  2. 1. Tracking changes in dissolved natural organic matter composition : evaluating drinking water production using optical and molecular level tools

    Author : Elin Lavonen; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : 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. READ MORE

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

    Author : Gunnar Sjörs; Uppsala universitet; []
    Keywords : 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;

    Abstract : 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. READ MORE

  5. 3. Innovative treatment technologies for PFAS-contaminated water - Utilizing foam partitioning and exploring electrochemical oxidation

    Author : Sanne Smith; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The presence of per- and polyfluoroalkyl substances (PFAS) in the aquatic environment has become a global cause for concern. PFAS are persistent anthropogenic chemicals, and certain PFAS are known to be mobile, bioaccumulative and toxic. READ MORE

  6. 4. Water oxidation : From Molecular Systems to Functional Devices

    Author : Quentin Daniel; Licheng Sun; Marc Robert; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Water oxidation; Renewable energy; Electrochemistry; EPR; Devices; Molecular system; Characterization; Kemi; Chemistry;

    Abstract : The production of hydrogen gas, through the process of water splitting,is one of the most promising concepts for the production of clean andrenewable fuel.The introduction of this thesis provides a brief overview of fossil fuelsand the need for an energy transition towards clean and renewable energy.

  7. 5. 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
