  1. 21. Beyond Waste Management : Challenges to Sustainable Global Physical Resource Management

    Författare :Jagdeep Singh; Björn Frostell; Olga Kordas; Anju Singh; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Sustainable global physical resource management; global waste management; systems thinking; life cycle thinking; planning framework; global environmental justice; circular economy; Industrial Ecology; Industriell ekologi;

    Sammanfattning : Current physical resource management (PRM) was investigated in a global perspective in this thesis, to gain a deeper understanding of its implications in a sustainability perspective. In particular, the main challenges to the current PRM system and the kinds of systemic changes needed for sustainable PRM were examined. LÄS MER

  4. 23. Gas and dust in early galaxy evolution

    Författare :Jean Baptiste Jolly; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Galaxies: evolution -- Galaxies: high-redshift -- methods: stacking -- methods: data analysis -- techniques: interferometric;

    Sammanfattning : In order to study the content of distant galaxies without focusing solely on the brightest objects -- the tip of the iceberg -- I developed a tool:  LineStacker. As its name indicates this tool was designed to perform spectral stacking analyses. LÄS MER

  5. 24. Photospheric emission in gamma-ray bursts

    Författare :Christoffer Lundman; Felix Ryde; Stephan Rosswog; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : This thesis considers emission from gamma-ray bursts (GRBs), the most powerful explosions known in the Universe. Most GRBs are likely associated with the final stages of stellar evolution, where the core of a massive star collapses, and gives birth to a highly compact object such as a neutron star or black hole.

  7. 25. Energy Conversion and Particle Acceleration at Turbulent Plasma Jet Fronts

    Författare :Louis Richard; Yuri V. Khotyaintsev; Tomas Karlsson; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : High speed plasma flows (jets) are ubiquitous phenomena in the universe. For example, they carry energy from the most powerful sources (e.g active galactic nucleï AGN) to the medium at rest surrounding them. LÄS MER
