  2. 21. Fat contamination of pericardial suction blood in cardiac surgery : clinical and experimental studies in perspectives of transfusion logistics

    Author : Micael Appelblad; Gunnar Engström; Krister Lindmark; Anders Jeppsson; Umeå universitet; []
    Keywords : Surgery; blood transfusion; cardiopulmonary bypass; pericardial suction blood; fat contamination; lipid microemboli; density separation; surface adsorption; Kirurgi; Surgery; kirurgi;

    Abstract : Introduction: During cardiac surgery aided by cardiopulmonary bypass (CPB) the autotransfusion of pericardial suction blood (PSB) is regarded mandatory to limit allogeneic blood exposure. PSB is however proposed as a source of lipid microemboli and to contribute to brain damage. READ MORE

  4. 22. Investigations of passive safety systems in LWRs : melt coolability with bottom coolant injection, light gas effects on a passive containment cooling system

    Author : Domenico Paladdino; KTH; []
    Keywords : ;

    Abstract : The key objectives in introducing passive features in thesafety systems for Light Water Reactor (LWR) are to increasetheir reliability, to simplify the design of the plants and toimprove performance and economics. Component and integralsystem tests in scaled facilities are required for optimizingthe design and for certification of these safety systems. READ MORE

  5. 23. The role of liver myeloid cells in obesity and metabolic disease

    Author : Emelie Barreby; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Macrophages are tissue resident cells with diverse phenotypes and functions depending on their origin, localization and physiological context. In the liver, their main functions are to detoxify the blood from pathogens, debris and metabolic waste arriving to the liver through the systemic and portal circulation. READ MORE

  6. 24. Glacial dynamics and till genesis in hilly terrain : A study in the Tallträsk area, central-northern Sweden

    Author : Hans Ivarsson; Mats Jansson; Per Möller; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; till analyses; glacial stratigraphy; subglacial deposition; deglaciation; hilly terrain; northern Sweden; Physical geography; Naturgeografi;

    Abstract : This study deals with the influence of topography on glacial dynamics and the genesis of till in an area of moder-ate bedrock relief. An area 25 km west of Lycksele, northern Sweden, was investigated using geomorphological and sedimentological methods. READ MORE

  7. 25. Holocene and Latest Glacial Paleoceanography in the North-Eastern Skagerrak

    Author : Richard Gyllencreutz; Jan Backman; Eve Arnold; Reidulv Bøe; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Skagerrak; Holocene; sediment; chirp sonar; grain size; mineral magnetic properties; Earth sciences; Geovetenskap;

    Abstract : Detailed information on past oceanographic and climatic changes is crucial for our understanding of natural climate variability and for the assessment of future climate variations. Sediments strongly influenced by the North Atlantic Current accumulate at high rates in the northeastern Skagerrak, forming a potential highresolution archive for information on past climatic and oceanographic processes and events.
