  2. 6. Water in roads: Flow paths and pollutant spread

    Author : Hedi Rasul; B. Olofsson; Helen Kristine French; KTH; []
    Keywords : 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;

    Abstract : 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. READ MORE

  4. 7. Topical formulations, design and drug delivery : "A dive into water"

    Author : Abdullah Ali; Marie Lodén; Anan Yagmur; Anders Hall; Malmö universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; water; topical formulations; Pickering emulsion; skin cream; drug delivery; tactile friction; sensory panel; nasal; buccal; mucosa; skin; triglycerides; ethanol; drug transport; cosmetic appeal;

    Abstract : Water is a vital component regulating the properties of topical formulations and their interaction with biological barriers, such as skin and mucosa. Changing the watercontent within the frame of the pharmaceutical triangle will have a huge impact on which type of formulation, such as a cream, ointment, gel, or lotion, is formed, as well as the physical properties of the formulation.

  5. 8. Heat and water flows in freezing and thawing soils : numerical modelling, laboratory and field observations

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

    Abstract : A laboratory study of infiltration rates into frozen and unfrozen fine sand, including temperature effects of both soil and infiltration water, is reported. The average infiltration rate varied from about 10.6 mm/min for unfrozen conditions, to about 1-2 mm/min for frozen conditions. READ MORE

  6. 9. Water transport through perinatal skin : Barrier function and aquaporin water channels

    Author : Johan Ågren; Gunnar Sedin; Gunnar Flemström; Steven B Hoath; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pediatrics; Preterm infant; Transepidermal water loss; Aquaporin; Skin biology; Hyperosmolarity; Pediatrik; Paediatric medicine; Pediatrisk medicin; pediatrik; Pediatrics;

    Abstract : While constituting a well functioning interface with the aqueous environment in utero, the skin offers a poor barrier after very preterm birth. As a result, transepidermal water loss (TEWL) is high, a fact which has important clinical consequences in these infants. READ MORE

  7. 10. Tracing water transport pathways in the coupled ocean-atmosphere system

    Author : Dipanjan Dey; Kristofer Döös; Aitor Aldama Campino; David Ferreira; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Hydrological cycle; inter-ocean atmospheric water transport; water-mass conservation; atmospheric water trajectories; overturning water-mass stream functions; atmosfärvetenskap och oceanografi; Atmospheric Sciences and Oceanography;

    Abstract : Water is the most precious substance on the Earth and thus it is important to know how it moves around and is recycled.This knowledge will be useful to formulate educated future strategies about water usage in society and also to understand the near-surface salinity contrasts in the world ocean.
