Possible definitions for caaming

camping
Recreational activity in which participants live outdoors, often in the wilderness, usually using tents, trailers, or motor homes, but sometimes only a sleeping bag, for shelter. Modern camping originated near the end of the 19th cent. in the U.S. as a rough, back-to-nature pastime for hardy lovers of nature. Canoes were the original vehicle; bicycle camping soon followed. Camping was a major part of the programs of the Boy Scouts and Girl Guides (see scouting). It gained greatly in popularity after World War II. As the number of campgrounds with greater amenities grew, it became the standard holiday for many ordinary families. Recent decades have seen its continued growth, to the point of placing a serious strain on the resources of state and federal outdoor-recreation areas. See also backpacking.


canning
Method of preserving food from spoilage by storing it in containers that are hermetically sealed and then sterilized by heat. The process was invented in 1809 by Nicolas Appert (c.1750-1841) of France, who used glass bottles. In the 19th cent. tin-coated iron cans with soldered tops, bottoms, and seams were used, but in the early 20th cent. these were replaced by tin-plated steel containers with interlocking seams and polymer seals. In the later 20th cent. seamless aluminum cans (punched out from a single sheet) capped with a steel or aluminum lid became common, particularly in the beverage industry. In modern canning, food is passed under hot water or steam, transferred to a sterile container, sealed inside, and subjected to heat sufficient to kill any remaining microorganisms. The process preserves most nutrients but often affects consistency and taste.


carding
In yarn production, a process of separating individual fibers and causing many of them to lie parallel, and also removing most of the remaining impurities. Cotton, wool, waste silk, and man-made staple are subjected to carding. Carding produces a thin sheet of uniform thickness that is then condensed to form a thick, continuous, untwisted strand called sliver. When very fine yarns are desired, carding is followed by combing, a process that removes short fibers, leaving a sliver composed entirely of long fibers, all laid parallel, and both smoother and more lustrous than uncombed types. Carded and combed sliver is then spun.


casting
Pouring of molten metal into a mold, where it solidifies into the shape of the mold. The process was well established in the Bronze Age, when it was used to form bronze pieces now found in museums. It is particularly valuable for the economical production of complex shapes, ranging from mass-produced parts for automobiles to one-of-a-kind production of statues, jewelry, or massive machinery. Most steel and iron castings (see cast iron) are poured into silica sand. For metals of lower melting point, such as aluminum or zinc, molds can be made of another metal or of sand. See ...
