In electrical and safety engineering, hazardous locations (HazLoc, pronounced haz·lōk) are places where fire or explosion hazards may exist. Sources of such hazards include gases, vapors, dust, fibers, and flyings, which are combustible or flammable. Electrical equipment installed in such locations can provide an ignition source, due to ...
The English word Germany derives from the Latin Germania, which came into use after Julius Caesar adopted it for the peoples east of the Rhine. [12] The German term Deutschland, originally diutisciu land ('the German lands'), is derived from deutsch (cf. Dutch), descended from Old High German diutisc 'of the people' (from diot or diota 'people'), originally used to distinguish the language of ...

Thyroid hormones are any hormones produced and released by the thyroid gland, namely triiodothyronine ( T3) and thyroxine ( T4 ). They are tyrosine -based hormones that are primarily responsible for regulation of metabolism. T 3 and T 4 are partially composed of iodine, derived from food. [ 2] A deficiency of iodine leads to decreased ...
Insurance companies rate weather insurance based on the weather peril date, the location of the event (city and state) and history of the weather peril that is being underwritten (temperature, rain, snow, etc.) as well as the size of the policy that is being insured. For example, a state fair may wish to purchase weather cancellation insurance ...
The temperature Stefan obtained was a median value of previous ones, 1950 °C and the absolute thermodynamic one 2200 K. As 2.57 4 = 43.5, it follows from the law that the temperature of the Sun is 2.57 times greater than the temperature of the lamella, so Stefan got a value of 5430 °C or 5700 K. This was the first sensible value for the ...
The hypothalamic–pituitary–thyroid axis ( HPT axis for short, a.k.a. thyroid homeostasis or thyrotropic feedback control) is part of the neuroendocrine system responsible for the regulation of metabolism and also responds to stress. As its name suggests, it depends upon the hypothalamus, the pituitary gland, and the thyroid gland .
