Frontispiece: Drug Syntheses Beyond the Rule of 5

survey on the rule of the due & hindering relying on the sheikh ansaris ideas

قاعده مقتضی و مانع در متون فقهی کم و بیش مستند احکام قرار گرفته و مورد مناقشه فقهاء و اصولیین می باشد و مشهور معتقند مقتضی و مانع، قاعده نیست بلکه یکی از مسائل ذیل استصحاب است لذا نگارنده بر آن شد تا پیرامون این قاعده پژوهش جامعی انجام دهد. به عقیده ما مقتضی دارای حیثیت مستقلی است و هر گاه می گوییم مقتضی احراز شد یعنی با ماهیت مستقل خودش محرز گشته و قطعا اقتضاء خود را خواهد داشت مانند نکاح که ...

The Phase Rule: Beyond Myopia to Understanding

The Gibbs phase rule relating the number of degrees of freedom f of a system to the number of components c and the number of coexisting phases p is a central, universally used relation, expressed by what is probably the simplest formula in the natural sciences, f 1⁄4 c p + 2. Research into the behavior of small systems, notably atomic clusters, has shown in recent years that the phase rule is n...

The Effect of Silica Coating on the Drug Release Profile and Biocompatibility of Nano-MOF-5

The purpose of this study was the surface modification of nano MOF-5 (NMOF-5) or IRMOF-1 (Zn4O(C8H4O4)3) in order to prevent its rapid degradation in the phosphate-buffered saline (PBS), along with the simultaneous increase in its biocompatibility. The NMOF-5 sample was synthesized under the ultrasound irradiation and then it was loaded wit...

The Theory of Neural Network.s: the Hebb Rule and Beyond

Recent studies of the statistical mechanics of neural network models of associative memory are reviewed. The paper discusses models which have an energy function but depart from the simple Hebb rule. This includes networks with static synaptic noise, dilute networks and synapses that are nonlinear functions of the Hebb ru1e (e.g., clipped networks). The properties of networks that ernp loy the ...
