Moreover, it has been found that the difference in the bed performance evaluated due to the absence of axial heat conduction in the bed is notably decreasing with the decrease in the number of transfer units of heat or mass.
When the flow resistance within the bottom inlet zone is larger than that within the upper zone, for example, on account of the difference in the bed porosity or the geometry of the bed elements, the effects of the bottom zone increase.
Furthermore, the finding of distinct topographic variations in the development of arterial occlusive disease in spite of uniform systemic risk factors (sex, cholestorol, triglyceride levels, smoking, hypertension) was thought to indicate genetic differences in the arterial bed (DeBakey and Glaeser, 2000).
It has also been shown that measurements of vascular reactivity vary between different assessment methods (35), likely because of differences in the vascular beds being assessed, which may further explain the differential findings between this and previous studies of microvascular reactivity.
We have previously shown that DR may be associated with retinal endothelial dysfunction in the same cohort (3) and that this may be due to differences in the vascular beds.
First of all, waste ion exchange resins were separated into cationic and anionic resins by a specific gravity difference in the fluidized bed.
There was no difference in the electric bed group for all physiological parameters.
While the direction of effect may be consistent across settings, variations in the magnitude of effect may be affected by factors such as differences in ICU bed capacity, the profile of patients served, organisational procedures and standards, as well as physician characteristics.
There was no significant difference in the average bed-days fuzzy set membership between slightly high risk and very high risk POs (0.631 and 0.559, respectively; one-tailed t-test p = 0.3446), nor were bed-days significantly correlated with DxCG score (r = 0.314; one-tailed t-test p = 0.14).
The bars indicate the standard deviation of the fluctuation (the length of each bar is 2σ), which is obtained from data sampled every 500 steps from 1 × 105 to 5 × 105 steps for 10 runs under the same conditions (except for small random differences in the initially almost flat bed).
