Collaborative Research: Matching Levels Of Detail In Descriptions And Depictions Of Geographic Space, Michael Warboys
University of Maine Office of Research Administration: Grant Reports
This collaborative research project focuses on issues related to wayfinding, and is at the interface of geographic information science and human cognition. The research addresses the questions of the relationship between verbal and pictorial representations of geographic information, and how both representation modes can be successfully integrated in systems relating geographic information to users. To address this question, a theory of content and level of geographic detail is constructed that is independent of specific mode. The research is founded upon computational and cognitive theories of geographic information. The main idea is that theories of information granularity can be imposed on …

Linking Bioturbation And Sensory Biology: Chemoreception Mechanisms In Deposit-Feeding Polychaetes, Sara M. Lindsay, Paul Rawson
Linking Bioturbation And Sensory Biology: Chemoreception Mechanisms In Deposit-Feeding Polychaetes, Sara M. Lindsay, Paul Rawson
University of Maine Office of Research Administration: Grant Reports
Soft-sediment benthic habitats are ubiquitous in the marine environment and typically feature macrofaunal assemblages that include large numbers of deposit-feeding invertebrates such as polychaetes, bivalves, gastropods, crustaceans, holothurians, and hemichordates. Via their feeding, modulated in part by chemoreception, these organisms have profound effects on the ecology, biology, geology, and chemistry of their habitats. Very little is known, however, concerning the physiology and molecular biology of chemoreception in deposit feeders.
This research is a comprehensive investigation of the sensory mechanisms coordinating chemoreception in deposit feeding spionid polychaetes. It directly addresses this lack of information and will therefore have a significant impact …

Bioaccumulation of trace metals in plant tissues can present a health risk to wildlife, and potentially to humans. The Passamaquoddy Tribe in Maine was concerned about health risks of cadmium (Cd) because of a health advisory for moose liver and kidney consumption due to high Cd levels. In addition to Cd, this study evaluated concentrations of aluminum (Al), calcium (Ca), copper (Cu), iron (Fe), potassium (K), magnesium (Mg), manganese (Mn), nickel (Ni), phosphorus (P), lead (Pb), and zinc (Zn) in four common terrestrial moose-browse species, associated forest soils, and two species of aquatic vegetation on Passamaquoddy tribal land in eastern …

Earth Science Faculty Scholarship
We have determined the flux of calcium, chloride and nitrate to the McMurdo Dry Valleys region by analysing snow pits for their chemical composition and their snow accumulation using multiple records spanning up to 48 years. The fluxes demonstrate patterns related to elevation and proximity to the ocean. In general, there is a strong relationship between the nitrate flux and snow accumulation, indicating that precipitation rates may have a great influence over the nitrogen concentrations in the soils of the valleys. Aeolian dust transport plays an important role in the deposition of some elements (e.g. C(2+)) into the McMurdo Dry …

Earth Science Faculty Scholarship
Stable oxygen analyses and snow accumulation rates from snow pits sampled in the McMurdo Dry Valleys have been used to reconstruct variations in summer temperature and moisture availability over the last four decades. The temperature data show a common interannual variability, with strong regional warmings occurring especially in 1984/85, 1995/96 and 1990/91 and profound coolings during 1977/78, 1983/84, 1988/89, 1993/94, and 1996/97. Annual snow accumulation shows a larger variance between sites, but the early 1970s, 1984, 1997, and to a lesser degree 1990/91 are characterized overall by wetter conditions, while the early and late 1980s show low snow accumulation values. …

Final Report: Westbrook Downtown Parking Study/Management Plan, Gorrill-Palmer Consulting Engineers, Inc.
Maine Town Documents
In the early 2000's, Westbrook was the beneficiary of an upswing in the Southern Maine economy, aided by a strong marketing effort on the part of the City. As a result, new office buildings and retail facilities located in or near the downtown area and older buildings were rehabilitated and redeveloped. This increase in commercial and business activity increased the demand for parking downtown. With an eye toward long-term growth, a parking management plan was developed to provide the tools necessary to manage the increased demand for parking.
Diel And Tidal Rhythms Of Emercenge Events Based On Acousitc Observations In A Shallow Estuary, Mei Sato
Diel And Tidal Rhythms Of Emercenge Events Based On Acousitc Observations In A Shallow Estuary, Mei Sato
Electronic Theses and Dissertations
Field observations of emergence events by epibenthic animals were conducted with two Tracor Acoustic Profiling Systems (TAPS) in the Damariscotta River estuary, Maine, in fall 2005 and summer 2006. Spectral analysis revealed that periodic temporal variability of the acoustic signals was concentrated at four periods. One was the solar day (24 h) and the other three were lunar tidal periods of 25.82 (diurnal or Oi), 12.42 (semidiurnal or M2) and 6.21 h (half the semidiurnal period). The mysid Neomysis americana showed strong nocturnal migration patterns of water-column activity during its peak summer emergence season, regulated by the diel cycle. Toward …
Surface Modification Of Pigments And Its Role In Offset Ink Setting, Wei Gu
Surface Modification Of Pigments And Its Role In Offset Ink Setting, Wei Gu
Electronic Theses and Dissertations
Ink setting affects offset print quality issues such as print mottle and print gloss. It is known that ink setting depends on many factors, such as the nature of the substrate, the properties of the coating, and the ink formulation. However, the role of pigment surface chemistry in offset ink setting is unknown. From an experimental perspective, it is difficult to determine the role of the surface chemistry as it requires paper coatings that are similar in physical properties and differ only in the pigment surface chemistry. The aim of this study was two-fold. The first was to apply methods …
Derivation Of Change From Sequences Of Snapshots, Dominik Wilmsen
Derivation Of Change From Sequences Of Snapshots, Dominik Wilmsen
Electronic Theses and Dissertations
Current research in the domain of geographic information science considers possibilities of including another dimension, time, which is generally missing to this point. Users interested in changes have few functions available to compare datasets of spatial configurations at different points in time. Such a comparison of spatial configurations requires large amounts of manual labor. An automatic derivation of changes would decrease amounts of manual labor. The thesis introduces a set of methods that allows for an automatic derivation of changes. These methods analyze identity and topological states of objects in snapshots and derive types of change for the specific configuration …
Engineering Calpastatin To Develop A Sensor To Detect Active Calpain, Lisa M. Vanhooser
Engineering Calpastatin To Develop A Sensor To Detect Active Calpain, Lisa M. Vanhooser
Electronic Theses and Dissertations
Calpains, Ca2+-activated cysteine proteases are essential for early embryonic development and function in signal transduction, cell adhesion, and apoptosis. Calpains also contribute to cataractogenesis, myocardial infarctions, and neurodegenerative diseases such as Alzheimer's. The various methods currently available to demonstrate these roles do not directly identify spatial or temporal activation of calpain in cells. Therefore, a tool to detect active calpain in situ will be useful. Calpastatin is the ubiquitous, endogenous inhibitor that specifically binds the active conformation of the conventional calpains. Calpastatin consists of four homologous domains each containing three subdomains A, B, and C. The crystal structure …

Yellow Tree: A Distributed Main-Memory Spatial Index Structure For Moving Objects, Hariharan Gowrisankar
Electronic Theses and Dissertations
Mobile devices equipped with wireless technologies to communicate and positioning systems to locate objects of interest are common place today, providing the impetus to develop location-aware applications. At the heart of location-aware applications are moving objects or objects that continuously change location over time, such as cars in transportation networks or pedestrians or postal packages. Location-aware applications tend to support the tracking of very large numbers of such moving objects as well as many users that are interested in finding out about the locations of other moving objects. Such location-aware applications rely on support from database management systems to model, …
Determining Environmental Drivers Of Fish Community Structure Along The Coast Of Maine, Adrian Jordaan
Determining Environmental Drivers Of Fish Community Structure Along The Coast Of Maine, Adrian Jordaan
Electronic Theses and Dissertations
The work presented here was conceived to determine whether structure in marine communities could be related to multiple scaled environmental parameters, as seen in lake and stream systems. Four datasets collected from 2001 to 2005 were used. The datasets ranged from local scale tidepool and estuarine surveys, to more regional intertidal/subtidal surveys and conclude using a coast-wide trawl survey. Initially, a bootstrap program for running principal component analysis (PCA) was developed and tested for utility with additional information from Pearson correlation coefficients. The bootstrap-PC A program was capable of determining confidence limits for correlations amongst species. The results from analysis …

Satellite Remote Sensing Of Glaciers And Ice Caps In Svalbard, Eurasian High Arctic, Gordon S. Hamilton
Satellite Remote Sensing Of Glaciers And Ice Caps In Svalbard, Eurasian High Arctic, Gordon S. Hamilton
University of Maine Office of Research Administration: Grant Reports
Recent compilations of climate-related observations show that important changes are now underway in the High Arctic, probably as a response to anthropogenic greenhouse gas emissions over the last approximately 250 years. These changes include warming of the troposphere, reductions in sea ice cover, decreases in snow cover area, warming of tundra permafrost, and negative mass balances of glaciers and ice caps. In many instances, observations of change are relatively short in duration or sparse in spatial extent. The Principal Investigators will study glacier and ice cap variations over the approximately last 80 years and at a large scale on Svalbard. …
