The Prentice position. The Prentice position is an orientation of a prism, used in optics, optometry and ophthalmology. [1] In this position, named after the optician Charles F. Prentice, the prism is oriented such that light enters it at an angle of 90° to the first surface, so that the beam does not refract at that surface.
An Uppendahl prism is an erecting prism, i.e. a special reflection prism that is used to invert an image (rotation by 180°). The erecting system consists of three partial prisms made of optical glass with a high refractive index cemented together to form a symmetric assembly and is used in microscopy as well as in binoculars technology.

The prism is also less bulky than the double Porro design. The prism is sometimes simply called a "roof prism", although this is ambiguous, because other roof prisms exist, such as the Amici and Schmidt–Pechan designs. A variant of the Abbe–Koenig prism replaces the "roof" section of the prism with a single mirror-coated reflecting surface.
The Israel Prison Service (Hebrew: שירות בתי הסוהר, Sherut Batei HaSohar, Arabic: إدارة السجون الإسرائيلية, Idārat al-Sujūn al-Isrā’īlīyyah), [1] known in Israel by its acronym Shabas (שב״ס ) or IPS in English, is the state agency responsible for overseeing prisons in Israel.
A dental abscess is a localized collection of pus associated with a tooth. The most common type of dental abscess is a periapical abscess , and the second most common is a periodontal abscess . In a periapical abscess, usually the origin is a bacterial infection that has accumulated in the soft, often dead, pulp of the tooth.
Prism adaptation is a sensory-motor adaptation that occurs after the visual field has been artificially shifted laterally or vertically. It was first introduced by Hermann von Helmholtz in late 19th-century Germany as supportive evidence for his perceptual learning theory (Helmholtz, 1909/1962). [1]
