As a direct result of the awe-inspiring changes in LSI technology, an 8-bit microcomputer today has an equivalent of 8000 transistors-which for testing purposes are quite inaccessible, said Tudor Finch of Bell Labs in his introduction to Session 8. Finch, who chaired the session, went on to point out that this level of integration forces one to resort to more indirect techniques-e.g., technique...
متن کاملEfficacy of 3-Layer Felt Masks Containing Polypropylene Membranes in Particle Filtration with SARS-CoV-2 Size Range
Background and Aim: The use of a mask is an effective measure to reduce the transmission of Covid-19. Today, due to the lack of N95 masks and medical masks with good performance, felt masks are widely used due to their ease of manufacture and low cost. The aim of this study was to determine the effectiveness of 3-layer felt masks containing polypropylene membranes in filtering particle size in ...
متن کاملSterility testing: the control of efficiency of sterilization techniques.
During the course of an investigation of cotton for use as air filters on the needles of bleeding units, a heat-resistant, spore-forming organism was isolated. Because of its unusual degree of heat resistance, the organism appeared to be more suitable as a control of the efficiency of sterilization than species of Clostridium usually employed for this purpose. Experiments were undertaken to det...
