A Randomized Trial of Intensive versus Standard Blood-Pressure Control.
New England Journal of Medicine, 2017 To the Editor: Wright et al. (Nov. 26 issue)1 report on the Systolic Blood Pressure Intervention Trial (SPRINT). By focusing on blood-pressure levels, rather than on specific antihypertensive agents, this trial follows a rich heritage of government ...

Vibrating Cantilever Transducer Incorporated in Dual Diaphragms Structure for Sensing Differential Pneumatic Pressure [PDF]
International Journal on Soft Computing ( IJSC ) Vol.2, No.4,
November 2011, 95-109, 2012 Pneumatic pressure cells with thin metallic spherical diaphragm of shallow spherical shell configuration linked with vibrating wire pickup or vibrating cantilever pickup were reported in the past. In order to enhance the sensitivity of the pressure cell this work considers dual diaphragm structure fitted with cantilever pickup.

Driving pressure and survival in the acute respiratory distress syndrome.
New England Journal of Medicine, 2015 BACKGROUND Mechanical-ventilation strategies that use lower end-inspiratory (plateau) airway pressures, lower tidal volumes (VT), and higher positive end-expiratory pressures (PEEPs) can improve survival in patients with the acute respiratory distress ...

Pressure-induced volumetric negative thermal expansion in CoZr2 superconductor [PDF]
, 2023 We investigate the thermal expansion and superconducting properties of a CuAl2-type (tetragonal) superconductor CoZr2 under high pressures. We perform high-pressure synchrotron X-ray diffraction in a pressure range of 2.9 GPa < P < 10.4 GPa and discover that CoZr2 exhibits volumetric negative thermal expansion under high pressures.

Political pressure deflection [PDF]
Public Choice, 2004 Much economic policy is deliberately shifted away from direct political processes to administrative processes—political pressure deflection. Pressure deflection poses a puzzle to standard political economy models which suggest that having policies to ‘sell’ is valuable to politicians.

Pressure-Induced Polymerization: Addition and Condensation Reactions
Molecules, 2021 Under pressure of 1–100 GPa, unsaturated organic molecules tend to form covalent bond to each other for a negative enthalpy change, which often produces polymeric materials with extended carbon skeleton.

Pore Water Pressure in Sand Bed under Oscillating Water Pressure [PDF]
, 1984 In this paper the theoretical method to analyse the pore water pressures in the sand bed under the oscillating water pressure is developed. In the former researchs the validity of the theoretical treatment for the one-dimensional problem has been ...

Successive phase transitions under high pressure in FeTe0.92 [PDF]
J. Phys. Soc. Jpn. 78 (2009) 083709., 2009 We performed magnetization and electrical resistivity measurements under high pressures of up to 19 GPa for FeTe0.92. The compound shows an anomaly in magnetization and resistivity at atmospheric pressure due to a structural distortion accompanied by a magnetic transition.

In situ high-pressure spectroscopic studies using moissanite (4H-SiC) anvils
AIP Advances, 2018 We examined the Raman scattering and IR absorption spectroscopy of 4H-SiC and its performance as an anvil material for high-pressure UV-visible absorption spectroscopic measurements.
