Evaluation Of Cattle Use Of A Deer Winter Range In The Black Hills, David C. Hamm

Electronic Theses and Dissertations

Cattle use of a deer winter range in the Black Hills was investigated during the summer grazing seasons of 1971-1972. A U.S. Forest Service grazing allotment situated between Mystic and Redfern, South Dakota, was used as the study area. The allotment was divided into five grazing units or pastures managed collectively under a “rest-rotation” system of grazing. Three study sites were selected in each unit of the allotment, and 75 exclosures were erected on each site; a paired-plot method was used to collect data. Indices to use of sites by deer and cattle were obtained by counts of deer pellet …

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 …

A Study Of Organochlorine Insecticides In Freshwater Crayfish -- Analytical Problems And Biomonitoring Survey, Robert C. Vanderjack

Masters Theses

Crayfish were collected from 3 sites on Polecat Creek, Coles County, Illinois in early spring, early summer, and late summer of 1972. Pesticides were extracted from the crayfish tissue in a one step procedure utilizing a Florisil elution column. Analysis was by electron capture gas chromatography. Pesticide residues in the nannogram range were analyzed and background contamination was an important consideration. Sources of background contamination were investigated and teflon stopcocks, Florisil, and residues on “cleaned” glassware were found to be major contamination sources. Distilled water used in flushing glassware should also be considered a potential contamination source.

Chemical Survey Of Selected South Dakota Lake Sediments, Alan Ross Swanson

Electronic Theses and Dissertations

Available phosphorus, organic carbon, and organic nitrogen were measured in bottom sediments of 16 lakes and ponds in northeast South Dakota. These lakes were glaciated, relatively shallow, and productive. Ranges of the surface sediments were: available phosphorus, 2 to 42 ppm; organic carbon, 0.94 to 5.34 percent; and organic nitrogen, 0.29 to 0.79 percent. Ranges of subsurface sediments were: available phosphorus, 2 to 39 ppm; organic carbon, 0.54 to 6.06 percent; organic nitrogen, 0.19 to 0.88 percent. Concentrations in most lakes varied little from top to bottom. Hard-bottomed lakes generally decreased in nutrient concentrations from sediment surface of subsurface. Lower …

Origin And Transport Of Nutrients In The Upper Big Sioux River, South Dakota, Charles William Thompson

Electronic Theses and Dissertations

The upper Big Sioux River Basin, in northeastern South Dakota, was studied to determine the origin and transport of nutrients in the Big Sioux River. The area was divided into three segments. Two of the segments, the Big Sioux River and Willow Creek Basins, were primarily agricultural drainage areas, and one segment was the city of Watertown. Sampling stations were selected to facilitate the determination of nutrient inputs to the river from each of these segments and to determine the nutrient load in the river leaving the study area. Nutrients studied included total orthophosphate and the particulate and dissolved fractions …

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 …

The Sport Hunting Of Coyotes, Edward L. Kozicky

Great Plains Wildlife Damage Control Workshop Proceedings

In an effort to gain some insight into the sport hunting of coyotes in Kansas, Bob Henderson circulated 586 detailed questionnaires and received 228 replies--an excellent voluntary response.

Time does not permit detailed comments on each question and reply. We shall only hit the highlights, and add some editorial comment where it seems appropriate.

It should be remembered that those who took the time to answer the 35 questions were devotees of the sport. This point is emphasized by the fact that of the 225 hunters who responded, 95 have been hunting coyotes for 20 years or more. The next …

Modification Of A Continuous Ice Crystal Replicator, Paul D. Thornley

Reports

A continuous ice-crystal replicator was modified by the addition of a gear drive to the cating wheel. This modification utilizes a positive drive force on the coating wheel rather than the friction force between the coating wheel and the film. The coating wheel operates successfully for at least 12 hours without slippage or damage to the film. Studies have uncovered several deficiencies in the replicator design which could be corrected. The correction of these deficiencies would lead to an improved quality of ice-crystal replicas. The need for continued studies in the fluid properties of Formvar solution is pointed out. Information …

Computer Simulation Of The Hydrologic And Salinity Flow Systems Within The Bear River Basin, Robert W. Hill, Eugene K. Israelsen, J. Paul Riley

Reports

Accompanying the increased use of water resources is an increases accumulation of chemical pollutants. Te prevent degradation of the water resources beyong useful limits, pollution inputs from additional uses must be quite accurately predicted prior to implementation of the new use. The model described in this report was formulated to provide the required predictive capability for the Bear River Basin. Modeling concepts of the hydrologic system are based upon the development of basin relationships describing the hydrologic processes which are linked together by the countinuity-of-mass principle. The salinity flow system is then linked to the hydrologic system based on the …

Sorption Kinetics Part Ii: Modeling Longitudinal Concentration Profiles In A Packed Bed Reactor, David W. Hendricks

Reports

A mass balance simulation model for sorption in a packed bed reactor was developed. All of the terms in the model, consisting of constants of the porous media, and functions, were evaluated by independent laboratory studies. The kinetic term was determined in Part I. Two numerical schemes (an explicit scheme and an implicit scheme respectively) with corresponding computer programs were developed and made operational. They were not tested against laboratory column results due to long times necessary on the computer and corresponding high costs. Laboratory testing consisted of measuring column profiles for six different packed columns at different flow rates …

Ecological Implications Of Dimethyl Mercury In An Aquatic Food Chain, Lawrence P. Kolb, Donald B. Porcella, E. Joe Middlebrooks

Reports

Laboratory studies indicate dimethyl mercury may be a major product of microbial methylation of inorganic mercury. Although another methylation product, monomethyl mercury, has been extensively studied, the physical, chemical, and biologicl factors affecting the transport and food chain distribution of dimethyl mercury have remained unclear. This report presents results of laboratory studies of volatilization rates from water as a function of temperature and mixing conditions, uptake kinetics and equilibrium concentrations in algae,

Sorption Kinetics Part I: A Laboratory Investigation Of Six Proposed Rate Laws Using Batch Reactors, David W. Hendricks, Laxman G. Kuratti

Reports

Six proposed rate equations for sorption kinetics have been investigated by laboratory batch experiments involving some 270 individual “runs” to determine sorption uptake with time for varying conditions of initial sorbate concentration, temperature, and sorbent species. The sorbate selected was rhodamine-B dye, used because it will sorb readily and is easily measured. Two sorbents, Dowex 50 resin, and Filtrasorb 200 activated carbon were used. Temperature conditions were 10, 20, 30, and 40°C, and concentrations ranged from .0008 to 400 micrograms per ml, rhodamine-B. Analysis of data was computer automated, requiring as input only test conditions, instrument readings, dilutions, and corresponding …

Integrated Measurement Of Soil Moisture By Use Of Radio Waves, Duane G. Chadwick

Reports

An integrated value of soil moisture can be determine dby measuring the attenuation of vertically-polarized surface radio waves taht are propagated over the ground between a transmitting and receiving atenna. Soil moisture values in the root-zone region were measured over longitudinal distances typically ranging from 50 feet to 600 feet with good results. Integrated soil moisture measurements over greater distances are also possible. Received field strength of propaged radio surface waves closely matches theoretical calculations. The measurement is easily made and does not disturb the soil. Dense, green vegetation, such as alfalfa or corn, causes errors in measurement accuracy. Less …

Solving Three-Dimensional Potential Flow Problems By Means Of An Inverse Formulation And Finite Differences, Allen L. Davis, Roland W. Jeppson

Reports

A finite difference method is developed to solve the three-dimensional, steady, incompressible, potential flow equations obtained by using a potential function, o, and two mutually orthogonal stream functions, u and u*, to describe the flow. Problems are formulated in an inverse space where the potential function and the two stream functions are the independent variables, and the Cartesian coordinates x, y, and z are the dependent variables. The boundaries of the problem in the physical space, including the free surface, have known positions in the inverse space, so trial and error adjustments to the positions of the boundaries are unnecessary. …

Bulletin No 3867 - Water For Agriculture. Clearing Cloudy Or Coloured Water, N. E. Platell

Bulletins - 3000 - 3999

THE suspended material in most water supplies is generally clay, although sometimes organic matter and materials precipitated from solution, such as hydrated iron oxides, may be present. Coloured waters are those waters that are still coloured, due to dissolved coloured matter, after suspended material has been removed. Some coloured waters such as those found in swampy areas may be entirely free of suspended material.

The amount of clay or colour present is mainly of concern where the water is used for household purposes. Only rarely is the clay or colour present in such quantities that the water is undrinkable for …

Location Of Solution Channels And Sinkholes At Dam Sites And Backwater Areas By Seismic Methods: Part Ii, Vincent P. Drnevich, D. Raghu

KWRRI Research Reports

Four seismic field methods and a laboratory method are used to determine shear wave propagation velocities and shear moduli for two sites. The four seismic methods are: standard seismic refraction survey, down hole shooting refraction survey, transient Rayleigh wave survey, and crosshole shooting survey. A torsional resonant column apparatus was used for the laboratory tests. The cross hole shooting method gave the best results because direct measurements were made. Criteria for using this method are given. Methods which measure compression wave velocity give inconsistent results because the conversion to shear wave velocity is very sensitive to Poisson's ratio. Laboratory tests …

Location Of Solution Channels And Sinkholes At Dam Sites And Backwater Areas By Seismic Methods: Part I, Vincent P. Drnevich, S. R. Smith, E. P. Cleveland

KWRRI Research Reports

The basic concepts associated with the sledge hammer seismic refraction survey are reviewed and a modified version called down hole shooting is discussed. The latter method has distinct advantages for rock surface profiling. These include: calibration at the end points of the survey, measurement of vertical wave propagation velocities directly, and having a refracted wave ray path for almost the entire survey length.

The down hole shooting seismic refraction survey has been simulated with the digital computer. The method can handle any shaped rock surface profile and generates corresponding travel time curves for the forward and reverse profile surveys. This …
