A Case of Unusual Anatomy: Maxillary Central Incisor with Two Root Canals
Rodrigues,Evaldo Almeida; Silva,Sílvio José Albergaria da;
International Journal of Morphology , 2009, DOI: 10.4067/S0717-95022009000300030
Abstract: success in root canal treatment is achieved after thorough cleaning and shaping followed by complete obturation of the canal system. therefore, endodontic therapy requires specific and complete knowledge of the internal and external dental anatomy, and its variations in presentation. such treatment may be performed in root canal systems that do not comply with the normal anatomical features described in standard textbooks. the internal anatomy of the maxillary central incisor is well known and usually presents one root canal system. this case report describes an endodontic retreatment of a maxillary central incisor with two canal systems.
A Case of Unusual Anatomy: Maxillary Central Incisor with Two Root Canals Un Caso de Anatomía Inusual: Incisivo Central Superior con Dos Canales Radiculares

International Journal of Morphology , 2009,
Abstract: Success in root canal treatment is achieved after thorough cleaning and shaping followed by complete obturation of the canal system. Therefore, endodontic therapy requires specific and complete knowledge of the internal and external dental anatomy, and its variations in presentation. Such treatment may be performed in root canal systems that do not comply with the normal anatomical features described in standard textbooks. The internal anatomy of the maxillary central incisor is well known and usually presents one root canal system. This case report describes an endodontic retreatment of a maxillary central incisor with two canal systems. El éxito de los tratamientos de endodoncia sólo puede conseguirse mediante una completa asepsia, el modelado y la obturación del canal radicular. Por ello, los tratamientos de endodoncia requieren de un completo y detallado conocimiento de la anatomía interna y externa de los canales radiculares y de sus variantes. Este tipo de tratamiento puede realizarse en canales radiculares que no coincidan con las características anatómicas normales descritas como patrón por la literatura. La anatomía interna de los incisivos centrales superiores es bien conocida, presentando normalmente un canal radicular único. En este relato se describen los tratamientos endodóncicos de incisivo central superior con dos canales radiculares.
Taxonomia setorial com indicadores de esfor o inovativo Sectoral taxonomy with indicators of innovative effort
Evaldo Henrique da Silva
Revista de Economia Contemporanea , 2013,
Abstract: O propósito deste trabalho é a constru o de uma taxonomia do setor manufatureiro da indústria brasileira, a qual utiliza como critério de classifica o as variáveis indicadoras do esfor o inovativo das firmas. Essa escolha é devida a dois pressupostos. O primeiro é que o desempenho competitivo e econ mico-financeiro no ambito das indústrias está associado ao desempenho inovativo das firmas que as constituem. O segundo pressuposto é de que esse esfor o obedece a imperativos ou regimes tecnológicos que s o específicos de cada indústria ou setor. Foi utilizada exclusivamente a análise de cluster como método de agrupamento. A ênfase nas variáveis consideradas inputs da inova o e o uso exclusivo da análise de cluster s o particularidades dessa taxonomia. Os resultados indicam que a indústria brasileira é dominada por quatro grupos setoriais característicos. Contudo, as diferen as entre esses grupos s o sutis, pois entre as variáveis analisadas s o poucas as que fizeram a diferen a entre os grupos, e essa diferen a n o apresenta desníveis profundos. Suspeita-se da tendência de predomínio de setores considerados como de baixa intensidade tecnológica na indústria brasileira. The purpose of this study is to build a taxonomy of the Brazilian manufacturing industry based on the innovative efforts of the companies. This choice is due to two assumptions. First, competitiveness and financial-economic performance in a given industry is related to the innovative performance of its firms. Second, the innovative effort meets the requirements or technological regimes that are specific to each industry or sector. The use of cluster analyses as the only method of grouping and the emphasis on indicators of innovation inputs are peculiarities of this taxonomy. The results indicate that the Brazilian industry is dominated by four typical groups of sectors - with no deep, significant differences among them - and a predominance of industries with low technological intensity.
Hemangioma capilar da medula: relato de caso
Holanda, Maurus Marques de Almeida;Sarmento, Stênio Abrantes;Andrade, Rodrigo Vasconcelos Correia Lima de;Nóbrega, Evaldo de Sousa;Silva, José Alberto Gon?alves da;
Arquivos de Neuro-Psiquiatria , 2004, DOI: 10.1590/S0004-282X2004000200031
Abstract: we report a rare case of spinal cord capillary hemangioma in a 79-year-old woman, presented with paraparesia that had progressed within 8 months. radiologically, the lesion resemble other vascular spinal cord tumors. the patient underwent surgery and the outcome was good. histologically, the lesion resembled capillary hemangioma of skin or soft tissue, composed of lobules of small capillaries with associated feeding vessels, all enveloped by a delicate fibrous capsule. a review of the published cases in the literature is provided as well as a discussion of the clinical, radiological and histological aspects of the lesion and the differential diagnosis. knowledge of its existence may avoid misdiagnosis of this benign lesion.

Professoras de Educa o Física: duas histórias, um só destino
Luciano de Almeida,Paulo Evaldo Fensterseifer
Movimento , 2007,
Abstract: Este artículo descubre la trayectoria de dos maestras de Educación Física de una escuela de la red pública de San Augusto/RS que, más allá de que se hayan graduado en distintos momentos históricos, producen una práctica similar, caracterizada por la adopción de actividades deportivas con un fin en si mismas. Esa constatación nos lleva a reconocer la necesidad de explicitar las particularidades de la educación escolar, siendo mas especifico de la Educación Física, bien como comprender la Cultura Escolar. La experiencia de la búsqueda de comprensión de las prácticas pedagógicas de otros profesionales puede sumar elementos para que repensemos nuestro propio accionar en la escuela.
O lugar da experiência no ambito da Educa o Física
Luciano de Almeida,Paulo Evaldo Fensterseifer
Movimento , 2011,
Abstract: El presente artículo trae para la discusión el lugar de la experiencia y del saber de la experiencia cómo posibilidad de conocer en el ámbito de las prácticas corporales en la Educación Física. Para eso, recurre a la hermenéutica filosófica de Hans-Georg Gadamer para comprender el movimiento de la Educación Física en legitimarse en distintos espacios sociales, situándola en el tiempo, contextualizando su tradición y los desdoblamientos de esta para la producción del conocimiento. Comprender la experiencia pode nos posibilitar las claves para la comprensión del fenómeno complejo del movimiento humano, ya que esta no puede ser entendida cómo manipulación y control, mas si cómo participación y apertura.
Ensaiando o "novo" em educa??o física escolar: a perspectiva de seus atores
Fensterseifer, Paulo Evaldo;Silva, Marlon André da;
Revista Brasileira de Ciências do Esporte , 2011, DOI: 10.1590/S0101-32892011000100008
Abstract: the paper is a result of a research with teachers who accomplish 'novel' pedagogic practices in the school physical education. it is searched and analyzed the elements that were and are important, in the teachers' view, to support those pedagogic practices. the reports from investigated teachers and the subsequent analysis of the elements pointed out by them, in one side, reinforce the idea that the comprehension of the totality of that phenomena could not be obtained without examining the complex network of relations among the internal and external school determinants; on the other side, neither it is possible to approach the question without considering the professional trajectory of the 'innovator' teacher.

Ambiência , 2012,
Abstract: Resumoé sabido que a escassez de água constitui um forte entrave ao desenvolvimento socioecon mico de uma regi o. Contudo, a preocupa o atual n o se limita apenas com a qualidade e quantidade da água, mas também, com os fatores que as ocasionam. O monitoramento dos recursos hídricos geralmente é uma tarefa morosa e onerosa. Uma técnica que tem demonstrado grande eficiência nestes estudos, com custo relativamente baixo, é o sensoriamento remoto. Nesse estudo, uma série de imagens Landsat5-TM é utilizada na análise da varia o da lamina d’água da lagoa de Parnaguá (PI). Conjuntamente, é verificado se há ou n o influência dos fen menos climáticos El Ni o e La Ni a nessa varia o. Os resultados mostram que existe correla o entre a varia o do espelho d’água da lagoa com os fen menos climáticos El Ni o e La Ni a, embora sejam necessários estudos que me am a utiliza o da água dessa lagoa para outros fins, tais como irriga o e uso doméstico.AbstractIt is known that water shortage can be a strong barrier to a region’s socioeconomic development. However, the current concern is not just with the quality and amount of the water, but also with their causing factors. The monitoring of hydric resources is usually a slow and onerous task. A technique that has shown great efficiency in these studies, with relatively low cost, is the remote sensing. In this study, a series of Landsat5-TM images is used to analyze the variation of the water level of the Parnaguá Pond (PI), Brazil. Jointly, it is verified whether the climatic phenomena El Ni o and La Ni a influence on that variation. The results show a correlation between the variations of the pond’s water surface and the climatic phenomena El Ni o and La Ni a, although it is necessary to carry on further studies to measure the use of the pond’s water for other ends, such as irrigation and domestic use.

Almeida, André Q. de;Ribeiro, Aristides;Paiva, Yhasmin G.;Rascon, Nilton Jr. L.;Lima, Evaldo P.;
Revista Brasileira de Engenharia Agrícola e Ambiental , 2011, DOI: 10.1590/S1415-43662011000400004
Abstract: geostatistics analysis is a powerful tool which has been used in studies of spatial dependence. with respect to the temporal dependence, few analysis are performed with this kind of methodology. in this study, the geostatistics technique was used to adjust a model to a series of temporal values of precipitation and its performance to predict data was also evaluated. the study was carried out at the rio itapemirim basin in a series of monthly precipitation from 1940 to 2006. the adjusted model was compared to the box and jenkins model. the best geostatistics model adjusted was the one which used with 96 neighbors in the prediction and mean relative absolute error of 80.46. geostatistics methodology showed better results for estimating the monthly precipitation in relation to the sarima model (2,1,1)(0,1,1)12.
