attempts have been made to study the thermodynamic behavior of 1,3 butadiene purification columns with the aim of retrofitting those columns to more energy efficient separation schemes. 1,3 butadiene is purified in two columns in series through being separated from methyl acetylene and 1,2 butadiene in the first and second column respectively. comparisons have been made among different therm...
this study predicts corporate bankruptcy five years before its occurrence using financial ratios introduced in altman’s z-score model and current ratio. three estimation methods namely; liner probability, logit and probit models have chosen for model estimation. the sample contains 134 companies in tehran stock exchange during 2003. the precision of prediction of the estimated models for the ma...
Abstract JUNO is a multi-purpose neutrino observatory under construction in the south of China. This publication presents new sensitivity estimates for measurement , m^2_{21} \sin^2 \theta_{12} and \theta_{13} oscillation parameters using reactor antineutrinos, which one primary physics goals experiment. The sensitivities are obtained best knowledge available to da...
in civil engineering concrete is a material combined of hydraulic cement, sand, gravel and water. gravel and sand compose 60 to 70 percent of concrete. these aggregates support compression force of concrete. cement paste acts as glue to stick grain together. in bushehr factories producing aggregates do not operate according to astm standards, so that fineness modulus (fm) of the produced sands ...
cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...
Measuring the neutrino mixing parameter \ensuremath{\sin^2\theta_{13}} to sub-percent precision level could be necessary in next ten years for unitary test of PMNS matrix. In this work, we discuss possibility such a measurement with reactor antineutrinos. We find that single liquid scintillator detector on reasonable scale achieve goal. propose install $\sim10$\% energy resolution at about 2.0~...
the aim of the current study was to investigate the relationship among efl learners learning style preferences, use of language learning strategies, and autonomy. a total of 148 male and female learners, between the ages of 18 and 30, majoring in english literature and english translation at islamic azad university, central tehran were randomly selected. a package of three questionnaires was ad...
Abstract Background Insecticides are applied on a large scale in the environment to control oak processionary moth ( Thaumetopoea processionea ) for protection of human health. Drift insecticides non-target areas is risk surrounding biodiversity. Since habitats caterpillars usually restricted treetops, sprayers used apply biocidal products must be able transport droplets over longer distances. ...
State-of-the-art precision values are presented for the following serum constituents: aldolase (EC 4.1.2.13), alpha-hydroxybutyrate dehydrogenase (EC 1.1.1.30), cholinesterase (EC 3.1.1.8), cortisol, gamma glutamyl transferase (EC 2.3.2.2), haptoglobin, immunoglobulins, lactic acid, leucine aminopeptidase (EC 3.4.1.1), total lipids, osmolality, protein fractions, T3 uptake, thyroxine and vitami...
in this study, the performance of aquacrop model to predict yield production of winter wheat (roshan and gods varieties), water and solute balance of soil profile was evaluated under water and salinity stresses. field experiments were conducted with three levels of saline irrigation water including: s1, s2 and s3corresponding to 1.4, 4.5 and 9.6 ds/m, respectively, and four levels of irrigation...
