The role of dominant tree cover and silvicultural practices on the postfire recovery of Mediterranean afforestations
2018
Fire is one of the major disturbance factors in Mediterranean-type ecosystems, where since long time man has deeply modified the natural fire regime. To know how woody species recover after fire is of prominent importance for understanding vegetation dynamics, as well as for the management of Mediterranean plantations, especially where broadleaved and coniferous trees coexist. Our research was carried out at Monte Petroso (Sicily), within an historical afforestation intervention in the Mediterranean basin. We assessed the post-fire response of mixed oaks and oak-pine afforestations within six experimental plots (two plots per homogeneous sector) differing in dominant tree species (Quercus i…
Effects of Scientific Information Format on the Comprehension Self-Monitoring Processes: Question Generation
2013
RESUMEN: Formular preguntas es una de las acciones asociadas con procesos metacognitivos de regulación durante tareas de comprensión: los sujetos pueden generar preguntas destinadas a obtener información para salvar obstáculos de comprensión. Se realizaron dos experimentos para estimular, clasificar y analizar las preguntas de los estudiantes en tres condiciones diferentes: leer sobre el funcionamiento de dispositivos científicos experimentales, observarlos en un DVD o manipularlos en el Laboratorio. Las preguntas fueron clasificadas usando una taxonomía sencilla. Teniendo en cuenta los principios multimedia de aprendizaje, las ventajas de imágenes realistas animadas para el aprendizaje de …
The Embryo Development in Quranic Verses
2016
The aim of this paper is to answer two questions: is there a section in the Quran that describes the human embryo development? Second, if such a case existed, could it be compared to the Greek theories of generation? The answer to both questions is affirmative. In the first part of this paper, we discuss some Quranic verses talking about the embryo development. We also outline how the terminology (nufah, alaqah, mughah) used for expressing the embryo development in these verses involves complex translation challenges. In the second part, we compare the Quranic verses to two Greek theories of generation. Finally, we highlight a little-known aspect of the Quranic text worthy of study.
Progettare città nel tempo della metamorfosi
2013
Metamorfosi è una potente parola-guida della contemporaneità. E’ un impegno di cui numerosi segni ci facevano intravedere la necessità durante gli anni propulsivi della globalizzazione e molteplici indizi tracciavano la strada da percorrere. Ma, anestetizzati dalle aporie dello sviluppo, li abbiamo ignorati, emarginandoli nella ecosofia o reagendo in modo impulsivo con seducenti inni alla decrescita felice. Oggi invece gli anni recessivi di una crisi che non è una semplice stagione di attraversamento ci chiedono la responsabilità di un mutamento di paradigma che conduca alla metamorfosi ecologica, culturale, economica, sociale e politica. Ma il mutamento sarà soprattutto urbano, perché vivi…
Rapid shifting of a deep magmatic source at Fagradalsfjall volcano, Iceland
2022
AbstractRecent Icelandic rifting events have illuminated the roles of centralized crustal magma reservoirs and lateral magma transport1–4, important characteristics of mid-ocean ridge magmatism1,5. A consequence of such shallow crustal processing of magmas4,5 is the overprinting of signatures that trace the origin, evolution and transport of melts in the uppermost mantle and lowermost crust6,7. Here we present unique insights into processes occurring in this zone from integrated petrologic and geochemical studies of the 2021 Fagradalsfjall eruption on the Reykjanes Peninsula in Iceland. Geochemical analyses of basalts erupted during the first 50 days of the eruption, combined with associate…
FEDRO: a software tool for the automatic discovery of candidate ORFs in plants with c →u RNA editing
2019
RNA editing is an important mechanism for gene expression in plants organelles. It alters the direct transfer of genetic information from DNA to proteins, due to the introduction of differences between RNAs and the corresponding coding DNA sequences. Software tools successful for the search of genes in other organisms not always are able to correctly perform this task in plants organellar genomes. Moreover, the available software tools predicting RNA editing events utilise algorithms that do not account for events which may generate a novel start codon. We present Fedro, a Java software tool implementing a novel strategy to generate candidate Open Reading Frames (ORFs) resulting from Cytidi…
Large-scale analysis of SARS-CoV-2 spike-glycoprotein mutants demonstrates the need for continuous screening of virus isolates
2021
Due to the widespread of the COVID-19 pandemic, the SARS-CoV-2 genome is evolving in diverse human populations. Several studies already reported different strains and an increase in the mutation rate. Particularly, mutations in SARS-CoV-2 spike-glycoprotein are of great interest as it mediates infection in human and recently approved mRNA vaccines are designed to induce immune responses against it. We analyzed 1,036,030 SARS-CoV-2 genome assemblies and 30,806 NGS datasets from GISAID and European Nucleotide Archive (ENA) focusing on non-synonymous mutations in the spike protein. Only around 2.5% of the samples contained the wild-type spike protein with no variation from the reference. Among…
Two distinct extracellular RNA signatures released by a single cell type identified by microarray and next-generation sequencing
2016
ABSTRACT Cells secrete extracellular RNA (exRNA) to their surrounding environment and exRNA has been found in many body fluids such as blood, breast milk and cerebrospinal fluid. However, there are conflicting results regarding the nature of exRNA. Here, we have separated 2 distinct exRNA profiles released by mast cells, here termed high-density (HD) and low-density (LD) exRNA. The exRNA in both fractions was characterized by microarray and next-generation sequencing. Both exRNA fractions contained mRNA and miRNA, and the mRNAs in the LD exRNA correlated closely with the cellular mRNA, whereas the HD mRNA did not. Furthermore, the HD exRNA was enriched in lincRNA, antisense RNA, vault RNA, …
Il progetto “Oltre l’orizzonte: contro-narrazioni dai margini al centro”
2020
Il contributo descrive il progetto europeo OLTRE, acronimo di “Oltre l’orizzonte: Contro-narrazioni dai margini al centro”, è un progetto cofinanziato dalla Commissione europea, in particolare dal DG Affari Interni (Fondo per la Sicurezza Interna - Programma per l’Empowerment della Società Civile). OLTRE nasce con la finalità precipua di contribuire alla prevenzione dei fenomeni di radicalizzazione islamica sul territorio italiano, principalmente attraverso una campagna di comunicazione online. Per prevenire la radicalizzazione è necessario ridurre la vulnerabilità dei soggetti ritenuti “a rischio”, nel nostro caso specifico i giovani italiani con background migratorio di fede musulmana.
Second-Generation Muslim Youth Between Perception and Change: A Case Study on the Prevention of Radicalization
2020
The following article presents the results of a research-action and an online communication campaign on the prevention of radicalization of second-generation young Italian Muslims as a part of a project called “Oltre” (the Italian acronym means “Beyond”) financed by European Union. After a short presentation of the four steps of the prevention communication model PKIC, a deepening on the radicalization factors, and a focus on the research-action methodology, the results of the research on some fundamental issues like the relationship with family and the relation with media and social media of the young interviewees, are shown. Finally, in the last part of the article, the interventions carr…
