polysomnography |
Polysomnography is the multi-parametric test used in the study of sleep. The name is derived from Greek roots: 'Poly' (many), 'somno' (sleep), and 'graphy' (writing). Originally developed by Nathaniel Kleitman and graduate students at the University of Chicago in the 1950s, it has since been codified by the adoption in 1968 of A Manual of Standardized Terminology, Techniques, and Scoring Systems for Sleep Stages of Human Subjects, edited by Allan Rechtschaffen and Anthony Kales. ...

polysiloxane |
Silicones, or polysiloxanes, are inorganic polymers consisting of a silicon-oxygen backbone (...-Si-O-Si-O-Si-O-...) with side groups attached to the silicon atoms. Certain organic side groups can be used to link two or more of these -Si-O- backbones together. By varying the -Si-O- chain lengths, side groups, and crosslinking, silicones can be synthesized into a wide variety of materials. They can vary in consistency from liquid to gel to rubber to hard plastic. ...
