  2. 1. Maternal and neonatal metabolomes and their associations to immune maturation and allergy in early life

    Author : Olle Hartvigsson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Untargeted Metabolomics; allergy; QC; quality control; plasma; umbilical cord; placenta; LC-MS; immune system;

    Abstract : Allergy, one of the most common chronic diseases worldwide, is caused by a dysregulated immune system reacting to normally harmless proteins. However, regulating mechanisms are not well understood. The aim of this thesis was to investigate if plasma and placenta metabolites associate prospectively to allergy development and immune maturation. READ MORE

  4. 2. Structural behaviour of shotcrete in hard rock tunnels

    Author : Andreas Sjölander; Anders Ansell; Richard Malm; Fredrik Johansson; Eivind Grøv; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; shotcrete; structural behaviour; material models; rock support; bond strength; fibre-reinforcement; Concrete Structures; Betongbyggnad;

    Abstract : Tunnels in hard and jointed rock are normally excavated in an arch shape to enable the rock mass to support its weight. Since the beginning of the 1980's, fibre reinforced shotcrete (FRS) in combination with rock bolts have been the dominating support method for hard rock tunnels. READ MORE

  5. 3. The role of biobased building materials in the climate impacts of construction : Effects of increased use of biobased materials in the Swedish building sector

    Author : Diego Peñaloza; Magnus Wålinder; Martin Erlandsson; Andreas Falk; Johanna Berlin; Dimitris Athanassiadis; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LCA; timber buildings; timber bridges; biobased building materials; dynamic LCA; climate change mitigation; building stock; scenario analysis; biogenic carbon; Byggvetenskap; Civil and Architectural Engineering;

    Abstract : A significant share of the global climate change impacts can be attributed to the construction sector. One mitigation strategy is increasing the use of biobased materials. Life cycle assessment (LCA) has been used to demonstrate the benefits of this, but forest complexities create uncertainty due to omission of key aspects. READ MORE

    Abstract : Forest biomass is expected to play an increasingly important role in tomorrow´s global bio-economy as one of the main renewable sources of materials, chemicals and energy. In the framework of the biorefinery concept, the forestry industry is looking for new processes to utilize several fractions in the biomass (cellulose, hemicelluloses, lignin etc. READ MORE

  7. 5. Evaluation of Innovative Rehabilitation Technologies Utilising Polymer Composites for Aging Sewer Systems

    Author : Parastou Kharazmi; Folke Björk; Tord af Klintberg; Tor Broström; KTH; []
