Optimizing A Perfusion-Compression Bioreactor Via Python Integration, Umamah Amer

Honors Theses

Bioreactors are widely used in tissue engineering to support cell and tissue growth under controlled conditions. Perfusion-compression bioreactors, like the one developed in our lab, can be used to replicate the physiological loading of bone on 3D-printed scaffolds. When seeded with osteogenic cells and subjected to mechanical loading, these scaffolds serve as a model to study osteogenesis. To simulate physiological conditions, the bioreactor must apply 1000 compression cycles at forces up to 200 N, three times daily over 14 days. Upon implementation, validation testing and experimental studies exposed several limitations in the bioreactor’s control code. The system was initially programmed …

Evervital Patch: The Design And Development Of A Continuous Cardiac Monitoring Device For Post-Operative, In-Hospital Patients, Abigail Moeller, Jonathan Seid

Honors Theses

In the United States, due to the increasing prevalence of cardiovascular disease, over 900,000 cardiac surgeries are performed annually, with projections exceeding 1.3 million by 2029. Many post-surgical patients require continuous in-hospital cardiac monitoring, which is typically conducted using electrocardiograms (EKGs). However, traditional EKG systems such as bedside cardiac monitors and cardiac telemetry monitors rely on wired leads that can easily tangle, degrade signal quality, and require frequent readjustments or replacements due to wire breakage, and for the patient, this can cause discomfort from prolonged use. To overcome these challenges, our company, CardioSync, aims to develop a wireless cardiac monitoring …

Speed Of Shear Waves As A Function Of Frequency In Micellar Fluid, Michael Basha

Honors Theses

"Does My Student Need Aac?": Identifying The Factors Influencing Speech-Language Pathologists' Initiation Of Aac Evaluations Through Survey, Charisse Lapuebla

Honors Theses

Augmentative and alternative communication (AAC) methods and devices enable individuals to communicate when otherwise unable to communicate fluently and verbally. Introducing AAC to children with developmental disabilities encourages increased communication and speech production (Yuan et al., 2024). ASHA states that there are no prerequisites for AAC use. The authors wholeheartedly agree with this position (American Speech-Language-Hearing Association, n.d.). However, if no exclusion criteria for AAC use exists, AAC should be considered for each and every student. This is not common practice in the field. Due to the absence of exclusion criteria, the factors that prompt speech-language pathologists to initiate an …

Antioxidant Activity Of Pamam Dendrimer Stabilized Ascorbic Acid, Gabriella Srikureja

Honors Theses

Ascorbic acid (vitamin C) is an essential micronutrient for human health. It acts as an enzymatic cofactor in anabolic biochemical pathways such as the synthesis of collagen, dopamine, and norepinephrine.
