I culti distruttivi: metodologie di indagini e spirito di ricerca
Get PDFLo scopo del presente articolo è quello di introdurre nuovi studi, manifestando la necessità di un ampliamento degli strumenti di analisi in possesso del ricercatore, indicandone la natura. Il fine di tali studi è la strutturazione di contributi che siano spendibili dal ricercatore, ed in particolare dal criminologo, che desideri specializzarsi nello studio di quei fenomeni devianti e criminali, segnatamente sette sinistre e i culti distruttivi nelle loro varie manifestazioni, la cui radice di problematicità risiede negli archetipi psichici che regolano e formano il rapporto dell’uomo con la dimensione del sacro, i quali, nella scala di manifestazione relazionale del fenomeno che appare visibile a tutti, sfociano nelle distorsioni delle coordinate psichiche regolanti l’ambito profano di tale fenomeno, nelle sue dimensioni istituzionali, sociali e normative

First direct measurement of the neutron Sachs magnetic form factor
No full textThe BESIII experiment has collected data samples between 2 and 3.08 GeV to study baryons cross sections and form factors. While there are many measurements of the e+e− → pp¯ cross section, the knowledge of the nn¯ final state
is scarce. In this paper, the analysis of this final state by the BESIII Collaboration will be presented. This analysis uses three different strategies to maximize the
neutron detection efficiency. This lead to the world’s most precise measurement of the e+e− → nn¯ cross section and the first direct measurement of the magnetic form
factor of the neutron
New reconstruction algorithm for the fast neutron MONDO tracker
No full textParticle Therapy employs charged light ions to treat cancer with localized energy deposition, so that damages to healthy tissues are significantly reduced with respect to conventional radiotherapy. When using carbon ion beams fragmentation has to be taken into account: the ultra-fast secondary neutrons can be responsible for additional dose also far from the treated volume, and are likely candidates for the occurrence of secondary malignant neoplasms. MONDO is a neutron tracker dedicated to the characterization of the secondary neutrons produced in the interaction between human tissues and the therapeutic beam. It is made of a compact matrix of plastic scintillating fibers coupled with a CMOS-based SPAD sensor (SBAM) developed specifically for MONDO. Its technique of measuring the neutron four-momentum is based on the detection of recoiled protons scattered during two consecutive elastic collision events. A Monte Carlo simulation based on the FLUKA code has been developed to optimize the MONDO detector geometry and study its characteristics. The sensor has been fully implemented in the simulation, and an algorithm for event reconstruction, operating with a cluster building technique, has been written to evaluate detection efficiency, energy resolution and backpointing rejection capability from the chip readout. The algorithm description and first results are presented in this manuscript
Nanoscale characterization of the fibrillar networking in collagen-based cultural heritage artefacts
No full textParchment and leather artefacts are frequently involved in biodeterioration processes. Ionizing radiations represent a valid alternative to the chemical biocide normally employed to stop these deterioration processes. In this work, the use of the X-rays irradiation has been tested to evaluate its possible application to inhibit the microbial growth on parchment and leather samples. Two microscopic techniques, namely SEM and AFM, have been used to obtain information on the effects eventually induced by the treatment on the collagen matrix, helping to identify the threshold dose for which the treatment results effective and safe for parchment and leather cultural heritage objects
Questa volta è una zebra. Etica della ricerca sulle malattie rare
Get PDFLe riflessioni proposte in questo volume sono frutto delle attività di ricerca svolte nell'ambito del progetto Centro per la ricerca di nuovi farmaci per le malattie rare, trascurate e della povertà, progetto frutto di una convenzione operativa tra il Consiglio Nazionale delle Ricerche e il consorzio CNCCS (Collezione Nazionale Composti Chimici e Centro Screening). Il libro è dedicato a un'analisi dei principi etici, dei dispositivi giuridici e degli strumenti di governance a tutela dei diritti dei malati rari. Tale analisi avviene a seguito di una attenta ricostruzione del contesto in cui si inseriscono gli interventi di contrasto alle malattie rare, che ricomprende gli aspetto che maggiormente incidono sull'aspettativa e qualità di vita dei malati. In particolare, sono esaminati i profili etici relativi allo sviluppo di farmaci e alla sperimentazione cinica, le politiche sanitarie (europee e nazionali), la comunicazione scientifica, il ruolo delle associazioni dei pazienti, le iniziative internazionali per la lotta alle malattie rare

High-accuracy azimuth measurements: The ENEA solar compass in its instrumental and smart version
No full textThe accurate assessment of the azimuth of a given direction as, e.g., the geographic North, is of utmost importance in many fields. The electronic solar compass patented by ENEA achieves an accuracy of 0.01◦, it is up to 100 times cheaper than instruments having similar accuracy (GPS, gyros, . . . ), and it is also very fast in answering (few seconds). It is based on a simple but effective optical system to capture the Sun direction, and on an analytical algorithm to provide the Sun position. The ENEA solar compass has been tested and used in many circumstances, e.g., for mapping surveys, to align concentrating solar mirrors, and for orientation measurements of structures in archaeological sites. We obtained notable results, together with INGV, in magnetic declination measurements in Antarctica. Finally, we moved the ENEA solar compass algorithm to smartphones, enabling
their use as orienteering devices
Photosensitizing proteins for a targeted antibacterial photodynamic inactivation
No full textOne of the emerging global health threats is the drug-resistant microbial diseases that could cause millions of deaths each year by 2050. A very promising tool to tackle antimicrobial resistance is photodynamic therapy that exploits the ability of a photosensitizer to generate oxidizing species upon illumination to kill bacteria. The research activity in this field is very active and, following this approach, we aim to develop a targeted theranostic agent where a protein is used as a “modular” carrier, transporting a fluorescent photosensitizer, and an antibody to confer selectivity to the photodynamic effect
OPES: On-the-fly Probability Enhanced Sampling method
No full textMolecular simulations are playing an ever-increasing role, finding applications in fields as varied as physics, chemistry, biology and material science. However, many phenomena of interest take place on time scales that are out of reach for standard molecular simulations. This is known as the sampling problem and over the years several enhanced sampling methods have been developed to mitigate this issue. We propose a unified approach that puts on the same footing two of the most popular families of enhanced sampling methods and paves the way for novel combined approaches. The on-the-fly probability enhanced sampling
method provides an efficient implementation of such generalized approach, while also focusing on simplicity and robustnes
