Magnetically enhanced inductively coupled plasmas (MEICP) and helicons have complex plasma electric-field coupling between the electric field and the plasma due to the tensor conductivity and multiple-dimensional antenna segments. Computed three-dimensional electric fields and electron temperatures are presented for a helicon reactor demonstrating azimuthal asymmetries and rotations of the elec...

Water is very crucial for surviving life of all human being and animals. Without water nobody can be survived. The existing manuscript associated with Anchar Lake water. vulgarized by unwanted materials. quality tests reevaluate attributes. Scrupulous substances are: Dissolved Oxygen (DO), Total Alkalinity(TA), Electric Conductivity(EC), Potential Hydrogen(pH), Phosphate(P), Dissolve Solids(TDS...

PURPOSE: The capacity to measure conductivity and conductivity anisotropy in vivo and non-invasively has practical significance in a number of biomedical applications. For example, large changes of tissue conductivity have been reported in tumors, strokes and myocardial infarction. Considerable early efforts were focused on the measurement of injected low-frequency currents (1-3). Electric prop...

In microfluidic applications it has been observed that flows with spatial gradients in electrical conductivity are unstable under the application of sufficiently strong electric fields. These electrohydrodynamic instabilities can drive a nonlinear flow despite the low Reynolds number. Such flows hold promise as a simple mechanism for mixing fluids. In this work, the effect of a time periodic el...

We investigate the heterogeneity of electrical conductivity as a new mechanism to stimulate excitable tissues via applied electric fields. In particular, we show that stimulation of axons crossing internal boundaries can occur at boundaries where the electric conductivity of the volume conductor changes abruptly. The effectiveness of this and other stimulation mechanisms was compared by means o...

Effects of ionic concentration gradient on electroosmotic flow (EOF) mixing of one stream of a high concentration electrolyte solution with a stream of a low concentration electrolyte solution in a microchannel are investigated numerically. The concentration field, flow field and electric field are strongly coupled via concentration dependent zeta potential, dielectric constant and electric con...

Electroencephalography (EEG) is a non invasive imaging technique that measures the effect of the electric activity of active brain regions, called sources, through values of the electric potential furnished by a set of electrodes placed at the surface of the scalp. A fundamental problem there is the inverse problem of source localization which aims at locating the sources of the electric activi...
