These studies have led to the conclusion that silver iodide used for cloud seeding poses no immediate threat to either people or the ecosystem in general. However, since most of the data have been obtained over the relatively short time span of the l

On January 1978, a hearing was held by the Wisconsin State Assembly Agricluture Committee which considered a bill to prohibit weather modification in Wisconsin. A statement was made during this hearing which suggested that if dry ice were to be used

At the Wisconsin State Assembly Agriculture Committee hearing on 11 January 1978 it was reported that samples of precipitation were collected within the target area for cloud seeding with silver iodide by Shower Power, Inc. Subsequent analyses of the

A sodium-based flue gas desulfurization process, employing reductive burning and a Claus recovery system, has the advantage of producing elemental sulfur as a byproduct. This study optimized the process conditions for two steps in the proposed reacti

Color and chemical oxygen demand (COD) in bleach plant effluents are of concern. Acidified flyash can effectively remove both color and COD from caustic bleach plant effluents. Equally effective, but quicker and easier, is to acidify the effluent to

The majority of sodium sulfite pulping liquor recovery systems are based on the reductive burning of the spent liquor, followed by acidification of the resulting smelt solution by CO[sub 2]. This study investigated a number of the physical and chemic

The extent of conversion of Na2S to H2S in a concentrated aqueous solution of sodium sulfide and sodium carbonate undergoing carbonation can be monitored by measuring the pH and conductivity. A simple linear equation has been developed to correlate t

A modification of Lean's (1973 a,b ) four-compartment model of the transfer of phosphorus between soluble and particulate forms in the epilimnion of lakes is necessary to make the model consistent with certain observed transfer curves. By splitting t

Results of neutron activation analyses for Sc and Fe in 76 samples of igneous and sedimentary rock, including 9 composites, are reported. The highest Sc contents (average, 30–40 ppm) were found in basalts and gabbros and the lowest in nepheline sye
