A congenital heart defect (CHD), also known as a congenital heart anomaly or congenital heart disease, is a problem in the structure of the heart that is present at birth. Signs and symptoms depend on the specific type of problem. Symptoms can vary from none to life-threatening. When present they may include rapid breathing, bluish skin, poor weight gain, and feeling tired. It does not cause chest pain. Most congenital heart problems do not occur with other diseases. Complications that can result from heart defects include heart failure.The cause of a congenital heart defect is often unknown. Certain cases may be due to infections during pregnancy such as rubella, use of certain medications or drugs such as alcohol or tobacco, parents being closely related, or poor nutritional status or obesity in the mother. Having a parent with a congenital heart defect is also a risk factor. A number of genetic conditions are associated with heart defects including Down syndrome, Turner syndrome, and Marfan syndrome. Congenital heart defects are divided into two main groups: cyanotic heart defects and non-cyanotic heart defects, depending on whether the child has the potential to turn bluish in color. The problems may involve the interior walls of the heart, the heart valves, or the large blood vessels that lead to and from the heart.Congenital heart defects are partly preventable through rubella vaccination, the adding of iodine to salt, and the adding of folic acid to certain food products. Some defects do not need treatment. Others may be effectively treated with catheter based procedures or heart surgery. Occasionally a number of operations may be needed, or a heart transplant may be required. With appropriate treatment, outcomes are generally good, even with complex problems.Heart defects are the most common birth defect. In 2015 they were present in 48.9 million people globally. They affect between 4 and 75 per 1,000 live births depending upon how they are diagnosed. About 6 to 19 per 1,000 cause a moderate to severe degree of problems. Congenital heart defects are the leading cause of birth defect-related deaths. In 2015 they resulted in 303,300 deaths down from 366,000 deaths in 1990.

Examples of early public web portals were AOL, Excite, Netvibes, iGoogle, MSN, Naver, Lycos, Prodigy, Indiatimes, Rediff, and Yahoo!. See for example, the "My Yahoo!" feature of Yahoo! that may have inspired such features as the later Google "iGoogle" (discontinued as of November 1, 2013.) The configurable side-panels of, for example, the modern Opera browser and the option of "speed dial" pages by most browsers continue to reflect the earlier "portal" metaphor.

Question: Aol is an example of what?
Answer: early public web portals
Istanbul is near the North Anatolian Fault, close to the boundary between the African and Eurasian Plates. This fault zone, which runs from northern Anatolia to the Sea of Marmara, has been responsible for several deadly earthquakes throughout the city's history. Among the most devastating of these seismic events was the 1509 earthquake, which caused a tsunami that broke over the walls of the city and killed more than 10,000 people. More recently, in 1999, an earthquake with its epicenter in nearby İzmit left 18,000 people dead, including 1,000 people in Istanbul's suburbs. The people of Istanbul remain concerned that an even more catastrophic seismic event may be in the city's near future, as thousands of structures recently built to accommodate Istanbul's rapidly increasing population may not have been constructed properly. Seismologists say the risk of a 7.6-magnitude or greater earthquake striking Istanbul by 2030 is more than 60 percent.

Question: What city is found close to the North Anatolian Fault?
Answer: Istanbul
Istanbul's persistently high humidity reaches 80 percent most mornings. Because of this, fog is very common, although more so in northern parts of the city and away from the city center. Dense fog disrupts transportation in the region, including on the Bosphorus, and is common during the autumn and winter months when the humidity remains high into the afternoon. The humid conditions and the fog tend to dissipate by midday during the summer months, but the lingering humidity exacerbates the moderately high summer temperatures. During these summer months, high temperatures average around 29 °C (84 °F) and rainfall is uncommon; there are only about fifteen days with measurable precipitation between June and August. The summer months also have the highest concentration of thunderstorms.Winter is colder in Istanbul than in most other cities around the Mediterranean Basin, with low temperatures averaging 1–4 °C (34–39 °F). Lake-effect snow from the Black Sea is common, although difficult to forecast, with the potential to be heavy and—as with the fog—disruptive to the city's infrastructure. Spring and autumn are mild, but often wet and unpredictable; chilly winds from the northwest and warm gusts from the south—sometimes in the same day—tend to cause fluctuations in temperature. Overall, Istanbul has an annual average of 130 days with significant precipitation, which amounts to 810 millimeters (31.9 in) per year. The highest and lowest temperatures ever recorded in the city center on the Marmara coast are 40.5 °C (105 °F) and −16.1 °C (3 °F). The greatest rainfall recorded in a day is 227 millimeters (8.9 in), and the highest recorded snow cover is 80 centimeters (31 in).

Question: What is usually characterized with Spring and autumn?
Answer: mild, but often wet and unpredictable

Question: When are there a higher concentration of thunder storms?
Answer: summer months
Premenstrual syndrome (PMS) refers to physical and emotional symptoms that occur in the one to two weeks before a woman's period. Symptoms often vary between women and resolve around the start of bleeding. Common symptoms include acne, tender breasts, bloating, feeling tired, irritability, and mood changes. Often symptoms are present for around six days. A woman's pattern of symptoms may change over time. Symptoms do not occur during pregnancy or following menopause.Diagnosis requires a consistent pattern of emotional and physical symptoms occurring after ovulation and before menstruation to a degree that interferes with normal life. Emotional symptoms must not be present during the initial part of the menstrual cycle. A daily list of symptoms over a few months may help in diagnosis. Other disorders that cause similar symptoms need to be excluded before a diagnosis is made.The cause of PMS is unknown. Some symptoms may be worsened by a high-salt diet, alcohol, or caffeine. The underlying mechanism is believed to involve changes in hormone levels. Reducing salt, caffeine, and stress along with increasing exercise is typically all that is recommended in those with mild symptoms. Calcium and vitamin D supplementation may be useful in some. Anti-inflammatory drugs such as naproxen may help with physical symptoms. In those with more significant symptoms birth control pills or the diuretic spironolactone may be useful.Up to 80% of women report having some symptoms prior to menstruation. These symptoms qualify as PMS in 20 to 30% of pre-menopausal women. Premenstrual dysphoric disorder (PMDD) is a more severe form of PMS that has greater psychological symptoms. PMDD affects three to eight percent of pre-menopausal women. Antidepressant medication of the selective serotonin reuptake inhibitors class may be used in addition to usual measures for in PMDD.

Question: What does PMDD stand for?
Answer: Premenstrual dysphoric disorder
Up to 80% of women of child-bearing age report having some symptoms prior to menstruation. These symptoms qualify as PMS in 20 to 30% of women and in three to eight percent are severe.

Question: What percentage of women have PMS?
Answer: Up to 80%
Thant died of lung cancer in New York on 25 November 1974. By that time, Burma was ruled by a military junta which refused him any honours. The then Burmese president Ne Win was envious of Thant's international stature and the respect that was accorded him by the Burmese populace. Ne Win also resented Thant's close links with the democratic government of U Nu which Ne Win had overthrown in a coup d'état on 2 March 1962.

Question: Burma refused honors for what individual due to being ran by a military junta?
Answer: Thant
Al-Rawda Mosque, which is located on Sinai's main coastal highway connecting the city of Port Said to Gaza, belongs to the local Jarir clan, of the Sawarka tribe, who follow the Jaririya (Gaririya) Sufi order—an offshoot of the movement of Abu Ahmed al-Ghazawi, of the broader Darqawa order. The mosque is on the road between El Arish and Bir al-Abed. The mosque has a smaller zawiyah, a Sufi lodge, attached.According to local media, attackers in four off-road vehicles planted three bombs; the attackers used the burning wrecks of cars to block off escape routes. After their detonation, they launched rocket propelled grenades and opened fire on worshipers during the crowded Friday prayer at al-Rawda near Bir al-Abed. When ambulances arrived to transport the wounded to hospitals, the attackers opened fire on them as well, having selected ambush points from which to target them. Local residents quickly responded, bringing the wounded to hospitals in their own cars and trucks, and even taking up weapons to fight back.

Question: How did the local residents transport the wounded?
Answer: their own cars and trucks

Question: Where did the attackers set up ambush points to further target the victims?
Answer: hospitals
PA 11 is a biopolymer derived from natural oil. It is also known under the tradename Rilsan B, commercialized by Arkema. PA 11 belongs to the technical polymers family and is not biodegradable. Its properties are similar to those of PA 12, although emissions of greenhouse gases and consumption of nonrenewable resources are reduced during its production. Its thermal resistance is also superior to that of PA 12. It is used in high-performance applications like automotive fuel lines, pneumatic airbrake tubing, electrical cable antitermite sheathing, flexible oil and gas pipes, control fluid umbilicals, sports shoes, electronic device components, and catheters.

Question: What are some of its uses?
Answer: automotive fuel lines, pneumatic airbrake tubing, electrical cable antitermite sheathing, flexible oil and gas pipes, control fluid umbilicals, sports shoes, electronic device components, and catheters
Although he continued to operate from Munich, by mid-1978 Bergman had overcome some of his bitterness toward the Swedish government. In July of that year he visited Sweden, celebrating his sixtieth birthday on the island of Fårö, and partly resumed his work as a director at Royal Dramatic Theatre. To honour his return, the Swedish Film Institute launched a new Ingmar Bergman Prize to be awarded annually for excellence in filmmaking. Still, he remained in Munich until 1984. In one of the last major interviews with Bergman, conducted in 2005 on the island of Fårö, Bergman said that despite being active during the exile, he had effectively lost eight years of his professional life.

Question: What did Bergman say during his last interview conducted in 2005?
Answer: despite being active during the exile, he had effectively lost eight years of his professional life

Considered to be among the most accomplished and influential filmmakers of all time, Bergman's films include Smiles of a Summer Night (1955), The Seventh Seal (1957), Wild Strawberries (1957), Persona (1966), Cries and Whispers (1972), Scenes from a Marriage (1973), and Fanny and Alexander (1982); the last two exist in extended television versions.

Question: How long did Ernst Ingmar Bergman live?
Answer: 14 July 1918 – 30 July 2007
Science, also widely referred to as Science Magazine, is the peer-reviewed academic journal of the American Association for the Advancement of Science (AAAS) and one of the world's top academic journals. It was first published in 1880, is currently circulated weekly and has a subscriber base of around 130,000. Because institutional subscriptions and online access serve a larger audience, its estimated readership is 570,400 people.The major focus of the journal is publishing important original scientific research and research reviews, but Science also publishes science-related news, opinions on science policy and other matters of interest to scientists and others who are concerned with the wide implications of science and technology. Unlike most scientific journals, which focus on a specific field, Science and its rival Nature cover the full range of scientific disciplines. According to the Journal Citation Reports, Science's 2015 impact factor was 34.661.Although it is the journal of the AAAS, membership in the AAAS is not required to publish in Science. Papers are accepted from authors around the world. Competition to publish in Science is very intense, as an article published in such a highly cited journal can lead to attention and career advancement for the authors. Fewer than 7% of articles submitted are accepted for publication.

Question: Who is Science magazine's main competition?
Answer: Nature
About 86% of the gas released from these structures is methane, with much less carbon dioxide and nitrogen emitted. Ejected materials are most often a slurry of fine solids suspended in water that may contain a mixture of salts, acids and various hydrocarbons.

Question: what mixtures do Ejected Materials have?
Answer: a mixture of salts, acids and various hydrocarbons.
The coastline is inhabited by marine mammals, like sea lions, elephant seals and fur seals. Southern right whales can be found in Golfo Nuevo and Golfo San José, protected bodies of water located between the peninsula and the Patagonian mainland. These baleen whales come here between May and December, for mating and giving birth, because the water in the gulf is quieter and warmer than in the open sea. Orcas can be found off the coast, in the open sea off the peninsula. In this area, they are known to beach themselves on shore to capture sea lions and elephant seals.

Question: WHat sort of sea life live along the coastline?
Answer: marine mammals, like sea lions, elephant seals and fur seals
High-concentration H2O2 is referred to as "high-test peroxide" (HTP). It can be used either as a monopropellant (not mixed with fuel) or as the oxidizer component of a bipropellant rocket. Use as a monopropellant takes advantage of the decomposition of 70–98% concentration hydrogen peroxide into steam and oxygen. The propellant is pumped into a reaction chamber, where a catalyst, usually a silver or platinum screen, triggers decomposition, producing steam at over 600 °C (1,112 °F), which is expelled through a nozzle, generating thrust. H2O2 monopropellant produces a maximal specific impulse (Isp) of 161 s (1.6 kN·s/kg). Peroxide was the first major monopropellant adopted for use in rocket applications. Hydrazine eventually replaced hydrogen-peroxide monopropellant thruster applications primarily because of a 25% increase in the vacuum specific impulse. Hydrazine (toxic) and hydrogen peroxide (less-toxic [ACGIH TLV 0.01 and 1 ppm respectively]) are the only two monopropellants (other than cold gases) to have been widely adopted and utilized for propulsion and power applications. The Bell Rocket Belt, reaction control systems for X-1, X-15, Centaur, Mercury, Little Joe, as well as the turbo-pump gas generators for X-1, X-15, Jupiter, Redstone and Viking used hydrogen peroxide as a monopropellant.As a bipropellant, H2O2 is decomposed to burn a fuel as an oxidizer. Specific impulses as high as 350 s (3.5 kN·s/kg) can be achieved, depending on the fuel. Peroxide used as an oxidizer gives a somewhat lower Isp than liquid oxygen, but is dense, storable, noncryogenic and can be more easily used to drive gas turbines to give high pressures using an efficient closed cycle. It can also be used for regenerative cooling of rocket engines. Peroxide was used very successfully as an oxidizer in World War II German rocket motors (e.g. T-Stoff, containing oxyquinoline stabilizer, for both the Walter HWK 109-500 Starthilfe RATO externally podded monopropellant booster system, and for the Walter HWK 109-509 rocket motor series used for the Me 163B), most often used with C-Stoff in a self-igniting hypergolic combination, and for the low-cost British Black Knight and Black Arrow launchers.

Question: What is another use of peroxide in the field of rocket engines?
Answer: regenerative cooling
Animation is often used in advertisements. The pictures can vary from hand-drawn traditional animation to computer animation. By using animated characters, an advertisement may have a certain appeal that is difficult to achieve with actors or mere product displays. Animation also protects the advertisement from changes in fashion that would date it. For this reason, an animated advertisement (or a series of such advertisements) can be very long-running, several decades in many instances. Notable examples are the series of advertisements for Kellogg's cereals, starring Snap, Crackle and Pop and also Tony the Tiger. The animation is often combined with real actors. Animated advertisements can achieve lasting popularity. In any popular vote for the most memorable television advertisements in the UK, such as on ITV or Channel 4, the top positions in the list invariably include animations, such as the classic Smash and Creature Comforts advertisements.

Question: why use animated characters ?
Answer: an advertisement may have a certain appeal that is difficult to achieve

Question: What can end up running very long, possibly for decades?
Answer: an animated advertisement
Many television advertisements feature songs or melodies ("jingles") or slogans designed to be striking and memorable, which may remain in the minds of television viewers long after the span of the advertising campaign. Some of these ad jingles or catch-phrases may take on lives of their own, spawning gags that appear in films, television shows, magazines, comics, or literature. These long-lasting advertising elements may be said to have taken a place in the pop culture history of the demographic to whom they appeared. An example is the enduring phrase, "Winston tastes good like a cigarette should", from the eighteen-year advertising campaign for Winston cigarettes from the 1950s to the 1970s. Variations of this dialogue and direct references to it appeared as long as two decades after the advertising campaign expired. Another example is "Where's the Beef?", which grew so popular it was used in the 1984 presidential election by Walter Mondale. Another popular catch-phrase is "I've fallen and I can't get up", which still appears occasionally, over two decades after its first use. Some advertising agency executives have originated more than one enduring slogan, such as Mary Wells Lawrence, who is responsible for such famous slogans as "Raise your hand if you're Sure", "I♥New York" and "Trust the Midas touch."

Question: What two traits are very important for television advertisements?
Answer: striking and memorable
Gazelles, oryx, sand cats, and spiny-tailed lizards are just some of the desert-adapted species that survive in this extreme environment, which features everything from red dunes to deadly quicksand.  The climate is mostly dry (the major part receives around 100 mm (3.9 in) of rain per year but some very rare places receive as little as 50 mm), and temperatures oscillate between very high heat and seasonal night time freezes. It is part of the deserts and xeric shrublands biome and the Palearctic ecozone.

Question: What type of species is a Gazelle?
Answer: desert-adapted
The Arabian Desert has a subtropical, hot desert climate, close to the climate of the Sahara Desert ; the world's largest hot desert. In fact, the Arabian Desert is an extension of the Sahara Desert over the Arabian peninsula. The climate is mainly hot and dry with plenty of sunshine throughout the year. The rainfall amount is generally around 100 mm, and the driest areas can receive between 30 and 40 mm of annual rain. Such dryness remains very rare throughout the desert, however. There are hardly any hyperarid

Question: What is the climate of the region typically?
Answer: hot and dry
The Arabian desert ecoregion holds little biodiversity, although a few endemic plants grow here. Many species, such as the striped hyena, jackal and honey badger have become extirpated due to hunting, human encroachment and habitat destruction.  Other species have been successfully re-introduced, such as the Arabian sand gazelle, and are protected at a number of reserves.  Overgrazing by livestock, off-road driving, and human destruction of habitat are the main threats to this desert ecoregion.

Question: What human interactions have caused the extirpation of honey badgers?
Answer: human encroachment and habitat destruction
The 1928 Games were the first true Winter Olympics held on its own as they were not in conjunction with a Summer Olympics. The preceding 1924 Games were retroactively renamed the inaugural Winter Olympics, though they had been in fact part of the 1924 Summer Olympics. All preceding Winter Events of the Olympic Games were the winter sports part of the schedule of the Summer Games, and not held as a separate Winter Games. These games also replaced the now redundant Nordic Games, that were held quadrennially since early in the century.

Question: What was the new name given to the 1924 Olympics?
Answer: Winter Olympics

Question: The games replaced what other event?
Answer: Nordic Games
Harris' first film role as an adult was 1995's Animal Room, although he portrayed a teenager. His subsequent film work has included supporting roles in The Next Best Thing, Undercover Brother, and Starship Troopers. Harris plays a fictionalized, hyper-womanising, lewd version of himself in the Harold and Kumar stoner comedy films Harold & Kumar Go to White Castle, Harold & Kumar Escape from Guantanamo Bay, and A Very Harold & Kumar 3D Christmas.

Question: Is the role that Harris plays considered to be realistic of himself or fictionalized?
Answer: fictionalized,
The Su-27 had the Soviet Union's first operational fly-by-wire control system, based on the Sukhoi OKB's experience with the T-4 bomber project. Combined with relatively low wing loading and powerful basic flight controls, it makes for an exceptionally agile aircraft, controllable even at very low speeds and high angle of attack. In airshows the aircraft has demonstrated its maneuverability with a Cobra (Pugachev’s Cobra) or dynamic deceleration – briefly sustained level flight at a 120° angle of attack.

Question: What kind of control was used during the first Soviet Union operation?
Answer: fly-by-wire
