  2. 21. Computational Studies on Homogeneous Water Oxidation Catalysts

    Author : Ge Li; Mårten S. G. Ahlquist; Moyses Araujo; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Computational studies; homogeneous; water oxidation catalysts; ruthenium; iron; mechanisms; Teoretisk kemi och biologi; Theoretical Chemistry and Biology;

    Abstract : To combat the increasing energy demand and climate change, artificial photosynthesis is a promising approach to producing renewables by storing energy into chemicals and fuels. Water oxidation, responsible for offering electrons and protons to the reduction reactions, suffers from slow kinetics. READ MORE

  4. 22. Fishing the gene pool : Genetic structure, admixture and behavioural complexity in fisheries management

    Author : Kim H. Berndt; Enhet akvatisk ekologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Fisheries management; Fishery stock; Stock discrimination; Genetic structure; Genetic admixture; Admixture zone; Stock substructure; Phenotypic divergence; Gadus morhua; Salmo trutta;

    Abstract : Prudent management of marine fish resources relies on separation and management of biologically meaningful groups of conspecifics, termed fishery stocks, often depicted as self-sustaining, spatiotemporally separated and demographically independent entities. Such stock discrimination has however proven challenging. READ MORE

  5. 23. Gut microbes and the developing brain

    Author : Tim Arentsen; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : The discovery that commensal gut microbiota can influence host development and physiology beyond the gastrointestinal (GI) tract has triggered a paradigm shift in our conceptualization of the origin of human diseases. A growing body of preclinical research has demonstrated that gut microbiota exert a modulatory role on the development and function of brain circuits involved in motor control, emotion and cognition.
