    Sammanfattning : The intertidal brown alga Fucus vesiculosus L. is mainly a marine species (34 practical salinity units, psu), but the alga also grows in the sublittoral of the brackish Bothnian Sea (part of the Baltic Sea; 5 psu). LÄS MER

  4. 3. Numerical methods and multi-scale modeling for phase-field fracture - With applications in linear elastic and poro-elastic media

    Författare :Ritukesh Bharali; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; fracture; multiphysics; finite element; multiscale; desiccation; solvers; fracking; phase-field; solution techniques;

    Sammanfattning : This thesis presents novel numerical methods and a multi-scale modelling framework tailored for advancing the phase-field fracture model with applications in linear elastic and poro-elastic media. In the realm of the numerical methods, the focus lies on devising computationally efficient and robust monolithic solution techniques. LÄS MER

  5. 4. Skog, makt och människor. En miljöhistoria om svensk skog 1800-1875

    Författare :Per Eliasson; Historia; []
    Nyckelord :HUMANIORA; HUMANITIES; forest commons; science of forestry; forest crimes; desiccation; silviculture; environmental history; forests; Silviculture; forestry; forestry technology; Skogsvetenskap; skogsbruk; skogsteknik;

    Sammanfattning : The aim of this dissertation is to investigate how and why silviculture was introduced in Sweden in the nineteenth century and the consequences this introduction had during the same period. The term silviculture refers to the systematic cultivation of high forest, a method that spread from Germany at the end of the eighteenth century. LÄS MER

  7. 5. Genetically Engineered Plants: Improved stress tolerance, growth and facilitated protein purification

    Författare :Gösta Lilius; Tillämpad biokemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; glycine betaine; gene; freezing; flooding; drought; dicoteledones; desiccation; compatible solutes; cold; choline dehydrogenase; chill; CDH; betaine; betA; alkaloids anoxia; affinity purification; affinity tags; handles; hemoglobin; hypoxia; low temperatu; Biotechnology; Bioteknik;

    Sammanfattning : Heterologous genes were expressed in plants in which the overall goal was to increase the value of the final crop. Various aspects were explored and evaluated, such as improving the stress tolerance, enhancing the availability of oxygen in growing cells and producing rare proteins with increased degrees of purity.
