introduction compartmental analysis allows the mathematical separation of tissues and organs to determine activity concentration in each point of interest. biodistribution studies on humans are costly and complicated, whereas such assessments can be easily performed on rodents. in this study, we aimed to develop a pharmacokinetic model of 153sm-maltolate complex as a novel therapeutic agent and...

In this article we establish the uniqueness of solutions to first-order matrix dynamic equations on time scales. These results extend the results presented in [16], to more complex systems of n × n matrices. Following the ideas in [5, Chap 5], we identify Lipschitz conditions that are suitable for generalizing n× n models on time scales.

The growing importance of economic and environmental issues associated with the replacement of transportation infrastructure creates a demand for new techniques that are able to predict accurately the behaviour of existing structures. While monitoring structural behaviour can help reduce uncertainties, measured data alone is not sufficient to determine the behaviour of a structure. Models are n...

in this project, 4,4?-methylenebis(3-chloro-2,6-diethyl trimellitimidobenzene) as a diacid, was prepared by the reaction of trimellitic anhydride (tma) with 4,4?-methylenebis(3-chloro-2,6-diethylaniline) (mcdea). the novel poly(amide-imide) (pai) was synthesized from the reaction of 4,4?-methylenebis(3-chloro-2,6-diethyl trimellitimidobenzene) as a diacid with mcdea under green condition using ...

تعریف مساله،اهداف و سوالات تحقیق: در زبان محاوره ایی، شکل یک شی را با اشیایی که از قبل در ذهن دارند می شناسند. به عنوان مثال اکثر مردم نقشه ایتالیا را شبیه چکمه و نقشه ایران را شکلی شبیه به گربه می دانند. در واقع تعریف شکل به این گونه، مفهومی کیفی را دنبال می کند. اما اگر یک محقق آماری علاقه مند به ارزیابی کمی اشکال براساس ساختار هندسی آنها باشد نیازمند تعریفی مناسبتر می باشد که به نوعی مفاهیم...
