Uno strumento di ausilio per alunni e insegnanti: il Sussidiario
Lâarticle a pour but dâillustrer les principes qui ont guidĂ© la conception et la rĂ©daction dâun manuel appelĂ© «sussidiario», dĂ©veloppĂ© par deux enseignantes de la VallĂ©e dâAoste dans le but de faciliter aux Ă©lĂšves immigrĂ©s lâaccĂšs aux contenus disciplinaires. Ayant frĂ©quentĂ© les cours dâalphabĂ©tisation en langue italienne, ces Ă©lĂšves nâont pas encore les compĂ©tences linguistiques nĂ©cessaires pour profiter des manuels scolaires utilisĂ©s en classe. Le «sussidiario» est donc un manuel multidisciplinaire, qui prĂ©sente une sĂ©lection des contenus fondamentaux de la premiĂšre annĂ©e du collĂšge. Ces contenus sont exposĂ©s par le biais de formes dâĂ©criture contrĂŽlĂ©e pour favoriser la rĂ©ception active et autonome des textes. En ce sens, le manuel est non seulement un outil pour aider lâacquisition des Ă©lĂšves non italophones, mais aussi une aide pour tous les Ă©lĂšves qui ont des difficultĂ©s Ă accĂ©der Ă la discipline Ă©tudiĂ©e. Il peut Ă©galement soutenir le travail des enseignants dans les classes multilingues et multiniveaux.The aim of this article is to illustrate the guidelines that governed the conception and realization of a textbook called «sussidiario», developed by two teachers in the Aosta Valley wishing to facilitate migrant pupilsâ access to the various subject matters. These pupils had learned a little Italian but do not as yet have the linguistic competences allowing them to benefit from the textbooks used in class. The «sussidiario» is a multidisciplinary manual that presents a selection of the basic knowledge acquired in the first year of secondary school. Contents are exposed thanks to forms of controlled writing that allow the texts to be used actively and independently. In this sense, the textbook is not only a help during the first stages of a foreign pupilâs schooling, it can also help all pupils who have difficulty accessing a given subject. It is also a help for the teacher confronted by multilingual and multilevel classrooms
Reflections on Covid19 nasopharingeal, faecal and peritoneal swabs in an infant with Wilms tumor: A case report
Proximal Sars-Cov-2 pandemic had radically changed the way surgeons work in many departments, forcing to reserve surgical treatment only for emergency and oncologic cases. We report a case of a ten months-old girl with right-sided Wilms tumor and a previous diagnosis of Sars-Cov-2 infection, who underwent open right nephrectomy. Surgery was planned after negativization of five nasopharyngeal tests, despite the simultaneous positivity of two rectal swabs. The procedure was performed safely with appropriate personal protective equipment (PPE). To better investigate viral excretion, the anesthetist repeated nasopharyngeal swab under general anesthesia, which resulted positive. At the same time, two peritoneal swabs were collected and showed the absence of the virus in the peritoneal fluid. This case highlights the importance of combining swabs from various sources to increase sensibility of the test. The value of nasopharyngeal swab under general anesthesia should be reinforced as it can result positive even after many negative tests. Very little is known abouttransmission of the virus through the peritoneum as both presence and absence of Sars-Cov-2 have been reported in the peritoneal fluid. Next literature will clarify which particular conditions determine viral penetration in this anatomical district
The Cu-CHA deNOx Catalyst in Action: Temperature-Dependent NH3-Assisted Selective Catalytic Reduction Monitored by Operando XAS and XES
Quantum information, cognition, and music
Parallelism represents an essential aspect of human mind/brain activities. One can recognize some common features between psychological parallelism and the characteristic parallel structures that arise in quantum theory and in quantum computation. The article is devoted to a discussion of the following questions: 1. a comparison between classical probabilistic Turing machines and quantum Turing machines. 2. possible applications of the quantum computational semantics to cognitive problems. 3. parallelism in music

A role for microbial selection in frescoes' deterioration in Tomba degli Scudi in Tarquinia, Italy
Mural paintings in the hypogeal environment of the Tomba degli Scudi in Tarquinia, Italy, show a quite
dramatic condition: the plaster mortar lost his cohesion and a white layer coating is spread over almost
all the wall surfaces. The aim of this research is to verify if the activity of microorganisms could be one of
the main causes of deterioration and if the adopted countermeasures (conventional biocide treatments)
are sufficient to stop it. A biocide treatment of the whole environment has been carried out before the
conservative intervention and the tomb has been closed for one month. When the tomb was opened
again, we sampled the microorganisms present on the frescoes and we identified four Bacillus species
and one mould survived to the biocide treatment. These organisms are able to produce spores, a highly
resistant biological form, which has permitted the survival despite the biocide treatment. We show
that these Bacillus strains are able to produce calcium carbonate and could be responsible for the white
deposition that was damaging and covering the entire surface of the frescoes. Our results confirm that
the sanitation intervention is non always resolutive and could even be deleterious in selecting harmful
microbial communities
Firstâprinciples Assessment of the Role of Water in the Reduction Half Cycle of LowâTemperature NH3âSCR over CuâCHA
Dispersion corrected density functional theory calculations show that the presence of H2O in the Reduction Half-Cycle (RHC) of NH3-SCR affects the free energy of the kinetically-relevant transition state (TS) leading to a reduction in the rate and activation energy with respect to dry conditions. In particular, H2O enthalpically stabilizes the kinetically-relevant TS by 20 kJ mol(-1) with respect to the dry counterpart. Such enthalpic stabilization vanishes when van der Waals (vdW) interactions are excluded from the calculations, thus showing the preeminent role of non-specific dispersion forces in the reduction of the activation enthalpy. At the same time, the enthalpic stabilization is more than compensated by the additional entropy losses of the TS brought forth by the presence of H2O in the CHA cage. Calculated enthalpy and entropy changes with respect to the dry case agree quantitatively with the experimental measurements and reflect the modified reacting environment in the presence of H2O. As a result, this study provides theoretical underpinnings on the mechanistic role of H2O in the RHC and, on a more general basis, highlights the importance of the molecular scale description of the reaction environment in voids of molecular dimensions
