Electroprecipitation of Phosphate from Sewage
A study of phosphate removal from secondary sewage effluent was conducted using a two-step method of electroprecipitation followed by lanthanum chloride precipitation. In the first step,...

Use of Irradiation in Plastic Wastes Disposal
The feasibility of utilizing irradiation to assist in plastic waste disposal was investigated. This was based on the observation that most plastic materials become brittle upon irradiation....

Transport Equation Stability and Estuary Modeling
A method is presented for judging the stability of discrete approximations to the estuary mixing equations. It is applicable to unequal as well as equal reach lengths. A mathematical model...

Control of Natural Chloride, Arkansas-Red Rivers
Natural mineral pollution si rendering water unusable in portions of the Arkansas and Red River Basins. Stream flows are high in chloride because of brine springs and seeps emitting directly...

Carobn-14 Ages Related to Occurrence of Salt Water
Under native conditions Hilton Head Island, SC, the original regional flow path was northeastward (generally from the south end to the north end of the island). At the south end, the fresh...

Leaching of Pollutants from Refuse Beds
A procedure is presented for estimating theoretically the chemical quality of leachates from sanitary landfills. A theory of column chromatography was employed to determine the leaching...

A Water Quality Model of Chlorides in Great Lakes
The increase in the concentration of conservative substances in the Great Lakes is described by a simple time variable equation. The concentration of chlorides is related to the fresh...

Chloride Control - Arkansas and Red River Basin
Natural brine emissions are found to be the principal cause of water quality degradation in the Arkansas and Red River Basins. The methods used to identify the brine emission sources are...

Viscoelastic Wave Interaction with Cylindrical Cavity
Stresses at a free-field point and on the boundary of a circular hole in a viscoelastic plate subjected to air shock loading were determined by photoviscoelastic and moiré methods. The...

Effect of Boundary Conditions on Shell Buckling
The results of an experimental study on the influence of boundary conditions on the elastic buckling behavior of spherical shells are presented. Eighty-seven uniform pressure tests on...
