This paper aims to calculate the thermal spreading resistance for a hyperellipse on a half space, with uniform heat flux. The effect of shape and aspect ratio on a steady state averaged temperature and the centroid temperature based thermal spreading resistance is studied. The square root of source area and characteristic dimension are assumed as characteristic length scales to obtain the resul...

DC-DC converters, common in battery-driven, portable, and other high-efficiency systems, can deliver efficiencies greater than 95% while boosting, reducing, or inverting supply voltages. Resistance in the power source is one of the most important factors that can limit efficiency. This application note describes the effects of source resistance, how to calculate efficiency, real-world considera...

production and approval of trastuzumab (herceptin®) for the treatment of metastatic breast cancer (mbc) was a millstone in antibody-based targeted therapy in the cancer treatment. however, despite the early success in the clinical trials, trastuzumab failed to appreciate the initial attraction due to development of resistance to the drug. the majority of patients who benefit from the drug acqui...

background : anopheles stephensi is a sub-tropical species and has been considered as one of the most important vector of human malaria throughout the middle east and south asian region including the malarious areas of southern iran. current reports confirmed an. stephensi resistance to temephos in oman and india. however, there is no comprehensive research on mechanisms of temephos resistance ...

the major histocompatibility complex (mhc) plays a central role in the control of disease resistance and immune response. extensive genetic diversity in mhc genes provides a valuable source for genetic improvement, via selection, in many domestic animals. exon 2 of the class ii mhc, termed ovar-drb1 in domestic sheep (ovis aries), has been suggested as important disease resistance and immune re...

nowadays, many antibiotics are being used to control infectious diseases. inappropriate use of antibiotics leads to emergence of resistant bacteria and problems such as a prolonged course of treatment. medicinal plants and their derivatives, as a good source of treatment, are effective against drug resistance. in this study we have evaluated the antimicrobial activity of herbal essential oils o...
