We have recently shown that waste heat from forced-air warming blankets can increase the temperature and concentration of airborne particles over the surgical site. The mechanism for the increased concentration of particles and their site of origin remained unclear. We therefore attempted to visualise the airflow in theatre over a simulated total knee replacement using neutral-buoyancy helium b...
We collected indoor air, surface wipes (floors, table tops, and window sills), and floor dust samples at multiple locations within 11 occupied and two unoccupied homes both before and after lawn application of the herbicide 2,4-D. We measured residues 1 week before and after application. We used collected samples to determine transport routes of 2,4-D from the lawn into the homes, its subsequen...
After introducing the central air-conditioning terminal units system, established a fuzzy control system based on Lonworks. System focuses on the design of fuzzy controller with intelligent nodes, Input signal of fuzzy controller were the concentration and concentration rate of CO2, output signal was the volume of fresh air change, designed a two-dimension fuzzy controller. Based on the search ...
w bile the United States has been investing in costly park-and-ride systems that have made transit increasingly dependent on the automobile, European and Japanese communities have been strengthening the potential for people to walk and bicycle to and from transit, boosting ridership at a far lower cost. In Japan and much of Europe, the fastest-growing and often predominant access mode to suburb...
Background & Aims: Air pollution can affect human health, plants, buildings and environment in many ways. Hence the aim of this study was determined to compare the air quality in six industrial cities (Tehran, Tabriz, Mashhad, Urmia, Ahvaz and Irak) by using air quality index (AQI) in 2011-2012. Materials & Methods: In order to AQI determination, hourly data of five criteria pollutants taken f...
