  1. 6. Heavy metals in municipal solid waste deposits

    Författare :Peter Flyhammar; Institutioner vid LTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; teknisk geologi; Hydrogeologi; geographical and geological engineering; Hydrogeology; substrate; transformation; emission; environment; MSW; heavy metals; accumulation; teknisk geografi; Geophysics; physical oceanography; meteorology; Geofysik; fysisk oceanografi; meteorologi; Environmental technology; pollution control; Miljöteknik; kontroll av utsläpp;

    Sammanfattning : Extensive use of heavy metals in modern society influences routes followed by fluxes on the surface of the Earth. The changed flow paths may be harmful for the balance of biological systems at different levels, micro-organisms, human beings and whole ecosystems, since the toxicity of heavy metals is determined by their concentrations and chemical forms.

  3. 7. Global-Scale Modelling of the Land-Surface Water Balance : Development and Analysis of WASMOD-M

    Författare :Elin Widén-Nilsson; Sven Halldin; Chong-yu Xu; Lars-Christer Lundin; Jens Christian Refsgaard; Uppsala universitet; []
    Nyckelord :Hydrology; Global; Water balance; Runoff; Regionalisation; Model uncertainty; Multi-objective; Parameter; Evaluation criteria; Routing; Climate change; Hydrologi;

    Sammanfattning : Water is essential for all life on earth. Global population increase and climate change are projected to increase the water stress, which already today is very high in many areas of the world. The differences between the largest and smallest global runoff estimates exceed the highest continental runoff estimates. LÄS MER

  4. 8. Relaxation dynamics of perturbed water and other H-bonded liquids

    Författare :Johan Sjöström; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; confinement; supercooled water; dielectric relaxation; mixtures;

    Sammanfattning : Most liquids can be supercooled below its melting point where the dynamics dramatically slows down with decreasing temperature until the material appears solid on the experimental time scale and becomes stuck in an out-of-equilibrium configuration, a glass. Water, one of the most abundant substances on earth, is no exception. LÄS MER

  5. 9. Atomistic simulations of structural and dynamical properties of liquids under geometric constraints

    Författare :Lorenzo Agosta; Alexander Lyubartsev; Marialore Sulpizi; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; liquid; contraint; TiO2; surfaces; bio-inorganic; molecular dynamic; ab-initio; tight-binding; DFT; metadynamic; free energy; nanoparticles; water; amino acids; adsorption; mesophases; hexatic; smectic; triply periodic network; Fddd; fysikalisk kemi; Physical Chemistry;

    Sammanfattning : The statistical-mechanical description of liquids represents a formidable problem in physic due to the absence of the analytical theory of the liquid state. Atomistic simulations represent a unique source of information in this respect and can be implemented in order address macroscopically measurable liquid properties, including its structure and dynamics, based on the information of the interactions between its constituent molecules.

  7. 10. Secondary currents in groundwater

    Författare :Maria Engström; Bo Nordell; Anders Sellgren; Clifford Voss; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Groundwater; Vattenteknik; Water Resources Engineering;

    Sammanfattning : The thesis concerns the small vertical water movements created by thermal convection and the Coriolis force acting on groundwater flows. These small flows are of importance to vertical transports of temperature, nutrients and contaminants that would not be spread in the way they are. LÄS MER
