"Role of Arbuscular Mycorrhizal Fungi in Nutrient Uptake and Growth of Durum Wheat"

Soil microbiome is involved at different levels in the food web, in bio-geochemical nutrient cycles and in several interactions with plants. Based on its key role in the agro-ecosystem processes, the soil microbiome has been identified as one of the principal factors in an agriculture addressed to the ecological intensification. Among the several relationships established between plants and soil microorganisms, arbuscular mycorrhizal (AM) symbiosis is the most widespread. Two out of three of all plant taxa (among others the main crops) are involved in the AM symbiosis which takes place between the plant root system and arbuscular mycorrhizal fungi (AMF), a monophyletic group of fungi belong…

Creencias religiosas <i>versus</i> gestión del patrimonio arqueológico: el Caso del cementerio Judío de Valencia

2001

Archaeological heritage ownership is a controversial subject under the influence of both ethnic and religious claims. In 1996, a group of Jewish communities finally were able to interrupt the archaeological excavation under way at the medieval Jewish cemetery of Valencia. In this manner they did not allow the anthropological analysis of human remains recovered at the site that were reburied at the Jewish cemetery of Barcelona. Both administrations, local and regional, prioritized religious claims of the communities involved with respect to the archaeological heritage. As a consequence of a complaint filed by a group of citizens, the Sindic of Greuges of the Valencian Community (regional omb…

1200 years of decadal-scale variability of Mediterranean vegetation and climate at Pantelleria Island, Italy.

2013

A new sedimentary sequence from Lago di Venere on Pantelleria Island, located in the Strait of Sicily between Tunisia and Sicily was recovered. The lake is located in the coastal infra-Mediterranean vegetation belt at 2 m a.s.l. Pollen, charcoal and sedimentological analyses are used to explore linkages among vegetation, fire and climate at a decadal scale over the past 1200 years. A dry period from ad 800 to 1000 that corresponds to the 'Medieval Warm Period' (WMP) is inferred from sedimentological analysis. The high content of carbonate recorded in this period suggests a dry phase, when the ratio of evaporation/precipitation was high. During this period the island was dominated by thermop…

Sant’Eligio degli Argentieri: dialoghi sul destino di un rudere

2021

In meetings between the silversmiths Pietro Accardi and Silvano Barraja with Luciana Macaluso, professor of architectural design, the events that reduced the church of San Eligio in Palermo to ruins were retraced and a different destiny for the monument has been envisioned. The church was built by the silversmith confraternity in 1650 and dedicated to their patron saint, a silversmith of French origins. The earthquake of 15 January 1940 damaged the structure and, three years later, a bomb destroyed the roof of the main body. During the 1950s, the shops in the square of the same name multiplied to the point of occupying part of the church. The subsequent decline in craft activities and the g…

Human Sociability in Antonio Montecatini's (1537–99) Commentary on Aristotle's Politics

2021

The present article delves into the history of political philosophy by discussing human sociability in Antonio Montecatini's (1537–99) commentary on Aristotle's Politics. The focus is on a philosophical analysis of three interrelated ideas that Montecatini discusses: (1) Aristotle's dictum that human beings are political animals by nature; (2) naturalness of the household; and (3) the nature and origin of political communities. Montecatini's views are briefly related to those of John Case (ca. 1546–1600), and they are also contextualized within the late medieval commentary tradition on the Politics, but the main aim is to clarify Montecatini's philosophical position and examine the ways in …

A methodological protocol for Annex I Habitats monitoring: the contribution of Vegetation science.

2016

The methodological foundations of the recently published Manual for Annex I Habitats monitoring in Italy, edited by the Italian Institute for Environmental Protection and Research (ISPRA) with the scientific support of the Italian Society for Vegetation Science (SISV), are here presented, discussed and related to the most consolidated and acknowledged scientific advances in the field of Vegetation science. The proposed methodologies aim at offering simple, yet effective, protocols and procedures towards a harmonized data collection, by way of standardized and shared technical tools, resulting in comparable evaluations of the conservation status of Annex I Habitats. The methodological framew…

Towards more relevance-oriented data mining research

2008

Data mining (DM) research has successfully developed advanced DM techniques and algorithms over the last few decades, and many organisations have great expectations to take more benefit of their data warehouses in decision making. Currently, the strong focus of most DM-researchers is still only on technology-oriented topics. Commonly the DM research has several stakeholders, the major of which can be divided into internal and external ones each having their own point of view, and which are at least partly conflicting. The most important internal groups of stakeholders are the DM research community and academics in other disciplines. The most important external stakeholder groups are manager…

Analyzing the Correlation of Classical and Community-aware Centrality Measures in Complex Networks

2021

International audience; Identifying influential nodes in social networks is a fundamental issue. Indeed, it has many applications, such as inhibiting epidemic spreading, accelerating information diffusion, preventing terrorist attacks, and much more. Classically, centrality measures quantify the node's importance based on various topological properties of the network, such as Degree and Betweenness. Nonetheless, these measures are agnostic of the community structure, although it is a ubiquitous characteristic encountered in many real-world networks. To overcome this drawback, there is a growing trend to design so-called community-aware centrality measures. Although several works investigate…

Implementation of the chemistry module MECCA (v2.5) in the modal aerosol version of the Community Atmosphere Model component (v3.6.33) of the Communi…

2013

Abstract. A coupled atmospheric chemistry and climate system model was developed using the modal aerosol version of the National Center for Atmospheric Research Community Atmosphere Model (modal-CAM; v3.6.33) and the Max Planck Institute for Chemistry's Module Efficiently Calculating the Chemistry of the Atmosphere (MECCA; v2.5) to provide enhanced resolution of multiphase processes, particularly those involving inorganic halogens, and associated impacts on atmospheric composition and climate. Three Rosenbrock solvers (Ros-2, Ros-3, RODAS-3) were tested in conjunction with the basic load-balancing options available to modal-CAM (1) to establish an optimal configuration of the implicitly-sol…

Temporal variability of airborne bacterial community structure in an urban area

2006

International audience; Temporal airborne bacterial genetic community structure and meteorological factors were analysed above an urban area in the northwest of France from December 2003 to April 2004 with a sampling strategy considering different time intervals (from an hour to a month). Principal component analysis (PCA) of B-ARISA (Bacterial-Automated Ribosomal Intergenic Spacer Analysis) profiles revealed a hierarchy in the temporal variability of bacterial community: daily<weekly<seasonal. Co-inertia analysis between B-ARISA data and meteorological factors demonstrated the correlation between the seasonal variability in the bacterial community and climatic conditions such as temperatur…
