Leishmaniasis mucocutánea labial, las apariencias pueden engañar.
2019
espanolLa leishmaniasis es una infeccion endemica en nuestro medio. Dentro de sus presentaciones, la forma mucocutanea es la menos frecuente. A pesar de ello se ha de tener en cuenta incluso en casos clinicamente sugestivos de patologia tumoral, como el que presentamos. EnglishLeishmaniasis is an endemic disease in the mediterranean region. Although mucocutaneous presentation is not frequent, we should considerate it in the differential diagnosis of tumoral pathology.
Plurilinguismo versus monolinguismo: il sistema variantistico di 'Horcynus Orca'
2014
Il saggio indaga lo stile e la lingua, la architettura compositiva di Horcynus Orca di Stefano D’Arrigo e ne analizza il processo variantistico nelle diverse fasi redazionali. Ne risulta un procedimento finalizzato alla resa di un linguaggio corale, di un impasto di voci che caratterizzano l’opera come epos annullandone la plurivocità romanzesca.
Fick Diffusion Coefficients in Ternary Liquid Systems from Equilibrium Molecular Dynamics Simulations
2012
An approach for computing Fick diffusivities directly from equilibrium molecular dynamics (MD) simulations is presented and demonstrated for a ternary chloroform–acetone–methanol liquid mixture. In our approach, Fick diffusivities are calculated from the Maxwell–Stefan (MS) diffusivities and the so-called matrix of thermodynamic factors. MS diffusivities describe the friction between different molecular species and can be directly computed from MD simulations. The thermodynamic factor describes the deviation from ideal mixing behavior and is difficult to extract from both experiments and simulations. Here, we show that the thermodynamic factor in ternary systems can be obtained from density…
Waterfront urbani: Palermo. Analisi, interventi, piani e progetti
2010
L'articolo ha per oggetto l'analisi e lo studio del tratto di territorio costiero che si sviluppa lineramente da Acqua dei Corsari e Vergine Maria, e che rappresenta nel complesso, il waterfront di Palermo; lo scritto passa in rassegna le trasformazioni più evidenti che hanno interessato la costa della città sin dai tempi antichi, i piani e i progetti realizzati e quelli realizzati negli ultimi anni.
Nutritional supplements for neuropsychiatric symptoms in people with dementia: A systematic review and meta-analysis
2020
The aim of the present study was to assess the effects of nutritional supplementation on neuropsychiatric symptoms among people with dementia. Methods/Design: Randomized controlled trials (RCTs) were searched in the Databases PubMed, EMBASE, SCOPUS, Cochrane Central Register of Controlled Trials and Clinicaltrials.gov from inception until January 31, 2020. Studies of RCTs carried out on people with any type of dementia who were taking nutritional supplements and had neuropsychiatric symptoms were included in this systematic review and meta-analysis. Neuropsychiatric symptoms were assessed with the validated Neuropsychiatric Inventory (NPI). Effect sizes were calculated with standardized mea…
Il riconoscimento reciproco del maschile e del femminile nella prospettiva della pedagogia fondamentale
2017
Il saggio descrive i dati fenomenologici elementari delle identità dei generi, la genitalità anatomica e il gender. Questo secondo reperto si presenta come l’aspetto malleabile della sessualità umana; la variabilità non è però assoluta: il corpo non può essere annullato e con esso le proprietà del corpo femminile e di quello maschile, congegni atti a generare una nuova vita della specie umana. Questi rilievi sono visti nella prospettiva dell’azione educativa, qui intesa come relazionalità riconoscente. Ora, una tale prospettiva consente di definire le identità dei generi come un’esistenziale, intenzionalità situata e desituante legate da un’unità originaria che ha la sua condizione di possi…
Estimation of the Repeatedly-Projected Reduced Density Matrix under Decoherence
2007
Decoherence is believed to deteriorate the ability of a purification scheme that is based on the idea of driving a system to a pure state by repeatedly measuring another system in interaction with the former and hinder for a pure state to be extracted asymptotically. Nevertheless, we find a way out of this difficulty by deriving an analytic expression of the reduced density matrix for a two-qubit system immersed in a bath. It is shown that we can still extract a pure state if the environment brings about only dephasing effects. In addition, for a dissipative environment, there is a possibility of obtaining a dominant pure state when we perform a finite number of measurements.
Existence and Uniqueness Results for Quasi-linear Elliptic and Parabolic Equations with Nonlinear Boundary Conditions
2006
We study the questions of existence and uniqueness of weak and entropy solutions for equations of type -div a(x, Du)+γ(u) ∋ φ, posed in an open bounded subset Ω of ℝN, with nonlinear boundary conditions of the form a(x, Du)·η+β(u) ∋ ψ. The nonlinear elliptic operator div a(x, Du) is modeled on the p-Laplacian operator Δp(u) = div (|Du|p−2Du), with p > 1, γ and β are maximal monotone graphs in ℝ2 such that 0 ∈ γ(0) and 0 ∈ β(0), and the data φ ∈ L1 (Ω) and ψ ∈ L1 (∂Ω). We also study existence and uniqueness of weak solutions for a general degenerate elliptic-parabolic problem with nonlinear dynamical boundary conditions. Particular instances of this problem appear in various phenomena with c…
Analytical Expressions for Radiative Losses in Solar Cells
2019
Analytical expressions for the fundamental losses in single junction solar cells are revised and improved. The losses are, as far as possible, described using parameters with clear physical interpretations. One important improvement compared to earlier work is the use of Lambert’s W function, which allows for analytical expressions for the voltage and current at the maximum power point. Other improvements include the use of Stefan Boltzmann’s law to describe the incoming energy flux as well as taking into account the fermionic nature of the electrons when calculating the thermalization loss. A new expression, which combines emission, Boltzmann and Carnot losses, is presented. Finally, an ex…
Heat transfer in conducting and radiating bodies
1997
Abstract We introduce briefly some nonlocal models for heat transfer in conducting and radiating media. The goal is to give an idea of the general mathematical structure and related existence results for such models.
