The Role Of Teachers' Self-Efficacy In Increasing Children's Physical Activity, James Frederick Roth

LSU Doctoral Dissertations

It is well documented that elementary school children do not participate in recommended amounts of physical activity, and that elementary physical education programs generally are unable to insure that children engage in appropriate amounts of activity. One solution to this dilemma is to increase children’s activity levels through collaborative efforts such as whole school programs involving the classroom teachers. If this approach is to be successful, it is important to investigate ways that elementary classroom teachers can be actively involved in school level programs that will ultimately increase children’s physical activity levels. Elementary classroom teachers are often responsible for at …

Health And Lifestyle Profiles Across The Lifespan: Results From The Louisiana Healthy Aging Study, Madlyn Irene Frisard

LSU Doctoral Dissertations

Aging and age related disease affects individuals differently. One possible explanation could be free radical production varies among individuals and this variation determines the aging process and the progression of disease. The purpose of this study was to test whether nonagenarians have a relatively low metabolic rate when compared to younger individuals and whether this low metabolic rate is associated with lower levels of oxidative stress and less incidence of disease. Resting metabolic rate (RMR), markers of oxidative stress to lipids, proteins, and DNA, components of the metabolic syndrome, and physical activity level were measured in 3 groups of individuals …

Amino Acid Requirements And Low Crude Protein, Amino Acid Supplemented Diets For Swine And Poultry, Dustin Wade Dean

LSU Doctoral Dissertations

The purpose of this research was to determine requirements for amino acids that limit the use of crystalline amino acids, to determine the effects of reducing crude protein, and to evaluate the problems associated with low crude protein diets for swine and poultry. Four experiments were conducted to determine the Lys and sulfur amino acid requirements for 5- to 10-kg pigs. The results of these experiments suggest pigs in this weight range require a diet containing 1.40% true digestible (TD) Lys and the ratio of sulfur amino acids to Lys is not greater than 0.54. Two experiments were conducted to …

The Presence Of Plasmodium Falciparum Gametocytes In Human Blood Increases The Gravidity Of Anopheles Gambiae Mosquitoes, Heather M. Ferguson, Louis C. Gouagna, Peter Obare, Andrew F. Read, Hamza Babiker, John Githure, John C. Beier

All Peer-Reviewed Publications

We conducted a field study in an area of endemic malaria transmission in western Kenya to determine whether mosquitoes that feed on gametocyte-infected blood but do not become infected have reduced or enhanced fecundity in comparison to mosquitoes fed on uninfected blood. Fifteen paired membrane-feeding experiments were conducted in which two strains of Anopheles gambiae mosquitoes were simultaneously fed on either Plasmodium falciparum-infected blood from children or uninfected control blood from adults. The presence of noninfecting gametocytes in blood increased the probability that An. gambiae would produce eggs after one blood meal by sixfold (odds ratio for control relative to …

Hydrogeology Of Hanging Bog State Preserve: The Role Of Hillside Seeps In Draining The Iowan Surface, William L. Niemann

Journal of the Iowa Academy of Science: JIAS

Along the margin of the Cedar River Valley, groundwater discharges from eroded and weathered glacial materials of the Iowan Surface to modern alluvial deposits of the valley floor. Hanging Bog State Preserve, located along this topographic, geologic, and hydrologic boundary, represents one such groundwater discharge location, in the form of a perennial hillside seep. Based on detailed monitoring of surface water and groundwater levels within the preserve for a one-year period, it is shown that a significant quantity of groundwater, collected from a disproportionately large recharge area, is funneled to the valley wall at this site and subsequently carried to …

Cultivation Of Mesophilic Soil Crenarchaeotes In Enrichment Cultures From Plant Roots, Holly M. Simon, Courtney E. Jahn, Luke T. Bergerud, Marek K. Sliwinski, Paul J. Weimer, David K. Willis, Robert M. Goodman

Faculty Work

Because archaea are generally associated with extreme environments, detection of nonthermophilic members belonging to the archaeal division Crenarchaeota over the last decade was unexpected; they are surprisingly ubiquitous and abundant in nonextreme marine and terrestrial habitats. Metabolic characterization of these nonthermophilic crenarchaeotes has been impeded by their intractability toward isolation and growth in culture. From studies employing a combination of cultivation and molecular phylogenetic techniques (PCR– single-strand conformation polymorphism, sequence analysis of 16S rRNA genes, fluorescence in situ hybridization, and real-time PCR), we present evidence here that one of the two dominant phylotypes of Crenarchaeota that colonizes the roots of …

A Study Of The Abundance, Distribution And Daily Activities Of The Australian Raven (Corvus Coronoides) In Urban Wetland Parks, Desiree L. Moon

Theses : Honours

Habitat destruction as a result of urbanisation has resulted in the population decline of some bird species. However, the Australian Raven (Corvus coronoides), has adapted well to the urban environment and is thriving. Although naturally occurring seasonal food sources are at times restricted in an urban setting, this adaptive species finds alternative food sources. As carrion-eaters this includes roadkill, as well as refuse discarded on the ground and into bins. Coupled with few natural predators, the species enjoys optimal conditions for breeding and survival. This biogeographical study investigated whether seasonal-influxes of populations of ravens cause problems at three urban wetland …

The Effect Of Antioxidant Supplementation On Human Sperm Cryopreservation, Katrina E. Taylor

Theses : Honours

Semen cryopreservation has an important role in assisted reproductive technology however, the cooling, freezing and thawing processes often result in a significant loss of sperm motility, viability and nuclear integrity. The destructive effects of cryopreservation are significantly exacerbated in samples exhibiting low sperm number and poor morphological characteristics. Recent research into infertility has focused on the correlation between excessive oxidation and subfertility, in particular radical induced lipid peroxidation within the phospholipid bilayer of the spermatozoon plasma membrane and the promotion of cellular damage as a result of antioxidant insufficiency. The aim of this study was to evaluate the effect of …

A Study Of The Effects Of Probait On Chuditch, Dasyurus Geoffroii, Within The Julimar Conservation Park With Notes On The General Ecology, Melissa York

Theses : Honours

Broad scale fox baiting programs have been underway in Western Australia since 1996 when the Western Shield fauna recovery program commenced with the aim of recovering many fauna species that are under threat of extinction. Until recently, effective fox control for fauna recovery has been achieved with dried meat baits impregnated with the poison 1080. The Department of Conservation and Land Management (CALM) has developed more readily available and cost effective sausage meat baits, termed Probait. As bait acceptability trials in the laboratory indicated a potential risk from Pro bait ingestion by chuditch (Dasyurus geoffroii), assessment of the likely risk …

Synthesis And Characterization Of Membrane Anchored Peptides, Eugenia Christine Tsamis

Honors Program Theses

ln KW ALP23 peptides containing Lysine and Trp, as the Trps were moved further in towards the center of the bilayer, Lys became the dominant anchoring residue (1). The goal of this project was to determine whether Arg exhibits snorkeling behavior similar to Lys, and is able to anchor the peptide in the membrane despite the repositioning of Trp in the RWALP peptides. Several candidate R W ALP23 peptides containing Tryptophan and Arginine with an alternating LeucineAlanine backbone were synthesized successfully. They were then studied by HPLC, CD, and MALDI-TOF Mass Spectrometry to investigate the anchoring roles of Arg and …

The Effects Of Cadmium On Levels Of Glucose In Serum And Glycogen Reserves In The Liver And Muscle Tissues Of Cyprinus Carpio (L., 1758), Bedi̇i̇ Ci̇ci̇k, Kenan Engi̇n

Turkish Journal of Veterinary & Animal Sciences

The common carp (Cyprinus carpio L., 1758) was exposed to sublethal concentrations of cadmium (0.05, 0.1, 0.5 and 1.0 mgl^{-1}) for 10 days. The levels of serum glucose and glycogen reserves in the liver and muscle tissues were measured both in fish exposed and not exposed to Cd. The levels of glycogen reserves in the liver and muscle tissues were significantly (P < 0.05) decreased in fish exposed to sublethal concentrations of Cd compared with the levels measured in the control groups. The decrease in glycogen levels in the liver and muscle tissues under the highest metal concentration (1.0 mgl^{-1}) were 24% and 29%, respectively. The blood serum glucose levels of fish exposed to Cd were significantly (P < 0.05) increased compared with the levels measured in the control groups. This increase was correlated with the increase in water Cd concentrations.

Effects Of Heavy Metal Accumulation On The 96-H Lc_50 Values In Tench Tinca Tinca L., 1758, Syed Lal Shah, Ahmet Altindağ

Turkish Journal of Veterinary & Animal Sciences

The effects of already accumulated heavy metals (Hg, Cd, Pb) in the body of tench on the 96-h LC_50 values of the respective heavy metals were studied. The body concentration of mercury, cadmium and lead was 0.011, 0.32 and 1.59 mg/g respectively, and their 96-h LC_50 values were 1.0, 6.5 and 300.0, ppm, respectively. The general accumulation order of heavy metals and their respective 96-h LC_50 values were Hg< Cd< Pb. It was observed that the fish with lowest body concentration of heavy metal showed the lowest 96-h LC_50 value of the respective heavy metal and vice versa. This close relationship showed that the previous body accumulation of heavy metals has a direct effect on the 96-h LC_50 values of the respective heavy metals and the susceptibility of fish.

Altering The Lactation Cycle: Is A 60-Day Dry Period Too Long?, Mehmet Şükrü Gülay

Turkish Journal of Veterinary & Animal Sciences

The most critical problem for the evaluation of different dry period lengths is the relationship between days dry and subsequent milk production. It is assumed that when a cow is dried off, the loss in the current lactation will be compensated for by greater milk production during the following lactation. However, the process of parturition and initiation of lactation are extremely important events and they are associated with many problems that may result in removal of the individual cow from the herd or in greatly reduced milk production, especially early in the lactation. Therefore, identification of the shortest possible dry …
