Structure And Functional Potential Of Microbial Communities In Subglacial Lake Whillans And At The Ross Ice Shelf Grounding Zone, West Antarctica, Amanda Marie Achberger
Structure And Functional Potential Of Microbial Communities In Subglacial Lake Whillans And At The Ross Ice Shelf Grounding Zone, West Antarctica, Amanda Marie Achberger
LSU Doctoral Dissertations
The abundance of liquid water found beneath the Antarctic Ice Sheet (AIS) is thought to provide a suitable habitat for microbial life. However, the thick ice sheet has posed a significant obstacle to accessing this isolated system and as a consequence, little data exists to infer ecosystem processes occurring beneath ice sheets. To address this deficit, data generated through 16S rRNA (genes and molecules) and metagenomic sequencing was used to evaluate the diversity and potential metabolic function of communities inhabiting Subglacial Lake Whillans (SLW) and the ocean basin into which it discharges (Whillans Ice Stream grounding zone; WIS-GZ). The analysis …
Transatlantic Trade And Investment Partnership: Implications To Global Wine Market, Natalia Antosova
Transatlantic Trade And Investment Partnership: Implications To Global Wine Market, Natalia Antosova
LSU Master's Theses
Transatlantic Trade and Investment Partnership was first introduced in 2013, with the goal of liberalization of the trade and investments, better coordination of trade by specific regulations, enhancing intellectual property protection and lifting government’s impediments to trade. This Thesis is concerned on potential implications of the TTIP on the wine industry in the European Union and particular consequences related to EU wine producers. The literature review of this paper is developed with the purpose to bring general knowledge in the matter of the TTIP. In addition, linkages of the TTIP with the political economy are provided in the latter part …
Developing And Characterization Of Catfish Skin Hydrolysates Including Antioxidant And Antimicrobial Properties, Cesar Augusto Galindo Perez
Developing And Characterization Of Catfish Skin Hydrolysates Including Antioxidant And Antimicrobial Properties, Cesar Augusto Galindo Perez
LSU Master's Theses
Catfish skin (CS) contains considerable amount of protein that may be hydrolyzed enzymatically to generate hydrolysates (CSH) which may have antioxidant and antimicrobial properties. The generation of natural compounds with these properties is of special interest to the food industry. The objective of this study was to develop and characterize CSH including antioxidant and antimicrobial properties. CSH were produced from different enzymatic reaction periods using alkaline protease, and their characterization, antioxidant, antimicrobial, and some functional properties were evaluated. A selected CSH was analyzed for peptide composition and partial amino acid sequences. The color analysis showed that darker, more yellow, and …
Effects Of Truck Based Ultra-Low Volume Mosquito Adulticides On Honey Bees (Apis Mellifera) In A Real World Scenario, Vivek Pokhrel
Effects Of Truck Based Ultra-Low Volume Mosquito Adulticides On Honey Bees (Apis Mellifera) In A Real World Scenario, Vivek Pokhrel
LSU Master's Theses
Honey bees are crucial pollinators for many economically important fruit crops. The recent honey bee colony decline in the United States and other regions of the world has caused concern among commercial beekeepers, research groups, the government, and the general public. The role of pesticides in recent honey bee declines has not been fully determined. In Louisiana, it is a common practice to spray truck based ultra-low volume mosquito adulticides in Integrated Mosquito Management Programs to control mosquitoes and minimize the risk of vector borne viruses such as West Nile, chikungunya, and Zika. This study measured the effects of truck …
Evaluation Of Ammonia Volatilization And Zinc Nutrition Of Experimental Zinc Sulfate Coated Urea Fertilizers In A Drill-Seeded Delayed Flood Rice Production System, Nutifafa Adotey
LSU Doctoral Dissertations
Approaches in controlling nitrogen (N) loss from preflood fertilizer applications in delayed flood rice (Oryza stiva) production in the mid-southern U.S.A. typically involves treating urea with urease inhibitors like N-(n-butyl) thiophosphoric triamide (NBPT). Limited research exists on managing N utilizing the combined effects of treating urea with a urease inhibitor and subsequently adding a physical zinc (Zn) sulfate coating. Zinc deficiency is also a major soil fertility constraint in flooded rice production. The objectives of this study were to: (i) determine the ammonia volatilization potential of experimental zinc sulfate coated urea (ZSCU) fertilizers on four rice soils in a controlled …
Integration Of Optical Remote Sensor-Based Yield Prediction And Impact Of Nitrogen Fertilization, Harvest Date, And Planting Scheme On Yield, Quality, And Biomass Chemical Composition In Energy Cane Production In Louisiana, Marilyn Sebial Dalen
LSU Doctoral Dissertations
The established sugarcane industry in Louisiana is perceived as an advantage for biofuel industry because of the similarities of energy cane and sugarcane by way they are cultivated, harvested, and processed. This study was conducted at the LSU AgCenter Sugar Research Station in St. Gabriel, LA from 2013-2015 to evaluate the influence of planting scheme, N rate, and harvest date on energy cane yield, quality parameters, nutrient uptake, and biomass chemical composition. The relationship of vegetation indices (VI) with stalk, fiber yield, and N uptake of energy cane harvested at different dates was also evaluated. The experiments consisted of variety …
Combining Forage And Cover Crop Benefits From Cool-Season Annuals In The Southeastern United States, Dustin John Smith
Combining Forage And Cover Crop Benefits From Cool-Season Annuals In The Southeastern United States, Dustin John Smith
LSU Master's Theses
Cow-calf operations in the southeastern United States (U.S.) are based on warm-season perennial grass pastures. Stored forage feeding during the non-grazing season constitutes more than half of a cattle operation’s annual expenses. Cool-season annuals can extend the grazing season, thereby reducing stored forage feeding. A two-year field trial was conducted to determine the forage potential of a variety of crops commonly used as winter cover crops in the southeastern U.S. The ten cover crop treatments included seven monocultures (annual ryegrass [Lolium multiflorum], rye [Secale cereal], oats [Avena sativa], triticale [Triticale hexaploide], tillage radish [Raphanus sativus], hairy vetch [Vicia villosa], crimson …
