The composition and corrosion behaviors of recycled and virgin Pb anode were investigated in industrial zinc electrowinning solution with different methods. The purpose of this study is the illustration of good anticorrosion activity of virgin Pb anodes compared to recycled one in industrial operation, while the compositions of both of them are the same which obtained from quantmetry method.
Its corrosion properties and electrocatalytic activity toward oxygen evolution reaction were appraised using potentiodynamic polarization, electrochemical impedance spectroscopy, galvanostatic polarization and ionic equilibrium methods. In addition, composition of anodes investigated with X-ray photoelectron spectroscopy (XPS) method. The surface composition of samples was studied via X-ray diffractogram (XRD).
The results indicate that the anodes display different anodic behaviors during the galvanostatic polarization. Virgin Pb anode shows a “potential reduction” about 320 mV lower than recycled Pb anode after 6 h of polarization; also, the stable potential after 72 h for virgin Pb anode is 100 mV lower than recycled Pb anode. Also, The XPS results show a trace amount of Cl in recycled anodes which cause the more corrosion activity. XRD results indicate that virgin Pb anodes have been covered by more oxides than recycled anodes after 72 h of electrowinning.
The treatment of corrosion behavior by virginity has not been detected by any researchers yet. Therefore, it is imperative to study the corrosion behavior and exact composition analysis of virgin and recycled Pb anodes to comprehension of them. This paper fulfills this need.

Since the mid‐1960s, people have begun to change their attitudes towards death and the role it plays in our society. Many find problems with the fact that an increasing number of people die in old age, afflicted with chronic diseases, and that a majority of people in the United States die in public institutions such as hospitals, extended care facilities, or convalescent homes. Questions have been raised regarding the extent to which technology should be used to keep someone alive, when doing so seems futile or even cruel. We are beginning to realize that our society at present does not deal effectively with this growing populaton of the aged.

FOR some years now air‐photography has been acknowledged as a most valuable accession to archaeological research. It has often been said, and with justice, that for the excavation of an ancient site an air‐photograph is practically a necessity. The reason for this is that, when seen from above, the plan of an archaeological site is revealed in a way which is impossible for an observer on the ground. The actual process differs according to the character of the ground itself. Ancient ruins consist either of earthworks, such as banks and ditches, or of foundations of masonry. In either case, the plan appears to a ground observer as a confused jumble that, when seen from above, is revealed for what it really is. Archaeologists have not many opportunities for flying themselves, at any rate in England, where this new branch of study originated and where it has been developed to a far greater extent than abroad. The pilot naturally has other things to think about when he is flying, and it has been suggested that a few words of explanation might be of interest to readers of Aircraft Engineering. There is a fine field here for the owner of a light aeroplane who might welcome some excuse for cross‐country flying, other than the obvious ones. Old England seen from the air is a book that has as yet only been half‐opened; there are still immense possibilities. In order to bring out some of the ways in which air‐photography works, I have described in this article a few typical air‐photographs of sites in Sussex.

Recreational travel is a psychological experience. Therefore, recreational travel involves an individual traveler's subjective perception of an actual or imagined activity in which he or she participates at a given time. In order to serve effectively recreation travelers at their destinations, it is essential for an agency dealing in recreation at the destinations to understand the psychological forces and factors that motivate and satisfy individual travelers.

Recent institutional scholarship has discovered new possibilities for change in both the accumulation of incremental transformations and in the skillful action, institutional work, and creative activities of political and institutional entrepreneurs. Lurking behind stability and change lie actors who can act reflexively within and with existing institutions, and who do so on a routine, rather than exceptional basis, redeploying, recombining, and transposing extant systems to solve problems of identity and control. This paper probes the potentials and limits of those possibilities – and the prospects for reform in American banking – via a case study of the Bank of North Dakota and efforts to transpose its hybrid model of state and community logics into other states. The analysis first finds a full range of institutional labors and skillful activities emphasized by recent work as the foundation for transposition. It finds crisis; the presence of multiple logics; the mobilization of boundary spanning networks; the use of conferences and theorization to sustain independent discourse and collective identities; skillful framing; and substantial editing and recombination to fit the model with receiving states’ institutions. It then juxtaposes these conditions with outcomes in the states, developing some implications for actor-centered institutionalisms, current preoccupations with mechanisms, and state-level strategies for financial reform.
WE begin a New Year in circumstances far removed from those in which any former year began. We were at war last January, it is true, but the actuality of it had not advanced over our own threshold as it has since done. The history of 1940 from our library viewpoint must await the assessment of more tranquil times, but in the cardinal tests to which libraries have been subjected we are convinced that they have been proven good. Fortunes have varied from the total destruction—except for 20,000 salvaged reference books—of the Gulson Library at Coventry to the loss of some glass or ceilings in other towns, but everywhere there has been remarkable resilience and an attempt, nearly always successful to restart the library service with little or no interruption. And the public has been most appreciative as letters we have seen prove: Richmond even received a congratulatory telegram from a reader. The contrast in this war between the desire for libraries and the continuous spurious economy “council” and “press” attacks upon them in the last one has been a significant social phenomenon.

The purpose of the paper is to show how The Spectator Project was developed as a digital environment for the study of The Tatler (1709‐1711), The Spectator (1711‐14), and the eighteenth‐century periodical in general.
The project demonstrates the use of different file formats concluding that the DjVu file format is superior to other formats for the purposes of this project.
The research finds that format, style, and even the content of The Tatler and The Spectator were closely imitated in some periodicals in Europe and the Americas.
The Spectator Project allows users to compare periodicals from this era available on the same site. This environment presents page images and the corresponding text, which allows users not only to view the actual pages, but also to use search and concordance tools.
Numerous scholarly web projects make their material simply and widely available but this project will also link relevant material and provide an interpretive editorial apparatus based on the special capabilities of the digital environment.

This investigation/report/reflection was motivated largely by the occasion of the first Centre for Social and Environmental Accounting Research (CSEAR) “Summer School” in North America.1 But its roots reach down as well to other recent reflection/investigation pieces, in particular, Mathews (1997), Gray (2002, 2006), and Deegan and Soltys (2007). The last of these authors note (p. 82) that CSEAR Summer Schools were initiated in Australasia, at least partly as a means to spur interest and activity in social and environmental accounting (SEA) research. So, too, was the first North American CSEAR Summer School.2 We believe, therefore, that it is worthwhile to attempt in some way to identify where SEA currently stands as a field of interest within the broader academic accounting domain in Canada and the United States.3 As well, however, we believe this is a meaningful time for integrating our views on the future of our chosen academic sub-discipline with those of Gray (2002), Deegan and Soltys (2007), and others. Thus, as the title suggests, we seek to identify (1) who the SEA researchers in North America are; (2) the degree to which North American–based accounting research journals publish SEA-related research; and (3) where we, the SEA sub-discipline within North America, might be headed. We begin with the who.

This study examines possible influences on the level of collaboration in published research by the most productive authors of accounting literature. Understanding the collaboration tendencies of these authors should benefit early-career-stage accounting faculty. Seven factors are examined for the publications of 93 of the most productive accounting authors. These productive authors are found to include fewer coauthors on their publications early in their careers. The number of coauthors increases through their first 16 to 17 years and then decreases through the remainder of their careers. The results also indicate that productive accounting researchers include a greater number of coauthors on more recently published articles and on longer articles. Fewer coauthors are included when a productive author is affiliated with a “top-10” university or on articles published in highly ranked accounting journals. Lastly, the results show that prolific authors seek out coauthorship throughout their careers and usually include one or more coauthors on their publications. Implications from these results and specific suggestions for accounting faculty are discussed.
