abstract in first part of this project, the use of a new and biguanid-like catalyst supported on silica as a recyclable catalyst provides a new route for the synthesis of a variety of arylalkylidene rhodanine derivatives through knoevenagle reaction in at present of solvent at room temperature. rhodanine derivatives and especially arylalkylidene rhodanines have proven to be attractive compound...

     An experiment was conducted to determine the effects of different levels of feed intake at 70%, 85% and 100% of the voluntary feed intake on digestibility and rumen microbial protein synthesis. For this purpose, six male lambs (42±1.5 kg BW) were used in a replicated Latin square design (replicated in three periods that were 21 days each). A twenty five days period was assigned as adaptati...

aflp یک ابزار قدرتمند برای تشخیص رونوشت هایی با فراوانی کم است و می تواند بعنوان یک روش کارآمد برای جداسازی ژنهایی که بطور متمایز بیان می شوند، بکار رود. بنابراین القا متمایز ژنها در گندم ( رقم چمران و مرودشت) در پاسخ به قارچ m.graminicola بوسیله آنالیز cdna-aflp مورد مطالعه قرار گرفت . در ابتدا گیاهان بوسیله بیمارگر مایه زنی شدند. نمونه برداری در 6 نقطه زمانی(0، 12، 24، 48، 72 و 96 ساعت) بعد ا...

Background and Objective: Salubrinal- a protein synthesis inhibitor- plays a crucial role in sleep and neuronal inhibition through the GABA activation. According to these evidences, the aim of the present study was to determine the effect of salubrinal on epileptic seizures induced by pentylenetetrazol (PTZ). Materials and Methods: In this expremental study under stereotaxical surgery,...

heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...
