    Tympanostomy Tube Efficiency Study

    Get PDF
    The ventilation of the middle ear, crucial for maintaining optimal ear health, is often impeded by factors such as swelling, inflammation, and mucus in the eustachian tubes, particularly during upper respiratory infections or allergies. This issue, prevalent in children due to their narrow and horizontal eustachian tubes, prompts the insertion of tympanostomy tubes by ENT surgeons to establish an alternative airway for pressure equalization and fluid drainage. Despite the common belief in the effectiveness of these tubes, there is a notable dearth of research validating their optimal functionality. This study aims to address this gap by systematically comparing the efficiency of various ear tubes available in the market, considering metrics such as material, length, diameter, and additional features. The experimental approach involves using a video camera to observe the inflow and outflow of liquid droplets introduced into the ear tubes under diverse conditions. Post-processing of the gathered data will inform insights into potential enhancements for optimal ear tube design. Subsequent to data evaluation, new ear tube designs will be developed using Computer-Aided Design (CAD), 3D printed, and subjected to rigorous testing and validation. The ultimate objective is to create an improved ear tube design that not only facilitates efficient drainage but also ensures a high success rate of eardrop inflow, contributing to advancements in ear health interventions

    “Breathe Easy and Get A Good Night Sleep” : Exploring Parental Relationships in Hardship

    Get PDF
    This project explores parental relationships with a focus on mother-daughter relationships. I want to focus on the attachment between a parent and a child, and how mental illness and abuse from the other parent affect that relationship. This project derives from a deep love for my mother and the changes between us that I noticed as I grew older. I hope to create a choreographed work that explores our relationship with a hope of creating a stronger bond that suits our new relationship and who we are as people now. I want this dance to aid in our reconnection. I will include academic research on parental relationships that gets integrated into the choreography, but I chose dance as the main method of exploration and research because a research paper alone will not do this topic justice. This topic has emotions, stories, and entire livelihoods involved, and dance is a great way to explore and portray these elements. This project will be an intersection of academic research and the ways choreography can be a medium to bring that research to life

    Restoration for The Small and Slimy: How Pond-breeding Amphibians Utilize Natural, Restored, and Created Wetlands

    Get PDF
    This research project for the Williams Honors College sought to examine how local pond-breeding amphibians utilized natural, restored, and created wetlands. Presence/absence data was gathered from field surveys, historical records, and iNaturalist data for the six study sites. It was predicted that created and restored wetlands may support less sensitive species with lower coefficient of conservatism scores, based on past surveys of a similar nature. No statistically significant results were found in this survey, but that could be due to low sample sizes and limited data sets, among other considerations. Therefore, more in-depth studies should still be undertaken to examine this question in our local ecosystems. Restoration and habitat creation are becoming more common practices as natural spaces are lost and climate change worsens. When restoring and creating wetland habitat, more considerations should be made for sensitive, pond-breeding species, and extra care should be taken to not cause harm via hydrology changes, human disturbance, introduction of predatory species, etc. In Ohio, our wetland protections and restoration practices likely need an overhaul to truly support and protect sensitive, pond-breeding amphibian species

    The objective is to build a scaled down model of a 3D printed drone capable of carrying a payload scalable to 50 lbs. for a wide array of applications. Some applications of the drone could include delivering support materials during natural disasters, such as foam to put out fire or medical aid packs to provide aid to injured people, food or package delivery, or military applications. The project has been split up into two groups. One group will be focusing on the propulsion aspect of the project, such as the electric motors and airfoil. Simultaneously, this group will design the body and control aspects of the drone, such as the structure, circuit board, and software. The manufacturing method of 3D printing has been chosen to study and address the various challenges associated with it and to prove this concept can be easily manufactured if critical parts are damaged or need replaced in the remote, emergency locations that the drone may be used in

    Sources and Termination Patterns of Cholinergic Input to the Ventral Nucleus of the Lateral Lemniscus

    Get PDF
    Neurons transmit signals through an electrochemical reaction: synapses on dendrites and the cell body receive neurotransmitters, and their effect on the cell determines the signal the cell will transmit. From dendrites to axon and then to another cell at a synaptic cleft, signals can propagate, enhance each other, or inhibit other transmissions until the message is received by the target area. Understanding the science behind neural signaling and structural function begins at the level of the synapse. The neurotransmitter acetylcholine (ACh) plays a substantial role in modulating neural activity in the auditory system, but for many brainstem nuclei the source of cholinergic input is unknown. Identifying the source of ACh holds such significance because different sources are likely to perform different functions. The present study categorizes cholinergic input to the Ventral Nucleus of the Lateral Lemniscus (VNLL), one of the largest sources of inhibitory input to the Inferior Colliculus (IC), a midbrain center that processes nearly all auditory information received by the brain. Using retrograde and anterograde labeling of cholinergic cell bodies and axons, we identified three regions- the Pontomesenphalic Tegmentum (PMT), the Superior Olivary Complex (SOC), and the Lateral Paragigantocellular Nucleus (LPGi)- transmitting acetylcholine to the VNLL in mouse. Mouse models allowed for selective manipulation of cholinergic axons through viral injection of fluorescent protein in transgenic-bred mouse lines. Retrograde experiments identified cholinergic cell bodies in the three regions of interest communicating with the VNLL by labeling cells with a RetroBead marker originally injected into the VNLL followed by antibody tissue staining, and anterograde studies validated this communication pattern by labeling cholinergic axons in the VNLL coming from fluorescent injections placed in each of the three regions of interest. Axon termination patterns demonstrate the degree of communication between these areas and also suggest that individual VNLL neurons receive converging input from multiple cholinergic sources, likely to be active for different roles in modulating VNLL neurons and their responses to sound
