Chupacabra

The chupacabra or chupacabras (Spanish pronunciation: [tʃupaˈkaβɾas], literally "goat-sucker") is a legendary cryptid rumored to inhabit parts of the Americas, with the first sightings reported in Puerto Rico. The name comes from the animal's reported habit of attacking and drinking the blood of livestock, especially goats.

Physical descriptions of the creature vary. It is purportedly a heavy creature, the size of a small bear, with a row of spines reaching from the neck to the base of the tail.

Eyewitness sightings have been claimed as early as 1995 in Puerto Rico, and have since been reported as far north as Maine, and as far south as Chile, and even being spotted outside the Americas in countries like Russia and the Philippines, but many of the reports have been disregarded as uncorroborated or lacking evidence. Sightings in northern Mexico and the southern United States have been verified as canids afflicted by mange. According to biologists and wildlife management officials, the chupacabra is an urban legend.

Cryptid Hunters

Cryptid Hunters is a 2005 young adult science fiction novel by Roland Smith; it follows the adventures of thirteen-year-old cousins Grace Wolfe and Marty O'Hara, who go to live with their Uncle Wolfe, an anthropologist on a remote island, who is searching for cryptids, which are animals thought to be extinct or not to exist. His rival, Blackwood, a popular animal collector, tries to acquire an alleged dinosaur egg from Wolfe, and the twins get involved in the conflict which reveals a convoluted family history. The novel was nominated for several library awards and book lists, which include Hawaii's 2008 Nene Recommended Book List, the Texas Library Association's 2007-2008 Lone Star Reading List, and Third Place for the Missouri Association of School Librarians' Mark Twain Readers Award. Smith has written three sequels called Tentacles, Chupacabra, and Mutation.

Plot

Marty and Grace O'Hara are thirteen-year-old twins with differing personalities; Marty is a "mischief maker" with a photographic memory and is very curious; Grace is very intelligent but has a "healthy dose of phobias". They have been attending boarding school in Switzerland. Their parents are photojournalists, however, one day they go missing in the Amazon jungle from a helicopter crash. The twins are consequently sent to live with their uncle, Travis Wolfe, an anthropologist who lives on a private island called Cryptos, off the coast of the state of Washington.

Rolling-element bearing

A rolling-element bearing, also known as a rolling bearing, is a bearing which carries a load by placing rolling elements (such as balls or rollers) between two bearing rings called races. The relative motion of the races causes the rolling elements to roll with very little rolling resistance and with little sliding.

One of the earliest and best-known rolling-element bearings are sets of logs laid on the ground with a large stone block on top. As the stone is pulled, the logs roll along the ground with little sliding friction. As each log comes out the back, it is moved to the front where the block then rolls on to it. It is possible to imitate such a bearing by placing several pens or pencils on a table and placing an item on top of them. See "bearings" for more on the historical development of bearings.

A rolling element rotary bearing uses a shaft in a much larger hole, and cylinders called "rollers" tightly fill the space between the shaft and hole. As the shaft turns, each roller acts as the logs in the above example. However, since the bearing is round, the rollers never fall out from under the load.

Cage (graph theory)

In the mathematical area of graph theory, a cage is a regular graph that has as few vertices as possible for its girth.

Formally, an (r,g)-graph is defined to be a graph in which each vertex has exactly r neighbors, and in which the shortest cycle has length exactly g. It is known that an (r,g)-graph exists for any combination of r ≥ 2 and g ≥ 3. An (r,g)-cage is an (r,g)-graph with the fewest possible number of vertices, among all (r,g)-graphs.

If a Moore graph exists with degree r and girth g, it must be a cage. Moreover, the bounds on the sizes of Moore graphs generalize to cages: any cage with odd girth g must have at least

vertices, and any cage with even girth g must have at least

vertices. Any (r,g)-graph with exactly this many vertices is by definition a Moore graph and therefore automatically a cage.

There may exist multiple cages for a given combination of r and g. For instance there are three nonisomorphic (3,10)-cages, each with 70 vertices : the Balaban 10-cage, the Harries graph and the Harries–Wong graph. But there is only one (3,11)-cage : the Balaban 11-cage (with 112 vertices).

The Cage (ballet)

The Cage is a ballet made by New York City Ballet ballet master Jerome Robbins to Stravinsky's Concerto in D for string orchestra, also known as the "Basel Concerto", which he was commissioned to compose on the twentieth anniversary of the chamber orchestra Basler Kammerorchester; it notably shifts between D major and minor. The premiere took place on Sunday, 10 June 1951 at the City Center of Music and Drama, New York, with décor by Jean Rosenthal, costumes by Ruth Sobatka and lighting by Jennifer Tipton. It was danced as part of City Ballet's 1982 Stravinsky Centennial Celebration.
