  2. 1. Computational Studies of the Temperature Dependence of Enzyme Catalysis

    Author : Florian van der Ent; Johan Åqvist; Hugo Gutierrez de Teran; Nigel Richards; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Enzymes are known to adapt to low temperatures by lowering the enthalpy of activation of the key reaction steps. A lesser known property of some psychrophilic (cold-active) enzymes is an anomalous temperature optimum. READ MORE

  4. 2. Forest-savanna transitions: Understanding adaptation and resilience of the tropical forest ecosystems using remote sensing

    Author : Chandrakant Singh; Ingo Fetzer; Lan Wang-Erlandsson; Ruud van der Ent; Stefano Manzoni; Udita Sanga; Vivian Ribeiro; Stockholms universitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Environmental Sciences; miljövetenskap; Ecology and Evolution; ekologi och evolution; Hydrology; hydrologi;

    Abstract : Climate and deforestation-induced changes in precipitation drive tropical forest-savanna transitions. However, precipitation alone provides a superficial understanding of the underlying mechanism behind these transitions. This is because our knowledge of how vegetation responds to changes in hydroclimate is fragmented. READ MORE

  5. 3. Rooting for forest resilience : Implications of climate and land-use change on the tropical rainforests

    Author : Chandrakant Singh; Ingo Fetzer; Lan Wang-Erlandsson; Ruud van der Ent; Axel Kleidon; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Climate change; forest dynamics; human influence; land-use change; rainforest tipping; remote sensing; resilience; root zone storage capacity; tropical forests; vetenskap om hållbar utveckling; Sustainability Science;

    Abstract : Tropical rainforests in the Amazon and Congo River basins and their climate are mutually dependent. Evaporation from these forests help regulate the regional and global water cycle. Furthermore, these rainforests themselves depend on precipitation to sustain their structure and functions. READ MORE

  6. 4. Training-induced increase in mitochondrial biogenesis

    Author : Emma Hawke; Department of Neurological and Movement Sciences University of Verona; []
    Keywords : alkalosis; acidosis; muscle adaptation; PGC1alpha; cell signalling;

    Abstract : Endurance training leads to an improved ability of muscle to utilize oxygen. This is related to an increased density and function of mitochondria. READ MORE

  7. 5. Synthesis and Energy Transfer Studies of a Donor-Host-Acceptor Triad

    Author : Jerker Mårtensson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; orientation factor; self-assembly; porphyrin; cations; F #246; rster; dimer; donor-host-acceptor triad; energy transfer; degenerate transition; diaza-crown ether;

    Abstract : This dissertation describes the synthesis of a donor-host-acceptor triad, D-H-A, and its self-assembly into a well-ordered dimer. The energy transfer (EnT) properties of D-H-A as it is, in the presence of a variety of guest molecules and in the dimeric form are presented. READ MORE
