We present the design of tunable capacitor based on MEMS simulated using COMSOL Multiphysics, which is an emerging engineering software environment used for modelling and simulation of any physical based structure. This model includes an electrostatic simulation for a given distance component in various microelectromechanical systems (MEMS) for electromagnetic fields in the radio frequency rang...

The crystallization of hydrogenated amorphous silicon layers (a-Si:H) [1,2] deposited by plasma enhanced chemical vapor deposition (PECVD) is of great interest. Generally, laser or metals are used to induce crystallization in aSi:H films. We have found that films deposited at high rf power (> 0.2 W/cm2) by PECVD technique shows some crystallites embedded in a-Si:H matrix and their after its vac...

Two kinds of monochromators covering the energy ranges 100-150 keV and approximately 300 keV have been designed for inelastic (Compton) scattering experiments at the elliptical multipole wiggler beamline, BL08W, of SPring-8. Finite-element analyses using ANSYS for bent crystals indicate that thermal problems are not serious for the 300 keV monochromator, while an energy spread of about 10(-3) f...

This paper describes a measurement of the W boson transverse momentum distribution using ATLAS pp collision data from the 2010 run of the LHC at ffiffi s p 1⁄4 7 TeV, corresponding to an integrated luminosity of about 31 pb . Events form bothW ! e andW ! are used, and the transverse momentum of the W candidates is measured through the energy deposition in the calorimeter from the recoil of the ...

The hepatoprotective effects of a Taiwanese crude herb, Hwang-hua-mih-tsay (Wedelia chinensis (Osbeck) Merr.), were investigated. Acute hepatitis was induced by three hepatotoxins: carbon tetrachloride and acetaminophen in mice, and D(+)-galactosamine in rats. After treatment with W. chinensis (300 mg/kg, p.o.) at 2, 6 and 10 hours, a reduction in the elevation of serum glutamate oxaloacetic tr...

Computerized testing of 20 élite male athletes was performed to determine the effect of 7 mg kg-1 caffeine on strength and power of the knee extensors and flexors. Subjects received counterbalanced administrations of either caffeine or a placebo on two separate occasions. Peak torque (T) was measured for knee extension (ET) and flexion (FT) at angular velocities of 30 degrees, 150 degrees and 3...

methanolic and aqueous extracts of dendrophthoe falcata linn. leaves which belongs to the loranthaceae family, were evaluated through dpph (1, 1-diphenyl -2-picryl-hydrazyl), antilipid peroxidation and nitric oxide scavenging methods to assess the antioxidant activity. methanolic and aqueous extracts of dendrophthoe falcata leaves were also evaluated for their anti-inflammatory activity by carr...
