  2. 11. Nitric Oxide Reductase from Paracoccus denitrificans : A Proton Transfer Pathway from the “Wrong” Side

    Author : Ulrika Flock; Pia Ädelroth; Simon de Vries; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; denitrification; nitric oxide reductase; heme copper oxidase superfamily; divergent member; proton transfer; electron transfer; single turnover; spectroscopy; periplasm; glutamate; proton pathway; Biochemistry; Biokemi; biokemi; Biochemistry;

    Abstract : Denitrification is an anaerobic process performed by several soil bacteria as an alternative to aerobic respiration. A key-step in denitrification (the N-N-bond is made) is catalyzed by nitric oxide reductase (NOR); 2NO + 2e- + 2H+ → N2O + H2O. READ MORE

  4. 12. In the Company of Ghosts : Hauntology, Ethics, Digital Monsters

    Author : Line Henriksen; Margrit Shildrick; Nina Lykke; Jeffrey Andrew Weinstock; Linköpings universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; HUMANIORA; HUMANITIES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Hauntology; monster; ghost; spectralities; Monster Studies; feminist theory; ethics; digital media; internet; Welcome to Night Vale; Mushroom Land TV; creepypasta; Hauntologi; monster; spöke; spectralities; monster studier; feministisk teori; etik; digitala medier; internet; Welcome to Night Vale; Mushroom Land TV; creepypasta;

    Abstract : This thesis explores French philosopher Jacques Derrida’s ’hauntology’ through the lens of digital monsters and feminist theory.Hauntology – a pun on ‘ontology’ and ‘haunting’ – offers an ethics based on responsibility towards that which cannot be said to fully exist, yet has an effect on our everyday lives nonetheless.

  5. 13. Role of arginase in vascular function

    Author : Christian Jung; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Background: Nitric oxide (NO) is central for the integrity of the cardiovascular system, the maintenance of endothelial function and the protection against ischaemic heart disease. The enzyme arginase is up-regulated during ischaemia-reperfusion and by hypoxia in cell culture and animal models which might be of pathophysiological relevance since it competes with NO synthase for their common substrate arginine.

  6. 14. Assessing future effects on lake ecosystem resilience using data analysis and dynamic modelling : Modelling the effects of extreme weather events and climate warming on lakes

    Author : Jorrit P. Mesman; Bastiaan W Ibelings; Stéphane Goyette; Don C Pierson; Karsten Rinke; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Extreme events; Storms; Modelling; Climate change; Thermal structure; Phytoplankton;

    Abstract : Extreme weather events can have short-term and long-term effects on lake thermal structure, nutrient dynamics, and community composition. Moreover, changes in lake variables induced by global climate change may influence the response and recovery of lake ecosystems to extreme weather events. READ MORE

  7. 15. Kinetics of proton and electron transfer in heme-copper oxidases

    Author : Peter Lachmann; Pia Ädelroth; Örjan Hansson; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Heme-copper oxidase; electron transfer; proton transfer; nitric oxide reductase; ba3 oxidase; flow-flash; laser-flash photolysis; Biochemistry; biokemi;

    Abstract : Heme-copper oxidases are transmembrane proteins that are found in aerobic and anaerobic respiratory chains. During aerobic respiration, these enzymes reduce dioxygen to water. The energy released in the reaction is used to transport protons across a biological membrane. READ MORE
