The experiment was carried out in order to evaluate the effects of trace element immobilizing soil amendments, i.e., chalcedonite, dolomite, halloysite, and diatomite on the chemical characteristics of soil contaminated with Cr and the uptake of metals by plants. The study utilized analysis of variance (ANOVA), principal component analysis (PCA) and Factor Analysis (FA). The content of trace el...
The development of a platinum-free catalyst is one of the challenging issues for the global commercialization of fuel cell systems. Here we describe the design and synthesis of nitrogen-containing calcined polybenzimidazole/carbon nanotube hybrids that act as an oxygen reduction catalyst.
The Anzali Ramsar Convention wetland is located in an ecologically and economically important region in Iran. The wetland is largely surrounded by agriculture, natural forests and rangelands (approximately 36% and 63%, respectively). Urban areas consist of less than 1% of the total area. Urban land use produces the highest rates of nutrient transfer into the lake as TN, TP and BOD5 equal to 24,...
A 2-site immunoradiometric assay (IRMA) was performed on the head and thorax of Anopheles culicifacies s.l. and An. pulcherrimus females, the 2 most common anopheline species in the District of Ghassreghand (Baluchistan, Iran), collected during the 2 peak malaria transmission seasons (May and September-October 1991). Positive IRMA results revealed the 2 species as potential vectors of malaria i...
This study aimed to identify the composition of ceramic mass for manufacture bricks with improved properties based on local loam using diatomite and bentonite clay. For experiments, from Almaty deposit (Kazakhstan) was applied as primary product, used production grades 75 100. Diatomite Zhalpak Utesai deposits highly plastic clay Darbazin were additives. An analysis burned products demonstrated...
