The growth front of nacreous layer, which lies just above the outer prismatic layer, is one of the crucial areas to comprehend the formation of nacreous aragonite. The crystallographic properties of aragonite crystals at the growth front in pearl oyster, Pinctada fucata, were investigated using scanning electron microscopy with electron back-scattered(More)
In this study, the evaluation of audio-visual interaction regarding to the sounds and colours of trains was investigated. Different pictures of trains were modified in their colors and presented on a liquid crystal screen in a sound proof room with the appropriate sound of the train. The subjects judged the loudness of the sound-picture stimuli with the(More)
The aim of the study was to examine the relationship between pitching ball velocity and segmental (trunk, upper arm, forearm, upper leg, and lower leg) and whole-body muscle volume (MV) in high school baseball pitchers. Forty-seven male high school pitchers (40 right-handers and seven left-handers; age, 16.2 ± 0.7 years; stature, 173.6 ± 4.9 cm; mass, 65.0(More)
OBJECTIVE This study was designed to test the feasibility of several types of enhancements for cephalometric computed radiographs through use of the Fuji Computed Radiography system (Fuji Photo Film Corp., Tokyo, Japan). STUDY DESIGN The material consisted of four lateral cephalograms made with the Fuji Computed Radiography system that were enhanced by(More)
AIM The aim of the present study was to investigate the influence of anti-tumor necrosis factor (anti-TNF) agents on gait function in patients with rheumatoid arthritis (RA). METHODS Nine subjects with RA who were being treated with anti-TNF agents, participated in this study. A motion capture system was utilized, and data from the force plate and(More)
The purpose of this study was to identify the correlation between throwing motion and maximum elbow varus torque (MEV) in female professional baseball pitchers. Twelve pitchers without pre-existing pain were recruited. Ball velocity and pitching motion were measured. Ball velocity and, kinematic and kinetic data from each joint during the pitch were(More)
This study examined anthropometric and fitness profiles of Japanese female professional baseball players and investigated the relationship between players' physical fitness and in-season game performance. Fifty-seven players who were registered in the Japan Women's Baseball League (JWBL) participated. Height, weight, grip strength, back strength,(More)
