L’articolo offre la descrizione dei manoscritti petrarcheschi conservati presso la Biblioteca Reale di Torino, istituzione fondata da Carlo Alberto di Savoia nel 1831. Si tratta di sette testimoni ...contenenti opere di Francesco Petrarca, cinque dei quali quattrocenteschi (Varia 100, 104, 108, 132 e 269) e due settecenteschi (Vernazza 51.22 e 51.24), a cui sono stati aggiunti altri cinque documenti risalenti ai secoli XVIII-XX che contengono materiali petrarcheschi diversi (saggi critici sulle opere di Petrarca, riproduzioni di autografi e di epigrafi). The paper offers a description of Petrarch manuscripts kept at the Royal Library of Turin, an institution established by Charles Albert of Savoy in 1831. These are seven codices containing works by Francesco Petrarca, five of the XV century (Varia 100, 104, 108, 132 and 269) and two of the XVIII (Vernazza 51.22 and 51.24); in addition there are five other documents, dating back to the XVIII-XX centuries, containing materials about Petrarch (critical essays on his works, reproductions of autographs and epigraphs).
The Piemonte mountains surrounding the city of Torino comprise a wide variety of rocks, characterized by a multitude of minerals, structures and colors. The Alps, because of their long and complex ...history, have produced a wide variety of ornamental stone used in the town, over the centuries, for both esthetic and structural reasons. TOURinSTONES is an application for mobile phones that allows geotourists to walk in the center of Torino, where the visitor can find Alpine rocks used in palaces and historical monuments as witnesses and tangible symbols of the city. The application consists of 26 historical sites of interest in each of which ornamental stones of historical and scientific interest can be observed in detail. The sites are grouped in four thematic itineraries through which the user can discover the city from the cultural and architectural point of view. By a numbered list of the stones used in all the described monuments, the user can access specific data on each rock including quarry location, petrographic description and utilization in Torino. The mobile application can be downloaded free from the App Store or Google Play respectively for Apple and Android devices.
The study aimed to obtain optometric findings of amyotrophic lateral sclerosis (ALS) patients in different stages of the disease, and to determine the relation between ocular data and ALS-related ...features; that is, functional and cognitive impairment and staging.
The optometric protocol included tests of the ocular motility broad-H test and Northeastern State University College of Optometry (NSUCO) test, near point of convergence (NPC), error refraction, best-corrected visual acuity, and binocular visual alignment, and an ocular symptoms questionnaire. The functional measures included the Amyotrophic Lateral Sclerosis Functional Rating Scale-revised (ALSFRS-r) and Milano-Torino staging (MiToS), and cognitive impairment was assessed using the Edinburgh Cognitive and Behavioural ALS Screen (ECAS). Demographic and clinical features were also collected, including whether the patients used an eye-tracking communication device (ETCD).
Two-hundred consecutive ALS patients (median age of 64 years, 118 males and 82 females) in different stages of disease were recruited. Nearly 70% of patients reported at least one ocular symptom, and the use of an ETCD was found to be significantly related to the presence of most symptoms. Moreover, the severely symptomatic group was characterized by significantly lower ALSFRS-r total and subscale scores, and higher MiToS. Abnormal NPC values were significantly related to lower ALSFRS-r total and bulbar-subscale scores. Patients with acceptable NSUCO test values exhibited significantly higher ECAS scores.
The presence of ocular alteration in patients in different stages of ALS supports the idea that this is a multisystem disorder and emphasizes the importance of optometric evaluations in multidisciplinary assessments to address ocular impairment early in the disease process.
In this work, we show that various quantum interaction radial potential models used for describing diatomic molecules are particular cases of an exactly solvable multiparameter exponential-type ...potential. This feature is exploited to find the conditions that potentials should fulfill to be considered as equivalent. As an example of the usefulness of the proposal, the obtained requirements are applied to some of the most common diatomic potential models. Specifically, we have shown the equivalence among the radial potentials of Manning–Rosen, Deng–Fang, Schiöberg, Badawi–Bessis–Bessis, Tietz, Wie, Sun, the negative of the Williams–Poulios and the Möbius square potentials. The proposal to obtain equivalent radial potentials is general and can be directly applied to other interaction models as well as in the study of relativistic molecular physics.

, the main constituent of bones and teeth enamels, is a widely studied and employed biomaterial. Its applications span from dental to orthopedic implants, ...including bone tissue engineering scaffolds, coating, filler and many others. Previous theoretical and experimental studies have already characterized the physical–chemical foundations of water adsorption on a number of HA surfaces, an essential step in the mechanism of biomaterial integration. Here, we extend such knowledge by simulating, at a hybrid DFT level of theory, different HA surface terminations, both stoichiometric and non-stoichiometric, as free and in interaction with water. Such a goal is achieved at an unprecedented accuracy, with a large all-electron basis set and including dispersion forces contributions. The calculated results are then compared with experimental micro-calorimetric data, showing a good agreement in the loading trend of the (010) surfaces. More generally, this theoretical approach is confirmed to be an efficient tool to analyze these biomaterials, giving the possibility to investigate the HA behavior toward more complex molecules, from amino acids to collagen, at the here-presented level of theory, to shed some light on the complex biomineralization process of human bones and teeth.

John Shearman makes the plea for a more engaged reading of art works of the Italian Renaissance, one that will recognize the presuppositions of Renaissance artists about their viewers. His book is ...the first attempt to construct a history of those Renaissance paintings and sculptures that are by design completed outside themselves in or by the spectator, that embrace the spectator into their narrative plot or aesthetic functioning, and that reposition the spectator imaginatively or in time and space. He takes the lead from texts and artists of the period, for these artists reveal themselves as spectators. Among modern historiographical techniques, Reception Theory is closest to the author's method, but Shearman's concern is mostly with anterior relationships with the viewer--that is, relationships conceived and constructed as part of the work's design, making, and positioning. Shearman proposes unconventional ways in which works of art may be distinguished one from another, and in which spectators may be distinguished, too, and enlarges the accepted field of artistic invention. Furthermore, His argument reflects on the Renaissance itself. What is created in this period tends to be regarded as conventional, or inherent in the nature of painting and sculpture: he maintains that this is a careless, disengaged view that has overlooked the process of discovery by immensely inventive and visually intelllectual artists. John Shearman is William Door Boardman Professor of Fine Arts at Harvard University. Among his works areMannerism (Hardmondsworth/Penguin), Raphael's Cartoons in the Collection of Her Majesty the Queen and the Tapestries for the Sistine Chapel (Phaidon), The Early Italian Paintings in teh Collection of Her Majesty the Queen (Cambridge). and Funzione e Illusione (il Saggiatore).

Viene presentata un’analisi della popolazione di Cicogna bianca (Ciconia ciconia) in Piemonte nord occidentale e, specificatamente, in provincia di Torino negli ultimi 20 anni. Il primo tentativo di ...nidificazione risale al 1980, ma è solo a partire dal 1996 che si è registrata una colonizzazione del territorio torinese con la presenza di un massimo di 8 coppie (2014). Parallelamente, anche il numero di individui svernanti nella stessa area, particolarmente in prossimità di discariche di rifiuti urbani, è aumentato. Viene indicata una correlazione tra l’aumento del numero di individui non migranti e il numero di coppie nidificanti nella stessa area.
The electronic structure of the neutral vacancy in diamond is investigated by using a periodic approach (supercells containing 32, 64 and 128 atoms have been considered), the Hartree–Fock (HF), pure ...DFT (LDA, PBE), global (B3LYP and PBE0) and range-separated (HSE06) “hybrid” functionals, and a local basis set as implemented in the CRYSTAL14 code. LDA and GGA provide metallic solutions for the three possible spin states (characterized by
S
z

,

,

), whereas hybrids and HF, thanks to the “exact” exchange, which plays such a crucial role in the present case, provide well-localized defect states in the band gap of the insulating system. As a consequence of the metallic solution, for the
S

and 1 states, the spin polarization tends to disappear when pure DFT is used, while with HF and hybrids the uncoupled electrons remain strongly localized on the first nearest neighbors, as documented by the spin density maps. The relative stability between the three spin states is

. The defect crystalline orbitals are classified by symmetry and identified in the band structure with respect to the valence and conducting electrons. The formation energy of the vacancy, evaluated with six different functionals, is close to 7 eV for three of them (7.00 HSE06, 7.05 LDA, 7.11 PBE0), slightly smaller in B3LYP (6.74) and PBE (6.56). Cluster calculations (

In the literature, several vulnerability/resilience indicators and indexes are based and assessed by taking into account and combining different dimensions. Housing vulnerability is one of these ...dimensions and is strictly related to the buildings’ physical features and to the socio-economic condition of their occupants. This research aims to study housing vulnerability in relation to the real estate market by identifying possible indicators and spatially analyzing their influence on property prices. Assuming the city of Turin and its territorial segmentation as a case study, spatial analyses were performed to take into account the presence of spatial dependence and to identify the variables that significantly influence the process of property price determination. The results of this study highlighted the fact that two housing vulnerability indicators, representative of fragile buildings’ physical features, were spatially correlated with property prices and had a significant and negative influence on them. In addition, their comparison with two social vulnerability indicators demonstrated that the presence of economical buildings and council houses was spatially correlated with the presence of people with a low education level. The results of the spatial regression model also confirmed that one of the social vulnerability indicators had the highest and most negative explanatory power in the property price determination process.
