Genetics Of Stalk And Seed Quality Traits In Maize (Zea Mays L.) With Lfy Gene., Sridhar Dronavalli Jan 1992

Genetics Of Stalk And Seed Quality Traits In Maize (Zea Mays L.) With Lfy Gene., Sridhar Dronavalli

LSU Historical Dissertations and Theses

Parenchyma cell death (PCD) in stalk internodes of maize (Zea mays L.) is related to stalk rot. Spread of stalk rotting fungi is restricted by living parenchyma cells. A previously reported correlation coefficient of 0.70 between leaf midrib cell death (LMCD) and PCD indicated that selection for LMCD might result in low PCD, thus improving stalk quality. Inheritance of PCD and LMCD in maize possessing the leafy (Lfy) gene needs to be investigated. Experiments were conducted in three environments to estimate general (GCA) and specific combining ability (SCA) effects for PCD and LMCD via a diallel cross among seven Lfy …

Cultural Studies And The Multicultural Curriculum., Mary Susan Huddleston Edgerton Jan 1992

Cultural Studies And The Multicultural Curriculum., Mary Susan Huddleston Edgerton

LSU Historical Dissertations and Theses

Although some of the most recent work in the field of multicultural education has acknowledged and begun to theorize about what has been called the new cultural politics of difference, problems concerning the very notions of marginality, boundaries, and their accompanying "essentialist" thought remain undertheorized. It is my intention to bring discussions about marginality and essentialism from literary theory, feminist psychoanalytic theory and poststructuralist philosophy more explicitly into the conversation about multicultural curriculum theorizing. In this study I have attempted to further develop this conversation around notions of "translation" as generated by philosophers Michel Serres (1982) and John Rajchmann (1991) …

Effects Of Hydrologic Alterations On The Vegetation And Soils Of Marshes In Southern Louisiana., Kathryn Marie Flynn Jan 1992

Effects Of Hydrologic Alterations On The Vegetation And Soils Of Marshes In Southern Louisiana., Kathryn Marie Flynn

LSU Historical Dissertations and Theses

Hydrology is the primary forcing function in wetlands. Therefore, alterations to hydrology, which can result from either natural or anthropogenic causes, can have dramatic effects on wetland structure and function. Structural marsh management, one type of anthropogenic alteration, employs levees and water control structures to reduce or reverse wetland loss and enhance the productivity of natural renewable resources. Its use is becoming increasingly popular in southern Louisiana as a solution to the problem of marsh deterioration despite the fact that very line comprehensive data is available on the effectiveness of this practice. Associated with the use of structural marsh management …

Making The Secular Sacred: An Analysis Of Linguistic Devices Used To Give Religious Perspective To Ordinary Events., Wayne Porter Gregory Jan 1992

Making The Secular Sacred: An Analysis Of Linguistic Devices Used To Give Religious Perspective To Ordinary Events., Wayne Porter Gregory

LSU Historical Dissertations and Theses

It has been suggested that human beings do not possess social reality so much as they actively and cooperatively construct it by means of language in interaction with others. The manipulation of symbols, the creation of inferences, the posturing of one's personal identity all work together to enable participants (both speakers and hearers) in a given speech event to create social reality and reaffirm and maintain their social relationships. In religious speech communities, like the one investigated in this study, participants seek to create a different kind of social reality--one that encompasses all of the individual and corporate experiences of …

Incorporating Reservoir Characteristics For Automatic History Matching., Keith J. Halford Jan 1992

Incorporating Reservoir Characteristics For Automatic History Matching., Keith J. Halford

LSU Historical Dissertations and Theses

Automatic history matching is refined in this work by expanding the objective function and incorporating reservoir characteristics in the process of parameter selection. Iso-value contours are used to incorporate reservoir characteristics within history-matching parameters. These improvements are implemented in an automatic history-matching algorithm, OPTIM, that is coupled with BOAST II. Case histories of both hypothetical and real reservoirs demonstrated the effectiveness of incorporating reservoir characteristics in automatic history-matching parameters.

Effects Of Heat And Iron Fractions On Lipid Oxidation In Meat., Dongmei Han Jan 1992

Effects Of Heat And Iron Fractions On Lipid Oxidation In Meat., Dongmei Han

LSU Historical Dissertations and Theses

Size exclusion (SE) and hydrophobic interaction (HIC) high performance liquid chromatography (HPLC) methods were developed for determining hemoglobin, myoglobin, and total pigments in beef and chicken. Hemoglobin and myoglobin in beef, but not in chicken, were separated by HIC with minimum detectable levels of 0.187 and 0.085 $\mu$g/$\mu$l, respectively. Determination of total pigment by SE-HPLC (minimum detection of 0.001 $\mu$g/$\mu$l) was more sensitive than with spectrophotometric assay. The effects of heat at 55$\sp\circ$C, 70$\sp\circ$C, 85$\sp\circ$C, and 100$\sp\circ$C on the distribution of iron in six fractions (water-soluble, water-insoluble, diffusate, hematin, total heme, and ferritin) in beef and chicken muscles were determined. …

Development Of A Portable And Selective Volatile Organic Compound Analyzer Based On An Enhanced Microchip Gas Chromatograph., Aaron Meleki Mainga Jan 1992

Development Of A Portable And Selective Volatile Organic Compound Analyzer Based On An Enhanced Microchip Gas Chromatograph., Aaron Meleki Mainga

LSU Historical Dissertations and Theses

Although the use of portable gas chromatographs is a well established technique, it is still experiencing rapid growth. For continued growth and acceptance, however, it must be a viable alternative over the use of traditional gas chromatographs, in terms of its applicability for identification of important compounds, and its routine use for the analysis of volatile organic compounds (voc) in ambient air. The biggest limitation to the use of portable gas chromatographs is their lack of sensitivity to low concentrations of voc's. Most portable gas chromatographs at present have a detection limit of about 1 ppmv, while the concentration of …

Structural, Immunological, And Functional Characterization Of Simian Immunodeficiency Virus Proteins., Mark Anton Miller

LSU Historical Dissertations and Theses

Biochemical, immunological, and structural characterizations of the structural proteins of simian immunodeficiency virus (SIV) were performed. Various electrophoretic and chromatographic analyses of native and metabolically radiolabeled virus preparations coupled with immunological procedures such as Western blotting and radioimmunoprecipitation were utilized to identify SIV/DeltaB670-encoded polypeptides. Two-dimensional tryptic peptide mapping of each putative viral protein was employed to confirm that each of these components were unique and not cleavage products of precursor polyproteins. Site-directed serological studies using synthetic peptides analogous to regions of the SU and TM protein predicted to have high antigenic potential were performed. These studies resulted in the identification …

Analysis Of Protein Factors Involved In Transport Of The Precursor Of The Small Subunit Of Ribulose-1,5-Bisphosphate Carboxylase/Oxygenase Into Intact Chloroplasts., Steven Mark Pomarico

LSU Historical Dissertations and Theses

Two protein factors involved in the transport of precursor proteins into intact chloroplasts have been examined. The first of these was observed in experiments utilizing fusion proteins containing various lengths of wheat pS fused to CaM. Transport experiments with these fusion proteins demonstrated a requirement for transport of a pS/CaM fusion protein of a portion of mature S greater than 4 amino acids. Additionally, when the CaM portion of a fusion protein adopted a stable conformation by binding Ca$\sp{2+}$, a larger portion of mature S was needed for efficient transport. A second protein factor was examined using DIDS, and the …
