The exact knowledge of the blood vessel geometry plays an important role, not only in clinical applications (stroke diagnosis, detection of stenosis), but also for detailed analysis of functional data, such as fMRI or optical imaging data. Here we focus on validating not only the geometry of the extracted vascular pattern, but also its function, namely the fluid dynamics. For validating angiogr...

Background & Aim:  Psyllium (Plantago psyllium L.) is a native plant that grows widely in India and Iran. Different cases of using psyllium gum for its suitable rheological properties in a wide range of food products exist in nature. Experimental: In this study, different fractions of psyllium gum were extracted by water and alkali treatments. Rheological properties of these fractions...

in this research, seeds of iranian carob trees grown wild in kazeroon city (fars province) were used to extract iranian locust bean gum as a seed galactomannan. chemical composition, solubility, and rheological properties of crude and purified gums were investigated and compared with a commercial (sigma) locust bean gum (lbg) sample. chemical composition of the purified iranian lbg was similar ...

In this paper, a model is proposed for the kernel in the generalized mixing rule recently formulated by Anderssen and Mead (1998). In order to derive such a model, it is necessary to take account of the rheological significance of the kernel in terms of the relaxation behaviour of the individual polymers involved. This leads naturally to consider a way how additional physical effects, which dep...

The rheological characteristics of digested sludge are severely temperature dependent. An effect of temperature on rheological properties of digested sludge is partially irreversible. In this paper, the effects of temperature change and thermal history on viscosity of digested sludge were studied using a stress-controlled rheometer which was connected to a temperature controlled water bath. Dig...

Linear low-density polyethylene (LLDPE) based composites were prepared by melt compounding with 1, 2, 3 and 4 vol% of various kinds of amorphous silicon dioxide (SiO2) microand nanoparticles. Dynamic rheological tests in parallel plate configuration were conducted in order to detect the role of the filler morphology on the rheological behaviour of the resulting microand nanocomposites. A strong...

The rheological response of blends obtained from quaternized polysulfone and polyvinyl alcohol in N-methyl-2pyrrolidone as against structural peculiarity of polymers from the blend, composition of polymer mixtures, as well as the types of interactions were investigated. Results show that the variation of polyvinyl alcohol composition in the studied system determines changes of the rheological p...

ISSN 2277-5056 | © 2012 Bonfring Abstract--The workability of fresh concrete should be characterized by its rheological properties based on material science approach to overcome the inadequacies of traditional empirical tests like slump test. Generally the rheological properties of fresh concrete are described by Bingham parameters in terms of two physical quantities, namely yield stress and pl...

The influence of magnetic field on whole blood rheological properties remains a weakly known phenomenon. An in vitro analysis of the magnetic field influence on the rheological properties of healthy persons blood is presented in this work. The study was performed on blood samples taken from 25 healthy nonsmoking persons and included comparative analysis of the results of both the standard rotar...

the motivation for this work is to propose a first thorough review of dough rheological models used in numerical applications. although many models have been developed to describe dough rheological characteristics, few of them are employed by researchers in numerical applications. this article reviews them in detail and attempts to provide new insight into the use of dough rheological models.
