Altering Sweet Potato Starch Functionality By Amino Acids And Ph Treatments, Jonathan Futch
Altering Sweet Potato Starch Functionality By Amino Acids And Ph Treatments, Jonathan Futch
LSU Master's Theses
The sweet potato is a vegetable containing high levels of different vitamins and minerals, needed to protect the body against disease. This study focused on starch found in the Beauregard and Evangeline sweet potatoes and observed the effect of pH and amino acid additives altering the functionality of starch. These modifications of the Beauregard and Evangeline sweet potato starches will also be done to determine if an increase in resistant starch and slowly digestible starch is found. Beauregard and Evangeline starches had similar gelatinization temperature and the two starches required the same amount of energy to gelatinize. In Freeze-dried Beauregard …

Effect Of Rotational Or Continuous Stocking Method Of Winter Pasture On Beef Heifer Performance, David G. Skeans
LSU Master's Theses
Considerable research has been conducted comparing the effect of continuous and some form of rotational stocking method on animal and forage performance, but most research utilizes put-and-take stocking rates. The purpose of this research was to determine the effect of 12-paddock rotational stocking method (ROT) or continuous stocking method (CONT) of winter wheat (Triticum aestivum) and annual ryegrass (Lolium multiflorum) pastures on beef heifer and forage performance while maintaining a continuous stocking rate of 3.7 heifers/ha. Two experiments were conducted and analyzed separately due to confounding year and location. Heifer ADG and WG/ha tended to be increased by ROT compared …

Pulsed Electric Field Influences On Acid Tolerance, Bile Tolerance, Protease Activity And Growth Characteristics Of Lactobacillus Acidophilus La-K, Olga Antonina Cueva
LSU Master's Theses
Pulsed electric field processing represents a promising non-thermal technology which involves the application of pulses of high voltage (20-80 kV/cm) for less than one second to fluid foods placed between two electrodes. During the application of certain PEF conditions microbial inactivation occurs by causing a pore formation and destruction of the cell membranes. Lactobacillus acidophilus is an important probiotic bacterium used for the production of fermented dairy products. The objective of this study was to study the influence of pulsed electric field (PEF) on the growth characteristics, bile tolerance, acid tolerance, and protease activity of Lactobacillus acidophilus LA-K. Freshly thawed …
Determining Gene Copy Number In Transfected Caprine Fibroblast Cells, Jessica A. Wilson
Determining Gene Copy Number In Transfected Caprine Fibroblast Cells, Jessica A. Wilson
LSU Master's Theses
Transgene expression in stably transgenic organisms is affected by many factors, including the copy number of the transgene in the genome, and by interactions between the transgene and flanking DNA sequences. Transgene copy number has also been shown to effect genetic stability in transgenic plants. Two commonly used methods for transfecting cells are liposome mediated transfection and electroporation. Little is known about the mean transgene copy number or variability of the copy number with these techniques. Quantitative PCR (Q-PCR) has been shown to be an effective method for determining transgene copy number. The objective of this study was to determine …
Comparisons Of Physicochemical Properties Of Watermelon Juice Treated With Pulsed Electric Fields And Thermal Pasteurization, Lauren Nicole Cook
Comparisons Of Physicochemical Properties Of Watermelon Juice Treated With Pulsed Electric Fields And Thermal Pasteurization, Lauren Nicole Cook
LSU Master's Theses
Pulsed electric field (PEF) treatment is a non-thermal and alternative pasteurization treatment for fruit juices. PEF applies short pulses of electricity to a liquid food sample which inactivates microorganisms and enzymes. Thermal pasteurization is commonly used to pasteurize juice in the fruit juice industry but the process tends to deteriorate color, nutrients, and overall juice appearance. The overall goal of this study was to determine the effects of PEF treatment (30 kv/cm for 57 ìs in bipolar 2 ìs pulses at 22°C) on color, lycopene content, vitamin C content, pH, °Brix, and microbial count when compared with the effects of …

An Evaluation Of Endurance And Combined Endurance And Resistance Training On Fitness And C-Reactive Protein, Laura A. Daray
LSU Master's Theses
PURPOSE: This study was designed to determine whether endurance or endurance + resistance training would influence circulating C-reactive protein (CRP) levels and if these changes are related to alterations in aerobic fitness and/or body composition. METHODS: Fifty eight healthy young adults aged 18-24 yrs (78% female) were assigned to one of three groups: 1) endurance training (E) (n=18), 2) endurance + resistance training (ER) (n=11), or 3) active control (AC) (n=29). The E group completed 15 weeks of endurance training for either a half marathon (n=6) or full marathon (n=12). The ER group performed 15 weeks of periodized resistance training …

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 …
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 …
A Critical Examination Into Motivation And Gender In Youth Physical Fitness Testing, Elizabeth A. Domangue
A Critical Examination Into Motivation And Gender In Youth Physical Fitness Testing, Elizabeth A. Domangue
LSU Doctoral Dissertations
Fitness testing in physical education classes has emerged as an important component in efforts to assess and address health concerns related to children’s physical inactivity. To date, motivational aspects of fitness testing, especially in regard to students’ future intention to participate in fitness-related activities, have not been closely examined. Fitness testing practices have been identified as a dominant discourse in physical education that continue to separate girls’ and boys’ physicalities along gendered lines. This lack of understanding about the motivational implications of fitness testing programs, coupled with concerns related to the gendered nature of fitness testing, emphasize the significance of …

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, …
