Reptiles in the diet of a Oncorhynchus mykiss (Osteichthyes: Salmonidae) naturalized population in Piedmont (N Italy)
Franco Bernini,Alessandro Candiotto,Pietro Angelo Nardi,Simone Rossi
Acta Herpetologica , 2006,
Abstract: The authors report on predation by salmonid fish on some reptile species in two tributaries of the Tanaro river in the Alessandria province (NW Italy). The remains of Podarcis muralis, Anguis fragilis and of an undetermined colubrid of the genus Natrix were found in bromatological analyses performed on 117 Oncorhynchus mykiss specimens. Salmonid predation on herpetofauna once again confirms the alimentary opportunism of these fishes; however, predation is an occasional phenomenon and not a threat to the local reptile populations.
La difícil y necesaria integración entre la atención básica y la salud mental en Brasil
Magda Dimenstein,Rosane Neves,Simone Paulon,Henrique Nardi
Psicología desde el Caribe , 2010,
Abstract: El objetivo de este trabajo fue analizar la integración de las Estrategias de Salud de la Familia, uno de los pilares de la atención básica brasile a, con las políticas de salud mental en dos unidades de salud, una localizada en la ciudad de Porto Alegre, la otra en la ciudad de Natal. Para este fin fueron realizadas entrevistas y grupos focales con los integrantes de ambos equipos de salud y, posteriormente, se implementó un proceso de formación, articulado a la propuesta de Educación Permanente en Salud. En el análisis de la información obtenida, pudo observarse que entre los integrantes de los equipos de salud de ambas unidades prevalecen dos estrategias terapéuticas frente a casos entendidos como de salud mental: la prescripción de medicación psiquiátrica y la derivación a especialistas. Las formas de funcionamiento burocratizadas de los equipos de salud dificultan la implementación de otro tipo de estrategias e intervenciones.

Abstract: Localized scleroderma is a rare disease, characterized by sclerotic lesions. A variety of presentations have been described, with different clinical characteristics and specific prognosis. In scleroderma en coup de sabre (LScs) the atrophic lesion in frontoparietal area is the disease hallmark. Skin and subcutaneous are the mainly affected tissues, but case reports of muscle, cartilage, and bone involvement are frequent. These cases pose a difficult differential diagnosis with Parry-Romberg syndrome. Once considered an exclusive cutaneous disorder, the neurologic involvement present in LScs has been described in several case reports. Seizures are most frequently observed, but focal neurologic deficits, movement disorders, trigeminal neuralgia, and mimics of hemiplegic migraines have been reported. Computed tomography and magnetic resonance imaging have aided the characterization of central nervous system lesions, and cerebral angiograms have pointed to vasculitis as a part of disease pathogenesis. In this paper we describe the clinical and radiologic aspects of neurologic involvement in LScs. 1. Introduction Scleroderma is a rare disease of unknown etiology, characterized by thickening and hardening of skin resulting from increased collagen production. The term includes a variety of diseases, from localized scleroderma (LS) to systemic sclerosis. LS is traditionally considered to be limited to skin, subcutaneous tissue, underlying bone, and, in craniofacial subtype, nervous system involvement [1]. Recent studies, however, have described malaise, fatigue, arthralgia, and myalgia in morphea. Moreover, rheumatologic, ophthalmologic and neurologic symptoms and signs have been described in up to 20% of the patients with LS. Based on these findings LS ought to be differentiated from systemic sclerosis by the absence of sclerodactylya, Raynaud’s phenomenon, and capillaroscopic abnormalities [1]. LS incidence ranges from 0.4 to 2.7 per 100,000 people [2]. Although present in all races, the prevalence among Caucasians is increased, summing up 72 to 82% of the patients [2]. Females are primarily affected [1], and a similar distribution between children and adults occurs [1, 3]. Disease incidence peaks in the fifth decade of life in adults, whereas 90% of children are diagnosed between 2 and 14 years of age [1, 3–5]. Linear scleroderma en coup de sabre (LCsc) is a rare subset of LS. The typical presentation affects frontoparietal region, and the mean age of onset is around 13 years old [1]. In this paper, clinical presentation of LScs and its neurological
Topics in Leptogenesis
Nardi, Enrico
High Energy Physics - Phenomenology , 2007, DOI: 10.1063/1.2751943
Abstract: Baryogenesis via leptogenesis provides an appealing mechanism to explain the observed baryon asymmetry of the Universe. Recent refinements in the understanding of the dynamics of leptogenesis include detailed studies of the effects of lepton flavors and of the role possibly played by the lepton asymmetries generated in the decays of the heavier singlet neutrinos $N_{2,3}$. In this talk I present a short review of these recent developments in the theory of leptogenesis.

La depresión adolescente
Bernardo Nardi
Psicoperspectivas : Individuo y Sociedad , 2008,
Abstract: Este artículo trata principalmente de la depresión adolescente, en sus diversas expresiones en las diferentes Organizaciones de Significado Personal (OSP): Trastornos alimenticios psicógenos (DAP), Fóbicas (FOB), Obsesiva (OBS) y Depresiva (DEP). Se revisan las diferentes sintomatologías que adquiere la depresión adolescente en las diferentes organizaciones, como también el diagnóstico, y las modalidades de intervención. Así mismo, el autor se focaliza en la explicación post racionalista de este período del ciclo vital del trastorno y su sintomatología, más que en la descripción sintomática de la misma, enfatizando más el proceso que en la indagación sobre las causas. El autor desarrolla un modelo de intervención del tipo procesal sistémico para abordar los diferentes aspectos psicoterapéuticos.
Rol de los procesos filogenéticos y ontogenéticos en el desarrollo de las organizaciones de significado personal
Bernardo Nardi
Psicoperspectivas : Individuo y Sociedad , 2008,
Abstract: En el estudio del desarrollo de las organizaciones de significado personal (OSP) dos preguntas asumen una particular importancia: cuáles son los factores concurrentes invariantes que determinan el cierre organizacional específico típico de cada OSP? y cuál es el significado adaptativo que ha llevado a la aparición y a la mantención de las OSP, desde los orígenes de la humanidad hasta hoy y en la historia personal de cada sujeto? Han sido identificados tres aspectos fundamentales: 1) regulación de la distancia (eje protección-separación, arcaico, basado en una modalidad concreta de pensamiento) que lleva al emerger de las OSP FOB-Prone, centradas en el control de las condiciones de protección/libertad; y DEP-Prone, basadas en el manejo de la separación y de la autodeterminación; 2) atención hacia lo externo (eje baja-alta sintonización) que requiere modalidades abstractas de pensamiento y que está a la base de las OSP con enfoque interior DEP-Prone y FOB-Prone y de las OSP con enfoque exterior DAP-Prone y OBS-Prone; 3) coherencia comunicativa (eje comunicaciones indefinidas ambiguas-definidas ambivalentes) que requieren competencias abstractas y que lleva a tomar en cuenta ya sean los aspectos difuminados de la realidad en los desarrollos DAP-Prone o aquellos antitéticos en los desarrollos OBS-Prone.
Memories of science education in Brazil: the physics education research
Roberto Nardi
Investiga??es em Ensino de Ciências , 2005,
Abstract: Recordings made in the last few decades, like as papers, congresses proceedings, research groups reports and interviews recently taken among researchers, allowed to rescue some details of the path drawn by the Physics Education research in Brazil. The interpretation of certain sense effects conferred by the interviewees and other in the recordings analyzed, allows us to perceive the plurality of this area of study, the diversity of factors considered important to its constitution and some characteristics of the research in this area.
Performing Electronic Dance Music: mimesis, reflexivity and the commodification of listening
NARDI, Carlo
Contemporanea : Revista de Comunica??o e Cultura , 2012,
Abstract: Recent changes in the economy of music have induced some musicians in the electronic ance scene to adapt their repertoire to concert performance. However, this conversion is far from being unproblematic, as electronic dance music, being based on additive operations, programming and merging of roles, resists, to an extent, live performance. I will then examine some of the strategies that musicians adopt in order to bring into the performance an element of actuality, focusing on the sensorial implications of this process. The stage concert, however, challenges not only the modes of production, but also the ideology of club culture, which is based on participation and inclusiveness. Mimesis, as a means to establish contact with the audience through identification, allows overcoming the division drawn by the stage. On the other hand, reflexivity, as a way to acknowledge the different roles at play, counteracts the role of mimesis and restores the distinction between audience and performer, thus substantiating the condition that prompted this transformation and that entails, in the first place, the commodification of musical experience.
Signals of Unconventional E$_6$ Models at $e^+e^-$ Colliders
Enrico Nardi
Physics , 1993, DOI: 10.1103/PhysRevD.49.4394
Abstract: Generation dependent discrete symmetries often appear in models derived from superstring theories. In particular, in the framework of E$_6$ models the presence of such symmetries is required in order to allow for the radiative generation of naturally small neutrino masses. Recently it was shown that by imposing suitable generation dependent discrete symmetries, a class of models can be consistently constructed in which the three sets of known fermions in each generation do not have the same assignments with respect to the {\bf 27} representation of E$_6$. In this scenario, the different embedding in the gauge group of the three generations implies in particular that the known charged leptons couple in a non--universal way to the new neutral gauge bosons $(Z_\beta)$ present in these models. We exploit this fact to study the signature of this class of models at present and future $e^+e^-$ colliders. We show that some signals of deviation from lepton universality as well as some other discrepancies with the standard model predictions which have been observed at the TRISTAN collider in the production rate of $\mu$ and $\tau$, can be accounted for if the $Z_\beta$ mass is not much heavier than 300 GeV. We also study the discovery limits for lepton universality violation of this type at LEP-2 and at the 500 GeV $e^+e^-$ Next Linear Collider (NLC). We show that models predicting unconventional assignments for the leptons will give an unmistakable signature, when the $Z_\beta$ mass is as heavy as $\sim 800$ GeV (LEP-2) and $\sim 2$ TeV (NLC).
