1. introduction isfahan oil refinery (isfahan, iran) is responsible for the production of huge amounts of oil waste. as the released organic compounds are highly toxic, carcinogenic, and mutagenic, they can potentially contaminate the soil and groundwater resources of the adjacent area. this is particularly important in isfahan where arid/semi-arid climate has limited the access to adequate sur...

In this study, a commercial chain extender (Polyad PR 002) in concentrations of 0.5, 1.0, and 1.5% w/w was used as compatibilizer post-consumed PET/PA6 blends (25/75, 50/50 e 75/25) processed laboratory mixer. The degradation rate, phase miscibility, chemical interaction, crystallization, melting behavior, well the thermal stability mixtures, were analyzed by torque rheometry, scanning electron...

recently, application of sa has increased to improve plants resistance to stresses such as drought. hence, to investigate sa effects on morphophysiological characteristics of fennel(foeniculum vulgare mill.) under drought stress, a split plot experiment based on latin square design with three replications was carried out at research farm of shahid bahonar university of kerman in 2012. three lev...

background and objectives: thermal processing is an effective method in preventing microbial spoilage but high heat transfer in a long time process that leads to quality loss and increased energy consumption. also it is important to consider sensitive nature of food products during the thermal processing. due to the nano-fluids' unique thermo–physical properties compared with the conventio...

Bile acids (BAs) regulate glucose and lipid metabolism. In longitudinal and case-control-studies, we investigated the diurnal variation of serum concentrations of the 15 major BAs as well as the biosynthetic precursor 7α-hydroxy-4-cholesten-3-one (C4) and their associations, respectively, with coronary artery disease (CAD), diabetes mellitus type 2 (T2DM), and non-diabetic metabolic syndrome (M...

in order to study concentrations of soil micro and heavy metal elements in some saffron planting regions of birjand province, an experiment was performed as factorial layout based on a completely randomized block design with three replications at year 2013. treatments were three field ages (annual, triennial and quinquennial) and five saffron regions including aryan shahr, hosseinabad, khosef, ...

Citrobacter freundii bacteria were grown in LB medium containing cadmium ion. In order to reduce adverse effect caused by cadmium, different concentrations of vitamin C, added the growth medium. While concentration was determined spectrophotometer, amounts water and fat-soluble vitamins also HPLC. The varied from 0 (control), 10, 20, 40, 60, 75, 100, 125 ppm has not been observed on bacteria, u...
