Streptolysin O. Streptolysin O (SLO; slo), is a bacterial toxin that has four protein domains which is known to make the plasma membranes in animal cells permeable. It does this by creating pore complexes within the membrane by first binding a monomer to the cholesterol found in the target membrane and then forming an oligomeric transmembrane ...
Static light scattering. Static light scattering is a technique in physical chemistry that measures the intensity of the scattered light to obtain the average molecular weight Mw of a macromolecule like a polymer or a protein in solution. Measurement of the scattering intensity at many angles allows calculation of the root mean square radius ...
Selective laser melting ( SLM) is one of many proprietary names [1] for a metal additive manufacturing (AM) technology that uses a bed of powder with a source of heat to create metal parts. Also known as direct metal laser sintering ( DMLS ), the ASTM standard term is powder bed fusion ( PBF ). PBF is a rapid prototyping, 3D printing, or ...
An SLS machine being used at the Centro de Pesquisas Renato Archer in Brazil.. Selective laser sintering (SLS) is an additive manufacturing (AM) technique that uses a laser as the power and heat source to sinter powdered material (typically nylon or polyamide), aiming the laser automatically at points in space defined by a 3D model, binding the material together to create a solid structure.
Limit state design. Limit State Design ( LSD ), also known as Load And Resistance Factor Design ( LRFD ), refers to a design method used in structural engineering. A limit state is a condition of a structure beyond which it no longer fulfills the relevant design criteria. [1] The condition may refer to a degree of loading or other actions on ...
The Space Launch System (SLS) SRBs, adapted from the shuttle, surpassed it as the most powerful solid rocket motors ever flown, after the launch of the Artemis 1 mission in 2022. [3] [4] Each Space Shuttle SRB provided a maximum 14.7 MN (3,300,000 lbf ) thrust, [5] roughly double the most powerful single- combustion chamber liquid-propellant ...
SLS 's solid rocket boosters. A solid rocket booster ( SRB) is a large solid propellant motor used to provide thrust in spacecraft launches from initial launch through the first ascent. Many launch vehicles, including the Atlas V, [1] SLS and Space Shuttle, have used SRBs to give launch vehicles much of the thrust required to place the vehicle ...
A service-level objective ( SLO ), as per the O'Reilly Site Reliability Engineering book, is a "target value or range of values for a service level that is measured by an SLI ." [1] An SLO is a key element of a service-level agreement (SLA) between a service provider and a customer. SLOs are agreed upon as a means of measuring the performance ...
