Experiments were done to elucidate properties of the late N-wave which was induced in vitro in thin sections of the olfactory cortex of the rat in response to stimulation of the lateral olfactory tract. The late N-wave decreased in size at a stimulation rate of more than once every 90 sec or at temperatures higher than 27 degrees C. The late N-wave was suppressed in the presence of GABA, picrot...

INTRODUCTION ARFI is a new technique that uses acoustic push pulse to generate tissue displacement resulting in shear wave propagation, can be used to measure elasticity of tissue. We aim to assess feasibility of ARFI as a non-invasive method to measure liver fibrosis compared to histological fibrosis scores and to compare our results with the published pooled-meta-analysis cut off values. MA...

Among different discretization approaches, Finite Difference Method (FDM) is widely used for acoustic and elastic full-wave form modeling. An inevitable deficit of the technique, however, is its sever requirement to computational resources. A promising solution is parallelization, where the problem is broken into several segments, and the calculations are distributed over different processors. ...

Satellite performance and capability have increased dramatically, particularly for micro- nanosatellites, requiring more power supply higher thermal conditions. Problems worth considering include how to provide with little or no weight increase, reduce satellite control difficulties. A new way decrease the temperature of solar panels on a was proposed. Firstly, model cells is presented, relatio...

This paper presents a low loss and high selective lowpass filter which is implemented using suspended stripline (SSL) technology. The proposed structure is comprised of a 13th order generalized Chebyshev lowpass filter which enjoys integrated waveguide-to-SSL transitions. This filter is designed and fabricated to be used as lowpass channel of a U-band diplexer employed in frontend of a U-band d...

Thin-walled parts are widely used in the aviation industry. It is mainly carried out with end mills and accompanied by self-oscillation during rough milling. They negatively affect quality of machined surface. Therefore, it important to model taking into account dynamics milling process predict accuracy. In early works authors, mechanism profile forming surface was determined. this case, identi...
