Biology-Inspired Approach For Communal Behavior In Massively Deployed Sensor Networks, Kennie H. Jones

Computer Science Theses & Dissertations

Research in wireless sensor networks has accelerated rapidly in recent years. The promise of ubiquitous control of the physical environment opens the way for new applications that will redefine the way we live and work. Due to the small size and low cost of sensor devices, visionaries promise smart systems enabled by deployment of massive numbers of sensors working in concert. To date, most of the research effort has concentrated on forming ad hoc networks under centralized control, which is not scalable to massive deployments. This thesis proposes an alternative approach based on models inspired by biological systems and reports …

Pge2 Receptor Subsets Mediate Hcg Regulation Of The Plasminogen Activator/Plasmin System In Primate Periovulatory Follicles, Nune Markosyan

Theses and Dissertations in Biomedical Sciences

Elevated follicular prostaglandin E2 (PGE2) levels are necessary for follicle rupture during ovulation. As the degradation of the follicle wall requires proteolysis, it was hypothesized that regulation of proteolysis by gonadotropins is PGE2 mediated.

There are four PGE2 receptors: EP1, EP2, EP3 and EP4. To determine which PGE2 receptors are present in monkey periovulatory follicles, granulosa cells and whole ovaries were collected 0, 12, 24, and 36 hours after administration of an ovulatory dose of human chorionic gonadotropin (hCG), or 36 hours after hCG from monkeys that received the prostaglandin (PG) synthesis inhibitor celecoxib. All EP receptor mRNAs were present …

Gender Observations And Study Abroad: How Students Reconcile Cross-Cultural Differences Related To Gender, Jody E. Jessup-Anger

College of Education Faculty Research and Publications

The purpose of the current study was to gain a better understanding of how gender was observed by a group of students participating in a 3-week study abroad program entitled, Food, Environment and Social Systems, which took place in Australia and New Zealand in May 2006. I examined the messages students received about gender in Australia and New Zealand, whether the students were cognizant of these messages, and how they made meaning of the messages in light of their own gender identity.

Weak Competition Among Tropical Tree Seedlings: Implications For Species Coexistence, C.E. Timothy Paine, Kyle E. Harms, Stefan A. Schnitzer, Walter P. Carson

Biological Sciences Faculty Research and Publications

The intensity of competition among forest tree seedlings is poorly understood, but has important ramifications for their recruitment and for the maintenance of species diversity. Intense competition among seedlings could allow competitively dominant species to exclude subordinate species. Alternatively, the low density and small stature of forest tree seedlings could preclude intense interseedling competition. In this case, other processes, such as size‐asymmetric competition with adults, interactions with consumers, or neutral dynamics would prevail as those structuring the forest understory. We tested the intensity of, and potential for, intraspecific competition among tree seedlings of three species (Brosimum alicastrum, Matisia …

Bisphenol A Blood And Saliva Levels Prior To And After Dental Sealant Placement In Adults, Joyce Marie Downs

Dental Hygiene Theses & Dissertations

Placement of pit and fissure dental sealants is an effective therapy for tooth decay prevention and is widely accepted as a standard of care throughout the United States. Pit and fissure dental sealants (sealants) are manufactured using the resin component of composite dental materials, formed by reacting glycidyl methacrylate with bisphenol A. Bisphenol A (BPA) is a hormonally active, synthetic chemical that is part of a broad group of chemicals known as endocrine disrupting compounds, xenoestrogens, which mimic bioactivity of estrogen. This study measured BP A in saliva and blood after the placement of a widely used, pit and fissure …

Microtextures Of Cyanobacterial Mats In Siliciclastic Sedimentary Environments (Modern & Ancient): Applications To The Search For Life On Mars, Dina M. Bower

OES Theses and Dissertations

The current Mars Exploration Rover Program (MER) is one of NASA's most successful missions. The aim of the MER is to explore for possible life on the surface of Mars. My thesis developed new methods of how to detect and to identify microbial mats in siliciclastic sediments (modern and ancient), and to make recommendations on the applicability of MISS as biosignatures. Predominantly, I employed instrumentation portable by future rovers. To search for life on other planets, we need to have information on how this life might look. Most astrobiological studies therefore focus on Earthly analogues of life and its habitats. …

A Phylogeny Of The Snappers (Lutjanidae; Percoidei) Inferred From Cytochrome B Sequence Data, Matthew R. Semcheski

Biological Sciences Theses & Dissertations

The Lutjanidae are economically and ecologically important fishes commonly known as snappers. A morphological study of Lutjanidae concluded that it contained four subfamilies and that together with the family Caesionidae, form the superfamily Lutjanoidea. Although this view was supported elsewhere in the literature, it was later contradicted, treating the caesionids as members of the Lutjanidae. In order to infer a phylogeny of genera within Lutjanidae, the complete cytochrome b gene (1140bp) of 21 lutjanid taxa was sequenced and analyzed along with 19 lutjanid, caesionid, and outgroup sequences obtained from GenBank. Data were analyzed for base composition stationarity and saturation. Phylogenetic …

A Review Of Fibroblast Populated Collagen Lattices, J. C. Dallon, Paul H. Ehrlich

Faculty Publications

Bellaes introduction of the fibroblast populated collagen lattice (FPCL) (1) has facilitated the study of collagen-cell interactions. As a result of the numerous modifications of the casting of FPCL's, the in vivo applications of these in vitro findings has been confusing. Here experimental FPCL contraction findings are viewed in regard to three proposed mechanisms responsible for lattice contraction. The cellular mechanisms responsible for generating FPCL contraction are: cell contraction, cell tractional forces related to cell locomotion, and initial cell elongation and spreading.

Effect Of Matriarchs On Group Interactions, Kinship Fitness, And Differences In Chemosensory Behavior Of African Elephants (Loxodonta Africana), Rhea Marie Esposito

College of Graduate Studies: Theses & Dissertations

Female African elephants exhibit multiple levels of social organization with the family as the functional social unit. Families consist of related females and the oldest female is the matriarch. Related family groups that frequently fuse are termed kinship groups, led by the grand matriarch. I examined matriarch communication behavior across social context and their role in interactions between families at waterholes in Addo Elephant National Park, South Africa. I analyzed three hypotheses for matriarchal effects on group fitness: a) older matriarchs provide greater access to resources, b) older matriarchs lead more social groups, or c) there is no behavior-fitness relationship …

Electron Crystallography Of Aquaporins, Simeon Andrews, Steve Reichow, Tamir Gonen

Chemistry Faculty Publications and Presentations

Aquaporins are a family of ubiquitous membrane proteins that form a pore for the permeation of water. Both electron and X-ray crystallography played major roles in determining the atomic structures of a number of aquaporins. This review focuses on electron crystallography, and its contribution to the field of aquaporin biology. We briefly discuss electron crystallography and the two-dimensional crystallization process. We describe features of aquaporins common to both electron and X-ray crystallographic structures; as well as some structural insights unique to electron crystallography, including aquaporin junction formation and lipid-protein interactions.

Compost Production And Use In Horticulture, Bob Paulin, Peter O'Malley

Bulletins 4000 -

Maintaining and improving soil organic carbon levels is becoming an increasingly important aspect of modern farming. Compost provides potentially one of the most effective ways of applying organic matter to soils and improving organic carbon levels.

Improving soil organic carbon is directly related to soil quality and performance. Increased quality reflects improved biological function (soil health), fertility and physical attributes that include better drainage, reduced compaction and erosion, and improved moisture-holding capability, at least for lighter soils.

Compost is not the only option available. Others include the use of cover or break crops, reducing the use of cultivations, selecting safe …

Effects Of 5 Different Finger Rest Positions On Arm Muscle Activity During Scaling By Dental Hygiene Students, Mary E. Cosaboom-Fitzsimons, Susan Lynn Tolle, Michele L. Darby, Martha L. Walker

Optimizing Product Line Designs: Efficient Methods And Comparisons, Alexandre Belloni, Robert Freund, Matthew Selove, Duncan Simester

Business Faculty Articles and Research

We take advantage of recent advances in optimization methods and computer hardware to identify globally optimal solutions of product line design problems that are too large for complete enumeration. We then use this guarantee of global optimality to benchmark the performance of more practical heuristic methods. We use two sources of data: (1) a conjoint study previously conducted for a real product line design problem, and (2) simulated problems of various sizes. For both data sources, several of the heuristic methods consistently find optimal or near-optimal solutions, including simulated annealing, divide-and-conquer, product-swapping, and genetic algorithms.

Functional Analysis Of A Predicted Flavonol Synthase Gene Family In Arabidopsis, Daniel Owens, Anne B. Alerding, Kevin C. Crosby, Aloka B. Bandara, James H. Westwood, Brenda S.J. Winkel

ETSU Faculty Works

The genome of Arabidopsis (Arabidopsis thaliana) contains five sequences with high similarity to FLAVONOL SYNTHASE1 (AtFLS1), a previously characterized flavonol synthase gene that plays a central role in flavonoid metabolism. This apparent redundancy suggests the possibility that Arabidopsis uses multiple isoforms of FLS with different substrate specificities to mediate the production of the flavonols, quercetin and kaempferol, in a tissue-specific and inducible manner. However, biochemical and genetic analysis of the six AtFLS sequences indicates that, although several of the members are expressed, only AtFLS1 encodes a catalytically competent protein. AtFLS1 also appears to be the only member of this group …

Proteomics Analysis Identifies Molecular Targets Related To Diabetes Mellitus-Associated Bladder Dysfunction, Elizabeth Yohannes, Jinsook Chang, Mark R. Chance

Faculty Scholarship

Protein expression profiles in rat bladder smooth muscle were compared between animal models of streptozotocin-induced diabetes mellitus (STZ-DM) and age-matched controls at 1 week and 2 months after induction of hyper-glycemia with STZ treatment. At each time point, protein samples from four STZ-DM and four age-matched control rat bladder tissues were prepared independently and analyzed together across multiple DIGE gels using a pooled internal standard sample to quantify expression changes with statistical confidence. A total of 100 spots were determined to be significantly changing among the four experimental groups. A subsequent mass spectrometry analysis of the 100 spots identified a …

Killing Of Human Melanoma Cells Induced By Activation Of Class I Interferon-Regulated Signaling Pathways Via Mda-7/Il-24, Suhendan Ekmekcioglu, John B Mumm, Malini Udtha, Sunil Chada, Elizabeth A Grimm

Faculty, Staff and Student Publications

Restoration of the tumor-suppression function by gene transfer of the melanoma differentiation-associated gene 7 (MDA7)/interleukin 24 (IL-24) successfully induces apoptosis in melanoma tumors in vivo. To address the molecular mechanisms involved, we previously revealed that MDA7/IL-24 treatment of melanoma cells down-regulates interferon regulatory factor (IRF)-1 expression and concomitantly up-regulates IRF-2 expression, which competes with the activity of IRF-1 and reverses the induction of IRF-1-regulated inducible nitric oxide synthase (iNOS). Interferons (IFNs) influence melanoma cell survival by modulating apoptosis. A class I IFN (IFN-alpha) has been approved for the treatment of advanced melanoma with some limited success. A class II IFN …
