Measuring Water With Parshall Flumes, Gaylord V. Skogerboe, M. Leon Hyatt, Joe D. England, J. Raymond Johnson

Reports

Preface: As the value of water increases, the extent to which measurement is employed in an irrigation system also increases. Additional flow measurements provide information for improved management of the water supply. Good water management requires accurate measurement. Many devices have been developed for this purpose and are in use. Included among them are weirs, orifices, calibrated gates, Parshall flumes, and current meters. Of these, the Parshall flume is one of the most widely accepted and used. Presented in this publication is a discussion concerning the use of Parshall flumes for measuring water, including the utilization of a new approach …

Application Of Electronic Analog Computer To Solution Of Hydrologic And River Basin Planning Problems: Utah Simulation Model Ii, J. Paul Riley, Duane G. Chadwick, Jay M. Bagley

Reports

As demands upon available water supplies increase, there is an accompanying increase in the need to assess the downstream hydrologic system. At Utah State University this problem is being approached by electronic analog simulation of the hydrologic system. Modeling concepts are based upon the development of basic relationships which describe the various hydrologic processes. Within a system, these relationships are linked by the continuity -of-mass principle which requires a hydrologic balance at all points. Once established, the model is applied to any particular geographic unit by determining the appropriate constants of the hydrologic equations. The analog computer is ideally suited …

A Study Of The Development Of A Heuristic Program That Solves Symbolic Laplace Transformation Problems, Arthur E. Zackrison

Masters Theses

"A medium-speed general purpose digital computer (IBM 1620 Model II) was programmed to solve symbolic Laplace transformation problems. Although the applied mathematician and modern engineer has many uses for the symbolic solution of a problem, the potential of symbolic manipulation by a computer has not yet been sufficiently developed to help them because of many problems. This paper discusses the program and based on the author’s experience with it’s [sic] performance, clarifies the position of several of these difficulties and reaches some conclusions concerning computer solution of such problems"--Abstract, page ii.

Limnology Of Three Farm Ponds In South-Central South Dakota, Larry Kim Graham

Electronic Theses and Dissertations

Physical, chemical, and biological aspects of three farm ponds in south-central South Dakota were studied from June 1964 until December 1965. Maximum water temperature at the surface reached 25.2 C, while water temperatures at the bottom of the ponds were about 2 to 4C lower than the surface. Light transmission was influenced by turbidity but generally penetrated to the bottom of the ponds except during periods of cloudy ice and snow cover. Dissolved oxygen was near saturation during periods of open water. Most chemical ions in the ponds increased annually from a winter minimum to a spring maximum. Total dissolved …

The Faraday Rotation And Dispersive Doppler Effects In The Ionosphere At Oblique Incidence, Charles Roland Baugher Ii

Masters Theses

"Integral equations for the isotropic and anisotropic ray path of a radio wave propagating through the ionosphere are developed. These equations assume a spherically stratisfied ionosphere and are equivalent to a detailed ray-tracing process. A method is devised to utilize these equations in the evaluation of combined Faraday rotation and dispersive Doppler data from earth satellites for subionospheric electron content. The method, which corrects for horizontal ionospheric gradients, is applied to data from the Explorer 22 satellite and some preliminary results are discussed"--Abstract, page ii.

Structure Contours On The Top And Base Of The M Bed, The Relationship Of Mineralization To Structures, And The Variation Of The M Bed Thickness In The Tri-State District, Missouri, Kansas And Oklahoma, Arvind A. Desai

Masters Theses

"Regional structure and thickness of a single horizon, the M bed, have been studied in the Tri-State district by picking the top and base of the M bed in the logs of 557 selected drill holes and contouring this data together with the aid of local detailed structural information available for individual mining fields. Structures determined from these data were compared to the positions of mined mineralization to determine the control of regional structure upon the localization of ore. Variations in the M bed thickness were compared to the positions of fields of mineralization to examine possible spatial relationships which …

The Construction Of A Multi-Threshold Foil For Fast Flux Measurements, Michael Henry Holkenbrink

Masters Theses

"The construction of a multi-threshold foil for fast neutron flux measurements is investigated. The factors governing the selection of the materials are the energy response of the given reactor, the half-life of the daughter, the prominent gamma ray emitted during decays, the power level of the reactor, the availability of adequate cross section data, and the alloying properties of the composite foil. A ternary system was chosen as a compromise between the difficulty of fabrication and the amount of information gained from one foil. The particular system chosen was In- P- Fe. The threshold reactions of these elements are In¹¹⁵ …

Tectonic Analysis Of Mare Humorum On The Lunar Surface, Adnan Said Abul-Husn

Masters Theses

"Morphology and internal structures of surface features of the Mare Humorum area were interpreted from photographs and topographic maps. The postulated origin of certain features is based on analog comparisons with known terrestrial features. The laws of crate ring and a newly developed computer program were applied to two representative classes of craters to determine the possibility of a meteoritic impact origin. Some of the craters formed by meteoritic impact and others, including those with a radius larger than 10 Km, probably resulted from volcanic activity.

Mare Humorum formed from centripetal subsidence followed by extensive lava eruptions. Spacially related rilles …

Mobility And Behavior Of Raccoons In Eastern South Dakota, George L. Geis

Electronic Theses and Dissertations

Introduction: Increasing populations of raccoons (Procyon lotor) and reports of depredation on upland game, poultry, and garden crops indicated a need for research concerning behavior, mobility, and range of raccoons. The raccoon has seemingly adapted to the dry environment of the northern agricultural plains. According to records, the original range apparently did not extend into South Dakota. Lewis and Clark did not report raccoons when they traveled along the Missouri River in 1804 and 1806 (Coues, 1893). Although Visher (1918) noted that raccoons were not rare in wooded areas along streams in western South Dakota, he made no mention of …

Contribution À La Systématique Des Stenasellinae D'Afrique (Crustacés, Asellotes), Guy Magniez

International Journal of Speleology

From 1897 to 1962, many species have been described as belonging to the genus Stenasellus Dollfus. Among all these the forms from Central Africa and one of Western Africa are not conform to the generic description of Racovitza 1924 obliging us to institute two new genera, Metastenasellus and Parastenasellus. The archaeic Asellota belong to the genus Stenasellus Dollfus, Johannella Monod, Metastenasellus nov.gen. and Parastenasellus nov. gen. are thus grouped in a sub family of Stenasellinae and the relationship between the different groups has still to be explained.

Notulae Orthopterologicae Xxi - Le Dolichopoda Della Francia E Della Spagna, Baccio Baccetti

International Journal of Speleology

The revision of French-Iberian Dolichopoda has led to the identification of four different species of Dolichopoda s. str. One of these (D. azami) seems to have a large geonomy in the French Alps and it had already been noticed in Italy, too. A second species (D. chopardi m.), still new to science, seems to be restricted to the Maritime Alps; the third and the fourth (D. linderi and D. bolivari), already well known, seem to be localized in the Pyrenees and the Cevennes. Owing to their morphological characters Dolichopoda azami and chopardi constitute a very …

Re-Evaporation Nuclei And Evaporation In A Wilson Cloud Chamber, James G. Smith

Doctoral Dissertations

"Experimental techniques are developed for observing droplet evaporation in the submicroscopic size range. An expansion-compression cloud chamber with an atmosphere of tank helium saturated with water vapor is employed. This work was undertaken with the aim of examining submicroscopic droplet behavior and the existence of re-evaporation nuclei, a form of memory effect.

The theories of evaporation and nucleation on submicroscopic drop residues were re-examined, and alterations which appear to be consistent with the results of this work were incorporated into the evaporation theory.

The observed continually decreasing evaporation rate with diminishing droplet size confirms the existence of re-evaporation nuclei, but …

Diffusional Drop Growth In A Supersaturated Atmosphere, John C. Carstens

Doctoral Dissertations

"The effect which a growing droplet has on the supersaturated atmosphere surrounding it is analyzed by assuming a macroscopic diffusional growth mechanism involving both heat and vapor. The problem is solved, for cloud-chamber conditions, first for very short times assuming a fixed radius, and then for longer times assuming the establishment of "quasi" steady-state conditions. Knowledge of the way in which droplet growth affects supersaturation is important in the evaluation of nucleation rates"--Abstract, page ii.
