The Effects Of Certain Salts Upon The Saccharogenic Activity Of Three Typical Enzymes, George F. Gastler

Electronic Theses and Dissertations

In a previous investigation carried out in these laboratories, Moxon and Franks (1), have shown the toxicity of sodium salts of selenium, vanadium, arsenic and tellurium toward the production of carbon dioxide during yeast fermentation of glucose. The toxicity of the salts occurred in the order given. In the same investigation (1), it was shown that sodium sulfide and sodium sulfite exert an accelerating effect.

An Investigation Into The Bromate Method Of Manganese Determination, Ray A. Bunday

Electronic Theses and Dissertations

Throughout the history of research in the science of Chemistry the problem of the quantitative determination of manganese has always been a perplexing one. The results have usually fallen short of the theoretical value and has necessitated the application of an empirical factor(1) which is always undesirable to the true research scientist, if not to the commercial analyst.

Selenium In Proteins From Toxic Foodstuffs, Edgar Page Painter

Electronic Theses and Dissertations

The importance of the selenium problem has been established. Knight (1) in an address before The Association of Official Agricultural Chemists summarized the progress made on the problem, conservatively emphasized its importance, and stressed the need for extensive research. It is a paramount problem not only in South Dakota, but in many other states as well.

Determination Of The Limits And Accuracy Of Potassium Ferricyanide As An Outside Indicator In The Determination Of Iron And A Comparison Of This Outside Indicator With Diphenylamine As An Inside Indicator, Eugene D. Burr

Electronic Theses and Dissertations

In the volumetric course as offered by the Department of Chemistry of South Dakota State College for the spring term of 1931, we experienced difficulties in the methods which we were using for the determination of iron. The general method used was that of Penny's, using an outside indicator of potassium ferricyanide, and titrating with potassium dichromate.

The Alkaloids, Felix F. Barre

Electronic Theses and Dissertations

This thesis, presented for the degree of Bachelor of Science, provides a systematic chemical study of the alkaloids, a class of complex nitrogenous plant substances possessing basic properties. Barre opens by defining the alkaloids and surveying the various systems used to classify them, whether by natural versus artificial origin, chemical nucleus (pyridine, quinoline, or isoquinoline), volatility, or botanical family of origin, and outlines their general physical and chemical properties, including solubility, optical activity, and characteristic reactions with precipitating and color-test reagents.

The thesis details standard laboratory methods for the extraction and separation of alkaloids from plant material, including a step-by-step …

The Development Of Colloid Chemistry, Oscar A. Bouise

Electronic Theses and Dissertations

At first, it was a blur, that had shrouded a great mystery for ages and ages, until some seventy odd years ago. Then came Thomas Graham, who could not satisfy himself with merely viewing a blur as a blur. Being a scientist, he applied his mind experimentally, with the keen precision of any of the eminent astronomers using a telescope, and viewed more clearly this mist which hovered above the horizon . But maybe it was not due time fir the unfolding of the great secret, for Graham's focus only revealed a more complicated mist that had been seen before. …
