Wet and dry deposition of 129I in Seville (Spain) measured by accelerator mass spectrometry

Iodine-129 (Full-size image (<1 K)) concentrations have been determined by accelerator mass spectrometry in rainwater samples taken at Seville (southwestern Spain) in 1996 and 1997. This technique allows a reduction in the detection limits for this radionuclide in comparison to radiometric counting and other mass spectrometric methods such as ICP-MS. Typical 129I concentrations range from 4.7×107129I atoms/l (19.2%) to 4.97×109129I atoms/l (5.9%), while 129I depositions are normally in the order of 108–1010 atoms/m2 d. These values agree well with other results obtained for recent rainwater samples collected in Europe. Apart from these, the relationship between 129I deposition and some atmospheric factors has been analyzed, showing the importance of the precipitation rate and the concentration of suspended matter in it.

Characterisation of flash floods in small ungauged mountain basins of Central Spain using an integrated approach

One of the main problems of flood hazard assessment in ungauged or poorly gauged basins is the lack of runoff data. In an attempt to overcome this problem we have combined archival records, dendrogeomorphic time series and instrumental data (daily rainfall and discharge) from four ungauged and poorly gauged mountain basins in Central Spain with the aim of reconstructing and compiling information on 41 flash flood events since the end of the 19th century. Estimation of historical discharge and the incorporation of uncertainty for the at-site and regional flood frequency analysis were performed with an empirical rainfall–runoff assessment as well as stochastic and Bayesian Markov Chain Monte Carlo (MCMC) approaches. Results for each of the ungauged basins include flood frequency, severity, seasonality and triggers (synoptic meteorological situations). The reconstructed data series clearly demonstrates how uncertainty can be reduced by including historical information, but also points to the considerable influence of different approaches on quantile estimation. This uncertainty should be taken into account when these data are used for flood risk management.

Quantification of Mitral Regurgitation with Multiple Jets: In Vitro Comparison of Two-dimensional PISA techniques

Purpose: Traditionally, the proximal isovelocity surface area (PISA) is based on the assumption of a single hemisphere (hemispheric PISA), but this technique has not been validated for the quantification of mitral regurgitation (MR) with multiple jets. Methods: The left heart simulator was actuated by a pulsatile pump at various stroke amplitudes. The regurgitant volume (Rvol) passing through the mitral valve phantoms with single and double regurgitant orifices of varying size and interspace was quantified by a flowmeter as reference technique. Color Doppler 3-D full-volumes were obtained, and Rvol were derived from 2-D PISA surfaces on the basis of hemispheric and hemicylindric assumption with one base (partial hemicylindric PISA) or 2 bases (total hemicylindric PISA). Results: 72 regurgitant volumes (Rvol range: 8 to 76 ml/beat) were obtained. Hemispheric PISA Rvol correlated well with reference Rvol by one orifice (R²=0.97; bias -2.7±3.2ml), but less by ≥ one orifice (R²=0.89). When a fusion of two PISAs occured, addition of two hemispheric PISA overestimated Rvol (bias 9.1±12.2ml, fig.1), and single hemispheric PISA underestimated Rvol (bias -12.4±4.9ml). If an integrated approach was used (hemispheric in single orifice, total hemicylindric in two non-fused PISAs and partial hemicylindric in two fused PISAs), the correlation was R²=0.95, bias -1.6±5.6ml (fig.2). In the ROC analysis, the cutoff to detect ≥ moderate-to-severe Rvol (≥45ml) was 42ml (AUC 0.99, sens. 100%, spec. 93%). Conclusions: In MR with two regurgitant jets, the 2-D hemicylindric assumption of the PISA offers a better quantification of Rvol than the hemispheric assumption. Quantification of MR using 2-D PISA requires an integrated approach that considers number of regurgitant orifices and fusion of the PISAs.

Renewal of Religious Leadership According to an Ancient Model. Bishop Joseph Hubert Reinkens and Bishop Martin of Tours

Im Jahr 1866 verfasste der damals in Breslau lehrende römisch-katholische Kirchenhistoriker Joseph Hubert Reinkens eine der ersten historisch-kritischen Studien in deutscher Sprache über Martin von Tours, in der er sich u.a. mit Martins bischöflichem Leitungsdienst befasste. Nach dem Ersten Vatikanischen Konzil (1870) wurde Reinkens 1873 der erste Bischof für die Alt-Katholiken im Deutschen Reich. Der Beitrag beschreibt den Einfluss, den Reinkens' Martin-Rezeption auf sein theologisches und praktisches Verständnis des Bischofsamts hatte.

The Role of the European Imperial Powers throughout the Armenian Schism in the 1870s

The Bull "Reversurus" (1867) and its dogmatic legitimization at the First Vatican Council in 1870 caused not only ecclesiastical controversy and Schism in the Armenian Catholic Church, but it had also wide political consequences for the Armenian Catholics in the Ottoman Empire. The conflict originally between the Armenian Catholics and Rome attracted very soon the attention of the European imperial Powers. France, the British Empire, the German Empire, Austria-Hungary and Russia were the main political powers who were involved in the Armenian affair. A full picture of the role of all these powers for the course of the Armenian Schism is missing. Mostly the role of France is foregrounded in the printed sources, as the main power, which supported the papacy to win during the Armenian affair. The role and the motives of the other imperial powers is almost missing. This article will try to describe as completely as possible the historical and political background, which brought to the escalation of the Armenian conflict beyond the national frontiers and led to number of conflicts at the international and transnational level. It will be shown that the imperial policy in Europe in the 19th century have played an enormous role throughout the Armenian Schism. It will be explained that several historical circumstances in Europe, especially the relation of the European imperial powers to each other as well as their expectations from the Ottoman Empire and its Armenian subjects were decisive for the duration and conclusion of the Armenian Schism.

A longitudinal study of Besnoitia besnoiti infections and seasonal abundance of Stomoxys calcitrans in a dairy cattle farm of southwest France

Bovine besnoitiosis, caused by the cyst-forming apicomplexan Besnoitia besnoiti, is commonly reported in some restricted regions of South-Western Europe, and in larger regions of Africa and Asia. This infection is thought to be transmitted by blood feeding insects and is responsible for major economic losses in cattle production. A recent emergence in Europe, notified in the Centre of France, Spain and Germany, has attracted more attention to this disease. Clinical signs could appear in some animals; however, many infected cattle remain asymptomatic or show scleral-conjunctival cysts (SCC) only. Recent development of serological methods allows carrying out seroepidemiological field studies. In this respect, a long-term investigation was performed in a dairy cattle farm localized in an enzootic area of besnoitiosis of South-western France between March 2008 and May 2009. The objective was to estimate the seasonal pattern of B. besnoiti infections based on the presence of SCC and serology (ELISA and Western blot). In parallel, an entomological survey was conducted to describe population dynamics of Stomoxys calcitrans and Tabanidae species. The seroprevalence determined by Western blot in a cohort of 57 animals continuously present during the whole survey increased from 30% in March 2008 to 89.5% in May 2009 and was always higher than the prevalence based on clinically assessed SCC. New positive B. besnoitia seroconversions occurred throughout the year with the highest number in spring. In addition, many seroconversions were reported in the two months before turn-out and could be associated with a high indoors activity of S. calcitrans during this period.

Die katholische Kirche und Moralpolitik in Österreich: Reformdynamiken in der Regulierung von Schwangerschaftsabbrüchen und der Anerkennung gleichgeschlechtlicher Partnerschaften

Eine vergleichende Analyse der Regulierung von Schwangerschaftsabbrüchen und gleichgeschlechtlichen Partnerschaften in Westeuropa im Zeitraum von 1960 bis 2010 zeigt, dass katholisch geprägte Staaten diese Bereiche grundsätzlich nicht weniger stark liberalisiert haben als andere Länder. Allerdings drosselt der Katholizismus offensichtlich die Geschwindigkeit von Reformprozessen. Auf Basis einer detaillierten explorativen Analyse der Politikentwicklungen in Österreich, das sehr früh die Gesetzgebung zum Schwangerschaftsabbruch lockerte, jedoch bei der Einführung registrierter homosexueller Partnerschaften lange zögerte, leiten wir induktiv theoretische Implikationen ab: Die katholische Kirche kann permissive Reformen so lange verhindern, wie institutionelle und kulturelle Gelegenheitsstrukturen nicht der säkular-liberalen Opposition behilflich sind, erfolgreiches Agenda-Setting zu betreiben und Mehrheiten für einen Politikwechsel zu gewinnen.
