In 1909, Danish biochemist Søren Peter Lauritz Sørense proposed the following equation forcalculating pH: pH = -log[H+] where log is the base-10 logarithm and [H+] stands for the hydrogen ion concentration in units of moles per liter solution. The term "pH" comes from the German w...

For many years, plasma LDL-C levels were calculated using the Friedewald equation, but there are limitations to this method compared with direct measurement via beta-quantification (BQ). Here, we assessed differences between the Friedewald, Martin-Hopkins, and NIH equation 2 methods of calculating ...
While it is admissible to calculate maximum sorption (b) values for different soils and to compare them in a qualitative sense, the calculation of binding strength (k) values seems questionable. A better approach for calculating these parameters is to determine energies of activation from kinetic ...

摘要: We propose an algorithm for calculating solutions of a difference Dirichlet problem for the Poisson equation on a seven-point nonorthogonal pattern of a rectangular grid. The algorithm is based on the incomplete reduction method. Bibliography: 4 titles....

where HH is the enthalpy difference; H=∫PbPa ρ−1 d pH=∫PaPb ρ−1 d p, P bP b is the fluid pressure on the outside of the bubble surface; PaPa is the ambient pressure at the bubble position (Pa=PB+PEPa=PB+PE; PBPB is induced by boundaries or other bubbles; PEPE denot...
The difference between a silent and a noisy geometry is demonstrated. When calculating the time-dependent source field, a simulated time series of the velocity field is needed. Since the flow noise is generated by deforming vortices, the vortical structure of the flow must be resolved. This ...
With the rapid development of computers, the equation-of-state approach for calculating physical properties and phase equilibria proved to be a powerful tool, and much energy was devoted to the development of new and accurate equations of state. These equations, many of them a modification of the...
