  1. 21. Endosymbiosis of Frankia cluster-2

    Författare :Fede Berckx; Katharina Pawlowski; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; root nodule endosymbiosis; Frankia; Datisca glomerata; nitrogen fixation; actinorhizal; peptidoglycan; RT-qPCR;

    Sammanfattning : Actinobacteria of the genus Frankia engage in root endosymbiosis with actinorhizal plants belonging to the Fagales, Cucurbitales and Rosales. The genus Frankia consists of four different clades. Strains belonging to cluster-1, -2, and -3 exhibit host-specificity which plants they can nodulate, while cluster-4 strains do not engage in symbiosis. LÄS MER

  3. 22. Synthesis of Spiro-bicyclo[2.2.2]Octane Derivatives Towards the Development of Paclitaxel Mimetics

    Författare :Viveca Thornqvist; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Kemi; Organic chemistry; Organisk kemi; Chemistry; Natural science; paclitaxel; spiro; indium; Naturvetenskap; bicyclo[2.2.2]octane; allylation; paclitaxel mimetic;

    Sammanfattning : Many of the drugs that are developed in the pharmaceutical industry have their origin in natural products. Paclitaxel, the active substance of the medicine Taxol, was found in the bark of the Pacific yew tree (Taxus brevifolia). LÄS MER

  4. 23. Developing Data-Driven Models for Understanding Human Motion

    Författare :Wenjie Yin; Mårten Björkman; Danica Kragic; Anders Heyden; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Datalogi; Computer Science;

    Sammanfattning : Humans are the primary subjects of interest in the realm of computer vision. Specifically, perceiving, generating, and understanding human activities have long been a core pursuit of machine intelligence. LÄS MER

  5. 24. Preservation of Marine Reptile Soft Parts: Reconstructing the Life and Death of Ancient Leviathans

    Författare :Randolph De La Garza; Berggrundsgeologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Molecular paleontology; Taphonomy; Soft-tissues; Lagerstätten; Skin; Sea Turtle; Ichthyosaur; Fur Formation; Posidonia Shale; Paleobiology; Marine Reptiles;

    Sammanfattning : Marine reptiles constitute a diverse group of secondarily aquatic tetrapods that have inhabited the world’s oceans for the greater part of the last 250 million years. While certain large-scale anatomical changes have been observed through progressive alterations of their skeletal morphology (e.g. LÄS MER

  7. 25. Dynamics of the interstellar matter in galaxies : isolated barred spiral galaxies : cloud formation processes

    Författare :Kristen Helmuth; John Beckman; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Astronomy; Astronomi; Astronomy; astronomi;

    Sammanfattning : The dynamical components of six isolated barred spiral (SB) galaxies are investigated. No evidence is found supporting the hypothesis of a low amount of dark matter being characteristic of SB galaxies. The presence of companion galaxies is found to correlate with an increased statistical spread in the neutral hydrogen (HI) extent. LÄS MER
