Abstract

Purpose

Low friction polymer coatings able to withstand high loadings and many years of continuous operation are difficult to formulate at low cost, but could find many applications in industry. This study aims to analyze and compare friction and wear performance of novel polydopamine/polytetrafluoroethylene (PDA/PTFE) and traditional tin Babbitt coatings applied to an industrial journal bearing.

Design/methodology/approach

This paper tested PTFE based coating, co-deposited with PDA, a biopolymer allowing sea mussels to adhere to ocean rocks. This coating was deposited on flat steel substrates and on a curved cast iron hydrodynamic journal bearing surface. The flat substrates were analyzed with a tribometer and an optical microscope, while the coated bearing liners were tested in an industrial laboratory setting at different speeds and different radial loads.

Findings

PDA/PTFE coating showed 2-3 times lower friction compared to traditional tin Babbitt for flat substrates, but higher friction in the bearing liners. PDA/PTFE also showed considerable wear through coating delamination and abrasion in the bearing liners.

Research limitations/implications

Five future modifications to mitigate coating flaws are provided, which include modifications to coating thickness and its surface finish.

Originality/value

While the novel coating showed excellent results on flat substrates, coating performance in a large scale bearing was found to be poor. This study shows that coating preparation needs to be improved to avoid frictional losses and unwanted damage to bearings. We provide several routes that could improve coating performance in industrial applications.

Abstract

THE enterprise of two London newspapers, the Tribune (for the second time) and the Daily Chronicle, in organizing exhibitions of books affords a convenient excuse for once again bringing forward proposals for a more permanent exhibition. On many occasions during the past twenty years the writer has made suggestions for the establishment of a central book bazaar, to which every kind of book‐buyer could resort in order to see and handle the latest literature on every subject. An experiment on wrong lines was made by the Library Bureau about fifteen years ago, but here, as in the exhibitions above mentioned, the arrangement was radically bad. Visiting the Daily Chronicle show in company with other librarians, and taking careful note of the planning, one was struck by the inutility of having the books arranged by publishers and not by subjects. Not one visitor in a hundred cares twopence whether books on electricity, biography, history, travel, or even fairy tales, are issued by Longmans, Heinemann, Macmillan, Dent or any other firm. What everyone wants to see is all the recent and latest books on definite subjects collected together in one place. The arrangements at the Chronicle and Tribune shows are just a jumble of old and new books placed in show‐cases by publishers' names, similar to the abortive exhibition held years ago in Bloomsbury Street. What the book‐buyer wants is not a miscellaneous assemblage of books of all periods, from 1877 to date, arranged in an artistic show‐case and placed in charge of a polite youth who only knows his own books—and not too much about them—but a properly classified and arranged collection of the newest books only, which could be expounded by a few experts versed in literature and bibliography. What is the use of salesmen in an exhibition where books are not sold outright? If these exhibitions were strictly limited to the newest books only, there would be much less need for salesmen to be retained as amateur detectives. Another decided blemish on such an exhibition is the absence of a general catalogue. Imagine any exhibition on business lines in which visitors are expected to cart away a load of catalogues issued separately by the various exhibitors and all on entirely different plans of arrangement! The British publisher in nearly everything he does is one of the most hopeless Conservatives in existence. He will not try anything which has not been done by his grandfather or someone even more remote, so that publishing methods remain crystallized almost on eighteenth century lines. The proposal about to be made is perhaps far too revolutionary for the careful consideration of present‐day publishers, but it is made in the sincere hope that it may one day be realized. It has been made before without any definite details, but its general lines have been discussed among librarians for years past.

Abstract

Purpose

In 1867, the author Samuel Langhorne Clemens, better known as Mark Twain, undertook a great pleasure excursion across Europe. Visiting a range of sites, from those associated with the Christian Cult of Death to the notable cultural heritage attractions of the time, Twain published his experiences in what would later become one of the world's best‐selling travelogues; The Innocents Abroad, or the New Pilgrim's Progress. This essay offers a rereading of Twain's encounters, proposing examination of Twain's encounters as timely and useful in addressing what Seaton identifies as a gap in data on thanatourism consumption.

Design/methodology/approach

The essay draws on contemporary thanatourism theoretical frameworks, including Seaton's “Continuum of intensity” and “Thanatourism developmental sketch”; Sharpley's “Matrix of dark tourism supply and demand” and Stone and Sharpley's “Dark tourism consumption framework”, among others, to explore Twain's encounters.

Findings

Supplemented by a review of recent theoretical thanatourism research, the essay proposes three findings. Finding one illustrates that Twain's encounters, although not always pre‐motivated or purposefully supplied, were emotionally charged and deeply affective experiences, which had the potential to provoke ontological insecurity. Finding two highlights the potential of the geography of death to stimulate emotional reactions and configure individual and societal interactions with death. Finding three argues a need for new methodological approaches to understanding the thanatourism experience; approaches that are empathetically sensitive to the potentially powerful impact of the thanatourism experience.

Originality/value

The essay draws on a classic travelogue to help address the imbalance in knowledge of the thanatourism experience. The essay argues that thanatourism is a layered and complex phenomenon, highly personal and often a potentially powerful and emotionally affective experience.

Abstract

The Student Christian Movement (SCM) arose from the formal integration in one unit of a number of different strands of student‐run evangelical religion in British Universities(1). The Jesus Lane Sunday School in Cambridge, staffed by students, had been open since 1827. David Livingstone's visit to Cambridge in 1858 inspired the Church Missionary Union and in the same period Cambridge students began a Daily Prayer Meeting. In 1877, the students brought their various efforts together into the Cambridge Inter‐Collegiate Christian Union (CICCU). Similar movements were developing in other colleges. The first major links were created by the “Cambridge Seven”. Even at the end of the period of the “Saints” (as Wilberforce and his fellow evangelicals were known), more than three‐quarters of the men who volunteered for foreign missions were artisans, shop‐boys, labourers and apprentices(2).

Abstract

THE catalogue, as a library appliance of importance, has had more attention devoted to it than, perhaps, any other method or factor of librarianship. Its construction, materials, rules for compilation and other aspects have all been considered at great length, and in every conceivable manner, so that little remains for exposition save some points in the policy of the catalogue, and its effects on progress and methods. In the early days of the municipal library movement, when methods were somewhat crude, and hedged round with restrictions of many kinds, the catalogue, even in the primitive form it then assumed, was the only key to the book‐wealth of a library, and as such its value was duly recognized. As time went on, and the vogue of the printed catalogue was consolidated, its importance as an appliance became more and more established, and when the first Newcastle catalogue appeared and received such an unusual amount of journalistic notice, the idea of the printed catalogue as the indispensable library tool was enormously enhanced from that time till quite recently. One undoubted result of this devotion to the catalogue has been to stereotype methods to a great extent, leading in the end to stagnation, and there are places even now where every department of the library is made to revolve round the catalogue. Whether it is altogether wise to subordinate everything in library work to the cult of the catalogue has been questioned by several librarians during the past few years, and it is because there is so much to be said against this policy that the following reflections are submitted.

Abstract

SOME amount of loss by enemy action has occurred in libraries since our last writing, but none of it has been on such a scale as we had to record earlier. This may be due to the more restricted raiding of the winter months, and, as we have so often remarked, is no assurance that more and great damage may not be endured—for it will be endured—when the boasted offensive takes place. It is gratifying to know that readers in heavily bombed areas continue faithful to libraries. Books have taken an even higher place lately, and if in these areas the circulation figures are smaller, it is because the populations are smaller. Individual readers use more books than ever.

Abstract

LIBRARIES have come impressively into the public picture in the past year or two, and seldom with more effect than when Their Majesties the King and Queen opened the new Central Reference Library at Manchester on July 17th. In a time, which is nearly the end of a great depression, that the city which probably felt the depression more than any in the Kingdom should have proceeded with the building of a vast store‐house of learning is a fact of great social significance and a happy augury for libraries as a whole. His Majesty the King has been most felicitous in providing what we may call “slogans” for libraries. It will be remembered that in connection with the opening of the National Central Library, he suggested that it was a “University which all may join and which none need ever leave” —words which should be written in imperishable letters upon that library and be printed upon its stationery for ever. As Mr. J. D. Stewart said at the annual meeting of the National Central Library, it was a slogan which every public library would like to appropriate. At Manchester, His Majesty gave us another. He said: “To our urban population open libraries are as essential to health of mind, as open spaces to health of body.” This will be at the disposal of all of us for use. It is a wonderful thing that Manchester in these times has been able to provide a building costing £450,000 embodying all that is modern and all that is attractive in the design of libraries. The architect, Mr. Vincent Harris, and the successive librarians, Mr. Jast and Mr. Nowell, are to be congratulated upon the crown of their work.
