Tertiary Alphabet For The Observable Protein Structural Universe, Craig\ O. Mackenzie, Jianfu Zhou, Gevorg Grigoryan

Dartmouth Scholarship

Here, we systematically decompose the known protein structural universe into its basic elements, which we dub tertiary structural motifs (TERMs). A TERM is a compact backbone fragment that captures the secondary, tertiary, and quaternary environments around a given residue, comprising one or more disjoint segments (three on average). We seek the set of universal TERMs that capture all structure in the Protein Data Bank (PDB), finding remarkable degeneracy. Only ∼600 TERMs are sufficient to describe 50% of the PDB at sub-Angstrom resolution. However, more rare geometries also exist, and the overall structural coverage grows logarithmically with the number of TERMs. …

Salivary Microbiomes Of Indigenous Tsimane Mothers And Infants Are Distinct Despite Frequent Premastication, Cliff S. Han, Melanie Ann Martin, Armand E.K. Dichosa, Ashlynn R. Daughton, Seth Frietze, Hillard Kaplan, Michael D. Gurven, Joe Alcock

ESI Publications

Background. Premastication, the transfer of pre-chewed food, is a common infant and young child feeding practice among the Tsimane, forager-horticulturalists living in the Bolivian Amazon. Research conducted primarily with Western populations has shown that infants harbor distinct oral microbiota from their mothers. Premastication, which is less common in these populations, may influence the colonization and maturation of infant oral microbiota, including via transmission of oral pathogens. We collected premasticated food and saliva samples from Tsimane mothers and infants (9-24 months of age) to test for evidence of bacterial transmission in premasticated foods and overlap in maternal and infant salivary …

Less Citation, Less Dissemination: The Case Of French Psychoanalysis, Rémy Potier, Olivier Putois, Charlotte Dolez, Elliot Jurist

Publications and Research

The future of all publishing is open to question, and this is especially true in the case of psychoanalytic publishing. Stepansky (2009) has explored the future of psychoanalytic publishing with a particular emphasis upon how the digital era has had an impact upon the decline of scholarly publication in the United States. If this trend continues, the survival of contemporary psychoanalytic research will depend upon its capacity to embrace and utilize digital publishing.

Echoing this perspective, we tried to determine whether the seemingly small international visibility of contemporary French psychoanalytic research could be related to its lack of acknowledgment of …

Pepper Mild Mottle Virus As A Surrogate For Enteric Viruses: Implications For Assessing Water Quality, Erin Michelle Symonds

USF Tampa Graduate Theses and Dissertations

Less than 10% of the world’s domestic wastewater is disinfected prior to discharge into surface waters; therefore, human exposure to diverse wastewater-related pathogens results in millions of cases of illness each year. Among the enteric pathogens, viruses represent an important group of emerging pathogens and are frequently the cause of food- and water-borne outbreaks of illness. Although the World Health Organization and many government agencies mandate the use of bacterial indicators to identify poor microbial water quality, it is well known that these indicators poorly correlate with fecal pollution contamination events and risk of disease. The field of public health-related …

Formation Of Trihalomethanes (Thms) As Disinfection By-Products (Dbps) When Treated Municipal Wastewater Is Disinfected With Sodium Hypochlorite, Helene Kassouf

USF Tampa Graduate Theses and Dissertations

Disinfection is an essential process in the treatment of municipal wastewater before the treated wastewater can be discharged to the environment. Hillsborough County's Northwest Regional Water Reclamation Facility (NWRWRF) in Tampa, Florida, currently uses ultraviolet (UV) light for disinfection. However, this method has proven expensive to implement and maintain, and may not be effective if the light transmission is poor. For these reasons, Hillsborough County is considering switching from UV light to sodium hypochlorite for disinfection. However, hypochlorite (chlorine) disinfection has disadvantages as well, such as the production of disinfection by-products (DBPs) such as trihalomethanes (THM) and haloacetic acids (HAAs), …

A Habitat Analysis Of Estuarine Fishes And Invertebrates, With Observations On The Effects Of Habitat-Factor Resolution, Brianna Michaud

USF Tampa Graduate Theses and Dissertations

Between 1988 and 2014, otter trawls, seine nets, and plankton nets were deployed along the salinity gradients of 18 estuaries by the University of South Florida and the Florida Fish and Wildlife Research Institute (FWRI, a research branch of the Florida Fish and Wildlife Conservation Commission). The purpose of these surveys was to document the responses of aquatic estuarine biota to variation in the quantity and quality of freshwater inflows that were being managed by the Southwest Florida Water Management District (SWFWMD).

In the present analyses, four community types collected by these gears were compared with a diversity of habitat …

Comparing Game Simulation To Concept Models For Student-Centered Learning In Biology, Margaurete Romero

USF Tampa Graduate Theses and Dissertations

Science education research continues to demonstrate improved learning with active-learning techniques compared to lectures. However, the question of which active-learning methods are the most effective for learning complex scientific principles in various context still remains. Models are commonly used in activities that allow students to simplify complex systems and understand how components interact. I investigated the outcomes for student learning and engagement of two model-based activities - concept models and game simulations. The activities were conducted in an introductory biology course in sixteen discussion sections. Eight sections were assigned to the concept model activity and eight to the simulation activity. …

Corrosion Characteristics Of Magnesium Under Varying Surface Roughness Conditions, Yahya Efe Yayoglu

USF Tampa Graduate Theses and Dissertations

The biggest challenge with magnesium alloy biodegradable implants is the rapid corrosion at the earlier stages of the healing process after implantation. In this research, the impact of surface roughness generated by different means on the corrosion rate of AZ31 magnesium alloy in a simulated biologic environment is investigated. In order to perform accurate experimentation, an in vitro setup is assembled that simulates the human body environment accurately has been prepared using Schinhammer’s in vitro immersion testing setup and Kokubo’s Simulated Body Fluid (SBF). For the immersion test of Mg in SBF, several surface texture groups of Mg have been …

The Self-Directed Learning Actions Of Women Regarding The Menopause Transition, Jamie Johnson Cooper

USF Tampa Graduate Theses and Dissertations

Research indicates that increased knowledge about the menopause transition positively impacts a woman’s attitude about this stage in her life, and a more positive attitude leads to less distress during the transition. However, there has been no research regarding how women gain this knowledge about menopause, what factors in her environment may hinder or assist her, or how women’s knowledge of menopause is leveraged by health care providers to help facilitate her menopause transition.

The purpose of this research was to explore the self-directed learning actions of women regarding their search for information about menopause, and to understand what factors, …

Resource Use Overlap In A Native Grouper And Invasive Lionfish, Joseph Schmidt Curtis

USF Tampa Graduate Theses and Dissertations

Invasive species can severely disrupt biological communities through their interactions with native organisms, yet little is known about the response of marine predators to the establishment of a competitive invasive fish. In the western Atlantic, invasive Indo-Pacific lionfishes (Pterois spp.) may represent a novel competitor to several commercially and ecologically important native species. However, there is a scarcity of empirical research documenting comparative resource use of cohabitant lionfish and native fishes, as well the physiological consequences that may result from interspecific interactions with the invasive species. For this thesis, I conducted two studies designed to elucidate the strength …

How Many Babies With Hearing Loss Will Be Missed By Repeated Newborn Hearing Screening With Otoacoustic Emissions Due To Statistical Artifact?, Karl R. White, Lauri H. Nelson, Karen F. Munoz

Journal of Early Hearing Detection and Intervention

Objective: People who manage newborn hearing screening programs are often told that repeating OAE hearing screening more than two or three times per ear unacceptably increases the probability of false-negatives (i.e., passing babies who have permanent hearing loss). This study evaluated the accuracy of that recommendation.

Design: A 2.0 cc coupler and three human ears with hearing loss were used to estimate the number of false-negative results per 1,000 OAE screening tests. Using those results, together with the prevalence of hearing loss among newborns, we calculated the number of babies that would be missed due to repeated testing.

Results: If …

Tabloid Sensationalism Or Revolutionary Feminism? The First-Wave Feminist Movement In An Irish Women’S Periodical, Sonja Tiernan

Irish Communication Review

By 1928 women had achieved many of the objectives of the first-wave of the feminist movement. They had secured political franchise in general elections, girls benefitted from improved access to education and working women were gradually experiencing better conditions in the workplace. However, Europe remained under the rule of a patriarchy and newspapers were controlled by men within that system.

Feature Writing In Women's Magazines: A Limited Ideological Challenge, Susan Liddy

Irish Communication Review

Since the emergence of the International women's movement in the early 1970s. women's magazines have increasingly popularized feminist Ideas. The fragmented format of the genre ensures that a debate on feminist issues can surface in features side by side such old reliables as beauty tips, recipes or advice on how to attract and keep a man. In 1991, over one third of feature writing in Woman's Way and three quarters in U, reflected items from the Irish feminist agenda. Issues like the wage gap, the absence of state funded childcare, the need for equal status legislation , rape and domestic …

Designing Fixed-Base Operations Utilizing Systems Engineering Principles, Ross L. Stephenson Jr., David A. Carroll

Journal of Aviation Technology and Engineering

There are currently over 3,200 fixed-base operations (FBOs) conducting business in the United States attempting to meet the demands of FAA Part 91, Part 135, and a limited number of Part 121 operations. With the US economy slowly climbing out of the trough during 2013, the utilization of fixed-base operations has become more attractive and economical to the corporate business and the affluent recreational traveler. Despite the increased flight activities utilizing the services of fixed-base operators, keen competition, rising fuel cost, and the economies of scale recognized by large FBO franchises significantly erode the profitability and sustainability of smaller FBOs. …

A Mouse Model For Binge-Level Methamphetamine Use, Shkelzen Shabani, Sydney K. Houlton, Laura Hellmuth, Erika Mojica, John R K Mootz, Zhen Zhu, Cheryl Reed, Tamara J. Phillips

Peer Reviewed Articles

Binge/crash cycles of methamphetamine (MA) use are frequently reported by individuals suffering from MA use disorders. A MA binge is self-reported as multiple daily doses that commonly accumulate to 800 mg/day (~10 mg/kg/day for a 170 pound human). A genetic animal model with a similar vulnerability to binge-level MA intake is missing. We used selectively bred MA high drinking (MAHDR) and low drinking (MALDR) mouse lines to determine whether several procedural variations would result in binge-level MA intake. Data were also collected in two progenitor populations of the MA drinking lines, the DBA/2J (D2) strain and the F2 cross of …

Overlap In The Seasonal Infection Patterns Of Avian Malaria Parasites And West Nile Virus In Vectors And Hosts, Matthew Medeiros, Robert Ricklefs, Jeffrey Brawn, Marilyn Ruiz, Tony Goldberg, Gabriel Hamer

Biology Department Faculty Works

Multiple vector-borne pathogens often circulate in the same vector and host communities, and seasonal infection dynamics influence the potential for pathogen interactions. Here, we explore the seasonal infection patterns of avian malaria (Haemosporida) parasites (Plasmodium and Haemoproteus) and West Nile virus (WNV) in birds and mosquitoes in suburban Chicago. We show that both pathogens vary seasonally in Culex mosquitoes and avian hosts, but that patterns of covariation are complex. Different putative Plasmodium species varied asynchronously across the season in mosquitoes and birds, suggesting that different forces may govern their transmission. Infections of Culex mosquitoes with Plasmodium parasites were positively associated …

The Pop-Up Effect: Why Buoyant Spheres Don’T Always Leap Out Of The Water | College Of Engineering, Usu College Of Engineering

College of Engineering News

News Release – LOGAN, UTAH, Nov. 2, 2016 – It’s a common swimming pool game: Force a buoyant ball underwater and let it go. The ball springs to the surface and jumps into the air. But, submerge the ball deeper underwater and the effect is often disappointing. Contrary to intuition, increasing the release depth often leads to a decreased pop-up height.
