Caracterização metamórfica do Greenstone Belt de Guarinos - GO

The study area comprises Guarinos Greenstone Belt which is located in the centralwest state of Goias and has an approximate size of 280 km2. The present work has as main objective to characterize the metamorphism of the greenstone belt and the relationship between the tectonic events and the metamorphism. For the execution of the work we used data collected in the course Geological Mapping of Crystalline Area of the geology course of UNESP, classes 2009 and 2010, the data collected by Alex Choupina Joaquim Andrade Silva in his master's thesis and the information collected in field in the study area. This compilation of data allows approximately 200 thin sections have been evaluated and allowed the construction of the metamorphic map in scale 1:125.000, also allowed the preparation of the geological map in scale 1:125.000 greestone belt, based on 1:25.000 scale maps performed by students of UNESP and the mapping conducted by Silva (2011). The study area was divided into two tectonic compartments depending on the Shear Zone Engenho Velho that longitudinally crosses study area, with direction approximately NW-SE. The west compartment is bordered by granite-gneiss complex and the east compartment, seems thicker to the south and narrows gradually towards the north and its structure is seen in general as a great monoclinal with NW-SE direction with trim to SW, this way your stack was considered as a package of rocks at the base and metaultramafic metamafic the top, with a second package in tectonic contact, which is composed of detrital and chemical metasedimentary rocks. The east compartment is represented by the intrusion of a large granitic body surrounded by amphibolites and metasediments, is bounded on the east by a granite-gneiss complexes through thrust fault, and is bounded on the west by the other compartment. The structure of the compartment is seen as a major axis oriented roughly... (Completo abstract click electronic access below)

Levantamento estrutural da porção norte do Greenstone Belt do rio Itapicuru e dos Alvos Encantado e C1W, Bahia

The study area is located in the geological context of the northern portion of the Rio Itapicuru Greenstone Belt (GBRI), located northeast of the São Francisco Craton, Bahia State. The GBRI is known for its great economic potential for gold mineralization, looking south at Fazenda Brasileiro Mine and North Mine Maria Preta, is situated in the study área. The structural pattern of the northern portion of the Greenstone, theme of this work, is of great importance to understand the mineralization present. To characterize the structural model three geologic sections (scale 1:25000) were made with NW-SE and EW directions and detailing two mineralized targets, Encantado, located northwest of the area, near the city of Nordestina, and C1W, located near Itapicuru River, west of the Maria Preta mine. Thus, field work and petrographic analysis were conducted, that allow to indicate the existence of two structural domains characterized by the existence of a main foliation, low angle dipping main foliation and another with high dip angle, both with NW, moreover, folds occur in the area Dn-1 and post-Dn folds. Dn-1 folds are observed less frequently but they occur mainly forming an oblique foliation and the Sn is present in porphyroblasts observed in petrographic analysis, whereas in relation to the folds post Dn, there are more than one type of folding in area, which differ by the orientation of their axis, a post Dn NS and EW Dn another post. Moreover, two areas of metamorphic green schist (biotite zone) and medium amphibolite, which are directly related to the structural domains found

Auxílio do geoprocessamento para a geração do mapa de suscetibilidade à erosão: o caso do córrego Mandu, Rio Claro/SP

The mining of sand, currently, is essential for urban growth, by providing input for the building industry. The consequences of this mining activity to environmental triggers may be severe and irreversible. Among the major impacts caused by sand mining the riparian vegetation removal is detached. The riparian vegetation is essential for balance and maintaining the local ecosystem. For all that had been shown, is possible to verify the importance of environmental studies in areas wich there are mining. This study aimed specially to assess environmental impacts triggered by a mining, located near the headwaters of the stream Mandu, situated in Ajapi, District of Rio Claro-SP. For this purpose, we used remote sensing techniques and GIS to produce thematic maps of slope, pedology, geology, land use and occupation of the soil, and riparian vegetation, using the capabilities of GIS / ArcGIS. The slope map was based on data from the Cartographic IGC 1979, scale 1:10,000. For the production of pedological and geological maps were used Semi-Detailed soil survey of the state of São Paulo, 1981 (1:100,000) and the Geological Map of Zaine (1994), scale 1:50,000, respectively. Since the maps of Use and Land Occupation and Riparian Forest were obtained by visual interpretation of the image of CBERS 2010 following the merger between the HRC and CCD images. From these mappings, and through multi-criteria analysis, map of susceptibility to erosion was made, which supported the environmental assessment of the studied area, indicating susceptible and unsuitable areas for the deployment of economic activities and urban sprawl. This study serves as a model can be replicated in other watersheds, assisting in the proper use planning and land use, aiming at the rational use of natural resources

Análise da dinâmica do uso da terra e sua interferência em enchentes na área urbana do município de Americana (SP)

Due to an intense process of population growth and urban density in Americana (SP), mainly due to the development of the local textile industry after 1970, there was, concomitant to the occupation of the margin of rivers and streams, soil sealing that increased the level of superficial runoff, triggering frequent floods. Based on the analysis of these processes we investigate the conditions of one densely urbanized area of the county, the Córrego do Parque, in three time series, 1977, 1996 and 2008. Taking as the starting the characterization and spatial distribution of landscape physiography, we prepared thematic letters and synthetic maps digital scale 1:10,000 from photointerpretation of aeroframes. The thematic maps were produced by scanning with subsequent edition using the software Auto-Cad Map. Checking the data and of geographic coordinates with GPS (Global Positioning System). Regarding land use classes, we used the description of the Soil Conservation Service (1975) which allowed us to get the Curve Number parameter, which will be used in hydrologic modeling for verification of flooding (Tucci, 1989). For the process of hydrologic modeling, we used models based on Methodology Object Oriented Modeling Applied to Water Resource Systems, Viegas Filho (1999), using the computer program called IPHS1, which uses models of the Soil Conservation Service (SCS , 2004), for conversion of rainfall-runoff and the spread of excessive rain. The results indicate that increased waterproofing generated by the change in use and occupation over the past decades promoted the increased surface runoff and drainage system overload, increasing the intensity of floods

Desenvolvimento de conexões hidráulicas: aplicação em sistemas de basculamento de cabines de caminhões no mercado brasileiro

The main goal of this thesis is to describe in details the development and manufacturing of hydraulic fittings for application in truck's cabin tilting lines, covering all of the pre-project, drawing, quotation and supplying processes. This development was planned due to Eaton Corporation - Hydraulics Group's interest in competing on this market with this kind of application. Company's standard procedures were executed until the final supplying stage could be reached. Moreover, the year in which this project was conducted was ruled by a crisis in the automotive segment and new opportunities had to be pursued and developed. Eaton's USA, India and China (facilities located in Aurora, Pune and Shanghai, respectively) engineering team offered all the support in order for this project to come true. As a result there are new part numbers in the company's portfolio, which now offers new fittings and a new type of adapter that was unknown prior to the project. This way Eaton has conquered even more space with this cabin tilting application and the customers (OEMs) have an alternative and homologated supplier to purchase from. Financially speaking, the project's sales income may vary from US$800,000.00 to US$1,300,000.00 worth during the following supplying years

Epithelial-mesenchymal transition occurs in preneoplastic and neoplastic lesions of canine prostate

Background: The epithelial-mesenchymal transition (EMT) is an essential process in the tumor progression and metastasis. In human prostate carcinoma (PCa), the upregulation of cytokeratin and E-cadherin and down-regulation of vimentin have been associated with aggressive phenotype and poor prognosis. Due to the importance of canine cancer model it was evaluated the immunoexpression of AE1/AE3, E-cadherin and vimentin in canine prostatic lesions. Patients and Methods: A total of 75 prostatic tissues formalin-fixed paraffin embedded from dogs was selected: 10 normal prostatic tissues, 20 benign prostatic hyperplasia (BPH), 25 proliferative inflammatory atrophy (PIA) and 20 PCa. AE1/AE3 was detected with a monoclonal antibody (Invitrogen, 180132) at a 1:300 dilution, applied for 45 min at room temperature (RT). The antibody against Vimentin (V9, Invitrogen) and E-cadherin (NCH-38, Dako cytomatiomn) were monoclonal mouse antibodies, used at a 1:300 and 1:200, respectively, for 45 min at RT. The immunolabelling was performed by a polymer method (Histofine, Nichirei Biosciences,). A negative control was performed for all antibodies by omitting the primary antibody and substituting with Tris-buffered saline. The percentage of C-MYC, E-cadherin, and p63- positive cells per lesion was evaluated according to Prowatke et al. (2007). The samples were scored separately according to staining intensity and graded semi-quantitatively as negative, weakly positive, moderately positive, and strongly positive. The score was done in one 400 magnification field, considering only the lesion, since this was done in a TMA core of 1 mm. For statistical analyses, the immunostaining classifications were reduced to two categories: negative and positive. The negative category included negative and weakly positive staining. Chi-square or Fisher exact test was used to determine the association between the categorical variables. Results: All prostatic normal and BPH tissue were positive for cytokeratin, E-cadherin and negative for vimentin. Similarly, all PIA samples were positive for AE1/AE3. From those samples, 48% (12/25) were also positive for vimentin. 55% of PCa (11/25) was positive for vimentin and among these samples 75% (6/11) was also positive for AE1/AE3 and 45% (5/11) was negative for AE1/AE3. PIA and PCa presented a higher number of vimentin positive cells when compared with normal tissue (p=0.032). E-cadherin expression had no statistical difference among diagnosis groups, but we found a higher number of positive cases, with more than 51% of positive immunostaining in BPH and PIA (81.25% and 78.60% of the cases, respectively) than in PCa (55.55%). Conclusion: The carcinogenesis process regarding prostatic epithelial cells in dogs showed higher vimentin protein expression associated with concomitant loss of the cytokeratin and E-cadherin, similar in humans.

Morphology of ileal and jejunal pouches used as rectal substitutes

PURPOSE: Our aim was to determine whether the mucosa of a canine jejunal pouch used as a rectal substitute after proctocolectomy retains its morphologic features better than the mucosa of a canine ileal pouch so used. METHODS: Among ten dogs that underwent proctocolectomy, five had a jejunal pouch-distal rectal anastomosis and five an ileal pouch-distal rectal anastomosis. After six months, the animals were killed, the intestinal pouches and portions of unaltered distal ileum were removed, and a blinded, mucosal morphometric analysis was performed. RESULTS: The mucosa of the jejunal pouches had an overall thickness (mean ± standard deviation, anterior and posterior walls, 1,300 ± 140 μm), villous height (286 ± 46 μm), and crypt depth (790 ± 77 μm) greater than that of the ileal pouches (920 ± 170, 208 ± 47, and 530 ± 130 μm, respectively; P < 0.05). Moreover, the mucosal thickness of the jejunal pouches was similar to that of the distal ileum proximal to the pouch (1,200 ± 200 μm; P > 0.05), whereas the mucosal thickness of the ileal pouch was thinner (P < 0.05). CONCLUSIONS: The jejunal mucosa retains its major morphometric features when the jejunum is used as a rectal substitute after proctocolectomy. In contrast, the ileal mucosa atrophies when the ileum is so used.

Análise da suscetibilidade a corridas de massa aplicada a dutovias: estudo de caso na bacia do Ribeirão do Roque

This scientific research aimed at to analyse the susceptibility to debris flow of the watershed of Ribeirão do Roque (SP), focusing on the upstream areas of OSBRA pipeline. This is because, mass flow can cause damage to pipes, mainly due to conditioning hydro erosion of the land in the drainage crossings, including the undermining the banks of streams. Firstly, It was conducted a literature review, aiming to identify and understand the principal characteristics and conditions of debris flow. Secondly, the physical and anthropic factors and their respective weights of influence were selected and used to determine the mass flow susceptibility. It was selected the following physical factors: type and thickness of rocks, soil and unconsolidated materials; textural density; amplitude relief; relief slope; shaped valley; and shape of slopes. Such factors are present in the physiographic subdivision map of the study area. In addition, the anthropic attributes correspond to the classes contained in the land use map. Therefore, the physical and anthropic factors were integrated through the multi-criteria analysis in a GIS environment, generating a total susceptibility map of debris flow on the scale 1:50,000. The results showed that a significative part of the study area was classified as average susceptibility. However, it was identified areas with high susceptibility in the region in which the pipe cross the Ribeirão do Roque. Moreover, at which point the river presents a closed valley and a meander shape, without a fluvial plain that would be useful to attenuate the development of the process. Consequently, if a mass flow begins in any of these most susceptible regions located upstream of the pipe, the chances that the process develops by the river and causes the excavations of his bed are quite large. However, the pipelines cross these critical areas directly on the rock (diabase), which provides additional protection against possible ...
