Abstract This study characterizes the electronic, optical, elastic, and thermal properties of bulk and nanometric Si and ZrO2 materials through first-principles and theoretical calculations. The first part of this study presents an investigation of the physical properties, such as electronic and optical, of bulk Si and nanocrystals by using the first-principles method through pseudopotential density […]

Summary           Hyperthyroidism is a thyroid disease most common among women’s, in which thyroid gland is over activated and produce too much thyroid hormone. The present study was designed to investigate the effect of hyperthyroidism on endothelin-1 (ET-1) level, hemodynamic parameters and relationship between them.
