Drivers of Soil Fungal Communities Across Three Tropical Rainforests in Panama

Creator:: Schappe, Tyler
Abstract:: Fungi play critical roles in ecosystem processes and interact with plant communities in mutualistic, pathogenic, and commensal ways. Fungal communities are thought to be influenced by both associated tree communities and soil properties. However, the relative importance of the biotic and abiotic drivers of soil fungal community structure and diversity...

Hydrogen-stimulated CO₂ fixation and coordinate derepression of hydrogenase and ribulosebisphosphate carboxylase in a H₂-uptake positive strain of Rhizobium japonicum

Creator:: Simpson, Frank Berry
Abstract:: H₂-uptake positive strains (122 DES and SR) and H₂-uptake negative strains SR2 and SR3 of Rhizobium japonicum were examined for ribulosebisphosphate (RuBP) carboxylase and H₂-uptake activities during growth conditions which induced formation of the hydrogenase system. The rate of ¹⁴CO₂ uptake by hydrogenase-induced cells was about six times greater in...

Cytophotometric determinations of nuclear DNA content in tissues of the wax moth larva, Galleria mellonella Linnaeus

Creator:: Longo, Frank J., 1939-
Abstract:: The present study was undertaken to determine, by measurement of nuclear DNA, the degrees and frequencies of ploidy in the last larval instar of the moth Galleria mellonella Linnaeus. While such data have been amassed for a wide variety of vertebrate tissues, few studies have been concerned with invertebrates and...

The Genomic Capabilities of Microbial Communities Track Seasonal Variation in Arctic Lagoons

Creator:: Baker, Kristina D.
Abstract:: The lagoons spanning Alaska’s Beaufort Sea coast provide a unique habitat for arctic wildlife. These lagoons and the food webs they support face extreme seasonality with nine months of ice cover followed by a spring thaw that pulses a large amount of freshwater and nutrients into the lagoons. Bacteria link...

Using Magnetotellurics Towards Imaging the Primary Magma Reservoir in the Cotopaxi Volcano, Ecuador

Creator:: Angel, Kaitlan W. E.
Abstract:: In this study, 3D finite difference and 2D finite element forward modeling were used to create an electromagnetic sensitivity analysis for the Cotopaxi volcano in Ecuador. Magnetotellurics (MT) is a natural-source electromagnetic geophysical technique that images electrical conductivity. Measuring strong contrasts in electrical conductivity in volcanic materials allows for the...

The effect of catalyst properties on the synthesis of carbon nanotubes by plasma enhanced chemical vapor deposition

Creator:: Cheemalapati, Surya Venkata Sekhar
Abstract:: A study of the effect of catalyst properties on the synthesis of carbon nanotubes (CNTs) is done in this thesis. Three different metal alloy catalysts, Fe/Ti, Ni/Ti, Co/Ti, have been studied. Various atomic concentrations and thicknesses were cosputter deposited on clean Si wafers using AJA Orion 4 RF Magnetron sputter...

Tracer experiments in a non-uniform porous medium : implications of diffusive mass transfer on the late-time breakthrough behavior

Creator:: Freiherr von Schwerin, Claudius
Abstract:: Mass transfer processes were evaluated in an artificial, non-uniform porous medium with a power law distribution of diffusion rate coefficients obtained from physical characterization of solute and porous medium. Breakthrough curves of several pulse experiments conducted at different velocities were compared (1) to analytical expressions for concentrations at mass transfer...

The Influence of Hip Abduction, Extension, and External Rotation Rate of Torque Development on Frontal-Plane Biomechanics during Single-Leg Jump-Cuts

Creator:: Cronin, Baker
Abstract:: Anterior cruciate ligament injuries are relatively common in female athletes with greater frontal plane knee motion and loading during a landing task predictive of injury. As a result, decreasing knee abduction motion and loading is important for ACL injury prevention. While increased strength of the hip abductors, extensors, and external...

A comparative study of apparel shopping orientations between Asian Americans and Caucasian Americans

Creator:: Ho, Shan-hsin Angie
Abstract:: Very little empirical research has been conducted on Asian Americans as a whole in relation to their consumer behavior, specifically their clothing behavior. A review of literature demonstrated that Asian Americans have been studied from different psychographic and sociological aspects. However, the apparel shopping behavior of this market has received...

The Effect of Exercise on the Biomechanical Determinants of Knee Energy Absorption during Single-leg Jump-cuts

Creator:: Pollard, Anne E.
Abstract:: Anterior cruciate ligament injuries are common in a wide variety of sports and most frequently occur during activities requiring rapid deceleration such as landing and cutting. Deceleration of the body's center of mass during movement results primarily from eccentric muscle contraction. This type of contraction serves to absorb energy from...
