Characterization Of Soluble Matrix From Molluscan Shell With An Emphasis On Two Major Phosphoproteins From The Eastern Oyster, Crassostrea Virginica, Mary Johnstone
All Dissertations
The soluble organic matrix (SM) extracted from the shell of the Eastern oyster, Crassostrea virginica was analyzed to identify the constituent proteins and their structures. Two acidic proteins with estimated molecular weights of 48 and 55 kD were isolated and determined to have highly related structures. Both proteins are comprised primarily of aspartate, serine, and glycine which represent nearly 90% of the total amino acids. Studies indicate that both proteins are phosphorylated and have estimated isoelectric points in the range of 3 to 5. Evidence suggests that poly-aspartate and poly-serine domains are present in the 48 kD protein. Amino terminal …
Investigating Risks, Effects, And A Potential Management Strategy For Avian Vacuolar Myelinopathy On Southeastern Reservoirs Using An Eco-Epidemiological Approach, Rebecca Haynie
All Dissertations
Avian vacuolar myelinopathy (AVM) is a neurologic disease of unknown etiology that has severely impacted waterbirds and raptors in the Southern United States since it was first diagnosed in 1994. Research studies have suggested that the causative agent is a neurotoxin produced by a previously undescribed Stigonematalan cyanobacterium which grows epiphytically on submerged aquatic vegetation. A suite of experiments were conducted to determine if: (1) triploid Chinese grass carp (Ctenopharyngodon idella) are an appropriate management strategy for AVM; (2) to measure mammalian susceptibility to cyanobacterium exposure; and, (3) to discern population-level impacts to American coots (Fulica americana) and bald eagles …

Biodiesel Production From High Free Fatty Acid Content Feedstocks, Kaewta Suwannakarn
All Dissertations
Biomass, such as animal fats and grease, is one of the better sources for transportation fuels, e.g. biodiesel. Use of such biomass in the biodiesel synthesis decreases the need for fossil energy, provides an outlet for utilizing the abundant resources effectively and economically, results in a cleaner fuel that is biodegradable, renewable, and non-toxic. Free fatty acid (FFA) esterification and triglyceride (TG) transesterification with low molecular weight alcohols are the central reactions for the biodiesel production. The focus of this research is to establish a better fundamental insight into heterogeneous catalysis for biodiesel forming reactions, in an attempt to design …
Population Dynamics Of The Cotton Aphid, Aphis Gossypii Glover (Homoptera: Aphididae), And Its Fungal Pathogen, Neozygites Fresenii (Nowakoski) Batko (Entomopthorales: Neozygitaceae) In South Carolina, Ruly Anwar
All Dissertations
The broad spectrum insecticide, acephate, neonicotinoid insecticides, acetamiprid, thiamethoxam, and imidacloprid, and other insecticides, λ-cyhalothrin, emamectin benzoate, indoxacarb, and spinosad were evaluated for their effects on the cotton aphid, Aphis gossypii, its entmopathogenic fungus, Neozygites fresenii, aphid parasitoids, lacewings, and coccinellids. Numbers of cotton aphids were significantly higher in plots treated with broad-spectrum insecticide than in untreated plots. Also, levels of both fungus-infected aphids and parasitized aphids were significantly higher in plots treated with broad-spectrum insecticide than in untreated plots. Numbers of lacewings and coccinellids were not significantly different between insecticide treated and untreated plots. Levels of fungus-infected aphids were …
Development Of A Novel Fouling Deterrence Strategy By Understanding The Efect Of Noradrenaline On The Cells Of Eastern Oyster, Crassostrea Virginica And Cypris Larve Of The Striped Barnacle Balanus Amphitrite, Neeraj Gohad
All Dissertations
ABSTRACT
The focus of this study was to understand and evaluate the effect of noradrenaline (NA) on two prominent fouling marine invertebrates, the Eastern Oyster, Crassostrea virginica and the Striped Barnacle, Balanus amphitrite for the purpose of developing a novel fouling deterrence strategy.
To understand the effect of NA at a cellular level the immune cells (hemocytes) of C. virginica were chosen as representative molluscan cells. Upon stimulation with 10 micro-molar of noradrenaline ~4% hemocytes of C. virginica labeled positive for the beta-adrenergic receptor (beta-AR). Upon NA stimulation the beta-AR positive cells formed cell-cell synapses and apoptosis was detected in …
Insight Into The Origins Of The Rumex Acetosa Sex Chromosomes And Mechanisms Causing Dimorphism, Samuel Forrest
Insight Into The Origins Of The Rumex Acetosa Sex Chromosomes And Mechanisms Causing Dimorphism, Samuel Forrest
All Dissertations
Sex conferring chromosomes are subject to rapid change throughout evolution. Y-chromosomes (male determining) are subject to extensive chromatin remodeling and higher mutation rates than the autosomes being that recombination with the X chromosome is inhibited in many regions. The non-recombining regions comprise varying proportions of Y chromosomes from species to species and they are subject to mutation acquisition including both deletions and insertions. Recently it has been shown that these insertion mutations include repetitive DNA such as satellite DNA sequences (satDNA) and transposable elements. It is thought that Y chromosomes go through many rounds of expansion and contraction throughout evolution …

Journal of Youth Development
Informal educational programs that reach out to minority youth in low-income urban areas need to anticipate diversity. Not only will participants exhibit a range of abilities and needs, but some, just like in any population, are likely to have learning disabilities. ScienceQuest, an informal science education program funded by the National Science Foundation, was designed to ensure that youth aged 10 to 14 with diverse abilities and needs, including learning disabilities, can successfully participate and succeed in inquiry-based learning. The program uses the I-Search curriculum as the basis of its inquiry process. Embedded in this curriculum are the following inclusive …

In this paper, the design of a simulation model for evaluating two alternative supercomputer configurations in an academic environment is presented. The workload is analyzed and modeled, and its effect on the relative performance of both systems is studied. The Integrated Capacity Planning Environment (ICPE) toolkit, developed for commodity cluster capacity planning, is successfully applied to the target environment. The ICPE is a tool for workload modeling, simulation modeling, and what-if analysis. A new characterization strategy is applied to the workload to more accurately model commodity cluster work- loads. Through "what-if" analysis, the sensitivity of the baseline system performance to …

Once introduced, diseases may spread quickly through new areas, infecting naive host populations, such as has been documented in Ebola virus in African primates or rabies in North American mammals. What drives the spread of the pathogenic fungus Batrachochytrium dendrobatidis (Bd), which causes chytridiomycosis, is of particular concern because it has contributed to the global
decline of amphibians. We modeled the spatiotemporal pattern of the loss of upland amphibian populations in Central and South America as a proxy for the arrival of Bd and found that amphibian declines in Central and South America are best explained by Bd spreading through …

The Public Domain: Enclosing The Commons Of The Mind, James Boyle
The Public Domain: Enclosing The Commons Of The Mind, James Boyle
A repository of copyright educational resources for higher education
Used in many intro to copyright law classes, this enlightening book describes what author James Boyle “calls the range wars of the information age today’s heated battles over intellectual property. Boyle argues that just as every informed citizen needs to know at least something about the environment or civil rights, every citizen should also understand intellectual property law. Why? Because intellectual property rights mark out the ground rules of the information society, and today’s policies are unbalanced, unsupported by evidence, and often detrimental to cultural access, free speech, digital creativity, and scientific innovation.”
Mechanics Of Limb Bone Loading During Terrestrial Locomotion In River Cooter Turtles (Pseudemys Concinna), M. T. Butcher, R. W. Blob
Mechanics Of Limb Bone Loading During Terrestrial Locomotion In River Cooter Turtles (Pseudemys Concinna), M. T. Butcher, R. W. Blob
Publications
Studies of limb bone loading during terrestrial locomotion have focused primarily on birds and mammals. However, data from a broader functional and phylogenetic range of species are critical for understanding the evolution of limb bone function and design. Turtles are an interesting lineage in this context. Although their slow walking speeds and robust limb bones might lead to low locomotor forces and limb bone stresses similar to other non-avian reptiles, their highly sprawled posture could produce high bending loads, leading to high limb bone stresses similar to those of avian and mammalian species, as well as high torsion. To test …

Sulawesi Island has a high density of endemic animal species, including insects in the order Trichoptera. We describe the males of four new species of Cheumatopsyche (Trichoptera: Hydropsychidae) from North Sulawesi (Provinsi Sulawesi Utara), and provide a checklist of the Cheumatopsyche species from the Indonesian archipelago. Describing the aquatic insect fauna is an important step toward establishing biomonitoring protocols in Indonesia, which is experiencing rapid development and water pollution problems.

Engine Performance Test Of Cottonseed Oil Biodiesel, Xiaohu Fan, Xi Wang, Feng Chen, Daniel P. Geller, Peter J. Wan
Publications
Two cottonseed oil biodiesel samples (cottonseed oil methyl esters, COME) produced in Clemson lab, together with other two commercial cottonseed oil biodiesels were evaluated on their engine performance with the No. 2 diesel fuel as a reference. The results revealed that emission of CO, CO2 and NOx from cottonseed oil biodiesels was lower than that of the No. 2 diesel fuel. CO decreased by 13.8%, CO2 by 11.1% and NOx by 10%, though there was no significantly statistical difference at p<0.05. The engine test also showed a slightly higher amount of consumption and less tendency of coke formation from COME than the No. 2 diesel fuel. The oxidative stability study showed COME with acceptable stability. COME exhibited friendly environmental benefits and acceptable stability, demonstrating its feasibility as an alternative fuel.

Publications
Previous analyses of ground reaction force (GRF) and kinematic data from river cooter turtles (Pseudemys concinna) during terrestrial walking led to three primary conclusions about the mechanics of limb bone loading in this lineage: (1) the femur was loaded in a combination of axial compression, bending and torsion, similar to previously studied non-avian reptiles, (2) femoral shear stresses were high despite the possession of a reduced tail in turtles that does not drag on the ground and (3) stress-based calculations of femoral safety factors indicated high values in bending and torsion, similar to other reptiles and suggesting that substantial `overbuilding' …
