Vapor chamber heat sink with hollow fins
Michels, Vanessa;Milanez, Fernando H.;Mantelli, Marcia B. H.;
Journal of the Brazilian Society of Mechanical Sciences and Engineering , 2012, DOI: 10.1590/S1678-58782012000300002
Abstract: a new vapor chamber heat sink with maximum fin efficiency is presented. the fins are hollow, so the vapor generated at the base flows up to the top of the fins. as a result, the heat sink is practically isothermal. a prototype of the hollow fin vapor chamber heat sink was built and tested. the prototype presented 20% less overall thermal resistance than conventional pin fin heat sinks with the same mass and volume. a theoretical model for the heat sink thermal resistance was developed and the agreement between the model and the experimental data is fair.
La cautiva como mujer modélica
Mantelli,Nora;
La aljaba , 2005,
Abstract: this article proposes an interpretation not centred on the male of the female character of sophocles's tragedy ajax. the aim is to show that the captive tecmessa, through her silence, her prudence and her devaluation with regard to the woman of the epic constitutes a model representation for the virile archetype of the fifth century.
La cautiva como mujer modélica The captive as model woman
Nora Mantelli
La Aljaba (Luján) , 2005,
Abstract: Este artículo propone una lectura no androcéntrica del personaje femenino de la tragedia de Sófocles, áyax. El objetivo es mostrar que la cautiva Tecmesa, a través de su silencio, su prudencia y su desvalorización con respecto a la mujer de la épica, constituye una representación modélica para el imaginario del arquetipo viril del siglo V. This article proposes an interpretation not centred on the male of the female character of Sophocles's tragedy Ajax. The aim is to show that the captive Tecmessa, through her silence, her prudence and her devaluation with regard to the woman of the epic constitutes a model representation for the virile archetype of the fifth century.
Salvadora interpela el canon epistémico: Acerca de la categoría de género como contenido de ense?anza de la literatura. El caso de Salvadora Medina Onrubia
Mantelli,Nora; Sardiello,Natalia;
La aljaba , 2011,
Abstract: the inclusion of salvadora medina onrubia (la plata, 1894-buenos aires, 1971) in the secondary school literary canon constitutes one possible way of working on the issue of genre as teaching content. in this article, we study the convergence of feminine and anarchist assertions in the narrative texts of this author, the intent of her discourse and the reading public to whom it is addressed. secondly, we evaluate the possibility of including salvadora medina onrubia′s fiction in the reading repertoire for secondary education.

Abstract: La inclusión de Salvadora Medina Onrubia (La Plata, 1894-Buenos Aires, 1971) en el canon literario escolar de la escuela media constituye un modo posible de trabajo sobre la problemática de género como contenido para la ense anza. En este artículo, exploramos la convergencia de reivindicaciones femeninas y anarquistas en los textos narrativos de esta autora, la intencionalidad de sus discursos y el público lector al cual se dirige. En segunda instancia, evaluamos la posibilidad de incluir los relatos ficcionales de Salvadora Medina Onrubia en el repertorio de lecturas para la ense anza media.

Non-linear Coulomb blockade microscopy of a correlated one-dimensional quantum dot
D. Mantelli,F. Cavaliere,M. Sassetti
Physics , 2012, DOI: 10.1088/0953-8984/24/43/432202
Abstract: We evaluate the chemical potential of a one-dimensional quantum dot, coupled to an atomic force microscope tip. The dot is described within the Luttinger liquid framework and the conductance peaks positions as a function of the tip location are calculated in the linear and non-linear transport regimes for an arbitrary number of particles. The differences between the chemical potential oscillations induced by Friedel and Wigner terms are carefully analyzed in the whole range of interaction strength. It is shown that Friedel oscillations, differently from the Wigner ones, are sensitive probes to detect excited spin states and collective spin density waves involved in the transport.
Nature of the global fluctuations in the spherical model at criticality
Jean-Yves Fortin,Sophie Mantelli
Physics , 2012, DOI: 10.1088/1751-8113/45/47/475001
Abstract: We study the universal nature of global fluctuations in the critical regime of the spherical model by evaluating the exact distribution of the magnetization and its absolute value in the thermodynamical limit, in the presence of a conjugate field. We show that the probability distribution function for this model is described by non-Gaussian asymptotics and non-symmetric characteristics which depend on the dimension of the system 2
UNION DISCO-VERTEBRAL: ?QUE ES LO PATOLOGICO?
Durán H,Fernando;
Revista chilena de radiología , 2003, DOI: 10.4067/S0717-93082003000200004
Abstract: the purpose of this review is to discuss the concepts of normality, anatomical variations and changes occurring in the "annulus _ disc complex" as a result of aging and disease. new concepts and nomenclature currently in use will improve the information that surgeons receive from radiologists.
UNION DISCO-VERTEBRAL: QUE ES LO PATOLOGICO?
Fernando Durán H
Revista Chilena de Radiología , 2003,
Abstract: Se revisan los conceptos de normalidad, variaciones anatómicas y cambios patológicos de la unión discovertebral, actualmente aceptados en la literatura internacional. La utilización de esta nomenclatura permitirá un mejor correlato clínico radiológico, entregando información útil para los clínicos y cirujanos. The purpose of this review is to discuss the concepts of normality, anatomical variations and changes occurring in the "annulus _ disc complex" as a result of aging and disease. New concepts and nomenclature currently in use will improve the information that surgeons receive from radiologists.
On Managerial Incentives, Performance Indicators and Efficiency Audits in Public Enterprises On Managerial Incentives, Performance Indicators and Efficiency Audits in Public Enterprises
Fernando H. Navajas
Revista de Análisis Económico (RAE) , 1987,
Abstract: On Managerial Incentives, Performance Indicators and Efficiency Audits in Public Enterprises This article discusses the issues of the selection of performance indicators and the design of efficiency audits in public enterprises following a standar principal-agent model. First, using a well known proposition on the value of information we argue that there must exist a limit to the number of performance indicators employed and that some broadly advocated measures such as productivity indices may be redundant if a well defined (ourcomebosed) bonus incentive scheme is already in use. Second, following recent theoretical research on managerial accounting we interpret efficiency audits as condition of information mechanisms or costly investigations that are triggered only in specific circumstances, which depend on the extreme realisations of the outcome used to evaluate managerial performance.
