Hygrometers are instruments used for measuring humidity. The simplest form of a hygrometer consists of two thermometers, one of which has its bulb constantly kept wet. Evaporation from the bulb lowers the temperature so that this thermometer shows a lower temperature. Humidity is computed from the ambient temperature as shown by the "dry bulb thermometer" and the difference in temperature shown by the "wet bulb" and dry bulb thermometers. ...

| SLT |
Solid Logic Technology (SLT) was IBMs method for packaging electronic circuitry introduced in 1964 with the IBM System/360 series and related machines. Because monolithic integrated circuits were not considered to be mature enough at the time. IBM chose to design custom hybrid circuits using discrete, flip chip-mounted, glass-encapsulated transistors and diodes, with silk screened resistors on a ceramic substrate. The circuits were either encapsulated in plastic or covered with a metal lid. ...

Slugs are gastropods without shells or with very small shells, in contrast with snails from which they evolved, which have a prominent shell. Although they undergo torsion (twisting) during development, their bodies are streamlined and worm-like, and so show little external evidence of it. This same basic design developed independently in several different groups, the largest being the sea slugs or nudibranchs. ...

A railroad slug is an accessory to a locomotive. A slugs has trucks with traction motors but is unable to move about under its own power as it does not contain a prime mover. Instead, it is connected to a locomotive, called the mother, which provides current to operate the traction motors. Sometimes a locomotive will be connected to each end of the slug and both will provide power to it. ...

Slide is a common term that refers to a shoe that is backless and open-toed, essentially an open-toed mule. Generally, all slides are a type of sandal. Thongs and flip flops are normally classified separately. Slides can be high-heeled, flat-heeled or somewhere in between, and may cover nearly the entire foot from ankle to toe, or may have only one or two narrow straps. ...
