Filtrate Definition - An Introduction

Filtrate Definition - An IntroductionFiltrate definition is the study of any substance in its molecular structure, as it exists in nature. The study of chemical filtration and identification is the basic responsibility of the filtration laboratory. This includes the act of gas chromatography, liquid chromatography, gas chromatography, radio-purification, ionization mass spectrometry, and gas chromatography/mass spectrometry (GC/MS). Through this study, the physical, chemical, and biological properties of the substances are determined.Chemical filtration can also refer to any of several types of chemical methods used to separate chemicals from other materials, such as volatile organic compounds (VOCs), water, and gases. VOCs are the leading contributors to airborne pollution. VOCs include gasoline, chlorine, diesel, and other petroleum products. Water filtration uses ion exchange to remove dissolved impurities. Gas chromatography utilizes vacuum energy to separate chemicals, such as p etroleum products, VOCs, and some metals, in water.Filtrate definition should not be confused with the word filtration. There are a number of different types of filtration methods, all of which must be used according to specific guidelines. A chemical filtration method will help identify the components of a substance, but will not provide knowledge of the nature of that substance.To further define filtrate definition, it is useful to think of the distinction between physical and chemical filtration. Physical filtration is the study of a substance in its molecular form. Examples of physical filtration methods include steam distillation, gas chromatography, and the carbon-based pump. The more common of these methods are the two mentioned above.Chemical filtration is used to reduce the amount of pollutants that enter the water supply, especially for smaller scale applications. It includes the use of purification technologies, such as reverse osmosis, advanced precipitation filters, and membrane-based systems. These chemical filtration technologies, such as membrane-based systems, have also been found to be effective in eliminating contaminants not found in smaller scale applications.Chemical purification is used in public water treatment facilities for flushing out chemical contaminants before using them in water supply applications. One of the latest and most popular chemical purification technologies is the ion exchange. This technique takes advantage of the surface tension between oxygen and molecules, to carry out chemical purification.Chemical purification technology can be used to remove pollutants before they reach public water supplies. In some cases, it can also be used in private water systems to improve quality and remove chemicals that cause illness.

Converting mixed numbers and improper fractions

Converting mixed numbers and improper fractions Fraction are very commonly used and very important form of representation of numbers. Fraction is usually written in the p/q form. Here p is the numerator and q is the denominator. The denominator of a fraction cannot be equal to zero i.e. q not equal to zero. Fraction where the numerator is lesser than the denominator p q is called as a proper fraction. A fraction where the numerator is greater than the denominator is called as improper fraction p q. An improper fraction can be converted to a mixed fraction. A mixed fraction is the combination of a whole number and a proper fraction. Example 1: Convert the mixed number 1 to improper fraction? Solution: The number is a mixed number 1 where 1 is the whole number part and is the proper fraction as the numerator is lesser than the denominator i.e. 3 4. The mixed number can be now converted to improper fraction. Therefore, 1 = (4*1 + 3)/ 4 = (4 + 3)/4 = 7/4 This gives 7/4 which is an improper fraction as 7 4. Hence, the mixed fraction gives 1 can be expressed as 7/4. Question: Multiple choice question (Pick the correct option.) Convert the mixed number 6 into improper fraction? a) 13/2 b) 7/2 c) 11/2 d) None of these. Correct answer: option a. The mixed number 6 can be now converted to improper fraction. Therefore, 6 = (6*2 + 1)/2 = (12 + 1)/2 = 13/2. This gives 13/2 which is an improper fraction.

Tuition At Foreign Colleges

Tuition At Foreign Colleges There are many adjectives people use to describe college: expensive, affordable, appropriate, valuable to name a few. But, free is rarely one of them. Free is one of the many appropriate adjectives used to describe the University of Helsinki, located in Finland, according to an article in The US News World Report. Another adjective is the 75th-best college in the world, well compound adjective. The University of Helsinki is tuition-free for American students, meaning students will still have to pay for books, rent and travel expenses. The US News World Report estimated that a bachelors degree at this college would cost an American student $40,000, assuming a student could live on less than $1,000 per month. Its total cost is significantly less, compared to the-similarly ranked University of California San Diego, which is ranked 65th on The US News World Reports worldwide college rankings. Its tuition has reached $28,000, bumping its cost of attaining a bachelors degree over $120,000, assuming the student receives no financial aid. There are also some top-ranked Scandinavian universities that are tuition-free. Tuition costs for American, British and Australian colleges are skyrocketing. So, other foreign countries are lowering their tuition costs, offering more courses in English and allowing students to acquire bachelors degrees in three years. These efforts are in attempts to attract more American and foreign students. Most notably, the University of Hong Kong, some of the top Korean universities, the University of Amsterdam, and others are now offering classes in English. The article estimated that a students total cost of acquiring a bachelors degree from some of these universities would be about $70,000, including text books, travel expenses, tuition etc. Also, some of these colleges offer significantly cheaper bachelors programs to foreign students who can speak the countrys native language. This could save students around $20,000. There are still several downsides to attending a foreign college. Typically, colleges reserve most of their financial aid funds for native students. So, an American student is unlikely to receive significant financial aid to a foreign college and could end up paying less by attending an American college. Although these schools are ranked highly, they may not have the name recognition of American schools. Future employers wont know the caliber of the foreign school you may attend, and chances are they wont look into it either. And for those who miss home easily: a foreign college takes homesickness to a completely different level with a different culture and language.

What are the High School Science Courses

What are the High School Science Courses While most people are familiar with chemistry and biology, there happen to be a great number of science courses available to high school students. Some are required and others are optional, but each offers a leg up to students eyeing colleges or hoping to seek a career in the sciences. As STEM (science, technology, engineering, math) programs gain momentum, there are more science classes available than ever before. [RELATED: STEM Resources for Students] So, what options are available to students with an interest or background in science? While this list may not be exhaustive, it covers the vast majority offered in public high school systems (students are typically required to take between two and three years of science curriculum). Biology Biology is typically the first science class that high school students take. It focuses less on math, allowing students to enroll in a variety of math classes before being required to apply those skills in science classes. In biology, students will cover cells, organisms (and how they relate to the environment around them), ecology, genetics, and human growth and development. Often, students who prefer non-science subjects tend to enjoy biology, as it eases them into harder sciences while providing a good educational foundation. Chemistry Chemistry is typically taken next and involves slightly more math than a biology class. Students in chemistry classes will study reaction rates, chemical energy, the concept of moles, and acids and bases. Students may either love or hate chemistry, though with proper preparation and a good teacher, it can be fun! To be successful in chemistry class, students should pay careful attention and use practice problemsthe math required can get easier if you consistently work on it! Physical/Earth Science Physical/Earth Science typically covers organic chemistry, chemical bonding, stoichiometry, rock types, and atmospheric science. While some schools call this course either Physical Science or Earth Science, the coursework is similar. Students may take this course in their junior year of high school; sometimes, they may have the choice between it and physics. Physical/Earth Science may be a better choice for you if youre less confident in science or have a harder time with math. Physics Students may choose to take physics because it can look stronger on college applications, as it typically presents a higher level of difficulty. In a junior year physics class, expect to cover concepts relating to matter, space and time, motion and forces, optics and light, magnetism and electricity, and atomic physics. Be prepared for a challenge. Elective Science Coursework... Often, students who take science the first three years of high school are not required to take a science course during their senior year. However, those who wish to continue studying science or math (or who otherwise find science interesting) may choose to enroll in additional science courses. The following elective courses can build upon skills learned in earlier science courses. [RELATED: 4 Benefits of STEM Studies] Environmental Science In this class, students should expect to cover topics related to the application of environmental analysis. Topics will include energy, atmosphere, land, water, and ecological structures. Students will also learn about data collection and reaching conclusions based on research and experimentation. Forensic Science In a forensic science class, a student should expect a class that is more focused on scientific process. While theres bound to be plenty of exciting (fictional) crime scene analysis, the class is also interested in law and courtroom procedure, data collection, hypothesis formation and testing, and lab work. Astronomy Not to be confused with astrology, astronomy focuses not on the horoscopes in the Sunday paper but the science behind the stars. Students will study black holes, history and development of the solar system, laws of gravity and motion, and methods of research. As you can see from the variety of classes listed, there are many avenues of science from which students can learn! If you feel this is one of your weaker subjects, consider seeking science tutoring or meeting with your teachers to see what kind of assistance they can recommend.

College Biology Online Biology Tutors Tutorpace

College Biology Online Biology Tutors Tutorpace With a few exceptions every organism is considered to be either a plant or an animal. The study of plants is called botany and the study of animals is called zoology. In addition to these two divisions, another branch of biology which has come into prominence in recent years is microbiology. It is the study of such plants and animals which are so small that can be seen only with the help of a microscope. Microbiology deals chiefly with the organisms which cause diseases. The distinction between these three subjects is based on the nature of organisms. Within two broad subdivisions (Botany and Zoology), there are still smaller fields devoted to the study of a particular group of plants and animals. Each of this field forms a distinct branch of Biology and is given a specific name. Morphology: Branch of Biology which deals with the configuration and the structural form of any organisms. It is subdivided into two-anatomy and histology. Cytology: It is the study of cells. Embryology: It is the study of sequences of growth and development of plants and animals and deals with the formation and development of the embryo. Ecology: It deals with the study of organisms in relation to living and nonliving surroundings. Genetics: The branch which deals with heredity and variation Evolution: It deals with the transformation. Taxonomy: It is the branch dealing with the naming and classification of living organisms Physiology: It deals with the functional aspects of various parts of the organisms

Build Your French Vocabulary How to Tell Time in French

Build Your French Vocabulary How to Tell Time in French Suzy S. For our last French vocabulary lesson, tutor Carol Beth L. taught us numbers, counting, and basic math. Now, its time to put that knowledge to work with this lesson on telling time in French So, are you confident with your numbers in French yet? Telling time is a wonderful way to practice â€" and is very helpful in everyday life! Lets start with a few basic words and phrases: Heure hour Lheure the time Quelle heure est-il? What time is it? (Say: Kel Ur [like the city] ay-teel) Il est ______ heures. It is ___ oclock. Midi noon (12pm) Minuit [say: mee noo ee] midnight (12am) In the question “Quelle heure est-il,” for the purposes of pronunciation, it is helpful to be aware of the concept of the liaison in French. When one word begins with a vowel sound, but the preceding word ends with a silent consonant, that consonant is pronounced almost as if it were the first letter of the next word. This is why the “t” in “est” is pronounced the way it is â€" but the “s,” which is also normally silent, is not. Lets look at a few examples: Susie: Quelle heure est-il? What time is it? Alain: Il est 9 (neuf) heures. It is 9 oclock. Alain: Quelle heure est-il? What time is it? Susie: Il est midi. Allons manger! It is noon. Lets go eat! In France, it is important to realize that the people you are speaking to will measure time on the 24-hour clock, often referred to as military time in the United States. So for any hour in the afternoon or evening, you will need to add 12 to the number we usually use for the hour in the United States: 13:00 = 1pm 14:00 = 2pm 15:00 = 3pm 16:00 = 4pm 17:00 = 5pm 18:00 = 6pm 19:00 = 7pm 20:00 = 8pm 21:00 = 9pm 22:00 = 10pm 23:00 = 11pm Here are a few examples of how this would be used in context: Il est 13 (treize) heures. (It is 1:00 in the afternoon. Literally: It is 13 oclock.) Il est 18 (dix-huit) heures. (It is 6:00 in the evening. Literally: It is 18 oclock.) So what about the times in between? Here, a little more vocabulary will help us out: ______ heures et quart a quarter past ______ ______ heures et demie half past ______ ______ heures moins le quart a quarter to ______ Again, lets see this in context: 1) Il est minuit moins le quart. (Its a quarter to midnight. Or equivalently: Its 11:45pm.) 2) Il est 15 (quinze) heures et demie. (Its a quarter past three in the afternoon. Or equivalently: Its 3:15pm.) 3) Il est 7 (sept) heures et quart. (Its a quarter past seven in the morning. Or equivalently: Its 7:15am.) Note that in the French version, “in the morning” or “in the afternoon” (indicated in the English translation) is implied because they use the 24-hour clock. These three vocabulary terms “et quart,” “et demie,” and “moins le quart” often require more practice for American students than the style that comes next, but they are used relatively often. You may wish to focus on practicing telling time using this format until it feels natural to you before moving on. Try looking at a clock at random times throughout the day and telling the time according to the nearest quarter-hour. Or if you have a “will return at” sign with a moveable clock on it, have a friend show you random times of their choosing, and give them the time (again, to the nearest quarter-hour) in French. You or a friend can also draw clocks with desirable times on them. So what if you need to be more precise than telling time to the quarter-hour? In English, we might say “Its ten-oh-three,” or “Its eleven fifty-seven.” In French, you can do almost the same thing: Il est dix heures trois. (Its 10:03 am.) Il est onze heures cinquante-sept. (Its 11:57 am.) Il est dix-sept heures vingt-neuf. (Its 5:29 pm.) Il est midi quarante-deux. (Its 12:42 pm.) In these and similar cases, be sure to include the word “heures” in your sentence between the hour and the minutes. We do not include it in English, but it is important in French. Now, you have several ways to tell time in French. If you recently learned to count in French, it is also an excellent way to practice your numbers. Practice your French vocabulary consistently and telling time â€" and numbers â€" will become second nature. For more help learning to speak French, why not try studying with a private tutor?

English Phrases Related to Relocation ?? - Learn English with Harry

English Phrases Related to Relocation ?? - Learn English with Harry Many of you I am sure have or will at some time in the future relocate to an English speaking  country. Here is my experience with some English phrases related to relocation.Moving home is a very stressful  (worrying) time and is the top 4 list of the most stressful  (comparative format of stressful) life experiences. I believe that when you relocate to another country  then that stress is multiplied by a factor of 2 or 3  (two or three times greater). English Phrases Related to Relocation I recently relocated within Europe but to a different country. The idea of a move  (relocation) is  always exciting and a bit of an adventure. However, when you actually do it and try to organise  everything to fall into place  (to happen at the same time) it can be extremely tricky  (difficult) as  problems you did not envisage  (think about) arise and knock you off track  (delay or prevent you  from completing your task).Usually, you need to have an apartment selected  (chosen) before you arrive unless you are going to  spend some time living out of a suitcase  (literally all your clothes in a suitcase in a hotel room). You  need to locate an apartment but it is impossible without the help of a real estate agent  (realtor,  a person who sells and rents out apartments and houses)  who knows the market in the city you are moving to.  Then you have to, as happened with me, register with the local authorities but to do that you need a permanent address. So it is a bit of a  chicken and egg situation! (What came first the chicken or the egg? What do you do first?) so should  you register first or rent? Then you need to organise utilities  (phone, internet, water, electricity and  heating). English Vocabulary related to Relocation - Infographic Enjoyed this infographic? Here’s what you can do next: These are all achievable  (can be done) assuming there is no language issues. There was of course in  my situation as I did not speak the local language. Luckily I discovered  (found) a specialist who  assisted poor people like me and offered to bring me around  (introduce me to) the appropriate  services that I needed. This of course cost me a fee but it was invaluable  (very useful).Of course, in the modern world of a cashless society  (credit and debit cards only) you also need to  have a local bank account so that rent payments and utility bills can be set up  (arranged) as direct  debits  on your account (payments that are deducted monthly from your account).It always works out well in the end  (eventually) and you can start to enjoy your new surroundings.Here are some other English phrases related to relocation:To up sticks   to pack everything you have and move somewhere newPastures new   like a horse when it finishes eating the grass around him will move on. So when we  move on we go to pastures new.Greener pastures   similar to pastures new. To move on to something better.Home is where the heart is   houses and flats are made of bricks. The real home is where your heart  is.
