OBJECTIVES The objectives of this study were to investigate the influence of pelvic belts on the stability of the pelvis and to discuss the treatment of peripartum pelvic instability. STUDY DESIGN In six human pelvis-spine preparations, sagittal rotation in the sacroiliac joints was induced by bidirectional forces directed at the acetabula. Weight-bearing was mimicked by the application of a ...

Many problems which occur with belt conveyors can be attributed to system dynamics and the associated variations in belt tension. Material spillage, belt and splice failure, belt lift-off in vertical curves and poor tracking are a few examples of situations where knowledge of the dynamic tensions would be of benefit in eliminating a problem. The difficulty is that measuring dynamic tension at a...

The paper studies the breathing patterns for four types of Chinese metrical poems, namely, fivecharacter quatrain, five-character octave, sevencharacter quatrain and seven-character octave. A breathing belt was tied to the chest and the respiratory signal was acquired by EMG. Respiratory parameters were defined regarding the dynamical properties of the signal, and were automatically extracted b...

I discuss young close-by compact objects, recent supernovae in the solar neighbourhood, and point to their connection with cosmic ray studies. Especially the role of the Gould Belt is underlined.

4) The entire class of seat belt-related flexion-distraction injuries to the spine are commonly referred to as ‘Chance-type’ fractures. These fractures are caused by hyperflexion around a lap belt, with the belt acting as a fulcrum. This mechanism of hyperflexion and distraction would also explain the frequent association of intraabdominal injuries as viscera are crushed between the lap belt an...

Rear seat adult occupant protection is receiving increased attention from the automotive safety community. Recent anthropomorphic test device (ATD) studies have suggested that it may be possible to improve kinematics and reduce injuries to rear seat occupants in frontal collisions by incorporating shoulder-belt force-limiting and pretensioning (FL+PT) technologies into rear seat 3-point belt re...

OBJECTIVES The objective was to determine the association between the abdominal seat belt sign and intra-abdominal injuries (IAIs) in children presenting to emergency departments with blunt torso trauma after motor vehicle collisions (MVCs). METHODS This was a planned subgroup analysis of prospective data from a multicenter cohort study of children with blunt torso trauma after MVCs. Patient ...

In this research, we studied the fault recognition algorithm of steel cord conveyor belt, and obtained the wire ropes image by adopting the detection system of steel cord conveyor belt, so that the fault recognition algorithm of steel cord conveyor belt was proposed based on Fruit fly optimization algorithm. As we know that the fruit fly optimization algorithm is used for fault detection of the...

According to the actual working conditions of the Vribbed belt, automobile V-ribbed belt fatigue tester machine is designed to test for the automobile engine Vribbed belt fatigue wear. Finite-element analysis software ANSYS is employed to perform finite-element analysis on fatigue testing machine load shaft, bearing, universal joint key parts of the finite-element analysis, and to analyze the m...

Belt conveyor system is the transportation of material from one location to another location. Belt conveyor has high load carrying capacity (upto 30000 t/h), large length of conveying path (upto 3-4 km), simple design, easy maintenance and high reliability of operation. Belt conveyor system is also used various industries such as the material transport in foundry shop like supply and distributi...
