Effects Of Novel Tool Use: Cortical And Functional Measures In Children Using A Prosthetic Simulator, Chris Copeland

UNO Student Research and Creative Activity Fair

As of 2005, there were a total of 1.6 million people living with the loss of a limb, with this population projected to double to 3.6 million by 2050 [1]. While prostheses aim to enhance the function of these individuals, it is estimated that 45% of pediatric prosthetic users reject their prosthesis [2]. The literature which describes the neurological control mechanisms of prosthetic use is sparse and often low-powered due to an inadequate number of participants. However, prosthetic simulators may be a solution to chronically low-powered prosthetic-centric studies by serving as functional homologues, though this has yet to be tested. …

Amino Acid Quantification For Dmc Biotechnologies, Russell Beckerman, Rebecca Hines, Kenya Jacob, Megan Mccabe, Ju Yun Lee

ENGS 89/90 Reports

From pharmaceuticals to biofuels, fermentation bioprocessing has gained traction in many industries reaching a global market value of almost $60 billion in 2018. However, applications of bioprocessing have been limited in scope due to high capital costs, long development times, and difficulties maintaining productivity during scale-up. Furthering development and scale-up of fermentation bioprocesses require careful monitoring and control through analytical chemistry. Currently, there are no small molecule quantification techniques that are sufficiently accurate, inexpensive, and high-throughput. This investigation explores viability of a novel quantification assay for amino acids in fermentation broth leveraging molecularly imprinted polymers (MIPs) and gold nanoparticles (AuNPs).
