Pasteurization Of Milk, Alejandro Barbosa Alzate

Undergraduate Journal of Mathematical Modeling: One + Two

We determined the time it takes milk, which is heated from 60°F to 150°F, to achieve pasteurization and compared this result with the standard pasteurization process of heating milk at a constant temperature of 150°F for 30 minutes. Instead of directly quantifying the bacterium population, we considered the bacteria to milk concentration ratio. To solve for the unknown time, we equated the final bacterium concentration ratio achieved through both varied temperature and constant temperature. After equating the final pasteurization concentrations we were unable to find an analytical solution, so we used numerical techniques to find the unknown heating time.

Light Attenuation At Molasses Reef, Ashley Earls

Undergraduate Journal of Mathematical Modeling: One + Two

Estimating the amount of light available at different depths of the ocean is important for gaining a better understanding of coral reefs. It is especially useful to be able to get such estimates without having to perform direct measurements. Although accurate, the direct measurements are costly, time consuming, and usually limited to relatively small areas of interest.

One statistic that could be useful for estimating the amount of available light is the rate at which it declines with depth (the rate of light attenuation). In this project, this rate is calculated for four different wavelengths using data for 30m water …

The Evolution Of The Family, Benjamin E. Hardisty

USF St. Petersburg campus Master's Theses (Graduate)

Biological levels of complexity usually begin with the cell and extend forward to tissues, organs, organ systems, organisms, populations, community, and end with ecosystems. The family is a unit of biological complexity is missing. As a result, the evolution of altruism and cooperation from a natural selection perspective has not been produced. In the following chapters, I argue that the family is a unit of biological complexity will illuminate such mysteries as the evolution of eusociality, theories of lifetime fitness—sometimes referred to as Lifetime Reproductive Success (LRS)— cultural learning and its importance as a parallel mechanism of inheritance, finally, the …

Diet Analysis And Community Characteristics Of Lepomis (Sunfish) Species Congregating Near Natural Spring Vents Of The Rainbow River, Florida, Michael S. Sears

USF St. Petersburg campus Master's Theses (Graduate)

Little is known about the ecology of natural springs and the influence spring vents have on fish populations. This study explores fish population characteristics, such as abundance, diversity, and length distributions near headwater spring vents and downstream away from the spring vents within the Rainbow River, located in central Florida. The population characteristics examined are useful to resource managers when evaluating the possible impacts on fish populations from increased groundwater withdrawals and subsequent lower discharge rates into large spring-fed rivers. Initial field observations led to the hypothesis that Lepomis species feed on organisms expelled from the spring vents. Electrofishing and …

Stakeholder Perceptions Of The Gulf Of Mexico Grouper And Tilefish Individual Fishing Quota Program, Britni N. Tokotch

USF St. Petersburg campus Master's Theses (Graduate)

Individual Fishing Quota Programs (IFQs) are a fishery management method in which percentages of a fishery are allocated to individual fishers, thus specifying how much of that species each fisher can harvest. The purpose of this study is to determine the opinions of stakeholders to the recently implemented Gulf of Mexico grouper and tilefish IFQ program. Many studies have been conducted on the biological implications of IFQ programs but few have focused on social perceptions. Data was obtained through mail-in surveys and analysis consisted of two-sample two-tailed t-test and two-sample proportion testing. Results show that a stakeholder’s perspective on the …

Restoration Of Propeller Scars In Seagrass Meadows Using Sediment Tubes And Design Of A Working Prototype Unmanned Surface Vehicle For Seagrass Studies, Karen Leigh Dreger

USF St. Petersburg campus Master's Theses (Graduate)

Sediment tubes were placed in the unvegetated trenches created in seagrass meadows by boat propellers. The sediment tubes facilitated the natural recovery by stabilizing the sediments and by allowing recruitment of healthy seagrass from the surrounding, undisturbed area. Still images taken of the study sites before and after restoration were assigned a Braun-Blanquet ranking based on the percentage coverage of seagrass. Statistical analysis, using the Mann-Whitney U Test, supported the visual observation that the sediment tubes successfully facilitated natural restoration of the propeller scars. After two years there was an increase in the percent coverage of seagrass at each of …

Patterns Of Indigenous Resilience In The Amazon: A Case Study Of Huaorani Hunting In Ecuador, Flora Lu

Journal of Ecological Anthropology

This paper takes a resilience approach to examining human forager-prey dynamics using as a case study Huaorani hunting in the Ecuadorian Amazon. I compare methodologically similar datasets collected in the same Huaorani villages in 1996-1997 and 2001. Rather than assuming that human hunters simply act on prey species and linearly drive them to depletion, a resilience approach views this dynamic as a complex social and ecological system characterized by feedbacks, nonlinearities, uncertainty, unpredictability, and non-equilibrium dynamics. Using a computer simulation of human foragers and prey (published previously), I highlight how even using relatively simple assumptions, the human forager-prey relationship exhibits …

Tribal-Federal Collaboration In Resource Management, Ellen M. Donoghue, Sara A. Thompson, John C. Bliss

Journal of Ecological Anthropology

The increase in collaborative projects involving American Indian tribes and natural resource management agencies in the United States reflects two emergent trends: 1) the use of collaborative approaches between agencies and groups in managing natural resources; and 2) the concurrent increased recognition of American Indian rights, institutionalization of consultation processes, and a general movement of Indian self-determination. This article focuses on institutional mechanisms that bring together tribes and natural resource management agencies in collaborative processes to achieve mutually desired resource management objectives. Using qualitative analysis of data from ten collaborative projects across the United States, we identify attributes of collaborative …

Communally Discerning A Covenant Of Hospitality For The Care Of Children At Westview Boys' Home, Ron Bruner

Doctor of Ministry Theses and Dissertations

This project addressed the lack of a covenant defining the practice of hospitality towards children for team members of Westview Boys’ Home. The purpose of the project was to facilitate the creation of such a covenant. The Westview ministry team already claimed hospitality as a strength; the hope was that reframing the ministry around this strength would improve the quality of care for children and the quality of life for the community. Invited into a communal discernment process (the methodology), the ministry team invested weeks in the examination of biblical texts, theological tradition, personal and communal narratives, cultural trends, psychological …

Defining Fear And Aggression: Typological Emotive Responses To Perceptions Of Textual Symbols, Donna Lynn Salazar

Criminology & Criminal Justice Theses - Archive

Millennial technology has shed new light on early biological theories of crime. Recent evidence supports a new paradigm in criminological research designed to embrace an integration of neuro-scientific, psychological, and sociological theories in order to understand the multi-dimensional characteristics of causality involved in criminal behavior. The current study explores the value of an integrated approach to define typological fear and aggression emotive responses utilizing symbolic interaction as the mechanism by which the various disciplines interact. Through perceptions of emotionally charged textual symbols, typological representations of fear and aggression, and a 3-Part electronic survey instrument, the study reveals support for an …

Mathematical Modeling For Phagocyte Transmigration And Reverse Engineering, Min Gon Kang

Computer Science and Engineering Theses - Archive

Computational modeling and simulation have been used as an important tool to analyze the behavior of a complex biology system. Typically, the biology system is a complex non-linear system where a large number of components are involved. One of the major obstacles in computational modeling and simulation is to determine a large number of parameters in the mathematical equations representing biological properties of the system.To tackle this problem, we have developed a global optimization method, called Discrete Selection Levenberg-Marquardt (DSLM), for parameter estimation. The method uses a non-linear least square approach to approximate the solution of over-determined systems. For fast …

Real Time Hardware And Software Systems For Micro Air Vehicle Flight Control Testing, Christopher Dale Mcmurrough

Computer Science and Engineering Theses - Archive

The trend of increasing capabilities of micro scale electrical, mechanical, and computing systems is opening up the possibilities of new unmanned vehicle platforms. Both unmanned aerial and ground vehicles have traditionally been created from large conventional platforms such as automobiles, rotorcraft, and fixed wing aircraft. These conventional chassis designs are durable and proven, but the benefits of automating these types of platforms are limited by their inherent human-centric design. Many real-world applications would benefit greatly from vehicle classes designed with unconventional means such as biologically inspired locomotion. Micro air vehicles are a class of vehicles that have recently began moving …

The Jacksboro Limestone is a member of the Graham Formation of the Virgilian (Upper Pennsylvanian) and is exposed only in and around the city of Jacksboro in central Jack County, Texas. The purposes of this investigation were to study the vertical and lateral microfacies changes that occur throughout the Jacksboro Limestone in its outcrop belt and to discuss its relationship as the basal regressive cycle in the Virgilian part of the Pennsylvanian, in particular: (1) describe and classify the primary limestone lithofacies on the basis of carbonate rock textures, (2) interpret, if possible, the depositional environment and physical energy of …

Using Shewanella Baltica Ecotypes As A Model For Transcriptional Variation At The Population Level, William Sealy Hambright

Biology Theses - Archive

Eukaryotic studies have shown considerable transcriptional variation among individuals of the same population. Owing to the cost of sequencing entire eukaryotic genomes, tested organisms were assumed to be genomically similar or even identical. We overcame this necessary assumption by using four sequenced strains of the bacterium Shewanella baltica, (OS155, OS185, OS195, OS223), as models to assess transcriptional variation and ecotype formation within a prokaryotic population. The strains were isolated from various depths throughout a water column of the Baltic Sea occupying different ecological niches characterized by various abiotic parameters. Although their genome sequences are strikingly similar, when grown in the …

A Tale Of Three Phytopathogens: Impact Of Transposable Elements On Genome Evolution, Komal Vadnagara

Biology Theses - Archive

The genus Phytophthora harbors some notorious plant pathogens like Phytophthora infestans (causal of Irish potato famine), Phytophthora sojae (soybean rot agent), and Phytophthora ramorum (responsible for sudden oak death) that have significant economic, ecological and environmental impact. These phytopathogens exhibit remarkable phenotypic instability and vary tremendously in genome size from 65 Mb (P. ramorum) to 240 Mb (P. infestans). Complete draft genome sequences revealed that a substantial portion of their genome is occupied by highly repetitive DNA. This extreme genome plasticity is due to an infestation of repetitive virus-like genomic parasites called transposable elements (TEs). TEs are sometimes called jumping …

Environmental Regulation Of Stomate-Based Defense Against Bacterial Infection In Arabidopsis, Reejana Chitrakar

Biology Theses - Archive

Stomata are natural openings in the plant epidermis responsible for gas (O2 and CO2) exchange between plant interior and environment. They are formed by a pair of guard cells, which are able to close the stomatal pore in response to a number of external factors including light intensity, carbon dioxide concentration, and relative humidity. The stomatal pore is also the main route for pathogen entry into leaves, a crucial step for disease development. Recent studies have unveiled that closure of the pore is effective in preventing bacterial disease in Arabidopsis plants and the successful plant pathogen Pseudomonas syringae pv. tomato …

Comparing The Genome Expression Profiles Of Verrucomicrobium Sp. Strain Tav2 Cells Grown Under Two Different Oxygen Concentrations, Austin Willis

Biology Theses - Archive

Termites are significantly different in their lifestyles and organization but most are linked by the common trait in degrading plant material, whether it is leaf litter, wood, soil or animal waste. They consume the cellulose, hemicelluloses and lignin that make up the plant material but rely on a food web consisting of about 270 different phylotypes of microorganisms to break down the biomass into usable nutrients. Isolated from the hindgut of the termite Reticulitermis flavipes, one such organism is Verrucomicrobium sp. strain TAV2. Members of this relatively new bacterium phylum have rigid peptidoglycan with some possessing prosthecae. They have been …

Characterization Of Anti-Rotavirus Activities Of Saponin Extracts From Quillaja Saponaria, Ka Ian Tam

Biology Dissertations - Archive

Rotavirus is the leading cause of severe diarrhea disease in newborns and young children worldwide, estimated to be responsible for over 500,000 adolescent deaths mostly in developing countries each year. Rotavirus-related deaths represent approximately 5% of all deaths in children younger than five years of age worldwide. Previous research has shown that Quillaja saponins demonstrate strong antiviral activity against 7 different viruses, including rotavirus, in vitro. Quillaja saponins, a natural, aqueous extract of triterpenoid saponins obtained from Quillaja saponaria, the Chilean Soap Bark tree that display strong adjuvant activity when used in vaccines. In this study, Quillaja saponins are stable …

Integration Mechanism Of The Site Specific Non-Ltr Retrotransposon, R2bm, Christi Lynn Hull

Biology Theses - Archive

The focus of this thesis is the mechanistic study of non-LTR retrotransposon replication using the site specific transposon R2Bm. Non-LTR retrotransposons integrate into new chromosomal sites by copying their RNA back into DNA at the site of insertion using an exposed chromosomal 3' OH to prime cDNA synthesis.1 Although some of the early steps of an integration event have been detailed, how the element completes integration remains unknown.¹ ² ³ ⁴ ⁵ ⁶ Clarifying the last integration step, known as second strand synthesis, is a major goal of this research. In order to accomplish this, R2 RNA and protein substrates …
