oyster farming (There are two types of oyster farming: suspension culture, in which oysters are grown off bottom, in floating trays, is a labor-intensive form of cultivation that requires continuous tending and cleaning of both gear and shellfish, and bottom culture, which is similar to conventional crop farming on land; it involves selecting areas of the sea floor that provide a natural food supply, necessary currents, minimum exposure to predators, and proper temperature and then "seeding" the bottom with shellfish stock that are left to grow to market size. Then they are harvested with a bottom drag from a boat. Both suspension culture and bottom culture depend on natural food supplies for growing the shellfish being raised) |

osmosis (The passage of a solvent through a semipermeable membrane separating two solutions of different concentrations. A semipermeable membrane is one through which the molecules of a solvent can pass but the molecules of most solutes cannot. There is a thermodynamic tendency for solutions separated by such a membrane to become equal in concentration, the water (or other solvent) flowing from the weaker to the stronger solution. Osmosis will stop when the two solutions reach equal concentration, and can also be stopped by applying a pressure to the liquid on the stronger-solution side of the membrane. The pressure required to stop the flow from a pure solvent into a solution is a characteristic of the solution, and is called the osmotic pressure. Osmotic pressure depends only on the concentration of particles in the solution, not on their nature) |

paper industry (Industrial production of paper: pulp is produced by mechanically or chemically processing wood or other vegetative materials to extract usable cellulosic fibers as an aqueous slurry. The pulp slurry may be used directly in paper making or it may be shipped elsewhere for processing into paper products. The fundamental industrial operations are divided into two major categories: pulp mill and paper mill. The pulp mill operation includes wood preparation, pulping, deinking, pulp washing, screening and thickening, and bleaching. The paper mill operations include stock preparation, paper machine operation and finishing) |
