In toxicology, the margin of exposure (or MOE) of a substance is the ratio of its no-observed-adverse-effect level to its theoretical, predicted, or estimated dose or concentration of human intake. [1] It is used in risk assessment to determine the dangerousness of substances that are both genotoxic and carcinogenic. [2]
Managing Collateral Movements: to record details of the collateralised relationship in the collateral management system, to monitor customer exposure and collateral received or posted on the agreed mark-to-market, to call for margin as required, to transfer collateral to its counterparty once a valid call has been made, to check collateral to ...
Hollywood accounting (also known as Hollywood bookkeeping) is the opaque or "creative" set of accounting methods used by the film, video, television and music industry to budget and record profits for creative projects.
The framework replaced both non-internal model approaches: the Current Exposure Method (CEM) and the Standardised Method (SM). It is intended to be a "risk-sensitive methodology", i.e. conscious of asset class and hedging , that differentiates between margined and non-margined trades and recognizes netting benefits ; considerations ...
The permissible exposure limit (PEL or OSHA PEL) is a legal limit in the United States for exposure of an employee to a chemical substance or physical agent such as high level noise. Permissible exposure limits were established by the Occupational Safety and Health Administration (OSHA). Most of OSHA's PELs were issued shortly after adoption of ...
Within a normal exposure range for film stock, for example, the reciprocity law states that the film response will be determined by the total exposure, defined as intensity × time. Therefore, the same response (for example, the optical density of the developed film) can result from reducing duration and increasing light intensity, and vice versa.
In radiography, exposure latitude and dynamic range are equivalent. [2] [3] It is the range of exposures that can be recorded as useful densities on a radiographic film for interpretation. [4] In film-screen radiography, exposure latitude range from 10:1 to 100:1. In digital chest radiography, exposure latitude can more than 100:1.
In many instances, this was done: the 1973 and 1986 ANSI exposure guides, ANSI PH2.7-1973 and ANSI PH2.7-1986, eliminated exposure calculator dials in favor of tabulated APEX values. However, the logarithmic markings for aperture and shutter speed required to set the computed exposure were never incorporated in consumer cameras.
