  2. 1. A radical view of haemoglobin - protein engineering and characterisation

    Author : Marie Grey; Tillämpad biokemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; His-Gln tagging; protein purification; blood substitutes; radical scavenging; superoxide dismutase; E. coli; diglobin; Haemoglobin; protein engineering; aqueous two-phase systems; hydrophobic interaction chromatography;

    Abstract : In recent years shortages of donated blood have become a growing problem for health care systems world-wide. Blood substitutes based on human haemoglobin (Hb) could potentially ameliorate this situation. However, clinical trials have indicated problems due to e.g. READ MORE

  4. 2. Structures and Properties of Ferroelectric Liquid Crystal Displays

    Author : Marek Matuszczyk; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; smectic; displays; dielectric anisotropy and biaxiality; surface-stabilized structure; dielectric; paraelectric; liquid crystal alignment; electroclinic effect; grey scale; polarization; multiplexing; liquid crystal LC ; orthogonal and tilted phases; chirality; aligning layer; ferroelectric; polyimide; rubbing; light valves and modulators; SSFLC;

    Abstract : Liquid crystals have unique physical properties as they combine the features of solids and liquids. In thermotropic liquid crystals the degree of order varies with temperature resulting in an appearance of intermediate phases. READ MORE

  5. 3. The conflict between Grey seals (Halichoerus grypus) and the Baltic coastal fisheries : new methods for the assessment and reduction of catch losses and gear damage

    Author : Arne Fjälling; Mats Amundin; Sverre Sjölander; Anders Fernö; Linköpings universitet; []
    Keywords : Ecology; Grey seals; Baltic coastal fisheries; Ekologi; NATURAL SCIENCES; NATURVETENSKAP;

    Abstract : There is a problematic interaction going on between grey seals and the small scale coastal fisheries in the Baltic. A large number of seals are by-caught and drowned each year, and the viability of the fishery is threatened by catch losses caused by the seals. READ MORE

  6. 4. Data-driven Ship Performance Models - - Emphasis on Energy Efficiency and Fatigue Safety

    Author : Xiao Lang; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; semi-empirical; energy efficiency; fatigue assessment; grey-box; full-scale measurements; speed-power relationship; added resistance due to waves; ship performance; machine learning;

    Abstract : Due to digitalization in the maritime industry, a huge amount of ship operation-related data has been collected. The main objective of this thesis is to exploit machine learning/big data analytics to build data-driven ship performance models, focusing on speed-power relationship modeling, and fatigue accumulation assessment during a ship’s operation at sea.

  7. 5. Assessment of dietary patterns and prey consumption of marine mammals: Grey seals (Halichoerus grypus) in the Baltic Sea

    Author : Karl Lundström; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; grey seal; Halichoerus grypus; Baltic Sea; diet; predation; fish; consumption; fatty acid signature analysis; bioenergetics; foraging ecology;

    Abstract : The Baltic Sea has been severely affected by pollution and resource overexploitation during the last centuries. The grey seal (Halichoerus grypus) is a good example of how a species can be affected by such changes. READ MORE
