The Itararé Group is the record of one of the most significant glaciation events of the Gondwana. Of neocarboniferous-eopermian age, this unit has facies associations interpreted as resulted from shallow marine settings with glacial and deglacial water influence. The role of glaciers on the tectonic-sedimentary processes of the Itararé Group is striking, as typical facies such as diamictites, tilites, shales and rhythmites with dropstones are generated, besides the existence of glacially striated and polished surfaces. This work had as main goal to contribute to the geological knowledge of the Itararé Group in the central eastern portion of São Paulo State, using as basis outcrops from Itu, Salto and Porto Feliz, and also pertinent bibliographic data and well profiles located in the surrounding areas. About the stratigraphic framework, genetic association and paleogeography of these deposits, this work concludes that the area studied comprises the basal section of the Itararé Group. The stacking of the facies recognized during the field work begins with the striated and polished surfaces of the basement, described in Salto, superposed by tilites and diamictites with glacial movement features. Over these are the turbidites from Itu, associated with the glacier retreat. The outcrops of Porto Feliz are at the top of this succession, with deposits generated by flows with lateral and vertical variations, sometimes with prevalence of tractive conditions, and sometimes with sediments transported largely by suspension. Paleocurrent measurements show main flow directions towards NW, the same as glacial striae, suggesting the influence of reworking of sediments by the meltwater during deglacial periods

This work aims to analyze data from a Natural Electric Potential landfill type ditch located in Cordeirópolis (SP). The procedure measures initially involved the assembly and installation of an apparatus cables, sensors and drain geophysical measurements and flow rate of biogas in a ditch later filled by solid waste. Biogas is a product of degradation of organic matter in waste by the action of microorganisms in an anaerobic environment. Its features high methane content in the gas potentially usable as fuel in energy generation systems or steam. The study area is characterized by clayey soil composition change from the diabase sill correlated to the event Serra Geral Formation siltstones overlapping Tatuí with groundwater level site around 50m. The cables were installed vertically in parallel with drain gas manifold, which allowed the collection of data by the technique geophysical logging every 15 days over a period of eight months. For data analysis we used four parameters in the study, the closing time of the ditch, natural electric potential, the flow velocity of biogas and rain. With the tabulated data plots were constructed for each collection day showing values in the range of the cable is in contact with waste (200 cm - 400 cm) and range of the cable in contact with the soil (600 cm - 800 cm). Subsequently graphs were generated with the period of eight months to analyze the data tabulated. A statistical correlation data, which show the influence of rainfall on the production of biogas. The results were satisfactory and demonstrated the feasibility of the research method in studies for the feasibility analysis for the capture of biogas energy

AC Biosusceptometry (ACB) is a low-cost biomagnetic tool that has been successfully applied on pharmaceutical research to evaluate performance of solid dosage forms. The aim of this work was to evaluate the Horn & Shunck method to access tablet disintegration. To evaluate the HS results was record on video a test with a objet moving in a rail with a constant velocity. The desintegration was recorded on video and ACB, which used have seven pairs of detection coils and a pair of excitation coils to mensure the magnetic ux variation. The signals were ampli ed and digitalized to create images, which were restored by Wiener lter, while the video images are converted to gray scale, both are normalized and binarized and had the optical ow estimation calculated by Horn & Schunck (HS) algorithm. All signals and images are processed and developed algorithm on Matlab. During the tests the ve tablets (500mg ferrite, 375mg excipients, compression 10 to 50 kN) were on a becker between of the ACB system and of the video system, and only touching the surface of the water. With all OF maps calculated was realized the sum of the resultants of each, to get a disintegration process resultant for each compression. Whit that was possible observed the disintegration behaves. For the compression force study the HS components of each sequence was sum, take mean and normalized for sequence's max modulo, therefore can be observed a high growing on less compression tablets. We can conclude the HS algorithm is viable to tablets disintegration data collection and whit that was possible to create a tablets disintegration analyzes protocol, which would be useful on desintegration kinetics study

In order to to research, the region of Perau, base metal mineralization, Grupo Votorantim Metals conducted a soil sampling on targets predetermined holding its chemical analysis. These reviews have been provided by the company for this work was to evaluate the potential use of these data pedogeochemical multi-element for refinement of the work of geological mapping. We selected six targets: Varginha, Salvador, Guararema Taquara Lisa and Coffin of Mendes, in the municipalities of Adrianople, Cerro Azul and Tunas do Paraná, located in Vale do Ribeira (PR). Both have about 10 km2 and situated in the geological context of the Fold Belt Terrane and the Massif de Joinville. The main rock types are present metasedimentary rocks of low to medium grade metamorphic, interspersed the amphibolites ortoderivados, both belonging to the Complex Perau, gneisses and migmatitic Complex. Applied to the geochemical data descriptive statistical techniques (variogram, kriging and histogram). From the correlation between the distributions of elements with the geological data, we could assess the potential of the proposed methodology.

In this work, it was studied the thermal and fluid dynamic behavior from theorical and experimental point of view of a blast furnace tuyere. The tuyere is responsible for the hot air insuflation into the blast furnace. The parameter used in the comparison was the difference between the cooling water inlet and outlet temperatures. There were used forced convection correlations inside circular sections with adequations for non circular sections. Based on operations dates of flux and thermal loads it was possible to model numerically the tuyere, and, since it was obtained the wall temperatures, estimate the conduction and convection resistances and the heat flux through the walls in contact with the water. The total heat fluxes from wall to water were applied to the energy conservation equation where could be estimated the theorical temperature variation. Compared to the real value, the theorical value presented a difference of 0,2 °C. Considering that the boundary conditions around the tuyere are transitories and that your channels have some rugosity irregularities we can consider the estimation method for cooling system coherent with the real operational parameters

The development of medium-sized cities in recent decade, caused, partly, by the industrial deconcentration process generated, beyond benefits, several problems for these cities population. The unplanned rapid growth of these cities, together with the capitalist model of production collaborated for the increase of socioeconomics questions in these locations. The urban mobility became one of these problems, embarrassing citizen’s lives, especially in downtown area. Therefore, the State began looking for solutions to improve urban mobility of the population, contributing to their quality of life and also to adapt the city to new market demand. In these work, we analyzed the situation of Brazilian medium-sized cities downtown area, as well as its growth process, tanking as an example the case of the city of Rio Claro – SP and it´s Public Administration proposal to improve the flow and urban mobility in a particular street in the town´s commercial centre

Studies about efficiency have gained dimension, in Brazil, since the early 90’s. Same decade that the Civil Aviation System suffers important changes in terms of regulations. Such transformations have echoed effects currently, with some significant trend for international standards. This paper focuses on one of the agents from the Brazilian Civil Aviation System, the airlines companies, which aimed on analyze and evaluate both passengers and cargo air transport, by using data envelopment analysis (DEA), during the period of 2005 to 2010. The yearbooks of ANAC, corresponding at the period from 2005 to 2010, were used as data base in this present study. The technique was applied to 14 companies, which through Stepwise process of variables validation was possible to compose a compact, but complete model, that could translate the reality of companies. This model was composed by one output, Total Income, and by four inputs, Total Costs, Total Domestic Passenger, Total Cargo and Total International Passengers. However, this approach has some flaws. Therefore in order to remedy it, it was required to apply the method Frontier Inverted, one of the alternatives proposed in the literature, which ensured an improvement in the context of efficiencies due to biggest discrimination of airlines. As a result of the DEA-BCC process, oriented by output, TAM 2005 was considered the most efficient company, however GOL and Webjet companies concentrated in 2007 their worst levels

In 2008 the United States had suffered from a financial crisis due to the real estate market, this movement affected other countries whose economy depends on the USA. Brazil suffered this crisis, but to avoid a greater turmoil in national territory the government launched some public policies to allow the market to keep working, that way allowing a cash flow more stable. One of these policies is called Inovar-Auto where automakers get benefits in form of taxes redution since some investiments are made in tecnology in Brazil made. This study does a qualitative reaserch to identify how companies are adapting to the Inovar-Auto, its dificulties and the real benefits trough colected data along these years

This work has as a central concern in analyze the causes of the still limited access of young Brazilians to public higher education in socioeconomic and cultural.In Brazil, onçy 14,4% of the young between 18 and 24 years old attend this educational level.If we consider that the public university offer just 1/4 of the vacancies, can be affirmed that this institutions are not able to attend neither 4% of the young between 18 and 24.Brazil shows,in this level of education,a lower access that most of its neighbors: Argentina(40%), Venezuela(26%), Chile(20%),Bolivia(20%).In this work were analyzed the data reports of entrance exam of Universidade Estadual Paulista (Unesp) entre 2004 e 2009,prepared by Fundaçao para o Vestibular da Universidade Estadual Paulista(Vunesp). In this analysis,can be noted the influence of some aspects socioeconomic and cultural related to possibilities os the young acces to public univercity. Stand out among these: family income,the possibility to dadicate only to studies and attend preparatory courses,as well as the parents level of education.
