All Graduate Plan B and other Reports, Spring 1920 to Spring 2023
The student council idea is now widely accepted in secondary schools in the United States; its full potential in contributing to the education and lives of students has not been realized fully in a great many instances.
The student council is a dynamic movement and because it is dynamic it is capable of change to meet new conditions. Hence, it cannot remain basically the same year in and year out. The changing dimensions of the student council can be realized only if students, faculty and principals work at it.

Influence Of A Soil Microfloral Crust On Hydrologic And Chemical Properties Of Soils In Southeastern Utah, Walter L. Loope
All Graduate Plan B and other Reports, Spring 1920 to Spring 2023
Cryptogamic soil crusts within the Colorado Plateau were studied to determine their effect on infiltration rates, potential sediment production, permeability, and several chemical properties of the soil. Six different crust stages were identified. Undisturbed soil cores were used to determine intrinsic permeability under three treatments and disturbed soil samples were analyzed for pH, percent organic matter, soil texture, Ca+Mg content and total conductivity.
It was found that the cryptogamic crust had little effect on soil chemical properties. Analysis of undisturbed soil core data indicates that high cryptogamic cover tends to decrease intrinsic permeability; this effect was reinforced when cores were …

The Use Of Soil-Cement As A Highway Material, Vongchai Jarernswan
All Graduate Plan B and other Reports, Spring 1920 to Spring 2023
Soil-Cement is not a new material; its low cost but high quality make it well-known and the use of this material for highway, dam, and airfield purposes increases every year. The origin of the idea of mixing soil and cement to produce a structural material has not been definitely established; informal records show that mixing soil and cement was tried in Iowa, Ohio, Texas and probably in other places by 1920 (1). Since the first controlled soil-cement construction was carried out near Johnsonville, South Carolina in 1935 (2), soil-cement has been considered a valuable engineering material. It is now an …

Essential Tyrosine Residues In Calf Liver Uridine Diphosphoglucose Pyrophosphorylase, E.C. 2.7.7.9., Robert Carl Bachmann
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The catalytic necessity of tyrosine residues in uridine diphospho- glucose pyrophosphorylase [E.C. 2.7.7.9] was investigated. Chemical modification of the pyrophosphorylase by N-acetylimidazole indicated that tyrosine residues were essential for activity. Approximately 23 of 112 tyrosines per molecule of 475,000 Daltons could be 0-acetylated. Solvent perturbation difference spectroscopy supported this number of exposed tyrosine side chains and in conjunction with chemical modification indicated that at least 11 to 12 tyrosyl residues per protein molecule are fully exposed. it her subst rate, uridine t riphosphate or uridine diphosphoglucose, afforded significant protection against inactivation by N-acetylimidazole.
