A Study Of The Compressibility Of Silty Soils., Marvin L. Byington Jan 1967

A Study Of The Compressibility Of Silty Soils., Marvin L. Byington

Masters Theses

"This study has been conducted to determine the applicability of the Terzaghi Theory of Consolidation and to determine the compressibility of silt soils with varying clay content. A pure silt was extracted from the Lebanon Silt Loam and mixed with varying amounts of the Onyx Cave Illite-Chlorite Clay. The compressibility of these mixtures was determined and an attempt made to apply the Terzaghi Theory in the analysis. It was found that the compressibility of soils high in silt content is very low. It was also found that the Terzaghi Theory may be applied to mixtures of 15 percent or more …


Effects Of Mixing Procedure Upon Uniformity Of Fibre Reinforced Concrete, Donald E. Nortrup Jan 1967

Effects Of Mixing Procedure Upon Uniformity Of Fibre Reinforced Concrete, Donald E. Nortrup

Masters Theses

"This thesis describes the effects of several methods of introducing wire fibres into a concrete mix upon the uniformity of wire fibre reinforced concrete. Various mechanical and manual methods of introducing the fibres were used and comparisons of the methods were based upon variability in splitting tensile strength and the quantitative distribution of the fibres as determined by visual inspection of sawed cylinders. Test results show that the tensile strength of concrete is increased appreciably by the inclusion of steel wire fibres in the mix and the uniformity of strength is similar to that of unreinforced concrete. The methods of …


The Measurement Of Explosively Induced Stresses In Rock-Like Materials With A Capacitive Transducer, Vincent Paul Crane Jan 1967

The Measurement Of Explosively Induced Stresses In Rock-Like Materials With A Capacitive Transducer, Vincent Paul Crane

Masters Theses

"A capacitive transducer was developed for measuring the free surface motion in Hydrostone blocks loaded by an explosive plane wave generator approximately one foot from the specimen. The charge to specimen distance was adjusted to produce a single spall, the position of the fracture being noted on the recovered specimen. The longitudinal wave velocity in each specimen was determined by the ultrasonic pulse technique before each shot. From the above measurements the stress, strain and strain rate at the point of fracture were determined. An attempt was made to determine the actual fracture time with imbedded [sic] conductive graphite rods, …


Quality Of Surface And Subsurface Water In A Missouri Carbonate Karst Terrain (Dry Fork, Norman, And Benton Creek Watersheds), James Chi Huang Jan 1967

Quality Of Surface And Subsurface Water In A Missouri Carbonate Karst Terrain (Dry Fork, Norman, And Benton Creek Watersheds), James Chi Huang

Masters Theses

"Little is known about the effect of carbonate karst terrain on water quality in the United States. Karst topography occurs over a large portion of Missouri and over a significant part of other midwestern states. The objectives of this study were the determination of the quality of surface and subsurface water in carbonate karst terrain and the investigation and evaluation of the effect of rainfall and runoff on water quality in the Meramec Spring area, east of Rolla, Missouri, during both the dry and wet seasons over the period of one year. Water samples were collected at a large number …


Some Effects Of Nickel On The Microbial Population Of Activated Sludge, Virgil Eugene Carr Jan 1967

Some Effects Of Nickel On The Microbial Population Of Activated Sludge, Virgil Eugene Carr

Masters Theses

"The purpose of this investigation was to study the effects of nickel on the microbial population of activated sludge, to establish a relationship between effluent quality and changes in microbial population, and to determine the fate of nickel applied. Five one liter fill and draw activated sludge units were fed settled domestic sewage and received constant daily nickel doses of 1-10 mg/l, and a 50 mg/l slug dose applied after 27-30 days of operation. The parameters used were the chemical oxygen demand (COD) of the effluent and membrane filtered effluent, mixed liquor and effluent total suspended solids, mixed liquor volatile …


The Influence Of A Fixed Failure Plane On The Direct Shear Test, Kenneth Hodges Bell Jan 1967

The Influence Of A Fixed Failure Plane On The Direct Shear Test, Kenneth Hodges Bell

Masters Theses

"The analysis of the direct or box shear test for determining the shear strength of a soil makes use of the assumption that the failure plane coincides with the plane of separation between the two halves of the box. Hvorsley, Roscoe, Hansen and others have theorized and experimentally shown that this is not always the case. The stress distributions on the failure plane, however it may be oriented, are not as uniform as generally assumed. This investigation was carried out to compare direct shear tests run on granular, air dry material where the failure was allowed to take place naturally …


Stress Analysis Of A Wall Footing Subjected To External Vertical Loads And Overturning Moments By The Finite Element Method, Adil Godiwalla Jan 1967

Stress Analysis Of A Wall Footing Subjected To External Vertical Loads And Overturning Moments By The Finite Element Method, Adil Godiwalla

Masters Theses

"This investigation pertains to the stress analysis by the finite element method of a wall footing subjected to external vertical loads and external overturning moments. This problem has been reduced to a two-dimensional stress analysis problem by taking a unit length of the wall. A rectangular plate - element is used throughout this investigation. The development of the matrix equations is shown and the solution is performed by digital computer. Stresses in the horizontal direction show essentially linear variation which is in agreement with simple structural theory, while stresses in the vertical direction show severe perturbation near the column load. …


The Recovery And Characterization Of Organic Micropollutants From Missouri Subsurface Waters, John Warren Smith Jan 1967

The Recovery And Characterization Of Organic Micropollutants From Missouri Subsurface Waters, John Warren Smith

Masters Theses

"The main objectives of this investigation were the recovery and partial characterization of organic micropollutants from Missouri subsurface waters and the evaluation of the number of filters in series required for effective removal of organic materials from water using the Carbon Adsorption Method.

The organics were recovered from a spring and two deep wells using three large capacity (1. 5 cu. ft.) activated carbon filters in series. Chloroform and ethanol were employed as primary elutants, but acetone and benzene were also investigated. Characterization was by organoleptic, chemical, and biological determinations, toxicity measurements, and solubility partitioning.

Organic materials were found in …


Gap-Graded Gravel For Asphaltic Paving Mixtures, Ernest Harrington Martin Jan 1967

Gap-Graded Gravel For Asphaltic Paving Mixtures, Ernest Harrington Martin

Masters Theses

"The objective of this investigation was to determine if naturally occurring gap-graded gravel can produce asphaltic mixtures meeting minimum requirements for satisfactory pavement behavior.

Ten gap-graded mixes were blended by eliminating certain intermediate sized fractions or combination of fractions from the gradation of a control mix. The weight of the fractions eliminated was distributed to either the coarser or finer aggregate fractions.

All specimens were prepared and tested in strict accordance with procedures set forth in ASTM Designation D1559, "Resistance to Plastic Flow of Bituminous Mixtures Using Marshall Apparatus."

The physical properties compared and analyzed were (1) unit weight, (2) …

Geographical Characteristics Of Early Mormon Settlements, John Haws Baum Jan 1967

Geographical Characteristics Of Early Mormon Settlements, John Haws Baum

Theses and Dissertations

Considerable literature has been written about the Mormons and their settlement of the lands within the Great Basin; yet no one has produced a systematic study which analyzes the following geographical factors: What pattern of land occupancy was actually used by these early pioneers? Which physical characteristics determined the selection of a site for the Mormon village? What type of city survey pattern was instigated as towns were established along the eastern margin of the Great Basin? What was the relationship between the forts and the settlements in their lay-out patterns? As these questions were systematically analyzed new findings were …
