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 ...

Microemulsions (MEs) are colloidal systems that can be used for drug-delivery and drug-targeting purposes. These systems are able to incorporate drugs modifying bioavailability and stability and reducing toxic effects. The jasmonate compounds belong to a group of plant stress hormones, and the jasmonic acid and its methyl ester derivative have been described as having anticancer activity. Howev...

Sickle-cell anaemia (SCA) is an inherited blood disorder exhibiting heterogeneous cell morphology and abnormal rheology, especially under hypoxic conditions. By using a multiscale red blood cell (RBC) model with parameters derived from patient-specific data, we present a mesoscopic computational study of the haemodynamic and rheological characteristics of blood from SCA patients with hydroxyure...

Functional breads constitute an interesting alternative as vehicle of new essential fatty acids sources. The aim of this study was to improve the fatty acids (FA) profile of bakery products, producing breads with low saturated fatty acid (SFA) content and with high polyunsaturated fatty acid (PUFA) content, through partial substitution of wheat flour by other ingredients (soy flour, flax flour,...

The purpose of this study is to discuss the significant role α-amylase enzyme in production and rheological characteristics gluten-free rice dough baked bread. Small deformation large methods were used evaluate effect addition on bread characteristics. baking properties evaluated by specific volume, loss, Texture profile analysis parameters. added microstructure was also evaluated. doughs showe...

Five different procedures were used to isolate potato starch from the same batch at three different scales in order to analyse what influence scaling up of the starch process had on the starch physical/chemical properties. Common to the five isolation processes was the steps of washing and maceration of potato tubers followed by separation of starch and cell debris by sieving, filtration or sed...

OBJECTIVES The purpose of this study was to investigate the viscoelastic properties related to the handling characteristics of composites. METHODS A custom-designed vertical oscillation rheometer (VOR) was used for the rheological measurements of composites. The VOR consists of three parts: (1) a measuring unit, (2) a deformation induction unit, and (3) a force-detecting unit. Two medium-visc...

Objective: The objective of this study was to examine and characterize topical eye drops with indomethacin-loaded poly(vinyl acetate) nanoparticles (IMC-p(VAc)-NPs). Methods: IMC-p(VAc)-NPs were obtained by emulsifier-free radical homopolymerization of the monomers in the presence of indomethacin in water and in an aqueous solution of Carbopol®. Thus obtained indomethacin nanocarriers were incl...

This study was performed to investigate the chemical and rheological properties of composite flours prepared by using whole wheat flour (Triticum aestivum), whole maize flour (Zea mays) and whole sorghum flour (Sorghum bicolor). Seven blends were prepared by homogenously mixing maize and sorghum flours with wheat flour in the percentage proportions: 0:100, 10:90, 20:80, 30:70, 15:15:70 (MF: WWF...

For realizing the intelligent vehicle suspension design with magneto-rheological (MR) fluids dampers, extensive laboratory measurements are performed to characterize the symmetric and asymmetric hysteresis force properties of a MR-damper, under a wide range of drive current and harmonic excitation conditions (frequency and stroke). The proposed asymmetric damping force generation (ADFG) algorit...
