Excited Bands In Odd-Mass Rare-Earth Nuclei, Carlos E. Vargas, Jorge G. Hirsch, Jerry P. Draayer Jan 2002

Excited Bands In Odd-Mass Rare-Earth Nuclei, Carlos E. Vargas, Jorge G. Hirsch, Jerry P. Draayer

Faculty Publications

Normal parity bands in [Formula Presented] and [Formula Presented] are studied using the pseudo-SU(3) shell model. Energies and [Formula Presented] transition strengths of states belonging to six low-lying, same-parity rotational bands in each nuclei are considered. The pseudo-SU(3) basis includes states with pseudospin 0 and 1, and [Formula Presented] and [Formula Presented] for even and odd nucleon numbers, respectively. States with pseudospin 1 and [Formula Presented] must be included for a proper description of some excited bands. © 2002 The American Physical Society.


Mixed-Mode Shell-Model Theory For Nuclear Structure Studies, V. G. Gueorguiev, W. E. Ormand, C. W. Johnson, J. P. Draayer Jan 2002

Mixed-Mode Shell-Model Theory For Nuclear Structure Studies, V. G. Gueorguiev, W. E. Ormand, C. W. Johnson, J. P. Draayer

Faculty Publications

We introduce a shell-model theory that combines traditional spherical states, which yield a diagonal representation of the usual single-particle interaction, with collective configurations that track deformations, and test the validity of this mixed-mode, oblique-basis shell-model scheme on [Formula Presented] The correct binding energy (within 2% of the full-space result) as well as low-energy configurations that have greater than 90% overlap with full-space results are obtained in a space that spans less than 10% of the full space. The results suggest that a mixed-mode shell-model theory may be useful in situations where competing degrees of freedom dominate the dynamics and full-space …


Numerical Methods For The Simulation Of Dynamical Mass Transfer In Binaries, Patrick M. Motl, Joel E. Tohline, Juhan Frank Jan 2002

Numerical Methods For The Simulation Of Dynamical Mass Transfer In Binaries, Patrick M. Motl, Joel E. Tohline, Juhan Frank

Faculty Publications

We describe computational tools that have been developed to simulate dynamical mass transfer in semidetached, polytropic binaries that are initially executing synchronous rotation upon circular orbits. Initial equilibrium models are generated with a self-consistent field algorithm; models are then evolved in time with a parallel, explicit, Eulerian hydrodynamics code with no assumptions made about the symmetry of the system. Poisson's equation is solved along with the equations of ideal fluid mechanics to allow us to treat the nonlinear tidal distortion of the components in a fully self-consistent manner. We present results from several standard numerical experiments that have been conducted …


Hyperbolicity Of The Baumgarte-Shapiro-Shibata-Nakamura System Of Einstein Evolution Equations, Olivier Sarbach, Gioel Calabrese, Jorge Pullin, Manuel Tiglio Jan 2002

Hyperbolicity Of The Baumgarte-Shapiro-Shibata-Nakamura System Of Einstein Evolution Equations, Olivier Sarbach, Gioel Calabrese, Jorge Pullin, Manuel Tiglio

Faculty Publications

We discuss an equivalence between the Baumgarte-Shapiro-Shibata-Nakamura (BSSN) formulation of the Einstein evolution equations, a subfamily of the Kidder-Scheel-Teukolsky formulation, and other strongly or symmetric hyperbolic first order systems with fixed shift and densitized lapse. This allows us to show under which conditions the BSSN system is, in a sense to be discussed, hyperbolic. This desirable property may account in part for the empirically observed better behavior of the BSSN formulation in numerical evolutions involving black holes. © 2002 The American Physical Society.


Stability Properties Of A Formulation Of Einstein's Equations, Gioel Calabrese, Jorge Pullin, Olivier Sarbach, Manuel Tiglio Jan 2002

Stability Properties Of A Formulation Of Einstein's Equations, Gioel Calabrese, Jorge Pullin, Olivier Sarbach, Manuel Tiglio

Faculty Publications

We study the stability properties of the Kidder-Scheel-Teukolsky (KST) many-parameter formulation of Einstein's equations for weak gravitational waves on flat space-time from a continuum and numerical point of view. At the continuum, performing a linearized analysis of the equations around flat space-time, it turns out that they have, essentially, no non-principal terms. As a consequence, in the weak field limit the stability properties of this formulation depend only on the level of hyperbolicity of the system. At the discrete level we present some simple one-dimensional simulations using the KST family. The goal is to analyze the type of instabilities that …


Convergence And Stability In Numerical Relativity, Gioel Calabrese, Jorge Pullin, Olivier Sarbach, Manuel Tiglio Jan 2002

Convergence And Stability In Numerical Relativity, Gioel Calabrese, Jorge Pullin, Olivier Sarbach, Manuel Tiglio

Faculty Publications

It is often the case in numerical relativity that schemes that are known to be convergent for well posed systems are used in evolutions of weakly hyperbolic formulations of Einstein's equations. Here we explicitly show that with several of the discretizations that have been used throughout the years, this procedure leads to nonconvergent schemes. That is, arbitrarily small initial errors are amplified without bound when resolution is increased, independently of the amount of numerical dissipation introduced. The lack of convergence introduced by this instability can be particularly subtle, in the sense that it can be missed by several convergence tests, …


Perturbative Evolution Of Conformally Flat Initial Data For A Single Boosted Black Hole, Reinaldo J. Gleiser, Gaurav Khanna, Jorge Pullin Jan 2002

Perturbative Evolution Of Conformally Flat Initial Data For A Single Boosted Black Hole, Reinaldo J. Gleiser, Gaurav Khanna, Jorge Pullin

Faculty Publications

The conformally flat families of initial data typically used in numerical relativity to represent boosted black holes are not those of a boosted slice of Schwarzschild spacetime. If such data are used for each black hole in a collision, the emitted radiation will be partially due to the "relaxation" of the individual holes to "boosted Schwarzschild" form. We attempt to compute this radiation by treating the geometry for a single boosted conformally flat hole as a perturbation of a Schwarzschild black hole, which requires the use of second order perturbation theory. In this we attempt to mimic a previous calculation …


Finite Spin-Foam-Based Theory Of Three- And Four-Dimensional Quantum Gravity, Rodolfo Gambini, Jorge Pullin Jan 2002

Finite Spin-Foam-Based Theory Of Three- And Four-Dimensional Quantum Gravity, Rodolfo Gambini, Jorge Pullin

Faculty Publications

Starting from Ooguri's construction for BF theory in three (and four) dimensions, we show how to construct a well defined theory with an infinite number of degrees of freedom. The spin network states that are kept invariant by the evolution operators of the theory are exact solutions of the Hamiltonian constraint of quantum gravity proposed by Thiemann. The resulting theory is the first example of a well defined, finite, consistent, spin-foam-based theory in a situation with an infinite number of degrees of freedom. Since it solves the quantum constraints of general relativity it is also a candidate for a theory …


Close Limit Evolution Of Kerr-Schild Type Initial Data For Binary Black Holes, Olivier Sarbach, Manuel Tiglio, Jorge Pullin Jan 2002

Close Limit Evolution Of Kerr-Schild Type Initial Data For Binary Black Holes, Olivier Sarbach, Manuel Tiglio, Jorge Pullin

Faculty Publications

We eyolve the binary black hole initial data family proposed by Bishop et al. in the limit in which the black holes are close to each other. We present an exact solution of the linearized initial value problem based on their proposal and make use of a recently introduced generalized formalism for studying perturbations of Schwarzschild black holes in arbitrary coordinates to perform the evolution. We clarify the meaning of the free parameters of the initial data family through the results for the radiated energy and waveforms from the black hole collision. © 2002 The American Physical Society.


Using Simple Marginal Analysis And Density Management Diagrams For Prescribing Density Management, Thomas J. Dean, S. Joseph Chang Jan 2002

Using Simple Marginal Analysis And Density Management Diagrams For Prescribing Density Management, Thomas J. Dean, S. Joseph Chang

Faculty Publications

This article presents a procedure to produce management regimes that not only maximize land value but also reflect stand development with simple marginal analyses of the accumulation and control of growing stock. An upper limit of growing stock is determined by translating management objectives into a future desired structure, and with this value as a guide for thinning age, marginal analysis is used to determine the planting density and the residual basal area after thinning. The procedure is demonstrated for a hypothetical loblolly pine plantation growing on land with a site index of 65 ft at 25 yr. The effects …


Raising Livestock In Resource-Poor Communities Of The North West Province Of South Africa - A Participatory Rural Appraisal Study, J. K. Getchell, A. F. Vatta, P. W. Motswatswe, R. C. Krecek, R. Moerane, A. N. Pell, T. W. Tucker, S. Leshomo Jan 2002

Raising Livestock In Resource-Poor Communities Of The North West Province Of South Africa - A Participatory Rural Appraisal Study, J. K. Getchell, A. F. Vatta, P. W. Motswatswe, R. C. Krecek, R. Moerane, A. N. Pell, T. W. Tucker, S. Leshomo

Faculty Publications

A participatory research model was used in six village communities in the Central Region of the North West Province of South Africa in order to achieve the following broad objectives: to obtain information on the challenges owners face in raising livestock in these areas and to evaluate the livestock owners' level of knowledge of internal parasites in their animals. Information obtained at participatory workshops clearly indicated a need for improvements in water supply, schools, job creation, and health services. Lack of pasture for grazing livestock was also cited as being important. Other most frequently mentioned livestock problems included 'gall sickness' …

Haemonchus Spp. In Sheep Farmed Under Resource-Poor Conditions In South-Africa - Effect On Haematocrit, Conjunctival Mucous Membrane Colour And Body Condition, A. F. Vatta, R. C. Krecek, M. J. Van Der Linde, P. W. Motswatswe, R. J. Grimbeek, E. F. Van Wijk, J. W. Hansen

Faculty Publications

A longitudinal study was conducted on the differential faecal egg counts, haematocrits and body condition scores of sheep belonging to resource-poor farmers at Rust de Winter, Gauteng province, and Kraaipan, North West Province, South Africa. The animals were scored for level of anaemia using the FAMACHA© method, an assay for the clinical evaluation of anaemia caused by Haemonchus spp. Periods of higher Haemonchus egg counts occurred from October to March for sheep at Rust de Winter and from September/October to February or April for sheep at Kraaipan. Lower haematocrit values were registered during these periods as was a higher incidence …


Preference Of Food Particle Size Among Several Urban Ant Species., Linda M. Hooper-Bùi, Arthur G. Appel, Michael K. Rust Jan 2002

Preference Of Food Particle Size Among Several Urban Ant Species., Linda M. Hooper-Bùi, Arthur G. Appel, Michael K. Rust

Faculty Publications

Appropriate particle size may be a critical characteristic for effective granular ant baits. We examined the particle size preference of six species of pest ants to an anchovy-based bait. We also examined head capsule widths of Argentine ants, Linepithema humile (Mayr) (mean = 0.54 mm), California harvester ants, Pogonomyrmex californicus (Buckley) (mean = 1.63 mm), red imported fire ants, Solenopsis invicta Buren (mean = 0.9 mm), and southern fire ants, Solenopsis xyloni McCook (mean = 0.76 mm) and compared them with the first and second most preferred particle size. There were differences between particle size of which the most mass …

Fa Composition Of Crude Oil Recovered From Catfish Viscera, Subramaniam Sathivel, Witoon Prinyawiwatkul, Casey C. Grimm, Joan M. King, Steven Lloyd

Faculty Publications

The FA composition of crude catfish oil recovered from whole viscera, digestive tract, liver, gallbladder, and visceral storage fat was determined and compared with that of fillet and nugget (abdominal portion). About 34% crude fat (wet basis) could be recovered from the whole catfish viscera. FA found in crude catfish visceral oil were C14:0, C16:0, C16:1, C18:0, C18:1, C18:2, C18:3, C20:0, C20:1, C20:2, C20:3, C20:4, and C22:6, the predominant FA being C18:1, C16:0, C18:2, and C18:0. Catfish visceral oil was characterized by a high level of unsaturated FA, which was similarly found in fillet and nugget. Total unsaturated FA in …


Semiparametric Maximum Likelihood Estimates Of Spatial Dependence, R. Kelley Pace, James P. Lesage Jan 2002

Semiparametric Maximum Likelihood Estimates Of Spatial Dependence, R. Kelley Pace, James P. Lesage

Faculty Publications

We semiparametrically model spatial dependence via a combination of simpler weight matrices (termed spatial basis matrices) and fit this model via maximum likelihood. Estimation of the model relies on the intuition that bounds to the log-determinant term in the log-likelihood can provide penalties to overfitting both the level and pattern of spatial dependence. By relying on symmetric and doubly stochastic spatial basis matrices that reflect different weight specifications assigned to neighboring observations, we are able to derive a mathematical expression for bounds on the log-determinant term that appears in the likelihood function. These bounds can be conveniently calculated allowing us …


Problem Patrons: All Shapes And Sizes, Kelly D. Blessinger Jan 2002

Problem Patrons: All Shapes And Sizes, Kelly D. Blessinger

Faculty Publications

Every type of library will inevitably have problem patrons, but this article focuses
mainly on public and academic libraries. As the times have changed, so has the magnitude of the problem patrons. Problems of the past seem irrelevant compared to some of the problems we are currently facing. Discussed in this article are particular types of problem behavior, including, but not limited to anger, harassment of staff, and homelessness. The types of each category include examples to illustrate each concern, and possible remedies.


Valley Floor Climate Observations From The Mcmurdo Dry Valleys, Antarctica, 1986-2000, Peter T. Doran, Christopher P. Mckay, Gary D. Clow, Gayle L. Dana, Andrew G. Fountain, Thomas Nylen, W. Berry Lyons Jan 2002

Valley Floor Climate Observations From The Mcmurdo Dry Valleys, Antarctica, 1986-2000, Peter T. Doran, Christopher P. Mckay, Gary D. Clow, Gayle L. Dana, Andrew G. Fountain, Thomas Nylen, W. Berry Lyons

Faculty Publications

Climate observations from the McMurdo dry valleys, East Antarctica are presented from a network of seven valley floor automatic meteorological stations during the period 1986 to 2000. Mean annual temperatures ranged from -14.8°C to -30.0°C, depending on the site and period of measurement. Mean annual relative humidity is generally highest near the coast. Mean annual wind speed increases with proximity to the polar plateau. Site-to-site variation in mean annual solar flux and PAR is due to exposure of each station and changes over time are likely related to changes in cloudiness. During the nonsummer months, strong katabatic winds are frequent …


Quantification Of The Spatial Gradient Of Local Volume Fraction From Tomography Images, Yongping Wang Jan 2002

Quantification Of The Spatial Gradient Of Local Volume Fraction From Tomography Images, Yongping Wang

LSU Master's Theses

Asphalt concrete has three constituents: aggregate, asphalt binder and air voids. In the mixture, aggregates serve as a skeleton of the mixture; asphalt serves as a binder to hold the aggregates together; and air voids prevent asphalt concrete from bleeding to avoid plastic mixes. The properties of asphalt concrete are controlled by the interaction of these three components. In asphalt concrete, asphalt binder, voids and aggregates are not uniformly distributed. The local volume fractions of these constituents vary with spatial locations. As a result, there exist a spatial gradient of the local volume fractions between two locations. Due to the …


One-Week Stability Of Forearm Venous Outflow As Assessed By Venous Occlusion Plethysmography, Jennifer Pitre Ortego Jan 2002

One-Week Stability Of Forearm Venous Outflow As Assessed By Venous Occlusion Plethysmography, Jennifer Pitre Ortego

LSU Master's Theses

The aim of this study was to test short-term and long-term reliability of venous outflow (VO) indices using the venous occlusion plethysmography technique. A secondary purpose was to compare venous measures to age, gender and various anthropometrical measures. The study group consisted of apparently healthy males and females, aged 18 to 80 years. Venous indices were under measures on two occasions (1 week apart), under the conditions of rest and following 5 min of upper arm occlusion. Venous outflow measures were calculated from the area under the curve (AUC) as well as the plethysmographic curve technique at the time .5 …


In The Dark Woods I Lost My Way, Debbie Kupinsky Jan 2002

In The Dark Woods I Lost My Way, Debbie Kupinsky

LSU Master's Theses

When I had journeyed half our life's way, I found myself in a shadowed forest. For I had Lost the path that does not stray Ah, it is hard to speak of what it was, That savage forest, dense and difficult, Which even in recall renews my fear: So bitter-death is hardly so severe! Dante Alegheri Inferno Canto 1 Dante's passage refers to the losing of a spiritual path, but for me it refers to the destruction of the past, memory and self. My work deals with the loss of the past and the burdens of memory. It deals with …


Wash, Karin Eberhardt Watts Jan 2002

Wash, Karin Eberhardt Watts

LSU Master's Theses

In this body of work, Wash, I translate the negative aspects of life in a positive, vibrant way. The physical and psychological sensations of life supply me with an intuitive frame of reference providing a point of departure for visual expression. Digital scanning and imaging techniques allow me to develop an immediate intimacy with the organic and inorganic objects, while I methodically examine, alter and reconfigure their forms. Graphic elements suggest symbolic interpretation from eastern studies and are sometimes enhanced with letterforms and photographic images representing the difficult articulation of thoughts. I synchronize this re-orchestration with the deciphering and close …


Transformation Of Paradise: Geographical Perspectives On Tourism Development On A Small Carribbean Island (Utila, Honduras), Frances Heyward Currin Jan 2002

Transformation Of Paradise: Geographical Perspectives On Tourism Development On A Small Carribbean Island (Utila, Honduras), Frances Heyward Currin

LSU Master's Theses

This thesis addresses the recent development of tourism on Utila, the westernmost island of the Bay Islands of Caribbean, Honduras. Especially during the 1990s, international tourists, mostly Europeans and North Americans, were attracted to the island because it was a relatively inexpensive place to dive on a beautiful fringing reef and to enjoy other benefits of a tropical beach community. Larger nearby islands, Roatán and Guanaja, had developed something of a tourism industry earlier. A review of the economic and culture history of Utila reveals that modern islanders -- English-speaking Anglo- and Afro-Caribbeans originally from the Cayman Islands were preadapted …


Surfactant-Induced Relative Permeability Modifications For Oil Recovery Enhancement, Subhash C. Ayirala Jan 2002

Surfactant-Induced Relative Permeability Modifications For Oil Recovery Enhancement, Subhash C. Ayirala

LSU Master's Theses

Surfactants have been considered for enhanced oil recovery by reduced oil-water interfacial tension. However, these surfactants may enhance oil recovery via wettability alteration as well. This study experimentally determines the influence of surfactant type and concentration on oil recovery, oil-water relative permeabilities and wettability in reservoir rocks. Several coreflood experiments were conducted using Yates reservoir fluids in Berea rocks and two types of surfactants (nonionic and anionic) in varying concentrations. A coreflood simulator was used to calculate oil-water relative permeabilities by history matching recovery and pressure drop measured during the corefloods. These relative permeability variations were interpreted using Craig's rules-of-thumb …

Decentralized And Adaptive Sensor Data Routing, Mengxia Zhu Jan 2002

Decentralized And Adaptive Sensor Data Routing, Mengxia Zhu

LSU Master's Theses

Wireless sensor network (WSN) has been attracting research efforts due to the rapidly increasing applications in military and civilian fields. An important issue in wireless sensor network is how to send information in an efficient and adaptive way. Information can be directly sent back to the base station or through a sequence of intermediate nodes. In the later case, it becomes the problem of routing. Current routing protocols can be categorized into two groups, namely table-drive (proactive) routing protocols and source-initiated on-demand (reactive) routing. For ad hoc wireless sensor network, routing protocols must deal with some unique constraints such as …


A Comparison Of Self-Report And Performance-Based Measures Of Physical Function In Older Adults, Amy Elizabeth Dunbar Jan 2002

LSU Master's Theses

The purpose of this thesis was to examine the associations between perceived quality of life (QOL)and self-report and performance-based measures of function. An additional purpose of this thesis was to determine whether the afore-mentioned tests could differentiate between independent-living and assisted-living older adults. A total of 36 residents, independent-living (n=22) and assisted-living (n=14), of a continuing care retirement community (age range=65-94) completed the study. Perceived QOL was assessed using the SF-36 and Nottingham Health Profile. The Barthel Index and Functional Status Index (FSI) were used to assess Activities of Daily Living (ADLs). Physical function was measured using the reduced Continuous …


Development Of A Phosphorus Management Model To Address Filamentous Algae In A Shallow, Subtropical, Urban Hypereutrophic Lake, Jennifer Eileen Ruley Jan 2002

Development Of A Phosphorus Management Model To Address Filamentous Algae In A Shallow, Subtropical, Urban Hypereutrophic Lake, Jennifer Eileen Ruley

LSU Master's Theses

City Park Lake is a shallow, subtropical, urban hypereutrophic lake located in Baton Rouge, Louisiana. By the late 1970’s, this artificial lake had experienced extreme eutrophication and suffered from frequent algal blooms and fish kills. Restoration of City Park Lake occurred in 1983 and consisted of dredging nutrient-laden sediments and the rehabilitation of sewage pipelines. Pre- and post-restoration water quality monitoring programs have provided valuable information by which to gage the long-term success of the restoration work. Following the restoration effort, dramatic improvements were observed in the lake including lower nitrogen, phosphorus and chlorophyll-a concentrations, reduced frequencies in algal blooms …
