chemical insecticides have been widely employed for the control of storage grain pests. this has caused such problems as insecticide resistance along with contamination of foodstuffs with chemical residues. thus, there is a growing interest in using pathogenic control agents as alternative. in this study, the potential of beauveria bassiana (bbweevil™, a commercial product containing 2×109 coni...
INTRODUCTION Mechanical impact loading is known to cause cell death and to lead to the onset and progression of osteoarthritis [1]. In order to understand why in-situ cells die readily following impact loading but remain unaffected when the same load is applied at a slow rate, we used a Finite Element model of articular cartilage and chondrocytes to study the in-situ cell mechanics, which canno...
Land application of biosolids is a beneficial-use practice whose ecological effects depend in part on hydrological effects. Biosolids were surface-applied to square 0.5-m2 plots at four rates (0, 7, 34, and 90 dry Mg ha(-1)) on each of three soil-cover combinations in Chihuahuan Desert grassland and shrubland. Infiltration and erosion were measured during two seasons for three biosolids post-ap...
this study examined the effects of collaborative strategic reading and direct instruction in persuasion on iranian high school students persuasive writing and attitudes. students in three intact classes were assigned to one of three treatment conditions: collaborative strategic reading and direct instruction in persuasion or direct instruction in persuasion or a control group. treatment effects...

In order to clarify the fates of fertilizer N in coastal saline soil-wheat systems with different salinization degrees, this study was conducted determine 15N uptake rates various parts wheat plant at maturity stage and residual three soils loss by using 15N-labeled urea tracing method Yellow River Delta. The results showed that: (1) increase soil salinity from 0.2% 1% promoted absorb not signi...
to explore the idea the investingation proposed, aimed at finding whether the performances of the population of iranians students studying english in an efl context are consistent in l1 and l2 writing taks and whether there is a cross-linguistic transfer in this respect. in this regard the subjects were instructed to write four compositions-two in english and two in farsi-which consisted of an ...
Rapeseed as one the most crops is the basic needs of human feeding in order to produce oil. A field experiment was conducted to study the effects of different tillage system, seeding method and rates on yield and its components, as well as, seed oil percentage of rapeseed (Brassica napus L. cv. Hyola-401) during 2011-12 growing season at Rice Research Institute of Iran-Department of Ma...
Various energy recovery, storage, conversion and environmental operations may involve repetitive fluid injection thus, cyclic drainage–imbibition processes. We conducted an experimental study for which polydimethylsiloxane (PDMS)-based micromodels were fabricated with three different levels of pore-space heterogeneity (coefficient variation, where COV = 0, 0.25 0.5) to represent consolidated an...
