Northeast Parallel Architecture Center

We elaborate the SNAP---Scalable (ATM) Network and (PC) Platforms---view of computing in the year 2000. The World Wide Web will continue its rapid evolution, and in the future, applications will not be written for Windows NT/95 or UNIX, but rather for WebWindows with interfaces defined by the standards of Web servers and clients. This universal environment will support WebTop productivity tools, such as WebWord, WebLotus123, and WebNotes built in modular dynamic fashion, and undermining the business model for large software companies. We define a layered WebWindows software architecture in which applications are built on top of multi-use services. We discuss …

Task Iii Report: Water Use Estimation And Forecasting For The Kentucky River Basin, Glenn C. Blomquist, William Hoyt, D. Hu, C. Scott

KWRRI Research Reports

We estimate aggregate monthly water use for summer, peak demand and nonsummer off-peak demand periods for the Kentucky River Basin. Using Kentucky Division of Water use data, U.S. Census data for county demographic and economic conditions, and U.S. Weather Service data for weather conditions we estimate use for the 1970-1993 period. Our model allows for idiosyncratic effects of each of the 27 counties in the sample. We find factors such as population and manufacturing employment affect use and temperature and rainfall in current and preceding months effect use during the summer, peak period. The model predicts well within the sample …

A Guide For Extending Nature Lessons At The Yakima Arboretum, Marilou Cori Kinder

All Graduate Projects

The importance of providing a hands on natural environment curriculum was examined. Sources from 1938-1996 were found supporting the importance of such a curriculum. A search was conducted on the availability of a natural habitat curriculum that used a local resource. The search discovered the Yakima Arboretum had seven areas of interest along with a packet of brief lesson suggestions. These lessons were extended to include classroom activities that would provide students with background knowledge prior to a field trip to the Arboretum.

Origin Of Bermuda's Clay-Rich Quaternary Paleosols And Their Paleoclimatic Significance, Stanley R. Herwitz, Daniel R. Muhs, Joseph M. Prospero, Shannon Mahan, Bruce Vaughn

United States Geological Survey: Staff Publications

Saharan dust deposition on Bermuda during successive Quaternary glacial periods is consistent with patterns of general circulation models, which indicate that during glacial maxima the northeast summer trade winds were stronger than at present and reached latitudes higher than 30°N despite lower-than-present sea surface temperatures in the North Atlantic.

Cambrian Hydrocarbon Potential Indicated In Kentucky's Rome Trough, David C. Harris, James A. Drahovzal

Information Circular--KGS

A recent gas discovery in the Rome Trough has resulted in a new phase of deep exploration in eastern Kentucky. This activity is located in Elliott County, near the northern boundary fault of the Cambrian Rome Trough graben. The Carson Associates No. 1 Kazee well was drilled in 1994, and blew out with a reported uncontrolled flow of 11 million cubic feet of gas per day. Although completed at a much lower rate, this well renewed interest in the deep gas potential of the Rome Trough, which has seen sporadic drilling activity since the 1940's. Gas production in the Rome …

Scale Issues In Soil Moisture Modelling: Problems And Prospects, Rezaul Mahmood

School of Natural Resources: Faculty Publications

Soil moisture storage is an important component of the hydrological cycle and plays a key role in land-surface-atmosphere interaction. The soil-moisture storage equation in this study considers precipitation as an input and soil moisture as a residual term for runoff and evapotranspiration. A number of models have been developed to estimate soil moisture storage and the components of the soil-moisture storage equation. A detailed discussion of the implication of the scale of application of these models reports that it is not possible to extrapolate processes and their estimates from the small to the large scale. It is also noted that …

Captive Environmental Influences On Behavior In Zoo Drills And Mandrills (Mandrillus), A Threatened Genus Of Primate, Erik Terdal

Dissertations and Theses

Drills (Mandrillus leucophaeus) are an endangered species of African monkey (Cercopithecidae), and their sole congener the mandrill (Mandrillus sphinx) is vulnerable to extinction. Both species are threatened in the wild by deforestation and hunting.

Drills have a poor record of captive reproduction. Many individuals appear to have behavioral deficiencies which interfere with reproduction. Thus, the zoo population of drills does not serve as a “hedge” against the species’ total extinction: drills are endangered in captivity as well as in the wild. Mandrills, by contrast, reproduce well in captivity. Information on the behavior of mandrills in captivity may help zoo managers …

Leaner Environmental Policies For Agriculture, David E. Ervin, Elisabeth A. Graffy

Economics Faculty Publications and Presentations

Farmers and ranchers face a most troubling dilemma. Complex political forces have mapped two quite different paths to environmental management-a rollback of federal regulations or a buildup of traditional subsidies. In the words of a famous modern philosopher, "When you reach a fork in the road, take it!" But either choice poses risk for the industry and will not likely ameliorate nettlesome environmental problems. A third path could help the industry maintain competitiveness and meet environmental challenges. This path uses me latest science to identify agroenvironmental problems and emphasizes economically attractive technology to sustain environmental improvements.

Gypsum Karst Of The Baltic Republics, Bernardas Paukstys, Vytautas Narbutas

International Journal of Speleology

The Baltic Republics of Estonia, Latvia and Lithuania have karst areas developed in both carbonate and gypsiferous rocks. In the north, within the Republic of Estonia, Ordovician and Silurian limestones and dolomites crop out, or are covered by glacial Quaternary sediments. To the south, in Latvia and Lithuania, gypsum karst is actively developing in evaporites of Late Devonian (Frasnian) age. Although gypsum and mixed sulphate-carbonate karst only occupy small areas in the Baltic countries, they have important engineering and geo-ecological consequences. Due to the rapid dissolution of gypsum, the evolution of gypsum karst causes not only geological hazards such as …

Using Digital Elevation Models To Measure The Surface And Volumetric Change Of Athabasca Glacier, Alberta, Canada, 1919-1979, James Robb Reynolds

Theses and Dissertations (Comprehensive)

The Athabasca Glacier (52˚12'N, 117˚14'W) located at the Alberta-British Columbia border was studied to quantify its volumetric, area and elevation changes below 2400 m between 1919 and 1979. The data sources consist of maps produced using aerial and terrestrial photogrammetry in the years between 1919 and 1979. The maps were digitized and converted into raster digital elevation models (DEMs), the manipulation of which allowed values of surface and volumetric change to be calculated. These DEMs showed that between 1919 and 1979 the glacier lost 2.344 x 108m3 of volume and receded more than 1 km. Each of the source maps …

Mechanical And Chemical Weathering Of Periglacial And Non-Periglacial Forms On The Eastern Fosheim Peninsula, Ellesmere Island (Northwest Territories), Cameron Lawrence Chadwick

Theses and Dissertations (Comprehensive)

The purpose of this study is to examine the differences in the mechanical and chemical weathering of different periglacial and non-periglacial forms on the eastern Fosheim Peninsula. Forms studied include: solifluction lobes, non-sorted stripes, polygons, mudboils, wetted sloped, dry ridge and wet meadow. Most sites including the periglacial forms of solifluction lobes, non-sorted stripes, and polygons show signs of chemical and mechanical weathering. The weathering found at all sites was minute but may be significant given the slow rates of weathering in this environment. The individual environmental variables of moisture and temperature levels do not appear to have a direct …

Managing External Threats To National Parks In Canada's Western Mountains (Alberta), George Yap

Theses and Dissertations (Comprehensive)

External threats to protected areas exist because the area encompassed by the legal boundaries of many protected areas is less than what is needed to maintain a minimum viable population of various animal species and some types of plant associations. While external stresses to parks are the result of a wide range of human activities, they threaten ecological integrity in two general ways: by contributing to habitat fragmentation, alienation and loss (HFAL), and/or undermining the long-term viability of transboundary animal populations. However, in comparison to internal threats, addressing external threats is considerably more complex since park managers have no legal …

Relative Rates Of Sand Transport Through An Incipient Parabolic Dune At Pinery Provincial Park, Ontario (Ammophila Breviligulata, Calamovilfa Longifolia, Cakile Edentula, Juniperus Virginiana, Populus Deltoides), Sheri A. Longboat

Theses and Dissertations (Comprehensive)

Factors controlling the development, migration, and stability of an incipient parabolic dune in Pinery Provincial Park, Ontario were investigated in terms of grain size characteristics, rates of sediment transport, and local and regional winds. The parabolic dune, situated approximately 60 meters inland of Lake Huron, is dominated by sparsely scattered dune grass species of marram grass (Ammophila breviligulata), sand reed (Calamovilfa longifolia), and sea rocket (Cakile edentula). Small tree species of red cedar (Juniperus virginiana) and eastern cottonwood (Populus deltoides) emerge and increase in number beyond the parabolic dune. Mean grain sizes along a profile were coarsest on the beach …

Energy And Deforestation In Ghana: A Study Of Woodfuel-Deforestation Links In Rural Ghana, Iddrisu Adam

Theses and Dissertations (Comprehensive)

Forests are one of the most valuable natural resources of many countries, including Ghana. Timber and other forest products have contributed immensely to the development of the country. These same forests have been a source of sustenance to the Ghanian people. Most particularly, forests have been the principal source of domestic energy by way of providing woodfuels. The heavy reliance on forest resources is taking its toll on the health of Ghanaian forests. In recent years, there has been increased awareness of the depletion of trees—a problem that many researchers have attributed to the over-exploitation of forests especially for domestic …

Geomorphological Aspects Of Gypsum Karst Areas With Special Emphasis On Exposed Karst, Ugo Sauro

Medium- to large-size forms in gypsum karst are described, including dolines, blind valleys, ploje-like depressions, collapses and positive and/or residual forms such as outliers, cone-like hills, dome-like hills, mesa-like tabular blocks and plateaux and breccia pipe hills. The similarities and/or difference between gypsum and carbonate forms are discussed.

The Gypsum Karst Of Italy, Paolo Forti, Ugo Sauro

International Journal of Speleology

Gypsum karst has been studied in Italy since the last decades of the l9th Century. In 1917 the geographer Olinto Marinelli published “Fenomeni carsici delle regioni gessose d’Italia”, a fundamental synthesis of the early research. He distinguished 56 different morpho-karstic gypsum units and/or areas, which are all different in size and character, and described them, paying special attention to their surface morphology and hydrology. Marinelli listed all the main gypsum units and only a few secondary outcrops were overlooked. After Marinelli’s synthesis, except for some discussion of archaeological caves, only a few papers about gypsum karst and environment were published …
