Effects Of Season, Spacing And Intensity Of Seeding On Emergence And Survival Of Four Wheatgrass Species In Central Utah, Edwin B. Abbott

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Rehabilitation of deteriorated and abused range lands is being accomplished with greater success each year by the aid of better methods of seeding which include seedbed preparation, intensities of seeding, implements for planting and improved methods of eliminating competition. Much more information is needed, however, in order to recommend suitable methods and species for seeding various vegetation types and sones with reasonable reliability. Throughout the arid and semi-arid range lands, moisture is the principal factor limiting satisfactory seedling establishment. Special attention should therefore be given to more efficient utilization of the moisture supply. Closely related species or species with similar …

Viability Of Seed Produced By Annual Weeds And Winter Wheat Treated With Herbicides, J. Wayne Whitworth

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Large sums of money are spent annually for herbicides to control weeds in fall sown wheat. Many of these weeds are killed by such treatments while others survive and mature seed. Viability of seeds produced by weeds injured by systemic or growth regulator type herbicides has long been a matter of great interest, much speculation, and very little research. Data on this subject are needed in order to intelligently use chemicals for weed control.

The Testing Of Bacterial Strains Used In The Inoculation Of Legumes, Olga M. Goss

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

A part from their value as fodder plants, legumes such as peas, beans, clovers, vetches and lucerne play an important role in increasing soil fertility. Their value in the soil-enriching sphere has been recognised for centuries, but it is only comparatively recently that the reason for it has been fully understood.

Growth And Respiratory Studies Of Saccaromyces Cerevisiae In The Presence Of Selenium, Robert M. Pengra

Electronic Theses and Dissertations

The occurrence of selenium in certain soils of the United States and its detrimental effect upon livestock pastured on or fed forage from these areas has been well established. Selenium poisoning will not be reviewed here as several excellent reviews have been published (1, 2, 3). Studies on the metabolism of selenium by Sac-charomyces cerevisiae have been reported by Potter and Elvehjem (4), Lardy and Moxon (5), and Fels and Cheldelin (6, 7, 8). An attempt has been made in this thesis to repeat and enlarge on some of these studies. While this investigation may contribute information on the selenium …

Studies On The Respiratory System Of The Poky Strain Of Neurospora, Alfred Tissieres, Herschel Mitchell, Francis A. Haskins

Department of Agronomy and Horticulture: Faculty Publications

It was shown recently that the poky strain of Neurospora accumulates large amounts of cytochrome c, but is deficient in cytochromes a and b and thus in cytochrome oxidase and succinic acid oxidase activities (1). These findings, which suggest that respiration in poky does not utilize the cytochrome system, led to a study of the respiratory system of poky compared with that of wild type. The experiments reported here are concerned with the effects of the inhibitors cyanide and azide on the respiration of intact mycelium of poky and wild type, the oxygen uptake of cell-free extracts in the …

An Investigation Concerning The Incidence And Pathogenicity Of Pentatrichomonas Gallinarum And Its Relationship To Histomonas Meleagridis In Turkeys In Utah, Ross S. Hadfield

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Turkey raising has become big business. During the period 1942 to 1946, the average annual return in Utah amounted to about nine and one-half million dollars (4). This amount would have been increased considerably if the death loss among poults had been lower. As an example, using the percentage of mortality given by Miner (9, p. 5), it is estimated that the death-loss of turkeys in 1944 resulted in a loss of gross income by the farmers of Utah of more than four million dollars provided that the price the farmer received had remained the same.

The Texas Species Of Euthamia (Compositae), Lloyd H. Shinners

Field and Laboratory

Prefacing his "A Study of Euthamia" (Pittonia 5: 72-80, 1902), E. L. Greene says, "Altogether at variance with Solidago in habit and sufficiently well marked by several characters; much more nearly at agreement, habitally, with Gutierrezia, but necessarily separate from that group by its capillary rather than chaffy pappus, the genus is as definitely circumscribed as either Solidago or Gutierrezia, and as certain to obtain future recognition as either of them." With these remarks I fully concur.

The Influence Of Single, Two, And Three Stage Bleaching On The Opacity Of Deinked Stock, Wilbur Kite

Paper Engineering Senior Theses

"Bleaching may be defined as the alteration of coloring matter in such fashion as to cause it to reflect more true white, or the solubilizing of such coloring matter to make it possible to wash out the color substance, or both." (2) The most common method of bleaching is the oxidation of the coloring substance although reduction with ZnS₂O is sometimes used with ground-wood. This discussion will be limited to bleaching by means of oxidizing agents namely: chlorine and calcium hypochlorite.

The Saponification Of Esters, Robert Delong Sullivan

Bachelors’ Theses

The kinetics of chemical reactions has always been a very intriguing subject. It is the tool by which the mechanisms of chemical reactions are elucidated. Upon it partly rate the advisability of utilization of a particular reaction for industrial purposes. From it the field or catalysis has sprung. Chemical kinetics. is concerned with all branches of chemistry. Conversely, all branches of chemistry have an interest in it.

This thesis will attempt to do two things. First, the order, specific rate constant, and the energy of activation will be determined from the saponification of several esters. second, the introduction will cover, …

Use Of Dk Cheese Starter In Manufacture Of Commercial Cheddar Cheese, Carl Anthon Ernstrom

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Several months' curing time is needed to give cheddar cheese the desirable flavor demanded by the market. The exact length of time required for curing depends upon the flavor intensity desired, but the curing process is always costly and time-consuming.

The practice of making cheddar cheese from pasteurized milk is now common throughout the industry. Many progressive cheese factories are pasteurizing their milk and enjoying the consequent benefits from a higher quality product. Although pasteurization has eliminated many of the quality problems in cheesemaking, it has resulted in even slower curing cheese.

Much of the cheese research now being carried …

The Affect Of Indole-3-Acetic Acid On The Fission Rate Of Paramecium Caudatum, Margherita L. Baker

Student Scholarship

This research report, authored by Margherita L. Baker in 1951, investigates the physiological effects of the plant growth hormone indole-3-acetic acid, also known as heteroauxin, on the fission rate of the protozoan Paramecium caudatum. The study is grounded in the hypothesis that if plant hormones can influence animal growth, it suggests a fundamental similarity in the growth mechanisms between the two kingdoms. The experimental procedure was divided into two distinct series to observe how varying environmental conditions and food availability influenced the hormonal impact. 

In the first series, paramecia were maintained in a nutrient-rich beef extract medium with an abundant …

Actinomycetes Of Virgin Utah Soils With Special Reference To Antagonisms, Paul H. Krumperman

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The importance of actinomycetes in the soils was generally overlooked until about 1913. The investigators Hiltner and Stormer and Beijerinck began systemtaic study of their occurrence and role in soil fertility. The work done by these men and others since 1913 has proved actinomycetes to occur abundantly in most soils of the world. This work done by these men and others since 1913 has proved actinomycetes to occur abundantly in most soils of the world. This work has also proved the function of these organisms to be that of decomposing highly resistant materials such as humus and complex polysaccharide compounds. …

A Survey Of The Microflora Obtained By Flushing The Normal Bovine Uterus, Johannah Jane Wulf

Electronic Theses and Dissertations

Since artificial insemination has become a reality and the potentialities of ova transfer are being investigated by several research workers, it seems reasonable to assume that some attention should be directed toward gathering information regarding the bacterial flora of the normal bovine uterus. Both artificial insemination and ova transfer require the insertion of foreign bodies or instruments into the uterus. When such instruments enter this organ, there is always the possibility of introducing various kinds of bacteria. Very little information is available regarding the pathogenicity of these bacteria in the bovine uterus. The possibility of abortion due to such pathogenic …

Salmonella And Paracolon Species Isolated From The Wild Brown Rat, Rattus Norvegicus, In The City Of Richmond, Virginia, John Miles Sharpley

Master's Theses

The importance of bacteria as a cause of serious intestinal diseases in man and. other animals has been recognized since the early days of the science of bacteriology. Of those forms usually associated with intestinal disturbances in man, the species considered most important are those belonging in the Salmonella group, the Paracolon group, and the Shigella group. Also, it has been known since the early part of this century that the conman rat serves as an important vector for the dissemination of infectious organisms. For example, standard textbooks list rats as primary vectors of enteric bacteria. However. there has been …
