Micro-chemical investigations of volatile chemicals of some myrmicine ants
Thesis
(1983). Micro-chemical investigations of volatile chemicals of some myrmicine ants

The volatile chemicals originating from the poison glands, Dufour glands, mandibular glands and postpharyngeal glands of several species of myrmicine ants have been investigated. A number of novel micro-methods were developed and several advances mad... Read More about Micro-chemical investigations of volatile chemicals of some myrmicine ants.

Theoretical and synthetic approaches to the photochemistry of annulated tropones
Thesis
(1983). Theoretical and synthetic approaches to the photochemistry of annulated tropones

The syntheses of 5H-cyclohepta[b]pyrIdin-5-one, 9H-cyclo- hepta[b]pyridine-9-one, 5H-cyclohepta[c]pyridin-5-one and 9H-cyclo hepta[c]pyridin-9-one are reported.
The photolysis of these compounds and 4H-cyclohepta[b]furan -4-one are reported together... Read More about Theoretical and synthetic approaches to the photochemistry of annulated tropones.

The preparation and complexing properties of isocyanide-functionalized polymers
Thesis
Csorba, J. (1988). The preparation and complexing properties of isocyanide-functionalized polymers

This thesis is concerned with the synthesis of an isocyanide- functionalized polymer support and an investigation of the metal complexing properties of the resin produced.
The synthesis of two functionalized monomers, p-vinylbenzylformamide and m/p-... Read More about The preparation and complexing properties of isocyanide-functionalized polymers.

An A.E.S. study of S.E.E. and electron beam effects at oxygen exposed aluminium surfaces
Thesis
Adem, E. H. (1985). An A.E.S. study of S.E.E. and electron beam effects at oxygen exposed aluminium surfaces

An AES technique has been used to Investigate oxygen adsorption at clean polycrystalline aluminium surfaces. The adsorption process was found to consist of two stages: chemisorption, reached within the first 50L of oxygen exposure, is followed by an...

Adaptive techniques for signal enhancement in the human electroencephalogram
Thesis
Winski, R. (1985). Adaptive techniques for signal enhancement in the human electroencephalogram

This thesis describes an investigation of adaptive noise cancelling applied to human brain evoked potentials (EPs), with particular emphasis on visually evoked responses. The chief morphological features and signal properties of EPs are described. Co... Read More about Adaptive techniques for signal enhancement in the human electroencephalogram.

The reactions of trivalent phosphorus compounds with electrophilic acetylenes
Thesis
Caesar, J. C. (1986). The reactions of trivalent phosphorus compounds with electrophilic acetylenes

This thesis is concerned with the investigation of the reactions of some trivalent phosphorus compounds with electrophilic acetylenes, and in particular dimethyl acetylenedicarboxylate.
These studies have involved extensive use of nuclear magnetic r... Read More about The reactions of trivalent phosphorus compounds with electrophilic acetylenes.

Electron paramagnetic resonance studies of spin-labelled ethidium bromide DNA interactions
Thesis
Keeble, D. J. (1986). Electron paramagnetic resonance studies of spin-labelled ethidium bromide DNA interactions

Spin-Labelled Ethidium Bromide (SLEB) was prepared in order to study its interactions with natural DNA in the form of fibres . The technique of electron paramagnetic resonance was used in this thesis. Knowledge of the conformational transition pathwa...

The determination of excess thermodynamic functions of binary liquid mixtures
Thesis
Sibanda, V. S. (1986). The determination of excess thermodynamic functions of binary liquid mixtures

The work involved the determination of excess thermodynamic functions of binary liquid mixtures by experimental and theoretical means. Experimentally, excess Gibbs functions(GE), and excess volumes(VE) were determined. The theoretical work involved t...

Optoacoustic frequency stabilization of a carbon dioxide laser
Thesis
Abdallah Abu-Taha, M. I. (1987). Optoacoustic frequency stabilization of a carbon dioxide laser

In this thesis a study has been made of the design, construction and, in particular, frequency stabilization of a d.c. excited carbon dioxide laser. The outline of the theory of the carbon dioxide laser is presented as a prelude to a detailed study o... Read More about Optoacoustic frequency stabilization of a carbon dioxide laser.

Kinetic studies of polyene exchange and substitution in low valent octahedral metal complexes
Thesis
Ashford, N. F. (1987). Kinetic studies of polyene exchange and substitution in low valent octahedral metal complexes

The kinetics of polyene exchange and substitution in (polyene)Cr(CO)3 complexes has been investigated. The exchange reaction involving displacement of complexed polyene for free polyene (Chapter 2) has shown two competing rate determining pathways to...
