The Geology of the Graveston Quadrangle, Union and Knox Counties, Tennessee

This thesis, entitled The Geology of the Graveston Quadrangle, Union and Knox Counties, Tennessee is one in a series being undertaken by graduate students in the Department of Geology and Geography, University of Tennessee. The area under study had been mapped previously by Arthur Keith (U.S.G.S. Maynardville folio, no. 75, 1901) on a scale of 1:125,000. The geologic mapping by the present writer was done on the Tennessee Valley Authority base map (Graveston Quadrangle, 164-NE) which has a scale of 1:24,000. The reconnaissance field work was undertaken in the fall of 1948 using the Maynardville folio for purpose of general information. Field work was delayed during the late winter and early spring months due to inclement weather conditions. During late spring and early summer the field work was renewed and subsequently completed in July, 1949

Becoming a mystic: an analysis of developmental factors according to the Murray "Need-Press" theory

Thesis (Ph.D.)--Boston UniversityThis study investigated the early lives of certain mystics from a psychologist standpoint, assuming that mysticism is subject to the same type of forces and factors as any other human behavior. (For the purposes of the dissertation, a mystic is defined as one who centers his life on God and strives for "union" with him.) Questions of theology and philosophy were excluded from the study, and focus was made on the experience of the mystics. Biographies and, where available, autobiographies of the mystics were analyzed and rated using the categories developed by Henry A. Murray et al., known as the "need-press" theory. Only those elements susceptible to analysis using extant psychological methods and techniques were considered. The mystics were limited to those from Western Christendom. Because of the subjectivity involved in the classification of the biographical material, a second rater independently rated the same material. The two raters agreed on more than three-fourths of the classifications; Pearson correlations ranged from .86 to .97 [TRUNCATED

Solid Modeling Aerospace Research Tool (SMART) user's guide, version 2.0

The Solid Modeling Aerospace Research Tool (SMART) software package is used in the conceptual design of aerospace vehicles. It provides a highly interactive and dynamic capability for generating geometries with Bezier cubic patches. Features include automatic generation of commonly used aerospace constructs (e.g., wings and multilobed tanks); cross-section skinning; wireframe and shaded presentation; area, volume, inertia, and center-of-gravity calculations; and interfaces to various aerodynamic and structural analysis programs. A comprehensive description of SMART and how to use it is provided

Models of OH Maser Variations in U Her

Arecibo spectra of the mainline OH maser emission from U Her over more than a decade show variations of the OH emission over these time scales. These observations are combined with high spatial resolution VLBA maps to investigate the causes of the variations in the velocities of the maser components. Global properties of the dust shell, such as accelerations, variations in the pump and shell-wide magnetic field changes are examined as possibilities, and eliminated. A possible solution to the problem involving plasma turbulence and the local magnetic field is introduced, and the relevant time scales of the turbulence are calculated. The turbulent velocity field yields time scales of the turbulence are calculated. The turbulent velocity field yields time scales that are too long (of order centuries), while the turbulent magnetic field produces variations on appropriate time scales of a few years. A line-of-sight model of the turbulence is developed and investigated. The complete exploration of this solution requires extensive theoretical and observational work. Possible avenues of investigation of the plasma turbulence model are presented.Comment: 23 pages, 17 figures, ApJ: accepted Sept, 199

Genome-wide association study for feed efficiency traits using SNP and haplotype models

Feed costs comprise the majority of variable expenses in beef cattle systems making feed efficiency an important economic consideration within the beef industry. Due to the expense of recording individual feed-intake phenotypes, a genomic-enabled approach could be advantageous toward improving this economically relevant trait complex. A genome-wide association study (GWAS) was performed using 748 crossbred steers and heifers representing seven sire breeds with phenotypes for ADG and ADFI. Animals were genotyped with the BovineSNP50v2 BeadChip containing approximately 54,000 SNP. Both traits were analyzed using univariate SNPbased (BayesC) and haplotype-based (BayesIM) models and jointly using BayesIM to perform a bivariate GWAS. For BayesIM, a hidden Markov model (HMM) of haplotype segments of variable length was built where haplotypes were mapped to clusters based on local similarity. The estimated HMM was then used to assign haplotype cluster genotypes, instead of SNP genotypes, as latent covariates in a Bayesian mixture model. The number of haplotype clusters at each location was assumed to be either 8 (BayesIM8) or 16 (BayesIM16). A total of three univariate analyses for each trait and two bivariate analyses were performed. Posterior SD (PSD) for ADG were 0.28 (0.08), 0.37 (0.11), 0.37 (0.11), 0.35 (0.11), and 0.35 (0.12) for BayesC, BayesIM8, BayesIM16, BayesIM8 bivariate, and BayesIM16 bivariate, respectively. ADFI PSD were 0.30 (0.07), 0.44 (0.13), 0.42 (0.12), 0.38 (0.10), and 0.38 (0.10) for the same models. The top 1% of 1-Mb windows that explained the largest fraction of genetic variation in common between univariate SNP and haplotype models ranged from 24% to 40% and from 20% to 32% for ADG and ADFI, respectively. Spearmen rank correlations between molecular breeding values from SNP and haplotype-based models in the training data were similar for both traits (\u3e0.96) suggesting that either model would lead to similar rankings of animals, although resolution of potential QTL appeared to be greater for BayesIM
