Introduction: The existing bone is regarded as an important criteria in dental implants. In this regard, the radiographic modality is of great significance in quantifying the remaining bone, and CBCT accurately represents height and width of the existing bone. Therefore, this study aimed to evaluate the frequency distribution of the edentulous posterior mandibular ridge types using cone beam co...

To design cost-effective and efficient drip irrigation systems, it is necessary to know the vertical and horizontal advance of the wetting front under the point source; also, the proper management of drip irrigation systems requires an awareness of the soil water distribution. Many factors influence wetting pattern dimensions, including discharge, land slope, irrigation time and soil texture. T...

Physiological studies indicated that flag leaf has high contribution in wheat grain yield. In addition, number, distribution, and morphology of stomatal characteristics are important traits in the drought resistance and adaptation of wheat cultivars to fluctuating CO2 levels. A complete set of diallel crosses among seven durum wheat lines were used to study of genetic parameters of stomatal and...

Study area, Danekhoshk anticline, is a typical growing anticline in Kermanshah province and is located in Folded Zagros structural Belt. The purpose of this research is to calculate the eroded rock volume and its relationship with tectonic in Danekhoshk anticline. To achieve the purpose of this study, at first, boundaries of 90 drainage basins on slopes of studied anticline were determined base...

Morphotectonic is one of the new reconition methods of tectonic movements and earthquakes knowledge. Study and measurement of landscapes and forms which made by active tectonics are important objects in morphology science. Active tectonic movements have recorded in the morphology of rivers, drainages, alluvial fans and mountain fronts in a region. Research area is located between 55° 30' -57° 0...
