Oesophageal (oes) and central venous pressure (CVP) were compared as indices of transpulmonary pressure change (deltap). The mean increase of deltaPoes over deltapCVP was 2.8 cm H2O. The size and variability of the increase were similar to the expected difference between oesophageal and pleural pressure fluctuations occurring in the supine patient. Central venous pressure may be more accurate a...

OBJECTIVE To investigate the possible causes of abnormal blood pressure control in light chain related (primary, AL) amyloidosis. DESIGN Cardiovascular, autonomic, and respiratory response to passive tilting were investigated in 51 patients with primary amyloidosis (mean (SEM) age 56 (2) years) and in 20 age matched controls. Spontaneous fluctuations in RR interval, respiration, end tidal car...

Data are presented of experiments with turbulent open channel flow over rough surfaces and large relative submergence, which are conducted in two series with different geometric boundary conditions. During the experiments an oscillating fluid motion in the uppermost filter layer is visualised by the injection of a tracer dye. It is shown that this oscillating fluid motion is driven by highly un...

The energy performance and pressure fluctuations in a centrifugal pump with inlet guide vanes (IGVs) are investigated experimentally and numerically in a prewhirl angle range of −24◦ to 24◦ and in an axial distance range of 280 mm, 380 mm, and 460 mm. The reliability and accuracy of the numerical method are validated by the satisfactory agreement between the experimental data and numerical resu...

We present the study of a magnetic quantum phase transition in the itinerant-electron ferromagnet Ni3Al at high pressures. Electrical resistivity measurements in a diamond anvil cell at hydrostatic pressures up to 100 kbar and temperatures as low as 50 mK indicate that the Curie temperature collapses towards absolute zero at a critical pressure pc close to 80 kbar. Over wide ranges in pressure ...
