Abstract: the coronary artery fistulas (fac) are rare and often found occasionally. the conventional treatment can be made by surgical closure with median thoracotomy or with embolization by catheterization. we describe an innovative technique to ligature of fac, on a full endoscopy. women, 45 years with symptomatic fistula between coronary artery anterior descending and trunk artery pulmonary, which took thoracoscopy left, pericardiotomy and ligation of fistula with metal clip without thoracotomy. there were no complications, stayed 24 hours in the icu and was in hospital 4 days. the technique was effective, allows easy accessibility surgical and quick post-operative recovery.
Bioremediation in Mangrove Sediments Impacted by Oil Using Two Types of Fertilizers NPK and OSMOCOTE, Brazil  [PDF]
Danusia Ferreira Lima, Olívia Maria Cordeiro Oliveira, Manoel Jeronimo Moreira Cruz, Jorge Alberto Triguis, Antonio Fernando de S. Queiroz
Open Journal of Marine Science (OJMS) , 2012, DOI: 10.4236/ojms.2012.24015
Abstract: Bioremediation is a technique applied to several environmental impacts, among which the ones generated by petroleum derivatives, through the introduction of microorganisms into the environment, or creating optimal conditions for them to develop. The present study aimed to evaluate the degradation of saturated hydrocarbons through the biostimulation technique in the mangrove sediment impacted by petroliferous activities, testing the potentiality of two fertilizers (NPK and OSMOCOTE) as accelerating agents of the biodegradation of petroleum components, under experimental conditions. In order to understand the bioremediation process it was used the quantification of nutrient contents, the percent of saturated, aromatic and NSO hydrocarbons, and the behavior of saturated compounds along the entire experiment, besides the monitoring of physical and chemical parameters. Chromatographic profiles characterized a major degradation of saturated hydrocarbons at the units with NPK, presenting a better efficiency of this fertilizer in the tested biostimulation process.

ECOLANG - Communications Language for Ecological Simulations Network
Antonio Pereira
Computer Science , 2008,
Abstract: This document describes the communication language used in one multiagent system environment for ecological simulations, based on EcoDynamo simulator application linked with several intelligent agents and visualisation applications, and extends the initial definition of the language. The agents actions and perceptions are translated into messages exchanged with the simulator application and other agents. The concepts and definitions used follow the BNF notation (Backus et al. 1960) and is inspired in the Coach Unilang language (Reis and Lau 2002).

Netto, Antonio Jeronimo;Barros, Péricles Rezende;Jacobina, Cursino Brand?o;Lima, Antonio Marcus Nogueira;
Sba: Controle & Automa??o Sociedade Brasileira de Automatica , 2005, DOI: 10.1590/S0103-17592005000400009
Abstract: in this paper it is proposed a method for estimating in real-time and in closed-loop all the parameters of an induction motor. the parameters are determined by solving a recursive least squares minimization problem. the model for the least-squares problem is derived for the case where the stator currents of the motor are regulated via a linear feedback controller. selected experimental results are used to demonstrate the feasibility and performance of the proposed method.

Journal of Oral & Maxillofacial Research , 2011,
Abstract: Objectives: The aim of this pilot study was to evaluate the effectiveness of cutting needle biopsy in the diagnosis of solid oral lesions.Material and Methods: The biopsies were carried out on seven patients who presented with solid oral lesions with sizes ranging from 2 to 6 cm. Specimens were obtained from each lesion before conventional biopsies using a cutting needle with 18-gauge x 9 cm (MD TECH, Gainesville, FL, USA). A total of 64 specimens processed by hematoxylin-eosin staining method, were obtained. Afterwards, the analysis was performed by an oral pathologist, in two different stages, with and without the clinical history of each lesion. Then, these answers were compared with the final histological diagnosis.Results: Results presented by the descriptive analysis showed that the correct diagnosis using cutting needle biopsy without the clinical history of lesions was registered in 37.5% of cases, while with the clinical history in 76.6%.Conclusions: Despite the promising results as a potential technique for biopsies and histological diagnosis of oral lesions, the cutting needle biopsy should be analyzed carefully in those cases.
