Essences And Transformations In Objects, Animals, And Humans, Alicia Brooke Smith Dec 2010

Essences And Transformations In Objects, Animals, And Humans, Alicia Brooke Smith

Masters Theses & Specialist Projects

Research as to how humans group natural kinds, such as animals, is essential to understanding categorization processes. However, it lacks conventional application and generalization to everyday life. Humans are social beings that encounter a wide array of individuals on a daily basis. In these situations, we are required to consider various properties that make up these people. As Keller (2005) suggests, the way we categorize is shaped by our theories about the world. Therefore, when we determine the rationale behind people’s social categorization processes, we are better able to understand people’s perceptions of their social environment. Moreover, when we conduct …


Appearance Based Stage Recognition Of Drosophila Embryos, Gopi Chand Nutakki Dec 2010

Appearance Based Stage Recognition Of Drosophila Embryos, Gopi Chand Nutakki

Masters Theses & Specialist Projects

Stages in Drosophila development denote the time after fertilization at which certain specific events occur in the developmental cycle. Stage information of a host embryo, as well as spatial information of a gene expression region is indispensable input for the discovery of the pattern of gene-gene interaction. Manual labeling of stages is becoming a bottleneck under the circumstance of high throughput embryo images. Automatic recognition based on the appearances of embryos is becoming a more desirable scheme. This problem, however, is very challenging due to severe variations of illumination and gene expressions. In this research thesis, we propose an appearance …

The Hydrology Of The Carroll Cave-Toronto Springs System: Identifying And Examining Source Mixing Through Dye Tracing, Geochemical Monitoring, Seepage Runs, And Statistical Methods, Benjamin Verlinden Miller

Masters Theses & Specialist Projects

In karst areas relationships between activities occurring on the surface and the overall health of the subsurface environment are often highly interconnected. However, the complex nature of karst flow systems can often make identification of these connections difficult. Carroll Cave, a large stream cave system located in the central Missouri Ozarks, is known for its biological and speleological significance. A dye tracing project to delineate a Carroll Cave recharge area through dye tracing has identified an area of 18.5 km2 which contributes water to the cave. The water from Thunder River within Carroll Cave was positively traced to eight springs …


Analysis Of The Clear Plaque Phenotype Of The Bacteriophage Hk75, Phani Chandrika Kunapuli Dec 2010

Analysis Of The Clear Plaque Phenotype Of The Bacteriophage Hk75, Phani Chandrika Kunapuli

Masters Theses & Specialist Projects

The growth of bacteriophage HK75 is inhibited by specific mutations in the zinc binding domain of the host RNA polymerase beta prime subunit. It shares this rare property with bacteriophage HK022 and other phages that use RNA mediated antitermination to promote early gene expression. Recent genomic analysis of HK75 and HK022 has confirmed the relatedness of these two phages and place HK75 in the lambdoid family of bacteriophages. Lambdoid phages are temperate and can adopt a lytic or lysogenic lifestyle upon infection of a suitable host. However, HK75 only forms clear plaques and thus appears to be defective in its …


Differentiating Anxiety And Depression Using The Clinical Assessment Of Depression, Zane K. Dempsey Dec 2010

Differentiating Anxiety And Depression Using The Clinical Assessment Of Depression, Zane K. Dempsey

Masters Theses & Specialist Projects

Anxiety and depression are two disorders frequently diagnosed in adults. Given serious adverse affects such as physical health problems, interpersonal relationship difficulties, and suicide, differentiation in treatment of these often comorbid disorders is a necessity in providing appropriate care. The tripartite model of anxiety and depression (Clark & Watson, 1991) proposes that these disorders are linked by a common trait (Negative Affect) and differentiated by a trait common to depression (lack of Positive Affect) and a trait common to anxiety (Physiological Hyperarousal). The Clinical Assessment of Depression (CAD; Bracken & Howell, 2004), a recently published selfreport narrow-band measure of depression, …

Impact Of Stress Management On Learning In A Classroom Setting, Pankaj Mandale

Masters Theses & Specialist Projects

Stress is an important feature of the lives of college students and can impact negatively on learning. The effectiveness of an in-class stress management intervention for improving course content retention was tested with a cross-over design in two introductory graduate biostatistics classes. Each class met one day per week for the duration of the semester, and was taught by the same instructor, following the same syllabus. A pretest duplicating items on the midterm and final exam was administered to all students at the first class meeting. Identical midterm and final exams were administered in both classes. During the first half …


Investigation Of Volatile Products From Wood Pyrolysis, Prabhavathi Gade Dec 2010

Investigation Of Volatile Products From Wood Pyrolysis, Prabhavathi Gade

Masters Theses & Specialist Projects

In this research we are following the thermo-chemical degradation of wood in the absence of oxygen. The objectives are to evaluate the influence of heating rates on pyrolysis products obtained from wood pyrolysis and to evaluate the influence of acid pre-treatment on pyrolysis products. Depending on the wood heating rates, pyrolysis can be categorized as Flash pyrolysis, Fast pyrolysis, and Slow pyrolysis. We have evaluated the volatile products obtained at different heating rates and the volatile products obtained from sulfuric acid pre-treatment by using gas chromatography- mass spectrometry (GC-MS). We have also performed thermo-gravimetric analysis (TGA) of raw wood samples …


An Application And Refinement Of The Karst Disturbance Index Through Evaluating Variability In Island Karst Disturbance In Puerto Rico, Brandon Lee Porter Dec 2010

An Application And Refinement Of The Karst Disturbance Index Through Evaluating Variability In Island Karst Disturbance In Puerto Rico, Brandon Lee Porter

Masters Theses & Specialist Projects

Karst environments are unique landscapes that contain important resources, including freshwater aquifers and specialized ecosystems, which are easily disturbed due to the interconnected nature of the surface and subsurface. The anthropogenic impacts on karst are deleterious to the ecosystems that are dependent on the karst environment and also to groundwater supplies. The Karst Disturbance Index (KDI) is a holistic tool used to measure anthropogenic impacts associated with karst environments, which has been applied and refined through studies performed in Florida and Italy, yet still remains untested and susceptible to modification for other areas. Application of the KDI in Arecibo, Puerto …

What Brown Saw And You Can Too, Philip Pearle, Brian Collett, Kenneth Bart, David Bilderback, Dara Newman, D. Scott Samuels

Biological Sciences Faculty Publications

A discussion of Robert Brown’s original observations of particles ejected by pollen of the plant Clarkia pulchella undergoing what is now called Brownian motion is given. We consider the nature of those particles and how he misinterpreted the Airy disk of the smallest particles to be universal organic building blocks. Relevant qualitative and quantitative investigations with a modern microscope and with a “homemade” single lens microscope similar to Brown’s are presented.

A Little Bat And A Big City: Nocturnal Behavior Of The Tricolored Bat (Perimyotis Subflavus) Near Indianapolis Airport, Jared Scot Helms

All-Inclusive List of Electronic Theses and Dissertations

I captured 16 Perimyotis subflavus on property owned by the Indianapolis International Airport, of those 16 animals I obtained roosting data on all 16 and foraging data on 11 individuals. The goal of this project was to see if a short broad winged bat’s foraging and roosting habits were affected by the fragmentation of habitat due to rapid urbanization. Using radio telemetry to find roosts and to create multi-azimuth triangulation I was able to create data points and place them onto a habitat map inside ArcGIS software. Sampling the size of woodlots available to the bats I was able to …


A New Troodontid Theropod Dinosaur From The Lower Cretaceous Of Utah, Phil Senter, James I. Kirkland, John Bird, Jeff A. Bartlett Dec 2010

A New Troodontid Theropod Dinosaur From The Lower Cretaceous Of Utah, Phil Senter, James I. Kirkland, John Bird, Jeff A. Bartlett

College of Health, Science, and Technology

Background: The theropod dinosaur family Troodontidae is known from the Upper Jurassic, Lower Cretaceous, and Upper Cretaceous of Asia and from the Upper Jurassic and Upper Cretaceous of North America. Before now no undisputed troodontids from North America have been reported from the Early Cretaceous. Methodology/Principal Findings: Herein we describe a theropod maxilla from the Lower Cretaceous Cedar Mountain Formation of Utah and perform a phylogenetic analysis to determine its phylogenetic position. The specimen is distinctive enough to assign to a new genus and species, Geminiraptor suarezarum. Phylogenetic analysis places G. suarezarum within Troodontidae in an unresolved polytomy with Mei, …


Olfactory Mate Choice And Potential Chemical Signals Of The White-Throated Sparrow (Zonotrichia Albicollis), Peter Sebastian Dec 2010

Olfactory Mate Choice And Potential Chemical Signals Of The White-Throated Sparrow (Zonotrichia Albicollis), Peter Sebastian

All-Inclusive List of Electronic Theses and Dissertations

Chemical odor signals are well documented in mammals, and yet almost nothing is known about the use of chemical odor signals in birds due to the traditional view that birds have a no sense or a poor sense of smell. Recent studies have revealed the traditional view to be unfounded, but more work is necessary to 1) expand our knowledge of avian olfaction in passerine species and 2) determine whether birds utilize chemical signals. The aim of this thesis was to 1) test for olfactory-based choice in a passerine species, and examine the chemical composition of preen oil for potential …

Development And Characterization Of Shock Tubes For Laboratory Scale Blast Wave Simulation, Aaron D. Holmberg Dec 2010

Development And Characterization Of Shock Tubes For Laboratory Scale Blast Wave Simulation, Aaron D. Holmberg

Department of Engineering Mechanics: Dissertations, Theses, and Student Research

The prevalence of traumatic brain injury (TBI) in American soldiers exposed to a blast wave has created an urgent need to better understand the effects of blast wave insult to the head. Developing techniques that can experimentally simulate well controlled blast waves in a laboratory environment is a critical component of the research efforts towards this goal. For this work, a 4-in. cylindrical uniform shock tube and a nonuniform shock tube combining a 4-in. cylindrical gas driver with a 9-in. square driven section have been developed. The hosting laboratory, gas handling system, multichannel data acquisition systems, and the related network …


In Silico Modeling Of Ph-Optimum Of Protein-Protein Binding, Rooplekha C. Mitra, Zhe Zhang, Emil Alexov Dec 2010

In Silico Modeling Of Ph-Optimum Of Protein-Protein Binding, Rooplekha C. Mitra, Zhe Zhang, Emil Alexov

Publications

Protein-protein association is a pH-dependent process and thus the binding affinity depends on the local pH. In vivo the association occurs in a particular cellular compartment, where the individual monomers are supposed to meet and form a complex. Since the monomers and the complex exist in the same micro environment, it is plausible that they coevolved toward its properties, in particular, toward the characteristic subcellular pH. Here we show that the pH at which the monomers are most stable (pH-optimum) or the pH at which stability is almost pH-independent (pH-flat) of monomers are correlated with the pH-optimum of maximal affinity …

Geosciences and Geological and Petroleum Engineering Faculty Research & Creative Works

Laboratory studies reveal the sensitivity of measured geophysical properties to solid-fluid, fluid-fluid, and solid-solid interfaces in granular and fractured materials. In granular materials, electrical properties and nuclear magnetic resonance relaxation times exhibit a strong dependence on the size and properties of the solid-fluid interface. The electrical and seismic properties of granular materials and the seismic properties of fractured materials reveal a dependence on the size or geometry of fluid-fluid interfaces. Seismic properties of granular and fractured materials are affected by the effective stress and cementing material at solid-solid interfaces. There have been some recent studies demonstrating the use of field-scale …


The River Discontinuum: Applying Beaver Modifications To Baseline Conditions For Restoration Of Forested Headwaters, Denise Burchsted, Melinda Daniels, Robert Thorson, Jason Vokoun Dec 2010

The River Discontinuum: Applying Beaver Modifications To Baseline Conditions For Restoration Of Forested Headwaters, Denise Burchsted, Melinda Daniels, Robert Thorson, Jason Vokoun

Center for Integrative Geosciences

Billions of dollars are being spent in the United States to restore rivers to a desired, yet often unknown, reference condition. In lieu of a known reference, practitioners typically assume the paradigm of a connected watercourse. Geological and ecological processes, however, create patchy and discontinuous fluvial systems. One of these processes, dam building by North American beavers (Castor canadensis), generated discontinuities throughout precolonial river systems of northern North America. Under modern conditions, beaver dams create dynamic sequences of ponds and wet meadows among free-flowing segments. One beaver impoundment alone can exceed 1000 meters along the river, flood the valley laterally, …

Donald Sutherland: The Politics And Erotics Of Submission, Jean Walton

English and Creative Writing Faculty Publications

When Donald Sutherland burst onto the American film scene with his portrayal of Hawkeye in the unexpected Robert Altman hit M*A* S*H (1970), the popular press couldn't seem to agree on how best to characterize this new "un-Hollywood" star, fixing by turns on his Canadian background, his political activism, or his "funny peculiar" sense of humor (Dorothy Manners, "Sutherland - 'Actors Should Be Involved in Pertinent Causes,'" L.A. Examiner Sunday, 12 July 1970, n.p.; Douglas Marshall, "The Funniest Film Actor Canada Has Ever Produced," Maclean's, 1 September 1970, 42). After the release a few months later of Kelly's Heroes (1970), …

Nanocrystalline Piezoresistive Polysilicon Film Obtained By Aluminum Induced Crystallization For Pressure Sensing Applications, Suraj Kumar Patil Dec 2010

Nanocrystalline Piezoresistive Polysilicon Film Obtained By Aluminum Induced Crystallization For Pressure Sensing Applications, Suraj Kumar Patil

Material Science and Engineering Dissertations - Archive

The overall objective of our research was to integrate various sensors on to a single flexible substrate for multi-sensory information gathering. Additional capabilities could be incorporated towards the realization of 'smart skin' for simultaneous and real time sensing of various mechanical, biological and chemical stimuli. Recent research venues are dictated by the trend of shifting from conventional silicon (Si) substrates to lower weight, low profile, structurally robust and lower cost flexible substrates. These flexible substrates easily conform to non-planar objects, could be batch fabricated at lower cost and enable multilayer construction. This would eventually evolve into seamless assimilation of sensors …


Generation Of Conformation Sensor Recombinant Antibodies To Understand Redox Regulation Of Ptp1b, Aftabul Haque Dec 2010

Generation Of Conformation Sensor Recombinant Antibodies To Understand Redox Regulation Of Ptp1b, Aftabul Haque

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

Protein tyrosine phosphatase 1B (PTP1B) plays important roles in down-regulation of insulin signaling. Although it has been established as a potential therapeutic target for the treatment of diabetes and obesity, the finding of pharmaceutically acceptable inhibitors remains challenging. PTP1B is regulated by reactive oxygen species (ROS) produced in response to insulin. The reversibly oxidized form of this enzyme (PTP1B-OX) is inhibited and undergoes profound conformational changes at the active site. We hypothesized that a conformation-sensor antibody that recognizes PTP1B-OX may stabilize the inactive state and inhibit phosphatase activity. We isolated PTP1B-OX-specific single chain variable fragments (scFvs) from an antibody phage …
