  1. 1. Effect of solvents during material treatment applications : tuning hydrophilicity of silicone rubber and drug loading in mesoporous silica

    Författare :Anna Hillerström; Jan van Stam; Lennart Piculell; Karlstads universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; Solvents; liquid carbon dioxide; Interpenetrating Polymer Network IPN ; silicone rubber; hydrophilic; phase domains; mesoporous silica; ibuprofen; adsorption isotherms; release; Kemi; Chemistry;

    Sammanfattning : Choosing the right solvent is critical for many industrial applications. A useful property for selection of solvents is their solubility parameters. This concept of solubility parameters is central to this thesis and has been used in two different case studies of material treatment applications. LÄS MER

  2. 2. Organic solvents and cognitive functioning. With special reference to interaction with aging

    Författare :Linda Nordling Nilson; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :Solvents; occupational; neuropsychology; cognition; aging; chronic toxic encephalopathy; follow-up studies;

    Sammanfattning : The aim of the thesis was to study cognitive functioning in patients with chronic toxic encephalopathy (CTE) and in aging workers previously exposed to organic solvents. The discriminative power of a series of cognitive tests in identifying patients with CTE was examined. LÄS MER

  3. 3. Hybrid Solvents based on Ionic Liquids/Deep Eutectic Solvents for CO2 Separation : Experiments, Modeling, Process Simulation and Evaluation

    Författare :Chunyan Ma; Xiaoyan Ji; Päivi Mäki-Arvela; Luleå tekniska universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; CO2 separation; Ionic liquids; Deep eutectic solvents; Cosolvent; Thermodynamic modeling; Process simulation and evaluation; Energiteknik; Energy Engineering;

    Sammanfattning : CO2 separation plays a vital role in reducing CO2 emissions to combat climate change, in which solvent-based absorption is widely considered the most promising technology. Many conventional chemical and physical solvents have been introduced for CO2 separation, still facing challenges. LÄS MER

  4. 4. On the occurrence and possible causes of motor neuron disease in Sweden

    Författare :Lars-Gunnar Gunnarsson; Linköpings universitet; []
    Nyckelord :Epidemiology; amyotrophic lateral sclerosis; incidence; prevalence; mortality; cluster; Iisk factors; occupation; environment; agricultural work; electrical work; welding; solvents; heredity; MEDICINE; MEDICIN;

    Sammanfattning : A series of investigations have been performed to study secular trends of motor neuron disease (MND) morbidity and mortality in Sweden, to identify time and/or space clusters, if any, and to uncover risk factors. The occurrence of the disease was estimated from incidence, prevalence and mortality rates, and the strength of various determinants was evaluated by means of the case-control approach, using population controls.

  5. 5. Selective Separation Of Wood Components In Internal Process Waters Originating From Mechanical Pulping

    Författare :Dariusz Zasadowski; Magnus Norgren; Bjarne Holmbom; Mittuniversitetet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; flotation; foaming agents; chelating surfactant; TMP process water; pitch control; internal cleaning stage; hemicellulose recovery; anti‐solvents; solvents; precipitation;

    Sammanfattning : Dissolved and Colloidal substances (DSC) and metals are released from woodduring thermomechanical pulp (TMP) production. These components have atendency to accumulate in process waters, as the water circulation systems inintegrated paper mills are closed. LÄS MER
