| lambert pine | <botany> The gigantic sugar pine of California and Oregon (Pinus Lambertiana). It has the leaves in fives, and cones a foot long. The timber is soft, and like that of the white pine of the Eastern States. Origin: So called from Lambert, an English botanist. Source: Websters Dictionary (01 Mar 1998) |

| beer-lambert law | The equation A=ECL, where A is the absorbance at a given wavelength of light, E is the molar extinction coefficient, C is the concentration of the molar solution, and L is the length of the light path. In words, the equation means that the concentration of a substance in moles is proportional to the absorption of a given wavelength of light by a solution of the substance. The equation is used in the study of spectroscopy. (09 Oct 1997) |

| pine | 1. <botany> Any tree of the coniferous genus Pinus. See Pinus. There are about twenty-eight species in the United States, of which the white pine (P. Strobus), the Georgia pine (P. Australis), the red pine (P. Resinosa), and the great West Coast sugar pine (P. Lambertiana) are among the most valuable. The Scotch pine or fir, also called Norway or Riga pine (Pinus sylvestris), is the only British species. The nut pine is any pine tree, or species of pine, which bears large edible seeds. See Pinon. The spruces, firs, larches, and true cedars, though formerly considered pines, are now commonly assigned to other genera. 2. The wood of the pine tree. 3. A pineapple. Ground pine. <botany> Any one of numerous species of weevils whose larvae bore in the wood of pine trees. Several species are known in both Europe and America, belonging to the genera Pissodes, Hylobius, etc. Pine wool, a fibre obtained from pine needles by steaming them. It is prepared on a large scale in some of the Southern United States, and has many uses in the economic arts. Synonym: pine-needle wool, and pine-wood wool. Origin: AS. Pin, L. Pinus.

| pine-needle oil | A volatile oil distilled with steam from the fresh leaf of Pinus mugo; has been used by inhalation and spray in catarrhal affections of the air passages, and locally in rheumatism; also used as a flavoring and in perfumery. (05 Mar 2000) |
| pine oil | The volatile oil from the wood of Pinus palustris and other species of Pinus; used as a deodorant and disinfectant. (05 Mar 2000) |
| pine tar | Obtained by the destructive distillation of the wood of Pinus palustris and other species of Pinus; used internally as an expectorant, and externally in the treatment of skin diseases. Synonym: liquid pitch. (05 Mar 2000) |
| white pine | The dried inner bark of Pinus strobus, used as an ingredient in cough syrups. (05 Mar 2000) |
| slash pine | <botany> A kind of pine tree (Pinus Cubensis) found in Southern Florida and the West Indies; so called because it grows in "slashes." Source: Websters Dictionary (01 Mar 1998) |
| oil of dwarf pine needles | Volatile oil from the fresh leaves of Pinus montana (family Pinaceae). Pleasant pine odour; used as a pharmaceutical aid (flavor and perfume). Has been used as an expectorant. (05 Mar 2000) |
| eaton-lambert syndrome | <radiology> Myasthenia, bronchial carcinoma, often small cell carcinoma (12 Dec 1998) |
| lambert | <unit> A unit of brightness; the brightness of a perfectly diffusing surface emitting or reflecting a total luminous flux of 1 lumen per sq cm of surface. Origin: J.H. Lambert, German physicist and mathematician, 1728-1777 (05 Mar 2000) |
| lambert-eaton myasthenic syndrome | <neurology> An acquired autoimmune disease characterised by weakness and fatigability of proximal muscles, particularly of the pelvic girdle and thighs, with relative sparing of extraocular and bulbar muscles. It is often associated with small cell carcinoma of the lung. The neuromuscular defect in this disease is believed to be due to a deficient release of acetylcholine. (08 Mar 2000) |
| Lambert-Eaton syndrome | <syndrome> A condition characterised by muscle weakness that is similar to the symptoms of myasthenia gravis. For this reason, it has been referred to as myasthenic syndrome. This disorder is caused by an insufficient release of neurotransmitter (acetylcholine) by the nerve cells. Unlike myasthenia gravis, as muscle contractions are continued, strength will increase. The cause of Lambert-Eaton syndrome is unknown, but is usually associated with small cell carcinoma of the lung or an autoimmune illness. (27 Sep 1997) |

| Lambert's law | Each layer of equal thickness absorbs an equal fraction of the light that traverses it; Cf.: Beer-Lambert law. The illumination of a surface on which the light falls normally from a point source is inversely proportional to the square of the distance from the source. (05 Mar 2000) |
