  2. 1. Non-Azeotropic Mixtures as Working Fluids in Heat Pumps: A theoretical and experimental study

    Author : Marine Högberg; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HCFC123; HCFC124a; HCFC22; performance comparison; COP; non-azeotropic mixture; capacity; sensitivity analysis; HFC152a; heat pump; CFC114; ethyl chloride; experimental study; HCFC142b; two-stage cycle;

    Abstract : Due to the fact that CFC (Chloro-Fluoro-Carbon) fluids will be forbidden as working fluids in heat pumps for environmental reasons, there is an urgent need for alternatives. As one alternative type of fluid, non-azeotropic mixtures have been suggested. This thesis deals with such mixtures. READ MORE

  4. 2. On the processing and properties of cellulose-containing polymeric materials

    Author : Ruth Arino Marine; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; dispersion; extrusion; injection moulding; ionic liquids; compounding; ethylene-acrylic acid copolymer; gels; cellulose fibres; rheological properties;

    Abstract : Cellulose fibres have properties such as renewability, biodegradability, very good availability and low cost that make them very attractive as a reinforcement for thermoplastic polymers. Other more specific favourable properties are low density, high specific stiffness, low abrasive nature and their potential for modification. READ MORE

  5. 3. On the processing and properties of cellulose-containing polymeric materials

    Author : Ruth Arino Marine; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; rheological properties; compounding; dispersion; ionic liquids; ethylene-acrylic acid copolymer; cellulose fibres; gels;

    Abstract : ABSTRACTCellulose fibres have properties that make them very attractive as a reinforcement for thermoplastic polymers. Renewability, biodegradability, very good availability and low cost are some general advantages. READ MORE

  6. 4. Foraging behaviour in benthivorous fish

    Author : Marika Stenberg; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Marinbiologi; resource assessment; giving-up densities; predation risk; foraging behaviour; limnology; marine biology; Ekologi; akvatisk ekologi; limnologi; group foraging; benthivorous fish; aquatic ecology; Hydrobiology; Ecology;

    Abstract : The foraging ability of an organism is essential since it affects various traits, e.g. growth, reproduction effort, social status and, ultimately, fitness. READ MORE

  7. 5. Trophic interactions and behaviour : Studies relevant to a Baltic Sea biomanipulation

    Author : Per B. Holliland; Sture Hansson; Elena Gorokhova; Peter Tiselius; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; zooplankton; non-indigenous species; selectivity; food web; rearing environment; fish stocking; Sander lucioperca; diel vertical migration; ontogeny; ovigerous; Marine Ecology; marin ekologi;

    Abstract : The main theme of this thesis is the interactions of animals with the environment and each other. The thesis was written within the framework of a biomanipulation project “Pikeperch in Himmerfjärden”. READ MORE
