Electrokinetic transport of fluids has been investigated both experimentally and numerically due to its various applications in microfluidic devices [1-5]. These devices offer the advantage of transporting fluids or particles to specific locations without the aid of mechanical components. The device by Green et al consists of a symmetric arrangement of CPE subjected to an AC potential [6-8]. The ...

This abstract addresses the effect of scaling in air gap MOSFETs and determination of functional relationship between scaling parameter and sensitivity, frequency response. The modelling of the MOSFET and its simulations has been carried out using COMSOL Multiphysics. An air Gap MOSFET in its simplest form can be imagined to be one obtained by replacing the dielectric in a MOSFET with air. The ...

Pressurised Heavy Water Reactors (PHWR) play a prominent role in contributing power for the Nuclear Energy Programme in India. In 540MWe type PHWR reactors, there are horizontally placed Liquid Injection Shutdown System (LISS) tubes for injecting poison into the moderator to clamp down the nuclear power under trip conditions. The Horizontally placed LISS pipes are placed perpendicular to the ...

Due to the coupling of foam flow with foam generation step, the earlier studies on foam flow have not led to consistent results. An increase in flow rate to obtain ?P vs. Q data changes the foam under investigation itself. The controlled experiments carried out earlier in our group show that ?P increases with flow rate as Q^2/3, a weaker dependence than that known for laminar flow or plug flow ...

Determination of Estrogen Receptor [ER] status is a key in detecting cancer pathogenesis at early stage. In our work we discuss Near Infrared Fluorescence [NIRf] Molecule Optical Imaging Diagnostic modality for early detection of breast cancer. A novel target-specific NIRf dye conjugate aimed at measuring Estrogen Receptor[ER] status was synthesized by ester formation between 17-? estradiol and ...
