The real facts about Neptune
Neptune's blue color is mainly the result of absorption of red light by methane in the atmosphere but there is a number of additional as-yet-unidentified chromophore which gives the clouds their rich blue tint. Like Jupiter and Saturn, Neptune has an inner heat source -- it radiates more than, twice as much energy as it receives from the Sun.
Neptune also has rings. Earth-based observations showed just faint arcs rather than complete rings, but Voyager 2's images showed them to be entire rings with bright clumps. One of the rings looks to have a curious twisted structure (right). Like Uranus and Jupiter, Neptune's rings are extremely dark but their composition is unknown.
Neptune's rings have been noted names: the outermost is Adams (which contains three important arcs now named Liberty, Equality and Fraternity), next is an unnamed ring co-orbital with Galatea, then Leverrier (whose outer extensions are called Lassell and Arago), and lastly the faint but broad Galle. Neptune's magnetic field is, like Uranus', oddly oriented and most likely generated by motions of conductive material (probably water) in its middle layers.

The real facts about Pluto
Pluto is safe in a 3:2 resonance with Neptune; i.e. Pluto's orbital period is just 1.5 times longer than Neptune's. Its orbital inclination is as well much higher than the other planets'. Thus though it looks that Pluto's orbit crosses Neptune's, it actually doesn't and they will never collide. Pluto's composition is unidentified, but its density (about 2 gm/cm3) indicates that it is almost certainly a mixture of 70% rock and 30% water ice much like Triton. The bright areas of the surface appear to be covered with ices of nitrogen with lesser amounts of (solid) methane, ethane and carbon monoxide. The composition of the darker areas of Pluto's surface is unidentified but may be due to primordial organic material or photochemical reactions driven by cosmic rays.
Little is recognized about Pluto's atmosphere, but it perhaps consists primarily of nitrogen with some carbon monoxide and methane. It is very tenuous, the surface pressure being only some microbars. Pluto's atmosphere can exist as a gas only when Pluto is near its perihelion; for the greater part of Pluto's long year, the atmospheric gases are frozen into ice. Close to perihelion, it is likely that some of the atmosphere escapes to space possibly even interacting with Charon. NASA mission planners want to appear at Pluto while the atmosphere is still unfrozen.

Butter chicken
It is a dish prepared by marinating a chicken overnight in a yoghurt and spice mixture usually together with garam masala, ginger, lemon or lime, pepper, coriander, cumin, turmeric, chilli, methi and garlic. It is in various ways like to chicken tikka masala. The chicken is then roasted or dry as a bone.

Fresh skin-care tips
Fresh fruit and vegetables are especially high in acids. If you apply anything to your skin and encounter a burning sensation, take out immediately and apply cool water.If you are in the care of a dermatologist and on acne medications, please consult with your physician first.

Asian Paradise Flycatcher
The Asian glory Flycatcher breeds from Turkestan to Manchuria. It is wandering, wintering in tropical Asia. There are resident populations further south, for example in southern India and Sri Lanka, so both visiting migrants and the in the vicinity reproduction subspecies take place in these areas in winter.
This species is typically originated in thick forests and other well-wooded habitats. Three or four eggs are laid in a cup shell in a tree.
The adult male Asian Paradise Flycatcher is about 20 cm long, but the long tail streamers double this. It has a black crested head, stale joke upperparts and pale grey underparts.
By their second year, the males of the wandering Indian race T. p. paradisi begin to obtain white feathers. By the third year, the male plumage is totally white, other than the black head. Males of the sedentary Sri Lankan race T. p. ceylonensis are forever stale joke.
The female of all races resembles the stale joke male, but has a grey throat, minor peak and lacks the tail streamers.

Mainframes
The term originated during the early 1970s with the introduction of smaller, fewer complex computers such as the DEC PDP-8 and PDP-11 series, which became known as minicomputers or just minis. The industry/users then coined the term "mainframe" to describe bigger, earlier types (previously known simply as "computers").

Lighthouse of Alexandria
With a height variously estimated at between 115 and 150 meters (383 - 450 ft) it was among the tallest man-made structures on Earth for many centuries, and was recognized as one of the Seven Wonders of the World by Antipater of Sidon. It was the third tallest building after the two Great Pyramids (of Khufu and Khafra) for its whole life. Some scientists approximate a much taller height exceeding 180 metres that would make the tower the tallest building up to the 14th century.

Asia
Chiefly in the eastern and northern hemispheres, Asia is conventionally defined as part of the landmass of Africa-Eurasia – with the western portion of the latter occupied by Europe – lying east of the Suez Canal, east of the Ural Mountains, and south of the Caucasus Mountains and the Caspian and Black Seas. It is surrounded to the east by the

Management information system
Management Information Systems (MIS) is a general name for the educational discipline casing the application of people, technologies, and procedures —together called information systems — to solve business problems. MIS are distinctive from normal information systems in that they are used to evaluate other information systems applied in operational activities in the organization. Rationally, the term is commonly used to refer to the group of information management methods attached to the automation or support of human decision making, e.g. Decision Support Systems, Expert systems, and Executive information system

Accumulator
The canonical example for accumulator use is adding a list of numbers. The accumulator is initially set to zero, then each number in spin is added to the value in the accumulator. Only when all numbers have been added is the result seized in the accumulator written to main memory or to another, non-accumulator, CPU register.

Superscalar
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 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 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 .

Shrimp fishery
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
