  4. 2. Solar Assisted Pervaporation : A process for the concentration of fruit juices in membrane pouches with solar energy

    Author : Randi Phinney; Avdelningen för livsmedel och läkemedel; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; pervaporation; solar drying; membrane pouch; juice concentration; fruit preservation; marmalade; tangerine; Vangueria infausta; microbiology; water activity; soluble solids; Brix;

    Abstract : Drying has been used for thousands of years to preserve foods. One of the first methods used was open air sun drying which exposes foods directly to solar radiation and ambient air. This method is still used today around the world but it remains underdeveloped on a small-scale for two main reasons. READ MORE

  6. 4. Colonic pouch anastomosis after rectal excision for cancer

    Author : Olof Hallböök; Neil J. M. Mortensen; Linköpings universitet; []
    Keywords : Total mesorectal excision; low anterior resection; colonic pouch; coloanal anastomosis; neorectum; quality of life; laser-Doppler flowmetry; gut peptides; anorectal physiology; MEDICINE; MEDICIN;

    Abstract : Anastomoses at the level of the pelvic floor will become increasingly more common in rectal cancer surgery when total mesorectal excision is used as a standard procedure to obtain local mdicality. A consequence of such low anastomoses is increased risk of healing disturbances and poor distal bowel function, The aim of this thesis was to focus on reconstruction after total mesorectal excision.

  7. 5. Egg size evolution and paternal care in pipefishes

    Author : Inês Braga Gonçalves; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Egg size; embryo development; embryo survival; hypoxia; male quality; mate choice; mating constraints; oxygen; parental care; parental effects; paternal care; reproductive compensation; sex-role reversal; sexual conflict; Syngnathidae; Syngnathus typhle;

    Abstract : In this thesis I explore how sexual selection, sexual conflicts, coevolution with parental care and an environmental selective agent (hypoxia) affect the evolution of different egg characteristics and embryo survival and size in pipefishes (Syngnathidae). In the broad-nosed pipefish, Syngnathus typhle Linnaeus, both sexes prefer to mate with large partners; large females produce more and larger eggs and large males can care for more young, and, as shown in this thesis, invest more per embryo and provide better oxygenation during brooding.
