: a factor of production; the term not only includes the number of
people available for or engaged in the production of goods or
services but also their physical and intellectual skills and effort. |

of gravity; also known as landslip. |

LASER
: Light Amplification by Stimulated Emission of Radiation
: an optical source that emits photons in a coherent beam; it was
proposed as a variation of the MASER principle in the late 1950s,
and the first laser was demonstrated in 1960. |

laser
: a source of coherent photons, i.e. light or other
electromagnetic radiation. As the MASER/LASER principle was applied
over a broad portion of the electromagnetic spectrum, the term
(acronym) 'LASER' has entered English language as a standard word
'laser', losing the capitalization in the process. The back-formed
verb 'lase' means 'to produce laser light' or 'to apply laser light
to'. Also, in analogy with optical lasers, a device which produces
any particles or electromagnetic radiation in a coherent state is
also called a 'laser', usually with indication of type of particle
as prefix (for example, 'atom laser'). |

legume
: any of a large group of plants of the pea family, characterized by
true pods enclosing seeds; because of their ability to store up
nitrates, legumes are often plowed under to fertilize the soil. The
term 'legume' is also used for the fruit of any plant of the pea
family, pod, often used as food, and a seed of such a plant,
contained in the pod. |

lenticel
: a lenticular cluster of cells in the periderm of
plants, functioning as a breathing pore on the young bark of
the stem to allow air to reach the underlying tissue, especially
during the winter; often the color contrasts with the bark. |

lime
(also called: burnt
lime, calcium oxide, caustic lime, calx, quicklime) : a
white or grayish-white, odorless, lumpy, very slightly water-soluble
solid, CaO, that when combined with water form calcium hydroxide
(slaked lime); obtained from calcium carbonate, limestone or oyster
shells; used chiefly in mortars, plasters, and cements, in bleaching
powder, and in the manufacture of steel, paper, glass, and various
chemicals of calcium. |

limestone
: a sedimentary rock consisting predominantly of calcium carbonate,
varieties of which are formed from the skeletons of marine
microorganisms and coral; used as a building stone and in the

log
: logarithmic function (logarithm)
: the logarithm (c) of a number (a)
is the exponent of that power (c) to which
another number (b), the base, must be raised
to give the number first named (a):
logba
=
c
a = bc
Any positive number
greater than 1 might serve as a base. Two traditionally and widely
used bases are b=10 (common or Briggsian logarithms) and
b=e=2.718... (natural or Napierian logarithms) while base b=2 is
recently catching up, thanks to electronic computing. |

loudness
(level of sound) : an apparent,
subjective acoustic scale which takes account of the variable human
sensitivity to different sound frequencies; there are two loudness
units of measurement: phon and sone. Phon is defined
as loudness of 1000 Hz sound at the sound pressure level of 20 µPa;
see [HANDBOOK].
Loudness level of a sound, expressed in phons, is numerically equal
to the sound pressure level, expressed in decibels, of the 1000 Hz
sound judged by listeners to be equivalent in loudness. Sone is
defined as loudness of 1000 Hz sound, 40 dB above a listener’s
threshold. Loudness level of a sound, expressed in sones, measures a
loudness level above threshold for a particular listener; for that
reason, the threshold (measured or assumed) should be always
specified. |

lucky
loser : in some knockout tournaments, one defeat does not
automatically result in elimination. Beaten players have the chance
to play again, if, for instance a player withdrew; these beaten
players are known as 'lucky losers'. |

luminous flux (also called: luminous
power): the time rate of flow of light; the time rate of flow
of electromagnetic radiant energy evaluated according to its
capacity to produce visual sensation. The visible spectrum is
usually considered to extend from 380 to 760 nm; therefore, luminous
flux is radiant flux in that region of the electromagnetic spectrum.
The SI unit of luminous flux is the lumen (lm), equal to
candela×steradian (cd sr), as luminous flux is the intensity of
light from a source multiplied by the solid angle. |
