The Effect Of Riboflavin, Nicotinic Acid, And Thiamine On The Lipolytic Action Of Pancreatic Lipase, John G. Georgatsos

Bachelors’ Theses

The writer became especially interested in vitamins and enzymes during the course in the chemistry of Nutrition. To a person that has not studied them close enough the enzymes and the vitamins would seem to be miracle substances rather than chemical entities governed by laws. It was during that period that I made up my mind to study the Interrelation existing between the enzymes and the vitamins when the time would come for me to write a thesis. For this reason it is my pleasure to express my deepest appreciation to Dr. John R. Koch, Director of the Chemistry Department …

The Content Of Pantothenic Acid, Folic Acid And Vitamin B12 Like-Activity In Alfalfa Hay Grown In Utah Soils Treated With Different Fertilizers, Buranaphoka Kashemsri

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Vitamins play an important role in the nutrition of man and animal. As early as 1897 Eijkman was able to demonstrate the symptoms of thiamine deficiency disease in birds. Since then, vitamins have been regarded as one of the most essential factors in nutrition. Only small quantities in the diet are necessary, yet lack of any of them will inhibit the growth and produce certain kinds of deficiency diseases.

Factors Affecting The California Quail Populations In Uintah County, Utah, R. Lynn Nielson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The California Quail is native to the coastal and semi-arid regions of California extending north into Oregon. Two subspecies are commonly recognized. the California Quail (Lophortyx californica brunnescens Ridgway), and the Valley Quail (Lophortyx californica californica Shaw). The two forms are very similar in coloration and habits and, for the purpose of this study, no effort is made to distinguish the two.

Some Effects Of Fluctuating And Falling Water Levels On Waterfowl Production, Kenneth E. Wolf

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

There are today many areas and types of water storage. The uses to which these are put are many, and the prospect for the future can only be that there will be an increase in the number of these reservoirs. These areas are usually operated with regard only for power production, irrigation, or storage, but there is a growing concern about the effects on wildlife which this type of operation may have. Fluctuating water levels, and falling water levels are not restricted to man-made impoundments tut are characteristic of many of then. Biologists have observed that these variations in water …

Kimberley Soils Need Phosphates, W. M. Nunn

Journal of the Department of Agriculture, Western Australia, Series 3

Research work carried out at the Kimberley Research Station on the Ord River, and on experimental plots throughout the East and West Kimberleys, indicates that the soils of the Kimberleys are quite as deficient in phosphorus as are the soils of our agricultural areas where superphosphate is essential to the growth of most crops.

This may come as a surprise to many people, for there has been a widespread tendency to assume that the Kimberleys soils, especially those of the Ord and Fitzroy valleys, are highly fertile.

The black earths of Queensland's Darling Downs produce most enviable yields of sorghum …

Soil Conservation In Western Australia, G. H. Burvill

Journal of the Department of Agriculture, Western Australia, Series 3

Soil is a farmer's basic asset. This issue of "The Journal of Agriculture" in a new form designed to provide still better service to the farming community, is an appropriate medium through which to remind the man on the land of what the soil means to him—and to the State. The farmer's duties to himself, his family and the State are summed up in the words "soil conservation" which is merely another way of saying "wise land use."

Studies On Derivatives Of 3-Ethylphenanthrene, Eugene R. Miller

Bachelors’ Theses

The following thesis was undertaken to study the derivatives of 3 etbyl-phenanthrene. The problem was undertaken to familiarize the author with polynuclear aromatic hydrocarbons and the various reactions and unit processes which are involved in the synthesis or these derivatives. It is hoped that the experience gained in pursuing the objective of this thesis will provide a background which may prove valuable in future work tor an advanced degree and ultimately help to secure a position in some phase of research work dealing with biological compounds containing the phenanthrene configuration in its nucleus.

The Synthesis Of 3-Ethyl-9-Acetylphenanthrene, Elizabeth R. Bender

Bachelors’ Theses

In 1929 , there was recognized a relatively small number of naturally occurring phenanthrene compounds as compared with those known today. These compounds include several groups of substances which are as strikingly similar in structure as they are different in their actions on the animal organism. For instance, the structure of the sterols and bile acids contain the perhydrocyclopentenophenanthrene ring system. Upon later research, it was found that the sex hormones and cardiac glycosides (heart poisons secreted by toads) have a structure very similar to this system. They are all derivatives of cyclopentenophenanthrene.

Faunal Studies Of The Lower Jefferson Limestones, James L. Eymann

Bachelors Theses and Reports, 1928 - 1970

The exact geologic age of the Jefferson limestone in Montana has not been definitely determined, other than it is probably of upper, but possibly in part of middle Devonian age. Although not of immediate or apparent economic importance, the determination of the exact age of the Jefferson limestone may be of much value in connection with the discoveries of large quantities of oil in Devonian strata in the northern Great Plains and, in particular, with the extensive deep drilling in northeastern Montana which is anticipated during the summer of 1951.

Electro-Galvanizing From A Purified Ammonium Sulphate Leach Of Anaconda Zinc Calcine, Phillip J. Mischkot Jr.

Bachelors Theses and Reports, 1928 - 1970

Ever since the introduction of metal products into our civilization, especially those of iron and steel, man has been confronted with the problems of corrosion prevention. As the agents which are conducive to cor­rosion cannot be completely eliminated, it has been necessary for man to develop processes and materials that will retard the degeneration of the metals that are so important to our industrialized world.

Faunal Studies Of The Sappington Sandstone Of Southwestern Montana, Howard E. Banta

Bachelors Theses and Reports, 1928 - 1970

The exact upper boundary of the Devonian of Mont­ana has long been a controversy, as is true of the Dev­onian-Mississippian contact in many other localities. In an effort to delimit the upper Devonian, various paleontologic studies have been made, more especially in the southwestern part of the state.

Application Of X-Ray Technique To The Detection Of Internal Insect Infestation Of Grain, Max Milner, Milford R. Lee, Robert Katz

Robert Katz Publications

During the course of a comprehensive investigation of methods for the determination of internal insect infestation in commercial wheat, radiographic techniques have been developed at this station which provide satisfactory delineation of internal infestation. We have applied these techniques to the observation of the growth of such insects as granary weevil, Sitophilus granaries L., and rice weevil, Sitophilus oryza L., from the hatching of the egg within the kernel through larval and pupal growth to emergence as a mature insect. Although considerable detail is always lost in the reproduction of radiographs during engraving and printing, the accompanying figures (1, …

The Effect Of Metals On Yeast Activity, Warren Joseph Chamberlain

Bachelors’ Theses

The writer, having been employed in the dry yeast research laboratory of one of this country's largest yeast concerns for the past three years, is very much interested in those factors which might affect the qualities of the final dry yeast product, and has therefore made the investigations presented in this paper.

Because of the numerous pieces of metallic equipment employed in the production of yeast, the possibility of metallic contamination in the final yeast product is considerable. Thus, the investigation presented in this paper was carried out in an effort to determine just what effect various concentrations of various …
