Un “teatro sacro” di Andrea Pozzo nella chiesa dell'Immacolatella a Trapani di Giovanni Amico (dal 1732): storia, fonti, rilievo

2022

Il contributo, articolato tra storia e rappresentazione, ha l’obiettivo di analizzare la genesi progettuale e le fonti utilizzate dall’architetto Giovanni Amico per l’ammodernamento della tribuna della chiesa dell’Immacolatella a Trapani (dal 1732). L’opera è oggi priva di studi e di rilievi ma per le sue caratteristiche compositive, che sfruttano il tema della manipolazione dello spazio e della luce con finalità scenografiche, appartiene a una serie prodotta in Sicilia da Amico che è possibile collegare al mondo progettuale romano e soprattutto di Andrea Pozzo in relazione ai “teatri sacri” prodotti per i Gesuiti e conosciuti tramite le incisioni del suo celebre trattato, ma anche attraver…

The MOBI-Kids Study Protocol: Challenges in Assessing Childhood and Adolescent Exposure to Electromagnetic Fields from Wireless Telecommunication Tec…

2014

The rapid increase in mobile phone use in young people has generated concern about possible health effects of exposure to radiofrequency (RF) and extremely low frequency (ELF) electromagnetic fields (EMF). MOBI-Kids, a multinational case–control study, investigates the potential effects of childhood and adolescent exposure to EMF from mobile communications technologies on brain tumor risk in 14 countries. The study, which aims to include approximately 1,000 brain tumor cases aged 10–24 years and two individually matched controls for each case, follows a common protocol and builds upon the methodological experience of the INTERPHONE study. The design and conduct of a study on EMF exposure an…

Dynamic thermal simulation of buildings: a case study to validate ESP-r software

2008

Energy aspects and environmental problems have a key role in the definition of building’s design, management and maintenance. The energy saving and the decrease of environmental impact throughout the life cycle assessment of buildings maintaining an high level of comfort are Key points for a modern and sustainable construction (total quality of the building). In fact, the building’s design has to be considered the result of a multi-objective problem. Furthermore the European Directive 2002/91/EC issues the sustainable themes on the energy performance of buildings [1], and include the energy certification of new buildings with effect from 2006

Dosimetria ESR con alanina per adronterapia per protoni e ioni carbonio

Electron Spin Resonance (ESR) dosimetry for clinical radiation beams.

2016

In the last two decades the electron spin resonance (ESR) technique has been widely adopted for dosimetry of the radiation beams used in radiation therapy. In particular, alanine dosimtery is nowadays recognized as an international standard system for transfer dosimetry and for high doses. This is because among the various solid-state dosimeters the alanine ESR detectors present several advantages such as: tissue equivalence, linearity of its dose-response over a wide range, high stability of radiation induced free radicals, no destructive read-out procedure, no sample treatment before EPR signal measurement. In this presentation the main applications of ESR dosimetry for the characterizati…

Uso della spettroscopia ESR per la caratterizzazione di composti fenolici irradiati con fasci clinici di fotoni ed elettroni

2016

In the last decades several research laboratories have shown an increasing interest aimed at extending the applicability of Electron Spin Resonance (ESR) dosimetry to radiotherapy with different types of radiation beams. ESR is a spectroscopic method for investigating the structure and dynamics of such paramagnetic species. Free radicals are known to be produced when a compound is irradiated with ionizing radiations. The concentration of radiation-induced free radicals is proportional to the energy released inside in the medium and this allows for dosimetric measurements through ESR technique which able to quantitatively determine the radical concentration. The use of alanine as a dosimetri…

Neutron Electron Spin Resonance dosimetry with phenol compounds

Nuove frontiere per la dosimetria ESR per fasci clinici di fotoni ed elettroni: i composti fenolici IRGANOX® 1076. (Characterization of phenolic soli…

2017

This work deals with the dosimetric features of a particular phenolic compound (IRGANOX 1076®) for dosimetry of clinical photon and electron beams by using Electron Spin Resonance (ESR) spectroscopy. After the optimization of the ESR readout parameters (namely modulation amplitude and microwave power) to maximise the signal without excessive spectrum distortions, basic dosimetric properties of laboratory-made phenolic dosimeters in pellet form, such as reproducibility, dose-response, sensitivity, linearity and dose rate dependence were investigated. The dosimeters were tested by measuring the depth dose profile of a 6 MV photon beam. A satisfactory intra-batch reproducibility of the ESR sig…

Electron Spin Resonance dosimetry using organic compounds (alanine and ammonium tartrate) for mixed neutron-gamma fields

2016

Alongside with the development of Neutron Capture Therapy (NCT) and the use of thermal neutrons for radiotherapeutic purposes, many efforts have been devoted to the characterization of the beam in order to optimize therapy procedures. Reliable dose measurements should be able to determine the various (neutrons and photonic) components of the mixed beam usually employed for therapy. This paper studies the effect of additives such as boric and gadolinium nuclei on the sensitivity of neutron organic (alanine and ammonium tartrate) dosimeters analyzed through Electron Spin Resonance (ESR) technique (Marrale, 2014). These dosimeters were exposed to a mixed (neutron-gamma) field mainly composed o…
