Design, construction and investigation of an ammonia beam maser operated under conditions of strong oscillation
Thesis
Maroof, A. (1975). Design, construction and investigation of an ammonia beam maser operated under conditions of strong oscillation

In this thesis, the principle, construction and operation of an ammonia beam maser oscillator of advanced design are described. The maser discussed is characterized by the production of an intense molecular beam with a nozzle-skimmer gas source comb...

An investigation into the analysis of ecdysones and other steroid hormones
Thesis
Poole, C. F. (1975). An investigation into the analysis of ecdysones and other steroid hormones

As an aid to the analysis of ecdysones (arthropod moulting hormones), an investigation has been carried out to find an efficient and sensitive method for determining them by chromatography. A series of fluorocarbonsilanes were synthesized and tested... Read More about An investigation into the analysis of ecdysones and other steroid hormones.

The effects of mechanical tension and the steffimycin antibiotics on D.N.A. conformation
Thesis
Blakeley, P. J. (1976). The effects of mechanical tension and the steffimycin antibiotics on D.N.A. conformation

The conditions necessary to produce stable specimens of D.N.A. under mechanical tension were investigated. This involved the examination of the sodium chloride content of D.N.A. fibres and a study of the relative humidity range within which the stret...

Non-ideality in liquid mixtures: the prediction and measurement of thermodynamic excess functions
Thesis
Hewitt, F. A. (1976). Non-ideality in liquid mixtures: the prediction and measurement of thermodynamic excess functions

This thesis may be separated readily into three sectors: firstly, the mathematical prediction.of the excess functions of some well-known systems, and also of some new systems, the experimental data for which were gathered in the course of this work;...

Optical and x-ray diffraction studies of polynucleotides and their interaction with drugs
Thesis
Porumb, H. (1976). Optical and x-ray diffraction studies of polynucleotides and their interaction with drugs

The interactions in solution and the solid state oT the antibiotic drugs ethidium bromide, adriamvcin and daunomycin with deoxyribonucleic acid have been investigated with the aim of understanding at a molecular level the basis of their chemotherapeu...

An electron spin resonance study of drug binding to nucleic acids
Thesis
Porumb, T. (1976). An electron spin resonance study of drug binding to nucleic acids

The thesis presents a study of the interaction of paramagnetic derivatives of drugs with the nucleic acids, carried out using the electron spin resonance (ESR) technique. The general principles of ESR (particularly those concerned with the free radic... Read More about An electron spin resonance study of drug binding to nucleic acids.

Auger electron and characteristic energy loss spectroscopy of selected metals, semi-metals and compounds
Thesis
Singh, S. (1976). Auger electron and characteristic energy loss spectroscopy of selected metals, semi-metals and compounds

The topics of interest in surface science are introduced together with some of the experimental techniques used in their investigation. In particular the techniques of Auger Electron Spectroscopy (A.E.S.) and Characteristic Energy Loss Spectroscopy (...

Investigations of carbon fibres and their precursor materials by E.S.R. and related techniques
Thesis
Cooper, E. G. (1977). Investigations of carbon fibres and their precursor materials by E.S.R. and related techniques

The desirable mechanical properties that have lead to the manufacture of carbon fibre laminates for aerospace applications are developed in fibre heat treated in excess of 1000°C. The research group at Keele made an exhaustive study of these high tem... Read More about Investigations of carbon fibres and their precursor materials by E.S.R. and related techniques.

Studies on DNA polymorphism
Thesis
Goodwin, D. C. (1977). Studies on DNA polymorphism

Possible variations in the secondary structure and the A - B transition in DNA's of varying primary base sequence and composition have been studied by the techniques of X ray diffraction and molecular model building. The DNA's studied are from both b... Read More about Studies on DNA polymorphism.

Synthetic and mechanistic studies of some nitrene insertion reactions
Thesis
McKinley, W. H. (1977). Synthetic and mechanistic studies of some nitrene insertion reactions

A short review of aromatic nitrene chemistry is presented in the Introduction, with particular emphasis with recent developments reported in the literature. Part I of the discussion describes the thermolytic and photolytic decomposition of 2-azidotr... Read More about Synthetic and mechanistic studies of some nitrene insertion reactions.
