Brown Jurassic

The Brown Jurassic or Brown Jura (German: Brauner Jura or Braunjura) in earth history refers to the middle of the three lithostratigraphic units of the South German Jurassic, the latter being understood not as a geographical, but a geological term in the sense of a lithostratigraphic super group. Formerly and even occasionally today in the popular scientific literature, this term is equated to the chronostratigraphic series of the Middle Jurassic. This is however not quite correct, because the Brown Jura does not exactly coincide with the chronostratigraphic boundaries of the Middle Jurassic. In addition, the term Dogger, which was formerly frequently used (and sometimes is today) as a synonym should no longer be used in connexion with the South German Jurassic. Instead the term "Dogger" should be reserved for the roughly equivalent lithostratigraphic unit in the North German Jurassic. The Brown Jurassic was deposited about 175-161 million years ago. The Brown Jurassic follows the lithostratigraphic unit of the Black Jurassic and is superimposed on the lithostratigraphic group of the White Jurassic.

Brown

Brown is the color of dark wood or rich soil. Brown is a composite color; in printing or painting, brown is made by combining red, black and yellow, or red, yellow and blue. In the RGB color model used to make colors on television screens and computer monitors, brown is made by combining red and green, in specific proportions. The brown color is seen widely in nature, in wood, soil, and human hair color, eye color and skin pigmentation. In Europe and the United States, brown is the color most often associated with plainness, humility, the rustic, and poverty. Brown is also, according to public opinion surveys in Europe and the United States, the least favorite color of the public.

Brown sugar

Brown sugar is a sucrose sugar product with a distinctive brown color due to the presence of molasses. It is either an unrefined or partially refined soft sugar consisting of sugar crystals with some residual molasses content (natural brown sugar), or it is produced by the addition of molasses to refined white sugar (commercial brown sugar).

The Codex Alimentarius requires brown sugar to contain at least 88% of sucrose plus invert sugar. Commercial brown sugar contains from 4.5% molasses (light brown sugar) to 6.5% molasses (dark brown sugar) based on total volume. Based on total weight, regular commercial brown sugar contains up to 10% molasses. The product is naturally moist from the hygroscopic nature of the molasses and is often labelled as "soft." The product may undergo processing to give a product that flows better for industrial handling. The addition of dyes and/or other chemicals may be permitted in some areas or for industrial products.

Particle size is variable but generally less than granulated white sugar. Products for industrial use (e.g., the industrial production of cakes) may be based on caster sugar which has crystals of approximately 0.35 mm.

Brown (1814 cricketer)

Brown (first name and dates unknown) was an English first-class cricketer associated with Marylebone Cricket Club (MCC) who was active in the 1810s. He is recorded in one match in 1814, totalling 11 runs with a highest score of 7 not out.
