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.

Pruning

Pruning in landscaping and farming is the practice of removing diseased, non-productive, or otherwise unwanted portions from a plant. The purpose of pruning is to shape the plant by controlling or directing plant growth, to maintain the health of the plant, or to increase the yield or quality of flowers and fruits. Proper pruning is as much a skill as it is an art, since badly pruned plants can become unhealthy or grow in undesirable ways.

Proponents of pruning, both gardeners and orchardists, often argue that it improves the health of the plant and makes sturdier structure, often referred to as the scaffold; opponents consider that pruning harms plants' "natural" forms.

Cotton

Cotton is a soft fibre that grows around the seeds of the cotton plant , a shrub native to tropical and subtropical regions around the world, with the Americas, India, and Africa. However, virtually all of the commercial cotton grown today worldwide is grown from varieties of the native American species Gossypium hirsutum and Gossypium barbadense. The fibre is most often spun into thread and used to make a soft, breathable textile, which is the most widely used natural-fibre cloth in clothing today. The English name derives from the Arabic word al qutun, meaning "cotton fiber".
Cotton fibre, once it has been processed to remove seeds and traces of wax, protein, etc., consists of nearly pure cellulose, a natural polymer. Cotton manufacture is very efficient, in the sense that ten percent or less of the weight is lost in following processing to convert the raw cotton bolls into pure fibre. The cellulose is arranged in a way that gives cotton fibres a high degree of strength, durability, and absorbency. Each fibre is made up of twenty to thirty layers of cellulose coiled in a neat series of natural springs. When the cotton boll is opened, the fibres dry into flat, twisted, ribbon-like shapes and become kinked together and interlocked. This interlocked form is ideal for spinning into a fine yarn.

Goldfish

The goldfish, Carassius auratus, was one of the earliest fish to be domesticated, and is still one of the most usually kept aquarium fish and water gardens. A comparatively small member of the carp family ,which also includes the koi carp and the crucian carp, the goldfish is a domesticated version of a dark-gray/brown carp native to East Asia that was introduced to Europe in the late 17th century. The mutation that gave rise to the goldfish is also known from other cyprinid species, such as common carp and tench. Goldfish may grow to a maximum length of 23 inches (59 cm) and a maximum weight of 9.9 pounds (4.5 kg), although this is rare; few goldfish reach even half this size. In optimal conditions, goldfish may live more than 20 years (the world record is 49 years), but most household goldfish generally live only six to eight years, due to being kept in bowls.A group of goldfish is known as a troubling.

Watercraft

A watercraft is a vehicle, vessel or craft designed to move across water for pleasure, recreation, physical exercise, commerce, transport of people and goods, and military missions. It is resulting from the term "craft" which was used as term to describe all types of water going vessels. Most watercraft would be described as either a ship or a boat. However, there are a number of craft which many people would consider neither a ship nor a boat, such as: canoes, kayaks, rafts, barges, catamarans, hydrofoils, windsurfers, surfboards (when used as a paddle board), underwater robots, torpedos and jet skis.

Coppicing

Coppicing is a conventional method of woodland organization in which young tree stems are cut down to a low level. In subsequent growth years, many new shoots will come out and after a number of years the cycle begins again and the coppiced tree, or stool, is ready to be harvested again.
Typically a coppice woodland is harvested in sections, on a rotation. In this way each year a crop is available. This has the side-effect of as long as a rich variety of habitats, as the woodland always has a range of dissimilar aged stools growing in it. This is helpful for biodiversity. The cycle length depends upon the species cut, the local custom, and the use to which the product is put. Birch can be coppiced for faggots on a 3- or 4-year cycle, whereas oak can be coppiced over a 50-year cycle for poles or firewood.

Ras malai

Ras Malai is a sweet dish found in the Indian subcontinent consisting of sugary, cream to yellow-colored balls or flattened balls of cottage or ricotta cheese soaked in sweetened, thickened, creamy milk.The milk is flavoured with pistachios, saffron, and rosewater.

Rasmalai originated somewhere in the coastal parts of the Indian state of Orissa. Sometimes shown as Rassmalai . or Ras Malai
