Foram analisados 100 dentes primeiros molares e 100 dentes segundos molares superiores, direitos e esquerdos, permanentes, extraídos de humanos, com o objetivo de explorar a região anatômica da furca, mais especificamente realizar medidas das distâncias das aberturas das furcas vestibular, mesial, e distal até à junção esmalte-cemento, e das distâncias das referidas aberturas até às faces radiculares pertinentes: vestibular, mesial, distal e lingual. Utilizou-se para mensuração um microcomputador 486 DX-66Mhz, no qual estava instalado um software analisador de imagens Mocha-Jandel Scientific SigmaScan Pro, version 2.0. Em relação às distâncias das aberturas das furcas até à junção esmalte-cemento foi observado que as distâncias médias para a furca vestibular foram de 3,50mm e 3,03mm; para a furca mesial de 4,44mm e 4,69mm; para a furca distal de 4,26mm e 3,73mm, respectivamente para os primeiros e segundos molares superiores. Em relação às distâncias das aberturas das furcas até às faces radiculares pertinentes foi observado que as distâncias médias da furca vestibular até à face mesial da raiz mesio-vestibular foram de 3,78mm e 3,72mm; da furca vestibular até a face distal da raiz disto-vestibular 3,62 e 3,64mm; da furca mesial até à face vestibular da raiz mesio-vestibular 7,33mm e 6,89mm; da furca mesial até a face lingual da raiz lingual de 4,13mm e 4,33mm; da furca distal até à face vestibular da raiz disto-vestibular de 5,61mm e 5,09mm; da furca distal até a face lingual da raiz lingual de 4,73mm e 4,65mm, respectivamente para os primeiros e segundos molares superiores.

Currently zoos and management centers are valuable tools in the maintenance and study of various species. Studies of behavior of captive animals contribute to the improvement of management techniques and the well - being of themselves, encouraging captive breeding and reintroduction also to the natural environment . One of the ways to increase the levels of well-being is the use of environmental enrichment techniques that provide necessary incentives for the welfare of both physical and psychological captive animal . The aim of this study was to identify the types, frequencies and intensities of behavior displayed by three individuals of the species Galictis cuja, belonging to the family Mustelidae and popularly known as lesser grisson , which are captives in municipal zoo in Piracicaba , SP . In addition to evaluating the influence of environmental enrichment techniques on these behavioral parameters. The animals had their behaviors recorded in ethograms through the focal sampling method , 40 hours per person , totaling 120 hours of observation . Were introduced four environmental enrichment techniques related to physical environment, nutrition , perception and cognitive stimulation . At the end, the results of observations before and after the introduction of enrichment techniques were compared and it was possible to observe significant changes in behavior such as run , walk and scratching . The animals were more active and spent longer visible during the day, the enrichment also increased the frequency of social behaviors and the end of the work occurred even attempted copulation , thus showing that the enrichment exerted a positive influence on the behavioral patterns of lesser grisson (Galictis cuja)

The use of physical characteristics for human identification is known as biometrics. Among the many biometrics traits available, the fingerprint is the most widely used. The fingerprint identification is based on the impression patterns, as the pattern of ridges and minutiae, characteristics of first and second levels respectively. The current identification systems use these two levels of fingerprint features due to the low cost of the sensors. However, the recent advances in sensor technology, became possible to use third level features present within the ridges, such as the perspiration pores. Recent studies show that the use of third-level features can increase security and fraud protection in biometric systems, since they are difficult to reproduce. In addition, recent researches have also focused on multibiometrics recognition due to its many advantages. The goal of this research project was to apply fusion techniques for fingerprint recognition in order to combine minutia, ridges and pore-based methods and, thus, provide more robust biometrics recognition systems, and also to develop an automated fingerprint identification system using these three methods of recognition. We evaluated isotropic-based and adaptive-based automatic pore extraction methods, and the fusion of pore-based method with the identification methods based on minutiae and ridges. The experiments were performed on the public database PolyUHRF and showed a reduction of approximately 16% in the EER compared to the best results obtained by the methods individually

El siguiente proyecto desarrolla un sistema de comunicación gráfica integral del Zoológico de Mendoza. Actualmente la que posee se encuentra desactualizada y alterada. Se construirá un identidad pregnante del organismo y se organiza la información para poder trabajarla a través de una señalética clara que permita al receptor seguir determinados recorridos. La estrategia trabajada, será aplicada sobre diferentes soportes para la promoción y difusión del Zoológico.
