  1. 11. Microstructure and rheological properties of plant particle suspensions prepared using different physical treatments

    Författare :Patricia Lopez-Sanchez; Chalmers tekniska högskola; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; yield stress; rheology; elastic modulus; cell wall; tomato; broccoli; plant particle suspension; microstructure; carrot;

    Sammanfattning : Suspensions of plant particles are very common products or by-products in many industries such as food, paper and biofuel. An improved understanding of the complex relationship between microstructure and rheology of these plant systems might help design, control and predict their structural and material properties.

  3. 12. Cohesive modelling of the temperature dependence of epoxy based adhesives in Mode I and Mode II loading

    Författare :Tomas Walander; Ulf Stigh; Anders Biel; Erik Serrano; Högskolan i Skövde; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cohesive laws; Epoxy adhesive; Fracture energy; Peak stress; Temperature; Regression analyses; Shear modulus; Young’s modulus.; Technology; Teknik;

    Sammanfattning : In this work, the influence of the temperature on the cohesive laws for two epoxy adhesives is studied at temperatures below the glass transition temperature for both Mode I and Mode II loading. Cohesive laws are measured experimentally under quasi-static loading conditions in the temperature range -30≤T≤80"C" . LÄS MER

  4. 13. Can Bone Void Fillers Carry Load? : Behaviour of Calcium Phosphate Cements Under Different Loading Scenarios

    Författare :Ingrid Ajaxon; Cecilia Persson; Caroline Öhman-Mägi; Uwe Gbureck; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Calcium phosphate; bone cement; brushite; apatite; monetite; porosity; solvent exchange; degradation; compressive strength; diametral tensile strength; flexural strength; elastic modulus; Poisson’s ratio; fatigue; Teknisk fysik med inriktning mot materialvetenskap; Engineering Science with specialization in Materials Science;

    Sammanfattning : Calcium phosphate cements (CPCs) are used as bone void fillers and as complements to hardware in fracture fixation. The aim of this thesis was to investigate the possibilities and limitations of the CPCs’ mechanical properties, and find out if these ceramic bone cements can carry application-specific loads, alone or as part of a construct.

  5. 14. On the determination of diffusion coefficients in bone

    Författare :Abdallah Shokry; Hållfasthetslära; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Kalman filter; Mathematical model; Spatially dependent diffusion; Diffusion in bone; Diffusion coefficient; Conductivity; Elastic modulus; Porous materials;

    Sammanfattning : Diffusion in bone is needed for bone remodeling and bone healing. Understanding the phenomenon is often important for comprehension bone diseases. Mathematical modeling of the diffusion processes is a required prerequisite in the study of this important physical process in living bone tissue. LÄS MER
