this study investigated the influence of nanoclay on the impact damage resistance of glass fiber-epoxy composites under high velocity ice impact loading. addition of 0.5 wt. % nanoclay into epoxy was shown to improve damage resistance compared to composite plates having no nanoclay platelet. the glass fiber-epoxy composites containing nanoclay brought about substantial improvement in ice impact...

thrips tabaci is one of the most important pests causing serioues damages on onion s in iran despite several chemical sprayings. to assess the population density and damage of the thips on onion, improved sefid-e-khomein genotype along with seven other iranian cultivars of onoin were planted in a rcb design with four replications in two separate experiments (sprayed and non-spray ed ) in arak f...

the log damage and value loss were examined by felling and bucking function, species, and damage type, in kheyrud forest in namkhaneh district in the hyrcanian forest of iran. in order to calculate the wood value following tree felling and bucking, 250 trees and 167 logs consisting of beech and hornbeam species were measured. there were five types of damage recorded following the tree felling o...
