In order to analyze the crack closure of a fatigue crack, nonlinear ultrasound is applied. In introduction of fatigue crack we develop the crack opening monitoring procedures using TOFD method to obtain the reliable result about the relation between crack opening displacement and nonlinear ultrasound. Longitudinal ultrasonic wave of 6.4MHz in frequency with(More)
It has been reported that planula larvae of some jellyfish prefer artificial substrates for settlement. This research focused on the relationship between the settlement of planulae and the wettability of artificial substrate surfaces. We used atmospheric plasmas to change the wettability of the surfaces of polycarbonate (PC) plates because plasma treatment(More)
BACKGROUND The aim of this study was to identify the correlation between the location of the internal carotid artery (ICA) and the need for an orbitozygomatic approach (OZA) when approaching a basilar apex (BX) aneurysm. MATERIALS AND METHODS By imaging the virtual trajectory to access the basilar artery (BA) through the ICA, the correlations among the(More)
