Mcnpx calculations of specific absorbed fractions in some organs of the human body due to application of 133xe, 99mtc and 81mkr radionuclides
No full textMonte Carlo simulations were performed to evaluate treatment doses with wide spread used radionuclides 133Xe, 99mTc and 81mKr. These different radionuclides are used in perfusion or ventilation examinations in nuclear medicine and as indicators for cardiovascular and pulmonary diseases. The objective of this work was to estimate the specific absorbed fractions in surrounding organs and tissues, when these radionuclides are incorporated in the lungs. For this purpose a voxel thorax model has been developed and compared with the ORNL phantom. All calculations and simulations were performed by means of the MCNP5/X code. © The Author 2017.

Fluence to Hp (3) conversion coefficients for neutrons from thermalto 15 mev
No full textThe recent statement on tissue reactions issued by the International Commission on Radiological Protection in April 2011 recommends a very significant reduction in the equivalent dose annual limit for the eye lens from 150 to 20 mSv y-1; this has stimulated a lot of interest in eye lens dosimetry in the radiation protection community. Until now no conversion coefficients were available for the operational quantity Hp(3) for neutrons. The scope of the present work was to extend previous evaluations of Hz.ast;(10) and Hp(10) performed at the PTB in 1995 to provide also Hp(3) data for neutrons. The present work is also intended to complete the studies carried out on photons during the last 4 y within the European Union-funded ORAMED (optimisation of radiation protection for medical staff) project. © The Author 2013.

In previous works we developed a Fortran procedure for the encoding and the computer analysis of the macroseismic
effects deduced from historical sources that allow the complete formalization of the process of seismic
intensity assessment. The texts representing the macroseismic information are decomposed in 5 main syntactic
elementary components by using alphanumeric codes. The database includes presently more than 33000 effects
relative to 8 significant Italian earthquakes of the last two centuries that can be analyzed by multi-criteria decisionmaking
algorithms to estimate objectively the seismic intensity at each locality. The complete procedure was now
translated to MATLAB and was definitely improved by the inclusion of new tools for the encoding, the georeferencing
and the checking of the data and of new Fuzzy algorithms for intensity determination. The output of
the procedure is strictly integrated with the new version of “Boxer” code for the determination of seismic source
parameters.PublishedWien5.1. TTC - Banche dati e metodi macrosismiciope

Forward to the Past: la sfida della Storia in Machines Like Me di Ian McEwan
No full textIn his novel, Machines Like Me (2019), Ian McEwan offers an interesting example of “alternate history” while dealing with crucial ethical issues connected with the development of Artificial Intelligence. Instead of setting his story in the future, the author chooses to set it in the past, but he radically changes the contours of the latter. Hence, the England of the early 1980s is turned into a technologically advanced society, well ahead of the scientific progress of the early 21st century. Thus, the future casts its light on the past in what appears as a typically postmodernist mélange: besides mingling genres (from speculative fiction to uchronia), McEwan also performs an intriguing hybridization of fact and fiction. The paper intends to explore the rich historical dimension of the novel, which betrays the author’s interest in the reflection on history and on its narrativization – as well as its manipulation and/or contamination – within the literary text

EDEL: ENEA dosemeter for eye lens
No full textSince the publication of International Commission on Radiological Protection statement in 2011 on tissue reaction, eye lens radiation protection played an important role in exposed personnel dosimetry. For this reason, the Italian National Agency for New Technologies, Energy and Sustainable Economic Development (ENEA) Individual Monitoring Service decided to study a prototype to fulfil specific requests (e.g. for survey in interventional department and intercomparisons). On the basis of such preliminary investigation, a new eye lens dosemeter was developed. The new dosemeter, named EDEL (ENEA Dosemeter for Eye Lens), was characterised in terms of Hp(3), the operational quantity related to eye lens monitoring. The investigation was performed experimentally and optimised using the Monte Carlo MCNP6 code. The new prototype was thought to fulfil two main requests: the reliability of the dosimetric data and the portability of the dosemeter itself. The new dosemeter will soon be supplied to the collaborating hospitals for workplace test measurements. © The Author 2015. Published by Oxford University Press. All rights reserved
Ka-band GaN-on-SiC power amplifier for high EIRP satellite phased antenna array
No full textThis work presents a transmitter-only phased antenna array architecture for Ka-band satellite applications, specifically from 25.5 to 27 GHz. The design targets an optimum design point among the number of elements, the output power from each transmitter, the antenna EIRP, and its steering capabilities. The core of the system relies on a custom designed power amplifier based on AlGaN/GaN epitaxy grown on 4-inch SiC substrate featuring 20 dB of gain and 28 dBm of saturated power. The antenna array front-end is envisaged as a lattice of 64 hollow metallic horns, spaced by 16 mm from each other. The amplifiers paired with the antenna array targets 70 dBm of EIRP, even considering the maximum beamsteering configuration of ±20°. The proposed concept highlights the flexibility in targeting different power levels, antenna gain, and steering capabilities to finally address a large number of use-cases
