  • Nonlinear internal waves on the continental shelf

    Creator:
    Shroyer, Emily L.
    Abstract:
    The properties and evolution of nonlinear internal waves (NLIWs) depend upon the background conditions within which waves form, propagate, and dissipate. As a result, the NLIW field on the New Jersey shelf displayed dramatic variability during the Shallow Water 2006 experiment. Wave variability was exhibited by 1) amplitudes that ranged...

  • The Ecophysiology of Thiamine Deficiency Complex : Evaluating Sources of Thiaminase in Great Lakes Food Webs

    Creator:
    Evans, Allison N.
    Abstract:
    Thiamine (vitamin B₁) is required by all living organisms for carbohydrate metabolism and synthesis of amino acids. Thiamine deficiency is responsible for several related classes of early life stage mortality disorders in salmonines, including Thiamine Deficiency Complex (TDC) in the Laurentian Great Lakes, Cayuga Syndrome in the Finger Lakes, and...

  • The biology and control of reed canarygrass (Phalaris arundinacea L.) on irrigation ditchbanks

    Creator:
    Comes, R. D. (Richard Durward), 1931-
    Abstract:
    Reed canarygrass (Phalaris arundinacea L.) is a desirable pasture grass on wet areas in the Northern United States and Southern Canada, but it is a serious and troublesome ditchbank weed in the Pacific Northwest and Rocky Mountain States. The purpose of this study was to learn more about the development,...

  • Predicting School Readiness Using Motor Skill Proficiency of At-Risk Preschoolers

    Creator:
    Tepfer, Amanda Taek Soon
    Abstract:
    Background: Early childhood is filled with incredible growth in all areas of development and offers a critical period for optimal learning (Lerner, 2002). During this critical period both motor skills (Bouffard, Watkinson, Thompson, Causgrove Dunn, & Romanow, 1996; Clark & Metcalfe, 2002; Lubans, Morgan, Cliff, Barnett, & Okely, 2010; Stodden...

  • Nitrogen nutrition of seedling alfalfa (Medicago sativa L.)

    Creator:
    Eardly, Bertrand D.
    Abstract:
    Nitrogen fertilization of seedling legumes is a controversial practice intended to provide N to the plant during periods when seed N, soil N, and N₂ fixation may not meet plant requirements; eg. prenodulation, postharvest, or in the event of an inoculation failure. Field experiments were conducted in 3 consecutive years...

  • Urea release from sulfur-coated urea and nitrogen utilization by tall fescue

    Creator:
    Pettygrove, G. Stuart
    Abstract:
    Sulfur-coated urea (SCU), a slow release nitrogen fertilizer, may be economically competitive with conventional fertilizers, but little is known of the mechanism of urea release from SCU and the environmental factors which affect the urea release rate. Objectives of this thesis were: (1) to determine factors which affect the rate...

  • Protein Disorder in the Evolution of Dynein Regulation

    Creator:
    Jie, Jing
    Abstract:
    Intrinsically disordered proteins (IDP) are a class of proteins that lack a three-dimensional structure and their prevalence and diverse functions in the cell have only been discovered relatively recently. The intermediate chain (IC) subunit of the microtubule motor protein complex dynein contains an N-terminal disordered region, N-IC, which is central...

  • Flavor chemistry of irradiated milk fat

    Creator:
    Khatri, Lakho Lilaram
    Abstract:
    Increasing interest has been shown in the irradiation sterilization and irradiation pasteurization of foods, but problems of off-flavors and odors are still unsolved, especially in the case of dairy products. From the flavor chemistry point of view, milk lipids are very highly susceptible to irradiation effects. Therefore, this investigation was...
