Cancer as global burden with increasing incidence is a second and among third cause of death in developed and developing economies respectively. Surgery, radiotherapy, chemotherapy, hormonal therapy and immunotherapy are the major management options. Thermal therapy is currently gaining attention as an alternative. Radiofrequency, laser, high intensity focused ultrasound, cryo and microwave abl...

Tungsten oxide (WO3) and tungsten oxide hydrate (WO3.H2O) nanoparticles were synthesized via microwave-assisted solution combustion in comparison with the acidic precipitation method. Oxalic acid was used as a surfactant and forming agent in the acidic precipitation method. In addition to oxalic acid, glycine and citric acid were also used as fuels in the microw...

Assuming the dark matter is made entirely from neutralinos, we re-visit the role of their annihilation on the temperature of diffuse gas in the high redshift universe. We consider neutralinos of particle mass 36 GeV and 100 GeV, respectively. The former is able to produce ∼ 7 ee particles per annihilation through the fremionic channel, and the latter ∼ 53 particles assuming a purely bosonic cha...

Abstract: Microwave processing is one of the novel methods for combustion synthesis of intermetallic compounds andcomposites. This method brings about a lot of opportunities for processing of uniquely characterized materials. In thisstudy, the combustion synthesis of TiAl/Al2O3 composite via microwave heating has been investigated by thedevelopment of a heat transfer model including a microwave...

an investigation on the thermal performance of the soil as geothermal heat energy storage medium has been conducted. the thermal characteristics of the soil storage and the heat transfer from a heat exchanger in the soil, surrounding and bottom surface will be discussed. this investigation forms a contribution to a project to realize such storage to be charged from a solar heating system. this ...

With the rapid development of electronic technologies, anxiety regarding the potential health hazards induced by microwave radiation (MW) has been growing in recent years. The brain is one of the most sensitive target organs for microwave radiation, where mitochondrial injury occurs earlier and more severely than in other organs. Energy metabolism disorders do play an important role during the ...

OBJECTIVE The aim of this study was to evaluate the effect of repeated microwave disinfections on the dimensional stability of acrylic dentures. MATERIALS AND METHODS Three groups of dentures made of a heat polymerized acrylic resin were tested. I: dentures kept in water (control group). II: dentures microwaved daily while being immersed into water (wet disinfection). III: dentures microwaved...

PURPOSE To develop a novel endovascular heating source using a magnetic resonance (MR) imaging guidewire (MRIG) to deliver controlled microwave energy into the target vessel for thermal enhancement of vascular gene transfection. MATERIALS AND METHODS A 0.032-inch MRIG was connected to a 2.45-GHz microwave generator. We 1) calculated the microwave power loss along the MRIG, 2) simulated the po...
