  1. 1. Low biocide emission antifouling based on a novel route of barnacle intoxication

    University dissertation from Göteborg : University of Gothenburg

    Author : Emiliano Pinori; Göteborgs universitet.; Gothenburg University.; [2013]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; antifouling; Barnacles; ivermectin; low biocide emission; marine fouling; marine paint; ISO 15181; ToF-SIMS;

    Abstract : Marine biofouling can be defined as the colonization of man-made surfaces in seawater by microscopic and macroscopic organisms. This phenomenon can result in great loss of function and effectiveness both for cruising ships and for static constructions. READ MORE

  2. 2. Impacts of Antifouling Compounds on Photosynthesis, Community Tolerance and psbA Genes in Marine Periphyton

    University dissertation from Göteborg : University of Gothenburg

    Author : Karl Martin Eriksson; Göteborgs universitet.; Gothenburg University.; [2008]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; PICT; antifouling; periphyton; photosynthesis; D1; psbA; tolerance; resistance;

    Abstract : Toxicants can act as selective pressures in the environment, eliminating sensitive genotypes or species and favouring tolerant ones. Such toxicant-induced selection can be detected in natura... READ MORE

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

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Erik Hedner; Uppsala universitet.; [2007]
    Keywords : Pharmacognosy; 5-hydroxytryptamine; agelasine; agelasimine; antibacterial; antifouling; barettin; bromobenzisoxazolone barettin; cytotoxic; marine; secondary metabolite; sponge; Farmakognosi; Agelas; Geodia barretti;

    Abstract : 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. READ MORE

  4. 4. Studies of fish responses to the antifoulant medetomidine

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Anna Lennquist; Göteborgs universitet.; Gothenburg University.; [2010]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; antifouling; fish; medetomidine; ecotoxicology; biomarker;

    Abstract : ABSTRACT Growth of marine organisms, fouling, on man-made constructions submerged in the water is regarded as a major problem. For vessels, fouling increases drag and thereby fuel consumption, wherefore antifouling paints are used. Traditionally, they contain toxic compounds, and several of these have unwanted effects in the environment. READ MORE

  5. 5. Pharmacological agents targeted against barnacles as lead molecules in new antfouling technologies

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Mia Dahlström; Göteborgs universitet.; Gothenburg University.; [2004]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; cypris larvae; settlement assay; adrenoceptor compounds; imidazoline binding site ligands; wettability; surface adsorption; ToF-SIMS; barnacle field recruitment; antifouling; release; HPLC; ellipsometry;
