The purpose of this paper is to evaluate the model of a rear pressure bulkhead with different design optimizations to meet the pressurized cabin requirements of an aircraft.

This paper presents the results of the static analysis of a dome-shaped rear pressure bulkhead model designed in Catia-v5. Numerical analysis of model meshed in hyper-mesh and solved using Opti-Struct for iterative design optimizations.

All the iterative models are analyzed at 9 Psi. Rear pressure bulkhead designed with L-section stringer shows better results than the model optimized with T-section stringer for the same thickness. The model optimized with L-shaped stinger also reduces the weight of the bulkhead without affecting the structural integrity.

It has been concluded in this paper that the selection of specific shapes of the stringers shows a significant influence on weight reduction.

This paper provides a topical, technical insight into the design and development of a rear pressure bulkhead. It also outlines the future development of dome-shaped rear pressure bulkhead.

This paper explores the historical roots of accounting for biodiversity and extinction accounting by analysing the 18th-century Naturalist's Journals of Gilbert White and interpreting them as biodiversity accounts produced by an interested party. The authors aim to contribute to the accounting history literature by extending the form of accounting studied to include nature diaries as well as by exploring historical ecological accounts, as well as contributing to the burgeoning literature on accounting for biodiversity and extinction accounting.

The authors’ method involves analysing the content of Gilbert White's Naturalist's Journals by producing an 18th-century biodiversity account of species of flora and fauna and then interpretively drawing out themes from the Journals. The authors then provide a Whitean extinction account by comparing current species' status with White's biodiversity account from 250 years ago.

This paper uses Gilbert White's Naturalist's Journals as a basis for comparing biodiversity and natural capital 250 years ago with current species' status according to extinction threat and conservation status. Further the paper shows how early nature diary recording represents early (and probably the only) forms of accounting for biodiversity and extinction. The authors also highlight themes within White's accounts including social emancipation, problematisation, aesthetic elements and an example of an early audit of biodiversity accounting.

There are limitations to analysing Gilbert White's Naturalist's Journals given that the only available source is an edited version. The authors therefore interpret their data as accounts which are indicative of biodiversity and species abundance rather than an exactly accurate account.

From the authors’ analysis and reflections, the authors suggest that contemporary biodiversity accounting needs to incorporate a combination of narrative, data accounting and pictorial/aesthetic representation if it is to provide a rich and accurate report of biodiversity and nature. The authors also suggest that extinction accounting should draw on historical data in order to demonstrate change in natural capital over time.

Social implications include the understanding gleaned from the authors’ analysis of the role of Gilbert White as a nature diarist in society and the contribution made over time by his Journals and other writings to the development of nature accounting and recording, as well as to one’s understanding and knowledge of species of flora and fauna.

To the authors’ knowledge this is the first attempt to analyse and interpret nature diaries as accounts of biodiversity and extinction.

I SUPPOSE that anyone writing anything on Gilbert and Sullivan ought to begin by stating where he stands in regard to the works of this extraordinary pair. For ‘G. & S.’ is curious. It can perhaps be likened to cricket in that people tend either passionately to love it or as passionately to loathe it; neutrality is encountered relatively seldom. So let me say straight away that I come into the former category. H.M.S. Pinafore and all the other operas in the series have given me enormous pleasure for as long as I can remember, and I hope and believe they will continue to do so in the future.

ALUMINIUM CENTENARY. A HUNDRED years ago, at the Paris Exposition of 1855, Prof. Ste. Claire Deville exhibited samples of aluminium which he had extracted from clay by a chemical process. It was not until a generation later, in 1886, that the electrolytic process for extracting aluminium from its oxide was patented simultaneously by Charles Martin Hall in America and Paul Hérault in France. Today, using basically that same method of extraction, 30,000 tons a year of pure aluminium are produced in Britain alone at the hydroelectric plant in the Scottish highlands, and world production in 1954 has probably exceeded 3 million tons a year.

The foundation collection of the printed books now forming the Library of the British Museum was that of Sir Hans Sloane. This comprised about 40,000 volumes. To it was added in 1759 the Royal collection, begun in the time of Henry VII and inherited by George II from his predecessors on the throne.

In the last four years, since Volume I of this Bibliography first appeared, there has been an explosion of literature in all the main functional areas of business. This wealth of material poses problems for the researcher in management studies — and, of course, for the librarian: uncovering what has been written in any one area is not an easy task. This volume aims to help the librarian and the researcher overcome some of the immediate problems of identification of material. It is an annotated bibliography of management, drawing on the wide variety of literature produced by MCB University Press. Over the last four years, MCB University Press has produced an extensive range of books and serial publications covering most of the established and many of the developing areas of management. This volume, in conjunction with Volume I, provides a guide to all the material published so far.
