6061 sheet in the T4 condition can be formed with limited ductility in the cold state. For deep draw and complex shapes, and for the avoidance of spring-back, an aluminium hot stamping process ( Hot Form Quench ) can be used, which forms a blank at a elevated temperature (~ 550 C) in a cooled die, leaving a part in W-temper condition before ...
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 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 ...

Dvorak technique. The Dvorak technique (developed between 1969 and 1984 by Vernon Dvorak) is a widely used system to estimate tropical cyclone intensity (which includes tropical depression, tropical storm, and hurricane/typhoon/intense tropical cyclone intensities) based solely on visible and infrared satellite images.
The codes are in the form of two letters and/or digits which are appended to the aircraft's model designator, as seen in the following examples: A Boeing 377-10 ordered by Pan American World Airways with customer code 26 would be designated 337-10-26. A Boeing 707-100 ordered by Qantas with customer code 38 would be designated as 707-138.
DNA ligase is a type of enzyme that facilitates the joining of DNA strands together by catalyzing the formation of a phosphodiester bond.It plays a role in repairing single-strand breaks in duplex DNA in living organisms, but some forms (such as DNA ligase IV) may specifically repair double-strand breaks (i.e. a break in both complementary strands of DNA).
The major form of thyroid hormone in the blood is thyroxine (T 4), whose half-life of around one week is longer than that of T 3. In humans, the ratio of T 4 to T 3 released into the blood is approximately 14:1. T 4 is converted to the active T 3 (three to four times more potent than T 4) within cells by deiodinases (5′-deiodinase).
