this work reports the results of the application of the second-order maccormack method for numerical solution of‎ the conservative form of two-dimensional non-hydrostatic and fully compressible navier-stokes equations governing an inviscid and adiabatic atmosphere‎. various aspects of the computational approach such as discretization of the governing equations for the interior and boundary poin...

Membrane retrieval following exocytosis in synaptic terminals is fast and compensatory, however, little is known about the factors that regulate or contribute to this special form of endocytosis. We used whole-terminal capacitance measurements to examine the effect of hydrostatic pressure on compensatory endocytosis in single synaptic terminals of retinal bipolar neurons. We report that a small...

Changes in hydrostatic pressure, at levels as low as 10 mm Hg, have been reported in some studies to alter cell function in vitro; however, other studies have found no detectable changes using similar methodologies. We here investigate the hypothesis that the rate of depressurization, rather than elevated hydrostatic pressure itself, may be responsible for these reported changes. Hydrostatic pr...

To determine whether beta-adrenergic agonist therapy increases alveolar liquid clearance during the resolution phase of hydrostatic pulmonary edema, we studied alveolar and lung liquid clearance in two animal models of hydrostatic pulmonary edema. Hydrostatic pulmonary edema was induced in sheep by acutely elevating left atrial pressure to 25 cmH(2)O and instilling 6 ml/kg body wt isotonic 5% a...

background loss of motion is a well-known complication after elbow trauma and in severe cases, arthrolysis of elbow is the procedure of choice. the posterior approach might have some advantages especially in post-traumatic patients who have undergone the same surgical approach in the past. objectives the aim of this study was to evaluate the short-term outcomes of elbow arthrolysis through post...

[1] Corrections to zenith atmospheric delays (including hydrostatic components) are estimated in geodetic analyses using partial derivatives that relate wet delays to the phase observations. At low-elevation angles, partial derivatives of the hydrostatic and wet delays are sufficiently different as to cause errors in the estimates of station heights and zenith total delays unless accurate surfa...

Spiral X-ray Computed Tomography (SXCT), Optical Surface Scanning (OSS), and hydrostatic weighing methods were used to measure stump volume of trans-tibial amputees. The precision and accuracy of these methods were assessed in a validation study. A repeated measures analysis of variance statistical design was employed that required each participant to be measured (scanned) twice at each of two ...

Previous studies have shown that the elevation of renal interstitial hydrostatic pressure by the direct expansion of renal interstitial volume increases urinary sodium excretion. The objective of the present study was to investigate whether proximal tubules respond to the elevated renal interstitial hydrostatic pressure and whether the inhibition of prostaglandin synthesis would alter the effec...

Measurement of body composition is an important part of any assessment of health or fitness. Hydrostatic weighing is generally accepted as the most reliable method for the measurement of body fat content, but is inconvenient. Electrical impedance analysers have recently been proposed as an alternative to the measurement of skinfold thickness. Both these latter methods are convenient, but give v...

Objective: Lower extremity stiffness is associated with variables such as the frequency and length of running steps, the amount of muscle force and power production. Previous studies showed contradictory findings regarding the relationship between lower extremities joints stiffness and start velocity. Sprint start can be highly affected by two key components of lower limb stiffness, namely, for...
