Quando l'epos diventa maniera. Lo scudo di Eracle pseudo-esiodeo
No full textThe author of the Shield of Heracles (generally dated about the first quarter of the sixth century B.C.) was confronted with great archaic epos. Both the analysis of some passages that allow a precise comparison (the‘depiction of the two cities’, exemplified on Homer’s Shield of Achilles, the ‘description of the summer’, inspired from the Works and Days by Hesiod), and the examination of some formulae that betray an awkward and mannered approach to epic narrative, allow us to measure the distance (in terms of taste and culture) that separates it from its models
Misoginia o mimesi? Ricerca e rappresentazione dell'elemento femminile nel dramma euripideo
No full textComedians and ancient biographers blame Euripides for his misogyny, though he does not appear in his works more misogynist than any archaic and classical Greek author. The reason for this reputation must probably be sought in his constant research for dramatic mimesis, which led him (on the basis of the medical and philosophical beliefs of the time) to emphasize and to show on the stage the traits of his female characters that he believed more 'womanly': sensitivity, maternal love, but also erotic passion
Prometeo (e Pandora) in Esiodo
No full textIn his double narration of myths related to Prometheus, Hesiod proves to rework traditional narratives in different ways. This is particularly true with regard to the Pandora of the Works and Days, in which the author is probably overlapping two different figures: the ‘beautiful evil’ sent by gods to men, and the progenitor of the female gender. In this context are of great importance Hesiod’s false etymologies, whose purpose is to accredit its own version of the myth: for example, about Prometheus / Epimetheus or about Pandora
The digitalization of peer-to-peer electricity trading in energy communities
No full textOne of the motivating factors for developing energy communities is to create an opportunity for peer-to-peer trading among the members. Smart meters, Internet of Things devices, distributed ledger, and digitalization enable energy communities based on renewable energy production to thrive. The local energy market participants can trade energy and provide services to the upstream distribution and transmission system operators. This chapter introduces the local energy market concept describing enabling technologies. A laboratory-scale local energy community operated by P2P and blockchain is used to show the feasibility and benefits of this new technology
Distributed ledger technologies for peer-to-peer local markets in distribution networks
No full textThe newest Distributed Ledger Technology platforms, which delegate the execution of
complex tasks in the form of Smart Contracts, make it possible to devise novel local electricity market
frameworks, which are performed in a fully automated fashion. This paper proposes a novel fully
automated platform for energy and ancillary service markets in distribution networks, able to run
in a decentralized fashion, bypassing the need for a physical central authority. The proposed
platform, able to perform the role of Virtual Decentralized Market Authority, shows excellent potential
applications in the management of local ancillary service markets in local energy communities of
various sizes. The proposed Virtual Decentralized Market Authority showed reasonable running
costs and comparable technical management capabilities with respect to a physical, centralized
managing authority
DeltaPhish: Detecting phishing webpages in compromised websites
No full textThe large-scale deployment of modern phishing attacks relies on the automatic exploitation of vulnerable websites in the wild, to maximize profit while hindering attack traceability, detection and blacklisting. To the best of our knowledge, this is the first work that specifically leverages this adversarial behavior for detection purposes. We show that phishing webpages can be accurately detected by highlighting HTML code and visual differences with respect to other (legitimate) pages hosted within a compromised website. Our system, named DeltaPhish, can be installed as part of a web application firewall, to detect the presence of anomalous content on a website after compromise, and eventually prevent access to it. DeltaPhish is also robust against adversarial attempts in which the HTML code of the phishing page is carefully manipulated to evade detection. We empirically evaluate it on more than 5,500 webpages collected in the wild from compromised websites, showing that it is capable of detecting more than 99% of phishing webpages, while only misclassifying less than 1% of legitimate pages. We further show that the detection rate remains higher than 70% even under very sophisticated attacks carefully designed to evade our system
Impact of morphology of hydrophilic and hydrophobic bentonites on improving the pour point in the recycling of waste cooking oils
No full textWaste Cooking Oils (WCOs) are generated worldwide through industrial food processing and household use, posing environmental concerns upon disposal. Bentonites often showed to be effective in removing minor contaminants in vegetable oil refining. The present research focused on the processing of raw WCOs using four bentonites, two commercials and two obtained by ball milling of the latest. The different bentonites (hydrophobic and hydrophilic) were characterized before and after ball milling (BM) procedure, including an exhaustive analyses of crystal structure, morphology and surface area via x-ray diffraction (XRD), transmission electron microscopy (TEM), scanning electron microscopy (SEM), and N2-physisorption technique. Optimization of BM processing in terms of milling time was achieved within 60 min. The milled powders were then tested as adsorbents for recycling WCOs with different degrees of decomposition (expressed in terms of free fatty acids, FFAs, content). Employing a design of experiments approach, the impact of five parameters (FFAs content, temperature, specific surface area, stirring, BM time) on the resulting pour point (PP), taken as a quality benchmark for recycled oil, was assessed. Quantitative multivariate statistical analysis revealed temperature's negligible role and identified the significant impact of two characteristics of the bentonite (specific superficial area and ball milling time), as well as the relevant role of the stirring during the treatment. At the end, hydrophilic bentonite resulted able to improve the PP of waste oils with a low content of free fatty acids of about 10 degrees C
Position paper ITACARE-P/FADOI on the referral from internal medicine to cardiac rehabilitation: Executive summary and factsheet
No full textThe Italian Association for Cardiovascular Rehabilitation and Prevention (ITACARE-P) and the Italian Federation of Associations of Hospital Doctors on Internal Medicine (FADOI) released a joint position paper to guide referrals of cardiovascular patients discharged from Internal Medicine (IM) wards to Cardiac Rehabilitation (CR) facilities. The document provides rationale and operative recommendations for appropriateness (i.e. qualifying diagnoses) and priority criteria to overcome the mismatch between potential demand and effective supply of CR programmes. In case of no-referral due to logistic barriers, the document recommends the adoption of best alternatives to CR for disability reduction, better prognosis, and improvement of quality of life. The joint position paper is also aimed to promote the consideration of IM as a potential stakeholder of CR
