scholarly journals Studies upon catalytic combustion.— Part I. The union of carbon monoxide and oxygen in contact with a gold surface

The experiments which will be described in this and succeeding papers of the series are a continuation of the previous researches of Bone and Wheeler upon “The Combination of Hydrogen and Oxygen in Contact with Hot Surfaces,” which were published in 1906. They were begun at Manchester University twenty years ago, continued at the University of Leeds, and are now being completed at the Imperial College of Science and Technology, London. The delay in publishing the results has not been disadvantageous, because it has allowed of our testing some recent theoretical developments concerning catalytic combustion, and more particularly that due to Langmuir. These, it will be remembered, formed the subject of a special discussion held in London on September 20, 1921, under the auspices of the Faraday Society, in which a number of the leading investigators throughout the world participated. The previous work of Bone and Wheeler ( loc . cit .), in which the actions of a number of widely different hot surfaces upon the combination of hydrogen and oxygen at pressures between 500 and 50 mm. were systematically studied, had disclosed the following outstanding facts:— (1) That the catalyzing power of a new surface at a given temperature usually increases up to a certain steady “normal” state, after which the rate of steam formation is always directly proportional to the pressure, provided that the two gases (hydrogen and oxygen) are present in their combining ratios, and that the product (steam) is rapidly removed from the sphere of action.

In connection with the researches upon catalytic combustion conducted in my laboratories for some years past, a great deal of attention has been paid to the experimental investigation of the important question of whether or no the presence of moisture has any specific influence upon the catalytic combustion of carbonic oxide. The present paper embodies the principal results of our investigations up to date. They were begun in 1908 at the University of Leeds, in collaboration with the two Gas Research Fellows—Mr. A. Forshaw, M. Sc., and Dr. H. Hartley—as well as with Mr. A. Appleyard, B. Sc., and have been completed at the Imperial College of Science and Technology, London, with the collaboration of the late W. A. Haward, M. Sc., Mr. S. Robson, B. Sc., A. Whitaker, B. Sc., and Prof. D. S. Chamberlin, of Lehigh University, U. S. A., who recently spent a "sabbatical year" working with us. The difficult nature of the experimental work involved operations demanding the utmost care, great attention to details, and unusual skill on the part of my collaborators. The surfaces experimented with were porous porcelain, the oxides of copper and nickel, gold and silver, And, in view of the importance of the results in connection with the theoretical aspects of the subject, many independent repetitions of the experiments were made at various times to ensure their complete confirmation. In the case of a very porous surface, such as fireclay or porous porcelain, it was ultimately found necessary to extend a given experiment uninterruptedly day and night over three months, in order to ensure complete dryness of the system. Indeed, not until the later stages of the research was it possible to view correctly and reconcile all the results.


It is my pleasant duty to welcome you all most warmly to this meeting, which is one of the many events stimulated by the advisory committee of the William and Mary Trust on Science and Technology and Medicine, under the Chairmanship of Sir Arnold Burgen, the immediate past Foreign Secretary of the Royal Society. This is a joint meeting of the Royal Society and the British Academy, whose President, Sir Randolph Quirk, will be Chairman this afternoon, and it covers Science and Civilization under William and Mary, presumably with the intention that the Society would cover Science if the Academy would cover Civilization. The meeting has been organized by Professor Rupert Hall, a Fellow of the Academy and also well known to the Society, who is now Emeritus Professor of the History of Science and Technology at Imperial College in the University of London; and Mr Norman Robinson, who retired in 1988 as Librarian to the Royal Society after 40 years service to the Society.

The purpose of this article is to stimulate debate about the developing paradoxes and dilemmas facing the university academic. This article argues that academics are increasingly being steeped in an inauthentic existence due, at least partly to, egocentrism and sociocentrism. A modest transdisciplinary- existential analytical framework is applied as an intellectual method to reflect on the prevailing monological perspectives stifling the role of academics, in working towards building a more sustainable future. Using concepts such as the subject, facticity and transcendence, the article investigates the dialectical tensions between some of these monological perspectives and proposes avenues to create new possibilities to progress the role of the academic. The article argues that the multilogical perspectives of transdisciplinary thinking and the empowering perspectives of existential thinking can provide academics with the necessary conceptual tools to transcend egocentrism and sociocentrism. While it is likely that new contradictions will emerge as a result of this synthesis, open-minded academics are urged to ignite their imaginative powers and take up the challenge of creating and acting on new possibilities. A transdisciplinary-existential dialectical approach can provide a richer understanding of present dilemmas in academia and the world, and suggest more satisfying paths to a sustainable future.

In its third edition, the “William Morris Davis – Journal of Geomorphology” presents its second interview with geographers, to head the “Interviews” section, which opens each published issue. This time, it is the first international interview, carried out with Professor Philip van Beynen, from the University of South Florida, in the United States. Professor Philip van Beynen was interviewed on the topic “Karst in Urban Areas”, and brings important data on the subject, with beautiful illustrations and with examples from all over the world. The interview took place on September 17, 2020, with the participation of Vanda de Claudino-Sales (Professor of the Academic Master in Geography at the State University of Vale do Acarau-UVA) and Saulo Roberto Oliveira Vital (Professor of the Department of Geography and the Post-Graduate Program in Geography at the Federal University of Paraiba - UFPB), and was transcribed by Diego Nunes Valadares, master's student on Geography at the Federal University of Rio Grande do Norte. Professor van Beynen was born in New Zealand, where he received his degree in Geography at the University of Auckland. He earned a master's degree from the same university, and a doctorate and post-doctorate from McMaster University, Canada. He has been a professor at the School of Geoscience at the University of South Florida since 2009, where he   has been developing research related to different components of karst environments. The interview shows his great expertise on the subject, and is very much worth to be read and seen even for those who are not specialists in karst.

Sustainability and its relationship with education has been the subject of much contestation in recent decades. This article reviews some of the debates on sustainability in the context of higher education and raises concern about the narrowing of the discourse on sustainability and sustainability education in the neoliberal university. The methods used in this article are philosophical, combining traditional concept analysis with concept creation. The later method holds that philosophical concepts are created or reimagined so that they have transformative effects in the world. The key finding of this conceptual exploration is that sustainability (education) can be liberated from the fetters of neoliberalism and can be imagined differently. This might be possible in the “University of Beauty”. Moreover, the potential for reimagining sustainability higher education already exists within the neoliberal university and in those who inhabit it. This is because sustainability higher education and those who inhabit the neoliberal university are always in the process of becoming. The article concludes that the present generation of students should be viewed as key role players in rethinking sustainability higher education.

Considering that, except for the initial period of the Emergency, Malaysia as a country attracted far less attention internationally than most of the other countries in Southeast Asia, it is somewhat surprising to find that many foreign historians did not hesitate to make Malaysian history the subject of their scholarly works. L.A. Mills wrote in 1924, 1942, and again in 1958; Rupert Emerson in 1937. In 1935, a Ph.D. thesis was completed by M.I. Knowles in the University of Wisconsin. In 1943, Virginia Thomson wrote Postmortem on Malaya. The post-1950 situation was even more exciting. Numerous theses on Malaysia were written in various universities in the world — among them SOAS, ANU, Hong Kong, California, Columbia, and Duke. Of course, by far the greatest volume of work was done in the University of Malaya (Singapore) itself where, between 1951 and 1961, more than a hundred theses were completed at both the graduate and undergraduate levels. Understandably, in the mid-sixties, there was a growing feeling that the field was being exhausted.

Salimbene called the Franciscan Adam Marsh ‘one of the greatest clerks of the world’, an accolade he reserved for a small group of men whom he regarded as the master minds of his time. A glance at Adam's letters suggests that Salimbene's opinion was widely shared by Adam's contemporaries. Few men without official position can have had their advice so eagerly sought by so many different people in high places. He was the counsellor of Henry III and the queen, the confidant of Simon de Montfort and his wife, the mentor of bishops and consultant to the rulers of his order. He enjoyed the trust of men as different as Archbishop Boniface of Savoy, who tried to recruit him to his familia, and Grosseteste, a lifelong friend, with whom he collaborated in the study and transmission of Greek texts. He moved with equal assurance in the world of ecclesiastical politics and the scholastic world of the university. The nature of his political influence has been the subject of frequent surmise, but the importance of his part in directing the Franciscan school at Oxford and creating the scholastic organisation of the English province has long been recognised. Yet several phases of his career and life remain obscure or at best enigmatic. My object here is to elucidate some of the more opaque points of his career and to re-examine his place in the history of the early Franciscan school.
