In many industrialized areas, the highest concentration of particulate matter, as a major concern on public health, is being felt worldwide problem. Since the air pollution assessment and its evaluation with considering spatial dispersion analysis because of various factors are complex, in this paper, GIS-based modeling approach was utilized to zoning PM2.5 dispersion over Tehran, du...

Block copolymer nano-micelles are especially important in cancer treatment because of their fine dimensions. In this article, three systems of amphiphilic copolymers with similar lengths and different ratios of the hydrophobic and hydrophilic chains are studied using implicit-solvent coarse-grained molecular dynamics simulations. The factor fphil is defined as the ratio of the number...

25 Objective: We compared the flow rates, reactivity and morphology of the distal Internal Thoracic Artery 26 (ITA) and its branches, the Superior Epigastric (SE) and Musculophrenic (MP) arteries to test their 27 applicability as possible conduits in coronary artery bypass grafting (CABG) surgeries. 28 Methods: Skeletonized ITA and sub-divisions of patients undergoing CABG were studied 29 intra...

In contrast to the corundum-type A2X3 structure, which has only one crystallographic site available for trivalent cations (e.g., in hematite), closely related ABX3 ilmenite-type structure comprises two different octahedrally coordinated positions that are usually filled with differently charged ions Fe2+Ti4+O3 ilmenite). Here, we report a synthesis of first binary compound fabricated from simpl...

The budding yeast Saccharomyces cerevisiae is a model organism that is commonly used to investigate control of the eukaryotic cell cycle. Moreover, because of the extensive experimental data on wild type and mutant phenotypes, it is also particularly suitable for mathematical modelling and analysis. Here, I present a new Boolean model of the budding yeast cell cycle. This model is consistent wi...
