  1. 1. Chemical Stabilization of Arsenic in Contaminated Soil under Low Redox Conditions

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Eva Smedborn Pausson; [2019]
    Keywords : ;

    Abstract : Remediation techniques for arsenic contaminated soil have previously focused mostly on the surface soil layers where aerobic conditions are prevalent. In this master thesis, chemical stabilization by adding zero-valent iron (Fe(0)) and calcium oxide (CaO) to an arsenic-contaminated soil under low redox conditions have been studied through up-flow percolation tests.

    Abstract : The interest in modeling non-maturing deposits has skyrocketed ever since thefinancial crisis 2008. Not only from a regulatory and legislative perspective,but also from an investment and funding perspective.Modeling of non-maturing deposits is a very broad subject. READ MORE

  3. 3. Importance of fish community structure, nutrients and browning for shallow lake ecosystem dynamics : A modelling perspective

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Ylva Karlberg; [2019]
    Keywords : biological modelling; bowning; food webs; trophic interactions; top-down and bottom-up control; nutrients; light; shallow lake; biologisk modellering; brunifiering; födovävar; trofiska interaktioner; näring; ljus; grund sjö;

    Abstract : In a changing climate, it is increasingly important to be able to model environmental effects on food webs, and to do that, one must have appropriate dynamic models. I present a shallow lake ecosystem model where producers, grazers, carnivores, piscivores, and detritivores are coupled through resource (light, nutrients and detritus) fluxes between the benthic and pelagic habitats and through carnivore life history events (ontogenetic habitat and diet shifts).

  4. 4. Numerical Investigation of Various Modelling Strategies for Throttling a Transonic Compressor Rig Diffuser

    University essay from KTH/Kraft- och värmeteknologi

    Author : Borzou Dargahi; [2019]
    Keywords : ;

    Abstract : The concern of this study is modeling of the flow field in the diffuser of a 1.5 stage compressor test rig in which the mass flow is constrained at the exit of the diffuser. Constraining method is is applied through, throttling by means of a slab at the exit of the diffuser, where the flow enters the exit volute. READ MORE

  5. 5. Med kroppen som måttstock : en undersökning om virtuella upplevelser av landskapsarkitektur, baserade på BIM-modeller, är effektiva arbets- och kommunikationsredskap

    University essay from SLU/Department of Landscape Architecture, Planning and Management (from 130101)

    Author : Werner Nystrand; [2019]
    Keywords : landskapsarkitektur; virtuell verklighet; visualisering; dialogverktyg; digital modellering; BIM; Building Information Modell; datorspel;

    Abstract : Detta examensarbete har undersökt användningen av ”tekniker för virtual reality” (hädanefter: virtuella upplevelser, se s. 13) vid kommunikation av landskapsarkitektur, både i teori och praktisk utvärdering. READ MORE
