ReTiF: A declarative real-time scheduling framework for POSIX systems

This paper proposes a novel framework providing a declarative interface to access real-time process scheduling services available in an operating system kernel. The main idea is to let applications declare their temporal requirements or characteristics without knowing exactly which underlying scheduling algorithms are offered by the system. The proposed framework can adequately handle such a set of heterogeneous requirements configuring the platform and partitioning the requests among the available multitude of cores, so to exploit the various scheduling disciplines that are available in the kernel, matching application requirements in the best possible way. The framework is realized with a modular architecture in which different plugins handle independently certain real-time scheduling features. The architecture is designed to make its behavior customization easier and enhance the support for other operating systems by introducing and configuring additional plugins

Beam diagnostics for charge and position measurements in ELI-NP GBS

The advanced source of Gamma-ray photons to be built in Bucharest (Romania), as part of the ELI-NP European Research Infrastructure, will generate photons by Compton back-scattering in the collision between a multi-bunch electron beam and a high intensity recirculated laser pulse. An S-Band photoinjector and the following C-band Linac at a maximum energy of 720MeV, under construction by an European consortium (EurogammaS) led by INFN, will operate at 100Hz repetition rate with trains of 32 electron bunches, separated by 16ns and a 250pC nominal charge. The different BPMs and current transformers used to measure transverse beam position and charge along the LINAC are described. Design criteria, production status and bench test results of the charge and position pickups are reported in the paper, together with the related data acquisition systems

Optical issues for the diagnostic stations for the ELI-NP compton gamma source

A high brightness electron Linac is being built in the Compton Gamma Source at the ELI Nuclear Physics facility in Romania. To achieve the design luminosity, a train of 32 bunches, 16 ns spaced, with a nominal charge of 250 pC will collide with the laser beam in the interaction point. Electron beam spot size is measured with optical transition radiation (OTR) profile monitors. In order to measure the beam properties, the optical radiation detecting system must have the necessary accuracy and resolution. This paper deals with the studies of different optic configurations to achieve the magnification, resolution and accuracy in order to measure very small beam (below 30 μm) or to study the angular distribution of the OTR and therefore the energy of the beam. Several configurations of the optical detection line will be studied both with simulation tools (e.g. Zemax) and experimentally. The paper will deal also with the sensibility of optic system (in terms of depth of field, magnification and resolution) to systematic error

Communication about vaccination: A shared responsibility

Vaccine hesitancy is an important issue to be addressed, due to the risk of decrease of vaccination coverage and consequent control of preventable diseases. While it is not considered a specific determinant, poor or inadequate communication can contribute to vaccine hesitancy and negatively influence vaccination uptake. As a contribution to the ongoing discussion regarding this theme and in the perspective of the implementation of the upcoming national vaccination plan in Italy, the Erice Declaration was drafted by experts in the field of immunization following a 5-day residential, independent workshop regarding communication topics in vaccinology. The aim of the current letter is to present to the broader international audience such a contribution, proposing the identification of the main actions that should be taken into account and prioritized in order to improve communication in the domain of vaccination

Volatile anesthetic agent pollution in operating rooms in a large Roman hospital. A preliminary note

COVID-19 and living space challenge. Well-being and public health recommendations for a healthy, safe, and sustainable housing

Background and aim of the work: The ongoing pandemic of COVID-19 is a strong reminder that the lockdown period has changed the way that people and communities live, work, and interact, and it’s necessary to make resilient the built environment, both outdoor and mainly the indoor spaces: housing, workplaces, public buildings, and entertainment facilities. How can we re-design the concept of Well-being and Public Health in relation to the living places of the future? Methods: According to the previous statements and scenario, this paper aims to integrate the building hygiene and well-being, focusing the possible responses, both existing and for the new buildings, taking home a strong message from this “period” of physical distancing. Results: The Well-being and Public Health recommendations for a healthy, safe, and sustainable housing are framed into the following key points: 1. Visible and accessible green elements and spaces; 2. Flexibility, adaptability, sharing, and crowding of living spaces, and compliant functions located into the buildings; 3. Re-appropriation of the basic principles and archetypes of sustainable architecture, thermal comfort and Indoor Air Quality (IAQ); 4. Water consumption and Wastewater Management; 5. Urban Solid Waste Management; 6. Housing automation and electromagnetic fields; 7. Indoor building and finishing materials. Conclusions: The Well-being and Public Health recommendations for a healthy, safe and sustainable housing may provide a useful basis for Designers, Policy Makers (fostering tax incentives for building renewal), Public Health experts and Local Health Agencies, in promoting actions and policies aimed to transform living places in healthier and Salutogenic spaces.

Inquinamento microbiologico delle sale operatorie: analisi critica di due decenni di sorveglianza

Obiettivo dello studio è stato quello di analizzare i risultati delle campagne di monitoraggio microbiologico delle sale operatorie effettuate negli ultimi due decenni presso il Policlinico di Roma, al fine di descrivere l’andamento nel tempo dei livelli di contaminazione riscontrati e di valutare eventuali cambiamenti significativi. Sono stati presi in esame i campionamenti microbiologici dell’aria effettuati all’interno di 14 blocchi operatori tra il 1992 ed il 2010. I risultati dei campionamenti sono stati aggregati in quattro periodi di tempo (1992-1996; 1996-2000; 2001-2005; 2006-2010) ed è stato analizzata la distribuzione nel tempo dei risultati dei campionamenti rispetto al limite proposto all'ISPESL per le sale at-rest (≤35 UFC/mc). La stessa analisi è stata ripetuta dopo la stratificazione per livello di rischio delle sale operatorie (AR e BR). Al fine di verificare il livello di significatività delle variazioni temporali nelle distribuzioni dei risultati si è fatto ricorso al test del x2 per il trend. Si è osservato un significativo trend in diminuzione del numero di sale con livelli di contaminazione superiori a quello indicato (x2 per trend=8,94; p<0,025). Tale riduzione ha riguardato soprattutto le sale operatorie AR (x2 per trend=7,33; p<0,05). I risultati ottenuti fanno ritenere che le misure adottate nelle sale ad AR siano risultate efficaci. Una maggiore attenzione dovrà essere posta alle sale operatorie a BR
