The purpose of this in vitro biomechanical study is to determine the force attenuation capacity of four different hip protectors (KPH1, KPH2, Safehip, and Safetypants) in falling simulations in elderly subjects (falls to the side). The simulated falling conditions were created by a biomechanical testing system, which consisted of an impact pendulum, surrogate pelvis and femur, and two load cell...

Because many preventable medication errors occur at the ordering stage, a program for improving the quality of writing inpatient orders and outpatient prescriptions at one institution was developed. To determine whether potential problems existed in the order-writing process for inpatients, all physician orders for a seven-day period in 1997 were reviewed (n = 3740). More than 10% of all orders...

In wireless networks, the presence of interference among wireless links introduces dependencies among flows that do not share a single link or node. As a result, when designing a resource allocation scheme, be it a medium access scheduler or a flow rate controller, one needs to consider the interdependence among nodes within interference range of each other. Specifically, control plane informat...

Abstract Reconstructed whole-rock (RWR) and mineral major- trace-element compositions, as well new oxygen isotope data, for 22 mantle eclogite xenoliths from the Catoca pipe (Kasai Craton) were used to constrain their genesis evolution. On basis of mineralogical major-element eclogites can be divided into three groups: high-alumina (high-Al) (kyanite-bearing), low-magnesian (low-Mg#), high-magn...

The magnetopause locations as determined by the Explorer 12 SpL charged-particle detector and the Imp I plasma experiment can be used to study the relation between the solar wind parameters and geomagnetic activity. As will be seen, no strong correlation is evident between the size of the magnetosphere, as determined from magnetopause crossings, and geomagnetic activity indexes. It is argued th...

Many different procedures have been suggested for use in hearing aid selection: the practicing audiologist must choose among them. A structured approach to the hearing aid selection process is most likely to result in an optimal choice for each patient. This paper describes one such approach to the process of hearing aid selection which attempts to customize the selection procedure to make maxi...

This paper presents a simple, efficient and cost effective routing strategy that considers deadlock recovery as opposed to prevention. Performance is optimized in the absence of deadlocks by allowing maximum flexibility in routing. Disha supports true fully adaptive routing where all virtual channels at each node are available to packets without regard for deadlocks. Deadlock cycles, upon formi...

Herein we discuss the impact of microRNA (miRNA) target genetic variability in male infertility genes, which can represent a source of novel molecular-genetic markers that can be used for the diagnosis of male infertility. Male-factor infertility accounts for 30%–40% of infertility cases. The causes of spermatogenetic failure found in most cases of non-obstructive azoospermia or severe oligozoo...
