  1. 1. Bioactive Compounds in the Chemical Defence of Marine Sponges : Structure-Activity Relationships and Pharmacological Targets

    Författare :Erik Hedner; Lars Bohlin; Per R Jonsson; Raffaele Riccio; Uppsala universitet; []
    Nyckelord :Pharmacognosy; 5-hydroxytryptamine; agelasine; agelasimine; antibacterial; antifouling; barettin; bromobenzisoxazolone barettin; cytotoxic; marine; secondary metabolite; sponge; Farmakognosi; Agelas; Geodia barretti;

    Sammanfattning : Marine invertebrates, in particular sponges, represent a source of a wide range of secondary metabolites, many of which have been attributed various defensive capabilities against environmental stress factors. In this thesis sponge-derived low-molecular peptide-like compounds and associated analogs are investigated for bioactivity and pharmacological targets. LÄS MER

  3. 2. Primärvårdens arbete med sjukskrivna – patientmötet, bedömningar och samverkan

    Författare :Marine Sturesson; Birgitta Bernspång; Annie Hansen Falkdal; Curt Edlund; Kristina Alexanderson; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Primary health care; Sickness certification; Work ability; Health care encounters; Occupational Therapy; Return to work;

    Sammanfattning : The ability to work can be reduced if a person has health problems which may lead to periods of sick leave. In Sweden sickness certification is issued by physicians. Many general practitioners (GPs) find sickness certification to be problematic. Some studies indicate that collaboration with other health care professions could be beneficial. LÄS MER

  4. 3. On the processing and properties of cellulose-containing polymeric materials

    Författare :Ruth Arino Marine; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; dispersion; extrusion; injection moulding; ionic liquids; compounding; ethylene-acrylic acid copolymer; gels; cellulose fibres; rheological properties;

    Sammanfattning : Cellulose fibres have properties such as renewability, biodegradability, very good availability and low cost that make them very attractive as a reinforcement for thermoplastic polymers. Other more specific favourable properties are low density, high specific stiffness, low abrasive nature and their potential for modification. LÄS MER

  5. 4. On the processing and properties of cellulose-containing polymeric materials

    Författare :Ruth Arino Marine; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; rheological properties; compounding; dispersion; ionic liquids; ethylene-acrylic acid copolymer; cellulose fibres; gels;

    Sammanfattning : ABSTRACTCellulose fibres have properties that make them very attractive as a reinforcement for thermoplastic polymers. Renewability, biodegradability, very good availability and low cost are some general advantages. LÄS MER

  7. 5. Functional diversity of zooplankton in marine food webs : Integrating DNA metabarcoding and network modeling

    Författare :Andreas Novotny; Monika Winder; Catherine Legrand; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Plankton; Food-Webs; DNA metabarcoding; Marine; Baltic Sea; Marine Ecology; marin ekologi;

    Sammanfattning : The oceans are important regulators of the Earth’s climate system by sequestering carbon from the atmosphere taken up by primary producers. Zooplankton, including protozoans and metazoans of different phyla and size classes, occupies several trophic niches and regulates energy flow between primary producers and fish. LÄS MER
