A model for large θ13 constructed using the eigenvectors of the S4 rotation matrices
No full textA procedure for using the eigenvectors of the elements of the representations of a discrete group in model building is introduced and is used to construct a model that produces a large reactor mixing angle, , in agreement with recent neutrino oscillation observations. The model fully constrains the neutrino mass ratios and predicts normal hierarchy with the light neutrino mass, m1 ≈ 25 meV. Motivated by the model, a new mixing ansatz is postulated which predicts all the mixing angles within 1σ errors
Energy Management Maturity Model: An organizational tool to foster the continuous reduction of energy consumption in companies
No full textEnergy has recently become one of the key aspects that companies should improve and keep monitoring, due to the related economic costs and the significant environmental impacts, to which today’s society is paying more and more attention. An Energy Management System could offer many advantages, such as energy consumption and cost reductions, improvement of corporate image, environmental impact reduction. Organizations have therefore developed more comprehensive approaches to Energy Management, aiming at reducing energy waste, but also at managing energy use by applying specific focused programs. Maturity Models are tools used to assess the level of maturity of an organization, providing a systematic framework for carrying out benchmarking and performance improvement. With regards to Energy Management, existing tools are still not well-structured and do not allow a deep analysis of the level of maturity of an organization and of how this maturity develops along with its dimensions. In this article the described general Maturity Model tools are implemented, providing an innovative method in order to apply those concepts to the Energy Management field, aiming at bridging the aforementioned gaps. A user-friendly tool, focused on the company and its organization, is provided to allow practitioners to easily and autonomously assess their company’s maturity level, drawing a first growth plan draft. This method represents a new way to lead the organization to a proper management of its energy needs, and is alternative or complementary to the certification of the Energy Management System of the organization, being consistent with the ISO 50001 standard

The pottery of Takarkori rock-shelter (Tadrart Acacus, Libya): an intra-site analysis for the study of occupation and formation processes in Early to Middle Holocene Central Sahara
No full textL'obiettivo del progetto di ricerca è quello di ricostruire i processi formativi e l'uso dello spazio all'interno del riparo di Takarkori (Tadrart Acacus, Libia S-O, Sahara centrale) nelle diverse fasi di occupazione durante l'Olocene iniziale e medio, attraverso l'analisi spaziale e contestuale del repertorio ceramico in associazione con strutture e depositi significativi. L'applicazione di un'analisi multiforme del repertorio ceramico, dagli attributi tecnologici e stilistici agli aspetti tafonomici e contestuali, permetterà l'identificazione dei diversi processi formativi e la caratterizzazione funzionale dell'uso del riparo nelle differenti fasi di occupazione. L'esplicitazione di modelli e ricostruzioni della vita del sito nel più ampio scenario della preistoria del Sahara centrale permetterà inoltre di verificare e confrontare diacronicamente le occupazioni di cacciatori-raccoglitori prima e di pastori Neolitici poi, e di ricostruire sincronicamente dinamiche e aspetti contestuali.The aim of the research project is to reconstruct the formation processes and use of space within the Takarkori shelter (Tadrart Acacus, Libya S-W, Central Sahara) in the different phases of occupation during the Early and Middle Holocene, through the spatial and contextual analysis of the ceramic repertory in association with significant structures and deposits. The application of a multifaced analysis of the pottery repertoire from technological to stylistic attributes to taphonomic and contextual aspects will allow the identification of the different formative processes, and the functional characterisation of the shelter’s use in the different phases of occupation. The explication of models and reconstructions of the life of the site in the broader scenario of the prehistory of the central Sahara will also allow to verify and compare diachronically first hunter-gatherer and then pastoral occupations, and synchronically reconstruct contextual dynamics and aspect
The role of surface fluxes in the development of a tropical-like cyclone in southern Italy
No full textNumerical simulations of a tropical-like cyclone in southern Italy have been performed with two different modelling systems (BOLAM-MOLOCH and WRF) with the aim of discussing the role of the surface fluxes in the development of the vortex and evaluating their intensity during the mature stage of the cyclone. Although significant differences emerge in their intensity, both the modelling systems agree in showing that the surface fluxes are more important than the latent heat release associated with convection in the initial phase of the vortex lifecycle, while they are less relevant (although more intense) when the minimum assumes the characteristic of a tropical cyclone
Towards the 70th Anniversary (1955-2025) of the Joint Libyan-Italian Archaeological Mission in the Tadrart Acacus and Messak (SW Libya).
No full textThe archaeological and scientific cooperation
between Libya and Italy started in the
1920s. A few years after World War ii, Fabrizio Mori
initiated the archaeological mission in the Tadrart
Acacus, a sandstone massif in southwestern Libya,
laying the foundation of one of the longest enterprises
in the North African country. After a short
background of the mission and a concise summary
of the main scientific results, the paper focuses on
the main activities of the Mission – especially the
publications in the Series «aza - Arid Zone Archaeology,
Monographs» – carried out after the beginning
of the Revolution (2011), as well as on the principal
objectives to achieve on the short term. It also
highlights new research avenues that leverage extensive
data from over fifty years of fieldwork in the
Sahara, employing advanced cutting-edge techniques
to investigate socio-cultural and technological
developments. A fundamental action will be directed
toward the removal of the Tadrart Acacus
from the unesco World Heritage sites in danger. In
addition, a special attention is placed on year 2025,
which will represent the 70th anniversary of the
Mission (1955-2025), and the centenary of the birth
of Fabrizio Mori (1925-2025), the founder of the
mission and its director until 1996
Diffusive author(s), cohesive author: Analysis of S/N (1994)
No full textThis study indicates the ways in which various aspects of the author(s) are brought forth in Dumb type’s performance art, the S/N production. Previous research has suggested a non-hierarchical organization of Dumb type and the absence of a “privileged author” in Dumb type’s collaborative work, S/N. However, the results that I have investigated from member’s interviews on the creative process of S/N along with my analysis of the recorded images of S/N, indicate a different aspect of the author(s). First, S/N was created through, so to speak, the collective ideas of the members of Dumb type. Further, S/N has at least nine quotations from previous performances, installations, and printed writings, besides the work-in-progress technique. Explicating one of the “author functions” as given by Michel Foucault, each text has plural subjects of the author. However, it has been revealed from members’ interviews that Teiji Furuhashi had a decision-making role in selecting the members’ ideas within the performance. Since then, S/N has had plural subjects of creation; however, Furuhashi is one of the subjects of creation along with the “privileged author.” S/N has plural authors (diffusive authors) yet at the same time, it has a “privileged author,” Teiji Furuhashi (cohesive author)
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Insights in the Evaluation of Gluten Dietary Avoidance in Healthy Subjects
No full textBackground: The amount of healthy subjects adopting a gluten-free diet (GFD) for nonmedical reasons actually surpasses the numbers of those who are dealing with a permanent gluten-related disorder. Objective: The study aimed to better clarify the interactions between a GFD and physical and psychological well-being. Methods: Sixty healthy subjects with normal weight were enrolled. Thirty subjects (15 female) were submitted to a normocaloric GFD and considered as the experimental group (EG), and 30 subjects (15 female) were submitted to a normocaloric diet (CG) for 6 months. The hematochemical and psychological parameters before and after the diet were recorded. Results: Significant improvement was demonstrated in red blood count, hemoglobin, total cholesterol, and high-density lipoprotein parameters in the EG after the gluten-free diet. However, a significant increase of α-amylase pancreatic activity and reduction of vitamin B12 and magnesium levels in the EG were observed. Regarding the psychological parameters, the GFD significantly improved scores assessing body satisfaction, but increased social insecurity. Conclusions: The study is the first to consider significant modulation in hematochemical parameters as well as psychological ones by gluten avoidance in healthy individuals. Although these subjects were not characterized by intestinal mucosa damage, some of the effects were similar to those observed in celiac disease patients who began to adhere to a GFD
