A cleaner doctor's kit: tiny bubbles mean huge improvements.
Introduction Nosocomial pneumonia is a major source of morbidity and mortality after severe burns. Burned patients suffer trace element deficiencies and depressed antioxidant and immune defences. This study aimed at determining the effect of trace element supplementation on nosocomial or intensive care unit (ICU)-acquired pneumonia. Methods Two consecutive, randomised, double-blinded, supplemen...
متن کاملTiny bubbles challenge giant turbines: Three Gorges puzzle.
Since the birth of the first prototype of the modern reaction turbine, cavitation as conjectured by Euler in 1754 always presents as a challenge. Following his theory, the evolution of modern reaction (Francis and Kaplan) turbines has been completed by adding the final piece of the element 'draft-tube' that enables turbines to explore water energy at efficiencies of almost 100%. However, during...
متن کاملAcoustic Measurements of Tiny Optically Active Bubbles in the Upper Ocean
In this project, which is closely linked to a separate project where the goal is to measure wave induced bubble clouds and their effect on radiance in the upper ocean (N000140710754), we intend to address the disturbing fact that despite the fundamental importance of optical backscatter in the ocean it is still not possible to explain more than 5 to 10 percent of the particulate backscattering ...
متن کاملTiny dancers
A vital step in growth factor-driven angiogenesis is the coordinated engagement of endothelial integrins with the extracellular matrix. The molecular mechanisms that partner growth factors and integrins are being elucidated, revealing an intricate interaction of surface receptors and their signaling pathways.
متن کاملTiny images
The human visual system is remarkably tolerant to degradations in image resolution: in a scene recognition task, human performance is similar whether 32 × 32 color images or multi-mega pixel images are used. With small images, even object recognition and segmentation is performed robustly by the visual system, despite the object being unrecognizable in isolation. Motivated by these observations...
