It’s Not Busy Work
Get PDFIn the wake of the COVID 19 pandemic at Kansas State University many library employees needed to be able to do work from home or risk the prospect of not getting paid. The university archivist and the web services librarian got together to develop digital projects that could be completed without any special equipment other than a computer and internet. These projects benefited the university archives by making history more accessible and visible to others. We will show the processes that were used, the final product, and feedback from a library employee who worked on these projects

Synthetic Efforts Towards the Lagunamide and Chalcone Based Natural Products
Get PDFRyan RaffertyThe Lagunamides are a series of secondary metabolites produced by marine cyanobacteria that possess almost identical polypeptide and polyketide moieties and display potency against various cancer cell lines. They are differentiated by the side chain on the polyketide moiety. Chalcones are a class of molecules characterized by an α,β-unsaturated ketone moiety and adjacent phenyl groups; some species that fall under this classification have displayed a similar efficacy when tested against various cancer cell lines. Synthetic procedures on a 100 mg scale and their associated mechanisms regarding the construction of Crimmins’ auxiliaries (yield = 72%), diazotization of D-alloisoleucine (yield = 40%/35% for 300 mg scale), and the esterification (yield = 72%), Boc deprotection (yield = 84%), and first peptide coupling (yield = N/A) in the formation of the polyketide moiety of Lagunamides are discussed. Furthermore, the synthetic procedure and mechanism for the acylation (yield = 24%) and subsequent methylation (yield = N/A) of phloroglucinol are provided. For the unsuccessful peptide coupling reaction, the most likely point of failure was the lack of carboxylic acid activation by EDC. For the unsuccessful acylation of phloroglucinol, consideration of the kinetics of aromatic substitutions and the NMR spectrum of the product indicated that diacylation had occurred (the desired product was monoacylated)
Inner-Shell-Ionization-Induced Femtosecond Structural Dynamics of Water Molecules Imaged at an X-Ray Free-Electron Laser
Get PDFThe ultrafast structural dynamics of water following inner-shell ionization is a crucial issue in high-energy radiation chemistry. We have exposed isolated water molecules to a short x-ray pulse from a free-electron laser and detected momenta of all produced ions in coincidence. By combining experimental results and theoretical modeling, we can image dissociation dynamics of individual molecules in unprecedented detail. We reveal significant molecular structural dynamics in H2O2+, such as asymmetric deformation and bond-angle opening, leading to two-body or three-body fragmentation on a timescale of a few femtoseconds. We thus reconstruct several snapshots of structural dynamics at different time intervals, which highlight dynamical patterns that are relevant as initiating steps of subsequent radiation-damage processes
Potential nutrition contributions to exercise-associated muscle cramping in four recreational half-marathoners: A case series
Get PDFObjectives: Nutrition-related practices and outcomes vary dramatically between athletes, and traditional beliefs regarding the role of electrolytes and hydration in exercise-associated muscle cramping (EAMC) may be hindering meaningful prevention strategies. The aim of this study was to characterize the role of carbohydrate (CHO), energy, and exertion level, in conjunction with electrolyte and hydration status to assess the role of these possible predictors of EAMC.
Methods: A case study series approach was used to capture pre-race and on-course food and beverage intake, pre and post-race body weight, relative perceived exertion (RPE), and history of EAMC for four recreational runners prior to and during a half-marathon race.
Results: CHO intake, energy intake, and hydration status varied among the runners with one occurrence of EAMC. Reported pre-race CHO intake for all but one runner fell below 5 g/kg/day. Weight loss during the race was between 1.23-3.03%. Two of the four runners reported a prior history of EAMC, one of which experienced EAMC during the race. The two runners with a prior history of EAMC, also reported the lowest 3-day energy and CHO intakes. The one runner who encountered an EAMC did not experience the greatest net race sodium loss. However, this runner did have the greatest race weight loss, the greatest race sweat loss, the longest duration of activity, the lowest RPE, and suboptimal energy and CHO intakes.
Conclusions: The observed case of EAMC does not appear to be entirely inconsistent with the traditional dehydration/ electrolyte loss theory. However, the in-depth characterization of each runner illustrates the complex interaction of potential predictors and also generates questions regarding the potential contribution of suboptimal energy and CHO intakes
Enhancing Financial Literacy among College Athletes
Get PDFCollege students, including athletes, have limited exposure to financial education prior to enrolling in college (Britt et al., 2015). Athletes juggling two full-time roles as athlete and college student have limited time for financial education and the opportunity to work. Some athletes receive athletic scholarships and some do not, but either way, many athletes must seek additional funding and student loans to pay for college. Huston’s (2010) model demonstrated connections between financial literacy, behaviors, and education to serve as a framework for our study. The purpose of this study was to determine college athletes’ subjective and objective financial literacy, how they applied this knowledge, and their preferred mode(s) of financial education to pilot financial literacy education geared specifically for athletes based on their preferences. Data was collected from two institutions in the same Power 5 conference: monthly spending logs, focus groups, interviews, a financial knowledge survey, and pre- and post-tests flanking a financial literacy module in first-year experience courses and summer bridge. A Money 101 course was piloted over eight weeks, and peer financial counseling was offered. As athletes might gain access to their name, image, and likeness (NIL) for potential income in the near future, financial education is paramount

XUV-Initiated Dissociation Dynamics of Molecular Oxygen (O2)
Get PDFWe performed a time-resolved spectroscopy experiment on the dissociation of oxygen molecules after the interaction with intense extreme-ultraviolet (XUV) light from the free-electron laser in Hamburg at Deutsches Elektronen-Synchrotron. Using an XUV-pump/XUV-probe transient-absorption geometry with a split-and-delay unit, we observe the onset of electronic transitions in the O2+ cation near 50 eV photon energy, marking the end of the progression from a molecule to two isolated atoms. We observe two different time scales of 290 ± 53 and 180 ± 76 fs for the emergence of different ionic transitions, indicating different dissociation pathways taken by the departing oxygen atoms. With regard to the emerging opportunities of tuning the central frequencies of pump and probe pulses and of increasing the probe–pulse bandwidth, future pump–probe transient-absorption experiments are expected to provide a detailed view of the coupled nuclear and electronic dynamics during molecular dissociation
