Electron stimulated electron emission from solid surfaces
Thesis
Wright, B. (1974). Electron stimulated electron emission from solid surfaces

The topic of electron stimulated secondary electron emission is introduced in relation to studies in surface physics. In addition, some of the more recent literature in this subject is reviewed and critically appraised.
An apparatus for high resolut... Read More about Electron stimulated electron emission from solid surfaces.

A chemical investigation into the moulting hormones of the barnacle Balanus balanoides
Thesis
Morton Bebbington, P. (1975). A chemical investigation into the moulting hormones of the barnacle Balanus balanoides

In an attempt to detect and identify the moult-inducing substances in the barnacle, Balanus balanoides, one and a half metric tonnes of barnacle material was collected and extracted. Two known arthropod moulting hormones were detected in significant... Read More about A chemical investigation into the moulting hormones of the barnacle Balanus balanoides.

X-ray studies of monochloroacetamide and benzanilide
Thesis
Collis, P. G. (1975). X-ray studies of monochloroacetamide and benzanilide

The crystal structures of monochloroacetamide and benzanilide have been determined by X-ray diffraction methods.
Monochloroacetamide was found to crystallise in the space group P2,1/c, with four molecules in the monoclinic unit cell of dimensions
a... Read More about X-ray studies of monochloroacetamide and benzanilide.

Synthetic routes to 9-azasteroids
Thesis
Easom, J. M. (1975). Synthetic routes to 9-azasteroids

Syntheses of azasteroids both from natural steroids and from precursors bearing a nitrogen atom are reviewed.
The present research was directed towards the preparation of suitable tricyclic compounds possessing the future A-,B- and D-rings of a 9-az... Read More about Synthetic routes to 9-azasteroids.

Construction and investigation of an atomic hydrogen beam maser
Thesis
Lightfoot, H. W. (1975). Construction and investigation of an atomic hydrogen beam maser

Details are given of the design and construction of an atomic hydrogen beam maser. The static and dynamic properties of the maser are investigated and discussed. In particular, various .methods of oscillation amplitude transient production are studie... Read More about Construction and investigation of an atomic hydrogen beam maser.

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... Read More about Design, construction and investigation of an ammonia beam maser operated under conditions of strong oscillation.

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;...
