مقدمه: آگاهی از خصوصیات مهم کلینیکی، رادیوگرافیک و هیستولوژیک کیست های ادنتوژنیک و تشخیص افتراقی آن ها با یکدیگر و با ضایعات پاتولوژیک دیگر دهان و نیز طرح درمان پیش آگهی آن ها حایز اهمیت فراوان بوده و برای دندان پزشکان الزامی است. بنابراین در این مقاله، کیست های مزبور بر اساس ارتباط کلینیکوپاتولوژیک آن ها با یکدیگر، نه الزاماً به ترتیب شیوع، شرح داده می شوند. شرح مقاله: این مقاله با بررسی کتب مأ...
Monitoring with high resolution land cover and especially of urban areas is a key task that is more and more required in a number of applications (urban planning, health monitoring, ecology, etc.). At the moment, some operational products, such as the “Copernicus High Resolution Imperviousness Layer”, are available to assess this information, but the frequency of updates is still limited despit...
Digital Elevation Model (DEM) is main input for watershed modelling. Recently, available online free in different accuracies, and spatial resolutions as a product of several remote sensing satellites. Hence, it necessary to find out which one the best modeling study area. In this study, accuracies 30m resolution DEMs (Copernicus, SRTM, ASTER) can be examined by using Remote (RS) Geographic Info...
Sentinel-1A is the first satellite of the European Copernicus programme. Equipped with a Synthetic Aperture Radar (SAR) instrument the satellite was launched on April 3, 2014. Operational since October 2014 the satellite delivers valuable data for more than two years. The orbit accuracy requirements are given as 5 cm in 3D. In order to fulfill this stringent requirement the precise orbit determ...
GLORYS12 is a global eddy-resolving physical ocean and sea ice reanalysis at 1/12° horizontal resolution covering the 1993-present altimetry period, designed implemented in framework of Copernicus Marine Environment Monitoring Service (CMEMS). The model component NEMO platform driven surface by atmospheric conditions from ECMWF ERA-Interim reanalysis. Ocean observations are assimilated means re...
