the methods which are used to analyze microstrip antennas, are divited into three categories: empirical methods, semi-empirical methods and full-wave analysis. empirical and semi-empirical methods are generally based on some fundamental simplifying assumptions about quality of surface current distribution and substrate thickness. thses simplificatioms cause low accuracy in field evaluation. ful...
in current work, cds/black carbon nanocomposites were successfully synthesized with the aid of chestnut and cadmium nitrate as the starting reagents. besides, the effects of preparation parameters such as reaction time, and precursor concentration on the morphology of products and removal of heavy metals (hg+2, pb+2) were studied by scanning electron microscopy images and batch adsorption mode....
Background: It has been expected that AS1411 aptamer could work against the cancer cells. Although the general information is available, there is still lack of details for the purpose. Therefore, activity of AS1411 aptamer against the nucleolin (NCL) target of cancer cells has been investigated in current work at the molecular scale. In addition, the same features have been also investigated fo...
