Compressed Natural Gas (CNG) as Transportation Fuel

Compressed Natural Gas (CNG) as Transportation Fuel Use of compressed natural gas, or CNG, as an alternative vehicle fuel is growing in significance with many city-owned fleets converting to the fuel. Though not renewable, CNG still holds some advantages over other fossil fuels such as petroleum. Here are five quick takeaways to help you understand the use of CNG as a transportation fuel. The Safety of Compressed Natural Gas One of the first questions raised about the use of CNG in vehicles is safety. Maybe its because of its stealth persona as an odorless, colorless gas, but natural gas tends to strike fear into people over worries of explosion or related catastrophes. Yet, compressed natural gas has actually grown in popularity because it is seen, by those who actually know the facts, as a safe fuel choice. In fact, its not too hard to see why CNG is actually considered to be safer than gasoline. Natural gas is lighter than air, so a spill wont puddle the way gasoline will nor will it sink close to the ground like propane. Instead, CNG rises into the air and then dissipates in the atmosphere. In addition, CNG has a higher ignition temperature. In other words, its harder to ignite. Finally, CNG storage systems are much stronger than the typical gasoline tank found on a car or truck. Where CNG Comes From So where does CNG come from? The answer lies deep beneath your feet because natural gas is an organic compound, deposited deep within the earth. Although considered an alternative fuel, unlike many of its counterparts, natural gas is a fossil fuel and is primarily methane comprised of hydrogen and carbon. It is estimated that there are enough reachable deposits of natural gas below the Earths surface to last long after stores of petroleum have been depleted, though the supply is not infinite by any stretch. In addition, there is controversy over the environmental impact of fracking, the method used to reach natural gas deposits lying deeper under the Earths surface. Using Natural Gas For Vehicles The process of allowing natural gas to be used by a vehicle begins with natural gas being compressed and entering the vehicle through the natural gas dispenser or other filling means. From there, it goes directly into high-pressure cylinders located somewhere on the vehicle. When the car is accelerated, CNG leaves this on-board storage cylinder, passes along the fuel line and then enter the engine compartment where it enters the regulator which reduces the pressure from as high as 3,600 psi down to atmospheric pressure. A natural gas solenoid valve enables natural gas to move from the regulator into the gas mixer or fuel injectors. Mixed with air, natural gas flows on through the carburetor or the fuel injection system and from there, enters the engines combustion chambers. Compressed Natural Gas Vehicles Although over 25 automakers produce nearly 100 models of natural gas vehicles and engines for the U.S. market, the only CNG vehicle available for personal consumer use is made by Honda. CNGs market in the U.S. has been primarily for transit buses, where over 10,000 are currently used in the country. Its estimated that about one in five buses currently on order are CNG vehicles. But numbers elsewhere around the world are much high with an estimated 7.5 million natural gas vehicles on the streets globally. Thats twice what there was as recently as 2003. Its forecasted that by 2020, more than 65 million NGVs will be in use worldwide. CNG is Cost Effective CNG is also economically attractive. The U.S. Department of Energy has reported that the average nationwide price of a gallon of gas equivalent of CNG was as low as $2.04 per gallon in recent years. Prices are even lower in some areas of the country. Local and state governments have reported having their fuel bills cut in half by increasing the use of natural gas vehicles.

Transformational Leadership Essay Example | Topics and Well Written Essays - 2000 words - 1

Transformational Leadership - Essay Example Some of the factors were the rapid changes in technology, an increase in the circulation of products from recently industrialized nations, increased competitiveness among the competitors, pricing strategy in the Organization of Petroleum Exporting Countries (OPEC) being volatile, and changing market structures led to a strong, volatile and competitive atmosphere in which important changes in the organization were crucial. Downsizing and adopting of new types of business agreement were the most common changes carried out. Therefore these changes took their toll on employee empowerment and satisfaction. This broke the old social agreement that had long term employment and in exchange get the employee's loyalty (Griffin 2003, p. 1). Secondly, in the 1970s, we had the contingency theory on leadership. The theory on leadership was established in research of behaviors, character, and circumstances and did not account for several untypical features in leaders (Simic 1998, p. 50). These are the fact tendencies that led to the realization of the theory of transformation.Odom and Green (2003), based on research and the analysis of a number of legal cases, claim that when the concept of transformational leadership is used in ethical dilemmas that managers face there is less litigation and better moral results than if the transactional approach to values that is common was used. Within academic surroundings, as a result of transformational leadership, instructors are more likely to work together and are perceived.

Learning and teaching assessment - Essay Example It is obvious that for such a sensitive procedure, my students have the basics of clinical studies covered. The most common way of classifying students is to use the visual, auditory and kinesthetic way, otherwise known as the VAK model (Utley, 2010). This model establishes a learner’s preferred mode for learning and processing new information. The VAK model was introduced in the 1920s by the likes of Keller, Orthon, Fernald, Stillman, Gillingham and Montessori (Dreeben-Irimia, 2010). In addition to the VAK model Gaberson and Oermann (2010) add more tools to expand the teaching strategies by including olfactory and emotionally experimental methods that help children who don’t benefit a great deal from didactic methods, learn. Although there are three main categories for students (refer to the VAK model) however, within the visual class Ryan at al. (2011) further divide the class into two subclasses; the ‘verbal visual’ and the ‘spatial visual’. The verbal visual students are those that best learn when the information is ‘written down’. The spatial visual students prefer solely the marvel of the visual; graphs, charts, diagrams etc. Such learners are generally good with faces and have good sense of direction (Hill & Howlett, 2012). Auditory students perform really well in brainstorming sessions. It is almost a ideal way to absorb, process and take part in the creative process (Spencer & Vavra, 2009). These learners can be taught better when the same idea is rephrased in several different ways (Lauwers & Swisher, 2010). The whole idea behind using the VAK model is not to isolate students based on their preferred teaching styles. It is a mere recognition that some students prefer one method over another while learning. In real practice, the VAK model is more popular with the more vulnerable exceptional learners (Zhang et al., 2012). The teacher can affirm if a student prefers

Brain Tissue Oxygenation Monitoring System and Subsequent Nursing Inter

According to the Centers for Disease Control and Prevention (CDC) (2010), approximately 1.7 million individuals are diagnosed with a traumatic brain injury (TBI). Within the medical and allied health care professions, various definitions are utilized to define what constitutes a TBI (Abelson-Mitchell, 2007). Despite such various definitions, a TBI essentially describes any form of trauma directed at the brain and its surrounding anatomical structures (Abelson-Mitchell, 2007). As with most injuries, a TBI is graded as mild, moderate, or severe; however, in contrast to most severe injuries, a severe TBI can detrimentally affect an individual’s motor and cognitive functioning (Abelson-Mitchell, 2007; CDC, 2010). Children and adolescents sustain approximately half of all diagnosed traumatic brain injuries (CDC, 2010). According to a literature review study conducted by registered nurse, Abelson-Mitchell (2007), adolescents, between 15 to 18 years of age, are the most vulnerable of obtaining a TBI. Such vulnerability has been linked to the continued development of the brain and the number of associated motor vehicle accidents and sport-related injuries (CDC, 2010). Within the last 20 years, the number of adolescents participating in high school sports has dramatically increased (Kerr, Collins, Fields, & Cornstock, 2010). Subsequently, the level of competition within high school sports has considerably increased as well, further causing a rise in aggression and physical contact among these young athletes (Kerr, Collins, Fields, & Cornstock, 2010).

Effects On The Industrial Revolution

ECONOMICALIndustrialization resulted in an increase in population and the happening of urbanization, as a growing number of people moved to urban centres in search of employment. Some individuals became very wealthy, but some lived in horrible conditions. A class of wealthy industrialists, ship owners and merchants conquered, accumulating great wealth, but at the same time the working classes had to live with minimum comforts in overcrowded environments. Children were sent to work in factories, where they were broken and ill-treated. The growth of the Industrial Revolution depended on the ability to transport raw materials and finished goods over long distances.There were three main types of transportation that increased during the Industrial Revolution: waterways, roads, and railroads. Transportation was important because people were starting to live in the West. During this time period, transportation via water was the cheapest way to move heavy products (such as coal and iron). As a result, canals were widened and deepened to allow more boats to pass. Robert Fulton made the first steam-powered engine to power a steamboat, and in 1807 he demonstrated its use by going from New York City to Albany via the Hudson River.His steamboat was able to carry raw materials across the Atlantic Ocean by the mid 1800's. The roads also improved immensely during this time period. Previously, people traveled using animals or by foot, but there were many problems with the conditions of the roads. In 1751, turnpikes were created for easier transportation, especially for the horse-drawn wagons. John Loudon McAdam made â€Å"macadam† road surfaces which consisted of crushed rock in thin layers.Thomas Telford made new foundations in roads with large flat stones. Soon after, roads across America were improved based on these techniques. The closest to trains were horses, commonly used to pull freight cars along rails. In 1801, Richard Trevithick made the first steam locomotive . These improvements on waterways, roads, and railroads all made traveling safer, and it allowed goods to be moved more efficiently.SOCIALWomen experienced large changes in their lifestyle as they took jobs in  domestic service and the textile industries, leaving the agricultural workforce and spending less time in the family home. This period also saw the creation of a middle class that enjoyed the benefits of the new prosperity. People started spending their free time entertaining themselves in theatres, concert halls and sports facilities or enjoying the countryside in long path.The Industrial Revolution was preceded by an agricultural revolution that increased the food supply while decreasing the amount of labor needed. Traditionally, the primary goal of agriculture was to produce enough food to prevent famine. This overwhelming fear of starvation made most farmers very conservative and highly skeptical of change. Poor harvests would lower the supply of food, which would resul t in increased prices. The basic effect of supply and demand was at the center of most of the class conflict in this preindustrial world.Both bad harvests and increased population affected the price of food. High prices increased the wealth of the aristocratic class and led to death and starvation among the peasants; therefore, the primary reason behind most peasant uprisings was the high price of food.POLITICALMost important, however, 19th-century Britain experienced political unrest as the industrialization and urbanization of the country created a need for social and political change. There were increasing demands for improved social welfare, education, labour rights, political rights and equality, as well as for the abolition of the slave trade and changes in the electoral system. As a result, the slave trade was abolished in 1807 and the Great Reform Act was passed by Parliament in 1832. After this Reform Act, manufacturing cities such as Birmingham and Manchester could be repr esented in Parliament for the first time, thereby substantially changing the character of parliamentary politics.The Industrial Revolution brought many changes to Europe but one of the most notable differences is urbanization. Urbanization is the process of people migrating to the cities from farms and the country. Before urbanization and the Industrial Revolution, most people were peasants and lived out in the country. Their occupation was a farmer and they generally just worked from home. However, once the Industrial Revolution started people, people started moving to cities and working in  new factories, increasing urbanization. A reason for this was that because of a surplus of food, the population increased.This supplied more labor which allowed people to start moving to cities instead of staying on the farms. Also more jobs were found in the cities compared to the farms because of new technologies that greatly increased the productivity of farming which cause the demand for farmers to decrease. However, the continuity of this change is that even though farmers were moving out the cities to find jobs, there were still farmers working in the country. Farmers were still needed to produce food for the growing population but there were less of them needed because technology replaced some the need for human labor. Urbanization was certainly a crucial change during the Industrial Revolution but there were still some features that stayed the same.
