a simple, rapid and low-cost scanner spectroscopy method for the glucose determination by utilizing glucose oxidase and cdte/tga quantum dots as chromoionophore has been described. the detection was based on the combination of the glucose enzymatic reaction and the quenching effect of h2o2 on the cdte quantum dots (qds) photoluminescence.in this study glucose was determined by utilizing glucose...
The reaction indices of π-electronic structures of the diuretics, xanthine, thiazide and triazine derivatives were calculated. An attempt was made to explain the potency of the diuretic action in the light of quantum chemistry. The reaction indices of xanthine derivatives, the first frontier superdelocalizability at the substi tuent occupying the 7-position of the highest occupied orbital an...
Desertification refers to land degradation phenomenon in arid, semi-arid and dry sub-humid areas, resulting from various factors including climate variation and human activities. For evaluation and mapping of desertification many research have been conducted leading to regional and local models. In this research, among different existing methods IMDPA was selected and desertification intensity...

Therefore, the purpose of this study was to compare two types of specific and comprehensive balance exercises at ...
Background: This study evaluated the effects of 1:1 mixture of aqueous root bark extracts of Anogeissus leiocarpus (DC) Guill & Perr (Combretaceae) and Terminalia avicennioides Guill & Perr (Combretaceae) in male rats. Methods: Male rats were orally administered a 1:1 mixture of both extracts (250, 500 and 1000 mg/kg body weight) for seven days. Liver and kidney function indices, haematologica...
political participation can be considered as one of the indices in social and political development in different countries. women, who are commonly included in a society, can have essential roles to control a community and its political, social and cultural developments as well. therefore investigating women's political behavior is especially important to political and dynamical stabilitie...
Background and Objectives: The aim of the present study was to assess the probable heavy metals contamination in topsoil surrounding Venarj mine in Qom province using contamination indices and artificial neural networks method. Material and methods: in order to evaluate the contamination status around Venarj mine in Qom province, 70 soil samples were collected in an area of 22 Km2, and the to...
Morphotectonic investigations were carried out by the use of morphometric indices which serve as a tool of identification in regions with active tectonic warp. Landforms in active deformation area are produced from relations of tectonic and surficial processes. One of the most significant landforms underground is rivers that are extremely responsive to tectonic movements mainly uplift and tilti...
