For many decades, ventilated cavities in wall assemblies of buildings have been essential for creating moisture resilient constructions by allowing airflow within the air gap to promote drying. In addition that, cavity can enhance thermal performance building envelope, depending on change rate and outdoor conditions. Therefore, effective factors behind common with external cladding are specifie...

This paper investigates the thermal performance and energy-saving potential of sunspace an old apartment building in Qingdao through experiments software simulations. study found that different modes user behavior can have a substantial impact on studied winter. The bedroom with non-ventilated showed higher average temperature than without sunspace. However, had more heat loss when was naturall...

AIM To investigate the changes in the venoarterial carbon-dioxide gradient (V-a Pco(2)) and its prognostic value for survival of patients with severe sepsis and septic shock. METHODS The study was conducted in General Hospital Holy Spirit from January 2004 to December 2007 and included 71 conveniently sampled adult patients (25 women and 46 men), who fulfilled the severe sepsis and septic sho...

Caring for patients who are mechanically ventilated poses many challenges for critical care nurses. It is important to humidify the patient's airways artificially to prevent complications such as ventilator-associated pneumonia. There is no gold standard to determine which type of humidification is best for patients who are artificially ventilated. This article provides an overview of commonly ...

Background and purpose: Elevated CO2 rate in a building affect the health of occupant. This document presents results of an experimental analysis conducted in 50 offices located in 12 buildings with different layer in Cameroon (Yaounde). This study took place in 2012, during the dry and the rainy seasons. The main goal is to show the influence of the building structure, the ventilation and the ...

This paper reports the results of a numerical analysis of the influence of various parameters for the combined free and forced convection problem in a vented cavity with a centered heat generating element. Forced convection flow conditions are imposed by providing an inlet at the bottom of the left vertical wall and an outlet opening at the top of the opposite sidewall. Numerical solutions of t...
