Artemio Zeno y la conformación de un nuevo espacio del conocimiento quirúrgico en Latinoamérica : la dinámica local en la formación de innovadores: Rosario 1910-1940

Resumen: Este artículo se inscribe en investigaciones realizadas para Conicet sobre la incidencia del surgimiento de las facultades rosarinas de la Universidad Nacional del Litoral en la conformación de un sistema regional de innovación científica, y su relación con la dinámica local y la expansión de las redes profesionales. Centra su enfoque en uno de los articuladores del mencionado proceso, el doctor Artemio Zeno, quién fuera fundador de una nueva escuela en la práctica quirúrgica, catedrático titular de la Facultad de Ciencias Médicas de Rosario, empresario de la salud, promotor de publicaciones científicas y de vinculaciones con los principales institutos de investigación internacional, al punto de publicar y dirigir la Revista de Cirugía, del Sanatorio Británico, y crear la primera Fundación médica de Latinoamérica dedicada exclusivamente a becar investigadores de los países del cono sur que quisieran especializarse en la especialidad quirúrgica.

Tratado de pazes, entre os serenissimos e poderosissimos Principes D. Carlos II, Rey Catholico, e D. Afonso VI, Rey de Portugal, feito, e concluso no Convento de Sancto Eloy da Cidade de Lisboa, aos 13 de fevereiro de 1668 : sendo mediator o serenissimo, e poderosissimo Principe Carlos II, Rey da Gram Bretanha

Analisa esse tratado que põe fim às guerras da Restauração de Portugal, mandando devolver a cada uma das partes as conquistas que à outra tiverem feito. Nas colônias, a paz passaria a vigorar um ano após a sua publicação, dado o tempo necessário para que a notícia chegasse à América e à Ásia.

Tratado de limites das conquistas entre os muito altos, e poderosos senhores D. João V, Rey de Portugal, e D. Fernando VI, Rey de Espanha, pelo qual abolida a demarcação da linha meridiana, ajustada no Tratado de Tordesilhas de 7 de junho de 1494, se determina individualmente a raya dos domínios de huma e outra corôa na America Meridional :a de Portugal renuncia o direito, que allegava ter das Ilhas Filippinas, pelo dito Tratado de Tordesilhas, e pela escritura de Saragoça de 22 de abril de 1529 ; e cede a Espanha a Colonia do Sacramento, e o Territorio da margem septentrional do Rio da Prata, que lhe pertencia pelo Tratado de Utrecht de 6 de fevereiro de 1715, como também a Aldea de S. Christóvão, e terras adjacentes, que tinhão occupado os portuguezes entre os rios Japurá, e Isa, que desaguão no das Amazonas; a de Espanha renuncia todo o direito, que pelo dito Tratado de Tordesilhas allegava ter as terras possuidas pelos portuguezes na America Meridional ao Occidente da Linha Meridiana, ajustada naquelle Tratado ; e cede a Portugal todas as terras, e povoações da margem oriental do rio Uruguay, desde o rio Ibicuí para o norte, e a aldea de Santa Rosa, e outra qualquer estabelecida pelos espanhoes na margem oriental do rio Guaporé; com os plenos-poderes, e ratificações dos dous Monarchas, assignado em Madrid a 13 de janeiro de 1750

Thermodynamic and kinetic behavior of an argon plasma jet. Decomposition of nitric oxide between 1300 - 1750 degrees K in an argon plasma

In the first part of the study, an RF coupled, atmospheric pressure, laminar plasma jet of argon was investigated for thermodynamic equilibrium and some rate processes.

Improved values of transition probabilities for 17 lines of argon I were developed from known values for 7 lines. The effect of inhomogeneity of the source was pointed out.

The temperatures, T, and the electron densities, n_e , were determined spectroscopically from the population densities of the higher excited states assuming the Saha-Boltzmann relationship to be valid for these states. The axial velocities, v_z, were measured by tracing the paths of particles of boron nitride using a three-dimentional mapping technique. The above quantities varied in the following ranges: 10¹² ˂ n_e ˂ 10¹⁵ particles/cm³, 3500 ˂ T ˂ 11000 °K, and 200 ˂ v_z ˂ 1200 cm/sec.

The absence of excitation equilibrium for the lower excitation population including the ground state under certain conditions of T and n_e was established and the departure from equilibrium was examined quantitatively. The ground state was shown to be highly underpopulated for the decaying plasma.

Rates of recombination between electrons and ions were obtained by solving the steady-state equation of continuity for electrons. The observed rates were consistent with a dissociative-molecular ion mechanism with a steady-state assumption for the molecular ions.

In the second part of the study, decomposition of NO was studied in the plasma at lower temperatures. The mole fractions of NO denoted by x_NO were determined gas-chromatographically and varied between 0.0012 ˂ x_NO ˂ 0.0055. The temperatures were measured pyrometrically and varied between 1300 ˂ T ˂ 1750°K. The observed rates of decomposition were orders of magnitude greater than those obtained by the previous workers under purely thermal reaction conditions. The overall activation energy was about 9 kcal/g mol which was considerably lower than the value under thermal conditions. The effect of excess nitrogen was to reduce the rate of decomposition of NO and to increase the order of the reaction with respect to NO from 1.33 to 1.85. The observed rates were consistent with a chain mechanism in which atomic nitrogen and oxygen act as chain carriers. The increased rates of decomposition and the reduced activation energy in the presence of the plasma could be explained on the basis of the observed large amount of atomic nitrogen which was probably formed as the result of reactions between excited atoms and ions of argon and the molecular nitrogen.

"Substituir a revolução dos homens pela revolução do tempo" : uma história do conceito de povo no Brasil ; revolução e historicização da linguagem política (1750-1870)

A tese propõe uma linha de interpretação acerca da história do conceito de povo no debate político luso-brasileiro entre a segunda metade do século XVIII e últimas décadas do século XIX, sob uma perspectiva teórica que busca compreender o processo de historicização das linguagens e conceitos políticos como marca do mundo moderno. Procuramos traçar o processo de abalo e desmantelamento dos significados e usos tradicionais e a incorporação crescente da temporalidade histórica na semântica conceitual, fenômeno ocorrido em meio aos conflitos e debates políticos durante a formação, consolidação e crise do estado imperial brasileiro. Acreditamos que nestes anos houve uma acentuada historicizaçao do conceito de povo, processo que teve como marca seu crescente contingenciamento, isto é, sua maior fundamentação em diagnósticos da situação histórica presente, e também sua maior inserção em visões processuais e futuristas da história.

On the existence of Zeno behavior in hybrid systems with non-isolated zeno equilibria

This paper presents proof-certificate based sufficient conditions for the existence of Zeno behavior in hybrid systems near non-isolated Zeno equilibria. To establish these conditions, we first prove sufficient conditions for Zeno behavior in a special class of hybrid systems termed first quadrant interval hybrid systems. The proof-certificate sufficient conditions are then obtained through a collection of functions that effectively "reduce" a general hybrid system to a first quadrant interval hybrid system. This paper concludes with an application of these ideas to Lagrangian hybrid systems, resulting in easily verifiable sufficient conditions for Zeno behavior. © 2008 IEEE.

Lyapunov-like conditions for the existence of zeno behavior in hybrid and lagrangian hybrid systems

Lyapunov-like conditions that utilize generalizations of energy and barrier functions certifying Zeno behavior near Zeno equilibria are presented. To better illustrate these conditions, we will study them in the context of Lagrangian hybrid systems. Through the observation that Lagrangian hybrid systems with isolated Zeno equilibria must have a onedimensional configuration space, we utilize our Lyapunov-like conditions to obtain easily verifiable necessary and sufficient conditions for the existence of Zeno behavior in systems of this form. © 2007 IEEE.

Lyapunov theory for zeno stability

Zeno behavior is a dynamic phenomenon unique to hybrid systems in which an infinite number of discrete transitions occurs in a finite amount of time. This behavior commonly arises in mechanical systems undergoing impacts and optimal control problems, but its characterization for general hybrid systems is not completely understood. The goal of this paper is to develop a stability theory for Zeno hybrid systems that parallels classical Lyapunov theory; that is, we present Lyapunov-like sufficient conditions for Zeno behavior obtained by mapping solutions of complex hybrid systems to solutions of simpler Zeno hybrid systems defined on the first quadrant of the plane. These conditions are applied to Lagrangian hybrid systems, which model mechanical systems undergoing impacts, yielding simple sufficient conditions for Zeno behavior. Finally, the results are applied to robotic bipedal walking. © 2012 IEEE.
