desertification is recognized as a serious environmental threat in iran because of its climatic-geomorphologicconditions. desertification and land degradation in arid, semi-arid, and dry sub-humid regions, is a globalenvironmental problem. accurate assessment of the status and trend of desertification is instrumental in developingglobal strategies to prevent and reverse this problem. the goal o...

introduction soil losses and erosion is one of the main causes of fertility decreasing, sedimentation in river cannels and irrigation canals, decreasing of storage capacity in dams, increasing of floods frequency, environmental pollution and it prevents from stable development. more than 70% of iran land is covered with arid and semi-arid areas. soil erosion as one of the main causes of soil de...

Background and Aim: Brain mapping is a study of the anatomy and function of the CNS (central nervous system). Brain mapping has many techniques and these techniques are permanently changing and updating. From the beginning, brain mapping was invasive and for brain mapping, electrical stimulation of the exposed brain was needed. However, nowadays brain mapping does not require electrical stimula...

OBJECTIVE To determine the rate and performance of sentinel lymph node (SLN) mapping among women with high-risk endometrial cancers. METHODS Patients diagnosed between 2012 and 2015 with uterine cancer of grade 3 endometrioid, clear cell, serous or carcinosarcoma histology and who underwent SLN mapping prior to full pelvic lymph node dissection were included. Subjects underwent methylene blue...

In this study, it is attempted to analyze sensitivity and reliability in order to evaluate the liquefaction potential in soil layers in Tabriz. 62 boreholes that had possible conditions for liquefaction were selected. Seismic mapping was simulated using finite fault method and then the effect of soil layers on PGA was estimated. In continue, the liquefaction potential index was estimated and th...
