Evaluation of the contamination of stethoscopes used in pediatric units of a hospital and emergency service showed that 87% of them presented contaminated diaphragms. Coagulase-negative Staphylococcus was the microorganism most frequently isolated. The resistance to antibiotics indicates that stethoscopes should be considered to be an important vehicle for disseminating bacteria resistant to an...

The performance of systems involving a body in a fluid flow can be enhanced by manipulation of the body shape through flow control. Active flow control, the focus of this work, is achieved by energizing low-momentum regions at the wall by tangential blowing using air. One mechanism for blowing air into this region is through synthetic jets. They are devices that push air out from a fixed orific...

Two patients with intestinal submucosal diaphragm disease associated with non-steroidal anti-inflammatory drugs are presented. The jejunum was affected in one, and in the other the ascending colon. Most previously reported cases have shown ileal disease and no case to date has shown involvement of the colon. The reasons for the localisation of these diaphragms remain unclear.

There is growing debate as to the primal role of capillary endothelial cells in the barrier function of the glomerular filter. Two experts argue the points for and against. Clearly unresolved is agreement whether glomerular capillary endothelium has fenestrae subtended by diaphragms.

Abstract A growing attention has been paid to the deep renovation of RC buildings, particularly focusing on their structural vulnerability and development retrofit strategies; however, issue in-plane diaphragm action capacity existing floors rarely addressed. Although floor does not seem critical for seismic structures, commonly affected by greater vulnerabilities, it may become when an additio...
