Characterizing The Variability Of Physical And Chemical Properties Across The Soil Individuals Mapped As Amy Silt Loam Soils In Southeastern Arkansas, B. Bhandari, Robert L. Ficklin Jan 2009

Characterizing The Variability Of Physical And Chemical Properties Across The Soil Individuals Mapped As Amy Silt Loam Soils In Southeastern Arkansas, B. Bhandari, Robert L. Ficklin

Journal of the Arkansas Academy of Science

Knowledge of physical and chemical properties of soil is relevant for landowners, researchers, and foresters, so that appropriate crop species and management practices to maximize site productivity can be selected. In addition to issues of plant productivity, the need for assessing soil properties has been expanded due to public interest in determining the consequences of management practices on soil quality relative to sustainability of crop ecosystem functions. The USDA-Natural Resources Conservation Service (NRCS) delineated soil mapping units to provide information about physical and chemical properties of soil in each soil series. However, soil mapping units do not provide details about …

Biological And Economic Considerations In Establishing A Short-Rotation Bioenergy Plantation, Jamie L. Schuler, M. Pelkki, Chris Stuhlinger Jan 2009

Biological And Economic Considerations In Establishing A Short-Rotation Bioenergy Plantation, Jamie L. Schuler, M. Pelkki, Chris Stuhlinger

Journal of the Arkansas Academy of Science

The development of bio-fuel synthesis technologies has led to increased interest in woody crops grown specifically for energy production. These woody feedstocks typically involve fast-growing species (e.g., Salix spp., Populus spp.) planted at high densities using short rotations and intensive cultural practices like weed control and fertilization. Under ideal conditions, this type of system can produce 20 dry Mg/ha/yr, which is substantially higher than the 2.5-4 dry Mg/ha/yr produced by pine plantations in the southern U.S. Many of these plantings are projected to be established on lower quality agricultural lands. Recent attempts at establishing these plantations have highlighted some of …

Nutritional Immunomodulation As An Approach To Decreasing The Negative Effects Of Stress In Poultry Production, G. R. Huff, W. E. Huff, N. C. Rath Jan 2009

Nutritional Immunomodulation As An Approach To Decreasing The Negative Effects Of Stress In Poultry Production, G. R. Huff, W. E. Huff, N. C. Rath

Journal of the Arkansas Academy of Science

Stress can lead to changes in the immune response resulting in both increased and decreased resistance to opportunistic bacterial pathogens. Growth-promoting antibiotics have been a major tool in modulating hostpathogen interactions and limiting clinical and subclinical bacterial infection in confined animal production. Regulatory pressures to limit antibiotic use in poultry production and recent international marketing agreements that prohibit treating poultry with antibiotics have limited the disease-fighting tools available to poultry and livestock producers, particularly in Europe. There is a need to evaluate potential antibiotic alternatives to improve both production and disease resistance in high-intensity food animal production. Nutritional approaches to …

Distribution And Population Characteristics Of Lower Walleye In The Eleven Point River, Arkansas, Ronald L. Johnson, S. D. Henry, Sam W. Barkley

Journal of the Arkansas Academy of Science

Walleye Sander vitreus (Mitchill) distributions and ecology have been poorly studied in southern river basins. We studied the longitudinal distribution and population characteristics of walleye in an unregulated river within the Ozark region of the U.S., the lower Eleven Point River, Arkansas, which has high species diversity. Walleye were collected in a 60 km segment of the river by daytime boat electrofishing over a three year period (2002-2004). Catch rates, growth rates and size structure were high relative to other streams studied in North America. Catch per effort ( = 5.2/h) was similar seasonally, spatially and among years. Proportional stock …

S. Barnett, H. C. Martin, J. H. Seagraves, M. W. Matthews, R. Winterringer, C. Osborne, Alan D. Christian, N. J. Wentz

Journal of the Arkansas Academy of Science

We analyzed stream inventories, phylogeographic studies, community and population estimates, life history and reproductive biology research, and suitable habitat investigations conducted from 1997-2008, as well as the Arkansas Natural Heritage Commission mussel database, to update the conservation status for all native freshwater unionoid bivalves thought to occur in Arkansas. Prior to this study, Harris et al. (1997) reviewed the distribution and status of 75 freshwater mussels considered native to Arkansas and ranked 22 species as endangered, threatened or special concern. We now recognize 85 mussel taxa in Arkansas; however, some of those have yet to be described or their nomenclature …

Microwave Dielectroscopy Of Breast Tissue Phantoms In The 5.8-40 Ghz Range, Binh Tran

Electrical Engineering Undergraduate Honors Theses

Based on the high contrast in dielectric properties between the low-water-contain sample and the high-water-content one, we can determine whether the tissue sample is cancerous or normal. In order to make the measurement repeatable and convenient, some phantom materials, which have the same dielectric properties of human tissues, have been prepared. These phantom tissues are made from gelatin, water with honey syrup and Sodium Chloride (NaCl). In this project, we are going to measure and compare the dielectric properties of different types of phantom tissues by using focused beam antennas. The purpose of this project is to perform a systematic …
