  2. 1. Environmental influences on the behavioural ecology of juvenile salmonids – the importance of rearing density

    Author : Sofia Brockmark; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; rearing density; structural complexity; familiarity; antipredator response; limited attention; social status; growth rate; smolt status; fin erosion; post-release performance; hatchery supplementation; brown trout; Atlantic salmon;

    Abstract : Background and aims: Early environmental conditions are known to influence the phenotypic development of animals, including behavioural alterations. The overall aim of this thesis is to investigate the effects of density, social stability and structural complexity on growth, behaviour, and survival in the wild, using juvenile brown trout (Salmo trutta) and Atlantic salmon (Salmo salar) as model species.

  4. 2. Tribological behaviour of HVAF-sprayed WC-based coatings: : Role of process variables and binder chemistry

    Author : Kaveh Torkashvand; Mohit Kumar Gupta; Shrikant V. Joshi; Högskolan Väst; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Tribological Behaviour; HVAF; WC-Based Coatings; Process Variables; Binder Chemistry; Tribologisk Prestanda; HVAF; WC-baserade Beläggningar; Parametervariabler; Bindemedelskemi; Production Technology; Produktionsteknik;

    Abstract : Tungsten carbide (WC) based metallic matrix coatings sprayed using high velocity air fuel (HVAF) technique have attracted increasing attention as they show excellent tribological performance in various wear conditions. In the HVAF method, particles’ in-flight temperature and velocity can be influenced by the process variables including nozzle configuration as well as feedstock particle size range. READ MORE

  5. 3. Biochemical characterisation of landfill leachate toxicity in fish

    Author : Maria Linderoth; Lennart Balk; Ulf Rannug; Cinta Porte Visa; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; landfill leachate; endocrine disruption; fish; Environmental toxicology; Miljötoxikologi;

    Abstract : Deposition remains the most common form of waste disposal in many parts of the world. As a terminus of the products consumed in our society a landfill may contain virtually all sorts of man-made chemicals. Despite this, the harmfulness of landfill leachate has not been extensively evaluated in feral organisms in the environment. READ MORE

  6. 4. Environmental Monitoring of Refuse Dump Leachate Toxicity in Fish

    Author : Erik Noaksson; Lennart Balk; Louis J. Guillette Jr; Stockholms universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Fiskar; miljögifter; Toxicology; Toxikologi;

    Abstract : The global economy is driven by the consumption of goods and materials. Used products are often deposited on refuse dumps, making them potential point sources for all man-made chemicals. Water soaking through landfill waste results in a wastewater termed leachate. READ MORE
