Background: Thirst and dry mouth are common among hemodialysis (HD) patients. This paper reports a study to evaluate the impact of an acupressure program on HD patients’ thirst and salivary flow rates. Methods: The acupressure program included placebo, followed by true acupressure each applied for 4 weeks. Twenty-eight patients (mean age 57.6, SD = 16.13 years) first received a sticker as place...

J. Węgrzyn Silesian University of Technology, Faculty of Materials Engineering and Metallurgy, Katowice, Poland The effect of argon flow intensity on mass loss rate in the carbothermic reduction of SiO2 to SiC was examined. The graphite and natural quartzite in a molar ratio of C/SiO2=3 were used. Samples were reduced for 6 hours at 1 500 °C. In the range of argon flow intensity from 0,1 to 3,4...

Phase variance-based motion contrast is demonstrated using two phase analysis methods in a spectral domain optical coherence tomography system. Mobility contrast is demonstrated for an intensity matched Intralipid solution placed without flow within agarose wells. Vasculature oriented transversely to the imaging direction has been imaged for 3-4 dpf in vivo zebrafish using the phase variance co...

The predictions of the extended predator–prey model of the coupled spectral dynamics of drift wave–zonal flow turbulence are presented. The model exhibits three possible types of time-dependent solutions, depending on system parameters, which are: !1" quasiperiodic bursting of the transport and turbulence intensity levels; !2" oscillatory relaxation to a stationary state, and in the collisionle...

ISSN: 1652-6880, ISBN: 978-91-576-7323-7 Turbulence of various genesis in the left ventricular outflow tract (LVOT) causes systolic ejection murmurs. The prevalence of murmurs in adult boxer dogs is 50-80%, the majority of which are of low ...

The purpose of the present study is to investigate the boundary layer separation point in a magnetohydrodynamics diffuser. As an innovation, the Re value on the separation point is determined for the non-Newtonian fluid flow under the influence of the non-uniform magnetic field due to an electrical solenoid, in an empirical case. The governing equations include continuity and momentum are solve...
