Developing A State Water Plan Utah's Water Resources--Problems And Needs--A Challenge, Utah Water Research Laboratory

Reports

Of all the natural resources with which Utah has been endowed none is more vital to the social and economic well-being of the people than it water resource. We cannot manufacture water. We have found no acceptable substitute. Not one more drop of water is available for our use today than was available to the pioneers. Yet water uses and water demands have multiplied over the years. Since we can do little to change nature's water allotment to Utah we must learn how to utilize our existing supplies more judiciously. This means devoting increasingly more attention to problems of water …

A Simplified Method Of Estimating Drilling And Blasting Costs Of A Highway Through-Cut Excavation In Rock, Donald J. Roberts

Masters Theses

"The development of cost estimating methods has been the most neglected phase of highway engineering. Overlooked in particular has been the development of an easily understood and easily applied method of estimating the costs of the drilling and blasting operations involved in a highway through-cut excavation in rock.

This investigation developed such a method by adapting and applying recent developments in the blasting planning field. The study was limited to small diameter blastholes and excavations in lifts of less than thirty feet. Normal efficient construction practices were presumed.

It was found from the investigation that the blast geometry and, subsequently, …

Investigation Of Stresses And Deflections In An Inclined Beam., Jayant Chhaganlal Soni

Masters Theses

"In this thesis an investigation has been made of the effect of inclination on strains and deflections in an inclined rectangular steel beam. To compute the strains and deflections Newmark's Numerical Procedure has been used. An experiment has been carried out on a rectangular steel beam for four different load increments and eight different inclinations. To compare the experimental and analytical data, graphs have been drawn for the experimental and analytical quantities of strains and deflections for all the four load increments and eight different angles of inclination. Results of the investigation indicate that the strains and deflections at inclinations …

An Analysis Of Traffic Accidents On County Roads, D. F. Petty, H. L. Michael

Indiana Local Technical Assistance Program (LTAP) Publications

The purpose of this research was to investigate the causes of and determine possible remedies for the rising number of county road accidents in Indiana. County road accidents were defined for the purpose of this study as all traffic accidents occurring on roads which are administered by the County Commissioners in Indiana except accidents occurring at intersections of county roads with state highways. These latter accidents are normally charged to state highways. The information used in this research was obtained from accident records. The best available source of this type of information, the accident reports which are filed at the …

County Subdivision Control: Model Ordinance With Discussion, William Joseph Head

Indiana Local Technical Assistance Program (LTAP) Publications

The purpose of this manual is to impress upon the reader the urgent need for sound planning and to show what tools are available to facilitate the job of planning and (2) to provide a rough framework, a "model subdivision ordinance," around which a county can build a subdivision ordinance tailored to its particular needs and circumstances.

It must be emphasized that the values appearing in this manual are only typical minimal values. The model ordinance is quite general—any county wishing to adopt this ordinance would be obliged to initiate a study to determine to what extent the model ordinance …

Crystal Habit Modification Of Sodium Chlorate, Michael R. Keegan

Bachelors Theses and Reports, 1928 - 1970

All single crystals have a particular habit or morphology. The crystal habit refers to the relative degree of development of crystallographic planes into surfaces which make up the external appearance of the single crystal.

In this paper, NaClO3 is used as a parent crystal. Its simple cubic habit is modified to tetrahedral by the use of impurities of SO4=, S2O3=, Cr2O7=, and NO3-. The degree of habit change is studied as a function of impurity concentration and temperature. The problem and phenomena are explained in terms of surface chemistry and thermodynamics.

Physico-Chemical Principles Of Sixteenth Century Metallurgy, Robert E. Johnson

Bachelors Theses and Reports, 1928 - 1970

Following a review of sixteenth century metallurgical literature and a discussion of Gibbs free energy, this thesis discusses thermodynamic considerations of galena (PbS) reduction by iron from a lead assay of this period. The importance of fluxes in this assay is emphasized. The discussion covers both equilibrium and non-equilibrium conditions at 1100 degrees Celsius. Possible substitutes for iron are also covered.

Information from twenty-one small controlled lead assays is correlated with the thermodynamic discussion to determine the purpose of each constituent in the assay.

The Beneficiation Of Titaniferous-Magnetite Sands, Ronald Lloyd Nordwick

Bachelors Theses and Reports, 1928 - 1970

The purpose of this investigation of beneficiation methods is to develop and study possible economic methods for recovering an iron-titanium concentrate of sufficient purity to meet metallurgical requirements for subsequent direct reduction to pig iron and a high titanium slag.

Stress-Corrosion Cracking Of Brass, Paul A. Fossey

Bachelors Theses and Reports, 1928 - 1970

the mechanism of stress-corrosion cracking of brass has been sought for many years. Investigators have proposed many mechanisms, but each of these mechanisms has always had several drawbacks. This paper presents an account of experimental work done in the laboratory on this subject and compares it to the work of previous investigations. It evaluates the mechanisms presented by investigators and shows the failures of these mechanisms. A theory of Nitrogen Embrittlement is presented and an evaluation of this theory with experimental work follows.

Experimental Arc Furnace Smelting Of Titaniferous Iron Sands From The Northern Oregon Coast, Allan P. Herring

Bachelors Theses and Reports, 1928 - 1970

This investigation is an attempt to experimentally smelt titaniferous iron sands from the Northern Oregon Coast in a laboratory arc furnace.

The Effect Of Ph Upon Chelation Reactions In Montmorillonite Clays, Joseph Michael Keane

Bachelors Theses and Reports, 1928 - 1970

The purpose of this thesis is to investigate several chelation reactions and determine the effect of variable pH upon these reactions.

An Investigation Of The Sintering Of Iron-Wire Compacts, George L. Vivian

Bachelors Theses and Reports, 1928 - 1970

A study of the sintering of iron has been made by observing the rate of bonding of iron wires wound on iron spools. The specimens were sintered at a constant temperature of 850c in vacuum furnaces capable of producing pressures of 10-5 to 10-4 mm of mercury, and the growth of the bond between wires was observed as a function of time.

It has been concluded that the volume-diffusion mechanism is strongly operating in the sintering of iron at 850c, but in an evacuated system, the evaporation-condensation mechanism also contributes to the sintering process.

Farm Water Storage : Circular Brick Reservoirs, R P. Harington

Journal of the Department of Agriculture, Western Australia, Series 4

A circular brick tank is a cheap and efficient water storage which can be easily built on any farm. The method described below by Kimberley Research Station manager R. P. Harington was used to build a swimming pool—storage on the station.

Flooding And Salt Problems In The Wheatbelt, Department Of Agriculture, Western Australia

Journal of the Department of Agriculture, Western Australia, Series 4

VALUABLE land has become salty in parts of the West Australian agricultural areas because most of the surrounding land has been cleared and developed for agriculture.

This salting of a small proportion of the land is part of the price paid for the development of agriculture in this State.

Drainage is not the answer to the wheatbelt flooding and salt land problems.

A more practical approach is to limit runoff from sloping land, and to make good use of salt-affected land by growing salt tolerant perennial pastures on it, says the Soils Division of the Department of Agriculture.

A Study Of The Electro-Chemical Injection Of Ca(Oh)₂ Into Pure Kaolin Clay, Sam Michael Savas Jr.

A NoKarb Georgia Kaolin Clay was treated by passing a preferential electrolyte solution of Ca(OH)₂ using direct current for a period of one and six days. The tests performed during this investigation included the following: (a) tri-axial tests, (b) atterberg limits, (c) pH determination, (d) moisture content change (from treatment), (e) visual settling of treated …

Study Of The Design Of Reinforcement For Prestressed Concrete And Blocks, Charles Robert Hoffman

Masters Theses

"This thesis is an analysis of the transverse tensile stress condition in an end block of a prestressed concrete beam. A stress analysis was made by photoelasticity and compared to the mathematical solutions and experimental solutions performed by others on concrete models. The photoelastic model was made from a piece of Columbia Resin, 39.

Whatever method is chosen to determine the stress condition, there is no exact code that can be established to fit the various type problems which arise"--Abstract, page 1.

Velocity Distribution Induced By Free Jet Impact On A Stilling Basin, Sedat Özkol

Masters Theses

"At present, the use of the free jet impacting on a stilling basin as an energy dissipator is not very common, as there is very little information available concerning this particular field. However, if conditions are favorable, this type of energy dissipator will be quite economical to construct.

In this paper it was found that the hydraulic behavior of the free jet impacting on a stilling basin can be determined to a degree which may be considered accurate for practical purposes. It was also shown that given the free jet velocity, the magnitudes of the velocities at the critical points …
