25 to 32 Fast ACT Prep Study Plan in 10 Days

25 to 32 Fast ACT Prep Study Plan in 10 Days SAT / ACT Prep Online Guides and Tips Do you need to raise your ACT score, ASAP? Do you want to make a huge score improvement, from good to amazing- from 25 to 32? It’s not easy, but you can take huge strides toward the ACT score of your dream in just 10 days.In this article, we show you how to pinpoint your weaknesses, create an effective study plan, and significantly raise your ACT score. Who Should Use This ACT Study Plan? Because this is only a 10-day plan, you'll have to commit to between two and five hours each day to see major improvements. Unfortunately, there's no substitute for putting in ample prep time, whether that’s an hour a day over five weeks, or a more concentrated plan like this one. If you do have more time before your test date, we highly recommend spending at least five weeks studying for the ACT. It’s easier to guarantee a score boost of 25 to 32 if you give yourself more time to practice. But if you want to improve your score quickly, or have already taken the ACT and want to improve your score before college apps are due, keep reading. This plan integrates a key component of all good study plans: focusing on your weaknesses. When time is of the essence, you need to make every hour count. How well you can do this will ultimately dictate how much you improve on the ACT. Now, let's take a look at the three steps you'll need to take to get your 10-day study plan started. Step 1: Take a Practice Test Your first step is to take an official, full-length ACT practice test. Even if you’ve taken the ACT before, you need to find out exactly what your strengths and weaknesses are before you begin studying. Remember to simulate actual test-taking conditions, including using a bubble sheet, and to follow official timing restrictions exactly. After you’ve taken the test, calculate your score out of 36 for each section to get your composite score (i.e., your total ACT score) and subscores. You can read our guide to learn more abouthow ACT scoring works. As you go over your answers, note where you lost the most points. For example, maybe your geometry subscore was super low but your other math subscores were good. Or maybe you lost points randomly, meaning you'll have to dig a little deeper to figure out which concepts you're struggling with. The ultimate goal is to pinpoint your weaknesses so that you can study the most effectively. Reviewing your mistakes is essential to formulating a solid prep plan. Your 10-day plan could look very different based on how you do on the practice test. Let's use three hypothetical students as examples: Student A, Student B, and Student C. Student A'sPractice Test Scores English: 23 Math: 25 Reading: 26 Science: 25 Composite: 25 Student A has work to do across the board to get her composite score up to 32. Although we'd recommend this student definitely devote some serious time to studying ACT grammar rules to raise her English score (her lowest section score), every single section score must see significant improvement for her to hit her goal score of 32. Student B's Practice Test Scores English: 30 Math: 24 Reading: 24 Science: 26 Composite: 26 Student B should spend the majority of the 10 days practicing Math, Reading, and Science. They can improve their English score by 2 points (up to a 32) by simply scoring 2 or 3 more raw points on that section- which shouldn’t require hours of extra studying. However, they'll need much bigger raw point gains for the other sections. Don't worry, Student B. By following this 10-day study plan, you'll be able to meet your ACT score goals! (Valerie (Vee) Bordeleau/Flickr) Student C's Practice Test Scores English: 30 Math: 20 Reading: 32 Science: 22 Composite: 26 Student C needs to make serious gains in Math and Sciencebut is already strong in English and Reading. He should focus his 10-day program on figuring out his content weaknesses in Math and Science, addressing them, and then drilling practice questions. He can also spend some time working to improve his English and Reading scores so as to lessen the burden on his presumed Math and Science score increases. Any additional composite point he can gain on English or Reading is one he doesn't have to earn on Math or Science. For example, he could aim for 34 on both English and Reading and 30 on both Math and Science and still get a composite score of 32. Step 2: Set Raw Score Goals for Each Section For this guide, we are assuming an ACT goal of a 32 composite score. But how many raw points (i.e., the number of questions you answer correctly) do you need to aim for to get this score? Here are the number of questions you'll need to get correct on each section: English: 70 out of 75 Math: 54 out of 60 Reading: 38 out of 40 Science: 38 out of 40 We added an extra raw point to these target scores compared with the ACT scoring charts, since the scaling can change slightly from test to test. If you can achieve all these raw scores, you will most likely get a 32 composite score. Remember, the ACT composite score is averaged, so you could get two 30s and two 34s and average out to 32 for all sections. You can use our scoring guide to set your own raw score goals if you have different section goals or a different composite score goal in mind. Note that at this level, you should be answering every question. Don’t just do 70 English problems and leave the rest blank. Answer every question with the goal of getting them all correct, so that if you do have some wrong answers, you can still get a total of 70 raw points. Want to improve your ACT score by 4 points?

This way you get the most out of your study time and make the most improvements in the least time possible. You won't have to worry aboutwhatto study - just focus on learning. Check out our 5-day free trial: Step 3: Gather ACT Prep Materials The final step is to gather the ACT study materials you want to use throughout your study plan. For step-by-step guidance, we highly recommend our PrepScholar ACT program.We go through the process of identifying your weaknesses for you, giving you more time to focus on filling in content gaps and improving your score. If you’re going at it alone or just want more tools, though, here's what we recommend for your ACT prep: #1: ACT Prep Books Use our guide to the best ACT prep books on the market as a starting point for building your ACT prep book arsenal. These prep books contain practice problems, tests, and the content information you'll need to fix your weaknesses and get a 32 on the ACT. Definitely start by getting The Official ACT Prep Guide and the Black Book, plus subject-specific books if your performance on your practice test shows weaknesses in certain areas. For example, we'd recommend Student C from our example above get books specifically for Math and Science. #2: Test Accessories Pencils, erasers, a calculator, a watch- think of these as tools you need to do well on the ACT. It might seem trivial, but getting used to using a (ACT-approved) watch to time yourself can help you save time on the test. Plus, if you aren't used to telling time on a watch (as opposed to a cell phone), it's better that you get used to doing so before a high-stress situation like a standardized test. The same goes for your calculator: you want to make sure you're familiar with the calculator you'll be using on the ACT so you don't waste valuable time on test day fiddling around with it. Using non-mechanical pencils and erasers instead of pens on the test will get you into the right mindset for the test as well. If you're doing the ACT Essay, writing with a non-mechanical pencil is even more important because you need to get used to writing in pencil for long stretches rather than just for bubbling in answer choices. #3: Our Free Online ACT Resources We've got a lot of free ACT prep resources to offer you at PrepScholar. Our free eBookgives you a more in-depth guide to improving your ACT score and identifying and fixing your weaknesses. We also strongly recommend readingour article onhow to get a perfect 36 on the ACT, written by our resident perfect scorer; this guide will help put you in the right mindset for a 32 or higher. Even if you're not trying to get a 36, you'll need to use these principles to improve your ACT score, especially in such a short time frame. Finally, we've consolidated all of our writing on the ACT sections into ultimate prep guides. Whether you want general tips or specific strategies, these guides have them all. Learn the principles and get the tools you need to propel your composite score to a 32 with our complete study guides to ACT English, ACT Math, ACT Reading, and ACT Science. If you plan to take the ACT with Writing, be sure to also check out our ultimate guide to theACT Essay. #4: Free and Official ACT Practice Tests Sitting down and taking realistic, full-length ACT practice tests is key to preparing for the ACT. Not only will it familiarize you with the test format, but it'll also help you pinpoint your weaknesses and work on them, as well as give you an idea of how your studying is going. Use our collection of free and official ACT practice teststo get started. General Advice as You Begin Studying for the ACT Before we go over our 10-day plan, here are some of our best tips for getting the most out of your ACT prep. Follow these to help you get the biggest score improvements in the least amount of time. #1: Always Guess There's no guessing penalty on the ACT, so even if you’re at the end of a section and have two questions left you can’t answer, it's best to just fill in random answers. You have a 20-25% chance of getting a question right, so take the shot! #2: Use the Process of Elimination Eliminating wrong answers is a good way to approach tough questions, and will increase your odds of getting points if you encounter a question you're not sure about and end up guessing on. Even though the right answer isn’t always obvious, it’s usually easy to spot at least one or two wrong answers,raising your odds of getting a question right to 33% or even 50%. #3: Don’t Get Stuck on Hard Questions A great strategy is to mark difficult questions and come back to them later. Timing is key on the ACT as you have less than a minute per question. This means thatif you waste five minutes on a hard question, you are losing the opportunity to work on five more questions, which can seriously tank your score. Seeour guide on ACT lengthfor more tips on pacing yourself. #4: Mark Questions You're Unsure About When practicing, don’t just correct multiple-choice questions and tally your score. Rather,star any questions you weren't sure about. That way, when you correct your answers, you can make sure to study that type of question and see why you struggled with it (even if you got it right). If you only focus on wrong answers, you could actually leave some content gaps unfilled. Remember, the goal isn't to study until you can get most of the answers right- it's to study until you're confident that you won't get any questions wrong. #5: Identify and Fix Weaknesses When correcting your answers to ACT practice questions, don't go over the answer explanations too quickly. You need to figure out why you got an answer wrong as well as how you can keep yourself from making this mistake again. Just drilling practice questions without understanding your true weaknesses won’t help you improve your score. We suggest taking notes on your mistakes in a notebook. This will help you keep track of your content weaknesses and guide your studying. #6: Don't Sweat the Essay The ACT Writing section, or Essay, does not affect your composite score.So if getting 32 is your main goal, don’t spend tons of time practicing for the Essay. You only have 10 days, and you'll need to use them wisely! While we recommend preparing for the Essay to an extent (I suggest reading our guide to writing the ACT Essay), don't waste precious hours practicing for this section when you still have big point improvements to make on other, more important sections. 10-Day ACT Study Plan Now that we've gotten the basics out of the way, here is a 10-day ACT prep plan you can use to go from 25 to 32. Again, be aware that this a very time-intensive plan.To truly benefit from it, you'll need to clear your schedule as much as you can and give yourself adequate time to study. Days 1-4: Fill In Content Gaps Time: 3-4 hours per day As you start studying, your first priority is to pinpoint topics you don’t know and learn them. You can’t expect to get 32 with major content weaknesses. Whether you struggle with interpreting scientific studies, solving plane geometry questions, or remembering grammar rules, your first step is to find out what you don’t know and then master it. Use your results from the practice test to determine what to focus on during these first four days. You should then use your prep program, books, and/or other study materials to concentrate on subject areas you're struggling with the most. On each day, focus on a single ACT section: English, Reading, Math, or Science. Take practice sections and use practice questions, but don’t worry about taking full practice exams just yet. For example, Student A above would devote one day each to all of the sections, whereas Student C should probably spend two days on Math and two days on Science. Suggested Time Breakdown 1-2 hours: Find weaknesses in the section. Use your prep books and online resources to fill in your content gaps. After you’ve learned the new content, quiz yourself on each individual weakness. For example, if you realized you always miss subject/verb agreement questions on the English section, first read up on subject/verb agreement and then do practice problems that quiz this topic specifically. 35 minutes-1 hour: Take a full section from a practice test, strictly timed. If pacing is an issue for you, experiment with doing a combination of untimed sections, time-and-a-half sections, and officially timed sections. 1 hour: Review mistakes from the practice test and make sure you understand them. Remember to take notes on your mistakes in your journal! Research additional content weaknesses if needed. Days 5-7: Take and Review Practice Tests Time: 4-5 hours per day During this time you'lltake a full practice test each day (excluding the Essay section at the end). Even if you have strong sections, like Student C above, do the practice anyway so you can identify any silly mistakes you tend to make and can ensure you'll do just as well on test day as you do in your practice. Consistency is key! As you test, star questions you're unsure of to make sure you revisit them while correcting, even if you end up getting them right. Spend time afterwardidentifying your mistakes and figuring out why you made them. Don’t just brush off an answer and say, â€Å"Oh, I forgot the Pythagorean theorem, so I guessed." Figure out why you couldn’t remember the formula and thenmake a plan so you can get similar questions right in the future. Also, revisit questions you starred even if you ultimately got them right. It's important to address any stubborn content gaps. Suggested Time Breakdown 3 hours: Take a full ACT practice test (ideally, an official one) without the Essay section. 1-2 hours: Correct your test and carefully note all of your mistakes in your notebook. Figure out where your remaining weaknesses are and research any content gaps you still have. Days 8-9: Review and Target Weaknesses Time: 3-5 hours per day Based on your performance on the practice tests, you'll now do more fine-tuned work on areas you still have weaknesses in. Here are some examples of what you could focus on in your prep: Drill areas you're still making mistakesor have content weaknesses in. Maybe you’re struggling with the trigonometry questions on Math. In this case, head back to your study materials to review the content before you do any more practice questions in that area. Do more practice sections if you'rerunning out of time or struggling with pacing. Remember to wear a watch and keep an eye on how much time you spend on each question. If you're consistently hitting 32, continue to take full practice tests and grade them. Your goal is consistency, so keep practicing, even if you think you're set to go. Spend some time working on the Essay. Again, the Essay does not affect your total ACT score, but you don’t want it to be extremely low in comparison. Check out our guide to writing an ACT essay to help you get started. Day 10: Brush Up On Weaknesses and Rest Time: 1-2 hours You don’t want to study too intensively the day before the test- this will burn you out and do more harm than good! At this stage, it's best to do some practice problems in your weak spots, or one or two practice sections if you're working on pacing, to keep your mind warmed up. That said, remember to focus on relaxing and getting rest before the test, too.Read our tips for getting ready the night before and the morning of the test. Additionally,make sure you don’t forget anything important when you go to take the test! What’s Next? If you’re not sure you can handle this on your own, check out PrepScholar’s ACT study program.

Units of Analysis as Related to Sociology

Units of Analysis as Related to Sociology Units of analysis are the objects of study within a research project. In sociology, the most common units of analysis are individuals, groups, social interactions, organizations and institutions, and social and cultural artifacts. In many cases, a research project can require multiple units of analysis. Overview Identifying your units of analysis is an important part of the research process. Once you have identified a research question, you will have to select your units of analysis as part of the process of deciding on a research method and how you will operationalize that method. Lets review the most common units of analysis and why a researcher might choose to study them. Individuals Individuals are the most common units of analysis within sociological research. This is the case because the core problem of sociology is understanding the relationships between individuals and society, so we routinely turn to studies composed of individual people in order to refine our understanding of the ties that bind individuals together into a society. Taken together, information about individuals and their personal experiences can reveal patterns and trends that are common to a society or particular groups within it, and can provide insight into social problems and their solutions. For example, researchers at the University of California-San Francisco found through interviews with individual women who have had abortions that the vast majority of women do not ever regret the choice to terminate the pregnancy. Their findings prove that a common right-wing argument against access to abortionthat women will suffer undue emotional distress and regret if they have an abortionis base d on myth rather than fact. Groups Sociologists are keenly interested in social ties and relationships, which means that they often study groups of people, be they large or small. Groups can be anything from romantic couples to families, to people who fall into particular racial or gender categories, to friend groups, to whole generations of people (think Millennials and all the attention they get from social scientists). By studying groups sociologists can reveal how social structure and forces affect whole categories of people on the basis of race, class, or gender, for example. Sociologists have done this in pursuit of understanding a wide range of social phenomena and problems, like for example this study that proved that living in a racist place leads to Black people having worse health outcomes than white people; or this study that examined the gender gap across different nations to find out which are better or worse at advancing and protecting the rights of women and girls. Organizations Organizations differ from groups in that they are considered more formal and, well, organized ways of collecting people together around specific goals and norms. Organizations take many forms, including corporations, religious congregations and whole systems like the Catholic Church, judicial systems, police departments, and social movements, for example. Social scientists who study organizations might be interested in, for example, how corporations like Apple, Amazon, and Walmart impact various aspects of social and economic life, like how we shop and what we shop for, and what work conditions have become normal and/or problematic within the U.S. labor market. Sociologists who study organizations might also be interested in comparing different examples of similar organizations to reveal the nuanced ways in which they operate, and the values and norms that shape those operations. Cultural Artifacts Sociologists know that we can learn a lot about our society and ourselves by studying the things that we create, which is why many of us cultural artifacts. Cultural artifacts are all the things that are created by humans, including the built environment, furniture, technological devices, clothing, art and music, advertising and languagethe list is truly endless. Sociologists who study cultural artifacts might be interested in understanding what a new trend in clothing, art, or music reveals about the contemporary values and norms of the society that produces it and those who consume it, or they might be interested in understanding how advertising might impact norms and behavior, especially in terms of gender and sexuality, which has long been fertile ground for social science research. Social Interactions Social interactions also take a wide variety of forms and can include anything from making eye contact with strangers in public, purchasing items in a store, conversations, engaging in activities together, to formalized interactions like weddings and divorces, hearings, or court cases. Sociologists who study social interactions might be interested in understanding how larger social structures and forces shape how we behave and interact on a daily basis, or how they shape traditions like Black Friday shopping or weddings. They might also be interested in understanding how social order is maintained. Research has shown that this is done in part by intentionally ignoring each other in crowded public spaces.

Address an economic issue of current interest to WSJ readers Assignment

Address an economic issue of current interest to WSJ readers - Assignment Example This is a considerable drop, when compared the previous year’s estimate of 12%. This has also caused new home building to slow down which directly affects economic growth. Besides, the effect of this drop to the economy, those planning to buy new homes may have a smile as the pressure on home prices is expected to ease up with a notable drop of 1.2% compared to the same period in 2013. After reading the article, I would like to share few ideas that crossed my mind concerning what the editor states about economic growth and the real reasons behind this drop. For a start, I believe there are various reasons that are responsible for this drop and severe weather and rising mortgage is only a fraction of these reasons. As it is a trend, new homes only account for 10% of all home sales; therefore, a drop in sales for home sales does not necessarily mean that homebuyers have slowed down. This means that, despite the severe weather conditions and rising mortgage, new home sales could have gone down after losing potential buyers to older house sales. An article in 2013 by Cho highlighted that Shadow Inventory held by the GSEs and US-HUD largely outnumbered REO. This shows there is a large supply of homes that could come to market and sustain the current demand, leaving little room for new homes. In support of this opinion, another article by Gundlach specifies that the hou sing market is soft and has been significantly slowed down by the aging pool of loans in the foreclosure process. The forecast done by National Association for Business Economics on this year’s housing investment is a valid reason that, despite the severe weather conditions, new home ownership will still experience slow growth perhaps, the rise in mortgage being a more viable reason. Other significant factor in the drop, in new home ownership, is the increasing cost of

BP is also considered to be among the largest producers of global natural gas producers. Of note is that the production of natural gas by BP plc currently makes up for more than half of the company’s energy production. It is this aspect that has caused the company to become the largest natural gas suppliers and producers in the United States (British Petroleum, 2013). There are a number of BP plc external environment factors that can be able to greatly affect the success of the company. These include factors such as Economic factors and social factors. Economic factors such as interest rates, inflation, economic growth, exchange rates and taxation changes can greatly affect the overall success of BP plc. High interest rates might potentially deter the company from investing in certain regions across the world because it generally costs more to borrow, factors such as inflation might result in the provocation of high wage demands by the company’s employees which will then result in increased cost of production, having a strong currency may potentially cause it to become more difficult for the company to export its produce as it might raise the price in terms of foreign currency. Social factors can also affect the success of BP. Changes in social trends can impact the demand of the company’s products as well as the willingness and availability of individuals to work for the company as employees (Abrams, 2013). Factors such as an increasing aging population can also force BP plc to recruit older employees whose rate of production might be relatively low. BP plc has a number of key stake holders that are found to be crucial in the company’s operations, some of these stake holders include the company employees, its shareholder and analysts as well as various governments and regulators.

Historical Survey of Dental Restorative Materials

Historical Survey of Dental Restorative Materials Historical Survey of Dental Restorative Materials Introduction: Dental restorative material is a biomaterial used to restore the shape and function of damaged or missing tooth (caused by caries or trauma). Restorative materials can be divided into two types depending on whether they are designated to be applied directly to the injured tooth or fabricated in the lab firstly. 1. Direct Dental Restoration: Direct restoration means the usage of dental materials to save injured tooths function. A filling is a way to restore a damaged tooth by decay to recover its function and shape again (1). There are several kinds of materials which are used as filling. The right choice is determined by many factors; such as: extent of required repair, cost, having allergies to specific materials, etc Metallic Fillings: Gold fillings: gold has used as filling material. It is prepared in a laboratory and after that it is cemented into required place. Gold inlays are well compatible by gum tissues. Gold is considered the best filling material because it may last more than twenty years (1). However, gold filling often requires many visits to dentist as well as it is the most expensive choice. The following figure is for tooth with gold filling: Fig. (1): Gold filling Amalgam Fillings: first introduction of amalgam was in the United States in 1830, then this material was developed in both England and France. The amalgam fillings consist of silver, copper, zinc, tin and mercury. After starting of using amalgam as filling, controversy arose because of adding the mercury to fillings. At the beginning, this material is not embraced in the USA by the organized dentistry. In 1840, many members of dental surgeons of the American Society refused to use amalgam as filling material(2). In fact, the amount of mercury which was added to fillings was harmful to the health of patients. The mercury exists in filling may seep into the patients system and lead to a number of health concerns, for example: cancers or multiple sclerosis. Therefore, nowadays a lots of precautions have been taken to be sure that amalgam fillings are safe as possible as for patients (3). Generally, amalgam fillings are resistant to wear and inexpensive. But, according to their dark color, they are not desirable like other filling materials as well as they are not used in visible areas, like front teeth. The following figure is for tooth with amalgam filling: Fig. (2):Amalgam filling Non-metallic Fillings: Resin-Based Composite (RBC) fillings: composite fillings are closely to be the same color of natural teeth and these fillings are used where a natural appearance is required. The components are mixed and then placed directly into the tooth cavity, after that they harden. Actually, many experiences have approved that composites are not the ideal filling for large cavities because they may wear over time. As well, composites may become stained from tobacco or drinks like coffee or tea. They do not last more than three to ten years, however, recent research has suggested that the longevity of resin-based composites could be equally to amalgam (4). The following figure is for tooth with composite filling: Fig. (3):Composite filling Porcelain fillings: these fillings could be inlays or onlays. They are produced to order in a dental laboratory and then bonded to the damaged tooth. Porcelain fillings can be resist staining and matched to the natural tooth color. Generally, porcelain restorations cover most of the tooth. However, the cost of these fillings is similar to gold fillings. Glass-ionomer cements/water-based cements: Self-setting which is pure glass ionomers, or light cured which is resin modified glass-ionomers. Glass ionomer restoratives become popular with dentists because of their adhesive properties as well their ease of handling. They are relatively poor in resistance to moisture. These fillings have adequate compressive strength to be used as core build-up. However, flexural strength and fracture toughness of these materials are low. Therefore glass ionomer cements are suitable to place where there is tooth substance remaining to support the filling material and where resistance could be obtained from tooth tissue. Cermet cements do not supply advantages more than glass ionomers and they usually have poor adhesion to tooth structure(5). In general, the longevity of glass-ionomers is lower than that of amalgam or RBCs (4). Long-term temporary fillings; for example: reinforced zinc oxide-eugenol cements (4). 2. Indirect Dental Restoration: Indirect restorations are prepared in laboratory away from the injured tooth. Indirect restorations include inlays which are intracoronal, crowns and bridges that are extracoronal, or onlays which is considered as a combination of intracoronal- extracoronal. Crowns: Crowns could cover all/ partially the surfaces of tooth. After making a decision which restoration should be done for patient, materials and methods should be determined to begin the fabrication (5). Design and Materials Selection for Indirect Restorations: Gold: For more than 4 thousand years, gold has used as a restorative material in dentistry. The first gold fixed bridges were introduced by Romans and then its dental applications have published widely (6). The selection of restoration type and design will depend on the clinical situation details. However, gold is considered as one of the most efficient restorative material especially as extracoronal. Fig 4,5 show Cast gold crown (7,8). Fig (4): Cast gold crown Fig (5): Cast gold crown Advantages Disadvantages Having a hardness which is similar to the normal enamel Gold crown is fabricated by cast process from molten that may sometimes lead to microgaps at margins which are liable to decay Contours of occlusal and axial are built up clearly in the wax Visibly different from the color of natural teeth long-lasting High sensitivity hot/cold Used for complete/partial tooth coverage. long procedures for preparation (cast) and treatment Avoiding problems caused by using dissimilar metals High cost Porcelain: For many years, porcelain has used as a dental restorative material. Porcelain is a brittle material that requires special treatment for surface, such as: etching and silanisation. Porcelain crowns require restriction to anterior teeth excluding some types such as, Empress II, Inceram and Procera which are considered high-strength ceramics. Advantages Disadvantages Strong hardness of porcelain is more than natural enamel, that may cause damaging to the other natural teeth (for example; clench and grind) Natural looking Small thickness makes porcelain brittle and fracture No conductivity of (heat-cold) More reduction of tooth structure should be done Suitable for metal sensitivity-patients Fig 6 shows porcelain crowns (8). Fig (6): porcelain crowns Porcelain metal: Porcelain metal crowns combine between durability strength of the metal, and good aesthetics of the porcelain, Fig.(7): shows porcelain gold crown (8). Fig (7): Porcelain Gold Crown Advantages Disadvantages Comparing with full porcelain it is Stronger more durable Opacity because of the metal base Better aesthetic than full metal Existence of dark metal edge at the gum line Bonding techniques used are less sensitive than techniques used for full porcelain Porcelain and metal base could separate during use Limitation because of metal allergies of some Patients Composites: Recently, Composites are used widely in dentistry according to their high strength, high wear resistance and less expensive than other materials like: porcelain, gold, or zirconia. As well, composites used in onlay/crowns have permanent form stability comparing with other materials (5). However, sometimes a material less wear-resistant is more favorable to be sacrificial to nature. Fig. (8) shows a composite crown (5): Fig (8):A composite crown Table (1) illustrates comparison of materials used for indirect restoration (9): table (1): Comparison of materials used for crown manufacturing Porcelain Porcelain metal Gold alloys Metal alloys Biocompatibility Well tolerated. some patients may show allergenic sensitivity to base metals.

Resistant Sensitivity Low thermal conductivity High thermal conductivity Implants: First introduction of dental implants was in the 1960s by Brà ¥nemark. Dental implants are fabricated to replace missing teeth. The chemical and physical properties (composition characteristics of the implant surface and its microstructure, in addition to the design of implant) determine the factors which influence the implant therapy. Many criteria should be achieved such as, strength, biocompatibility, toughness, resistance of wear, corrosion, and fracture. The design principles and the physical properties of the material must be compatible. Table 2 includes materials used to produce dental implants due to their chemical composition (10). Table (2): Chemical composition of implant material Titanium Titanium Alloys: Several metals and metallic alloys including: gold, cobalt chromium, and stainless steel are used to produce dental implants. Last research declare that titanium is the gold standard metal to fabricate dental implants.

This alloy is made up of 6% aluminum 4% vanadium (Ti-6Al-4V) (10). Reports indicate that incidence ranging of titanium implant fracture from 0% to 6%,on the other hand, it is an uncommon occurrence. Fig (9): shows the titanium implant fracture. Fig (9): Titanium implant fracture. Recently, there are some concerns that titanium could evoke an undesirable host reaction; however, little evidence is available about that. Ceramics First introduction of ceramics to dental implants were in the form of coatings onto metal-based implants. They were used to improve osseointegration. Recently, various forms of ceramic coatings have been used for dental implants. Table 4 illustrates ceramic materials used as dental implants (10): Table 4: Ceramic materials used as dental implants Material Chemical Composition Hydroxylapatite (HA) Ca10(PO4)6(OH)2 Tricalcium phosphate (TCP) ÃŽÂ ±, ÃŽÂ ²,Ca3(PO4)2 Fluorapatite (FA) Ca10(PO4)6F2 Tetracalcium phosphate Ca4P2O9 Calcium pyrophosphate Ca4P2O7 Brushite CaHPO4, CaHPO4 ·2H2O Bioglasses SiO2-CaO-Na2O-P205-MgO, Aluminium oxide Al2O3 Zirconium oxide ZrO2 Zirconia is the most favorable among oxide ceramics according to its excellent mechanical properties. Yttria stabilised tetragonal zirconia polycrystalline (Y-TZP) materials exhibits high corrosion wear resistance, in addition to its high flexural strength (800 to 1000 MPa) comparing with other dental ceramics (10). An understanding of the bio-mechanical failure modes of zirconia implants is essential so that an optimal zirconia implant design can be developed. Based on more fundamental studies in the biomaterials science field, the physical mechanism of ceramic implant failure can be either chemical and/or mechanical in nature. Mechanical failure can occur either during the surgical placement of the implant or subsequent functional loading. Clinical examples of fracture modes of zirconia implants are shown in fig. 10,11: Fig (10): zirconia implant fractured during surgery Fig (11): zirconia implant fractured after loading.

Business Law I Chapter 9 Answers Essay

1. Consideration consists of mutual exchange of gains and losses between contracting parties. In the exchange, a gain by the offer is at the same time a loss to the offeror. The legal term used to designate the gain that each party experiences is that party’s legal benefit. Consideration has three characteristics 1) The agreement must involve a bargained-for exchange; 2)the contract must involve adequate consideration; and 3) the benefits and detriments promised must themselves be legal. 2. A legal detriment can be any of the following: 1) doing something that one has a legal right not to do; 2) giving up something that one has a legal right to keep; and 3) regaining from doing something that one has a legal right to do. 3. The law will not enforce an agreement that has not been bargained for. An agreement involves a bargained-for exchange when 1) a promise is made in exchange for another promise, 2) a promise is made in exchange for an act, or 3) a promise is made for forbear ance of an act. 4. A court may refuse to enforce a contract or any clause of a contract if is considers the contract or clause unconscionable, that is, the consideration is so ridiculously inadequate that it shocks the court’s conscience. This designation usually happens when there is a great inequality in bargaining power between the two parties. 5. Consideration can be a promise not to sue. A promise not to sue, when there is right, or at least the apparent right, to sue, is enforceable when it is supported by consideration. Promising not to sue is forbearance. Acceptance of an agreement not to sue, supported by consideration, terminates one’s right to continue any lawsuit, presently or on the future, on grounds described in the agreement. 6. There are three ways that the courts can seek to uphold charitable pledges. The first way involves actual consideration, which occurs when charitable contributions are made on the condition that the promisor be remembered for the gift by having his or her name inscribed in some way on a memorial associated with the project. Another approach is to use either promissory estoppel or public policy to support the claim. Also, when there is no promise to carry out a specific project, the courts have held each pledge made is supported by the pledges of all others who have made similar pledges. This concept of consideration is used in support of all promises of money for undefined causes. 7. If a creditor accepts as full payment an  amount that is less than the amount due, the dispute has been settled by an accord and satisfaction. Accord is the implied or expressed acceptance of less than what has been billed the debtor. Satisfaction is the agreed-to settlement contained in the accord. Only if the dispute is honest, and the offer to settle made in good faith, and not superficial or trivial will the courts entertain arguments based on accord and satisfaction. 8. The agreements that be enforceable by a court of law even though they lack consideration are: a) Promises under seal – enforceable in some states for contracts not involving goods Unenforceable under UCC for contracts involving goods. b) Promises after discharge in bankruptcy – enforceable in most states. c) Promise to pay debts barred by statute of limitation – enforceable. d) Promises enforced by promissory estoppel – enforceable only if offeror knew that offeree would rely on the promise and offeree places himself in a different and difficult position as a result of that promise. e) Option – enforceable under UCC if made by a merchant, in writing, stating the time period over which the offer will remain. 9. Promissory estoppel is a legal doctrine that restricts a party from denying that a promise was made under certain conditions, even though consideration has not been exchanged to bind an agreement. To be effective, promissory estoppel requires that the party making the promise know, or be presumed to know, that the other party might otherwise make a definite and decided change of position in contemplation of those promises. In reaching this doctrine, courts have accepted the principles of justice and fairness in protecting the party receiving the promise from otherwise unrecoverable loses. 10. Shopping online is one of the fastest growing market places on record. Despite its many advantages (quick & efficient, comparison shopping, availability of hard-to-get products) , there are many difficulties: – Cyber-payment option: Wide variety of methods. One of the most popular methods is by credit/debit card. Most online sellers will accept the major credit cards such as Visa, Master Card. This type of system protects both the buyer and the seller. This process may become the most acceptable process because most of the times when people buy and sell in  cyberspace they are dealing with strangers. The online payment process eliminates the identity verification problem. This is important because one of the biggest concerns about online shopping is security. – Cyber-Payment Security Issues: the ease and efficiency of using credit/debit cards is frequently offset by the security concerns associated with their use. The US is not up-to-date as the EU in providing data and privacy protection to its consumers. The EU Data Protection Directive along with EU E-Privacy Directive guarantee the rights of European citizens while at the same time ensuring the smooth exchange of data among those nation-states that honor the privacy and data protection standards themselves. US corporations that are involved with EU corporations must demonstrate that, despite the lack of legislation in the US, the companies themselves will promise to honor the same degree of protection to data and to privacy as guaranteed by the EU. These guarantees have been labeled the Safe Harbor Principles. They are enforced by the US Department of Commerce. It is best for a consumer to check directly with the US Department of Commerce to determine the true status of a company rather than just relying on the company’s blanket assertion that they follow the safe harbor standards.
