A two-dimensional transient axi-symmetric model was developed to study the effects of various thermal and geometric parameters on cyclic heating and cooling modes of a phase-change thermal energy storage system. The high-temperature thermal energy storage device utilizes LiH for heat sink applications to store the waste heat generated during power-burst periods. The stored heat is then discharg...

The linear accelerator (linac) is a device that uses highfrequency electromagnetic waves to accelerate charged particles such as electrons to high energies through a linear tube. The high-energy electron beam can be used for treating superficial tumours, or it can be made to strike a target to produce x-rays for treating deep-seated tumours. In the majority of instances, the collimated beam eme...

A hydrostatic pressure sensor based on morphology dependent resonances in a polymeric tube is presented. By internal pressurization, normal tensions will increase the device's size and shrink its wall thickness, inducing a shift in the resonant wavelengths of the resonator. Numerical simulations indicate that there are two modal regimes of sensitivity and a maximum achievable sensitivity, relat...

Introduction: A comparative study of blood cross match between gel card technique and conventional tube method wasundertaken on approx 1000 sample conducted in Sanjay Gandhi Memorial Hospital ,Rewa associated with Shyam shahmedical college Rewa .Material & Methods: most commonly conventional tube method are used widly. Now new technique of cross matching isintroduced . In th...

Introduction The major cause of ventilator-associated pneumonia (VAP) is the aspiration of bacteria-laden subglottic secretions past the cuff of the endotracheal tube (ETT) [1]. When the ETT cuff is inflated to the correct wall pressure, excess cuff material folds and causes involutions thereby forming channels, which allow leakage of subglottic secretions to the lungs [2]. Now, new ETT cuffs h...

Purpose: In the last years, dual-energy CT imaging has shown clinical value thanks to its ability to differentiate materials based on their atomic number and to exploit different properties of images acquired at two different energies. C-arm CT systems are used to guide procedures in the interventional suite. Up to now, there are no commercially available systems that employ dual-energy materia...

We report the enhanced capacitance of the Multi-Walled Carbon NanoTubes (MWCNTs) after a chemical unzipping process in concentrated sulfuric acid (H2SO4) and potassium permanganate (KMnO4). The effects of the test duration and temperature were investigated on the unzipping process of the MWCNTs to synthesize the graphene oxide nanoribbons. The SEM and TEM studies were carried out on untreated a...
