An experiment was designed to determine the effects of a poured rubber flooring substrate on the behavior of captive Asian elephants. Additionally, room utilization was evaluated in a series of seven rooms used for indoor housing. These seven rooms were divided into two observation areas, the Front observation area which...
An investigation of the correlation between a number of behavioral,
morphological and physiological parameters and dominance status of male
Ring-necked Pheasants (Phasianus colchicus) was undertaken. Dominant
males performed significantly more aggressive behaviors than
subordinates and a higher proportion of these behaviors was directed
toward distantly ranked subordinates. Animals could also...
Plant hormones regulate progression through the different phases of plant development in response to endogenous and environmental cues. Gene expression studies, as well as genetic and molecular analysis of mutants with altered hormonal responses, are two common approaches to elucidate hormone response pathways. This dissertation compares ovary and fruit development...
This study is primarily concerned with the measurement of the local radiative component of total heat transfer around a horizontal tube immersed in a large particle fluidized bed at elevated temperatures.Total heat transfer was also measured in order to assess the relative radiation contribution.The radiation measurement probe employs a silicon...
Cephalopod-inspired soft robot arms have been studied as a new type of manipulator. These arms have been proposed for reach and grab tasks, underwater locomotion via swimming and walking, and robotic surgery. However, the capabilities of existing soft arms are limited to simple motions and light loads. Arm design has...
Background: The identification of the loci and specific alleles underlying variation in quantitative traits is an important goal for evolutionary biologists and breeders. Despite major advancements in genomics technology, moving from QTL to causal alleles remains a major challenge in genetics research. Near-isogenic lines are the ideal raw material for...
Benzylsuccinate (BSA), methylbenzylsuccinate (methylBSA), and ethylbenzylsuccinate (ethylBSA) are unambiguous anaerobic biotransformation products from toluene, xylenes, and ethylbenzene decay, respectively, and may be used to indicate intrinsic bioremediation is occurring at hydrocarbon-contaminated sites. In order to improve upon current methods that detect and quantify anaerobic hydrocarbon metabolites in field samples, solid-phase-extraction...
Fowl sperm are believed to be immotile prior to ejaculation. The concentration of
potassium found in deferent duct fluid is approximately 8 times higher than that found
in blood plasma, which is 5 mM in Gallus domesticus. The effect of ionic potassium
on fowl sperm motion was tested in a...
Genetic resistance is the most appropriate way to control diseases in crop plants. Resistance can be described as qualitative (involving a gene-for-gene system) or quantitative (with continuous distribution of disease levels). The relationships between different types of resistance remain obscure, as does the genetics of quantitative traits. The use of...
A primal formulation has been used to estimate a translog production function that includes fishing effort and fisherman’s skill as production factors. The selected functional form permits the analysis of the substitution possibilities among production inputs composing effort by calculating the Allen elasticity of substitution. Particular attention is paid to...
