MARGIE will be a large-area, wide field-of-view, hard x- ray/gamma-ray imaging telescope capable of providing accurate positions for faint gamma-ray bursts in near-real- time and of performing a sensitive survey of both steady and transient cosmic sources. The instrument is designed to image faint bursts at the low-intensity end of the log N - log S distribution. MARGIE was recently selected by NASA for a mission-concept study for an Ultra Long Duration Balloon flight. We describe a program to develop an instrument based on the new detector technology of either cadmium zinc telluride room-temperature semiconductors or pixelated cesium iodide scintillators …


Depositional And Diagenetic Relationships Of The Honaker-Nolichucky Formational Boundary (Middle Cambrian, Conasauga Group), Southern Appalachians, Gary Alan Ottinger Aug 1999

Depositional And Diagenetic Relationships Of The Honaker-Nolichucky Formational Boundary (Middle Cambrian, Conasauga Group), Southern Appalachians, Gary Alan Ottinger

Masters Theses

The upper Honaker and lower Nolichucky Formations (Middle Cambrian, Conasauga Group) in northeastern Tennessee comprise part of a thick pericratonic Cambro-Ordovician passive margin sequence along the eastern edge of North America. Throughout the Cambrian, the interplay of autocyclic controls, including sediment supply, tectonism and accompanying subsidence, and eustasy, resulted in various sedimentary architectures, including the Conasauga platform and intrashelf basin adjacent to the craton. To date, the Middle Cambrian westerly carbonate sections adjacent to and within the intrashelf basin (near Knoxville) have been studied in considerable detail. Particularly, these studies have proposed a third-order sequence boundary near Knoxville as well …

Biogeography Of The Short-Tailed Shrews (Blarina Brevicauda And B. Carolinensis) In The Tennessee River Valley And Adjacent Areas Of The Midsouth, Michael Jeffries Apr 1999

Biogeography Of The Short-Tailed Shrews (Blarina Brevicauda And B. Carolinensis) In The Tennessee River Valley And Adjacent Areas Of The Midsouth, Michael Jeffries

Honors Theses

In response to conflicting reports of the distribution of the two species of Blarina (B. brevicauda and B. carolinensis) in the Tennessee Valley area, specimens from The Natural History Museum of The University of Tennessee at Chattanooga and The University of Georgia were analyzed. Cranial measurements were used in both a discriminant function analysis and a principle components analysis to determine species assignments. Blarina brevicauda was found in central Tennessee, the highlands of the Cumberland Plateau, and the mountains of far east Tennessee, whereas B. carolinensis was found in the Ridge and Valley of southeast Tennessee, separated from B. brevicauda …


State To State Ne-Co Rotationally Inelastic Scattering, Stiliana Antonova, Ao Lin, Antonis P. Tsakotellis, George C. Mcbane Mar 1999

State To State Ne-Co Rotationally Inelastic Scattering, Stiliana Antonova, Ao Lin, Antonis P. Tsakotellis, George C. Mcbane

Peer Reviewed Articles

Measurements of state-to-state integral cross sections for rotational excitation of CO by collisions with Ne are reported. The measurements were performed in crossed molecular beams with resonance enhanced multiphoton detection at collision energies of 711 and 797 cm-1. The cross sections display strong interference structure, with a propensity for odd Δj below Δj=10. Predictions of the ab initio potential surface of Moszynski et al. [J. Phys. Chem. A 101, 4690 (1997)] and the new ab initio surface of McBane and Cybulski [J. Chem. Phys. 110, 11734 (1999), preceding paper] are compared to the …


A Bramatherium Skull (Giraffidae, Mammalia) From The Late Miocene Of Kavakdere (Central Turkey). Biogeographic And Phylogenetic Implications, Deniş Geraads, Erksin Güleç Feb 1999

A Bramatherium Skull (Giraffidae, Mammalia) From The Late Miocene Of Kavakdere (Central Turkey). Biogeographic And Phylogenetic Implications, Deniş Geraads, Erksin Güleç

Bulletin of the Mineral Research and Exploration

A sub-adult skull from the Late Miocene of Kavakdere, desciribed and referred to the Indian genus Bramatherium. increases the similarity between the Indian sub-continent and the Greco-Iranian province. The contents and subdivisions of the subfamily Sivatheriinae are reviewed, with 2 main groups being recognized, based upon the homologies and position of horns. They are perhaps both of western European origin.


Exposure To Atmospheric Radon, Daniel J. Steck, R. William Field, Charles F. Lynch Feb 1999

Exposure To Atmospheric Radon, Daniel J. Steck, R. William Field, Charles F. Lynch

Physics Faculty Publications

We measured radon (222Rn) concentrations in Iowa and Minnesota and found that unusually high annual average radon concentrations occur outdoors in portions of central North America. In some areas, outdoor concentrations exceed the national average indoor radon concentration. The general spatial patterns of outdoor radon and indoor radon are similar to the spatial distribution of radon progeny in the soil. Outdoor radon exposure in this region can be a substantial fraction of an individual's total radon exposure and is highly variable across the population. Estimated lifetime effective dose equivalents for the women participants in a radon-related lung cancer …

A Biogeochemical Comparison Of Fossil (Carboniferous) And Modern Crustose Red Algae, Michael A. Kruge, John E. Utgaard, William Ferry Jan 1999

A Biogeochemical Comparison Of Fossil (Carboniferous) And Modern Crustose Red Algae, Michael A. Kruge, John E. Utgaard, William Ferry

Department of Earth and Environmental Studies Faculty Scholarship and Creative Works

The nature of the contribution of the various types of algae to sedimentary organic matter continues to be a topic of research interest. Crustose red algae have however received less attention than other types. The fossil calcareous red algae (Rhodophyta) analyzed in this study are two relatively unrecrystallized specimens of Parachaetetes (Family Solenoporacea) from the lower part of the Ste. Genevieve Formation (Carboniferous, Visean) in Union County, Illinois, USA. They occurred in the patch reef phase of a small carbonate mudmound-patchreef. The three modern specimens (collected and identified by F. Collier) are the crustose algae Lithothamnion, Clathromorphum and Phymatolithon …
