Ahmad Ramazani S.A., Ali Dashti

A new model based on a combination of the polymeric multigrain and multilayer models has been developed to predict the polymerization rate, particle growth, morphology, effective parameters on broadening of the molecular weight distribution, number and weight average of the molecular weight, isotacticity index and bulk density of polymer. Mathematical correlations and the kinetics used in t...

We report a first-principles study of electrical transport in a single molecular conductor consisting of a buthane-dithiol sandwiched between two Au (100) electrodes. We show that the current was increased by increasing of the external voltage biases. The projected density of states (PDOS) and transmission coefficients (T(E)) under various external voltage biases are analyzed, and it suggests t...

Background: Melon (Cucumis melo) allergy is one of the most common food allergies, characterized by oral allergy syndrome. To date, two allergen molecules, Cuc m 1 and Cuc m 2, have been fully characterized in melon pulp, but there are few reports about the molecular characteristics of Cuc m 3. Methods:The Cuc m 3 cDNA has been characterized by rapid amplification of cDNA ends (RACE), which ...

Background and purpose: Hydrogels are used as carriers to control drug release. Ostrich oil has fatty acids which plays an important role in growth, division, and health of cells and cause wound healing and have anti-inflammatory effects. Materials and methods: In this experimental study, pH sensitive hydrogel was produced by chitosan deviation and open ring Poly-vinyl pyrrolidon (OR-PVP). The...

Understanding the microscopic dispersion and aggregation of nanoparticles at nanoscale media has become an important challenge during the last decades. Nanoscale modeling techniques are the important tools to tackle many of the complex problems faced by engineers and scientists. Making progress in the investigations at nanoscale whether experimentally or computationally has helped understand th...

شفیعی, معصومه,

The development of radioligand - binding studies has greatly advanced our knowledge of the molecular pharmacology of beta - adrenoceptors. Using this technique it became possible for the first time to directly determine the tissue concentration of beta - adrenoceptors, and by this, the responsiveness of tissues to beta - adrenergic stimulation. One major insight into the molecular pharmacology ...

Salinity stresses act as inhibitor factors of plant growth. They can change the physiological characteristics and limit the production of crops. Sodium nitroprusside (SNP) is a stable free radical which use as a signalling molecule in plants and participates in various plant’s physiological, biochemical and molecular processes and also in plant’s responses to environmental stresses. We investig...
