An Analysis Of The Bourbeuse River As A Source Of Concrete Aggregate., David John Lexa

Masters Theses

"This thesis represents a study made to evaluate the sand and gravel deposits of the Bourbeuse River as a source of concrete aggregate. The Meramec River has long been a major source of aggregate in Missouri; however, proposed dam construction will limit the quantity available for exploitation. The Bourbeuse River, a tributary of the Meramec, was chosen for evaluation as an alternate source.

The study was conducted in two parts: an estimation of available quantity; a determination of the quality of the material. Quantity of material was estimated through an analysis of drill logs, correlated with the results of basic …

Heavy And Alkali Metal Content Of Surface And Ground Waters In The Joplin Area, Missouri., Edwin Joseph Garrison

Masters Theses

"Over 50 water samples were collected in the fall and spring from springs, streams, lakes and selected water wells within a radius of six miles from the population center of Joplin, Missouri, which lies within the formerly active Tri-State mining district. The samples were analyzed for Ca, Mg, Na, K, Cu, Pb, Zn, Cd, Fe and Hg. Water well samples represent deep (Cambrian-Ordovician) and shallow (Mississippian) rock sources. Statistical evaluations of the data were conducted to help delineate the patterns and causes of metal variations.

The Ca, Mg, Na, K, Zn and Fe concentrations, listed in descending order of abundance, …

Two-Dimensional Radiative Transfer In Semi-Infinite Isotropically Scattering Medium., Thomas Lee Linsenbardt

Masters Theses

"Two-dimensional radiative transfer in a semi-infinite medium has been investigated. The medium was considered to be homogeneous, absorbing, non-emitting, and isotopically scattering. Cosine, step, and finite strip variations of collimated and diffuse incident radiation were considered. Collimated incident radiation was restricted to lie in planes perpendicular to the direction of its spatial variation.

Expressions for source functions, fluxes, and intensities at the boundary and inside the medium were obtained by assuming cos foe varying incident radiation. This assumption allowed the two-dimensional problem to be reduced to a one-dimensional integral equation for the source function. This integral equation vias transformed into …

Liquid Metal Heat Transfer In Longitudinal Flow Along A Cylinder And Flat Plate., Marvin Eugene Lohmann

Masters Theses

"In this investigation an analytical study is performed to determine the effect of axial heat conduction on laminar forced convection for longitudinal flow of liquid metals along a horizontal cylinder and a flat plate. ii

The flow and thermal boundary layers for the problems under consideration do not admit similarity solutions, the non-similarity arising from the transverse curvature; ε = (4/R) (vx/u _∞) ^½ of the cylindrical surface and from co the effect of the axial heat conduction expressible as Ω = 1/Pe_x , where Pe_x is the local Peclet number. The governing conservation equations along with …

Mercury Distribution In A Massive Sulfide Ore Deposit At Balmat, New York, David Ray Jessey

Masters Theses

"Ore samples consisting of diamond drill core and mine samples, collected from several Balmat ore bodies, were analyzed for their mercury content. The average contents in these ore bodies were found, in ppb, to be: Upper Gleason, 829; Middle and Lower Gleason, 504; Loomis, 546; Fowler, 195; No. 1 Zone, 37; Sylvia Lake, 59; No. 2 Mine, 5. If all of the mercury in these pyrite-sphalerite-galena ores occurs in the sphalerite, then the average sphalerite mercury contents, in ppb, are the following: Upper Gleason, 2490; Middle and Lower Gleason, 2516; Loomis, 2701; Fowler, 1376; No.1 Zone, 384; Sylvia Lake, 408; …

Study Of The Return-On-Investment Surface Of A Small Chemical Plant, Jose Antonio Casas Martinez-Ortiz

Masters Theses

"A study of the return-on-investment (ROI) surfaces for a single reactor chemical plant (Westbrook (8)) with a discontinuous investment function confirms its unimodality in the valid region. In both cases studied, the return-on-investment surfaces rise smoothly to the adiabatic boundary from a singular flow rate below which two of the component flow are not physically realizable. The optimum is located on the adiabatic boundary.

Comparison with these surfaces shows that using linear regression to obtain the parameters for an algebraic simulation of investment does not yield ROI values acceptably near the optimal. However, an heuristic approach, which assumes that minimizing …

Two-Dimensional Radiative Transfer In A Finite Scattering Mediu, James Warren Koewing

Masters Theses

"Exact formulations are presented for the source function, intensity and flux for a two-dimensional, isotropically scattering medium of finite thickness. Spatially varying collimated and diffuse radiation of the following types are incident on the medium: (1) cosine varying, (2) semi-infinite step, (3) step at the origin, and (4) finite strip. The solutions for the cosine varying collimated boundary condition are used to construct solutions for the other boundary conditions. The two-dimensional integral equations are reduced to one-dimensional equations by separating variables. Through a series of transformations, the one-dimensional equations are put into a form in which the source function, intensity …

A new paramagnetic center with g = 2.0029 is observed, in both n- and p-type silicon after they are heavily implanted (higher than 1017 ions/cm2) with 150-keV argon ions. © 1973 American Institute of Physics.

Properties Of Microwave Cavities Containing Magnetic Resonant Samples, Kathy A. Rages, Robert E. Sawyer, Edward Boyd Hale

Physics Faculty Research & Creative Works

Properties of TE011 cylindrical, microwave cavities containing cylindrical samples of various radii and dielectric constants are calculated. The properties considered are the resonant frequency, quality factor (Q), relevant magnetic filling factor for spin transitions (ε), and a signal sensitivity factor (Qε) for a lossless sample. Sample sizes range from zero radius to full cavity radius with some experimental data on less than full length samples. The choice of dielectric constants ranges from one to sixteen. The data are presented in dimensionless form since they will be of use to other ESR experimentalists. It is shown that use of large samples …

The Internal Chemical Shift. A Key To Bonding In Aromatic Molecules. I. Internal Shift Correlations, Donald W. Beistel, Holger E. Chen, P. J. Fryatt

Chemistry Faculty Research & Creative Works

The study of proton shift behavior in nine families of disubstituted benzenes has provided quantitative correlations of internal and meta shifts among all families. The equations of correlation are useful in the prediction of shifts to an error of 0.015 ppm. The studies demonstrate shift additivity for the 4-substituted halobenzenes and suggest a chain rule relationship for substituent effects in those compounds. For that reason, previous theories of substituent interactions involving inductive and resonance contributors appear incorrect when applied to proton shift data. In decreasing order of up field shift at the ortho protons the substituents studied include N(CH3)2, NH2, …

Buckling Of Diaphragm-Braced Columns Of Unsymmetrical Sections And Application To Wall Studs Design, Amir Simaan, George Winter, Teoman Peköz

CCFSS Library (1939 - present)

Lateral bracing has a significant effect on increasing the buckling load of compression members. In the case of wall stud construction, such bracing is provided by wallboards directly attached to the stud along its length and results in increasing the load carrying capacity significantly. The objective of this investigation is to study the behavior of singly symmetric sections braced by shear diaphragms and to apply the theoretical findings verified by experimental results to the design of wall studs. In the present investigation the shear rigidity as well as the rotational restraint of the diaphragm are considered. Using an energy approach, …

Velocity Distribution Versus Sediment In The Missouri River, Glendon Taylor Stevens, Terence E. Harbaugh, Paul R. Munger

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

Analysis of the large quantities of velocity and sediment data gathered on the Missouri River has not been undertaken in the past due to the heavy workloads of U.S. Army Corps of Engineers staff. The need to undertake this effort has long been recognized by both the Kansas City District and the Omaha Division. As a result of this need, the Kansas City District, Corps of Engineers, entered into a contract with the curators of the University of Missouri in September 1972. Dr. G. T. Stevens of the University's Rolla campus will be the principal investigator and will perform data …
