  2. 1. Sodium Salt Scaling in Black Liquor Evaporators

    Author : Mathias Gourdon; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sodium carbonate; black liquor; falling film evaporation; fouling; scaling; heat transfer; sodium sulfate;

    Abstract : Sodium salt scaling has long been recognized as a problem in the recovery cycle of kraft pulp mills, especially in black liquor evaporators. In the black liquor evaporation, as the black liquor becomes more concentrated, the sodium salts, particularly sodium carbonate and sodium sulfate, will saturate and precipitate from the solution.

  4. 2. Model for activity coefficients and solubilities of Na2CO3 and Na2SO4 in high-temperature solutions

    Author : Marta Anna Bialik; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; scaling; Pitzer model; activity coefficient; solubility; sodium carbonate; sodium sulfate; boiling point raise; double salt; solid solution; burkeite;

    Abstract : Scaling of sodium sulfate and sodium carbonate double salts has long been recognized as a problem in the black liquor evaporation process. These salts are abundant in black liquor and often tend to precipitate on heat transfer areas, thereby significantly decreasing the heat transfer efficiency. READ MORE

  5. 3. Cellular regulation of heparan sulfate structure and function

    Author : Fariba Safaiyan; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biochemistry; Heparan sulfate; structure; biosynthesis; sulfation; Biokemi; Biochemistry; Biokemi; Medical and Physiological Chemistry; medicinsk och fysiologisk kemi;

    Abstract : Heparan sulfate (HS) is a sulfated glycosaminoglycan found on cell surfaces and in the extracellular matrix as HS proteoglycans. HS is synthesized as a polymer of alternating glucuronic acid and N-acetylglucosamine units. READ MORE

  6. 4. Galactosaminoglycans - Role in Brittlestar Limb Regeneration

    Author : Rashmi Ramachandra; Dorothe Spillmann; Barbara Mulloy; Uppsala universitet; []
    Keywords : Chondroitin sulfate; Dermatan sulfate; Brittlestar; Regeneration;

    Abstract : Regeneration is, in simple terms, ‘to re-grow’ damaged or lost parts of the body (e.g. cells, tissues and organs) and is a natural phenomenon occurring throughout the life of an organism. The regenerative capacity varies in the animal kingdom. READ MORE

  7. 5. Dynamic changes in T cell compartments and new approaches in evaluating DSS induced and Gai2 deficient colitis

    Author : Maria Fritsch Fredin; Göteborgs universitet; []
    Keywords : colitis; Gai2- - mice; dextran sodium sulfate; ex vivo cultures; micro-Computed Tomography; IEL; thymus; Inflammatory Bowel Disease;

    Abstract : The overall aim of this thesis was to increase the understanding of the immunopathology of Inflammatory Bowel Disease (IBD). The first aim was to elucidate how the thymus and the gut epithelium were affected by colitis. The second aim was to investigate new ways of assessing and monitoring colitis. READ MORE
