Drought is a major environmental disaster in many parts of the world. Knowledge about the timing, severity and extentof drought can aid planning and decision-making. Drought indices derived from in-situ meteorological data have coarsespatial and temporal resolutions, thus, obtaining a real-time drought condition over a large area is difficult. This studyused advanced very high resolution radiom...
climate changes due to global warming is affecting world agriculture adversely. heat stress due to global warming has turned to one of the most important factors reducing quantity and quality of plants production such as tomato. despite of wide cultivation of tomato and high temperature effects on its production, unfortunately; research in this area is scarce. this study was conducted to invest...
Background: Dentin dysplasia (DD) is a rare disturbance of dentin formation, characterized by normal enamel but atypical dentin formation with abnormal pulpal morphology. In DD type I, the teeth appear clinically normal in morphologic appearance and color. Radiographic analysis shows obliteration of all pulp chambers as well as short, blunted, and malformed or absent roots with multiple periapi...
Here D ⊂ R is a bounded domain with Lipschitz boundary ΓD, E is the electric field, H is the magnetic field, x̂ = x/|x|, and n is the unit outer normal to ΓD. The applied current J and the initial conditions E0,H0 are assumed to be supported in the circle BR = {x ∈ R : |x| < R} for some R > 0. The electric permittivity ε and magnetic permeability μ are assumed to be positive constants. We remark...
in recent years, there has been a growing interest among researchers to investigate the relationship betweenteacher self-efficacy and classroom behavior management, especially students misbehavior. therefore, this study aimed to comparatively investigate english and arabic teachers’ use of different behavior managementstrategies, their self-efficacy, and their success in an iranian context. th...
In order to evaluate the effect of biofertilizers (Rhizobium and mycorrhiza) on yield and qualitative characteristics of Pinto bean under deficit irrigation, an experiment was conducted as split plot based on a randomized complete block design with three replications in 2017. Experimental treatments included irrigation regime with two levels (normal and deficit irrigation) as main plots and bio...
In this paper, we investigate contact CR submanifolds of contact CR dimension in Sasakian space form and introduce the general structure of these submanifolds and then studying structures of this submanifols with the condition h(FX,Y)+h(X,FY)=g(FX,Y)zeta, for the normal vector field zeta, which is nonzero, and we classify these submanifolds.
investigation of inheritance, mode of gene action and determination of effective breeding strategy for improvement of physiological and morpho-physiological traits specifically in drought stress conditions is very important. to determine the inheritance pattern and genetic parameters of quantitative characters in bread wheat (triticum aestivum), p1, p2, bc1, bc2, f1, f2 generations derived from...
We introduce a new level set method for motion in normal direction. It is based on a formulation in the form of a second order forward-backward diffusion equation. The equation is discretized by the finite volume method. We propose a semi-implicit time discretization taking into account the forward diffusion part of the solution in an implicit way, while the backward diffusion part is treated e...
Heterogeneous photocatalytic degradation of Polynuclear Aromatic Hydrocarbons (PAHs) contaminated soil in the Pars Economic and Energy Zone was carried out <span style="font-size: 10pt; color: #000000;...
