This is a list of some comets in the solar system. Periodic comets visit us again and again. Non-periodic comets visit us only once. On this list there is a "P" in front of the periodic comets. In front of non-periodic comets there is a "C". There is sometimes a number in front of the "P": it shows the number of times people saw the periodic comet visiting us.  Periodic comets. Periodic comets have a special place in astronomy, because their orbits are often the same. We know when they will visit us, and we can plan to watch them, and send space probes to look at them.  On August 24, 1994, the International Astronomical Union (IAU) standardized the way they name this type of comet. This system tells us which comet is which. The IAU chose the letter P for periodic comets and D for periodic comets that were lost or which broke into pieces. Other letters are C for "non-periodic" comets, and X for comets where we do not know their orbits. It uses A for objects people say are asteroids. Each name starts with a number, so two comets have the same name.
Many sports are played in water. The following is a list of water sports, divided by category. This list is not complete. Some of the sports include only one part   to swimming, as for example Triathlon. Near the water (20). Overall, there are a total of 39 water sports.
This is a list of tallest structures in the world, past and present of any type. Most of the structures are television broadcasting masts. There are also the taller tower-type structures (like the CN Tower) and the taller high rise buildings (like the Sears Tower).  The list also includes some other structures like oil platforms, electrical towers, bridge towers, etc. List is organized by absolute height since it includes many different classes of structures. This list includes quite a few masts. A mast is a man-made support structure, commonly used on sailing ships as support for sails, or on land as radio masts and towers used to support telecommunication equipment such as radio antennas ("aerials" in the UK). Terminology. There is often ambiguity between the terms "tower" and "mast". A tower is a self-supporting or cantilevered structure, while a mast is held up by stays or guys. Both towers and masts have limited floor space and are non-building structures, as opposed to regular buildings which have greater floor space for occupancy. The terminology is further confused through misuse. Skyscrapers are often referred to as "towers" and some towers use the term "mast". Ironically, "skyscraper" has some etymology from references to high sailboat masts. List by height. Notable structures between 300 and 350 m (984 and 1,148 ft). For practical purposes to keep the list to a reasonable length this part of list contains only notable structures. Structures taller than 350 m (1,148 ft) under construction. This is an "incomplete" list of structures taller tha|N|1,148 feet (350 m) under construction. Please correct (by adding further one or by putting completed structures in the upper table, if current height is over 1,148 feet (350 m)). List by continent. Current.

"The article about certain properties of databases is at ACID" "Sometimes acid is another name for the drug LSD (Lysergic acid diethylamide)" An acid is a substance that can donate a hydrogen ion (H+) (generally speaking, this will be a proton) to another substance. Acids have a pH less than 7.0.  A chemical can donate a proton if the hydrogen atom is attached to an electronegative atom like oxygen, nitrogen, or chlorine. Some acids are strong and others are weak. The weak acids hold on to some of their protons, while the strong acids let go of all of them. All acids will release hydrogen ions into solutions. The amount of ions that get released per molecule will determine if the acid is weak or strong. Weak acids are acids that partially release the hydrogen atoms that are attached. These acids, then, may lower pH by dissociation of hydrogen ions, but not completely. Weak acids generally have a pH value of 4-6 while strong acids have a pH value of 1 to 3. A base is an acid's "chemical opposite." A base is a substance that will accept the acid's hydrogen atom. Bases are molecules that can split apart in water and release hydroxide ions. How acids work. Acids and bases typically exist together in equilibrium. This means that within a sample of an acid, some molecules will give up their protons and others will accept them. Even water is a mixture of an acidic ion, H3O+ (called a hydronium ion) and a basic ion, OH- (called a hydroxide ion). When acids are diluted (mixed in water) they release H+ ions. These H ions cannot exist independently, so they combine with water to form Hydronium ion. A hydronium ion will give up its proton to a hydroxide ion, forming two molecules of H2O, which is neutral. This reaction happens continuously in a sample of water, but overall the sample is neutral because there are equal amounts of hydronium and hydroxide in the sample. For most reactions, however, the acids and bases
A white dwarf is a compact star. Their matter is squashed together. Gravitation has pulled the atoms close together, and taken off their electrons. The mass of a white dwarf is similar to the mass of the Sun, but its volume is similar to that of the Earth. White dwarfs are the final evolutionary state of all stars whose mass is not high enough to become a neutron star. Over 97% of the stars in the Milky Way will become white dwarf stars.§1 After the hydrogen–fusing lifetime of a main-sequence star ends, it will expand to a red giant which fuses helium to carbon and oxygen in its core. If a red giant does not have enough mass to fuse carbon, around 1 billion K, inactive carbon and oxygen will build up at its center. After shedding its outer layers to form a planetary nebula, it will leave behind the core, which is the white dwarf. The material in a white dwarf no longer undergoes fusion reactions, so the star has no source of energy. It is not supported by the heat of fusion against gravitational collapse. A star like our Sun will become a white dwarf when it has run out of fuel. Near the end of its life, it will go through a red giant stage, and then lose most of its gas, until what is left contracts and becomes a young white dwarf. History. White dwarfs were discovered in the 18th century. The first white dwarf star, called 40 Eridani B, was discovered on 31 January 1783 by William Herschel.p73 It is part of a three star system called 40 Eridani. The second white dwarf was discovered in 1862, but was at first thought to be a red dwarf. It was a small star near the star Sirius. This companion star, called Sirius B, had a surface temperature of about 25,000 kelvin, so it was thought of as a hot star. However, Sirius B was about 10,000 times fainter than the primary, Sirius A. Scientists have discovered that the mass of Sirius B is almost the same as that of the Sun. This means that once, Sirius B was a star similar
A beach is a landform along the coast of an ocean, sea, lake, or river. It usually consists of loose particles, such as sand, gravel, shingle, or pebbles. The particles of a beach are sometimes biological in origin, such as mollusc shells or bits of coral and sometimes bits of igneous rock, but the most common mineral in beaches is quartz. Beaches are natural landing and launching places for boats, and landing craft are specially made for beaches. People often use beaches for recreation. They swim, bask in the sun, or just relax. The most popular beaches have fine white or light-colored sand and warm water to swim in. Beaches are also used for diving or for seeing marine life. Among the world's most popular and well-known beaches are Aruba (Dutch Caribbean), Long Beach (Canada), Copacabana Beach (Brazil), Hot Water Beach (New Zealand), Megan Bay (St. Thomas), Kailua Beach (Hawaii), Zandvoort Beach (Netherlands), Jeffreys Bay (South Africa), Bondi Beach (Australia) and Lake Como beaches (Italy). Taking holidays on the beach is something of a British cultural export. Early railways in the 19th century took people to places they had never seen before. This tourism was made possible by the industrial revolution. Whole seaside resort towns grew to support visitors, where before there were just villages. Vacations at the sea became common all over the world. Beaches are never static. They are always being built up or eroded, more quickly than other landforms. Over time the boundary between the land and the sea changes. New Romney, a small town in Kent, is one of the Cinque Ports, a mile from the sea. In Henry VIII's time it was a port on the south coast of England. The growth of Dungeness has cut it off from the sea. Dungeness is a huge shingle beach.
A mental illness is an illness of the mind. It can be a psychiatric disorder, a psychological disorder, mental disease, mental breakdown, nervous breakdown, or mental health conditions. People with a mental illness may behave in strange ways or have strange thoughts. Mental illnesses can create problems for what a person has to do every day.  Mental illnesses develop during the life of a person. This may be linked to genes and experience. What people call mental illness has changed over time. The Diagnostic and Statistical Manual of Mental Disorders (DSM) by the American Psychiatric Association is used around the world. People with a mental illness sometimes have problems dealing with other people, or have a hard time doing what would be easy for everyone else. Some mental illnesses can be treated with medicine.  In some cases, mental illnesses change the way the brain works. Many conditions which affect the brain are not mental illnesses, because they do not change the way people think: Neither epilepsy nor Parkinson's disease is a mental illness, even though they both affect the brain. Common mental problems. According to the New Freedom Commission on Mental Health in the United States, the most common type of disability in the United States is major mental illnesses (which include major depression, bipolar disorder, personality disorders, body dysmorphic disorder, schizophrenia, and obsessive-compulsive disorder). Thirty-three percent of North American adults will have a mental illness in a given year, according to the National Alliance on Mental Illness. But in more than half of these cases, the mental illness is not bad enough to disrupt daily life activities. Partly inherited. There is a genetic basis which makes some people more likely to develop mental illness. A study published in "The Lancet", a medical journal, found the same set of genetic markers in people with five different disorders: schizophrenia, bipolar disorder, autism, major depression, and attention deficit hyperactivity disorder (ADHD). Treatment of mental illnesses. Mental illnesses can be treated by: Some more controversial treatments include Violence. Even though the media show this differently, studies have shown that people with a severe mental illness are not necessarily violent. Statistically, violence is often caused by factors such as drug abuse, or those related to the personal, social and
Depression (also called major depressive disorder, unipolar depression or clinical depression) is a mental illness. Many people think that depression just means a person is very sad. However, depression can cause many symptoms in the body as well as mood problems. Diagnosis. The ICD-10 is used around the world to diagnose people with illnesses like depression. As per the ICD-10, for a person to be diagnosed with depression, their symptoms have to last for at least two weeks.  The symptoms must happen every day, or almost every day. These symptoms also have to cause problems in a person's life (like their work life, family life, social life, or other important parts of their life).  Symptoms. Usually, for depression to be diagnosed, a person must have five or more of these symptoms: Prevalence. It is impossible to get an exact number of how many people have depression. There are many reasons for this. For example: In different cultures. Major depression is one of the most common mental illnesses in the United States (US). In 2014, 15.7 million adults in the United States had at least one episode of major depression. This is about 6.7% of all adults in the United States. Around the world, depression causes more disability than any other mental health or behavioral illness, according to the World Health Organization. However, the prevalence of depression is different in different cultures and countries. Research. Prince (1968) found virtually no depression in most Asian and African countries. However, psychologists such as Zhang and Kleinman have found disorders with similar symptoms, but different names.  For instance, in the 1980s, Zhang found that in China, there was little mention of depression. However, instead, a disorder called Neurasthenia was far more common. When interviewing Neurasthenia patients, Zhang found that their symptoms matched the symptoms of depression by over 80%. While the term "depression" was practically unheard of in China, Neurasthenia could well have been a similar disorder – or the same thing. It is also important to take in different cultures ways of classifying depression. For instance, in
The Qur'an () is the central holy book of Islam. The Qur'an is considered by Muslims to be "The Word of Allah (God)". This book is believed to have been revealed to the prophet Muhammad. Some Muslims call it the "Final Testament". For Muslims, the Qur'an is Allah's last revelation, the last in a chain of many revelations such as the "Tawrat" (Torah), the "Zabur" (Psalms), the "Injeel" (Gospel), the "Scrolls of Abraham", and the "Scrolls of Moses". It has been written and read only in Arabic for more than 1,400 years. But, because many Muslims around the world do not understand Arabic, the meaning of the Qur'an is also given in other languages, so that readers can understand better what the Arabic words in the Qur'an mean. These books are like dictionaries to the Qur'an - they are not read as part of the religion of Islam, to replace the Arabic Qur'an. Muslims believe that these translations are not the true Qur'an; only the Arabic copy is the true Qur'an.  For most self-identified Muslims, the Qur'an is used with the hadith to interpret Sharia law (Islamic holy law). It is by far the most important and authoritative document, however, and supersedes hadiths and all earlier revelations, such as the Torah and the Bible. Saudi Arabia holds that the Qur'an is the country's constitution, although it is supplemented by more recent documents in modern Arabic.  For Shi'a Muslims, the Qur'an is used together with interpretations by special imams, especially such being a descendant from Muhammad's family, the "Ahl al-Bayt". Others use the Islamic methodology of (), which refers to interpreting the Qur'an with/through the Bible. This approach adopts canonical Arabic versions of the Bible, including the Tawrat and the Injil, both to illuminate and to add exegetical depth to the reading of the Qur'an. Notable Muslim (commentators) of the Bible and Qur'an who weaved biblical texts together with Qur'anic ones include Abu al-Hakam Abd al-Salam bin al
Sir Anthony Charles Lynton "Tony" Blair (born 6 May 1953) is a British politician who served as Prime Minister of the United Kingdom from 1997 to 2007. He was Leader of the Labour Party from 1994 to 2007 and Member of Parliament (MP) for Sedgefield from 1983 to 2007. On the day he stood down as Prime Minister and MP, he was made official Envoy of the Quartet on the Middle East on behalf of the United Nations, the European Union, the United States and Russia. Blair was elected Leader of the Labour Party in the 1994 leadership election following the sudden death of his predecessor, John Smith. Under Blair's leadership the party abandoned many policies it had held for decades. Labour won a landslide victory in the 1997 general election, which ended 18 years of Conservative rule with the heaviest Conservative defeat since 1832. He was the Labour Party's longest-serving Prime Minister and the only leader to have taken the party to three uninterrupted general election victories. Gordon Brown, Chancellor of the Exchequer during all Blair's ten years in office, succeeded him as party leader and Prime Minister in 2007. Early life. Blair was born at Queen Mary Maternity Home in Edinburgh on 6 May 1953. He was the second son of Leo and Hazel Blair. Blair joined the Labour Party in 1975. Career. Blair was a lawyer before becoming a politician. He married Cherie Booth, also a lawyer, who graduated from the London School of Economics with a first-class honours degree. Blair himself left Oxford University with a second-class degree. They have four children: Euan, Nicky, Kathryn, and Leo. There was a controversy over Blair sending Euan to a grant-maintained school. As a result of this, Alastair Campbell discovered Blair "standing stark naked reading the "Daily Mail"." As Prime Minister. As Leader of the Labour Party, he won the 1997, 2001 and 2005 UK general elections. Blair is the first and only Labour Party leader to have won three general elections in a row. He attributes his success in politics
An accident is when something goes wrong when it is not meant to. Physical accidents are things like collisions, injuries, and falling. Non-physical accidents are things like telling someone a secret without meaning to, forgetting something important, or deleting an important computer file. Road accidents kill thousands of people each month in the United States, and thousands each week in the world. They injure more thousands each week. The majority involve a car but there are also many bus, truck and bicycle accidents. Aircraft crashes, ship sinkings and other transport accidents also attract much attention.  Injuries from accidents, however, are more numerous at home than elsewhere. They attract less attention because only a few people are hurt at a time.  Often, accidents are investigated so that we can learn how to avoid them in the future. Sometimes by studying an accident we can discover new things, for example penicillin. Most of the deaths resulting from injuries are caused by fire accidents. Thus, accidental fires are one of the leading causes of unintentional deaths. The main cause of death in fire incidents is burning, but inhalation of smoke and toxic gas causes death as well. Often the cause of the fire is very simple and unexpected, such as forgetting a candle near something flammable, defect in the hardware, or old electrical wires. So most of the large fires are caused by simple reasons. Work accidents. Industrial accidents such as mine cave-ins and the West Gate Bridge collapse also kill and maim many workers. The Bhopal disaster killed thousands, mostly not workers.  An accident at work is defined as an external, sudden and violent event. Work accidents happen while an someone is working. It may cause the injury or death of the worker or someone else. For an accident to be a work accident, there must be a direct or indirect relationship of cause and effect between the accident and the work. Many construction workers are injured. There are multiple reasons for that, but the main reason is working on the edge of high buildings without using a safety belt. Thus, you have to follow the safety rules when you are working on these places. Chemical accidents can happen in a laboratory. Especially, some students make chemical mistakes that injure them seriously.
Acne is an infection of the skin, caused by changes in the sebaceous glands. The most common form of acne is called acne vulgaris, which means "common acne". The redness comes from the inflammation of the skin in response to the infection. Oils from the glands combine with dead skin cells to block hair follicles. Under the blocked pore, oil builds up. Skin bacteria can then grow very quickly. This infection makes the skin become swollen and red, which becomes visible. The face, chest, back, and upper arms are most common places for acne to happen. Acne is common during puberty, when a person is turning from a child into an adult, because of high levels of hormones. Acne becomes less common as people reach adulthood. There are lots of acne treatment methods available, including natural treatments. Effects of acne. People of all ages can get acne, although it occurs more commonly in adolescents. Acne can affect people physically, psychologically, and socially. Physical effects. Acne causes scarring, and acne pustules can be very painful and sensitive. Psychological effects. People suffering from a bad case of acne, especially adolescents, can develop low self-esteem which can lead to depression. Social effects. Low self-esteem issues can make a person suffering from acne withdraw from many social events. It makes developing new personal relationships (especially love relationships) more difficult. Low self-esteem can also cause problems with career advancement as the person may find it difficult to present a positive attitude. This may sometimes even lead to suicidal thoughts. Some of the treatments for acne have also shown a link with more suicide attempts. Causes of acne. Exactly why some people get acne and some do not is not completely known. These can cause acne, or make it worse: Aspirin reduces inflammation which in result, reduces facial redness due to acne. Treatments. Many things are sold to treat acne, the most popular being .Benzoyl peroxide: Popping a pimple should not be done by anyone but a qualified dermatologist. Pimple popping irritates skin, can make the bacteria spread, and can cause scars. If you must pop a pimple yourself, it is advised to apply warm
