The composition of the europium–thenoyltrifluoroacetone (TTA)–trioctylphosphine (TOPO) chelate in water in the presence of Triton X-100 was investigated. The stoichiometric composition was found to be Eu(TTA) 3 (TOPO) 2 , but different compositions can occur depending on the relative concentrations of the ligands. The…

Abstract— The dynamic strain ageing (DSA) behaviour of A533B Class 1 reactor pressure vessel (RPV) steel, containing 5 ppm of free nitrogen, has been investigated over a wide range of strain rates from 3 × 10 −7 to 3−10 −3 s −1 and temperatures from 20 to 350°C. The DSA was observed within certain temperature ranges a…

This paper considers the compression properties of yarns. A model is proposed which predicts the behaviour of yarns in compression; the model takes account of the structural characteristics of yarns and the finite dimensions of fibres. A device is described which has been successfully used to measure the effects of co…

Phenomenological modeling of the long term general corrosion of mild and low alloy steel specimens under marine conditions is considered, using weight loss as a function of time. A conceptual model for immersion corrosion, tidal corrosion and atmospheric corrosion under marine conditions is proposed. The model uses ac…

This paper considers the distribution of fibres in yarns and discusses the development of a model for the simulation of fibre distributions; the concept of ‘virtual location’ within the cross-section domain, which may contain a fibre, is introduced. The distribution of fibres in real yarns is compared with computer-ge…

A study has been undertaken of the structure-activity relationship of eight new chiral compounds having either a pyrazole (series P) or an isoxazole (series I) ring as a central bridge in the mesogenic core. The presence of dimers in the pyrazole compounds accounts for their lower P s values in comparison with the iso…
