Background and aims: This study aimed to evaluate the effect of enforcement of new traffic laws on the fatal and non- fatal injury rates in Iran. Methods: In a longitudinal, interventional controlled trial study, all subjects with history of fatal and non-fatal injuries were studied. Their injuries were caused by six risky violations (unauthorized speed, illegal overtaking, red traffic light c...

Various mutations altering the herbicide target site (TS), can lead to structural modifications that decrease binding efficiency and results in herbicide resistant weed. In most cases, such a mutation will be associated with ecological fitness penalty under herbicide free environmental conditions. Here we describe the effect of various mutations, endowing resistance to acetyl-CoA carboxylase (A...

trees are an important source of wild germplasm for sustainable forestry. wild pear germplasm (pyrus boisseriana) was collected from a forest ecosystem and resistance potential to drought stress was surveyed in a greenhouse. in six-month seedlings, signs of leaf rolling appeared after 18 days without water (drought simulation). gas exchange parameters, such as net photosynthesis, stomatal condu...

Thrips is one of the most harmful insect groups attacking many field and vegetable crops. Predatory mites, especially those in family Phytoseiidae, are considered as good bioagents to control thrips where application of chemical pesticides can be decreased. This work was conducted to evaluate the efficacy of the two phytoseiid mites, Amblyseius swirskii (Athias-Henriot) and Neoseiulus cucumeris...

Exposure of epidermal keratinocytes to UVB radiation leads the intracellular formation tryptophan photoproducts which subsequently activate aryl hydrocarbon receptor (AHR) induce mal-/adaptive stress responses. Previously, we have found that AHR represses nucleotide excision repair and apoptosis in UVB-irradiated thereby contributes skin photocarcinogenesis mice. The mechanisms by interferes wi...

BACKGROUND AND AIMS Selective feeding by herbivores, especially at the seedling or juvenile phase, has the potential to change plant traits and ultimately the susceptibility of surviving plants to other enemies. Moreover, since hybridization is important to speciation and can lead to introgression of traits between plant species, differential feeding (herbivore-induced mortality) can influence ...

Today, planting winter cover crops to reduce herbicide is high considered. The purpose of this study was to examine the effect of barley grass cover crop on control weed of flix weld (Descurainia Sophia). This experiment was conducted at agricultural farm of Rezvan Junior College in kerman provinces (latitude 25 55 / N, longitude 53 26 / E , altitude 1755m) from September 2010 to April 2011. A ...

Tuta absoluta, Bemisia tabaci and Macrosiphum eurphorbiae are important pests of tomato in Cameroon. The effect EM a biopesticide containing Bacillus thuringiensis as active ingredient was evaluated on the suppression these pests. A completely randomized design with 4 treatments [control (T0); 10 ml/l (T1); 20 (T2); 30 (T3)] 3 replications were used. sprayed weekly for seven weeks. variation in...
