  1. 1. Head and Neck Cancer : Factors Affecting Tumour Growth

    Författare :Kaarina Sundelin; Elisabeth Paulette-Hultcrantz; Karin Öllinger; Karin Roberg; Hans Gustafsson; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Head and neck cancer; Chemoradiotherapy; Tumour; Malignant salivary; Metallothionein; Neo-angiogenesis; Metastases; Cytokine tumour necrosis factor-alpha; hepatocyte growth factor; Oncology; Onkologi;

    Sammanfattning : Head and neck cancer is the fifth most common cancer worldwide with an estimated annual global incidence of over 500 000 cases. These malignant tumours develop in the mucosal linings of the upper respiratory tract or in the salivary glands. The most common sites are in the oral cavity and larynx. LÄS MER

  3. 2. High temperature performance of materials for future power plants

    Författare :Junjing He; Pavel Korzhavyi; Rolf Sandström; Stefano Spigarelli; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Austenitic stainless steels; Nickel based superalloys; Low cycle fatigue; Creep-fatigue; Creep cavitation; Grain boundary sliding; Cavity nucleation; Cavity growth; Creep rupture strength; Advanced ultra-supercritical power plants.; Teknisk materialvetenskap; Materials Science and Engineering;

    Sammanfattning : Increasing energy demand leads to two crucial problems for the whole society. One is the economic cost and the other is the pollution of the environment, especially CO2 emissions. Despite efforts to adopt renewable energy sources, fossil fuels will continue to dominate.

  4. 3. InP based Micromechanics for Vertical-Cavity Micro-Opto-Electro-Mechanical Systems

    Författare :Martin Strassner; KTH; []
    Nyckelord :MOEMS; vertical-cavity; InP; DBR; epitaxy; semiconductor processing; micromechanics; wavelength tunable devices; long-wavelength;

    Sammanfattning : During the past decade, the amount of transmitted data hasbeen boosted due to an increasing use of the World Wide Web(WWW), video and audio transmissions. In the late 90s, thetraditional technology using twisted copper cables was nolonger capable to provide enough transmission capacity for theconstantly increasing data traffic. LÄS MER

  5. 4. Free-space cavity optomechanical systems on a chip with III-V heterostructures

    Författare :Sushanth Kini; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Optomechanics; Micromechanical resonators; Cavity Optomechanics; III-V materials; Photonic crystals;

    Sammanfattning : Cavity optomechanics examines the mutual interaction between light and mechanical motion for controlling mechanical resonators down to the quantum regime. A major challenge in the field of cavity optomechanics remains accessing a strong interaction between the light field and mechanics on the level of single quanta. LÄS MER

  7. 5. Prostate cancer and bone cell interactions : implications for metastatic growth and therapy

    Författare :Annika Nordstrand; Pernilla Wikström; Anders Widmark; Jonas Nilsson; Päivi Östling; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; onkologi; Oncology;

    Sammanfattning : The skeleton is the most common site of prostate cancer bone metastasis, and at present, there are no curable treatments for these patients. To further understand what stimulates tumor cell growth in the bone microenvironment and to find suitable therapies, reliable model systems are needed. LÄS MER
