biophysical evaluation of an evaporatively-cooled water bag,

commercially available flax canvas water bags were evaluated for their ability to cool drinking water by evaporating water from their outer surfaces. evaluations were conducted in an environmentally-controlled chamber under various climatic conditions different ambient temperatures, relative humidities and wind velocities were utilized to..

thermal effects on cellulosic materials, thermal effects on cellulosic materials from nuclear explosions

the project had as its primary objectives the determination of (1) the minimum thermal-ignition energies for fine kindling fuels and (2) the depth of char in wood as a check on equations developed from laboratory data obtained with a carbon arc. test specimens of alpha-cellulose paper of various thicknesses, densities, and carbon contents..

control of air emissions from hazardous waste combustion sources: field evaluations of pilot-scale air pollution control devices,

pilot scale air pollution control devices supplied by hydro-sonic systems, ets, inc., and vulcan engineering company were installed at the ensco, inc. incinerator in el dorado, arkansas, in the spring of 1984. each of these units treated an uncontrolled slipstream of the incinerator exhaust gas. simultaneous measurement of the total parti..

electronic structure of neutral and singly ionized curium

extensive observations and analyses of the emission spectra of neutral and singly ionized curium, cm i and cm ii, have resulted in the determination of 785 cm i and 598 cm ii energy levels. these levels then combine to classify 9145 of the more than 14,250 lines of sup 244 cm observed between 240 and 2650 nm. most of the levels have lande..

design of a condenser-boiler for a binary mercury-organic rankine cycle solar dynamic space power system. final rept

a theoretical design was performed for the condenser/boiler of a space-based solar dynamic power system. the base system is a binary rankine cycle with mercury and toluene, as the working fluids. system output is 75 kwe with a combined efficiency of 41.1. design goals were to develop the most reliable, mass efficient unit possible for del..

injury and yield response of cotton to chronic doses of ozone and sulfur dioxide. journal article reprint: injury and yield response of cotton to chronic doses of ozone and sulfur dioxide

knowledge of relationships between chronic doses of o3 and crop yield is required to set air quality standards that protect agricultural interests and to determine the need to develop resistant cultivars of sensitive species. open-top field chamber studies have provided some information of this type for a few crop species including one we..

changes in aboveground biomass and nutrient content on walker branch watershed from 1967 to 1983

the increment of forest biomass and nutrient content on walker branch watershed, tennessee, from 1967 to 1983 was interrupted by two insect outbreaks. an outbreak of the southern pine beetle in the early 1970s and an outbreak of the hickory borer in the late 1970s to early 1980s killed a number of shortleaf pine (pinus echinata) and hicko..

study of multireservoir operation with minimum desirable flow constraints,

the study concerns the operation of the three-reservoir system of the upper cottonwood-neosho river basin under the constraints of minimum desirable in-stream flows as specified in the kansas state water plan in addition to committed conservation storages for water supply. the water problem is formulated as a chance-constrained optimizati..

test method evaluations and emissions testing for rating wood stoves. final rept. jun 85-apr 86

the report gives results of a comparison of three sampling methods for wood burning stoves: the epa modified method 5 (mm5), the oregon method 7 (om7), and the astm proposed method p180. it also addresses the effect that emission format (grams per hour, grams per kilogram wood burned, micrograms per joule heat output) has on the intermeth..

industrial scale peat use demonstration at syl laskin steam electric station: final report

minnesota power and the minnesota department of natural resources conducted the industrial scale peat use demonstration in 1985 at the syl laskin steam electric station. the station is located near hoyt lakes, minnesota. the two unit station commissioned in 1951 was designed to fire bituminous coal. its current capacity is 88 mw (2 units ..
