1. 26. The genomic signatures of adaptive evolution in Populus

   Författare :Jing Wang; Pär Ingvarsson; Barbara Mable; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Populus; adaptive evolution; natural selection; genomic diversity and divergence; recombination; Next-generation sequencing; local adaptation;

   Sammanfattning : Understanding the genetic basis of adaptive evolution, and how natural selection has shaped patterns of polymorphism and divergence within and between species are enduring goals of evolutionary genetics. In this thesis, I used whole genome re-sequencing data to characterize the genomic signatures of natural selection along different evolutionary timescales in three Populus species: Populus tremula, P.

3. 27. Engaged in digital service innovation

   Författare :Lars-Olof Johansson; Ulrika Lundh Snis; Dick Stenmark; Harald Holone; Högskolan Väst; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Digital service innovation; Human-Centred Service Systems; value; practice perspective; learning in practice; engaged scholarship research; Work Integrated Learning; Arbetsintegrerat lärande; Informatik; Informatics;

   Sammanfattning : The research in this thesis has digital services innovation to support Human-Centred Service Systems (HCSSs) from a practice theory perspective as a foundation. Digital service innovation is understood as service system reconfiguration due to digitalization, with the aim to change the service systemsin a way that increases the value for the involved actors.

4. 28. REACTIVE TRANSPORT MODELLING OF DISSOLVED CO2 IN POROUS MEDIA : Injection into and leakage from geological reservoirs

   Författare :Nawaz Ahmad; Anders Wörman; Auli Niemi; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CO2 geological storage and safety; leakage of brine saturated with dissolved CO2; reactive transport; fracture; advection; dispersion and diffusion; sorption; carbonate minerals kinetic reactions; calcite; dolomite; siderite; porosity; permeability; heat transport; Land and Water Resources Engineering; Mark- och vattenteknik;

   Sammanfattning : The geological sequestration of carbon dioxide (CO2) is one of the options of controlling the greenhouse gas emissions. However, leakage of CO2 from the storage reservoir is a risk associated with geological sequestration. Over longer times, large-scale groundwater motion may cause leakage of dissolved CO2 (CO2aq).

5. 29. A Verification Framework for Component Based Modeling and Simulation : “Putting the pieces together”

   Författare :Imran Mahmood; Rassul Ayani; Gary Tan; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Modeling and Simulation; Component-based development; Composability; Semantic Composability; Dynamic-Semantic Composability; Verification; Correctness; Petri Nets Analysis; Algebraic Techniques; Colored Petri Nets; State-space Analysis; Communicating Sequential Processes; Model Checking.; SRA - ICT; SRA - Informations- och kommunikationsteknik;

   Sammanfattning : The discipline of component-based modeling and simulation offers promising gains including reduction in development cost, time, and system complexity. This paradigm is very profitable as it promotes the use and reuse of modular components and is auspicious for effective development of complex simulations. LÄS MER

7. 30. Modelling phosphorus dynamics in constructed wetlands upgraded with reactive filter media

   Författare :Rajabu Hamisi; Gunno Renman; Berit Balfors; Roger Thunvik; Steve W. Lyon; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Constructed Wetland; COMSOL; Modelling; Reactive Solute Transport; Sorption Process; Mark- och vattenteknik; Land and Water Resources Engineering;

   Sammanfattning : Developing low-cost and effective technologies to upgrade phosphorus (P) removal from the catchment runoffs and rural wastewater treatment facilities is one of the main research agendas to save the Baltic Sea from eutrophication. In Sweden, the construction of the constructed wetlands has been one of the environmental objectives for wastewater quality improvement in the small communities. LÄS MER
