Differences in Open-Canopy Foraging Behaviors that Influence Resource Partitioning Between Three Tyrannidae Species in Monteverde, Costa Rica
No full textAnimals that inhabit the same space will modify their behaviors to reduce competition. Coexisting flycatchers often differ in their foraging behaviors. Our study sites were pastures in and around the University of Georgia: Costa Rica in Monteverde. We analyzed foraging behaviors of three flycatcher species by recording: technique, prey size, perch height, and zone usage (parts of the pastures most frequented). We hypothesized that flycatchers would exhibit unique preferences in regards to technique, prey size, perch height, and zone usage, exhibiting resource partitioning. Tropical Kingbirds, Dusky-capped Flycatchers, and Social Flycatchers showed significant differences in foraging technique. Prey size choice was significantly different, mean size correlating with bill length for each species. There was a significant difference between the amount of times each bird visited each zone (core v periphery). The data showed a trend in the reduction of appearances of kingbirds moving out from the center zone contrasting with increased appearances of dusky-capped and social flycatchers in the outer zones. We saw no significant difference in perch height, but our findings suggest resource partitioning amongst the species. Our data corroborate previous studies and will provide better background into foraging behaviors of similar species

Elderberry Extract Modifies the Proteostasis Network and Extends Lifespan in C. elegans
No full textThe degradation of the proteostasis network (PN) is indicative of several age-related diseases. A common theme in these diseases is the buildup of the toxic amyloid beta (Aβ) oligomer. Treatment of elderberry extract (EBE) provides significant lifespan extension to C.elegans; however the mechanism of lifespan extension has remained unclear. Several genetic variations in the Insulin/IGF-1 Signaling (IIS) have also lead to a significant extension of lifespan. Thus, knockdown of several genes in the IIS Pathway may elucidate the desired target for lifespan extension. Western blot analysis will demonstrate the effectiveness of EBE treatment by displaying reduction of Aβ. Understanding the mechanism behind EBE’s effect may open new doorways to preventative treatments of many age-related diseases
The Effects of Delayed Bathing in Full-Term Vaginally Delivered Newborns
No full textDiscrepancies are evident in the clinical setting regarding recommendations for timing of first newborn bath. Research aimed to answer questions regarding effects of delayed bathing to at least twelve hours of life. Data found through literature review supports that there are several benefits to delayed bathing. The purpose of this study was to explore the value of delayed bathing in full-term vaginally delivered newborns. The method of this study was a literature search using CINAHL and Google Scholar databases with use of 11 articles. This review shows implementation of delayed bathing is associated with increased breastfeeding rates, thermoregulation and blood sugar control, as well as increased maternal/newborn bonding
Identifying Patterns in Modular Arithmetic
No full textIs it ever true that 2+2 = 0? It is true under addition modulus 4. There are some very distinctive patterns in modular arithmetic, and we can visualize these patterns in modular multiplication tables. For example, we observe an inverse pattern in the columns of modular multiplication tables. Additionally, we prove a generalized formula for these patterns in any modulus. Ultimately, we identify many patterns that lead to much more complex and insightful formulas
Influence of Large-Scale Regime Transitions on Atmospheric River Events over Western North America
No full textThe Pacific-North American pattern (PNA) is a teleconnection pattern that characterizes mid-tropospheric flow configurations over North America that can have profound implications regional weather and climate response. Multiple studies have investigated how different phases of the PNA can influence atmospheric river (AR) events over western North America, however, the relationship between PNA regime transitions and AR events has not yet been explored. In this study, archived daily PNA values from the CPC are cross-referenced with NCEP sub-daily IVT along the western North American coast to construct time series analyses of PNA transitions and the resulting AR day likelihoods during the winter months. Analysis of the time-lagged transitions illustrate enhanced likelihoods of AR days along the Pacific Northwest (California and Oregon) coast during positive-to-negative (negative-to-positive) pre- and mid-transition phases as well as negative-to-positive (positive-to-negative) post-transition phases. Enhanced precipitation and streamflow response are confined to the northern U.S. West Coast for the majority of P2N transition duration while the effects are more pronounced and shifted southward for the majority of N2P transition duration. Future research efforts will investigate the forecast reliability of regime transitions and the conjunction of PNA transitions with other teleconnection pattern transitions, such as the Eastern Pacific Oscillation
Business Analysis of The New Hampshire Grand Hotels
No full textOver the course of the semester Dr. Roxana Wright\u27s Strategic Management class from the Business Department here at PSU has been working on a project that investigates the business side of The New Hampshire Grand Hotels. Much of the research focuses on future outlooks of the industry and covers a variety of different topics such as core competencies, recommendations on business practices, consumer demographics, and even industry characteristics. Formal business reports have been constructed as well as artifacts highlighting key statistics and information. All of this work will be up for display in the Museum of The White Mountains here in Plymouth upon completion of the project. This project is the culmination of 4 years of education across various business majors collaborating on one final project
The Effects of Personal Care Product Toxins on Locomotion in Limulus polyphemus, the American Horseshoe Crab
No full textThe Legend of Question Six
Get PDFThe final question 1988 International Math Olympiad in Melbourne Australia, presented to the world’s best and brightest young minds, would evolve to become one of most difficult questions in Mathematics. Of the 260 participants, only eleven were able to solve Question Six perfectly in the given amount of time, proving too difficult even for future Field’s Medalist Terence Tao. Question Six simply states “Let a and b be positive integers such that ab + 1 divides a2 + b2. Show that the resulting integer is a perfect square”. This research explores a definitive solution to the infamous question, and features questions utilizing a similar train of thought, featuring an emergent proof technique that is new to the world of Mathematics
