Development of a RAPTA complex synthesis and characterization lab for an upper-level inorganic chemistry course.
No full textRuthenium-arene-PTA complexes are rapidly garnering attention for their applications in medicinal chemistry. We have developed a multi-week teaching lab exercise conducted in CHEM 450 Advanced Inorganic Chemistry I in which students synthesize (p-cymene)(avobenzonate)(triazaphospha-adamantane)ruthenium(II) triflate as well as the triazaphosphaadamantane ligand itself. Characterization of the complex and ligand was completed using primarily NMR spectroscopy (1H and 31P) and mass spectrometry. Molecular modeling of NMR spectra have proven effective at the modest r2SCAN-3c level of theory, for accurately predicting chemical shifts. This lab development has paved the way for us to pursue new complexes with alternative β-diketonate ligands in lieu of avobenzone
Using the EPIC Algorithm for Radio Astronomy
Full text linkThe EPIC (E-field Parallel Imaging Correlator) algorithm is a direct imaging correlator for radio interferometer arrays. Bypassing the expensive processing step of cross correlation and immediately computing a spatial fast Fourier transform allows it to generate extremely high framerate radio images. EPIC serves to efficiently process signals from a very high count of radio antennas in an array with parallel computing, scaling as Nlog(N). This research project investigates the advantages and limitations of using EPIC for astronomy. This was done by stress testing both the user interface and back-end database through SQL commands to validate the output data it processed from the signal generated by the Long Wavelength Array radio telescope in New Mexico. The presentation provides an overview of how EPIC works, along with some projects that have been done such as documenting solar radio bursts, searching for fast radio bursts, and validating output via comparison to a beamforming algorithm

Setting Course for the Future at Westfield Golf Club
Full text linkWestfield Golf Course is a public golf course in Winona, Minnesota. Westfield opened for business in 1923 and is operated by Westfield, LLC, and overseen by a board of directors that ensures compliance with the terms of a deed for the land on which Westfield sits. The golf course has seen consistent success since its inception, but due to changing economics and increased competition, its membership has declined from a high of approximately 1,200 members in the 1980s to around 300 today. This project uses research and analysis to uncover strategic and creative solutions to address Westfield’s challenges. A review of applied research was conducted, and key insights revealed the need for Westfield to increase revenues and find additional funds for upgrades and repairs that need to be done. To develop the communication strategy, I relied upon Pat Jackson’s behavioral public relations model which converts attitudes and behavioral intent into action. Jackson’s model demonstrates how publics can progress from awareness to behavioral change through communication. Primary research included in-depth stakeholder interviews of golf club staff and board members and a member survey. The results were used to develop goals, objectives, and strategies included in a “Swing into Westfield” campaign with a detailed implementation plan and campaign evaluation. The campaign invites the community to experience Westfield’s golf course, bar and restaurant, and social opportunities. Implementation of these recommendations will ensure Westfield Golf Club remains financially solvent and continues operating

Project Compass: An Internship for the Able-Adults
No full textI will be discussing my time and activities with the organization named Project Compass and its associated activities. I plan on having a poster board, fliers and even past and future schedules that shows what project compass is about, their mission statement, and the activities clients and members of the organization can take part in. Aside from the physical board and fliers, I\u27m preparing to write a short speech or script that will be addressed to those interested, not only explaining the organization but also the benefits of being an intern there. As well as the many fun, and various activities the members and the intern will be able to partake in.
My research itself has been largely observation based, I have plans to acquire a few quotes from some of our clients and ratings also by the same clients behind the events that I\u27ve gotten the opportunity to take part in. thereby placing them on our pasteboard as a means of spreading awareness and giving validity to Project Compass as a future intern site for willing and curious students.
Lastly, in addition to the quotes, pictures, I plan to give my impressions and opinions on the experiences for the events I\u27ve gotten to take part in with Project Compass. Though I do not plan on quoting myself on my poster board, I do plan to elaborate on top of everything above by giving reassurance and personal confidence that this is an effective and fun site for future interns
Differences in Peak Relative Landing Forces in Division II Women’s Gymnastics, Basketball, and Soccer
Full text linkPURPOSE: Female athletes tend to be at high risk for lower limb injuries during non-contact landing. Relative peak landing force (RPLF) is the metric being monitored in this study to compare landing forces among three different women’s sports teams. RPLF is the amount of force the athlete is landing with compared to their body weight. This gives insight into athletes that could be at risk for lower limb injuries. METHODS: 16 gymnasts (height: 163.04 ± 4.84cm; BW: 62.17 ± 5.01kg) from the Winona State University gymnastics team participated in five weeks of countermovement jump (CMJ) testing using two force plates with a sampling rate of 1000 Hz. The gymnasts were tested twice a week for a total of 8 testing sessions. This study excludes participants who were injured, who missed two or more testing sessions in a row, or had frequent variability in their jump data causing inconsistent data for that athlete. The data was tracked and exported to a customized spreadsheet to compare with the Winona State University women’s soccer (height: 167.96 ± 4.63cm; BW: 66.38 ± 9.31kg) and basketball (height: 177.8 ± 4.70cm; BW: 73.15 ± 6.49kg) CMJ data that was previously collected using the same protocol. SPSS was used to calculate descriptive statistics and group differences in RPLF using one-way ANOVA. Bonferroni post hoc tests were used to analyze differences between groups. A significant value of p\u3c 0.05 was set for all analyses. RESULTS: A significant group difference in RPLF was found among women’s sports (p= 0.021). A significant difference in landing force was found between gymnastics and basketball (p-value = 0.026, d = 4.60). However, there was no significant difference in landing force found between gymnastics and soccer (p-value = 1.000, d = 1.198) or basketball and soccer (p-value = 0.092, d = -3.35). Gymnastics showed higher RPLF with a group mean of 473.40 ± 11.15N/kg. Soccer landed with a group mean of 455.21 ±18.36N/kg. Basketball had a lower RPLF with a group mean of 377.14 ± 27.43N/kg.
CONCLUSION: The findings in this study show that gymnasts and soccer athletes tend to land with more force compared to basketball athletes. High landing forces can have a large impact on the lower body, leading that athlete to be at a higher risk of injury
