The Relation Between Soil Characteristics, Water Movement And Nitrate Contamination Of Ground Water, Grant W. Thomas, Matthew Mcmahon

KWRRI Research Reports

Soils from several areas in Kentucky were placed in columns and leached with Ca(NO₃)₂. Subsoils high in iron oxide were found to retard the leaching of nitrate very significantly. In other soils, the nitrate moved through as fast as or slightly faster than the water.

Field application of nitrogen to corn was most efficient when done in the spring or summer near the time that the corn takes it up. The one exception to this was a red soil, where fall application of nitrogen resulted in little loss due to the retarding effect mentioned in the …

Accident And Economic Analyses Of Access Control On Several Bypasses, Kenneth R. Agent

Kentucky Transportation Center Research Report

In an effort to relieve congestion on urban streets, bypasses have been built to provide through traffic a route by which the downtown areas can be avoided.

In many cases, though, bypasses have created a serious accident potential because they were built with at-grade intersections and no access control. This leads to commercial developments along the bypass and congestion at major intersections. Bypasses were constructed in this manner because of the high initial cost involved in building a bypass with access control and grade-separated interchanges. There is, therefore, a need to determine if the accident cost savings, along with time …

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 …

Hydraulic And Sediment Transport Studies In Relation To River Sediment Control And Solid Waste Pollution And Economic Use Of The By-Products, Bruce R. Moore, Michael R. Short

KWRRI Research Reports

The distribution of sediments and conditions of transport were studied in the Kentucky, Big Sandy and Ohio Rivers. The sand and coal were in transport at different flow velocities for the rivers and the deposition of these sediments was a direct function of the flow conditions at a particular locality.

The flow conditions of transport of the sediments were studied in flumes as were the hydraulic conditions in model dredge holes to determine the feasibility of trapping sediment. The conditions of scour and fill were also established and compared with known conditions in a dredge hole in the Ohio River. …

Impact Of A Proposed Reservoir On Local Land Values, Philip Drucker, Charles R. Smith, Allen C. Turner

KWRRI Research Reports

This project was designed to study the impact of private preconstruction land acquisition in a Central Kentucky area in which a flood-control dam and reservoir impoundment is planned. The research design was built around use of anthropological concepts and research techniques. By these means it was possible to analyze the perceived values of land to traditionalist residents, among which social and economic security concepts are paramount. Recent land purchases, locally believed to have been made chiefly by "outsiders," (urbanites from nearby Louisville), at prices out of line in terms of local agricultural worth, has been extremely unsettling contributing to the …

High-Intensity Reflective Materials For Signs, Rolands L. Rizenbergs

Kentucky Transportation Center Research Report

The intuitive need for improved sign legibility has increased through the years as traffic volumes, speeds and roadway designs have advanced. Because of increased traffic volumes, low-beam headlight illumination at night has become more imperative. Signs are being located farther from the travelled lanes; higher speeds are requiring messages to be more legible at greater distances (for driver decision and response). Recent studies have indicated that even Engineering Grade (2200 and 3200 Series) Scotchlite or materials designated as Type I, Class A in S.P. No. 89-A, may be inadequate for some signing situations. Signs may be made larger and(or) incorporate …

Electrical Sensor Of Plane Coordinates, George S. Hurst, James E. Parks

Physics and Astronomy Faculty Patents

An inexpensive electrical sensor of plane coordinates employs juxtaposed sheets of conducting material having electrical equipotential lines extending across each sheet and arranged normal to each other. A probe upon touching each sheet at a selected intersection of the equipotential lines causes separate signals to be applied to one or more conventional information-indicating units.

Digital Computer Modeling Of Limestone Groundwater Systems, John Thrailkill, David P. Beiter

KWRRI Research Reports

Because limestone groundwater flows mainly In discrete openings, limestone aquifers are fundamentally different from aquifers In granular rocks. A digital computer program which simulates flow in a limestone aquifer as a pipe network was written and compared with the Sinkhole Plain aquifer of west-central Kentucky.

A reasonably good fit between observed parameters of the aquifer and those calculated were obtained under assumed conditions of both laminar and turbulent now In the aquifer. The Indicated gross permeablllty of the aquifer is 5600 melnzers with an assumed aquifer thickness of 100 feet. The location and discharge of springs along the streams bounding …

From Caveat Emptor To Strict Liability: A Review Of Products Liability In Florida, Richard C. Ausness

Law Faculty Scholarly Articles

Since the doctrine of caveat emptor gave way to a more enlightened response, the courts have struggled to place the law of products liability on a proper doctrinal foundation. Negligence, implied warranty, and strict liability have been used, but as yet no universally accepted theory has emerged. In light of this problem this article will trace the development of seller's liability in Florida. Special emphasis will be placed upon implied warranty; in addition, the relationship between existing Florida case law, strict liability under the Restatement of Torts and the warranty provisions of the Uniform Commercial Code will be examined.

Rosenbaum, Billy R. Prebble, Charles O. Dowell, John E. Sirles, Michael B. Hargrove, Clyde T. Bates, Kenneth G. Holbrook, Dennis H. Bianchi, John P. Breaden, Kenneth R. Harman

KWRRI Research Reports

The institutions responsible for water resources management in the United States have originated as political responses to major social issues. Each agency institutionalized a procedure for structuring and comparing alternatives in the formulation of its total program. Each agency originally sought to promote effective resolution of its social issue (flood control, development of arid lands, soil erosion, etc.), but more recent efforts have sought better coordination among agency practices through a common procedure largely derived from economic theory. Any procedure, however, varies in application with the interpretation and judgment of individual planners. Today, public pressures have brought political directives requiring …

Carbon And Nitrogen As Regulators Of Algal Growth In Treated Sewage, Edward G. Foree, Charles Reece Scroggin

KWRRI Research Reports

Continuous flow algal cultures were grown under three different growth conditions using secondary sewage treatment plant effluent as the growth medium. The only variable within each run was the hydraulic residence time. The concentrations of growth regulating nutrients were varied between the runs so comparisons of the algal mass, composition, nutrient uptake, and genera could be made. The importance of CO₂ availability for algal growth was also studied. A kinetic theory which based algal growth on cellular nutrient concentration was verified. The second phase of the study was a batch culture study in which the same growth medium was …

Degradation Of Limestone Aggregate During Construction, Robert C. Deen, Herbert F. Southgate

Kentucky Transportation Center Research Report

Twelve construction projects were sampled at the plant, from the spreader box, after spreading, and after compacting. Laboratory tests including gradation analysis, ball-mill wear tests, Atterberg limits, and specific gravity were performed to determine changes in gradations. Kentucky limestones are very hard, high quality aggregates, with no significant degradation characteristics under current construction practices. On a given project, the construction procedure did not cause any significant degradation. Amongst projects, variances can be significant; however, this is attributable to the variation in initial gradations on the different projects.

Noise Pollution And Abatement: A Review Of Literature, Kenneth R. Agent, Robert C. Deen

Kentucky Transportation Center Research Report

Complaints concerning traffic noise and possibly seismic vibrations emanating from highways would probably have been adjudicated on the basis of common law doctrines pertaining to "nuisances", "common enemy'', and ''power of relief" were it not for recent legislation and regulations directed toward protection of the total environment. In effect, "freedom from noise" has been added to the clean water, clean air, clean earth policies. Surely each of those policies are founded on public sentiment.

There have been a few instances where the Department has yielded relief because of traffic noise. Now safeguarding regulations seem inevitable.

In the past, this Division …

Survey Of Czechoslovak Laws Affecting East-West Trade, Stephen J. Vasek Jr.

Law Faculty Scholarly Articles

Between 1960 and 1967 all of the major codes of Czechoslovak laws were redrafted. The culminating work in the redrafting process was the New Economic Model (NEM) which became effective in January, 1967. Under the NEM, allocation of resources and trade decisions were to be made primarily on the basis of profitability. The key to the implementation of the profit motive was the new market price system, under which prices were eventually to be determined by supply and demand rather than set by administrative fiat. Bonuses were to be paid workers and managers based upon the profitability of their enterprise. …

Determination Of Trace Elements In Water Utilizaing Atomic Absorption Spectroscopy Measurement, Gary D. Christian, J. Preston Miles Iii, Ronald Sensmeier, Melvin Sensmeier, Loraine Craig, Lynn Phibrick, Sudarshan Lal

KWRRI Research Reports

A variety of flameless atomic absorption methods have been investigated for the possible determination of trace elements in water. The general applicability of each technique was determined and where applicable, procedures have been developed for the determination of trace elements in natural waters.

Metals were preconcentrated by electrodeposition on a wire. The metals were then atomized for atomic absorption measurement by resistive heating of the wire. As little as 0.01 part per million (ppm) of mercury could be determined in this way.

A mercury cold vapor cell was constructed in which the sample is treated with a reducing agent to …

Degradation Of Riparian Leaves And The Recycling Of Nutrients In A Stream Ecosystem, Louis A. Krumholz, Roger G. Lambert, Charles R. Liston, Harry H. Woodward

KWRRI Research Reports

Leaves collected at 4 stations in the upper 5 km of Doe Run, Meade County, Kentucky, indicated an annual accumulation within the stream of 354 g/m²/year (17,700 kg). Leaves of sycamore (23.6%), red oak (21.7%), sugar maple (9.7%), beech (9.6%), white oak (7.1%), and hickory (6.0%) trees were most abundant, and leaves from 14 other kinds made up the remaining 22.3%. About a third of the annual leaf fall occurred during the last half of October and about two-thirds in the last 3 months of the year.

Calorific equivalents for different kinds of leaves ranged from 3,789 cal/g …

Factors Regulating The Growth Of Algae In Continuous Culture In Diluted Secondary Sewage Treatment Plant Effluent And Subsequent Biodegradability, Edward G. Foree, Caroline P. Wade

KWRRI Research Reports

Heterogeneous algal cultures were grown in laboratory continuous culture in continuous flow, completely mixed chemostats in secondary sewage treatment plant effluent diluted to give an ammonia nitrogen concentration of 10 mg/1. Variables were lighting, pH, carbon dioxide availability, and hydraulic residence time.

Optimum growth occurred under pH 7.0, excess CO₂, and continuous lighting conditions. The availability of artificially supplied excess CO₂ greatly increased the mass (standing crop) at steady-state over that produced under otherwise identical conditions for all residence times studied. For the case of excess CO₂ availability, the nitrogen concentration in the algal cells regulated …

Sentencing: The Use Of Psychiatric Information And Presentence Reports, Rutheford B. Campbell Jr.

Law Faculty Scholarly Articles

It has become apparent that the two disciplines of law and psychiatry have a common "interface" in the field of criminal justice. Commentators generally agree that the administration of criminal justice is greatly aided by psychiatrists and psychiatric data. That is not to say, however, that the meeting of the disciplines has been without incident or misunderstanding. Problems have arisen because of divergent attitudes and goals of the professions. Some commentators say that the concerns of the two disciplines are not the same; others claim that much of the problem lies in the over-estimation of the certainty and reliability of …
