Potassium (K) fixation by phyllosilicates clay minerals is a very important process influencing the availability of K for plants. Information about K fixation is limited in Hamadan soils. The objectives of this research were to determine potassium fixation capacity (PFC) and potassium fixation index (PFI) of 10 surface soils of Hamadan province and the correlation of these parameters with soil ...
Small GTPases of the Rho family (Rho, Rac, and Cdc42) are key regulatory molecules in phagocyte function. Members of the group are involved at multiple and varied steps in the migratory, secretory, and killing processes elicited in polymorphonuclear and mononuclear leukocytes upon encountering pathogenic microorganisms in the course of the innate and acquired immune response [1]. Rho GTPases ar...
In the present work, the structural and electronic properties, and conductivity of (5,5) and (6,6) Single Walled Carbon Nanotubes in the ground state have done by using the Hartree-Fock and density functional theory DFT-B3LYP/6-31G* level. Delocalization of charge density between the bonding or lone pair and antibonding orbitals calculated by NBO (natural bond orbital) analysis. These methods a...
We have examined the adsorption behaviors of carbon monoxide (CO) molecule on TiO2 anatase supported Au overlayers. The results of density functional theory (DFT) calculations were used in order to gain insights into the effects of the adsorption of CO molecules on the considered hybrid nanostructures. We have investigated different adsorption geometries of CO over the nanoparticles....
Clinical experience of 50 patients with the CHARGE association is reviewed and problems with management of children born with multiple system involvement is highlighted. It was found that the outlook for survival was poor if more than one of the following three features was present: cyanotic cardiac lesions, bilateral posterior choanal atresia, or tracheo-oesophageal fistula. Mortality was larg...
Computer simulation of charge transport in GaAs resistive-gate charge-coupled devices is reported. The simulation has been performed for 10 /1-m finger spacings, doping concentrations in the range of I X 10_1 X 10 cm -3, effective channel thicknesses 0.1-1.0 ,urn, lateral applied fields 3-10 kV/cm, and charge packet sizes 5%-100% offull bucket capacity. Inhibition of charge packet broadening du...
Charge and spin-orderings in the 1 4 -filled organic CT solids are of strong interest, especially in view of their possible relations to organic superconductivity. We show that the charge order (CO) in both 1D and 2D CT solids is of the ...1100... type, in contradiction to mean field prediction of ...1010... CO. We present detailed computations for metal-insulator and magnetic insulator-insulat...
the law of embryo donatioin declares that legitimacy of the process of in vitro fertilization is dependent upon observation of religious precepts, without specifying those precepts. as it is doctors of medicine who are in charge of that process, the lawmakers should reconsider that law and, while announcing a method which is religiously lawful, determine religious criteria of the process. as so...
In this note I examine some implications of stochastic interpretations of quantum mechanics for the concept of "charge without charge" presented by Wheeler and Misner. I argue that if a stochastic interpretation of quantum mechanics were correct, then certain shortcomings of the "charge without charge" concept could be overcome.
The transfer of charge at the molecular level plays a fundamental role in many areas of chemistry, physics, biology and materials science. Today, more than 60 years after the seminal work of R. A. Marcus, charge transfer is still a very active field of research. An important recent impetus comes from the ability to resolve ever faster temporal events, down to the attosecond time scale. Such a h...
