Uranium Extraction from Solid Waste as Nitrate Complex with D2EHPA, TOPO and their Synergistic Mixture

synthesis and characterization of some macrocyclic schiff bases

ماکروسیکلهای شیف باز از اهمیت زیادی در شیمی آلی و دارویی برخوردار می باشند. این ماکروسیکلها با دارابودن گروه های مناسب در مکانهای مناسب می توانند فلزاتی مثل مس، نیکل و ... را در حفره های خود به دام انداخته، کمپلکسهای پایدار تولید نمایند. در این پایان نامه ابتدا یک دی آلدئید آروماتیک از گلیسیرین تهیه می شود و در مرحله بعدی واکنش با دی آمینهای آروماتیک و یا آلیفاتیک در رقتهای بسیار زیاد منجر به ت...

Ontology Extraction for Educational Knowledge Bases

A student who wishes to learn about some particular topic does not have many options. An often used tool is the search engine, which gives a tiny and difficult to control window into the vast amounts of information that is available on the Internet. A student who wants to learn some concept should be able to interact with the available information in a coherent and personalized way. The classro...

Some factors affecting the extraction of nitrogenous materials from leaves of various species.

On the basis of experiments with tobacco, Crook (1946) has worked out a technique for the extraction of nitrogenous materials from leaves. Its usefulness has now been tested on leaves from other plants, although no attempt has been made to apply the technique to a comprehensive selection of plants. Those used had been brought to the laboratory for other studies or were conveniently available fr...

Synergistic Activity of Green Silver Nanoparticles with Antibiotics

ObjectiveThe present work represents the green synthesis of silver nanoparticles using Withania coagulans extract and its antibacterial property. The synergy, additive, bacteriostatic and bactericidal effect of silver nanoparticles was determined against Enterococcus faecalis, Staphylococcus aureus, Escherichia coli, Proteus vulgaris, Salmonella typhi, and Vibrio cholerae. Methods <...
