The Content Of Essential Amino Acids In 1950 Alfalfa Hay Grown In Utah Soil Treated With Different Fertilizers, Adriana Lanting Kunkel

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Application of fertilizers to soils to increase production yields has raised questions concerning the effect of fertilizer on chemical composition of plants. With the development of accurate, sensitive microbiological methods for the determination of amino acid in protein, speculations concerning amino acid content have been supplanted by acquisition of facts.

The effect of the different fertilizer applications on alfalfa yield has been discussed by Jones, et al (5). Also, some work has been done to determine the effect different fertilizers might have on the amino acid content of plant material. Some values (1,3,12) have been reported for the amino acid …

The Synthesis Of 10-Methyl-3, 4-Benzpyrene And 8,10-Dimethyl-3, 4-Benzpyrene, Jules Adelfang

Chemistry and Chemical Biology ETDs

In 1953 Cook, Hewett, and Rieger found a highly carcinogenic hydrocarbon in coal tar. By a variety of solvent extraction methods, fractional distillation, and crystallization several pure hydrocarbons were isolated from the crude pitch. Two new pentacyclic aromatic hydrocarbons were isolated and since only small quantities of them were available it was decided to ascertain their structures by synthesis instead of degradetive experiments. The hydrocarbon samples were obtained with great difficulty from two tons of crude pitch. The problem was simplified since ten of the possible fifteen pentacyclic hydrocarbons were known. From certain similarities of these hydrocarbons to perylene its …

The Electrolytic Reduction Of Osmium Tetroxide In Perchloric Acid Solution, Donald Lloyd Brunner

University of the Pacific Theses and Dissertations

This is a study involving some of the chemistry of osmium tetroxide in perchloric acid solution. The research was originally instigated from a seminar report on the ruthenium III thiocyanate complex ion which was studied in perchloric acid solution. The seminar report given by Craig Townsend discussed how a spectrophotometric study by Yaffe and Voight (1951) was made of the ruthenium III thiocyanate complex ion, Similar possibilities were recognized as being possible in attacking the problem of an osmium thiocyanate complex or complexed. Some of the chemistry involved in the study of the ruthenium III thiocyanate complex will be discussed …

A Colorimetric Coulometer, Clayton C. Roth

Master's Theses

In the study of many electrochemical processes, such as, surface adsorption on electrodes, a simple, rapid, and relatively accurate coulometer that will measure .01 to 1.0 coulombs, would be extremely useful. This project was commenced to investigate the feasibility of an entirely different approach for coulometric analysis for application in this range.

This new type of coulometer utilizes a colorimeter for determining the amount of coulombs passed through coulometer cell. Consequently, any electrode process which of its own nature is color-producing, or a process which, in turn, can actuate a color indicator, is a potential reaction for this colorimetric couloumeter.

A Statistical Evaluation Of Various Determinations Of Germanium, Kenneth William Bartz

Bachelors’ Theses

Germanium first came to the author's attention under the heading of "A Study of the Excited States of Matter." The various and diverse, not to mention peculiar properties of this element aroused my interest. But upon further studying of this unusual element my concern switched from its properties to the methods of analysis. It is the purpose of this paper to discuss and correlate the numerous and varied analytical determinations. However, actual determinations are limited to instrumental procedures only.

For the evaluation and interpretation of the date, Statistical Analysis is used. The author's qualification in Statistical Analysis include a year …

Mechanism Of Adsorption Of Cations By Silicate Minerals, Milton Glen Armstrong

Theses and Dissertations

Adsorption of cations by clays has been a subject of investigation for many years. Many proposals have been advanced to explain this process of adsorption. Two proposals have been prominent in recent years. The Marshall "charged lattice" theory attributes adsorption of cations by clays to an electrostatic attration of the clay particles for cations. This charge on the clay particles is attributed to various isomorphic substitutions in the lattice of the clay which result in an unbalanced charge on the particle. This isomorphic substitution can take place either in the silicon-oxygen tetrahedra of the silicate structure or with the aluminum …

Szilard-Chalmers Reactions, Anita Camilli Mewherter

Honors Theses

Since discovery of radioactivity at the turn of the century, the use of radioactive isotopes has become increasingly significant to research in the fields of chemistry, biology, botany, and medicine. An important use of these radioactive isotopes is the tracer or indicator method. For example, a portion of radioactive potassium may be added to a sample of of stable potassium to be studied. The fact that a given isotope is radioactive does not, in most cases, affect its chemical properties. The presence of the active isotope allows the potassium now to be followed through a chemical or biological process. This …

An Investigation Of Some Changes In The Chemical Composition Of Arterial Tissue Which Correlate With The Development Of Arteriosclerosis, Richard Dee Strickland

Chemistry and Chemical Biology ETDs

Arteriosclerosis is one of the major health problems confronting people of middle and advanced age. The disorder, commonly called "hardening of the arteries", is a contributing factor in more deaths than any other ailment.

The profound alteration in the physical properties of arteries which comes about as a result of the sclerotic process suggests that equally important changes may take place in the chemical composition of the arterial tissue.

Studies In The Cinnoline Series, David B. Cox

Chemistry and Chemical Biology ETDs

Recent work by Castle and Kruse (16) has partially elucidated the range of reactivity of the chlorine atom in the compounds 4-chlorocinnoline and 4-chloro-6,7-dimethoxycinnoline. Condensations between the chlorinated cinnolines and certain phenylacetonitriles were found to proceed readily; however, condensations with compounds of the malonic ester type were unsuccessful. It was found that hydrolysis of the condensation product obtained from 4-chlorocinnoline and phenylacetontrile by hot 60% sulfuric acid caused decarboxylation of the intermediate acid, the final product being 4-benzylcinnoline. This compound has a formal resemblance to the basic ring structure of papaverine.
