O artigo apresenta pressupostos teóricos e metodológicos relevantes para a interpretação das interações estabelecidas entre mineração e desenvolvimento regional. É refutada a hipótese de que os mecanismos de mercado afastam a irreversibilidade dos processos entrópicos, como defende a economia dos recursos naturais de inspiração neoclássica. Refuta-se também a noção de que a degradação entrópica, do ponto de vista social, é, inexoravelmente, negativa, como pressupõe a economia ecológica. Como alternativa analítica, indicam-se abordagens que interpretam a sociedade capitalista como um sistema longe do equilíbrio e sustenta-se que as repercussões sociais da degradação entrópica decorrente da mineração vinculam-se ao modo de interação entre competências técnicas, características históricas, sociais, culturais, políticas e especialidades e potencialidades naturais de uma determinada formação social.

People store data of the most different daily events, to know yourself, detect behaviors, predict events and have an strongly knowledge to take decisions. The growth of the events, results in a large amount of data colected and this data needs to be processed to get value information. This data have a temporal component from the collect process (daily, monthly or annualy) and this need to be consider on the exploration. The exploration based on temporal component can be uni-scale or multi-scale. The data mining goes toward to extract knowledge from large databases and if combined with visualization tools, the data mining can be more effective to detect information. This visualization tools display data and allow user to manipulate and change it by interaction features toward your goal. The user can combine tools and combine the steps of visualization among the tools through messages. This monograph aim to insert interactivity on AdaptaVis architecture model, developed by Shimabukuro (2004), the InfoVis, then extends its ability of exploration and provide a consistent base for the user handle data and extract information

This paper aims to develop a web application for viewing Atmospheric Electrical Discharge, plotting marks on a map, using as base data provided by SIMEPAR. The developed system uses techniques and tools which enable the creation of Web system without requiring the use of plugins or external software, running on virtually all web browsers and platforms. This tool aims to aid meteorologists monitor agile discharges and help society at large to prevent accidents caused by this phenomenon of nature

Delivering to the customers a product or service with the expected quality associated to the huge competitiveness that exists in the market nowadays, has been making organizations increasingly focus on quality planning using techniques which are directed towards the continuous improvement process and production optimization. Thus, this paper aims to improve a machining process using the techniques of experimental design to the optimization and this also includes the analysis of the measurement system. For this purpose, the alloy Nimonic 80A, a nickel base superalloy, was used in the process due to its widespread use for high temperatures, applying this study the robust method proposed by Genichi Taguchi, determining the influence of the factors considered input variables, cutting speed, feed rate, depth of cut, type of tool, lubrication, and material hardness, in the output or response variable, surface roughness, concluding with the use of Taguchi orthogonal array L16 and by analysis of ANOVA that the factor feed rate is significant and offers greater effect on the response variable studied, should be set to 0,12mm/rev. Moreover, the factor type of tool has more influence on the process when compared to other factors, being CP250 the one more suitable to the process. Lastly, the interaction feed rate x cutting speed provides greater significance in the process regarding to surface roughness variable, being the best match between them 0,12mm/rev to the feed rate and 90m/min to the cutting speed. In order to evaluate the measurement system, it was applied the repeatability and reproducibility method (R&R), through which we saw that the system needs improvement (R & R = 88.04% >>> 30%) as the value found in the study was well above compared to the one that classifies the system as inappropriate

Os hormônios esteróides anabólico-androgênicos (EAA) compreendem a testosterona e seus derivados. Atletas e não atletas interessados em aumentar o desempenho esportivo, a força, a aparência física e a massa muscular têm utilizado esteróides anabólico-androgênicos sintéticos (EAAs) sem indicação médica. O uso de EAAs pode causar câncer de próstata, doença coronariana e esterilidade. No presente trabalho, avaliou-se os efeitos de altas doses de decanoato de nandrolona, do exercício físico resistido e da interação desses fatores sobre os lobos prostáticos de ratos machos adultos. Vinte ratos foram divididos aleatoriamente em quatro grupos experimentais e tratados e pesados por oito semanas: Esteróide + Exercício (EE), Sedentário + Esteróide (ES), Veículo + Exercício (VE) e Veículo + Sedentário (VS). Eles receberam injeção i.m de decanoato de nandrolona (5mg/Kg) e veículo (propilenoglicol) (0,2 mL/Kg). O peso absoluto corpóreo e do lobo ventral da próstata foi aferido. Os lobos prostáticos foram coletados, dissecados e processados, empregando-se técnicas microscópicas (histológicas, histoquímicas e imunohistoquímicas) e morfométricas. Os dados foram analisados por ANOVA bifatorial e Tukey (p<0,05). Alterações estatisticamente significativas nas massas corpórea, do lobo ventral, no índice de proliferação celular, na população de células basais e na análise dos volumes relativos dos componentes prostáticos (epitélio, estroma e lúmen) foram observadas. O decanoato de nandrolona determinou o aumento da proliferação celular, sugerindo o desenvolvimento da hiperplasia hormonal. De modo geral, as respostas não foram homogêneas para os parâmetros analisados, visto que os tecidos apresentam níveis de expressão de receptores de andrógenos, afinidade de ligação e vias metabólicas de conversão...

A virtual studio system can use technologies as augmented reality and digital matting to decrease production costs at the same time it provides the same resources of a conventional studio. With this, it’s possible for the current studios, with low cost and using conventional devices, to create productions with greater image quality and effects. Some difficulties are recurrent in virtual studio applications that use augmented reality and digital matting. The virtual objects registration in augmented reality techniques suffer from problems caused by optical distortions in the camera, errors in the marker tracking system, lack of calibration on the equipments or on the environment (lighting, for example), or even by delays in the virtual objects display. On the other hand, the digital matting’s main problem is the real-time execution to preview the scene, which must have optimized processing speed at the same time while maintain the best image quality possible. Taking the given context into consideration, this work aims to give continuity to a virtual studio system called ARStudio, by enhancing digital matting, virtual objects registration and introducing a segmentation based on depth map, yet adding better control over functionalities previously implemented

The development of new dental materials has expanded dental therapeutic modalities ensuring excellence in aesthetic restorative treatments. Thus, the direct restorative procedures have been used in cases of dental reconstruction allowing an effective treatment with a low cost, while preserving healthy tooth structure. However, the clinician must be used to the techniques and the material in order to ensure longevity and success in the direct restorative procedure. The aim of this paper is to descrive, after completion of periodontal surgical procedures, the direct restorative step performed for dental reconstruction and diastema closure. The integration between Restorative Dentistry and periodontics enableb the restoration of a harmonious smile in a conservative manner, ensuring aesthetics and patient stisfaction.
