O Estado do Acre, território mais recentemente incorporado ao Brasil, até meados do século XIX apresentava em seu território apenas povos tribais ameríndios, que lá habitavam desde milênios. O histórico de povoamento mais recente do estado (a partir da segunda metade do século XIX) está atrelado com o mercado internacional da borracha, a região foi o destino de milhares de pessoas em busca de fazer a vida explorando as seringueiras. A partir de então uma série de disputas fundiárias ocorreram na região, o que foi um dos fatores que influenciaram na conformação da sociedade acreana. O movimento ambientalista surgiu no estado como resultado dessas disputas fundiárias na segunda metade do século XX. No final da década 90 o governo estadual, assimilando o discurso ambientalista, assume o governo com a Frente Popular do Acre, composta por uma série de partidos, com o autodenominado “Governo da Floresta” e usando o neologismo “florestania” como símbolo do projeto do governo. Apesar de utilizar amplamente em seu discurso temáticas ambientais e dos povos da floresta, acabou ao longo dos anos tendo atitudes com um cunho mais doutrinador do que emancipador. A discrepância entre a prática e o discurso do “Governo da Floresta” é então analisada a partir de conceitos como “Ecologia dos Saberes” e “Biopoder”, conceitos que auxiliam na identificação das atitudes de cunho doutrinador postas em prática pelo governo. Considerando como “ecologia dos saberes” aquela forma de conhecimento que tem a premissa um reconhecimento da pluralidade de conhecimentos heterogêneos que em interações sustentáveis e dinâmicas entre eles não comprometem suas autonomias e “biopoder” como aquela forma de poder que exerce a sua dominação sobre a própria vida da população, estabelecendo como é que esses devem viver

The plastic deformation is widely used in the metallurgical market due to its positive factors such as low prices and high speed production. Forming process products are obtained in high quality, both surface quality and mechanical properties. Friction is an importante factor in metal forming. Friction study in metal forming can be accomplished indirectly, such as the ring test of friction. Two samples of different materials being mild steel and copper alloy were used. The results showed the influence of friction in the flow behavior of the deformation of the second phase, as evidenced by standard metallography. It is observed that in the outer regions of the ring, plastic deformation occured in the radial direction. In the central region of the disc deformation occured in the direction of compression and the inner region of the ring flux lines showed a significant deformation in the radial direction towards the center of the ring

In malocclusion studies, may happen not only dental discrepancies but even skeletal discrepancies. In Class III malocclusion can be observed underdeveloped maxilla, mandible protraction or both of them, and, in most of the times associated with a narrow maxilla that causes anterior or posterior crossbites, in one side or in two sides. The aim of this case report is to evaluate the facial profile and occlusal effects of interceptive orthodontics therapy. The treatment with upper arch expansion and maxilla protraction was done in an early age to be effective in the circummaxillary sutural system and to make the orthopedic effect easier. The facial mask used is positioned on two facial points and allows an anterior maxillary replacement. Patients’ compliance is important to reach treatment success, this because using the mask still in this growth and development phase is essential to make the facial and occlusal effects happen. It is important to mention that patients with Angle Class III malocclusion need to be followed till the end of their growth.

The aim of this paper is to offer an essay of synchronous translation poetics, based on the theoretic thought of Haroldo de Campos and Antoine Berman, which highlight the relevance of translation history in the work of contemporary translators. For this purpose, starting from a close-reading of the first seven Latin hexameters of Lucan’s Pharsalia, I present a comparative study of the translations of Filinto Elisio (18th century), José Feliciano de Castilho (19th century) and Vieira (2011).

The pattern of caries lesions has been modified over decades. If the presence or absence of a caries lesion is based upon only a visual examination, its diagnosis might become underestimated since dentinal lesions underneath non cavitated or minimally demineralized enamel is highly frequent in dental clinics. The aim of this paper is to report a clinical case of a child with an upper molar with questionable occlusal aspect, presenting asymptomatic pulpal hyperplasia on the distolingual pit. Periapical radiographic examination was essential for diagnosing hidden caries and elaborating the treatment plan. As part of the approach, removal of the decayed tissue and pulpotomy with calcium hydroxide were performed. The association of an accurate visual examination to an adequate oral radiographyis is extremely important in cases which the presence of hidden caries is doubtful. As a result, an early diagnosis and the reduction of more invasive interventions related to the oral health care of pediatric patients can be achieved as well.

To evaluate the surface roughness and Vickers hardness of glass ionomer cements Ketac Molar® and Ketac Molar Easy Mix® (ESPE Dental AG) after brushing. Methods – After roughness and hardness tests of 14 specimens of each material, they were submitted to 30,000 brushing cycles and new analysis of roughness and hardness. Statistical analysis showed that there was no significant difference between the materials in relation to the initial roughness. Results – However, after brushing there was higher surface roughness for Ketac Molar Easy Mix®. For both materials, there was increase of hardness after brushing and the highest values were presented by Ketac Molar Easy Mix®. Conclusion – It can be concluded that, when choosing a glass ionomer cement for restoration it should be preferred to Ketac Molar, because it showed hardness similar to Ketac Molar Easy Mix, but it was less rough.

The bone resorption in the anterior maxilla, due to its aesthetic importance, can be considered one of the challenges in implant dentistry. Autogenous bone graft is the most indicated bone augmentation procedure, aiming an implant supported rehabilitation.. Alternatively, some other graft procedures can be done with homogenous and xenogenous bone graft, biomaterials and different associations. Additionally to the mentioned biomaterials, the bone morphogenetic protein (BMP), specially the rhBMP-2, which was characterized as a bone osteoinductor, and consecutively, a potential autogenous graft substitute, with previsibility and no necessity of association to other biomaterial. The objective of this study is to present a single case using the rhBMP-2 for bone augmentation.

This study reports an unusual case of acute parotitis in a healthy young adult with good oral hygiene. Case Report: The patient sought the Department of Stomatology, at Ponta Grossa State University due to a swollen on the right parotid gland region. The patient underwent clinical and radiological treatments and was prescribed anti-inflammatory drugs and antibiotics. On the fifth day the signs and symptoms had disappeared. Conclusion: The development of acute parotitis in healthy young adults with good oral hygiene is possible, but this makes the diagnosis more difficult. Anti-inflammatory, antibiotic and heat physiotherapy can contribute to the recovery of the signs and symptoms after 5 days of treatment.
