The solubilization of polycyclic aromatic hydrocarbons by purines.
In all but two cases agreement between the results by the two methods was highly satisfactory, having regard to the nature of the materiaf analyzed. Moreover, such diiferences as existed were not all in one direction, so that there is no indication that one method offers a more efficient method of fat extraction than the other. The two specimens which showed less satisfactory agreement were ver...
متن کاملInvestigating the Presence of Polycyclic Aromatic Hydrocarbons in Doogh
Background and purpose: Polycyclic aromatic hydrocarbons (PAHs) are one of the most common environmental pollutants that are proven to be carcinogenic and mutagenic. Doogh, is a widely consumed fermented yoghurt drink in Iran. The aim of this study was to determine the presence and concentration of PAHs in different brands of Doogh in Tehran, Iran. Materials and methods: In this study, we synt...

این مطالعه به دو روش کمی و کیفی و با هدف بررسی استراتژی های فراشناختی فراگیران زبان انگلیسی به عنوان زبان خارجی در دو آزمون نوشتن و نوشتن ترکیبی انجام پذیرفت. در بخش کمی برای سنجش میزان استراتژی های فراشناختی از یک پرسشنامه که بر اساس مدل بکمن و پالمر (1996) ساخته شده بود استفاده شد. پایایی و روایی سازه ی پرسشنامه هنگام مطالعه ی پایلوت و روایی محتوای آن با جمع آوری نظرات نُه متخصص در رشته سنجیده...
Biodegradation of Polycyclic Aromatic Hydrocarbons (PAHs) in Petroleum Contaminated Soils
Polycyclic aromatic hydrocarbons are a class of potentially hazardous chemicals of environmental and health concern. PAHs are one of the most prevalent groups of contaminants found in soil. Biodegradation of complex hydrocarbon usually requires the cooperation of more than single specie. In this research biotreatment of PAH (phenanthrene) was studied in a solid-phase reactor using indigenou...
متن کاملPolycyclic antiaromatic hydrocarbons.
Magnetically induced current densities have been calculated for a series of hydrocarbons consisting of hexadehydro[12]annulene rings alternatingly fused with benzenes. The calculations show that all molecular rings of the studied molecules sustain paramagnetic ring currents. The new class of molecules is therefore coined polycyclic antiaromatic hydrocarbons (PAAH).
