Pheasant Reproduction And Survival As Related To Agricultural Fertilizer Use, Lawrence Francis Fredrickson Jan 1974

Pheasant Reproduction And Survival As Related To Agricultural Fertilizer Use, Lawrence Francis Fredrickson

Electronic Theses and Dissertations

Wing-clipped wild pheasants (Phasianus colchicus) were stocked in 1-acre and 0.5-acre pens having oat and bromegrass cover in 1972 and 1973 to test effects of fertilizer (Formulations: 34-0-0, 18-46-0, 0-46- 0, and 0-0-60) on pheasant reproduction and survival. One-half of the pens were fertilized with the recommended rate of pelleted fertilizer and the other half without fertilizer. Complete nest searches in July showed that nesting success was not significantly different (P>0.05) between treatments for both years. No significant difference (P>0.05) was found in clutch size or in number of ovulated follicles from control and experimental hens. Significantly more …

The object of this study was to determine the effect of PCB and DDT, DDD, DDE on the learning ability of penned white pelicans. Control, PCB, and DDT groups of penned white pelicans learned to …


Habitat Preferences And Food Habits Of Striped Skunks In Eastern South Dakota, Melvin S. Moe Jan 1974

Habitat Preferences And Food Habits Of Striped Skunks In Eastern South Dakota, Melvin S. Moe

Electronic Theses and Dissertations

Habitat preferences of striped skunks (Mephitis mephitis) in Brookings County, South Dakota, were determined rom the relationship of nighttime roadside indices to 25 habitat variables of 277, 1-square mile plots. Winter tracking was also conducted. Skunks were collected on the study area in 1972-1972, and contents of 59 stomachs and 63 colons were studied to determine food habits. Indices of prey abundance in different habitat types were obtained from snap-trap surveys. The 25 variables accounted for 14.9 percent of the variation in skunk numbers. The relationships of three of these variables to skunk numbers were significant (P<0.05). The significant variables and the variation accounted for by each were: (a) number of areas of idle grassland, 6.3 percent; (b) number of rockplies, 1.5 percent; and (c) acreage of idle grassland, 1.3 percent. Idle grasslands were the main activity centers of skunks tracked during the winter. Food habits were analyzed for the periods March-April, May-June, July-August, and September-November. Insects were the most frequently found food item in al time periods except March-April, during which mammals occurred more frequently. Mammals made up the largest volume of food in March-April and May-June. Amphibians made up the greatest volume in July-August, while amphibians, mammals, and insects were found in nearly equal volumes in September-November. Bird remains occurred during all time periods. Eggs were found in May-June and July-August. Meadow voles (Microtus spp.), the most frequent mammalian food item during all time periods, were common only in habitat types having heavy residual cover. Idle grassland is an important nestling cover for gamebirds and waterfowl. Since the number of areas of this cover type apparently has a stronger relationship with skunk numbers than its total acreage, grassland nesting cover might best be managed in large, homogeneous blocks. Areas managed in this way would probably support lower skunk densities than more diverse areas containing equal acreages of idle grassland, thus reducing nest predation by skunks. Skunk control programs should be most efficient when centered around idle grassland and rockplies.


Influence Of Vegetation On The Distribution Of Small Mammals On A Waterfowl Production Area, Douglas A. Searls Jan 1974

Influence Of Vegetation On The Distribution Of Small Mammals On A Waterfowl Production Area, Douglas A. Searls

Electronic Theses and Dissertations

. A study was conducted on a Waterfowl Production Area in Brookings County, South Dakota in 1972-73 to determine the distribution and abundance of small mammals. Three cover types, reseeded native grassed, brome-alfalfa, and bluegrass, were studied. Meadow voles (Microtus pennsylvanious), and deer mice (Peronyscus maniculatus) were captured most frequently. Jumping ice (Zapus hudsonius), masked shrews (Sorex cinerius), short tailed shrews (Blarins brevicauda), grasshopper mice (Omychomys leucogaster) and house mice (Mis musculus) were also taken. The bluegrass association had the highest number of small mammal captures and the reseeded native grass association has the least. There was no significant difference …


Volatility, Drift And Phytotoxicity Of Dicamba To Corn When Applied With Additives, Bart A. Brinkman Jan 1974

Volatility, Drift And Phytotoxicity Of Dicamba To Corn When Applied With Additives, Bart A. Brinkman

Electronic Theses and Dissertations

Herbicides have become an important asset to the farmer since the discovery of 2,4-D as a useful weed killer. Although herbicides are a relatively new and useful tool, various hazards are associated with their use. Drift and volatility are of primary concern. Air pollution is recognized as an environmental detriment to both plants and animals. The prevention of herbicide drift and volatility is necessary to maintain an environment suitable for many plant habitats. Dicamba (3,6-dichloro-o-anisic acid) is used to control broadleaf weeds in corn, small grains, lawns, and rangelands. Sometimes nontarget areas adjacent to crops are affected seriously because of …

Consumer Installment Loan Risk: A Discriminant Analysis, Ronald Edward Fisher Jan 1974

Consumer Installment Loan Risk: A Discriminant Analysis, Ronald Edward Fisher

Electronic Theses and Dissertations

All lending institutions are faced with the fact that a portion of their outstanding loans will not be repaid. A loan officer, or other designated individual, is normally charged 'it h the responsibility of evaluating loan applicants in terms of their comparative risks in order to reduce this inherent cost of doing business. The loan officer has traditionally evaluated consumer installment loan applicants using the three C's rule: character, collateral and capacity to repay, as his guideline for evaluating risk. The information required for this type of evaluation came from the data on the loan application, a credit check and …


Sulfur Supplementation With Soybean Meal Or Urea For Feedlot Lambs, Joseph Cletus Ebert Jan 1974

Sulfur Supplementation With Soybean Meal Or Urea For Feedlot Lambs, Joseph Cletus Ebert

Electronic Theses and Dissertations

One of the urgent tasks facing agricultural scientists throughout the world is that of supplying sufficient food of adequate quality to the ever-increasing human population. The problem is not only that of supplying calories but also providing adequate quantity and quality of protein. Ruminant animals have the ability to convert much plant energy, not utilizable or having low availability for man, and nonprotein nitrogen products into body tissues. Ruminant animals, therefore, can have a very important role in providing food for the human population. The most widely used nonprotein nitrogen compounds urea. The process of building amino acids into body …

The Effect Of Simulated Hail Damage On Oats, David Gaylord Hanson Jan 1974

The Effect Of Simulated Hail Damage On Oats, David Gaylord Hanson

Electronic Theses and Dissertations

With all of the advances in science and technology, the farmer is still helpless against the powers of nature. A natural disaster, such as a hailstorm, can seriously affect an individual fanner, or a small region. During the course of a growing season, the sum of these hailstorms can result in a substantial loss to the total farm economy. Hail insurance provides a way for farmers to protect themselves from losses due to hail, but the estimation of losses in a hailed field is a difficult job since the entire field is often hit leaving no check area from which …


Molecular Orbital Calculations For [Mo(Cn)₈]⁴⁻ An Investigation Of Eight Coordination Geometries, Patty S. Herman Jan 1974

Molecular Orbital Calculations For [Mo(Cn)₈]⁴⁻ An Investigation Of Eight Coordination Geometries, Patty S. Herman

Electronic Theses and Dissertations

Until the last twenty years only a few discrete 8-coordinate transition metal complexes were known. Increased interest in 8-coordination has led to the synthesis and characterization of a great many 8-coordinate compounds. Application of 3-dimensional X-ray analysis has made structural determination of these complexes much simpler. Two configurations dominate the stereochemistry of discrete 8-coordination, the D4d square antiprism and the D2d triangular dodecahedron. Both of these structures can be obtained by distorting the cube, a configuration not commonly observed. A 45° rotation of one square face of a cube about the perpendicular axis through that face results in the antiprism …


The Public Relations Efforts Of South Dakota Colleges And Universities As Reflected By The Attitudes Of South Dakota High School Seniors, Daniel F. Jorgensen Jan 1974

The Public Relations Efforts Of South Dakota Colleges And Universities As Reflected By The Attitudes Of South Dakota High School Seniors, Daniel F. Jorgensen

Electronic Theses and Dissertations

This study will concentrate on one small, yet vital, public--the public composed of high school seniors. If this public is "aware" of what the South Dakota colleges and universities have to offer, then the public relations programs of those schools are having some effect. If the students are preparing for a college career, then it is important to the future of the state's higher education that they are aware of the costs and the offerings of its schools. Daniel Gladstone, a high school senior from New Jersey, supported this thinking in a personal opinion column in "Saturday Review." He said …

Approximately one-fifth of the total cost of the project will be for drainage systems. The Bureau of Reclamation is responsible for the design of the Oahe project. They are presently using a transient drainage spacing equation developed by Glover in the design of the drainage system. The use …


Development Of A Control System For Positioning The Centerbody In A Choked Inlet, John Jacob Jibben Jan 1974

Development Of A Control System For Positioning The Centerbody In A Choked Inlet, John Jacob Jibben

Electronic Theses and Dissertations

Since the introduction of high bypass ratio turbofan engines, the noise problem from aircraft shifted primarily from jet noise to noise of turbomachine origin. The present dominant noise source is the inlet noise generated by the first compressor stage (or the fan). Acoustic liners to reduce this noise have met with only limited success since the noise reduction to cost ratio is quite low. There are also many technical problems with acoustic liners that are not completely solved. Another method is by means of the choked inlet. This device simply accelerates the air to sonic velocities in the opposite direction …


The Probability Of A Basketball Rebounding In Specific Areas After A Missed Shot Is Taken From A Certain Area, James Egge Jan 1974

The Probability Of A Basketball Rebounding In Specific Areas After A Missed Shot Is Taken From A Certain Area, James Egge

Electronic Theses and Dissertations

Rebounding in basketball has always been of concern and importance to coaches at all levels of competition. The collection of data concerning on-the-court performance of basketball players has increased greatly during the past twelve years; however, only limited rebounding statistics have appeared in recent studies. Allsen concluded that shots attempted from the right side have a tendency to rebound to the middle and right side. On the other hand, when shots were attempted from the left side a greater percentage of missed shots rebounded to the right side or middle area of the court. In Allsen's study there was equal …


A Study Of Selected Demographic Factors Associated With The Number And Characteristics Of Marriages Solemnized In South Dakota: 1960-1972, Jon Gregory Lundeen Jan 1974

A Study Of Selected Demographic Factors Associated With The Number And Characteristics Of Marriages Solemnized In South Dakota: 1960-1972, Jon Gregory Lundeen

Electronic Theses and Dissertations

The marriage statistics for South Dakota from 1960 to 1970 reveal that the number of marriages has steadily increased since 1960. The number of births, however, has steadily decreased in number in South Dakota since 1960. Perhaps this is understandable inasmuch as Paul H. Jacobson points out that the analysis and interpretation of marriage statistics is the least developed branch of American vital statistics. This is an important area for study, however, because any community is highly influenced by the proportion of its population that is single, married, widowed, or divorced. The marital condition of a population influences its birth …

Themes Expressed In The Rhetoric Of Two Women's Rights Movements, Ann Holt Logan Jan 1974

Themes Expressed In The Rhetoric Of Two Women's Rights Movements, Ann Holt Logan

Electronic Theses and Dissertations

Throughout American history, the question of women's rights initiated a substantial body of rhetoric. The two most prominent women's rights movements seem to be the woman's suffrage movement from 1848 to 1920 and the current women's liberation movement. The recurrence of organized movements on the subject of women's equal rights raises the question whether the themes expressed in the rhetoric of each movement are similar. Therefore, the purpose in this investigation was to discover the extent to which speaking on behalf of women's rights by women utilized recurring themes. The two most prominent women's rights movements seem to be the …


Relationship Between Pre-Meet Anxiety Level And Gymnastic Meet Performance In Women's Intercollegiate Gymnastics, Barbara Kae Langemo Jan 1974

Relationship Between Pre-Meet Anxiety Level And Gymnastic Meet Performance In Women's Intercollegiate Gymnastics, Barbara Kae Langemo

Electronic Theses and Dissertations

Competing in athletics, by their very nature, subjects’ participants to many anxieties and stresses. Each person is an individual in the way he/she responds to certain stimuli and the responses are dependent upon social-background, personality, intelligence and emotional status. All of these factors intertwined dictate how an individual reacts to a variety of stimuli. Each competitor will differ in the degree of anxiety felt and the intensity may dictate how each will perform during competition. This one factor, anxiety, may explain why two individuals equal in skill level and physical ability perform so differently during competition in any given sport. …


Computerized Construction Of A Seasonal Flow-Duration Table, Gregory C. Meyer Jan 1974

Computerized Construction Of A Seasonal Flow-Duration Table, Gregory C. Meyer

Electronic Theses and Dissertations

Various graphical methods have been developed to handle the statistical data gathered for hydrological studies. Those most familiar are probably the hydrograph, the mass curve, and the flow-duration curve. The first two graphical techniques have been in use for numerous years and as a result, are described in many textbooks. The first published writings dealing with the flow-duration curve are believed to have been released in about 1878. However, the general use of the flow-duration curve started around the year 1915, but as late as 1934 it was felt that many of the fundamental principles of the flow-duration curve were …


Groundwater Quality In Water Supply Wells Surrounding The Sanitary Landfill At Brookings, South Dakota, David C. Odens Jan 1974

Groundwater Quality In Water Supply Wells Surrounding The Sanitary Landfill At Brookings, South Dakota, David C. Odens

Electronic Theses and Dissertations

In 1960, the city of Brookings, South Dakota began operating a solid waste disposal site in an abandoned gravel pit approximately two miles south of the city. Because the surrounding residences obtain their water supply from groundwater found in a shallow aquifer in the area, immediate concern was expressed about the effects of the sanity landfill of groundwater quality. In response to the objections to the refuse disposal site raised by-the people in the area, the city of Brookings initiated a study of groundwater quality at the site in 1960. Later, in 1964, a comprehensive study of the groundwater within …

Energy Sources In Starter Diets For Early Weaned Pigs, Leon Jon Reiner Jan 1974

Energy Sources In Starter Diets For Early Weaned Pigs, Leon Jon Reiner

Electronic Theses and Dissertations

The swine industry is largely dependent upon feed grains as major dietary ingredients because of the very limited ability or the pig to utilize roughages. The dependence upon feed grains puts the pig in direct competition with humans for available food supplies. Grains are an excellent source of carbohydrate but in general are a poor supplier or protein. Raising the level and quality or protein in corn and oats wou1d be of great economic and nutritional value. New uses of high protein ingredients, which were once used as supplementa1 protein for swine, are continually being implemented to help meet the …


Rna And Cell Volume Distribution Analysis Of Vee Virus Infected Mosquito Cell Cultures, Clayton Werner Naeve Jan 1974

Rna And Cell Volume Distribution Analysis Of Vee Virus Infected Mosquito Cell Cultures, Clayton Werner Naeve

Electronic Theses and Dissertations

The subject of this investigation is the Aedes albopictus (Aal) cell line infected with Venezuelan equine encephalomyelitis (VEE) virus, a group A arbovirus. This cell-virus system is an ideal choice for both types of analysis. Certain of the group A arboviruses have been looked at as "models" for ribovirus replication and thus have several advantages for an FNA study. The genome is a single strand of RNA containing only about a dozen cistrons, the virions contain only one polypeptide in the nucleocapsid and one in the envelope, and infectious RNA is easily isolated and titrated by sensitive plaque assay. In …


The Effect Of Subsurface Layered Trifluralin And Dicamba On Field Bindweed, Winter Wheat, And Corn, William Ben O'Neal Jan 1974

The Effect Of Subsurface Layered Trifluralin And Dicamba On Field Bindweed, Winter Wheat, And Corn, William Ben O'Neal

Electronic Theses and Dissertations

A new approach to controlling field bindweed is being evaluated and is the subject of this thesis. Recent research has found that field bindweed is effectively controlled by a uniform layer of trifluralin 4 to 6 inches beneath the soil surface. Field bindweed growth is contained beneath the layer. This method appears promising for eradication of field bindweed if the roots are physiologically weakened or food reserves depleted enough that eradication can be obtained prior to dissipation of the trifluralin layer. Trifluralin inhibits root growth on numerous plant species. These researchers generally found radial enlargement of the primary roots near …


Synthesis Of S-(1-Diazo-2,2,2-Trifluorethyl) Cysteine Dioxide : A Potential Gutamine Antagonist, Robert M. Olson Jan 1974

Synthesis Of S-(1-Diazo-2,2,2-Trifluorethyl) Cysteine Dioxide : A Potential Gutamine Antagonist, Robert M. Olson

Electronic Theses and Dissertations

Compounds affecting the utilization of L-glutamine have a comparatively long history in the field of cancer chemotherapy. The Streptomyces antibiotics, azaserine (0-diazoacetyl-L-serine) and DON (6-diazo-5-oxo-L-norleucine) inhibit to varying extents those aminations in which glutamine serves as an amino group donor. This inhibition is achieved in at least one case by the glutamine antagonists alkylating the sulfhydryl group of the enzyme that catalyzes the amino group transfer of glutamine. A distinguishing feature of the diazo analogs of glutamine is the very reactive diazo group that enhances nucleophilic reactions on the adjacent carbon atom. Because of the increased reactivity created by the …

South Dakota Gubernatorial Inaugural Addresses, 1889-1931, Terry L. Peterson

Electronic Theses and Dissertations

For the purposes of this study it was judged necessary to define two terms: 1. Rhetorical environment has been defined as including the place of the inaugurals, the audiences present, and the issues prominent in the state at the time an inaugural address was delivered. 2. A theme is defined as an original statement that encompasses an overall idea and may have supporting assertions. A theme is subordinate only to the thesis and is coordinate with other themes. This particular study began as an analysis of all gubernatorial South Dakota inaugural addresses from 1889 through 1973. However, after the research …
