  1. 1. Implementation of Flexible Automatic Assembly in Small Companies : Flexibility and Process demands

    Författare :Roger Johansson; Högskolan Dalarna; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Assembly automation; Flexibility; Modularity;

    Sammanfattning : This thesis has its focus within Flexible Automatic Assembly (FAA) systems and its implementation in small companies. The small companies are an important part of a country’s industry and economy. The need for the small company to increase the technology level, in order to be competitive in a global market as a supplier, is evident. LÄS MER

  3. 2. Reactive sputtering and composition measurements of precursors for Cu2ZnSnS4 thin film solar cells

    Författare :Tove Ericson; Charlotte Platzer-Björkman; Tomas Kubart; Marika Edoff; Anders Hallén; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cu2ZnSnS4; Kesterite; Reactive sputtering; Process curve; Photovoltaics; Composition measurments; Teknisk fysik med inriktning mot elektronik; Engineering Science with specialization in Electronics;

    Sammanfattning : Cu2ZnSnS4 (CZTS) is a thin film solar cell material that only contains abundant elements and for which promising conversion efficiencies of 9.2 % have been shown. In this thesis composition measurements and reactive sputtering of precursors for CZTS films have been studied. These precursors can be annealed to create high quality CZTS films. LÄS MER

  4. 3. Pseudomyxoma Peritonei : Aspects of Natural History, Learning Curve, Treatment Outcome and Prognostic Factors

    Författare :Håkan Andréasson; Haile Mahteme; Lars Påhlman; Brendan Moran; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pseudomyxoma peritonei; Natural history; Learning curve; Cytoreductive surgery; Debulking surgery; Treatment outcome; Prognostic factors; PINCH;

    Sammanfattning : Pseudomyxoma peritonei (PMP) is a rare disease characterized by mucinous peritoneal metastasis (PM). Different loco-regional treatment strategies, i.e. debulking surgery and cytoreductive surgery (CRS) in combination with hyperthermic intraperitoneal chemotherapy (HIPEC), have changed the prognosis for these patients.

  5. 4. Chemometric methods for analysis of spectroscopic data from batch process monitoring

    Författare :Erik Furusjö; KTH; []
    Nyckelord :in situ spectroscopy; reaction monitoring; organic synthesis; solubility; crystallization; multivariate calibration; curve resolution; kinetic model; reaction rate constant; activation energy; target testing; bootstrap;

    Sammanfattning : Understanding of a process is essential for processdevelopment, optimisation and scale-up. In situ spectroscopy isan attractive measurement technique that can increase processunderstanding, since samples need not be retrieved from theprocess mixture. LÄS MER

  7. 5. The immortalization process of T cells : with focus on the regulation of telomere length and telomerase activity

    Författare :Sofie Degerman; Göran Roos; John Sedivy; Umeå universitet; []
    Nyckelord :immortalization; senescence; T cells; Nijmegen breakage syndrome; telomere; telomerase; hTERT; generic aberrations; methylation; MEDICINE; MEDICIN; Pathology; patologi;

    Sammanfattning : Cellular immortalization is a major hallmark of cancer and is a multi-step process that requires numerous cell-type specific changes, including inactivation of control mechanisms and stabilization of telomere length. The telomeres at the chromosome ends are essential for genomic stability, and limit the growth potential of most cells. LÄS MER
