Also the importance of joint economic-agronomic research efforts, methodologies and applications of agricultural production functions are cited.

The second section includes the presentation data and postulated functional relationships in estimating production functions. Model building programs are used in developing three dimensional figures, which aid in the selection of …

Structural Geology Of The Oxford Peak Area, Bannock Range, Idaho, Larry C. Raymond

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The mapped area, in southeastern Idaho, includes part of the Bannock Range, on the west, and Cache Valley, on the east. It is centered about 13 miles northwest of Preston, Idaho, and measures 12 miles in the north-south direction and 8.5 miles in the east-west direction.

The Bannock Range, in the western part of the mapped area, consists of Precambrian and Cambrian stratigraphic units. The Precambrian units are as follows: (1) lower Precambrian argillite, (2) Precambrian quartzite, and (3) upper Mutual Formation. The Brigham Formation, which overlies the Mutual, is probably of Cambrian age; however, the lower part may be …

Spawning And Early Life History Of Largemouth Bass (Micropterus Salmoides) In Wahweap Bay, Lake Powell, Kent D. Miller

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Spawning time and habitat of largemouth bass, survival of embryos, and growth and food habits of fingerlings were studied in 1968 and 1969 at Wahweap Bay, Lake Powell. Spawning began in mid- to late-April, when mean daily water temperature at nesting depths was 14.4-15.0 Centigrade (58-59 Fahreheit), and continued until mid-June. Most spawning took place on the northeast shore of the bay. Sandstone rubble was the most commonly used bottom type for nesting, either at the base of ledges or around large sandstone boulders. Mean nest depth increased from 1.63 meter to 4.54 meters (5.36 feet to 14.90 feet) in …

Resource Requirements Determination (Based On Statistical Methods), Robert L. Howard

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Two methods of determining resource requirements at an Air Force maintenance depot were developed.

The first method is designed for new workloads and is based on infinite queuing theory formulas. Tables have been developed for this method.

The second method is designed for workload with, at minimum, several months of historical data. An optimum fit test was designed to aid in fitting and smoothing the empirical data to the normal distribution. These data are then input to simulation model for determination of resource requirements.

Integral Representation Theorems, Leiko Hatta

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Since F. Riesz showed in 1909 that the dual of C[0,1] is BV[0,1] (the functions of bounded variation on [0, 1] with || g ||_BV = V(g)) via the Stieltjes integral, obtaining representations for linear operators in various settings has been a problem of interest. This paper shows the historical manner of representations, the road map type theorems and representations obtained via the v-integral.

Fitting Some Families Of Contagious Distributions To Biological And Accident Data, Yung-Sung Lee

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Four families of contagious distributions--generalized Poisson distributions, generalized binomial distributions, generalized Pascal distributions, and generalized log-zero distributions--are investigated in this thesis.

The family of generalized Poisson distributions contains five distributions: the Neyman Type A, the "Short," the Poisson binomial, the Poisson Pascal, and the negative binomial. The family of generalized binomial distributions contains eight distributions: the binomial Poisson, the binomial binomial, the binomial Pascal, the binomial log-zero, the Poisson with zeros, the binomial with zeros, the Pascal with zeros, and the log-zero with zeros. The family of generalized Pascal distributions contains four distributions: the Pascal Poisson, the Pascal binomial, the …

The Effectiveness Of Categorical Variables In Discriminant Function Analysis, Preston Jay Waite

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A preliminary study of the feasibility of using categorical variables in discriminant function analysis was performed. Data including both continuous and categorical variables were used and predictive results examined.

The discriminant function techniques were found to be robust enough to include the use of categorical variables.

Some problems were encountered with using the trace criterion for selecting the most discriminating variables when these variables are categorical. No monotonic relationship was found to exist between the trace and the number of correct predictions.

This study did show that the use of categorical variables does have much potential as a statistical tool …

The Poincaré Conjecture, Joseph D. Peck

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The central theme for this paper is provided by the following three statements:

(1) Every compact connected 1-manifold is S1.

(2) Every compact connected simply connected 2-manifold is S2.

(3) Every compact connected simply connected 3-manifold is S3.

We provide proofs of statements (1) and (2). The veracity of the third statement, the Poincaré Conjecture, has not been determined. It is known that should a counter-example exist it can be found by removing from S3 a finite collect ion of solid tori and sewing them back differently. We show that it is not possible to find a counterexample by removing …

Effect Of Time And Rate Of Application Of Nitrogen On The Yield Of The Mexican Wheat Under The Semi-Arid Conditions Of Tunisia, Habib M. Halila

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The effect of the time and rate of application of nitrogen on the yield of high yielding varieties of wheat was studied under the semiarid conditions of Northern Tunisia.

Analysis of the experimental data showed that nitrogen increased the yield of wheat in most locations which were chosen for this experiment.

In high rainfall areas, late application of nitrogen (tillering, jointing stages) was more effective than early applications. The optimum yield was obtained by applying 90 kilograms of nitrogen per hectare.

In the medium to low rainfall area, early applications (seeding time) were more effective than the late ones. The …

Recommendations Regarding The Instruction Of Fluid Power In Utah, Ronald C. Baker

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The fluid power systems equipment industry has shown a 117 percent growth from 1957 to 1968.

This impressive growth rate is critically affected by a shortage of competently trained workers.

The needs of selected Utah industries for trained personnel in fluid power were studied, and the results were projected from the sample to the state of Utah.

The skill levels most in demand were skilled, two-year technician, and semi-skilled.

Industries indicated that training to meet their needs could be conducted by on-the-job training, inplant schools, special schools, adult education programs, vocational high school programs, tow-year vocational school programs, two-year university …

Relationship Of The Soil Water Content And Microclimate To The Plant Growth Water Use Relationship Of Several Plants, Philip Dean Sandberg

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Studies involving field plots, lysimeters, and garbage can lysimeters showed that an intermediate soil water level produced the most growth for a given amount of water use by oats, corn, and barley. For crested wheatgrass the lowest water level produced the most growth per water used. Field plots which were covered with sheet metal between the rows produced more plant growth per water used than the uncovered plots for the crops used in this study. One year's data were obtained on the effect of positioning the garbage can lysimeters. One half of the cans were placed on the soil surface …

Linear Programming As A Decision Tool In Cheese Manufacturing Plants, Mark S. Huber

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This thesis considered the potential benefits of employing linear programming in cheese manufacturing plants as a decision tool for management. Its potential has been enhanced by the recent approval of acid orange 12 as a chemical for testing the percent protein in milk; therefore, a practical test is now available for monitoring protein as well as milk fat in milk manufacturing and fluid milk plants.

Seven models, each one differing only in the milk fat and protein percentages or means of standardizing the cheese milk, were manipulated individually and simultaneously to test the managerial benefits of linear programming under various …

An Economic Appraisal Of On-Farm Water Management Practices In Developing Countries: A Study Of Summer Rice Production In Guayas Rivers Basin, Ecuador, Thomas L. White

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The primary objective of this study was to examine rice production methods, with special emphasis on irrigation-water management practices used by producers from all levels of management in the Guayas River Basin, Ecuador. To do this, rice producers were divided into four categories on the basis of the level of mechanization of their operation, use of purchased inputs, and the level of investment in irrigation facilities and general management practices. The levels of investment in irrigation facilities ranged from 7,000 to 500 sucres per hectare, and mechanization of production varied from almost total use of machinery for cultivation operations to …

Economic Impact Of Meeting Environmental Standards On Utah Cattle Feeders, P. Parry Olson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This thesis is an analysis and description of pollution problems caused by large feedlots in Utah. A description of pollution caused by cattle feedlots is undertaken as part of the study.

The 26 feedlots analyzed had a capacity to/or did feed over 1,000 head. They were broken down into four groups on the basis of their pollution problems: those having no apparent pollution problem, those having minor problems, those having major problems, and those requiring relocation.

The cost impact of meeting environmental standards with regard to runoff control was found to be very slight for the cattle feeding industry as …

The Effect Of Early Spring Clipping And The Level Of Nitrogen Fertilizer On The Yield Of Improved Pastures, North Logan, Utah, Dechar Sumrit

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The influence of agronomic practices on forage production and chemical composition of grass-legume pasture mixture was studied at the Utah State University Dairy Farm, North Logan, Utah, during spring and summer, 1970. The soil is a well-drained Millville silt loam that has about a 1 percent slope. It is high in potash, phosphorus, and lime, having a pH of 7.9.

Analysis of the clipping management showed that the early spring clipping decreased the yield of forage. The losses in total yield due to spring clipping were approximately four to five times the yields received in early spring clipping. The grasses …

The Post-Reinforcement Pause And Terminal Rate In Fixed-Interval Schedules, Charles A. Lund

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

California Quail were exposed to fixed-interval schedules whose values ranged from FI 90 to FI 180. Post-reinforcement pause lengths and terminal rates were recorded and grouped into relative frequency distributions. The relative post-reinforcement pause length was found to be an increasing function of FI value such that at larger FI values a proportionally greater period of time was taken up by the post-reinforcement pause. Terminal rate (rate during the final 20% of the interval) was a decreasing function of FI value. The large amounts of variability in terminal rates observed indicated that terminal rate in fixed-interval schedules is not constant …

I. Studies Toward The Synthesis Of Echinodithianic Acid And Ii. The Temperature Dependent Nmr Spectrum Of Methyl N-Acetylsarcosinate, Alan Leroy Love

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Approaches to the preparation of echinodithianic acid (5) from 2,5-dicarbomethoxy-1,4-dithiane (1) were not successful, due to the inability to carboxylate or carboalkoxylate 1 at carbons 2 and 5. Studies toward the synthesis of 5 utilizing methyl 2-acetamidoacrylate (8) have been investigated. The electrophilic addition of sulfur dichloride to 8 yielded bis-(2-acetamido-2-carbo-methoxyvin-1-yl) sulfide, while the addition of thiocyanogen chloride to 8 produced methyl 2-acetamido-3-thiocyanato-acrylate.

As electrophilic additions of unsymmetrical dipolar reagents to methyl 2-acetamidoacrylate (8) are not reported in the literature, the addition of hydrogen bromide to 8 was studied to determine the orientation effect of the acetamido group.

Methyl 2-acetamido-2-bromopropionate …

Torus Knots, David S. Bradley

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

We have compiled here many interesting results concerning a particular collection of knots called torus knots. Torus knots are merely simple closed curves imbedded in an unknotted torus T² in E³. We show that the fundamental groups of T², π(T²), is the direct product of the additive group of integers with itself. The ordered pair (p, q) in Z x Z determines an equivalence class of loops on the torus, and we show in Section II that the class [(p, q)] contains a loop whose image is a simple closed curve if and …

A Monte Carlo Evaluation Of A Nonparametric Technique For Estimating The Hazard Function, Sheng Jia Lin

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

This research is primarily concerned with the estimation of the Hazard functions, the Hazard function is the failure rate at time t, and is defined as -R '(t)/R(t), so it plays an important role in Reliability.

In order to compare and evaluate the estimation methods, it is convenient to select one distribution in this research. Since the Weibull distribution is a useful distribution in Reliability, the Weibull distribution is used in this paper.

A Study Of A Portion Of The Distributive Education Teacher Preparation Program At Utah State University, J. Grant Brough

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

The major purpose of distributive education is to prepare the student for entry-level employment in distributive occupations. This preparation should help workers become successful and advance in their chosen field of distributive occupations.

No matter how instruction is organized, when it is identified as vocational distributive education, there are no differences in the results desired. Students are to be able to meet employment qualifications with the confidence and the competencies necessary to begin marketing and management careers.

To meet this goal, the student should qualify himself to receive satisfaction and contentment in his work. Sidney P. Marland's deep expression in …

Effects Of Season And Intensity Of Use On Desert Vegetation, C. Wayne Cook

UAES Bulletins

Desert ranges of the Great Basin area support about 9 million cattle and sheep for 5 to 6 months each winter. Many of these same ranges are used by cattle year-long.

If forage is not available on desert ranges, livestock have to be wintered on farmsteads or in feedlots after they are forced from the mountains and foothills by snow. Since feeding during the winter is expensive and reduces the economic efficiency of the range livestock operation, there is real advantage in properly managing the desert ranges and conserving the supply of forage for winter grazing.

Managing desert ranges for …
