For accurate particle image velocimetry measurements in hemodynamics studies it is important to use a fluid with a refractive index (n) matching that of the vascular models (phantoms) and ideally a dynamic viscosity matching human blood. In this work, a blood-mimicking fluid (BMF) composed of water, glycerol, and sodium iodide was formulated for a range of refractive indices to match most commo...
Three oat cultivars and one oat breeding line were evaluated for chemical, hydration and pasting properties. Protein, starch and β-glucan levels ranged 11.13∼14.37, 56.37∼64.86 and 3.44∼4.76%, respectively. The oat cultivars Daeyang and Seonyang contained higher β-glucan levels of 4.76 and 4.35%. The Daeyang variety had a higher water absorption index (WAI) of 2.83∼3.35 (g/g), but a lower water...
Purpose: To perform stability studies on a nanoemulsion formulation containing beclomethasone dipropionate (BD) and prepared by spontaneous emulsification method. Method: A nanoemulsion (o/w) containing BD was prepared using eucalyptus oil, Tween-40, ethanol and distilled water. The nanoemulsions were characterized by droplet size, pH, viscosity, conductivity and refractive index. Stability stu...
this is an original study on the effect of a polyisobutylene – polydimethylsiloxane (pibpdms) block copolymer modifier used as an interfacial active agent on the dynamics behaviour of single newtonian drops suspended in a polyisobutylene (pib) newtonian matrix. the results were divided in two sections. the first part included the experiments carried out on the non-modified and 2% block cop...
Background: The study of rheological properties of blood has special interest since it is a circulating fluid exposed to shear rates during its life time. This work aims to investigate the influence of whole body gamma irradiation on the rheological properties of rat’s blood. The applied shear rate was from 12 to 375 s-1. Low shear viscosity (up to 100 s-1) depends mainly on the erythroc...
BACKGROUND Body weight, body mass index, fibrinogen concentration and relative plasma viscosity can contribute to the development of hypertension in diabetics. This study compares body weight, body mass index, fibrinogen concentration and relative plasma viscosity between hypertensive diabetics, normotensive diabetics and healthy controls. METHODS The present study was carried out on normoten...
Soils at critical state are like a visco-plastic fluids, which will flow for applied stresses greater than the critical state (CS) shear strength. Shear viscosity is a key parameter to understand the post-failure flow response of soils in geotechnical applications such as landslides, jacked piles and cone penetrometers. Viscosity of soil has been investigated for water contents greater than the...
