Project Oasis: Optimizing Aquaponic Systems To Improve Sustainability, Siddharth Nigam, Paige Balcom
Project Oasis: Optimizing Aquaponic Systems To Improve Sustainability, Siddharth Nigam, Paige Balcom
Honors Theses and Capstones
Started in Fall 2015, Project OASIS (Optimizing Aquaponic Systems to Improve Sustainability) is an interdisciplinary capstone project with the goal of designing a sustainable and affordable small-scale aquaponic system for use in developing nations to tackle the problems of malnutrition and food insecurity. Aquaponics is a symbiotic relationship between fish and vegetables growing together in a recirculating system. The project’s goals were to minimize energy consumption and construction costs while using universally available materials. The computational fluid dynamics (CFD) software OpenFOAM was used to create transient and steady-state models of fish tanks to visualize velocity profiles, streamlines, and particle movement. …
Isolation And Identification Of Bacterial Endosymbionts In The Brooding Brittle Star Amphipholis Squamata, Abbey Rose Tedford
Isolation And Identification Of Bacterial Endosymbionts In The Brooding Brittle Star Amphipholis Squamata, Abbey Rose Tedford
Honors Theses and Capstones
Symbiotic associations with subcuticular bacteria (SCB) have been identified and studied in numerous echinoderms, including the SCB of the brooding brittle star, Amphipholis squamata. These SCB, however, have not been studied using current next generation sequencing technologies. Previous studies on the SCB of A. squamata placed these bacteria in the genus Vibrio (γ-Proteobacteria), but subsequent studies suggested that the SCB are primarily composed of α-Proteobacteria. The present study examines the taxonomic composition of SCB associated with A. squamata from the Northwest Atlantic. DNA was extracted using a CTAB protocol and 16S rRNA sequences were amplified …
Sea Turtle Response To Climate Change: Analyzing Current And Predicting Future Impacts On Populations, Habitat, And Prey Populations, Eva J. Golden
Sea Turtle Response To Climate Change: Analyzing Current And Predicting Future Impacts On Populations, Habitat, And Prey Populations, Eva J. Golden
Honors Theses and Capstones
With the prediction of devastating global climate change effects for the near future, scientists are expanding their research and understanding of some of the most severely affected organisms. Because sea turtles rely on both marine and terrestrial habitats for survival, and because coastal areas are already experiencing great losses due to sea level rising, human development, and pollution, all seven species are already listed as threatened under the Endangered Species Act. In this literature analysis, I examined the many factors that contribute to a sampling of the current sea turtle population status as well as scrutinized turtle adaptability to the …
Food System Education Among High School Students, Yussra Mt Ebrahim
Food System Education Among High School Students, Yussra Mt Ebrahim
Honors Theses and Capstones
As the American public school system is currently designed, the average student is likely to graduate high school without ever having received any formal instruction regarding the food system in which he or she takes part as a consumer. Such instruction was not necessary up until the current era of separation between consumers and food production. Through this research project, I sought to demonstrate the effectiveness of a single introductory lesson on the issues confronting the modern American food system, which I taught to two high school biology classrooms. A pre-survey was taken by the high school biology students online …
Attached Algae As An Indicator Of Water Quality: A Study Of The Viability Of Genomic Taxonomic Methods, Allison R. Wood
Attached Algae As An Indicator Of Water Quality: A Study Of The Viability Of Genomic Taxonomic Methods, Allison R. Wood
Honors Theses and Capstones
This research involved evaluating algae as an indicator of water quality in New Hampshire's rivers, with a focus on the Great Bay Estuary. The project had three main goals. First, determining whether or not algae would work as an indicator of water quality in the great bay ecosystem, an environment where tidal currents are strong and water composition is mixed. The second goal was to compare traditional microscopic methods of taxonomy with emerging genomic methods, increasing the economic viability of attached algae monitoring. The third project goal, still underway, is to evaluate massive amounts of genomic data from the Great …
Effect Of Direct-Fed Microbials And Enzyme Supplementation In Prepartum Holstein Cows On Colostrum And Calf Immunity, Erin M. Shangraw
Effect Of Direct-Fed Microbials And Enzyme Supplementation In Prepartum Holstein Cows On Colostrum And Calf Immunity, Erin M. Shangraw
Honors Theses and Capstones
In cows, colostrum is composed of several antibodies and nutrients to provide immunity and energy to the calf. Feeding calves high quality colostrum has been shown to improve calf health, leading to reduced mortality in calves and greater milk production in cows. The addition of direct-fed microbials (DFM) to cow diets has been theorized to improve feed efficiency and milk production, with studies showing mixed results. However, few experiments have studied the effect of feeding DFM on colostrum quality. In this experiment two treatments were given, 1) DFM and 2) DFM and enzymes (DFME). Colostrum was …
Implementing Pasteurized Donor Human Milk Programs In Level One And Two Nurseries: Policies, Barriers, And Successes, Rebecca Phipps Smeltzer
Implementing Pasteurized Donor Human Milk Programs In Level One And Two Nurseries: Policies, Barriers, And Successes, Rebecca Phipps Smeltzer
Honors Theses and Capstones
Pasteurized donor human milk (PDHM) as feeding supplementation has been shown to prevent and lower rates of gastrointestinal infection and increase exclusive human milk consumption (EHM) in critically-ill, low birthweight and premature infants. Policies/ procedures for the use of PDHM in “well” newborns and low birth weight newborns with non-life-threatening illness, level I and II nurseries, respectively, have not been established. The objective of this research is to gather and summarize policies/procedures and experiences from four hospitals in the northeast US that use PDHM in level I/II nurseries. Data was collected from interviews with hospital administrators and each hospital’s PDHM …
Contrast Response Functions Of On- And Off-Cells In Motion-Induced Blindness, Megan E. Lusignan
Contrast Response Functions Of On- And Off-Cells In Motion-Induced Blindness, Megan E. Lusignan
Honors Theses and Capstones
Motion-Induced Blindness (MIB) is the perceived, spontaneous disappearance of a salient target when it is viewed in the presence of a moving mask, and is believed to be controlled by extrastriate area 5 (Donner et al., 2008). The ON and OFF pathways in the human visual system are responsible for the detection of increments and decrements of light, respectively. The OFF pathway is more sensitive to decrements than the ON pathway is to increments before the middle layers of V1. However, after this point, the sensitivities are comparable in strength. Past experiments in this lab have shown that the ON …
