Structural Effects On Micellar Catalyzed Reaction Of Hydroxamic Acids, Nop Utrapiromsuk
Structural Effects On Micellar Catalyzed Reaction Of Hydroxamic Acids, Nop Utrapiromsuk
Masters Theses
Introduction
For many years scientists have tried to find a model which resembles a biological system, so that they can use this model for studying biological systems in human and in living organisms. Micelle systems provide the environment to mimic enzyme systems to some degree.1
Soaps and detergents generate micelles. Soaps and detergents have been used as cleansing agents for a long time. Their cleansing properties are related to micelle formation. Actually, soap is simply a mixture of sodium salts of long chain fatty acids, R-COO- Na+, and some detergents are general sodium salts of straight …

The Effects Of Electron-Donating And Electron-Withdrawing Groups On The Alkylation Sites Of Para-Substituted Phenylacetones, Abraham L. Faburada
The Effects Of Electron-Donating And Electron-Withdrawing Groups On The Alkylation Sites Of Para-Substituted Phenylacetones, Abraham L. Faburada
Masters Theses
The dianions of phenylacetone and its para-substituted derivatives were generated using potassium hydride and n-butyl lithium in tetrahydrofuran. Methyl, ethyl, and n-butyl iodides were used to alkylate the dianions. The results of alkulation indicated that C1 is preferentially attacked by the less active ethyl and n-butyl iodides. The results further show that terminal alkylation is enhanced by electron-donating groups at the para-position of the phenyl ring. The results are rationalized in terms of the difference in electron density at C1 and at C3 in the dianion, on the basis of resonance theory. The regio-selectivity of alkylation as …

Paleoecology Of The Spiriferid Brachiopods Of The Silica Shale Formation (Middle Devonian), S.E. Michigan And N.W. Ohio, Darioush T. Ghahremani
Masters Theses
Spiriferid brachiopods of the Middle Devonian Silica Formation in northwestern Ohio and southeastern Michigan show many Features that are useful For paleoecologic interpretation. This study is undertaken to examine and interpret the paleoecology and paleobiology of six spiriferid brachiopods Mucrospirifer prolificus, Mucrospirifer grabaui, Mucrospirifer profundus, Mucrospirifer mucronatus, Paraspirifer bownockeri and Spinocyrtia euryteines. All are very abundant and can be easily collected from quarries in the Silica Formation near Sylvania, Ohio.
Fourteen different morphologic characteristics have been tabulated for all specimens used in this study. These characteristics allow interpretations of the ontogenetic de velopment and ecologic relationships of the six studied …

Shallow Water High-Magnesium Calcite Mud Production And Dispersal, St. Croix, U.S. Virgin Islands, Jonathan A. Fuller
Shallow Water High-Magnesium Calcite Mud Production And Dispersal, St. Croix, U.S. Virgin Islands, Jonathan A. Fuller
Masters Theses
Boiler Bay, on the northeast coast of St. Croix, is 200 m wide, 800 m long, and about 3-5 m. deep. The hay is separated from the open Caribbean by a barrier reef. Winds from the east drive currents westward across a narrow carbonate platform (where they entrain platform-derived carbonate mud) and into the east end of the bay. Longshore currents continue westward through the bay, and the entrained platform- derived suspended load is combined with bay-produced carbonate mud and swept northwestward off the platform after passing through a 6 km complex of bays along the northeastern shore. The suspended …

Determination Of The Rate Of Formation Of Hcn, Mitchell Hull
Determination Of The Rate Of Formation Of Hcn, Mitchell Hull
Honors Theses
Nitric oxide is a major air pollutant arising from fossil fuel combustion, yet the fuel contribution to its formulation is uncertain. Since, in combustion, fossil fuels undergo disintegration before oxidation takes place, the study of the pyrolsis of a model constituent of fossil fuels can shed light on NO formation. The rate of inert pyrolytic disappearance of pyridine and the rate of formation of the principal Nitrogen-containing pyrolytic product, HCN, was studied in an inert atmosphere. The rate constant for the formation of HCN and its temperature dependence were determined.

Analysis Of An Interlobate Boundary In The Wisconsinan Drift Of Kalamazoo County And Adjacent Areas In Southwestern Michigan, Norman A. Lovan
Analysis Of An Interlobate Boundary In The Wisconsinan Drift Of Kalamazoo County And Adjacent Areas In Southwestern Michigan, Norman A. Lovan
Masters Theses
A detailed investigation of selected textural and mineralogical aspects of tills in southwestern Michigan is used to define an interlobe boundary relationship between the Wisconsinan ice of the Lake Michigan and Saginaw lobes. Bedrock underlying the study area contributed little to the bulk composition of the tils investigated. However, morainal development in the study area shows strong correlation with bedrock topography.
In a discussion of the deglaciation of Michigan and the study area, a history of morainal development is reviewed and attention is focused on the reentrant district located in Kalamazoo and neighboring counties. Attempts to delineate tills of the …
