Diet Similarity Of Pen-Raised Versus Native, Louisiana White-Tailed Deer In Southeastern Louisiana, Kristopher Scott Davis Jan 2003

Diet Similarity Of Pen-Raised Versus Native, Louisiana White-Tailed Deer In Southeastern Louisiana, Kristopher Scott Davis

LSU Master's Theses

Previous studies have shown that pen-raised deer may be already predisposed to malnutrition at a higher rate then their native counterparts because they are normally raised on a pelleted ration and may not forage efficiently once released into wild habitats. Therefore, twenty pen-raised white-tailed deer that were offspring of deer obtained from Missouri (Odocoileus virginianus) were released onto a marsh pump-off habitat in southeast Louisiana (Da Bunch) to compare their diets to the diets of the native, wild, white-tail deer population already established in the area over four consecutive seasons to test this hypothesis. The microhistological analysis technique was used …

Rhizome Manipulation Affects Growth And Development Of Ornamental Gingers, Maria Del Pilar Paz Jan 2003

Rhizome Manipulation Affects Growth And Development Of Ornamental Gingers, Maria Del Pilar Paz

LSU Master's Theses

Ornamental gingers are popular cut flowers and have been promoted as a promising potted flower crop because of unique foliage, long-lasting colorful bracts, and few pest problems. Rhizomes are the primary means of propagation in late spring followed by shoot growth and flowering, and plants enter dormancy under short days in the fall. Termination of dormancy is important for greenhouse forcing and extending the growing season. Rhizomes of five ginger species (Curcuma alismatifolia Gagnep., C. cordata L., C. roscoeana Wallich, Globba winittii C.H.

Evaluation Of Mechanical Fitness For Service Of High Temperature Hydrogen Attacked Steels, Brent Matthew Saba Jan 2003

Evaluation Of Mechanical Fitness For Service Of High Temperature Hydrogen Attacked Steels, Brent Matthew Saba

LSU Master's Theses

A novel approach is introduced in evaluating one of industry’s most complex corrosion phenomena, high temperature hydrogen attack (HTHA). Limited efforts have been made by industry to address this degradation mechanism and even less data are available to properly utilize their evaluation techniques. The predominant fracture mechanics based analysis of HTHA relies on Charpy V-Notch (CVN) impact test data. In the face of limited CVN test data, accurate results are shaky at best. The HTHA evaluation set forth in this paper combines the analysis tools of plastic collapse and both static and dynamic fracture mechanics. The first condition addresses plastic …

A Disjoining Pressure For Small Contact Angles And Its Applications, Qingfang Wu Jan 2003

A Disjoining Pressure For Small Contact Angles And Its Applications, Qingfang Wu

LSU Master's Theses

A thin liquid film experiences additional intermolecular forces when the film thickness h is less than roughly 100 nm. The effect of these intermolecular forces at the continuum level is captured by the disjoining pressure . Since dominates at small film thicknesses, it determines the stability and wettability of thin films. To leading order, a thin film can be treated as uniform and . This form, however, cannot be applied to films with non-zero contact angles. A recent ad-hoc derivation to include the slope leads to a that allows a contact line to move without slip.

Numerical Solution Of Ocular Fluid Dynamics, Satish Kumar

LSU Master's Theses

Numerical calculations of the aqueous humor dynamics in the anterior chamber of both the rabbit and the human eye are presented to delineate the basic flow and transport mechanisms. The calculations are based on a geometrical model of the eye, which represents the Trabecular mesh (TM) as a multi-layered porous zone of specified pore sizes and void fraction. Buoyancy is observed to be the dominant driving mechanism for the convective motion in both orientations (horizontal and vertical) of the eye. Reducing the TM pore size does not appear to have a significant influence on the intra-ocular pressure (IOP) until the …

Helen M. Turner, American Impressionist, Maia Jalenak

LSU Master's Theses

A renewal of interest in the French impressionists began in 1974 with the 100th anniversary of the first exhibition of the artists who broke with the official Salon in Paris and held their own exhibitions from 1874 through 1886. Since 1974, there has been a swell of interest in reinvestigating lesser-known European and American impressionist artists, especially women artists whose work often was relegated to second-class professional status. Among them was Helen Maria Turner (1858-1958), an artist whose work merits further examination. In the first two decades of the twentieth century, Turner's art was held in great esteem by critics, …
