Background: Ventilator-Associated Pneumonia (VAP) is the most common nosocomial (hospital acquired) infection among patients undergoing mechanical ventilation. It increases mortality rate, duration of mechanical intubated ventilation, and hospitalization in the Intensive Care Units (ICUs). This review study aims to determine the proper gradient of a hospital bed in preventing VAP in patients ho...

The bed bug, Cimex lectularius L., like other bed bug species, is difficult to visually locate because it is cryptic. Detector dogs are useful for locating bed bugs because they use olfaction rather than vision. Dogs were trained to detect the bed bug (as few as one adult male or female) and viable bed bug eggs (five, collected 5-6 d after feeding) by using a modified food and verbal reward sys...

[1] We explored the dependence of experimental bedrock erosion rate on shear stress, bed load sediment flux, alluvial bed cover, and evolving channel morphology. We isolated these variables experimentally by systematically varying gravel sediment flux Qs and water discharge Qw in a laboratory flume, gradually abrading weak concrete “bedrock.” All else held constant, we found that (1) erosion ra...

BACKGROUND A culture of teamwork and learning from mistakes are universally acknowledged as essential factors to improve patient safety. Both are part of the Comprehensive Unit-based Safety Program (CUSP), which improved safety in intensive care units but had not been evaluated in other inpatient settings. METHODS CUSP was implemented beginning in February 2008 on an 18-bed surgical floor at ...

background the main purpose of this study was to explore the status of occupational stress among hospital nurses in isfahan, iran. it also aimed to examine the relationship between nurses’ occupational stress and their intention to leave the hospital.   methods the study employed a cross-sectional research design. a validated questionnaire was used to collect data from 296 nurses. respondents w...

The turnover of (131)I-labeled gamma globulin has been determined in rabbits before and during (8 weeks later) hyperimmunization with pneumococcic vaccine, which increased the gamma globulin concentration 5 to 10 times. Before immunization fractional turnover rate was an average of 36 per cent of the plasma pool per day, and the rate of catabolism was 133 mg/kg/day. During hyperimmunization fra...

The present study describes entrainment characteristics of bed material into debris flow, based on flume tests, numerical and dimensional analyses. Flume tests are conducted to investigate influences of bed sediment size on erosion rate by supplying debris flows having unsaturated sediment concentration over erodible beds. Experimental results show that the erosion rate decreases monotonically ...
