Evaluating the suitability of the human toenail as a biomonitor for manganese status: the one source cohort
(University of Missouri--Columbia, 2007)
Numerous studies have demonstrated that the human toenail is a reliable biomonitor for the intake of Se and other elements. The objective of this study was to evaluate the hypothesis that Mn intake is reflected in toenail Mn levels. Interest...
Impacts of Precipitation, Land use Land cover and Soil type on the Water Balance of Lake Chad Basin
(2013)
Lake Chad Basin (LCB) has experienced drastic changes in land cover and poor water management practices during the last 50 years. The successive droughts in the 1970s and 1980s resulted in a decrease in surface water and groundwater resources...
Development and validation of standardized sampling protocols for assessing freshwater mussel populations in Missouri
(University of Missouri--Columbia, 2017)
.45 (Std. Err. = 0.05) across species, and varied greatly among taxa and the 3 rivers included in this study, and was influenced by temperature, discharge, and, to a lesser extent, by other factors. Correspondence of TVS and transects with excavation varied...
Experimental and theoretical studies of CO2 capture from air and of crystalline, ferroelectric, non-linear optical materials
(University of Missouri--Columbia, 2022)
approaches. In Chapter 1 to 3, we focused on a Rubisco inspired CO2 capture material, which is made of tetrapeptide KDDE. In chapter 1, we investigated the thermochemistry of the small amine system with full conformational space and determined the best method...
Three essays on the economics of pesticide use
(University of Missouri--Columbia, 2022)
, the adoption of organic pesticides in lawns and gardens is examined. A multinomial logit model is applied to analyze factors affecting adoption versus being in distinct non-adopter categories using a dataset from a survey of 661 residents in Missouri...
Hydrogen storage in pressed nanophase diamond powder
(University of Missouri--Columbia, 2010)
results in a net storage of 3.2 wt% with a recovery of 72% of the adsorbate at 750°C....
Resilience among elementary educators as measured by the personal and organizational quality assessment-revised and the emotional quotient inventory: short
(University of Missouri--Columbia, 2006)
Purpose: The purpose of this study was to examine the effect of time on the indices within the Personal and Organizational Assessment-Revised (POQA-R, Institute of HeartMath, 1999-2004) among rural, elementary educators ...
Enhancing bluegill production through least-cost diet development and novel rearing strategies
(University of Missouri--Columbia, 2010)
, the present study was carried out to (i) develop a least-cost diet for juvenile bluegill and (ii) determine the extent that the two novel rearing strategies, "topping off" and "size grading", would increase bluegill growth and production. The study developed a...
How financial decision-making changes when a marriage ends : evidence from the 1992-2016 health and retirement study
(University of Missouri--Columbia, 2019)
Transitioning from being married to divorced or widowed is difficult, financially as well as emotionally. Individuals who had left money matters to their partners during marriage enter a period of decreased financial control after marital...
Application of the systems approach : an information and decision model for the hog enterprise
(University of Missouri--Columbia, 1976)
. This is reported in Chapter Six. The practical use of the model for planning and control of the hog operation is described in Chapter Seven. A final chapter summarizes the approach, draws conclusions and makes suggestions for further research in this domain...
Evaluation of the bonus fishery created by the low-density stocking of Striped Bass (Morone saxatilis) in Bull Shoals Lake
(University of Missouri--Columbia, 2023)
Bull Shoals Lake is a large impoundment of the White River system in Missouri- Arkansas. Striped Bass (Morone saxatilis; STB) have been experimentally stocked into Bull Shoals since 2013 to create a low-density trophy fishery. We addressed...
Mechanisms of polar growth in the alphaproteobacterial order rhizobiales
(University of Missouri--Columbia, 2019)
characterized a comprehensive set of cell wall synthesis enzymes in A. tumefaciens and identified penicillin-binding protein 3a (PBP3a) and PBP3b as a synthetic lethal pair that function during cell division, and PBP1a as an essential enzyme required for polar...
