Sunday, April 19, 2015

   George Gascoigne was an English writer. Born Cardington, England, about 1525. Died Stamford, England, Oct. 7, 1577.
   Gascoigne was a pioneer in English Renaissance literature. A resourceful innovator, he was among the first English writers to use such literary forms as the prose comedy, verse tragedy, verse satire, novel, and critical essay. Gascoigne's The Supposes (1566) is the oldest existing English prose comedy, and his Jocasta (1566) is the second oldest English tragedy in blank verse.
Gascoigne also wrote The Adventures of Master F. J. (1573), which has been called the first English novel. His satiric poem The Steele Glas (1576) was the first original English poem, other than a verse drama, to be written in blank verse. Gascoigne also wrote fine lyric poetry.

Who was Rómulo Gallegos?

   Rómulo Gallegos was a Venezuelan novelist, educator, and statesman. Born Caracas, Venezuela, Aug. 2, 1884 - April 7, 1969.
   Gallegos' works include some of the finest novels in modern Spanish-American literature. His novels usually take place in the llanos, the vast tropical plains of Venezuela, and they depict a never-ending battle between civilization and barbarism. The most famous of his books are Doña Bárbara (1929) and Cantaclaro (1934).
   In his early life, Gallegos was a teacher. His first novel was El último Solar (1920), later revised and published as Reinaldo Solar (1930). Because he was opposed to the government of the Venezuelan dictator Juan Vicente Gomez, Gallegos went to Spain in voluntary exile in 1931 and stayed there until Gomez' death in 1935. For a time after his return to Venezuela he was minister of education. In 1947 he was elected president, but a military coup the next year removed him from office. During his years of political activity, Gallegos continued to write novels and to direct adaptations of his works for motion pictures.

What is Galvanizing?

Sunday, March 22, 2015

    Galvanizing is the coating of iron or steel with a thin layer of zinc to protect it from rusting, or oxidation. The iron or steel is protected by the zinc and by a thin layer of zinc oxide that forms on the zinc surface. It is further protected by an electrical reaction between zinc and iron that acts when the zinc coating is broken or scratched. Under these conditions the zinc is oxidized in place of the iron, and the exposed iron does not rust.
   In the United States most galvanized products, such as telegraph wire, garbage cans, and roofing and siding for buildings, are galvanized by the hot dipping method. In this process, iron or steel sheets are dipped into molten zinc. The zinc combines with the iron or steel to produce a protective layer of zinc-iron alloy overlaid by a layer of zinc. The entire coating is usually from 0.0002 inch to 0.004 inch thick.
   Electrogalvanizing, a less costly process, produces a thinner, less durable zinc coating. Here the iron or steel is placed in a solution of zinc or zinc salts. A strong electric current is passed through the solution to deposit a layer of 99.99 percent pure zinc on the surface of the steel or iron.
    Sherardizing is a process used to galvanize small items, such as nails or bolts. These are placed in a rotating drum containing fine zinc dust. The drum is heated to a temperature from 350 °C to 370 °C. (660 °F to 700 °F.), well below the melting point of zinc. As in hot dipping, a layer of zinc-iron alloy forms on the surface of the iron or steel.
   Large objects are often zinc-coated by being sprayed with molten zinc. This does not result in true galvanizing, since an alloy is not formed with the zinc.
   Galvanizing is named for Luigi Galvani, an 18th- century Italian physician who performed early experiments in electricity.

What is a depressant?

A depressant is a drug that reduces the activity of various body functions. Some depressants such as anesthetics, sedatives, antiepileptics, narcotics analgesics, and some muscle relaxants, slow nervous and muscular activity by acting on the central nervous system. Tranquilizers are depressants that affect only part of the nervous system. They induce relaxation without causing total depression.
