Comparison Of Viscous Damping In Unsaturated Soils, Compression And Shear, Paul Michaels

Paul Michaels

Geophysical down-hole surveys can be used to measure the small strain dynamic properties of soils by the effects these properties have on wave propagation. The relevant effects include amplitude decay (corrected for beam divergence) and velocity dispersion. In this paper, down-hole data collected during the GeoInstitute's Denver 2000 field day are presented and analyzed as a Kelvin-Voigt solid. Findings for these unsaturated soils include viscous damping and stiffness which differ significantly for shear and compressional waves. A strong viscous damping is observed in compression, but weak damping is presented in shear. Lumped parameter constitutive models are discussed which mathematically represent …

Comparative Studies On Oxygen Mass Transfer For The Design And Development Of A Single-Use Fermentor, Kristan L. Sorenson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Accurate experimental oxygen mass transfer coefficient, a measure of how quickly oxygen travels from a gas bubble to the bulk liquid, is important for comparing performance and for evaluating the oxygen transfer capability of a fermentor. Delays in probe response and changing gas volumes upon start-up of gassing affect the accuracy of oxygen transfer measurements. To mitigate these inaccuracies, a standard correction procedure for oxygen mass transfer data was established for highly oxygenated, well-mixed fermentation systems. Probe response time correction was generated by applying a second-order response model to dissolved oxygen probes and shown to be effective within 4%. By …

God Among The Gods: An Analysis Of The Function Of Yahweh In The Divine Council Of Deuteronomy 32 And Psalm 82, Daniel F. Porter

Masters Theses

The importance of the Ugaritic texts discovered in 1929 to ancient Near Eastern and Biblical Studies is one of constant debate. The Ugaritic texts offer a window into the cosmology that shaped the ancient Near East and Semitic religions. One of the profound concepts is the idea of a divine council and its function in maintaining order in the cosmos. Over this council sits a high god identified as El in the Ugaritic texts whose divine function is to maintain order in the divine realm as well on earth. Due to Ugarit's involvement in the ancient world and the text's …

Who Maketh The Clouds His Chariot: The Comparative Method And The Mythopoetical Motif Of Cloud-Riding In Psalm 104 And The Epic Of Baal, Jordan Wesley Jones

Masters Theses

Alleging parallels between Scripture and other ancient Near Eastern texts has always been a matter of controversy. The controversy has resulted from criticism of the comparative method by those who accuse its users of being overly simplistic or reckless when applying their particular approaches to the texts. This recklessness has resulted in alleged connections that are now considered very loose, unjustified, and harmful to the context of Scripture. In order to avoid the dreaded "parallelomania" that has resulted from hasty conclusions in comparative studies, it is necessary to approach alleged comparative units in a more concrete fashion, synthesizing the best …
