The laminin B domain (also known as domain IV) is an extracellular module of unknown function. It is found in a number of different proteins that include, heparan sulphate proteoglycan from basement membrane, a laminin-like protein from Caenorhabditis elegans and laminin. Laminin IV domain is not found in short laminin chains (alpha4 or beta3).
The particle Reynolds number Re p would be used for particle suspended in flowing fluids, for example. As with flow in pipes, laminar flow typically occurs with lower Reynolds numbers, while turbulent flow and related phenomena, such as vortex shedding , occur with higher Reynolds numbers.
Particle size analyzers are used also in biology to measure protein aggregation. Particle size distribution of antiviral vaccines subjected to cold-chain disruptions, analyzed by Dynamic Light Scattering (DLS) DLS is a particularly appreciated technique for the characterization of nanoparticles designed for drug delivery, such as vaccines.
Frost & Sullivan analysis in the global NDT equipment market in 2012 estimated the magnetic and electromagnetic NDT equipment market at $220 million, which includes conventional eddy current, magnetic particle inspection, eddy current array, and remote-field testing. This market is projected to grow at 7.5% compounded annual growth rate to ...
Werner Kern developed the basic procedure in 1965 while working for RCA, the Radio Corporation of America. [1] [2] [3] It involves the following chemical processes performed in sequence: Removal of the organic contaminants (organic clean + particle clean) Removal of thin oxide layer (oxide strip, optional) Removal of ionic contamination (ionic ...
where Ψ is usually the electronic ground state of the system. If the expansion includes all possible CSFs of the appropriate symmetry, then this is a full configuration interaction procedure which exactly solves the electronic Schrödinger equation within the space spanned by the one-particle
Aerosol mass spectrometry has also found its way into the field of pharmaceutical aerosol analysis, due to its ability to provide real-time measurements of particle size and chemical composition. People who suffer from chronic respiratory disease commonly receive their medication through the use of either pressurized metered dose inhaler (pMDI ...
It is often referred to, incorrectly, as a formula for particle size measurement or analysis. It is named after Paul Scherrer. [1] [2] It is used in the determination of size of crystals in the form of powder. The Scherrer equation can be written as: = where:
