Satellite Power System (SPS)

Concept for providing large amounts of electricity for use on the Earth from one or more satellites in geosynchronous Earth orbit. A very large array of solar cells on each satellite would provide electricity, which would be converted to microwave energy and beamed to a receiving antenna on the ground. There, it would be reconverted into electricity and distributed the same as any other centrally generated power, through a grid.

Mineral based industry

The State being a rich reserve of mineral resources, it has an immense potential for the growth of mining and mineral based industries. The important minerals available in the State are coal, iron ore, limestone, copper ore, bauxite, pyrite, china clay, kyanite, fine clay, dolomite, graphite, bentonite, soap stone, quartz sand and silica sand. Given this, there are numerable opportunities for the investors, in the following areas:-

Iron ore (export potential); Steel production; Sponge iron plant; Cement plant; Graphite electrodes and graphite powder; Granite (export Potential); Chemicals and fertilizers; Bleaching powder, calcium carbide and lime related chemicals; Ground mica, mica bricks and electrical appliances; etc.

The State Government has been making all efforts to attract investment into this industry. These include, simplification of the procedures with respect to grant of mining leases; provision of certain relief to make mining activities easier; suitable steps for adoption of state of art technology in mining; etc.

Sociology of education

The sociology of education is the learning of how social institutions and services have an effect on educational processes and outcomes, and vice versa. By many, education is understood to be a means of overcome the handicaps, achieve greater equality and acquire wealth and status for all (Sargent 1994). Learners may be provoked by aspirations for progress and betterment. Education is perceived as a place where children can expand according to their unique needs and potentialities. The principle of education can be to build up every individual to their full potential. The understanding of the goals and means of educational socialization processes differs according to the sociological model used.

Subsoil

It is the layer of soil under the topsoil on the surface of the ground. The subsoil may include substances such as clay and has only been partly broken down by air, sunlight, water etc., to create true soil. Below the subsoil is the substratum, which can be residual bedrock, sediments, or Aeolian deposits, largely unchanged by soil-forming factors active in the subsoil? It contains partially weathered particles.

Cargo

Cargo or freight is a word used to signify goods or produce being transported normally for commercial gain, usually on a plane, ship, train, truck or van. In modern times, containers are used in most intermodal long-haul cargo transport.

Cargo represents a concern to U.S. national security and is it was reported out of Washington, DC that in 2003 over 6 million cargo containers enter the United States each year. After the terrorist attacks of September 11th, the security of this extent of cargo has become highlighted. The latest US Government response to this threat is the CSI: Container Security Initiative. CSI is a program planned to help increase security for containerized cargo shipped to the United States from around the world.

Process of oil painting

The process of oil painting varies from artist to artist, but frequently includes certain steps. First, the artist prepares the surface. Although surfaces like linoleum panel, paper, slate, pressed wood, and cardboard have been used, the most well-liked surface since the 16th century has been canvas, even though many artists used panel through the 17th century and beyond. Before that it was panel, which is more luxurious, heavier, less easy to transport, and prone to warp or split in poor conditions. For fine detail, however, the absolute solidity of a wooden panel gives an advantage.

The artist might sketch an outline of their subject prior to apply pigment to the surface. "Pigment" may be any number of natural substances with color, such as sulphur for yellow or cobalt for blue. The pigment is varied with oil, usually linseed oil but other oils may be used as well. The various oils dry in a different way creating assorted effects.

Traditionally, an artist assorted his or her own paints for each project. Handling and mixing the raw pigments and mediums was prohibitive to transportation. This changed in the late 1800s, when oil paint in tubes became extensively available. Artists could mix colors rapidly and easily without having to grind their own pigments. Also, the portability of tube paints allowed for plein air, or outdoor painting.
