Understanding Of Aerosol Transmission Of Covid 19 In Indoor Environments, Adama Barro, Cathal O'Toole, Jacob S. Lopez, Matthew Quinones, Sherene Moore

Publications and Research

Our reason for discussing severe acute respiratory syndrome corona virus 2 (SARS-CoV-2) or 2019 novel corona virus (Covid-19), is to understand its aerosol transmission characteristics in indoor spaces and to mitigate further spread of this disease by designing a new HVAC system. The problem that we are tackling is the spread of covid-19 droplets through aerosol transmission by looking at potential engineering solutions to the existing HVAC systems. The purpose is to eradicate the spread of the COVID-19 by testing indoor spaces in an effort to understand the effectiveness of ventilation controls. We believe that scientists and engineers have not …

A Guide To Freshwater Aquariums, Noah Savastano

Senior Honors Projects

The objective of this project was to create a complete guide, useful for someone of any aquarium expertise level, describing how to set up and care for an aquarium. This guide explains the science behind processes involved in setting up and maintaining an aquarium. It also educates the reader on how to properly prioritize the safety of the fish. A full text was first created including all relevant information gathered from scholarly texts and online sources. Original photographs were incorporated as a supplement to the text. Fish and aquatic plants were drawn to further illustrate the concepts that were described …

Two And Three-Dimensional Radiographic Imaging Of Contrast Agents In Heterogeneous Live Cell Media To Understand Contrast-Induced Toxicity, Fahaneda Hassan, Aldona Gjoni, Subhendra Sarkar

Publications and Research

Radiographic imaging was done using low and high energy radiography equipment. The test hypothesis that macromolecular aggregation changes sample noise in imaging samples for optical imaging methods. Inorganic complexes scatter radiation at the molecular level and may increase the sample noise locally. At high and low photon energies in various x-ray machines, sample and background noise were gathered and compared with those from mammography systems from mammography researchers. The samples with high macromolecular aggregates were prepared using various animal cell compositions and imaged under different conditions that produced different macromolecular dynamics within the samples and thus different image-based sample noise. …

Variations In Slow-Wave Eeg And Working Memory Deficits During Letter Number Sequencing Task Post-Concussion, Morgan Sotoloff

Neuroscience Presentations

Concussions are associated with various types of consequences, both short-term and long-term: ranging from acute symptomatology, resting protocols, return-to-play decisions, and the lingering effects that have been found to have significant impacts on cognitive processes and function in many individuals several months post-concussion. Previous research has demonstrated that certain dimensions of executive function are especially susceptible to mild traumatic brain injury (mTBI), specifically working memory and attention. Studies that have previously utilized electroencephalography (EEG), have found that increased very low frequency oscillations (VLFO) are associated with a disruption of goal-oriented activities, difficulties in cognition, hyperactivity, and inattention in concussed individuals …

Presence Of Electron Donor/Acceptor Radiographic Contrast Media In Unusual Photosynthesis Environment Of Fresh Plant Cells: Near-Infrared And X-Ray Characterization, Tetiana Soloviova, Subhendra Sarkar, Amina Shahbaz, Aldona Gjoni

Publications and Research

Photosynthesis is a chemical process through which light energy is used to convert inorganic material (water and carbon dioxide) into organic molecules. Anaerobic photosynthesis, also known as anoxygenic photosynthesis, is the process by which certain bacteria use light energy to create organic compounds but do not adequately involve oxygen. In this experiment we are trying to influence photosynthesis (light and dark reactions: PS-I and PS-II by electron rich gadolinium/iodine complexes like Eovist and Isovue. We also performed X-ray and NIR reflection spectroscopy (NIRS) to measure Gd difusivity and PS-I/II infrared response. The results for X-ray (45kvp and 5 Mas ) …

Year Long Water Quality Analysis Of White Horn Brook, Kevin Dyer

Senior Honors Projects

KEVIN DYER (Marine Biology)

Year-long Analysis of the Water Quality of White Horn Brook

Sponsor: Thomas Boving (Geological Sciences)

Water is the foundation for all life on earth and is the most vital resource on this planet. Despite this, oceans and waterways all over the world are being polluted and exploited in ways detrimental to their fundamental hydrologic functions. For instance, excess nitrate levels can lead to eutrophication which gives rise to harmful algae blooms. Low pH can cause the breakdown of CaCO3 exoskeletons of organisms, such mollusks. High temperature variations are major stressors to living things and can cause …

Fighting Waste And Feeding People: Exploring The Context Of Campus Food Waste And Student Recovery Efforts, Sarah Becker, Max Stout, Maddie Kuklentz, Savona Cerra

Environment and Sustainability Presentations

Wismer on Wheels is dedicated to our mission of not only reducing food waste on campus, but also reducing food insecurity in our wider community. The work of our team of over 35 student volunteers reflects that dedication. This past year we became the official Food Recovery Network chapter for Ursinus, broadened outreach efforts on- and off-campus, and boosted food waste education, all while recovering unprecedented quantities of food. In this presentation, we celebrate the accomplishments of our dedicated volunteers while exploring deeper questions about food waste on the Ursinus campus. Why are we seeing such massive food recovery numbers …

Progress Presentation On The Proposed Function Of Protein 4diu Through Bioinformatics Analyses, Melissa Hoff

Biochemistry and Molecular Biology Presentations

The BASIL project is a scientific inquiry project that aims to determine the function of a protein from its structure. Biochemistry students completed wet lab work, while structural biology students worked in silico. The purpose of this study was to determine the function of the protein with PDB ID: 4DIU. Bioinformatics analyses were completed using several databases: BLAST, Dali, Pfam, and Moltimate, and imaging of the protein was completed using PyMOL software. The BLAST database aligned the primary sequence with known protein sequences. The Dali database compared protein structure with known structures through global alignment. The Pfam database matched our …

The Classification Of An Unknown Protein 3h04, Britney Dyszel

Biochemistry and Molecular Biology Presentations

An unclassified protein in the Protein Data Bank, 3H04, was selected as a protein of interest. Research was performed in silico to gain key information on the structure, sequence, and homology of protein 3H04. This research was guided using the BASIL Project’s protocols on in silico research. Several databases were utilized to study protein 3H04. Based on the data gathered, unclassified protein 3H04 is an aminopeptidase that cleaves prolyl-dipeptidyl peptide bonds through alpha beta hydrolase function.

Constructing A Series Of Informative Videos And Building Social Media Platforms For Save One Soul Animal Rescue League, Cassandra Munroe

Senior Honors Projects

Approximately six million animals enter shelters each year. Of those six million animals, about two million are killed each year. Due to the lack of spaying and neutering and overcrowding, especially in the southern states of the U.S., the population of animals in high-kill shelters is alarming. Save One Soul Animal Rescue League (SOSARL) is a volunteer-driven non-profit dog rescue founded and based in Rhode Island. The mission of SOSARL is to permanently rehome homeless, neglected, abandoned, and at-risk dogs. The majority of the dogs rehomed by SOSARL are transported from overcrowded high-kill shelters in the Southern U.S. or from …

From Soap Bubbles To Cell Membranes, Peter Beltramo

Science and Engineering Saturday Seminars

Have you ever blown a soap bubble and wondered - what causes the bubble to be so stable and produces those colorful reflections of light? The answer lies in a class of molecules known as surfactants, and they have remarkable similarities with the molecules that comprise the cell membrane of all living organisms. In this workshop, we will use the analogy of a soap bubble to describe cellular membrane properties such as chemistry, structure, membrane transport, and ion channel formation. The goals of this workshop are to 1) link initially intractable concepts in biology like intracellular transport to the intuitive …
