this study was conducted in assaluyeh region, southwest of iran to show utilization and efficiency of sequential extraction analysis in environmental impact studies using soil and related regolith materials as sample media. in order to investigate distribution of heavy metals, optimized bcr (community bureau of reference) sequential extraction analysis method was used. in this caseeight represe...

lack of intimacy and emotional disconnection became a main challenge in contemporary family that can be interpreted and perceived differently from variant viewpoints. the current study aimed to explore the context and women’s way of dealing by emotional separation through investigation of perception and subjective meaning of women involved in this process. research was done in qualitative appro...

spermatogonial stem cell (ssc) technologies provide multiple opportunities for research in the field of biotechnology and regenerative medicine. the therapeutic use of embryonic stem cells (escs) is restricted due to severe ethical and immunological concerns. therefore, we need a new pluripotent cell type. despite well-known role of germ cells in the gametogenesis, some facts apparently show th...

Media can be a good representation of dominant ideologies in society. The analysis of such discourse can shed light on the mental and social structures of people in society. Adopting van Dijk’s (1995) layout of discourse ideology and his (2000) practical and general outline of ideological analysis, this study analyzes the Iranian movie A Separation, the winner of the 84th An...

background: today, through various industrial processes, toxic heavy metals are released into aquatic environments that are harmful to the ecosystem. in the present investigation, removal of such contaminants from industrial wastewater is necessary. the purpose was made to extend an ecofriendly technology by using a bio carbon generated from sunflower waste biomass. methods: the impact of initi...

In this article, we show – using a reasoning applicable to both the excitation spectrum in the chiral bag model and the hyperfine structure of diatomic molecules – that the generic form of a nonabelian Berry potential appears in heavy quark effective theory (HQET) and that the Berry potential vanishes for the solitonheavy meson bound state in the heavy-quark limit. The vanishing of the Berry po...

A mild acid hydrolysis process is developed for upgrading of the anhydrosugars bio-oil heavy ends into bio-ethanol with high compatibility downstream separation and fermentation sugars in a pyrolysis based biorefinery.

A method for the separation of folinic acid diastereomers by capillary electrophoresis in chiral separation media was developed. Aiming to achieve a good separation of the anionic analytes, a newly synthesized cationic β-cyclodextrin derivative, mono-6-deoxy-6-piperdine-β-cyclodextrin, was applied as the chiral selector. The effect of background electrolyte pH, the concentration of the cyclodex...

The present feature describes for the first time the application of spores from Aspergillus sp. IMPMS7 to break out crude oil-in-water emulsions (O/W). The fungal spores were isolated from marine sediments polluted with petroleum hydrocarbons. The spores exhibited the ability to destabilize different O/W emulsions prepared with medium, heavy or extra-heavy Mexican crude oils with specific gravi...
