Krill fishery

Krill fishery is the commercial fishery of krill, small shrimp-like marine animals that live in the oceans world-wide. Estimates for how much krill there is vary wildly, depending on the methodology used. They range from 125–725 million tonnes of biomass globally. The total global harvest of krill from all fisheries amounts to 150 – 200,000 tonnes annually, mainly Antarctic krill (Euphausia superba) and North Pacific krill (E. pacifica).

Krill are rich in protein (40% or more of dry weight) and lipids (about 20% in E. superba). Their exoskeleton amounts to some 2% of dry weight of chitin. They also contain traces of a wide array of hydrolytic enzymes such as proteases, carbohydrases, nucleases and phospholipases, which are intense in the digestive gland in the cephalothorax of the krill.

Most krill is used as aquaculture feed and fish bait; other uses comprise livestock or pet foods. Only a small percentage is prepared for human consumption. Their enzymes are interesting for medical applications, an expanding sector since the early 1990s.

Shrimp fishery

A shrimp fishery is a fishery directed toward harvesting either shrimp or prawns. Fisheries do not usually differentiate between the two taxa, and the terms are used interchangeably. This article therefore refers to the catching of either shrimp or prawns.

A number of the larger species, including the Atlantic white shrimp (Penaeus setiferus), are caught commercially and used for food. Recipes utilizing shrimp form part of the cuisine of many cultures: examples include jambalaya, okonomiyaki, poon choi, bagoong, Kerala and scampi.
Preparing shrimp for consumption usually involves removing the shell, tail, and "sand vein". As with other seafood, shrimp is high in calcium, protein and low in food energy.
Shrimp and prawns are versatile ingredients, and are often used as an accompaniment to fried rice. Common methods of preparation comprise baking, boiling and frying. As stated in the movie Forrest Gump

A ghost is typically defined as the apparition of a deceased person, regularly similar in appearance to that person, and encountered in places he or she frequented, or in association with the person's former belongings. The word "ghost" may also refer to the spirit or soul of a deceased person, or to any spirit or demon.Ghosts are often connected with haunting, which is, according to the Parapsychological Association, "the more or less regular occurrence of paranormal phenomena associated with a particular locality (especially a building) and typically attributed to the activities of a discarnate entity; the phenomena may comprise apparitions, poltergeist disturbances, cold drafts, sounds of steps and voices, and various odours.
Ghosts are controversial phenomena. According to a poll conducted in 2005 by the Gallup Organization, about 32% of Americans consider in the existence of ghosts.The term ghost has been replaced by apparition in parapsychology, because the word ghost is deemed inadequately precise.

MIPS-Microprocessor without Interlocked Pipeline Stages

MIPS designs are used in a lot of embedded systems such as the Series2 TiVo, Windows CE devices, Cisco routers, and video game consoles similar to the Nintendo 64 and Sony PlayStation, PlayStation 2, and PlayStation Portable handheld system. Until late 2006 they were also used in a lot of SGI's computer products.

Near the beginning MIPS architectures were 32-bit implementations, while later versions were 64-bit implementations. Multiple revisions of the MIPS instruction set exist, including MIPS I, MIPS II, MIPS III, MIPS IV, MIPS V, MIPS32, and MIPS64. The current revisions are MIPS32 (for 32-bit implementations) and MIPS64 for (64-bit implementations). MIPS32 and MIPS64 define a control register set as well as the instruction set. Several "add-on" extensions are also available, including MIPS-3D which is a simple set of floating-point SIMD orders dedicated to common 3D tasks, MDMX which is a more extensive integer SIMD instruction set using the 64-bit floating-point registers, MIPS16e which adds density to the instruction stream to make programs take up less room, and the recent addition of MIPS MT, new multithreading additions to the system similar to Hyper Threading in the Intel's Pentium 4 processors.

Snake River

The Snake River is a river in the western part of the United States. The Snake River is 1,038 miles in length, and is the Columbia River's main branch. The Lewis and Clark expedition was the first major U.S. investigation of the river, and the Snake was once known as the Lewis River.

The Snake originates near the Continental Divide in Yellowstone National Park in NW Wyoming and flows south to Jackson Lake in Grand Teton National Park and long-ago the town of Jackson. The river flows down Snake River Canyon, then enters Idaho at the Palisades Reservoir and joins with the Henrys Fork River near Rigby. Note: inhabitants of eastern Idaho generally call the Snake prior to this joining the "South Fork of the Snake", individual it from the Henrys Fork.
Tributaries of the Snake contain the Henrys Fork River, the Boise River, the Salmon River, and the Clearwater River.

The Snake River's lots of hydroelectric power plants are a major source of electricity in the region. Its watershed provides irrigation for various projects, including the Minidoka, Boise, Palisades, and Owyhee projects by the U.S. Bureau of Reclamation, as well as a diversity of private projects such as at Twin Falls. However, these dams have also had an adverse environmental effect on wildlife, most notably on wild salmon migrations.
The Snake runs through a number of gorges, including one of the deepest in the world, Hells Canyon, with a greatest depth of 7,900 feet.
The name "Snake" possibly derived from an S-shaped sign which the Shoshone Indians made with their hands to mimic swimming salmon variation names of the river have included:

Music is an art form that involves what are sometimes organised sounds and silence, although in some forms of 20th century aleatoric, and certainly improvisational music, as well as most Eastern traditions such as Gamelou, this is not the case. It is expressed in terms of pitch (which includes melody and harmony), rhythm (which includes tempo and meter), and the quality of sound .Music may also engage generative forms in time through the building of patterns and combinations of natural stimuli, principally sound. Music may be used for artistic or aesthetic, communicative, entertainment, ceremonial or religious purposes and by many composers purly as an academic instrument for study.The description of what constitutes music varies according to culture and social context, with varied interpretations of the term being accepted under sub-genres of the art. Within "the arts", music can be classified as a performing art, a fine art, or an auditory art form.

Columbia River

The Columbia River is a river located in British Columbia and the Pacific Northwest of the United States. It is the biggest river in volume flowing into the Pacific Ocean from North America, and the second largest in the United States. It is the largest hydroelectric power producing river in North America. From its headwaters to the Pacific Ocean it flows 1,270 miles, and drains 258,000 square
