A Comparative Study Of The Chemical Composition Of Artificially Dried Hay To Obtain An Insight As To Its Nutritive Value, Charles F. Schalbe

Bachelors’ Theses

This work has been undertaken as a ·result of tests recently carried out at the Greene Brothers' Brook Hill Farm at Genesee Depot, Wisconsin. It was found that cows, when fed artificially dried hay, produce milk in quantities greatly in excess of that accountable from known differences in the hay. Moreover, the milk seemed to have a different flavor - similar to pasture produced milk.

The Effect Of Current Density On The Efficiency Of A Brass Cathode In Chromium Plating, Anton E. Budner

Bachelors’ Theses

That chromium could be electrodeposited from chromic acid baths, has been an accomplished fact for over 70 years. However, only in the past few years, has the mechanism of the process been sufficiently understood to permit chromium plating on a commercial basis. Because of the properties and advantages of this particular deposit, tremendous interest and activity has developed in this practically new field. Numerous patents have been granted, but relatively little specific scientific information has been published. Much work can yet be done towards the development of this field. It is the problem of this thesis to study the effect …

An Analysis Of Pecan Nut Shells, Marie I. Bond

Bachelors’ Theses

This thesis deals with the methods or analysis or pecan nut shells and an attempt to identify the extracted pigment.

At present nut shells are waste products. This makes their study interesting from a commercial standpoint. In view of the fact that very little work of this kind has been done, nut shell analysis offers interesting research problems as well as excellent practice in the technique or organic analysis.

Such great interest is now being taken in plant pigments that, a thorough investigation of the red pigment yielded by pecan nut shell would be an appreciated contribution to science.

A Study Of Various Metallic Electrodes In Potentiometric Titrations, Louie Boncyk

Bachelors’ Theses

The significance of ion concentrations has been the subject of many investigations during the last few years. The results obtained have demonstrated without question the unlimited possibilities existing for laboratory and industrial applications of ion concentration measurements. It has been shown in many instances biological activity, fermentation, and filtration are influenced to a large extent by variations in the H-ion concentration. In addition, the way is open for improved control and accuracy in the many neutralization problems encountered in the laboratory. The lack of suitable electrodes has greatly retarded the practical applications of H-ion measurements to plant industrial problems. The …

The Distillation Curves Of Several Liquid Binary Stystems Of Various Aliphatic Alcohols With Benzene And Toluene, Jack Philip Eigen

Bachelors’ Theses

The object of this thesis is to determine the distillation curves of several liquid binary systems and to locate any constant boiling mixture by means of graphical representation.

Such an investigation has a commercial aspect. A research of this kind is valuable to the paint industry, and also for any industry interested in preparing very pure liquids by distillation. The following investigation limits itself to a study of. boiling point curves of mixtures of various aliphatic alcohols with benzene or toluene. These systems are reputed to have a minimum boiling which would be very valuable in the paint industry as …

Experiments On The Effect Of Current Density Of The Porosity Of Chromium Plated Steel, William G. Hilger

Bachelors’ Theses

The application of chromium plating in industry has grown out of a series of experiments conducted in the past few years. However as early as 1854, research was carried on in this field, but it was only in the years 1920 - 1925, that the chromium plating industry became an actual fact. From then on it has progressed very rapidly. In the present day chromium is applied for two main purposes: (a) to produce a permanent and decorative effect and, (b) to prolong the life of mechanical parts subjected to unusual conditions of wear or temperature. The electrodeposition of chromium …

The Amount And Identification Of Amyl Alcohols In A Commercial Mixture Of Pentanols, M. Eugenia Eberhard

Bachelors’ Theses

Casing head gasoline obtained from natural gas yields five commercial products. One of these is a mixture of amyl alcohols. As treated by the Sharples Company, West Virginia, pentane is separated and treated with chlorine. Three chlorine derivatives are produced. These are treated with caustic soda and may f'orm eight possible amyl· aloohols~1 The products of the normal pentane, only, are the subject matter of this thesis.

Symmetric Functions, Mildred L. Roth

Bachelors’ Theses

If function of two or more quantities is not altered when any two of the quantities are interchanged, it is called a symmetric function. For example, the trinomial a²+ b²+ c² is a symmetric function of a, b, c, because if any two quantities, say a and b are interchanged, the expression is unaltered in value.

The Effect Of Soil Moisture On The Establishment Of Spruce Reproduction In British Columbia, Percy Munson Barr

Amebelodon Sinclairi Sp Nov., Erwin H. Barbour

Bulletin of the University of Nebraska State Museum (1924–2023)

Amebelodonts are so new and so rare that even fragmentary facts relative to the group seem worth publishing. The specimen under consideration is a mandibular tusk found on the farm of Mr. A. S. Keith, Freedom, Frontier County, Nebraska, on the Morrill Geological Expedition of 1928, and is numbered 1-17-7-28, S. and L., the collectors being Bertrand Schultz and John LeMar, both of the class of 1931, the University of Nebraska. The formation was Late Pliocene or Pleistocene.

On Polynomial Solutions Of A Class Of Linear Differential Equations Of The Second Order, W. C. Brenke

Department of Mathematics: Faculty Publications

Certain well known polynomials have a number of common properties. They arise as coefficients of tⁿ in the expansion of a generating function ; they may be obtained by means of orthogonalization of a set of functions xⁿg(x) when the function ρ(x) = g²(x) and the interval are properly chosen ; they may be regarded as polynomials which become orthogonal when multiplied by a proper factor g(x) ; they satisfy a certain type of difference equation ; they satisfy a certain type of differential equation. The results …

Revision Of The Jefferson City Formation In The Rolla Quadrangle, James Shelley Cullison

Masters Theses

"The geology of the Rolla quadrangle was mapped by Lee in 1912. At that time all the dolomitic strata above the Roubidoux and beneath the Carboniferous formations in this area were placed in the Jefferson City. A more detailed study of the stratigraphy of the whole Ozark region by Ulrich has shown that some of the strata which had been included in the Jefferson City formation on lithologic grounds are not equivalent to the dolomites in the type section at Jefferson City, Missouri"--Introduction, page [1].
