Inorganic sulphate and silicate is required by all mammalian cells to function properly, it the most abundant anion in human plasma. Sulphate ions are major source of sulphur which considered an important element for sustenance life as present essential amino properly.This paper aimed compare constitutional physical property pure hydroxyapatite (HA) doped with different kinds anions such (SO42-...
the present study was an attempt to determine the types of motivation and levels of foreign language learning anxiety among efl students studying at azad and state universities in kermanshah and to determine the relationship between these two factors and language proficiency and gender. to this end, the foreign language learning motivation scale, by deci and ryan )1985(, were administered to 12...
the current thesis is composed in five chapters in the following fashion: chapter two encompasses the applied framework of the project in details; the methodology of carl gustav jung to explain the process of individuation, the major archetypes and their attributes and his techniques to assess the mind’s strata are all explained. moreover, the austrian psychoanalysts, heinz kohut’s models of a...
In many plants, efflux of organic anions from roots has been proposed as one of the major Al resistance mechanisms. However it remains unknown how plants regulate efflux of organic anions in response to Al. In this study, the regulatory mechanisms of Al-responsive malate efflux in wheat (Triticum aestivum) were characterized focusing on the role of protein phosphorylation. Al-resistant wheat (c...
Selenium (Se) is a problematic contaminant for many regions worldwide. Adsorption is by far the most researched and most promising method in treating Se laden waters. The major limitations in using those adsorbents are the preferential adsorption for either selenite (SeO3) or selenate (SeO4) and interferences by anions such as phosphates. The objective of this study was to remove Se from aqueou...
Calculations are presented for the glycine–(H2O)3 cluster anion, with glycine in canonical or zwitterionic form. The zwitterionic anions are predicted to be considerably lower in energy than the canonical anions, and the latter forms are found to be prone to isomerization to the zwitterionic anions. Therefore, we predict that the zwitterionic anions would be observed predominantly in the gas ph...
Inorganic anions were separated on a reversed-phase stationary phase dynamically modified with crown ether as a selector in capillary ion chromatography. The eluent contained crown ether, acetonitrile and a salt. Free and cation-trapped crown ether molecules in the eluent were adsorbed on a hydrophobic stationary phase such as triacontyl-functionalized silica (C30). The eluent cations trappe...
