Microbial Characteristics Of An Industrial Mixed Liquor After Exposure To Phenolic Compounds, Patricia L. Boyle
Microbial Characteristics Of An Industrial Mixed Liquor After Exposure To Phenolic Compounds, Patricia L. Boyle
Theses
The microbial characteristics of a mixed population from the Passaic Valley Sewerage Commissioners (PVSC) Wastewater Treatment Plant in Newark were examined. This plant handles about 250 million gallons per day of mixed sewerage, with a large industrial component. The microbial species were characterized using standard plating techniques, morphology, microscopic observation, and biochemical tests. These characteristics were determined for the fresh liquor, and after successive batch exposure to phenol (100 ppm) and 2-chlorophenol (20 ppm). Predator/prey, gram positive to gram negative bacteria ratios, and the fungi and protozoan populations were also determined. These results were compared with those previously obtained using …
Reaction Of Atomic Hydrogen With Chloroform In A Discharge Flow Reactor, Wan-Kuen Jo
Reaction Of Atomic Hydrogen With Chloroform In A Discharge Flow Reactor, Wan-Kuen Jo
Theses
The reactions of atomic hydrogen with chloroform were studied in a tubular flow reactor both in a 4 cm i.d. and 2.6 i.d. discharge flow reactor at pressure of 2.22 to 2.82 mmHg and room temperature using GC and GC/MS for analysis of the reaction. The hydrogen atom concentration at the reaction flame was measured by Chemiluminescence titration with nitrogen dioxide. The hydrogen concentrations are in the 2.48 x 10+14 to 4.83 x 10+14 atoms/cc range at six different hydrogen flow rates. Evidence was found for the formation of atomic carbon intermediate in the reaction, but methane was …
Random Genetic Drift Diffusion Model And Deterministic And Stochastic Models Of Epidemics, Norman W. Loney
Random Genetic Drift Diffusion Model And Deterministic And Stochastic Models Of Epidemics, Norman W. Loney
Theses
In the Random Genetic Drift Diffusion model two approaches are taken. First we examined a discrete model that represent a relatively idealised version of the phenomena. Hefurther make the assumption that the Population reproduces itself and then dies, thus maintaining a finite population size at all times. If at a given locus there are two possible allels A and B and if X(t) is the number of A type in the genetic pool of size 2N, then 2N-X(t) is the number of B type. We then proceed to obtain a probability density function of X( t) by an Exact method …
