Objective: Prediction about the advance of programs for achieving to goal is revealed in hope and failure sense is revealed in hopelessness. Therefore, the aim of this research has been study of psychometric characteristics of children hopelessness scale (Kazdin, Rodgers & Colbus, 1986) in Iranian children. Method: Research statistical sample was composed of 482 female and male students of e...
the purpose of the present study was to investigate the latent pattern underlying reading ability . some 272 male and female participants. english majors at the ba level , participated in the study. two valid tests were used in this study, the reading test developed exclusively for the purpose of this project and academic reading section of ielts. to investigate the possible latent underlying...
the length- length (llrs), length-weight (lwr) relationships and relative condition factor (kn) of 505 specimens of pike, (esox lucius linnaeus, 1798) from anzali wetland, southwest of the caspian sea, were studied from april 2012 through march 2013. the length-length relationships among total length (tl), fork length (fl) and standard length (sl) for pike were found to be highly significant (r...
BACKGROUND The present study was performed to assess the association of prothrombotic risk factors and underlying conditions (infections, vascular trauma, immobilization, malignancies, autoimmune diseases, renal diseases, metabolic disorders, obesity, birth asphyxia, cardiac malformations, and use of prothrombotic drugs) with cerebral venous thrombosis (CVT) in children. METHODS AND RESULTS F...
to demonstrate more visibly the close relation between thecontinuity and integrability, a new proof for the banach-zareckitheorem is presented on the basis of the radon-nikodym theoremwhich emphasizes on measure-type properties of the lebesgueintegral. the banach-zarecki theorem says that a real-valuedfunction $f$ is absolutely continuous on a finite closed intervalif and only if it is continuo...
Solidification and stabilization (S/S) by agents stabilizers is an effective way to treat heavy metal-contaminated sediments. Optimization of curing condition crucial minimize the consumption reagents on base S/S. In this work, synergistic effects cement stabilizer mechanical strength leaching toxicity contaminated sediments were investigated, S/S conditions optimized using response surface met...
To explore the characteristics of overland flow resistance under condition sparse vegetative stem coverage and improve basic theoretical research flow, were systematically investigated four slope gradients (S), seven discharges (Q), six degrees vegetation (Cr). The results show that Manning roughness coefficient (n) changes with ratio water depth to height (h/hv) while Reynolds number (Re), Fro...
Modelling and optimization of digestion efficiency of bauxite in Bayer process: Iran Alumina company
In the present work, we investigated and optimized the digestion efficiency, A/S (Al2O3/SiO2 in red mud), and N/S (Na2O/SiO2 in red mud) of mixed bauxite in Iran Alumina Company using the Bayer process. Digestion experiments were carried out in an induction rotary autoclave on a mix of Jajarm, Yazd, Tash, and Shirin Cheshmeh baux...
