Wind erosion is one of the environmental problems worldwide, particularly in arid and semi-arid areas of Iran. Different methods and models have been proposed to measure and monitor wind erosion in the recent years. One of the accurate models for measuring f wind erosion is the USEPA model. The purpose of this study was to evaluate the quantification of wind erosion with the USEPA model and the...
purpose: to evaluate the success rate of bicanalicular silicone tube intubation in children with congenital nasolacrimal duct obstruction (cnldo). methods: hospital records of 71 cases of bicanalicular silicone intubation in 62 children with cnldo were reviewed. success was defined as resolution of symptoms and signs such as epiphora and discharge 6 months after removal of the silicone tube. re...
The importance of the equipment and secondary systems in seismic design and performance evaluation is well recognized and has been the subject of many studies. In all of these studies, earthquake is considered as a single component, and in most of them the primary system is considered as shear building. Most attention has been concentrated on the response of secondary system and its response sp...
