Land And Resource Management On Typic Quartzipsamments, David Kulhavy, W. D. Tracey, W. G. Ross Jan 1991

Land And Resource Management On Typic Quartzipsamments, David Kulhavy, W. D. Tracey, W. G. Ross

Faculty Publications

Survival and growth of seven species/treatment combinations were tested on Tonkawa fine sand (thermic, coated Typic Quartzipsamment) in Nacogdoches County, Texas. In January 1983, seedlings were hand-planted on an intensively prepared clearcut site on the Tonkawa soil series in northern Nacogdoches County. Tonkawa sands serve as recharge zones for the Carrizo aquifer, a major source of clean groundwater for much of East Texas. Intensive management practices on this sensitive site created severe site conditions, providing incentive for the study. Species/ treatment combinations were: untreated loblolly (Pinus taeda L.) pine (LOB/CON); Terra-SorbTM -treated loblolly (LOB/Tm);olin clay slurry-treated loblolly (LOB/CLA); untreated slash …

Physiology Of Red-Cockaded Woodpecker Cavity Trees: Implications For Management, William G. Ross, David Kulhavy, Richard N. Conner, Jianghua Sun Jan 1991

Physiology Of Red-Cockaded Woodpecker Cavity Trees: Implications For Management, William G. Ross, David Kulhavy, Richard N. Conner, Jianghua Sun

Faculty Publications

Resin flow and tree moisture stress, frequently used as indicators of pine susceptibility to pine bark beetle (Dendroctonus frontalis Zimm.) attack, were measured in loblolly (Pinus taeda L.) and shortleaf (P. echinata Mill.) pines red-cockaded woodpecker [Picoides boreal& (Vieillot)] cavity trees in the Angelina and Davy Crockett National Forests in eastern Texas. No differences in moisture stress were found, whereas resin flow between different types of cavity trees and control or potential trees varied by site and species. It was concluded that effects of red-cockaded woodpecker activity on host tree susceptibility to southern pine beetle will vary by site, tree …

Causes Of Mortality Of Red-Cockaded Woodpecker Cavity Trees, Richard N. Conner, D. Craig Rudolph, David Kulhavy, Ann Snow Jan 1991

Causes Of Mortality Of Red-Cockaded Woodpecker Cavity Trees, Richard N. Conner, D. Craig Rudolph, David Kulhavy, Ann Snow

Faculty Publications

Over a 13-year period we examined the mortality of cavity trees (n = 453) used by red-cockaded woodpeckers (Picoides borealis) on national forests in eastern Texas. Bark beetles (53%), wind snap (30%), and fire (7%) were the major causes of cavity tree mortality. Bark beetles were the major cause of mortality in loblolly (Pinus taeda) and shortleaf (P. echinata) pines, whereas fire was the major cause in longleaf pines (P. palustris). Cavity trees on the Angelina National Forest (NF) were dying at a higher rate than new, complete cavities were being excavated. Cavity enlargement by pileated woodpeckers (Dryocopus pileatus) on …

The Oregon Medicaid Program: Is It Just?, Maxwell J. Mehlman Jan 1991

The Oregon Medicaid Program: Is It Just?, Maxwell J. Mehlman

Faculty Publications

While the objective of expanding the Oregon Medicaid program is commendable, the means adopted by the Oregon legislature to control the costs of the expansion are problematic. This paper examines the legislature's approach from a legal perspective. The first part of the paper determines whether it is consistent with federal and state law governing the Medicaid program. Oregon is seeking waivers from any conflicting federal requirements, and since there do not appear to be any constitutional impediments, the key question is whether the waivers should be granted as a matter of sound public policy. The second and third parts of …

Identification Of The Intermediate Allosteric Species In Human Hemoglobin Reveals A Molecular Code For Cooperative Switching, Margaret A. Daugherty, Madeline A. Shea, Jeremy A. Johnson, Vince J. Licata, George J. Turner, Gary K. Ackers Jan 1991

Identification Of The Intermediate Allosteric Species In Human Hemoglobin Reveals A Molecular Code For Cooperative Switching, Margaret A. Daugherty, Madeline A. Shea, Jeremy A. Johnson, Vince J. Licata, George J. Turner, Gary K. Ackers

Faculty Publications

The 10 ligation species of human cyanomethemoglobin were previously found to distribute into three discrete cooperative free energy levels according to a combinatorial code (i.e., dependent on both the number and configuration of ligated subunits). Analysis of this distribution showed that the hemoglobin tetramer occupies a third allosteric state in addition to those of the unligated (T) and fully ligated (R) species. To determine the nature of the intermediate allosteric state, we have studied the effects of pH, temperature, and single-site mutations on its free energy of quaternary assembly, in parallel with corresponding data on the deoxy (T) and fully …

Simplified Procedure For The Isolation Of Intact Chloroplasts From Chlamydomonas Reinhardtii, Catherine B. Mason, Sharon Matthews, Terry M. Bricker, James V. Moroney Jan 1991

Simplified Procedure For The Isolation Of Intact Chloroplasts From Chlamydomonas Reinhardtii, Catherine B. Mason, Sharon Matthews, Terry M. Bricker, James V. Moroney

Faculty Publications

A simple procedure that yields highly purified intact chloroplasts from Chlamydomonas reinhardtii is described. This procedure involves breakage of cell wall-deficient cells by passing them through a narrow bore syringe needle. The intact chloroplasts are then purified from the crude homogenate by differential centrifugation and Percoll gradient centrifugation. This procedure generates relatively high yields of chloroplasts capable of CO2 fixation. These chloroplasts were characterized by electron microscopy, marker enzyme analysis, and ferricyanide exclusion. Transmission electron microscopy indicates that these chloroplasts retain their pyrenoids and eyespots. Scanning electron microscopy confirms that the characteristic cup shape of C. reinhardtii chloroplasts persists in …

Role Of A Carboxyl-Terminal Helix In The Assembly, Interchain Interactions, And Stability Of Aspartate Transcarbamoylase, Cynthia B. Peterson, H. K. Schachman Jan 1991

Role Of A Carboxyl-Terminal Helix In The Assembly, Interchain Interactions, And Stability Of Aspartate Transcarbamoylase, Cynthia B. Peterson, H. K. Schachman

Faculty Publications

The six individual catalytic polypeptide chains within the two catalytic trimers of Escherichia coli aspartate transcarbamoylase (ATCase; EC 2.1.3.2) are folded into two discrete structural domains interconnected in part by helix 12, which comprises residues 285-305 and is located near the carboxyl terminus of the chain. The essential role of this helix in folding of the chains and their assembly into ATCase was demonstrated by introducing a stop codon at the position corresponding to amino acid 284, 291, or 299. Cells containing these mutations are pyrimidine auxotrophs lacking ATCase-like protein in cell extracts. In contrast, stable active enzyme is formed …

Computer-Simulated Evaluation Of Possible Mechanisms For Quenching Heavy Metal Ion Activity In Plant Vacuoles: I. Cadmium, Jian Wang, Bill P. Evangelou, Mark T. Nielsen, George J. Wagner Jan 1991

Computer-Simulated Evaluation Of Possible Mechanisms For Quenching Heavy Metal Ion Activity In Plant Vacuoles: I. Cadmium, Jian Wang, Bill P. Evangelou, Mark T. Nielsen, George J. Wagner

Faculty Publications

Various mechanisms have been suggested for the quenching of Cd ion activity in plant vacuoles. These include solution complexation with organic acids and sulfhydryl-containing peptides and precipitation as sulfides. Because direct experimental support for these mechanisms is lacking and difficult to obtain, we have used a computer model to evaluate the quenching role of possible organic and inorganic ligands of tobacco cultured cells exposed to Cd. Results of this thermodynamic evaluation, which assumes that a chemical equilibrium state is met in the vacuole, support the conclusion that sulfhydryl-containing peptides and certain organic acids may form soluble Cd complexes. Although complexation …

Evaluating Acrosome Interference Contrast Reaction Steps With Brightfield And Differential Microscopy Techniques, H. C. Steinholt, J. E. Chandler, V. Tirado

Faculty Publications

Acrosomal integrity of bovine spermatozoa was evaluated using naphthol yellow S-erythrosine B stain with bright field microscopy, .2% glutaraldehyde fixation with Nomarski optics, and live wet smears with Nomarski optics to compare the evaluation techniques. Four ejaculates per two Holstein bulls were enriched through a Percoll gradient, capacitated with heparin, and acrosome-reacted with lysophosphatidylcholine to prepare spermatozoa for in vitro fertilization. Spermatozoa samples were taken after each preparatory step, and percentage of intact acrosomes was evaluated with the stain, .2% glutaraldehyde, and live wet smear. Acrosomal integrity decreased with each preparatory step across all techniques. The decrease in integrity from …

Missing Evidence, Dale A. Nance Jan 1991

Missing Evidence, Dale A. Nance

Faculty Publications

Given the nature of my enterprise, I resist stating a specific thesis. Nevertheless, for the reader who wants an organizing or motivating principle, I offer the following two recurrent themes. First, I want to examine the relationship of traditional admissibility rules to the problem of missing evidence and to other forms of juridical response to that problem. The reason for this interest will be explained in the next section. Second, I want to investigate, as we proceed, the extent to which the regulation of proof, evidence law broadly conceived, is instrumentally related to accuracy or truth seeking, and the extent …
