DEUTSCH Korrosion in Anlagen von Gaswerken, J. W. Chilver, B.Sc, A.R.I.C., M.bisl.Gas E. Obwohl sich durchgreifende Änderungen in der Gasindustrie vollziehen, wird noch für geraume Zeit ein wesentlicher Teil des Gases durch Kohlenentgasung und Karburieren von Wassergas erzeugt werden. Selbst diese herkommlicheren Methoden werden von Änderungen wie z. B. der Wahl minderwertigerer Kohlensorten zur Herstellung reaktiver, rauchloser Festbrennstoffe sowie der Verwendung leichter Kohlenwasserstoffole wie z. B. Primariibersud anstelle von Gasol nicht unberuhrt bleiben. Dieser Artikel behandelt einige der Korrosionsprobleme, wie sie bei Anlagen auftreten, die sich schon im grosseren Umfang durchgesetzt haben. Seite 11

Although the wind of change is blowing strongly through the gas industry a substantial proportion of the gas, for some time to come, will be made by coal carbonisation and by carburetting water gas. Even these more conventional methods will be subject to change such as the choice of lower‐rank coals to produce reactive smokeless solid fuels and the use of light Hydrocarbon oils, such as primary flash distillate, in place of gas oil. This article deals with some of the corrosion problems that arise in these more established types of plant.

The problems associated with preserving the steel sheeting of water‐sealed gasholders have been known for some time. Various techniques have been adopted, e.g. protective painting, oil filming and sacrificial anodes. This paper deals with painting, and the two groups of paints used in the experiments were chosen for (1) their blister‐suppressing qualities and (2) their good adhesion and water resistance.

There are very few individuals who have studied the question of weights and measures who do not most strongly favour the decimal system. The disadvantages of the weights and measures at present in use in the United Kingdom are indeed manifold. At the very commencement of life the schoolboy is expected to commit to memory the conglomerate mass of facts and figures which he usually refers to as “Tables,” and in this way the greater part of twelve months is absorbed. And when he has so learned them, what is the result? Immediately he leaves school he forgets the whole of them, unless he happens to enter a business‐house in which some of them are still in use; and it ought to be plain that the case would be very different were all our weights and measures divided or multiplied decimally. Instead of wasting twelve months, the pupil would almost be taught to understand the decimal system in two or three lessons, and so simple is the explanation that he would never be likely to forget it. There is perhaps no more interesting, ingenious and useful example of the decimal system than that in use in France. There the standard of length is the metre, the standard of capacity the cubic decimetre or the litre, while one cubic centimetre of distilled water weighs exactly one gramme, the standard of weight. Thus the measures of length, capacity and weight are most closely and usefully related. In the present English system there is absolutely no relationship between these weights and measures. Frequently a weight or measure bearing the same name has a different value for different bodies. Take, for instance, the stone; for dead meat its value is 8 pounds, for live meat 14 pounds; and other instances will occur to anyone who happens to remember his “Tables.” How much simpler for the business man to reckon in multiples of ten for everything than in the present confusing jumble. Mental arithmetic in matters of buying and selling would become much easier, undoubtedly more accurate, and the possibility of petty fraud be far more remote, because even the most dense could rapidly calculate by using the decimal system.

An increase in community engagement by governments across Australia’s three-tiered federal polity conforms to international trends. It represents a multidimensional institutionalization of participatory democracy designed to involve the public in decision-making. Increasingly, it is a practice which displays the markers of professionalization, including (self-described) professionals, professional associations and a code of ethics. The individuals who design, communicate, and facilitate community engagement are placed in a unique position, whereas most professions claim to serve both their client or employer and a greater public good, community engagement practitioners play these roles while also claiming to serve as “guardians” of democratic processes. Yet the claimed professionalization of community engagement is raising some questions: Is community engagement really a profession – and by what criteria ought this be assessed? What tensions do community engagement practitioners face by “serving multiple masters,” and how do they manage these? More pointedly, how can ethics inform our understanding of community engagement and its professionalization? This chapter examines the case for the practice of community engagement as a profession using Noordegraaf’s (2007) pillars of pure professionalism as a guide. It then explores some practical examples of the tensions practitioners may experience. The chapter concludes by reflecting on the future direction of community engagement given its positioning.

Assessing learning outcomes for students who are d/Deaf or hard of hearing presents ongoing challenges given the largely verbal nature of classrooms and the presentation of information. Educators should carefully consider several factors when assessing their students who are d/Deaf or hard of hearing. Those factors include, but are not limited to: the format of the assessment, the format in which the student is expected to respond, classroom acoustics, as well as how to continue monitoring learning outcomes based on classroom instruction.

We issue a double Souvenir number of The Library World in connection with the Library Association Conference at Birmingham, in which we have pleasure in including a special article, “Libraries in Birmingham,” by Mr. Walter Powell, Chief Librarian of Birmingham Public Libraries. He has endeavoured to combine in it the subject of Special Library collections, and libraries other than the Municipal Libraries in the City. Another article entitled “Some Memories of Birmingham” is by Mr. Richard W. Mould, Chief Librarian and Curator of Southwark Public Libraries and Cuming Museum. We understand that a very full programme has been arranged for the Conference, and we have already published such details as are now available in our July number.

Governance initiatives based on rankings are predicated on the possibility of making companies compete for the achievement of social goals by means of public comparisons of performance. The public of such performance – the ranker and various stakeholders in whose name the ranker speaks – thus fulfills the role of a “third party” whose favor is sought by competitors in what Simmel analyzed as “pure” or “indirect” competition. Yet little is known about how rankers seek to produce or entice such favor in order to enact competition. Through the case of the Access to Medicine Index, we examine the process of selective foregrounding, enticing and orchestration of different stakeholders through the gearing of the ranking’s information infrastructure aimed at optimizing the type and intensity of the competitive pressure exercised on the ranked. We illustrate how the ranker segments the public into different third parties, some well-identified stakeholders alongside a more anonymous audience. We find that stakeholders perceived as wielding legitimate power in the eyes of companies (such as investors) are actively equipped with the tools to witness competition, whereas stakeholders seen as powerful but involved in an agonistic relation with the companies (such as radical Non-Governmental Organizations) are discretely groomed at a distance, while those stakeholders with no perceived power over companies tend to remain unequipped. Whilst the gaze of stakeholders as third parties is differentiated along the lines of a hierarchy of observations, the voice of stakeholders as representatives of different interests is equalized and unified so as to adhere to an ideal of consensus. We reflect on how the needs of competition and those of stakeholder representation come to intersect in the particular governance space of access to medicine. Competition, far from being the automatic consequence of rankings, emerges as a contrived and laborious enactment requiring painstaking attention to publics and their selective equipment as third parties. Understanding the modes of such enactment is thus crucial for appreciating rankings’ governance outcomes.
