Patients who are critically ill and receiving invasivemechanical ventilation are at increased risk for accumula-tion of secretions in the lower airways. Such accumula-tion of airway mucus can induce atelectasis and contributeto ventilator-associated pneumonia. Preventive airwaycare interventions, including …

The European common cuttlefish (Sepia officinalis) makes use of undulatory locomotion through its lateral fins. This type of locomotion shows good potential for application for underwater vehicle thrust because it gives the user advantages like maneuverability, stable station keeping, and energy efficiency. …

Extrudate swell simulations and experiments have been performed with a viscoelastic tire rubber compound at high flow rates through a circular die. A 3-mode PTT model was fitted onto rheological data of the rubber. The PTT model covers the range of shear rates present in the simulation. Convergence of …
