Crab meat

Crab meat or crabmeat is the meat found within a crab. It is used in many cuisines across the world, prized for its soft, delicate, sweet taste. Brown crab (Cancer pagurus), blue crabs (Callinectes sapidus), blue swimming crabs (Portunus pelagicus), red swimming crabs (Portunus haanii) are among the most commercially available species of crabmeat globally. In some fisheries, crab meat is harvested by declawing of crabs. This is the process whereby one or both claws of a live crab are manually pulled off and the animal is then returned to the water. The practice is defended because some crabs can naturally autotomise (shed) limbs and then about a year later after a series of moults, regenerate these limbs. It is argued that declawing therefore provides a sustainable fishery, however, declawing can lead to 47% mortality and negative effects on feeding behaviour. Furthermore, once separated from the body, the claws will start to degenerate—usually, crabs are cooked moments after capture.

Crab

Crabs are decapod crustaceans of the infraorder Brachyura, which typically have a very short projecting "tail" (abdomen) (Greek: βραχύς / brachys = short,οὐρά / οura = tail), usually entirely hidden under the thorax. They live in all the world's oceans, in fresh water, and on land, are generally covered with a thick exoskeleton and have a single pair of claws. Many other animals with similar names – such as hermit crabs, king crabs, porcelain crabs, horseshoe crabs and crab lice – are not true crabs.

Evolution

Crabs are generally covered with a thick exoskeleton, composed primarily of calcium carbonate, and armed with a single pair of chelae (claws). Crabs are found in all of the world's oceans, while many crabs live in fresh water and on land, particularly in tropical regions. Crabs vary in size from the pea crab, a few millimetres wide, to the Japanese spider crab, with a leg span of up to 4 metres (13 ft).

About 850 species of crab are freshwater, terrestrial or semi-terrestrial species; they are found throughout the world's tropical and semi-tropical regions. They were previously thought to be a monophyletic group, but are now believed to represent at least two distinct lineages, one in the Old World and one in the New World.

Crab (unit)

A Crab is a standard astrophotometrical unit for measurement of the intensity of Astrophysical X-ray sources. One Crab is defined as the intensity of the Crab Nebula at the corresponding X-ray photon energy.

The Crab Nebula, and the Crab Pulsar within it, is an intense space X-ray source. It is used as a standard candle in the calibration procedure of X-ray instruments in space. However, because of the Crab Nebula's variable intensity at different X-ray energies, conversion of the Crab to another units depends on the X-ray energy range of interest.

In the photon energy range from 2 to 10 keV, 1 Crab equals 2.4 · 10⁻⁸erg cm⁻²s⁻¹ = 15 keV cm⁻² s⁻¹ = 2.4 · 10⁻¹¹W m⁻². For energies greater than ~30 keV, the Crab Nebula becomes unsuitable for calibration purposes, as its flux can no longer be characterized by a single coherent model.

The unit mCrab, or milliCrab, is sometimes used instead of the Crab.

Crab (cipher)

In cryptography, Crab is a block cipher proposed by Burt Kaliski and Matt Robshaw at the first Fast Software Encryption workshop in 1993. Not really intended for use, Crab was developed to demonstrate how ideas from hash functions could be used to create a fast cipher.

Crab has an unusually large block size of 8192 bits. Its creators suggested using an 80-bit key, but the cipher could use any key size. The authors didn't specify an actual key schedule, only that the key is used to generate two large sets of subkeys: a permutation of the numbers 0 through 255, and an array of 2048 32-bit numbers. The block is divided into 256 32-bit subblocks, which are permuted at the beginning. Then the algorithm makes four passes over the data, each time applying one of four transformations adapted from MD5.

A brief note on the cryptanalysis of Crab is included in Markku-Juhani Saarinen's paper on block ciphers based on SHA-1 and MD5, published at FSE 2003. The author demonstrates a weakness in Crab that permits a distinguisher using no more than a dozen chosen plaintexts, and speculates that this can be converted into a full key-recovery attack using no more than 2¹⁶ chosen plaintexts. Such an attack would depend on the key schedule used.

Meat

Meat is animal flesh that is eaten as food. Humans are omnivorous, and have hunted and killed animals for meat since prehistoric times. The advent of civilization allowed the domestication of animals such as chickens, sheep, pigs and cattle, and eventually their use in meat production on an industrial scale.

Meat is mainly composed of water, protein, and fat, and is usually eaten together with other food. It is edible raw, but is normally eaten after it has been cooked and seasoned or processed in a variety of ways. Unprocessed meat will spoil or rot within hours or days as a result of infection with and decomposition by bacteria and fungi.

Most often, meat refers to skeletal muscle and associated fat and other tissues, but it may also describe other edible tissues such as offal.Meat is sometimes also used in a more restrictive sense – the flesh of mammalian species (pigs, cattle, lambs, etc.) raised and prepared for human consumption, to the exclusion of fish, other seafood, poultry or other animals.

List of Mortal Kombat characters

This is a list of playable characters from the Mortal Kombat fighting game series and the games in which they appear. The series takes place in a fictional universe composed of six realms, which were created by the Elder Gods. The Elder Gods created a fighting tournament called Mortal Kombat to reduce the wars between the realms. The first Mortal Kombat game introduces a tournament in which Earthrealm can be destroyed if it loses once again.

The Earthrealm warriors manage to defeat the champion Goro and tournament host Shang Tsung, but this leads Tsung to search for other ways to destroy Earthrealm. Since then, every game features a new mortal who wishes to conquer the realms, therefore violating the rules of Mortal Kombat. By Mortal Kombat: Deception, most of the main characters had been killed by Shang Tsung and Quan Chi (neither of whom were playable in the game), but by Mortal Kombat: Armageddon all of them return.
