10 Narrative Essay Topics on Nuclear Corrosion

10 Narrative Essay Topics on Nuclear Corrosion As the world advanced into the nuclear age, were nuclear energy became an alternative energy source to coal and petroleum products, the need to understand nuclear materials and their corrosion has become an important aspect of science. Understanding corrosion mechanisms, the systems and materials they affect became even more important for human and environmental safety after the Russian debacle in 1954 and the more recent Japanese Nuclear disaster in 2009. The constant use of nuclear materials has made it important for nuclear corrosion to be taught and discussed in educational institutions. Therefore, if you are tasked with writing a narrative essay on nuclear corrosion, then this article will provide you with enough resources in terms of important facts which you can use to discuss or narrate your perspective on nuclear corrosion. Also, to adequately discuss nuclear corrosion, the mining of nuclear materials and the system put in place to manage nuclear activities must also be covered. So here are 10 facts on nuclear corrosion: Corrosion in nuclear plants is a pertinent problem. The materials used in securing nuclear plants in other to ensure radiation is curtailed are always susceptible to corrosion and statistics show that the nuclear industry have lost approximately $10 billion due to nuclear corrosion. Therefore in other to keep nuclear plants safe and functioning in a stable environment, material corrosion must be dealt with. Corrosive resistant materials are used to secure nuclear plants. To manage nuclear corrosion, metallic alloys which are highly resistant to corrosion are usually employed in the different types of nuclear power plants. In pressurized water reactor power plants (PWR) and boiling water reactors, the main types of materials used to avoid corrosion are Inconels, Stainless Steel, Zirconium alloys and Copper alloys are great for building a secure environment. Nuclear metallic materials experience corrosion in time. Although some metallic materials are highly resistant to corrosion, this does not mean they are totally immune to it. These metallic materials tend to experience the following types of corrosion; stress control cracking, irradiation-assisted stress corrosion cracking, environmentally assisted cracking and microbiologically assisted cracking. Therefore, the state of metallic materials in Nuclear plants have to be accessed on a regular basis to note the possibility of corrosion occurring. The nuclear industry has developed techniques to combat corrosion. Due to a history filled with radiation management issues, stakeholders in the nuclear industries have come up with various techniques to eliminate the possibility of corrosion. The use of Titanium alloys in nuclear power plants has been successful in combating corrosion due to its very high resistance to the different types of corrosion. Also, facing the ageing issue facing nuclear power plants head-on with the quick replacement of ageing systems has helped stabilized the nuclear industry. US nuclear plants are the most secure from corrosion. Statistics show that in the United States, nuclear power is currently responsible for approximately 20 percent of the US electricity production capacity. There are also over approximately 100 power plants operating in the US. Regardless of the numbers, strict measure put in place regarding the construction on power plants and management of nuclear waste makes the US nuclear program the most stable and secure worldwide. Managing nuclear waste is a more important issue than nuclear corrosion. Advances in science have led to the discovery of corrosion resistant materials as well as a better understanding of the materials used in nuclear power plants. This knowledge has led to the increased stability of power plants worldwide. Today, while corrosion still remains an issue, solving the problem of disposing nuclear waste and managing disposal sites in order to keep the environment safe pose more problems than dealing with nuclear corrosion. Corrosion of nuclear materials has resulted in nuclear accidents. Corrosion of nuclear materials as well as human errors has resulted in some of the worst nuclear disasters worldwide. The notorious 1986 Chernobyl incident was in part due to the use of materials susceptible to corrosion in the nuclear plant’s reactor core. Other nuclear incidents which have led to environmental pollution have been due to corrosion of nuclear materials. Despite the problems associated with nuclear corrosion, nuclear power is still safe and secure. Statistics from case energy- an environmentalist organization- serves as proof that nuclear energy has the lowest impact on the environment and it is a safe and secure energy source. The statistics go on to show that nuclear energy provides approximately 64% of the carbon-free power supply across the US. Also the high regulative process of running a nuclear facility such as a 24hr use of inspectors makes nuclear power plants quite safe and secure from the ravages of nuclear corrosion. The building and management of nuclear power plants is economically beneficial. Nuclear power plants provide a level of economic growth most industries can only dream of. During the building phase, approximately 2,000 construction jobs are created through the construction phase. And after completion, the average nuclear energy facility employs 400 to 700 full time workers thereby providing jobs in its resident communities. Next-generation nuclear systems are being built to counter corrosion and human error. Over the last decade, nuclear material scientists and engineers have focused their energies in building next-generation systems which will be less reliant on fusion-type reactors. These next-gen systems will consist of high temperature reactors and a wide range of new materials developed to counter corrosion effectively and they will be the nuclear materials of tomorrow. Here we come to the end of today’s interesting facts on nuclear corrosion, its causes and effects on the environment as well as the economy. To further help students write excellent essays on nuclear corrosion, two complementary reading materials - 20 topics for a narrative essay on nuclear corrosion and how to write a narrative essay on corrosion- will be included in this series. These reading materials are written to serve as samples which will provide you with enough guidelines to write your own narrative essays on nuclear pollution. References: Kilian, R. Roth, A. (2002).

Definition and Examples of Duality of Patterning

Definition and Examples of Duality of Patterning Duality of patterning is a characteristic of human language whereby speech can be analyzed on two levels: As made up of meaningless elements;  i.e., a limited inventory of sounds or phonemesAs made up of meaningful elements; i.e., a virtually limitless inventory of words  or morphemes  (also called  double articulation) Definition [D]uality of patterning, says  David Ludden, is what gives language such expressive power. Spoken languages are composed of a limited set of meaningless speech sounds that are combined according to rules to form meaningful words (The Psychology of Language: An Integrated Approach, 2016). The significance of duality of patterning as one of the 13 (later 16) design features of language was noted by American linguist Charles F. Hockett in 1960. Examples and Observations Human language is organized at two levels or layers simultaneously. This property is called duality (or double articulation). In speech production, we have a physical level at which we can produce individual sounds, like n, b and i. As individual sounds, none of these discrete forms has any intrinsic meaning. In a particular combination such as bin, we have another level producing a meaning that is different from the meaning of the combination in nib. So, at one level, we have distinct sounds, and, at another level, we have distinct meanings. This duality of levels is, in fact, one of the most economical features of human language because, with a limited set of discrete sounds, we are capable of producing a very large number of sound combinations (e.g. words) which are distinct in meaning.(George Yule, The Study of Language, 3rd ed. Cambridge University Press, 2006) Duality of Language and Animal Communication The level of sounds and syllables is the province of phonology, while that of meaningful elements is the province of grammar and semantics. Has this kind of duality any analog in animal communication systems?... The short answer to [that] question seems to be no.(Andrew Carstairs-McCarthy, The Origins of Complex Language: An Inquiry Into the Evolutionary Beginnings of Sentences, Syllables, and Truth. Oxford University Press, 1999) It is hard to find clear and uncontroversial examples of duality of patterning outside our own species. But let us say that we can find them- and there is evidence, from the way some animals like birds and dolphins manipulate melodies, that this might be true. This would mean that duality of patterning is a necessary condition for a communication system to be a human language, but that by itself it may not be enough. There is no human language without duality of patterning.(Daniel L. Everett, Language: The Cultural Tool. Random House, 2012) Hockett on Duality of Patterning [Charles] Hockett developed the phrase duality of patterning to express the fact that discrete units of language at one level (such as the level of sounds) can be combined to create different kinds of units at a different level (such as words)... According to Hockett, duality of patterning was probably the last feature to emerge in human language, and it was critical in separating human language from other kinds of primate communication...The most difficult bit to figure out is how and when duality of patterning could have emerged. How did individuals manage to isolate various bits of calls so that they could be endlessly combined into arbitrary symbols? Hockett thought that if two calls each had two distinct parts, then perhaps something in the blending process might alert individuals to the existence of discrete units. If you can combine breakfast and lunch into brunch, then does that alert you to the possibility that br is a distinct unit of sound that is combinable with other dis tinct units of sound? Solving this puzzle remains one of the thorniest of the problems in determining how language became possible.(Harriet Ottenheimer, The Anthropology of Language: An Introduction to Linguistic Anthropology. Wadsworth, 2009) The Structures of Phonology and Syntax The question of whether the structures of phonology and syntax are separate and distinct is relevant to the notion of duality of patterning... The division between meaningful and meaningless elements is less sharp than it appears, and the fact that words are composed of phonemes is arguably just a special case of the pervasive hierarchical structure that is present in language...Of all Hocketts design features, duality of patterning is the most misrepresented and misunderstood; in particular, it is frequently conflated with or linked to productivity (Fitch 2010). Hockett seems to have regarded duality of patterning as the single most important breakthrough in the evolution of language (Hockett 1973: 414), yet he himself was unsure whether to ascribe duality of patterning to the dance of the honeybee (Hackett 1958: 574).(D.R. Ladd, An Integrated View of Phonetics, Phonology, and Prosody. Language, Music, and the Brain: A Mysterious Relationship, ed. by Michael A. Arbib. MIT Press, 201 3)

Module 5 - Case Managing Workplace Safety and Health Assignment

Module 5 - Case Managing Workplace Safety and Health - Assignment Example The law gives permission to CMS for variety of actions like it may charge fines to the nursing home, even assign a temporary manager. If the nursing home fails to correct its misgivings, CMS has right to terminate certification agreement and thereafter it ceases to be a provider as the nursing home. Providing care, safety to nursing home residents is an uphill task. The residents often require assistance in performing daily activities including bathe and walk. The injury prevention efforts should focus on resident lifting and handling methods. A working group is to be formed to study above safety hazards and action plan to be prepared in consultation with the experts. That action plan is to be implemented in accordance with the OSHA regulations. Full-fledged records are to be maintained for future corrective action and monitoring of the each major type of incidents. There are several elements to Safety and Health program, which will be formulated, developed, and monitored to see that they are strictly followed. Outcome from each of the accident prone area so obtained will be compared with the previous month’s incidents so that progress made on each count can be notified and next corrective action is initiated. It will be a continuous process and may last for several months until desired levels of safeguards, quantitatively and qualitatively, achieved. Following are the areas, which will be studied intensively and form a part of the safety and health program. United States Department of Labor has devised guidelines to reduce the manual lifting of the residents. Ergonomic study is required to be done with respect to lifting and handling the residents for their many daily activities to increase safety of the staff and residents. Repetitive, forceful and prolonged actions of the hands with lifting, pushing, pulling of heavy objects and awkward postures could cause normal to serious injuries in the long

Object Database Management System Essay Example | Topics and Well Written Essays - 2000 words

Object Database Management System - Essay Example There are two most important factors that lead users to implement object database technology. Firstly, relational databases turn out to be cumbersome to use with composite data. Secondly, data is usually operated by application software written using object-oriented programming languages such as C++, Java, Delphi and C#, and the code required translating between this demonstration of the data and the tuples of a relational database can be dreary to write, and prolonged to execute. This variance between the models used to represent information in the application programs and the database is sometimes referred to as an impedance variance. Now a day Client-Server applications that depends on a database on the server as a data store while servicing requests from multiple clients are quite ordinary. The majority of these applications use a Relational Database Management System (RDBMS) because their data store while using an object oriented programming language for development. The "impedance mismatch" caused as a result of having to map objects to tables and vice versa has long been accepted as an essential performance penalty. Object-oriented databases are designed to work well with object-oriented programming languages such Java, C#, and C++. ODBMS used exactly the same model as object-oriented programming languages. Object database management systems added the notion of persistence to object programming languages. The early commercial products were integrated with various languages: GemStone (Smalltalk), Gbase (Lisp), and Vbase. (COP). COP was the C Object Processor, a proprietary language based on C that pre-dated C++. For much of the 1990s, C++ dominated the commercial object database management market. Vendors added Java in the late 1990s and more recently, C#. (Object database - Wikipedia, the free encyclopaedia) Theory We now introduce some basic concept of general system theory. This is essentially a way of understanding a system in terms of those components and characteristics that are common to all systems. We use the term system here in a very specific sense; although one that has much broader application than just computer systems. In everyday speech people may refer to the legal system, a tropical storm system, the system of parliamentary democracy, an eco-system, a system for winning at roulette, a computer system in someone's office, a system for shelving books in a library, a system-build house and many more. Some of these certainly meet our definition of a system and others do not. Probably the only thing that they all have in common is that they have some kind of organization. But in general systems theory, a system is rather more than just anything that shows a degree of organization. Characteristics of a system A system exists in an environment. A system is separated from its environment by some kind of boundary. Systems have inputs and outputs. They receive inputs from their environment and send outputs into their environment. Systems have interfaces. An interface allows communication between two systems. A system may have sub-system. A sub-system is also a system, and may have further sub- systems of its own. Systems that endure have a control mechanism. System control relies on feedback (and sometimes feed-forward). These comprise information about the system's operations or its

Clinical Journal One Essay Example for Free

Clinical Journal One Essay The nursing process is an assessment, diagnosis, plan, implementation and evaluation of our patients. As a practical nursing student this is something we are learning and improving on daily. Assessment is the most important part of the nursing process. This process is becoming clearer every day spent in the clinical setting. The assessment part of the process is done with every interaction of our patients we are taught in school. I thought how could that be assessing something takes a considerable amount of time so assessing every patient, every interaction sounded absurd to me. Currently my clinical setting is a post surgical unit. The nurses on this unit are registered nurses with varying amounts of experience. As I observe the nurses, I have noticed they actually do assess everyone, every time. I was amazed how easy this skill seemed to them of course experience helps in that area. I had the opportunity to participate an assessment of a month old child. During this experience I was able to understand the doorway assessment I learned about in growth and development and it made more sense to me . I was able to take a set of vitals on this baby, weighed a diaper for the IO and was shown how to assess the IV site on an infant. I realize how very important a quiet baby is during the assessment because of this experience. Assessing an infant is different than adults. Infants are a bit harder to assess if they are not calm. Upset babies respirations will increase. I learned how to feel for the fontanel and dehydration signs in infants. There is so many parts to assessment and each and every part is an important step in keeping your patient on the path to recovery. Post-op assessment require that you check patients pedal pulse, this is something I would not have thought to be important but I have since discovered that pedal pulse is a warning sign for post-op patients. The  smallest part of assessing a patient is just as important as the biggest parts. So a pedal pulse takes a minute or two to be sure it’s present and equal in both feet but the importance of doing this step in your assessment lasts forever because you deterred your patient a problem by doing a full head to toe assessment. Though, hands on assessments are most important, I have learned I do not always have to touch my patient to assess their condition. I can learn a lot from them just by listening to them and taking a good look at them. Patients also need more than a physical assessment. Physical head to toe is done at the beginning of your shift but you do and you can assess everyone with every interaction. There are many parts to assessment. The physical, of course, but as a nurse you must figure out the needs of each patient beyond the physical. They need emotional support as well. We must look at the whole picture when assessing. Do they need physical therapy? Home care? Support services? Are they going to need additional information on ways to be safe at home. Maybe the patients going to a rehabilitation facility after discharge so they may need to be assessed for which facility they would   gain the most from. We must assess if they require special equipment to improve on their independence. Assessing your patients doesn’t stop at taking a pulse or blood pressure.  So, assessment is very important and is easily done at every interaction once you see it done in the clinical setting. I still have so much to learn when doing a patient assessment but now I understand my role of assessing the patient as a licensed practical nurse and I understand the importance of every interaction assessment.

Theodore Roethke and The Waking :: Waking Essays

Theodore Roethke and The Waking In describing the way he receives life's lessons and learned experiences, Theodore Roethke uses repetition of two different sentences and a simple rhyme scheme to help the reader understand his outlook on how to endure life. The two sentences repeated throughout the poem are "I wake to sleep, and take my waking slow" and "I learn by going where I have to go" [with slight variation in the latter]. "I wake to sleep, and take my waking slow" shows up in stanzas 1, 2, 4, and 6 and figuratively means that Roethke awakens in the morning and learns from the day's experiences. Unlike most people, Roethke does not rush through the day as if he expected another. He lives through the day in a calm and slow manner so that he learns about life without missing anything along the way. At night, he falls asleep content with the day's experiences and awakens the next morning in the same slow manner. When Roethke states "I learn by going where I have to go" in stanzas 1, 3, 5, and 6, he declares that he goes anywhere and everywhere to experience all that he can. He observes rare things throughout his journeys and makes mistakes along the way, but wherever he goes, he locks the experiences in his memory and repeats the cycle. The repetition of the sentences in the poem set a tone of determination and perseverance to enjoy all of life's experiences that come Roethke's way. The emotion portrayed by the sentences is an uplifting feeling because Roethke observes and enjoys even the most trivial aspects of life such as when "the lowly worm climbs up a winding stair." The rhyme scheme initiated by the author follows the rhyme scheme ABA in the first two stanzas, CDA in the third through fifth stanzas, and ABAA in the final stanza. This particular rhyme scheme creates a comfortable flow of overt rhyming. In the first two stanzas, the rhyming is the same (ABA) as Roethke talks about how to experience life by feeling. The rhyme scheme changes in the third through fifth stanzas as the focu s in the topic changes to how Roethke epitomizes his "experience by feeling" idea by sharing the specific examples of the worm and the ground. The last stanza returns to an ABAA rhyme scheme much like that of the first two stanzas.

Admission Seeking Interviews Essay

There are several reasons why a person would consider and actually go through with committing fraud. It could be due to a perceived pressure, for example financial problems, abuses like drugs or alcohol, pressure from superiors, or simply because the individual is a disgruntled employee who thinks the company â€Å"owes them†. Or the reason could be they want to increase their lifestyle like â€Å"keeping up with the Joneses†. Other pressures could come from superiors who coerce employees to go along with the fraud or lose their jobs. Fraudsters rationalize their misdeeds with thoughts like; they will replace the stolen asset in the near future before anyone notices, or maybe the boss is doing it so why can’t I? Higher level employees like the CEO may rationalize that stock prices will be higher if they manipulate the financial statements, after all who they are hurting? It all comes out in the wash, right? Creative accounting is all it takes and adjustments could be made in the future to remedy this year’s fraud. Individuals who do a fraudulent act typically have the opportunity to commit the fraud. It could be because of shoddy internal controls; even with good internal controls a determined person could find a way to override them. A CEO or manager may think they are high enough on the totem pole that no one would question their antics. Once a fraud has been discovered or reported the fraud examiner must do his/her homework. They must secure data and documents to determine if a fraud has actually happened. Once all the evidence has been gathered about the crime and the subjects background has been determined the fraud examiner sets up an appointment which could be a planned or spontaneous event. He/she would interview the interviewee using a variety of techniques and executing objectivity, fairness and professionalism at all times. The subject who thinks the interviewer is out to help them and does ot judge their misdeeds would be more forthcoming with information so it is important that the interviewer thanks the person periodically offers breaks and concessions lie coffee or a drink. Once it has been determined that the subject was involved through investigation and preliminary interviews the examiner would sympathize with the subject stating such things as â€Å"anyone would do that in your position†. It is important that they establish a rationalization and motive for the fraud. The fraud examiner could produce other witness’ statements to try to get the subject to reveal their motive. Once the motive or rationalization is uncovered it would be important to discover how the act took place. What opportunities did the subject have to commit the crime? Examples could be poor internal controls, management that was lax, or the fraudster was capable of outsmarting his superiors. There are many recommended methods to have a successful interview. Each case is unique and has to be handled in a different way, but the outcome is pretty much the same. The purpose to an admission seeking interview is to determine how it was done, opportunity, why it was done, rationalization, and finally what made the person do it, perceived pressure. In closing, people are complex and unique in their make-up; there is no mold or template that determines who will commit a fraud or why they may do it. Not all people that have pressures for example sole providers of a struggling family, or can rationalize a reason, or have the opportunity will commit a fraudulent act. Basically we all have to live our lives under a certain code of conduct. People who deviate from the honest worker lack morals in my opinion. It is up to the examiner to uncover the truth. The fraud triangle is a helpful tool that gives a standard of the typical fraudster. Classifying potential pressures, opportunities, or probable rationalizations and by using the techniques of a successful interviewer one should net the desired result in determining if the subject is indeed guilty or just being set up by the whistleblower for whatever reason.
