Characterization Of The Effects Of Biosynthetically Incorporated Tryptophan Analogues In Rat Parvalbumin F102w And Structure-Function Studies Of Tryptophanyl-Trna Synthetase., Mauro. Acchione
Electronic Theses and Dissertations
Fluorescence spectroscopy of tryptophan residues is a valuable tool for dissecting the structure, function and dynamic behaviour of proteins. An important step in method development is the use of tryptophan analogues with unique photophysical properties that extend the utility of intrinsic protein fluorescence. Two difficulties limit the use of these analogues. Their structure, while similar to that of tryptophan, can perturb native protein structure resulting in misfolding or inactivity. There are also problems from an inability of tryptophanyl-tRNA synthetase (TrpRS) to use these analogues as a substrate in the tRNA charging reaction. The tryptophan residue in rat parvalbumin F102W is …

Layered Approach To Persistency Modeling In Object-Oriented Environment., Kamran. Choudhery
Layered Approach To Persistency Modeling In Object-Oriented Environment., Kamran. Choudhery
Electronic Theses and Dissertations
Object persistence is a fundamental feature of any object-oriented environment. Several programming language specifications do not include or discuss any method of providing persistence for objects. Several schemes have been developed for adding persistence in several different programming languages. Some of them require persistent objects to be allocated and treated differently than non-persistent objects, while some others require the programmer to provide vital parts of the persistence mechanism. It is desirable to make the persistence feature transparent, but the nature of object oriented programming makes it difficult. This thesis proposes an approach to build a persistency layer in an object …
Technologies Of Governance: The Convergence Of Risk And Discipline In An Open Custody Facility For Young Offenders., Dale A. Ballucci
Technologies Of Governance: The Convergence Of Risk And Discipline In An Open Custody Facility For Young Offenders., Dale A. Ballucci
Electronic Theses and Dissertations
This paper expands current debates on governance within corrections by examining the relationship between rationales and technologies deployed in the governance of young female offenders. A detailed examination of formal corrections policies, policy manuals, and interviews with administrators and primary counsellors challenge the notion that there is a pre occupation with risk in contemporary penal practice and that risk rationales and technologies have displaced discipline as dominant strategies of governance. It is certainly true that the logic of risk is present in both discourse and practice and that their development has added a new dimension to the governing process. However, …

Woman, Not Womb: A Feminist Examination Of In Vitro Fertilization., Janice Hemani. Perera
Electronic Theses and Dissertations
Women's choices over their reproductive parts and destiny (as some may call it) were controlled in the past by men, and while many believe that reproductive power presently resides in the hands of women, I believe that this is not the case. In this thesis I will examine the reproductive technology, in- vitro fertilization (IVF) and its effects on women. My intention is to bring to the forefront the social factors responsible for a woman's desire to bear children, and how these factors shape and determine her happiness and self-worth. I believe that the medical description and treatment of infertility …
