Fuel cells - Research Paper Example The fuel cell also comprises of an electrolyte which functions to transfer the electrically charged components across electrodes. According to the University of Stathclyde Engineering (2015), fuel cells convert the energy from convectional fuels directly into direct current electrical energy. This results in added advantages in the use of fuel cells during the production of electricity. The major advantages associated with the use of fuel cells in the production of electricity include high efficiency, reliability and responsivity levels, low production of emissions, flexible use of fuels, flexibility in the size and application of the fuel cells, a longer life and the quiet mode of operation. In regard to high efficiency levels, fuel cells have been established to be better efficient due to lack of thermodynamic laws known to limit Carnot Cycle efficiencies. Theoretically, fuel cells can attain efficiency levels of 83% which is however lower in practice and stands at 50%. The operation mechanism of fuel cells operation ensures increased efficacy due to the lack of an intermediate conversion into heat that is the case with conventional power schemes. Fuel cells have also been established to attain full power of operation with half an hour and their high responsivity (Fuel Cells, 2015). With the use of fuel cells in the production of electricity, only a quester of th e maintenance procedures currently used in convectional power production techniques is required. Apart from the preferred fuel for use in fuel cells which is hydrogen, several other alternatives are present including biogas, coal, propane, methanol, ethanol, petroleum among others. This presents an increased flexibility in fuel requirements and its lack of pollution and noise disturbance increases its suitability as a power production method. Following the flexibility in fuel requirements for use in the production of power using a fuel

CASE STUDY - Essay Example Although the quotation given by him was $200,000 higher than what Frank wanted, they agreed to proceed with agreement pending negotiations (Crawford 2012 p.57). Early January the following year, Frank sent Jack from Boston to St. Paul in order to confer with the EMFs superintendent. Byers was identified as the final superintendent during the job, after meeting Byers; Jack went ahead as instructed to assess labor situation. In addition, the most important deal was to meet Bye and the prospective subcontractor, Elnicky and give him quotation that indicated the reduction of the initial bid and possibly got the job started. Frank had given Jack quotation prepared by Sullivan, although he had not seen the initial contract for the job. This was certainly the greatest error that happened ahead of the unfolding legal debate. On 22nd January, Jack made the first visit to the Midwest office. During the hearing, he noted that it was the first time he was encountering Jack, and he had identified himself as part of Sullivan team. In what remains a legal argument, Jack allegedly had claimed he had "a piece of it" implying he suggested that he was among the owners of Sullivan. Although Jack denied vehemently, Elnicky admits that he did not bother to ask the official position of Jack within the Sullivan neither did he request for a formal written document (Crawford 2012 p.59). Besides, what caused legal controversy is the fact that he testified that Jack had no objection when he suggested that he wanted to take over the entire job from Sullivan. Besides, he agreed to get a copy of the prime contract to the Midwest in preparation for a takeover. On 23rd Tuesday, a historic event happened when Jack availed the prime contract copy from Sullivan and handed it over to him. On 24th January, Jack made a call informing Frank the ongoing discussion with Midwest, a decision that Frank disagreed since EMF wanted Sullivan in the job. Just before Jack left for

History of Management in Criminal Justice Agencies Essay

History of Management in Criminal Justice Agencies - Essay Example e way the United States criminal justice system has been managed over the past few decades, with former English customs and laws playing a significant role in influencing the contemporary system (Randolph, 2005). The criminal justice system includes parole and probation officers, correction officers, court officers, investigators and line officers. In the early days of the English law enforcement instituted by Alfred the Great, police forces were formed by loyal families who patrolled their regions. They appointed their own leaders, known as reeves, to oversee and coordinate the wider alliances (Friedman, 1993). The reeves later came to be known as sheriffs. To ensure the loyalty of the sheriffs, the power of appointing them was taken over by William the conqueror when he came into power. In the early 18th century, the system established by William the conqueror was borrowed by Philadelphia, Boston and New York with each having 10 official patrol areas (Randolph, 2005). The 19th cent ury industrialization and population growth brought about the need for police departments in municipals. Although New York and Philadelphia had 24 hour police force in service by 1830, some counties still operate under the sheriff system today. The difference is that the sheriffs are not appointed through local governments, but rather elected by citizens. Today, managers within the criminal justice system are knowledgeable in security, police and disaster management fields. Within the judiciary, before the revolution, American courts followed laws that Great Britain had handed down to them. However, the settlers and colonists later rejected the English laws because they did not grant them equal rights as Englishmen under The Great Charter of the Liberties of England (Friedman, 1993). They rejected attempts to be governed by the English Parliament from overseas yet they were not accorded representation. The subsequent rebellion ended in the American Revolution. With the adoption of the

Managing Homeland Security - Essay Example Emergency managers, in their pursuit of tackling critical problems, need to make the best use of available resources, and act efficiently during disaster situations. Although the role of an emergency manager is magnified only during problematic conditions, his work is nevertheless an on-going process. The department of emergency management is required to prepare in advance for potential disasters, respond effectively during disasters, and ensure the well-being and settlement of residents after the disasters are over. Emergency Management departments try their best to make sure that the opportunity cost of emergency management actions such as emergency preparedness and hazard are less than the long-term losses incurred from maximum credible disasters. As the Emergency Management Coordinator, it is my job to have proper hazard and vulnerability analysis of the city conducted frequently, and facilitate training to task-forces, as well as citizens to ensure that the city is prepared to handle catastrophic situations at all times. These trainings can be done in the form physical exercises and drills, or dissemination of safety information. Also included as part of my duty is the creation of new positions and policies for the innovative and initiated minds, redefining responsibilities and considering budget requirements. Moreover, I shall endeavour to form coalitions with banks, insurance companies, local government agencies, and other forms of community groups so as to reduce disaster losses to the city and its residents. When a situation arises, it is important that emergency managers work in collaboration with other public service and safety departments like the police force, fire department and paramedics. To achieve unanimity of purpose, an emergency manager can work towards ensuring that public safety departments are in frequent contact with each other, and information flows through them without barriers of
