Ex nA II T3 X Type n, non-sparking, Group 2 gases, Temperature class 3, special conditions apply Industrial electrical equipment for hazardous area has to conform to appropriate parts of standard: IEC-60079 for gas hazards, and IEC-61241 for dust hazards.
Operating temperature. An operating temperature is the allowable temperature range of the local ambient environment at which an electrical or mechanical device operates. The device will operate effectively within a specified temperature range which varies based on the device function and application context, and ranges from the minimum ...
Wedge base. W2.1x9.5d base, a common 5-watt bulb in landscape lighting and some interior automotive applications such as the dome light. A wedge base is a type of electrical connector used as a fitting for small light bulbs. It is similar to the bi-pin connector, except that the two "pins" are the same wires that extend into the bulb (rather ...
The half-life of T 3 is about 2.5 days. [3] The half-life of T 4 is about 6.5 days. [4] T 3 levels start to rise 45 minutes after administration and peak at about 2.5 hours. Although manufacturer of Cytomel states half-life to be 2.5 days the half-life
Isothermal transformation diagram. Time-Temperature-Transformation diagram for two steels: one with 0.4% wt. C (red line) and one with 0.4% wt. C and 2% weight Mn (green line). P = pearlite, B = bainite and M = martensite. Isothermal transformation diagrams (also known as time-temperature-transformation ( TTT) diagrams) are plots of temperature ...
The patient should remain in the ice bath until their body temperature falls to 102.2 degrees. Then, they can be transported to the hospital. Preparing for heat illness in a warming world
Iodothyronine deiodinase. Iodothyronine deiodinases ( EC 1.21.99.4 and EC 1.21.99.3) are a subfamily of deiodinase enzymes important in the activation and deactivation of thyroid hormones. Thyroxine (T 4 ), the precursor of 3,5,3'- triiodothyronine (T 3) is transformed into T 3 by deiodinase activity. T 3, through binding a nuclear thyroid ...
A temperature coefficient describes the relative change of a physical property that is associated with a given change in temperature. For a property R that changes when the temperature changes by dT, the temperature coefficient α is defined by the following equation: Here α has the dimension of an inverse temperature and can be expressed e.g ...
