Loss of buoyancy control in the copepod .

A mechanism is demonstrated that could explain large-scale aggregations of lipid-rich copepods in the surface waters of marine environments. Laboratory experiments establish that changes in salinity and temperature induce lipid-mediated buoyancy instability that entrains copepods in surface waters. Reduced hydrostatic pressure associated with forced ascent of copepods at fjordic sills, shelf breaks and seamounts would also reduce the density of the lipid reserves, forcing copepods and particularly those in diapause to the surface.

Reducing avoidable deaths from failure to rescue: a discussion paper.

Aim: This article proposes a radical new approach to the monitoring and governance of services, and the education and training of nurses to meet 'failure to rescue' requirements.

Background: Healthcare policy in the UK that seeks to ensure safe and effective services for the acutely ill has largely failed, resulting in adult patients dying unnecessarily. Despite grand rhetoric, UK governments have distanced themselves from implementation, resulting in patchy localised developments and creating inconsistent service responses.

Patient safety in acute care: are we going around in circles?

This article provides a critical discussion examining why adult patients continue to unnecessarily deteriorate and die despite repeated healthcare policy initiatives. After considering the policy background and reviewing current trends in the data, it proposes some solutions that, if enacted, would, the authors believe, have a direct impact on survival rates. Health professionals working in hospitals are failing to recognise signs of physiological deterioration.

Probability of spacesuit-induced fingernail trauma is associated with hand circumference.

Unlabelled: A significant number of astronauts sustain hand injuries during extravehicular activity training and operations. These hand injuries have been known to cause fingernail delamination (onycholysis) that requires medical intervention. This study investigated correlations between the anthropometrics of the hand and susceptibility to injury.

Compression under a mechanical counter pressure space suit glove.

Background: Current gas-pressurized space suits are bulky stiff shells severely limiting astronaut function and capability. A mechanical counter pressure (MCP) space suit in the form of a tight elastic garment could dramatically improve extravehicular activity (EVA) dexterity, but also be advantageous in safety, cost, mass and volume. The purpose of this study was to verify that a prototype MCP glove exerts the design compression of 200 mmHg, a pressure similar to the current NASA EVA suit.

Skin microvascular flow during hypobaric exposure with and without a mechanical counter-pressure space suit glove.

Introduction: Current space suits are rigid, gas-pressurized shells that protect astronauts from the vacuum of space. A tight elastic garment or mechanical-counter-pressure (MCP) suit generates pressure by compression and may have several advantages over current space suit technology. In this study, we investigated local microcirculatory effects produced with and without a prototype MCP glove.
