Saturn

Saturn (pronounced /'sæt?n/) is the sixth planet from the Sun and the second largest planet in the Solar System, after Jupiter. Along with the planets Jupiter, Uranus, Neptune it is classify as a gas giant (also known as a Jovian planet, after the planet Jupiter). It was named after the Roman god Saturnus, equate to the Greek Kronos (the Titan father of Zeus) and the Babylonian Ninurta. Saturn's sign represents the god's sickle (Unicode: ?), The day in the week Saturday gets its name from the planet.

The planet Saturn is calm of hydrogen, with small proportions of helium and trace elements. The interior consists of a small core of rock and ice, bounded by a thick layer of metallic hydrogen and a gaseous outer layer. The outer atmosphere is normally bland in appearance, although long-lived features can appear. Wind speeds on Saturn can reach 1,800 km/h, considerably faster than those on Jupiter. Saturn has a planetary magnetic field intermediate in strength among that of Earth and the more powerful field around Jupiter.

Grapefruit

The grapefruit is a subtropical citrus tree grown for its fruit which was initially named the "forbidden fruit" of Barbados.
These evergreen trees are frequently found at around 5-6 m tall, even though they can reach 13-15 m. The leaves are shady green, long up to 150 mm and thin. It produces 5 cm fair four-petalled flowers. The fruit is yellow-skinned, mainly oblate and ranges in diameter from 10-15 cm. The flesh is segmented and acidic, unreliable in color depending on the cultivars, which include white, pink and red pulps of varying sweetness. The 1929 US Ruby Red (of the Red blush variety) has the first grapefruit patent.
The fruit has only become popular from the late 19th century; before that it was only grown as a decorative plant. The US quickly became a major creation of fruit, with orchards in Florida, Texas, Arizona, and California. In Spanish, the crop is known as toronja or pomelo.

A history of computer viruses

In the following report, “computer viruses” will be explained in aspect. A lengthy and educational description of the evolution and history on microcomputer viruses will be given; to give you a background of their origin for some understanding of how they came to be. The next segment in the statement is on how to battle computer viruses with the development of anti-virus applications.

The current status of microcomputer viruses will also be discuss, naming the most common types of viruses and the mass harmful type at this present point of time.
Details of the most new outbreaks of computer viruses, such as the “Melissa”, “I Love You” and the most recent “Anna Kournikova” viruses will be explained, and why they are so harmful.

Battery electric vehicle

The electric car, EV, or basically electric vehicle is battery electric vehicles (BEV) that make use of chemical energy stored in rechargeable battery packs. Electric vehicles use electric motors and motor controllers in its place of interior combustion engines (Ices). Vehicles using both electric motors and Ices are examples of hybrid vehicles, and are not deliberate pure BEVs because they operate in a charge-sustaining mode. Hybrid vehicles with batteries that can be thrilling externally to displace some or all of their ICE power and gasoline fuel are called plug-in hybrid electric vehicles (PHEV), and are pure BEVs during their charge-depleting mode. BEVs are normally automobiles, light trucks, neighborhood electric vehicles, motorcycles, motorized bicycles, electric scooters, golf carts, milk floats, forklifts and similar vehicles.
