The capillary filtration coefficient was measured in human extremities by a simplified technique using the capacitance plethysmograph. The method was validated in terms of consistency of values obtained on the same individual at various times, the correspondence between values obtained on a group of normal persons, and the agreement between values reported here and those of earlier workers made...

A modified model for predicting the friction force between drill-string and borehole wall under in-plane vibrations was developed. It was found that the frictional coefficient in sliding direction decreased significantly after applying in-plane vibration on the bottom specimen. The friction reduction is due to the direction change of friction force, elastic deformation of surface asperities and...

Self-diffusion coefficient tensors of a reentrant liquid crystal CBOBP were measured in the high and low temperature SA phases. In the high temperature SA phase, the diffusion coefficient component D// is larger than D⊥. The two activation energies are similar. This property resembles that of the nematic phase, and indicates that the layer structure of the high temperature SA phase is disordere...

Risk management is about reducing the likelihood of errors. Its particular aims are to reduce errors that are costly in terms of damage, discomfort, disability, or distress to an individual and to limit financial loss to an organisation. Risk management achieves this through detecting, reporting, and correcting actual or potential deficiencies in the process of care that, however small, could l...

Colquhoun, W. P., and Edwards, R. S. (1970). Brit. J. industr. Med., 27, 266-272. Circadian rhythms of body temperature in shift-workers at a coalface. The oral temperatures of a group of coalface workers were recorded daily at intervals during their period ofwork underground, over a three-week cycle of day, afternoon and night shifts. The basic mean circadian rhythm of temperature observed in ...

BACKGROUND There is no standard method of measuring change in chronic pain severity. Clinical trials commonly use serial assessment scales, completed at two points in time, to estimate change in pain severity, while clinicians usually ask patients to make a retrospective assessment of change. How the two methods compare is not known. AIM To assess different methods of measuring change in chro...

The diffusion coefficients of Na(+), Rb(+), and cl(-) were determined in lecithin-water lamellar phases at 18 degrees C as a function of phase hydration. Diffusion was measured within the phase with no transfer between phase and bulk aqueous medium. The relative diffusion coefficients of anion and cation depended strongly on phase hydration. At low water content, the diffusion coefficient of Cl...

the growing population and increasing socio-economic necessitiescreates a pressure on land use/land cover. nowadays, land use change detection using remote sensing data provides quantitative and timely information for management and evaluation of natural resources. this study investigates the land use changes in part of hableh rood watershed of iran using landsat 7 and 8 (sensor etm+ and oli) i...
