Fisheries Report No 11 - The Fauna, Flora And Planned Usage Of The Dampier Archipelago, A. A. Burbidge, R. I. T. Prince

Fisheries Research Reports

The Dampier Archipelago is a group of islands off the north west coast of Australia (20 20! - 20 45'S, 116 Cast . 117°E), first discovered by William Dampier in 1699 and subsequently named after him by the Baudin expedition of 1801. This name has since been applied by some authors to include all islands from Roebourne to North West Cape, including both Barrow Island and the Monte Bello Islands, but it is more correctly applied to those islands within a 30 mile radius of the town of Dampier.

Ir. recent times, three parties have visited the Archipelago and examined …

An Argument For The Open Ocean Siting Of Coastal Thermal Electric Plants, Clarence M. Tarzwell

United States Environmental Protection Agency: Publications

A great deal of research is yet to be done before we will definitely know all the effects of thermal electric generating plants. It is evident, however, that the chlorination of the intake water is definitely lethal to a high percentage of planktonic and other organisms; that thermal shock is detrimental to some of the more sensitive forms; that the continued exposure to high temperatures after thermal shock is lethal to many forms, especially the zooplankton; that the screening and turbulence in such plants is lethal to larval fishes and several invertebrates, and that immense amounts of waters are put …

Diffusion-Controlled Reaction Kinetics, David Peak, J W. Corbett

All Physics Faculty Publications

The theory of diffusion-controlled correlated reaction kinetics is developed for the radiation boundary condition (RBC) at the reaction surface. Limited only by the assumptions of purely radial spatial dependence, of a spherical reaction surface, and of continuum diffusion, these results comprise a complete solution for these kinetics. The limiting solutions are obtained for the case of the Smoluchowski boundary condition (SBC) at the reaction surface; numerical solutions are presented, as are the analytic forms of certain limiting cases. The initial recovery for the RBC is linear in time, whereas for the SBC it is well known to be proportional to …

Agriculture And Pollution In Western Australia. Part 1. Background, C V. Malcolm

Journal of the Department of Agriculture, Western Australia, Series 4

For centuries there has been awareness of pollution but it has received dramatic publicity in recent years.

In Western Australia, provisions for its control are written into the Health Act and many other Acts besides the Environmental Protection Act of 1971.

A number of factors have acted worldwide and locally to increase awareness and concern about pollution, and to justify careful examination of the problems it causes.

Studies To Develop And Investigate An Inverse Formulation For Numerically Solving Three-Dimensional Free Surface Potential Fluid Flows, Roland W. Jeppson

Reports

An inverse formulation is developed for solving three-dimensional potential fluid flows which considers the magnitudes of the cartesian coordinates x, y, and z as the dependent variables in the space defined by the potential function and two mutually orthogonal stream surface functions whose intersection defines the physical space streamlines. This formulation reverses the usual role of the variables. In this inverse space irregular boundaries, with unknown position in the physical space, such as free surfaces become plane boundaries, and the space of most potential flow problems is a parallelepiped. The basin partial differential equations resulting from this formulation are nonlinear …

The Hydraulics Of Waste Stabilization Ponds, Gary Z. Watters

Reports

The treatment efficiency of waste stabilization ponds depends primarily on the biological factors of type of waste and organic loading. However, the biological activity in a pond is greatly influenced by the environmental conditions of temperature, wind, sunlight, and the hydraulic flow patterns. In the past little attention has been given to the hydraulic characteristics of waste stabilization ponds such as the gross flow patterns within stabilization ponds as affected by the shape of the pond or lagoon, the presence of dead spaces, and positioning of inlets and outlets and the degree of density stratification. These hydraulic flow characteristics will …

Wastewater Treatment Plant Control, David Milton Knowles

Retrospective Theses and Dissertations

This report is the result of investigation of the feasibility of increasing the use of autamatic controls at the Florida Technological University Wastewater Treatment Plant. This investigation was to include a literature search and visits to wastewater treatment plants. During the writers course of study, he was privileged to make a series of tests of a residual chlorine analyzer which was made in the school shop. Since this work was closely related to automatic controls the data are included in this report.

Solid Waste Management At Florida Technological University, Robert F. Hever

Retrospective Theses and Dissertations

This paper is a report on a study of the management of solid wastes at Florida Technological University (FTU). This study endeavors to provide a basis for effective planning for disposal of FTU's solid wastes, both in the next few years and at the time of maximum FTU population. Essentially, the study affirms that the present system of refuse collection by a private contractor is the best method of disposal, with the possibility that recycling of mixed paper may become feasible at some future time.

Remote Sensing Of Environmental Parameters, Wendell Princeton Perkins

Retrospective Theses and Dissertations

Atmospheric pollution in some degree has been around since time began. In recent times it has reached levels in some areas which proved to be harmful to man's health. A brief history review of these occurrences is presented. Laws have been enacted to combat this threat. A brief review of these laws is presented. Instruments for remote sensing of polluting sources are being developed to monitor ambient air quality and aid in enforcing these laws. A review of the techniques employed and the present state of the art is explored. Available instruments are presented in section III-5.

Conversion And Validation Of Sigart Program, A Progressive Traffic Signal Lights System Computer Model, Dennis F. Troyan

Retrospective Theses and Dissertations

The purpose of this research paper was to translate a Computer Model (SIGART), capable of simulating a progressive traffic signal lights system, from Burroughs B5500 FORTRAN II to the IBM 360 FORTRAN IV computer language, to outline the program algorithm, to set up detailed program documentation and to validate this model by applying practical system data. Expansion of the SIGART program by addition of an option to produce a time space plot of the output data utilizing a Calcomp plotter was also to be considered.

Reaction Of Aqueous Catechol Solutions With Minerals, Boonthong Poocharoen

Dissertations and Theses

The effectiveness of catechol, an aromatic vic-diol, in dissolving silicate minerals was studied. A synthetic amorphous magnesium trisilicate, Mg₂Si₃O₈∙5H₂O, as well as the minerals olivine, sepiolite, diopside, augite, and enstatite were used to react with catechol in slightly acidic, basic, and neutral solutions. It was found, depending on the solvent used, that 33-52, 8-17, 14-30, 5-11, 3-6, and 0.5-1 % of the minerals dissolved, respectively.

The reaction with Mg₂Si₃0₈·5H₂0 resulted in the formation of crystals of magnesium tris (catecholato) siliconate nonahydrate Mg[Si(Cat)₃]∙9H₂0. Dehydration of the crystals at room temperature resulted in the loss of 6 moles of water to form …
