Congenital mitral regurgitation caused by a perforation in the anterior leaflet: Perioperative evaluation by color-coded Doppler echocardiography
1990
Color-coded two-dimensional (2D) echocardiography confirmed the presence of severe congenital mitral regurgitation in an 8-month-old infant. Intraoperative inspection revealed an isolated perforation in the anterior leaflet.
Perioperative and periprocedural airway management and respiratory safety for the obese patient: 2016 SIAARTI Consensus.
2016
Proper management of obese patients requires a team vision and appropriate behaviors by all health care providers in hospital. Specialist competencies are fundamental, as are specific clinical pathways and good clinical practices designed to deal with patients whose Body Mass Index (BMI) is ≥30 kg/m2. Standards of care for bariatric and non-bariatric surgery and for the critical care management of this population exist but are not well defined nor clearly followed in every hospital. Thus every anesthesiologist is likely to deal with this challenging population. Obesity is a multisystem, chronic, proinflammatory disorder. Unfortunately many countries are facing a marked increase in the obese…
Between leader-worship and member’s democracy: The consumer co-operatives in the fascist Italy
2018
En este artículo se analiza el impacto del régimen fascista italiano en el movimiento cooperativista de consumo, tema de interés ya que supone un choque entre una cultura política antidemocrática y una cultura económica democrática. Se intenta demostrar que el régimen fascista penalizó al movimiento cooperativista de consumo de varias formas. Sin embargo, un reducido número de organizaciones constituyeron una excepción a este fenómeno y, paradójicamente, tuvieron un considerable éxito en su funcionamiento desde el punto de vista empresarial. Algunos problemas —tamaño reducido, excesiva inversión social, una visión más política que empresarial— fueron resueltos de manera frecuente por los nu…
Biological and physico-chemical properties of new root canal sealers
2018
Background The purpose of the present study was to compare the biological and the physico-chemical properties of bioceramic-based root canal sealers, calcium hydroxide-based, MTA-based and epoxy resin-based root canal sealers. Material and methods Two bioceramic-based sealers, one calcium hydroxide-based sealer, one MTA-based sealer and two epoxy resin-based sealers were tested. Results EasySeal and MTA Fillapex showed severe citotoxic activity, AH Plus and SealapexTM moderate cytotoxicity, BioRoot™ RCS and TotalFill BC Sealer were both cytocompatible. Except for TotalFill BC Sealer, all root canal sealers caused inhibition zones when tested with E. faecalis. The highest inhibition zone was…
KEY FACTORS FOR SUCCESS IN AGRIFOOD FIRMS: THE CASE OF SPANISH FRUIT & VEGETABLES COOPERATIVES
2015
El tamaño es una variable contingente que puede influir en los resultados de las empresas. En este trabajo se pretende contrastar la existencia o no de una relación significativa entre tamaño y resultados empresariales de las empresas agrarias, en particular de las cooperativas hortofrutícolas españolas. Para ello, se realiza un estudio empírico en base a la información económica y financiera obtenida de los registros oficiales de las cooperativas agrarias dedicadas a la comercialización de frutas y hortalizas sobre el cual se ha aplicado un análisis de regresión. El estudio demuestra que no existe una relación significativa positiva entre los resultados empresariales y el tamaño de este ti…

Mammographic images segmentation based on chaotic map clustering algorithm
2013
Background: This work investigates the applicability of a novel clustering approach to the segmentation of mammographic digital images. The chaotic map clustering algorithm is used to group together similar subsets of image pixels resulting in a medically meaningful partition of the mammography. Methods: The image is divided into pixels subsets characterized by a set of conveniently chosen features and each of the corresponding points in the feature space is associated to a map. A mutual coupling strength between the maps depending on the associated distance between feature space points is subsequently introduced. On the system of maps, the simulated evolution through chaotic dynamics leads…
Le cooperative di comunità quali potenziale strumento per ripensare e valorizzare gli usi civici nelle aree rurali. Uno spunto di riflessione
2020
Regolate da frammentate normative regionali, le cooperative di comunità si caratterizzano per inserirsi pienamente nel quadro delineato agli artt. 2511 c.c. ss. e per la tendenziale coincidenza tra i soci di queste ultime e la popolazione insistente in un’area geograficamente limitata. La presenza di gruppi organizzati di individui che svolgono attività di valorizzazione dei territori può rivelarsi potenzialmente capace di stimolare l’attività economica locale e perseguire lo sviluppo comunitario e il benessere collettivo, in un’ottica di relazione sinergica tra interessi pubblici e privati. L’importanza di una dimensione intergenerazionale, tipica dello sviluppo sostenibile e particola…
Enhancement of the Lifetime of Metastable States in Er-Doped Si Nanocrystals by External Colored Noise
2015
The changes in the lifetime of a metastable energy level in Er-doped Si nanocrystals in the presence of an external source of colored noise are analyzed for different values of noise intensity and correlation time. Exciton dynamics is simulated by a set of phenomenological rate equations which take into account all the possible phenomena inherent in the energy states of Si nanocrystals and Er^{3+} ions in the host material of Si oxide. Electronic deexcitation is studied by examining the decay of the initial population of the Er atoms in the first excitation level 4I_{13/2} through fluorescence and cooperative energy transfer upconversion. Our results show that the deexcitation process of th…
On robustness and dynamics in (un)balanced coalitional games
2012
In this paper we investigate robustness and dynamics for coalitional games with transferable utilities (TU games). In particular we study sequences of TU games. These sequences model dynamic situations in which the values of coalitions of players are not known beforehand, and are subject to changes over time. An allocation rule assigns a payoff to each player in each time period. This payoff is bounded by external restrictions, for example due to contractual agreements. Our main questions are: (i) under which conditions do the allocations converge to a core-element of the game, and (ii) when do the allocations converge to some specific allocation, the so-called nominal allocation? The main …
