A prospective controlled trial was carried out to assess the effect of using a wound isolator on reducing postoperative infection. A total of 291 patients undergoing hip pinning for fractures of the neck of femur entered the trial and were allocated at random to have their wound contained in a wound isolator (study group) or dressed with a standard gamma-irradiated adhesive dressing (control gr...

The coupled lateral–torsional stochastic response of an asymmetric one-storey base isolated building to earthquake excitation is presented. The stochastic model of the 1940 El-Centro earthquake, which preserves the non-stationary evolution of the amplitude and frequency content of the ground acceleration, is used as earthquake excitation. The base isolator consists of an array of elastomeric be...

Compliant Mechanism has been designed for various types of application to transmit desired force and motion. In this study, we have explored an application of Compliant Mechanism for passive vibration isolation systems, for which compliant isolator is used to cancel undesired disturbance, which results in attenuated output amplitude. The Compliant Mechanism is equipped with isolator, which acts...

We illustrate two different, but complementary, applications of lithium (Li) isotope tracers for river-basin characterization at different scales within the Loire River basin (LRB) in France. The first example deals with behaviour Li and fractionation its isotopes during river weathering scale LRB (117,800 km2). wide ?7Li range (+5.0 to +13.3‰) streams, spatialized between headwaters lowlands, ...

The Isolator 10 lysis-centrifugation blood culture system (E. I. du Pont de Nemours & Co., Inc., Wilmington, Del.) and the BACTEC 16B-17D radiometric resin system (Johnston Laboratories, Inc., Towson, Md.) both remove antimicrobial agents from the blood for culture. We compared these two systems for recovery of aerobic bacteria, facultatively anaerobic bacteria, and yeasts. A total of 5,000 blo...

Abstract Background The resonant-frequency-tunable vibration isolator based on Shape Memory Alloys (SMAs) combines the priority of passive and active isolators, expands its engineering application, improves efficiency isolation. However, special characteristics SMAs complexity result in difficulty finite-element analysis. Methods This article employs ABAQUS subroutine presents analysis for this...

I will refer to the results appearing in the paper " Semigroups, rings, and Markov chains " by the numbers under which they appear in this paper (specifically , in its version of 20 June 2000, which appears on arXiv as preprint arXiv:math/0006145v1). Errata • Page 1, §1: " explcitly " → " explicitly ". • Page 3, §1.4: Replace " q-elements " by " q elements ". (The hyphen should not be there.) •...

Although Lebanon has the highest mean annual rainfall of all Middle Eastern countries, it is affected by water stress, negatively impacting agricultural food production, energy generation, and undermine ecosystem functions. The Bekaa area, where upper Litani River Basin (LRB) located, suffers serious quality quantity problems, which threaten productivity public health. Most domestic industrial ...

Wire rope isolator is widely used in the field of vibration isolation and shock resistance naval equipment. To overcome shortcomings poor tensile performance traditional wire isolator, a new biaxial compression was designed, characteristics isolators spherical were tested using test methods. By conducting comparative experiment, difference are studied. The frequency sweep results ...
