  1. 1. Computational studies of water vapour - Liquid equilibrium

    Författare :Erik Johansson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Monte Carlo simulation; cluster; water; Gibbs ensemble;

    Sammanfattning : It is commonly known that water plays a crucial role in many natural and industrial processes. One of these processes is the formation of water trees, and the subsequent breakdown of polyethylene used for high voltage cable insulation purposes. LÄS MER

  3. 2. Observations of water vapour in the middle atmosphere

    Författare :Stefan Lossow; Jörg Gumbel; Jacek Stegman; Daniel R. Marsh; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; water vapour; mesosphere; stratosphere; dynamics; Odin satellite; limb sounding; microwave; tropics; polar winter; Meteorology; Meteorologi; meteorologi; Meteorology;

    Sammanfattning : Water vapour is the most important greenhouse gas and plays a fundamental role in the climate system and for the chemistry of the Earth's atmosphere. This thesis presents observations of water vapour in the middle atmosphere with a particular focus on the mesosphere. LÄS MER

  4. 3. Water in roads: Flow paths and pollutant spread

    Författare :Hedi Rasul; B. Olofsson; Helen Kristine French; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; De-icing salt; Road; Tracer test; ERT; Water content; Road pollutants; Flow pathways; Land and Water Resources Engineering; Mark- och vattenteknik;

    Sammanfattning : For better road construction and maintenance while minimising damage to the environment and groundwater, it is essential to monitor and model hydrological impacts on roads and consider pollution of groundwater. Water content in unbound material in road layers changes continuously and water flow usually occurs along pathways that are the main corridors for pollutant spread to groundwater. LÄS MER

  5. 4. Neonatal water and heat exchange : The influence of environmental factors and infant maturity

    Författare :Gunnar Sjörs; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pediatrics; Neonatal; transepidermal water loss; respiratory water loss; radiant heat; heat exchange; water loss; incubators; Pediatrik; Paediatric medicine; Pediatrisk medicin; pediatrik; Pediatrics;

    Sammanfattning : The environment provided by commonly used infant incubators, the effect of radiantheat and exposure to cold air on the exchange of water and heat between newborninfants and their environment, and the water loss through the skin of infants born at24-25 weeks of gestation were investigated. The evaporation of water from the skinwas measured by the gradient method. LÄS MER

  7. 5. Simulations of water clustering in vapour, hydrocarbons and polymers

    Författare :Erik Johansson; Högskolan i Borås; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cluster; gibbs ensemble; monte carlo; water; polyethylene; external field; ions; Energi och material;

    Sammanfattning : It is commonly known that water plays a crucial role in many natural and industrial processes. One of these processes is the formation of water trees, and the subsequent breakdown of polyethylene used for high voltage cable insulation purposes. LÄS MER
