    Full Text Available Samples of a soft-bottom community from the continental slope of Campos Basin, off southeast Brazil, were obtained between 2001 and 2003 by the Research Vessel “Astro-Garoupa” with a 0.25 m2 box corer or by dredging with a Charcot dredge. A total of 177 samples were taken at depths ranging from 700 to 1950 m. Mollusks were present at all of the stations and among Gastropoda the Turridae showed the highest diversity. Within the family Cochlespirinae we found: Leucosyrinx tenoceras (Dall, 1889, L. verrillii (Dall, 1881, expanding the known distribution of the latter species farther south, and L.? subgrundifera (Dall, 1888, which is the first record of this species for the South Atlantic and the shallowest depth at which it has ever been found. Within the family Drilliinae we found Splendrillia centimata (Dall, 1889, also the first record of this species for the South Atlantic and its shallowest depth. Within the subfamily Oenopotinae we describe here three new species in the genus Oenopota Mörch, 1852: O. seraphina n. sp., O. diabula n. sp. and O. carioca n. sp.

    Full Text Available During the program “Environmental Characterization of the Campos Basin, RJ, Brazil”, from 2001 to 2003, samples were taken of soft bottoms from the continental slope of Campos Basin (off southeast Brazil by the Research Vessel “Astro-Garoupa” with a 0.25 m2 box corer or by dredging with a Charcot dredge; 117 stations with depths from 700 to 1950 m were sampled. There were molluscs in all samples, and among Gastropoda the Turridae showed the highest diversity. Here we present the results obtained for the subfamilies Mangeliinae, Taraninae and Clathurellinae. Two species were found within Mangeliinae: Benthomangelia cf. macra (Watson, 1881 and Benthomangelia enceladus n. sp. Within Taraninae only one undescribed species was found: Taranis tanata n. sp. Within Clathurellinae we found four species: Corinnaeturris leucomata (Dall, 1881, recorded for the first time in the South Atlantic; Corinnaeturris rhysa (Watson, 1881, extending its described depth range; Corinnaeturris angularis n. sp., Typhlomangelia nivalis (Lovén, 1846, expanding its known distribution farther south; and Drilliola pulchella (Verrill, 1880. The type material of Drilliola loprestiana (Calcara, 1841, previously considered lost, has been located and is illustrated here. Drilliola crispata (Cristofori and Jan, 1832 is considered to be a nomen dubium.

    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)

    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 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 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)

    There are significant coal resources in the northern regions of the Bowser basin in north-central British Columbia. However, the resource potential of the southern part of the basin has not been assessed, therefore the hydrocarbon potential is not known. Geological maps indicate several Mesozoic clastic and volcanic units across the southern part of the basin. Two stratigraphic intervals of the southern Bowser basin are considered to be potential source rocks within the Jurassic-Cretaceous strata. The fine-grained clastic rocks of the Bowser Lake Group contain significant amounts of carbonaceous material or organic matter. Well developed cleavage indicates that the rocks may be thermally over mature. This paper described potential reservoir rocks within the basin, along with their thermal maturation and conceptual play. 4 figs.

    Science.gov (United States)

    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

    Zhangzhou basin located at the Southeast margins of Asian plate is one of the largest geothermal fields in Fujian province, Southeast China. High-temperature natural springs and granite rocks are widely distributed in this region and the causes of geothermal are speculated to be involved the large number of magmatic activities from Jurassic to Cretaceous periods. To investigate the deep structure of Zhangzhou basin, magnetotelluric and gravity measurements were carried out and the joint inversion of magnetotelluric and gravity data delineated the faults and the granites distributions. The inversion results also indicated the backgrounds of heat reservoirs, heat fluid paths and whole geothermal system of the Zhangzhou basin. Combining with the surface geological investigation, the geophysical inversion results revealed that the faults activities and magma intrusions are the main reasons for the formation of geothermal resources of the Zhangzhou basin. Upwelling mantle provides enormous heats to the lower crust leading to metamorphic rocks to be partially melt generating voluminous magmas. Then the magmas migration and thermal convection along the faults warm up the upper crust. So finally, the cap rocks, basements and major faults are the three favorable conditions for the formation of geothermal fields of the Zhangzhou basin.

    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)

    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.

    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)

  11. Late Mesozoic basin and range tectonics and related magmatism in Southeast China

    2012-03-01

    Full Text Available During the Late Mesozoic Middle Jurassic–Late Cretaceous, basin and range tectonics and associated magmatism representative of an extensional tectonic setting was widespread in southeastern China as a result of Pacific Plate subduction. Basin tectonics consists of post-orogenic (Type I and intra-continental extensional basins (Type II. Type I basins developed in the piedmont and intraland during the Late Triassic to Early Jurassic, in which coarse-grained terrestrial clastic sediments were deposited. Type II basins formed during intra-continental crustal thinning and were characterized by the development of grabens and half-grabens. Graben basins were mainly generated during the Middle Jurassic and were associated with bimodal volcanism. Sediments in half-grabens are intercalated with rhyolitic tuffs and lavas and are Early Cretaceous in age with a dominance of Late Cretaceous–Paleogene red beds. Ranges are composed of granitoids and bimodal volcanic rocks, A-type granites and dome-type metamorphic core complexes. The authors analyzed lithological, geochemical and geochronological features of the Late Mesozoic igneous rock assemblages and proposed some geodynamical constraints on forming the basin and range tectonics of South China. A comparison of the similarities and differences of basin and range tectonics between the eastern and western shores of the Pacific is made, and the geodynamical evolution model of the Southeast China Block during Late Mesozoic is discussed. Studied results suggest that the basin and range terrane within South China developed on a pre-Mesozoic folded belt was derived from a polyphase tectonic evolution mainly constrained by subduction of the western Pacific Plate since the Late Mesozoic, leading to formation of various magmatism in a back-arc extensional setting. Its geodynamic mechanism can compare with that of basin and range tectonics in the eastern shore of the Pacific. Differences of basin and range

    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.

    WAC Chiba

    Full Text Available Benthic macroinvertebrates have many useful properties that make possible the use of these organisms as sentinel in biomonitoring programmes in freshwater. Combined with the characteristics of the water and sediment, benthic macroinvertebrates are potential indicators of environmental quality. Thus, the spatial occurrence of potentially toxic metals (Al, Zn, Cr, Co, Cu, Fe, Mn and Ni in the water, sediment and benthic macroinvertebrates samples were investigated in a sub-basin in the southeast of Brazil in the city of São Carlos, São Paulo state, with the aim of verifying the metals and environment interaction with benthic communities regarding bioaccumulation. Hypothetically, there can be contamination by metals in the aquatic environment in the city due to lack of industrial effluent treatment. All samples were analysed by the USEPA adapted method and processed in an atomic absorption spectrophotometer. The sub-basin studied is contaminated by toxic metals in superficial water, sediment and benthic macroinvertebrates. The Bioaccumulation Factor showed a tendency for metal bioaccumulation by the benthic organisms for almost all the metal species. The results show a potential human and ecosystem health risk, contributing to metal contamination studies in aquatic environments in urban areas.

  18. Review of potential host rocks for radioactive wasste disposal in the southeast United States: Triassic basin subregion

    International Nuclear Information System (INIS)

    1980-10-01

    Based on an evaluation of existing information, areas were identified within the Triassic basins of the southeastern United States with geologic properties considered favorable for containment of radioactive waste. The study region included both exposed and buried Triassic basins from Maryland to Georgia. These basins are long, narrow northeast-trending troughs filled with continental deposits derived from Paleozoic and Precambrian metamorphic and igneous rocks bordering the basins. The rocks are predominantly red in color and consist mainly of fanglomerates, conglomerates, arkosic sandstones, siltstones, claystones, shales, and argillites. The investigation identified 14 exposed and 5 buried basins within the study region. Candidate areas for further investigation were identified which meet the broad general criteria for tectonic stability, slow ground water movement, and long flow paths to the biosphere. These include: the Danville Triassic Basin in Virginia; the Dan River, Durham, and Wadesboro Triassic Basins in North Carolina; and the buried Florence and Dunbarton Triassic Basins in South Carolina. Other rock types in the southeast may prove more or less suitable as host rocks for a repository, but the available data suggest that the argillaceous Triassic rocks offer sufficient promise to be considered for additional study

    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)

  20. Impact of Climatic Variability on Hydropower Reservoirs in the Paraiba Basin, Southeast of Brazil

    2002-05-01

    During 2000/2001, a severe drought greatly reduced the volume of water available to Brazilian hydropower plants and lead to a national water rationing plan. To undestand the potential for climatic change in hydrological regimes and its impact on hydropower we chose the Paraiba Basin located in Southeast Brazil. Three important regional multi-purpose reservoirs are operating in this basin. Moreover, the Paraiba River is of great economic and environmental importance and also constitutes a major corridor connecting the two cities of Sao Paulo and Rio de Janeiro. We analyzed monthly and daily records for rainfall, streamflow and temperature using regression and variance analysis. Rainfall records do not show any significant trend since the 1930s/1940s. By contrast, analysis of seasonal patterns show that in the last twenty years rainfall has increased during autumn and winter (dry season) and decreased during spring and summer (rainy season). Comparison between rainfall and streaflow, from small catchment without man-made influences, shows a more pronounced deficit in streamflow when compared with rainfall. The shifts in seasonal rainfall could indicate a tendency towards a more uniform rainfall pattern and could serve to reduce the streamflow. However, the largest upward trends in temperature were found in the driest months (JJA). The increase in rainfall would not be sufficient to overcome increased of evaporation expect to the same period. Instead, such increase in evaporation could create an over more pronounced streamflow deficit. Climatic variability could be reducing water availability in these reservoirs especially in the driest months. To reduce the uncertainties in hydrological predictions, planners need to incorporate climatic variability, at the catchment scale, in order to accomodate the new conditions resulting from these changes.

    Ensemble flood forecasting driven by numerical weather prediction products is becoming more commonly used in operational flood forecasting applications.In this study, a hydrological ensemble flood forecasting system based on Variable Infiltration Capacity (VIC) model and quantitative precipitation forecasts from TIGGE dataset is constructed for Lanjiang Basin, Southeast China. The impacts of calibration strategies and ensemble methods on the performance of the system are then evaluated.The hydrological model is optimized by parallel programmed ɛ-NSGAII multi-objective algorithm and two respectively parameterized models are determined to simulate daily flows and peak flows coupled with a modular approach.The results indicatethat the ɛ-NSGAII algorithm permits more efficient optimization and rational determination on parameter setting.It is demonstrated that the multimodel ensemble streamflow mean have better skills than the best singlemodel ensemble mean (ECMWF) and the multimodel ensembles weighted on members and skill scores outperform other multimodel ensembles. For typical flood event, it is proved that the flood can be predicted 3-4 days in advance, but the flows in rising limb can be captured with only 1-2 days ahead due to the flash feature. With respect to peak flows selected by Peaks Over Threshold approach, the ensemble means from either singlemodel or multimodels are generally underestimated as the extreme values are smoothed out by ensemble process.

    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.

    Full Text Available Total phosphorus concentration was used to define the trophic state of the main sub-basins of the middle Rio Doce, in Minas Gerais State (southeast Brazil and physical, chemical, and microbiological variables of water were analyzed during 2000 to 2001. The study evaluated changes in water quality caused by seasonality and human activities. Water temperature, conductivity, pH, total alkalinity, dissolved oxygen, and concentrations of NH4-N, NO2-N, NO3-N, total-N, PO4-P, total-P, DOC, and chlorophyll-a were measured in seven rivers stretches (sampling stations. Total yeasts, faecal and total coliforms, and heterotrophic bacteria were also determined. The studied areas were considered to be under oligotrophic to eutrophic conditions. The variables that presented highest positive correlation with faecal coliforms were total-P and total-N, and heterotrophic bacteria density was identified as a good parameter to differentiate the ecosystems. These results suggested the inclusion of the trophic level and the distinct activities within a watershed as important elements when proposing conservation and restoration areas.A concentração de fósforo total foi utilizada para determinar o grau de trofia das principais sub-bacias do trecho médio da bacia do Rio Doce, em Minas Gerais, e variáveis físicas, químicas e microbiológicas da água foram analisadas nos períodos de chuva e seca durante os anos de 2000 e 2001. O estudo visou determinar mudanças na qualidade da água causadas pela sazonalidade e por diferentes atividades antrópicas. As áreas estudadas variaram de oligotróficas a eutróficas. As variáveis que apresentaram as maiores correlações positivas com a densidades de coliformes fecais foram as concentrações de nitrogênio e fósforo total, além disso, bactérias heterotróficas mostrou-se capaz de diferenciar os ambientes.

    The Menomonee River drainage basin in southeast Wisconsin is undergoing changes that may affect water quality. Several rehabilitation and flood-management projects are underway, including removal of concrete channels and the construction of floodwater retention basins. The city of Waukesha may begin discharging treated wastewater into Underwood Creek, thus approximately doubling the current base-flow discharge. In addition, the headwater basins, historically dominated by agriculture and natural areas, are becoming increasingly urbanized.

    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)

    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)

    The Southeast Watershed Hydrology Research Center (SEWHRC) was established in 1966 by order of the U.S. Senate "to identify and characterize those elements that control the flow of water from watersheds in the southeast". A 129 sq.mi. area within the headwaters of Little River Watershed (LRW) in central south Georgia was instrumented to provide data for evaluating and characterizing Coastal Plain hydrologic processes and for development and testing of prediction methodologies for use in ungaged watersheds in regions of low topographic relief. Pesticide analytical capabilities were added in 1976, and inorganic chemistry and sediment transport research were expanded. In 1980, the Center was renamed as the Southeast Watershed Research Laboratory (SEWRL), and laboratories were constructed for nutrient analysis and soil physics. A pesticide analysis laboratory was constructed in 1987. In the early 1990s, a hydraulics laboratory was established for sediment and chemical transport studies, and research on riparian buffers was expanded. The SEWRL research program continues to focus on hydrologic and environmental concerns. Major components of the program are hydrology, pesticides behavior, buffer systems, animal waste management, erosion, remote sensing of watershed condition, and relationships between site-specific agricultural management (BMPs) and small-to-large watershed response. SEWRL's program will be expanded over the next five years to include two additional watersheds comparable in size and instrumentation to the LRW; nesting the LRW within the full Little River drainage and subsequently...all three watersheds within the full Suwannee Basin; and mapping and quantifying irrigation water removals within the Suwannee Basin. We will instrument the three intensive study watersheds and the full Suwannee Basin to provide real-time characterization of precipitation, soil moisture, hydrologic flow, and water quality at a range of spatial and temporal scales.

    Streamflow distribution maps for the Cannon River and St. Louis River drainage basins were developed by the U.S. Geological Survey, in cooperation with the Legislative-Citizen Commission on Minnesota Resources, to illustrate relative and cumulative streamflow distributions. The Cannon River was selected to provide baseline data to assess the effects of potential surficial sand mining, and the St. Louis River was selected to determine the effects of ongoing Mesabi Iron Range mining. Each drainage basin (Cannon, St. Louis) was subdivided into nested drainage basins: the Cannon River was subdivided into 152 nested drainage basins, and the St. Louis River was subdivided into 353 nested drainage basins. For each smaller drainage basin, the estimated volumes of groundwater discharge (as base flow) and surface runoff flowing into all surface-water features were displayed under the following conditions: (1) extreme low-flow conditions, comparable to an exceedance-probability quantile of 0.95; (2) low-flow conditions, comparable to an exceedance-probability quantile of 0.90; (3) a median condition, comparable to an exceedance-probability quantile of 0.50; and (4) a high-flow condition, comparable to an exceedance-probability quantile of 0.02.Streamflow distribution maps were developed using flow-duration curve exceedance-probability quantiles in conjunction with Soil-Water-Balance model outputs; both the flow-duration curve and Soil-Water-Balance models were built upon previously published U.S. Geological Survey reports. The selected streamflow distribution maps provide a proactive water management tool for State cooperators by illustrating flow rates during a range of hydraulic conditions. Furthermore, after the nested drainage basins are highlighted in terms of surface-water flows, the streamflows can be evaluated in the context of meeting specific ecological flows under different flow regimes and potentially assist with decisions regarding groundwater and surface

    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).

  15. Seasonal study of contamination by metal in water and sediment in a sub-basin in the southeast of Brazil

    WAC. Chiba

    Full Text Available The spatial and temporal occurrence of heavy metals (Al, Cd, Pb, Zn, Cr, Co, Cu, Fe, Mn and Ni in water and sediment samples was investigated in a sub-basin in the southeast of Brazil (São Carlos, SP. All samples were analysed using the USEPA adapted metal method and processed in an atomic absorption spectrophotometer. The discriminant analysis demonstrated that there are significant seasonal differences of metal distribution in the water data, but there are no differences to sediment. The basin studied has high levels of contamination by toxic metals in superficial water and sediment. The superficial water, in the rainy season, presented high levels of Cr, Ni, Pb and Cd, while in the dry season it presented high levels of Zn and Ni. The Principal Component Analysis demonstrated that the season has a huge influence on the levels, types and distribution of metals found in water. The source of contamination was probably diffuse, due to products such as batteries and fluorescent lamps, whose dump discharge can contaminate the bodies of water in the region in the rainy season. Due to fires from the harvest of sugar cane, high levels of Zn were found into the environment, in the dry season.

  16. Rainfall characteristics and thresholds for periglacial debris flows in the Parlung Zangbo Basin, southeast Tibetan Plateau

    The Parlung Zangbo Basin in the southeastern Tibet Plateau is affected by the summer monsoon from the Indian Ocean, which produces large rainfall gradients in the basin. Rainfall data during 2012-2015 from five new meteorological stations are used to analyse the rainfall characteristics. The daily rainfall, rainfall duration, mean rainfall intensity, and peak rainfall intensity are consistent, but sometimes contrasting. For example, these values decrease with increasing altitude, and the gradient is large downstream and small upstream, respectively. Moreover, the rainfall intensity peaks between 01:00 and 06:00 and increases during the afternoon. Based on the analysis of 14 debris flow cases in the basin, differences in the rainfall threshold differ depending on the location as sediment varieties. The sediment in the middle portions of the basin is wet and well structured; thus, long-duration, high-intensity rainfall is required to generate debris flows. Ravels in the upstream area are arid and not well structured, and short-duration rainfall is required to trigger debris flows. Between the above two locations, either long-duration, low-intensity rainfall or short-duration, high-intensity rainfall could provoke debris flows. Clearly, differences in rainfall characteristics and rainfall thresholds that are associated with the location must be considered in debris flow monitoring and warnings.

    Understanding factors driving diversity across biodiversity hotspots is critical for formulating conservation priorities in the face of ongoing and escalating environmental deterioration. While biodiversity hotspots encompass a small fraction of Earth's land surface, more than half the world's plants and two-thirds of terrestrial vertebrate species are endemic to these hotspots. Tropical Southeast (SE) Asia displays extraordinary species richness, encompassing four biodiversity hotspots, though disentangling multiple potential drivers of species richness is confounded by the region's dynamic geological and climatic history. Here, we use multilocus molecular genetic data from dense multispecies sampling of freshwater fishes across three biodiversity hotspots, to test the effect of Quaternary climate change and resulting drainage rearrangements on aquatic faunal diversification. While Cenozoic geological processes have clearly shaped evolutionary history in SE Asian halfbeak fishes, we show that paleo-drainage re-arrangements resulting from Quaternary climate change played a significant role in the spatiotemporal evolution of lowland aquatic taxa, and provide priorities for conservation efforts.

    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.

    One of the important ore-concentrated areas of carbonaceous-siliceous-pelitic rock type uranium deposits is the Southeast continental margin of Yangtze plate. Sedimentary-exogenously transformed type and sedimentary- hydrothermal superimposed transformed type uranium deposits are always distributed at or near the edge of down-faulted red ba sins. In this paper, the distributions of the deposits are analyzed with the relation to down-faulted red basins. The connective effect and ore-controlling mechanism are proposed of carbonaceous-siliceous-pelitic rock type uranium deposits with marginal fractures of red basins. (authors)

  20. River-Basin Politics and the Rise of Ecological and Transnational Democracy in Southeast Asia and Southern Africa

    Directory of Open Access Journals (Sweden)

    Chris Sneddon

    2008-06-01

    Full Text Available In recent years, debates over 'deliberative', 'transnational' and 'ecological' democracy have proliferated, largely among scholars engaged in discussions of modernisation, globalisation and political identity. Within this broad context, scholars and practitioners of environmental governance have advanced the argument that a democratic society will produce a more environmentally conscious society. We want to make a volte-face of this argument and ask: to what extent does engagement with environmental politics and, specifically, water politics, contribute to processes of democratisation? After reviewing some of the contributions to debates over 'ecological' and 'transnational' democracy, we explore this question within the context of conflicts over river-basin development in Southeast Asia and southern Africa. We argue that there are multiple pathways to democratisation and that, in some cases, the environment as a political issue does constitute a significant element of democratisation. But notions of 'ecological' and 'transnational' democracy must embody how both 'environment' and 'the transnational', as mobilised by specific social movements in specific historical and geographical circumstances, are politically constructed.

    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 coastal basin deposit in the Lian River plain is among the thickest Quaternary sequences along the southeastern coast of China. The clastic sediment accumulated in a variety of environmental settings including fluvial, channel, estuary/coastal and marine conditions. Detailed investigation of lithofacies, grain-size distributions, magnetic susceptibility, microfossils and chronology of marine core CN01, compared with regional cores, and combined with offshore seismic reflection profiles, has allowed us to correlate the spatial stratigraphy in the inner and outer plain and the seismic units. Grain size distribution analysis of core CN-01 through compositional data analysis and multivariate statistics were applied to clastic sedimentary facies and sedimentary cycles. Results show that these methods are able to derive a robust proxy information for the depositional environment of the Lian River plain. We have also been able to reconstruct deltaic evolution in response to marine transgressions. On the basis of dating results and chronostratigraphy, the estimated age of the onset of deposition in the Lian River coastal plain was more than 260 kyr BP. Three transgressive sedimentary cycles revealed in many regional cores support this age model. Detailed lithological and microfossil studies confirm that three marine (M3, M2 and M1) and three terrestrial (T3, T2 and T1) units can be distinguished. Spatial correlation between the inner plain, outer plain (typical cores characterized by marine transgression cycles) and offshore seismic reflectors reveals coherent sedimentary sequences. Two major boundaries (unconformity and erosion surfaces) can be recognized in the seismic profiles, and these correspond to weathered reddish and/or variegated clay in the study core, suggesting that Quaternary sediment changes on the Lian River plain were largely controlled by sea-level variations and coastline shift during glacial/interglacial cycles.

    Carbon dioxide (CO 2 ) capture and storage is considered to be a viable strategy to reduce the amount of greenhouse gases released to the atmosphere. When assessing the feasibility of current or future CO 2 storage projects, mineral trapping within a reservoir is considered as a key mechanism for the permanent sequestration of CO 2 . There are many occurrences worldwide, where natural CO 2 has been trapped in geological reservoirs. These natural CO 2 analogues provide a unique opportunity to study the reactivity, due to CO 2 interactions, which occurred in the reservoirs over a geologic timeframe. Therefore, the study of analogous natural CO 2 -rich reservoirs, which act as long-term laboratories, are an important part of the assessment of the long-term geochemical effects of geological CO 2 storage. This paper referred to 2 natural CO 2 sites studied under the Natural Analogues for the Storage of CO2 in the Geological Environment (NASCENT) Project. The Montmiral reservoir in France's Southeast Basin is a high-temperature and high-pressure reservoir at great depth (100 degrees C and 36 MPa). The Messokampos reservoir in Greece's Florina Basin is a shallow, low temperature and low-pressure reservoir (25 degrees C and 0.5 MPa). Both are sandstone reservoirs, and feldspar alteration is the key interaction in both cases between dissolved CO 2 , the formation water and the reservoir rock. Both natural analogues were studied in detail petrographically and through geochemical modelling in order to characterize and explain the water-rock-gas interactions in the different geological contexts. The purpose was to assess the consequences of these interactions on CO 2 storage capacity and porosity of the host rock. It was concluded that the reservoir's temperature and pressure conditions determine the impact of CO 2 interactions, with elevated temperatures significantly increasing the reaction rates of mineral-trapping reactions. This is particularly significant when choosing

    Ensemble flood forecasts by hydrological models using numerical weather prediction products as forcing data are becoming more commonly used in operational flood forecasting applications. In this study, a hydrological ensemble flood forecasting system comprised of an automatically calibrated Variable Infiltration Capacity model and quantitative precipitation forecasts from TIGGE dataset is constructed for Lanjiang Basin, Southeast China. The impacts of calibration strategies and ensemble methods on the performance of the system are then evaluated. The hydrological model is optimized by the parallel programmed ε-NSGA II multi-objective algorithm. According to the solutions by ε-NSGA II, two differently parameterized models are determined to simulate daily flows and peak flows at each of the three hydrological stations. Then a simple yet effective modular approach is proposed to combine these daily and peak flows at the same station into one composite series. Five ensemble methods and various evaluation metrics are adopted. The results show that ε-NSGA II can provide an objective determination on parameter estimation, and the parallel program permits a more efficient simulation. It is also demonstrated that the forecasts from ECMWF have more favorable skill scores than other Ensemble Prediction Systems. The multimodel ensembles have advantages over all the single model ensembles and the multimodel methods weighted on members and skill scores outperform other methods. Furthermore, the overall performance at three stations can be satisfactory up to ten days, however the hydrological errors can degrade the skill score by approximately 2 days, and the influence persists until a lead time of 10 days with a weakening trend. With respect to peak flows selected by the Peaks Over Threshold approach, the ensemble means from single models or multimodels are generally underestimated, indicating that the ensemble mean can bring overall improvement in forecasting of flows.

    In spite of the growing interest in Late Ordovician to the Early Silurian Wufeng–Longmaxi black shale for gas production in the southeast of the Sichuan Basin, little data is available on the acoustic properties of these shale reservoirs. The dynamic elastic properties of a suite of shales from this formation with different organic matter content were measured using the ultrasonic transmission technique at a range of confining pressures. The mineralogical features and reservoir space types were studied with the goal of analyzing their influence on the acoustic properties of the shale samples. The TOC (total organic content) is found to have a positive correlation with the quartz content and a negative correlation with the clay content. Organic matter pores and inter-crystal micro-pores are the main pore types. Organic-rich shales show a low P-wave impedance (Ip) and Vp/Vs ratio due to relatively higher TOC and quartz content; nonetheless, high P-wave (Ip) is also observed when the quartz content is very high resulting from the variation of load-bearing grains. The velocities and anisotropy of different shale samples show varying pressure dependence. A strong positive correlation is found between the anisotropy and the clay content. Three different types of microfabric can be observed in the shale samples, giving a qualitative explanation for the correlation between the anisotropy and the clay content. The occurrence of preferential alignment of the clay minerals requires that the clay content exceeds a critical volume, and this value is about 25%–30% in this study. (paper)

    than 80 % of the major dust deposition events are recorded at only one station, suggesting that the dust provenance, transport and deposition processes (i.e. wet vs. dry of dust are different and specific for the different deposition sites in the Mediterranean studied area. The results tend to indicate that wet deposition is the main form of deposition for mineral dust in the western Mediterranean basin, but the contribution of dry deposition (in the sense that no precipitation was detected at the surface is far from being negligible, and contributes 10 to 46 % to the major dust deposition events, depending on the sampling site.

    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.

    The southeastern United States is home to a diverse assemblage of snakes, but only one species, the Rough Greensnake (Opheodrys aestivus), is considered specialized for a predominantly arboreal lifestyle. Other species, such as Ratsnakes (genus Pantherophis) and Ribbonsnakes/Gartersnakes (genus Thamnophis), are widely known to climb into vegetation and trees. Some explanations given for snake climbing behavior are foraging, thermoregulation, predator avoidance, and response to flood. Reports of arboreality in snake species typically not associated with life in the trees (such as terrestrial, aquatic, and even fossorial species) usually come from single observations, with no knowledge of prevalence of the behavior. Here, we report on arboreality of snake species detected during 8 years of night surveys in the Atchafalaya Basin of south-central Louisiana and 5+ years of night surveys in Big Thicket National Preserve in southeast Texas. We recorded a total of 1,088 detections of 19 snake species between the two study areas, with 348 detections above ground level (32%). The Rough Greensnake and Western Ribbonsnake (Thamnophis proximus) accounted for nearly 75% of total arboreal detections among the two study areas. However, with one exception, all snake species detected more than once between both study areas had at least one arboreal detection. These observations demonstrate that snakes with widely varying natural histories may be found in the trees at night, and for some species, this behavior may be more common than previously believed.

    By comprehensive analysis on informations of regional geology and evaluating drillhole works of uranium resources in the southeast of Songliao basin, lithofacies-palaeogeography features, lithologies and sandbody characteristics of target layes in Quantou formation, Yaojia formation and Sifangtai formation have been basically found out. By research on geochemical environment of rocks in target layez, types of original geochemistry and epigenetic alteration have been identified and classified. The types of original geochemistry have been divided into types of original oxidation and original reduction, and the types of epigenetic alteration have been divided into types of reduction by oil-gas and coalbed gas and epigenetic oxidation. By comparative study on mineral and chemical characteristics of original geochemistry and epigenetic oxidation, identification marks for oil-gas and coalbed gas reduced epigenetic oxidation have been proposed. It is proposed that uranium was strongly pre-concentrated in original sandstone that bearing carboniferous matter, and reduction by oil-gas and coalbed gas made uranium superimpose and concentrate in alterated rocks.

    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)

    We measured the occurrence and seasonal variations of glyphosate and its metabolite, aminomethylphosphonic acid (AMPA), in different environmental compartments within the limits of an agricultural basin. This topic is of high relevance since glyphosate is the most applied pesticide in agricultural systems worldwide. We were able to quantify the seasonal variations of glyphosate that result mainly from endo-drift inputs, that is, from direct spraying either onto genetically modified (GM) crops (i.e., soybean and maize) or onto weeds in no-till practices. We found that both glyphosate and AMPA accumulate in soil, but the metabolite accumulates to a greater extent due to its higher persistence. Knowing that glyphosate and AMPA were present in soils (> 93% of detection for both compounds), we aimed to study the dispersion to other environmental compartments (surface water, stream sediments, and groundwater), in order to establish the degree of non-point source pollution. Also, we assessed the relationship between the water-table depth and glyphosate and AMPA levels in groundwater. All of the studied compartments had variable levels of glyphosate and AMPA. The highest frequency of detections was found in the stream sediments samples (glyphosate 95%, AMPA 100%), followed by surface water (glyphosate 28%, AMPA 50%) and then groundwater (glyphosate 24%, AMPA 33%). Despite glyphosate being considered a molecule with low vertical mobility in soils, we found that its detection in groundwater was strongly associated with the month where glyphosate concentration in soil was the highest. However, we did not find a direct relation between groundwater table depth and glyphosate or AMPA detections. This is the first simultaneous study of glyphosate and AMPA seasonal variations in soil, groundwater, surface water, and sediments within a rural basin.

    Groundwater flow is an important control on subsurface evaporite (salt) dissolution. Salt dissolution can drive faulting and associated subsidence on the land surface and increase salinity in groundwater. This study aims to understand the groundwater flow system of Gypsum Canyon watershed in the Paradox Basin, Utah, USA, and whether or not groundwater-driven dissolution affects surface deformation. The work characterizes the groundwater flow and solute transport systems of the watershed using a three-dimensional (3D) finite element flow and transport model, SUTRA. Spring samples were analyzed for stable isotopes of water and total dissolved solids. Spring water and hydraulic conductivity data provide constraints for model parameters. Model results indicate that regional groundwater flow is to the northwest towards the Colorado River, and shallow flow systems are influenced by topography. The low permeability obtained from laboratory tests is inconsistent with field observed discharges, supporting the notion that fracture permeability plays a significant role in controlling groundwater flow. Model output implies that groundwater-driven dissolution is small on average, and cannot account for volume changes in the evaporite deposits that could cause surface deformation, but it is speculated that dissolution may be highly localized and/or weaken evaporite deposits, and could lead to surface deformation over time.

    2007-01-01

    Natural gas can have two distinct origins, biogenic and thermogenic sources. This paper investigates the types and maturities of natural gas present in the SE Columbus basin, offshore Trinidad. The chemical composition and the isotope ratios of C and H were determined for approximately 100 samples of natural gas from eight areas within the SE Columbus basin. These compositions and isotopic data are interpreted to identify the origins of gas (biogenic, thermogenic) and maturity. The data showed that the gases in the SE Columbus basin are of both biogenic and thermogenic origin with a trend of mainly thermogenic to mixed to biogenic when moving from SW to NE across the basin. This trend suggests differential burial of the source rock. The presence of mixed gas indicates there was migration of gas in the basin resulting in deeper thermogenic gas mixing with shallow biogenic gas

    Ontong Java Plateau(OJP) in the western Pacific Ocean is one of the largest oceanic plateau in the world. Radioactive ages of drilling samples indicate that the most part of the OJP was emplaced about 122 Ma (Mahoney et al., 1993). Taylor (2006) proposed that the OJP formed as a single large volcanic province together with the Manihiki and Hikurangi plateaus. OJP is surrounding by East Mariana, Pigafetta, Nauru, Ellice, Stewart, and Lyra basins. The East Mariana and Pigafetta basins were formed at the Pacific-Izanagi ridge and the Nauru basin was formed at Pacific-Phoenix ridges (Nakanishi et al., 1992). The tectonic history of the Ellice, Stewart, and Lyra basins is still unknown because of lack of magnetic anomaly lineations. Tectonic setting during the OJP formation is thus a matter of controversy. To expose the tectonic setting of the Ellice, Stewart, and Lyra basins, we conducted the Multi-Channel Seismic (MCS) survey in the basins during the research cruise by R/V Mirai of JAMSTEC in 2014. We present our preliminary results of the MCS survey in the Stewart basin(SB) and Ellice Basin(EB). After the regular data processing, we compared the seismic facies of MCS profile with DSDP Site 288 and ODP Site 1184 to assign ages to seismic reflectors. Our processing exposed several remarkable structures in the basins. The graben structures deformed only the igneous basement in the northwestern and northeastern and southwestern margins of the SB. This suggests the graben structures were formed before sedimentary layer deposited. Taylor (2006) proposed that the basin was formed by the NW-SE rifting during the separation of OJP and Manihiki Plateau around 120 Ma. Neal (1997) proposed that the NE-SW rifting formed the basin around 80 Ma. Our study supports the rifting model proposed by Neal et al. (1997) because the displacement of graben in northeastern and southwestern margins of the SB is larger than that in northwestern of the SB. We found several igneous diapirs in the

    We review the skill of thirty coupled climate models participating in the Coupled Model Intercomparison Project Phase 5 (CMIP5) in terms of reproducing properties of the seasonal cycle of precipitation over the major river basins of South and Southeast Asia (Indus, Ganges, Brahmaputra and Mekong) for the historical period (1961-2000). We also present how these models represent the impact of climate change by the end of century (2061-2100) under the extreme scenario RCP8.5. First, we assess the models' ability to reproduce the observed timings of the monsoon onset and the rate of rapid fractional accumulation (RFA) slope — a measure of seasonality within the active monsoon period. Secondly, we apply a threshold-independent seasonality index (SI) — a multiplicative measure of precipitation (P) and extent of its concentration relative to uniform distribution (relative entropy — RE). We apply SI distinctly over the monsoonal precipitation regime (MPR), westerly precipitation regime (WPR) and annual precipitation. For the present climate, neither any single model nor the multi-model mean performs best in all chosen metrics. Models show overall a modest skill in suggesting right timings of the monsoon onset while the RFA slope is generally underestimated. One third of the models fail to capture the monsoon signal over the Indus basin. Mostly, the estimates for SI during WPR are higher than observed for all basins. When looking at MPR, the models typically simulate an SI higher (lower) than observed for the Ganges and Brahmaputra (Indus and Mekong) basins, following the pattern of overestimation (underestimation) of precipitation. Most of the models are biased negative (positive) for RE estimates over the Brahmaputra and Mekong (Indus and Ganges) basins, implying the extent of precipitation concentration for MPR and number of dry days within WPR lower (higher) than observed for these basins. Such skill of the CMIP5 models in representing the present-day monsoonal

    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.

    In 2008, the U.S. Geological Survey and the Milwaukee Metropolitan Sewerage District initiated a study to develop regression models to estimate real-time concentrations and loads of chloride, suspended solids, phosphorus, and bacteria in streams near Milwaukee, Wisconsin. To collect monitoring data for calibration of models, water-quality sensors and automated samplers were installed at six sites in the Menomonee River drainage basin. The sensors continuously measured four potential explanatory variables: water temperature, specific conductance, dissolved oxygen, and turbidity. Discrete water-quality samples were collected and analyzed for five response variables: chloride, total suspended solids, total phosphorus, Escherichia coli bacteria, and fecal coliform bacteria. Using the first year of data, regression models were developed to continuously estimate the response variables on the basis of the continuously measured explanatory variables. Those models were published in a previous report. In this report, those models are refined using 2 years of additional data, and the relative improvement in model predictability is discussed. In addition, a set of regression models is presented for a new site in the Menomonee River Basin, Underwood Creek at Wauwatosa. The refined models use the same explanatory variables as the original models. The chloride models all used specific conductance as the explanatory variable, except for the model for the Little Menomonee River near Freistadt, which used both specific conductance and turbidity. Total suspended solids and total phosphorus models used turbidity as the only explanatory variable, and bacteria models used water temperature and turbidity as explanatory variables. An analysis of covariance (ANCOVA), used to compare the coefficients in the original models to those in the refined models calibrated using all of the data, showed that only 3 of the 25 original models changed significantly.

    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.

    In order to design adaptive strategies to global change we need to assess the future impact of climate change on water resources, which depends on precipitation and temperature series in the systems. The objective of this work is to generate future climate series in the "Alto Genil" Basin (southeast Spain) for the period 2071-2100 by perturbing the historical series using different statistical methods. For this targeted we use information coming from regionals climate model simulations (RCMs) available in two European projects, CORDEX (2013), with a spatial resolution of 12.5 km, and ENSEMBLES (2009), with a spatial resolution of 25 km. The historical climate series used for the period 1971-2000 have been obtained from Spain02 project (2012) which has the same spatial resolution that CORDEX project (both use the EURO-CORDEX grid). Two emission scenarios have been considered: the Representative Concentration Pathways (RCP) 8.5 emissions scenario, which is the most unfavorable scenario considered in the fifth Assessment Report (AR5) by the Intergovernmental Panel on Climate Change (IPCC), and the A1B emission scenario of fourth Assessment Report (AR4). We use the RCM simulations to create an ensemble of predictions weighting their information according to their ability to reproduce the main statistic of the historical climatology. A multi-objective analysis has been performed to identify which models are better in terms of goodness of fit to the cited statistic of the historical series. The ensemble of the CORDEX and the ENSEMBLES projects has been finally created with nine and four models respectively. These ensemble series have been used to assess the anomalies in mean and standard deviation (differences between the control and future RCM series). A "delta-change" method (Pulido-Velazquez et al., 2011) has been applied to define future series by modifying the historical climate series in accordance with the cited anomalies in mean and standard deviation.

    Full Text Available Teaching about Southeast Asia to undergraduates at an American liberal arts college presents several challenges. At my institution, it is the only course on the region in the curriculum; thus no preparation, and no follow-up. I have therefore struggled with the approach that I should take–pulled between a wish for students to gain an empirical understanding of Southeast Asian life, and a desire to have them learn the concepts and theories of critical inquiry. Obviously I am still learning how to successfully accomplish such an ambitious undertaking.

    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)

    Full Text Available In the Camamu-Almada basin, marine fishery is exclusively small-scale, with several structural deficiencies such as boats with low or absent navigational technology, lack of credit and low income. Local fishers complain that shrimp and lobster trawling fishing is the main factor responsible for low stock abundance, but they still persist in these activities as these two species command the highest market prices. So they feel that the target species are already over-fished. We suggest that proper management action, alternative ways of income generation and the payment of job insurance would help to mitigate the problem.Na bacia Camamu-Almada, as pescarias marinhas são exclusivamente de pequena-escala, com várias deficiências estruturais: com barcos quase sem nenhuma tecnologia de auxílio à navegação, falta de crédito e baixa lucratividade. Os pescadores locais reclamam que a pesca de arrasto dirigida a camarões e lagosta é a principal responsável pela baixa abundância dos estoques preferenciais, mas como eles ainda têm alto preço no mercado, essa estratégia de pesca ainda persiste. Assim, eles percebem que esses estoques estão sobre-pescados. Sugerimos que medidas apropriadas de manejo local, ocupações alternativas e o pagamento do seguro desemprego em dia para os pescadores ajudariam a mitigar essa situação.

    Full Text Available The Mexican state built a complex and thorough system of agreements with the countries that integrate the Pacific Basin. Despite this effort, there is an important and increasing deficit in commercial exchange with the Asian Southeast Nations. The global balance trade compensates this inequity with the sur-plus set up with the United States of America. There are a lot of aspects that contribute to the explanation of these phenomena, but here it will be take into consideration just the important matters, in order to explain why the Mexican exports have the "natural" tendency to satisfy some UsA demands, which is still the mayor world importer.

    Abstract 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 ...

    2015-01-01

    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.

  17. Bottom water circulation in Cascadia Basin

    Science.gov (United States)

    Hautala, Susan L.; Paul Johnson, H.; Hammond, Douglas E.

    2009-10-01

    A combination of beta spiral and minimum length inverse methods, along with a compilation of historical and recent high-resolution CTD data, are used to produce a quantitative estimate of the subthermocline circulation in Cascadia Basin. Flow in the North Pacific Deep Water, from 900-1900 m, is characterized by a basin-scale anticyclonic gyre. Below 2000 m, two water masses are present within the basin interior, distinguished by different potential temperature-salinity lines. These water masses, referred to as Cascadia Basin Bottom Water (CBBW) and Cascadia Basin Deep Water (CBDW), are separated by a transition zone at about 2400 m depth. Below the depth where it freely communicates with the broader North Pacific, Cascadia Basin is renewed by northward flow through deep gaps in the Blanco Fracture Zone that feeds the lower limb of a vertical circulation cell within the CBBW. Lower CBBW gradually warms and returns to the south at lighter density. Isopycnal layer renewal times, based on combined lateral and diapycnal advective fluxes, increase upwards from the bottom. The densest layer, existing in the southeast quadrant of the basin below ˜2850 m, has an advective flushing time of 0.6 years. The total volume flushing time for the entire CBBW is 2.4 years, corresponding to an average water parcel residence time of 4.7 years. Geothermal heating at the Cascadia Basin seafloor produces a characteristic bottom-intensified temperature anomaly and plays an important role in the conversion of cold bottom water to lighter density within the CBBW. Although covering only about 0.05% of the global seafloor, the combined effects of bottom heat flux and diapycnal mixing within Cascadia Basin provide about 2-3% of the total required global input to the upward branch of the global thermohaline circulation.

    The California Continental Borderland's present configuration dates from about 4 to 5 X 10 6 years Before Present (B.P.) and is the most recent of several configurations of the southern California margin that have evolved after the North America Plate over-rode the East Pacific Rise about 30 X 10 6 years ago. The present morphology is a series of two to three northwest-southeast trending rows of depressions separated by banks and insular ridges. Two inner basins, Santa Monica and San Pedro, have been the site for the Department of Energy-funded California Basin Study (CaBS) Santa Monica and San Pedro Basins contain post-Miocene sediment thicknesses of about 2.5 and 1.5 km respectively. During the Holocene (past 10,000 years) about 10-12 m have accumulated. The sediment entered the basin by one or a combination of processes including particle infall (mainly as bioaggregates) from surface waters, from nepheloid plumes (surface, mid-depths and near-bottom), from turbidity currents, mass movements, and to a very minor degree direct precipitation. In Santa Monica Basin, during the last century, particle infall and nepheloid plume transport have been the most common processes. The former dominates in the central basin floor in water depths from 900 to 945 m. where a characteristic silt-clay with a typical mean diameter of about 0.006 mm, phi standard deviation

Propõe-se aqui também que não apenas a interdisciplinaridade, bastante praticada hoje, mas também relações transversais ao próprio campo da antropologia são desejáveis — isto é, que os antropólogos “urbanos” levem em conta o que dizem os etnólogos, que estes dialoguem com os estudos de gênero etc. De todo modo, a bibliografia incluída ainda é, e continuará a sê-lo por um bom tempo, leitura necessária para pesquisadores que se interessem pela história da antropologia.

    Full Text Available Este artigo critica a concepção predominante, representacionista-neurofisicalista sobre a percepção sensorial. Introduz a noção de "campo-experiência" na tentativa de tratamento ontológico dos dados fenomenológicos da experiência. A idéia geral é que a experiência visual, por exemplo, seria ontologicamente algo assim como um campo-experiência de intencionalidade visual, que se estende por sobre e entre o sistema nervoso central do sujeito da experiência e o objeto distai da visão. 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. Algumas conseqüências específicas do macrorrealismo fenomenológico são apresentadas.

  3. Helping enhances productivity in campo flicker ( Colaptes campestris) cooperative groups

    Dias, Raphael Igor; Webster, Michael S.; Macedo, Regina H.

    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.

    El proyecto de instrumentación de mayor importancia que ha tenido el Instituto de Astrofisica de Canarias en los últimos afios ha sido el diseflo y construcción del te1escopio IAC8O. 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.

    Basins containing the early Mesozoic Newark Supergroup formed during the incipient rifting of Pangaea. The basins are characterized by the following: (1) The border fault systems (BFS) represent reactivated older faults. (2) A regionally persistent northwest-southeast to west-northeast-east-southeast extension direction reactivated northeast- to north-striking structures as predominantly normal dip-slip faults. (3) The half-grabens are lozenge-shaped basins in which subsidence-fault slip was greatest at or near the center of the BFS and decreased to zero toward either end. (4) Transverse folds in the hanging walls immediately adjacent to the BFS formed as a result of higher-frequency variations in subsidence. (5) Subsidence also decreased in a direction perpendicular to the BFS. (6) Intrabasinal faults are overwhelmingly synthetic and predominantly post-depositional. (7) Younger strata progressively onlap prerift rocks of the hanging wall block; this indicates that the basins grew both in width and length as they filled. (8) In all basins initial sedimentation was fluvial, reflecting an oversupply of sediment with respect to basin capacity. (9) Sediments were derived largely from the hanging wall block, which sloped toward the basin, and from streams that entered the basin axially; a direct footwall source was minor, owing to footwall uplift. (10) In strike-slip-dominated basins, subsidence was considerably less than in dip-slip basins, and mosaics of strike- and dip-slip faults are common.

  12. Origin and evolution of the Seattle Fault and Seattle Basin, Washington

    Analysis of seismic reflection data reveals that the Seattle basin (Washington) is markedly asymmetric and consists of ~9-10 km of Eocene and younger deposits. The basin began as a discrete geologic element in the late Eocene (~40 Ma), the result of a reorganization in regional fault geometry and kinematics. In this reorganization, dextral offset on the Puget fault southeast of Seattle stepped eastward, and the Seattle fault began as a restraining transfer zone. North-vergent reverse or thrust faulting on the Seattle fault forced flexural subsidence in the Seattle basin to the north. Offset on the Seattle fault and subsidence of the Seattle basin have continued to the present. -Authors

    The Southeast Asian region had been subjected to a drastic reduction in air quality from the biomass burnings that occurred in 2013 and 2015. The smoke from the biomass burnings covered the entire region including Brunei, Indonesia, Malaysia, Singapore and Thailand, with haze particulate matter (PM) reducing the air quality to hazardous levels. Here we report a comprehensive size-composition-morphology characterization of the PM collected from an urban site in Singapore during the two haze events. The two haze events were a result of biomass burning and occurred in two different geographical source regions. We show the similarities and variations of particle size distribution during hazy and clear days during the two haze events. Sub-micron particles (method is used to determine the fractal dimensions of the PM, and the dimensionality varied for every classification from 1.79 to 1.88. We also report the complexities of particles and inconsistencies in the existing approaches to understand them.

    Effective conservation of freshwater biodiversity requires spatially explicit investigations of how dams and hydroclimatic alterations among climate regions may interact to drive species to extinction. We investigated how dams and hydroclimatic alterations interact with species ecological and life history traits to influence past extirpation probabilities of native freshwater fishes in the Upper and Lower Colorado River (CR), Alabama-Coosa-Tallapoosa (ACT), and Apalachicola-Chattahoochee-Flint (ACF) basins. Using long-term discharge data for continuously gaged streams and rivers, we quantified streamflow anomalies (i.e., departure "expected" streamflow) at the sub-basin scale over the past half-century. Next, we related extirpation probabilities of native fishes in both regions to streamflow anomalies, river basin characteristics, species traits, and non-native species richness using binomial logistic regression. Sub-basin extirpations in the Southwest (n = 95 Upper CR, n = 130 Lower CR) were highest in lowland mainstem rivers impacted by large dams and in desert springs. Dampened flow seasonality, increased longevity (i.e., delayed reproduction), and decreased fish egg sizes (i.e., lower parental care) were related to elevated fish extirpation probability in the Southwest. Sub-basin extirpations in the Southeast (ACT n = 46, ACF n = 22) were most prevalent in upland rivers, with flow dependency, greater age and length at maturity, isolation by dams, and greater distance upstream. Our results confirm that dams are an overriding driver of native fish species losses, irrespective of basin-wide differences in native or non-native species richness. Dams and hydrologic alterations interact with species traits to influence community disassembly, and very high extirpation risks in the Southeast are due to interactions between high dam density and species restricted ranges. Given global surges in dam building and retrofitting, increased extirpation risks should be

    Phylogenic evidence suggests that the strain of Zika virus causing an unprecedented outbreak of disease in the Americas had its origin in Southeast Asia, where reports of isolated cases of Zika virus infection have occurred since 2010. Why there has been no large outbreak of Zika infection in Southeast Asia remains unclear and whether such an outbreak will occur in the future is a question of significant concern. This review looks at Zika virus from a Southeast Asian perspective and highlights some of the possible scenarios with regards to Zika virus in this part of the world as well as highlighting some of the research questions that need to be urgently addressed.

    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.

  14. Drug problem in southeast and southwest Asia.

    2004-10-01

    In 2002, the drug problem in Southeast and Southwest Asia was serious, particularly in the production of opium and heroin in Afghanistan, Myanmar, and Laos, the three largest producers of illicit opium in the world. The increasing illicit manufacture of ATS, particularly methamphetamine, in Southeast Asia, mainly in China and Myanmar, was also a major concern. Some reports indicated that ephedrine, used for illicitly producing methamphetamine in Southeast Asia, is diverted and smuggled out of China and India, whereas caffeine, the adulterant used for producing methamphetamine tablets, is mainly smuggled into Myanmar through its border with Thailand. Seizure data showed a dramatic increase in trafficking in MDMA through Southeast Asia. In terms of the drug epidemic, in 2002, cannabis remained overall the main drug of abuse in all of the countries of Southeast and Southwest Asia. Opiates, mainly opium and heroin, were also the drugs of choice except in Thailand, where opiate abuse declined, but ATS was the main drug of abuse due to its low cost and availability. A significant increase in ATS abuse, amphetamine, methamphetamine, and MDMA among the youth who smoked, sniffed, and inhaled them was reported in Cambodia, China, Indonesia, Laos, Myanmar, the Philippines, and Thailand. Injecting drug use among opiate abusers has been identified as the prime cause of the rapid spread of HIV/AIDS in Southeast and Southwest Asia.

  15. SOUTHEAST ASIA: HISTORY, MODERNITY, AND RELIGIOUS CHANGE

    2015-11-01

    Full Text Available Southeast Asia or Southeastern Asia, with more than six hundred million populations, is home to millions of Buddhists, Muslims, Confucians, Protestants, Catholics, and now Pentecostals, as well as many followers of local religions and spiritual beliefs. Notwithstanding its great historical, political, cultural legacies, however, the region has long been neglected as a site for religious studies in the Western academia. Aiming at filling the gap in Asian and religious studies as well as exploring the richness of Southeast Asian cultures, this article discusses the dynamics, diversity, and complexity of Southeast Asian societies in their response to the region’s richly political, cultural, and religious traditions spanning from pre-modern era to modern one. The article also examines the “integrative revolutions” that shaped and reshaped warfare, state organization and economics of Southeast Asia, particularly in the pre-European colonial era. In addition, the work discusses the wave of Islamization, particularly since the nineteenth century, as well as the upsurge of religious resurgence that shift the nature of religiosity and the formation of religious groupings in the area. The advent of Islam, with some interventions of political regimes, had been an important cause for the decline of Hindu-Buddhist traditions in some areas of Southeast Asia, especially Indonesia, the coming of Pentecostalism has challenged the well-established mainstream Protestantism and Catholicism, especially in Indonesia and the Philippines.

    Southeast Asian seas span the largest archipelago in the global ocean and provide a complex oceanic pathway connecting the Pacific and Indian oceans. The Southeast Asian sea regional sea level trends are some of the highest observed in the modern satellite altimeter record that now spans almost 2 decades. Initial comparisons of global sea level reconstructions find that 17-year sea level trends over the past 60 years exhibit good agreement with decadal variability associated with the Pacific Decadal Oscillation and related fluctuations of trade winds in the region. The Southeast Asian sea region exhibits sea level trends that vary dramatically over the studied time period. This historical variation suggests that the strong regional sea level trends observed during the modern satellite altimeter record will abate as trade winds fluctuate on decadal and longer timescales. Furthermore, after removing the contribution of the Pacific Decadal Oscillation (PDO) to sea level trends in the past 20 years, the rate of sea level rise is greatly reduced in the Southeast Asian sea region. As a result of the influence of the PDO, the Southeast Asian sea regional sea level trends during the 2010s and 2020s are likely to be less than the global mean sea level (GMSL) trend if the observed oscillations in wind forcing and sea level persist. Nevertheless, long-term sea level trends in the Southeast Asian seas will continue to be affected by GMSL rise occurring now and in the future.

    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.

    The Southeast Regional Carbon Sequestration Partnership's (SECARB) Phase I program focused on promoting the development of a framework and infrastructure necessary for the validation and commercial deployment of carbon sequestration technologies. The SECARB program, and its subsequent phases, directly support the Global Climate Change Initiative's goal of reducing greenhouse gas intensity by 18 percent by the year 2012. Work during the project's two-year period was conducted within a ''Task Responsibility Matrix''. The SECARB team was successful in accomplishing its tasks to define the geographic boundaries of the region; characterize the region; identify and address issues for technology deployment; develop public involvement and education mechanisms; identify the most promising capture, sequestration, and transport options; and prepare action plans for implementation and technology validation activity. Milestones accomplished during Phase I of the project are listed below: (1) Completed preliminary identification of geographic boundaries for the study (FY04, Quarter 1); (2) Completed initial inventory of major sources and sinks for the region (FY04, Quarter 2); (3) Completed initial development of plans for GIS (FY04, Quarter 3); (4) Completed preliminary action plan and assessment for overcoming public perception issues (FY04, Quarter 4); (5) Assessed safety, regulatory and permitting issues (FY05, Quarter 1); (6) Finalized inventory of major sources/sinks and refined GIS algorithms (FY05, Quarter 2); (7) Refined public involvement and education mechanisms in support of technology development options (FY05, Quarter 3); and (8) Identified the most promising capture, sequestration and transport options and prepared action plans (FY05, Quarter 4).

    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)

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

  8. China, Southeast Asia, and the United States

    Full Text Available Southeast Asia has historically been a meeting point between East Asia and South Asia before Western colonialism opened the region to the West and to the winds of global modernization. Since Japan’s coercive decolonization during the Second World War, the dominant outside influences have come from the United States and from the People’s Republic of China. The post-Cold War era began with a withdrawal of both China’s and US power projection from Southeast Asia, facilitating the configuration of a triangular ménage à trios, with ASEAN expanding to include all of Southeast Asia and introducing a number of extended forums intended to socialize the rest of East Asia into the ASEAN way. The “rise of China” occurred within this friendly context, though beginning around 2010 its strategic implications began to appear more problematic with the mounting dispute over the issue of the South China Sea.

    2009-12-01

    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.

    2013-01-01

    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.

Este campo quiral representa un tipo novedoso de campo que no puede ser identificado con alguno de los campos electromagnéticos conocidos.

    In 2010 the Southeast Energy Efficiency Alliance (SEEA) received a $20 million Energy Efficiency and Conservation Block Grant (EECBG) under the U.S. Department of Energy’s Better Building Neighborhood Program (BBNP). This grant, funded by the American Recovery and Reinvestment Act, also included sub-grantees in 13 communities across the Southeast, known as the Southeast Consortium. The objective of this project was to establish a framework for energy efficiency retrofit programs to create models for replication across the Southeast and beyond. To achieve this goal, SEEA and its project partners focused on establishing infrastructure to develop and sustain the energy efficiency market in specific localities across the southeast. Activities included implementing minimum training standards and credentials for marketplace suppliers, educating and engaging homeowners on the benefits of energy efficiency through strategic marketing and outreach and addressing real or perceived financial barriers to investments in whole-home energy efficiency through a variety of financing mechanisms. The anticipated outcome of these activities would be best practice models for program design, marketing, financing, data collection and evaluation as well as increased market demand for energy efficiency retrofits and products. The Southeast Consortium’s programmatic impacts along with the impacts of the other BBNP grantees would further the progress towards the overall goal of energy efficiency market transformation. As the primary grantee SEEA served as the overall program administrator and provided common resources to the 13 Southeast Consortium sub-grantees including contracted services for contractor training, quality assurance testing, data collection, reporting and compliance. Sub-grantee programs were located in cities across eight states including Alabama, Florida, Georgia, Louisiana, North Carolina, South Carolina, Tennessee, Virginia and the U.S. Virgin Islands.

    2016-09-01

    The Sundaland continental promontory, as the core of Southeast Asia, is one of the lowest lying continental regions, with half of the continental area presently inundated by a shallow sea. The role of mantle convection in driving long-wavelength topography and vertical motion of the lithosphere in this region has often been ignored when interpreting regional stratigraphy, including a widespread Late Cretaceous-Eocene unconformity, despite a consensus that Southeast Asia is presently situated over a large-amplitude dynamic topography low resulting from long-term post-Pangea subduction. We use forward numerical models to link mantle flow with surface tectonics and compare predicted trends of dynamic topography with eustasy and regional paleogeography to determine the influence of mantle convection on regional basin histories. A Late Cretaceous collision of Gondwana-derived terranes with Sundaland choked the active margin, leading to slab breakoff and a ˜10-15 Myr-long subduction hiatus. A subduction hiatus likely resulted in several hundred meters of dynamic uplift and emergence of Sundaland between ˜80 and 60 Ma and may explain the absence of a Late Cretaceous-Eocene sedimentary record. Renewed subduction from ˜60 Ma reinitiated dynamic subsidence of Sundaland, leading to submergence from ˜40 Ma despite falling long-term global sea levels. Our results highlight a complete "down-up-down" dynamic topography cycle experienced by Sundaland, with transient dynamic topography manifesting as a major regional unconformity in sedimentary basins.

  19. 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

    Full Text Available A disjunct distribution pattern between the extrazonal formations of the campos rupestres (rocky grasslands in the Espinhaço mountain range and the restingas (coastal strand vegetation in Brazil has been proposed repeatedly for several flowering-plant species. In order to validate this distribution pattern, available data from the literature and major herbaria were compiled and evaluated. 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%.

    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.

    The occurrence of high concentrations of arsenic in the groundwater of the Southeast Asia region has received much attention in the past decade. This study presents an overview of the arsenic contamination problems in Vietnam, Cambodia, Lao People's Democratic Republic and Thailand. Most groundwater used as a source of drinking water in rural areas has been found to be contaminated with arsenic exceeding the WHO drinking water guideline of 10 μg·L(-1). With the exception of Thailand, groundwater was found to be contaminated with naturally occurring arsenic in the region. Interestingly, high arsenic concentrations (> 10 μg·L(-1)) were generally found in the floodplain areas located along the Mekong River. The source of elevated arsenic concentrations in groundwater is thought to be the release of arsenic from river sediments under highly reducing conditions. In Thailand, arsenic has never been found naturally in groundwater, but originates from tin mining activities. More than 10 million residents in Southeast Asia are estimated to be at risk from consuming arsenic-contaminated groundwater. In Southeast Asia, groundwater has been found to be a significant source of daily inorganic arsenic intake in humans. A positive correlation between groundwater arsenic concentration and arsenic concentration in human hair has been observed in Cambodia and Vietnam. A substantial knowledge gap exists between the epidemiology of arsenicosis and its impact on human health. More collaborative studies particularly on the scope of public health and its epidemiology are needed to conduct to fulfill the knowledge gaps of As as well as to enhance the operational responses to As issue in Southeast Asian countries.

    Full Text Available The Fushan Depression is a half-graben rifted sub-basin located in the southeast of the Beibuwan Basin, South China Sea. The Paleogene Liushagang sequence is the main hydrocarbon-bearing stratigraphic unit in the sub-basin. Using three-dimensional (3-D seismic data and logging data over the sub-basin, we analyzed structural styles and sedimentary characteristics of the Liushagang sequence. Five types of structural styles were defined: ancient horst, traditional slope, flexure slope-break, faulted slope-break and multiple-stage faults slope, and interpretations for positions, background and development formations of each structural style were discussed. Structural framework across the sub-basin reveals that the most remarkable tectonic setting is represented by the central transfer zone (CTZ which divides the sub-basin into two independent depressions, and two kinds of sequence architectures are summarized: (i the western multi-stage faults slope; (ii the eastern flexure slope break belt. Combined with regional stress field of the Fushan Depression, we got plane combinations of the faults, and finally built up plan distribution maps of structural system for main sequence. Also, we discussed the controlling factors mainly focused on subsidence history and background tectonic activities such as volcanic activity and earthquakes. The analysis of structural styles and tectonic evolution provides strong theoretical support for future prospecting in the Fushan sub-basin and other similar rifted basins of the Beibuwan Basin in South China Sea.

    The risks and opportunities in the rapidly developing markets in Southeast Asia, China in particular, were discussed. It was asserted that no other region in the world can match the long-term market opportunities that China and Southeast Asia promise. The forces driving the economic development in Southeast Asia were described, including the great potential the region holds for the petrochemical industry. Graphs showing total polyethylene production vs. demand for year 2005 were included as illustrative examples. By 2005, China is projected to be importing almost one-half of the products it consumes. Every country with excess capacity will supply China with polyethylene. The political uncertainties that makes doing business in the region a high risk undertaking were reviewed, along with other risks relevant to the petrochemical industry such as (1) high capital costs, (2) over-building to the point that there is more supply than demand for the product, (3) low-cost producers may drive down prices to maintain market share, and (4) the uncertain nature of projections regarding economic growth and (5) inflated estimates of demand for petrochemicals. 1 tab., 4 figs

    2009-01-01

    The Johnson Creek basin is an important resource in the Portland, Oregon, metropolitan area. Johnson Creek forms a wildlife and recreational corridor through densely populated areas of the cities of Milwaukie, Portland, and Gresham, and rural and agricultural areas of Multnomah and Clackamas Counties. The basin has changed as a result of agricultural and urban development, stream channelization, and construction of roads, drains, and other features characteristic of human occupation. Flooding of Johnson Creek is a concern for the public and for water management officials. The interaction of the groundwater and surface-water systems in the Johnson Creek basin also is important. The occurrence of flooding from high groundwater discharge and from a rising water table prompted this study. As the Portland metropolitan area continues to grow, human-induced effects on streams in the Johnson Creek basin will continue. This report provides information on the groundwater and surface-water systems over a range of hydrologic conditions, as well as the interaction these of systems, and will aid in management of water resources in the area. High and low flows of Crystal Springs Creek, a tributary to Johnson Creek, were explained by streamflow and groundwater levels collected for this study, and results from previous studies. High flows of Crystal Springs Creek began in summer 1996, and did not diminish until 2000. Low streamflow of Crystal Springs Creek occurred in 2005. Flow of Crystal Springs Creek related to water-level fluctuations in a nearby well, enabling prediction of streamflow based on groundwater level. Holgate Lake is an ephemeral lake in Southeast Portland that has inundated residential areas several times since the 1940s. The water-surface elevation of the lake closely tracked the elevation of the water table in a nearby well, indicating that the occurrence of the lake is an expression of the water table.

    In planning to develop the vast potential of the Mekong river in Southeast Asia, a number of institutional aspects need to be addressed, and the sometimes diverging interests of the riparian countries need to be carefully balanced. The Mekong river is an extremely valuable natural resource: its potential for irrigation, hydropower, navigation, fisheries and related development is more than adequate to raise significantly the standards of living of the people of the lower Mekong basin and in the riparian countries outside the river's catchment area. The Mekong's catchment area of 795 000 km[sup 2] encompasses parts of China and Myanmar, the whole of Laos and Cambodia, one third of Thailand and one fifth of Viet Nam. The population of the Mekong basin is around 100 million, about half of whom live in the lower basin. It could be said that these impoverished inhabitants of the basin depend significantly on the Mekong for an improvement in their livelihood, and this places a heavy responsibility on those involved in developing its water resources. The Mekong Committee, since its establishment in 1957 and in its present interim status since 1977, is dedicated to the co-ordinated development of the basin's resources, on the basis of reasonable and equitable sharing between the riparian states as stated in the Committee's declaration of principles. With the establishment of the Mekon Committee, serious efforts have been made aimed at rational management of water resources use. (author).

    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

  16. Spatial variations of effective elastic thickness of the Lithosphere in the Southeast Asia regions

    The effective elastic thickness Te corresponds to the thickness of an idealized elastic beam that would bend similarly to the actual lithosphere under the same applied loads, and could provide important insight into rheology and state of stress. Thus, it is helpful to improve our understanding of the relationship between tectonic styles, distribution of earthquakes and lithospheric rheology in various tectonic settings. The Southeast Asia, located in the southeastern part of the Eurasian Plate, comprises a complex collage of continental fragments, volcanic arcs, and suture zones and marginal oceanic basins, and is surrounded by tectonically active margins which exhibit intense seismicity and volcanism. The Cenozoic southeastward extrusion of the rigid Indochina Block due to the Indo-Asian collision resulted in the drastic surface deformation in the western area. Therefore, a high resolution spatial variation map of Te might be a useful tool for the complex Southeast Asia area to examine the relationships between surface deformation, earthquakes, lithospheric structure and mantle dynamics. In this study, we present a high-resolution map of spatial variations of Te in the Southeast Asia area using the wavelet method, which convolves a range of scaled wavelets with the two data sets of Bouguer gravity anomaly and topography. The topography and bathymetry grid data was extracted from the GEBCO_08 Grid of GEBCO digital atlas. The pattern of Te variations agrees well with the tectonic provinces in the study area. On the whole, low lithosphere strength characterizes the oceanic basins, such as the South China Sea, the Banda sea area, the Celebes Sea, the Sulu Sea and the Andaman Sea. Unlike the oceanic basins, the continental fragments show a complex pattern of Te variations. The Khorat plateau and its adjacent area show strong lithosphere characteristics with a Te range of 20-50 km, suggesting that the Khorat plateau is the strong core of the Indochina Block. The West

  18. Dengue in the Americas and Southeast Asia: do they differ?

    2006-12-01

    The populations of Southeast Asia (SE Asia) and tropical America are similar, and all four dengue viruses of Asian origin are endemic in both regions. Yet, during comparable 5-year periods, SE Asia experienced 1.16 million cases of dengue hemorrhagic fever (DHF), principally in children, whereas in the Americas there were 2.8 million dengue fever (DF) cases, principally in adults, and only 65,000 DHF cases. This review aims to explain these regional differences. In SE Asia, World War II amplified Aedes aegypti populations and the spread of dengue viruses. In the Americas, efforts to eradicate A. aegypti in the 1940s and 1950s contained dengue epidemics mainly to the Caribbean Basin. Cuba escaped infections with the American genotype dengue-2 and an Asian dengue-3 endemic in the 1960s and 1970s. Successive infections with dengue-1 and an Asian genotype dengue-2 resulted in the 1981 DHF epidemic. When this dengue-2 virus was introduced in other Caribbean countries, it encountered populations highly immune to the American genotype dengue-2. During the 1980s and 1990s, rapidly expanding populations of A. aegypti in Brazil permitted successive epidemics of dengue-1, -2, and -3. These exposures, however, resulted mainly in DF, with surprisingly few cases of DHF. The absence of high rates of severe dengue disease in Brazil, as elsewhere in the Americas, may be partly explained by the widespread prevalence of human dengue resistance genes. Understanding the nature and distribution of these genes holds promise for containing severe dengue. Future research on dengue infections should emphasize population-based designs.

  20. Tropical Indian Ocean Variability Driving Southeast Australian Droughts

    Variability in the tropical Indian Ocean has widespread effects on rainfall in surrounding countries, including East Africa, India and Indonesia. The leading mode of tropical Indian Ocean variability, the Indian Ocean Dipole (IOD), is a coupled ocean-atmosphere mode characterized by sea surface temperature (SST) anomalies of opposite sign in the east and west of the basin with an associated large-scale atmospheric re-organisation. Earlier work has often focused on the positive phase of the IOD. However, we show here that the negative IOD phase is an important driver of regional rainfall variability and multi-year droughts. For southeastern Australia, we show that it is actually a lack of the negative IOD phase, rather than the positive IOD phase or Pacific variability, that provides the most robust explanation for recent drought conditions. Since 1995, a large region of Australia has been gripped by the most severe drought in living memory, the so-called "Big Dry". The ramifications for affected regions are dire, with acute water shortages for rural and metropolitan areas, record agricultural losses, the drying-out of two of Australia's major river systems and far-reaching ecosystem damage. Yet the drought's origins have remained elusive. For Southeast Australia, we show that the "Big Dry" and other iconic 20th Century droughts, including the Federation Drought (1895-1902) and World War II drought (1937-1945), are driven by tropical Indian Ocean variability, not Pacific Ocean conditions as traditionally assumed. Specifically, a conspicuous absence of characteristic Indian Ocean temperature conditions that are conducive to enhanced tropical moisture transport has deprived southeastern Australia of its normal rainfall quota. In the case of the "Big Dry", its unprecedented intensity is also related to recent above-average temperatures. Implications of recent non-uniform warming trends in the Indian Ocean and how that might affect ocean characteristics and climate in

  5. Variation in forearc basin development along the Sunda Arc, Indonesia

    Science.gov (United States)

    van der Werff, W.

    The present forearc basin configuration along the Sunda Arc initially appears to have been controlled by extension and differential subsidence of basement blocks in response to the late Eocene collision of India with Asia. The late Oligocene increase in convergence between the South-east Asian and Indian Plates associated with a new pulse of subduction, resulted in basement uplift and the formation of a regional unconformity that can be recognized along the entire Sunda Arc. From the early to late Miocene, the Sumba and Savu forearc sectors along the eastern Sunda Arc may have been characterized by forearc extension. Submarine fan deposition on the arcward side of the evolving accretionary prism represents the first phase in forearc basin deposition. These fans were subsequently covered by basin and slope sediments derived from the evolving magmatic arc. Structural response to increased late Miocene compression varied along strike of the Sunda Arc. North of Bali, Lombok and Sumbawa, the incipient collision between Australia and the western Banda Arc caused back-arc thrusting and basin inversion. Towards the south of Java, an increase in both the size of the accretionary prism and convergence rates resulted in uplift and large scale folding of the outer forearc basin strata. Along the west coast of Sumatra, increased compression resulted in uplift along the inner side of the forearc along older transcurrent faults. Uplift of West Sumatra was followed by the deposition of a westward prograding sequence of terrigenous sediments that resulted in the development of a broad shelf. Initial forearc basin subsidence relates to the age of the subducting oceanic lithosphere, on top of which the basin is situated. Along the western Sunda Arc, both fexural loading of the evolving accretionary prism, and across arc strike-slip faulting represent additional factors that result in forearc subsidence.

    In order to discuss the subject of occupational medicine in the next century, changes in the present demographic profile and work activity must be considered first. Only then can the challenges be identified, and appropriate strategies be formulated to respond to them. In the diverse countries of South-East Asia, improved health and work conditions, the advent of new technology, a redistribution of work activity, and an ageing workforce can be expected. Two other factors that have specific impact in the region are the recent financial crisis and the occurrence of an international environmental haze from forest fires. The various countries in South-East Asia, which are in different stages of development, and have different problems and priorities, will respond differently to the demands for occupational health. It is likely that there will be a shift in the focus of current health care activities towards specific work sectors, the recognition of new hazards at work, the identification of newly emerging work related diseases, and an increase in health promotion in the workplace. Hopefully, there will be improved training of health professionals to ensure that there are adequate numbers and that they are well prepared to face these changes. Responsive, appropriate and well enforced labour legislation to protect the health of all workers, and international cooperation in occupational and environmental health are also required. As global and regional economic conditions continue to remain unstable and the impact of the crisis further takes its course, the final effect on occupational health in South-East Asia remains to be seen.

    With an understudied amphibian fauna, the highest deforestation rate on the planet and high harvesting pressures, Southeast Asian amphibians are facing a conservation crisis. Owing to the overriding threat of habitat loss, the most critical conservation action required is the identification and strict protection of habitat assessed as having high amphibian species diversity and/or representing distinctive regional amphibian faunas. Long-term population monitoring, enhanced survey efforts, collection of basic biological and ecological information, continued taxonomic research and evaluation of the impact of commercial trade for food, medicine and pets are also needed. Strong involvement of regional stakeholders, students and professionals is essential to accomplish these actions.

    1989-01-01

    Ruminant production in Southeast Asia is not a very large industry but has the potential for expansion because there is an adequate feed supply of conventional and non-conventional types. Grazing ruminants on permanent pasture and wasteland is the most common method of animal management practised by small scale farmers. Programmes to improve pasture in the grazing resources should be implemented. Introducing ruminants into plantations is a viable proposition. Further increases in ruminant productivity can be attained if the technology on utilizing crop residues and by-products can be transferred to farmers and applied more widely.

    A 3000 m thick Gondwana lithic fill consisting of multifacies associations were preserved in a NW-SE oriented intracratonic Chintalapudi sub-basin set across the Eastern Chat Complex (EGC). Sedimentation commenced with the deposition of diamictite-rhythmite sequence of the Talchir Formation in glacio-lacustrine environment. The succeeding sandstone-coal cyclothems of the Barakar Formation were formed in fluvial-coal swamps complex. The fluvial streams flowed across the EGC, originating somewhere in the southeast beyond the East Coast of India. Phase wise upliftment of the EGC during Mesozoic imparted changes to the Permian intercontinental drainage system which started supplying increased amount of detritus to the basin. Basin marginal faults were first formed at the beginning of Triassic. Alluvial fans originated in the east and southeast and northwesterly flowing braided streams deposited the conglomerate sandstone sequence of the Kamthi Formation. The Early Jurassic uplift of the Mailaram high in the north imparted westerly shift to the braided rivers during the Kota sedimentation. Due to prominence of Kamavarapukota ridge in the south by Early Cretaceous, the drainage pattern became centripetal and short-lived high sinuous rivers debouched into the basin. The silting up of the Chintalapudi sub-basin with the sandstone-claystone sequence of the Gangapur Formation marks the culmination of the Gondwana sedimentation, perhaps, coinciding with the breakup of India from the Gondwanaland.

We prove that Einstein's equations for these fields have the same form as the stress-energy tensor of electromagnetism if the total external current . 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)

    Full Text Available A noção de economista, longe de simples e evidente, é objeto de numerosas lutas de definição. 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. Demand management implementation in Southeast Asia

    Energy Technology Data Exchange (ETDEWEB)

    1995-12-31

    The need to apply transportation system management, to developing countries is urgent. Attempts to alleviate severe traffic congestion in their metropolises have so far failed to provide adequate solutions. The countries are faced with many difficulties because of the lack of sufficient financial resources together with their complex internal administrative and political problems. They are incapable of providing sufficient road space to cope with the escalating demand in private automobiles. This has led to excessive delays in urban traveling, environmental pollution problems, decline of road-based public transit services and deterioration of the quality of life in these metropolises. Demand management, in use for decades in the Western world, has also been recognized in Singapore`s famous area licensing scheme (ALS) making other Southeast Asian Metropolises aware of its advantages as an alternative in solving their chaotic traffic problems. However, realization is far different from implementation and still many metropolises are not able to apply the technique. Singapore and Thailand, two leaders among many other Southeast Asian regions in economics, tourism, trade and industry handle their problems far differently, especially the traffic congestion problem. While a number of demand management schemes have been implemented successfully in Singapore since 1975, Bangkok is still struggling to implement such measures to alleviate severe traffic congestion problems. This article intends to high light the successful practices and unsuccessful attempts of demand management techniques applied in Singapore and Bangkok.

  3. Natural gas pricing policies in Southeast Asia

    International Nuclear Information System (INIS)

    Pacudan, R.B.

    1998-01-01

    The very dynamic economies of Southeast Asia have recently been experiencing a rapid increase in energy demand. Parallel to this development, there has been an increase in the utilization of indigenous natural gas resources. This article reviews gas-pricing policies in the region, which partly explain the rise in gas utilization. Although diverse, energy pricing policies in Southeast Asia address the common objective of enhancing domestic gas production and utilization. The article concludes that a more rational gas-pricing policy framework is emerging in the region. In global terms, gas pricing in the region tends to converge in a market-related framework, despite the many different pricing objectives of individual countries, and the predominance of non-economic pricing objectives in certain countries (especially gas-rich nations). Specifically, governments have been flexible enough to follow global trends and initiate changes in contractual agreements (pricing and profit-sharing), giving oil companies more favourable terms, and encouraging continued private investment in gas development. At the same time, promotional pricing has also been used to increase utilization of gas, through set prices and adjusted taxes achieving a lower price level compared to substitute fuels. For an efficient gas-pricing mechanism, refinements in the pricing framework should be undertaken, as demand for gas approaches existing and/or forecast production capacities. (author)

    Raykova, R.B.; Panza, G.F.

    2005-11-01

    A set of shear-wave velocity models of the lithosphere-asthenosphere system in the southeast Carpathians is determined by the non-linear inversion of surface wave group velocity data, obtained from a tomographic analysis. The local dispersion curves are assembled for the period range 7 s - 150 s, combining regional group velocity measurements and published global Rayleigh wave dispersion data. The lithosphere-asthenosphere velocity structure is reliably reconstructed to depths of about 250 km. The thickness of the lithosphere in the region varies from about 120 km to 250 km and the depth of the asthenosphere between 150 km and 250 km. Mantle seismicity concentrates where the high velocity lid is detected just below the Moho. The obtained results are in agreement with recent seismic refraction, receiver function, and travel time P-wave tomography investigations in the region. The similarity among the results obtained from different kinds of structural investigations (including the present work) highlights some new features of the lithosphere-asthenosphere system in southeast Carpathians, as the relatively thin crust under Transylvania basin and Vrancea zone.

    the Axial Ranges at ca 1.75 Ma, resulting in 5100-5700 m of differential subsidence across the fault system. Sedimentation has propagated south- to southeast-ward over the last 4 Myrs at the tip of successive back-arc graben, volcanic arcs and the associated thermally uplifted parts of the North Island, following the southward migration of the Hikurangi subduction margin. Subsidence occurred by mantle flow-driven flexure, the result of active down-drag of the lithosphere by locking of the Hikurangi subduction interface and sediment loading. The WB is considered to be a proto-back-arc basin that represents the intermediate stage of evolution of an epicratonic shelf platform, impacted by active margin processes.

    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.

    Full Text Available É comum hoje em dia a inserção do idoso brasileiro no rol da prática de atividades físicas. No entanto, até o segundo quartel do século XX, acreditava-se que a prática de atividade física sistemática poderia ser nociva ou mesmo antecipar a morte. Este estudo busca analisar e descrever como surgiu o campo da atividade física para idosos no Brasil. Metodologicamente utilizamos uma pesquisa bibliográfica aliada à Teoria do Campo do sociólogo Pierre Bourdieu (1983, que possibilitou a analogia entre o campo internacional do idoso, que se mostrou precursor, e o campo nacional. Tal relação desenvolveu um novo habitus, que transformou o medo em confiança, a dúvida em certeza, o sedentarismo em dinamismo, a eminência da morte em ampliação da vida, culminando no arquétipo dos “novos velhos” brasileiros.

    The Mosolotsane Formation (Lebung Group, Karoo Supergroup) in the Kalahari Karoo Basin of Botswana is a scantly exposed, terrestrial red bed succession which is lithologically correlated with the Late Triassic to Early Jurassic Molteno and Elliot Formations (Karoo Supergroup) in South Africa. New evidence derived from field observations and borehole data via sedimentary facies analysis allowed the assessment of the facies characteristics, distribution and thickness variation as well as palaeo-current directions and sediment composition, and resulted in the palaeo-environmental reconstruction of this poorly known unit. Our results show that the Mosolotsane Formation was deposited in a relatively low-sinuosity meandering river system that drained in a possibly semi-arid environment. Sandstone petrography revealed mainly quartz-rich arenites that were derived from a continental block provenance dominated by metamorphic and/or igneous rocks. Palaeo-flow measurements indicate reasonably strong, unidirectional current patterns with mean flow directions from southeast and east-southeast to northwest and west-northwest. Regional thickness and facies distributions as well as palaeo-drainage indicators suggest that the main depocenter of the Mosolotsane Formation was in the central part of the Kalahari Karoo Basin. Separated from this main depocenter by a west-northwest - east-southeast trending elevated area, an additional depocenter was situated in the north-northeast part of the basin and probably formed part of the Mid-Zambezi Karoo Basin. In addition, data also suggests that further northeast-southwest trending uplands probably existed in the northwest and east, the latter separating the main Kalahari Karoo depocenter from the Tuli Basin.

  17. Typical synoptic situations and their impacts on the wintertime air pollution in the Guanzhong basin, China

    Directory of Open Access Journals (Sweden)

    N. Bei

    2016-06-01

    Full Text Available Rapid industrialization and urbanization have caused severe air pollution in the Guanzhong basin, northwestern China, with heavy haze events occurring frequently in recent winters. Using the NCEP reanalysis data, the large-scale synoptic situations influencing the Guanzhong basin during wintertime of 2013 are categorized into six types to evaluate the contribution of synoptic situations to the air pollution, including “north-low”, “southwest-trough”, “southeast-high”, “transition”, “southeast-trough”, and “inland-high”. The FLEXPART model has been utilized to demonstrate the corresponding pollutant transport patterns for the typical synoptic situations in the basin. Except for “southwest-trough” and “southeast-high” (defined as favorable synoptic situations, the other four synoptic conditions (defined as unfavorable synoptic situations generally facilitate the accumulation of air pollutants, causing heavy air pollution in the basin. In association with the measurement of PM2.5 (particulate matter with aerodynamic diameter less than 2.5 µm in the basin, the unfavorable synoptic situations correspond to high PM2.5 mass concentrations or poor air quality and vice versa. The same analysis has also been applied to winters of 2008–2012, which shows that the basin was mainly influenced by the unfavorable synoptic situations during wintertime leading to poor air quality. The WRF-CHEM model has further been applied to simulate the selected 6 days representing the typical synoptic situations during the wintertime of 2013, and the results generally show a good agreement between the modeled distributions and variations of PM2.5 and the corresponding synoptic situations, demonstrating reasonable classification for the synoptic situations in the basin. Detailed meteorological conditions, such as temperature inversion, low-level horizontal wind speed, and planetary boundary layer, all contribute to heavy air pollution

    This paper reports that the Asia-Pacific region has gained favor in the increasingly competitive global market for drilling funds and technology. The level of activity in the region contrasts to the U.S., where political, fiscal, and geological conditions have caused an industry-wide depression. Consolidation and restructuring of the oil industry have also affected the Asia-Pacific area, but not as adversely as North America. The shifting focus of most U.S. oil companies to the international sector has increased attention on Southeast Asia. The number of production-sharing contracts and exploration licenses in the region has increased to almost 800, covering an area of 7 million sq km

    Since 1995, a large region of Australia has been gripped by the most severe drought in living memory, the so-called ``Big Dry''. The ramifications for affected regions are dire, with acute water shortages for rural and metropolitan areas, record agricultural losses, the drying-out of two of Australia's major river systems and far-reaching ecosystem damage. Yet the drought's origins have remained elusive. For Southeast Australia, we show here that the ``Big Dry'' and other iconic 20th Century droughts, including the Federation Drought (1895-1902) and World War II drought (1937-1945), are driven by Indian Ocean variability, not Pacific Ocean conditions as traditionally assumed. Specifically, a conspicuous absence of Indian Ocean temperature conditions conducive to enhanced tropical moisture transport has deprived southeastern Australia of its normal rainfall quota. In the case of the ``Big Dry'', its unprecedented intensity is also related to recent higher temperatures.

  20. Permian of Southeast Asia: an overview

    Energy Technology Data Exchange (ETDEWEB)

    Fontaine, H.

    2002-07-01

    Permian rocks are widely distributed throughout Southeast Asia. Because of the tropical-equatorial climate the rocks are commonly deeply weathered and covered by dense vegetation over much of the region. Elsewhere, Permian rocks are well exposed and easy to access, particularly where limestone outcrops have weathered to form spectacular, castellated, tower karst. Many limestone outcrops, containing abundant fusulinaceans, were recognized early on to be of Permian age, but many outcrops without fusulinaceans, erroneously assigned to the Permian, were found subsequently to be of Triassic age, and more careful studies have established the Permian age of rocks of other lithologies. Different depositional environments are represented by the Permian deposits in various parts of the region. Massive limestones, throughout the region represent extensive carbonate platforms; local occurrences of thick bedded cherts indicate deposition in deep marine environments, coal, bauxite and clastic sediments with vertebrate remains in North Vietnam and Laos indicate deposition in a continental environment, and pebbly mudstones in Myanmar, Peninsular Thailand, northwest Malaysia and Sumatra, are considered to have been formed in a glacial environment. Volcanic rocks are not found in northwest Peninsular Malaysia and Peninsular Thailand, but are extensively developed in North Vietnam, Sumatra, the eastern Malay Peninsula and Timor. Fossils are often prolific in Permian sediments, with fusulinaceans, for example, occurring in large numbers in many limestone outcrops. Age-diagnostic fossils demonstrate that the whole of the Permian is represented in different areas of Southeast Asia. Fossil faunal and floral assemblages have been used to establish climatic conditions and environments of deposition, to define distinct crustal blocks and to provide the basis for reconstructing the palaeogeography during Permian times.

  2. Buildings energy efficiency in the Southeast

    Energy Technology Data Exchange (ETDEWEB)

    1993-01-01

    In June 1992, energy service providers from around the Southeastern United States gathered at the Shenandoah Environment and Education Center of Georgia Power Company, to discuss issues related to energy efficiency buildings in the region. The meeting was organized by an ad hoc planning committee under the auspices of the Atlanta Support Office of the DOE. The objectives of the Workshop were to provide a forum for regional energy service providers to discuss matters of mutual concern and to identify issues of particular relevance to the Southeast. What characterizes energy use in the Southeast Most lists would include rapid population growth, high temperatures and humidity, a large air conditioning load on utilities, a relatively clean environment, and regulatory processes that seek to keep energy prices low. There was less unanimity on what are the priority issues. No definitive list of priorities emerged from the workshop. Participants did identify several areas where work should be initiated: networking, training/certification/education, performance of technical measures, and studies of market forces/incentives/barriers. The most frequently mentioned context for these work areas was that of utility programs. Presentations given during the first morning provided attendees an overview of energy use in the region and of building energy conservation programs being implemented both by state agencies and by utilities. These were the base for breakout and plenary sessions in which attendees expressed their views on specific topics. The regional need mentioned most often at the workshop was for networking among energy service providers in the region. In this context, this report itself is a follow up action. Participants also requested a regional directory of energy program resources. DOE agreed to assemble a preliminary directory based upon input from workshop attendees. Because the response was quick and positive, a directory is part of this document.

    Full Text Available Certain reading of postmodernity has diagnosed (actually, offered the end of history, and therefore the end of historical novel, although some of us choose not to bury it but to bring it to live again. 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.

    The comprehensive assessment of climatic and hydrological droughts in terms of their temporal and spatial evolutions is very important for water resources management and social development in the basin scale. To study the spatial and temporal changes of climatic and hydrological droughts and the relationships between them, the SPEI and SDI are adopted to assess the changes and the correlations of climatic and hydrological droughts by selecting the Jialing River basin, China as the research area. The SPEI and SDI at different time scales are assessed both at the entire Jialing River basin and at the regional levels of the three sub basins. The results show that the SPEI and SDI are very suitable for assessing the changes and relationships of climatic and hydrological droughts in large basins. Based on the assessment, for the Jialing River basin, climatic and hydrological droughts have the increasing tendency during recent several decades, and the increasing trend of climatic droughts is significant or extremely significant in the western and northern basin, while hydrological drought has a less significant increasing trend. Additionally, climatic and hydrological droughts tend to increase in the next few years. The results also show that on short time scales, climatic droughts have one or two months lag impact on hydrological droughts in the north-west area of the basin, and have one month lag impact in south-east area of the basin. The assessment of climatic and hydrological droughts based on the SPEI and SDI could be very useful for water resources management and climate change adaptation at large basin scale.

    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.

    The basin of Maider is limited northly by the vast ensemble Oriental Saghro-Ougnate, from the east by the Tafilalet plain, from the west by the oriental Jbel Bani, finally from the south and south-east by the Cretaceous Hamada of Kern-Kem. During last decades, groundwater in the basin of Maider, is confronting degradation in both cases: Quantitative and qualitative, as a result of the drought, the overexploitation and the salinization. The aim of this action research is to understand the current state of water resources in the area of stady. At the end of this work, we can get the following conclusions: the general flow of the ordovician aquifer is always directed from the north to the south-east of the basin by following the principal axes of the wadis:Taghbalt, Hssiya and Fezzou. The recharge of the aquifer is primarily done, either by the underground flow, or by the surface runoff of torrential waters from the upstream of Jbel Saghro. The piezometric anomaly noticed at the level of Ait Saàdane, explained by overexploitation linked to the needs of irrigation water. The physicochemical approach for the Maider basin identifies two essential factors of the salinisation of groundwater: the dissolution of the aquifer which is rich in minerals with high temperature on the one hand, and the decrease of the piezometric surface due to the overexploitation and drought on the other hand.

    Full Text Available DOI: 10.17014/ijog.v8i3.164The SE-NW trending Mountain Front of Central Sumatra Basin is located in the southern part of the basin. The Mountain Front is elongated parallel to the Bukit Barisan Mountain, extending from the Regencies of North Padang Lawas (Gunung Tua in the northwest, Rokan Hulu, Kampar, Kuantan Singingi, and Inderagiri Hulu Regency in the southeast. The Palaeogene sediments also represent potential exploration objectives in Central Sumatra Basin, especially in the mountain front area. Limited detailed Palaeogene sedimentology information cause difficulties in hydrocarbon exploration in this area. Latest age information and attractive sediment characters based on recent geological fieldwork (by chaining method infer Palaeogene sediment potential of the area. The Palaeogene sedimentary rock of the mountain front is elongated from northwest to southeast. Thickness of the sedimentary unit varies between 240 - 900 m. Palynology samples collected recently indicate that the oldest sedimentary unit is Middle Eocene and the youngest one is Late Oligocene. This latest age information will certainly cause significant changes to the existing surface geological map of the mountain front area. Generally, the Palaeogene sediments of the mountain front area are syn-rift sediments. The lower part of the Palaeogene deposit consists of fluvial facies of alluvial fan and braided river facies sediments. The middle part consists of fluvial meandering facies, lacustrine delta facies, and turbidity lacustrine facies sediments. The upper part consists of fluvial braided facies and transitional marine facies sediments. Volcanism in the area is detected from the occurrence of volcanic material as lithic material and spotted bentonite layers in the middle part of the mountain front area. Late rifting phase is indicated by the presence of transitional marine facies in the upper part of the Palaeogene sediments.

  12. Petroleum prospectivity of the Canada Basin, Arctic Ocean

    Grantz, A.; Hart, P.E.

    2011-01-01

    Reconnaissance seismic reflection data indicate that Canada Basin is a remnant of the Amerasia Basin of the Arctic Ocean that lies south of the Alpha-Mendeleev Large Igneous Province, which was constructed on the northern part of the Amerasia Basin between about 127 and 89-75 Ma. Canada Basin is filled with Early Jurassic to Holocene detritus from the Mackenzie River system, which drains the northern third of interior North America, with sizable contributions from Alaska and Northwest Canada. Except for the absence of a salt- and shale-bearing mobile substrate Canada Basin is analogous to the Mississippi Delta and the western Gulf of Mexico. Canada Basin contains about 7 to >14 km of sediment beneath the Mackenzie Prodelta on the southeast, 6 to 7 km of sediment beneath the abyssal plain on the west, and roughly 5 or 6 million cubic km of sediment. About three fourths of the basin fill generates low amplitude seismic reflections, interpreted to represent hemiplegic deposits, and a fourth of the fill generates interbedded lenses to extensive layers of moderate to high amplitude reflections interpreted to represent unconfined turbidite and amalgamated channel deposits. Extrapolation from Arctic Alaska and Northwest Canada suggests that three fourths of the section in Canada Basin may contain intervals of hydrocarbon source rocks and the apparent age of the basin suggests that it contains three of the six stratigraphic intervals that together provided >90?? of the World's discovered reserves of oil and gas.. Worldwide heat flow averages suggest that about two thirds of Canada Basin lies in the oil or gas window. At least five types of structural or stratigraphic features of local to regional occurrence offer exploration targets in Canada Basin. These consist of 1) a belt of late Eocene to Miocene shale-cored detachment folds containing with at least two anticlines that are capped by beds with bright spots, 2) numerous moderate to high amplitude reflection packets

    Full Text Available The term Entertainment Industry has been used interchangeably with the term Creative Industries and also has been suggested to be part of the creative industries. The creative industries seeks to provide commercially viable artistic and creative products, known as intellectual property, and in the process of such provision, contributes to the nation’s creative economy. From an education perspective in Southeast Asia, two observations can be made. Firstly, the focus of education in relation to the entertainment industry has always been technical. Secondly, the introduction of the concepts of the creative industries in Southeast Asia has spurred new trends in the education of the entertainment industry. Outside of Southeast Asia, there have been a growing number of academic programs in the field of Entertainment. From within Southeast Asia, Malaysia has taken the lead to introduce two new trends in the entertainment education – entertainment management and entertainment arts.

  7. The frequency of explosive volcanic eruptions in Southeast Asia.

    Science.gov (United States)

    Whelley, Patrick L; Newhall, Christopher G; Bradley, Kyle E

    There are ~750 active and potentially active volcanoes in Southeast Asia. Ash from eruptions of volcanic explosivity index 3 (VEI 3) and smaller pose mostly local hazards while eruptions of VEI ≥ 4 could disrupt trade, travel, and daily life in large parts of the region. We classify Southeast Asian volcanoes into five groups, using their morphology and, where known, their eruptive history and degassing style. Because the eruptive histories of most volcanoes in Southeast Asia are poorly constrained, we assume that volcanoes with similar morphologies have had similar eruption histories. Eruption histories of well-studied examples of each morphologic class serve as proxy histories for understudied volcanoes in the class. From known and proxy eruptive histories, we estimate that decadal probabilities of VEI 4-8 eruptions in Southeast Asia are nearly 1.0, ~0.6, ~0.15, ~0.012, and ~0.001, respectively.

    Lake Urmia in northwest Iran, once one of the largest hypersaline lakes in the world, has shrunk by almost 90% in area and 80% in volume during the last four decades. To improve the understanding of regional differences in water availability throughout the region and to refine the existing information on precipitation variability, this study investigated the spatial pattern of precipitation for the Lake Urmia basin. Daily rainfall time series from 122 precipitation stations with different record lengths were used to extract 15 statistical descriptors comprising 25th percentile, 75th percentile, and coefficient of variation for annual and seasonal total precipitation. Principal component analysis in association with cluster analysis identified three main homogeneous precipitation groups in the lake basin. The first sub-region (group 1) includes stations located in the center and southeast; the second sub-region (group 2) covers mostly northern and northeastern part of the basin, and the third sub-region (group 3) covers the western and southern edges of the basin. Results of principal component (PC) and clustering analyses showed that seasonal precipitation variation is the most important feature controlling the spatial pattern of precipitation in the lake basin. The 25th and 75th percentiles of winter and autumn are the most important variables controlling the spatial pattern of the first rotated principal component explaining about 32% of the total variance. Summer and spring precipitation variations are the most important variables in the second and third rotated principal components, respectively. Seasonal variation in precipitation amount and seasonality are explained by topography and influenced by the lake and westerly winds that are related to the strength of the North Atlantic Oscillation. Despite using incomplete time series with different lengths, the identified sub-regions are physically meaningful.

    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.

  10. Southeast Regional Clean Energy Policy Analysis (Revised)

    2011-04-01

    More than half of the electricity produced in the southeastern states is fuelled by coal. Although the region produces some coal, most of the states depend heavily on coal imports. Many of the region's aging coal power facilities are planned for retirement within the next 20 years. However, estimates indicate that a 20% increase in capacity is needed over that time to meet the rapidly growing demand. The most common incentives for energy efficiency in the Southeast are loans and rebates; however, total public spending on energy efficiency is limited. The most common state-level policies to support renewable energy development are personal and corporate tax incentives and loans. The region produced 1.8% of the electricity from renewable resources other than conventional hydroelectricity in 2009, half of the national average. There is significant potential for development of a biomass market in the region, as well as use of local wind, solar, methane-to-energy, small hydro, and combined heat and power resources. Options are offered for expanding and strengthening state-level policies such as decoupling, integrated resource planning, building codes, net metering, and interconnection standards to support further clean energy development. Benefits would include energy security, job creation, insurance against price fluctuations, increased value of marginal lands, and local and global environmental paybacks.

    2009-04-01

    At certain scales, flood has always been the lifeline of many people from Southeast Asian countries. People are traditionally accustomed to living with such floods and their livelihood is adjusted accordingly to optimize the benefits from the floods. However, large scale flood occasionally turns into the disaster and causes massive destruction not only in terms of human causalities but also damage to economic, ecological and social harmonies in the region. Although economic growth is prevailing in a relative term, the capacity of people to cope with such extreme events is weakening therefore the flood disaster risk is increasing in time. Recent examples of flood disaster in the region clearly show the increasing severity of disaster impact. This study reveals that there are many factors, which directly or indirectly influence the change. This paper considers the most prominent natural and socio-economic factors and analyzes their trend with respect to flood disasters in each country's context. A regional scale comparative analysis further helps to exchange the know how and to determine what kind of strategy and policy are lacking to manage the floods in a long run. It is also helpful in identifying the critical sectors that should be addressed first to mitigate the potential damage from the floods.

    Island Southeast Asia (ISEA) was first colonized by modern humans at least 45,000 years ago, but the extent to which the modern inhabitants trace their ancestry to the first settlers is a matter of debate. It is widely held, in both archaeology and linguistics, that they are largely descended from a second wave of dispersal, proto-Austronesian-speaking agriculturalists who originated in China and spread to Taiwan approximately 5,500 years ago. From there, they are thought to have dispersed into ISEA approximately 4,000 years ago, assimilating the indigenous populations. Here, we demonstrate that mitochondrial DNA diversity in the region is extremely high and includes a large number of indigenous clades. Only a fraction of these date back to the time of first settlement, and the majority appear to mark dispersals in the late-Pleistocene or early-Holocene epoch most likely triggered by postglacial flooding. There are much closer genetic links to Taiwan than to the mainland, but most of these probably predated the mid-Holocene "Out of Taiwan" event as traditionally envisioned. Only approximately 20% at most of modern mitochondrial DNAs in ISEA could be linked to such an event, suggesting that, if an agriculturalist migration did take place, it was demographically minor, at least with regard to the involvement of women.

    The history of human settlement in Southeast Asia has been complex and involved several distinct dispersal events. Here, we report the analyses of 1825 individuals from Southeast Asia including new genome-wide genotype data for 146 individuals from three Mainland Southeast Asian (Burmese, Malay and Vietnamese) and four Island Southeast Asian (Dusun, Filipino, Kankanaey and Murut) populations. While confirming the presence of previously recognised major ancestry components in the Southeast Asian population structure, we highlight the Kankanaey Igorots from the highlands of the Philippine Mountain Province as likely the closest living representatives of the source population that may have given rise to the Austronesian expansion. This conclusion rests on independent evidence from various analyses of autosomal data and uniparental markers. Given the extensive presence of trade goods, cultural and linguistic evidence of Indian influence in Southeast Asia starting from 2.5 kya, we also detect traces of a South Asian signature in different populations in the region dating to the last couple of thousand years.

    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.

    Full Text Available Graxains-do-campo habitam o centro-leste da América do Sul, desde o sudeste do Brasil e leste da Bolívia. A displasia renal compreende um espectro de anomalias e é frequentemente relatada em cães de diversas raças, sendo a maioria dos relatos achados de necropsia. A maior parte das doenças renais congênitas nos cães apresenta caráter progressivo, portanto o tratamento é limitado e direcionado a fim de retardar a progressão da doença renal estabelecida. No presente relato é descrita a realização de nefrectomia laparoscópica em graxaim-do-campo (Pseudalopex gymnocercus com displasia renal. Suspeitou-se de doença no rim direito por meio de ultrassonografia e urografia excretora. Para o procedimento cirúrgico foram utilizados três portais (10, 10, 5mm, endoscópio rígido de 10mm/0(0 e clipes para hemostasia dos vasos renais. A técnica cirúrgica utilizada neste canídeo selvagem foi semelhante à usada em cão doméstico, devido à escassez de relatos em cirurgias em graxaim e a inexistência de descrições de nefrectomia videolaparoscópica em graxaim-do-campo. O animal foi acompanhado por um período de 30 dias pós-cirurgia sem a ocorrência de complicações. O presente relato demonstra que a técnica proposta foi adequada para a realização de nefrectomia videolaparoscópica em Graxaim-do-campo.

    Full Text Available El campo del ballet es un sistema social conflictivo donde se manifiesta gran competitividad -reflejada en continuas selecciones sociales y naturales- para cumplimentar la fantasía de todos los bailarines: bailar públicamente. El objetivo de esta investigación es demostrar la pertinencia del supuesto teórico darwinista de selección natural en la discriminación de belleza escénica de la figura del bailarín en el sistema piramidal de selección, formación y desempeño profesional del campo cubano del ballet. El campo del ballet se registra fácticamente en instituciones culturales pobladas por individuos que persiguen cotidianamente crear bailarines profesionales aptos -primera condición es ser revolucionario- que representen internacionalmente a la Revolución Cubana. El campo se estructura en un sistema piramidal de selección, formación y desempeño de bailarines profesionales que rige sus prácticas principales de exclusión/inclusión -puntos de corte- por el principio darwinista de selección natural. Los exámenes de capacidades físicas de ingreso y pase de nivel a la enseñanza de nivel medio y la aceptación a la compañía profesional Ballet Nacional de Cuba conforman los puntos de corte del sistema piramidal. Estos contienen prácticas sociales que valoran -empírica, pero sistemáticamente- las características morfo-funcionales de los participantes interesados respecto al deber ser del canon artístico de figura, para seleccionar siempre a los más bellos, los más aptos, bailarines de ballet.

    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. The city of Campo Grande, the state capital of MS, presented a lower incidence/prevalence of systemic sclerosis in comparison with those numbers found in US studies and close

    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.

    The Volcanic uranium deposit of rock-magma belt-the Mid-Cz Volcano in the Southeast of China mainly formed around 120 ∼ 130 Ma and 90 ∼ 100 Ma Which is in harmony with the two rock magma activities of k within the region. The rock-magma system of this period formed around the turning period from pressure to tension in the continent margin of southeast China, which is mainly characterized by the appearance of A-type granite and alkaline, sub-alkaline rocks (trachyte, trachyandensite, trachybasalt, basic rock alkaline basalt). The uranium deposit is controlled by the base rift of dissection to the mantle, the volcanic basin is of the double characteristics of transversal rift valley basin (early period) ad tension rift valley basin (laster period). The leading role of the deep source is stressed in terms of internal-forming series of volcanic uranium deposits is considered to exist; and also in terms of internal-forming series of volcanic uranium deposits is considered to exist; and also in terms of mineral-forming patterns, the multi-pattern led by the deep-source is stressed, including the mineral-forming pattern of uranium deposit of continental thermos, repeated periphery mineral-forming pattern of uranium deposit and the mineral-forming pattern of uranium deposit of rising pole-like thermos. Ten suggestions are put forward to the next mineral-search according to the above thoughts

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.

In general, rainfall increases with altitude and decreases from west to east (south-east). It should be emphasized that (i) Lake Kinneret Basin (2,490 sq. km) was earlier divided into seven "orographic regions" and (ii) the Lake Kinneret Basin and the Yarmouk River Basin are presented by the system of regional curves X = f (Z) as one whole rainfall field in the Upper Jordan River Basin, where the mean annual rain (X) increases with altitude (Z) and decreases from west to east and from north to south. In the Yarmouk Basin there is much less rainfall (344 mm) than in the Lake Kinneret Basin (749 mm), wherein mean annual rain (2,352 MCM versus 1,865 MCM) is shared between Syria, Jordan and Israel as 80%, 15% and 5%, respectively. The provided rainfall data allow more precise estimations of surface water balances and of recharge to the regional aquifers in the Upper Jordan River Basin. The derived rates serve as fundamental input data for numerical modeling of groundwater flow. This method can be applied to other areas at different temporal and spatial scales. The general applicability makes it a very useful tool in several hydrological problems connected with assessment, management and policy-making of water resources, as well as their changes due to climate and anthropogenic factors.

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.

    The complex climatic and geological history of Southeast Asia has shaped this region’s high biodiversity. In particular, sea level fluctuations associated with repeated glacial cycles during the Pleistocene both facilitated, and limited, connectivity between populations. In this study, we used data from two mitochondrial and three anonymous nuclear markers to determine whether a fresh/brackish water killifish, Aplocheilus panchax, Hamilton, 1822, could be used to further understand how climatic oscillations and associated sea level fluctuations have shaped the distribution of biota within this region, and whether such patterns show evidence of isolation within palaeodrainage basins. Our analyses revealed three major mitochondrial clades within A. panchax. The basal divergence of A. panchax mitochondrial lineages was approximately 3.5 Ma, whilst the subsequent divergence timings of these clades occurred early Pleistocene (~2.6 Ma), proceeding through the Pleistocene. Continuous phylogeographic analysis showed a clear west-east dispersal followed by rapid radiation across Southeast Asia. Individuals from Krabi, just north of the Isthmus of Kra, were more closely related to the Indian lineages, providing further evidence for a freshwater faunal disjunction at the Isthmus of Kra biogeographic barrier. Our results suggest that Sulawesi, across the Wallace Line, was colonised relatively recently (~30 ka). Nuclear DNA is less geographically structured, although Mantel tests indicated that nuclear genetic distances were correlated with geographic proximity. Overall, these results imply that recent gene flow, as opposed to historical isolation, has been the key factor determining patterns of nuclear genetic variation in A. panchax, however, some evidence of historical isolation is retained within the mitochondrial genome. Our study further validates the existence of a major biogeographic boundary at the Kra Isthmus, and also demonstrates the use of widely distributed

    In the current changing climate globally, Ireland have been experiencing a yearly recurrent extreme heavy rainfall events in the last decade, with damaging visible effects socially, economically and on the environment. Ireland intensive agriculture production is a major treat to the aquatic environment, Nitrogen and phosphorus losses to the water courses are major causes to eutrophication. The European Water Frame Directive (WFD 2000/60/EC) and Nitrates Directive (91/676/EEC) sets a number of measures to better protect and improve water status. Five years of high temporal resolution river water quality data measurement from two contrasting catchment in the southeast of Ireland were correlated with rain fall and nutrients losses to the ground and surface water, additional to the integrated Southeast River District Basin ground and surface water quality to establish spatiotemporal connection to the agriculture activities, the first well-drained soil catchment had high coefficient correlation with rain fall with higher losses to groundwater, on the other hand higher nutrients losses to surface water were higher with less influence from groundwater recharge of N and P transfer, the poorly clay base soil contributed to higher increased losses to surface water during excessive rain fall. Agriculture activities, hydrology, geology and human interaction can interact according to their site specific setting and the effects will fluctuate dependent on the conditions influencing the impact on water quality, there is a requirement to better distinguish those effects together and identify areas and land uses control and nutrients management to improve the water quality, stakeholders co-operation along with effective polices, long term monitoring, nutrients pathways management and better understanding of the environmental factors interaction on national, regional and catchment scale to enable planning policies and enforcement measures to be more focused on areas of high risk

    The Indonesian islands and surrounding region represent one of the most submerged, low-lying continental areas on Earth. Almost half of this region, known as Sundaland, is presently inundated by a shallow sea. The role of mantle convection in driving long-wavelength topography and vertical motion of the lithosphere in this region has largely been ignored when interpreting regional stratigraphic sections, despite a consensus that Southeast Asia presently situated on a "dynamic topography low" resulting from long-term post-Pangea subduction. However, dynamic topography is typically described as a temporally and spatially transient process, implying that Sundaland may have experienced significant vertical motions in the geological past, and thus must be considered when interpreting relative sea level changes and the paleogeographic indicators of advancing and retreating shallow seas. Although the present-day low regional elevation has been attributed to the massive volume of oceanic slabs sinking in the mantle beneath Southeast Asia, a Late Cretaceous to Eocene regional unconformity indicates that shallow seas retreated following regional flooding during the mid-Cretaceous sea level highstand. During the Eocene, less than one fifth of Sundaland was submerged, despite global sea level being ~200 m higher than at present. The regional nature of the switch from marine to terrestrial environments, that is out-of-sync with eustatic sea levels, suggests that broad mantle-driven dynamic uplift may have led to the emergence of Sundaland in the Late Cretaceous and Paleocene. We use numerical forward modelling of plate tectonics and mantle convection, and compare the predicted trends of dynamic topography with evidence from regional paleogeography and eustasy to determine the extent to which mantle-driven vertical motions of the lithosphere have influenced regional basin histories in Southeast Asia.

    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.

    2017-01-01

    Full Text Available The article describes the geographical features and trends of emigration of Russian citizens to the countries of Southeast Asia on the basis of a comparative analysis of domestic and foreign statistics. The results of sociological research in these countries have been used: interviews with experts and migrant citizens of various countries of the former USSR who live or stay in Southeast Asia for more than six months. In the course of the study, a comprehensive methodology was developed and the degree of favorableness of the migration and visa regimes of the Southeast Asian countries for Russian citizens has been assessed for a number of characteristics. Factors attracting Russian citizens to the countries of the region in the context of the migration theory of the factors of “pull and push” have been revealed. The socio-demographic structure of migration flows and the geographical features of the resettlement of Russian citizens in the Southeast Asian countries have been considered. The main channels of migration of Russian citizens to the region are given: temporary labor migration, migration for permanent residence, and tourism. Several groups of Russian-speaking migrants in the Southeast Asian countries have been singled out: migrants who have moved to permanent residence, as a rule, opened their own businesses; temporary migrant workers who work for several years in Southeast Asia, are tied to work and are planning to return to Russia after some time; temporary migrants who live in Southeast Asia for several months and periodically return to Russia; Russian women who married citizens of Thailand, Vietnam, Cambodia and other Southeast Asian countries – former students who studied in the USSR and Russia. On the basis of expert assessments, the types of migration and visa regimes of the countries of Southeast Asia for Russian citizens have been highlighted.

    Sharing of water of transboundary rivers among riparian nations has become a cause of major concern in different parts of the globe for quite sometime. The issue in the recent decades has been transformed into a source of international tensions and disputes resulting in strained relationships between riparian nations. Conflicts over sharing of water of the international rivers, like the Tigris, Euphrates and Jordan in the Middle East, the Nile in Northern Africa, the Mekong in South-East Asia, the Ganga-Brahmaputra-Meghna in the Indian subcontinent are widely known. The present paper discusses the water sharing -issue in the Ganga- Brahmaputra-Meghna basin located in the Indian sub continent covering five sovereign countries (namely India, Nepal, China, Bhutan and Bangladesh). Rapidly growing population, expanding agricultural and industrial activities besides the impacts of climate change have resulted in stressed condition in the arena of fresh water availability in the basin. Again occurrence of arsenic in sub-surface water in the lower reaches of the basin in India and Bangladesh has also added a new dimension to the problem. All the rivers of the GBM system exhibit wide variations between peak and lean flows as major part of the basin belongs to the monsoon region, where 80%-90 % of annual rainfall is concentrated in 4-5 months of South -West monsoon in the subcontinent. Over and above, the rivers in GBM system carry huge loads of sediments along with the floodwater and receive huge quantum of different kinds of wastes contaminating the water of the rivers. Again high rate of sedimentation of the major rivers and their tributaries have been affecting not only the carrying capacity of the rivers but also drastically reduced their retention capacity. Almost every year during monsoon about 27% and nearly 60% of the GBM basin lying in India and Bangladesh respectively experience flood. The year round navigation in many rivers has also been affected. All these have

    This map covers the drainage basins of the upper Current River and the Eleven Point River in the Ozark Plateaus physiographic province of southeastern Missouri. The two surface drainage basins are contiguous in their headwaters regions, but are separated in their lower reaches by the lower Black River basin in the southeast corner of the map area. Numerous dye-trace studies demonstrate that in the contiguous headwaters areas, groundwater flows from the Eleven Point River basin into the Current River basin. Much of the groundwater discharge of the Eleven Point River basin emanates from Big Spring, located on the Current River. This geologic map and cross sections were produced to help fulfill a need to understand the geologic framework of the region in which this subsurface flow occurs.

    Four structural elements north of the Olympic-Wallowa lineament in the southeast part of the Columbia Plateau (Washington, Idaho, and Oregon) are (1) the offlap of progressively younger basalt units from prebasalt topographic highs; (2) east-west open folds associated with reverse faulting; (3) northwest-southeast, northeast-southwest, and north-south faults with predominantly vertical displacement; and (4) vertical north-northwest-south-southeast feeder dikes. These may be explained by (1) a regional east to west tilting of the plateau caused by the isostatic rise of older rocks on the eastern margin; (2) a stress regime with a horizontal maximum principal stress in a north-northwest-south-southeast direction, and a horizontal minimum principal stress in a west-southwest-east-northeast direction; and (3) reactivation of an older northwest-southeast, northeast-southwest, and north-south structural grain in the pre-Miocene basement. The stress regime is similar to that envisaged for the area southwest of the Olympic-Wallowa lineament, and the difference in the type of deformation on either side of that feature may be attributed to differences in the thickness of the crust across the ancient boundary

    The older population in the Southeast Asian region is accelerating and is expected to surpass the proportion of the ageing population in North America and Europe in the future. This study aims to identify the research literature related to falls among older people in Southeast Asia, to examine current practice and discuss the future direction on falls prevention and interventions in the region. A scoping review design was used. A systematic literature search was conducted using the Medline, CINAHL, AMED, Ageline, PsycINFO, Web of Sciences, Scopus, Thai-Journal Citation Index, MyCite and trial registries databases. Thirty-seven studies and six study protocols were included, from Thailand, Malaysia, Singapore, Vietnam, Indonesia and the Philippines. One-sixth of the studies involved interventions, while the remainder were observational studies. The observational studies mainly determined the falls risk factors. The intervention studies comprised multifactorial interventions and single interventions such as exercises, educational materials and visual correction. Many of the studies replicated international studies and may not have taken into account features unique to Southeast Asia. Our review has revealed studies evaluating falls and management of falls in the Southeast Asian context. More research is required from all Southeast Asian countries to prepare for the future challenges of managing falls as the population ages. Copyright © 2016 The Royal Society for Public Health.

    To gain deeper insight into the epidemiology of HIV-1 transmission in South-East Austria we performed a retrospective analysis of 259 HIV-1 partial pol sequences obtained from unique individuals newly diagnosed with HIV infection in South-East Austria from 2008 through 2014. After quality filtering, putative transmission linkages were inferred when two sequences were ≤1.5% genetically different. Multiple linkages were resolved into putative transmission clusters. Further phylogenetic analyses were performed using BEAST v1.8.1. Finally, we investigated putative links between the 259 sequences from South-East Austria and all publicly available HIV polymerase sequences in the Los Alamos National Laboratory HIV sequence database. We found that 45.6% (118/259) of the sampled sequences were genetically linked with at least one other sequence from South-East Austria forming putative transmission clusters. Clustering individuals were more likely to be men who have sex with men (MSM; pAustria had at least one putative inferred linkage with sequences from a total of 69 other countries. In conclusion, analysis of HIV-1 sequences from newly diagnosed individuals residing in South-East Austria revealed a high degree of national and international clustering mainly within MSM. Interestingly, we found that a high number of heterosexual males clustered within MSM networks, suggesting either linkage between risk groups or misrepresentation of sexual risk behaviors by subjects.

    Bathymetric, gravity and magnetic maps show that the east-west trend of the Cretaceous Great Arc of the Caribbean in the Leeward Antilles islands is transected by an en echelon series of obliquely-sheared rift basins that show right-lateral offsets ranging from 20 to 40 km. The basins are 75-100 km in length and 20-30 km in width and are composed of sub-parallel, oblique slip normal faults that define deep, bathymetric channels that bound the larger islands of the Leeward Antilles including Aruba, Curacao and Bonaire. A single basin of similar orientation and structure, the Urumaco basin, is present to the southwest in the Gulf of Venezuela. We mapped structures and sedimentation in the La Vela rift basin using a 3D seismic data volume recorded down to 6 seconds TWT. The basin can be mapped from the Falcon coast where it is correlative with the right-lateral Adicora fault mapped onshore, and its submarine extension. To the southeast of the 3D survey area, previous workers have mapped a 70-km-wide zone of northeast-striking, oblique, right-lateral faults, some with apparent right-lateral offsets of the coastline. On seismic data, the faults vary in dip from 45 to 60 degrees and exhibit maximum vertical offsets of 600 m. The La Vela and other obliquely-opening rifts accommodate right-lateral shear with linkages to intervening, east-west-striking right-lateral faults like the Adicora. The zone of oblique rifts is restricted to the trend of the Great Arc of the Caribbean and may reflect the susceptiblity of this granitic basement to active shearing. The age of onset for the basins known from previous studies on the Leeward Antilles is early Miocene. As most of these faults occur offshore their potential to generate damaging earthquakes in the densely populated Leeward Antilles is not known.

    The Southeast Regional Carbon Sequestration Partnership (SECARB) is a diverse partnership covering eleven states involving the Southern States Energy Board (SSEB) an interstate compact; regulatory agencies and/or geological surveys from member states; the Electric Power Research Institute (EPRI); academic institutions; a Native American enterprise; and multiple entities from the private sector. Figure 1 shows the team structure for the partnership. In addition to the Technical Team, the Technology Coalition, an alliance of auxiliary participants, in the project lends yet more strength and support to the project. The Technology Coalition, with its diverse representation of various sectors, is integral to the technical information transfer, outreach, and public perception activities of the partnership. The Technology Coalition members, shown in Figure 2, also provide a breadth of knowledge and capabilities in the multiplicity of technologies needed to assure a successful outcome to the project and serve as an extremely important asset to the partnership. The eleven states comprising the multi-state region are: Alabama; Arkansas; Florida; Georgia; Louisiana; Mississippi; North Carolina; South Carolina; Tennessee; Texas; and Virginia. The states making up the SECARB area are illustrated in Figure 3. The primary objectives of the SECARB project include: (1) Supporting the U.S. Department of Energy (DOE) Carbon Sequestration Program by promoting the development of a framework and infrastructure necessary for the validation and deployment of carbon sequestration technologies. This requires the development of relevant data to reduce the uncertainties and risks that are barriers to sequestration, especially for geologic storage in the SECARB region. Information and knowledge are the keys to establishing a regional carbon dioxide (CO{sub 2}) storage industry with public acceptance.

    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

  5. A major seasonal phytoplankton bloom in the Madagascar Basin

    A hitherto-unnoticed phytoplankton bloom, of dimension 3000×1500 km, occupies the Madagascar Basin in late austral summer, being a prominent feature in SeaWiFS images. A first-order interpretation of the bloom mechanism invokes the seasonal deepening of the mixed layer within a strong mesoscale eddy-field and the consequent entrainment of nutrients into the photic zone. Features of the bloom correspond closely and appropriately with features of the eddy-field as observed by TOPEX-POSEIDON sea level anomalies. The bloom failed to develop in 1998, the second year of a two-year ENSO episode, when anomalously weak Southeast Trades will have failed to deepen the mixed layer as in other years.

    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

    Full Text Available América Latina es considerada la región más desigual del planeta. Es el Continente donde, según múltiples fuentes, las polarizaciones son mayores en diversos campos, y el acceso a las oportunidades es marcadamente disímil para los diferentes sectores sociales. ¿Cómo impacta la inequidad latinoamericana el fundamental campo de la salud? ¿Qué problemas determina en esta área decisiva de la vida de las sociedades, y qué obstáculos y trabas pone al avance de los esfuerzos para mejorar la salud?.A pesar de su clara relevancia, este tema ha sido limitadamente puesto a foco. El objetivo de este trabajo es llamar la atención sobre el mismo, y contribuir a estimular este debate tan necesario. Para ello se subraya, en primer término, el papel central de la salud para el desarrollo, se reseñan las amplias brechas que existen, a pesar de ello, a nivel mundial entre países, y a su interior, se encaran ciertos difundidos mitos sobre cómo superar los problemas en salud, se exploran algunos de los principales impactos de la desigualdad de América Latina sobre aspectos básicos del campo de la salud y, finalmente, se sugieren algunas líneas de la gran tarea por realizar para enfrentar el peso de la inequidad sobre la salud pública.

A pesquisa de campo foi feita no município de Itacaré, sul do estado da Bahia, com o propósito compreender como os sujeitos de Itacaré percebem o rio das Contas, qual é o significado do rio para eles. Como método de pesquisa de campo, optamos pela história oral e pelas técnicas da entrevista, da observação e, ainda, pelo registro de paisagens através de fotografias. A nossa presença em Itacaré foi importante para o êxito da pesquisa porque pudemos conhecer melhor as pessoas e o seu cotidiano, fato que contribuiu para a qualidade das informações contidas nas 41 entrevistas feitas. Também, essa convivência com as pessoas do lugar foi uma grande experiência vivida na perspectiva da Geografia Humanista.

    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 contrast, forested sites on canga are recognized as Yodfels. To be effective

    Full Text Available Colonialism and indigenous responses to its varied forms dominate modern Asian historiography and imbue the history of the region with rich and multifaceted connections to world history. As a result, the histories of East and Southeast Asian nation-states since 1500 cannot be viewed outside of the context of global affairs. Imagining Asian peoples and cultures during this time is problematic for students, who typically approach colonialism from a western perspective. This presentation explores various means of incorporating into the classroom pedagogical materials and diverse media sources that facilitate a more grounded examination of East and Southeast Asian colonies, peoples, and nation-states.It pays special attention to teaching colonialism, anti-colonialism, nationalism, and transnationalism from the perspective of Southeast Asia’s indigenous peoples.

    Development of East Asia's petrochemical industry has been phenomenal, with major complexes built in numerous locations. The Southeast Asian countries of particular interest are members of the Association of Southeast Asian Nations (ASEAN): Singapore, Thailand, Malaysia, Indonesia, the Philippines, Brunei and Vietnam. As new capacity is built in this region, these large operating facilities will affect supply and demand for key petrochemical products--ethylene and polyolefins. What are the potential regional effects from this new capacity? Traditional net export countries will have to re-evaluate their future marketing strategies to remain competitive in Southeast Asia and other trading areas. As East Asia's petrochemical industry comes of age, competition will undoubtedly increase. However, this growing region offers opportunities to widen manufacturing basis. The paper discusses basic chemical demands and the outlook for the Asian petrochemical industry

La rica variedad paisajística que atesora necesita una intensa gestión de conservación para su puesta en valor como recurso imprescindible. Las diferentes encuestas entre población y visitantes, nos han proporcionado un pormenorizado análisis a escala local, a su vez compaginado con el trabajo de campo, por lo que hemos podido contrastar la percepción que de su paisaje tienen tanto los propios residentes como los agentes sociales de los aspectos y realidades de los distintos paisajes del territorio analizado. Si evaluamos los rasgos que identifican a este paisaje, fuertemente ligado al modo de vida de las personas que lo habitan, está llamado a una rápida desaparición ante los constantes cambios desarrollados en estas últimas décadas, por lo que su protección es necesaria y debe estar lo suficientemente reflejada en los documentos base para su buena gestión. Consideramos factores fundamentales para la gestión efectiva del paisaje en el territorio las llamadas Agendas 21, la importancia patrimonial de la ciudad de Chinchilla y el desarrollo turístico.The article takes as starting point the territory of the Campo de Albacete, an area where the influence of the capital city in the surrounding towns is stated.

  4. Trace element and isotopic compositions of Vietnamese basalts: implications for mantle dynamics in the southeast Asian region

    Cenozoic basalts in Indo-China are part of a regional melting episode along the rifted Eurasian margin. Trace element and isotopic compositions of Vietnamese basalts are used to place constraints on the extent of lithospheric and asthenosphere contributions to the melts and possible mantle dynamic implications. The 87 Sr/ 86 Sr, 207 Pb/ 204 Pb, and 208 Pb/ 204 Pb isotopic ratios of the basalts reflect minimal crustal wall rock reaction, and variable enrichment in EM1 and EM2 of a 208 Pb-rich MORB-like source. Some, but not all, of this variation corresponds to the age of lithospheric sector penetrated. Basalts erupted through a cratonic, central sector (e.g. at Quang Ngai, Pleiku, Song Cau, Kong Plong, and Buon Ma Thuot) and off-cratonic, southwest sector (e.g. Phuoc Long) resemble those of EM2-rich basalts from southern and southeaster China and the South China Sea. Basalts from an off-cratonic, southeast sector (e.g. from Dalat, Xuan Loc, and the offshore Ile des Cendres-Phu Cuy complex) reflect mixing between a low- 206 Pb/ 204 Pb, high- 208 Pb/ 204 Pb, EM1-like component, and resemble basalts from northwest Taiwan, eastern and northeastern China, and parts of the Japan Sea. While EM2 tends to characterise lithospheric sectors, presence of EM1 in off-cratonic rather than cratonic basalts implies an asthenosphere rather than lithospheric source. Pervasive presence of EM1 in southeast Asian and marginal basin asthenosphere corresponds with thermally-anomalous mantle and may involve delaminated cratonic substrate entrained by mobile, extruded asthenosphere.

    Full Text Available From 2007 onwards, with the change of presidency in Argentina and the consolidation of the internal recovery, the orientation of foreign policy acquires more autonomist nuances. It is in this scenario that the links with less developed countries - or of the South - should be understood, including the ties with the economies of Southeast Asia. Our objective in this work is to analyze the current state of Argentina’s bilateral ties with Southeast Asia - with special emphasis on the Philippines -analyzing these bonds as an alternative for insertion within a strategy of selective diversification and extension of margins of autonomy.

  6. Oil refining and product marketing developments in southeast Asia

    International Nuclear Information System (INIS)

    Szabo, A.M.

    1992-01-01

    Views on the future are based on supplies from a relatively stable Middle East and continued economic growth in the southeast Asian and Pacific countries. Under these circumstances the oil market for the Association of Southeast Asian Nations (ASEAN) will expand considerably during the decade of the 90's. Pacific country demand, 5.92 MMB/D, in 1990 is likely to grow to 7.06 MMB/D in 2000. Regional production could supply about 40% of this. The Asia-Pacific shortage of refining capacity could lead to high regional refined product prices and health refining profit margins. (author)

  7. Will biofuel projects in Southeast Asia become white elephants?

    International Nuclear Information System (INIS)

    Goh, Chun Sheng; Lee, Keat Teong

    2010-01-01

    Southeast Asia's attempt to join the global biofuel development has not been very successful, despite the large amount of subsidies and incentives allotted for biofuel projects. The outcome of these projects has failed to meet expectation due to overrated assumptions and shortsighted policies. Utilization of edible feedstock such as palm oil and sugar cane for biofuel has disrupted the fragile industry due to the fluctuations of feedstock prices. The appropriate research on jatropha to prove its economic and environmental feasibility as energy crop has not been performed. Biofuel development in Southeast Asia remains at an early stage of development and requires highly intensive monitoring and strict legal enforcement to ensure future success.

    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)

    The deposition of the Stuttgart Formation ('Schilfsandstein'), commonly considered as a type-example of the Carnian Pluvial Event, was controlled by high frequent 4th order sequences that resulted in pre-, intra- and post-Schilfsandstein transgressions from Tethyan waters into the epicontinental Central European Basin (CEB). The pre-Schilfsandstein transgression flooded the CEB trough gates to the Southeast and resulted in a wide-spread inland sea that was characterised by increased biological productivity, predominantly oxic conditions and enabled the immigration of euryhaline marine fauna with plankton, ostracodes, fishes, bivalves and the gastropods Omphaloptychia suebica n. sp. and Settsassia stuttgartica n. sp. The rather short-term intra- and post-Schilfsandstein transgressions flooded the CEB from the Southwest and Southeast and established a shallow brackish inland sea that stretched up to North Germany. Both, the 4th and 3rd order sequences derived from the succession in the CEB correlate well with those derived from successions of Tethyan shelfs. Therefore pronounced circum-Tethyan eustatic cycles are evidenced and may have had considerable impact on prominent middle Carnian events: Reingraben turnover, Carnian Pluvial Event, Carnian Crisis and Mid Carnian Wet Intermezzo. The broad circum-Tethyan evidence of 106-year scale cycles suggests glacioeustatic sea-level changes even in the Triassic Greenhouse period.

La producción en el entorno rural conoció un amplio desarrollo basado en la producción de paños de calidad media-baja destinados al consumo interno, y dio lugar a formas organizativas complejas que se constituyeron en una alternativa frente al sistema gremial imperante en la urbe palentina, implicando intereses de un amplio espectro de grupos sociales.ABSTRACT: The present article aims to analyze the spreading of the rural textile industry in the region of Tierra de Campos in the late fifteenth and the early sixteenth centuries, around the traditional productive centre of Palencia. Here rural clothing experienced an important development based on the production of low and medium quality cloth under a putting-out system directed to interregional trade. The interests around rural industry involved a wide range of social groups, giving rise to complex organization forms and arising as an alternative to the traditional gudd stmcture.

    Full Text Available O presente artigo, de caráter ensaístico, visa a contribuir com reflexões sobre modernidade, turismo e campo social sociais no Estado de Alagoas - Brasil. Utilizando o referencial de autores como Giddens (2001, Jameson (2002 e Harvey (1992, dentre outros, sintetizaremos algumas características das transições socioculturais da modernidade para o atual estágio do modo de produção capitalista, período que muitos têm considerado como a “pós-modernidade”. Posteriormente, empreenderemos breve descrição crítica acerca do atual modelo de turistificação no Estado, com base nos conceitos de Habitus e Campo Social, de Pierre Bourdieu. Conclui-se que o turismo em Alagoas está ancorado em roteiros que, em sua dominância, têm se consolidado sob os enunciados de Sol e Mar, tendência natural do turismo de massa que ocorre nas regiões intertropicais do mundo inteiro, em caso mais especifico, no Nordeste Brasileiro, e que também sofre direta influência da formação histórica de uma cultura de alheamento às potencialidades dos patrimônios identitários locais.

(Rubiaceae species occurring in the Brazilian Cerrado and Campo Rupestre ecosystems. Anatomical analysis was performed in fresh or fixed leaves processed with usual plant microtechnique. 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.

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".

    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.

  6. Novo do velho: a poesia experimental dos poetas ensaístas Haroldo e Augusto de Campos

    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)

  12. Intermediate transport in Southeast Asia. [Carts, cycles, mini-buses

    Energy Technology Data Exchange (ETDEWEB)

    Meier, A.K.

    1977-06-01

    Traffic flows through the streets of Southeast Asian countries even though they are used for almost all aspects of human and animal existence. The carts, bicycles, tricycles, and motorcycles, motorized three-wheelers, mini-buses are the so-called intermediate-transport vehicles. It is upon this group of vehicles that a culture--constrained by its own unique economic, environmental, and technological factors--exerts its influence most directly toward the solution of the transport problem. Transportation fills more service roles in Southeast Asian cities than in Western cities. Communication facilities such as telephones and postal services are notoriously unreliable. The personal encounter is all important in social and business interactions in Southeast Asia. Each of the transport modes is examined in view of design and use in a number of specific cultural settings for the countries in Southeast Asia. Present use of intermediate transport in developed countries is discussed briefly, and its further development predicted--pointing out the health and conservation advantages. (MCW)

    2013-03-01

    Studies of doctor-patient communication generally advocate a partnership communication style. However, in Southeast Asian settings, we often see a more one-way style with little input from the patient. We investigated factors underlying the use of a one-way consultation style by doctors in a Southeast Asian setting. We conducted a qualitative study based on principles of grounded theory. Twenty residents and specialists and 20 patients of a low or high educational level were interviewed in internal medicine outpatient clinics of an Indonesian teaching hospital and two affiliated hospitals. During 26 weeks we engaged in an iterative interview and coding process to identify emergent factors. Patients were generally dissatisfied with doctors' communication style. The doctors indicated that they did not deliberately use a one-way style. Communication style appeared to be associated with characteristics of Southeast Asian culture, the health care setting and medical education. Doctor-patient communication appeared to be affected by cultural characteristics which fell into two broad categories representing key features of Southeast Asian culture, "social distance" and "closeness of relationships", and to characteristics categorized as "specific clinical context". Consideration of these characteristics could be helpful in promoting the use of a partnership communication style.

  20. Seasonal variation of limnological features and trophic state index of two oligotrophic reservoirs of southeast Brazil.

    Science.gov (United States)

    Oliveira, S A; Bicudo, C E M

    2017-01-01

    Limnological features of two reservoirs were studied in dry (August 2013) and rainy (January 2014) periods to evaluate the water quality that supply the city of Guarulhos, southeast Brazil. Water samples were collected in three depths and the following characteristics were measured: alkalinity, dissolved O2, free and total CO2, HCO3, soluble reactive silica, dissolved and total nitrogen and phosphorus, and chlorophyll-a. Water transparency was also measured and temperature, pH and electric conductivity profiles were obtained. Great seasonal and low spatial variability of the water characteristics occurred in the reservoirs. High values of water transparency, free CO2 availability, and low of pH, soluble reactive silica and total and dissolved nutrients values were recorded at the dry period, and different conditions were found at the rainy season. The two reservoirs were characterized by low nutrients, chlorophyll-a and turbidity, and high transparency, these features being typical of oligotrophic systems. The two reservoirs still remain under low anthropogenic impact conditions, and are presently considered reference systems for the SPMR, São Paulo Metropolitan Region. The need for actions that will reduce the input of nutrients from the neighboring cities and the main tributaries of the hydrographic basin is emphasized to maintain the ecological quality of the reservoirs and their reference conditions among the SPRM reservoirs.
