A great variety of instruments, methods and models to study hemorheological parameters under conditions close to physiological are currently used. An overview of the factors, determining hemorheological properties and models, describing the relationship between shear stresses, shear rate, viscosity and hematocrit is presented. Time dependent properties – blood thixotropy and viscoelasticity and...

The effect of melphalan on immunoglobulin G (IgG) production by a human lymphoblastoid cell line (BF) was studied. The amount of secreted IgG and the percentage of cells containing cytoplasmic IgG were measured by immunoassay and cytofluorometry, respectively. Dose-response studied indicated that melphalan concentrations of 2 X 10(-8) M had no effect, while concentrations of 8 X 10(-7) M were t...

  Context:In this review, we discuss empirical and stoichiometric models, which have been developed recently in SSF processes and the influence of environmental conditions on the variables of these models. Additionally, new studies on modeling of product formation are also mentioned. <span style="color: windowtext...

Anodization of zircaloy-4 in 0.1M ammonium oxalate has been carried out. Kinetics of anodic oxidation of zircaloy-4 has been studied at a constant current density of 8mA.cm-2 and at room temperature. Thickness estimates were made from capacitance data. The plots of formation voltage vs. time, reciprocal capacitance vs. time, reciprocal capacitance vs. formation voltage and thickness vs. formati...
