„Es ist keine Zeit mehr.“ Als ich sie diese Worte zum ersten Mal sagen hörte, wurden sie ganz beiläufig erwähnt, mit einem flüchtigen Blick gen Himmel, als ob jeden Moment Regen fallen könnte oder ...der Zeitpunkt gekommen wäre, in dem man einen bereits gefassten Plan endgültig aufgibt; genau von dieser Einstellung zeugten ihre Haltung, ihre Kleidung, ja sogar ihr Gesichtsausdruck, von einer Vernachlässigung und Lethargie, die wie in Zeitlupe auf der Schwelle unumkehrbaren Verwelkens schwankten: Nach diesem Satz rührte sich keiner, niemand sagte ein Wort, einen Augenblick lang standen halb leere Kaffeetassen und volle Aschenbecher vollkommen ruhig auf dem Tisch, als wären sie Versteinerungen einer Alltagsszene, die sich vor mehreren Jahrtausenden ereignet hatte, ein neues Herculaneum, überdeckt von einer unsichtbaren oder gänzlich durchsichtigen Masse eines anderen Vulkans und so für die Ewigkeit bewahrt, doch dieser Moment – so tief und unendlich er mir im Nachhinein auch scheint, wenn sich mein Blick wie jetzt in ihn versenkt, und so sehr er immer noch bereit ist, alles zu verschlingen, was von meinen Tagen blieb – dauerte nur eine Sekunde oder zwei: Jemand drehte sich um oder atmete aus, jemand zündete sich noch eine Zigarette an oder hob die Hand, um den Kellner zu rufen; ein sonniger Spätvormittag – der am Ende des Frühlings stets die Form einer gelbgrünen, collagenhaft gezeichneten Fläche annimmt, deren Elemente man nicht im Einzelnen ausmachen kann wie scharf umrissene Ausschnitte, sondern die sich in ein scheinbar beliebiges Getümmel verwandeln, eine Bewegung, die die Zeit, statt sie im Fluss zu halten, auf geheimnisvolle Weise zum Stehen bringt – begann sich in einen frühen Nachmittag hinzuziehen, in jenem Rhythmus, der so typisch ist für Osijek. Im Grunde genommen war überhaupt nichts passiert, zumindest kam es mir damals so vor.
Durch die schmutzige Fensterscheibe beobachtete er die Landschaften wie sie vorbeizogen. Der Zug machte das gleiche klappernde Geräusch wie immer, wie schon vor sechsundzwanzig Jahren, als er zum ...ersten Mal dieselben Kilometer hinter sich brachte. Er war damals zum Studieren gegangen, mit jenem schweren Lederkoffer, in den er nur mit viel Mühe all das hineingestopft hatte, was jemand mitnehmen würde, der davon überzeugt ist, dass er nie wiederkehrt – alles, was er nicht fremder Ungnade ausliefern konnte, einschließlich der dreihundertfünfundsechzig Briefe, die Tihana ihm während seines Militärdienstes nach Mazedonien geschickt hatte.
Sie nennen ihn Traktor. Nichts von dem, was er sieht oder hört, dringt zu ihm durch. Manchmal wacht er nachts auf und dann würde er am liebsten aus dem Haus gehen, in den Wald und verschwinden. Kurz ...gesagt, er ist verhaltensgestört und nimmt Tabletten.
(…) I could hardly agree more, in principle, with the Head of Department’s dilemma. Wary of what might follow, I replied promptly: “I hope you’re not considering a pay cut. My salary is already ...minimal. I don’t think it can possibly get any lower.” (…)

This article analyzes the representations of Infanta Elvira, the third child of King
Fernando I and Queen Sancha, in contemporary Spanish narrative. It aims to show that most
recent Spanish ...historical novels maintain the low relevance of Infanta Elvira in medieval
chronicles by either directly discarding her or by alluding to her through mainly vague
references. However, it is also noteworthy that current Spanish novel seems to be creating a new
picture of Infanta Elvira, portraying her as a fanatic or/and a lascivious woman. This final
outcome can be interpreted as entailing the oblivion of historical tradition and would in turn
make Infanta Elvira to function as the counter-image of his sister Urraca.
El presente estudio tiene como objeto analizar las representaciones de la infanta
Elvira, tercera de los hijos de Fernando I y de la reina Sancha, en la narrativa española
contemporánea. A partir del corpus estudiado, se pretende demostrar que la novela histórica de
las últimas décadas supone una consolidación de su escasa solidez cronística, al descartarla
directamente o apenas aludir a ella a través de vagas referencias, pero también que la literatura
de entre milenios ha forjado una nueva representación, entre el fanatismo o la lascivia, que obvia
la tradición y que se sustenta como imagen en negativo su hermana Urraca.
Nanoparticle in vitro toxicity studies often report contradictory results with one main reason being insufficient material characterization. In particular the characterization of nanoparticles in ...biological media remains challenging. Our aim was to provide robust protocols for two of the most commonly applied techniques for particle sizing, i.e. dynamic light scattering (DLS) and differential centrifugal sedimentation (DCS) that should be readily applicable also for users not specialized in nanoparticle physico-chemical characterization. A large number of participants (40, although not all participated in all rounds) were recruited for a series of inter-laboratory comparison (ILC) studies covering many different instrument types, commercial and custom-built, as another possible source of variation. ILCs were organized in a consecutive manner starting with dispersions in water employing well-characterized near-spherical silica nanoparticles (nominal 19 nm and 100 nm diameter) and two types of functionalized spherical polystyrene nanoparticles (nominal 50 nm diameter). At first each laboratory used their in-house established procedures. In particular for the 19 nm silica particles, the reproducibility of the methods was unacceptably high (reported results were between 10 nm and 50 nm). When comparing the results of the first ILC round it was observed that the DCS methods performed significantly worse than the DLS methods, thus emphasizing the need for standard operating procedures (SOPs). SOPs have been developed by four expert laboratories but were tested for robustness by a larger number of independent users in a second ILC (11 for DLS and 4 for DCS). In a similar approach another SOP for complex biological fluids, i.e. cell culture medium containing serum was developed, again confirmed via an ILC with 8 participating laboratories. Our study confirms that well-established and fit-for-purpose SOPs are indispensable for obtaining reliable and comparable particle size data. Our results also show that these SOPs must be optimized with respect to the intended measurement system (e.g. particle size technique, type of dispersant) and that they must be sufficiently detailed (e.g. avoiding ambiguity regarding measurand definition, etc.). SOPs may be developed by a small number of expert laboratories but for their widespread applicability they need to be verified by a larger number of laboratories.
Fumonisins, mycotoxins primarily produced by Fusarium verticillioides and Fusarium proliferatum, occur predominantly in cereal grains, especially in maize. The European Commission asked EFSA for a ...scientific opinion on the risk to animal health related to fumonisins and their modified and hidden forms in feed. Fumonisin B1 (FB1), FB2 and FB3 are the most common forms of fumonisins in feedstuffs and thus were included in the assessment. FB1, FB2 and FB3 have the same mode of action and were considered as having similar toxicological profile and potencies. For fumonisins, the EFSA Panel on Contaminants in the Food Chain (CONTAM) identified no‐observed‐adverse‐effect levels (NOAELs) for cattle, pig, poultry (chicken, ducks and turkeys), horse, and lowest‐observed‐adverse‐effect levels (LOAELs) for fish (extrapolated from carp) and rabbits. No reference points could be identified for sheep, goats, dogs, cats and mink. The dietary exposure was estimated on 18,140 feed samples on FB1–3 representing most of the feed commodities with potential presence of fumonisins. Samples were collected between 2003 and 2016 from 19 different European countries, but most of them from four Member States. To take into account the possible occurrence of hidden forms, an additional factor of 1.6, derived from the literature, was applied to the occurrence data. Modified forms of fumonisins, for which no data were identified concerning both the occurrence and the toxicity, were not included in the assessment. Based on mean exposure estimates, the risk of adverse health effects of feeds containing FB1–3 was considered very low for ruminants, low for poultry, horse, rabbits, fish and of potential concern for pigs. The same conclusions apply to the sum of FB1–3 and their hidden forms, except for pigs for which the risk of adverse health effect was considered of concern.
A wide variety of enzyme‐linked immunosorbent assays (ELISAs) are commercially available for gluten detection in food, including new formats and assays with antibodies against relevant gluten ...epitopes. Nevertheless, problems persist to accurately determine the gluten content of products. In this study, the performance of a set of 14 ELISA kits for gluten detection, representative of the current ELISA methods available on the market, was evaluated. These tests were used to determine gluten content in a series of relevant food matrices varying in complexity. Our results show that, currently, there is no single ELISA method that can accurately detect and quantify gluten in all different matrices. This includes the current type I method R5 as recommended by Codex Alimentarius. We conclude that further improvements are urgently needed and recommend focusing on competitive formats, improving extraction methods, and the detection of relevant gluten peptides (in order of priority).
