  2. 6. Solution-Chemically Derived Spectrally Selective Solar Absorbers : With System Perspectives on Solar Heating

    Author : Tobias Boström; Ewa Wäckelgård; Gunnar Westin; Björn Karlsson; Peter Lund; Uppsala universitet; []
    Keywords : Materials science; solar; thermal; absorber; selective; chemical; Materialvetenskap;

    Abstract : This thesis consists of two parts, one dominating part concerning spectrally selective solar absorbers and one dealing with thermal solar systems. The appended papers I to VIII concern the solar absorber part, papers dealing with the systems part have not been included in the thesis. READ MORE

  4. 7. Synthesis of well arrayed structures with assistance of statistical experimental design

    Author : Yajuan Cheng; Pär Jösson; Zhe Zhao; Gunnar Westin; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; optimization; experimental design; statistical analysis; monolayer arrays of silica spheres; vertically aligned ZnO rod arrays; Materials Science and Engineering; Teknisk materialvetenskap;

    Abstract : During the synthesis of well arrayed nano/micro structures through wet chemical methods, plenty of parameters are usually involved. Consequently, it is extremely time- and cost-consuming to find out the optimized synthesis conditions by using the conventional "changing one separate factor at a time" (COST) strategy. READ MORE

  5. 8. Genetic Aspects of Endocrine Tumorigenesis : A Hunt for the Endocrine Neoplasia Gene

    Author : Alberto Delgado Verdugo; Peyman Björklund; gunnar westin; Per Hellman; Filip Farnebo; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Exome sequencing; SDHAF2; epigenetics; methylation; methylation array; Sanger sequencing; pheochromocytoma; SI-NETs; carcinoid; oncology; endocrine surgery; parathyroid; Genetics; Genetik; Kirurgi; Surgery;

    Abstract : Endocrine tumors arise from endocrine glands. Most endocrine tumors are benign but malignant variants exist. Several endocrine neoplasms display loss of parts of chromosome 11 or 18, produce hormones and responds poorly to conventional chemotherapeutics. The multiple endocrine neoplasia syndromes are mainly confined to endocrine tumors. READ MORE

  6. 9. Small Intestinal Neuroendocrine Tumours : Genetic and Epigenetic Studies and Novel Serum Biomarkers

    Author : Katarina Edfeldt; Peter Stålberg; Per Hellman; Gunnar Westin; Malin Sund; Endokrinkirurgi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; SI-NET; microarray; tumour suppressor gene; epigenetic; serum biomarkers; Kirurgi; Surgery;

    Abstract : Small intestinal neuroendocrine tumours (SI-NETs) are rare, hormone producing and proliferate slowly. Patients usually display metastases at time of diagnosis, the tumours are difficult to cure, and the disease course is unpredictable. READ MORE

  7. 10. Pancreatic Endocrine Tumourigenesis : Genes of potential importance

    Author : Térèse A. Johansson; Barbro Eriksson; Britt Skogseid; Gunnar Westin; Martin Bäckdahl; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pancreatic endocrine tumour; Multiple endocrine neoplasia type 1; Tumourigenesis; Notch signalling; Notch1; Hes1; Neurog3; Neurod1; Men1; Ascl1; Pou3f4; Pdx1; Rpl10; Dlk1; Dkk1; Tph1; menin; Tumour biology; Tumörbiologi;

    Abstract : Understanding signalling pathways that control pancreatic endocrine tumour (PET) development and proliferation may reveal novel targets for therapeutic intervention. The pathogenesis for sporadic and hereditary PETs, apart from mutations of the MEN1 and VHL tumour suppressor genes, is still elusive. READ MORE
