Water droplet growth enhancement through thermal radiation
… how thermal radiation affects water droplet growth in the 20 to 100 μm size range. The theory of mass and energy transfer involving thermal radiation for a single droplet is presented. This theory is then extended to predict droplet growth for a given droplet distribution exposed to a …

Growth enhancement and selection attempts for Spirillum volutans
… colony counts and accurate quantification for growth or survival of Spirillum volutans; and to develop an improved method for selection of S. volutans from nature. Growth enhancement studies began with casein hydrolysate-succinate-salts medium (CHSS). Casein hydrolysate concentration, type of …

Burkholderia phytofirmans strain PsJN effects on drought resistance, physiological responses and growth of switchgrass
… management practices though applying plant growth promoting rhizobacteria (PGPR), of which our understanding is still rather limited. To elucidate physiological mechanisms behind PGPR's beneficial effects, we inoculated switchgrass seedlings with Burkholderia phytofirmans strain PsJN. Two …

The Company of Animals: a Nontoxic Approach.
… of each original print. In conclusion, areas for growth, enhancement, and future work are discussed, including a summary of the personal insights gained through the body of work. This thesis also supports the visual exhibition in the B. Carroll Reece Museum, East Tennessee State University, in …

Modeling and measurement of sodium chloride and ammonium sulfate droplet growth in laminar flow
Cloud droplet growth is governed by a balance between vapor diffusion, Kelvin effect, and Raoult’s law, as expressed in K¨ohler theory. In this study, a thermodynamic droplet growth framework initially developed by Brewster and Li (2021) for radiation-induced cooling of pure water droplets is …

Forest Net Primary Production Resistance Across a Gradient of Moderate Disturbance
… subcanopy enhanced leaf-level C uptake and the growth of this formerly light-limited canopy stratum, compensating for upper canopy production losses. As a result, whole-ecosystem production efficiency (ANPPw/LAI) increased at high levels of disturbance severity and leaf area loss. These findings …

Colon Cancer Initiation and Progression
… to identify suppressors of anchorage-independent growth by conducting a soft agar based shRNA screen within the cohort of CAN-genes. Remarkably, depletion of 65 of the 151 CAN-genes tested collaborated with ectopic expression of K-RASV12 and/or TP53 knockdown to promote anchorage-independent …

Arabidopsis thaliana P4-type ATPases ALA4 and ALA5 are Necessary for Normal Cellular Elongation in Developing Vegetative Tissues and Rescue the Pollen Tube Deficiencies in Knockout ala6/7 Mutants
… activities that are critical for normal growth and development of vegetative tissues. A double loss of function mutant for ala4/5 results in dwarfism for all vegetative tissues, including roots, leaves and hypocotyls. Selected cell types in these tissues were shown to be smaller. While a …

Synchrotron radiation-based characterization of GaN- based MQW structures and strongly correlated materials
… during the metalorganic vapor phase epitaxial growth. The relatively short diffusion length of group- III precursors and growth enhancement, due to facet migration was found to have significant effects on the MQW formation. The use of synchrotron based HRXRD and in particular cross-sectional …

Immunopathogenic mechanisms of non-healing cutaneous leishmaniasis caused by Leishmania amazonensis infection
… revealed that IFN-g alone could promote parasite growth within macrophages (MFs) by inducing the expression of mouse cationic amino acid transporter-2B (mCAT-2B), a key transporter for L-arginine. Although a clear upregulation of mCAT-2B and L-arginine transport was detected, no measurable iNOS or …

Effects of soil pH and soil water potential on arbuscular-mycorrhizal fungal colonization of soybean
… are highly affected by the conditions in the growth medium. The effect of extreme soil pH and moisture conditions on AM fungal development and plant-growth enhancement has been well documented independently. However, the soil factors that influence the survival and success of fungi may not act …

Tree Growth and Carbon Balance in a Temperate Forest Exposed to Elevated Carbon Dioxide for Eight Years
… dioxide Enrichment technology for 8 years. Growth was stimulated in the dominant canopy species in every year of the experiment with no evidence of a temporal decline in the response. Inter-annual variation in the growth response of P. taeda to elevated [CO2] was explained by the combination …

Molecular Characterization of Spinach (Spinacia Oleracea) Microbial Community Structure and its Interaction With Escherichia coli O157:H7 in Modified Atmosphere Conditions
… Bacteria isolated from fresh spinach elicited growth inhibition of E. coli O157:H7 in vitro, which was associated with nutrient competition. In contrast growth enhancement produced by epiphytes was associated to low correlations in carbon source utilization and the ability of E. coli O157:H7 to …

The effects of dung beetles on ecosystem functioning: From global trends to New Zealand pastures
… including dung removal, nutrient cycling, plant growth enhancement, bioturbation, secondary seed dispersal and trophic regulation. In a meta-analysis of the relationships between dung beetles and ecosystem functions and services (chapter two), I reveal significant positive relationships between …

Multigenerational effects of abnormal folate metabolism on embryo growth and development
… spectrum of developmental phenotypes including growth defects and congenital malformations. Remarkably, the Mtrrgt mouse line is a model of transgenerational epigenetic inheritance since the congenital malformations persist at least up to four wildtype generations after an Mtrr+/gt maternal …

Identification of a gene that makes-plants-gigantic-1: characterization of mpg1, a novel mutant of rice
… seed yield as well. Additionally, the extent of growth enhancement varied in the presence of stress, where this plant yielded higher biomass than wild-type plants under various stressors. This rice was more robust during optimal conditions, and even more so during stressed conditions compared to …
