Spectroscopic studies of some haemoglobin derivatives
Thesis
Gray, K. (1974). Spectroscopic studies of some haemoglobin derivatives

This thesis describes a study of the magnetic and optical properties of human haemoglobin and certain of its derivatives. The techniques of electron spin resonance spectroscopy and optical spectrophotometry at low temperatures are used. An introduct...

Coupled molecule-radiation field effects in an ammonia beam maser
Thesis
Lefrere, P. R. (1974). Coupled molecule-radiation field effects in an ammonia beam maser

Details are given of a number of phenomena which have been observed in an advanced ammonia beam maser. These include cooperative effects arising during the build-up of oscillations, regenerative nutation, pulling and quenching of oscillations, induce...

Magnetic resonance studies of paramagnetic centres in oxide crystals
Thesis
McGeehin, P. (1974). Magnetic resonance studies of paramagnetic centres in oxide crystals

The results reported in this thesis were obtained using Electron Paramagnetic Resonance. Studies were made of previously neutron irradiated crystals of CaWO4 and CaO, and of the system CaO : Gd3+.

The thermochemistry of some transition metal complexes
Thesis
McNaughton, J. L. (1974). The thermochemistry of some transition metal complexes

In this thesis, thermochemical data for two different groups of transition-metal complex are reported. The first group of complexes is of the type MX2Ln, where M is a first-row transition-metal or Cd, X is a halogen and L is a heterocyclic ligand. T...

Fracture surface zones and crack-branching in some brittle plastics
Thesis
McQullin, B. R. (1974). Fracture surface zones and crack-branching in some brittle plastics

The phenomenon of crack-branching is examined. Other, pre-branching, fracture surface zones which arise on the tensile fracture surfaces of polymethylmethacrylate, polystyrene, and an epoxy resin are then described, and an attempt is made to account...

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...

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...

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.
