Nonlinear mechanics and testing of highly flexible one-dimensional structures using a camera-based motion analysis system
(University of Missouri--Columbia, 2006)
Both experimental and theoretical investigations are conducted for the dynamics of cables and strings. The exact equations of motion for finite but small amplitude vibration of string were derived based on a fully nonlinear ...
Mechanical and thermal weed control in organic crops
(University of Missouri--Columbia, 2017)
. This research was conducted in central Missouri from 2016-2017 to compare cultivation, flame application, between-row mowing, and hot water spray for in-season weed control in organic corn and soybeans. Between-row mowing and hot water application were paired...
Effects of forest fragmentation on reproductive effort and productivity of Indigo buntings (Passerina cyanea)
(University of Missouri--Columbia, 2005)
and offspring quality, I measured maternal condition and reproductive output of Indigo Buntings breeding in a fragmented and a contiguously forested landscape in Missouri. Renesting females had lower body condition than those that nested once successfully...
Unelected oversight : the politics of government investigations and problem monitoring
(University of Missouri--Columbia, 2020)
How do elected officials and top decisionmakers receive information about the problems encountered in government agencies? Policymaking and agenda setting research primarily examines how elected officials directly gather ...
Maladaptation of cardiac and skeletal muscle in chronic disease : effects of exercise
(University of Missouri--Columbia, 2007)
The human genome is adapted for daily physical activity (85). Thus, a sedentary lifestyle is capable of promoting detrimental consequences to human health. The linkage between lack of sufficient physical activity and the ...
The effect of gene therapy on the pathogenesis of amyotrophic lateral sclerosis (ALS)
(University of Missouri--Columbia, 2021)
Amyotrophic lateral sclerosis (ALS) is a devastating progressive and neurodegenerative disease. In early stages of ALS, there are known pathological changes in the structure of neuromuscular junctions (NMJ); however, all ...
Impacts of suspended and deposited sediment on benthic invertebrates and fishes in a Missouri Ozark stream
(University of Missouri--Columbia, 2006)
Sediment is suspected in the decline of sensitive-aquatic organisms in the Osage River basin of Missouri. In this study, I monitored sediment dynamics and evaluated corresponding linkages with benthic invertebrate and fish assemblages as it related...
Impacts of municipal wastewater effluent on seed banks, chemistry, and microorganisms of soils excavated from wetland impoundments designated for wildlife
(University of Missouri--Columbia, 2009)
To evaluate the effects of municipal wastewater effluent (WWE) and Missouri River water (MOR) as irrigation sources on soil chemistry, seed banks, and microorganisms, a field study was conducted in conjunction with a set of greenhouse studies...
Establishing mostly-male bluegill groups and evaluating their growth benefits in indoor rearing systems
(University of Missouri--Columbia, 2007)
Male bluegill have the greatest potential to reach food market size ([greater than or equal to] 0.5 lb.; 225g) within two growing seasons. However, establishment of monosex, juvenile bluegill groups does not currently ...
Three essays on monetary and financial economics
(University of Missouri--Columbia, 2018)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] This three-chapter dissertation focuses on the research topics in Monetary and Financial Economics. The first paper examines the time-varying impact of U.S. monetary policy...
Characterization of soybean rooting depth in response to different environmental conditions
(University of Missouri--Columbia, 2020)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI-COLUMBIA AT REQUEST OF AUTHOR.] Soybean (Glycine max (L.) is currently grown throughout the world because it has been adapted to many environments and because of the high protein and oil content...
Inertial electrostatic confinement: theoretical and experimental studies of spherical devices
(University of Missouri--Columbia, 2007)
Inertial Electrostatic Confinement (IEC) is a means to confine ions for fusion purposes with electrostatic fields in a converging geometry. Its engineering simplicity makes it appealing when compared to magnetic confinement ...
FDI and economic growth : the role of stock market liberalization and trade liberalization
(University of Missouri--Columbia, 2008)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] This paper analyzes the effect of stock market liberalization and trade liberalization on the relationship between FDI and economic growth using the data of 124 countries...
Quantifying neonicotinoid concentrations in Missouri wetlands, their driving factors, and the potential effects on the reliant avian community
(University of Missouri--Columbia, 2018)
been proposed as indicator taxa as they are reliant on insect food reserves and have recently experienced population declines. Thus, we developed two studies in floodplain wetlands to quantify neonicotinoids in Missouri wetlands and potential effects...
Alcohol consumption, executive function and risky decision making
(University of Missouri--Columbia, 2009)
Previous research has shown that alcohol intoxication can adversely affect behavior by impairing higher cognitive function (e.g., Giancola, 2000) and can lead to increased risk-taking (Leigh, 1999) via impaired executive ...
The effects of metal contamination on larval white sturgeon in the upper Columbia River
(University of Missouri--Columbia, 2018)
how metals affect larval sturgeon behavior and survival. Of particular concern are reported field observations of large numbers of sturgeon larvae with empty guts at a critical point in their life cycle. By putting all these pieces together, I found...
Economic analysis of woody biomass harvesting in the Missouri Ozarks
(University of Missouri--Columbia, 2010)
An integrated mechanized timber harvest thinning treatment to remove small diameter trees and merchantable saw logs was conducted on 30 acres of the Missouri, Ozarks in the summer of 2009. Two silvicultural treatments (single tree selection...
Use of main channel and shallow-water habitat by larval fishes in the lower Missouri River
(University of Missouri--Columbia, 2006)
I developed a series of research objectives organized in a spatial hierarchy to characterize larval fish nursery habitat within the lower Missouri River. Native carpsucker spp./buffalo spp. (Carpiodes spp./Ictiobus spp.) and chub spp. (Macrhybopsis...
