2. 1. Rheological Behaviour of Biopolymer Gels in Relation to Structure

   Author : Mats Stading; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; particulate gels; fine-stranded gels; mixed gels; biopolymer gels; inhomogeneous gels; rheological properties; rheological behaviour;

   Abstract : The rheological behaviour of biopolymer gels with different network structures was studied to elucidate how the structure of the gel influences its rheological properties. Non-destructive viscoelastic measurements and fracture techniques were used. READ MORE

4. 2. Rheological Properties of Microfibrillated Cellulose

   Author : Tobias Moberg; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; rheological properties; creep; Extensional viscosity; Microfibrillated cellulose; suspensions; ;

   Abstract : Cellulose has for a long time been used by man. It is renewable and an easily recyclable resource. Mostly it has been used in either its native form as wood or in the form of fibres. READ MORE

5. 3. Wheat Flour Dough-Rheological and Structural Aspects

   Author : Helena Larsson; Livsmedelsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; starch gel; gluten; water distribution; lipids; starch granule surface; starch content; mixing; ultracentrifugation; structure; rheological measurements; wheat flour dough; phase separation; ethyl hydroxyethyl cellulose; Food and drink technology; Livsmedelsteknik;

   Abstract : The thesis presents a rheological study on wheat flour dough, in relation to the structural influence of the different dough constituents, added components and mixing time. Rheological investigations have been focused on measurements at small deformations, including dynamic oscillation and stress relaxation, although complementing measurements have been performed in large deformation viscosity experiments.

7. 5. Rheological properties of lubricating fluids

   Author : Jan Lundberg; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Machine Elements; Maskinelement;

   Abstract : Obliteration (gobbing) caused by water based lubricating fluids is studied experimentally by analyzing the flow through a small channel. Flow measurements, energy dispersive X-ray microscopy and photos show, that the rate of gobbing depends on which type of fluid that is being used. READ MORE
