Jean-François Saliège passed away on Friday, 1 June 2012, following a heart attack at age 68. Jean-François was born in Chartres and spent his entire career in Paris, a city that he particularly enjoyed. He was hired in 1965 as a junior technician at the Laboratoire de Géologie Dynamique de la Faculté des Sciences de Paris at La Sorbonne University (Director Louis Glangeaud), where he participated in the creation of the radiocarbon and mass spectrometry laboratory under supervision of René Létolle, Jean-Charles Fontes, and Colette Vergnaud-Grazzini. In 1975, he moved to the University of Paris VI and worked more specifically with J-C Fontes in the 14C laboratory as an engineer. In 1981, he helped J-C Fontes to create the Hydrology and Isotope Geochemistry lab at Orsay University. The following year, he returned to the University of Paris VI and joined the team led by Colette Vergnaud-Grazzini at the Laboratoire de Géologie Dynamique, where Jean-François set up the new stable isotope and radiocarbon lab. Between 1990 and 2008, he continued to work at the University of Paris VI at the LODYC lab (Dir. Lilianne Merlivat), then at the LOCEAN lab (Dir. Laurence Eymard) on Catherine Pierre's team.

<p>A silver phosphate comparison material (Ag<sub>3</sub>PO<sub>4</sub>) for measurement of the stable oxygen isotope composition was prepared by the University of Natural Resources and Life Science (BOKU) and distributed to four international isotope laboratories frequently measuring the δ<sup>18</sup>O value in Ag<sub>3</sub>PO<sub>4</sub>. The contributing laboratories were the University of Natural Resources and Life Science (BOKU), The University of Western Australia (UWA), the ETH Zurich (ETH), the University of Helsinki (UH) and the Helmholtz Centre for Environmental Research (UFZ). Each laboratory analysed the comparison material in a minimum of two independent measuring rounds with a minimum of 10 individual measurements. The instrument used to perform the measurements were high-temperature conversion elemental analyzers coupled with continuous flow isotope ratio mass spectrometers: TC/EA with Thermo Finnigan Delta XP (BOKU), a TC/EA with a Thermo Scientific Delta V Plus (UWA), an Elementar Pyrocube with a Isoprime 100 (ETH), a Flash IRMS EA with a Thermo Scientific Delta V Plus (UH) and a TC/EA with a Finnigan Delta S (UFZ). The working gas δ<sup>18</sup>O was set to 0 ‰ and the normalization was done by a three-point linear regression calibration (Paul et al., 2007) using the reference material IAEA-601 (δ<sup>18</sup>O<sub>VSMOW</sub> = +23.14 ± 0.17 ‰), IAEA-602 (δ<sup>18</sup>O<sub>VSMOW</sub> = +71.28 ±0.42 ‰) (both benzoic acid) and NBS 127 (barium sulfate) (δ<sup>18</sup>O<sub>VSMOW</sub> = +8.59 ± 0.20 ‰) (Brand et al., 2009). BOKU, UH and ETH had experienced inhomogeneity of the IAEA-602 as already mentioned in Brand et al. (2009). The weighted arithmetic mean and standard deviation (1σ) of the new BOKU Ag<sub>3</sub>PO<sub>4</sub> comparison material from the single measurements has a δ<sup>18</sup>O value of 13.80 ± 0.40 ‰ on the VSMOW scale (n=131), while the median of the single rounds was 13.76 ‰ (n=11) and the median of the laboratories was 13.79 ‰ (n=5). The arithmetic means of two measuring rounds were outside ± 1σ. When excluding data from these rounds from the statistics the weighted arithmetic mean has a δ<sup>18</sup>O value of 13.80 ± 0.32 ‰ on the VSMOW scale (n = 111) and the median of the single valid rounds (n=9) remained at 13.76 ‰ and the median of the labs at 13.79 ‰ (n=5). Excluding NBS127 from the normalization slightly reduced the δ<sup>18</sup>O value to 13.74 ± 0.31 ‰ (n = 111). The BOKU Ag<sub>3</sub>PO<sub>4</sub> comparison material is available for stable isotope research laboratories to facilitate the calibration of their lab comparison material.</p><p> </p><p>Brand, W.A., Coplen, T.B., Aerts-Bijma, A.T., Böhlke, J.K., Gehre, M., Geilmann, H., Gröning, M., Jansen, H.G., Meijer, H.A.J., Mroczkowski, S.J., Qi, H., Soergel, K., Stuart-Williams, H., Weise, S.M., Werner, R.A., 2009.

This paper describes the creation of Florida Universitaria CRAI’s Catálogo de la mujer. Florida is an educational cooperative set up in the region of Valencia in the 1970s, a time when many projects were launched in an attempt to change and modernize approaches to teaching. Since its inception, the values that have underpinned its work have been a management style based on democratic practices, secularism, the promotion of the Valencian language and coeducation, and the application of the Mondragón business model. These values have also shaped the creation of the bibliographical archives belonging to the CRAI-Bibilioteca and the rest of the cooperative’s libraries. Since the first professional training programmes in 1977-1978, the cooperative has adapted the courses on offer to the needs of its public (and also in line with its budget). Florida Universitària came into being in the early 1990s, as an associated centre attached to the Valencia’s two main universities (the University of Valencia and the Polytechnic University). Finally, the language centre was founded in 1994. La Florida is based in Catarroja, a town in the Horta Sud of Valencia, where secondary school studies, language teaching and university courses are taught at three different sites. These centres were created at different stages of the cooperative’s history, building on the original secondary school and expanding to cover the teaching needs of a group of villages located some way away from the city, and responding to the rising demands of the area’s industrial sector.

Two independent programs have collected and analyzed atmospheric CO2 samples from Point Barrow, Alaska, for radiocarbon content (Δ14C) over the period 2003–2007. In one program, flask collection, stable isotope analysis, and CO2 extraction are performed by the Scripps Institution of Oceanography's CO2 Program and CO2 is graphitized and measured by accelerator mass spectrometry (AMS) at Lawrence Livermore National Laboratory. In the other program, the University of California, Irvine, performs flask collection, sample preparation, and AMS. Over 22 common sample dates spanning 5 yr, differences in measured Δ14C are consistent with the reported uncertainties and there is no significant bias between the programs.

Abstract. In the last few decades and in the near future CO2-induced ocean acidification is potentially a big threat to marine calcite-shelled animals (e.g. brachiopods, bivalves, corals and gastropods). Despite the great number of studies focusing on the effects of acidification on shell growth, metabolism, shell dissolution and shell repair, the consequences for biomineral formation remain poorly understood. Only a few studies have addressed the impact of ocean acidification on shell microstructure and geochemistry. In this study, a detailed microstructure and stable isotope geochemistry investigation was performed on nine adult brachiopod specimens of Magellania venosa (Dixon, 1789). These were grown in the natural environment as well as in controlled culturing experiments under different pH conditions (ranging from 7.35 to 8.15±0.05) over different time intervals (214 to 335 days). Details of shell microstructural features, such as thickness of the primary layer, density and size of endopunctae and morphology of the basic structural unit of the secondary layer were analysed using scanning electron microscopy. Stable isotope compositions (δ13C and δ18O) were tested from the secondary shell layer along shell ontogenetic increments in both dorsal and ventral valves. Based on our comprehensive dataset, we observed that, under low-pH conditions, M. venosa produced a more organic-rich shell with higher density of and larger endopunctae, and smaller secondary layer fibres. Also, increasingly negative δ13C and δ18O values are recorded by the shell produced during culturing and are related to the CO2 source in the culture set-up. Both the microstructural changes and the stable isotope results are similar to observations on brachiopods from the fossil record and strongly support the value of brachiopods as robust archives of proxies for studying ocean acidification events in the geologic past.

Religious Fervor

By the witness of history, the indebtedness of higher learning to religious fervor is very great. This aspect of education deserves at least as much attention as the retardation and perversion of learning by religious bigotry. The latter is, as we all know, most frequently and loudly stressed today. Again, we hear little of the fact that periods when learning has been gradually secularized have been periods when scholarship grew lax and knowledge halted; until a new impulse of religious conviction re-vivified both the souls and the minds of scholars, with the restilt that academies and universities pulsed with fresh enthusiasm and notable advancement in learning took place. But of many instances of this phenomenon the mention of Abailard and the University of Paris, Wyclif and Oxford, Luther and Wittenberg, Cartwright and Emmanuel, Wolff and Halle, Fichte and Berlin, must suffice. Yet none is more illustrative of our conclusions than Harvard, the creation of the Congregational Puritanism of William Ames.

RESUMO        Do nascimento da Associação Internacional de Teatro na Universidade, ou Quando uma necessidade do TU cria o órgão AITUDesde a criacão das primeiras universidades na Idade Média, a atividade teatral universitária esteve diretamente ligada às matérias ensinadas como um auxiliar do ensino,  e essencialmente praticada intra muros. Após a 2a. guerra mundial (1945), o teatro universitário iria acentuar o fenômeno de sua abertura e de sua internacionalização. Rompendo os muros da universidade, o teatro conquistaria cada vez mais visibilidade, e inúmeros grupos universitários se veriam tentados pela profissionalização. A própria universidade vai, a partir daí, considerar o teatro como objeto de estudo.  E os anos 70 serão, assim, marcados em quase todas as universidades europeias, pela criação de Departamentos de Estudos Teatrais. A década de 1980 viu florescerem novos festivais internacionais que revelam claramente a abundância de teatros universitários e a grande diversidade de suas práticas. Por ocasião dos Encontros de Liège (RITU), vai ressurgir no início dos anos 90, a questão da definicão do teatro universitário, que impulsiona os liegenises a organizar um Congresso Mundial em outubro de 1994, quando foi criada a Associação Internacional do Teatro na Universidade. A AITU organzia seu 11o. Congresso em 2016 em Manizales (Colombia). Palavras chave :  AITU-IUTA, Teatro Universitário, História do Teatro Universitário   ABSTRACT On the birth of the International University Theatre Association, or When a need of UT creates the organ IUTASince the creation of the first universities in the Middle Ages, the university theater activity was considered as a teaching aid to the subjects taught, and was primarily practiced intra muros. After the 2nd World War (1945), University Theatre would accentuate the phenomenon of openness and internationalization. Leaving the walls of the university, theater acquired more and more visibility, and numerous academic troops were tempted by professionalization. The university itself will now consider theater as a case study. And so the 70’s will be marked by the creation of Theater Studies Departments in universities all over Europe. The 1980’s saw a flowering of new international festivals which clearly reveal the abundance of university theaters and the great diversity of practices. On the occasion of the Liège Meetings (RITU), the question of the definition of university theater resurfaced in the early 90s, which pushed the organizers to set up a World Congress in October 1994. This led to the creation of the International University Theatre Association.  The IUTA holds its 11th Congress in 2016 in Manizales (Colombia).  Keywords:   AITU-IUTA, University Theatre, History of University Theatre

In contrast to the inability of x-ray microanalysis to detect Li, secondary ion mass spectrometry (SIMS) generates a very strong Li+ signal. The latter’s potential was recently exploited by Williams et al. in the study of binary Al-Li alloys. The present study of Al-Li-Cu was done using the high resolution scanning ion microprobe (SIM) at the University of Chicago (UC). The UC SIM employs a 40 keV, ∼70 nm diameter Ga+ probe extracted from a liquid Ga source, which is scanned over areas smaller than 160×160 μm2 using a 512×512 raster. During this experiment, the sample was held at 2 × 10-8 torr.In the Al-Li-Cu system, two phases of major importance are T1 and T2, with nominal compositions of Al2LiCu and Al6Li3Cu respectively. In commercial alloys, T1 develops a plate-like structure with a thickness <∼2 nm and is therefore inaccessible to conventional microanalytical techniques. T2 is the equilibrium phase with apparent icosahedral symmetry and its presence is undesirable in industrial alloys.
