  2. 1. Stochastic analysis of fluid flow and tracer pathways in crystalline fracture networks

    Author : Andrew Frampton; Vladimir Cvetkovic; Allen Shapiro; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Groundwater; Fractured media; Transport; Retention; Macrodispersion; Lagrangian formulation; Stochastic modelling; Earth sciences; Geovetenskap; Hydrology; Hydrologi; Environmental engineering; Miljöteknik;

    Abstract : Understanding groundwater flow systems and how these control transport is an essential part in assessing the suitability of subsurface environments as hosts for storage of toxic waste. Therefore it is important to be able to integrate knowledge obtained from field characterisation of the subsurface with methods which can be used to evaluate and predict possible impact on surrounding environments.

  4. 2. Improvements of U-pipe Borehole Heat Exchangers

    Author : José Acuña; Björn Palm; Signhild Gehlin; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Borehole Heat Exchanger; Distributed Thermal Response Test; Ground Source Heat Pumps; Environmental engineering; Miljöteknik; Earth sciences; Geovetenskap; Civil engineering and architecture; Samhällsbyggnadsteknik och arkitektur;

    Abstract : The sales of Ground Source Heat Pumps in Sweden and many other countries are having a rapid growth in the last decade. Today, there are approximately 360 000 systems installed in Sweden, with a growing rate of about 30 000 installations per year. READ MORE

  5. 3. An integrated study of geological, magnetic and electromagnetic data for mineral exploration in the Jameson Land Basin, central East Greenland

    Author : Anaïs Brethes; Thorkild Maack Rasmussen; Florian Wellmann; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; central East Greenland; Jameson Land Basin; base metal mineralization; geological structures; magnetic data; electromagnetic data; Prospekteringsgeofysik; Exploration Geophysics;

    Abstract : The Jameson Land Basin, located in central East Greenland, initiated in Devonian time with the collapse of the over-thickened Caledonian Orogen. The basin developed during different phases of rifting from the late Paleozoic to the Mesozoic and has accumulated between 16-18 km of sediments. READ MORE

  6. 4. Geometallurgy of a complex ore : Lappberget Zn-Pb-Ag-(Cu-Au) deposit, Garpenberg mine, Sweden

    Author : Glacialle Tiu; Christina Wanhainen; Yousef Ghorbani; Nils Jansson; Jens Gutzmer; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ore Geology; Malmgeologi;

    Abstract : Complex ores, in this instance, a polymetallic base metal ore with additional precious and penalty elements, pose particularly tough challenges for successful production forecasts. Plant performance and recoveries for complex ores are more difficult to predict due to the larger number of variables that must be considered, tracked, and characterized during the multi-stage separation process.

  7. 5. Operationalizing Industrial Ecology in the Waste Sector : Roles and tactics for circular value innovation

    Author : Graham Aid; Nils Brandt; Monika Olsson; Maria Malmström; Leenard Baas; Stefan Anderberg; Mats Eklund; Anna Björklund; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Abstract : The take-make-waste approach to resource management in human production and consumption systems is contributing to a variety of environmental and social problems worldwide. Additionally, as the world’s population and affluence increase, so do the negative impacts of poor resource management. READ MORE
