Cardiopulmonary resuscitation

Cardiopulmonary resuscitation, commonly known as CPR, is an emergency procedure performed in an effort to manually preserve intact brain function until further measures are taken to restore spontaneous blood circulation and breathing in a person who is in cardiac arrest. It is indicated in those who are unresponsive with no breathing or abnormal breathing, for example, agonal respirations.

According to the International Liaison Committee on Resuscitation guidelines, CPR involves chest compressions for adults between 5 cm (2.0 in) and 6 cm (2.4 in) deep and at a rate of at least 100 to 120 per minute. The rescuer may also provide breaths by either exhaling into the subject's mouth or nose or using a device that pushes air into the subject's lungs. This process of externally providing ventilation is termed artificial respiration. Current recommendations place emphasis on high-quality chest compressions over artificial respiration; a simplified CPR method involving chest compressions only is recommended for untrained rescuers. In children only doing compressions may result in worse outcomes.

Darkness

Darkness, the polar opposite to brightness, is understood to be an absence of visible light. It is also the appearance of black in a colored space.

Humans are unable to distinguish color when either light or darkness predominate. In conditions of insufficient light, perception is achromatic and ultimately, black.

The emotional response to darkness has generated metaphorical usages of the term in many cultures.

Scientific

Perception

The perception of darkness differs from the mere absence of light due to the effects of after images on perception. In perceiving, the eye is active, and that part of the retina that is unstimulated produces a complementary afterimage.

Physics

In terms of physics, an object is said to be dark when it absorbs photons, causing it to appear dim compared to other objects. For example, a matte black paint does not reflect much visible light and appears dark, whereas white paint reflects much light and appears bright. For more information see color.

Light cannot be absorbed without limit. According to the principle of the conservation of Energy, energy cannot be created or destroyed; it can only be converted from one type to another. Consequently, most objects that absorb visible light reemit it as heat. So, although an object may appear dark, it is likely bright at a frequency that humans cannot perceive. For more information see thermodynamics.

Darkness (2002 film)

Darkness is a 2002 Spanish-American horror film directed by Jaume Balagueró and starring Anna Paquin, Lena Olin, Iain Glen, Giancarlo Giannini and Fele Martínez. The film was produced by Julio Fernández and Brian Yuzna. The film's plot follows an American family who moves into a house in the Spanish countryside where six children disappeared during an occult ritual forty years before; the teenage daughter and young son of the family are subjected to increasing disturbances in the house.

The film premiered in Spain on October 3, 2002, and was released in theaters across the country eight days later on October 11, 2002. It was later sold to Miramax Films for American distribution in 2003, but ended up being put on hiatus for over a year; it was eventually released in theaters in an edited, PG-13-rated cut in the United States on December 25, 2004.

Plot

Forty years after an unfinished occult ritual resulted in the disappearance of six young children, an American family has moved into a never-before inhabited house in Spain. The mother, Maria (Olin), wants to get the place in order, while the father, Mark (Glen), goes to work, and their children, teenager Regina (Paquin) and her younger brother Paul (Enquist), try to settle into their daily routines.

The Darkness (video game)

The Darkness is a first-person shooter video game developed by Starbreeze Studios and published by 2K Games for the PlayStation 3 and Xbox 360. The game was released in June 2007 in North America and Europe and is based on the comic book of the same name. A sequel titled The Darkness II was released in February 2012.

Plot

The player takes the role of Jackie Estacado (voiced by Kirk Acevedo), with the story presented as a future-narrative on the present events observed by the player. On the eve of his 21st birthday, Jackie is targeted for assassination by "Uncle" Paulie Franchetti (voiced by Dwight Schultz), a New York Mafia boss, following a failed task to retrieve money for the latter. While hiding in a cemetery bathroom, the Darkness (voiced by Mike Patton), an ancient demonic force that has inhabited his family for several generations, awakens within Jackie and slaughters the remaining mobsters, with the benefit of Jackie becoming the possessor of seemingly unholy demonic abilities that work only in the dark. Using these powers, Jackie proceeds to destroy Paulie's business by killing his biggest drug peddler, Dutch Oven Harry (voiced by Richard Leighton), and burning down the slaughterhouse where he stores his money. In retribution, Paulie and his main enforcer, Captain Eddie Shrote (voiced by Jim Mathers) of the New York City Police Department, kidnap Jackie's girlfriend Jenny Romano (voiced by Lauren Ambrose). They take her to the orphanage where Jackie and Jenny grew up and murder her in front of a powerless Jackie, who is unable to save Jenny due to the Darkness deliberately restraining him.
