Protein Content Of Grasses At Different Stages Of Growth, G.F. Gastler, A.L. Moxon

Agricultural Experiment Station Chemistry Pamphlets (1943-1944)

The two attached tables indicate the changes in protein content of Western Wheat grass and Blue Green grass at different stages of growth. The values are based on an air dry basis which would be comparable with the moisture content of dry hay. The values, therefore, indicate the approximate protein content of hay made from these grasses if cut at the stages indicated in the tables.

A Study Of The Fischer-Tropsch Synthesis, John E. Dornfeld

Bachelors’ Theses

In Continental Europe, where raw materials are at a premium, it is necessary to synthesize as much as possible. Hydrocarbons and their oxygenated derivatives are important for "everyday" life. When importation costs of raw materials are high, synthesis is necessary provided it can be done cheaper. The Fischer-Tropsch process is the answer for the needs of synthetic hydrocarbons and their oxygenated derivatives.

The purpose of this thesis is to obtain hydrocarbons and their oxygenated derivatives by the Fischer-Tropsch process in the wax range. From the literature it appears that no work in the industrial field is being done in the …

A Cytolocical Study Of The 4th Chromosome Of Eyeless Drosophila, Joyce Ruth Soelch

Bachelors’ Theses

In Drosophila Melanogaster the recessive gene for eyeless and its normal allelomorph, which cause in general a redaction of the size of the eye in the adult fly, are situated in the small 4th chromosome. The purpose of this experiment was to make a Cyto- logical study and comparison of the 4th chromosomes of the eyeless Drosophila and the normal plus or wild type to determine whether this recessive gene, located on the 4th chromosome, results in a difference in the number, size, formation, or location of bands.

A Suggested Method For The Measurement Of Unsaturation In Organic Compounds By Means Of A Hydrogen Number, Richard Roberts

Bachelors’ Theses

The measurement of unsaturation in organic compounds are commonly expressed in terms of an iodine number, but as this value is not trustworthy in a number of cases, it has been suggested by earlier worker that an indication of unsaturation could be obtained by the quantitative hydrogenation of a compound and expressing the result in terms of a hydrogen number. Although such determinations have been previously made, usually at elevated temperatures and pressures, it is the purpose of this work to carry out the hydrogenation at room temperature and atmospheric pressure. For purposes of comparison, determinations will be made at …

A Viscometric Determination Of The Diastatic Effect Of Amylase On Starches, Dawn Marie Ehlert

Bachelors’ Theses

Internal friction causes some liquids to flow with less freedom than true solutions of the same density. or with less freedom than water. This is attributed in part to larger particle size and prompts one to propose that when using solutions in which the dissolved substance has not been dispersed and subdivided to single molecular particles that the dissolved particles may be present as com­binations. These combinations may increase to enlarged dimensions with changes in temperature, density. electric charges. etc. Similar conditions are characteristic o starch solutions. The solutions are colloidal and vary in particle size. In some situations the …

On The Production Of Polyploidy With Paradichlorbenzene, Mary Anne Carey

Bachelors’ Theses

The subject of polyploidy has been of scientific interest for some time. The true nature of the cause of this phenomenon has been disputed ever since its existence was made known. Polyploidy is the condition in which the haploid number of the chromosomes, contained within the nucleus, is multiplied so that there is a higher number of chromosomes present than there is in the typical diploid cell of that particular plant or animal. The diploid number of the chromois known as 2n, therefore, higher multiples would be referred to as 3n, 4n, 8n etc. Some plants or animals have one …

Polyhydroxyamines, John Wotiz

Master's Theses

"The industrial growth of aliphatic chemistry, which has constituted one of the outstanding advances of recent years, has been almost entirely in the field of hydrocarbons and their simpler chlorine and oxygen derivatives… Representative of the aliphatic amines, possibly only the methyl, amyl and ethanol amines may be said to have been commercially available. And yet the field of aliphatic nitrogen chemistry possesses the greatest variety of known aliphatic compounds; there are at least several nitrogen analogs of each oxygen compound, often more stable, more definitely characterized, and more reactive chemically." Relatively few aminoalcohols, especially polyhydroxyaminoalcohols have been prepared. Due …

Micro-Density Determinations Of Liquids, Rachel L. Horowitz

Bachelors’ Theses

Recent developments in the field of microchemistry have aroused the necessity of accurate micro-methods for density determinations. Such methods have been developed by various investigators and some of them found their application in re­ search and industry, wherever the saving of material and time was an essential problem.

The purpose of this work is to compare all the methods of micro-density determinations found in literature, check their accuracy and simplicity and find their limitations and advantages.

The Effect Of The Ph On The Viscosity Of Various Gelatin Solutions, Theodore C. Kraus

Bachelors’ Theses

Tremendous research has been done in recent years In the field of the protein colloids. Our small, but nevertheless important knowledge of the protein colloids is due to such eminent investigators as Loeb, Kruyt, Freundlich, and Hardy, to name only a few. They have presented to the scientific world valuable experiments and reports of their work. However, much remains to be accomplished in spite of their achievements. The fact that the whole of the organic life processes concerns Itself with colloidal phenomena, particularly the reactions of large aggregates of protein particles, is indicative that the field is widespread in its …

Preparation And Properties Of Diethylene Glycol Fumarate Resin, Marian Sargent

The Influence Of Gelatin On The Ph Of Acids And Bases, Beverly Terwilliger

Bachelors’ Theses

The purpose of this thesis is to determine how gelatin behaves in the presence of various acids and alkalis. It is possible to titrate gelatins with acids and bases and thereby determine the relation of the pH of the solution to the amounts of acid or base combined with the gelatin. If the results are plotted, a titration curve is obtained, the value of which gives the acid and base combining properties of a certain gelatin.

A Chromium Plating Bath Containing Sodium Benzenesulfonate Instead Of Sulfuric Acid, Edward Burleigh

Bachelors’ Theses

At the present day chromium plated articles are saving the country many tons of badly needed metals. The beautiful, bright,luster that chromium has is no longer the prime quality that makes its use so extensive. Today its extreme hardness has taken the foremost place. Parts worn by use and re-claimed with chromium, not only wear longer than the original ones· but they also save valuable metal and time put into new ones. New articles plated with chromium have increased life, and thus the time and metal needed for replacement is greatly reduced.

The present chromium plating baths containing sulfuric acid …

The Cleaning Action Of Detergents And Soaps On Printer's Ink And Lubricating Oils, Daniel David Holzman

Bachelors’ Theses

During the past few years, industry has developed a steadily increasing interest in certain new types of synthetic organic compounds.

Industry devoted to the cleaning of textiles has found the removal of printer's ink and lubricating oils a tedious operation.

There has been developed and perfected a series of synthetic materials which successfully meet modern needs.

The detergents, in general, have some or all of the following properties: wetting-out, dispersing, emulsifying, penetrating, and cleaning.

There seems to be a need to investigate some of these new detergents for commercial cleaning purposes.

A Study Of The Electrolytic Reduction Of Pyrrole, Don Richard Strehlau

Masters Theses

"A review of the chemical literature has shown that electro-organic methods compare favorably with purely chemical methods for certain syntheses belonging to the following general classes of reactions: coupling, oxidation, reactions with halogens, and reductions. Electro-organic methods have been used most successfully in synthesis by reduction. The chief advantage is using electrolytic reduction in preference to a chemical one is that it offers a more exact control of conditions, and consequently should give a higher yield and a purer product. The advantages of the means of reduction suggested an investigation of its use in the synthesis of hydrogenated products of …
