Descriptive analysis and evaluation of the components of the quarter
No full textCapitolo che si riferisce all’individuazione dei nodi, dei percorsi, dei riferimenti, dei margini (con riferimento ai principi introdotti da K. Lynch), del quartiere Greco- Ortodosso dell'Annunciazione a Nazareth (Is) e alla loro valutazione secondo gli indicatori di qualità/degrado, livello di conoscenza a scala locale, nazionale e mondiale, livello di accessibilità, livello di visibilità e livello di leggibilità (ispirandosi ai principi del Codice dei Beni Culturali italiano -D.Lgs. 42/2004).
In questa fase si è proceduto anche al rilievo ed alla restituzione grafica (L. Astegno), al rilievo dello stato di degrado (L. Astegno, M. Merlo) e alla lettura iconografica delle opere interne (M. Boscolo Marchi) della settecentesca Chiesa Ortodossa dell’Annunciazione che contiene, secondo la tradizione, il Pozzo di Maria
The formation volume in rare earth intermetallic systems: A representation by means of atomic physical quantities
No full textThe formation of the intermetallic phases is often accompanied by large volume effects, and several interpretations of this phenomenon have been proposed following different approaches, either from a simply empirical or purely theoretical point of view. In his pioneering work, Biltz (Biltz 1934) employed the experimental density values to list the molar volumes of the elements and of numerous inorganic and organic solids, including intermetallic phases. The systematic analysis of the data allowed the scientist to estimate the effective volumes of the atoms within the compounds, making possible the application of the volume additivity. Machlin studied the effects of electronegativity on energy and volume of formation, assuming that the volume corrections depend on the Gordy electronegativity difference (Machlin 1980). Watson and Bennett obtained 82a good correlation between the volume effects shown by the phases of the transition elements and a scale resembling the Gordy electronegativity, while a cellular method was applied to estimate the volume changes in phases with alkaline and alkaline earth metals (Watson and Bennett 1982, 1984). Alonso showed that a model of a disordered binary alloy of nontransition metals explains the tendency to a negative deviation from Vegard’s law as this lowers the energy of formation (Alonso et al. 1984). In the Miedema model (Miedema and Niessen 1982), the volume contraction in metallic systems can be ascribed to a charge transfer effect, described mainly by the differences both in an electronegativity-like scale (F*) and in the electron density parameter (nWS). Moreover, in systems with atoms of different radius, a further volume contraction may arise from elastic size mismatch energy. The differences in electronegativity are ignored in the Hafner approach, based on the lowest-order pseudopotential perturbation theory (Hafner 1985). This method provides good results for extended solid solutions of homovalent systems (intra-alkaline and intra-alkaline-earth alloys) and for some intermetallics of the cited elements. A phenomenological approach was used to describe the volume effects displayed by the intermetallic compounds formed by alkaline earths (Ca, Sr, Ba) and divalent rare earths (Eu, Yb) (Merlo 1988) and by the trivalent rare earths (Merlo and Fornasini 1993), introducing a charge transfer atomic parameter, correlated with Pauling’s electronegativity. More recently, the volume contractions of the binary phases of Ca, Sr, Ba, Eu and Yb were represented by a simple equation containing the electronegativity, the compressibility and the group number (Fornasini and Merlo 2006). The most advanced method is based on the calculation of partial atomic volumes and charges as a function of composition (Baranov et al. 2007)

Representations and narratives of F to M Gender Dysphoric subjects: Self, Body and psycho-traumatology in comparison with M to F transsexualism
No full textThe present study was aimed at extending the method previously used with M to F gender dysphoric patients, to F to M individuals. In particular, the aim of the study was to highlight global and particular representations of the subjects. The study involved 10 gender dysphoric subjects in F to M transition, aged between 18 to 26 years old. Rorschach and the Thematic Apperception Test were administered with particular attention to the detection of psycho-traumatic indexes. The data reached through the extension of the method to F to M subjects revealed a continuity between the two groups. Referring to Self-representation, the subjects produced mainly objectual responses, indicative of a global representation affected by the current physical condition. In terms of Body representation, the subjects provided answers demonstrating the presence of partiality and fragmentation, indicative of a body representation supporting the term dysphoria. Approximately 30% of the subjects\u27 responses indicated the presence of consistent psycho-traumatology. In comparative terms, F to M subjects provided quantitatively and quantitatively similar answers to M to F subjects, with a greater number of fragmentary responses and a lower presence of psycho-traumatic indexes
Unconditional M-quantile regression
No full textIn this paper we develop the unconditional M-quantile regression for modeling unconditional M-quantiles in the presence of covariates. Extending the paper by Firpo et al. (2009), we assess the impact of small changes in the explanatory variables on the M-quantile of the unconditional distribution of the dependent variable by running a mean regression of the recentered influence function of the unconditional M-quantile on the covariates. The proposed methodology is applied on the Survey of Household Income and Wealth (SHIW) 2016 conducted by the Bank of Italy

p73 is regulated by phosphorylation at the G2/M transition
No full textp73 is a p53 paralog that encodes proapoptotic (transactivation-competent (TA)) and antiapoptotic ( dominant negative) isoforms. TAp73 transcription factors mediate cell cycle arrest and/or apoptosis in response to DNA damage and are involved in developmental processes in the central nervous system and the immune system. p73 proteins may also play a role in the regulation of cell growth. Indeed, p73 expression is itself modulated during the cell cycle and TAp73 proteins accumulate in S phase cells. In addition, the function of p73 proteins is also regulated by post-translational modifications and protein-protein interactions in different cellular and pathophysiological contexts. Here we show that p73 is a physiological target of the p34(cdc2)-cyclin B mitotic kinase complex in vivo. Both p73beta and p73alpha isoforms are hyperphosphorylated in normal mitotic cells and during mitotic arrest induced by microtubule-targeting drugs. p34(cdc2)-cyclin B phosphorylates and associates with p73 in vivo, which results in a decreased ability of p73 to both bind DNA and activate transcription in mitotic cells. Indeed, p73 is excluded from condensed chromosomes in meta- and anaphase, redistributes throughout the mitotic cytoplasm, and unlike p53, shows no association with centrosomes. Together these results indicate that M phase-specific phosphorylation of p73 by p34(cdc2)- cyclin B is associated with negative regulation of its transcriptional activating function
Directional M-quantile regression for multivariate dependent outcomes
No full textIn the present work we generalize the univariate M-quantile regression to the analysis of multivariate dependent outcomes. Extending the notion of directional quantiles, we introduce directional M-quantiles which are obtained as projections of the original data on a specified unit norm direction. In order to take into consideration the correlation within grouped measurements and to increase efficiency, we develop a marginal M-Quantile regression model extending the well known generalized estimating equations approach. We build M-quantile regions and contours which allow us to investigate the effect of the covariates on the location, spread and shape of the distribution of the responses. To identify potential outliers and provide a simple visual representation of the variability of the M quantile contours estimator, we construct confidence envelope via nonparametric bootstrap. The validity of our method is analyzed through the study of the wages data from the National Longitudinal Survey of Youth
