Philadelphia

Philadelphia (/ˌfɪləˈdɛlfiə/) is the largest city in the Commonwealth of Pennsylvania and the fifth-most-populous in the United States, with an estimated population in 2014 of 1,560,297. In the Northeastern United States, at the confluence of the Delaware and Schuylkill River, Philadelphia is the economic and cultural anchor of the Delaware Valley, a metropolitan area home to 7.2 million people and the eighth-largest combined statistical area in the United States.

In 1682, William Penn founded the city to serve as capital of the Pennsylvania Colony. Philadelphia played an instrumental role in the American Revolution as a meeting place for the Founding Fathers of the United States, who signed the Declaration of Independence in 1776 and the Constitution in 1787. Philadelphia was one of the nation's capitals in the Revolutionary War, and served as temporary U.S. capital while Washington, D.C., was under construction. In the 19th century, Philadelphia became a major industrial center and railroad hub that grew from an influx of European immigrants. It became a prime destination for African-Americans in the Great Migration and surpassed two million occupants by 1950.

Philadelphia (film)

Philadelphia is a 1993 American drama film and one of the first mainstream Hollywood films to acknowledge HIV/AIDS, homosexuality, and homophobia. It was written by Ron Nyswaner, directed by Jonathan Demme and stars Tom Hanks and Denzel Washington.

Hanks won the Academy Award for Best Actor for his role as Andrew Beckett in the film, while the song "Streets of Philadelphia" by Bruce Springsteen won the Academy Award for Best Original Song. Nyswaner was also nominated for the Academy Award for Best Original Screenplay, but lost to Jane Campion for The Piano.

Plot

Andrew Beckett (Tom Hanks) is a Senior Associate at the largest corporate law firm in Philadelphia. Beckett hides his homosexuality and his status as an AIDS patient from the other members of the law firm. On the day Beckett is assigned the firm's newest and most important case, a partner in the firm notices a lesion on Beckett's forehead. Although Beckett attributes the lesion to a racquetball injury, it is actually due to Kaposi's Sarcoma, a form of cancer marked by multiple tumors on the lymph nodes and skin.

Philadelphia (magazine)

Philadelphia (usually called "Philadelphia magazine" and often incorrectly written as "Philadelphia Magazine" or referred to by the nickname "Phillymag") is a regional monthly magazine published in Philadelphia, Pennsylvania by the Lipson family of Philadelphia and its company, Metrocorp.

One of the oldest magazines of its kind, it was first published in 1908 by the Trades League of Philadelphia. S. Arthur Lipson bought the paper in 1946.

Dominican Order

The Order of Preachers (Latin: Ordo Praedicatorum, hence the abbreviation OP used by members), more commonly known after the 15th century as the Dominican Order or Dominicans, is a Roman Catholic religious order founded by the Spanish priest Saint Dominic de Guzman in France and approved by Pope Honorius III (1216–27) on 22 December 1216. Membership in this "mendicant" Order includes friars, nuns, active sisters, and lay or secular Dominicans (formerly known as tertiaries, though recently there has been a growing number of Associates, who are unrelated to the tertiaries) affiliated with the Order.

Founded to preach the Gospel and to combat heresy, the teaching activity of the order and its scholastic organization placed the Preachers in the forefront of the intellectual life of the Middle Ages. The order is famed for its intellectual tradition, having produced many leading theologians and philosophers. The Dominican Order is headed by the Master of the Order, who is currently Bruno Cadoré. Members of the order generally carry the letters O.P., standing for Ordinis Praedicatorum, meaning of the Order of Preachers, after their names.

Allotropes of oxygen

There are several known allotropes of oxygen. The most familiar is molecular oxygen (O₂), present at significant levels in Earth's atmosphere and also known as dioxygen or triplet oxygen. Another is the highly reactive ozone (O₃). Others include:

Atomic oxygen

Atomic oxygen, denoted O(³P), O(3P) or O((3)P), is very reactive, as the single atoms of oxygen tend to quickly bond with nearby molecules; on Earth's surface it does not exist naturally for very long, though in outer space, the presence of plenty of ultraviolet radiation results in a low Earth orbit atmosphere in which 96% of the oxygen occurs in atomic form.

Dioxygen

The common allotrope of elemental oxygen on Earth, O
2, is generally known as oxygen, but may be called dioxygen or molecular oxygen to distinguish it from the element itself. Elemental oxygen is most commonly encountered in this form, as about 21% (by volume) of Earth's atmosphere. Dioxygen can occur in metastable states, called singlet oxygen; in contrast, the ground state is known as triplet oxygen.
