He should have adopted active listening. The physician was additionally patronizing his patient by speaking slowly to her, which she was to a great degree irritated by. Older adults typically have a negative stereotype, which he encouraged by advising her that she was delicate due to seniority. When in reality she is extremely active and healthy. He should have established a foundation of trust, and demonstrated sympathy and welcomed feedback. There was a tremendous disconnect in communication with all encounters that day at the emergency room. This was not only a negative experience but also a complete waste of time.

Wayang Kulit free essay sample

Origin: The term Wayang is the Japanese word for shadow, or Bayang in Indonesian and Malay. In modern Javanese and Indonesian vocabulary, Wayang is often associated with the puppet itself or the whole puppet theatre performance. History: Wayang is a general term meaning traditional theatre in Indonesia. This art was imported from India or China, both of which have a long tradition of shadow puppetry and theatre in general. However, there very well may have been ingenious storytelling traditions that had a big impact on the development of the traditional puppet theatre. Wayang Kulit is a unique form of theatre employing light and shadow. The puppets are crafted from buffalo hide and mounted on bamboo sticks. When held up behind a piece of white cloth, with an electric bulb or an oil lamp as the light source, shadows are cast on the screen. The plays are based on romantic tales, especially the classic Indian epics, the Mahabharata and the Ramayana. Some of the plays are also based on local happening or other local secular stories. It is up to the conductor or dalang or puppeteer to decide his direction. The dalang is the narrator for the entire performance. He sits behind the screen and narrates the story. With a traditional orchestra in the background to provide a melody and its conventional rhythm, the dalang changes his voice to create suspense thus heightening the drama. Wayang today is both the most ancient and most popular form of puppet theatre in the world. Hundreds of people will stay up all night long to watch the superstar performers, dalang. Spiritual Significance The wayang kulit art form may be over 800 years old. The fact that the story is told using shadows is very important since moving shadows can be seen but never touched. One belief was that the souls of the ancestors were brought to life as shadows that provided advice and support. So wayang kulit performances have a spiritual and magical significance for Javanese and Balinese people. Everyone present at a shadow puppet performance is believed to be protected from evil influences while the play lasts. People will sponsor a performance to give thanks for someone recovering from illness. The screen represents the white universe in which people live their lives. The bright side of the screen represents the material world in which we live. The darker side represents the mysterious after-life. The oil lamp was often in the shape of the Garuda bird, and represents the rays of the sun which give life to every living thing. There may be several puppets for the one character. Depending on what the different colours to indicate its mood. Gold represents harmony, love of beauty and the finer things in life; dignity and calmness. Black represents more reflective, inward-looking characteristics, calmness and control; but sometimes anger and strength. Red represents physical strength, but a tempestuousness or fury. White represents flexible characters that are knowledgeable and full of life, as well as nnocence, youth or purity. The size and nature of the puppets depends on their character and station in life -as an ordinary person, god or demon. The puppeteer or dalang will have the good puppet characters standing in th or banana trunk to his right and the bad puppet characters to his left. This connects with the idea underlying wayang kulit that in every person there is a struggle between good and evil. The banana trunk represents the earth. Smaller puppets are closer to the dalang, and they are lined up from shortest to tallest. The puppets on both sides face in to the middle of the screen. The stories: Like most stories, including modern films, wayang stories often explore the battle between good and evil, and the problems that people face. Other stories were brought to Indonesia by traders from India. These include the great epic stories such as the Ramayana and Mahabharata. The performance: The play can be performed outside or inside, with the puppets being moved against a central white cloth screen that is lit up by an oil lamp or, in recent times, by an electric light. The audience can sit anywhere around the screen, but where they sit usually depends on who they are and on their social status. Explain that in our theatres too, eople can sometimes pay more for better seats. Although we often have theatres where the audience can only sit in front of the stage, some performances are done in theatre in the round or outside in venues such as parks and gardens, where the audience is free to sit where they like. A wayang performance usually takes place at night, often starting after 9:00pm and continuing until dawn as much as nine hours! This is a social occasion for the audience, and a chance to relax with friends and family. Since they often know the traditional story well, they may sleep, eat or talk during the less exciting parts. A ypical performance may be held as a celebration or major community event. Families come to the performance prepared to spend a long time enjoying each others company as well as enjoying the story. Wayang plays are performed around the world, including performances that often The gunungan: It represents the place where the gods, goddesses and demons live. It is a holy mountain where the tree of heaven grows. Mountains have been venerated in many parts of Asia since ancient times. For example, Gunung Agung is a sacred mountain to Balinese people. It is also a volcano and a powerful source of both good and potential disaster.

How to Prepare for the PSAT 5-Step Guide to PSAT Prep

How to Prepare for the PSAT 5-Step Guide to PSAT Prep SAT / ACT Prep Online Guides and Tips Many juniors and even sophomores take the PSAT every fall to prepare for the SAT. But the PSAT isn’t a college admission test, so do you actually need to prep for it?The reality is,PSAT prep can strongly benefit you, especially if you're hoping to naba National Merit scholarshipor get a high score on the SAT. In this article, we explain why PSAT prep is important and go over how to prepare for the PSAT using five simple steps. In addition, we discuss what kinds of resources are ultimately unnecessary for quality PSAT preparation as well as how PSAT prep differs from SAT prep. Why You Should Prep for the PSAT Most juniors take the PSAT, but in truth PSAT scores aren't nearly as important as SAT (or ACT) scores.Why? You see, because the PSAT isn't used for college admission, schools won't even so much as glance at your PSAT score. But if that’s the case, then, why bother prepping for the PSAT at all? As it turns out, there are a few reasons PSAT test prep may be worth the effort. For one, the PSAT is essentially a gateway to doing well on the SAT. Because theprimary aim of the PSAT is to prepare you for the SAT (hence its name, "Preliminary SAT"),the two testsshare several similarities. As a result,preppingfor the PSAT can give you an early sense of what SAT content areas you'll need to strengthen and what strategies and approaches work well for you. Even if you're planning ontaking the ACT instead of the SAT, the PSAT can still help you get used to the kinds of questions and content you'll need to know since there are so many similarities between the redesigned SAT and ACT. What's more, your PSAT score can predict your SAT score. Though the PSAT and SAT scoring scales differ (the maximum score is 1520 on the PSAT and 1600 on the SAT), each PSAT score directly corresponds to the same score on the SAT. So a 1300 on the PSAT indicates the same level of ability as a 1300 on the SAT does. The PSAT essentially shows you how well you’d perform on the SAT if you were to take it at that exact moment in time.Without any PSAT prep, however, you’re glimpsing what your SAT score would be without any SAT prep as well. Such a score isn’t particularly helpful, as you’ll most likely want tostudy for the SAT, so to get a more accurate SAT prediction, you'll definitely want to engage in some PSAT prep. Lastly, PSAT test prep is essential if you’re hoping to qualify for National Merit. All juniors who take the PSAT are automatically entered into the National Merit Scholarship Program, which awards annual $2,500 scholarships to top scorers. To qualify as a Semifinalist, you must reach or exceed your state’s PSAT cutoff score. Sothose aiming towin scholarship moneyshould study for the PSAT as diligently as they would for the SAT or ACT. Nonetheless, not everyone needs to prep for the PSAT or even take it.If you're not trying to hit National Merit, don't bother committing to lengthy prep sessions or long-term study plans. Likewise, if you're set on taking the ACT instead of the SAT, the PSAT won't be as helpful or as relevant to your studies, so feel free to forgo PSAT prep (and even the PSAT itself, if not required by your school). How to Prepare for the PSAT: 5-Step Plan Now that we’ve gone over why you should study, let’s look closely at how to prepare for the PSAT. Below are the five major steps you'll need to take in order to get the most out of your PSAT test prep. Step 1: Learn the PSAT Format The easiest and most fundamental way to prepare for the PSAT is to learn the format of the test. This is a great place to start, even for those who aren’t intending to aim for National Merit. As you may remember, the PSAT is very similar to the SAT, so if you’re at all familiar with the SAT format, know that the PSAT is strongly tied to it. The only major differences between the PSAT and SAT are that the PSAT: contains fewer questions lacksan essay component is slightly easier Here is an overview of the PSAT format: Reading Writing and Language Math No Calculator Math Calculator Order 1st 2nd 3rd 4th Time 60 mins 35 mins 25 mins 45 mins # of Questions 47 44 17 31 Question Types Multiple choice Multiple choice Multiple choice, grid-ins Multiple choice, grid-ins Topics/Skills Tested Vocabulary Ability to find evidence for answers in passages Data interpretation Ability to improve flow and style of passages (Writing only) English grammar and punctuation (Writing only) Algebra (linear equations, functions, inequalities, etc.) Nonlinear expressions Data analysis (rates, ratios, percentages, graphs, etc.) Geometry Trigonometry Complex numbers Scoring One Evidence-Based Reading and Writing (EBRW) score on a scale of 160-760 One Math score on a scale of 160-760 In addition, I suggest reading our basic guide to the PSAT for answers to any general questions you might have about the PSAT, such as what it tests, how it’s scored, how much it costs, and how to register for it. Next up, set a goal score! Ideally, one higher than 17. Step 2: Set a PSAT (or SAT) Goal Score A PSAT or SAT goal score can help you determinewhat PSAT score to aim for on test day. If you want to qualify for National Merit,your PSAT goal score should be equal to or higher thanyour state’s cutoff score.(Note that cutoff scores are usually reported as Selection Index scores, but you can find estimated PSAT score conversions in our article on the PSAT score range.) In general, you must score around1400-1480on the PSAT to qualify for National Merit. As previously mentioned, the exact score you'll need varies depending on the state. Regardless, you'll have to aim high! If you plan on eventually taking the SAT, you could also set a combination PSAT/SAT goal score. To do this, you must have a rough idea as to what colleges you want to apply to as a senior. Once you've got your list of schools ready (you can use our handy chart), find the 25th and 75th pecentile SAT scores of admitted students to each of your schools. After, look for the highest 75th percentile score on your chart.This score will be your goal score for both the PSAT and SAT,as it's the score most likely to get you into all of the schools to which you're applying. Ultimately, if you can hit on or around this goal score on the PSAT, you should have little trouble getting the same score on the SAT. And even if you don't hit it on the PSAT, you'll know exactly what to work on during your SAT prep so that you can raise your score by the time you sit for the SAT. Step 3: Take PSAT Practice Tests If you really want to do well on the PSAT, one of the best ways to prepare for it is to take at least one official PSAT practice test. You can download thesefree, full-length tests by going directly to the College Board website. Of all possible PSAT study materials, practice tests are arguably the best resources available. With practice tests, you’re getting authentic PSAT questionswrapped up in a complete test-taking experience. Unfortunately, since the PSAT only recently underwent changes in 2015, there aren’t a ton of practice tests to choose from. Here is what you can currently access: Official PSAT Practice Test #1 - Scoring Your Test - Answer Explanations Official PSAT Practice Test #2 - Scoring Your Test - Answer Explanations Other solid options for PSAT practice includeIvy Global’s PSAT practice test PDF- a high-quality, albeit unofficial, practice test- and official SAT practice tests (which we'll discuss more in Step 5). The Ivy Global practice test is a full-length test that's extremely similar to the official PSAT practice tests.The only downside is that its scoring guide uses the SAT scale (out of 1600) instead of the PSAT scale (out of 1520), making it a slightly less accurate representation of the PSAT. Practice tests are excellent tools for tracking your progress.What you'll want to do is take one practice test at the beginning of your studies to get yourbaseline score (i.e., the score you start with). Then, follow Step 2 above to set a PSAT/SAT goal score.Once you've completed some PSAT prep, take another practice test to see whether you're closer to hitting your goal score. As you take these PSAT practice tests, always simulate real testing conditions as closely as possible.This means taking the test in a quiet room without distractions and timing yourself on each section as you'll be timed on the actual PSAT. Doing all of this ensures you'll have a clearer and more accurate sense of where your strengths and weaknesses lie. Step 4 is all about mistakes. My mistake? Following Donkey Kong. Step 4: Analyze Your Mistakes When studying, tryto understand why the incorrect answer choices you’ve chosen are in fact wrong.This means you'll need to go through all practice tests and questions you’ve used for PSAT prep, mark the ones you answered incorrectly, and spend time figuring out where your logic or calculations went wrong. Look to see whether there are any patterns in your mistakes. For example, are you consistently getting tripped up on certain question types? Do you tend to guess randomly instead of strategically? Do you struggle with certain skills or content areas, such as algebra or reading comprehension? Being able to pinpoint your mistakes and understand what you can do to fix them allows you to avoid making these same mistakes on the PSAT and even the SAT or ACT. Step 5: Use SAT Questions Tests for Extra Practice Other than the PSAT practice tests above, there aren’t many resources for PSAT practice questions. That said, there are tons of free SAT resources, with questions nearly identical to (though possibly harder than) those on the PSAT. Therefore, I suggest incorporating SAT materials into your PSAT prep if you're dissatisfied with the breadth of questions in PSAT practice tests. Like the PSAT, the best resource for SAT practice questions is the College Board, which offers dozens of free questions for the three SAT sectionson its website. All in all, there are: 24 Reading questions 22 Writing and Language questions 18 Math No Calculator questions 30 Math Calculator questions For additional practice, take afull-length SAT practice test.These tests are nearly identical to the PSAT practice tests, differing only in length (i.e., number of questions) and difficulty. Each SAT practice test also comes with an Essay section, which you can skip since there are no essays on the PSAT. While SAT questions and practice tests can be helpful for PSAT prep, remember that these resources arethe best free resources for SAT prep as well. Therefore, you may want to reserve some of these questions for future SAT prep (unless, of course, you’ll be taking the ACT- in that case, go ahead and use all SAT resources for your PSAT preparation!). Ready to open up your wallet? Or nah? Should You Hire a PSAT Tutor? Sign Up for Classes? Because the PSAT isn’t as important as the SAT or ACT,you generally shouldn't need to hire a PSAT tutor or sign up for PSAT classes. Remember, thePSAT is essentially just a practice test- it has no effect on your GPA or your chances of admission to college. So throwing a bunch of cash at a PSAT tutor or prep course will likely only waste time and money in the end. The only cases in which PSAT prep courses and tutoring sessions are useful is when you want to qualify for National Merit or get a super high SAT score. In these cases, additional PSAT guidance can shed some much-needed light on critical concepts and skills you need to work on in order to get the score you want. For most students, though,light prep and a self-guided study plan using free, high-quality resources is typically all you need to prepare effectively for the PSAT. Even just knowing the PSAT format can give you a leg up on test day! So try not to feel obligated to spend money on resources you may not actually need in the end. If you do decide to invest in tutoring sessions or prep courses, just make sure the price doesn't bother you and that you can apply what you're learning to the SAT as well. Bonus: Aiming for a National Merit Scholarship? If you're not sure you can self-study your way to a qualifying PSAT score, you'll love our PSAT prep program, PrepScholar. We designed our program around the concepts in this article, because they actually work.

There’s no other prep system out there that does it this way, which is why we get better score results than any other program on the market. Check it out today with a 5-day free trial: PSAT vs. SAT: How Is Test Prep Different? There's no denying that the PSAT and SAT are undoubtedly similar- but they're certainly not identical, and thus neither is their test prep. Below, we go over the three key ways in which PSAT prep differs from SAT prep. Intensity PSAT prep is generally far lighter than SAT prep. This is primarily due to the fact that the PSAT is just a practice SAT and therefore a far less important test. Specifically, SAT (and ACT) scores are a significant college admission factor, whereas PSAT scores are not.(That said, being named a National Merit Scholar can certainly give a boost to your college application, especially in regard to financial aid.) Availability of Resources Since the SAT is a more popular and ubiquitous test, you'll find that there aremany more resources available for SAT prep than there are for PSAT prep. This means you’ll have a broader range of materials to choose from when studying for the SAT- from prep books and apps to questions and practice tests- than you will for the PSAT. Essay Section Unlike the SAT, which includes an optional Essay,the PSAT does not include an Essay section.So if you’re taking the SAT with the optional Essay, you’ll need to make sure you adequately hone your writing skills prior to the exam.In other words, without having to practice composition, the PSAT is a slightly easier test to prepare for. Once you finish the PSAT, do a happy dance- ideally, with a frilly umbrella. Key Takeaways: The Importance of PSAT Prep If your goal is to perform well on the PSAT- whether because you hope to qualify for National Merit or simply want a better chance of scoring highly on the SAT- you’ll need to engage in some PSAT test prep.But if you're not aiming for National Merit or don't plan to take the SAT, you don't need to prep for the PSAT (or even take the test at all, if your school allows students to opt out). The best way to get started on PSAT preparation is to learn the format of the test, including what questions it’ll ask and what concepts it'll test you on. Setting a PSAT or SAT goal score, too, can help guide your studies. Finally, it's a good idea to spend some time analyzing your mistakes and practicing with high-quality PSAT practice tests and SAT resources. Most students shouldn't need to hire tutors or enroll in PSAT prep courses to do well on the PSAT. Because the PSAT isn’t a college admission test, scoring highly on it isn’t nearly as important as scoring highly on the SAT or ACT; therefore, there’s no point in spending money on PSAT prep unless you really want to qualify for National Merit and believe the resource will help you eventually get a high score on the SAT, too. As for test prep, PSAT test prep is typically less intense than SAT test prep, as the PSAT isn't as important as the SAT. Moreover, there is no Essay section on the PSAT and only a small number of PSAT resources available, making PSAT prep overall simpler than SAT prep. What’s Next?

Heres How to Tell Your Boss You Have Too Much Work

Heres How to Tell Your Boss You Have Too Much Work You’re totally swamped, but you feel like you can’t tell your boss or she’ll think you’re a wimp- or you’ll be written off for promotion because you just can’t cut the mustard. But if you’re not just being lazy (you’re actually overwhelmed because there’s genuinely too much on your plate), then you might just need to find the right way to broach the subject. Continuing to thrash around with your head just below the surface of the water is not going to win you any medals. You might actually do damage to your career. Remember that being overcommitted and dealing with exhaustion can lead to sloppy mistakes or cut corners- or even failing to get something done on time. Far better to give your boss a heads up so you can continue turning in the top notch work you’d rather put your name to.Here are some guidelines to follow.1. Make it about quality.The way to frame this is that you don’t want to sacrifice quality i n order to keep up a ridiculous level of output. Don’t make any accusations, just present the situation frankly. Say that you’re concerned the high standards you hold yourself to might suffer given your responsibilities overload. Emphasize that you’re totally up for turning out four high-quality projects at a time, but that six is a bit too much.2. Be concrete.Don’t just say you have too much work. Give concrete examples. Explain how you’ve been assigned several projects on top of your regular workload. And how any one of them would be fine, but cumulatively, you’re having trouble keeping balls in the air. Give an estimate of how much time it would take for you to complete each and then the aggregate time. Then explain how it would be impossible to meet all of the deadlines. Tell your boss all the times you’ve stayed late or worked extra hours to finish, without complaint.3. Discuss deadlines and delegation.It might be an easy fix, li ke staggering deadlines, or outsourcing some projects or tasks to other team members to get the thing done (and well) in a timely fashion- especially if there are any general administrative aspects that don’t require your skillset that could be passed along to support staff to free you up to concentrate on the meat of the project. Set clear priorities showing you value the most important projects and understand the importance of getting them done to standard.4. Stay positive.Soften the blow by focusing on the positive. Frame the conversation by saying â€Å"yes† to what you can do, and do well, and not â€Å"no† to all you can’t, i.e., you can do project X, but extra added-on projects and tasks might require you to sacrifice that very important project, which you are not prepared to sacrifice. Keep it positive and use an upbeat, devoted-to-the-company tone, rather than one of despondence or frustration. And show, above all, your willingness to pitch in.5. Ask for help.Never underestimate the power of a third party to help ground you when you’re feeling overwhelmed. Get an outsider’s perspective on your workload. They’ll either tell you to suck it up and get it done, or they’ll validate your feeling that you’re really being asked to juggle far too much.

What does it mean to be Canadian Is it worth it for the Chinese to Essay

What does it mean to be Canadian Is it worth it for the Chinese to come here and build Canadian Pacific Railway - Essay Example Although the people come from a diversified background, they identify themselves as being Canadians and having attributes which makes them proud to be associated with Canada. To a great extent, a key role is played by the television, media, and literature in promoting feelings of nationalism and unity within Canadians despite their varied backgrounds. In particular, emotions have been creatively used to have an overwhelming impact on its audiences in order to stimulate feelings of patriotism and loyalty towards Canada (Burke, 104-107). Canadians take pride in belonging to a country which has a fascinating social, cultural, and historical background and they have a positive attitude towards the country (Cohen, n.pag.). Its inhabitants may be different in appearance however all Canadians share similar values and encourage the expression of personal beliefs and thoughts on their identity as a Canadian. Marusya Bociurkiw in Feeling Canadian: Television, Nationalism and Affect examined th e part played by television in the construction and dissemination of feelings of nationalism among its inhabitants. Canada has often been described as being similar to the USA however American and Canadian sentiments as to what it means to be a Canadian differs greatly. It is also important to account for the considerable diversity present in the Canadian society. Burke analyzes how Bociurkiw has considered sensory and emotional aspects of television content and how a sense of national belonging is created through the television programs (104-107). Television provides a great way of connecting the public with the society through affective perceptions. A documentary film by Robert Cohen named Being Canadian is in the making which addresses the crucial question of what it means to be a Canadian (Cohen, n.pag.). The documentary is based on several interviews with Canadians while on a journey across Canada. This journey provided Cohen with a deep insight regarding the perception of peop le about being a Canadian. The responses make up the documentary and explain how positive people are about being a Canadian and the pride they take in belonging to this land. However, after generations of immigrants in Canada, it seems that the cultural value and the sense of Canadian identity is reducing among its dwellers. The creators of the documentary explore the Canadian territories and the invaluable assets which Canada is proud of. Along the way, several Canadians have been interviewed to describe the qualities, attributes, and values involved in being a Canadian and what it means to them. Diakiw in his essay considers the role of school in forming a feeling of Canadian identity as children try to assimilate the cultural values under Canadian settings (2). Although many immigrants have developed a sense of affiliation with the culture and identify themselves as Canadians, many are facing identity crisis as a result of mixed values and the multi-cultural nature of the country . Schools act as important educational centers for the dissemination of political and cultural views and because of a diversified community there is not single perspective of political or cultural view being communicated. Since schools are central curators of national outlook, it is necessary that schools are regulated in what they want to promote (Diakiw, 5). The Canadian government has promoted a multi-cultural policy and has developed easy procedures encouraging immigrants to migrate to

Enterprise network architectures constraints Essay

Enterprise network architectures constraints - Essay Example The effective use, utilization, and reliance on enterprise network solutions do not require extra manual labor (Calcraft & Adams, 2007). That is been the case leaders in different organizations prefer using enterprise network solutions in order to save on costs and increased expenses incurred in hiring employees to solve such problems. Enterprise network solutions are considered being an important tool of modeling and reshaping business processes (Gammon, 2010). It is the understanding of organizational leaders that enterprise network technologies are playing huge roles in modern organizations. Such roles take account of mitigating risks through the implementation of designs, which are suitable to an organization, and improving the general performance of the organization to meet future goal. The most common network architectures take account of Collaboration Architecture, the Data Center and Virtualization Architecture and Borderless Networks Architecture (Wolfrum, & Christopher, 2007). These network architectures have been approved by CICSO, and so they are functional and operational in different organizations. The choice of any architecture largely depends with the leader of the organization and the purpose of using it in the organization. Taking a look at the Borderless Networks Architecture, it is evident that basic idea behind it is to develop networks that are capable to exist without any perceivable borders. Such network significantly helps to solve emerging problem easily and automatically. On the contrary, Data Center and Virtualization Architecture has the goal to augment business value all the way through, system excellence, technology innovation, and solution differentiation (Gammon, 2010). The collaborative architecture on the other hand is based on mixture of diverse technologies used in other architectures (Bergman & Steven, 2009). In that manner,

Health Promotion Study Guide Essay Example for Free

Health Promotion Study Guide Essay Illness is an event that manifests itself through observable/felt changes in the body. Illness is the state in which the physical, emotional, social, intellectual or spiritual functioning is diminished or impaired compared with previous experience. It is NOT synonymous with disease and may or may not be related to disease. Illness is highly subjective. Wellness is the state of being healthy in both body and mind as the result of deliberate effort. Wellness is the state of well-being. It is an approach to healthcare that emphasizes preventing illness and prolonging life as opposed to emphasizing treating diseases. Anspaugh et al propose 7 components of wellness: 1) Physical 2) Social 3) Emotional 4) Intellectual 5) Spiritual 6) Occupational and 7) Environmental. Well-being/Wellness is a subjective perception of vitality and feeling well which can be described objectively, experienced, and measured and can be plotted on a continuum. Dunn’s concept of high level wellness theorizes that wellness is the degree of illness/health modified by the environment. It says that it is an integrated method of functioning that is oriented towards maximizing the potential of which the person is capable. It requires that the individual maintain a continuum of balance and purposeful direction within the environment where he is functioning. The patient’s perception of health, wellness and illness must be considered by the nurse in order to provide individualized, quality care. Lifestyle factors that influence health: (PP Health Promotion and Disease Prevention) Internal and external factors influence health status. Internal factors include Age, Genetics, Physiologic, Lifestyle, Health habits (smoking, drugs, alcohol, eating habits, exercise and stress). External factors include: Environment (radiation, air pollution, H20 and sun exposure), Safety (seatbelts, riding on motorcycle), and Standard of living (less educated the poorer the health). How to take a patient’s temperature using different routes: (Lab Kozier PP. 532-537) There are a number of body sites for measuring body temperature. The most common are oral, rectal, axillary, tympanic and temporal artery. Normal adult temperature is 37 degree C and 98. 6 degree F. In older adults ( gt; 70), temp is usually 36 degrees C or 96. 8 degrees F. Newborns- 1 yr old are usually 98. 2 degree F and 36. 8 degree C. Oral: Most common route. Place thermometer underneath the tongue on either side of the frenulum. Do NOT take in someone with mouth lesions or if patient has had oral surgery. Be sure to ask if patient has had anything cold/hot to drink in last 30 minutes. Rectal: Most accurate route. Place Pt. in lateral or Sim’s position. Apply gloves and instruct patient to take a slow deep breath during insertion. Insert 1. 5 inches in adults. Do NOT take in Pt that has had rectal surgery, has lower GI problems, is immuno-suppressed, has a clotting disorder or Pt that has hemorrhoids. In some agencies taking rectal temps is contraindicated in patients who have had an MI. It is believed that this can stimulate the Vagus nerve which can cause myocardial damage. Tympanic: Temps measured in this site are usually 1. 1-1. 5 degrees higher than oral. These are non invasive and quick. To measure temp, pull pinna slightly upward and back( adults) and point the probe slightly anteriorly, toward eardrum. Insert the probe slowly using a circular motion until snug. Axillary: The least accurate route but safest route. Dry arm pit if moist. Place thermometer bulb in center of axilla. In order to obtain a more accurate reading it must be left in place for a long time. Temporal Artery: Safe, noninvasive and very fast. Equipment slightly more expensive, as it is a scanning infrared thermometer. The probe is placed in the middle of the forehead then drawn laterally to the hairline. If Pt has perspiration on forehead the probe is also touched behind earlobe. Levels of preventive health care: Three levels of preventative care are: Primary focuses on health promotion and protection against specific health problems or health risks. Primary prevention precedes disease or dysfunction and is applied to generally healthy individuals or groups. Examples include: Immunizations; risk assessments for specific disease i. e. iabetes; health education about injury and poisoning prevention. Secondary- focuses on early identification of health problems and prompt intervention to alleviate health problems. Goal is to identify people in early stages of disease process and to limit future disability. It is curative in nature. It emphasizes health maintenance for people with health problems (i. e. someone with diabetes who has it under control). This level includes prevention of complications and disabilities. Examples include: Encouraging regular medical/ dental checkups; Teaching self exam of breast; screening surveys hypertension). Tertiary- focuses on restoration and rehabilitation with the goal of returning the person to optimal level of functioning, within the constraints of the disability. This level of prevention occurs after an illness, when a defect is stabilized or fixed and determined to be irreversible. Examples include: caring for someone with a chronic disease; referring patient with colostomy to support group; teaching patient with diabetes to identify and prevent complications ( heart disease); referring patient with spinal cord injury to a rehab to receive training to maximize his remaining abilities. Understand who the older adult is and physiological/psychological changes: Successful psychological aging is reflected in the older person’s ability to adapt to physical, social, and emotional losses and to achieve contentment, serenity, and life considerations. The older adult continues to learn and problems solve and intelligence and personality remain as they have always been. A person’s social ability does not change during the course of their life: if you were a young extrovert/introvert you will be an old extrovert/introvert. Wisdom increases as we age. As a person becomes older they go through physiological and psychosocial changes. Some physical changes are visible and some are not. In general lean body mass decreases, fat tissue increases, and bone mass decreases. Intracellular fluid decreases which can cause dehydration. Skin becomes drier and less elastic and they become more susceptible to skin tears. Bony prominences may become visible. There is a loss of overall stature and osteoporosis can occur in people who have insufficient intake of calcium and in women who have been through menopause. There is a steady decrease in muscle fibers. Reaction time slows. There is loss of visual acuity and progressive loss of hearing and reduced elasticity and increased rigidity of arteries and an increase in blood pressure. Orthostatic hypotension is common. GI changes include increase in indigestion and constipation. There is increase in frequency and urgency of urination and incontinence in many older adults. Decreased immune response and lowered resistance to infection is normal. Many older people have decreased thyroid function and increased insulin resistance. Respiratory efficiency is reduced with age. Older adults may experience many health problems including physical injuries and chronic disabling disease, and dementia. Psychologically people have much to adapt to as they become older. Some of these things are 1) Retirement – this is often a difficult time of adjustment for people. Many have a sense of self worth from working and lose a sense of identity when they stop working. Income decreases sometimes by 35% during this time. 2) Economic Change- Decrease in finances related to retirement and lack of pension plans/savings. Health care costs skyrocket because of increase in illnesses. This decrease in monetary resources can cause older people to become less independent. This causes them to lose self esteem and become depressed. 3) Grand-parenting: At this time in life older people become grandparents and are able to provide support to younger family members in a number of ways. 4) Relocating- many people move closer to their children for general support and supervision. This is a very big stressor. Older adults can either live with their children; live in assisted living, live at home with adult day care, live in a long term care facility or in private group homes. ) Maintaining Independence and Self Esteem- This is a big one. Elders thrive on independence and it is important for them to be able to maintain their self esteem. The more they can do for themselves the better. 5) Facing Death and Grieving as people age the chance of their spouse dying increases. Friends and family members die and this is a period of adjustment and grieving. The older person has feeli ngs of loss, emptiness and loneliness during this time. According to Erickson the developmental task at this time is ego vs. despair. People who attain ego integrity view life with a sense of wholeness and derive satisfaction from past accomplishments. This is the time of life where many older people start focusing on their faith and spirituality. Most people start an internal life review and seriously start thinking about their own imminent death. Caregiver Role Strain†¦what is it? What nursing interventions would the nurse provide? (P. 137) Caregiver role strain is when they have physical, emotional, social, and financial burdens that can seriously jeopardize their own health and well-being. Nursing intervention would be to encourage caregivers to express their feelings and at the same time convey understanding about the difficulties associated with caregiving and acknowledge the caregivers competence. Through conversation with the caregiver assess areas where assistance may be desired or need. Identify possible source of help. Like volunteer (family, neighbor, friends, church, caregiver support groups) or agency sources (home health aide, meals on wheels, day care, transportation, and counseling and social services. Remind the caregiver of the importance of caring for themselves. Know about these nursing diagnoses: Coping Ineffective, Fear, Anxiety (PP. 1069-1070) NANDA diagnostic labels related to stress, adaptation, and coping: Anxiety: Vague, uneasy feeling of discomfort or dread accompanied by an automatic response (the source often nonspecific or unknown to the individual); a feeling of apprehension caused by the anticipation of danger. It is an alerting signal that warns of impending danger and enables the individual to take measures to deal with a threat. Fear: response to perceived threat is consciously recognized as a danger. Ineffective Coping: Inability to from a valid appraisal of the stressors, inadequate choices of practiced responses, and/or inability to use resources. Terms associated with assessment of pulse (CHP 29, PP. 538-540) Assessment of pulse: Terms Locations: Temporal, carotid, apical, brachial, radial, femoral, popliteal, posterior tibial, pedal (dorsalis pedis) Pulse: wave of blood created by contraction of the left ventricle of the heart. Cardiac output: volume of blood pumped into the arteries by the heart and equals Stroke Volume (SV) X Heart Rate (HR) per minute. Compliance: ability of the arteries to expand Peripheral pulse: pulse located away from the heart Apical Pulse: central pulse; apex of the heart (PMI) point of maximal impulse Palpation: feeling Auscultation: hearing DUS: Doppler ultrasound stethoscope Tachycardia: excessively fast heart rate ( over 100 BPM in an adult). Bradychardia: A heart rate less than 60 BPM in an adult. Pulse rhythm: pattern of the beats and the intervals between beats. Dysrhythmia/arrythmia: irregular rhythm. Pulse volume: pulse strength or amplitude, refers to the force of the blood with each beat. Elasticity of the arterial wall: reflects its expansibility or its deformities. Perfusion: blood flow to a particular area of the body Understand different tools for therapeutic communication: (P. 469-470 box 26-2) Broad opening statement General leads Reflecting/paraphrasing Sharing observations Acknowledging feelings Silence Giving information Clarifying Implied verbal communication Summarizing Focusing (from power point #18 in communication) further information can be found on pg. 469 and 470 box 26-2 Different domains of learning: cognitive, affective, psychomotor: (P. 89) Cognitive domain the â€Å"thinking† domain, includes six intellectual abilities and thinking processes beginning with knowing, comprehending, and applying to analysis, synthesis, and evaluation. Affective domain the â€Å"feeling† domain is divided into categories that specify the degree of a â€Å"person’s depth of emotional response to tasks†. Psychomotor domain the â€Å"skil l† domain, includes motor skills such as giving an injection. Know normal vital signs for the adult and older adult. Average range for adults: (P. 529) 96. 8-100. 4. Older adults (gt;75) are at risk for hypothermia ( temperatures

Essay on Social Commentary in Catch-22 -- Catch-22

Social Commentary in Catch-22      Ã‚  Ã‚   Life is filled with situations that are very difficult to find an escape. Even once in a while, life presents a situation that is beyond difficult, and completely impossible to escape from. These situations were expanded upon and brought to obvious light in Joseph Heller's novel, Catch-22. This novel was such a masterful work that the phrase, catch-22 came to be synonymous with the situations that Heller portrays in his novel. Set in the final months of World War II, Catch-22 tells the story of a bomber squadron on the mythical island of Pinosa, just off of Italy. The story is told through the eyes of Captain John Yossarian, one of the few sane men in the novel, who sees all of the impossible situations his squadron is placed in. "For Catch-22 is the unwritten loophole in every written law which empowers the authorities to revoke your rights whenever it suits their cruel whims; it is, in short, the principle of absolute evil in a malevolent, mechanical, and incompetent w orld. Because of Catch-22, justice is mocked, the innocent are victimized, and Yossarian's squadron is forced to fly more than double the number of missions prescribed by Air Force code" (Skreiner 1). The mops vivid examples of the paradoxes created by catch-22 come from the specific characters; Hungry Joe, Doc Daneeka, Orr, Milo Minderbinder, and Yossarian.    Probably the most peculiar paradox presented in Catch-22 is formed around a pilot named Hungry Joe. Following a common, logical train of thought, Hungry Joe wishes to finish his time in the war and return home, where his safety is guaranteed, and he is in no danger of being killed. The catch originates from a common junction of many of the catches characters ... ... that he is so quickly able to persuade us (1) that the most lunatic are the most logical, and (2) that it is our conventional standards which lack any logical consistency"(Brustein 228). Catch-22 is about coping with what life throws you, then understanding the hopelessness, and still never giving up. Catch-22 is a novel that instructs the reader to do as Heller did, leave convention behind. It is wrong, only the individual matters, because without the soul, man is garbage.    Works Cited    Brustein, Robert. "Joseph Heller". CLC. 3:228. Heller, Joseph. Catch-22.

A lack of confidence â€Å"freezes† any chance of getting started but it was very inspirational to see some one who has the courage to start his own business in a foreign country and some more the owner stated that he has some other businesses in Malaysia although he is originally from Egypt. In addition the business operates in a very strategic place in UUM where all the students can get access to it which is near to University Inn hotel and the Arab restaurant and the nature of the business is grocery products such as beverages, biscuits, household products and the likes. Further more the target markets of the business are the customers of the hotel, the restaurant and the students residing in nearby university Inn and Maybank residential hall and the whole university since the reliability of the shop is high in terms of time it is 24/7 open which attracted so many customers and fulfilled the needs of the students incase of emergency need or any necessity. The business is specializing in wholesale & retail. Nourrz mini mart business foundation is based on its honesty in a step by step footprint, hardship spirit & also taking a stable footstep towards the future. The environment of the business is really satisfying however we have conducted an oral interview about the quality of the product, customer service and etc. 72% answers from customers said that the quality of the products sold in Nourrz mini mart is good while 18% answers from customers responded the quality is less than its competitors. Most of the respondents believe that it’s much lower price than its competitors however we would like to talk about the nature of the business, suggested income and productivity.

Weakness The weakness of the minimart is contributed by the constraint of space limit, limited staff sometimes the business runs short supply of the products it need and also the location of the business would have been better if it is located in the centre of the university or more strategic place. Opportunities. 1. It can expand their business 2. Arab product such as drinks and Arab bred. 3.

Recommendation Knowing how to successfully expand a small business is a skill that many business owners do not possess but we are giving the minimart to some suggestions like doing research before making any major decisions the more informed, the better will be the decisions that the owner make. To offer new products or services then first consider what the impact would be given current market conditions as well as your available resources. If you are planning on changing your location, then you should consider finding strategic position. Further more try to stay one-step ahead of your growth. To save on time, money, and productivity, you should try to be prepared for any future changes your small business is likely to experience. If, for example, you are renovating your location, then build into your plans more space than what you currently need. In addition watch your cash flow. It is common among small businesses to struggle with tight cash flow. This is all the more true when a business starts to rapidly expand. As growth happens, it is easy to loose sight of your expenditures. Since a lot of money is being directed outside of the business for new equipment, new supplies, or higher payroll expenses, a cash shortfall is usually inevitable. The minimart would be in a better position if you try to improve on the marketing skills for example awareness of the business by other customers so that they can get a lot of customers, Such as posting information in residential places in the campus. The businesses also need two to three more staff members to support each other on their routine in shift times. The business may need space for the products to be kept in position for sale. The space is not enough to accommodate the service that is being rendered by the staff. .

International Trade & Finance Speech Essay

International trade is essentially when two or more countries exchange goods and services. Many countries export their goods and services to other countries and in turn, they can also import goods and services from other countries to into their own. Advancements with technology have made it a lot easier for international trade to take place. Communication between countries is a good example. Communicating has vastly improved and helped to simplify the trading process. Some technologically advanced countries, like Japan and China have bountiful natural resources and that has a heavy impact on us. The United States is one of the largest contributors to international trade. Our GDP (Gross Domestic Product), is greatly impacted due to being huge import consumers. The United States relies heavily on products from other countries and we import much more than we export. Not only does this impact our GDP by lowering it as we import more than export, is also has an impact on our domestic markets because we are buying more from other countries. In regard to Foreign Exchange Rates, it is very important to know how they are determined. Considering economic growth within a country is important, governments can make certain that fiscal and monetary policies are in place to ensure that growth continues. Due to the goods and services that are traded between different countries around the world, there are foreign exchange rate payments that are required to be paid. You will see the foreign exchange rate differ from country to country. What happens when there is a surplus of imports brought into the U.S.? Cite a specific example of a product with an import surplus and the impact that it has on the U.S. Businesses and Consumers involved. First, it is important to try and keep imports and exports balanced. However, when one exceeds the other, it is called a surplus. Having a surplus of imports can create a lower price for the consumer, and have a positive effect on the employment rate of the country where the product was obtained. Seafood is a good example of a product with surplus. There are several states, mainly coastal states that have fishing boats out at sea for many months catching lobster, fish, crabs, etc. The seafood that is collected is used for both domestic sales and international export. This allows for several options when selecting fish, etc at the grocery store. It also increases your selection when out dining at a restaurant. A downfall could be that a surplus of seafood, fish, etc could result in a declining need for domestic fisherman to work and this could cause layoffs and cutbacks. What are the effects of International Trade to GDP, Domestic markets and University Students? GDP stands for Gross Domestic Product and international trade. GDP is the market value of all final goods and services produced in an economy in a one year period. (Colander, 2010) International trade is the exchange of goods and services between two or more countries. International trade greatly affects the GDP due to the fact that is we are able to have goods produced outside of the United States and the imported for sale at a cheaper cost than if we were to produce here, the consumer demands will increase and therefore help the GDP. Domestic markets are also affected by international trade as they have the ability to have products manufactured outside the United States at cheaper rates. This takes away from domestic manufactured product sales and could increase unemployment. On the reverse, it could affect domestic markets positively, as domestic retailers could mark up the products to consumers and keep the additional profit. International trade affects University students in a much different way. Suppose there was an increased demand for innovative ideas and qualified individuals to help keep our domestic markets alive? A University student could be a huge asset there. Also, the higher the GDP, more jobs will be available. If the GDP crashes, graduates should probably look for a job in another country. How do Government choices in regards to tariffs and quotas affect international relations and trade? Both International relations and trade are greatly affected by government decisions that are made about tariffs and quotas. Tariffs are the most familiar and most commonly used type of trade restriction. Tariffs are most often recognized as taxes here in the United States. Quotas are quantity limits that are placed on imports. These limits are decided by the government. The choices made by the government as it relates to additional fees for imports and limitations placed on the amount of imports directly affects international relations and trade. The positive side to this is that the government has the ability to control trade between themselves and other countries. This allows the United States to be picky. The ability to raise or lower tariff amounts gives us the power to possibly do business with underprivileged countries simply by lowering the tariffs as an incentive. They can also raise the tariff as a means to end relations with a country. What are foreign exchange rates? How are they determined? In regard to Foreign Exchange Rates, it is very important to know how they are determined. Considering economic growth within a country is important, governments can make certain that fiscal and monetary policies are in place to ensure that growth continues. Due to the goods and services that are traded between different countries around the world, there are foreign exchange rate payments that are required to be paid. You will see the foreign exchange rate differ from country to country. Why doesn’t the U.S. simply restrict all goods coming in from China? Why can’t the U.S. just minimize the amounts of imports coming in from all other countries? To put it simply, it is not possible for the U.S. to restrict all goods from China. This is mainly because there is an enormous trade deficit between us and China. China currently holds a very large portion of our nation’s debt and it would be a bad business decision to try and end relations when we still have a large debt owed to them. Not only do we have a large debt owed to China, the U.S. consumer has a very large demand for products that are made in China. China is one of the largest manufacturers of electronics and other luxury items, like the Iphone, Ipad, Ipod that we have come to rely upon. If we were to restrict all goods, we would not only destroy our economy, but also China’s economy. References: Colander, D.C. (2010). Macroeconomics. (8th ed).

Charles was a factory worker and her mother was a seamstress and a mother to help provide for the family. Young couples had a hard time making ends meet, and in hope of saving some of their money, they sent their children back to the Caribbean.

1886 Earthquake of Charleston Research Paper Example | Topics and Well Written Essays - 1000 words

1886 Earthquake of Charleston - Research Paper Example Even though the quake lasted less than one minute, its implications on Charleston were significantly damaging to property and life.1 It is estimated that the earthquake resulted in the destruction of more than 2,000 structures and buildings. The value of the damages which the earthquake caused is approximated to be over $145 million. The loss of human life is estimated to be about 108 people. Some of the negative implications of the 1886 Charleston earthquake are observed even up to the present days.2 This paper gives a critical analysis of the Charleston quake of 1886 with illustrations of its consequence for the region at the time and of what it means to the modern political, social and economic systems. The physical damages that the earthquake caused in the Charleston region include the displacement of large portions of tracks and curvy formations in addition to longitudinal land movements. In the region, more than 75 km of rail lines were also destroyed. Geographic malformations such as fissuring and craters were formed extensively in the region.3 These malformations indicate the powerful nature of the earthquake. Therefore, both economic and social implications were felt as a result of the earthquake, as revealed by the deaths of people, displacement and destruction of infrastructure which served to support the economy within this region. The regions surrounding Charleston also felt the impact of the earthquake which was experienced even more than 60 miles away. Other sources reported that structures were damaged as far as in Kentucky, Ohio and Alabama which are located hundreds of miles away for the region of Charleston. Toward the Northern Side, reports showed that the quake was experienced in Boston and New Orleans to the West.4 The extensive nature of the earthquake is illustrated by its reach and the geographical scale that it was measured to have reached. The measurement of the quake was estimated to have reached up to 7.3 as revealed in the Richter scale. The soil liquefaction which characterized this earthquake was recorded along the affected areas. It is said that there are minor quake activities in this region which have been recorded and measured by geologists in order to determine the possibility of a major quake happening again and the implications that would result from it. The minor activities of quakes experienced in the Charleston area have been attributed to the aftershocks of the 1886 quake. This implies that the major Charleston quake is being experienced up to the present days through in a smaller scale. The damaging Charleston earthquake has been explained by geologists as a consequence of the faults and malformations which occurred when the Pangaea was breaking. However, some scientists argue that there were less significant earthquakes which were experienced in the Charleston region and they would be attributed to the severity of the 1886 earthquake and the extensive damage which resulted out of it.5 The impli cations of geological studies and investigations of earthquakes in the present times are related to the fact that the faults of the Pangaea breaking may have future consequences in other parts of America such as the Northern coast. Because of the high magnitude of the Charleston Earthquake of 1886, it is an area of extensive study and investigation. As an example of an intra-plate earthquake, scientists and geologists study the Charleston quake with an aim of predicting the possibility of future experiences of such quakes. As a result of these studies, geographic and political implications of earthquakes have increasingly become significant in America.6 The severity of the Charleston quake was demonstrated by the widespread ejection of sand along the epicentral region. Geologists say

Analysis The lady with the petdog Essay Example | Topics and Well Written Essays - 1250 words

Analysis The lady with the petdog - Essay Example Their love is under the test of rationality and the lens of morality. Chekhov’s â€Å"The Lady with the Pet Dog† uses ambiguity, setting, characterization, and realism to suggest that love has no logic, explanation, and morality, but people continue to fight for it because it is the only thing that makes them truly happy. Love has no logic. Chekhov uses ambiguity in language to show that love does not make any sense. Gurov does not find his affairs satisfying in the long run. He just knows that he attracts women enough for them to â€Å"favor† him, including sexually favoring him (Chekhov par.5). These sexual favors are short and sweet, until his heart chooses to favor someone forever. Favor is an ambiguous word, whose final interests are unclear. In the story, favor motivates two married people to prioritize their self-interests, to the risk of breaking the laws of God and man. One more example shows ambiguity. After making love, Anna feels sorry for the affair. Chekhov describes her as a â€Å"Magdalene†¦by an old master† (par.39), perhaps even worse because she is not a prostitute, but she has given her married body to another married person. Her monologue, however, bores Gurov: â€Å"†¦he was irritated by her naive tone, by her repentance, so unexpected and out of place†¦Ã¢â‚¬  (Chekhov par.36). ... Aside from language, characterization enables Chekhov to demonstrate that people may be opposite in many ways, but love can still bind them. Gurov is old and a self-confessed womanizer, while Anna is young and inexperienced with affairs. They seem an unlikely pair, especially when they have some sense of â€Å"fear† for their spouses (Chekhov par.4). They fear them because they are with them, despite the absence of love. Furthermore, Gurov thinks that there is nothing special about him, while Anna finds him as the best kind of man. For Gurov, he is only an old man â€Å"almost twice her age,† but Anna sees him as â€Å"kind, exceptional, high-minded† (Chekhov par.58). Evidently, love has skewed their assessment of true identities. Their love blinded them of the ability to see each other’s worst faults. One of the greatest sources of the irrationality of their love is its depravity. Their affair is wrong but they want to continue anyway, even when at first, they are unsure of what they have. Anna becomes restless and cannot sleep (Chekhov par.52). These are signs of guilt. They are both married, but they are in love with each other, not their spouses. In addition, they are hesitant of what they have, until Anna leaves Gurov. When Anna sees â€Å"dew on the grass† (Chekhov par.49), it represents something new, the dawn of love. The dew is fresh and refreshing. Their love awakens their old grass. But the dew will evaporate at the light of day. The sun is their morality. Their dew is against this morality, and it is illogical to continue it. They are struggling to hide their love, when they can always end it to conclude their miseries (Chekhov par.52). They feel â€Å"dread† (Chekhov par.52) of being caught, being judged. Why suffer these complications? They

Control Of A Switched Reluctance Motor Engineering Essay

Control Of A Switched Reluctance Motor Engineering Essay The main objective of this chapter is to spot the light on the practical performance of some form of control on an actual switched reluctance motor in preference to merely theoretical method including simulation and modelling. Moreover, the design of the controller involves reducing the noise. The crucial motivation for this is to enhance new expertise, sensibly regarding circuit design and construction the use of a Programmable interface controller (PIC). A switched reluctance motor (SRM) has been appeared since the nineteenth century, but the renewal of this motor has been to discover a high-power switched device [13]. The earlier motor was facing a controversial issue in their control where the power electronic switching was very expensive and has many drawbacks. The Switched Reluctance Motor (SRM) is an electromagnetic, rotary machine in which torque is produced by the tendency of its movable part to move to a position where the inductance of the excited winding is maximized [12]. Furthermore, (SRM) has been proposed for variable speed applications [13]. In general a salient-pole synchronous machine without field excitation or permanent magnet is called a reluctance machine. From the general definition (SRM) is classified as a synchronous machine, but has different construction. These differences are both stator and rotor have salient poles. However, the stator has wound field coils but the rotor has no coils or permanent magnet. Moreover, the stator has higher number of poles or (tooth) than the rotor. While each pole in the rotor is excited by the opposite pole in the stator due to a sequence of current pulses which produce magnetic field on each stator poles. The Switched Reluctance Motor (SRM) can be more capable for variable speed than AC and DC motor. Since it is simple, robust, has a high efficiency and high power density [3, 10, 12]. Figure 1.1: two- two poles SRM [12] Over the past 30 years the power electronics growth has made the exploit of the characteristics of reluctance machines sufficiently well. Consequently, several successful products are now manufactured. The rotation of the motor depends on the angle between the rotor poles and the stator poles where the current is switched on or off to each poles in the stator where the position of the rotor is very significant. For the motoring principle example, two- two poles (SRM) where stator has two poles with two wound field coils connected in series and two poles in the rotor without magnets or windings and free to rotate as it shown in figure 1.1. If the rotor poles edge is started to be aligned, the current is switched on. Consequently, the inductance is increased and the torque in the rotor is occurred to pull the rotor in clockwise direction. The direction of the rotation is addressed by the current. The current is switched off; when the rotor poles are fully aligned with the stator poles that make the rotor free to move. However, if the current is not switched off the torque at the fully aligned is become negative that produces an attraction between the poles where the negative torque and positive torque cancel each other [12]. The ideal current waveform is therefore a series of pulses synchronized with the rising inductance intervals. The cycle of torque production associated with one current pulse is called a stroke.[12] As a result, to increase the resolution more teeth can be add to the stator and the rotor. From the instantaneous electromagnet torque equation which was derived by T.J.E.Miller(2001) [12] Te = i2/2 dL/dÃŽÂ ¸ that shows the torque is proportional to the square of the current. Therefore, the current is always unipolar. However, at the end of each stoke the voltage must be reversed to return the flux linkage to zero. The power switching IGBT, GTO and MOSFET or any other switching devices can be used in the power electronic topologies [3]. These switches are used to open and close the exiting power in the stator winding. 1.5. Applications of SRM Since the SRM has a significant characteristic operation and design which shows many advantages and makes them suitable for various applications. R.Krishnan (2001) [10] shows the wide range of applications. For example, plotter drive, air-handler motor drive, hand fork lift/ pallet truck motor drive, door actuator and washers and dryers machine, those applications are low power applications where the drives are less than 3hp. Moreover, the medium power applications range is less than 300kw such as industrial general purpose drive, train air conditioning drive and mining drive. However, the SRM did not find much attention by the manufacturers in this range of power. The high power drives are still under study for drives up to 1000hp for fan and pump applications where the converter is very competitive. The high speed applications such as screw rotary compressor drives, centrifuge for medical applications, and aerospace applications the SRM is a perfect option for them due to the small size of the rotor and high power density. Some efforts of study are in Mild Hybrid Vehicles that is reported by (Watterson, P.A. ; et al) [17] in 2008. 1.6 Research area Since the SRM has appeared and has disadvantages such as reduction of acoustic noise and torque ripple. According to the noise and vibration sources can be classified into four main categories: magnetic, mechanical, aerodynamic, and electronic. The classification was done by R.Krishnan (2001) [10] as it shows in figure 1.2. Most researches are based on the design of the motor or in the controller to improve the motor performers and reduce the noise. Iqbal Husain (1994) [8] discusses the effect of the high ripple toque which causes vibration and acoustic noise. The case was in driving SRM for low speed and high performance applications by a new PWM strategy current control. The method was based on optimum profiling of the phase current during an extended overlapping conduction period of two phases. The result shows a smooth operation with minimum torque pulsations by controlling the current profiling. Moreover, other studies were in magnetic radial force as M. N. Anwar (2000) [1] show s the lower noise is occurred when the dominant mode frequencies is high. As a result the research has experimented a proposed design considerations to a 4-phase, 8/6 (1-repetition) and a 3-phase, 12/8 (2-repetition) 1.0 kW SRM with low acoustic noise requirement. The results of the proposal design shows that the noise level has been reduced; however, a 3-phase SRM is noisier than a 4-phase SRM. There are other research was on reducing the noise by Adding extra winding to the phase winding to reduce magnetic stress during commutations with Two stage power converter. Adding extra winding to the phase winding in 6/4 SRM with Two stage power converter shows a significant improvement in the efficiency and reduce in the vibration and noise [16]. The electronic sources of noise occur by reason of the harmonics of voltage and current. The significant research is reported by (Lecointe J.P; et al) in (2004) [11]. The research was in adding an auxiliary winding to the model of a BDFRM (brus hless doubly-fed reluctance machine) to shows that the additional winding has a benefit in reducing the noise in SRMs where a specially derived current is injected to create a suppression force. The BDFRM is used to analyse the equivalent circuit where the equivalent circuit of the model is similar to SRM. However, the process still needs to be complete using two current sources. Figure 1.2: sources of noise in electrical machines [10] Advantages and disadvantages of 3 basic power electronic circuits There are many power electronic topologies that is used for SRM depends on the machine phase configurations. R. Krishnan (2001) [10], figure 1.3, has classified the power converters for switched reluctance machines. The simple three topologies are: Figure 1.3: Classification of power converters for SRM [10] 1.7.1. Single-Switch-per-Phase Circuits (Split dc supply converter) The basic operation of this topology, figure 1.4, is to split the reverse dc power supply into two capacitors. The phase voltage is half the dc voltage when the switch is on and negative half voltage when the switch is off. Consequently, this configuration is a disadvantage. Moreover, the maximum speed and the output power are half the rated while the current and the voltage are half. This topology is only used for low-cost application due to the high power losses. However, the advantages of this topology are: simple and less cost. [3, 10] Figure 1.4: Single-Switch-per-Phase Circuits (Split dc supply converter) [10] 1.7.2. Single-Switch-per-Phase Circuits (Bifilar type) The basic operation of this topology uses a bifilar winding, figure 1.5, with the motor winding to regenerate the stored energy to the supply that the phase winding is connected in series with the switch, and the diode is connected in series with the bifilar winding. The reflected energy is an advantage for this topology in some applications, where the transistor voltage is much higher than the supply voltage. However, the cost increases as the extra winding is added to the motor and the complex design of the power electronic. Moreover, the power density of the motor reduces because of the bifilar winding. [3,10] Figure 1.5: Single-Switch-per-Phase Circuits (Bifilar type) [10] 1.7.3. Two-switch/phase Asymmetric Bridge Converter From the half bridge topology that is illustrated in figure 1.6. if both Q1 and Q2 are turned on the apply voltage at the winding is equal to the supply voltage. However, if both Q1 and Q2 are turned off the apply voltage at the winding is equal to a negative supply voltage where D1 and D2 to avoid the freewheel currents. The advantages of this topology that it can give a negative voltage to reduce the torque ripple refer to noise for a high performance SRM drive system and it can be used for generator or motor operations. The disadvantages more control is needed, more fault in the switching [3, 10, 12]. Figure 1.6: Two Switched / Phase Asymmetric Bridge Converter [12] 1.8 Speed and Position Controller The switched-reluctance motor is basic control system form of a torque-controlled drive as compared in performance to a D.C motor (separately-excited). Commonly, controlled speed or even position is the most requirements. The SR motors speed increases if torque is still produced. As the D.C. drive the torque of SR motor controller is included within a speed regulating loop. The rotor position sensor, which is the encoder, is used as a feedback to derive the speed of the motor readily as it shown in figure 1.7. From the figure it can be seen that an additional feedback is introduced to achieve the position control of the SRM [3]. Figure 1. 7: basic speed and position controller for SRM [3] Aims and Objectives The aims of the project are to design, build and test a power electronic circuit for Switched Reluctance motor (SRM) using Bifilar type. The objectives are as following: Understand the operation of two- two poles SRM to realise the behavior of the motor and their characteristic. We can know from their characteristic how to make the motor spin and the control techniques that is used for them. Select and Design Power Electronic Circuit can help to active a high efficiency, low noise and low cost. Test Power Electronic Circuit with Resistive Load: to find the advantages and disadvantages of the circuit when the resistive load is applied to the motor. Design, Build and Test current limiting circuit where the current limitation can achieve low torque rebel. From the low torque rebel the noise can be decrease. Rotate motor using direct feedback where the position of the rotor is important to detect the moment of switching on and off. Study and understand PIC 18F 46K20. Program PIC to control SR Motor by designing a simulation using the MATLAB or other programmes. Chapter 2 Choosing power electronic component 2. Overview Over the time motor control has a significant growth in the industrial control where digital signal processors together with external hardware and appropriate software are used widely. In order to control the motor the switching device should switch on and off according to the position of the motor rotor and the apply current to the stator winding. The aim of this chapter is to highlight the details of the components that were used in the controller design. 2.1 Technical operation of Simple SRM The simple SRM has 2 poles in the stator and 2 poles in the rotor, figure 1 which the stator iron core has square shape with two winding in the upper side opposite the poles. Both stator and rotor are salient poles where the free spinning rotor is placed between the stator poles. In order to spin the rotor, stator poles are energised by the winding when the rotor poles are unaligned with stator poles. The inductance increased and the torque is produced as the rotor approaches the aligned. At this point the stator winding is demagnetised allows the rotor free to spin. The time of the energised and de-energised of the motor windings depend on the rotor speed. Figure 2.1: (a) Simple SRM 2/2 poles with bifilar winding[12] 2.3 Winding connections The motor has a bifilar winding to build up the current in the stator quickly, figure 1, which facilitates the higher torque and magnetic flux densities occurring. As a result the stored energy regenerated to the supply that the phase winding is connected in series with the switch device. This leaded to three achievable connections, figure 2, for bifilar winding. Figure 2.2: Possible winding connections The first connection shows the parallel connection that has a resistance connected in parallel to the motor windings to reduce the power losses when the switch is off. This connection has the main disadvantage due to the high loss. The second connection shows series connection that two switching devises are used which increase the cost of the design. However, this topology is the most common one for SRM according to reduce the switching heat losses, protections and their control flexibility that is handling the phase current and the machines acoustic noise. The third connection is the most cost effective and easier to control for the simple SRM figure 2. Moreover, it is offering the zero voltage supply as a reference for all power switching that make it suitable for low- voltage systems. Simply this configuration operates as it shows in figure 2.3, When the current of phase-A is turned off by removing the base drive signal to T1, the induced EMF in the winding is of such polarity that D1 is forward biased. This leads to the circulation of current through D1, the bifilar secondary winding, and the source, thus transferring energy from the machine winding to the source. The various timing waveforms of the circuit are shown in Figure 2.3. During current turn-off, the applied voltage across the bifilar secondary winding is equal to the dc link voltage. The voltage reflected into the main winding is dependent upon the turns ratio of the windings. Considering the turns ratio between the main winding in series with the power switch and the aux iliary winding in series with the diode as a, the voltage across the power switch is VT 1 = Vdc + aVdc =(1 + a)Vdc This shows that the voltage across T1 can be very much greater than the source voltage. One switch per phase comes with a voltage penalty on the switch. The volt ampere (VA) capability of the switch will not be very different for one switch compared to two switches per phase circuit. [10] Figure 2.3: (a) Converter for an SRM with bifilar windings; (b) operational waveforms of bifilar converter. [10] Thus, Figure 4 shows the primary plan for designing the current limiting circuit for the third connection of SRM and each block are explained next. Figure 2.4 basic configurations for current limiting 2.4. Power switching component Nowadays semiconductor and electronic switching devices offer a significant performance to control the electrical motors. Moreover, their size and cost make them more convenient to use in the motor control. The electronic devices has a significant role to control SRM where the switching on and off for the voltage is the major role to control the SRM with high performance. As a result, the main electronic devices that can be used are field effect transistors. There are two types of the field-effect transistor J-FET and MOSFET (see the appendix figure 3) [4]. The MOSFET has taken a widely role as a best choice to the simple SRM for many reasons that is discussed later in this chapter. 2.4.1 N-channel power MOSFET (STP36NF06) Simply the MOSFET is a metal-oxide-semiconductor field effect transistor where the MSFET has a significant characteristic [2]. The characteristic of N-channel MOSFET shows a significant use in switching. The structures of the MOSFET are shown in figure 5 where the MOSFET consist of Si P material substrate, two N material substrate that one is the source and the other is drain, and between them there is an insulator Sio2 and at the top metal conductor which is known as a gate. The length (L) below the gate and between the source and the drain is known as a channel. Fundamentally, the MOSFET output current is proportional to the charge in the semiconductor material by the control electrode[15]. Figure 5 MSFET structures [6] The MOSFET is used as a switching device to provide a high speed switching. The significant advantages of the field-effect transistor are: Higher operation temperature. Lower switching leakage. High input impedance. Low noise. Lower power dissipation during switching. In addition, The N-channel MOSFET has advantages such as ease to use for high frequency switching and simpler to control where the MOSFET gate drive do not require a continuous current to switch ON. When the MOSFET is needed to switch ON positive threshold voltage is needed to apply to the gate drive and Zero current to completely switch off. Moreover, the N-channel MOSFET has higher density integration and possible in rapid reduction in capacitances. [2]. MOSFET (STP36NF06) gate requires drive properly the later components are used to limit the current and the gate signal for the MOSFET. The gate drive is a power amplifier that accepts a low power input from a controller devices and generate the appropriate high current gate drive for a power MOSFET[4]. 2.5. Bipolar junction Transistor Transistors are considered one of the main elements of semiconductors that have been discovered in modern times. Transistors are used in the amplifiers of electrical signals and electronic switching, which have helped a number of factors such as small size, ease in manufacturing, cost effective and consume less power to extend significantly. Figure 2.6 (a) transistor structures (b) npn and pnp structures 2.5.1. ZTX 653 NPN transistor The NPN transistor is a type of bipolar transistors known as a medium power transistor. The NPN ZTX 653 transistor has interesting features that make it suitable for the push pull topology and amplifier topology (pre totem pole connections). The features of NPN ZTX 653 transistor are [6] * 100 Volt VCEO * 2 Amp continuous current * Low saturation voltage * Ptot=1 Watt 5.5.2. ZTX 753 PNP transistor The PNP transistor is another type of bipolar transistors that is used in the push pull topology. The PNP ZTX 753 transistor is suitable to employ in the push pull topology (Totem Pole) according to their features. Their features are [6] * 100 Volt VCEO * 2 Amp continuous current * Low saturation voltage * Ptot=1 Watt Figure 2.7: npn and pnp characters 2.5.3 Gate drivers (Totem Pole) This type of connection is known as a discrete drivers or push pull drives which is in common use today. Figure 2.8 shows the complimentary arrangement pair bipolar NPN and PNP emitter configuration. Moreover, the N-channel and P-channel MOSFT can be employing for totem pole connection. However, the N-channel and P-channel MOSFT driver suffers from shoot through current, caused by the threshold voltage overlap during ON and OFF transitions, resulting in increased drive power requirements [9]. Figure 2.8: push pull configuration The bipolar Totem Pole, figure 2.8, is non-inverting and offers no voltage gain to improve the pre-driver rise or fall times. It does provide current gain to reduce the driver impedance to speed the charge and discharge of the device capacitances. Once the input capacitances are charged and the power device has been switched, the driver does not require holding current. It has medium speed and does not perform well at higher conversion frequencies [9]. This circuit uses a complementary pair of transistors similar betas and power rating one is an npn power Darlington, and the other is a pnp power Darlington. When a high voltage (e.g., +15 V) is applied to the input, the upper transistor (npn) conducts, allowing current to pass from the positive supply through the motor and into ground. If a low voltage (0 V) is applied to the input, the lower transistor (pnp) conducts, allowing current to pass through the MOSFET gate from ground into the negative supply terminal.[14] 2.5.4. Common emitter amplifier (inverter) This configuration is a simple electronic circuit that is used to boost and invert the low signal. Figure 2.9 shows the circuit that contain a high resistance value with NPN transistor. The low signal is switch on and off the transistor where the resistance is limiting the current that apply to the transistor. This topology is used to boost and invert the output of signal processing unit to appropriate the signal that can switch the MOSFET as it will be discussed in the following point. Figure 2.9 common emitter configuration 2.6. Current control and limiting The winding current is controlled inorder to be not more than 8A. When the MOSFET is switched ON without any current limiting circuit, the current shoots up without any control. As a result, the technique for current limiting is arranged as follows When the winding current is less than 8A the MOSFET switches ON. When the winding current is exceeds 8A the MOSFET switches OFF. Therefore for appropriate current control, square wave signal is applied to the gate of the MOSFET. The frequency of input signal at the gate of the MOSFET is take into account to make the MOSFET switch properly with regard to the above current control arrangement. In order to do that feedback from the source of the MOSFET is carried to non-inverting terminal of the comparator. Figure 10 shows the operational waveform of the MOSFET. It can be seen that, the MOSFET needs to switch off when the voltage at inverting input of the comparator reaches 0.8V and switch on when the voltage is zero. Moreover, the reference voltage is 0.8 volt from the voltage divider law when a 0.1ÃŽÂ © resistance is connected to the source of the MOSFET. The 555 timer can offer the control of MOSFETs switching frequency. Figure 2.10: the expected waveforms from the design. 2.6.1 Timer NE555P The 555 timer IC is an incredibly useful precision timer that can act as either a timer or an oscillator. In timer mode is known as monostable mode the 555 simply acts as a one-shot timer; when a trigger voltage is applied to its trigger lead, the chips output goes from low to high for a duration set by an external RC circuit. In oscillator mode is known as astable mode the 555 acts as a rectangular-wave generator whose output waveform (low duration, high duration, frequency, etc.) can be adjusted by means of two external RC charge/discharge circuits.[14] In this project the monstable circuit is highlighted due to it has one stable state. Figure 2.11 (a) monostable configuration of timer 555 (b) monostable operations[14] In the monostable configuration, figure 2.11(before a trigger pulse is applied) the 555s output is low, while the discharge transistor in on, shorting pin 7 to ground and keeping C discharged. Also, pin 2 is normally held high by the 10-k pull-up resistor. Now, when a negative-going trigger pulse (less than 1à ¢Ã‚ Ã¢â‚¬Å¾3VCC) is applied to pin 2, comparator 2 is forced high, which sets the flip-flops Q_ to low, making the output high (due to the inverting buffer), while turning off the discharge transistor. This allows C to charge up via R1 from 0 V toward VCC. However, when the voltage across the capacitor reaches 2à ¢Ã‚ Ã¢â‚¬Å¾3VCC, comparator 1s output goes high, resetting the flip-flop and making the output low, while turning on the discharge transistor, allowing the capacitor to quickly discharge toward 0 V. The output will be held in this stable state (low) until another trigger is applied [14]. According to the operation of the monstable the pulse width can be modified by changing the value of R1 and C. T= 1.11 R1C Thus, to obtain capable functioning of the circuit the variable resistance R1 with a maximum value 100KÃŽÂ © and the threshold capacitance C value is 100nf are chosen. The timer input is the output of the comparator where the two values of the voltage are compared to make the output of the timer based on these two values. The two voltages are one is 5V and the other is the feedback from the MOSFETs source. 2.6.2. (LM393) Comparator The comparator is used to compare the voltage between the source voltage and the feedback from the MOSFET. This is important to control the current by triggering the timer to limit the current as it is mentioned before. LM393 has several advantages for timer input which are Higher accuracy in comparators. High voltage range (2.0V to 36V) Biasing with lower input current. Lower input offset current  ±5 nA Figure 2.12 LM393 connections to the circuit In order to establish the reference voltage variable resistance is required in the voltage dividers law. The operation of the comparator is simply as follows If IN+ > IN- the comparator output = V8. If IN+ From the previous operation it can be seen that the comparator send the signal to trigger the input of the timer and the timer acts upon the applied signal therefore the MOSFET switches on and off with regard to the timer output. However, the output of the timer switches on the MOSFET when the current is high which will be disastrous to the motor. To avoid this not to happen, a design of logic gates are incorporated in the current limiting topology of the SRM. 2.6. 3. Logic gate design (SN74LS00N) Logic gate is designed according to the output of the timer which gives the positive pulses when the current exceeds to 8A and no pulse when the current is less than 8A. With the purpose of switch (totem pole) the gate of the MOSFET turns on and off at required instants of time using an external Drive Signal. Figure 2.13 shows the technique of the combination between the Drive Signal and the timer output to control the MOSFET. SN74LS00N has four NAND gates that can be used to reduce the number of ICs in PCB connection. The logic gate is connected to the timer output which will be inverted with a common emitter configuration to switch on the MOSFET when the timer output is low (Itimer Figure 2.13: (a) SN74LS00N chip (b) logic circuit connection (c) NAND gate logic signal. The MOSFET behaviour that is need according to the timer output is shown in table 1. To do that the NOT gate, OR gate and AND gate are needed before the pre totem pole connections (common ammeter topology).
