Advanced longboarders may be seen "sliding" (skidding sideways) to slow their boards on really steep hills. Special gloves incorporating a hockey-puck-like friction pad velcroed to the palm may be worn, which assists in both balance and braking, allowing one hand to be dragged on the ground. A lot of longbarders just make their own gloves, from sections of sliced-up cutting board epoxied to the palm and fingers of work gloves. On narrow, terribly steep hills (such as in San Francisco, for example), there's not enough room to carve back and forth to keep one's speed down, and "bombing" (dashing downhill) similarly could result in an accident or uncontrollably high speed, and so sliding was invented by a California surfer. sliding is a difficult and advanced method of slowing a board, though. While learning the slide, full pads and a helmet are a must. During more ordinary city commuting, the easiest (and first) braking skill one learns is simply to drag the toe or heel of one's rear foot on the ground. The trucks (swivelling axles) of a longboard turn far more freely than that of a freestyle board.
One good way to learn how to ride a longboard is to find a roomy, smooth flat area, a plaza or parking lot, say, and to just cruise around. Once the longboarder is feeling good and loose, warmed-up, then he should take that rear foot been pushing with, and try coasting without placing it back on the rear of the deck. Just coast, and notice how he actually can steer the board with one foot. Notice, too, that one can go much faster if one keeps his body's weight balanced above the foot that remains on the board. By pumping with the arms and pushing only with the ball of the driving foot, one go much faster (and prevent ankle injuries). If one finds himself slamming his driving foot down on the pavement, he will probably be in need of a rest. Now he is ready to carve. Carving is an action in which the rider leans back and forth slowing them down.
most longboarders go down mountains and hills. unlike skateboarding, longboarding aren't to good for tricks all though one can still do them.
Graffiti is marks, scratching or drawings made on a surface on a public place. It is often created with paint or spray paint (paint that is sprayed from a can). A single mark could be called a graffito but the word graffiti is usually used, meaning that there is more than 1 mark.
Graffiti can take the form of art, drawings or words. When done without a property owner's permission it is considered vandalism. Sometimes it is just a person's name or a rude word. Sometimes it is a public political protest because Graffiti is illegal without permission.
Graffiti has been found in very old cities. For example, in the Roman Empire, people wrote messages and drew caricatures on walls. Graffiti is also found in many places. Some people do murals of graffiti rather than just writing one mark in a location. It was used for good instead of vandalism. Probably the simplest graffiti is when a person cuts (or carves) the name of a lover on a tree with a knife.
Today, many graffiti are very complicated mixtures of writing and pictures. They are sometimes made by gangs and applied with spray-paint to buildings, bridges, street signs, and other areas. These are often signed with a "tag" (in graffiti slang, a signature), which is a shape special.
Graffiti can be thought of as a part of hip hop or street protest. It is often but not always illegal. Some cities have small areas where graffiti can be made. Sometimes graffiti are very beautiful. Some people consider graffiti as not only something bad, but something good, like art. Some people pay graffiti artists to do graffiti on their buildings. In the 1980s, some graffiti artists like Keith Haring became very famous.
Modern graffiti was made famous in New York City in the early 1970s by the children of the working class. They called it "writing," and called themselves "writers." In a 1971 New York Times article, the term "graffiti" was first used to refer to the new urban art explosion that was becoming popular in New York City. This period of the early 1970s is known as the "Original School." Later in the 1980s, the next generation of graffiti artists is known as "Old School."
Appellation d'origine contrôlée
Appellation d'origine controlée (AOC, "controlled designation of origin") is a French phrase which shows that a product comes from a certain area.
Some products must come from a certain area and be made in a certain way in order to have the name of the product. The most famous example is champagne, which must be fermented in the bottle and be made in the Champagne region of France.
The French government set up the "Institut national des appellations d'origine et de la qualité" (INAO, "National institute of controlled designation of origin") in 1935 to oversee the system. Although usually linked with wines, the start of the system of protecting the name of goods started in the 15th century when the French parliament defined what could be called Roquefort cheese.
AOCs are most often found in connection with:
Distillation is a process where a mixture made of two or more liquids (called "components") with different boiling points can be separated from each other. The mixture is heated until one of the components boils (turns to a vapor). The vapor is then fed into a condenser, which cools the vapor and changes it back into a liquid that is called "distillate". What remains in the original container is called the "residue". This is a physical separation process and not a chemical reaction. Fractional distillation (using a distillation column with more than two outlets) can be used to improve the separation. An oil refinery uses fractional distillation to purify crude oil, separating several different liquids for different uses.
This has been used for a long time, to distill alcohol and produce alcoholic drinks. Distillation is a commonly used operation in many industries.
Distillation can be done anywhere, whether it's in a house or a laboratory, but in most countries it is illegal to distill alcohol without a license. Illegally distilled alcoholic drinks are in some places called "moonshine".
Distillation is also the main way of desalination of water. In this case the salt is a solid that is in solution with the water. In alcohol distillation or petroleum distillation, the things to be separated from their solution are two or more distillation liquids.
A lawyer (also called an "advocate", "attorney", "barrister", "counsel", "counsellor", or "solicitor") is someone who practices law. A lawyer has earned a degree in law, and has a license to practice law in a particular area.
If people have any problem regarding the law, they can contact a lawyer for advice. A legal problem is referred to as a case. A person can hire a lawyer to start a case against someone else, or to help with a case that has been started against them. If the case goes to court, the lawyer will represent their client in court. The lawyer will use their knowledge of the law to convince the court that the client is on the right side of the argument. Lawyers also help people "settle out of court," which means that both sides of the argument agree to resolve the dispute ahead of time so that they will not have to go to trial.
When a person is accused of a crime, the person has a defense lawyer to try to show they have not committed a crime. The lawyer arguing that they did do the crime is called the "prosecutor".
Lawyers also prepare legal documents for their clients. Examples: buying or selling property or making a will (testament). Certain lawyers (called "commissioners of oaths" in England) can take legally binding witness statements which can be presented to the court.
Lawyers work in different settings. Some work by themselves, while some work in law firms. Some lawyers work for hospitals and private companies. Lawyers who work for private companies are usually called in-house counsel.
Lawyers generally charge a fee for the work that they do, but sometimes advice is offered freely, which is called "pro bono," meaning "for the public good." In many countries, if a person is accused of a crime and unable to pay for a lawyer, the government will pay a lawyer to represent them using tax money.

Loreto Region
Loreto is Peru's most northern region. Covering almost one-third of Peru's territory, Loreto is the nation's biggest region. It is also one of the least populated ones, because of its remote location in the Amazon rainforest. Its capital is the city of Iquitos.
The region is divided into eight provinces ("provincias", singular: "provincia"), which are composed of 53 districts ("distritos", singular: "distrito"). The provinces, with their capitals in parenthesis, are:
Iquitos is the capital city of the Loreto Region in northern Peru. It is on the banks of the Amazon River. Iquitos is the biggest city in the rain forest of Peru, with about 400,000 residents. It is a major port on the Amazon.
Excluding towns on islands, Iquitos is thought to be the largest city in the world that can not be reached by road. One can only get to Iquitos by boat, or by airplane. It is very remote, in the middle of the Amazon rainforest.
Iquitos was founded in 1747 by Jesuit José Bahamonde. Originally it was the home of the Iquito native tribe. About 100 years ago, Iquitos was a very rich town, because of the rubber industry. Today Iquitos relies mostly on tourism, wood industry and local trade.
Apple juice
Apple juice is the juice from apples. It does not have alcohol, and it tastes sweet from the natural fruit sugars. Many companies making apple juice like to say that they do not add more sugar into the drink, and there is only natural sugar.
The apple tree came from the same era as Elizabethan in the late 1500s and early 1600s ("Pyrus malus"), and is native to Britain. Even in the Old Saxon papers, apples and cider are mentioned a lot. The fruit is thought to have come in the Caucasus, a place with many mountains between the Black and Caspian Seas.
The Lady apple, a kind of apple still grown today, is believed to be one of the oldest apple trees on record.
Apple juice is 88% water and 11% carbohydrates (including 9% sugars), with little amounts of protein or fat.
In both facts and stories, the apple appears to be very healthy. There are two types of apple juice. One is the clear apple juice, and the other is the cloudy apple juice. Pectin and starch are taken out during the production process to produce clear apple juice. Cloudy apple juice is cloudy because of evenly-distributed small pulp suspensions in the juice concentrate.
Also, in apple juice, the vitamin C, and other vitamins are contained inside, as well as mineral nutrients such as boron which helps build strong bones.
Apples can also be a main source of fiber, and is a powerful cleanser and an important necessity for the health of your body.
The compounds in apple juice called phytonutrients delay the break down of LDL or cholesterol. In history, the phrase from Benjamin Franklin "an apple a day keeps the doctor away" is very famous. New research is proving this phrase to be a fact. Researchers at UC Davis School of Medicine have recently found out that drinking apple juice seems to slow down the process that may lead to heart disease.
Researchers at the University of Groningen in the Netherlands had studied and found that smokers who ate many fruits and vegetables, especially apples, had reduced their risk of getting the common diseases smokers would get. The risk was reduced by 50%.
For older people, drinking fruit juices should begin with apples, especially if they are suffering from arthritis and rheumatism. This is because apples carry a substantial amount of potassium. Because of this, eating apples or apple juice has been known to help. Drinking apple juice also removes some toxins from the liver and kidneys and is low in calories. Over time, this can reduce the chances of having liver or kidney disease.
Apple juice can be used to make cider and calvados. Some types of cider and all types of Calvados contain alcohol.
Addressed as one of the most popular fruits in the world, the apple is cultivated in around 7,500 different kinds in shape, color, texture, firmness, crispness, acidity, juiciness, sweetness, nutrition, and harvesting time.
Fresh apple juice needs refrigeration. Closed bottles of canned apple juice can be kept in a dark, cool place, such as a pantry or cupboard. It slows down the spoiling of the product. The way it looks, feels, or tastes could change over time.
Once the juice container is opened. Or if it was not closed and shipped without needing freezing by the producer, it must be closed again tightly and frozen to avoid contamination from microorganisms such as bacteria.
Calvados (drink)
Calvados is an alcoholic drink. It is made from distilling cider in Normandy, one of the oldest Provinces of France (created in 911). It got its name from the place called Calvados which is famous for making it (sometimes called 'le Pays d'Auge'). It is also made in the other places in Normandy including la Manche (Cotentin) and l'Orne (Domfront).
The way to make Calvados is to distil cider twice. The first time it is done, the result is a liquid containing 28% to 30% alcohol. The second time it is done, the amount of alcohol is increased to about 40%.
Since 1942, the Calvados has its own "Appellation d'Origine Contrôlée (AOC)", which means it is from one place. The rules are:
Calvados can be served either dry or with ice, as a cocktail, an aperitif, or as a digestif. It goes very well with cheese, chocolate, dessert or ice cream. Crepes can also be served with Calvados.
Calvados can also be added to coffee. People usually do this at the end of dinner.
A still is a tool used to clean a liquid. It does this by first boiling the liquid and turning it into a gas. This gas is then cooled, changing it back into liquid. Stills get their name from the word di"still"ation. Distillation is the process of boiling and cooling a liquid to purify it. Stills are most often used to create alcohol, but they can also be used with any liquid. Some examples are medicines and perfumes.
There are two main types of stills: pot stills and reflux stills. In a pot still, the pot (like a large kettle) holding the liquid is heated. The hot gas is cooled in a simple neck, or tube, and collected. Pot stills are used for making alcohol like whisky. A reflux still is much more complex. It works with a continual flow of liquid going into the boiler, and a continual flow of distilled liquid coming out. The distilled liquid can also be put through the process several times, which is why it is called a reflux still. This allows for a more pure product, and the person working the still can control the level of purity. Reflux stills are used in the chemical and petroleum industries.
The Bridge on the River Kwai is a British 1957 movie from Columbia Pictures, based on Pierre Boulle's 1952 book "The Bridge over the River Kwai" (). The movie was mainly filmed in Ceylon (now Sri Lanka) and also in England.
In 1941 the Japanese Army invaded Thailand. They built a railway to link Bangkok to Rangoon. Thousands of Asian workers and POWs (prisoners of war) died while working on the project. Part of this project was building bridges over Thailand's Kwai Yai, at a place named Tamarkan, which is near a town named Kanchanaburi.
The deaths of the Asian workers and the prisoners were real events, but most of the book and the movie are not true. The British soldiers were slaves; they did not help the Japanese. Two bridges were built; one was made of wood, one was made of concrete and steel. Both bridges stood for two years and were destroyed by bombers in 1945.
In the movie the bridge is destroyed by commandos. A real train rode over the bridge as it blew up. (This can be compared to a scene in the 1927 movie, "The General", which starred Buster Keaton.)
The movie is best known for the "Colonel Bogey March", the song that is whistled by the POWs. It is also known as the "River Kwai March".
The movie won seven Academy Awards, one for Best Picture. It also won the BAFTA Award for Best British Screenplay.
Tannin
Tannins are bitter-tasting chemical compounds that bind proteins.
Tannins are present in the following:
Tannins are also used in the treatment of leather, to make it more durable. Natural tannins for this purpose come from oak trees, but synthetic tannins are more used.
Cuisine refers to any style of cooking, including its practices, traditions and recipes. A cuisine is usually associated with a specific culture. It is mainly influenced by the ingredients that are available to that culture. Cooking methods, customs and ingredients together form meals that are unique to a particular region. When people talk about Italian cuisine, they are referring to the food that Italians are famous for. Cuisine is a French word that means "kitchen", but it originally comes from the Latin word "coquere", which means "to cook".
Traditionally, cuisines are shaped by a number of things. In some religious traditions, certain foods are forbidden by law (an example is in Judaism). Climate and trade affect the what ingredients are available. Climate may also affect the methods by which food is prepared. Before the exploration of Asia and America by Europeans, certain foods were not known to European cuisine. Tomatoes, maize, avocados and cacao, for example, did not enter European diets until merchants brought these ingredients back from the New World. In modern times, cuisines are becoming more and more multicultural. New cuisines continue to develop even today.
A hotel or a guest-house is a large building with many rooms, where people can sleep when they are not at home. A motel is a hotel especially for motorists - people who drive cars - where the room door usually opens into the parking lot. Inn is sometimes used to mean a smaller hotel.
These places will rent a room for any number of days. They offer rooms to sleep, and want money for the service. There are also hotels where conferences are held.
Yale University is a private university in New Haven, Connecticut. It is in the Ivy League and considered by many people to be one of the best universities in the world. Yale is the third oldest university in the United States.
Yale was founded in 1701 in a town near New Haven by a group of church ministers. At first it was called "The Collegiate School" and was created to teach male church ministers in Connecticut. When Elihu Yale, a businessman with the East India Company, gave the school money and books in 1718, the school changed its name to Yale College. It moved into the center of New Haven in the same year. About fifty years later, the school began to teach other subjects like science and history. As the school became more liberal, it became one of the first American schools where extracurricular student groups were created, especially singing groups, sports teams, and student publications like the Yale Daily News.
In the beginning, Yale only taught undergraduate students. Over time, it created graduate schools for medicine, nursing, environmental science, law, music, drama, business, and other professions. In 1869, Yale became the first school in the United States to offer a PhD. Because it had grown to have many types of schools, degrees, and courses, Yale changed its name to Yale University in 1887. The undergraduate college began to accept women as students in 1969.
Yale has one of the largest libraries in the United States, with 19 library buildings and over 15 million books. The school's main library building, Sterling Memorial Library, is built to look like a cathedral. The Beinecke Library has one of the world's largest collections of rare books and old manuscripts.
The school's campus is known for its Gothic Revival architecture, which was built to look like older English universities like Oxford and Cambridge. On its main campus, Yale has two art museums, a natural history museum, and many theaters. The university also has a golf course near campus and owns five forests in New England.
Fifty-two Nobel Prize winners have been students or professors at Yale, and five U.S. presidents have graduated from Yale, including George H. W. Bush, Bill Clinton, and George W. Bush. Other famous alumni include politicians Hilary Clinton and John Kerry, actors Meryl Streep and Edward Norton, inventors Eli Whitney and Samuel Morse, CNN anchors Fareed Zakaria and Anderson Cooper, FedEx founder Fred Smith and Pepsi CEO Indra Nooyi, and computer scientist Grace Hopper.
Yale's color is blue, and its mascot is a bulldog named "Handsome Dan." Its sports teams are called the Yale Bulldogs, and they play in the Ivy League.
Peter Salovey, a psychologist, is the current president of Yale.
Salzburg (Austro-Bavarian: "Soizbuag") is the capital and also a district of the Austrian state of Salzburg or Salzburgerland. The population is about 150,000 and is the 4th largest city of Austria.
Its most famous citizen was Wolfgang Amadeus Mozart. Another famous inhabitant of Salzburg was the physicist Christian Doppler who found the Doppler effect which was named after him.
The Salzach river crosses the city. The old town was adopted by the UNESCO as World Heritage Site in 1996. Known is Salzburg also for being one of the settings for the movie "The Sound of Music" which based on the musical by Richard Rodgers and Oscar Hammerstein.
People lived in Salzburg since the New Stone Age till present. The oldest finding in the city area is dated around 4500 B.C. From 15 B.C. onwards after the Roman occupation the city was called Iuvavum. The roman city was situated in today's old town around the Waagplatz. The city became an important place from the east to the province of Germania. The Romans left on the beginning of the barbarian migration around 500. Up to 696 only few can be said about the history. 696 the city was given to bishop Rupert by Duke Theodo II. of Bavaria.
Rupert was ordered by the Duke to bring Christianity to the east and southeast of his country. Rupert founded the monastery St. Peter and for women the monastery Nonnberg. 739 Salzburg became the seat of a bishop and 774 the first cathedral was built. 998 Salzburg became archbishopric ruling the whole Bavarian area.
In the Middle Ages Salzburg became wealthy by the trade with salt from the nearby Dürnberg in Hallein. Till the 14th century Salzburg became independent from Bavaria and was a state within the Holy Roman Empire. The citizens of Salzburg were under the command of the archbishop unlike other cities in the empire. In the baroque era the look of today's city was shaped. The cathedral was rebuilt in the baroque style. Most of the architects came from Italy. 1622 a university was founded. Due to the fact that it was a catholic state Protestants had a severe standing in Salzburg. Yet 1731 Protestants, who came not back to the catholic belief had do leave Salzburg within eight days.
In the early 19th century Napoleon Bonaparte promoted the Duchy of Salzburg, than later was a part of the Kingdom of Bavaria. Then, Salzburg was annexed by Austria, returned to Bavarian and divided between Bavaria and Austria. 1918 Salzburg became a federal state of the new Republic of Austria.
In 1938, Germany annexed Austria and Salzburg was a part of Germany. In 1945, when Austria was independent from Germany. It became a federal state again.
Urban districts ("Stadtteile"):
Salzburg is a World Heritage. There are some places of interest like:

Basque (Basque: ) is the language spoken by the Basque people in the Basque Country and its diaspora. Although most other Europeans speak Indo-European languages, Basque is a language isolate and is not related to them or to any other language in the world.
The ancestors of Basques are among the oldest residents of Europe, and their origins are unknown, as are the origins of the language. Many scholars have tried to link Basque to Etruscan, African languages, Caucasian languages and so on, but most see Basque as a language isolate.
A connection with the Iberian language has given some hope, but it is unclear whether similarities are caused by genetic relations or mere vicinity.
It was spoken long before the Romans brought Latin to the Iberian Peninsula.
Basque is spoken in an area that is smaller than what is known as the Basque Country (Basque: "Euskal Herria)". Basque was once spoken over a larger area, but Latin took over in some places.
Historically, Latin or a Romance language has been official.
Today Basque holds co-official language status in the Basque regions of Spain: the full autonomous community of the Basque Country and some parts of Navarre. Basque has no official standing in the Northern Basque area of France, and French citizens are barred from using Basque in a French court of law.
There are six main Basque dialects, comprising Biscayan, Guipuzcoan, and High Navarrese (in Spain), and Low Navarrese, Labourdin, and Souletin (in France). The dialect boundaries are not, however, congruent with political boundaries.
One of the first scientific studies of Basque dialects, in particular the auxiliary verb forms, was made by Louis-Lucien Bonaparte (a nephew of Napoleon Bonaparte).
There is now a unified version called Batua ("unified" in Basque), which is the language taught in schools. Batua is based largely on the Gipuzkoa regional dialect.
Basque is an ergative-absolutive language. Its grammar is very complex, with many different cases for nouns.
The vowel system is the same as most Spanish-speakers and has five pure vowels, .
By contact with nearby peoples, Basque has borrowed words from Latin, Spanish, French, Gascon and others but accepted fewer than Indo-European languages. Some claim that many of its words come from Latin, but phonetic evolution has made many of them now appear as if they were native words, e.g. "lore" ("flower", from "florem"), "errota" ("mill", from "rotam", "[mill] wheel"), "gela" ("room", from "cellam").
Basque is written with the Latin alphabet. The universal special letter is "ñ", which is pronounced like the "n" in "onion", and "ç" and "ü" are also used. Basque does not use "c, q, v, w, y" except for loanwords and are not considered part of the alphabet. Also, "x" is pronounced as a "sh", as in "shine".

Chlorine
Chlorine (chemical symbol Cl) is a chemical element. Its atomic number (which is the number of protons in it) is 17, and its atomic mass is 35.45. It is part of the 7th column (halogens) on the periodic table of elements.
Chlorine is a very irritating and greenish-yellow gas. It has a strong smell like bleach. It is toxic. It can be made into a liquid when cooled. It is heavier than air.
Chlorine is highly reactive. It is more reactive than bromine but less reactive than fluorine. It reacts with most things to make chlorides. It can even burn things instead of oxygen. It dissolves in water to make a mixture of hypochlorous acid and hydrochloric acid. The more acidic it is, the more chlorine is made; the more basic it is, the more hypochlorous acid (normally turned into hypochlorite) and hydrochloric acid (normally turned into chlorides) are there. Chlorine reacts with bromides and iodides to make bromine and iodine.
Chlorine exists in several oxidation states: -1, +1, +3, +4, +5, and +7. The -1 state is most often in chloride. Chlorides are not reactive. Compounds containing chlorine in its +1 oxidation state are hypochlorites. Only one is common. They are a strong oxidizing agent, as are all + oxidation state compounds. +3 is in chlorites. +4 is in chlorine dioxide, a common chlorine compound that is not a chloride. +5 is in chlorates. +7 is in perchlorates. Hypochlorites are most reactive, while perchlorates are the least reactive.
Many organic compounds have chlorine in them. Freon has chlorine in it. PVC (poly-vinyl chloride), a common plastic, has chlorine in it.
Chlorine oxides can be made, but most of them are very reactive and unstable.
Chlorine is not found as an element. Sodium chloride is the most common chlorine ore. It is in the ocean (sea salt) and in the ground (rock salt). There are some organic compounds that have chlorine in them, too.
It is made by electrolysis (the passing of electricity through a solution to make chemical reactions happen) of sodium chloride. This is known as the chloralkali process. It can also be made by reacting hydrogen chloride with oxygen and a catalyst. It can be made in the laboratory by reacting manganese dioxide with hydrochloric acid. It is made when sodium hypochlorite reacts with hydrochloric acid. This is a dangerous reaction that can happen without anyone knowing.
As of 2021, the main use of chlorine is for bleach. It is also added to water, as a way of purifying it. Chlorine is both very reactive, and very poisonous. It will act as a disinfectant: if it is added to water, it will kill off bacteria and other organisms. Swimming pools are often filled with water that has been treated that way.
Germany used chlorine as a chemical weapon in the First World War. They used it at the Second Battle of Ypres in 1915. According to soldiers, which were present at the battle, the chlorine smelled like a mixture of pepper and pineapple. It also tasted metallic and stung the back of the throat and chest. Chlorine reacts with water in the mucosa of the lungs to form hydrochloric acid. Hydrochloric acid will destroy living tissue. It often kills. Gas masks with activated charcoal or other filters can protect the respiratory system. This makes chlorine gas much less deadly than other chemical weapons. German scientist Fritz Haber of the Kaiser Wilhelm Institute in Berlin was the first to use it. Together with IG Farben, he developed methods of how to use chlorine gas against an entrenched enemy. Chlorine is heavier than air, so it will stay in the trenches. On 22nd April, 1915, German forces attacked the French army. With of chlorine, they only killed about 1.200 French soldiers. For this reason, chlorine was soon replaced with the more deadly phosgene and mustard gas.
Because it is easily available, chlorine is still used as a chemical weapon in war. That way, it has been used in the Syrian civil war. It has also been used in an improvised explosive device in Iraq, in 2015.
Chlorine is used to make many compounds that are important: both chloroform and carbon tetrachloride contain chlorine.
It was discovered in 1774 by Carl Wilhelm Scheele who thought it had oxygen in it. Chlorine was named in 1810 by Humphry Davy who insisted it was an element. The US made all water chlorinated (added chlorine to water) by 1918.
It is poisonous in large amounts and can damage skin. When it is inhaled (breathed in), it irritates the lungs, eyes, and skin badly. It can cause fire with some things because it is very reactive. It is heavier than air, so it can fill up enclosed spaces.
The halogens are chemical elements under the second-to-right column in the periodic table, also known as Group 17. The elements in the group are fluorine, chlorine, bromine, iodine, astatine, and tennessine. Halogen literally means "salt becomer", but it is often cited to mean "salt producer". They are very reactive, so they are likely to join with other elements on the left side of the periodic table to make compounds. This is due to the fact that they are missing one electron. They are rarely found alone in nature. Fluorine is the most reactive, while iodine is the least reactive. Astatine is very radioactive and hard to get.
A vitamin is a chemical compound that is needed in small amounts for the human body to work correctly. They include Vitamin A, many B vitamins (like B, B, B, B, and B), Vitamin C, Vitamin D, Vitamin E, and Vitamin K. For example, citrus fruits such as oranges and lemons contain vitamin C.
The term was coined in 1912 by biochemist Casimir Funk, who isolated a complex of micronutrients and proposed the complex be named "vitamine". By convention the word "vitamin" does not include other essential nutrients, such as certain minerals, essential fatty acids and essential amino acids.
Thirteen vitamins are recognized at present. Vitamins are classified by their biological and chemical activity, and not their structure. Each vitamin name (the word "vitamin" followed by a letter) refers to a number of vitamer compounds which all show the same biological activity. For example, "vitamin A" refers to several different chemicals. Vitamers convert to the active form of the vitamin in the body. They are sometimes inter-convertible to one another as well.
The body does not make these chemicals. They come from other places, usually food. A short term lack of a certain vitamin is usually not a problem, because the body can store vitamins for a short time. Not having a certain vitamin for a longer period of time can lead to different diseases, depending on the vitamin. Probably the best-known of these diseases is scurvy, which results from not having enough Vitamin C. Beriberi and rickets are others.
Today, many drug companies make inexpensive pills that contain various vitamins. They help people avoid those diseases.
Vitamins can be either fat-soluble or water-soluble. Fat-soluble vitamins (A, D, E and K) can be stored in the body, and are used when needed. Water-soluble ones only stay in the body a short time.
Currently there are no vitamins F to J. These existed at some time. Today they are no longer seen as vitamins. Some of them were also false leads, and turned out to be something else. Others were renamed as B vitamins. Today, the B vitamins are a whole complex, and not just one vitamin.
The German-speaking scientists who isolated and described vitamin K (in addition to naming it as such) did so because the vitamin is intimately involved in the 'Koagulation' (clotting) of blood following wounding. At the time, most (but not all) of the letters from F through I were already designated, so the use of the letter K was considered quite reasonable.
The following table lists chemicals that had previously been classified as vitamins, as well as the earlier names of vitamins that later became part of the B-complex.
Adultery is a word used in religious texts like Exodus 20:14. It applies to a married person sleeping with someone other than the person who they are married to. Adultery usually comes with a heavy punishment for example, death by stoning in some Muslim countries. In most countries adultery is no longer a crime, but most people still see it as a bad thing.(see Gospel of John 8) If a person who is married takes part in adultery, that person's husband or wife would usually have the right to be able to go to court to divorce them.
The word adultery originates not from “adult”, as is commonly thought in English-speaking countries, but from the Late Latin word for “to alter, corrupt”: “adulterare”. “Adulterare” in turn is formed by the combination of “ad” (towards), and “alter” (other), together with the infinitive form “are” (making it a verb). Thus the meaning is literally “to make other”. In contrast, the word “adult” (meaning a person of mature years) comes from another Latin root, “adolescere”, meaning to grow up or mature: a combination of “ad” (towards), “alere” (to nourish, to grow), and the inchoative infix “sc”(meaning to enter into a state of).
Famous adulterers include :
Perjury is the word used for a person that tells a lie while they are under oath (in a courtroom). Committing perjury is against the law, and can be punished with a jail or prison sentence.
Perjury is a serious crime because it might be used to take away the power of a court, which can lead to punishment for the wrong person. In the United States, perjury is a federal offense, and it can be punished by five years in prison. However, in California, a person who commits perjury can get the death penalty if the perjury led to a wrongful execution.
The rules of perjury also apply when a person says or does something "under penalty of perjury", even if he or she never swore an oath. One example is the United States' income tax return, where people have to sign as true and correct under penalty of perjury. A person can be punished by three years in prison if he or she lies on the tax return.
A statement that involves "interpretation" are not perjury because people can judge incorrectly without knowing it. Perjury only happens if a person wanted to do it and then actually did.
The offence of perjury is written in section 132 of the Criminal Code. It is described by section 131, which says that perjury is when a person says something false when he or she knows that it is false. People who commit perjury can be imprisoned for fourteen years at most.
A person in the Court of Justice of the European Communities swears anything he knows is false is guilty of perjury. Proceedings for perjury can happen in any place in the State and the offence can be treated as if it happened in that place.
Perjury in American law comes from the common law of England, which defined the it as giving a false testimony under oath that has to do with the issue.
The American legal system defines perjury as saying anything knowingly false under oath to a "competent tribunal, officer, or person". The punishment can be a fine or up to five years in prison or both.
Lust is a term for a strong desire or wanting, or maybe even needing, often for sexual acts, although it is also commonly used to talk of a "lust for life" or a "lust for power" or for other goals.
As a sexual desire, it is considered a sin (a failing) by Christianity, which lists it as one of the seven deadly sins.
"Lust" was originally an Anglo-Saxon word which meant "desire" or "appetite".
Seven deadly sins
Some followers of Christianity say that there are sins that are the causes of all others. There are seven sins that they call "deadly". Although the Bible does not list the seven deadly sins, they are in the book The Divine Comedy.
Ranked in order (starting with the lightest and least evil) like in Dante's "Divine Comedy" (in the Purgatorio), the seven deadly sins are:
People see that some of these sins are connected. They have tried to put an order to them. For example, pride (love of self out of proportion) is needed for gluttony (the over-consumption or waste of food), as well as sloth, envy, and most of the others.
Each of these sins is a way of not loving God and not loving others as much as oneself. Scholasticism developed schema of attribute and substance of will to explain these sins.
As previously mentioned, the Latin words for the sins are: "superbia, avaritia, luxuria, invidia, gula, ira" and "accidia".
The first letters of these words form the medieval Latin word "saligia", whence the verb "saligiare" (to commit a deadly sin) is taken. Various mnemonic devices exist for remembering the sins in English, e.g. PEG'S LAW (pride, envy, gluttony, sloth, lust, avarice, wrath).
In the official Catechism of the Catholic Church, consisting of 2,865 numbered sections and first published in 1992 by order of Pope John Paul II, the seven deadly sins are dealt with in one paragraph. The principal codification of moral transgression for Christians continues to be the Ten Commandments and the Beatitudes, which are a positive statement of morality, and part of the Sermon on the Mount.
The opposite of these sins are the seven virtues (chastity, moderation, charity, zeal, meekness, generosity, and humility) in corresponding order to the above seven deadly sins.
According to the Divine Comedy, there are punishments for those who die with unconfessed deadly sins.
The Lustfuls, are in the second circle of the Inferno. There they are blown around by a strong wind, without the hope of ever resting. This is because lust is so powerful, that it can blow one around without need or aim.
The Gluttons are in the third circle. There, they are forced to lie in a kind of slush, made by freezing rain, black snow, and hail. This symbolizes what they made with their life.
The Greedy are in the fourth circle. There they are boiled in hot oil, it's the best oil that money can buy, but it's still pretty hot and you will be turned into gold.
The Slothful are in the fifth circle. There they are thrown into a snake pit where the indolent will have to move around to get the snakes off them eternally.
The Wrathful are in the fifth circle, as well. It is a combined circle of Sloth and Wrath. Their limbs are ripped apart, because the furious use their arms and/or legs in their act of violence.
Bromine
Bromine (Br) is a chemical element. Its atomic number (which is the number of protons in it) is 35, and its atomic weight is 80. It is part of the Group 7 elements (halogens) on the periodic table. It is diatomic, which means that two atoms are stuck together to make a molecule in any bromine sample.
Bromine is a red-brown liquid. Liquid elements are rare; only bromine and mercury are liquid at room temperature. It easily evaporates to make suffocating brown fumes. It has a bad smell. Its name means "stench of he-goats". It can become a metal at very high pressures.
It has two stable isotopes. They are Br and Br. There are about 29 other radioactive isotopes.
Bromine is quite reactive. Its reactivity is between chlorine, which is more reactive, and iodine, which is less reactive. It reacts with metals and nonmetals. Phosphorus reacts violently with bromine. Aluminum reacts in a similar way. It can bleach things like chlorine. It reacts better in the light. It dissolves a little in water. Hot water makes it disproportionate into hydrobromic acid and hypobromous acid. Bromine can form compounds with substances such as sodium to form sodium bromide.
Bromine forms compounds in many oxidation states: –1, +1, +3, +5, and (sometimes) +7. –1 is the most common. It is found as bromide. Bromides are not reactive. They are colorless solids that dissolve in water easily. Covalent bromides can be liquids or gases. The other compounds are all strong oxidizing agents. Their chlorine cousins are more common. +1 has the hypobromites, which are unstable. +3 has the bromites. Bromine dioxide is the only common bromine compound found in the +4 oxidation state. +5 has the bromates, which are more common than all the other ones except the bromides. Bromates are strong oxidizing agents and are sometimes added to flour. +7 has the perbromates. Perbromates are very unstable.
Bromine is found as bromide in the ocean and in brine pools. The Dead Sea has a lot of bromide in it. Bromine is not an important part of our body, unlike its relatives chlorine and iodine.
Bromine is made by bubbling chlorine gas through a solution of a bromide. The bromide is oxidized to bromine, while the chlorine is reduced to chloride.
It is mainly used to make organobromine compounds, organic compounds with bromine in them. Organobromines are used to put out fires. They used to be added to gasoline. Some were used as pesticides. Some inorganic bromides were used as sedatives. Bromine can also be used as a disinfectant. Silver bromide is used in film.
Bromine is toxic and corrosive to skin. Bromine gas is irritating when it is breathed in, too. Bromine can react violently with many things.
Fluorine
Fluorine (symbol F) is a chemical element that is very poisonous. Its atomic number (which is the number of protons in it) is 9, and its atomic mass is 19. It is part of the Group 7 (halogens) on the periodic table of elements.
Fluorine is a light yellow diatomic gas. It is very reactive gas, which exists as diatomic molecules. It is actually the most reactive element. Fluorine has a very high attraction for electrons, because it is missing one. This makes it the most powerful oxidizing agent. It can rip electrons from water (making oxygen) and ignite propane on contact. It does not need a spark. Metals can catch on fire when placed in a stream of fluorine. After it is reduced by reacting with other things, it forms the stable fluoride ion. Fluorine is very poisonous. Fluorine bonds very strongly with carbon. It can react with the unreactive noble gases. It explodes when mixed with hydrogen. The melting point of fluorine is -363.33°F (-219.62°C), the boiling point is -306.62°F (-188.12°C).
Chemical compounds containing fluorine ions are called fluorides. Fluorine only exists in one oxidation state: -1.
Fluorine is not found as an element on the earth; it is much too reactive. Several fluorides are found in the earth, though. When calcium phosphate is reacted with sulfuric acid to make phosphoric acid, some hydrofluoric acid is produced. Also, fluorite can be reacted with sulfuric acid to make hydrofluoric acid. Fluorite naturally occurs on the earths' crust in rocks, coal and clay.
Fluorine is normally made by electrolysis. Hydrogen fluoride is dissolved in potassium fluoride. This mixture is melted and an electric current is passed through it. This is electrolysis. Hydrogen is produced at one side and fluorine at the other side. If the sides are not separated, the cell may explode.
Someone made fluorine in 1986 without using electrolysis. They produced manganese(IV) fluoride by using various chemical compounds, which released fluorine gas.
Fluorine is used to enrich uranium for nuclear weapons. It is also used to make sulfur hexafluoride. Sulfur hexafluoride is used to propel stuff out of an aerosol can. It is also used to make integrated circuits. Fluorine compounds have many uses. Fluoride ions are in fluorine compounds. Fluoride ions can be in toothpaste. Some are used in nonstick coatings. Freons contain fluorine.
Fluorine as an element is extremely reactive and toxic. It can react with almost everything, even glass. Fluorine is also poisonous.
Fluoride ions are somewhat toxic. If too much toothpaste containing fluoride is eaten then fluoride poisoning may occur. Fluoride is not reactive, though.
Iodine is a chemical element. Its atomic number (which is the number of protons in it) is 53, and its atomic mass (the number of protons plus neutrons) is 127. It is part of the Group 7 (halogens) on the periodic table of elements and its electronic configuration is 2,8,8,18,17. It is a nonmetal.
Iodine is a dark purple-black solid. It is also a nonmetal and a halogen. It sublimes when heated to make a bright purple vapor. This vapor is very irritating, although colorful. Iodine does not dissolve in water, but it does dissolve in a solution of an iodide in water. It dissolves easily in organic solvents.
Iodine is at the bottom of the halogens and is the least reactive of the halogens. Iodine is an oxidizing agent, though not as strong as bromine or chlorine. It can become the colorless iodide ion if another atom or molecule gives an iodine atom one of its electrons. This is called reduction. Iodine reacts with hydrogen sulfide or hydrazine to make hydriodic acid. Iodine dissolves in oleum to make a bright blue solution of I and sulfur dioxide. This cation is also made when iodine reacts with antimony pentafluoride.
Iodine reacts with bases to make hypoiodite and iodide. The hypoiodite disproportionates to iodate and iodide. Iodine reacts with nitric acid and chlorates to make iodates, too. Iodine reacts violently with some metals like aluminium to make large amounts of heat and toxic vapors.
Iodine forms chemical compounds in several oxidation states: -1, +1, +3, +5, and +7. This is typical of the halogens except for fluorine. -1 compounds as iodides are the most common. Most organic iodine compounds are in the -1 oxidation state. Most iodides are colorless or reddish-yellow and are weak reducing agents. +1 and +3 compounds are quite rare. They are both oxidizing agents. +1 compounds are found as iodine monochloride and hypoiodites. +3 compounds are found as iodine trichloride or iodine trifluoride. +5 compounds are found as iodates and iodic acid. Iodine pentafluoride and iodine pentoxide are iodine compounds in the +5 state. +5 and +7 compounds are all strong oxidizing agents. +7 compounds are normally found as periodates and periodic acid. Iodine heptafluoride is also in the +7 oxidation state.
