Oximes were oxidized to the corresponding carbonyl compounds in good to high yields by ecofriendlyand green oxidant, H202 catalyzed by Montmorillonite K-10 supported Mangenese(II)Chloride. The structures of these compounds were favorably compared with the results of ab initiocalculations at three temperatures. Computational methods allow for the visualization of largeamounts of structural data ...

green architecture, or green design, is an approach to building that minimizes harmful effects on human health and the environment. the “green” architect or designer attempts to safeguard air, water, and earth by choosing eco-friendly building materials and construction practices. so, green architecture is building and structure design philosophy that aims at minimal use of non-renewable and/or...
Neat chlorosulfonic acid reacts with anhydrous sodium tungstate to give tungstate sulfuric acid (TSA), a new dibasic inorganic solid acid in which two sulfuric acid molecules connect to a tungstate moiety via a covalent bond. A variety of oximes were oxidized to their parent carbonyl compounds under mild conditions with excellent yields in short times by a heterogeneous wet TSA/KMnO4 in dichlor...
نفوذپذیری و رواناب بهعنوان مهمترین فرآیندها و پدیدههای فیزیکی در یک حوضهآبخیز میباشند که ارزیابی برخی از خصوصیات و پارامترهای آنها از اهمیت خاصی برخوردار است. با توجه به اینکه در حوضههایآبخیز تخمین تمامی پارامترهای موردنیاز جهت بررسی میزان نفوذپذیری و رواناب میسر نمیباشد لذا انتخاب مدلی که بتواند پیشبینی با دقت قابلقبولی را ارائه کند، امری ضروری بهنظر میرسد. تحقیق حاضر با هدف مقای...
background & aim: in this study, is done during one-year research on blue–green and green algae for antimicrobial activity in mashhad suburb. aqueous, ether, and methanol extracts from 44 species blue – green algae and green algae were examined for antimicrobial properties against four bacteria (tow positive gram bacteria and tow negative gram bacteria) and tow fungous. material & meth...
nowadays, paying attention to the environmental needs and desires of consumersand trying to satisfy them by designing marketing activities in an environmentallyfriendly way, is the best way to increase their satisfaction and finally, gaincompetitive advantage. prior research has paid much attention to the consumerbehavior and marketing activities of corporate organizations, but none has studied...
this paper classifies green envelopes as green roofs and green walls according to effective factors, which were derived from literature to compare the green envelopes’ thermal and energy performance in a more effective way. for this purpose, an extensive literature review was carried out by searching keywords in databases and studying related journal papers and articles. the research method for...
