selection of favorite cultivars and lines affected with genotype- environment interaction dramatically. in order to study of genotype × environment interaction in rice, 12 lines with 2 commercial cultivars as check (neda and fajr) was studied in 9 different environments (3 location and 3 years). the experiment was randomized complete block design (rcbd) with three replications. the differences ...

This paper presents research proposals on the interdisciplinary research infrastructure for understanding human reasoning in game-theoretic terms. Strategic reasoning impacts human decision making in social, economical and competitive interactions. The provided introduction summarizes concepts from AI, game theory and psychology. First result is a concept of interdisciplinary game description l...

A simple configuration is first proposed for the pores used by sodium and potassium ions in moving through the neural membrane. The voltage dependence of the ion current through a system of such pores is then derived from diffusion theory and shown not to agree well with experimental observation. Good agreement is obtained, however, when the end segments of the pores are modified to include con...

The interaction of Fe2+ ion with Pyrazole was theoretically studied by Gussian 03, software at HF/(LanL2DZ+6-31G) and HF/ (LanL2DZ+6-31G (d)) levels in gas phase and solution. In this study acompartion between optimized structures of Pyrazole molecule in aspect of thermodynamicparameters such as enthalpy (H°), Gibbs free energy (G°) and entropy (S°) in presence of metallic ion(Fe2+), was perfor...

The plant hormone abscisic acid (ABA) serves as a physiological monitor to assess the water status of plants and, under drought conditions, induces stomatal pore closure by activating specific ion channels, such as a slow-anion channel (SLAC1) that, in turn, mediate ion efflux from the guard cells. Earlier genetic analyses uncovered a protein kinase (OST1) and several 2C-type phosphatases, as r...

چکیده با کاهش ابعاد ترانزیستورهای ماسفت و نزدیک شدن به حد نانومتری، شیب زیر آستانه ترانزیستورها زیاد می¬شود. بالا بودن شیب زیر آستانه در این ترانزیستورها و داشتن نسبت ion/ioff پایین، کاربرد آنها را در مدارهای دیجیتال و آنالوگ دچار چالش می¬کند. برای کاهش شیب زیر آستانه و همچنین افزایش نسبت ion/ioff، ساختارهای تازه ای معرفی شده است که ترانزیستورهای اثر میدانی تونل زنی یکی از آنها است. این تران...
