The Significance Of Beta-72 Asparagine Methylation In C-Phycocyanin., Beth Ann Thomas Jan 1993

The Significance Of Beta-72 Asparagine Methylation In C-Phycocyanin., Beth Ann Thomas

LSU Historical Dissertations and Theses

A novel post-translationally modified asparagine, $\gamma$-N-methylasparagine (NMA), has been characterized at the $\beta$-72 site in many phycobiliproteins. The behavior of a NMA-containing peptide under Edman degradation conditions employed for sequence analysis was examined; NMA can be reproducibly identified in protein sequences by careful attention to repetitive yields and the presence of minor peaks. The effects of asparagine methylation on photosynthetic rates in the cyanobacterium Synechococcus PCC 7942 and two methylase-minus mutants was measured by steady-state oxygen evolution in whole cells. The methylase-minus mutants demonstrated lower rates of electron transfer through Photosystem II under conditions in which phycobilisomes were preferentially illuminated …

Structures Of And Allelic Diversity And Relationships Among The Major Outer Membrane Protein (Ompa) Genes Of The Four Chlamydial Species, B. Kaltenboeck, K. G. Kousoulas, J. Storz Jan 1993

Structures Of And Allelic Diversity And Relationships Among The Major Outer Membrane Protein (Ompa) Genes Of The Four Chlamydial Species, B. Kaltenboeck, K. G. Kousoulas, J. Storz

Faculty Publications

DNA sequences coding for 81% of the ompA gene from 24 chlamydial strains, representing all chlamydial species, were determined from DNA amplified by polymerase chain reactions. Chlamydial strains of serovars and strains with similar chromosomal restriction fragment length polymorphism had identical ompA DNA sequences. The ompA sequences were segregated into 23 different ompA alleles and aligned with each other, and phylogenetic relationships among them were inferred by neighbor-joining and maximum parsimony analyses. The neighbor-joining method produced a single phylogram which was rooted at the branch between two major clusters. One cluster included all Chlamydia trachomatis ompA alleles (trachoma group). The …

Glycine And Alanine Supplementation Of Culture Medium Enhances Development Of In Vitro Matured And Fertilized Cattle Embryos, K. Moore, K. R. Bondioli Jan 1993

Glycine And Alanine Supplementation Of Culture Medium Enhances Development Of In Vitro Matured And Fertilized Cattle Embryos, K. Moore, K. R. Bondioli

Faculty Publications

One-cell cattle embryos were prepared by in vitro oocyte maturation and fertilization (IVM/IVF) and cultured with or without oviductal cells. Embryos were evaluated after 7 days in culture to determine the percentage developing from the 1-cell stage to the morula or blastocyst stage. The combination of glycine (2 mM) and alanine (1 mM) with oviductal cells (experiment 1) improved embryo development over that in control culture (29 vs. 13%; p < 0.05). An optimum response was obtained with 10 mM glycine and 1 mM alanine in coculture (experiments 2 and 3). In experiment 4, the effects of glycine (0 or 10 mM), alanine (0 or 1 mM), and the presence or absence of oviductal cells were tested. In the absence of oviductal cells, the addition of glycine, alanine, or glycine and alanine combined improved embryonic development over that in control medium (45, 33, 42 vs. 24%, p < 0.001, p < 0.05, p < 0.001, respectively). However, the effect of the combination of glycine and alanine was not different from that of glycine alone when oviductal cells were absent (42 vs. 45%, p > 0.10). In the presence of oviductal cells, glycine or the combination of glycine and alanine improved embryonic development over that in the control medium with cells (47, 55 vs. 37%, …

Response Of Early Lactation Cows To Fat Supplementation In Diets With Different Nonstructural Carbohydrate Concentrations, James C. Coomer, Henry E. Amos, Cathy C. Williams, Jeffrey G. Wheeler Jan 1993

Response Of Early Lactation Cows To Fat Supplementation In Diets With Different Nonstructural Carbohydrate Concentrations, James C. Coomer, Henry E. Amos, Cathy C. Williams, Jeffrey G. Wheeler

Faculty Publications

Twenty-four high producing (36.7 kg/d, initially) Holstein cows in early lactation were used in a 63-d lactation trial to study the effects of low (28%), medium (31%). and high (37%) nonstructural carbohydrate concentrations in diets with added fat. Diets with isonitrogenous (17% CP) and fed as TMR with 41% sorghum silage. Nonstructural carbohydrate concentrations were altered by substitution of corn gluten feed and soybean hulls (50:50) for wheat and corn in the concentrate portion of the diet. Fat was added at 3% of DM in the form of yellow grease. Production of milk (38.5, 38.9, and 40.4 kg/d) and 3.5% …

Windows To Critical Thinking: Perspectives On Pedagogy In Henry James's "The Bostonians", Carson Mccullers's "The Heart Is A Lonely Hunter", And Frederick Douglass's "Narrative Of The Life Of Frederick Douglass, An American Slave"., James Thomas Mullane Jan 1993

Windows To Critical Thinking: Perspectives On Pedagogy In Henry James's "The Bostonians", Carson Mccullers's "The Heart Is A Lonely Hunter", And Frederick Douglass's "Narrative Of The Life Of Frederick Douglass, An American Slave"., James Thomas Mullane

LSU Historical Dissertations and Theses

Many times teachers restrict students to viewing literature through a single "preferred" window or from a rather small set of tiny windows, thus hindering their ability to think critically and make choices for themselves. It is my contention that our pedagogy should facilitate a "school of windows" in which students are offered many different vantage points from which to "see" literature--an environment which, instead of monologically conditioning them to accept content without criticism or question, dialogically allows them their own place and importance in active discourse. This study delineates the power that literature has to enable students to acquire these …

The Absent Father In Modern Drama., Paul Nagim Rosefeldt Jan 1993

The Absent Father In Modern Drama., Paul Nagim Rosefeldt

LSU Historical Dissertations and Theses

Theories of modern drama point out the powerful sense of loss and alienation that is woven into the very fabric of modern drama. This sense of loss is connected with the death of God and the destruction of absolute value systems. This study, however, takes the theory of loss one step further, tying the absence of God in modern drama to the absence of the father. The psychoanalytical theories of Sigmund Freud, Jacques Lacan, and Carl Jung view the father as a disembodied presence standing above and outside of culture. These psychological theories of the father can be connected to …

Nitrogen Composition And Feeding Value Of Annual Forages As Affected By Nitrogen Fertilization And Defoliation Frequency., Youbo Zhang Jan 1993

Nitrogen Composition And Feeding Value Of Annual Forages As Affected By Nitrogen Fertilization And Defoliation Frequency., Youbo Zhang

LSU Historical Dissertations and Theses

Initially, various solvents were tested for their efficacy in isolating soluble nitrogen (SN) from annual ryegrass and berseem clover. Plant nitrogen (PN) solubilities were similar in.5 M NaCl, autoclaved rumen fluid, borate phosphate buffer and Burroughs' solution. The mean PN solubilities across forages ranged from 12% for.1 M acetic acid to 45% for.2% NaOH. At 4$\sp\circ$C, 15% TCA precipitated the most soluble plant protein nitrogen (SPPN). Nitrogen (N) yield, concentrations of PN, SN, SPPN and soluble nonprotein nitrogen (SNPN) increased linearly as N fertilization (NF) increased from 0 to 335 kg N/ha. Decreasing defoliation interval (DI) from 6- to 2-wk …

Structural Analysis And Methionine Ehancement Of The Bean Seed Storage Protein Phaseolin., John M. Dyer Jan 1993

Structural Analysis And Methionine Ehancement Of The Bean Seed Storage Protein Phaseolin., John M. Dyer

LSU Historical Dissertations and Theses

Common beans are widely utilized as a food source, yet are limited as a complete source of protein due to low levels of methionine, an essential amino acid for humans. A protein engineering strategy was developed to increase the methionine content of phaseolin, the primary seed storage protein in common beans. The engineering strategy consists of three major parts. In the first part, a set of biophysical probes was developed to characterize the stability of wild-type and modified phaseolin proteins. I used absorbance, fluorescence emission, circular dichroism, and fluorescence polarization anisotropy to monitor phaseolin denaturation induced by urea, guanidinium chloride, …

Relationship Between Vegetation And Soil Formation In A Rapidly Submerging Coastal Marsh, J. A. Nyman, R. D. Delaune, H. H. Roberts, W. H. Patrick Jan 1993

Relationship Between Vegetation And Soil Formation In A Rapidly Submerging Coastal Marsh, J. A. Nyman, R. D. Delaune, H. H. Roberts, W. H. Patrick

Faculty Publications

In a Terrebonne Basin (Louisiana) marsh, Cs dating indicated that vertical accretion (0.98cm yr ) was extremely rapid relative to other marshes, but insufficient to counter submergence (1.38cm yr ). Mineral and organic matter accumulation were similar to that in other marshes. This marsh is threatened by a positive feedback loop of plant flooding stress and inadequate vertical accretion. Inadequate plant growth limits vertical accretion, which further increases flooding and decreases plant production. Thus plant production partly determines the degree of submergence some coastal and estuarine marshes will tolerate. -from Authors 137 -1 -1

The Poetry In-Between: Presence And Absence In Whitman, Rimbaud, And Hopkins., Jonathan Flint Alexander Jan 1993

The Poetry In-Between: Presence And Absence In Whitman, Rimbaud, And Hopkins., Jonathan Flint Alexander

LSU Historical Dissertations and Theses

"The Poetry In-Between: Presence and Absence in Whitman, Rimbaud, and Hopkins" analyzes three major nineteenth-century poets and their development of a poetics which has as its chief focus of concern the issue of presencing an eternal and universal "Other" by which to assess self identity. After the Kantian critique and the seeming reduction of human knowledge to phenomenal perceptions, early nineteenth-century poets and theorists feared the entrapment and isolation of the self in subjective awareness. The romantics, such as Friedrich Schlegel, sought ways to overcome such alienating subjectivity and ultimately conceived of the poet as a privileged spokesman and arbiter …

Peasant Subsistence In Northwestern Haiti: Geography, Cultural Ecology, And Rural Development., Edward Cameron Britton Jan 1993

Peasant Subsistence In Northwestern Haiti: Geography, Cultural Ecology, And Rural Development., Edward Cameron Britton

LSU Historical Dissertations and Theses

Geographers are challenged to explain "the why of where." This study grapples with "whys" of peasant subsistence in contemporary rural Haiti. Cultural ecology, one of the fundamental themes in cultural geography, examines the interplay between cultural traditions and the realities of subsistence in a given physical environment. Haitian cultural traditions derive from a rich melange of folkways from West Africa, Indian Middle America, and Western Europe. The land is semiarid and hilly in Northwestern Haiti, the poorest, driest, and most sparsely settled of Haiti's provinces. Crops and livestock betray traditional preferences in foodways, and reveal much about the constraints of …

A Southern Social Ethic: Political Economy In The Nineteenth-Century South. Mississippi, 1840-1910. (Volumes I And Ii)., Bradley G. Bond

LSU Historical Dissertations and Theses

As a study of the southern social ethic, this work discusses some of the most lasting themes of southern historiography: race and class, continuity and discontinuity. The social ethic might best be defined as a collection of ideas, at times contradictory, that suggest southerners' concepts of life in a good republic, citizenship, and proper economic behavior. It also examines the reality of life in a rural state as it experienced the process of modernization. The first third of the dissertation offers a definition of the social ethic. Liberty and virtue, white southerners believed, inhered in all who avoided enslavement, the …

New Approaches And Techniques For Drawing Lines On Raster Devices., Philip Arthur Graham Jan 1993

New Approaches And Techniques For Drawing Lines On Raster Devices., Philip Arthur Graham

LSU Historical Dissertations and Theses

Two basic approaches to drawing lines on raster devices are discussed and improved upon. The first is the recursive bisection algorithm, a method recently proposed by John Rankin, which uses a fractal approach to draw lines. The second is the double-step algorithm, a method proposed by Xiaolin Wu and Jon Rokne, which is based on the traditional Bresenham approach to drawing lines. Although a number of line drawing algorithms exist, the algorithms presented are of interest because the double-step algorithm is one of the fastest line drawing algorithms. Furthermore, since lines are self-similar and fractals have been found to be …

Disclosure Decisions And Patterns After A Near-Death Experience., Regina M. Hoffman Jan 1993

Disclosure Decisions And Patterns After A Near-Death Experience., Regina M. Hoffman

LSU Historical Dissertations and Theses

As a dimension of privacy regulation, self-disclosure is the means through which individuals manage the psychological boundary area between the inner, private world and the outer, public world of interaction with others. In communication research, a gap has been noted between self-disclosure as defined by scientific method and self-disclosure as it is experienced by people in their daily life. This study reduces that gap by investigating disclosure decisions about a major life experience through the thick perspectives of the individuals themselves. Disclosure is examined as a context-embedded communicative process. To provide a thick description of disclosure decisions, an ethnographic methodology …

The Death Of A Dialect: Brule Spanish In Ascension Parish, Louisiana., Charles Edward Holloway Jan 1993

The Death Of A Dialect: Brule Spanish In Ascension Parish, Louisiana., Charles Edward Holloway

LSU Historical Dissertations and Theses

The goals of this dissertation are: (1) to describe the Brule dialect, (2) to investigate aspects of language death, and (3) to provide important information to the area of Hispanic dialectology. The vestigial Spanish dialect spoken by the Brule dwellers of Ascension Parish, Louisiana is at the brink of linguistic extinction. The "Brule dwellers" have remained isolated from other Spanish-speaking groups since they arrived in Louisiana from the Canary Islands in the late 1700's. The specific phonological, morphological and syntactic characteristics of this unique variety of Spanish are documented here. Although the close relationship of Brule Spanish to the dialects …
