  1. 1. On the influence of biochemical coating on implant bone incorporation

    Författare :Kostas Bougas; Malmö högskola; []

    Sammanfattning : Implantat används idag med goda resultat för att ersätta förlorade tänder. Tandimplantat opereras in i käkbenet och agerar som en konstgjord rot för en konstgjord tand eller för att förankra en protes. Implantatens ytor har utvecklas med åren från att vara släta till måttligt råa. LÄS MER

  2. 2. Perceived Quality of Cars. A Novel Framework and Evaluation Methodology

    Författare :Kostas Stylidis; Chalmers University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; HUMANIORA; ENGINEERING AND TECHNOLOGY; HUMANITIES; ; luxury; knowledge management; engineering; premium; design; engineering; automotive; product quality; product development; aesthetics; perceived quality;

    Sammanfattning : The supremacy of the automotive manufacturers today is no longer driven by them achieving a superior manufacturing quality but increasingly depends on the customer’s quality perception. Average car consumers see a car’s quality as a fancy mixture of design, aesthetics, their own previous experiences and performance characteristics of the vehicle, unlike a combination of mechanical parts, software pieces, advanced materials, cutting-edge manufacturing processes, with technical knowledge, skills and high production volumes – all ingredients involved in the modern car creation.

  3. 3. HiPIMS-based Novel Deposition Processes for Thin Films

    Författare :Asim Aijaz; Ulf Helmersson; Kostas Sarakinos; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : In this research, high power impulse magnetron sputtering (HiPIMS) based new deposition processes are introduced to address; the issue of low degree of ionization of C in magnetron sputtering discharges, and the difficulty encountered in thin film deposition on complex-shaped surfaces. The issue of low degree of C ionization is addressed by introducing a new strategy which is based on promoting the electron impact ionization ofC by increasing the electron temperature in the plasma discharge using Ne, instead of conventionally used Ar.

  4. 4. Synthesis of Carbon-based and Metal-Oxide Thin Films using High Power Impulse Magnetron Sputtering

    Författare :Asim Aijaz; Ulf Helmersson; Kostas Sarakinos; Günter Bräuer; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : The work presented in this thesis deals with synthesis of carbon-based as well as metal-oxide thin films using highly ionized plasmas. The principal deposition method employed was high power impulse magnetron sputtering (HiPIMS). LÄS MER

  5. 5. Characterization of Physiological and Pathological Alpha-Synuclein : Implications for Parkinson’s Disease and Related Disorders

    Författare :Leire Almandoz Gil; Joakim Bergström; Martin Ingelsson; Kostas Vekrellis; Uppsala universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; NATURAL SCIENCES; MEDICAL AND HEALTH SCIENCES; Alpha-synuclein; Aggregation; Parkinson’s disease; Dementia with Lewy bodies; Oxidative stress; Antibodies; Synapses; SNARE; Molekylär medicin; Molecular Medicine;

    Sammanfattning : Aggregated alpha-synuclein is the main component of Lewy bodies and Lewy neurites, intraneuronal inclusions found in the brains of Parkinson’s disease (PD) and dementia with Lewy bodies (DLB) patients (synucleinopathies). Alpha-synuclein is a presynaptic protein, which is most commonly an unfolded monomer in its physiological state. LÄS MER
