Establishing a foundation for large DNA transfer to artificial minichromosomes and B insert platforms in maize
(University of Missouri--Columbia, 2019)
In plants, conventional genetic engineering methods limit the number of available traits that could potentially improve the quality of agriculture. Agrobacterium-mediated transformation and biolistic bombardment are tools used in transferring genes...
Development and evaluation of a site stormwater analysis calculator intended for the State of Missouri utilzing regional best management practices
(University of Missouri--Columbia, 2023)
The Site Stormwater with Best Management Practices (BMPs) Analysis Calculator was created to be utilized in the State of Missouri for developing or re- developing property. Simplistic and conservative stormwater evaluations utilizing regional...
Associations between psychosis risk and emotional distress disorders with cortical surface morphometry
(University of Missouri--Columbia, 2020)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI-COLUMBIA AT REQUEST OF AUTHOR.] Neuroimaging studies have consistently found structural cortical abnormalities in schizophrenia, especially in structural hubs. However, it is unclear what...
Cytogenetic analysis of a knobbed chromosome 9 in maize
(University of Missouri--Columbia, 1971)
* knob did not influence the zig-zag effect on recombination induced by the odd-even number of B-chromosomes. Previous preferential segregation studies have indicated that it is the genes linked to the larger of the twoknobs of chromosome 9 bivalents...
Flow and heat transfer properties of Mono Craters rhyolites : effects of temperature, water content, and crystallinity
(University of Missouri--Columbia, 2008)
and concentric cylinder methods to obtain viscosity measurements between 5 x 103̂ to 8 x 101̂2 Pas, from superliquidus conditions to the glass transition; the laser flash (LFA) method to measure thermal diffusivity of samples between room and subliquidus...
Influence of site conditions on near-field effects in multi-channel surface wave measurements
(University of Missouri--Columbia, 2011)
using multi-channel arrays. A recent criteria developed by Yoon and Rix (2009) for multi-channel measurements suggested that the normalized array center (NAC) distance (i.e. the number of wavelengths between the source and array center) should be 2...
Use of main channel and shallow-water habitat by larval fishes in the lower Missouri River
(University of Missouri--Columbia, 2006)
or equal to] 5 cm/s. Silver/bighead carp (Hypophthalmichthys molitrix/nobilus) exhibited no selection based on water depth or current velocity. Chub spp. selected depths between 20-50 cm and areas 2-3 m from the waters edge. The larval fish assemblage...
The most favorable temperatures for the cooking of some typical foods
(University of Missouri--Columbia, 1915)
A search through available published material on the subject of the cooking of foods reveals for the most part only recommendations of fairly wide ranges rather than definite limits of temperature for the cooking of specified ...
Comparing the diversity, geographic distribution, and intraspecific variation of subterranean termites (Reticulitermes: Isoptera: Rhinotermitidae) occuring in woodlands and urban environments of Missouri using morphology and 16s mtDNA
(University of Missouri--Columbia, 2007)
. In urban environments they feed upon dead wood, and therefore infest and destroy man-made wooden structures. Missouri is considered to have a moderate risk for termite infestations when compared with the states of the southeast part of the country. Despite...
Effect of plagioclase crystallization on liquid and magma viscosity in the Anorthite-diopside-dorsterite-quartz system
(University of Missouri--Columbia, 2006)
SiO2 (CMAS) glasses were synthesized as analogs for dacitic and basaltic lavas. Liquid viscosities were measured between 101 and 1013 Pa s, over the temperature range of approximately 1600 to 700⁰C, using concentric cylinder and parallel plate...
Point processes on the complex plane with applications
(University of Missouri--Columbia, 2019)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] A point process is a random collection of points from a certain space, and point process models are widely used in areas dealing with spatial data. However, studies of point...
Stochastic forms of functional isoperimetric inequalities
(University of Missouri--Columbia, 2021)
significance. On the other hand, it was recently shown that the Brunn-Minkowski inequality, specialized to convex sets, follows from a local stochastic dominance for naturally associated random polytopes. In addition, a number of other geometric inequalities...
Factors influencing income and production efficiency on Missouri dairy farms, 1955 and 1956
(University of Missouri., 1958)
"The purpose of this project is to study the competitive position of Missouri dairy farms using business records of dairy farmers in order to determine the cost of producing milk on farms of different sizes (economic of scale), and the relationship...
Modeling the financial impact of management decisions on loblolly pine (Pinus taeda) production
(University of Missouri--Columbia, 2010)
Located primarily in the southeastern United States, Loblolly pine (Pinus taeda L.) is a variety of Southern yellow pine that is often planted by non-industrial private landowners seeking a beneficial long-term investment ...
Milk supply response in Greater Kansas City marketing area
(University of Missouri--Columbia, 1964)
The growth of the dairy industry has been an important factor in the agricultural development of the United States. Missouri has shared in this development. The sale of dairy products has contributed nine to thirteen percent of the total income from...
Coprolites of the late eocene using virtual paleontology from the Pipestone Springs Main Pocket, Montana
(University of Missouri--Columbia, 2022)
volumes and diameters for statistical comparison between the two different size classes of coprolite. In combination with volume renders of the segmented material, we also adopt more traditional methods such as thin-section petrography and scanning...
Photoacoustic detection of circulating tumor cells
(University of Missouri--Columbia, 2013)
based on the change in refractive index was developed to detect individual melanoma cells. The sensitivity of the optical based detector was high and has the resolution to determine the presence of extremely low number of metastatic and cultured cells (2...
Chemical modifications to produce soy-based polyols
(University of Missouri--Columbia, 2009)
at temperatures near 150 °C using p-toluenesulfonic acid to promote the reaction. In the first part of the study, different temperatures and reaction times were evaluated to optimize the reaction. In the second part of the study, different mole ratios of ethylene...
