  • Preschooler's perceptions of a patio garden

    Creator:
    Upington, Deborah A.
    Abstract:
    This study sought to fill a void in research literature supporting Attention Restoration Theory (ART) and the beneficial effects of exposure to natural, green spaces. The literature predominantly discusses studies with adult and older child participants, finding that exposure to natural environments often produces an attention-restoring effect. ART has been...

  • Performance and flow stability characteristics in two-phase confined impinging jets

    Creator:
    Sabo, Michael D.
    Abstract:
    Advances in electronics fabrication, coupled with the demand for increased computing power, have driven the demand for innovative cooling solutions to dissipate waste heat generated by these devices. To meet future demands, research and development has focused on robust and stable two-phase heat transfer devices. A confined impinging jet is...

  • Microscale thermal management utilizing vapor extraction from a fractal-like branching heat sink

    Creator:
    Apreotesi, Mario A.
    Abstract:
    It is hypothesized that increases in pressure drop due to vapor generation during boiling in microchannels can be reduced by extraction of vapor at its point of inception. Ultimately, this local vapor extraction decreases the pressure drop required to drive the flow through a fractal-like branching, microchannel flow network within...

  • An experimental study of co-flow ammonia-water desorption in an oil-heated, microscale, fractal-like branching heat exchanger

    Creator:
    Mouchka, Gregory A.
    Abstract:
    An experimental study was performed in which an ammonia-water solution was desorbed within a branching fractal-like microchannel array. The solution entered in the center of a disk, and flowed out radially until discharging in to a gravity-driven separation chamber. Heat was added to the ammonia-water through a thin wall, above...

  • Perceived comfort of three styles of men's running pants

    Creator:
    Christel, Deborah A.
    Abstract:
    Athletic workout clothing is designed to help the wearer stay comfortable, cool, and dry. There are several different styles of athletic apparel available at retailers and each individual has a preference as to what is comfortable for him or her. Comfort of clothing has traditionally been related to the fabric...

  • Consequences of coumaphos and Varroa destructor on drone honey bee sperm quantity

    Creator:
    Delaney, Deborah Anne
    Abstract:
    The number of drones and genetic diversity among drones are essential components to a well mated queen. Varroa destructor preferentially parasitizes drone brood, and is thought to be responsible for the loss of feral populations that once provided additional drones for honey bee mating areas. It is necessary to use...

  • Modelling Thin Liquid Film Draining of Bubbles on Porous Media in Confined Geometry

    Creator:
    Bahm, Jared S.
    Abstract:
    The behavior of the thin liquid film formed between a bubble and hydrophobic membrane is of high interest in applications where separating two-phase mixtures is beneficial. One such application is in-situ vapor extraction heat sinks. In these systems, high heat transfer rates are accomplished by taking advantage of the high...

  • A kinematic analysis of the karate back thrust kick

    Creator:
    Cullings, Deborah Ann
    Abstract:
    The back thrust kick is a karate technique used primarily in a defensive setting. This research described the kinematic variables involved in the skilled execution of the kick. Variables examined included movement sequencing, angular position of the trunk, thigh and leg, angular velocity of the thigh and leg, linear velocity...

  • Flow characteristics of co-flowing, laminar streams in a rectangular microchannel

    Creator:
    Oak, Jason
    Abstract:
    The effects of varying flow rate ratio and Reynolds number on the momentum diffusion and flow development of two co-flowing, laminar streams in a rectangular microchannel are presented. The microchannel has an aspect ratio of approximately 16 with a width of 1006 μm and a height of 63 μm. A...

  • A study of micro-scale, fractal-like branching flow networks for reduced pumping power and improved temperature uniformity

    Creator:
    Alharbi, Ali Y.
    Abstract:
    A first generation, one-dimensional predictive model is proposed for designing heat sinks with fractal flow networks. A three-dimensional computational fluid dynamics (CFD) model is analyzed as a means for validating the model and identifying areas for improvement. Two separate CFD models were developed. One was analyzed with conjugate heat transfer...
