the present investigation was carried out to isolate and characterize antagonistic bacteria against wilt causing fungal pathogen i.e. fusarium oxysporum, from the rhizosphere of tomato. fifty-six bacterial strains were isolated from the rhizosphere soil samples of healthy tomato fields, collected from different locations of faridabad district, haryana, india. out of these, ten isolates were fou...

We present exact results on the behavior of the thermodynamic Casimir force and the excess free energy in the framework of the d -dimensional spherical model with a power law long-ranged interaction decaying at large distances r as r(-d-sigma) , where sigma<d<2sigma and 0<sigma< or =2 . For a film geometry and under periodic boundary conditions we consider the behavior of these quantities near ...

In this article a comparative study for modeling and optimization of 2-methylpropane-2-thiol removal from contaminated soil by ultrasound is investigated. Central Composite Design (CCD) and artificial neural network (ANN) were utilized and compared to each other in order to obtain appropriate predicting model with respect to sonication power (w), sonication time (min) and water/reactor volume r...

the aim of this research is to investigate the relationship between leader – member exchange and organizational citizenship behavior, and considering the mediating role of psychological empowerment and organizational commitment. the sample consisted of 250 employees of marun oil and gas producing company who were selected by simple random sampling method. the instruments which used in this rese...

Observations of gamma-ray bursts up to $z\sim 9$ are best suited study the possible evolution Universe equation state at intermediate redshifts. We apply Combo-relation a sample 174 gamma ray investigate evidence evolving dark energy parameter $w(z)$. first build burst Hubble's diagram and then we estimate set ($\Omega_m$, $\Omega_{\Lambda}$) in framework flat non-flat $\Lambda$CDM paradigm. ge...

soil hydraulic properties are key soil physical characteristics that are required to conduct soil and water related studies such as irrigation and drainage. in this study, three indirect methods: inverse modeling, pedo-transfer function, and the semi-physical method of arya et al., were compared in a sandy loam soil to estimate soil moisture retention and unsaturated hydraulic conductivity curv...
