The UCLA Loneliness Scale was the first loneliness scale to achieve widespread acceptance among scientists. It has since been revised several times, including in 1980 and 1996. Shorter versions have been released for use in cases where asking 20 questions would be too much, such as for short telephone interviews suitable to be undertaken for ...
Thermoelectric cooling uses the Peltier effect to create a heat flux at the junction of two different types of materials. A Peltier cooler, heater, or thermoelectric heat pump is a solid-state active heat pump which transfers heat from one side of the device to the other, with consumption of electrical energy, depending on the direction of the current.
Molecular scale electronics, also called single-molecule electronics, is a branch of nanotechnology that uses single molecules, or nanoscale collections of single molecules, as electronic components. Because single molecules constitute the smallest stable structures imaginable [ citation needed ] , this miniaturization is the ultimate goal for ...

Lowe, was an American Civil War aeronaut, scientist and inventor, mostly self-educated in the fields of chemistry, meteorology, and aeronautics, and the father of military aerial reconnaissance in the United States.

S scale (or S gauge) is a model railroad scale modeled at 1:64 scale, S scale track gauge (space between the rails) is 22.48 mm (0.885 in). [ 1 ] [ 2 ] [ 3 ] S gauge trains are manufactured in both DC and AC powered varieties.
Z scale is one of the smallest commercially available model railway scales (1:220), with a track gauge of 6.5 mm / 0.256 in.Introduced by Märklin in 1972, Z scale trains operate on 0–10 volts DC and offer the same operating characteristics as all other two-rail, direct-current, analog model railways.
