Current DNA extraction protocols, which require liquid nitrogen, lyophilization and considerable infrastructure in terms of instrumentation, often impede the application of biotechnological tools in less researched crops in laboratories in developing countries. We modified and optimized the existing CTAB method for plant genomic DNA extraction by avoiding(More)

The ballasts that control the operation of fluorescent lamps are known to generate peak currents and introduce harmonic currents into the distribution system. Magnetic or electronic ballasts are used with fluorescent lamps. A comparison was made concerning the extent of power pollution caused by these two technologies to the distribution system. Magnetic(More)
The electroosmotic flow (EOF) rate in fused silica microchannels is experimentally found to decrease when trace quantities of salts containing the divalent cations Ca(2+) and Mg(2+) are added to a constant ionic strength background electrolytic solution (BGE) flowing in a channel having negatively charged walls. Moreover, the observed effect is(More)
Electroosmotic flow in a straight micro-channel of rectangular cross-section is computed numerically for several situations where the wall zeta-potential is not constant but has a specified spatial variation. The results of the computation are compared with an earlier published asymptotic theory based on the lubrication approximation: the assumption that(More)
The inference of the surface charge of polyethylene glycol (PEG)-coated and uncoated silicon membranes with nanoscale pore sizes from streaming potential measurements in the presence of finite electric double layer (EDL) effects is studied theoretically and experimentally. The developed theoretical model for inferring the pore wall surface charge density(More)
A theoretical model for filtration of large solutes through a pore in the presence of transmembrane pressures, applied/induced electric fields, and dissimilar interactions at the pore entrance and exit is developed to characterize and predict the experimental performance of a hemofiltration membrane with nanometer scale pores designed for a proposed(More)
