  2. 1. Effects of the Higgs field on Inflation and Reheating

    Author : Aliki Litsa; Katherine Freese; Jens Jasche; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; inflation; reheating; Higgs; non-gaussianity; cosmological perturbations; Theoretical Physics; teoretisk fysik;

    Abstract : The model of inflation - a period of accelerated expansion in the very early Universe - was introduced to give solutions to a number of problems encountered in the Standard Big Bang paradigm. Additionally, due to its quantum nature, inflation is able to generate the necessary primordial inhomogeneity “seeds”, which eventually evolve into large-scale structures. READ MORE

  4. 2. Semi-Solid Casting of Aluminium and Magnesium Alloys: Slurry Production and Rheocasting using the Rapid Slurry Forming Technology

    Author : Olof Granath; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Slurry; RheoMetal; Process parameter; Aluminium alloys; Semi-solid; Rheocasting; Rapid Slurry Forming; Magnesium alloys; Reheating;

    Abstract : Semi-solid casting was developed in the early 1970’s and involves the use of a partially solidified metal slurry. This method of casting has become a popular alternative for production of automobile components. READ MORE

  6. 4. Producer Gas Implementation in Steel Reheating Furnaces from Lab to Industrial Scale : A Computational Fluid Dynamics and Thermodynamics Approach

    Author : Mohsen Saffari Pour; Pär Göran Jönsson; Henrik Saxen; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknisk materialvetenskap; Materials Science and Engineering;

    Abstract : The integrated steel-making plants in Sweden contributed with approximately 8 % of the total CO2 emissions in the country in 2011. A major contributor to these emissions is the combustion of fossil fuels in different process units. Therefore, it is essential to reduce emissions by limiting the fossil fuels consumption in the steel industry. READ MORE

  7. 5. Magnetic Resonance Imaging of Human Brown Adipose Tissue : Methodological Development and Application

    Author : Elin Lundström; Joel Kullberg; Håkan Ahlström; Lars Johansson; Robin Strand; Sven Månsson; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Brown adipose tissue; Magnetic resonance imaging; Positron emission tomography; Image segmentation; Glucose metabolism;

    Abstract : Brown adipose tissue (BAT) is a thermogenic organ with the main human depot located in the cervical-supraclavicular (sBAT) region. BAT is proposed as a potential therapeutic target for obesity and diabetes. READ MORE
