  1. 1. Extinctions and Ecosystem Stability

    Författare :Susanne Pettersson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; structural stability; ecosystems; interaction structure; Generalised Lotka-Volterra; complexity; local stability; dynamical systems; stability;

    Sammanfattning : Human society's expansion and demand for both biotic and abiotic natural resources exert a large pressure on ecosystems around the globe. Ecosystems are complex networks of species interacting with each other and their physical surroundings. LÄS MER

  3. 2. Studies of α-D-isosaccharinic Acid – Acid dissociation constant and structural conformations

    Författare :Stefan Ekberg; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; α-D-isosaccharinate; nuclear repository; α-D-isosaccharinic acid; potentiometric titration; equilibrium; acid dissociation constant; nuclear waste; stability constant; ion chromatography; α-D-isosaccharino-1; 4-lactone;

  4. 3. Mass Stabilization, Stability and Settlement in Mass Stabilized Peat

    Författare :Nenad Jelisic; Byggnadsmekanik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mass stabilization; stabilizer; field investigations; laboratory investigations; settlement; stability; peat; Building construction; Byggnadsteknik;

    Sammanfattning : Peat is badly suited as a base for road and railway embankments due to its geotechnical properties. The usual procedure has been, therefore, to excavate peat and replace it with blasted rock. LÄS MER

  5. 4. Black liquor gasification : experimental stability studies of smelt components and refractory lining

    Författare :Mathias Råberg; Dan Boström; Anders Nordin; Honghi Tran; Umeå universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; black liquor gasification; DTA; stability; thermal analysis; thermochemical data; HTM; HT-XRD; metastable; phase diagram; refractory lining; SEM; Chemical energy engineering; Kemisk energiteknik;

    Sammanfattning : Black liquors are presently combusted in recovery boilers where the inorganic cooking chemicals are recovered and the energy in the organic material is converted to steam and electricity. A new technology, developed by Chemrec AB, is black liquor gasification (BLG). LÄS MER

  7. 5. Stability and complexity of ecosystems - Global interaction constraints, landscape and extinctions

    Författare :Susanne Pettersson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Complexity; Collapse; Stability; Ecosystems; Extinctions; Population dynamics; spatial heterogeneity; Dynamical systems; dispersal;

    Sammanfattning : Human society's expansion and demand for both biotic and abiotic natural resources exert a large pressure on ecosystems around the globe. Ecosystems are complex networks of species interacting with each other and their physical surroundings. LÄS MER
