  2. 1. Palsa Growth and Decay in Northern Sweden : Climatic and Environmental Controls

    Author : Frieda S. Zuidhoff; Jonas Åkerman; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; Earth sciences; ground thermal properties; palsas; permafrost degradation; peat porosity; Sweden; vegetation.; Geovetenskap; Earth sciences; Geovetenskap; naturgeografi; Physical Geography;

    Abstract : This thesis outlines the development and decay of palsas in northern Sweden in relation to climatic and environmental factors. Palsas were investigated on morphology, vegetation, peat porosity, ground temperature and local climate in four bogs situated on a north-south gradient in northern Sweden. READ MORE

  4. 2. Identification, validation and clinical application of a three-gene signature for accurate prognosis prediction and treatment selection of newly diagnosed prostate cancer

    Author : Zhuochun Peng; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : This thesis presents a complete, comprehensive and stepwise approach of translational molecular research. Starting from whole-genome bioinformatics analyses based on the embryonic stem (ES) cell hypothesis, a three-gene signature was identified, validated with the goal of clinical application in order to optimize treatment decision based on improvement of overall survival estimation.

  5. 3. Gyrokinetic simulations of microturbulence and transport in tokamak plasmas

    Author : Daniel Tegnered; Chalmers University of Technology; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; ITG; Joint European Torus; impurities; transport; fusion; TEM; tokamak; turbulence; plasma physics; gyrokinetics;

    Abstract : Fusion power is one of few viable and sustainable means of energy production. The tokamak is arguable the most mature technology to magnetically confine fusion plasmas. In these devices, heat and particle transport is dominated by small-scale turbulent fluctuations. READ MORE

  6. 4. The clinical value of genetic analyses of bone and soft tissue tumors

    Author : Charles Walther; Avdelningen för klinisk genetik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : Tumors of bone and soft tissue are common but only constitute 1 % of all malignant tumors. The malignant tumors are often difficult to diagnose due to their rarity and morphological resemblance between subtypes. This makes the diagnostic process challenging. READ MORE

  7. 5. Development of RMT techniques for urban infrastructure planning : Stockholm Bypass (Förbifart) case study

    Author : Suman Mehta; Alireza Malehmir; Mehrdad Bastani; Laust Pedersen; Andreas Pfaffhuber; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Geofysik med inriktning mot fasta jordens fysik; Geophysics with specialization in Solid Earth Physics;

    Abstract : The tensor radio-magnetotelluric (RMT) method has extensively been used in near-surface investigations to obtain resistivity models of the subsurface. The main objective of this thesis is to further develop the RMT survey technique for a less paid attention and challenging environment namely on shallow water bodies and in the urban environment.
