  2. 1. Urban Water Security – Local Conditions and Regional Context : A case study of attitudes and water use behaviour in Windhoek, Namibia

    Author : Therése Sjömander Magnusson; Jan Olof Lundqvist; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; water supply; urban; water management; water demand management WDM ; vattenförsörjning; Namibia; Water in nature and society; Vatten i natur och samhälle;

    Abstract : The world is becoming urbanised. Between 1995 and 2025, it is estimated that the cities and towns of the developing world will have absorbed another two billion people. A majority of these people will be poor and settle down in the unregulated areas. READ MORE

  4. 2. Water powered percussive rock drilling : process analysis, modelling and numerical simulation

    Author : Göran Tuomas; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vattenteknik; Water Resources Engineering;

    Abstract : This thesis is devoted to problems, processes and systems related to the recently developed water powered percussive rock drilling method. The technology, which uses ordinary water to drive down-the-hole hammers, has been used to produce more than 6 million meters of blast holes within the mining industry. READ MORE

  5. 3. Water diffusion and free volume in hydrophilic polymers

    Author : Charlotte Trotzig; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physical chemistry; free volume; self-diffusion; degree of crystallinity; glass transition temperature; tensile storage modulus; surface tension; isotherm; HPMC; PEO; water; triacetin; clay; Macromolecular chemistry; dynamic mechanical analysis; Fysikalisk kemi; differential scanning calorimetry; nuclear magnetic resonance; positron annihilation; Makromolekylär kemi;

    Abstract : During moisture uptake in polymers, the diffusion of the water molecules is believed to occur via unoccupied voids. These voids are called free volume cavities and their sizes are continuously altered when the moisture content in the polymer is enhanced. READ MORE

  6. 4. Development of Novel In Situ Microscopy Techniques for the Study of Water Interaction with Soft Materials

    Author : Anna Jansson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; environmental scanning electron microscopy; polymer film; manipulator; yeast cell; swelling; in situ; water transport; cellulose fibre; osmotic shock; water interaction;

    Abstract : The transport of water in soft materials can occur in liquid or gas phase and is highly dependent on the material microstructure and the structure dynamics. Understanding these relationships is the basis for the development of predictive models that can aid the design of new and improved functional materials. READ MORE

  7. 5. Resistance of Clay Brick Masonry Façades to Wind-Driven Rain : Repointing of Eroded Mortar Joints

    Author : Mohammad Kahangi; Avdelningen för Konstruktionsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; clay brick masonry façade; wind-driven rain; water absorption; water penetration; damp patches;

    Abstract : Clay brick masonry façades are commonly used due to their high-performance durability. However, exposure to climate agents such as wind-driven rain (WDR), freeze-thaw cycles, and wind abrasion cause deterioration of masonry façades over time. READ MORE
