  3. 12. Novel approaches in modeling of soil carbon : Upscaling theories and energetics

    Författare :Arjun Chakrawal; Stefano Manzoni; Hyun-Seob Song; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Microorganisms; soil C cycling; spatial heterogeneity; energetics; thermodynamics; microbial metabolism; calorespirometric ratio; microbial traits; heat dissipation; microscale; Physical Geography; naturgeografi;

    Sammanfattning : Soils contain more carbon (C) than terrestrial (above ground) and atmospheric carbon combined. Mismanagement of soil C could lead to increased greenhouse gas emissions, whereas practices leading to increased C storage would help mitigate climate change while improving soil fertility and ecological functions.

    Sammanfattning : Tradition and change in compulsory school teacher education are studied historically, using the theoretical framework of curriculum theory and theory of cultural reproduction. The concepts of classification and framing are used as analytic devices. LÄS MER

  5. 14. Optimization and Execution of Complex Scientific Queries

    Författare :Ruslan Fomkin; Tore Risch; Marianne Winslett; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; scientific databases; query processing; data streams; cost-based query optimization; query rewritings; databases and Grids; Computer science; Datavetenskap; Data- och systemvetenskap; Computer Systems Sciences;

    Sammanfattning : Large volumes of data produced and shared within scientific communities are analyzed by many researchers to investigate different scientific theories. Currently the analyses are implemented in traditional programming languages such as C++. LÄS MER

  7. 15. Superconformal Theories in Six Dimensions

    Författare :Pär Arvidsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; String theory; Field theories in higher dimensions; Superconformal symmetry;

    Sammanfattning : This thesis consists of an introductory text, which is divided into two parts, and six appended research papers.The first part contains a general discussion on conformal and superconformal symmetry in six dimensions, and treats how the corresponding transformations act on space-time and superspace fields.
