  • Performance and graphics enhancement of the LOGSIM mechanized log harvesting system simulator

    Creator:
    Moss, J. Alexander
    Abstract:
    The focus of this research concentrates on enhancement of the LOGSIM mechanized log harvesting system simulator. Enhancement of software focuses on overall improvement of the user environment as well as improvement of the performance and capabilities of the simulation package. An enhanced version of the front-end interface program is developed...

  • Permineralized Mesozoic Moss Gametophytes and their Implications for Bryophyte Evolution

    Creator:
    Bippus, Alexander C.
    Abstract:
    Mosses (Phylum Bryophyta) are widely considered to be among the most ancient groups of land plants (embryophytes) and they are the second most speciose embryophyte phylum with ~13,000 extant species. Despite their diversity and antiquity, mosses have a limited fossil record, which primarily consists of gametophytes entombed in Cenozoic amber....

  • The Alexander polynomial

    Creator:
    Scherich, Nancy
    Abstract:
    The Alexander polynomial is a well understood classical knot invariant with interesting symmetry properties and recent applications in knot Floer homology. There are many different ways to compute the Alexander polynomial, some involving algebraic techniques and others more geometric or combinatorial approaches. This is an interesting example of how different...

  • The effects of plant population and nitrogen on sweet corn yields

    Creator:
    Moss, Joe Dick
    Abstract:
    The response of sweet corn (Zea mays L. var. rugosa cultivar Jubilee) to 12 populations and four nitrogen rates was studied in a field experiment. Populations ranged from 43, 904 to 329,800 plants/ha with nitrogen levels ranging from 0 to 224 Kg/ha. A systematic spacing design was used. Plant height,...

  • Life-Cycle and Playability Analysis of Natural Turfgrass and Synthetic Infill Playing Surfaces Under Field Conditions

    Creator:
    Daviscourt Brian L.
    Abstract:
    The perception of a long-term cost advantage of synthetic infill turf systems relative to natural grass systems has contributed to a rise in their popularity in the USA. However, few comprehensive cost assessments of natural grass and synthetic infill systems exist. There are also no studies looking at interactions between...

  • Assimilate production and partitioning in wheat

    Creator:
    Mkamanga, Godwin Yindoli
    Abstract:
    Studies on net carbon exchange, ¹⁴ C assimilation, and growth analysis were done on four cultivars of high yielding soft white winter wheat (Triticum aestivum L. em Thell), Anza/Sturdy, Hill- 81, Stephens, and Yamhill, which differ in morphology, maturity, and yield, to see if differences in production and distribution of...

  • Modeling phyllochron in wheat and barley

    Creator:
    Cao, Weixing
    Abstract:
    An understanding of the effect of environment on phyllochron (degree-days between two successive leaves) is necessary to model cereal crop canopy growth. This study was designed to investigate the relationships of phyllochron to temperatures and daylengths in winter wheat (Triticum aestivum L.) and spring barley (Hordeum vulgare L.). A series...

  • Integrating real-time weather data with dynamic crop development models

    Creator:
    Donaldson, William S.
    Abstract:
    Crop development models are commonly used in research. However, their use as crop management tools for growers is rare. Decision support systems (DSS), which combine crop models with expert systems, are being developed to provide management assistance to growers. Researchers at Oregon State University are in the process of developing...

  • The effect of water injection at seeding in dry soil on the germination and growth of winter wheat (Triticum aestivum L.)

    Creator:
    Noori, Fariborz
    Abstract:
    Stand establishment plays a significant role in the development and yield of winter wheat (Triticum aestivum L.). Availability of soil moisture to the germinating seed is one of the most critical factors affecting stand establishment. Water injection is a method of applying supplemental moisture to the soil in direct contact...
