Ecosystem, Temperate Forests Essay Example | Topics and Well Written Essays - 2000 words

Ecosystem, Temperate Forests - Essay Example The animals that live in this type of forest generally include squirrels, rabbits, skunks, birds, deer, mountain lion, bobcat, timber wolf, fox, bears, foxes and other wildcats although most of the larger predators have been killed off or displaced by the human population. The climate goes through well-defined seasonal changes, trending toward long warm summers, moderately cold winters and an evenly spread level of precipitation throughout the year, providing the trees and other plants with sufficient moisture year round for growth while not drowning them. This seasonal shift causes the trees to drop their leaves in the fall, becoming dormant in the winter, only waking in the spring with a new crop of fresh leaves. The process of dropping the old leaves in the fall results in the brilliantly colorful displays of reds, oranges and yellows that characterize this time of year. Many other plants in the temperate forest will also go dormant during the colder months of the year and many of the animals devote their summers preparing for a winter hibernation period. These types of trees require a high level of soil fertility to grow, requiring soils high in nutrients for the development of a new crop of leaves every year. The annual drop of leaves in the fall provide many of these nutrients as they begin to decay and the leaf litter covering the forest floor also serves to reduce the amount of runoff during spring rains, allowing more of the precious nutrients to remain where the tree roots can get them. Where the soil nutrients are reduced in areas such as the more weathered soils of the Southwest or the sandy soils of coastal plains, the trees are characterized by less showy species with narrower leaves or pines. Isolation of these forests leads to a prevalence of only a few types of tree species and a specialized set of characteristics among the animal-life, such as a dominance of black bears in one region and brown bears in another,

Risk Management Essay Example | Topics and Well Written Essays - 1500 words

Risk Management - Essay Example To do this, the airline embarks on several risk management processes. It is not surprising therefore that for all but the second year of operation Emirates Airlines have recorded profits and growth that always span above 20% (CNN Money, 2005). The airline has recorded a profit every year, except the second, and growth has never fallen below 20% a year. In its first 11 years, it doubled in size every 3.5 years, and has every four years since Current Risk Management Process In the view of Tatum (2011), Risk management is a logical process or approach that seeks to eliminate or at least minimize the level of risk associated with a business operation. Kolakowski (2011) posits that â€Å"risk management is concerned with identifying and measuring the risks faced by the firm.† This makes risk management more of a preventive venture than a curative one. In light of this, the Risk Management Magazine (2011) argues that, most airlines have their risk management undertaken by the intern al audit department. Risk management undertaken by companies varies in scope. Some of the commonest identified scopes of risk management include financial risk and field risk. With particular emphasis on the Emirates Airlines and other aviation services, special emphasis are laid on risk associated with staff and customer safety of customers and staff when talking about risk management. Commenting on a typically workable risk management model for airlines, the Risk Management Magazine (2006) outlines nine areas that airlines could look out for in their risk management exercises. These nines models are â€Å"station size, last audit date, last management change, prior audit report rating, compliance with submitting inventory reports, promptness of remitting funds, promptness of submitting sales reports, magnitude of unreported sales (passengers flown for which the ticket sale was not located), and magnitude of discrepancies with local disbursements† (Goepfert, 2006). Still wri ting on management process for airlines, the International Air Transport Association (2010) outlines areas that airlines may consider in their risk management efforts. According to the association, â€Å"Crew fatigue has typically been controlled by a simple set of prescriptive rules concerning flight time limitations (FTL) and flight duty limitations (FDL).† These model, when carefully followed by airlines guarantees financial returns as well as employee and customer safety. Such safety assured among customer also goes a long way to promote a continued business relations with the airline and invariable ensures profitability for the company. Risk Management Problems Like in every other human endeavor, undertaking a useful measure towards the growth of a company does not come easily. In an attempt to ensuring risk management, there certain challenges that the management of Emirates Airline encounters. First and foremost, there is the problem of defining potential risk. Brodzin ski (2006) notes that the definition to a risk too general. This is to say that in an organization such as an airline where there are certainly many managers in charge of the risk management business of the organization, coming to a consensus about what to include in the risk management plan of the organization always becomes the first and most challenging task. This is because what may seem to be a potential risk to manager ‘A’ may not seem a risk to manager ‘B’. It should however take the identification of a problem before any further action on

E-Business , E-Commerce and Information System Case Study

E-Business , E-Commerce and Information System - Case Study Example ips with the customers and the development of a better website will allow PharmQuip to gather useful customer data and retain the customers’ loyalty. The global healthcare equipment industry is anticipated to grow around 5% more till the year 2012. Therefore this is the best opportunity for the company to go global and increase its market share. The developing countries such as Pakistan, India and Malaysia are the most attractive markets because these markets are not concentrated, hence, the demand for healthcare equipment for the disabled will be much higher than in developed countries. NGOs have played another role in creating demand for healthcare equipment as 1500 jobs were created in India in 2005 for the handicaps. The physically challenged individuals who go to jobs or are living alone are the main target segment for PharQuip. Although the international expansion looks very attractive at first glance but it presents a number of issues. As the PharmQuip business will ent er the global arena, it will require more ICT resources and streamlining of the current processes to meet the demand of international healthcare retailers and chemists. The company will need to employ more security measures to enhance the current payment system for its B2B customers. Security of customer data and supplier information will also be needed and will require significant expenditure when the company goes global. A higher budget will be required to advertise and for the promotional strategy to be implemented in all the countries where the company will operate. The single greatest risk that the company faces is from the changes in technologies and introduction of lower cost healthcare equipment. New regulatory requirements can be introduced in the countries which can harm the business. Other risks are the changes in the market dynamics, introduction of alternatives to healthcare equipments and breakthroughs in biotechnologies which can cure the physical disabilities of the

Hyperlipdemia an new treatments with statin medications Essay

Hyperlipdemia an new treatments with statin medications - Essay Example The treatments at West of Scotland Coronary Prevention Study (WOSCOPS – 1995) included 6596 men. The studies proved hugely successful; the all-cause mortality was reduced by 22% (Reamy, 1995). Such results from WOSCOPS and other accompanying studies lead to the commonplace practice of using statin therapy for acute ischemia (Reamy, 1995). It has been proven that synthetic statins such as rosuvastatin and atorvastatin decrease LDL levels. A study showed results of using intensive statin treatment on atherosclerotic plaque burden; the LDL cholesterol level dropped from â€Å"130mg/dl to post treatment level of 60.8mg/dl with 40mg/day rosuvastatin† (Reamy, 1995, p. 8). Other studies have also confirmed that statins are particularly useful for hypercholesterolemia in older patients. The curing action of statin was regardless of the previous levels of serum lipids, gender or age (Aronow, 2006). National Cholesterol Education Program (NCEP) III guidelines suggest that in high-risk patients low density lipoprotein (LDL) level of less than70mg/dl is a rational treatment strategy (Aronow, 2006). This strategy has nothing to do with the age of the patient. In case of a high risk patient with hypertriglyceridemia (low serum high density lipoprotein cholesterol), a combination of nicotinic acid or fibrate with any drug that has the property of lowering LDL cholesterol can be effective (Aronow, 2006). Moderately high-risk patients can be effectively treated with serum LDL cholesterol but the amount should be decreased to less than 100 mg/dl and this level of LDL cholesterol needs to be dropped further (30% to 40%) in case the patient is under LDL cholesterol drug therapy (Aronow, 2006). Despite remarkable lab results in treating hyperlipidemia there have been complications recorded with statin treatment. A study conducted in United Kingdom showed that hyperlipidemia patients treated with statin showed the likelihood of suffering

Patient compliance in English hospital Essay Example | Topics and Well Written Essays - 750 words

Patient compliance in English hospital - Essay Example To summarize those earlier studies, all of them suggest, for obtaining the best results, imaging be done on naturally filled or empty bladders. For those protocols that require filled bladders prior to imaging, ensuring reproducibility in bladder filling becomes vital. The patient is usually informed to have a comfortably full bladder. Put simply, the patient is asked to comply with the prognosis program. However, when the patient voids the bladder without informing the medical personnel, a situation of non-compliance arises, resulting in errors in imaging. Such errors more often than not are compounded by variations in the interpretation of the data. Patient non-compliance in the form of reluctance to agree for evaluation and treatment owing to significant distress, urological symptoms or erectile functions is now a documented aspect of PC (da Silva et al., 1996, p77; Roth et al., 1998, p1908). Whereas Roth et al., report the development of an acceptable approach for rapid screening for distress in PC patients; da Silva et al., recommend that Quality of Life (QoL) assessment be made mandatory to increase participation and compliance rates in future studies that consider QoL to be an important study end point. When patient non-compliance significantly affects the medical interventions, one good strategy of overcoming the same would involve checking on the findings of researchers working on diseases other than PC wherein a similar requirement of having a reproducible bladder volume exists, how those researchers overcame the same and extrapolating those findings to PC. To begin with, usage of frequency volume charts (FV charts) is, perhaps, a better option. Abrams et al., (1996, p53) suggest keeping FV charts for seven days essentially to cover both work and leisure periods. They also propose computerization of the FV charts as an attractive option. Similarly, based on the results obtained in a pair of related studies, Rabin et al., (1996a, p806; 1996b, p34) report greater patient compliance when an electronic voiding diary is maintained in comparison to traditional methods. In a study involving 81 women with urinary incontinence, Jorgensen et al., (1987, p42) advise the usage of one-hour p ad-weighing test, which was found to be practical and useful in quantifying the degree of leakage. Although, PC never affects women, extrapolating the observations might improve patient compliance in PC management. Continuing the discussion on similar lines, despite using the above-mentioned remedial measures, it is possible that the patients might not comply or perhaps owing to various reasons, while waiting for treatment, might void early without informing the medical personnel. This situation makes the development of strategies that do not rely on bladder volume imperative. In other words, the best option would be to implement those protocols that are independent of the 'status' of the bladder. In the absence or non-availability of such protocols, the observations of Faithfull et al., (2001, p1864) are significant. In a

Econ 4020 reaction 12-13 - Term Paper Example However, the total nation debt has kept on fluctuating with different administration implementing significantly different economic policies. In 1919, the participation of the USA in the World War I escalated the total national debt from $6 billion to slightly above $27 billion. The period marking 1920s was characterized by increased levels of private sector spending. As a result, the government generated excess revenue that lead to reduction of the national debt to $16.9 billion. Rate of unemployment also reduced drastically; the nation almost achieved full employment. Unfortunate, in 1929, another great recession invaded the economy as the private spending started to decline. The rate of unemployment too increased (Davidson, 2010). The total national debt continued to increase and by 1936, its ratio to GDP was approximately 4:6. Notably, irrespective of the high debts the USA economy still grew significantly. The period marking World War II (1941-1945), the USA government expenditure drastically increased due to the massive funding of the war. What is interesting is that while the total national debt increased by over 500%, the GDP also doubled. It is recorded that the period that marked the ending of World War I saw each American household have improved standards of living. There was not negative effect of the war as was speculated. The lesion learnt from the historical economic review of the USA is that there should not be fear in spending huge amount of money that results into high debts. The theoretical evidence provided in this paper justifies that the USA economy mostly thrives in times of recession and great depression. Keynes theory suggests that spenders (government) should increase aggregate market demand through spending heavily. This will go along way into creating more job opportunity and at the same time generating additional profits that can be reinvested to grow the economy (Davidson, 2010). The idea is

Hydrogen vehicles Essay Example for Free

Hydrogen vehicles Essay Introduction There are many debates that are advocating for a proper implementation of transport systems, involving greatly upgraded sea transport, conversion of freight industry away from the road network. It is therefore possible for a company to reduce greenhouse gas for the benefit of the environment, through the adaptation of these transport systems. The debates also advocates for the use of hydrogen fuelled cars. This kind of vehicles use hydrogen gas as their powering tool and is considered the safest to the environment. Hydrogen gas cars are said to be somehow expensive, and technologically complex but with great investments companies can be able to utilise them effectively and help reduce the greenhouse gases. Most automobile companies are beginning to use these types of cars with a vision of minimizing costs, especially given the fact that fuel prices are even getting more expensive. Since fuel prices are becoming part of the company’s concerns, there is a need for the companies to effectively seek to have their transport systems to become compliant with the policies in the motor industry sector. So far, hydrogen cars are therefore increasingly being sought after as a matter of commitment by the companies. Discussion The hydrogen is normally derived from the renewable or non- renewable sources, where it is thereafter used on a daily basis. its sources are best known to be solar, water, wind and nuclear powers, though it is found that many vehicles using hydrogen as their source of energy tend to be less polluting the environment than those using gasoline and diesel, this is because, the used hydrogen fuel cells has a less production of carbon dioxide than normal combustion engines. Hydrogen is understood as the lightest fuel that appears in a gaseous state, operated at an atmospheric pressure and an ambient temperature containing a low level of carbon gases such as carbon dioxide and carbon monoxide, this gas is normally stored under a storage system which allows it to be stored as compressed hydrogen, liquid hydrogen in the materials such as the metal hydrides. The reason for this invention is that these vehicles are found to be producing no air pollutants, but instead they only emit heat. It is basically considered as an alternative fuel in vehicles due to its mode of creation that is, it can be made from a number of resources and its characteristics of allowing a clean-burning procedure. The production of this gas has been proposed to be carrying various advantages such as; enabling a stronger national energy security, it also brings about a reduction on the green house gas emissions thus allowing an improvement in the quality of the environmental air, and the other advantage is that of enhancing an increase in the energy efficiency in particular countries. In this case, we find that the United States had a record of 200 hydrogen powered vehicle as in the month of April 2007, these vehicles are based in California, they are normally those cars that run at a high speed, which have been said to be already running on the hydrogen fuel, this vehicles include buses, submarines aeroplanes and also rockets. Though this invention is not yet available in most motor markets, this invention is being established various vehicle fleets an example of this is that of the Honda which is widely known as a light duty vehicles. The United State is said to be concentrating on the invention of more hydrogen vehicles that are meant to cover the whole transport sector in the nation by bringing up more hydrogen refueling stations, this activity is conducted by Department of Energys FreedomCAR, Vehicle expertise and the (HFCIT) the Hydrogen, Fuel Cells, and Infrastructure Technologies Programs, which are said to have developed to be conducting supervision on the performance of the fuel cell vehicles and also sustaining the hydrogen transportation. Under this development we find that the State is trying hard to cut off its dependency on the oil from the Middle East whereby, we see that it has more plans to transform its oil system and start depending on the fuel resulting from hydrogen which carry advantage of not pollute the environment. According to research, it is reported that 95% of the transportation industry depends on hydrogen, under which 65% is used for transportation. Many scientists argue that this invention will take long before it is accepted by the transportation sector, but many companies are found to be investing in the hydrogen vehicle invention. An example is the Ford company which has come up with a plan of launching hybrid electric powered vehicles, this vehicles are meant to act as a solution to energy conservation that are therefore likely to be replaced by the hydrogen vehicles. Conclusion A lot has been said about the market of the hydrogen vehicles, many argue that this invention will take along time to be accepted in the market but we see that there are many governments and the motor industries, are for the idea of using the hydrogen fuel, whereby they have seen coming up with various programs which will implement the invention of these vehicles, thus overcoming the technical and cost barriers accruing in the invention.
