HOW TO RESTORE SOIL FUNCTIONALITY IN DEGRADED AREAS OF VINEYARDS

In both conventional and organic vineyards, it is quite common to have areas characterized by problems in vine health, grape production and quality, often caused by improper land preparation before vine plantation and/or management. Causes for soil malfunctioning can include: reduced contribution of the soil fauna to the ecosystem services (i.e. nutrient cycles), poor organic matter content, imbalance of some element ratio, altered pH, water deficiency, soil compaction and/or scarce oxygenation. ReSolVe is a transnational and interdisciplinary 3-years research project of the within the FP7 ERA-Net CORE Organic Plus aimed at testing the effects of selected organic strategies for restoring optimal soil functionality in degraded areas within vineyard. The different restoring strategies implemented in each plot will be: i) compost produced on farm by manure pruning residue grass, ii) faba bean and barley green manure, iii) sowing and dry mulching with Trifolium squarrosum L. During two years of such treatments, the trend of the soil features and the grapevine status will be monitored in detail, to reveal the positive the soil features and the grapevine status will be monitored in detail, to reveal the positive and negative effects of such treatments

Rethinking Lyric Communities

From the circulation of poetic forms across different languages and traditions around the globe, through the envisioning of national and transnational discursive communities, to the use of poetry in contemporary episodes of political resistance and its dissemination on social media, lyric poetry seems to be a privileged site for an inquiry into community formation and its politics. Various theoretical approaches cast poetry in this peculiar role, from French and French-oriented political philosophy, (exemplified in the famous exchange between Maurice Blanchot and Jean-Luc Nancy begun in the 1980s), to the reevaluations — in reader-response criticism as well as in postcolonial and decolonial studies — of poetry’s roots in orality and performance. This workshop aims to bring the investigation of historical poetic communities into dialogue with recent developments in the theory of the lyric and in theories of community. While discussing a variety of poetic phenomena in modern European poetry that have been at the center of the critical debate — the poetics of the fragment, the unworking or désœuvrement of the work, the obscurity or polysemy of language, a change of aesthetic regime —, the workshop will also explore the lyric, in its longer history and transnational features, as a particular discursive mode that may offer alternative models of community formation. This symposium consists of three parts: an Oxford session at the Christ Church Research Centre, on 23 June 2022, a Berlin session at the ICI Berlin, on 5 July, and a poetry event, also on 5 July, at the ICI Berlin with Vahni Anthony Capildeo, Christian Hawkey, and Daniel Tiffany, who will read a selection of their poetry and offer their reflections on poetry, community and translation.Rethinking Lyric Communities, symposium, ICI Berlin, 5 July 2022 <https://doi.org/10.25620/e220705

MAPPING SOIL SPATIAL VARIABILITY AT HIGH DETAIL BY PROXIMAL SENSORS FOR A VINEYARD PLANNING

Planning new vineyard needs accurate information about soil features and their spatial variability. The use of soil proximal sensors, coupled by few detailed soil observations and analysis allows to obtain high detailed maps of soil variability at affordable costs. The work showed the methodology to interpolate the proximal sensors data and to delineate homogeneous area by clustering, corresponding to likely soil units. The description and analysis of one profile for each homogeneous area allowed to describe the soil features of each soil typological units and to produce useful thematic maps for vineyard planning

Pietro Aretino e Luciano di Samosata. Paradosso e parrhesia tra parola e immagine

Pietro Aretino constantly flaunts his originality and uniqueness as a writer. This essay seeks to show that, on the contrary, his authorial figure arises from a rewriting and a ‘refiguring’ of Lucian, especially as far as the centrality of paradox and of parrhesia are concerned. The present study reinterprets or adduces hitherto ignored evidence (consisting of both textual and iconographic materials, such as portraits, marche editoriali, and medals) in order to reconstruct some key aspects of Aretino’s relationship to Lucian, thus questioning the traditional idea of the writer’s unfamiliarity with the processes of imitatio of antiquity. Aretino’s approach to Lucian is investigated on three different levels, i.e. the level of intertextuality, of themes and genres, and of authorship. Firstly, the analysis inspects how Aretino’s Dialogo was influenced by a specific collection of vernacular translations of Lucian (I dilettevoli dialogi, 1525). Furthermore, the essay unveils the close relationship between Dialogo and Lucian’s De parasito as a model of paradoxical eulogy, thereby showing that Aretino’s text not only reverses the structures of relevant literary genres (e.g. the Platonic dialogue) but also originates from a ‘positive’ imitation of other generic templates (such as the Lucianistic paradoxical encomium). Finally, new findings about the sources of Aretino’s motto veritas odium parit and of its iconography shed light on the way Aretino fashions himself as a parrhesiastes by reproducing and transforming – and therefore imitating – Lucian’s figura auctoris

Derecho canónico interdisciplinar. Ideas para una renovación epistemológica

The current situation of canon law studies evinces division not only between theology and canon law, but also between canon law, civil law and ethics. What is missing today is the common ground between canon and civil law, which enabled fruitful collaboration in times past. This article emphasizes the need for a new dialogue between canonical and secular sciences and explores models, requirements, benefits and purposes for the interrelationships between theology, canon law and the social sciences.La situación actual de la ciencia canónica pone en evidencia la separación existente no solo entre la teología y el derecho canónico, sino entre este último, el derecho secular y la ética. Ha venido a faltar esa base común entre el derecho canónico y el derecho secular que, durante tantos siglos, había garantizado una fecunda colaboración entre ellos. El artículo se propone subrayar la necesidad de que la ciencia canónica se abra al diálogo con las ciencias seculares. A este fin, examina los modelos, las condiciones, las ventajas y los objetivos de las relaciones multidisciplinares entre la teología, el derecho canónico y las ciencias sociales

Localization of apolipoprotein A-I epitopes involved in the activation of lecithin: Cholesterol acyltransferase

Eight murine monoclonal antibodies (Mab) to apolipoprotein A-I were characterized for their epitopes and for their ability to interfere with lecithin:cholesterol acyltransferase (LCAT) activation mediated by apo apoA-I using a synthetic substrate. Using overlapping synthetic peptides we have identified six continuous epitopes that span amino acids 1-10 (Mab A-I-19), 96-101 (Mab A-I-15), 133-141 (Mab A-I-5), 140-145 (Mab A-I-9), 144-148 (Mab A-I-8), and 167-174 (Mab A-I-57). Furthermore, antibodies A-I-11 and A-I-16 recognized discontinuous epitopes, namely amino acids 124-128 and 144-148. When antibodies were tested for their ability to inhibit LCAT activation, an inhibitory effect was observed with those whose epitopes covered the area of apoA-I encompassing amino acids 96-174. From these data we conclude that several areas of apoA-I spanning the middle region of the apolipoprotein act in concert to stimulate LCAT activity, possibly by cooperative interaction with the enzyme

Avaliação da ameaça de erosão hídrica na ilha da Madeira - Portugal

Na estimativa da erosão hídrica na ilha da Madeira aplicou-se a Equação de Wischmeier. Recorreu-se a relações para estimar a erosividade (R); foi adequado o Índice Modificado de Fournier e relação IMF/R. cartografada a erosividade os restantes parâmetros resultaram da metodologia. IMF varia entre 81.0–465.0 mm. A equação R = 1.365 IMF1.408 estima a erosividade anual precipitação, com dados de Funchal-Observatório, sul de Portugal e valores da literatura, obtendo-se R ≈ 2 964 MJ mm h−1 ha−1 ano−1, variando entre 660- 8515. Erosão média é 28 t ha−1 ano−1, excedendo 100 em >4.9% da área. A ameaça de erosão adveio da divisão do volume de solo dos horizontes mobilizáveis, pela erosão anual. O resultado -número de anos- que ocorre a perda do solo de cobertura. Apesar do tempo para esgotamento do solo, ser >20 000 anos, a ameaça de erosão, alta e muito alta, é relevante. Estas ameaças (depleção <100 anos) ocorrem em 263 km2 (35.6%); na ameaça muito alta (depleção em <10 anos) a área é ≈40 km2 (5.4%). Encostas com declives muito elevados estão associadas a ameaças altas (ou muito altas). Efetuouse a análise da precipitação 20 de Fevereiro, obtendo-se um período de retorno superior a 100 anos.info:eu-repo/semantics/publishedVersio

Restoring soil functionality in degraded areas within vineyards by organic treatments: the experimental layout of the RESOLVE Core-organic+ project

Degraded areas are frequent in vineyards, even if managed by organic farming, mainly caused by soil truncation, soil erosion, or salts enrichment. Recovering strategies implemented in 19 degraded vineyards in 5 countries within the RESOLVE project concerned: (i) composted organic amendments, or seeding of cover crops (including legumes) for (ii) green manure or (iii) dry mulch. The relationships between vineyard management and pedo-climatic conditions are useful to better understand other contributions dealing with RESOLVE project reported in the present special issue. The results suggested that the nature of degradation requires optimum seedbed preparation to grow green manure crops. Whereas dry mulching plants needs less tillage operations (neither incorporation nor sowing, if self-reseeding plants), helping the recovery of soil functionality. The potential soil erosion by water was esteemed for the 38 plots, confirming that is a common agent of land degradation in vineyards
