Development Of Gis-Based Chemical Distribution Maps From Sprayer Performance Data, Joe D. Luck, Santosh Pitla, Rodrigo S. Zandonadi, Scott A. Shearer

Department of Animal Science: Faculty Publications

Pesticide application is an essential practice on farms in Kentucky where glyphosate resistant crops and no-till farming strategies are becoming more popular. Off-rate pesticide application errors are the result of incorrect concentrations applied to an area of the field and may result from velocity changes along the spray boom while the sprayer is turning, pressure changes across the width of the spray boom, and changes in effective boom height due to undulating terrain. In an attempt to estimate potential errors resulting from sprayer turning movements, a method was developed to compare the differences in application areas between control sections across …

Evaluation Of A Terrain Attribute Model For Locating Areas Suitable For Grassed Waterways In Agricultural Settings, Joe D. Luck, Adam C. Pike, Santosh Pitla, Tom Mueller, Scott A. Shearer

Department of Animal Science: Faculty Publications

Grassed waterways placed in high water flow zones substantially reduce erosion in agricultural fields. A recent study proposed a statistical model for waterway planning for a farm in the Outer Bluegrass physiographic region of Kentucky. The logistic regression model identified where channel erosion was likely to occur based on elevation-derived terrain attributes. The objective of this study was to test their model in fields located in the Western Coal Fields physiographic region where soils differ substantially. Model predictions corresponded well with known areas of concentrated flow (i.e., maps of existing waterways, surface drains, and observations of erosion). The geographic inference …

Background: Identification and culling of replacement gilts with poor skeletal conformation and feet and leg (FL) unsoundness is an approach used to reduce sow culling and mortality rates in breeding stock. Few candidate genes related to soundness traits have been identified in the pig.

Methods: In this study, 2066 commercial females were scored for 17 traits describing body conformation and FL structure, and were used for association analyses. Genotyping of 121 SNPs derived from 95 genes was implemented using Sequenom's MassARRAY system.

Results: Based on the association results from single trait and principal components using mixed linear …

Age And Diet Affect Gene Expression Profile In Canine Skeletal Muscle, Ingmar S. Middelbos, Brittany M. Vester, Lisa K. Karr-Lilienthal, Lawrence B. Schook, Kelly S. Swanson

Department of Animal Science: Faculty Publications

We evaluated gene transcription in canine skeletal muscle (biceps femoris) using microarray analysis to identify effects of age and diet on gene expression. Twelve female beagles were used (six 1-year olds and six 12-year olds) and they were fed one of two experimental diets for 12 months. One diet contained primarily plant-based protein sources (PPB), whereas the second diet contained primarily animal-based protein sources (APB). Affymetrix GeneChip Canine Genome Arrays were used to hybridize extracted RNA. Age had the greatest effect on gene transcription (262 differentially expressed genes), whereas the effect of diet was relatively small (22 differentially expressed genes). …

Association And Haplotype Analyses Of Positional Candidate Genes In Five Genomic Regions Linked To Scrotal Hernia In Commercial Pig Lines, Zhi-Qiang Du, Xia Zhao, Natascha Vukasinovic, Fernanda Rodriguez, Archie C. Clutter, Max F. Rothschild

Department of Animal Science: Faculty Publications

Scrotal hernia in pigs is a complex trait likely affected by genetic and environmental factors. A large-scale association analysis of positional and functional candidate genes was conducted in four previously identified genomic regions linked to hernia susceptibility on Sus scrofa chromosomes 2 and 12, as well as the fifth region around 67 cM on chromosome 2, respectively. In total, 151 out of 416 SNPs discovered were genotyped successfully. Using a family-based analysis we found that four regions surrounding ELF5, KIF18A, COL23A1 on chromosome 2, and NPTX1 on chromosome 12, respectively, may contain the genetic variants important for the …

Effect Of Hydrogen Peroxide In The Scald Tank On The Microbial Count Of Pork Skin, A. S. De Mello Jr., R. O. Roca

Department of Animal Science: Faculty Publications

The objective of this study was to investigate the effect of hydrogen peroxide (H₂O₂) (50% v/v) on pork skin microbial populations. Forty-eight crossbred hogs were analyzed after dehairing and 30 during chilling. Three different concentrations of hydrogen peroxide were added to the scalding water (0.01, 0.05 and 0.1% of the total capacity of the scald tank). In treatment I no addition of H₂O₂ was applied while, in treatment II, H₂O₂ was added at 0 min and, in treatment III, it was added at 0, 30 and 60 min. Both treatments …

Preventive Health Engineering In Earlier And Later Life, Johanna E.M.H. Bronswijk, William D. Kearns

Rehabilitation and Mental Health Counseling Faculty Publications

Preserving autonomy and independence up to the highest ages calls for a major reduction in chronic conditions. By applying the Compressing Morbidity concept that concentrates the period of senescence near the end of life, the number of healthy years can be enlarged. Many chronic conditions are elicited by lifetime exposures to environmental factors, such as (indoor) air pollution (asthma, COPD, lung cancer), noise exposure (hearing disorders), or physically unbalanced work or sports (mobility disorders), to name a few. Unfortunately, in earlier life there is little interest in expected later health. Persuasive technology is useful here. Since, in the Western World, …

Defining Gerontechnology For R&D Purposes, Johanna E.M.H. Bronswijk, Herman Bouma, James L. Fozard, William D. Kearns, Gerald C. Davison, Pan-Chio Tuan

Rehabilitation and Mental Health Counseling Faculty Publications

Gerontechnology is an interdisciplinary field that links existing and developing technologies to the aspirations and needs of aging and aged adults. It helps support ‘successful aging’, is organized according to the WHO definition of health, and is a response to the combination of the aging of society and rapidly emerging new technologies. Distinguishing it from other technology approaches is its focus on the total human life-span, its recognition of different technology generations, its cross-fertilization of specific technology and gerontology disciplines, its public health goals and the encompassing of all domains of human activity. An enhanced quality of life in older …

The Biochemical Reactions Of Dry State Dna, April Marrone

Electronic Theses and Dissertations

The biochemistry of dry state DNA is of interest to the fields of forensics, ancient DNA, and DNA storage. The exact chemical nature of the degradation of the DNA molecule in the dry state has not been studied prior. If determined what chemical changes the DNA molecule undergoes, to what degree and in what time frame then protocols can be implemented to bypass the impact of this damage or to repair it when necessary. It is suspected that similar reactions occur to the dry state DNA molecule as does to the hydrated molecule. It cannot be assumed, however that these …

Water And The Mountains: Maya Water Mangement At Caracol, Belize, James Crandall

Electronic Theses and Dissertations

Water management techniques in the Southern Maya Lowlands are both regionally diverse and site specific. This thesis examines the water management strategies of the Classic Period Maya at the site of Caracol, Belize. While it is likely that elites at Caracol controlled the redistribution of resources, i.e. craft and agricultural products, it is probable that the production of agricultural resources and the maintenance of water resource acquisition took place on a more local level. In order to test this hypothesis, a sample of five reservoirs were examined through original research -- and situated in conjunction with past settlement studies -- …

A Biocultural Analysis Of Nubian Fetal Pot Burials From Askut, Sudan, Lauren Britton

Electronic Theses and Dissertations

The skeletal remains in this study were excavated from the Nubian archaeological island fortress site of Askut (ca. 1850 BC - 1070 BC, New Kingdom/Third Intermediate period), located at the 2nd Cataract of the Nile river in Sudan. These remains were recovered as part of an archaeological expedition from 1962-1964, which was an effort to learn as much as possible about this site before the building of the High Dam in Aswan. Seven fetal skeletons (dated ca. 1260-770 BC) were examined for their biocultural significance. Biological analysis of these individuals indicates a range in developmental age from 36 to 40 …

Habitat Use By The Southeastern Beach Mouse (Peromyscus Polionotus Niveiventris) At Cape Canaveral Air Force Station, Florida, Kathryn Simmons

Electronic Theses and Dissertations

Successful recovery of the federally threatened southeastern beach mouse (Peromyscus polionotus niveiventris) depends in part on an understanding of their habitat requirements. I studied habitat use by beach mice at Cape Canaveral Air Force Station, Florida from March 2005 until March 2006. I livetrapped six grids, three on coastal dunes and three within scrub located inland from the coast. On each grid and trap station, I quantified the extent of bare ground, woody vegetation, non-woody vegetation, height of vegetation, and percentage of coarse sand in the surface soil. I assessed trap success relative to these habitat variables using linear and …

Application Of Alkylsilane Self-Assembled Monolayers For Cell Patterning And Development Of Biolocial Microelectromechanical Systems, Kerry Wilson

Electronic Theses and Dissertations

Advances in microfabrication and surface chemistry techniques have provided a new paradigm for the creation of in vitro systems for studying problems in biology and medicine in ways that were previously not practical. The ability to create devices with micro- to nano-scale dimensions provides the opportunity to non-invasively interrogate and monitor biological cells and tissue in large arrays and in a high-throughput manner. These systems hold the potential to, in time, revolutionize the way problems in biology and medicine are studied in the form of point-of-care devices, lab-on-chip devices, and biological microelectromechanical systems (BioMEMS). With new in vitro models, it …

Condition Relative To Phenotype For Bass Populations In Southern Arkansas Lakes, R. Allen, C. Cato, Colton Dennis, Ronald L. Johnson

Journal of the Arkansas Academy of Science

Southern Arkansas reservoir largemouth bass populations (Micropterus salmoides) are often supplemented with stocks of Florida bass (M. floridanus) in an attempt to boost the frequency of hybrid and trophy bass. Stocking rates of Florida bass among these lakes are highly variable. We determined bass phenotype composition among 12 lake populations based upon stocking protocols: exclusively Florida bass, primarily Florida bass, mixed stocking protocol and primarily largemouth bass. We also compared condition among phenotypes (n =2,100) to test for hybrid or phenotype vigor. Mean relative weight of bass for most lakes but SWEPCO Lake (mean Wr = 72) were ≥ 90. …

Temporal Changes Of Largemouth Bass Alleles In A Northern Arkansas Reservoir Stocked With Florida Bass, R. Allen, Ronald L. Johnson

Journal of the Arkansas Academy of Science

Southwest Electric Power Company (SWEPCO) Lake in northwest Arkansas is a thermal cooling pond for the Flint Creek Power Station. This reservoir has been regularly stocked with Florida bass (Micropterus floridanus) on top of a pre-existent largemouth bass (M. salmoides) population since its creation in 1976. Allozyme analysis of diagnostic loci in 1995-1996 revealed that 62% of the alleles were Florida bass alleles and that most fish were FX hybrids (77%). Microsatellite analysis of diagnostic loci in 2006 revealed that 78% of the alleles were Florida bass alleles and that most fish were FX-Florida hybrid bass (59%), with the remainder …

Qualitative Freshwater Mussel Survey Of The South Fork Spring River, Missouri And Arkansas, H. C. Martin, John L. Harris, Alan D. Christian

Journal of the Arkansas Academy of Science

A qualitative freshwater mussel survey was performed in the South Fork Spring River, Arkansas between May 13 and June 20, 2006 to assess community composition, density, and the presence of endangered mussel species (Family Unionidae). Twenty-one species from 460 individuals of mussels were collected using qualitative methods. Of those 21 species, 11 were ranked as S1, S2, or S3 using rankings established by the Arkansas Natural Heritage Commission Heritage Program. Three species, Amblema plicata (Say 1817), Lampsilis reeveiana (Call 1887), and Ptychobranchus occidentalis (Conrad 1836), comprised 48% of all mussels collected with 12%, 15%, and 21%, respectively. Mussel abundance within …

Species Richness, Distribution, And Relative Abundance Of Freshwater Mussels (Bivalvia: Unionidae) Of The Buffalo National River, Arkansas, M. Matthews, F. Usrey, S. W. Hodges, John L. Harris, Alan D. Christian

Journal of the Arkansas Academy of Science

The Buffalo River in north-central Arkansas is approximately 246 km long and flows through the Boston Mountains and Springfield and Salem Plateaus to the White River near Buffalo City. The Buffalo River is America’s first National River with the National Park Service owning 11% of land in the watershed. The objectives of this project were to survey the entire perennially wet length of river, search for mussels of conservation concern, and document the freshwater mussel assemblages. During 2004 and 2005, 235 km of the river were qualitatively and quantitatively surveyed. We documented 64 mussel assemblages. Time constrained qualitatively sampled assemblages …

Determination Of Benthic Soil Conditions Using Nematodes: Nematode Foodweb Conditions Of Fish Ponds In The Lincoln And Desha Counties Of Arkansas, M. M. Matute, P. W. Perschbacher, A. Newell

Journal of the Arkansas Academy of Science

We determined the health status of similar channel catfish (Ictalurus punctatus) ponds in Lincoln and Desha counties of Arkansas, using the nematode soil food web condition as our reference point. Soil nematodes were categorized into colonizer-persister (cp) groups, based on their life course characteristics e.g sensitivity to environmental changes, body size, etc. These cp groups represent different components of the soil food web, which in turn were indicators of soil conditions. Benthic soil samples were collected at four week intervals over a 4-month period, from 6-ponds in each county. The nematodes were extracted according to standard methods and the recovered …

Dna Sequence Analysis Of Freshwater Eustigmatophyceae, A Potential Source Of Essential Fatty Acids, Sara E. Prior, M. W. Fawley, K. P. Fawley

Journal of the Arkansas Academy of Science

Freshwater Eustigmatophyceae are a group of microalgae that are considered rare and of low diversity, with only a few genera and species in a single order. Some Eustigmatophyceae produce fatty acids that are important nutrients for aquaculture, as well as for human food consumption. In addition, some Eustigmatophyceae produce hydrocarbons that may be useful in biofuel production. In our studies of the diversity of coccoid algae from Itasca State Park, Minnesota, we discovered several isolates that we tentatively identified as Eustigmatophyceae. Preliminary molecular characterization indicated that these isolates were highly diverse and probably represented species new to science. In this …
