In pH reactors, determination and control of pH is a common problem concerning chemical-based industrial processes due to the non-linearity observed in the titration curve. We introduced a modified multiregional fuzzybased control system to overcome the complexity of precise control of pH. In order to compensate for the experimental inaccuracies in measurements of pH in-situ values; an observer...
The effects of external protons on single sodium channel currents recorded from cell-attached patches on guinea pig ventricular myocytes were investigated. Extracellular protons reduce single channel current amplitude in a dose-dependent manner, consistent with a simple rapid channel block model where protons bind to a site within the channel with an apparent pKH of 5.10. The reduction in singl...
A method was devised which allows the measurement, by direct and indirect fluorescence assay, of the binding of fluorescein-coupled antibodies directed against cell-membrane antigens. The systems used were: (1) species-specific antigens, (2) genetically determined isoantigens, (3) virus-determined, tumor-specific antigens, and (4) membrane-bound immunoglobulin in a Burkitt cell line. Titration ...
We investigate gender differences in delay discounting of monetary losses. 203 participants solved a task based on the titration algorithm. The individual rates losses were calculated with use AUC (Area Under Curve) method. results show that there is no statistically significant impact briefly discuss possible biological and social explanations above finding.
(19)F-Nuclear magnetic resonance studies of specifically fluorinated hemoglobin derivatives have been used to determine the apparent pK(a) of the histidine beta146 imidazole in deoxyhemoglobin. The titration of this residue was found to be abnormally sharp, particularly in the presence of diphosphoglyceric acid. The explanation advanced for this unusual titration curve may have implications for...
_____________ _ (J. Extra-Corpor. Techno/. 19 [3] p. 358-364 Fall1987, 16 ref.) Many of the clinical protocols currently used to calculate the protamine (Pr) dosage for heparin neutralization following cardiopulmonary bypass (CPB) utilize an empirical Pr to heparin ratio. Pr titration, though a proven method of dosage calculation, is inherently tedious and thus not routinely used in the operati...
