  2. 1. Field Measurements and Predictions of River Flow, Sediment Transport and Morphological Changes

    Author : Qiancheng Xie; Staffan Lundström; James Yang; J. Gunnar I. Hellström; Anders G. Andersson; Nils Ruther; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Alluvial river; Sediment transport; Morphological change; Meandering; Confluence-diffluence; River training; Field measurements; Numerical simulations; Physical model tests; Machine learning; Alluvial flod; Sedimenttransport; Morfologisk förändring; Slingrande; Konfluens-diffluens; Flodträning; Fältmätningar; Numeriska simuleringar; Fysiska modellprov; Maskininlärning; Strömningslära; Fluid Mechanics;

    Abstract : In an alluvial lowland river, sediment is transported in the form of suspended and bed loads. The fluvial process is the macroscopic view and long-term consequence of sediment movement. READ MORE

  4. 2. Morphological changes in mycobacteria

    Author : Malavika Ramesh; Leif A. Kirsebom; Anders Løbner-Olesen; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Mycobacteria; pleomorphism; dnaK_3; microaerobic condition; Morphology; oxygen deprivation; spore-like cells; Biology with specialization in Molecular Biology; Biologi med inriktning mot molekylärbiologi;

    Abstract : Morphological variations at different stages and conditions of growth has been observed frequently in various mycobacteria. Despite years of research, the molecular basis of such variations is still not clear and requires further elucidation. READ MORE

  5. 3. Modeling Genome Evolution : Creation, Change and Destruction

    Author : Mats Pettersson; Otto Berg; Paul Sniegowski; Uppsala universitet; []
    Keywords : Molecular biology; Theotretical biology; Population genetics; Stochastic modeling; Genome evolution; Molekylärbiologi;

    Abstract : Historically, evolution has been studied either by looking at morphological traits in living organisms and the fossil record, or by using bioinformatics and comparative genomics. While highly useful for deducing evolutionary history, these approaches are not particularly well suited for studying the mechanisms of evolution. READ MORE

  6. 4. Bottlenecks and blowflies : Speciation, reproduction and morphological variation in Lucilia

    Author : Ann-Britt Florin; Lisa Meffert; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; Population size; speciation; Lucilia sericata; morphological variation; Lucilia illustris; bottlenecks; Utvecklingsbiologi; Developmental biology; Utvecklingsbiologi; Animal Ecology; zooekologi;

    Abstract : This thesis attempts to improve our understanding of the role of population size for the process of speciation. First, the effect of population size on speciation is studied using several meta-analyses of published laboratory experiments. READ MORE
