Decay of the Kinetic and the Thermal Energy of Compressible Micropolar Fluids. We consider a heat conducting compressible micropolar fluid at rest and filling a closed stationary rigid container. We show that tim energy of arbitrary disturbances of the fluid eventually decays. Abnahme der kinetischcn und der thermischen Energie kompressibler mikropolarcr Fliissigkeiten. Betrachtet wird eine ruh...

Timing and duration of ore deposit formation are crucial to understanding the mineralization process. To address this, geochronological (U-Th)/He method, geochemical H- O-isotope compositions pure goethite formed in Imini karst-hosted Mn district (High Atlas, Morocco) were examined detail. Two main generations cavity-filling fracture-filling identified, both precipitated prior massive oxide ore...

BACKGROUND Mathematical coupling may explain in part why cardiac filling volumes obtained by transpulmonary thermodilution may better predict and monitor responses of cardiac output to fluid loading than pressures obtained by pulmonary artery catheters (PACs). METHODS Eleven consecutive patients with hypovolaemia after coronary surgery and a PAC, allowing central venous pressure (CVP) and con...

BACKGROUND AND PURPOSE Cerebral blood flow (CBF) is reduced after subarachnoid hemorrhage (SAH), and symptomatic vasospasm is a major cause of morbidity and mortality. Volume expansion has been reported to increase CBF after SAH, but CBF values in hypervolemic (HV) and normovolemic (NV) subjects have never been directly compared. METHODS On the day after aneurysm clipping, we randomly assigne...

OBJECTIVE To investigate the pathophysiological (cardiac function and physical performance) significance of clinically silent interstitial lung water accumulation in patients with moderate heart failure; to use isolated ultrafiltration as a means of extravascular fluid reabsorption. DESIGN Echocardiographic, Doppler, chest x-ray evaluations, and cardiopulmonary tests at baseline, soon after u...

BACKGROUND The control of extracellular volume is a key parameter for reducing hypertension and the incidence of cardiovascular mortality in dialysis patients. In recent years bioimpedance measurement (BIA) has been proven as a non-invasive and accurate method for measuring intracellular and extracellular fluid spaces in man. In addition, plasma atrial natriuretic peptide (ANP) and cyclic guano...

In our study of the aging phenomena in silica suspensions we immersed precipitated silica particles in methyl-terminated PDMS (silicone oil), mineral oil, and glycerol/water and measured their viscoelastic properties as a function of time. We found that the samples based on silicone oil, initially of a pasty consistence, became fluid-like after a period of about three weeks. Aqueous samples age...

Objective: Adenosine 5'-triphosphate (ATP) is released from the bladder mucosa during bladder filling and is assumed to stimulate sensory neurons in the lamina propria and to regulate the apical delivery of fusiform vesicles in urothelial umbrella cells. As a parasympathetic cotransmitter, ATP contracts the detrusor smooth muscle. Therefore, extracellular ATP likely regulates the two phases of ...
