Introduction: Scoliosis is a lateral spinal deformity of 10 degrees or more, resulting in a C-shaped or S-shaped curve of the spine. Information about adolescent idiopathic scoliosis (AIS) prevalence rate is important not only for paediatric health care planning strategy but also for parent's awareness. This study aims to find the suitable inclination cut-off angle and the prevalence rate of AI...

in this paper, the properties and microstructure of foam glasses obtained from the wasted cathode ray tube (crt) display panels were investigated. the foam glasses were prepared at the temperatures of 850, 950 and 1050c using 2, 4, 6 and 8 wt.% silicon carbide (sic) as the foaming agent. the physical and mechanical properties of the samples including the density, porosity, four-point bending s...

This study investigated the relationship between acoustic emission (AE) signals parameter sequence fractal characteristics and damage evolution information of corroded reinforced concrete (RC) beams under four-point bending. Strength deterioration behavior AE data can be obtained by coupling bending test monitoring. The results show that ringing counts uncorroded had prominent characteristics. ...
