Implementation and Mixed-Methods Assessment of an Early Mobility Interprofessional Education Simulation.

Introduction: Extended periods of bed rest and mechanical ventilation (MV) have devastating effects on the body.

Background: Early mobility (EM) for patients in respiratory failure is safe and feasible, and an interprofessional team is recommended. Using simulation to train EM skills improves student confidence.

Cycle-to-cycle flow variations in a square duct with a symmetrically oscillating constriction.

Spatially and temporally resolved Digital Particle Image Velocimetry (DPIV) measurements are presented of flow complexities in a nominally two-dimensional, symmetric, duct with an oscillating constriction. The motivation for this research lies in advancing the state-of-the-art in applying integral control volume analysis to modeling unsteady internal flows. The specific target is acoustic modeling of human phonation.

Observations of Shear Stress Effects on Staphylococcus aureus Biofilm Formation.

bacteria form biofilms and distinctive microcolony or "tower" structures that facilitate their ability to tolerate antibiotic treatment and to spread within the human body. The formation of microcolonies, which break off, get carried downstream, and serve to initiate biofilms in other parts of the body, is of particular interest here. It is known that flow conditions play a role in the development, dispersion, and propagation of biofilms in general.
