  1. 21. Interactions between whole blood and TiO₂ surfaces with focus on adhesion and activation of PMN granulocytes

    Författare :Cecilia Eriksson; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; titanium; TiO2; surface roughness; oxide thickness; wettability; whole blood; inflammation; wound healing; platelets; PMN granulocytes; adhesion; activation; receptor expression; respiratory burst.;

    Sammanfattning : Foreign materials come in contact with the human body more and more frequently. The surgical procedure of inserting an implant into the body will cause bleeding, evoke an inflammatory response and initiate a healing process, ultimately leading to acceptance or rejection of the material.

  4. 23. Regimented language training : Changes to brain and behaviour following intensive non-native language learning

    Författare :Johan Mårtensson; Institutionen för psykologi; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Cortical thickness; Hippocampus; Plasticity; Language acquisition; Associative memory; Transfer; Education;

    Sammanfattning : The influence of foreign-language acquisition on adult brain structure remains mostly unexplored. Whilst several cross-sectional studies have led to further understanding of how language can affect brain structure, only a few longitudinal studies have been conducted. LÄS MER

  5. 24. Hydrodynamics and Heat Transfer in Vertical Falling Films with Smooth and Modified Heat-Transfer Surfaces – An Experimental and Numerical Investigation

    Författare :Anders Åkesjö; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; film thickness; local heat transfer coefficient; numerical simulations; heat transfer; falling film; VOF; evaporation.;

    Sammanfattning : High energy utilization efficiency is important to achieve a sustainable society. By having highly efficient heat exchangers, more energy can be recovered and reused at a lower cost. LÄS MER

  7. 25. Anchorage in Concrete Structures : Numerical and Experimental Evaluations of Load-Carrying Capacity of Cast-in-Place Headed Anchors and Post-Installed Adhesive Anchors

    Författare :Rasoul Nilforoush; Lennart Elfgren; Norbert Randl; Karin Lundgren; Manouchehr Hassanzadeh; Richard Malm; Lars-Erik Persson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Headed anchor; Anchor bolt; Adhesive anchor; Concrete cone breakout; Concrete splitting; Pullout loading; Size effect; Member thickness; Anchor head size; Orthogonal surface reinforcement; Concrete Strength; High-strength concrete; Cracked concrete; Steel fiber-reinforced concrete; Sustained loading; Creep behavior; Structural Engineering; Konstruktionsteknik;

    Sammanfattning : Various anchorage systems including both cast-in-place and post-installed anchors have been developed for fastening both non-structural and structural components to concrete structures. The need for increased flexibility in the design of new structures and strengthening of existing concrete structures has led to increased use of various metallic anchors in practice. LÄS MER
