Development Of Various Quantitative And Analytical Methods For The Analysis Of The Dynamics Of Fish Populations: An Application To The Spotted Seatrout Population In Coastal Louisiana., Thomas Earl Helser Jan 1992

Development Of Various Quantitative And Analytical Methods For The Analysis Of The Dynamics Of Fish Populations: An Application To The Spotted Seatrout Population In Coastal Louisiana., Thomas Earl Helser

LSU Historical Dissertations and Theses

Presented in this dissertation are analytical and quantitative methods developed for an experimental gillnet sampling program for the analysis of the dynamics of fish populations, illustrated here on Louisiana's spotted seatrout population. Chapter 1 presents a new method of estimating gillnet selectivity using a system of simultaneous equations and a non-linear iterative maximum likelihood approach. The model solution is a set of parameter estimates which mathematically describe the response surface of capture probabilities for fish of size-class j in mesh size i. As an extension to the nonlinear maximum likelihood gillnet selectivity model, Chapter 2 presents a second approach using …


Genetic And Systematic Study Of Viviparus Georgianus (Lea), A Freshwater Snail Species Complex., Masaya Katoh Jan 1992

Genetic And Systematic Study Of Viviparus Georgianus (Lea), A Freshwater Snail Species Complex., Masaya Katoh

LSU Historical Dissertations and Theses

Genetic and morphological variation were studied in a brooding (ovoviviparous) and morphologically variable freshwater snail (Viviparus georgianus (Lea)) in the southeastern United States. Eleven populations were clustered into three genetically isolated, allopatric species characterized by 7 to 15 diagnostic loci out of the 38 loci examined. These allopatric species were an eastern species (in eastern and southern Florida), a western species (in the Florida panhandle), and a central species in the Ochlockonee River. Nei's standard genetic distances between species were large (0.23-0.52) compared to within-species distances (0.00-0.06). Moreover, genetic distances between the Ochlockonee River species and other species were larger …


Phylogenetic Systematics Of The Ulvophyceae (Chlorophyta) Based On Cladistic Analyses Of Ribosomal Rna Genes And Morphology., Frederick William Zechman Jan 1992

Phylogenetic Systematics Of The Ulvophyceae (Chlorophyta) Based On Cladistic Analyses Of Ribosomal Rna Genes And Morphology., Frederick William Zechman

LSU Historical Dissertations and Theses

Cladistic analyses of non-molecular and nuclear-encoded rRNA sequence data provided the basis for hypotheses of relationships for the green algal class Ulvophyceae. Non-molecular data rooted with Chara support hypotheses which group the Chlorophyceae and Pleurastrophyceae with ulotrichalean and ulvalean Ulvophyceae. Analyses of rRNA sequence data group the siphonous and siphonocladous Ulvophyceae (i.e. Caulerpales, Siphonocladales, and Dasycladales) with the Chlorophyceae and Pleurastrophyceae. Although hypotheses supported by these independent data sets are incongruent, they suggest that the Ulvophyceae is not monophyletic. Based on rRNA sequences, pleurastrophycean taxa, which, like the Ulvophyceae, possess a counter-clockwise arrangement of flagellar basal bodies, are more closely …


Effects Of Vertebrate Herbivory On Louisiana Coastal Marshes., Katherine Lynn Taylor Jan 1992

Effects Of Vertebrate Herbivory On Louisiana Coastal Marshes., Katherine Lynn Taylor

LSU Historical Dissertations and Theses

The disturbances of herbivory, simulated "eat-outs" (clipping and removal of above-ground biomass), and burning were examined for their effect on total biomass, individual species abundance, and species richness in several different marsh communities. Herbivory significantly reduced the total community biomass of all the marshes studied. Simulated "eat-outs" reduced the total biomass of the freshwater marsh but had no persistent effect on the total biomass of either the oligohaline or mesohaline marshes of the Pearl River. Both the oligohaline and the mesohaline marshes were able to recover from a removal of above-ground biomass (simulated "eat-out") within two years. The freshwater marsh …


Autobiographical Amnesia: Memory, Myth, Curriculum., Gregory Michael Nixon Jan 1992

Autobiographical Amnesia: Memory, Myth, Curriculum., Gregory Michael Nixon

LSU Historical Dissertations and Theses

Autobiography in curriculum theory and practice is being more and more acknowledged as a major force leading toward the development of reflectively analytical teachers, reflexive practitioners, and discursively self-aware individuals. I look to two vital aspects of self-narration to explore. I speak firstly of memory, without which narrative continuity would be impossible. Memory is as involved with learning as it is with storytelling, and I would agree with Krell (1978) that "inquiry into memory and the theory of pedagogy go hand in hand" (p. 131). I eschew the models of memory provided by the behavioral sciences, empirical psychology, cognitive psychology, …


Structure And Light-Induced Expression Of A Small Heat-Shock Protein Gene Of Pharbitis Nil, Priti Krishna, Roderick F. Felsheim, John C. Larkin, Anath Das Jan 1992

Structure And Light-Induced Expression Of A Small Heat-Shock Protein Gene Of Pharbitis Nil, Priti Krishna, Roderick F. Felsheim, John C. Larkin, Anath Das

Faculty Publications

To isolate genes that are regulated by a photoperiod that promotes flowering in Pharbitis nil, a cDNA library representing mRNA of induced cotyledons was screened by differential hybridization. The DNA sequence of one cDNA clone isolated by this approach, clone 12L, showed homology to plant small heat-shock protein (hsp) genes. P. nil genomic clones hybridizing to clone 12L were isolated, and the DNA sequences of two P. nil small hsp (shsp) genes, shsp-1 and shsp-2, were determined. The derived amino acid sequences of shsp-1 and shsp-2 showed maximum homology to the 17.9-kD soybean hsp, a member of the class II …


Stress Begins In Kindergarten: A Look At Behavior During Standardized Testing, Pamela O. Fleege, Rosalind Charlesworth, Diane C. Burts, Craig H. Hart Jan 1992

Stress Begins In Kindergarten: A Look At Behavior During Standardized Testing, Pamela O. Fleege, Rosalind Charlesworth, Diane C. Burts, Craig H. Hart

Faculty Publications

Kindergarten children’s behavior before, during, and after standardized achievement testing was explored through a qualitative study in two classrooms (n = 36). Simultaneously quantitative data were collected in one of the classrooms (n = 21) before and during the testing. Data were collected through observations in the classrooms, interviews with children and teachers, and audio and video taping of the children. For the quantitative component of the study, frequencies of stress behaviors were observed using a scan sampling method. Qualitative findings indicated an increase in behaviors reported to be stress related during the testing and a decrease in those behaviors …


Continuity Of Affine Transformations Of White Noise Test Functionals And Applications, H. H. Kuo, J. Potthoff, J. A. Yan Jan 1992

Continuity Of Affine Transformations Of White Noise Test Functionals And Applications, H. H. Kuo, J. Potthoff, J. A. Yan

Faculty Publications

Translations and scalings defined on the Schwartz space of tempered distributions induce continuous transformations on the space of white noise test functionals [25]. Continuity of the induced transformations with respect to their parameters is proved. As a consequence one obtains a direct simple proof of the fact that the space of white noise test functionals is infinitely differentiable in Fréchet sense. Moreover, it is shown that the Wiener semigroup acts as a mollifier on the space of test functionals. © 1992.


Correlation Between Diverse Seismic And Physical Properties Data Sets: Site 763, Southern Exmouth Plateau, J. M. Lorenzo, E. E. Vera Jan 1992

Correlation Between Diverse Seismic And Physical Properties Data Sets: Site 763, Southern Exmouth Plateau, J. M. Lorenzo, E. E. Vera

Faculty Publications

Five major reflectors in multichannel seismic common-depth-point line 667 (acquired with an airgun source), single-channel seismic ODP line 5 (acquired with a high-resolution watergun), and expanded spread profile C2 can be dated and tied to lithologic units. Through an initial τ-sum construction, followed by traveltime and full waveform forward modeling, ESP-derived compressional wave velocities can more accurately match traveltimes of these reflectors than full-reflectivity synthetic seismograms produced from shipboard-derived properties. Instrument calibration, drilling disturbance, and rebound effects suffered by the laboratory samples are sources of error. The authors speculate, based on the physical properties of the units that reflector "b' …


Emergence Of Radiation From Gravitational Potential Wells: The Absence Of Ωm Effects, Richard H. Price, Jorge Pullin Jan 1992

Emergence Of Radiation From Gravitational Potential Wells: The Absence Of Ωm Effects, Richard H. Price, Jorge Pullin

Faculty Publications

We consider a source of gravitational waves of frequency ω, located near the center of a massive galaxy of mass M and radius R with ωR-1. The case of odd-parity gravitational waves propagating through a perfect-fluid galaxy is particularly simple; for this case we find that, in addition to the expected redshift of the radiation emerging from the galaxy, there is a small amount of backscatter, of order Mω2R3. We show that there is no suppression of radiative power by the factor 1+ω2M24 as has been recently predicted by Kundu. The origin of Kundu's suppression lies in the interpretation of …


Electron-Pair Analysis For Doubly Excited Ridge States, Lijun Zhang, A. R.P. Rau Jan 1992

Electron-Pair Analysis For Doubly Excited Ridge States, Lijun Zhang, A. R.P. Rau

Faculty Publications

The two-electron Schrödinger equation is analyzed in hyperspherical coordinates, with the electrons described throughout as a pair. In contrast to the current adiabatic hyperspherical method, which reverts at large distances to a description in terms of individual electrons, the pair aspect is preserved also asymptotically. Whereas the adiabatic potential wells converge to single-ionization limits, we develop potential wells converging to the double-ionization limit of the system, and doubly excited states are then viewed as eigenstates of the pair in these wells. At the simplest level, we get series converging to the double-ionization limit which are described analytically by the pair-Rydberg …


Further Psychometric Properties Of The Mother's Activity Checklist., Linda Merideth Little Jan 1992

Further Psychometric Properties Of The Mother's Activity Checklist., Linda Merideth Little

LSU Historical Dissertations and Theses

The present study attempted to extend the results obtained by Kelley and Carper (1988) regarding the psychometric properties of the Mother's Activity Checklist utilizing a larger, more heterogeneous sample of mothers. The MAC is a 100-item checklist of pleasant and unpleasant setting events which mothers frequently experience. A revised version of the MAC consisting of 45 items was developed utilizing factor analysis procedures. The revised version consists of four factors: Pleasant Events, Unpleasant Events, Aversive Child Behavior, and Aversive Marital Events. Utilizing a sample of eight hundred and thirty-three mothers with children between the ages of 2 and 12, both …


Internal Labor Markets: Labor Process And Market Power Effects., Rebecca Grace Long Jan 1992

Internal Labor Markets: Labor Process And Market Power Effects., Rebecca Grace Long

LSU Historical Dissertations and Theses

This study contends that previous investigations into the nature of internal labor markets have been hampered by their dependence on various macro-level variables (e.g., sectors, industries, strategies) that ignore the often wide variation of employment arrangements within individual firms. It proposes that a better understanding of the employment arrangements associated with individual jobs may be gained by not only examining a job's technological components, but also the relative power of a firm's various coalitions. The data used in the reported study were acquired from the headquarters of the U.S. Bureau of Employment and Training's Occupational Field Analysis Centers in Raleigh, …


Applicability Of Bioluminescence Assay And Aerobic Bacterial Counts For The Evaluation Of Raw Milk Quality., Abdul Ghafoor Mian Jan 1992

Applicability Of Bioluminescence Assay And Aerobic Bacterial Counts For The Evaluation Of Raw Milk Quality., Abdul Ghafoor Mian

LSU Historical Dissertations and Theses

Raw milk samples were analyzed to determine the bacteriological quality by the standard plate count (SPC), adenosine-5$\sp\prime$-triphosphate (ATP) assay, preliminary incubation counts, and the psychrotrophic bacteria count (PBC). In a comparison of SPC and ATP content, an overall correlation coefficient of 0.97 was found between the two methods. The correlations between ATP content and SPC of fresh raw milk samples at zero hour and after preliminary incubating these samples at 12.8 and 15.6$\sp\circ$C for 18 hours were.96,.97, and.97, respectively. The regression coefficients for all types of milk samples were highly significant ($P <$.01). High correlation coefficients demonstrated that the ATP measurement in combination with preliminary incubation practices could be a rapid technique for the determination of bacteriological quality of milk at receiving stations and milk processing plants. Median SPC for 175 fresh raw milk samples was 36,000/ml. The bioluminescence technique is reported previously to have a good correlation with SPC in the range of 1.0 $\times$ 10$\sp5$ to 1.0 $\times$ 10$\sp{10}$ bacteria/ml. The commingled milk coming at the receiving stations sometimes have a bacterial count that is less than 1.0 $\times$ 10$\sp{5}$ bacteria/ml. A correlation coefficient of.87 was calculated between the SPC and ATP values for the overall data while lowering the SPC range from 1.0 $\times$ 10$\sp5$ to 1.0 $\times$ 10$\sp4$ bacteria/ml. This range is more practical as a quick screening of raw milk at dairy processing facilities since 81 percent of all raw milk samples fell in this range. An equation (SPC = $-$1642213 + 6751(ATP)) was developed from the combined experimental data which could estimate the SPC of raw milk samples using their ATP content. Another phase of the experiment was to ascertain if the Petrifilm$\sp{\rm TM}$ technique could be effectively used in place of agar method to estimate PBC. The correlation coefficient between the Petrifilm$\sp{\rm TM}$ and the agar plate method for both the fresh and preliminary incubated raw milk samples was.99. A high linearity of relationship shows that one method can be substituted with the other. However, the Petrifilm$\sp{\rm TM}$ technique took longer than the usual time of 25 h to develop red colonies at 21$\sp\circ$C because of the slow reduction of the dye reagent triphenyl tetrazolium chloride (TTC) at this temperature.


The Use Of Goal Setting And Contingency Contracting For Improving Children's Homework Performance., Deborah Lynn Miller Jan 1992

The Use Of Goal Setting And Contingency Contracting For Improving Children's Homework Performance., Deborah Lynn Miller

LSU Historical Dissertations and Theses

Research suggests that homework has favorable effects on learning and student achievement. However, research directed at improving homework completion and accuracy has been limited in scope. The present study examined the effects of goal setting and contingency contracting on children's homework performance. Subjects were four parent-child dyads in which the child exhibited clinically significant homework problems. Dependent variables of primary interest included direct observation of children's on-task behavior, work accuracy, and Homework Problem Checklist scores (Anesko, Schoiock, Ramirez, & Levine, 1987). Using a combination of multiple baseline and withdrawal (ABAB) designs, goal setting and contingency contracting produced significant improvements in …


Regional Comparative Advantage And Inefficiency In Production: Methodological And Empirical Issues., Barun Kanti Kanjilal Jan 1992

Regional Comparative Advantage And Inefficiency In Production: Methodological And Empirical Issues., Barun Kanti Kanjilal

LSU Historical Dissertations and Theses

The general objective of this study was to provide a methodological framework for evaluating stochastic comparative advantage of a crop in a multi-region multi-crop framework and its link with inefficiency at the firm level. In the first stage, regional comparative advantage, defined in terms of relative profitability, was theoretically analyzed on the basis of a firm's behavior under uncertainty. The empirical application involved derivation of a comparative advantage index for major crops produced in different regions of Louisiana. The results revealed heterogenous survival potential of each crop across regions. Sugarcane was found to have comparative advantage over rice and soybeans …


The Effects Of Exercise Stress On Equine Immune Function., Tammie Lee Keadle Jan 1992

The Effects Of Exercise Stress On Equine Immune Function., Tammie Lee Keadle

LSU Historical Dissertations and Theses

The physiologic demands of exercise constitute a form of stress which is accompanied by modulation of immune responses. However, numerous studies in many different model systems have failed to clearly define the effects of exercise on immunity. Furthermore, the role of the neuroendocrine system in exercise-induced immunomodulation has been largely unexplored. To address these issues, we evaluated the effect of acute exercise stress on 3 indices of immune function in horses, before and after completion of a 12 week treadmill-based physical conditioning program. In addition, we determined the effects of corticosteroids, catecholamines, beta endorphin, and adrenocorticotropic hormone on these same …


Musical Invention And Poetry In The Late Vocal Works Of Anton Webern., Melanie S. Kronick Jan 1992

Musical Invention And Poetry In The Late Vocal Works Of Anton Webern., Melanie S. Kronick

LSU Historical Dissertations and Theses

From the time of his composition of Op. 23 (1933-34) until his death, Anton Webern composed a series of important twelve-tone vocal works whose texts are drawn exclusively from the poetry of Hildegard Jone. Yet Webern scholars typically ignore the texts of these works when analyzing the scores in which the poems are embedded. My discussion shows, however, that Webern made important musical choices as a result of the poetic content of his texts. While Jone's poems are plentiful in metaphors of natural phenomena and images from German romantic poetry, I argue that they are concerned as much with poetic …


Studies On Escherichia Coli Cell Division: Overexpression, Purification, And Quantitative Determination Offtsa Protein., Haichao Wang Jan 1992

Studies On Escherichia Coli Cell Division: Overexpression, Purification, And Quantitative Determination Offtsa Protein., Haichao Wang

LSU Historical Dissertations and Theses

FtsA is an essential cell division protein which is synthesized in minute amounts in Escherichia coli. To study the effects of overexpressing ftsA on the phenotype of E. coli cells, DNA fragments encoding the ftsA gene were subcloned downstream of a lac or a tac promoter in two plasmids. High-level expression of the ftsA gene from these promoters inhibited normal cell septation and caused the cells to become long, nonseptate filaments. Continued overexpression of ftsA resulted in the filaments developing spherical bulges up to 4 um in diameter. It is suggested that these bulges may emanate from septation sites because …


Modeling Three-Dimensional Groundwater Flow And Solute Transport By The Finite Element Method With Parameter Estimation., Fang Xin Yu Jan 1992

Modeling Three-Dimensional Groundwater Flow And Solute Transport By The Finite Element Method With Parameter Estimation., Fang Xin Yu

LSU Historical Dissertations and Theses

A general, systematic and improved numerical formulation for the three-dimensional (3-D) groundwater flow and solute transport problems was derived, using the finite element method. In the numerical formulation, a hidden mistake, which has appeared in many textbooks and journal papers dealing with the advective term of the general 3-D solute transport equation, was found and corrected. Some simpler and practical expressions for the leaky boundary condition, surface flux condition, and sources and sinks were proposed. To improve the conventional formulation for the time derivatives, a combination of the Galerkin method and the collocation method was developed. A more accurate scheme …


An Investigation Of The Relationship Between Severity Of Specific Adhd Symptoms And Parent And Child Locus-Of-Control Orientation In The Expression Of Parental Stress., Esther Marie Winters Jan 1992

An Investigation Of The Relationship Between Severity Of Specific Adhd Symptoms And Parent And Child Locus-Of-Control Orientation In The Expression Of Parental Stress., Esther Marie Winters

LSU Historical Dissertations and Theses

This study investigated the effects of the child's specific ADHD symptoms, aggressive symptoms, and the parents' and child's locus of control orientation on parental stress. The frequently overlooked heterogeneous nature of the ADHD population was addressed, by assessing specific ADHD symptoms and the presence of aggressive symptomatology. Sixty boys, ages 6 to 12 years, diagnosed (using DSM-III-R criteria) as having ADHD by a licensed clinical psychologist in private practice, and their parents participated in the study. Parents were asked to sign a consent form and complete measures of parental locus of control and parenting stress. A children's locus of control …


Dialogue Journal Writing In A Foreign Language Classroom: Assessing Communicative Competence And Proficiency., Lynn Patricia Baudrand-Aertker Jan 1992

Dialogue Journal Writing In A Foreign Language Classroom: Assessing Communicative Competence And Proficiency., Lynn Patricia Baudrand-Aertker

LSU Historical Dissertations and Theses

This research studied dialogue journal writing, as it occurred between a teacher and twenty-one students in a French III high school. Results on attitude questionnaire indicated that dialogue journals helped students overcome their fear of the written form and increase their self-confidence and willingness to write. By demystifying the writing process, writing in their dialogue journals helped these students develop positive attitudes. The results on writing proficiency pre and post-tests indicated that students performed as well or better than students after four years of a foreign language in a high school setting or four semesters of college instruction. The dialogue …


Pedological Investigation Of Mangrove Soils In Relationship To Rice Management In The Republic Of Guinea., Sekou Cisse Jan 1992

Pedological Investigation Of Mangrove Soils In Relationship To Rice Management In The Republic Of Guinea., Sekou Cisse

LSU Historical Dissertations and Theses

Mangrove soils along the Guinea coast are among the most fertile and potentially suitable soils for rice production. Rice production success and feasibility is hampered by adverse soil chemistry conditions and the use of traditional farming methods. The objectives were to undertake a pedological investigation to characterize these soils during the wet and dry seasons, provide an understanding of fertility constraints, and develop a management plan to improve rice production. Seasonally and permanently flooded soils categories were recognized. Seasonally flooded soils are subjected to drainage and permanent protection from saltwater intrusion. These soils were correlated as Typic Endoaquerts, Typic Endoaquepts, …


Synthesis Of Novel Metallocenes: Asymmetric Hydrogenation Catalysts To Conductive Polymers., Mark Steven Erickson Jan 1992

Synthesis Of Novel Metallocenes: Asymmetric Hydrogenation Catalysts To Conductive Polymers., Mark Steven Erickson

LSU Historical Dissertations and Theses

The goal of this research was to synthesize conductive polymers based on repeating ferrocene units. During the course of this study, the design of the conductive polymers evolved from the initial model based on "stacked" ferrocenes where ethano bridged cyclopentadienyl rings are linked by iron(II), to the latest ferrocene-diene model where ferrocene units were linked by double bonds. In the pursuit of these elusive monomers, attempts at their synthesis led down dead-end routes, even though new molecules were synthesized. Some of these dead-ends proved productive as in the synthesis of chiral titanocene derivatives. All the work reported in this dissertation …

Monopoles And Confinement In Lattice-Gauge Theory., Vandana Singh Jan 1992

Monopoles And Confinement In Lattice-Gauge Theory., Vandana Singh

LSU Historical Dissertations and Theses

The mechanism by which quarks, believed to be the fundamental constituents of matter, are prevented from existing in the free state is still unknown. The phenomenon of quark confinement is one of the fundamental problems in physics. One of the most viable candidates for a hypothesis of confinement is the dual superconductor mechanism that likens quark confinement to the Meissner effect in superconductors. The peculiarities of quark interactions make a numerical approach to the subject a necessity, and therefore, much of the work in this area has been done through the methods of lattice gauge theory, with the simplicities afforded …


A Study On The Aquic Conditions Of Two Natraqualfs In The Coastal Plain Of Louisiana., Ariel Alejandro Szogi Jan 1992

A Study On The Aquic Conditions Of Two Natraqualfs In The Coastal Plain Of Louisiana., Ariel Alejandro Szogi

LSU Historical Dissertations and Theses

This study had the purposes of investigating the aquic conditions of two selected Natraqualfs to define the relationship between wetness and morphological properties and prediction of major soil processes. The proposed criteria for aquic conditions as defined by the International Committee on Aquic Conditions (ICOMAQ) were identified by: (i) presence of redoximorphic features, and (ii) measurement of saturation and reduction. They were used to locally verify morphological inferences used to predict the aquic conditions. Morphological properties and laboratory analysis were used to predict the periodicity and duration of saturation and reduction. Soil and ground water analyses were used to understand …


Using Independence Training To Teach Independent Living Skills To Visually Impaired Children And Youth., Marie E. Taras Jan 1992

Using Independence Training To Teach Independent Living Skills To Visually Impaired Children And Youth., Marie E. Taras

LSU Historical Dissertations and Theses

Two groups of students with visual impairments were taught various independent living skills. Five of the seven students also had a diagnosis of mental retardation. One group (three first graders) was taught the tasks of folding a shirt, making an emergency telephone call, and spreading soft foods with a knife. The other group (four young men) was taught to increase leisure skills through three different leatherwork tasks. Independence training was conducted in a group format, and included social learning components (e.g., self-evaluation, peer evaluation and reinforcement) in addition to traditional operant procedures (e.g., modeling, prompting). However, due to the presence …


A Comparison Of Language And Graphic Products Of Students From Kindergarten Classrooms Differing In Developmental Appropriateness Of Instruction., Jean Germany Mosley Jan 1992

A Comparison Of Language And Graphic Products Of Students From Kindergarten Classrooms Differing In Developmental Appropriateness Of Instruction., Jean Germany Mosley

LSU Historical Dissertations and Theses

This study examines the ways in which kindergartners from more and less developmentally appropriate classrooms negotiate the process of graphic communication. Both quantitative and qualitative aspects of this process are examined. Eighty-one kindergarten children from four classrooms were asked to tell a story both verbally and graphically. They were encouraged to include drawing, writing, or both on their paper. Then they were asked to tell the story that they had produced graphically. The children were students in one of four classrooms from a single school system that were identified as: (a) most developmentally appropriate beliefs and practices; (b) developmentally appropriate …


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 Jan 1992

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 …
