Oczyszczanie Gazów Odlotowych Ze Spalania Odpadów Niebezpiecznych, Robert Oleniacz Dec 2000

Oczyszczanie Gazów Odlotowych Ze Spalania Odpadów Niebezpiecznych, Robert Oleniacz

Robert Oleniacz

Flue gas cleaning system is a very important part of each hazardous waste incineration plant. Air pollutant emission limit values permissible for this process in Member States of the European Union are so rigorous that the installation designers there are forced to use very effective and of course expensive solutions. In the paper a review of methods and systems used to the treatment of flue gases from hazardous waste incineration is presented. This can be particularly useful in the face of the adaptation of existing waste incineration plant operating in Poland with European Union requirements.

English title: Cleaning of flue …

The Savannah River Site: Site Description, Land Use And Management History, David L. White, Karen F. Gaines

Publications

The 78,000-ha Savannah River Site, which is located in the upper Coastal Plain of South Carolina along the Savannah River, was established as a nuclear production facility in 1951 by the Atomic Energy Commission. The site’s physical and vegetative characteristics, land use history, and the impacts of management and operations are described. Aboriginal and early European settlement was primarily along streams, where much of the farming and timber cutting have occurred. Woodland grazing occurred in the uplands and lowlands. Land use intensity increased after the Civil War and peaked in the 1920s. Impacts from production of cotton and corn, naval …


An Evaluation Of Stream Flow Characteristics And Fecal Coliform Loads In Sayler's Creek Watershed, South Central Virginia, David Straton Gilbert Dec 2000

An Evaluation Of Stream Flow Characteristics And Fecal Coliform Loads In Sayler's Creek Watershed, South Central Virginia, David Straton Gilbert

Theses & Honors Papers

The Sayler's Creek watershed is located within Prince Edward County, Nottoway, and Amelia Counties of the south central region of Virginia. The Sayler's Creek Watershed consists of two small creeks: Big Sayler's Creek and Little Sayler's Creek. The Environmental Protection Agency has Big Sayler's Creek listed as impaired and not Little Sayler's Creek. Based upon visual inspections of the Sayler's Creek watershed throughout the year, Little Sayler's Creek is inlpaired for fecal coliform instead of Big Sayler's Creek. Another hypothesis of this study is that fecal coliform levels are directly related to runoff from cattle ranches in the immediate floodplain …


Effects Of Temperature Anomalies On The Palmer Drought Severity Index In The Central United States, Q. Steven Hu, Garry D. Wilson Dec 2000

Effects Of Temperature Anomalies On The Palmer Drought Severity Index In The Central United States, Q. Steven Hu, Garry D. Wilson

School of Natural Resources: Faculty Publications

The purpose of this study is to improve our understanding of temperature and precipitation effects on the Palmer Drought Severity Index (PDSI). Both theoretical and observational analyses were applied to separate and compare temperature and precipitation effects on PDSI. The results showed that because of the dependence of PDSI on the ‘climatologically appropriate rainfall’, which is a function of time and varies with surface air temperature, the PDSI can be equally affected by temperature and precipitation, when both have similar magnitudes of anomalies. Calculations using observational data further illustrated the temperature influence on PDSI in different climate regions in the …

Ecological And Physiological Factors Affecting Nesting Success Of Burrowing Owls In Buffalo Gap National Grassland, Randall L. Griebel Dec 2000

Ecological And Physiological Factors Affecting Nesting Success Of Burrowing Owls In Buffalo Gap National Grassland, Randall L. Griebel

School of Natural Resources: Dissertations, Theses, and Student Research

The western burrowing owl (Athene cunicularia hypugea) has been declining throughout much of its range, and in some areas, quite dramatically. In the Great Plains region, these declines appear to be closely associated with declines in prairie dog numbers. Most research to date has taken place on relatively small, fragmented prairie dog colonies. The objectives of this study were to analyze burrowing owl reproductive performance (i.e., clutch size, brood size, and number fledged), and nestling body condition in relation to nest level and colony level factors in Buffalo Gap National Grassland, South Dakota. Buffalo Gap contains large prairie …

Preliminary Assessment Of Client Interest In And Needs Of The New England Environmental Finance Center, New England Environmental Finance Center, University Of Southern Maine

Planning

The New England Environmental Finance Center (NE/EFC) has been conceived as a knowledge-based clearinghouse, training, and change-agent program aimed at helping EPA's constituencies find financially successful approaches to environmental improvements. The NE/EFC will develop approaches to needs of particular priority in New England and potentially useful throughout the nation; share such approaches through the EFC national network; and help make tools from that network accessible throughout New England. In 1999 we began exploring with potential users how this ninth of the nation's EFCs might best address the region's needs. The assessment continued through the Muskie School's EFC proposal to EPA …


Utility Of North Atlantic Right Whale Museum Specimens For Assessing Changes In Genetic Diversity, Howard C. Rosenbaum, Mary G. Egan, Phillip Clapham, Robert L. Brownell Jr., Sobia Malik, Moira Brown, Bradley White, Peter Walsh, Rob Desalle Dec 2000

Utility Of North Atlantic Right Whale Museum Specimens For Assessing Changes In Genetic Diversity, Howard C. Rosenbaum, Mary G. Egan, Phillip Clapham, Robert L. Brownell Jr., Sobia Malik, Moira Brown, Bradley White, Peter Walsh, Rob Desalle

United States Department of Commerce: Staff Publications

We examined six historical specimens of the endangered North Atlantic right whale (Eubalaena glacialis) using DNA isolated from documented baleen plates from the late nineteenth and early twentieth centuries. Sequences from the mitochondrial DNA (mtDNA) control region from these samples were compared with those from a near-exhaustive survey (269 of approximately 320 individuals) of the remaining right whales in the western North Atlantic Ocean. Our results suggest that there has been only relatively modest change in maternal lineage diversity over the past century in the North Atlantic right whale population. Any significant reduction in genetic variation in the …

United States Department of Commerce: Staff Publications

Normile reports on Japan's expanded scientific whaling program and notes that "Canada, the United States, the Soviet Union, South Africa, and Japan were among several countries that [conducted scientific whaling] before 1982 [the year the IWC passed the worldwide commercial moratorium on whaling], but in recent years Japan has stood alone." Although true, this statement omits three equally important points.

Extended Water Quality Monitoring Of The Lincoln Lake Watershed, Paul F. Vendrell, K. F. Steele, M. A. Nelson, L. W. Cash, R. W. Ncnew

Technical Reports

For seven years, the Lincoln Lake (Moores Creek and Beatty Branch) watershed was monitored for improvements in water quality resulting from agricultural best management practices (BMP) implemented to reduce nutrient transport. During the first three years of monitoring (1991 to 1994), nitrogen transport declined significantly (Edwards et al., 1994, 1996, and 1997) under both base and storm flow conditions. This decline in nitrogen transport was again observed in the three-year period following 1994 (Vendrell et al. 1998). This monitoring effort has demonstrated that water quality bas improved in the Lincoln Lake watershed. However, since the nitrogen transport continued to decline …

The Effectiveness Of The Asos, Mmts, Gill, And Crs Air Temperature Radiation Shields*, K. G. Hubbard, X. Lin, E.A. Walter-Shea

School of Natural Resources: Faculty Publications

Periodic upgrades of air temperature measurement systems in surface weather station networks cause data discontinuities. From a climatological viewpoint, it is necessary to evaluate the air temperature data discontinuities when air temperature radiation shields are upgraded. This study was undertaken to investigate the effectiveness of four common air temperature radiation shields including the Automated Surface Observing System (ASOS), the Maximum–Minimum Temperature System (MMTS), the Gill, and the Cotton Region Shelter (CRS) shields. The solar radiation shielding effectiveness for each shield under typical grass ground surface and different artificial surfaces (black, white, and aluminum) were investigated. The shield effectiveness was evaluated …

Simulation Of Daily And Monthly Stream Discharge From Small Watersheds Using The Swat Model, Crystal A. Spruill, Stephen R. Workman, Joseph L. Taraba Nov 2000

Simulation Of Daily And Monthly Stream Discharge From Small Watersheds Using The Swat Model, Crystal A. Spruill, Stephen R. Workman, Joseph L. Taraba

Biosystems and Agricultural Engineering Faculty Publications

The Soil and Water Assessment Tool (SWAT) was evaluated and parameter sensitivities were determined while modeling daily streamflows in a small central Kentucky watershed over a two-year period. Streamflow data from 1996 were used to calibrate the model and streamflow data from 1995 were used for evaluation. The model adequately predicted the trends in daily streamflow during this period although Nash-Sutcliffe R2 values were –0.04 and 0.19 for 1995 and 1996, respectively. The model poorly predicted the timing of some peak flow values and recession rates during the last half of 1995. Excluding daily peak flow values from August …

Tackling The Iso 14000 Maze: Which Firms Adopt And Which Do Not?, Steven A. Melnyk, Robert Sroufe, Frank L. Montabon, Roger Calantone Nov 2000

Tackling The Iso 14000 Maze: Which Firms Adopt And Which Do Not?, Steven A. Melnyk, Robert Sroufe, Frank L. Montabon, Roger Calantone

Frank L. Montabon

ISO 14000 constitutes a major dilemma for most American firms in that they are not sure whether or not to actively pursue this new form of certification. This new standard is attractive as it holds the promise of helping firms become more efficient via better management of waste, yet this new standard deals with environmental performance, a potentially dangerous legal area. Both benefits and cost liabilities are very difficult to quantify and forecast. This leads to great uncertainty as to whether the benefits offered by improving environmental performance are sufficient to outweigh the costs incurred in obtaining certification. This study …
