Possible definitions for jacet

acetate
C2H3O2- ion, a salt, ester, or acylal derived from acetic acid. Acetates are important in the biochemical synthesis of fats from carbohydrates in plants and animals. Industrially, metal acetates are used in printing, vinyl acetate in plastic production, cellulose acetate in photographic films and textiles (one of the first synthetic fibers, often called simply acetate), and volatile organic esters as solvents.


acetone
Simplest and most important ketone (CH3COCH3). It is a colorless, flammable liquid, boiling at 133\u00b0 F (56.2\u00b0 C). Many fats, resins, and organic materials dissolve easily in it, so it is used to make artificial fibers, explosives, resins, paints, inks, cosmetics (incl. nail-polish remover), coatings, and adhesives. Acetone is used as a chemical intermediate in pharmaceuticals and many other compounds.


dace
Any of various small, slim, active freshwater fishes of the carp family (Cyprinidae). In England and Europe, the dace (Leuciscus leuciscus), a relative of the European chub, inhabits streams and rivers. It is a small-headed, silvery fish that grows to 10-12 in. (25-30 cm) long and weighs 1-1.5 lbs (0.5-0.7 kg). It lives in schools and eats plant and animal material. It is a good bait and sport fish but is not highly valued as food. In N. America, the name is applied to various small cyprinids found in creeks and bogs, mostly in the central and S U.S.


face
Front part of the head, extending from the forehead to the chin and housing the eyes, nose, mouth, and jaws. The receding of the jaw and the increasing size of the brain in human evolution has made the face essentially vertical, with two distinctively human features: a prominent, projecting nose and a clearly defined chin. The face and braincase follow different patterns of growth. While the face grows more slowly, it ends up much larger compared to the braincase in adults than at birth. The facial muscles move the features to express emotion.


jacama
Leguminous vine (Pachyrhizus erosus, or P. tuberosus), also called yam bean. A native of Mexico and Central and S. America, it is grown for its edible root. The irregularly globular, brown-skinned tubers are white-fleshed, crisp, and juicy. There are two varieties, those with clear juice and those with milky juice. Both have a mild flavor and are eaten raw or cooked. Sometimes very young seedpods of the plant are eaten, but the mature seeds are highly toxic.


jack
In practical mechanics, portable hand-operated device for raising heavy weights through short distances, exerting great pressures, or holding assembled work firmly in position. The ratio of the load to the amount of force applied to the handle can be made quite high by using a gear or screw to regulate the upward extension. A ratchet allows a heavy weight to be raised in short successive stages. Though limited by the requirements of portability ...
