Importazione massale di dati in Wikiplantbase: l'esperienza con Wikiplantbase #Sicilia
2019
Il progetto Wikiplantbase è stato avviato nel 2013 al fine di offrire un sistema dove caricare record floristici georeferenziati, liberamente accessibili via internet. Sino ad allora, infatti, esistevano un gran numero di banche dati online sulla nomenclatura, tassonomia, erbari, specie aliene, vegetazione, numeri cromosomici e sequenze di DNA, ma non vi era facile accesso ai dati floristici a grande dettaglio geografico. I record floristici costituiscono i dati primari sulla biodiversità utili per qualsiasi ricerca di biologia vegetale. Al fine di aumentare i dati sulla Sicilia disponibili in Wikiplantbase, si sono elaborati e standardizzati alcuni dei dati liberamente accessibili dal sito…
Agronomical evaluation of Sicilian biotypes of Lavandula stoechas L. spp. stoechas and analysis of the essential oils
2015
The aim of this study was to characterize wild lavender, which was collected in three different areas of Sicily (Italy),according to agronomic and chemical evaluation. The collection sites were located in Pantelleria island, Partinico (a warm sub-area of Lauretum) and Castelbuono (a middle sub-area of Lauretum). All the populations were identified as Lavandula stoechas L. ssp. stoechas. Essential oils were extracted by hydrodistillation and analyzed by gas chromatography– flame ionization detector (GC–FID) and GC–mass spectrometry (GC–MS). GC–FID and GC–MS analyses permitted the identification of 101 components from the essential oils. We analyzed only the flowers and leaves of L. stoechas …
Study of quantitative and qualitative variations in essential oils of Sicilian oregano biotypes
2015
Essential oil (EO) was extracted using hydrodistillation from samples of Origanum vulgare subspecies hirtum (Link) Ietswaart, gathered from the wild in various parts of Sicily, Italy; GC-FID and GC-MS analyses were subsequently performed. The aim of the study was to analyze the relationship between essential oil yields and the geographical distribution of oregano wild populations based on variations in environmental factors as collection sites. Moreover, the purpose was to group Origanum vulgare subspecies hirtum biotypes according to the chemical composition of the EO. The seven principal components in the EO was thymol (24.0–54.4%), γ-terpinene (9.8–30.5%), ρ-cymene (5.2–18.7%), α-terpine…
Quando Gilgameš taglia i “cedri”. Gli alberi nell’immaginario mitologico mesopotamico
2021
In the Sumerian and Akkadian mythological literature, the ruler of the city of Uruk, Gilgameš, uproots and/or cuts down trees on several occasions: the ḫalub-tree (mahaleb cherry) linked to the goddess Inanna and the eren (juniper)/erēnu (cedar) trees of the Forest guarded by Ḫuwawa. These trees should be understood as elements of a wider "wilderness", with which they share a powerful and ambiguous ontological otherness, as opposed to the city and the country of Sumer. In order to become useful, this otherness must be conducted in the city and subject to processes of organization. This article illustrates the symbolic implications of the uprooting, cutting down and subsequent transport of t…
Les grands types de sols viticoles de Pomerol et Saint-Emilion

<p style="text-align: justify;">Les vins les plus réputés de la région viticole de Pomerol et Saint-Emilion sont produits sur des sols foncièrement différents, dérivant de roches mères présentant une grande diversité.</p><p style="text-align: justify;">Les variations que l'on peut noter d'un cru à l'autre sont liées, non pas aux caractéristiques chimiques de ces sols, mais surtout à leurs propriétés physiques (texture, structure, porosité, perméabilité) avec leurs conséquences sur le mode et la profondeur de l'enracinement.</p><p style="text-align: justify;">+++</p><p style="text-align: justify;">The most famous wines from the wine-growing region of…
IEEE Access Special Section Editorial: Exploiting the Benefits of Interference in Wireless Networks: Energy Harvesting and Security
2018
Interference used to be viewed as a harmful factor in wireless networks, which can reduce the quality of information transmission. To combat against interference, many interference management techniques have emerged. Due to the latest research advances, interference (or noise) can also be exploited to offer some benefits to wireless networks. The first aspect is that interference in multi-user networks can be collected as a green power supply for the transceivers, known as wireless energy harvesting. Another application is that one can generate artificial noise to disrupt the adversarial eavesdropping, and guarantee the security of wireless networks. Therefore, conventional interference man…
The MIMOSE Approach to Support Sustainable Forest Management Planning at Regional Scale in Mediterranean Contexts
2017
In recent decades, Mediterranean landscapes have been affected by human-induced drivers, such as land use and climate change. Forest ecosystems and landscapes have been particularly affected in mountainous regions due to limited management and stewardship, especially in remote areas. Therefore, there is a need to set up new strategies to enhance ecosystem services in forested areas which, in turn, will benefit local communities and economies. In this study, we implemented a new approach—Multiscale Mapping of Ecosystem Services (MIMOSE)—to assess ecosystem services in Mediterranean forests located in a mountainous region of Italy. We spatially assessed timber provision and carbon sequestrati…
Plant essential oils in controlling fungal colonization on wooden substrate
2021
In order to control fungal colonization and the related deterioration process of cultural objects, several chemical compounds are actually utilised. These products generally are toxic, not biodegradable and persisting for long time in the environment, also acting on not-targeted biological systems. In this study, specifically to wooden cultural object, Origanum vulgare L. and Thymus vulgaris L. essential oils are proposed as green biocides to contrast the development of Penicillium chrysogenum, Aspergillus flavus and Aspergillus niger fungal species. The aim is replacing toxic products with natural molecules, proposing alternative methodologies supporting the using of non-toxic novel compou…
Inspiriting Innovation: The Effects of Leader-Member Exchange (LMX) on Innovative Behavior as Mediated by Mindfulness and Work Engagement
2021
Continuous innovation has become a key to gaining a sustainable competitive advantage for organizations in the 21st century. By focusing on the underlying mechanisms (i.e., mindfulness and work engagement) by which it works, this study addresses the quality of leader–member relationships and their relevance for innovation in the workplace. Using a sample of 210 employees from 17 Spanish companies, a two-wave longitudinal design evaluated the mediational roles of mindfulness and engagement between leader–member exchange (LMX) quality and innovative work behavior (IWB) in an organizational context. Over the course of a year, two questionnaires were administered to measure LMX quality, mindful…
Differential effects of workaholism and work engagement on the interference between life and work domains
2018
This study analyzed the differences between workaholism and work engagement in relation to their influence on work–life interference. Workaholism is an addiction to work, characterized by obsessive attitude towards job, whereas work engagement concerns a positive pattern of thoughts and feelings about one’s job; these two constructs thus represent pathological and healthy forms of heavy work investment, respectively. As a consequence, it was expected that workaholism and work engagement would have different effects on perceived interference between work and life domains. We assessed levels of workaholism, work engagement, work-to-life interference, and life-to-work interference in a sample …
