Introduction: The low regeneration of bone in defective bones causes therapeutic problems. Various strategies to assess the healing of bone defects have been used which they include histological and histo-chemical analysis in an invasive study. The purpose of this study was to determine the ultrasonic parameters of bone as a promising noninvasive technology for assessing bone repair process. Ma...
The aim of this study is to evaluate the effect of edible gelatin concentration as a polymerization agent on MAGIC-f polymer gel dose-response sensitivity irradiated by 1.25 MeV energy of cobalt-60. To investigate the dose-dependent polymerization, ultrasonic parameters of propagation speed of sound and broadband ultrasound attenuation coefficient were evaluated. To read-out of the radiation-in...
The movement parameters of yellow fin tuna schools were analyzed by means of scanning sonar in tuna purse seine capture situations in the Oman Sea in June 2010. There was significant difference in swimming speed and radial swimming direction between the escaped and captured schools. In escaped cases, the fish schools swam faster with mostly horizontal avoidance behavior to the sound stimuli fro...
