    Sammanfattning : The thesis comprises four independent research papers and a summary that focus on two related dimensions. The first dimension focuses on the understanding of the production of health. Particularly, the question is asked whether community's stock of social capital influence individual's health. LÄS MER

  3. 22. The hematopoietic transcription factor RUNX1 : a structural view

    Författare :Stefan Bäckström; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Molecular medicine; RUNX1; Runt domain; CBFβ; transcription factor; leukaemia; protein crystallography; anomalous diffraction; Molekylärmedicin; Molecular medicine genetics and pathology ; Molekylär medicin genetik och patologi ; molekylärbiologi; Molecular Biology;

    Sammanfattning : The malfunction of the transcriptional regulator RUNX1 is the major cause of several variants of acute human leukemias and its normal function is to regulate the development of the blood system in concert with other transcriptional co-regulators. RUNX1 belongs to a conserved family of heterodimeric transcription factors that share a conserved DNA binding domain, the Runt domain (RD), named after the first member of this group – Runt - found in Drosophila melanogaster.

  4. 23. Properties and analysis of dioxin-like compounds in marine samples from Sweden

    Författare :Kjell Lundgren; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Environmental chemistry; planar dioxin-like compound; polychlorinated dibenzofuran; polychlorinated biphenyl; polychlorinated naphthalene; alkylated polychlorinated dibenzofuran; high-performance liquid chromatography; PX-21 carbon column; biomagnification factor; biota to sediment accumulation factor; fluxes; relative retention time; mass spectrometry; relative response factor; ultra-violet spectroscopy; Miljökemi; Environmental chemistry; Miljökemi; analytisk kemi; Analytical Chemistry;

    Sammanfattning : Polychlorinated dibenzo-p-dioxins (PCDDs) and dibenzofurans (PCDFs), and dioxin-like polychlorinated biphenyls (PCBs) have been assigned toxic equivalency factors (TEFs). These compounds are today routinely analysed with sophisticated analytical techniques. LÄS MER

  5. 24. Uncertainty and sensitivity analysis applied to LWR neutronic and thermal-hydraulic calculations

    Författare :Augusto Hernandéz Solís; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sensitivity analysis; Nuclear best estimate codes; uncertainty analysis;

    Sammanfattning : The deterministic modeling of LWRs begins with the computation of energy‐collapsed and homogenizedmacroscopic cross‐sections by means of a lattice code. Once these parameters are functionalized as a functionof the reactor state variables and discretized in space, they are used as input variables by core simulators inorder to calculate the spatial distribution of the neutron flux and thus, the spatial distribution of the power.

  7. 25. Dynamics of Coinfection : Complexity and Implications

    Författare :Samia Ghersheen; Vladimir Kozlov; Uno Wennergren; Vladimir Tkachev; Åke Brännström; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Living beings are always on risk from multiple infectious agents in individual or in groups. Though multiple pathogens' interactions have widely been studied in epidemiology. Despite being well known, the co-existence of these pathogens and their coinfection remained a mystery to be uncovered. LÄS MER
