Suppression of ferromagnetic order by Ag-doping: a neutron scattering investigation on Ce<sub>2</sub>(Pd<sub>1−<i>x</i> </sub>Ag<sub> <i>x</i> </sub>)<sub>2</sub>In (<i>x</i> = 0.20, 0.50)
No full textThe ground state magnetic behaviour of Ce2(Pd0.8Ag0.2)2In and Ce2(Pd0.5Ag0.5)2In, found in the ferromagnetic branch of Ce2Pd2In, has been investigated by neutron powder diffraction at low temperature. Ce2(Pd0.8Ag0.2)2In is characterized by a ferromagnetic structure with the Ce moments aligned along the c-axis and values of 0.96(2) μB. The compound retains the P4/mbm throughout the magnetic transition, although the magnetic ordering is accompanied by a significant decrease of the lattice strain along [0 0 l], suggesting a magnetostructural contribution. The magnetic behaviour of Ce2(Pd0.5Ag0.5)2In is very different; this compound exhibits an extremely reduced magnetic scattering contribution in the diffraction pattern, that can be ascribed to a different kind of ferromagnetic ordering, with extremely reduced magnetic moments (∼0.1 μB) aligned along [0 l 0]. These results point to a competition between different types of magnetic correlations induced by Ag-substitution, giving rise to a magnetically frustrated scenario in Ce2(Pd0.5Ag0.5)2In.Fil: Martinelli, A..

AN ITALIAN VIEW OF ENTREPRENEURSHIP : INTERVIEW WITH ALBERTO MARTINELLI
No full textAlberto Martinelli é professor de Sociologia Econômica e Ciê ncia Política na Università degli Studi di Milano (Universidade de Milão). Também leciona Sociologia na Università Bocconi e trabalhou em outras universidades, como as de Berkeley, Stanford e New York. Suas áreas de pesquisa incluem
empreendedorismo, relações internacionais e políticas sociais. Martinelli é autor de vários artigos e livros, dentre os quais Global Modernization (Sage, 2005), Il Bilancio Sociale (com A. Chiesi e M.
Pellegatta, Il Sole/24 ore, 2000), Recent Social Trends in Italy (com A. Chiesi e S. Stefanizzi, McGill- Queen’s University Press, 1999), International Markets and Global Firms (Sage, 1991) e Economy and
Society (organizado com N. J. Smelser, Sage, 1990).
Martinelli veio ao Brasil para proferir a palestra de abertura do XXXI Encontro da ANPAD no Rio de Janeiro. A entrevista que se segue, realizada ainda na Itália, aborda o campo do Empreendedorismo e sua relação com a Sociologia Econômica, imigração, e se estende a questões de global governance e relações internacionais, temas com os quais vem trabalhando na Universidade de Milão
Sensors and Microsystems. Proceedings of the 9th Italian Conference, Ferrara, Italy, 8 – 11 February 2004
No full textThis indispensable volume contains a selection of papers presented at the 9th Italian Conference on Sensors and Microsystems, organized by AISEM (Associazione Italiana Sensori e Microsistemi). Many essential aspects of the disciplines related to advanced sensors and microsystems are covered, ranging from nano- and new materials to applications, multifunctional systems, micromechanics, and new technology. 83 papers from 103 institutions are featured, an indication of the very active research currently progressing in Italy. The wide range of contributions reflects the multidisciplinary character of the community encompassing physics, chemistry, biology, engineering, medicine, and others
Un nuovo codice con marginalia dello scriba G alias Gian Pietro da Lucca : l’Ambr. M 85 sup. Con una postilla sull’Ambr. A 105 sup. e Costantino Lascaris
No full textThe paper dwells on the origins and the history of two manuscripts now in the Ambrosiana Library: Ambr. M 85 sup. and Ambr. A 59 sup., both in the hand of Pietro Creticus and owned by Giorgio Merula. The A. identifies the hand of Gian Pietro da Lucca in the margins of Ambr. M 85 sup., a fact that strongly supports its alleged provenance from Vittorino da Feltre’s school. Another manuscript owned by Merula, Ambr. A 105 sup., is dated to the XVth century and is ascribed to Costantino Lascaris
A Semi-Classical Approach for Determination of the Inter-Granular Energy-Barrier Height in Very-Fine Nanograins
No full textThe height of the inter-grain energy barrier plays a key role in the determination of the conductive properties of semiconducting nanograins. In the limit of very-fine nanograins (≈ 1 nm), quantum effects start being relevant in the determination of physical properties. We approached the problem in a semi-classical method such as the Thomas-Fermi equation

Medical histology
Medical histology is a modern text more oriented in the "medical" sense, in order to provide students with the tools to frame the subject in the context of preclinical disciplines. In it are presented experimentally acquired data, framed in mechanistic models whose validity is widely confirmed and which contribute to an understanding of the pathophysiological processes. The goal was to provide a model of study of a complex subject, which is also applicable to other disciplines that the student will meet in the course of his medical studies.
The volume has been divided into blocks of teaching material:
• text and figures - essential subjects;
• in-depth analysis with figures - supplementary topics;
• areas of clinical histology - physiopathological correlations;
• extra content in the Virtual Campus web site - additional material available in multimedia format.
Each chapter contains a paragraph concerning the Prerequisites, that is the basic knowledge necessary for a correct classification of the topics covered, a paragraph concerning the Objectives that the study of the topic is aimed at and a Summary of the topic dealt with and concludes with Concepts key to the topics covered.
The topics have been developed highlighting the differentiation mechanisms that allow, in both embryonic and adult life, the exchange and integration of stem cell elements in the context of functional specialized populations. Particular attention was paid to the biomechanical properties of tissues and to the properties of the different populations of adult stem cells, also in consideration of their increasing use, also in association with biomaterials, in regenerative medicine
