Further 4 males and 7 females from Calabria (CS, Monte Cocuzzo; CS, Cava di Melis; CS, Cosenza/Donnici; VV, Lago Angitola; all in ZSM) in habitus corresponding to the characteristic features of H. mediterranea but excluded from the type series because of the distance from the type locality and the missing confirmation by DNA barcodes. Description. External characters and pregenital abdomen (diagnostic characters underlined) (Figures 2, 7): Wingspan male 31 mm (n=4), female 37–41 mm (n=4). Wings light green, medial lines white. Medial line curved before costa, basal part moves away from costa (not parallel with costa). Postmedial line rather straight, only weakly curved, barely angled before it reaches costa near apex and evenly curved outwards on inner margin. Medial area concolorous with rest of wing. Terminal line and fringes concolorous with wings, forewing apex dark red. Hindwing postmedial line distinct, curved. Discal spots absent. Wings below as above, but paler. Frons redbrown, thorax and abdomen concolorous with wings. Area between antennae (vertex) white. Antennae white dorsally, male antennae bipectinate, female antennae fasciculate. Hindleg tibia of both sexes with 2+2 spurs. Tympanal organs medium-sized. Sternites and tergites 3–8 of both sexes undifferentiated. Male genitalia (Figure 11): Generally as in H. fasciaria (Linnaeus) and H. pinicolaria (Bellier). Aedeagus with additional arm, apex not expanded in H. mediterranea (apex expanded in H. compararia). Base of vesica with straight row of microcornuti in H. mediterranea (vesica with angled row of microcornuti, reaching aedeagus apex in H. compararia). Uncus relatively narrower before wide apex in H. mediterranea (uncus relatively wider before wide apex in H. fasciaria and H. pinicolaria, but the differences are not clear-cut). Female genitalia (Figure 15): Generally as in H. fasciaria and H. pinicolaria (Bellier), but with following quantitative difference: signum large in H. mediterranea (signum absent or minute in H. fasciaria, H. pinicolaria and in H. compararia). Genitalia are large in H. mediterranea (genitalia considerably smaller in H. compararia). Shape and size of the lamella antevaginalis, and width and length of the posterior part of the corpus bursae are variable and should be treated with caution. Distribution (Figure 20). Type specimens originate from Sicily (Italy, DNA barcoded), one specimen from Calabria (Italy, taken out of a longer series and DNA barcoded) and three specimens from Molise (Italy, DNA barcoded). One further specimen has been reported from the island of Marettimo, West of Sicily (L. Dapporto, pers. comm., not DNA barcoded). Outside this the distribution area needs verification. Some specimens from Greece, for instance from Mount Parnassos, Karpenision and Lesvos, are externally similar, but the female signum is small, thus not agreeing with the Italian material. DNA barcodes are not available, so far, for Greek populations. Phenology. Bivoltine: In Sicily it flies from late May (rarely early May) to early July and from late August to late October (Flamigni et al. in press). Biology. The species has been reared (G. Fiumi and D. Righini) from the Etna Mountain, Sicily. Female laid eggs on May 1 st (Figure 22), the caterpillars fed on the needles of Pinus sylvestris and Picea abies (Figure 23), the first pupa was observed on June 26 th (Figure 24) and the first adult (Figure 25) emerged on 11 July. Pinus sylvestris and Picea abies are not present in Sicily; in the collecting localities Pinus laricio and P. halepensis are common. Habitat (Figure 21). In pine forests and places with more scattered pine trees. Altitude range from sea level to 1780 m (Flamigni et al. in press). Similar species. All four species in the Palaearctic Hylaea fasciaria species group are similar. The diagnostic, external characters shown in the Figures 6–9 are somewhat tentative and should not be used in isolation, but should be combined with other information including biology, collecting locality, male and female genitalia and DNA barcodes. An overview of diagnostic morphological features is given in Table 1. The taxon squalidaria (as judged from the original figure) differs in the straight forewing medial line, not curved at costa; forewing medial and postmedial lines at large distance, thus the medial area very broad; hindwing postmedial line strongly curved, parallel to termen. Genetic data. Genetically homogeneous in Calabria, Molise and Sicily (n=8), mean intraspecific variation 0.19%, maximum variation 0.46%. Nearest species: Hylaea fasciaria (minimum pairwise distance 3.3%). See Figure 26. Variation. Little variation in habitus observed, so far. Forewing postmedial line is straight or weakly curved outwards on inner margin. The specimens from Calabria (Italy) often have the forewing postmedial line clearly angled before it reaches costa. Only light green specimens are known. Etymology. The species name mediterranea refers to the Mediterranean area, where the species occurs.Published as part of Sihvonen, Pasi, Skou, Peder, Flamigni, Claudio, Fiumi, Gabriele & Hausmann, Axel, 2014, Revision of the Hylaea fasciaria (Linnaeus, 1758) species group in the western Palaearctic (Lepidoptera: Geometridae, Ennominae), pp. 469-486 in Zootaxa 3768 (4) on pages 478-479, DOI: 10.11646/zootaxa.3768.4.5, http://zenodo.org/record/490965

“Dialogue between Translators and Authors. The Example of Claudio Magris”
No full textThe paper focuses on the forms of cooperation between authors and their translator(s) in all cases in which the two operate simultaneously. This issue is explored on the example of the Trieste-born author Claudio Magris, who cultivates a very close relationship with most of his translators.
Writing and translation have been coexisting in this author throughout his career and have resulted in the heightened sensitivity of Magris the author with regards to translation, as the first part of the analysis shows. The second part describes the dialogue between Magris and the translators of his works, and ends with the more general question of the significance and role of such a form of exchange
Consideraciones sobre la poética de Claudio Rodríguez
No full textThe purpose of this paper is to study the poetics of Claudio Rodríguez, delimiting its components and trying to clarify them and to present them as a whole. The author left some pages written on his conception of poetry that encourage reflection and, in some cases, interpretation. So with his conception of poetry as a gift and inebriation, as an alliance and condemnation or celebration (giving title to his collections of poems), or with notions such as «participation», «living contemplation», «living expression » or «personal rhythm» that make up his way of understanding the poetic process.El propósito de este artículo es estudiar la poética de Claudio Rodríguez, deslindando sus componentes y tratando de clarificarlos y presentarlos en su conjunto. El autor dejó escritas algunas páginas sobre su concepción de la poesía que animan a la reflexión y, en algunos casos, a la interpretación. Así sucede con su concepción de la poesía como un don y una ebriedad, como alianza y condena o como celebración (que dan título a sus poemarios), o con nociones como las de «participación», «contemplación viva», «expresión viva» o «ritmo personal», que configuran su forma de entender el proceso poético
Photoinduced electron transfer across oligo-p-phenylene bridges. Distance and conformational effects in Ru(II)-Rh(III) dyads
No full textA series of rodlike ruthenium(II)-rhodium(III) polypyridine dyads based on modular oligo-p-phenylene bridges, of the general formula [(Me 2phen)2Ru-bpy-(ph)n-bpy-Rh(Me 2bpy)]5+ (Me2phen = 4,7-dimethyl-1,10- phenanthroline; bpy -2,2′-bipyridine; ph = 1,4-phenylene; n = 1-3), have been synthesized and their photophysical properties investigated. The dyad [(Me2bpy)2Ru-bpy-(ph)3′-bpy-Rh(Me 2bpy)]5+ with the central phenylene unit bearing two hexyl chains has also been studied. The metal-to-metal distance reaches 24 Å for the longest (n = 3) spacer in the series. For all of the dyads in a room-temperature CH3CN solution, quenching of the typical metal-to-ligand charge-transfer luminescence of the Ru-based chromophoric unit is observed, indicating that an efficient intramolecular photoinduced electron transfer from the excited Ru moiety to the Rh-based unit takes place. The rate constants for the electron-transfer process have been determined by time-resolved emission and absorption spectroscopy in the nanosecond and picosecond time scale. An exponential dependence of experimental transfer rates on the bridge length is observed, consistent with a superexchange mechanism. An attenuation factor β of 0.65 Å is determined, in line with the behavior of other systems containing oligo-p-phenylene spacers. Interestingly, for n = 3, the presence/ absence of hexyl substituents in the central p-phenylene ring causes a 10-fold difference in the rates between otherwise identical dyads. This comparison highlights the importance of the twist angle between adjacent spacers on the overall through-bond donor-acceptor coupling
Effect of superoxide generation on rat heart mitochondrial pyruvate utilization
No full textPrevious research has shown that heart mitochondria are able to produce reactive species of oxygen such as superoxide radicals, hydrogen peroxide and hydroxyl radicals [10, 11]. When these compounds are formed beyond a certain level they are not completely removed by the enzymatic and metabolic processes which neutralize their toxicity, and as a result they are able to produce structural and functional damages that impair mitochondrial function [5, 10]. In order to study the molecular mechanism/s by which the oxygen radicals may function as mediators of cellular injury a flow of these radicals by chemical, enzymatic or photochemical methods has been generated in vitro in the presence of cellular preparations. For example, the exposure of isolated subcellular particles to the enzymatic flow of oxygen radicals produced by the reaction of xanthine oxidase upon xanthine reduced both calcium uptake velocity and Ca2+-ATPase activity in sarcoplasmic reticulum [7], while it reduced Ca2+-stimulated ATPase activity in myofibrillar preparations [4]. In addition, incubation with the xanthine oxidase reaction produced an impairment of the respiratory functions associated with an increased lipid peroxidation in the isolated mitochondria [5, 10]. These negative effects were augmented in alpha-tocopherol-deficient mitochondria [3], but were opposed by the exogenous addition of superoxide dismutase [10]. This report shows that the superoxide radicals generated by the xanthine oxidase reaction reduced rat heart mitochondrial respiration induced by pyruvate. This negative effect was partially prevented by superoxide dismutase and catalase and by thiol protecting agents. Moreover, the generation of free radicals caused a significant reduction in the rate of (1-14C) -pyruvate decarboxylation, while it did not change the transport of pyruvate into mitochondria
