BACKGROUND AND PURPOSE Hemodynamics of cerebral vasospasm after subarachnoid hemorrhage remain unclear, and the discrepancy between ultrasonographic or angiographic evidence of arterial narrowing and neurological ischemic deficit is still debated. Most blood flow studies have been involved with large arteries, and thus, very little is known regarding the hemodynamic behavior of small perforatin...

Methicillin-resistant Staphylococcus aureus (MRSA) has emerged as an important pathogen. Successful detection starts with the selection of an appropriate specimen collection device. The Copan ESwab, a new swab, was compared with a commonly used Copan Venturi swab for the recovery of MRSA. In vitro assessment was performed according to the Clinical and Laboratory Standards Institute (CLSI) M40-A...

The necessity for dissolved oxygen in water is crucial the survival and growth of aquatic organisms, particularly tilapia. Seventy-five percent tilapia will die if there insufficient water. This work seeks to develop a venturi bubble-generating technique combat scarcity A floating pump with capacity 12 m<sup>3</sup>/hour was selected as medium distributing generating vacuum pressure...

long-throated flumes are measurement structures often used in water and wastewater systems to determine the flow discharge. the head-discharge relationship of long-throated flumes is traditionally determined following the critical flow theory and the boundary layer concept. after a review of the traditional approach and an analysis of the approximate assumptions of the boundary layer approach, ...

RESUMO O objetivo deste trabalho foi avaliar o potencial do Venturi para a síntese de biodiesel partir óleo comestível residual em rota metílica. Para tanto, construído escala laboratório um aparato experimental constituído tanque 5,2 L e dispositivo projetado produzir fenômeno cavitação. A produção avaliada três diferentes pressões entrada Venturi: 4,4; 2,9; 1,4 bar. Os teores ésteres metílico...
