Tensile strength, shear strength, and effective stress for unsaturated sand
(University of Missouri--Columbia, 2006)
It is generally accepted in geotechnical engineering that non-cohesive materials such as sands exhibit no or negligible tensile strength. However, there is significant evidence that interparticle forces arising from capillary ...
Centromere function and evolution in maize (Zea mays)
(University of Missouri--Columbia, 2006)
A dispensable supernumerary chromosome present in maize, the B chromosome, was the focus of many centromere studies. First, I examine the variation in copy number of centromeric elements and other repeats among different ...
Uterine regulation of preimplantation embryo development in fertility-classified heifers
(University of Missouri--Columbia, 2018)
, serial embryo transfer (3-4 rounds) was used to classify heifers based on pregnancy success on day 28 as high fertile (HF; 100%), subfertile (SF; 25%), or infertile (IF; 0%). Next, a series of experiments were conducted using the fertility...
Genomics of seasonal hair shedding and ecoregion-specific growth to identify environmentally-adapted beef cattle
(University of Missouri--Columbia, 2020)
Recently, interest has increased in augmenting current national scale cattle evaluations with precision genetic predictions tailored to specific environmental conditions. Some efforts to develop environmentally-aware ...
Theoretical analysis of heat and mass transfer processes in an evaporative cooling system with zeolite desiccant powered by solar energy
(University of Missouri--Columbia, 2018)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Concerns about energy sources depletion and environmental pollution issues have been raised and is a top priority of the global community. Refrigeration machines have been...
Seasonality and elevational migration in an Andean bird community
(University of Missouri--Columbia, 2010)
Life history strategies of many birds in the Neotropics remain poorly known. In particular, details on the seasonal movements of individuals and populations within the Neotropics remain largely unknown, including short-distance ...
Hydrodynamic characteristics and capillary-assisted heat transfer enhancement of non-condensing/condensing two-phase flows
(University of Missouri--Columbia, 2020)
Interfacial characteristics of two-phase flows were studied through visualization experiments and numerical simulation using computational fluid dynamics (CFD) based on the volume-of-fluid (VOF)-continuum surface force (CSF) method...
Consequences of plant water limitation for aphids, their natural enemies, and insect communities
(University of Missouri--Columbia, 2020)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Climate change is causing an increase in drought events around the world. Water limitation affects the quality and quantity of plant resources for herbivorous insects, resulting...
Exploring elementary student energy literacy outcomes in the outdoor classroom : a comparative study
(University of Missouri--Columbia, 2020)
Environmental issues such as global warming, air and water pollution, and excessive consumption of fossil fuels are the challenging problems that endanger the future of our planet and, consequently, humankind. These problems ...
Authoritarian successor parties and political protest in Asia
(University of Missouri--Columbia, 2020)
How does an authoritarian successor party (ASP) interact with civil society in East and Southeast Asia? Does an ASP's control over the executive and legislature increase or decrease protest movements? Do ASPs effectively ...
Amphibian metamorphosis and juvenile terrestrial performance following chronic cadmium exposure in the aquatic environment
(University of Missouri--Columbia, 2005)
degradation and amphibian declines. Manipulative experiments were conducted to investigate the performance (i.e., growth, survival) of amphibians that metamorphose from chemically-contaminated aquatic breeding sites. The heavy metal cadmium (Cd) was selected...
Bathing on the edge of empire : local variation and regional adaptation in the late Roman military bathhouses of Arabia/Palaestina
(University of Missouri--Columbia, 2020)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI--COLUMBIA AT REQUEST OF AUTHOR.] This dissertation examines the evidence for Roman military baths in the provinces of Arabia and Syria Palaestina dating from the late 2nd-5th c. C.E., and their place...
Agent-based modeling of seasonal population movement and the spread of the 1918-1919 flu: the effect on a small community
(University of Missouri--Columbia, 2004)
Agent-based modeling provides a new approach to the study of virgin soil epidemics like the 1918-1919 flu. By using this bottom-up simulation approach, a landscape can be created and populated with a heterogeneous group ...
Great Lakes lake trout early mortality syndrome (EMS) : contaminants, thiamin status, and their possible interaction
(University of Missouri--Columbia, 2006)
Salmonid populations in the Great Lakes experienced a decline in the early twentieth century, presumably due to over-fishing combined with the introduction of exotic parasites such as the sea lamprey. Despite intensive ...
Investigation of the initial steps of jasmonic acid biosynthesis and a study of differential regulation of the ribosomal association of mRNA transcripts in jasmonate-dependent wound response
(University of Missouri--Columbia, 2020)
expression alone, implied a post-translational regulatory mechanism. Experiments with a truncated version of NbGLA1 showed that the C-terminal end may contain sequence elements that can function in a regulatory role. Finally, JA accumulation time course...
Crying in the wilderness : the outlaw and poet in Ben Hecht's militant Zionism
(University of Missouri--Columbia, 2013)
that he developed as a crime reporter covering gangland Chicago and the rise of Al Capone. At the same time, his propaganda can be understood as the cultural rebellion of a modernist artist, who was chafing against rules imposed by the "respectable...
