  1. 16. Liksom ett par nya ögon. Frithiof Holmgren och synsinnets problematik

    Författare :Jan-Eric Olsén; Avdelningen för idé- och lärdomshistoria; []
    Nyckelord :HUMANIORA; HUMANITIES; history of ideas; History of philosophy; vivisections; colour perception; colour-blindness; the visual organ; the human body; sensations; scientific ideals; industrial technology; Frithiof Holmgren; scientific instruments; physiological experiments; laboratory medicine; physiology; Filosofins historia; idéhistoria; History of science; Vetenskapshistoria;

    Sammanfattning : This study deals with research on the visual organ as pursued in experimental physiology during the latter half of the nineteenth-century. In the 1850's och 60's experimental physiology developed as a new, scientific discipline within the curriculum of western medicine. LÄS MER

  3. 17. Thermal Crack Risk Estimation and Material Properties of Young Concrete

    Författare :Anders Hösthagen; Jan-Erik Jonasson; Mårten Larson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermal cracking risk; young concrete; Equivalent Restraint Method; strength development; heat of hydration; creep; shrinkage; thermal dilation; modeling; field observations; Structural Engineering; Konstruktionsteknik;

    Sammanfattning : This thesis presents how to establish a theoretical model to predict risk of thermal cracking in young concrete when cast on ground or an arbitrary construction. The crack risk in young concrete is determined in two steps: 1) calculation of temperature distribution within newly cast concrete and adjacent structure; 2) calculation of stresses caused by thermal and moisture (due to self-desiccation, if drying shrinkage not included) changes in the analyzed structure.

    Sammanfattning : One of the most important aims of schooling is to give all children an equal education. Despite this, social differences continue to be reproduced in school. LÄS MER

  5. 19. Residual and critical saturation in geological storage of CO2 : results from field studies, pore-network modelling and laboratory experiments

    Författare :Ramin Moghadasi; Auli Niemi; Philip Ringrose; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Geological CO2 storage; Residual trapping; Gas remobilization; Field experiment; Numerical modelling; Pore-network modelling; Pore-scale imaging;

    Sammanfattning : Geological storage of CO2 in deep saline aquifers is a promising technology in the combat to reduce the atmospheric emissions of CO2. A critical component in this solution is the estimation of aquifer’s in situ capability to store CO2. LÄS MER

  7. 20. Development and application of spatial transcriptomics methods
