Heat Transfer To Fuel Oil In Viscous Flow-Characteristics Of A Fin-Type Heat Exchanger., Boyd R. Abbott Jr.
Heat Transfer To Fuel Oil In Viscous Flow-Characteristics Of A Fin-Type Heat Exchanger., Boyd R. Abbott Jr.
Electronic Theses and Dissertations
A unit was constructed for the study of film heat transfer coefficients of a heavy fuel oil in viscous or streamline flow. The heat exchanger was of the shell and tube type, having extended longitudinal steel fins welded to the tube. Auxiliary equipment consisted of an oil pump, oil storage reservoirs, piping, and means for measurement of temperatures and oil flow rates. The unit was operated both as a fin type heat exchanger with the oil in contact with the finned surfaces, and as a straight tube and shell exchanger with the oil on the tube side. Oil flow rates …

The Reaction Of Ethylcellulose With Fatty Acid And Its Application To The Varnish Industry : Ii. Ethylcellulose In Pencil Lacquers., Albert L. Kimmel
Electronic Theses and Dissertations
Ethylcellulose was refluxed with Stearic, Oleic, Linseed Fatty acids, and a neutral Mineral Oil in the presence of a solvent. The products recovered were analyzed to determine if any possible reaction had taken place. Conditions for the reaction were carried out so that the temperatures obtained could be in the near range of varnish cooking, that is between 375 and 500°C. The I solvents used were diethylbenzene, boiling point 180oC and tetralin, boiling point 208oC. In each case approximate stoichiometric proportions of the fatty acids and ethylcellulose were used. These were refluxed to a sensible minimum viscosity of solution. The …

Much data was gained from "in-service training" received at the United States Public Health Service; Bureau of Industrial Hygiene, Bethesda, Maryland; University of Michigan; National Conference of Governmental Industrial …
A Study Of Some Of The Effects Of The War Upon Town And City Schools And School Personnel In South Dakota, James C. Schooler
A Study Of Some Of The Effects Of The War Upon Town And City Schools And School Personnel In South Dakota, James C. Schooler
Electronic Theses and Dissertations
The repercussions of war upon the 4-year accredited high schools of South Dakota during the period from October, 1941, to October 1943, have been numerous and intense. There have been considerable discussion concerning the effects of the war upon the schools, many articles have been written on the subject, and some surveys over the United States as a whole have been made. In SOuth Dakota it appears that there is a definite shortage of qualified educational instructors to teach the physical sciences and coach athletics. Many schools are operating with only one male faculty member, the superintendent. Some schools are …

Cassius M. Clay's True American., Albert D. Kirwan
Cassius M. Clay's True American., Albert D. Kirwan
Electronic Theses and Dissertations
Kentucky slavery was attacked during the summer months of 1845 from within by one of the state's native sons. Cassius M. Clay, son of a Madison County slaveholder, began the publication of The True American, an abolition paper, on June 3, of that year. He caught the tide of slavery controversy in one of its numerous periods of flux. At that time opinion on the slavery question was not solidified anywhere in the country. Since 1831 most of the opposition to the "peculiar institution" was centered in the states north of the Mason-Dixon Line. but even in that vast region, …

A Study Of German-Austrian Refugees In Louisville, Kentucky., Lina K. Wolff
Electronic Theses and Dissertations
This paper will deal with the adjustment of refugees in an American middle-sized city, Louisville, Kentucky. It will attempt to touch the background and past of the group, but it will be pointed to a question which indeed is vital to each refugee: What does he make of his life after immigration? Can what was in origin compulsory, become constructive for the future? Will America for him be more than a haven of refuge after a harassing persecution - will it be a home for him and his children? And the answer to these questions is inextricably tied up with …
The Development Of Ethyl Cellulose Lacquers For Automotive Use : An Ethyl Cellulose Lacquer For Coating Plastics., Robert Carlton Krueger
The Development Of Ethyl Cellulose Lacquers For Automotive Use : An Ethyl Cellulose Lacquer For Coating Plastics., Robert Carlton Krueger
Electronic Theses and Dissertations
There have been developed various colored ethyl cellulose lacquers that compare favorably with standard nitrocellulose lacquers in physical tests. Ultra violet light caused rather pronounced darkening of the lighter colors such as white and light yellow, probably because of the use of high amounts of phenolic resin. Also because of the presence of relatively large amounts of phenolic resin, the cost was somewhat higher than a comparable nitrocellulose lacquer. Suggestions for further work and improvement are included. An ethyl cellulose lacquer has also been developed to be applied by spray or brush to ethyl cellulose plastics with a minimum amount …
A Study Of The History Of Adult Elementary And Secondary Education And Possibilities For Future Service In Louisville, Kentucky., Flora L. Morris
A Study Of The History Of Adult Elementary And Secondary Education And Possibilities For Future Service In Louisville, Kentucky., Flora L. Morris
Electronic Theses and Dissertations
This study was inspired by a statement in the Louisville Public School Survey, 1943, in which Dr. George A. Works said, "Programs of adult education are exceedingly important in the modern community. The nature of modern life and the demands for continuous education and training suggest the need for school service in this area. Following the war, the demand will undoubtedly be very great. Louisville would do well to assign definite staff time for development of basic plans in this area." The writer was connected with the Works Progress Administration Adult Education Program as teacher from 1935 to 1937, and …

History And Development Of The Mental Hygiene Clinic Of Louisville, Kentucky., Mary-Elizabeth O'Brien
Electronic Theses and Dissertations
Interest in the field of Mental Hygiene and psychiatry has been stimulated by tensions of World War II. As in other communities there are mental hygiene and psychiatric facilities in Louisville. Kentucky. Since there is no available history compiled of this development such a study seems especially valuable at this time. How the community has gone about meeting the needs in this area of work in the past may be seen through such a study and may in turn prove a guide for future planning. The purpose of this dissertation is to trace the history and development of the Louisville …

A Follow-Up Study Of Thirty Eight Single Unmarried Mothers., Rose Migdal
Electronic Theses and Dissertations
This study of thirty eight unmarried mothers known to the Children's Agency of Louisville, Kentucky is an attempt to find out what happens to these girls after the agency has terminated its contact with them. The study is not concerned with the problem of unmarried motherhood as such, but rather with the individual girl who gives birth to a child out of wedlock. The study, further, is not concerned with causal factors, the why and wherefore but rather with those conditions which brought the girl to a social agency when she finds that either she cannot help herself or her …

Home Instruction For Physically Handicapped White Children In Louisville, Kentucky 1939-1940 To 1943-1944, Inclusive., Caroline Finzer Gray
Electronic Theses and Dissertations
Eighty-four children have been enrolled in Home Instruction given by the Louisville Public Schools, during the past five years, 1939-1940 to 1943-1944, inclusive. Home Instruction is given only to those children who cannot attend school, due to various physical handicaps. The writer feels that it will be profitable to examine the data collected concerning the eighty-four pupils, not only for the guidance of those intimately concerned with the Louisville program, but also for the information of similar workers in other cities and of the large numbers of lay people whose chief interest is due to their feeling that "the physically …

Convalescent Care In Louisville, Kentucky., Grace B. Caswell
Electronic Theses and Dissertations
This study is undertaken to survey and evaluate the adequacy of convalescent facilities available for indigent persons who have been under the care of the surgical service at the Louisville General Hospital. The adequacy of convalescent care will be measured first, in relation to its scope, second, in relation to its help to the patients, and third, in its interaction with other community agencies. The study is prompted by the recognition of the fact that convalescence is a sadly neglected field of medical care. Convalescence will be defined for the purposes of this study as the more or less gradual …
