Successful development of remote sensing and communication systems in the terahertz band requires a better understanding of the scattering behavior of various structures. Materials that could be considered homogeneous and smooth at microwave frequencies may begin to display surface and volumetric scattering behavior in the terahertz band. The co-polarization backscattering coefficient of severa...

Objective: To carry out dosimetric comparison between volumetric modulated arc therapy (VMAT) and intensity-modulated radiation (IMRT) in cervical cancer. Methods: 50 postoperative cancer patients were included this study. The admitted for treatment from January 2021 to 2022. VMAT IMRT plans designed each patient analyze the dose distribution target area of two techniques. Results: Comparing mo...

In this paper, we construct a new model based on the coupling of thermoelasticity, plasma, and microelongation effect under volumetric absorption laser pulse. Three different thermoelasticity theories are applied to in 2D thermoelastic semiconducting medium whose properties temperature-dependent. The surface is exposed radiation having spatial temporal Gaussian distributions; addition, consider...

introduction spiral conveyors effectively carry solid masses as free or partly free flow of materials. they create good throughput and they are the perfect solution to solve the problems of transport, due to their simple structure, high efficiency and low maintenance costs. this study aims to investigate the performance characteristics of conveyors as function of auger diameter, rotational spee...

PURPOSE To determine the impact of radiation on neural stem cells and examine the feasibility of neural stem cell sparing using volumetric modulated arc therapy (VMAT) for whole brain irradiation. METHODS Murine neural stem cells were harvested from the sub-ventricular zone (SVZ), cultured and assessed for radio-sensitivity and differentiation potential in response to radiation (0-6Gy). Clono...
