BACKGROUND Pressure ulcers are a prevalent and global issue and support surfaces are widely used for preventing ulceration. However, the diversity of available support surfaces and the lack of direct comparisons in RCTs make decision-making difficult. OBJECTIVES To determine, using network meta-analysis, the relative effects of different support surfaces in reducing pressure ulcer incidence a...

Longwall mining is the only technically proven and established method worldwide for coal extraction at greater depth. In this paper, 2D plane strain finite element models of longwall panels are developed and analyzed to understand the interaction of hydraulic powered support with surrounding rock strata. Based on Indian geomining conditions, finite element models are developed including the str...

because of the everyday use of power generators in iraq, which exist in residential neighborhoods, it is necessary to study the impact on soils and plants surrounding areas of those generators. lead is one the most heavy metals released especially, as a result of the combustion of diesel fuel during operation of the powered generators. however, a study was conducted to investigate the lead conc...

Exoskeletons comprised of rigid load-bearing structures have been developed for many years, but a new paradigm is to create “exosuits” that apply tensile forces to the body using textiles and utilize the bodys skeletal structure to support compressive forces. Exosuits are intended to augment the musculature by providing small to moderate levels of assistance at appropriate times in the walking ...

The purpose of this research was to examine whether exercisers and nonexercisers are rated similarly on a variety of characteristics by a sample of randomly selected regular exercisers, nonexercisers who intend to exercise, and nonexercisers with no intention to exercise. Previous research by Martin Ginis et al. (2003) has demonstrated an exerciser stereotype that advantages exercisers. It is u...

In this paper, a feasibility study of building a Human Powered Hydrofoil (HPH) vessel is reported. Hydrofoil vessels are a well-known class of high-speed crafts. In addition to high-speed operation, the hydrofoils have a reliable maneuvering capability, good stability and proper operation in waves. Also, a human powered vehicle, nowadays is an advancing idea. Different aspects of the design and...
