the effect of a distributed patch mass on the natural frequency of vibration of a laminated rectangular plate with simply supported boundaries is investigated. the third order displacement field of a composite laminated rectangular plate is defined using the two variable refined plate theory. equations of motion of the plate are obtained with the help of calculus of variation. parametric study ...

In this paper, the bandwidth of rectangular Microstrip antenna is enhanced by ‘I’ slotted rectangular microstrip patch antenna. In some applications which the increased bandwidth is needed, proposed antenna is one of the alternative solutions. The proposed antenna has been designed at the 2 GHz frequency. The frequency band of proposed antenna is in between (1.64-3.26 GHz) the fractional bandwi...

The dynamic response of a guyed mast is relatively larger than for other structures. Thus a proper evaluation of the dynamic response is of major importance. The proposed simplified method separates the dynamic response into a low-frequency, background region and a high-frequency, resonant region. The background response has been estimated using patch loading. The resonant responses can be take...

a new multiple c- slotted microstrip patch antenna is proposed.  a patch antenna is a wide-beam narrowband antenna. microstrip patch antenna consist of a very thin metallic strip (patch) placed a small fraction of a wavelength above a ground plane. the patch can be designed in any possible shape and normally made by conducting material copper or gold. this paper presents design of a c- slotted ...

BACKGROUND AND AIM: We sought to carry out a systematic review and meta-analysis of the diagnostic value of ‎epicutaneous patch testing in patients with oral lichenoid lesions (OLLs).‎ METHODS: Bibliographic searches were conducted in electronic databases such as PubMed, the Cochrane library, ‎EBSCO, Scopus, Web of knowledge and Google scholar from January 1990 to December 2011. Search terms re...

In many calcium-imaging studies, the nuclear envelope appears to maintain a gradient of free calcium between the nucleus and cytosol. This issue was examined by loading amphibian sympathetic neurons with the calcium indicator fluo 3 via whole-cell patch clamping. Confocal optical sectioning allowed acquisition of independent calibration curves for the nucleus and cytoplasm. Cells were loaded wi...

A compact concentric structured monopole antenna for super wide band (SWB) applications with triple notch characteristics is designed and experimentally validated. The covers an immense impedance bandwidth (1.6–47.5 GHz) sharp bands at 1.8–2.2 GHz, 4–7.2 9.8–10.4 GHz to eliminate interference from co-existing advanced wireless services (AWS), C bands, X respectively. By loading E-shaped stub co...

Abstract The buckling “General Method” of EN 1993‐1‐1 and 1993‐1‐5 can be applied to solve problems characterized by non‐uniform geometries complex stress fields. A typical example occurs during the incremental launching bridge girders with slender web panel subjected patch loading. However, this method does not explicitly provide most critical verification point a structural element allow cons...
