Possible definitions for rinde

linden
Any of about 30 species of trees that make up the genus Tilia (family Tiliaceae), native to the Northern Hemisphere. A few are outstanding deciduous ornamental and shade trees, with heart-shaped, coarsely toothed leaves, fragrant cream-colored flowers, and small globular fruit. The Amer. linden (T. americana), also called basswood or whitewood, grows as high as 130 ft (40 m). Its wood is used for beehives, crating, furniture, and packing material; like other linden species, it is also a popular bee tree, yielding a distinctive, pale, fragrant honey.


diode
Electronic device that has two electrodes (anode and cathode) and that allows current to flow in only one direction, resisting current flow in the other. An applied voltage can cause electrons to flow only in one direction, from the cathode to the anode, and then back to the cathode through an external circuit. Diodes are used especially as rectifiers--which change alternating current into direct current--and to vary the amplitude of a signal in proportion to the voltage in a circuit, as in a radio or television receiver. The most familiar diodes are vacuum tubes and semiconductor diodes. Semiconductor diodes, the simplest of semiconductor devices, consist of two electrodes and a sandwich of two dissimilar semiconducting substances (a p-n junction). Such diodes form the basis for more complex semiconductor devices (incl. transistors) used in computers and other electronic equipment. Semiconductor diodes include light-emitting diodes and laser diodes; the latter emit laser light, useful for telecommunications via fiber optics and for reading compact discs.


Donders
Dutch ophthalmologist. His study of "muscae volitantes" (spots before the eyes) resulted in Donders' law, stating that the rotation of the eye around the line of sight is involuntary. His research improved diagnosis, operative treatment, and use of eyeglasses for vision problems. He found that in farsightedness the eyeball is shortened, resulting in light rays being focused behind the retina (1858). His finding that astigmatism is caused by uneven cornea and lens surfaces (1862) created the field of scientific clinical refraction. His On the Anomalies of Accommodation and Refraction (1864) was the first authoritative work in the field.


Dundee
City (pop., 1995 est.: 168,000), headquarters of Tayside administrative region, Scotland. An important seaport, it is situated on the Firth of Tay, a North Sea inlet. Earliest mention of the town dates from the late 12th cent., and over the next several centuries it saw repeated sackings and much bloodshed by the English. Among surviving buildings, the City Churches, a collection of three parish churches housed under one roof, are a focal point in the modern city center. Dundee was a world center for jute manufacturing in the 19th cent. Textiles are still produced, but since World War II light-engineering has become ...
