Pressure off
The value of creating marine reserves to protect ecosystems from over-exploitation or destruction is becoming increasingly clear, although still often resisted by fishing and other interests. So the results of a new survey of the wildlife around two protected areas of Scotland's most famous sea lochs, which have been catalogued in detail for the first time in two new reports by Scottish Nationa...
متن کاملHypertension: Taking the Pressure Off
“My eighty-three year old mother called me last week, ‘Brenda!’ her voice sounded alarmed, ‘I just took my blood pressure and I am worried, it is 160/100’” Brenda, was worried too, but knew something about blood pressure. “Mom, just sit down, drink 3 big glasses of water, and I’ll be over in about 45 minutes and we’ll take your blood pressure again.” Arriving 45 minutes later, Brenda retook mom...
متن کاملPhlebotomy in the community takes pressure off hospitals.
The Unison survey, Running on Empty – NHS Staff Stretched to the Limit, reveals a health service under intolerable strain (Editorial and News April 16). Sixty-five per cent of respondents say they do not have enough time to spend with patients and 55 per cent report that, as a result, care is left undone. This is despite the fact that half of the respondents work through their breaks or beyond ...
متن کاملA capacitive absolute-pressure sensor with external pick-off electrodes
This paper describes a capacitive absolute-pressure sensor in which the sealed lead transfer is eliminated. The pick-off capacitance is between a flap or skirt-like extension of the flexible diaphragm that reaches past the sealed cavity, and an electrode patterned on the substrate directly below this extension. The sidewall of the cavity is relatively narrow and flexible. Finite-element analysi...
متن کاملVoltage-addressable on/off microvalves for high-pressure microchip separations.
We present a microchip-based, voltage-addressable on/off valve architecture that is fundamentally consistent with the pressures and solvents employed for high-pressure liquid chromatography. Laser photopatterning of polymer monoliths inside glass microchannels is used to fabricate mobile fluid control elements, which are opened and closed by electrokinetic pressures. The glass substrates and cr...
