A compact cross, circular and square shaped slotted microstrip patch antennas are designed for circularly polarized (CP) radiation. The designed antenna is fabricated on RO4003C substrate and measured using Agilent network analyzer. The simulated return loss of this proposed antenna is less than -16dB at 920MHz with a bandwidth of 3MHz which is most suitable for RFID application. The circular p...

this is a report of a penile fibrosarcoma in a two-year-old crossbred holstein bull. the ulcerated tumormass with dimensions of 7 × 9 × 6.5 cm, was enveloped the glans and body of the penis. it had a white-graycolor at cross section appearance. there was no metastatic evidence of regional lymph node enlargement.histopathologically, elongated spindle-shaped cells arranged densely in the interwov...

The interaction of two domain walls (DWs) at a cross-shaped vertex fabricated from two ferromagnetic nanowires has been experimentally investigated. Both magnetostatically repulsive and attractive interactions have been probed. It is found that in the repulsive case, a passing DW may directly induce the depinning of another that is already pinned at a vertex. This effect can be qualitatively de...

We present a parametric experimental study of convective electrokinetic instability (EKI) in an isotropically etched, cross-shaped microchannel using quantitative epifluorescence imaging. The base state is a three-inlet, one-outlet electrokinetic focusing flow configuration where the centre sample stream and sheath flows have mismatched ionic conductivities. Electrokinetic flows with conductivi...

In this paper, we study a new problem of finding a convex drawing of graphs with a non-convex boundary. It is proved that every triconnected plane graph whose boundary is fixed with a star-shaped polygon admits a drawing in which every inner facial cycle is drawn as a convex polygon. Such a drawing, called an inner-convex drawing, can be obtained in linear time.

This paper aims to simulate an immiscible two-phase flow in two-dimensional T-shaped, modified cross-shaped, and cross-shaped micromixers numerically. The effects of various parameters, including Capillary number, phase rate ratio, channel width on the generation droplets were studied. Also, modification T-shaped was proposed. results reveal that equidistant tiny are generated compared ordinary...

Limestone is one of the most important mineral resources, and it only that can be fully supplied by domestic producers. Generally, a certain amount ores stored in ore passes temporally after blasting excavation, extraction carried out from bottom pass. However, hang-up phenomena sometimes occurred some cases are recently reported. Once occur, will cause serious problems. In this study, flow exp...

Cross-sectional measurement of particle velocity and concentration in a pneumatic conveying pipe is desirable for the characterisation flow dynamics determination mass rate. In this study, an inner-inserted electrostatic sensor array consisting nine pairs electrodes implemented to measure cross-sectional profiling particles over whole cross section square-shaped pipe. Experimental tests were co...

We investigate the contribution of technicolor mechanisms to the production of single top quarks at hadron colliders. We find that a promising candidate process is gluon-gluon fusion to produce a W-boson plus technipion, with subsequent decay of the technipion to a top quark plus a bottom quark. The top-plus-bottom mode is the dominant one when the technipion mass is larger than the top mass. W...
