    Auxin controls a range of growth related characteristics by a mechanism dependent upon polar auxin transport. We have identified a leaf vein patterning mutant that shows a simple first leaf vein pattern. The veins are ...
  • Ahmadi, Morteza; University of Lethbridge. Faculty of Arts and Science (Lethbridge, Alta. : University of Lethbridge, Faculty of Arts and Science, 2006Arts and SciencePhysics, 2006)
    In this thesis, aspects of the physics of black holes are reviewed and new results in black hole thermodynamics are presented. First, general black hole solutions of Einstein’s equations of general relativity are mentioned ...
  • VandenBerg, Penny M.; University of Lethbridge. Faculty of Arts and Science (Lethbridge, Alta. : University of Lethbridge, Faculty of Arts and Science, 2002Arts and ScienceDepartment of Pyschology, 2002)
    The time course of peri-infarct diaschisis following a focal ischemic infarct and the effects of delayed rehabilitation on behavioral and functional recovery were examined. Intracortical microstimulation (ICMS) was used ...

    Fourier transform spectroscopy (FTS) is one of the premier ways to collect source information through emitted radiation. It is so named because the principal measurement technique involves the analysis of spectra ...
  • Chapman, Ian Myles; University of Lethbridge. Faculty of Arts and Science (Lethbridge, Alta. : University of Lethbridge, Faculty of Arts and Science, 2002Arts and ScienceDepartment of Physics, 2002)
    The performance of astronomical interferometer arrays operating at (sub) millimeter wave-lengths is seriously compromised by rapid variations of atmospheric water vapour content that distort the phase coherence of incoming ...
  • White, Patricia; University of Lethbridge. Faculty of Arts and Science (Lethbridge, Alta. : University of Lethbridge, Dept. of Kinesiology, c2009Arts and ScienceDepartment of Kinesiology, 2009)
    The purpose of this thesis was to compare the contributions of attentional resources relevant to postural control between fall-fearful and non-fearful older adults. Levels of postural challenge and instructions of task ...
  • Garrett, Jasmine Jay Tamara; University of Lethbridge. Faculty of Arts and Science (Lethbridge, Alta. : University of Lethbridge, Faculty of Arts and Science, 2005Arts and ScienceDepartment of Biological Sciences, 2005)
    The development of leaf vascular patterns is a highly regulated process. The plant hormone auxin is critical for vascular patterning: auxin canalization is proposed to cause files of cells to accumulate higher auxin ...
  • Gergel, Barry; University of Lethbridge. Faculty of Arts and Science (Lethbridge, Alta. : University of Lethbridge, Faculty of Arts and Science, 2007Faculty of Arts and ScienceDepartment of Mathematics and Computer Science, 2007)
    A new automatic compression scheme that adapts to any image set is presented in this thesis. The proposed scheme requires no a priori knowledge on the properties of the image set. This scheme is obtained using a unified ...
  • Mlynarski, Angela; University of Lethbridge. Faculty of Arts and Science (Lethbridge, Alta. : University of Lethbridge, Faculty of Arts and Science, 2006Arts and ScienceDepartment of Mathematics and Computer Science, 2006)
    A digital library is a collection of services and information objects for storing, accessing, and retrieving digital objects. Automatic text summarization presents salient information in a condensed form suitable for user ...
  • Kolla, Maheedhar; University of Lethbridge. Faculty of Arts and Science (Lethbridge, Alta. : University of Lethbridge, Faculty of Arts and Science, 2004Arts and ScienceDepartment of Mathematics and Computer Science, 2004)
    Summarization is a complex task that requires understanding of the document content to determine the importance of the text. Lexical cohesion is a method to identify connected portions of the text based on the relations ...
  • Waite, Wendy Lou; University of Lethbridge. Faculty of Arts and Science (Lethbridge, Alta. : University of Lethbridge, Faculty of Arts and Science, 2003Arts and ScienceDepartment of Neuroscience, 2003)
    This thesis examined the role of exogenous basic fibroblast growth factor (FGF-2) in stimulating recovery after early cortical injury. Rats with medial prefrontal cortex (MFC), posterior parietal cortex (PPC), or sham ...
  • Monfils, Marie-H.; University of Lethbridge. Faculty of Arts and Science (Lethbridge, Alta. : University of Lethbridge, Department of Psychology and Neuroscience, 2005Arts and ScienceDepartment of Neuroscience, 2005)
    Basic fibroblast growth factor (FGF-2) is a trophic molecule involved in a number of functions within the central nervous system (CNS), including a prominent role in the regulation of CNS responses to injury. Prior studies ...
  • Rowntree, Sharon R.; University of Lethbridge. Faculty of Arts and Science (Lethbridge, Alta. : University of Lethbridge, Faculty of Arts and Science, 1995Arts and ScienceDepartment of Psychology, 1995)
    Basic fibroblast growth factor (bFGF) has been implicated in the brain's trophic response to injury. This thesis examined the effects of endogenous bFGF on brain plasticity and recovery of behavioral function following ...
  • Hardy, Jared C.; University of Lethbridge. Faculty of Arts and Science (Lethbridge, Alta. : University of Lethbridge, Faculty of Arts and Science, 2007Arts and ScienceDepartment of Neuroscience, 2007)
    Conventional cylinder test measures have limited sensitivity in determining hemiparkinson rat forelimb use asymmetry and approximating substantia nigra (SN) dopaminergic neuron loss. This thesis investigates which cylinder ...
