Durante a usinagem dos blocos de zirc?nia para diversos tipos de implantes odontol?gicos, grande parte do material ? desprendida na forma de p?, que posteriormente ? descartado. A zirc?nia tetragonal estabilizada com 3% em mol de ?tria (Y-TZP) possui uma variedade de aplica??es na ?rea de engenharia e biom?dica devido ? sua ?tima combina??o de resist?ncia, tenacidade ? fratura, condutividade i?nica e baixa condutividade t?rmica. Al?m do dano para o meio ambiente, o desperd?cio deste material resulta em preju?zo financeiro, refletindo em elevado custo final no tratamento para os pacientes. Os materiais de partida utilizados neste trabalho foram dois diferentes p?s do sistema cer?mico ZrO3-Y2O3: zirc?nia comercial nanoparticulada e res?duo de zirc?nia microparticulado. Os p?s foram conformados por prensagem uniaxial e isost?tica e em seguida sinterizadas a 1500, 1550 e 1600 ?C, durante 1 hora. As t?cnicas de granulometria a laser, difra??o de raios X (DRX), e dilatometria foram utilizadas para caracteriza??o do p?. Ap?s sinterizados, foram realizados ensaios de densidade e porosidade, difra??o de raios X (DRX), resist?ncia mec?nica ? flex?o, microdureza Vickers e an?lise de tenacidade ? fratura, e microscopia eletr?nica de varredura (MEV). As amostras compactadas via prensagem isost?tica apresentaram valores de porosidade inferiores a 0,78% e demostraram maior efetividade de compacta??o comparada ? via uniaxial. Foi observado nos difratogramas de raios X, com o aumento da temperatura, a intensidade dos picos da fase monocl?nica diminuiu. A temperatura de sinteriza??o influenciou de forma moderada a microdureza das amostras, demostrando pequenos acr?scimos da dureza at? a temperatura de 1600?C. A resist?ncia ? flex?o do res?duo de zirc?nia aumenta com o aumento da temperatura de sinteriza??o, para ambas as vias de compacta??o, apresentando melhores valores por via isost?tica. / The actual use of natural resources on accelerated economic growth, resulting in continuous increase of industrial waste, and to remove these residues, a recycling process is preferably na attractive solution. During the machining of blocks of zirconia to several types of dental implants, most of the material is loosened as a powder, which is subsequently discarded. The stabilized tetragonal zirconia with 3% yttria (Y-TZP) mol boasts a variety of applications in engineering, and biomedical, because of its great combination of strength, fracture toughness, ionic conductivity and low thermal conductivity. Besides the damage to the environment wasting of the material resulting in financial loss, reflecting the high final cost of medical treatment for patients. The starting materials used in this work were two different powders ZrO3-Y2O3ceramic system: commercial zirconia nanoparticulate and microparticulate zirc?nia residue. The powder was uniaxially and isostatically pressed and then sintered at 1500, 1550 and 1600 ? C for 1 hour. The techniques of laser granulometry, X-ray diffraction (XRD) and dilatometry were used for powder characterization. After sintering were performed density and porosity tests, X-ray diffraction (XRD), Flexural strength, microhardness and fracture toughness analysis, and scanning electron microscopy (SEM). Samples compacted via isostatic pressing showed values less than 0.78% porosity and demonstrated greater effectiveness compared to uniaxial compression. Was observed in X-ray diffra ction, that with increasing temperature, the intensity of the peaks of monoclinic phase is decreased. The sintering temperature moderately has influenced on the microhardness of samples, showing small increases in hardness to temperature of 1600 ? C. The flexural strength of zirconia residue increases with increasing sintering temperature for both routes of compression, showing the best values for isostatic compression.

Por?m, o processo que levou a esse afastamento da pris?o em rela??o ao espa?o urbano de Natal havia come?ado tr?s d?cadas antes. A funda??o da Col?nia Penal ?Doutor Jo?o Chaves? no munic?pio de Maca?ba, e posteriormente, sua transfer?ncia para Igap?, no munic?pio de Natal, envolvem quest?es pol?ticas e sociais que agem sobre a defini??o do lugar que a pris?o deveria ocupar na cidade. Neste trabalho, pretendemos analisar o fen?meno do afastamento da pris?o em rela??o ao espa?o urbano da cidade de Natal, entre 1940 e 1975. Buscaremos investigar as rela??es que se estabeleciam entre a pris?o e a cidade de Natal, com base no modo como as pris?es aqui estudadas s?o enunciadas nos jornais e pensadas por seus planejadores, o que sofre interfer?ncias, entre outros fatores, das diferentes identidades espaciais contidas no territ?rio da cidade. Mas tamb?m buscaremos perceber a maneira como os sujeitos ligados ? pris?o, sobretudo os presos, interagem com o espa?o urbano. Abordaremos a pris?o enquanto institui??o planejada por parte do Estado, cujas expectativas envolvem rela??es pol?ticas locais e nacionais, mas tamb?m envolvem um projeto de como deveria ser a cidade. Contudo, este trabalho tamb?m ? uma tentativa de analisar o preso como sujeito em intera??o com a sociedade intra e extramuros, atrav?s de suas formas de adapta??o e resist?ncia ao encarceramento. / In 1970, the penal colony called Casa de Deten??o de Natal was disabled, located in the neighborhood of Petropolis, replaced by the penal colony called Col?nia Penal Doutor Jo?o Chaves, located in an environment of rural characteristics, the neighborhood of Igap?. However, this process of replacing had begun three decades earlier. The foundation of the Penal Colony "Jo?o Chaves" in the city of Maca?ba, and later its transfer to Igap?, in Natal, has political and social questions which act on the definition of the place that the prison should take in the city. In this thesis, we intend to analyze the phenomenon of the prison removal in relation to the urban space of the city of Natal, between 1940 and 1975. We will seek to investigate the relationships established between the prison and the city of Natal, based on how the prisons here are studied and set out in the newspapers and thought by its planners, it may be interfered, among other factors, in the different spatial identities contained in the city. But we also seek to understand how the subjects linked to prison, especially the prisoners, interact with the urban space. We address the prison as an institution planned by the state, whose expectations involve local and national political, but also involve a project as it should be the city. However, this study is also an attempt to analyze the prisoner as a subject in coordination with the intra and extramural society through their ways of adaptation and resistance to incarceration.

Neste lugar chegaram a reunir-se cerca de 6.600 homens e mulheres pobres livres, fugindo da terr?vel seca de 1877, mas tamb?m motivados pela promessa de acesso aos g?neros de primeira necessidade, moradia e cuidados m?dicos, mediante trabalho, como defendiam os representantes do poder local e central. No entanto, n?o foi isso que os retirantes efetivamente encontraram, j? que as condi??es dentro do estabelecimento agr?cola chamavam aten??o pela pen?ria e viol?ncia, conforme den?ncia apresentada nos relat?rios presidenciais daquela ?poca. Este trabalho tem o objetivo de analisar os conflitos ocorridos na Col?nia Sinimb?, procurando enfatizar as tens?es e interesses dos representantes das elites locais e do governo central, relacionados ? constru??o e posterior fechamento desse espa?o, num contexto marcado pelos debates acerca do controle do trabalhador pobre livre. Assim, procuraremos demonstrar que, se por um lado, foram criados espa?os institucionalizados que visavam submeter o nacional livre a uma l?gica de trabalho pautada na disciplina do corpo, no controle do tempo e no ordenamento do espa?o, por outro n?o se pode desconsiderar as diferentes formas de resist?ncia impostas pelos homens e mulheres pobres livres, submetidos ao processo de reordenamento do mundo do trabalho. / In 1878, at the province of Rio Grande do Norte, between Cear?-Mirim and Extremoz, was founded the Agricultural Colony of Sinimb?. On this location, about 6,600 freed men and women had gathered. They were not only fleeing from the terrible 1877 drought but also encouraged by the promise of accessing basic necessities, i.e. housing and medical assistance, upon work, as required by local and central representatives of power. However, the migrants faced otherwise reality, since conditions within the agricultural facility were of shortage and violence, as denounced on the presidential reports of that time. This work aims at analyzing the conflicts that took place at the Sinimb? Colony, while it seeks to emphasize how the tensions and interests of both local elite and central government representatives relate to the opening and closure of this space, on a context where the debate on the control over freed poor workers was on the rise. Thus, we intend to demonstrate that on the one hand, institutionalized places provided the native freed a sense of work guided by the discipline of the body, control of time and arrangement of space. On the other hand, unlike forms of resistance enacted by freed working men and women undergoing the rearranging process of labor world cannot be disregarded.

However, failures associated with chipping and delamination of the veneering porcelain from zirconia substructure still high when compared to metal-ceramic systems. This study aimed address these problems by improving the mechanical strength of veneering porcelain and by improving its adhesion to zirconia substrate. First, the addition of a stronger ceramic second phase (zirconia particles) to feldspathic porcelain was studied. This study began with the preliminary characterization of zirconia synthesized by Complex Polymerization Method (CPM) and commercial zirconia. It was found that the synthesized zirconia did not show improved properties when compared to commercial zirconia. Commercial zirconia powders were thus used thereafter. The influence of the type of powder (pre-sintered or agglomerated) in the mechanical properties and wear of porcelain composites (20vol.%) was evaluated. The pre-sintered powders increased the mechanical strength and wear of the composites compared to agglomerated powders. Then, it was determined the amount of second phase (0-50vol.%) that maximizes the mechanical properties of the porcelain-zirconia composites. It was concluded that the composites with 30vol.% of zirconia showed the best results for wear and flexural strength (198.5MPa). Finally, it was evaluated the influence of the type of surface treatment (sandblasting or holes) and the deposition of a composite interlayer (porcelain reinforced with 30vol.% of zirconia), on the zirconia surface, on the bond strength between the veneering porcelain and the zirconia substructure. The highest bond strength values were found for specimens having simultaneously holes on the surface of zirconia and the composite interlayer between the zirconia substructure and the veneering porcelain (138 ? 19MPa). It was demonstrated that the correct configuration of the interface between the zirconia substructure and the veneering porcelain can lead to all-ceramic restorations with enhanced mechanical strength and improved clinical performance. / Materiais comp?sitos restauradores representam um dos mais bem sucedidos biomateriais na pesquisa moderna, na substitui??o do tecido biol?gico em apar?ncia e fun??o. Nesta linha, a porcelana feldsp?tica tem sido largamente usada em odontologia devido suas interessantes qualidades como estabilidade de cor, propriedades est?ticas, elevada durabilidade mec?nica, biocompatibilidade, baixa condutividade t?rmica e elevada resist?ncia ao desgaste. Entretanto, este material ? fr?gil e pode falhar em ambiente oral devido ao micro-vazamento, baixa resist?ncia ? tra??o, descolagem ou fratura. Assim, para melhorar as propriedades mec?nicas da porcelana, a zirc?nia parcialmente estabilizada com ?tria (Y-TZP) pode ser uma boa alternativa para fortalecer e produzir infraestruturas totalmente cer?micas (coroas e pr?teses parciais fixas). Portanto, este estudo tem por objetivo avaliar as propriedades mec?nicas e caracter?sticas microestruturais da porcelana refor?ada com zirc?nia (3Y-TZP) em diferentes conte?dos e as vari?veis que afetam as propriedades mec?nicas destes materiais. O estudo de caracteriza??o revelou que a zirc?nia comercial apresenta melhores resultados quando comparada com a zirc?nia sintetizada pelo CPM. Assim, os estudos seguintes utilizaram a zirc?nia comercial para todos os testes requeridos. As part?culas de zirc?nia apresentam elevadas propriedades mec?nicas quando comparadas a zirc?nia aglomerada. Os diferentes conte?dos revelam que as propriedades mec?nicas dos comp?sitos aumentam com o aumento do conte?do volum?trico at? 30% vol.% (198,5Mpa), ou seja, maior resist?ncia ? flex?o quando comparada com os outros comp?sitos. Do mesmo modo, a resist?ncia ao desgaste para os comp?sitos com (30%, vol.% de zirc?nia) apresenta valores superiores quando comparado aos demais comp?sitos. Na ades?o cer?mico-cer?mico a porcelana exibe elevada ades?o para a superf?cie de zirc?nia porosa quando comparada a superf?cie rugosa. Os furos superficiais (PZ) e aplica??o de comp?sitos com camada intermedi?ria (RZI) na zirc?nia causam separadamente uma melhoria da resist?ncia ao cisalhamento da zirc?nia-porcelana quando comparados as amostras convencionais de zirc?nia-porcelana (RZ), embora n?o sejam estatisticamente significativas (p>0.05). A presen?a de uma camada intermediaria produz um aumento significativo na for?a de liga??o (~55%) em rela??o as amostras convencionais (RZ). Portanto, a correta a correta configura??o e tratamento superficial podem produzir subestruturas com qualidade e for?a de liga??o adequadas aos requisitos odontol?gicos.

Ten genera historically included in the tribe are assumed as ingroup in the present analysis, which comprises: Aposturisoma, Cteniloricaria, Farlowella, Harttia, Harttiella, Lamontichthys, Metaloricaria, Pterosturisoma, Sturisoma and Sturisomatichthys. The ingroup encompasses 78 terminal taxa plus 22 belonging to the outgroup which were chosen from other subfamilies of the Loricariidae and genera of the Loricariini. Seven molecular markers were included for the phylogenetic analysis, the mitochondrial Cytb, nd2, 12S and 16S, and the nuclear MyH6, RAG1 and RAG2. Additionally, 216 morphological characters are included, which encompasses characters proposed by previous authors and new characters proposed herein including both osteology and external morphology. A Maximum Parsimony analysis and a Bayesian Inference analyses were carried out using the concatenated matrix which is comprised by 6,839 characters. Thirty most parsimonious trees were found with a length of 18.254 steps, consistency index (CI) of 0.37 and retention index (RI) of 0.59, a consensus tree was obtained and showed a paraphyletic Harttiini sensu Isbr?cker; the same result was obtained from the Bayesian Inference analysis. Harttiini comprises Harttia, Harttiella and Cteniloricaria. Farlowellina is elevated to the tribe rank as Farlowellini, encompassing Farlowella, Lamontichthys, Pterosturisoma, Sturisoma and Sturisomatichthys; Aposturisoma is here suggested as junior synonym of Farlowella. Metaloricaria is assigned to the monotypic Metaloricariini. On the other hand, the Loricariini is here restricted to a unique group without a subtribal division, contrary to what was proposed in previous studies. Sturisoma was corroborated here to be strictly cis-Andean, while Sturisomatichthys encompasses, besides the valid species already included in the genus, the trans-Andean species belonging to Sturisoma sensu lato. Two new species of the former and one new species of the latter were recognized. A new classification for the Loricariinae is offered, as well as for identification keys for the genera of both the Harttiini and the Farlowellini. Discussions regarding the taxonomy of the genera found to be valid are offered. Furthermore, a taxonomic revision of Sturisomatichthys is presented. A total of 358 specimens including both type an non-type specimens of all valid species were examined. Sturisomatichthys was found to encompass 12 valid species: Sturisomatichthys aureus, S. caquetae, S. citurensis, S. dariensis, S. festivus, S. frenatus, S. kneri, S. leightoni, S. panamensis, S. tamanae. In addition, two new species are described, Sturisomatichthys Baud? n.sp. from the Baud? River, in Northwestern Colombia, belonging to the Caribbean slope of the continent, and Sturisomatichthys San Juan n.sp. from the San Juan River basin in western Colombia, on the Pacific slope. Sturisomatichthys caquetae, from the Morelia River, upper Amazon, is transferred back from Sturisoma and S. leightoni is distributed, besides the Magdalena-Cauca basin, in the Orinoco basin; thus, Sturisomatichthys is discovered to be distributed in both trans- and cis-Andean drainages. A neotype is designated for S. aureus from the Lower Magdalena basin, type locality of the species. New records of localities in the Northwestern region of South America, as well as the redescription and taxonomic comments of all valid species, are provided. Maps with the distribution of the genus and a key of identification of the species are provided. / Uma an?lise de evid?ncia total de Harttiini sensu Isbr?cker ? apresentada.

Seventy-five zirconia ceramic samples were obtained and divided into five groups (n=15): G1 ? Scothbond Universal (SBU); G2 ? silane + SBU; G3 - Signum Zirconia Bond; G4 - Z-Prime Plus; G5 - MZ Primer. A cone of composite resin was built. The specimens were stored in 100% relative humidity with distilled water at 37?C for 48 h, and then submitted to a tensile bond strength test in a universal testing machine at a crosshead speed of 0.5 mm/min. The type of failure that occurred during the debonding procedure was analyzed. The mean results of the bond strength test (MPa) followed by the same letter represent no statistical difference by ANOVA and Tukey?s post-hoc test (p<0.05): G2=27.55a (?6.99), G4=23.71a (?5.65), G1=22.64a (?5.67), G5=13.64b (?5.49), G3=7.54c (?4.75). G2 and G4 exhibited predominantly cohesive failure in the resin composite cone. G1 and G5 had predominantly mixed failures, and G3 exhibited only adhesive failures. The SBU and Z-Prime Plus provided higher bond strength to zirconia ceramic. / (Artigo Os adesivos universais s?o t?o eficientes quanto um primer para a ades?o ? zirc?nia?)

Materials and methods: Forty RN (regular-neck, Straumann) implant analogs and 4.0 mm solid abutments (Straumann) were embedded in acrylic resin and divided into 5 groups (n = 8): 1) e.max CAD; 2) Celtra Duo; 3) Incoris zirconia TZI; 4) 0.6 mm zirconia coping + e.max CAD; 5) 0.3 mm zirconia coping + e.max CAD. After preparation of the specimens, they were subjected to mechanical fatigue testing with 200N and 500,000 cycles. Following, the samples were submitted to the fracture resistance testing. Results: the means in Newtons (N) were as follows: e.max CAD 210.6Na ? 1447; Celtra Duo 2026Nb ? 355.8; zirconia TZI 2850Nc ? 287.6; 0.6 mm coping + e.max CAD 851Nd ? 108.1; 0.3 mm coping + e.max CAD 980Nd ? 133. Conclusion: monolithic translucent zirconia crowns cemented on solid abutments showed the higher fracture resistance in comparison to lithium dissilicate (e.max CAD) and lithium silicate reinforced by zirconia (Celtra Duo). The use of a zirconia coping associated with lithium dissilicate does not promote superior fracture resistance than monolithic crowns regardless of the thickness of coping and veneering ceramics. / Objetivos: 1) Avaliar a resist?ncia ? fratura de coroas cer?micas de dissilicato de l?tio, silicato de l?tio refor?ada por zirc?nia e zirc?nia transl?cida cimentadas sobre pilares s?lidos; 2) Avaliar se a presen?a de um coping em zirc?nia pode aumentar a resist?ncia ? fratura de coroas de dissilicato de l?tio quando comparadas ?s cer?micas monol?ticas confeccionadas em dissilicato de l?tio, zirc?nia transl?cida ou silicato de l?tio refor?ada por zirc?nia cimentadas sobre pilares s?lidos. Materiais e m?todos: Quarenta an?logos de implantes RN (regular neck, Straumann) e pilares s?lidos 4.0mm (Straumann) foram inclu?dos em resina acr?lica e divididos em 5 grupos (n=8) os quais receberam as seguintes coroas prot?ticas cimentadas: 1) e.max CAD; 2) Celtra Duo; 3) zirc?nia Incoris TZI; 4) coping zirc?nia 0,6mm + e.max CAD; 5) coping zirc?nia 0,3mm + e.max CAD. Ap?s confec??o dos corpos de prova os mesmos foram submetidos ? fadiga mec?nica com carga de 200N e 500.000 ciclos. Na sequ?ncia foram submetidos ao ensaio de carga m?xima de carregamento. Resultados: as m?dias de resist?ncia ? fratura obtidas foram: e.max CAD 1447Na ? 210,6; Celtra Duo 2026Nb ? 355,8; zirc?nia TZI 2850Nc ? 287,6; coping 0,6mm + e.max CAD 851Nd ? 108,1; coping 0,3mm + e.max CAD 980Nd ? 133. Conclus?o: Coroas monol?ticas realizadas em zirc?nia transl?cida cimentadas sobre pilares s?lidos apresentaram a maior resist?ncia ? fratura quando comparadas ao dissilicato de l?tio (e.max CAD) e silicato de l?tio refor?ado por zirc?nia (Celtra Duo). O uso de um coping de zirc?nia associado ao dissilicato de l?tio n?o promove resist?ncia ? fratura superior as coroas monol?ticas independentemente das espessuras do coping e da cer?mica de cobertura.

This way, it relativizes the civilization?s approaches, presenting shards of a road network and spread preexistent neighborhoods, deeply related to the natural landscape, structured according the way of life and imagination of their inhabitants and where ideas and goods that supplied the internal market traveled. At the same time, they worked as communication channels with areas already considered urbanized, from where came diluted influences built from the diversity of beings and ways. This culturally diverse landscape shaped a perception of the urban environment compatible to the existing rural way of life and adapted to the reality and possibilities of the rural population. Therefore, the cultural landscape was the base for the insertion of the administrative network then consolidated the modern regional territoriality. Like stacked layers, intersection and detachment moments are observed, influenced by the encounters, conflicts, dialogs, resistances and redeterminations of the landscape itself and the network. The failure in immediately complying with an external urbanizing model, makes this process peculiar, consistent with the local culture and detached from the belle ?poque concept. This regionalist urbanity kept rustic cultural aspects that justified its spatial features and the organization method of the society around communities, where the production and genealogy defined them as groups. Under this scenario, urban cores presented themselves as places of political representativeness, linking the region to the capital of S?o Paulo, while converting it in a metropolis. This administratively fragmented cultural landscape between S?o Paulo and Minas Gerais territories was kept until late 19th century and the industrialization process, that began during the 20th century, was a milestone on the frontier definitions. / Esta tese se apoia na leitura da paisagem como estrutura de an?lise, e retoma a discuss?o sobre o processo de urbaniza??o brasileiro, buscando demonstrar que na din?mica existente entre o territ?rio administrativo e o territ?rio das viv?ncias existiram momentos de intersec??es demarcados pela pr?pria rede urbana. Se por um lado a vivencias, os v?nculos e os la?os afetivos entre indiv?duos e a terra fomentaram a consolida??o de estruturas de organiza??o pertinentes ao meio no qual estava inserido, por outro, o processo de funda??o de novas vilas e freguesias correspondeu ? logica dos dom?nios territoriais administrativos que avan?ava sobre o sert?o. Entre estas duas l?gicas de compreens?o territorial verificava-se a imprecis?o entre seus contornos, aproxima??es e distanciamento que dinamizaram a Paisagem Mogiana. Dela participaram fragmentos de uma rede de caminhos e bairros dispersos preexistentes, por onde circulavam diferentes entes e influ?ncias dilu?das. Esta paisagem culturalmente multifacetada fomentou o forjar de uma no??o de urbano compat?vel ao modus operandi existente no sert?o. Como camadas sobrepostas, verificam-se momentos de intersec??es e distanciamentos marcados pelos encontros, conflitos, di?logos, resist?ncias e ressignifica??es da pr?pria paisagem e da rede. A n?o compatibiliza??o imediata com um modelo urbanizador externo converte este processo em algo peculiar, condizente com a cultura local e distanciado do conceito de belle ?poque. Esta urbanidade regionalista guardava consigo tra?os culturais r?sticos, que justificavam a sua espacialidade e a forma de organiza??o da sociedade em torno de comunidades, onde a produ??o e a genealogia os definiam enquanto grupo. Neste cen?rio, os n?cleos urbanos se mostravam como locais da representatividade pol?tica, interligando a regi?o ? capital paulista, ao passo que a convertia em metr?pole. A paisagem cultural que ao mesmo tempo era fragmentada administrativamente entre territ?rio paulista e territ?rio mineiro se manteve assim at? finais do s?culo XIX, sendo o processo de industrializa??o iniciado no s?culo XX um marco na defini??o das fronteiras.
