background: this study was aimed to compare the diagnostic accuracy and feasibility of cone beam computed tomography (cbct) with phosphor storage plate (psp) in detection of simulated occlusal secondary caries. materials and methods: in this in vitro descriptive-comparative study, a total of 80 slots of class i cavities were prepared on 80 extracted human premolars. then, 40 teeth were randomly...

Carbonate rocks have a wide variety of pore shapes and different types grains, which greatly affect the elastic properties characteristics reservoir. This causes certain difficulties in petroelastic modeling. One problems is scale input data, then used to build rock physics model. The paper presents results studying three core samples carbonate Upper Devonian Lower Carboniferous age, are locate...
