Transpiration Cooling Of A Heat Generating Porous Plate, M. K. A. Hameed

Masters Theses

"This investigation is a continuation of a thesis by T. S. Purewal. Several of the simplifying assumptions made by the above author are either ignored or the justifiability of such assumptions is probed into in order to obtain a more rigorous solution. Effects of the assorted grain size, non-Newtonian cooling, direction of coolant flow, thickness of the porous heat generating plate, specific heat of the coolant, and compressibility of the coolant are investigated in this thesis. Variation of maximum temperature of both coolant and the solid material for different types of heat source distribution are also studied.

As the grain …

A Study Of Segregation In Cast Aluminum-Uranium Alloys, B. L. Bramfitt

Masters Theses

"This investigation involves a photomicrographic study of the segregation resulting from the eutectic solidification characteristics of aluminum-uranium alloys, ranging from 5 to 30 weight percent uranium. The segregation can occur in either of two manners; the first, due to the gravitational forces acting upon the growing particles which nucleate in the melt and the second, due to the mode and rate of heat transfer through the material. It was found that segregation occurred only as the result of the latter factor due to the small volume of the ingot and the rapid rate of heat transfer. The segregation was measured …

A Weight Loss Technique For The Determination Of Phase Boundaries, Robert Lee Benner

Masters Theses

"An apparatus has been designed and constructed that would continuously record the weight loss of a sample in a flowing inert atmosphere, at a constant temperature.

A technique has been developed to determine the phase boundaries of a binary phase diagram.

Alloys of the magnesium-nickel, cadmium-antimony, copper-cadmium, copper-zinc, and magnesium-zirconium systems were subjected to investigation to verify the operation and resolve a number of limitations of the equipment.

These investigations disclosed that the apparatus gave the best results with alloys having vapor pressures in the range between 1 and 35 millimeters of mercury"--Abstract, page 2.

Fm 55-8, Transportation Intelligence, 1961, Robert Bolin , Depositor

United States Department of Defense Military Intelligence

In 1961, American military intelligence was decentralized. The Army was responsible for all intelligence concerning foreign armed forces. Within the Army, the technical services – Transportation Corps, Signal Corps, Ordnance Corps, etc. – were responsible for intelligence concerning analogous organization in foreign organizations. The Transportation Corps was responsible for intelligence concerning foreign transportation equipment and services. Since there was no centralized American military intelligence organization, the Transportation Corps was tasked with supplying intelligence concerning foreign road and rail networks and waterways as well as ports and landing beaches and airfields.

This manual defines transportation intelligence and prescribes Army doctrine concerning …

A Machine-Laid Surmountable Bituminous Concrete Median, Robert L. Florence

Kentucky Transportation Center Research Report

On August 28, 1961, personnel of the Research Division were requested to observe a demonstration of a newly developed Etnyre Median Paver. The demonstration was given at the Lehman-Roberts Company plant in Lexington, and was arranged primarily for the benefit of the paving contractor working on Euclid Avenue in Lexington. The paving contract called for the construction of a surmountable bituminous concrete median which, to our understanding, is the first instance for construction of that type to be machine-laid. Some doubts arose during the demonstration as to the ability of the machine to hold alignment and to give adequate compaction. …

Water Requirements For Waterfowl Areas Near The Great Salt Lake Parts V-Vi, J. E. Christainsen, Ming Chang Tsai, D. K. Kaushik, J. B. Law, J. W. Teeter

Reports

This report reviews activities on this project since the Progress Report, Part IV, June 1961.

The summer of 1961 has been one of the driest on record for Ogden Bay and Howard Slough Refuge. The extreme shortage of irrigation water has resulted in very little flow in the Howard Slough which originates from return flow. The available water from the Weber River for the Ogden Bay Refuge was also the lowest on record. The scarcity of water at these two refuges has resulted in increased salinity.

Most of the routine work on the project during the summer was done by …

Performance Of A Reinforced Concrete Pipe Culvert With Standard And B1 High Fill Bedding Under Rock Embankment, Ralph R. Taylor

Kentucky Transportation Center Research Report

In co-operation with the Bureau of Public Roads, a number of reinforced pipe culvert installations in a number of states have been selected to evaluate the effectiveness of the design and construction criteria. One particular pipe has been chosen for this special study because of its installation conditions. This pipe is located on I 75-6 (5) 123 in Scott County at Station 37 + 50, US460, SW Ramp, and has been constructed using both type beddings that are specified in the 1956 edition of the Kentucky Department of Highways Standard Specifications for Road and Bridge Construction and amendments thereto. Observation …

Investigation Of The Platinum-Rich Portion Of The Platinum-Tantalum Phase Diagram, Bob Dean Browning

Theses and Dissertations

The Pt-Ta binary system was investigated at two isotherms;1000°C and 1500°C, and at eleven alloy compositions in the range of 50 to 100 atomic percent platinum. The alloys were examined by x-ray diffraction and metallography. Three intermetallic compounds, Pt₂Ta, Pt₃Ta, and Pt₄Ta were found to exist in this composition range. The Pt₄Ta intermetallic appeared only at the 1500°C isotherm. Platinum dissolved tantalum substitutionally to 90 atomic percent at 1500 °C and to approximately 80 atomic percent at 1000 °C.

Effect Of Elevated Temperature On Efficiency Of Corrosion Inhibitors, Walter Dzingala

Theses

An experimental program was set up to investigate the effect of temperature on the protection efficiency of various inhibitors of metal corrosion. Contrary to most studies, an appreciable amount of the work was done with the corrosive effect being determined on the metal specimens that were exposed first to the inhibitor, then to air at different temperature, and finally to the corrosive medium with no inhibitor present. The purpose being to determine whether the inhibitor treatment would provide a permanent protection for a metal surface or would it be necessary to furnish a continuous supply of the inhibitor to the …

Indiana Local Technical Assistance Program (LTAP) Publications

This bulletin, developed primarily for the highway engineer and the county road supervisor, describes the more important herbicide materials available for roadsides, their recommended use, and application methods. Information is also provided to help county road officials develop better weed and brush control programs for county road systems. The last part of the bulletin covers details of planning a county-wide weed and brush control program.

The Influence Of Water-Reducing Admixtures On The Curing Of Concrete, Wallace Don Budge

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The use of water-reducing admixtures in concrete has grown continuously since their introduction over 25 years ago, with a present estimated usage in the production of 25 million cubic yards of concrete annually in the United States alone. Opposition to anything added to concrete, other than cement, aggregates, and water, is gradually disappearing, and considerable recognition is being given to the value of using other ingredients.

The research contained in this study may be divided into two portions: tests to determine the rate of volume change of cement paste and compressive strength tests to indicate the effect of moist curing …

Soil Moisture As A Factor In Streamflow Forecasting For Logan River, Utah, Yu Kam Fok

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Purpose

Forecasting the annual water supply in an arid area by using the water content of snow on watersheds on some particular date, such as April 1, has become a very useful practice. Although these forecasts have given results of great practical value, they have sometimes been considerably in error. Seeking to minimize error, forecasters have incorporated various additional data such as temperature and antecedent rain to improve the relation between snow measurement and measured runoff.

Numerous methods have been suggested in the search for a reliable streamflow forecasting equation and various data have been used. Nearly all of the …
