Validating The Accuracy Of Neatwork, A Rural Gravity Fed Water Distribution System Design Program, Using Field Data In The Comarca Ngöbe-Bugle, Panama, Maria Briones

USF Tampa Graduate Theses and Dissertations

Despite the sustainable development goals to increase access to improved water there are still 884 million people in the world without access to an improved water source (WHO, 2017). One method to improve access to water in rural, mountainous areas, is through construction of gravity fed water distribution systems. These systems should be designed based upon fundamental principles of hydraulics. One method of doing so in a time efficient manner with minimal engineering knowledge is to utilize a downloadable computer program such as Neatwork, which aids in design of rural, gravity fed water distribution systems and has been used by …

Studying Egfr Signaling Through Single Molecule Imaging And Computational Modeling, Emanuel Salazar Cavazos

Biomedical Sciences ETDs

Signaling through the Epidermal Growth Factor Receptor (EGFR) plays an important role in both physiological and cancer-related processes. In this work, single-molecule microscopy measurements and computational modeling were closely integrated to better understand the mechanisms that regulate EGFR signaling. Technical improvements were made over the previously described Single-Molecule Pull-down (SiMPull) assay to facilitate direct detection of the phosphorylation state of thousands of individual receptors, and thereby estimate both the fraction of receptors phosphorylated at specific tyrosine residues and the frequency of multisite phosphorylation. These improvements enabled the first direct detection of multisite phosphorylation on full-length Epidermal Growth Factor Receptor (EGFR), …

Sources And Fates Of Carbamyl Phosphate: A Labile Energy-Rich Molecule With Multiple Facets., Dashuang Shi, Ljubica Caldovic, Mendel Tuchman

Genomics and Precision Medicine Faculty Publications

Carbamyl phosphate (CP) is well-known as an essential intermediate of pyrimidine and arginine/urea biosynthesis. Chemically, CP can be easily synthesized from dihydrogen phosphate and cyanate. Enzymatically, CP can be synthesized using three different classes of enzymes: (1) ATP-grasp fold protein based carbamyl phosphate synthetase (CPS); (2) Amino-acid kinase fold carbamate kinase (CK)-like CPS (anabolic CK or aCK); and (3) Catabolic transcarbamylase. The first class of CPS can be further divided into three different types of CPS as CPS I, CPS II, and CPS III depending on the usage of ammonium or glutamine as its nitrogen source, and whether

Multi-Behavioral Endpoint Testing Of An 87-Chemical Compound Library In Freshwater Planarians, S. Zhang, D. Hagstrom, P. Hayes, A. Graham, Eva-Maria S. Collins

Biology Faculty Works

There is an increased recognition in the field of toxicology of the value of medium-to-high-throughput screening methods using in vitro and alternative animal models. We have previously introduced the asexual freshwater planarian Dugesia japonica as a new alternative animal model and proposed that it is particularly well-suited for the study of developmental neurotoxicology. In this paper, we discuss how we have expanded and automated our screening methodology to allow for fast screening of multiple behavioral endpoints, developmental toxicity, and mortality. Using an 87-compound library provided by the National Toxicology Program (NTP), consisting of known and suspected neurotoxicants, including drugs, flame …

Wild Turkey Occupancy In A Prairie Landscape, Joshua C. Courlas, R. Scott Lutz

The Prairie Naturalist

We investigated wild turkey (Meleagris gallopavo) distribution in prairie landscapes in North Dakota using occupancy modeling in two stages. In 2012, we extensively surveyed ecoregions across the state and in 2013, intensively surveyed the ecoregion with the highest probability of occupancy. Occupancy models from the statewide survey indicated wild turkeys were sparse in ecoregions with primarily agricultural landscapes, were found associated with wooded riparian cover, and found most frequently in the Missouri River Plateau ecoregion. In the Missouri River Plateau, our occupancy models identified that an additive model including mean patch area of cropland fields and spatial aggregation of forest …

Spatiotemporal Distribution Of Waterfowl Disease Outbreaks In Kansas, Usa, Thomas A. Becker, Adam A. Ahlers, Shane Hesting, David A. Haukos

The Prairie Naturalist

Causes and impacts of disease outbreaks in wild bird populations are rarely studied beyond documentation of large epizootic events. In Kansas, USA, a central disease surveillance and reporting protocol currently does not exist within the Kansas Department of Wildlife, Parks and Tourism, which has led to a lack of available knowledge of disease occurrences that could be used to predict and manage future outbreaks. We compiled historic records of documented waterbird disease outbreaks in Kansas from 1967–2014 and related the frequency of outbreaks with light geese (Ross’s goose [Anser rossii]; Snow goose [A. caerulescens]) populations from 1970–2014. We found 32 …

Book Reviews: Force Of Nature: George Fell, Founder Of The Natural Areas Movement. Arthur Melville Pearson., James R. Herkert

The Prairie Naturalist

Arthur Melville Pearson’s Force of Nature is a book that tells two very interesting and intertwined stories. One is a story of how perseverance and determination can drive an individual to accomplish great things. And the other is a story of how the modern day natural areas movement came to be. Fortunately for those interested in conservation and natural areas protection, those two stories were combined in the life of George Fell (1916-1994). In Fell’s home state of Illinois, where his impact is widely known, his name is synonymous with conservation. In other places where his impact is less well …

Lekking Behavior Of A Sharp-Tailed Grouse In South-Central Nebraska, Kelsey C. King, Andrew J. Caven, Keith Geluso

The Prairie Naturalist

Sharp-tailed grouse (Tympanuchus phasianellus; STGR) occur throughout much of the northern Great Plains, and historically were suspected to have ranged as far south as Kansas (Connelly et al. 1998). Sharp-tailed grouse were the dominant grouse in Nebraska 200 years ago, but early settlers and their associated agricultural practices extirpated STGR from much of their former range, including Kansas and southern Nebraska (Sisson 1976, Johnsgard 2016). During the period of initial land conversion, the greater prairie-chicken (T. cupido; GRPC) filled the void, benefiting from small plots of cropland providing winter forage, and outcompeting the STGR (Johnsgard and Wood 1968, Svedarsky et …

Age And Growth Of Cottonwood Trees Along The Missouri River, North Dakota, Jonathan M. Friedman, Fisher R. Ankney, J. Marshall Wolf

The Prairie Naturalist

The relict plains cottonwood (Populus deltoides subsp. monilifera) forest along the Missouri River between Lakes Sakakawea and Oahe includes trees as large as two meters in diameter. We cored 24 of these trees to determine their age and suitability for flow reconstruction. Because most of the trees were rotten in the center, we developed a method to estimate the date of the center ring that accounts for the increase in ring width toward the center. Estimated center ring dates were as early as 1806. Cottonwood growth at a dry site was correlated with April–August flow prior to construction of Lake …

Skeletal muscle comprises a family of diverse tissues with highly specialized functions. Many acquired diseases, including HIV and COPD, affect specific muscles while sparing others. Even monogenic muscular dystrophies selectively affect certain muscle groups. These observations suggest that factors intrinsic to muscle tissues influence their resistance to disease. Nevertheless, most studies have not addressed transcriptional diversity among skeletal muscles. Here we use RNAseq to profile mRNA expression in skeletal, smooth, and cardiac muscle tissues from mice and rats. Our data set, MuscleDB, reveals extensive transcriptional diversity, with greater than 50% of transcripts differentially expressed among skeletal muscle tissues. We detect …

Radical Social Ecology As Deep Pragmatism: A Call To The Abolition Of Systemic Dissonance And The Minimization Of Entropic Chaos, Arielle Brender

Student Theses 2015-Present

This paper aims to shed light on the dissonance caused by the superimposition of Dominant Human Systems on Natural Systems. I highlight the synthetic nature of Dominant Human Systems as egoic and linguistic phenomenon manufactured by a mere portion of the human population, which renders them inherently oppressive unto peoples and landscapes whose wisdom were barred from the design process. In pursuing a radical pragmatic approach to mending the simultaneous oppression and destruction of the human being and the earth, I highlight the necessity of minimizing entropic chaos caused by excess energy expenditure, an essential feature of systems that aim …

Studying Planarian Regeneration Aboard The International Space Station Within The Student Space Flight Experimental Program, Vista Ssep Mission 11 Team, D. Hagstrom, C. Bartee, Eva-Maria S. Collins

Biology Faculty Works

The growing possibilities of space travel are quickly moving from science fiction to reality. However, to realize the dream of long-term space travel, we must understand how these conditions affect biological and physiological processes. Planarians are master regenerators, famous for their ability to regenerate from very small parts of the original animal. Understanding how this self-repair works may inspire regenerative therapies in humans. Two studies conducted aboard the International Space Station (ISS) showed that planarian regeneration is possible in microgravity. One study reported no regenerative defects, whereas the other study reported behavioral and microbiome alterations post-space travel and found that …

Modeling And Analyzing An Optogenetic System For Photoactivatable Protein Dissociation, Anvin Thomas, James Schaff

Honors Scholar Theses

Computational modeling of cell-cell interactions can grant clues and can answer questions about an experiment, especially for observations about binding interactions and kinetics. This approach was used to investigate an interaction between a light-oxygen-voltage (LOV) domain and an engineered protein called Zdark (Zdk). The LOV domain is membrane-bound while Zdk is cytosolic. The LOV domain and Zdk bind strongly in dark (K_d 26.2 nM), and weakly upon exposure to blue light (K_d > 4 μM). Total internal reflection fluorescence (TIRF) images are acquired of Zdk, the fluorescent species bound to a mCherry tag, and the loss of fluorescence is …

Self-Organized Structures: Modeling Polistes Dominula Nest Construction With Simple Rules, Matthew Harrison

Electronic Theses and Dissertations

The self-organized nest construction behaviors of European paper wasps (Polistes dominula) show potential for adoption in artificial intelligence and robotic systems where centralized control proves challenging. However, P. dominula nest construction mechanisms are not fully understood. This research investigated how nest structures stimulate P. dominula worker action at different stages of nest construction. A novel stochastic site selection model, weighted by simple rules for cell age, height, and wall count, was implemented in a three-dimensional, step-by-step nest construction simulation. The simulation was built on top of a hexagonal coordinate system to improve precision and performance. Real and idealized …

Skeletal, Cardiac, And Respiratory Muscle Function And Histopathology In The P448lneo- Mouse Model Of Fkrp-Deficient Muscular Dystrophy., Qing Yu, Melissa Morales, Ning Li, Alexander G Fritz, Ren Ruobing, Anthony Blaeser, Ershia Francois, Qi-Long Lu, Kanneboyina Nagaraju, Christopher F Spurney

Genomics and Precision Medicine Faculty Publications

BACKGROUND: Fukutin-related protein (FKRP) mutations are the most common cause of dystroglycanopathies known to cause both limb girdle and congenital muscular dystrophy. The P448Lneo- mouse model has a knock-in mutation in the FKRP gene and develops skeletal, respiratory, and cardiac muscle disease.

METHODS: We studied the natural history of the P448Lneo- mouse model over 9 months and the effects of twice weekly treadmill running. Forelimb and hindlimb grip strength (Columbus Instruments) and overall activity (Omnitech Electronics) assessed skeletal muscle function. Echocardiography was performed using VisualSonics Vevo 770 (FujiFilm VisualSonics). Plethysmography was performed using whole body system (ADInstruments). Histological evaluations included …

Data-Driven Computational Approach To Study Bio-Molecular Interactions, Misagh Naderi

LSU Doctoral Dissertations

Proteins commonly convey their functions in coordination with other proteins, small molecules and/or other biological assemblies such as sugars, lipids, DNA or RNA. Understanding the nature of these interactions is therefore central to improving our knowledge of biological systems. This body of work is a consolidation of three different computational approaches to study bio-molecular interactions: large-scale protein-ligand modeling, fragment-based cheminformatics, and computational analysis of interactions in single proteins.

The first issue that is addressed in this study is the scarcity of atomic crystal structures of protein-drug complexes. In general, a drug molecule’s affinity for multiple protein targets may causes unsolicited …
