Environmental Monitoring Report For Volturnus Deployment In Castine, Me, Damian C. Brady, University Of Maine Advanced Structures And Composites Center

Maine Sea Grant Publications

On June 13th, 2013 the University of Maine’s VolturnUS 1:8 floating offshore wind turbine was energized and began delivering electricity through an undersea cable to the Central Maine Power electricity grid. Deployment continued until late November 2014. The following describes the results of extensive environmental monitoring at the Castine site. The primary observations of the site were derived from weekly visual surveys, bat echolocation detectors, underwater acoustic receivers, and web camera surveillance. The latter method consisted of observing the turbine and platform by web camera every 15-30 seconds throughout the deployment.

Collaborative Research: A Nanostructure Sensor For Measuring Dissolved Iron And Copper Concentrations In Coastal And Offshore Seawater, Mark Wells, Carl Tripp

University of Maine Office of Research Administration: Grant Reports

Iron and Copper serve as key co-constituents for numerous enzymes in a wide range of biological systems, and their elevated or impoverished levels in aqueous systems have dramatic consequences at organismal, ecosystem, and human health scales. Over the last decade these effects have increasingly been recognized to be important in ocean systems. Identifying sites and times where these metals cause negative environmental outcomes is greatly hampered by their comparatively sparse datasets. This problem is a direct consequence of the analytical challenge of obtaining accurate Fe and Cu determinations in saline waters at very low (trace) concentrations, and the limitations of …

Selective Hydrogenation Of Furfural To Furfuyl Alcohol Over Copper Magnesium Oxide, Andrew Estrup

Honors College

Furfural is a byproduct of biomass hydrolysis and novel means of utilizing this platform chemical are at the forefront of biofuel research. This project investigated many of the various and viable means of catalytic upgrading of furfural to other value-added chemicals, before ultimately exploring the conversion of furfural to furfuryl alcohol over a copper catalyst on a magnesium oxide support. Reasonable reaction conditions, mechanisms, and catalysts for the conversion of furfural to various products and platform chemicals exist, but no circumstance represents an obviously preferred method. The objective of this research project was to design and conduct experiments that characterize …

Physical Properties Of Iron Oxide Nanoparticles, Nicklaus Carter

Honors College

Magnetic Resonance Imaging (MRI) relies heavily on contrast agents such that diagnosis of various diseases can be made with increased confidence. Current contrast agents for MRI depend on various chelated molecules composed of a toxic gadolinium ion, Gd³⁺. In 2006, a discovery was made connecting Nephrogenic Systemic Fibrosis (NSF) and these gadolinium based contrast agents (GBCAs). The connection between life threatening NSF and GBCAs stems from patients with pre-existing kidney malfunctions. It has been proposed that an alternative agent such as iron oxide nanoparticles (IONPs) be investigated. These IONPs theoretically will have similar responses in efficiency of improving …

Bates Mill #5: A Case Study In Innovation, Past And Future, George Peterson

Honors College

Bates Mill #5 has stood as a symbol of innovation in downtown Lewiston Maine

since 1914 when it was completed. It has been vacant since the early 2000s when the remnants of the Bates Manufacturing Company moved their textile operation to Monmouth, Maine. The city of Lewiston seized Mill #5 in 1992 for unpaid taxes and has been grappling with how to reuse the property since then. In order to discuss the possible futures of Mill #5, it is important to have an understanding of the situation as it stands today; what has recently been done with the building and …

Nue: Nano Science And Laboratory Experience (Scale) At Umaine, Rosemary L. Smith, Scott D. Collins, Michael D. Mason

University of Maine Office of Research Administration: Grant Reports

This Nanotechnology Undergraduate Education (NUE) in Engineering program entitled, "NUE: Nano Science And Laboratory Experience (ScALE) at UMaine", at the University of Maine, under the direction of Dr. Rosemary L. Smith, aims to introduce the basic concepts, applications, and implications of nanoscale science and engineering to all first-year engineering students at the University of Maine (UMaine). The proposed approach is to add nanoscience and nanoscale engineering content to the required 'introduction to' engineering courses offered by each engineering department. This content will be designed, developed and delivered as a 'drop-in' module, in collaboration with the instructors for each department's course. …

Csr: Small: Collaborative Research: Sane: Semantic-Aware Namespace In Exascale File Systems, Yifeng Zhu

University of Maine Office of Research Administration: Grant Reports

Explosive growth in volume and complexity of data exacerbates the key challenge facing the management of massive data in a way that fundamentally improves the ease and efficacy of their usage. Exascale storage systems in general rely on hierarchically structured namespace that leads to severe performance bottlenecks and makes it hard to support real-time queries on multi-dimensional attributes. Thus, existing storage systems, characterized by the hierarchical directory tree structure, are not scalable in light of the explosive growth in both the volume and the complexity of data. As a result, directory-tree based hierarchical namespace has become restrictive, difficult to use, …
