Synthesis of alpha- heteroaryl Compounds via Palladium Catalysis in Course-based Undergraduate Research Experience (CURE) Organic Lab
No full text2020 Celebration of Student Research and Creativity presentation" Heteroaryl compounds are common and important components in medicinal chemistry. A palladium catalyzed α-heteroarylation of the compound tropinone under microwave irradiation was conducted in our lab. In this presentation, the palladium catalysis was utilized to synthesize α- heteroaryl compounds. The optimized reaction conditions are 1.1 equivalents of tropinone, 1 equivalent of heteroaryl halide, 2.4 equivalents of NaOtBu. 2mol% of XPhos Pd, in a 2mL toluene solution under microwave irradiation for 20 minutes at 1500 C. This study provided data and information for the development and manufacture of new heteroaryl compounds as cancer treatment candidates."https://nku.voicethread.com/share/16257715
Implications of Cultural Norms for Women in Leadership Around the World
No full text2020 Celebration of Student Research and Creativity presentation"While women have strived to be equals in the workplace for years, it is still an ongoing battle. This is not only true in America, but in most countries around the world as well as most job fields. Women are consistently overlooked, underpaid, underrepresented, and misunderstood. To gain better insight into the specific struggles of women in the workplace a literature review was conducted to explore existing research and identify the treatment of women in the workplace and the challenges they face, and related experiences in leadership. To gain a global perspective, experiences of women leaders in North America, Asia, and Europe
were explored."https://youtu.be/xJJIb7zPVN
Transforming Geosciences Education Through Immersive Virtual Reality
No full text2020 Celebration of Student Research and Creativity presentation"With the Covid-19 pandemic, the need for easy to implement solutions to enhance online learning is paramount. With more lockdowns on the way, I have created an example of a workflow that any NKU staff could follow to create a virtual field trip or immersive 3D lecture using inexpensive and available Google Cardboard VR and YoutubeVR as well as the Vuze XR Camera."https://youtu.be/bRKkCCqNrM
Phosphoenolpyruvate carboxykinase genes may play critical role in embryonic development
No full text2020 Celebration of Student Research and Creativity presentation"During development, cells in vertebrate embryos differentiate to form adult tissues and organs. Many genetic signaling pathways are used by cells to communicate and coordinate their development. If these genetic signals are disrupted, birth defects can result. We identified two genes from the pck (phosphoenolpyruvate carboxykinase) family that were potentially being expressed during embryonic development. We analyzed pck gene expression with in- situ hybridization and determined the tissue layers the pck genes were expressed in by sectioning the embryos. Our results show that pck1 and 2 are expressed in the ectoderm, a tissue that forms the skin and nervous system, suggesting that these genes may play important roles in the development of the skin. Moreover, amino acid alignments of the pck genes from multiple species were completed, identifying considerable similarities in protein domains. These results contribute to our understanding of the evolution and roles the pck genes play during embryonic development."https://youtu.be/-iUFXiB4oC
Bone Histology Analysis of Ceratopsian Dinosaur Einiosaurus Growth Curve
No full text2020 Celebration of Student Research and Creativity presentation"Paleohistology, the study of microscopic anatomy of fossil organisms, has been on the forefront of paleontological research for some time now. The
microstructure of fossils lends evidence into how a dinosaur, or even a population of dinosaurs could have survived, grown, lived, and died (Chinsamy, 1995). The way the bone is formed can act as evidence for how Einiosaurus grew as they aged. Highly vascular tissue and dense osteocytes (bone cells) is evidence for rapid growth in a sample specimen and also imply an elevated metabolism (Levitt, 2013: page iv), whereas sparse vascular tissue and light osteocytes would imply slow growth. The question we were asking is ‘What does the orientation and density of osteocytes and vascular canals in these limb bones tell us about the physiology of this species of dinosaur?’. Using Adobe Illustrator we were able to standardize the samples and categorize the amount of vascular canals in each specimen. This resulted in Tibia 6 and 10 showing the most rapid growth, and Tibia 14 showing the slowest growth. The results of this study do not concur with Reizner’s original growth curve, and thusly further
studies prove necessary."https://youtu.be/KNPNcl41au
A variation of Cops and Robbers on Graphs
No full text2020 Celebration of Student Research and Creativity presentation"We consider a variation of game of cops and robber where the cop seeks to determine the location of the robber by selecting a vertex v in the graph and receiving distance from v to the invisible robber. The movement of robber is restricted to adjacent vertices except for the vertices just probed by the cop. We use multiple probes per turn for the cop to determine strategies to locate the robber in the Gr otzsch graph, the Petersen graph, and split graphs and conclude that it takes at most 3 turns to locate the robber in Gr otzsch graph and the Petersen graph. We also provide strategies to locate robber on different split graphs"https://youtu.be/ZxEjlkUYA2
Fine Tuning Performance and Efficiency of Virtual Infrastructure
No full text2020 Celebration of Student Research and Creativity presentationThis is a study of virtual infrastructure performance. We intend to develop methods to correctly size virtual machine resources according to its workload. We will attempt to optimize virtual machines over four different resource categories: CPU, storage, memory, and network. We will host virtual machines and modify parameters per machine while monitoring its workloads. The results will show performance differences between optimized and default resource allocations. The implications of these results can result in increased cost and energy savings for infrastructure providers.https://youtu.be/eFoI-SMbDL
Combating Human Trafficking
No full text2020 Student Celebration of Research and Creativity presentationHuman trafficking has grown into an out of control problem here in the United States of America. Unlike most crimes and problems that the United States face human trafficking is one of those problems that can affect anyone at any time. Despite the government other organizations help and even individuals the Human trafficking crisis keeps Growing. How do we as Individuals, communities, and a nation stop this horrendous act. I will propose a holistic and viable solution that will use the disciplines of Business Administration, Organizational Leadership, and Biblical Studies. https://youtu.be/KQ2arzSsmC
Differential Photometry Image Processing with the NKU 14-inch Telescope
No full text2020 Celebration of Student Research and Creativity presentationNKU’s Schneider Observatory, located on campus atop Founder’s Hall, features a 14-inch Schmidt-Cassegrain telescope mounted on a German equatorial mount with computer control capabilities. This telescope was brought online over the summer of 2019. The larger size of this telescope coupled with a SBIG STT-3200ME CCD and Johnson filter set, allows us to do precision differential photometry of variable objects. As part of testing the system’s differential photometry capabilities, we took data on several targets, including variable stars and transiting exoplanets.https://youtu.be/PamqHyrKQb
