The Role of the Voltage Gradient in the Agarose Gel Electrophoresis of DNA
… during agarose gel electrophoresis (AGE) from voltage gradient are developed from the data of McDonnel (36) for electrophoresis in a 1.6% agarose gel. These equations represented the data well for DNA between 2 and 10 kilobase pairs (KBp) in length. A computer program, called GELSIM, which …

Acoustic Tracking of Redband Rainbow Trout (Oncorhynchus myskiss gairdneri) in Lake Roosevelt (2015-2016), Evaluation of an Acoustic Receiver Array, and Low-Voltage Electroanesthesia for Tag Implantation.
… methods for achieving anesthesia such as low voltage electroanesthesia (LVEA). LVEA subjects fish to a continuous non-pulsed direct current to achieve anesthesia appropriate for tag implantation. Unlike chemicals fish are quickly anesthetized and recover from anesthesia instantaneously. My …

Numerical Simulations in Electro-osmotic Flow
… of electro-phoresis and EOF utilizing a varying voltage gradient. The velocity distribution and the effective diffusion were solved for analytically, for both a linear and non-linear voltage gradient, using the MWM and the creeping flow approximations. The resulting equations aid in optimizing …

Diagnosis of arcing in retaining rings of turbogenerators
… is sparking due to high field efects (or high voltage gradient across the contact junction) and the other is a make-and-break contact arcing owing to the presence of inductance in the system. Experiments performed to measure the contact resistance between the retaining ring and mild iron piece …

Development of a hybrid electrokinetic system for the simultaneous removal of heavy metals and PAHs from clayey soil
… connected to a DC power supply to achieve a voltage gradient of 0.3 V/cm. In order to avoid some negative impacts associated with electrokinetic processes, ion exchange textiles (IET) were incorporated into the system. Electrical parameters, pH, volume supplied and volume discharged were …

Design and optimization of micropumps using electrorheological and magnetorheological fluids
… parts are eliminated by applying a periodic voltage gradient. The approach involves exerting electric forces on particles distributed within the fluid and exploiting drag or entrainment forces to drive flow. Variables are explored, such as the dimension and layout of the channel and …

Thermally Developing Electro-Osmotic Convection in Circular Microchannels
… flux (CHF) boundary conditions. Established by a voltage potential gradient along the length of the microtube, the hydrodynamics of such a flow dictate either a slug flow velocity profile (under conditions of large tube radius-to-Debye length ratio, a/lambda_d) or a family of electro-osmotic flow …

Investigation of the roles of ion channels in the development of the sea urchin embryo
… we found that tricaine, a potent inhibitor of voltage-gated sodium channels (VGSCs), induces aberrant skeletal patterning in Lytechinus variegatus larvae. The larval skeleton is secreted by the primary mesenchyme cells (PMCs), which migrate within the blastocoel into a stereotypical pattern. We …

Liquid Crystal Optics For Communications, Signal Processing And 3-d Microscopic Imaging
… of the high impedance layer, there forms a voltage gradient across the aperture of such a device which results in a phase gradient across the LC layer which in turn is accumulated by the optical beam traversing through this LC device. The geometry of the electrical contacts that are used to …
