(University of Missouri--Columbia, 2021)
, lung cancer, and other major diseases. Smoke from active smokers has been extensively investigated by a number of researchers. These studies have examined methods for the analysis of nicotine and its metabolites. In contrast, the development of methods...
Food insecurity and foraging food from gardening, hunting, and fishing among supplemental nutrition assistance program and eligible supplemental nutrition assistance program families
(University of Missouri--Columbia, 2020)
Households participating in, or eligible for, USDA's Supplemental Nutrition Assistance Program (SNAP) deploy many food acquisition strategies to enhance their food security because the SNAP program is intended to supplement rather than provide all a...
Dynamic analysis of complex panel count data
(University of Missouri--Columbia, 2021)
approach, an extensive simulation study is conducted and suggests that it works well in practical situations. An application to the China Health and Nutrition Survey (CHNS) study is provided. In practice, there could exist more than one type of event...
Three essays on phosphorus runoff and water quality
(University of Missouri--Columbia, 2019)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Water pollution caused by nutrients, and the resulting eutrophication, have increased over time. This water pollution is increasingly caused by non-point source pollution, both...

(University of Missouri--Columbia, 2018)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Untargeted metabolite profiling of switchgrass using cloud metabolomics platform. Integrated biorefining incorporates biomass conversion processes and equipment to produce...
Growing Missouri’s aquaculture industry : marketing study
(University of Missouri--Columbia. Extension Division, 2023)
dollars from 2013 to 2018, but the growth did not keep up with inflation. Missouri generated 3% of all U.S. bait fish sales. In no other aquaculture category did the state achieve a market share this high. However, food fish more heavily contributed...
Genetic and nutritional effects on reproduction in lactating dairy cows
(University of Missouri--Columbia, 2020)
background but are influenced by maternal nutrition. Study four investigated the association between milk PAG S-N in early gestation with variables related to the dam, sire and gestating fetus. Dam genetic merit for milk production did not have a large effect...
Sleep intraindividual variability and fatigue in parents of children on the autism spectrum
(University of Missouri--Columbia, 2022)
Fatigue is associated with numerous harmful physical and mental health outcomes. Despite the established relationship between sleep and fatigue, research on the association between the variability of sleep measures within ...
The influence of body mass and body composition on bone functional adaptation
(University of Missouri--Columbia, 2023)
The proposed dissertation follows a three article format. The articles are distinct, but each pertains to the same subject of research. The first article applies structural equation modeling to factors influencing bone ...
Evaluating and improving corn nitrogen fertilizer recommendation tools across the U.S. Midwest
(University of Missouri--Columbia, 2018)
Determining which corn (Zea mays L.) nitrogen (N) recommendation tools best predict the economically optimal N rate (EONR) would be valuable for maximizing profits and minimizing environmental consequences. The objectives of this research were...
