Tagesreste e Simulacra: sogni e sogni erotici in Lucrezio

2017

Secondo la dottrina epicurea che nega ai sogni di ogni potere profetico, legandoli invece a ciò che è successo durante il giorno, Lucrezio teorizza e dimostra la stretta connessione tra «Tagesreste», «simulacra» ed esperienza onirica. Particolarmente degna di nota è la sezione dedicata ai sogni erotici (IV 1030-1057), in cui il poeta utilizza la letteratura medica greca tra Ippocrate e Erofilo di Calcedonia. Alcuni passaggi, fino ad ora non considerati, anche se accompagnati dall’evidenza di testi tardo-antichi, spiegano il background scientifico su cui si colloca il passo lucreziano dedicato alla fisiologia dei sogni erotici. In accordance with the Epicurean doctrine which denies the dream…

Medición de resultados en la estrategia CRM : Hacia un modelo holístico

2006

Este trabajo pretende contribuir a la investigación realizada en el ámbito la medición de resultados derivados de la estrategia CRM (Customer Relationship Management) . Con tal objetivo, primeramente definimos CRM como una filosofía de negocio que combina estrategia y tecnología en entornos tanto convencionales como virtuales (e-CRM). A continuación, destacamos la necesidad de contar con sistemas de medición por parte de las empresas que evalúen, de forma dinámica, el impacto de las iniciativas CRM y e-CRM sobre los resultados. Asimismo, realizamos una retrospectiva de las métricas utilizadas en el ámbito del marketing , destacando la tendencia hacia modelos scorecard , con un especial énfa…

2020

This book constitutes the refereed post-conference proceedings of the 15th EAI International Conference on Quality, Reliability, Security and Robustness in Heterogeneous Networks, QShine 2019, held in Shenzhen, China, in November 2019. The 16 revised full papers were carefully reviewed and selected from 55 submissions. The papers are organized thematically in tracks, starting with mobile systems, cloud resource management and scheduling, machine learning, telecommunication systems, and network management.

An inter-laboratory comparison to evaluate the suitability of EN 1787 standard to detect irradiation in plant-origin foods with health benefits

2020

Abstract This paper reports the results of a study carried out to verify the applicability of the EN 1787 method, which uses the Electron Spin Resonance (ESR) technique for the identification of irradiated plant-origin foods with health benefits. The method was tested on samples of herbal ingredients of Plant Food Supplements (PFSs), nuts and fresh blueberries. Untreated and irradiated samples of Camellia sinensis (leaves) Ginkgo biloba (leaves), Glycine max (seeds), Silybum marianum (fruits), Vaccinium myrtillus (fruits), almonds, hazelnuts, peanuts, pistachios, walnuts and fresh blueberries were analysed. The work includes an inter-laboratory blind test involving five Italian laboratories…

Determinazione della componente gamma nella colone termica del reattore TRIGA di Pavia tramite Dosimetri ESR di alanina

2016

Negli ultimi anni il crescente interesse verso la radioterapia a cattura neutronica (internazionalmente nota come Neutron Capture Therapy - NCT) per il trattamento di neoplasie ha stimolato diverse attività di ricerca finalizzate alla caratterizzazione del fascio utilizzato e all'ottimizzazione delle procedure radioterapiche. Tra i vari sistemi dosimetrici trovano largo impiego i rivelatori a stato solido ESR (Risonanza di Spin Elettronico) a base di alanina che presentano diversi vantaggi come la tessuto equivalenza, la linearità della risposta in un ampio intervallo di dose, l'elevata stabilità dei radicali liberi radioindotti, la non distruttività della lettura del dosimetro e il basso c…

A randomized multicenter trial on a lung ultrasound-guided treatment strategy in patients on chronic hemodialysis with high cardiovascular risk

2021

Lung congestion is a risk factor for all-cause and cardiovascular mortality in patients on chronic hemodialysis, and its estimation by ultrasound may be useful to guide ultrafiltration and drug therapy in this population. In an international, multi-center randomized controlled trial (NCT02310061) we investigated whether a lung ultrasound-guided treatment strategy improved a composite end point (all-cause death, non-fatal myocardial infarction, decompensated heart failure) vs usual care in patients receiving chronic hemodialysis with high cardiovascular risk. Patient-Reported Outcomes (Depression and the Standard Form 36 Quality of Life Questionnaire, SF36) were assessed as secondary outcome…

Impact of humic acids on EYL liposome membranes: ESR method

2015

Abstract In this paper, the effects of model (commercial) and natural (extracted from peat) humic substances on the membrane of liposomes formed with egg yolk lecithin (EYL) are presented. In our research, mass concentrations of fulvic and humic acids were used, which in relation to lecithin varied from 0% to 13%. To study membrane fluidity, electron spin resonance (EPR) was used with two spin probes, penetrating various regions of the lipid bilayer. The effects of model and natural humic substances (humic acids – HAs and fulvic acids – FAs) on the lipid membrane in different regions were researched: the lipid-water interphase, and in the middle of the lipid bilayer. It was shown that FA an…

Changes in Family Income around the Time of Birth of Children in Germany between 1985 and 2004

2010

Während der Verlauf und die Ursachen des Geburtenverhaltens intensiv erforscht wurden, sind die finanziellen Folgen einer Geburt empirisch kaum beachtet worden. Daher werden hier kurzfristige Wohlstandsveränderungen von Familien (hinsichtlich verfügbarem Haushaltseinkommen und Äquivalenzeinkommen) rund um die Geburt eines Kindes in längsschnittlicher Perspektive analysiert und auf ihre Ursachen untersucht. Zu diesem Zweck wurden die Daten des Sozio-oekonomischen Panels (1984-2005) mittels Fixed-Effekt-Panelregressionsmodellen analysiert. Als Ergebnis kann festgehalten werden, dass die finanziellen Folgen einer Geburt in den letzten Jahren deutlich gewachsen sind und vor allem das erste Kind…
