The rate and magnitude of buccal expansion are thought to determine the pattern of water flow and the change in buccal pressure during suction feeding. Feeding events that generate higher flow rates should induce stronger suction pressure and allow predators to draw prey from further away. We tested these expectations by measuring the effects of prey capture kinematics on suction pressure and t...

Suction feeding is central to prey capture in the vast majority of ray-finned fishes and has been well studied from a detailed, mechanistic perspective. Several major trade-offs are thought to have shaped the diversification of suction-feeding morphology and behavior, and have become well established in the literature. We revisited several of these expectations in a study of prey capture morpho...

Hydraulic collecting and pipe transportation are regarded as an efficient way for exploiting submarine mineral resources such the manganese nodules ores. Coarse particles on surface of sea bed sucked by a during mining crushing mineral. In this paper, critical suction velocity lifting coarse is investigated through series laboratory experiments, solid–liquid two-phase flow characteristics obtai...

OBJECTIVES This study attempted to identify which is the more effective suction system. The objective was to compare open versus closed suction systems according to a systematic review. METHODS A search of scientific literature was conducted in MedLine, LILACS and Cochrane between 1997 and August 2007 using the key words: endotracheal suction and closed suction. Included were articles that co...

Critically ill patients are intubated or tracheostomized because, in most cases, these individuals require invasive mechanical ventilation. The cannulae that are used include the cuff, which can act as a reservoir for oropharyngeal secretions, predisposing to ventilator-associated pneumonia. Studies have revealed that the suction of subglottic secretions through the dorsal suction lumen above t...

The effect of base suction on a plane wake was found to produce significant changes on wake dynamics. The wake is produced by merging two boundary layers from the trailing edge of a splitter plate in a two stream water tunnel. A threshold suction speed exists which is equal to half of the free stream velocity. If the suction speed is below the threshold, the wake flow is unstable. If the suctio...

OBJECTIVES To determine the efficacy of 400 mcg sublingual misoprost as an adjunct to suction evacuation in first trimester pregnancy termination. METHOD(S) During the study period of January2006-June 2007, two hundred twenty-one pregnant women wanting first trimester pregnancy termination were randomised into two groups. In the study group of one hundred twenty-one women, sublingual misopros...
