Electronic Theses and Dissertations

This thesis deals with the design and construction of rolled-fill earth dams with the standard methods of practice, taking the Hirakud Dam as the basis. The field operations of the investigation to obtain observational information and to secure samples for the laboratory testing include observation of rain gauge and river gauge readings, taking river water samples, digging test pits, drilling grout holes, opening drifts, digging borrow pits and conducting detailed topographical surveys. Laboratory tests are conducted on the samples and the results are plotted in graphs. Rainfall and run-off statistics are plotted in graphs. Observational information of geology is plotted …

A Thermometer Technique For The Determination Of Emissivities Of Finishes., N. P. Shah 1923-

Electronic Theses and Dissertations

Two thermometer techniques for the determination of emissivities of surface coatings are presented. One procedure involving the attainment of steady state hear transfer relations in coated thermometers placed through the wall of a duct at right angles to the direction of air flow was found to give consistent results. Another procedure based upon the rate of change of thermometer temperature was found to give consistent results only with excellent control of air conditions. The emissivities of a variety of paints, varnishes and lacquers were determined for temperature range 90⁰ F. to 140⁰ F. using silver and black coatings for standardization. …

I. Improved Ice Meltage In Ice Boxes; Ii. Temperature Control In Tents - Winter Phase., Robert Beaman Duggan

Electronic Theses and Dissertations

This thesis consists of two parts: Improved Ice Meltage in Ice Boxes; Temperature Control in Tents - Winter Phase. Improved ice meltage in the Progress refrigerator is discussed in the first part of the thesis. This portion of the work shows that satisfactory refrigerator temperatures and flat ice meltage could not be obtained simultaneously when using V-shaped ice racks, although they could be obtained separately; however, the basket-type chamber offers greater possibilities of obtaining proper temperatures and meltage characteristics. Series of tests are discussed and conclusions drawn from the results. In the second part of the thesis, a method of …

A Study Of The Effect Of Pigmentation On The Film Properties Of Ethocel : Part Ii. A Study Of The Effect Of Sun Light On The Color Of Pigments., Mansur Ahmad

Electronic Theses and Dissertations

The purpose of this investigation was to determine quantitatively the effect of pigmentation on the film properties of ethocel lacquer. This study was confined to the determination of tensile strength, percentage elongation at failure, softening and melting points of the films. Pigments were ground in the ethocel lacquer containing three parts ethocel, one part 276V-9 Dow resin and sixteen parts solvent by weight. Softening and melting points of the films were determined and were found to increase uniformly with increasing amounts of the pigments. The tensile strength of ethocel film with titanium dioxide as a pigment increased from 317 Kgm/Cm2 …

Semi-Micro Combustion, Solvent Extraction, And Oleic Acid Adsorption Of Synthetic Drying Oils : Part Ii., Isadore Nathan Cooperman

Electronic Theses and Dissertations

The rates of oxidation, solvent solubility, and oleic acid adsorption, of natural and synthetic drying oil films were studied by semi-micro analytical methods.

This thesis consists of three phases:

I. Ultimate analysis to determine the oxygen content of a film at specific time intervals.

II. Extraction of the films to determine their solvent solubility as a function of time.

III. Oleic acid adsorption to get a correlation of the structure of the film.

Seven materials were examined:

A. Glyceryl Trilinoleate

B. Pentaerythritol Tetralinoleate

C. Pentaerythritol Oleate

D. Pentaerythritol Oleic Acid Long Oil Alkyd

E. Dipentaerythritol Linoleate

F. Pentaerythritol Linoleate

Glyceryl …

Newspaper Matrix Backing Techniques., Robert Roscoe Childs

Electronic Theses and Dissertations

The problem of developing suitable materials and techniques for the elimination of hand backing of mats was undertaken. A thermosetting resin of the resorcinol type, ad-mixed with 15 to 25 per cent short-fiber asbestos, was applied to the mats both as a paste and in the form of a partially cured resin sheet. Its use was discontinued since its inherent insulating properties and warpage were found to be undesirable.

After experimenting with several other backing materials and methods, the following procedure was concluded to be feasible:

(1) Spraying sodium silicate solution upon a sheet of blotting paper.

(2) Pressing the …

Relative Volatility Of Esters In Ethyl Alcohol-Water-Ester System., Yi-Chung Chang

Electronic Theses and Dissertations

The relative volatillities of five branch-chained esters with respect to ethyl alcohol in mixtures of ethyl alcohol and water containing small amounts of esters were determined experimentally. The results could be used in the design of distillation columns for ethyl alcohol purification.

For alcohol concentrations of more than 50 mol per cent, the increase of relative volatility of the esters was inversely proportional to the alcohol concentration. For dilute concentrations of less than 30 mol per cent the increase in volatility was very rapid, and the rates of increase were different for different esters. No simple quantitative correlation was established …

A Study Of Diffusion In Distillation., Joseph G. Duffey

Electronic Theses and Dissertations

A study of the mass transfer phenomena in fractional distillation was made. Small scale single slot, single cap apparatus was used to obtain the necessary experimental data.

The mass transfer coefficient KgA was calculated using several combinations of liquid and vapor compositions in the menthanol - water system under static liquid conditions. The correlation showed that KgA held about constant over the entire range of concentrations.

The problem of bubble area was studied and reasonable estimations of area, bubble frequency, and time of rise were made. This information is to be incorporated into the calculation of the mass transfer coefficient …

Plywood Adhesive Development., Edward J. Dowd

Electronic Theses and Dissertations

This thesis is primarily a study of two-step plywood adhesives made with varying amounts of phenol, 1, 3, 5 xylenol, resorcin, and formaldehyde. Each resin was evaluated by using it as the adhesive in making plywood. The plywood was then tested for shear strength and wood failure after a four hour boil.

Procedures are given for making and testing various straight phenolic resins and resins modified with 1, 3, 5 xylenol or resorcin, or comibinations of both of these accelerating resins.

The straight phenolic resins gave boil-proof bonds, but the curing cycle was too long. Those phenolics modified with 1, …

A Study Of The Mechanical And Economical Problems Involved In Converting A Farm Tractor From Gasoline Fuel Type To A Liquified Petroleum Type, Dennis Leroy Moe

Electronic Theses and Dissertations

This publication treats of a subject which has received a very limited amount of study. A considerable number of liquified petroleum gas burning internal combustion engines have been sold to the public during the past few years with the purchasers having a very limited amount of knowledge and information as to their practibility and economy.

An Amplidyne Voltage Regulator, Junis Oliver Storry

Electronic Theses and Dissertations

Many electrical devices are given voltage ratings. Although the performance of a device may be considered satisfactory at some voltage other than rated, this performance may be quite different from that intended. Incandescent lamps, heating appliances, and electric motors are common devices, the performances of which can be checked easily at various voltages.

A Method Of Measuring The Quantity Of X-Radiation, J. Norman Cheadle

Electronic Theses and Dissertations

Experimentation at South Dakota State College to determine the mutations in plant life resulting from the exposure of the seeds to X-radiation, made it desirable to be able to measure the quantity of radiation to which the seeds were exposed. Seeds being used in these tests are sorghums, castor beans, sunflowers, and safflowers. The tests will require a group of successive plant generations over a period of years. The purpose of this paper is to present a method by which the quantity of X-radiation, in roentgen units, can be measured.
