  1. 1. Wave energy conversion and the marine environment Colonization patterns and habitat dynamics

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Olivia Langhamer; Uppsala universitet.; Uppsala universitet.; [2009]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; artificial reefs; benthos; biodiversity; biofouling; colonization; environmental impact; fish; shellfish; Mytilus edulis; renewable energy; wave power; NATURAL SCIENCES Biology; NATURVETENSKAP Biologi; Zooekologi; Animal Ecology;

    Abstract : A wave energy park has been established on the Swedish west coast outside Lysekil and pioneer work about its interactions with the marine environment has been conducted. So far, little is known about the effects of offshore energy installations on the marine environment, and this thesis assists in minimizing environmental risks as well as in enhancing potential positive effects on the marine environment.

  2. 2. The Enemy Below - Adhesion and Friction of Ship Hull Fouling

    University dissertation from ; Chalmers tekniska högskola; Gothenburg

    Author : Dinis Oliveira; [2017]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ship resistance; in-water hull cleaning; roughness; biofouling; hull grooming; frictional resistance; adhesion strength; turbulent boundary layer; hull form factor;

    Abstract : Below the waterline, commercial ships are good targets for marine organisms to attach and proliferate, a problem commonly known as biofouling. A fouled hull means higher hydrodynamic resistance, which can result in significant fuel penalties. READ MORE

  3. 3. Enabling a Robot for Underwater Surface Cleaning

    University dissertation from Örebro : Örebro University

    Author : Houssam Albitar; Örebro universitet.; [2017]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; underwater robot; underwater cleaning; biofouling; adhesion; locomotion; stability; Reglerteknik; Automatic Control;

    Abstract : Biofouling build-up on submerged structures such as ships, petroleum and gas storage tanks, electric power plants, bridges, oil rigs etc. is a major problem that affects the surface material of the structure, the eventual hydrodynamic quality of the surface and in some cases the efficacy of cooling systems.

  4. 4. Structural and Functional Studies of De Novo Designed Peptides at Surfaces

    University dissertation from Linköping : Linköping University Electronic Press

    Author : Patrik Nygren; Linköpings universitet.; Linköpings universitet.; [2008]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biofouling; vesicles; nanoparticles; peptide; peptide design; circular dichroism; NATURAL SCIENCES Chemistry Physical chemistry; NATURVETENSKAP Kemi Fysikalisk kemi;

    Abstract : The work presented in this thesis deals with the structural and functional properties of peptides at surfaces. The interaction of peptides with surfaces is an ever so common occurrence in our every day life, from the bug squashed on the windshield of our car to the barnacle on our boat, and from the blood plasma used in the hospital to the proteins in our cells.

  5. 5. Prevention of Biofilm Formation on Silicone Rubber Materials for Outdoor High Voltage Insulators

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Sevil Atari Jabarzadeh; KTH.; [2015]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; High voltage insulator; silicone rubber; biofouling; biofilm; biocide; superhydrophobicity; self-cleaning; hierarchical roughness;

    Abstract : Microbial colonization on the surface of silicone rubber high voltage outdoor insulators often results in the formation of highly hydrated biofilm that influence the surface properties, such as surface hydrophobicity. The loss of hydrophobicity might lead to dry band formation, and, in the worst cases, flashover and failure of the insulator. READ MORE
