Evaporation Estimation Using A Floating Pan, Michael Klink

All Theses

Almost all regions in the United States must accurately estimate evaporation to have effective water management programs. The purpose of this study is to develop a better method for measuring evaporation. Lake evaporation along with meteorological data are measured directly from a floating pan. The floating pan is specifically designed to account for one of the most sensitive parameters of evaporation, the water surface temperature, which the design achieves. However, other design factors such as air movement, solar radiation, stability, heat transfer, wave action, water level range, and site location were also taken into consideration. The evaporation measured from the …

Brain Stimulation Reward Is Integrated By A Network Of Electrically-Coupled Gaba Neurons, Matthew Brian Lassen

Theses and Dissertations

Although it is well-established that animals will self-stimulate electric current to various diverse brain structures, the neural substrate of brain stimulation reward (BSR) has eluded identification since its discovery more than a half-century ago. We show that GABA neurons in the midbrain, hypothalamus and thalamus express connexin-36 (Cx36) gap junctions and couple electrically with dopamine application or by stimulation of the internal capsule (IC), which also supports self-stimulation. The threshold for responding for self-stimulation of the IC is the threshold for coupling between these GABA neurons, the degree of responding for IC ICSS is proportional to the magnitude of electrical …

Hindsight: The Moving Image And The Post-Photographic, John Aäsp

Theses

My recent video work employs a chronophotographic template to play on the idea of extracting knowledge from a fragmented visual sequence. Rather than freezing separate frames as instances of motion (as seen in a Muybridge sequence), motion is left within the sequence—looping continuously to create a paradox of stasis and dynamism. Using found footage from an older film era or clips from modern television, sequences are recaptured and reorganized to create a media-hybridized moment standing in a new temporal flow.

Influenced by the philosophy of Henri Bergson, this work explores a gray area between cinema and photography, motion and stillness, …

The Molecular And Ecophysiological Roles Of Rubisco Activase And Rubisco Activase Likes In Photosynthetic Thermal Regulation Of Acer Rubrum And Arabidopsis Thaliana , David Weston

All Dissertations

Determining the consequences of human impact on our current and future climate is proving to be to be one of the greater challenges in modern biology. Current global models employing coupled atmosphere and terrestrial carbon feedbacks range in their predictions from the inconsequential to that of vast food shortages and species extinctions. However, there is hope that the emergence of new molecular approaches will revolutionize our understanding of plant and animal responses to a changing environment, allowing for higher predictive power when scaling up from the level of the individual to ecosystem-scale processes. This dissertation is an initial attempt for …

Stabilization Of Vascular Elastin By Treatment With Tannins, Jason Isenburg

All Dissertations

Elastin is an important component of the extracellular matrix that endows cardiovascular tissue with the ability to extend and recoil repetitively. It has been shown that elastin may be vulnerable to enzymatic degradation and calcification in certain pathological cases. As a result, elastin degeneration may be associated with the failure of tissue-derived cardiovascular devices, such as bioprosthetic heart valves, as well as the development and progression of aortic aneurysms, a disease associated with progressive connective tissue degeneration of the arterial wall. Therefore, an elastin stabilizing agent may be beneficial for both applications. As such, our objectives for elastin stabilization are …

Nomos, Conflict, And The Tragedy Of Adjudication: The Jurisprudence Of Robert Cover, Julen Etxabe

ExpressO

Robert Cover is known for having argued that in every plural society there exist, along with the State, multiple normative entities that create and maintain their own sense of normativity, that is, their own holistic modes of assessing good and bad, valid and invalid, right and wrong. Beyond that, few systematic attempts have been made to pursue this view as a comprehensive theory of law. The principal aim of this piece is to demonstrate that Cover offers a novel and viable paradigm of law, which must at least include an ontology (an understanding of the basic units and organizational structure …

Identifying Economic Indicators For Ecosystem-Based Management:, Scott Norris

Publications

In America and across the world, the use of ecosystem-based management is

increasing. One of the primary challenges faced in using this method of management is the integration of economic data and environmental information. This report explores the use of a new tool for integrating economic data, ecosystem-based economic indicators, in a case study of Elkhorn Slough National Estuarine Research Reserve, an estuarine environment located in Monterey County, CA. Research and literature reviews were used to detail the economic activities of the area, in order to identify possible indicators,criteria for evaluating the indicators, and potential sources of indicator data. After …

2d Arbitrary Lagrangian-Eulerian (Ale) Model Of Blood Flow In The Left Ventricle Of The Heart / Zati Hakim Azizul Hasan, Azizul Hasan Zati Hakim

Student Works (2000-2009)

This research is a study of the dynamics of the heart valves and the blood using numerical computational technique. This numerical technique is known as the Arbitrary Lagrangian-Eulerian (ALE) and is introduced in a finite element environment. By means of a mesh movement method, the ALE uses separate sets of reference systems to study the fluid-structure interaction of the heart. The fluid domain is most conveniently described with respect to an Eulerian reference frame while a Lagrangian formulation is more appropriate for the structure domain. Due to the incompatibility factor of the two reference frames, coupling of the reference systems …

Collisions Of Red-Tailed Hawks (Buteo Jamaicensis), Turkey Vultures (Cathartes Aura), And Black Vultures (Coragyps Atratus) With Aircraft: Implications For Bird Strike Reduction, Bradley F. Blackwell, Sandra E. Wright

United States Department of Agriculture Wildlife Services: Staff Publications

From 1990 through 2003, 52,493 wildlife collisions with aircraft were reported to the U.S. Federal Aviation Administration (FAA); 97% of these incidents involved birds. The approximate cost to the civil aviation industry in the U.S.A. due to collisions of birds with aircraft (hereafter referred to as bird strikes) was $163.51 million in direct monetary losses and associated costs for the 14 year period (Cleary et al. 2004). Strikes with raptors (Falconidae and Accipitridae; including vultures, Cathartidae)accounted for approximately 28% of reported aircraft down time resulting from known-species bird strikes (known species =182942 hr; total for all birds = 244510 hr) …

The Role Of Natural And Sexual Selection In The Origin And Maintenance Of Divergence Within And Between The Mexican Sailfin Mollies, Poecilia Velifera And P. Petenensis, Shala Hankison

All Dissertations

Understanding speciation remains a holy grail of evolutionary biology. One useful approach is studying the evolutionary mechanisms important in population divergence to infer the mechanisms important in speciation. This method is especially useful when closely related species can be compared to determine whether intraspecific differences parallel interspecific differences. I studied population divergence in two species of Mexican sailfin mollies, Poecilia velifera and P. petenensis. These closely related species are particularly useful for this type of study, as they live in habitats that may differ in the importance of natural selection. In addition, these species may differ in the importance …

Impact Of Wastewater Reuse In Burlington County On Surface Water Quality And Adjacent Wetlands, Crystal L. Mattson

Grab water samples were collected from three (3) ponds located on the golf course over the course of a year and were analyzed for nitrate-nitrogen, total phosphorus, organics, and bacteria. A second golf course, Medford Lakes Country Club is currently irrigated with groundwater. Grab water samples were collected from both locations and analyzed for nutrients and bacteria for comparison purposes.

Results of sample analyses indicate that detriment to the quality of surface water at the …

Evidence That Talin Alternative Splice Variants From Ciona Intestinalis Have Different Roles In Cell Adhesion, Richard H. Singiser, Richard O. Mccann

Molecular and Cellular Biochemistry Faculty Publications

BACKGROUND: Talins are large, modular cytoskeletal proteins found in animals and amoebozoans such as Dictyostelium discoideum. Since the identification of a second talin gene in vertebrates, it has become increasingly clear that vertebrate Talin1 and Talin2 have non-redundant roles as essential links between integrins and the actin cytoskeleton in distinct plasma membrane-associated adhesion complexes. The conserved C-terminal I/LWEQ module is important for talin function. This structural element mediates the interaction of talins with F-actin. The I/LWEQ module also targets mammalian Talin1 to focal adhesion complexes, which are dynamic multicomponent assemblies required for cell adhesion and cell motility. Although Talin1 is …

Landscape Change In The South Prong Alafia River Basin, Kimberly Sarah Koenig

USF Tampa Graduate Theses and Dissertations

West-central Florida has supplied much of the national and global demand for phosphate for over 100 years. The two main tributaries of the Alafia River, the North and South Prongs, have been extensively modified by the strip mining, benefaction, and chemical processing activities associated with the phosphate mining industry. Using aerial photos, an analysis of landscape change in the South Prong Alafia River drainage basin (357.4 km2) between 1940, 1970, and 2004 was conducted. A modified Florida Land Use, Land Cover, and Forms Classification System code (FLUCCS) was used to classify and measure change through the study period. Change in …

Traveling Salesman Problem: A Foveating Pyramid Model, Zygmunt Pizlo, Emil Stefanov, John Saalweachter, Zheng Li, Yll Haxhimusa, Walter G. Kropatsch

The Journal of Problem Solving

We tested human performance on the Euclidean Traveling Salesman Problem using problems with 6–50 cities. Results confirmed our earlier findings that: (a) the time of solving a problem is proportional to the number of cities, and (b) the solution error grows very slowly with the number of cities. We formulated a new version of a pyramid model. The new model has an adaptive spatial structure, and it simulates visual acuity and visual attention. Specifically, the model solves the E-TSP problem sequentially by moving attention from city to city, the same way human subjects do. The model includes a parameter representing …

Visual Learning Objects: Enable Faculty To Focus On Active Learning, Pandeli Glavanis Dr.

Faculty Journal Articles

In two recent issues of New Chalk Talk (Vol.6, Issue 2 & 6) I suggested that “learning objects” enhance active learning and that “visual learning objects”, in particular, contribute significantly to the learning relationship. In this issue I wish to elaborate on how such “visual learning objects” are the key element that liberates faculty from having to design and construct their own demonstrations and illustrations (reinvent the wheel) in their respective courses and thus enable them to focus on critical and active learning instead.

Effects Of Visual Distractions In The Classroom Environment On The Time On Task Of Elementary Students With Adhd, Kate E. S. Harris

Theses & Honors Papers

The focus of this study is to demonstrate that the visual distractions, narrowly defined as wall decoration, in an elementary classroom can be a factor in the amount of time students with ADHD spend on-task in that classroom. This study builds upon the information revealed by studies conducted by such researchers as Creekmore (1987), Cruickshank (1967), Doyle, Anderson, and Halcomb (1976), and Steinkamp (1980), which tested the effects of visual distractions on participants with ADD/HD . These studies did not use learning tasks and used distractions that are not typical to an elementary classroom. This study attempted to answer the …
