متن کاملQualitative Modelling of the Natural Ventilation Potential in Urban Context
The two objectives of natural ventilation in buildings are the improvement of indoor air quality and thermal comfort. The methodology proposed hereafter provides an assessment of the natural ventilation potential for indoor air quality, while taking into consideration the other objective. More precisely, requirements on comfort impose the appropriate ventilation strategies to be applied for eac...

متن کاملA simple method for designation of urban ventilation corridors and its application to urban heat island analysis
This paper describes urban wind ventilation mapping, using the concept of “building frontal area index”, and uses the Kowloon peninsula of Hong Kong as an example of a dense, sub-tropical urban environment where ventilation is critical for human health. The frontal area index is calculated for uniform 100 m grid cells, based on three dimensional buildings in each cell, for eight different wind ...
متن کاملComparison of the effect of pressure support ventilation and volume assured pressure support ventilation on weaning patients off mechanical ventilation after cardiac surgery
Background: Weaning from mechanical ventilation in the intensive care unit is an important step in the treatment process. More patients in less than 6 hours after cardiac surgery can be separated from mechanical ventilation and extubated. However, 20-40% of patients after cardiac surgery, due to dysfunctional ventilator weaning response (DVWR), still remain under mechanical ventilation. Therefo...
