This paper aims to examine the relationship between the structural and performance variables in 140 Iranian industries, Co-Wash besides investigating structure of industrial markets according to the Four-firm concentration ratio plus cost advantage ratio (CDR).Then the study estimates efficiency level of the industries under the stochastic frontier
Associative stimulation of the supraorbital nerve fails to induce timing-specific plasticity in the human blink reflex.
BACKGROUND: Associative high-frequency electrical stimulation (HFS) of the supraorbital nerve in five healthy individuals induced long-term potentiation (LTP)-like or depression (LTD)-like changes in the human blink reflex circuit according to the rules of spike timing-dependent plasticity (Mao and Evinger, 2001).HFS given at the onset of the R2 co
An HR-Induced Tobacco Peroxidase Gene Is Responsive to Spermine, but Not to Salicylate, Methyl Jasmonate, and Ethephon
Leather Lead In Tobacco mosaic virus (TMV)-infected tobacco plants carrying the N resistance gene, a hypersensitive reaction or response (HR) occurs to enclose the virus in the infected tissue.Although a contribution of peroxidases to the resistance has been proposed, no evidence has been presented that tobacco peroxidase genes respond to HR.Here,
Short-term restoration practices change the bacterial community in degraded soil from the Brazilian semiarid
Abstract Land degradation by deforestation adversely impacts soil properties, and long-term restoration practices have been reported to potentially reverse these effects, particularly on soil microorganisms.However, there is limited knowledge regarding the short-term effects of restoration on the soil bacterial community in semiarid areas.This stud
