Phytoplankton growth model for a turbid pulsed aquatic ecosystem.

Umorin, Mikhail Pavlovich.

The objective of this study was to develop a computer simulation that successfully predicted chlorophyll-a dynamics in Lake Waco. A small-scale batch culture was used to elucidate intrinsic growth rate and how it was ...
Periphyton-nutrient dynamics in a gradient-dominated freshwater marsh ecosystem.

Scott, J. Thad (Jefferson Thad). (Wilmington, N.C : Society of Wetland ScientistsOldendorf/Luhe, Germany : Inter-Research, )

In this study, the factors influencing the development of a nutrient availability gradient in a wetland ecosystem and the subsequent controls to, and feedbacks from, the structure and function of the periphyton community ...
Existence of positive solutions to singular right focal boundary value problems.

Maroun, Mariette. (Orlando, FL : International Publications., )

In this dissetation, we seek positive solutions for the n^th order ordinary differential equation, y^(n)=f(x,y), satisfying the right focal boundary conditions, y^(i)(0)=y^(n-2)(p)=y^(n-1)(1)=0, i=0,...,n-3, where p is a ...
The response of riparian vegetation to PL-566 flood control structures.

Duke, Jacquelyn R. (Baylor University, )

In this study, the response of riparian trees to increased stream water availability due to hydrologic alteration by PL-566 dams was investigated through three successive studies. To determine site water balance within a ...
High-performance liquid chromatographic methods for quantitative assessment of degradation products and extractives in pretreated lignocellulose.

Chen, Shou-Feng. (Amsterdam : Elsevier B. V.Washington, D.C. : American Chemical Society., )

Long-term economic, national security, and environmental concerns have motivated research into renewable fuels from lignocellulosic biomass. Among energy alternatives, biomass-derived ethanol represents one of the more ...
Between reality and mystery: food as fact and symbol in plays by Ibsen and Churchill.

Pocock, Stephanie J.

In Henrik Ibsen's and Caryl Churchill's plays, food is both fact and symbol, a reminder of both the shared physicality of the actors and spectators and of an equally powerful human desire for symbolic significance. This ...
Reading Dreams: An Audience-Critical Approach to the Dreams in the Gospel of Matthew

Dodson, Derek S. (Perspectives in Religious Studies., )

This dissertation seeks to read the dreams in the Gospel of Matthew (1:18b-25; 2:12, 13-15, 19-21, 22; 27:19) as the authorial audience. This approach requires an understanding of the social and literary character of ...
Virtues, divine commands, and the debt of creation: towards a Kierkegaardian Christian ethic.

Manis, R. Zachary (Robert Zachary). (Southwestern Philosophical Society, )

Though Kierkegaard's ethic in "Works of Love" frequently has been a target of harsh — and often uncharitable — criticism, a number of recent treatments have sought to defend both its viability and its relevance to the ...
Evolving a Disjunctive Predator Prey Swarm using PSO: Adapting Swarms with Swarms

Riyaz, Firasath

Swarm Intelligence is the study of "the emergent collective intelligence of groups of simple agents." Recent research has explored the important applications in the field of business, telecommunications, robotics and ...
Unique fragmentation of pentafluorobenzylic alcohols and the use of modified injection port liners in the gas chromatographic-based screening for catalytic activity.

Fisher, Henry C.

An unprecedented reaction, the base-catalyzed fragmentation of pentafluorobenzylic alcohols, was investigated. Studies on a variety of C6F5-derived alcohols show that a dual reaction pathway occurs in mixed solvent systems ...
Effects of hind limb unweighting on the expression of physiological markers of muscle atrophy and myofibrillar protein content in the soleus and extensor digitorum longus of Sprague-Dawley rats.

Vacanti, Anthony J.

The purpose of this study was to determine the effects of hind limb unweighting on the expression of physiological markers of muscle atrophy and myofibrillar protein content in the soleus (SOL) and extensor digitorum ...
Relationship between self-efficacy beliefs and socio-cultural adjustment of international graduate students and American graduate students.

Gajdzik, Patrycja K.

There are many benefits to the presence of international students on American campuses such as increase in diversity and economic contribution (AEC, 2000). However, many international students struggle with adjusting to ...
Do actors or observers make better eyewitnesses?

Colby, M. Amanda Earl.

Researchers studying the reliability of eyewitness testimony have focused mainly on criminal rather than civil cases, specifically those including product identification and liability. With numerous lawsuits against product ...
The affects of a middle grades teacher education program on preservice teachers choice of teaching strategies and mathematical understanding.

Eddy, Colleen M.

This study investigated how mathematical knowledge, mathematics pedagogy, and knowledge of students' understanding in mathematics impacted middle grades preservice mathematics teachers' lesson planning and teaching strategies ...
The Accelerated Reader program and students' attitude towards reading.

Focarile, Deborah Ann.

This study explores the relationship between the use of the Accelerated Reader Program, a computerized reading management program marketed by Advantage Learning Systems, Inc., and student's attitudes towards reading while ...
The recombinant expression of two pollen allergens using plant-viral and yeast expression systems.

Moehnke, Marcie H.

Allergic disease causes much distress within industrialized areas of the world, affecting approximately a quarter of the population in such areas. Current immunotherapy involves the administration of increasing concentrations ...
Multigenerational responses of Daphnia magna to Ethynylestradiol and Faslodex.

Clubbs, Rebekah L.

Select environmental contaminants can disrupt normal functions of aquatic invertebrate endocrine systems. While ecological risk assessments often rely on standardized laboratory toxicity tests to assess ecological impacts, ...
Data compression application to the MIL-STD 1553 avionics data bus.

Weston, Bron O.

With the current state of legacy military avionic systems reaching its ceiling in memory space, processing power, and data-bus through-put (bandwidth), a need has arisen to maximize its limited resources to avoid extensive ...
Java bytecode compilation for high-performance, platform-independent logical inference.

Arte, Ashish.

Automated reasoning systems are powerful computer programs capable of solving complex problems. They are characterized as computationally intensive having high performance requirements. Very few reasoning systems have ...
The influence of load on kinematics of computer-simulated sagittal-plane lifting.

Newman, Patrick S.

Researchers have shown that lifting kinematics change predictably with increased load. To test whether these kinematics patterns are intrinsic or voluntary, a computer model was developed to simulate lifting in the sagittal ...
