  1. 1. Challenges and Opportunities For Safe Water Supply in Mozambique

    Detta är en avhandling från Department of Water Resources Engineering, Lund Institute of Technology, Lund University

    Författare :Nelson Matsinhe; Lunds universitet.; Lund University.; [2008]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; service quality; sustainability.; water treatment; water supply;

    Sammanfattning : In Mozambique, despite considerable investments in the promotion of drinking water supplies, the access to quality water of sufficient quantity for the majority of people is still far from optimal. Current official figures report that nearly half of the country´s population and about 45 per cent of urban residents do not have access to safe water. LÄS MER

  2. 2. Sustainable Development: Implementation in Urban Water Systems

    Detta är en avhandling från Department of Water Resources Engineering, Lund Institute of Technology, Lund University

    Författare :Ali Bagheri; Lunds universitet.; Lund University.; [2006]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Miljöteknik; pollution control; Environmental technology; Naturvetenskap; Natural science; Water resources systems; Viability loops; Urban water system; System dynamics; Sustainable development; Strategy; Social learning; Process; Principles; Indicators; Planning; Monitoring; kontroll av utsläpp;

    Sammanfattning : Popular Abstract in Swedish Hållbar utveckling är ett ofta använt begrepp, som många inte riktigt förstår eftersom det går på tvärs mot traditionella vetenskapliga begrepp som förutsägelse och styrning. Många vetenskapsmän har tolkat begreppet på sätt som gynnar den egna agendan. LÄS MER

  3. 3. Core Level Spectroscopy of Water and Ice

    Detta är en avhandling från Stockholm : Fysikum

    Författare :Dennis Nordlund; Stockholms universitet.; [2004]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; x-ray adsorption spectroscopy; photoemission spectroscopy; x-ray photoelectron spectroscopy; platinum; x-ray emission spectroscopy; density functional theory; hydrogen-bonded; H-bond; water; ice; electronic structure; excited state dynamics; proton dynamics; water adsorption; liquid water; NATURAL SCIENCES Physics; NATURVETENSKAP Fysik;

    Sammanfattning : A core level spectroscopy study of ice and water is presented in this thesis. Combining a number of experiments and spectrum calculations based on density functional theory, changes in the local valence electronic structure are shown to be sensitive to the local H-bonding configurations.

  4. 4. Tracking changes in dissolved natural organic matter composition

    Detta är en avhandling från Stockholm : Fysikum

    Författare :Elin Lavonen; Sveriges lantbruksuniversitet.; [2015]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : During the last decades, the abundance of dissolved organic matter (DOM), a complex heterogeneous mixture of organic compounds, has increased in many surface waters in Northern Europe and North America. Surface waters are widely used as raw water sources for drinking water production. LÄS MER

  5. 5. Water-Metal Surfaces Insights from core-level spectroscopy and density functional theory

    Detta är en avhandling från Stockholm : Fysikum

    Författare :Theanne Schiros; Stockholms universitet.; [2008]
    Nyckelord :water; hydroxyl; metal; surfaces; x-ray spectroscopy; density functional theory; bonding; fuel cell; kemisk fysik; Chemical Physics;

    Sammanfattning : Computational methods are combined with synchrotron-based techniques to analyze the structure and bonding of water and water plus hydroxyl at metal surfaces under UHV and at near-ambient conditions. Water-metal interaction plays a crucial role in a multitude of cosmic, atmospheric and biological phenomena as well as heterogeneous catalysis, electrochemistry and corrosion. LÄS MER
