the kuhshah ultramafic complex is located in the south-east of sanandaj-sirjan metamorphic zone, near the probable remnants of neotethys plate in iran. it consists of highly depleted harzburgites, dunites, chromitite bands and altered gabbros. the ultramafic parts have been intruded by numerous clinopyroxenite dykes and veins. in the harzburgites, there are different generations of olivine, ort...

results a total number of 20 out of 1772 (1.12%) examined students were found to be infested by lice. although the infestation rate was higher in girls, the difference of infestation rate between genders was not statistically significant (p > 0.05). the rate of head lice infestation was siginificantly (p < 0.05) correlated to their hair-washing behavior. parents’ literacy level also was siginif...

As an industrial economic organization with specific characteristics, industrial cluster is emerging with strong dynamism in global competition and driving the development of regional economy. However, industrial cluster can bring some negative impact on regional economy development. This paper tries to illustrate the reasons for the stagnation and degradation of resource-based regional industr...

Several physical parameters and anisotropy related to rock textural arrangements, schistosity weakness planes such as cracks joints affect the P-wave velocity (VP). First, VP of quartz-mica schist a common type widespread metamorphic was compared with jointed homogeneous limestone specimens clarify effect these two different types anisotropies. The results showed that texture is stronger than l...
