Il «Magazin« (1780-1782) spagnolo di Friedrich Justin Bertuch e il suo contesto
No full textLe pionieristiche ricerche di Dietrich Briesemeister hanno allargato il discorso dell’ispanistica nel senso dei transferts culturali attirando l’attenzione, in particolare, su Friedrich Justin Bertuch (1747-1822). Questo poliedrico imprenditore culturale trasforma Weimar in un importante centro di irradiazione della cultura spagnola in Germania. Il contributo in oggetto individua per la prima volta un preciso nesso fra l’identificarsi delle relazioni con l’Italia (culminate nel «Magazin der italienischen Litteratur und Künste» di Christian Joseph Jagemann, fondato nel 1780), l’operato di Christoph Gottlieb von Murr e il «Magazin der Spanischen und Portugiesischen Literatur» di Bertuch. Tutta basata su lettere inedite è la ricostruzione sia dei rapporti fra Bertuch e Murr, sia dei rapporti fra Bertuch e Christian Felix Weiße, editore fino al 1782 di una rivista sassone all’avanguardia nella diffusione della letteratura spagnola, la «Neue Bibliothek der schönen Wissenschaften und der freyen Künste».
Il filtro inglese risulta evidente nelle due imprese traduttive immediatamente precedenti al «Magazin», The History of the famous Preacher Friar Gerund de Campazas; otherwise Gerund Zotes (traduzione di Baretti) e la Historia del famoso predicador fray Gerundio de Campazas alias Zotes.
La caratterizzazione del «Magazin» e della sua eco sulle riviste tedesche coeve include la smentita (sempre in base a materiali inediti conservati nel fondo Bertuch del Goethe- und Schiller-Archiv di Weimar) della tesi di Heymann.
L’ampio contributo è concluso dall’analisi del Manual de la lengua española oder Handbuch der Spanischen Sprache in cui Bertuch usa i testi dei migliori poeti e prosatori spagnoli come eserciziario e dall’analisi della coeva traduzione del Nouveau voyage ou Tableau de l’etat actuel de cette Monarchie di Jean-François Bourgoing con il titolo Neue Reise durch Spanien vom Jahr 1782 bis 1788. Nel secondo volume di tale traduzione appare in appendice un trattatello Über den gegenwärtigen Zustand der Literatur in Spanien di Thomas Tychsen ove si constata l’inconsistenza dell’«opinio communis secondo cui la Spagna sarebbe un luogo delle tenebre e dell’ignoranza».
Il contributo offerto da G. Cantarutti e S. Ruzzenenti viene valutato in questi termini da José Checa Beltrán, responsabile del gruppo di ricerca sulle «lecturas del legado literario-cultural español» nell’Europa dei Lumi: «este capítulo [...] ilumina una compleja red de relaciones entre intelectuales de distintos países europeos y ofrece una rica mina de datos inéditos sobre traducciones, sinergias y autores que operaban en la Europa del siglo XVIII»
Periostracal mineralization in the gastrochaenid bivalve Spengleria
No full textWe investigated the spikes on the outer shell surface of the endolithic gastrochaenid bivalve genus Spengleria with a view to understand the mechanism by which they form and evaluate their homology with spikes in other heterodont and palaeoheterodont bivalves. We discovered that spike formation varied in mechanism between different parts of the valve. In the posterior region, spikes form within the translucent layer of the periostracum but separated from the calcareous part of the shell. By contrast those spikes in the anterior and ventral region, despite also forming within the translucent periostracal layer, become incorporated into the outer shell layer. Spikes in the posterior area of Spengleria mytiloides form only on the outer surface of the periostracum and are therefore, not encased in periostracal material. Despite differences in construction between these gastrochaenid spikes and those of other heterodont and palaeoheterodont bivalves, all involve calcification of the inner translucent periostracal layer which may indicate a deeper homology
Activation of peroxydisulfate and peroxymonosulfate by zero-valent iron and FeCu bimetals for 4-chlorophenol oxidation in water
No full textThis work systematically evaluates the application of disc-milled iron‐copper (FeCu) bimetals for activating peroxydisulfate (PDS) and peroxymonosulfate (PMS), providing insights into both systems behavior. 4-chlorophenol (4-CP) was chosen as the model pollutant to evaluate the performance of bimetals compared to traditional iron-based activators (Fe2+ and Fe0). The influence of different factors was addressed, including i) bimetals composition (0, 5, and 50 % Cu content), ii) disc-milling, and iii) bimetals concentration. FeCu bimetal with 5 % Cu content showed a better synergy when combined with PMS, resulting in the highest 4-CP degradation, dechlorination, and mineralization (92 %, 62 %, and 60 %, respectively, within 120 min). Different quenchers and PMSO were used to identify the main reactive species in the bimetallic systems, showing the production of Fe4+ with both oxidants and a relevant contribution of 1O2 in the case of PMS. Finally, practical considerations for implementing the FeCu systems have been carefully evaluated, including the potential secondary effects on water quality due to iron and copper release, as well as the stability and reusability of these activators. Adjusting the final pH to 8.0 effectively precipitated dissolved metals, ensuring compliance with Italian environmental quality standards (Fe ≤ 2 mg/L and Cu ≤ 0.1 mg/L). Moreover, Fe5Cu bimetals have shown outstanding stability in repeated uses. Thus, this study introduces a novel, and eco-friendly approach for synthesizing active FeCu bimetals capable of efficiently activating oxidants, offering a promising solution for environmental pollution remediation. While optimal treatment conditions are thoroughly discussed, further studies are needed for full-scale application

This study aimed to determine the occurrence and identity of tick-borne parasites (piroplasms and Hepatozoon spp.) in Navarre, one of the strongholds for wildcats in Spain. DNA was extracted from spleen samples of 63 road-killed wildcats and analyzed using a suite of molecular protocols targeting the 18S rRNA and CytB gene fragments. Eighty percent of the wildcats tested positive for at least one parasite. Cytauxzoon spp. was detected in 65 % of the individuals. Molecular characterization and phylogenetic analysis confirmed the presence of Cytauxzoon europaeus in nine samples, representing the first report of this species in the Iberian Peninsula. Hepatozoon spp. was found in 46 % of the wildcats, and molecular characterization of four cases identified Hepatozoon felis. Babesia vulpes was detected in a single individual. Coinfection with Cytauxzoon sp. and Hepatozoon sp. was observed in 32 % of the wildcats, while one individual was coinfected with C. europaeus and B. vulpes. Occurrence of H. felis was higher in adult wildcats. No spatial structure or correlation with body condition was observed for any of the parasites. Given the widespread presence of Cytauxzoon and other parasites in this and other wildcat populations, their impact on wildcat health, if any, is likely to be minimal. However, wildcats appear to serve as important maintenance hosts for these parasites.Gobierno de AragónUniversidad de Castilla La ManchaUniversidad de MurciaEuropean CommissionDepto. de Sanidad AnimalFac. de VeterinariaTRUEpu

SEM, EBSD, laser confocal microscopy and FE-SEM data from modern Glycymeris shell layers
No full textHere, we provide the dataset associated with the research article “Orientation patterns of aragonitic crossed-lamellar, fibrous prismatic and myostracal microstructures of modern Glycymeris shells” [1]. Based on several tools (SEM, EBSD, laser confocal microscopy and FE-SEM) we present original data relative to the microstructure and texture of aragonite crystallites in all Glycymeris shell layers (crossed-lamellar, complex crossed-lamellar, fibrous prismatic and pedal retractor and adductor myostraca) and address texture characteristics at the transition from one layer to the other, identifying similarities and differences among the different layers. Shells were cut transversely, obliquely and longitudinally in order to obtain different orientated sections of the outer and inner layer and of the myostraca. The identification of major microstructural elements was provided by detailed SEM and laser confocal microscopy images. Microstructure and texture characterization was based on EBSD measurements presented as band contrast images and as color-coded crystal orientation maps with corresponding pole figures. Crystal co-orientation was measured with the MUD value. Finally, the distribution of the organic matrix occluded within the outer crossed-lamellar layer was revealed using FE-SEM. These data, besides providing a modern unaltered Glycymeris reference to detect diagenetic alteration in fossil analogs used for paleoenvironmental reconstructions, are useful to better comprehend the mechanisms of bivalve shell formation
Tightly shut: flexible valve margins and microstructural asymmetry in pterioid bivalves
No full textAbstract: An organic-rich columnar prismatic outer shell layer, which extends far beyond the underlying nacre, has allowed pterioid bivalves (the pearl oysters and their allies) to develop flexible valve margins, allowing a tight hermetic seal when shut. In some taxa, the microstructural arrangement is known to be asymmetrically developed between the two valves. The asymmetry was surveyed across 29 taxa of pterioids (including representatives of known genera) confirming that it is typically the right valve which has a greater expanse of prism-only shell (and less nacre) and showing that this portion of the right valve has more organic content (more than twice the value in some instances) than the equivalent in the left. A more detailed investigation of prismatic material in Pteria penguin comparing the right and left valves revealed that the right valve flange has a higher density of smaller prisms, each with its organic envelope, and not a greater thickness of the organic envelopes themselves. The flange is also thinner on the right valve and shown here to be very flexible when wet. This allows it to bend against the rigid left valve when the shell is closed. Comparison of this structural asymmetry in the pterioids with five outgroup taxa in the Ostreidae and Pinnidae suggests that clades with the asymmetry have been freed from the constraints of a flattened valve morphology and to develop inequivalved forms
