This paper explores the method of assessing regional spatial ventilation performance for the design of residential building arrangements at an operational level. Three ventilation efficiency (VE) indices, Net Escape Velocity (NEV), Visitation Frequency (VF) and spatial-mean Velocity Magnitude (VM), are adopted to quantify the influence of design variation on VE within different regional spaces....

Tracheobronchial disruption is an uncommon but severe complication of double lumen endotracheal tube placement. The physical properties of a double lumen tube (large external diameter and length) make tracheobronchial injury more common than that associated with smaller single lumen endotracheal tubes. Here we present the case of an iatrogenic left main bronchus injury caused by placement of a ...

In a prospective study of 13 patients requiring pneumonectomy for unilateral post-tuberculous lung destruction the left side was found to be affected in 12. Review of a further 172 cases showed the left lung to have been destroyed in 109 (63%). It is suggested that this predominance of the left side is due to the anatomical characteristics of the left main bronchus and that disordered haemodyna...

Emergency Department, complaining of exertional dyspnea. A review of his medical history revealed that 3 years earlier he had tried to swallow a knife. It was removed from the esophagus by endoscopy. Two years before admission he told his relatives that he had swallowed another knife, but they did not believe him. Posteroanterior (Fig. 1) and lateral (Fig. 2) views of the chest were obtained, d...

seismic performance and loss assessment studies for stock of buildings are generally based on representative models due to extremely large number of vulnerable buildings. the main problem is the proper reflection of the building stock characteristics well enough by limited number of representative models. this study aims to provide statistical information of structural parameters of turkish bui...

results significantly high levels of radon gas were found mostly in water and residential buildings. conclusions it conclusion with regard to the study of building materials, granite stone and adobe coverings cannot be recommended for construction purposes. materials and methods the most important route of exposure to such radiation is indoor places. in this investigation measurement of radon i...

Eighty attempts at placing suction catheters in the left main bronchus were analysed by studying chest radiographs. When angled catheters were used via a tracheostomy tube the success rate was 75%; the rate fell to 15% when straight tubes were used through an orotracheal tube. Assessment and control of the tube length was found to be important to avoid kinking and subsequent obstruction of the ...
