  2. 1. Microstructure of spray dried particles at different scales of drying

    Author : Marine Nuzzo; Livsmedelsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; microstructure; morphology; confocal Raman microscopy; phase segregation; spray drying;

    Abstract : Spray drying is a preferred method to produce dry powder of thermally sensitive materials such as food and pharmaceuticals. Drying conditions and formulation determine primary properties such as morphology and composition that finally provide functionality such as dissolution, encapsulation and flowability. READ MORE

  4. 2. 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

  5. 3. Environmental actions on concrete exposed in marine and road environments and its response - Consequences for the initiation of chloride induced reinforcement corrosion

    Author : Anders Lindvall; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; corrosion; de-icing salt; road conditions; marine conditions; service life predictions; reinforcement; chloride; concrete; moisture conditions; environmental actions;

    Abstract : The object of the study presented here has been to describe, further explain and model the influence of the exposure conditions on reinforced concrete structures and the consequences on their expected service life. The focus has been on investigating and quantifying the exposure conditions for structures in marine and road conditions exposed to chloride ions. READ MORE

  6. 4. Marine seaweed invasions : Impacts and biotic resistance in native ecosystems

    Author : Josefin Sagerman; Sofia Wikström; Fransisco Arenas; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Plant invasion; exotic species; generalist herbivores; plant-herbivore interactions; enemy-release hypothesis; ecosystem function; marin ekotoxikologi; Marine Ecotoxicology;

    Abstract : Marine seaweeds constitute one of the most productive plant systems known on Earth and a rich fauna including juvenile fish and crustaceans is dependent on the habitats they form. Human influence on marine costal ecosystems has resulted in large scale changes to the abundance and distribution of species, where species introductions constitute an obvious part. READ MORE

  7. 5. Searching for sustainable aquaculture governance : A focus on ambitions and experience

    Author : Ola Luthman; Rickard Lalander; Fred Saunders; Max Troell; Megan Bailey; Södertörns högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Aquaculture; policy; environmental governance; Social-Ecological Systems; Environmental Studies; Miljövetenskapliga studier; Östersjö- och Östeuropaforskning; Baltic and East European studies;

    Abstract : Aquaculture is one of the most diverse food-producing industries and is suggested as a key solution to a growing global food demand. It has been argued that aquaculture has the potential to expand sustainably in most parts of the world, especially in the EU where consumption far out weighs production. READ MORE
