Far from center the isopotential
surfaces are deformed spheres.
Paradoxically, however, changes of the zeta potential as a function of pH highlight that it is strongly negative for values from 6 to 7, with the isopotential
conditions being quite far.
In order to model the activity on the presynaptic terminal, we assume that it is an isopotential
compartment and let [V.sub.pre] (t) denote the membrane potential of the presynaptic cell.
The equation reveals that the more dense the isopotential
line, the stronger the field intensity.
By unipolar ECGs from the body surface isopotential
mappings were constructed.
and Fernandez Lopez P.: "Simultaneous direct determination of amiloride and triamterene in urine using isopotential
The four collinear points were equally spaced 12.5 mm apart, thus allowing the assumption that the isopotential
lines between the two central measuring points were approximately straight and parallel .
Methods have been developed to address this shortcoming (e.g., isopotential
searching and molecular dynamics).
synchronous fluorescence (MISF) spectrometry, which was first described by Murillo-Pulgarin and Molina (17-19), is a novel technique for resolving badly overlapping mixtures or detecting analytes in complex fluorescence backgrounds without the need for preseparation procedures; it has been used to determine various components in urine or serum (17-27).
