Hearing loss (HL) is the most frequent sensory defect affecting 1 in 1000 neonates. This can occur due to genetic or environmental causes or both. The genetic causes are very heterogenous and over 100 loci have been identified to cause autosomal recessive non - syndromic hearing loss (ARNSHL). The aim of this study was to determine the contribution of the LRTOMT gene mutations in causing ARNSHL...

in order to investigate biodiversity of industrial crop in iran, an investigation was made based on the statistical data available on acreage and production of this crop in the country. cultivated area of industrial crop from 29 provinces were analyzed and shannon biodiversity index was calculated. the highest biodiversity index compare to the total crop species was observed in golestan, semnan...

increasing industrial activities lead to entrance of different pollutants into the environment, especially water resources. because of their persistency and non-biodegradation, metals can pose a threat to health of human and other organisms. sediment, fish (lucioperca stizostedion and cyprinus carpio), and common reed (phragmites australis) samples were collected from sattarkhan dam for investi...

abstract the use of water sources has increased due to extend of agricultural activity for answering food needs of increasing population. while because of exploitation and consumption of water, the use of this restricted resource is not appropriate. consequently in many districts of country the head level of ground water aquifers have been fallen and water level is negative. so, application of ...

The impact of blast-driven shocks on the safety and stability of the underground coal mines has been well established. The seismic imperfections resulting from blasting depend on the total explosive energy released during blasting and the closeness of the development tunnel face to the stope face. Also, the quality of the rock mass wherein the whole stope face is located might pose considerable...
