Complete 6 pages APA formatted article: Performance Deterioration of Gas Turbine Engines. It is equally important also to cover the aspects of permanent deterioration (Meher-Homji, Chaker, and Motiwala, 2001). There are several gas turbines utilized in combined cycles, and the recovery of steam generator performance is made.

The use of high-performance gas turbine engines has increased fuel costs making it essential for maintaining high working efficiencies of the engines. It is important to understand the basic design and aerodynamic principles regarding gas turbines. The factors that affect deterioration include the temperature control on the materials, rotor speeds and the stress levels, and the fluid dynamic characteristics that include, choking, dissolution, stall, and infuse. To attain sufficient thermodynamic efficiency, there is a necessary need for heat to be added at high temperatures (Meher-Homji, Chaker, and Motiwala, 2001). Accordingly, there shall be a mechanism for cooling to be included. The cooling characteristics can in turn affect the complete thermal efficiency of the engine. For that reason, the losses that culminate in the cooling flow can have detrimental effects causing a cycle penalty. Thus, several forms of deterioration can alter the cooling flow and the overall working efficiency of the gas turbine.

The compressor can accumulate dust during its working cycles on the field. The dust eventually finds its way into the tiny cooling holes in the hot areas of the blades. This will in turn lead to blade distress due to the impaired cooling caused by the dust blocking the vents of the blades. This gives an example of how performance degradation is linked to the mechanical behavior and consistency of a gas turbine engine. On the other hand, higher firing ratios increase pressure ratios. Accordingly, high-performance gas turbine engines that have high-pressure ratios, cyclic temperatures, tight tip clearances, and stage loadings are more vulnerable to performance deterioration.

research paper on possible career choices in the school system.

Need an research paper on possible career choices in the school system. Needs to be 5 pages. Please no plagiarism. Sweet and Watts (2004) point out that the provision of career guidance services is usually expensive, and it is also limited in terms of access. They also examine the shortcomings that can present themselves when offered only by schools. From their perspective, this should be done with help from external agencies that are well versed with current trends. These factors point to a gap among young people when making-up choices about their careers.

In a report by Caroline St. John-Brooks and the Center for Educational Research and Innovation, it is clear that there is a need to equip young to understand their abilities (Saint, 1995). This is to allow them to have a smooth change over from school to work. It asserts that the counselor’s role is to help an individual make changes according to the changing society and demands.

The purpose of this paper is to inform people about the importance of career guidance. This is aimed at helping career counselors and those involved in the process of career guidance to reach informed decisions about their life. It also offers insights into two careers: curriculum specialist and social work, which are discussed as possible career choices.

Future Implications of 3D Printing.

I will pay for the following article Future Implications of 3D Printing. The work is to be 5 pages with three to five sources, with in-text citations and a reference page. Notably, 3D printing applies in various manufacturing and production industries that include motor vehicle, food, fashion, aerospace, architecture, and health, among other industries. This paper addresses the background information, used materials, different process, and future implications of 3D printing. Printed Car (Strati) and Food Printer (Foodini) are examples of 3D printing.

3D printing relates to additive manufacturing and involves using digital models to design and manufacture a three-dimensional solid product of any shape (Frauenfelder, 2013). 3D printing accommodates variant complex geometries, supports diverse materials, and relies on different processes and applications to develop unique products (Z Corporation, 2005). Indeed, 3D printing enhances the development of early concept models and product prototypes at high speeds, low costs, and using various applications (Cano, 2011). Various companies have adopted 3D printing in their processes. Just like any other innovation, 3D printing underwent a long and involving evolution process, which led to increased efficiency, affordability, flexibility, and diversity of the innovation (Lipson & Kurman, 2013).

3D printing innovation relied on immense contributions from MIT and ZS. Indeed, MIT visionaries sought to establish the fastest and most affordable prototyping in 1993 (Z Corporation, 2009). Some of the MIT visionaries founded Z Corporation in 1994, where they aimed at developing 3D printing to colored, fast, accurate, and affordable document printers (Z Corporation, 2009). The first generation of 3D printing came in 1996 and later evolved to a vivid and multi-color model courtesy of the incorporation of the Z402c and Z406 versions (Z Corporation, 2009). The Second Generation of 3D printing came in 2003 and depicted improved speed, usability, and affordability (Z Corporation, 2009). The Third Generation 3D printing came in 2007 and depicted enhanced office&nbsp.compatibility.

submit a 1250 words paper on the topic Library Navigation Exercise.

Hi, need to submit a 1250 words paper on the topic Library Navigation Exercise. The LCSH lists the standard headings used by most libraries to organize their collection of information. The LCSH is an easy way to find one or more subject search terms that will quickly yield useful sources on your subject. Consult the LCSH with your topic in mind and jot down several search terms that seem promising.

Now that you’ve found subject terms that might help narrow your electronic search down, look on the supplemental “Library of Congress Classification System” handout (below) and find the general subject heading that most accurately reflects your topic. Note the call letters for that topic and go to the corresponding reference section of the library and take a look around (for example: if you are writing about the impact of music on the actions of human beings, you might look at “Music” and find that the call letters that best suit your topic are “ML”). When you seek out that section of the reference material, you will find a variety of possible reference material. Please note that you are going to have to look. if you can’t find a source specific to your topic, try to find a general one (such as an encyclopedia that covers your topic or some aspect of it).

Our library (like most college libraries) uses the Library of Congress catalog system to organize the bookshelves (as opposed to the Dewey Decimal System). This system, which relies on the use of both letters and numbers, is one you need to become familiar with. Each call number begins with one or two letters, signifying a category of knowledge, which is followed by a whole number between 1 and 99,999. A decimal and one or more Cutter numbers sometimes follow. The Library of Congress system is pretty complex, but it’s not hard to use. As you get deeper into your research for this class, you’ll begin to recognize call numbers that consistently yield useful books.&nbsp.

Write 5 pages thesis on the topic rhetorical analysis of mlk jr’s speech i have a dream.

Write 5 pages thesis on the topic rhetorical analysis of mlk jr’s speech i have a dream. Martin Luther King employs a number of rhetorical strategies to make his speech effective and appealing to the audience. The use of rhetorical questions, metaphors, similes, epistrophe, anaphora, antithesis, tone, rhythmic use of language and the well-knit structure of the speech contributes to the effectiveness of the speech. The speech clearly demonstrates that Martin Luther King was quite aware of the nature of his audience. The speech is targeted at three types of audiences-the segregated blacks, the moderate whites who support the civil rights movement and the racist whites who condemn the civil rights movement. King’s intention is to stir the public opinion in favor of black liberation, freedom and equality. The speech is quite persuasive in nature and the speaker employs various rhetorical strategies all throughout the speech. From an Aristotelian point of view, the speech appeals to the ethos (credibility, ethics, character, honesty and confidence of the speaker), logos (use of reasoning to appeal to the reader) and pathos (emotional appeal) of the audience. However, a close analysis of the speech reveals that King predominantly tries to stir the pathos or emotional appeal of his audience through carefully planned rhetorical devices and this paper seeks to explore how the speaker tries to change the emotional status of the audience.

It is worthwhile to analyze the introductory part of the speech where King introduces the depth and severity of the segregation and inequality faced by the Black community in America. At the very outset of his speech king captures the attention of his audience by stating that the meeting will be ‘the greatest demonstration for freedom in the history’ of the nation. He then reminds the audience of the Emancipation Proclamation made by Abraham Lincoln a century ago and describes it as ‘great beacon light of hope to millions of Negro slaves.

The Politics of European Union Health Policies.

I will pay for the following article The Politics of European Union Health Policies. The work is to be 5 pages with three to five sources, with in-text citations and a reference page. Food supply would also be not affected as it relies majorly on agriculture productivity. I will also ensure that ecosystems would not be disrupted due to rising water temperatures as this causes ranging of habitat for various fish species.

Additionally, I would ensure that livestock may not be affected by heat stress and reduction in their feeds’ quality. The growth of various crops would not be affected due to changes in agricultural technologies and agricultural production practices. The impacts on crop yield may cause changes in the world export market since prices would vary according to the crop yields’ quality. Therefore, I would increase water bodies’ level due to global warming as this may cause a ruction in the size of land for agricultural production around water bodies. This would directly impact agricultural production in a reduction manner of output.

Weather conditions have a great effect on people’s lives as health is concerned. The effects of harsh weather conditions may occur directly, but the indirect occurrence may also be observed through the effects of disease-causing microorganisms. Extreme temperatures expose human health to great risk, such that excessive cold can lead to death due to long term exposure. Cite effects observed as a result of extreme heat include heat edema and heat stroke, which can also lead to death if the victim is not attended to at the right time. These effects are more dangerous to the elderly. Adverse weather conditions also affect people indirectly through affecting human resources like fisheries, agriculture and water. Humidity controls high temperatures, thereby regulating normal body functions to some comfort level. The adverse effect of humidity is that it can favor the reproduction and survival of viruses, parasites and other disease-causing microorganisms. Due to the common being headaches and onset of other weather-related diseases, sudden weather changes have resulted in body complications. Wind as a weather condition leads to the transfer of disease agents like insect vectors when they are blown from one region to another.&nbsp.

prepare and submit a paper on water crisis in the southwest region of the us.

Your assignment is to prepare and submit a paper on water crisis in the southwest region of the us. Many farmers in the Southwest region rely heavily on river Colorado for irrigation. This paper will explore the issue of the water shortage problem in the Southwest, what the future holds, and what can be done.

Water Scarcity and causes

Drought is the major cause of water shortage in the region. It has resulted in reduced low snowpack in the mountainous areas, temperatures have risen over 110 degrees increasing the rate of evaporation (Weaver par. 1). In addition, the Colorado water crisis has been enhanced by an increase in demand. Because of warmer temperatures in the region, millions of people have been moving into the region to enjoy it. In addition, they have built swimming pools and planted grass parks that require a lot of water.

Forests acts as water catchment areas, however, in the recent forest in the southwestern part of the United States have been burnt by wildfires (Fraser 3). In fact, the total area consumed by fire since the 1970s to the present is more than 10,000 acres. In addition, the costs incurred on fighting and suppressing wildfire is more than $3 billion a year. With this, it is evident that wildfires have been contributing factors to climate change in the region.

Water shortage problem

The region relies on two reservoirs that receive water from river Colorado: Lake Mead, which serves big cities such as Las Vegas and Los Angeles, and Lake Powell, which serves the upper Colorado basin. The biggest challenge is that now more than ever, the amount of water supplied by river Colorado to the reservoirs has reduced drastically. Furthermore, the volume of Lake Mead is expected to drop significantly due to the reduced inflow of water ( Weaver 3 ). With this, more than one million homesteads are likely to be affected negatively.

To bring all into perspective, Mead is the largest reservoir, not Justin the Midwest, but also across the country, and for the last fourteen years, it has lost nearly 20 cubic kilometers of water. The worrying thing is that the reservoir only holds close to 35 cubic kilometers of water.

Other findings indicate that from 2004 to 2013, about 65 cubic kilometers of water had been exhausted from groundwater supplies (Hudson 4-5). This, therefore, means that the underground water supplies of river Colorado have been reduced by more than half.

writing homework on A Diary from John Proctor to his Wife Elizabeth before He Died.

Need help with my writing homework on A Diary from John Proctor to his Wife Elizabeth before He Died. Write a 1250 word paper answering; &nbsp.Though he was the first male to be accused of witchcraft, Proctor was prosecuted and executed innocently. Proctor was vocal and always opposed the witch prosecution, which saw innocent people accused unjustly [1]in most cases. People took advantage of the prosecutions to settle scores through wrongfully accusing others of engaging in witchcraft. Proctor is also an example of a loving husband who loved his wife in all conditions. When his wife Elizabeth was wrongfully accused and imprisoned for witchcraft, Proctor did everything in his power to defend his wife against the accusation. When faced with death, Proctor pleaded for his life because he felt he was not yet fit to die at sixty but still ended up being prosecuted.

&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp. The hour is soon coming, sooner than I expected, when I face the almighty God, the overall judge of humanity. I am just human, but I believe I have earned a point in the final ruling through my honesty. I will have the courage to face my creator. Though I am not ready to go, I have to accept my fate and face death boldly. Even in death, I am grateful that I have left a mark in this world that will not be easy to get rid of. My honesty will be remembered for ages to come. The name John Proctor will be on many lips for ages. Even in my death, they will surely confess that I was not a witch, but a man who stood for the truth. My sincere belief that my children will forever be proud of me for my honesty and self-sacrifice. The truth will prevail, even in my absence. At my last hour, I still maintain that there is no witchcraft in the town and will stand by that to my grave.

&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp. My dear Elizabeth, how do I summarize the 18 years we have been together in marriage with few words. I truly appreciate your unwavering love and commitment to me at all times. Though I betrayed you, you were kind enough to forgive me. The love you showed our children, and I could not be measured. You are a truly humble but great woman. I am proud of being associated with you. Abigail was nothing more than just a passing wind. She tried all she could to come between us and even led me to betray you once, but that was in the past. Your forgiveness was the best I could get. Elizabeth, the love of my life, no matter how much Abigail wants me, am always yours. Abigail was that terrible nightmare that I would rather have her remain just a nightmare that I can wake up from.

&nbsp.Abigail’s claim of being bewitched marked the beginning of problems in Salem. Soon a gang of women was trading accusations of witchcraft. The plan was to destroy Elizabeth so that Abigail can have me for herself.&nbsp.

Write 5 pages thesis on the topic personal responsibility in combating pollution.

Write 5 pages thesis on the topic personal responsibility in combating pollution. The aim is to force these companies to behave responsibly in terms of the release of chemicals in the atmosphere. Failure on the part of corporations to follow environmental laws attracts penalties and increased taxes. This is because pollution affects the environment negatively, and it brings major human health issues with the rise in the cost of medicine to individuals. Bad air, for instance, has caused an increase in conditions such as allergies and asthma (Ferrera 25). In the Kyoto protocol, for instance, most of the industrialised and developing nations of the world committing to the reduction of carbon dioxide emissions by an average of 5% to the year 2012 basing their 1990 emission levels. Unfortunately, some major industrial powers of the world such as the US declined to ratify the protocol thus dealing a blow to the efforts. Furthermore, by the end of 2012 most nations were way below targeted in reducing their emissions. It is, therefore, imperative that people pressurize their governments to act urgently to combat pollution.

Bahrain is one of those economies that rely heavily on oil and industry and as such is at a high risk of environmental pollution due to issues like oil spills and chemical contamination (Number 14). Al Jazeera Beach is one area with high levels of pollution in Bahrain. The beach, for instance, does not have any garbage collection bins, and the conclusion of this is that people can just drop their wastes anywhere. To make the situation even worse, there are no laws in Bahrain regarding waste disposal and public hygiene in places of national importance such as beaches. Authorities, therefore, rely on the local societies, public schools and community efforts at garbage collection to ensure public sanitation. In fact, it should be noted that the state is passionate about the fight against pollution and this explains the existence of many projects geared to tackle the pollution problem, as well as its&nbsp.dangers (Ali 12).
