Does Practice Of Multi-Directional Stepping With Auditory Stimulation Improve Movement Performance In Patients With Parkinson's Disease, Zahra Kadivar
Does Practice Of Multi-Directional Stepping With Auditory Stimulation Improve Movement Performance In Patients With Parkinson's Disease, Zahra Kadivar
LSU Doctoral Dissertations
Parkinson’s disease (PD) is a debilitating neurodegenerative disorder causing many physical limitations. Rhythmic auditory stimulation (RAS) influences motor complications not alleviated by medicine and has been used to modify straight line walking in this population. However, motor complications are exacerbated during more complex movements including those involving direction changes. Thus immediate RAS effects on direction switch duration (DSD) and other kinematic measures during a multi-directional step task were investigated in PD patients. Long term RAS application was also explored by evaluating functional gait and balance and kinematic step measures before and after 6 weeks of multi-directional stepping either with (Cue, …
Characterization Of The Common Eland (Taurotragus Oryx) Estrous Cycle, Parker M. Pennington
Characterization Of The Common Eland (Taurotragus Oryx) Estrous Cycle, Parker M. Pennington
LSU Master's Theses
Three oryx species and nine of eighteen antelope species across three tribes are considered endangered by the IUCN. Though the common eland (Taurotragus oryx) is not endangered, it lends itself well to the adaption of domestic assisted reproductive techniques due to its large size and calm temperament (Hansen et al., 1985). For these techniques to be used efficiently however, the details of the estrous cycle need to be defined within this and other species. Previously, Nowak (1999) proposed the eland estrous cycle to be ~21 days. In addition to cycle length, specifics of the estrous cycle have yet to be …
Characterization Of Porcine Adipose Tissue-Derived Stem Cells, Kellie J. Williams
Characterization Of Porcine Adipose Tissue-Derived Stem Cells, Kellie J. Williams
LSU Doctoral Dissertations
Nuclear transfer (NT) results in low success rates and research has reported problems with the welfare of cloned animals produced. Evidence suggests the use of a less differentiated donor cell, such as a stem cell, may lead to an increase in the efficiency of the NT procedure. Stem cell characteristics must be clearly defined in order to isolate, identify and optimally culture potential donor cells. Stem cell characteristics such as self-renewal and differentiation have not been identified in stem cells from porcine adipose tissue, an easily attainable tissue resource. The phenotypic profile of cell surface proteins and chromosomal stability of …

Isoflavone Distribution In Soy Seed And Antioxidant Activity Of Defatted Soy Flour Extract, Xiaohua Yue
LSU Doctoral Dissertations
Soy isoflavones distribution in soy cotelydon, coat and germ were determined. The ƒÀ-Glucoside form of isoflavones was the major class of isoflavones in all three soy parts. Soy germ was the richest source of the isoflavones among the three soybean parts. Distribution of the isoflavones in soy cotyledon was different from that in soy coat or germ. As defatted soy flour is a main byproduct in the soy oil refining process, utilizing the low value byproduct as a valuable food antioxidant was investigated in this study. The level of isoflavones in the defatted soy flour extract was 55 mg/g, which …
Essays On Environmental Issues Associated With The Diary Production Region In Louisiana, Larry Michael Hall
Essays On Environmental Issues Associated With The Diary Production Region In Louisiana, Larry Michael Hall
LSU Doctoral Dissertations
The Louisiana dairy production region (LDPR) is located in southeast Louisiana and includes five parishes (Tangipahoa, Washington, Livingston, St. Helena, and St. Tammany). It is home to approximately 90% of the state’s dairy industry and is a major contributor to nonpoint source pollution (NPS) in the area’s watershed through nitrogen, phosphorus, and sediment effluents. While point source (PS) effluents are easily identified and subject to federal and state regulations, NPS mitigation efforts must address uncertainties such as location of the NPS as well as stochastic parameters such as rainfall and its effect on nutrient and sediment flow. This dissertation presents …
Biophysical Economic Analysis Of Nutrient And Sediment Management Practices In The Mississippi Alluvial Valley, Augustus Nyako Matekole
Biophysical Economic Analysis Of Nutrient And Sediment Management Practices In The Mississippi Alluvial Valley, Augustus Nyako Matekole
LSU Doctoral Dissertations
Conventional drainage systems and poorly drained soils tend to increase row crop agriculture nutrient and sediment effluent loads. Best management practices help reduce row crop production environmental pollution. This dissertation looked at nutrient and tillage management practices that could help farmers address future total maximum daily loads (TMDLs) for the Cabin-Teele sub-watershed, within the lower Mississippi River Basin. The dissertation had two objectives. The first objective was to examine the economic and environmental impact of tillage and nutrient management practices in reducing agricultural pollutants to meet TMDL requirements. Relative cost effectiveness of different tillage and nutrient management practices were analyzed …
An Analysis Of Government Policy Impacts In The Ethanol And Sugar Markets, Hassan Marzoughi_Ardakani
An Analysis Of Government Policy Impacts In The Ethanol And Sugar Markets, Hassan Marzoughi_Ardakani
LSU Doctoral Dissertations
ABSTRACT This study determines the impact of U.S. government policies on U.S. ethanol market and its consequences for the U.S. corn, sugar, and HFCS markets. Using corn as the primary input in ethanol and HFCS production in the United States, along with the substitutability between sugar and HFCS, has linked the U.S. ethanol market to the U.S. HFCS, sugar, and corn markets. To address the problem, two sets of data, quarterly and annual data, were collected and a simultaneous econometric model was constructed. Estimated results show that the “2007 Energy Independence and Security Act” will increase the domestic corn price …
The Expansion And Diversification Of The Export Sector And Economic Growth: The Costa Rican Experience, Gustavo Filipe Canle Ferreira
The Expansion And Diversification Of The Export Sector And Economic Growth: The Costa Rican Experience, Gustavo Filipe Canle Ferreira
LSU Doctoral Dissertations
A large body of empirical literature has investigated the linkages between exports and output. Nevertheless, empirical evidence remains inconclusive and the topic remains open to discussion. Additionally, a number of studies have examined the positive effects that export diversification may have on economic growth. Within the Latin America region, Costa Rica has been lauded for its long democratic tradition, relative economic stability, and for evolving from being a small economy heavily reliant on exports of coffee and bananas, to become the largest software exporter per capita in Latin America. This study examined the impact that the expansion and diversification of …
Three Essays On The World Rice Market: A Structure, Conduct, And Performance Paradigm Approach, Hyunsoo Kang
Three Essays On The World Rice Market: A Structure, Conduct, And Performance Paradigm Approach, Hyunsoo Kang
LSU Doctoral Dissertations
In the past several decades, the international rice market has undergone major changes experiencing a strong expansion in traded volumes and in the volatility of rice prices. International rice prices are, furthermore, expected to remain at relatively high levels because of higher fertilizer and fuel prices, especially as stocks held by those exporters still allow unrestrained sales. With this instability in the world rice market, we need to consider the structure, conduct, and performance (S-C-P) of the world rice market. The main objective of this dissertation will be to examine the world rice market based on S-C-P methods. This dissertation …

The presence of mercury in the U.S. fish supply is a growing public health concern. At high levels, mercury can be harmful to humans and ecosystems, and represents a growing threat not only to public health, but also to the economic and ecological viability of many fisheries. This research examined the economic issues surrounding mercury contamination in fish, developed a population dynamics and bioeconomic model to investigate the problem, and compared a variety of management actions to reduce consumer exposure to contaminants. The dissertation begins with an overview of contamination issues in U.S. fisheries, including a review of the historical …
Three Essays On Environmental Issues Associated With Broiler Production In Louisiana, Nirmala Adhikari Devkota
Three Essays On Environmental Issues Associated With Broiler Production In Louisiana, Nirmala Adhikari Devkota
LSU Doctoral Dissertations
The increasing trends of integrated and concentrated broiler production results in a serious threat to environment through excessive litter production and lack of its proper disposal. Production concentration in limited area is a major source of surface as well as ground water pollution. Nonpoint source pollution from broiler litter applied on land remains a major concern in Louisiana and elsewhere in Southeastern USA. This study examines alternative approaches to reduce pollution originating from broiler production. First, I evaluate why some producers adopt BMP faster than others and what kind of factors affect the time to adoption decision. The duration model …

Categorization And Indentification Of Mechanisms Of Sugarcane Resistance To The Sugarcane Aphid (Hemiptera: Aphididae), Waseem Akbar
LSU Doctoral Dissertations
Sugarcane in Louisiana is colonized and sometimes heavily infested by two aphid species, the sugarcane aphid, Melanaphis sacchari (Zehntner), and the yellow sugarcane aphid,Sipha flava(Forbes). Melanaphis sacchari, the main vector of sugarcane yellow leaf virus, is distributed throughout Louisiana’s sugarcane-growing regions. Five cultivars representing 90% of the commercial acreage in Louisiana (LCP 85-384, HoCP 91-555, Ho 95-988, HoCP 96-540,L 97-128) were evaluated for resistance to aphids in the greenhouse. Antibiosis was the primary category of resistance to both aphid species. Based on the intrinsic rate of natural increase, L 97-128 and HoCP 91-555 were comparatively susceptible and resistant cultivars, respectively. …

LSU Doctoral Dissertations
This research was conducted with broilers to investigate the interactive effects of P and Ca on P requirement, digestibility, utilization, and phytase efficacy. Each treatment had a minimum of 6 replications. One experiment with 3 trials was conducted to identify the nonphytate P (nPP) requirement of 0 to 14 d old broilers. The nPP levels fed ranged from 0.30 to 0.60% with a Ca:nPP of 2.22:1 or 1.9:1. Requirement estimates for 0 to 14 d ranged from 0.52 to 0.60% nPP. One experiment with 2 trials was conducted to identify the nPP requirement of 14 to 28 d old broilers. …
Dose Titration Of Sericea Lespedeza Leaf Meal On Haemonchus Contortus Infection In Crossbred Lambs, Dana Alicia Pollard
Dose Titration Of Sericea Lespedeza Leaf Meal On Haemonchus Contortus Infection In Crossbred Lambs, Dana Alicia Pollard
LSU Master's Theses
Gastrointestinal nematode (GIN) parasitism is a problem for small ruminant producers. Haemonchus contortus is the most detrimental because of substantial economic losses. Over the past decades, chemical anthelmintics have been used to control GINs. Recently, GINs have developed resistance to most anthelmintics, and now reliance on anthelmintics is not possible. Alternative control methods are needed. Also, the use of fewer chemicals in agricultural products has called for alternative methods to be less synthetic and more organic. One promising alternative method is the feeding of condensed tannin (CT) containing forages as either fresh forage or dried products such as hay, ground …
Does Acute Passive Stretching Alter The Optimum Height For Drop Jumping?, Jonathan Samuel Ritchie
Does Acute Passive Stretching Alter The Optimum Height For Drop Jumping?, Jonathan Samuel Ritchie
LSU Master's Theses
The application of static stretching (SS) has previously been shown to limit performance in force production, reaction time, balance and vertical jump height. When looking at the effect of SS on jump performance, researchers have previously used changes in jump height, in squat jumps (SQ), countermovement jumps (CMJ) and drop jumping (DJ) from self selected heights. To date no one has looked at the effect of SS across a range of drop heights. 30 subjects (15 male and 15 female) participated in 1 familiarization trial and four performance trials. All subjects undertook two days of stretching (ST) and two days …
