Water-soluble polyacrylamides have often been used to modify flow response in various water-based technologies and industrial processes, including paints, water treatment, paper manufacturing, and chemical enhanced oil recovery. Polymers are susceptible to degradation at combined high salinity and elevated temperature conditions which limits...

The expected increase of global obesity prevalence makes it necessary to have information about the effects of meal intakes on the feeling of appetite. Because human clinical studies are time and cost intensive, there is a need for a reliable alternative. The aim of this study was to develop and evaluate an in vitro-in silico technology to...

Non-contact printing techniques are receiving increasing interest in the field of printed electronics, because they can be used to pattern various inks on arbitrary substrates without applying mechanical pressure or damaging pre-patterned components. The ink-jet process is frequently used for non-contact printing of various conductive inks....

Research on human skin interactions with healthcare and lifestyle products is a topic continuously attracting scientific studies over the past years. It is possible to evaluate skin mechanical properties based on human or animal experimentation, yet in addition to possible ethical issues, these samples are hard to obtain, expensive and give rise...

The main objective of this paper is to understand the physical processes of shut-in and restart of viscous multiphase flowline. For this purpose, experiments were performed on shut-in and restart processes in the Multiphase Flow Rig at Statoil's research Centre in Porsgrunn. Real crudes were used with oil viscosity up to 30,000 cP at room...

In [M. A. Ainslie & T. G. Leighton, Underwater Acoustic Measurements (Heraklion, Crete, 2007), pp 571-576], the authors described a discrepancy between the radiation damping coefficients in the models due to Weston and to Medwin describing the scattering cross-section of a single spherical bubble. The resolution of that discrepancy [M. A....

Several series of nanocomposites were prepared using a latex-based process, the main step of which consisted of mixing an aqueous suspension of exfoliated carbon nanotubes (CNTs) and a polymer latex. In the present work, a systematic study on the electrical properties of fully amorphous (polystyrene - PS) as well as semi-crystalline (isotactic...

The preparation of a yellow dextrin is thoroughly characterized during different stages of its production process with a SEC system equipped with four detectors (light scattering, viscosity, UV and RI). With this system, also referred to as SEC-4D, it was shown that the changes in characteristics are only in line with initial expectations up to...

Background: An important question in the regulation of energy intake is whether dietary learning of energy content depends on the food's characteristics, such as texture. Texture might affect the duration of sensory exposure and eating rate. Objective: The objective was to investigate whether a long sensory exposure, due to differences in means...

A higher viscosity of a food leads to a longer orosensory stimulation. This may facilitate the learned association between sensory signals and metabolic consequences. In the current study we investigated the effect of viscosity on learned satiation. In two intervention groups a low viscosity (LV) yogurt (n = 24) and a high viscosity (HV) yogurt ...

Key properties of organic coatings, such as mechanical strength and solvent resistance, are greatly influenced by the structure of the polymeric binder. In general, a 3-dimensional polymeric network gives the best properties and therefore most performance coatings have a 3-dimensional network structure. However, 3-dimensional networks cannot...

This study explored relationships between physical/chemical and sensory properties using a set of 20 low-fat and non-fat cream cheeses. High correlations were found between several descriptors; hand resistance (i.e., tactile firmness) was best predicted by squeezing flow viscometry (r = 0.90) and followed by dynamic oscillation (r = 0.86),...

Vibromyography was used to quantify oral activity during the processing of well-characterized semi-solid model foods whilst subjects assessed the intensity of the sensory attributes to thick, creamy, melting, fatty, rough and liking. A series of eleven starch-based vanilla custard desserts was prepared with five different viscosities, three...

Predictability of the perception of foods thickened by polysaccharides is only poor. Therefore, the effect of saliva on the lubrication properties of 2 types of neutral polysaccharides, cross-linked starch and locust bean gum, was studied. Despite the similar bulk rheological behavior of the 2 polysaccharides, the starch solution exhibited a...

Two studies investigated the effect of a food's viscosity on bite size, bite effort and food intake using a standardized protocol in which subjects sipped through a straw every 20 s for a period of 15 min from one of two products, a chocolate-flavored dairy drink and a chocolate-flavored dairy semi-solid, matched for energy density. In the first...

A self-replicating vector was designed that enables the construction of complex libraries in the fungus Chiysosporium lucknowense. The circular vector is linearized in vivo and results in a transformation frequency up to 13,000 transformants/ug ofplasmid DNA. Upon prolonged cultivation of the transformants in liquid medium, the linearized vector...

There is a large interest in mixed protein/polysaccharide layers at air-water and oil-water interfaces because of their ability to stabilize foams and emulsions. Mixed protein/polysaccharide adsorbed layers at air-water interfaces can be prepared either by adsorption of soluble protein/ polysaccharide complexes or by sequential adsorption of...

A dynamic model for describing the build-up and breakdown of a glass-melt foam is presented. The foam height is determined by the gas flux to the glass-melt surface and the drainage rate of the liquid lamellae between the gas bubbles. The drainage rate is determined by the average gas bubble radius and the physical properties of the glass melt:...
