The sublethal effects of methoxyfenozide on the field orientation and courtship behavior of Cydia pomonella (Linnaeus) (Lepidoptera: tortricidae)
(University of Missouri--Columbia, 2008)
The sublethal effects of ecdysone agonist methoxyfenozide on the mating behavior and field orientation of codling moth, Cydia pomonella (Linnaeus), was examined. Five different lure types were placed in the upper canopy of 25 apple trees in a 5-acre...
Microbiological and electrophoretic studies of the binding of antibiotics by milk and milk components
(University of Missouri--Columbia, 1970)
. If this fails, the susceptibility of the host and the virulence of the causative agent will determine the severity of ensuing mastitis. The presence of the pathogen in the gland and the host’s reaction make the development of mastitis a very dynamic process...
Local free convection to non-Newtonian fluids from a horizontal, isothermal cylinder
(University of Missouri--Columbia, 1972)
The transfer of heat between a body surface and the motionless fluid surrounding it is perhaps one of the most naturally occurring physical phenomena. Undoubtedly interest and speculation regarding this natural or free convection behavior dates back...
Rural southern residents and the incentive to work
(University of Missouri--Columbia, 1972)
"There has been much interest in the past few years in welfare reform. This interest is a result of the rising criticisms of the many relief measures which comprise the welfare, or public assistance, program. Two of these criticisms are that public...
Three essays on dividend and payout policy
(University of Missouri--Columbia, 2007)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] This dissertation contains 3 essays on dividend/payout policy. In the first essay, using a sample of 76,129 firm-years from 32 countries, I show that both the probability...
Interactions of formamidines with the platelet serotonin uptake system
(University of Missouri--Columbia, 1981)
chlordimeform inhibited the uptake of 5-HT by rat blood platelets, 2. To determine the relationship between formamidine structure and 5-HT uptake inhibitory potency, 3. To study the mechanism by which formamidines inhibit 5-HT uptake using chlordimeform as a...
Approaches for comparing the structural characteristics of different representations of transportation systems
(University of Missouri--Columbia, 2018)
comparing Net B to Net A (i.e., most of records are within 10m distance). Comparing the computed distance between Net A path vertices and the assigned arcs in Net C shows that 99.2% of the records are within 10m, and only 0.8% of the arcs have a greater...
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...
Effects of temperature, photoperiod, and substrate on the maturation and reproductive behavior of the Topeka shiner (Notropis topeka)
(University of Missouri--Columbia, 2008)
The Topeka shiner (Notropis topeka) is a federally-listed endangered cyprinid species native to small headwater prairie streams in the mid-west of the United States. It generally spawns over and around sunfish (Lepomis sp.) nests. The objectives...
A study of parametric instability of eccentrically stiffened rectangular plates
(University of Missouri--Columbia, 1974)
-dependent ordinary differential equations, were then expressed in matrix notation. The solution of the resulting matrix equation, which was assumed in the form of a Fourier series, showed that the boundary of the regions of parametric instability could be determined...
Entrainment and transport of coarse stream bed material in a fluviokarst watershed, south-central Missouri : a tracer particle study
(University of Missouri--Columbia, 2010)
of the longitudinal movement of tracers over a 10-month period indicate that minor amounts (0-13.2%) of coarse bed material in TCC are mobilized by relatively low flows (5-28% of bankfull) that recur somewhat frequently (less than 3.1 years). BCH transports a higher...
Implementation of integrated mathematics textbooks in secondary school classrooms
(University of Missouri--Columbia, 2009)
The study reports how 44 secondary school teachers implemented the first two courses of an integrated mathematics textbook series, Core-Plus. Textbook implementation was examined in relation to three components: (a) regular use of textbook; (b) use...
Numerical solutions to the Poisson equation in media surrounding multiple arbitrarily shaped bodies
(University of Missouri--Columbia, 2010)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] The dissertation describes a general, efficient, and parallelized approach to solving the Poisson equation in the volume surrounding multiple, arbitrarily shaped bodies. Green...
Investigations of Mississippi valley-type mineralizing fluids via analytical geochemistry, numerical modeling, and experimental geochemistry
(University of Missouri--Columbia, 2021)
-stage mineral in MVT deposits, thus it has a high potential for this purpose. However, experimental distribution coefficients (D) for the partitioning of Zn between dolomite and aqueous solution are unknown. A series of dolomite precipitation experiments...
Evolution of environmental news and the 'coconut wireless' : a study of the communication methods and strategies of environmental nonprofits on Kau'i
(University of Missouri--Columbia, 2019)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI--COLUMBIA AT REQUEST OF AUTHOR.] Catastrophic environmental news bombards us on a regular basis, yet, issues from human impact persist. Despite the number of environmental nonprofits working toward...
Investor capital, taxes and the structure of cattle feeding
(University of Missouri--Columbia, 1974)
,000 head size have increased in numbers at a rapid rate in recent years. However, multi-lot cattle feeding firms have lots of widely varying sizes and in widely scattered locations. This pattern suggests considerations beyond production economies of size...
A methodology for shortage area designation of physicians : selected applications
(University of Missouri-Columbia., 1975)
An analysis of farm type classification systems
(University of Missouri--Columbia, 1971)
. Complications exist when comparability is attempted among university criteria, Census c rite ria and U.S.D.A. programs such as "Costs and Returns on Commercial Farms". "Costs and Returns on Commercial Farms" are not actual farms but are farms constructed from...
Conservation of Sooty Terns on Wake Atoll complex
(University of Missouri--Columbia, 2011)
the past two decades. However, the danger of non-target poisoning to seabirds has rarely been examined. In a second study, I assessed the risk of rodenticide bait to nesting Sooty Terns using placebo bait. I found no evidence of pellet ingestion based...
Essays on money and banking: a search-theoretic approach
(University of Missouri--Columbia, 2022)
periods. The quantitative analysis suggests that the dramatic changes in the money multiplier after 2008 were driven by the introduction of interest on reserves with a low nominal interest rate. In the second chapter, I develop a dynamic general...
