Medicalizing gender: from intersex to DSD, from the laboratory to patient groups

The subject of this research, the medicalization of the gendered body, is a shifting object. It has changed its medical name from Intersex to DSD (Disorders -or Divergence- of Sex Development), since the beginning of this research project. Loosely speaking it addresses the gendered components of the body, and their subsequent consideration. Drawing closer, it addresses how modern medicine treats people who manifest variations of one of the gendered components of the body, inserting their bodies into pathological categories now called DSD. This shifting terrain of different modes of viewing the gendered body has grown to include many variations, no longer solely interested in the mythical hermaphrodite. The locus of this investigation is in the interaction between these patient groups and doctors in Italy.

Study of materials and technology of ancient floor mosaics' substrate

Ancient pavements are composed of a variety of preparatory or foundation layers constituting the substrate, and of a layer of tesserae, pebbles or marble slabs forming the surface of the floor. In other cases, the surface consists of a mortar layer beaten and polished. The term mosaic is associated with the presence of tesserae or pebbles, while the more general term pavement is used in all the cases. As past and modern excavations of ancient pavements demonstrated, all pavements do not necessarily display the stratigraphy of the substrate described in the ancient literary sources. In fact, the number and thickness of the preparatory layers, as well as the nature and the properties of their constituent materials, are often varying in pavements which are placed either in different sites or in different buildings within a same site or even in a same building. For such a reason, an investigation that takes account of the whole structure of the pavement is important when studying the archaeological context of the site where it is placed, when designing materials to be used for its maintenance and restoration, when documenting it and when presenting it to public. Five case studies represented by archaeological sites containing floor mosaics and other kind of pavements, dated to the Hellenistic and the Roman period, have been investigated by means of in situ and laboratory analyses. The results indicated that the characteristics of the studied pavements, namely the number and the thickness of the preparatory layers, and the properties of the mortars constituting them, vary according to the ancient use of the room where the pavements are placed and to the type of surface upon which they were built. The study contributed to the understanding of the function and the technology of the pavements’ substrate and to the characterization of its constituent materials. Furthermore, the research underlined the importance of the investigation of the whole structure of the pavement, included the foundation surface, in the interpretation of the archaeological context where it is located. A series of practical applications of the results of the research, in the designing of repair mortars for pavements, in the documentation of ancient pavements in the conservation practice, and in the presentation to public in situ and in museums of ancient pavements, have been suggested.

Enabling a direct path from end-user specifications to executable protocols in a biology laboratory environment

Biomedical analyses are becoming increasingly complex, with respect to both the type of the data to be produced and the procedures to be executed. This trend is expected to continue in the future. The development of information and protocol management systems that can sustain this challenge is therefore becoming an essential enabling factor for all actors in the field. The use of custom-built solutions that require the biology domain expert to acquire or procure software engineering expertise in the development of the laboratory infrastructure is not fully satisfactory because it incurs undesirable mutual knowledge dependencies between the two camps. We propose instead an infrastructure concept that enables the domain experts to express laboratory protocols using proper domain knowledge, free from the incidence and mediation of the software implementation artefacts. In the system that we propose this is made possible by basing the modelling language on an authoritative domain specific ontology and then using modern model-driven architecture technology to transform the user models in software artefacts ready for execution in a multi-agent based execution platform specialized for biomedical laboratories.

Development of an X-ray spectrometric system and feasibility tests of Silicon Drift Detector for medical and space applications

The thesis work concerns X-ray spectrometry for both medical and space applications and is divided into two sections. The first section addresses an X-ray spectrometric system designed to study radiological beams and is devoted to the optimization of diagnostic procedures in medicine. A parametric semi-empirical model capable of efficiently reconstructing diagnostic X-ray spectra in 'middle power' computers was developed and tested. In addition, different silicon diode detectors were tested as real-time detectors in order to provide a real-time evaluation of the spectrum during diagnostic procedures. This project contributes to the field by presenting an improved simulation of a realistic X-ray beam emerging from a common X-ray tube with a complete and detailed spectrum that lends itself to further studies of added filtration, thus providing an optimized beam for different diagnostic applications in medicine. The second section describes the preliminary tests that have been carried out on the first version of an Application Specific Integrated Circuit (ASIC), integrated with large area position-sensitive Silicon Drift Detector (SDD) to be used on board future space missions. This technology has been developed for the ESA project: LOFT (Large Observatory for X-ray Timing), a new medium-class space mission that the European Space Agency has been assessing since February of 2011. The LOFT project was proposed as part of the Cosmic Vision Program (2015-2025).

Sviluppo di mezzi e sistemi di sorveglianza e monitoraggio dei ditteri culicidi di importanza sanitaria

Nel corso degli ultimi anni le problematiche legate al ruolo vettore delle zanzare stanno emergendo sia per quanto riguarda l’uomo che gli animali allevati e selvatici. Diversi arbovirus come West Nile, Chikungunya, Usutu e Dengue, possono facilmente spostarsi a livello planetario ed essere introdotti anche nei nostri territori dove possono dare avvio a episodi epidemici. Le tecniche di monitoraggio e sorveglianza dei Culicidi possono essere convenientemente utilizzate per il rilevamento precoce dell’attività virale sul territorio e per la stima del rischio di epidemie al fine dell’adozione delle opportune azioni di Sanità Pubblica. Io scopo della ricerca del dottorato è inserito nel contesto dei temi di sviluppo del Piano regionale sorveglianza delle malattie trasmesse da vettori in Emilia Romagna. La ricerca condotta è inquadrata prevalentemente sotto l’aspetto entomologico applicativo di utilizzo di dispositivi (trappole) che possano catturare efficacemente possibili insetti vettori. In particolare questa ricerca è stata mirata allo studio comparativo in campo di diversi tipi di trappole per la cattura di adulti di zanzara, cercando di interpretare i dati per capire un potenziale valore di efficacia/efficienza nel rilevamento della circolazione virale e come supporto alla pianificazione della rete di sorveglianza dal punto di vista operativo mediante dispositivi adeguati alle finalità d’indagine. Si è cercato di trovare un dispositivo idoneo, approfondendone gli aspetti operativi/funzionali, ai fini di cattura del vettore principale del West Nile Virus, cioè la zanzara comune, da affiancare all’unica tipologia di trappola usata in precedenza. Le prove saranno svolte sia in campo che presso il laboratorio di Entomologia Medica Veterinaria del Centro Agricoltura Ambiente “G. Nicoli” di Crevalcore, in collaborazione con il Dipartimento di Scienze e Tecnologie Agroambientali della Facoltà di Agraria dell’Università di Bologna.
