Rubber belt not only is one of the key components of belt conveyor, but also affects the overall performance of the core part. Research on dynamics analysis of large conveyor not only helps to improve the reliability and design level, but also can guide the rational selection of conveyor safety factor, and effectively reduce the cost of the conveyor belt. Based on unique viscoelastic properties...

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 under e...

BACKGROUND Omega-3 fatty acids from fish have been shown to have favorable effects on platelet aggregation, blood pressure, lipid profile, endothelial function, and ischemic stroke risk, but there are limited data on racial and geographic differences in fish consumption. METHODS Reasons for Geographic and Racial Differences in Stroke (REGARDS) is a national cohort study that recruited 30,239 ...

CONTEXT Despite scientific uncertainties about effectiveness, wearing back belts in the hopes of preventing costly and disabling low back injury in employees is becoming common in the workplace. OBJECTIVE To evaluate the effectiveness of using back belts in reducing back injury claims and low back pain. DESIGN AND SETTING Prospective cohort study. From April 1996 through April 1998, we iden...

This study estimated the effectiveness of seat belts in reducing injuries and estimated the associated economic benefits using state of Kansas data. The estimation process included three stages. In the first stage, seat belt effectiveness in reducing injuries to motor vehicle occupants was estimated. Crash data from Kansas Accident Reporting System (KARS) database was used to accomplish this es...

The Sarcos Treadport is a locomotion interface comprised of a large tilting treadmill, an active mechanical tether, and a CAVElike visual display. This paper presents the design specifications for the second-generation Sarcos Treadport. INTRODUCTION There have been various approaches towards the design of locomotion interfaces, including powered pedaling devices (Brogan et al., 1998), programma...

More than 50% of Parkinson’s disease (PD) patients exhibit freezing of gait (FoG) characterized by a sudden and transient inability to initiate or continue walking (1). The pathophysiology of FoG is still unknown, particularly due to the difficulty in reproducing this symptom spontaneously in the laboratory, either in humans or in animal models (2, 3). A current hypothesis proposes that FoG cou...

WHAT IS THE BLACK BELT? WHERE IS THE BLACK BELT? T he Black Belt is a string of counties that stretches from east Texas, through the deep South, and up into eastern Virginia. It is the largest, poorest, most rural region in the country. While definitions vary, the region typically is considered to encompass upwards of 623 counties across 11 states, mostly rural, crossing several smaller regions...

Van Allen radiation belts are typically two zones of energetic particles encircling the Earth separated by the slot region. How the outer radiation belt electrons are accelerated to relativistic energies remains an unanswered question. Recent studies have presented compelling evidence for the local acceleration by very-low-frequency (VLF) chorus waves. However, there has been a competing theory...

AN ARTICLE by Belušič and Zupančič (1) described the construction of a finger pulse sensor using a singing greeting card beeper. We felt that this beeper made of piezoelectric material could be easily modified to function as a respiratory belt transducer to monitor respiratory movements. Commercially available respiratory belt transducers, such as Pneumotrace (http:// www.adinstruments.com/prod...
