Locally Optimally Emitting Clouds And The Origin Of Quasar Emission Lines, Jack Baldwin, Gary J. Ferland, Kirk Korista, Dima Verner

Physics and Astronomy Faculty Publications

The similarity of quasar line spectra has been taken as an indication that the emission line clouds have preferred parameters, suggesting that the environment is subject to a fine-tuning process. We show here that the observed spectrum is a natural consequence of powerful selection effects. We computed a large grid of photoionization models covering the widest possible range of cloud gas density and distance from the central continuum source. For each line only a narrow range of density and distance from the continuum source results in maximum reprocessing efficiency, corresponding to "locally optimally emitting clouds" (LOCs). These parameters depend on …

These materials are useful as pharmaceutical agents for oral or parenteral, e.g. intravenous administration to patients suffering from acute central nervous system oxidation as occurs in a stroke or from gradual central nervous system oxidation which can exhibit itself as progressive central nervous system function loss. The materials are also used to ameliorate the side effects of oxidative-damage causing antineoplastic disease treatments.

Phenyl Butyl Nitrone Compositions And Methods For Treatment Of Oxidative Tissue Damage, John M. Carney, Robert A. Floyd

Pharmacology and Nutritional Sciences Faculty Patents

Compositions for treating tissue damage from ischemia contain PBN, or active derivatives thereof, which are active during ischemia in preventing ATP depletion of the cells which predisposes them to subsequent injury during reperfusion, and which are active during reperfusion as oxygen radical scavengers, in a suitable pharmaceutical carrier for systemic or local administration, especially to the CNS, spinal column and eyes. Based on animal studies, the dosage for treating damage due to stroke is in the range of 10 to 300 mg/kg. Similar dosages are useful in treating damage resulting from free radical generation during inflammation, either as a product …

Broad Ne Viii Λ744 Emission From The Quasar Pg 1148+549, Fred Hamann, Joseph C. Shields, Gary J. Ferland, Kirk T. Korista

Physics and Astronomy Faculty Publications

We discuss the probable detection of broad Ne VIII λ774 emission from the z_ɛ = 0.978 quasar PG 1148+549, and we use spectral synthesis calculations to study the physical conditions in the line-forming gas. The theoretical predictions and the measured line wavelength both support Ne VIII λ774 as the most likely identification.

Our calculations show that Ne VIII λ774 forms in hotter and more highly ionized gas than previously recognized in the broad emission line region. If the gas is photoionized by a standard active galactic nucleus continuum, the observed Ne VIII equivalent width, the Ne VIII/O VI flux …

Logger Killed When Log Rolls Off Truck At Sawmill, Kentucky Injury Prevention And Research Center

Fatality Case Reports--Tractors/Logging

A 63-year-old male logger was struck by a log that rolled off a loaded truck at a sawmill. The victim was working with his two nephews that day and they were preparing to unload the logs from their two trucks. The logs were stacked at least twice as high as the standards on the sides of the flatbed trailers. As one nephew began to unchain the logs from his truck, the victim walked up to the truck, out of view of his nephew. When the chains were released, a log at the top of the load rolled off and struck …

The Geometry And Kinematics Of The Broad-Line Region In Ngc 5548 From Hst And Iue Observations, Ignaz Wanders, Mike R. Goad, Kirk T. Korista, Bradley M. Peterson, Keith Horne, Gary J. Ferland, Anuradha P. Koratkar, Richard W. Pogge, Joseph C. Sheilds

Physics and Astronomy Faculty Publications

The spatial and radial velocity distribution of broad-line-emitting gas in the Seyfert 1 galaxy NGC 5548 is examined through the process of reverberation mapping, which is done by detailed comparison of continuum and emission-line variations. Recent spectroscopic monitoring of NGC 5548 with HST and IUE allows us to resolve the "transfer function" (TF) that relates the continuum and emission-line variability. We also examine the radial velocity-resolved TFs, and confirm that predominantly radial motions of the line-emitting clouds can be excluded. We find that a broad-line region comprised of clouds that are orbiting a central source of mass ~10⁸ M …

Nitrous Oxide Loss From Poultry Manure-Amended Soil After Rain, Mark S. Coyne, A. Villalba, Robert L. Blevins

Plant and Soil Sciences Faculty Publications

Land application of poultry wastes in Kentucky will increase as the broiler industry grows. If poultry manure stimulates N₂O loss from soil it will reduce the fertilizer N value of this waste. In contrast, stimulated N₂O loss in grass filter strips receiving the runoff from manured fields could help reduce contamination of surface water by NO⁻₃. Our objectives were to determine (i) if poultry manure stimulated N₂O loss in soil after rainfall and (ii) if there was an edge-of-field effect on N₂O loss in grass filters intercepting runoff from …

Bankruptcy Redistributive Policies And The Limits Of The Judicial Process, Christopher W. Frost

Law Faculty Scholarly Articles

Business failure negatively affects a broad range of interests, yet the bankruptcy process directly protects only a small segment of interest-holders: the creditors. Some commentators argue for expansion of that protection to encompass redistributive norms and provide for the interests of non-investors in the failed business. The Bankruptcy Reform Act of 1994’s establishment of a national commission to study the bankruptcy process and its broader policy implications brings with it the opportunity to consider that redistributive argument and perhaps change the process to include the interests of non-investors under the reorganization umbrella. This Article responds to those who would have …

Groundwater Study: Toyota Motor Manufacturing, Usa Georgetown, Kentucky, Gary Felton, Lyle V. A. Sendlein, Teri Dowdy, Daryl Hines

KWRRI Research Reports

An eighteen month study of the Toyota Motor Manufacturing (TMM) plant site and the surrounding area was undertaken. The basic charge for this project was to characterize the groundwater that is potentially impacted by the TMM plant site. This included occurrence, flow direction, and, if possible, velocity. Because the area is karstified (has sinkholes, springs, caves, etc.) surface water and groundwater are intimately connected and, hence, surface water was frequently an important component of this work.

Data from TMM construction plans and monitoring work done subsequent to construction were elicited from the various repositories within the TMM infrastructure. Aerial color …

Farm Worker Killed In Tractor Rollover On Public Roadway, Kentucky Injury Prevention And Research Center

Fatality Case Reports--Tractors/Logging

A 21-year-old farm worker was killed in a tractor rollover incident. The victim was driving a tractor on a secondary public road, pulling an unloaded 18-foot flatbed trailer, when he lost control. After the tractor wheels went off the right side of the road, the victim overcorrected, which caused the vehicle to become unbalanced; he was thrown from the tractor as it overturned into a ditch. It was not equipped with an appropriate rollover protective structure (ROPS) or a seatbelt. The unit, which included a canopy, had been installed to provide shade on summer days and cover in occasional downpours, …

A 22-year-old logger was killed after being struck on the head by a falling snag (dead standing tree). The victim was working with one co-worker, who was selectively cutting trees which were approximately 22 inches in diameter. Standing approximately three feet from the tree being cut, the victim was not wearing a hard hat. The cut tree broke a snag about 35 feet up, causing the snag to fall and strike the victim on the head. The co-worker (tree feller) shouted to the victim, but he was unable to move away in time to avoid being hit. FACE investigators concluded …

Logger Killed In Endloader Rollover, Kentucky Injury Prevention And Research Center

Fatality Case Reports--Tractors/Logging

A 41-year-old self-employed logger was killed when the endloader he was driving down a steep mountain road rolled over. Recent rainfall had made the dirt road wet and muddy. Tire marks left in the mud indicated that as the vehicle began to slide downhill, it hit the right embankment, causing it to veer to the left side of the road and roll over several times before coming to rest at the bottom of the dropoff on its left side. The victim was ejected from the vehicle and was found lying facedown about halfway between the edge of the roadway and …

Temperature Fluctuations In Photoionized Nebulae, J. B. Kingdon, Gary J. Ferland

Physics and Astronomy Faculty Publications

Recombination lines in gaseous nebulae frequently yield parent-ion abundances that are several times larger than abundances derived from forbidden lines. One possible explanation for this discrepancy is the presence of temperature fluctuations. We examine temperature fluctuations in model nebulae by utilizing Peimbert's t² parameter. We have run large grids of models, varying the stellar temperature and the total hydrogen density. We consider two abundance sets: The first uses "typical" planetary nebulae abundances, while the second examines the effect of increasing the metals and grains by a factor of 3. We also consider both a constant density distribution and one …

Involvement Of P59FynT In Interleukin-5 Receptor Signaling, Mark W. Appleby, James D. Kerner, Sylvia Chien, Charles R. Maliszewski, Subbarao Bondada, Roger M. Perlmutter

Microbiology, Immunology, and Molecular Genetics Faculty Publications

Previous studies implicate the nonreceptor protein tyrosine kinase (PTK) p59fyn in the propagation of signals from the B cell antigen receptor. To elucidate the functions of this kinase, we examined B cell responsiveness in mice engineered to lack the hematopoietic isoform of p59fyn. Remarkably, antigen receptor signaling was only modestly defective in fyn^Tnull B cells. In contrast, signaling from the interleukin (IL)-5 receptor which ordinarily provides a comitogenic stimulus with antiimmunoglobulin, was completely blocked. Our results document the importance of p59fyn^T in IL-5 responses in B cells, and they support a general model …

God Is As God Does: Law, Anthropology, And The Definition Of "Religion", James M. Donovan

Law Faculty Scholarly Articles

This Article first discusses the judicial deliberations upon the definition of religion. That discussion adopts a chronological sequence because, in legal matters, that is the one that counts.

It can be a tedious, but not particularly difficult task to summarize the legal struggle to define religion. The strategy applied to evaluate the product of that struggle is intellectual triangulation, whereby bearings from two fixed positions are used to specify that of that third. By analogy, the correct definition of "religion" can be identified by finding where the legal efforts intersect with an independent sighting of the same target. Where this …
