Possible definitions for paced

acid
Any substance that in water solution tastes sour, changes the color of acid-base indicators (e.g., litmus), reacts with some metals (e.g., iron) to yield hydrogen gas, reacts with bases to form salts, and promotes certain chemical reactions (e.g., acid catalysis). Acids contain one or more hydrogen atoms that, in solution, dissociate as positively charged hydrogen ions. Inorganic, or mineral, acids include sulfuric acid, nitric acid, hydrochloric acid, and phosphoric acid. Organic acids include carboxylic acids, phenols, and sulfonic acids. Broader definitions of acids cover situations in which water is not present. See also acid-base theory.


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.


jackdaw
Crowlike black bird (Corvus monedula) with gray nape and pearly eyes. About 13 in. (33 cm) long, jackdaws breed in colonies in treeholes and on cliffs and tall buildings; their flocks fly in formation around the site. Their cry sounds like their name: "chak." The species ranges from the British Isles to central Asia. See also crow, grackle.


lace
Ornamental openwork fabric formed by the looping, interlacing, braiding, or twisting of threads, originally primarily of linen. Almost all high-quality artistic lace is made by one of two techniques: needle lace involves a difficult technique that originated in Italy; bobbin lace is a more widespread craft that originated in Flanders. The art of lace is a European achievement. Fully developed lace did not appear before the Renaissance. By 1600 lace had become a fabric of luxury and an important article of commerce. The Industrial Revolution in the 19th cent. led to the use of machines to produce less-expensive lace made of cotton, and lace gradually disappeared from both men's and women's fashions. By 1920 the industry was dying. Fine handmade lace is still made in ...
