Temporal And Spatial Trends Of Dead Copepods In The Northern Gulf Of Mexico In Relation To The Deepwater Horizon Oil Spill, Jessica L. Tolan May 2020

Temporal And Spatial Trends Of Dead Copepods In The Northern Gulf Of Mexico In Relation To The Deepwater Horizon Oil Spill, Jessica L. Tolan

LSU Master's Theses

Zooplankton are a critical link between primary producers and higher trophic levels in the marine environment. They play a critical role in carbon cycling, are an important food source for commercially important species, and are excellent indicator genera for environmental changes that take place in marine ecosystems. This research quantified temporal and spatial patterns of dead copepods in response to the Deepwater Horizon Oil Spill (DWH) site using ZooSCAN imaging technologies. Research showed that the proportion of dead copepods (showed evidence of decay but no physical damage due to predation) increased with depth, and at time periods closest to the ...


An Investigation Of Athletic Buoyancy In Adult Recreational And Sport Club Athletes, Jackie Rae Victoriano Calhoun May 2020

An Investigation Of Athletic Buoyancy In Adult Recreational And Sport Club Athletes, Jackie Rae Victoriano Calhoun

LSU Doctoral Dissertations

Athletic buoyancy is the ability of an athlete to effectively handle the daily setbacks and challenges they face during training and competition. Although buoyancy has received ample research in the academic domain, a dearth of information exists regarding buoyancy in the athletic domain. Therefore, the overall purpose of this dissertation was to investigate athletic buoyancy’s independent contribution to sport psychology while also exploring antecedents and outcomes in adult athletes.

Study 1 compared athletic buoyancy to other cognate constructs, or similar constructs, to determine their conceptual boundaries. A one-time, online questionnaire was distributed to 294 recreational athletes (M age = 42 ...

Evaluation Of Repetitive Jumping Intensity On The Digi-Jump Machine, T. Scott Lyons, James W. Navalta, Whitley J. Stone, Mark A. Schafer, Laura Igaune May 2020

Evaluation Of Repetitive Jumping Intensity On The Digi-Jump Machine, T. Scott Lyons, James W. Navalta, Whitley J. Stone, Mark A. Schafer, Laura Igaune

International Journal of Exercise Science

Cardiorespiratory endurance is an important element of aerobic fitness, particularly in weight management and reducing risk for cardiovascular disease. While there are numerous options for aerobic exercise, rope jumping is often overlooked. In addition to regular exercise and a healthy diet, the American Heart Association strongly recommends rope jumping. The first purpose of this study was to determine the steady state metabolic cost of repetitive jumping on the Digi-Jump machine to evaluate whether exercise on this device is more or less strenuous than similar exercise with a jump rope, as demonstrated in previous literature. A second purpose was to determine ...


Cardiovascular And Stride Frequency Differences During Land And Aquatic Treadmill Walking, Jessica Burton, Sarah Duffey, Amber Hammonds, Anna Leduc, Rachel Shumate, John Coons, Ryan T. Conners May 2020

Cardiovascular And Stride Frequency Differences During Land And Aquatic Treadmill Walking, Jessica Burton, Sarah Duffey, Amber Hammonds, Anna Leduc, Rachel Shumate, John Coons, Ryan T. Conners

International Journal of Aquatic Research and Education

This study examined heart rate (HR) and stride frequency (SF) values of 30 college-aged males and females during dry-land (DL) and aquatic walking (AW). Aquatic walking trials were completed in an underwater treadmill with the water depth at waist level; the water temperature (31℃ ± 0.1℃) and room temperature (26.6℃ ± 0.1℃) were maintained at thermoneutral levels throughout the study. During each walking condition, HR and SF were recorded at treadmill speeds of 1 mph, 2 mph, and 3 mph. Participants were instructed to walk with their hands at their sides swinging as they would when walking on dry-land ...


The Impact Of The Covid-19 Crisis On Nebraska's Ethanol Industry, John C. Beghin, Sushant Timalsina May 2020

The Impact Of The Covid-19 Crisis On Nebraska's Ethanol Industry, John C. Beghin, Sushant Timalsina

Cornhusker Economics

This article looks at the impact of the pandemic crisis on Nebraska’s ethanol industry. We trace the changes in return margins since the last quarter of 2019 to early May of this year and show the deterioration of these margins and the resulting reduced returns, gross revenues and production reduction induced by the low returns.


Analysis And Exploration Of Novel Antibiotic-Producing Streptomyces Spp. In Spokane County, Washington, Kyle S. Kramer, Jenifer B. Walke Ph.D May 2020

Analysis And Exploration Of Novel Antibiotic-Producing Streptomyces Spp. In Spokane County, Washington, Kyle S. Kramer, Jenifer B. Walke Ph.D

2020 Symposium Posters

According to the Centers for Disease Control and Prevention, a US citizen is infected by an antibiotic-resistant pathogen every 11 seconds, and every 15 minutes, a patient dies as a result of these infections. Due to the increasing incidence of antibiotic-resistant pathogenic microbes, the study and exploration of novel antibiotics from novel environments are imperative as infectious diseases are the second leading cause of death in the United States. The purpose of this research is to investigate and analyze antibiotic-producing soil microbes in Spokane County, WA, with hopes of discovering novel antibiotic-producing microbes, specifically Streptomyces species, and explore some of ...
