Nitrate Plus Nitrite Concentrations In A Himalayan Ice Core, William Berry Lyons, Paul Andrew Mayewski

Earth Science Faculty Scholarship

The measurement of chemical constituents in glacial ice has been useful in discerning historic trends in chemical deposition and hence paleo-atmospheric records in remote areas (Thompson and Mosley - Thompson, 1981; Johnson and Chamberlain, 1981; Ng and Patterson, 1981; Neftel et al., 1982). However, delineating the sources of the deposited chemical species in question is not always straightforward. This has been especially true for nitrate. Although it is now believed that man-made emissions are responsible for a high percentage of nitrate being deposited in remote areas of the Northern Hemisphere, numerous natural sources, named and unnamed, have also contributed to …

Variability Of Atmospheric Hydrocarbon Concentrations And Deposition Rates, Charles Thomas Farmer

OES Theses and Dissertations

The atmospheric hydrocarbon concentration was determined at various locations throughout Southeastern Virginia from July 1981 to February 1983. During this period the concentration ranged from 0.4 to 5.5 μg/m³ . From October 1982 to February 1983, WET and dry deposition samples were collected in conjunction with these air samples. Total hydrocarbon dry deposition rates ranged from deposition rates ranged from 4 to 189 μg/m² /day, while WET 22 to 670 μg/m² /day. Hydrocarbon concentrations found were within the ranges reported in the literature for wet, dry and atmospheric hydrocarbon concentrations.

Linear trend analysis revealed no correlation between …

Industries Assistance Commission Inquiry Into Drought Assistance, Department Of Agriculture And Food, Western Australia, Australia. Industries Assistance Commission, J. Ripley

All other publications

This submission outlines the extent of drought in Western Australia in 1982/83, examines the adequacy of drought assistance measures and, after canvassing alternative assistance measures, proposes a preferred package of drought assistance measures.

The issue of whether or not the non-farm sector in rural areas should receive drought assistance, and if so what type, is not addressed in this submission. Rather the framework of discussion is restricted to the farm sector.

Limiting Swine Stress With Evaporative Cooling In The Southeast, Robert L. Fehr, K. T. Priddy, Samuel G. Mcneill, Douglas G. Overhults

Biosystems and Agricultural Engineering Faculty Publications

Three-hourly weather data for 7 locations in the Southeast and Central United States were used to evaluate the feasibility of evaporative cooling for reducing swine stress. Stress was defined as a relationship between dry and wet bulb temperatures which exceeded a stress index of 85. This analysis indicates that properly installed evaporative coolers could reduce the number of hours that stress would occur in swine facilities from 89.6 to 96.4% depending on location.

Sixty-Day Temperature Persistence At Five-Day Intervals For Minneapolis-St. Paul, Charles J. Fisk

Journal of the Minnesota Academy of Science

The annual course of 60-day temperature persistence for Minneapolis-St. Paul, Minnesota is examined at five -clay intervals for the last 110 years. Results show maximum persistence for the 60-day periods February 20 to April 20 and June 25 to August 23. Minimum persistence is observed for sequences whose midpoints correspond to late April, late September and mid-November. This suggests the presence of a single favored regime-breaking period for the winter to summer transition and two such periods for summer to winter.
