Historic Changes In Channel Morphology Of Mississippi River Tributaries: Southwestern Mississippi., Elaine Grace Yodis Jan 1990

Historic Changes In Channel Morphology Of Mississippi River Tributaries: Southwestern Mississippi., Elaine Grace Yodis

LSU Historical Dissertations and Theses

This study assesses the geomorphological changes to the fluvial systems of two rivers in southwestern Mississippi that have been foreshortened. Channel foreshortening in the lower reaches of these rivers is similar to a lowering of base level and causes a steepening of the channel gradient which leads to channel incision, bank erosion and increased sediment load. Analysis of historical and modern data and a comparison with three unmodified rivers in the same physiographic region, provide an estimate of the magnitude and rate that such disturbances are transmitted through the fluvial system. Degradation and channel instability of the Homochitto River and …

Role Of Polyamines In Dna Synthesis Of Catharanthus Roseus Cells Grown In Suspension Culture, Rakesh Minocha, Subhash C. Minocha, Atsushi Komamine, Walter C. Shortle Jan 1990

Role Of Polyamines In Dna Synthesis Of Catharanthus Roseus Cells Grown In Suspension Culture, Rakesh Minocha, Subhash C. Minocha, Atsushi Komamine, Walter C. Shortle

Faculty Publications

The requirement for polyamines in the proliferation of cells was first demonstrated in bacteria (3). While significant progress has been made in this field using animal cell cultures, only preliminary studies have been reported with plant tissues. Serafini-Fracassini et al. (9) showed a marked increase in polyamine synthesis early during the G 1 phase, concomitant with the synthesis of RNA, following the break of dormancy in Helianthus tuberosus tuber tissue. A second phase of polyamine accumulation began during the progression of S phase. Torrigiani et al. (10) and Phillips et al. (7) later showed that all major polyamines peaked during …

Influence Of Storage Temperature And Duration On Deterioration Of Film-Wrapped And Non-Wrapped Mustard, Brassica Juncea Coss., Regina Poillion Bracy Jan 1990

Influence Of Storage Temperature And Duration On Deterioration Of Film-Wrapped And Non-Wrapped Mustard, Brassica Juncea Coss., Regina Poillion Bracy

LSU Historical Dissertations and Theses

Mustard "greens' is a popular fresh vegetable, especially in the South. Fresh market production, however, is restricted to local sales or short-distance markets due to the relatively short shelf life of mustard. Packaging has been shown to successfully extend the shelf life of several fruits and vegetables. To determine the effect of packaging and storage temperature on the postharvest life and quality of mustard, mustard was stored at 1, 4, and 15C in perforated polyethylene bags, Cryovac D-955 60-gauge or 100-guage heat-shrinkable films or not-wrapped. A preliminary experiment was conducted with spinach to develop experiment methodology and for comparison of …

Root Growth, Root Function, And Water Relations Of Shortleaf Pine (Pinus Echinata Mill.) Bare-Root Seedlings Transplanted Into Different Edaphic Environments., John Closs Brissette Jan 1990

Root Growth, Root Function, And Water Relations Of Shortleaf Pine (Pinus Echinata Mill.) Bare-Root Seedlings Transplanted Into Different Edaphic Environments., John Closs Brissette

LSU Historical Dissertations and Theses

Root growth and its effects on water uptake and plant water relations of seedlings during the initial weeks after transplanting were studied. One-year old bare-root shortleaf pine seedlings were put into six different root zone environments defined by the factorial arrangement of two temperatures and three levels of soil water potential. Needle water potential and stomatal conductance were measured 28 days after planting. The next day, root system absorptive capacity was evaluated by forcing water at a constant hydrostatic pressure through detopped seedlings. The projected surface area of old and new roots was then measured. Also, the relative water content …

A History Of Rudimental Drumming In America From The Revolutionary War To The Present., Eric Alan Chandler Jan 1990

A History Of Rudimental Drumming In America From The Revolutionary War To The Present., Eric Alan Chandler

LSU Historical Dissertations and Theses

Rudimental drumming gained significance in America during the period of the Revolution. Ever since the late eighteenth-century and through the nineteenth-century, it was used exclusively in the military. This study traces the migration of drum rudiments and their use in military settings from Great Britain to America. The contributions of the Swiss drummers and the incorporation of their drum music into American rudimental drumming are also examined. The introductory chapter covers related pertinent and prefatory topics such as a definition of rudimental drumming, the duties of the military drummer, non-rudimental types of drumming and a summary of the origin and …

Palynological And Carbon-Isotopic Techniques For Reconstruction Of Paleomarsh Salinity Zones., Gail Lois Chmura Jan 1990

Palynological And Carbon-Isotopic Techniques For Reconstruction Of Paleomarsh Salinity Zones., Gail Lois Chmura

LSU Historical Dissertations and Theses

Palynological and carbon-13 analyses were studied to determine their practicality as tools for paleoecological reconstruction of marsh vegetation communities of the Mississippi delta plain. Both were calibrated on marsh surface sediment samples from four vegetation zones within Barataria Basin, Louisiana: fresh, intermediate, brackish and salt marsh. Samples were taken concurrent to vegetation sampling to allow comparison of sediment data to plant biomass and clip plot data from each of the four zones. The $\partial\sp{13}$C of sedimentary carbon reflects the proportion of C-3 and C-4 species at a site (which corresponds to a salinity gradient in the basin). The average from …

The Dynamical Behavior Of Rodlike Polymers In Concentrated Solutions., Larry Mark Delong Jan 1990

The Dynamical Behavior Of Rodlike Polymers In Concentrated Solutions., Larry Mark Delong

LSU Historical Dissertations and Theses

In chapter One, zero angle depolarized light scattering methods for particle size determinations are demonstrated by a study on aqueous colloidal suspensions of titanium dioxide. Previous results on a poly(tetrafluoroethylene) latex suspension are also briefly recounted and updated to include reanalysis by an additional independent Laplace inversion method, Provencher's CONTIN. Size distributions may be obtained by Laplace inversion of the correlation functions, with excellent agreement among the various Laplace inversion algorithms. Resolution is greatly enhanced, since rotational motions, which are more sensitive to size than translational motions, are detected at zero angle. In Chapter Two, combined static and quasielastic light …

Estimation Of Additive And Heterotic Direct And Maternal Genetic Effects For Carcass Traits In Beef Steers., Sidney Marc Derouen Jan 1990

Estimation Of Additive And Heterotic Direct And Maternal Genetic Effects For Carcass Traits In Beef Steers., Sidney Marc Derouen

LSU Historical Dissertations and Theses

Carcass measurements were taken on straightbred and crossbred steers to estimate least squares means and heterosis (1,494 steers) and, to partition additive and heterotic genetic effects (1,536 steers) on hot carcass weight (HCWT), retail yield (YIELD), ribeye area (REA), fat thickness (FT), marbling score (MS) and Warner-Bratzler shear (WBS). Steers were produced over four generations in a rotational crossbreeding study and consisted of Angus (A), Brahman (B), Charolais (C) and Hereford (H) breeds. Two-, three- and four-breed rotation systems were generated with the restriction that each breed combination include the B. Straightbreds were maintained as controls. Treatment, mating system and …

Seasonal And Daily Variations In Plasma Hormone Concentrations Of The Gulf Killifish, Fundulus Grandis., Arnil Cabading Emata Jan 1990

Seasonal And Daily Variations In Plasma Hormone Concentrations Of The Gulf Killifish, Fundulus Grandis., Arnil Cabading Emata

LSU Historical Dissertations and Theses

Circadian rhythms of hormone secretion and responsiveness to hormones were examined in the gulf killifish. The findings provide additional information to support the hypothesis that reproductive, metabolic and behavioral activities are regulated in part by a temporal interaction of circadian rhythms. These findings include: (1) Daily injections of drugs that influence serotonergic (5-hydroxytryptophan, 5-HTP) and dopaminergic (dihydroxyphenylalanine, DOPA) activities induce conditions appropriate to either summer or winter, and can determine the manner in which a fish reacts reproductively and metabolically to water temperature, the main environmental determinant. (2) Tryptophan-enriched diets stimulated increases in plasma triiodothyronine and somatomedin-C levels, dramatically stimulated …

Late Quaternary Foraminifera Of The Northwestern Gulf Of Mexico. (Volumes I And Ii)., Richard Allen Denne Jan 1990

Late Quaternary Foraminifera Of The Northwestern Gulf Of Mexico. (Volumes I And Ii)., Richard Allen Denne

LSU Historical Dissertations and Theses

A study of distribution patterns of benthic foraminifera from the Recent and late Pleistocene northwestern gulf of Mexico revealed a close relationship between assemblages and water masses. Multivariate analyses (cluster and factor) of species-frequency data from 120 core tops (87-1361 m) show that the assemblages are associated with the Surface Mixed Layer, Gulf Water, Oxygen Minimum Water, Subantarctic Intermediate Water, Caribbean Midwater, and the Mississippi River outflow. A similar study of 61 samples (283-1341 m) from the last glacial (15,000 yBP) delineated the boundaries of the late Pleistocene bathyal water masses. These were (in estimated paleodepths) the Subtropical Underwater (100?-350 …

The Legal Status Of The Unborn After Webster, Jeffrey A. Parness Jan 1990

The Legal Status Of The Unborn After Webster, Jeffrey A. Parness

Faculty Articles, Papers, and Other Scholarship

The recent U.S. Supreme Court decision in Webster v. Reproductive Health Services, as well as recent advances in our understanding of human reproduction, has prompted new dialogue on the legal status of the unborn and on the level of legal protection appropriate for potential human life. In joining the dialogue, this commentary is prompted by several concerns. First, the landmark decision in Roe v. Wade has frequently been misunderstood, creating much confusion over the permissible boundaries of protecting potential human life. A debate about laws pertaining to the unborn must be founded upon a proper understanding of what the Supreme …

Observations On Recent Efforts To Deter Frivolous Papers In The Illinois Circuit Courts, Jeffrey A. Parness Jan 1990

Observations On Recent Efforts To Deter Frivolous Papers In The Illinois Circuit Courts, Jeffrey A. Parness

Faculty Articles, Papers, and Other Scholarship

Recently, significant legislative initiatives have been made to deter the filing of frivolous papers in the Illinois Circuit Courts. These initiatives authorize the imposition of sanctions on those who file litigation papers determined to be without adequate support. The 1986 amendments to section 2-611 of the Illinois Code of Civil Procedure and the 1989 Illinois Supreme Court's adoption of Rule 137 represent the most significant of these legislative initiatives. These changes in Illinois law were comparable to the procedural law changes effected recently for many other state trial courts and for the federal district courts. This nationwide outburst of change …

Prospective Fathers And Their Unborn Children, Jeffrey A. Parness Jan 1990

Prospective Fathers And Their Unborn Children, Jeffrey A. Parness

Faculty Articles, Papers, and Other Scholarship

While significant national attention has recently been paid to varying questions about the legal duties of prospective mothers to their unborn children, little comparable focus has been placed on the duties of prospective fathers. Why the difference? Though men and women obviously participate differently in nurturing the development of potential human life, there is much that both prospective parents can do to promote the well-being of their future offspring. This inattention to male responsibilities not only undercuts prevailing governmental interests in protecting potential life, but also may, at times, constitute prohibited sex discrimination. When attention has been paid to prospective …

Design Of High Performance Soft X-Ray Windows, Raymond T. Perkins, David D. Allred, Larry V. Knight, James M. Thorne Jan 1990

Design Of High Performance Soft X-Ray Windows, Raymond T. Perkins, David D. Allred, Larry V. Knight, James M. Thorne

Faculty Publications

X-ray windows are used in sources and detectors to separate the neighborhood of the x-ray generation or detection from the use environment. While each use has its own requirements, there are some principles that should be used in designing an optimal x-ray window. Because x-rays are absorbed to some extent by all materials, minimizing absorption is one criterion in preparing windows. Also, for most uses there is a pressure difference across the window so that ensuring pinhole-free structure and sufficient mechanical strength to support the differential is another criterion for window design. Traditionally, absorption is minimized by fabricating the window …
