An Index To The Literature On Digenetic Trematodes From Fishes, Richard William Bond Jan 1950

An Index To The Literature On Digenetic Trematodes From Fishes, Richard William Bond

University of the Pacific Theses and Dissertations

The primary purpose of this compilation is to facilitate for pertinent literature in the searches involving digenetic trematodes from fines. The index may be used by the investigator to determine what, Af any, 14torature has appeared concerning the animal or group of animals with which he is working; and the literature is cross-indexed in such a way that it may be approached from the various angles commonly used in trematodes investigations. There are included, for example, an index to hosts, an index to larval stages of development and a partial geographic index to adult trematodes of fishes.


Intermolecular Potential Functions For Liquid Argon And Liquid Mercury, Richard H. Kerr Jan 1950

Intermolecular Potential Functions For Liquid Argon And Liquid Mercury, Richard H. Kerr

Masters Theses

"The purpose of this research is to obtain such intermolecular potential functions for liquid argon and liquid mercury by use of the experimental radial density functions available for these two liquids over a wide range of temperatures. We shall introduce the notion of a correlation between the motions of atoms in neighboring cells in a cell theory of liquid structure, and derive a theoretical radial density function involving the intermolecular potential function for a pair of atoms in the liquid. This radial density function, or as it is frequently termed, the atomic distribution function, applied to the experimental data should …


A Determination Of The Surface Tension Of Bismuth, Cadmium, Tin, And Lead, Edward Mckee Chandler Jan 1950

A Determination Of The Surface Tension Of Bismuth, Cadmium, Tin, And Lead, Edward Mckee Chandler

Masters Theses

"Various methods have been employed for the determination of surface tension including capillary rise, drop weight, maximum bubble pressure, sessile drops on flat surfaces, sessile bubbles formed underneath flat surfaces, and the shape of pendent drops. Each method is subject to characteristic advantages and disadvantages. Only two of these will be discussed. The method of maximum bubble pressure allows the formation of a fresh surface for every bubble but does not permit the study of a given sample over a period of time. The sessile drop in direct contrast, allows the observation of the same sample over any period of …

Factors Influencing The Solubility And Oxidation Of Commercial Iron Pyrites, Neldon Lamont Jensen Aug 1949

Factors Influencing The Solubility And Oxidation Of Commercial Iron Pyrites, Neldon Lamont Jensen

Theses and Dissertations

Studies were made (1) to determine the effect of air and oxygen and verying concentrations in distilled water, on the solubility of iron pyrites; (2) to determine the effect of acid, base and buffer solutions of varying pH; (3) to observe the effect of some oxidizing and reducing agents on the solubility of iron pyrites. These investigations would aid in deciding the possibilities of using iron pyrites as a soil conditioner.


An Investigation Of The Radioactivity Of Oilwell Drilling Fluid, With Depth, Of Wells In The Berland Field Of Rooks County, Milford W. Johnston Jul 1949

An Investigation Of The Radioactivity Of Oilwell Drilling Fluid, With Depth, Of Wells In The Berland Field Of Rooks County, Milford W. Johnston

Master's Theses or Doctor of Nursing Practice

In reviewing the foregoing literature and in consideration of the very important place of the state of Kansas in the nation's production of petroleum, it was thought that possibly a contribution might be made to the general subject of geophysical prospecting for oil by the adoption and execution of the problem proposed by the title of this thesis. Since a similar but more scattered study of this problem had been previously made by Lippert with the use of an electroscope, it was considered worth-while to repeat the electroscopic observations together with Geiger-Mueller Counter observations on a new series of wells …


A Study Of Atmospheric Ozone Near The Surface Of The Earth, Irby Gerald Bowen Jun 1949

A Study Of Atmospheric Ozone Near The Surface Of The Earth, Irby Gerald Bowen

Physics & Astronomy ETDs

It is the primary purpose of this thesis to describe the method used for measuring ozone at the earth’s surface. There is also a report on a brief series of surface ozone measurements. An attempt is made at a preliminary explanation on the basis of meteorological conditions of the diurnal variations which were found.

Separation Of Cadmium From Zinc In The Purification Step Of The Leaching Cycle, L. C. Powell

Bachelors Theses and Reports, 1928 - 1970

The purpose of this investigation is to determine the effect of the factors listed previously by conducting a series of tests that will indicate the ex­tent to which the purification is influenced by time, temperature, zinc oust size, zinc dust quantity, iron concentration, two stage precipitation, and aeration.


A Study Of The Transformation Of A Twenty-Eight Per Cent Tin Bronze, Perry A. Boukind May 1949

A Study Of The Transformation Of A Twenty-Eight Per Cent Tin Bronze, Perry A. Boukind

Bachelors Theses and Reports, 1928 - 1970

In this investigation, attention is directed to the phases covered by a 28 per cent tin alloy. When the investigation was started, consideration was given to the possibility of making a Time - Temperature - Transformation curve for this parti­cular alloy. As the work progressed and further research was carried on, this phase of the work was abandoned.


The Characteristics Of The Electrolyte In The Series System Of Electrolytic Copper Refining, Carl W. Howald Jr. May 1949

The Characteristics Of The Electrolyte In The Series System Of Electrolytic Copper Refining, Carl W. Howald Jr.

Bachelors Theses and Reports, 1928 - 1970

Almost everyone is familiar with the tremendous importance of copper in our everyday life. One of the pro­perties of copper which determines its great usefulness to mankind is its electrical conductivity. This property alone has more to do with the prominence of copper among useful metals then does any other.


Daibase Sill Comanche County, Oklahoma, Jean A. Hardesty May 1949

Daibase Sill Comanche County, Oklahoma, Jean A. Hardesty

Bachelors Theses and Reports, 1928 - 1970

The mechanics of intrusion and the processes involved are becoming of more and more interest to con­temporary geologists, because most of our mineral deposits are associated with igneous intrusions, and unknown-outcropping deposits are thought to be a thing of the past. If, by studying these pro­cesses, we could understand why some igneous masses are barren, while others of similar composition carry economic mineral deposits, geological prospecting for hidden mineral concentration would see a new era.


An Isopach Map And Discussion Of Triassic Strata In Southern Montana And Wyoming, Robert G. Thompson May 1949

An Isopach Map And Discussion Of Triassic Strata In Southern Montana And Wyoming, Robert G. Thompson

Bachelors Theses and Reports, 1928 - 1970

Oil and gas have been found in the Triassic strata of Wyoming. Although the Triassic has not as yet proven to be a large producing horizon it is very probable that ad­ditional oil will be found in Triassic strata in the future, and it is one of the goals at which oil well drillers aim their tools.

The Potash Status Of Utah Soils, Sukhendu Bikas Chaudhuri May 1949

The Potash Status Of Utah Soils, Sukhendu Bikas Chaudhuri

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Potassium is one of the essential plant nutrient elements. It is used by plants in the synthesis and distribution of carbohydrates (25)2 and in the formation of proteins and oils. Potassium also seems to exert many of its effects by influencing enzymatic activity in cells.

Potassium occurs as the monovalent cation on plant cells and undoubtedly exerts important effects upon such phnomona as the permiability of the cytoplasmic membranes and hydration of protoplasma. Plants assimilate potassium either from the soil solution or directly from the exchange complex.
