  2. 1. Cross-scale perspectives on heterogeneity in Swedish boreal forests

    Author : Sofia Eriksson; Monica Hammer; Helle Skånes; Risto Kalliola; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; sustainable forest management; biodiversity conservation; landscape analysis; historical maps; ownership; Physical geography; Naturgeografi; geografi med naturgeografisk inriktning; Geography; Physical Geography;

    Abstract : Maintaining species diversity, ecosystem functioning, and socioeconomic values requires continued ecosystem heterogeneity across scales. This thesis aims to bridge gaps between ecological theory, environmental goals, and practical application of sustainable forest management needed to maintain such heterogeneity. READ MORE

  4. 2. Grading in physical education

    Author : Lena Svennberg; Karin Redelius; Jane Meckbach; Ann MacPhail; Gymnastik- och idrottshögskolan; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; physical education; assessment; movement qualities; criterion referenced; standards-based grading; internalised grading; gut-feeling; equity; Bernstein; Repertory Grid; Samhällsvetenskap Humaniora; Social Sciences Humanities;

    Abstract : In the thesis the aim is to investigate different aspects of what teachers value when grading in Swedish physical education (PE) and to analyses how sociological background factors impact students’ grades. Grades in PE have included aspects other than those prescribed in the grading criteria, for instance motivation and effort. READ MORE

  5. 3. Perceived Sensory Dimensions : A Human-Centred Approach to Environmental Planning and Design

    Author : Jonathan Stoltz; Ingrid Stjernquist; Peter Schlyter; Patrik Grahn; Christer Sandahl; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Green infrastructures; urban planning; environmental aesthetics; salutogenic design; multiple use; Physical Geography; naturgeografi;

    Abstract : Increased urbanization, stress and lifestyle related illness, and biodiversity loss are some of the most urgent challenges today. The potential contributions from green spaces and infrastructures in relation to these challenges are several. READ MORE

  6. 4. Surface structure and catalytic activity of Pd and Fe oxide surfaces and thin films

    Author : Mikhail Shipilin; Synkrotronljusfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Surface X-ray diffraction SXRD ; Heterogeneous catalysis; Pd; PdO; Fe; FeO; Thin films; Fysicumarkivet A:2016:Shipilin;

    Abstract : The present work is devoted to atomic scale structural studies of the surfaces of model heterogeneous catalysts relevant to oxidation reactions. A novel approach using high-energy surface X-ray diffraction combined with mass-spectrometry measurements is employed to perform in situ structural characterization of Pd(100) and Pd(553) single crystal surfaces acting as catalysts in the process of CO oxidation under semirealistic conditions.

  7. 5. Source Term Model Approaches to Film Cooling Simulations

    Author : Petter Dahlander; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Film cooling simulations using Computational Fluid Dynamics (CFD) are very difficult and extremely computer power demanding. This thesis deals with the development of a method to save computer power for these types of simulations. The cooling air is injected using additions to the source terms of the discretised governing equations. READ MORE
