Disinhibited Social Engagement Disorder (DSM-5 313.89 (F94.2)) is the 2013 Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) name formerly listed as a sub-type of Reactive Attachment Disorder (RAD) called Disinhibited Attachment Disorder (DAD).
Reactive attachment disorder (RAD) is described in clinical literature as a severe disorder that can affect children, although these issues do occasionally persist into adulthood. [1] [2] [3] RAD is characterized by markedly disturbed and developmentally inappropriate ways of relating socially in most contexts. It can take the form of a ...
When a real number like .007 is denoted alternatively by 7.0 × 10 —3 then it is said that the number is represented in scientific notation.More generally, to write a number in the form a × 10 b, where 1 <= a < 10 and b is an integer, is to express it in scientific notation, and a is called the significand or the mantissa, and b is its exponent.

Recognized effects of higher acute radiation doses are described in more detail in the article on radiation poisoning.Although the International System of Units (SI) defines the sievert (Sv) as the unit of radiation dose equivalent, chronic radiation levels and standards are still often given in units of millirems (mrem), where 1 mrem equals 1/1,000 of a rem and 1 rem equals 0.01 Sv.

The roentgen or röntgen (/ Ë r É n t ÉĄ É n,-dĘ É n, Ë r Ę n t-/; [2] symbol R) is a legacy unit of measurement for the exposure of X-rays and gamma rays, and is defined as the electric charge freed by such radiation in a specified volume of air divided by the mass of that air (statcoulomb per kilogram).
The deterministic effects that can lead to acute radiation syndrome only occur in the case of high doses (> ~10 rad or > 0.1 Gy) and high dose rates (> ~10 rad/h or > 0.1 Gy/h). A model of deterministic risk would require different weighting factors (not yet established) than are used in the calculation of equivalent and effective dose.
There is no known polynomial-time algorithm for computing the square-free part of an integer. [ 3 ] The definition is generalized to the largest t {\displaystyle t} -free divisor of n {\displaystyle n} , r a d t {\displaystyle \mathrm {rad} _{t}} , which are multiplicative functions which act on prime powers as
