A geographical systems analysis of the commercial crawfish industry in south Louisiana

Creator:: Gary, Don L
Abstract:: The crawfish enterprise of South Louisiana is shown to haveexpanded as much as 18-fold since the 1950's. It is estimated(1973) that there are about 44,000 acres of managed crawfish ponds.Of the 334 ponds identified and mapped in the thesis, 231 are classedas open ponds, 45 as rice field ponds, and...

Temperature preconditioning of ryegrass (Lolium sp.) seed dormancy

Creator:: Wiesner, Loren E.
Abstract:: The purposes of this study were to determine the effects of temperature, nutrients, growth regulators, and culm detachment during seed development on ryegrass seed dormancy and weight. The effects of storage temperature on seed dormancy were also studied. Seed dormancy of annual (Lolium multiflorum Lam.) and perennial (Lolium perenne L.)...

Developing a basis for characterizing precision of estimates produced from non-probability samples on continuous domains

Creator:: Cooper, Cynthia
Abstract:: This research addresses sample process variance estimation on continuous domains and for non-probability samples in particular. The motivation for the research is a scenario in which a program has collected non-probability samples for which there is interest in characterizing how much an extrapolation to the domain would vary given similarly...

Rodeo Cowgirls : An Ambivalent Arena

Creator:: Oliver, Audra Leah
Abstract:: The term "cowboy" was closely bound to American image long before the 1990s. Rodeo claimed the image of the cowboy from the earliest contests to the latest and pledged itself to patriotism almost as early. This historical study was conducted viewing rodeo as a subculture and relating women's role in...

Comparison of head morphometric traits within five selected performance types of Quarter Horses (Equus caballus)

Creator:: Smith, Elana Morgana
Abstract:: A study was conducted to investigate if morphometric facial measurements could be utilized to differentiate five categorical performance types of Quarter Horses. The five categories being Western, Halter, English, Reining, and Cutting. The measurements were collected from 323 registered Quarter Horses representing animals who ranged in age from one year...

Statistical analysis and speciation modeling of copper in Oregon highway runoff

Creator:: Bloomquist, Don J.
Abstract:: Low levels of copper have been shown to impair the olfactory system of threatened and endangered (T&E) salmon, decreasing their predator avoidance behavior and likely increasing mortality. However, only dissolved copper (dissCu) present as the cupric ion (Cu2+) and weakly complexed species are truly bioavailable. Previous studies indicate the vast...

Covariant derivatives on null submanifolds

Creator:: Hickethier, Don
Abstract:: The degenerate nature of the metric on null hypersurfaces creates many difficulties when attempting to define a covariant derivative on null submanifolds. This dissertation investigates these challenges and provides a technique for defining a connection on null hypersurfaces in some cases. Recent approaches using decomposition to define a covariant derivative...

Message Queue Manager

Creator:: Fang, Don Y.
Abstract:: The conventional way of debugging is to examine the program's state at various points during execution. With the addition of message passing as a means of communication and synchronization in message passing programs, the state of pending message operations also needs to be examined. Current parallel debuggers or analysis tools...
