The purpose of this study was to evaluate the radiopacity of 5 root-end filling materials (white MTA-Angelus, grey MTA-Angelus, IRM, Super EBA and Sealer 26). Five specimens (10 mm diameter X 1 mm thickness) were made from each material and radiographed next to an aluminum stepwedge varying in thickness from 2 to 16 mm. Radiographs were digitized and the radiopacity of the materials was compare...

While Cadmium Telluride (CdTe) excels in terms of photon radiation absorption properties and outperforms silicon (Si) this respect, the crystal growth, characterization processing into a detector is much more complicated. Additionally, large concentrations extended crystallographic defects, such as grain boundaries, twins, tellurium (Te) inclusions, vary from to can reduce spectroscopic perform...

Red mud or bauxite residue contains significant quantities of industrial metals such as Fe, Al, and Ti, well rare earth elements Sc, Ce, La. The authors performed a laboratory-scale project dealing with stepwise recovery valuable from two residues, namely Iranian red (IRM) Turkish (TRM). first stage involved the iron which was present in large mud. Two different methods were investigated for th...

We are interested in learning robust models from insufficient data, without the need for any externally pre-trained checkpoints. First, compared to sufficient we show why data renders model more easily biased limited training environments that usually different testing. For example, if all swan samples “white”, may wrongly use “white” environment represent intrinsic class swan. Then, justify eq...
