The Effect Of Cadmium On Anaerobic Digestion, Lyle Lynn Pruitt Jan 1965

The Effect Of Cadmium On Anaerobic Digestion, Lyle Lynn Pruitt

Masters Theses

"The main purpose of this study was to determine the effect of cadmium on anaerobic digestion. Metal concentrations in the form of regular and slug doses were considered. The possibility of acclimating anaerobic bacteria to higher cadmium levels was studied, and attempts were made to reestablish digestive action through re-seeding in digesters overcome by high cadmium concentrations"--Abstract, page [ii].


The Effect Of Submerged Jets On The Hydraulic Jump, Harvey E. Jobson Jan 1965

The Effect Of Submerged Jets On The Hydraulic Jump, Harvey E. Jobson

Masters Theses

"Tests were performed in order to determine the effects of forcing submerged jets of water into the base of a hydraulic jump. The specific energy of the water leaving the hydraulic jump, the length and the wave formation properties of the jump which had been modified by the introduction of submerged jets were determined and compared with the same characteristics of a normal hydraulic jump and a hydraulic jump which had been modified by the use of baffle piers.

Test results indicate: (a) the quantity of water flowing through the submerged jets is a primary factor in determining the specific …


Infinite Beams On An Elastic Foundation, Shi-Peing Chang Jan 1965

Infinite Beams On An Elastic Foundation, Shi-Peing Chang

Masters Theses

"In this paper a partial differential equation for the analysis of beams resting on an elastic foundation under dynamic load is presented. A solution for this equation is derived, and solutions for various boundary conditions of infinite beams resting on an elastic foundation are discussed. The application of the equation is demonstrated by an example of a moving load traveling along an infinite beam"--Abstract, page ii.


Effects Of Internal Pressure Upon The Buckling Of Thin Circular Cylindrical Shells Under Axial Compression, Leroy E. Thompson Jan 1965

Effects Of Internal Pressure Upon The Buckling Of Thin Circular Cylindrical Shells Under Axial Compression, Leroy E. Thompson

Masters Theses

"An experimental investigation was made of the effects of internal pressure upon the buckling of thin circular cylindrical shells under axial compression. A comparison was made of the experimental and theoretical results; the latter were derived from the large-deflection theory. Results showed that the internal pressure had an appreciable strengthening effect upon the buckling of the cylindrical shell. The comparison showed that the experimental results were lower than the theoretical results for a given internal pressure. The discrepancy between the results can be expected since there were factors not included in the theory: imperfections, end conditions, lengths, and material irregularities"--Abstract, …


Field Permeability Determination Of Partially Saturated Fine Grained Soil, Edward G. Rapp Jan 1965

Field Permeability Determination Of Partially Saturated Fine Grained Soil, Edward G. Rapp

Masters Theses

"The determination of water permeability through a soil is necessary to estimate seepage losses from small reservoirs. At the present time, the methods available to conduct this determination in partially saturated fine grained soils are expensive and in most cases not commensurate with the cost or importance of the individual structure. This investigation was conducted to evaluate the use of a proposed, potentially inexpensive field procedure in this situation. A modified borehole apparatus was utilized in field tests to determine the permeability of a partially saturated soil deposit in place. Undisturbed samples from the same location were tested in the …


An Investigation Of Continuous Prestressed Concrete Structures, Ping-Chi Mao Jan 1965

An Investigation Of Continuous Prestressed Concrete Structures, Ping-Chi Mao

Masters Theses

"This thesis presents an analysis of the behavior of continuous prestressed concrete structures. From this analysis the governing equations for various types of geometry for prestressing cables are derived. The calculation of fixed-end moments due to the prestressing force using the equations derived is quite cumbersome, however, in order to simplify the calculations, design charts are developed. A cable with reverse curvature is analyzed using the design charts. It is shown that the fixed-end moments calculated by neglecting the effect of reverse curvature differ significantly from the fixed-end moments calculated by considering this effect. Hence the effect of reverse curvature …


Epoxy Resin Admixture For Concrete, Kuo-Chu Hu Jan 1965

Epoxy Resin Admixture For Concrete, Kuo-Chu Hu

Masters Theses

"This thesis describes laboratory tests on concrete having epoxy as an admixture. Cylinders for compression and elastic modulus tests were cured under two different curing conditions, standard laboratory cure and a simulated job cure. Beams cured under laboratory conditions were tested for flexural strength. Test results show the compressive strength increases with an increase of epoxy content for job curing conditions. However, compressive and flexural strengths of specimens cured under laboratory conditions show a slight decrease. The elastic modulus of concrete containing epoxy also decreases in comparison to ordinary concrete"--Abstract, page ii.


The Prediction Of Mix Design Properties For Dense Graded Bituminous Mixtures, Robert Ernest Weeks Jan 1965

The Prediction Of Mix Design Properties For Dense Graded Bituminous Mixtures, Robert Ernest Weeks

Masters Theses

"The purpose of this investigation was to ascertain the feasibility of interpolating values of the physical properties of a dense graded bituminous mix between known values. Also the effects of limestone mineral filler on the properties of a dense graded mix are evaluated. The variables in this study were mineral filler and asphalt cement. Control mixes were established at 2, 6 and 10 percent mineral filler and experimental mixes were prepared at 4 and 8 percent filler. The aggregate consisted of limestone and was mixed with an asphalt cement of 85-100 grade penetration. Al mixes were tested by the Marshall …


Effect Of Single Stirrups On Reinforced Concrete Beams, Vinodbhai T. Patel Jan 1965

Effect Of Single Stirrups On Reinforced Concrete Beams, Vinodbhai T. Patel

Masters Theses

"This study was made to determine the location of vertical stirrups and also to determine the amount of stirrup-steel required to prevent diagonal cracking. The study is limited to rectangular, simply supported, reinforced concrete beams subjected to a concentrated point load at the center of the span. Five sets, each containing three beams were tested. Two sets were cast without stirrups and the results were used to locate the stirrups for the remaining tests. The other three sets were cast with one stirrup on either side of the central load. Stirrups were of the "U" type and formed form No. …
