  1. 31. Random walk boundaries: their entropies and connections with Hecke pairs

    Författare :Hanna Oppelmayer; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Poisson boundary; Hecke pairs; Non-singular dynamical systems; Schlichting completion; random walks on groups; non-monotone sequences of $ sigma$-algebras; Furstenberg entropy;

    Sammanfattning : We present three papers in non-singular dynamics concerning boundaries of random walks on locally compact, second countable groups. One common theme is entropy. Paper II and III are concerned with boundary entropy spectra, while Paper I studies topological properties of entropy. LÄS MER

  3. 32. The breast cancer microenvironment and cancer cell secretion - specific effects on cancer progression and subtypes of cancer cells

    Författare :Emma Persson; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Breast cancer; cancer microenvironment; secretion; hypoxia;

    Sammanfattning : Breast cancer is the cancer form responsible for the most cancer-related deaths among women worldwide, and novel targeted therapies are highly needed. The tumor microenvironment consists of several components, including different cell types, extracellular matrix, oxygen and nutrient gradients and soluble factors that plays a key role in cancer progression.

  4. 33. Long-Term Functional Psychosis : Epidemiology in Two Different Counties in Sweden

    Författare :Birgitta Widerlöv; Lars von Knorring; Jerker Hetta; Uppsala universitet; []
    Nyckelord :Psychiatry; epidemiology; functional psychosis; schizophrenia; prevalence; rural-urban gradient; comparative study; antipsychotic drugs; diagnostic criteria; mortality; Psykiatri;

    Sammanfattning : This thesis is based on two independent studies, the first in Stockholm County (index year 1984; n=302), and the second, a replication and validation study, in Uppsala County (index year 1991; n=455).The general aim was to study all individuals with Long-term Functional Psychosis (LFP) within the two counties of Sweden from an epidemiological perspective and to perform specific studies on a subgroup of individuals with schizophrenia.

    Sammanfattning : Being severely burned is a traumatic life event that affects the victim both physically and psychologically. Recovery can be a long process that is dependent in part upon psychological factors, but research in this area is still quite limited. LÄS MER

  7. 35. Large cerebral artery occlusion and recanalisation in stroke patients treated with intravenous thrombolysis : clinical and radiological markers and their clinical relevance

    Författare :Tatiana Kharitonova; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Large cerebral artery occlusion accounts for 40-46% of ischemic strokes. These strokes are characterized by extensive neurological deficit, poor functional outcome, and increased mortality (up to 40-80% in the most severe clinical syndromes). LÄS MER
