Characterization of Nickel Alloy 600 with Ultra-Fine Structure Processed by Severe Plastic Deformation Technique (SPD)  [PDF]
Waldemar Alfredo Monteiro, Silvio Luis Ventavele da Silva, Luciana Ventavele da Silva, Arnaldo Homobono Paes de Andrade, Luis Carlos Elias da Silva
Journal of Materials Science and Chemical Engineering (MSCE) , 2017, DOI: 10.4236/msce.2017.54004
Abstract: High strength nickel based alloys are used in a multitude of advanced systems where lightweight, high power density mechanical power transmission systems are required. Components such as gears, bearings and shafts could be made significantly smaller and more durable if a major improvement in nickel based alloy mechanical properties could be achieved. An important refinement in grain size (includes nanometric level) is thought to be a promising method for achieving fundamental improvements in mechanical properties. Grain size is known to have a significant effect on the mechanical behavior of materials. One of the most favorable methods of achieving extreme grain refinement is by subjecting the materials to severe plastic deformation (SPD). The principal micro-structural variations in superalloys are the precipitation amount and morphology, grain size and the distribution of carbide precipitation that could reduce the mechanical properties of the alloys. This work shows optical and transmission electron microscopy analysis and also hardness data after severe plastic deformation (pure shear stress).

Academic Management Actions Facing Reforms in Curriculum and in Competencies Required to Graduating from an Accounting Sciences Course  [PDF]
Vilma Geni Slomski, Luciana Regina da Silva Souza, Anísio Candido Pereira, Antonio Carlos Ribeiro da Silva
Creative Education (CE) , 2016, DOI: 10.4236/ce.2016.77095
Abstract: This study aimed to assess academic management actions facing the set of professional competencies that graduates from an Accounting Sciences course need to graduate. To this end, we carried out a qualitative descriptive study. Data were collected through interviews and analyzed using content analysis. We found that the set of graduates’ professional competencies concerning organizational, technical-professional and social spheres requires academic management actions such as: 1) democratic governance and collective development of a curricular pedagogical project; 2) establishment of places for interaction between fields/disciplines (structuring teaching core); 3) use of conflict management strategies; 4) activities that favor professional ethics; 5) activities that favor leadership, commitment and trust; 6) curriculum flexibility; 7) strategic planning and evaluation of actions; 8) professional self-development. Activities and mechanisms that encourage the participation of all those involved in decision-making characterize democratic management and academic management’s leadership. We conclude that democratic-participative management may favor professionals’ graduation processes in the contemporary world, and may be a way of ensuring the development of students’ cognitive, operational, social and moral competencies, through their commitment to curriculum dynamics, to the development of thought and creation processes, to the establishment of participatory citizenship and to ethical education.
O “admirável mundo” de Veja: influências sociais de uma revista de informa o
Carla Luciana Souza da Silva
Historia Actual Online , 2008,
Abstract: En este articulo analizamos los asuntos que son abordados por la revista brasilera Veja acerca de la conducta y el “mundo del espectáculo”. Es solamente como apariencia que ellos suelen ser analizados desde fuera de la economía política, porque ellos son esenciales para e mantenimiento y reproducción del sistema del capital. Ellos se relacionan en el desarrollo de una contra-reforma moral e intelectual, definiendo estilos de vida, lo que es central para el proyecto político y económico que ha sido gestado en los medios de comunicación. La revista actúa concretamente para educar la sociedad acerca del programa político ancho, que no sólo congrega las decisiones políticas sino también el espectro cultural y económico.

Abstract: A bacia do rio Paran (Goiás e Tocantins) com 5.940.382ha, tem alta diversidade de fitofisionomias, incluindo a floresta estacional decidual sobre afloramento calcário, que ainda n o foi estudada nesta regi o. Este trabalho objetivou o levantamento quantitativo da vegeta o arbórea de uma floresta estacional decidual sobre afloramento calcário (13°49'34''S e 46o 41'55''W; 478m de altitude) na fazenda S o José, S o Domingos, GO. Foram demarcadas cinco linhas a intervalos de 100m, onde foram aleatoriamente alocadas 25 parcelas permanentes de 20 × 20m (1,0 ha). Em cada parcela foram amostrados todos os indivíduos com diametro à altura do peito (DAP) igual ou maior que 5cm, onde foram medidos o DAP e a altura, e identificadas as espécies. Foram amostrados 588 indivíduos (536 vivos e 52 mortos ainda em pé), pertencentes a 36 espécies, 31 gêneros e 21 famílias, com índice de Shannon 2,99 e Equabilidade 0,83. As principais espécies em valor de importancia (VI), foram: Tabebuia impetiginosa (43,81), Aspidosperma pyrifolium (35,64), Luetzelburgia sp. (21,77), Commiphora leptophloeos (18,79), Myracrodruon urundeuva (15,79), Pseudobombax tomentosum (13,42), Combretum duarteanum (13,04), Luehea divaricata (12,24), Cabralea canjerana (11,99), Ficus pertusa (11,82), Jacaranda brasiliana (11,68) e Aspidosperma sp. (10,57) que juntas somaram 73,5% do VI total, enquanto as 24 espécies restantes somaram 26,5%. Esta floresta é similar, em termos de diversidade, a outras áreas de afloramentos na regi o.
DE PROTESTOS E LEVANTES: AS REVOLTAS DA VACINA E DA CHIBATA NA MúSICA POPULAR
Luciana Marino Nascimento,Francisco Bento da Silva
Revista Recorte , 2012,
Abstract: The discussion in this paper turns around the causes, impacts and unfolding of two very meaningful events that took place during the initial period of the Brazilian Republic, in the first decade of the 20th century. These events, whose historiographical production is considerably heterogeneous, were called the Vaccine Insurrection (1904) and the Whip Insurrection (1910). The discussion focus on the analysis of song lyrics composed in the epoch or in subsequent periods. Five lyrics are analyzed: three about the Vaccine Insurrection and two about the Whip Insurrection. The songs about the first insurrection are: Rat, rat (1904); Yellow Fever (1907) and Compulsory Vaccination (1904). The ones about the second insurrection are: The claimers (1910) and The master of ceremonies of the sea (1975).
