The City Of Phoenix Arizona Is Made Up Of Multiple Cities

Who moves to the middle of the desert and expects to survive? The Metropolitan of Phoenix Arizona is made up of multiple cities. Prior to the settlement of large populations of people there was multiple free flowing rivers that fed water to not only people but to the irrigation of crops as well. With the increase of the population of people and the decrease of rain fall in the Phoenix Metropolitan area there was a deficit of water resources available to sustain the metropolitan cities. In addition, because of the decreased absence of steady rain water fall annually there had to be safe guards put in place to combat against potential flash floods. Dams were constructed and channeled water away from the original flow patterns of the rivers and this created additional problems of habitat degradation. What was once a full and vibrant ecosystem had now suffered, leaving some native animals and species of plants without a sustainable habitat. These problems were addressed by city of ficials and the Tres Rios Full Scale Project was hatched. It’s my belief that the Tres Rios Water Treatment initiative has created a natural and Eco-friendly way to return cleaner waste water back to the water ways of three major rivers that sustain life here in the valley of the sun. This man made wetland if you will has renewed natural habitats and created an indigenous sanctuary for Phoenix native wildlife, providing a twofold process of further treating waste water through a natural processShow MoreRelatedBioterrorism Teaching Plan2820 Words   |  12 PagesCOMMUNITY ASSESSMENT AND ANALYSIS OF PHOENIX ALISHA HERMOSILLO EMMAH MAINA LISA GREENSPON PRIYA CANALES GRAND CANYON UNIVERSITY NRS-422V AUGUST 18, 2013 COMMUNITY ASSESSMENT AND ANALYSIS OF PHOENIX Community assessment and analysis by the community health nurse is of vital importance.

It has different kind of functions and used in household and restaurant. The operation method is very simple. Input Ac current from a wall socket and ingredients needed to mix a desire finish goods as output. To develop or re-design a new product that will be appealing to the consumers. This is challenges for any kind of product. We analysed this product used various tools such as value analysis. From analysis this report explained there are little room to improvement for design, manufacture and assembly. The many component of the product made from plastic and which is cheap as produce with economic of scale and recycle these parts easy. This report will explain about sustainability and how EU control the waste by the implementing low. Introduction: The main objective of the blinder is to mix different ingredients to form of a new product, e. g. banana shake involved with mixing banana and milk. This is not always easy to bland because of different out put required different speeds to create a good mix. Because of that a blander will provide several speed settings. For smooth, well mixed products, it becomes necessary that a blinder will able to spin at a Varity of speed. The speed can be varying with the desirable output. The redesign of the product can be produce with economics of scale with maintain of environmental issue. Weihrich Koontz (2005) explain that, create product ideas by examining consumers needs and screening the various alternatives, after the product is designed, prepare to lay out of the facilities to be used, plan the system of production, and schedule the various tasks that must be done. 2. 0 Current design: This type of blender can be made of glass, plastic, stainless steel or porcelain. Design is a problem solving activity (Lecture notes). Designer must be developing a product or service that meets a customer wants and needs through dissatisfaction. (Appendix 1). The demanded for the blinder is defined. The PDS shows that top of the container are a lid to prevent ingredients from escaping during operation. At the bottom is a blade assembly, sometimes removable for cleaning purposes. In cases where the blades are removable, the container should an o-ring between the body of the container and the base to seal the container and prevent the contents from leaking. The container rests upon a base that contains a motor for turning the blade assembly and has controls on its surface. Most current blenders offer a number of possible speeds. Low – powered blenders require some liquid to be added for the blender to operate correctly. High-powered blenders are capable of milling grains and crushing ice without such assistance. 2. 1 product description: Stand Blender XB9196G -5 Speeds with pulse -Capacity: 1. 5 L -Powerful 450 W motor -Stainless steel blade -Transplant glass Jug. -Voltage: 120V/230V -Wattage: 500/450 W 2. 2 Application: First, after remove the blender from the box and plug it in to a 120V wall socket. The consumer must then assemble it by placing the lid on the pitcher, the nozzle on the bottom, and attach the pitcher to the blade turner. Second, the pitcher can only fit in to the base one way because of the grooves and the markings. Third, the consumer would then fill the pitcher with whatever they would like to blend before adjusting the speed. There are three options: smooth, mix, and pulse. These basic descriptions for the speeds are clear and easy to understand. â€Å"Smooth† could be perceived as blending something thoroughly therefore it is the higher speed of the two locking buttons. Mix is slower and could be perceived as more stirring. Pulse can be used to intermittently blend the contents of the pitcher at a highest speed. Forth, trying to keep consumers hand on the top of the blender while pushing the buttons can lead to some difficulty. To pour, the consumer removes the top of the blender and grasps it by the handle or the grooves. To store the blender, unplug it and clean thoroughly. Fifth, to clean, the consumer takes apart the blender by removing the pitcher from the blade holder by twisting. This is usually kept tight so that liquid does not leak out the bottom therefore it is difficult to remove. Once the base is screwed off, the blades are easy to access. The nozzle must have water passed through to clean thoroughly but it is not intuitive how to screw the nozzle apart. 2. 3 Value analysis: (VA) Value is monetary terms of product and services relates with consumer desirability, worth and utility. ‘Value analysis is an organised programme to optimise the value of the product by eliminating unnecessary cost. (Lecture notes). The price for the final consumer can be reduced by the producing as bulk. The Fixed cost (FC) should set up as minimise level as possible and control on Variable cost (VC). When Marginal cost will be Zero, there will be possible to reduce the price than competitors. But the some of the specific components production cost is higher than other parts of the blender. The Pareto Principle (also known as the 80-20 rule) states that 80% of the effects come from 20% of the causes. 2. 4 Product life cycle: PLC goes through many phases, required skills, knowledge and many professional disciplines. As a product blander is a mature product as voice of the customer. But according to manufacturing it may not be mature product. Because of this product still required many components. There are four things to assert for PLC: 1. Product have a limited life. 2. Product sales pass through different stages and face different challenges. You read "Product Design" in category "Papers" 3. Profits rise and fall in different stages. . Product required combination of marketing, finance, manufacturing, purchasing, RD, HR in each life cycle stages. A blinder is in a perfect competition market. So manufacturer need to combine different marketing and production mechanism with efficiently and effectively. So, Boone and kartz (1990) explain four stages through which a succes sful product passes: introduction, growth, maturity, and decline. 2. 5 Manufacturing method and materials: The current product main four components: The motor, base, the pitcher and operational control. The pitcher made from glass. The component made from glass, plastic and stainless steel. 3. 0 Re-design: Redesign of the product transforms the quality better. So what is quality? Galloway ET (2000) explains that this represents the degree to which the design of the product or service meets the requirements of the market. Re-design of the blinder is not dramatic change. There are two major changes than previous model. The jar made by glass (previous) new model made from plastic. There are two main reasons, e. g. it is very cost effective as a material used and re-cycle is more environmental friendly. Another major change is touching Pad. There ware knob for the increase and decrease of the speed (old model). New model touch pad is implemented by numbers. Because of easy to operate in terms of level of speed required for specific output and usable friendly for all kind of consumer. (Appendix 2). This report will explain about different component of the blinder in re-assemble section. 3. 1 Value analysis: Value is interpreted in macro sense; it does not explain not only the cost of material but factor of other productions. The final product needs to face challenges of satisfactory. Does the product value with money? The utility of new jar can be appropriate with SMART analysis. Consumers can relay on this product as any condition of mixer. But glass jar is not friendly with hot condition of mixer. This product is Hazard Free to use, easy to maintenance and the life time depends on use. But it is completely disposal product. There is little sound pollution during operating time. 3. 2 Design for manufacturer: The current product is composed of 4 major components: the pitcher, motor, base, and operator control. The pitcher is made of plastic and is made by injection molding. The subparts of the pitcher are assembled with the use of fasteners. The parts of the pitcher are ease of assembly. There is a blade holder assembly at the base of the plastic pitcher. This piece is plastic and is used to attach the pitcher to the base of the blender. This blender blade fixture is also plastic. But it needs to be bored out with a drill through the middle forming an area for a long screw from the blade assembly. The production of the blades is from a slab of metal where slices of equivalent sizes are taken in order to produce mass amounts of blades at one time. The blender blade setup uses two identical blades 90 degrees to each other that sit on top of one another that are kept in place with simple washers and a long screw. The second major component is the motor which is inside the base and directly under the pitcher. The motor is produce from a specialized motor company. The problem of heat transfer must be examined. The heat produced from the motor will not melt the parts nearby. The motor is made to fit under the base and is sufficiently mounted. The mounting clips are under the blender base and are made to withstand the movement associated with the vibrations from the motor. The mounting clips are extensions on the base allowing for more strength. However, many parts of the motor attachment are attached by gluing which may result in problems with reusing or taking apart the glued components during the assembly process. The third main component is the base. It is made of plastic and is mass produced most likely by injection molding. The base is made durable enough to withstand added liquid in the pitcher as well as a running motor. The last component is the operator control that allows the user to choose different blending speeds. 3. Designs for Assembly: The blender actually consisted of over 50 components. Although we only mentioned the 4 main parts of the blender assembly, the actual manufacturing process was actually very difficult and time consuming due to the mass amount of components and attachments. The future design for the blender would most definitely need to reduce the amount of components to speed up the rate of the manufacturing process. 3. 4 Design for dis- assembly: This report will explain all component of a blinder. So readers can get the information in micro level of the operation. Pitcher: Pitcher made from plastic and it holds liquid and it injection moulding. Cover: Cover top of the pitcher made from plastic and has two parts of moulding. Handle parts: This is for the user to hold pitcher and made from plastic. Pitcher Nozzle: It’s manufacturing process injection moulding and dispenses liquid from pitcher. It is made from plastic. Plunger stick: It is converts force of nozzle into plunger and made from plastic. Plunger Rubber: The function of this part opens up passage for liquid flow and made from rubber. Round Knob: The function of this part directs plunger stick and made from plastic. Plunger washer: The manufacturing process of this part is stamped and function is distributes load over spring. This is made from aluminium. Spring: Spring loads the nozzle lever and made from steel. The manufacturing process is coiled. Nozzle Lever: This pat use for dispense liquid and made from plastic. Blade Subassembly: Upper blade: The main function of this part is cuts food and ice and made from steel. The manufacturing process is milling stamping bending. Lower blade: This part has similar function like upper part. It has same weight as well. Blade shift: The function of this part is transmit rotation of blade turner to blades and made from steel. Washer: The function of this part is distributes load evenly on blade and made from hard fiver. The manufacturing process is stamping. 3Flange Nut: It is attached blade holder to shift and made from steel. Blade Holder: The main function connects blade to pitcher and made from plastic. Bearing: This part made from brass and main function is allows blade to rotate in respect to holder. Blade holder O-ring: It main function is reduces liquid drip page and made from rubber and manufacturing process is injection moulding. Yellow clip ring: This part attaches pitcher to motor cover and made from plastic. White black ring on blade holder: It has similar function of blade holder o-ring. Blade turner: The main function is transmits rotation of motor shaft to blade shaft and made from steel or plastic. Motor sub- assembly: There are few parts e. g. damper, damper/blade washer, motor/damper washer, motor/damper bias, motor cover screw washer and another three main components e. g. Motor fan: The main function of this part is to reduces temperature of motor and maid from plastic. Upper and lower motor bracket: This part made from either plastic or aluminium or copper. The function is holding the motor in place. Motor Assembly: The function is the magnetic field run generates an magnetic field on the motor. This part made from plastic. User interface subassembly: Base and motor cover: Both are made from plastic. One function covers the top of the motor and another cover the bottom of the motor. The other parts of the components are motor cover screws, base screws, button, spring, bottom bracket, signal transmitter. 3. 5 Design for sustainability: Sustainable design is also called ‘Green design, ‘eco design’. It is art of designing physical objectives, the build environment comply with the economic, social and ecological sustainability. Most of the parts of blander are non-toxic and almost all components are recyclable and required little energy to process. The product has powerful 450 W motor which required 120V which require less energy. This is more household and restaurant useable product so it lasting longer. The most of the materials can be use in commercial new production afterlife. The processing of e-waste is causes serious health and pollution problems. The technology change, low initial costs have the fasted growing problem around the world. In the 1990 some of the European countries banned the disposal the electronic waste in lands fields. All unwanted electronic goods can return to sales points with free of charge. This is the producer responsibility for dispose. The EU implemented a system in 2003, under the waste Electrical and electronic Equipment Directive (WEEE 2002/96/EC). The directives transform in national low. The producer should collect their goods from customer and dispose it ecologically friendly manner. 4. 0 Conclusion: Re-design of the blinder is more cost effective and can be produce by economic of scale. It needs to satisfy the consumer demand and needs to face competition in the market. It had been redesign cost effectively and use environmentally friendly. The all components can be reusable for produce of the other new product. The production organisation has more CSR in terms of disposal. As finished goods it needs to face different stages of life. It can be redesign with the time goes and market mechanism change. There are more RD required for this product in terms of assembly and noise pollution.

Texas Concealed Weapons Proposal

Table of Contents Introduction Bill Summary The Pros and Cons of the Legislation Conclusion Works Cited Introduction As of 12 March, 2010, about 48 states in the United States permitted non-law enforcement individuals to carry concealed weapons such as handguns in public. However, no such legal provisions are allowed in Illinois, Wisconsin, and Washington, DC except for active and retired police officers.Advertising We will write a custom essay sample on Texas Concealed Weapons specifically for you for only $16.05 $11/page Learn More Accordingly, those supporting the state concealed carry legislations (CCW) argue that the likelihood of a criminal attacking an armed person is very minimal. On the other hand, the opponents of these laws argue that allowing non-law enforcement persons to carry concealed guns would lead to increased gun crimes and inadvertent gun injuries in public places (Austin par. 3). However, beside the high-profile shootings in Vir ginia Tech, University of Texas, and Northern Illinois University, different reports show that in the year 2008, there were not less than 5000 assaults, 3000 sexual assaults, and 4500 robberies in different college campus across the United States (Austin par. 7). As a result, the Texas House of Representatives introduced a legislation, which allows carrying of concealed weapons in college premises. The bill, which was introduced by Rep. Joe Driver, seeks to give residents of Texas who are licensed to carry guns as stipulated under certain state legislations similar rights to self-defense within college campuses (Austin par. 2). Therefore, this essay provides a review of the contents of the bill, and an explanation of the pros and cons of the bill as provided by various expert groups and individuals. Bill Summary According to the CCW legislation, a license holder is allowed to carry a concealed firearm in any institution of higher education in Texas. Moreover, the institution is not allowed to adopt any regulations, provisions or rules seeking to prohibit the license holder from carrying the weapon to college. However, in relation to subsection (e), an institution of higher education in Texas is allowed to adopt regulations regarding the storage of firearms in college premises. In addition, the institution may adopt regulations after consultations with students and faculty members to prohibit license holders from carrying their guns in restricted premises within the institution. Besides, the legislation does not provide for license holders to carry their guns into hospitals run by the institution for higher education (Wentworth et al. 1-6). The Pros and Cons of the Legislation Proponents of the CCW legislation give various reasons as to why they support the enactment of the law. For instance, David Burnett, the president and spokesperson of the group, Students for Concealed Carry, argues that CCW comprises of fully established laws in Texas, which provide for t he right to self-defense for license holders. Besides, the process of establishing eligible persons for the CCW involves considerable deliberations on one’s age, psychological and mental status, training, and other background checks (Burnett par. 6).Advertising Looking for essay on government? Let's see if we can help you! Get your first paper with 15% OFF Learn More Moreover, the legislation states clearly that only license holders and legally-armed individuals are allowed to carry weapons in colleges. Furthermore, historical events show that ‘Gun-free Zones’ do not deter criminals from committing crime, and thus, concealed weapons would allow individuals in such zones to protect themselves and others from hostile criminals. Additionally, studies show that over 26 colleges are currently allowing firearms in college premises without any unprecedented problems (Burnett par. 11). Therefore, the legislation does not increase the risk of gun crimes but it can help in providing the much-deserved protection in campuses. On the other hand, opponents of the legislation argue that providing untrained or undertrained individuals with guns will pose increased risk to these individuals and their colleagues due to unintentional accidents (Burnett par. 3). Furthermore, public opinion shows that the larger population is against the presence of guns in places like sports grounds, banks, hospitals, and campuses. Here, the opponents of the state concealed carry legislations (CCW) argue that there is the paramount need to stop the violence epidemic associated with over 30,000 deaths and 70,000 injuries annually. In addition, the CCW procedures have several rope holes, which have led to availability of too many weapons in too many public areas (Burnett par. 7). As a result, there is the need to limit access to guns in order to minimize crime and accidents in public places. Conclusion From the foregoing discussions, we note that the state conceale d carry legislation (CCW) has many benefits as well as shortcomings, which are worth the attention of the authorities responsible. However, the fact that most colleges are unable to provide sufficient protection to all students cannot be overstated. Moreover, claims that colleges are much safer than most cities and urban establishments do not hold considering that currently, cases of crime, sexual assaults, and killings are on the rise in most institutions for higher education in the US. As a result, if these institutions have failed in providing security to students and faculty members, then there is no need to deprive them of their right to self-defense. Therefore, there will be a net positive impact in most colleges in Texas upon enactment of the legislation. Works Cited Austin, Mark. Texas leads nation with campus carry bill.

That's because atoms are mostly made up of empty space between very tiny, very dense nuclei. If you're intrigued by the mind-blowing facts and figures of physics, you might be considering the SAT Physics Subject Test. This comprehensive guide will go over exactly what's on the test (don't worry, nothing about sugar cubes). It will also tell you where you can find the best SAT Physics practice tests, and the study tips and strategies you need to know to master the SAT II. There's a lot that we cover in this guide, so here's a table of contents so you can easily find the specific information you're looking for. Format of Physics Subject Test Types of Questions on Physics Subject Test Concepts Tested on Physics Subject Test Where to Find Practice Tests How to Study for the Physics Subject Test Test-Taking Tips When to Take the Physics Subject Test How Is the Physics Subject Test Formatted? The SAT II in Physics is 60 minutes long and asks 75 multiple-choice questions. Every question has five answer choices. There are some independent questions, while others are grouped and ask about the same graph or picture. Perhaps surprisingly, you can't use a calculator on the Physics Subject Test. With less than a minute for each question, the test doesn't present overly complicated math. There are three main types of questions, which are important to understand so you can know which skills to apply. Types of Questions on the Physics Subject Test The three types of physics questions are recall, single concept, and multiple concept problems. Recall questions make up 20% to 33% of the test. They are somewhat straightforward and test your understanding of the concepts of physics. This is an example of a recall question: Answer: E Single concept problems make up 40% to 53% of the test. In addition to recalling a concept, you have to apply a physical relationship, formula, or equation to solve a problem. These questions test your understanding of simple algebraic, trigonometric, and graphical relationships, along with concepts of ratios and proportions. Answer: E Multiple concept problems account for 20% to 33% of the questions. They have the extra step of asking you to recall and bring together two or more different relationships, formulas, or equations in order to solve a problem. Answer: A Now that we understand the format of the test, let's break down the content on the test even further so you know what to study for the test. As you'll see below, it focuses primarily on mechanics and electricity/magnetism. What Is Tested on the Physics Subject Test? According to College Board, the SAT II in Physics covers mechanics, electricity and magnetism, waves and optics, heat and thermodynamics, modern physics, and other miscellaneous concepts. Mechanics and electricity/magnetism questions make up over half the test. Let's look at how the test breaks down. Mechanics: 36% - 42% Kinematics, such as velocity, acceleration, motion in one dimension, and motion of projectiles Dynamics, such as force, Newton's laws, statics, and friction Energy and momentum, such as potential and kinetic energy, work, power, impulse, and conservation laws Circular motion, such as uniform circular motion and centripetal force Simple harmonic motion, such as mass on a spring and the pendulum Gravity, such as the law of gravitation, orbits, and Kepler's laws Electricity and Magnetism: 18% - 24% Electric fields, forces, and potentials, such as Coulomb's law, induced charge, field and potential of groups of point charges, and charged particles in electric fields Capacitance, such as parallel-plate capacitors and time-varying behavior in charging / discharging Circuit elements and DC circuits, such as resistors, light bulbs, series and parallel networks, Ohm's Law, and Joule's Law Magnetism, such as permanent magnets, fields caused by currents, particles in magnetic fields, Faraday's Law, and Lenz's Law Waves and Optics: 15% - 19% General wave properties, such as wave speed, frequency, wavelength, superposition, standing wave diffraction, and Doppler effect Reflection and refraction, such as Snell's Law and changes in wavelength and speed Ray optics, such as image formation using pinholes, mirrors, and lenses Physical optics, such as single-slit diffraction, double-slit interference, polarization, and color Heat and Thermodynamics: 6% - % Thermal properties, such as temperature, heat transfer, specific and latent heats, and thermal expansion Laws of thermodynamics, such as first and second laws, internal energy, entropy, and heat engine efficiency Modern Physics: 6% - % Quantum phenomena, such as photons and photoelectric effect Atomic, such as the Rutherford and Bohr models, atomic energy levels, and atomic spectra Nuclear and particle physics, such as radioactivity, nuclear reactions, and fundamental particles Relativity, such as time dilation, length contraction, and mass-energy equivalence Miscellaneous: 4% - 9% General, such as history of physics and general questions that overlap several major topics Analytical skills, such as graphical analysis, measurement, and math skills Contemporary physics, such as astrophysics, superconductivity, and chaos theory In addition to these concepts, you have to memorize certain formulas that express physical relationships, like F = ma. You have to be able to manipulate equations, read a graph, understand the metric system, and apply lab skills to answer questions. Is there anything you don't need to know? While this test is very comprehensive, there are a few things you don't have to worry about. You don't have to know trigonometric identities, calculus, three-dimensional vectors and graphs, or physical constants. The Physics Subject Test covers a great deal of content, and requires your ability to apply those concepts to manipulate equations and solve problems. Besides learning and studying in your physics class, what materials can you use to prep for the Subject Test? Where to FindSAT Physics Practice Tests You can prepare for the Physics test with high-quality practice questions in books and/or online. First,our book recommendations: Books Using official practice questions is always the best way to prepare for the SAT or SAT Subject Test. College Board currently only provides Physics practice questions in its All Subject Tests Study Guide. While the questions are high quality, because they come from a previously administered test, there is actually only one practice test to try out. Obviously, this is very limited, so you'll want to supplement with another book. You might try studying first with other books and then taking the College Board practice questions a week or two before the Subject Test to make sure you're ready. Because it's a previously administered test, it will be a good benchmark to predict how you'll score, and it can reveal any concepts you need to study last minute before test day. For a comprehensive overview of the concepts you need to know and high-quality practice questions to apply them, I recommend Princeton Review's Cracking the SAT Physics Subject Test. You can use this book throughout the year in physics class to review the concepts and make sure you can apply them to SAT Subject Test questions. One downside of Princeton Review is that the explanations can sometimes be confusing and difficult to follow. Barron's is also a good option with high-quality practice questions. However, some concepts are lacking, so don't rely on it to be completely comprehensive. Barron's would be best to use two to three months in advance of your Subject Test, after you've been reviewing in class and with Princeton Review throughout the school year. Finally, two other options are Kaplan and McGraw Hill, but they would be my last recommendation. Kaplan questions are too easy, so they won't be sufficient preparation. McGraw Hill questions have the opposite problem - some are way too complicated to solve without a calculator, and thus not accurate preparation for the SAT Subject Test. Besides books, you can also find SAT Physics questions online from these sources. Online Practice Questions You should definitely give College Board's 36 online practice questions a try. Make sure to thoroughly read the explanations of any questions you're unsure about or don't know. Then review the concepts, from your class or other test prep materials, and take notes and do practice problems to shore up your understanding. Varsity Tutors has a bunch of helpful practice questions broken up into subsets of concepts. These are a good way to really identify what you know and what you need to review. This similar site also has helpful practice questions that you can automatically score, along with some glossaries and study guides. Finally, Sparknotes, though it doesn't have practice questions, has an informative overview and glossary of terms. How to Prep Effectively for the Physics Subject Test Now you have a bunch of good resources for the Physics Subject Test, but how can you use them effectively to maximize your scores? This section goes over three key study tips to follow. #1: Use Class Material The Physics Subject Test is a challenging test. It covers a lot of material, and this material takes a significant amount of time to learn. Thus staying focused and up to speed in class is vital, as well as reviewing the concepts and practice problems frequently to retain your cumulative knowledge. As you go through your physics class, you should review your classwork in conjunction with a test prep book like Princeton Review or Barron's. Then you can really do more intensive test prep in the two to three months before the Subject Test. Make sure to do a practice test a couple weeks before the test to get a good sense of your preparation and fill in any last minute gaps in knowledge. While you're taking these practice tests, you should make sure to time yourself. #2: Time Yourself Physicist John Wheeler Archibald explained, "Time is what prevents everything from happening at once." With the Physics Subject Test, you might feel like everything is happening all at once because you don't have much time at all. Timing yourself while you take practice tests will help you with pacing and time management. As you strengthen your ability to answer questions quickly and efficiently, you'll both score higher and breathe easier that you have enough time to get to all the questions and answer them well. When you take a full-length practice test, give yourself exactly 60 minutes and sit in a quiet room with few distractions. The more you practice under simulated testing conditions, the more prepared you'll be on test day. Once you take the test, you want to score your questions actively and critically. #3: Analyze Your Answers Correcting your practice tests should be a very active process. By this I mean don't simply let a wrong answer or lucky guess go. Wrong or skipped answers are an opportunity to really analyze the questions, diagnose your weaknesses and misunderstandings, and figure out where you need more prep. If you get a question wrong, mark it down in a notebook. Figure out why it was wrong- did you not know the concept, misunderstand the question, or make a careless error? If the first, you should definitely go back in your notes and review. Then find practice questions that test those concepts. So much of the Physics Subject Test is about application, not just recall. If you didn't understand the question or made a careless error, you probably need to focus on your time management and ability to focus and work efficiently. Practicing under timed conditions, as mentioned above, is the best way to train this skill. Practice tests will reveal where your strengths and weaknesses lie. Each question is an opportunity to pinpoint what you know and what you need to study further. Remember important formulas, like this one. Test-Taking Strategies for the Physics Subject Test Besides getting ready through test prep, there are some strategies you should keep in mind while taking the Physics Subject Test that should help you boost your scores. #1: Know Your Formulas You can't bring a formula sheet with you when you take the Physics Subject Test. The test will give you some constants, but you have to know the formulas that express physical relationships. Note that you also can't bring a calculator into the test. While it might seem like there are a lot of formulas to remember, they will probably start to seem intuitive the more you understand the laws and concepts of physics. If there are any that you have a hard time remembering, it might be a good idea to jot these formulas down in your test booklet at the beginning of the test. This way you can refer back to them as you go along. Make sure you know your formulas as you're studying, as well as how to apply them to single concept and multi-concept problems. #2: Use Process of Elimination On the Physics Subject test, you lose 1/4 of a point for every question you answer incorrectly. If you can't eliminate any answer choices, you should leave the question blank and avoid a point deduction, but if you can eliminate at least one wrong answer, then you're better off making your best guess. Go through the answer choices and see which ones you can cross off as definitely incorrect. This may also jog your thinking in how to approach the correct answer. #3: Don't Dwell With 75 questions in 60 minutes, you have less than a minute to spend on each question. If one of them leaves you stumped, it's best to mark it, skip it, and return to it at the end of the exam if you have time. Remember, it's always a good idea to guess if you can eliminate at least one of the answer choices. But don't spend a disproportionate amount of time on a problem, as all problems count equally toward your ultimate score. #4: Read Critically Sure, this is the Physics SAT, not a critical reading test, but the same skills of close and critical reading apply. Make sure you understand exactly what the question is asking before rushing to answer it, and be on the lookout for words like EXCEPT, BUT, ALWAYS, NEVER, or any other superlatives or words that mark a shift in emphasis. The more you practice, the more calmly you'll be able to approach the questions and deploy these strategies. When Should You Take the SAT Physics Subject Test? You can take the Physics Subject test on the May, June, August, October, November, or December test dates. College Board recommends that you have at least one year of college prep Physics before taking the Subject Test, as well as courses in algebra and trigonometry and experience in the lab. The end of junior year is a common time to take the Physics test, but some students might feel prepared at the end of sophomore year. Either way, it's best to take the test at the end of the academic year when the course content is fresh in your mind. You might also be studying for a final, which will further reinforce your understanding. Remember, you can't take an SAT Subject Test on the same day as the SAT, but you can take up to three Subject Tests in one day. It might be smart to take the SAT first, so that your math studying can inform your physics prep. With these considerations in mind, the June test date would be an ideal time to take the Physics Subject Test. You can read about other considerations for scheduling your SAT Subject Tests and the full list of dates here. With your study plan and test schedule all planned out, you will be well prepared to show off your physics skills on the SAT Subject Test and add this impressive exam to your college applications.

Research proposal - Essay Example In this research proposal, therefore, attentive oral hygiene is a significant part of VAP prevention approach; though there is a difference in the real practice for particular application technique, products utilized, and timing prevent development of VAP. The participants will be ICU adults receiving mechanical ventilation who are in need of regular oral care hygiene. The problem is that there are no definite recommendations in the guidelines about a specific solution to be utilized and the frequency of oral care. A research in an ICU suggest that performing oral care thrice a day with routine tooth brushing minimized the rate of pathogenic bacteria colonization in the oral cavity that resulted in a remarkable reduction in the prevalence of VAP (Ebbing, 2010). In recent studies, use of 2% chlorhexidine solution as the oral care hygiene technique in ventilated patients indicated a lower rate in oropharyngeal colonization with gram-negative bacilli and therefore, a reduction in the de velopment of VAP (Ebbing, 2010). The research topic is ‘what is the most efficient intervention to reduce ventilator associated pneumonia in adult ICU patients; use of antiseptic agent (chlorhexidine) or performing oral care (using toothbrushes or toothpaste)?’ The tooth brushing technique will involve the use of a soft toothbrush to clean the patient’s teeth to reduce plaque. Also, the patient’s gums and tongue will be brushed to stimulate the tissues (Urden, 2014). The use of antiseptic agent chlorhexidine will be performed after a duration of 6 hours, which is a recommendation for patients undergoing mechanical ventilation. In such a case, the patient’s teeth should be cleaned before using chlorhexidine to minimize staining. However, chlorhexidine can be made less active by toothpaste if used within a period of thirty minutes to two hours. Where the two methods may be

Papper about photographer - Research Paper Example They cumulative effects of Araki’s images are great. Araki establishes the notion that everything strictly Japanese, by design, prohibits outsiders from participation. Japan has been, in the western perception, the very replica of the other even though it remains vague to what level this repeal is true (Sharp 23). Araki’s art should, in reality, fall in this group of the other for people now that the photographer hardly ever leaves Japan, that he did not go to a western university and that he strictly speaks Japanese (Searle 1). However, his works attain exactly the opposite effect. Westerners gain the adamant feeling that these images are addressed to them - not in the logic that they are reflections of western traditions or images - like the travesties of western cinema and art found in the parodies of the Japanese picture taker Morimura - but because they function in line with the rules established in western â€Å"modernist† discourse. This paper will dwell o n this photographer and give a brief biography of his life, as well as his works. Biography Nobuyoshi Araki was born on 25th May, 1940, in Tokyo, Japan. He studied cinematography in his college days and, after graduating, went to work at Dentsu, a Tokyo-based advertising company, where he met essayist Yoko Araki, who become his future wife. Araki was only 32 years when he quit his job at the advertising agency and, after that, his works remained nearly unrecognized in the Western world (Design Autopsy 1). Of the over 70 brochures and books that published his images, produced in Japan those days, none of them were available in America and even Europe. His initial solo show outside Japan was in 1992, in Graz, and then subsequently started appearing in Germany, Austria, Holland, Switzerland, Scandinavia and Scotland. This was from 1992 to 199 (Design Autopsy 1). The years were considered a success story for the photographer who was barely known outside his nation. However, he was not t he normal artist, who is introverted, painstaking or regional, unfairly neglected by the chaotic exhibition scene (Design Autopsy 1). Araki had long before become a star in Japan’s media and a person always bounded by an entourage just like the king of pop, Michael Jackson. Araki was a tough person, a classy maverick and an artist acknowledged for particular eroticisms albeit for extremely different images. Having transformed through the countless rumors and the astounding tales connected to his name, an observer is attracted to such comparisons(Searle 1)As hard as it is to imagine Araki the artist and the photographer, the objective of tracing the genesis of his ads and deciding the actual objective is not less elusive (Design Autopsy 1). Araki’s images are full of explicit sexual characters and also heavy sexual metaphors. However, the explicitness in Araki’s photos is not â€Å"hot† as the way as it is exhibited in the sex industry (Sharp 45). His meta phors also forge connections to many other, likewise corporeal images - interiors and cityscapes, which are normally devoid of individuals and have a figurative passion of their own (Searle 1). Araki draws from a vast store of pictures, which are extended endlessly – images that have neither titles nor dates – and eventually circles around a diminutive core of normally recurring
