Backgrounds and Objectives: Using seat belt has a considerable role in reducing human damage. The aim of this study was to compare trend of seat belt use rate during 4 years, from 2007 to 2010, in Golestan province (northern Iran). Materials and Methods: This was a population-based cross-sectional study that enrolled 3999 subjects aged 15-65 years during four years (2007 = 1000 cases, 2008 = 10...

We study the dynamical excitation that large planetesimals, scattered either by Neptune or Jupiter, could have provided to the primordial Edgeworth–Kuiper belt and the asteroid belt. Using both a refined Monte Carlo approach and direct numerical integration, we show that the Monte Carlo method is useful only to give qualitative insight into the resulting excitation, but cannot be trusted from a...

The systemic effects of wearing an industrial back belt for a repetitive asymmetric lifting task between knee and waist height have been investigated. Belt wearing significantly reduced the average heart rate by 5.3 beats per minute, constituting 21% reduction of the metabolic cost due to the exercise. Back belt significantly reduced the average systolic blood pressures by 9 mm of Hg. For manua...

Using energy absorption systems in the structures with malfunctioning components is of paramount importance. By absorbing the seismic energy, these systems help the components of the structure to remain resilient during earthquake. In the present study, viscous dampers were applied in order to enhance the reactions of tall building with belt truss. To assess the response of a structure un...

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...
