Nutrients, chlorophyll and bacterial fecal indicators in coves and open water areas of Lake of the Ozarks, Missouri
(University of Missouri--Columbia, 2009)
Urban development and use of septic tanks in porous soils of Lake of the Ozarks poses a threat to public health via leaching into drinking wells and coves used for swimming. During 2 summers, phosphorus (TP), nitrogen (TN), chlorophyll (Chl), fecal...
An ecological systems approach to reduce children's encounters with obscenity on the internet
(University of Missouri--Columbia, 2007)
Ecological Systems Model to solve the problem of children's encounters with online obscenity. The ecological systems perspective is a framework for recommendations and solutions. When each environmental system from the model collaborate in effort toward a...
Computational studies of three chemical systems
(University of Missouri--Columbia, 2011)
are examined to better understand the process by which self-assembly of the nanocapsule occurs. The second topic is the study of the addition of H2O and O2 to vanadyl complexes of the form [VOX(NCCH3)]+ where X = F-, Cl-, Br-, I-, and OH-. Changing the identity...
Pre-harvest water quality of ephemeral streams in Missouri Ozark forests
(University of Missouri--Columbia, 2006)
baseline values were established: pH was 8.3, electrical conductivity was 200 us/cm, TSS was 0.5 g/L and TVSS was 0.2 g/L, Ca was 13 mg/L and Mg was 10 mg/L, K was 10 mg/L, TP was 1.3 mg/L and SRP was 1.1 mg/L, total nitrogen was 5.8 mg/L and nitrate...
Design and synthesis of group 8 transition metal complexes for C-C bond forming valorization of carbon dioxide
(University of Missouri--Columbia, 2023)
development studies have focused on the transformation of CO2 into C1 products, such as carbon monoxide or methanol, the reductive coupling of CO2 to produce new C-C bonds is an emerging field that has the potential to produce valuable commodities in a...
Molecular mechanism, binding free energy, and sequence selectivity of intercalation of doxorubicin and DNA
(2021)
selectivity depends mainly on the base pairs located downstream from the DOX intercalation site, with a preference for (AT)2 or (TA)2 driven by the favorable electrostatic and/or van der Waals interactions. Invoking the quartet sequence model proved to be most...
Pottery production at Fort Hill (27CH85) a seventeenth-century refugee community in northern New England
(University of Missouri--Columbia, 2009)
by well over half within less than 100 years. Individuals and families responded to the rapid social change of this time by fleeing high-stress areas and joining communities perceived to be more stable. A model for detecting this refugee movement...
Modification of fatty acid composition in soybean seeds to improve soybean oil quality and functionality
(University of Missouri--Columbia, 2011)
acid content. Combination of two mutant FAD2-1A and FAD2-1B with mutant FAD3A or mutant FAD3C or both resulted in high oleic acid content of 80 - 85% and linolenic acid content in the range from 1.5 - 4%. Perfect molecular markers associated...
Nitrosative guanosine deamination : pyrimidine ring opening implications of effects in homogeneous solution as well as anisotropic environments
(University of Missouri--Columbia, 2007)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] In recent years a great deal of interest has been focused on the exposure to nitrous acid (HNO2), nitric oxide (NO) and other nitrosating species because they are mutagenic...
Clustering in relational data and ontologies
(University of Missouri--Columbia, 2010)
This dissertation studies the problem of clustering objects represented by relational data. This is a pertinent problem as many real-world data sets can only be represented by relational data for which object-based clustering algorithms...
Meretites' Faience Ushebtis: An Analysis and Determination of their Production in a Late Period or Ptolemaic Workshop
(2010)
The hundreds of faience shabtis in an individual Late Period burial demanded a significant production effort within a workshop. Petrie's discovery of thousands of molds for small faience objects in Amarna (1891-92) and Memphis (1908-13) led...
Older childless adults' inter-vivos transfers of emotional, instrumental, and financial support and predictors of giving to kin and non-kin
(University of Missouri--Columbia, 2008)
Inter-vivos transfers, or support given to others during a person's lifetime, are vital to the economy, public resource preservation, and social policies. The increasing prevalence of childlessness among older adults and their often ample resources...
A Hybrid Modeling Approach to Assess the Efficacy of Control Measures on Paratuberculosis on U.S. Dairy Farms
(University of Missouri--Kansas City, 2016)
Paratuberculosis, also known as Johne's disease or JD, is a chronic contagious
infection, caused by Mycobaterium avium paratuberculosis (MAP). This fatal disease
is incurable and causes considerable economic losses to ...
Multi-scale self-assembly of nanoenergetic materials utilizing functionalized graphene
(University of Missouri--Columbia, 2020)
GO, forming a 3D structure with high porosity, controllable density, size, shape and chemical composition. The phase separation between Al and Bi2O3 was minimized, and the energetic reactivity of both nanoparticles was retained. Therefore, the final product r...
Wealth accumulation differences between wage-earning and entrepreneurial families : the role of active saving behavior
(University of Missouri--Columbia, 2008)
This study examines the causal relationship between entrepreneurship and wealth accumulation. Saving behavior is a potential source of family wealth differentials. It is proposed that entrepreneurial families exhibit more accelerated active saving...
Rhizobacteria associated with glyphosate-resistant soybean (Glycine Max)
(University of Missouri--Columbia, 2006)
activity to a limited extent, possibly due to reduced levels of root exudates caused by the treatments. Inhibition of ivyleaf morningglory seedling growth by Bradyrhizobium japonicum isolate GD3 was greater than IAA alone. Certain rhizobacteria...
Perceived Economic Pressures and Farmer Ethics
(2008)
not experiencing economic pressures. To test this hypothesis, we use data from a survey of 3,000 Missouri farmers with farm sales in excess of $10,000 in 2005 in which farmers were asked how acceptable they considered various unethical or questionable farming...
Reliability-based analysis of settlements of shallow foundations on cohesionless soils
(University of Missouri--Columbia, 2020)
, and consequently to the settlement estimations. Traditional settlement analysis methodologies do not incorporate a consistent approach to account for the uncertainties and can lead to either costly design by overestimation of the settlement or a risky design...
Instrumentation and early performance of an innovative prestressed precast pavement system
(University of Missouri--Columbia, 2006)
