A forest is an area with a high bulk of trees. There are several definitions of a forest, based on a variety of criteria. These plant communities face large areas of the globe and function as animal habitats, and soil conservers, constituting one of the most important aspects of the Earth's biosphere. While frequently thought of as carbon dioxide sinks, grown-up forests are approximately carbon neutral with only troubled and young forests acting as carbon sinks. However mature forests do play a main role in the global carbon cycle as stable carbon pools, and authorization of forests leads to an increase of impressive carbon dioxide levels.

Forests sometimes have many tree species within a small area or comparatively few species over large areas. Forests are frequently home to many animal and plant species, and biomass per unit area is high compared to other plants communities. Much of this biomass occurs below-ground in the origin systems and as partly decomposed plant accumulation. The woody element of a forest contains lignin, which is comparatively slow to decompose compared with other organic materials such as cellulose or carbohydrate.

A village is a clustered person resolution or community, better than a hamlet, but smaller than a town or city. Although usually situated in rural areas, the word urban village may be applied to assured urban neighborhoods. Villages normally are stable with fixed dwellings, but temporary villages can occur. Further, the dwellings of a village are quite close to one another, as against being spread broadly over the landscape.

During the human past, villages have been the normal form of society for agricultural societies, and even for some non-agricultural societies. Towns and cities were few, and were home to only a little proportion of the population. The Industrial Revolution caused a lot of villages to develop into towns and cities; this development of urbanisation has continued and hastened since, even if not always in connection with industrialisation. Villages have thus been eclipsed in value, as units of human culture and settlement.

Biography is a type of literature and further forms of media such as film, based on the written accounts of individual lives. While a biography may focus on a subject of fiction or non-fiction, the term is frequently in reference to non-fiction. Pat Shipman however, says "I think a good biographer has to write fiction some of the time to make apparent a significant event in someone's life." This is sometimes debated. As opposed to a profile or curriculum vitae, a biography develops a complex analysis of personality, highlighting different aspects of it and including intimate details of experiences. A biography is more than a list of distant facts like birth, education, work, relationships and death. It also delves into the emotions of experiencing such events.

Ancient Greeks developed the biographical tradition which we have inherited, although until the 5th century AD, when the word 'biographia' first appears, in Damascius' Life of Isodorus, biographical pieces were called simply "lives" . It is quite likely that the Greeks were drawing on a pre-existing eastern tradition; certainly Herodotus' Histories contains more exhaustive biographical information on Persian kings and subjects than on anyone else, implying he had a Persian source for it.

Entertainment is an occasion, piece, or movement designed to give enjoyment or leisure to an audience. The audience may join in the entertainment passively as in actively as in computer games. The playing of sports and reading of journalism are usually included in entertainment, but these are regularly called activity more specifically, because they involve some energetic participation past mere leisure.

While people have laughing themselves since the beginning of time, the entertainment industry first became a leading force in culture in the 20th century with the development of latest electronic technologies of recording and spreading. Western peoples, tired of serious purposes and gathering massacre, turned to popular culture following the two world wars. The financial basis of this new culture was advertising of free or inexpensive entertainment program. In their peak, television networks were great selling machines which, besides entertaining people, prohibited both commercial and political markets by providing direct access to the group of customers. This "territory" is now in danger by the explosion and segmentation of media and especially by the growing importance of communication by computer which allows the consumer to look for out the informational message as an alternative of having it broadcast to him or her. A new system of world history sees Americans in changeover between a fourth, entertainment-based "society" and a future fifth evolution based on computer communication.

In 1969, a pair of Argentine brothers that lived in Los Angeles, California, discovered the Hot Wheels brand. They figured out that, using Hot Wheels' building techniques, they would be able to make economic progress by making and selling their own Die-Cast products. In 1970, the brothers flew back to Argentina with a few Hot Wheels models. As a matter of a fact, many call the Muki cars the "Hot Wheels of Argentina".
Shortly after setting up a manufacturing center north of Buenos Aires, the two brothers put their die-cast cars on the market. The cars enjoyed much success, despite lagging in popularity among children, behind one of their fiercest competitors, the Buby toy cars. The Muki brand had catalogs published during that decade.
By 1983, the two brothers that were the original owners of the "Muki" brand had earned enough money to buy mansions in Brazil, and they moved there, showing little interest in keeping the brand running. That year, the Indugay toy making company bought over the rights to produce Muki models. Muki models kept being produced under their original name, but with a small "Indugay" logo to the bottom of the model packages.

Infrared (IR) emission is electromagnetic emission of a wavelength longer than that of noticeable light, but shorter than that of radio waves. The name means "below red", red being the color of detectable light of longest wavelength. Infrared radiation spans three instructions of magnitude and has wavelengths between about 750 nm and 1 mm.

These divisions are suitable by the different human response to this radiation: near infrared is the area closest in wavelength to the radiation detectable by the human eye, mid and far infrared are gradually further from the visible regime. Other definitions follow different physical mechanisms and the newest follow technical reasons .Unfortunately the international standards for these specifications are not currently obtainable.

The boundary between visible and infrared light is not precisely defined. The human eye is markedly less responsive to light above 700 nm wavelength, so longer frequencies make irrelevant contributions to scenes illuminated by common light sources. But particularly strong light (e.g., from lasers, or from bright daylight with the visible light removed by colored gels can be detected up to approximately 780 nm, and will be apparent as red light. The onset of infrared is defined at different values typically between 700 nm and 780 nm.
