Chemistry Vacuum Pump: Enhance Different Applications

Chemistry Vacuum Pump: Enhance Different ApplicationsThe chemistry vacuum pump is used for both light and heavy-duty applications. The right use of this type of pump can be advantageous for a variety of applications such as extracting fine liquids, vacuuming, cleaning chemical-filled drums, explosives disposal, and extraction of toxic materials. The system can also be used in the extraction of sedimentary rock and coal, or for combustion.The pump is made up of a number of components which will depend on the materials needs. Some of the main components are the reservoir, the condenser, the flow valve, the core, and the motor. The pump must have all of these components, because it is used to extract and to supply fluid to different parts of the body. Depending on the size of the pump and the body, the other parts of the pump will need to be the same.The reservoir, commonly called the tank, contains the solvent. It is the container in which the fluid is circulated, but it does not hold the fluid in itself. It is filled with the solvent, usually an aqueous solvent, in a separate container. This is a single container which holds the fluid but does not contain the fluid.The condenser is the process which regulates the pressure in the system. It is where the heat energy in the solvent is converted into heat. It has the opposite function of the reservoir in that it cools the hot solvent.The flow valve is the one that controls the flow of the fluid through the pump. It takes the form of a lever and is located at the bottom of the pump. When the lever is turned clockwise, the pump moves the flow of fluid to the end of the tube. When the lever is turned counterclockwise, the flow goes to the beginning of the tube. The flow is controlled by the movement of the lever.Tchemistry vacuum pump The motor in the pump is what actually drives the pump. It is the generator of the pump and gives it the power needed to move the fluid. It is a self-contained machine and its size depen ds on the motor. It usually contains a computer and sometimes an analog processor. Other types of motors include multi-phase, helical, and spiral. The speed of the motor also depends on the flow rate.In science research work, the chemical vacuum pump is often used for a variety of applications such as extracting liquids from materials and blowing materials out of the body. They can also be used to produce small quantities of gas, generate electricity, and even heat up water in the kitchen.

Whats Up with Donald Trump

Whats Up with Donald Trump Ive been avoiding writing something on Donald Trump for a long time, even though students, friends and co-workers from outside the U.S. keep asking me if this is for real. Does this guy really have a chance? A few have thought that Trump was actually some sort of bizarre joke.I havent written anything about it yet in part because I havent known exactly how to explain the Trump phenomenon. Also,  Trump gets a ridiculous amount of attention already, and I hate  to add to it. But the video Im using this week is just too funny to ignore.Whether or not you like him as the next president (just to be honest, I dont) you have to admit that hes been a master of attracting free media attention. His campaign has done next to no advertising, yet hes easily the best known candidate for the 2016 elections.Youve probably heard some his more controversial statements. Hes proposed banning all muslims from entering the United States, hes proposed somehow making all 11 million undocumented immigrants l eave, hes insulted women, and a disabled reporter.So why do people still like him? Why is he doing well in the polls? The video below makes an hilarious attempt at answering this question. Watch the video, then see if you can complete the listening exercise in comments.Vocabulary: A couple words to help you out.GOP Another name for the Republican Party, the political party for which Trump wants to be nominated.Focus Group A demographically diverse group of people that  participate in a guided discussion about a political campaign, product, television series, etc.Single Out  To choose a person or group of people from a larger group for special attention.Answer the questions below in comments, and well respond.What is the big question?Why does the report ask, Thats a good thing?What does he mean when he says, Just so were on the same page.Do you want a president in there that really ____ __  ______.What does the sentence above mean?What do you think of the vast majority conversati on?Why is the statement, Hes not singling out this group because of their religous beliefs so strange and funny?At last we had reached _____ ____.

9 Big Advantages of Learning a Foreign Language

9 Big Advantages of Learning a Foreign Language 9 Advantages of Learning a Foreign Language (+ Resources!) We live in a hyper-connected, fast-paced world, and things arent changing anytime soon.How can you keep your head above water?You need to be hyper-awesome to survive.That means youll have to  develop some special advantages to get a boost, help yourself stand out and make you better fit for survival in this crazy, modern world.As our world becomes more and  more connected through technological advances, its becoming increasingly obvious that learning another language is beneficial for many reasons.Here we present just a few of the many positive side effects of becoming bilingual (or multilingual). 9 Advantages of Learning a Foreign Language (+ Resources!)1. Meet new peopleOne of the most phenomenal benefits of learning a new language? Doors are opened to you  around  the world. If you’re learning in a group setting, you immediately have new friends to share your new language with. If not, then once you go somewhere and are actually able to employ what youve learned, you’ll be s urprised how open people are when you speak their mother tongue.2. Employers love it (and theyll love you more)If your C.V. accolades include fluency in a second language, your chances of employment in today’s economy are much greater for you than for those who speak only one language.Multilingual people are able to communicate and interact within multiple communities. Potential employers consider this a valuable asset in an employee’s skill set, as theyre able to connect with a broader range of people. In this new age of start-ups, companies are increasingly breaking into new markets. You up your personal and professional value if you’re able to negotiate with manufacturers in another country or communicate with customers who don’t speak your native language.Not to mention, your ability to speak a second language conveys that youre motivated and driven to learn new skills, and this also gives you a competitive edge over those who havent yet become bilingual.3. It’s becomi ng essentialMany would argue that bilingualism is becoming a progressively necessary and essential skill for anyone who wants to keep up with today’s rapidly increasing global economy. As more and more people recognize the importance of learning an additional language, those who only speak one language will begin to get left behind in our shift towards a more integrated and connected global society.4. It’s great for travelingAustrian philosopher Ludwig Wittgenstein is credited with saying that “the limits of your language are the limits of your world,” and he was right.Knowing more than one language opens up your vacation destination possibilities. Traveling through a foreign country becomes much easier if you can speak the language of that country. Fluency isnt required. Locals anywhere appreciate that youve taken the time to at least attempt to learn and communicate in their tongue. It shows a greater level of respect and is an easy way to meet new people.Also, getting to a comfortable speaking level in a foreign language is a great motivator to get you out there and practicing your new language in a new country.Not ready to rush off to a foreign land just yet? Not a problem. You can start exploring the everyday cultures of the countries where your target language is spoken with FluentU right now. FluentU takes real-world videosâ€"like movie trailers, music videos and inspiring talksâ€"and turns them into personalized language lessons.5. After learning one, it’s 1000x easier to learn anotherAs you begin to learn a second language, youll find that the acquisition techniques you’re using can be applied to learning additional languages as well.The positive cognitive effects of learning to speak a second language can train the brain to analyze and process different linguistic structures. Its not specific to your first target language its a skill that can be applied to learning any language.Youre increasing your ability to replicate the process with multiple languages. This is called metalinguistic awareness, where your brain learns to identify  the techniques of learning a language and break them  down into a series of steps. After learning one language, you retain the muscle memory. Your brain will intrinsically understand how to learn a language and how different languages are structured, through increased awareness of syntax, grammar and sentence structure.6. You become smarterAcquiring a second language improves your memory and increases your attention span. The process of becoming bilingual exercises your brain, challenges you to concentrate and boosts your problem solving skills.Bilingual students tend to score higher on standardized tests than monolingual students, especially in the areas of vocabulary, reading and math. As you learn to toggle from one language to another, you improve  your multitasking abilities. Bilingual individuals have also been shown to be more logical and rational, have better decision-making ski lls and be more perceptive and aware of their surroundings.Learning a second language also improves your native language, as it teaches you the mechanics and structure behind any  language not just new  languages.7. Youll stay smarter for longerRecent research has shown that bilingualism can stave off the effects of Alzheimers  and dementia by  years.  Regardless of their education level, gender or occupation, bilingual subjects in the linked study experienced the onset of Alzheimers, on average, 4 1/2 years later than monolingual subjects did.Study results out of the American Academy of Neurology are showing that speaking more than one language increases the amount of neural pathways in the brain, allowing information to be processed through a greater variety of channels. Theyve also begun to demonstrate that multilingualism improves development in the brain’s areas of executive function and attention, no matter what age the language learner is.8.  It boosts your creativityResea rchers are also concluding that multilingual speakers are more creative than monolingual speakers. Learning a foreign language improves not only your ability to solve problems and to think more logically, it also makes you experiment with new words and phrases.Leveling up your second language skills forces you to reach for alternate words when you can’t quite remember the original one you wanted to use. It improves  your skills in divergent thinking, which is the ability to identify multiple solutions to a single problem.9. It builds up your self-confidenceYoure about to teach yourself to believe, yes, I can. Itll become your new personal mantra.Confidence increases when a new skill is mastered, and learning a foreign language is no different. It increases your self-confidence. And let’s face it: confident people are more interesting than those who are unsure of themselves. The techniques you use to develop a second tongue result in a greater sense of open-mindedness.In order to master a new language, conversations with native and fluent speakers are essential. If you’re shy but want to meet new people, using the excuse that you want to practice your speaking skills is a great opener and a doorway to making new friends, expanding your horizons and broadening your life experiences. Plus, who doesn’t want to be more interesting?So, How Do I Get Started?Fortunately, gone are the days where the only way to learn a second language was to either become stranded in a foreign country or go back to high school language  classes (and be honest, did you actually learn all that much in there?) There are now many different online lessons and tutorials to help you become proficient in the language of your choice.FluentU  stands out amongst language learning websites thanks to the huge range of interactive learning opportunities it provides.FluentU makes it possible to learn languages  from music videos, commercials, news and inspiring talks.  Its all stuff that nati ve speakers  actually watch.  With FluentU, you learn real languagesâ€"the same way that natives  speak them.

5 Creative Summer Reading Tips

5 Creative Summer Reading Tips 5 Creative Summer Reading Tips As you bask in the summer sun and enjoy the longer days, it’s the perfect time to incorporate reading into your children’s daily routine. The magical thing about books is that they can make our imaginations soar by whisking us off to faraway lands or transporting us back into history, but they can also spark new interests. Ongoing research indicates that most students can lose up to two to three months of critical reading skills over the summer months. Whether at home, by the pool, on a plane, or at the local library, daily reading can strengthen your children’s reading skills. With a little creativity, summer reading can be fun and help prevent your children from spiraling down the “summer slide.” Here are five creative summer reading tips: Create a reading spot. Designate a cozy nook for your children where they can relax and get lost in a book. Try a hammock in the backyard or build your own reading fort with blankets and pillows. Connect books to travel or activities. With family trips and activities planned for the summer, find books related to where you’re visiting! If you’re planning a day at an aquarium, check out books related to various sea life. Or, if you’re visiting sites that are rich in history like the nation’s capital, dive into some books to learn about the country’s founding fathers. They will have fun connecting their own experiences to the books they are reading. Read the same books as your children. Tackling the same reading list as your children will be your own form of a book club! Engaging in thoughtful discussions will further develop their insight and critical reading skills. Visit your local library. Beat the summer heat and head over to your local library. Have your young reader explore the library and check out a book of their choice. Some libraries even offer story hours, educational speakers, workshops, and musical performances that will keep your children engaged! Subscribe to educational magazines. Magazines can be fun for children to read over breakfast and in between books!

Anaheim Math Tutor Tips Solve Fractions With a Simple Calculator

Anaheim Math Tutor Tips Solve Fractions With a Simple Calculator Anaheim Math Tutoring: Solve Fractions Even with the Simplest Calculator! Anaheim Math Tutoring: Solve Fractions Even with the Simplest Calculator! Even if you don’t have access to a graphing or scientific calculator, you can still check fractions with a much simpler calculator.   This can be relevant if you are using your phone, taking a test where your teacher supplies only simple calculators, or taking an online standardized test like the GRE where you only have an onscreen simple calculator. Many students do not realize it is still possible to work with fractions with these types of calculators.   It’s true that fractions likely won’t be nearly as easy to use on these options, and there is a good chance you will have to do some calculations by hand.   However, they are still a valuable tool to check your answers and solve some fraction problems.   First, let’s show some examples of simple calculators and then work through examples of how to use fractions with them (book your in-home Anaheim math tutor today). A Casio brand of a simple calculator with little extra functionality outside of addition, subtraction, multiplication, and division but with extra finance related options. A Karuida brand calculator similar to the Casio that is also very common. An example of a simple phone calculator.   Many phones may also have more calculator options on their stock apps (as well as the ability to download different calculator applications with more functionality), but this is an example of the few options that may be readily present. This is an example of an onscreen calculator that you may get for a computer-based test.   Specifically, this is the current calculator available on the GRE Here is a keychain or pocket calculator with no functionality outside of basic operations. We can now practice some examples of how to work with fractions using these types of calculators.   First, the most important fact to know is that the division function is how we can get access to fractions.   A division sign is the same basic function as a fraction bar â€" that is, to get   3/5 you would need to type 3 ÷ 5.   It is important, however, to do as few calculations at once on simple calculators.   Many will follow the order of operations, but others will just give you an immediate output from your first operation.   For example, to find     47-19/4   you would want to perform the 47 â€" 19 first and separately, then divide that answer by 4. Example 1: Here, we can input each of the fractions into the calculator first to get the outputs in decimal form.   We put into the calculator the first fraction as 4 ÷ 8.   The output we get is 0.5.   Next, we input the second fraction as 12 ÷ 8 and receive the output of 1.5.   Now we have converted both fractions into decimals and can add them as 0.5 + 1.5 to get the correct answer of 2. Example 2: Now, let’s try the same strategy as example 1.   We input the first fraction as 9 ÷ 4.   The output we receive on our simple calculator is 2.25.   We then input the next fraction as 1 ÷ 6 to get 0.16667 or some similar number.   We can now type these into the calculator as 2.25 â€" 0.166667 to get an answer of 2.08333.   However, this likely isn’t the answer we want, since it isn’t a fraction or full number. Unfortunately, there is no easy way around this problem without at least some knowledge of fraction manipulation.   The first option is to find a common denominator and subtract.   A quick way to do this is to multiple each fraction on the top and bottom by the denominator (bottom) of the other fraction.   So, we multiply the first fraction by 6/6   and the second fraction by   4/4.   This will change our fractions now to 54/24 4/24 .   Now we have a common denominator and can just subtract the numerators of each (54 â€" 4) to get a final answer of   50/24.   Finally, we can reduce this by dividing the top and bottom by 2 to get 25/12. Now we can get to the calculator part.   Input 25 ÷ 12 into a calculator and you get this result:   2.08333.   Notice that this is the same answer as when we worked with strictly decimals.   However, the decimal version took a lot few steps and was quick to find.   By doing this, we can essentially check our answers to make sure they are correct.   Complete the fraction operation by hand and find your answer as a fraction.   Then, convert it to a decimal in the calculator and find the decimal using just the calculator and compare answers.   If they aren’t the same, you likely made a mistake in your fraction operations. Example 3: With this example, let’s try to solve it just in the calculator.   We input the first fraction as 3 ÷ 25 to get 0.12 and the second fraction as 64 ÷ 500 to get 0.128.   Now we can add those two together: 0.12 + 0128 to get a final decimal of 0.248. In the last example, we were stuck with the decimal and could only use it to check our answer.   Here, however, we can notice that the decimal “terminates” quickly, or it stops after just a few digits.   Using this, we can write any terminating decimal as a fraction based on the furthest decimal place it has.   0.5 we could write as 5/10.   0.14 we could write as 14/100.   And 0.027 we could write as 27/1000.   Following this trend, we could write 0.248 as 248/1000.   This is a fraction that we can then reduce to have the simplest answer:   31/125 after dividing the top and bottom by 8. So, we can use even the simplest of calculators to solve fraction problems.   At best, you may need zero knowledge of how to solve fractions (example 1), and at worst, you will have to solve the problem normally but be able to check your answer (example 2).  There is also a good chance you will only need minimal fraction reducing knowledge (example 3).   Regardless of the situation, you should know how to use calculators to check your answers and solve problems â€" even when you don’t have a fancy calculator available.

What is the CLEP Exam and How can it Benefit my Child

What is the CLEP Exam and How can it Benefit my Child What is the CLEP Exam and How can it Benefit my Child? What is the CLEP Exam and How can it Benefit my Child? The CLEP exam, also known as the College Level Examination Program, is a series of tests that can help students earn college credit for general education courses if they receive a passing score. This can be a great advantage to students who know a significant amount of information about certain subjects, those who would like to save money on college, and those who are returning to school after a period of absence. The primary benefit is that if the student passes the test they are generally excused from the same course material in college. However, students are encouraged to find out from the university directly if they will accept the credits. 1. Amount of Credits According to the College Board, students who pass the CLEP exams should expect to earn anywhere from 3 to 12 college credits. This is a huge benefit to students who cannot afford to spend four years in college or those who feel they will become bored with material they have already mastered (READ: More Standardized Testing: What is the SBAC?). 2. Subject matter Students can take exams in five subject areas. The first category is history and social science, where students can take History of the United States and Human Growth and Development. (This is just a small list of the examinations offered.) Students can also take exams in the categories of composition and literature, science and mathematics, business, and world languages such as French, German, and Spanish. 3. Is Your Child Bilingual? If your child is fluent in a second language, it doesnt make sense for them to pay for a college course in the same language. Taking the CLEP exam is a great opportunity for students to pass out of the subject they already know. 4. Does your child have significant life experience? Some students need to stop attending college for one reason or another but want to go back to school later in life. Adult students who have significant work or military experience may have learned skills that can help them pass one of the CLEP exams. Additionally, some students are very well read and may feel comfortable taking an American literature exam or they may have a knack for college algebra or precalculus, all of which are offered in the series of CLEP exams. 5. How much do the CLEP costs? Each CLEP exam costs $80, according to the College Board. Although this is a significant amount of money for most Americans, it costs a lot less than taking a college level course (READ: Sleep, a Healthy Lifestyle, and Academic Success). 6. How are the CLEP exams scored? The multiple-choice exams are scored by computer and the essays are scored by an English professor chosen by the College Board. The highest score on the CLEP exam is 80 and the lowest is 20. Most students will receive their scores instantly, except for the essays which can take up to a month to be delivered. 7. Which universities accept CLEP exams for credit? Many universities across the US will accept the CLEP exams, however, its important that students speak directly with the universities theyre planning to apply to as theres no hard and fast rule as to whether or not a university will accept these exams. It doesn’t make sense to study for an exam that a student won’t get credit for. In short Although students likely don’t want to add more standardized exams to their schedule, taking a few CLEP exams can certainly make their first two years of college go by faster and might be able to save them a significant amount of money in the long run.

Tips For Choosing a Mathematics Tutor

Tips For Choosing a Mathematics TutorOne of the most helpful aspects of a tutoring system for students who have not yet graduated from high school is the ability to attend classes without fear of distraction or being unable to focus. In addition, many parents can now help their child graduate from school and have a great college experience. When choosing which teaching method will best work for your child, remember that there are a variety of factors to consider such as physical fitness, effort, and the amount of time to dedicate to each subject. To help you choose the best method for your child, the following information should be considered.Studies have shown that students who successfully complete classes in algebra perform better on standardized tests than students who do not take algebra classes. In addition, students who take advanced algebra classes on a regular basis perform better on standardized tests. In the world of mathematics, getting help with algebra is crucial. Altho ugh there are many methods to teach algebra, whether the student has to do the work in a small group or by oneself is up to each individual parent. Parents may even decide to see how much time they have available to spend on their child's math homework.Whether it is a computer tutor, a tutor that teaches through DVDs, a private tutor, or a private tutor that meets in person, a student should make sure that they select a tutor that has a proven track record of success in their algebra class. If your child has difficulty with one subject, then he or she should not expect to succeed in any subject. For example, a child who struggles with algebra may struggle with geometry or trigonometry, too. He or she may find this intimidating because the level of understanding is similar between subjects. What may help with one subject will not help with another.When selecting a tutor for your child, take some time to look around at other tutoring services that are available. Some popular tutoring services include Varsity Tutors, as well as tutoring companies that specialize in either online tutoring or in-person tutoring. A student should try to find tutors in his or her area. That way, he or she can set up an appointment for a tutor to meet with the child. To ensure that the tutor can meet your child's needs, the child should ask questions and ensure that he or she is comfortable with the tutor. Once the tutor meets the student, this is the time to evaluate how well the student is progressing.A tutor should be flexible when making changes to his or her schedule to meet the needs of your child. The tutor should be honest with his or her students and is also sensitive to any expectations that the student may have. Most importantly, the tutor should be able to adapt to the student's ability to learn new concepts, and this should be expressed by how quickly the student is able to grasp new concepts. If the tutor is not able to offer clear explanations for their suggestions, the n this may cause disruption in the learning process.Once your child is comfortable with the tutor, it is important that parents remain engaged in their children's education. Many parents have found that it is helpful to read about how algebra works in order to better understand the concept of algebra. This information should be shared with the child so that he or she can understand what is expected of him or her. Also, be sure that you let the tutor know how much you expect from him or her. It is important to stay in touch with the tutor to make sure that the lessons are progressing according to plan.Once the tutoring sessions are completed, you can review the progress of your child. If any problems were encountered, be sure to contact the tutor immediately. It is also important to see the tutoring company again to see if your child needs additional help with specific areas. Having these issues addressed early will give your child a chance to increase his or her understanding of alg ebra and math concepts.

Solve by Substitution

Solve by Substitution Substitution is a very useful method in mathematics. In the method of substitution one of the variable is substituted to find the other variables and vice versa. It helps reduce the given question or solution to a simpler form. Expressions can consist of one or more than one unknown variables with different coefficients and constant numbers. Example 1: Solve by substitution the set of equations x - 2y = 10 and x + y = 4? Solution: The given equations are x - 2y = 10 and x + y = 4. Here x, y are the unknown variables. Substitute the variable x. From one equation x = 10 + 2y, substituting in the other equation. This gives 10 + 2y + y = 4; 10 + 3y = 4; 3y = -6; y = -2 Now substitute y = -2 in x + y = 4; x = 6. Hence the solution is x = 6 and y = -2. Example 2: Solve by substitution the set of equations x - y = 12 and x + y = 6? Solution: The given equations are x - y = 12 and x + y = 6. Here x, y are the unknown variables. Substitute the variable x. From one equation x = 12 + y, substituting in the other equation. This gives 12+ y + y = 6; 12 + 2y = 6; 2y = -6; y = -3. Now substitute y = -3 in x + y = 6; x = 9. Hence the solution is x = 9 and y = -3.
