Turbidity currents in the ocean and lakes are driven by suspended sediment. The vertical profiles of velocity and excess density are shaped by interaction between the current and bed as well as between the current and the ambient water. This paper presents 48 series of experiments in which saline gravity currents flow through a laboratory sinuous flume. flume contains three successive bends wit...

BACKGROUND Advances in paediatric critical care have resulted in increased survival of critically ill patients, many of whom require long-term ventilation as a means of life support. AIM To determine current trends in resource utilization, and problems in the care of acute and chronic paediatric intensive care patients. DESIGN Open observational study. METHODS We evaluated consecutive adm...

introduction: the bed nucleus stria terminalis (bst) is a part of the limbic system. it was recently shown that chemical stimulation of the bst by l-glutamate elicited cardiovascular depressive responses. in the present study, we have investigated the possible cardiovascular role of the gabaergic receptors in bst by microinjection of its agonist and antagonists. methods: experiments were perfor...

Since enactment of the 1990 amendments to the Clean Air Act, the control and removal of volatile organic compounds (VOCs) from contaminated air streams have become a major public concern (1). Consequently, considerable interest has evolved in developing more economical technologies for cleaning contaminated air streams, especially dilute air streams. Biofiltration has emerged as a practical air...
