Reductive, dechlorination of sediment-sorbed polychlorinated biphenyls by vitamin B₁₂(subscript s)

Creator:: Trobaugh, Darin James
Abstract:: The reductive dechlorination of chlorobiphenyls in sediment by titanium(III) citrate-reduced vitamin Bus was studied in batch reactors. Long term ampoule studies demonstrated reductive dechlorination of sediment-sorbed 2,3,4,5,6-pentachlorobiphenyl (2,3,4,5,6-PeCB) to tetra-, tri-, di-, and monochlorobiphenyl products. Over 50% chlorine removal was observed over 160 days. The results of the ampoule experiment...

Behavior of cellular bulkheads in deep sands

Creator:: Maitland, James Keith
Abstract:: Large-scale experiments on circular model cell bulkheads were conducted to define the distribution of hoop stresses, deflections of the cells, distortion of the cell fill, ultimate overturning resistance, and the critical mode of failure. The embedment depth of the model cells was varied to investigate the effect of embedment on...

Biodegradability and oxygen uptake studies on resuspended estuarine bottom sediments

Creator:: Touhey, Robert James
Abstract:: A study was conducted to determine the oxygen uptake rate of resuspended estuarine bottom sediments and the biodegradability of the organic matter released during resuspension. Oxygen uptake was measured on a Gilson Differential Respirometer and the percent biodegradability was calculated by determining the soluble organic carbon on a Beckman Carbonaceous...

Polar analysis of beam-columns for aircraft

Creator:: Jones, Walter Richard
Abstract:: The analysis of a member carrying a combination of lateral and axial loads (a "beam-column") is a problem of frequent occurrence in aircraft structural design. This thesis presents the derivation and application of the Polar method, both analytical and graphical. The method was first suggested in Germany, several years later...

Evaluating dairy waste management systems ̓influence on fecal coliform concentration in runoff

Creator:: Grismer, Mark Edward
Abstract:: This paper examines the environmental factors influencing the die-off and transport of fecal coliform bacteria present in wastes applied to the land surface. These factors are examined specifically for dairy waste management systems and the net effect each system has on runoff water quality. A model is developed that considers...

The effect of elevated pressure on the activated sludge process

Creator:: Godsil, Patrick James
Abstract:: A study of the effect of elevated pressure on the activated sludge waste treatment process is presented. The method of study involved a comparison of two laboratory, batch type, activated sludge units. One unit was operated at atmospheric pressure as a base control and the other operated at elevated pressures...

Foam separation of organic and toxic materials in kraft mill effluents

Creator:: Blazier, James Lewis
Abstract:: Because of the organic nature and the natural foaming characteristics of kraft mill effluents, it was decided to investigate the feasibility of using foam separation as a method of treatment. The treatment efficiency was evaluated by BOD and COD reductions as well as the decrease in toxicity to marine life....

Air photo analysis of waste dispersion from ocean outfalls

Creator:: James, Wesley Pierce
Abstract:: Aerial photography provides a method of analyzing dispersion of wastes that are discharged into the ocean. This method is more comprehensive than conventional boat sampling in dispersion studies. The photographic technique permits waste concentrations to be measured throughout the plume in one instant; thereby allowing the diffusion analysis to be...
