EXCITE - A 12U Cubesat Mission for IOD/IOV
No full textEXCITE (“EXtended Cubesat for Innovative Technology Experiments”) is a technology demonstration mission selected by ASI in 2021 in the frame of the "Future Cubesat Missions" call. Based on a custom-designed 12U CubeSat platform featuring a full-composite structure, EXCITE is aimed at in-orbit demonstration / in-orbit validation of a number of innovative small spacecraft technologies in the domains of chemical and electric onboard propulsion, thermal management of significant heat loads in limited volumes, COTS GPU computing for IoT applications, and steerable, integrated S-band antennas. In this paper we describe the EXCITE platform design, outline the mission profile and discuss the main expected technological innovations
Eczema allergico da contatto (DAC) nel personale sanitario. Quali apteni sono maggiormente responsabili della sensibilizzazione?
No full textABSTRACT
In the last decades, the enhanced use of rubber gloves caused an increase of allergic dermatitis among health workers. The aim of our study was of finding out the most common sensitizing agents causing the diseases. We found that the accelerators are most often implicated. We recommend a panel of substances to be tested by patch test in skin symptomatic workers, in particular, carbamates, thiurams and metals

The genetic susceptibility in the development of malignant pleural mesothelioma
No full textMalignant pleural mesothelioma (MPM) is a cancer of the pleural cavity whose main risk factor is exposure to asbestos. However, it has been shown that only a minority of exposed people develops MPM. In fact, the incidence among professionally exposed workers was shown to vary between 0.5% and 18.0%. Various hints suggested that other important cofactors could play a role, in particular the genetic susceptibility. Impressive is the case of Cappadocians families exposed to erionite and affected by an "epidemic" of MPM with about half of the inhabitants dying for the disease. However, no results for a "Cappadocia" gene of susceptibility to MPM have been obtained yet and more studies are needed. Among asbestos-exposed workers, several studies reported familial cases of MPM, suggesting that heredity could be important in the tumor development. However, large studies on familial clusters showed only weak increased risks that could be attributable also to indirect exposures in a contaminated household. Moreover, the risk of developing MPM is increased of a limited extent among people exposed to asbestos with a positive history of familial cancers. A particular is represented by carriers of germline mutations within BAP1 gene. In families and in animal models, mutations within BAP1 are strongly predisposing to develop MPM. However, also other types of cancer (such as uveal melanoma) are present, thus BAP1 mutations are considered as responsible for a hereditary form of a multi-cancer syndrome. In any case, among sporadic MPM, the prevalence of germline BAP1 mutations is negligible. Finally, genetic studies highlighted the presence of low-risk susceptibility alleles, such as those within XRCC3, NAT2 or GSTM1. Two different genome-wide association studies could not find positive associations reaching the genome-wide statistical significance threshold, however, both were concordant in showing a weak signal within the SDK1 gene region. Overall, it could be concluded that, as for other types of sporadic cancers, the susceptibility to develop MPM following asbestos exposure is modulated moderately by the individual genetic background. Further studies on larger series could help in a better characterization of more genes predisposing to MPM, being this tumor a rare disease
Science, Technology and Systems Engineering Educational Activities with Stratospheric Balloons
No full textThe Space Systems Laboratory of the University of Pisa started in 2021 a student-oriented high altitude ballooning programme intended to provide an opportunity for hands-on experience in support of scientific and technical courses. Following a call for proposal open to all students across all study areas, three experiments were selected featuring multi-disciplinary teams. The programme provides mentoring on scientific, technical and management issues, financial support and assistance with integration and launch on a sounding balloon platform. The goal is to fly the experiments in the stratosphere, retrieve them after landing and process the results; by doing so, the students experience all phases of a scientific mission project, from conceptual design to realization, operations and post-flight analysis. This paper summarizes the features of the programme’s first edition
QR-factorization of Displacement Structured Matrices Using a Rank Structured Matrix Approach
No full textPerceptually Visible but Emotionally Subliminal Stimuli to Improve Exposure Therapies
No full textSubliminal stimuli are gaining growing interest due to their capability to induce desensitization to pathologically feared (e.g., phobic) pictures without inducing exaggerated emotional reactions. However, unresolved methodological issues cast significant doubt on the reliability of these findings and their interpretation. The studies most robustly assessing stimulus detection found that ~30% of the supposed‐to‐be‐subliminal stimuli were, in fact, detected, suggesting that the beneficial effects attributed to subliminal stimuli may result from those actually seen. Nevertheless, a deeper analysis of the data underlying this misinterpretation unveils theoretical and clinical implications. Since the purpose of subliminal stimulation is to reduce the aversiveness of exposure therapies while maintaining their efficacy, researchers should measure the emotional relevance of supposed‐to‐be‐subliminal stimuli that are, in fact, detected. A distinction is needed between perceptually‐ and emotionally‐subliminal stimuli: the former is not consciously detected; the latter just fails to elicit emotional reactions. Emotionally‐subliminal stimuli could represent an intermediate step of exposure in addition to those involving perceptually subliminal or supraliminal stimuli. Importantly, emotionally subliminal stimuli could make patients able to sustain a conscious exposure to feared stimuli without exaggeratedly reacting to them: if confirmed by empirical data, this unexpected disconfirmation of patients’ beliefs could pave the way for successful therapy while increasing their self‐efficacy and compliance to treatment
