Abstract:

Chapter 1 is the introduction to the thesis. The general principles of radical cyclisation reactions are highlighted with a focus upon the reactivity of iminyl radicals. A more detailed discussion follows on radical cyclisations onto nitriles including examples of tandem cyclisations. The final section is concerned with cyano migration reactions, and provides evidence for the reversibility of these translocations. The investigation into tandem radical cyclisations of nitriles is discussed in Chapter 2. The aim of the project was to form bicyclic nitrogen heterocycles from acyclic precursors by

Abstract:

The study begins with an account of Blake, as voiced by Allen Ginsberg, taking part in a key Sixties anti-war protest, and goes on to examine some theoretical aspects of Blake's relationship with the Sixties. In Chapter One, I explore the relationship between ‘popular Blake', ‘academic Blake', and ‘countercultural Blake'. The chapter seeks to provide a revisionist account of the relationship between Blake's Sixties popularity and his earlier reception, suggesting that all three elements of Blake's Sixties reception – popular, academic and countercultural – have long been intertwined, and conti

Abstract:

The increased penetration of distributed generation (DG) mostly derived from renewable energy sources (RES) such as wind and photovoltaic (PV) systems presents two main forms of technical issues. The system is more susceptible to voltage-rise and equipment overload conditions, while the levels of uncertainty associated with the power system’s parameters increase significantly. The resulting networks characterised by the bi-directional flow of power, uncertainty from stochastic customer load variations and the intermittent generation from DGs, require appropriate load flow assessment tools.

Abstract:

Uncoupling proteins (UCPs) catalyse proton transport across the mitochondrial inner membrane, thereby uncoupling oxidative phosphorylation. UCP2 is expressed in several mammalian tissues including pancreatic β-cells. Since UCP2 activity uncouples the processes that link glucose metabolism (oxidation) to insulin secretion (phosphorylation), it is expected to attenuate glucose-stimulated insulin secretion (GSIS). Published studies using UCP2 over-expressing and UCP2 ablated β-cells support this hypothesis. Therefore, identifying regulators of β-cell UCP2 activity may help develop novel ways to t

We developed an approach to the β-thioenamide linkage contained in the S-(2-aminovinyl)cysteine (avCys) residue of thioviridamide.1,2 Kinetic and thermodynamic control of radical additions of thiols to ynamides were studied for the formation of β-thioenamide linkage. Thiyl radicals are electrophilic and ynamides are electron-rich alkynes. This complementary polarity of the radical and acceptor increases the likelihood of a successful radical addition reaction. Because little is known about these types of compounds (β-thioenamides), we were unsure what kinds of yields and stereoselectivities (c

Eight-day-old mung bean seedlings (Vigna radiata L.) grown in hydropondic medium were osmotically stressed by exposing roots to increasing concentrations of NaCl up to 4 bars. They were transferred after 16 to 18 hours to a similar solution containing tritiated water (THO). Periodic samples were taken of water transpiring from the leaves and of tissue water obtained from the same leaves, frozen and ground; specific radioactivity was determined by a scintillation counter. Proportional to increasing stress, the labelling of tissue water was increasingly delayed, the time for equilibration of the

A frequency analysis followed by a mode identification were done based on the high resolution spectroscopic data of one β Cephei star, PT Puppis, and two γ Doradus stars, HD 189631 and AC Lepus. Ex

Abstract:

This thesis argues that Stevie Smith's poetic style can be attributed to her gender. It shows that the dominant status of masculine poetry and poetics, and the prejudice against women poets, affected Smith's poetic style and led to her search for the source ofa feminine poetic voice. The prevailing circumstances when Smith began to publish poetry are examined in order to establish Smith's socially appropriate poetics. The thesis offers detailed textual analyses, informed by feminist theories. Chapters one and two take a socio-historic materialist approach to examine the problems confronting Sm

Abstract:

The photolysis of vicinal dibromoalkanes in acetonitrile produces bromine atoms and $\beta$-bromoalkyl radicals. Bromine atoms react with halide ions to produce easily detectable and long-lived radical anions $\rm (BrX\sp{\sbsp{\!-}{\bullet}}).$ The reaction of photolytically produced bromine atoms with iodide, bromide, chloride, and fluoride occurs with rate constants of (1.4 $\pm$ 0.8) $\times$ 10$\sp $ M$\sp{-1}$ s$\sp{-1}$, (1.6 $\pm$ 0.3) $\times$ 10$\sp $ M$\sp{-1}$ s$\sp{-1}$, (1.4 $\pm$ 0.1) $\times$ 10$\sp $ M$\sp{-1}$ s$\sp{-1},$ and (1.0 $\pm$ 0.1) $\times$ 10$\sp $ M$\sp{-1}$ s$\sp

Abstract:

This thesis represents the culmination of four years of research into two aspects of gas phase ion chemistry. The first was an attempt to obtain information on internal excitation in polyatomic projectile - target gas collisions in a mass spectrometer. Knowledge of internal excitation is critical to the interpretation of collision induced dissociation (CID) mass spectra. A novel collision cell was designed for a VG ZAB-2F sector mass spectrometer which permitted the detection and analysis of photon emissions from keV projectile - target gas collisions. Early experiments performed in the second

Abstract:

This thesis has analysed spectroscopic data for three stars in detail, the β Cephei star V2052 Ophiuchus, the γ Doradus star QW Puppis and the γ Doradus candidate star HD139095. Twelve other candidate γ Doradus stars have had their Vrotsin i, binary status and, where possible, the presence of line profile variation determined. A new technique utilising scaled delta functions has been developed to allow the extraction of a single, high S/N line profile from a high resolution and large wavelength range spectrum. This procedure has performed well in the γ Doradus stars examined. The application o

Abstract:

Dans cette thèse, nous utilisons différentes nanostructures plasmoniques pour contrôler l'émission de lumière excitée électriquement. Notre émission électrique provient d'une "nanosource STM" qui utilise le courant tunnel inélastique entre la pointe d'un microscope à effet tunnel (STM) et un échantillon métallique, pour exciter localement les plasmons polaritons de surface localisés et propagatifs. L’interaction de notre nanosource STM et d'une lentille plasmonique circulaire (une série de fentes concentriques gravées dans un film d'or épais) produit une microsource radialement polarisée de fa

Abstract:

Context: Approximately one billion people live in semi-arid and arid regions, and of these about 40% live on less than a dollar a day. Legumes crops are an important component of sustainable agriculture, but they are often grown under intermittent or terminal droughts. Thus, improving drought tolerance in legumes has the potential to improve food security and sustainability of agricultural systems. Objective: This study compares the response of two legume crops, common bean (Phaseolus vulgaris L.) and mungbean (Vigna radiata (L.) Wilczek), to water stress conditions under field and contro

Abstract:

The present work deals with the development and application of an acoustic long-period fiber grating (LPG) in conjunction with a special optical fiber (SF). The acoustic LPG converts selected optical modes of the SF. Some of these modes are characterized by complex, yet cylindrically symmetric polarization and intensity patterns. Therefore, they are the guided variant of so called cylindrical vector beams (CVBs). CVBs find applications in numerous fields of fundamental and applied optics. Here, an application to high-resolution light microscopy is demonstrated. The field distribution in the ti
