One major problem of the conventional solar cells is low conversion efficiency. In this work, we have proposed a new design including hemisphere texturing on top and metallic plasmonic nanostructure under the silicon layer to enhance the optical absorption inside the photosensitive layer.    The finite-difference time-domain (FDTD) method has been used to investigate the interaction of light wi...

Literature review shows that hepatitis C infection may increase the risk of non-hodgkin lymphoma. Reactivation of hepatitis B infection has been reported in patients with hairy cell leukemia after chemotherapy and/or splenectomy. We present hepatitis B surface (HBs) antigenemia and concurrent hepatitis C virus (HCV) seropositivity in a case of hairy cell leukemia. Key Words: Hairy cell leukemi...

conclusions it can be concluded that due to some bioactive and nutrient factors, mscs secretions could be used for recovery of oa as well as prevention of articular cartilage matrix degeneration, using a high dose of cell secretions. results the results revealed a decrease of proteoglycan content in the superficial and intermediate zones and presence of surface fibrillation. therefore, oa induc...

today, due to qualitative growth and scientific advances, energy, especially electricity is increasingly needed by human society. one of the almost endless and pure energy which have been paid attention over the years is the solar energy. solar cells directly convert solar energy into electrical energy and are one of the main blocks of photovoltaic systems. significant improvement has been made...

abstract land surface hydrological models has importance in the determination of soil moisture and temperature, the rate of evapotranspiration, stream flow by emphasis on the land surface physical and dynamic process descriptions. in this research, vic land surface hydrological model has been used for the land surface temperature and stream flow determination. the vic runoff simulation in each ...
