Not all hybrids have electric motors and batteries

Not all hybrids have electric motors and batteries When it comes to transportation, hybridization is not new. Hybrid cars and trucks that combine an electric motor with a gasoline engine date back to the turn of the 20th century. Hybrid diesel-electric locomotives have been in operation for years, and in the 1970s, small numbers of diesel-electric buses began to appear. On a smaller scale, a moped is a hybrid - it combines the power of a gasoline engine with the pedal power of the rider. So, any vehicle that combines two or more sources of power is considered a hybrid vehicle (HV). Today, when hybrid and vehicle are used together - think Toyota Prius, Ford Fusion Hybrid or Honda Civic Hybrid - that vehicle, according to the U.S. Department of Energy, is a hybrid electric vehicle (HEV). Each of these vehicles combine an internal combustion engine (ICE) and an electric motor that receives electricity from a battery pack. Today’s gasoline- and diesel electric hybrid systems are very complex, high-tech wonders in design and operation. Components include controllers, generators, converters, inverters, regenerative braking and, of course, a battery pack - either nickel-metal hydride or lithium ion. HEVs offer benefits that their conventional gasoline or diesel counterparts do not have - increased fuel economy and fewer harmful emissions coming out the tailpipe. But to achieve the same results not all hybrid vehicles require electric motors and batteries. Here’s a look at three alternative hybrid systems. One is now employed in big trucks and could find its way into cars, one is likely to appear in a 2016 BMW and the third could be on the road in three years. Hydraulic - Not Just For The Big Dogs Last August I featured an article about a hydraulic hybrid system that has made its way into big diesel refuse trucks, the ones that come around once a week and pick up our trash. On a good day, a garbage hauler will eke out 4 to 5 mpg. Then there are all those icky, nasty pollutants pouring out of the exhaust stacks. But thanks to the United States Environmental Protection Agency (EPA), yes, those same government folks who monitor environmental laws and fuel mileage testing, a hydraulic hybrid system they pioneered increases fuel economy in the big rigs by as much as 33 percent and reduces carbon dioxide (CO2) by 40 percent. The principal of the hydraulic system is similar to a HEV. It recovers a portion of the energy normally lost as heat by the vehicle’s brakes. But instead of a battery pack, a hydraulic system uses pistons to capture the wasted energy by compressing nitrogen gas stored in a tank, called an accumulator. When the driver lets off the accelerator pedal, the wheels drive a hydraulic pump that pumps hydraulic fluid to compress the nitrogen gas and slows the truck down. When the driver accelerates, the nitrogen is allowed to expand and pushes a piston in a cylinder filled with hydraulic fluid. This action assists the diesel engine in turning the rear wheels. The hydraulic system performs remarkably well on the big dog trucks, but what about light duty trucks or passenger cars? The Center For Compact and Efficient Fluid Power (CCEFP), a National Science Foundation Engineering Research Center in Minneapolis, Minnesota is working on that. The center’s â€Å"Generation 2† vehicle - a Ford F-150 pickup - utilizes a custom-built continuously variable power split hydraulic transmission. It is complemented with hydraulic accumulators to enable hybrid operation. To be competitive, the system must demonstrate advantages over BEVs. Design specifications for the vehicle include: vibration and harshness comparable to a passenger vehicle; a 0 to 60 mph time of 8 seconds; climb a grade of 8 percent; emissions that meet California standards; and the big one, fuel economy of 70 mpg under the federal drive cycles. Steaming Along Twin brothers Francis and Freelan Stanley, inventors of the Stanley Steamer, would likely approve of BMW’s innovative use of the same principal that worked to power their steam engine cars more than 100 years ago to improve the efficiency in modern vehicles. Called Turbosteamer, this system uses wasted heat energy from an engine’s wasted exhaust gases to contribute power to the automobile. This steam assist system starts with a heat exchanger located between the engine and the catalyst that turns water into steam. The pressurized steam is then carried to what is essentially a small steam engine. A second, smaller steam engine produces a little more mechanical energy. I began following this technology in 2005 when BMW said the two steam engines combined generated 14 horsepower and 15 pounds-feet of torque on a 1.8-liter four-cylinder engine. Additionally, fuel economy improved by 15 percent in overall driving. The automaker also said it intended to make the Turbosteamer ready for volume production in a number of its vehicles within a decade. Well, it’s 10 years later, will it see production? Since then, researchers and engineers focused on reducing the size of the components and making the system simpler to improve dynamics. They came up with an innovative expansion turbine based on the principle of the impulse turbine. The system is now smaller, costs less and the developers say fuel consumption is reduced by up to 10 percent during highway driving. While the Turbosteamer can’t compare its greenness to the BMW i3 all-electric car, a 10 percent improvement in fuel economy for an â€Å"Ultimate Driving Machine† is nothing to sneeze at. It’s possible a Turbosteamer equipped BMW vehicle will be introduced next year. Not Just A Bunch Of Hot Air The idea that compressed air could power a viable zero emissions car has been pursued for years by many respected engineers. In 2000, there was much ado about a new compressed air, zero pollution vehicle from French inventor and Formula One engine builder, Guy Nà ¨gre. His company, Motor Development International (MDI), rolled out an urban-sized car, taxi, pickup and van that were powered by an air engine. Instead of those tiny, tiny explosions of gasoline and oxygen pushing the pistons up and down, like in a normal internal combustion engine, the all-aluminum four-cylinder air engine used compressed air for the job. A hybrid version, using a small gasoline engine to power an onboard compressor for a constant supply of compressed air, was claimed to be able to travel from Los Angeles to New York on just one tank of gas. In 2007 MDI signed an agreement with Tata Motors, India’s largest automobile manufacturer to produce air cars in 2008, followed by the hybrid version in 2009. No cars were produced. That’s perhaps one of the reasons compressed air-powered cars have been the butt of jokes among the green car community. Today, the number of jokes has diminished. That’s the result of Peugeot’s introduction of the 208 HYbrid Air 2L Prototype at the 2014 Paris Auto in October. (Full Review). It employs a compressed air tank that turns a hydraulic motor for additional power or zero emissions city driving rather than a battery for the same functions. Like a BEV, during normal driving the car is powered by the gasoline engine. Compressed air is called upon for additional power when passing or traversing a hill. In this situation, power from both the engine and hydraulic motor are directed to the front wheels via an epicyclic transmission, similar to the planetary gear set transmission used by the Toyota Prius. In city driving, where less power is needed and emissions-free driving is the priority, rather than power provided by a battery, the compressed air alone motivates the car. The compressed air tank is recharged when braking or by using part of the energy developed by the three-cylinder gasoline engine to compress the air. During the Pairs Show, Peugeot said if another large auto manufacturer would buy into the technology to enable production in enough numbers to assure manufacturing affordability, the HYbrid Air could be on the market in three or so years. Two reports from Europe are suggesting, without naming the car company, that Peugeot has found an interested partner. Last Word It’s not certain that any of these three alternative hybrid systems will be available in production vehicles, and if they are, what kind of an impact they will have in the marketplace. What is clear is, electricity in the drivetrain isn’t the only way to hybridize a vehicle.

Finance For International Business Essay Example | Topics and Well Written Essays - 2500 words

Finance For International Business - Essay Example The article presents the financing and the methods of capital budgeting. Capital budgeting is defined as the planning process which is applied by the managers of the company to decide whether the long-term investments are worth the supplying/funding of money through the capitalization structure of the company. Fenland Foods Plc should opt for debt financing method if it considers investing in the project in spite of the negative results of the Fresh Farm because it does not require sharing the company’s part with the investor. Financing through bank loan will be the better option because raising a loan through the bank will give the freedom to Fenland to run the Fresh Farm Foods Company without any intrusion from the lender. By opting for the bank loan, Fenland could also enjoy the tax benefits as the interest paid on loans are generally deducted from the income before computing the taxable income. The capital asset pricing model provides a practical risk measure that helps the investors to resolve what return they actually deserve for placing their money or capital at risk. It is recommended that Fenland Foods Plc should not undertake the project as the NPV of Fresh Farm Foods is negative and also the payback period is more than five years which signifies that Fenland will not be a ble to quickly pay the finances. It is also advised that if Fenland considers undertaking this project in spite of its negative result then they may invest  £400,000 which is less than the initial investment.

Clinical Audit Research Paper Example | Topics and Well Written Essays - 2500 words

Clinical Audit - Research Paper Example Between September 20th 2010 and September 22nd 2010, 21 surgical procedures were to be carried out on 21 patients. 11 elective patients were to receive Co-Amoxiclav. While some of them were to receive only Co-Amoxiclav others were to receive combinations that included Co-Amoxiclav. While 12 procedures out of 21 complied with guidelines the rest was of a diverse character such as non compliance, unavailability of guidelines and antibiotics being out of compliance guidelines. According to this analysis it is clear that antimicrobial prophylaxis was to be given to elective patients either a few hours before or during the procedure. Though the level of compliance was considerable there was no proper indication as to how much such compliance produced qualitative and quantitative positive results by way of increasing the degree of response by patients to antimicrobial prophylaxis. Between September 23rd 2010 and September 25th 2010, 14 surgical procedures were to be carried out on 14 patie nts. 7 elective patients were to be given Co-Amoxiclav. Only 4 patients out of 7 were given Co-Amoxiclav while others were given combinations that included Co-Amoxiclav. Only 9 procedures out of 14 complied with guidelines and the other procedures were of a different character. While some of them were to receive only Co-Amoxiclav others were to receive combinations that included Co-Amoxiclav. From September 29th 2010 to October 01st 2010, 25 surgical procedures were carried out on 25 patients....

Only 4 patients out of 7 were given Co-Amoxiclav while others were given combinations that included Co-Amoxiclav. Only 9 procedures out of 14 complied with guidelines and the other procedures were of a different character. For example there were cases of non compliance and therefore the efficacy of antimicrobial prophylaxis could not be determined. Between September 26th 2010 and September 28th 2010, 19 surgical procedures were to be carried out on 19 patients. 10 elective patients were to receive Co-Amoxiclav. While some of them were to receive only Co-Amoxiclav others were to receive combinations that included Co-Amoxiclav. For example Teicoplanin, Gentamicin, Metronidazol were other antibiotics received by the patients. 14 procedures were complied with the guideline out of 19 procedures while the other procedures did not comply with the guidelines due to various reasons such as missing guidelines, antibiotics being out of compliance guidelines and procedures being cancelled. From September 29th 2010 to October 01st 2010, 25 surgical procedures were carried out on 25 patients. 11 elective patients were given

The Change of Jem and Scout Essay Example for Free

The Change of Jem and Scout Essay She began to see how cruel the world could be to someone who is a little different or strange. She gained the knowledge of the pure hate that one man can show another. The kid’s relationship with Atticus starts out normal. Though, as the story progresses, they recognized he’s different then other men. This shows when Scout says â€Å"He did not do the things our schoolmates’ fathers did: he never went hunting, did not play poker or fish or drink or smoke. He sat in the livingroom and read† (pg 89). Atticus had the courage to take the case of a black man, Tom Robinson. It was obvious they didn’t stand a chance going against a white man in court but Atticus did it anyways. He did something that no other man would do, not for the glory, but because he can show a great example to his kids and it is the right thing to do. The kids learned not to be prejudice and not be ashamed if they have friends who are a different race then they are, for example Calpurnia. The way the children’s relationship changed about Boo is probably the most interesting part in the book. It went from an obsession to an unconditional love. First the children believed that anything that comes from the Radleys property is poison. Jem yells at Scout once saying about the Radley property: â€Å"Dont you know youre not supposed to even touch the trees over there? Youll get killed if you do! † (pg. 33). The kids didn’t know that Boo admired them, even though he barely knew them. After a while they noticed that Boo was giving them little hidden presents, and they realized that he is the one who folded and sewed together Jem’s pants. He showed an unconditional love that most people his age would not show. When Boo saved the children’s lives, he proved that he loved them. He was so kind that he risked his own life for the children, and that is why Scout grows to loved him, instead of being tremendously scared of him. Jem’s faith in truth and justice is very badly damaged. When the shameful courtroom proceedings are over he retreats into a troubled state of deep disillusionment. Prejudice and racism do not make any sense to Jem, because he never noticed it in his environment. He does not understand why all of this is happening. The kids matured a lot during the course of this book, especially Scout. She went from a six year old child with no knowledge of the real world to an about ten year old who had a lot of life’s most important lessons shown to her at a very young age. They had to learn, very quickly, that life would not always be easy, fun and fare. We cannot let children face the ugliness that they learned. It was too much, to fast, even for Scout who is so smart. We must show love to everyone so that children will show love back.

The conceptual idea of humanism has existed since before the years of Christ. Biblical records state that when man was created he was made in the image of God. This image has been passed down throughout the civilizations of Greece ,Egypt, and Roman times and it has been passed down to our civilization of today. The evidence of this is in the art of yesterday and the way we view art of today. The way we view art today is in such a way that we feel and conceptualize what we create. We create things in the image of how we view our life, our civilization, and our status in this civilization. In applying the things stated in the previous thought to the human life the result will be art . Culture is a distinct component of what society is. Culture is in all essence what culture does. The whole purpose of culture is to in a way define a specific race or creed. Culture is what makes us unique and very individual. An example of this is myself and my cousin named Brandon. We are both in the same family and we both have been raised with the same values but what makes us different is the culture we have adopted in our lives to help us define the way we feel about ourselves and the way we feel about society. I feel as if the afro-American race is moving in a progressive manner towards unity and he feels as if the Afro-American race as a whole is moving towards separation by the complexion of their skin. The culture that I have adopted has shaped my views and ideas and the culture he has adopted has shaped his thoughts and ideas. My ideas are not better than his nor are his better than mine ,just different. Civilization is defined as many things but you can only define what is civil for your own civilization. Many people have a definition of what a civilization is but when they make this definition it is by their own standards which is wrong. A civilization is a place or group of people who can defend themselves from enemies, get or create a quantity of food, establish a currency, and develop a trade with others. In America we view life as a sacred and very precious thing . In other countries death is viewed as the

Globalization, Culture and Indigenous Societies Essay

Globalization describe by Richard Wilk is the world wide impact of industrialization and its socioeconomic, political, and cultural consequences on the world, which include migration of labor, increaing spread of industrial technology. Technology is moving at a rapid pace, that when a indivdual purchases a computer of the shelf, the technology is already obsolete. With the advancement of technology, it is causing countries to become modernizied. Such as inda, which was at one point a third world, but is now becoming mecha, for new businesses. But with monderization, comes dependency, such as with the invetion of the car, we have become depenent on oil, such so that we no longer get the majority of our oil from america, but from other countries. Companys the exxion, pay a certain amount of money for this oil, and will sell it to the consumer for 3 or 5 times the amount they paid, knowing the that consumer will pay the price set by the company, thus exploiting the consumer. Companys our now exploiting other countries, like china, they will out source products to be built in china, and charge the chinese worker a wage of lets say 50 cents an hour, instead or the americans work $9. 25 an hour to make the same product. With the rapid expansion of globalization, has change a lot of countries, it has in some cases, destroyed cultures, mainly for the countires resources. With epansion can come cultural change, someimes it is forced, case in point the mbuti tribe. The Mbuti, had been in contact with ousiders for centuries, but chose to retain their tradional way of life. During the colonial peroid, government officials tried to resettle the mbuti. The resettling was a disaster. It isnt the first time a government has tried to move a society of peole, one such case is the native american of north america. The united states put the native amerians on reservation, one such tribe would be the navajo indians. Globalization has had negative impact on a lot of small societys. It has destroyed their culture, their land, the people themselves to some extent. But in bigger societys, it has caused a triving oasis. But the downfalls our dependency. If we were to gradually, incorpate globalization of what bigger societys, in to smaller societys it would allow the intergration of the old and new, to eventually over time, it would evolve into something new. Such inda, and its marriage practices, the man works the women takes care of the home, but there our some women who want to work and take care of the home. Chapter Globalization in latin america, africa and the caribbean Globlization had a major impact in latin amercia in the 1500s. During this time, a man named hernado, cortes a spanierd, help start a rebellion, in the aztec empire. He gave the aztects non native weapons such as guns, to rebel against their ruler, Montezuma. The aztec state quickly crumpled. But it didnt stop their, the spanish wanted more territory, with the help of their native americans, the went to conquer mesoamerica, including Mexico, Honduras, and guatemala as well as parts of norh amercia, such as california. They exploited the people and land, by developing mining, commercial agricuture, and live stock raising and trading. This drastically transformed the sociocultural systems of the the americas. In Africa, societies exploited the country but use of slavery. In Africa this system included slaves who were attached to the extended families and be came part of the domestic social unit and as such could marry, own property and were protected from mutilation and murder.. But in western countries thought of them as property and did not have personal rights, could never be incorporated into the owners domestic family or social system. In the Caribbean islands because they did not have a large agricutrual resource, the colonial powers intrduced commercialized agricutrual usually in the form of sugrar plantations. In some cases, globalization can back fire, is various parts of south america, revolts started happing, and with the migration of various, peoples, south america become intermingled. Religions evolved, as well as devolved. The globalization of africa and south america, drasically change its land scape and its people forever. Many people lost their homes as well as their heritage. The africans lost a country when they were brought to the americas to become slaves. They lost many freedoms.. Chapter 15 Globalization in the middle east and asia. Just as in latin america, africa and the Caribbean, globalization had a negative impact for coutries in the middle east and in asia. With colonization, can dieses, and death. At one point weastern societies, tried to change the religion of many countries in the middle east as well as in various countries in asia. For the most part they did not succeed. Just as in south america, when came to colonization in the middle east and in asia, there came revolution. But some were more peace then others such as mohandas gahdis protests for indias independence from the British. Unlike china’s protests which were more violent, which lead to china forming a communist movement. These revolts and protects, change many countries, thus forming newer countries in the process. When these countries changed, some became very wealth while others became poor, for example, some countries in the middle east, had oil, many others did not. In the middle east, the Islamic tradition and Arab culture influence the patterns of family life and gender. With the globalization of the middle east and asia, came change, but mostly the change was met with revolution and for the most part it was a very violet one. Some countries tried to isolate them selves such as china, from the rest of the outside world. When you have a society that is trying to drastically change another culture it is almost always going to be met with hostility. But what comes out of it, when the dust settles, it could be go or band. But usually the change eventually turns out to be good.

German Economy Essay

One of the major sectors of German economy is the exports of this country that has accounted for a great percentage of financial output. In this regard, more than twenty-five percent of the national German output has been due to the heavy exports that have increased significantly during the last decade. In the year 2004, GDP of Germany was contributed by forestry, mining, and agriculture sector at a very lesser extent, as compared to the other sectors in the country. Despite Germany is going through a high level of industrial revolution, forest has covered more than twenty-five percent of German’s territory. In the year 2003, more than seventy percent of Germany’s gross domestic product was accounted by services sector of the country. In this regard, more than seventy percent of the workforce was employed by this sector. On the other hand, metals, textiles, chemicals, vehicles, foodstuffs, and machinery are major imports of the country, which plays a vital and crucial role in the economy of Germany. In the year 2003, a positive of US$55 billion was the account balance of payments and currency of Germany. The paper will now discuss the abovementioned areas of German economy with detailed analysis, and hope will be beneficial for experts and economists in the better understanding of German Economy. In this competitive era, a number of economies are enjoying a vital position, and Germany is one of the countries that have been able to construct a very important place in terms of its economy. In terms of exchange rate of the United States, the German economy is considered the third largest out of the other major economies of the world. Moreover, the economy of Germany has a very strong power of purchasing, which has resulted in its place as the fifth largest around the globe. In the European continent, the economy of Germany is the largest of all the other economies, which has provided it with a number of opportunities and significance in this economic world. Geographically, Germany enjoys a central place in the continent, which is one of the other reasons behind the significance and exposure of opportunities to the German individuals and businesses. A number of difficulties and confrontations can be observed in the economic history of Germany, such as structural problems related to the East Germany, as well as, different structural problems that have continued since a last decade in the country. (Smyser, 1993) The German government has imposed and implemented a number of policies that have provided significant opportunities for its economy to strengthen in the world. In this regard, one of the major steps taken by the German government is the promotion of establishment of free enterprises, as well as, competition that has provided a competitive and friendly environment to the businesses and individuals in the country. However, various sectors are selected for the distribution of financial support by the state organizations. In the response of such steps taken by the government and related organizations, the economy of Germany has achieved a momentous space in the midst of other economic powers of the globe. In addition, different sectors have achieved strategic importance with the help of different policies by the German government. Thus, a number of factors and reasons are responsible and should be credited for the strengthening and powerful role that has been played by economy of the Germany. One of the major sectors of German economy is the exports of this country that has accounted for a great percentage of financial output. In this regard, more than twenty-five percent of the national German output has been due to the heavy exports that have increased significantly during the last decade. In the result, German economy has expanded traditionally in a macroeconomic manner with the support of heavy exports from different business sectors and industries of the country. Moreover, economic and political incorporation is another basic policy of the German economy, and such policy has been promoted on the continental level in the Europe. In the result, the European Union and its member countries have appreciated and encouraged the introduction and implementation of German economies policies at a higher extent. (Siebert, 2005) Similarly, a number of legislations related to the single markets in the European Union have been established and formulated based on German economic policies. The Euro is the common European currency used by most of the countries in the European continent. In this regard, Germany has implemented the usage of same currency in the country, which has resulted in the exposure of more opportunities related to the strengthened economy of Germany in the region. Frankfurt city in the Germany has the European Central Bank, which is responsible for the formulation of monetary policy of the country, which decides the future prospects for the coming years related to the economy of Germany. (Smith, 1994) Addressing domestic structural problems is another major concern of the German government, which has been agreed and encouraged by most of the German and the foreign experts in the region. In the year 2003, the labor market was deregulated by the gradual steps of German government. In this way, high unemployment rate was tackled in an effective manner. In the West Germany, more than seven percent of fall was observed in the unemployment rate in the country, which was the visible fact of deregulation of the labor market. However, there is still a huge room for improvement in the eastern part of Germany, which has an employment rate of more than fourteen percent in the region. (Scott, 2002) However, the German government is playing a vital role in the addressing of different issues related to the economy of Germany. For instance, high non-wage labor costs have also been addressed by the government with the help of implementation of different policies related to it. Many businesses were burdened due to the imposition of bureaucratic parameters in the past, which was addressed by the present and previous governments during the last decade. Nowadays, it has become quite easy and trouble-free to establish a business in the Germany. New entrepreneurs have been encouraged, especially, in the export sectors of the country. In the result, a major and significant improvement can be observed in the economy of Germany, which is very much export-oriented in nature. (Siebert, 2005) In terms of facts, nine percent of growth was observed in the export year of 2007. In the result, some of the business experts deemed the Germany as the biggest exporter in the world. In the year 2006, more than two percent of growth was observed in the gross domestic product of the country. Moreover, it is estimated that the following years will achieve higher percentage of GDP due to excellent growth in the exports of the country. However, the domestic market of the country is confronting structural problems that can result in some economic issues in the country. Over more than a decade, the labor sector is confronting stagnant wages, which is one of the crucial causes behind the weakness of the domestic market in Germany. In Germany, reunification is financed with the contributions of social insurance companies. Since the 1990s, high wage demands are not observed in unions in the Germany, which has resulted in the conservation of competitiveness among the German workers. Between the years 1990 to 2005, two percent of decline was observed in the net income on an average in Germany, according to the Federal-Statistical Office of the country. However, wage demands from the unions have been raised significantly, as compared with the abovementioned union demands. In the year 2004, GDP of Germany was contributed by forestry, mining, and agriculture sector at a very lesser extent, as compared to the other sectors in the country. Approximately two percent of German population was given employment in the abovementioned sectors. The eastern states of the country have reported to observe a great reduction in the employment rate. After the reunification process, more than seventy percent of workers in the agricultural sector were declined. However, domestic production in the agricultural sector resulted in the fulfillment of more than ninety percent of dietary and food requirements of the country’s population. In the European Union, the agricultural production is being lead by Germany, which has been followed by Italy and France in the European continent. In this regard, wheat, barley, cabbages, and potatoes are some of the major agricultural products in Germany.
