  • Advection-diffusion in inertial flow through periodically converging-diverging tubes

    Creator:
    Lambert, Adam
    Abstract:
    A direct numerical simulation of advection-diffusion in a sinusoidal tube was carried out using the commercial finite-volume code STAR-CD. The Reynolds numbers varied from Re = 0.1 to Re = 14.5. At the larger Reynolds numbers, steady-state eddies formed in the diverging sections and significantly influenced the macroscale dispersion. Long...

  • Biomolecule detection by amplified photoluminescence of germanium doped diatom biosilica

    Creator:
    Gale, Debra K.
    Abstract:
    There is significant interest in the fabrication of nano- and micro-structured silica with spatially ordered features, which exhibit enhanced optoelectronic properties with application to the next generation of display devices, semiconductors, and sensors. Currents methods of fabrication employ top down processes which use extremes of temperature, pressure, and power. There...

  • Characterizing drivers of microbial community structure and function in diverse marine sediments

    Creator:
    Graw, Michael F.
    Abstract:
    Marine sediments are one of the largest habitats for microbial life on earth. These microorganisms play critical roles in biogeochemical cycling both within the subsurface and between the sediment and water columns. However, microbial communities in sediments are highly heterogeneous and the factors defining microbial community structure and metabolic function...

  • Transcriptional networks controlled by the fatty acid regulators FAR-1 and FAR-2

    Creator:
    Bredeweg, Erin L.
    Abstract:
    Fungi are capable of growth on a wide variety of carbon sources, both living and dead. They can produce an arsenal of enzymes and transporters for harvesting sugars, polysaccharides, amino acids, lipids and micronutrients from their environments [1]. Within the nucleus of a cell, transcription factors (TF) control whether genes...
