This paper presents an efficient lossless compression method to reduce the storage requirement and transmission time for radiographic non‐destructive testing images of aircraft components. The method is based on a combination of predictive coding and the integer wavelet transform. By using the component CAD model to divide the radiographic image of aircraft components into different regions with each region having the same material structure, the parameters of the predictors and the choice of the integer wavelet transform are optimised according to the specific image features contained in each region. Using a real radiographic image of a practical aircraft component as an example, the proposed method is presented and shown to offer a significantly higher compression ratio than other lossless compression schemes currently available.

The purpose of this paper is to investigate the effect of expandable graphite (EG) plates’ incorporation on the mechanical, thermal and fire-retardant properties of an epoxy–aliphatic amine system. In addition, the optimum amount of EG in epoxy/EG composites is determined to achieve the best thermal and mechanical properties at the same time.

The epoxy/EG composites were prepared by using (1-4) phr of EG. The morphological structure of epoxy/EG composites was studied by using scanning electron microscopy. The thermal, flame-retardant and mechanical properties of epoxy/EG composites were evaluated by using thermogravimetric analysis (TGA), oxygen index test and dynamic mechanical analysis and tensile and impact test, respectively.

TGA results showed that the incorporation of EG to the epoxy resin increased the initial decomposition temperature and residue weight of the composites. It was found that, with increasing EG concentration up to 4 phr, the oxygen index, glass transition temperature and Young’s modulus of epoxy/EG composites increased up to 60 per cent, 4.1°C and 50 per cent, respectively. On the other hand, the sample with 2 phr EG provided the maximum values of tensile strength, storage modulus, cross-linking density, ultimate tensile strain and impact strength.

Prepared epoxy/EG composites can be used as halogen-free flame-retardant composites. The proposed process for the preparation of the composites is simple and can easily be implicated in the industry.

To the best of the authors’ knowledge, there is no other publication that considers mechanical, thermal and fire-retardant properties of epoxy/EG composites in one paper. In this work, the optimum concentration of EG in epoxy/EG composites was determined, considering all these properties.

BY the time these words appear the majority of those who attend Library Association Conferences will have made tentative arrangements for their visit to Margate in June. Already, we understand, adhesions are coming in as many in number as for any September conference, and, if this is so, the fact will reassure those who have doubts of the wisdom of the change from September to June. We give on other pages some outline of the programme and in Letters on Our Affairs are presented with a Study of the subjects of the papers. Here we can concentrate upon one or two important points.

GUEST editor of this South African issue of THE LIBRARY WORLD is Hendrik M. Robinson, Director of Library Services, Transvaal Provincial Administration, Pretoria.

The British Gliding Association lias rightly called attention to the need for an artificial horizon suitable for use in a sailplane. This note argues that the artificial horizon, together with the directional gyro, form the ideal pair of instruments for the accurate and safe Hying of sailplanes in clouds. A description is given of a pair developed from German instruments together with full details of their weight, size and current consumption. It is shown that for a total weight of 20 lb. a sailplane can he fitted with an electrically driven horizon and directional gyro which will run continuously for over six hours before the batteries need recharging.

SAYS the handout from the Department of Industry: “The key role played by managers in improving British industry's economic performance was emphasised by Mr. Eric Varley, Secretary of State for Industry. He said that the publication of a discussion paper on industry, education and management underlined that industry in Britain today had many first class managers who made vital contributions to the economy.

The purpose of this paper is to identify if and how the see-now-buy-now model impacts the traditional buying, merchandising and supply chain processes (BMSCP) of multi-brand fashion retailers (MBFR) and whether they need to be adapted in order to facilitate this development.

This exploratory study includes three industry case studies, triangulated with external observers. A total of 11 semi-structured interviews were conducted within Germany and the UK.

Findings demonstrate that in order to adopt the see-now-buy-now model there is a need for process-shortening, as well as better process and network alignment between MBFR and brands through agility, supplier–relationship management and vertical integration in order to stay competitive against time-based competition. Whilst most steps of the traditional BMSCP are still applicable under the see-now-buy-now model, they must be re-engineered and shortened, with the steps being rolling rather than linear, with buyers and merchandisers operating in a more hybrid role.

This paper addresses the lack of research on the see-now-buy-now model as well as on the BMSCP of MBFR and the implications that see-now-buy-now could have on those processes. A modified buying, merchandising and supply chain framework adapted to incorporate see-now-buy-now is created which will be useful for academics and practitioners.

It was stated by a philosopher of very early days that the Gods sell their choicest goods in the cheapest market; and, it may be added, if it is necessary to impress such an obvious truism, that the greatest poverty may often be found in the midst of riches. The herring well illustrates the truths of the above paragraph.

The purpose of this article is to review the potential contributions of category management (CM) to the UK fashion sector and subsequently to establish evaluation criteria for the application of CM in the UK fashion sector.

Qualitative research was employed through an exploratory case study method.

Category management is limited in its application in the fashion industry. The study found that fashion companies adopted collaborative structures in order to implement a CM approach and a CM approach contributes to the development of a fast fashion business orientation.

Exploratory case study method does not allow for the results to be generalised.

The paper proposes a model of the evaluation of the application of category management in the fashion sector.

Smedleys Ltd v. Breed effectively disposes of Section 3 (3), Food and Drugs Act, 1955 as a defence in law in what nowadays constitutes the commonest source of all food prosecutions, viz., foreign matter in food. Their Lord‐ships' judgment is indeed a brilliant exposition of the law on the subject, but the result of their dismissal of the appeal can only be seen, as one of their number stated, that local authorities and magistrates for all practical purposes can ignore the subsection, and from the numerous reports of legal proceedings, this is what they have been doing for many years. It was resurrected in a case, similar in circumstance to that in Smedleys, a couple of years ago, in respect of a snail in black currant jam, in which the snail and black currants were identical in size and appearance.
