Corpuscularianism is similar to the theory of atomism, except that where atoms were supposed to be indivisible, corpuscles could in principle be divided.In this manner, for example, it was theorized that mercury could penetrate into metals and modify their inner structure, a step on the way towards the production of gold by transmutation.
A back-released click, sometimes more precisely a velar-released click or uvular-released click, is a click consonant found in paralinguistic use in languages across Africa, such as Wolof. [ 1 ] [ 2 ] The tongue is in a similar position to other click articulations, such as an alveolar click , and like other clicks, the airstream mechanism is ...
This theory came to dominate the conceptions of light in the eighteenth century, displacing the previously prominent vibration theories, where light was viewed as "pressure" of the medium between the source and the receiver, first championed by René Descartes, and later in a more refined form by Christiaan Huygens.

Medical ethics is an applied branch of ethics which analyzes the practice of clinical medicine and related scientific research. [1] Medical ethics is based on a set of values that professionals can refer to in the case of any confusion or conflict. These values include the respect for autonomy, non-maleficence, beneficence, and justice. [2]
The United States Department of Veterans Affairs was an early adopter of a standardized approach to incorporating visible light images into the electronic medical record [7]. Increasingly, visible light imaging is being deployed beyond individual departments, as part of a trend referred to as Enterprise Imaging [ 8 ] .
Emission theory or extramission theory (variants: extromission) or extromissionism is the proposal that visual perception is accomplished by eye beams emitted by the eyes. This theory has been replaced by intromission theory (or intromissionism ), which is that visual perception comes from something representative of the object (later ...
Terms like pre-velar (intermediate between palatal and velar), post-velar (between velar and uvular), and upper vs. lower pharyngeal may be used to specify more precisely where an articulation takes place. However, although a language may contrast pre-velar and post-velar sounds, it does not also contrast them with palatal and uvular sounds (of ...
In both regions the languages retain a labialized velar series (e.g. [kʷ], [kʼʷ], [xʷ], [w] in the Pacific Northwest) as well as uvular consonants. [8] In the languages of those families that retain plain velars, both the plain and labialized velars are pre-velar, perhaps to make them more distinct from the uvulars which may be post-velar ...
