The largest of the low-pressure systems are the extratropical cyclones and the cold-core polar cyclones which lie on the synoptic scale which in meteorology is a horizontal length of 1000 km or more. The Warm-core cyclones are the tropical cyclones, mesocyclones, and the polar lows that lie within the smaller mesoscale. The Subtropical cyclones are intermediate in size. Cyclones have also been on other planets outside of the Earth, such as Mars and Neptune. For example the Great Red Spot of Jupiter and the Great Black Spot of Neptune.
Cyclones are also referred to as hurricanes and typhoons. They consist of the eye, eyewall and rainbands.
The process of cyclone formation and intensification is described as Cyclogenesis. The formation of Extratropical cyclones comes as waves in large regions of enhanced midlatitude temperature contrasts which are called baroclinic zones. These zones contract to form weather fronts as the circulation of the cyclone closes and gets more intense. Later in their life cycle, cyclones form what is called an occluded front. The cyclone's track is then guided over the course of an 2 to 6 day life cycle by its steering flow of the polar or subtropical jetstream. Cyclones destroy many things when they come into contact with land such as crops, buildings, trees, etc.
Eye (cyclone)
The eye is an area of calm weather in the center of strong tropical cyclones. The cyclone's lowest barometric pressure occurs in the eye. It is usually circular and range between 30 and 65 km (20 to 40 mi) in diameter, though smaller and larger eyes can occur.
In case of a cyclone it is the place where all the winds coming inside in a spiral motion converge. In an anticyclone it is the part from where all winds move out from.
The region surrounding the eye is the eyewall, where the worst weather is seen in a cyclone. These have strong winds, lots of rain and lots of cloud. There are also outer bands, which surround the cyclone, which forms the greatest part of the storm. These have winds so strong they can even form other tornadoes.
Glasgow Coma Scale
Glasgow Coma Scale or GCS is a scale that is used to measure the consciousness of a person. It was invented in 1974 by "Graham Teasdale" and "Bryan J. Jennett", professors of neurosurgery at the University of Glasgow.
GCS is used in evaluation of patients, especially in ICUs. This scale consists of three tests, which are described below. A score is given for each test, and the GCS score is calculated by adding the scores given to each test. The maximum score is 15, which means the patient is fully conscious. The minimum score is 3, and is usually seen in patients with brain death or those in deep coma.
The scale comprises three tests: eye, verbal (talking) and motor (movement) responses.

House of Habsburg
Habsburg was a family of dukes, kings, and monarchs. They were very important in European history. They first ruled parts of Switzerland in the 13th century. They ruled Austria, later Austria-Hungary for more than 600 years, and also sometimes owned Spain and the Netherlands. They ruled the Holy Roman Empire from about 1280 to 1806. They also ruled the Kingdom of Sardinia until the middle 19th century.
A Treaty was made in Vienna in 1515 between the king of Poland and duke of Lithuania from the Jagiellon dynasty and Maximilian I, Holy Roman Emperor, duke of Austria from the Habsburg family. It said that if the kings of Bohemia and Hungary, (Jagiellons), were to die without male heirs the Duke of Austria would take over their territory.
The House of Habsburg became extinct in the 18th century. The senior branch ended when Charles II of Spain died in 1700 and was replaced by the House of Bourbon. The mental and physical handicaps of Charles II were probably caused by inbreeding between relatives in the royal houses of continental Europe. Marriages of close relatives occurred for five generations before him. He was the son of Philip IV, who married his sister's daughter.
The remaining branch went extinct in the male line in 1740 with the death of Holy Roman Emperor Charles VI and completely in 1780 with the death of his eldest daughter, Maria Theresa of Austria. It was succeeded by the Vaudemont branch of the House of Lorraine. The new successor house styled itself formally as House of Habsburg-Lorraine (German: "Habsburg-Lothringen"), although it was often referred to as simply the House of Habsburg.
The last empress was Zita of Bourbon-Parma. She died in Switzerland in 1989. She had ruled with her husband, Charles I of Austria, from 1916 to 1918.
Rhodesia
Rhodesia (, ), officially from 1970 the Republic of Rhodesia, was a republic in Southern Africa during the Cold War. It was the region that is now called Zimbabwe. The country replaced the British colony of Southern Rhodesia.
The official name of the country under British law was "Southern Rhodesia", but the government in Salisbury used the name "Rhodesia" instead. This situation dated back to October 1964, when the colony of Northern Rhodesia changed its name to Zambia following independence, so the colonial government felt that "Southern" Rhodesia should no longer be used because there was no "Northern" Rhodesia. However, Britain believed that only their government could change the colony's name and not the colony itself.
The British government adopted a policy called "no independence before majority rule", which dictated that colonies with a certain amount of white settlers would not become independent until they adopted a policy of majority rule. This had conflicted with the beliefs of the white minority Rhodesian Front, lead by Ian Smith, which believed that Rhodesia should become an independent country anyway. This continued until relations between the colony and the British government broke down in 1965.
On 11 November 1965, Smith's government issued a unilateral declaration of independence (UDI) from the United Kingdom. Many countries condemned the UDI and the United Nations Security Council placed sanctions on Rhodesia.
Rhodesia sought international recognition as a Commonwealth realm, with Queen Elizabeth II as "Queen of Rhodesia", but later severed it links to the British Crown by becoming a republic on 2 March 1970.
As early as 1960, many African nationalists began to challenge Rhodesia's minority rule policies. In 1964, tensions boiled over and the Rhodesian Bush War began. On one side, the minority rule government, led by Ian Smith, hoped to keep the whites in power. On the other side, the ZANU-PF, led by Robert Mugabe, fought for majority rule. After about 15 years of fighting, the Lancaster House Agreement was signed which allowed majority rule. This led to Zimbabwe's independence.
Westminster
Westminster is the central part of the City of Westminster, in London. It is on the north side of the River Thames. It contains the Houses of Parliament, Whitehall, Downing Street and Westminster Abbey.
Westminster is the official seat of the Prime Minister of the United Kingdom.

Akita may mean:
Ostara
Ostara is one of the eight festivals held by Wiccans every year. It is normally held at the time of the vernal equinox; that is, around 21 March in the Northern Hemisphere and 21 September in the Southern Hemisphere. At Ostara Wiccans celebrate the return of Spring.
Megalosaurus
Megalosaurus was a large meat-eating theropod dinosaur of the Middle Jurassic of Europe. It was found in 1824, and was the earliest dinosaur named. In 1827, Gideon Mantell included "Megalosaurus" in his geological survey of southeastern England. He gave the species its name, "Megalosaurus bucklandii".
