  1. 1. Fouling of Ultrafiltration Membranes due to Adsorption of a fatty acid

    Författare :Jeanette Lindau; Avdelningen för kemiteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ultrafiltration Fouling Adsorption Characterisation ESCA FTIR SEM-EDX Ellipsometry Cleaning Capillary condensation; Chemical technology and engineering; Kemiteknik och kemisk teknologi;

    Sammanfattning : A study of fouling of ultrafiltration membranes due to adsorption of a fatty acid in the membrane matrix has been done. Octanoic acid was used as a model substance. LÄS MER

  3. 2. Clinical differentiation between frontotemporal dementia and Alzheimer's disease : psychometric, behavioral, neuroimaging and neurophysiological information

    Författare :Maria Lindau; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Frontotemporal dementia (FTD) initially affects the anterior regions of the brain, and gradually spreads to other cerebral areas. Behavioral alterations are described as the hallmark of FTD, whereas cognition is mostly found to be relatively spared. LÄS MER

  4. 3. Immune regulation at the foetal-maternal interface; implications for healthy and complicated pregnancies

    Författare :Robert Lindau; Jan Ernerudh; Maria Jenmalm; Kristina Nilsson-Ekdahl; Petra Arck; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : For a successful pregnancy, the maternal immune system must acquire tolerance towards the paternal antigens present in the semi-allogeneic foetus. This tolerance is mainly established locally at the foetal-maternal interface, where foetally-derived trophoblasts invade the maternal endometrium (called decidua during pregnancy) and come in close proximity to maternal immune cells.

  5. 4. The Impact of High-Quality Information on Performance in Manufacturing

    Författare :Roger Lindau; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; real-time; automatic data capture; planning; disturbances; high-quality information; manufacturing; disturbance absorption measures; scheduling;

    Sammanfattning : The dissertation deals with the impact of high-quality information on performance in manufacturing. In a system where two material flows with sequence dependency are matched, the use of real-time information to monitor and control the sequencing buffer improves the system's ability to schedule many different models, compared with a system with no information at all.

  7. 5. Pulp washing - Determining local properties using a new measurement technique

    Författare :Jenny Lindau; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; local properties; displacement washing; washing; measurement technique; pulp washing;

    Sammanfattning : There are many incentives for making the pulp washing process as efficient as possible: an efficient separation of the pulp from the black liquor will save a substantial amount of energy, reduce costs by reducing the need for make-up chemicals and improve the bleaching process. There are many discrepancies in the literature, however, as to how different parameters influence washing efficiency. LÄS MER
