in this thesis, structural, electronical, and optical properties of inverse pervskite(ca3pbo) in cubic phase have been investigated.the calculation have been done based on density functional theory and according to generalized gradiant approximate (gga) as correlating potential. in order to calculate the configurations, implementing in the wien2k code have been used from 2013 version. first of ...
this study describes a new simple, sensitive and selective catalytic kinetic spectrophotometricmethod for the determination of vanadium (v). the method is based upon the catalytic effect ofvanadium (v) on the oxidation of carminic acid by bromate in sulfuric acid media. the reaction wasfollowed spectrophotometrically by measuring the decrease in absorbance at 490 nm and thedependence of sensiti...
the debate whether esp teachers need to have knowledge of the specialized field they are teaching has been an issue in the literature over the last two decades. the aim of conducting this study was to explore iranian learners’ and instructors’ beliefs and attitudes concerning the role of specialized knowledge in teaching esp classes. a seventeen item questionnaire was administered to 400 esp le...
flow in natural river bends is a complex and turbulent phenomenon which affects the scour and sedimentations and causes an irregular bed topography on the bed. for the reason, the flow hydralics and the parameters which affect the flow to be studied and understand. in this study the effect of bed and wall roughness using the software fluent discussed in a sharp 90-degree flume bend with 40.3cm ...
The purpose of the study was to investigate the prevalence of β-haemolytic Aeromonas hydrophila strains in 83 samples from cooled horse mackerel, rainbow trout, Black sea roach, silver carp, vacuum-packed rainbow trout fillets and 20 samples frozen rainbow trout and to establish the minimum inhibitory concentrations (MIC) of several antimicrobial drugs against these strains. Forty-five Aeromona...
A molecular imprinted polymer (MIP) was computationally designed and synthesized for the selective extraction of metaproterenol (MTP), from human plasma. In this regards semi empirical MP3 and mechanical quantum (DFT) calculations were used to find a suitable functional monomers. On the basis of computational and experimental results, acrylic acid (AA) and DMSO:MeOH (90:10 %V/V) were found to b...
abstract foreign and iranian cultures are far distinct in the constraints imposed on writing and translating for children, since the iranian literary system is mainly concerned with cultural and religious instructions which lead to manipulation of translated texts. this study sought to identify the cultural and social constraints and norms which determined the strategies applied in the transl...
With the increase of neglected diseases such as leishmaniasis and Chagas disease, there wasa need for the search for new therapeutic alternatives that reduce the harm caused by medicineavailable for treatment. Thus, this study was performed to investigate the antiparasitic activityof the essential oil from the fruits of Piper tuberculatum Jacq, against lines of Leishmaniabraziliensis (MHOM/CO/8...
The current work highlights the antioxidant, cytotoxicity and antimicrobial activities of methanol extract Caralluma russeliana their alkaloids phenolics composition by HPLC analysis. antioxidant activity C. displayed that it quenched DPPH with IC50 119.17 μg/ml, ABTS 155.71 NO 223.40 μg/ml H2O2 184.40 μg/ml. Among tested cell lines, hepatocellular (HepG2) lung (A549) were most sensitive lines ...
with the increasing population and the need for more food, as well as with the development of science and technology, human approach to unnatural and often chemical inputs to increase agricultural production has been a great expansion and problems such as increased cancers, chronic diseases has created environmental pollution. implementation of organic organic is a solution to these problems . ...
