Abstract art

Abstract art is now usually understood to mean art that does not depict objects in the natural world, but instead uses color and form in a non-representational way. In the very early 20th century, the term was more often used to describe art, such as Cubist and Futurist art, which depicts real forms in a simplified or rather reduced way—keeping only an allusion of the original natural subject. Such paintings were often claimed to capture amazing of the depicted objects' immutable intrinsic qualities rather than its external appearance. The more precise terms, "non-figurative art," "non-objective art," and "non-representational art" avoid any possible ambiguity.

Ring

A finger ring is a band worn as kind of ornamental jeweler around a finger; it is the most ordinary current meaning of the word ring. Additional types of metal bands worn as ornaments are also called rings, such as arm rings and neck rings.

Rings are worn by both men and women and can be of any superiority. Rings can be made of metal, plastic, wood, bone, glass, gemstone and other equipment. They may be set with a "stone" of some sort, which is often a valuable or semi-precious gemstone such as ruby, sapphire or emerald, but can also be of almost any material.

There are a variety of methods for determining proper ring size. Quantities of the largest rings in the world are made for the winning team of the Super Bowl. The unofficial record for the largest championship ring ever obtainable to a professional sports team belongs to the 2003 World Series champions Florida Marlins, with a weight of over 110 grams and with over 240 stones.

Rings can be worn on any finger, still on toe fingers. In Western society, the traditional "ring finger" for the wearing of an engagement or wedding ring is the fourth finger of the left hand with the thumb counting as finger number one. The signet ring, a ring designate nobility, is normally worn on the little (fifth) finger of the right or left hand, depending on nationality.

Rainbow

Rainbows are optical and meteorological phenomena that reason of a spectrum of light to appear in the sky when the Sun shines onto droplets of moisture in the Earth's atmosphere. They take the form of a multicolored arc, with red on the external part of the arch and violet on the inner section of the arch. More rarely, a secondary rainbow is seen, which is a second, fainter arc, outside the primary arc, with colours in the differing order, that is, with violet on the outside and red on the inside.

A rainbow spans a permanent spectrum of colours. Traditionally, however, the chain of colours is quantized. The majority cited and remembered sequence, in English, is Newton's sevenfold red, orange, yellow, green, blue, indigo and violet. "Roy G. Biv" and "Richard of York Gave Battle In Vain" are admired mnemonics.

Though rainbows are bow-shaped in most cases, there are also phenomena of rainbow-colored flooring in the sky: in the shape of stripes, circles, or even flames.

Battery electric vehicle

The electric car, EV, or simply electric vehicle is battery electric vehicles (BEV) that utilize chemical energy stored in rechargeable battery packs. Electric vehicles use electric motors and motor controllers in its place of internal combustion engines (Ices). Vehicles using both electric motors and Ices are examples of hybrid vehicles, and are not measured pure BEVs because they operate in a charge-sustaining mode. Hybrid vehicles with batteries that can be exciting 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 frequently automobiles, light trucks, neighborhood electric vehicles, motorcycles, motorized bicycles, electric scooters, golf carts, milk floats, forklifts and similar vehicles.

BEVs were among the earliest automobiles, and are more energy-efficient than interior combustion, fuel cell, and most other types of vehicles. BEVs create no tire fumes, and minimal pollution if charged from most forms of renewable energy. Many are capable of acceleration more than that of conventional vehicles, are quiet, and do not produce noxious fumes. It has been optional that, because BEVs reduce dependence on petroleum, they enhance national safety, and mitigate global warming by alleviating the greenhouse effect.

Tomato

The tomato (Solanum lycopersicum) is a plant in the Solanaceae or nightshade family, as are its close cousin’s tobacco, chili peppers, potato, and eggplant. The tomato is subject to Central, South, and southern North America from Mexico to Peru. It is a perennial, often grown outdoors in temperate climates as an annual, typically attainment to 1–3 m (3 to 10 ft) in height, with a weak, woody stem that often vines over other plants.

The leaves are 10–25 cm long, pinnate, with 5–9 leaflets, each leaflet up to 8 cm long, with a jagged margin; both the stem and leaves are thickly glandular-hairy. The flowers are 1–2 cm across, yellow, with five sharp lobes on the corolla; they are borne in a cyme of 3–12 together. The word tomato derives from an expression in the Nahuatl language, tomatl. The exact name, lycopersicum, means "wolf-peach" compare the related species S. lycocarpum, whose scientific name means "wolf-fruit", common name "wolf-apple".

Fertilization

Fertilization or fertilization also known as conception, fecundation and syngamy, is fusion of gametes to form a new organism of the same variety. In animals, the process involves a sperm fuse with an ovum, which finally leads to the development of an embryo. Depending on the animal species, the process can occur within the body of the female in interior fertilisation, or outside in the case of external fertilisation.

The entire process of development of new persons is called procreation, the act of species reproduction.

Donkey jacket

A Donkey jacket is a tiny buttoned coat, normally made of unlined black or dark blue woolen stuff; originally worn as a work jacket in the United Kingdom.
When used as a work jacket, it occasionally bears the name of the company which supplies the jacket, or the name of the company for which the wearer works. The jacket usually has two large hip pockets, and at times an inside poacher's pocket.
The donkey jacket is regarded as characteristic of the British manual worker.
