  • Biochemical and structural studies of a L-haloacid dehalogenase from the thermophilic archaeon Sulfolobus tokodaii. 

    Rye, CA; Isupov, MN; Lebedev, AA; Littlechild, JA (Springer Verlag, 2009-01)
    Haloacid dehalogenases have potential applications in the pharmaceutical and fine chemical industry as well as in the remediation of contaminated land. The L: -2-haloacid dehalogenase from the thermophilic archaeon Sulfolobus ...
  • Biodiversity in the front yard: An investigation of landscape preference in a domestic urban context 

    Kurz, Tim; Baudains, C (SAGE Publications, 2012)
    It is being increasingly recognized that the success of efforts to preserve/restore biodiversity in urban areas is highly contingent on the preferences of human urban dwellers. We investigated preference ratings for photos ...
  • Biogeography of Time Partitioning in Mammals 

    Bennie, Jonathan; Duffy, James P.; Inger, Richard; Gaston, Kevin J. (National Academy of Sciences, 2013)
    Many animals regulate their activity over a 24-h sleep–wake cycle, concentrating their peak periods of activity to coincide with the hours of daylight, darkness, or twilight, or using different periods of light and darkness ...
  • Biogeography of time partitioning in mammals. 

    Bennie, Jonathan; Duffy, James P.; Inger, R; Gaston, Kevin J. (National Academy of Sciences, 2014-09-23)
    Many animals regulate their activity over a 24-h sleep-wake cycle, concentrating their peak periods of activity to coincide with the hours of daylight, darkness, or twilight, or using different periods of light and darkness ...
  • Bioinformatic identification of novel regulatory DNA sequence motifs in Streptomyces coelicolor. 

    Studholme, DJ; Bentley, SD; Kormanec, J (BioMed Central, 2004-04-08)
    BACKGROUND: Streptomyces coelicolor is a bacterium with a vast repertoire of metabolic functions and complex systems of cellular development. Its genome sequence is rich in genes that encode regulatory proteins to control ...
  • From Bones to Biotechnology: 60 Years of New Biology in the Old World 

    Macgregor, Herbert C. (Cambridge University Press, 2010)
  • Biomechanical Response to Changes in Natural Turf during Running and Turning 

    Stiles, VH; Guisasola, IN; James, IT; Dixon, SJ (Human Kinetics, 2011)
    Integrated biomechanical and engineering assessments were used to determine how humans responded to variations in turf during running and turning. Ground reaction force (AMTI, 960 Hz) and kinematic data (Vicon Peak Motus, ...
  • Biomimetic Futures: Life, Death, and the Enclosure of a More-Than-Human Intellect 

    Johnson, ER; Goldstein, J (Routledge, 2015-03-04)
    The growing field of biomimicry promises to supplant modern industry's energy-intensive models of engineering with a mode of production more sensitively attuned to nonhuman life and matter. This article considers the ...
  • Biomimicry: New Natures, New Enclosures 

    Goldstein, J; Johnson, ER (SAGE Publications Ltd, 2015-01-16)
    Advocates of biomimicry encourage a new industrial paradigm that ostensibly leaves behind the crude violence of Francis Bacon, the domination of nature-as-machine, and a history of toxic production processes that have given ...
  • The biopolitics of animal being and welfare: dog control and care in the UK and India 

    Srinivasan, K (Institute of British Geographers / Royal Geographical Society / Wiley-Blackwell, 2013-01)
