  1. 1. Morphometric differentiation in Papaver radicatum (Papaveraceae) : Geographic pattern and significance for refugial survival theory

    Författare :Eva Selin; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ecology; Capsule morphology; Geographic pattern; Leaf morphology; Morphometric variation; Papaver radicatum; Refugial survival; Seed shape; Ekologi; Terrestrial; freshwater and marine ecology; Terrestisk; limnisk och marin ekologi; ekologisk botanik; Ecological Botany;

    Sammanfattning : The morphometric pattern of variation among and within Scandinavian populations of the alpine species Papaver radicatum was studied. Results from analyses (including multivariate techniques) of capsule and leaf traits of wild-collected and cultivated plants as well as wild-collected seeds show correlated patterns of variation in capsule traits and partly corresponding patterns of variation between capsule and seed traits.

  3. 2. Digital holography and image processing methods for applications in biophysics

    Författare :Hanqing Zhang; Magnus Andersson; Krister Wiklund; Wählby Carolina; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Digital holographic microscopy; image processing; image reconstruction; bacterial adhesion; cell morphology; algorithm development; software design; quantitative measurement; microfluidics; multidisciplinary research; signalbehandling; Signal Processing; teknisk fysik med inriktningen mikrosystemteknik; engineering science with specialization in microsystems technology;

    Sammanfattning : Understanding dynamic mechanisms, morphology and behavior of bacteria are important to develop new therapeutics to cure diseases. For example, bacterial adhesion mechanisms are prerequisites for initiation of infections and for several bacterial strains this adhesion process is mediated by adhesive surface organelles, also known as fimbriae.

  4. 3. Arthroscopy in the upper extremity

    Författare :Lars Adolfsson; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : This stndy comprising six separate papers, is concerned with the techniques of, and bevaluation of arthroscopy as a diagnostic and therapeutic tool in different pathologic conditions in the upper extremity.Arthroscopy proved to increase diagnostic accuracy in 177 examined patients with anterior shoulder instability or shoulder pain.

  5. 4. Nanofeatures of Biomaterials and their Impact on the Inflammatory Response

    Författare :Shiuli Pujari-Palmer; Marjam Ott; Håkan Engqvist; Matteo Santin; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Nanofeatures; alumina; hydroxyapatite; inflammation; Teknisk fysik med inriktning mot materialvetenskap; Engineering Science with specialization in Materials Science;

    Sammanfattning : Nanomaterials offer an advantage over traditional biomaterials since cells naturally communicate via nanoscale interactions. The extracellular matrix, for example, modulates adhesion and cellular functions via nanoscale features. LÄS MER

  7. 5. Ultrastructural and systematic studies of cecidomyiidae (Diptera)

    Författare :Ruben Tastás-Duque; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Gallmyggor; tvåvingar; cecidomyiidae; diptera;

    Sammanfattning : Examination of the abdomen of the adult female and the head capsule of the mature larva indicates the grat utility of the Scanning Electron Microscope (SEM) in examining structures when searching for useful characters to deal with the taxonomy and phylogeny of gall midges (Diptera: Cecidomyiidae). Some of the structures found represent adaptations of limited value for phylogenetic considerations at higher levels. LÄS MER
