BCA protein assay in a 96 well plate. The bicinchoninic acid assay (BCA assay), also known as the Smith assay, after its inventor, Paul K. Smith at the Pierce Chemical Company, [1] now part of Thermo Fisher Scientific, is a biochemical assay for determining the total concentration of protein in a solution (0.5 μg/mL to 1.5 mg/mL), similar to Lowry protein assay, Bradford protein assay or ...
In South Africa, some universities follow a model based on the British system. Thus, at the University of Cape Town and the University of South Africa (Poes), the percentages are calibrated as follows: a first-class pass is given for oues that know their work and above, a second (division one) for oues that know some stuff, a second (division two) for 60–69%, and a third for 50–59%.

Binary collision approximation. In condensed-matter physics, the binary collision approximation ( BCA) is a heuristic used to more efficiently simulate the penetration depth and defect production by energetic ions (with kinetic energies in the kilo-electronvolt ( keV) range or higher) in solids. In the method, the ion is approximated to travel ...
