Sediment extracts of stream sediments, collected from inland areas of Lake Shihwa (LSI) and Masan Bay (MBI), were screened for their abilities to induce aryl hydrocarbon receptor (Ah-R) mediated gene expression in vitro. Cell viability assay was also performed to examine cytotoxic effects on the Ah-R-mediated activities of sediment samples. Over 80% (30 out of 36) of sediment raw extracts (REs)...

Sediment, pore water and water samples from the Hyeongsan River, Korea were analyzed for several classes of halogenated aromatic hydrocarbons (HAHs) and their dioxin-like activities were evaluated using the in vitro H4IIE-luc bioassay. Polychlorinated dibenzo-p-dioxins (PCDDs), dibenzofurans (PCDFs), and biphenyls (PCBs) were detected in sediments from all six sampling locations with mean conce...

اثر افزایش مقادیر کم از خاک رس (کلی) اصلاح شده (کلویزیت b??) و پلی ال بازیافتی روی تخریب گرمایی از پلی یورتان نرم، به وسیله تجزیه حرارتی دینامیک (غیرهم دما) در سه سرعت گرمادهی (0c min-1 ?? و?? ،?/?) در اتمسفر نیتروژن بررسی شده بود. روش های isoconversional (model – free) (شامل روش های فلاین، وال و ازاوا (fwo)، کیسینجر، آکاهیرا و سانوز(kas) و تانگ (tang)) و model – fitting (روش های کوتس و ردفر...

The Gibbs sampler can be used to obtain samples of arbitrary size from the posterior distribution over the parameters of a structural equation model (SEM) given covariance data and a prior distribution over the parameters. Point estimates, standard deviations and interval estimates for the parameters can be computed from these samples. If the prior distribution over the parameters is uninformat...

There is some support for the hypothesis that the factor structure of schizophrenia symptoms is similar to the factor structure of schizotypal symptoms in nonschizophrenia populations. However, no studies to date have examined schizotypal symptoms in patients with personality disorders. In this study, confirmatory factor analyses were conducted to test the relative fit of several models of the ...

a one dimensional dynamic model for a riser reactor in a fluidized bed catalytic cracking unit (fccu) for gasoil feed has been developed in two distinct conditions, one for industrial fccu and another for fccu using various frequencies of microwave energy spaced at the height of the riser reactor (fccu-mw). in addition, in order to increase the accuracy of component and bulk diffusion, instanta...

We have established semiclassical kinetic equations for various spin correlated pumping phenomena incorporating adiabatic spin rotation in wave functions. We employ this technique to study topological pumps and illustrate spin pumping in a few models where various spin configurations or topological motors drive adiabatic pumps. In the Rashba model we find that a topological spin pump is driven ...

The chemical contamination of the Loire estuary by three classes of persistent organic pollutants (POPs): the polychlorinated biphenyls (PCBs), the polybrominated diphenyl ethers (PBDEs) and the perfluorinated and polyfluorinated alkyl substances (PFAS), and three families of organic contaminants, the alkylphenols (APs), the polycyclic aromatic hydrocarbon metabolites (OH-PAHs) and the bispheno...
