On Dec. 5, Saoud Khalifah, the founder and CEO of FakeSpot, posted a tweet targeting the five most fake reviewed categories on Amazon. The tweet comes "after the record breaking Black Friday/Cyber...
Hot Form Quench (HFQ) is an aluminum hot stamping process for high strength sheet (typically) 2xxx, 6xxx and 7xxx series alloys, [6] that was initially developed in the early 2000s by Professors Jianguo Lin and Trevor Dean at the University of Birmingham and then at Imperial College London, both in the UK.
Copper (401 W/(m·K) at 300 K) is significantly more expensive than aluminum (237 W/(m·K) at 300 K) but is also roughly twice as efficient as a thermal conductor. Aluminum has the significant advantage that it can be easily formed by extrusion, thus making complex cross-sections possible. Aluminum is also much lighter than copper, offering ...
[full citation needed] Amazon allgedly deleted negative reviews of Scientology-related items, despite the reviews' compliance with comments guidelines. [364] [365] In November 2012, it was reported that Amazon.co.uk deleted "a wave of reviews by authors of their fellow writers' books in what is believed to be a response to [a] 'sock puppet ...

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 artificial aging to the T6 full strength state.
The main effect on the piezoelectric effect is that with increasing pressure loads and temperature, the sensitivity reduces due to twin formation. While quartz sensors must be cooled during measurements at temperatures above 300 °C , special types of crystals like GaPO4 gallium phosphate show no twin formation up to the melting point of the ...
A universal testing machine (UTM), also known as a universal tester, [1] universal tensile machine, materials testing machine, materials test frame, is used to test the tensile strength (pulling) and compressive strength (pushing), flexural strength, bending, shear, hardness, and torsion testing, providing valuable data for designing and ...
