  2. 26. Membrane Filtration of Lignocellulosic Materials: In situ Monitoring of Membrane Fouling Using Fluid Dynamic Gauging

    Author : Kenneth Gacutno Arandia; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wood components; Membrane fouling; Fluid dynamic gauging; Cross-flow filtration;

    Abstract : The transition of process industries from utilizing fossil-based resources to bio-based ones necessitates energy-efficient and selective operations. One practical operation that can be employed for processing streams containing lignocellulosic biomass, such as forest and agricultural residues, is membrane separation. READ MORE

  4. 27. Molecular biology of barnacle Balanus improvisus settlement

    Author : Anna Abramova; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; barnacles; settlement; transcriptomics; ecdysone cascade; chemosensory receptors; waterborne pheromones;

    Abstract : The aim of this thesis was to investigate molecular mechanisms of various aspects of barnacle settlement, using the acorn barnacle Balanus improvisus. This barnacle is a common fouling species and a model organism for studies in settlement biology, in particular in relation to antifouling research. READ MORE

  5. 28. Bioaccumulation and biological effects of organic contaminants in Icelandic coastal waters

    Author : Halldóra Skarphéđinsdóttir; Åke Granmo; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Miljögifter; Marine Ecotoxicology; marin ekotoxikologi;

    Abstract : In this thesis, studies on organic contamination from both diffuse and point sources in Icelandic waters are presented. The aim was to investigate bioaccumulation and biological effects of the contaminants or biomarkers, and their applicability in environmental marine coastal monitoring, especially in areas with moderate or low levels of contamination such as Iceland.

  6. 29. Imidazole containing polymers complexed with Cu2+ and Zn2+

    Author : Markus Andersson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; vibrational spectroscopy; far-FTIR; EPR; cross-linking; DSC; Coordinating polymer; imidazole; mid-FTIR; metal ion;

    Abstract : An enormous problem for the shipping industry is fouling of marine organisms such as algae andbarnacles on the boat hull. The negative consequences for the society are both economical as well asenvironmental. To prevent fouling in general, biocides are typically incorporated directly into the paint. READ MORE

  7. 30. Prevention of bacterial colonization in hospital-acquired infections using electrically conducting polymers

    Author : Salvador Gomez-Carretero; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Biofilms are bacterial assemblies developed as response to adverse environmental conditions and external threats. Within a biofilm, a complex and highly regulated internal architecture is developed, resulting in a network of interconnected microniches. READ MORE
