Indicators Of Microbial Activity In Biological Treatment Of Hazardous Wastes, Alexander Mclean Sherrin

Theses

Three methods were used to measure the activity of mixed liquor from the Livingston, N.J. municipal wastewater treatment plant on exposure to phenol. The three methods were, substrate removal rate (SRR), dissolved oxygen uptake rate (DOUR), and the dye reduction rate (DRR). Parameters from each test were compared for reproducibility and ease of determination. The SRR test gave the most reproducible results, while the DOUR test was the least reproducible. Although the reproducibility of the DRR test was close to that of the SRR test, the DRR was more time consuming and required a greater degree of expertise and training. …

Process Hazard Review For Drug Development, Rudolph R. Schwarz

Theses

The development of drugs has become increasingly complex, requiring the use of a wide variety of pharmaceutical actives and isolated intermediates, a majority of which are not always completely characterized with respect to their hazard potential. This can present a source of potential exposure to those who handle these substances during initial drug development, manufacturing of the drug active and ultimately the finished pharamaceutical product. It is, therefore, essential that safety and health information be documented and communicated during the entire drug development process.

The need for application of process hazard review techniques to the development of new drug materials …

Construction Labor And Productivity : Productivity Improvements, Stavros C. Nicolaou

Theses

Construction productivity has been on the decline in the last decade.

A Study Of The Dynamics Of Microbial Competition For A Single Resource In A Chemostat Between Reversible Attachment To Solid Surfaces, Pericles Theofilos Lagonikos

Theses

It is known that two microbial populations competing for a single non-renewable resource in a homogeneous environment with time-invariant inputs cannot coexist in a steady state. The case where two microbial populations exhibiting reversible attachment to the walls of a chemostat compete for a single resource is studied theoretically. Because of the cell's attachment to the walls, the environment is no longer homogeneous. The present study considers the case where the attached cells form no more than a monolayer. The Baltzis-Fredrickson model is used to represent the attachment to the walls. In one system the attachment of cells of the …

Particle Size Distribution In Isothermal Batch Emulsion Polymerization, Bhavin R. Patel

Theses

A detailed modified mathematical model for particle size distribution in isothermal batch emulsion polymerization of Styrene and Vinyl acetate is proposed on the basis of the population balance approach in presence of several kinetic and mass transfer processes. This study is limited to Smith-Ewart's case II, which assumes instantaneous free radical termination within the polymer particles. Radical desor¬ption mechanism from polymer particles is included in the model and the desorption rate is formulated from the diffu¬sion theory which suggests that the rate co-efficient should be inversely proportional to the surface area of polymer particles.

Theses

The work undertaken in this thesis is in two parts. In the first, the structure and heat of formation of substituted cyclobutanes were studied via the computer program MMII using an IBM PCXT personal computer with a math co-processor chip. Structurally, a trend was seen to be followed in which bulkier substituents were pushed away from any steric interaction with the ring. This was accomplished by having the latter alter its puckering angle, C2C1C4 angle, HCX angle, and to a smaller extent, the bond lengths immediately adjacent to the substituted carbon atom. This results demonstrated that the ring was very …
