Thane Fort to the Thane Central Jail

THANE FORT TO THE THANE CENTRAL JAIL: A TRANSITION AND PRESENT SITUATION – VAIBHAV D. ADHYARU K. V. PENDHARKAR COLLEGE OF ARTS, SCIENCE AND COMMERCE, DOMBIVLI, MAHARASHTRA, India. THANE FORT TO THE THANE CENTRAL JAIL: A TRANSITION AND PRESENT SITUATION The existence of Thane city appears in the  global history since the 9thcentury A. D. Thane city has a rich cultural heritage, mythological background, followed by a large number of events of historical importance, archeological collectives that have contributed to the enrichment of the history of Thane city.The city was then known as ‘Shreesthanak’. The Thane Central Jail, originally a historical fort was constructed by Portuguese in 1730 A. D. The prison, which was earlier a fort named Thane Killa, is associated with the Indian Freedom Struggle and is also one of the heritage structures of the city. The 279 year old monument was constructed by the Portuguese for the protection of Sashti Island on 13. 5 acres of land. The Portuguese ruled Thane for over 200 years, from 1530 to 1739 A. D. During this period Thane was known as ‘Kalabe De Tana†.In January 1737, Chimaji Appa, the Peshwa’s brother, took command of the Marathas troops and inspite of obstinate resistance, captured most of the northern forts, Katalvada, Dahanu, Kelve, Shirgaon and Tarapur, whose walls were scaled by the Marathas. On May 4th, the Portuguese hoisted the white flag and of their officers met Chimaji Appa for arranging terms of surrender. On 28th December, 1744 the British conquered Thane city and its fort. Marathas lost the Third Anglo-Maratha War in November 1817 between the British East India Company and the Maratha Empire in India.The war left the company in control of most of India. British Victories were swift, resulting in the breakup of the Maratha Empire and the loss of Maratha independence. The Peshwa was defeated in the Battles of Khadki and Koregaon and he was forced to flee. It was conver ted into jail in 1816 by the British. When Britishers got controlled all over the entire India, they started to use the Thane fort as central jail so that they can arrest and jail the nearby freedom fighters, criminals for going against their system. Many well known freedom fighters were imprisoned in this jail during the time.On 19th April, 1910 noted freedom fighters like Veer Anant Laxman Kanhere, Gopal Krishnaji Karve and Vinayak Narayan Deshpande were hanged to death in the central jail for killing the then Nasik District Collector Jackson. Noted freedom fighter Veer Savarkar was also imprisoned in central jail but later he was shifted to Andaman Cellular Jail due to the security reasons. Other freedom fighters like Chaphekar Brother and Mahadev Ranade were hanged for killing W. C. Rand for his atrocities in Poona. Prominent freedom fighters like Vasudev Balwant Phadke, Senapati Bapat, Saneguruji were also lodged in this jail.Later Indian Government continued that fort to be us ed Thane Central Jail as a district jail to jail the criminals of Thane District. Thane Central Jail is a huge campus and having different departments for the upliftment of the criminals. Personalities like Harshad Mehta and Sanjay Dutt were also imprisoned at Thane Central Jail. Various departments have been working efficiently for the smooth functioning of the Jail:- The Superintendent, Thane District Prison, is vested with the executive management of the prison in all matters relating to internal discipline, economy, labour and punishment.The Superintendent is assisted by the executive, medical, ministerial and technical staff. CLASSIFICATION:- There is one district prison and eleven taluka sub-jails in Thane District. The prison at Thane has been classified as a district prison [Class I], This prison is only meant for the confinement of the under trial prisoners and prisoners sentenced upto 5 years. CLASSFICATION OF PRISONERS:- Prisoners are classified as class I or class II by the court after taking into consideration their status in society and also the nature of offence. They are further classified as casual, habitual, under-trial and security or detenue.There is no separate class of political prisoners but certain rules which do not allow the grant of facilities and privileges on the score of length of sentence are relaxed in their favour under the specific orders of government. On admission, a prisoner is examined by the medical officer and is classified as fit for light, medium and hard labour. Prisoners are employed in prison industries, prison farms and prison maintenance services. Vocational classes are also organized in the prison. EDUCATION:- Literacy classes are conducted for prisoners and necessary facilities are provided to prisoners at government cost.RECREATIONAL AND CULTURAL ACTIVITIES:- Recreational programmes like physical training parades, documentary and full length films, folk dances, kalapathak and games are organized for the enterta inment of prisoners generally in a month. Besides, newspapers are also supplied to the prisoners. Emphasis is always laid on the maintenance of good discipline in the prison. JAIL INDUSTRY:- The long term prisoners in Thane Central Prison are provided with creative work including handicrafts and industries. The chief of these industries include textile, carpentary and tailoring. Most of the products are supplied to various government departments.The tailoring unit in the jail supplies readymade garments to the post and telegraph department and to the police. COTTON CLOTH AND CARPETS:- Weaving is the chief industry in the jail. There are around 14 looms for manufacturing carpets, blankets etc. CARPET AND PUNJA CARPETS:- Carpets are woven on pit-looms and are called loom carpets. The workers or prisoners move on horizontally as the weaving process goes on, completing the carpet. It is in great demand both from government and in the public. CARPENTARY:- This section is worked on job ba sis. A group of two or three prisoners do the planning and assembling job. CONCLUSION:-In this way Thane Central Jail administers work of the inmates/prisoners, So that the prisoners develop their skills through the routine work. Historically important memo i. e. martyrs memorials are not open for the citizens. There memo may be the inspiration for the citizens so it may create awareness about the national movement. Hence, it is necessary to make them accessible for the citizens. The present day physical condition of the jail is not in proper condition, so it should be repaired properly as soon as possible to maintain the condition of the jail. However, today the fort is a very busy place on account of being a jail.

Government to Limit Use of Cars Essay

Government agencies have been told to stop using official vehicles one day a week based on their license plate numbers, according to a notification for an energy-saving and emission reduction program to be implemented across the country.†¨Ã¢â‚¬ ¨The program, part of government efforts to protect the environment and promote sustainable development during the 12th Five-Year Plan (2011-15), was published on the central government’s official website Tuesday.†¨Ã¢â‚¬ ¨According to the program, the measures were specially designed for various fields, such as enterprises and schools.†¨Ã¢â‚¬ ¨Some Web users applauded the government’s efforts, while others questioned the feasibility of limiting the use of government vehicles. Lian Peng, a freelance writer, wrote on his Sina Weibo microblog that it was difficult to distinguish private cars from official ones, and the ban would result either in drivers using two license plates, or the government buying more vehicles. †¨Ã¢â‚¬ ¨A pilot project for government agencies to use bicycles will be launched. Government workers’ autos were also encouraged to be parked one day a week based on plate numbers.†¨Ã¢â‚¬ ¨Niu Fengrui, director of the Institute for Urban and Environmental Studies at the Chinese Academy of Social Sciences, praised the positive efforts made by the government to reduce emissions. However, such efforts would not have apparent effect, Niu told the Global Times Tuesday.†¨Ã¢â‚¬ ¨Niu suggested that the root of the problem was energy supply, and the fundamental approach should be to develop technologies and adopt better equipment to improve efficiency, as well as change lifestyles and production methods.†¨Ã¢â‚¬ ¨Zhu Lijia, director of the public research department of the Chinese Academy of Governance, told the Global Times such measures will not actually promote the reform of the official vehicle system, and would not impact the core of the system. Military told to cut emissions The government’s efforts to save energy and reduce harmful emissions have spread to a new front: the country’s military.   The People’s Liberation Army (PLA) and armed police should work to build energy-efficient barracks and develop energy-saving models for logistics, consumption and training, said a nationwide emission-reduction plan. â€Å"Efforts to save resources in the military are an important part of the country’s energy-saving and emission-reduction efforts,† the plan said. It lays out that the PLA will scale down administrative expenses, make greater efforts to conserve fuel, procure environmentally friendly products and recycle military uniforms. PLA garrisons will coordinate their use of civilian vehicles with local governments to enhance transportation efficiency. Xinhua Introduction It is possible that no invention has had as profound an effect on society as the passenger automobile. It did not take long after its introduction in the early part of this century for the auto to quickly become the primary means of transportation in the United States, where there are now 752 motor vehicles for every 1,000 people (World Almanac 211). While no other country can match the excessive automobile use of the U.S, it’s not for lack of trying. Even in China, where the use of bicycles by its citizens is legendary, the number of cars has been doubling every five years for the past 30 years (World Resources Institute, hereafter â€Å"WRI† 172). But reliance on cars is not without its problems&emdash;the most obvious being air pollution and energy consumption. Pollution: General Pollution by cars causes lung cancer, respiratory problems, urban smog, and acid rain (Brown 25). By 1970, after decades without government regulation, air quality had become a serious problem. The first federal Clean Air Act was passed during the Nixon Administration to curtail the ever-increasing amount of pollution caused by automobiles and industry, and Congress passed an updated version in 1990 (WRI 182). However, the Clean Air Act didn’t prohibit pollution; it simply defined an â€Å"acceptable† amount. Further, the legislation addressed only certain airborne contaminants, while ignoring others. Perhaps most significantly, although bad air was outlawed, it still exists. More than half of the people in the U.S. live in areas that failed to meet federal air quality standards at least several days a year (30 Simple Energy Things You Can Do to Save the Earth, hereafter â€Å"30 Simple Things,† 11), and around 80 million Americans live in areas that continually fail to meet these standards (WRI 63). Despite the Clean Air Acts, the reality is that air pollution continues to be a major public health problem. As bad as the air is in the U.S., in other countries which have waited too long to address the pollution caused by cars, it’s worse. Mexico City, Sà £o Paulo, New Delhi, and Bangkok are grappling with serious air problems. And much of that pollution is caused by private automobiles (Brown 25). Pollution: Ground-Level Ozone One way cars create pollution is by contributing to the amount of ground-level ozone (not to be confused with the atmospheric ozone layer). In the atmosphere, the ozone layer shields the planet from harmful ultraviolet radiation rays. But on the ground, ozone is another matter, causing hazy smog and respiratory problems. Most ozone pollution is caused by motor vehicles, which account for 72% of nitrogen oxides and 52% of reactive hydrocarbons (principal components of smog) (30 Simple Things 11). The seriousness of ground-level ozone should not be underestimated. According to the World Resources Institute: Ozone pollution has become widespread in cities in Europe, North America, and Japan as auto and industrial emissions have increased. †¦ Breathing ozone concentrations of 0.012 ppm&emdash;levels typical in many cities&emdash;can irritate the respiratory tract and impair lung function, causing coughing, shortness of breath, and chest pain †¦ Evidence also suggests ozone expo sure lowers the body’s defenses, increasing susceptibility to respiratory infections (65). Pollution: Lead Cars also pollute by emitting lead from leaded gasoline. Although the use of lead in gasoline is banned in the United States, leaded gasoline is common in other countries. In fact, of the countries for which data is available, 43% use nothing but leaded gasoline. Many of the rest use at least some leaded gasoline in their energy mix. This is a definite cause for concern: One of the oldest metals used by humans, lead is a cumulative neurotoxin that impairs brain development among children and has been connected to elevated blood pressure and resulting hypertension, heart attacks, and premature death in adults. Emissions from vehicles is the largest source of lead exposure in many urban areas (WRI 266-267). The effects of all this pollution on human health are unsettling. A study of U.S. cities found that mortality rates were 17-26% higher in cities with the dirtiest air compared to those with the cleanest air. Not surprisingly, the study also found correlations between bad air and lung cancer and cardiopulmonary disease. The risks translate roughly to a two-year shorter life span for residents of dirty-air cities. On a global basis, estimates of mortality due to outdoor air pollution range from about 0.4-1.1% of total annual deaths (WRI 63-64). In the U.S., 30,000 people die every year from automobile emissions (â€Å"Bicycling and Our Environment† 1). [Also see our separate page on lead.] Pollution: Global Warming Perhaps even scarier than the direct damage to our bodies from auto pollution is the fact that car emissions are contributing to an overall warming of the entire planet, which could destroy the world’s food chain. Cars emit carbon dioxide (CO2), a heat-trapping gas. In fact, they emit a lot of it: 20 pounds per gallon of gas burned (NRDC 12, Zuckermann 29). Atmospheric concentrations of CO2 have increased by 30% since preindustrial times, and much of that increase is directly related to the burning of fossil fuels. According to the Worldwatch Institute: â€Å"CO2 levels are now at their highest point in 160,000 years, and global temperatures at their highest since the Middle Ages† (Brown 26). The effects of this global warming are frightening: rising sea levels, dying coral reefs, spreading of infectious diseases, and extreme weather conditions, including droughts, rare forest fires, historic floods, and severe storms. Even more frightening, these events are not just pr edictions&emdash;they’re happening right now (Brown 26). Energy Use The amount of energy used by automobiles is staggering. Transportation of all types accounts for more than 25% of the world’s commercial energy use, and motor vehicles account for nearly 80% of that (WRI 171). In numerical terms, the figures are hard to comprehend. The world used over a trillion liters of motor gas in 1995. And the U.S. accounted for 46% of that total (WRI 266-267). In fact, America’s gasoline consumption easily outstrips its production. The U.S. currently imports over half its oil (52%) even more than it did before the oil crises of 1973 and 1979. This dependence on foreign oil has significant economic consequences, and many observers feel that protecting â€Å"our† right to oil was the real reason for the U.S./Iraq war of 1991. Americans use large amounts of gasoline not just because they drive so much, but also because they’re extremely wasteful about how they drive. The NRDC notes: â€Å"Most cars on the road carry only one person. In fact, we have so much extra room in our 140 million cars that everyone in Western Europe could fit in them with us.† If every commuter car in the U.S. carried just one more person, we’d save eight billion gallons of gas a year. The one-person-per-car scenario also greatly contributes to traffic congestion, which in turn wastes even more energy&emdash;about three billion gallons of gas a year (30 Simple Things 52-53). But changing Americans’ habits doesn’t seem likely any time soon, as the failure of â€Å"High-Occupancy Vehicle† (HOV) lanes makes clear. To encourage commuters to carpool, some communities have designated one lane of traffic on certain roadways as HOV lanes. Commuters can drive in this lane only if there are at least two people in the vehicle. The reasoning is that commuters will want to carpool so they can ride in the uncongested HOV lane rather than being stuck in traffic in the normal lane when riding by themselves. But as Michael Bluejay points out, these lanes don’t always succeed in encouraging carpooling. A friend and I recently had occasion to drive through Dallas during rush hour, and I had my first opportunity to see how an HOV lane worked. Basically, it didn’t. We passed hundreds and hundreds of single-occupant cars in the regular traffic lanes as we zoomed by in the practically-empty HOV lane. It struck me as really crazy: Whenever I try to encourage people to ride bikes more and drive less, they always whine to me about how ‘convenient’ it is to drive. Well, exactly how ‘convenient’ is it to sit in your car at a complete standstill, adding 30-60 minutes to your morning commute? That’s convenience?! The experience demonstrated to me how far people were willing to go to avoid carpooling. They were willing to sit there like morons, stuck hopelessly in traffic, for the ‘luxury’ of being the only person in their vehicle. Although I was disappointed that the HOV lanes didn’t seem to work, I was at least pleased to realize that all those greedy motorists were being punished with even more traffic congestion, since the HOV lane meant that there was one fewer lane to move all those cars. Summary Automobiles are responsible for a tremendous amount of air pollution and wasted energy. These problems impact people all over the world, both motorists and non-motorists alike, by affecting their health, their economies, and their communities. Legislation to address air pollution has been only partially successful, and air quality continues to be a major concern in countries all over the world. As for energy use, one can only hope that world leaders find a better way to address this problem than fighting wars over an increasingly shrinking supply of oil.

Car pollution statistics point to ground pollution, resource reduction (mining and petroleum products), and health issues as other problems derived from out motorized society. Air quality is an important reason to pay attention to car pollution, but there are other reasons too.| Car pollution is considered by most people to be a decreasing problem, but it’s actually increasing, due to the large number of cars that are driven each day. Measures are being taken to reduce air pollution, including the manufacture of hybrid cars, the creation of new environmentally friendly fuels, and more, but those measures don’t touch all of the car pollution issues. Learning about car pollution statistics can open your eyes to the myriad problems. If you realize the importance of making changes in your life and car driving habits, then you can make changes to help decrease the amount of car pollution that you release into the air. * FTIR Gas AnalyzerGas purity and emissions monitoring by MKS Instruments On-Line Analyzer†¨www.ccrprocessproducts.com/FTIR†¨ * Car pollution statistics can give you the knowledge that you need to compel you to make changes in your life to lessen your impact upon the environment. Here are a few car pollution statistics that you need to be learn about and be aware of: * SUV’s release up to forty-seven percent more car pollution than the average-sized car. * The amount of car pollution that is released from cars is much more than the amount of pollution released by a nuclear power plant. * Ozone pollution is primarily due to the pollution that is released by cars. Seventy-two percent of nitrogen oxides and fifty-two percent of hydrocarbons, which is a component of smog, are released by cars. * The Journal of Epidemiology and Public Health published a study that suggested that most childhood cancers are caused by air pollution, which can be caused by cars and more. * There are 752 cars for every 1,000 people in the United States. * In China, the number of cars that are driven has doubled every five years for the past thirty years. * Thirty-thousand people in the United States each year die from conditions that are caused or exacerbated by car pollution. * Half of the people in the United States live in areas that fail to meet federal air quality standards at least several days a year. * Eighty million people live in areas that are continually not living up to these standards. * SUV’s release 28-gallons of carbon dioxide into the air for every gallon of gasoline that is used. * Car pollution has numerous effects, both physically and environmentally, like acid rain, smog, lung cancer, and respiratory problems. As you can see from the above car pollution statistics, cars have a huge impact upon the health of the citizens, the air, and the environment. That is why it is so important that we find ways to make changes in our lives to help decrease the amount of pollution that we release by driving our car. By using alternative fuels, considering hybrid cars, driving less, and more, you can help make your impact upon the world a little less harsh. Consider these car pollution statistics the next time that you get into your car. You may find that your trip is not as important as you think. Energy Consumption and the Environment Impacts and Options for Personal Transportation (Revised 2-4-96) In 1973, petroleum shortages caused by the OPEC oil embargo launched the world’s industrialized nations on a search for more efficient homes, factories, and transportation systems. After two decades of attempts to economize, energy use in the residential sector is about the same, industrial energy use is down, and transportation energy use is up. Today, we are more concerned with the other side of the coin – the environmental problems and long-term economic perils of unbridled energy consumption.Trends in Transportation Energy Consumption:Transportation now consumes more than 20% of the world’s total primary energy and produces much of the world’s air pollution. In just 30 years, the number of cars in the world will soar from today’s 400 million or so, to more than one billion. Private transportation will then need 2-1/2 times more energy and produce 2-1/2 times more air pollution. If global trends are projected to year 2100, the world will need 10 times more total energy, and transportation will consume 40% of this much larger pool.(1)Energy Use, Global Warming, and Climatic Changes:Energy use and emissions trends point to significant economic, political, and social problems for future generations. The greenhouse effect alone could have devastating effects on economies. Without intervention, the buildup of greenhouse gases could reach twice the pre-industrial level as early as 2030. The resulting global warming effect could raise sea levels enough to threaten wetlands, increase coastal flooding, and accelerate coastal erosion. The Intergovernmental Panel on Climate Change (IPCC) estimated that sea levels will rise an average of 6 to 20 inches by 2050. In addition, many unmanaged ecosystems will probably be lost. Changes in rainfall patterns will likely result in more severe droughts, more intense tropical storms, and ultimately, dislocations and reductions in agricultural output. (Despite the increased crop yield associated with higher carbon dioxide levels, the resulting climatic changes are expected to shift agricultural production to regions having less productive topsoil, which would then result in diminished total yields.)About 75% of human emissions of carbon dioxide, the most important man-made greenhouse gas, is caused by the use of fossil fuels. Fossil fuel use has caused an imbalance in the earth’s normal carbon cycle. Normally, biologic growth absorbs carbon from the environment and then releases it back into the environment when it decays or is burned. New growth then absorbs the carbon again, and the amount of carbon in the environment remains roughly the same. Since the last ice age, the level of carbon in the atmosphere (in the form of carbon dioxide) has varied only about 5%. However, fossil fuel use has upset the balance.Over the earth’s history, large amounts of carbon had been removed from the environment and become locked away beneath the surface where it was ultimately transformed into fossil fuel deposits. Since the industrial revolution, humankind has been removing these deposits, burning the fuel, and releasing the carbon into the atmosphere. The result is a rapid buildup of atmospheric carbon dioxide that is unprecedented in the history of human life on earth. No one knows the precise effects, b ut for better or for worse, average temperatures will increase and global weather patterns will change. Limited Supplies of Traditional and Inexpensive Energy:Nearly 40% of the world’s energy now comes from petroleum, and another 21% comes from natural gas.(2) Together, these finite natural resources supply about 60% of the world’s energy. If oil and natural gas consumption continued to double every 15 to 20 years as it had for the 100 years preceding 1973, the earth’s entire original endowment of these resources would be 80% depleted in another 30 years or so. As early as 1970, new oil and gas discoveries had dramatically declined and have remained low. In the ’80s, experts estimated that U.S. reserves would last about 35 years at existing pumping rates. More recently, estimates have been revised downward. Considering known reserves and estimated undiscovered deposits, U.S. oil will be depleted in about 10-12 years at present pumping rates. And new finds will make little difference on a worldwide scale. A new Prudhoe Bay discovery would provide the world with about six months’ oil supply, and a new North Sea find would equate to about three years’ supply.(3)Each year, the demand for oil is increasing by an amount equal to Kuwait’s entire annual production, and for the first time, OPEC has no substantial excess production capacity. Because of declining and more costly-to-recover petroleum reserves, prices are expected to begin rising in the mid to late ’90s, and continue to rise thereafter.(4)Alternative Fuels:The challenge of alternative fuels is primarily an economic one. Although the volumetric cost of methanol (made from natural gas) and ethanol (made from corn) is on par with gasoline, a car running on ethanol consumes 50 percent more fuel and an ethanol car consumes about twice the fuel per mile traveled, in comparison to a car running on gasoline. Consequently, per-mile fuel costs are greater. Natural gas is less costly on a per-mile basis than toda y’s gasoline, but supplies are finite and the high cost of natural gas vehicle systems generally offset the lower cost of the fuel itself. Although environmentally friendly, hydrogen is both technically and economically challenging due to its high production costs and the difficulty of storing hydrogen on-board vehicles. Alternative fuels do not save primary energy, but they are cleaner than gasoline. Carbon dioxide levels remain essentially unchanged when alcohol fuels are made from renewable biological feedstocks.Renewable Fuels:Renewable biomass fuels, such as ethanol and methanol, may become economically competitive with petroleum motor fuels by year 2000. But much remains uncertain about the world’s capacity to produce biomass in quantities sufficient to meet future energy needs. Already, about half the world’s solar energy captured by photosynthesis is used by humans, primarily for food and forest products. Total primary energy use in the U.S. amounts to about 31 times more energy than is harvested as crops and forest products, and about 40% more energy than is captured by all forms of U.S. vegetation, combined. Considering all agricultural crops, forests, lawns, gardens and wild vegetation, the energy contained in annual U.S. vegetation growth totals about 54 quads (quadrillion BTUs), and in year 1990 total U.S. primary energy consumption amounted to approximately 81 quads.Because of limitations in water supplies, nutrients, and arable lands, the amount of energy obtainable from the world’s agricultural resources is limited. Even in the U.S., which has more arable land per capita than any other nation on earth, it may be infeasible to produce biomass fuels in quantities sufficient for the nation’s energy needs. According to Dr. David Pimentel, Cornell University, the U.S. has the agricultural capacity to support a population of about 200 million on biomass energy – only if per capita energy consumption were reduced to half its present level. Worldwide, the ability of the ecosystem to sustain a population at an equivalent of U.S. consumption in the ’90’s is probably limited to about two billion people, or one-third of the existing population.(5) Unfortunately, U.S. population is expected to reach 500 million in 60 years, and worldwide population will reach 12-15 billion near the end of the 21st century. Economic Implications:The world is entering a period of escalating consumption, declining reserves of traditional energy feedstocks, higher energy costs, and increasing environmental stress, which could have vast economic, political, and social ramifications. As environmental limitations are approached, ecosystems become more unstable. In the future, ecosystem management and environmental maintenance will become more the responsibility of humans rather than nature. The economic impact of higher energy costs will be compounded as the cost of environmental protection and repair is included in the fundamentally higher cost of energy. As a result, varying degrees of negative economic effects are likely.Ultimately, a fundamental restructuring of the way in which energy is produced and consumed, as well as its value and role in the economy, must occur, regardless of the particular energy technology. Reducing the energy intensity of industrialized societies is the most environmentally sound and least economically harmful strategy. Energy use must be constrained if the interrelated problems of energy supplies, environmental degradation, and economic well-being are to be solved.Transportation’s Role:Transportation is essential to modern economies, and that sector is almost totally dependent on oil as a source of energy. The ability to freely and inexpensively move goods and people is a fundamental link in the economic chain. Today, large changes in the price or supply of oil send shock waves rolling through the world’s financial institutions. Transportation is the most rapidly growing consumer of the world’s energy, and the largest share of transportation’s energy goes to passenger travel. In developed countries, passenger travel accounts for about 70% of the total energy consumed by transportation.The Automobile’s Impact on Transportation Energy Consumption:The automobile is responsible for nearly 90% of the energy consumed for travel in the U.S., about 80% in Western Europe, and nearly 60% in Japan.(6) Today, there are approximately 400 million cars in the world, and sometime around year 2030 the world’s automobile population will surpass one billion. If driving habits remain unchanged, cars will have to become nearly three times more energy-efficient by 2030 just to maintain that sector’s present consumption. If energy use trends are projected to year 2100, transportation would then have to be twenty times more energy-efficient, which roughly equates to 400 mpg cars (automobile fleet-average fuel economy is now about 20 mpg).Cars in the U.S. have become more energy-efficient over the past two decades, but other developed countries are losing ground and actually consuming more fuel per passenger mile traveled.(7) Europeans are turning more to private cars, and as a result transportation trends and energy use patterns are converging with those of the U.S. But the greatest increase in transportation energy consumption will occur in the developing world. By year 2010, India is expected to have 36 times more cars than in 1990. China will have 91 times more cars, Mexico will have 2-1/2 times more cars, and Eastern Europe and the countries of the former U.S.S.R. will probably double their automobile population. The rest of the developing world will experience a 300% increase over the same period. In comparison, the number of cars in the U.S., Canada, Western Europe, and Japan will have grown by only 12%-15%.(8)The Automobile’s Role in Atmospheric Pollution:In a typical U.S. city, motor vehicle emissions account for 30%-50% of hydrocarbon, 80%-90% of carbon monoxide, and 40%-60% of nitrogen oxide emissions. Cars and light trucks are responsible for about 20% of the nation’s carbon dioxide, which is a powerful greenhouse gas. Motor vehicle carbon emissions are essentially proportional to total fuel consumed.(9) Unfortunately, in the coming decades the greatest growth in the automobile population will occur in developing countries which can least afford clean technologies. The United Nations Fund for Population Activities estimates that, because of rapidly increasing automobile populations, developing countries will be emitting 16.6 billion tons of carbon dioxide annually by year 2025, or about four times as much as developed nations. Problems Are Interdependent:Transportation energy consumption and environmental health are interrelated issues. Relieving the demand side of the equation simultaneously relieves the rest. If vehicle fuel economy were doubled, for example, transportation emissions would be essentially cut in half, even if there were no improvement in emission control technologies. If petroleum consumption were cut in half, reserves would be effectively doubled, even though no new deposits had been discovered. With a doubling of vehicle fuel economy, the same number of vehicle miles could be supported on half the investment in exploratory drilling, half the recovery, refining, and delivery expenses, and half the damage to the environment. The same interrelationships would exist with alternative energy sources, regardless of the particular technology.Although each problem, from emissions and resource burdens to economic factors, may yield to their own targeted efforts, alleviating the fundamental proble m simultaneously reduces the entire spectrum of associated difficulties. The Automobile as a Transportation System:Mass transit is often mentioned as an alternative to private cars, but the most effective mass transit system in the world is the automobile. An automobile transportation system provides schedules and routes that are tailored to individual needs. In addition, users individually purchase, maintain, and fuel the transportation device, and only the relatively inexpensive roadways require public funding.The primary tradeoffs for this otherwise ideal system are high energy intensity and high emissions.(10) However, if the automobile is to survive as an economically sound and viable transportation system its energy consumption and harmful emissions must be reduced.The Potential Impact of New Technologies:Today, automobiles operate at approximately 15% efficiency, which means that about 15% of the energy contained in the fuel is delivered to the drive wheels as useful work. According to the best estimates, it may be possible to double automobile energy efficiency (using conventional powertrains) to about 30% before we run out of ideas. At 30% powertrain efficiency a 20- to 25-mpg sedan would then achieve fuel economy of 40 to 50 mpg. Advanced power systems and reduced vehicle roadloads are necessary in order to make significant gains in automobile energy intensity.Electric cars produce significantly fewer harmful emissions, and they save about 10% to 30% in primary energy (over the entire energy chain). Advanced fuel cell vehicles using methanol reformed on-board into hydrogen may be as much as 2-1/2 times more efficient than today’s cars. Practical automobile fuel cells, however, present enormous economic and technical challenges.In the final analysis, technology alone may not be able to solve the world’s energy problems: partly because of the limitations of technology, but primarily because of the economic realities of alternative energy systems. And even the most optimistic estimations of the energy savings obtainable with advanced-technology systems still fall short of accommodating the long-term forecasts of transportation’s energy needs.A reduction in personal transportation energy intensity is essential in order to reduce the economic impact and technical hurdles of new energy systems and more costly energy supplies. Energy conservation is the most economically sound and environmentally friendly option.Factors That Affect Personal-Transportation Energy Consumption:Transportation energy consumption depends on the mass being transported and the distance it is transported. The technologies employed determine the efficiency at which the mass is transported. Consequently, energy consumption can be reduced by developing more efficient transportation technologies, or by reducing the transported mass and/or the distance traveled.The factors of distance and mass are determined largely by social and economic structures, and by vehicle layout and configuration. In order to reduce the distance and mass factors, Paulo Solaria envisions self-sufficient cities like Arcosanti in Arizona in which automobiles are no longer needed. Telecommuting, or working at home and transferring information, rather than people, is another approach designed to reduce overall distance and mass.With revised architectures, and new business and social structures, it is possible to significantly reduce society’s transportation energy needs. The difficulties of such revisions arise from the economic burdens of restructuring cities, and the psychological resistance to large scale changes in social and business structures. The technologies, however, are largely available or just on the horizon.Reducing the transported mass, independently of the distance traveled, can also fundamentally reduce transportation’s energy requirements. Moreover, mass reduction need not affect travel habits, social and business structures, or the architecture of cities. The opport unity for a large reduction in mass becomes apparent when one considers that the vehicle itself is responsible for approximately 92% of the transported mass, while the occupants account for only 8%.(11) Most of the automobile’s energy is consumed to transport itself. Mass reduction alone can save more energy than the most advanced powertrain concepts.Matching Vehicle Size to Trip Requirements:From the traditional perspective, the â€Å"identified problem† contributing to the automobile’s high energy intensity is low vehicle occupancy. Transportation energy intensity is a measure of the energy consumed per passenger mile traveled. When a vehicle is lightly loaded, energy intensity goes up because the vehicle consumes about the same amount of energy (fuel), regardless of the number of occupants. Operating large, multi-passenger cars with only one or two occupants is therefore considered the most wasteful habit affecting the world’s consumption of transportation energy.Worldwide, automobiles operate, on average, with about 1.6 to 1.8 occupants. In the U.S., approximately 87% of all automobile trips occur with two or fewer occupants. The average for work related trips is 1.1 occupants per vehicle. One- and two-occupant trips acco unt for approximately 83% of all vehicle miles traveled in the U.S.(12)If the same number of travelers were condensed into half the cars (car pooling), total automobile energy consumption would be reduced by half. But condensing occupants into fewer vehicles essentially defeats the automobile’s primary benefit. Trips must then accommodate the needs of other occupants, and the automobile is no longer a private and personal means of transportation.Traditionally, occupancy-rate is considered a behavioral by-product and therefore outside the bounds of vehicle technology. However, if the â€Å"identified problem† were redefined, it can easily become a simple technical problem. If the definition were â€Å"inappropriate vehicle size† (rather than underutilization of large cars), the solution would then be to resize vehicles so they more closely match trip requirements. Since one- and two-occupant trips predominate, it naturally follows that a category of smaller vehicles designed for one- and two-occupant local and commuting trips would be beneficial.Low-Mass Vehicle Safety:Small, lightweight cars are normally associated with an increased risk of harm. Traffic accident statistics generally support the relationship between vehicle size and injury/fatality rates, with the potential fo r harm increasing in proportion to the decrease in vehicle size. (The exception is in Japan, where a special category of lightweight â€Å"kei† cars actually have a lower fatality rate than conventional large cars.) But with better vehicle designs, historical data can quickly become outmoded. Cars built today are four times safer than vehicles built in 1969, and they are approximately 10% smaller and 20% lighter. This is due primarily to improved safety engineering and modern safety systems.Although occupant protection becomes more challenging as vehicle size is reduced, it is technically feasible to produce significantly smaller and lighter vehicles that have a high degree of safety. Advanced â€Å"hard shell† concepts designed to increase low-mass vehicle safety are already under development in Switzerland. This new approach utilizes a rigid exterior that is largely identical to the rigid passenger compartment of conventional cars. During a collision, the rigid exterior of the smaller car causes the less rigid deformation zone of the larger car to yield and absorb energy. Passenger ride-down space (for deceleration) in the low-mass car is provided inside the vehicle, rather than by the traditional exterior deformation zone. Occupant deceleration is controlled by elastic restraints and air bags. (13)Vehicle use patterns and operating environment are also important. Cars that operate primarily in the urban environment do not necessarily have to match the crashworthiness of larger cars in order to provide equally safe transportation.New Products and New Market Appeals – The Giant Oil Well Under Detroit:Market positioning, the implied messages in a product’s theme and advertising appeals, can capitalize on today’s environmental and energy concerns, and ultimately have a powerful effect on energy consumption and pollution. The necessary consumer motivations and interests already exist. A shift in thinking that disengages manufacturers and consumers alike from the association of size and mass in relation to value in automobile design is an essential part of reducing transportation’s energy consumption.Significantly smaller and lighter cars, both electric and conventionally powered, are normally envisioned as cheap, underpowered, and unsafe vehicles that have little appeal. Once this premise is accepted, vehicle attributes consistent with the vision naturally emerge and an outline of market potential, profitability, and even vehicle styling and safety then follows suit according to the core idea. These details can quickly change when the vehicle and the market are seen from a different perspective.By adopting a new perspective on automobile design, new marketing opportunities and new product ideas can begin to take shape. By emphasizing innovative safety features, visually impressive driver information systems, advanced vehicle control and crash avoidance systems, and attractive vehicle layouts and styling, smaller urban cars and commuter cars can emerge as safe, marketable, and even superior, transportation products. Innovative product packaging and marketing appeals are essential for a successful transition to electric urban cars and fuel-efficient commuter cars.Despite today’s â€Å"green† orientation, sacrifice and conservation are not especially marketable attributes. New vehicle types must satisfy consumers’ complex psychological needs while appealing to their broad social concerns. Energy conservation and environmental protection must be positioned as an upscale product attribute, rather than as a necessary sacrifice in the name of economic and environmental health. Energy conservation and emissions reduction are not primary consumer benefits. When manufacturers address environmental concerns with attractive new vehicle themes that satisfy consumers’ psychological needs, a marketable new category of products will have emerged, and passenger-travel energy consumption could be reduced by nearly two-thirds.A Sustainable Paradigm for a Fully Industrialized World:Alternative cars alone will not create a system for long-term sustainability with the expected populations. Although transportation will be tomorrow’s largest single energy consumer (as much as 40% in the long term), combined industrial and residential needs will account for a larger portion of society’s total energy needs.Future generations will probably have to adapt to more expensive energy, and use the world’s resources more prudently. This does not necessarily point to a world of stifling scarcity, but more to a new sense of responsibility, and a new paradigm for product design and the lifestyles that interrelate to form the overall production/consumption/pollution matrix. Changes in attitudes and behavior patterns can have an enormous impact on the cost to the ecosystem in resources and pollution. Population control and new business and social structures are essential; and new technologies are needed as well.Today’s developed economies, which account for only one-fourth of the world’s inhabitants, have been fortunate to have abundant and cheap fossil energy supplies to fuel their transition into an industrialized world. In a sense, today’s developed societies are similar to yesterday’s pioneers, blazing the technology trail to a new frontier of sufficiency and sustainablity for the world’s future community of developed nations. Abundant and clean energy from nuclear fusion, along with fuel cell cars and rapid-recharging, extended-range, battery-electric cars, are probably the best hopes for meeting long-term transportation and energy needs. And new frontiers must be pioneered in attitudes and values, which ultimately convert to resource consumption and environmental degradation as they guide behavior. Just as alternative cars do not necessarily imply dull product design or reduced transportation quality, new values and social structures do not necessarily imply compromised lifestyles.

Guns in the US: The statistics behind the violence Essay

Americans love their guns, and they will love them until the end of time. But as years go by gun violence has increased throughout the U.S. Experts have yet to decide whether to ban guns altogether or would it be just plain impossible since Americans gun bearing tradition is so embedded that we could never give them up. Or could we just simply prevent guns from falling into the wrong hands? Gun violence has just gotten worse throughout the years. It seems like every day we hear a story about another â€Å"mass shooting† and there is a big possibility that we will never stop hearing it. Each day we hear the horrors of the stories of the children being in the crossfire or young adults being involved in these shooting. How could society mess up this bad that children are being killed for things that had nothing to do with them. Now that there are more and more cases involving gun violence, concerns are being known. How can people live safe when there are guns being used for the w orst almost every day? Americans have had the right to bear arms when the 2nd amendment in the Bill of Rights was adopted in December 1791. So, would it be so hard to implement stricter gun laws or just not have guns at all? The U.S owns more guns than any of the other countries even if it accounts for only 5% of the world’s population, the U.S. residents own 50% of guns in the world. Some people think that the more guns the more violence there would be. While others think that guns for self-defense, hunting and collecting them are a good reason to own a firearm. Why are shooting occurring INTRO Can anything be done about it? INTRO //////Will gun laws help this situation or is America to attached to having guns or will we ever give them up/////Can we take measures like not letting people with mental health have guns in their home? Or people who have been convicted of violent crimes Or no-fly lists Where have stricter gun laws been effective/ineffective How have the other countries addressed the gun issues? Stricter gun laws After a mass shooting, Australia passed the National Firearms Agreement in April 1996. A man with a semi-automatic killed 35 people and injured 18. After this law was passed Australia banned semi-automatic self-loading rifles and shotguns and had stricter incensing and registration requirements. Since the ban of 1969 rate of homicides; murder and manslaughter have fallen. People who can’t buy guns Felons can’t have guns. they can not live in the household with a gun. Someone who has been convicted of violent or gun-related misdemeanors. Abusers of alcohol or drugs. Severe mental illness. Americans who have threatened to harm themselves or harm others go through a background check to prevent them from having a gun for at least 6 months.

Top5 current domestic terrorism Thesis Example | Topics and Well Written Essays - 2000 words

Top5 current domestic terrorism threats(i.e.nuclear,bio,chemical,agriculture,etc) - Thesis Example Terrorism – and the threat of terror - can have political, social, and economic ramifications. Politically, terror can sow fear, destabilize governments and provoke various forms of retaliatory measures. States of all stripes – including modern liberal democracies – have responded to terrorist threats through the curtailment of civil liberties (United States post 9/11), the imposition of martial law (Canada during the FLQ crisis of 1970) and the wholesale destruction of communities (Iraq’s genocide of the Kurds in Halabja, 1988). Full-scale retaliatory measures, such as that which was practiced at Halabja using chemical weapons (between 3,000 and 5,000 people were killed one March afternoon), often indiscriminately target, kill and maim entire populations. Terrorists today are unencumbered by geographic boundaries and are able, through the use and abuse of modern technology, to sow damage and fear on a global scale. The terrorist of today is transnational and Al-Qaeda today provides perhaps the best example of a global terrorist network. Terrorism is also inherently destabilizing and wreaks havoc both politically and economically. It remains one of the most sustained and important threats to global security and world peace. Additionally, legal changes often ensue in the wake of terrorist acts and the United States has a history of implementing controversial legislation in the wake of terrorist acts (Chaliand 101-240). What is a terrorist and how does one define terrorism? The age old adage that â€Å"one man’s terrorist is another man’s freedom fighter† (Bergesen & Lizardo 39) remains true and the term terrorist has been notoriously difficult to define. Despite these challenges, a definition of terrorism is integral and must be defined to provide a theoretical basis to this essay. According to Dr. Mia Bloom, terrorism can be defined as â€Å"premeditated, politically motivated violence

Analysis of The Best Man Film Research Paper Example | Topics and Well Written Essays - 1000 words

Analysis of The Best Man Film - Research Paper Example They are a perfect way for humans to connect emotionally, communicate between each other, and highlight evil and good incidents in the society. Stories enable societies to pass important virtues, history through generations, and build strong relations. Stories are powerful tools, which if well narrated can posses enormous power that establishes a profound connection with the audience. Connecting with the audience is a crucial aspect in storytelling, which moves and creates lasting memories in the audience. Telling a compelling story is the sure way of ensuring that people do not forget the story. This is because the feelings and emotions from a superb story are inerasable. The Best Man film is an example of a compelling story, narrated in the form of a movie. It achieved this quality through the various aspects, which include proper selection of setting, themes, cinematography and directing. Perhaps, the producers achieved this through properly identifying a particular audience, thei r profound goal, and the particular message the writer wants to pass across. The best man film capitalizes on these aspects to bring out a superb connection with its audience. To start with, the film uses real-life characters to communicate with its audience. This is a realization that stories in films are about people. People are what the audience connects with, and the film achieves this goal using characters, which the audience appreciate and connect with completely. The directors of the film further, in the cinematography, exploit the use of characters to speak their story themselves. Through this way, the piece becomes relatable and personalized, which makes the film authentic and captivating. To keep the audience connected to the story and avoid boring them, ‘The Best Man’ creates suspense throughout its narration. The characters constantly stir up emotions by bringing out issues that the society highly appreciates. Throughout the film, the use of clear meaning an d direction provides a clear meaning and decisive moment. These entirely enable the movie to create cathartic moments with the end of each episode. This of course, leaves the audience craving for the next episode. The film does not leave out the theme either. The setting is in a society that is traditionally renowned to be romantic, a factor that captivates a sense of authenticity of the entire action. Filmsettings are an important area of concern for movie producers. The setting in the film affects its cinematography. In the production of any movie, there are things that are not possible to shoot both in full scale and in real time. Others come with an unacceptable expense in terms of time and money. Special effect is the domain of showing the impossible or impractical: the art of making things appear to have happened. Production effects, including mechanical, are those that producers can stage during the principal or second-unit photography; the crew can photograph in one pass usi ng unmodified cameras. Special photographic effects, often referred to as special effect cinematography, employ photographic techniques to achieve their illusion. They may call for modified production camera, a special process camera (used in optical printing houses and laboratories rather than on a set), unconventional lighting, fixed and travelling matters, bi-pack and optical printing. They also require unusual degree of creative resourcefulness. Because of the extreme care and precision required, a separate unit working at its own pace, without tying up production personnel and full-scale production sets, handles special effect cinematography. However, the most important reason why producers consign

As temperature increases the level of turbidity increases Lab Report

As temperature increases the level of turbidity increases - Lab Report Example 107). It can be said that it is the measure of how much light can pass on the water, and this may be influenced by suspending matter in the water; these may be sediments, organic matter, eroded soil, silt, industrial waste to mention a few. The particles resting at the bottom of water may also be stirred up by water movement, people or storm runoff. With levels of turbidity may indicate the water is unhealthy for aquatic life as light will not easily penetrate to the bottom. Introduction:Temperature may determine the conditions in which matter exists. Minute temperature changes in water may change the conditions and thus make the aquatic life hard to survive in. Temperature changes may also result from deforestation thus allowing more sun to directly shine in the water. Factories and other power plants use water as a coolant and later discharge it back to water sources, this changes the water temperatures. The above reasons were the inspiration for this experiment. The results: The results demonstrate that at 40 degrees Celsius the lowest level of turbidity were recorded. An average reading of 21.65 in the turbidimeter was recorded. At 10 degrees Celsius an average turbidity of 21.65 was noted, at 30 degrees Celsius an average of 21.72 value was recorded, our control was 20 degree Celsius which recorded a reading of 22.38 Conclusion: My hypothesis was that when temperatures increase turbidity of water also increases, this hypothesis should not be accepted as the results recorded did not show any correlation between the water samples taken and the level of turbidity. Recommendations: In the future this experiment should be done in a well controlled environment where the surrounding or confounding variables are well controlled so that they do not have an influence on the experiment.

Should the federal government provide health care for all citizens who Research Paper - 1

Should the federal government provide health care for all citizens who cannot afford their own - Research Paper Example President Obama has put forward measures to adopt such a system but it has not been welcomed by the judiciary and other stake holders of the nation. This move by the president is under scrutiny, in this writing we will focus on whether US can adopt such a system or they are better off without it. The above graph shows that the benefits provided by employers to their employees in private organizations with US has declined, and there has been a steep decline in the amount of health benefits provided by these companies to their employees (Mauersberger 2012). Those in the favor of such a system state that the number of people within US who are living without health care insurance has elevated to the figure of 45 million (Washington, 2000). Organizations are even trying to cut their cost by not providing health coverage in their compensation plan to the employees. Decrease in the rate of wages and layoffs have even promoted individuals and employees of US to live without an insurance plan. All these events have taken place because insurance providers have increased the rate of premiums associated with health plans. Citizens of US do get free medical services for those diseases and illnesses that are not covered by health insurance providers. But there are those who can not purchase insurance services, these people need to be covered by the government otherwise their quality of life will continue to deteriorate. Those individuals and businesses that have already purchased health insurance have to end up paying very high rates of premium. If businesses continue to spend huge amount of their money as premiums, they will have lower amount of money to conduct investment activities and provide employment. Individuals who are paying loads of money as premium for health coverage are spending less on food and other necessities which is resulting in failure of businesses. Thus

Personal Finance Research Paper Example | Topics and Well Written Essays - 2500 words

Personal Finance - Research Paper Example The investment period is one month starting on Thursday 1st May 2014 to Saturday 31st May 2014. It is mandatory that we return the funded amount at the end of the investment period and hence as a group we have to select a portfolio of assets to invest in that will enable us to earn income that is above the inflation rate at the end of the period. We have an option of investing on either or all of the available investment options which are; Stock Market Investment (National/International), Bank deposits (Only Non-Islamic Qatari Banks), Gold & Other Metals, Bond / Debenture Investment International Market) or Forex Market (Currencies). In selecting among the options we consider the tradeoff between risks faced and the potential returns. This paper focuses on the major investment portfolios and their returns with an aim of determining the profitability of the various investments. It will be useful to the group members to identify the significance of investing in case the returns are positive. The main aim of investing this amount is to for capital growth. Our wish is for the amount to grow at a higher rate than the inflation rate within the month of May. From the returns we can buy more assets in the future and also use the incomes to support our lifestyles. We therefore are to consider investments with stable incomes and low risks on our original investment. We need to select the best mix of the available investment opportunities that will give us maximum returns and expose us to minimum risks. A higher percentage of the amount should be invested in less risky investments which in most cases result to lower returns. It is also important to invest in risky investments which result to higher returns. A stock is a certificate of ownership that shows partial ownership of a Company. Purchase of stock will make us part owner of the company. In investing in stocks we consider major factors to

PILOT STUDY PROTOCOL ON POLICY THAT PROMOTE OR FACILITATE OBESITY AND Coursework

PILOT STUDY PROTOCOL ON POLICY THAT PROMOTE OR FACILITATE OBESITY AND POVERTY WITH IT'S ASSOCIATED DISEASE DIABETES 2 - Coursework Example en poverty, obesity and diabetes 2; many of the people diagnosed with obesity and diabetes 2 are Native Americans, blacks and Hispanics, where rate of obesity reaches upto 70%, and this has been accredited to their deprived economic conditions. Obesity and diabetes are among the vigorously growing health problems faced by Americans. The prevalence in obesity rates has caused massive cases of diabetes 2 which in turn causes amputations, hypertension and blindness, and also increases chances of developing depression, cancer, heart disease, asthma, immobility and arthritis. Allowing the current rates of poverty and obesity to continue increasing implies that America will be trailing on a perilous track. Moreover, the obesity endemic, if left unimpeded, will contravene the substantial progress made in life expectancy and health in the recent decades (Klein et al., 2004). Certainly, if current and future generations are to live longer, healthy and exciting lives, this cosmic problem must be contained through effective policy formulation and implementation. Obesity costs the nation over $160 billion in direct therapeutic costs every year. Estimates indicate that yearly medical expenditures can be plummeted by between 7-12% if the government succeeds to eradicate obesity and diabetes 2 (Levine, 2011). Additionally, through Medicare and Medicaid, a substantial fraction of this cost is financed by assiduous taxpayers and this affects both federal and state budgets and significantly hinders meaningful economic development. It is too costly to overlook the skyrocketing premature deaths resulting from obesity and obesity-associated chronic diseases. Consequently, this pilot study seeks to explore the state government’s roles in regulating the two lethal epidemics. It will seek to explore whether the policies of developing EMR system that back diabetes prevention, guaranteeing parity of mental and physical health services, promoting active lifestyles, increasing Medicaid

Customer behaviour in charity retailing in UK Dissertation

Customer behaviour in charity retailing in UK - Dissertation Example Shopping in charity stores has seen a revived popularity with the emergence of the recession and the popularity of conservation style living. The reasons and drives that consumers feel to enter into thrift stores are varied and interesting as they reflect psychologies about the past as much as modern aesthetics. The emergence of the charity thrift store can be traced to the Salvation Army in London where the store was created in order to give some of those who were unemployed a job, the sale of the items supporting the wages for those collecting the goods. The desire for vintage style and the added bonus of conservation through repurposing has placed the charity store back into the lists of retail outlets being used by modern consumers. 1.2 Background With the emergence of the recession and the consequential focus on conservative spending, charity retailing has become a more significant resource from which to replenish needs and wants. Through items that have been donated by others for sales to benefit charities, revitalization can be found through new owners who can repurpose the items for their own uses. Changes in the retail environment are being reflected through the concept of repurposing. Green technologies and products that are designed for natural, organic, or socially responsible consumerism can be seen as examples of the type of retailing that is designed to provide a sustainable responsibility in consumer behaviour. ...

Green technologies and products that are designed for natural, organic, or socially responsible co nsumerism can be seen as examples of the type of retailing that is designed to provide a sustainable responsibility in consumer behaviour (Krafft and Mantrala 2010). Consumer behaviours have changed in the last five years as the economy has dived into a recessive cycle. How money is spent is much more closely guarded, thus creating a more conscientious consumer. Items that can be repurposed and given a new function within the hands of a new consumer provides a sense of fulfilment as consumers find themselves trying to find ways to make ends meet. In addition, the charitable concept of buying in a store that is designed to benefit those in need is appealing to the consumer as the trends have been seen to support the evolution of more responsible living.

China and Inexperienced Industrial Revolution Essay - 1

China and Inexperienced Industrial Revolution - Essay Example Coal was at the time a better form of heat production. It gave constant, reliable amount of heat without giving out a lot of by-products as a waste (McCloskey 2010). The changeover was due to great innovation from individuals and group of people who skilfully devised ways to make work easier and create a better life for everyone (Chai 2011). Most of the innovations were involuntary and automatic, but additionally, there were others that founded through a series of experiments and exploit of science (Duiker and   Spielvogel 2011). This revolution, that is an industry based, commenced in Britain and a few years later it stretched to the United States of America, as well as Western Europe (Chai 2011). It grades one of the most significant turning points in the account of the history of the whole world. Nearly all aspects of the everyday life of the inhabitants of the planet were greatly influenced in one way or another (Nolan 2008). The thing that was mostly experienced was the sharp growth of the human population. The society at this period was exceedingly rural in nature. The revolution changed this to a much modern and urban society for most of the nations at that time (Beele 2002). Many countries experienced this mode of change that spread from the center of origin in Britain. China has had a dynamic economy in terms of its economy in the recent years (Nolan 2008). But why did it delay in achieving better industrialization that other states in Europe and other countries in the regions of the world were developing in the period? This paper is going to assess the reasons why China did not experience ‘industrial revolution’ between c. 1700 and 1949. According to Bayo r (2011), there was a delay in the industrialization in China until later in the century. In order to curb these problems, the country decided to raise its investment significantly together with the signing of a huge number of deals that included overseas companies that offered their services in the construction of some of the chief amenities for compound fertilizer manufacture, steel production and oil mining and processing in the refinery plant.These factors - availability of raw materials in Europe, a lot of richness acquired from the colonies, the widespread trade around the world, the presence of a unwavering form of government that offered support to the effectiveness of real establishments and was optimistic in scientific progress - made the European countries gain an upper advantage in revolutionising earlier in the century. China was not able to compete with these countries owing to the conditions which it was in that period.

Vesta, The Roman Goddess of Heart and Fire Essay Example for Free

Vesta, The Roman Goddess of Heart and Fire Essay Vesta is the Goddess of Heart and Fire. Being one of the most popular gods/goddesses of Ancient Rome, she symbolizes â€Å"the continuity of the life of the State† (Johnston, par. 488). Being a people of deep religious feeling (Hamilton 45), the ancient Romans embraced gods and goddesses like Vesta into their everyday lives, as they gained in statute and dignity before the eyes of gods and men. Every ancient Roman family has the personification of Vesta in their home, as she is one of the family’s own gods and goddesses. Vesta is among the gods/goddesses who were â€Å"never worshipped in temples, but only in the home, where some of the food at each meal was offered to them† (Hamilton 45). For this reason, Vesta appears to be one of the most lived gods and goddesses of Rome, protecting the heart of the family in order to gain stability, prestige, and dignity. This paper revolves around Vesta, the Roman Goddess of Heart and Fire, and how the Vestal Virgins appear and relate to the ancient Roman state. After examining the dense issue of how Vesta and the Vestal Virgins appear and relate to the people, it shall be proposed that the appointing of Vestal Virgins do not indicate Ancient Rome’s affinity or high respect with the females in general. Instead, it proposes that females can have an opportunity of having the highest honor within the community if she is true to her duties and her chastity. This proposition is supported by the idea that: first, Vestal Virgins carry one of the heaviest responsibilities associated with their social position, and if they are true to it, then they get one of the highest honors; second, Vestal Virgins carry one of the heaviest sacrifices associated with their social position, and if they are true to it, then they get one of the highest honors; third, Vestal Virgins carry one of the heaviest punishments associated with their social position, but if they are true to it, then they get one of the highest honors. Main Text Vestal Virgins Carry One of the Heaviest Responsibilities Vestal Virgins were associated to possess strong spirits and powers in the ancient state of Rome. As priestess of the goddess Vesta, they carry one of the heaviest responsibilities, as they keep the ‘sacred fire’ in the altar aflame and lingering. As stated in the recent page, this act symbolizes â€Å"the continuity of life of the State† (Johnston, par. 488), and this makes it very necessary for the state and the village. Having to protect the ‘home fires’ of the people, Vestal Virgins keep homes stable and flourishing as well, as daughters of the households assist them in tending fires, and then gain stability and permanence. In the process, the virgins would have to be of noble origin. The College of the Vestal Virgins is composed of 18 members, with 6 members working at a time (Fowler, par. 3). Originally, only the upper class blood were traditionally allowed to be included in the college, but later on, it was approved that daughters of patriarchs and freedman were allowed to join the college (Fowler, par. 3). Handpicking physically ideal girls who were 6-10 years of age and had two living parents (Fowler, par. 3), they were sworn to celibacy to serve the first ten years of their Vestal life learning priesthood, the next ten years applying what they learned of priesthood, and the last ten years of priesthood teaching to the new Vestal Virgins what they have learned. Vesta and her Vestal Virgins carry the crucial role of keeping the family and state intact and thriving, though in a metaphorical way. Vestal Virgins Carry One of the Heaviest Sacrifices Vestal Virgins carry one of the heaviest sacrifices in the ancient state of Rome, as they lived their whole lives in total celibacy, chastity and purity. At the end of their term—which is exactly 30 years—these women were allowed to get married. However, as stated by Fowler (2006), â€Å"[m]any retired Vestals decided against marriage† (par. 4). This is because, according to the Roman tradition, wives were supposed to be under the dominion of their husbands. Having to live almost all of their lives getting prime seats in Roman theaters, attending luxurious dinners and parties, or having the permission to vote†¦ being under the power of a man would be very difficult; thus, they spend the rest of their lives being single. Another significant responsibility of Vestal Virgins appears during the celebration of Vesta—the feast called ‘Vestalia’, which is an â€Å"annual ritual in honor of their patron goddess, Vesta† (Fowler, par. 6). As stated by Fowler (2006), every June 7-15 of the year†¦ â€Å"[T]he doors of the Temple of Vesta opened to the mothers of the families of Rome who brought offerings of food to the goddess. The Virgins also prepared special food offerings at this time. This occasion was the only time of year that the doors of the temple were opened to the public. † (par. 6) In vowing for a powerful position for women in the Ancient Rome, such as being a Vestal Virgin, the religious and political rank carried with it heavy sacrifices and forfeits. Vestal Virgins Carry One of the Heaviest Punishments Lastly, Vestal Virgins carry one of the heaviest punishments in Ancient Rome. Aside from the forfeit and sacrifices that were mentioned above, the virgins carry a chastisement if they failed to comply with their responsibilities in keeping the fire of the family and state aflame. This spells death and disaster when the member breaks the vow of celibacy, with the execution being given by means of the following strategies: first, by being buried alive; second, by being thrown into the Tibet River; third, by being publicly whipped (Fowler, par. 5). Aside from her failure to keep her celibacy and chastity, another grave destruction for a Vestal Virgin is when she fails to keep the ceremonial fire inside the Temple of Vesta. It is, indeed, an appealing way of life, as dictated by Fowler (2006, par. 4)†¦ but the responsibilities are grave and the punishments are nothing but life threatening. Conclusion Vesta and her Vestal Virgins relates and serves to the families and state of Rome by doing the following: first, by keeping the sacred fire aflame and burning; second, by keeping the home fires stable and flourishing; third, by sacrificing to a life of chastity and celibacy; fourth and final, by keeping the feast of Vestalia alive within the state. However, as the life of Vestal Virgins reflect one that is full of responsibilities, sacrifices, and punishments†¦ it is evident that the appointing of Vestal Virgins does not indicate Ancient Rome’s affinity or high respect with the females in general. Instead, it proposes that females were given the chance to live a life that only the males were given privilege in the ancient world. If she remains true to her word, her chastity, and her responsibility, then she gains all the respect, dignity and power that only a few citizens were able to obtain. It is true that ancient women of Rome were more privileged in 700 B. C. , but still, life and existence are always at stake. It was 37 years after the founding of Rome that Romulus—one of its founders—was said to have disappeared in a thunderstorm (Bingley, par. 1). Having no king, Numa Pompilius was elected as king of the state, who then appointed priests, pontifices, flamines, the Salii†¦ and the Vestal Virgins who, since then, took charge of fire and water (Dio 3).

Advantages and disadvantages of Specialisation

Advantages and disadvantages of Specialisation Introduction International trade and Foreign Direct Investment (FDI) equity flows are the two primary methods in which international business occurs and are amongst the most substantial drivers of present time globalisation. With consecutive rounds of multilateral dialogues at the World Trade Organisation (WTO), barriers to trade globally, have been done away with significantly. Likewise, the relaxation and liberalisation of developed countries capital markets during the 1980s has brought about a brand-new age of global capital mobility whereby Foreign Direct Investment is a primary and vital facet to trade globally. Both experiential and theoretical frameworks have incidentally thrived to explicate and predict these patterns in international business, as well as the determinatives and affects of International Trade and FDI flows for both the host and home countries. International Trade is the exchange of capital, goods, and services across international borders or territories (dictionary.reference.com). FDI Foreign direct investment refers to the long-term engagement of a nation A into nation B for example. It normally requires involvement in expertise, know-how, joint-venture, management and transfer of technology, etc. There are two forms of Foreign Direct Investment: inbound FDI and outbound FDI, bringing about either a positive or negative net FDI inflow and stock of FDI equities, which is the total figure for a given period of time. It is important to note, however, that direct investment does not include investments made by means of purchasing shares. Specialisation Specialisation is the focus of labour in specified, limited duties and functions. It is the name ascribed to the prevalent system of economic consumption, production, and interlinked socio-economic progression and processes, in most industrialised nations ever since the late twentieth century. In fact, trade exists as a result of specialisation and the division of labour, where most workers focus on a limited facet of production and trading, during the process, for different trade goods. Trade exists between various nations and trading blocs because different industries in diverse countries and regions globally have a comparative advantage in the manufacturing/production of certain tradable commodities/goods, or because different countries sizes permit for the benefits of mass production. Intrinsically, trade at market prices amongst different countries/regions benefits both partners involved in the trade exchange. International Trade Theory Adam Smith (1723-1790) was a prominent Scottish economist and political thinker whose famed work Wealth of Nations (1776) set the pitch for work on economics and politics for many individuals and institutions even today. This was, as a matter of fact, the first extensive attempt to examine the nature of capital, the development of industry and the effects of large-scale commerce in Europe. Adam Smiths fundamental argumentation was that people should be free and able to engage in their own private economic interests as much as possible just as long as they do not break the rudimentary rules of justice. In this manner, Smith believed, they would do far more good to advance and promote the publics welfare and interests, more than if the same people were to attempt to assist the public on purpose. Smith named this the invisible hand of the market, though everyone is performing in their own self-interest, they are led to accomplish the good for all like an invisible hand of economic powers. Hence, outside intervention will unavoidably induce calamity. This later became renowned as laissez faire economic policy (economyprofessor.com). Adam Smith (Wealth of Nations) reasoned that economic specialisation could be beneficial to countries as to corporations, back in 1776. Due to the division of labour being limited by the market size, he argued that nations with access to bigger markets will be capable of splitting labour more productively and hence become more efficient in the long run. Smith however, failed to realise that the division of labour is also intrinsically limited by the technology in production coordination (Yu, Zhihao, 2005). The theory of Absolute Advantage was introduced Adam Smith and is apparent between trade counterparts when a country is able to produce more of a commodity/product, with the same resources, than its partner can; it is therefore said to hold a position of Absolute Advantage in the production of that end product. If, however, the other country has an Absolute Advantage in producing a commodity/product that the its partner needs, each will be fortunate if they specialise and trade. Trade is normally mutually advantageous even if one country holds an absolute advantage over its partner country, in the production of both goods being traded. The Heckscher-Ohlin (HO) model was first formed by Eli Heckscher (1919) and Bertil Ohlin, two Swedish economists. Elis Heckschers own student, Bertil Ohlin formulated and detailed the Factor Endowment Theory. He was not just a economics professor in Stockholm, but also a leading political figure in Sweden at the time. Fundamental concepts were further formulated and added subsequently by Ronald Jones and Paul Samuelson amongst others. Due to the difficulty of forecasting the trade of goods pattern in a globe with an abundance of goods, as an alternative to the Heckscher-Ohlin Model, the Heckscher-Ohlin-Vanek Theorem that prognosticates the factor capacity of trade has acquired attention in recent years (econ.iastate.edu). The Heckscher-Ohlin Model explicated that countries of the same factor endowments would still trade due to the differences in technology, as this would induce specialisation and thus trade, in precisely the same manner as in the Ricardian Model. Another theory that attempts to predict the patterns of trade is that of the Law of Comparative Advantage (David Ricardo) in the goods with the lower opportunity cost. David Ricardo (1772-1823), during the early 19th century, saw that the theory of Absolute Advantage was a moderate and restricted instance of a more dynamically broad theory. Ricardo, in essence, was sort of a replacement and continuation to Adam Smiths prominent position in British economics. His work went on to shape and influence the aims and methods of the discipline all through the nineteenth century. In spite of his personal substantial work experience, his written material can sometimes come across as being very abstract and often hard to understand. His main stress was on the principles of diminishing returns linked to land rental, which he thought also regulated capital profits. He tried to derive a theory of value from labour application, but found it hard to separate the effects of changes in technology from changes in distribution. The scarceness of natural resources globally, one of the more fundamental concepts of economics, requires that there be tradeoffs, and these tradeoffs lead to an opportunity cost. Whilst the price of a good or service is often-times thought of in terms of currency, the opportunity cost of taking a decision is based on what good or service must be forgone, which would be the next best option, as a consequence of taking the decision. Decisions that require having to choose between two or more options are said to have an opportunity cost. The Law of Comparative Advantage explicates how nations can take advantage of and exploit specialisation and trade. Given any two goods/commodities, the nation manufacturing the good/commodity with the lower opportunity cost is said to have a comparative advantage. In simple terms, it is the capability of a nation to produce a product at a lower cost than others can produce it. Specialising provides that nation with a comparative advantage vis-Ã  -vis other trade players. The basis of trade activities must be directed in a way where each country cuts the opportunity costs of the goods being swapped in their trade exchanges. Heckscher and Ohlins theory, adapted from Ricardos comparative advantage model, suggested that different costs were the result not only of dissimilar labour endowments between countries, but also of different capital and land endowments. For example, a country like Saudi Arabia is much more amply endowed with oil than say France. France, on the other hand, has a rich abundance of skilled labour and capital equipment in the defence industry. Hence the theory would suggest that Saudi Arabia would specialise in producing oil, France in producing defence equipment and that the two countries will trade one product for the other (Anderton, Alain, 2004). Advantages of International Trade and Specialisation Some advantages of International Trade include monetary benefits to the respective countries participating in trade, it can also improve relations between countries and allow for a great cultural exchange. It also allows for more of a choice and assortments of goods that are affordable (value for money) and readily acquirable for consumers, better quality goods, enhanced and increased competition both at the global and national level, closer links and affiliations amongst countries globally, more of an exchange of technical expertise, technology and synergistic know-how, producers locally will endeavour to better the quality of their products, as well as an increase in employment nationally. In the same way domestic trade encourages economic development and prosperity, so does International Trade. International commerce gives rise to specialisation, where a producer produces the good at the lowest cost of opportunity and production to them and thereafter trades for goods that are produced at a higher opportunity or production to them. Not only does International Trade lead to shared benefits by permitting various nations to specialise their industries of those products/commodities they produce at top-quality, but it also lets them import products that international producers are inclined to provide at a lower cost than national producers are willing. Resources do vary between nations and provide certain nations with an advantage of producing certain goods over other ones and turn out to be more profit-making and beneficial to all. By permitting for International Trade, nations can specialise in those products that they can produce efficiently and at the lowest cost and then supply them to consumers at a low-cost, more inexpensive, and more economic price. Additionally, by importing those products from other nations and then exporting goods to those nations, both partners, involved in the trade exchange, benefit in a win-win state of affairs. It is crucial to take note, however, the case of absolute advantage. As mentioned before, absolute advantage is a scenario where a country, due to its natural endowments and or prior experiences, can manufacture more of a product/commodity, with the same quantity of resources, than another country can. However, this does not imply that only because one country has an absolute advantage, the countries trading with this nation will not benefit from the trade. Yes, they still can benefit, in point of fact, that is, conditional upon the relative production costs varying. Advantages of specialisation include increasing rewards and profit returns due to economies of scale, gains from exploiting an absolute or comparative advantage, through which specialisation is explained, more efficiency and productivity as well as focus for producers, less cost to the producer as well as the consumer, better quality end products and a wider range of choice for the consumer, and last but not least, through specialisation in production, countries can increase their income, as well as expand and develop their economies. A strong argument put forward in favour of the concept of free trade would be that it is rather clear and apparent that free trade is beneficial to all partners involved. It helps nations attain a comparative advantage and corporations/industries to focus on specialisation, both of which result in economic benefits, growth, and prosperity. Furthermore, these two concept are big revolutionary contributors to the sophisticated and progressive state of the globes nations in the present time. Without them, we would be decades behind in various ways, particularly from a technological standpoint. Participating in these activities proves beneficial for all trade partners and results in economic prosperity and wealth, therefore, improving peoples standards of living (Rose, Phantom, 2009). Disadvantages of International Trade and Specialisation Some disadvantages of trade include a heavy reliance on a particular nation, national production may also be hindered as national industries may be excelled and eclipsed by their international competitors, affluent nations may have more powers in influencing political issues in other nations and acquire control over weaker ones, and what is more, ideological clashes may come about amongst trading partner countries regarding the processes in trade activities for example. Specialisation in itself, however, can hinder trade. For example, if a nation is too reliant on one specific industry and the prices dip in that industry, then unemployment will take place dramatically. This is an occurrence in several developing nations and is also applicable, for example, to the West Midlands, UK, a region that is heavily reliant on the auto industry. Factors of productions cannot be easily shifted from one area to another, this is known as factor immobility. For instance, if after International Trade, country/company A would diminish the production of product B, then the labour producing product B cannot easily be shifted and re-trained to produce an additional product C, therefore, unemployment will take place. International trade can also pose as a harm to birth industries in the home nation as well, due to their production costs being high in the infant, early stages. Over-specialisation may have devastating effects if, for example, a war breaks out in a country and imports/exports cease. Therefore, the nation never specialises wholly due to political/strategic factors. In addition, if imports exceed exports, the balance of trade payments would be in the red (negative territory), which, in turn, will harm the home countrys economy and may also result in the devaluation of its currency.

The Law Of Evidence

The Law Of Evidence Smooth muscle is one of three muscle fiber types found in animals. Unlike skeletal and cardiac muscle cells, smooth muscle cells are not striated, and have single nuclei. Smooth muscles are typically under control of the autonomic nervous system, and do not contract voluntarily. Smooth muscle contracts slowly, and does not exhibit the characteristic twitch seen in skeletal muscle. In addition, smooth muscle is not prone to muscle fatigue, making it an ideal component of sphincter muscles. Smooth muscle is found in the gastrointestinal tract of many animals, and is responsible for peristaltic movements. Smooth muscle contractions are affected by calcium and potassium ions. Calcium ion influx into the smooth muscle cell initiates a contraction. Potassium ion concentration in the extra cellular medium affects the resting membrane potential of the cell, bringing it closer to or farther away from its threshold voltage. Neurotransmitters affect different types of smooth muscle differently, depending on the association of the smooth muscle with excitable cells. In general, acetylcholine increases the muscle cells permeability to calcium, while epinephrine decreases the cells permeability to calcium. Introduction and aim of the experiment The following report was to test a smooth muscle which was collected from the intestine of a rabbit. The main of this experiment was to see how the surrounding environment of the muscle could affect how muscle contracted. The experiment consisted of different environments and the muscle was monitored and results were recorded of the amplitude and the frequency of the wavelengths. The levels of muscle contractions and relaxations were measured using a transducer, a D.C amplifier, and a laboratory computer. Overview of experiment The smooth muscle was a small part of the intestine which was prepared correctly by trimming off the attached mesentery and fat. This experiment only required one piece of this smooth muscle and this was then placed into a beaker which was aerated and fed Ringer-Locke solution this is an aqueous solution containing the chlorides of sodium and potassium and calcium that is isotonic to animal tissues. The experiment only required one piece of small intestine, which had the length of 2-3 cm long. The intestine was held in place with a tissue holder, and was attached to the transducer via a piece of string. The transducer detected contractions and relaxation of the muscle, and via the D.C amplifier showed on the computer the frequency and strength of the contractions and relaxations. The solution that the muscle was placed in was kept at the temperature of 37 Celsius apart from when the environment condition changed was the temperature. This type of setup is known as in vivo preparation. This preparation of the smooth intestine allows a precise control of the environmental conditions. Brief description of test carried out The test which was carried out had six parts to it. The first part of the experiment was to gain initial control of the muscle this was done by having optimum conditions for the smooth muscle so it could achieve a steady rate of contraction and relaxation. This was achieved by adding Ringer-Locke solution and keeping it aerated. By having this set up it allowed the muscle environment to be very closely met to the ideal body environment where the muscle would have a good contraction and relaxation rate. The muscle was left in this preparation until the readings on the computer were constant (about 4 minutes) the initial control was labelled using the comment bar. The next environment was non-aerated this meant to turn the air supply off which was coming to the bath where the muscle was held. Then the Ringer-Locke solution was removed from the bath and fresh Ringer-Locke solution was then placed into the bath. The reason for removing the old solution was to prevent any inaccurate readings as the solution could still have contained oxygen which would have affected the results. This part of the test was recorded after every 5, 10, 15 minutes and the results where inserted into a table. The main purpose of using this environment was to see what the muscle contractions and relaxations are when there is a lack of oxygen. This part of the experiment was again labelled on the comment bar. The next part of the experiment was to remove the Ringer-Locke solution and replace it with 50ml of glucose free solution and again results were recorded after every 5 ,10, 15 minutes and recorded into a table. The fourth different environment was change in temperature. The Ringer-Locke solution of 37 Celsius was replaced with a Ringer-Locke solution that was cooled to 4 Celsius. The purpose of this environment was to test the muscle activity in a cold environment and to analyse the effects. The fifth environment involved the use of calcium free solution this replaced the Ringer-Locke solution. This was analysed for 5 minutes to see how the muscle activity was affected. The final environment was to do with changes in the pH. The pH was changed from pH7 which is neutral to a different pH. The solution with different pH was prepared before hand and the purpose of this environment was to see what effect a pH change would have on the muscle activity. After each part of the experiment initial control was established before moving on to the next part the reason for this being to keep the muscle running properly before each part of the experiment and to cause less damage to the smooth muscle. Also each part of the experiment was labelled on the comment bar this was done to show each different part clearly so it was not confused. (Clear methods are shown in the printouts) Results table for my experiment Firstly the results achieved ere done by looking at the different graphs and to work out the amplitude for the graph the following was done: Example (Graph not related to report) To work out the amplitude of the graph recording two figures were recorded one being the peak of the wave and the other being the lowest part of the wave To work out the frequency for each part of the experiment the amount of waves were recorded in a minute time period. The frequency in this case was how many times the muscles contracted and relaxed in a minutes. The amplitude was the strength of each contraction and relaxing of the muscle. The maximum and minimum amplitudes were collected for each environment and recorded; the amplitude chosen was picked at random as well as the minute where the frequency of waves was calculated. These are results are shown in the table below: Environments Frequency per Minute (min-1) Amplitude 1 Amplitude 2 Maximum Minimum Maximum Minimum Initial control 15 2.10 0.78 1.96 0.65 Non aerated 5 Mins 13 1.94 0.47 1.89 0.38 Non aerated 10 Mins 17 1.53 0.36 1.51 0.38 Non aerated 15 Mins 16 1.58 0.38 1.54 0.36 Lack of glucose 5 mins 17 1.34 0.47 1.49 0.41 Lack of glucose 10 mins 17 1.51 0.43 1.52 0.45 Lack of glucose 15 mins 17 1.37 0.45 1.43 0.46 Cold ringer solution 5 Mins 14 1.76 0.44 1.73 0.51 Calcium Lack 5 Mins 12 1.15 0.63 .95 0.47 Change of pH Flat No waves Discussion of results Firstly a diagram of the intestine is needed to show how it works and what different types of cells it contains. This is needed as it will help to understand why the muscle behaved differently when tested with six different environments. A diagram of the small intestine is shown below; The small intestine contains the 4 basic layers which are serosa, muscularis, submucosa, and mucosa. Small intestine wall is composed of the same four layers that make up most of the gastrointestinal tract: serosa, muscularis, submucosa, and mucosa. The mucosa is composed of a layer of epithelium, lamina propria, and muscularis mucosae. The epithelial layer of the small intestinal musoca consists of simple columnar epithelium that contains many types of cells. Some of these are the following: Enetrocytes these help with the transport of substances from lumen of the intestine to the circulatory system, synthesis of the glycoprotein enzymes needed for terminal digestion and absorption. Goblet cells these are unicellular mucin also known as secreting glands. Paneth cells these are located at the bottom of the intestinal glands. Their main function is their secretion of granules which contain lysozyme this enzyme helps breakdown bacteria also known as phagocytosis. Paneth cells may have a role in regulating the microbial population in the small intestine. Enteroendocrine cells these are mostly found again in the lower parts of the intestinal gland known as the crypt. The main function of these cells is to release several hormones. The main one beings cholecystokinin, secretin and gastric inhibitory peptide these help increase pancreatic and gallbladder activity. Intermediate cells these are young enterocytes and goblet cell which are able to withstand cell division. Apart from the smooth muscle many other cells and vessels make up the intestine. The small intestine also contains submucosal artery and vein, lymphatic vessel, submucosal plexus, circular layer of smooth muscle, and myenteric plexus. All these tissues, cells, and vessel combine to make the small intestine wall. The smooth muscle in the control environment was able to obtain a steady frequency through out its 4 minute period with 15 waves per minute. The waves which were seen were the smooth muscle contracting and relaxing. The amplitude levels of the waves were both quite high showing strong contractions rate the reason for this was that the environment set was to ideal conditions where the muscle could perform its best. It had a max amplitude of 2.10 and min amplitude of 0.78 which shows that having ideal conditions the muscle is able to behave normally without any problems. The effect of oxygen lack of the smooth muscle cause the small intestine to increase the frequency, at 5 minutes no aerated the frequency had first dropped to 13 and after 15 minutes the frequency of contraction and relaxations had increased to 17 the reason or this being without oxygen the smooth muscles started to have spasms as it was unable to contract properly without the oxygen supply needed. Also the amplitude levels decreased quite quickly from 1.94 (max) and 0.47(min) at 5 minutes to 1.58(max) and 0.38 (min) at 15 minutes. The reason for this was that without oxygen the muscle was unable to make the energy needed for strong contractions as the peak is lowered as can be seen on the traces. This was detected by the pull on the string that was attached to the transducer; the pull was not as strong so this was recorded on the traces. So without oxygen the muscle cells are still able to make ATP but a small amount. Only about 2 ATP are produced per molecule of glucose in glycolys is. If there is no oxygen present, the Pyruvate produced in glycolysis undergoes fermentation to regenerate the NAD+ used in glycolysis. This is known as anaerobic respiration, anaerobic respiration generates only two ATPs, and lactic acid is produced. Most lactic acid diffuses out of the cell and into the bloodstream and is subsequently absorbed by the liver. Some of the lactic acid remains in the muscle fibers, where it contributes to muscle fatigue. Because both the liver and muscle fibers must convert the lactic acid back to pyruvic acid when oxygen becomes available, anaerobic respiration is said to produce oxygen debt The next part of the experiment was to test how the muscle activity differed when placed in glucose free solution. From this part of the test the frequency of muscle activity stayed consistent throughout the 15 minutes. The traces show consistent movement and also the amplitudes levels differed as at 5 minutes (1.34) the maximum amplitude was low then at 10 minutes (1.51) it wet higher and at 15 minutes (1.37) it decreased again to a similar figure which was at 5 minutes. By looking at this result the results are not as accurate as they should have been, meaning they may have been some kind of inaccuracy when following the method as without glucose, ATP can not be made and the amplitude of the waves should have been lower. ATP can be made from glucose which is stored in the carbohydrate glycogen. Through the metabolic process of glycogenolysis, glycogen is broken down to release glucose. ATP is then generated from glucose by cellular respiration. Also ATP can be produced from glucose and fatty acids obtained from the bloodstream. When energy requirements are high, glucose from glycogen stored in the liver and fatty acids from fat stored in adipose cells and the liver are released into the bloodstream. Glucose and fatty acids are then absorbed from the bloodstream by muscle cells. ATP is then generated from these energy-rich molecules by cellular respiration. Without glucose the frequecny should hve increased but the amplitudes levels should have decreased as there was not a sufficient energy source which could supply the muscle so it could contract and relax. The next part of the experiment consisted of placing the smooth muscle into a cooled solution of 4 Celsius from a change of 37 Celsius. There was not much change to the frequency but it did drop a little bit due to the muscle not being used to these environmental conditions. The amplitude differed from the control readings as they had decreased but were still quite high as they had the nutrients in the solutions which helped them to contract. If this experiment was left to carry on then there would be further change as the solution would gradually heat up to room temperature and this would mean that the smooth muscle activity would increase. Calcium plays a big part in all muscle contraction as well as smooth muscle contraction which is different as it does not contain troponin. In smooth muscles calcium ions enter from outside the cell. They then bind to an enzyme complex on myosin; this then breaks up ATP into ADP and then transfers the Pi directly into myosin. By doing this it allows the myosin to activate and from cross ridges with actin. When the calcium is pumped out of the cell, the Pi gets removed from myosin by an enzyme this allows the myosin to become inactive and the smooth muscle is able to relax. This process is also known as myosin regulated contraction. In the experiment where calcium free solution was added it affected the smooth muscle immensely as the frequency of contracting and relaxing dropped to 12. Also the amplitude levels came down as the contractions and relaxations levels were not strong the max being 0.95 and the minimum being 0.47 if this was left for a longer period of time the frequency levels may have dropped more. Without calcium entering the cell the smooth muscle is unable to do the process which is described above. While making the Ringer-Locke solution it is not only the calcium ions which are important to the smooth muscles. Some others are potassium chloride and sodium chloride, the reason these ions are needed because it helps to portray an environment such as the body with ideal conditions. If only distilled water was used it would mean the cells in the muscles would up take the water and blow up. So these ions are used so they are able to keep a concentration gradient and allow everything to work correctly as it would in the smooth muscles natural environment. The final environment was the change in pH levels. The results showed that the muscle had stopped functioning and there was no reading on the traces. This meant that there was no muscle contraction or relaxing. The reason for this was the muscle had broken down the reason for this muscle fatigue was that the low pH had affected the smooth muscle as it was unable to perform in this type of environment. Also as the low pH solution was there for a certain period of time the muscle was unable to remove it and therefore caused the muscle to breakdown. The low pH may have affected the sarcoplasmic reticulum which may lead to the interfere of the intercellular calcium concentrations, this can lead to long term physical muscle damage as muscle fibers are affected. While preparing the isolated smooth muscle many precautions are taken so the muscle can avoid excessive pH changes. One of these precautions which are taken is to make sure that before inserting the small intestine into the bath. The solution will need to be tested with pH indicator test strips which will give a fairly accurate reading of the solution which the smooth muscle will be placed. This is very important as if the pH is incorrect it will mean that the smooth muscle will not perform to its full potential meaning the results achieved will be inaccurate. To gain accurate results all solutions which are used will need to be checked to see if they are the correct pH by using the ph indicating strips. After this test the smooth muscle was unable to reach the control again as the muscle had broken down. If this experiment was done again at room temperature the results would differ as the performance of the muscle would decrease. This is because the optimum temperature inside the body is around 37 Celsius and this temperature allows the muscle to work at an optimum rate. The lower temperature will mean that muscle contraction will be slower as there will be an effect on enzyme reactions as the more heat there is the more kinetic energy there is this will mean that the muscle activity will be good. If acetylcholine was added to the solution bath of the smooth muscle the membrane potential would decrease and the frequency of waves would increase. The muscle will become more active, with an increase in tonic tension and the number of rhythmic contractions. The effect is mediated by enzymes which increases the intracellular Calcium concentration. Another substance which could have been added was adrenaline. Adrenaline allows blood to flow more easily to your muscles. This means that more oxygen is carried to your muscles by the extra blood, which allows your muscles to function at elevated levels. Adrenaline also facilitates the conversion of the bodys fuel source (glycogen) into its fuel (glucose). This carbohydrate gives energy to muscles, and a sudden burst of glucose also allows muscles to strengthen further. Skeletal and smooth muscle muscles differences in structure and function There are many differences between the two types of muscles the differences are stated below: Snmooth muscles Skeletal muscle A smooth muscle fiber has no T tubules, and the sarcoplasmic reticulum forms a loose network throughout the sarcoplasm. Are long cyrindrical cells that contain many nuclei Smooth muscle tissue has no myofibrils or sarcomeres They are striated this shows their precise alignments of their myofilaments. This tissue also has no striations and is called nonstriated muscle. Thick filaments consist of myosin as thin filaments consist mostly of actin. Thick filaments are scattered throughout the sarcoplasm of a smooth muscle cell Each independent cell is stimulated by a motor neurone. Adjacent smooth muscle cells are bound together at dense bodies, transmitting the contractile forces from cell to cell throughout the tissue. Connective endomysium seprates cell Function Differences Smooth muscles cells are an involuntary action and can work slower so they do not have muscle fatigue. Skeletal Muscle contains both Fast Slow Twitch muscle fibers, that allow for a faster reaction where needed, and the opposite is true for the Slow as well Smooth muscle lines your arteries and airways and serves to contract or relax to help control blood pressure. skeletal muscles function almost continuously to maintain your posture making one tiny adjustment after another to keep your body upright They are also present in the iris of the eye to control the size of the pupil in response to light. By the use of the radial and circular muscle. Skeletal muscle is also important for holding your bones in the correct position and prevents your joints from dislocating. Some skeletal muscles in your face are directly attached to your skin They line the GI tract to move foodthrough the intestines. This is done by peristalsis. Skeletal muscle generates heat as a by-product of muscle activity. This heat is vital for maintaining your normal body temperature.
