abstractbackground: although electronic portal imaging devices (epids) have originally developed for positioning verification, they can also be used for dosimetric purposes. in the current work, the dose response of minimum detectable thickness of a scanning liquid filled ion chamber epid, slic-epid, and the variation of transmitted dose with the shift of inhomogeneity inside of phantom was als...

The morphology of 11 species of the genus Vicia from Iran was studied using Scanning Electron Microscopy (SEM). The main pattern in seed coat sculpturing in the species was papillose, but the size and the number of side ribs in papillae and the density of papillae, were different in various species. Four morphological characters of seeds: relative hilum length and shape, relative position of th...

Abstract: current densities. Electrochemical impedance spectroscopy (EIS) results showed that the codeposition mechanism oftungsten in Ni-W deposition is the reduction of tungsten oxide which changed to the reduction of tungsten-containingion complexes at higher current densities. In Co-W electrodeposition, the tungsten codeposition takes place viareduction of tungsten oxide, although, the role...

in this research with using of obtained information from a natural fraxinus the variation of quantities and qualitative measures of current stand in an 8 year period was conducted in chelir part of kheyroud forest. data collection was conducted by full callipering method in two periods of 1384 and 1392. during the period of study the parameters of dominant mean height and relative crown height ...

Background: Thermoluminescence dosimetry is one of the dosimetry procedures used widely as routine and personal dosimeters. In order to extend this kind of dosimeters, dental tissue has been examined and was found promising as a TLD dosimeter. Materials and Methods : In this study, 70 health teeth were collected. The only criterion, which was considered for selection of the teeth, was the healt...
