Bear

Bears are mammals of the family Ursidae. Bears are classified as caniforms, or doglike carnivorans, with the pinnipeds being their closest living relatives. Although only eight species of bears are extant, they are widespread, appearing in a wide variety of habitats throughout the Northern Hemisphere and partially in the Southern Hemisphere. Bears are found on the continents of North America, South America, Europe, and Asia.

Common characteristics of modern bears include large bodies with stocky legs, long snouts, shaggy hair, plantigrade paws with five nonretractile claws, and short tails. While the polar bear is mostly carnivorous, and the giant panda feeds almost entirely on bamboo, the remaining six species are omnivorous with varied diets.

With the exception of courting individuals and mothers with their young, bears are typically solitary animals. They are generally diurnal, but may be active during the night (nocturnal) or twilight (crepuscular), particularly around humans. Bears possess an excellent sense of smell and, despite their heavy build and awkward gait, are adept runners, climbers, and swimmers. In autumn, some bear species forage large amounts of fermented fruits, which affects their behaviour. Bears use shelters, such as caves and burrows, as their dens; most species occupy their dens during the winter for a long period (up to 100 days) of sleep similar to hibernation.

USS Bear (1874)

The SS Bear was a dual steam-powered and sailing ship built with six inch (15.2 cm) thick sides which had a long life in various cold-water and ice-filled environs. She was a forerunner of modern icebreakers and had an exceptionally diverse service life. According to the United States Coast Guard official website, Bear is described as "probably the most famous ship in the history of the Coast Guard."

Built in Scotland in 1874 as a steamer for sealing, she was owned and operated out of Newfoundland for ten years. In the mid-1880s, she took part in the search for the Greely Expedition. Captained by Michael Healy of the United States Revenue Cutter Service (later part of the U.S. Coast Guard), she worked the 20,000 mile coastline of Alaska. She later assisted with relief efforts after the 1906 San Francisco earthquake.

Her services also included the second expedition of Admiral Richard E. Byrd to Antarctica, and again to the southernmost continent in 1941 to evacuate Americans at the beginning of World War II. She later served in patrol duty off the coast of Greenland for the United States Navy. Between some of these missions, she was a museum ship in Oakland, California and starred in the 1930 film version of Jack London's The Sea-Wolf.

Flatline

A flatline is an electrical time sequence measurement that shows no activity and therefore, when represented, shows a flat line instead of a moving one. It almost always refers to either a flatlined electrocardiogram, where the heart shows no electrical activity (asystole), or to a flat electroencephalogram, in which the brain shows no electrical activity (brain death). Both of these specific cases are involved in various definitions of death.

Cardiac flatline

A cardiac flatline is also called asystole. It can possibly be generated by malfunction of the electrocardiography device, but it is recommended to first rule out a true asystole because of the emergency of such condition.

When a patient displays a cardiac flatline, the treatment of choice is cardiopulmonary resuscitation and injection of vasopressin (epinephrine and atropine are also possibilities). Successful resuscitation is generally unlikely and is inversely related to the length of time spent attempting resuscitation. Defibrillation is not recommended, despite commonly appearing on medical dramas as a remedy for asystole, but can be used for certain other causes of cardiac arrest.

Flatline (album)

Flatline is the eighth album released by MC Breed. It was released on September 23, 1997 for Wrap Records and was produced by MC Breed, Jazze Pha, Ant Banks, The D.O.C., Preston Crump and Erotic D. Though it gained mostly positive reviews, the album only peaked at #48 on the Top R&B/Hip-Hop Albums. This was Breed's last album for Wrap Records.
