The A-B Signal Detection Theory Model
<p>The purpose of this research was threefold: (1) Present the <em>a-b</em> SDT model as an alternative framework to overcome the limitations of the underlying SDT model and the traditional measures of sensitivity and criterion setting, (2) Provide empirical support to validate the adequacy of the …

Synthesis of Lignans Utilising the Acyl-Claisen Rearrangement: Total Syntheses of (+)-Ovafolinin A, B, (–)-Bicubebin A, B and (+)-Bicubebin C
Lignans are a diverse class of natural plant products which continue to provide new chemical structures as potential biologically active compounds. The recent syntheses of lignans has allowed for the development of new synthetic methods, confirmed or corrected proposed structures for these natural …

Properties of the 3He A-B phase boundary
This thesis deals with various properties of the 3He A-8 phase boundary. First a review of some static properties, the surface energy and Kapitza resistance, is given. Then the symmetry of the interface is discussed. It is pointed out that, due to the presence of the condensate, many symmetries are …

Investigating cofactor transfer for a B₁₂-dependent enzyme
The metallocofactors utilized by enzymes can range in complexity from single metal ions to organometallic cofactors well over 1000 Da. These cofactors enable these metalloenzymes to accomplish a diverse set of unique and challenging chemistry that are critical to core life functions. One of these …

Is Toilet Training As Easy As A B C?
Toilet training is often viewed as a fairly straightforward process. This may be why much of the prescriptive literature available today has not been subject empirical investigation. This study followed twenty-six children through toilet training to investigate five factors that are assumed to be …

Re-engineering a B-tree implementation using design patterns
Software design is a difficult creative task learnt from long experience. Reusable object-oriented design aims to describe and classify designs and design fragments so that designers may learn from other peoples' experience. Thus, it provides leverage for the design process. The evolution of a …

Properties of the Helium-3 a-B Phase Boundary
This thesis deals with various properties of the ('3)He A-B phase boundary. First a review of some static properties, the surface energy and Kapitza resistance, is given. Then the symmetry of the interface is discussed. It is pointed out that, due to the presence of the condensate, many symmetries …

Characterization of the A/B regulon in tobacco (Nicotiana tabacum)
Plant alkaloids are secondary metabolites that may be synthesized in an inducible defense response to herbivory (Baldwin 1999). Genetic engineering of secondary metabolic pathways in plants to enhance or reduce metabolite production is limited by the current understanding of these pathways and …

B phase nucleation and A-B interface dynamics in superfluid 3He
This thesis deals with the theory of the primary nucleation and subsequent expansion of the superfluid 3He-B phase in the metastable, hypercooled A phase. An overview of the theory of dynamical phenomena in Fermi superfluids is presented in Chapter 1 with an eye towards formulating a theory …

Studies towards the synthesis of the core of Sarains A, B, & C
Sarains A-C are alkaloids isolated from the Mediterranean sponge Reniera sarai, which possess moderate antibacterial, insecticidal and antitumour properties. These alkaloids are popular targets for total synthesis, thanks to their rather unusual and challenging structure, which consists of a …

Synthesis and cytotoxity of oxysterols:studies on the A,B ring polyoxygenated sterols
Oxysterols (OS), the polyoxygenated sterols, represent a class of potent regulatory molecules for important biological actions. Cytotoxicity of OS is one of the most important aspects in studies of OS bioactivities. However, studies, the structure-activity relationship (SAR) study in particular, …

B phase nucleation and A-B interface dynamics in superfluid helium-3
This thesis deals with the theory of the primary nucleation and subsequent expansion of the superfluid $\sp3$He-B phase in the metastable, hypercooled A phase. An overview of the theory of dynamical phenomena in Fermi superfluids is presented in Chapter 1 with an eye towards formulating a theory …

The metaphysics of time investigations in tense-logic and a B-series semantics
The view that time flows from the future to the present and then recedes into the past is both natural and deeply problematic. So called 'A-theories' about time claim that this is the fundamental nature of temporality. This is not the view which will be defended in this paper. Rather I shall argue …
