  1. 1. 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.

  3. 2. Imaging of nucleocytoplasmic transcription factor dynamics in yeast

    Författare :Kristofer Bodvard; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; transcription factor; single-cell; yeast; image analysis; Saccharomyces cerevisiae; light stress; Fluorescence microscopy; signalling;

    Sammanfattning : Fluorescence microscopy has proven to be an invaluable tool in identifying and understanding cell signalling, intracellular spatial and temporal dynamics, and cell-to-cell variability. This thesis focuses on imaging of nucleocytoplasmic transcription factor dynamics at the single cell level in yeast. LÄS MER

  4. 3. Spatial Variation in Near-Ground Radiation and Low Temperature - Interactions with Forest Vegetation

    Författare :Kristina Blennow; Institutionen för naturgeografi och ekosystemvetenskap; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; light interception; hemispherical photograph; growth; forest fragmentation; fluorescence; cold-induced photoinhibition; GIS; view factor; radiative cooling; frost protection; agro-climatic mapping; forest clear-cut; local climate; Microclimate; Physical geography; geomorphology; pedology; cartography; climatology; Fysisk geografi; geomorfologi; marklära; kartografi; klimatologi;

    Sammanfattning : Low temperature has a large impact on the survival and distribution of plants. Interactive effects with high irradiance lead to cold-induced photoinhibition, which may impact on the establishment and growth of tree seedlings. LÄS MER

  5. 4. Svensk och finsk upphinnartillväxt : Faktorpris- och produktivitetsutjämning mellan Finland och Sverige 1950-2000

    Författare :Jonatan Svanlund; Magnus Lindmark; Christer Lundh; Umeå universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Economic history; Sweden; Finland; Convergence; Catch-Up Growth; Productivty; Factor Prices; Wage moderation; Shift-Share analysis; growth accounting; neo-classical growth theory; Economic history; Ekonomisk historia; ekonomisk historia; Economic History;

    Sammanfattning : The aim of this thesis is to gain improved understanding of the income convergence between Finland and Sweden 1950-2000 with a focus on catch-up growth, wage formation, productivity growth, migration and structural change in a setting of structural and institutional differences on the factor markets. Earlier studies of Finnish and Swedish convergence has overlooked the international perspective and therefore missed the general European – US convergence during the period. LÄS MER

  7. 5. A Multi Sensor System for a Human Activities Space : Aspects of Planning and Quality Measurement

    Författare :Jiandan Chen; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 3D Reconstruction; Iso-disparity Surfaces; Depth Reconstruction Uncertainty; Uncertainty Analysis; Dither; Sensor Placement; Multi Stereo View; Image Quality; Human Factor;

    Sammanfattning : In our aging society, the design and implementation of a high-performance autonomous distributed vision information system for autonomous physical services become ever more important. In line with this development, the proposed Intelligent Vision Agent System, IVAS, is able to automatically detect and identify a target for a specific task by surveying a human activities space.
