No full textAntioxidants are an heterogeneous group of compounds able to counteract cell oxidation by acting as reducing agents, as free radical scavengers, and quenchers of radical species and other pro-oxidants, such as metals [...]
Some remarks on the symplectic and Kaehler geometry of toric varieties
No full textLet M be a projective toric manifold. We prove two results concerning, respectively, Kähler–Einstein submanifolds of M and symplectic embeddings of the standard Euclidean ball in M. Both results use the well-known fact that M contains an open dense subset biholomorphic to
A note on Kaehler--Einstein metrics and Bochner's coordinates
No full textIn this paper we prove that if a compact Kähler-Einstein manifold (M,ω) with integral Kähler form satisfies a compatibility condition between the domain of definition of the Bochner coordinates and of the diastasis potential, then c1(M) > 0
Third mission and espoused values of Italian universities: an investigation on official documents
No full textThis study examines the espoused values of Italian universities that emerge from statutes with the aim of eliciting patterns of representation of the third mission, which embraces all the activities by which universities contribute to the economic and social development of society. Since all statutes were updated between 2011 and 2012 because of a law enacted on 30 December 2010, n. 240, it is timely to use Italian universities to highlight current patterns of representation. Using a qualitative content analysis performed with Atlas.Ti (Muhr, 1994), seventy-five statutes were analyzed by focusing on core missions, functions attributed to the third-mission activities, and primary tasks of the organization vis-à-vis its environment. By relying on the systematic association between codes created to extrapolate the embodied meaning of the text and units of analysis, results have shown four organizational archetypes in the third mission: 1) Need for coherence, with an emphasis on the need to respect the functions of public institutions regarding the third-mission activities; 2) Exploitation, which focuses on patent disclosure; 3) Openness to participating in external change and satisfying external needs; and 4) Old School, with a focus on entrepreneurial activities as a source of funding. Our analysis leads to proposals for future research
Increasing complexity in structurally stable models: an application to a pure exchange economy
No full textA model M is defined (see Anderlini and Canning (2001) and Yu et al. (2009)) as a quadruple M = {Lambda, X, F, R}, where Lambda and X represent the parameter and actions spaces, respectively, F is a correspondence defining the feasible actions and R is a real-valued function which measures the degree of rationality of the feasible actions. We recall that structural stability means the continuity of the equilibrium set with respect to small perturbations of the parameters and that robustness to bounded rationality holds if small deviations from rationality imply small changes in the equilibrium set. In this paper we extend to a model (M) over bar = {(Lambda) over bar, (X) over bar, (F) over bar, (R) over bar}, where (Lambda) over bar is defined as the set of all compact subsets of A, (X) over bar = X, (F) over bar and (R) over bar are the feasibility and rationality correspondences which extend F and R, respectively. (M) over bar is more complex than M, since M is embedded into (M) over bar in a natural way. We show that the structural stability of A implies the structural stability of (M) over bar and that (M) over bar is robust to bounded rationality if (R) over bar is lower semi-continuous. This abstract characterization of complexity is important because it can be used to appraise the nontrivial issue of whether structural stability and robustness to bounded rationality are preserved when a structurally stable model M is extended to (M) over bar. By applying this abstract construction to a pure exchange economy, the result by Loi and Matta (2010), concerning the stability of the equilibrium set with respect to perturbations of endowments along a given path, is extended to perturbations of paths under bounded rationality.

The unforeseen during biotechnological therapy for moderate-to-severe psoriasis: How to manage pregnancy and breastfeeding, infections from Mycobacterium tuberculosis, hepatitis B virus, hepatitis C virus, and HIV, surgery, vaccinations, diagnosis of malignancy, and dose tapering
No full textThe use of biotechnological therapies for moderate-to-severe psoriasis is ever-expanding and it is becoming increasingly more frequent to encounter different unforeseen events during their use, such as fertile patients becoming pregnant and breastfeeding, development of infections due to personal habits like tuberculosis, hepatitis B virus, hepatitis C virus, or HIV, scheduling of surgical procedures, need of vaccinations, development of malignancy, and evaluation of dose tapering. As any clinician may experience at least one of these unexpected events, it should be good practice to know how to manage them. Thus, a practical analysis has been proposed in this study
La stratégie du SMTC en faveur de l'accessibilité des transports en commun aux personnes à mobilité réduite au regard de la loi du 11 février 2005
No full textLa loi du 11 février 2005 pour l'égalité des droits et des chances, la participation et la citoyenneté des personnes handicapées a instauré de nouvelles obligations aux autorités organisatrices de transports. Ces obligations sont, pour la première fois, assorties de mesures coercitives. Le Syndicat Mixte des Transports en Commun de l'agglomération grenobloise mène depuis le milieu des années 1980 une politique ambitieuse en faveur de l'accessibilité des transports en commun aux personnes à mobilité réduite : innovation mondiale du premier tramway à plancher bas en 1987, une première ligne de bus déclarée accessible en 1996. La concertation est la clé de voûte de cette dynamique. L'année 2006 marque un nouvel essor pour l'accessibilité des transports en commun de l'agglomération grenobloise par la formalisation d'un certain nombre d'outils et d'instances de concertation ou encore l'élaboration du PDU 2006-2012 de l'agglomération grenobloise qui contient désormais une annexe dédiée.transports en commun, accessibilité, PMR (Personnes à mobilité réduite), personnes handicapées, PDU (Plan de Déplacements Urbains), Grenoble (France)
A Laplace integral, the T-Y-Z expansion and Berezin's transform on a Kaehler manifold
No full textLet M be an n-dimensional complex manifold endowed with a C∞ Kähler metric g. We show that a certain Laplace-type integral Lm (x), when x varies in a sufficiently small open set U ⊂ M, has an asymptotic expansion Lm(x)= 1/mn ∑r≤0 m-rCr(f) (x), where Cr:C∞ (U) → C∞ (U) are smooth differential operators depending on the curvature of g and its covariant derivatives. As a consequence we furnish a different proof of Lu's theorem by computing the lower order terms of Tian-Yau-Zelditch expansion in terms of the operator Cj. Finally, we compute the differential operators Qj of the expansion Berm (f) = ∑r≤0 m-r Qr (f) of Berezin's transform in terms of the operators Cj
