An ionised/non-ionised dual porosity model of intervertebral disc tissue.
The volume of the intrafibrillar water space--i.e. the water contained inside the collagen fibres--is a key parameter that is relevant to concepts of connective tissue structure and function. Confined compression and swelling experiments on annulus fibrosus samples are interpreted in terms of a dual porosity model that distinguishes between a non-ionised intrafibrillar porosity and an ionised e...
متن کاملIonised carbon and galaxy activity
We investigate the possibility that the decrease in the relative luminosity of the 158 μm [C ii] line with the far-infrared luminosity in extragalactic sources is due to a larger contribution from the heated dust emission in the more distant sources. Due to the flux limited nature of these surveys, the luminosity of the detected objects increases with distance. However, the fact that the [C ii]...
متن کاملThe Sombrero galaxy ⋆ III . Ionised
We present the results of new 3D TIGER spectroscopic observations and archived HST/WFPC2 and NICMOS images of the central region of M 104. The [N ii]+Hα images reveal the presence of a nuclear spiral structure, and the gaseous kinematics in the central arc-second shows evidence for kinematical decoupling of the central peak. A straight nuclear dust lane, with a weak symmetric counterpart, is se...
متن کاملMeasurement of ionised calcium concentration in neonates.
Whole blood ionised calcium concentration was measured simultaneously in capillary and arterial blood from neonates being nursed on an intensive care unit using an ion selective electrode. The mean arterio-capillary difference was -0.027 mmol/l (95% confidence intervals -0.041 to -0.012 mmol/l) and the limits of agreement between the two measurements were 0.034 and -0.088 mmol/l. Measurement of...
متن کاملSerum ionised calcium concentration: measurement versus calculation.
Four hundred and eighteen measurements of serum ionised calcium, total calcium, and protein concentrations were made from 47 normal volunteers, 104 patients with chronic renal failure (33 being treated conservatively and 71 with regular haemodialysis), and 83 renal transplant recipients. The serum ionised calcium concentration was measured with an Orion SS-20 meter and calculated from the total...
