    Sammanfattning : The present research was focused on the phytochemical research of Bolivian plants; a) two medicinal ones Aniba canelilla and Iryanthera juruensis, both plants showed to have compounds with biological activity in different fields. Even though Aniba canelilla was studied before, new compounds were identified in this investigation. LÄS MER

  3. 27. Plant Major Intrinsic Proteins - natural variation and evolution

    Författare :Jonas Danielson; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MIP; aquaporin; plant; natural variation; evolution; Arabidopsis; Physcomitrella patens; NIP; XIP;

    Sammanfattning : Major Intrinsic Proteins (MIPs, also called Aquaporins, AQPs) are channel forming membrane proteins. Although initially functionally characterized and named after their water channeling property in human red blood cells, it has become increasingly evident that MIPs are present in all types of organisms and transport a variety of small, uncharged molecules besides water.

  4. 28. Tecken av betydelse : En studie av dialog i ett multimodalt, teckenspråkigt tvåspråkigt NO-klassrum

    Författare :Camilla Lindahl; Bengt-Olov Molander; Inger Lindberg; Anders Jakobsson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Science education; multilingualism; sign language; multimodality; social semiotics; dialogic teaching; translanguaging; scaffolding; Naturvetenskapsämnenas didaktik; flerspråkighet; teckenspråk; multimodalitet; socialsemiotik; dialogisk undervisning; translanguaging; stöttning; Didactics; didaktik;

    Sammanfattning : Ett gemensamt meningsskapande i skolans naturvetenskapliga klassrum förutsätter en interaktion som i allt högre grad kommer att präglas av ett naturvetenskapligt språkbruk. Utvecklingen av ett naturvetenskapligt ämnesspråk innebär ofta en stor utmaning för flerspråkiga elever som lär sig naturvetenskap på sitt andraspråk och vars behov av stöttning därför är särskilt stort.

  5. 29. Stewardship in Swedish Baltic small-scale fisheries : A study on the social-ecological dynamics of local resource use

    Författare :Emma Björkvik; Wiebren J. Boonstra; Thorsten Blenckner; Jonas Hentati-Sundberg; McCay Bonnie; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; case study research; local ecological knowledge; marine environments; practice; semi-structured interviews; small-scale fisheries social-ecological system; social-ecological traps; structuration theory; traditional ecological knowledge; Sustainability Science; vetenskap om hållbar utveckling;

    Sammanfattning : Sustainability scholars frequently advocate for stewardship as a strategy to foster sustainable development. Stewardship broadly refers to the wise and responsible use of nature, and is considered necessary to ensure the long-term wellbeing of humans and that of life in general. LÄS MER

  7. 30. Home for future Earth lovers : Foundations of nature-connecting habitats for children
