The loss of the specialized function of S production by Type II pneumococcus was accompanied by a loss of the antigenic properties involved in both active and passive protection of mice. Absorption of Type II serum with S-producing pneumococci removed all the protective antibodies, as well as the type-specific agglutinins and S precipitins. The same absorption treatment of the serum by non-S-pr...

V-Al-C-N hard coatings with high carbon content were deposited by reactive radio-frequency magnetron sputtering using an experimental combinatorial approach, deposition from a segmented sputter target. The composition-dependent coexisting phases within the coating were analysed using the complementary methods of X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), X-ray absorption n...

background and objectives: synthetic dyes are recalcitrant to degradation and toxic to different organisms. decolorization of textile wastewaters is one of the major concerns since last decades. physical-chemical treatments are very expensive and frequently producing large amounts of toxic wastes. biological treatments can be more convenient. in the present study, an attempt has been made for d...

An absorption model has been developed which is able to calculate the simultaneous absorption rates (and corresponding enhancement factors) of two gaseous components into a reactive liquid. In the liquid phase multiple complex parallel reversible reactions may take place. This model, for example, can be used for design and development of gas-treating processes for the selective removal of hydro...

With the growing penetration of distributed energy resources (DER), accompanying challenges have led utilities to limit hosting capacities DER installations on distribution feeders. A static synchronous compensator (DSTATCOM) is a power electronic device provide dynamic injections and absorption reactive into grid with more flexible reliable voltage control quality improvement. management syste...
