The Surficial Geology Of Southern Logan County, North Dakota, John W. Bonneville

Theses and Dissertations

Southern Logan County, North Dakota, was glaciated at least three different times during the Pleistocene epoch. Scattered patches of highly weathered iron-cemented drift found in the area of eroded Cretaceous bedrock in southwest-era Logan County are very possibly pre-Wisconsinan in age. Two younger drift sheets of Wisconsinan age cover the remaining portion of the county. One of these drifts, the Napoleon drift, is probably early Wisconsinan, and the other, the Burnstad-Streeter drift, is likely late Wisconsinan in age.

A great diversity in types of glacial topography and individual features is found in southern Logan County. Excellent examples of end moraine, …

An Investigation Of The Formation Constant Of Molecular Silver Chloride Using Ion Exchange Techniques.|Nii.|Pan Investigation Of The Rate Of Precipitation Of Silver Sulfide By Thioacetamide, James W. Pyper

Theses and Dissertations

The first part of this work reports on the investigation of the formation constant of molecular silver chloride using ion exchange techniques. In order to determine the formation constant, it was necessary to develop a method of rinsing the sorbed molecular silver chloride from the resin. It was found that desorption with nitrobenzene would remove the sorbed molecular species. However, the formation constant was not calculated since the nitrobenzene used contained hydrogen ion and chloride ion which removed silver ion as well as the molecular species. In the study of the formation of silver sulfide by the reaction between the …

Early History Of Malad Valley, Glade F. Howell

Theses and Dissertations

The Malad Valley is geographically located in a unique position in the Pacific Northwest. The Bear River and its main affluent, the Malad River, are the only rivers in the Pacific Northwest that drain into the Great Basin, whereas the other streams and rivers of the states of Washington, Idaho, and Oregon empty eventually into the Pacific Ocean. It is also characterized for being the northern end of prehistoric Lake Bonneville, and eventually it was through this valley that an outlet opened to drain the lake. The soil deposits from this lake left a fertile valley, capable of producing most …

The Cytochrome Composition Of Bacillus Subtilis And Bacillus Megaterium, John Harvey Mangum

Theses and Dissertations

A spectroscopic and enzymatic investigation of the cytochromes of B. megaterium and B. subtilis was conducted. Attempts were made to isolate and characterize the individual cytochromes as well as to determine the locale of such activities as cytochrome c oxidase, DPNH oxidase, succinic dehydrogenase, cytochrome c reductase and diaphorse. Only two methods proved effective in liberating the cytochromes; disruption of the cells with sonic osillations and grinding tlhe cells with alumina. These procedures caused a fragmentation of the cell membrane. It was found that the entire cytochrome complement of these two bacteria was bound intimately to particles which most likely …

The Bromination Of 1,1,1-Ethanetriacetic Acid, John A. Gurney

Theses and Dissertations

Essential to the entire field of Organic Chemistry is the nature of the carbon to carbon bond. Our current concepts and guiding principles concerning it are almost solely constructed from aliphatic compounds, certain simple ring species, and aromatic systems. Except for special cases, aliphatic and aromatic types are felt to be mildly strained or free from internal tension while the alicylic small and medium ring compounds are the so-called strained molecules. These strained compounds involve bending back or compression of two of the four carbon bonds from an equilibrium position. Distortions of more complex origin occur in the paracyclophanes and …

The Photoreduction Of Indigo Carmine Flavin Mononucleotide And Diphosphopyridine Nucleotide, By Illuminated Chloroplasts, M. Odell Hobbs

Theses and Dissertations

An investigation was made of the photoreduction of indigo carmine dye and flavin mononucleotide (FMN) by an illuminated sugar beet leaf homogenate in the presence of 2,6-dichlorophenolindophenol dye (DPIP) and ascorbic acid. DPIP and ascorbate were absolutely required for the reaction. Reconstitution experiments indicated a requirement for a heat-labile factor present in the supernatant fluid following centrifugation of the leaf homogenate. This factor activated the photoreduction of indigo carmine more than 20 times. The photoreduction of FMN was activated 2 times by this factor. Studies on the stoichiometry of indigo carmine photoreduction revealed that one mole of ascorbate was photooxidized …
