Bogidiella Indica, A New Species Of Subterranean Amphipod Crustacean (Bogidiellidae) From Wells In Southeastern India, With Remarks On The Biogeographic Importance Of Recently Discovered Bogidiellids On The Indian Subcontinent, John R. Holsinger, Y. Ranga Reddy, Mohammed Messouli

Biological Sciences Faculty Publications

Bogidiella indica, new species, is described from three water wells in southeastern India, including a bore-well on the campus of Acharya Nagarjuna University in Nagarjunanagar, a water well in Guntur town, and an agricultural well in the Godavari and Krishna Basin, all in the state of Andhra Pradesh, India. The new species is assigned to the genus Bogidiella Hertzog and to a newly designated species group within the genus. Despite the near circum-global distribution of the family Bogidiellidae, only a single, partially intact specimen of a bogidiellid had been collected from the Indian subcontinent prior to the discovery of specimens …

Open-Ocean Carbon Monoxide Photoproduction, Aron Stubbins, Günther Uher, Cliff S. Law, Kenneth Mopper, Carol Robinson, Robert C. Upstill-Goddard

Chemistry & Biochemistry Faculty Publications

Sunlight-initiated photolysis of chromophoric dissolved organic matter (CDOM) is the dominant source of carbon monoxide (CO) in the open-ocean. A modelling study was conducted to constrain this source. Spectral solar irradiance was obtained from two models (GCSOLAR and SMARTS2). Water-column CDOM and total light absorption were modelled using spectra collected along a Meridional transect of the Atlantic ocean using a 200-cm pathlength liquid waveguide UV-visible spectrophotometer. Apparent quantum yields for the production of CO (AQY_CO) from CDOM were obtained from a parameterisation describing the relationship between CDOM light absorption coefficient and AQY_CO and the CDOM spectra collected. …

Effects Of Salinity Changes On The Photodegradation And Ultraviolet-Visible Absorbance Of Terrestrial Dissolved Organic Matter, E. C. Minor, J. Pothen, B. J. Dalzell, H. Abdulla, K. Mopper

Chemistry & Biochemistry Faculty Publications

We performed laboratory studies to determine the effects of salinity on the photodegradation of dissolved organic matter (DOM) from the Great Dismal Swamp, Virginia, an important source of terrestrial DOM to the lower Chesapeake Bay. Samples were created by mixing Great Dismal Swamp water (ionic strength approximate to 0 mol L^-1) with modified artificial seawater solutions of differing salinities while keeping the final dissolved organic carbon (DOC) concentration constant. These samples were then irradiated for 24 h in a light box providing ultraviolet (UV) light similar to that of natural sunlight. Light absorbance and DOC concentrations decreased after …

2-Aminoethoxydiphenyl Borate As A Prototype Drug For A Group Of Structurally Related Calcium Channel Blockers In Human Platelets, Yuliya Dobrydneva, Christopher J. Abelt, Beth Dovel, Celina M. Thadigiri, Roy L. Williams, Peter F. Blackmore

Chemistry & Biochemistry Faculty Publications

We have synthesized a series of 2-aminoethoxydiphenyl borate (2-APB, 2,2-diphenyl-1,3,2-oxazaborolidine) analogs and tested their ability to inhibit thrombin-induced Ca²⁺ influx in human platelets. The analogs were either synthesized by adding various substituents to the oxazaborolidine ring (methyl, dimethyl, tert-butyl, phenyl, methyl phenyl, and pyridyl) or increasing the size of the oxazaborolidine ring to seven- and nine-membered rings. NMR analysis of the boron-containing analogs suggests that each of them exist as a ring structure through the formation of an N -> B coordinate bond (except for the hexyl analog). The possibility that these boron-containing compounds formed dimers was also …

Role Of Hydrocarbon Pollutants, Salinity, Tidal Height, Bioenergetics And Competition In Colonization Of Oyster Reefs By Commensal Assemblages, Yasoma Dhammika Hulathduwa

LSU Doctoral Dissertations

Effects of hydrocarbons, salinity, tidal height, bioenergetics and competition on the oyster reef fauna were studied. Dried oyster shell was exposed to crude oil in the laboratory and plastic trays filled with control and oil-exposed shell were then deployed at two locations, in two seasons and at two tidal levels, with immersion periods of two and five weeks. Salinity exhibited a significant effect with sub tidal site having higher diversity. Hydrocarbon effects were less prominent. To determine effects of cleaners, Corexit 9580 was applied both alone and in combination with oil on cultch. At high concentrations, the cleaner ameliorated hydrocarbon …

Phenolic Composition And Antioxidant Activity Of Sweetpotatoes [Ipomoea Batatas (L.) Lam], Malkeet Singh Padda

LSU Doctoral Dissertations

The influence of numerous factors on sweetpotato phenolic content and antioxidant activity was determined. Simplified, robust, and rapid methodologies were developed to quantify total phenolics and individual phenolic acids in sweetpotatoes. Quantification of total phenolic content using Folin-Denis reagent provided more reliable results than Folin-Ciocalteu reagent. Individual phenolic acids were quantified by reversed-phase high performance liquid chromatography (HPLC) and the best separation was achieved using a 5-µm, 4.6 × 250 mm column with a mobile phase of 1% (v/v) formic acid aqueous solution: acetonitrile: 2-propanol (70:22:8), pH 2.5. Methanol and ethanol provided higher phenolic extraction efficiency than acetone. In general, …

Historical Fire Regimes In Southeasern Pine Savannas, Jean Marie Huffman

LSU Doctoral Dissertations

Southeastern coastal plain pine savannas lack direct evidence of past fire regimes. As a result, uncertainty exists regarding the range of variation in frequency and seasonal timing of past fire regimes and the relative importance of anthropogenic and lightning-ignited fires. Characterization of past fire regimes is needed for effective restoration and management of these high-biodiversity ecosystems. I used dendrochronologically dated fire scars from stumps of old growth longleaf pines in a large coastal, mainland pine savanna and from dead slash pines on a small, coastal barrier island in north Florida to explore past fire regimes. In the mainland savanna, 71 …

Two-Dimensional And High-Throughput Electrophoretic Separation Of Proteins Using Polymeric Microchips, Hamed Shadpour

LSU Doctoral Dissertations

A major task in proteomics is to identify proteins from a biological sample using two-dimensional (2-D) separation prior to mass spectrometry of peptides generated via proteolytic digestion of the proteins. For 2-D separations, microfluidic devices are superior to bench top and capillary-based systems since they potentially provide higher separation efficiencies due to the minimal dead volumes produced during peak transfer between the two separation dimensions. In addition, fast separations can be envisioned because the column lengths are typically shorter in microfluidic platforms without scarifying peak capacity. High-throughput capabilities are extremely desirable for many types of bio-analytical analyses, such as understanding …

Design And Evaluation Of Automated, Continuous Culture Techniques For Brachionus Rotundiformis, Zhengzhong Zhang

LSU Doctoral Dissertations

A 40-L recirculating rotifer turbidostat (RRT) pilot system consisting of a rotifer reactor, biofilter, foam fractionator, feed container, harvester, and two air-lift pumps was designed to produce B. rotundiformis, a small (S-type) rotifer, that is increasingly demanded for production of small-gape marine finfish larvae. The system’s automatic monitoring (turbidity, pH, conductivity and temperature) and controlling (turbidity, pH, feeding and harvesting) were performed by a Rugid™ computer. A 4 (temperature) x 3 (salinity) study indicated that a 30oC/15 ppt treatment is the most favorable to the growth of B. rotundiformis. Under these conditions, the effect of harvest rate on rotifer system …

Integrating Micro-Scale Separations To Matrix Assisted Laser Desorption And Ioniation Time Of Flight Mass Spectrometry (Maldi-Tof-Ms) For Protein Analysis, Harrison K. Musyimi

LSU Doctoral Dissertations

This dissertation describes the integration of micro-scale separations to matrix assisted laser desorption and ionization time-of-flight mass spectrometry (MALDI TOF MS) for protein analysis. MALDI MS provides unsurpassed accurate mass measurements of intact bio-molecules, for example peptides and proteins, which in turn generate high molecular specificity enabling the identity, function and structure of these molecules to be characterized. However, in order to realize the full potential of MS in proteomic studies, integrated sample processing on automated and high throughput platforms is required to address the complexity, diversity and the dynamic range of proteomic analysis. The work described here contributes towards …

Experimental And Computational Analysis Of Random Cylinder Packings With Applications, Wenli Zhang

LSU Doctoral Dissertations

Random cylinder packings are prevalent in chemical engineering applications and they can serve as prototype models of fibrous materials and/or other particulate materials. In this research, comprehensive studies on cylinder packings were carried out by computer simulations and by experiments. The computational studies made use of a collective rearrangement algorithm (based on a Monte Carlo technique) to generate different packing structures. 3D random packing limits were explored, and the packing structures were quantified by their positional ordering, orientational ordering, and the particle-particle contacts. Furthermore, the void space in the packings was expressed as a pore network, which retains topological and …

The Regulation Of Genes Involved In Trichome Development, Matthew Lloyd Brown

LSU Doctoral Dissertations

Arabidopsis thaliana is an organism that can be used as a model for most of the processes that occur in flowering plants. The leaf hairs, or trichomes, of Arabidopsis thaliana are macroscopic single cells that have been used as a model system for cell fate determination, cell expansion, cell cycle regulation, cell wall deposition, as well as other processes. Initiation of the trichome cell fate is controlled by a complex of genes including GLABRA1 (GL1), TRANSPARENT TESTA GLABRA (TTG), and GLABRA3 (GL3). This work examines the role of GL3 in trichome initiation and uses plants expressing varying levels of GL3 …

Introduction To N-Adaptive Fuzzy Models To Analyze Public Opinion On Aids, Florentin Smarandache, W.B. Vasantha Kandasamy

Branch Mathematics and Statistics Faculty and Staff Publications

“AIDS is not simply a physical malady, it is also an artifact of social and sexual transgression, violated taboo, fractured identity—political and personal projections. Its key words are primarily the property of the powerful. AIDS: Keywords – is my attempt to identify and contest some of the assumptions underlying our current ‘knowledge’. In this effort I am joined by many AIDS activists including people living with AIDS— Acquired Immuno Deficiency Syndrome. “A syndrome is a pattern of symptoms pointing to a “morbid state” which may or may not be caused by infectious agents; a disease, on the other hand is, …

Oral Cancer Prevalence In Virginia, Karin C. Loftin, Michele Darby, Stacey Plichta, Sophie Thompson, Shreeram Kumar, Louis Abbey

Dental Hygiene Faculty Publications

Purpose. Oral and pharyngeal cancer affects 30,000 Americans a year and kills one fourth of those diagnosed. The primary risk factors for oral cancer are past or present cigarette and tobacco usage, and alcohol consumption in conjunction with tobacco use. Even though the prevalence of oral cancer is relatively low in the younger age groups, this group is most likely to benefit from intervention programs designed to change risky behavior such as smoking, and to prevent oral cancer in the later years. The goal of the study was to identify high-risk target areas for an oral cancer prevention program in …

Distribution And Status Of The Southern Bog Lemming, Synaptomys Cooperi, In Southeastern Virginia, Robert K. Rose

Virginia Journal of Science

The Dismal Swamp subspecies of the Southern bog lemming, Synaptomys cooperi helaletes, was named based on specimens collected during the 1895-1898 biological surveys conducted in the Dismal Swamp by the US Department of Agriculture. Unknown in the 20th Century until re-discovered in 1980, this small boreal rodent was believed to be restricted to the Great Dismal Swamp of Virginia and North Carolina where the cool damp conditions had permitted it to survive during the Holocene. However, field studies conducted since 1980 have revealed southern bog lemmings to be widespread throughout southeastern Virginia, with populations encompassing an area of more …
