AAES Research Reports and Research Bulletins
A three year study at the Livestock and Forestry Research Station near Batesville, Arkansas evaluated production systems involving stocker cattle and soft red winter wheat. Grazing of soft red winter wheat forage from October through February followed by harvesting wheat grain or grazing through April with stocker cattle offers an alternative to conventional farming. Soft red winter wheat, when planted by September 15, produces an ample supply of high-quality forage that supports rapid growth of stocker cattle during October through April. Net income from stocker cattle averaged over $100 per acre. A normal wheat grain crop can also be harvested. …

Illinois River Phosphorus Sampling Results And Mass Balance Computation, Marc Nelson, K.L. White, T.S. Soerens
Illinois River Phosphorus Sampling Results And Mass Balance Computation, Marc Nelson, K.L. White, T.S. Soerens
Arkansas Water Resources Center Technical Reports
Phosphorus levels in the Illinois River are of great interest to the people of the States of Arkansas and Oklahoma. A great deal of effort has been expended to ascertain and modify the phosphorus impacts on the river. An automatic water sampling station was installed on the Illinois River just upstream from the State line in 1996 to accurately quantify the phosphorus in the Arkansas portion of the watershed. This paper summarizes five years worth of phosphorus sampling results at that site. In addition, a simple mass balance for phosphorus in the Illinois River Watershed above the sampling station was …
The Effects Of Enclosure Type On Aggressive Behavior In Captive Chimpanzees, Erica Renee Findley
The Effects Of Enclosure Type On Aggressive Behavior In Captive Chimpanzees, Erica Renee Findley
Inquiry: The University of Arkansas Undergraduate Research Journal
Male chimpanzees are known to be aggressively territorial in the wild. It is expected that the limited enclosures of captivity would make them even more aggressive. The Kansas City Zoo was chosen as an ideal venue to explore this assumption because it boasts the largest outdoor enclosure of its kind, and the apes alternate between this and much smaller indoor housing. Quantitative data on crowd size, time of day, temperature, and frequency/intensity/duration of aggressive behaviors were recorded for the alpha male in both enclosures during 300 hours of observation. These data were used to test the following hypotheses: as measured …
Glycogen Resynthesis And Recovery From Exercise: Effects Of Very-Long Chain Acyl-Coenzyme, A Dehydrogenase Deficiency, Kyle E. Johnson
Glycogen Resynthesis And Recovery From Exercise: Effects Of Very-Long Chain Acyl-Coenzyme, A Dehydrogenase Deficiency, Kyle E. Johnson
Inquiry: The University of Arkansas Undergraduate Research Journal
Disorders of fatty acid metabolism pose a variety of problems including hypoglycemia, muscle weakness, muscle cramping, rhabdomyolysis, and, in the most severe cases, death. Individuals with a deficiency of very-long-chain acyl-CoA dehydrogenase (VLCAD ), the enzyme initiating the oxidation of very-long-chain fatty acids, are particularly prone to exercised-induced declines in muscle function because oft he importance of very-long-chain fatty acids to energy metabolism in exercise. The purpose of this project was to study muscle glycogen resynthesis in the recovery from high intensity exercise in VLCAD deficient mice. Recovery of skeletal muscle function (gastrocnemius) following exercise is not as rapid in …
Actin Dynamics Regulate Myosin Assembly In Muscle Cells, John Dylan Cook
Actin Dynamics Regulate Myosin Assembly In Muscle Cells, John Dylan Cook
Inquiry: The University of Arkansas Undergraduate Research Journal
During muscle cell (i.e. myocyte )development, organization of actin and myosin into the contractile unit (i.e. sarcomere) is required for proper muscle contraction. By disrupting the processes of muscle cell development, I am able to see which steps play important roles in proper maturation of myocytes. Elucidation of the key pathways in muscle development could lead to a better understanding of human cardiac hypertrophies and muscle myopathies. Since actin filament formation precedes myosin organization, I am using actin assembly inhibitors to determine if actin filaments are a necessary prerequisite for myosin organization. It is hypothesized that disruption of actin will …

Native Plants: The Preservation And Restoration Of Native Plants In Designed Landscapes In Northwest Arkansas, Janet Coleman
Native Plants: The Preservation And Restoration Of Native Plants In Designed Landscapes In Northwest Arkansas, Janet Coleman
Inquiry: The University of Arkansas Undergraduate Research Journal
A decline in Northwest Arkansas's native plant population has occurred over the past 50 years, as documented by the U.S. Forest Service in the Ozark-Ouachita Highlands Assessment. This decline has been caused by increased human development in natural areas and the replacement of native plants with exotic, non-native plants. As a result, a generation has grown up not knowing what an Ozark wake Robin trillium (Trillium pusillum var. ozarkanum) or Blood root (Sanguinaria canadensis) Look like, because these plants are difficult to find in nature, are not commonly grown in designed landscapes, and are Largely unavailable in garden centers. The …
Characterization Of Wound-Inducible Genes Encoding Enzymes For Terpenoid Biosynthesis In Medicago Truncatula, Mandy M. Cox
Characterization Of Wound-Inducible Genes Encoding Enzymes For Terpenoid Biosynthesis In Medicago Truncatula, Mandy M. Cox
Inquiry: The University of Arkansas Undergraduate Research Journal
In addition to having numerous applications as food flavorings and pharmaceuticals, terpenoids are an important class of defensive compounds that can accumulate in plants after pathogen infection or injury by insects. Sequences of DNA encoding putative terpene synthases and an oxidosqualene synthase, isolated from insect-damaged Medicago truncatula leaves, were selected from an expressed sequence tag (EST) database. The eDNA clones were used as radiolabeled probes to analyze gene expression in leaves treated with factors known to trigger a defense response in plants. Transcript levels for all of the genes examined increased in response to artificial wounding, insect herbivory, and methyl …

Distributions And Geographical Relationships Of The Polygyrid Land Snails (Mollusca, Gastropoda, Polygyridae) Of Arkansas, Gerald E. Walsh, Brian F. Coles
Distributions And Geographical Relationships Of The Polygyrid Land Snails (Mollusca, Gastropoda, Polygyridae) Of Arkansas, Gerald E. Walsh, Brian F. Coles
Journal of the Arkansas Academy of Science
The Arkansas distributions of land mollusks of the family Polygyridae are presented based on the results of a state-wide survey and a critical review of published and unpublished locality records. Six of the 45 species previously recorded for Arkansas are excluded because they were misidentified, do not have established populations in the state, or are found only as fossils. Four others are not mapped because of a lack of recent distributional data or because the specific status of a form is unclear. There is a predominant pattern of occurrence limited to the northern, northwestern, or western parts of the state. …
Beetle Diversity In An Eastern Cottonwood (Populus Deltoides Bartr.) Plantation And Adjacent Bottomland Hardwood Forest In Southeastern Arkansas, Michael D. Warriner, T. Evan Nebeker, Steven A. Tucker
Beetle Diversity In An Eastern Cottonwood (Populus Deltoides Bartr.) Plantation And Adjacent Bottomland Hardwood Forest In Southeastern Arkansas, Michael D. Warriner, T. Evan Nebeker, Steven A. Tucker
Journal of the Arkansas Academy of Science
Within the Lower Mississippi Alluvial Valley (LMAV),some lands cleared of bottomland hardwood forests have the potential to return to forest as a result of private sector and government interests in Populus cultivation. Specifically, monoculture plantings of eastern cottonwood (Populus deltoides Bartr.) represent an important component of many recent afforestation efforts in the region. The impact establishment of such monocultures will have on native insect communities in the LMAV is relatively unknown. To evaluate this, beetle (Coleoptera) diversity, abundance, and functional distribution were examined within an intensively managed eastern cottonwood plantation and nearby bottomland hardwood forest in southeastern Arkansas. Beetles were …

Development Of A Yeast Biosensor Strain For The Identification Of Genotoxic Compounds, Robin M. Reed
Development Of A Yeast Biosensor Strain For The Identification Of Genotoxic Compounds, Robin M. Reed
Inquiry: The University of Arkansas Undergraduate Research Journal
Advances in combinatorial chemistry have provided the pharmaceutical industry with innumerable lead compounds that could potentially serve as therapeutic agents. One of the challenges in the further development of such compounds is to rapidly, yet inexpensively, distinguish those that have undesirable effects such as genotoxicity. Thus, a simple biological assay that would permit the identification of potential DNA mutagens, and be adaptable to high-throughput technologies would be cost effective in screening such lead compounds. The current methods use the Ames and SOS tests involving prokaryotic organisms, while systems that utilize mammalian cell culture and/or animal testing are time-consuming and expensive. …
A World Of Their Own: Woman And Folklore In Inter-War Britain, Natalie Holub
A World Of Their Own: Woman And Folklore In Inter-War Britain, Natalie Holub
Inquiry: The University of Arkansas Undergraduate Research Journal
The period between the First and Second World Wars was an unsettling time for women in Great Britain. After the First World War, the media, governmental acts, and everyday society urged women to return to the home. This was an especially difficult concept for women to accept after they had played a very public role during the war actively contributing to the war effort. My thesis explores three novels of interwar England that feature female characters seeking purpose in places outside of the traditional role of housewife. Ashe of Rings by Mary Butts, Harriet Hume by Rebecca West, and Lolly …

Quantification Of Land-Use Impact On Stream Water Quality, Scott Dennis, Indrajeet Chaubey, Brian Haggard
Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences
Accelerated eutrophication of Beaver Lake in northwest Arkansas is a major environmental concern. When developing watershed-management plans to protect lake water quality, it is important that linkages among land-use activities and water quality of tributary streams be quantified. This study assessed longitudinal base-flow and storm-flow water quality at War Eagle Creek and quantified linkages between stream water quality and land-use conditions within the War Eagle Creek sub-watershed of the Beaver Lake watershed. We collected six water samples: three from base-flow conditions and three from storm-flow conditions during Spring 2002. In general, concentrations of nitrate nitrogen (NO3-N), total N (TN), total …

Distribution Of Clinostomum Marginatum (Yellow Grub) Metacercaria In Smallmouth Bass Populations From Crooked Creek In North Central Arkansas, James J. Daly, Bruce Deyoung, Terryl L. Hostetler, Randal J. Keller
Journal of the Arkansas Academy of Science
Four hundred thirty-three smallmouth bass (Micropterus dolomieui) were collected from ten sites on Crooked Creek in North Central Arkansas from just below the city of Harrison to the White River in the summers of 1988-90. Necropsy of these hosts for yellow grub (Clinostomum marginatum) metacercariae showed a range of mean abundance (average/fish) from 1.4 ±1.9 (SD) at a far up stream site to 105 ± 368 at the White River juncture. An increasing mean abundance of C. marginatum was seen from the uppermost sites of the creek downstream to the White River. Relating stream mileage with mean abundance gave a …
Modeling Of Electrofusion Coils For Performance Optimization, Steve Farmer, Robert A. Sims
Modeling Of Electrofusion Coils For Performance Optimization, Steve Farmer, Robert A. Sims
Journal of the Arkansas Academy of Science
Modeling physical parameters provides a virtual design environment allowing the confirmation and optimization of electrofusion characteristics. Finite element incorporate physical parameters and their interactions along common boundaries defined within a model geometry. The electrofusion of polymeric piping is a widely accepted means of assembling piping systems with zero-leakage integrity. The key parameters in the fusion process are the coil resistance, the current passing through the coil and the time the current is applied. Modeling the coil and applying current to the model is accomplished using the MATLABpartial differential equations (PDE) toolbox. This paper presents the method of modeling and the …
