Here are some safety practices which can help you avoid any untoward incident that can happen while you are operating your chemistry laboratory.Do not forget to clean the chemical area before you leave. Even if the work area is isolated from other areas, remember to clean it before leaving the lab. Chemical cleaners or steam cleaners should be kept at the door of the laboratory.Keep the light on when you leave the laboratory. The darkness can create a dangerous situation in the room. If there is a power cut in the room, turn the lights on. If the lights are switched off, other people might be outside your laboratory, so light can make them unsafe to enter the laboratory.After your laboratory is finished working, remove all the c hemicals from the chemical area. The chemical area is generally an area where the chemicals are stored. Do not store them in a closed container, in the same place where they are being used.Close all the doors to the chemical area, so no person can enter the laboratory. Make sure the door is locked tightly. There should be a sturdy lock for the laboratory. The locked door will prevent any entry into the chemical laboratory, while the chemicals are being used.Another one of the safety practice to follow is to label the closed containers when they are not being used. If it is not used for more than three days, label the container with the date when the container was emptied completely.These are just few safety practices of the chemist's safety which are recommended before leaving the laboratory. All those people working in the laboratory should follow these safety practices to ensure a safe lab environment. Keep the chemicals stored under lock and key, to avoid getting into any mishap or any injury in the laboratory.

6 Tips to Excel in Law School

6 Tips to Excel in Law School Success in law school is a daunting task. Unlike exams in most other post-graduate specialties, a law school final may account for almost 100% of your grade in many classes. So: how do you navigate the trials ahead and manage to excel in law school? 1. Consider law school a full-time job Act as you would at your place of employment. Do not forego class because you want to sleep in or because you are terrified of being called on. Keep to a specific schedule. Develop strong habits early on; set a clear plan for your day and follow it. Keep a calendar. Consider classes meetings and be productive in-between each period. Use the down time to work on your reading or other projects. Depending on the amount of class hours you have per day, keeping a nine-to-five schedule is not impossible, especially when supplemented with weekend review. 2. Locate outdated class outlines Find an old class outline early on, preferably as the semester starts. It is likely that the syllabus has changed somewhat from the year before. However, the value of locating an old outline is that it will aid in understanding the trajectory of the class. It can be difficult to understand the overall scope when each week of reading is confusing enough on its own. Law school professors also like to be elusive. Peruse the outline to determine what is ahead. Use that to re-frame professors questions. It is likely they are asking each question to drive you in the direction laid out in the next several classes. Usually, a decent outline will have notes from each class session, providing you with an idea of where you are and where you will be going. Do not rely too heavily on this tool, however. 3. Create your own notes and outline as the class progresses Although old outlines are useful for a broad overview, you should type up your own class and reading notes and organize them into an outline of your own each week. Do not wait until Thanksgiving (or later!) to create an outline for each class. Train yourself to build it as you go. That way, you will have plenty of time to edit it down as finals approach. Do not worry about the format do what works for you. You will have ample time to test your outline as you complete practice exams near the end of the term.Here are 3 note-taking formats every student should try. 4. Determine what your professor is interested in Read his or her resume. Investigate any law review articles or other research/opinion pieces they have written. Look for their most recent publications. Chances are, if your professor just spent a year of his or her life writing an in-depth analysis of a nuance in the law, that nuance will be on his or her mind and on your final. Try to identify what your professor is thinking so you have a better idea how to answer his or her questions on the exam. 5. Complete past exams Often, law schools will provide old exams to students. Ask your professor or TA if any past tests are available. Once you are nearing the conclusion of the class, begin to sit down and take the exams with your almost-completed outline. Observe the time limits and other restrictions the professor notes on the past exams. Then, compare each response to the model answer, or better yet, re-write them after carefully poring through your textbook and other resources (including your professors articles). It is an excellent study tool and takes some of the law school exam jitters away. Here is a test taking tip on how to review an exam before you take it. 6. Recognize when to stop Understand the law of diminishing returns. Eventually, the marginal return on an extra minute of studying is just not going to be worth it. Tired minds are not efficient tools. Know when to stop and sleep. If you have budgeted your time well, you will be able to pick up the slack the next day. Do not study all night, no matter how much you think it will help you excel. Force yourself to proceed at a manageable, constant rate, rather than blocking out eight hours of study time for one subject after you finish class that day. Here are some great test taking tips on the best study habitsthat you may find useful. The best advice to succeeding in law school is to remember that you are not alone. Do not be afraid to pose questions to fellow students, faculty, and support staff. If you are unsure how to read a case, ask a friend, go to the professors office hours, or work with a tutor. If you have a TA, ask them. Use the resources around you in order to excel!

Since Africa is famous for percussion in its music, the violin is in the minority with less than 3% of the population playing the instrument. African drums, and the djembe, in particular, are far more common.So how do you play the violin in Africa? What is special about the way the violin is played in African music?In this article, we’ll be looking at the history of the violin in Africa, the instruments related to the violin in Africa, and places in Africa where you can study music and playing the violin.

Most string instruments are either bowed or plucked and although the violin isn't widespread, there are plenty of similar instruments.There are a number of string instruments that, unlike the violin, are native to Africa. (Source: PilotBrent)Thus, it’s not uncommon to find instruments similar to the violin in African countries.In West Africa, yo u can find the riti, an instrument with just one string that creates a high-pitched sound with the bow.The N’goni from West Africa is halfway between a guitar and a violin.In Central Africa, the ennanga is a harp-shaped instrument with an oval soundbox.The guembri is popular in North Africa, especially amongst the Berber and Tuareg populations.In East Africa and Kenya, the orutu is very similar to the violin as it’s an old vielle.In Central Africa, the n’gombi is a mix between a harp and a violin.The kabosy, a guitar-shaped instrument, is popular in Madagascar.Did you know that over 400 different types of string instruments have been found in Africa?Instruments like the kundi and seto (Central Africa), the sintir (Guinea), and the krar (Subsaharan Africa) are also common. Most of these stringed instruments are used for folk music and local customs.What are the local customs associated with the violin and related instruments?The Violin and Stringed Instruments around AfricaAs w e said before, violin concerti aren’t widespread in Africa. Furthermore, the concepts of classical music, the symphony orchestra, and the string quartet are relatively new to the continent and the musical instrument itself doesn't really blend with local African music.North Africa, Where the Violin is KingThe violin arrived in the region around the 19th century and was quickly adopted into Arabic culture. However, the violin was played on the floor while standing up rather than with a shoulder rest and chinrest.The violin is played in different ways in different parts of the continent. (Source: PilotBrent)Did you know that there’s an agreement between Northern African countries called the Sol-Ré-Sol-Ré Accord?This allowed the violinist to sit down while playing and helped create the nouba. In the 20th and 21st centuries, this trend changed and North African violinists started adopting the traditional European posture with the violin under their chin using a chinrest and, in so me cases, a shoulder rest.As a result, North Africa is where you can find the most violin players in Africa.Original String Instruments in West AfricaThere are a lot of string instruments similar to the violin in West Africa. However, the violin isn’t very common. Some French-speaking countries, such as Senegal, play the violin in some music schools. However, percussion is far more common in local customs than string instruments. You're far more likely to hear traditional drums than the sound of violin strings.The Rest of AfricaIn general, Africa is a continent of percussionists with many different types of drums used in traditional music.With the exception of South Africa, there aren’t a huge number of establishments offering violin tuition. After all, symphony orchestras and orchestral music don’t really work well with traditional African repertoire.Where Can You Learn to Play the Violin in Africa?African musical culture is folkloric and passed down from generation to genera tion either through family members or village musicians. As a result of this musical culture, there are very few musical establishments and even fewer that offer violin tuition. As we said before, you’re more likely to find violins in North Africa, where it’s more commonly played.The violin never really made it across the Sahara. (Source: hassan9)However, there are a few places you can learn to play the violin:National Institute Supérieur De Musique, Casbah, AlgeriaConservatoire National De Musique Et De Danse, Rabat, Agadir, or Tetouan, MoroccoMusic School of Eastern Africa, Kisumu, KenyaNational Center Musique Des Arts Populaires, Tunis, TunisiaCairo Conservatoire, EgyptThere are also private establishments and schools where you can learn to play the violin in Africa:Dakar Music School, SenegalYared School of Music, EthiopiaThe Music Fund provides music education in Brazzaville, the Democratic Republic of the CongoSouth African College of Music, South AfricaThese are places w here you can learn music theory, how to hold the instrument and work on classical violin techniques and local violin techniques. Each ethnicity has its own instruments, sounds, and musical culture. You can also learn about the different instrument families, how to read violin sheet music and ancient violin techniques. Sometimes you can get specialised education with a focus on the cultural aspects of the instrument.Generally speaking, there are very few establishments offering higher education and violin tuition on the continent and less than 10% of Yehudi Menuhin International Competition for Young Violinists entrants are African.That said, that doesn’t mean there aren’t any famous African violinists.Famous African ViolinistsWhile European violinists like Vivaldi, Beethoven, and Mozart are the first people mention, there’s also a massive musical heritage in Africa. Just like the greats, they played chamber music and were given violin lessons during their youth. There are chil d prodigies and musicians passionate about string instruments just as you would find anywhere else in the world.Despite not being that popular in Africa, there are a lot of talented African violinists. (Source: Joe-Laming)Joseph Antonio Emidy. Born in 1775, this African violinist was a slave before he became famous in the UK. His compositions are part of the UNESCO Emidy Project.Adama Dembélé. This famous violinist was born in Burkina Faso. His family were wordsmiths and raconteurs, a common vocation in African culture. He played the sokou, a traditional stringed instrument.Monia Rizkallah. This Moroccan musician quickly developed a passion for the violin and she now plays in symphonic orchestras all over the world. While she doesn’t often return to Morocco, she has performed concerts there.Jasser Haj Youssef. As one of the only violinists to play the viola d’amore, he’s one of the greatest violinists of his time. Originally from Tunisia, he attended a conservatoire from the age of 8 and was well-versed in all the subtleties of a symphonic violin. He’s now a composer and performer.Issa Mbaye Diarry Sow. While famous across Europe but not in his native country of Senegal, this violinist has had a wonderful career.Abdo Dagher. This Egyptian virtuoso is thought of as a living legend by many. Born in 1936, he’s played in several Arab orchestras, including Umm Kalthumm.Kyla-Rose Smith. This young South African violinist was born in 1982 and was classically trained in the violin. She played the violin alongside Shakira for the World Cup.Are you interested in playing the violin?As one of the noblest instruments to exist, the violin perfectly complements local and authentic techniques. Of course, you won't be studying baroque music as you would in Europe.If you can't travel to Africa, don't forget there are private tutors available in the UK such as the tutors on Superprof. Since you're a tutor's only student (in that class), they can tailor all the lesson to you.Additionally, a large portion of the tutors on Superprof offer the first hour of tuition for free. This is a great opportunity to talk to them about how they teach, what a violin teacher can bring you, and just to see if you get along. Whether you want to learn the violin for fun, get into a prestigious music school (in Africa or elsewhere in the world), or become a professional violinist, you can find a tutor to help you work towards your goals.For those who live rurally or have a work schedule that doesn't allow them to get regular violin tutorials, there are always online private tutorials via webcam. These are often cheaper than face-to-face tutorials as the tutor doesn't have to cover the cost of travelling in their rates.Violin is played differently around the world, learn more about how the violin is played in America or how violinists  play in Asia  and the importance of the violin in Europe.

Estrangeirismos e influência

Estrangeirismos e influência artur84 / FreeDigitalPhotos.netEmbora seja parte da nossa cultura dublar filmes e séries em Inglês, somos muito dados aos estrangeirismos, que são aquelas palavras em Inglês, que são de uso tão corriqueiro, que acabam sendo adotadas por nós. Alguns exemplos são dizer que determinado local é o point ou spot de encontro da galera, comentar que o look de alguém é fashion ou simplesmente dizer ok como forma de concordar com algo.Estes estrangeirismos são muito comuns e, de certa forma, ajudam a que mais pessoas tenham contato com o Inglês. Contudo, é preciso que estejamos conscientes de que, especialmente, em ambientes profissionais, a utilização de tais expressões pode ser prejudicial.Porém, se por um lado é sensato evitar estrangeirismos, por outro somos obrigados a usá-los, porque estes se estabeleceram como a forma mais usual (e por isso mais compreensível) de dizer alguma coisa. Algumas palavras como site, mouse, online, offline, e-mail, designer, blog e deliver y são exemplos disso.Vale lembrar que existem ainda palavras que começaram como meras adoções literais, como os exemplos acima, mas que ganharam grafia própria quando passaram a figurar nos nossos dicionários, como é o caso de stress que se transformou em estresse e deu origem às variações estressar, estressante,  estressado.Também existem siglas, que muitas pessoas nem sequer sabem o que querem dizer, porque são derivadas do nome da coisa em Inglês, tornando mais complexo o seu entendimento em Português. Quando me mudei para Portugal levei um choque cultural tremendo no que diz respeito a isso, porque enquanto no  Brasil a gente diz AIDS (Acquired Immunodeficiency Syndrome), DNA (Deoxyribonucleic Acid) e HIV (Human Immunodeficiency Virus), lá as pessoas dizem SIDA (Síndrome da Imunodficiência Adquirida), ADN (Ácido Desoxirribonucleico) e VIH (Vírus da Imunodeficiência Humana). Contudo, as nossas placas de sinalização dizem PARE, mas em Portugal dizem STOP.Para mim foi engraçado ver essa diferença entre dois países de lingua portuguesa, mas acho ainda mais interessante ver como algumas palavras em Inglês se infiltram no nosso idioma, seja com sotaque português ou brasileiro, fazendo com que tenhamos que nos habituar a elas.A verdade é que a língua é um organismo vivo, que tem que adaptar para acompanhar o desenvolvimento social, cultural e tecnológico dos seus falantes. Por isso acaba sendo inevitável o uso dos estrangeirismos, mesmo que os países lusófonos muitas vezes impulsionem a evolução de formas diferentes o que aumenta ainda mais a distência linguística entre eles -, tal como acontece no caso das siglas ou como acontece com a palavra stress (grafia em Inglês), que no Brasil se escreve estresse e em Portugal stresse.

English Prepositions and the Worlds Largest Graffiti Tag

English Prepositions and the Worlds Largest Graffiti Tag The correct use of the English prepositions on, at and in can be difficult to remember. With this lesson, were going to look at it with an interesting story about a piece of interesting graffiti. First heres a little grammar to help you out.[table id=1 /]Below, youll find on, at and in highlighted when used as prepositions.If you go to New York City and see what is probably the worlds largest work of graffiti, you probably wouldnt think much of it. In fact, youd most likely think it was quite small.It is, from one perspective, not much wider than a line a pencil might make. Just a thin orange line on the streets and sidewalks of New York City that starts at the edge of a West Side pier and ends after crossing a footbridge at Franklin D. Roosevelt Drive.But if you were to follow this line around the city, and trace it on a map, youd find that it spells Momo, the name of a prominent New York City graffiti artist.How Momos tag looks on a map.Below youll find a description of this graffi ti tag as it appeared in an article by the New York Times.The project was inspired by a series of purple footprints that were painted on Manhattan sidewalks in 1986, stretching from the Upper East Side to Foley Square. Those mysterious markings led to a spot on Eldridge Street on the Lower East Side, where the city had bulldozed an elaborate community garden called the Garden of Eden that was created by a squatter named Adam Purple. Momo said he glimpsed the footprints as a child and was captivated.“It was a really ephemeral, strange sight,” he said. “And it felt like those footprints created a path that was all mine.”Years later he experimented for months with a way to make his own paint trail and eventually lashed a homemade funnel-shaped bucket to the back of a bicycle. He fitted the bucket with a hose that was controlled by a ball valve of the sort used in swimming pool plumbing systems. The line was created with 15 gallons of paint dispensed over the course of two covert sorties, Momo said, carried out between 3 and 6 in the morning.“Everyone was oblivious except for one guy who chased me,” he said. “But I think he was trying to be helpful, believing I was heading to a job site and had a legitimate leak.”In many neighborhoods the paint is still easy to see. Sometimes the line runs on concrete sidewalks, as it does along Stanton Street or Broadway. At other times it runs on macadam roadways, as it does on Seventh Avenue South, where the tires of countless cars have nearly erased it. In certain areas â€" along Prince Street, for instance â€" the line can no longer be seen at all, scrubbed away, maybe, or lost when sections of sidewalk were replaced.Momo made this giant graffiti tag using his bicycle, and a funnel that he set up to continuously drip paint as he rode. He made the tag in two early-morning bike rides. Below youll find a short video made by the artist that shows his graffiti tag. Thanks for reading!
