Feasibility Of Inducing Overlap Immunologic Competence In Gallinaceous Birds With Ascardia Dissimilis And A. Galli, Julie Hamilton, Thomas A. Yazwinski

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Chickens and turkeys are routinely infected with the roundworms Ascaridia galli and A. dissimilis, respectively. The current study was conducted to gather basic information on these worms and to determine whether heterologous infections (chicken worms in turkeys and turkey worms in chickens) would be successful. Chickens and turkeys were obtained at day of hatch, brooded to 7 days of age, and placed in pens (25/pen) according to infection as received at 7 days of age: homologous, heterologous and control (no infection). Bird weights, mortalities, and feed efficiencies were monitored for 3 weeks postinfection, at which time all birds were killed …

Livability Of Leghorn Balut Embryos Stored Under Varying Temperatures And Storage Times, Joyce Jong, F. Dustan Clark

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Baluts are fertile chicken or duck eggs that have been incubated and removed from the incubator prior to hatching for consumption. Chicken eggs are incubated for 11 to 14 days and duck eggs are incubated for 16 to 20 days. Baluts have an extremely specialized consumer market, with the majority of its consumers of Filipino decent. Current U.S. Department of Agriculture regulations for the storage of baluts prior to sale is 7.2ºC, the same as for infertile commercial table eggs. Consumer preference is to purchase live baluts for consumption. Since exposure to 7.2ºC causes embryo mortality within 8 hours of …

Fissure Characterization Of Rice Kernels Using Video Microscopy, Jerry W. Fendley, Terry J. Siebenmorgen, Rustico C. Bautista

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Fissures are fractures of a rice kernel that can be created during the drying and tempering process. They cause tremendous postharvest losses in milling yield. Understanding why and how rice kernels fissure will lead to optimal drying and tempering operations. This information could also provide input to plant breeders for producing rice cultivars that are more resistant to fissuring. Rice kernels were dried using various air conditions in a controlled environment chamber. The kernels were viewed by video microscopy to observe the occurrence of fissures. A videocassette recorder recorded the images for a 24-hour period after the drying process. The …

Prediction Of Rice Sensory Texture Attributes Using Spectral Stress Strain Analysis And Jack-Knife Model Optimization, Marura Lenjo, Jean-Francois Meullenet

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Sensory texture characteristics of cooked rice were predicted using an extrusion test and a novel multivariate analysis method. Eleven sensory texture characteristics were evaluated via a trained descriptive panel and predicted for force/deformation spectra with partial least squares regression. Only four sensory attributes—adhesion to lips (Rcal = 0.83), cohesion of bolus (Rcal = 0.78), cohesiveness (Rcal = 0.69), and hardness (Rcal = 0.72)—were successfully predicted from instrumental measurements.

Scientific Investigation Of The Plant Pathogen Agrobacterium Tumefaciens, Casey M. Flanagan, Christopher B. Crowell Ii, Bryan P. Markelz

Honors Theses

A. tumefaciensis a plant pathogen and causative agent of Crown Gall Disease, an ailment that results in the development of tumors in plants. It is a unique organism in that it is the only known non-viral pathogen that transfers its DNA into the host cell. Consequently, the majority of the research conducted on A. tumefaciensinvestigates its mechanism of infection. However, A. tumefaciensis also rare to the bacterial world in that its genome is comprised of two chromosomes: one circular and one linear. Most other bacteria only have one circular chromosome. This area of research has been grossly overlooked and therefore …

Characterizing The Role Of Mapk Phosphates In Plants, Laura Asakura

Honors Theses

Mitogen Activated Protein Kinase (MAPK) pathways e ubiquitous ongst eukaryotes, involved in the signal transduction of various external stimuli to the nucleus. In plants, only MAPK pathways related to pathogen- and stress-related responses have been identified. It has been proposed that another MAPK pathway exists in plants, one that is similar to animal MAPK pathways and postulated to connect the regulation of cell growth and the actions of hormones auxin, cytokinin, and gibberellin. In order to establish whether a link exists between the MAPK pathway and hormone signaling in plants, the role of MAPK phosphatases (MKP) on hormone signaling was …

Can An Optical Plankton Counter Produce Reasonable Estimates Of Zooplankton Abundance And Biovolume In Water With High Detritus?, X. Zhang, M. Roman, A. Sanford, H. Adolf, C. Lascara, R. Burgett

CCPO Publications

The Optical Plankton Counter (OPC) has been used in oceanic and fresh waters to estimate zooplankton abundance and biovolume. However, it is not clear whether the OPC can produce accurate estimates of zooplankton abundance and biovolume in waters with high detritus. In order to test the capability of the OPC to estimate zooplankton abundance and biovolume in Chesapeake Bay, two sets of laboratory experiments were conducted using water with high detritus concentrations collected from the upper Choptank estuary of Chesapeake Bay and laboratory cultured Artemia. Our results suggest that the OPC is able to produce accurate estimates of zooplankton biovolume …

The Linkage Between Upper Circumpolar Deep Water (Ucdw) And Phytoplankton Assemblages On The West Antarctic Peninsula Continental Shelf, Barbara B. Prézelin, Eileen E. Hofmann, Claudia Mengelt, John M. Klinck

OES Faculty Publications

Intrusion of Upper Circumpolar Deep Water (UCDW), which was derived from the Antarctic Circumpolar Current (ACC), onto the western Antarctic Peninsula (WAP) shelf region in January 1993 provided a reservoir of nutrient-rich, warmer water below 150 m that subsequently upwelled into the upper water column. Four sites, at which topographically-induced upwelling of UCDW occurred, were identified in a 50 km by 400 km band along the outer WAP continental shelf. One additional site at which wind-driven upwelling occurred was also identified. Diatom-dominated phytoplankton assemblages were always associated with a topographically-induced upwelling site. Such phytoplankton communities were not detected at any …

Theses: Doctorates and Masters

This study documented the macroalgal assemblages of the Swan-Canning Estuarine System (SCES) over a two year period, and the influences of several environmental parameters on the assemblages. In addition, the Impacts of unattached macroalgal accumulations on benthic nutrient fluxes and microbial communities were investigated. Benthic macroalgal assemblages and physico-chemical regimes were monitored in the SCES, to determine temporal and spatial changes in macroalgal communities and the influence of environmental factors in these changes. Physico-chemical regimes demonstrated strong seasonal changes, which revolved around the onset and cessation of freshwater flows in winter (May to September). In the months after freshwater flows, …

Analysis Of The Population Genetics Of The Han And Hui Of Liaoning Province, Peoples Republic Of China, Michael L. Black

Theses: Doctorates and Masters

Throughout recorded Chinese history, regions of the country populated by persons of non-Han ancestry often fluctuated significantly in population numbers and in their political and commercial influence. However, at all times they were considered as important contributors to the nation. Many of these peoples had moved from their homelands, settled in China and had intermarried with Han Chinese. Over the generations they became accepted as fully-fledged Chinese citizens although, in many instances, they retained their traditional customs and religious practices, and frequently their own language. The Hui Muslims are a good example of this process of integration, and today they …

Effects Of Bac On The Innervation Of Stomach, Berri̇n Gençer Tarakçi

Turkish Journal of Veterinary & Animal Sciences

Serosal application of BAC (benzalkonium chloride) to the pyloric antrum of the rat led to a complete loss of the intrinsic innervation of the treated region and also extensive loss of extrinsic sensory projections in the treated and untreated regions of the stomach. However, no changes were seen in the numbers of primary afferents projecting to the stomach, or expression of neuropeptides or neuronal proteins in the neurons. This finding is in marked contrast to the changes reported in sensory cell bodies after sectioning of the sciatic nerve, and suggested that visceral and somatic afferents may respond differently to axonal …

Development Of An Enzyme Immunoassay For The Determination Of Ovine Growth Hormone In Plasma, Behi̇ç Serpek, Seyfullah Hali̇loğlu

Turkish Journal of Veterinary & Animal Sciences

A competitive enzyme immunoassay for the determination of ovine growth hormone (oGH) was developed. The assay is based on (anti-rabbit IgG) goat IgG-coated microtitreplates, anti-oGH from rabbits, biotinyl-oGH and streptavidin-horseradish peroxidase. The assay is done directly with 40 ml of plasma and the calibration graph (90% relative binding at 0.38 ± 0.02 ng ml -1 and 50% relative binding at 3.80 ± 0.18 ng ml -1 ) is prepared in plasma without measurable endogenous oGH. Recovery in different plasma samples with added oGH amounted to 96.78 - 100.03 %, and all variabilities were < 10.44. The assay shows no significant binding of oFSH, oLH, oTSH and oPRL. The assay detects high and low plasma oGH levels within the physiological variation as well as changes in plasma oGH after stimulation with growth hormone releasing factor. Hence, it offers a reliable alternative radioimmunoassay. However, a reference method providing evidence of the identity of exogenous oGH will be required for proving illegal treatment with oGH and for forensic purposes.
