1. 1. Live and Let Die : Critical regulation of survival in normal and malignant hematopoietic stem and progenitor cells

   Författare :Pernilla Eliasson; Jan-Ingvar Jönsson; Mikael Sigvardsson; Urban Gullberg; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; hematopoietic stem cells; hypoxia; self-renewal; survival; acute myeloid leukemia; FLT3; Cell and molecular biology; Cell- och molekylärbiologi; Haematology; Hematologi;

   Sammanfattning : The hematopoietic stem cell (HSC) is characterized by its ability to self-renew and produce all mature blood cells throughout the life of an organism. This is tightly regulated to maintain a balance between survival, proliferation, and differentiation. LÄS MER

   Sammanfattning : Cellulosabaserade material är världens rikligast förekommande förnyelsebara råvara. Växters cellväggar är naturliga kompositmaterial där den kristallina cellulosan är inbäddad i en väv av hemicellulosa, strukturproteiner och lignin. LÄS MER

4. 3. C-reactive protein (CRP) and anti-CRP autoantibodies in systemic lupus erythematosus : a study on the occurrence and clinical implications of anti-CRP antibodies and CRP-mediated complement activation

   Författare :Christopher Sjöwall; Thomas Skogh; Johan Frostegård; Linköpings universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; autoantibodies; complement activation; C-reactive protein; cytokines; immune complex; immunoregulation; opsonization; systemic lupus erythematosus; Rheumatology; Reumatologi;

   Sammanfattning : Systemic lupus erythematosus (SLE) is an autoimmune disease characterized by production of a wide range of autoantibodies, multiple organ involvement and by local formation or tissue deposition of immune complexes (ICs) in the inflamed organs. In contrast to most systemic inflammatory conditions, and despite raised levels of pro-inflammatory cytokines, SLE flares are rarely reflected by elevated C-reactive protein (CRP), an important acute-phase reactant in man with homologs in vertebrates and several invertebrates.

5. 4. Closing the Loop by Combining UASB Reactor and Reactive Bed Filetr Technology for wastewater Treatment : Modelling and Practical Approaches

   Författare :Raúl Rodríguez-Gómez; Gunno Renman; Björn Vinnerås; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bench-scale experiment; Modelling; Polonite; Sorbulite; UASB; Wastewater; Mark- och vattenteknik; Land and Water Resources Engineering;

   Sammanfattning : A laboratory-scale upflow anaerobic sludge blanket (UASB) reactor followed by a packed bed reactor (PBR) filled with Sorbulite® in the lower part and Polonite® in the upper part was used to treat household wastewater in a 50-week experiment. A model was developed to describe the performance of the UASB reactor, including mass transfer through the film around anaerobic granules, intra-particle diffusion and bioconversion of the substrate.

7. 5. Atomic Scale Design of Clean Energy Materials : Efficient Solar Energy Conversion and Gas Sensing

   Författare :Jawad Nisar; Rajeev Ahuja; Puru Jena; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Photocatalysts; Band gap narrowing; Water dissociation; Density functional theory; Gas sensing; Kaolinite; Physics with spec. in Atomic; Molecular and Condensed Matter Physics; Fysik med inriktning mot atom- molekyl- och kondenserande materiens fysik;

   Sammanfattning : The focus of this doctoral thesis is the atomic level design of photocatalysts and gas sensing materials. The band gap narrowing in the metal oxides for the visible-light driven photocatalyst as well as the interaction of water and gas molecules on the reactive surfaces of metal oxides and the electronic structure of kaolinite has been studied by the state-of-art calculations.
