Improving Campus Safety and Sustainability by Bringing Renewable Energy Technology to the American Farm School

Limited street lighting on the American Farm School campus in Thessaloniki, Greece presents safety hazards to pedestrians and motorists on campus roads. Through interviews, direct observation, and textual research, we identified the areas that most need increased lighting, and developed systems and funding strategies to meet these needs. To provide adequate lighting while limiting light pollution and maintaining the natural aesthetic of campus, we recommend low temperature covered LED lamps powered by roof-mounted solar panels to mitigate the long-term electricity expenses

Wildlife Crossing Development for Highway 1 in Batipa, Panama

This project utilized data collection and structural analysis methods to design a wildlife crossing appropriate to the environmental specifications of Highway 1 on the Batipa Peninsula, Panama. Once constructed, the bridge will encourage permeable population flow between previously divided habitats, thus promoting healthy ecosystems. A complete design in both AutoCAD and AutoDesk Revit was provided to Universidad Tecnológica Oteima to pitch the project to potential sponsors for funding and to the Panamanian government for permission to move forward with construction

Isotope ratios of H, C, and O in CO2 and H2O of the Martian atmosphere

Stable isotope ratios of H, C, and O are powerful indicators of a wide variety of planetary geophysical processes, and for Mars they reveal the record of loss of its atmosphere and subsequent interactions with its surface such as carbonate formation. We report in situ measurements of the isotopic ratios of D/H and O-18/O-16 in water and C-13/C-12, O-18/O-16, O-17/O-16, and (CO)-C-13-O-18/(CO)-C-12-O-16 in carbon dioxide, made in the martian atmosphere at Gale Crater from the Curiosity rover using the Sample Analysis at Mars (SAM)'s tunable laser spectrometer (TLS). Comparison between our measurements in the modern atmosphere and those of martian meteorites such as ALH 84001 implies that the martian reservoirs of CO2 and H2O were largely established similar to 4 billion years ago, but that atmospheric loss or surface interaction may be still ongoing
