Superscalar

A superscalar CPU architecture implements a form of parallelism called Instruction-level parallelism within a solitary processor. It thereby allows faster CPU throughput than would otherwise be possible at the same clock rate. A superscalar architecture executes more than one instruction during a single pipeline stage by pre-fetching several instructions and at the same time dispatching them to redundant functional units on the processor.

History

Seymour Cray's CDC 6600 from 1965 is often mentioned as the first superscalar plan. The Intel i960CA and the AMD 29000-series 29050 microprocessors were the first commercial single-chip superscalar microprocessors. RISC CPUs like these brought the superscalar idea to micro computers because the RISC design results in a simple core, allowing straightforward instruction send off and the inclusion of multiple functional units on a single CPU in the inhibited design rules of the time. This was the reason that RISC designs were faster than CISC designs through the 1980s and into the 1990s.

Neem oil

Neem oil is a vegetable oil pressed from the fruits and seeds of Neem, an evergreen tree which is endemic to the Indian sub-continent and has been introduced to many other areas in the tropics. It is perhaps the most significant of the commercially available products of neem.
Neem oil is typically light to dark brown, bitter and has a rather strong odour that is said to join the odours of peanut and garlic. It comprises mainly triglycerides and large amounts of triterpenoid compounds, which are in charge for the bitter taste. It is hydrophobic in nature and in order to emulisify it in water for application purposes, it must be formulated with suitable surfactants.
Neem oil also contains steroids and a plethora of triterpenoids of which Azadirachtin is the most well known and studied. The Azadirachtin content of Neem Oil varies from 300ppm to over 2000ppm depending on the quality of the neem seeds compressed.

Swan

Swans are large water birds of the family Anatidae, which also includes geese and ducks. Swans are grouped with the intimately related geese in the subfamily Anserinae where they form the tribe Cygnini. Sometimes, they are considered a distinct subfamily, Cygninae.

Swans typically mate for life, though "divorce" does sometimes occur, mainly following nesting failure. The number of eggs in each clutch is between 3–8.
The word is derived from Old English swan, akin to German Schwan, in turn derived from Indo-European root *swen (to sound, to sing), whence Latin derives sonus (sound). Young swans are known as cygnets, from the Latin word for swan, cygnus. An adult male is a cob, from Middle English cobbe; an adult female is a pen .

Ice

Ice is the name given to any one of the 14 known solid phases of water. Though in non-scientific contexts, it usually describes ice Ih, which is the most abundant of these phases. It is a crystalline solid, which can appear transparent or an opaque bluish-white color depending on the presence of impurities such as air. The addition of other materials such as soil may further alter appearance. The most common phase transition to ice Ih occurs when liquid water is cooled below 0 °C (273.15 K, 32 °F) at standard atmospheric pressure. However, it can also deposit from a vapor with no intervening liquid phase such as in the formation of frost. Ice appears in varied forms such as hail, ice cubes, and glaciers. It plays an important role with many meteorological phenomena. The ice caps of the polar regions are of significance for the global climate and particularly the water cycle.

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

Rose

A rose is a flowering shrub of the genus Rosa, and the flower of this shrub. There are more than a hundred classes of wild roses, all from the northern hemisphere and typically from temperate regions. The species form a group of normally prickly shrubs or climbers, and sometimes trailing plants, reaching 2–5 m tall, hardly ever reaching as high as 20 m by climbing over other plants.
Rose hips are sometimes eaten, mostly for their vitamin C content. They are typically pressed and filtered to make rose-hip syrup, as the fine hairs surrounding the seeds are unpleasant to eat. They can also be used to create herbal tea, jam, jelly and marmalade.

Industrial metal

Industrial metal is a musical genre which draws elements from industrial music and heavy metal music. Industrial metal music is typically centered around metal guitar riffs and industrial synthesizer/sequencer lines, heavily distorted, very low pitched guitars, as well as harsh vocals, but in some instances can have clean vocals. This term is used quite loosely, telling everything from industrial bands sampling metal riffs to heavy metal groups augmented with sequencers. Industrial metal encompasses industrial subgenres such as aggro-industrial and coldwave and often overlaps some elements of nu-metal and post-punk.

It is difficult to distinguish many industrial metal artists and industrial rock because both genres leave much room for ingenuity and creativity. By convention, all industrial metal artists may be more vaguely described as industrial rock as well, but not all industrial rock artists are properly described as industrial metal. The general rule of thumb is the speed and "crunchiness" of the guitars. If the guitars are fast and heavily distorted, it is likely industrial metal.
