An Energy Accounting Evaluation Of Several Alternatives For Hydropower And Geothermal Development, J. Clair Batty, J. Paul Riley, William J. Grenney, David A. Bell

Reports

Alternative management strategies for hydropower and geothermal development are myriad. This study does not attempt to evaluate or even summarize the many schemes which are possible. In an era of plentiful natural resources, economic analysis procedures for selecting a particular alternative have been developed which traditionally have tended to optimize on the basis of capital and labor. The approach taken in this study is based on the notion of optimum deployment of finite resources. A legitimate question which this study has attempted to address is: Does the construction of large water management facilities, such as hydropower dams, which involve huge …

The Effects On Agriculture In Utah Of Water Transfers To Oil Shale Development, B. Delworth Gardner, Kenneth S. Lyon, Roger O. Tew

Reports

In Part I the institutional factors affecting water distribution in the Upper Colorado River Basin in general and specifically the Uintah Basin are presented. The historical development of the appropriation doctrine of water allocation is outlined and Utah water policy is examined. These institutional factors are analyzed in light of the prototype oil shale development in the Uintah Basin and potential impact on the area's agricultural sector. Oil shale water estimates are compared with Uintah Basin water availability and examined with regard to population projections and municipal water use. Lastly, Utah water policy and the appropriation doctrine are viewed as …

Highway Accidents At Bridges, Kenneth R. Agent, Robert C. Deen

Kentucky Transportation Center Research Report

Grade-separation structures (bridges) at interchanges, crossroads, over streams, railroads, etc., which are intended to provide greater convenience and safety, otherwise involve features which either obstruct the range of free travel or serve as containment barriers. The objective of this study was to identify those principal features of bridges and appurtenances which may be related to accident frequency and severity and to provide some further insights toward highway safety.

Effect Of Pavement Texture On Traffic Noise, Kenneth R. Agent, Charles V. Zegeer

Kentucky Transportation Center Research Report

Noise from highway vehicles emanates primarily from engine exhausts, tire-pavement interaction) gears, and rattles. Studies have shown that at high speeds tires become the dominant generators of noise. Measurements on different road surfaces have produced different noise-versus-speed relationships (1). This led to the road surface adjustment used in the noise prediction procedure developed in NCHRP Report 117 (2). This adjustment called for a 5 dBA reduction for smooth surfaces (very smooth, seal-coated asphalt pavement) and a 5 dBA increase for rough surfaces (rough asphalt pavement with voids 1/2 inch (12 mm) or larger in diameter and grooved concrete). …

Pedestrian Accidents In Kentucky, Charles V. Zegeer, Robert C. Deen

Kentucky Transportation Center Research Report

When a pedestrian is hit by a motor vehicle, he is usually injured or killed; there is no protective cushion to absorb the impact. The high concentration of pedestrians in urban areas, coupled with heavy vehicle traffic, often results in large numbers of pedestrian accidents. In rural areas, there are considerably fewer pedestrians but traffic speeds are higher and, therefore, accidents are more often fatal.

Pedestrian fatalities have increased in the United States from about 7,800 in 1960 to approximately 10,500 in 1973 (1). There are 120,000 pedestrian accidents each year. Total traffic accidents in the US number about …

Speed Reduction In School Zones, Charles V. Zegeer, James H. Havens, Robert C. Deen

Kentucky Transportation Center Research Report

The use of flashing beacons together with signing has become somewhat standard throughout the country to alert drivers to the presence of school children and to regulate vehicle speed in school zones. Yellow beacons, usually two flashing alternately, may be used with both warning signs and regulatory signs. The only regulatory signs related to school zones are speed-limit signs. Both hazard identification beacons and speed-limit sign beacons are intended to operate only during hours when the warning and speed regulations are in effect. The effectiveness of signs and flashing lights in reducing speeds in school zones has been questioned.

Bolted Connections In Cold-Formed Steel Structures, Randall L. Mosby, Wei-Wen Yu

CCFSS Library (1939 - present)

INTRODUCTION A. Purpose of Investigation. The design of bolted connections in cold-formed steel structures is based on the present AISI Specification for the Design of Cold-Formed Steel Structural Members. 1 Prior to the development of the design criteria, bolted connections were tested at University of Michigan 2 in the 1940's and then at Cornell University 3,4 in the 1950's. The present design provisions were developed primarily on the basis of the tests conducted by George Winter and his associates at Cornell University. Additional tests were recently made by Popowich 5 on multi-bolt connections and by Dhalla 6 on connections with …

Distributed Parameter Sensitivity Theory To Solve Certain Reliability Problems, Moses Nee Buernor Ayiku

Dissertations

It is well known that in actual control systems there are uncontrolled parameter changes caused by aging of elements, temperature, pressure and effects of externalmedium, among others, which may impair the performance ofthe system. Hence, there is the need to develop systems that weakly react to these parameter fluctuations. Sensitivity theory has been developed to study some of these problems. Most of the investigations in this area, however, deal with problems in continuous systems modeled by ordinary differential equations. Even the recent publications on sensitivity problems in distributed parameter control systems are largely concerned with systems modeled by first order …

Subcontracting By The Petrochemical Engineer-Constructor, Michael Peter Skurla

Theses

An analysis has been made of the methods used by a Petrochemical Engineer-Constructor, who has national labor agreements, in deciding if the construction phase of a project should be done by a subcontract method of construction or be accomplished on a direct hire basis. The petrochemical complex under discussion is considered to be in the $75 million range for the total installed cost including design, engineering, procurement, and construction.

The influence of subcontracting portions of the construction phase by the Engineer-Constructor is reviewed with its impact on: the client; project schedule and cost; local and national labor relations, because of …

Non-Standard Workweek Scheduling Technique Selection, John Alexander Oak

Theses

This thesis presents a description of non-standard work scheduling techniques and a comparison method which enables decision-makers to differentiate between available work-scheduling alternatives with the purpose in mind of selecting the most appropriate and suitable arrangement. The method developed calls for the decision-maker to follow a five-step sequential process to obtain final results. The ingredients necessary to achieve such final results are obtained in a manner similar to that demanded by decision-making-under-uncertainty conditions commonly followed in actual industrial settings.

Since the primary objective of business management is the achievement of a profit through the manipulation of available resources, initial sections …

Prediction And Correlation Of The Salt-Effect In Vapor-Liquid Equilibrium, Enrique M. Bekerman

Theses

The feasibility of developing a method of correlation and prediction, for mixtures of two solvents containing a dissolved salt has been studied. The procedure consisted of arriving at the interaction parameters for the three binary systems (solvent 1-solvent 2, solvent 1-salt, solvent 2-salt) and using these to calculate the ternary results. Attempts to generate interaction parameters for the solvent-salt binaries by means of the Wilson equation were unsuccessful, whereas, use of the NRTL equation resulted in a very good fit of the binary data.

In correlating the ternary results, it became necessary to redefine the liquid phase mole fractions and …

Reaction Kinetics For The Synthesis Of Benzyl Benzoate From Benzyl Chloride And The Triethylamine Salt Of Benzoic Acid, Michael A. Kolakowski

Theses

The reaction kinetics for the synthesis of benzyl benzoate from benzyl chloride and the triethylamine salt of benzoic acid has been studied over the temperature range of 70-105°C and a mole ratio of benzyl chloride to triethylamine of 0.5 - 10.0.

A reaction mechanism which is consistent with the experimental data has been derived. The experimental data was analyzed by means of the integral method of analysis. The temperature dependency of the reaction was determined from Arrhenius' Law and the activation energy was calculated to be 15,064 cal/g-mole. An empirical equation which explains the effects of the reactant mole ratio …

The Technical Council of the Institute of Transportation Engineers (ITE) developed a program for school crossing protection. The intent of this thesis is to evaluate the ITE program within. the context of those programs developed by other agencies throughout the nation. Research materials were obtained from the appropriate Federal, state, local and other agencies through papers, articles, reports and correspondence. Upon the analysis of these sources, the ITE program was found to be deficient in several ways. Recommendations for modifying the program which are set forth herein include a revision of the ITE program including the school route map, clarification …

Bayesian Inquiry: An Approach To The Use Of Experts, King G. Yee

Dissertations and Theses

Subjective information is a valuable resource; however, decisionmakers often ignore it because of difficulties in eliciting it from assessors. This thesis is on Bayesian inquiry and it presents an approach to eliciting subjective information from assessors. Based on the concepts of cascaded inference and Bayesian statistics, the approach is designed to reveal to the decision-maker the way in which the assessor considers his options and the reasons he has for selecting particular alternatives. Unlike previous works on cascaded inferences, the approach here focuses on incoherency. Specifically, it employs the use of additional information to revise and check the estimates. The …

Determination Of Lead Content In Apical Tissue Following Root Canal Obturation With Sargenti's Formula, G. Merle Hickok

Loma Linda University Electronic Theses, Dissertations & Projects

Four Stump-tail monkeys were used to help determine if the lead in Sargenti's formula diffuses out into the apical tissue while confined entirely within the root canal. In each animal two teeth were filled with Sargenti's formula 1-2 millimeters short of the radiographic apex, and two teeth were filled with gutta percha and Proco-Sol sealer for controls, making a total sample size of sixteen. The time ranged from 48 hours to 120 days. Lead analysis using the spectrophotometric method showed a higher lead content in the teeth filled with Sargenti's formula than with the gutta percha controls.

Assessment Of Possible Carcinogenic Hazards Created In Surrounding Ecosystems By Oil Shale Developments, Gerald L. Dassler

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

One of the purposes of an environmental assessment is to foresee potential problems created by the introduction of contaminants into an ecosystem and to suggest appropriate control devices to mitigate the effects of such inputs. In the case of the oil shale industry, very little is known about the potential hazards, especially those related to the emission of organic compounds with carcinogenic potency. The hazards will probably be due to chronic exposures to the emitted compounds and the effects of such exposures are likely to take years to manifest themselves, as is the case with many carcinogenic substances. A precise …

Microbial Bioassay Techniques For Assessing Acid Mine Spoil Amendments For Revegetation, Michael A. Anderson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The revegetation of sterile acid mine spoils is a costly and lengthy process due to the many factors (pH, toxic materials, low nutrients, poor soil structure, temperature, moisture, length of growing season, etc.) which impede the establishment of stable plant communities. A microbial bioassay technique applied to soil systems has been developed to allow a rapid (four weeks) and integrated (with respect to nutrients and toxicants) determination of the best amendments for stabilizing mine spoils by revegetation. Using mine spoil from the Blackbird Mine, Cobalt (near Salmon), Idaho, various comb illations of nitrogen, phosphorus, chelators, trace elements, potassium, manure and …

Effects Of Heavy Metals (Cadmium, Copper, And Mercury) On Reproduction, Growth, And Survival Of Brine Shrimp (Artemia Salina) From The Great Salt Lake, Karl A. Gebhardt

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The purpose of this paper is to report findings concerning the effects of cadmium, copper, and mercury on the brine shrimp Artemia Salina, of the Great Salt Lake. Metal toxicity was observed in relation to acute susceptibility, growth, reproduction, and hatching of the brine shrimp.

Heavy metal concentrations such as cadmium, copper, and mercury are known to be considerably higher in the Great Salt Lake than those in both freshwater and seawater. No published study has been concerned with heavy metal effects on organisms in salinities greater than seawater (35 grams per liter total dissolved solids). The experiments reported …

A Rationale For Furrow Irrigation System Design And Management, Safa Noori Hamad

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Mathematical and computerized models are developed to design and optimize furrow irrigation systems. The optimization process starts with land grading design, if any is needed, followed by a prediction of maximum non-erosive furrow stream size allowed on a given soil and the associated furrow-advance function. An average depth of application per irrigation is then assumed from which the wetting pattern along the furrow and the amounts of runoff water are predicted. A design of an Irrigation Runoff Recovery System, IRRS, is then executed, if desired, and system cost is determined. Using the predicted wetting pattern and the appropriate Crop Production …

A Survey Of Use Of Left-Turn-On-Red, Kenneth R. Agent

Kentucky Transportation Center Research Report

The objectives of this survey were to determine the extent that a left turn on a red traffic signal (LTOR) has been used across the country and to learn how effective it has been. Responses were received from 43 of the 55 cities surveyed. Of the cities responding, 22 have either had past experience with LTOR or have recently enacted an ordinance which will allow LTOR in the future. Most LTOR laws limit its use to intersections of two one-way streets. A much higher percentage of cities in the western United States have laws permitting LTOR than cities in the …

Evaluation Of Thermoplastic Pavement-Striping Materials (Louisville And Jefferson County), Jerry G. Pigman, Kenneth R. Agent

Kentucky Transportation Center Research Report

Approximately 1,406,100 linear feet (428,579 m) of hot-sprayed thermoplastic stripe was applied to roadways in Louisville and Jefferson County in the summer of 1973. Visual observations of appearance, durability, and night visibility were conducted according to ASTM D 713-69, the standard method for conducting road service tests on traffic paint. Attempts to conduct photometer measurements of the thermoplastic striping were unsuccessful. Visual observations made during rainy, nighttime conditions were also unsuccessful because very little difference was noticeable among the various sections.

The evaluation showed that the thermoplastic stripes performed considerably better on bituminous concrete pavements than on portland cement concrete …

The Socioeconomic Impact Of The Mountain Parkway And Ky 15, Joseph T. Farmer

Kentucky Transportation Center Research Report

A study of socioeconomic variables in a nine-county region in Eastern Kentucky was undertaken to determine whether significant growth had occurred since the opening of the Mountain Parkway and reconstruction of KY 15. It was hypothesized that these roads have acted as catalysts with available resources to promote a better quality of life.

Study revealed that, while income levels and business sales have enjoyed substantial increases, overall quality of life is still poor. Educational facilities are inadequate; economic diversification in business types is limited; coal is still the main stimulant for income and employment. However, outmigration of persons from the …

Intermetallic Reactions In Vacuum-Deposited Nickel And Gold Films On (111) Silicon Single Crystals, K. H. Yoon, Gordon Lewis, L. L. Levenson

Materials Science and Engineering Faculty Research & Creative Works

Pure nickel and gold thin films were vacuum-deposited on (111) silicon single crystals. When Ni/Au/Si or Au/Ni/Si samples were heated to about 550° in situ, hexagonal or deformed hexagonal shaped crystallites were formed on the silicon substrates. The composition of these crystallites was determined by using x-ray diffraction, scanning electron microscopy and scanning Auger microprobe methods. The crystallites were identified as NiSi2. The crystal-lites on the (111) silicon plane parallel to the surface appeared as regular hexagons while the inclined crystal-lites resembled trapezia. The results of Auger spectra and in-depth composition profiles for Ni, Au, and Si showed that the …
