  1. 6. REMOVAL OF LIPOPHILIC EXTRACTIVES AND MANGANESE IONS FROM SPRUCE TMP WATER BY FLOTATION

    Författare :Dariusz Zasadowski; Magnus Norgren; Anna Sundberg; Mittuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Flotation; Foaming agents; Chelating surfactant; TMP process water; Pitch control; Internal cleaning stage;

    Sammanfattning : Dissolved and Colloidal substances (DisCo) and metals are released from wood during thermomechanical pulp (TMP) production. The mechanical treatment causes that these components have a tendency to accumulate in process waters, as the water circulation systems in integrated paper mills are being closed. LÄS MER

  3. 7. Cell response to imaging contrast agents suggested for atherosclerotic plaque imaging

    Författare :Amit Laskar; Ximing Yuan; Wei Li; Rolf GG Andersson; Eva Hurt-Camejo; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : Oxysterols are the major cytotoxic components of oxidized low-density lipoprotein (OxLDL) that accumulate in atherosclerotic plaques. Their uptake by macrophages ensue foam cell formation, atherogenesis and plaque progression. LÄS MER

  4. 8. Ellipsometry studies of liquid interfaces: New methodology and applications

    Författare :Jan-Willem Benjamins; Fysikalisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Surface and boundary layery chemistry; Ytkemi; gränsskikt; phospholipids; lactoglobulin; air water; oil water; block copolymers; nonionic surfactants; Brewster angle microscopy; Ellipsometry; adsorption;

    Sammanfattning : Adsorption of several surface active agents, such as nonionics, diblock copolymers, triblock copolymers, proteins and phospholipids at the oil/water and air/water has been studied. In order to be able to do this, a new ellipsometry setup, which utilizes light guides, was developed and tested. LÄS MER

  5. 9. Surfactant metabolism in the newborn : the impact of ventilation strategy and lung disease

    Författare :Kajsa Bohlin; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Surface active agents; pulmonary surfactant; respiratory distress syndrome; stable isotope; artificial respiration; continuous positive airway pressure; metabolism; rabbit; compliance; preterm; newborn;

    Sammanfattning : Developmental deficiency in pulmonary surfactant leads to respiratory distress syndrome (RDS) in preterm infants, but all newborns may have impaired surfactant metabolism secondary to lung disease or ventilator induced lung injury. Exogenous surfactant treatment is usually administered in conjunction with mechanical ventilation. LÄS MER

  7. 10. Nano- and Micro-sized Molecularly Imprinted Polymer Particles on Solid Surfaces

    Författare :Tripta Kamra; Synkrotronljusfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Molecularly imprinted polymers (MIPs) are artificial receptors made by imprinting template molecules in a polymer matrix followed by their removal through washing to obtain a specific and selective template cavities. This property of the MIPs have made them a very efficient material for diverse applications such as chromatography, purification, drug sensing, etc. LÄS MER
