  2. 1. Quality of Frozen Rainbow Trout. Effects of different freezing and thawing treatments

    Author : Katarina Nilsson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; membrane disintegration; liquid loss; centrifuged tissue fluid; fish; lysosomal enzyme; frozen storage; glazing; freezing; sensory quality; rainbow trout; thawing;

    Abstract : The effects of different freezing, frozen storage and thawing treatments on the muscle tissue of farmed rainbow trout (Oncorhychus mykiss) were studied. Biochemical measurements were correlated to sensory estimated quality changes. The freezing process affects the proteins, the lipid fractions and the membrane structures in the fish muscle.

  4. 2. Artificial Ground Freezingin Clayey Soils : Laboratory and Field Studies of Deformations During Thawing at the Bothnia Line

    Author : Teddy Johansson; Staffan Hintze; Håkan Stille; Sven Knutsson; Kauko Kujala; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Artificial ground freezing; AGF; thaw deformation; deformation; thawing; frost heaving; Bothnia Line.; Artificiell markfrysning; artificiell jord- och bergfrysning; AGF; tiningsdeformation; deformation; tining; tjälhävning; Botniabanan; Geoengineering; Geoteknik;

    Abstract : Artificial ground freezing as a method to temporarily stabilize and create hydraulic sealing in urban as well as in rural areas has been used in a number of Swedish construction projects, particularly during the last decade. One problem with the freezing of soil and rock is that fine-grained clayey types of soils have showed a tendency to under certain circumstances, during the thawing process, create a pore water overpressure and to consolidate, despite a change in the external loading conditions.

  5. 3. Studies of the Effects of Industrial Processing on Fruit

    Author : Uno Viberg; Livsmedelsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Food and drink technology; antioxidants; invertase; thawing; blackcurrant; strawberry; fruit; berry; Livsmedelsteknik;

    Abstract : The industrial production of preserves includes several unit operations which all affects sensorial properties as well as the nutritional value of the final product. Thawing is a crucial unit operation, since then both chemical and physical changes take place. READ MORE

  7. 5. The Bentonite Barrier - Swelling Properties, Redox Chemistry and Mineral Evolution

    Author : Daniel Svensson; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; montmorillonite; bentonite; smectite; freezing; thawing; hydration; intercalation; four-water-layer; ethylene glycol; X-ray diffraction; time-resolved; spatial-resolution; XANES; Fe; redox; iron; ABM; TBT; Äspö;

    Abstract : Bentonite is planned for use as a buffer material in high-level radioactive waste repositories, where safety assessment is performed for very long periods (100-1000 ka). This thesis focuses on the swelling of smectites in liquid water, and analysis of bentonite from field experiments at Äspö Hard Rock Laboratory, Sweden. READ MORE
