Spatial Variations In The Intra-Urban Response To A Noise Source, Wilbur David Conder
Spatial Variations In The Intra-Urban Response To A Noise Source, Wilbur David Conder
Dissertations and Theses
Most research on the urban sonic environment has been recent. One finding has been that physical noise exposure indices calibrate poorly with human noise response. The vagaries of human response to noise have given impetus to research to isolate the factors that differentiate human response to noise. The present thesis continues this research.
The thesis specifies human noise response to occur on three levels: awareness, annoyance, and complaint. The factors that structure each level of noise response are identified in the published Iiterature.
Noise awareness is a function of noise exposure. Noise annoyance is a function of noise exposure to …
Solid Waste Disposal And Ocean Dumping, John William Sellers
Solid Waste Disposal And Ocean Dumping, John William Sellers
Marine Affairs Theses and Major Papers
A broad-scope overview of the solid waste disposal problem as intensified by legislation against ocean dumping of such wastes. Since the problem of increasing ocean pollution was partly solved by extensive restrictions on ocean dumping, wastes formerly disposed of in the oceans must now be disposed of by other methods. These alternative methods are discussed and cost estimates applied insofar as feasible; effects on the environment and on the conservation of natural resources are also discussed. Efforts should be directed to determine the level of solid waste disposal which would result in beneficial effects, or at the worst, in non-harmful …
A Field Study Of Selected Ecological Properties Of Boca Ciega Bay And Adjacent Gulf Of Mexico, Geo-Marine, Inc.
A Field Study Of Selected Ecological Properties Of Boca Ciega Bay And Adjacent Gulf Of Mexico, Geo-Marine, Inc.
Reports
This report describes a quantitative study of selected environmental parameters in a portion of Boca Ciega Bay and in the Gulf of Mexico adjacent to Johns Pass. The investigation included an analysis of hydrography and water quality during the period 14-20 February 1973. The objective of the study was to assess the present marine environment in order to judge the ecological feasibility of discharging tertiary treated sewage effluent into Boca Ciega Cay or secondary treated effluent into the Gulf of Mexico. The discharge would come from the proposed expansion of the South Cross Bayou sewage treatment plant.

Sensitivity Of Vertebrate Embryos To Heavy Metals As A Criterion Of Water Quality, Wesley J. Birge, John J. Just
Sensitivity Of Vertebrate Embryos To Heavy Metals As A Criterion Of Water Quality, Wesley J. Birge, John J. Just
KWRRI Research Reports
Embryonic and/or larval stages of the leopard frog (Rana pipiens), domestic fowl (Gallus domesticus) and the goldfish (Carassiua auratus) were treated with cadmium chloride, mercuric chloride, lead chloride, zinc chloride and sodium arsenite. The principal objectives were (1) to determine the sensitivity of vertebrate embryos to certain metals which are of consequence in water pollution, and (2) to ascertain the suitalility of vertebrate embryos as bioassay organisms for monitoring metallic pollutants within water resources. Vertebrate embryos are found to be highly sensitive to the toxic effects of all the metals studied. Concentrations of mercury as low as 10 ppb, with …

A Study Of The Dickey-Lincoln Hydroelectric Project And Its Impact On The Resources Of The Upper Saint John River Valley, Rosemary M. Manning, Sierra Club, New England Chapter
Dickey-Lincoln School Lakes Project
This report was under-taken primarily to evaluate the impact that the construction of the Dickey-Lincoln project would have upon the resources of the Upper St. John River, and to examine the assertion that the Dickey-Lincoln project constitutes a wise use of the public's environmental and economic resources. Since the case that has been made for the construction of the Dickey-Lincoln project rest primarily on the justification of the project in economic terms, this aspect of the project proposal will be intensively explored.

The Investigation Of Snowfall Rate Using Optical Techniques, Gerald J. Mulvey
The Investigation Of Snowfall Rate Using Optical Techniques, Gerald J. Mulvey
Atmospheric and Environmental Sciences Theses and Dissertations
Experiments involving the attenuation of light by falling snow, or hydrometeors in general, lend themselves to the study of at least two problems of meteorological interest. The first problem is that of visibility in adverse weather conditions, and the second is that of finding a better method to measure precipitation. From the late 1940's through the late 1960's, various investigators have attempted to apply forward light scattering theory in the geometric optics range (α ≥ 200, where α = (2π_r)/λ, λ=wavelength and r = radius)* to quantitatively describe the attenuation of a light beam, and thereby visibility changes due to …

This book is an attempt to present to the general public representative types of many of the conspicuous wild flowers found in Nebraska. These 260-some plants in no way constitute a flora of Nebraska which would number some 1,700 species of flowering plants. Included herein are both native and naturalized flowering herbaceous plants exclusive of the grasses and grasslike plants. Among these are plants that have had a long existence here and others which have recently invaded our area. Some are highly cherished and others are considered as common weeds. Excluded from this book are woody plants, such as trees, …
Social And Cultural Impact Of A Proposed Reservoir On A Rural Kentucky School District, Charles R. Smith, Philip Drucker
Social And Cultural Impact Of A Proposed Reservoir On A Rural Kentucky School District, Charles R. Smith, Philip Drucker
KWRRI Research Reports
This study utilizes anthropological concepts and research methods to study the educational system of a Central Kentucky school district with the goal of predicting the impact on it of a proposed multi-purpose (flood control, recreation, etc.) reservoir, and proposing options for forestalling dysfunctional aspects of that impact. The impact will result from the fact that although the county is now rurally oriented, the proposed reservoir will attract (has already begun to attract) urbanite residents from nearby Louisville, Kentucky's largest urban center, who can be expected to bring urban values concerning education, as well as other areas. To assess probable directions …
Sport Hunting As A Method Of Damage Control, L. Boddicker
Sport Hunting As A Method Of Damage Control, L. Boddicker
Great Plains Wildlife Damage Control Workshop Proceedings
Predator damage control is an area of concern to the livestock producer. He is also often the most likely person to choose sport hunting of coyotes as a recreational activity. Sport hunting of problem coyotes can be an effective tool.
Agricultural producers want to know the skills to control depredating wildlife. A high powered rifle, traps, and various related equipment are standard for most livestock production operations.
Through the Extension effort we attempt to help the producer develop wildlife damage control skills. It is also our responsibility to help develop alternatives to aid the livestock producer with persistent wildlife damage …
Crayfish, Leech, And Snail Control
Crayfish, Leech, And Snail Control
Great Plains Wildlife Damage Control Workshop Proceedings
We have effective results in controlling crayfish in our ponds using Baytex. Baytex is a higly toxic compound that effects the nervous system of many organisms. Used in small concentrations it will kill crayfish without hurting fish. We use Baytex at 40 ppb. We normally dilute the required amount of chemical with water and then mix it thoroughly in the pond. Leeches can be controlled using Dylox. Masoten is another trade name for dylox. The recommended rate of application is 1/2 ppm. This should be applied in a manner so it is thoroughly mixed in the ground. Recommened treatment for …

Great Plains Wildlife Damage Control Workshop Proceedings
During this workshop we have heard from some of the leading animal damage control and livestock management specialists in the Great Plains and adjoining states. It appears that western states personnel will likely be involved in wild animal damage control to a greater extent than before as control activities are passed from federal to the separate state agencies--hopefully, with financial assistance for both implementation and research.
There is no widespread agreement on numbers or severity of damage, or on the best damage control techniques to use. What works in one area of the country will not necessarily work in another. …
How Important Are Livestock Management Methods To The Orevention And /Or Reduction Of Losses To Coyotes, Don Good
Great Plains Wildlife Damage Control Workshop Proceedings
Professor.E. K. Faulkner, Extension Sheep Specialist from the University of Wyoming, stated that fencing the range was too expensive to be practical. He indicated that flares, pop-guns, color painting on sheep, and dogs have been used to cut down losses to coyotes but these methods have not been nearly so effective as the use of cyanide guns and 1080. He also indicated that losses to coyotes along with labor problems are the number 1 and 2 reasons for 200 sheepmen going out of the business the past 5 years in the range country. He said that shed lambing or lambing …

Extension Wildlife Damage Control In Arkansas, Rocky Lynch
Extension Wildlife Damage Control In Arkansas, Rocky Lynch
Great Plains Wildlife Damage Control Workshop Proceedings
With the curtailment of a service type predator control program that existed in Arkansas for 29 years, the Arkansas Game and Fish Commission in 1970 initiated a Nuisance Animal Control Section within the framework of the Commissions' Game Division. This extension - demonstration type wildlife control unit was named such because of the increase in rodent control (beaver and muskrat) within the state. Their numbers were spawned by the habitat inhancement in the delta and timber growing regions of Arkansas.
A Game Biologist visited the Missouri Department of Conservation and observed the technique of their predator control agent. With ideas …

A Eutrophication Model Of The White River Basin Above Beaver Reservoir In Northwest Arkansas, Robert A. Gearhart, Dee Mitchell, Louis Thibodeaux, Richard Meyers
A Eutrophication Model Of The White River Basin Above Beaver Reservoir In Northwest Arkansas, Robert A. Gearhart, Dee Mitchell, Louis Thibodeaux, Richard Meyers
Technical Reports
With national interest focused on man’s ever increasing degradation of the waters in this nation, it is clearly evident that an accurate assessment of all parameters influencing water quality needs to be made. Moreover, nutrient levels and budgets reflecting eutrophication trends are important parameters in the overall factors effecting water quality in lakes and reservoirs. The ability to predict future eutrophication levels will greatly enhance the retardation of the eutrophication process. Through mathematical simulation of this process, eutrophication can be analyzed and intelligent decisions regarding water quality management can be made.
A Study To Improve Dissolved Oxygen Analysis Techniques To Facilitate Water Quality Field Survey Applications, R. W. Raible, M. K. Testerman
A Study To Improve Dissolved Oxygen Analysis Techniques To Facilitate Water Quality Field Survey Applications, R. W. Raible, M. K. Testerman
Technical Reports
This report describes studies made of the temperature characteristics of dissolved oxygen electrodes having a large surface area. Large area electrodes proved to have much longer lifetime between rejuvenations. Many measurements of dissolved oxygen in water need to be made in field situations where recalibration techniques would be difficult and where making temperature corrections is time consuming for operators who may be making numerous measurements. This study was directed toward design of a compensation circuit for a dissolved oxygen electrode which will give the best possible measurement over a large water temperature range of 5° - 35°C without the necessity …
Animal Damage Control In South Dakota, V. Van Ballenberghe
Animal Damage Control In South Dakota, V. Van Ballenberghe
Great Plains Wildlife Damage Control Workshop Proceedings
South Dakota, like virtually all other states, is subject to economic losses from wildlife depredations. We have been in the government sponsored, animal damage control business perhaps longer than some states - our history dates back to the time of Three-toes and the Custer Wolf. In 1973 we are still in that business, perhaps more intensively than ever before, and we regard animal damage control as one of the most pervasive and difficult to solve wildlife problems facing us.
The Missouri River bisects South Dakota into approximately equal "East River" and "West River" land areas. These differ ecologically, and to …

Media use should not be a half way activity done after everything else on your mind is taken care of. The key word is commitment--if you are not ready to give proper preparation which includes understand what each (newspaper, radio, TV, etc.) does best, then don't do anything. There is at least a certain minimum quality standard that must be met--anything less and media exposure can hurt you and your program rather than help you. Seek help. Then select the media to fit your time, money and inclination. Example: Even if you don't buy time--television properly done may cost much …
