Decirad
The rad is a unit of absorbed radiation dose, defined as 1 rad = 0.01 gray (unit), Gy = 0.01 J/kg. It was originally defined in Centimetre gram second system of units, CGS units in 1953 as the dose causing 100 ergs of energy to be absorbed by one gram of matter. The material absorbing the radiation can be human tissue, air, water, or any other substance. It has been replaced by the gray (unit), gray (symbol Gy) in SI derived units, but is still used in the United States, although this is "strongly discouraged" in Chapter 5.2 of the ''Guide to the SI'', which was written and published by the U.S. National Institute of Standards and Technology. However, the numerically equivalent SI unit submultiple, the centigray (symbol cGy), is widely used to report absorbed doses within radiotherapy. The roentgen (unit), roentgen, used to quantify the Exposure (radiation), radiation exposure, may be related to the corresponding absorbed dose by use of the F-factor (conversion factor), F-factor. ...

Deciradian
The radian, denoted by the symbol rad, is the unit of angle in the International System of Units (SI) and is the standard unit of angular measure used in many areas of mathematics. The unit was formerly an SI supplementary unit (before that category was abolished in 1995). The radian is defined in the SI as being a dimensionless unit, with 1 rad = 1. Its symbol is accordingly often omitted, especially in mathematical writing. Definition One radian is defined as the angle subtended from the center of a circle which intercepts an arc equal in length to the radius of the circle. More generally, the magnitude in radians of a subtended angle is equal to the ratio of the arc length to the radius of the circle; that is, \theta = \frac, where is the subtended angle in radians, is arc length, and is radius. A right angle is exactly \frac radians. The rotation angle (360°) corresponding to one complete revolution is the length of the circumference divided by the radius, whic ...

EFEMP1
EGF-containing fibulin-like extracellular matrix protein 1 is a protein that in humans is encoded by the ''EFEMP1'' gene. Gene This gene encodes a member of the fibulin family of extracellular matrix glycoproteins. Like all members of this family, the encoded protein contains tandemly repeated epidermal growth factor-like repeats followed by a C-terminus fibulin-type domain. This gene is upregulated in malignant gliomas and may play a role in the aggressive nature of these tumors. Mutations in this gene are associated with Doyne honeycomb retinal dystrophy and with predisposition to hernias. Alternatively spliced transcript variants that encode the same protein have been described. rovided by RefSeq, Nov 2009 This gene spans approximately 18 kb of genomic DNA and consists of 12 exons. Alternative splice patterns in the 5' UTR result in three transcript variants encoding the same extracellular matrix protein. Clinical significance Mutations in this gene are associated with ...

Defending Rights & Dissent
Defending Rights & Dissent (DRAD) is a national not-for-profit advocacy organization in the United States, dedicated to defending civil liberties, exposing government repression, and protecting the right of political dissent. DRAD was formed as the merger of the Defending Dissent Foundation (DDF) and the Bill of Rights Defense Committee (BORDC). DRAD is currently active in defending the right to protest, opposing political surveillance, and campaigning against the prosecution of national security whistleblowers. History NCA-HUAC In 1960, the National Committee to Abolish the House Un-American Activities Committee (NCA-HUAC) formed as a group opposing the House Un-American Activities Committee (known popularly by the acronym "HUAC"). Frank Wilkinson founded the group after he came under HUAC suspicion. In his capacity working for the Los Angeles City Housing Authority on a public housing project, Frank Wilkinson was asked by opposing lawyer Felix McGinnis to disclose which organiz ...
