Faunistic Survey Of A Limited Area In New Mexico, Louise Wilkinson, Hazel Fern Reeves

Biology ETDs

The subject of this thesis was suggested by Prof. A. O. Weese. It was chosen by the writers first because they were interested in the distribution and habits of animal life in New Mexico and second because they wished to learn more about classification and methods of classification of animal life in general.

It has been found that New Mexico does not afford so great a variety of animal life as compared with more moist regions but that it affords much more than a casual observation would indicate. Most of those which it affords are found in large numbers.

The Design And Construction Of A Power Transformer, James M. Johann, George P. Nugent

Bachelors’ Theses

Usually one coil of the transformer has many more turns of wire than the other, when the coil of few turns is the primary, the transformer takes a large current at a low potential and delivers a smaller current at high potential. This is called a step up transformer. When the coil of many turns is the primary the transformer takes small current at high potential and delivers greater current at lower potential. This type is called a step down transformer.

Some Aspects Of The Philosophy Of Joseph Conrad., Minnie Lee Dodd Hill 1886-1959

Electronic Theses and Dissertations

A man's philosophy is his view of life. And every man who has lived his life – not merely spent it – has a philosophy. The convictions which go to make up this philosophy are rooted in the sub-soil of his experience. This sub-soil may contain ingredients carried up to him from the past of his race, of his nation, of his ancestors. His insight into his environment is not merely the view of a detached individual. The sad and gloomy experiences of Conrad's parents (banished to Vologda for taking part in Polish rebellion 1862) probably started in his child …

Some Studies On The Effect Of Different Storage Temperatures Upon The Fat Constants And Acidity Of Print Creamery Butter, Arthur D. Lynch

Electronic Theses and Dissertations

The observation of butter under different storage temperatures is interesting because of its practical bearing upon the factory phase of the dairy industry. Admittedly butter must be stored. It is consumer steadily. It is produced in varying quantities. It is a perishable product. Economic conditions have created the butte store house whereby uneven supplies may be more evenly distributed. Under all practical storage conditions butter deteriorates. Chemical changes occur, more or less pronounced, injuring the quality and thereby affecting the market value. One of the chief constituents which under goes noticeable chemical change is the fat, which is over 80% …

The Individual And Society, Hagop B. Boghosian

Historical Dissertations & Theses

"...Among the animals, sociability predominates over solitude and individualism and I shall endeavor to prove that this is also true among human beings by tracing the relation to the individual to society: first, among primitive people; second, among ancient Greeks and then, among the modern nations, and in so doing I will show its application to education."

Simple Methods And Tables For Determining True Meridian, Howard Jones Teas

Bachelors Theses

"The ordinary methods of determining the true meridian by observation on either Polaris or the sun are so tedious to calculate that most surveyors and students dread making them. Observation on Polaris at either elongation or clumination sic require less calculation and are much simpler, but this simplicity is offset by the fact that they must be taken at an exact instant. If a cloud crosses the sky at the time, the surveyor has to wait until the next night. then again the observer must know the date, exact longitude and latitude and correct time for making the observation, and …

Concentration Of Ores By Flotation, John Gay Reilly, Frank Stillmann Elfred

Bachelors Theses

"Flotation is a new step in the separation of valuable minerals from gangue. This process has only been in commercial use for about six years. There has been several theories advances as to how the ore is concentrated, and the theory that is now usually accepted is that the oil covers or wets the sulphide mineral particle and does not the gangue; and this mineral particle, by means of induced aid is concentrated on the surface. The authors of this thesis have not attempted to explain the reason or reasons why minerals will float; but have accepted the theories advanced …

Chemical Control Work In The N. K. Fairbanks Factories, John Whittlesey Bodman

Professional Degree Theses

"We propose to discuss in this thesis the organization of the N. K. Fairbank Company, particularly with reference to the duties of the Chemical Division, Operating Department in this organization. From a broad viewpoint, we believe that the particular organization by with the N. K. Fairbank Company secures application of its chemical ability to manufacturing operations as well as to special problems, is characteristic of a widespread movement taking place for recognition of the chemical engineer in industry. This is particularly true in those industries where manufacturing operations are based primarily upon practical applications of chemical principles"--Abstract, page 1.

Descriptive Study Of The Petroleum Refinery At MinatitláN, GermáN GarcíA Lozano

Professional Degree Theses

"In order to reduce as much as possible the cost of transportation of the crude oil to the refinery, the city of Minatitlán of Minatitlán County in the State of Veracruz was chosen as the most proper place for establishing the refinery it being in the center of the only oil fields which at that time possessed the "Eagle Mexican Petroleum Co."--page 1.

The Goltra Process Of Concentrating Iron Ores As Developed At Waukon, Iowa, Ernest Wander

Professional Degree Theses

"The more or less impure iron bearing mineral occurs mixed with a very tenacious clay, in which are also found chert, cretaceous quartz pebbles, pockets of sand, masses of pebbles and sand cemented by hydrous iron oxide, (which in some cases partly replaces the silica) and several varieties of fossils, such as crinoids etc. The impurities mentioned are often an integral part of the ore particles, and are present in varying quantities thruout [sic] the deposit. But, besides the foreign matter which the eye can discern, the apparently pure mineral contains a varying percentage of silica and alumina, (as well …

Some Typical Bridges For Logging Railroad Construction, Frederick Hauenstein

Professional Degree Theses

"In some of the pine regions of the Ozark Mountains, a considerable portion of the country is rolling and rough, comprising a succession of hills and hollows. The most efficient method of logging such a tract is obtained by locating the logging road so as to secure a down grade haul for the logs, with consequent up grade return for the empty cars. This necessitates locating the main line of the railroad along the principal creek, and then laying spurs up the different tributary creeks as they are met. Such a procedure requires much crossing and re-crossing of creeks and …

Concentration Of A Joplin Slime By Flotation, Earl Joseph Weimer, Walter Harry Freudenberg

Bachelors Theses

"Concentration of the Joplin slimes by means of flotation is a subject receiving considerable attention at the present time, due to high price of zinc. These slimes are the accumulation of the finer particles of the ore during the milling process, and their zinc content is well worth considering. The practice in the past has been to sluice these slimes into the tailing pond, as no economical method of saving the zinc had been employed. The object of our experiment was to economically extract from these slimes by flotation, a product of sufficient zinc content to be of commercial value"--Introduction, …

Selective Concentration Of A Complex Ore By Flotation, Paul Frederick Pape, Ralph Dale

Bachelors Theses

"The problem of the Mining Engineer and Metallurgical Engineer who wishes to treat the slimes and fine sands of a complex ore is the recovery and separation of minerals so as to render a subsequent treatment of any mineral profitable. The minerals must be separated into groups which can be treated by different processes, because a combination of numerous minerals is extremely undesirable at the smelting plant. In a lead ore the presence of zinc often depletes its value to such an extent that it is unprofitable to treat it; likewise with other minerals and ores. Many systems of selective …

Practical Details Of Mine Surveying In Certain Mines Of Northern Mexico, Arturo C. Fernandez

Bachelors Theses

"The name of this thesis is suggestive of its character. The writer has endeavored to resent in a general way some of the most important details of mine surveying as he has found them in actual practice. For the sake of uniformity the engineering staff in which he worked prepared a set of instructions to be used by the engineers at the various mines. The methods and illustrations described in this paper have been adapted from these instructions and they afford a thorough foundation ready to receive the minor details best adapted to each particular mining district"--Foreword, page ii.
