What Is Colloidal Chemistry?

What Is Colloidal Chemistry?Colloidal Chemistry is the science of chemistry that deals with the distribution of various salts in its process. This is the science of colloidal particles that are formed through the movement of the various minerals such as salt, carbonate, chloride, sulfate, magnesium, iron and calcium.Inorganic and organic molecules that are in contact with each other can be classified into two categories. These are termed as colloidal and non-colloidal. Non-colloidal colloids are called as products of body fluids, whereas colloidal products are formed through the movement of air, water and oil.There are two types of colloidal colloids. They are the non-metallic colloids and the metallic colloids. All the colloids contain an element that serves as a carrier for the compounds in it. It helps to create a uniform ionic density which is necessary for creating a specific chemical compound.These compounds can be used to produce certain results. For example the colloid known as Emu Oil can be used to fight acne. It is also used to cure various skin problems.The major functions of colloids are to lubricate and protect the body from injury or infections. The fluid carries the dust and other impurities into the body through the skin.Different colloidal minerals can be divided into three groups. These are the colloids that are produced by living organisms, those that are formed by inorganic substances such as sodium, potassium, phosphorus, etc. and those that are produced by living materials such as the saliva, urine, sweat, mucus, etc.To prevent diseases and the possible ailments that might happen, colloidal substances such as salt, borate, CO2, argon, phenol, sodium chloride, and the like, have been used as remedies. Besides these, colloidal minerals such as magnesium and calcium are also known to be good for the health. Colloidal minerals such as magnesium and calcium are helpful to maintain the proper functioning of our immune system.Colloidal substance s are believed to be safe, with the exception of a few known toxins. Some of the known toxins that can cause harm to the body are lead, arsenic, mercury, cadmium, and cyanide.

English Literature a classic A-level choice

English Literature a classic A-level choice Competition for university places is particularly fierce, thanks in part to the new generation of A*grades coupled with a drop in available university places as funding for higher education decreases. As it becomes acutely important for candidates to stand out, hiring a personal tutor is an excellent way of cultivating an edge for prospective university students. There has been much news in the papers recently about the lack of validity of certain A-level subjects in connection with the competition for university places. Many deans have spoken out about the need to take more traditional subjects as opposed to newer subjects, which may not be taken as seriously by admissions tutors. Choosing a classic academic A-level subject augmented by regular tuition can help a student to differentiate themselves from the competition, especially when applying for places at Oxbridge and the Russell Group universities. English Literature is such an A-level subject. It is traditional, academically rigorous and highly regarded by all of the universities. English Literature prepares students very well for university study because it involves heavy amounts of reading, research and essay writing. It also encourages students to be precise yet engaging in their writing and to energize their critical faculties, both in class discussions and in essay writing. English Literature A-level involves the study of various texts, including poetry, plays and novels from classic and modern authors as well as criticism from a range of perspectives. For those students who wish to gain the most from their A-level study, First Tutors can recommend a host of specialists in English Literature. Browse our database for a specialist tutor near you.

I beat the italki 2014 World Cup!

I beat the italki 2014 World Cup! We received this great message from Jeremy who finished the 2014 World Cup Language Challenge learning Chinese!   Originally posted on his personal blog, we enjoyed it so much that we wanted to share it with everyone.  Great job Jeremy and keep up the great work!  Re-posted with permission. Italki 2014 World Cup is over! I beat the italki 2014 World Cup! Ok, alright, you can stop cheering now. The challenge wrapped up over the weekend and I was notified today that I was successful. So now that Im filthy rich, I plan to keep learning Chinese, instead of retiring to the Bahamas. I know, I am a wild one. What is italki 2014 World Cup? In short I put up 200 ITC ($20) pledging to spend 25 hours language learning through their site, within a 60 day period. If I win I get 400 ITC ($40) and my bet returned. This should be an easily attainable goal of about three lessons a week during the 2 month duration of the challenge. Surprisingly only 53% completed the challenge. They have some cool stats on most hours completed by country, and most hours completed by language, if youre interested. Thanks italki for being awesome! I want to thank italki for putting on the challenge and being so encouraging. I think they did several helpful things for us participants. They encouraged people to make a video pledge and post it onto their FB, G+, or the like. Their data showed that people who did this were more likely to complete the pledge. Another thing was they put up a big FAQ page full of useful info. I checked it a few times. They also reminded you via the website message system weekly about the challenge. This reminder would let you know roughly how many hours you should have completed, and what the current leaderboard looked like. Another thing that was nice was the countdown clock on the main site. You knew exactly how much time you had left. What I hope they do for next time is add a hours scored, or #/25 completed section up there also. Currently you have to go to sessions and do a manual count if you wanted to know how far along you are. How did I do? My work towards completion was not linear. With holidays, and business trips in the middle, I had to be mindful of my schedule. To compensate for my traveling I did roughly 4 sessions a week during the first 2 weeks and the last 2 weeks. Even with one trip to Colorado, and another to Florida I ended up clocking in 31 hours. Thats just over 3.5 hours a week. Not too shabby in my opinion. Whats Next? With this challenge completed I look forward to the next italki challenge. In the mean time my next big Chinese goal is the HSK IV. I take it this month on the 17th. Im not yet ready for it, but I am working towards that as fast as possible. Wish me luck! Everyone here at italki wishes Jeremy good luck with his HSK IV test.   I beat the italki 2014 World Cup!

5 Bad Habits That Are Wrecking Your Vocal Cords

5 Bad Habits That Are Wrecking Your Vocal Cords Sign up successful Bonus: Staying hydrated will also benefit your overall health, helping you to avoid infections and colds. Even mild dehydration can affect your bodys efficiency, leading to ailments like headaches and fatigue. 2. Relying on caffeine or alcohol. Similar to point #1, avoid the overuse of caffeine and alcohol, which both lead to dehydration. Alcohol causes the muscles in your throat to constrict, which may affect your range, and caffeine contributes to excessive dryness in the throat. While a cup of coffee to wake you up or one drink to calm your nerves before a show arent going to necessarily ruin your performance, its best to limit these drinks. And if you must have one, follow it up with an extra glass of water. 3. Skipping your warm-ups. Back to the athlete comparison: Similar to how the athlete needs to warm up the muscles in his or her body, warming up each limb to prevent injuries and help with overall performance, a singer should take vocal warm-ups into account before each and every practice session. Your voice teacher can show you various warm-ups to try, but a few popular strategies are lip trills, humming in an ascending and then descending pattern, and singing vowels in the same pattern. Your warm-up should leave your voice and throat relaxed, and your breathing under control. (Want some extra warm-up tips? Download our free singing video series here.) 4. Overusing your voice. Imagine youre at a loud concert or event. The music is so loud, you have to yell to speak to a friend standing right next to you. You might not think twice about it at the time, but do this all night, and youll leave the show as hoarse as a teenage girl screaming at a Justin Bieber concert. Do this often, and youre putting yourself at risk for a vocal injury. This also applies to everyday practice sessions. Keep yourself hydrated (seeing a pattern here?), and take breaks every so often to avoid overuse. Lastly, if you have a performance coming up, try to rest your voice as much as possible before (and after!) the event. 5. Belting without proper training. Belting, a style of singing that produces volume and power, can be extremely dangerous for singers who arent trained properly. Without this training, you may end up forcing some of the notes, which can lead to vocal cord damage and trauma. Healthy belting takes a lot of practice, and not all voices are made to do so but luckily, there are other strategies you can use to generate power. Some singers take years to train their voices to belt naturally and properly. Find a singing teacher with specific training, and discuss your goals. Its recommended that you master breath control, pitch and other mechanics of singing before attempting to learn how to belt. You might also like What Can I Expect At My First Voice Lesson?

What is it Like to Attend Oberlin College

What is it Like to Attend Oberlin College The tutors behind Varsity Tutors are not just here to teach theyre sharing their college experiences as well. Alexandra earned her bachelors degree in biology at Oberlin College and is pursuing a masters degree in elementary education at John Hopkins University. She lives in Chicago and specializes in ACT Science tutoring, ACT Reading tutoring, writing tutoring, and several other subjects. See what she had to say about her experience at Oberlin College: Describe the campus setting and transportation options at Oberlin College. Alexandra:Oberlin College is in the very small town of Oberlin, OH, about 40 minutes west of Cleveland. The campus is small, and all academic buildings are located within a few square blocks of each other. All student housing is within one mile of campus, but most is a lot closer than that. The campus is extremely safe. I am female and felt completely safe walking by myself at any time of day, including in the middle of the night. There are no campus buses because the campus is so small. You only need a car if you want to leave Oberlin very often. A car is not necessary because most people know at least one person with a car who can take you to the store when you need to go. Things like CVS and the grocery store are all within walking or biking distance of the school. A lot of students at Oberlin have bikes because it makes it easier to get around the campus more quickly. They also have free bike storage during the winter. How available are the professors, academic advisers, and teaching assistants? Alexandra:My professors were always very available to students and willing to meet outside of class, either during office hours or at a mutually agreed upon time. They were responsive via email, and a lot of professors even invited students to their homes. Academic advisers were also easily available by email and appointment. One nice thing about Oberlin is that the school is so small that all of your professors and your adviser know your name and remember things about you. All of the teaching assistants I had were very helpful and held study sessions multiple times per week outside of class. I was also a teaching assistant for multiple years and made an effort to get to know my students and make myself available to them. How would you describe the dorm life rooms, dining options, location, socialization opportunities with other students? Alexandra:Dorm life in Oberlin is good. The dorms are old, but they are usually clean and have everything you need. I lived in two doubles, a single, and in a room in an on-campus house, and I was satisfied with all of those living situations. I liked most of the people who lived in my dorm, and there were constantly campus events and concerts at the Conservatory that we went to together. There are two main dining halls on campus (Stevenson and Dascomb) and one takeout/convenience store-type place (DeCafe). Athletes and people on north campus mostly ate at Stevenson, and everyone else ate at Dascomb mostly because of physical proximity. Stevenson and Dascomb had pretty decent food options, and the school is vegetarian/vegan friendly. At DeCafe, you can order smoothies, sandwiches, and salads, as well as buy other snacks and groceries. The food at DeCafe was awesome, but you cannot use meals there you have to pay cash or use your meal plan flex dollars. If you do not want to eat in dining halls, you have the option of joining a co-op. There are several co-ops on campus they are generally cheaper than eating in the dining hall, and you have to do co-op work duty on a regular basis. You cannot eat both in co-ops and in the dining hall. You have to decide to either eat all of your meals in a co-op or eat all of your meals in the dining hall. Which majors/programs are best represented and supported at Oberlin College? Alexandra:I studied biology so I am biased in answering this question. Oberlin has strong science programs biology, chemistry, physics, and neuroscience. The environmental science program is also large and well-known. Beyond that, I would ask an admissions representative because I do not know much about non-science-related programs. I studied biology because I was premed until the fall of my senior year. I have always loved science I had a hard time deciding between neuroscience and biology at Oberlin because I loved both of the programs so much. I also have a chemistry minor. I felt very supported in my major by both professors and students. How easy or difficult was it for you to meet people and make friends as a freshman? Does Greek life play a significant role in the campus social life? Alexandra:One of the reasons I chose Oberlin was that it has NO Greek life. It was easy to meet people freshman year because everyone was looking for friends, and they also had a lot of freshman socialization opportunities, especially during freshman orientation week. Clubs are really big at Oberlin, so people make a lot of friends through clubs and other activities they do. I was shy and did not find my core group of friends until the beginning of my junior year, but they became like my family. I live hundreds of miles from all of them now, but I have seen everyone at least once since we graduated, and we all talk on a regular basis. How helpful is the Career Centerand other student support services? Alexandra:The career center helped me find the job I am currently at today. They were very helpful when I was writing my resume and looking for summer opportunities, and they told me about the job I ended up applying for and getting. I know of a lot of students who had similarly positive experiences. My professors were also very helpful with ideas for job/program hunting and resume help. I do not know which companies recruit on campus. The Oberlin alumni network is very strong, and I know a lot of people who got jobs and internships from other Oberlin grads. How are the various study areas such aslibraries, the student union, and dorm lounges? Alexandra:There is an endless supply of study space at Oberlin. There are large common rooms in dorms, multiple libraries, and various nooks and spaces in several academic buildings. You choose your study space based on the environment you are looking for. If you want to hang out with friends and talk while you do work, you might go to the library caf or a dorm common room, but if you want somewhere silent you can go to the science library. The science library is generally less crowded than the main campus library, but I was always able to find space no matter where I wanted to study. Describe the surrounding town. Alexandra:Oberlin is a very small town and is split into the student side and the townie side. The main green space in downtown Oberlin is called Tappan Square. The campus is located mostly on one side of Tappan, and townies live on the other side. The main strip with all of the stores and restaurants in Oberlin is located along Tappan Square. Not very many townies set foot on campus property because college security discourages this. Townies and students intermingle in downtown Oberlin and there is no major tension. There are several restaurants in town and one main bar, The Feve, which is awesome. Oberlin gets a little small and boring after a while, so it is nice to befriend someone with a car who will periodically take you off campus. Students go downtown very often (there are also two coffee shops for studying) because the campus and downtown are so close to each other. How big or small is the student body at Oberlin College? Were you generally pleased or displeased with the typical class sizes? Alexandra:I think there are about 2,200 undergraduate students at Oberlin. I went to a high school of 400 students and wanted to go to a small college, so the size of the student body was perfect for me. I was always very happy with my class sizes. Intro biology had over 100 students, and that was by far my largest class. Most of my classes had 15-25 students. Describe one memorable experience with a professor and/or class. Perhaps one you loved the most or one youregretthe most. Alexandra: My absolute favorite class at Oberlin was Vertebrate Structure and Evolution, a biology class with Professor McCormick, who is now retired. It was so difficult we had to memorize so many facts and bones and structures but I learned more from that class than any class I have ever taken. We also got to dissect several animals, and I really enjoyed that. View more ACT tutorsnear you. The views expressed in this article do not necessarily represent the views of Varsity Tutors.
