  1. 1. Proterozoic crustal evolution in southcentral Fennoscandia

    Författare :Karin Appelquist; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Transscandinavian Igneous Belt; TIB; Eastern Segment; Habo Volcanic Suite; Malmbäck Formation; U-Pb zircon ion probe dating; Nd isotopes; geochemistry; Hallandian; Danopolonian;

    Sammanfattning : The Transscandinavian Igneous Belt (TIB) and the Eastern Segment of the Southwest Scandinavian Domain reflect advanced stages of continental growth within the Fennoscandian Shield. The relationship between the two units is not clear, mainly because N-S trending shear zones of the Protogine Zone transect the border zone. LÄS MER

  3. 2. Spark plasma sintering and deformation behaviour of Titanium and Titanium/TiB2Spark plasma sintering and deformation behaviour of Titanium and Titanium/TiB2 composites

    Författare :Mirva Eriksson; Zhijian Shen; Guocai Chai; Stockholms universitet; []
    Nyckelord :materialvetenskap; Materials Science;

    Sammanfattning : Titanium has been used as a model substance to study how it behaves in a SPS apparatus when heating rate and/or pressure were varied during the sintering and deformation process. The sintering and deformation of Ti in SPS were compared with that occurring in the conventional hot pressing (HP) in order to reveal if there are any positive effects added by the use of SPS.

  4. 3. The role of sleep and shift work in dementia and cognitive aging : an epidemiological approach

    Författare :Kathleen Bokenberger; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Dementia is a syndrome that afflicts older persons and is characterized by progressive deterioration in memory and other cognitive functions, behavior, and the ability to perform day-to-day activities. Older adults, and even more so those suffering from dementia, often experience disturbances in the sleep-wake cycle. LÄS MER

  5. 4. Immunotherapy for pancreatic cancer

    Författare :Qingda Meng; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Patients with pancreatic cancer have a short life expectancy, and only 20% of the patients diagnosed with pancreatic cancer can undergo surgery. Chemotherapy does not work well: Gemcitabine is the standard regimen with a 5-year survival rate of 1%–4% and a median survival time of 4-6 months; FOLFIRINOX chemotherapy regimen using four drugs was found to be more effective (median survival 11 months), but with substantial side effects.

  7. 5. Hormonal regulation of the primate uterus : effects of hormone treatment and lifestyle intervention

    Författare :Mariana Hulchiy; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :endometrium;

    Sammanfattning : The uterus is a major hormone-responsive reproductive organ in primates. Hormones promote their effect via different pathways. Receptors involved in steroid hormone, thyroid hormone and insulin signaling have been found in the endometrium. LÄS MER
