Flow and dynamic rheological properties of hot thickened soups for consumption by the elderly people with swallowing difficulty (dysphagia) were investigated at a serving temperature of 60°C. In this study, sea mustard soup (SMS) and dried pollock soup (DPS), which have been widely known as favorable hot soups provided in a domestic hospitals and nursing homes for dysphagic patients, were thick...

a novel mixing approach for achieving a good dispersion of multi-walled carbon nanotubes (mwcnts) in ethylene- propylene diene monomer (epdm) matrix has been investigated. in this approach epdm was modified with vinyltrimethoxysilane (vtms) during melt mixing. in addition the effect of mwcnt concentration on mechanical and rheological properties of modified epdm has been studied. the formulated...

emulsion stability, viscoelastic rheological properties and particle size distribution of french dressing samples formulated with two types of commercial modified starch have been investigated. the product’s usual thickening agents, xanthan and guar gum, were 100% substituted by (2, 2.2%) of acetylated distarch adipate (ada) and hydroxypropylated distarch phosphate (hdp) from waxy maize starch....

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...

in this work, we studied the effect of carboxylic acid on the rheological properties of a high-alumina cement mortar (ch45) produced by the algerian firm refractal.the investigated properties are setting time, water consumption, electrical conductivity, ph, density and the compressive strength. the results show a setting time of about 200 min for the acid free, 180 min with 0.1 % of carboxylic ...

To gain insight into cellular mechanotransduction pathways, we have developed a fluorescence laser tracking microrheometer (FLTM) to measure material rheological features on micrometer length scales using fluorescent microspheres as tracer particles. The statistical analysis of the Brownian motion of a particle quantifies the viscoelastic properties of the probe's environment, parameterized by ...

Frontal polymerization has been successfully used to synthesize poly(N-isopropylacrylamide) nanocomposite hydrogels containing graphene. The latter was directly achieved by ultrasound treatment of a dispersion of graphite inN-methylpyrrolidone. The dispersion, having the concentration of 2.21 g L , was characterized by TEM analysis and mixed with suitable amounts of N-isopropylacrylamide for th...

This paper undertakes a parallel analysis of the gelation mechanisms, structure and rheological properties of gelatin and collagen gels. Although the molecular compositions of collagen and gelatin are almost identical, gelation proceeds from distinct mechanisms and leads to different types of molecular assemblies. First are presented the properties of the solutions, based on their structural an...

Biomaterials are materials that are employed to replace or enhance a bodily function and, as such, are commonly used in modern medicine. The performance of these systems is directly related to their viscoelastic properties. This paper provides an overview of the importance of such properties and how they may be manipulated to achieve optimal performance. INTRODUCTION In recent years medicine ha...

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...
