Abstract We show that in viscous approximations of functionals defined on Finsler manifolds, it is possible to construct suitable sequences critical points these satisfying the expected Morse index bounds as Lazer–Solimini’s theory, together with entropy condition Michael Struwe.
The present work presents focuses on the use of different admixtures for development rendering lime-based mortars with improved adhesion and durability, as well reduction cracking. To this aim, combinations an improver (ethylene–vinyl acetate copolymer, EVA), a water repellent agent (sodium oleate), viscosity enhancer (a starch derivative) mineral admixture (pozzolanic addition nanosilica or me...
The aim of this study was to determine the effect ascorbic acid (Vitamin C) as improver in bread on blood glucose response (BGR), Glycemic Index (GI) and Load (GL) healthy subjects. Three concentration namely, 5ppm, 10ppm 15 ppm were added Ab-Graib wheat flour 72 90% extraction making local flat bread. Chemical composition produced sensory properties determined order assess quantity intake by V...
UNLABELLED The aim of the study was to evaluate blood viscosity as possible marker of disease progression in patients with newly diagnosed non-Hodgkin's lymphoma (NHL). METHODS The viscosity of blood samples from 20 patients with newly diagnosed aggressive NHL (stage I, n=7; stage II, n=4; stage III, n=7; stage IV, n=2) was analyzed using Brookfield DV-II + (USA) machine. RESULTS Blood visc...
The effect of solid content (2.5-10%, w/v) and temperature (30-70°C) on the viscosity of tapioca meal from three cassava varieties was investigated in this study. Viscosity measurements were conducted using a digital rotational Brookfield viscometer. The viscosity of tapioca meal increased with increasing solid content and decreasing viscometer speeds. An empirical power-law equation fitted the...
The present study was designed to determine the effects of hemodilution with gelatine (GEL) and hydroxyethyl starch (HES) on hematocrit, blood viscosity, systemic hemodynamics, and central retinal arterial blood flow in anaesthetized pigs. 20 pigs were studied. Hypervolemic hemodilution was induced by 30 ml kg-1h-1 GEL (n=10) or HES (n=10) infused over 30 min. The hematocrit decreased comparabl...
This paper investigates the influence of the effect of viscous dissipation and radiation on natural convection heat transfer from vertical flat plate in a non-Darcy porous media saturated with non-Newtonian fluid of variable viscosity. The wall and the ambient medium are maintained at constant but different levels of temperature. The Ostwald–de Waele power law model is used to characterize the ...
Indica rice starch and japonica rice starch were used in the study. The protein contents of the two rice variety were respectively 0.43%, 0.62%, 0.84%, 1.08%, 1.25%. The pasting and rheological properties of samples were determined with Rapid Visco Analyzer and dynamic rheometer. The results indicated that, with the increase of protein content, the peak viscosity, breakdown viscosity and final ...
