The opal of the municipality of Pedro II, in the state of Piauí, is of noble quality in Brazil and its reserves, together with the Australian reserves, form the only deposits of opal of importance in the planet. The research carried out an interdisciplinary dialogue between the Line of research in Languages and Technologies with the research line Culture and Art in the Contemporaneity, where it approaches the extraction of the opal in Pedro II and its artisan production. The purpose of this work is to present a representative picture that portrays the current stage of evolution of the Pedro II opal extraction, the work with this stone, the production of jewelry, as well as the results of the designer's work and its effective and significant influence in creation and execution of these parts. This work uses bibliographical studies, field research and interviews with residents, who experience extraction, stoning and artisanal production and the influence of design in the promotion of locality and its people. It was also presented the stage of the opal extraction, its development and the need to seek improvement in all its particularities. Finally, it was observed that there is the raw material, the labor, the interest in doing, the improvement and professional qualification, the pride of the Piauí people to own in their own lands a wealth like the opal. However, it is necessary the support of federal institutions or state organs, especially so that the potential of the work developed by craftsmen and designers can be recognized, valued and marketed nationally and internationally.

A pesquisa realizou um diálogo interdisciplinar entre a linha de pesquisa Linguagens e Tecnologias com a linha de pesquisa Culturas e Artes na Contemporaneidade, onde aborda a extração da opala em Pedro II e sua produção artesanal. O objetivo da mesma é apresentar um quadro representativo que retrate o atual estágio de evolução da extração da opala de Pedro II, o trabalho com essa pedra, com a produção de joias, além dos resultados do trabalho do designer e sua influência efetiva e significativa na criação e execução dessas peças. Este trabalho utiliza estudos bibliográficos, pesquisa de campo e entrevistas com moradores, que vivenciam a extração, lapidação e produção artesanal e da influência do design, na promoção da localidade e do seu povo. Foi apresentado ainda o estágio da extração da opala, do seu desenvolvimento e a necessidade da busca de melhoria em todas as suas particularidades. Por fim, observou-se que existe a matéria-prima, a mão de obra, o interesse no fazer, o aperfeiçoamento e qualificação profissional, o orgulho do povo piauiense de possuir em terras próprias uma riqueza como a opala. No entanto, é necessário o apoio de instituições federais ou órgãos estaduais, sobretudo para que o potencial do trabalho desenvolvido pelos artesãos e designers possam ser reconhecidos, valorizados e comercializados nacionalmente e internacionalmente.

Der volle Inhalt der QuelleThis paper proposes an analysis of mineral tourism in Pedro II through the structuring of a new territorial dynamics by the Local Productive Arrangement (APL) of Opal in Pedro II - Piaui. At the begning of this arrangement in 2005, informality was predominant on the sector, generating stones smuggling, tax evasion, labor accidents and environmental impacts all over the region. This work aims to determine how the structure of the APL of Pedro II Opal helped to boost socio-economic development and especially the tourism in the city. The survey was conducted based on the case and insight observation study methodology, including steps such as analysis of administrative documents of the cluster partners, field research and interviews to verify the tourism conditions, the economic development of the municipality, work in mines, stonings and jewelry, and the positive consequences as a result of the consolidation of APL Opal Project in the region and for the players involved. Data that were collected in the field were used as a basis for analyzing the influence of APL Opal in the Pedro II tourism. But for this new activity to develop, there is a need to draw up an effective and viable project application model, taking into account not only the pros and application cons of this idea for the benefit of the population but also the scope project for local development without the loss of cultural, territorial and social identity. With this analysis, it was determined that the municipality needs a proper urban planning and tourism, as it has enough attractions to promote economic growth based on the production chain of opal

Der volle Inhalt der QuelleTissue engineering has emerged as a promising strategy for regeneration of damaged tissues, especially when stem cells are associated to biomaterials. The characteristics of adipose-derived stem cells (ADSC), which are a type of mesenchymal stem cells, makethem a tool with great therapeutic potential. Different types of biomaterials can be used as artificial substitutes of the extracellular matrix, providing a support matrix for in vitro cell culture. The present study aimed to isolate and characterize human, canine and murine ADSC, and toinvestigate the patterns of adhesion and proliferation of these cells after association with collagen-based biomaterials, open-cell poly (L-lactic acid) (OPLA) and calcium phosphate (BD Biosciences). Adipose tissue was obtained from patients undergoing elective liposuction, healthy dogs, and C57BL/6 mice, respectively. The tissue was digested with collagenase and the isolated ADSC were cultured and characterized for morphology, immunophenotype and proliferation and differentiation potential. Cells were associated to biomaterials scaffolds, for tridimensional (3D) cultivation, between passages 4 and 7. The biomaterials were divided into two groups: one was previously pre-incubated with culture medium supplemented with 10% of fetal bovine serum (pre-coating, PC), and the other was not (dry, D). Two cell concentrations were used, 104 and 5x104 cells/scaffold, and conventional cell cultures (2D) were performed to compare the rate of proliferation in 3D x 2D systems. The rate of adhesion was assessed by counting the non-adhered cells after 3-hour incubation with the scaffolds. The proliferation index of ADSC cultivated under 2D conditions was measured after 3-day incubation by the MTT assay. The results show that ADSC from the three species present features characteristic of mesenchymal stem cells, and adhere more to scaffolds not submitted to pre-incubation (D),at the concentration of 5x104 cells/scaffold. Human ADSC showed higher proliferation index in 2D condition than in the 3D condition, contrary to canine and murine ADSC. Together, these results indicate that association of ADSCfrom different species to biomaterials is feasible and may be exploited for clinical applications.

Der volle Inhalt der QuelleIn the state of Rio Grande do Sul, the precious stones mines are distributed in two main regions: in the Mining District of South Amethyst (largest producer of amethyst) and the Mining District of the Salto Jacuí (largest producer of agate). In these two districts Geodis miners are exploited, partially or completely filled by intercalated layers of agate, clear quartz, amethyst, opal and calcite. The extraction process of Geodis generates large amounts of waste, comprising both the rock of the ore carrier as well as of low quality ore. In the municipality of Soledade focus the main company to benefit from trade and gemological materials used in Rio Grande do Sul. However, most of the objects produced aimed at the export is repeated in various industries benefit without apparent difference. The opal found in the mines of the Salto Jacuí appears in many colors. The white opal is the most common and is not valued, thus generating significant amount of waste. Through this study, that aims to establish a methodology for processing by the CNC machining waste of opal and white agate from the Mining District of the Salto Jacuí, a great value was added for design and technology. Whereas the most currently used in industries for agate, dyeing and cut into plates, are not applied to the opal, one can say that the introduction of CNC machining in this sector can assist in the exploitation of such material, to modify and value them as objects of adornment in the form of camafeus. The methodology used for this research consisted of steps of identifying locations for extraction of opal and white agate the state, evaluate the procedures used for further processing of these materials, study and analysis of the material by specific techniques, testing of CNC machining, analysis of cutters and materials used after the processes involved in machining and product development. Were conducted nine tests of machining and the subsequent analysis, identifying the results that, with the cutters suitable for the wear (larger diameter) or finishing (minor diameter of tip), when used together with parameters and machining strategies for well-defined, are sufficient to achieve the goal defined in this study.

Na área de Xambioá - São Geraldo do Araguaia, situada na porção setentrional do Cinturão Araguaia, ocorrem veios com opala, com ametista, com quartzo tricolor, com quartzo rutilado e com clorita, de caráter pegmatítico e hidrotermal, que pelo seu interesse gemológico foram investigados em detalhe. O veio com opala, de maior relevância, encontra-se alojado nas rochas metassedimentares da Formação Xambioá e apresenta um zoneamento bem definido e uma textura brechóide. As zonas de borda são constituídas por quartzo leitoso, enquanto que as partes internas compõem-se de ônix e opala jaspe (C-T) cortado por vênulas de opala C-T e opala A. No quartzo da borda foram identificados fluidos dos sistemas H2O-CO2- NaCl e H2O-KCl-NaCl, de alta salinidade ( equivalente a >26% em peso de NaCl), enquanto que na zona intermediária foram encontrados fluidos do sistema H2O-FeCl2-NaCl, de baixa salinidade ( equivalente a 0,88 a 3,71% em peso de NaCl). Foram determinadas Th de 232 a 310° C no quartzo da borda, e de 110 a 145 ° C no quartzo da zona intermediária. Estes dados sugerem, para o quartzo da borda e da zona intermediária, uma origem relacionada ao metamorfismo regional e/ ou magnetismo do Ciclo Brasiliano, com uma contribuição crescente com o tempo, de águas meteóricas. O ônix e a opala C-T teriam sido originados de hidrotermalismo mais tardio, apresentando forte participação de fluidos meteóricos e possivelmente decorrentes da reativação de antigas fraturas durante o Paleozóico e/ou Mesozóico. Uma origem supergenica recente parece ser a mais provável para a opala A. O veio com ametista encontra-se alojado no corpo granitóide da Serra da Ametista, possui caráter pegmatóide e é constituído por quartzo, ametista, microclina, oligoclásio, muscovita e biotita. Fluidos do sistema H2O-KCl-NaCl são encontrados no quartzo do veio e na ametista. No quartzo veio esses fluidos têm salinidade equivalente a 18 e 20,75%, e na ametista entre 12,73 e 18,22% em peso de NaCl. A Th situa-se entre 190 e 248,5 ° C no quartzo e entre 155 e 200° C na ametista. Esses fluidos devem ter origem magmática e estar relacionados com a fase tardia de resfriamento do corpo granitóide da Serra da Ametista. As idades Rb-Sr determinadas em pares de minerais (muscovita-microclina e muscovita-oligoclásio) variam entre 390 e 430 Ma., sendo mais jovens que a provável idade Brasiliana de formação deste veio, o que sugere a reabertura parcial do sistema Rb-Sr na ocasião de reativações tectônicas posteriores. O quartzo tricolor ocorre na forma de cristais zonados, localizados nas porções mais internas de veios de quartzo alojados em metarcósios e metarenitos da Formação Pequizeiro. A presença de rutilo vermelho, pirita e melanterita confere à extremidade dos cristais uma coloração vermelha clara a marrom amarelada. Na porção basal, a bicoloração lilás-amarela é dada pela presença de traços de ferro, alumínio, potássio e sódio. Na zona de borda do veio, o quartzo contém fluidos do sistema H2O-CaCl2-NaCl, de salinidade elevada ( equivalente a 20,60 a> 23,18% em peso de NaCl) e Th entre 488 e 492° C. No quartzo tricolor foram identificados fluidos dos sistemas H2O-CaCl2-NaCl e H2O-Fe Cl2-NaCl, na porção basal, e H2O-FeCl2-NaCl,na extremidade dos cristais. A salinidade dos fluidos da porção intermediaria dos cristais, a salinidade varia entre 11,34 e 12,39% equivalente em peso de NaCl enquanto Th encontra-se entre 272 e 305° C. Nas extremidades dos cristais, observou-se uma diminuição da salinidade (equivalente a 8,65 a 10,10% em peso de NaCl) acompanhada por uma diminuição da Th, que na porção basal é maior que 485°C e nas porções superiores dos cristais varia entre 267 e 299,5° C. As pressões mínimas de aprisionamento dos fluidos,no quartzo tricolor, situam-se em geral entre 400 e 600 bars. O estudo por MEV do quartzo tricolor mostrou a presença de inclusões de teorita e de mercúrio metálico na porção basal; de pirita, cinábrio e zircão na porção intermediaria; e de pirita, melanterita, anidrita e barita na extremidade dos cristais. A gênese desses veios estaria relacionada à evolução do magnetismo regional, não se descartando uma participação da fase final do metamorfismo, além de uma contribuição de águas meteóricas, sobretudo na formação das porções superiores dos cristais de quartzo tricolor. Os veios com quartzo rutilado e com clorita encontra-se alojados nos micaxistos e quartzitos do Grupo Estrondo. São constituídos por quartzo hialino, rutilo, clorita, hematita especular e magnetita. Fluidos do sistema H2O-KCl-NaCl forma identificados tanto no quartzo das zonas de borda, como no quartzo rutilado e com clorita das partes mais internas dos veios. A salinidade dos fluidos é elevada nas zonas de borda ( equivalente a 18,80 a 23,18% em peso de NaCl) e baixa na zona interna ( equivalente a 4,34 a 5,26% em peso de NaCl) enquanto que Th situa-se entre 293 e 345°C e entre 136,5 e 198,9°C, respectivamente. Acredita-se que os fluidos que geraram as zonas de borda tinham origem magmática e/ou metamórfica. No entanto, uma expressiva contribuição meteórica é admitida na formação das porções mais internas dos veios. Os dados obtidos sugerem que a formação dos sistemas de veios estudados resultou principalmente de movimentos distensivos e do hidrotermalismo que marcaram a fase final da estruturação do Cinturão Araguaia e sucederam ao metamorfismo regional e à conseqüente granitogênese. Independentemente da natureza do sistema aquoso, os fluidos geradores do quartzo de origem magmática e /ou metamórfica profunda apresentam, de inicio, uma alta salinidade e uma temperatura média a elevada. Seguiu-se uma forte diminuição da salinidade e da temperatura ( abaixo de 200° C), devido, provavelmente, a uma participação crescente de águas meteóricas. Posteriormente, fases de reativação tectônica no Paleozóico e/ou Mesozóico forma responsáveis pela mobilização e injeção de soluções ricas em sílica geradas em profundidade e pela precipitação da sílica na forma de ônix, de opala jaspe e de opala C-T. Mais recentemente a opala de tipo A se formou em condições supergênicas.
In the Xambioá-São Geraldo do Araguaia region, located in the northern segment of the Araguaia belt, pegmatitic and hydrothermal quartz veins with opal, amethyst, three colored quartz, and with rutile and chlorite occur. The genesis of these veins has been investigated due to their gemmological interest. The most important opal — bearing quartz vein is hosted by metasedimentary rocks of the Xambioá Formation, and presents a rough zoning in addition to a brecciated texture. The outer zone of the vein consists of milky quartz, while the inner zone is composed of onyx, jasper opal (C-T) cut by small veins of C-T opa! and A opal. High salinity fluids of H2O-0O2-NaCl and H20-KCl-NaCl systems (> 26 wt% of NaCl equiv.) have been found in the outer zone quartz, while in the intermediate zone low salinity fluids of the system H20-FeCl2-NaCl (0,88 to 3,71 wt% o NaCl equiv.) were observed. Th ranges from 232 to 310°C and from 110 to 145°C for the quartz of the outer and intermediate portions, respectively. These data, along with the opal metastability suggest that the quartz of the outer zone may be related to the regional metamorphism of Brasiliano age that affected the Araguaia belt. They also suggest a contribution of meteoric water to the formation to both the jasper opal and the C-T opal, as well as a supergenic origin to the A opal. The inner portions of these veins may have been formed by the reactivation of older fractures during the Paleozoic and/or Mesozoic. The vein with amethyst in emplaced into the granitoid body of Serra da Ametista. It is pegmatitic in nature and is composed of quartz, amethyst, microcline, oligoclase, muscovite, and biotite. Fluids of the system F120- KC1-NaCl are found in both quartz and amethyst. In quartz, the salinity of these fluids ranges from 18,95 to 20,75 wt°/.9 of NaCl equiv., and in amethyst from 12,73 to 18,00 wt% NaCl equiv. Th ranges from 190 to 248,5°C in quartz, and from 155 to 200°C in amethyst. These fluids might have had a magmatic origin and be related to the late cooling phase of the Serra da Ametista granitic body. Rb-Sr ages in pairs of minerais (muscovite-microchne and muscovite-oligoclase) range between 390 and 430 Ma. These ages are younger than the probable Brasiliano age of the vein and suggest a partial resetting of the Rb-Sr system due to subsequent tectonic reactivations. The three colored quartz occurs as zoned crystals in the inner parts of quartz veins emplaced into metarkoses and metasandstones of the Pequizeiro Formation. Inclusivas ofred rutile,pyrite and melanterite in the upper parts of the quartz crystals give them the light red to yellowish brown color. In the lower portion, the purple-yellow dual coloration is given by the presence of iron, aluminum, potassium and sodium. In the outer portion of the studied veie, the quartz presents high salinity fluids of the system H20-CaC12-NaCl (20,60 to higher than 23,18 wt°/0 of NaCl), and Th ranging from 488 to 492°C. Fluids of the systems H20- CaC12-NaCl and H20-FeC12-NaCl were identified in the lower portion of the three colored quartz crystals, and of the system H20-FeCl2-NaCl in the upper portions. The salinity of the fluids in the lower portions ranges from 13,83 to 17,34 and from 17,96 to higher than 23,18 wt% of NaCl, respectively. In the upper portions of the crystals, the salinity decreases. Th, which is higher than 485°C in the lower portions decreases to values between 272 and 305°C in the upper portions. A MEV study in the three colored quartz showed inclusions of thorite, metallic mercury in the basal portion; pyrite, cinnabar, and zircon in the intermediate portion; and pyrite, melanterite, anhydrite, and barite in the upper portion. The origin of these veins may be related to the regional magmatism in the Araguaia belt, but a possible influence of the final phases of the regional metamorphism cannot be ruled out. Contribution of meteoric water, mainly to the upper portions of the three colored quartz crystals, has also to be considered. The quartz veins with rutile and chlorite are hosted by the mica schists and quartzite of the Estrondo Group. They are composed by hyaline quartz crystals, rutile, chlorite, specular hematite, and magnetite. Fluids of the system H20-1CCI-NaCl, were identified in the quartz of the outer parts of the veie, as well as in the quartz with rutile and chlorite of the inner parts. However, the salinity of these fluids is higher in the quartz of the outer parts (18.80 to higher than 23.18 wt% of NaCl) than in the quartz with rutile and chlorite (4.34 a 5.26 wt% of NaCl). Th ranges from 293 to 345°C in the quartz of the outer zone, and from 136.54 to 198.9°C in the quartz with rutile and chlorite. The outer parts of the veie were possibly generated by fluids of magmatic and/or metamorphic origin. However, a considerai* contribution of meteoric waters is considered for the formation of the inner parts of the veins. The data suggest that the quartz veins systems are related to extensional tectonic and to hydrothermal events which took place in the late stages of structural development of the Araguaia belt, following the regional metamorphism and the consequent granitogenesis. In spite of the nature of the aqueous system, the magmatic and/or deep metamorphic fluids that generated the quartz veias show, initially, high salinity and medium to high temperature. Probably due to the increasing contribution of meteoric waters, both the salinity and temperatures (lower than 200° C) decreased. Later, tectonic reactivations during the Paleozoic and/or Mesozoic were responsible for migration and injection of silica bearing solutions, generated at depth, and by precipitation of silica as onix, jasper opal and opal C-T. More recently, opal A was formed in supergenic conditions.

Der volle Inhalt der QuelleThick humic A horizons (umbric epipedons) may be found in several Brazilian Latosols (well drained Oxisols - Lh). This dark colored horizon (Ah) is frequently more than 1m thick and has a large stock of soil organic matter (SOM) and differ from nearby Latosols without an Ah and on younger surfaces and do not conform with present climate and vegetation. Several hypothesis about their genesis had been raised but without a good pedogenetic understanding. This thesis aims to define environmental variables responsible for their formation. Several pedons were examined through their morphology and landscape position, and their soil materials were studied by geochemistry methods and paleoenviromental evidence by C isotope and phytolith assemblages. First, a bibliographic survey was performed to choose a set of 39 profiles were chosen to be studied on a data set where 11 noted chemical and granulometric attributes and one environmental variable were submitted to multivariate statistic analysis in order to group then according to similarities. Three groups were defined: G1 - Brown and Red Latosols from summit surfaces of the Brazilian Southern uplands (with the highest clay, organic carbon and iron oxide values, but with thinner epipedons than the others groups). G2 - Yellow-Red and Yellow Latosols, predominantly found in summit positions, remnant ancient geomorphic surfaces from the Southeast region and associated with the vegetation adapted to high altitudinal tropical climate. G3 - Red Yellow and Yellow Latosols from the Brazilian Southeastern piedmont upland surfaces and Northeastern coastal tablelands (with the thickest umbric epipedons, loamy to clayey textures, lower carbon contents, and a kaolinitic mineralogy). From this analysis 30 Lh representative pedons were field sampled to be characterized, including total Zr and Ti contents, stable carbon isotopes (13C, 14C) and phytolith analysis, in order to better understand paleo-environmental conditions they were subjected. For the phytolith extraction laboratory procedure were adapted in order to better separate and clean then from oxidic coatings. The SOM isotope data and phytolith assemblages indicated that these Ah were formed under a less dense vegetation than the present one: a probably mixture of C3 and C4 (~-22) plants, with more contribution of the C3 in the Southeast and Northeast regions, a more open (~-16, grassy), vegetation (with contribution of C4 plants) in the middle to medium Holocene indicating the presence of a drier climate in the Southern region. From the Late Holocene a more 13C depleted values (~-25) was observed, suggesting the expansion of the tropical and subtropical forests in this region, probably associate to a humid and warm climate in the Southeast and Northeast regions, and humid and cold in the Southern region. The combination of climate and vegetation late, parent material, and stability relief have played a major role in the geographic and formation of the parent material and pedogenetic horizons of these Lh, and thus they should be considered as polygenetic soils. The humic horizons constitute an important register of Holocene climate change and that they should be considered as relic paleosoils.
