با توجه به پیشرفت روز افزون کاتالیستهای زیگلر- ناتا و کاربرد وسیع ترکیبات الکترون دهنده داخلی و خارجی بر پلیمریزاسیون کئوردیناســیونی الفینها، نقش تتراهیدروفوران (thf) به عنوان عامل تصحیح کننده و تعدیل کننده بر محیط پلیمریزاسیون، شرایط عملیاتی واکنش ، فعالیت کاتالیست و خواص نهایی پلیمر در پلیمریزاسیون اتیلن در فاز دوغابی (slurry) ، مورد بررسی قرار گرفته است. در این پژوهش ازکاتالیست زیگلر- ناتا ...
metronidazole, a synthetic derivative of the nitroimidazole class is a known antibacterial and antiprotozoal agent. the hypolipidemic effect of metronidazole was not known. the authors noticed it incidentally for the first time. after quazi experimental studies on several cases, it was revealed that 750 mg of metronidazole for 10 days significantly decreased serum cholesterol. this trial was pe...

this paper describes how multi-agent system technology can be used as the underpinning platform for voltage control in power systems. in this study, some facts (flexible ac transmission systems) devices are properly designed to coordinate their decisions and actions in order to provide a coordinated secondary voltage control mechanism based on multi-agent theory. each device here is modeled as ...
two simple, accurate and precise methods for simultaneous estimation of esomeprazole and itopride in bulk drug and tablet dosage form have been described. method-a employs formation and solving of simultaneous equation using 231 and 370 nm as two analytical wavelengths. method -b is absorption ratio method, which uses 308 and 331 nm as two analytical wavelengths.beer’s law was obeyed in the con...
background: streptokinase is a potent activator of plasminogen to plasmin, the enzyme that can solubilize the fibrin network in blood clots. streptokinase is currently used in clinical medicine as a thrombolytic agent. it is naturally secreted by β-hemolytic streptococci. methods: to reach an efficient method of purification, an immunoaffinity chromatography method was developed that could puri...
A singularity-robust trajectory generator is presented that, given a prescribed manipulator path and corresponding kinematic solution, computes a feasible trajectory in the presence of kinematic singularities. The resulting trajectory is close to minimum time, subject to individual bounds on joint velocities and accelerations, and follows the path with precision. The algorithm has complexity O(...
