2. 1. Numerical study of particle suspensions in Newtonian and non-Newtonian fluids

   Author : Dhiya Alghalibi; Luca Brandt; Metin Muradoglu; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; inertial suspensions; rheology; non-Newtonian fluids; visco-elastic; sedimentation; deformable particle; hyper-elastic.; tröghetsbehäftad suspension; reologi; icke-Newtonska fluider; vis- koelastik; sedimentering; deformerbara partiklar; hyperelastik; Engineering Mechanics; Teknisk mekanik;

   Abstract : Solid or deformable particles suspended in a viscous fluid are of scientific and technological interest in a broad range of applications. Pyroclastic flows from volcanoes, sedimentation flows in river bed, food industries, oil-well drilling, as well as blood flow in the human body and the motion of suspended micro-organisms in water (like plankton) are among the possible examples.

4. 2. Modelling tools for quieter vehicles : Waves in poro– and visco–elastic continua

   Author : Martin Östberg; Leif Kari; Jenny Jerrelind; Sergey Sorokin; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vibro-acoutics; poro-elastic; visco-elastic; reduced models; Harmonic expansion; wave guide;

   Abstract : New modelling tools intended to contribute to the development of components for quieter vehicles are developed. The tools are based on continuum models for wave propagation in poro– and visco–elastic media. By using geometric attributes of the studied components, the computational cost may be radically decreased compared to traditional methods. READ MORE

5. 3. Floor vibration : dynamic properties and subjective perception

   Author : Fredrik Ljunggren; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknisk akustik; Engineering Acoustics;

   Abstract : This thesis covers research in the floor vibration field. Although lightweight steel framed constructions have been in focus, many results are applicable to floors in common and to some extent also to vibrations in general. READ MORE

6. 4. Interfacial Properties of Film Forming Proteins and their Layer-by-Layer Assembly with Nanoparticles

   Author : Olga Krivosheeva; Per Claesson; Thomas Arnebrant; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; protein adsorption; mussel adhesive protein; Mefp-1; hydrophobins; HFBI; HFBII; adsorption kinetics; layer-by-layer; stability; cross-linking; zeta-potential; dual polarization interferometry; quartz crystal microbalances;

   Abstract :  The aim of this thesis work was to investigate the interfacial properties of film forming proteins, stability of the layers created by them, and their interactions with nanoparticles. Mussel adhesive protein (Mefp-1) and hydrophobins (HFBI and HFBII) were the three main proteins used. READ MORE

7. 5. Mechanisms of adaptation in a mechanoreceptor : a study of mechanical and ionic factors in the crayfish stretch receptors

   Author : Nuhan Purali; Karolinska Institutet; Karolinska Institutet; []
   Keywords : Crayfish; stretch receptor; adaptation; visco-elastic properties; mechanosensitive channels; potassium channels; sodium channels; gadolinium; tetraethylammonium chloride; 4-amino pyridine; scorpion venom Leiurus quinquestrialus;

   Abstract : The stretch receptor organ of the crayfish, an analog to the human muscle spindle, is a unique preparation for the study of mechanotransduction. The organ consists of a rapidly and a slowly adapting receptor each composed of a receptor muscle fibre into which inserts the dendrites of a multipolar sensory neuron. READ MORE
