Application Of Short-Term Sediment Dynamics And Particle-Bound Phosphorus Fractionation Methods (Sedex) To Estimate The Benthic Nutrient Loading Potential In Upper Newport Estuary, California, Hilary Amanda Collis Jan 2006

Application Of Short-Term Sediment Dynamics And Particle-Bound Phosphorus Fractionation Methods (Sedex) To Estimate The Benthic Nutrient Loading Potential In Upper Newport Estuary, California, Hilary Amanda Collis

LSU Master's Theses

Estuaries act as sources, sinks, and biogeochemical transformation sites for natural and anthropogenically-derived nutrients. Sediment loading from watersheds provides an important source of particulate nutrients to estuaries often neglected when constructing nutrient budgets. Deposition and resuspension of these sediments are known to impact biogeochemical cycles in estuarine environments. Phosphorus (P) exists in many forms in aquatic environments, and increased P loading to coastal environments increases primary productivity potentially leading to eutrophication. Magnitude and variability of sediment deposition, resuspension, and sediment-bound P concentrations were evaluated in Upper Newport Bay (UNB), California. During 2004, seven push cores were collected from the intertidal …

Evaluation Of The Effectiveness Of A Body Mass Index-For-Age Percentile Health Report In Raising Parent Awareness Of Their Child's Weight Status, Anantha Padmaja Lakkakula Jan 2006

Evaluation Of The Effectiveness Of A Body Mass Index-For-Age Percentile Health Report In Raising Parent Awareness Of Their Child's Weight Status, Anantha Padmaja Lakkakula

LSU Master's Theses

Overweight in children has become a major health concern. Research suggests that many parents may not be aware of their child’s actual weight status. The objectives of this study were to test the effectiveness of a body mass index (BMI)-for–age percentile report in raising parent awareness of their child’s weight status. Eighteen public elementary schools in southeast Louisiana were pair matched and divided into nine intervention and nine control schools. Children in the intervention and the control schools were divided into two groups 1) healthy weight (BMI ≥ 5th to <85th percentile) and 2) at risk and overweight (BMI ≥ 85th percentile). Forty children were randomly selected from each of the two weight groups from the intervention and the control schools. Parents of children in the intervention group received a BMI-for-age percentile health report along with a short questionnaire. Parents of children in control schools received the questionnaire only. Parents in the intervention group have 4.7 times more accurate perception about their child’s weight compared to the control group (OR: 4.7, 95% of CI: 0.89-24.86, p=0.00 ). After receiving the report, more parents of at risk or overweight children were concerned and only fewer parents of healthy weight children were anxious about their child’ weight. When parents were compared based on their child’s weight regardless whether they got the report, parents of at risk or overweight children were more than five times less likely to perceive the correct weight classification of their child (OR: 1.8, 95% of CI: 0.05-0.62, p=0.00) and less concerned about their child’s weight (OR: 0.98, 95% of CI: 0.32-2.93, p=0.00) when compared to parents of healthy weight children. All parents were willing to help their child follow healthy behaviors regard less of the report and their child’s weight status. A BMI-for-age percentile report appears to be an effective way to increase parent awareness and concern regarding their child’s weight status. With increased awareness, parents may be more likely to encourage their children to achieve a healthy weight.

Sensory Characteristics Of Salt Substitute Containing L-Arginine, Pamarin Waimaleongora-Ek Jan 2006

Sensory Characteristics Of Salt Substitute Containing L-Arginine, Pamarin Waimaleongora-Ek

LSU Master's Theses

Dietary salt restriction is a common approach recommended by physicians in the treatment and prevention of hypertension. Salt substitute is a potential alternative. The most popular salt substitute is KCl, having similar physical properties to NaCl. Because of the higher molecular weight of cations (K+), KCl imparts undesired bitterness and metallic aftertaste. L-arginine has been found to have the bitterness-suppression property. Therefore, it may be used in the mixture of salt substitutes. In the first study, NaCl and four salt substitute solutions consisting of KCl, NaCl, and L-arginine, were developed at 0.5%, 1%, and 1.5% w/v. A discriminative test was …

Background Conglomerates In Alkan's Quasi-Faust, Op. 33, No. 2, Matthew James Steinbron Jan 2006

Background Conglomerates In Alkan's Quasi-Faust, Op. 33, No. 2, Matthew James Steinbron

LSU Master's Theses

Various approaches have been used over the past 50 years to describe and analyze works that exhibit tonality but have more than one tonic. This paper focuses solely on a subcategory of such works: those that begin in one key and end in another, the first key being permanently replaced by the second. The most prominent systems of terminology and analysis for such works include “progressive tonality,” “directional tonality,” “interlocking structures,” and “background conglomerates.” After examining these systems, “background conglomerates” is determined to best suit works that permanently change tonics. This approach, which was introduced by Harald Krebs, employs a …

Design Of Linear Boolean Network Codes For Combination Networks, Shoupei Li

LSU Master's Theses

Network coding is a promising technique to improve the throughput of communication networks. In the thesis, we investigate linear Boolean network codes on a special class of multicast networks, called combination networks. Using companion matrices of primitive polynomials over finite fields, we design a class of symmetric linear Boolean network codes from Reed-Solomon codes for single-source combination networks. We also prove that, for some cases, the linear Boolean network codes are optimal in the sense of minimum network uses. In the thesis, we further consider two-source network coding problem for combination networks and other specific networks. We develop a method …

Mothers Grimm And Other House Held Tales, Holly Kay Streekstra Jan 2006

Mothers Grimm And Other House Held Tales, Holly Kay Streekstra

LSU Master's Theses

Mothers Grimm and Other House Held Tales is a body of work that uses fairy tale archetypes and narrative traditions to comment upon tensions and conflicts in sexual self-understanding. This is achieved through a reflection on attitudes that women adopt regarding their own sexuality. Such a reflection is instigated through a presentation of prominent cultural archetypes that exist, no longer as received ideas, but as a bold and entertaining expression of how sex can change our attitude towards those ideas that we often take for granted. Through an assemblage of objects and video, this body of work evokes a domestic …

The Antipodes: On Rebellion, Michael Scott Robinson Jan 2006

The Antipodes: On Rebellion, Michael Scott Robinson

LSU Master's Theses

This essay argues that the term rebellion applies to two similar but distinguishable experiences representative of the limits to human action and capacity. The political rebel is a man who rebels against an oppressive political regime. Opposing him is the metaphysical rebel whose action is inspired by a grievance against the nature of existence generally, as a human being, which he has interpreted to be oppressive. These contradicting inspirations are matched by juxtaposing consequences, exemplified through a literary analysis of Fyodor Dostoevsky’s novels, and a historical analysis of Václav Havel and the Velvet Revolution.

Muscovite Pseudomorphs After Staurolite As A Record Of Fluid Infiltration During Prograde Metamorphism, Jennifer Kaye Whittington Jan 2006

Muscovite Pseudomorphs After Staurolite As A Record Of Fluid Infiltration During Prograde Metamorphism, Jennifer Kaye Whittington

LSU Master's Theses

Pressure-temperature conditions encountered by metamorphic rocks are often used to constrain tectonic environments of formation. Evidence of the prograde path during metamorphism is often obliterated by peak metamorphic conditions. However, pseudomorphs that form during prograde metamorphism may provide insights into heat and mass transport along this portion of the P-T-X-t path. Seventeen sillimanite zone samples, each containing 2-5 muscovite-rich pseudomorphs after staurolite, were investigated from pelitic schists of the Farmington Quadrangle, west-central Maine, USA. Pseudomorphs are easily recognized by an increase in average grain size (~cm) and change to randomly oriented muscovite-rich (~45-75%) modal mineralogy relative to the rock matrix …

Phytoremediation Of A High Phosphorus Soil By Summer And Winter Hay Harvest, Veronica A. Ryan Jan 2006

Phytoremediation Of A High Phosphorus Soil By Summer And Winter Hay Harvest, Veronica A. Ryan

LSU Master's Theses

Phosphorus (P) loading into surface water from runoff and subsurface flow leaving soils subjected to long-term applications of poultry litter (PL) will degrade water quality. A practical way to reduce such loading is to remove soil P through plant uptake and harvest removal. The primary field study presented here examined the effectiveness of hay harvest utilizing a double-cropped system - perennial warm-season forage grass, common bermudagrass (CB; Cynodon dactylon (L.) Pers.), overseeded with annual ryegrass (ARG; Lolium multiflorum Lam.), a cool-season forage, in reducing soil P from a Ruston fine-sandy loam impacted by PL amendments. A secondary field study similarly …

The Business Dynamics In Telecommunication Market Consolidation, George Amstad Jan 2006

The Business Dynamics In Telecommunication Market Consolidation, George Amstad

LSU Master's Theses

The Swiss telecommunication market is quite different from the markets in surrounding European countries. The Swiss Market is characterized by a very small number of competitors and relatively high and stable prices. The model in this thesis explains shows how the limited competition enables the mobile telecommunication service providers to keep prices up. This is due to a oligopoly market situation linked to complicated laws that discourage new competitors to join the Swiss market. Later in 2006, the Swiss federal council will pass the new televisor law, which will make it significantly easier to join the Swiss market. This will …

Dendrochronological Analysis Of Productivity And Hydrology In Two Louisiana Swamps, John Blake Amos Jan 2006

Dendrochronological Analysis Of Productivity And Hydrology In Two Louisiana Swamps, John Blake Amos

LSU Master's Theses

Modified river flows and land subsidence have subjected many coastal swamp forests in the delta of the Mississippi River to greatly altered flooding, sediment, and nutrient regimes. These areas have become inundated to greater depth, duration, and frequency and either are connected to the river and receive drastically increased sediment and nutrients (riverine swamps) or have become disconnected from riverine flooding (stagnant swamps) and receive little or no sediment and nutrient input. To better understand how these changes are affecting ecosystems, dendrochronological techniques for baldcypress (Taxodium distichum L. Rich.) were used at three sites in each of two contrasting swamps …

Compiler Assisted Cache Prefetch Using Procedure Call Hierarchy, Sheela A. Doshi Jan 2006

Compiler Assisted Cache Prefetch Using Procedure Call Hierarchy, Sheela A. Doshi

LSU Master's Theses

Microprocessor performance has been increasing at an exponential rate while memory system performance improved at a linear rate. This widening difference in performances is increasingly rendering advances in computer architecture less useful as more instructions spend more time waiting for data to be fetched from the memory after a cache miss. Data prefetching is a technique that avoids some cache misses by bringing data into the cache before it is actually needed. Different approaches to data prefetching have been developed, however existing prefetch schemes do not eliminate all cache misses and even with smaller cache miss ratio, miss latency remains …
