How Many Of You Grew Up From A Different Country

COMING TO A NEW COUNTRY WITH A CULTURE SHOCK- A PERSONAL STORY ï‡ ºÃ¯â€¡ ¸Ã¯â€¡ «Ã¯â€¡ · How many of you grew up in a different country, a different continent? Australia? Poland? China? Africa? or perhaps in Argentina? It does not matter where you were born or raised, it’s about the feeling you have to experience when you arrive in a whole new place. It is, indeed, an amazing, challenging journey full of new experiences. Simple cannot be the word to describe how the feeling approaches a person arriving in a new place. The feeling that consumes a person who is entering a different culture can be terrifying at first.

This Brief Essay Studied The Uninsured And The Health Care

This brief essay studied the uninsured and the health care disparities they face. Essential Affordable Care Act provisions and their effects were studied. Critical factors affecting the health care of the uninsured were identified; these included race, ethnicity, income, socioeconomic status, culture, language and income. Several research studies concluded that while access to health care has improved, the quality of this care has not improved for the uninsured. Although the number of uninsured has been reduced dramatically since 2010, insurance costs continue to increase significantly. Failure of states to expand Medicaid benefits has limited uninsured patients’ health care options. Free health clinics often handle health care needs of†¦show more content†¦Although several provisions of the ACA are welcomed, the survey found most objected to requiring Americans to have health insurance of any kind (Alonso-Zaldivar, R. Swanson, E. (2017). Those who are uninsured and have limited financial resources are especially vulnerable. Unfortunately, data on the affordability of quality health care are limited (â€Å"2015 national healthcare,† 2016). The uninsured face severe health care disparities based on several factors that impact their lives and the quality and availability of the health care they receive. Factors Influencing This Issue The uninsured are often also members of specific ethnic and cultural populations. Race, ethnicity, income and socioeconomic status generally are considered interrelated factors. These interlaced influences are explored in this essay to underscore the links between the uninsured and other factors that impact their health care options. Mitchell (2015) discovered that, compared to white Americans, those who are uninsured or underinsured tend to lack regular sources and access to care and receive poor quality of care. About 50% of these individuals are â€Å"in lower socioeconomic brackets [with] limited education in historically underrepresented racial and ethnic groups, who have . . . experienced oppression, discrimination, and social and economic inequalities.

Alternative fuel technologies Free Essays

Oil and petroleum products have been mainstay of world’s economic and technological advancement since past 150 years. The mechanism driving the entire transportation system from automobiles, airplanes, railways, ships to space rockets is based on utilization of energy of petroleum oil. Petroleum products are also extensively used in a number of infrastructure industries that form the core of industrial processes and basis of existence of modern world. We will write a custom essay sample on Alternative fuel technologies or any similar topic only for you Order Now However, the petroleum resources of world are very limited and they cannot endlessly meet human demands. Various estimates have put the total extractable oil stock to exist for another 50-75 years if world continues to consume them at present rate. After that the cost of extraction of remaining petroleum products would become much more than the benefits obtained them and world would require new resources of energy to exist. These concerns have already spawned intense research in alternative technologies to meet the future energy needs in the face of an impending petroleum crisis. The shortage of oil would be more manifest in coming times as oil demands are growing world wide, especially in China and India with rapidly expanding economy, transportation system and consequently requirement of petroleum oil. Even at present consumption rate there are grave uncertainties on the secure prospects of future supplies within next 50 years time frame, and the rising consumption rates threatens to bring the approaching crisis nearer. United States is thus faced with a great responsibility to secure its future interests without sacrificing its present requirements and needs. This issue forms the topic of the next section. Alternative fuel technologies Past decade has seen great thrust on technological researches in alternative fuels. Various new techniques and models have already been introduced in the market to test their viability and capacity to successfully replace petroleum as chief source of energy. Most of these innovations are specifically aimed at transportation sector owing to its liability as chief consumer of petroleum oil and as principle cause of soaring oil imports. Due to distinct requirements of different sectors in transportation, the technologies vary. Passenger vehicles, public transport vehicles and freight transportation carry specific needs that are difficult to be met by a single alternative fuel technology (Deutch J, Schlesinger J. R, Victor D. G. 2006). Some of the major and most popular of these technologies, where majority of research and development has taken place, are (Aldrich, 1996) 1. Hybrid Vehicle: As the name suggests, hybrid vehicles combine dual technologies for their operation. Technically they are hybrid electric vehicle with an electric motor that drives the vehicle (Hoogma, Kemp, Schot and Truffer, 2002, 41 ). 2. Bio-diesels: Bio-diesel: Bio-diesel, as the term suggests, is a type of renewable fuel obtained by agricultural products and used as fuel in heavy-duty vehicles. The major sources currently under research for bio-diesel are soybean, rapeseed, corn, cottonseed, peanut, sunflower, and canola (Aldrich, 1996, 85). 3. Ethanol: Ethanol has emerged as a successful alternative to fossil fuels in Brazil where more than 4 million vehicles on ethanol based fuel and it is finding increasing application in the world as well 4. Hydrogen: : There are great interests in using hydrogen as fuel in transport industry due to the great flexibility of options and performance it offers. Hydrogen can either be used as fuel in place of gasoline in internal combustion engine or it can be used as energy carrier in fuel cells, the latter being the major research area in automobile sector (Aldrich, 1996, 87). Solar energy: : Solar power has turned as a dependable source of energy in areas other than transport. All the initial costs are high in maintaining a solar energy power plant, its been shown that with increasingly sophisticated technology and wider application the cost of installation as well as generation of electricity can get comparable to normal power plants. Mass Transport System Apart from introducing alternative fuel and technologies to replace and minimize fossil fuel consumption, another area where fuel consumption can be easily reduced is creating a more robust and functional public transport and mass transit system. It is cost effective and time consuming to redesign the existing public transport system, especially in major cities, to cut down fuel consumption by reducing number of vehicles on the road. Socio-cultural impact When fossil fuels were discovered around 150 years back, the existing technologies of steam engines were unable to utilize them. However, soon completely new technologies were developed in the face of these new energy sources and they were used to capitalize on the energy content and efficiency of fossil fuels. Soon petroleum fuels revolutionized the way the world moved and worked. The past 100 years of consumption has comprehensively depleted non-renewable petroleum deposits and estimates give another 50 more years before the remaining available sources would get almost exhausted. This fact is indeed a cause of concern, but only if viewed from existing technological frame. Declining petroleum resources offer the signal that its time to make transition towards different energy sources. Countries that would fail to read this signal or close their eyes to it are certainly heading for a major crisis. But fortunately the world has the capacity to read these signals and develop reliable intermediate technologies and systems such as hybrid electric vehicle, ethanol and public transit systems that would considerably reduce fossil fuel consumption without adding to infrastructure cost thereby extending the life period of petroleum reservoirs. Meanwhile research can take place on new age technologies such as fuel cell and solar photovoltaic cells to complete replace fossil fuels as a source of energy. It is possible that if government and industry institute providential policy measures, there would be a host of alternative technologies in transportation sector by the time petroleum oil would get exhausted. _ Reference Bob Aldrich..

Since its discovery 150 years ago, petroleum oil has become lifeline of the world. The entire structure of the modern mechanized world, consisting from transportation system, automobiles, airplanes, railways, ships to space rockets today operates primarily on the energy derived from the fossil fuels/petroleum oils. Apart from being mainstay of the transportation sector, petroleum products have also found wide application in a large range of core infrastructure industries that are essential for survival of industrial processes and basis of existence of modern world. We will write a custom essay sample on Alternative fuel technologies or any similar topic only for you Order Now This dependence on exclusive use of petroleum resources of world has become cause of serious concern among policy planners. Petroleum resources are very limited and they have cannot be continuously exploited to meet human demand. According to varoius studies and estimates, the total oil stock of world t is expected to last for another 50-75 years if world continues to consume them at present rate. After that the cost of extraction of remaining petroleum products would rise greatly. It would become so costly that benefits obtained from oil would be lower than expenditure incurred on them. Thus world may need another resources of energy to exist. These fears and concerns have already generated intense research in alternative technologies to meet the future energy needs in the face of an overhanging petroleum crisis. The large part of the oil consumption takes place in the transportation sector, which accounts for the 69 percent of the total oil consumption in the US alone (Basic Petroleum Statistics, 2007). Overall there are five major sectors accounting for petroleum oil consumption. These sectors, along with their consumption share in year 2005 are (Petroleum-EIA, 2006) 1. Domestic/Household: Consumption in 2005 was 869 thousand barrels of petroleum per day 2. Commercial: 386 thousand barrels of petroleum per day 3. Industrial: 5061 thousand barrels of petroleum per day 4. Electric Power production: 545 thousand barrels of petroleum per day 5. Transportation: 13, 825 thousand barrels of petroleum per day. The consumption pattern in the transportation sector shows that consumption is highest for motor gasoline. Average daily consumption of motor gasoline in U. S, according to Petroleum data (EIA, 2005) is 8933 thousand barrels per day. Distillate fuel oil is the second most consumed petroleum product with daily consumption at 2817 thousand barrels. These figures show that U. S would be dependent on oil imports for present and future if it carries on the present rate of consumption. U. S has a fleet of 210 millions vehicle that depend entirely upon motor gasoline for their functioning that makes it very difficult to reduce oil consumption. (Hirsch R. L, Bezdek R, Wending R, February 2005, 4). As on 1st January 2006, the total proven oil reserves with U. S was just 21. 6 billion barrels, which means that in future U. S would be forced to rely almost completely on oil imports for its entire transportation requirements. As the closer sources shall run dry, U. S’ would be dependent on distant sources from where oil must be transported. The supply lines may become vulnerable to leakage and terrorist attacks and it would lead to rise in global oil price. The greater risk is certainly compromising with U. S national interests. The oil supply lines would always be at risk against subversive elements requiring another set of huge investment in ensuring safe transportation of oil to U. S onshore facilities. It will also place U. S interests in the hands of oil cartels such as OPEC that may freely manipulate oil supplies according to their own interests. The shortage of oil would increase greatly in coming times as oil demands are growing worldwide. Meanwhile China and India are also expanding their economy, transportation system and hence they would need more oil in future. Even at present rate there are serious doubts on the secure prospects of future supplies within next 50 years time frame, and the rising consumption rates threatens to bring the approaching crisis nearer. United States has thus a great responsibility to secure its future interests without sacrificing its present requirements and needs. This issue forms the topic of the next section. Alternative fuel technologies The forthcoming oil crisis has finally moved policy makers in US. A number of approaches are suggested that include a. imposing taxes on oil consumption b. using tradable gasoline permits and c. exploration of new sources of oil ( Deutch J, Schlesinger J. R, Victor D. G. 2006 ). However, the urgent need of situation demands methods that would sustain the present structure while safeguarding the future against depleting sources and rising petroleum prices. As the world’s oil reserves are limited, even measures such stagnating oil consumption and using oil more efficiently are just helpful in delaying the inevitable without offering any permanent solution to the issue. Oil reserves are going down steadily and within a couple of decades prices will soar up inexorably disrupting the economy, industry and society in turn. The only practical solution to this problem is technological innovations in energy field that can reduce dependence on petroleum oil by providing alternative and sustainable sources of energy. It shall serve two immensely useful purposes that are a. minimizing U. S dependence on foreign oil and b. preventing the environment from damages associated with use of petroleum oils and products. The certainty of oil exhaustion has inspired efforts from both government and corporate sector to research and develop the new fuel technologies as a providential measure for survival, growth and progress in forthcoming days of oil crisis. Past decade has seen great move on technological researches in alternative fuels. Various new techniques and models have already been introduced in the market to test their viability and capacity to successfully replace petroleum as chief source of energy. Most of these innovations are specifically aimed at transportation sector because it is the chief consumer of petroleum oil and as principle cause of increasing oil imports. Due to distinct requirements of different sectors in transportation, there are various technologies. You read "Alternative fuel technologies" in category "Papers" Passenger vehicles, public transport vehicles and freight transportation carry specific needs that are difficult to be met by a single alternative fuel technology. Some of the major and most popular of these technologies, where majority of research and development has taken place, are (Aldrich, 1996) 1. Hybrid Vehicle 2. Bio-diesels 3. Ethanol 4. Hydrogen and 6. Solar energy Following section discusses the technology used in each of these new vehicle-systems and their benefits over conventional gasoline based internal combustion engine. Hybrid Vehicles: As the name suggests, hybrid vehicles combine dual technologies for their operation. Technically they are hybrid electric vehicle with an electric motor that drives the vehicle (Hoogma, Kemp, Schot and Truffer, 2002, 41 ). In the case of a typical electric vehicle, hydrogen fuel cell or chemical batteries such as advanced sealed lead battery, nickel cadmium and lithium ion are used for auxiliary power (Aldrich, 1996). However in the hybrid electric vehicles, the electric drive technology is combined with a gasoline-based power generator for running the electric motor and charging the batteries. Hybrid vehicles are either full hybrid or mid hybrid. A full hybrid vehicle can move forward from standstill purely on electric power while a mid hybrid requires gasoline power for initial movement, although both technologies concentrate on maximum utilization of electric motor power while reducing the use of gasoline as far as possible (Hybrid Terms, 2007). The electric motor and internal combustion engine (ICE) are connected either in parallel or in series in a hybrid vehicle. In parallel hybrid cars, power to engine is supplied by both the electric motor and internal combustion engine while in the series hybrid car the gasoline engine powers the electric motor and batteries to generate electricity, without directly providing power for the vehicle (Hybrid Electric Vehicles, 2007). There is another category of hybrid vehicles, called as ‘plug-in hybrid’ that can operate as a full electric vehicle. They require some additional batteries and use electricity net to charge the batteries thereby minimizing gasoline use to its lowest possible levels (Hybrid Terms, 2007). All hybrid electric vehicle use computer that constantly monitors speed, power required and charge conditions of batteries (Hybrid Electric Vehicles, 2007). Hybrid vehicles offer numerous benefits over the conventional gasoline based ICE, some of which are (Hybrid Electric Vehicles, 2007; Sanna, 2007, 12; Aldrich, 1996, 88 ) 1. Hybrid vehicles are extremely fuel efficient, with most of the driving thrust coming from electric power. 2. Unlike electric cars, they offer unlimited range of traveling and transportation 3. Hybrid technology is combination of the proven technology of ICE with electric motors, thus giving it reliability in the market. 4. Hybrid technology can be used in various sectors of transportation, from personal vehicles to heavy duty vehicles. In fact, both the major US car manufacturers, GM and Ford have come out with a range of hybrid vehicles, that are successful in market. 5. Plug in -Hybrid technology is even more fuel conserving and environmentally benign, cutting down CO2 emission by more than 30 % while using minimum possible use of gasoline. Hybrid vehicles offer the most reliable alternate technology which US can capitalize upon without risking any major upheaval in its current fuel-technology structure. These vehicles promise to drastically reduce fuel oil consumption, reducing the needs of oil imports, meanwhile purchasing time for completely oil free technology. Bio-diesel: Bio-diesel, as the term suggests, is a type of renewable fuel obtained by agricultural products and used as fuel in heavy-duty vehicles. The major sources currently under research for bio-diesel are soybean, rapeseed, corn, cottonseed, peanut, sunflower, and canola (Aldrich, 1996, 85). The process of making bio-diesel involves use of an alcohol such as methanol which is treated with oil of selected agricultural produce to form glycerin followed by separation of fatty esters, recycling of excess alcohol and purification of esters to produce a fuel that bears remarkable closeness to diesel, however with higher octane number (Aldrich, 1996, 85). Currently bio-diesel is used when blended with petroleum diesel, especially in European markets, with commendable results. Bio-diesel offers a host of benefits over conventional petroleum diesel, some of which are (Faupel and Kurki, 2002, 1). 1. Reduction in vehicle emission leading to environment safe emission standards 2. As bio-diesel is an excellent lubricant it helps to prolong engine life 3. As the fuel is non-toxic and easily biodegradable it presents high safety standards in storage and transportation. 4. It will give boost to agricultural productions 5. It poses significantly lower health risks than petroleum diesel, successfully meeting health requirement standards established by Clean Air Act Amendment of 1990. 6. The technology of bio-diesel doesn’t require any major altercation in present engine technology and infrastructure models, making it a popular choice in alternative fuel category. 7. The fact that bio-diesel can be completely synthesized domestically gives US a great opportunity to curtail its dependence on fossil fuel, curb imports, optimize its economy and make a transition towards a secure and sustainable future. Bio-diesel has gained wide acceptance as a viable alternative for fossil-diesel and it is increasingly used in mass transit system, freight transportation and heavy duty vehicles Ethanol: Ethanol as a very long history as an alternative fuel, and it was tried in even 1880 as a fuel option for Ford cars (Aldrich, 1996, 51). Ethanol is derived from agricultural produces by process of fermentation and distillation to form a high-octane liquid fuel. Normally ethanol is not used alone as a fuel, instead it is blended with gasoline in ratio of 85 percent ethanol and 15 percent gasoline to form a fuel E-85, which is approved as an alternative fuel in US (Ethanol, 2007). The vehicles run on this fuel are called as flexi fuel vehicles. Ethanol has emerged as a successful alternative to fossil fuels in Brazil where more than 4 million vehicles on ethanol based fuel and it is finding increasing application in US as well. The benefits of using ethanol are multifold and they include (Ethanol, 2007) 1. Ease in use: Although E85 engine is somewhat different than ICE, it is possible to alter the existing ICE to accommodate E85 as the fuel 2. Reduced petroleum consumption: Increased use of E85 promises considerable reduction in use of fossil oil. 3. Renewable and sustainable fuel: E-85 is organically synthesized. It is renewable as ethanol can be made from waste bio products, optimizing the energy sector. 4. Environment compatibility: Vehicles using E-85 produce around 50 percent less smog in emission 5. Flexible fuel options: Vehicles using E-85 as fuel can also operate on gasoline, which is useful in case of non availability of E-85 Hydrogen: There are great interests in using hydrogen as fuel in transport industry due to the great flexibility of options and performance it offers. Hydrogen can either be used as fuel in place of gasoline in internal combustion engine or it can be used as energy carrier in fuel cells, the latter being the major research area in automobile sector (Aldrich, 1996, 87). Generally, hydrogen is obtained by decomposing hydrocarbon fuels, electrolysis of water and photolysis. It is stored directly in form of gas, liquid or as chemically with metal hydrides (Hydrogen Economy, 2002, 2). Due to its low energy volume, direct use of hydrogen as a fuel would require considerably large volumes to fuel the vehicle. On the other hand, hydrogen is extremely efficient in fuel cells. In a fuel cell, hydrogen combines with oxygen to produce electricity, Use of hydrogen offers following advantages (Hydrogen Economy, 2002; Aldrich, 1996,87) 1. It is the most abundant element in universe and hence practically inexhaustible as a source of energy. 2. When burned it produces water vapour as only by product. 3. Hydrogen can be used a fuel directly in ICE, requiring no modification in engine design. 4. Hydrogen fuel cells involve no pollution, and provide higher efficiency of the order of 45 percent in combustion. 5. In case of any accidents, hydrogen powered vehicle are likely to cause less damage due to light chemical nature of hydrogen. Solar Power: Use of solar power as energy in transportation sector has been subject of intense technological research. While the solar energy has found wide application as domestic energy supply, there are difficulties in their application in transport sector. Photovoltaic cells, that absorb sunrays to provide electricity, are inefficient under the current technology strains and unable to generate even a fraction of required power to drive a normal passenger vehicle. However, solar power has turned as a dependable source of energy in areas other than transport. All the initial costs are high in maintaining a solar energy power plant, its been shown that with increasingly sophisticated technology and wider application the cost of installation as well as generation of electricity can get comparable to normal power plants (Borowitz, 1999,112). Conclusion When fossil fuels were discovered around 150 years back, the existing technologies of steam engines were unable to utilize them. However, soon completely new technologies were developed as new energy sources were discovered. They started to use the energy content and efficiency of fossil fuels. Soon petroleum fuels revolutionized the way the world moved and worked. The past 100 years of consumption has comprehensively depleted non-renewable petroleum deposits and estimates give another 50 more years before the remaining available sources would get almost exhausted. US has the capacity to read these signals and develop reliable intermediate technologies and systems such as hybrid electric vehicle, ethanol and public transit systems that would considerably reduce fossil fuel consumption without adding to infrastructure cost thereby extending the life period of petroleum reservoirs. Meanwhile research is continuing on new age technologies such as fuel cell and solar photovoltaic cells to complete replace fossil fuels as a source of energy. It is possible that if government and industry institute providential policy measures, there would be a host of alternative technologies in transportation sector by the time petroleum oil would get exhausted. Economic advantage of using alternative fuels Alternative fuel technologies carry great economic benefit for US. Presently USA is heavily dependent on imported petroleum fuel that accounts for massive expenditure in the federal budget. Increased use of alternative fuel technology would reduce this dependency, saving billions of dollars annually. Further, the domestic production, processing and maintenance of alternative fuel resources and vehicles would create more number of jobs, thus strengthening the economic conditions. Alternative vehicles would also create far less air pollution, which would help the quality of life with reduced lungs diseases, cancers, asthma and various other problems. It would also bring down the need as well as the cost of environmental cleanup, adding to economic benefits further (AFV-2000) Reference Alternative Fuel Vehicles, 2000, Climate Change Technologies, 21st Feb, 2007, http://yosemite. epa. gov/oar/globalwarming. nsf/UniqueKeyLookup/SHSU5BMSCX/$File/alternativefueledvehicles. pdf Basic Petroleum Statistics.

The mechanism driving the entire transportation system from automobiles, airplanes, railways, ships to space rockets is based on utilization of energy of petroleum oil. We will write a custom essay sample on Alternative fuel technologies or any similar topic only for you Order Now Petroleum products are also extensively used in a number of infrastructure industries that form the core of industrial processes and basis of existence of modern world. However, the petroleum resources of world are very limited and they cannot endlessly meet human demands. Various estimates have put the total extractable oil stock to exist for another 50-75 years if world continues to consume them at present rate. After that the cost of extraction of remaining petroleum products would become much more than the benefits obtained them and world would require new resources of energy to exist. These concerns have already spawned intense research in alternative technologies to meet the future energy needs in the face of an impending petroleum crisis. United States of America is world’s leading consumer of petroleum products accounting for approximately 25 % of total consumption of petroleum oil world over. In 2003, world’s consumption of petroleum oil stood at around 80 million barrels per day, out of which US’s share was close to 20 million barrel (Hirsch, Bezdek, Wending, 2005). To meet these huge petroleum demands US depends crucially on oil imports that is well above 50 % today and continuing to rise upward. This overwhelming dependence on imported oil poses various strategic and security challenges for US interests in the long run. The sharp oil price increases of 1973 and 1979-81 serve as testimony to the dangers of import dependence. Further as the oil sources would continue to deplete, the prices of oil would steadily and inexorably rise until the level when world is faced with an acute fuel crisis. Based on these observations it’s vital that U. S explores alternative technologies and fuels to sustain its development and growth structure. Need of alternative fuels The continuous rise in U. S oil consumption has forced it to rely increasingly on imported oil to meet its expanding requirements. As of today with its 20 million barrel per day consumption U. S is the largest consumer and importer of oil, surpassing the combined consumption of Japan, Germany, China, Russia and South Korea (Reardon, 2004).. The share of oil in total energy produced in USA is just 17. 2 percent while in consumption it rises to 40 percent that explains the need for huge oil import. Imports constitute 11 million barrels per day that is more than the aggregate oil import of Japan, Germany, and South Korea (Reardon, 2004). The bulk of the oil consumption takes place in the transportation sector, which accounts for the 69 percent of the total oil consumption in US (Basic Petroleum Statistics, 2007). Consumption stands highest for motor gasoline. Average daily consumption of motor gasoline in U. S, according to Petroleum data (EIA, 2005) is 8933 thousand barrels per day. Distillate fuel oil is the second most consumed petroleum product with daily consumption at 2817 thousand barrels. These figures give a realistic view of inevitable oil import dependency U. S for present and future if it carries on the present rate of consumption. Indeed the chances to curb the massive oil imports are slim considering the fleet of 210 millions vehicle that depend solely upon motor gasoline for their functioning (Hirsch R. L, Bezdek R, Wending R, February 2005, 4). As on 1st January 2006, the total proven oil reserves with U. S was just 21. 6 billion barrels, which implies that in future U. S would be forced to rely almost completely on oil imports for its entire transportation requirements. As the closer sources shall run dry, U. S’ dependency would shift to further sources from where oil must be transported over vulnerable supply lines, leading to rise in global oil price. The greater risk is certainly compromising with U. S national interests. The oil supply lines would always be at risk against subversive elements requiring another set of huge investment in ensuring safe transportation of oil to U. S onshore facilities. It will also place U. S interests in the hands of oil cartels such as OPEC that may freely manipulate oil supplies according to their own interests. Part II: Alternative fuel technologies The impending oil crisis has finally stirred policy makers in US. A number of approaches are suggested that include a. imposing taxes on oil consumption b. using tradable gasoline permits and c. exploration of new sources of oil ( Deutch J, Schlesinger J. R, Victor D. G. 2006 ). However, the pressing need of situation demands measures that would sustain the present structure while safeguarding the future against depleting sources and rising petroleum prices. As the world’s oil reserves are finite, even measures such stagnating oil consumption and using oil more efficiently are just helpful in delaying the inevitable without offering any permanent solution to the issue. Oil reserves are going down steadily and within a couple of decades prices will soar up inexorably disrupting the economy, industry and society in turn. The only practical solution to this problem is technological innovations in energy field that can reduce dependence on petroleum oil by providing alternative and sustainable sources of energy. It shall serve two immensely useful purposes that are a. minimizing U. S dependence on foreign oil and b. preventing the environment from damages associated with use of petroleum oils and products. The certainty of oil exhaustion has inspired efforts from both government and corporate sector to research and develop the new fuel technologies as a providential measure for survival, growth and progress in forthcoming days of oil crisis. Past decade has seen great thrust on technological researches in alternative fuels. Various new techniques and models have already been introduced in the market to test their viability and capacity to successfully replace petroleum as chief source of energy. Most of these innovations are specifically aimed at transportation sector owing to its liability as chief consumer of petroleum oil and as principle cause of soaring oil imports. Due to distinct requirements of different sectors in transportation, the technologies vary How to cite Alternative fuel technologies, Papers

Paternity Leave for Men free essay sample

In society today, gender equality is becoming a big deal. Maternity leave has never been a questionable topic for new mothers, however it becomes controversial when it comes to new fathers. It is of extreme importance not only to the mothers but to the fathers as well. It is a great deal for new dads to share with the early bonding experiences and care for both mother and child. The men should be able to get a decent amount of time off to be able to share in this very special time. If companies offered this option for men, it would be a huge ordeal. They would be able to attend the birth and any important appointments that need to be attended. With paternity leave the men are given the privilege of being able to share in on the first stages of the child’s life. They also get the opportunity of being there for the child so dad can get to know the child and learn the needs the child has. We will write a custom essay sample on Paternity Leave for Men or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page â€Å"The increase in the number of men taking leave may be attributed in part, says Doucet, to changes made to the Employment Insurance Act in 2000, which increased the total parental leave time from six months to one year, thus allowing more time for dads to bring up 2baby†(National Post 2007). A trusted pediatrician has to be found following the birth and fathers can assist the mothers with this process. Paternity leave also will allow both parents time to get daycare arrangements together if both parents have to return back to work. Having dad around would be beneficial to mom if she delivered baby by Cesarean. This procedure is very painful and forces mom to limit her mobility and lifting. After this surgery, it is very important that mom has someone around to help her throughout her healing process. Child birth is a lot of hard work. It can really take a lot of the new mother. A new mother is normally emotionally and physically drained after giving birth. That is why it is very crucial for companies to allow men paternity leave so that they can help with the rigorous routine that they now have to get used to. A lot of mothers just want to come home and sleep. This is where dad comes in and gives mom that break she needs. During that time of paternity leave, â€Å"only 13 percent of employers in this country offer men any paid time off for birth or adoption† (The Record 2006). All new mothers need assistance when it comes to a new baby. Babies require a lot of attention and sometimes mommy will not always have the energy to do a whole lot at first. Paternity leave for new fathers would be not only rewarding for the new dad when it comes to bonding, but also prove to be very beneficial to the new mother as well.

CET 2501-Cedar Branch library Essays - Construction,

CET 2501-Cedar Branch library Paul Stiles Greg Armour 4-27-17 Water consumption is one of the biggest issues with the world today. Cedar Rapids Public library has set a good example on what to do. The library has a very water efficient landscape they use no potable water to water plants. In order to gain the LEED platinum certification they have to implement reduction methods by any combination of these things: Plant species, density and microclimate factor.Irrigation efficiency.Use of captured rainwater.Use of recycled wastewater.Use of water treated and conveyed by a public agency specifically for nonpotable uses. The use of captured rainwater is a brilliant idea using the rain for a good thing instead of letting it just fall from the roof to the ground wasted. Using recycled wastewater is another idea with brilliant effects. If you want to have a fully operational system you need to be able to handle the water you can collect through efficient irrigation and using better water holding species. Another area to complete in order to gain LEED certification is in water reduction. For percentage of water reduction you get a certain amount of points for 30% you get two points for 35% you get three points 40% you get four points. Above are ways they can use fixtures to improve water saving methods. Another important aspect to gaining the LEED certification is energy saving or optimization of energy. To achieve increasing levels of energy performance beyond the prerequisite standard to reduce environmental and economic impacts associated with excessive energy use. Option one "Whole building energy simulation." "In order to get this done they have to Demonstrate a percentage improvement in the proposed building performance rating compared with the baseline building performance rating. Calculate the baseline building performance according to Appendix G of ANSI/ASHRAE/IESNA Standard 90.1-2007 (with errata but without addenda) using a computer simulation model for the whole building project. Projects outside the U.S. may use a USGBC approved equivalent standard" The purpose of this analysis was to: process energy is included in the office and general miscellaneous equipment, computers, elevators and escalators, kitchen ,cooking and refrigeration, laundry washing and drying, lighting exempt from this is the lighting power allowance. On site renewable energy is a very important thing to have. Making your own power is a very helpful thing when it comes to saving money. Oddly enough this building doesn't have any points for this. What it lacks in renewable energy it makes up for with green energy. The intent of this is to encourage the development and use of grid-source, renewable energy technologies on a net zero pollution basis. This is measured off of energy consumed This is building is definitely an innovation, but what about it's design? The design innovation category was very helpful in what to find to make it such an innovation.The intent of this is to provide design teams and projects the opportunity to achieve exceptional performance above the requirements set by the LEED Green Building Rating System and/or innovative performance in green building categories not specifically addressed by the LEED Green Building Rating System.There are three paths you can take to acquire this: Path one innovation in design, path two exemplary performance, and path three pilot credit. In path one there are four things to do to get it: The intent of the proposed innovation credit.The proposed requirement for compliance.The proposed submittals to demonstrate compliance.The design approach (strategies) used to meet the requirements. In path two you need to achieve exemplary performance in an existing LEED 2009 for New Construction, Schools and Core Shell pre requisite or credit that allows exemplary performance as specified in the LEED Reference Guide for Green Building Design Construction, 2009 Edition. An exemplary performance point may be earned for achieving double the credit requirements and/or achieving the next incremental percentage threshold of an existing credit in LEED. In path three you have to attempt a pilot credit available in the Pilot Credit Library. Register as a pilot credit participant and complete the required documentation. Projects may pursue up to 4 Pilot Credits total. In regional priority credits this building once again shows how good it actually is. In development density and community connectivity there are

The Use and Abuse of Antibiotics

The Use and Abuse of Antibiotics What is an antibiotic? What is this 'miracle drug' that everyone talks about? There is a lot about antibiotics that we should all be more aware of.The word 'antibiotic' actually means 'anti-life'. The most common definition that we use for an antibiotic is: any substance produced by a microorganism that harms or kills another microorganism.There are many different kinds of antibiotic substances, most of them are natural products that certain bacteria and fungi (molds) produce and send outside of their cells. About 90% of the antibiotics we use today, are originated from bacteria. However there are a couple of antibiotics that were created from scratch in laboratory. These totally synthetic antibiotics are designed to inhibit some process previously identified to be completely unique to bacteria, and necessary for the bacterium to remain alive.Bacterium in the wild suffers a constant competition for available nutrients. Therefore if they can develop a substance that can cripple or ann ihilate their competitors then they have an advantage.Pseudomonas aeruginosa IMP-1- Metallo-betalactamas...So, even though these microorganisms do not have the ability to decide what substance to produce, through several mutations and additional events, they are capacitated to compete and consequently to survive more readily within their environment.We use antibiotics for a different purpose, of course, to help us kill harmful bacteria that cause us infection and disease.Scottish physician Alexander Fleming rediscovered in 1928 what Ernest Duchesne, a French Student, had initially discovered in 1896; the first and most famous fungus, Penicillium, which conceived the first identified microbial antibiotic, penicillin.Commercial methods for penicillin for human use were only developed in 1941 at the time of World War II. Howard Floerey and Ernst Chain made a major effort to try to make penicillin available to all of the British, U.S., and other allies...

Critically discuss the specific protections afforded to medical Essay

Critically discuss the specific protections afforded to medical personnel, clergymen and journalists under international humanitarian law - Essay Example Giving special protection to specifically listed persons can be traced from the earlier versions of humanitarian laws. There has been extensive as well as futuristic development of treaty rules pertaining to this area of special protection till now. To this effect the Geneva conventions along with the Hague regulations have a status which is purely customary. The various laws framed for the protection of specific persons are the Lieber code of 1863 which included rule for protection of hospitals as well as cultural property. The Geneva Convention of 1864, had rules for the safety of medical personnel, transport and equipment. The 1899 and 1907 Hague regulations containing rules to exclude edifices related to religion, art, science, charity, and hospitals etc. The 1907 Hague convention also contained rules to spare historic monuments form bombardment. Moreover the two Hague conventions also contained directions not to target journalists at the time of war. The 1949 Geneva Convention had many provisions that exclude targeting of specifically listed persons as well as objects. The Geneva Convention I also contained specific provisions to protect hospitals, ships used as hospitals and medical people and equipments. The Geneva Convention IV includes detailed regulations concerning hospital zones, safety zones and civilians who are not yet occupied from the effects of the war. The Geneva convention I also includes regulations for the protection of national Red Cross societies and other voluntary aid organizations. However the four Geneva conventions do not include any special provisions regarding journalists. The third convention contains a statement that the war correspondent if captured should enjoy the status of a POW. No provisions are there which avoids a journalist from targeting. The Geneva Convention has included provisions regarding protection of women and her honour particularly from atrocities like rape

Semiconductor devices and circuits Coursework Example | Topics and Well Written Essays - 1500 words

Semiconductor devices and circuits - Coursework Example Each atom after sharing electrons will attain a full outer shell. Conductors: Conductor materials have large number of free electrons and thus conduct easily. Examples of a good conductor are copper and aluminum and they have, at room temperature, many electrons for conduction. Insulators These are materials which do not conduct. For insulators, there is a very large gap between the two bands i.e. conduction and valence bands. Insulators can only conduct at extremely high temperatures or when they are subjected to very high voltage. Examples of insulators are, wood, glass, paper and mica. Semiconductors: These materials are between conductors and insulators. They are neither conductors nor insulators. They can easily conduct at room temperatures. Examples of these materials are silicon and germanium. Intrinsic semiconductors: These are pure semiconductors since the content of impurity is minimal. These materials are cautiously refined to achieve this form of purity. When intrinsic se miconductors are subjected to room temperature, valence electrons absorb heat energy breaking the covalent bond and move to conduction band. Electrons and holes conduction In intrinsic semiconductors, holes and free electrons are the major charge carriers. Holes and electrons which are generated at room temperatures move in a random motion and can’t conduct any current. ... This allows electric current to flow as a result of electrons movement in the conduction band. The motion of holes in semiconductors is opposite to that of electron. As a result of electrons escape from valence band to conduction band, holes are created in the valence band. When current is applied the electron break and moves to feel the holes present, at the same time this electron leaves another hole and this process continues. The movement of these holes in the valence band leads to current flow referred to as whole current. Extrinsic Semiconductors Small amounts of other materials are added to intrinsic semiconductor to alter the properties and this result to extrinsic semiconductor. This is process of adding an impurity to improve the conductivity of the semiconductor is referred to as doping. The materials used as impurities are called dopant. These semiconductors are the most widely used in practice since they have better conductivity compared to intrinsic semiconductors and a re used in manufacture of electronics components such as transistors and diodes. There are two types of extrinsic semiconductors and each depending on the type of impurity used. They are n-type and p-type. N- Type Atoms with five electrons in their outer most shell are referred to as pentavalent atoms. When these pentavalent atoms are used to dope intrinsic semiconductors, they donate a free electron to the semiconductor and they are called donor dopers. Examples of donor materials are phosphorous, arsenic and bismuth. The resulting semiconductor has a large quantity of free electrons and is called n-type semiconductor. Example of n-type semiconductor formation is when arsenic atom with five electrons on the outermost shell combines with silicon with four

3 Dimensional Modelling in Architectural Design

3 Dimensional Modelling in Architectural Design Computer software technology is an important part of computer technology, because computer is made up of computer software, computer software technology is one of the most concerned area in the computer technology, human today manipulated by the fast development of computer technology. Todays software development tends to be more professional and directionality, as a student whom is studying design, we are often in pursuit of better results and had to use special design software to achieve our goals. As a design student we must be all familiar with computer 3 dimensional modeling software programs Today I’m going to discuss the most common known and most frequent used 3 dimensional modeling software program using by not only design student but also many professional architecture designers and jewelry designers, products designers, urban, interior, exterior designers! Introduction to 3 dimensional modeling: The so called 3 dimensional, according to the theory, is where the human describes any point in three-dimensional space by means of three coordinates, and we labeled each coordinates, the x coordinate, y coordinate and the z coordinate, where the x coordinate represent left and right of a space, y coordinate represent up and down of a space and z coordinate represent front and back of a space. Thus it concluded the formation of the human stereoscopic vision; the 3 dimensional models are made up of 3 dimensional computer software programs, this to achieve further development of computer technology in variety of industries. We live in a three-dimensional world; meanwhile, we also live in an informatization era and informatization era which is characterized by computers and digital. Computers are widely used in all industries. Today’s two-dimensional imaged computer would no longer be satisfied, we wanted the computer to be able to express a more reality form and the 3 dimensional modeling software programs can turn this into reality. The so-called three-dimensional modeling is to use 3 dimensional data to build up existing objects in reality or our imagined objects and reconstructed this objects in computer. It includes the basic information such as the 3D coordinates define the locations of object points, the color of the object surface, Transparency, and texture etc†¦3 dimensional modeling programs is widely used in various areas, and it provides an Intuition, so 3 dimensional images play an increasingly important role in various fields. There are many benefits and good reasons of why using 3 dimensional modeling software programs, Firstly, knowing how to use 3 dimensional computer software programs can develop our intelligence to enhance our imagination. During our study life time, Because of our learning system and the environment, we have become less able to produce unique imaginations and less able to elaborate on ideas. Mainly because of the stress we are dealing with each day, we have become uncreative; most of the time we thought copying would be a much simpler way to produce work. However knowing how to use a 3 dimensional modeling software program will fill this vacancy. Secondly, those who know how to use 3 dimensional modeling programs can make abstract graphic image become more intuitive and easy to understand. Introduction to Rhino 3 dimensional modeling techniques: Rhino is a powerful three-dimensional software program; it is the first powerful AGLib NURBS modeling technology complete the introduction of the Windows operating system software. Rhino is easy to use, highly flexible and highly accurate modeling tools. Rhino provides almost all tools to be used in the creation of three-dimensional models; it can create any imaginable shape, it can also create any project cannot be completed in reality therefore Rhino is a very powerful 3 dimensional modeling making software program 3 dimensional modeling making is the basic consensus in design making process, without model building, the design idea would be difficult to present. It plays an important part in the design process, because a realistic 3d model is able to reflect the turn quality and the material of the model, it truly made our design ideas becomes real. Rhino 3 dimensional Modeling discussion: Modeling making is the basic modeling technique; Todays 3D modeling software programs has its own unique modeling system, modeling method can have many different types, but the main 3 types are the NURBS modeling, Polygon modeling and Patch Modeling. The rhino software program provides NURBS modeling making, subdivision modeling, Carving Modeling and polygon modeling. Polygon modeling is the oldest method, and is also the most common method; polygon modeling is the splice of triangles and quadrilaterals, the 3 dimensional model we see on screen is connected by the â€Å"face† of polygons,and every â€Å"face† are different sizes and orientations, by arrenging these â€Å"faces† it complete a very complex 3 dimensional model. NURBS modeling, Is the most popular modeling method, it offers great flexibility and precision for handling model shapes, is a much more simply and efficient method, it seems everyone can create their 3 dimensional model using the NURBS technology. Subdivision modeling is also sometimes called the sub modeling, is a way of as it named, it applies subdivision surfaces to create new geometry that has the result of smoothing out geometries, like cubes, pyramids, it produces smooth out render shapes. Usage of rhino 3D modeling in my project analysis: To be able to present my imagined design idea to my audience and translate my imagined design idea to reality, at this stage I began to use 3 dimensional software program rhino to build my imagined 3 dimensional model. To build up a 3 dimensional model using rhino, it sometimes take longer times, therefore it would be better for us to choose a final development model to build instead. This way we can concentrate on every details of the model. When using a 3 dimensional modeling program creating a model, we need to think carefully about its structure, we must have a full understanding of this model, if we are not certain about the model structure then the model that we are going to build would not have a realistic appearance, the details would be missing. Therefore I prefer the quality, not the quantity. The usage of this 3 dimensional software program rhino has clearly improved the quality of my design, rhino provides models with texture, the textures of the model is actually just an image we see on screen, but after rendering, it can make the model appeared more detailed and more realistic. Compared with wireframe models, it is a higher level technology. Design process: Collect relevant information, research relevant artworks Design concept: sketch out all usable and suitable ideas Deleting unusable and unsuitable ideas Set up a final development model 3 dimensional modeling making using 3 dimensional software program rhino Knowing how to use this 3 dimensional programs rhino, I have learned many valuable know ledges, firstly, to have a well presented three-dimensional model is a very important process when creating a design work, without a good 3 dimensional model, it is impossible to complete a good design work. And with the help of this 3 dimensional program rhino, it made design work become smooth, easy and efficient. Design concept: My design is called the rain angle, the rain angle was inspired by the weather of Auckland, where the i did a record of the weather of Auckland, i noticed the weather of Auckland was interesting due to the quickly speed change of temperature. The temperature is colder in the morning, the temperature is hotter during lunch time, the temperature rises at lunch time and temperature drop in the late afternoon. i also noticed Auckland is always high in level of humidity, before it rains, humidity usually increases, When it is raining, relative humidity draws near 85%-100%,Auckland average humidity is between 75%-98%, therefore it sums up a conclusion that Auckland rains very frequently, i did a record of Auckland weather by collecting data on the website â€Å"the accuweather.com† the red dot represents a day it rained, and base on these red dots, I did a graph that shows the rain data of Auckland! Yet Auckland has unstable temperature, and rains frequently, but it does not effect on wild life’s living, people always say New Zealand is the last paradise for the birds, as New Zealand has more species of flightless birds – both living and extinct – than any other country. i recorded a weather data graph and translated the weather data graph of Auckland into a 3 dimensional model (the rain angle) the flow and the geometry allows the model to collect rain water, rain water will be reused by birds, birds’ uses as a water tank and a bird’s bath! This model is specially designed for birds.

Leukemia and Its Treatment Essay -- Cancel Health Medical

Leukemia is something that we hear about a lot. I believe that people do not understand exactly what leukemia is and how dangerous it can be, I chose this topic to try to help them understand. In this paper I will explain what leukemia is and what treatments you can choose from to treat the cancer. Leukemia is a type of cancer. Cancer is a group of more than 100 diseases that have two or more important things in common. One is that certain cells in the body become abnormal. Another is that the body keeps producing large numbers of these abnormal cells. Leukemia is cancer of the blood ce3lls. When leukemia develops the body produces large numbers of abnormal blood cells. In most types of leukemia, the abnormal blood cells and they do not function properly.(Cancer compass 10)   Ã‚  Ã‚  Ã‚  Ã‚  There are two major groups of leukemia they are grouped based on how fast they spread. Acute leukemia is a cancer that starts in the organs that makes blood, namely the bone marrow and the lymph system. Acute leukemia spreads very quickly. Chronic leukemia is when many white blood cells are made in the bone marrow. Depending on the type of white blood cell that is involved chronic leukemia can be classified as chronic lymphocytic leukemia or chronic myeloid leukemia. Chronic leukemia spreads slowly.( Longe,186)   Ã‚  Ã‚  Ã‚  Ã‚  There are many different types of treatment for leukemia the one that you receive depends on what stage the cancer is in and what kind of leukemia you have. Chemotherapy is one form of...
