  1. 21. Land-use competition and agricultural greenhouse gas emissions in a climate change mitigation perspective

    Författare :David Bryngelsson; Chalmers tekniska högskola; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Bioenergy; Diets; Livestock; Integrated assessment model; Land use competition; GHG emissions; Partial equilibrium model; Mitigation; Food consumption; Climate change;

    Sammanfattning : Productive land for food production, bioenergy, or preservation of nature is a limited resource. Climate change mitigation puts additional pressure on land via higher demand for bioenergy to replace fossil fuels and via restrictions on deforestation—two processes that limit the availability of land for food produc- tion, and may thus also raise food prices.

  3. 22. Crossing the threshold : Visualization design and conceptual understanding of evolution

    Författare :Andreas C. Göransson; Lena Tibell; Konrad Schönborn; Anat Yarden; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Evolution; Natural selection; Visualization; Conceptual understanding; Conceptual change;

    Sammanfattning : The theory of evolution is considered the unifying theory of biology. An accurate understanding of evolution is vital both for the understanding of diverse topics in biology, but also for societal issues such as antibiotic resistance or biodiversity. LÄS MER

  4. 23. Conceptual Design of Propulsion Systems for Boundary Layer Ingestion

    Författare :Sebastian Samuelsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; turbo-electric aircraft; performance modeling; Aviation; boundary layer ingestion; aircraft engine; conceptual design; propulsion integration;

    Sammanfattning : To reduce the climate impact of aviation new aircraft and engine concepts as well as improved design methods are needed. In this thesis, two fronts are explored. The first concerns improved methods for the conceptual design of the engine. LÄS MER

  5. 24. Views of Research Quality in Empirical Software Engineering

    Författare :Jefferson Seide Molléri; Kai Petersen; Emilia Mendes; Yvonne Dittrich; Blekinge Tekniska Högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Research Quality; Quality Standards; Empirical Software Engineering; Research Methodology;

    Sammanfattning : Background. Software Engineering (SE) research, like other applied disciplines, intends to provide trustful evidence to practice. To ensure trustful evidence, a rigorous research process based on sound research methodologies is required. LÄS MER

  7. 25. Facets of chemical bonding that enhance or encumber conceptual understanding

    Författare :Anders Nimmermark; Chalmers tekniska högskola; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; student surveys; chemical bonding; secondary school; tertiary education; coordination chemistry; conceptual understanding;

    Sammanfattning : Chemical bonding is a vast subject, rich in abstract concepts and advanced and less-advanced explanatory models that the learner has to master. In this context, the teaching of chemical bonding at the secondary school level is extremely important, as it has the potential to increase or hinder students’ further understanding of bonding.
