Char

Char is the solid material that remains after light gases (e.g. coal gas) and tar have been driven out or released from a carbonaceous material during the initial stage of combustion, which is known as carbonization, charring, devolatilization or pyrolysis.

Further stages of efficient combustion (with or without char deposits) are known as gasification reactions, ending quickly when the reversible gas phase of the water gas shift reaction is reached.

Chara (magazine)

Chara (Japanese: Charaの本棚) is a Japanese bi-monthly Yaoi/Shōjo manga magazine published by Tokuma Shoten. First released in 1994, the magazine has since been adapted into two different spinoffs.

History

Chara was first published in 1994 as an offshoot of Animage. In the 22nd issue of Chara, it was announced that a split-off magazine entitled "Chara Selection" would co-circulate. Later on, another split-off entitled Char@ was made. The website for Chara was designed by C&S Design in 2014.

Salvelinus

Salvelinus is a genus of salmonid fish often called char or charr; some species are called "trout". Salvelinus is a member of the Salmoninae subfamily of the Salmonidae family. The genus has a northern circumpolar distribution, and most of its members are typically cold-water fish that primarily inhabit fresh waters. Many species also migrate to the sea, however.

Most char may be identified by light-cream, pink, or red spots over a darker body. Scales tend to be small, with 115-200 along the lateral line. The pectoral, pelvic, anal, and the lower aspect of caudal fins are trimmed in snow white or cream leading edges.

Many members of this genus are popular sport fish, and a few, such as the lake trout (S. namaycush), are the object of commercial fisheries and aquaculture. Occasionally, such fish escape and become invasive species.

Deepwater char are small species of char living below 80 m in the deep areas of certain lakes. They are highly sensitive to changes in the quality of the water and some species, such as Salvelinus neocomensis and Salvelinus profundus, were driven recently to extinction.

Surface

In mathematics, specifically, in topology, a surface is a two-dimensional, topological manifold. The most familiar examples are those that arise as the boundaries of solid objects in ordinary three-dimensional Euclidean space R³, such as a sphere. On the other hand, there are surfaces, such as the Klein bottle, that cannot be embedded in three-dimensional Euclidean space without introducing singularities or self-intersections.

To say that a surface is "two-dimensional" means that, about each point, there is a coordinate patch on which a two-dimensional coordinate system is defined. For example, the surface of the Earth resembles (ideally) a two-dimensional sphere, and latitude and longitude provide two-dimensional coordinates on it (except at the poles and along the 180th meridian).

The concept of surface finds application in physics, engineering, computer graphics, and many other disciplines, primarily in representing the surfaces of physical objects. For example, in analyzing the aerodynamic properties of an airplane, the central consideration is the flow of air along its surface.

Surface (magazine)

Surface is an American design, Architecture, and fashion magazine. The magazine is published 10 times a year. Surface magazine covers in depth design profiles of prominent architects, designers, artists and photographers. Marc Lotenburg is the CEO and Spencer Bailey is the Editor in Chief.

History

Surface was founded in 1993 by Richard Klein and Riley Johndonnell. The magazine was based in San Francisco until 2005, when the main offices moved to New York City.

In 1994, Surface Magazine was one of 10 magazines dubbed as “upstart magazines to watch” by Vanity Fair.

In 1997, Surface introduced its first Avant Guardian issue, which focused on the Avant Guardian Awards, a photography competition that presents an opportunity for up and coming photographers to gain recognition and jumpstart their careers in the fashion editorial world. Winners have gone on to work for world renowned fashion houses and magazines like Giorgio Armani, Hermès, Banana Republic, Nike, IBM and Levi's—as well as magazines like Vogue, Elle, Harper’s Bazaar, Mademoiselle, and The New York Times Magazine. 10 finalists are chosen by heads of fashion and design, and have their work featured in a blowout fashion spread and showcased at a special launch event.
