Investing in Solid Metal Finishes: Surface Chemistry

Investing in Solid Metal Finishes: Surface ChemistrySurface chemistry can be defined as the properties of a material that affect its ability to conduct electricity. The properties include the degree of intermolecular bonding, the percentage of solute in solution, and the typical porosity of the material. Surfaces contain large molecules like water and oil. These types of molecules are too large to be included in most metal alloys and thus are easily corroded and dissolved in the resulting solution.In addition, the surface chemistry of a piece of metal generally influences the way it is bent. When the metal is bent, that in turn can impact the corrosion of the metal and can affect the availability of electrical current.If a metal does not corrode well then the piece may be cooled and melted into a liquid state. Then, this liquid can be drawn back into the metal through a channel. Unfortunately, if there is too much movement of the liquid back into the metal the electrochemical reactio ns will cease.In addition, such liquid will typically flow out of the channel quickly and again the process will stop if enough force is exerted. Unfortunately, if you try to pull the metal back in for repeat applications then you will increase the rate of corrosion of the metal as a whole.This could have significant impacts on the energy needed to perform the task of drawing current from the wall outlet. Additionally, if the valve does not close properly, the current flow will be slowed or halted altogether. And once the valve is closed, it can have a significant impact on the current flow within the home.If you want to determine how corrosive the specific materials you can use the following tips. While all metals do experience corrosion at some level, copper and other lower conductor metals are more easily damaged than stainless steel and metals that exhibit many ions.Always ensure that the surface chemistry of the piece you are handling is stable. It is also important to ensure t hat any work surfaces are cleaned carefully with flame retardant chemicals. The work surfaces should also be covered with protective gloves so that they are not exposed to the fumes from welding or any other chemical processes.Protecting yourself and your family against potential corrosive agents in the home is certainly a responsibility that goes beyond a homeowner's maintenance needs. And your local building department should be able to offer advice on protecting your family and your household items. If you take some time and do your homework then you will be able to keep your family safe and protected.

3 Reasons Why Good Students Get Bad English Grades

3 Reasons Why Good Students Get Bad English Grades In my experience as an English tutor, I find that it is not only students who struggle with English that can get poor grades. Good students can also get bad grades in papers and exams. Here are three reasons why. 1. They over-prepare.When you have been assigned a paper thorough research is important. But there is such a thing as too much research. I have had students who had to write papers on Shakespeare plays who knew the plays backwards and forwards. They were also experts on scholarly interpretation of the plays. However, with so much research they lost sight of the key points they wanted to make in their papers and in their exams. As a result, they produced poorly structured essays which had too many ideas that were not properly developed. The best essays might have only three to five ideas that are well developed. 2. They do not do enough timed exam practice.Revision is not only about reviewing your notes and re-reading set texts. A core component must be timed exam practice. I have yet to see a student that consistently does well in timed assessments that has not practiced questions under timed conditions. This is essential for two reasons. Students must learn to read and understand a question quickly. They must also learn to manage time in exams. They should leave enough time to create a writing plan and write a conclusion. Those who do not leave time to plan rarely produce as essays of the same quality as those students that do. Those who do not conclude their essays give the marker the impression of an unfinished piece of work. Both situations should be avoided. Time management in exams is vital for getting high grades. Students who do not manage their time carefully in exams often lose easy marks. I once had a student who lost 30% on his English Literature exam because he did not answer a third question, only completing two out of three. Unfortunately, the third question was one he could have answered well. 3. They read too quickly.While slow readers often struggle with text comprehension, I have found that good readers sometimes also perform poorly in reading comprehension. This is because with their faster reading pace they start breezing through a text without clarifying the purpose of their reading. There is a balance between speed and clarity of purpose. Students need to consciously ask themselves what it is that they want to learn from the text. This encourages targeted reading which often leads to higher scores on reading compression tests.

How To Improve Your Med School Application

How To Improve Your Med School Application The list of factors to determine if you will be accepted into a certain medical school can go from your MCAT scores/undergrad GPA all the way down to your hometown. But, the objective factors such as MCATscore, GPA, courses taken, etc., are fairly easy to measure and compare to other students. Other subjective factors like interview score, research/work experience, etc are much more difficult to compare but can still impact your outcome. So, here is what you need to get into the top med schools: GPA: Most med schools want to see at least a 3.5 GPA. Your GPA can be a fairly objective measurement; however, many undergrad schools are known for grade inflation, and med school admissions officers know which ones are. So, a 3.7 at Ohio State University is not necessarily comparable to a 3.7 at Yale University. Curriculum: Most med schools (not just the top schools) require at least one year of the following courses: General biology Physics with lab General chemistry(inorganic chemistry) with lab Organic chemistry with lab Calculus English MCAT: This is the most objective factor in your med school admissions process because every students test is weighted/scored the same, making scores easily comparable. Your MCAT score very well could be the most important factor. Average 2011 MCAT scores for the top 10 med schools, as ranked by the US News World Report: Note: These are not total scores, but rather the average of the three-multiple choice scores. 1. Harvard University: 11.9 2. University of Pennsylvania: 11.6 3. Johns Hopkins University: 11.8 4.Washington University in St. Louis: 12.5 5. Duke University: 11.5 5. Stanford University: 11.6 5. University of CaliforniaSan Francisco: 11.4 5. Yale University: 11.3 9. University of Washington: 10.5 10. Columbia University: 11.8 Top 10 med schools with strictest MCAT requirements 1.

Brown Medical School: 11.7 7. University of Michigan: 11.7 8. Baylor College of Medicine: 11.6 9. Stanford University: 11.6 10. University of Chicago: 11.6 -MCAT scores according to the Medical and Societal Journal of a Vitreo-Retinal Surgeon. In-state vs Out-of-state: Your chances may be better at in-state schools. Many of the public med schools (including the top schools) are more lenient toward in-state students; however, not all of them are. This leniency is not nearly as strong in private schools as it is in public schools. Research: This would quality as a subjective factor; however, any student can still create a strong research project. Having research to show can only help your chances, but it is optional. Its best to start your research project early and work with a trusted faculty advisor. Be prepared to discuss and defend your findings in a future interview.

Lets Learn How to Play the Cittern.

Let’s Learn How to Play the Cittern. What You Need to Know Before Learning to Play the Cittern. ChaptersWhat is the Cittern?Some Famous Cittern Performers.How to Play the Cittern.Where to Find Cittern Lessons.We imagine that the world is split into two types of people: those who have never heard of the cittern, and those who desperately want to get their hands on this musical instrument and get playing.Considering that you have found yourself here, we are guessing that you belong in the second category â€" although you might not put it in those terms. And our project here is to have you fulfil your desire: to get you playing this stringed instrument and taking its music to everyone in that first category.And we’ll admit it. Out of all the musical instruments that you can possibly learn in the world, the cittern is up there with the mandolin or the harpsichord as one of more obscure stringed instruments. It’s not exactly like the modern guitar, is it, or violins, for which you can find lessons and training on pretty much every corner of every street.No, it isn’t. If you wa nt to learn to play the cittern, you have to make a bit more of an effort. You need to find out how to tune it, what notes the strings are supposed to be â€" and then find the correct strumming or plucking technique, and all the pieces in the repertoire that you’ll want to play.You’ll never take for granted how easy it is to learn the guitar ever again.So, here, we’re going to give you all the information that you might need before you sit down and start learning the cittern: a bit of the instrument’s history, some famous citternists you need to know, and some basic techniques.And we’ll finish off by pointing you in the direction of some cittern teachers â€" to make your life a bit easier.

However, where with a mandolin you use a plectrum, on the cittern you primarily just use your fingers.Meanwhile, whilst mandolins are reasonably widespread as instruments, citterns are not so much. And, importantly, they only come in one shape. There are not all these differences between flat-backed and bowl-shaped citterns that you find in mandolins. Citterns are flat-backed â€" making them easier and cheaper to make.However, the primary difference between the cittern and the mandolin is in their history. They are two distinct instruments with two distinct trajectories. But, given their history â€" and the fact that the cittern is a primarily historical instrument â€" all of these terms tend to become a little confused.And so, despite the cittern’s history, it can often be very similar â€" and often confused â€" with a mandolin, a mandola, or even a bouzouki.A Brief History of the Cittern.The cittern comes f rom the family of lutes and it was popular across Europe in the sixteenth to the eighteenth centuries. It is generally thought to have developed from the earlier instrument, the citole, which is considered to be the ancestor of the modern-day fiddle.Whilst most string instruments during the Renaissance used gut strings, the cittern made use of metal, which were placed over a fretted neck and what is known as a ‘pear-shaped body’ â€" as opposed to the contemporary guitar’s double-shouldered shape.Just as the guitar is now, the cittern was a popular instrument, with popular in the sense of it being an instrument of the people rather than, say, of the aristocracy. There are even references to citterns being in barber shop waiting rooms, so that people could play as they waited.However, by the end of the eighteenth century, the guitar had started to push the cittern aside, in terms of popularity and distribution. Apart from in Germany and Switzerland, where citterns were still bei ng commonly made and played, they generally stopped being used across Europe.Stefan Sobell, an English luthier, has, since the seventies, been making instruments that he calls ‘citterns’. This is essentially an octave mandolin but with five courses â€" again suggesting that the distinction between the mandolin and the cittern is not so rigid.Check out how to learn the ukulele too! 'The Duel', by Cornelis Saftleven - featuring the citternSome Famous Cittern Performers.Well, okay, maybe ‘famous’ is pushing it a little; as in the world of the lute and other string instruments, no-one is exactly famous in the world of the cittern.However, it is good to know that there are some citternists out there from whom you can draw some inspiration. Because that, really, is what folk music is all about: listening to other composers and players of traditional music and developing it in a way that suits your taste.So, let’s look at two citternists who can show you a bit about how this instrument is played. And yes, whilst famous is a push, these guys may well be considered rockstars in the world of the cittern.Ale Carr.Let’s start with Ale Carr, the cittern player with the Denmark-based band Dreamers’ Circus. These guys play awesome classical-inspired folk music, combining Carr’s cittern and a fiddle.Carr shows you what contemporary cittern-playing can be â€" and t he tunes he plays on his five-course (ten-string) cittern are really incredible.You can find some solo performances on YouTube. Otherwise, you can find him on the folk circuit across Europe and beyond.Gregory Doc Rossi.Meanwhile, Gregory Doc Rossi is something of the boss of traditional cittern music. As something of a specialist in the cittern, he has established the Cittern Society â€" an organisation that promotes cittern music â€" he has given lectures and research on the history of the cittern, and he has recorded music from forgotten manuscripts of scores for cittern.Regarded as something of an expert of the cittern, he performs all over the world on this string instrument.How to Play the Cittern.The cittern is traditionally plucked with the fingers â€" as opposed to the mandolin, for which a plectrum or a quill was traditionally used.However, these days, it is common to use a plectrum â€" as both Rossi and Carr do.Whilst anyone with knowledge of the classical or acoustic guit ar would be able to play a cittern, the primary â€" and not insubstantial â€" difference is in the cittern’s courses. This means that with every note that you fret, you are required to actually fret two strings simultaneously. Whilst this is a bit tough on the fingers at first, you will soon get used to it.On the other end of the instrument, however, you have to be able to pluck both strings simultaneously too. This is why the plectrum has become a bit more popular than fingerpicking on the cittern.Whilst picking, it is crucial that you engage both of the strings, otherwise your tone will be affected. If only one string sounds, you won’t get as much volume or as much depth of tone. Learn all of these amazing string instruments.How to Tune a Cittern?As citterns are traditional instruments, there is no single standard tuning that is used. Rather, there are as many as is convenient for you.We get that this does not provide a huge amount of guidance! However, many citternists use one of the following tunings:CGDADDGDADDADADIf you have a four-course cittern, traditional tunings areBGDEAGDEWhere to Find Cittern Lessons.A good teacher is always a gift when you are starting out on a new instrument.

A College Students Guide to Applying to Grad School

A College Student's Guide to Applying to Grad School For some college students, the eventual completion of their four-year degree signifies not a sigh of relief or an entry-level position with a company, but instead more school! For these individuals, applying to an advanced degree program contains its own unique set of challenges and expectations. If you are one of these students, here are three tips to help you along your path to graduate school. 1. Examine your decision to attend graduate school then examine it again Pursuing a graduate degree upon completion of your Bachelors is not an inherently poor choice. It is, however, a decision that can prompt a surprising number of negative reactions from family, friends, and professors. While the majority of these responses will ultimately be of little consequence to you, two are valid. First, does your intended field of study prefer its applicants to possess real world experience? Certain programs, such as business management and creative writing, feel professional expertise and time outside the college bubble can deepen the impact and success of their curricula. In some instances, this is a suggestionin others, a requirement. Second, are you prepared to devote an additional two to seven years to academia? Both a Masters and a Doctorate degree require intense devotion to a given subject. Do you have the necessary drive and focus immediately following four years of college? Or would a gap year do you well? You may also want to take a look at this information to determine if grad school is the right option for you. 2. Develop a schedule that balances your various graduate and undergraduate commitments If you are still confident in your decision to attend graduate school, congratulations! Young graduate students often lend enthusiasm and a uniqueness of perspective to their programs. Note, however, that the application process can be grueling. Organization and time management are imperative for success. Here are the best classes for grad school admissionsthat you may want to take a look at as well. Typically, graduate school applications are due late in the fall semester or at the start of the spring semester. If possible, schedule difficult undergraduate classes in the latter half of the yearor, if you decide upon graduate school as a junior, complete them then. Designate one or two days per week to create and polish your personal statement, resume, etc. Adhere to this arrangement. A graduate school is unlikely to accept you if your grades plummet as a result of your application preparation, so give equal focus to your undergraduate commitments to avoid this predicament. These are some great tips on how to write an application essay for grad school. 3. Establish and abide by important wellness measures It is very likely that your senior year of college will be a stressful one. For the majority of prospective graduate students, this potential reality is well worth weathering. Walking at graduation can be especially meaningful with an acceptance letter in hand, as well as the comfort of a clear future. To minimize the effects of stress, eat well and maintain a consistent sleep schedule. Do not allow yourself to work late into the night on an application or assignmentthe quality of your effort is liable to be poor, as a result. Instead, arrange meals with friends. Socializing is excellent for your state of mind. Reserve weekends or other periods of time for recreation you enjoy. See a film or sporting event, or visit a new city. And exercise often. Physical exertion sharpens your senses and relieves tension. Best of luck with your applications!
