A State Architecture Notation Specification Of The Electronic Industries Association Rs-232-C Generic Interchange Circuit, Nelson E. Hastings

Masters Theses

The Electronic Industries Association (BIA) RS-232-C recommendation is an interface specification which was introduced in August 1969 and presents a natural language specification of a 25 pin binary serial data interface between a Data Communication Equipment (DCE) and a Data Terminal Equipment (DTE). The exchange of data signals between a DCE and a DTE ultimately provides the means for DTEs to communicate on networks of DCEs interconnected by different transmission mediums possibly over great distances. The exchange of data signals between a DCE and a DTE occurs at an interface via interchange circuits.

In this thesis we will create a …

Quantitative Analysis Of Steroids By 13C Nmr Spectroscopy, Pei Wang

Masters Theses

Steroids are usually analyzed quantitatively by using HPLC with ultraviolet detection and are confirmed by FTIR, GC-MS. Quantitative ¹³C NMR method provide an alternative means to analyze steroids. Chromatographic separation and subsequent identification by match with a spectroscopic data base spectrum is not required for quantitative analysis of mixture components. Instead, equivalent information is obtained by creating subspectra from resonances with equivalent peak areas within a quantitative NMR spectrum. Techniques for eliminating Nuclear Overhauser Enhancement (NOE) effect is described.

Approaches To And Synthesis Of Chalcone Amides, Gregory S. Marczak

Masters Theses

A series of "chalcone" amides have been prepared. These amides are unique in the position of the substituted hydroxy and methoxy functional groups. Early approaches to the synthesis of the amides proved difficult when preparing intermediates from the phenolic substituents. These phenols were then protected to lead to easier formation of the intermediates, and then deprotected to yield the corresponding chalcone amides. The approaches to the preparation of these compounds is presented, along with the physical data used to characterize the chalcone amides.

Identification Of Aromatic Acids As Microbial Metabolites Of Fossil-Fuel Compounds Present In Aquifer Systems, Daniel Michael Tomczak

Masters Theses

The identification and quantitation of aromatic acids as transformation products present in contaminated aquifer systems was studied from selected sites. These acids are formed as microbial metabolites in the oxidative degradation of aromatic compounds. The microbial activity in the subsurface can be coupled to the oxidation of the aromatic compounds and the reduction of specific inorganic indicators. Inorganic indicators identified from the sample sites include the reduced forms of iron, nitrate, sulfate, and dissolved oxygen.

The highest concentrations of the aromatic acids were found in the plumes of the contaminated sites. These concentrations also correlated with specific changes in concentrations …

Using Differential Outcome To Teach Medication Discriminations To Head Injured Adults, Scott C. Votava

Masters Theses

In attempt to replicate the DOE in teaching medication discriminations, the efficiency of differential outcomes and nondifferential outcomes procedures was compared. Additionally, the effects of the differential outcome procedures and nondifferential outcomes procedures upon generalization probes to novel medications were investigated. Finally, the effects of differential and nondifferential outcome procedures on probes to real medications were investigated. The results showed the differential outcome procedure employed produced the desired discrimination more rapidly than the nondifferential outcome procedure. No conclusive statement can be made regarding data obtained in generalization probes or in probes with real medications.

Evidence For Dna Methylation-Sensitive Transactivator Mediated Regulation Of The Expression Of An Epstein-Barr Virus Neutralizing Antigen, Sridhar Chalasani

Masters Theses

DNA methylation has a profound effect on the expression of a number of eukaryotic genes. This study demonstrates that an Epstein-Barr virus (EBV) positive Burkitt's lymphoma cell line, Raji, contains the gene encoding gp350/220 but is not expressed. Frog virus 3 (FV3), an iridovirus, has the ability to overcome the inhibitory effect of DNA methylation. Fusion of FV3-infected cells with Raji cells resulted in expression of gp350/220, suggesting that gp350/220 is regulated by DNA methylation. Further evidence for this hypothesis was obtained by transfecting B95.8 cells with HpaII/HhaI methylated plasmid pLATE-CAT, containing the gp350/220 promoter. Southern blot analyses and a …

Studies Of Silica As A Polymer Support For Regioselective Reactions On Sucrose, Lei Cheng

Masters Theses

Sucrose is a material that has potential for replacing oil as an industrial feedstock, at least in some instances. A major difficulty in utilizing sucrose is the lack of regioselectivity in its reactions due to the many reactive sites on the sucrose molecule.

This research is part of an attempt to study the technique of molecular recognition in an effort to increase reaction regioselectivity. Molecular recognition by template imprinting should be a way to create a material that would "recognize" and bind to sucrose in such a way as to block certain of the hydroxyl groups on the sucrose. The …

Studies Directed Toward The Synthesis Of Germacranolides Via [2+2] Cycloaddition Followed By Ring Expansion/Elimination Of Β-Lactones, Bryan E. Yates

Masters Theses

Exposure of α-trimethylsilyl β-lactones to magnesium bromide or boron trifluoride etherate in diethyl ether solvent resulted in the smooth generation of β,γ-unsaturated acid derivatives in good yield and isomeric purity. It is believed that this reaction occurs via the formation of a stable tertiary carbocation at the γ-carbon resulting from cleavage of the carbon-oxygen sigma bond due to the complexation of the Lewis acid with the ring oxygen atom. Rapid loss of an adjacent electrofuge then furnishes the unsaturated acids. The β-lactone precursors were prepared by a [2+2] cycloaddition of an aldehyde and an alkyl trimethylsilyl ketene. This method was …
