Environment And Communiy Organization In Grasslands Of Canyonlands National Park, Edgar F. Kleiner, K. T. Harper Jan 1972

Environment And Communiy Organization In Grasslands Of Canyonlands National Park, Edgar F. Kleiner, K. T. Harper

Canyonlands Research Bibliography

Sixty uniformly distributed stands in adjacent areas, 40 in Virginia Park (virgin) and 20 in Chesler Park (grazed), were analyzed. Cryptogamic and vascular species were recorded; cover was analyzed by the point sampling method, and frequency by means of 25 quadrats (each 0.125 m^2) per stand. The prevalent species (26 in Virginia, 23 in Chesler) were selected on the basis of a constancy-times-frequency index. Interspecific association patterns were determined by means of simple procedures based on quadrat frequency values for each species in the individual stands. Major environmental variables were recorded at each stand, and soil samples from four depths …

Agriculture And Pollution In Western Australia. Part 1. Background, C V. Malcolm Jan 1972

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.


Wastewater Treatment Plant Control, David Milton Knowles Jan 1972

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.

Remote Sensing Of Environmental Parameters, Wendell Princeton Perkins Jan 1972

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.


Localized Wastewater Treatment Facilities, Robert Russell Garrett Jan 1972

Localized Wastewater Treatment Facilities, Robert Russell Garrett

Retrospective Theses and Dissertations

The report describes an alternative to the use of septic tanks for invidual dwellings. The major problems confronting the larger wastewater treatment plants (0.012 to 10 million gallons per day) in central Florida are also discussed. Solutions in this report are for individual and multi-unit dwelling treatment systems (to 0.06 MGD). these units can provide 90% biochemical oxygen demand (BOD) and suspended solids (SS) removal in accord with new state and county regulations. A comparison of the large versus the small plants reveals that small innovative plants, though more expensive, are more environmentally sound than the poorly operated large facilities. …
