Ball milling is used in industry to grind ores, minerals, ceramics, and recently has been implemented to research synthesis of organic compounds. One project is researching nickel catalysis in high speed ball milling for producing substituted cyclooctatetraene compounds. In the process of synthesizing the compounds, Ni, Cr, and Fe residues from the vials and nickel pellets used for the reaction will remain in the product. To analyze for the metals remaining in the product, Inductively Coupled Plasma paired with Mass Spectrometry was used. Initially used as an internal standard, gallium’s mass was found on the spectrometer. It is suspected to be a false positive caused by a FeO+ or FeN+. The product was analyzed using Agilent Technologies 7700 ICP-MS before and after a filtering process. This helped determine how effective the filtering process was removing metals and what concentration remained at the part per billion level (ppb) in the final product. A calibration curve was made with a blank, 1ppb, 5ppb, 10ppb, 25ppb, and 50ppb with Sc as the internal standard. Results showed that chromium is insignificant (<0.0ppb), and iron is approximately 1ppb in concentration. Before the filtration process, nickel is approximately 10ppb, after filtration, nickel’s concentration is insignificant (<0.0ppb).
This project aimed at effectively implementing eye tracking MATLAB. The team created an eye tracking program that uses a webcam to locate where a person is looking on a computer screen. The program was tested with a simple experiment that presented the user with a set of colors and found which colors the user looked at most.
Improper phlebotomy practice is among one of the most important, and more so, overlooked issues in laboratory medicine. Lab practices involving phlebotomy are critical for diagnostic purposes as erroneous results from incorrect collection can result in potentially life threatening misdiagnoses or treatment routes. This pre-analytical error can result in misleading hyperkalemia and hypocalcemia illustrated in otherwise healthy patients. Improper order of draw can incur costs for both the patient and healthcare facility. Preventative measures must be employed to reduce such adverse events from reoccurring as this singular error can lead to a domino effect of continuous error if not recognized and investigated.
The purpose of this project was to develop a method to characterize polymers using size exclusion chromatography. Specifically, high performance liquid chromatography coupled with a refractive index detector (RID) was used. Polyethylene glycol (PEG) was used a standard for this method. The mobile phase used was dimethylformamide (DMF). Three different mixtures of PEG polymers with known molecular weights were analyzed to characterize the molecular weight of polyacrylic acid (PAA). After running all polymers, retention times were taken and plotted on the x-axis along with LogMp (molecular weight) on the y-axis. A calibration curve was created and plugged in the retention time of PAA to the line equation. We then, took 10 to the power of that number and calculated a molecular weight of 52292.97 g/mol. This method was shown to be an effective way to characterize polymers using PEG as a standard. Poly (methyl methacrylate), otherwise known as P(MMA), was also tested using the same method. The known weight of the polymer was 60,500 g/mol. After running the polymer, 23,000 g/mol was calculated to be the molecular weight. This molecular weight shows that certain parameters like polarity needs to be considered when running samples on the HPLC.
UC SCHOOL OF ART MFA GRADUATING SHOW 2015 — TEXTS AND PROJECTS
This collection of texts and images brings together the work of graduate students and faculty in art history, art education, and fine arts at the University of Cincinnati in the spring of 2015. We invited students in art education and art history to write accompanying texts for the final projects of their peers in the fine arts graduate program – projects encompassing everything from multimedia installation, abstract painting, video animation, fiber-based sculptural assemblages, photography, and drawing. The students’ projects were presented at the Contemporary Arts Center, Cincinnati, as part of the School of Art’s MFA Thesis Exhibition, which ran from April 1 and April 25, 2015. A process of looking, talking, looking again, writing, reading, and re-writing unfolded. Shorter versions of the texts were shown at the CAC alongside the artworks at the CAC. The process created a working space for artists and writers in dialogue, giving rise to new ideas and projects in turn.

Neonatal Brachial Plexus Injury (NBPI) is a common birth injury to the nerves innervating the upper limb. A poorly understood and currently incurable consequence of this injury is tightness of affected muscles, or muscle contractures. Paradoxically, contractures do not occur in a rare form of NBPI (preganglionic) in which afferent (sensory) innervation of the muscle is preserved, in contrast to the more common postganglionic NBPI which causes complete denervation, suggesting a possible role of afferent denervation in contracture formation. Afferent neurons interface with muscle at the spindle and golgi tendon organ (GTO). Previous studies have implicated muscle spindles in contracture formation, but the GTO has not been investigated. Unilateral pre and post-ganglionic NBPIs were created in neonatal mice. Bilateral biceps muscles were harvested four weeks later, cleared, and immunohistochemically stained in whole mounts to assess GTO morphology. The nerves innervating the biceps were sectioned and stained to quantify afferent denervation. Complete denervation by postganglionic NBPI led to loss of GTO in denervated muscles, whereas preservation of afferent innervation in preganglionic NBPI preserved normal GTO morphology. These findings suggest that afferent innervation is required for postnatal GTO maintenance, and that loss of the GTO may play a role in contracture formation.
