Neutrinos below 100 TeV from the southern sky employing refined veto techniques to IceCube data
2020
Many Galactic sources of gamma rays, such as supernova remnants, are expected to produce neutrinos with a typical energy cutoff well below 100 TeV. For the IceCube Neutrino Observatory located at the South Pole, the southern sky, containing the inner part of the Galactic plane and the Galactic Center, is a particularly challenging region at these energies, because of the large background of atmospheric muons. In this paper, we present recent advancements in data selection strategies for track-like muon neutrino events with energies below 100 TeV from the southern sky. The strategies utilize the outer detector regions as veto and features of the signal pattern to reduce the background of atm…
Strengthening of Masonry Columns with BFRCM or with Steel Wires: An Experimental Study
2016
Nowadays, innovative materials are more frequently adopted for strengthening historical constructions and masonry structures. The target of these techniques is to improve the structural efficiency with retrofitting methods while having a reduced aesthetical impact. In particular, the use of basalt fiber together with a cementitious matrix emerges as a new technique. This kind of fiber is obtained by basalt rock without other components, and consequently it could be considered a natural material, compatible with masonry. Another innovative technique for strengthening masonry columns consists of applying steel wires in the correspondence of mortar joints. Both techniques have been recently pr…
Sexism and Aggression in Adolescence.¿How Do They Relate to Perceived Academic Achievement?
2018
Sexist attitudes are rooted in patriarchal structures, which uphold traditional gender stereotypes, and which are still found in society today. Scholars have found gender differences in perceived academic achievement, with girls performing better than boys, and negative relationships between sexism and perceived academic achievement. Moreover, perceived academic achievement and sexist attitudes have been associated with aggression and different kinds of violence. This study examined the associations between sexist attitudes and perceived academic achievement (using self-report data). The study also assessed the mediating role of physical and verbal aggression in the relationship between sex…
Dried-fruit shell reuse in green construction and building materials
2023
Bio-architecture is a new way of designing and building in line with the European Green Deal and in light of the circular economy principles. This new green approach is guiding the entire construction life cycle toward eco-sustainability and environmental friendliness, from the beginning to the end of the building process. In addition to the use of environmentally-friendly and high-performance building and construction materials, it is necessary to use new technologies that can reduce the environmental footprint. This paper aims to examine the possible reuse of biological wastes of agricultural origin of the Mediterranean basin, whose massive production generates a number of problems for th…
La rajola a la costa i els residus a l’interior. Mapa dels conflictes socioecològics al País Valencià
2020
EnglishIn the last decade, the Valencian Country has experimented a growth of the productive processes that has led to an unprecedented degradation of the territory. At the same time, the increase in the ecological, material and carbon footprint has led to the generation of socio-ecological conflicts. A typology of socio-ecological conflicts is proposed, consisting of 5 categories —derived from urban processes, infrastructures, pollution and public health, the extraction of mineral resources and the use of water resources—, which classifies and places them on the 'map of the socio-ecological conflicts of the Valencia Country'. The map locates such environmental conflicts. Furthermore, the u…
Economic and Environmental Assessment of Biomass Power Plants in Southern Italy
2022
In 2019, Europe adopted the New Green Deal as a strategic plan to become a competitive, resource-efficient, and driven economy by reducing its gas emissions and carbon footprint. Due the COVID-19 pandemic, this strategic plan was recently updated to expedite the green transition of European industries. Therefore, the present paper deals with the problem of deciding an appropriate size for a biomass plant that directly produces electric energy by means of two different conversion processes: combustion and gasification. After an initial estimation of the energy potential in western Sicily, GIS data of biomass growth were used to identify the appropriate size for the power plants under investi…
En contexte ou hors contexte : lecture des matériaux et lecture du bâti
2020
Le choix des matériaux occupe une place importante dans l’élaboration du projet architectural, et détermine des orientations essentielles pour le chantier, dans la réalisation de celui-ci, son organisation, voire sa progression. Loin de se résumer à un simple descripteur ou accessoire de la stratigraphie du bâtiment, les matériaux de construction sont avant tout le reflet d’une réalité complexe du chantier à la fois matérielle et immatérielle : projet, exigences et capacité financière du commanditaire, réseaux d’échange, environnement sollicité. Leur prise en compte dans l’analyse du bâti transcende la logique stratigraphique, en épaulant celle-ci là où elle fait défaut et en replaçant la r…
ALGORITHM OF PARTIAL BREAST RECONSTRUCTION WITH PEDICLED PERFORATOR FLAPS
2010
INTRODUCTION: The authors present an algorithm of partial breast reconstruction following quadrantectomy that allows to restore the breast volume defect with the use of pedicled perforator flaps. MATERIAL AND METHODS: Between March 2009 and May 2010, at the Plastic and Reconstructive Institute of University of Palermo, pedicled perforator flaps were used to integrate volume and/or breast skin in 12 patients after benign and malignant breast tumors. The flaps used were based on perforators of the thoraco-dorsal artery (TDAP) and of the intercostal arteries (ICAP). TDAP flaps were used to reconstruct defects in any breast quadrant, while ICAP perforator were used to reconstruct lateral and ce…
Concrete arch bridges erected by suspended cantilever method vs cable–stayed bridges

Creep effects and stress adjustments in cable-stayed bridges with concrete deck
2010
In construction stages of cable-stayed bridges with prestressed concrete deck, the influence of creep on stresses and strains is very important in order to foresee the final patterns of internal forces and displacements. In cantilever construction, the concrete deck can be considered, in each stage, as a continuous beam resting on elastic restraints, which modify with successive additions of new segments, until the last one has been assembled. In these stages stress relaxation in concrete occurs as well as vertical displacements increase. Ehen structure has been closed by inserting midspan segment, stress redistribution begins, due to creep. Deformation and internal force development in con…
