Abstract An increasing number of papers in the field of adhesion have been appearing in Rubber Chemistry & Technology. In the period 1941–1950 twenty-two papers appeared in this Journal covering various aspects of adhesion, whereas in the year 1959 alone eleven papers appear. The Rubber Division Library at the University of Akron has compiled bibliographies as follows: Bibliography # 10, “Use of Synthetic Resins in Natural and Synthetic Rubbers”, covering the period 1930–1952; Bibliography # 18, “Rubber to Metal Bonding”, in two parts, one covering the period 1937–1954 and a supplement covering 1955–1958; and Bibliography #20, “Reclaim Rubber Cements”, covering the period 1927–1954. In addition, special bibliographies were prepared covering the period 1949–1958 on the subjects “Rubber to Wood Adhesives”, “Rubber to Fabric Adhesives”, “Bonding of Polyurethanes”, “Metal to Metal Adhesives”, and “Chemistry of Rubber Adhesives”. The most comprehensive text in the field is “Adhesion and Adhesives” edited by N. A. DeBruyne and R. Houwink. More limited in scope are “Adhesive Bonding of Metals” by Epstein, “Adhesives for Wood” by Knight, “Adhesive Bonding of Reinforced Plastics” by Perry. Also “Rubber to Metal Bonding” by Buchan, which stresses the brass plating technic. Skeist has recently edited a “Handbook of Adhesives”. The Encyclopedia of Chemical Technology contains articles on “Adhesives” in Volume I and the First Supplement Volume. Various symposia have been sources of worthwhile papers on adhesion. The Division of Paint, Plastics, and Printing Ink Chemistry, ACS, published such papers in their preprint booklets, volume XV, No. 1 (1955) and volume XX, No. 1 (1960). Papers given at this division's “Recent Advances in Adhesives” symposium in 1957 are also published. Publication of papers at two symposia held in 1952 (Society of The Chemical Industry, London; Case Institute of Technology, Cleveland) form a valuable collection. Papers from The Second International Congress of Surface Activity in London in 1957 are also published. Papers from a Symposium on Adhesion held by the Society of Rheology in 1959 are published in volume IV of the Society's Transactions. General review articles on adhesion with extensive bibliographies were published as follows : Rinker-Kline “Survey of Adhesives and Adhesion; Kline-Reinhart “Fundamentals of Adhesion”; Brantley-Charnell “Investigation of the Nature of Forces of Adhesion”; Reinhart-Callomon “Survey of Adhesion and Adhesives” and Rutzler “Types of Bonds Involved in Adhesion”. The Reinhart-Callomon survey is quite extensive in its bibliography.

This article deals with the problem of insulating measuring weirs to avoid ice disturbances. The development of a simple method for insulating a conventional V-weir is described. This method will serve its purpose in many cases. For more difficult cases a special type of a fully insulated weir is described. The experiments described were carried out by The Division of Hydraulic Engineering, The University of Trondheim, The Norwegian Institute of Technology, at the River and Harbour Laboratory of the University, and at the IHD representative basin Sagelva.

Disaster Narratives

This document is an output from the “Voices After Disaster: narratives and representation following the Kerala floods of August 2018” project supported by the University of East Anglia (UEA)’s GCRF QR funds. The project is carried out by researchers at UEA, the Indian Institute for Human Settlements (IIHS), the Indian Institute of Technology (IIT), Bombay, and Canalpy, Kerala. In this briefing, we provide an overview of some of the emerging narratives of recovery in Kerala and discuss their significance for post-disaster recovery policy and practice. A key part of the work was a review of reported recovery activities by government and NGOs, as well as accounts and reports of the disaster and subsequent activities in the media and other information sources. This was complemented by fieldwork on the ground in two districts, in which the teams conducted a total of 105 interviews and group discussions with a range of community members and other local stakeholders. We worked in Alleppey district, in the low-lying Kuttanad region, where extreme accumulation of floodwaters had been far in excess of the normal seasonal levels, and in Wayanad district, in the Western Ghats, where there had been a concentration of severe flash floods and landslides.

Century Science

William Barton Rogers, conceptual founder of the Massachusetts Institute of Technology, pursued two interrelated careers in nineteenth-century America: one centered on his activities in science and the other on his higher educational reform efforts. His scientific peers knew him as a geologist and natural philosopher, director of the first geological survey of Virginia, author of over one hundred publications in science, and promoter of professionalization. His colleagues in higher education, meanwhile, thought of him as the reform-minded professor at the College of William and Mary and the University of Virginia, who later left the South and established one of America's first technological institutes. Comparatively little has been written about either of these areas of Rogers's life and career. We know much more about the scientific and educational thought of such figures as Louis Agassiz at Harvard, Benjamin Silliman at Yale, Joseph Henry at Princeton, and Alexander Dallas Bache at the helm of the Coast Survey. The literature on Rogers, by comparison, has offered little insight into his life and even less about his relationship to broader developments in nineteenth-century science and higher learning.

Chapter 5 explores what happened when women approached existing coeducational schools offering restricted gifts to benefit women. These donations either forced a school to open its doors to women or increased the number of women admitted by providing scholarships for women or erecting a women’s building or a women’s dormitory. Like the college founders, these donors believed that women were capable of the same intellectual achievement as men but found that many of America’s best universities resisted coeducation. The women in this chapter, including Mary Garrett, and Phoebe Hearst and the gifts they gave show how money could be wielded to force changes that would benefit women, in the form of access to education and professions formerly restricted to men. Moreover, coeducation at these schools, including Johns Hopkins, Massachusetts Institute of Technology, and the University of California, Berkeley, was especially significant. If women were welcomed at these important institutions, they could demonstrate their intellectual and professional capabilities and equality with men.

ETH World is a strategic initiative for establishing a new virtual campus at the Swiss Federal Institute of Technology (ETH) Zurich. ETH World will provide services in the areas of research, teaching, learning and infrastructure for the established disciplines in technology and natural science at ETH. The initiative aims to develop the excellence of ETH Zurich, making use of the new facilities and infrastructure instruments and methods that technological development offers. It is an integral part of the university, supporting its academic planning, infrastructure and financing processes. In its first part this paper describes the background of ETH World and an international conceptual competition organized in 2000 to seek ideas for the “infostructure” of this new academic environment. Some results of the competition are presented along with other projects that have been launched as building blocks of ETH World. The second part looks in some detail at e-learning as one of the focal points of ETH World, presenting two cases studies in architecture and control engineering education.

Since five-membered ring ethers often do not show good selectivity on equilibration, single diastereomers are best formed under kinetic control. Aaron Aponick of the University of Florida demonstrated (Organic Lett. 2008, 10, 669) that under gold catalysis, the allylic alcohol 1 cyclized to 2 with remarkable diastereocontrol. Six-membered rings also formed with high cis stereocontrol. Ian Cumpstey of Stockholm University showed (Chem. Commun. 2008, 1246) that with protic acid, allylic acetates such as 3 cyclized with clean inversion at the allylic center, and concomitant debenzylation. J. Stephen Clark of the University of Glasgow found (J. Org. Chem. 2008, 73, 1040) that Rh catalyzed cyclization of 5 proceeded with high selectivity for insertion into Ha, leading to the alcohol 6. Saumen Hajra of the Indian Institute of Technology, Kharagpur took advantage (J. Org. Chem. 2008, 73, 3935) of the reactivity of the aldehyde of 7, effecting selective addition of 7 to 8, to deliver, after reduction, the lactone 9. Tomislav Rovis of Colorado State University observed (J. Org. Chem. 2008, 73, 612) that 10 could be cyclized selectively to either 11 or 12. Nadège Lubin-Germain, Jacques Uziel and Jacques Augé of the University of Cergy- Pontoise devised (Organic Lett. 2008, 10, 725) conditions for the indium-mediated coupling of glycosyl fluorides such as 13 with iodoalkynes such as 14 to give the axial C-glycoside 15. Katsukiyo Miura and Akira Hosomi of the University of Tsukuba employed (Chemistry Lett. 2008, 37, 270) Pt catalysis to effect in situ equilibration of the alkene 16 to the more stable regioisomer. Subsequent condensation with the aldehyde 17 led via Prins cyclization to the ether 18. Paul E. Floreancig of the University of Pittsburgh showed (Angew. Chem. Int. Ed. 2008, 47, 4184) that Prins cyclization could be also be initiated by oxidation of the benzyl ether 19 to the corresponding carbocation. Chan-Mo Yu of Sungkyunkwan University developed (Organic Lett. 2008, 10, 265) a stereocontrolled route to seven-membered ring ethers, by Pd-mediated stannylation of allenes such as 21, followed by condensation with an aldehyde.
