The Effect Of Ph On Phase Reversals Of Protein-Stabilized Emulsions, Samuel Arthur Bradford
The Effect Of Ph On Phase Reversals Of Protein-Stabilized Emulsions, Samuel Arthur Bradford
Masters Theses
"The phase reversal of an emulsion from a system in which oil droplets are dispersed in a water medium to a system in which water droplets are dispersed in oil is dependent upon the interfacial characteristics of the liquids and the emulsifying agent being used, as well as the volume ratio of the two liquid phases. A preliminary investigation at this institution has indicated a possible relationship between phase reversal and the isoelectric point of gelatin used as the emulsifying agent. Since the properties of proteins vary so greatly with the hydrogen ion concentration, particularly near their isoelectric points, research …

"Definition Of The Study. The study consists of an investigation of the variation in the temperature of formation of sphalerite on the 500 and 1500 ft levels of the Balmat zinc deposit at Balmat, New York. A subsidiary investigation was performed on the use of x-ray fluorescence as a means of chemical quantitative analysis. Twelve samples of sphalerite from the 500 ft level and 13 samples from the 1500 ft level were analyzed for atomic percent iron content by measuring Zn/Fe x-ray fluorescent ratios. The x-ray fluorescent ratios were standardized by ''wet" quantitative analysis. The results of the analyses are …
The Effect Of Metallic Naphthenates On The Oxidation Of Linoleic Acid, David Elliott Troutner
The Effect Of Metallic Naphthenates On The Oxidation Of Linoleic Acid, David Elliott Troutner
Masters Theses
"It has been known for many years that certain metallic soaps catalyse the drying of oils. A great deal of information is available concerning the use of these soaps, but there is little knowledge of the actual manner in which the soaps catalyse drying. As the drying is known to be an autoxidation reaction, it is generally believed that the soaps must affect the oxidation of the oil in some way. The work described in this thesis was undertaken to gain some knowledge of the mechanism of the catalysis, and to correlate the effect of the soaps on the drying …

Pre-Cambrian Geology Of Washington County Area, Missouri, Gordon Blair French
Masters Theses
"The Problem.
Washington County, Missouri contains a limited number of outcrops of pre-Cambrian igneous rocks, the majority of which are in the extreme southern part of the county. The known association of lead ore with buried or partially buried pre-Cambrian igneous knobs and ridges in this part of Missouri has led the St. Joseph Lead Company to prospect in areas known to contain these features. In its exploration program, the St. Joseph Lead Company has drilled a number of prospect holes which have encountered other occurrences of pre-Cambrian igneous rocks within the limits of Washington County. This drilling, correlated with …

Flight Path Of Least Time, Robert Katz
Flight Path Of Least Time, Robert Katz
Robert Katz Publications
A problem which one might assume to be of considerable practical interest, but certainly a problem to arouse the curiosity of the undergraduate student, is the problem of determining the most economical flight path of an airplane in the presence of known winds. In general one must assume that the wind system between source and destination is a complex one involving circulation about several centers with winds of variable speed and direction. The geodesic between source and destination is clearly not the flight path of least time in the presence of winds, nor is a cursory examination of a weather …

A Procedure For The Estimation Of Total Radioactivity In Water, Kenneth Vergil Marsh
A Procedure For The Estimation Of Total Radioactivity In Water, Kenneth Vergil Marsh
University of the Pacific Theses and Dissertations
One of the essential duties of the State of California Department of Civil Defense in times of nuclear weapon attack will be radiological monitoring. The workers in this field will operate from a mobile laboratory truck, equipped with radiation counters and meters, but containing only the simplest of chemical equipment. One of their main problems will be the determination of the total amount of radioactive material, especially fallout of fission products, in a water sample. As yet no method of analysis both simple and rapid enough for application to mobile operation has been developed.

Tannin Content Of English Walnuts : Thesis ..., Joseph G. Natoli
University of the Pacific Theses and Dissertations
Present methods for the production of leather from animal hides still depend from the most part on the use of natural tannin extracts. During the year, 1952, the amount of natural tannin extracts used by the leather industry was 560,452,119 pounds as compared to 35,793,000 pounds of synthetic tanning materials. It is not as yet possible to produce synthetic materials as economically as the natural extracts; the result being that there is still a very great demand for natural tannin extracts. The need for finding new domestic sources of tannins is apparent when the amounts of domestic and imported extracts …

Some Uses Of An Oscilloscope In High School Physics, John Ray Bolte
Some Uses Of An Oscilloscope In High School Physics, John Ray Bolte
Dissertations and Theses @ UNI
Use of the cathode ray oscilloscope in the high school physics class has, in many instances, been overlooked by the high school physics teacher as a means of increasing the student's understanding of certain electrical phenomena. In many cases, the teacher may not be well acquainted with the use of an oscilloscope and, very often, the teacher may feel that the cost of such an instrument is beyond the limits of the typical high school science budget.

Chemistry and Chemical Biology ETDs
The search for the carcinogenic factor present in crude oil tar fractions was begun around 1915. With the observation that the high-boiling, most carcinogenic fractions exhibited fluorescence spectra similar to those of many polycyclic aromatic hydrocarbons, several synthetic hydrocarbons were tested (1) on mice by skin painting techniques. Tumors were produced by 1,2,5,6-dibenzanthracene (I), 3'-methyl-1,2,5,6-dibenzanthracene (II) and 6-isopropyl-1,2-benzanthracene (III). One of the most widely used synthetic hydrocarbon carcinogens at the present is 1,2,5,6-dibenzanthracene.

Some Aspects Of The Chemistry Of The Hydroquinoxalines Unsubstituted On The Nitrogen Atoms, Evan L. Allred
Some Aspects Of The Chemistry Of The Hydroquinoxalines Unsubstituted On The Nitrogen Atoms, Evan L. Allred
Theses and Dissertations
A search of the literature revealed that almost nothing is known concerning the class of compounds known as decahydroquinoxalines. Since this posed a problem involving a search for a systematic synthetic method of general application as well as a method for establishing the characteristic class and individual properties, a research project under the guidance of Dr. H. Smith Broadbent was initiated. Of particular interest aside from matters of purely chemical interest was the recognition that the hydroquinoxalines possess obvious structural similarities with atropine and other well-known drugs which have valuable application as hypotensive agents, analgesics, spasmolytic agents, parasympathetic depressants, antihistaminics, …
Acidic Properties Of Clay Minerals And Alumina, Kenneth H. Anderson
Acidic Properties Of Clay Minerals And Alumina, Kenneth H. Anderson
Theses and Dissertations
Acidic properties of dialyzed alumina and representative clay minerals were studied by performing titrations with various bases. For the first group of experiments the titrations were made in a water system using KOH and NaOH. For this study in a water system the experimental data includes individual cationic activities as well as pH values. Adsorption of the cations was adequately described over a pH range of 5-11 by the equation 1-θ/θ ⋅ aNa+ ⋅ aOH- = 1/K'3 [aOH- + KW/K'2 + 1/K'1], in which θ represents the fraction of the total sites that have reacted. Thermodynamic constants K'3 and K0= …
The Effect Of Ferrous And Ferric Ions On The Conversion Of Malate To Pyruvate By A Cell Free Extract Of Pigeon Liver, Keith Erwin Richardson
The Effect Of Ferrous And Ferric Ions On The Conversion Of Malate To Pyruvate By A Cell Free Extract Of Pigeon Liver, Keith Erwin Richardson
Theses and Dissertations
Recent investigations on the crude pigeon liver extracts have shown the presence of an enzyme which catalyzes the oxidative decarboxylation of malate to pyruvate and carbon dioxide. The name malic enzyme has been given to this enzyme to distinguish it from malic dehydrogenase. Under aerobic conditions the addition of ferrous sulfate resulted in inhibition of the action of malic enzyme. Subsequent investigation showed that the inhibition obaerved was not due to ferrous ions, but due to ferric ions which were contaminating the ferrous sulfate. It was also shown that under aerobic conditions ferrous ions were rapidly oxidized to ferric ions. …

A Study Of The Chelation Of 1,3-Bis (Tris (Hydroxymethyl) Methylamino) 2-Propanol With Iron (Iii), Jane Bell Grinnan Gladding
Master's Theses
The element Iron is so important that a major era of history bore its name. Its magnetic and metallic properties have long been studied and used. It is also well known that iron. is the cental element in the oxygen-carrying compound hemo globin and therefore essential to life. Its biological importance is also evidenced by its presence in the cytochrome oxidases . These important biochemical compounds are iron chelates
Fundamental research with iron chelates may therefore shed light on the operations of certain enzyme systems, drugs and poisons. Analytical chemistry and the dye industry have used chelate compounds for many …
