Geometric Photoisomer Investigation Of Bilirubin (Z,Z)-Ixα, Robert Howe Walker Iii

Chemistry & Biochemistry Theses & Dissertations

Numerous investigations of bilirubin have been reported in the literature. Correlation among these investigations can not be made because of multiple behavioral changes characteristic of the solubilized pigment. This research was initiated to evaluate bilirubin and its associated isomers in identical chemical environments.

Two different solvent systems were experimentally selected to study chemical behavior of bilirubin and occurring photoisomers. A ternary solution consisting of 1:3:1 chloroform:methanol:water was used exclusively in visible spectrophotometric analyses. Also, a pH 10.00 buffer was utilized. This latter system has successfully been used in spectrophotometric and voltammetric work.

Four different photochemical processes have been detected spectrophotometrically, …

Generic Specifications In Lil And In Ada Via Analogies, George Chester Harrison

Computer Science Theses & Dissertations

We address the problem of .making verifiable specifications in generic program units in the Ada Programming Language*. We illustrate the methodologies of LIL proposed by Joseph Goguen and Justify the use of such a specification languages using analogy programming originally proposed by Nachum Dershowitz. The work in these areas is new and noticeably incomplete. We address our concern about the reusability of Ada software in a programming environment that includes a specification language like LIL. * Ada is a registered trademark of the U.S. Government (Ada Joint Program Office)
