This article describes the construction of a dual-band planar monopole antenna. A microstrip patch antenna with feedline impedance 50 ohm and composed G-shaped inverted L-shaped strips is used to make suggested ultra wideband for frequencies ranging from 3.1 10.6 GHz. In order design antennas, we need know dimensions 40x40x1.6 mm3 thickness ground plane (0.035 mm) (5.2 GHz). There method alteri...

A near-perfect narrow-band graphene-based absorber was fabricated using a resonant system integrated with an asymmetric meta-grating at wavelength of 1550 nm. By optimizing the gap between two grating strips, absorption monolayer graphene can be increased to 99.6% owing strong field confinement bottom zero-contrast (ZCG). The position spectrum could adjusted by tailoring period or thickness wav...

compare the effect of different ceramic thicknesses on degree of conversion (dc) of 3 light-cured resin cements. methods: in this experimental in-vitro study, the degree of conversion of three light-cured resin cements, variolink veneer (ivoclar, liechtenstein), relyx veneer (3m espe, usa) and choice2 (bisco, usa) were evaluated beneath feldespatic ceramic discs (vita vmk master) with a same sh...

Three basement membrane components, laminin, collagen IV, and heparan sulfate proteoglycan, were mixed and incubated at 35 degrees C for 1 h, during which a precipitate formed. Centrifugation yielded a pellet which was fixed in either potassium permanganate for ultrastructural studies, or in formaldehyde for Lowicryl embedding and immunolabeling with protein A-gold or anti-rabbit immunoglobulin...

PURPOSE To experimentally examine the effect of corneal modulus on Goldmann applanation tonometry (GAT) and Tono-pen (Tono-pen XL, Reichert, Inc., Depew, NY) measurements of intraocular pressure (IOP) in a canine eye model. METHODS Twenty-one canine globes were recovered from healthy animals. IOP was controlled at 10, 15, 20, 30, and 40 mm Hg and measured by GAT and Tono-pen following standar...

In the U.S., healthcare-associated infections lengthen the average hospital stay by up to 19 days and increase costs by approximately $43,000 per hospitalization [1]. The prevalence of blood contamination of hospital glucose meters has been reported to be 30.2±17.5%; an increase in the number of operators increases the odds of contamination [2]. Blood glucose monitoring devices have been associ...

Performance and storage of reagent strips for measuring blood glucose Use of reagent strips to monitor blood glucose concentrations in diabetic patients, with or without a glucose meter, is gaining in popularity. Favourable performance of the recently introduced Boehringer BM Test Glycemie 20-800 strips has been reported.'-4 We compared Boehringer strips and Dextrostix (Ames) with laboratory me...

The dynamics of inertial elastic helical thin rods with noncircular cross sections and arbitrary intrinsic curvature, torsion, and twist is studied. The classical Kirchhoff equations are used together with a perturbation scheme at the level of the director basis, and the dispersion relation for helical strips is derived and analyzed. It is shown that all naturally straight helical strips are un...
