n: See mist.

a suspension of fine liquid droplets or solid particles in a gas.

n: the grouping of individual particles.

n: The process that the size
in the disperse phase turns from thin to bastard, from small to big through the absorption of particles in the multiphase disperse system.

forming larger droplets, bubbles, or particles from smaller droplets, bubbles, or particles.

n: a large, sloping sedimentary deposit at the mouth of a canyon, laid down by intermittently flowing water, especially in arid climates, and composed of gravel and sand. The deposit tends to be coarse and unworked, with angular, poorly sorted grains in thin, overlapping sheets. A line of fans may eventually coalesce into an apron that grows broader and higher as the slopes above are eroded away.

land counterpart of a river delta. Characteristic of sediments that have been transported by a fast moving stream then dropped out of the flow as the stream velocity drops as it spreads out. Typical of zones of heavy water runoff such as found at the base

n: (Ac) a white or gray midlevel cloud that appears as closely arranged rolls. This type of cloud is composed of either ice crystals or water droplets.

n: a bluish or gravish layer of uniform mid-level clouds that cover large portions of the sky. This type of cloud is composed of either ice crystals or water droplets.

n: US organisation that sets standards and specifications for ships and ship equipment manufactured in the United States. The organisation also makes inspections during offshore rig construction and conducts periodic surveys to ensure that requirements for classification are maintained. Its official publications are Records of the American Bureau of Shipping and ABS Activity Report. Address: 2 World Trade Centre;106th floor;New York, NY 10048;(212) 839- 5000.

n: organisation that sets guidelines for the testing and use of equipment and materials. Its publications are ASTM Standardisation News, Book of Standards, Cement and Concrete Aggregates Journal, Composites Technology & Research, Geo technical Testing Journal, Journal of Forensic Science, and Journal of Testing and Evaluation. Address: 100 Barr Harbor;West Conshohocken, PA 19428;(610) 832-9500.

n: one type of misalignment in a chain-and-sprocket drive. The shafts are not parallel to each other (they form an angle) in either the horizontal or the vertical plane. This pulls the link plates on one side tighter than those on the other side;thus, one side of the chain and sprockets wears faster than the other. Link plates on only one side of the chain break because of fatigue.

a negatively charged surfactant. Normally water wets sands.

ring compound materials in the oil composed of carbon, hydrogen, sulfur, nickel and other trace materials. Asphaltenes are mostly very small platelets (35 A) suspended by micelles of maltenes and resins and carried through the oil. They precipitate by agg
