The major advantages of nuclear emulsion for detecting charged particles are its submicron position resolution and sensitivity to minimum ionizing particles. These must be balanced, however, against the difficult manual microscope measurement by skilled observers required for the analysis. We have developed an automated system to acquire and analyze the microscope images from emulsion chambers. Each emulsion plate is analyzed independently, allowing coincidence techniques to be used in order to reject background and estimate error rates. The system has been used to analyze a sample of high-multiplicity Pb-Pb interactions (charged particle multiplicities ∼1100) produced by the 158 GeV/c per nucleon …

Establishment Of Tall Fescue On West Louisiana Coastal Plain Soils (Bulletin #859), W. D. Pitman May 1997

Establishment Of Tall Fescue On West Louisiana Coastal Plain Soils (Bulletin #859), W. D. Pitman

LSU AgCenter Bulletins

Georgia-5 tall fescue was developed for use as a permanent, cool-season pasture grass on the Coastal Plain. The results of two field plot experiments and observations from additional small-plot plantings and 40 acres of pasture for grazing experiments at the Rosepine Research Station provide the basis for this discussion of Georgia-5 tall fescue establishment.

The Angiotensin Converting Enzyme And Blood Pressure In Jamaicans, Terrence Forrester, Norma Mcfarlane-Anderson, Franklyn I. Bennett, Rainford Wilks, Richard Cooper, Charles Rotimi, Linda Morrison, Ryk Ward May 1997

The Angiotensin Converting Enzyme And Blood Pressure In Jamaicans, Terrence Forrester, Norma Mcfarlane-Anderson, Franklyn I. Bennett, Rainford Wilks, Richard Cooper, Charles Rotimi, Linda Morrison, Ryk Ward

Faculty Publications

An insertion/deletion (I/D) polymorphism of the angiotensin I converting enzyme gene influences the level of serum angiotensin converting enzyme activity and has been associated with risk of several cardiovascular conditions. The relationship to blood pressure remains uncertain, however. We conducted a population-based survey in Kingston, Jamaica, to examine the association between angiotensin converting enzyme genotype, angiotensin converting enzyme serum activity and blood pressure. Serum angiotensin converting enzyme activity was measured and genotyping performed for the I/D polymorphism in 500 community residents. The overall prevalence of the D allele was 59.3%. Angiotensin converting enzyme genotype was not significantly related to blood …

Ill-Posedness Of A Double-Null Free-Evolution Scheme For Black Hole Spacetimes, Carsten Gundlach, Jorge Pullin Apr 1997

Ill-Posedness Of A Double-Null Free-Evolution Scheme For Black Hole Spacetimes, Carsten Gundlach, Jorge Pullin

Faculty Publications

We suggest that 'free-evolution' integration schemes for the Einstein equations (that do not enforce constraints) may contain exponentially growing modes that render them useless in numerical integrations of black hole spacetimes, independently of how the equations are differenced. As an example we consider the evolution of Schwarzschild and Reissner-Nordström spacetimes in double-null coordinates.

Substitutions At Position 146 Of Cytochrome B Affect Drastically The Properties Of Heme B(L) And The Q(O) Site Of Rhodobacter Capsulatus Cytochrome Bc1 Complex, A. Sami Saribaş, Huangen Ding, P. Leslie Dutton, Fevzi Daldal Mar 1997

Substitutions At Position 146 Of Cytochrome B Affect Drastically The Properties Of Heme B(L) And The Q(O) Site Of Rhodobacter Capsulatus Cytochrome Bc1 Complex, A. Sami Saribaş, Huangen Ding, P. Leslie Dutton, Fevzi Daldal

Faculty Publications

The cytochrome (cyt) b subunit of ubihydroquinone: cytochrome c oxidoreductase(bc1 complex) contains four invariant glycine (G) residues proposed to be essential for proper packing of the high and low potential (b(H) and b(L)) hemes of the bc1 complex. One of these residues, G146 located in the transmembrane helix C of cyt b of Rhodobacter capsulatus, was substituted with A and V using site-directed mutagenesis, and the effects of these substitutions on the properties of the ubiquinone oxidation (Q(o)) site and heme b(L) of the bc1 complex were analyzed. The mutants G146A and V produced properly assembled but catalytically defective bc1 …

A search for neutrino oscillations of the type ν̄μ → ν̄c has been conducted at the Los Alamos Meson Physics Facility using ν̄μ from muon decay at rest. Evidence for this transition has been reported previously. This paper discusses in detail the experimental setup, detector operation and neutrino source, including aspects relevant to oscillation searches in the muon decay-at-rest and pion decay in flight channels.

Matroids Arisen From Matrogenic Graphs, Guoli Ding, Peter L. Hammer Mar 1997

Matroids Arisen From Matrogenic Graphs, Guoli Ding, Peter L. Hammer

Faculty Publications

Let G be a finite simple graph and let ℐ(G) be the set of subsets X of V(G) such that the subgraph of G induced by X is threshold. If ℐ(G) is the independence system of a matroid, then G is called matrogenic [3]. In this paper, we characterize matroids arising from matrogenic graphs.

Native And Multimeric Vitronectin Exhibit Similar Affinity For Heparin: Differences In Heparin Binding Properties Induced Upon Denaturation Are Due To Self-Association Into A Multivalent Form, Ping Zhuang, Anthony I. Chen, Cynthia B. Peterson Mar 1997

Native And Multimeric Vitronectin Exhibit Similar Affinity For Heparin: Differences In Heparin Binding Properties Induced Upon Denaturation Are Due To Self-Association Into A Multivalent Form, Ping Zhuang, Anthony I. Chen, Cynthia B. Peterson

Faculty Publications

For many years, the concept that the heparin-binding sequence is sequestered within vitronectin and exposed upon denaturation of the protein has guided experimental design and interpretation of related structure- function studies on the protein. To evaluate binding of heparin to both native and denatured/renatured vitronectin, methods for monitoring binding in solution have been developed. A fluorescence method based on changes in an extrinsic probe attached to heparin has been used to evaluate heparin binding to native and denatured/renatured vitronectin. This approach indicates that there are not major differences in intrinsic heparin-binding affinities between native and renatured protein and invalidate the …

Wetland Loss In The Northern Gulf Of Mexico: Multiple Working Hypotheses, R. Eugene Turner Mar 1997

Wetland Loss In The Northern Gulf Of Mexico: Multiple Working Hypotheses, R. Eugene Turner

Faculty Publications

I examined four hypotheses about causes for the dramatically high coastal wetland losses (0.86% yr−1) in the northern Gulf of Mexico: an extensive dredged canal and spoil bank network, a decline in sediments in the Mississippi River during the 1950s, Mississippi River navigation and flood protection levees, and salinity changes. Natural factors contributing to these habitat changes include eustatic sea-level rise and geological compaction, which appear to have remained relatively constant this century, although variation does occur. These four hypotheses were tested using data on land-to-water changes in 15-min quadrangle maps inventoried for four intervals between the 1930s and 1990. …

The Use Of Fluorescent Probes To Characterize Conformational Changes In The Interaction Between Vitronectin And Plasminogen Activator Inhibitor-1, Angelia Gibson, Kunnumal Baburaj, Duane E. Day, Ingrid Verhamme, Joseph D. Shore, Cynthia B. Peterson Feb 1997

The Use Of Fluorescent Probes To Characterize Conformational Changes In The Interaction Between Vitronectin And Plasminogen Activator Inhibitor-1, Angelia Gibson, Kunnumal Baburaj, Duane E. Day, Ingrid Verhamme, Joseph D. Shore, Cynthia B. Peterson

Faculty Publications

Plasminogen activator inhibitor-1 (PAI-1), the primary inhibitor of tissue-type plasminogen activator and urokinase, is known to convert readily to a latent form by insertion of the reactive center loop into a central β- sheet. Interaction with vitronectin stabilizes PAI-1 and decreases the rate of conversion to the latent form, but conformational effects of vitronectin on the reactive center loop of PAI-1 have not been documented. Mutant forms of PAI-1 were designed with a cysteine substitution at either position P1' or P9 of the reactive center loop. Labeling of the unique cysteine with a sulfhydryl-reactive fluorophore provides a probe that is …
