Ribbon Synapses\u27 Role in Synaptic Identification
Get PDFUnderstanding the impact of presynaptic and postsynaptic structures on synaptic strength, neurotransmission speed, and morphology is crucial. When cone photoreceptors transmit light-driven signals to cone bipolar cells, various presynaptic structural arrangements can be observed, featuring different numbers of synaptic ribbons. These ribbons facilitate faster initial excitation and sustained transmitter release as vesicles dock at ribbon synapses.
To investigate these structures, I will use the WEBKNOSSOS program to trace dendrites in vertebrate retinal images, determining the number of ribbon synapses and neuron types. This research, building upon the work of Dr. Wan-Qing Yu and Swanstrom, is expected to take about a month. The outcome will be a comprehensive paper outlining the methodology, findings, and implications of identifying neurons based on their synaptic arrangements, ribbons, and dendritic tracings.
This project enhances my college curriculum by providing hands-on research experience, consolidating knowledge in biology and neuroscience, and honing practical skills. It integrates insights into neurotransmission and synaptic functions, contributing to a holistic understanding of neuron function and structure
Short Strand Carbon Fiber Reinforced Polylactic Acid Filament for Additive Manufacturing
Get PDFIn this design project, the additive manufacturing filament of short strand carbon fiber (SSCF) reinforced polylactic acid (PLA) composite was developed. The micro-size, precision cut SSCFs were mixed with the PLA pellets through a melting homogenization process. Through this process the composite material block is cut and divided into pieces for ease of pelletizing. The material block pieces are then pelletized to be fed through the single screw extruder to develop the SSCF-PLA composite filament. The SSCF-PLA filaments were manufactured with a varying amount of SSCF ranging from 0.5% to 10% of the material block\u27s weight. Development of a 1% by volume material block was achieved however proved to introduce more inaccuracies in the process when compared to the percentage by weight manufacturing method. The SSCF-PLA composite filament was then fed through a 3D printer to produce samples. The developed composite filaments with different SSCF contents were studied by analyzing their physical and mechanical properties. The SSCF-PLA filament composite was analyzed throughout each stage of the manufacturing process to ensure a homogenous blend of the composite. The developed composite filament has shown a reduction in yield strength (when compared to standard PLA) as there was an increase in SSCF percentage by weight. However, the amount of moisture introduced to the composite through the manufacturing process caused the composite to decrease the printability of the developed composite as the SSCF percentage by weight increased in the developed composite samples

Schaeffler iCVD Coating Machine
Get PDFChemical Vapor Deposition (CVD) is mutual technology used to deposit thin film through a gaseous phase by vaporizing the solid materials. This conventional process usually requires high thermal stability of the materials, which is not applicable for most of the polymeric materials. Therefore, a novel process, initiated Chemical Vapor Deposition (iCVD) is developed by introducing the gaseous monument and initiator to form the thin film in-situ. By adjusting the free-radical polymerization in the vapor phase, a variety of thin and uniform polymer films can be achieved. Depending on the chemistry, iCVD has many categories. This report explains the design and assembly process of an iCVD machine to meet the company’s applications for polymer thin film deposition. The mass flow controlling, thermal management and vacuum monitoring system have been successfully designed and built. This enables the precise control the gaseous reactant feeding and film deposition rate. Meanwhile, the machine is mobile and modular, allowing for easy movement in the lab environment and future upgrades. The device will be used to characterize polymer coatings for use in coating metallic anode battery components to counteract harmful side reactions, thus increasing the feasibility of large-scale metallic anode solid-state battery production
Asynchronous Class for Algebra I Preparation
Get PDFAlgebra I is the first high school mathematics class students take making it an important building block in the student’s growing mathematical foundation. Mitigating any losses in knowledge over the summer by using educational review tools has been proven helpful in previous studies. Every student comes from a different background, socioeconomic class, ethnicity, culture, etc., allowing each student to have a different summer experience. A meta-analysis looking into the concern of Summer Learning Loss (SLL) found that while some of its sample size would make summer knowledge gains, more than half of the sample size was projected to suffer from SLL (Atteberry & McEachin, 2020). This emphasizes the need to close the gap between these two groups. One study focusing on younger students, found that after implementing a math app regime for twelve weeks, the children demonstrated greater math learning improvements compared to the control of no app usage (Outhwaite et al., 2019). This information can be applied to Algebra I. Utilizing a summer mathematical course can be hypothesized to mitigate SLL in pre-algebraic content and leave students better prepared for Algebra I. Based on the Common Core State Standards and the Ohio Learning Standards for Mathematics, a basic outline of an asynchronous Algebra I preparation summer course was Developed. The course uses Desmos Classroom to deliver 6 lessons. These lessons are created to review knowledge learned throughout middle school mathematics to prepare students for Algebra I and to give teachers insight into any gaps in knowledge the students may have
Gait Kinematics in Sled Dog Fitness
Get PDFThe sport of sled dog racing has become popular in recent years, where teams of dogs navigate Arctic conditions anywhere from a few hundred to a thousand miles, usually within 10 days. To prepare for these competitions, dogs are subjected to rigorous training months prior to the race that results in significant changes to the physiology of their bones and muscles. This study aims to determine differences in gait kinetics between female and male sled dogs. Ten dogs, five females and five males, were recorded trotting from a lateral view for three weightbased trials to simulate different amounts of weight pulling on the harness. Markers were attached to dogs at major anatomical landmarks to determine 2D joint angles. The hypothesis tested was that female dogs will have significantly different joint angles, specifically at the shoulder and carpus (i.e., wrist), than male dogs. Mixed effect models with repeated measures on the individual were performed. Results indicated a significantly smaller maximum joint angle of the carpus in female dogs compared to males at 9 lbs of pulling pressure, similar to what is experienced while racing. No other significant results were reported, only partially supporting the hypothesis. Limitations include the lack of accounting for differences in conformation while standing in different individuals, variables such as age, and imperfect reflection of the dog’s attitude and performance while collecting data in a laboratory setting. These findings can aid in creating appropriate training regimens that reduce injuries and improve fitness of working dogs from any background

Development of a SolidWorks API
Get PDFWith the current advancements in CAD software, and precision of modern motors, we believe that a new way to communicate from hardware to software is possible. This report details the steps we have taken to attempt just that. The essential idea behind this is that modern controls for robotics are not as user friendly as they can be. The general action taken is to create an API for SolidWorks that connects it to the other necessary controller software and makes it so that a robot, and its exact current position, can be changed simply and intuitively from SolidWorks. Furthermore, the implemented software should be able to track and detect any changes made to the real-world device, and update the exact same device moves up in SolidWorks to the exact same changed metrics. The ideal outcome is a user-friendly experience that allows for intuitive and simplistic implementation and learning of robotics
