Introduction
The traditional philosophy that a college-or a university is an exclusive institution in which only highly selected individuals receive a concentrated training in the traditional liberal arts no longer exists. In America, for instance, as early as 1870, Harvard, the colonial college with a narrow curriculum, was transformed rather rapidly into a modern university with many new subjects and the elective system (Garrett, 1949). Also, since 1642, when the first entrance requirements were instituted for American higher education, a continuing debate has developed over what constitutes a sound curriculum for education. There are those who …

Electroless And Chemical Metal Deposition On Human Tooth Enamel., Richard Doyle Christie
Electroless And Chemical Metal Deposition On Human Tooth Enamel., Richard Doyle Christie
Masters Theses
"Initial investigations have confirmed the feasibility of depositing an adherent metal film onto tooth enamel. Such films might be used as pit and fissure sealants in preventive dentistry, with denture or orthodontic work, as an intermediate substrate with various organic or inorganic restorative materials, or other such areas. The process employs chemical solutions containing ions of the metal to be deposited and suitable reducing agent solutions.
To date, metallic copper and silver films have been plated onto teeth in vitro. The deposits are quite adherent and appear to exhibit the conductivity, crystal structure, luster, hardness, and other chemical and physical …

All ETDs from UAB
Calcium complexes of polysaccharides that contain D-glucuronate residues have been implicated in such biological processes as calcium storage, calcification, and calcium-dependent cell-cell adhesion. In 1957, Farber, Schubert and Schuster investigated the binding of sodium, potassium, and calcium cations to chondroitin sulfate polyanions.

The Current Status Of The Limnology And Bottom Fauna Of Lakes West And East Okoboji, David D. Gale, Everette E. Drevs, Michael P. Gross
The Current Status Of The Limnology And Bottom Fauna Of Lakes West And East Okoboji, David D. Gale, Everette E. Drevs, Michael P. Gross
Proceedings of the Iowa Academy of Science
Lakes West and East Okoboji, Dickinson County, Iowa, were the site of a 1970 summer investigation on the density and diversity within the macroscopic bottom organisms, physical and chemical measurements of the water and substratum chemistry study. These data on Lake West Okoboji were compared with a 1918 and 1950 study of the macroscopic bottom fauna, water analyses dating from 1934, and oxygen and temperature data from as far back as 1915. The sparse species composition of the bottom fauna has remained unchanged; however, pollution indicator tubificid worms have increased in density. Water analysis, oxygen, and temperature data are little …

Groundwater Of The Spiritwood Lake Area, Stutsman County, North Dakota, Frank J. Schulte
Groundwater Of The Spiritwood Lake Area, Stutsman County, North Dakota, Frank J. Schulte
Theses and Dissertations
The Spiritwood Lake study area is in a generally undulating to rolling glacial plain 17 miles north and east of Jamestown, North Dakota. Spiritwood Lake is about 50 feet below the surface of the bedrock plain in a former melt-water channel. In the study area, glacial drift unconformably overlies the Pierre Shale, the youngest pre-Pleistocene sediment. The boundary between the two units is marked by a zone of shattered Pierre Shale. The top of this shattered zone forms a plain of moderate relief which probably was the preglacial surface of the study area.
Two large valleys can be distinguished in …

On The Mechanism Of The Diels-Alder Reaction--Dimerization Of Trans-Phenylbutadiene, Michael Ward Mcnicholas
On The Mechanism Of The Diels-Alder Reaction--Dimerization Of Trans-Phenylbutadiene, Michael Ward Mcnicholas
Dissertations and Theses
The Diels-Alder dimerization of trans-1-substituted butadienes is expected to yield a cyclohexene adduct with the substituents in the 3 and 4 positions cis to one another. This prediction is based on past observations of other Diels-Alder additions. The cis-isomer is the only one consistent with a two-stage mechanism proposed by Woodward and Katz.
In the case of trans-phenylbutadiene, the expected adduct is cis-3-phenyl 1-4-(trans-styry1) cyclohexene. Alder, Haydn and Vogt, however, reported that the corresponding trans-isomer is the dimerization product. There is reason to believe that the observation of the trans-isomer may have been the result of product isomerization during purification. …

Micronutrients And Biological Patterns In Lake Mead, Hasan K. Qashu, Lorne G. Everett, J. S. Carlson, Bureau Of Reclamation
Publications (WR)
Progressive increases in concentration of dissolved solids in the Colorado River water from Lake Powell to Imperial Dam seem to alter plankton dynamics and biological productivity of the river. Also, changes in biological productivity and micronutrients concentrations occur within the same reservoir. Development of a digital simulation model to predict micronutrients concentrations and biological productivity is necessary for diagnosing changes in plankton population and effluent-carrying capacity of the system. The objectives of the study are: (1) to determine trace metal balance at different locations in Lake Mead, (2) to measure biological productivity and conduct plankton population counts at each sampling …
Two Program Processors For The Preparation Of Instructional Materials In Chemistry, Lloyd V. Gayman
Two Program Processors For The Preparation Of Instructional Materials In Chemistry, Lloyd V. Gayman
Dissertations and Theses @ UNI
The use of inductive or inquiry techniques in the teaching of science has been emphasized. A possible technological aid to the inquiry process is the electronic computer. A review of the literature in this area led to the development of two program processors, one to produce simulated experiments, the other to generate problems for student use.
The first processor, SIM/G, can be used to produce tables or charts. Five sample programs were prepared to illustrate the use of the SIM/G processor. Directions for use of the processor have been given. Documentation has included both a complete verbal explanation and a …

Transfusion Problems In Hemolytic Anemias, Ali A. Hossaini
MCV/Q, Medical College of Virginia Quarterly
In this presentation I have attempted to present some of the transfusion problems that face the Blood Bank and the physician treating the patient. I have briefly discussed methods of recognizing the complicating factors, interpretation of their clinical significance, and the proper hemotherapeutic management of such cases. Finally, I hope that this presentation is a convincing thesis for a better understanding of the Blood Bank and its problems, since the patient's welfare is better served when there is a rapport between the clinician and the Blood Bank staff.

Cyclization Studies Involving The Synthesis Of 5-Substituted-1-Naphthol, Clark Keelock Chow
Dissertations and Theses
The γ-o-substituted-phenylparaconic acids were prepared by a method patterned after that of Fuson. These paraconic acids were prepared in good yield. A re-investigation of the Perkin and Fittig methods of preparing γ-phenylisocrotonic acid was carried out without success.
The synthesis of γ-o-halophenylisocrotonic acids by thermal, and catalyzed decarboxylation of γ-o-halophenylparaconic acid, have been carried out in good yield. An effective catalyst, optimum temperature and reaction period of decarboxylation of the γ-o-halophenylparaconic acids have been determined. Infrared absorptions have characterized the γ-o-halophenylisocrotonic acids formed to be in the stable trans form. …
