introduction: viral hepatitis is one of the causes of premature death in world peoples, according to who reports, five percentage of people are carrier, lethal from this disease is 1%, therefore about 1-1.5 million people each year die from complications of this disease. this disease varies from an acute to chronic illness. the aim of this study was to determine the level of anti-hbs ag (hepati...

the rapid advancement of nanotechnology enables us to use nanoscale particles. this material in terms of physical, chemical and biological characteristics are unique compared to larger particles. increased cell division, apoptosis, oxidative stress has been associated with toxic effects of nano-silver. the aim of this study was to evaluate histipotological changes and enzyme activity in nanopar...

infection with hepatitis c virus (hcv) is a worldwide problem. among hcv proteins, core antigen (ag), besides its importance for diagnostic application is a prime candidate for component of a vaccine. herein, we report results of studies on production of the hydrophilic domain of core ag (2-122) in native conformation by an arabinose induction system in e.coli and the primary characterization o...

In pressurized nuclear reactors, one of the fuel design principles is centerline temperature limit. Since thermal conductivity UO2 not high, increases rapidly from surface to center. To overcome this limitation, use annular type fuels instead solid improvement efforts. study, effects using in a typical PWR are investigated. At same time, adding nanoparticles (〖Al〗_2 O_3,Cu and TiO_2) coolant wa...

Nanosuspensions are proposed for use in improving the thermal efficiency of different systems; including solar power plants. Because their excellent and unique thermo-optical properties, which basis transfer phenomena, they used as working fluids collectors photothermal energy conversion. However, particle agglomeration nanosuspensions remains one most important challenges faced terms usage. Th...

With the aim of gauging their potential as conducting or superconducting materials, we examine the crystal structures and magnetic properties of the roughly one hundred binary, ternary, and quaternary Ag(II) and Ag(III) fluorides in the solid state reported up to date. The Ag(II) cation appears in these species usually in a distorted octahedral environment, either in an [AgF](+) infinite chain ...
