    The Macae Formation (Late Albian-Turonian of the Campos Basin) is represented by a thick column of carbonate sediments whose deposition began soon after the evaporitic phase that marks the beginning of the marine occupation of the basin. The top of this interval is represented by an unconformity (Type I), indicative of a variation in the base level of the basin, on which the turbidities of the basal sequence of the Namorado Field were deposited. For a better understanding of the depositional geometry of these turbidities, the paleogeomorphology analysis demonstrated to be quite efficient. The method of work used for so was a combination among the seismic 3D visualization (VoxelGeo{sup R}), from the characterization of different physical attributes of the seismic signal, and the facies analysis of wells profiles of the referred field. The developed analysis allowed the individualization and the three-dimensional visualization of a sinuous paleochannel in the top of the interval, until then not described in previous interpretations of this depositional system. With the information coming from this study, a better understanding of the genesis of this accumulation can be reached, especially in the part regarding to the units of important economic character, represented by the turbidities deposits and whose occurrences are related with stages of relative lowering of the sea level.

    The purpose of this paper is to document the changes observed in the Quaternary dinoflagellate assemblages from 80 core samples from the Campos Basin. The Interglacial (Subzone X1), Glacial (Subzones Y5 to Y2), Last Glacial Maximum (Subzone Y1) and Post-Glacial (Zone Z) intervals were identified. High abundance of Operculodinium centrocarpum suggests the warm, high salinity and nutrient-poor water conditions dominated the upper water column of the Campos Basin. The climate and oceanic current dynamic of the continental slope of the Campos Basin appears to has been a significant controlling factor in the distribution of dinocysts, particularly of O. centrocarpum, during the Pleistocene/Holocene transition.

    Campos and Espirito Santo basins display several similar geochemical aspects. The microbial and other degradation processes caused changes in the composition of the oils in the reservoir rocks. The oils are biodegraded in different degrees, with the reservoir temperature developing an important role in the control of the biodegradation process. The migration pathway model is similar for Campos and Espirito Santo basins, involving the upward secondary migration through a window in the evaporitic seals. The oils passed to the marine sequence where migration and accumulation were controlled by faults, regional unconformities and by reservoirs. The geochemical correlation of oils are realized by gaseous and liquid chromatography analysis, carbon isotopes and biolabelled compounds. (author)

    In the northern area of Campos Basin salt gliding/spreading processes promoted the break-up and transport of Cretaceous and Tertiary rocks overlying the evaporites. This process is known as raft tectonics, and it represents the most extreme form of thin-skinned extension above the salt decollement surface. Three distinct geotectonic domains were recognized that formed in response to the raft tectonics. The first one, confined to the shallower shelf portion of the basin, is characterized by minor extension (pre-raft domain), probably because of small salt thickness and low gradient. In the second domain (or disorganized rafts domain), located in distal platformal and slope areas, seismic sections show the occurrence of blocks or rafts with angular shapes, sometimes imbricated and frequently discontinuous. In the third domain, or domain of organized rafts, located in bacinal region, seismic sections show a more continuous raft pattern, often folded because of salt compression in the distal portions of the basin. The main purposes of this work is to characterize these three tectonic domains distinguished by raft tectonics, as well as their importance in hydrocarbon accumulations in calcarenites. (author)

    The Environmental Monitoring Project (PMA) aims to report environmental changes arising from drilling activity, in relation to the marine fauna. This project can also help in the monitoring of accidental spills. Since the professionals spend six hours of the day monitoring the ocean around the rigs, they can locate and identify oil stains, notify the responsible onboard, and also help in the monitoring of the oil stain. Such Project has been developed onboard a drilling unit working in Campos Basin. The results presented here were collected during the drilling activity in Bijupira and Salema fields, by Shell Brasil Petroleo Ltda, from July 13th to October 8th, 2011.

    The evolution of the Atlantic Brazilian basins is a target of researches since the firth discovery of oil deposits. With the advance of the geophysical methods the understanding of the structures in depth became possible. The objective of this paper is to determine if the adjacent basement in the north of Campos Basin has significant influence in the identification of areas that can contain hydrocarbons. Therefore, lineaments had been extracted with SRTM images of continental basement and the main alignment was correlated with gravimetric anomalies map and seismic data. Eight levels on seismic data had been interpreted (basement, top rift, shallow water Albian, Albian, mid-Oligocene and mid-Miocene). In all levels were identified a fault normal system, which cut sediments since basement until the Recent. The main direction of the basement is NE-SW, and the alignments formed for basin basement faults coincide with this direction, what indicates that the system is active and also genetically related.

    Full Text Available Our research focused on a specific group of workers – those employed in the petroleum industry in the Campos Basin (RJ by Petrobrás – and service providers. Their interviews provide empirical material for a possible new approach to the offshore workers’ environment based on some issues raised by Axel Honneth, current Critical Theory’s exponent, such as the experience of disrespect, moral feelings of indignation, and his articulation in search for solutions to configure or not a struggle for recognition. We attest the analytical potential of the Honnethian premises in guiding empirical investigations which may lead to the review of the production relationship as a space to experience the claim for its humanization within advanced capitalism, in which the tendency to individualistic and conformist solutions prevail as they are triggered by the concurrent work precariousness.

    Full Text Available In the drilling and production of oil at sea, a large quantity of potable water used is most commonly transported to oil platforms using offshore supply vessels (OSVs. Sea water desalination is used as well, but only in a few oil platforms. To minimize energy consumption, water supply options were studied. The desalination of seawater and the reusing of streams of grey water and black water were evaluated and compared with the characteristics of the current supply via OSVs. In both desalination and OSV water supply options an electrolytic wastewater treatment plant is used. The objective of this study was to analyze the current situation regarding water supply on offshore platforms located in the Campos Basin, Rio de Janeiro, Brazil, and to propose measures to take advantage of opportunities to reuse water and reduce energy expenditure. Two alternative scenarios were developed that involved the reuse of water that comes from the effluent of a biological wastewater treatment plant (WWTP. Information on the logistics of supplying water to platforms was obtained through direct consultation with companies and sources in the literature. The results show that annual energy consumption (uptake, treatment, transportation, use and waste water treatment of water on offshore platforms is currently 1.89 GWh, and that a reduction of 1.8 GWh of the energy consumed can be achieved using advanced reuse treatments. Energy consumption in the water reuse treatment is more competitive than those of transport by OSVs or seawater desalination.

    The present conquest of the self-sufficiency is a result of 3 decades of investments that started with the discovery of the well 1-RJS-9A in 1974. The second leap was the discovery of giant fields in the 1980 including Marlim (1984) and Albacora (1985) among others. This first two conquests were basically technical and were recognized by the OTC in 1991 and 2000. The third leap was the utilization of project finance structures. We examine the role of project finance in the main projects developed by the PETROBRAS E and P - Exploration and Production - segment in the Campos Basin region. These projects allowed PB to invest more than US$ 6 billion dollars in a five year interval increasing production in 12 oil fields by 75% in a 7 years interval which later enabled PB to be self-sufficient in oil production. The financial structures of Albacora, Barracuda, EVM and Marlim are shown and discussed in various aspects which including structure, schedule, conditionalities, warranties, management of the SPEs and relationship with international agencies. Considering the present quest of developing Tupi and Jupiter which might represent investments around US$ 80 billion and it's impacts to the PETROBRAS capital structure and risk this might be a useful discussion.

    The offshore oil industry is characterized by complex systems in relation to technology and organization of work. Working conditions are hazardous, resulting in accidents and even occasional full-scale catastrophes. This article is the result of a study on work-related accidents in the offshore platforms in the Campos Basin, Rio de Janeiro State. The primary objective was to provide technical back-up for both workers' representative organizations and public authorities. As a methodology, we attempt to go beyond the immediate causes of accidents and emphasize underlying causes related to organizational and managerial aspects. The sources were used in such a way as to permit classification in relation to the type of incident, technological system, operation, and immediate and underlying causes. The results show the aggravation of safety conditions and the immediate need for public authorities and the offshore oil industry in Brazil to change the methods used to investigate accidents in order to identify the main causes in the organizational and managerial structure of companies.

    This article focus on an innovative project launched by PETROBRAS with the main purpose of minimizing the impacts of drilling activities in Campos Basin, over the fishery industry in the northeast region of Rio de Janeiro. This project is seen as a relevant part of PETROBRAS' corporate social responsibility actions. In this sense, it is supposed to consider the interests of all parts directly and indirectly related and affected by the companies' intervention. The major conclusion is that the project could be an important first step to restructure the fishery sector an to harmonize the 'sea users'. A potential improvement could be the promotion of a more effective participation of fishermen in the project and the inclusion of the social and environmental dimensions. (author)

    Martins, Luiz M. R.

    The Campos Basin is the best known and most productive of the Brazilian coastal basins. Turbidites are, by far, the main oil-bearing reservoirs. Using a four component (4-C) ocean-bottom-cable (OBC) seismic survey I set out to improve the reservoir characterization in a deep-water turbidite field in the Campos Basin. In order to achieve my goal, pre-stack angle gathers were derived and PP and PS inversion were performed. The inversion was used as an input to predict the petrophysical properties of the reservoir. Converting seismic reflection amplitudes into impedance profiles not only maximizes vertical resolution but also minimizes tuning effects. Mapping the porosity is extremely important in the development of a hydrocarbon reservoirs. Combining seismic attributes derived from the P-P data and porosity logs I use linear multi-regression and neural network geostatistical tools to predict porosity between the seismic attributes and porosity logs at the well locations. After predicting porosity in well locations, those relationships were applied to the seismic attributes to generate a 3-D porosity volume. The predicted porosity volume highlighted the best reservoir facies in the reservoir. The integration of elastic impedance, shear impedance and porosity improved the reservoir characterization.

    The constant demand for Services Companies in Oil and Gas Industry to reduce the environmental impacts has led to a race in search of new cleaner technologies. Fluids with low toxicity are the target of research and development by the companies which are committed to ensure the aspects of quality, health, safety and environment from manufacturing up to the use in the final destination of these products. The replacement of these fluids is happening at a larger speed than in the past on the based in two factors: greater awareness on the part of these companies in relation to the environmental and by new environmental laws. The fluids systems used in fracturing operations are not an exception to this rule. Service companies today are in the process of replacing their formulations with systems less aggressive to the environment so-called 'green' systems. In this context the new technological developments of fracturing fluids are of fundamental importance to assist the new environmental requirements of both operators and government regulatory bodies and also to ensure better effectiveness of these products. This paper reports the research, development and application of new environmentally acceptable fracturing fluids technology, reviews the pioneering case histories in offshore operations and the benefits experienced in the Campos Basin - Brazil.

    Mercury (Hg) is a global pollutant due to its ability to undergo long-range transport from source regions to remote parts of the world, and its ubiquitous presence in aquatic ecosystems. The Hg isotope ratios could be an effective tool for tracing the sources and process of Hg in the environment. This study aimed to establish the distribution of mercury in surface sediments of three transects (25- 3000m water depth) in continental shelf and slope in Campos Basin-RJ-Brazil, using the Hg isotopes to understand the geochemical processes relating to Hg cycling that occur in a subtropical coastal environment. The study area was divided into three transects: A (located to the south and close to a upwelling area), D (located opposite the mouth of the Paraiba do Sul River) and I (located north near the top of Vitória-ES). Sampling isobaths were 25, 50, 75, 100, 150, 400, 700, 1000, 1300, 1900, 2500 and 3000m. The Total Hg, MMHg and Hg stable isotopes were determined based on EPA Method 1631, EPA method 1630 and Foucher and Hintelmann (2006), respectively. The silt/clay ranged from 0.05 to 95%, and the organic carbon (OC) from 0.07 to 1.43 % for all transects. THg and MMHg concentrations in the shelf were 11.9 ± 7.2 (1.7- 22.2) ng.g-1 and 0.15 ± 0.12 (0.02 - 0.40) ng.g-1; in the slope 30.3 ± 9.2 (11.6 - 51.6) ng.g-1 and 0.13 ± 0.06 (0.03 -0.29) ng.g-1 , respectively. The δ202Hg and Δ199Hg varied from -0.32 to -1.85 ‰ (-0.79 ± 0.44‰) and -0.41 to 0.09 ‰ (-0.03 ± 0.12 ‰) for all transects, respectively. The delta values between both regions are significantly different, the shelf region showed δ202Hg from -0.59 to -2.19 ‰ (mean: -1.52 ±0.65) and Δ199Hg from - 0.53 to 0.08 ‰ (mean: -0.27 ±0.55) and the slope region were observed δ202Hg values from -0.32 to -1.82 ‰ (mean: -0.73 ±0.39 ‰ n=18) and gΔ199Hg from -0.23 to 0.09‰ (mean: -0.02 ±0.08‰ n=5). The slope appears to be enriched with heavier isotopes compared to the shelf, however, in the

    PETROBRAS E and P department (up-stream segment) had assigned first contract for pipeline inspection using smart pigs in 1995. Up to this time only TRANSPETRO (down-stream segment) had an experience with those inspections mainly focused on first generation tools. On this contract, it was first time required high resolution tools, which had bigger defect detection capability and sizing accuracy as advantages but with higher cost. It was regarded necessary due to high costs involved on a virtual sub sea survey or repair. The investment was regarded fair as there is no way to establish correlation digs as well as normally done after on shore pipelines surveys. Actually the first internal inspection was carried out in 1997. From this period it has been realized the enormous importance on verifying all platforms installations and all procedures involving cleaning runs. We have taken many lessons from these inspections. Commissioning using all kinds of cleaning pigs (some was invented) that could be specially contracted on scaling removing jobs; diesel batch to make easy US pigs inspection, cleaning steps that should be gradual to allow receiving of debris without disturbing platforms process efficiency; special tools designed in-house to meet some specific installations requirements as limited pigability; were some issues that demanded efforts on this period. PETROBRAS/E and P through its Campos Basin Production Unit has been strongly involved on looking for solutions to keep its sub sea pipeline net integrity; a strategic asset that will guarantee the Brazilian development on oil and gas production.

    According to the Brazilian legislation, the Environmental Impacts Monitoring Plan is one of the requirements of the environmental licensing to offshore oil and gas production activities. The Monitoring Plan's structure is based upon sampling and evaluation of numerous parameter settings in water and sediment compartments, while the conclusion as to the existence or absence of impact is obtained after statistical analysis of the results. The aim of this work was to evaluate the methodological adequacy of monitoring and to calculate the statistical power of tests applied with the purpose to determine the reliability of their findings. Experiences in other countries like Australia have shown that this is an important instrument in preparing an effective environmental study regarding the detection of impacts. In Brazil, this is the first initiative to critically evaluate the results of reports of environmental monitoring originated from the licensing of hydrocarbons production activities. Campaign reports forwarded to the environmental agency in charge, i.e., the Brazilian Institute of Environment and Renewable Natural Resources (IBAMA), and the selected ventures are located in the Campos Basin and have different operating companies. The results were both relevant and concerning. All monitoring reports confirmed the absence of alterations or impacts on the biotic media for sediment compartments, but the greater statistical power did not exceed 25% for a great magnitude impact. Thus it was concluded that if the oil production activity has caused alterations or impacts to bentonic organisms, the carried out monitoring was inefficient to detect them even if they were of great magnitude. This analysis is expected to be an instrument for future changes in environmental licensing procedures e for the improvement of the environmental public management in Brazil. (author)

    Recent discoveries in the Espirito Santo Basin confirm the importance of it in the national exploratory scenery (oil and gas production). The new fields like Carapo and Camarupim, beyond others, next to already known Golfinho and Canapu, totalize an addition of 560 million barrels. In this way, studies in the area add importance, as the case of the present research, where if it looked to analyze the influence of Colatina Belt in Espirito Santo Basin and secondarily in Campos Basin. The results had been gotten through the integration of diverse data, such as lineaments extracted from images SRTM, potential maps and analyze of seismic lines. It was concluded that the Colatina Belt if projects for the interior of the basins, but that the same one seems to be dislocated in relation to the direct projection of the continental features, being that its influence can be felt with bigger emphasis in the Campos Basin, while in the Espirito Santo it look like to have low importance with regard to the exploration aspects. Also it was verified the presence of numerous halo kinetic structures that affect all the mapped horizons, this element determine great importance in the generation of structural traps. (author)

    The Kribi-Campo sub-basin is composed of an Early to Mid Cretaceous series from West Africa's Atlantic coast and is located in southern Cameroon in the Central African equatorial rain forest. It is the smallest coastal basin in Cameroon and forms the southern part of the Douala/Kribi-Campo basin known as Douala basin ( s.l.). Until now, no detailed sedimentological studies have been carried out on the outcrops of this basin located in the Campo area. The aim of this study was to characterise the depositional environments, vertical evolution and tectonic context of these Lower Cretaceous series in order to make a comparison with adjacent basins and replace them in the geodynamic context. Facies analysis of the Lower Mundeck Formation (Lower Cretaceous) indicates the presence of four major, interfigered facies associations, that are inferred to represent elements of an alluvial to lacustrine-fan delta system. The clast lithologies suggest proximity of relief supplying coarse-grained sediment during the deposition of the Lower Mundeck Formation at Campo. The general dip and direction of the bedding is approximately 10°-12°NW, which also corresponds to the orientation of the foliations in the underlying metamorphic basement. The main sedimentary succession is characterised by a major retrogradational/progradational cycle of Late Aptian age, evaluated at about 3 Ma, with a well-developed progradational trend characterised by fluctuations of the recognised depositional environments. Fluctuations in lake level and sediment supply were possibly controlled by active faults at the basin margin, although climatic changes may have also played a role. The consistently W-WNW palaeoflow of sediments suggests that the palaeorelief was located to the east and could be oriented in a NNE-SSW direction, downthrown to the west. Local outcrops dated as Albian, both north and south of the main outcrop, display some marine influence. These deposits are cut by 040-060 faults parallel to

    The knowledge of the mechanical properties of the rocks is essential in the calculation of the stability of the oil wells and in the elaboration of drilling projects, because they help in the selection of the best equipment for each geologic scene. In these activities, the most important mechanical property is the rock compressibility, which can be calculated from the sonic geophysical log, but this one, not always available in the well data set. In order to minimize this limitation, it was developed, in this work, a methodology to simulate it through an algorithm that utilizes fuzzy logic concepts, using as input data gamma ray and resistivity logs. The basic principle of this methodology is to propose that any geophysical log, including the sonic log, can be considered function of other measured geophysical logs in the same depths. On the other hand, to test the confidence of this approach, it was compared with two others commonly used in the simulation of logs: the linear multiple regression and the neural network back-propagation, showing, our methodology, however, better results. Finally, to validate the method, it was tested using wells from Namorado Oil Field in Campos Basin, which contains gamma ray, sonic and resistivity logs. (author)

    Full Text Available Here, we describe pollen grains extracted from a Pleistocene-Holocene sediment core (BU-91-GL-05; 22°48'45"S; 41°54'13"W taken from the Albacora Slope (22°48'45"S; 41°54'13"W, located in the Campos Basin of the northern region of the state of Rio de Janeiro, Brazil. The analysis resulted in the identification and morphological description of 46 types of pollen: one of a gymnosperm genus (Podocarpus; and 45 of angiosperm taxa across 27 families-one family of monocotyledons (Poaceae and 26 families (30 types of dicotyledons. The most common angiosperm families were Amaranthaceae (Chenopodium, Amaranthus and Gomphrena; Fabaceae (Fabaceae type, Bauhinia, Inga and Canavalia; Malpighiaceae (Tetrapteris, Heteropteris and Peixotoa; Malvaceae (Sida, Abutilon, Hibiscus and Pseudobombax; Rubiaceae (Faramea, Borreria and Psychotria; Asteraceae (Eupatorium and tribe Vernonieae; Bignoniaceae (Bignoniaceae type, Adenocalymma and Tabebuia; and Onagraceae (Fuchsia and Ludwigia. The palynoflora in this study are associated with dense montane and submontane Atlantic Forest, semideciduous forest and restinga (coastal woodland, all of which are present in the state of Rio de Janeiro. Palynological analysis can provide important data about paleovegetation and paleoclimatic changes in the studied area during the Quaternary, specifically in the last 145,000 years.

    Carbon and oxygen isotope data of limestones from Campos, Santos and Espirito Santo basins provided additional information on the sedimentation environments of these carbonates. The predominance of δ 13 C values between + 1,0 per mille and - 1,0 per mille samples from the Tertiary and the middle section of the Jiquia Stage (Lower Cretaceous) could indiccate, for both carbonate sequences, deposition in a normal marine environment. However, the absence of marine fossils in the Jiquia Stage but not in the Tertiary allows to suggest a normal marine environment for the latter and saline lakes for the former. More positive δ 13 C values in the upper portion of the Jiquia Stage and in the Alagoas Stage suggest a restricted marine environment, with a tendency to hypersalinity. During the Albian the carbonate sedimentation could have occurred in a marine enrironment with an above normal salinity, as indicated by values of δ 13 C between + 3,0 per mille and + 4,0 per mille. According to δ 18 O data, the surface waters were warm, with a tendency of becoming gradually cooler towards the top of the Tertiary. (Author) [pt

    With a proven capacity to identify oil slicks in offshore regions, RADARSAT-1 imagery can be useful for oil exploration purposes. The paper discusses the seepage detection method at Campos Basin, offshore Rio de Janeiro State, which is responsible for 80% of the Brazilian production of oil and gas. It is known that the horizontal migration of petroleum can occurs over tens or even hundreds of kilometers, where the source rock placed in more deep locations can be linked with shallow reservoirs or traps and even reach the ocean. It means that seepage can provide information for risking petroleum charge at basin scales, and cannot have a direct relation with the geographical position of the interpreted seeps and possible filled prospects. A good understanding of the geology, and hence the petroleum systems of a basin is the key to use seepage in exploration. The work is divided into three main steps. First step were select oil seepages interpreted at Campos Basin where is found several giant petroleum fields. Second, the geology of the study area and its structural and stratigraphic features were analyzed, in order to identify possible migration pathways related to faults generated by halokinesis. Another important aspect is the presence of 'windows' or ducts in the evaporates beds allowing the contact between the section that contains source rocks and the turbidities reservoirs, that contain the majority of the oil discovers. All these features were interpreted based on a regional dip seismic line (203 - 76), and a geologic cross section with E-W orientation, showing the structure of the Marlim Field. Finally, all the information was integrated in a Geographical Information System (GIS), and then analyzed in an interdisciplinary environment, with the intention to link possible routes of oil migration to post-evaporites reservoirs or to interpreted seeps.

    The objective of this research is to present the results of the marine biota visual monitoring developed during the seismic survey in the north area of Campos Basin. The monitoring lasted five months, between 14 February and 14 July 2007, reaching, on average, eleven hours and fifty one minutes of sign effort per day. It was conducted by fourteen marine biota catch sign, three for each period of boarding, that took over during all period of the activity. Sixty two cetaceans were registered, eight belonging to suborder Odontoceti and four belonging to suborder Mysticeti. Tursiops truncatus was the predominant species in number of registers, followed by Megaptera novaeangliae. It's important to report that during all seismic activity period there wasn't any cetacean register presenting any behavior disturbance. (author)

    This work will approach the current level of development of the installation of connected underwater equipment to flexible lines in the underwater engineering operations in Campos' Basin. The project will show studies, analysis and simulations (through software developed by PETROBRAS) about the installation of the largest equipment laid in the 'in-line' system (connected to flexible lines) in Brazil - and one of the largest of the world: the ESDV (Emergency Shut Down Valve) of the gas pipeline P-40 x FPSO-MLS, in the South Marlim field, in Campos' Basin. This ESDV, of about 18.000 kg, 4 m height and 6,5 m length, has the purpose of assuring the safety conditions on the facilities, interrupting the gas flow exported for P-40 in case of emergency situations. Its installation opened a new alternative in releasing underwater equipment, using the ships that install the flexible lines. This operation occurred in June, 2004, and required the use of a second vessel for support and monitoring of the ESDV laying. The ESDV was installed at 400 m from FPSO-MLS, in a water depth of 1.137 m. This method shall be used broadly by the company in the implantation of the new units of Campos' Basin, and the upcoming studies must consider the gradual increase of the water depth in the new projects. This work will focus the technological development in this area, and one of its purposes is to foresee the future difficulties that can appear in the implantation of the production systems in deep and ultra-deep waters.

    Based essentially on geochemical data, this work aims at defining constrain to the petrogenesis of the Eocretacious basalts from the Campos and Pelotas marginal rift basins (South-Southeast Brazil). Geochemical modeling, including quantification of mantle sources and binary mixing methods, were performed in order to contribute to the elaboration of geo dynamic models related to the initial stages of Gondwana breakup. Basalts from Campos and Pelotas basins comprise two transitional series with tholeiitic affinities. All basalts from the Campos Basin can be assigned to a low-TiO2 suite (TiO2 1.20 +- 0.12 wt %; Ti/Y = 272); whereas basalts from the Pelotas Basin comprise a low-(TiO2 = 1.19 +- 0.02 wt %; Ti/Y = 288) and a high-TiO2 suites (TiO2 = 2.10 +- 0.19 wt %; Ti/Y = 387). Non-modal batch partial melting modeling showed that the La/YbN = 5.78 generation ratio of the Campos Basin suite was obtained from 21% of partial melting of lherzolite garnet. The same model required a source with smaller amounts of garnet (melted at 28%) to generate the La/YbN generation ratio of the low-TiO2 suite of the Pelotas Basin. Larger amounts of grenade and less partial melting (22%) were necessary to generate the La/YbN ratio of the high-TiO2 suite of the Pelotas Basin. The simple binary model shows that parent compositions of Campos and Pelotas cannot result from the mixture of T C (Tristao da Cunha) and SCLM (Sub continental Lithospheric Mantle). The best results obtained suggest the participation of component N-Morb in the generation of basalt suites of the Campos and Pelotas basins (respectively 61% and 93% of partial melting). Tristao da Cunha seems to have been an important component to the generation of the basalt suite of the Campos Basin (at 39% of partial melting). In Pelotas, the model indicates restricted contribution of SCLM reservoirs. (author)

    This study integrates palynofacies analyses and the sedimentological and stratigraphic model of the Oligo-Miocene/Miocene siliciclastic deposits from the stratigraphic interval of the shallow continental platform up to the slope/basin of the Oligo-Miocene/ Miocene of the Campos Basin proposed. The main objective of the palynofacies study was to characterize the particulate sedimentary organic matter to obtain information about the proximal-distal relationship and the sedimentary organic matter preservation and depositional environmental conditions. The 158 core samples collected in 29 wells of the 9 oil production fields (Albacora, Barracuda, Marlim Sul, Marlim, Voador, Marlim Leste, Moreia and Albacora Leste), were studied. This technique provides information about the proximal-distal relationship and the paleoenvironmental conditions of deposition and preservation of sedimentary organic matter, to facilitate the evaluation and comparisons between the associations of particulate organic components. Thus, the palynofacies technique can be used as another tool in the characterization of depositional systems, based on the spatial and temporal distribution of sedimentary intervals. In general the palynofacies assemblages showed the predominance of the Phytoclast Group (terrestrial derived organic matter) at various degradation stages due to the selective preservation process diagnosed in the studied samples. Some samples, revealed high dinocysts percentages indicative of transgressive depositional conditions. From the obtained data, it was possible to characterize the stratigraphic sequences according to the distribution of particulate organic content (e.g. influence of fluvio-deltaic systems, oxygen system, regressive-transgressive tendencies of each sequence). Additional analyses of Total Organic Carbon (% wt) showed the control of the particulate components from the Phytoclast Group on the TOC (% wt) content, suggesting that the relative sea-level variation curves

    The main goal of this paper is to show the importance of a secure and efficient information system for a company, from the plant floor to the top management level, as well as the impact of this efficiency on the employees' working routine and on the company's results. The change in the working methodology of the company brought by the implementation of the Operational Information System allowed the sharing of all the information that used to be concentrated almost exclusively at the operational level in true information islands (the offshore platforms) and the delivery of information in real-time to all engineers and technicians from various onshore areas of the company: process monitoring, maintenance, technical assistance, laboratory and planning, also making possible the integration with the Enterprise Management System. All these features allowed an increase in the knowledge about the process, leading to time saving and improvement of the cost/return of investment relationship in several kinds of projects and processes. After the system had been implemented it was possible to monitor in real-time and store all the process data of approximately 30 offshore petroleum exploration platforms of the Campos Basin in a unique repository.

    The PPG-1/PGP-1 crude pipeline links Pargo and Garoupa platforms at the Campos Basin. Garoupa process the crude removing water and transferring it to the coast. During 10 years this pipeline had operated with more than 20% of water. In 2001, the pipeline was surveyed with a MFL pig. The results showed internal corrosion in almost the entire 22 inches pipeline concentrated on its bottom part (channeling corrosion). This type of indication has a high difficult on sizing using MFL tools. The logistic to replace the damaged pipeline was started but before that, the pipeline was surveyed with a US pig to improve the sizing of all defects. The results of the US pig confirmed the MFL report and were decided to keep all tasks in order to replace the corroded segment. At that time, a new inspection pig was under development on PETROBRAS Research Center in cooperation with PUC-Rio/CETUC. It was decided run this tool in that pipeline to compare its results against the two most common methods used for pipelines inspections. (author)

    Full Text Available This paper presents morphological descriptions and ecological data of cryptogam spores and other non-pollen palynomorphs from Quaternary sediments of Campos Basin, Rio de Janeiro, SE Brazil. The ages were derived from biostratigraphy of planktonic foraminifers and two radiocarbon dates, and suggest that sediment deposition started in the last 140,000 years BP. Thirty different types of palynomorphs were identified, described, and photographed: two bryophyte spores (sensu lato; 21 pteridophyte spores; four freshwater microalgae; onePseudoschizaea; and two microfungi. Some of the identified spores (Sphagnum, Blechnum, Cyatheaceae, Dennstaedtiaceae, Lycopodiella, Microgramma, Polypodium, Acrostichum, Pityrogramma, and Lygodium are related to the modern flora found on the northern coast of Rio de Janeiro State, at the Restinga of Jurubatiba, from vegetation types such as shrub swamp/coastal swamp formation, seasonally flooded forest, Clusia and Ericaceae woods, and disturbed vegetation. The freshwater microalgae and the microfungi are also presently recorded from the coastal lagoons of this region. The high spore concentration in slope sediments reflects the intense terrigenous influx, caused by a relative low sealevel during glacial stages. Palynological analysis suggests the presence of taxa from flooded forests and humid areas in the coastal plain during glacial and interglacial stages of the Late Pleistocene.

    There are 22 species of Hamacantha registered from all over the world, and frequently from deep-waters, only two of which had previously been reported from the SW Atlantic. Here we describe a third species for this area, Hamacantha (H.) boomerang sp. nov., collected from deep-sea coral mounds at Campos Basin (off Rio de Janeiro state). We found oxeas 271-630 µm long, diancistras in three size classes, 125-155, 45-69 and 20-29 µm, and toxas, 58-82 µm. This is the only Hamacantha combining oxeas and toxas, but the latter are very rare. The species approaches the Caribbean H. (H.) schmidtii (Carter, 1882), where we observed oxeas 390-495 µm long, and diancistras in three size classes, 109-124,  44-54 and 26-41 μm, however toxas appear to be absent. Both species are clearly distinct by micrometric values, as well as the overall morphology of the smaller diancistras, distinct from the intermediate category in the new species, but quite similar in H. (H.) schmidtii. Hamacantha (Vomerula) falcula approaches the new species very closely in microsclere dimensions and morphology, but is set apart by its styloid and smaller megascleres.

    Living (stained) benthic foraminifera from deep-sea stations in the Campos Basin, southeastern Brazilian continental margin, were investigated to understand their distribution patterns and ecology, as well as the oceanographic processes that control foraminiferal distribution. Sediments were collected from 1050 m to 1950 m of water depth during the austral winter of 2003, below the Intermediate Western Boundary Current (IWBC) and the Deep Water Boundary Current (DWBC). Based on statistical analysis, vertical flux of particulate organic matter and the grain size of sediment seem to be the main factors controlling the spatial distribution of benthic foraminifera. The middle slope (1050 m deep) is characterized by relatively high foraminiferal density and a predominance of phytodetritus-feeding foraminifera such as Epistominella exigua and Globocassidulina subglobosa. The occurrence of these species seems to reflect the Brazil Current System (BCS). The above-mentioned currents are associated with the relatively high vertical flux of particulate organic matter and the prevalence of sandy sediments, respectively. The lower slope (between 1350 and 1950 m of water depth) is marked by low foraminiferal density and assemblages composed of Bolivina spp. and Brizalina spp., with low particulate organic matter flux values, muddy sediments, and more refractory organic matter. The distribution of this group seems to be related to episodic fluxes of food particles to the seafloor, which are influenced by the BCS at the surface and are deposited under low deep current activity (DWBC).

    This work intended to study general aspects related to natural radioactivity, focusing on its occurrence in the oil industry and on sludge and scales samples taken from the Oil E and P region from Campos's Basin. The physical and chemical analysis and the statistical treatment were carried out with the objective of determine the samples composition checking the differences between the sludges and the scales. Third six representative samples were obtained from the Radioprotection and Dosimetry Institute (IRD/CNEN), Brazil, taking into account factors such as activity concentration, physical and chemical aspects and origin. After the oil extraction, samples were classified by aspects as color and granulometry. Ali the studied samples were analyzed by X-rays diffraction being identified the presence of barite, calcite, quartz among others. The results supplied a base for the elaboration of a successive determination scheme which comprehended residual organic material, carbonate, sulfate, silica, chloride and metals as the alkaline, earthy alkaline, aluminum, etc. The sludges presented a highly variable chemical composition, being rich in silica and carbonates. The main components analysis showed a statistical valid relationship among the radium isotopes and the carbonates presence. On the other hand, the scales are made of barium and strontium sulfates (75%), presenting a minor variation on its chemical composition and in the existing radium content. Due to this low variability of the barium, sulfate and radium contents, it has not been possible to consider valid a relationship that could exist among them in the application of the main component analysis.

    This paper assesses the effects of non-aqueous fluids (NAF)-associated drill cuttings discharge on shelf break macrobenthic communities in the Campos Basin, off the southeast Brazilian coast, Rio de Janeiro State. Samples were taken with a 0.25-m2 box corer from surrounding two oil and gas wells on three monitoring cruises: before drilling, three months after drilling, and 22 months after drilling. Statistical methodologies used Bayesian geostatistical and analysis of variance models to evaluate the effects of the NAF-associated drill cuttings discharge and to define the impact area. The results indicated that marked variations were not observed in the number of families between cruises, though there were changes in the fauna composition. The changes seen in biological descriptors in both control and background situation areas were not considered significant, showing a temporal homogeneity in means. The impact area presented changes in biological descriptors of communities and trophic structure during the three cruises and such changes were correlated to chemical and physical variables related to the drilling activities, as a result of the mix of drill cuttings and sediment and the anoxic conditions established in the substrate. In that area, three months after drilling, a decrease in diversity and an increase in density, motile deposit-feeders and Pol/Crp ratio, and dominance of opportunistic organisms, such as the capitellid Capitella sp., were observed and, 22 months after drilling, an increase of diversity, reduction of dominance of capitellid polychaete, changes in the fauna composition, and a dominance of opportunistic burrowing and tube-building organisms were observed, indicating an ecological succession process.

    Mercury (Hg) may originate from both anthropogenic and natural sources. The measurement of spatial and temporal variations of Hg isotope ratios in sediments may enable source identification and tracking of environmental processes. In this study we establish the distribution of mercury concentrations and mercury isotope ratios in surface sediments of three transects along the continental shelf and slope in Campos Basin-RJ-Brazil. The shelf showed on average lower total Hg concentrations (9.2 ± 5.3 ng g -1 ) than the slope (24.6 ± 8.8 ng g -1 ). MMHg average concentrations of shelf 0.15 ± 0.12 ng g -1 and slope 0.13 ± 0.06 ng g -1 were not significantly different. Distinct differences in Hg isotope ratio signatures were observed, suggesting that the two regions were impacted by different sources of Hg. The shelf showed more negative δ 202 Hg and Δ 199 Hg values ranging from -0.59 to -2.19‰ and from -0.76 to 0.08‰, respectively. In contrast, the slope exhibited δ 202 Hg values from -0.29 to -1.82‰ and Δ 199 Hg values from -0.23 to 0.09‰. Mercury found on the shelf, especially along the "D" and "I" transects, is depleted in heavy isotopes resulting in more negative δ 202 Hg compared to the slope. Isotope ratios observed in the "D" and "I" shelf region are similar to Hg ratios commonly associated with plants and vegetation and very comparable to those detected in the estuary and adjoining mangrove forest, which suggests that Hg exported from rivers may be the dominating source of Hg in near coastal regions along the northern part of the shelf.

    The deep-water marine sedimentary environment of the Cenozoic of the Campos Basin is examined at the modern sea floor, where it can be better understood. This environment is responsible for the genesis of the turbidite systems of the Carapebus Formation, the reservoirs that hold more than 90% of Brazil's petroleum reserves. The study was developed with the records of regional side-scan sonar, swath bathymetry, sub-bottom profiler data, standard multichannel 3D seismic surveys and piston cores covering almost the entire basin. After leaving the Almirante Camara Canyon, the turbiditic flows erode the muddy debris apron surrounding the continental slope and begin to deposit thick layers of clean sand into a big trough in water depths of 1800 m to 3000 m. The trough is 3.5 km wide, 150 m deep, 150 km long, and is formed by a chain of salt withdrawal mini-basins. In some places the sea floor is flat enough to develop today a depositional lobe, in all aspects analogous to the best, geologically ancient petroleum reservoirs in the basin. Aspects of the system: 1) the arcosean sands are brought by the river, cross the shelf, the incised valley, the canyon, and deposit as turbidites - they do not originate from a collapse of the continental slope; 2) a wide muddy debris apron surrounds the continental slope (slope apron), and represents a huge volume of sediment in the Campos Basin ; 3) the turbidites do not develop a submarine fan, but are deposited in an elongated trough formed by salt tectonics; 4) the turbidite beds, both in the lobe or in the trough, are not deposited during a single episode, but in multiple events over significant geologic time in which small channels which brought the turbidites avulse and meander along the entire depositional area, building a single amalgamated bed; 5) classic channel-levees are not present because this system comprises a sandy braid plain and the levees are as sandy as the channel; 6) a hierarchical depositional model for bulb

    Full Text Available Emission factors of natural processes and anthropogenic activities were used to estimate nutrients and metal loads for the lower Macaé river basin, which hosts the operational base for the offshore oil and gas exploration in the Campos Basin. The estimates indicated that emissions from anthropogenic activities are higher than natural emissions. Major contributing drivers include husbandry and urbanization, whose effluents receive no treatment. The increasing offshore oil exploration along the Brazilian littoral has resulted in rapid urbanization and, therefore might increase the inshore emission of anthropogenic chemicals in cases where effective residue control measures are not implemented in fluvial basins of the region.

    Sediment samples were taken from a total of 133 stations in two sampling campaigns (winter 2008/2009 and summer 2009) distributed on the shelf and in transects which extended from 25 m to 3000 m water depth. The region under study is influenced by upwelling, river discharge and beyond the platform by five different water masses. The goal of the work was to examine by means of carbon isotopic composition and lipid biomarkers the provenance of the organic matter pool in the sediments so as to evaluate source strength, degradation and relevance to sustain a benthic community. Isotopic and molecular indicators show the influence of the outflow of the Paraiba do Sul river on the quality and quantity of organic matter (OM) that accumulates on the shelf; however, this influence is dependent on the hydrological regime on the river's basin. In the upwelling region of Cabo Frio, the OM is mainly of autochthonous sources, and evidence of export of labile OM produced on the shelf to the slope was found, which can potentially influence the benthic process at depths between 700 and 1000 m.

    Qualitative analysis in calcareous nanno fossils is a powerful tool for bio stratigraphic uses, principally in identification of bio zones and determination of relative age. But quantitative studies must be applied for pale oceanographic applications and high resolution bio stratigraphy. In order to better understand the relationships between the different species of nanno fossils, new methodologies and non-traditional correlation tools were tested on a 18 m upper Campanian - lower Maastrichtian core from Campos Basin. Multiple regression helped to determine the best counting method. Watznaueria barnesae and Micula decussata dominate the fossil assemblage and have inverse abundances to each other. Both were opportunist species in competition for nutrients. Q mode factorial analysis (57 samples, 19 variables) was applied to the same core and shows that two factors explain 99.2% of the total variance of the micro fossil assemblage. The first factor represents 83.6% and the second factor only 15.6% of the total variance. The former is associated with Watznaueria barnesae, Cribrosphaerella ehrenbergii and Stradneria crenulata, which represent the original population of nano plankton. The latter factor is associated with Micula decussata, which is believed to represent the effect of solution at the sediment water interface. Both factors were used to develop a dissolution-sea level curve for nanno fossils. When combined with oxygen and carbon isotopes, this curve clearly shows that higher dissolution occurred during the late Campanian - early Maastrichtian time when {delta}{sup 18}O, {delta}{sup 13} C and TOC all had lower values. These correlations indicate a strong link between high sea levels, high temperatures and lower amount of continental organic debris. (author)

    Formation water is the water present in reservoir rock pores, produced together with petroleum. Usually it is hyper saline with concentrations that can be higher than 250 g/l of dissolved solids. The concentration of the dissolved elements and the isotopic composition of the water and of some of the dissolved elements can be excellent tracers to study the dynamic of underground fluid flux, the mixing of distinct sources and the origin of salinization of these waters. This work reports the isotopic composition ({delta}{sup 2}H , {delta}{sup 18}O) and electrical conductivity (EC) of formation waters from 10 wells of a petroleum field of the Reconcavo Basin, looking for their evolution, interaction with the minerals and rocks and reservoir interconnection. The samples have electric conductivity ranging from 84 to 137 mS/cm, with conductivity increasing with depth of production zone. It is observed an enrichment of deuterium and oxygen-18 with the depth of production zone, probably due to water-rock interactions that were probably increased by higher temperatures of the deeper levels and longer residence times. The samples from the production zone between 1450 to 1520 m, drained by 7 of the 10 wells sampled, show a small range in isotopic composition and in electric conductivity, indicating homogeneity in this level of the reservoir. In the shallow level of 450 m the values of {delta}{sup 2}H , {delta}{sup 18}O and EC are lower, with isotopic composition similar to the oceanic water, possibly representing the original water that entered the reservoir during the sedimentation of the basin.

    The establishment of the 'Petroleum Law' (Law No. 9.478/97) abolished the Exploration and Production State Monopoly in Brazil. Attaining concessions through the bidding rounds promoted by the Brazilian Petroleum Agency (ANP) became the only legal means for exploring and/or producing oil and natural gas in Brazil. In order to attract small and medium companies to this niche, inactive areas with marginal accumulations were offered by the Agency. These areas were returned to ANP by PETROBRAS. Currently, six small companies operate in the Reconcavo Oil Province, extracting and processing different types of oil. The available infrastructure is mostly deteriorated and obsolete. Additionally, there are serious limitations in the separation and storage capacity. This scenario resulted in the fragmentation of the old PETROBRAS production infrastructure. A possible solution to this problem could involve the establishment of a collective treatment unit which would work as a condominium. However, the operation of this plant must take into account the diversity of oils being produced in the Reconcavo Basin (physical-chemicals characteristics). This paper is aimed at (1) establishing a preliminary characterization of the different types of oil which will be delivered by local producers; (2) the critical variables for the oil model (it includes all oils received from different areas of the Reconcavo); (3) the identification of the main stake holders within this process; and (4) suggestions for operating models for the treatment unit taking into account the potential innovations and opportunities for R and D and spin-offs.

    To manage the increasing volume of produced water became one of the main challenges in the petroleum industry. PWRI (produced water re-injection) leads to a decrease operational cost in platforms, an increase in liquid flow rates on the topside facilities and a decrease in surface disposal of water. Nowadays in Brazilian fields for every barrel of produced oil three barrels of water need to be handled. PWRI is a process that has been widely diffused in many fields in the world. The main advantages of the PWRI are to reduce collected water, to decrease or eliminate surface disposal of produced water, and to help oil recovery. On the other hand, PWRI tends to increase corrosion when inappropriate materials in tubing and pipelines are used; increase souring potential due to the amount of nutrients for bacteria in the produced water; increase scale formation when sea-water and produced water are mixed and increase formation damage. Even in reservoirs with good qualities in terms of permeability and porosity, the poor quality of the reinjection water decreases injectivity. To minimize injectivity loss some requirements are important: to avoid solids in the produced water system, to inject above fracture propagation pressure to maintain injectivity whenever possible, to use compatible the chemical products for oil-water separation to avoid the formation solids-oil agglomerates.

    The Camamu and Reconcavo South Basins are located near the passive continental margin of the Bahia State, Brazil, and have high potential for hydrocarbon exploration. In these basins and surrounding basement, brittle and ductile structures were studied, which resulted in 3D stress field orientations by use of inversion methods. From this study, the following results are relevant: important control of the basement structural heritage on the basin formation and evolution; local strike-inversion of {sigma}{sub 1} and {sigma}{sub 3} orientations in transtensive settings; vertical {sigma}{sub 1} typical of extensional regime precedes sub horizontal {sigma}{sub 1} of transtensive one; in relation to basin's long axes, at least four main horizontal {sigma}{sub 1} orientations were obtained, involving parallel, orthogonal and two diagonal sets. This could be related to: parallel and orthogonal flexural stress due to the sedimentary load, local elastic rebound of fault blocks, stress channeling, density contrasts between oceanic and continental crusts and ridge pull of the adjacent oceanic plate; diagonals, due to a combination of first order regional and second order local stress fields. This suggest that the continental margin of the Bahia State evolves from a typical passive into a transtensive margin, with transpressive regime that have been observed in some places, in a classical evolution of the Wilson Cycle.

    A simulator for prediction of injectivity decline in perforated water injection wells is presented. The model parameters (filtration and formation damage coefficients) were determined from history data fitting, allowing injectivity decline prediction for various perforated water injectors. The injectivity model, considering both internal and external filtration, fitted the history data very well and allowed a comprehensive analysis of injectivity decline. The simulations revealed that, after the perforations filling, the injectivity decline rate becomes much more intensive. Therefore, the time necessary for perforations filling is an important variable on work over planning. (author)

    Magnetic Surveying Techniques are fully used in order to control the well path in drilling operations, and electronic tools, known as Measure While Drilling (MWD), uses the intensity and inclination of Earth's magnetic field as a reference for its inputs. These tools have three magnetometers and three accelerometers spaced 90 degrees apart which measure the components of magnetic field and gravitational field to calculate the inclination, the direction of the well, and the tool face orientation. Erroneous readings can occur due to the magnetic interference since the Earth magnetic field can be affected by external sources such as, magnetized materials in the BHA (axial), casings strings or near by wells (cross axial), and these abnormal readings are enough to put the well bore far away from its desired location. In this paper we intend to show the methodology and software usage to allow magnetic field strength exam and identification of systematic failures in mechanization or calibration of the electronics tools. Moreover, the use of enhancements as In-Field Referencing (IFR) or Interpolated In Field Referencing (IIFR) in sensors calculation are described. Furthermore, the results obtained comparing the solutions with gyroscope survey data is shown. (author)

    Air transportation of personnel to offshore oil platforms is one of the major hazards of this kind of endeavor. Pilot performance is a key factor in the safety of the transportation system. This study seeks to identify the ergonomic factors present in pilots' activities that may in some way compromise or enhance their performance, the constraints and affordances which they are subject to; and where possible to link these to their associated risk factors. Methodology adopted in this project studies work in its context. It is a merging of Activity Analysis (Guerin et al. 2001) of European tradition with Cognitive Task Analysis (CTA - www.ctaresource.com) articulated with the recent approaches to cognitive systems engineering developed by Professors David Woods and Erik Hollnagel. Fifty-five hours of field interviews provided the input for analysis. Sixteen ergonomic constraints were identified, some cognitive, some physical, all considered relevant by the research subjects and expert advisers. Although the safety record of the personnel transportation system studied is considered acceptable, there is low hanging fruit to be picked which can help improve the system's safety.

Chamo esta posição de macrorrealismo fenomenológico, em contraste com o microrrealismo científico. Qualidades da fenomenalidade não estão subjetivamente dentro do cérebro, mas objetivamente dentro de campos-experiência perceptuais extra-encefálicos, ou, como dizemos, lá fora no mundo.

    2015-06-01

    Reproductive adults in many bird species are assisted by non-breeding auxiliary helpers at the nest, yet the impact of auxiliaries on reproduction is variable and not always obvious. In this study, we tested Hamilton's rule and evaluated the effect of auxiliaries on productivity in the facultative cooperative breeder campo flicker ( Colaptes campestris campestris). Campo flickers have a variable mating system, with some groups having auxiliaries and others lacking them (i.e., unassisted pairs). Most auxiliaries are closely related to the breeding pair (primary auxiliaries), but some auxiliaries (secondary auxiliaries) are unrelated females that joined established groups. We found no effect of breeder quality (body condition) or territory quality (food availability) on group productivity, but the presence of auxiliaries increased the number of fledglings produced relative to unassisted pairs. Nonetheless, the indirect benefit of helping was small and did not outweigh the costs of delayed breeding and so seemed insufficient to explain the evolution of cooperative breeding in campo flickers. We concluded that some ecological constraints must limit dispersal or independent breeding, making staying in the group a "best-of-a-bad-job" situation for auxiliaries.

Este requería del esfuerzo con junto en mec´nica, óptica y electrónica, lo que facilitó la estructuración y el crecimiento de los respectivos grupos de trabajo, que posteriormente se integraron en departamentos En su origen (1977), el telescopio IAC80 fue concebido como un sistema clásico tipo Cassegrain, con una razón focal F/i 1.3 para el sistema Casse grain y una razón focal F/20 para el sistema Coudé. Posteriormente, aunque se mantuvo la filosofia de que el sistema básico fuera el F/11.3, se consideró conveniente el diseño de secundarios para razones focales F/16 y F/32, y se eliminó el de F/20. Sin embargo, dada la importancia relativa que un foco estrictamente fotográfico tiene en un telescopio moderno, diseñado básicamente para fotometría fotoeléctrica y con un campo util mínimamente de 40 minutos de arco, se decídió Ilevar a cabo el diseño de un secundario F/8 con un sistema corrector de campo, pero que estuviera formado únicamente por lentes con superficies esféricas para que asl su construcción fuera posible en España ó en México. La creciente utilización de detectores bidimensionales para fines de investigación astron6mica y la viabilidad de que en un futuro cercano éstos tengan un área sensible cada vez mayor, hicieron atractiva la idea de tener diseñado un sistema corrector de campo para el foco primario (F/3), con un campo útil mínimo de un grado, y también con la limitante de que sus componentes tuvieron sólamente supérficies esféricas. Ambos diseños de los sis-temas correctores de campo se llevaron a cabo, en gran medida, como parte de un proyecto de colaboración e intercambio en el área de diseño y evaluación de sistemas ópticos.

    The evolution of Lagoa Feia coquinas is analysed in its several stages, beginning with the exploratory phase. Special emphasis is devoted to the elements which contribute to improvement in geologic mapping. Development of the reservoir geology, interpretation of the factors that had influence in the reservoir pressure, communications between the fields, causing the low pressure, are discussed. The low transmissibility resultant from the heterogeneity created by the calcite and silica cementation are also reported. 11 figs., 7 refs

  13. Creencias tradicionales y campos electromagnéticos

    2011-09-01

    Full Text Available El autor propone que existe una serie de creencias y prácticas tradicionales que pueden proporcionar pistas acerca de la interacción de campos electromagnéticos en la biosfera. Por ejemplo, la creencia en el mal de ojo puede ser una construcción cultural relacionada con la sensación de estar siendo observado, pero a su vez puede estar basada en las emisiones de ondas electromagnéticas a través de los ojos. En este artículo se presentan datos para apoyar esta hipótesis. Otras creencias tradicionales, como la importancia de la conexión con la Madre Tierra también pueden contener una explicación similar. En este artículo se presentan una serie de hipótesis científicamente verificables sobre creencias tradicionales y campos electromagnéticos. En esta fase, los datos son insuficientes para confirmar la hipótesis, no obstante el objetivo de este artículo es estimular el pensamiento crítico y la investigación sobre algunas creencias tradicionales.

    Full Text Available Campo Quijano está a 30 Km. de la ciudad de Salta y cuenta aproximadamente con 8300 habitantes. En el éjido urbano existen dos borateras que constituyen una fuente puntual de contaminación del aire, suelo y aguas. Se estudió la prevalencia de enfermedades respiratorias en la población urbana en el año 2005. Se trabajó con los datos de las planillas de consultas diarias externas del Hospital Francisco Herrera. Se consideraron cuatro grupos de afecciones, seleccionados por la sintomatología y su posible asociación con las emisiones gaseosas de las borateras: Rinitis; Catarro en vías aéreas superiores, Espasmos y Tos irritativa. Se estimó y comparó la prevalencia de las enfermedades por barrio con la prueba de X2 y la de los residuales ajustados de Haberman. Los espasmos y catarros en vías aéreas superiores fueron las afecciones más frecuentes en la población de Campo Quijano. En rinitis no se encontraron diferencias entre barrios. El barrio San Roque presentó las mayores prevalencias en CVAs, espasmos y tos irritativa. Barrios cercanos a las borateras presentaron prevalencias dispares, lo que podría relacionarse con características socio-culturales, sanitarias y económicas, entre otros factores de riesgo, no considerados en este diagnóstico.

    After the end of the PETROBRAS monopoly in Brazil, the country started a new exploratory stage. Until the beginning of the pre-salt researches, the discovery of new oil mature fields was almost impossible. To take back the incentive to new researches about on-shore basins, without affect the focus on the off-shore basins, the Agencia Nacional de Petroleo, Gas Natural e Biocombustiveis (ANP) has been making efforts to increase the segment of oil medium and small size producers, who are called independent producers. To guarantee the good results, ANP has created auctions of mature and original fields of oil. The objective is to attract small and medium companies, so they can contribute to new technology of land exploration. The auctions have brought strength to the independent producers. The aim of this article is to show the case of Quiambina field, which belongs to the Campo-Escola Project, created by ANP in partnership with Universidade Federal da Bahia (UFBA) to revitalize the fields considered as matures, returned by PETROBRAS at the end of its monopoly era. To prove the economic viability of these mature shields, it will be used real values, get in the first four years of production. (author)

    Full Text Available Emission factors of natural processes and anthropogenic activities were used to estimate nutrients and metal loads for the lower Macaé river basin, which hosts the operational base for the offshore oil and gas exploration in the Campos Basin. The estimates indicated that emissions from anthropogenic activities are higher than natural emissions. Major contributing drivers include husbandry and urbanization, whose effluents receive no treatment. The increasing offshore oil exploration along the Brazilian littoral has resulted in rapid urbanization and, therefore might increase the inshore emission of anthropogenic chemicals in cases where effective residue control measures are not implemented in fluvial basins of the region.

    2015-06-01

    Full Text Available Ao norte do Maciço da Borborema, no Nordeste Brasileiro, vários campos de inselbergues caracterizam as depressões sertanejas. Esses relevos ocorrem principalmente em áreas de intrusões graníticas que atualmente estão sendo exumadas pela erosão diferencial. Em Quixadá, no estado do Ceará, ocorre um dos mais representativos campo de inselbergues do Brasil. Trata-se de diversas massas rochosas em geral côncavo-convexas ou fraturadas, formada pela exposição subaérea de um batólito granítico. Nesse trabalho, individualizamos as diversas formas de inselbergues agrupando-as segundo seus padrões morfológicos. Esses padrões foram correlacionados com as fáceis do granito e com a densidade de fraturamento. Observamos que as fáceis porfiríticas ricas em fenocristais de feldspato originaram inselbergues com feições de dissolução do tipo caneluras e vasques, enquanto as fáceis caracterizadas pela presença de diques e enclaves máficos originaram inselbergues caracterizados por feições de fraturamento do tipo taffonis de colapso. Essa correlação nos permitiu concluir que mesmo dentro de uma mesma unidade litológica como o granitoide, as variações faciológicas internas podem resultar em feições distintas de acordo com as características mineralógicas e texturais da rocha e do fraturamento.

    The Campo Formoso granite represents the magmatic phase of the remobilized Pre-Jacobina basement, located within an are defined by the Serra de Jacobina, north of Campo Formoso, Bahia. Intrusive relationships between this granite and the Jacobina Group metasediments, gradational changes in textures and compositions between the granite and basement rocks, and the general structural-topographic expression of this suggest a mantled gneiss dome model for this area. A RB/Sr whole rock isochron age of 1911 +- 13 m.y. for the Campo Formoso granite is established. This date is interpreted as the age of the development of the structure, as well as a minimum age for the Jacobina Group metasediments. K/Ar dates on muscovites from the Campo Formoso granite are concordant with the Rb/Sr isocron. It is suggested that a lower regional thermal gradient in the Campo Formoso area during Transamazonic time is the cause for a more rapid cooling environment. (Author) [pt

    With the aim to drill a horizontal well in the fault shadow zone, various techniques of time to depth conversion were used in a study to minimize the uncertainties. After removing some wells close to the fault and doing a conversion only based on VELAN (Velocities from Seismic Processing) the result had a considerable difference comparing to a conversion based on VELAN and wells. After this exercise, the confidence on the seismic cube was lost, especially for new projects close to the fault. To drill new wells in that region, a geologic model without the seismic was done to predict the depth values of the top of the reservoir. In addition, a new seismic in depth using the technique PSDM (Pre Stack Depth Migration) will be generated being taken into account that geological model. (author)

    Full Text Available Diante da crescente descaracterização do Bioma Cerrado em função da expansão da fronteira agropecuária na região central do Brasil, torna-se importante avaliar a capacidade de adaptação das espécies ao ambiente antropizado. Neste sentido, este trabalho foi desenvolvido com o objetivo de estimar e comparar a densidade populacional da raposa-do-campo Lycalopex vetulus (Lund, 1842 em duas áreas com diferentes graus de alteração, pastagem e campo sujo, em Campinápolis, Mato Grosso. Para tanto, no período entre agosto a novembro de 2005, foram efetuados censos noturnos ao longo de transectos lineares, totalizando percursos de 129,8 km na área de campo sujo e 62,08 km na área de pastagem. Estimativas de densidade populacional foram geradas utilizando o programa Distance 5.0, sendo que o modelo e ajuste mais adequados aos dados foram half-normal + hermite. Foram obtidas 23 e 52 detecções de raposas-do-campo nas áreas de campo sujo e pastagem, respectivamente. A densidade populacional de raposa-do-campo na área de pastagem (D=4,28 indivíduos/km²; IC=2,69 - 6,82 foi maior que na área de campo sujo (D=1,21 indivíduos/km²; IC=0,73 - 2,01, fato que deve estar relacionado, principalmente, com a disponibilidade de alimento e redução de potenciais predadores. Por apresentar uma dieta composta principalmente de cupins, especialmente os dos gêneros Syntermes e Cornitermes, a raposa-do-campo encontra na área de pastagem uma base alimentar abundante e estável. Além disto, a simplificação ambiental, em função da implantação de pastagens acaba por reduzir, ou até mesmo eliminar, animais que são potenciais predadores de raposas-do-campo, como Chrysocyon brachyurus (Illiger, 1815, favorecendo o aumento da densidade populacional da espécie neste tipo de ambiente. Por fim, características adaptativas apresentadas pela raposa-do-campo têm permitido que esta espécie sobreviva, inclusive apresentando elevada densidade

    Full Text Available O objetivo deste trabalho consistiu em avaliar sazonalmente a produção de sementes provenientes de fragmentos florestais presentes na zona rural de Campo Verde, MT. Essa caracterização ocorreu em termos de produção de sementes e riqueza de espécies vegetais. Foram selecionados três fragmentos florestais caracterizados como Floresta Estacional Semidecidual. Em cada fragmento, cinco coletores foram instalados e confeccionados com canos de PVC (1 m²; malha de náilon de 0,001 m e 0,15 m de profundidade do bojo. O material foi coletado mensalmente, cujas sementes foram quantificadas e separadas conforme a síndrome de dispersão, etapa sucessional e forma de vida. Houve a determinação da densidade, frequência absoluta, índice de diversidade e equitabilidade. Ao todo, foram obtidas 3.622 sementes, pertencentes a 74 táxons. Maiores densidades de sementes foram observadas durante os meses de setembro, outubro e novembro. As lianas Gouania sp., Fridericia speciosa, Heteropterys sp. e Distictella sp. responderam com 55,95% do total de sementes aportadas. Das espécies que compuseram a chuva de sementes, 74% não são dispersas pelo vento. Todavia, quando se verificou a quantidade de diásporos coletados, formas dispersas pelo vento foram predominantes, representando 76% do total. Citam-se como táxons arbóreos importantes para a recomposição florestal na região de Campo Verde, situada no Sudeste de Mato Grosso: Tachigali rubiginosa, Siparuna guianensis, Nectandra sp., Cordia alliodora, Alibertia sp., Terminalia brasiliensis e Myrcia sp. Essas espécies devem ser alvo de estudos mais específicos relacionados ao seu potencial para recuperação de ambientes degradados, considerando-se as Áreas de Preservação Permanente e Reservas Legais.

    Full Text Available The study of Cristina Campo’s translations offers a precious contribution to those of us who are attempting to investigate the unknown area that lies in the shadowy zone between the source text and its translation. Vittoria Guerrini, a rather solitary and reticent figure in 20th-century Italian literature, wrote under several pen names, of which her favourite was Cristina Campo, the masque she chose for her beautiful and intense translations of a small but significant collection of poems by John Donne. This paper aims at exploring Cristina Campo’s attitude towards translation and the unique relationship she established with the poets she translated. John Donne’s translations reflect a singular solidarity displaying points of affinity between two extremely complex personalities. The dialogic rapport abolishes difference in space and time, as well as difference in language, as author and translator testify the same supreme tension towards beauty, truth and perfection. Translation in this perspective is a sacred gesture of mediation.

    There are numerous applications given to clays including oil and water adsorbent, ceramic, whitening of beverages, porcelain, waste treatment, organic carrier molecules in cosmetics and pharmaceuticals, support for catalysts. In the pharmaceutical industry, the clays are used as excipients, diluents, desiccants, emulsifiers, to mask undesirable flavors, isotonic agent such as charger and delivery of active substances. These characteristics have contributed to the expansion of the search for applications of clay minerals in the cosmetic industry. The aim of this study was to determine the elemental composition of clays from Campos Gerais, Minas Gerais, with a view to their applicability in the production of cosmetics. The elements As, Ba, Br, Ce, Cl, Co, Cr, Cs, Eu, Fe, Hf, K, La, Lu, Na, Nd, Rb, Sb, Sc, Sm, Ta, Tb, Th,U, Yb and Zn were determined by neutron activation analysis and radionuclide activity concentration of 226 Ra, 228 Ra, 210 Pb and 40 K were determined by gamma spectrometry. It was verified that the activity concentration of radionuclides was in the same concentration as the global average, indicating that these samples do not present a risk of increased radiation exposure. The concentration of most elements determined is less than or equal to the overall mean concentrations, indicated by the values of Continental Upper Crust. (author)

    Full Text Available In this paper we present an example of a specific metric which geometrizes explicitly a light-like four-vector potential (chiral field. The geometrization shows that such a vector has the same geometrical structure as a gravitational Kerr field. We discuss a theoretical proposition that a rotating body generates, besides a special gravitational field, a magnetic-type gauge field which might be identified with a chiral geometrized field. This chiral field represents a novel type of field because we cannot identify it with any of the known electromagnetic fields. As an application of this theory we discuss the morphology of the planets around the sun.En este trabajo se presenta un ejemplo de una métrica especifica que geometriza explícitamente un potencial cuadrivector tipo luz (campo quiral. La geometrización muestra que tal vector tiene la misma estructura geométrica que un campo gravitacional Kerr.

  15. Energy and Mass Balance At Gran Campo Nevado, Patagonia, Chile

    Science.gov (United States)

    Schneider, C.; Kilian, R.; Casassa, G.

    The Gran Campo Nevado (GCN) Ice Cap on Peninsula Muñoz Gamero, Chile, is lo- cated in the southernmost part of the Patagonian Andes at 53S. It comprises an ice cap and numerous outlet glaciers which mostly end in proglacial lakes at sea level. The total ice covered area sums up to approximately 250 km2. GCN forms the only major ice body between the Southern Patagonian Icefield and the Street of Magallan. Its almost unique location in the zone of the all-year westerlies makes it a region of key interest in terms of glacier and climate change studies of the westwind zone of the Southern Hemisphere. Mean annual temperature of approximately +5C at sea level and high precipitation of about 8.000 mm per year lead to an extreme turn-over of ice mass from the accumulation area of the GCN Ice Cap to the ablation areas of the outlet glaciers. Since October 1999 an automated weather station (AWS) is run continuously in the area at Bahia Bahamondes for monitoring climate parameters. From February to April 2000 an additional AWS was operated on Glaciar Lengua a small outlet glacier of GCN to the north-west. Ablation has been measured at stakes during the same pe- riod. The aim of this study, was to obtain point energy and mass balance on Glaciar Lengua. The work was conducted as part of the international and interdisciplinary working group SGran Campo NevadoT and supported by the German Research Foun- & cedil;dation (DFG). Energy balance was calculated using the bulk approach formulas and calibrated to the measured ablation. It turns out, that sensible heat transfer is the major contribution to the energy balance. Since high cloud cover rates prevail, air tempera- ture is the key factor for the energy balance of the glacier. Despite high rain fall rates, energy input from rain fall is of only minor importance to the overall energy balance. From the energy balance computed, it was possible to derive summer-time degree-day factors for Glaciar Lengua. With data from the nearby

Some of these species also occur in campos rupestres on mountain ranges in Goiás state, campos de altitude (high altitude grasslands of the Serra do Mar, and on geologically homologous rocky formations of the Guyana shield. Species that were also recorded for distinct zonal formations like cerrado, caatinga and forests were excluded from the pattern. The campo rupestre-restinga disjunction proved valid for 9 of 56 investigated species (16%. Explanations put forth by different authors for this unusual disjunction pattern are compared in the light of geological and climatological evidence.Um padrão de distribuição disjunta entre as formações extrazonais conhecidas por campos rupestres na cadeia do Espinhaço e as restingas do litoral brasileiro vem sendo repetidamente proposto para algumas espécies de fanerógamas. Para averiguar a validade deste padrão, foram reunidos dados disponíveis em literatura e nos principais herbários. Verificou-se que algumas espécies aparecem adicionalmente nos campos rupestres das Serras de Goiás, campos de altitude da Serra do Mar, em formações rupestres geologicamente homólogas do Escudo das Guianas. Foram excluídas do padrão as espécies cuja ocorrência foi verificada também em vegetação zonal, tal como cerrado, caatinga e matas. O padrão campo rupestre-restinga se mostrou válido para 9 de 56 espécies investigadas (16%. As razões apresentadas por distintos autores para explicar este padrão peculiar de disjunção são comparadas à luz de evidências geológicas e climatológicas.

    Poynting's theorem is derived for complex electromagnetic fields without invoking the harmonic dependence of the fields. This reformulation yields the functional form of a continuity equation. The definition of poynting's vector for complex fields reduces to its traditional definition for real fields without involving an extra factor of 1/2. [Spanish] Se presenta la derivacion del teorema de Poynting utilizando una representacion compleja de los campos electromagneticos. En esta reformulacion se obtiene cabalmente la forma funcional de una ecuacion de continuidad. Este resultado no requiere que los campos armonicos sean trenes de onda infinitos, de manera que con este formalismo es posible abordar el caso de pulsos electromagneticos. La definicion del vector Poynting para campos complejos se reduce a la definicion convencional si los campos son reales sin involucrar un factor de 1/2 adicional.

  1. Comparison of the rift and post-rift architecture of conjugated salt and salt-free basins offshore Brazil and Angola/Namibia, South Atlantic

    Strozyk, Frank; Back, Stefan; Kukla, Peter A.

    2017-10-01

    This study presents a regional comparison between selected 2D seismic transects from large, conjugated salt and salt-free basins offshore southern Brazil (Campos Basin, Santos Basin, Pelotas Basin) and southwest Africa (Kwanza Basin, northern and southern Namibe Basin, Walvis Basin). Tectonic-stratigraphic interpretation of the main rift and post-rift units, free-air gravity data and flexural isostatic backstripping were used for a comprehensive basin-to-basin documentation of key mechanisms controlling the present-day differences in conjugated and neighbouring South Atlantic basins. A significant variation in the tectonic-sedimentary architecture along-strike at each margin and between the conjugated basins across the South Atlantic reflects major differences in (1) the structural configuration of each margin segment at transitional phase between rifting and breakup, as emphasized in the highly asymmetric settings of the large Santos salt basin and the conjugated, salt-free southern Namibe Basin, (2) the post-breakup subsidence and uplift history of the respective margin segment, which caused major differences for example between the Campos and Espirito Santo basins and the conjugated northern Namibe and Kwanza basins, (3) variations in the quantity and distribution of post-breakup margin sediments, which led to major differences in the subsidence history and the related present-day basin architecture, for example in the initially rather symmetric, siliciclastic Pelotas and Walvis basins, and (4) the deposition of Aptian evaporites in the large rift and sag basin provinces north of the Rio Grande Rise and Walvis Ridge, highly contrasting the siliciclastic basins along the margin segments south of the ridges. The resulting present-day architecture of the basins can be generally classified as (i) moderately symmetric, salt-free, and magma-rich in the northern part of the southern segment, (i) highly asymmetric, salt-bearing and magma-poor vs. salt-free and magma

Using the Evans' unified field theory, we show that the true unification of gravity and electromagnetism is with source-free Maxwell equations.Todo tensor métrico puede ser expresado por el producto interno de campos tetrados. Se prueba que las ecuaciones de Einstein para esos campos tienen la misma forma que el tensor electromagnético de momento-energía si la corriente externa total es igual a cero.

    The county of Campos dos Goytacazes, located in the north region of the State of Rio de Janeiro, currently is the leading red ceramic pole of the State. However, the clays are kaolinitic predominance with low amount of flux oxides as well as elevated loss on ignition. In this work compositions were investigated using of a clay from the county of Itaborai, that is approximately 200 km away from Campos, to correct the deficiencies of the clay from Campos and so to improve the the technological properties of the ceramic. Rectangular specimens were prepared by uniaxial mold-press at 18 MPa and then fired at 800 deg C. The evaluated physical and mechanical properties were: plasticity, linear shrinkage, water absorption and flexural rupture strength. The results indicated that the clay from Itaborai significantly improves the evaluated properties of the ceramic. (author)

O exemplo do campo dos economistas franceses, analisado a partir de um conjunto de entrevistas, observações de dados prosopográficos, revela certas características dessas lutas. Estas opõem detendores de formas diferenciadas de capital, que estão elas mesmas em correspondência com posições distintas no campo do poder. Nessas lutas, estão em questão ao mesmo tempo a autonomia e a estrutura desse campo científico. A fraca autonomia relativa do campo da ciência econômica se faz acompanhar de uma forte homologia entre a estrutura desse campo e aquela do campo do poder francês em seu conjunto.The concept of the economist, rather than being a simple and evident one, is the object of numerous conflicting definitions. The example of the field of French economists, as analysed in a set of interviews and the observation of prospographical data, reveal certain characteristics of these conflicts. These struggles oppose those who detain differentiated forms of capital, which are themselves in correspondence with distinct positions in the field of power. These conflicts put into question both the autonomy and the structure of this scientific field. The relatively weak autonomy of the field of economical sciences is followed by a strong homology between the structure of this field and that of the field of French power in its entirety.

  1. Ground-water in the Teresina-Campo Maior area, Piaui, Brazil

    Science.gov (United States)

    Rodis, Harry G.; Suszczynski, Edison F.

    1972-01-01

    The Teresina-Campo Maior area lies in a presently developing farming and grazing region near the margin of drought-prone northeast Brazil where irrigated farming offers the best potential for economic development. The area comprises 9,700 square kilometers largely of catinga-covered tabular uplands which are drained by the perennial Rio Parnatba. The climate is hot and humid most of the year but with distinct wet and dry seasons. Temperature extremes range from 20?C to 39?C and the annum rainfall averages 1,200 millimeters. The area's ground-water reservoir is contained chiefly in sandstone aquifers of six westward-dipping sedimentary rock formations, all part of the Maranhao sedimentary basin. The youngest of these formations, namely the Piaut (Pennsylvarian), Poti (Mississippian), Longa (Upper Devonian), and Cabecas (Middle Devoniar), contain the principal aquifers. Precipitation is the primary source of recharge to these aquifers and is more than sufficient to replenish current withdrawals from wells. Underlying the principal aquifers are the untapped Pimenteiras and Serra Grande Formations (both Lower Devonian) which in areas adjacent to the report area are moderately good to excellent water producers. These aquifers are recharged principally by lateral inflow from the east. Water also occurs in the alluvial deposits (Quaternary) underlying the flood plain of the Rio Parnatba but recurrent and uncontrolled flooding at present (1966) precludes their development. Of little economic importance, because they lie above the zone of saturation, are the thin erosional remnants of the Pastos Bons (Upper Triassic), Matuca, and Pedra de Fogo (both Permian) Formations. There are in the report area about 200 drilled wells most of which are pumped with power-driven engines. The wells range from 40 to 500 meters deep but most do not exceed 150 meters, and practically all are completed open hole. Yields range from 500 liters per day for 6-inch-diameter domestic wells to 240

    The Espirito Santo Basin integrates the group of basins along the eastern Brazilian continental margin. It is located between 18 deg and 21 deg S, encompassing an area of approximately 220,000 km{sup 2}, onshore and offshore the Espirito Santo State. Its geological limit with the Campos Basin to the south is defined by a Precambrian basement high (Vitoria Arch), and its northern limit with the Mucuri Basin is defined by a geopolitical limit. The study of salt tectonics processes in the Espirito Santo Basin allowed the deformational analysis and interpretation of the chronological evolution of the mini-basins developed between salt diapirs. We observe an intrinsic relationship between halokinesis and creation of subsidence troughs that may be important for trapping hydrocarbon reservoirs, and consequently form oil and gas accumulations in this portion of the basin. This geodynamics evolution of these structures is marked by a strong linkage between salt movement and coeval sedimentation in the interdomal basins, forming structures and stratigraphic traps that may constitute important aspects for the petroleum geology.

Within the context of this debate it is worth to stop at Max Aub's Laberinto mágico, which is a Spanish Civil War magnificent mural as well as one of the last manifestation of the pure model of national episode, Galdós and Valle Inclán's ultimate legacy. In spite of containing apparent heterogeneous elements, the historical and ideological signs in Campo cerrado (1939 are the ones of modern historical novel. In the following campos, Aub's historical-novel formula reached its maturity, Campo del moro (1963 possibly being the most brilliant and balanced example in this modality among the novels of the series. In it, the of history announced in, Campo del moro banishes away as a victim of treason and shocked by the madness that grows on Madrid's streets. Campo del moro could be considered a pure historical novel, since the necessary felicity conditions are accomplished, causing this genre to be completely fulfilled: historicity of the events and respect for the chronological order in which they occur; fiction limited by the historical referent; initiative of the historical events over fiction, and power of the public logic over the private; and last but not least, narrativity of the events manifestated in the selection of the golpe de estado of Casado and Besteiro and their enlightment as the key to the historical story. Three are the big issues that are presented in the argumental logic of the novel: treason, the confusion in the maze and the heroic cause degradation. ln Max Aub's speech, which feeds the novel, fiction, reality and history are weaved together to the point of creating Ariadna's in the Maze.

    Full Text Available Some water bodies in the Sinos River Basin (SRB have been suffering the effects of pollution by residential, industrial and agroindustrial wastewater. The presence of cytotoxic and genotoxic compounds could compromise the water quality and the balance of these ecosystems. In this context, the research aimed to evaluate the genotoxicity and cytotoxicity of the water at four sites along the SRB (in the cities of Santo Antônio da Patrulha, Parobé, Campo Bom and Esteio, using bioassays in fish and cell culture. Samples of surface water were collected and evaluated in vitro using the Astyanax jacuhiensis fish species (micronucleus test and comet assay and the Vero lineage of cells (comet assay and cytotoxicity tests, neutral red - NR and tetrazolium MTT. The micronucleus test in fish showed no significant differences between the sampling sites, and neither did the comet assay and the MTT and NR tests in Vero cells. The comet assay showed an increase in genetic damage in the fish exposed to water samples collected in the middle and lower sections of the basin (Parobé, Campo Bom and Esteio when compared to the upper section of the basin (Santo Antônio da Patrulha. The results indicate contamination by genotoxic substances starting in the middle section of the SRB.

    Full Text Available ABSTRACTWe studied the effects of seed storage on germination and dormancy alleviation in three species of Fabaceae endemic to campo rupestrein southeastern Brazil. Fresh seeds of Collaea cipoensis, Mimosa maguirei and Mimosa foliolosawere set to germinate and germination of seeds after four, five and 13 years of storage was tested. Seed viability was maintained for all species after the full storage period. Seed storage significantly increased germination percentage and decreased germination time for C. cipoensisand M. foliolosa, suggesting the alleviation of physical dormancy with storage. However, we did not find evidence of dormancy alleviation in M. maguirei since stored seeds showed a decrease in germination in comparison to that of fresh seeds. Our data indicate species-specific storage-mediated dormancy alleviation, which will have important implications for restoration of campo rupestre.

    With the exception of the salt-related rollover folds of the Brazilian Continental Margin, folds are not features commonly associated with extensional faults. N-S-trending folds are common features in the hanging wall or above the termination of normal basement faults of the pre, syn and post-rift sequences of the Campos and Santos basins. Regional compression, differential compaction and local transpression are interpreted as the main reasons to explain the formation of folds in the Brazilian margin. However, they can also be formed as a result of the interplay among kinematics, amount of slip and geometry of faults. Two main types of fault-related folds are strongly influenced by geometry and kinematics: fault-bend folds and fault-propagation folds. Fault-bend folds are flexures formed as a result of dip changes of the fault plane. The folds are formed by the collapse of the hanging wall block as it passes over the top of bends in the fault plane. Fault-propagation folds form when movement of basement faults propagates deformation above their tip into a stratified rift and/or post-rift sequence. In this case, the movement of the buried normal fault produces folding in the overlying rocks, without expressive rupture of the beds. Movement along these folds can be accompanied by flexural slip mechanisms, allowing their lateral migration away from the fault plane and the formation of fold swarms like those in the Campos and Santos basins. The strong geometrical relationships of fault-bend and fault-propagation folds not only facilitate the predictive interpretation of these structures in seismic sections, but also allow measurement of stretching, reservoir quality predictions and fracture intensity estimates. In the Campos and Santos basins, regional scale fault-bend and fault-propagation folds might be responsible for the structural control of basement highs and depressions, distribution and migration of depo centers, and location of fractured zones. Fold swarms

    Systemic sclerosis is an autoimmune disease which shows extreme heterogeneity in its clinical presentation and that follows a variable and unpredictable course. Although some discrepancies in the incidence and prevalence rates between geographical regions may reflect methodological differences in the definition and verification of cases, they may also reflect true local differences. To determine the prevalence and incidence of systemic sclerosis in the city of Campo Grande, state capital of Mato Grosso do Sul (MS), Brazil, during the period from January to December 2014. All health care services of the city of Campo Grande - MS with attending in the specialty of Rheumatology were invited to participate in the study through a standardized form of clinical and socio-demographic assessment. Physicians of any specialty could report a suspected case of systemic sclerosis, but necessarily the definitive diagnosis should be established by a rheumatologist, in order to warrant the standardization of diagnostic criteria and exclusion of other diseases resembling systemic sclerosis. At the end of the study, 15 rheumatologists reported that they attended patients with systemic sclerosis and sent the completed forms containing epidemiological data of patients. The incidence rate of systemic sclerosis in Campo Grande for the year 2014 was 11.9 per million inhabitants and the prevalence rate was 105.6 per million inhabitants. Systemic sclerosis patients were mostly women, white, with a mean age of 50.58 years, showing the limited form of the disease with a mean duration of the disease of 8.19 years. Regarding laboratory tests, 94.4% were positive for antinuclear antibody, 41.6% for anti-centromere antibody and 19.1% for anti-Scl70; anti-RNA Polymerase III was performed in 37 patients, with 16.2% positive.

    Full Text Available Cuando en la década de los sesenta se pusieron en marcha los Planes Nacionales de Desarrollo, la comarca del Campo de Gibraltar vivía una situación de pobreza y de analfabetismo, caracterizada por la servidumbre de su población al uso militar de gran parte de su territorio, y a la presencia de la colonia británica de Gibraltar. La calificación como Zona de Preferente Localización Industrial, hizo que en el Arco de la Bahía de Algeciras se instalara un conjunto de grandes empresas que han transformado sensiblemente la comarca, en términos de empleo, económicos e incluso de cualificación de los ciudadanos. Palabras-clave: Grandes industrias, Campo de Gibraltar, Planes de Desarrollo, Bahía de Algeciras.___________________________ABSTRACT:When in the sixties are launched the National Development Plans, in order to avoid regional imbalance, the region of Campo de Gibraltar suffered a socio-economic situation of poverty and illiteracy, which was characterized by the easement to military use of its territory, and the presence of the British colony of Gibraltar. Its classification as Industrial Location Preferred Zone was the cause of a set of large companies to be installed at the Bay of Algeciras, which have significantly transformed the situation in this area, in terms of employment, economy, and even their people´s qualification.Keywords: Large industries, Campo de Gibraltar, Development Plans, Bay of Algeciras

  9. Espacio y desaparición: los campos de concentración en Argentina

    Full Text Available The main goal of this article is to investigate how the use of forced disappearances in Argentina (1974-1983 caused modifications to the unique spatial characteristics of their concentration camps. Specifically, I analyze three aspects: the removal within the camps of spatial-temporal references to the disappeared persons, the manner in which these victims remain present within the camps despite their disappearance, and the manner in which the outside space penetrates and superimposes itself upon the camp. This analysis is upheld by personal in depth interviews I had in Tucumán with relatives of the Disappeared and with survivors of the concentration camps.

    Partiendo de la hipótesis de que la técnica aniquilación por desaparición forzada de personas en Argentina (1974-1983 reconfiguró el espacio; el trabajo que desarrollo en el presente artículo consiste en indagar acerca de las particularidades de la dimensión espacial en los campos de concentración en Tucumán. El análisis gira en torno a tres ejes centrales: la negación de las referencias espacio-temporales a los detenidos-desaparecidos dentro del campo; el modo en que los desaparecidos «a pesar de todo» se representan un espacio y un tiempo concentracionario; y por último, el modo en que superponen e interpenetran los espacios del afuera con el adentro del campo. Este trabajo de análisis se sustenta en entrevistas en profundidad que he realizado a familiares de desaparecidos y sobrevivientes de campos de concentración en Tucumán.

    2017-09-01

    Full Text Available This article focuses on the narrative of Humberto de Campos in his first volume of memoirs (1886-1900 with regard to the education of the author. The first section emphasizes the importance of autobiographical writing for research in History of Education, and especially in History of Mathematics Education. The second section is a brief presentation of Humberto de Campos as a Brazilian writer. The next part discusses the theoretical and methodological foundations adopted for the use of autobiographical sources in research. The core of the text consists of the approach of the main school experiences narrated by Humberto de Campos in Parnaíba, in the interior of the state of Piauí, in the 1890s, highlighting practices that involve mathematical knowledge. The writer’s school memories emphasize the material precariousness of elementary education, the simultaneous teaching of many students of different levels in schools managed by a single teacher and the teaching methods based on repetition and memorization and supported in practices of punishment and humiliation of students.

    Full Text Available En este trabajo se presentan los resultados obtenidos de la aplicación de Campos Magnéticos (CM tanto pulsados (CMP como estáticos (CME en la morfología de osteoblastos humanos. El efecto de dichos campos ha sido medido por medio del análisis de la estructura de la β-tubulina, la cual es una proteína que forma parte del citoesqueleto celular. El campo magnético aplicado fue de 0.65 mT en el caso del CMP y de 0.5 mT en el caso del CME. La aplicación de los CM provoca alteración en el patrón de distribución normal de las redes de microtúbulos, dando lugar a la formación de agregados fluorescentes en la región cortical de la membrana celular. Las observaciones obtenidas con respecto a loscambios morfológicos de los osteoblastos, indican claramente que éstos son sensibles a la estimulación con CM, alterando su actividad celular a través de cambios en la estructuradel citoesqueleto celular.In this work are presented the results obtained from the application of magnetic fields (MF, both pulsed (PMF and static (SMF, on the morphology of human osteoblasts. The effectof such fields has been evaluated through the analysis of the structure of the β-tubuline, which is protein that forms part of the cellular cytoskeleton. The applied fields were 0.65 m Tand 0.5 mT for PMF and SMF, respectively. The application of the MF produces alterations in the pattern of normal distribution of microtubules, which gives rise to the formation of fluorescent aggregates in the cortical region of the cellular membrane. The obtained results with respect to the morphological changes in the osteoblasts clearly suggest that these are sensitive to stimulation with MFs, which alter its cellular activity through changes in cytoskeletal structures.

    Full Text Available La noción de campo desempeñó un papel central en los proyectos científicos de Kurt Lewin y Pierre Bourdieu. En este artículo hacemos un análisis comparativo del uso teórico y metodológico que hicieron de este concepto en la producción de su fecunda obra en los campos de la psicología y de la sociología, respectivamente. Para ello nos hemos centrado en cinco cuestiones cruciales que de modo explícito plantearon estos dos investigadores en la elaboración de su teoría de campo: la ruptura con las objetivaciones parciales, la construcción del objeto, la dinámica interna de los campos, la delimitación de sus fronteras y la representación matemática de los hechos psicológicos y sociológicos. Concluimos con una síntesis en la que ponemos de relieve algunas importantes coincidencias y diferencias en la teoría de campo de Kurt Lewin y Pierre Bourdieu. Ambos le asignaron funciones epistemológicas similares, pero podemos apreciar en Lewin un mayor mimetismo respecto a la noción de campo proveniente de la física y sus posibilidades de formulación matemática, mientras que en Bourdieu la noción de campo es inseparable de las de habitus y capital, lo que facilita un análisis más integrado de los fenómenos micro y macrosociales, una apreciación más sofisticada de sus dimensiones temporales y criterios más precisos para establecer los límites de un campo.

    Relevant concentrations of a broad range of pollutants have been found in Spanish Mediterranean River basins, as consequence of anthropogenic pressures and overexploitation (Campo et al., 2014). In this study, the occurrence and sources of 21 perfluoroalkyl substances (PFASs) were determined in water and sediment of the Ebro and Guadalquivir River basins (Spain). PFASs are persistent, bio-accumulative and toxic, which make them a hazard to human health and wildlife. The Ebro and Guadalquivir Rivers are the two most important rivers of Spain. They are representative examples of Mediterranean rivers heavily managed, and previous researches have reported their high pesticide contamination (Masiá et al., 2013). Analytes were extracted by solid phase extraction (SPE) and determined by liquid chromatography coupled to tandem mass spectrometry (LC/MS-MS). In water samples, from 21 analytes screened, 11 were found in Ebro samples and 9 in Guadalquivir ones. In both basins, the most frequents were PFBA, PFPeA, PFHxS and PFOS. Maximum concentration was detected for PFBA, with 251.3 ng L-1 in Ebro and 742.9 ng L-1 in Guadalquivir. Regarding the sediment samples, 8 PFASs were detected in those coming from Ebro basin and 9 in those from Guadalquivir. The PFASs most frequently detected were PFBA, PFPeA, PFOS and PFBS. Maximum concentration in Ebro samples was detected for PFOA, with 32.4 ng g-1 dw, and in Guadalquivir samples for PFBA with 63.8 ng g-1 dw. Ubiquity of these compounds in the environment was proved with high PFAS concentration values detected in upper parts of the rivers. Results confirm that most of the PFASs are only partially eliminated during the secondary treatment suggesting that they can be a focal point of contamination to the rivers where they can bio-accumulate and produce adverse effects on wildlife and humans.

The use of gas micro-turbines, the application of SAGD (Steam Assisted Gravity Drainage), the use of the drilling technique for river crossing and to a proposal for a new system of the rig less workovers are approached. The focus is the search of the increment of the production, the increase of the factor of final recovery, the global reduction of the costs and the minimization of the environmental impacts. The volumes of heavy oils in Campos Basin and in national onshore areas they are significant and, therefore, techniques and procedures that optimize its production are strategic. In the Brazilian Northeast there are a series of small fields of low productivity, in general of heavy oils, some in production there are more than twenty years that need of a reduction of the cost for barrel to continue producing. A realistic and responsible posture with the use of probabilistics concepts, techniques of engineering of the reliability, adoption of 'tolerable' levels of risk (associate to the return), attendance on line of the sceneries, premises and criteria, (proposal of the methodology GERISK), are relevant factors that can propitiate not only the reduction of the cost for produced barrel as well as to take the an increase of the factor of final recovery of the field.

    Hydrographical basins are important from hydrological, economic and ecological points of view. They receive and channel the runoff from rainfall and snowmelt which, when adequate managed, can provide fresh water necessary for water supply, irrigation, food industry, animal husbandry, hydrotechnical arrangements and recreation. Hydrographical basin planning and management follows the efficient use of available water resources in order to satisfy environmental, economic and social necessities and constraints. This can be facilitated by a decision support system that links hydrological, meteorological, engineering, water quality, agriculture, environmental, and other information in an integrated framework. In the last few decades different modelling tools for resolving problems regarding water quantity and quality were developed, respectively water resources management. Watershed models have been developed to the understanding of water cycle and pollution dynamics, and used to evaluate the impacts of hydrotechnical arrangements and land use management options on water quantity, quality, mitigation measures and possible global changes. Models have been used for planning monitoring network and to develop plans for intervention in case of hydrological disasters: floods, flash floods, drought and pollution. MIKE HYDRO Basin is a multi-purpose, map-centric decision support tool for integrated hydrographical basin analysis, planning and management. MIKE HYDRO Basin is designed for analyzing water sharing issues at international, national and local hydrographical basin level. MIKE HYDRO Basin uses a simplified mathematical representation of the hydrographical basin including the configuration of river and reservoir systems, catchment hydrology and existing and potential water user schemes with their various demands including a rigorous irrigation scheme module. This paper analyzes the importance and principles of integrated hydrographical basin management and develop a case

    The Campos Basin is known as one of the most challenging deep water basins in the world. Currently there are thirty-seven platforms, more than a thousand oil wells, and about 4200 kilometers of submarine pipelines, having produced more than 1,2 billion barrels of oil per year and 15,7 million cubic meters of gas per day. The Campos Basin is responsible for more than 80% of Brazil's national production. Brazil intends to produce 2,2 million barrels of oil per day by 2007, when it will reach self-sufficiency. Therefore, the continued development of the offshore basins, such as Campos, Santos and Espirito Santo will be critical to meet this goal. In this context, the technological evolution of the vessels that render stimulation services is of fundamental importance to improve job quality, reduce time, protect with the environment, enable efficient communication, and ensure operational viability of new techniques. This paper reports on the history of this vessels, describing and illustrating new and state-of-the-art technology, historical cases of pioneering operations, data transmission in real time and the benefits for offshore operators with a global vision.

    1991-01-01

    Nine basin variables (shape, size and topology) have been analyzed in four small basins with non-permanent run off (SE of Spain). These geomorphological variables have been selected for their high correlation with the Instantaneous unit hydrograph parameters. It is shown that the variables can change from one small basin to another within a very short area; because of it, generalizations about the behaviour of the run off are not possible. In conclusion, it is stated that the variations in geomorphological aspects between different basins, caused mainly by geological constraints, are a very important factor to be controlled in a study of geoecological change derived from climatic change

    Old, climate-buffered infertile landscapes (Ocbils) have attracted increasing levels of interest in recent years because of their exceptionally diverse plant communities. Brazil's campos rupestres (rupestrian grasslands) are home to almost 15% of Brazil's native flora in less than 0.8% of Brazil's territory: an ideal study system for exploring variation in floristic diversity and phylogenetic structure in sites differing in geology and phytophysiognomy. We found significant differences in floristic diversity and phylogenetic structure across a range of study sites encompassing open vegetation and forest on quartzite (FQ) and on ironstone substrates, commonly termed canga . Substrate and physiognomy were key in structuring floristic diversity in the Espinhaço and physiognomy was more important than substrate in structuring phylogenetic diversity, with neither substrate nor its interaction with physiognomy accounting for significant variation in phylogenetic structure. Phylogenetic clustering was significant in open vegetation on both canga and quartzite, reflecting the potential role of environmental filtering in these exposed montane communities adapted to multiple environmental stressors. In forest communities, phylogenetic clustering was significant only at relatively deep nodes of the phylogeny in FQ while no significant phylogenetic clustering was detected across forest on canga (FC), which may be attributable to proximity to the megadiverse Atlantic forest biome and/or comparatively benign environmental conditions in FC with relatively deep, nutrient-rich soils and access to edaphic water reliable in comparison to those for open vegetation on canga and open or forest communities on quartzite. Clades representing relatively old lineages are significantly over-represented in campos rupestres on quartzite, consistent with the Gondwanan Heritage Hypothesis of Ocbil theory.

    In this study the process of co-pyrolysis of plastic polypropylene residues with gas-oil was evaluated, varying the temperature and the amount of polypropylene. The co-pyrolysis is a promising route to minimize the environmental impact caused by the inadequate plastic disposal, preventing its accumulation and giving a better use of the not renewable raw material (oil). The polypropylene samples and gas-oil were submitted to the thermal co-pyrolysis in inert atmosphere, varying the temperature from 400 deg C to 500 deg C and the amount of PP from 0,1 to 1,0 g. The influence of gas-oil was evaluated carrying the co-pyrolysis in the absence of PP. The pyrolyzed liquids produced by this thermal treatment had been characterized by modified gaseous chromatography objectifying the evaluation of the diesel fractions generation. As a result, the increase of PP amount lead to a reduction in the income of the pyrolytic liquid and to increase of the amount of solid generated. The effect of the increase of temperature showed an inverse result. The addition of PP in the reactor showed little interference in diesel range of distillation in the co-pyrolysis. On the other hand, an increase in temperature favors the increase of products in this range of distillation. The results show that plastic residue co-pyrolysis is a potential method of chemical recycling. (author)

Leaves showed uniseriate epidermis in petiole and leaf blade which contains uniseriate nonglandular tricomes (tector type occurring only over the vascular bundles. Likewise, paracytic stomata were found only in abaxial side of the leaf surface. The mesophyll contains uniseriate palisade parenchyma and multiseriate spongy parenchyma (nine layers which showed cells with different morphology and size. Crystal idoblasts of different types were observed in both the petiole and leaf blade. Collateral vascular bundles were found both in the petiole and leaf blade. Leaf venation type was pinnate, campylodromous or brochydodromous. The micromorphometric analysis showed significant differences from plants of different environments for all leaf characteristics and Cerrado plants showed higher means for all evaluated traits. Therefore, the influence of environments may had modulated morphological responses in P. rigida, since no difference was found in the type or distribution of leaf tissues in Cerrado or Campo Rupestre.

    PO 214 , a short life daughter product of RN 222 , was measured by alpha-ray spectrometry of a atmospheric particles sampled on Millipore filters (0.8 μm pore) at Sao Jose dos Campos (23 0 12'S, 45 0 51'W) and Cachoeira Paulista (22 0 41'S, 45 0 00'W). The infleunce of rainfall on the atmospheric Po 214 was studied at Sao Jose dos Campos. The mean activity was 98 pCi/m 3 for dry days (without rain during the preceding two days). On the contrary a low mean activity of 35 pCi/m 3 was observed for high pluviometry days from 08/30 to 10/26 for which total rainfall was 365.5 mm. At Cachoeria Paulista the Po 214 activity was correlated with the stability of the air (measured by the Richardson number), showing an accumaltion of natural radioactive aerosols during periods of higher stability of the lower atmosphere.

    Full Text Available O trabalho propõe uma releitura, confessadamente interessada e irônica, dos célebres esclarecimentos prestados por Malinowski no capítulo de abertura dos Argonautas do pacífico ocidental. Nesse texto, Malinowski expõe suas justificativas para o tipo de aproximação que realizou para estudar uma população melanésia da década de 1910, aproximação desde então consagrada na antropologia mediante a idéia de "trabalho de campo". Pretendo, de minha parte, demonstrar que as mesmas justificativas, colocadas dentro dos quadros propiciados por objetos bem diversos, podem fundamentar uma outra aproximação metodológica. Nesse sentido, continuar "fiel" a Malinowski significa relê-lo (e mesmo subvertê-lo de forma a explorar certas virtualidades de seu texto, acionadas com base em situações de pesquisa com que os antropólogos se deparam atualmente, permitindo adequar à disciplina metodologias que não se definem estritamente como "trabalho de campo". Essas reflexões assentam-se sobre uma trajetória pessoal caracterizada exatamente por pesquisas que privilegiaram materiais arquivísticos e fontes textuais.

    Full Text Available Este ensayo presenta una reflexión sobre la formación inicial de docentes a distancia dentro del campo de la educación en Colombia, principalmente desde la teoría de Pierre Bourdieu. La profesionalización del magisterio en Colombia ha sido un punto fundamental en la agenda educativa nacional, siendo las tres últimas décadas del siglo XX coyunturales para desarrollo de la metodología a distancia en programas de formación inicial docente a nivel universitario. A partir de entonces, la formación inicial de docentes a distancia ha tenido un posicionamiento dentro del campo de la Educación Superior en Colombia, hecho que se ha constituido en un agente profundo de cambio en la educación nacional y que ha estado claramente permeado por el impacto de las tecnologías de información y de la comunicación, lo cual le ha permitido enmarcarse dentro de los nuevos desafíos que dicha formación requiere.

    Full Text Available Si bien en Chile existen textos de carácter autobiográfi co desde la época colonial, hasta muy entrado el siglo XX estos apenas ocupan un lugar en la conformación del campo literario nacional, ya que son excluidos por críticos e historiadores de sus "panoramas" y catastros bibliográfi cos. Como en el resto de Hispanoamérica, descubrir estos relatos en su calidad de textos, esto es, más allá de su función documental, implica el reconocimiento de sus complejas estrategias discursivas y, en lo que respecta a su relación con la tradición autobiográfica europea, de sus frecuentes "desvíos de la letra". Resulta particularmente de interés observar la posición incómoda de sus cultores, quienes deben justifi car el empleo de la primera persona y la singularidad de su experiencia, en un medio en que prima la valoración del pudor. Frente a este juicio adverso, desarrollan tácticas para conseguir el perdón y beneplácito de sus lectores, en un campo literario en el que lentamente se va abriendo paso este tipo de producciones, de carácter moderno y subjetivo.

    Full Text Available To discuss sharp poetry of sound and visual expression, which shares the sense of renewing the old, but not strays from the old, or create the new, returning to the origin, is one of the main reasons of this article. More than baroque style in the twentieth century or break with the past, we investigated that the poets Haroldo de Campos, Augusto de Campos and Affonso Ávila share sharpness procedures that differ by participating in different discursive tenses, the baroque speech is one thing and the so called “new baroque” speech is another thing. Since then, the vanguard is no longer an operational category, but a point in the evolutionary line. We have thus a Haroldo de Campos that questions the literary history of Antonio Candido, proposing it not as a training but a transformation; less as a process that forms and more like a gerundive process, in which stand out the moments of rupture, understanding the tradition as a dialectical procedure, which puts diachrony and synchrony face to face. For exemplification of reflections we based on the poems “Oportet" by Haroldo de Campos and “Novo Novelo" by Augusto de Campos to discuss a recurrent theme in the literature: tradition and rupture, considering questionable the label "neo-baroque" in Brazilian literature.

    The Santos Basin was formed by rifting process during Mesozoic Afro-American separation. Sediment accumulation initiated with fluvial-lacustrine deposits, passing to evaporitic stage until reaching marginal basin stages. The analysis of hydrocarbon potential of Santos Basin identified two petroleum systems: Guaratiba-Guaruja and Itajai-Acu-Ilhabela. The Guaratiba Formation is less known in the Santos Basin because of small number of wells that have penetrated the rift section. By comparison with Campos Basin, hydrocarbons are of saline lacustrine origin deposited in Aptian age. Analogous to Campos Basin the major source rock is of saline-lacustrine origin, which has been confirmed from geochemical analyses of oil samples recovered from the various fields. These analyses also identified marine source rock contribution, indicating the Itajai-Acu source rock went through oil-window, particularly in structural lows generated by halokynesis. Models of hydrocarbon accumulation consider Guaratiba Formacao as the major source rock for shallow carbonate reservoirs of Guaruja Formacao and for late Albian to Miocene turbidites, as well as siliciclastic and carbonate reservoirs of the rift phase. Migration occurs along salt window and through carrier-beds. The seal rock is composed of shales and limestones intercalated with reservoir facies of the post-rift section and by thick evaporites overlying rift section, especially in the deeper water. In the shallow portion, shale inter-tongued with reservoir rocks is the main seal rock. The hydrocarbon generation and expulsion in the central-north portion of the basin is caused by overburden of a thick Senonian section. Traps can be structural (rollovers and turtle), stratigraphic (pinch-outs) and mixed origins (pinch-outs of turbidites against salt domes). (author)

  16. Atlantic Basin refining profitability

    Jones, R.J.

    1998-01-01

    A review of the profitability margins of oil refining in the Atlantic Basin was presented. Petroleum refiners face the continuous challenge of balancing supply with demand. It would appear that the profitability margins in the Atlantic Basin will increase significantly in the near future because of shrinking supply surpluses. Refinery capacity utilization has reached higher levels than ever before. The American Petroleum Institute reported that in August 1997, U.S. refineries used 99 per cent of their capacity for several weeks in a row. U.S. gasoline inventories have also declined as the industry has focused on reducing capital costs. This is further evidence that supply and demand are tightly balanced. Some of the reasons for tightening supplies were reviewed. It was predicted that U.S. gasoline demand will continue to grow in the near future. Gasoline demand has not declined as expected because new vehicles are not any more fuel efficient today than they were a decade ago. Although federally-mandated fuel efficiency standards were designed to lower gasoline consumption, they may actually have prevented consumption from falling. Atlantic margins were predicted to continue moving up because of the supply and demand evidence: high capacity utilization rates, low operating inventories, limited capacity addition resulting from lower capital spending, continued U.S. gasoline demand growth, and steady total oil demand growth. 11 figs

    During the past 25 years, industry and government made large financial investments that resulted in better water quality across the Nation; however, many water-quality concerns remain. Following a 1986 pilot project, the U.S. Geological Survey began implementation of the National Water-Quality Assessment (NAWQA) Program in 1991. This program differs from other national water-quality assessment studies in that the NAWQA integrates monitoring of surface- and ground-water quality with the study of aquatic ecosystems. The goals of the NAWQA Program are to (1) describe current water-quality conditions for a large part of the Nation's freshwater streams and aquifers (water-bearing sediments and rocks), (2) describe how water quality is changing over time, and (3) improve our understanding of the primary natural and human factors affecting water quality.The Upper Illinois River Basin National Water- Quality Assessment (NAWQA) study will increase the scientific understanding of surface- and ground-water quality and the factors that affect water quality in the basin. The study also will provide information needed by water-resource managers to implement effective water-quality management actions and evaluate long-term changes in water quality.

    Full Text Available É crescente a disponibilidade e utilização de campos de chuva estimados por sensoriamento remoto ou calculados por modelos de circulação da atmosfera, os quais são freqüentemente utilizados como entrada para modelos hidrológicos distribuídos. A distribuição espacial dos campos de chuva estimados é altamente relevante e deve ser avaliada frente aos campos de chuva observados. Este artigo propõe um método de comparação espaço-temporal entre campos de chuva observados e estimados baseado na comparação pixel a pixel e na construção de tabelas de contingência. Duas abordagens são utilizadas: (i a análise integrada no espaço gera índices de performance que retratam a qualidade do campo de chuva estimada em reproduzir a ocorrência de chuva observada ao longo do tempo; (ii a análise integrada no tempo produz mapas dos índices de performance que resumem a destreza das estimativas de ocorrência de chuva em cada pixel. Como exemplo de aplicação, é analisada a chuva estimada na climatologia do modelo global de circulação da atmosfera CPTEC/COLA sobre a bacia do Rio Grande. Utilizando-se cinco índices de performance, o método proposto permitiu identificar variações sazonais e padrões espaciais na performance das estimativas de chuva em relação a campos de chuva derivados de observações em pluviômetros.There is an increasing availability and application of precipitation fields estimated by remote sensing or calculated by atmospheric circulation models, which are frequently used as input for distributed hydrological models.

    From the Lagrangian formalism as in classical field theory, the partial differential field equations for the propagation of a small perturbation in a continuous and homogeneous conducting media in a magnetic field is obtained. The specific Lagrangian is calculated and it is shown that the equation of motion is the wave equation. Finally, the law of energy conservation is obtained. [Spanish] A partir de un formalismo lagrangiano, como el de la teoria clasica de campos, se obtienen las ecuaciones diferenciales de campo para la propagacion de un pequeno disturbio en un medio conductor continuo y homogeneo que se mueve en presencia de un campo magnetico uniforme. Usando el mismo marco teorico se obtiene la ecuacion de balance de energia. Se calcula la lagrangiana especifica y se demuestra que la ecuacion de movimiento es la ecuacion en onda. Ademas, se obtiene la correspondiente ley de la conservacion de la energia.

    The residual magnetism is a phenomenon in which the magnetic dipoles of a substance are oriented in a certain degree. On the other hand, when internal forces exist capable of aligning elementary magnetic dipoles of a material, a permanent magnet is obtained. Just as in a conductor or in a material, in the elements of a rotary electrical machine magnetic fields can be induced that produce a residual magnetism or magnetization. In the rotary electrical machines, the magnetization phenomenon causes serious problems, such as the generation of induced currents that propitiate the mechanical wear in bearings, collars, trunnions and inclusive in the shaft, by effects known as pitting, frosting and spark tracks, as well as erroneous readings in vibration and temperature sensors, that in some cases can cause the shut down of the machine. In this article are presented the general concepts on the residual magnetism in rotary electrical machines, the causes that originate it and the problems that arises, as well as the demagnetization of the components that have residual magnetic field. The results obtained by the area of Electrical Equipment of the Instituto de Investigaciones Electricas are revised, during the execution of activities related to the measurement and elimination of the residual magnetic field in rotary electrical machines. [Spanish] El magnetismo residual es un fenomeno en el que los dipolos magneticos de una sustancia se encuentran orientados en un grado determinado. Por otro lado, cuando existen fuerzas internas capaces de alinear los dipolos magneticos elementales de un material, se tiene un iman permanente. Al igual que en un conductor o un material, en los elementos de una maquina electrica rotatoria se pueden inducir campos magneticos que producen un magnetismo residual o magnetizacion. En las maquinas electricas rotatorias, el fenomeno de magnetizacion causa graves problemas, como la generacion de corrientes inducidas que propician el desgaste mecanico

    PETROBRAS Exploration and Production Business Unit in the State of Rio de Janeiro - PETROBRAS/UN-RIO has been developing environmental education actions as part of its environmental license process at Campos Basin. These actions are included in the project for the education of the multiplier groups in environmental education and core skills on environmental education. The goals of the project are either to create an integrated understanding of the environmental issue and a responsible conduction on natural resource and community values preservation. The multiplier groups are formed by associated professionals from the state government secretaries of education, health, environment and infra-structure areas. This Project has been developed at the north area of the State of Rio de Janeiro since 1999, in partnership of the Non Government Organization - NGO named 'Centro Norte Fluminense para Conservacao da Natureza - CNFCN'. Initial actions were based on a training course to prepare multiplier professionals on environmental education. In order to keep the multiplier Professional updated on environmental skills additional training course and local seminars are planned to be implemented in the region. Another project consider to create environmental skill cores to be implemented in the region based on training courses through either the use of the local public schools facilities and the volunteer contribution of the multiplier professionals.

    Full Text Available Herein, we report tick species found on wild and domestic animals and in the environment during a one-year sampling period at the Brazilian Farming Research Company beef cattle unit (Embrapa Beef Cattle, which is located within the urban area of Campo Grande, Mato Grosso do Sul, Brazil. From 55 wild hosts including six different species (Nasua nasua, Cebus spp., Cerdocyon thous, Myrmecophaga tridactyla, Tamandua tetradactyla and Dasyprocta aguti, 323 ticks were collected. Amblyomma ovale ticks were found solely on coatis, and Amblyomma nodosum was identified solely on anteaters. No ticks were found on capuchin monkeys. However, Amblyomma cajennense was found on all parasitized host species with the exception of capuchin monkeys. Giant anteaters displayed the highest infestation abundance, with a mean of 53 ticks∕animal. Environmental sampling yielded 166 adult A. cajennense ticks. The tick species found on domestic animals (Rhipicephalus (Boophilus microplus, R. sanguineus, Dermacentor nitens and A. cajennense were those typically found on these hosts in Brazil. The most prevalent tick species, A. cajennense, was found on both wild and domestic animals and was also prevalent in the environment. Thus, this tick species is the primary vector that allows pathogens to bridge wild and domestic animals in the Cerrado.Neste trabalho são descritas as espécies de carrapatos de animais selvagens e domésticos e do ambiente coletados por um ano na EMBRAPA Gado de Corte localizado na área urbana de Campo Grande, Mato Grosso do Sul, Brasil.

Its history and its relations with the local memory have created its own identity in the system of public spaces of the district. Originally designed by Burle Marx as a space surrounding the textile industry Tecelagem Parahyba, the park has been appropriated by the population of the area, going from the condition of private to public space and assuming an identity of public park of the city .It is proposed to discuss the reasons why a park initially part of a private property has extended its uses to the sphere of public life and also to understand its role in the context of the landscape architecture in the city.

    Full Text Available Las emociones han adquirido una importancia creciente en nuestra época, en todos los ámbitos de la sociedad. Esta revalorización de la dimensión afectiva de la persona se ha reflejado, a su vez, en su inclusión como objeto de estudio en investigaciones de numerosas ramas del saber. También dentro de los estudios en Comunicación, y en concreto en relación con la tecnología digital, existe un interés académico por las emociones. Por medio de una profunda revisión bibliográfica, en este trabajo se traza un mapa del campo de estudio en el que convergen las emociones y la tecnología digital; más concretamente, en el uso de Internet. En él se advierte un campo de investigación vibrante, amplio y complejo, en el que confluyen aproximaciones de diferente tipo, tanto en el plano teórico como en el metodológico. El artículo presenta un panorama de las investigaciones realizadas en esta materia, que abarca desde el estudio de las redes sociales como espacios de interacción en el que las emociones son expresadas, el contagio emocional a gran escala o el análisis de sentimientos en las plataformas digitales. Se concluye que la Red no sólo despierta emociones en sus usuarios y sirve de cauce para la expresión de los afectos, sino que también influye en el modo en que dicho afecto se modula y despliega, así como en la configuración de la identidad de la persona.

  4. Misrepresenting the Jordan River Basin

    Full Text Available This article advances a critique of the UN Economic and Social Commission for West Asia’s (ESCWA’s representation of the Jordan River Basin, as contained in its recently published Inventory of Shared Water Resources in Western Asia. We argue that ESCWA’s representation of the Jordan Basin is marked by serious technical errors and a systematic bias in favour of one riparian, Israel, and against the Jordan River’s four Arab riparians. We demonstrate this in relation to ESCWA’s account of the political geography of the Jordan River Basin, which foregrounds Israel and its perspectives and narratives; in relation to hydrology, where Israel’s contribution to the basin is overstated, whilst that of Arab riparians is understated; and in relation to development and abstraction, where Israel’s transformation and use of the basin are underplayed, while Arab impacts are exaggerated. Taken together, this bundle of misrepresentations conveys the impression that it is Israel which is the main contributor to the Jordan River Basin, Arab riparians its chief exploiters. This impression is, we argue, not just false but also surprising, given that the Inventory is in the name of an organisation of Arab states. The evidence discussed here provides a striking illustration of how hegemonic hydro-political narratives are reproduced, including by actors other than basin hegemons themselves.

  6. Marketing San Juan Basin gas

    Marketing natural gas produced in the San Juan Basin of New Mexico and Colorado principally involves four gas pipeline companies with significant facilities in the basin. The system capacity, transportation rates, regulatory status, and market access of each of these companies is evaluated. Because of excess gas supplies available to these pipeline companies, producers can expect improved take levels and prices by selling gas directly to end users and utilities as opposed to selling gas to the pipelines for system supply. The complexities of transporting gas today suggest that the services of an independent gas marketing company may be beneficial to smaller producers with gas supplies in the San Juan Basin

    1996-01-01

    Recent dramatic expansion of the natural gas industry in the Western Canada Sedimentary Basin provided ample proof of the potential of this area for further development of natural gas supply. However, the inherent competitive advantages provided by the Western Canada Sedimentary Basin were said to have been offset by low netback prices resulting in poor producer economics when competitiveness is measured by availability of opportunities to find and develop gas supply at costs low enough to ensure attractive returns. Technology was identified as one of the key elements in improving basin competitiveness, but the greatest potential lies in reduced transportation costs and increased access to North American market centres. 8 figs

    The anthropogenic activity on the surface can modify and introduce new mechanisms of recharging the groundwater system, modifying the tax, the frequency and the quality of recharge of underground waters. The understanding of these mechanisms and the correct evaluation of such modifications are fundamental in determining the vulnerability of groundwater contamination. The groundwater flow of the South Paraíba Compartment, in the region of São José dos Campos, São Paulo, is directly related to structural features of the Taubaté Basin and, therefore, the analysis of its behaviour enhances the understanding of tectonic structure. The methodology adopted for this work consists in pre-processing and processing of the satellite images, visual interpretation of HSI products, field work and data integration. The derivation of the main structural features was based on visual analysis of the texture elements of drainage, and the relief in sedimentary and crystalline rocks. Statistical analysis of the feature densities and the metric-geometric relations between the analysed elements have been conducted. The crystalline rocks, on which the sediments were laying, conditions and controls the structural arrangement of sedimentary formations. The formation of the South Paraíba Grabén is associated with Cenozoic distensive movement which reactivated old features of crust weakness and generated previous cycles with normal characteristics. The environmental analysis is based on the integration of the existing methodology to characterise vulnerability of an universal pollutant and density fracture zone. The digital integration was processed using GIS (Geographic Information System) to delineate five defined vulnerability classes. The hydrogeological settings were analysed in each thematic map and, using fuzzy logic, an index for each different vulnerability class was compiled. Evidence maps could be combined in a series of steps using map algebra.

    Based on geohydrologic information reported by Comision Nacional del Agua, Comision Federal de Electricidad and several academic institutions, we have performed an analysis to establish in general terms, the past and present behavior of the shallow aquifer in the Cerro Prieto geothermal zone (CPGZ). The main features of the aquifer, derived from the interpretation of the results obtained with several disciplines, are as follows: The shallow aquifer in CPGZ is part of the regional hydrologic system of the Mexicali valley basin. The basin is filled with unconsolidated delta deposits interbedded with alluvial sediments from the Sierra Cucapa, which forms an impervious boundary. Because the lack of information about the hydraulic properties of the sediments, just possible ranges of values were obtained for the hydraulic conductivity and storativity corresponding to three deposit environments: a) delta flood plain facies, b) estuarine or lagoon environment facies, c) distal alluvial fan facies.

    Species richness and seasonal abundance of solitary bees were investigated in rocky, montane grassland (campo rupestre) (1180 m asl) and cerrado sensu stricto (680 m asl) in the Biribiri State Park, Diamantina, state of Minas Gerais, Brazil. Three hundred nineteen nest traps of bamboo canes and black cardboard tubes were monthly inspected at each site during 15 months. A total of eight species of bees built 97 nests. Four species were common to both sites. Tetrapedia aff. curvitarsis Friese and Tetrapedia aff. peckoltii Friese were the most abundant at campo rupestre and cerrado s.s., respectively, followed by Centris analis (Fabricius) in campo rupestre and Centris tarsata Smith in cerrado s.s. The nesting peaks occurred in May in campo rupestre and in February in cerrado s.s. Three cuckoo bees and one bee-fly were collected as natural enemies. The findings suggest that differences between the sites were related more to ecological factors (floral resources, natural nest sites) than to the altitudinal difference. The species richness was similar to that in other habitats with open vegetation. We demonstrate the need to use several types of trap-nest to increase the range of species sampled; some species used only one of the two types traps provided. We also comment on the limitations of trap-nests in cerrado vegetation. Most cerrado species of bees are very selective in their choice for a nesting site, but bees that use trap-nests are more generalists.

    Oil fields accounting for a large portion of the world reserves are severely affected by biological degradation. In Brazil, giant fields of the Campos Basin are producing biodegraded oils with widely variable fluid characteristics (10 to 40 deg API) and no apparent logical distribution nor predictability. Modern geochemical techniques allow defining the level of biodegradation. When original (non-degraded) oil samples and other with varying degradation level are available it might be possible to define a distribution trend and to relate it to present day geological factors such as temperature and reservoir geometry. However, other critical factors must be taken into account. But most of all, it is fundamental to have a vision in time of their evolution. This can only be achieved through 3D Basin Models coupled with modern visualization tools. The multi-disciplinary work-flow described here integrates three-dimensional numerical simulations with modern geochemical analyses. (author)

    Full Text Available La electro-ósmosis es el fenómeno físico por el cual una variación de potencial eléctrico, da lugar a una circulación de fluido. El fenómeno recíproco que genera una corriente eléctrica a partir de un gradiente de presión en el fluido, recibe el nombre de electro-filtración. La razón entre las variaciones de potencial y las variaciones de presión representa al coeficiente de acoplamiento electrocinético. Recién en 1999, se realizó una prueba de campo con propósitos exploratorios, donde las ondas sísmicas se generaron a partir de una fuente electromagnética. En el presente trabajo se explica el por qué de estos efectos electrosísmicos o sismoeléctricos, según sea la fuente de origen electromagnético o mecánico, respectivamente. Se presentan las ecuaciones de Maxwell y de Biot acopladas que gobiernan los fenómenos y se analizan los coeficientes de transporte que son la conductividad eléctrica, el coeficiente de acoplamiento electrocinético y la permeabilidad. Es posible hacer ciertas suposiciones que permiten resolver un conjunto de ecuaciones simplificadas donde las respuestas electromagnéticas y las respuestas poroviscoélasticas pueden determinarse unas de otras en forma independiente. En el tratamiento de las ecuaciones de Maxwell se sigue la forma usual de descomponer el campo eléctrico y el campo magnético en campos primarios (o principales que se hallan analíticamente y campos secundarios, como perturbaciones de los primarios, que se calculan numéricamente. Trabajar en el dominio espacio-frecuencia, permite incorporar la naturaleza disipativa del medio poroso en la propagación de las ondas mecánicas, reemplazando los módulos elásticos reales por módulos complejos. Así mismo, se destaca la necesidad de establecer una grilla de cálculo adecuada para representar correctamente los gradientes de presión en el fluido a partir del skin-depth difusivo que se corresponde con la onda lenta de Biot.

  5. Sustaining Exploration in Mature Basins

    Exploration is a business like any other business driven by opportunity, resources and expectation of profit. Therefore, exploration will thrive anywhere the opportunities are significant, the resources are available and the outlook for profit (or value creation) is good. To sustain exploration activities anywhere, irrespective of the environment, there must be good understanding of the drivers of these key investment criteria. This paper will examine these investment criteria as they relate to exploration business and address the peculiarity of exploration in mature basin. Mature basins are unique environment that lends themselves a mix of fears, paradigms and realities, particularly with respect to the perception of value. To sustain exploration activities in a mature basin, we need to understand these perceptions relative to the true drivers of profitability. Exploration in the mature basins can be as profitable as exploration in emerging basins if the dynamics of value definition-strategic and fiscal values are understood by operators, regulators and co ventures alike. Some suggestions are made in this presentation on what needs to be done in addressing these dynamic investment parameters and sustaining exploration activities in mature basins

Pretende realçar a importância da reflexão teórica, não apenas como meio de circunscrever um campo de ação válido em relação à preservação dos bens culturais, como também de orientar o estabelecimento de uma adequada metodologia de intervenção, para que as decisões tomadas sejam fruto de considerações fundamentadas e judiciosas, compatíveis com a responsabilidade das quais estão imbuídas, e a fim de serem garantidas as condições de preservação das memórias individuais e coletivas, das quais os conjuntos urbanos e edifícios são a materialização. Não se trata de defender a adoção de um endereço teórico específico, mas de enfatizar a necessidade da reflexão teórica como parte intrínseca do fazer restauro, que não pode ser reduzido a uma ação de natureza unicamente técnica, mas deve ser visto como um problema de natureza histórico-crítica a ser resolvido.

    New livestock production models need to simultaneously meet the increasing global demand for meat and preserve biodiversity and ecosystem services. Since the 16th century beef cattle has been produced on the Pampas and Campos native grasslands in southern South America, with only small amounts of external inputs. We synthesised 242 references from peer-reviewed and grey literature published between 1945 and mid-2015 and analysed secondary data to examine the evidence on the ecosystem services provided by this grassland biodiversity hotspot and the way they are affected by land use changes and their drivers. The analysis followed the requirements of systematic review from the PRISMA statement (Moher et al 2009 Acad. Clin. Ann. Intern. Med. 151 264-9). The Pampas and Campos provide feed for 43 million heads of cattle and 14 million sheep. The biome is habitat of 4000 native plant species, 300 species of birds, 29 species of mammals, 49 species of reptiles and 35 species of amphibians. The soils of the region stock 5% of the soil organic carbon of Latin America on 3% of its area. Driven by high prices of soybean, the soybean area increased by 210% between 2000 and 2010, at the expense of 2 million ha (5%) of native grassland, mostly in the Pampas. Intensification of livestock production was apparent in two spatially distinct forms. In subregions where cropping increased, intensification of livestock production was reflected in an increased use of grains for feed as part of feedlots. In subregions dominated by native grasslands, stocking rates increased. The review showed that land use change and grazing regimes with low forage allowances were predominantly associated with negative effects on ecosystem service provision by reducing soil organic carbon stocks and the diversity of plants, birds and mammals, and by increasing soil erosion. We found little quantitative information on changes in the ecosystem services water provision, nutrient cycling and erosion control

  9. El intelectual y el campo cultural. Una variación sobre Bourdieu

    2007-08-01

    Full Text Available Within the field of the sociology of intellectuals there are many works dealing with the relationship between politics and the intelligentsia. In the past few years, Bourdieu’s work has pushed it again to the frontline. In this article, therefore, I shall argue that some of the theoretical instruments provided by the author of Distinction may help to analyse systematically and with some precision the connections between the field of specialised cultural production and the political field. Later on, I shall also argue that, although Bourdieu’s work clarifies key aspects of this relationship, at some points his conceptual framework seems to be somehow problematic. Making use of other authors, such as Max Weber and Quentin Skinner, I shall elaborate an interpretation of the connections between cultural producers and the political debate that challenges some of the central elements sustaining the bourdieuan vision.

    En el ámbito de la sociología de los intelectuales existen innumerables trabajos donde se analiza la relación entre la intelectualidad y la política. En los últimos tiempos, la obra de Pierre Bourdieu retomó este interés. En este trabajo propongo que algunos de los instrumentos teóricos proporcionados por el autor de La distinción pueden ser de gran ayuda para analizar las conexiones, sin duda escurridizas, que existen entre el campo de la producción cultural especializada y el campo de la política. Más adelante afirmo que, aunque la obra de Bourdieu clarifica aspectos muy importantes de esta relación, en algunos momentos su marco conceptual resulta problemático. Recurriendo a la obra de otros autores, como Max Weber o Quentin Skinner, en este artículo propongo una interpretación de la relación entre los productores culturales y el debate político que modifica aspectos fundamentales de la visión de Bourdieu.

  10. La educación popular: campo de acción profesional del trabajador social

    Full Text Available La educación popular, constituye un campo de acción donde se desenvuelve el trabajador social, actuando en los contextos familiares, institucionales, comunitarios, populares y en los sistemas sociales donde vive y aprende la gente, diseñando e impartiendo habilidades sociales y cognitivas, que permite al participante tomar decisiones en pro de su bienestar social. El propósito del presente estudio está referido a analizar la educación popular como campo de acción profesional para el trabajador social. La importancia del mismo estará en función de aportar a la formación de este profesional, herramientas teóricas para que esté en capacidad de ser crítico, investigador e innovador en los procesos de educación no formal que tendrá, por sus roles, que asumir. Esta investigación tiene un carácter documental. Para tal fin se consultaron autores como: Aguayo (1992, Carballeda (2002, Dussel (1998, Freire (1993, Gadotti (1991, Kisnerman (1990, Medina (1995, Puyol y Hernández (2009, Viscarret (2007, Habermas (1987, entre otros Entre las conclusiones más resaltante se destacan: Los procesos de educación popular no son neutros al igual que la acción del trabajador social y esto va a depender de la posición que se asuma. Desde el interés técnico, el rol de educador popular, será mediático, para mantener y conservar lo que está dado, la participación que se generará será acrítica, pasiva y no creativa. A lo cual Freire hace una fuerte crítica. Desde el interés práctico, la acción del trabajador social sería transformadora, pues promovería un tipo de participación crítica, reflexiva e interpretativa. Y desde el interés emancipador, la acción de este profesional tenderá a ser transformadora y revolucionaria, logrando una participación comprometida, consciente, autorreflexiva y responsable. Lo planteado no es independiente de las necesidades de los participantes y el trabajador social (educador popular difícilmente podr

    Full Text Available Si bien en Chile existen textos de carácter autobiográfico desde la época colonial, hasta muy entrado el siglo XX estos apenas ocupan un lugar en la conformación del campo literario nacional, ya que son excluidos por críticos e historiadores de sus “panoramas” y catastros bibliográficos. Como en el resto de Hispanoamérica, descubrir estos relatos en su calidad de textos, esto es, más allá de su función documental, implica el reconocimiento de sus complejas estrategias discursivas y, en lo que respecta a su relación con la tradición autobiográfica europea, de sus frecuentes “desvíos de la letra”. Resulta particularmente de interés observar la posición incómoda de sus cultores, quienes deben justificar el empleo de la primera persona y la singularidad de su experiencia, en un medio en que prima la valoración del pudor. Frente a este juicio adverso, desarrollan tácticas para conseguir el perdón y beneplácito de sus lectores, en un campo literario en el que lentamente se va abriendo paso este tipo de producciones, de carácter moderno y subjetivo.Even though there are texts of an autobiographical nature in Chile that date from Colonial times, they are not considered part of the national literary field until well into the XX Century; quite the opposite, they are excluded from overviews and bibliographical registries by critics and historians. Like in the rest of Spanish America, discovering autobiographical accounts as texts in their own right (that is, beyond their documental function, implies the recognition of their complex discursive strategies and becoming aware of the ‘deviation from the letter’ these texts represent when it comes to their relationship with the European autobiographical tradition. It is interesting to note the awkward position of authors of this literary field, who must justify the use of the first person and the singularity of their experience in an environment which strongly values decency.

  12. RESERVES IN WESTERN BASINS PART IV: WIND RIVER BASIN

    1998-04-01

    Vast quantities of natural gas are entrapped within various tight formations in the Rocky Mountain area. This report seeks to quantify what proportion of that resource can be considered recoverable under today's technological and economic conditions and discusses factors controlling recovery. The ultimate goal of this project is to encourage development of tight gas reserves by industry through reducing the technical and economic risks of locating, drilling and completing commercial tight gas wells. This report is the fourth in a series and focuses on the Wind River Basin located in west central Wyoming. The first three reports presented analyses of the tight gas reserves and resources in the Greater Green River Basin (Scotia, 1993), Piceance Basin (Scotia, 1995) and the Uinta Basin (Scotia, 1995). Since each report is a stand-alone document, duplication of language will exist where common aspects are discussed. This study, and the previous three, describe basin-centered gas deposits (Masters, 1979) which contain vast quantities of natural gas entrapped in low permeability (tight), overpressured sandstones occupying a central basin location. Such deposits are generally continuous and are not conventionally trapped by a structural or stratigraphic seal. Rather, the tight character of the reservoirs prevents rapid migration of the gas, and where rates of gas generation exceed rates of escape, an overpressured basin-centered gas deposit results (Spencer, 1987). Since the temperature is a primary controlling factor for the onset and rate of gas generation, these deposits exist in the deeper, central parts of a basin where temperatures generally exceed 200 F and drill depths exceed 8,000 feet. The abbreviation OPT (overpressured tight) is used when referring to sandstone reservoirs that comprise the basin-centered gas deposit. Because the gas resources trapped in this setting are so large, they represent an important source of future gas supply, prompting studies

    Decision analysis applied to the development phase of petroleum fields must take into account the risk associated to many kinds of uncertainties. In the transition of the appraisal to the development phases, the importance of risk associated to the production and the recovery factor may increase significantly. The process is complex due to high investments, large number of uncertain variables and strong dependence of the results with the production strategy definition. In E and P, several decisions must be taken considering the risks involved through the appraisal of the uncertainties impact in production of petroleum fields, increase the possibility of success, measuring possible lost and sub-optimized developments identifying new opportunities. In a specific scenario, like gas production, the risk associated to the project becomes larger due to the gas prices compared to oil, the demand, the distribution's structure and the deadlines defined in contracts. The objective of this paper is to show the results of a methodology developed in a detailed study of a risk analysis process in appraisal and development phases (execution and implementation) to one of the biggest gas fields in Brazil (Mexilhao Field) and support reliable future decisions.

    2004-07-01

    The integrated reservoir analysis of the Agulha field has led to several alternative actions to improve oil recovery, despite the fact that the field has already produced more than 45% of the currently mapped oil in place in nearly three decades. Studies were carried out taking into account not only elements of production behavior, but also the geologic aspects of the productive zones. Among various proposed actions, the following can be outlined: change of the water injection quota; workover for improvement of the swept efficiency; modification of the production schedule of some wells; improvement on the efficiency of the gas lift system. Additionally, the possibility that some wells be systematically producing from some hydrocarbon accumulations in volcanic rocks (not classified as reservoir yet), which is feeding traditional turbidities reservoirs is also investigated. The use of geochemical saturation, image and cement logs may lead to identify new oil producing horizons, including non-conventional reservoirs. In order to support new ideas on reservoir geometry and subsequent modeling, a new seismic acquisition is proposed. (author)

    PETROBRAS has recently begun active drilling on locations where the interest zone is below salt formations, which can be as thick as 2000 meters, formation that may contain mobile salts as taquihydryte. This paper refers to the slurries used on the first well drilled under those conditions and to slurry designs used in other similar wells. The challenge is to avoid the open hole closure by the taquihydryte before the next phase is drilled and cased. In order to do so, it was programmed to use a heavy spacer to maintain the wells stability for at least 30 days, due to hydrostatic pressure. This spacer and the heavy salt slurry (18,5 lb/gal) were used for the first time in Brazil. To cement the production casings, similar formulations were used, although with 15,8 lb/gal density slurries and a minimum of 10% bwow salt (NaCl). On the surface cementing operations, light slurries with sea water, salt, and, silicate and aluminate based additives, were designed and used, followed by the 15,8 lb/gal with 18% bwow salt slurry. Information about the different slurries are presented. (author)

    Firefighters are exposed to a wide range of risks, among them, biological risk. The objective was to analyze working conditions of firefighters in the city of Campo Grande, MS, Brazil, focusing on risk conditions of exposure to biological material. Three hundred and seven (307) firefighters were interviewed for data collection and observed for ergonomic job analysis (AET). 63.5% of the firefighters suffered some kind of job related accident with blood or body fluids. Statistically significant association was found between having suffered accidents at work and incomplete use of personal protective equipment (PPE). About AET regarding the biological risks, 57.1% of all patients had blood or secretions, which corresponds in average to 16.0% of the total work time, based on a working day of 24 h. Besides biological risks, other stressing factors were identified: emergency and complexity of decision, high responsibility regarding patients and environment, and conflicts. Health promotion and accident prevention actions must be emphasized as measures to minimize these risks.

    Full Text Available Sediment samples from the Imbé, the Urubu and the Ururaí rivers and from Lake de Cima were studied. These sites are located in the county of Campos dos Goytacazes, Rio de Janeiro, Brazil. Aliphatic and aromatic fractions were analyzed by GC-FID and GC-MS in order to gather information on the degree of contamination by anthropogenic activities and other biogenic contributions. Concentrations of total aliphatic and aromatic hydrocarbons were 1.2, 2.8, 5.8 and 4.3 mug g-1 and 74, 30, 722 and 340 ng g-1 in the Imbé, Ururaí, Urubu rivers and Lake de Cima, respectively. The C20 highly branched isoprenoid alkane was identified in the Urubu sediment. There were no hopanes or steranes in any sample. Anthropogenic aromatic compounds, detected at trace levels, were observed only in the Imbé and in Lake de Cima (227 ng g-1. The fluoranthene/pyrene rate for Lake de Cima was 4.2, suggesting a combustion origin for the PAH. This data is consistent with the frequently sugar cane burning practice that occurs in this region. A greater input from higher plants was observed in the Urubu, Imbé and Lake de Cima sediments; on the other hand, the aquatic input predominates for Ururaí. In summary, Lake de Cima sediment is considered very slightly polluted, while the others are unpolluted.

    Full Text Available Uno de los problemas básicos de nuestro tiempo constituye la incomunicación social, por cuya razón CIESPAL realizó un conjunto de investigaciones básicas sobre comunicación en grupos marginados de áreas rurales del Ecuador y sobre "incomunicación" de esos mismos grupos con otros estratos o sectores sociales. Las investigaciones fueron complejas y de carácter interdisciplinario, ya que, para descubrir los mecanismos, procesos y efectos de la comunicación en esos campos, fue menester estudiar diversos aspectos: sociológicos, antropológicos, económicos, movilidad física y social y específicamente los relacionados con la comunicación en sus diversas formas: interpersonal, por exposición a los medios de comunicación colectiva y todo el sistema de traslaciones culturales que opera bajo cualquier modalidad de comunicación humana.

    Full Text Available RESUMO Este trabalho relata uma pesquisa de campo qualitativa que teve como objetivo estudar os vínculos afetivos no contexto de acolhimento institucional. Participaram do estudo quatro mães sociais, 31 crianças e cinco adolescentes. Foi realizada, com cada mãe social, uma entrevista semiestruturada e, em cada casa lar, três observações participantes. Os dados foram analisados mediante a técnica da Análise Temática, sendo especificadas duas categorias de análise. O trabalho evidenciou aspectos que podem dificultar o estabelecimento de vínculos afetivos: escassez de atividades que estimulem a interação, excesso de atividades domésticas e a falta de preparação das mães sociais para o exercício da função. No entanto, apesar das dificuldades encontradas, o estudo mostrou que é possível a formação de vínculos afetivos nesse contexto.

    Full Text Available The following article discusses the existence of an Colombian documentary film which works from the aesthetics of dissent and proposes to art as a political space, understood the concept of politician as the intersection between power and resistance where the debate it generates, as proposed by Jacques Rancière. They are films that seek to create a disarticulation in the consensual order of historical narration that prevails in Colombia and are characterized by developed in marginality and pose creation from the compression of the consensus agreements to have arguments for discussion. Colombia since the mid of the last century is mired in violence coming from different fronts, media have been commissioned to disseminate and publicly support power agreements. In this environment, this research seeks to respond: how is accomplished dislocate the public consensus and build a dissenting memory that survives to the saturation of the discourses circulating around violence in Colombia? This paper will discuss the work of the Colombian director Óscar Campo as representative of this proposal. His work comprises a range of narratives which, although they are different each other, they maintain some cohesion and progression in a story that manages to create unconventional political – aesthetic criteria of Colombian violence.

  5. "Eu quero uma casa no campo": a busca do verde em Belo Horizonte, 1966-1976

    Directory of Open Access Journals (Sweden)

    Regina Horta Duarte

    Full Text Available A expansão de condomínios horizontais esteve diretamente relacionada às condições históricas que acarretaram a deterioração e o abandono do centro urbano de Belo Horizonte, entre meados das décadas de 1960 e 1970. Nesse contexto, alguns tiveram o privilégio de escolher o sonho da casa no campo, atraídos por promessas de uma vida renovada, mergulhados nos paradoxos do desenvolvimento e dos dramas sociais, políticos e ambientais em curso no Brasil durante a ditadura civil-militar. Cientistas e técnicos realizavam as primeiras avaliações dos dilemas da poluição ambiental urbana. Entretanto, temas ambientais se configuravam como assunto extemporâneo e distante da política, subestimados por setores brasileiros de direita e esquerda. A perda de qualidade de vida em Belo Horizonte recebeu soluções individuais, por vezes com aspectos comunitários. O caráter simultâneo desses processos na capital mineira esclarece casos históricos similares em outras grandes metrópoles brasileiras e latino-americanas.

    2017-02-01

    Full Text Available O artigo traz uma discussão sobre o estudo da visualidade urbana segundo uma abordagem interdisciplinar. Segundo a proposta aqui indicada, parece útil entender os fenômenos urbanos sob um outro olhar. Torna-se muito conveniente considerar a interação entre tecnologia, arte e ciência na constituição dos estudos sobre o ambiente urbano e sobre a produção da imagen. Tendo em mente tal concepção, pode-se partir de uma referência mais concreta para estudar a cidade e a visualidade, como um campo de múltiplas produções em abordagem interdisciplinar. Para isso foi selecionada a produção do grafite nas metrópoles brasileiras. Nos muros de Salvador há uma série de grafites que merecem a reflexão e um acolhimento crítico por tratarem exatamente de problematizar o olho e o olhar no ambiente da cidade.

    Among the compounds stored by plants, several functions are assigned to fructans, such as source of energy and protection against drought and extreme temperatures. In the present study we analyzed the anatomy and distribution of fructans in vegetative organs of Dimerostemma vestitum (Asteraceae), an endemic species from the Brazilian campos rupestres. D. vestitumhas amphistomatic and pubescent leaves, with both glandular and non-glandular trichomes. In the basal aerial stem the medulla has two types of parenchyma, which differ from the apical portion. The xylopodium has mixed anatomical origin. Interestingly, although inulin-type fructans with high degree of polymerization were found in all analyzed organs except the leaves, the highest amount and maximum degree of polymerization were detected in the xylopodium. Inulin sphero-crystals were visualized under polarized light in the medulla and in the vascular tissues mainly in the central region of the xylopodium, which has abundant xylem parenchyma. Secretory structures accumulating several compounds but not inulin were identified within all the vegetative organs. The presence of these compounds, in addition to inulin, might be related to the strategies of plants to survive adverse conditions in a semi-arid region, affected seasonally by water restriction and frequently by fire.

    Herein, we report tick species found on wild and domestic animals and in the environment during a one-year sampling period at the Brazilian Farming Research Company beef cattle unit (Embrapa Beef Cattle), which is located within the urban area of Campo Grande, Mato Grosso do Sul, Brazil. From 55 wild hosts including six different species (Nasua nasua, Cebus spp., Cerdocyon thous, Myrmecophaga tridactyla, Tamandua tetradactyla and Dasyprocta aguti), 323 ticks were collected. Amblyomma ovale ticks were found solely on coatis, and Amblyomma nodosum was identified solely on anteaters. No ticks were found on capuchin monkeys. However, Amblyomma cajennense was found on all parasitized host species with the exception of capuchin monkeys. Giant anteaters displayed the highest infestation abundance, with a mean of 53 ticks∕animal. Environmental sampling yielded 166 adult A. cajennense ticks. The tick species found on domestic animals (Rhipicephalus (Boophilus) microplus, R. sanguineus, Dermacentor nitens and A. cajennense) were those typically found on these hosts in Brazil. The most prevalent tick species, A. cajennense, was found on both wild and domestic animals and was also prevalent in the environment. Thus, this tick species is the primary vector that allows pathogens to bridge wild and domestic animals in the Cerrado.

    Full Text Available Diazepam suppositories are widely used by children and elderly, and require close attention to quality control because it is a controlled prescription drug. The objective of the study was to analyze diazepam suppositories manipulated in Campos dos Goytacazes, RJ, to verify if they are within the required quality standards, and offer safety and efficiency to patients. We analyzed samples of 5mg diazepam suppositories acquired in five randomly selected pharmacies, identified as Pharmacy A, Pharmacy B, Pharmacy C, Pharmacy D, and Pharmacy E. We ran tests on average weight, organoleptic control, hardness, melting point, and dissolution. Data was analyzed and compared with the requirements of the Brazilian Pharmacopoeia. This analysis was made over a table in Excel. We conclude that only C Pharmacy was approved in all tests, and this is the only laboratory that has analyzed the quality of the product warranty. Laboratories A, B, D and E have been approved in some tests, and failed one or more tests. To ensure quality control, suppositories needed to pass in all tests, which was not the case of these labs. Therefore, we recommended the following procedures to the investigated laboratories: changes in packaging, greater precision in handling, quality control prior to dispensing the product, and efficient pharmaceutical care service.

    Full Text Available This article analyses the relationship among entrepreneurship, innovation and growth path regarding the technological cluster in São Jose dos Campos, state of São Paulo. This is an exploratory and descriptive study, supported by documental research and questionnaires applied in a non-probabilistic sample. The results show a relevant social reorganization since CTA/ITA were implemented, in the early Fifties’, which coincides with the arrival of international companies, attracted by the Geographic aspects, high qualified manpower availability and tax benefits. Since then, the municipality has experienced an intense migratory flow of professionals, professors, civil and military students. CTA and ITA generate a considerable level of technological knowledge spillover. Due to it, a number of new companies have started-up operations locally in fields such as Aeronautics, Airspace, Automobile and Petrochemical, which promoted a remarkable social and economic development. Nevertheless, the small and medium technology-based enterprises seem to show high dependence of the core companies in the region that leads to initial stages of internationalization.

    Cambessedesia wurdackii Martins (Myrtales: Melastomataceae) is presumably endemic to the Chapada Diamantina, Bahia State, Brazil. A majority of the species of this family are pollinated by diurnal bees that buzz the floral anthers to collect pollen. The present work examined the interactions between C. wurdackii and visiting bees, focusing on temporal, morphological, and behavioral features, especially in regards to the crepuscular bees Megalopta sodalis (Vachal) (Hymenoptera: Halictidae) and Ptiloglossa off. dubia Moure (Hymenoptera: Colletidae). The study was undertaken in an area of campo rupestre montane savanna vegetation located in the Chapada Diamantina Mountains of Bahia State, Brazil, between August/2007 and July/2008. Flowering in C. wurdackii occurred from April through July, with a peak in May. A total of 592 visits by diurnal and crepuscular bees to the flowers of C. wurdackii were recorded, with a majority of the visits made by M. sodalis and P. dubia (92%) near sunrise and sunset. The anthers of C. wurdackii are arranged in two tiers, which favors cross pollination. The morphological, temporal and behavioral characteristics of M. sodalis and P. dubia indicated that they were potential pollinators of C. wurdackii, in spite of the fact that the colorful and showy flowers of this species are more typical of a diurnal melittophilous pollination syndrome.

    2014-09-01

    Full Text Available Seguindo o modelo dos países ocidentais, na literatura brasileira é significativa a participação de jornalistas na produção literária de seu tempo. Autores clássicos da literatura ocidental, como Honoré de Balzac, Ernest Hemingway, Truman Capote e Euclides da Cunha são apenas alguns exemplos dos mais conhecidos nesse sentido. Partindo do conceito de tribo jornalística, apresentado por Traquina (2005, pode-se apresentar uma tribo especificamente literária que está inserida no campo jornalístico brasileiro, formada por escritores que atuam ou atuaram nas redações e nas páginas dos livros, tanto no sentido de produção de jornalismo literário, como Caco Barcellos, quanto no de produção de contos e romances, como foi o caso de Erico Verissimo, por exemplo. Considerando isso, para a presente análise do tema, optou-se por restringir o estudo dessa tribo exclusivamente no cenário brasileiro. Para tanto, metodologicamente esse estudo se caracteriza como sendo de tipo exploratório com base na pesquisa bibliográfica.

    Full Text Available The objective of this study was to evaluate the tourism potential of birds found in three public green areas (a park, a square and a pond, in the city of Campo Grande. The qualitative survey of avifauna totaled 55 observation hours, by the method of direct observation by points. The species were recorded and the frequency of occurrence (FO of each species by analyzed area was calculated. We recorded 107 species, totaling 12% of the Cerrado biome and blue-and-gold macaws were the species with absolute frequency of occurrence in the three areas. Each of the areas presented exclusive species and the park, the largest number of recorded species, standing out as an appropriate place to hold the birdwatch. However, the tourism potential for observing these birds should be strengthened by other actions such as check for complementarity between supply and demand, planning and building elements themselves to the observation activities, organize and present the practical arrangements for the birds observation in accordance with the supply constraints and the level of involvement and expertise of birdwatchers. Local people should be mobilized and motivated to know about the birds that are part of the landscape; the private sector can use a formatted tourism product and create new products or needs, such as crafts or printed guides; and the participation of the government is essential in promoting the 'birdwatching urban script ' product, as in the maintenance of urban nature reserves.

    The Sansão-do-campo, also known as sabiá, is a plant whose wood has multiple uses, besides its ornamental value. It is used in forestry, for hedges and as forage. The flowers are visited by bees and tree stalk bark is used to treat lung diseases. The Sansão-do-campo seeds have shown germination problems due to tegument impermeability. To study this problem an experiment was carried out with seeds collected in August 2000 in Jussara, Goiás State. Pure seed samples were immersed in sulfuric acid (H2SO4 P. A. for 0, 5, 10, 15, and 20 minutes and then washed in running water for 10 minutes to remove acid residues. Seeds were dried and then submitted to the standard germination test. Statistical analysis showed that H2SO4 immersion for 10 to 15 minutes resulted in the highest germination rate (98%.

Exposed the geological constitution of the landscape integrated by devonian beds in the Campos Gerais serie and the glacial deposits of the Itararé formation, the results of petrographic-sediment researches and the coefficients of selection of various sediments are given. A rapid exposition of the phytogeographic and climate conditions - according to Koeppen = 7 Cfb - is followed by the presentation of the results of the physical and chemical researches made in the soils of eight profiles, illustrated with the corresponding charts and by volumetric-chemical diagrams. The authors came to the conclusion that the part of Campos Gerais here taken into consideration is characterized by poor and washed soils, motivated by geological and climatic conditions. These soils lack specially in phosphorus, calcium, nitrogen and potassium. Two of the profiles constituted exception as they correspond to the area covered by a forest island, therefore, showing its soils in a little better condition.

Este estudo objetivou avaliar os óxidos de ferro pedogênicos em um Latossolo sob campo e floresta nativa e relacionar os mesmos com os teores de carbono orgânico e a área superficial específica do solo. Os teores de carbono orgânico são maiores no solo sob floresta e, possivelmente, influenciaram processos dissolutivos de óxidos de ferro cristalinos e a neoformação de tipos metaestáveis de baixa cristalinidade. O incremento de C orgânico no solo sob floresta elevou expressivamente a área superficial específica do solo, mascarando o efeito geralmente positivo dos óxidos de Fe sobre essa característica física.

    José Antonio Campos-Ortega (1940-2004), a Spanish scientist who became a leading figure in the developmental genetics of the nervous system, spent most of his scientific life in Germany. Nevertheless, he remained deeply rooted in his native country. His thinking, his ambition and his work were driven by scientific, philosophical and historical questions. He started as a neuroanatomist, working first in Valencia, then in Gottingen, Tubingen and Freiburg. He used primates, reptiles, then the house fly and finally Drosophila to address the question How is the brain or the eye structured in order to function?. While in Freiburg, the problem shifted to How does the nervous system come into being, into form? Campos-Ortega tried to understand early neurogenesis in Drosophila through formal genetics, by identifying relevant genes and studying their genetic interactions. Since he was convinced that not only a single experimental approach could solve a problem as complex as the development of the nervous system, he also included the molecular biological approach when he moved to Cologne, while maintaining a strong focus on anatomy, embryology and genetics. There, he also started to work on the neurogenesis of the zebrafish, using similar concepts and approaches. Throughout his scientific career, he thought, wrote and taught about the evolution of methods and ideas in his field of research. At Campos-Ortegas early death, an unfinished book manuscript was left, entitled Developmental Genetics. The Path to the Biological Synthesis. Some parts of his introductory overview are included here.

    Apresentaremos os resultados de uma investigação polarimétrica na região de formação estelar junto à nuvem escura Lupus 1. Esse estudo baseia-se em polarimétria CCD obtida na banda R, e cobre Lupus 1, bem como a área vizinha a essa nuvem contendo a cavidade em 100 mm IRAS. Os dados observacionais foram coletados com o telescópio IAG de 60 cm do Observatório do Pico dos Dias (LNA/MCT - Brasópolis - MG). Nossa primeira análise mostra que uma variação da orientação do campo magnético através da região pode produzir padrões complexos de polarização cuja geometria do campo não pode ser facilmente determinada. Os padrões de polarização são inconsistentes com um campo magnético estritamente uniforme e unidimensional em larga escala. Comparação com a emissão em 100 mm mostra que localmente os vetores de polarização exibem um forte alinhamento com a orientação dos padrões observados em infravermelho.

    Full Text Available Este artigo busca compreender o surgimento do modelo nacional de institucionalização do campo arquivístico, formulado pela Associação dos Arquivistas Brasileiros durante a década de 1970, configurando um quadro corporativista evidenciado pelas conquistas desse associativismo na relação com o Estado brasileiro. Objetiva especificamente analisar o discurso do associativismo arquivístico sobre a institucionalização das esferas acadêmico-universitária do saber arquivístico e sua reserva de mercado profissional. A abordagem metodológica foi utilizar os editoriais da revista Arquivo & Administração, entre 1971 e 1978, selecionando enunciações sobre o processo de institucionalização do campo arquivístico. As análises apontam para uma década de incessantes esforços para eliminar, do campo profissional, o livre exercício da ocupação, para fortalecer o âmbito da formação. Associado à seleção dos enunciados significativos, depreendeu-se a rede de pessoas interessadas nos arquivos, em condições históricas de restrição política, que construiu articulações frente ao Estado, diante de pontos de vista contrários, se tornando um movimento associativo realizador em suas demandas.

Paralelamente à modernização que alcança o campo da investigação, a pesquisa também traz inovações metodológicas, ao testar e ampliar o uso da fotografia digital como um recurso para a fotoetnografia, discutir os seus recursos e limites e também os recursos da Internet, uma vez que o caderno de campo é publicado sistematicamente no site www.ufrgs.br/fotoetnografia, no ar desde o mês de julho de 2003.This research presents an ethnographic and photoethnographic experiment with digital equipment. The research aims to register the transformations through which a rural fishing community is going through, in Viam��o, in the vicinities of Porto Alegre, RS, Brazil. The Vila, called Vila de Itapuã, is surrounded by the Guaíba river on one side and by the Patos lagoon on the other; in the year 2002 the paths to the Vila were asphalted and a wild life reserve park was opened, inviting visitors to end this Vila's isolation. The former isolation of the place was a fundamental reason for the establishment, in the 1940's, of the Colony Hospital, a prison-leprosarium. The present research

    Full Text Available O ambiente rural caracteriza-se por uma região não urbanizada. É o campo em contraponto com a cidade. A zona rural sempre foi classificada como um ambiente repressor e conservador, já a cidade tem como características o anonimato e a liberdade. Na lógica que a heterossexualidade é normatizada em todos os ambientes, uma comunidade campal tem enraizada questões como o machismo e a heteronormatividade de forma mais intensa que o ambiente urbano, por conta de questões geográficas e de valores socioculturais. Contudo, existe uma alegação que em comunidades rurais há uma consumação de práticas sexuais entre adolescentes homens, ou seja, uma prática sexual gay durante a puberdade masculina. A pesquisa em tela busca comprovar a existência destas práticas “homossexuais”, bem como interpretar a dinâmica que as envolvem a fim de compreender como se performatiza a identidade social destes moços. Tendo por base a etnografia, foi realizada uma pesquisa de campo, nos moldes tradicionais da observação participante de cunho antropológico, durante três meses de intenso convívio social na comunidade camponesa Olhos Cristais (nome fictício do município de Baraúna/RN, em que se observou toda a conjuntura expressa através do cotidiano por diversos momentos e espaços de sociabilidade. Também foram realizadas conversas individuais com quatro rapazes. Os rapazes tinham de 19 a 23 anos de idade, e através da história oral fizeram todo um resgate do aspecto estudado, no que diz respeito à vivencia particular de cada um. De fato, as práticas sexuais e afetivas entre rapazes da zona rural existem e não estão concentradas apenas na adolescência, pois se expressam também até a fase adulta da vida, como foi perceptível. Pensar estas práticas é compreender um mundo de dupla face, onde o âmbito particular e o público assumem formas muitas vezes contrastantes, demonstrando um poder influente e coercitivo da sociedade no processo

    The Serra do Meio granite outcrops near the town of Campo Alegre de Lourdes, north-northeast of Bahia State. The granite is intrusive into micachists, which are correlatives of the Salgueiro-Cachoeirinha Group (Early Proterozoic), during early to the syn-tectonic shear phase. The geological setting also comprises a phosphatic rock-bearing carbonatitic complex and gabbroid complexes with one of the main world resources of Fe-Ti-V. The granite mineralogical composition grades from Aegerine-augite alkali-feldspar granite/syenites to Leuco alcali-feldspar granite. The geochemical analysis shows SiO 2 -enrichment (67 to 76%), in alkalis (Na 2 +K 2 O, 7,5 to 12,5%), Nb (up to 680ppm), Zr (up to 2,390ppm), Y (up to 250ppm) e REE (up to 796ppm). The geochemical behaviour is peculiar to alkaline series, denoting a silica-oversaturated, potassium-rich, magma. The chondrite-normalized REE patterns display a first group with smooth slopes from the La to Lu, and a second one with negative slopes. Negative Eu anomalies are displayed in all the patterns. The first group is HREE-enriched, with low fractionation ratios. Samples with milonytic fabrics and higher fractionation ratios are related to the second group, suggesting the interaction of metassomatic fluids and the alkaline magma. Discriminant diagrams for Nb, Y and Rb, coupled with geophysical data, point to an intrusive granite in an extensional within a plate tectonic setting of attenuated continental crust. (author) [pt

    The Campo de Calatrava Volcanic Field (CCVF) or Spanish Central Volcanic Zone is located in central continental Spain (Ciudad Real province) and covers about 5000 km2. It includes around 240 eruptive centers, mainly monogenetic basaltic cones but also explosive maar structures. According to K-Ar geochronology, its main activity phase occurred during Pliocene and Pleistocene epochs (between 5 and 1.7 Ma) and involved alkaline to ultraalkaline magmas, although an older ultrapotassic phase is dated around 8.7-6.4 Ma. However, some recent works have proposed Holocene ages for some of the volcanic products, opening the possibility of considering the CCVF "active" according to international standards. Responding to this situation, the Instituto Geográfico Nacional (IGN) has initiated geochemical and geophysical monitoring activities in the CCVF. Here, we describe these ongoing efforts and we report results about groundwater geochemistry at several natural highly-gaseous springs in the area (hervideros), as well as soil temperature, CO2 diffuse flux from the soil and electrical self-potential data mapped on a small degassing structure called La Sima. In order to analyze microseismicity or any seismic anomaly in the CCVF, a seismic station has also been installed close to this degassing structure. Physicochemical parameters (temperature, pH, Eh and electric conductivity) were measured in situ in four springs and samples were taken in order to analyze major ions and trace elements. Total composition of dissolved gases and helium isotopic ratios were also determined. To complete soil temperature, self-potential and gas prospections performed in La Sima, soil gases were sampled at the bottom of the structure at a depth of 20 cm. Analysis of the total gas composition found 957400 ppm of CO2. Low values of O2 and N2 were also detected (5600 and 24800 ppm respectively).

Entretanto, mesmo sendo tão representativas essas empresas enfrentam dificuldades durante a sucessão, que devido à falta de planejamento sucessório e da preparação dos futuros herdeiros muitas delas não chegam a segunda e a terceira geração. Com este trabalho foi possível analisarmos o processo sucessório e a importância do planejamento e da profissionalização dos sucessores. Os dados foram coletados por meio de entrevistas com base em um roteiro de perguntas semi estruturadas realizadas com os sucessores de duas pequenas empresas familiares em Campos dos Goytacazes que já passaram pelo processo sucessório. Apesar de não ter ocorrido um planejamento sucessório o fato dos sucedidos levarem seus herdeiros para a empresa quando crianças e os familiarizando ao negócio contribuiu para que a transição ocorresse sem muitos impactos dando continuidade a um empreendimento próspero.

  9. Soil attributes drive nest-site selection by the campo miner Geositta poeciloptera

    Substrate type is a key-factor in nest-site selection and nest architecture of burrowing birds. However, little is known about which factors drive nest-site selection for these species, especially in the tropics. We studied the influence of soil attributes on nest-site selection by the campo miner Geositta poeciloptera, an open grassland bird that builds its nests within soil cavities. For all nests found, we measured the depth of the nest cavity and the resistance of the soil to penetration, and identified the soil horizon in which the nest was located. In soil banks with nests, we collected soil samples for granulometric analysis around each nest cavity, while in soil banks without nests we collected these samples at random points. From 43 nests found, 86% were located in the deeper soil horizons (C-horizon), and only 14% in the shallower horizons (B-horizon). Granulometric analysis showed that the C-horizons possessed a high similar granulometric composition, with high silt and low clay contents. These characteristics are associated with a low degree of structural development of the soil, which makes it easier to excavate. Contrarily, soil resistance to penetration does not seem to be an important criterion for nest site selection, although nests in more resistant the soils tend to have shallower nest cavities. Among the soil banks analyzed, 40% of those without cavities possessed a larger proportion of B-horizon relative to the C-horizon, and their texture was more clayey. On the other hand, almost all soil banks containing nest cavities had a larger C-horizon and a silty texture, indicating that soil attributes drive nest-site selection by G. poeciloptera. Thus, we conclude that the patchy distribution of G. poeciloptera can attributed to the infrequent natural exposure of the C-horizon in the tropical region, where well developed, deep and permeable soils are more common.

The methodology used to carry out the EIS was very particular and easy to be extrapolated to similar cases, but not to be generalized. It was based in comparing the future project. with the actual intensive irrigation farming of the land, and with the future urban consequences due lo its position next to Toledo city. The comparison between the different environmental impacts of this project and a the actual use of the land, suffering a very intensive irrigation farming, and b the future without the project, was favourable to the golf course, because it was concerned as less aggressive. An appropriate water managing will allow reducing the consumption from the actual 99 l/s authorised for agricultural use, until 54 l/s required for the golf course, improving the environment of this section of the Tajo river: The turf management will be less harmful than the irrigation farming, this one being held nowadays with a high pesticide consumption. Later on, environmental management practice will allow to reduce costs and will help to increase golf-players environmental consciousness. This new golf course will provide the integration o/ this section of Tajo River in the future urban development of Toledo city, creating a green island in its west side, profitable for all city dwellers. This change will be a great improvement, not only for Toledo’s environment, but also for the development of different economical sectors. due to the golf course implantation.Se expone el estudio realizado sobre la incidencia ambiental de un futuro campo de golf en Toledo

En campo se cuantificó altura total, diámetro, y absorción de nutrimentos en el follaje. Los resultados mostraron que en vivero los mayores incrementos promedio, en los tratamientos inoculados, los registró el ronrón (Astronium graveolens, la teca (Tectona grandis y el amarillón (Terminalia amazonia, con 48,9, 35,2 y 30,6%, respectivamente; mientras que en melina (Gmelina arborea el incremento fue de 16,9%. El mayor incremento se registró en el peso seco del follaje y en el radicular con 30,8 y 63%, respectivamente. En la absorción de nutrimentos el ronrón mostró diferencias en Mg, Cu, Zn, Mn y Fe, tanto en el follaje como en el sistema radicular; sin embargo, melina fue la especie que registró las concentraciones de nutrimentos superiores, aunque no significativas; las demás especies no registraron diferencias significativas. En el campo, en las plantas inoculadas, solamente melina reflejó diferencias significativas en diámetro y altura total, con un incremento de 37,9 y 31,7%, respectivamente. La absorción de nutrimentos de melina, amarillón y ronrón fue en promedio 32,2, 19,8 y 6,6%, respectivamente, con una mayor absorción en Ca, Mn, K y Fe.

    Full Text Available In the framework of the artistic postmodernism, and with reference to the movement of the trans-avant-garde in Italy, whose ideology we find clear similarities, the theatre of Jesús Campos, located by critics within the movement called «Nuevo Teatro Español», due to their expressive boldness and its commitment to anti-Franco, however differs from most of the authors. Thus, unlike these playwrights, Campos does not reject frontally the realism of 50 and 60, or the tradition of comedy and the sainete frequented by conservative authors of the time. On the contrary, since its inception in the early 1970s, Campos uses both forms as expressive resources, from the conviction that the avant-gardes are just one more link in tradition. The analysis of these aspects calls into question the periodization that is being commonly used in the most recent Spanish theatre historiography.En el marco de la posmodernidad artística, y tomando como referencia el movimiento de la transvanguardia en Italia, con cuyos presupuestos encontramos claras similitudes, el teatro de Jesús Campos, situado por la crítica dentro del movimiento llamado «Nuevo Teatro Español», debido a su audacia expresiva y a su compromiso antifranquista, se distingue no obstante de la mayoría de los autores de este grupo en que, lejos de rechazar frontalmente el realismo de los años 50 y 60, ni la tradición de la comedia y el sainete frecuentadas por los autores conservadores del momento, Campos, ya desde sus inicios a comienzos de los 70, emplea unas y otras formas como recursos expresivos, desde el convencimiento de que las vanguardias no son sino un eslabón más de la tradición. El análisis de estos aspectos pone en cuestión la periodización que viene usando de forma habitual la historiografía del teatro español más reciente.

    In 1989, a commitment was made to begin development of a framework for an integrated regional impact assessment of global warming scenarios in the Mackenzie Basin, the most populated region of Canada's north. The project, called Mackenzie Basin Impact Study (MBIS), is led by a multidisciplinary working group from government and non-governmental organizations with interests in the Basin. Objectives of MBIS include defining the direction and magnitude of regional-scale impacts of global warming scenarios on the physical, biological, and human systems of the Basin. MBIS will also identify regional sensitivities to climate, inter-system linkages, uncertainties, policy implications, and research needs. MBIS research activities as of March 1992 are outlined and policy concerns related to global warming are listed. Two new methodologies are being developed by MBIS to address particular economic and policy concerns: a socio-economic resource accounting framework and an integrated land assessment framework. Throughout MBIS, opportunities will be presented for western science and traditional native knowledge to be integrated

    Full Text Available A pesquisa busca analisar as atividades de campo na disciplina de Geologia Introdutória nos cursos de Geografia no Estado do Paraná. Os dados foram coletados por meio de entrevistas com os professores responsáveis pela disciplina, nas instituições de ensino que mantêm o curso de Geografia no Estado. A análise dos resultados possibilitou caracterizar a prática dos professores nas atividades de campo, desde a preparação até a execução, além de constatar as diferentes visões de ensino dos diferentes profissionais que atuam nesta disciplina. Os depoimentos dos professores foram examinados a partir de duas categorias de análise: as características das saídas de campo e as concepções sobre a disciplina de Geologia Introdutória. A análise demonstrou que não há diferenças significativas entre os professores no que diz respeito aos trabalhos realizados em campo, independentemente da formação, titulação e instituição onde atuam. As diversas alternativas de trabalhos de campo ainda estão distantes da prática da maioria dos professores, que optam por atividades voltadas ao reconhecimento no campo de conteúdos desenvolvidos em sala de aula. Entretanto, revelaram-se duas concepções distintas quanto ao papel da disciplina no curso e os conteúdos que deve abranger: a visão do professor geólogo e a visão do professor geógrafo. Em que pese tais diferenças, as concepções de ambos os profissionais não são, de modo geral, compatíveis com as características e conteúdos dos trabalhos de campo que promovem.

    Operation of L Reactor will necessitate annual cleaning of the L Area 186 basins. Alternatives are presented for sediment discharge due to 186-basin cleaning activities as a basis for choosing the optimal cleaning method. Current cleaning activities (i.e. removal of accumulated sediments) for the P, C and K-Area 186 basins result in suspended solids concentrations in the effluent waters above the NPDES limits, requiring an exemption from the NPDES permit for these short-term releases. The objective of mitigating the 186-basin cleaning activities is to decrease the suspended solids concentrations to within permit limits while continuing satisfactory operation of the basins

    Full Text Available Una mañana tranquila auguraba un perfecto y usual día de campo. A las 12,50 horas nos encontrábamos a la vera de la ruta, según se había programado en la secuencia de tareas, disfrutando del típico día patagónico, con fuerte viento. El viento no cesa y su intensidad parece aumentar; se hace difícil la ejecusión de cualquier tarea, pero es este mismo viento el que me invita a apreciar un panorama incomparable frente a mis ojos. Encontrándome apoyado en un poste de alambrado y mirando hacia el noroeste, puedo apreciar una gigantesca masa nubosa que abarca casi la totalidad del horizonte. Su color dista mucho de ser el característico de una nube y de hecho su albedo es mucho menor. Obviamente no estoy observando ninguna forma conocida de condensación de vapor de agua, sino una gigantesca nube de polvo cuyas dimensiones sólo causan asombro. Pero ¿ porque un día como hoy no la observo rodeándome, cubriéndome y haciendo mi estadía imposible en este poste? La respuesta es más sencilla de lo que cualquier lector pueda imaginar y la explicación es la siguiente: sucede que estoy mirando en dirección a la cola del embalse del Lago Ezequiel Ramos Mejía cuyo nivel se encuentra muy disminuido. Ahora bien ¿qué significa esto? Esto significa un perfecto ejemplo de cómo el viento favorece los procesos geomorfológicos. El agua que ocupaba la zona, ahora desierta, impidió el crecimiento de vegetales que actúan como sostén del suelo, actuando ella misma como agente retensivo al otorgar peso a las partículas. Ahora que ya no está, que bajo considerablemente su nivel, dejó el suelo a la intemperie. Una intemperie que es mayor aún si considero la presencia del desierto patagónico a su alrededor. Los fuertes vientos levantan a las indefensas partículas y la transportan en suspensión. Como la cantidad es muy grande, forman verdaderas nubes y aún desconociendo sus principales efectos, me atrevo a decir: “ahí va nuestro suelo”. Y

    Full Text Available Ao definir o espaço de constituição do capitalismo e da modernidade, Fernand Braudel, em seu clássico Civilização Material, Economia e Capitalismo, não hesita em afirmar a cidade como o lócus de construção histórica desta modernidade. As cidades são, para este autor, como transformadores elétricos: elas aumentam as tensões, precipitam as trocas, removem a vida dos homens. São nascidas da mais revolucionária divisão do trabalho: campo de um lado, atividades urbanas do outro. A cidade é cesura, ruptura, destino do mundo. Ao surgir com a escritura ela abre as portas para a história; quando renasce na Europa no séc. XI a ascensão do continente começa, quando ela floresce na Itália, é o Renascimento. Tão importante quanto seu conceito de longa duração, muitas vezes referenciado entre historiadores e cientistas sociais, Braudel ao dar tamanha importância ao espaço e à cidade também pensou num conceito que desse conta da dinâmica que envolve a cidade e a história, a pouco citada longa dimensão. A vida da cidade está associada a um espaço de longa dimensão, de onde vêm seus homens, onde estão suas relações comerciais, cidades, vilas e mercados que aceitam os seus pesos e medidas ou suas moedas, ou que falam a sua língua dialetal (s.d.: 560-1.

    This work is related to the reliability engineering, specifically, to the analysis of data lifetime and to the failure modeling of Permanent Downhole Gauge monitoring systems (PDG/TPT) in Marlim field, Campos Basin. These systems are composed of pressure and temperature sensors installed in oil wells and connected, by umbilicals, to their production platforms. The raising of the main failure causes in these systems, in 12-year operation, served as the basis to describe their driving parameters, foreseeing their behavior for the following years, considering the reliability theory of systems. It was obtained the pattern of the operations and extracted the wanted information: types and failure modeling, systems survival time and the Mean Time Between Failures (MTBF). This methodology permits the comparison among the components performance from several manufacturers. The results can be used in economical analysis, in oil field management, in maintenance prediction and in reliability studies. The area of failure modeling in association with these systems lifetime is the focus of this study. (author)

    In the next decades, oil exploration by majors and independents will increasingly be in remote, inaccessible areas, or in areas where there has been extensive shallow exploration but deeper exploration potential may remain; areas where the collection of data is expensive, difficult, or even impossible, and where the most efficient use of existing data can drive the economics of the target. The ability to read hydrocarbon chemistry in terms of subsurface migration processes by relating it to the evolution of the basin and fluid migration is perhaps the single technological capability that could most improve our ability to explore effectively because it would allow us to use a vast store of existing or easily collected chemical data to determine the major migration pathways in a basin and to determine if there is deep exploration potential. To this end a the DOE funded a joint effort between California Institute of Technology, Cornell University, and GeoGroup Inc. to assemble a representative set of maturity and maturation kinetic models and develop an advanced basin model able to predict the chemistry of hydrocarbons in a basin from this input data. The four year project is now completed and has produced set of public domain maturity indicator and maturation kinetic data set, an oil chemistry and flash calculation tool operable under Excel, and a user friendly, graphically intuitive basin model that uses this data and flash tool, operates on a PC, and simulates hydrocarbon generation and migration and the chemical changes that can occur during migration (such as phase separation and gas washing). The DOE Advanced Chemistry Basin Model includes a number of new methods that represent advances over current technology. The model is built around the concept of handling arbitrarily detailed chemical composition of fluids in a robust finite-element 2-D grid. There are three themes on which the model focuses: chemical kinetic and equilibrium reaction parameters, chemical

    trabajo de investigación sobre la consolidación y emergencia del campo teatral bogotano.  Aquí se explora particularmente la incidencia del denominado Movimiento Nuevo Teatro, el cual se desarrolló en América Latina desde los años cincuenta hasta los años setenta del siglo pasado. En Colombia, éste va a cobrar singular importancia generando, aun hoy, álgidos debates sobre el verdadero papel de la creación colectiva y la organización en grupos en cuanto a la transformación de la dramaturgia, y la actividad teatral en el país. Tales debates se toman aquí como otro dato más, junto con el discurso de los demás agentes pertenecientes al campo a través de los libros de historia sobre el teatro colombiano y los textos teóricos de varios de sus protagonistas. La información se complementa con la suministrada por revistas especializadas y por las instituciones oficiales encargadas del área de cultura. Al final, una de las conclusiones centrales es que se puede hablar de un campo teatral en Bogotá gracias a la autonomía suficiente que se obtuvo por tres búsquedas puntuales: la adquisición de una sala propia, la formación del público y la creación de una dramaturgia nacional.

    Jorgeane Schaefer-Santos

    Full Text Available Os ecossistemas campestres entremeados aos fragmentos de Floresta com Araucária são comuns na serra catarinense. Existem fortes indicativos de que parte dos campos da região, os não hidromórficos, sobre solos minerais, seja resultante da exploração da floresta ou do impedimento de seu avanço, cuja cobertura, hoje, é inferior a 10%. Porém, os hidromórficos, exclusivamente em Organossolos, ocupando feições específicas na região, dão evidências de serem, embora impactados, naturais. O presente estudo teve como objetivo mapear a localização dos campos hidromórficos, partindo de dados de campo comparados aos mapas de fatores hidrológicos produzidos principalmente a partir do modelo digital de elevação (MDE e rede de drenagem. Os resultados mostram que o comprimento de fluxo superior a 400 m está positivamente correlacionado à profundidade das zonas hidromórficas. Os relevos patamarizados e planos relacionam-se às zonas hidromórficas, porém a escala do estudo não leva à caracterização final das mesmas. Ainda que os resultados sejam em caráter preliminar, nota-se que pesquisas complementares abordando análise espacial do relevo são necessárias.

Campo Grande at first cut and after 21 days of regrowth at different levels of potassium (K2O with and without zinc (Zn. The experiment was conducted using a randomized block design in a 4 x 2 factorial scheme consisting of four repetitions. Four levels of K2O (0, 120, 240 and 360 mg/dm3 with and without Zn (0 and 6 mg/dm3 were used. There was no effect of the interaction between K2O and Zn levels on the structural characteristics of Stylosanthes cv. Campo Grande, and no independent effects of the different levels of K2O and Zn were observed. The mean plant height, total number of leaves and number of live leaves were 21.2 cm, 30.2 and 27.2, respectively. Dry mass production did not differ between K2O and Zn levels, with a mean production of 3.7 g/pot. There was also no effect of the interaction between K2O and Zn levels on dry matter and neutral detergent fiber content, and no independent effects of the different levels of K2O and Zn were observed, with mean values of 29.3% and 46.9% dry matter, respectively. However, an effect of the interaction between K2O and Zn levels was observed for crude protein content, which exhibited a quadratic response. Re2growth increased linearly with increasing K2O levels. Although the highest crude protein content was obtained at zero levels of potassium and zinc, potassium fertilization is advantageous since it increases the regrowth of Stylosanthes cv. Campo Grande in 21 days.

Nossa proposta apresenta cinco dimensões, sistematizadas depois de um exercício conduzido pelo método analítico reflexivo, tomando como material 23 artigos concernentes a distintos aspectos relevantes à análise de redes de saúde. Esse exercício, operacionalizando um processo sucessivo de redução semântica, resultou em um modelo composto pelas seguintes dimensões: Unidades mínimas, compreendendo a caracterização dos pontos fixos a partir dos quais ocorrem as conexões da rede; Conectividade, representando as modalidades e efeitos das relações estabelecidas entre as unidades mínimas; Integração, concernente aos efeitos do conjunto das unidades mínimas e suas relações, identificados como coerência, continuidade e complementaridade de ações na rede; Normatividade, indicando a construção e adesão a diretrizes clínicas e linhas de cuidado singulares, assim como o estabelecimento de critérios de encaminhamento, entrada e saída de cada ponto da rede; e Subjetividade, incluindo protagonismos, sentidos, valores e vínculos afetivos circulantes na rede. Essas dimensões, operando de forma recursiva, podem subsidiar a construção de modelos analítico-conceituais de redes como aporte à superação desse desafio no campo da saúde coletiva.

    Full Text Available Este artículo explora la conformación del campo intelectual en la literatura zapoteca del istmo de Tehuantepec y la literatura maya de la Península de Yucatán. A través del concepto de campo intelectual de Pierre Bordieu (2002 y bajo la premisa de que hay tantos campos literarios como literaturas indígenas, se evidencia que estos espacios de poder simbólico están condicionados por elementos socioculturales y políticos que van desde la alfabetización y uso de la escritura en las lenguas indígenas hasta la función de los intelectuales en las redes locales y nacionales. En la literatura zapoteca se indican las estrategias de la generación de Andrés Henestrosa, la relación entre la COCEI y la Casa de Cultura de Juchitán, y los vínculos que sostienen los intelectuales de la región con otros intelectuales de la esfera nacional. Para la literatura maya yucateca se reflexiona sobre la generación de talleres literarios como el principal motor de la nueva literatura maya, tanto desde las instancias gubernamentales como desde las asociaciones civiles y grupos gestionados por los intelectuales mayas.

  5. K West Basin canister survey

    International Nuclear Information System (INIS)

    Pitner, A.L.

    1998-01-01

    A survey was conducted of the K West Basin to determine the distribution of canister types that contain the irradiated N Reactor fuel. An underwater camera was used to conduct the survey during June 1998, and the results were recorded on videotape. A full row-by-row survey of the entire basin was performed, with the distinction between aluminum and stainless steel Mark 1 canisters made by the presence or absence of steel rings on the canister trunions (aluminum canisters have the steel rings). The results of the survey are presented in tables and figures. Grid maps of the three bays show the canister lid ID number and the canister type in each location that contained fuel. The following abbreviations are used in the grid maps for canister type designation: IA = Mark 1 aluminum, IS = Mark 1 stainless steel, and 2 = Mark 2 stainless steel. An overall summary of the canister distribution survey is presented in Table 1. The total number of canisters found to contain fuel was 3842, with 20% being Mark 1 Al, 25% being Mark 1 SS, and 55% being Mark 2 SS. The aluminum canisters were predominantly located in the East and West bays of the basin

  6. Uranium geochemistry of Orca Basin

    Weber, F.F. Jr.; Sackett, W.M.

    1981-01-01

    Orca Basin, an anoxic, brine-filled depression at a depth of 2200 m in the Northwestern Gulf of Mexico continental slope, has been studied with respect to its uranium geochemistry. Uranium concentration profiles for four cores from within the basin were determined by delayed-neutron counting. Uranium concentrations ranged from 2.1 to 4.1 ppm on a salt-free and carbonate-corrected basis. The highest uranium concentrations were associated with the lowest percentage and delta 13 C organic carbon values. For comparison, cores from the brine-filled Suakin and Atlantis II Deeps, both in the Red Sea, were also analyzed. Uranium concentrations ranged from 1.2 to 2.6 ppm in the Suakin Deep and from 8.0 to 11.0 ppm in the Atlantis II Deep. No significant correlation was found between uranium concentrations and organic carbon concentrations and delta 13 C values for these cores. Although anoxic conditions are necessary for significant uranium uptake by non-carbonate marine sediments, other factors such as dilution by rapidly depositing materials and uranium supply via mixing and diffusion across density gradients may be as important in determining uranium concentrations in hypersaline basin sediments.

No primeiro momento retrata o contexto histórico da Educação do Campo, enfocando os desafios do Movimento Por Uma Educação do Canpo destacando a necessidade de políticas públicas para o contexto amazônico, apontando as demandas e as perspectivas da educação para o meio rural. No segundo momento contextualiza a Pedagogia da Alternância focalizando sua origem, questões conceituais, situando a mesma no Estado do Pará. O movimento por uma educação do campo constituído por movimentos sociais que se organizam a partir do campo e que têm apoio de educadores, intelectuais, universidades públicas e organizações não-governamentais. Este movimento, desde a década de 1990, vem constituindo uma discussão teórica sobre a educação do campo como estratégia contra hegemônica frente às políticas do Estado brasileiro direcionadas às populações do campo. Em nosso país o desenvolvimento da Pedagogia da Alternância ganha materialidade como estratégia de inúmeros movimentos sociais organizadas nos Centros Familiares de Formação em Alternância (CEFFAS. É importante enfatizar que a proposição tem sido utilizada como estratégia para garantir a participação de amplos segmentos da sociedade nas decisões e encaminhamentos, garantindo assim, a educação aos filhos dos sujeitos do campo.

  10. The geologic history of Margaritifer basin, Mars

    Science.gov (United States)

    Salvatore, M. R.; Kraft, M. D.; Edwards, Christopher; Christensen, P.R.

    2016-01-01

    In this study, we investigate the fluvial, sedimentary, and volcanic history of Margaritifer basin and the Uzboi-Ladon-Morava (ULM) outflow channel system. This network of valleys and basins spans more than 8000 km in length, linking the fluvially dissected southern highlands and Argyre Basin with the northern lowlands via Ares Vallis. Compositionally, thermophysically, and morphologically distinct geologic units are identified and are used to place critical relative stratigraphic constraints on the timing of geologic processes in Margaritifer basin. Our analyses show that fluvial activity was separated in time by significant episodes of geologic activity, including the widespread volcanic resurfacing of Margaritifer basin and the formation of chaos terrain. The most recent fluvial activity within Margaritifer basin appears to terminate at a region of chaos terrain, suggesting possible communication between surface and subsurface water reservoirs. We conclude with a discussion of the implications of these observations on our current knowledge of Martian hydrologic evolution in this important region.

    Energy Technology Data Exchange (ETDEWEB)

    1993-10-01

    This study characterizes an extremely large gas resource located in low permeability, overpressured sandstone reservoirs located below 8,000 feet drill depth in the Greater Green River basin, Wyoming. Total in place resource is estimated at 1,968 Tcf. Via application of geologic, engineering and economic criteria, the portion of this resource potentially recoverable as reserves is estimated. Those volumes estimated include probable, possible and potential categories and total 33 Tcf as a mean estimate of recoverable gas for all plays considered in the basin. Five plays (formations) were included in this study and each was separately analyzed in terms of its overpressured, tight gas resource, established productive characteristics and future reserves potential based on a constant $2/Mcf wellhead gas price scenario. A scheme has been developed to break the overall resource estimate down into components that can be considered as differing technical and economic challenges that must be overcome in order to exploit such resources: in other words, to convert those resources to economically recoverable reserves. Total recoverable reserves estimates of 33 Tcf do not include the existing production from overpressured tight reservoirs in the basin. These have estimated ultimate recovery of approximately 1.6 Tcf, or a per well average recovery of 2.3 Bcf. Due to the fact that considerable pay thicknesses can be present, wells can be economic despite limited drainage areas. It is typical for significant bypassed gas to be present at inter-well locations because drainage areas are commonly less than regulatory well spacing requirements.

    Full Text Available En el campo de la educación nos encontramos actualmente con dos importantes requerimientos, sólidamente fundamentados, para introducir la Educación para la Sostenibilidad y la Educación en Derechos Humanos. Se trata, en efecto, de dos áreas educativas prioritarias, a las que UNESCO ha dedicado sendos decenios. Es preciso reconocer, sin embargo, la escasa conexión entre ambas, así como su insuficiente presencia en el sistema educativo, muy particularmente en el nivel universitario. Nuestro propósito en este trabajo es, precisamente, mostrar que, contrariamente a lo que, en general, se ha venido considerando, ambos campos de conocimiento y actividad social están estrechamente vinculados y deben ser abordados conjuntamente para favorecer su mutua potenciación y contribuir a su mayor efectividad. Una Educación para la Sostenibilidad y Derechos Humanos puede convertirse así en un factor clave para la necesaria transición a sociedades sostenibles y un elemento esencial de la nueva Ciencia de la Sostenibilidad.

Therefore, it aims at elucidating the role of Reference Centres for Occupational Health (CEREST, the number of accidents at work and occupational diseases in those ten years, as well as the organization of the Network for Integral Worker Health Care (RENAST, according to the decree of the Ministry of Health. The objective is to verify the efficiency of municipal policies regarding workers’ health through documentary sources, quantitative data, and oral sources. The survey verified the absence of data on strategic actions aimed at the workers’ health, various health care activities, and the political-electoral use of PAST (Workers’ Health Care Program and CEREST. Considering the evolution of the concepts related to health care of those who work, in some sectors, Campos dos Goytacazes has gone through a period that precedes the “industrial medicine” stage - Occupational Medicine. This reality shows bad labor relations, as the municipality is the national champion in work analogous to slave labor. In most cases, the city has to deal with regulatory standards and, in very few moments, puts into practice principles of Workers’ Health.

    Full Text Available O artigo visa problematizar o campo da comunicação na obra de Célestin Freinet, analisando a inter-relação entre educação e comunicação no pensamento educacional do autor. Destaca-se nas obras do educador francês o entendimento da comunicação não somente como mídia - ainda que tenha sido um dos maiores divulgadores de técnicas pedagógicas como o jornal escolar – mas como uma perspectiva teórica e metodológica que edifica seu projeto educativo. O “comunicar-se” alinha-se ao “expressar-se”, “criar, agir e compreender”, “organizar-se” e “avaliar-se”, de modo que a comunicação constitui-se em um eixo e uma finalidade da obra freinetiana. Trata-se de um recorte de tese, com previsão de defesa em março de 2017, que estuda em perspectiva comparada o campo comunicacional como parte da matriz de pensamento na filosofia educacional de John Dewey, Célestin Freinet e Paulo Freire.

    Directory of Open Access Journals (Sweden)

    Joceline Zanchettin

    Full Text Available Resumen Delimitar la intuición clínica de Sigmund Freud en el campo de la psicosis implica analizar las consecuencias de lo no analizable de dicha entidad clínica, tal como lo plantea el propio autor. En este trabajo, se delimita y se discute el lugar de garante de la teoría psicoanalítica, ocupado por el psicótico, y se subraya la suposición de un sujeto en las psicosis, en términos de «no querer saber». La imposibilidad de transferencia vacila ante el análisis que el propio Freud hace del caso Schreber. La Verwerfung se enlaza a un particular modo de retorno, excluyéndose de la relación biunívoca entre mecanismo y estructura clínica. Se manifiesta la intuición clínica de Freud en el punto donde hace del delirio o de las demás producciones en la psicosis una obra que porta la firma de un autor. Dicho recorrido nos permite sostener la importancia y actualidad del texto freudiano al campo de las psicosis.

    Full Text Available Today, there is a considerable increase in the field of cultural referents to be "preserved" and, as a consequence, a proliferation of institutions/mechanisms triggered in face of the threat of disruption/disappearance of these referents, with a growing appreciation of local identities and a questioning of the past on the basis of circumstances and needs of the present. Within this memory boom, we focus the process of assigning meanings to an event narrated by historiography and oral tradition as an important fight in the process of Brazil's independence, viz. the battle of Jenipapo, which occurred in the village of Campo Maior (PI, in the northeastern region of Brazil, on the banks of the River Jenipapo on March 13, 1823. To this end, we approach the polyphonic and multiple work of social memory that takes place in the convergences and divergences between history, myth and tangible signs, as diffuse monuments, places of memory, in the city of Campo Maior (PI.

    Despite the importance of the Missouri River for navigation, recreation, habitat, hydroelectric power, and agriculture, relatively little is known about the basic hydroclimatology of the Missouri River basin (MRB). This is of particular concern given the droughts and floods that have occurred over the past several decades and the potential future exacerbation of these extremes by climate change. Here, observed and modeled hydroclimatic data and estimated natural flow records in the MRB are used to 1) assess the major source regions of MRB flow, 2) describe the climatic controls on streamflow in the upper and lower basins , and 3) investigate trends over the instrumental period. Analyses indicate that 72% of MRB runoff is generated by the headwaters in the upper basin and by the lowest portion of the basin near the mouth. Spring precipitation and temperature and winter precipitation impacted by changes in zonal versus meridional flow from the Pacific Ocean play key roles in surface water supply variability in the upper basin. Lower basin flow is significantly correlated with precipitation in late spring and early summer, indicative of Atlantic-influenced circulation variability affecting the flow of moisture from the Gulf of Mexico. Although increases in precipitation in the lower basin are currently overriding the effects of warming temperatures on total MRB flow, the upper basin’s long-term trend toward decreasing flows, reduction in snow versus rain fraction, and warming spring temperatures suggest that the upper basin may less often provide important flow supplements to the lower basin in the future.

    The New TNX Seepage Basin has been in operation at the Savannah River Plant (SRP) since 1980 and is located in the southeastern section of the TNX facility. The basin receives waste from pilot scale tests conducted at TNX in support of the Defense Waste Processing Facility (DWPF) and the plant Separations area. The basin is scheduled for closure after the TNX Effluent Treatment Plant (ETP) begins operation. The basin will be closed pursuant to all applicable state and federal regulations. A statistical analysis of monitoring data indicates elevated levels of sodium and zinc in the groundwater at this site. Closure options considered for the New TNX Seepage Basin include waste removal and closure, no waste removal and closure, and no action. The two predominant pathways for human exposure to chemical contaminants are through surface, subsurface, and atmospheric transport. Modeling calculations were made to determine the risks to human population via these general pathways for the three postulated closure options for the New TNX Seepage Basin. Cost estimates for each closure option at the basin have also been prepared. An evaluation of the environmental impacts from the New TNX Seepage Basin indicate that the relative risks to human health and ecosystems for the postulated closure options are low. The transport of six chemical and one radionuclide constituents through the environmental pathways from the basin were modeled. The maximum chemical carcinogenic risk and the noncarcinogenic risk for the groundwater pathways were from exposure to trichloromethane and nitrate

    Full Text Available In the world, river basins often interwoven into two or more states or prefectures and because of that, disputes over water are common. Nevertheless, not all shared river basins are associated with water conflicts. Rivers in Japan and Malaysia play a significant role in regional economic development. They also play a significant role as water sources for industrial, domestic, agricultural, aquaculture, hydroelectric power generation, and the environment. The research aim is to determine the similarities and differences between the Sagami and Muda River Basins in order to have a better understanding of the governance needed for effectively implementing the lessons drawn from the Sagami River Basin for improving the management of the Muda River Basin in Malaysia. This research adopts qualitative and quantitative approaches. Semi-structured interviews were held with the key stakeholders from both basins and show that Japan has endeavored to present policy efforts to accommodate the innovative approaches in the management of their water resources, including the establishment of a river basin council. In Malaysia, there is little or no stakeholder involvement in the Muda River Basin, and the water resource management is not holistic and is not integrated as it should be. Besides that, there is little or no Integrated Resources Water Management, a pre-requisite for sustainable water resources. The results from this comparative study concluded that full support and participation from public stakeholders (meaning the non-government and non-private sector stakeholders is vital for achieving sustainable water use in the Muda River Basin. Integrated Water Resources Management (IWRM approaches such as the introduction of payments for ecosystems services and the development of river basin organization in the Muda River Basin should take place in the spirit of political willingness.

    Full Text Available One problem discussed by urban hydrology today is the draining influence of the modern cities over the natural drainage systems. The increasing urban areas and of their imperviousness all over theworld is linked to floods shape modifications and unpredicted systemic implications.  Generally, the draining influence of a city over its environment begins when it has a surface great enough to create an anthropic-generated runoff during a rain with enoughprecipitations to provoke waters accumulation into street torrents. The size, imperviousness, precipitations, drainage system and water consumption of the Suceava city are analysed in order to estimate the discharge of the city into Suceava river at various rainfalls. The article is structured as follows:1. Argumentation on the class separation between natural and anthropic torrential basins.2. Placing Suceava city as one of the torrential anthropic basins in Romania using basic arguments.3. Extending one of the argument, the importance of the rainfalls, in more detailed discussions (rainfall characteristics mainly, but also its cumulative effect with the floods on the Suceava river and the consumption of water in the city, with two scenarios. 4.

Conclusions, where measures are proposed in order to diminish the potential negative effects on environment and human society.This article is only an introduction to a more detailed analysis which will be complete with further field data.

  11. Salt disposal: Paradox Basin, Utah

    International Nuclear Information System (INIS)

    1983-04-01

    This report presents the findings of a study conducted for the National Waste Terminal Storage (NWTS) Program. Permanent disposal options are examined for salt resulting from the excavation of a waste repository in the bedded salt deposits of the Paradox Basin of southeastern Utah. The study is based on a repository salt backfill compaction of 60% of the original density which leaves a total of 8 million tons of 95% pure salt to be disposed of over a 30-year period. The feasibility, impacts, and mitigation methods are examined for five options: commercial disposal, permanent onsite surface disposal, permanent offsite disposal, deepwell injection, and ocean and Great Salt Lake disposal. The study concludes the following: Commercial marketing of all repository salt would require a subsidy for transportation to major salt markets. Permanent onsite surface storage is both economically and technically feasible. Permanent offsite disposal is technically feasible but would incur additional transportation costs. Selection of an offsite location would provide a means of mitigating impacts associated with surface storage at the repository site. Deepwell injection is an attractive disposal method; however, the large water requirement, high cost of development, and poor performance of similar operating brine disposal wells eliminates this option from consideration as the primary means of disposal for the Paradox Basin. Ocean disposal is expensive because of high transportation cost. Also, regulatory approval is unlikely. Ocean disposal should be eliminated from further consideration in the Paradox Basin. Great Salt Lake disposal appears to be technically feasible. Great Salt Lake disposal would require state approval and would incur substantial costs for salt transportation. Permanent onsite disposal is the least expensive method for disposal of all repository salt

    New SHRIMP radiogenic isotope dating on zircons in tuffs (280.8 ± 1.9 Ma) confirms the Early Permian (Artinskian) age of the uppermost section of the Tunas Formation. Tuff-rich levels in the Tunas Formation are exposed in the Ventana foldbelt of central Argentina; they are part of a deltaic to fluvial section corresponding to the late overfilled stage of the Late Paleozoic Sauce Grande foreland basin. Recent SHRIMP dating of zircons from the basal Choiyoi volcanics exposed in western Argentina yielded an age of 281.4 ± 2.5 Ma (Rocha-Campos et al., 2011). The new data for the Tunas tuffs suggest that the volcanism present in the Sauce Grande basin can be considered as the distal equivalent of the earliest episodes of the Choiyoi volcanism of western Argentina. From the palaeoclimatic viewpoint the new Tunas SHRIMP age confirms that by early Artinskian glacial conditions ceased in the Sauce Grande basin and, probably, in adajacent basins in western Gondwana.

In the man, some species as Ancylostoma caninum, A. braziliense and A. tubaeforme can cause cutaneous larva migrans, when the larvae infects of third period of stage penetrate actively the skin. The objective of this work was to detect the parasitism for ancylostomides in excrements of domiciliated and asymptomatic dogs in Campos dos Goytacazes, RJ, in view of the proximity of the conviviality of these animals with the man. With this intention, faecal samples of 68 dogs had been collected, being 30 (44.12% considered parasitized through stool parasitology using the method of Willis-Molley.

    KEY WORDS: Ancylostoma sp. feces, Willis-Mollay Method.

Dos 145 soros testados, 44 (30,34% foram positivos na hemaglutinação, com título igual ou superior a 1:16. Não foram observadas associações entre as caracterí sticas epidemiológicas examinadas, tais como hábitos alimentares (ingestão de carne bovina crua ou malpassada, vegetais crus/não lavados, produtos lácteos não pasteurizados ou contato constante com cães e a presença de anticorpos contra T. gondii, exceto pelo percentual significativamente maior de estudantes soropositivos que relataram ter contato freqüente com gatos (P=0,03.Serum samples obtained from students of the School of Veterinary Medicine, Universidade para o Desenvolvimento do Estado e da Região do Pantanal, Campo Grande, MS, Brazil, were examined for Toxoplasma gondii gondii antibodies. Serum samples from 44 (30.34% of the 145 veterinary students examined were positive on the hemagglutination test, yielding a titer of 1:16 or greater. There were no relations between the epidemiological characteristics examined, such as food habits (eating of raw or rare-cooked cattle meat, raw/uncleaned vegetables, unpasteurized dairy products, frequent contact with dogs and the presence of T. gondii antibodies, except for a significantly higher percentual of seropositive students that reported frequent contact with cats (P=0.03.

    Full Text Available This study aims to analyze purchase policies to fruits and vegetables in supermarkets in Campo Grande, Brazilian Midwest. Thirteen interviews were conducted with representatives from supermarkets, small, medium and large, responsible for purchasing fresh vegetables. By analyzing the responses obtained through interviews, we can observe that producers make almost the entire supply of fruits and vegetables in large supermarkets from other states, and the small and medium establishments usually buy more with the local producer. For retailers, the fruits and vegetables represent an important factor to create internal circulation of customers in stores and a factor of attraction of clients too, in addition, this products offer high profitability. For the supermarket, the fruits and vegetables locally produced are fresher and have lower comparative cost. However, supply regularity, the volume and variety offered by local producers are considered unsatisfactory.O presente estudo objetiva analisar as formas de compra dos supermercados para o abastecimento de hortaliças em Campo Grande. Foram realizadas treze entrevistas com representantes de supermercados de pequeno, médio e grande porte, responsáveis pelas compras destes produtos. Os resultados revelam que praticamente todo o fornecimento de hortaliças nos grandes supermercados é feito por produtores de outros estados, sendo que os estabelecimentos de pequeno e médio porte ainda conseguem abastecer-se satisfatoriamente com os produtores locais. Para os varejistas, o setor de hortaliças representa importante espaço de geração de tráfego interno de clientes nas lojas, sendo um fator de atração. Pode-se verificar, ainda, que as hortaliças produzidas localmente atendem ao requisito "frescor" e também possuem menor custo comparativo, porém, a regularidade no fornecimento, o volume e a variedade oferecida pelos produtores locais são considerados insatisfatórios.

  11. Basin Assessment Spatial Planning Platform

    Energy Technology Data Exchange (ETDEWEB)

    2017-07-26

    The tool is intended to facilitate hydropower development and water resource planning by improving synthesis and interpretation of disparate spatial datasets that are considered in development actions (e.g., hydrological characteristics, environmentally and culturally sensitive areas, existing or proposed water power resources, climate-informed forecasts). The tool enables this capability by providing a unique framework for assimilating, relating, summarizing, and visualizing disparate spatial data through the use of spatial aggregation techniques, relational geodatabase platforms, and an interactive web-based Geographic Information Systems (GIS). Data are aggregated and related based on shared intersections with a common spatial unit; in this case, industry-standard hydrologic drainage areas for the U.S. (National Hydrography Dataset) are used as the spatial unit to associate planning data. This process is performed using all available scalar delineations of drainage areas (i.e., region, sub-region, basin, sub-basin, watershed, sub-watershed, catchment) to create spatially hierarchical relationships among planning data and drainages. These entity-relationships are stored in a relational geodatabase that provides back-end structure to the web GIS and its widgets. The full technology stack was built using all open-source software in modern programming languages. Interactive widgets that function within the viewport are also compatible with all modern browsers.

    Full Text Available There are several programs for studying dynamical systems, but none of them is very useful for investigating basins and attractors of higher dimensional systems. Our goal in this paper is to show a new algorithm for finding even chaotic attractors and their basins for these systems. We present an implementation and examples for the use of this program.
