    Sammanfattning : Living matter is built on complex dynamic systems consisting of numerus biotransformations. By exploiting the adaptive and evolutive behaviors ofmolecular matter, dynamic chemistry has developed as an important tool tounderstand the organization of nonliving matter into complex living systems.

  3. 2. Tailored Reaction Media for the Synthesis of Subvalent Cluster Compounds

    Författare :Josefin Åkerstedt; Lars Kloo; Sven Lidin; Ulf Gedde; KTH; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Chemistry; Kemi; Inorganic Chemistry;

    Sammanfattning : Different synthetic approaches and modifications to reaction media have been applied in order to find new routes to the synthesis of main-group clusters and transition metal compounds. The focus has been on the Group 15 element bismuth and the transition metal palladium. LÄS MER

  4. 3. Chlorite: Geochemical properties, Dissolution kinetcis and Ni(II) sorption

    Författare :Åsa Zazzi; Zoltan Szabo; Susanna Wold; Peter Vilks; KTH; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; chlorite; dissolution kinetics; Ni II sorption; surface complexation; Chemistry; Kemi;

    Sammanfattning : In Sweden, among other countries, a deep multi-barrier geological repository, KBS-3, is planned for the burial of nuclear waste. One of the barriers is identified as the grantic bedrock itself and in this environment chlorite is present at surfaces in fracture zones. LÄS MER

  5. 4. Pitfalls in Interpreting Umbilical Cord Blood Gases and Lactate at Birth

    Författare :Parisa Mokarami; Urogynekologi och reproduktionsfarmakologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Blood gases; metabolic acidosis; umbilical cord; round-off; delayed sampling; validation;

    Sammanfattning : Acid-base status in umbilical cord blood is an objective measure of the fetus’ exposure to and ability to handle hypoxia. The objective of this thesis was to clarify some of the methodological pitfalls in interpreting umbilical cord blood gases and lactate values at birth. LÄS MER

  7. 5. Effect of elevated pCO2 and environmental oxazepam on the behavior and physiology of teleost fish

    Författare :Laura E. Vossen; Svante Winberg; Robert Gerlai; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; fish; GABA; CO2; ocean acidification; pharmaceutical pollution; oxazepam;

    Sammanfattning : This doctoral thesis investigated the effect of two aquatic pollutants on the behavior and physiology of teleost fish: i) elevated concentrations of carbon dioxide (CO2) in the context of ocean acidification and ii) low concentrations of the anxiolytic pharmaceutical oxazepam in the context of pharmaceutical pollution.Anthropogenic emissions of CO2 are lowering the pH of the oceans.
