A HIGH KITE ASCENSION AT BLUE HILL

Eliminating facility-acquired pressure ulcers at Ascension Health.

BACKGROUND In 2004, as part of Ascension Health's "Healthcare That Is Safe" initiative, St. Vincent's Medical Center, as an alpha site, was charged with defining best practices to eliminate facility-acquired pressure ulcers. A comprehensive plan, including the "SKIN" (Surfaces, Keep the patients turning, Incontinence management, Nutrition) bundle, was developed. RESULTS The incidence of press...

A Comparison of GPS Performance in a Scintillation Environment at Ascension Island

Post-sunset disturbances in the equatorial ionosphere routinely cause rapid phase and amplitude fluctuations (i.e., scintillation) of radio waves propagating through the disturbed regions. The intensity of scintillations is positively correlated with the solar cycle and the associated signal fades will often exceed 20 dB at L-band frequencies during solar maximum. The effect of such an environm...

‘You’re a kite dancing in a hurricane,

What would it mean to describe James Bond as a man in his element? As an expression in English, being “in one’s element” usually refers to someone or something well suited to what they are doing. The term often conveys, when a human actor is involved, a sense of comfort, enjoyment, and even pleasure. Conversely, when we note that someone or something is “out of their element”, we highlight othe...

The Symplectic Penrose Kite

The purpose of this article is to view the Penrose kite from the perspective of symplectic geometry. Mathematics Subject Classification 2000. Primary: 53D20 Secondary: 52C23 Introduction The kite in a Penrose aperiodic tiling by kite and darts [8, 9] is an example of a simple convex polytope. By the Atiyah, Guillemin–Sternberg convexity theorem [1, 6], convex polytopes that are rational can be ...
