the effect of different extraction rates (64%, 82% and 90%) of wheat flour on the rheological properties of the wheat flour dough was investigated. a complete study of the rheological behavior of the wheat flour dough was performed by using three different instruments namely alveograph, extensograph, and farinograph. the correlation coefficient among the various parameters of applied methods wa...

– We use a lattice Boltzmann (LB) kinetic scheme for modelling amphiphilic fluids that correctly predicts rheological effects in flow. No macroscopic parameters are included in the model. Instead, three-dimensional hydrodynamic and rheological effects are emergent from the underlying particulate conservation laws and interactions. We report evidence of shear thinning and viscoelastic flow for a...

Systems of partial differential equations that include the momentum and the mass conservation equations are commonly used for the simulation of debris flow initiation, propagation and deposition both in field and in laboratory research. The numerical solution of the partial differential equations can be very complicated and consequently many approximations that neglect some of their terms have ...

In this study, synthetic sulfonated polymers were used in order to enhance the rheological properties of drilling fluids. The capability of these polymers in reducing the effects of environmentally friendly, but harmful, pollutants such as cement, calcium chloride, gypsum as well as pH changes were investigated. In the present work, two sulfonated synthetic polymers, namely Polythin and Polydri...

The aim of this study was to characterize and optimize the different hydrogel formulations of the methanolic root extract of Buchanania lanzan (MEBL) with an objective towards the development of a suitable topical delivery system. The gel formulations were prepared with different concentrations of polymer (Carbopol-940) and 0.5% of the active fraction (ethyl acetate sub-fraction of MEBL). Diffe...

The theological parameters of a clay suspension can be used to evaluate particle-particle interactions. Although there have been many studies of the rheological behavior of suspensions of reference clays, only few studies were performed with suspensions of mixed clays, and the rheological properties of these suspensions are not yet fully understood. The length-to-width ratio of some soil clays ...

There are many kinds of deformable objects in our living life. Some of them demonstrate rheological behaviors, such as human tissues, food, and clay. Comparing with elastic or viscoelastic objects, rheological objects have not been studied intensively. Especially, effective methods for parameter identification have not been established until now. In this paper, we summarize two FE dynamic model...

Transportation of unrefined crude oil from the production unit to a refinery or large storage area by a pipeline is difficult due to the different properties of crude in various areas. Thus, the design of a crude oil pipeline is a very complex and time consuming process, when considering all the various parameters. There were three very important parameters that play a significant role in the t...

This study seeks to demonstrate the influence of pharmacological substances from the SYSADOA group on the progression of osteoarthritis in the human knee. The quantification methods were direct measurement of the rheological properties of the knee joints in vivo and standard WOMAC index questionnaires. The drugs were administered orally to 34 probands with second degree gonarthrosis for 13 week...
