Using Stormwater Modeling In Iterative Site Design: An Integration Of Techniques From Engineering And Landscape Architecture, Brooke Erin Morris Jan 2015

Using Stormwater Modeling In Iterative Site Design: An Integration Of Techniques From Engineering And Landscape Architecture, Brooke Erin Morris

LSU Master's Theses

Landscape Architects currently do not have an efficient method for including stormwater quantities in early stages of their design process. With stormwater control infrastructure and theory rapidly shifting in favor of stormwater management with Green Infrastructure or Low Impact Development technologies (LIDs), landscape architects and planners are increasingly making layout and sizing decisions for stormwater design. Due to the development of modeling tools, it is now possible to rapidly produce quantifiable stormwater values for complex site designs at a range of scales. This paper proposes a methodology for the utilization of the EPA – Stormwater Management Model (SWMM), in conjunction …

Toxic Landscapes, Environmental Justice, And The Community: An Assessment Of Citizen Participation In Superfund Site Remediation Across Vulnerable Populations, Simone Justine Domingue Jan 2015

Toxic Landscapes, Environmental Justice, And The Community: An Assessment Of Citizen Participation In Superfund Site Remediation Across Vulnerable Populations, Simone Justine Domingue

LSU Master's Theses

The environmental justice movement has made progress toward unveiling environmental inequalities and addressing these inequalities through the empowerment of low-income and minority communities. Federal agencies like the EPA have incorporated environmental justice principles into their operating frameworks, with the goals of ensuring every community is treated similarly when it comes to the implementation of environmental statutes, and ensuring community members are active participants in environmental activities that affect community well-being. Community involvement at federal Superfund sites is rarely conceptualized as an event related to environmental justice despite the role it has in shaping decisions at hazardous waste sites.

Social Anxiety And Cannabis-Related Impairment: The Roles Of Anxiety Sensitivity And Intolerance Of Uncertainty, Emily Robin Jeffries Jan 2015

Social Anxiety And Cannabis-Related Impairment: The Roles Of Anxiety Sensitivity And Intolerance Of Uncertainty, Emily Robin Jeffries

LSU Master's Theses

Cannabis use is associated with many negative consequences. Identification of factors associated with cannabis could inform prevention and treatment efforts. Social anxiety appears to be one risk factor for cannabis-related problems. Thus, it is important to identify malleable cognitive vulnerability factors that may play a role in the social anxiety-cannabis problems relationship. Anxiety sensitivity (AS) is the fear of anxiety-related bodily sensations and is composed of three subfacets: physical, cognitive, and social concerns. AS is associated with greater social anxiety and may play a role in cannabis-related impairment. Intolerance of uncertainty (IU) refers to a tendency to respond negatively to …

Analyzing Site Suitability For Baldcypress (Taxodium Distichum) Regeneration Along A Hydrologic Gradient In South Louisiana Swamps, Marcus Rutherford

LSU Master's Theses

The future of Louisiana’s coastal cypress-tupelo forests is threatened by prolonged or permanent flooding during the growing season. Permanent inundation prevents baldcypress seedlings from becoming established. The upper limit of submergence with respect to adequate planted baldcypress seedling performance has not been effectively tested under actual field conditions. Similarly, an effective method for determining a site’s regeneration potential based on present vegetation attributes has not been developed. To test first-year performance of planted baldcypress seedlings under varying levels of submergence, I planted 900 of both 1-0 and 2-0 age-class bare-root seedlings across 12 different sites covering a range of hydrologic …

Hybridization And Population Structure Of Western Gulf Coast Mottled Ducks, Robert Joseph Ford Jan 2015

Hybridization And Population Structure Of Western Gulf Coast Mottled Ducks, Robert Joseph Ford

LSU Master's Theses

Rates of hybridization between species that do not normally interbreed have increased due to human impacts on natural environments, such as habitat alteration or introductions of non-native species. Human-induced hybridization can be detrimental to wildlife and contribute to species extinctions. In Florida, feral Mallards (Anas platyrhynchos) hybridize with endemic Mottled Ducks (A. fulvigula) at rates close to 9%. However, levels of hybridization between these two species have not been extensively examined in the western Gulf Coast (from Alabama to northern Mexico) despite the potential impact on the Mottled Duck lineage. In this study, I examined the degree of hybridization between …

Herbivore Response To Soybean Under Differing Induction Methods, John L. Dryburgh Jan 2015

Herbivore Response To Soybean Under Differing Induction Methods, John L. Dryburgh

LSU Master's Theses

Plants are attacked by a variety of herbivore feeding guilds and respond with specific responses to specific attacks, which may be localized or systemic. How a plant defends against one feeding guild may alter the plant’s response against a different feeding guild. A better understanding of these interactions will allow for the development of refined pest management programs. One situation in which this may occur is in interactions between chewing and piercing/sucking herbivores, such as aphids. Aphids are important crop pests primarily due to their ability to transmit viruses, the efficacy of which can be affected by plant defenses. To …

Evaluating The Effects Of Vacuum Tumbling With Chitosan Nanoparticles And Water-Soluble Chitosan On The Shelf Life Of Cryogenically Frozen Shrimp, Alexander Chouljenko Jan 2015

Evaluating The Effects Of Vacuum Tumbling With Chitosan Nanoparticles And Water-Soluble Chitosan On The Shelf Life Of Cryogenically Frozen Shrimp, Alexander Chouljenko

LSU Master's Theses

Chitosan (CH) is a biopolymer obtained from the deacetylation of chitin, a polysaccharide present in the exoskeleton of crustaceans and cell walls of fungi. Application of CH may be limited by its water-insolubility. It can be dissolved in acids and forms relatively high viscosity solutions. CH solutions have antioxidant and antimicrobial properties. CH penetration into shrimp may be facilitated by vacuum tumbling with low viscosity chitosan-sodium tripolyphosphate (CH-TPP) nanoparticle or water-soluble chitosan (WSC) solutions. It is expected that this would reduce lipid oxidation and microbial loads. In this study, CH-TPP and WSC solutions were developed and applied to shrimp, and …
