Breaking Coastal Hypoxia: Destratification Of Gulf Of Mexico Deadzone To Encourage Oxygen Transport Downwards To Maintain Marine Fauna, Veda Thipparthi
Breaking Coastal Hypoxia: Destratification Of Gulf Of Mexico Deadzone To Encourage Oxygen Transport Downwards To Maintain Marine Fauna, Veda Thipparthi
LSU Master's Theses
As a consequence of seasonal eutrophication and human input, a vast hypoxic area termed The Dead Zone develops every year in the Gulf of Mexico (GOM) during summer along the Louisiana coastline characterized by vertical seawater density-stratification with oxygen concentrations less than 2 mg.l-1 at the seafloor. It poses a threat to bottom-dwelling faunae and their environment which has negative ecological and economic consequences. This project aims to mitigate hypoxia by employing mechanical impellers placed at strategic water depths and locations in the Gulf. Enhanced transport of oxygen results by mixing oxygen-enriched seawater at the surface, downward into the …
Impacts Of Updated Design Rainfall Values On Louisiana Infrastructure, Mario Durbic
Impacts Of Updated Design Rainfall Values On Louisiana Infrastructure, Mario Durbic
LSU Master's Theses
The Louisiana Department of Transportation and Development (LADOTD) has a Hydraulics Manual which sets forth drainage design standards and codes for projects. The Manual contains maximum annual 24-hour rainfall maps and Intensity-Duration-Frequency (IDF) curves for the return periods of 2, 5, 10, 25, 50, and 100 years. The Manual divides Louisiana into three regions and specifies that all of the cities within a given region should use the same estimated rainfall intensities and rainfall depths. NOAA Atlas 14, the Precipitation-Frequency Atlas of United States, contains the latest rainfall data and statistics for much of the United States and provides the …

Perils Of The Fungal Kingdom: Mycotoxins In Food And Feed, Adrianna Isobel Pribil
LSU Master's Theses
Humans and fungi have a complex relationship, especially in regards to the many fungal secondary metabolites that can be produced. When secondary metabolites are toxic to animals and humans they are defined as mycotoxins. Fungi can grow on crops pre-harvest and post-harvest, and have the potential to produce mycotoxins which occur regularly in animal feed and food for human consumption. In high doses, mycotoxins cause variety of problems that result in economic losses and extreme health issues. However, multiple mycotoxins will co-occur in nature and commonly occur in low doses. Thus chronic low daily doses of multiple mycotoxins overtime may …
