Bioinspired engineering based on biosonar systems in nature is reviewed and discussed in terms of the merits of different approaches and their results: biosonar systems are attractive technological paragons because of their capabilities, built-in task-specific knowledge, intelligent system integration and diversity. Insights from the diverse set of sensing tasks solved by bats are relevant to a...

Ventricular dysfunction, elevated pulmonary vascular resistance, and residual distal pulmonary artery distortion contribute to early mortality after a Fontan operation; they may be transient or reversible. A baffle fenestration, allowing right-to-left shunting, maintains cardiac output and limits right atrial pressure. A baffle fenestration was surgically created at the time of a modified Fonta...

One hundred and twenty patients with transposition of the great arteries (TGA) were encountered over a decade. Survivors have been followed until after definitive repair, and 39% were alive when reviewed. The majority (69%) had no significant communication between the pulmonary and systemic circulations. Of 48 patients in this poor-mixing group who had an atrial septectomy, 23 (48%) survived to...

OBJECTIVE To assess long term outcome of patients who underwent Mustard or Senning repair for transposition of the great arteries up to 30 years earlier. DESIGN Retrospective review of medical records. SETTING The six university hospitals in Belgium with paediatric cardiology departments. PATIENTS 339 patients were reviewed, of whom 124 underwent the Mustard procedure and 215 the Senning ...

Background. Improvement of the methodology for computational analysis residual stresses in structural elements reactor is an integral part work when extending service life NPP power units.
 Objective. Determine value technological stress arising baffle a VVER-1000 during welding and postweld heat treatment according to austenitizing mode. To evaluate effect considering dependence transfer ...

A three-dimensional computational study of double-diffusive natural convection was conducted to explore the impact tilt on thermal and solutal performance a floating pyramidal solar still filled with an air-steam mixture. In present work, is cooled from upper walls maintained at low vapor concentration. The bottom wall hot temperature high Four different models baffles placed in region have bee...

In this paper, a nanofluid-based solar collector duct equipped with baffles is examined numerically. Baffles are located on the back plate to guide nanofluid flow toward absorber for heat transfer enhancement purposes. Cu-water fixed rate and concentration in baffled investigated thermohydraulic mechanisms. different inclination angles, heights pitches considered study. Numerical simulations pe...

OBJECTIVE To assess the impact of the bidirectional cavopulmonary shunt, total cavopulmonary connection, and baffle fenestration on outcome of the Fontan operation in our unit. METHOD We reviewed 123 bidirectional cavopulmonary shunts and 264 Fontan operations performed from 1980 to 1995. Analysis of pulmonary artery size (right and left main and lower lobe branches) before and after bidirect...
