  1. 6. Deciphering HIV genetic variability and evolution by massive parallel pyrosequencing and bioinformatics

    Författare :Johanna Brodin; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : HIV-1 is a virus with a very variable genome and therefore has the ability to adapt to new environments which include escape from immune pressure and suboptimal antiretroviral treatment. Next-generation sequencing (NGS), especially ultra-deep pyrosequencing (UDPS), has enabled in-depth sequencing studies with a previously unattainable resolution. LÄS MER

  3. 7. The aquatic microbial food web and occurence of predation-resistant and potentially pathogenic bacteria, such as Francisella tularensis

    Författare :Johanna Thelaus; Agneta Andersson; Mats Forsman; Farooq Azam; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; bacteria; protozoa; ecology; predation; nutrient-availability; microbial food web; model; predation-resistance; Francisella; reservoir; biofilm formation; Freshwater ecology; Limnisk ekologi;

    Sammanfattning : All natural aquatic systems harbour a vast variety of microorganisms. In the aquatic microbial food web, the larger microorganisms (i.e. protozoa) feed on the smaller microorganisms (i. LÄS MER

  4. 8. Functional characterization of cellulose and chitin synthase genes in Oomycetes

    Författare :Johanna Fugelstad; Vincent Bulone; Carol Munro; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; cellulose biosynthesis; chitin biosynthesis; cellulose synthase gene; chitin synthase gene; Oomycetes; Phytophthora infestans; Saprolegnia monoica; pleckstrin homology domain; Microbiology; Mikrobiologi;

    Sammanfattning : Some species of Oomycetes are well studied pathogens that cause considerable economical losses in the agriculture and aquaculture industries. Currently, there are no chemicals available that are environmentally friendly and at the same time efficient Oomycete inhibitors. LÄS MER

  5. 9. Wicked Problems in Engineering Education : Preparing Future Engineers to Work for Sustainability

    Författare :Johanna Lönngren; Magdalena Svanström; Åke Ingerman; Tom Adawi; John Holmberg; Marie Paretti; Chalmers tekniska högskola; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; wicked problem; engineering education; sustainability; phenomenography; assessment; rubric; design-based research; action research; perspective shift; ill-structured problems; problem-solving; didactics of natural science; naturvetenskapens didaktik;

    Sammanfattning : Most engineering education today does not adequately prepare students to contribute to sustainability. For example, engineering students often do not learn how to address complex and ill-structured sustainability problems that involve different stakeholders, value conflicts,and uncertainty; such problems are also called wicked problems.

  7. 10. By foot at ease : environmental affordances for wellbeing in walking

    Författare :Thomas Höjemo; Beatriz Fedrizzi; Anna-Johanna Klasander; Universidade Federal do Rio Grande do Sul; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HUMANIORA; HUMANITIES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Sammanfattning : Walking has been shown to provide benefits for our health and also for the environment. Research has also shown that if the built environment is adapted for pedestrians, people walk more. However, there is a lack of qualitative research in architecture and urban design on walking at the micro (streetscape) scale. LÄS MER
