We investigated experimentally the rheological behavior of whole human blood subjected to large amplitude oscillatory shear under strain control to assess its nonlinear viscoelastic response. In these rheological tests, the shear stress response presented higher harmonic contributions, revealing the nonlinear behavior of human blood that is associated with changes in its internal microstructure...

Rheological measurements are quite relevant in the food industry as a tool for physical characterization of raw material prior to processing, for intermediate products during manufacturing, and for finished foods. There are several approaches to conduct these rheological characterizations, and the selected technique pretty much depend on the specific product and the functional characteristics i...

The primary purpose of this chapter is to present an approach for developing nonparametric models for magneto-rheological (MR) dampers. Upon describing the approach adopted here, a non-parametric model for a commercial magneto-rheological damper is developed, and is compared with a parametric model from an earlier study. The results show that the proposed non-parametric model can more effective...

Magnetorheological fluids have received widespread attention as smart materials due to their tunable properties. MRF consists of three key components including, soft magnetic particles, carrier liquids, and additives. This review details the characteristics, composition, and rheological principle of MRF, working principle of MRF devices, and their applications in other engineering arenas. The a...

We have applied rheological methods for the analysis of ethanol-lysozyme interaction during the process of denaturation and aggregation of the protein. At low concentration of ethanol a destruction of the hydration shell of lysozyme is observed. With the increase in the ethanol concentration a structural transformation takes place. It leads to the formation of a protein aggregate with an elonga...

To understand the dynamic rheological behavior of polar molecular electrorheological (PMER) fluids, the shear stress and viscosity of the colloids are compared with the parameters of their lamellar structures which are obtained simultaneously with the rheological characteristics using an electrorheoscope. The results of the experiments and molecular dynamics simulation indicate that the shear s...

Background: Tailings dams are made up of mining residue deposits, and they represent a high risk, in terms of mechanical instability. In the event of collapse, the tailings in such dams may be released and flow over long distances, with the potential risk of extensive damage to property and life. The traditional geotechnical assessment of tailings facilities has mainly concentrated on the stabi...

Optimisation of composite flour comprising pearl millet, kidney beans and tigernut with xanthan gum was evaluated for rheological evaluations. The functional properties of the composite flour were optimized using optimal design of response surface methodology. The optimum blends, defined as blends with overall best functional characteristics were run 3 (75.956% pearl millet, 17.692% kidney bean...

in this study, the possibility of including probiotic starter cultures for making yoghurt was investigated. set yoghurts were made using three bio-cultures, all containing bifido-bacterium spp.. the effects of these starter cultures and total solids (i.e. addition of 0, 1 and 2% skim milk powder) on the rheological and sensory characteristics of the bio-yoghurts were compared with a standard st...
