How Hybrid Cars Work Essay

A hybrid car is a passenger vehicle that is driven by a hybrid engine, which is any engine that combines two or more sources of power, generally gasoline and electricity. There are two types of gasoline-electric hybrid cars; the parallel hybrid, and the series hybrid. Both use gasoline-electric hybrid technology, but in radically different ways. In a parallel hybrid car, a gasoline engine and an electric motor work together to move the car forward, while in a series hybrid, the gasoline engine either directly powers an electric motor that powers the vehicle, or charges batteries that will power the motor. Both types of hybrids also use a process called regenerative braking to store the kinetic energy generated by brake use in the batteries, which will in turn power the electric motor. Both parallel and series hybrids have small gasoline engines, and produce much less pollution than standard gasoline cars, but also produce much less power – hybrids generally produce between 60-90 horsepower, while the average gasoline engine probably produces about double that. To overcome this power gap, hybrid cars are constructed with ultra lightweight materials like carbon fiber or aluminum. Hybrid cars are also designed to be more aerodynamic than most cars, allowing them to â€Å"slice† through air instead of pushing it out of the way. All these factors combined equate to a super efficient form of car that gets excellent fuel economy and helps the environment by cutting down on pollution.

They provide the power of gas and the cost effectiveness of electric cars. These cars are the highlighted display of what technology from different areas can create when put together into one vehicle. Hybrid cars take some time to understand the functioning process. Start by gaining an understanding for how an engine in a hybrid car works. Function starts by utilizing windings moved by an electromagnetic force. This force occurs when an electric current passes over the motor. When the polarity of the current runs one way, the motor turns one way. As the polarity changes course so does the direction of the motor current. This is different from a traditional gas engine. Here the pistons push the gasoline through the crank which in turn provides power for the wheels to move. This process repeats over and over until the vehicle moves. As the gas pedal is pushed down, gas flows into the system and increases the power of the wheels and pistons. Hybrid cars make use of both the traditional engine and the electric engine. The two forces come together to create a revolutionary car power. As the car begins to move, a computer sensor determines which engine type is more suitable for use at that given moment. In cases of high power, the gas engine is utilized. Likewise, when power levels can be low, the electric engine is utilized. On the electric side of things, as the car comes to a stop, the battery regenerates by conserving energy. As the power drains out of the electric battery, the gas engine takes over until the point that the electric battery can be recharged. It can be hard to determine the difference then between gasoline cars and hybrid cars. When a gasoline car is idle, the gas still runs. When a hybrid car is idle, the motor switches from gas to electric. As the car comes to a stop, the energy is absorbed back into the electrical portion of the battery. The only real drawback to a hybrid car is the weight. In addition to the engine weight there are add-ons that are needed to help the electric engine run smoothly. Outside of this factor, the two engines co-exist smoother than ever in a hybrid car. The end result is a worthwhile vehicle that is environmentally friendly and economical at the same time. There are variations on hybrid car models. A selection of vehicles comes equipped with charge coils that allow California users to replenish electrical battery supply. Others utilize alternative fuel sources such as fuel cells. Despite the setting of the car, an owner can rest assured that it is needed to keep the hybrid running in peak performance condition. Each manufacturer tweaks the basic function process of a hybrid. This is what sets each hybrid apart from each other. Regardless of the individual tweaks the basic premise of a hybrid is the same. Create a car that is cost efficient and environmentally friendly so drivers can do their part to help save the environment.

Ethinicity And American Culture Essay

The treaty of Guadalupe Hidalgo 1850 was signed between the American government and the interim government of the military occupied Mexico which resulted in the end of the Mexican-American War. This was intended to bring peace in the disputed territory and the end result was that Mexico ceded a large territory to the United States and its size was reduced by forty-five percent. The land Mexico ceded to the U. S. is now a number of states: Nevada, Utah, Arizona, and California. The military government in Mexico received fair compensation for the territory. The treaty of Guadalupe paved the way for the way for the immigration of Mexicans especially workers to the U. S. this was necessitated by the United States’ need for labor to develop the newly acquired territory. Immigration patterns have been determined by American manual labor needs. The Immigration Process The immigration of Mexicans to the U. S. began soon after the territory was surrendered, the U. S. government sought labor from Mexico to build the railroad which was to connect all the new territory to the other states. Between 1850 and 1880 the U. S. government brought in 55,000 migrant workers from Mexico into the former Mexican territories to work on the railroad. The government preferred Mexican laborers because they were not entitled to any constitutional protection and they could work for substandard wages in the harsh conditions. The process of immigration began to peak up speed in 1910 when the Mexican revolution took place. After the revolution, more then 50,000 Mexican workers immigrated to the U. S. in search of jobs which they felt were better than those available in their home country. Changes over Time Change in the immigration process began to take shape in 1929 when American citizens massively complained that the illegal workers were taking up their job. The government responded by launching major crackdown on immigrants who did not posses the relevant immigration documents. This resulted in the forceful deportation of over two million Mexican of which about one and a half million had been born in the U. S. this was harsh as those born in the U. S. were therefore citizens by birth. The U. S however found itself in a tight spot when it got in World War II in 1942 which elicited the need for Mexican workers. The U. S. acted quickly to remedy the situation by getting into an agreement with Mexican officials and this was known as the Bracero program. Under the program guest Mexican workers would be allowed to enter the U. S. and provide labor on a temporary basis though they would not be afforded the labor protections accorded to their U. S. counterparts. The program run through out the period of World War II and went on up to 1964 as major Corporations had pulled string to ensure that the laborers continued to work as they wanted to cash in on the cheap labor. Since 1964 there was what has been referred to as an unspoken agreement between the undocumented workers, Corporations and the government. The government has intentionally failed to implement border regulations after being lobbied by major corporations which benefit highly from the labor if the immigrants. Though the agreement has been said to benefit all the parties which is utterly false as the immigrant workers are subjected to poor living conditions, are paid substandard wages and do not enjoy the protection of labor unions or practices. In 1986 three million undocumented Mexican-American workers were granted amnesty by the Reagan administration and this consequently made them subject to human rights protections, (Borjas & National Bureau of Economic Research, 2007). Effect on Chicano Movement The Chicano movement was vastly affected by the immigration of undocumented as they were not officially recognized by the U. S. government. This meant that they did not enjoy constitutional protection like other American citizen and the movement’s job was harder as attempts at demanding for rights resulted in deportation. Mexican workers therefore did not seek the help of the movement as they fear that its intervention would result of their deportation, (Rosales, 2000). Conclusion The immigration of Mexican to the U. S. began with the need by the U. S. government to have cheap labor for building of a railroad through the territory acquired from Mexico in 1850. The immigration pattern has however been tied only to the manual labor needs of the U. S. as the government allows entry of undocumented Mexican workers when they are in dire need of cheap manual labor like during World War II. The pattern is also evident from the push and pull debate that rages on the undocumented workers. Reference Borjas, G. J. & National Bureau of Economic Research. (2007).

Houston: Arte Publico Press. ESSAY TWO Some historians describe the Civil Rights Movement as a two-phase process of a southern movement to guarantee basic human rights and a northern movement focused on economic and social inequalities. In an essay, which incorporates lecture, readings and class discussion analyze this process. Introduction The Civil Rights Movement sought reform in the way the American society treated African Americans and it sought to change the perception. The movement originated in the urban areas of the south after large numbers of African Americans migrated from the rural areas and this was after the abolishment of slavery. The American Civil Rights Movement faced a number of challenges in its quest for equal civil rights for African Americans and other minority groups. This came in the form of legislation which promoted the injustices committed against African Americans by white Americans. The movement was therefore forced to employ different strategies and tactics so as to have its voice and that of its people heard. The movement suffered major losses in the road to the eventual attainment of those rights. The Civil Rights Movement refers to a reform movement of African Americans which sought to attain equal civil rights under the law for all people. It sought to have the abolishment of both public and private acts of discrimination and segregation against African Americans. The movement is said to have originated in the southern urban areas when millions of African Americans migrated from rural areas to the urban centers of the south. The Civil Rights Movement employed various strategies which included: nonviolent strikes, civil disobedience, marches, boycotts, protests rallies and â€Å"freedom rides. † The movement therefore focused on disenfranchisement and the Jim Crow laws in the south. The Civil Rights Movement in the south can be said to have been the most intense as it was in the south that African Americans faced the greatest resistance to their attempts to struggle for equal rights. The south had become the most notorious when it came to the suppression of rights of African Americans. The laws in the south permitted or required four acts of discrimination against African Americans. They included voter suppression or disfranchisement, denial of economic opportunities, private acts and mass racial violence and racial segregation which was first upheld by the U. S. Supreme Court decision in 1896 in the case of Plessy v. Ferguson. It was also in the south that most of the milestone events in the civil rights movement took place in the south which included the: Martin Luther king Jr. assassination, march on Selma, Alabama, Mississippi freedom summer and the Montgomery bus boycott. The south was also home of some of the most important literature to come out of the Civil Rights Movement like Dr. King’s Letter from Birmingham jail. It also home to important Civil Rights Movement landmarks like the Martin Luther King Jr. National Historical Site. The latter also house a museum which chronicles the American Civil Rights Movement. The challenges of the movement in south emanated from the legislature passing of the Jim Crow laws which legalized segregation in all public facilities. This law meant that African Americans and other non-white citizens were designated different facilities this includes: lavatories, buses, restaurants, housing establishments among others. These went on to be adopted by most local government across the country and this turned to be a major challenge to the Civil Rights Movement. It was the successes of the Civil Rights Movement in the south which made life better for African Americans all over the United States. The civil rights movement culminated in the passing of the Civil Rights Act in 1964 and the Voting Rights Act in 1965 but of which were a clear symbol of the success of the Civil Rights Movement, (Williams & Bond, 1988). Conclusion Despite the major challenges the American civil Rights Movement faced, it managed to succeed in its cause because of its strategies, sacrifices and it resilience. Some of the sacrifices the movement had to contend with included the loss of one of its leaders, Dr. Martin Luther King Jr. who was assassinated. Though this was a major blow the movement managed to remain resilient and it was rewarded with the passing of the Civil Rights Act and the Voting Rights Act in 1964 and 1965 respectively. The fact that most of the Civil Rights Movement events took place in the south does not mean that the northern part of the country was not involved as activities like the march on Washington took place in the north. The march was the venue for famous â€Å"I Have a Dream† speech by Dr. Martin Luther King. The civil rights movement therefore came along way to achieve success. Reference Williams, J. , & Bond, J.

The Shoemaker and the Tea Party essays

The Shoemaker and the Tea Party essays Alfred Youngs The Shoemaker and the Tea Party, takes readers to a whole side of the American Revolution not emphasized in history books. Young writes in his book of individuals omitted and the events that shaped beginning of the Revolution and the United States as it is today. Some of the biggest points stressed in HIS 315K that coincide with the book are the sugar-coating of facts to make them more appealing, the credibility of history tellers, and the problems that resulted in the consequences that shaped history. The story being told revolves around the life of a Bostonian shoemaker named George Robert Twelves Hewes, whose accomplishments preceding the Revolution were overshadowed by the heroification of more appropriate figures such as John Hancock and Samuel Adams. Paul Revere, famous for his midnight ride, was a man who took pride in his job as a blacksmith. It is a shame that history only gave Revere credit for his message that the British are coming! and was oblivious to his life accomplishments as a man and a skilled artisan. Although only a shoemaker, Hewes actions proved him to be an honest and dignified man. Hewes grew up poor; his meager possessions helped him learn to deal with tough situations. During the destruction of the tea, he was worked alongside great political figures like Hancock and Adams as equals, doing what they believed to be righteous and fair. Going into the matter, Hewes followed under others, but ended up leading one the groups in taking over a ship and f acilitating the dumping of the tea into Griffins Wharf. Hewes also risked his life to save a boy from a beating by John Malcolm, which resulted in Malcolms tar and feathering. Even after being struck in the head by Malcolm, Hewes tried to save him from the mob, but was unsuccessful. A major theme of the book is the gradual progression of the lower classes creeping towards equality with the...

Learn About the Organ Systems in the Human Body

Learn About the Organ Systems in the Human Body The human body is made up of several organ systems that work together as one unit. In the pyramid  of  life  that organizes all of the elements of life into categories, organ systems are nested between an organism and its organs. Organ systems  are the groups of organs that are within an organism. Ten major organ systems of the human body are listed below along with the major organs or structures that are associated with each system. Each system depends on the others, either directly or indirectly, to keep the body functioning normally. Once you a feeling confident in your knowledge of the organ system, try a simple quiz  to test yourself. Circulatory System Dorling Kindersley / Getty Images The main function of the circulatory system is to transport nutrients and gasses to cells and tissues throughout the body. This is accomplished by the circulation of blood. Two components of this system are the cardiovascular and lymphatic systems. The  cardiovascular  system is comprised of the heart,  blood, and  blood vessels. The beating of the heart drives the cardiac cycle which pumps blood throughout the body. The  lymphatic  system is a vascular network of tubules and ducts that collect, filter and return lymph to blood circulation. As a component of the immune system, the lymphatic system produces and circulates immune cells called lymphocytes. The lymphatic organs include the  lymph vessels, lymph nodes, thymus, spleen, and tonsils. Digestive System comotion_design / Getty Images The digestive system breaks down food polymers into smaller molecules to provide energy for the body. Digestive juices and enzymes are secreted to break down the carbohydrates, fat, and protein in food. The primary organs are the mouth, stomach, intestines, and rectum. Other accessory structures include the teeth, tongue, liver, and  pancreas. Endocrine System CHRISTIAN DARKIN / SCIENCE PHOTO LIBRARY / Getty Images The endocrine system regulates vital processes in the body including growth, homeostasis, metabolism, and sexual development. Endocrine organs secrete hormones to regulate body processes. Major  endocrine structures include the  pituitary gland, pineal gland, thymus, ovaries, testes, and  thyroid gland. Integumentary System The integumentary system protects the internal structures of the body from damage, prevents dehydration, stores fat, and produces vitamins and hormones. The structures that support the integumentary system include skin, nails, hair, and sweat glands. Muscular System Oliver Burston / Getty Images The muscular system enables movement through the contraction of muscles. Humans have three types of muscles: heart muscle, smooth muscle, and skeletal muscles.  Skeletal muscle is made up of thousands of cylindrical muscle  fibers. The fibers are bound together by  connective tissue  that is made up of  blood vessels and nerves. Nervous System Science Picture Co / Getty Images The nervous system monitors and coordinates internal organ function and responds to changes in the external environment. The major structures of the nervous system include the  brain,  spinal cord, and  nerves. Reproductive System DEA PICTURE LIBRARY / Getty Images The reproductive system enables the production of offspring through sexual reproduction  between a male and female. The system is comprised of male and female reproductive organs and structures which produce sex cells and ensure the growth and development of offspring. The major male structures include the testes, scrotum, penis, vas deferens, and prostate. The major female structures include the ovaries, uterus, vagina, and mammary glands. Respiratory System LEONELLO CALVETTI / Getty Images The respiratory system provides the body with oxygen via a gas exchange between air from the outside environment and gases in the blood. The major respiratory structures  include the lungs, nose, trachea, and bronchi. Skeletal System SCIEPRO / Getty Images The skeletal system  supports and protects the body while giving it shape and form. The major structures include 206  bones, joints, ligaments, tendons, and cartilage. This system works closely with the muscular system to enable movement. Urinary Excretory System Stocktrek Images / Getty Images The urinary excretory System removes wastes and maintains water balance in the body.

In 1982, a man named Howard Schultz decide to join Starbuck as he was ones impressed by the culture and popularity of Starbucks’ services and by 1990 Starbucks had expanded beyond the borders of Seattle to the rest of the world (Bussing-Burks, 2009, pp. 1-2). 1.1. Evolution of its strategy over time Starbucks strategies have changed over time since it started its operations in the coffee industry. Mr. Schultz, the CEO has changed the culture of its operations from the small shop in Pike place market in 1971 to the now big company that is known all over the world. Starbucks actually changed the manner in which people perceived and drank coffee. Today Starbucks offer their services with Wi-Fi server customers on the sofa as well as on the sub ways which never used to happen back then. With the management of Mr. Schultz, Starbucks expanded so fast and at some point some of its stingy customers abandoned it (Deresky, 2008).

Health Communications Research Paper on Hurricane Katrina Essay

Health Communications Research Paper on Hurricane Katrina - Essay Example Earthquake stroke Kobe Japan a few years ago killing 200,000 people. True, however is the recent ruthless, Hurricane Katrina hit of Louisiana and Mississippi Gulf Coast August 29, as a Category 4 hurricane with sustained winds of 145 mph It flooded 90,000 square miles displacing 400,000 people. 1 The official death toll now stands at 1,302 and the damage estimated from $70 to $130 billion. According to the Federal Emergency Management Agency (FEMA) over one million persons were displaced, and hundreds of thousands remain dispersed throughout the U.S. including some 200,000 people staying in 65,000 rooms in 10,000 hotels or motels nationwide. Additional thousands are reportedly still housed in Texas churches. Forty-three states are now eligible for federal assistance to help meet needs of evacutees. More than 200,000 people also lost their jobs across the affected Gulf region. However, experience from the historical disasters has established a dichotomy between disaster and peoples re silience. People have been able to adapt very first by embarking on reconstruction regardless of the impact. In the wake of Katrina for example resilience has gained a new relevance. Relatively, resilience and catastrophes are two inseparable entities that depend on demographics and the impact of the devastation. Just as some people can fend off traumatic illness while others succumb, not all cities are equally of rebounding from a shock to the system. A person whose health is compromised to begin with, has less chance of recovery than an individual in full health. So too is a city. New Orleans, which already was burdened with huge social and economic problems long before Katrina arrival have played a major role in determining how well the Crescent City will recover from the storm and its aftermath. Urban resilience, moreover, is not necessarily progressive. In spite of the seeming tabular Rasa opportunity a major disaster can offer to correct old errors and put things right, reconstruction tends to favor the status quo. Even if city buildings are toppled, foundations are often reusable and property lines remain. Insurance claims and simple inertia help push landowners to rebuild more or less what they lost. The deep psychological need to see things put quickly back the way they were has also had a positive impact on resiliency and thereof reconstruction. While a disaster can trigger a host of long-term innovations, these tend not to surface in the immediate wake of a catastrophe. Visionary schemes have been the stuff of good times, when people can afford the lu xury of debating possible future. The last thing people want to do in the middle of a disaster is wait around for the minute of a brave new plan to be refined for implementation. When London burned in 1666, Christopher Wren, John Evelyn's and others, full of axial boulevards and capacious plazas; all remained on paper, floated grand schemes. What Londoners returned to instead, was a city that looked and felt much as it did before the conflagration. And while Chicago great fire of 1871 eventually yielded a city of fire-proof masonry buildings as well as the first skyscrapers, the initial reconstruction phase fell back to erecting very kinds of rickety firetraps that caused the catastrophe in the first place. This notion of regressive resilience extends also to a city social order and
