N. Tasin y la España de la Edad de Plata
No full textTesis inédita de la Universidad Complutense de Madrid, Facultad de Filología, leída el 25-11-2019Bajo el seudónimo ―N. Tasin‖, Naum Yakóvlevich Kagan (1873-1941) escribió un abundante número de artículos de periódicos, relatos, novelas, libros políticos y traducciones a lo largo de su vida. Tasin llevó una vida nómada debido a sus actividades políticas, que lo convirtieron en exiliado tanto del régimen zarista como de los bolcheviques, manteniéndose fiel a los principios del socialismo democrático. Tasin llegó a España expulsado de Francia en 1918 y permaneció en nuestro país hasta 1921, año en que la presión policial y el encargo de una corresponsalía de El Imparcial lo llevaron a Berlín. Durante esos tres años, el autor se concentró sobre todo en las traducciones de literatura rusa, que en España se habían hecho tradicionalmente a partir de versiones francesas de los originales rusos. La crítica ha venido sosteniendo tradicionalmente que con Tasin empezaron en España las traducciones directas del ruso...Under the pseudonym "N. Tasin‖, Naum Yakóvlevich Kagan (1873-1941) wrote throughout his life an important amount of newspaper articles, stories, novels, political books and translations. Tasin led a nomadic life due to his political activities, which made him an exile from both the Tsarist regime and the Bolsheviks, staying true to the principles of democratic socialism. Tasin arrived in Spain expelled from France in 1918 and remained in our country until 1921, when police pressure and the commission as a correspondent from El Imparcial took him to Berlin. During those three years, the author focused mainly on translations of Russian literature which in Spain had traditionally been made from French versions. Criticism has maintained that his where the first direct translations fronm Russian into Spanish. However, the study of different documents and the analysis of the translations themselves show that this was not always the case and that the author had different Spanish-language collaborators...Fac. de FilologíaTRUEunpu
Structural and electronic properties of TaSin (n=1-13) clusters: A relativistic density functional investigation
No full textThe TaSin (n=1-13) clusters with doublet, quartet, and sextet spin configurations have been systematically investigated by a relativistic density functional theory with the generalized gradient approximation available in Amsterdam density functional program. The total bonding energies, equilibrium geometries, Mulliken populations as well as Hirshfeld charges of TaSin (n=1-13) clusters are calculated and presented. The emphasis on the stabilities and electronic properties is discussed. The most stable structures of the small TaSin (n=1-6) clusters and the evolutional rule of low-lying geometries of the larger TaSin (n=7-13) clusters are obtained. Theoretical results indicate that the most stable structure of TaSin (n=1-6) clusters keeps the similar framework as the most stable structure of Sin+1 clusters except for TaSi3 cluster. The Ta atom in the lowest-energy TaSin (n=1-13) isomers occupies a gradual sinking site, and the site moves from convex, to flatness, and to concave with the number of Si atom varying from 1 to 13. When n=12, the Ta atom in TaSi12 cluster completely falls into the center of the Si frame, and a cagelike TaSi12 geometry is formed. Meanwhile, the net Mulliken and Hirsheld populations of the Ta atom in the TaSin (n=1-13) clusters vary from positive to negative, manifesting that the charges in TaSin (ngreater than or equal to12) clusters transfer from Si atoms to Ta atom. Additionally, the contribution of Si-Si and Si-Ta interactions to the stability of TaSin clusters is briefly discussed. Furthermore, the investigations on atomic averaged binding energies and fragmentation energies show that the TaSin (n=2,3,5,7,10,11,12) clusters have enhanced stabilities. Compared with pure silicon clusters, a universal narrowing of highest occupied molecular orbital-lowest unoccupied molecular orbital gap in TaSin clusters is found.

Chern Numbers of Uniruled Threefolds
No full textIn this paper we show that the Chern numbers of a smooth Mori fibre space in dimension three are bounded in terms of the underlying topological manifold. We also generalise a theorem of Cascini and the second named author on the boundedness of Chern numbers of certain threefolds to the case of negative Kodaira dimension
Aplasia cutis congenita in surviving co-twins: four unrelated cases
No full textFour unrelated patients born from twin pregnancies and showing extracranial aplasia cutis congenita are reported. All the patients lost their co-twins during the first half of the pregnancy. Two of the patients had the characteristic truncal and symmetrical type of aplasia cutis associated with fetus papyraceus and placental abnormalities. The presence of multiple hepatic hematomas in one of them gives further credit to a "vascular disruption" as the possible pathogenetic mechanism of the disorder. The two other patients were born with symmetrical aplasia cutis at the extensory aspects of both knees, which presumably represents a milder expression of the former defect. Thus the so-called aplasia cutis with fetus papyraceus shows heterogeneity in localization, extension, presence of extracutaneous abnormalities, and possible association with fetus papyraceus at birth. To include all the patients affected by this peculiar type of aplasia cutis congenita, the designation of aplasia cutis with extracranial symmetrical involvement is proposed

No full textEcoOrchard – collecting existing knowledge and generating new knowledge on functional biodiversity of organic orchards
No full textOrganic fruit growers often suffer economic losses due to insect damages. The available natural pest control products are not always effective; and most important: many organic fruit growers would prefer not to use any pesticide at all. EcoOrchard, a CORE Organic Plus project (2015-18) aims to collect existing knowledge and generate new knowledge in order to use Functional AgroBiodiversity (FAB) successfully in orchards. This includes experimental trials in seven countries on the potential of inter-row flower strips for control of key pests and natural enemy augmentation, the establishment of the EBIO-Network as a European-wide network of stakeholders for collecting, sharing and improving scientific and practical knowledge and experience in FAB management, the development and testing of simple FAB assessment tools for use on-farm by growers and advisors, and finally, using a participatory approach to learn about potential constraints that may hamper the adoption of innovative tools and how to solve these constraints by iterative reevaluation

Management trade-offs on ecosystem services in apple orchards across Europe : Direct and indirect effects of organic production
No full textApple is considered the most important fruit crop in temperate areas and profitable production depends on multiple ecosystem services, including the reduction of pest damage and the provision of sufficient pollination levels. Management approaches present an inherent trade-off as each affects species differently. We quantified the direct and indirect effects of management (organic vs. integrated pest management, IPM) on species richness, ecosystem services, and fruit production in 85 apple orchards in three European countries. We also quantified how habit composition influenced these effects at three spatial scales: within orchards, adjacent to orchards, and in the surrounding landscape. Organic management resulted in 48% lower yield than IPM, and also that the variation between orchards was large with some organic orchards having a higher yield than the average yield of IPM orchards. The lower yield in organic orchards resulted directly from management practices, and from higher pest damage in organic orchards. These negative yield effects were partly offset by indirect positive effects from more natural enemies and higher flower visitation rates in organic orchards. Two factors other than management affected species richness and ecosystem services. Higher cover of flowering plants within and adjacent to the apple trees increased flower visitation rates by pollinating insects and a higher cover of apple orchards in the landscape decreased species richness of beneficial arthropods. The species richness of beneficial arthropods in orchards was uncorrelated with fruit production, suggesting that diversity can be increased without large yield loss. At the same time, organic orchards had 38% higher species richness than IPM orchards, an effect that is likely due to differences in pest management. Synthesis and applications. Our results indicate that organic management is more efficient than integrated pest management in developing environmentally friendly apple orchards with higher species richness. We also demonstrate that there is no inherent trade-off between species richness and yield. Development of more environmentally friendly means for pest control, which do not negatively affect pollination services, needs to be a priority for sustainable apple production
