Pré-sal e o novo marco regulatório: um estudo sobre o fundo social

This work intends to discuss about the current happenings in oil sector, and how the recent discovery of huge oil reserves on the layer known as Pre-Sal can positively transform in the socioeconomic context, the country. The impact of this huge quantity of natural resources it depends on the legislative policies adopted for the exploration and production (E & P) in the Pre-Salt layer, and the way in which laws are imposed for distribution of such resources. Therefore, it is made a shortly background of the laws from oil exploration, production and distribution, since the monopoly of Petrobras, to nowadays. To this end, an analysis is performed about the Oil Law, and about the possible legislative changes with the new Regulatory Framework. This monograph attempts to prove, based on historical data, socioeconomic facts, and international experiences, using either comparative statistical, that with the discovery in the Pre-Salt area, the best way to optimize the use of these resources, mainly the reduction of social inequality and economic contrasts, a legacy from colonization, would directly those recipes to a National Development Fund, the Social Fund, established by law for the new Regulatory Framework

Análise comparativa do mercado imobiliário em Cidades Médias: a oferta de apartamentos, casas e terrenos urbanos em Campina Grande – PB, Mossoró – RN e Passo Fundo – RS

This presente monograph propose the analysis and discussion of the production of urban space and the processes of their structuring intraurbana from the dynamics of the real estate market into three Medium-sized Cities, Campina Grande - PB, Mossoró - RN and Passo Fundo - RS, whereas the various agents producing this space, in a comparative perspective. From this urban dynamic search to analyze the processes and relations present in these spaces, which are important for its production. From the compilation of real estate advertisements in local newspapers, are analyzed offerings of urban land, houses and apartments in each one of these cities by highlighting their locations and differentiated prices. Thus, working with data from real estate ads from the period 1995 - 2010 and a comparative perspective of the characteristics of real estate markets of three medium-sized cities, it tried to apprehend processes that are common between them and other individuals, to each one. Therefore the comparative analysis developed in this monograph sought to verify whether there are similarities between the cities in relation to the trends of concentration/spatial dispersion of bids and movements throughout time, in addition to a further intensification of the activities of real estate agents in face of such trends and offerings. In addition, we sought to remove a set of problematization that allow them to understand with more acute, in this set of medium cities of Brazilian urban network, processes of change that is already being discussed in the recent period by ReCiMe.

Imunocastração e ractopamina na qualidade de lombos suínos processados com sal e tripolifosfato

The objective of this work was to evaluate the effect of immunocastration and supplementation with ractopamine in the quality of pork loin enhanced with salt and sodium tripolyphosphate. Treatments consisted of the sexual condition of the swine (females, physically castrated and immunocastrated males) and supplementation or not with ractopamine in finishing diet. The loins subjected to the enhancement with sodium tripolyphosphate and salt were evaluated as to physical-chemical, microbiological, and sensory parameters. There was no interaction between sexual condition and ractopamine on fresh pork loin characteristics. The addition of ractopamine in the diet increased the shear force in fresh loins. There was also no effect of sexual condition nor of ractopamine in purge loss and loin protein content. Loins of immunocastrated animals had less weight loss by cooking, whereas loins of animals non-supplemented with ractopamine showed higher moisture than those supplemented. Enhancement decreases the shear force of the cuts, which was lower in the immunocastrated animals without ractopamine supplementation. Immunocastration provided pork loins with high a* and L* values. Differences in the appearance and texture of pork loins, regardless of sexual condition and ractopamine, are not perceived by consumers, showing that enhancement standardizes the cuts.

Análise das relações entre parâmetros geolétricos e vazões para o aquífero livre de Caçapava do Sul - RS

The geophysical methods may be employed in aquifer system studies, as determination of groundwater level, soil/rock contact, beyond estimative of the aquifer thickness horizon. The geoeletric methods are particularly relevant in evaluations of the oilfields systems, due to directs relations between porosity and electrical resistivity, which allow inferences about oil and gas production. The indirect estimative of the productions in free aquifers system is something complex before of the diverse variables responsible for factors or physical phenomena, as clays minerals, which conditioned the physical parameters by electric geophysical methods. This paper present analyzed correlation among electrical resistivity, chargeability and direct measure flow in shallow wells, for determination of statistical relationships between parameters and evaluation of the geological constraints evolved. The study count with the 23 shallow wells located in free aquifer, constituted by alteration materials of the granites localized in Caçapava do Sul (RS). The geophysical data are acquired by vertical electric sounding in Schlumberger array. The correlations between electrical resistivity and flow, chargeability and flow, thickness of the soil/saprolite and flow indicated relationships between physical and hydrogeologic parameters, with variations conditioned by factors as porosity, permeability, besides intrinsic geological heterogeneities such soil variable thickness and rock fragments with several alteration degrees.

Caracterização geofísica no Gabro Santa Catarina, São Sepé (RS)

Geophysical methods are widely used in mineral exploration for several types of mineral deposits. When combined with direct studies as geochemistry, a substantial increase in the probability of ore discovery is possible in mineral exploration activities. Electrical geophysical methods are particularly promising in studies related to the search of sulphides due to the contrast of physical properties electric resistivity and chargeability. This paper presents the results obtained from the application of Resistivity (DC) and Induced Polarization methods, through the electrical profiling technique, aiming at evaluating the potential mineral of a gabbro intruded in a metasedimentary sequence, in an area where several occurrences of gold and copper were described. This gabbro is ranked on the Basic-Ultrabasic stratiform bodies, which gather peridotites, gabbros, and layered anortosites. Three radial lines of electrical profiling were performed, spaced of 60° and crossing at the area center, with readings of electric resistivity and chargeability in Wenner-Schlumberger array. The association of low resistivity and high chargeability areas has allowed defining potentially mineralized zones related to structures that condition the drainage net in the gabbro domain. Grains of gold detected through geochemical prospection of alluvial sediments dowstream from the gabbro may have originated from leaching of ores deposited in fractures through the action of river waters within the gabbro domain, possibly consisting of sulphides and gold.

Determinação de atividade de água, umidade e sal em peixes salgados e secos importados

Brazil is a major importer in the world salted fish trade. The sale of these products must meet the established standards, based mainly on the salt and moisture levels. The aim of this study was to analyze the salt and moisture levels in imported Atlantic cod and Pacific cod, and in the dried salted fish Ling, Zarbo and Saithe, which are not classified as cod since they do not belong to the genus Gadus. The water activity was also analyzed, which could be a useful parameter to determine the quality of salted fish.The results showed that the legal limits for salt were much lower than the values found in the analyses. The moisture contents established for the category of salted fish, as determined by the Portuguese legislation, were more reliable. We suggest the inclusion of the water activity as a parameter for the evaluation of these products.
