BACKGROUND Dental injury as a result of oroendotracheal intubation during general anesthesia is very common. We report our experiences of using mouthguard to prevent dental injury during intubation based on our protocol. METHODS This retrospective study enrolled patients referred for preanesthetic evaluation, those patients with a history of any of the dental treatments to their anterior teet...

BACKGROUND When engineering controls such as ventilation are not sufficient to prevent hazardous exposures in workplaces, respiratory protective devices (RPDs) may be provided to decrease workers' exposures. Often, workers do not use RPDs consistently when required. AIMS Our goal was to determine important factors associated with RPD usage in workers with respiratory disease exposed to airbor...

This paper presents a Monte Carlo approach for reliability assessment of distribution systems with distributed generation using parallel computing. The calculations are carried out with a royalty-free power flow simulator, OpenDSS (Open Distribution System Simulator). The procedure has been implemented in an environment in which OpenDSS is driven from MATLAB. The test system is an overhead dist...

Several surveys showed that cardiopulmonary bypass (CPB) is associated with incidents that negatively affect outcome and suggested that improved monitoring and safety could be associated with a decreased rate of incidents. In 2004, the French "Haute Autorité de Santé" (an independent French government advisory agency) and the French College of Perfusion issued recommendations concerning safety ...

Transmission of bacteria from inanimate surfaces in healthcare associated environments is an important source of hospital acquired infections. A number of commercially available medical devices promise to fulfill antibacterial activity to reduce environmental contamination. In this study we developed a touch transfer assay modeling fingerprint transmission to investigate the antibacterial activ...

Seismic protective devices in the form of isolation and supplemental damping devices can be effective means in mitigating the seismic responses of structures. The required stiffness and damping values to achieve optimal performance depend on the characteristics of structures and ground motions. Instead of using actively controlled devices, one can select the passive devices to roughly mimic the...

In this paper, simultaneous placement of distributed generation, capacitor bank and protective devices are utilized to improve the efficiency of the distribution network. The objectives of the problem are reduction of active and reactive power losses, improvement of voltage profile and reliability indices and increasing distribution companies’ profit. The combination of firefly algorithm, parti...

In the field of aerosol filtration, electrostatic effects are relatively unexplored but absolutely decisive in many applications (Rengasamy, 2009). It is possible to adjust and improve the particle deposition for synthetic filter materials to increase the initial filtration efficiency. E.g. it is used in respiratory protective devices, cabin air filters or air conditioning systems. The measurem...

COMPARISON OF ATTENUATION CHARACTERISTICS OF THE ACOUSTIC REFLEX AND THE V-5IR EARPLUG OBJECT To compare the attenuation characteristics of the acoustic reflex and the V-5IR earplug, RESULTS Pre-and post-exposure thresholds were obtained for 13 subjects exposed under two conditions to 100 rounds of machine gun fire (fired one round at a time). In condition I the acoustic reflex (AR) was activat...
