  1. 16. Sludge-derived char : utilisation as a metal sorbent in dilute wastewaters

    Författare :Ida Sylwan; Eva Thorin; Lena Johansson Westholm; Konrad Koch; Mälardalens universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sorption; adsorption; sludge; biosolids; metal; wastewater treatment; sorption; adsorption; slam; metaller; avloppsvattenrening; Energy- and Environmental Engineering; energi- och miljöteknik;

    Sammanfattning : Metal concentrations in soil and water have increased since the Industrial Revolution, which may have negative health and environmental effects. Metal pollution occurs, for instance, in municipal wastewater, industrial wastewater, and stormwater. Concentrations are often low, due to dilution. A common technology for metal removal is sorption.

  3. 17. Glucocorticosteroid therapy and steroid resistance in inflammatory bowel disease

    Författare :Lars Flood; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Ulcerative colitis; Crohn s disease; Steroid resistance; Glucocorticoid receptor; Nuclear Factor kappaB; Activator Protein 1; Adrenocorticotropin stimulation test; Metallothionein; Rofleponide;

    Sammanfattning : Ulcerative colitis (UC) and Crohn's disease (CD) are diseases of unknown aetiology often referred to as inflammatory bowel diseases (IBD). Glucocorticosteroids (GCS) have been used since the 1950's to treat acute attacks of these diseases. LÄS MER

  4. 18. Biophysical studies of membrane interacting peptides derived from viral and Prion proteins

    Författare :Kamila Oglęcka; Astrid Gräslund; Stephen White; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Prion peptides; Doppel peptide; Influenza fusion peptides; peptide-membrane interactions; translocation; linear dichroism; circular dichroism; Biophysics; Biofysik; Biophysics; biofysik;

    Sammanfattning : This thesis focuses on peptides derived from the Prion, Doppel and Influenza haemagglutinin proteins in the context of bilayer interactions with model membranes and live cells. The studies involve spectroscopic techniques like fluorescence, fluorescence correlation spectroscopy (FCS), circular and linear dichroism (CD and LD), confocal fluorescence microscopy and NMR.

  5. 19. Triggers of autoimmunity. Studies on gestational events

    Författare :Sabina Lindehammer; Celiaki och diabetes; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Islet autoantibodies; pregnancy; type 1 diabetes; celiac disease;

    Sammanfattning : Objective The primary aim of this thesis was to test whether gestational exposure to environmental factors may induce islet autoimmunity. The second aim was to determine to what extent the exposure to viruses or other environmental factors is a risk factor for type 1 diabetes in the offspring. LÄS MER

  7. 20. Deformation Behaviour, Microstructure and Texture Evolution of CP Ti Deformed at Elevated Temperatures

    Författare :Zhipeng Zeng; Stefan Jonsson; Hans J. Roven; Bevis Hutchinson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Commercially pure titanium; Zener–Hollomon parameter; Dynamic recovery; Dynamic recrystallization; Recrystallized volume fraction; Grain size; Flow stress; Constitutive equation; Texture; High angle grain boundary; Low angle grain boundary; Deformation twinning; Schmid factor; Misorientation; Hot compression; Slip system; Subgrain; EBSD; Construction materials; Konstruktionsmaterial;

    Sammanfattning : In the present work, deformation behavior, texture and microstructure evolution of commercially pure titanium (CP Ti) are investigated by electron backscattered diffraction (EBSD) after compression tests at elevated temperatures. By analysing work hardening rate vs. flow stress, the deformation behaviour can be divided into three groups, viz. LÄS MER
