Bring Your Own Device (BYOD) is a business policy that provides flexibility and productivity to the employees of companies, organizations, or establishments adopt it. In this work, study was carried out know formal use personal mobile devices for work activities, using collection techniques such as surveys interviews. sense, it analyzed whether not people officially BYOD. The main results showe...
BACKGROUND Surgical site infection (SSI) is a common complication following abdominal surgery. It is associated with considerable morbidity and mortality, and its management results in significant cost to health services within both primary and secondary care. Some surgeons believe that the use of a wound-edge protection device may reduce the incidence of SSI. Whilst there is some encouraging e...
Distal embolization of particulate matter complicates percutaneous coronary and peripheral interventions more often than had been recognized until recently. A number of distal protection devices are under development. The PercuSurge GuardWiretrade mark is a balloon occlusion thrombectomy device approved by the United States Food and Drug Administration for saphenous vein graft intervention. A n...
To compare the effectiveness of cromolyn sodium (CS) (10 mg) and nedocromil sodium (NS) (4 mg) administered by a metered dose inhaler (MDI) with a spacer device in preventing exercise-induced asthma (EIA), eight asthmatic children with EIA were studied in a randomized double-blind, cross-over, placebo-controlled study, CS and NS provided significant, comparable protection from EIA and both were...
Staphylococcus aureus is a leading cause of ventricular assist device-related infections. This study evaluated the protective effect against S. aureus infection of active and passive immunization that targeted 3 proteins involved in bacterial attachment to a murine intra-aortic polyurethane patch. Active immunization of mice with a combination of the A domains of clumping factor A (ClfA), fibro...
Research Motivation Effective on-chip ESD design to solve the ESD protection challenge on the analog pins for highfrequency or current-mode applications is studied. The device dimension of ESD clamp devices in analog ESD protection circuit can be reduced to have a much small input capacitance for high-frequency applications, but it can still sustain a high HBM and MM ESD level. To find the opti...
This tutorial paper reviews the state of knowledge of on-chip ESD (electrostatic discharging) protection circuit design for integrated circuits. The discussion covers critical issues in ESD design, such as, ESD test models, ESD failure mechanism, ESD protection structures, ESD device modeling, ESD simulation, ESD layout issues, and ESD influences on circuit functionality, etc. This review serve...
BACKGROUND Occupational noise-induced hearing loss (NIHL) occurs in many industries despite interventions such as hearing conservation programmes. AIMS To determine the actual and reported use of hearing protection devices (HPDs) in noise-exposed gold mine workers and their reported knowledge, attitudes and practices relating to NIHL and HPDs. METHODS A cross-sectional descriptive study was...
