Raditation essays

Raditation essays Radiation therapy is a very effective way to treat and kill cancer cells. Its a treatment that can be treated in combination with other forms of treatment like surgery and chemotherapy. The high doses of radiation kill cancer and shrink tumours. Radiation therapy can either be given externally by an external beam of radiation or through internal radiation. The newest developments in the treatment of lymphoma uses drugs called monoclonal antibodies that have a radioactive component. It attacks a protein on the surface of a cancer cell and destroys the cell. This is an example of internal radiation therapy. Radioactive substances used in radiation therapy are cesium(137 Cr), Yttrium (90 Y), Cobalt (60 Co), Iodine (131 I), Phosphorus (32 P),Palladium (109 Pd), Gold (198 Au), and Iridium (192 Ir). Some side effects from radiation therapy is fatigue, malais, low blood counts, difficulty or pain in swallowing, skin pain, increased skin pigment, anorexia, nausea, vomiting, hair loss, a nd increased susceptibility. Radiation used for cancer treatment is called ionizing radiation because it forms ions as it passes through tissues and dislodges electrons form atoms. There are about 4 types of radiation used. One type is called high-energy photon, which is from radiation active sources like cobalt, cesium or a machine called a linear accelerator. Another type is the electron beams that provide superficial treatment and avoids radiation to deeper tissue. A third type is Proton radiation that causes little damage to tissue but is very effective in killing the cancerous cells. And the fourth type is neutron radiation that is used for some cancers of the head, neck and prostate.In the treatment of the thyroid ablation is the administration of 131 Iodine orally in a liquid capsule. The 131 Iodine emits both negative beta particles and a prominent 364 keV gamma proton. The beta particles delivers the major dose to the remnant thyroide penet...

How to Get Good Grades in High School

How to Get Good Grades in High School SAT / ACT Prep Online Guides and Tips The transition to high school causes academic whiplash for many students. It’s hard to adapt to a new environment and get good grades when you’re given more independence in your assignments and are expected to learn more challenging materials. In this guide, I’ll go through the most important strategies that will help you to get good grades in high school and beyond. Basic Academic Survival Strategies Let's start with the most fundamental strategies for getting good grades. A strong foundation is the key to success! Strategy #1: Read Directions and Rubrics Carefully Read the directions thoroughly on every assignment you get.If you don’t follow the directions, you won’t get a good grade even if what you do would be considered solid work on a slightly different project.If your teacher tells you to write a seven-page essay, and you only write five, you'll get points taken off even if you do a good job. Don't sacrifice your grade just because you were careless or chose to ignore the instructions! Sometimes when students misinterpret directions, they blame the teacher for giving them a bad grade.Even if you disagree with the structure of an assignment, being stubborn about it probably won’t get you anywhere.You should re-educate yourself on the expectations for the class so that you don’t give the teacher another chance to deduct points from your assignments.In these cases, you’re probably just dealing with a strict teacher who likes to stick to very specific guidelines.Once you know what the his or her standards are, you will be able to reliably earn high grades. Strategy #2: Listen and Participate in Class A trait that is consistent in people who get good grades is that they pay attention in class.You may think that you can just space out in class, study hard later, and ace the test. If school has always been a breeze for you, this might be true up to a point, but it will catch up with you when you run into something that isn’t as easy to understand. If you pay attention in class, you’ll spend less time studying in the long run.Why is this? It’s because you’ve already absorbed a lot of the information you need to know just by being engaged while your teacher is talking. You can even go a step farther and take notes in class to reinforce what you’re learning in a different way. It's smart to get into this habit before college so that you don’t struggle with note taking in lecture classes. If you learn how to summarize the main points of a lesson now, it will be easier for you to take notes at times when they’re even more critical. Class participation is another big part of this.Participation is important for a couple of reasons.First and foremost, it might be a part of your grade! In some cases, class participation accounts for ten percent or more of your final grade.Even if it isn't a part of your grade, participating in class will help you understand the material more thoroughly and let the teacher know that you care about the subject. For me, class participation was always very difficult because I was shy and afraid that I would say the wrong thing. If you have this issue, I would recommend sitting as close to the front of the classroom as possible so that it feels like you’re just talking to the teacher and not addressing the whole class. Also, try not to overthink it! I can’t tell you how many times I had an answer in my head that I decided was dumb only to hear someone else say it thirty seconds later. Even if your answer is incorrect, you should view it as a learning opportunity that may help you to understand the material better. This is what your face should look like in class. If you're extra creepy, your teacher will be afraid to give you bad grades. Strategy #3: Ask for Help Sooner Rather Than Later Often, the key to success is knowing when to ask for help, and high school classes are no exception.If you don’t understand a concept, don’t wait until you’ve already bombed a test to get help.Approach your teacher as soon as possible, and ask if he or she would be willing to meet you after school to go over the material.By doing this, you can avoid bad grades before they happen and build a positive relationship with your teacher. Of course, all of this is easier said than done. It's hard to ask for help if your teacher is less friendly or you’re a super independent person.If you’re worried about approaching your teacher, stick to a script. You can just say â€Å"Teacher’s Name, I’m having some difficulty understanding this unit. I was wondering if you might be able to talk through the main concepts with me after school at some point. I’ll come up with a list of my questions.† If you prepare a list of questions for your teacher, it will be easier for you to get the information you need and for your teacher to explain things in a way that is helpful to you.You should also remember that there’s absolutely no shame in asking for help.It’s really the smartest thing you can do if you’re struggling, and it will only lead to better grades in the future. Strategy #4: Don’t Rely on Your Family and Friends Too Much Another way of saying this is â€Å"don’t cheat,† but sometimes the definition of cheating can be nebulous.If you and your friends help each other on a homework assignment, that’s probably fine depending on the distribution of work.However, if you directly copy a friend’s homework (even if they say it’s ok), it’s definitely a form of cheating whether or not the homework counts toward your grade. Avoid doing this, especially if you want to get good grades in the long term.If you copy your friends’ homework assignments, you’re committing self-sabotage.I know it’s a cliche that you only hurt yourself by cheating, but in this case it's true.If you rely too heavily on the knowledge of others for small assignments, larger assignments like tests and papers will be even more difficult since you never learned the material for yourself. Also, don't let your parents edit your papers extensively or do the bulk of the work in figuring out homework problems.They probably mean well, but it will do you more harm than good if you’re not learning on your own terms.Eventually, you’ll have to write an essay or solve math problems on a test, and you may fall short of your potential if you don't have experience doing these things independently. Matching jackets? Kind of cute and kind of lame. Matching homework? Unambiguously lame. Expert Study Strategies Many students have trouble getting good grades in high school because they don't know how to study effectively. Here are a few of the best ways to improve your test scores through the use of smart study strategies. Strategy #5: Always Do the Homework (Even If It Doesn’t Count!) Most teachers in high school assign regular homework, although some may not check it or incorporate it directly into your grade.Some students view this as a free pass to ignore homework assignments, which can is a very bad idea.In subjects like math and science in particular, homework assignments are critical if you want to gain full comprehension of the material.In math, your understanding of one unit of study is often a necessary foundation for your understanding of the next unit.Knowledge builds on itself. If you start skipping homework assignments, you may get confused when the teacher moves on to a new unit.Ultimately, you could become completely lost and perform poorly on assignments that do count towards your grade. Doing homework assignments will also help you psychologically. If you’re staying on top of things in a class, you'll be more confident in your knowledge.Homework assignments are a way of studying consistently over time. If you do the homework, you may not have to study as much for tests because you’ll already have a solid understanding of what you need to know. This is what will happen on tests if you don't have a strong homework-based foundation of knowledge. Strategy #6: Know the Difference Between Reading It Over and â€Å"Getting It† Just reading over the material before a test won't cut it unless you have a photographic memory. You need toactively absorb the information, not just skim over it and hope it will stick in your brain. Surface-level knowledge won't help you, especially when you're dealing with open-ended questions on a test. You should be able to recall the facts without any hints or prompting. If you have review sheets to study before a test, I would recommend reading them in small, manageable sections.After you read each section carefully, look away from it and see if you can repeat the facts back to yourself.Don’t move on from a section until you’re able to do this. One thing that I’ve found very helpful in cases like this is to make up some sort of weird mnemonic. It can be an acronym or just something memorable that has a random association with the information you need to know.The more bizarre the memory device you come up with, the more likely you are to remember the facts. After you’ve read everything over yourself and feel relatively confident, you can have someone else step in and quiz you on the information.To be sure that you have a full understanding of what you need to know, you should be able to answer questions about how different facts connect to each other rather than just regurgitating the facts themselves.For example, if you’re studying for a history test, you might have someone ask you a question like â€Å"what were the main factors that led to the French Revolution† that requires you to draw from a few distinct facts to reach a separate conclusion. Strategy #7: Study Between Tests, Don’t Cram There is a certain glamour for some students in the late-night pre-test cram session.However, sacrificing your sleep and sanity will not get you a better grade on the test (no matter how much cooler it might be than planning ahead). The best way to ensure that you don’t panic before a test (or on the test itself) is to make a habit of going over the material that you’ve learned regularly and not just when it gets down to the wire.You’ll retain it better, and you’ll get a good night’s sleep to recharge your brain. In the week before a big test, you can study for an hour or so every night rather than studying for five hours the night before.As you build up your knowledge, you’ll feel more and more confident.On the night before the test, instead of trying to study every little detail that you need to know, you can do a quick review of the main concepts to reassure yourself that you’re in good shape. If studying responsibly is too uncool for you, try getting a good night's sleep while wearing sunglasses to keep up the illusion of detached nonchalance. Strategies for Structuring Your Work Strategy #8: Make Project Timelines (Don’t Procrastinate!) If you hope to earn high grades without suffering from excessive amounts of stress, you must overcome your procrastination habits.It's especially hard to manage your time responsibly on long-term projects. It may seem like you have forever to complete the assignment, but time will always catch up with you. If you're a procrastinator, I highly recommend making a timeline whenever you get a long-term assignment. If you have a project that’s due in a month, set aside the first week for brainstorming, make a rough outline of the project in the second week, flesh it out as much as possible in the third week, and spend the rest of your time perfecting it.This is a vague timeline because it depends on the type of project you’re doing and what it involves, but you get the idea. If you save the last week for polishing your work and fixing mistakes, you’ll end up with a final product that’s a much better representation of your abilities.Sticking to a schedule like this can be tough, so you might want to ask your teacher to help monitor your progress by checking in with you periodically.Some teachers already set up checkpoints for longer term projects because they know students have trouble avoiding procrastination.If this is the case, stick to the schedule and avoid falling behind! Strategy #9: Stay Organized Many of these tips will be useless if you don’t keep track of all the materials for your classes.Cultivating good organizational habits will not only help you succeed in high school; it will pay off in spades when you get to college as well. Always mark the beginning of each new unit in your notebook, and keep a binder or folder for each class.This way, when you study for tests, you won’t be freaking out about where a certain review sheet went or why there seems to be nothing relevant in your notebook.Avoid just throwing papers into your backpack. I’ve made the mistake of doing this many times in the past, and you WILL forget where you put them when you need them most. It's also a good idea to write down your homework assignments in an agenda book so that you don’t miss anything.It’s easy to forget about smaller assignments if your brain is focused on a big project or test that’s coming up.Even if you don’t have a concrete homework assignment in every class, you should make note ofany potential work you might do that night. If you have light assignments in your other classes, this will remind you to catch up on a long term project or start studying a bit for a test that’s coming up in a week.

When DIY Bites You in the Butt

When DIY Bites You in the Butt We are an industrious lot. We want to know how someone did what he did successfully, so we can do it, too . . . or do it better. Or do it ourselves instead of buying the other guys product. Or do it ourselves to save money . . . or to maintain creativity as our own instead of splitting its ownership. Its called DIY, or do-it-yourself, and we cant stand not to try doing it ourselves if it means more benefits for us. I love to bake. I hate recipes that have boxed mixes or tell me to save time As writers, we fight that battle uphill to publish a book. How hard can it be to format that manuscript in Word? How difficult can a cover be? Surely I can learn how to upload books. We read directions, study what others have done, then grit our teeth, determined to do it ourselves. Then invariably, after weve erred, redone and cursed our mistakes, we reach a point where we ask ourselves and our friends: It doesnt look bad for me doing it myself, does it? And right there youve compromised your storys future. Youve cobbled together what others do for a living. Youve decided to settle for less than professional. You think others wont notice, because they havent learned what youve learned, and tried what youve tried. When youve poured your soul into writing, you need to equally pour your soul into its proper publication. You have two choices when doing anything in life: 1) Take the time to become an expert at it, or 2) Hire the expert. Just know that anything in between is settling. When it comes to baking a cake, Ill settle for my Milky Way Cake from scratch. Its meant to be rustic, gooey and not exactly straight around the edges. But when I need a cake for someones 50th anniversary, believe me, Im hiring someone wholl give me the presentation needed to respect the grand auspiciousness of the occasion.

Being a leader is not easy Essay Example | Topics and Well Written Essays - 2750 words

Being a leader is not easy - Essay Example "Nothing matters more in winning than getting the right people on the field. Differentiation helps you do that." (Welch Way, 29 March 2009). One of the biggest challenges faced by the leaders these days is getting the right people for the job, any job can be completed by anybody but the point is how efficiently a person can do a job Leadership is all about perfection and any wrong decisions taken can prove very fatal. For instance a leader hires a person, who he believes is the right man/woman for the organization but the work of that employee proves otherwise, the organization can suffer because of the same and the loss occurred because of that wrong decision of the leader will always remain irrecoverable. It is very difficult these days to find the right people, who can commit their future to the organization but leaders are expected to have the quality of differentiation, a leader who possesses this quality can never go wrong in the process of selecting the right people for the or ganization. ... This is one of the biggest challenges which the leaders these days face, if a leader is born with this quality then major pitfalls in leadership can be avoided without facing much difficulty. The managers need to take up multiple roles and this will ensure the satisfaction of many demands. Henry Mintzberg has given a comprehensive guideline which consists of ten roles that are common to the work done by all managers. These roles are further divided into groups, interpersonal, informational, and decisional. The role of information ensures that every manager is aware of what the other manager is doing. The interpersonal role is largely responsible for providing the information and ensuring that every manager is well aware of what is going around them. The decision role makes use of the information provided by the interpersonal role and the process of decision making starts. The performance of managerial roles and the requirements of these roles is usually played at different times by the same manager and to different degrees and it depends on the level and function of management. The ten roles are described individually, but they form an integrated whole." (Henry Mintzberg , 29 March 2009). Another big challenge which the leaders of today face is the daunting task of decision making. Decision making is the most challenging task for any leader. One wrong decision can change many things around in an organization and those changes will surely be for the worse of the organization on the other hand one good decision can help the organization in more ways than one. Decision making is a very delicate process, numerous things have to be kept in mind, a leader just cannot go on making wrong decisions because that would result in disaster,

Financial Decision - Making Assignment Example | Topics and Well Written Essays - 2000 words

Financial Decision - Making - Assignment Example For example, it would not have enough cash to pay creditors the 180,000 due in October, to pay the salaries of staff on time until perhaps January 2007 when a cash inflow of over 1 million is expected, and even to pay its promotional expenses. Note from Table 1 that the 42,000 depreciation, since it is not a cash transaction, is not included in the cash forecast as an outflow from the business during the period. The beginning cash balance includes the 30,000 in cash on 30 September 2006. The beginning and end balances reflect the cash balances at the start and end of the month. If the cash forecast showed a negative amount, how could there be a net profit at the end of the period The answer is that the Profit and Loss (P&L) Report captures the business activity during the period, which is profitable (note the gross and net profit margins of 6.3 and 4.6 percent respectively). The cost of sales includes payments for activities required to generate the sale, to which we add agents' commissions, direct (flight and hotel) and variable costs, administrative overhead, and penalties if booking target volumes of 10,000 holidays are not reached. Two cash transactions are not in the P&L because they refer to past business activities (like paying a 180,000 loan in October 2006 and the 20,000 principal for a previous loan by March 2007) or investments (fixed asset investment of 50,000 in March 2007) that will generate returns over the coming years. Loan repayments and investments in fixed assets are balance sheet transactions and not included in the P&L. The Balance Sheet as in Table 3 before adjustments on 31 March 2007 is as follows: Summary from Table 3 BALANCE SHEET 31-Mar-07 30-Sep-06 Fixed Assets 568,000 560,000 Current Assets (40,000) 30,000 Trade Creditors 0 (180,000) Loans (90,000) (110,000) Total net assets: 438,000 300,000 Share capital 100,000 100,000 Reserves 200,000 200,000 Profit and Loss 138,000 Total shareholders funds: 438,000 300,000 The balance sheet includes figures from Tables 1 and 2 and shows where profits during the 6-month period were used. The negative cash flow of 40,000 from our cash forecast is included as current assets column. This overdraft can be booked as advances from owners that need adjustments (as a current liability or additional equity). We have also added the net

Human Resource Management Assignment Example | Topics and Well Written Essays - 2500 words

Human Resource Management - Assignment Example Here was nirvana for organizational success- the magic formula one could replicate and make its own and hopefully rise to the top amid the competition. Thus the idea of high commitment HR theory and practice was born. We all know that quality is never an accident- it is almost always the result of painstaking and committed effort (Aquayo, 1991). We see this effort in Japan’s adoption of Edward Deming’s Total Quality Management principles, Motorola’s Six Sigma Manufacturing, Philip Crosby’s The Eternally Successful Organization and even Peter Senge’s The Learning Organization. Like any living creature with a body and soul, an organization too has strengths and weaknesses. The organization and its management must also continually learn from and adapt to changes in its internal and external environment, without which it would be hard to survive and prosper. This is what strategic management is all about. From a reading of the case, it is clear that the Container Store has been quite successful in creating and maintaining its niche market in the Storage and Organization retail segment of the home furnishing and house ware retail industry. From humble beginnings in 1978, the company managed to carve out and maintain an enviable position for itself as market leader in an expanding niche market. The Container Store management however realises that competition is fierce and to meet this challenge they have embarked on a high commitment HR strategy that treats the employee as a centre point for sales, work productivity and an attitude of service with a smile. As Vice President Sharon Tindell has observed, the company needs highly trained and committed people to sell its specialised products. Its niche is to sell the hard stuff. However, keeping staff motivated and satisfied is not without its challenges and as we shall see, the HR manager of the enterprise would be hard pressed to create a performance appraisal system that is adequate for its employees, yet equitable and justifiable so that it is appreciated by all. Mission and Guiding Principles of the Container Store As we can see, the foundations of success of the Container Store are very much ensconced in its mission and guiding principles. The mission of the Container Store is the words of its chairman Boone, ‘to better the lives of consumers by giving them more time and space.’ To this end, it has connected employee and customer satisfaction, for it believes that there is no better way to satisfy a customer than by putting him in contact with a highly satisfied, well trained and fully committed employee. The company is convinced that eminently satisfied employees display a service and work attitude that is enviable and that results in better sales, more customer satisfaction and a WOW experience every time. Furthermore, the hours of dedicated and specialised training that is invested in employees whether full time or part time also make one wan t to produce more sales and satisfaction for the company. In fact the company has consistently been rated as one of the best, if not the best, in customer service and employee satisfaction for a number of years running in the industry. The company has a stringent employee selection and recruitment process that consists of a telephonic interview, a group interview and

International Economic Growth Essay Example | Topics and Well Written Essays - 1250 words

International Economic Growth - Essay Example The reduction in costs facilitated trade between countries and the shipment of goods to other countries became easier and cheap. It also leads to exchange of services, technology, factors of production and economically useful knowledge. The fall in transportation cost was also accompanied by an increase in the transportation speed. With the combination of fast, cheap and easy transportation, inter-trade between countries grew. Labor became mobile due to introduction of fast ways of travel and migrated to different countries to take advantage of better job opportunities. Moreover, due to increased communication and exchange of technology, a change in lifestyle also occurred in many countries. The use of new technology was adopted by many countries so the lifestyle of people living in these countries became similar also leading to a global economy. To sum up, migration, international specialization, trade and public policies helped create a global economy before the First World War. The First World War took place mainly in Europe between the years 1914 and 1918. The aftermath of the war saw a huge impact on the economies of the countries that fought, (Britain, Italy, U.S, France, Germany, Greece, Japan, Portugal, Turkey and Russia among others) and ultimately, affected the global economy by bringing the process of global economic integration to a halt or at least slowing the process down. 2. 'The First World War represents a turning-point in the economic history of Europe.' Discuss. The First World War is certainly a turning point in the economy history of Europe as it steered the economy in European countries away from moving towards a globally integrated economy. Firstly, it was because world international trade suffered a sharp decline after the war as the United States, Great Britain and France still had some conflicts. The European economy suffered a great financial setback in the war and faced many economic difficulties. Many industries that were opened to support the war had to be closed down and the countries saw a rise in the level of unemployment. The rise in protectionist policies proved to be a barrier to free trade and adversely affected the growth of many countries' economies. Capital movements between countries became restricted and relations between countries weakened further. Also, there was a decline in the level of production and transfer of resources to the production of military goods had to be stopped. To help the country survive in the war, many countries had taken loans which in no way was favorable for their declining economy at that time. As predicted, the economies of many countries had to face an economic crisis. Wealthy people lost their money and there was a sharp fall in the living standards of people. The GDP (Gross Domestic Product) of these countries subsequently fell. In 1918, Britain imposed the system of rationing. However, issues of rising prices, worker's disputes regarding pay and overtime and lack of proper housing arose. It gave way to many strikes and unrest prevailed in European countries. The First World War was indeed a turning point for the economy in Europe as it did not support the great economic growth of the pre-Great war, disrupted lives,
