The mechanically based non-local elasticity: an overview of main results and future challenges
2013
The mechanically based non-local elasticity has been used, recently, in wider and wider engineering applications involving small-size devices and/or materials with marked microstructures. The key feature of the model involves the presence of non-local effects as additional body forces acting on material masses and depending on their relative displacements. An overview of the main results of the theory is reported in this paper.
Ginger and Turmeric Essential Oils for Weed Control and Food Crop Protection
2019
Ginger and turmeric are two food ingredients that are in high demand due to their flavor and positive effects on health. The biological properties of these spices are closely related to the aromatic compounds they contain. The chemical compositions of their essential oils and their in vitro phytotoxic activity against weeds (Portulaca oleracea, Lolium multiflorum, Echinochloa crus-galli, Cortaderia selloana, and Nicotiana glauca) and food crops (tomato, cucumber, and rice) were studied. Forty-one compounds, accounting for a relative peak area of 87.7% and 94.6% of turmeric and ginger essential oils, respectively, were identified by Gas Chromatography&ndash

A New Phylogenetic Framework for the Animal-Adapted
2018
Tuberculosis (TB) affects humans and other animals and is caused by bacteria from the Mycobacterium tuberculosis complex (MTBC). Previous studies have shown that there are at least nine members of the MTBC infecting animals other than humans; these have also been referred to as ecotypes. However, the ecology and the evolution of these animal-adapted MTBC ecotypes are poorly understood. Here we screened 12,886 publicly available MTBC genomes and newly sequenced 17 animal-adapted MTBC strains, gathering a total of 529 genomes of animal-adapted MTBC strains. Phylogenomic and comparative analyses confirm that the animal-adapted MTBC members are paraphyletic with some members more closely relate…
Evaluation of biocidal potential of some plant species from the Mediterranean wild flora
Fractional calculus approach for the representation of power spectral densities and correlation functions in wind engineering
2010
The paper deals with the digital simulation of wind velocity samples by Fractional Spectral Moment function. It is shown that such a function represents a third useful way to characterize a stationary Gaussian stochastic process, alongside the power spectral density and the correlation function. The method is applied to wind velocity fields whose power spectra is given by the Kaimal’s, the Davenport’s and the Solari’s representation. It is shown that by constructing a digital filter whose coefficients are the fractional spectral moments, it is possible to simulate samples of the target process as superposition of Riesz fractional derivatives of Gaussian white noise processes.
Univariate and multivariate properties of wind velocity time series
2009
We analyze the time series of hourly average wind speeds measured at 29 different stations located in Sicily, a region with a complex morphology. The investigation, performed from the univariate as well as the multivariate point of view, evidences that the statistical properties of wind at the single sites have features that are not reproduced by standard models and, thus, require specific modeling. Moreover, the synchronous evolution of wind velocity presents a cluster structure, obtained with different algorithms, that persists in the standard deviation too.
Świętowanie na ulicy. Orszak Trzech Króli w zimowym pejzażu miasta
2017
Autorka zainteresowała się formami kolędniczymi, związanymi ze Świętem Trzech Króli (6 stycznia): tradycyjną grupą kolędniczą – Trzej królowie, nowszą – kolędnikami misyjnymi oraz organizowanym od 2009 r. na ulicach wielu miast w Polsce Orszakiem Trzech Króli, czyli oryginalną procesją uliczną. To hałaśliwe wydarzenie uliczne wpływa na odmienny charakter uczestniczenia w religijnym „misterium”: czytelny jest tu aspekt uteatralnienia ceremonii religijnej (przebrani aktorzy pierwszo- i drugoplanowi, rekwizytem powszechnym są papierowe korony królewskie, budowa scen, na których odbywają się koncerty amatorskich i profesjonalnych zespołów). Przemarsz ulicami miasta księży i osób wierzących, nau…
Creating and maintaining social networks: women’s participation in Basque pilota. [Creación y mantenimiento de redes sociales: participación de mujer…
2015
Basque pilota is a traditional sport played mainly by men. A project emerged in 2005 to promote female participation: Emakumea Pilotari (Woman pelota player). In this article we present the main points that emerged from an ethnographic study of the social relationships that playing Basque pilota can provide. The study was carried out in 2011-2012 season with a purposive sample of 28 adult women Basque pilota players (pilotaris) (between 22 and 60 years old). 26 participants were pilotaris in recreational groups and the other two were their trainers. The results suggest that a sense of community, team membership, the development of a general reciprocity and group security are the most import…
Low mimosine content and nutrient-rich foliage of two Leucaena leucocephala varieties: a potential fodder resource in Mediterranean agroforestry syst…
2022
Leucaena leucocephala is worldwide used for wood production, reforestation and for feeding livestock. To assess the potential use of leucaena for animal nutrition, we analysed the composition of methanolic extracts of leaf samples of two varieties occurring in Sicily (Mediterranean area), also determining the presence of mimosine.
