Fire

Fire is the rapid oxidation of a material in the exothermic chemical process of combustion, releasing heat, light, and various reaction products. Slower oxidative processes like rusting or digestion are not included by this definition.

Fire is hot because conversion of the weak double bond in molecular oxygen, O₂, to the stronger bonds in the combustion products carbon dioxide and water releases energy (418 kJ per 32 g of O₂); the bond energies of the fuel play only a minor role here. At a certain point in the combustion reaction, called the ignition point, flames are produced. The flame is the visible portion of the fire. Flames consist primarily of carbon dioxide, water vapor, oxygen and nitrogen. If hot enough, the gases may become ionized to produce plasma. Depending on the substances alight, and any impurities outside, the color of the flame and the fire's intensity will be different.

Fire in its most common form can result in conflagration, which has the potential to cause physical damage through burning. Fire is an important process that affects ecological systems around the globe. The positive effects of fire include stimulating growth and maintaining various ecological systems. Fire has been used by humans for cooking, generating heat, light, signaling, and propulsion purposes. The negative effects of fire include hazard to life and property, atmospheric pollution, and water contamination. If fire removes protective vegetation, heavy rainfall may lead to an increase in soil erosion by water. Also, when vegetation is burned, the nitrogen it contains is released into the atmosphere, unlike elements such as potassium and phosphorus which remain in the ash and are quickly recycled into the soil. This loss of nitrogen caused by a fire produces a long-term reduction in the fertility of the soil, which only slowly recovers as nitrogen is "fixed" from the atmosphere by lightning and by leguminous plants such as clover.

Fire!!

Fire!! was an African-American literary magazine published in New York City in 1926 during the Harlem Renaissance. The publication was started by Wallace Thurman, Zora Neale Hurston, Aaron Douglas, John P. Davis, Richard Bruce Nugent, Gwendolyn Bennett, Lewis Grandison Alexander, Countee Cullen, and Langston Hughes. After it published one issue, its quarters burned down, and the magazine ended.

History

Fire!! was conceived to express the African-American experience during the Harlem Renaissance in a modern and realistic fashion, using literature as a vehicle of enlightenment. The magazine's founders wanted to express the changing attitudes of younger African Americans. In Fire!! they explored edgy issues in the Black community, such as homosexuality, bisexuality, interracial relationships, promiscuity, prostitution, and color prejudice.

Langston Hughes wrote that the name was intended to symbolize their goal "to burn up a lot of the old, dead conventional Negro-white ideas of the past ... into a realization of the existence of the younger Negro writers and artists, and provide us with an outlet for publication not available in the limited pages of the small Negro magazines then existing.". The magazine's headquarters burned to the ground shortly after it published its first issue. It ended operations.

County Tyrone

County Tyrone (from Irish: Tír Eoghain, meaning "land of Eoghan") is one of the six counties of Northern Ireland. Adjoined to the south-west shore of Lough Neagh, the county covers an area of 3,155 km² (1218 sq mi) and has a population of about 177,986, with its county town being Omagh. It is also one of the thirty-two traditional counties of Ireland and is within the historic province of Ulster.

Tyrone is the eighth largest of Ireland's thirty-two counties by area and tenth largest by population. It is the second largest of Ulster's nine counties by area and fourth largest by population. The county is no longer used as an administrative division for local government purposes, but retains a strong identity in popular culture.

Name

The name Tyrone is derived from Irish Tír Eoghain, meaning "land of Eoghan", the name given to the conquests made by the Cenél nEógain from the provinces of Airgíalla and Ulaid. Historically, it was anglicised as Tirowen or Tyrowen, which are closer to the Irish pronunciation.

Tyrone (UK Parliament constituency)

Tyrone is a former UK Parliament constituency in Ireland, returning two Members of Parliament.

Boundaries and Boundary Changes

This constituency comprised the whole of County Tyrone, except the Parliamentary borough of Dungannon.

It returned two MPs 1801-1885. It was an original constituency represented in Parliament when the Union of Great Britain and Ireland was created on 1 January 1801.

In the redistribution, which took effect in 1885, County Tyrone was divided into four single-member constituencies; East Tyrone, Mid Tyrone, North Tyrone and South Tyrone.

Politics

The constituency electorate was predominantly Tory/Conservative during most of this period.

Catholics were excluded from qualifying as voters until 1793 and taking seats in Parliament until 1829 and there was a restrictive property based franchise. It was not until the electoral reforms which took effect in 1885 that most adult males became voters. See Catholic emancipation for further details.
