Predictive Model Of Ocean Sediment Binding, Erica Delaney
Predictive Model Of Ocean Sediment Binding, Erica Delaney
Honors Theses
This project explored the relationship between sediment size, sediment composition and the concentration of mercury. The samples were taken from Narragansett Bay in Rhode Island. Knowledge and understanding of the binding ability of heavy metals, specifically mercury, will help to improve remediation efforts in the future. Analysis of elemental composition was conducted using the Elementar Analyzer and much troubleshooting of the instrument was necessary. End result of the project was the ability to work successfully with an advisor, as well as the ability to troubleshoot, operate and maintain the instrument.

Discrimination And Aggregative Patterns Among And Between Populations Of Entamoeba Spp., Katelyn M. Higgins
Honors Theses
Kin recognition facilitates the evolution of cooperation in animals, but its relevance in microorganisms and their behavior toward relatives remains unclear. The Entamoeba lineage constitutes an ideal model to determine the behavioral and signaling cues needed for aggregative preference. Chemical cues have been reported for E. histolytica but not E. dispar, suggesting cell-communication between con-specifics and behavioral differences with relevance for disease. Entamoeba varieties have been reported as ‘morphologically undistinguishable’. Two strains of E. invadens have been isolated from different hosts (VK-1: NS - Varanus komodoensis and IP1- serpentes) but were classified within the same ‘species’. Trophozoites …
Characterization Of Expression Of The Kcne Gene Family In Zebrafish, Danio Rerio, Lauren Vernlund
Characterization Of Expression Of The Kcne Gene Family In Zebrafish, Danio Rerio, Lauren Vernlund
Honors Theses
The KCNE gene family codes for five transmembrane accessory proteins, "minK related peptides" or Mirps, involved in the modification of voltage-gated potassium (Kv) channels, K+ selective pores vital in the regulation of membrane potential and repolarization in all organisms. In mammals, all five KCNE gene members are conserved and active in the heart. In the zebrafish Danio rerio, there are no apparent orthologs for KCNE2 or KCNE5, yet they contain Kv channels with homologous structure, function, and Mirp regulatory behavior to other organisms. Sequence analysis of wildtype zebrafish KCNE1, 3 and 4, and rtPCR on RNA from zebrafish tissues …
