  1. 1. Seasonal variation and landscape regulation of dissolved organic carbon concentrations and character in Swedish boreal streams

    Författare :Anneli Ågren; Mats Jansson; Irena Creed; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; DOC; temporal variation; spatial variation; seasonal variation; forested catchment; wetland catchment; catchment characteristics; DOC characteristics; absorbance-ratio; bioavailability.; Physical geography; Naturgeografi;

    Sammanfattning : The seasonal variation and landscape regulation of dissolved organic carbon (DOC) concentrations in streams have been studied in two watersheds in the boreal zone. The seasonal variation was found to be highly correlated to variations in runoff. An increase in runoff was always accompanied with an increase in DOC concentration. LÄS MER

  3. 2. The MHC-glycopeptide-T cell interaction in collagen induced arthritis : a study using glycopeptides, isosteres and statistical molecular design in a mouse model for rheumatoid arthritis

    Författare :Lotta Holm; Jan Kihlberg; Morten Grötli; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Rheumatoid arthritis; collagen; T-cell; class II MHC; solid phase peptide synthesis; glycopeptide; peptide isostere; PCA; statistical molecular design; PLS; QSAR; sequence binding motif; Organic chemistry; Organisk kemi;

    Sammanfattning : Rheumatoid arthritis (RA) is an autoimmune disease affecting approximately 1% of the population in the western world. It is characterised by a tissue specific attack of cartilage in peripheral joints. Collagen induced arthritis (CIA) is one of the most commonly used animal models for (RA), with similar symptoms and histopathology. LÄS MER

  4. 3. Printability and Ink-Coating Interactions in Inkjet Printing

    Författare :Erik Svanholm; Göran Ström; Gunnar Engström; Janet Preston; Karlstads universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; coating; inkjet; print quality; printability; pigment; silica; polyvinyl alcohol; colorant; ink absorption; Chemical engineering; Kemiteknik; Chemical Engineering; Kemiteknik;

    Sammanfattning : Inkjet is a digital printing process where the ink is ejected directly onto a substrate from a jet device driven by an electronic signal. Most inkjet inks have a low viscosity and a low surface tension, which put high demands on the coating layer’s porosity and absorbency characteristics. LÄS MER

  5. 4. Acute Lymphoblastic Leukaemia in Adult Patients : Studies of Prognostic Factors, Treatment Results and in vitro Cellular Drug Resistance

    Författare :Helene Hallböök; Bengt Smedmyr; Elin Lindhagen; Lorentz Brinch; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicine; acute lymphoblastic leukaemia; adult; adolescent; chemotherapy; stem cell transplantation; in vitro assay; imatinib; Medicin; Dermatology and venerology; clinical genetics; internal medicine; Dermatologi och venerologi; klinisk genetik; invärtesmedicin;

    Sammanfattning : Treatment results and clinical characteristics in adult acute lymphoblastic leukaemia (ALL) were evaluated regarding three issues: a new treatment with cytarabine up-front, stem cell transplantation and a comparison between adult and paediatric treatment protocols. All studies were conducted on a national basis. LÄS MER

  7. 5. Application of indigenous materials in drinking water treatment

    Författare :Herbert Mpagi Kalibbala; Bengt Hultman; Joaquin Martinez; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Coagulant aid; drinking water treatment; dual media filtration; Moringa oleifera; primary coagulant; trihalomethanes; volcanic ash; Water in nature and society; Vatten i natur och samhälle;

    Sammanfattning : Volcanic ash and Moringa oleifera (M. oleifera) were investigated as indigenous materials for drinking water treatment based on problems identified at Kampala and Masaka water treatment plants in Uganda. LÄS MER
