  3. Evaluation of the behavior of a hundred dentists concerning to radiation protection in the city of Aracatuba, Sao Paulo State

    International Nuclear Information System (INIS)

    The aim of the study was to evaluate the behavior of 100 dentists concerned to radiation protection in the city of Aracatuba, Sao Paulo State. Each dental office was visited, and a form was filled out by the dentists, with questions regarding the radiation protection of the patient, operator and staff. in the same visit, a radiography was taken using a phantom and processed according to the professionals'routine, to determine its diagnostic accuracy. After data analysis, we concluded that the dentists are not using satisfactorily the radiological sources, and the exposure and processing conditions could be improved. We also concluded that the professionals tend to task the radiographs after the clinical examination of the mouth, to reduce the number of the X-ray/patient ratio. Another conclusion is that the biological hazards from xradiation is not significant because of the small number of dental radiographs taken monthly. (author)

    Earth's middle and upper atmosphere exhibits several dominant large scale oscillations in many measured parameters. One of these oscillations is the semi-annual oscillation (SAO). The SAO can be detected in the ionospheric total electron content (TEC), the ionospheric transition height, the wind regime in the mesosphere-lower-thermosphere (MLT), and in the MLT temperatures. In addition, as we report for the first time in this study, the SAO is among the most dominant oscillations in nighttime very low frequencies (VLF) narrow-band subionospheric measurements. As VLF signals are reflected off the ionospheric D-region (at altitudes of ~65 and ~85 km, during the day and night, respectively), this implies that the upper part of the D-region is experiencing this oscillation as well, through changes in the dominating electron or ion densities, or by changes in the electron collision frequency, recombination rates, and attachment rates, all of which could be driven by oscillatory MLT temperature changes. We conclude that the main source of the SAO in the nighttime D-region is due to NOx molecules transport from the lower levels of the thermosphere, resulting in enhanced ionization and the creation of free electrons in the nighttime D-region, thus modulating the SAO signature in VLF NB measurements. While the cause for the observed SAO is still a subject of debate, this oscillation should be taken into account when modeling the D-region in general and VLF wave propagation in particular.

  11. Atmospheric pollution biomonitoring of the Sao Paulo metropolitan region using epiphytic lichens

    International Nuclear Information System (INIS)

    Due to the increasing problems of atmospheric pollution in the Sao Paulo metropolitan region that affect the environment and human health the application of biomonitoring methodologies using cosmopolite organisms has now become relevant. Biomonitoring is a method to evaluate the response of live organisms to pollution. This method offers advantages such as reduced costs, efficient monitoring of large geographic areas and accumulated pollutants over a large period in which low concentrations of chemicals elements in the environment can be evaluated. In the present study, neutron activation analysis method was applied to determine elements accumulated in Canoparmelia texana lichenized fungi. Samples were collected in two distinct areas: Carlos Botelho (PECB) and Intervales (PEI) State Parks that are considered as non-polluted areas and that belong to the Atlantic Forest - SP ecosystem; and Sao Paulo city metropolitan region in sites near automatic monitoring stations of the Environmental Protection Agency of the State of Sao Paulo (CETESB). The lichens collected from the bark of the trees were properly treated, and irradiated with neutrons from IEA-R1 nuclear reactor along with synthetic standards of elements. The precision and the accuracy of the results were evaluated by the analyses of IAEA-336 LICHEN and Mixed Polish Herbs (INCT -MPH-2) certified reference materials. The results obtained for these materials were in accordance with the certified values and presented good precision with variation coefficients ranging from 0.9 to 14.6%. Results obtained for lichens showed that elements As, Co, Cr, Cs, La, Mo, Sb, Sc, Se and U are present at ng g-1 levels, Ba, Br, Cl, Fe, K, Mn, Na, Rb and Zn at μg g-1 and Ca at mg g-1. By applying cluster and discriminant analyses to the results for the lichen samples from areas with different levels of pollution, the sampling sites were grouped according to their chemical similarities and their elemental composition.

    Full Text Available OBJECTIVE To evaluate the individual and contextual determinants of the use of health care services in the metropolitan region of Sao Paulo. METHODS Data from the Sao Paulo Megacity study – the Brazilian version of the World Mental Health Survey multicenter study – were used. A total of 3,588 adults living in 69 neighborhoods in the metropolitan region of Sao Paulo, SP, Southeastern Brazil, including 38 municipalities and 31 neighboring districts, were selected using multistratified sampling of the non-institutionalized population. Multilevel Bayesian logistic models were adjusted to identify the individual and contextual determinants of the use of health care services in the past 12 months and presence of a regular physician for routine care. RESULTS The contextual characteristics of the place of residence (income inequality, violence, and median income showed no significant correlation (p > 0.05 with the use of health care services or with the presence of a regular physician for routine care. The only exception was the negative correlation between living in areas with high income inequality and presence of a regular physician (OR: 0.77; 95%CI 0.60;0.99 after controlling for individual characteristics. The study revealed a strong and consistent correlation between individual characteristics (mainly education and possession of health insurance, use of health care services, and presence of a regular physician. Presence of chronic and mental illnesses was strongly correlated with the use of health care services in the past year (regardless of the individual characteristics but not with the presence of a regular physician. CONCLUSIONS Individual characteristics including higher education and possession of health insurance were important determinants of the use of health care services in the metropolitan area of Sao Paulo. A better understanding of these determinants is essential for the development of public policies that promote equitable use

  15. Natural radionuclides in the Brazilian coast region: 1. Estuarine complex Cananeia-Iguape, Sao Paulo State

    International Nuclear Information System (INIS)

    Mangrove forests are of utmost important ecosystems for biogeochemical transport processes in a global scale because of the preferential transport via sediments and organic matter from continents to oceans. Such ecosystems are the richest biodiversity areas, in which bioaccumulation of chemical substances can be expected for some species, in this case, there is a lack of knowledge of natural radionuclides accumulation in mangrove vegetation. This work encompasses the first results obtained for the Estuarine Complex Cananeia-Iguape, a peculiar coast area of the Sao Paulo State, Brazil. In 2011, leaf samples of Rhyzophora mangle and Laguncularia racemosa trees with perimeter at the breast height higher than 15 cm were collected in the conservation unit Parque Estadual Ilha do Cardoso. Sample preparation consisted of leaf washing, oven-drying, milling in porcelain mortar at the particle size lower than 0.5 mm. Portions of 10 g were transferred to polyethylene vials of appropriate geometry for the analysis by high resolution gamma-ray spectrometry. Reference materials were analyzed together to evaluate the quality of the analytical procedure. K-40 was preferentially allocated in leaves. Some accumulation in leaves was noticed for Pb-210 and Ac-228 depending on the species, indicating differences of radionuclide distribution in the mangrove vegetation. (author)

  17. Lead-lead isotope method. Application to migmatites and associaded rocks of the region of Sao Jose dos Campos, SP

    International Nuclear Information System (INIS)

    Establishment of chemical and analytical procedures, preparation and purification of reagents and the mounting of a clean laboratory (class 100) for the Pb-Pb isotope dating of whole rock and mineral samples are discussed in this work. Two different methods of dissolution of rock samples and chemical separation of lead using anionic resin were tried in a conventional chemical laboratory using analytical grade reagents. The samples analysed were paleossome and neossome of migmatites from Sao Jose dos Campos, SP, and from the results obtained the analytical method to be employed was chosen. The results obtained by this method agree well with those of the Geochronology Laboratory at Oxford, for the same samples. Applying the established analytical procedure, migmatites and associated gneisses from the region of Sao Jose dos Campos were dated by Pb/Pb method. Some of the samples were also dated by Rb-Sr method. The lead-lead isochron age of 2355 +- 85 M.a. (μ1 = 8.33) for the paleossome may be interpreted as the age of the metamorphism for these rocks, which were formed probably during the Archean. The age data for the phacoidal gneisses show a similar geological evolution, whereas the 2414 +- 800 M.A. Pb-Pb isochron age for the protomylonitic gneisses indicates a disturbed Pb-Pb isotope system. The neossome samples define a Pb-Pb isochron age of 1388 +- 290 M.A. (μ1 = 8.15), which may be interpreted as the age of migmatization. The calculated Pb-Pb ages for two alkali feldspars from the migmatites are devoid of any geological significance. The age values obtained by the Rb-Sr isotope system for the neossome and paleossome of the migmatites agree with the Pb/Pb data within experimental errors. However, the study shows that results of the Rb-Sr data alone cannot be interpreted unambiguously with out comparison with data from other isotope systems. (author)

    The present work has in view the elaboration of projections based on IRP (Integrated Energy Resources Planning) in order to propose an alternative of sustainable development to one region of the State of Sao Paulo. Using the data of the region, gathered in the past years by several researches of the GEPEA-USP, scenarios of the development and consume of energy have been created. In these scenarios, two possibilities to supply the demand of the region were considered: energy of clean sources and/or renewable as well as energy of sources that have lower costs. In order to simulate the behavior of several factors of the offer and demand, the LEAP (Long-range Energy Alternatives Planning) has been used. Both scenarios have vantages and disadvantages, but the clean sources scenario certainly could supply the needs of the region for the next twenty years. Uncertainties in longer periods make the forecasts no much reliable, because changes in both, demand and offer, could invalidate the study. The best is an accompaniment of the sector's behavior in order to make shorter projections, ten years for example, to set the generator estate and policies of consumption. Long forecasts are good to show the limits of the system and the reserve to preview emergency situations as occurred in 2001 with shortness of water supply and consequently broke of energy catering.

  20. Study of the demand for radiopharmaceutical 18F-FDG in the metropolitan regions of Sao Paulo and adjacent areas

    International Nuclear Information System (INIS)

    Nuclear Medicine in Brazil and worldwide has developed distinction with diagnosis techniques that allow metabolic research of the disease, changing in a significant fashion the patient's outcome. This innovative technology leads expectations from specific fields up to society itself. This research studied the use of 18F-FDG radiopharmaceutical in the metropolitan region of Sao Paulo and adjacent areas, as well as the recent trade structure and the difficulties that should be overcome with the increase of the 18F-FDG demand. This research counted on the analysis of the international radiopharmaceutical trade and the main changes that have been happening in this area in Brazil during the past few years. Interviews were performed with professionals within the area of nuclear medicine and data has been collected through questionnaire sent to the consuming centers of the radiopharmaceutical in the region covered in this research. The interviews expressed the opinions of the interviewees concerning transformations in this field and future tendencies and the information obtained from the survey was the basis of complementation of the use of radiopharmaceutical on equipment such as Single Photon Emission Computed Tomography (SPECT), Positron Emission Tomography (PET) and Positron Emission Tomography I Computer Tomography (PET/CT). The major use of 18F-FDG has been used for oncology diagnosis with equipment such as PET and PEC/CT. This use shall grow in the next years, maybe expanding to other specialties such as neurology and cardiology. Although nowadays restricted to the cities of Sao Paulo and Rio de Janeiro, there is a possibility of expansion to other diagnosis modalities in other states of the country that are starting to structure the production of the radioisotope. The recent change in the constitution permitting the production and commerce of short half-life radioisotopes also contributes to the increase the interest of private funding of this sector in which

  1. Assessment of atmospheric metallic pollution in the metropolitan region of Sao Paulo, Brazil, employing Tillandsia usneoides L. as biomonitor

    International Nuclear Information System (INIS)

    Tillandsia usneoides L. is an epiphytic bromeliad that lives on trees or other kinds of inert substrates, absorbing water and nutrients directly from the environment without roots. Due to its morphological and physiological characteristics, this species accumulates the pollutants present in the atmosphere. In the present work, Tillandsia usneoides was used as a bio monitor of metal atmospheric pollution in Sao Paulo, Brazil, which is the biggest city in South America with a population of 18 million inhabitants and a strong industrial activity. The urban area is polluted by industrial emissions but, according to the Environmental Protection Agency of the State of Sao Paulo (CETESB), the governmental agency of air quality control, regularly occurring emissions from about 7.8 million motor vehicles provide the principal source of air pollution. The Tillandsia samples were collected from an unpolluted area and were exposed bimonthly in 10 sites of the city with different pollution levels and in a control site. After exposure, trace metals were analyzed in the plant by instrumental neutron activation analysis and ICP-MS (Pb, Cd, Co, Cu, Ni, Sb e V). The results of the investigation showed a notable concentration of Co and Ni in the plants exposed in an industrial area where there is a metal processing plant, which produces about 600 tons/year of Co and 16,000 tons/year of Ni. Copper and chromium were equally distributed in industrial regions and in sites near heavy traffic avenues, suggesting that these elements can be associated to both vehicular and industrial sources. A high accumulation of Cd in the plant exposed in industrial areas indicates industrial activities as the main source of this element. For Pb, no evident sources could be identified so far as it was spread evenly along the monitoring sites. Traffic-related elements such as Zn, Ba and Sb presented high concentrations in plants exposed in sites near to heavy traffic avenues (cars, buses and trucks) and

  3. Assessment of contamination for inorganic elements and phthalate esters in household dust from the metropolitan region of Sao Paulo

    International Nuclear Information System (INIS)

    Household dust has been identified as an important vector of exposure by inorganic and organic substances potentially toxic in children and adults. The dust composition has a strong influence of contaminants provided from internal and external environments. During the natural process of wearing or weather incidents of artifacts and materials variety, the chemical substances are released into the environment in the steam form or by leaching from final products. Once released, they can be accumulated and enriched in the dust; and by continuous exposure (inhalation, ingestion and dermal contact mechanisms), these substances are harmful to human health. In this work, a study to determine the inorganic constituents and phthalate esters concentrations in residential indoor environment dust samples, correlating them with the probable anthropogenic sources was proposed. Dust samples were collected from 69 residences in neighborhoods Pirituba, Freguesia do O, Jaragua and Perus of the Sao Paulo metropolitan region, using a domestic vacuum cleaner, between 2006 and 2008. The samples were sieved in the fractions of 850, 850-300, 300-150, 150-75, 75-63 and <63 μm. The analysis by X-ray fluorescence (WDXRF) showed the presence of Na, Mg, Al, Si, P, S, Cl, K, Ca, Ti, Cr, Mn, Fe, Ni, Cu, Zn, Br, Rb, Sr, Zr and Pb. The presence of phthalate esters (DEHP, DnBP, DEP, DEHA, DMP and BBP) was detected, by GCMS analyses. From the enrichment factor (EF), the elements P, S, Cr, Ni, Cu, Zn and Pb were classified as being significant and extremely enriched in the dust. The natural and anthropogenic contributions by statistical tools as factor analysis (AF) and cluster were identified. The elements Cr, Ni, Cu, Zn and Pb were present significantly elevated concentrations in relation to the total exposure values (ingestion, inhalation and skin contact) and to risk. (author)

    Full Text Available Objective: To identify the process of dispensation of orthotics, prostheses and mobility aids (OPM by the Unified Health System (SUS in the Regional Health Department of the 3rd Region (DRSIII of Sao Paulo state; perform a mapping of the existing physical rehabilitation services in that region; and subsequently correlate the data with applicable laws. Methodology: This is an exploratory cross-sectional qualitative study whose subjects were the main professionals involved in the process of OPM dispensation, or responsible for their acquisition flow in the cities of that region. Data collection was carried out through a semi-structured questionnaire, developed by the researchers themselves, composed of questions aiming to identify the physical rehabilitation centers in the towns, the staff members involved, the provision of assistive technology through SUS, delivery time and existence of waiting lists. Results and discussion: The data were statistically measured, categorized, described and correlated with the current legislation aimed to guarantee access to assistive technology. We observed that the practice around this resource in the 3rd region concentrates in a single care center, causing long waits and poor efficiency of the services provided, in addition to maintaining a paternalistic aspect. Conclusion: This study provides evidence that, although the right to access to assistive technology is legally guaranteed, there are still many difficulties and challenges around this practice.

    Tillandsia usneoides L. is an epiphytic bromeliad that lives on trees or other kinds of inert substrates, absorbing water and nutrients directly from the environment without roots. Due to its morphological and physiological characteristics, this species accumulates the pollutants present in the atmosphere. In the present work, Tillandsia usneoides was used as a bio monitor of metal atmospheric pollution in Sao Paulo, Brazil, which is the biggest city in South America with a population of 18 million inhabitants and a strong industrial activity. The urban area is polluted by industrial emissions but, according to the Environmental Protection Agency of the State of Sao Paulo (CETESB), the governmental agency of air quality control, regularly occurring emissions from about 7.8 million motor vehicles provide the principal source of air pollution. The Tillandsia samples were collected from an unpolluted area and were exposed bimonthly in 10 sites of the city with different pollution levels and in a control site. After exposure, trace metals were analyzed in the plant by instrumental neutron activation analysis and ICP-MS (Pb, Cd, Co, Cu, Ni, Sb e V). The results of the investigation showed a notable concentration of Co and Ni in the plants exposed in an industrial area where there is a metal processing plant, which produces about 600 tons/year of Co and 16,000 tons/year of Ni. Copper and chromium were equally distributed in industrial regions and in sites near heavy traffic avenues, suggesting that these elements can be associated to both vehicular and industrial sources. A high accumulation of Cd in the plant exposed in industrial areas indicates industrial activities as the main source of this element. For Pb, no evident sources could be identified so far as it was spread evenly along the monitoring sites. Traffic-related elements such as Zn, Ba and Sb presented high concentrations in plants exposed in sites near to heavy traffic avenues (cars, buses and trucks) and

  8. Pb/Pb single-zircon dating of Paleoproterozoic calc-alkaline/alkaline magmatism in the southeastern Sao Francisco Craton region, Brazil

    International Nuclear Information System (INIS)

    Two chemically and petrographically distinct intrusive bodies (a calc-alkaline trondhjemite and an alkaline quartz-syenite cut by granitic aplites) occur in the vicinity of Piranga (Minas Gerais State), near the southeastern border of the Sao Francisco craton, Brazil. They intrude the Rio das Velhas greenstone belt and the Mantiqueira complex, both of Archean age. Both intrusive bodies are variably deformed and mylonitized. Age determinations using the Pb/Pb single-zircon evaporation method yielded paleoproterozoic ages for the emplacement/crystallization of the trondhjemite (2058 ± 10 Ma, quartz-syenite (2036 ±4 Ma), as well as the younger aplites (2012 ± 8 Ma). These ages allow us to interpret the calc-alkaline as well as alkaline magmatism as manifestations of the Transamazonian event in the southeastern Sao Francisco craton region. Furthermore, the calc-alkaline trondhjemite is interpreted to have intrude during compressional deformation, while the alkaline quartz-syenite and its aplitic differentiates are post-orogenic, possibly extension-related In terms of the Rb vs. (Y+Nb) contents, the trondhjemite plots in the field of volcanic are granites, whereas the syenite and the aplites plot in the of post-collision granites. The mylonitic overprinting of the syenite and the trondhjemite is also Paleoproterozoic, as deduced from 2012± 8 Ma age of the undeformed younger aplitic dykes which cut the syenite. It is likely that this alkaline magmatism with a Paleoproterozoic post-collisional magmatic event well documented in the Transamazonian mobile belts of the northern Sao Francisco craton. (author)

    This paper aims to present a systemic model for analysis of the expansion and grow up of the natural gas distribution pipeline in a city. This methodology integrates the understanding of the urban dynamics to the strategies of expansion in the natural gas distribution network, through the grouping of information such as family income, demographic density and construction area, percentage of land use, number of households as well as commercial, service and industrial establishments, number of real state as well as indicative information released by the Urban Plan of the city regarding the increments in the peripheral districts. Relating the gas consumption esteemed by each type of land occupation and the cost for expanding the gas distribution network, the model will indicate, for each neighborhood, the viability of implementing a gas network as well as the places with potential for growing density in the existing gas distribution system. The aim is to propose an integration of aspects of city dynamics and new energy source development, taking the advance of natural gas in Sao Paulo Metropolitan area as a specific case study. Through the analysis of highly industrialized, residential and commercial suburbs of the City of Sao Caetano do Sul, the importance of urban parameters in the decision making process for network expansion is identified.

    This study aimed to assess the variation of trace element concentrations present in great egret livers during six years, from 2006 to 2011. The data were obtained in twenty six livers of great egrets from the Sao Paulo Metropolitan Region (SPMR). The elements Br, Co, Cs, Cu, Fe, K, Mg, Mn, Na, Rb, Se and Zn were determined by using Instrumental Neutron Activation Analysis (INAA) and Cd and Hg by Atomic Absorption Spectrometry (AAS). Arithmetic means and standard deviations of element concentrations of the results obtained in each year were calculated for the samples collected in each year. Analysis of variance (ANOVA; α = 0.05) followed by Kruskal Wallis test was applied to examine if there are temporal differences in the element mean concentrations over time. In general, significant differences of element concentrations were not obtained. However, an increase in Cd and Mn concentrations in the recent years was observed which may indicate recent increase to these elements in environment. The preliminary data obtained suggests the continuation of this kind of study to better understand the temporal trends of trace elements in the aquatic environment of SPMR. (author)

  14. Geologic studies on the Rio Una region (Iguape - Sao Paulo County), Brazil, for the construction of nuclear power plants

    International Nuclear Information System (INIS)

    The main objective of the project was the geological and seismological characterization of 230 Km2 along the coastal region between the Barro Branco and Jureia massifs in order to pinpoint one or more local areas showing adequate geological, morphological and geotechnical conditions suitable for construction of nuclear power plants. Results of the investigations, as well as the methodology used for determination of main interesting areas are presented. The best areas for construction are believed to be situated along the coast where Precambrian basement rocks crop out close to the shoreline. The Tertiary-Quaternary sedimentary cover reaches a thickness of 50 or more meters and the character of the sediments does not allow direct emplacement of foundations for heavy-weight constructions. Historical analysis of seismic activity of the region, as well as the study of faults and fracture zones identified in the area demonstrate the absence of active faults such as defined by internationally accepted safety criteria.

    The work had the purpose of checking the agricultural development processing, under the energetic view. The analysis elaborated through homogeneous micro-regions, is provided by agrocatle census from IBGE and SEADE from 1970 to 1985. The intensive use of chemical fertilizers in the seventies was encouraged by the facilities of the rural credit. The reduction of these facilities, made the use of organic fertilizers raise where, in 1985, the mature stage, more than 95% of the properties were using it. The diesel oil was the unique energetic source that showed a raise in numbers of properties as in consumed volume, showing during these period a raise of 632,59%, in Jau region, followed by gas and alcohol, representing 80% of the consumed energy. There was an electrification in the country, and in 1985, 60% of the properties were electrified. The residential was the biggest responsible for the demand of energy in the agricultural micro-regions and, for the agro-industrialized ones, it was more used in production. The period is characterized by raising the numbers of 100 HP power higher in all regions, mostly in the agro-industrialized ones, showing its operational efficiency in the field. The rough transformation that was inflicted to the agriculture, made the mechanisms unable for the agriculture development in a harmonic and proper way, making it self an appendix to the capitalist system, incorporating its way manage, becoming highly dependent on the energetic national headquarters.

    This study examines the characteristics of the water from the upper Tiete, as an input in the form of drinking water produced in eight stations, water treatment plant (WTP), an input for hydropower generation and wastewater generated by different anthropogenic activities. The most important problem of this basin is the wastewater that is released in the Pinheiros river and due to the deficit of 32.41 m3/s (2008) in the treatment of sewage in the metropolitan region of Sao Paulo ('RMSP') which produces one pollutant load of 920 thousand kilograms of BOD per day. The Pinheiros river's flow during the floods and drought has the same destination, the Billings reservoir. However, the legislation for floods and drought periods are different. The first case - floods occurs by the action of full control of the metropolitan region and is supported by the Joint Resolution of Secretaries of State of Sao Paulo (SEE-SMA-SRHSO on 13/03/96) that allows the pumping of water in the following emergencies: (1) estimates of flow of the Tiete river at the point of its confluence with the river Pinheiros, above 160 m3/ s; (2) raised level above 30 cm water level at the confluence with the river Pinheiros. The second case - drought, the Metropolitan Company for Water and Energy (EMAE) Project proposed flotation of the Secretary of State for the Environment (SMA, 2004) to treat 10 m3/ s water originating channel Pinheiros (set/2007 the set / 2008) by means of flotation technology in flow. Using information based on Environmental Sanitation Great Sao Paulo (SANEGRAN) and data from the operation of the prototype flotation system Pinheiros-Billings (Project QAPB), concluded that the environmental impact of the reservoir Billings for the load of pollutants (mass per second) pumped after the flotation of the Pinheiros river water was always lower than that observed in the flood control operation. The treatment presented by flotation removal of 91% for total phosphorus, 90% for E

    The objective of this study is to assess the climate projections over South America using the Eta-CPTEC regional model driven by four members of an ensemble of the Met Office Hadley Centre Global Coupled climate model HadCM3. The global model ensemble was run over the twenty-first century according to the SRES A1B emissions scenario, but with each member having a different climate sensitivity. The four members selected to drive the Eta-CPTEC model span the sensitivity range in the global model ensemble. The Eta-CPTEC model nested in these lateral boundary conditions was configured with a 40-km grid size and was run over 1961-1990 to represent baseline climate, and 2011-2100 to simulate possible future changes. Results presented here focus on austral summer and winter climate of 2011-2040, 2041-2070 and 2071-2100 periods, for South America and for three major river basins in Brazil. Projections of changes in upper and low-level circulation and the mean sea level pressure (SLP) fields simulate a pattern of weakening of the tropical circulation and strengthening of the subtropical circulation, marked by intensification at the surface of the Chaco Low and the subtropical highs. Strong warming (4-6 C) of continental South America increases the temperature gradient between continental South America and the South Atlantic. This leads to stronger SLP gradients between continent and oceans, and to changes in moisture transport and rainfall. Large rainfall reductions are simulated in Amazonia and Northeast Brazil (reaching up to 40%), and rainfall increases around the northern coast of Peru and Ecuador and in southeastern South America, reaching up to 30% in northern Argentina. All changes are more intense after 2040. The Precipitation-Evaporation (P-E) difference in the A1B downscaled scenario suggest water deficits and river runoff reductions in the eastern Amazon and Sao Francisco Basin, making these regions susceptible to drier conditions and droughts in the future

    Sao Luiz do Paaitinga, a city of Sao Paulo, Brazil, is considered a cultural and historical heritage of the country. On January first, of 2010 the city was hit by a devasting flood which resulted in the loss and destruction of historical and public buildings, monuments and houses. The referred places suffered damage in their structure and loss of physical and electronic documents. Most of the population lost its legal identity. The nucleo de Conservacao do Arquivo Publico do Estado de Sao Paulo - Nucleus for Conservation of public files of Sao Paulo- APESP and the Nucleo de Conservacao e Restauro Edson Motta, laboratory from National Service for Industrial Apprenticeship, became associated in order to save the documents. the access to the documents was only autorized 26 days after the flooding due to bureaucratic reasons. With few economic ressources and no time to come up with a big plan but only necessary practical courses of action, a completely manual method was established to recover this documents, with the exception of the third allotment. It had to be submitted to gamma-rays cobalt-60 from a multi purpose compact type irradiator from the Centro de Tecnologia das radiacoes do Instituto de Pesquisas Energeticas e Nucleares due to enormous fungus infection. Describing the methodology applied to recover all documents and comparing the third allotment with the others which did not receive irradiation, are the purpose of this paper.

    The Jacurici Complex, located in the NE of the Sao Francisco Craton, is constituted by several Cr-mineralized mafic-ultramafic N-S bodies, possible fragments of a single sill disrupted during deformation. Some works suggest it is intruded on the Serrinha Block while others consider it in the Salvador-Curaca Belt. The basement on this region is informally divided into paragneisses and orthogneisses; the latter is supposed to be younger considering it is less deformed. Petrography revealed that some of the paragneisses are alkali-feldspar granite strongly milonitized. The orthogneisses occur at the north and consist, at least in part, of monzogranites with heterogeneous deformation, locally of low temperature. U-Pb zircon dating were performed for five representative samples. Just three provided good concordia ages. A mafic rock produced a 2102 ± 5 Ma age and it is petrographically similar to the metanorites described in the Jacurici Complex, being interpreted as the record of the first pulses of the mafic magmatism. A monzogranite yielded a 2995 ± 15 Ma age, older than expected, related to the Serrinha Block. The alkali-feldspar granite yielded a 2081 ± 3 Ma age. The Itiuba Syenite and the pegmatites that crosscut the Jacurici Complex have similar ages. Considering the lack of information about the supracrustal sequence that hosts the intrusive alkaline and mafic-ultramafic rocks at the Ipueira and the Medrado areas, it is possible that part of the terrain belongs to the Salvador-Curaca Belt. We suggest that the Jacurici Complex could be intruded after the tectonic amalgamation between the Serrinha Block and the older part of the Salvador-Curaca Belt and, therefore, could be hosted by both terrains.

  2. Analysis of technical feasibility, economic and environmental operation of the lift system Tiete-Billings in the supply of water and electricity in the metropolitan region of Sao Paulo

    International Nuclear Information System (INIS)

    This study examines the characteristics of the water from the upper Tiete, as an input in the form of drinking water produced in eight stations, water treatment plant (WTP), an input for hydropower generation and wastewater generated by different anthropogenic activities. The most important problem of this basin is the wastewater that is released in the Pinheiros river and due to the deficit of 32.41 m3/s (2008) in the treatment of sewage in the metropolitan region of Sao Paulo ('RMSP') which produces one pollutant load of 920 thousand kilograms of BOD per day. The Pinheiros river's flow during the floods and drought has the same destination, the Billings reservoir. However, the legislation for floods and drought periods are different. The first case - floods occurs by the action of full control of the metropolitan region and is supported by the Joint Resolution of Secretaries of State of Sao Paulo (SEE-SMA-SRHSO on 13/03/96) that allows the pumping of water in the following emergencies: (1) estimates of flow of the Tiete river at the point of its confluence with the river Pinheiros, above 160 m3/ s; (2) raised level above 30 cm water level at the confluence with the river Pinheiros. The second case - drought, the Metropolitan Company for Water and Energy (EMAE) Project proposed flotation of the Secretary of State for the Environment (SMA, 2004) to treat 10 m3/ s water originating channel Pinheiros (set/2007 the set / 2008) by means of flotation technology in flow. Using information based on Environmental Sanitation Great Sao Paulo (SANEGRAN) and data from the operation of the prototype flotation system Pinheiros-Billings (Project QAPB), concluded that the environmental impact of the reservoir Billings for the load of pollutants (mass per second) pumped after the flotation of the Pinheiros river water was always lower than that observed in the flood control operation. The treatment presented by flotation removal of 91% for total phosphorus, 90% for E. coli, 53% for

    This paper presents an attempt to reconstruct vegetation and climate changes in the Jaguariuna and Botucatu regions (state of Sao Paulo, southeast of Brazil) during the late Pleistocene and Holocene, based on {sigma}{sup 13} C values of soil organic matter (SOM), {sup 14} C dating and analysis of charcoal present in the soil profiles. Sampling sites were located under natural vegetation (cerradao), along the slopes of small hills. charcoal was found predominantly between 50 and 150 cm deep, indicating a period of greater frequency of fires in this area, between 3000 and 6000 years BP. The presence of charcoal on tops of the hills suggests that sedimentation could not be the major process responsible for burying the charcoal within the soil. Biological activity (termites, ants, earthworms) played an important role in this process. For Jaguariuna site, more enriched values of {sigma}{sup 13} C of SOM were observed from the late Pleistocene until mid Holocene, indicating drier climate when compared with present-day conditions. For Botucatu site, the {sigma}{sup 13} C profile suggests predominance of C{sub 3} vegetation during the entire Holocene. (author)

    Remote sensing methods applied to geologically complex areas, through interaction of ground truth and information obtained from multispectral LANDSAT images and radar mosaics were evaluated. The test area covers parts of Minos Gerais, Rio De Janeiro and Sao Paulo states and contains the alkaline complex of Itatiaia and surrounding Precambrian terrains. Geological and structural mapping was satisfactory; however, lithological varieties which form the massif's could not be identified. Photogeological lineaments were mapped, some of which represent the boundaries of stratigraphic units. Automatic processing was used to classify sedimentary areas, which includes the talus deposits of the alkaline massifs.

    International Nuclear Information System (INIS)

    Complete text of publication follows. More than 10 years (1998-2008) of data from a low latitude station, Gadanki, India (13.5deg N, 79.2deg E), has been utilized to measure middle atmospheric temperature pattern, using lidar and TIMED/SABER, which exhibits the presence of semi-annual oscillation (SAO) and annual oscillation (AO). AO component is stronger in mesospheric region (80-90 km) and SAO is dominant at stratospheric altitudes (30-50 km). Overall, AO possesses higher amplitude ∼ 6 K, and SAO shows relatively less amplitude ∼ 1-2 K. AO at 90 km, has its crest around summer solstice, and the same at 80 shows peak around winter solstice with a downward progression speed ∼ 1.67 km/month. SAO propagates downward with an average phase speed ∼ 7 km/month and its phase maximizes around equinox and solstice at 50 and 30 km, respectively. Observed SAO has also shown seasonal asymmetry in the peak.

    As part of a project which aims metal concentration assessment in urban park soils of Sao Paulo, in the present paper the concentration of the elements As, Ba, Cr, Co, Cu, Pb, Sb and Zn were determined in surface soil samples (0-5 cm and 0-20 cm) from Buenos Aires park of Sao Paulo. This park is located in central region of the city, and is surrounded by avenues and streets, with different traffic volumes. Instrumental Neutron Activation Analysis (INAA) and X-ray Fluorescence (FRX) were used for metal analysis. Preliminary results showed concentration levels of the analyzed elements higher than the values considered as reference values for soils in Sao Paulo, according to the Environmental Protection Agency of the State of Sao Paulo (CETESB). These results suggest that these elements have anthropogenic origin and indicate a potential risk for soil quality. (author)

    Objective To know the characteristics of contraceptive use in Sao Paulo State collected by the Demographic and Health Survey (DHS) conducted in 1996.Methods Data of Sao Paulo in 1996 were analyzed compared with the previous DHS carried on in 1986focusing on Sao Paulo State. Contraceptive use among married or cohabiting women by age, number of children and schooling was closely examined.Age and timing of female sterilization were also analyzed.Results The results showed that unlike Brazil there was a stability of female sterilization in Sao Paulo State during 1986 and 1996. There was a pattern in Sao Paulo: up to 30years old the pill was the most used contraceptive, after 30 there was a predominance of female sterilization, which increased with the number of children and decreased with schooling. The use of male methods had also increased in the 1986 and 1996period, being greater in Sao Paulo than in Brazil. Sao Paulo also presented more diversity in the use of reversible contraceptives.Conclusions The predominant two contraceptive methods in Brazil and Sao Paulo changed from 1986 to 1996, I.e. From pill to female sterilization.

  14. Metal and trace element sediment assessment from two estuarine systems: Santos/Sao Vicente and Cananeia, State of Sao Paulo, Brazil

    International Nuclear Information System (INIS)

    This study evaluated some toxic metals such as Cd, Hg and Pb and some other major and trace elements in surface sediment samples, from two different systems under different degrees of anthropogenic actions: the estuarine system of Santos/Sao Vicente and the southern part of the Cananeia estuary, both on the Sao Paulo state coast. Sediment samples were collected in 16 stations in the Santos/Sao Vicente estuary and 13 stations in the Cananeia estuary, during summer and winter of 2005 and 2006, in both estuaries. Three analytical techniques were used: NAA, AAS and ICP OES. NAA was used for the quantification of major element concentration levels (Ca, Fe and Na), trace elements (As, Ba, Br, Cd, Co, Cu, Cr, Cs, Hf, Rb, Sb, Sc, Se, Ta, Th, U, and Zn and rare earths elements La, Ce, Eu, Nd, Sm, Lu, Tb, Yb). ICP OES was used for determination of the concentration levels of Al, Ba, Be, Bi, B, Cd, Co, Pb, Cu, Cr, Sn, Sr, Fe, Li, Mn, Mo, Ni, Tl, Ti, V and Zn. AAS for Cd and Pb quantification through graphite furnace (GF AAS) and Hg through cold vapor generation (CV AAS). Methodology validation according to precision and accuracy was performed by reference material analyses for the three analytical techniques used. Detection and quantification limits were calculated for each element evaluated. Seasonal variations (summer and winter), spatial and temporal (2005 e 2006) variations of metals and trace elements were also evaluated. In the Santos estuary, in general, metal and trace element concentrations , organic matter content and % of pelitic fraction found in the Santos channel (area 1) were higher than those of the Santos Bay (area 2) and Sao Vicente channel (area 3). Area 1 suffers high impact from industrial activities from the Cubatao region and Santos port. The sediments from station 14 (area 3, Sao Vicente channel), showed the same behavior of those from area 1, suffering influence from the industrial pole and located in a mangrove area.

    The Sao Paulo Metropolitan Area (SPMA), in the southeast region of Brazil, is considered a megalopolis comprised of Sao Paulo city and more 38 municipalities. The air pollutant emissions in the SPMA are related to the burning of the fuels: etanol, gasohol (gasoline with 25% ethanol) and diesel. According to CETESB (2013), the road vehicles contributed up to about 97, 87, and 80% of CO, VOCs and NOx emissions in 2012, respectively, being most of NOx associated to diesel combustion and most of CO and VOCs from gasohol and ethanol combustion. Studies conducted on ambient air pollution in the SPMA have shown that black carbon (BC) explains 21% of mass concentration of PM2.5 compared with 40% of organic carbon (OC), 20% of sulfates, and 12% of soil dust (Andrade et al., 2012). Most of the observed ambient PM2.5 mass concentration usually originates from precursors gases such as sulphur dioxide (SO2), ammonia (NH3), nitrogen oxides (NOx) and VOCs as well as through the physico-chemical processes such as the oxidation of low volatile hydrocarbons transferring to the condensed phase (McMurry et al., 2004). The Weather Research and Forecasting with Chemistry model (WRF-Chem; Grell et al. 2005), configured with three nested grid cells: 75, 15, and 3 km, is used as photochemical modeling to describe the physico-chemical processes leading to evolution of particles number and mass size distribution from a vehicular emission model developed by the IAG-USP laboratory of Atmospheric Processes and based on statistical information of vehicular activity. The spatial and temporal distributions of emissions in the finest grid cell are based on road density products compiled by the OpenStreetMap project and measurements performed inside tunnels in the SPMA, respectively. WRF-Chem simulation with coupled primary aerosol (dust and sea-salt) and biogenic emission modules and aerosol radiative effects turned on is conducted as the baseline simulation (Case_0) to evaluate the model

  18. Uranium and thorium in urban park soils of Sao Paulo

    International Nuclear Information System (INIS)

    The Environmental Protection Agency of the State of Sao Paulo (CETESB) has reported the Quality Reference Value (VRQ) for soils in Sao Paulo, which is the concentration of a substance in the soil or groundwater which defines groundwater quality and clean soil, for several elements. Nevertheless, there is no information about U and Th concentrations. In the present paper, which is part of a main project that assesses metals in urban park soils of Sao Paulo city, the concentration of U and Th were determined in surface soil samples of fourteen city public parks. Instrumental Neutron Activation Analysis (INAA) was used for analysis. The U and Th range concentrations obtained were: 1.9 to 8.6 mg kg-1 for U and 8.4 to 38.0 mg kg-1 for Th. The U and Th range concentrations obtained are significantly higher compared to NASC values (2.7 mg kg-1 for U and 12 mg kg-1 for Th), but they are in the same order of magnitude of other studies reported in the literature. The uranium and thorium concentrations in Sao Paulo park soils may be attributed to lithology of Sao Paulo. On the other hand, high uranium concentrations (up to hundreds of ppm) have been reported in the literature in fertilizers containing phosphate, which may have contributed to the uranium levels in the park soils, due to the park garden maintenance.

    Moreno, Marcelo Baena; Muller, Carlos

    2003-01-01

    Using the conditional LOGIT model, this paper addresses the airport choice in the Sao Paulo Metropolitan Area. In this region, Guarulhos International Airport (GRU) and Congonhas Airport (CGH) compete for passengers flying to several domestic destinations. The airport choice is believed to be a result of the tradeoff passengers perform considering airport access characteristics, airline level of service characteristics and passenger experience with the analyzed airports. It was found that access time to the airports better explain the airport choice than access distance, whereas direct flight frequencies gives better explanation to the airport choice than the indirect (connections and stops) and total (direct plus indirect) flight frequencies. Out of 15 tested variables, passenger experience with the analyzed airports was the variable that best explained the airport choice in the region. Model specifications considering 1, 2 or 3 variables were tested. The model specification most adjusted to the observed data considered access time, direct flight frequencies in the travel period (morning or afternoon peak) and passenger experience with the analyzed airports. The influence of these variables was therefore analyzed across market segments according to departure airport and flight duration criteria. The choice of GRU (located neighboring Sao Paulo city) is not well explained by the rationality of access time economy and the increase of the supply of direct flight frequencies, while the choice of CGH (located inside Sao Paulo city) is. Access time was found to be more important to passengers flying shorter distances while direct flight frequencies in the travel period were more significant to those flying longer distances.

    The Guarani aquifer is one of the largest reservoirs of groundwater in the world and represents a strategic reserve for the four countries of South America where it occurs: Argentina, Brazil, Paraguay and Uruguay. The municipality of Ribeirao Preto, located in the north-east region of Sao Paulo, with a population of over 600,000 inhabitants, is supplied entirely by water from this aquifer. Hydrogeological studies reveal the existence of a large cone of drawdown in the centre of the city due to the intensive and indiscriminate use of water pumped out by wells for decades. In rural areas, where many of the rocky outcrops of the aquifer occur and which affords direct recharge by rain water, the risk of contamination by pesticides is of some concern. Over the years the Public Ministry of Sao Paulo in Ribeirao Preto has provided guidelines for actions and initiatives in environmental protection, especially with regard to the Guarani aquifer. These actions and initiatives are based mainly on the principle of the supremacy of public interest over private interest and the principle of caution. On the basis of these premises the prosecutor works with the government and the private sector to monitor and readmitted environmental liabilities that threaten the aquifer (landfills, diffuse contamination etc.) and to maintain due discipline within the activities that take place within the recharge zone (agriculture, industry and urbanization) including those of regulation and territorial planning.

    Recent developments in Fission Track thermochronology associated to mesozoic-cenozoic erosion and tectonic presented trough thematic maps (isotemperature), permit to model the landscape evolution in the southern border of the Sao Francisco craton, southeastern Brazil. Paleotemperature, obtained by fission track analysis in apatite, is closely related to geomorphologic interpretations. The area suffered a complex imprint of endogenous and exogenous processes resulting diversified and differentiated relieves. The landscape is strongly controlled by exhumation between Jurassic and Lower Cretaceous, uplift with tectonic denudation related to crustal heating at the Upper Cretaceous and reactivation of faults until the Miocene. This scenario is a result of reactivations of different brittle structures that accommodate the deformation in the southern border of the Sao Francisco craton. The landscape reflects denudations of up to 3 km with preserved remains of erosive surfaces in the topographical tops and chronocorrelates deposits in the basins of the region. (author)

    This paper aims to assess the viability of the use of distributed resources for power production inside the state of Sao Paulo, taking into account its different forms, advantages and drawbacks. To accomplish the assessment and using de integrated energy resources planning, the full cost accounting for energy resources was applied to each administrative region of the state, which allowed a greater focus without jeopardizing the final results. The analysis were performed considering the usage of the most prospective energy sources such as wind, solar, natural gas, hydro and biomass generation; the results show that when the different aspects of each type of distributed generation are taken into account the renewable forms of energy generation are likely to be more competitive, when compared to traditional forms of generation.

  9. Ionizing radiation population doses at Sao Paulo city, Brazil: open-pit gamma dose measurement

    International Nuclear Information System (INIS)

    The effects of ionizing radiation to the human beings are well known for high and intermediate doses. As far as low level) radiation doses are concerned, there is no consensus. In order to get a better understanding of such effects it is necessary to assess the low doses with better accuracy. In this work, it was made an estimate of the annual ambient dose equivalent (H*(10)) to which the people are exposed in the city of Sao Paulo. Until now there are no data about it available in the literature. For the purpose of this evaluation, a map with various routes covering the largest and more representative area of the city was designed. The choice of points for data collection was made taking into account mainly the occupancy of the region. A portable gamma spectrometry system was used. It furnishes the rate of H*(10) and the measured gamma spectrum (in the range from 50 to 1670 keV) in the place of interest. The measurements were performed in a short time interval, since the gamma radiation arrives from a great extent of soil. Each measurement was done 1 m above the soil during 300 s. The rates of H*(10) varied from 33.1 to 152.3 nSv.h-1, net values, obtained after subtraction of the cosmic rays contribution. The standard deviation was 22 n Sv.h-1 for an average for the city of Sao Paulo of 96.1(24) nSv.h-1. In addition, average values of H*(10) rates for the city Health Divisions were calculated. Those values are not statistically equivalent and the whole set of data could not be treated as one, as the statistical Student test indicated a non homogeneity of the group of data. Hence it is necessary the accomplishment of a more detailed survey in order to verify the origin of the discrepancy. The mean value of H*(10) rate obtained for the city of Sao Paulo as converted to effective dose. in order to be compared with other places results It could be noticed that the annual average of effective dose for the city of Sao Paulo, 0.522(13) mSv, is superior to the world

    Bluetongue (BT is an infectious, insect-born viral disease of ruminants. The causative agent of BT is bluetongue virus (BTV that belongs to the family Reoviridae genus Orbivirus. Insect vectors in the genus Culicoides transmit this virus. BT affects domestic and wild ruminants, however small ruminants are considered the most affected specie. The aim of the study was to detect antibodies against BTV in commercial sheep farms, of the Northeastern region of Sao Paulo State, Brazil. A total of 1002 sera samples collected from adult sheep (above 1 year-old, comprising a total of 31 farms, were screened for the presence of BTV antibodies, by agar gel immunodiffusion test (AGID and ELISA-CFS (Enzyme Linked Immunosorbent Assay – competitive solid phase, both produced by Pan American Center of FMDV. From a total of 1002 samples, 651 (65% were positive by AGID and 742 (74.1%, were positive by ELISA-CFS. These results suggest that the BTV is widespread among farms, probably causing subclinical infections.

    This aim of work is the geological and geochronological study of rocks cropping out on Cardoso Island, on the southeastern coast of Sao Paulo States, close to be boundary with Parana State. The Island with an area of about 151 km{sup 2} is a protected area administered by the Forest Institute of Environment Secretariat of the State of Sao Paulo. It is mountanious, with a peak at 814 m, and is covered by dense Mata Atlantica vegetation. The terrains which compose the island are mainly an igneous complex with light grey leucocratic, inequigranular, medium - to coarse-grained syenites. The predominant Tres Irmaos Syenite (STI), composed of pyroxene, hornblende, and perthitic to mesoperthitic microcline, has a magmatic flow structures, and is cut by the Cambriu alkali-feldspar Granites (GC), which is pinkish grey, leucocratic and medium-grained. Geochemical analysis of STI and GC demonstrate their meta luminous alkaline nature and late-orogenic to an orogenic character. The geochronological results suggest that the bodies were formed between 620 and 570 My according to the U-Pb method in zircons, with cooling between 597 and 531 My (K-Ar in amphiboles). Whole rock Sm-Nd analysis yield T{sub DM} ages in the Meso and Paleoproterozoic (1.200 - 2.200 My). belt of low grade meta sedimentary rocks occurs in the northern part of the island. Quartz schist, quartz-mica schist and mica-quartz schist, often containing andaluzite and cordierite, predominate. The geochemical and geochronological data suggest that the sources of the metasediments were andesites of continental arc whose protolities separated from the mantle during the Paleoproterozoic, between 1.800 and 2.200 My. These metasediments probably continue on the continent in the Taquari region and extend southwards in narrow strips between the granitoids of the Paranagua Domain. Although quaternary deposits are expressive, they were not studied in details since they were not the objectives of this study. (author)

    A 16 station array was operated over the 200 km**2 central portion of Sao Miguel utilizing 8 permanent Instituto Nacional de Meterologia e Geofisica stations and 8 USGS portable stations. Forty four local events with well constrained solutions and 15 regional events were located. In addition, hundreds of unlocatable seismic events were recorded. The most interesting seismic activity occurred in a swarm on September 6 and 7, 1983 when over 200 events were recorded in a 16 hour period. The seismic activity around Agua de Pau was centered on the east and northeast slopes of the volcano. The data suggest a boiling hydrothermal system beneath the Agua de Pau volcano, consistent with a variety of other data.

    Geothermal studies were carried out on the island of Sao Miguel, Azores to characterize the nature of the resource, to estimate its magnitude, and to identify target areas toward which exploration and developmental drilling might be directed. The main geothermal resource areas are Furnas, Agua de Pau, and Sete Cidades, three Quaternary silicic volcanic centers characterized by summit calderas beneath which magmatic heat sources provide thermal energy to overlying hydrothermal convection systems. For each of the systems, the studies have defined the size of the system, the subsurface temperature, the thermodynamic state of fluid in the system, the chemical composition of the fluid, and permeable parts of the system. 8 figs.

    Deuteron elastic and inelastic scattering from 6Li, 12C, 16O, 24Mg, 32S, 50V, 58Ni, 70Ge, 90Zr, and 116Sn targets at different incident energies have been analyzed. Both Phenomenological Woods-Saxon and double-folding optical model potentials have been used. The folding calculations were based upon the Sao Paulo potential. A semi-microscopic representation has been proposed to study the effect of the dynamic polarization potential. Comparisons between our results and measured angular distributions of the differential cross sections showed a pronounced success of our theoretical predictions. The corresponding reaction cross sections have also been investigated.

  16. Natural radionuclides in soils from Sao Paulo State cerrado forest

    International Nuclear Information System (INIS)

    Considering the long life history, forests should be preferentially evaluated for the monitoring of radionuclides, mainly artificial radioisotopes. However, little is known about nuclides from Uranium and Thorium series, as well as, K-40, in soils from the Sao Paulo State forests. Soils are the main reservoir of natural radionuclides for vegetation, thereby deserving attention. Taking into account the advantages of High-Resolution Gamma-ray Spectrometry (HRGS), diverse radionuclides can be quantified simultaneously. In this work natural radionuclides in soils from the Estacao Ecologica de Assis were evaluated by HRGS. Samples of 0-10 cm depth were collected under crown projection of most abundant tree species of long-term plots installed within the Estacao Ecologica de Assis, Sao Paulo State, Brazil. After drying and milling until 0.5 mm particle size, test portions of 30 g were transferred to polypropylene vials, sealed with silicone and kept under controlled conditions until 30 days to achieve secular equilibrium. A group of gamma-ray spectrometers was used to analyze about 27 samples by 80,000 seconds. Activity concentrations of Pb-214, Ac-228 and K-40 and their respective expanded analytical uncertainties at the 95% confidence level were calculated by Genie software from Canberra. Abnormal values were not detected for radionuclides in soils samples, however K-40 activity concentrations changed considerably due to the mineral cycling, in which K and, consequently K-40, is mainly stocked in vegetation in spite of soils.

    Our aim is investigating surface inhomogeneities of the young late-type star SAO51891, from photosphere to upper chromosphere, analyzing contemporaneous high-resolution spectra and broad-band photometry. The FOCES@CAHA spectral range is used to determine spectral classification and derive vsini and Vrad. The Li abundance is measured to estimate the age. The BVRIJHKs bands are used to construct the SED. The variations of our BV fluxes and Teff are used to infer the presence of photospheric spots and observe their behavior over time. The chromospheric activity is studied applying the spectral subtraction technique to Halpha, CaII H&K, Heps, and CaII IRT lines. We find SAO51891 to be a young K0-1V star with Li abundance close to the Pleiades upper envelope, confirming its youth (~100 Myr), also inferred from its kinematical membership to the Local Association. We detect no IR excess from SED analysis, and rotational modulation of luminosity, Teff, CaII, and Heps total fluxes. A spot model with two active reg...

    Full Text Available Abstract Background Age-related gene expression patterns of Homo sapiens as well as of model organisms such as Mus musculus, Saccharomyces cerevisiae, Caenorhabditis elegans and Drosophila melanogaster are a basis for understanding the genetic mechanisms of ageing. For an effective analysis and interpretation of expression profiles it is necessary to store and manage huge amounts of data in an organized way, so that these data can be accessed and processed easily. Description GiSAO.db (Genes involved in senescence, apoptosis and oxidative stress database is a web-based database system for storing and retrieving ageing-related experimental data. Expression data of genes and miRNAs, annotation data like gene identifiers and GO terms, orthologs data and data of follow-up experiments are stored in the database. A user-friendly web application provides access to the stored data. KEGG pathways were incorporated and links to external databases augment the information in GiSAO.db. Search functions facilitate retrieval of data which can also be exported for further processing. Conclusions We have developed a centralized database that is very well suited for the management of data for ageing research. The database can be accessed at https://gisao.genome.tugraz.at and all the stored data can be viewed with a guest account.

  20. Physicochemical characterization of ceramics from Sao Paulo II archaeological site

    International Nuclear Information System (INIS)

    Archaeometry is a consolidated field with a wide application of nuclear analytical techniques for the characterization, protection, and restoration of archaeological pieces. This project aimed at studying the elementary chemical composition of 70 ceramic fragments samples from Sao Paulo II archaeological site, located along the Solimoes River channel, next to Coari city, in Brazilian Amazon. The characterization of samples was performed by neutron activation analysis (NAA). By the determination of 24 elements in the ceramic fragments ( Ce, Co, Cr, Cs, Eu, Fe, Hf, K, La, Lu, Na, Nd, Sb, Sm. Rb, Se, Ta, Tb, Th, U, Yb and Zn), it was possible to define groups of samples regarding the similarity/dissimilarity in elementary chemical composition. For such a task, the multivariate statistical methods employed were cluster analysis (C A), principal component analysis (PCA) and discriminant analysis (DA). Afterwards, seven ceramic fragments were selected based on the groups previously established, for the characterization of the site temporal horizon. Those ceramic fragments were analyzed by thermoluminescence (TL) and EPR for dating purposes. The firing temperatures were determined by electron paramagnetic resonance (EPR) technique, in order to infer about some aspects of the ceramic manufacture employed by the ancient peoples that lived in Sao Paulo 11. By the results obtained in this study, it was possible to identify the quantity of clay sources employed by the ceramists and the age of the ceramic pieces. Therefore, the results of this research may contribute to the study on the occupation dynamics in the pre-colonial Brazilian Amazon. (author)

    The Salto Grande Reservoir is used for electric generation, irrigation, fish farming, recreation and water supply for the region's cities. The reservoir belongs to the city of Americana, located in on the eastern region of Sao Paulo State, Brazil. It belongs to the Piracicaba River Hydrographic Basin, the second most important economic and populated region and one of the most polluted areas in the State. This basin is located in a highly industrialized and agricultural region. Due to urban, industrial and agricultural activities as well as sewage wastes the water and sediments of this reservoir and surroundings are extremely contaminated, mainly by metals, according to CETESB (Environmental Control Agency of the Sao Paulo State). In order to obtain better information about its sediment contamination the present study reports results of the concentration of some major (Ca, Fe, K and Na), trace (As, Ba, Br, Co, Cr, Cs, Hf, Rb, Sb, Se, Ta, Th, U, Zn and rare earth (Ce, Eu, La, Lu, Nd, Sc, Sm, Tb and Yb)) elements in sediments and Cd, Cr, Cu, Ni and Pb concentration in sediments and water from the Salto Grande Reservoir. Multielementar analysis was carried out by Instrumental Neutron Activation Analysis (INAA). Multielemental concentrations in the sediment samples were compared to NASC (North American Shale Composite) values.

    Results and perspectives of the Geoelectrical Resistivity Sounding Survey in Eastern Baixada Fluminense, Rio de Janeiro State, run by DEGEO/IA/UFRRJ (Rural University of Rio de Janeiro, Agronomy Institute, Geology Dept.) for the Municipal Prefecture of Araruama in Sao Vicente District, RJ, where underground is needed to support irrigation projects, mainly of citrus, are presented. Geophysical data interpretation resulted in a 900 m long geoelectrical cross section illustrating that groundwater subsurface conditions in the surveyed area comprise: the 1400-1800 ohm.m resistivimetric regions associated to the granitic-gneissic embasement`s fracturing/faulting zones; the 215 ohm.m resistivimetric region associated to the embasement`s type C weathering horizon; and all others resistivimetric regions, below the water table, ranging from 27-227 phm.m, associated to an averaging 35 m thick and course sedimentary package overlaying the crystalline. Finally it is possible to conclude that groundwater in Sao Vicente, District of Araruama, RJ, must not be considered a possibility.

    Full Text Available WNT5A is a secreted ligand involved in Wnt pathway signaling and has a role in cell movement and differentiation. Altered WNT5A expression is associated with various cancers, although in most studies the focus has been on only one of the known WNT5A isoforms. In this study, we analyzed expression from two of the major WNT5A promoters, termed promoter A and promoter B, in normal human osteoblasts, SaOS-2 and U2OS osteosarcoma cell lines, and osteosarcoma tumor tissue. We found that both promoters A and B are active in normal osteoblasts with nearly 11-fold more promoter B than A transcripts. Promoter B but not promoter A transcripts are decreased or nearly undetectable in the SaOS-2 and U2OS cell lines and osteosarcoma tumor tissues. Transient transfection of promoter A and promoter B reporter constructs confirmed that SaOS-2 cells have the necessary factors to transcribe both promoters. Bisulfite sequencing analysis revealed that three CpG enriched regions upstream of the promoter B exon 1βare highly methylated in both SaOS-2 and U2OS cells. The CpG island sub-region R6 located in promoter B exon 1β was approximately 51% methylated in SaOS-2 and 25% methylated in U2OS. Region 3 was approximately 28% methylated in normal osteoblasts, whereas the others were unmethylated. Promoter B was re-activated by treatment of SaOS-2 cells with 1 μM 5-azacytidine, which was associated with only a small insignificant change in methylation of sub-region R6. ChIP analysis of U2OS and SaOS-2 cells indicated that the promoter B region is less enriched in the active histone mark H3K4me3, in comparison to promoter A and that there is increased enrichment of the repressive mark H3K27me3 in association with the promoter B genomic region in the cell line SaOS-2. These findings show that epigenetic inactivation of the WNT5A promoter B involves both DNA methylation and histone modifications and suggest that differential expression of the WNT5A alternative promoters A

    The phenomena called acid rain is considered, by many researchers, one of the most serious environmental problem. This work has the aim of showing, in a theoretical and practical study, the problems caused by the atmospheric-pollutant emission, through natural or anthropogenic sources. In a period of 1 year (nov/94-nov/95), it was realized a practical work on rainwater, which consisted of collecting and, afterwards, analysing some physical and chemical parameters of this water, such as acidity, ionic concentrations, etc, with the purpose of characterizing the rainwater in Cidade Universitaria (SP, Brazil). After ending the practical part, it was possible to observe a 1,236.71 mm/y pluviosity, characterized by rainy summer and dry winter. The chemical-constituent-concentration analysis show us the predominance of SO{sup 2-}{sub 4} and Ca{sup 2+}, and a continental-origin water). The region of sao Paulo (Brazil), site of this study, is one of the largest metropolitan and industrialized areas of the world, which includes 18 million people, beside to an enormous industrial and vehicular complex. The acidity in the rain water is a complex problem and it must be treated by a range of disciplines to have a better comprehension of the cause/effects of the acid rain.

  9. Early experience of the SAO Satellite-Tracking Program

    Science.gov (United States)

    Pearlman, M. R.

    When Fred L. Whipple of Harvard University assumed the directorship of the Smithsonian Astrophysical Observatory (SAO) in mid-1955, he proposed to the National Academy of Sciences and the National Science Foundation that the observatory be given responsibility for optical tracking of satellites during the IGY of 1957-1958. Several countries had expressed their intentions to launch satellites during the 18-month period to support research in ionospheric and upper atmospheric physics, including the effects of solar flares and solar radiation, and in geodesy and geophysics. On the basis of his experience at the Harvard College observatory with the Super-Schmidt cameras for meteor photography, Whipple was confident that optical tracking could provide a powerful means of monitoring satellite positions. The proposal was accepted in late 1955, and it was assumed that the total observing program would last only 18 months and would involve only a few satellites.

    We present an extension for the 2D (zonal mean) version of our Numerical Spectral Mode (NSM) that incorporates Hines' Doppler spread parameterization (DSP) for small scale gravity waves (GW). This model is applied to describe the seasonal variations and the semi-annual and quasi-biennial oscillations (SAO and QBO). Our earlier model reproduced the salient features of the mean zonal circulation in the middle atmosphere, including the QBO extension into the upper mesosphere inferred from UARS measurements. In the present model we incorporate also tropospheric heating to reproduce the upwelling at equatorial latitudes associated with the Brewer-Dobson circulation that affects significantly the dynamics of the stratosphere as Dunkerton had pointed out. Upward vertical winds increase the period of the QBO observed from the ground. To compensate for that, one needs to increase the eddy diffusivity and the GW momentum flux, bringing the latter closer to values recommended in the DSP. The QBO period in the model is 30 months (mo), which is conducive to synchronize this oscillation with the seasonal cycle of solar forcing. Multi-year interannual oscillations are generated through wave filtering by the solar driven annual oscillation in the zonal circulation. Quadratic non-linearities generate interseasonal variations to produce a complicated pattern of variability associated with the QBO. The computed temperature amplitudes for the SAO and QBO are in substantial agreement with observations at equatorial and extratropical latitudes. At high latitudes, however, the observed QBO amplitudes are significantly larger, which may be a signature of propagating planetary waves not included in the present model. The assumption of hydrostatic equilibrium not being imposed, we find that the effects from the vertical Coriolis force associated with the equatorial oscillations are large for the vertical winds and significant for the temperature variations even outside the tropics but are

    International Nuclear Information System (INIS)

    In the present study instrumental neutron activation analysis has been applied to determine the elements accumulated in samples of Canoparmelia texana, a specie of lichen, collected in regions with different levels of pollution: Intervales State Park, an area considered non polluted that belongs to Atlantic Forest ecosystem and distinct sites in the metropolitan region of Sao Paulo city. The results obtained in the analysis showed that samples collected in the clean area indicated lower concentrations of elements than those obtained for samples from metropolitan region. The concentrations of the elements Ba, Ca, Cl, Fe, K, Mn, Na, Rb and Zn were obtained at μg g-1 levels and the elements As, Br, Co, Cr, Cs, La, Sb, Sc, Se and U at ng g-1 levels. Cluster analysis was applied to classify into distinct groups the sites using the element concentrations in these samples. The accuracy and precision of the results were evaluated by IAEA 336 Lichen reference material analysis and the data given for this material were in agreement with certified values with relative standard deviations lower than 11,4%.

    Capelinha is a fluvial sambaqui (Brazilian Shell Mound) located in the Ribeira Valley in the State of Sao Paulo that is being studied. It is one of the oldest sambaquis located along a river dated so far in this region. The use of ESR to date other shells stimulated our group to apply this method to the Capelinha site. Shells from land snails (Megalobulimus sp.) obtained in two levels of excavations were analyzed; one of them was in contact with a skeleton that was dated by C-14. The archaeological doses obtained were (8.05{+-}0.07) Gy and (9.50{+-}0.03) Gy. Since the last site was previously dated by C-14 (Beta -Analytics, Beta 153988) giving: 8860 +/- 60 years BP (conventional age) and 10180 to 9710 years BP (calibrated age), the archaeological dose found for this shell was used to determine the local rate of (0.93 to 0.98) mGy/year, that aggress with other surveys done in the region. Using this dose rate the age of the second shell was found to be 8.14 to 8.73 ky BP that agrees with the stratigraphy of the site. (author)

    Eleven years of lightning data from the Brazilian Integrated National Lightning Detection Network were used to analyze the effects of the urban heat island (UHI) of Sao Paulo on lightning activity, extending the investigation of previous works. Cloud-to-ground lightning data were analyzed in both spatial and temporal perspectives, using different approaches: flash density, flash rate, thunderstorm hours (TH), and the cell initiation technique (CIT), which aims to identify the onset of thunderstorms. Land surface temperature (LST) from MODIS (Moderate Resolution Imaging Spectroradiometer) was used to analyze the UHI evolution over the years. MODIS data were validated using ground stations, distributed within the urban area. Different time intervals (seasonal and intraday) were used in an attempt to separate local convective systems from synoptic-scale events. The results indicate significant effects of the UHI (using LST) on THs and CIT. The CIT showed a nearly ring pattern, especially during the afternoon (14:00-18:00 LT) of summer months, reinforcing temperature contrast as a condition for storm initiation. The results also suggest an amplification of the UHI effects on thunderstorm activity by local factors (sea and country breeze, synoptic events, and terrain). Higher flash rates were also observed throughout the urban region, which influences the lightning density. Temporal analysis indicates that minimum temperature and lightning activity increase in wintertime. In summary, the results agree with previous studies about the UHI and indicate its importance on lightning occurrence, especially by increasing the temperature contrast and the instability in these regions.

    Landsat satellite images and agrometeorological data were used together for modelling the crop coefficient (Kc) in irrigation pivots composed by a mixture of corn hybrids from a commercial farm for grains and silage, located at the northwestern side of Sao Paulo state, Brazil. After developing relationships between Kc and the accumulated degree-days (DDac) and having yield data for 2012 available, they were applied in the whole state, to upscale the crop water variables, during the GS (growing seasons) of a second-harvest crop from March to August. Spatial thermohydrological differences among the main corn growing regions were clear. The largest CWP (crop water productivity) values and SD (standard deviations) were for Itapetininga with an average value of 1.60 ± 0.43 kg m-3, while the lowest ones were for Presidente Prudente (0.81±0.21 kg m-3). As corn is important for these growing regions, being inside of the priorities from the Brazilian Ministry of Agriculture, these results should be considered for a rational exploration, including both, irrigation and rainfed conditions, as the actual water scarcity can bring much competition with other non-agricultural sectors.

    Full Text Available Vehicular emissions have a strong impact on air pollution in big cities. Many factors affect these emissions: type of vehicle, type of fuel, cruising velocity, and brake use. This study focused on emissions of organic compounds by Light (LDV and Heavy (HDV duty vehicle exhaust. The study was performed in the city of Sao Paulo, Brazil, where vehicles run on different fuels: gasoline with 25 % ethanol (called gasohol, hydrated ethanol, and diesel (with 5 % of biodiesel. The vehicular emissions are an important source of pollutants and the principal contribution to fine particulate matter (smaller than 2.5 μm, PM2.5 in Sao Paulo. The experiments were performed in two tunnels: Janio Quadros (TJQ where 99 % of the vehicles are LDV, and Rodoanel Mario Covas (TRA where up to 30 % of the fleet was HDV. The PM2.5 samples were collected on quartz filters in May and July 2011 at TJQ and TRA, respectively, using two samplers operating in parallel. The samples were analyzed by Thermal-Desorption Proton-Transfer-Reaction Mass-Spectrometry (TD-PTR-MS, and by Thermal-Optical Transmittance (TOT. The organic aerosol (OA desorbed at TD-PTR-MS represented around 30 % of the OA estimated by the TOT method, mainly due to the different desorption temperatures, with a maximum of 870 and 350 °C for TOT and TD-PTR-MS, respectively. Average emission factors (EF organic aerosol (OA and organic carbon (OC were calculated for HDV and LDV fleet. We found that HDV emitted more OA and OC than LDV, and that OC emissions represented 36 and 43 % of total PM2.5 emissions from LDV and HDV, respectively. More than 700 ions were identified by TD-PTR-MS and the EF profiles obtained from HDV and LDV exhibited distinct features. Nitrogen-containing compounds measured in the desorbed material up to 350 °C contributed around 20 % to the EF values for both types of vehicles, possibly associated with incomplete fuel burning.

  2. Preliminary analysis on the disposal of high-level radioactive wastes in geological formations of Sao Paulo state, Brazil

    International Nuclear Information System (INIS)

    Several studies show that deep geological formations are the most promising solution - technical and economical - for the safe disposal of the high-level radioactive wastes produced by the nuclear industry. In order to obtain the necessary information to assess on the use of geological sites in Brazil - for the disposal of high-level radioactive waste generated by the brazilian nuclear industry - a careful survey on the basalt and granite rocks of Sao Paulo State was made. The data obtained were evaluated according to guidelines established by the International Atomic Energy Agency. The favourable and unfavourable characteristics of the basalts, granites and their respective occurrence areas in the Sao Paulo state territory - as potential waste disposal sites - were analysed. This preliminary and regional characterization is not a conclusive study whether these two rocks types are definitively the most suitable geological formations for use as nuclear waste repository or not. It is the subsidy for a more detailed analysis. Other factors such as social, political and economical aspects, ecological effects, engineering geology, heat generation rate of the waste, type of radiation emitted and corrosive nature of the waste must also be taken into account.

    Jardim, Maria Dolores Rodrigues

    This qualitative bounded case study was designed to understand how technology integration in schools could be addressed in a first-wave country. The integration of educational technology in Sao Tome and Principe (STP), a first-wave agricultural civilization, can narrow the divide between STP and third-wave information age societies. The conceptual framework was based on theories of change, learning, and context. Toffler's wave theory described how societies changed while Fullan's change theory examined how the people might change. Roger's diffusion of innovations addressed how processes change. Bandura, Vygotsky, and Siemen provided the framework for the learning within the model of change. Finally, the context theories of Tessmer and Richey's instructional design, Lave and Wenger's situated learning, and Sticht's functional context theory were applied. Twenty five individuals from 5 schools, including teachers, school directors, key educational stakeholders, and the minister of education were involved in a pilot project to integrate technology into the science curriculum. The data were collected via interviews, reflective summaries, and confidential narratives. The resulting data were analyzed to find emerging patterns. The results of this analysis showed that a first-wave civilization can adopt a third-wave civilization's features in terms of technology integration, when there is the support of opinion leaders and most of the necessary contextual requirements are in place. The study contributes to social change by providing access to knowledge through technology integration, which empowers both teachers and students.

  9. Spatial distribution of trace elements in topsoils adjacent to main avenues of Sao Paulo city, Brazil

    International Nuclear Information System (INIS)

    In the present study, the concentration and distribution of Ba, Cu, Mo, Pb, S, Zn and Zr in soils collected along two main avenues (Pinheiros River Highway and Tiete River Highway) with high traffic density in the metropolitan region of Sao Paulo, Brazil, are presented, and their possible sources are discussed. These elements are strongly considered as contaminants originated from vehicular emissions. The analytical technique employed was XRF. The data set was evaluated by a t test for independent samples (group: avenues) at a 0.05 significance level. According to t test, the average contents obtained from Pinheiros River Highways are significantly different than the Tiete River, except for Mo. Multivariate statistic approaches (Pearson Correlation, Cluster and Factorial Analysis - FA) were adopted for data treatment. FA identified two main factors which accounted for about 86% of the total variance. The behavior of Ba, Cu, Pb, S and Zn were explained by the Factor 1. This indicates that the elements may have similar sources, probably related to gas emissions escaping from the vehicle fuel system. Factor 2 included Mo and Zr, suggesting their origin in the sample soils may be associated with the deterioration process of some device in the vehicular engine system or may be associated with the chemical composition of the urban soil analyzed.

    Measurements of external (outdoors) gamma exposure from natural background radiation have been used to estimate the average annual doses in Sao Paulo city. Twelve monitoring stations were placed in different regions of the town including both urban (where building materials are present) and outskirts areas. Seasonally surveys observing the four seasons from 2008 to 2010 have been carried out. The data were drawn from a 3-month sampling using the thermoluminescent dosimetry. The effective doses values are quite similar (slightly higher during the winter), so it can be considered that these results are not under significant influence (or variability) of seasonal environmental conditions like temperature, wind or rain. Dose values over the three years period, from Vila Carrao district, exclusively an urban location with mostly no green areas, present the highest values, while the lower values were always obtained for Tucuruvi district, near the biggest urban forest, Parque Estadual da Cantareira. Over the assessed period, the mean of the average annual effective doses was 1.3 {+-} 0.1 mSv.y{sup -1}. For the same period, the average annual background from nuclear and radioactive facility at IPEN was 0.75 {+-} 0.12 mSv.y{sup -1}. (author)

  11. Planetary Signatures in the SAO 206462 (HD 135344B) Disk: A Spiral Arm Passing Through Vortex?

    Bae, Jaehan; Hartmann, Lee

    2016-01-01

    The disk surrounding SAO 206462, a 8 Myr-old Herbig Ae star, has been recently reported to exhibit spiral arms, an asymmetric dust continuum, and a dust-depleted inner cavity. By carrying out two-dimensional, two-fluid hydrodynamic calculations we find that a planetary-mass companion located at the outer disk could be responsible for these observed structures. In this model, the planet excites primary and secondary arms interior to its orbit. It also carves a gap and generates a local pressure bump at the inner gap edge where a vortex forms through Rossby wave instability. The vortex traps radially drifting dust particles, forming a dust-depleted cavity in the inner disk. We propose that the vortex is responsible for the brightest southwestern peak seen in infrared scattered light and sub-mm dust continuum emission. In particular, it is possible that the scattered light is boosted as one of the spiral arms passes through the high density vortex region, although the vortex alone may be able to explain the peak...

  12. Rb-Sr geochronology from Sao Felix to Xingu: preliminary results

    International Nuclear Information System (INIS)

    Rb-Sr systematics have been applied on rocks from the Sao Felix do Xingu region, in the southeastern part of the State of Para. An age of 2716 ± 34 Ma with IR of 0.70292 ± 0.00030 (MSWD = 1.54) and an age of 2677 ± 50 Ma with IR of 0.70161 ± 0.00022 (MSWD = 5.21) had been obtained for a granitic body and a tonalitic body respectively, both of them associated to the green stones belts that occur in this area. Gneisses from the Xingu complex gave an age of 2574 ± 57 Ma with an IR of 0.70416 ± 0.00054 (MSWD = 5.06). An age of 1653 ± 14 Ma with IR of 0.70823 ± 0.02361 (MSWD = 1.71) had been obtained for the Velho Guilherme granite that crosscut the granite-green stones terrains. Such geochronological data show the existence of a magmatic event between 2.72 Ga and 2.68 Ga and permit us to conclude on the archaean age of the green stones terrains. (author)

  13. Petrography and geochronology of the Sao Jose dos Quatro Marcos granitoids, southwestern Mato Grosso, Brazil

    International Nuclear Information System (INIS)

    An area of about 400Km2 was mapped in the region of Sao Jose dos Quatro Marcos, southwestern State of Mato Grosso, western Brazil. Various granitoid rocks were recognized, intrusive into basement gneisses, and mapped as two distinct units, one of massive late granitoids (mostly 3a and 3b granites) and one of foliated granitoids, with oriented mafic minerals, consisting mainly of tonalites and, to a lesser degree, of granodiorites. The sequence of intrusion is from tonalites to granodiorites to late granites. Magmatic textures are usually preserved in the rocks, with the exception of some clearly recrystallized samples. Field aspects, as well as petrography and mineralogy, suggest a genetic relationship between the various granitoid types, showing overall features commonly cited as typical of 'I' lineages. A Rb/Sr whole-rock isochron obtained from 3b granites (six points) shows an age of 1,472 +- 19 Ma, and Sr8786 initial ratio of 0.7037 +- 0.0004; a nine point isochron (adding two tonalites and one granodiorite) yelds similar results (age of 1,505 +- 20 Ma, initial ratio of 0.7029+- 0.0003). The obtained ages confirm the existence of a thermal-magmatic event at about 1,500 Ma at the southern border of the Amazon Craton. (author)

  15. Assessment of metal concentrations in sediment samples from Billings reservoir, Rio Grande tributary, Sao Paulo, Brazil

    International Nuclear Information System (INIS)

    The present study chemically characterized sediment samples from the Billings reservoir, Rio Grande tributary, in the Metropolitan region of Sao Paulo, by determining metal concentration and other elements of interest. The chosen chemical parameters for this characterization were Aluminum, Arsenic, Barium, Cadmium, Copper, Chromium, Iron, Lead, Manganese, Mercury, Nickel, Selenium and Zinc. These parameters are also used in the water quality index, with the exception of Selenium. The concentrations were determined through different analytical techniques such as atomic absorption spectrometry (FAAS, GFAAS and CVAAS), optical emission spectrometry (ICP OES) and neutron activation analysis. These analytical methodologies were assessed for precision, accuracy and detection and/or quantification limits for the sediment elements in question. Advantages and disadvantages of each technique for each element and its concentration were also discussed. From these assessment the most adequate technique was selected for the routine analysis of sediment samples for each element concentration determination. This assessment verified also that digestion in a closed microwave system with nitric acid is efficient for the evaluation of extracted metals of environmental interest. The analytical techniques chosen were equally efficient for metals determination. In the case of Cd and Pb, the FAAS technique was selected due to better results than ICP OES, as it does not present matrix interference. The concentration values obtained for metals As, Cd, Cu, Cr, Hg, Ni, Pb and Zn in the sediment samples were compared to Canadian Council of Minister of the Environment (CCME) TEL and PEL values.

    The use of lichens as biomonitors of atmospheric pollutants has been considered as a very suitable tool when compared to conventional methods of direct measurements. Lichens in particular are widely used as biomonitors due to its easy sampling, low cost and resistance to environmental stresses. In this study, neutron activation analysis (NAA) was applied for element determinations in Canoparmelia texana lichenized fungi species. The samples were collected from tree barks in different sites at the Sao Paulo University Campus and in sites of areas considered non-polluted. Comparisons were made between the element concentration obtained in lichen from the study area and those from non-polluted sites. Results indicated that lichens from study area presented higher concentrations of As, Br, Ca, Cd, Co, Cr, Cs, Fe, K, La, Rb, Sb, Se and U than clean areas. The principal components analysis (PCA) was applied to the results obtained and five principal components were found as being responsible for almost 77 % of the variance. These findings suggest that element pollutants found may be associated with vehicular emissions, construction of buildings and metallurgical activities. (author)

    A study about household dust is being conducted to determine the level of metal contamination in the Sao Paulo Metropolitan Area (SPMA). The SPMA, with 18 million inhabitants, is one of the largest urban areas of the world, with serious environmental problems, due to the great amount of industries, heavy traffic and the disordered growth of population. The pollutants originate from a multiplicity of indoor and outdoor sources. Indoor sources are originated from residual (hair, skin scales), pets, human activities, construction materials, and furnishings as well as biological material (pollen, insect parts).and outdoor pollution, usually from the urban traffic. The pollutant mixture involved in numerous physical and chemical processes and changes its characteristics with time. Its composition and concentration depend on the strengths of indoor sources, the concentration of pollutants outside and the properties of ventilation and air-conditioning systems. It is well recognized that many metals have chronic effects on humans, in particular toddlers, who are at an higher risk compared to adults because they engage in greater hand to-mouth activity and their neurological systems are still developing. The household dust samples were collected from different localities, using vacuum cleaner, and sieved up to particle size <63 {mu}m, which were then analyzed for 7 elements by X-ray fluorescence technique. The fundamental parameters method (FP) was applied and the simple pressed powder technique for sample preparation was used. The concentrations preliminary results of metals in the household dust were Cr, 18-188 {mu}g g{sup -1}; Mn, 119-369 {mu}g g{sup -1}; Fe, 372-1464 {mu}g g{sup -1}; Ni, 33-85 {mu}g g{sup -1}; Cu, 42-303 {mu}g g{sup -1}; Zn, 156-1369 {mu}g g{sup -1} and Pb, 26-160 {mu}g g{sup -1}.

  20. Radioactivity in soils of the Sao Paulo State, Brazil

    International Nuclear Information System (INIS)

    Full text: For proper management of soil and groundwater quality, background levels of toxic elements in a given ecosystem must be known. The main aim of the present study is to perform a radioactive characterization of representative soils from the Sao Paulo State, in order to determine background levels for some selected radionuclides, which could be used as a quality reference value. Soil types and sampling places were chosen according to their representativeness and spatial distribution in the State geological formations, taking also into account their nearness to large urban areas. Thirty samples were collected in areas presenting low antrophic perturbation - native vegetation or ancient reforestation -, minimizing the chances that selected areas could have sustained antrophic effects in recent past. Activity concentration of U-nat, Th-nat, 228Th, 228Ra, 226Ra, 210Pb, 137Cs and 40K were evaluated and correlated with soil mineralogical characteristics. The samples were measured by means of passive gamma spectrometry and spectrophotometry, employing Arsenazo III. Results showed a wide variation on background levels for natural radionuclides of the uranium and thorium series, and very low concentration of 137Cs from radioactive fallout, ranging from -1 for U-nat, 8 to 82 Bq.kg-1 for Th-nat, 4.8 to 120 Bq.kg-1 for 228Th, 3.3 to 97.6 Bq.kg-1 for 228Ra, 1.0 to 61.8 Bq.kg-1 for 226Ra, -1 for 210Pb, 0.8 to 4.1 Bq.kg-1 for 137Cs and 15.3 to 516 Bq.kg-1 for 40 K. No significant correlation could be observed between the clay, silt and sand content in the samples and the respective activity concentration of the radionuclides. (author)

    Introduction Deproteinized bovine bone mineral (Bio-Oss) is a xenogenic bone substitute, widely used in maxillofacial bone regeneration. The aim of this in vitro study was to investigate its influence on the growth behavior of human osteosarcoma cell line, Saos-2 culture, and compare it with the physiologic dose of Dexamethasone, an inductive factor for osteoblasts. Materials and Methods Human osteosarcoma cells, Saos-2, were cultured on Bio-Oss and their growth rate was compared to Saos-2 cultures treated with Dexamethasone 10-7 M in contrast to cells cultivated in PBS, in the control group. Assessment of proliferation was performed after 24, 36, and 48 hours by counting cells using trypan blue exclusion method. Alkaline phosphatase was measured spectrophotometrically at 405 nm with paranitrophenol buffer. Results After 48 hours, the number of Saos-2 cells increased significantly when subcultured with Bio-Oss. Bio-Oss was more effective on the enhancement of proliferation of Saos-2 cells when compared to the physiologic dose of Dexamethasone (P<0.05). Alkaline phosphatase activity increased in cells grown on Bio-Oss and dexamethasone 10-7 M in contrast to cells cultivated in PBS control group. The greatest level of activity was observed in the group containing Bio-Oss after 48 hour. Conclusion The significant increase of cell proliferation and alkaline phosphatase activity in cells cultured on Bio-Oss, compared to Dexamethasone-treated cells, suggests the important role of this bone substitute in promoting bone regeneration.

    Full text: We have analyzed a large set of {alpha}-{alpha} elastic scattering data for bombarding energies ranging from 0.6 to 29.5 MeV. The complete lack of open reaction channels at these somehow low energies results in a vanishing imaginary part for the optical interaction. This characteristic makes the {alpha}-{alpha} reaction particularly interesting as the corresponding elastic scattering cross sections and phase shifts become very sensitive to the real part of the interaction. The data were analyzed within the context of the velocity-dependent Sao Paulo potential, which is a successful theoretical model for the description of heavy-ion reactions from sub-barrier to intermediate energies. We have shown that, even in this low energy region, the velocity dependence of the Sao Paulo potential model is a necessary ingredient for describing the data. Despite the reasonable description obtained with the Sao Paulo potential, the analyses indicate the necessity of an additional weak dependence of the interaction on the angular momentum. These important characteristics open the possibility for studying reactions with astrophysical interested. In particular, predictions of the astrophysical S-factor for the {sup 12}C({alpha},{gamma}) reaction will be presented. The understanding of the reaction rate for the {alpha}-capture process by a {sup 12}C nucleus is a crucial ingredient for predicting the stellar helium burning and the subsequent fate of stars as this reaction determines the ratio of carbon to oxygen towards the end of the Red Giants phase. It is well known that low mass stars evolve to White Dwarfs and this ratio determines the final abundance composition in White Dwarf matter and sets the trigger conditions for type Ia supernova explosions. The carbon-oxygen ratio also dictates the subsequent sequence of burning processes during the final stages of stellar evolution for massive stars. Thus, it has a key role in the determination of the abundance composition in

    The Guarani aquifer system (GAS) is an important public water source. The unconfined areas are those where the aquifer is more vulnerable to contamination, justifying the creation of a Protection and Recovery Source Area (Area de Protecao e Recuperacao de Manancial - APRM), as established in Act 9.866/97 of Sao Paulo State. We present here the results of the project Environmental Diagnosis in Support of the Plan for the Development and Environmental Protection Plan of the Outcrop Area of the Guarani Aquifer System in Sao Paulo State (Plano de Desenvolvimento e Protecao Ambiental da Area de Afloramento do Sistema Aquifero Guarani no Estado de Sao Paulo PDPA-SAG) and describe the areas of intervention defined by this law. The characterization of the area studied focuses on the physical and socio-economic aspects of the region, in addition to the pertinent legislation. Partial results indicate that the condition of the aquifer is satisfactory, but territorial discipline continues to be of prime importance. (Author)

    This work shows the results of a monitoring carried out in an area of about 21 km{sup 2}, Dobrada Municipality, central west region of the state of Sao Paulo (Brazil), where the impacts in ground water and surface water were evaluated by the infiltration and percolation of vinasse and water used for washing cane sugar, through accumulation ponds and decantation reservoirs, respectively, in areas of Bauru Aquifer (Cretaceous). The Bauru Aquifer, free and porous, occurs in a extended area of 104.000 km{sup 2} in Sao Paulo State, as a major exploitable aquifer (more than 15.000 wells), used for domestic and industrial water supplies. For the groundwater, the following measures were found in analyses exceeding drinking water standards (WHO; CONAMA/Brazil and Sao Paulo State): manganese (0,03 to 3,5 mg/l), iron (0.45 to 34 mg/l), aluminum (1 to 52 mg/l) and phosphate (0,03 to 0.38 mg/l). For superficial water, the following measures exceeded drinking water standards: total iron (3 mg/l) and phosphate (0,035 mg/l). The main purpose of this research is to improve the field methodology to characterize the impacts of vinasse and washing water of cane sugar infiltration/percolation., detaching the relationship between ground and surface water, with the major aim to supply the legislation to protect drinking water resources.

    A preliminary investigation concerning to the geochemical behaviour of uranium isotopes (233 U and 238 U) was performed on spring waters for Aguas de Lindoia city, Sao Paulo State. The reason for this study is because the natural radioactivity of these waters is poorly known, and no uranium content data have been published. Measurements of Uranium-238 contents and 234 U/238 U activity ratios in groundwaters were performed on the following springs issuing in the urban area from Aguas de Lindoia: Levissima I, Levissima II, Beleza, Sao Roque, Lindalia and Santa Izabel.

  12. Determination of natural radioactivity in public water supplies of Sao Paulo State. V.1-2

    International Nuclear Information System (INIS)

    This study aimed to determine the activity concentrations of natural occurring radionuclides of the 238U and 232Th series in drinking water supplies of Sao Paulo State. A sampling program was carried out, in order to perform this survey, starting in 1994 and covering 54% of the 574 existing counties. The locations studied correspond to the public water systems operated routinely by SABESP - Companhia de Saneamento Basico do Estado de Sao Paulo, which is the state company responsible for collecting, treating and supplying water. The activity concentrations of 226Ra and 228Ra were determined by gross alpha and beta counting, respectively, of a Ba(Ra)SO4 precipitate in a low-background gasflow proportional counter. The 228Rn concentrations were determined by liquid scintillation method. Concentrations up to 235 mBq/L and 131 mBq/L were observed for 226Rn and 228Ra, respectively, whereas 222Rn concentrations reached 315 Bq/L. Of the 452 water samples analyzed, a total of 3 presented activity concentrations for 226Ra above the limit of 0.1 Bq/L adopted by the Brazilian regulation for the gross-alpha activity in drinking water. These results, however, are below 1/50 of the annual limit of intake recommended for 226Ra by 'Comissao Nacional de Energia Nuclear', if an ingestion rate of 2L/d per person is considered. For the gross-beta activity, all the measured samples presented 228Ra activity concentrations below 1 Bq/L. It is concluded that the consumption of such waters will not imply in any additional health risk to the population. In order to evaluate the radioactive doses due to the ingestion of these waters, a conservative dosimetric calculation was carried out using dose conversion factors suggested by ICRP (International Commission on Radiological Protection). Doses up to 0.3 mSv/y, 0.6 mSv/y and 3.2 mSv/y were estimated for the critical organs, for the ingestion of 226Ra, 228Ra and 222Rn, respectively; while the corresponding committed effective doses reached

  13. Fluvial fluxes of natural radium isotopes and dissolved barium for Ubatuba embayments, Sao Paulo

    International Nuclear Information System (INIS)

    Radium isotopes are among the most important isotopes in the environment from both radioprotection and geo-hydrological points of view. They are also a powerful tool for studying geohydrological processes and have been used intensively as tracers of groundwater sources that discharge into the coastal ocean.The complex exchange of fluvial, subsurface and seawater within a coastal area directly affects global biogeochemical cycles. Environmental scientists have few tools to accurately quantify such processes and must therefore rely on various tracer techniques. Radium isotopes have been frequently applied as tracers of submarine groundwater discharge (SGD). The unique radium signature of SGD is acquired within the subterranean estuary, a mixing zone between fresh groundwater and seawater in coastal aquifers. In this study we determined the fluvial fluxes of the radium isotopes and dissolved barium for Ubatuba embayments, northernmost part of Sao Paulo Bight. The research work was carried out from April/ 2007 to August/ 2007 and covered 17 small rivers sources that belong to the major surface draining system of such coastal area. During this period of investigation, groundwater samples were also collected from 10 sources available in this coastal region. Activity concentrations of 223Ra in riverine waters discharging to Ubatuba and Caraguatatuba embayments varied from -1 to 335 mBq 1000L-1 (in Cocanha River), while 224Ra concentrations ranged from 17 mBq 100L-1 to 7270 mBq 100L-1. Activity concentrations up to 1424 mBq 100L-1 were observed for 226Ra in riverine waters, while 228Ra concentrations varied from 1412 mBq 100L-1 to 4058 mBq 100L-1. Groundwater activity concentrations of 223Ra varied from 1 mBq 100L-1 to 126 mBq 100L-1, while 224Ra ranged from 118 mBq 100L-1 to 3701 mBq 100L-1. 223Ra/ 224Ra activity ratios up to 0.7x10-1 and 0.2 were observed in riverine and groundwater, respectively. For 226Ra groundwater activity concentrations ranged from 100 mBq 100L-1

  14. Natural radionuclides and 137Cs in commercialized edible mushrooms in Sao Paulo-Brazil

    International Nuclear Information System (INIS)

    Artificial and natural radionuclides are commonly found in several compartments of the earth's crust. Some mushroom species have a high capacity to absorb radionuclides and toxic elements from the soil. Diet is considered as one of the main routes of radioactive contamination. Therefore, radioactivity measurements in the environment and in food are extremely important to monitor the radiation levels that human can be exposed to either directly or indirectly. Environmental bio monitoring has demonstrated that diverse organisms such as crustaceans, fish and mushrooms are useful when evaluating both the contamination and the quality of the ecosystems. There are actually several radionuclides that can be accumulated in mushrooms, including 40K, 137Cs, 232Th and 238U. There are few studies in the Southern hemisphere countries, on the natural and artificial radioactivity levels in mushrooms. The present study evaluated 40K, 137Cs, 232Th and 238U in commercialized edible mushrooms in the state of Sao Paulo, Brazil. The edible mushroom samples were acquired in different commercial establishments in the Sao Paulo metropolitan region, specifically in Municipal Markets. Some samples were acquired directly from producers located in the cities of Mogi das Cruzes, Mirandopolis, Suzano and Juquitiba. About 400g were collected for each edible mushroom species, which included Agaricus sp, Pleurotus sp and Lentinula sp species. All the samples were prepared and stored in polyethylene bottles for approximately 35 days, so that secular equilibrium could be established before counting. The 40K, 137Cs, 232Th and 238U gamma activities were measured by gamma spectrometry. The equipment consisted of a Hyper pure Germanium detector connected to an electronic system. The detector efficiency was obtained from measurements of reference materials: IAEA-300, IAEA-327 and IAEA-375. The results for the specific activities in edible mushrooms samples ranged fi-om 461 to 1535 Bq kg-1, 1.4 to 10.6 Bq

    An 8-10 station Lightning Mapping Array (LMA) network is being deployed in the vicinity of Sao Paulo to create the SP-LMA for total lightning measurements in association with the international CHUVA [Cloud processes of the main precipitation systems in Brazil: A contribution to cloud resolving modeling and to the GPM (Global Precipitation Measurement)] field campaign. Besides supporting CHUVA science/mission objectives and the Sao Luiz do Paraitinga intensive operation period (IOP) in November-December 2011, the SP-LMA will support the generation of unique proxy data for the Geostationary Lightning Mapper (GLM) and Advanced Baseline Imager (ABI), both sensors on the NOAA Geostationary Operational Environmental Satellite-R (GOES-R), presently under development and scheduled for a 2015 launch. The proxy data will be used to develop and validate operational algorithms so that they will be ready for use on "day1" following the launch of GOES-R. A preliminary survey of potential sites in the vicinity of Sao Paulo was conducted in December 2009 and January 2010, followed up by a detailed survey in July 2010, with initial network deployment scheduled for October 2010. However, due to a delay in the Sao Luiz do Paraitinga IOP, the SP-LMA will now be installed in July 2011 and operated for one year. Spacing between stations is on the order of 15-30 km, with the network "diameter" being on the order of 30-40 km, which provides good 3-D lightning mapping 150 km from the network center. Optionally, 1-3 additional stations may be deployed in the vicinity of Sao Jos dos Campos.

    In the present study instrumental neutron activation analysis has been applied to determine the elements accumulated in samples of Canoparmelia texana, a specie of lichen, collected in regions with different levels of pollution: Intervales State Park, an area considered non polluted that belongs to Atlantic Forest ecosystem and distinct sites in the metropolitan region of Sao Paulo city. The results obtained in the analysis showed that samples collected in the clean area indicated lower concentrations of elements than those obtained for samples from metropolitan region. The concentrations of the elements Ba, Ca, Cl, Fe, K, Mn, Na, Rb and Zn were obtained at {mu}g g{sup -1} levels and the elements As, Br, Co, Cr, Cs, La, Sb, Sc, Se and U at ng g{sup -1} levels. Cluster analysis was applied to classify into distinct groups the sites using the element concentrations in these samples. The accuracy and precision of the results were evaluated by IAEA 336 Lichen reference material analysis and the data given for this material were in agreement with certified values with relative standard deviations lower than 11,4%.

    The Guarapiranga Reservoir, located in Sao Paulo metropolitan region, Brazil, is responsible for supplying about 20% of the entire population's water needs of this region or approximately 3.7 million people. However, this system has shown significant degradation in water quality, due to untreated domestic sewage and industrial effluents. In this study sediment samples were collected at five points along the reservoir and total concentration of some major (Fe, K and Na), trace (As, Ba, Br, Co, Cr, Cs, Hf, Hg, Rb, Sb, Sc, Ta, Tb, Th, U, V and Zn) and rare earth (Ce, Eu, La, Lu, Nd, Sm, Tb and Yb) elements were determined by instrumental neutron activation analysis (INAA). By inductively coupled plasma optical emission spectrometry (ICP OES) the concentrations of Al, Ba, Be, Ca, Co, Cr, Cu, Fe, K, Li, Mg, Mn, Na, Ni, Pb, Ti, V e Zn were determined after digestion procedure following US EPA 3051 methodology. The concentrations of metals Cd and Pb were determined by graphite furnace atomic absorption spectrometry (GFAAS) and total Hg by cold vapor atomic absorption spectrometry (CVAAS). Methodology validation according to precision and accuracy was performed by reference materials analyses for the three different analytical techniques used. Multielemental results obtained by INAA were compared to NASC (North American Shale Composite), Upper Continental Crust (UCC) and soil from Guarapiranga park values. The Enrichment Factor (EF) and Geo accumulation Index (Igeo) were also evaluated for these data. Metal concentration results by ICP OES and AAS in the samples were compared to the TEL and PEL oriented values established by the Canadian Council of Ministers of the Environment and also adopted by CETESB (Environmental Protection Agency of the Sao Paulo State). The results were also compared to regional reference values (VRR) of limnic sediments from the Alto Tiete Basin.

    Medical irradiation contributes with a significant amount to the dose received by the population. Here, this contribution was evaluated in a survey of absorbed doses received by patients submitted to chest radiological examinations (postero-anterior (PA) and lateral (LAT) projections) in hospitals of the city of Sao Paulo. Due to the variety of equipment and procedures used in radiological examinations, a selection of hospitals was made (12, totalizing 27 X-ray facilities), taking into account their representativeness as medical institutions in the city, in terms of characteristics and number of radiographs carried out. An anthropomorphic phantom, provided with thermoluminescent dosemeters (TLD-1 00), was irradiated simulating the patient, and the radiographic image quality was evaluated. Absorbed doses were determined to the thoracic region (entrance and exit skin and lung doses), and to some important organs from the radiation protection point of view (lens of the eye, thyroid and gonads). The great variation on the exposure parameters (kV, mA.s, beam size) leads to a large interval of entrance skin doses-ESD (coefficients of variation, CV, of 60% and 76%, for PA and LAT projections, respectively, were found) and of organ doses (CV of 60% and 46%. for thyroid and lung respectively). Mean values of ESD for LAT and PA projections were 0.22 and 0.98 mGy, respectively. The average absorbed doses per exam (PA and LAT) to thyroid and lung, 0.15 and 0.24 mGy respectively,showed that the thyroid was irradiated by the primary beam in many cases. Values of lens of the eye and gonad absorbed doses were below 30 {mu}Gy. Comparison of the lung doses obtained in this study with values in the literature, calculated by Monte Carlo simulation, showed good agreement. On the other hand, the comparison shows significant differences in the dose values to organs outside the chest region (thyroid, lens of eye and gonads).

    It is well-known that, fish is an important source of protein for populations around the world. As such, fish consumption has increased because it is a healthy and low cholesterol source of protein and other nutrients. The city of Iguape, in the extreme south of the Sao Paulo State coast, is located in a well-preserved Atlantic Forest region. During the last two centuries the city suffered from drastic environmental changes, reinforcing the importance of environmental monitoring in this region. In the present study, 23 samples of the three most consumed fish species by the Iguape city population were analyzed. Fish samples were bought at local markets, conditioned in isothermic boxes in crushed ice (-4 deg C) and then identified before registering the biometric information (total length, total weight and body weight). The following micro and macronutrients As, Br, Ca, Co, Fe, K, Na, Rb, Sc, Se and Zn concentration in muscle from 02 predatory fish species Macrodon ancylodon (King weakfish - Pescada) and Centropomus parallelus (Fat snook - Robalo peba) and one detritivorus species: Anchoviella lepidentostole (Broadband anchovy - Manjuba) were assessed by INAA. Toxic metals Cd, Hg and Pb were also evaluated by AAS. Statistical correlation between element concentrations and fish species were tested. (author)

  5. The geotectonic evolution of southern part of Sao Francisco Craton, based in geochronologic interpretation

    International Nuclear Information System (INIS)

    Interpretation of available radiometric data from poly metamorphic terranes of southern part of the Sao Francisco Craton demonstrates the importance of geochronology as a tool in the study of ancient crustal evolution. In addition, radiometric study of basic intrusive magmatism helps define the most important epochs of crustal rifting during the Proterozoic. The definition of the southern border of the cratonic area based on distinctive age patterns of the geochronological provinces is also discussed. Finally, the geochronologic evolution of the Bambui platform cover is presented. Approximately 250 radiometric age determinations (Rb-Sr, K-Ar and Pb-Pb methods) were interpreted principally through the use of iso chronic diagrams. The geologic history tectonomagnetic events identified in this study is compared to the crustal evolution of similar segments of the Sao Francisco Craton and elsewhere. (author)

    Archaeometry is a consolidated field with a wide application of nuclear analytical techniques for the characterization, protection, and restoration of archaeological pieces. This project aimed at studying the elementary chemical composition of 70 ceramic fragments samples from Sao Paulo II archaeological site, located along the Solimoes River channel, next to Coari city, in Brazilian Amazon. The characterization of samples was performed by neutron activation analysis (NAA). By the determination of 24 elements in the ceramic fragments ( Ce, Co, Cr, Cs, Eu, Fe, Hf, K, La, Lu, Na, Nd, Sb, Sm. Rb, Se, Ta, Tb, Th, U, Yb and Zn), it was possible to define groups of samples regarding the similarity/dissimilarity in elementary chemical composition. For such a task, the multivariate statistical methods employed were cluster analysis (C A), principal component analysis (PCA) and discriminant analysis (DA). Afterwards, seven ceramic fragments were selected based on the groups previously established, for the characterization of the site temporal horizon. Those ceramic fragments were analyzed by thermoluminescence (TL) and EPR for dating purposes. The firing temperatures were determined by electron paramagnetic resonance (EPR) technique, in order to infer about some aspects of the ceramic manufacture employed by the ancient peoples that lived in Sao Paulo 11. By the results obtained in this study, it was possible to identify the quantity of clay sources employed by the ceramists and the age of the ceramic pieces. Therefore, the results of this research may contribute to the study on the occupation dynamics in the pre-colonial Brazilian Amazon. (author)

    One of the fundamental problems to understanding the evolution of volcano-sedimentary sequences in southeastern Brazil is constraining their depositional ages. Brasiliano tectonic and metamorphic either obscured or destroyed primary features, such as unconformities, as well as other geologic relationships. This problem is exemplified by the Serra do Itaberaba and Sao Roque groups, where the lack of data about the timing of their deposition has prevented resolution of proposed one-and two-stage geotectonic/depositional models. Recent U-Pb zircon data obtained from metavolcanic rocks in the Sao Roque Group indicate that it was deposited between 628 and 607 Ma. New U-Pb zircon data of 1395{+-} 10 Ma for a metandesite in the basal Morro da Pedra Preta Formation (Serra do Itaberaba Group) indicate the maximum age for the beginning of the deposition of the pelites overlying MORB-like basalt. A metarhyolite of the upper unit, the Nhangucu Formation, contains two zircon populations. One yielded an age of 619 {+-}3 Ma, which defines the crystallization age of the rock, and the other an age of 1449 {+-}3 Ma, interpreted as inherited xenocrystal grains from older units of the Serra do Itaberaba Group. The younger metarhyolite was affected only by the S{sub 2} foliation, generated during the Brasiliano orogenesis, whereas the Middle Proterozoic metavolcano-sedimentary sequence records additional metamorphic and deformational events, confirming the presence of two different geotectonic cycles.

Este capítulo aborda a variabilidade genética e fenotípica da doença, demonstrando sua relevância no entendimento da fisiopatologia e na avaliação clínica de SAOS.The physiopathology of obstructive sleep apnea syndrome (OSAS results from the interaction between genetic and environmental factors. The principal risk factors are obesity and age. Other relevant risk factors are craniofacial abnormalities, hypothyroidism and menopause, as well as the use of alcohol and sedatives. By virtue of its association with factors such as HLA levels, obesity, genetic syndromes, ethnicity, excessive sleepiness, alterations in ventilatory control and expression of inflammatory mediators, OSAS has been related to heritability. This chapter addresses the genetic and phenotypic variability of the disease, showing its relevance in the understanding of the physiopathology and clinical evaluation of OSAS.

    The watershed region of the Ribeira do Iguape River and the estuarine complex of the Paranagua-Iguape- Cananeia and the various river basins located between this region and the Atlantic Ocean, is known as the Ribeira Valley. The Ribeira do Iguape River runs a total length of approximately 470 km, being the main source of fresh water in the Estuarine Complex of the Iguape-Cananeia-Paranagua (Lagamar). The Ribeira do Iguape River is the last major river in the State of Sao Paulo that has not been altered by dams. During virtually the entire 20th century, the region of the Ribeira Valley was the scene of constant environmental degradation resulting from the intense exploration and refining of lead, zinc and silver ores that were processed in the mines of the region, in a rudimentary way and without any control over environmental impacts. Since 1996, all such activities ceased, however, leaving behind a huge amount of environmental liabilities. This study aims to investigate the presence and concentration levels of metals and semi-metals arsenic (As), cadmium (Cd) and lead (Pb) in the sediment and water of aquatic systems of Ribeira do Iguape River and its tributaries, for an environmental assessment and monitoring of the region. The determination of these elements was carried out by GF AAS technique for water samples and ICP OES for the sediment samples. This study also assessed the occurrence of some major (Ca, Fe, K and Na), trace (As, Ba, Br, Co, Cs, Hf, Rb, Sb, Sc, Se, Ta, Th, U, Zn) and rare earth elements (La, Ce, Eu, Nd, Sm, Lu, Tb and Yb) by Neutron Activation Analysis (NAA). Validation of both methodologies, according to precision and accuracy, was done by reference material analyses. The results obtained for As, Cd and Pb were compared to the Canadian Environmental oriented values (TEL and PEL). The results obtained for multielemental analyses in the sediment samples were compared to UCC values (Upper Continental Crust). (author)

    This study assessed the feasibility of Concentrated Solar Power plants (CSP) in Northeast, Brazil. It focused on parabolic trough solar power plants, which is the most mature CSP technology; and evaluated plants rated at 100 MWe, dry cooling systems (due to the low water availability in Northeast), and with and without hybridization based on natural gas (degree of hybridization varying from 25 to 75%). Hence, the capacity factor of the simulated plants hovered between 23 and 98%, according to the degree of hybridization and the choice of the thermodynamic cycle of the natural gas fueled thermal system: Rankine or combined cycle. The CSP plants were simulated at Bom Jesus da Lapa, in the semi-arid region of Bahia. Given the prospects for natural gas resources in the Sao Francisco Basin, different scenarios for the gas prices were tested. Moreover, two scenarios were tested for the cost of the CSP plants, one based on the current financial environment and the other based on incentive policies, such as fiscal incentives and loans. Findings show that while simple plants levelized costs (LCOE) hovered around 520 R$/MWh, for hybrid plants LCOE may reach 140 to 190 R$/MWh. Therefore, this study proposed incentive policies to promote the increasing investment in hybrid CSP plants. (author)

    The present study chemically characterized sediment samples from the Billings reservoir, Rio Grande tributary, in the Metropolitan region of Sao Paulo, by determining metal concentration and other elements of interest. The chosen chemical parameters for this characterization were Aluminum, Arsenic, Barium, Cadmium, Copper, Chromium, Iron, Lead, Manganese, Mercury, Nickel, Selenium and Zinco. These parameters are also used in the water quality index, with the exception of Selenium. The concentrations were determined through different analytical techniques such as atomic absorption spectrometry (FAAS, GFAAS and CVAAS), optical emission spectrometry (ICP OES) and neutron activation analysis. These analytical methodologies were assessed for precision, accuracy and detection and/or quantification limits for the sediment elements in question. Advantages and disadvantages of each technique for each element and its concentration were also discussed. From these assessments the most adequate technique was selected for the routine analysis of sediment samples for each element concentration determination. This assessment verified also that digestion in a closed microwave system with nitric acid is efficient for the evaluation of extracted metals of environmental interest. The analytical techniques chosen were equally efficient for metals determination. In the case of Cd and Pb, the FAAS technique was selected due to better results than ICP OES, as it does not present matrix interference. The concentration values obtained for metals As, Cd, Cu, Cr, Hg, Ni, Pb and Zn in the sediment samples were compared to Canadian Council of Minister of the Environment (CCME) TEL and PEL values.

    Submarine groundwater discharge (SGD) and recycled seawater can provide chemical constituents to coastal zone, representing an important material flux pathway from land to sea in some areas. Geochemical tracers, like {sup 222} Rn and {sup 226} Ra, are advantageous for regional-scale assessment of SGD, because their signals represent values integrated through the water column that removes small-scale variations. These radionuclides are usually enriched in groundwater compared to seawater, can be measured at very low concentrations and are conservative. This work reports preliminary results of a study carried out in a series of small embayements of Ubatuba, Sao Paulo State-Brazil, covering latitudes between 23 deg 26{sup '}S and 23 deg 46{sup '}S and longitudes between 45 deg02{sup '}W and 45 deg 11{sup '}W. The main aims of this research were to set up an analytical method to assess {sup 222} Rn and {sup 226} Ra activities in seawater samples and to apply the excess {sup 222} Rn inventories obtained to estimate the submarine groundwater discharge. Measurements made during 2001/2002 included {sup 222} Rn and {sup 226} Ra in seawater, {sup 222} Rn in sediment, seawater and sediment physical properties. (author)

    Atmospheric pollution in the Sao Paulo Metropolitan Area (SPMA) has been investigated using the WRF/Chem model version 3.2.1 in a 1X1 km emission grid. Based on a local emission inventory, a control simulation (CTRL) was performed for the period 28/01-02/02/2014, during a summer season characterized by intense solar radiation and temperature positive anomalies, which resulted in high pollutant concentration. Sensitivity tests were performed using different vehicular emission scenarios and CTRL. In scenario A), emissions were removed from a region which encompasses almost the entire urban area of the SPMA, only roads in the outskirts had regular emissions. Comparing scenario A) to CTRL, sharp decreases in CO, NO and NO2 were observed inside the SPMA. Ozone decreased slighlty during the day, probably due to the significant absence of precursor emissions which form ozone during the day in the presence of sunlight. On the other hand, ozone concentrations increased at night, influenced by the absence of ozone-consuming precursors inside the densely urbanized SPMA, in the absence of sunlight. In scenario B), we removed emissions from a smaller area, corresponding roughly to an expanded downtown area (where a few traffic restriction laws operate). The goal of this scenario was to observe possible impacts if more strict traffic restriction laws were implemented. In scenario C), emissions were decreased by 50% in the same area, in an attempt to characterize concentrations in an urban toll scenario. Results from scenarios B) and C) showed a decrease in NO, NO2 and CO, but less intense than in scenario A). On the other hand, a higher increase in ozone was detected both during the day and at night compared to the CTRL and scenario A). These results suggests that, along with lower concentrations of precursor gases and CO, higher ozone concentrations are likely to be expected in downtown Sao Paulo if more severe traffic restriction laws should be implemented. This is concerning

  17. Energy rating and productive of wood from reforestation of Eucalyptus and Pinus genetically improved in the state of Sao Paulo

    International Nuclear Information System (INIS)

    Full text: In recent years, wood consumption is increasing, and the need to increase the availability of commercial wood reforestation becomes essentially important. In the state of Sao Paulo a few species of Eucalyptus and Pinus have stood out for having high productivity and with updated technical genetic improvements to productivity can be increased to 60 %. The work has to evaluate the productivity and quality of wood provided with commercial reforestation species of Eucalyptus and Pinus genetically improved in the midwestern region of Sao Paulo. In this study we used six treatments: a seminal Eucalyptus grandis; two clones of Eucalyptus grandis, three hybrid clones of Eucalyptus urophylla x Eucalyptus grandis. Pinus were analyzed for five hybrid progenies of Pinus caribaea var. hondurensis and Pinus tecunumanii. We evaluated the productivity rates of each treatment and the quality of wood produced, by studying their average density and specific variations possible by the methods: TARG (Technique attenuation of gamma radiation from 241Am) and immersion. Productivity mass IMAM treatments for Eucalyptus S1, C1, C2, H1, H2 and H3 were 18.7, 17.0, 21.2, 28.1, 30.1 and 27.2 ton/ha.years respectively, and the density point to 12 % treatments S1, C1, C2, H1, H2 and H3 were 451.3, 439.0, 411.9, 518.8, 526.4 and 526.3 kg/m3. Productivity for Pinus mass IMAM treatments H1, H2, H3, H4, H5 and S1 were 14.7, 13.5, 13.7, 14.8, 12.4 and 13.0 ton/ha.years respectively, and the density point to 12 % treatments H1, H2, H3, H4, H5 and S1 were 475, 522, 459, 478, 430 and 514 kg/m3. These results are extremely important and come to contradict some literature results that correlate productivity gains with losses in density. It was concluded that the values of density and productivity of each treatment and sperm Pinus hybrids there was significant improvement in the indices assessed. While in the Eucalyptus the results were remarkable, reflecting the improvement in productivity for

    Full Text Available The Atlantic Forest small mammal land fauna, except bats, and the abiotic factors that might have an influence on its composition, were studied in the Itapevi County, State of Sao Paulo, a forested region, partly altered by antropic action, from January, 1995 to June, 1996. The trapping effort consisted of 2,888 trap-nights, resulting in a 4.6% trapping success and consisted of monthly trappings, for five consecutive days. During this period, 134 specimens were captured, of which 46.3% were Didelphimorphia and 53.7% were Rodentia. Eleven species were registered: two Didelphimorphia: Didelphis marsupialis (Linnaeus, 1758 and Marmosops incanus (Lund, 1841, and nine Rodentia: Akodon cursor (Winge, 1887, Bolomys lasiurus (Lund, 1841, Oxymycterus hispidus Pictet, 1843, Oxymycterus nasutus (Waterhouse, 1837, Oligoryzomys nigripes (Olfers, 1818, Oryzomys angouya (Fischer, 1814, Raltus norvegicus (Berkenhout, 1769, Euryzygomatomys spinosus (G. Fischer, 1814 and Cavia aperea Erxleben, 1777. The relative density indices were correlated with meteorological data by Spearman and Pearson coefficients. For marsupials these correlations were not significant. For rodents, the correlations were significant and directly related to lower temperature and rainfall indices (p<0.05. During the dry season the occurrence of small mammals was 50% greater than during the wet season, probably due to foraging strategies in the studied fragment of Atlantic Forest.

    Full Text Available Asteraceae, with around 2,000 species registered in Brazil, stand out in the ethnobotanical studies, placing them almost always among the four families with the greatest number of species in the useful flora, especially for medicinal purposes. In this study, one investigated the importance of this family in four rural communities in the town of Camocim de Sao Felix, in an altitude swamp, in the agreste region of the State of Pernambuco, Brazil. The field works were conducted within the period from December 2010 to May 2011. For the collection of ethnobotanical data, semi-structured interviews were conducted with 50 inhabitants, of both sexes, most of them farmers, with family income less than one minimum wage, and there was collection of species cited by them. The respondents showed a varied knowledge on the Asteraceae, citing 19 species, in the following categories: medicinal (12, ornamental (6, technological (3, and alimentary (2, some of them included in more than one category. Acanthospermum hispidum DC., ruderal species know as bristly starbur, was the most frequently cited as medicinal plant, indicated for the treatment of respiratory problems, infections, kidney diseases, and toothaches. The species Dahlia pinnata Cav., Tagetes erecta L., and Zinnia elegans Jacq. are used as ornamental plants. Lactuce sativa L. (cultivated and Emilia sonchifolia (L. DC. (weed were the only ones cited as alimentary and Conyza bonariensis (L. Cronquist, Egletes viscosa Less., and Parthenium hysterophorus L. were cited for technological purposes.

  20. Airline Choice for Domestic Flights in Sao Paulo Metropolitan Area: An Application of the Conditional Logit Model

    Moreno, Marcelo Baena

    2006-01-01

    Using the conditional (multinomial) LOGIT model, this paper addresses airline choice in the S o Paulo Metropolitan Area. There are two airports in this region, where two, three or even four airlines compete for passengers flying to an array of domestic destinations. The airline choice is believed to be a result of the tradeoff passengers face among flight cost, flight frequency and airline performance. It was found that the lowest fare better explains airline choice than the highest fare, whereas direct flight frequencies give better explanation to airline choice than indirect (connections and stops) and total (direct plus indirect) ones. Out of 15 variables tested, the lowest fare was the variable that best explained airline choice. However, its signal was counterintuitive (positive) possibly because the cheapest airline was offering few flights, so passengers overwhelmingly failed to choose the cheapest airline. The model specification most adjusted to the data considered the lowest fare, direct flight frequency in the travel day and period (morning or afternoon peak) and airline age. Passengers departing from S o Paulo-Guarulhos International Airport (GRU) airport make their airline choice in terms of cost whereas those from Sao Paulo-Congonhas Airport (CGH) airport do not. Finally, senior passengers place more importance on airline age than junior passengers.

  1. Determination of REE and U in agricultural soils from Jaguari River basin, Sao Paulo, by neutron activation analysis

    International Nuclear Information System (INIS)

    Uranium has the highest atomic weight of the naturally occurring elements. It is weakly radioactive and occurs naturally in low concentrations (a few parts per million) in soil, rock and water. The rare earth elements (REE) form the largest chemically coherent group in the periodic table. The versatility and specificity of the REE have given them a level of technological, environmental, and economic importance considerably greater than might be expected. The objective of this work was to determine the concentration of the lanthanides (La, Ce, Nd, Sm, Eu, Tb, Yb and Lu), and U, considering the soil use and occupation from the Jaguari river basin, Sao Paulo. Instrumental Neutron Activation Analysis (INAA) was used for the REE and U analysis The study area is located in a traditional agricultural area which is nowadays one of the main industrial regions of Brazil. In order to evaluate the quality of these soils in relation to lanthanides and U levels, the obtained concentrations were compared to guiding values reported by environmental protection agencies. The 75th percentile for U in agricultural soils (2.76 mg kg-1) was higher than in the control areas (1.61 mg kg-1), but much lower than the maximum allowed concentration for soils in The Netherlands (28.3 mg kg-1). The lanthanides presented concentration levels higher than the guiding values of the RIVM - -National Institute for Public Health and the Environment guidelines. (author)

    The paper describes and discusses results of the determination, by alpha spectrometry, of the natural thorium isotopes in groundwaters associated with different rock types in Aguas da Prata spa, state of Sao Paulo. The dissolved Thorium is relatively low (0.003 to 1.72 mg.L{sup -1} for {sup 232}Th), while the {sup 22}'8Th/{sup 232}Th isotopic ratios for dissolved thorium were higher than unity (1.8 to 34). The thorium concentration in suspended solids of these waters ranged between 183 up and 3445 mug.g{sup -1} and indicates that significant thorium transport occurs under this condition. The obtained results allowed to calculate the factor for preferential mobilization of thorium in particulate matter relative to the liquid phase, an important parameter for understanding the geochemical behaviour of this element in hydrosphere.

  4. Environmental quality of agricultural soils within the Jaguari River Basin - Sao Paulo

    International Nuclear Information System (INIS)

    Environmental impacts have occurred in various forms and intensities on soil, water and air media. Consequently, several countries have used legal criteria for soil protection, either by means of generic guiding values or through case-by-case risk assessment. The Sao Paulo Environmental Agency (CETESB) pioneered the publication of guiding values for soils and groundwater in 2001. The aim of this study was to evaluate the environmental quality of agricultural soils in comparison to pristine soils (control areas) within the Jaguari river basin, Sao Paulo. The evaluation was carried out through multielement determination by Neutron Activation Analysis Instrumental (INAA) technique. The analyses were also complemented by Optical Emission Spectrometry Coupled Plasma (ICP OES), Atomic Absorption Spectrometry and Graphite Furnace (GFAAS) techniques. The results obtained in the analyzed soil samples were compared to the guiding values established by the Sao Paulo State environmental legislation and revealed that there were no median concentrations above the prevention values. The median concentrations for the elements Sb, As, Cd, Pb, Co, Cu, Cr, Ni, V and Zn were below the reference values, except for Pb. Taking into account the 34 elements determined, there were statistically significant differences (p <0.05) between agricultural and pristine soils only for the elements Ba, As, U and V. Among these elements, Ba presented the highest concentrations in pristine soils. It was concluded, that the environmental quality of agricultural soils within the Jaguari river basin - SP was slightly changed for the given parameters. The results also pointed out for the utilization of U and As as indicators of potential contamination in soils. (author)

  5. Methodology for correlations between doses and detectability in standard mammographic images: application in Sao Paulo state

    International Nuclear Information System (INIS)

    Measurements using mammography units were performed in loco in 50 health establishments, randomly sampled from an equipment list of the Cadastro Nacional de Estabelecimentos de Saude (Health Establishments Brazilian Catalog). For the measurements six phantoms were utilized to establish different quality criteria and to evaluate doses in different breast thicknesses. Two different methods of measuring average glandular doses (AGD) were applied, and measurements of entrance surface doses (ESD) were also realized, in order to obtain mean values to Sao Paulo State. A study relating distribution and properties of different mammography trademarks with doses was performed. The sensitometry of processors allowed a quantification of the film-processing contrast index, Ag, establishing a state mean value. The phantom images allowed the evaluation of detection limits of structures as microcalcifications, fibers, and masses, and state mean values were established for: spatial resolution (on surface and glandular breast position); image contrast; and detection expert ability from phantom images in two situations: before knowing the image targets and after viewing of a target map. Then, the results were compared to target detections in laboratory environment. Based on dose results, Ag, image contrast, maximum contrast, and detection ratio, a relationship between them was determined. The results show that, in Sao Paulo State, mean glandular doses were lower than reference levels considering the Wu method, and close to or above reference levels for ail phantoms considering the Dance method. The ESD was always close to or above reference levels. The Ag presented a mean value of (10,42 ± 0,20) for Sao Paulo State, and the image contrast was lower than the required limits established by the phantom manufacturers. The high contrast resolution showed that mammography units presented the expected values of line pair per mm in the State. The detectability evaluation of local experts was

  7. Elemental composition evaluation in lichens collected in the industrial city of Sao Mateus Sul, Parana, Brazil

    International Nuclear Information System (INIS)

    In this study, Canoparmelia texana lichenized fungi species was used as a passive biomonitor of the atmospheric pollution from the industrial city of Sao Mateus do Sul, PR, Brazil. Lichen samples collected from tree barks were cleaned, freeze-dried and analyzed by neutron activation analysis. Comparisons were made between the element concentrations obtained in lichens from this city and that from a clean area of Atlantic Forest in Intervales Park, SP. The high concentrations of elements As, Ca, Co, Cr, Fe, Hf, Sb, and Th found in lichens could be attributed to the emissions from a ceramic and an oil shale plants. (author)

    Ponte Nova reservoir, located in the upper basin of the Tiete River in the southern region of Sao Paulo State, covers an area of 25.7 km{sup 2} and drains an area of 320 km{sup 2}. It was built in 1972 to control the rivers flow in the Metropolitan Region of Sao Paulo (MRSP) and water supply. A 30 cm sediment core was collected in the dam in August 2014, sliced at every 2.5 cm. Instrumental neutron activation analysis (INAA) was applied to the sediment samples to determine some major (Fe, K and Na), trace (As, Ba, Br, Co, Cr, Cs, Hf, Rb, Sb, Sc, Ta, Tb, Th, U and Zn) and rare earth (Ce, Eu, La, Lu, Nd, Sm, Tb and Yb) elements. The enrichment factor (EF) and Igeo were applied to the results by using NASC (North American Shale Composite) as reference values for sediment contamination index assessment. An EF>1.5 was obtained for As, Hf, Rb, Ta, Th, U, and rare earths Ce, Eu, La, Nd and Sm when NASC values were used, but only for Br, when the last layer concentration values were used as reference values. Similar results were obtained for the Igeo index. For semi-metal As and metals Cr and Zn concentration values were compared to oriented values from Environmental Canada (TEL and PEL) only Cr exceeded TEL value in some slices of the profile. These results may indicate that there is no anthropogenic contribution for the elements analyzed in this reservoir. Multivariate statistical analysis was applied to the results. (author)

    This study aimed to evaluate the contribution of anthropogenic pollution in hydroelectric reservoirs through a case study of the Sao Simao Hydropower. The literature relates the problem of eutrophication with the addition of nutrients (nitrogen and phosphorus) in excess, resulting in water pollution. Through data for both tributary rivers and the reservoir, it was found that the Sao Simao dam presents a framework for eutrophication. We made an analysis to see which tributary rivers were the main sources of nutrients released into the waters of the reservoir and a survey of possible human activities that are contributing to the intake of nutrients in these tributaries.

    Purpose: This paper introduces an approach to technology evolution analysis using patent information based on Subject-Action-Object(SAO) structures.Design/methodology/approach: First, SAO structures were extracted from patent documents and were cleaned. Second, several dimension-reduction techniques were used to generate technology topics. Then, the hierarchical relationships between technology topics were calculated based on patent clustering. Finally, technology evolution maps were drawn by adding a timeline.Findings: This approach can reveal technology evolution processes from multiple perspectives than other approaches.Research limitations: The semantic annotation of an SAO type is not very accurate and the semantic types of technology topics need to be enriched.Practical implications: The approach can be applied to draw technology evolution maps using different types of technology topics such as problem or solution.Originality/value: This approach offers an analytical dimension and more details than existing techniques, and it helps identify fundamental and emerging technologies more accurately and comprehensively.

    About 4000 X-ray images obtained with the Einstein Observatory are used to measure the 0.16-4.0 keV emission from 1545 B-type SAO stars falling in the about 10 percent of the sky surveyed with the IPC. Seventy-four detected X-ray sources with B-type stars are identified, and it is estimated that no more than 15 can be misidentified. Upper limits to the X-ray emission of the remaining stars are presented. In addition to summarizing the X-ray measurements and giving other relevant optical data, the present extensive catalog discusses the reduction process and analyzes selection effects associated with both SAO catalog completeness and IPC target selection procedures. It is concluded that X-ray emission, at the level of Lx not less than 10 exp 30 ergs/s, is quite common in B stars of early spectral types (B0-B3), regardless of luminosity class, but that emission, at the same level, becomes less common, or nonexistent, in later B-type stars.

  17. Improvement of rice through somaculture and induced mutations in Sao Paulo State

    International Nuclear Information System (INIS)

    Rice (Oryza sativa L.) is one of the most important crops in Sao Paulo State, Brazil, from both the production and mainly the consumption standpoint. It is cultivated predominantly under upland conditions in areas that have high temperature and humidity, excellent environment for rapid spreading of the blast disease (Pyricularia grisea). The objective of this research was to induce mutations in connection with somaculture, for resistance to blast and a high yield potential, retaining the other qualities of IAC 201, a commercial upland variety. Seeds were irradiated with 60Co gamma rays at 300, 350 and 400 Gy, and boots and seeds from M1 plants in the 300 Gy treatments were harvested for mutation in vitro and in vivo techniques. Selection was not done in M2 generation; panicles were harvested and the offsprings were evaluated in the M3 generation for blast reaction. From 10340 panicles screened, 267 lines were selected with a possible blast tolerance. In the M4 generation these populations were again evaluated for blast reaction and for agronomic traits. Fifty-three possible mutant lines with tolerance to blast were selected, with more than 15% increments in yield potential. From these lines it is expected that at least one will be released in the near future as a new, resistant upland rice cultivar for Sao Paulo State, Brazil. (author)

    Full Text Available OBJECTIVE: To analyse recent trends in oral cancer mortality, focusing specifically on differences concerning gender and race. METHODS: Official information on deaths and population in the city of Sao Paulo, 2003 to 2009, were used to estimate mortality rates from oral cancer (C00 to C10, International Classification of Diseases, 10th Revision, adjusted for age and stratified by gender (females and males and race (blacks and whites. The Prais-Winsten auto-regression procedure was used to analyse the time series. RESULTS: During the study period, 8,505 individuals living in the city of Sao Paulo died of oral cancer. Rates increased for females (rate of yearly increase = 4.4%, 95%CI 1.4;7.5, and levelled off for men, which represents an inversion of previous trends among genders in the city. Increases were identified for blacks, with a high rate of yearly increase of 9.1% (95%CI 5.5;12.9, and levelled off for whites. Oral cancer mortality in blacks almost doubled during the study period, and surpassed mortality in whites for almost all categories. CONCLUSIONS: Mortality presented a higher increase among women than in men, and it doubled among backs. The surveillance of trends of oral cancer mortality across gender and racial groups may contribute to implementing socially appropriate health policies, which concurrently reduce the burden of disease and the attenuation of unfair, avoidable and unnecessary inequalities in health.

    Full Text Available Background: Simvastatin (SMV is one of the cholesterol-lowering pharmacological drugs. Recent studies demonstrate that it has a bone stimulatory effect. The present study was designed to investigate the effect of SMV along with collagen membrane on osteoblast-like SaOS-2 cells and also to standardize the dosage of SMV to be incorporated into the collagen membrane to achieve regeneration. Materials and Methods: SMV at doses of 0.5, 1, 1.5, and 2 mg was incorporated into the collagen membrane and cell metabolism was assessed by (3-[4,5-dimethylthiazolyl-2]-2,5-diphenyltetrazolium bromide (MTT assay for 24 h. Results: SMV enhanced cell metabolism dose dependently at 24-h time and the maximum effect was obtained at a concentration of 1.5 mg of SMV. Conclusion: These results indicate that collagen with 1.5 mg SMV exhibits positive effect on cell metabolism of human osteoblast-like SaOS-2 cells.

  20. High resolution spectroscopy of the high latitude rapidly evolving post-AGB star SAO 85766 (= IRAS 18062+2410)

    SAO 85766 (b = +20o) is an IRAS source with far-infrared colours similar to planetary nebulae. According to the HDE catalogue, its spectrum in 1940 was that of an A5 star. The UV fluxes and colours derived from data obtained by the TD1 satellite in 1972 also indicate that SAO 85766 was an A-type supergiant at that epoch. However, high resolution spectra of SAO 85766 obtained in 1993 in the wavelength interval 4350Ä to 8820Ä shows that now it is similar to that of an early B type post-AGB supergiant. In addition to the absorptions lines typical of a B1I type star, the spectrum of SAO 85766 is found to show numerous permitted and forbidden emission lines of several elements, typically observed in the spectra of young high density low excitation planetary nebulae. From an analysis of the absorption lines we have estimated Teff=22000+/-500 K, log g=3.0+/-0.5, xi t=15+/-2km s-1 and [M/H]=-0.6. Carbon is found to be strongly underabundant ([C/Fe] = -1.0), similarly to what has been observed in other high galactic latitude hot post-AGB stars. The underabundance of carbon and metals, high galactic latitude, high radial velocity (46 km s-1), the presence of planetary nebula type detached cold circumstellar dust shell and also the presence of low excitation nebular emission lines in the spectrum indicate that SAO 85766 is a low mass star in the post-AGB stage of evolution. The above mentioned characteristics and the variations observed in the spectrum of SAO 85766 suggest that it has rapidly evolved during the past 50 years and it is now in the early stages of the planetary nebula phase. The central star may just have become hot enough to photoionize the circumstellar envelope ejected during the previous AGB phase. >From an analysis of the nebular emission lines we find Te=10000+/- 500K and Ne=2.5 104 cm-3. The nebula also shows an abundance pattern similar to that of the central star. The rapid post-AGB evolution of SAO 85766 appears to be similar to that observed in the

    The Metropolitan Area of Sao Paulo is affected by high aerosol concentrations, which contain a large fraction of organic material. Up to date, not much is known about the composition and origin of the organic aerosol in this city. We present the first source apportionment of the carbonaceous aerosol fraction in Sao Paulo, using stable (13C) and radioactive carbon isotopes (14C). 14C provides a clear-cut distinction between fossil sources, which contain no 14C, and contemporary sources such as biofuels, biomass burning, or biogenic sources, which contain a typical contemporary 14C/12C ratio. 13C can be used to distinguish C3 plants, such as maize and sugarcane, from C4 plants. This can help to identify a possible impact of sugarcane field burning in the rural areas of Sao Paulo State on the aerosol carbon in the city. In the first part of the study, we compare two tunnel studies: Tunnel 1 is frequented only by light duty vehicles, which run mainly on mixtures of gasoline with ethanol (gasohol, 25% ethanol and 85% gasoline) or hydrated ethanol (5% water and 95% ethanol). Tunnel 2 contains a significant fraction of heavy-duty diesel vehicles, and therefore the fraction of biofuels in the average fleet is lower. Comparison of 14C in organic and elemental carbon (OC and EC) shows that in both tunnels there is no significant contribution of biofuels to EC. Combusting ethanol-gasoline fuels in a vehicle engine does apparently not result in significant EC formation from ethanol. Biofuels contribute around 45% to OC in Tunnel 1 an only 20% in Tunnel 2, reflecting a strong impact of diesel vehicles in Tunnel 2. In the second part of the study we conduct a source apportionment of ambient aerosol carbon collected in a field study during winter (July-August) 2012. Ambient EC has two main sources, vehicular emissions and biomass burning. We estimate a contribution of vehicular sources to EC of roughly 90% during weekdays and 80% during weekends, using the 14C values measured in

    The objective of this article is to evaluate the coverage and the economic impact of the Federal Government Program Aid Gas (Auxilio Gas) , started in the year of 2002. The evaluation covers only the state of Sao Paulo, using as source the Research of Familiar Budgets of IBGE 2002/2003. To evaluate the coverage of 'Aid-Gas' the targeted population is compared with the population that effectively received the benefit. To evaluate the economic impact of the program a test of significance of dummy variable that differentiate weight gas consumption on income for those attended by the program, controlled by Working-Leser function that models the covariates of gas expenses. A low coverage of the program was evidenced, only 32,098 families had received the benefit (4,01%) out of 786.929 families targeted group, those with per capita income was inferior the half minimum wage. The economic impact had mixed results. In one hand program beneficiaries would spend a larger percentage of income with gas consumption than those not reached; on the other hand, they would have access larger quantities of the product. If the food consumption and the gas consumption are correlated, and the families not benefited by the program are rationed, it is possible to confirm that the introduction of the program would increase welfare of families.

    Artificial and natural radionuclides are commonly found in several compartments of the earth's crust. Some mushroom species have a high capacity to absorb radionuclides and toxic elements from the soil. Diet is considered as one of the main routes of radioactive contamination. Therefore, radioactivity measurements in the environment and in food are extremely important to monitor the radiation levels that human can be exposed to either directly or indirectly. Environmental bio monitoring has demonstrated that diverse organisms such as crustaceans, fish and mushrooms are useful when evaluating both the contamination and the quality of the ecosystems. There are actually several radionuclides that can be accumulated in mushrooms, including {sup 40}K, {sup 137}Cs, {sup 232}Th and {sup 238}U. There are few studies in the Southern hemisphere countries, on the natural and artificial radioactivity levels in mushrooms. The present study evaluated {sup 40}K, {sup 137}Cs, {sup 232}Th and {sup 238}U in commercialized edible mushrooms in the state of Sao Paulo, Brazil. The edible mushroom samples were acquired in different commercial establishments in the Sao Paulo metropolitan region, specifically in Municipal Markets. Some samples were acquired directly from producers located in the cities of Mogi das Cruzes, Mirandopolis, Suzano and Juquitiba. About 400g were collected for each edible mushroom species, which included Agaricus sp, Pleurotus sp and Lentinula sp species. All the samples were prepared and stored in polyethylene bottles for approximately 35 days, so that secular equilibrium could be established before counting. The {sup 40}K, {sup 137}Cs, {sup 232}Th and {sup 238}U gamma activities were measured by gamma spectrometry. The equipment consisted of a Hyper pure Germanium detector connected to an electronic system. The detector efficiency was obtained from measurements of reference materials: IAEA-300, IAEA-327 and IAEA-375. The results for the specific activities

    Vehicular emissions in megacities such as Sao Paulo and Rio de Janeiro are increasingly becoming a global issue. The São Paulo Metropolitan Area (SPMA), located in Southeast of Brazil, is a megacity with a population of 18 million people, with 7 million cars and large-scale industrial emissions. Rio de Janeiro is also a large city with different meteorology than São Paulo. All cars in Brazil runs gasohol, with 23% ethanol in gasoline, and for the last 10 years, flex cars that can run on gasohol, ethanol or any mixture dominate the market. Overall ethanol accounts for about 30-40% of fuel burned in both cities. To improve the understanding of vehicular emission impacts on aerosol composition and life cycle in these two large megacities a source apportionment study, combining online and offline measurements, was performed. Aerosols were collected for one year to capture seasonal variability at 4 sites in each city, with inorganic and organic aerosol component being sampled. Organic and elemental carbon were measured using a Sunset Laboratory Dual Optics (transmission and reflectance) Carbon Analyzer and about 22 trace elements has been measured using polarized X-Ray Fluorescence (XRF). Aerosol mass and black carbon were also measured, as well as trace gases to help in aerosol source apportionment. In Sao Paulo, the average PM2.5 mass concentration obtained varied from 9.6 to 12.2 μg m-3 for the several sites, and similar concentrations were measured in Rio de Janeiro. At all sites, organic matter (OM) has dominated fine mode aerosol concentration with 42 to 60% of the aerosol mass. EC accounted for 21 to 31% of fine mode aerosol mass concentration. Sulfate accounted for 21 to 26% of PM2.5 for the sites. Aerosol source apportionment was done with receptor analysis and integration with online data such as PTR-MS, Aethalometers, Nephelometers and ACSM helped to apportion vehicular emissions. For the 8 sites operated in Sao Paulo and Rio de Janeiro, vehicular

The main recharge process is assumed to be the infiltration of rain water in the aquifer outcrop area. The progressive confining conditions with the increasing depth of the top of the aquifer layer makes the ground water temperature slowly greater. The recent magnesium and sodium bicarbonated waters changes first to sodium bicarbonated and then to sodium chloride-sulfated waters which are oldest found out in the research area(around 30.000 years ago). The mean Darcy permeability estimated on basis of 14C and hydraulic gradient data is 2.6x10-5 m/s. 9 maps (author)

    Geothermal exploration and development has been under way on Sao Miguel Island, Azores since 1975. This work had been restricted to the Fogo volcano, one of three dormant silicic volcanic centers on the island. The USGS in 1982 and 1983 conducted reconnaissance natural-source audio-magnetotelluric (AMT) surveys of all three silicic centers to evaluate the potential for geothermal systems at each and to demonstrate the utility of the method in areas of difficult terrain. Results on Fogo showed a low resistivity trend extending from the present production area upslope to the caldera boundary. The upper part of this trend is the upwelling zone of a thermal plume which supplies the production area. Further exploration and drilling are now planned for this area.

  16. Compliance with technical standards for radiological protection at radiation therapy services in Sao Paulo State, Brazil

    International Nuclear Information System (INIS)

    Radiation therapy services provide essential therapeutic procedures for cancer, one of the main causes of population morbidity and mortality. Despite their importance in the health system and their potential risks due to the use of ionizing radiation, there are few studies on such services. We evaluated compliance with technical standards for radiological protection in radiation therapy services in Sao Paulo State, Brazil. Forty-nine services were studied in 2000 through interviews with technical staff. Typologies of performance profiles focusing on structure and process variables were constructed and services compared. Important differences were observed in the services' positions in the health care system, level of complexity, and geographic distribution, with better average performance in structural conditions but very inadequate performance in patient protection, indicating the need for more effective health surveillance.

    International Nuclear Information System (INIS)

    The investigation reported in this dissertation has been divided in two parts. The first part was made to carry out an independent calibration of a Raman LIDAR system for water vapor in the CLA installed using a methodology that was developed at Howard University, based on a careful analysis of the efficiency of the optical system components aimed at determining the efficiency and displaying the spectral response of the system. After this study, which led to a better understanding of the eld of instrumental system, the second part, presents a preliminary study of the optical properties of aerosols in the troposphere by evaluating parameters such as, for example, the vertical profiles of aerosol extinction, SR and LR, using a mobile Raman LIDAR system developed by Raymetrics LIDAR Systems, during campaigns conducted in some research institutes in the State of Sao Paulo.

    International Nuclear Information System (INIS)

    To establish a Market Basket of Sao Paulo state seventy-one foods, with a mean consumption of more than 2 g day-1 per person, were grouped into 30 food categories. The food groups were: cereals, leguminous, leafy vegetables, fruity vegetables, tuberous vegetables, tropical fruits, other fruits, flours, pastas, breads, biscuits, prime grade beef, standard grade beef, pork meats, other meats, poultry, milk/cream, other dairy products, sugars, sweets, salts, sauces, oils, fats, alcoholic beverages, non-alcoholic beverages, coffee, ready-made dishes, saltwater and freshwater fishes. Information about individual food consumption was obtained from a recent national household food budget survey 'POF 2002-2003' conducted by the Brazilian Institute for Geography and Statistics from July 2002 to June 2003. Sampling and kitchen preparation of foods were carried out in restaurants of the University of Sao Paulo. Each food item was individually prepared table-ready. Foods of the same group were mixed, homogenized, pulverized and analyzed for the determination of Ca, Cr, Fe, K, Na and Zn concentrations by Instrumental Neutron Activation Analysis. Average daily intake of each element was calculated by multiplying the element concentration in the food by the corresponding weight of the ready-to-consume food group. The contribution of each food group to the total daily intake of elements by the ready-to-consume food groups of the Market Basket was evaluated. The food groups representing the highest contributions were salts: 79% Na; breads: 37% Fe and 46% Cr; cereals: 19% Zn and milk/cream: 58% Ca and 24% K. (author)

    The cosmogenic radionuclide {sup 7}Be (T{sub 1/2} = 53.3 d), produced in the upper atmosphere by cosmic ray spallation of oxygen and nitrogen, is one of the cosmogenic radionuclides that can be used as tracer for heavy metals and pollutants in the environment, tracer of soil erosion and sedimentation in lakes, among other examples. Their subsequent deposition to the land surface occurs as both wet and dry fallout, although it has been demonstrated that {sup 7}Be fallout is primarily associated with precipitation. There is limited data on the concentration of {sup 7}Be in rainfall and in particulate in the Southern Hemisphere and in Brazil, compared with data from the Northern Hemisphere. This paper presents the results obtained of {sup 7}Be concentrations measured from April 2011 to June 2013, in samples of air at ground level, each fifteen days, and rainfall in all the rainy events that occurred at Instituto de Pesquisas Energeticas e Nucleares (IPEN), which has its campus located in the city of Sao Paulo, state of Sao Paulo, Brazil. The concentrations of {sup 7}Be were measured by non-destructive gamma-ray spectrometry using an extended range closed-end coaxial Be-layer HPGe detector with 25% relative efficiency and associated electronic devices and live counting time varying from 100,000 s to 300,000 s. The results obtained of {sup 7}Be in particulate and in rainfall were correlated to seasons, precipitation, temperature and sunspot number. The higher values obtained for the concentrations were in spring and summer time presenting good correlations with the amount of precipitation and sunspot number and a clear seasonal variation.

    Tiete River, with 1100 km of extension, is one of the most economically important river of the state of Sao Paulo, Brazil and throughout its length can be found reservoirs formed by damming its waters. This river is considered one of the most polluted rivers in the world, especially when it passes through the city of Sao Paulo. As a result of pollution observed since the 1950's, a project was established with the aim of evaluating the historic concentration of the trace elements As, Ba, Br, Ca, Ce, Co, Cr, Cs, Eu, Fe, Hf, La, Lu, Na, Nd, Rb, Sb, Sc, Sm, Ta, Tb, Th, U, Yb and Zn (mg.kg{sup -1}), in sediment cores dated by {sup 210}Pb method, sampled is several points of the river, since its source in Salesopolis up the mouth, on the Parana River. This work presents the results obtained by the trace elements above determined in two sediment cores collected in reservoirs in the city of Salesopolis and Pirapora do Bom Jesus. The analytical techniques used for the analysis were instrumental neutron activation analysis and gross beta measurement, respectively. The results obtained for the elements Br, Ce, Cr, Cs, Eu, Nd, Sb, Sm, Th and U are higher than the values of Upper Continental Crust and the sedimentation rate obtained for the reservoir in Salesopolis, 1.53 cm.y{sup -1}, suggest silting processes. The enrichment factor and the geo-accumulation index were used to assess the presence of anthropogenic sources of pollution. Document available in abstract form only. (authors)

    Inorganic polyphosphate (polyP) is a physiological energy-rich polymer with multiple phosphoric anhydride bonds. In cells such as bone-forming osteoblasts, glycolysis is the main pathway generating metabolic energy in the form of ATP. In the present study, we show that, under hypoxic culture conditions, the growth/viability of osteoblast-like SaOS-2 cells is not impaired. The addition of polyP to those cells, administered as amorphous calcium polyP nanoparticles (aCa-polyP-NP; approximate size 100 nm), significantly increased the proliferation of the cells. In the presence of polyP, the cells produce significant levels of lactate, the end product of anaerobic glycolysis. Under those conditions, an eight-fold increase in the steady-state level of the membrane-associated carbonic anhydrase IX is found, as well as a six-fold induction of the hypoxia-inducible factor 1. Consequently, biomineral formation onto the SaOS-2 cells decreases under low oxygen tension. If the polyP nanoparticles are added to the cells, the degree of mineralization is enhanced. These changes had been measured also in human mesenchymal stem cells. The assumption that the bicarbonate, generated by the carbonic anhydrase in the presence of polyP under low oxygen, is deposited as a constituent of the bioseeds formed during initial hydroxyapatite formation is corroborated by the identification of carbon besides of calcium, oxygen and phosphorus in the initial biomineral deposit onto the cells using the sensitive technology of high-resolution energy dispersive spectrometry mapping. Based on these data, we conclude that polyP is required for the supply of metabolic energy during bone mineral formation under physiological, hypoxic conditions, acting as a 'metabolic fuel' for the cells to grow.

  4. Mercury and selenium accumulation assessment in fish most consumed by Cubatao Community, Sao Paulo, Brazil

    International Nuclear Information System (INIS)

    High correlation between mercury (Hg) and selenium (Se) concentrations in fish organs is well known. In the present study, 58 fish samples of five fish species most commonly consumed by the Cubatao city population, Sao Paulo State, Brazil were analyzed. The Cubatao Estuary, located in southeastern Sao Paulo State, is an economically important area suffering severe environmental water quality problems due to industrial wastes, domestic sewage and solid residues. The waters of the bay suffer the impact of the immense industrial complex of Cubatao. In this study, Hg concentration in muscle, liver and kidney tissues and Se concentration in liver tissue from three predatory fish species: Macrodon ancylodon (Pescada), Menticirrhus americanus (Perna de Moca) and Micropogonias furnieri (Corvina) and two planctivorous species: Mugil liza (Tainha) and Sardella braziliensis (Sardinha) were determined. Mercury determination was performed using Cold Vapour Atomic Absorption Spectrometry (CV AAS) and selenium by Instrumental Neutron Activation Analysis (INAA). The muscle-Hg concentration variation (wet weight) was: (8 to 40 μg kg-1) - Sardinha; (12 to 62 μg kg-1) - Pescada; (3 to 23 μg kg-1) - Tainha; (43 to 184 μg kg-1) - Perna de Moca and (41 to 348 μg kg-1) - Corvina. The general concentration ranges of the analyzed elements in all species studied were (dry weight): muscle-Hg (13 to 1512 μg kg-1); liver-Hg (21 to 1804 μg kg-1); kidney-Hg 47 to 9912 μg kg-1) and liver-Se (2.10 to 43.00 mg kg-1). Se concentrations were higher than those of Hg in the liver. (author)

    Air pollution has been a frequent topic of research, due to the effects that it can cause on the health of living organisms, environment and climate. In order to identify pollution sources and their effects, biomonitoring has been studied due to its low cost and possibility of sampling in wide geographic areas. In this study for passive biomonitoring of air pollution levels at the Cidade Universitaria Armando Salles de Oliveira (CUASO), University of Sao Paulo campus, epiphytic lichens of Canoparmelia texana species were used. The lichens collected from tree barks at different sampling sites in the CUASO were cleaned, freeze-dried and ground for analyses. Lichen samples were analyzed by X - ray fluorescence spectrometry (XRFS) and neutron activation analysis (NAA). For XRFS, cylindrical pellets of samples were prepared to determine As, Br, Ca, Cl, Cr, Cu, Fe, K, Mn, Rb, S, Sr and Zn. For NAA, lichen sample aliquots along with synthetic elemental standards were irradiated both for short and long periods at the IEA-R1 nuclear research reactor. The induced activities were measured by a gamma ray spectrometer to determine As, Br, Ca Cd, Cl, Co, Cr, Cs, Cu, Fe, K, La, Mg, Mn, Rb, Sb, Sc, Se, U, V and Zn. The precision and accuracy of the results were evaluated by the analysis of certified reference materials (MRCs). Their results of relative errors and standard deviations were below 15% for most of the elements. The standardized difference or En score values were lower than |1| indicating satisfactory results. Replicate analyses of a lichen sample by XRFS and NAA, indicated good homogeneity of the sample for the elements determined. The lichen results showed that the mean concentrations of As, Br, Ca, Cd, Co, Cr, Cs, Rb, Sb, Se and U were higher in samples from CUASO than those from regions considered unpolluted. For Fe, K, La, S, V and Zn, they were of the same order of magnitude. The correlation study between the elements showed high correlation (r > 0.7) for elements

    Results of the dating of fossil human teeth excavated from a shelter in the surroundings areas of the Serra da Capivara National Park, Sao Raimundo Nonato, Piaui, Brazil are presented. This shelter was partially excavated to search for more data that could improve the archaeological context of the Garrincho's limestone hill sites, where the Toca do Gordo do Garrincho shelter provided two human teeth dated by conventional C-14 in (12,170 {+-} 40) yBP (years before present) and calibrated age (2 Sigma, 95% probability) 15,245-14,690 yBP (Beta 136204) [E. Peyre, C. Guerin, N. Guidon, I. Coppens, CR Acad. Sci. Paris, Sciences de la terre et des planetes/ Earth and Planetary Sciences 327 (1998) 335, ]. This region is challenging the classical theories about the peopling of America. In agreement with such theories the first human groups would have arrived in America, through Behring, only about 20,000 years ago. The site Toca do Boqueirao da Pedra Furada is a rock-shelter situated at the cliff that is the frontier between the Pre-Cambrian Sao Francisco plain and the Devonian-Permian highlands of the Maranhao-Piaui basin. It was excavated from 1978 till 1988 and presented a very consistent stratigraphy, with thousand of lithic implements and hearths [F.

    The main object of this paper was to study the concentration of deuterium (D) and Oxygen-18 ({sup 18} O) in the rain and river waters from the States of Minas Gerais, Sao paulo and Parana. Monthly samples were prepared and analysed at the Centro de Energia Nuclear na Agricultura (CENA-ESALQ-USP) with the use of CH-4 ({sup 18} O) and GD-150 (D) mass spectrometers of Varian-Mat. In order to correlate the D and {sup 18} O of the rain water the equation {delta}D = 9.22 + 7.17{delta}18 was found. Considering the three equations separately it was observed that the parameter a = {delta}D -b{delta}18 increases from the South to the North. For the Piracicaba River (city of Piracicaba only), the D and {sup 18} O relationship was expressed by {delta}D = -10.98 + 4.88{delta}18. The States of Minas Gerais and Sao Paulo can be divided according to the weight-average concentrations ({delta}18 m%{sub 0}). This division is not possible from Parana. Considering the average from the weight average concentration (annually and summer) for the three States, the annual average (D and {sup 18} O) is slightly richer than the summer average, showing the importance of the amount effect, mainly for the States of Minas Gerais and Sao Paulo. The rivers studied had little variation in the {sup 18} O concentrations with no definite periodicity. The rivers from the North of Minas Gerais are slightly richer in {sup 18} O than the rivers from the South. The waters from Rio Grande in the South of Minas Gerais State are poorer in {sup 18} O than the water of the same river in the `Triangle`region. The {delta}18% {sub 0} data for the rivers Grande, Parnaiba and Parana are very similar, so there is no way to compute the contribution of the first and the second rivers in the formation of the third.

    Here we present the spectropolarimetric observations of the radio loud active galaxy 3C 390.3 in the period 2009-2014 (24 epochs). The galaxy has been observed with the 6-meter telescope of SAO RAS using the SCORPIO spectropolarimeter. We explore the variability and lags in the polarized light of the continuum and broad H$\\alpha$ line. We give the Stokes parameters $Q, U$, degree of linear polarization $P$ and the position angle of the polarization plane, $\\varphi$, for 24 epochs. We find a small lag~(10-40 days) between the unpolarized and polarized continuum that is significantly smaller than the estimated lags for the unpolarized broad emission lines (lag(H$\\alpha$)$\\sim$138-186 and lag(H$\\beta$)$\\sim$60-79 days). This shows that the region of the variable polarized continuum is significantly smaller than the broad line region, indicating that a part of the polarized continuum is coming from the jet. The lag of the polarized light in the H$\\alpha$ line (89-156 days) indicates an additional component to the...

    Environmental Company of the State of Sao Paulo (CETESB), Brazil, is responsible for particulate matter measurements (PM) in the Metropolitan Area of Sao Paulo (MASP). However, there are few works with indoor measures for MASP. Therefore, the aim of this work is to investigate the PM in households in the MASP. The chosen households were there are aged people over 60 years old. The measurements were sampled during 24 hours using a Personal Cascade Impactor (SKC Cat No. 225-370), which the following aerodynamic diameters: 10.0 - 2.5 (A); 1.0 - 2.5 (B); 0.50 - 1.0 (C); 0.25 - 0.50 (D), and < 0.25 μm (E). Together the impactor, there is a Leland Legacy pump (SKC Cat No. 100-3002) with a flow of 9L/min. It was analyzed 56 households with average values of PM10 and PM2.5 of 30.7 and 23.4 μg/m3, respectively. On average, 76% of PM10 consists of PM2.5, percentage higher than the outdoor environment (60% - CETESB), and 43% of the PM2.5 consists of PM smaller than 0.25 μm. Among all households, there was no exceedance of thresholds national standards PM10 (120 μg/m3) and PM2.5 (60 μg/m3). However, 10.7% of residences exceeded the PM10 threshold of the World Health Organization (50 μg/m3) and 39.2% for PM2.5 (20 μg/m3). The cluster analysis grouped the measures in the houses in four profiles. In three of them were greater amount of mass in ultrafine particles (E), followed by coarse particles (A) with the minimum in C level. The maximum in E may be due to the high contribution vehicular and secondary aerosol outdoor environment. The secondary maximum in A may be due to particles ressuspension and also arising from outdoors. These three groups differ only by the amount of PM measured in the households; they represent high, medium and low PM concentrations. The fourth group has average concentrations, but it presents a different profile because its maximum is in the D rather than E. All data will be analyzed concerning the possible sources.

Among all households, there was no exceedance of thresholds national standards PM10 (120 μg/m3) and PM2.5 (60 μg/m3). However, 10.7% of residences exceeded the PM10 threshold of the World Health Organization (50 μg/m3) and 39.2% for PM2.5 (20 μg/m3). The cluster analysis grouped the measures in the houses in four profiles. In three of them were greater amount of mass in ultrafine particles (E), followed by coarse particles (A) with the minimum in C level. The maximum in E may be due to the high contribution vehicular and secondary aerosol outdoor environment. The secondary maximum in A may be due to particles ressuspension and also arising from outdoors. These three groups differ only by the amount of PM measured in the households; they represent high, medium and low PM concentrations. The fourth group has average concentrations, but it presents a different profile because its maximum is in the D rather than E. All data will be analyzed concerning the possible sources.

  12. Characterization of the brazilian alcohol program in the State of Sao Paulo: production costs to plants and distillery homogeneous groups

    International Nuclear Information System (INIS)

    The ethanol producing plants in the State of Sao Paulo present variation in scale of production, productivity and cost structure. This paper presents production costs and analyses the competitiveness of neat ethanol with respect to gasoline, for each of the eight homogeneous groups of distilleries in operation in the State of Sao Paulo. The study shows that, at prices of march 1986, there is a variation of operational costs in the range of 1.46 to 1.95 cruzados per liter of hydrous ethanol. The reference price, including operational costs and interest on capital, varies from 2.47 to 3.15 cruzados per liter. These prices do not consider subsidies given by the Government under the Brazilian National Alcohol Program. The price of hydrous ethanol in Barrel Equivalent of Oil goes from 33.3 to 43.1 american dollars, showing that ethanol is not currently competitive with gasoline. (author)

    Genetic methods based on PCR-restriction fragment length polymorphism (RFLP) are widely used for microbial species determination. In this study, we present the application of saoC gene as an effective tool for species determination and within-species diversity analysis for Staphylococcus genus. The unique sequence diversity of saoC allows us to apply four restriction enzymes to obtain RFLP patterns, which appear highly distinctive even among closely related species as well as atypical isolates of environmental origin. Such patterns were successfully obtained for 26 species belonging to Staphylococcus genus. What is more, tracing polymorphisms detected by different restriction enzymes allowed for basic phylogeny analysis for Staphylococcus aureus, which is potentially applicable for other staphylococcal species.

    The Sao Paulo Brasilia Pipeline (OSBRA) starts at the Planalto Refinery (REPLAN) and supplies gasoline, diesel oil and LPG to the mid-west region of Brazil. The pipeline is 786 kilometers long with diameter of 20 inches in its first segment and 178 kilometers with 12 inches in the second. The fuels are pumped by seven unmanned pump stations and are delivered to five tank farms. At first, these products were pumped into the pipeline in batches of diesel or LPG between gasoline batches. These sequences allowed the dilution of the mixtures generated between the two products during the pipeline transportation to the pure product tanks, keeping compliance to the former standards. The diesel/gasoline mixtures were diluted direct to pure product tanks and the LPG/gasoline mixtures were submitted to flashing in a vessel before dilution. In 2001, the National Petroleum Agency changed the LPG and diesel oil standards. This new regulation turned the OSBRA installations unable to dilute the whole mixture volume generated during pipeline transportation. Sending part of the mixture back to the Refinery turned a mandatory task, increasing the costs and making the LPG pipeline transportation unprofitable. To overcome this situation, a new product was developed - QINTER. The QINTER can be diluted in suitable rates either to diesel or gasoline keeping the compliance of these fuels to the new standards at the receiving tanks. The QINTER is currently pumped into the pipeline between the batches of diesel oil and gasoline. The standard solution to treat the mixture created between LPG and gasoline batches, a fractional tower, was studied but it showed to be of dubious profitability and it would compel changes to the existing working schedule time, from Monday to Friday (6:00 am to 10:00 pm) to a 24:00 h/day continuous work. An alternative project was developed. Three flash recirculation vessels were designed to allow the mixtures of LPG with vapor stream and gasoline with liquid stream

    The Metropolitan Area of São Paulo (MASP) is impacted by the emission of 7 million vehicles, being 85% light-duty vehicles (LDV), 3% heavy-duty diesel vehicles (HDV)s, and 12% motorcycles. About 55% of LDVs burn a mixture of 78% gasoline and 22% ethanol (gasohol), 4% use hydrous ethanol (95% ethanol and 5% water), 38% are flex-fuel vehicles that are capable of burning both gasohol and hydrous ethanol and 3% use diesel (diesel + 5% bio-diesel). The owners of the flex-fuel vehicles decide to use ethanol or gasohol depending on the market price of the fuel. Many environmental programs were implemented to reduce the emissions by the LDV and HDV traffic; the contribution from the industrial sector has been decreasing as the industries have moved away from MASP, due to the high taxes applied to the productive sector. Due to the large contribution of the transport sector to CO2, its contribution is important in a regional scale. The total emission is estimated in 15327 million tons per year of CO2eq (60% by LDV, 38% HDV and 2% motorcycles). Measurements of CO2 performed with a Picarro monitor based on WS-CRDS (wavelength-scanned cavity ringdown spectroscopy) for the years 2012-2013 were performed. The sampling site was on the University of Sao Paulo campus (22o34´S, 46o44´W), situated in the west area of the city, surrounded by important traffic roads. The average data showed two peaks, one in the morning and the other in the afternoon, both associated with the traffic. Correlation analysis was performed between the concentrations and the number of vehicles, as a proxy for the temporal variation of the CO2 emission. The highest concentration was 430 ppm at 8:00am, associated to the morning peak hour of vehicles and the stable condition of the atmosphere. The average concentration was 406 ±12 ppm, considering all measured data. According to official inventories from the Environmental Agency (CETESB), the emission of CO2 has increased 39% from 1990 to 2008, associated

    The Sao Roque Group is characterized by volcano-sedimentary sequences, in which deposition probably started in the late Paleoproterozoic. U-Pb dating by LA-MC-ICPMS of zircons extracted from predominantly equigranular monzogranites clasts from Morro Doce and Morro do Polvilho regions, yield paleoproterozoic ages of 2199 {+-}8.5 Ma and 2247 {+-}13 Ma, respectively. These represent the ages for the main source of granite for the metaconglomerates from the Boturuna Formation (basal unit of Sao Roque Group). Its polycyclic history is reinforced by the presence of inherited Archean zircons (2694 {+-}29 Ma) found within the clasts. Moreover, these clasts have also been affected by the Neoproterozoic overprinting event as indicated by their lower intercept Concordia ages. Sm-Nd isotope data for the main clast varieties from the Morro Doce metaconglomerates yield T{sub DM} ages of 2.6 to 2.7 Ga, demonstrating that these granites are the recycling products of an Archean crustal component. The metaconglomerate arkosean framework yields slightly lower {epsilon}{sub Nd(t)} values than those for the clasts, indicating that a younger and/or more primitive source also contributed to the Boturuna Formation.

    Caxias is an orogenic gold deposit in the Sao Luis cratonic fragment, which is correlated with the Rhyacian terranes of the West-African Craton. The deposit postdates peak metamorphism (estimated at 2100 ± 15 Ma) and is hosted in a shear zone that cuts across schists of the Aurizona Group (2240 ± 5 Ma) and the Caxias Microtonalite. The emplacement age of the microtonalite, as determined in this work by SHRIMP U-Pb zircon dating, is 2009 ± 11 Ma and represents a latest age magmatic event in the Sao Luis cratonic fragment. Older zircon age of 2139 ± 10 Ma is interpreted as due to inheritance from the older granitoid or volcanic suites (magmatic sources?) or to contamination during emplacement. Lead isotope compositions indicate that the Pb incorporated in ore-related pyrite was probably sourced from regional, orogenic calc-alkaline granitoids of ca. 2160 Ma. Hydrothermal sericite from Caxias yielded a {sup 40}Ar/{sup 39}Ar plateau age of 1990 ± 30 Ma, which combined with the emplacement age of the Caxias Microtonalite brackets the age of gold mineralization between 2009 ± 11 and 1990 ± 30 Ma.

    One strategy used for the regeneration of bone is the development of cell culture substrates and scaffolds that can control osteoblast proliferation and differentiation. In recent investigations, carbon nanotubes (CNTs) have been utilized as scaffolds for osteoblastic cell cultures; however, there are only a few reports describing the proliferation of osteoblastic cells on thin CNT films; in particular, the effects of serum concentration on cell proliferation have not been studied. In the present study, we prepared culture dishes with homogeneous thin or thick films of non-modified CNTs and examined the effect of serum concentrations on human osteoblastic cells (Saos-2) proliferation in these culture dishes. We demonstrated that the ratio of cell proliferation was strongly affected by the concentration of serum. Interestingly, single-walled carbon nanotube (SWNT) thin films were found to be the most effective substrate for the proliferation of Saos-2 cells in low concentrations of serum. Thus, thin SWNT films may be used as an effective biomaterial for the culture of Saos-2 cells in low serum concentrations.

    Studies on air pollution have intensified in recent years, due to the diversity of emissions and the effect caused to the health of populations. Consequently, several techniques have been investigated for air pollution evaluation and among them one that has gained considerable attention is that of biomonitoring. In this study chemical elemental levels in the atmosphere of Sao Paulo city were evaluated, by means of passive biomonitoring, using epiphytic Canoparmelia texana species, in order to compare between the results obtained in samples from different sites of Sao Paulo city and in a reference site of Ubatuba city, SP. Neutron activation analysis (NAA) procedure applied in the analyses consisted of irradiating aliquots of samples along with synthetic standards of elements in the nuclear reactor IEA-R1 for 16 hours under a thermal neutron flux of about 5.0 x 10{sup 12} n cm{sup -2} s{sup -1}, followed by gamma ray spectrometry for the determination of As, Br, Ca, Co, Cr, Cs, Fe, K, La, Rb, Sc, Se and Zn. Results obtained in the analyses of lichens samples in replicates presented good reproducibility indicating homogeneity of the prepared samples. The precision and accuracy of the results were evaluated by the analyses of certified reference materials IAEA-336 Lichen and INCT-TL-1 Tea Leaves. Results obtained in the reference materials presented, in general, good precision, with relative standard deviations between 0.4 and 14.8% and good accuracy with relative errors between 0.2 and 8.7%. In Sao Paulo city, the lichens were collected in the following sites: Parque Dom Pedro II, Congonhas, Cidade Universitaria, Lapa, Mooca, Morumbi, Nossa Senhora do O, Parque Ibirapuera, Pinheiros, Santana, Santo Amaro and Taboao da Serra. Element concentrations found in lichens indicated a great variability depending on the sites where the samples were collected. The results obtained in the lichens submitted to the cluster analysis indicated three groups of sampling sites

    The execution of the OSBAT 24{sup o}il pipeline rehabilitation project, comprising the substitution of a 30 km section of the 37 years old pipeline has become a real benchmark in the history of this kind of job. The pipeline is inserted in one of the most sensitive environmental areas of the Sao Paulo State - the last Environmental Protection Area of the Mata Atlantica . The growth of human presence in its surroundings during the last three decades, has caused the right-of-way to be totally confined by luxury housing developments, streets, highways and resorts, as well as by the local communities and their activities, schools, and commerce. The pipeline runs through the Serra do Mar unstable mountain range slopes, with sequences of very steep hills and ravines followed by swamps and rivers. The success of such a challenging project - assembling the new line in a narrow ROW with all its restrictions, where the old line was still in operation, and complying with the tight work schedule required by PETROBRAS, was only possible due to a carefully managed combination of: accurate planning, best engineering methods and equipment and experienced workforce, deeply integrated in a massive effort towards safety, environmental care and social responsibility.

  2. Cash Transfers and Mayoral Elections: The Case of Sao Paulo's Renda Mínima

    2015-08-01

    Full Text Available Several recently published studies analyze the effects of national conditional cash transfer (CCT programs, such as the Brazilian Bolsa Família and the Mexican Oportunidades, on presidential elections. Most of them show that these programs boost incumbents' electoral support among the poor. This research note is the first scholarly attempt to investigate this phenomenon at a lower-level unit of a federal state, by assessing the impact of a municipal cash transfer program on a mayoral election. Specifically, it investigates whether Renda Mínima, the cash transfer program of the city of Sao Paulo, affected beneficiaries' electoral behavior in favor of the incumbent candidate in the 2004 mayoral election. This note analyzes survey data from CEBRAP/IBOPE and shows that cash transfers did, indeed, affect beneficiaries' behavior in the predicted direction, but only in cases where they did not benefit from any other CCT program, such as the federal Bolsa Família or the São Paulo state Renda Cidadã. These results suggest that the pro-incumbent effect of CCT programs may be diluted by similar programs launched by governments at other tiers of a federation, even if they are led by the same party.

    Results of the recent polarimetric observations of distant comets C/2013 V4 (Catalina), C/2014 A4 (SONEAR), C/2010 S1 (LINEAR), C/2010 R1 (LINEAR), and 29P/Schwassmann-Wachmann 1 are presented together with analysis of their photometry and spectroscopy. Observations were carried out at the 6-m telescope BTA of the SAO RAS with the multi-mode focal reducer SCORPIO-2 from 2011 to 2015. Comets were observed in the range of heliocentric distances from 4.2 to 7.0 AU and phase angles from 4.9 to 9.4 degrees. The maps of intensity and linear polarization over the coma are derived. The comets observed show a considerable activity at heliocentric distances far exceeding a zone of water sublimation. Molecular emissions were only detected in the spectra of comet 29P/Schwassmann-Wachmann 1. The linear polarization of distant comets with a high level of activity is the first ever measured at the heliocentric distances larger than 5 AU. The degree of linear polarization (from -2 to -3.7%) for these comets is significantly higher (in absolute value) than the typical value of the whole coma polarization (about -1.5 %) at the minimum of negative polarization branch for close to the Sun comets.

  4. The acoustics for speech of eight auditoriums in the city of Sao Paulo

    2002-11-01

    Eight auditoriums with a proscenium type of stage, which usually operate as dramatic theaters in the city of Sao Paulo, were acoustically surveyed in terms of their adequacy to unassisted speech. Reverberation times, early decay times, and speech levels were measured in different positions, together with objective measures of speech intelligibility. The measurements revealed reverberation time values rather uniform throughout the rooms, whereas significant variations were found in the values of the other acoustical measures with position. The early decay time was found to be better correlated with the objective measures of speech intelligibility than the reverberation time. The results from the objective measurements of speech intelligibility revealed that the speech transmission index STI, and its simplified version RaSTI, are strongly correlated with the early-to-late sound ratio C50 (1 kHz). However, it was found that the criterion value of acceptability of the latter is more easily met than the former. The results from these measurements enable to understand how the characteristics of the architectural design determine the acoustical quality for speech. Measurements of ST1-Gade were made as an attempt to validate it as an objective measure of ''support'' for the actor. The preliminary diagnosing results with ray tracing simulations will also be presented.

    After the Chernobyl accident in 1986, high levels of the radionuclide accumulation in different foodstuffs and the environment have being reported. The potential of mushrooms to accumulate fallout radionuclides in their fruit bodies have been well recognized. Mushrooms can also accumulate toxic elements in general, including natural radionuclides. In Southern Hemisphere countries, especially in Latin America, there are a few studies on this subject. In Brazilian literature, there are no studies that determine the composition of natural and artificial radionuclides in edible mushrooms. The objective of this study was to measure of {sup 137} Cs and {sup 40}K activity in commercialized edible mushrooms in Sao Paulo, Brazil. The activity measurements were carried out by spectrometry gamma. The system detection efficiency was measured using the certified reference materials IAEA- 300 Marine Sediment and IAEA-375 Soil. The activities of {sup 13}'7Cs in the mushroom samples varied from 2.2 to 6.5 Bq kg{sup -1} for Pleurotus osteatus and Agaricus bisporus respectively. The {sup 40}K activities varied from 150 to 907 Bq kg{sup -1} for Pleurotus ostreatus and Lentinula edodes, respectively. (author)

    Large urban centers have a huge demand for electricity, for the needs of its residents, and a growing problem of management of solid waste generated by it, that becomes an public administrative and great social problem. The correct disposal of solid waste generated by large urban centers is now one of the most complex engineering problems involving logistics, safety, environment, energy spent among other tools for sound management of municipal solid waste (MSW). This study was carried out a study of the use of incinerators and residue derived fuel and MSW with combined cycles, with the aim of producing thermal and mechanical energy (this later becomes electrical energy) and solid waste treatment in Sao Paulo. We used existing models and real plants in the European Union in this case, with the aim of making it the most viable and compatible with the current context of energy planning and resource today. A technical and economic feasibility study for a plant of this nature, using the scheme, is presented. It is expected a good attractiveness of using incinerators combined-cycle, due to its high efficiency and its ability to thermoelectric generation. (author)

  7. Business and politics in Sao Tome e Principe: from cocoa monoculture to petro-state

    International Nuclear Information System (INIS)

    While the islands of Sao Tome e Principe (STP) were once a leading cocoa producer, cocoa production is now relatively insignificant and the country is little known today outside the lusophone world. But STP could soon gain strategic and economic importance as its territorial waters are suspected to hold large quantities of crude oil. This article explores STP's shift away from domination by cocoa exports, narrating the decline and final collapse of the plantation economy and the country's slide towards overwhelming dependence on external assistance in the form of foreign aid and external debt. In this context, it calls STP an unviable state as its fledgling domestic economy fails to generate enough revenue to sustain its highly import-reliant consumption patterns. But it finds STP on the verge of another major transformation as it is likely to become a crude oil producer within a few years. In the course of this research, the authors came across major irregularities in the conduct of the country's oil policy and some of this information appears for the first time in the public domain. In this context, their research points to opportunities for rent-seeking and corrupt behaviour, which stem from access to foreign aid and natural resources. (author)

  8. The Sao Pedro do Sul granite, Portugal: hydrogeochemistry related to the exploration of uranium

    International Nuclear Information System (INIS)

    The Sao Pedro do Sul granite in the north-central part of Portugal is highly radioactive but is not affiliated with any known uranium mineralization. This setting therefore provided an interesting case study for the hydrogeochemistry of uranium. Spring, tap and stream water samples were collected and analysed for pH, Ec, Na, K, Ca, Mg, Cl, SO4, HCO3, H4SiO4, PO4, NO3, DOC, F, U, Sr and Ba. Univariate and multivariate statistical techniques were applied to gain an understanding of the important factors that influence the water composition. Evaporation appeared to dominate the chemistry of the waters. Faults and the deeper weathering of the granite are also reflected in the water composition, especially in the behaviour of the pH, HCO3, F and H4SiO4. The U concentrations are low and do not show any interesting groupings. The combined results concur with the absence of known outcropping mineralizations, and also indicate that the presence of hidden ore bodies is unlikely. (orig.)

  9. Precambrrian continental crust evolution of southeastern Sao Paulo state-Brazil: based on isotopico evidences

    International Nuclear Information System (INIS)

    The focussed area comprises five major different tectonic terranes separated by faults, which are named Alto Rio Grande Belt, Socorro-Guaxupe Nappe, Sao Roque, Embu and Costeiro Domains. The geological and geochronological history of these terranes show that the metamorphic episodes of crust-forming occurred involving both mantle-derived magmas and reworking of continental material since 3.4 Ga until 600 Ma. The post-tectonic granitic activities occurred within 1000-500 Ma range and in general, the rocks are progressively younger from the Socorro-Guaxupe Nappe (1000-850 Ma) in the NW towards the Costeiro Domain (550 Ma) in the SE. The Sr and Pb isotopic evidences, together with geological and geophysical informations, suggest that the proportions of the rock-forming processes through the geological time are: Archean, 10%; Lower Proterozoic, 10%; Middle Proterozoic, 38%; Late Proterozaic, 42%. Although the Mid and Late Proterozoic time were a period of a large amount of rocks were formed, they were not a major crustforming period, because these rocks are mainly constituted by recycled continental crust material. In our view, at end of the Early Proterozoic time, at least 85% of continetal crust, in this area, has accreted and differentiate. During the Middle and Late Proterozoic the continental crust grew at small rate. (author)

    Full Text Available We investigated the effect of bioglass (bioactive glass on growth and mineralization of bone-related SaOS-2 cells, encapsulated into a printable and biodegradable alginate/gelatine hydrogel. The hydrogel was supplemented either with polyphosphate (polyP, administered as polyP • Ca2+-complex, or silica, or as biosilica that had been enzymatically prepared from ortho-silicate by silicatein. These hydrogels, together with SaOS-2 cells, were bioprinted to computer-designed scaffolds. The results revealed that bioglass (nanoparticles, with a size of 55 nm and a molar ratio of SiO2 : CaO : P2O5 of 55 : 40 : 5, did not affect the growth of the encapsulated cells. If silica, biosilica, or polyP • Ca2+-complex is co-added to the cell-containing alginate/gelatin hydrogel the growth behavior of the cells is not changed. Addition of 5 mg/ml of bioglass particles to this hydrogel significantly enhanced the potency of the entrapped SaOS-2 cells to mineralize. If compared with the extent of the cells to form mineral deposits in the absence of bioglass, the cells exposed to bioglass together with 100 µmoles/L polyP • Ca2+-complex increased their mineralization activity from 2.1- to 3.9-fold, or with 50 µmoles/L silica from 1.8- to 2.9-fold, or with 50 µmoles/L biosilica from 2.7- to 4.8-fold or with the two components together (100 µmoles/L polyP • Ca2+-complex and 50 µmoles/L biosilica from 4.1- to 6.8-fold. Element analysis by EDX spectrometry of the mineral nodules formed by SaOS-2 revealed an accumulation of O, P, Ca and C, indicating that the mineral deposits contain, besides Ca-phosphate also Ca-carbonate. The results show that bioglass added to alginate/gelatin hydrogel increases the proliferation and mineralization of bioprinted SaOS-2 cells. We conclude that the development of cell-containing scaffolds consisting of a bioprintable, solid and cell-compatible inner matrix surrounded by a printable hard and flexible outer matrix containing

    We present thirteen epochs of near-infrared (0.8-5 microns) spectroscopic observations of the pre-transitional, "gapped" disk system in SAO 206462 (=HD 135344B). In all, six gas emission lines (Br(alpha) , Br(gamma), Pa(beta), Pa(delta), Pa(epsilon), and the 0.8446 microns line of O I) along with continuum measurements made near the standard J, H, K, and L photometric bands were measured. A mass accretion rate of approximately 2 x 10(exp 8)Solar Mass/yr was derived from the Br(gamma) and Pa(beta) lines. However, the fluxes of these lines varied by a factor of over two during the course of a few months. The continuum also varied, but by only approx.30%, and even decreased at a time when the gas emission was increasing. The H I line at 1.083 microns was also found to vary in a manner inconsistent with that of either the hydrogen lines or the dust. Both the gas and dust variabilities indicate significant changes in the region of the inner gas and the inner dust belt that may be common to many young disk systems. If planets are responsible for defining the inner edge of the gap, they could interact with the material on time scales commensurate with what is observed for the variations in the dust, while other disk instabilities (thermal, magneto-rotational) would operate there on longer time scales than we observe for the inner dust belt. For SAO 206462, the orbital period would likely be 1-3 years. If the changes are being induced in the disk material closer to the star than the gap, a variety of mechanisms (disk instabilities, interactions via planets) might be responsible for the changes seen. The He I feature is most likely due to a wind whose orientation changes with respect to the observer on time scales of a day or less. To further constrain the origin of the gas and dust emission will require multiple spectroscopic and interferometric observations on both shorter and longer time scales that have been sampled so far.

  13. Proposal of reference concentration values for metals and metalloids in limnic and fluvial sediments of Tiete River, Sao Paulo State, Brazil

    International Nuclear Information System (INIS)

    This project represents the first efforts in Brazil in the proposition and establishment of reference concentration values for metals and metalloids in limnic and fluvial sediments. The selected study site is the Tiete river basin (Sao Paulo state, southeast region), a watershed which is under significant environmental impact and degradation since the onset of the Brazilian revolution at early-mid 50's. In order to consolidate the analytical values 1,100 analyses were performed encompassing 95 sampling points in 29 municipalities, from the upper stream parts of the river down to its mouth at the Parana river, covering an extension of approximate 800 km. Sediment samples were collected in small streams and rivers as closest as possible to their upper reaches, as well as in rivers and reservoirs in locations minimally affected by human contamination. Samples were initially sieved for separation of the particles 3, HF, HClO4 and HCl). Chemical analyses were performed by induced coupled plasma atomic emission spectrometry for Cr, Ti, Zn, and V, and via atomic absorption spectrometry using conventional flame for Co, Cu, Ni and Pb, graphite furnace for Cd and Ag, hydride generation for As and Se, and cold vapor for Hg. U and Th were analysed by molecular absorption spectrophotometry using the chromogenic reagent Arsenazo III. The referent concentrations determined by this study showed significant differences with respect to the assumed global geological reference for some elements; differences were also detected among the concentrations of the same element from different basin regions and are attributed to differences in regional geochemical characteristics. As a consequence of these lithological variations, four different sets of reference concentration values are proposed valid to the different regions of the studied basin. This study also presents application of different sediment quality classifications models and potential ecological risk index for Bariri, Billings

    Environmental issues are of great importance when assessing the feasibility and priority installation of new developments in electric power generation. In this sense, fuzzy logic can help define the regions that have favorable characteristics for receiving certain forms of generation. This study sought to order for the State of Sao Paulo, four kinds of generation projects: those using municipal solid waste gasification, those which make use of landfill gas with a change in firing (to reduce emissions), thermoelectric plants (TEPs) to bagasse (with 15% straw) and Small Hydropower (SHP). Such an ordering considered not only the type of generation but also the allocation of projects in the four regions, defined by regional vocations as defined by the State Water Resources Plan (Annex III of the State Law No. 9.034/94): Agriculture, Conservation, In Industrialization and Industrial. As a result, the use of fuzzy sets allowed the creation of a ranking of the alternatives (which totaled 14 possibilities), based exclusively on the degree of interference in air quality resulting from the installation of every form of generation. Such information may help the decision-making governing bodies to establish priorities in order, thereby accelerating the process of installation and operation of projects for generating electricity.

    It is recognized that megacities have regional and global effects on climate, and that aerosols and Green House Gases (GHG) constitute the principal tracer of those effects. Such is the case in the Metropolitan Area of Sao Paulo (MASP), one of the largest mega-cities in the world. MASP has a population of almost 20 million inhabitants. The main source of air pollution is the transport sector. In this region, there are approximately 6.5 million passenger cars and commercial vehicles: 85% light duty, 3% heavy-duty diesel vehicles (diesel + 3% bio-diesel) and 12% motorcycles. Of the light duty vehicle, approximately 55% burn a mixture (v/v) of 78% gasoline with 22% ethanol (referred to as gasohol), 4% use hydrated ethanol (95% ethanol + 5% water), 38% flexible fuel vehicles capable of burning both gasohol as hydrated ethanol, and 2% use diesel. In average 50% of the fuel used in MASP is ethanol what brings the necessity of more studies to understand the formation of photochemical oxidants and secondary particles. According to the São Paulo State Environmental Protection Agency, 97% of carbon monoxide (CO), 85% of hydrocarbons (HC), 82% of nitrogen oxides (NOx), 36% of sulfur dioxide emitted, and 36% of all inhalable particulate matter (PM10) are emitted by the vehicular fleet. Concerning particles, 75% of the Fine Particle Concentration is related to the burning of fuel, mainly diesel. The fine particles are composed of Organic Carbon (40%), Black Carbon (30%), ions (15%) and metals. It is known that the soot is warming the climate and is important to the radiative balance. Another important driver to the radiative balance, the CO2 is mainly emitted by the transport sector, which is responsible for 57% of its emission. A comprehensive project under development has the objective of determine the role of MASP as the source of gaseous and particle compounds to the atmosphere of the region and in a mesoscale perspective.

  17. Hydrobiological aspects of Paraibuna and Paraitinga dams. Sao Paulo, with emphasis on phytoplankton community

    International Nuclear Information System (INIS)

    The inland waters are less on the Earth's surface and are extremely important for the survival of living things, why the concern for quality increases daily. The dams Paraibuna and Paraitinga, located in Paraibuna city, state of Sao Paulo, totaling 224 km2 of extension of water surface, with the current function of generating electricity. In order to analyze the water quality of these dams, this paper presents a diagnostic physical, chemical, and biological, which was used in the phytoplankton community and calculation of quality indexes. Four samples were taken at nine sampling points distributed along the dams. The physical and chemical analysis of water showed low concentrations of nutrients such as nitrate (mean 0,42 ± 0,23 mg.L-1 and phosphate (-1). Most metals and trace elements analyzed were within the limit established by federal law. The element phosphorus (mean 0,0293 ± 0,0153 mg.L-1) is presented above the values established by CONAMA Resolution 357/05 (0,020 mg.L-1) on all sampling points in the month of May, but this fact did not seem to influence the phytoplankton amount. High levels of dissolved oxygen and transparency, low levels of turbidity, conductivity and dissolved solids, pH close to neutrality, together with high diversity and low dominance of phytoplankton, with a predominance of green algae, showed that the dams still retain features of aquatic environment preserved, which suffer little influence of anthropogenic factors. However, the presence, even at low densities, of cyanobacteria and the existence of plantations and livestock activities in the borders of these dams deserve special attention in terms of their correct management to not become harmful factors to the quality of those waters.

    Tobacco smoking is an important risk factor for the development of severe periodontitis.Recently, we showed that nicotine affected mineralized nodule formation, and that nicotine and lipopolysaccharide stimulated the formation of osteoclast-like cells by increasing production of macrophage colony-stimulating factor (M-CSF) and prostaglandin E2 (PGE2) by human osteoblastic Saos-2 cells. In the present study, we examined the effects of nicotine on the expression of matrix metalloproteinases (MMPs),tissue inhibitors of matrix metalloproteinases (TIMPs), the plasminogen activation system including the component of tissue-type plasminogen activator (tPA), urokinase-type PA (uPA), and PA inhibitor type 1(PAI- 1), α7 nicotine receptor, and c-fos. We also examined the effect of the nicotine antagonist D-tubocurarine on nicotine-induced expression of MMP-1. Gene expression was examined using real-time polymerase chain reaction (PCR) to estimate mRNA levels. In addition, expression of the MMP, TIMP, uPA, tPA, and PAI-1proteins was determined by Western blotting analysis. Nicotine treatment caused expression of MMP-1, 2, 3,and 13, but not MMP-14, to increase significantly after 5 or 10 d of culture; MMP-14 expression did not change through day 14. Enhancement of MMP-1 expression by nicotine treatment was eliminated by simultaneous treatment with D-tubocurarine. In the presence of nicotine, expression of uPA, PAI-1, or TIMP-1, 2, 3, or 4 did not change over 14 d of culture, whereas expression of tPA increased significantly by day 7. Nicotine also increased expression of the α7 nicotine receptor and c-fos genes. These results suggest that nicotine stimulates bone matrix turnover by increasing production of tPA and MMP-1, 2, 3, and 13,thereby tipping the balance between bone matrix formation and resorption toward the latter process.

  4. The SAO and Kelvin waves in the EuroGRIPS GCMS and the UK Met. Office analyses

    Directory of Open Access Journals (Sweden)

    M. Amodei

    Full Text Available We compare the tropical oscillations and planetary scale Kelvin waves in four troposphere-stratosphere climate models and the assimilated dataset produced by the United Kingdom Meteorological Office (UKMO. The comparison has been made in the GRIPS framework "GCM-Reality Intercomparison Project for SPARC", where SPARC is Stratospheric Processes and their Role in Climate, a project of the World Climate Research Program. The four models evaluated are European members of GRIPS: the UKMO Unified Model (UM, the model of the Free University in Berlin (FUB–GCM, the ARPEGE-climat model of the French National Centre for Meteorological Research (CNRM, and the Extended UGAMP GCM (EUGCM of the Centre for Global Atmospheric Modelling (CGAM. The integrations were performed with different, but annually periodic external conditions (e.g., sea-surface temperature, sea ice, and incoming solar radiation. The structure of the tropical winds and the strengths of the Kelvin waves are examined. In the analyses where the SAO (Semi-Annual Oscillation and the QBO (Quasi-Biennal Oscillation are reasonably well captured, the amplitude of these analysed Kelvin waves is close to that observed in independent data from UARS (Upper Atmosphere Research Satellite. In agreement with observations, the Kelvin waves generated in the models propagate into the middle atmosphere as wave packets, consistent with a convective forcing origin. In three of the models, slow Kelvin waves propagate too high and their amplitudes are overestimated in the upper stratosphere and in the mesosphere, the exception is the UM which has weaker waves. None of the modelled waves are sufficient to force realistic eastward phases of the QBO or SAO. Although the SAO is represented by all models, only two of them are able to generate westerlies between 10 hPa and 50 hPa. The importance of the role played in the SAO by unresolved gravity waves is emphasized. Although it exhibits some unrealistic features, the

    Signatures of the 11-year solar activity/irradiance cycle are observed in the Quasi Biennial Oscillation (QBO) of the lower stratosphere. At these altitudes, the QBO is understood to be the result of "downward control" exerted by the wave mean flow interactions that drive the phenomenon. It is reasonable then to speculate that the QBO is a natural conduit to lower altitudes of solar activity variations in radiance (SAV). To test this hypothesis, we conducted experiments with a 2D version of our Numerical Spectral Model that incorporates Hines' Doppler Spread Parameterization for small-scale gravity waves (GW). To account for the SAV, we change the solar heating rate on a logarithmic scale from 0.1% at the surface to 1% at 50 kin to 10% at 100 km. With the same GW flux, we then conduct numerical experiments to evaluate the magnitude of the solar activity irradiance effect (SAE) on the zonal circulation at low latitudes. The numerical results obtained show that, under certain conditions, the SAE is significant in the zonal circulation and does extend to lower altitudes where the SAV is small. The differences in the wind velocities can be as large as 5 m/s at 20 kin. We carried out two numerical experiments with integrations over more than 20 years: 1) With the QBO period "tuned" to be 30 months, of academic interest but instructive, the seasonal cycle in the solar forcing [through the Semi-annual Oscillation (SAO)] acts as a strong pacemaker to produce a firm lock on the period and phase of the QBO. The SAE then shows up primarily as a distinct but relatively weak amplitude modulation. 2) With the QBO period between 30 and 34 (or less than 30, presumably) months, the seasonal phase lock is weak compared with (1). The SAV in the seasonal cycle then causes variations in the QBO period and phase, and this amplifies the SAE to produce relatively large variations in the wind field. We conclude that, under realistic conditions as in (2), the solar seasonal forcing, with

    Background Over the last century the incidence of cutaneous melanoma has increased worldwide, a trend that has also been observed in Brazil. The identified risk factors for melanoma include the pattern of sun exposure, family history, and certain phenotypic features. In addition, the incidence of melanoma might be influenced by ethnicity. Like many countries, Brazil has high immigration rates and consequently a heterogenous population. However, Brazil is unique among such countries in that the ethnic heterogeneity of its population is primarily attributable to admixture. This study aimed to evaluate the contribution of European ethnicity to the risk of cutaneous melanoma in Brazil. Methodology/Principal Findings We carried out a hospital-based case-control study in the metropolitan area of Sao Paulo, Brazil. We evaluated 424 hospitalized patients (202 melanoma patients and 222 control patients) regarding phenotypic features, sun exposure, and number of grandparents born in Europe. Through multivariate logistic regression analysis, we found the following variables to be independently associated with melanoma: grandparents born in Europe—Spain (OR = 3.01, 95% CI: 1.03–8.77), Italy (OR = 3.47, 95% CI: 1.41–8.57), a Germanic/Slavic country (OR = 3.06, 95% CI: 1.05–8.93), or ≥2 European countries (OR = 2.82, 95% CI: 1.06–7.47); eye color—light brown (OR = 1.99, 95% CI: 1.14–3.84) and green/blue (OR = 4.62; 95% CI 2.22–9.58); pigmented lesion removal (OR = 3.78; 95% CI: 2.21–6.49); no lifetime sunscreen use (OR = 3.08; 95% CI: 1.03–9.22); and lifetime severe sunburn (OR = 1.81; 95% CI: 1.03–3.19). Conclusions Our results indicate that European ancestry is a risk factor for cutaneous melanoma. Such risk appears to be related not only to skin type, eye color, and tanning capacity but also to others specific characteristics of European populations introduced in the New World by European immigrants.

  7. Long-term decomposition of sugarcane harvest residues in Sao Paulo state, Brazil

    International Nuclear Information System (INIS)

    Crop residues returned to the soil are important to preserve fertility and sustainability. This research addressed the long-term decomposition of sugarcane post-harvest residues (trash) under reduced tillage, therefore field renewal was performed with herbicide followed by subsoiling and ratoons were deprived of interrow scarification. The trial was conducted in the northern Sao Paulo State, Brazil during four consecutive crops (2005–2008) where litter bags containing 15N-labeled trash were disposed in the field attempting to simulate two distinct situations: the previous crop trash (PCT) or residues incorporated in the field after tillage, and post-harvest trash (PHT) or the remains of plant-cane harvest. Decomposition rates regarding dry matter (DM), carbon (C), root growth, plant nutrients (N, P, K, Ca, Mg and S), lignin (LIG) cellulose (CEL) and hemicellulose (HCEL) contents were assessed for PCT (2005 ndash;2008) and for PHT (2006–2008). There were significant reductions on DM and C:N ratio due to C losses and root growth within the litter bags over time. The DM from PCT and PHT decreased 96% and 73% after four and three crops, respectively, and the higher nutrients release were found for K, Ca and N. The LIG, CEL and HCEL concentrations in PCT decreased 60%, 29%, 70% after four crops and 47%, 35%, 70% from PHT after three crops, respectively. Trash decomposition was driven mainly by residues biochemical composition, root growth within the trash blanket and the climatic conditions during the crop cycles. -- Highlights: ► Degradation of sugarcane previous or post-harvest trash (PCT or PHT) was evaluated. ► Dry matter and C decreased due to microbial and root growth within trash blankets. ► C:N ratio of PCT linearly decreased 23% per year during four consecutive crops. ► Lignin, cellulose and hemicellulose concentration averagely declined 54, 41 and 70%. ► PCT and PHT are long-term sources of C, K, Ca and N to the soil-plant system.

    The metropolis of Sao Paulo, with its 7940 Km² and over 20 million inhabitants, is increasingly being consolidated with disregard for the dynamics of its fluvial systems and natural limitations imposed by fluvial terraces, floodplains and slopes. Events such as floods and flash floods became particularly persistent mainly in socially and environmentally vulnerable areas. The Aricanduva River basin was selected as the ideal area for the development of the flood hazard analysis since it presents the main geological and geomorphological features found in the urban site. According to studies carried out by Anthropic Geomorphology approach in São Paulo, to study this phenomenon is necessary to take into account the original hydromorphological systems and its functional conditions, as well as in which dimensions the Anthropic factor changes the balance between the main variables of surface processes. Considering those principles, an alternative model of geographical data was proposed and enabled to identify the role of different driving forces in terms of spatial conditioning of certain flood events. Spatial relationships between different variables, such as anthropogenic and original morphology, were analyzed for that purpose in addition to climate data. The surface hydrodynamic tendency spatial model conceived for this study takes as key variables: 1- The land use present at the observed date combined with the predominant lithological group, represented by a value ranging 0-100, based on indexes of the National Soil Conservation Service (NSCS-USA) and the Hydraulic Technology Center Foundation (FCTH-Brazil) to determine the resulting balance of runoff/infiltration. 2- The original slope, applying thresholds from which it's possible to determine greater tendency for runoff (in percents). 3- The minimal features of relief, combining the curvature of surface in plant and profile. Those three key variables were combined in a Geographic Information System in a series of

    Features of the equatorial electrojet are studied at Sao Luiz (2.6°S, 44.2°W, inclination −0.25°) in eastern Brazil and Sikasso (11.3°N, 5.7°W, inclination 0.1°) in the western African sector. The stations are situated on either side of the lowest magnetic field intensity in the region of rapid changes in the declination. The daily variations of X at the two stations are almost similar with the peak around noon with maximum values during equinoxes and minimum values during J-solstices. Daily variations of Y differ with the maximum deviation of about −35 nT around noon at Sao Luiz and much smaller value of about −10 nT around 14 h LT for Sikasso. The direction of the vector varies from 15°W of north at 08 h to more than 30°W of north at 17 h for Sao Luiz and from 14°E of north to 25°W of north at 18 h for Sikasso. The plot of the deviations in X and Y at different hours for the two stations shows the points along narrow ellipses with major axis aligned along 22°W of north for Sao Luiz and along 3°W of north for Sikasso as compared to declination of 20°W for Sao Luiz and 6°W for Sikasso. The deviations in X at the two stations are fairly well correlated.

    To investigate the molecular mechanisms underlying the antitumor activity of cepharanthine (CEP),an alkaloid extracted from Stephania cepharantha Hayata.Methods:Human osteosarcoma cell line SaOS2 was used.MTT assay,Hoechst 33342 nuclear staining,flow cytometry,Western blotting and nude mouse xenografts of SaOS2 cells were applied to examine the antitumor activity of CEP in vitro and in vivo.The expression levels of STAT3 and its downstream signaling molecules were measured with Western blotting and immunochemistry analysis.The activity of STAT3 was detected based on the phosphorylation level of STAT3,luciferase gene reporter assay and translocation of STAT3 to the nucleus.Results:Treatment of SaOS2 cells with CEP (2.5-20 μmol/L) inhibited the cell growth in a concentration- and time-dependent manner.CEP (10 μmol/L) caused cell cycle arrest at G1 phase and induced apoptosis of SaOS2 cells.CEP (10 and 15 μmol/L) significantly decreased the expression of STAT3 in SaOS2 cells.Furthermore,CEP (5 and 10 μmol/L) significantly inhibited the expression of target genes of STAT3,including the anti-apoptotic gene Bcl-xL and the cell cycle regulators c-Myc and cyclin D1.In nude mouse xenografts of SaOS2 cells,CEP (20 mg·kg-1-d-1,ip for 19 d) significantly reduced the volume and weight of the tumor.Conclusion:Our findings suggest that inhibition of STAT3 signaling pathway is involved in the anti-tumor activity of CEP.

  11. Green tea polyphenols-induced apoptosis in human osteosarcoma SAOS-2 cells involves a caspase-dependent mechanism with downregulation of nuclear factor-κB

    International Nuclear Information System (INIS)

    Development of chemotherapy resistance and evasion from apoptosis in osteosarcoma, a primary malignant bone tumor, is often correlated with constitutive nuclear factor-κB (NF-κB) activation. Here, we investigated the ability of a polyphenolic fraction of green tea (GTP) that has been shown to have antitumor effects on various malignant cell lines to inhibit growth and induce apoptosis in human osteosarcoma SAOS-2 cells. Treatment of SAOS-2 cells with GTP (20-60 μg/ml) resulted in reduced cell proliferation and induction of apoptosis, which correlated with decreased nuclear DNA binding of NF-κB/p65 and lowering of NF-κB/p65 and p50 levels in the cytoplasm and nucleus. GTP treatment of cells reduced IκB-α phosphorylation but had no effect on its protein expression. Furthermore, GTP treatment resulted in the inhibition of IKK-α and IKK-β, the upstream kinases that phosphorylate IκB-α. The increase in apoptosis in SAOS-2 cells was accompanied with decrease in the protein expression of Bcl-2 and concomitant increase in the levels of Bax. GTP treatment of SAOS-2 cells also resulted in significant activation of caspases as was evident by increased levels of cleaved caspase-3 and caspase-8 in these cells. Treatment of SAOS-2 cells with a specific caspase-3 inhibitor Ac-Asp-Glu-Val-Asp-CHO (Ac-DEVD-CHO) and general caspase inhibitor N-benzyloxycarbonyl-Val-Ala-Asp (OMe)-fluoromethyl ketone (Z-VAD-FMK) rescued SAOS-2 cells from GTP-induced apoptosis. Taken together, these results indicate that GTP is a candidate therapeutic for osteosarcoma that mediates its antiproliferative and apoptotic effects via activation of caspases and inhibition of NF-κB

    Full Text Available Human immunodeficiency virus type 1 (HIV-1 transmitted drug resistance (TDR is an important public health issue. In Brazil, low to intermediate resistance levels have been described. We assessed 225 HIV-1 infected, antiretroviral naïve individuals, from HIV Reference Centers at two major metropolitan areas of Sao Paulo (Sao Paulo and Campinas, the state that concentrates most of the Brazilian Aids cases. TDR was analyzed by Stanford Calibrated Population Resistance criteria (CPR, and mutations were observed in 17 individuals (7.6%, 95% CI: 4.5%–11.9%. Seventy-six percent of genomes (13/17 with TDR carried a nonnucleoside reverse transcriptase inhibitor (NNRTI resistance mutation, mostly K103N/S (9/13, 69%, potentially compromising the preferential first-line therapy suggested by the Brazilian HIV Treatment Guideline that recommends efavirenz-based combinations. Moreover, 6/17 (35% had multiple mutations associated with resistance to one or more classes. HIV-1 B was the prevalent subtype (80%; other subtypes include HIV-1 F and C, mosaics BC, BF, and single cases of subtype A1 and CRF02_AG. The HIV Reference Center of Campinas presented more cases with TDR, with a significant association of TDR with clade B infection (P<0.05.

    This work shows the steps for implementing a program of rational use of electricity in a pine sawmill processing through energy diagnosis and also provide an energy efficiency index, the reference consumption in Kw.h power and volume of timber in cubic meters. The study was conducted in a sawmill located at Itapeva, southwest of Sao Paulo. The region's economic potential is based on the processing of wood with the main export destination. Much of the lumber does not have advanced technology, because it may present with excessive spending power. The species used are Pinus elliottii and Pinus taeda. We collected data on the electrical installation of the mill and the main parts of the installation as tables and distribution lines and equipment engines were studied. The diagnostic results show that while the industry had a good general appearance, electrical installations and equipment using electric power for its functioning need more care, both in maintenance and in use. An energy efficiency program, if effected, could reduce the cost of the process and provides environmental benefits by less need for electric power generation. (author)

    This paper evaluates the total Hg and the trace elements As, Br, Co, Cr and Rb concentrations in muscle of commercially important fishes at the Cubatao, Sao Paulo, Brazil, region. The following carnivore species were analysed: jew fish (Micropogonias furnieri), girl leg (Menticirrhus americanus), hake (Macrodon ancylodon), and plant eaters, sardine (Sardella braziliensis) and grey mullet (Mugil liza), representing a total of 58 samples. The analysed trace elements were determined through the neutron analysis activation (NAA) and total Hg, through the atomic absorption spectrometry with cold vapor generation (CV AAS). The analysed elements present a great concentration variation, not only among individuals of the same specie, but also among all the analysed species. The total Hg concentration were highly significant, with the predator species jew fish, girl leg and hake presenting concentrations larger than the non predator species sardine and grey mullet. Nevertheless, the content of total Hg remained bellow the limits established by the Brazilian legislation which is the 500 {mu}g kg{sup -1} for the non predator species, and the 1000 {mu}g{sup -1} for the predator species (humid weight)

    In the central-northern Ribeira belt there are many granitic to granodioritic bodies showing varied shape and size, characterizing a late- to post-collisional Ca-alkaline, cordilleran I-type province. The Sao Pedro Granite occurs in the mountain region of Rio de Janeiro State as small post-collisional bodies. It presents isotropic fabric, equigranular to seriate inequigranular texture, as well as local concentration of allanite, which gives discrete composition and texture variation to the rock. The granite has a high-K calcalkaline to alkali-calcic character and weakly peraluminous nature. Despite its short geochemical variation, high Ba, Zr and Th contents besides low concentrations of MgO and CaO are noticeable. High REE contents are associated with fractionated REE patterns showing strong negative Eu anomalies. A crustal origin for the granite can be assumed by its very negative and positive .Nd and .Sr values, respectively, as well as by 87Sr/86Sr initial ratios ranging from 0,718 to 0,740. TDM ages point to paleoproterozoic source, which agrees with geological time of intensive crust generation. (author)

    In this study the content of Br, Cl, K, Mg, Mn and V was evaluated in samples of Perna perna mussels collected in coastal regions of Sao Paulo (Ponta de Itaipu and Palmas Island, in Santos) subjected to anthropogenic contamination, to compare these values with those of mussels from reference site of Cocanha Beach (in Caraguatatuba). The mussels were collected seasonally from September 2008 to July 2009. They were cleaned, ground, homogenized, lyophilized and then analyzed by Instrumental Neutron Activation Analysis (INAA). The INAA procedure consisted in the irradiation of the samples and synthetic elemental standards for 8 and 10 s, under a thermal neutron flux of 6.6 x 10{sup 12} n cm{sup -2} s{sup -1} in the IEA-R1 nuclear research reactor. For quality control of analytical results, certified reference materials NIST 1566b Oyster Tissue and NIST 2876 Mussel Tissue were analyzed and their results indicated good accuracy. The ranges of concentrations (dry basis) of the elements obtained in mussels collected for the four seasons of the year were: 173.80 to 358.99 mg kg{sup -1} for Br; 45658 ± 1811 to 109166 ± 824 mg kg{sup -1} for Cl; 7043 ± 856 to 12506 ± 675 mg kg{sup -1} for K; 2774 ± 211 to 5691 ± 717 mg kg{sup -1} for Mg; 7.01 ± 0.30 to 29.74 ± 3.32 mg kg{sup -1} for Mn and 0.77 ± 0.02 to 3.43 ± 0.28 mg kg{sup -1} for V.

    A georeferenced information system energy or simply SIEG, is designed to integrate into the energy matrix of Sao Paulo from 2005 to 2035. Being an innovative request made by the Department of Sanitation and Energy of the state, this system would have the purpose to collect and aggregate information and data from several themes, relating this content in a geographic location spatialized. The main focus of the system is the analysis of the energy sector as a whole, from generation to final consumption, through all phases such as transmission and distribution. The energy data would also be crossed with various themes of support, contributing to the development of numerous reviews and generating sound conclusions. Issues such as environment, socio-economics, infrastructure, interconnected sectors, geographical conditions and other information could be entered, viewed and linked to the system. The SIEG is also a facilitator for planning and managing the energy sector with forecast models in possible future situations. (author)

    Brazil has been on a leading position on fossil fuel substitution in light vehicles. In 2008 and 2009, ethanol contributed with more than 50% of the light vehicle fuel's consumption. A new energetic substitution program was launched in Sao Paulo, and it can be the turning point for the fossil fuel's substitution in the segment of collective transport. This program allows the development of new fuel and engine technologies, and creates opportunities for their deployment on the collective transport market. The economic consequence is a restructuring process that affects the already established markets. There are still big uncertainties about the program's execution, and also about what will be the winning solutions of this, already started, technological race. (author)

    Radiation therapy services provide essential therapeutic procedures for cancer, one of the main causes of population morbidity and mortality. Despite their importance in the health system and their potential risks due to the use of ionizing radiation, there are few studies on such services. We evaluated compliance with technical standards for radiological protection in radiation therapy services in Sao Paulo State, Brazil. Forty-nine services were studied in 2000 through interviews with technical staff. Typologies of performance profiles focusing on structure and process variables were constructed and services compared. Important differences were observed in the services' positions in the health care system, level of complexity, and geographic distribution, with better average performance in structural conditions but very inadequate performance in patient protection, indicating the need for more effective health surveillance.

    One of the major difficult for the planning of co-generation industry of electricity from the sugar cane bagasse is the determination of their true potential. This question comes up, especially in the lack of information about the sugar and ethanol facilities, therefore for the study of potential, we can not just focus on the issue of the cane grinding, but also in technology, the configuration of the power plant and its capacity to export energy. This paper presents a proposal to minimize this difficulty, detailing a solution dedicated to the development of a database for the registration and monitoring of these plants, part of a series of actions regarding in the Understanding Protocol for the promotion of co-generation of bagasse, signed between FIESP and the Government of the State of Sao Paulo.

    The world-wide necessity of greenhouse gases mitigation and the intergovernmental mobilization to reach the objectives established by the United Nations Framework on Climate Change (UNFCCC) has opened space for the renewable energy increase in the world's energy matrix. In Brazil, the solid sugarcane industry currently develops business in the scope of the clean development mechanism (CDM) under the Kyoto's Protocol, by means of 18 biomass-based projects, with renewable energy generation through bagasse cogeneration at 20 Sao Paulo State's sugarcane production units. The projects activity's consists of increasing the efficiency in the bagasse cogeneration facilities, qualifying the units to sell surplus electricity to the national grid, avoiding the dispatch of the same amount of energy produced by fossil-fuelled thermal plants to that grid. The reduced emissions are measured in carbon equivalent and can be converted into negotiable credits. The objective of this study was to build a 'state of art' scenario, calculating the potential emissions reduction through CDM projects for the sugarcane sector of Sao Paulo State, in which we consider the adherence of all the production units of the State to the CDM projects. The technological parameters used to elaborate the scenario were provided by the Sao Paulo State Government Bioenergy Special Commission and the baseline factor used of 0,268 tCO{sub 2}e/MWh was the adopted by the CDM projects in operation in the State. The sugarcane database for the calculations was the production ranking provided by UNICA for the 2006/2007 season. In the most conservative scenario (40 bar bagasse) 131 units could generate 607 MWm of surplus power avoiding the emission of 1.404.593 tCO{sub 2}e/year. For the 92 bar (bagasse and straw) scenario, the units could generate 3.055 MWm of surplus power avoiding 12.199.443 tCO{sub 2}e/year. (author)

    The aims of the present study were to develop boron-incorporated TiO2 coating (B-TiO2 coating) through micro-arc oxidation (MAO) and subsequently evaluate the effect of boron incorporation on the in vitro biological performance of the coatings. The physicochemical properties of B-TiO2 coating and its response to osteoblast like cells (SaOS-2) were investigated compared to the control group without boron (TiO2 coating). The morphological and X-ray diffraction results showed that both coatings exhibited similar surface topography and phase composition, respectively. However, the incorporation of B led to an enhancement in the surface hydrophilicity of B-TiO2 coating. The spreading of SaOS-2 cells on B-TiO2 coating was faster than that on TiO2 coating. The proliferation rate of SaOS-2 cells cultured on B-TiO2 decreased after 5days of culture compared to that on TiO2 coating. SaOS-2 cells cultured on B-TiO2 coating exhibited an enhanced alkaline phosphatase (ALP) activity, Collagen I synthesis and in vitro mineralization compared to those on TiO2 coating. The present findings suggest that B-TiO2 coating is a promising candidate surface for orthopedic implants.

SaOS-2 cells cultured on B-TiO2 coating exhibited an enhanced alkaline phosphatase (ALP) activity, Collagen I synthesis and in vitro mineralization compared to those on TiO2 coating. The present findings suggest that B-TiO2 coating is a promising candidate surface for orthopedic implants. PMID:27287114

    The objective of this study was to assess the infestation level in grapes, Vitis vinifera, by the medfly,Ceratitis capitata in the Sao Francisco River Valley. The adult population was monitored with Jackson trap baited with trimedlure. Samples of grapes for larval infestation assessment were taken along three months, with a total of 116 kg. The average FTD (flies/trap/day) for medfly males was 0.26. The number of pupae obtained from the fruit samples was 471; 287 adults emerged (60.4%), all Ceratitis capitata. The infestation level was 4.0 pupa/kg of fresh fruit. We conclude that grape is a medfly host in SFV, occasionally causing high damage to production. (author)

    Methanol and chloroform extracts were prepared from various parts of four plants collected in Mali: Guiera senegalensis (Gmel.) Combretaceae, Feretia apodanthera (Del.) Rubiaceae, Combretum micranthum (Don.) Combretaceae, Securidaca longepedunculata (Fres.) Polygalaceae and two plants -collected in Sao Tome: Pycnanthus angolensis (Welw.) Myristicaceae and Morinda citrifolia (Benth.) Rubiaceae were assessed for their in vitro antimalarial activity and their cytotoxic effects on human monocytes (THP1 cells) by flow cytometry. The methanol extract of leaves of Feretia apodanthera and the chloroform extract of roots of Guiera senegalensis exhibited a pronounced antimalarial activity. Two alkaloids isolated from the active extract of Guiera senegalensis, harman and tetrahydroharman, showed antimalarial activity (IC(50) lower than 4 microg/mL) and displayed low toxicity against THP1. Moreover, the decrease of THP1 cells in S phase of the cell cycle, after treatment with harman and tetrahydroharman, was probably due to an inhibition of total protein synthesis. PMID:12410545

  14. Potential of municipal solid waste (MSW) as a source of energy in Sao Paulo: its impact on CO2 balance

    International Nuclear Information System (INIS)

    Energy generation is needed in Sao Paulo and MSW represents a promising alternative, although it is more expensive than hydroelectric power. About 14 900 t/day of MSW is generated, of which 8433 t/day is domestic and commercial MSW. From this amount, 1800 t will be destined to generate 30 MW of power. The eco-balance of CO2 has been considered for incineration and recycling. The recycling program of plastics, metals, paper and glass would represent a significant reduction in energy and CO2 emission. The total CO2 released is 3.34 x 105 t/yr without recycling, and is 1.25 x 105 t/yr with a recycling program. Most of the CO2 comes from plastics and paper production. Economic aspects could probably favor incineration with energy production as the best option. (author)

    Although urban horticulture provides multiple benefits to society, the extent to which these vegetables are contaminated by the absorption of chemical elements derived from atmospheric deposition is unclear. This study was designed to evaluate the influence of air pollution on leafy vegetables in community gardens of Sao Paulo, Brazil. Vegetable seedlings of Brassica oleracea var. acephala (collard greens) and Spinacia oleracea (spinach) obtained in a non-polluted rural area and growing in vessels containing standard uncontaminated soil were exposed for three consecutive periods of 30, 60 and 90 days in 10 community gardens in Sao Paulo and in one control site. The concentrations of 17 chemical elements (traffic-related elements and those essential to plant biology) were quantified by Inductively Coupled Plasma Mass Spectrometry (ICP-MS). Tillandsia usneoides L. specimens were used as air plant biomonitors. The concentrations of As, Cd, Cr and Pb found in vegetables were compared to the recommended values for consumption. Principal Component Analysis (PCA) was used to cluster the elemental concentrations, and Generalized Linear Models (GLMs) were employed to evaluate the association of the factor scores from each PCA component with variables such as local weather, traffic burden and vertical barriers adjacent to the gardens. We found significant differences in the elemental concentrations of the vegetables in the different community gardens. These differences were related to the overall traffic burden, vertical obstacles and local weather. The Pb and Cd concentrations in both vegetables exceeded the limit values for consumption after 60 days of exposure. A strong correlation was observed between the concentration of traffic-related elements in vegetables and in Tillandsia usneoides L. An exposure response was observed between traffic burden and traffic-derived particles absorbed in the vegetables. Traffic-derived air pollution directly influences the absorption of

    Full Text Available The accuracy of total ozone computed from the Smithsonian Astrophysical Observatory (SAO optimal estimation (OE ozone profile algorithm (SOE applied to the Ozone Monitoring Instrument (OMI is assessed through comparisons with ground-based Brewer spectrometer measurements from 2005 to 2008. We also make comparisons with the three OMI operational ozone products, derived from the NASA Total Ozone Mapping Spectrometer (TOMS, KNMI Differential Optical Absorption Spectroscopy (DOAS, and KNMI OE (KOE algorithms. Excellent agreement is observed between SAO and Brewer, with a mean difference of less than ±1% at most individual stations. The KNMI OE algorithm systematically overestimates Brewer total ozone by 2% at low/mid latitudes and 5% at high latitudes while the TOMS and DOAS algorithms underestimate it by ~1.65% on average. Standard deviations of ~1.8% are found for both SOE and TOMS, but DOAS and KOE have scatters of 2.2% and 2.6%, respectively. The stability of the SOE algorithm is found to have insignificant dependence on viewing geometry, cloud parameters, total ozone column. In comparison, the KOE differences to Brewer values are significantly correlated with solar and viewing zenith angles, with a significant deviation depending on cloud parameters and total ozone amount. The TOMS algorithm exhibits similar stability to SOE with respect to viewing geometry and total column ozone, but stronger cloud parameter dependence. The dependence of DOAS on the algorithmic variables is marginal compared to KOE, but distinct compared to the SOE and TOMS algorithms. Comparisons of All four OMI products with Brewer show no apparent long-term drift but a seasonally affected feature, especially for KOE and TOMS. The substantial differences in the KOE vs. SOE algorithm performance cannot be sufficiently explained by the use of soft calibration (in SOE and the use of different a priori error covariance matrix, but other algorithm details cause larger fitting

  18. Evaluation of mercury contamination in sediments from Santos - Sao Vicente Estuarine system, in period of 1996 -2000

    International Nuclear Information System (INIS)

    The distribution of mercury contamination in the Santos - Sao Vicente Estuarine System was observed through the analysis of seventy seven surface sediments samples collected in two series. In different periods and points, since the Channel of Piacaguera, the head of the system, , through the estuarine arms of Santos and Sao Vicente as far as the Bay of Santos, about 30 Km downstream, and in different mangrove areas, including industrial and harbor influence zones. The obtained values ranged from 0.03 to 1.19 μg g -1 About 90% of the samples of the first series collected among 1997-1998 and 50% of the second series collected among 1999-2000 presented levels of Hg > 0,13 μg g -1 ,limit considered by the Canadian legislation and adopted by CETESB, below which doesn't happen adverse effect in the biological community. And about 35% of samples of the first series and 11 % of the second series presented concentrations of Hg > 0.698 μg g -1 probable level of occurrence of adverse effect in the biological community. These results indicate an increase of the mercury levels caused by the industrial, port and urban activities. The mercury concentration in sediments was determined by using an Atomic Absorption Spectrophotometer, coupling with a flow injection system by a cold vapor generation, using a manual injection valve (FIA-CVAAS). The estimate of the uncertainties associated to this procedure was calculated. The following elements were also determined: Fe, Al, Zn, Ni, Pb, Cd, Cr and Co in 46 samples of the second series, by atomic absorption spectrometry. In order to verify possible relationship among all the investigated elements in the samples sediments, was carried out a statistical study, using the SPSS-8.0 software. Pearson correlation and Principal Component's analysis were used for with the objective to identify of major relationship for additional exploration of the general behavior of the data. (author)

    International Nuclear Information System (INIS)

    This study presents the development of the methodology of solid phase extraction and liquid chromatography - tandem mass spectrometry, SPE-LC-MS/MS, for the determination of 21 (twenty one) pharmaceuticals belonging to different therapeutic groups, 1 (one) illicit drug and its major metabolite, in surface water samples. The chromatographic separation was optimized by studying the performance of different stationary and mobile phases. Quantitation of selected compounds was performed by electrospray ionization (ESI) and the mass spectrometer operating in a multiple reaction monitoring (MRM) mode. The validation of the proposed methodology was performed using the parameters of selectivity, matrix effect, dynamic range, linearity, limit of detection (LOD), limit of quantification (LOQ), precision, accuracy, recovery and robustness. The validation of methodology allowed to apply the methodology in the evaluation of the distribution of the 23 (twenty one) selected compounds, in Guarapiranga Dam waters, an of the major producer system of drinking water of the Metropolitan Region of Sao Paulo (MRSP). The presence of these pollutants in aquatic environments is from the direct release of urban sewage from the homes of your surroundings, as a result of poor sanitation system. The waters of Guarapiranga dam were evaluated in 14 (fourteen) locations strategically chosen and sampled in 3 (three) campaigns of sample collection (August 2011, September 2012 and April 2013). In these samples were quantified acetaminophen (9.6 - 254 ng L-1), atenolol (8.5 - 177 ng L-1), benzoylecgonine (7.9 - 139 ng L-1), caffeine (27 - 27386 ng L-1) carbamazepine (12 - 358 ng L-1), chlorthalidone (9.4 - 35 ng L-1), cocaine (12.8 - 2560 ng L-1), diclofenac (8 - 36 ng L-1), enalapril (20 ng L-1), losartan (6.7 - 114 ng L-1) and valsartan (9.7 - 47 ng L-1).

    Megacities emissions are increasingly becoming a global issue, where emissions from the transportation sector play an increasingly important role. Sao Paulo is a megacity with a population of about 18 million people, 7 million cars and large-scale industrial emissions. As a result of the vehicular and industrial emissions, the air quality in Sao Paulo is bellow WMO standards for aerosol particles and ozone. Many uncertainties are found on gas- and particulate matter vehicular emission factors and their following atmospheric processes, e.g. secondary organic aerosol formation. Due to the uniqueness of the vehicular fuel in Brazil, largely based on ethanol use, such characterization currently holds further uncertainties. To improve the understanding of the role of this unique emission characteristics, we are running a source apportionment study in Sao Paulo focused on the mechanisms of organic aerosol formation. One of the goals of this study is a quantitative aerosol source apportionment focused on vehicular emissions, including ethanol and gasohol (both fuels used by light-duty vehicles). This study comprises four sampling sites with continuous measurements for one year, where trace elements and organic aerosol are being measured for PM2.5 and PM10 along with real-time NOx, O3, PM10 and CO measurements. Aerosol optical properties and size distribution are being measured on a rotation basis between sampling stations. Furthermore, a Proton-Transfer-Reaction Mass Spectrometer (PTR-MS) and an Aerosol Chemical Speciation Monitor (ACSM) are used to measure in real time VOCs and aerosol composition, respectively. Trace elements were measured using XRF and OC/EC analysis was determined with a Sunset OC/EC instrument. A TSI Nephelometer with 3 wavelengths measure light scattering and a MAAP measure black carbon. Results show aerosol number concentrations ranging between 10,000 and 35,000 cm-3, mostly concentrated in the nucleation and Aitken modes, with a peak in size at 80

  5. Determination of total and organic mercury and evaluation of methylation and demethylation processes in sediments of the Rio Grande Reservoir, State of Sao Paulo, Brazil

    International Nuclear Information System (INIS)

    The Rio Grande reservoir is located in the metropolitan area of Sao Paulo and it is a very important water supply for this region. In the present study bottom waters and sediment samples collected in this reservoir, in four sampling points, in four campaigns, from September 2008 to January 2010, were analyzed. Firstly total Hg was determined in sediment and bottom waters by cold vapor atomic absorption technique (CV AAS). Following, the analytical methodology for organic Hg was adapted from literature, where the organomercurial compounds were extracted with dichloromethane in acid medium and subsequent destruction of organic compounds by bromine chloride. The validation of this methodology, in terms of precision and accuracy, was performed by means of IAEA 405 and BCR-CRM 580 reference materials analyses. For methylation and demethylation processes evaluation in this environment, the following physical and chemical parameters were assessed, in situ: pH, water temperature, redox potential (EH), transparency and depth. For the sediment samples, granulometry, total organic carbon, sulphate-reducing bacteria, total N and P, besides the metals Co, Cu, Fe and Mn were evaluated. The selection of these parameters was related to the factors that influence the behavior of MeHg in the sediments and its transition zone. Total Hg ranging from 1.0 to 71.0 mg kg'-1 and organic mercury from -1 in sediments and methylation rates from 0.06 to 1.4% were found, along the reservoir. Different methylation conditions along the reservoir and its influences were also discussed. As supplementary study the concentration of some metals and trace elements in the sediments by neutron activation analysis technique was determined. As, Ba, Br, Co, Cr, Cs, Hf, Fe, Na, Rb, Sb, Sc and Zn and rare earth elements Ce, Eu, La, Lu, Nd, Sm and Yb were determined. The enrichment factor in relation to earth crust values using Sc as normalizer element reached values higher than 2.0 for the elements As, Br, Sb

    To estimate the potential for energy saving in cold compressor motor of a food industry, a study was conducted in a slaughterhouse in the state of Sao Paulo. It was analyzed only the engine room of the company because according to measurements this one corresponds approximately 97% of all electricity consumption of the unit. It was found that the electrical efficiency indices were low, demonstrating the possibilities for adoption of conservation measures and the rationalization of electric energy. It was evident that the establishment of an efficiency study to change the electrical equipment used was feasible and, therefore, was demonstrated and proposed a new arrangement for the current system. Soon after the diagnosis of the use of electricity was found that from the six Machinery, five were oversized. Then it was suggested to replace these machines by others with lower power and greater efficiency, as well as conducted an analysis of technical and economic feasibility of the project, demonstrating the possibilities for the rational use of energy and the optimization of financial resources company (author)

    This work applies the sequence stratigraphy concepts in the faciological analysis based on the individualization of the boundary surfaces and the architectural elements, with the aim to work out prediction models for the permeability changes of the oil reservoir from fluvial-deltaic Sao Sebastiao Formation, Reconcavo Basin. The descriptions of drill holes and outcrops related to the studied interval allow to recognize three complete 4th order sequences, all of that limited by erosive surfaces. The best oil reservoirs are related to fluvial sandstones deposited during the low stand system tract and to deltaic sandstones from the lower portion of the transgressive system tract. The main sealers of the oil reservoir are the maximum flooding surfaces. The fluvial oil reservoirs are homogeneous, however the deltaic ones have a good lateral continuity, but a lower vertical connectivity in the sand bodies. The vertical and lateral inter finger of the D A and S B elements control the flow units in fluvial systems. In deltaic systems, the reservoir homogeneity depends on the relation between deltaic front and pro delta deposits. (author)

    Utilization of the biogas proceeding from urban solid residues for electricity generation: case study in Sao Paulo. The biogas, generated from organic matter degradation, is composed by a mixture of gases, the main components being carbon dioxide and methane, which is a greenhouse effect gas with global warming potential around 21 times greater when compared to CO{sub 2}. Biogas production is possible from a great variety of organic residues such as urban solid residues, residues from agricultural and livestock activities, swine livestock, sewage mud, among others. The sanitary landfills may count on techniques of capture of the produced biogas and its later burning in flare, where the methane is transformed in CO{sub 2}, minimizing the environmental impact. Besides the opportunity of reducing the environmental damages, biogas can also be used as fuel for generating electricity, thus adding environmental gain and reduction of costs, due to the diminishing of purchase of the energy consumed in the concessionaire. In this context, this article presents the project of utilization of biogas proceeding from urban solid residues for electricity generation and gas illumination, developed by CENBIO. This project is currently in development and the obtained results will provide technical and economic subsidies for its replication. (author)

    Recent foraminifera assemblages were studied to determine an ecological model of species distribution, diversity, equability and confining degree, with implications to environmental diagnosis and paleoenvironmental reconstructions. The study area is inserted in a sector from Sao Francisco River delta, with interconnected channels and a lagoon connected to the ocean. Besides the biotic variables, sediment salinity and granulometry was considered. An agglomerative hierarchical clustering (AHC) was performed and it was recognized three bio facies distributed along the sector: Miliammina/Arenoparrella in the channels, and Ammonia/Elphidium and Quinqueloculina at the lagoon. The diversity and equability values increase from the Miliammina/Arenoparrella biofacies to the Ammonia/Elphidium and Quinqueloculina biofacies. The confining indices show environments ranging from confined (channels) to different degrees of low restricted to marine influence. From the results obtained, it is possible to recognize that environments dominated by textulariines are characterized by low diversity, equability and high confining degree. Environments dominated by rotaliines and miliolines tend to be more diversified, equitable and low restricted to marine influence. The results are similar to other obtained in other Brazilian estuarine environments, differing only on dominance by some species (author)

  14. Total Diet Study. Mg and Mn content estimation of a Market Basket of Sao Paulo state (Brazil) by Instrumental Neutron Activation

    International Nuclear Information System (INIS)

    Total Diet Studies (TDS) have been carried out to estimate dietary intakes of the essential and toxic elements for a large-scale population over a specific period of time. In this study, the TDS was based on the evaluation of food representing a Market Basket (MB), which reflected the dietary habits of the Sao Paulo State population, corresponding to 72 % of the average food consumption for the state of Sao Paulo. In the present Total Diet Study, magnesium and manganese concentrations were determined in 30 of the most consumed food groups of a MB of Sao Paulo State, Brazil. Instrumental Neutron Activation Analysis (INAA) has been successfully used on a regularly basis in several areas of nutrition and foodstuffs. Element concentrations were determined by INAA in freeze-dried samples and ranged in mg kg-1. Mg 41.4 (fats)-5287 (coffee) and Mn 0.12 (prime grade beef)-32.9 (coffee). The average daily Mg and Mn intake was calculated by multiplying the concentration of each element in each table-ready food group by the respective weight (g day-1) of the food group in the MB and adding the products from all food groups. The results of daily dietary intakes in this study were: Mg 174.8 and Mn 1.34 mg day-1. Theses values were lower than the adequate intake (AI) proposed by the Food and Nutrition Board of the Institute of Medicine (USA National Academy) for adults. The low levels of Mg and Mn intakes presented in this TDS are probably due to the fact that MB of this study represented only 72 % of the weight of the most consumed household foods of Sao Paulo State.

    Objectives To (a) assess the association between dietary diversity (DD) score, socioeconomic status (SES) and maternal body mass index (BMI), and (b) the variation of the effects of DD and SES at different points of the conditional distribution of the BMI. Methods The study used Demographic and Health Surveys round 5 data sets from Ghana, Namibia and Sao Tome and Principe. The outcome variable for the analysis was maternal BMI. The DD score was computed using 24-hour dietary recall data. Quantile regression (QR) was used to examine the relationship between DD and SES, and maternal BMI, adjusting for other covariates. The QR allows the covariate effects to vary across the entire distribution of maternal BMI. Results Women who consumed an additional unit of DD achieved an increase of 0.245 in BMI for those in the 90th quantile in Ghana. The effect of household wealth increases for individuals across all quantiles of the BMI distribution and in all the 3 countries. A unit change in the household wealth score was associated with an increase of 0.038, 0.052 and 0.065 units increase in BMI for individuals in the 5th quantile in Ghana, Namibia and Sao Tome and Principe, respectively. Also, 0.237, 0.301 and 0.174 units increased for those in the 90th quantile in Ghana, Namibia and Sao Tome and Principe, respectively. Education had a significant positive effect on maternal BMI across all quantiles in Namibia and negative effect at the 5th, 10th and 90th quantiles in Sao Tome and Principe. Conclusions There is heterogeneity in the effects of DD and SES on maternal BMI. Studies focusing on the effects of diet and socioeconomic determinants on maternal BMI should examine patterns of effects at different points of the conditional distribution of the BMI and not just the average effect.

    Polymeric silica is formed from ortho-silicate during a sol-gel formation process, while biosilica is the product of an enzymatically driven bio-polycondensation reaction. Both polymers have recently been described as a template that induces an increased expression of the genes encoding bone morphogenetic protein 2 (BMP-2) and osteoprotegerin in osteoblast-related SaOS-2 cells; simultaneously or subsequently the cells respond with enhanced hydroxyapatite formation. In order to assess whether the biocompatible polymeric silica/biosilica can serve as a morphogenetically active matrix suitable for three-dimensional (3D) cell growth, or even for 3D cell bioprinting, SaOS-2 cells were embedded into a Na-alginate-based hydrogel. Four different gelatinous hydrogel matrices were used for suspending SaOS-2 cells: (a) the hydrogel alone; (b) the hydrogel with 400 μM ortho-silicate; (c) the hydrogel supplemented with 400 μM ortho-silicate and recombinant silicatein to allow biosilica synthesis to occur; and (d) the hydrogel with ortho-silicate and BSA. The SaOS-2 cells showed an increased growth if silica/biosilica components were present in the hydrogel. Likewise intensified was the formation of hydroxyapatite nodules in the silica-containing hydrogels. After an incubation period of 2 weeks, cells present in silica-containing hydrogels showed a significantly higher expression of the genes encoding the cytokine BMP-2, the major fibrillar structural protein collagen 1 and likewise of carbonic anhydrase. It is concluded that silica, and to a larger extent biosilica, retains its morphogenetic/osteogenic potential after addition to Na-alginate-based hydrogels. This property might qualify silica hydrogels to be also used as a matrix for 3D cell printing.

    The coastal environment has been heavily altered by multiple environmental impacts of human activities, such as disposal of sewage from urban areas, the release of numerous chemical industries, agriculture and the flow of vessels, which can lead to accidental spills of oil and oil products, fuels and other products transported by sea. In this context, a means of determining concentrations of these potentially toxic substances in the sea water is the biomonitoring by means of different types of bivalves, which have been used by various researchers, in Brazil and other countries. With regard to bivalve mollusks, particularly mussels, their use in monitoring the marine contamination is mainly due to their wide geographic distribution, sessile habit and ability to concentrate toxic metals to 102-105 times in relation to the concentrations detected in water. In the present study, we employed the passive biomonitoring using the Perna perna bivalve mollusk with respect to the elements Br, Cl, K, Mg, Mn and V. These elements were chosen since they can be determined by INAA method (Instrumental Neutron Activation Analysis), by means of short irradiation which provides faster analyzes and also due to their importance from the standpoint of environmental or nutritional studies. The aim of this study was to evaluate the content of Br, Cl, K, Mg, Mn and V in samples of Perna perna mussels (Linnaeus, 1758: Mollusca, Bivalvia) collected in coastal regions of Sao Paulo subject to anthropogenic contamination (Ponta de Itaipu and Palmas Island, in Santos), comparing the values obtained in sites potentially impacted with the values of the control site in Praia da Cocanha, in Caraguatatuba. The collection points located in Sao Paulo coast are located in the geographical areas 23 Masculine-Ordinal-Indicator 37'S - 45 Degree-Sign 24' W (Caraguatatuba) and 23 Masculine-Ordinal-Indicator 57'S - 46 Masculine-Ordinal-Indicator 20' W (Santos).

    The determination of trace elements plays an important role in the characterization of archaeological ceramics. It is well established that ceramics can be grouped based on similarities/dissimilarities derived from chemical data. Different analytical methods can be applied to determine the sample composition. Instrumental neutron activation analysis (INAA) is the method preferred because present several advantages in relation to the other techniques. In this work, the elements determined were As, K, La, Lu, Na, Nd, Sb, Sm, U, Yb, Ba, Ce, Co, Cr, Cs, I, Fe, Hf, Rb, Sc, Ta , Tb, Th and Zn to carry out a preliminary chemical characterization in 44 ceramic samples from Sao Paulo II archaeological site by INAA. The site is located in Coari city, 363 km from Manaus, Amazonas state (AM). The elementary concentration results were studied using multivariate statistical methods. The similarity/dissimilarity among the samples was studied by means of discriminant analysis. The compositions group classification was done through cluster analysis, showing the formation of the three distinct groups of the ceramics. (author)

    The occurrence of flight delays in Brazil, mostly verified at the ground (airfield), is responsible for serious disruptions at the airport level but also for the unchaining of problems in all the airport system, affecting also the airspace. The present study develops an analysis of delay and travel times at Sao Paulo International Airport/ Guarulhos (AISP/GRU) airfield based on simulation model. Different airport physical and operational scenarios had been analyzed by means of simulation. SIMMOD Plus 4.0, the computational tool developed to represent aircraft operation in the airspace and airside of airports, was used to perform these analysis. The study was mainly focused on aircraft operations on ground, at the airport runway, taxi-lanes and aprons. The visualization of the operations with increasing demand facilitated the analyses. The results generated in this work certify the viability of the methodology, they also indicated the solutions capable to solve the delay problem by travel time analysis, thus diminishing the costs for users mainly airport authority. It also indicated alternatives for airport operations, assisting the decision-making process and in the appropriate timing of the proposed changes in the existing infrastructure.

    A comprehensive estimation of polyphenol intake is needed to gain a better understanding of the association between polyphenol-rich food intake and the potential effects of this intake on chronic diseases. The aim of this study was to estimate the intake of polyphenols and the major dietary contributors in the population of Sao Paulo. Data were obtained from the Health Survey-São Paulo (ISA-Capital 2008) and were reported for 1103 adults and elderly adults. Food intake was estimated by one 24-h dietary recall (24HR). Polyphenol intake was calculated by matching food consumption data from the 24HR with the polyphenol content in foods listed in the Phenol-Explorer database. The mean total intake of polyphenols was 377·5 (se 15·3) mg/d. The main polyphenol classes were phenolic acids (284·8 (se 15·9) mg/d) and flavonoids (54·6 (se 3·5) mg/d). Intakes were higher in the elderly adults than in other adults (Pcitrus fruits (4·6 %) and tropical fruits (3·4 %). Coffee was the major source of polyphenols, providing 266·2 (se 16·5) mg/d, and contributed 92·3 % of the phenolic acids and 93·1 % of the alkylmethoxyphenols. These findings will be useful for assessing the potential role on health of polyphenols and specific polyphenol-rich foods, such as coffee, and enable a comparison with people from other countries.

    The health of astronauts, during space flight, is threatened by bone loss induced by microgravity, mainly attributed to an imbalance in the bone remodeling process. In the present work, the response to the microgravity of bone cells has been studied using the SAOS-2 cell line grown under the condition of weightlessness, simulated by means of a Random Positioning Machine (RPM). Cell viability after 72 h of rotation has been evaluated by means of WST-8 assay and compared to that of control cells. Although no significant difference between the two cell groups has been observed in terms of viability, F-actin staining showed that microgravity environment induces cell apoptosis and altered F-actin organization. To investigate the possibility of hindering the trend of the cells towards the death, after 72 h of rotation the cells have been seeded onto biocompatible ZrO2/PCL hybrid coatings, previously obtained using a sol-gel dip coating procedure. WST-8 assay, carried out after 24 h, showed that the materials are able to inhibit the pro-apoptotic effect of microgravity on cells.

    Ca-phosphate/hydroxyapatite (HA) crystals constitute the mineral matrix of vertebrate bones, while Ca-carbonate is the predominant mineral of many invertebrates, like mollusks. Recent results suggest that CaCO₃ is also synthesized during early bone formation. We demonstrate that carbonic anhydrase-driven CaCO₃ formation in vitro is activated by organic extracts from the demosponge Suberites domuncula as well as by quinolinic acid, one component isolated from these extracts. Further results revealed that the stimulatory effect of bicarbonate (HCO₃ (-)) ions on mineralization of osteoblast-like SaOS-2 cells is strongly enhanced if the cells are exposed to inorganic polyphosphate (polyP), a linear polymer of phosphate linked by energy-rich phosphodiester bonds. The effect of polyP, administered as polyP (Ca²⁺ salt), on HA formation was found to be amplified by addition of the carbonic anhydrase-activating sponge extract or quinolinic acid. Our results support the assumption that CaCO₃ deposits, acting as bio-seeds for Ca-carbonated phosphate formation, are formed as an intermediate during HA mineralization and that the carbonic anhydrase-mediated formation of those deposits is under a positive-negative feedback control by bone alkaline phosphatase-dependent polyP metabolism, offering new targets for therapy of bone diseases/defects.

    Dengue fever has become a worldwide public health concern, threatening an estimated 40% of the world's population. However, most resources and attention are still focused on malaria, while dengue statuses are poorly recognized in many African countries. In this serological survey, dengue virus (DENV) transmission was demonstrated by using serum samples collected from 78 pregnant women in the Democratic Republic of Sao Tome and Principe (DRSTP) during 2003 to 2004. Immunofluorescence assay was performed and 31 samples (39.74%) were found positive for DENV antibodies. Indirect enzyme-linked immunosorbent assay (ELISA) showed that 53 samples (67.95%) were positive for dengue E IgG, and 38 samples (48.72%) were positive for NS1 IgG. A prevalence of 35.90% was therefore determined for dengue IgG by considering samples that yielded positive results by all three tests. Cross-reactions with other flaviviruses were examined by indirect ELISA against Japanese encephalitis virus, West Nile virus, and yellow fever virus. Only one sample exhibited stronger absorbance against Japanese encephalitis virus and West Nile virus. Moreover, one sample was positive for dengue IgM. These results agreed with the previous researches in neighboring countries and suggested DENV exposure. The study contributes to raising public awareness of dengue and supporting future control strategies.

    The study of rare earth elements (REE) distribution in urban environments has become very interesting in the last years, due to the increasing industrial use of these elements. The REE La, Ce and Nd are used in automobile converter catalysts to stabilize the catalyst support and to enhance the oxidation of pollutants. The honeycomb structure has a typical association of a high Ce (and often also La) concentration combined with high concentrations of Platinum Group Elements. Due to thermal and mechanical wear of catalysts, fine particles enriched in REE are released to the environment. These catalyst particles can accumulate in urban soils, mainly in soils located near high density traffic roads. The aim of this paper was to study the REE distribution and ratios in surface soil samples collected in fourteen urban public parks of Sao Paulo city, to assess the influence of vehicular emissions. Instrumental Neutron Activation Analysis (INAA) was used for the REE analysis. The diagrams normalized to chondrite values showed an enrichment of the light REE (La to Sm), in contrast to the heavy REE (Eu to Lu), with a negative anomaly of Eu. The results obtained indicated that the enrichment in REE is not clearly attributed to vehicular traffic, because of high background values associated to the natural geological composition of the soils.

    Full Text Available Rabies is a viral disease that can affect all mammals and is transmitted primarily by the saliva of infected vampire bats. It is important that animals are immunized with rabies vaccine, although this is not mandatory in farmed animals. This study aimed to assess the frequency of rabies vaccination in animals from farms in Botucatu, SP, Brazil. Farmers were interviewed from a questionnaire. Sixty-five percent of the 224 visited farms sighted bats and 27% reported attacks over the herd. Fifty percent of owners inoculated animals while another 45% and 5% did not inoculate or did not answer the questionnaire, respectively. It was observed that in cities with fewer attacks, the animals were immunized. In 112 properties, 10,148 animals were vaccinated (mean = 91 animals / property, particularly those of intensive farming. Most did not justify why they did not vaccinate their animals. It was concluded that despite the presence of bats in the region and the occurrence of attacks on animals there is little concern and prevention of rabies. Lack of guidance and / or information on the subject can be one of the main reasons for non-vaccination of horses and cattle in Botucatu region. Thus, it is emphasized the importance of professional performance in Agribusiness, in guiding farmers on the necessary preventive measures to ensure success in herd through health and animal welfare.

In order to analyze the water quality of these dams, this paper presents a diagnostic physical, chemical, and biological, which was used in the phytoplankton community and calculation of quality indexes. Four samples were taken at nine sampling points distributed along the dams. The physical and chemical analysis of water showed low concentrations of nutrients such as nitrate (mean 0,42 {+-} 0,23 mg.L{sup -1} and phosphate (<0,05 mg.L{sup -1}). Most metals and trace elements analyzed were within the limit established by federal law. The element phosphorus (mean 0,0293 {+-} 0,0153 mg.L{sup -1}) is presented above the values established by CONAMA Resolution 357/05 (0,020 mg.L{sup -1}) on all sampling points in the month of May, but this fact did not seem to influence the phytoplankton amount. High levels of dissolved oxygen and transparency, low levels of turbidity, conductivity and dissolved solids, pH close to neutrality, together with high diversity and low dominance of phytoplankton, with a predominance of green algae, showed that the dams still retain features of aquatic environment preserved, which suffer little influence of anthropogenic factors. However, the presence, even at low densities, of cyanobacteria and the existence of plantations and livestock activities in the borders of these dams deserve special attention in terms of their correct management to not become harmful factors to the quality of those waters.

    This study presents the development of the methodology of solid phase extraction and liquid chromatography - tandem mass spectrometry, SPE-LC-MS/MS, for the determination of 21 (twenty one) pharmaceuticals belonging to different therapeutic groups, 1 (one) illicit drug and its major metabolite, in surface water samples. The chromatographic separation was optimized by studying the performance of different stationary and mobile phases. Quantitation of selected compounds was performed by electrospray ionization (ESI) and the mass spectrometer operating in a multiple reaction monitoring (MRM) mode. The validation of the proposed methodology was performed using the parameters of selectivity, matrix effect, dynamic range, linearity, limit of detection (LOD), limit of quantification (LOQ), precision, accuracy, recovery and robustness. The validation of methodology allowed to apply the methodology in the evaluation of the distribution of the 23 (twenty one) selected compounds, in Guarapiranga Dam waters, an of the major producer system of drinking water of the Metropolitan Region of Sao Paulo (MRSP). The presence of these pollutants in aquatic environments is from the direct release of urban sewage from the homes of your surroundings, as a result of poor sanitation system. The waters of Guarapiranga dam were evaluated in 14 (fourteen) locations strategically chosen and sampled in 3 (three) campaigns of sample collection (August 2011, September 2012 and April 2013). In these samples were quantified acetaminophen (9.6 - 254 ng L{sup -1}), atenolol (8.5 - 177 ng L{sup -1}), benzoylecgonine (7.9 - 139 ng L{sup -1}), caffeine (27 - 27386 ng L{sup -1}) carbamazepine (12 - 358 ng L{sup -1}), chlorthalidone (9.4 - 35 ng L{sup -1}), cocaine (12.8 - 2560 ng L{sup -1}), diclofenac (8 - 36 ng L{sup -1}), enalapril (20 ng L{sup -1}), losartan (6.7 - 114 ng L{sup -1}) and valsartan (9.7 - 47 ng L{sup -1}).

  18. Determination of natural Ra isotopes in samples from northern Sao Paulo state coastal area

    International Nuclear Information System (INIS)

    The present work aims the determination of natural Ra isotopes in coastal samples collected at Ubatuba region, with the application of the obtained inventories to estimate coastal water mixing rates and assess submarine groundwater discharge. Since these radionuclides are present in sea water in trace form (10''-16 g/ L), the methodology included pre-concentration of huge volumes of sea water using MnO2 coated acrylic fiber, leaching of these fibers in HCl media and co-precipitation of the long-lived Ra isotopes with BaSO4. Before long-lived radium isotopes determination, the isotopes 223Ra e 224Ra were quantified using a delayed coincidence system. The delayed coincidence system utilizes the difference in decay constants of the short-lived Po daughters of radon 219Rn and 220Rn to identify alpha particles derived from its decay products. The activities of 226Ra and 228Ra were determined by gross alpha and beta counting respectively, of the Ba(Ra)SO4 precipitate in low-level gas flow proportional detector. Considering the results obtained in 2002 and 2003, the coastal waters exchange time were estimated for Flamengo, Fortaleza and Mar Virado embayments using the activity concentrations of 223Ra, 224Ra, 226Ra and 228Ra.

  19. Assessment of natural radium isotopes and 222Rn in water samples from Cananeia-Iguape estuarine complex, Sao Paulo, Brazil

    International Nuclear Information System (INIS)

    Radium isotopes and radon are among the most important natural radionuclides in the environment from both radioprotection and geo-hydrological points of view. These radionuclides are a powerful tool for studying coastal processes and have been used intensively as tracers of groundwater sources that discharge into the ocean. In this paper, naturally occurring radium isotopes and 222Rn were determined to trace water exchange and SGD in Cananeia-Iguape estuarine complex, a shallow coastal plain estuary in southern Sao Paulo area. The research work was carried out during the first semester of 2009 and covered stations located both in Cananeia and Iguape outlets, as well as samples collected in Ribeira of Iguape River and groundwater. Activity concentrations of 226Ra in estuarine waters from Cananeia outlet varied from 2.9 mBq L-1 to 4.7 mBq L-1, while 228Ra concentrations ranged from 22 mBq L-1 to 45 mBq L-1. In Iguape outlet, activities of 226Ra ranged from 1.6 mBq L-1 to 6.6 mBq L-1; 228Ra varied from 13 mBq L-1 to 20 mBq L-1. Activities of Ra were slightly higher in samples collected at 5 m depth than at the surface water level. Groundwater activity concentrations of 226Ra ranged from 0.63 mBq L-1 to 12 mBq L-1 and for 228Ra from 18 mBq L-1 to 39 mBq L-1. In groundwater, the 228Ra/226Ra activity ratios varied from 3.3 to 31.7. 222Rn activities in groundwater up to 747 Bq L-1 were observed. Increased nitrate contents were observed in groundwater samples collected in Cananeia and Comprida Island. (author)

    A comprehensive estimation of polyphenol intake is needed to gain a better understanding of the association between polyphenol-rich food intake and the potential effects of this intake on chronic diseases. The aim of this study was to estimate the intake of polyphenols and the major dietary contributors in the population of Sao Paulo. Data were obtained from the Health Survey-São Paulo (ISA-Capital 2008) and were reported for 1103 adults and elderly adults. Food intake was estimated by one 24-h dietary recall (24HR). Polyphenol intake was calculated by matching food consumption data from the 24HR with the polyphenol content in foods listed in the Phenol-Explorer database. The mean total intake of polyphenols was 377·5 (se 15·3) mg/d. The main polyphenol classes were phenolic acids (284·8 (se 15·9) mg/d) and flavonoids (54·6 (se 3·5) mg/d). Intakes were higher in the elderly adults than in other adults (Ppolyphenols were coffee (70·5 %), citrus fruits (4·6 %) and tropical fruits (3·4 %). Coffee was the major source of polyphenols, providing 266·2 (se 16·5) mg/d, and contributed 92·3 % of the phenolic acids and 93·1 % of the alkylmethoxyphenols. These findings will be useful for assessing the potential role on health of polyphenols and specific polyphenol-rich foods, such as coffee, and enable a comparison with people from other countries.

    Full Text Available Drug use and the challenge of finding answers in assistance to the so called drug abuse is a current theme that challenges professionals, services and managers. This study aimed to map features, professionals and the activities carried out by occupational therapists of the Psychosocial Care Centers of Alcohol and other Drugs (Centros de Atenção Psicossocial Álcool e Drogas – CAPS ad in the state of Sao Paulo, through the application of a self-answerable questionnaire. During data collection, 45 CAPS ad were found in the interior of the state. Nineteen professionals cooperated with the research; 15 of them were occupational therapists. The results showed that these care centers present proposals regulated according to the guidelines of the Ministry of Health, but the complexity of the demand and its multiple facets with the social dimension require further discussion on the type of intervention that has been employed, as well as on its efficacy. Regarding the profile of the occupational therapists, most of them have at least five years of training, graduate degrees, and did not choose the area of mental health and drugs. The occupational therapists have different views of their actions, use different resources and strategies, especially in group activities and through workshops, and signify their actions in different ways, promoting new projects of life by joining treatment proposals from abstinence to harm reduction. We conclude that the assistance to the users of CAPS ad is extremely complex, because it involves social character themes with macro social determinants which require greater integration between sectors, areas and resources.

  2. Study of socio environmental actions of Energy and Nuclear Research Institute of Sao Paulo (IPEN/CNEN-SP)

    International Nuclear Information System (INIS)

    Over the years the evolution of environmental concept comes solidifying increasingly through programs, conferences and various activities taking place in Brazil and worldwide. As a result of this development, sustainability and social responsibility began to be seen as something present in day to day business and institutions. In particular, the Institute of Energy and Nuclear Research (IPEN), state authority associated with University of Sao Paulo (USP) and managed by the National Commission of Nuclear Energy (CNEN), subordinate the Ministry of Science and Technology, which is the focus of this work, has the mission the commitment to society as regards: improving the quality of life of the population, producing scientific knowledge, developing technologies, generating products and services and training human resources in nuclear and related. Based on the mission of IPEN and in the lack of assessment tools of social actions, this paper aims to propose an instrument for assessing social responsibility and serve as a methodological option, strongly committed to the pursuit of improvements of IPEN. Through indicators and dimensions, built up a methodology that seeks to assess social responsibility and identify strengths, to be encouraged and weaknesses, which can be studied and improved. This methodology was applied to IPEN and the results that are presented in this work identified positives regarding their actions to their domestic audience and points to be improved in relation to their external audience. As an initial evaluation, the results were satisfactory; however, this work will continue in order to suggest the implementation of social and environmental actions feasible to be applied in IPEN.

    Full Text Available OBJECTIVE: The objective of this study was to identify possible barriers to control vertical transmission of syphilis and HIV through the analysis of the orientation process of pregnant women from prenatal care to the obstetric center at an university hospital in Sao Paulo (Reference and their return (with their exposed babies for follow-up after hospital discharge (counter-reference. METHODS: It is a retrospective cross-sectional study including interviews with healthcare personnel. Pregnant women with syphilis and/or HIV-infection admitted for labor or miscarriage were identified from August 2006 to August 2007. Routine care for mothers and babies were analyzed. RESULTS: 56 pregnant women were identified: 43 were HIV-infected, 11 had syphilis and two were coinfected (syphilis/HIV; 22 health care professionals were interviewed. Prenatal care was identified in 91.1% of these women: 7/11 (63.6% with syphilis; 44/45 (97.8% HIV-infected or coinfected. The reference for delivery was satisfactory for 57.7% of the syphilis-infected women and 97.7% of the HIV-infected ones. The counter-reference was satisfactory for all babies and mothers at hospital discharge, besides the non-adherence to this recommendation. Interviews with health care professionals showed there are better routines for assisting and following-up pregnant women, puerperal women and HIV-infected or exposed babies than for those infected with syphilis. The epidemiological report and surveillance system are also better for HIV-infected patients. CONCLUSION: The difficulties in the reference and counter-reference system of these women and their babies are evident barriers to control the vertical transmission of these infectious diseases.

  4. Lichen specie Canoparmelia texana as bioindicator of environmental impact from the phosphate fertilizer industry of Sao Paulo, Brazil

    International Nuclear Information System (INIS)

    The Brazilian phosphate industry is the sixth worldwide producer of phosphate rock concentrate generating phosphoric acid, fertilizers, intermediates for fertilizers and other products. Two of the most important of these industries are both located in the city of Cubatao-Sao Paulo, Brazil, and they are responsible for the production of P2O5, generating a residue known as phosphogypsum. The raw material, phosphate rock and products are commonly transported to the industrial complex by a railroad line and present in their composition natural radionuclides from the U and Th series and rare earth elements. Lichens have been used for monitoring atmospheric pollution and radiological contamination for a long time and have proven to be an important tool. This paper aims to highlight the use of the lichen specie Canoparmelia texana (family Parmeliacea) as a bioindicator of atmospheric pollution by the natural radionuclides from the U and Th series and RREs due to the operation of these industries and the storage of their residue in the open air. Samples of these lichen specie were collected in the vicinity of the industries and the railroad. The radionuclides 226Ra, 228Ra and 210Pb were measured by alpha and beta counting, after radiochemical separation, and 238U, 232Th as well as REEs were determined by instrumental neutron activation analysis. The results showed that the lichens present the same fingerprint as the phosphate rock and phosphogypsum, furthermore the cluster analysis of the results showed that the lichen samples collected near to the railroad line presented the highest values for all the elements studied.

    The earth's crust has in its composition the Naturally Occurring Radioactive Material (NORM) that may have increased concentration due to activities of exploration and extraction of environmental resources. The civil construction is an economic activity that requires the use of much of the natural resources, such as the raw material of brick works, like clays, mainly used for the production of bricks and tiles. These construction materials may contain high levels of natural radioactive elements, even with concentrations higher than the limits established, given that the levels vary according to the composition of rocks and soil, due to the geological formation and may result in increased exposure of humans to natural radioactive activities. In this context, the radioecological dosimetry is defined in terms of Radium Equivalent activity (Ra{sub eq}), that ensure radiometric conditions for the use of material derived from clays before its final application in housing construction, an initiative that ensures the radioecological safety of population. Thus, this study aimed to establish the calculation of Ra{sub eq} in the raw material of brick works located in Sao Jose do Sabugi city, state of Paraiba, in an area adjacent to the uranium deposits of Espinharas, to estimate the risks associated with primordial radionuclides attributed to TENORM activities (Technologically Enhanced Naturally Occurring Radioactive Materials) from the extraction and use of clay as a raw material in the manufacture of bricks and tiles. Analyses were performed by High Resolution Gamma Spectrometry, with HPGe-Be detector, assuming the state of secular radioactive equilibrium. The results ranged from 183.2 to 747.78 Bq/kg, with an average of 494.6 Bq/kg which exceeded the limit of 370 Bq/kg established by UNSCEAR for construction materials. Some samples obtained values exceeded by up the double this limit, suggesting control and radiometric certification for application of this material

    Regions with different levels of natural radionuclides should be investigated from the radioecological viewpoint, to establish protection criteria for environment and the population. The municipality of São Mamede in the state of Paraiba, is one of the closest of the uranium deposit in Espinharas - PB, and can be influenced, given its geological formation, which justifies conducting environmental dosimetric studies. The United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR) established in 2008 a value for the environmental equivalent effective dose rate of 2.44 mSv / y, considering the different forms of exposure and outdoor environments and internal. The calculation for estimating the outdoor dose rate considered a factor of 0.2, which corresponds therefore to a dose rate of 0.46 mSv / y for these environments. The objective of this study was to determine the levels of natural ionizing radiation that municipality using estimated effective dose rate measured in air and 1.0 m from the surface, points to the presence of rocky outcrops using portable detector with discriminator combined probe of NaI (Tl) and BGO. The experimental setup allowed the evaluation of eighty-one points, dose rates ranged from 0.34 to 4.0 mSv / y, with an average of 0.76 mSv / y, exceeding the global average by a factor of 9, which characterizes the need to investigate the dosimetry for internal environments, which can define criteria to check a possible estimate of radioecological risk.

    In 1983 the authors carried out a survey in the Democratic Republic of São Tomé and Principe, analysing 1050 specimens of stools collected among the population from apparently healthy subjects chosen at random and in a number proportional to the distribution of the population in the regions of the country (about 1% of the population was examined). The examined subjects were divided into 3 age groups (0-3, 4-12, more than 12 years old), to have homogeneous groups in relation principally to modalities of life and nutritional patterns. There were 488 male subjects and 562 females. The survey was preceded by a sensitization of the people to the problem of intestinal parasites and by two preliminary surveys about the number of existing latrines and about people's believes and attitudes in relation to helmintiasis. The tests were made according to the modified Ritchie technique on fecal specimens preserved with 10% formol solution. The following results were found: a) Protozoa: Entamoeba coli, 43.0%; Iodamoeba buetschlii, 9.0%; Giardia intestinalis, 8.8%; Endolimax nana, 7.0%; E. histolytica, 5.5%; E. hartmanni, 2.5%; Chilomastix mesnili, 2.3%; Trichomonas intestinalis, 0.2%; Balantidium coli, 0.1%. b) Helminths: Trichuris trichiura, 87.7%; Ascaris lumbricoides, 64.3%; Ancylostomatidae, 40.5%; Strongyloides stercoralis, 6.8%; Hymenolepis diminuta, 0.3%; H. nana, 0.2%; Schistosoma haematobium, 0.2%. In 28.2% of the specimens (with more than 50% of subjects in some villages) eggs of Heterophyidae were found, very similar to Metagonimus yokogawai, but not yet identified by us, with the following characteristics: elliptical shape, average size 25 mu (22.2-27.7) X 18.5 mu (17-21), thick wall, operculum difficult to see, not sticking out from the outline but visible by focusing being in a different refractiveness, presence of a small polar knob, colour slightly brownish, asymmetric miracidium. Further investigations are necessary to identify the species of this trematode and

  10. Assessment of natural radioactivity levels in waters from the higher Ribeira Valley to the southern Sao Paulo state coastal plain

    International Nuclear Information System (INIS)

    information on the interaction of sediments, groundwater and estuarine waters. In this project, the distribution of natural Ra isotopes was studied in ix surface, groundwater and estuarine water samples collected from dry and wet seasons (2009 - 2010) campaigns performed in Ribeira Valley, Southern Sao Paulo State. The inventory allowed the application of Ra isotopes as tracers of fluvial and groundwater discharges to the Cananeia-Iguape estuarine complex. The exchange of groundwater/surface water in Ribeira do Iguape River basin and related fluxes of several constituents for the Cananeia-Iguape estuarine complex mass balance is still not very well known. The results obtained in this research work evidenced that there is a prevalence of 228Ra isotope in all the set of samples analyzed. However, the activity concentrations of Ra isotopes determined from Higher Ribeira Valley through the Southern Coastal Plain of Sao Paulo are representative of natural background levels, showing low or minimal human intervention. In the set of samples collected along Ribeira do Iguape River, Cananeia and Iguape outlets, the higher concentrations of Ra were observed in bottom waters, indicating the diffusion of 228Ra from sediments recently deposited as a potential source of the increased concentrations of this isotope when compared with others. The activity concentrations of the short-lived Ra isotopes were negligible, lower than the limit of the detection. Fluxes of Ra for Cananeia outlet are strongly influenced by tidal oscillations, which modulate the increase and decrease of Ra concentrations in response of the respective increase and decrease of waters salinity. In Iguape outlet and in hydrochemical stations performed along Ribeira do Iguape River it was observed a linear relationship between the amount of suspended matter and the increase of 228Ra activity concentration. When we evaluate qualitatively the differences in behavior of both long-lived Ra isotopes, the concentrations of 226Ra

    Full Text Available Biomaterial surface functionalization remains of great interest in the promotion of cell osteogenic induction. Previous studies highlighted the positive effects of porous Ti-6Al-4V and phospholipid coating on osteoblast differentiation and bone remodeling. Therefore, the first objective of this study was to evaluate the potential synergistic effects of material porosity and phospholipid coating. Primary human osteoblasts and Saos-2 cells were cultured on different Ti-6Al-4V specimens (mirror-like polished or porous specimens and were coated or not with 1-palmitoyl-2-oleoyl-sn-glycero-3-phosphoethanolamine (POPE for three weeks or five weeks. Selected gene expressions (e.g., classical bone markers: alkaline phosphatase, osteocalcin, osteoprotegerin (OPG, receptor activator of nuclear factor kappa-β ligand (RANKL and runt-related transcription factor 2 were estimated in vitro. Furthermore, the expressions of osteocalcin and osteopontin were examined via fluorescent microscopy at five weeks (immunocytochemistry. Consequently, it was observed that phospholipid coating potentiates preferences for low and high porosities in Saos-2 and primary cells, respectively, at the gene and protein levels. Additionally, RANKL and OPG exhibited different gene expression patterns; primary cells showed dramatically increased RANKL expression, whereas OPG expression was decreased in the presence of POPE. A synergistic effect of increased porosity and phospholipid coating was observed in primary osteoblasts in bone remodeling. This study showed the advantage of primary cells over the standard bone cell model.

  13. Raw material of the Corumbatai formation at the region of ceramic pole of Santa Gertrudes - Sao Paulo, Brazil, with natural characteristics for fabrication of expanded clay

    International Nuclear Information System (INIS)

    This paper refers to the study of the bases material of the Corumbatai Formation (Parana Basin) from a clay mine, which presents limits for its use in ceramic tiles in dry grinding process due to its hardness and, especially, the high content of organic matter in relation to the clay overlaid. The characterization of the raw material and the product was accomplished by organic carbon analysis, X-ray diffraction, optical microscopy and test-firing. Firing conditions were determined to get expanded clay, using fast firing static kiln and a continuous roller kiln, both from laboratory equipment, getting samples with variable density up to the limit of expansion, with density that can reach values lower than 0,5g.cm-3 because of the formation of closed pores and an external vitreous foil which provide a high mechanical resistance to the particles.

    Developmental changes in regional cerebral blood flow (CBF) were determined using radioactively labeled microspheres to measure flow to the cortex, brain stem, cerebellum, white matter, caudate nucleus, and choroid plexus in three groups of chronically catheterized lambs under physiological conditions: 90- to 100-day preterm fetal lambs (n = 14), 125- to 136-day near-term fetal lambs (n = 11), and newborn lambs 5-44 days old (n = 10). We continually monitored heart rate, central venous pressure, and mean arterial blood pressure (MAP) and periodically measured arterial blood O2 and CO2 tensions (PaO2, PaCO2, respectively), pH, hemoglobin, and oxygen saturation (SaO2). The regional CBF measurements (ml.100 g-1.min-1) revealed that in all three age groups the high flow areas are the choroid plexus and caudate nucleus, whereas the lowest flow area is the white matter. There is, however, a different hierarchy of regional CBF in utero (cortex less than cerebellum and brain stem) compared with extrauterine life in the newborn lamb (cortex and cerebellum greater than brain stem). Analysis of regional cerebral oxygen delivery [CBF times arterial oxygen content (CaO2)] demonstrated a progressively increasing oxygen transport to the cortex with increasing gestational maturity and after birth. Oxygen transport to the brain stem, cerebellum, and white matter increased with gestational age, but did not increase after birth. Relationships between regional CBF and natural physiological variations of cardiorespiratory parameters (PaO2, SaO2, CaO2, pH, PaCO2, and MAP) were assessed using regression analysis. Correlations of regional CBF with PaO2 and SaO2 suggest that cerebral perfusion is not primarily determined by CaO2 when variations occur within the physiological range.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:3337259

    Long-term demand forecasts (up to 2025) are presented in this paper for the main energy forms consumed in the residential, trade and services, rural, transport, and industrial sectors in the State of Sao Paulo. They were obtained with the help of a flexible forecasting model based on the structural decomposition of the demand, for three alternative scenarios concerning the growth of the state economy. These three state-wise scenarios are related to initially nation-wide defined scenarios, through assumptions concerning the evolution on the ratio between the state GDP and the national GDP.

    Sao Mateus field is located onshore Espirito Santo basin, Brazil eastern cost. Petroleum accumulations occur in Mucuri Member, Aptian, deposited at the end of basin rift phase. Vertical section of this member records a transition from a continental to a shallow marine environment. Three depositional sequences are recognized. Each sequence consists of lowstand fluvial deposits covered by transgressive deposits with delta estuarine fine grained sediments. The highly transgressive sedimentation pattern makes difficult to discern transgressive to highstand deposits. The reservoirs are fluvial and delta estuarine sandstones, and the seals are transgressive fine grained sediments. Normal faults promoted up-dip closures. (author)

  18. Utilization of agricultural raw material as an energy source - a case study on the alcohol industry in Sao Paulo state, Brazil

    International Nuclear Information System (INIS)

    The Brazilian National Alcohol Programme (Proalcool) can well be considered the world's largest technical effort to replace petroleum with fuels from plant biomass: 11.5 billion liters of alcohol for fuel and industrial use were produced in the harvest of 1987/88. About 3.7 million of the 13 million Brazilian cars run on straight hydrous alcohol, the rest on gasohol (gasoline blend with up to 22% anhydrous alcohol). The following survey is focused on Sao Paulo State, which is responsible for 64% of Brazil's alcohol production (7.33 billion liters). In this state alcohol from sugarcane is produced in the largest (average 370.000 1/day) and technically most effective production units, at lowest production costs. This paper attempts to estimate via simulation the future productivity and cost of fuel alcohol, and evaluates its market position compared to energy of fossil origin. (author)

  19. Total diet study in Sao Paulo State: estimation of dietary intakes of toxic (arsenic and cadmium) and essential elements (calcium, chromium, iron, selenium, sodium, potassium and zinc)

    International Nuclear Information System (INIS)

    Total Diet Study (TDS) is based on the evaluation of food samples representing a market basket, which shows dietary habits of a given population. The World Health Organization (WHO) has encouraged countries to conduct their own TDS, which is already being done in several countries, but not yet in Brazil. This study involved essential steps to establish a TDS in Sao Paulo State: a) information about food consumption (a recent national household food budget survey 'POF 2002-2003' by the Brazilian Institute for Geography and Statistics (IBGE), including 5,440 foods); b) development of a Market Basket (sampling of 71 foods consumed more than 2g/day/person, grouped into 30 food groups: cereals; leguminous; leafy, fruity and tuberous vegetables; tropical fruits; other fruits; flours; pasta; breads; biscuits; prime and standard grade beef; pork meat; sausages; poultry; milk/cream; other dairy products; sugars; sweet dishes; salts, sauces; oils, fats, alcoholic beverages; non-alcoholic beverages; coffee; ready-made dishes; seawater and freshwater fishes); c) collection and kitchen preparation in restaurants of the Food service Department of the Coordination of Social Assistance of the University of Sao Paulo (preparing ready-to- consume foods, individually and mixing foods of the same food group); d) chemical analysis (food groups were homogenized, pulverized and analyzed by Instrumental Neutron Activation and GF Atomic Absorption Spectroscopy). Element contents were determined in the 30 food groups. Average element range concentrations and daily dietary intakes were determined. The results of daily dietary intakes in this study (275±31mg Ca; 20.7±1.9μg Cr; 5.7±0.4mg Fe; 861±46mg K; 9.44±0.48μg Se; 1928±278mg Na; 4.25±0.24mg Zn; 1.53±0.43μg As and 1.31±0.16μg Cd) were lower than or similar the results of other Brazilian studies and lower than results of TDS of other countries. This is probably due to the fact that the Market Basket of this study represented

  20. Determination of rare earth elements in Solanum lycocarpum in 'Cerrado de Emas'- Pirassununga, State of Sao Paulo, Brazil, by neutron activation analysis

    International Nuclear Information System (INIS)

    In the present work, the rare earth elements concentration (REE) in plant leaves of the species Solanum lycocarpum from 'Cerrado de Emas', Pirassununga, Sao Paulo, and the soil where they have grown up, was determined by using instrumental neutron activation analysis. The obtained values for most of the light REE (La, Ce, Nd) were higher than the reference values for REE in plants. These results suggest that the light REE are more available in the soil than the heavy REE. The concentration of REE in the plant and the soil were normalized to chondrite contents, showing in the soil diagram a negative anomaly for the concentration of Eu and a positive anomaly for the concentration of Ce, which were not observed in the plant diagram.

  1. Cytocompatibility property evaluation of gas pressure sintered SiAlON–SiC composites with L929 fibroblast cells and Saos-2 osteoblast-like cells

    International Nuclear Information System (INIS)

    Although the oxide ceramics have widely been investigated for their biocompatibility, non-oxide ceramics, such as SiAlON and SiC are yet to be explored in detail. Lack of understanding of the biocompatibility restricts the use of these ceramics in clinical trials. It is hence, essential to carry out proper and thorough study to assess cell adhesion, cytocompatibility and cell viability on the non-oxide ceramics for the potential applications. In this perspective, the present research work reports the cytocompatibility of gas pressure sintered SiAlON monolith and SiAlON–SiC composites with varying amount of SiC, using connective tissue cells (L929) and bone cells (Saos-2). The quantification of cell viability using MTT assay reveals the non-cytotoxic response. The cell viability has been found to be cell type dependent. An attempt has been made to discuss the cytocompatibility of the developed composites in the light of SiC content and type of sinter additives. - Highlights: ► SiAlON and SiAlON–SiC composite can be used as substrate for the proliferation of L929 mouse fibroblast and Saos-2 osteoblast-like cells. ► Addition of SiC to SiAlON matrix does not degrade cytocompatibility property. ► The cell viability of the SiAlON–SiC is found to be cell type dependent. ► The use of Yb–Sm–Ca as sinter-aid appears to degrade cell viability of L929 cells.

  2. Evaluation of the impact of farming activity in the water quality in surface catchment areas in hydrographic basin from Mogi-Guacu and Pardo Rivers, Sao Paulo

    International Nuclear Information System (INIS)

    This study was performed in 10 small basins located in the Mogi-Guacu and Pardo Rivers, in the Northeastern area of Sao Paulo State. The land belonging of these basins is used to grow row crops of potato, coffee and pasture areas. This study aimed to characterize small basins, to evaluate water and sediment quality and to correlate basic aspects of climatology, hydrology, toxicology and land uses to the physical, chemical and toxicological characteristics of the water in the streams. Geographic Information System (GIS) was used as a tool of evaluation of land uses and risk assessment was performed for a final evaluation. The samplings were carried out from June/1999 to June/2000 in the 13 collecting points. It was verified that water quality is dependent upon the rainy and dry periods and the harvest periods. In the beginning of rainy periods were found large concentrations of metals and traces of herbicides leachate from soil and, in the dry period the same event was verified, caused by concentration of the water. In August, September and October phosphorus concentrations were very low getting an improvement in the water quality. Al, Fe and Mn are majority elements of chemical compositions of rocks of the study area, and exceed the Brazilian Guidelines. The stream waters were classified as 44% oligotrophic, 42% mesotrophic and 14% eutrophic. Jaguari-Mirim River presented the largest values of Trophic Index (TI). Sediment analyses showed a great variety of organic compounds coming from anthropogenic activities (industrial and farming activity). Toxicity tests with hyalella azteca in the sediments presented toxicity for sediments from Sao Joao da Boa Vista and Divinolandia. A methodology was developed for organochlorinated pesticides by gas chromatography coupled to mass spectrometry (GCMS). The presence of organochlorinated pesticides was not verified. (author)

    The objective of this work is to evaluate the impact of vehicular emissions on the formation of fine particles (PM2.5; ≤ 2.5 µm in diameter) in the Sao Paulo Metropolitan Area (SPMA) in Brazil, where ethanol is used intensively as a fuel in road vehicles. The Weather Research and Forecasting with Chemistry (WRF-Chem) model, which simulates feedbacks between meteorological variables and chemical species, is used as a photochemical modelling tool to describe the physico-chemical processes leading to the evolution of number and mass size distribution of particles through gas-to-particle conversion. A vehicular emission model based on statistical information of vehicular activity is applied to simulate vehicular emissions over the studied area. The simulation has been performed for a 1-month period (7 August-6 September 2012) to cover the availability of experimental data from the NUANCE-SPS (Narrowing the Uncertainties on Aerosol and Climate Changes in Sao Paulo State) project that aims to characterize emissions of atmospheric aerosols in the SPMA. The availability of experimental measurements of atmospheric aerosols and the application of the WRF-Chem model made it possible to represent some of the most important properties of fine particles in the SPMA such as the mass size distribution and chemical composition, besides allowing us to evaluate its formation potential through the gas-to-particle conversion processes. Results show that the emission of primary gases, mostly from vehicles, led to a production of secondary particles between 20 and 30 % in relation to the total mass concentration of PM2.5 in the downtown SPMA. Each of PM2.5 and primary natural aerosol (dust and sea salt) contributed with 40-50 % of the total PM10 (i.e. those ≤ 10 µm in diameter) concentration. Over 40 % of the formation of fine particles, by mass, was due to the emission of hydrocarbons, mainly aromatics. Furthermore, an increase in the number of small particles impaired the

    Full Text Available An investigation was made of the adhesion, growth and differentiation of osteoblast-like MG-63 and Saos-2 cells on titanium (Ti and niobium (Nb supports and on TiNb alloy with surfaces oxidized at 165°C under hydrothermal conditions and at 600°C in a stream of air. The oxidation mode and the chemical composition of the samples tuned the morphology, topography and distribution of the charge on their surfaces, which enabled us to evaluate the importance of these material characteristics in the interaction of the cells with the sample surface. Numbers of adhered MG-63 and Saos-2 cells correlated with the number of positively-charged (related with the Nb2O5 phase and negatively-charged sites (related with the TiO2 phase on the alloy surface. Proliferation of these cells is correlated with the presence of positively-charged (i.e. basic sites of the Nb2O5 alloy phase, while cell differentiation is correlated with negatively-charged (acidic sites of the TiO2 alloy phase. The number of charged sites and adhered cells was substantially higher on the alloy sample oxidized at 600°C than on the hydrothermally treated sample at 165°C. The expression values of osteoblast differentiation markers (collagen type I and osteocalcin were higher for cells grown on the Ti samples than for those grown on the TiNb samples. This was more particularly apparent in the samples treated at 165°C. No considerable immune activation of murine macrophage-like RAW 264.7 cells on the tested samples was found. The secretion of TNF-α by these cells into the cell culture media was much lower than for either cells grown in the presence of bacterial lipopolysaccharide, or untreated control samples. Thus, oxidized Ti and TiNb are both promising materials for bone implantation; TiNb for applications where bone cell proliferation is desirable, and Ti for induction of osteogenic cell differentiation.

    Full Text Available General survey of inland fisheries and aquaculture in the state of Sao Paulo Brazil. Brazil disposes of huge water resources which are well exploited for the production of electricity. On the other hand, fisheries and aquaculture have not been developed yet in spite of important research. The state of Sao Paulo is a typical example of this with, in addition, serious pollution problems. This very crowded state with high unemployment rate disposes of large stretches of water and non-exploited rivers. In order to make up for the protein shortage of some classes of the society, it is suggested to improve the environment by fisheries. It will be possible to develop aquaculture as long as we have techniques which are reliable, profitable integrated with agriculture, a competent staff, a change in food habits towards a larger consumption of fish and eventually we can create a packaging and trading circuit that will provide easy selling of the commodity.

    This article relates the development of a research about low cost for rural electrification projects, which have been used like a base to develop a technical analysis in whole projects of the program 'Luz para Todos'. This program was made in 2002 with the purpose to offer electricity for whole people in Brazilian rural area. This method was developed seeking in to achieve cost reduction in the planning made by electric companies in Sao Paulo state. At first, were analyzed the rural electric projects made by electricity companies in the program 'Luz da Terra', in front of to the commitment in achieving cost reduction in the rural electric projects. The program 'Luz da Terra' was made whit a social purpose and it was developed in the whole Sao Paulo state, during 1996 until 2004. One of the main demands to achieve reasonable costs and to allow the program's viability was the previous analyses of rural distribution projects, before them changing to work of electricity, checking out if they had well defined. social, technical and economics methods. For that, were chosen quantitative and non-quantitative indicators, agreement whit a comparative analysis of each company performance in the program 'Luz da Terra', in agreement whit historical series, based on the group of the final result of each distribution electricity project. In a second moment, the same methodology was adjusted to confront the plans data of each company's future works in the program 'Luz para Todos', using the results of the first program. The research allowed the identification of some planner's tendencies when developing from a more rigorous model of low cost, like was the program 'Luz da Terra', to the actual program 'Luz para Todos'. Applied to all companies in the Sao Paulo state, the study served as a support to renegotiate budgets, what provided savings of more than US$ 10,000.000 in a total of 42

    This paper presents the results obtained from surface and borehole geophysical investigations carried out at the Shallow Geophysical Test Site of IAG-USP. The main objective was to characterize the sediments and the top of basement. The area is constituted by sandy-clay sediments of Sao Paulo Basin (Sao Paulo and Resend Formations) on the granite-gneiss basement with different degrees of weathering. In the area of studies, three boreholes were drilled for geological and geophysical research purposes (pioneer in Brazil). These boreholes were used to verify the stratigraphy, to collect the sample for laboratory measurements, to calibrate the results of surface geophysics and to carry out well logging. The surface methods used were: seismic (reflection and refraction), electric-resistivity (profiling and vertical electric sounding) and GPR-Ground Penetrating Radar. The integration of results show excellent agreement and allow constructing a geological-geophysical model for the site which is at the border of Sao Paulo sedimentary basin. Moreover, the various geophysics methods, commonly used in geological, geotechnical and environmental researches, have been tested under controlled conditions. (author)

    International Nuclear Information System (INIS)

    Aiming the determination of the Hg concentration and the As, Cr and Zn trace elements, four commercial available and frequently consumable fishes by the Cananeia, Sao Paulo, Brazil, were analysed. A total of 53 samples were evaluated as follows: jew fish (Micropogonias furnieri), hake (Macrodon ancylodon), perch (Centropomus undecimalis), and grey mullet (Mugil platanus), all acquired at local fishmonger. The atomic absorption and neutron activation analysis techniques were used for the determination of Hg total levels and trace elements respectively. The trace elements presented large concentration variation among the same specie and the species performed as well. The jew fish presented levels superior to 1000 μg kg-1 for the most individuals analysed and the perch presented chromium levels exceeding the limit of 0.10 mg kg-1 for some individuals. The level of Zn presented values below 50 mg kg-1 established by the Brazilian legislation for all species. The Zn total contents among all species presented values bellow the limits of the Brazilian legislation (500 μg kg-1 for the predator species and 1000 μg kg-1 for the predator species)

    作为屈原形象特征的“高冠长剑”,并不是诗人用以表示自己异于众人的服饰,其只是楚国的普通士服,但却有着通神的象征意义,是楚地祭祀文化的集中体现。在诗中“高冠长剑”具有双重含义,既指通神,又喻美德。%The lofty headdress and lengthwise pendent, which are always considered as the unique appearance of Qu Yuan, don't show that they are different from the other intellects' raiment. They are just the ordinary raiment of the intellects of Chu nation, which however symbolize the communion between human and divinity and represent the witchcraft and memorial culture of Chu nation. In Li Sao, the lofty headdress and lengthwise pendent possess connotations of the communion between human and divinity and virtue.

    Full Text Available Abstract Background Both violence and depression during pregnancy have been linked to adverse neonatal outcomes, particularly low birth weight. The aim of this study was to investigate the independent and interactive effects of these maternal exposures upon neonatal outcomes among pregnant adolescents in a disadvantaged population from Sao Paulo, Brazil. Methods 930 consecutive pregnant teenagers, admitted for delivery were recruited. Violence was assessed using the Californian Perinatal Assessment. Mental illness was measured using the Composite International Diagnostic Interview (CIDI. Apgar scores of newborns were estimated and their weight measured. Results 21.9% of mothers reported lifetime violence (2% during pregnancy and 24.3% had a common mental disorder in the past 12 months. The exposures were correlated and each was associated with low education. Lifetime violence was strongly associated with Common Mental Disorders. Violence during pregnancy (PR = 2.59(1.05–6.40 and threat of physical violence (PR = 1.86(1.03–3.35 and any common mental disorders (PR = 2.09 (1.21–3.63 (as well as depression, anxiety and PTSD separately were independently associated with low birth weight. Conclusion Efforts to improve neonatal outcomes in low income countries may be neglecting two important independent, but correlated risk factors: maternal experience of violence and common mental disorder.

  15. Distribution of 226Ra, 232Th and 40K in soils and sugar cane crops at Corumbatai river basin, Sao Paulo State, Brazil

    International Nuclear Information System (INIS)

    The common use of phosphate fertilizers NPK and amendments in sugar cane crops in Brazilian agriculture may increase the 226Ra, 232Th and 40K activity concentrations in soils and their availability for plants and human food chain. Thus, the main aim of this study was to evaluate the distribution of 226Ra, 232Th and 40K in soils and sugar cane crops in the Corumbatai river basin, Sao Paulo State, Brazil. The gamma spectrometry was utilized to measure the 226Ra, 232Th and 40K activity concentration in all samples. The soil-to-sugar cane transfer factors (TF) were quantified using the ratio between the radionuclide activity concentration in sugar cane and its activity concentration in soil. The results show that, although radionuclides incorporated in phosphate fertilizers and amendments are annually added in the sugar cane crops, if utilized in accordance with the recommended rates, their use does not lead to hazards levels in soils. The soil-to-sugar cane transfer of radionuclides occurred in the following order 40K>226Ra>232Th. Therefore, under these conditions, radionuclides intake through consumption of sugar is not hazardous to human health.

    The point of zero salt effect (PZSE) is the soil pH value at which the magnitude of the variable surface charges is not changed due to variations in the ionic concentration of the soil solution. This property influences not only electrochemical phenomena occurring at the solid-solution interface but also the flocculation degree of the soil particles. In this study we investigated the relationships between the clay mineralogy and the PZSE values of representative soils of the Sao Paulo State, Brazil. The results confirmed the usefulness of the difference between the soil pH values measured in 1 mol L-1 KCl (pHKC1) and in water (pHH2O) (2 pHKC1 - pHH2O) for estimating the PZSE of tropical soils, except for the ones rich in exchangeable Al; furthermore, the △pH index (pHKCI - pHH2O) was highly correlated with the difference between the PZSE and pHH2O values, reiterating the △pH utility for estimating both the signal and the magnitude of the net surface charge of tropical soils. Finally, correlation and multiple regression analyses showed that the PZSE value of weathered non-allophanic tropical soils tends to increase and to equal the soil pH due to the weathering-induced kaolinite destabilization and concomitant Fe- and Al-oxide accumulation.

    In order to elucidate the mechanisms involved in the process of uranium leaching due to the rock-water interaction in the granitic rocks from Itu Complex (Sao Paulo, Brazil), an experimental arrangement was developed and built. About 2.5kg of crushed rock fragments from Cabreuva and Indaiatuba Intrusions were maintained at room temperature within a glass flask filled with circulating water. The percolating water was removed periodically (from 10 to 30 days) for uranium analysis and then replaced by an equal volume of fresh water. Alpha spectrometry was used to determine the activity concentrations of {sup 234}U and {sup 238}U, and {sup 234}U/{sup 238}U activity ratios, of the waters as well as of the granites. The results for both samples showed that most of the uranium is leached in the first days after the contact between rock and water. The {sup 234}U/{sup 238}U activity ratios were significantly greater than unity, indicating radioactive disequilibrium between those isotopes, probably due to alpha recoil. Although the uranium activity concentrations in the water samples diminished with the increasing of time, it was not observed considerable variations of the {sup 234}U/{sup 238}U activity ratios. It was also noticed that, the amount of leached uranium as well as the {sup 234}U/{sup 238}U activity ratios are characteristics of each sample submitted to leaching, reflecting the differences of the granite facies mineralogy.(author)

    Contaminated sites by NAPL (Non-Aqueous Phase-Liquids) may lead to safety risks to human health and to ecosystems, restrictions to urban development and decrease of real estate value. This work used the radon gas as an indicator for the analysis of subsurface soil gas, once this noble gas presents good solubility in a wide range of NAPL, being partially retained in the NAPL contamination. Therefore, a decrease of the activity of radon in the contaminated soil gas can be expected, due to the high capacity of partitioning of radon in NAPL, which allows that the NAPL retain part of the radon previously available in the soil pores. The survey was carried out at a disused industry, contaminated by low volatile NAPL, located at east of Sao Paulo city, in March/2015. Radon was evaluated by passive detection methodology with CR-39 solid state nuclear track detectors (SSNTD). Radon concentrations for the eight monitoring stations at non-contaminated locations in March/2015 varied from 16.4 ± 1.2 kBq.m{sup -3} to 55 ± 4 kBq.m{sup -3}. For the two monitoring stations assumed as contaminated locations in March/2015, radon concentrations were 1.17 ± 0.08 kBq.m{sup -3} and 4.2 ± 0.3 kBq.m{sup -3}, diminished in a range from 92% to 98% when compared with the results for the non-contaminated areas.

  19. In vitro behavior of human osteoblast-like cells (SaOS2) cultured on surface modified titanium and titanium-zirconium alloy

    International Nuclear Information System (INIS)

    In this study, titanium (Ti) and titanium-zirconium (TiZr) alloy samples fabricated through powder metallurgy were surface modified by alkali-heat treatment and calcium (Ca)-ion-deposition. The alteration of the surface morphology and the chemistry of the Ti and TiZr after surface modification were examined. The bioactivity of the Ti and TiZr alloys after the surface modification was demonstrated. Subsequently, the cytocompatibility of the surface modified Ti and TiZr was evaluated via in vitro cell culture using human osteoblast-like cells (SaOS2). The cellular attachment, adhesion and proliferation after cell culture for 14 days were characterized by scanning electron microscopy (SEM) and MTT assay. The relationship between surface morphology and chemical composition of the surface modified Ti and TiZr and cellular responses was investigated. Results indicated that the surface-modified Ti and TiZr alloys exhibited excellent in vitro cytocompatibility together with satisfactory bioactivity. Since osteoblast adhesion and proliferation are essential prerequisites for a successful implant in vivo, these results provide evidence that Ti and TiZr alloys after appropriate surface modification are promising biomaterials for hard tissue replacement. Highlights: → Titanium (Ti) and titanium-zirconium (TiZr) alloy for load-bearing implant applications. → Implant applications. → Alkali-heat treatment and calcium (Ca)-ion-deposition as surface modification methods. → Surface modified Ti and TiZr exhibited excellent biocompatibility and bioactivity.

    The coastal areas located in the northern coast of the Rio Grande do Norte State, specifically between the districts of Galinhos e Sao Bento do Norte, characterized by constant processes of coastal and eolic transport, causing erosion, alterations in the sediments and modifications in the coast line. Beyond of those natural factors, there is the proximity to Polo Petrolifero of Guamare, the largest terrestrial producer of petroleum of Brazil. The first part of that work consisted of to elaborate and to develop a Geographical Database (BDG), to store all the existent data of the study area, such as geological and geophysical data, hydrodynamic data, products of remote sensing, thematic maps, among others. The second stage of this work aimed to develop starting from the data previously stored in BDG, Oil-Spill Environmental Sensitivity Maps (Maps SAO). Those maps evaluate the reaction of the certain place if to happen an oil spill in her, supplying necessary information to the decision in cleaning and removal of the spilled oil. In that way, Maps SAO of the study area were elaborated in different teams to evaluate if there would be change of the behavior of the coast in the presence of the oil. (author)

    In spite of the high Brazilian levels of solar irradiation and the constructive pattern of Alphaville region, which possess a large concentration of high incoming households, use of solar water heating is still not regulated in neither of its comprising municipalities. Nowadays, the search for savings, diffusion of related technologies and raising environmental awareness have led to voluntary up taking of such systems. However, regulation of solar collectors still lacks integration with certification of sustainable building practices, which does not relate to architectonic factors, in particular to main urbanistic features present in each given installation site. Potential for solar heating in the fully regulated gated areas is estimated to add up to 6,000 MWh/year. Authors suggest that such potential be put to sustainable use in a setting in which solar energy and architecture and urbanism are jointly addressed to; and debate on state and federal regulations and certification of buildings as a whole, in order to neatly integrate active solar systems to the plumbing, so avoiding adverse impacts on water consumption and usage of built spaces, that could lead (through the urbanistic and climatic interfaces) to medium and long term environmental consequences on the availability of solar energy itself.

    Full Text Available Global dengue virus spread in tropical and sub-tropical regions has become a major international public health concern. It is evident that DENV genetic diversity plays a significant role in the immunopathology of the disease and that the identification of polymorphisms associated with adaptive responses is important for vaccine development. The investigation of naturally occurring genomic variants may play an important role in the comprehension of different adaptive strategies used by these mutants to evade the human immune system. In order to elucidate this role we sequenced the complete polyprotein-coding region of thirty-three DENV-3 isolates to characterize variants circulating under high endemicity in the city of São José de Rio Preto, Brazil, during the onset of the 2006-07 epidemic. By inferring the evolutionary history on a local-scale and estimating rates of synonymous (dS and nonsynonimous (dN substitutions, we have documented at least two different introductions of DENV-3 into the city and detected 10 polymorphic codon sites under significant positive selection (dN/dS > 1 and 8 under significant purifying selection (dN/dS < 1. We found several polymorphic amino acid coding sites in the envelope (15, NS1 (17, NS2A (11, and NS5 (24 genes, which suggests that these genes may be experiencing relatively recent adaptive changes. Furthermore, some polymorphisms correlated with changes in the immunogenicity of several epitopes. Our study highlights the existence of significant and informative DENV variability at the spatio-temporal scale of an urban outbreak.

    Full Text Available SUMMARY This study aimed at estimating the number of cases of non-negative serological reactions to Chagas disease in blood donors at the Blood Center of Botucatu, São Paulo, Brazil, from 2003 to 2010 and at relating them to their cities of origin. Five hundred and seventy-four non-negative results for Chagas disease were evaluated. Of these, 371 (64.8% were reagent, and 203 (35.4% were inconclusive. The prevalence of Chagas disease in blood donors was 0.05%. There were, on average, 72 cases/year, and a prevalence of males was observed (64.8%. Forty-three (7.49% individuals were 18 to 30 years old; 92 (16.02% were 31 to 40; 147 (25.61% 41 to 50, and 292 (50.87% were older than 50 years. It was observed that 29.3% of females with reagent serology were at their fertile age (18 and 45 years. The majority of donors were originally from cities in the southwestern and central regions of São Paulo, but individuals from other states contributed with 20%. The provenance of most donors was the city of Botucatu/SP, followed by the city of Taquarituba/SP. Therefore, the profile of donors at this blood center favors the occurrence of a larger number of non-negative serological reactions. Although there has been a significant reduction in the number of new cases/year for this disease, it is still a public-health problem, and results suggest the need for new epidemiological assessments in the studied region.

    In the present study, sediment samples from the Tiete River were evaluated for toxicity and trace metals (5 sampling sites). The studied region includes Salesopolis to Suzano and surroundings, a highly industrialized area. The study involved toxicity evaluation (sediment, elutriate and pore-water) and the distribution of some major, trace and rare earth elements on sediments. Multielemental analysis was carried out by instrumental neutron activation analysis (INAA) and total mercury by cold vapor atomic absorption technique (CV AAS). The concentration values obtained for the metals As, Cr, Hg and Zn in the sediment samples were compared to the Canadian Council of Minister of the Environment (CCME) oriented values (TEL and PEL). Regarding toxicity, whole sediments and elutriate fractions were evaluated using chronic assays for Ceriodaphnia dubia, while the pore water was carried out for Vibrio fischeri toxicity assays. These assays followed Brazilian Standardized Methods (ABNT). Whole sediments and elutriate evidenced negative biological effects, even at Salesopolis county, the control site (less impacted area). The worst effects were obtained at Mogi das Cruzes and Suzano counties (sampling stations 3 and 4). The elutriate fractions collected at the same stations showed acute toxicity in two of three samples (C. dubia). When pore water was evaluated, a toxicity gradient which increased as the river flowed through Mogi das Cruzes county was obtained. Regarding toxic metal contents in the sediment samples points 3 and 4 exceeded the TEL oriented values for As, Cr, Hg and Zn and point 4 also exceeded the PEL values for all these elements. (author)

    Full Text Available A associação entre SAOS e a síndrome metabólica é reconhecida, sendo denominada síndrome Z. Os critérios para a síndrome metabólica incluem pelo menos três dos seguintes fatores: obesidade central (circunferência da cintura > 102 cm em homens e > 88 cm em mulheres; triglicérides > 150 mg/dL; HDL colesterol 130/85 mmHg; e glicemia de jejum > 100 mg/dL. A obesidade central esta associada a SAOS e síndrome metabólica, havendo evidências de que a apneia do sono seja um fator de risco independente da obesidade, intolerância à glicose e resistência insulínica. Embora a obesidade central seja um fator de risco para ambas as condições, há evidências de que a apneia do sono seja um fator de risco independente para a intolerância à glicose e a resistência à insulina. Os mecanismos implicados decorrem da ativação do sistema nervoso simpático e do eixo hipotálamo-hipófise-adrenal; da ativação de fatores pró-inflamatórios, como IL-6 e TNF-α; e da diminuição dos níveis de adiponectina mediados principalmente pela hipoxemia intermitente relacionada às apneias. Apesar dessas evidências, os resultados dos estudos são controversos em relação aos benefícios do tratamento da apneia do sono com CPAP nas alterações metabólicas. Adicionalmente, os poucos estudos que abordaram a apneia do sono obstrutiva como um fator de risco para as dislipidemias apresentaram resultados discordantes. Estudos controlados, populacionais e longitudinais são necessários para esclarecer a interação entre a apneia do sono e as consequências metabólicas no sentido de se tratar adequadamente esses indivíduos.There is a recognized association between obstructive sleep apnea syndrome and metabolic syndrome, designated syndrome Z.

    Full Text Available We are witnessing the growth of urban populations, particularly in the developing world. São Paulo, the largest city in South America, continues to grow, and this growth is dramatically effecting the environment and human health. The aim of this study was to estimate the point prevalence of chronic pain in São Paulo city dwellers and to explore the influence of aspects related to urbanicity.A two-stage cluster randomized sample included 1100 individuals of the city of Sao Paulo, representing the population proportionally in terms of gender, age and social classes in 2007. For this observational cross-sectional study, the household sample was interviewed using validated questionnaires for sociodemographic aspects, the Beck inventories for anxiety and depression, the WHOQoL-REF for quality of life, the Chalder Fatigue Scale. Musculoskeletal pain was defined as diffuse pain or pain located in the back, joints or limbs. Data regarding sleep complaints and polysomnography were obtained from the Epidemiologic Sleep Study conducted in São Paulo city in 2007.The prevalence estimate of chronic musculoskeletal pain was approximately 27%, with a female/male ratio of approximately 2.6/1. The predictors were being in the age-range of 30-39 years, low socioeconomic and schooling levels, obesity, sedentarism, fatigue, non-restorative sleep, daytime sleepiness, poor sleep quality, poor life quality, anxiety and depression symptoms. Psychological wellbeing was the main discriminator between responders with chronic musculoskeletal pain and the controls, followed by depression for the participants with poor psychological wellbeing, and fatigue, for the remaining ones. Insomnia syndrome was the third-level discriminator for those with fatigue, whereas sleep quality for those without fatigue.Musculoskeletal pain was frequently reported by São Paulo city dwellers and its correlates with psychological and sleep aspects are suggestive of a response to urbanicity

  7. Association between micronuclei frequency in pollen mother cells of Tradescantia and mortality due to cancer and cardiovascular diseases: A preliminary study in Sao Jose dos Campos, Brazil

    International Nuclear Information System (INIS)

    The present study was designed to explore the correlation between the frequency of micronuclei in Trad-MN, measured across 28 biomonitoring stations during the period comprised between 11 of May and 2 of October, 2006, and adjusted mortality rates due to cardiovascular, respiratory diseases and cancer in Sao Jose dos Campos, Brazil, an area with different sources of air pollution. For controlling purposes, mortality rate due to gastrointestinal diseases (an event less prone to be affected by air pollution) was also considered in the analysis. Spatial distribution of micronuclei frequency was determined using average interpolation. The association between health estimators and micronuclei frequency was determined by measures of Pearson's correlation. Higher frequencies of micronuclei were detected in areas with high traffic and close to a petrochemical pole. Significant associations were detected between micronuclei frequency and adjusted mortality rate due to cardiovascular diseases (r = 0.841, p = 0.036) and cancer (r = 0.890, p = 0.018). The association between mortality due to chronic obstructive pulmonary diseases was positive but did not reach statistical significance (r = 0.640, p = 0.172), probably because of the small number of events. Gastrointestinal mortality did not exhibit significant association with micronuclei frequency. Because the small number of observations and the nature of an ecological study, the present findings must be considered with caution and considered as preliminary. Further studies, performed in different conditions of contamination and climate should be done before considering Trad-MN in the evaluation of human health risk imposed by air pollutants. - Bioassay used to explore the correlation between air pollution exposition and mortality rates.

    In the present study the preliminary results for the Promissao reservoir, situated in the Lower Tiete region covering a little more than 1% of the SP state population, is characterized by intense agropastoral activities. Its operations for generating electrical energy started in 1975. It is located at Tiete River and its hydrographic basin has a drainage area of 530 km{sup 2}. The total extension of the reservoir is 110 km along the Tiete River, with a medium depth of 20 m. A core sampler was used and a 33 cm sediment core was collected from the dam in January 2013, sliced at every 2.5 cm, totaling 13 samples. Instrumental neutron activation analysis was applied to the sediment samples in order to determine some major (Fe, K, and Na), trace (As, Ba, Br, Co, Cr, Cs, Hf, Rb, Sb, Sc, Ta, Tb, Th, U, and Zn) and rare earth elements (Ce, Eu, La, Lu, Nd, Sm, Tb, and Yb). The enrichment factor (EF) was applied to the results obtained by using North American Shale Composite, Upper Continental Crust and the concentration values of the last layer of this profile as reference values for sediment contamination index assessment.

    The traditional energy planning usually takes into account the technical economical costs, considered alongside environmental and a few political restraints; however, there is a lack of methods to evenly assess environmental, economical, social and political costs. This work tries to change such scenario by elaborating a model to characterize an energy resource in all four dimensions - environmental, political, social and economical - in an integrated view. The model aims at two objectives: provide a method to assess the global cost of the energy resource and estimate its potential considering the limitations provided by these dimensions. To minimize the complexity of the integration process, the model strongly recommends the use of the Full Cost Accounting - FCA - method to assess the costs and benefits from any given resource. The FCA allows considering quantitative and qualitative costs, reducing the need of quantitative data, which are limited in some cases. The model has been applied in the characterization of the region of Aracatuba, located in the west part of the state of Sao Paulo - Brazil. The results showed that the potential of renewable sources are promising, especially when the global costs are considered. Some resources, in spite of being economically attractive, don't provide an acceptable global cost. It became clear that the model is a valuable tool when the conventional tools fail to address many issues, especially the need of an integrated view on the planning process; the results from this model can be applied in a portfolio selection method to evaluate the best options for a power system expansion. It has to be noticed that the usefulness of this model can be increased when adopted with a method to analyze demand side management measures, thus offering a complete set of possible choices of energy options for the decision maker.

  11. Provenience studies in archaeological sites in Araruama region, Rio de Janeiro State, Brazil

    International Nuclear Information System (INIS)

    The present work shows the results of provenience studies for ceramics collected at Sao Jose, Morro Grande, Serrano and Bela Vista archaeological sites in Araruama region, in Rio de Janeiro State, Brazil. The clays used in this study were collected in the same region. The elemental chemical composition were determined in ceramic and clay samples by INAA allowing the simultaneous determination of twenty five elements, most of them at trace level. The studies of classification and provenience were made by multivariate statistical methods. The Euclidean distance and the hierarchical means in the Ward subroutine were used in cluster analysis. besides, dilution effect was also taken into account to verify the relation between clays and the different groups defined. The results of the cluster analysis and of the average dilution factor calculated for each one of the clays in relation to each group defined show that ceramics without decorations from Sao Jose have a closer chemical composition collected at the closest point at Morro Grande, denominated as Corrego Cambuci. The elements Co, Cr, Hf, Ta, Ti and Sb show smaller concentration in the ceramic, suggesting that in some way those elements are lost during fabrication or probably are diluted by the addition of temper or other materials.

    Breast cancer resistance protein (BCRP) is a member of the ATP-binding cassette (ABC) transporter superfamily. BCRP confers drug resistance in cancer by transporting chemotherapeutic agents such as mitoxantrone, topotecan, and methotrexate. Although a recent study demonstrated that wild type p53 (wt-p53) may suppress BCRP expression through the nuclear factor-KB (NF-kB) pathway in breast cancer cell line MCF-7, which expresses wt-p53 at low level, the detailed molecular mechanisms of transcriptional regulation on BCRP remain unclear. Here, we set out to reveal the exogenous p53's role on the expression of BCRP. In the human osteosarcoma cell line Saos-2, a p53-null cell line, transient transfection assays showed that the BCRP expression was activated by wt-p53 but not p53 mutants, p53R175H and p53R248W. We further co-transfected the p53 expression plasmid with BCRP luciferasepromoter reporter construct into the Saos-2 cell, and the results revealed that wt-p53 may facilitate the BCRP promoter activity. However, we did not find any p53 binding site by applying Matlnspector. Strikingly, NF-kB activity inhibition downplayed the activation effect of BCRP promoter activity by wt-p53. These results suggested that transcriptional activation of BCRP by wt-p53 is NF-kB- dependent.%乳腺癌耐药蛋白(breast cancer resistance protein,BCRP)是ATP结合盒转运蛋白超家族成员之一,其通过主动外排化疗药物如米托蒽醌、托泊替康和甲氨蝶呤,进而介导肿瘤化疗耐受.最近有研究发现,在野生型p53 (wild type p53,wt-p53)低表达的乳腺癌细胞系MCF-7中,外源性wt-p53通过抑制核转录因子-κB (nuclear factor-κB,NF-κB)的活性进而抑制BCRP的表达,但其详细的分子机制有待进一步阐明.本研究选用p53缺失的骨肉瘤细胞系Saos-2,通过瞬时转染技术发现,wt-p53可以激活BCRP的表达,而突变型p53的激活作用消失;报告基因试验显示,wt-p53可以上调BCRP启动子活性;通过生

    The aim of this paper is to assess the stages of rehabilitation of a degraded site by erosion, in Salina/Sacavém district, São Luís City, considering geomorphologic characteristics and soil bioengineering techniques. This technique has been applied in different situations to rehabilitate degraded areas, with positive results from the use of biodegradable materials (e.g. vegetal fibres, wooden stakes and re-vegetation). These techniques stabilize the soil at low cost and improve the environment. Bioengineering involves the planned and strategic application of selected materials, involving biodegradable materials, often in combination with 'hard engineering' structures constructed from stone, concrete and steel. The settlement of São Luís was established in 1612 and has evolved in distinct phases. Rapid urban growth was associated with industrialization in the second half of the 18th Century. Rapid population and urban growth has intensified problems, compounded by poor planning and improper soil use. São Luís, like many other Brazilian cities, has experienced rapid population growth in recent decades, which has created a series of socio-economic and environmental problems, including accelerated soil erosion. Sacavém is one of these communities where natural and human factors contribute to the severe gully erosion. The local lithology is mainly Tertiary sandstones and, to a lesser extent, shales, argillites and siltstones, all of which belong to the Barreiras Formation. Weathering on these rocks produces erodible soils, including lithosols, latosols, concretionary red/yellow clay soils and concretionary plinthosols. Thus, erodible soils and regolith are subject to high erosion rates, especially on steeper slopes subject to additional human interventions. Furthermore, although regional slopes are quite gentle, there is localized high relative relief. Sacavém vegetation, in the gullied area, consists of brushwood. Secondary mixed forest and brushwood are the

    Full Text Available Dados termopluviométricos são utilizados em diversos estudos. Contudo, a escassez de dados resultante da baixa densidade de estações meteorológicas é um problema frequentemente encontrado. Com isto, a utilização de dados estimados por satélites tem-se mostrado importante para regiões nas quais eles são escassos. Neste trabalho foram realizadas comparações entre dados mensais de precipitação pluvial estimados pelo satélite TRMM e de temperatura, estimados pelo satélite Aqua/MODIS aos dados observados por estações de superfície, para diferentes localidades do Estado de São Paulo, no período de 2003 a 2010. Os resultados demonstraram que para os dados de precipitação pluvial os menores erros foram observados nos meses de inverno e os maiores nos meses de verão. Em relação aos dados de temperatura observou-se que, com a inclusão de um fator de correção, os dados do satélite Aqua apresentaram boa exatidão em todos os meses. De maneira geral, os resultados obtidos indicam que os satélites TRMM e Aqua são alternativas eficientes na aquisição de informações em locais onde há falhas ou escassez dos mesmos podendo ser também utilizados na análise da consistência de dados coletados por meio de redes meteorológicas.Temperature and rainfall data are used in several scientific studies.

  20. Evaluation of underground water contamination of tubular wells, by fuels oil in Santo Andre City, Sao Paulo state: a contribution to the environmental management

    International Nuclear Information System (INIS)

    The contamination of underground waters by hydrocarbons originated from gas stations has been object of increasing preoccupation in environmental organization all over the world. The organic compounds Benzene, Toluene, Ethylbenzene and Xylene (BTEX), present in these fuels, are extremely toxic to human health and could make impracticable the exploration of these contaminated waters by these kinds of pollutants and consequently the gasoline wells used for this purpose. In this work, it was carried out a diagnosis of the water quality with information and analyses, with the goals to snap shot the situation of the wells destined to domestic and commercial supply of water in the urban area of Santo Andre city, Sao Paulo state. There have been evaluated the presence of micron pollutants BTEX, after contamination due to leaks in fuel storage tanks close to the wells, in different places of the city. The physical chemistry parameters like color, turbidity and residual chlorine were also evaluated as well as trace elements, metals, anions like fluorine, sulphates, chlorine, nitrates and phosphates and bacteriological (total coliforms, thermo stable coliforms, heterotrophic bacteria). On definition of the sampling area, it was sought, at first, the evaluation of environmental contaminations historical series by gas stations, evaluating the set of information available at government environmental organizations and spatial representatively of the problem. For administration of the underground water quality it was adopted the methodology used by Companhia de Tecnologia de Saneamento Ambiental (CETESB), being accomplished a previous identification of contaminated potential areas and organizing a data base on landfills disposal and neglected places; registration of gas station services and, wells used by the population, industrial inventory with active and neglected maps taking into consideration the size and residues generation (such as SEMASA), prioritizing in this way the

    Full Text Available BACKGROUND: The results of previous studies elsewhere have indicated that GB virus C (GBV-C infection is frequent in patients infected with the human immunodeficiency virus type 1 (HIV-1 due to similar transmission routes of both viruses. The aim of this study was to determine the prevalence, incidence density and genotypic characteristics of GBV-C in this population. METHODOLOGY/PRINCIPAL FINDINGS: The study population included 233 patients from a cohort primarily comprised of homosexual men recently infected with HIV-1 in São Paulo, Brazil. The presence of GBV-C RNA was determined in plasma samples by reverse transcriptase-nested polymerase chain reaction and quantified by real-time PCR. GBV-C genotypes were determined by direct sequencing. HIV viral load, CD4+ T lymphocyte and CD8+ T lymphocyte count were also tested in all patients. The overall prevalence of GBV-C infection was 0.23 (95% CI: 0.18 to 0.29 in the study group. There was no significant difference between patients with and without GBV-C infection and Glycoprotein E2 antibody presence regarding age, sex, HIV-1 viral load, CD4+ and CD8+T cell counts and treatment with antiretroviral drugs. An inverse correlation was observed between GBV-C and HIV-1 loads at enrollment and after one year. Also, a positive but not significant correlation was observed between GBV-C load and CD4+ T lymphocyte. Phylogenetic analysis of the GBV-C isolates revealed the presence of genotype 1 and genotype 2, these sub classified into subtype 2a and 2b. CONCLUSION/SIGNIFICANCE: GBV-C infection is common in recently HIV -1 infected patients in Sao Paulo, Brazil and the predominant genotype is 2b. This study provides the first report of the GBV-C prevalence at the time of diagnosis of HIV-1 and the incidence density of GBV-C infection in one year.

  2. Urbanism and energy in developing regions

    The pace of urbanization must continue, because in most parts of the world the surplus population in the countryside has nowhere else to go. The world is about 40% urban now and apparently headed for the 80 to 90% share of the total population presently exhibited by the developed countries. Thus, the 1.6 billion urban dwellers in 1978 would become about 3 billion in 1995--if major catastrophes can be avoided. Feasibility assessments for Sao Paulo-Rio de Janeiro, Calcutta, Cairo-Alexandria, Mexico City, and Seoul are presented in the appendices. This analysis-from-a-distance is insufficient to judge how much extra installed electrical generating capacity is required before 1995, the added refining capability for liquid fuels, or the uses for new LNG and coal imports due to be arranged. It is evident that energy (and perhaps also water in most regions) planning is the major determinant of the manner in which these urban areas will adapt to the extraordinary pressures for new settlement. The current round of planning in such metropolitan areas has been addressed to solving traffic-congestion problems, and reorganizing land use in central districts, as the most-pressing issues. Since energy sources and distribution systems now affect the largest and most crucial investments in urban growth it is to be expected that future metropolitan planning may concentrate upon energy efficiency. Energy supplies must be planned to meet requirements set by locally dominant values regarding human services and the environment.

    The present paper examines the validity of the application of a distributed rainfall-runoff-erosion model on a regional basis in a semi-arid region of Brazil.The model tested is known as WESP (Water Erosion Simulation Program) developed by Lopes (1987).The model simulates the hydrograph and the sedi-ment graph for individual events and thus, the model when properly calibrated can serve as a predic-tive tool for runoff and soil erosion on an individual or a continuous basis.The possibility of the exis-tence of regionally applicable values for the parameters of the model WESP would be very interesting from the point of view of predictability of runoff and soil erosion from ungauged basins in the region.For this purpose, data collected in several experimental units in the experimental basin of Sume as well as in the experimental basin of Sao Joao de Cariri have been used.The model was calibrated and validated in each of the experimental units (consisting of erosion plots and micro-basins) and the av-erage value from all of the units for each of the parameters was considered to be the regional value.With these average values, all the events in all the experimental units were simulated.The results show that the runoff and erosion values simulated with this single parameter set were very good in all the units, being well within the acceptable deviations.

    Bacterial biofilms have been identified as the primary etiological factor for the development and progression of peri-implantitis. Lasers have been shown to remove bacterial plaque from titanium surfaces effectively and can restore its biocompatibility without damaging these surfaces. Therefore, the aim of this study was to evaluate the responses (i.e., the cell viability and morphology) of human osteoblast-like SaOs-2 cells to sandblasted, large grit, and acid-etched (SLA) titanium surfaces irradiated by CO2 lasers at two different power outputs. A total of 24 SLA disks were randomly radiated by CO2 lasers at either 6 W (group 1, 12 disks) or 8 W (group 2, 12 disks). Non-irradiated disks were used as a control group (four disks). The cell viability rates of the SaOs-2 cells in the control and study groups (6 and 8 W) were 0.33 ± 0.00, 0.24 ± 0.11, and 0.2372 ± 0.09, respectively (P SLA titanium surfaces.

    Air pollution has been a serious public health problem in several countries worldwide. The development process involves the industrialization and consumption, especially electricity. In Brazil, most of this generation comes from hydroelectric dams, supplemented by thermal plants. However, the operation of fossil fuel power plants can result in the emission of air pollutants. The activity of stationary sources added to the mobile source emission (responsible for 90% of air pollution in Sao Paulo) has shown strong and serious associations with health problems. For this reason, the objective of this work was to study the effects that the operation of thermal power plant Piratininga - plant stuck in the metropolitan region in Sao Paulo state - which are essential energy for the region - has on air quality and health of the surrounding population. However, in analyzing the results it was only possible to verify a relationship between respiratory problems and the non-running of the mill. Unfortunately no evidence were found of direct interference of the plant on air quality, however, it was found that air quality in some parts of the metropolitan region in Sao Paulo state hasn't proven to be satisfactory, according to data from CETESB.

    This paper refers to the study of the bases material of the Corumbatai Formation (Parana Basin) from a clay mine, which presents limits for its use in ceramic tiles in dry grinding process due to its hardness and, especially, the high content of organic matter in relation to the clay overlaid. The characterization of the raw material and the product was accomplished by organic carbon analysis, X-ray diffraction, optical microscopy and test-firing. Firing conditions were determined to get expanded clay, using fast firing static kiln and a continuous roller kiln, both from laboratory equipment, getting samples with variable density up to the limit of expansion, with density that can reach values lower than 0,5g.cm{sup -3} because of the formation of closed pores and an external vitreous foil which provide a high mechanical resistance to the particles.

    The Gaviao Block (GB) in the northern portion of the Sao Francisco Craton-Northeast of Brazil, constitutes one of the oldest Archean fragments of the South American Platform Archean crust. GB underwent several events of juvenile accretion and reworking of continental crust along its evolutionary history, notably between the Archean and the Paleoproterozoic. {sup 207}Pb/{sup 206}Pb isotopic analyses were carried out in two zircons populations from strongly migmatized TTG terranes found in the proximity of Brumado: the first population (7 crystals) is taken as representative of the crystallization period of the TTG terranes at 3300 {+-} 45 Ma; the second (2 crystals) represents the age of the first even of metamorphism/migmatization at 2910 {+-} 10 Ma. {sup 207} Pb/{sup 206} Pb analyses in zircons from an outcrop of non-migmatized TTG in the area yielded a 3202 {+-} 15 Ma age (4 crystals), interpreted to be the crystallization period of the gneiss protolith. Sm/Nd analyses on the TTG rocks of the Brumado region yielded T{sub DM} model ages varying between 3.26 and 3.36 Ga and {epsilon}{sub Nd}{sup (t)} between -3.5 and +0.7. These data suggest the occurrence of juvenile accretions to the continental crust during the Archean, with differential involvement of crustal materials. The geochemical data of rare earth elements corresponding to the TTG terranes revealed moderate LRRE contents (La{sub N}=83,5), low HREE contents (La{sub N}=2,5) and a fairly fractionated pattern (La/Yb){sub N}=34, besides lack of negative Eu anomaly, showing that these rocks have similar compositions to those TTG terranes of cratonic continents, as well as some Archean rocks from CSF (e.g. Sete Voltas, Boa Vista). Finally, the youngest ages present in GB rocks (ca. 1.2-0.45 Ga) represent the role played by tectono thermal events, which produced partial or total rejuvenation of the Rb/Sr and K/Ar isotopic systems during the Espinhaco and Brasiliano cycles. In particular, K/Ar ages illustrate the

    International Nuclear Information System (INIS)

    This paper presents an attempt to reconstruct vegetation and climate changes in the central region of the state of Sao Paulo (Jaguariuna) and west of the state of Mato Grosso (Pontes e Lacerda) during the last 12,000 years BP, based on δ13C values of soil organic matter (SOM), 14 C dating and botanical identification of buried charcoal in the soil profiles. Sampling site in Sao Paulo was located under natural vegetation ('cerradao'), along the slope of small hills and in the top of slope under the semi-deciduous forest in Mato Grosso. Charcoal was found predominantly between 150 and 50 cm depth, indicating a period of greater frequency of fires in these regions, between 6,000 and 3,000 years BP. More enriched values of δ13C of SOM (predominance of C4 plants) were observed from approximately 12,000 to 7,000 years BP in Jaguariuna, indicating drier climate when compared with nowadays conditions. The charcoal analyses indicated the predominance of cerrado species. In Pontes e Lacerda site, the δ13C profile suggests the presence of C3 vegetation (forest) during the last 10,000 years and the most of identified charcoal fragments indicated the presence of semi-deciduous forest as well as cerrado species.

These studies had concluded to a temporary solution, which consisted in reducing loads and building additional supports. (author)

  15. Pb-Pb age and Rb-Sr and Sm-Nd isotope signature of paleoproterozoic syenitic plutonism in the south of Salvador-Curaca mobile belt: Sao Felix Syenitic Massif, Bahia-Brazil

    International Nuclear Information System (INIS)

    The Sao Felix Syenitic Massif (MSSF) has a tabular shape with about 32 km2 that represents the south expression of the aligned syenitic plutonism, which occur in the middle part of Salvador-Curaca mobile belt (CMSC). Single zircon dating by stepwise Pb evaporation methodology yields an age of 2098 ± 1 Ma to SFSM. This data correlate the emplacement of the SFSM with the late stages of SCMB stabilization. This massif is isotopically characterized by negative epsilon neodymium values (-1.45 to -2.89) and low initial strontium ratio (0.701 to 0.704). SFSM isotopic signature is similar to the ones displayed by the others syenites from the belt and reflects an enriched source which should be related to a metasomatic enriched mantle. (author)

    Isoquercitrin, a dietary phytoestrogen, is a potential stimulator of bone mineralization used for prophylaxis of osteoporotic disorders. Here we studied the combined effects of isoquercitrin, a cell membrane permeable 3-O-glucoside of quercetin, and polyphosphate [polyP], a naturally occurring inorganic polymer inducing bone formation, on mineralization of human osteoblast-like SaOS-2 cells. Both compounds isoquercitrin and polyP induce at non-toxic concentrations the mineralization process of SaOS-2 cells. Co-incubation experiments revealed that isoquercitrin (at 0.1 and 0.3μM), if given simultaneously with polyP (as Ca(2+) salt; at 3, 10, 30 and 100μM) amplifies the mineralization-enhancing effect of the inorganic polymer. The biomineralization process induced by isoquercitrin and polyP is based on two different modes of action. After incubation of the cells with isoquercitrin or polyP the expression of the Runt-related transcription factor 2 [RUNX2] is significantly upregulated. In addition, isoquercitrin causes a strong increase of the steady-state-levels of the two co-activators of RUNX2, the activating transcription factor 6 [ATF6] and the Ets oncogene homolog 1 [Ets1]. The activating effect of isoquercitrin occurs via a signal transduction pathway involving ATF6, and by that, is independent from the induction cascade initiated by polyP. This conclusion is supported by the finding that isoquercitrin upregulates the expression of the gene encoding for osteocalcin, while polyP strongly increases the expression of the Ets1 gene and of the alkaline phosphatase. We show that the two compounds, polyP and isoquercitrin, have a co-enhancing effect on bone mineral formation and in turn might be of potential therapeutic value for prevention/treatment of osteoporosis.

    Erbium:yttrium-aluminum-garnet (Er:YAG) laser treatment is an effective option for the removal of bacterial plaques. Many studies have shown that Er:YAG lasers cannot re-establish the biocompatibility of titanium surfaces. The aim of this study was to evaluate the responses of the human osteoblast-like cell line, SaOs-2, to sand-blasted and acid-etched (SLA) titanium surface irradiation using different energy settings of an Er:YAG laser by examining cell viability and morphology. Forty SLA titanium disks were irradiated with an Er:YAG laser at a pulse energy of either 60 or 100 mJ with a pulse frequency of 10 Hz under water irrigation and placed in a 24-well plate. Human osteoblast-like SaOs-2 cells were seeded onto the disks in culture media. Cells were then kept in an incubator with 5% carbon dioxide at 37 °C. Each experimental group was divided into two smaller groups to evaluate cell morphology by scanning electron microscope and cell viability using 3-4,5-dimethylthiazol 2,5-diphenyltetrazolium bromide test. In both the 60 and the 100 mJ experimental groups, spreading morphologies, with numerous cytoplasmic extensions, were observed prominently. Similarly, a majority of cells in the control group exhibited spreading morphologies with abundant cytoplasmic extensions. There were no significant differences among the laser and control groups. The highest cell viability rate was observed in the 100 mJ laser group. No significant differences were observed between the cell viability rates of the two experimental groups (p = 1.00). In contrast, the control group was characterized by a significantly lower cell viability rate (p SLA titanium surfaces. In fact, modifying SLA surfaces with Er:YAG lasers improved the biocompatibility of these surfaces.

    The contamination of underground waters by hydrocarbons originated from gas stations has been object of increasing preoccupation in environmental organization all over the world. The organic compounds Benzene, Toluene, Ethylbenzene and Xylene (BTEX), present in these fuels, are extremely toxic to human health and could make impracticable the exploration of these contaminated waters by these kinds of pollutants and consequently the gasoline wells used for this purpose. In this work, it was carried out a diagnosis of the water quality with information and analyses, with the goals to snap shot the situation of the wells destined to domestic and commercial supply of water in the urban area of Santo Andre city, Sao Paulo state. There have been evaluated the presence of micron pollutants BTEX, after contamination due to leaks in fuel storage tanks close to the wells, in different places of the city. The physical chemistry parameters like color, turbidity and residual chlorine were also evaluated as well as trace elements, metals, anions like fluorine, sulphates, chlorine, nitrates and phosphates and bacteriological (total coliforms, thermo stable coliforms, heterotrophic bacteria). On definition of the sampling area, it was sought, at first, the evaluation of environmental contaminations historical series by gas stations, evaluating the set of information available at government environmental organizations and spatial representatively of the problem. For administration of the underground water quality it was adopted the methodology used by Companhia de Tecnologia de Saneamento Ambiental (CETESB), being accomplished a previous identification of contaminated potential areas and organizing a data base on landfills disposal and neglected places; registration of gas station services and, wells used by the population, industrial inventory with active and neglected maps taking into consideration the size and residues generation (such as SEMASA), prioritizing in this way the

In this project, the distribution of natural Ra isotopes was studied in ix surface, groundwater and estuarine water samples collected from dry and wet seasons (2009 - 2010) campaigns performed in Ribeira Valley, Southern Sao Paulo State. The inventory allowed the application of Ra isotopes as tracers of fluvial and groundwater discharges to the Cananeia-Iguape estuarine complex.

The results obtained in this research work evidenced that there is a prevalence of {sup 228}Ra isotope in all the set of samples analyzed. However, the activity concentrations of Ra isotopes determined from Higher Ribeira Valley through the Southern Coastal Plain of Sao Paulo are representative of natural background levels, showing low or minimal human intervention. In the set of samples collected along Ribeira do Iguape River, Cananeia and Iguape outlets, the higher concentrations of Ra were observed in bottom waters, indicating the diffusion of {sup 228}Ra from sediments recently deposited as a potential source of the increased concentrations of this isotope when compared with others. The activity concentrations of the short-lived Ra isotopes were negligible, lower than the limit of the detection. Fluxes of Ra for Cananeia outlet are strongly influenced by tidal oscillations, which modulate the increase and decrease of Ra concentrations in response of the respective increase and decrease of waters salinity. In Iguape outlet and in hydrochemical stations performed along Ribeira do Iguape River it was observed a linear relationship between the amount of suspended matter and the increase of {sup 228}Ra activity concentration.

    Full Text Available Regional odontodysplasia (ROD is a rare developmental anomaly involving both mesodermal and ectodermal components in a group of contiguous teeth. It affects the primary and permanent dentitions in the maxilla and the mandible or both, however, the maxilla is frequently involved. Although the etiology of the ROD is uncertain, it has been suggested that numerous other factors play a role. The treatment plan should be based on the degree of involvement as well as the functional and esthetic needs in each case. This article reports the case of a 5-year-old boy presenting a rare anomaly on the right side of the maxillary arch. The treatment performed was rehabilitation with temporary partial acrylic denture and periodic checkups. The extraction was followed by rehabilitation with dental implants. The main aim of this article is to provide valuable information to pediatric dentists about the review and treatment alternatives for ROD.

    Remote sensing techniques for supporting the rural credit supervision system were developed and tested. The test area comprised the counties of Aracatuba and Guararapes, located in the State of Sao Paulo. Aerial photography, LANDSAT images and topographic charts were used. Aerial photographs were extremely useful for the out lining of properties boundaries with financing of sugarcane plantations by the Banco do Brasil S.A.. The percentage of correctly interpreted sugarcane on LANDSAT images, considering the 85 analyzed properties, was of 63.12%. The occurrence of atypical conditions such as excessive raining, sugarcane in bloom, and wind damaged sugarcane and sugarcane not harvested due to planning failures verified during the period the images were obtained, were some of the contributing factors associated with a low interpretation performance. An alternative approach was developed using several LANDSAT overpasses and auxiliary field data, which resulted in 91.77 percent correct.

    19世纪末以来,《离骚》英译本不断出现,其中以霍克斯、伯顿、宇文所安的译文影响较大。通过将宇文所安译文置于《离骚》英译史的大背景下,与霍克斯、伯顿译文的对比,来探讨其特色和成就。宇文所安的译文是民族性和世界性的辩证统一。对于独具汉民族特色的骚体,宇文所安创造性地运用“半诗体”、破折号、标点空缺以及精心选择的语词,最大限度地再现原文的文体特点,同时勾联并存了东方的哀怨美与西方的悲剧美;在陌生化内涵的翻译上,宇文所安译文体现了译者对源文化中的宗教意识和悲剧精神的深刻理解,对男女两性政治隐喻手法的准确把握。宇文所安的译文是其“世界诗歌”理念的实践,考虑到了多元语言文化的差异性、意义的开放性和传播的有效性,对中国的典籍翻译有积极的指导意义。%Since the 19th century, there have been appearing continuously translations of Li Sao. Among all the translators of this classic, David Hawkes, Burton Watson, and Stephen Owen are the most influential ones. The present essay, by comparing Stephen Owen’s version of Li Sao with the other two by David Hawkes and Burton Watson, explores Stephen Owen’s artistic achievement. Stephen Owen’s translation of Li Sao is a dialectical unity, keeping a delicate balance between nationality and universality. As for the unique genre “saoti”, Stephen Owen creatively employs“hemistiches”, dash, absence of punctuation, and delicate word selection, representing the stylistic features of the source to the most extent and combining Chinese sad sense of beauty with western tragic one. When it comes to defamiliarizing connotations, Owen’s translation reflects his deep understanding of religious and tragic conceptions embedded in the Chinese culture as well as his skillful grasp of the political connotations of love metaphors.

Because of the site of the telescope, the distances from its receivers to its digital terminals are nearly 500m. It is thus an issue to accurately transmit radio signals received by the telescope antenna. In radio astronomy it is a common practice to first convert received radio signals to proper Intermediate-Frequency ( IF) signals, and then transmit the IF signals through coaxial cables to a terminal room, where the IF signals are distributed to multiple terminals and monitoring equipments. The distribution also requires highly consistent division of single-channel signals into multi-channel signals. Meanwhile, the needed powers of signals input to different terminals are different; it will be convenient to correct for attenuations of signals input to various terminals, respectively. In this paper, we present the design and implementation of an IF-signal transmission and distribution system for the 65m radio telescope, which has a frequency range for observation of 0. 1GHz to 2. 5GHz and a channel number of 6. The signal-attenuation correction range of the system is 1dB to 30dB, and the correction can be controlled on-site or remotely. The specifications of the system, including link gains, VSWR, isolation levels, and consistency levels in distributed outputs can meet the demands. These enable the system to provide

    Dang, H.; Unger, N.

    2015-10-01

    We assess the regional and global integrated radiative forcing on 20- and 100-year time horizons caused by a one-year pulse of present day pollution emissions from 10 megacity areas: Los Angeles, Mexico City, New York City, Sao Paulo, Lagos, Cairo, New Delhi, Beijing, Shanghai and Manila. The assessment includes well-mixed greenhouse gases: carbon dioxide (CO2), nitrous oxide (N2O), methane (CH4); and short-lived climate forcers: tropospheric ozone (O3) and fine mode aerosol particles (sulfate, nitrate, black carbon, primary and secondary organic aerosol). All megacities contribute net global warming on both time horizons. Most of the 10 megacity areas exert a net negative effect on their own regional radiation budget that is 10-100 times larger in magnitude than their global radiative effects. Of the cities examined, Beijing, New Delhi, Shanghai and New York contribute most to global warming with values ranging from +0.03 to 0.05 Wm-2yr on short timescales and +0.07-0.10 Wm-2yr on long timescales. Regional net 20-year radiative effects are largest for Mexico City (-0.84 Wm-2yr) and Beijing (-0.78 Wm-2yr). Megacity reduction of non-CH4 O3 precursors to improve air quality offers zero co-benefits to global climate. Megacity reduction of aerosols to improve air quality offers co-benefits to the regional radiative budget but minimal or no co-benefits to global climate with the exception of black carbon reductions in a few cities, especially Beijing and New Delhi. Results suggest that air pollution and global climate change mitigation can be treated as separate environmental issues in policy at the megacity level with the exception of CH4 action. Individual megacity reduction of CO2 and CH4 emissions can mitigate global warming and therefore offers climate safety improvements to the entire planet.

  12. Tectonic-thermal evolution from the northeast region of Minas Gerais and South of Bahia

    International Nuclear Information System (INIS)

    The northeast region of Minas Gerais and South Bahia are centered to the east of 420 00'WGr, between parallels 150 and 180. Its tectonic-thermal evolution is presented here with the support of stratigraphy/lithology, structural analysis, petrography, petrochemistry, regional metamorphism/retro metamorphism and radio chronology. It is pointed out that the evolution occurred in a mobile belt initiating its history in the terminal Archean up to Inferior Proterozoic. The northeast of the region attained crustal stability during 1700 My up to 1800 My (Sao Francisco Craton) meanwhile the rest of the zone kept mobilized till upper proterozoic times. Radio chronological studies suggest for the post tectonic granitic rocks, ages from the brasiliano cycle as well as for those pre-existing rocks which suffered isotopic regeneration and metamorphose in that same cycle an original age from Archean to inferior proterozoic times, except for those which are situated in the northeast part of the region. Petrochemical data point to an origin from sedimentary processes for the majority of the metamorphosed rocks in this region. (author)

  13. Diagnostic nuclear medicine in Brazil: Current status in the five geographical regions

    International Nuclear Information System (INIS)

    Full text: Brazil has a population of 170 millions of inhabitants distributed into five geographical regions (North, Northeast, South, Southeast and Medium West). Health indicators like child mortality, cardiovascular and cancer mortality rates as well as life expectancy at birth have great disparities between northeast and southeast regions. In Brazil there are 215 nuclear medicine centers having 704 equipments, both public and private. More than 80% of operating equipment are in private institutions. The Southeast region constitutes about 60% of the radiopharmaceuticals consumption and the image equipment on the country. The state of Sao Paulo, located in Southeast region, has 37% of 99mTc consumption and is the only 18FDG consumer in the country. Aiming to evaluate the correlation between consumption of radiopharmaceuticals, number of equipment and frequency of procedures performed, as well as the activity administered per procedure, a national survey is going on. This includes both public and private institutions representing general and specialised public hospitals and private institutions. The preliminary results indicated that the diagnostic procedures range from 712 to 12,682 exams per year with the majority being myocardial and bone imaging. Differences were noticed in the amount of administered activities between public and private institutions both in Southeast and Northeast regions. This may be due to the differences in the availability of state of the art equipment, routine quality control and performance procedures. (author)

    This work has as its main objective the geomechanical characterization on the future rocky mass foundation of the Tijuco Alto dam, sited at the Ribeira river, in the cities of Ribeirao, Sao Paulo state and Adrianopolis, Parana state, Brazil, owned by the Companhia Brasileira de Aluminio (Brazilian company of Aluminium). To reach that target, field studies were made to qualify the geotechnical parameters of the rocky mass, in the axis area open galleries. It was also used in situ deformability and stress test results performed in those galleries, that were reinterpreted for a better adaptation of the mass values. The knowledge of the mass inherent characteristics together with the laboratories test results, allowed for the geomechanical classification applications in several different gallery sectors. The geomechanical data obtained allowed through mathematical expressions, to reach the rocky mass values correlations of interest to the work (deformability and strength), that could be compared to the in situ test results. That analysis permitted, besides the classification critical system evaluation, the geomechanical characterization of the rocky mass, focusing its ability to the dam arch construction. (author)

    We present high-resolution, H-band, imaging observations, collected with Subaru /HiCIAO, of the scattered light from the transitional disk around SAO 206462 (HD 1353448). Although previous sub-mm imagery suggested the existence of the dust-depleted cavity at r theory, and derive a disk aspect ratio of h approx. 0.1, which is consistent with previous sub-mm observations. This model can potentially give estimates of the temperature and rotation profiles of the disk based on dynamical processes. independently from sub-nun observations. It also predicts the evolution of the spiral structures, which can be observable on timescales of 10-20 years, providing conclusive tests of the model. While we cannot uniquely identify the origin of these spirals, planets embedded in the disk may be capable of exciting the observed morphology. Assuming that this is the case, we can make predictions on the locations and, possibly, the masses of the unseen planets. Such planets may be detected by future multi-wavelengths observations,

    We present high-resolution, H-band, imaging observations, collected with Subaru/HiCIAO, of the scattered light from the transitional disk around SAO 206462 (HD 135344B). Although previous sub-mm imagery suggested the existence of the dust-depleted cavity at r approximates 46 AU, our observations reveal the presence of scattered light components as close as 0".2 (approx 28 AU) from the star. Moreover, we have discovered two small-scale spiral structures lying within 0".5 (approx 70 AU). We present models for the spiral structures using the spiral density wave theory, and derive a disk aspect ratio of h approx 0.1, which is consistent with previous sub-mm observations. This model can potentially give estimates of the temperature and rotation profiles of the disk based on dynamical processes, independently from sub-mm observations.

    Total nitrogen has been determined by using a model developed between the conventional chemical measurements and diffuse reflectance spectra in the near-infrared region. Samples (244) from different types of soils with total nitrogen contents ranging from 0.20 to 13.60% (m/m) were modeled by partial least-squares regression (PLS), multi-layer perceptron feed-forward networks (MLP) and radial basis function networks (RBFN). The RBFN model produced a better square error of prediction (SEP) of 0.048 and R(2) = 0.93 in a procedure that is simpler, faster and less dependent on the initial conditions.

    The flaviviruses of major medical importance in South American countries are yellow fever, dengue, Saint Louis encephalitis, West Nile and Rocio viruses. Rocio virus (ROCV) has been responsible for epidemics of severe encephalitis in Brazil with a case-fatality rate of 10 % and development of sequelae in 20 % of the survivors. We have sequenced and characterized the entire genome of ROCV for the first time, by determining the general traits of the open reading frame and the characteristics of viral genes including the potential cleavage sites, conserved or unique motifs, cysteine residues and potential glycosylation sites. The conserved sequences in the 3'-non-coding region were identified, and the predicted secondary structures during cyclization between 5'- and 3'-non-coding regions were studied. Multiple protein and phylogenetic analyses based on antigenically important and phylogenetically informative genes confirmed a close relationship between ROCV and Ilheus virus (ILHV), together constituting a unique and distinct phylogenetic subgroup as well as the genetic relationship of ROCV with several members of the Japanese encephalitis group. Although ROCV is phylogenetically related to ILHV, our study shows that it is still a virus distinct from the latter virus. This is the first flavivirus uniquely indigenous to Brazil that has been sequenced completely and the genome characterized. The data should be useful for further studies at the molecular level, including construction of infectious clone, identification of gene function, improved disease surveillance based on molecular diagnostic tools and vaccine development.

    Santos estuary, located in Southeastern Brazilian Coast, is impacted by several anthropic activities. The largest commercial harbor in South America and the main petrochemical and metallurgical industrial centre in the country, with approximately 1100 industries, are also in this estuary. The estuarine system has an important channel, called Bertioga Channel, which connects the upper Santos estuary to the ocean. In this channel are located the main mangroves of the estuarine complex that have a great potential of heavy metals retention. This behavior is related to sedimentary dynamics of system, where contaminated sediments from upper estuary are filtrated by channel before reaching the ocean. In this context, the main goal of this work was to carry out a study on toxic elements in cores from Bertioga Channel. Enrichment Factor (EF) was determined and it was related to geochronological data, allowing the evaluation of anthropic activities impact in this region. Thus, in February 2010, were collected five cores along the channel using a vibrocorer. The cores (150 - 220 cm) were sliced at every 2 cm, the samples were frozen and freeze-drying. Elemental preparation and analysis (As, Cd, Cr, Cu, Ni, Pb, Sc and Zn) followed SW-846 methodologies applying ICP-OES technique. Geocronology was determined via gamma spectrometry, by 210Pbxs and 137Cs methods. In order to assess the degree of sediment contamination, enrichment factors (EF) were calculated using Sc as normalization element Background values correspondeded to the element concentration in the bottom sediment core as determined by 210Pb chronology. EFs obtained in all analyzed cores were lower than 2, indicating a minimal pollution for the region. However, in core Bertioga 5 (the closest one to Santos harbor), it can be seen As, Cr, Pb and Zn enrichment from the bottom to the top, mainly from 70's, when harbor activities expanded. Despite of the low levels found for the studied elements, Bertioga channel area has

  3. Assessment of micro, macro, toxic elements (Cd, Hg, Pb) and fatty acids profile in consumed fish commercially available in Cananeia and Cubatao, Sao Paulo State

    International Nuclear Information System (INIS)

    Aside from their nutritional importance, fish are considered one of the most important bio indicators in aquatic systems for the estimation of pollution levels by toxic metals. This is so, since fish can bio accumulate these elements and they occupy different trophic levels and present different sizes and age. The purpose of the present study was to contribute with important data for the knowledge of nutritional and toxic constituents in muscles of the most consumed fish species from two coastal regions, Cananeia and Cubatao. Cananeia fish species analyzed were: Micropogonias furnieri (Corvina), Macrodon ancylodon (Pescada), Centropomus undecimalis (Robalo peba) and Mugil platanus (Tainha). From Cubatao, Micropogonias furnieri (Corvina), Macrodon ancylodon (Pescada), Menticirrhus americanus (Perna de moca), Sardella braziliensis (Sardinha) and Mugil liza (Tainha). For this study, analytical methodologies were developed and validated, regarding precision and accuracy, by means of certified reference materials. Micronutrients (Ca, Fe, K, Na, Se and Zn) and some trace elements (As, Br, Co, Cr, Rb) in fish muscle were determined by means of neutron activation analysis (NAA). Cold Vapor Atomic Absorption Spectrometry (CV AAS) was used for total Hg determination and Electrothermal Atomic Absorption Spectrometry (ET AAS) for Cd and Pb determinations. Proximate composition determinations according to AOAC methodologies and fatty acids profiles by gas chromatography were done in these muscle fish samples. Regarding fatty acids profile from the ω-6 family, Tainha species pool presented the highest values (8.9%) and Pescada species pool the lowest ones (4.4%) for Cananeia species. Fatty acids from the ω-3 family, Sardinha pool species presented the highest values (31.8%) for all species analyzed. Regarding micronutrients content great concentration variations between individual of the same species and between different species were observed. Discriminate analysis was used

    The present work shows the results of provenience studies for ceramics collected at Sao Jose, Morro Grande, Serrano and Bela Vista archaeological sites in Araruama region, in Rio de Janeiro State, Brazil. The clays used in this study were collected in the same region. The elemental chemical composition were determined in ceramic and clay samples by INAA allowing the simultaneous determination of twenty five elements, most of them at trace level. The studies of classification and provenience were made by multivariate statistical methods. The Euclidean distance and the hierarchical means in the Ward subroutine were used in cluster analysis. besides, dilution effect was also taken into account to verify the relation between clays and the different groups defined. The results of the cluster analysis and of the average dilution factor calculated for each one of the clays in relation to each group defined show that ceramics without decorations from Sao Jose have a closer chemical composition collected at the closest point at Morro Grande, denominated as Corrego Cambuci. The elements Co, Cr, Hf, Ta, Ti and Sb show smaller concentration in the ceramic, suggesting that in some way those elements are lost during fabrication or probably are diluted by the addition of temper or other materials.

    The objective of the present study was to evaluate magnesium and manganese concentrations in Perna perna mussels by applying instrumental neutron activation analysis (INAA). The mussels were collected seasonally from September 2008 to July 2009 at Cocanha Beach in the city of Caraguatatuba (clean region), and at two sites in Santos Bay (Ponta de Itaipu and Palmas Island). The mussel samples were cleaned, grinded, homogenized, lyophilized and then analyzed by INAA. The INAA procedure consisted in the irradiation of the samples and synthetic elemental standards for 10 s, under a thermal neutron flux of 6.6 x 10{sup 12} n cm{sup -2} s{sup -1} in the nuclear research reactor of IPEN-CNEN/SP. The measurements of the gamma radioactivity of the samples and standards were carried out using a hyperpure semiconductor Ge detector, coupled to Digital Spectral Analyzer. The elemental concentrations were calculated by the comparative method. For quality control of analytical results, certified reference materials NIST SRM 1566b oyster tissue and NRC DORM-2 Dogfish Muscle were analyzed and their results indicated good accuracy. The element concentrations in mussels on dry mass basis varied from 2734 {+-} 205 to 5138 {+-} 507 mg kg{sup -1} for Mg and from 7.35{+-}0.57 to 29.06{+-}3.35 mg kg{sup -1} for Mn. The results obtained in mussel analysis indicated that the samples collected in Itaipu in the winter season presented higher accumulation of Mg than the other sites. For Mn, the highest concentrations were obtained for the mussels collected in Palmas in summer time. (author)

  11. Micronutrients (Ca, Fe, K, Na, Se, Zn) assessment and fatty acids profile in fish most consumed by Cubatao community, Sao Paulo, Brazil

    International Nuclear Information System (INIS)

    Fish are a healthy source of protein, providing omega-3 (n-3) the fatty acids that reduce cholesterol levels, and reduce the incidence of heart disease and stroke. The purpose of the present study was to assess the concentration of some micronutrients and also fatty acids profile in muscles of the most consumed fish species from Cubatao coastal region. Cubatao carnivorous fish species analyzed were: Micropogonias furnieri (Corvina), Macrodon ancylodon (Pescada) and Menticirrhus americanus (Perna-de-Moca), and planktivorous species Sardinella braziliensis (Sardinha) and Mugil liza (Tainha). Micronutrients (Ca, Fe, K, Na, Se, Zn) in fish muscle were determined by means of instrumental neutron activation analysis (INAA). Fatty acids profiles in these muscle fish samples were performed by gas chromatography. Total saturated fatty acids ranged from 23.0% in M. ancylodon to 50.0% in M. liza. Total polyunsaturated fatty acid contents varied from 10.9% in M. liza 38.4% in S. braziliensis. These fish species presented different proportions of polyunsaturated fatty acids of the n-3 family and of the n-6 family. Regarding the n-6 family, M. furnieri showed the highest values (13.3%) and M. ancylodon, the lowest ones (4.1%). On the other hand, for the n-3 family, S. braziliensis presented the highest value (31.8%) and M. liza the lowest one (5.7%). Regarding micronutrients content, great concentration variations between individual of the same species and between different species were observed. From the nutritional point of view S. braziliensis is the best choice showing highest content of fatty acid n-3 family and micronutrient concentrations. (author)

  12. A multiscale approach indicates a severe reduction in Atlantic Forest wetlands and highlights that Sao Paulo Marsh Antwren is on the brink of extinction.

    Full Text Available Over the last 200 years the wetlands of the Upper Tietê and Upper Paraíba do Sul basins, in the southeastern Atlantic Forest, Brazil, have been almost-completely transformed by urbanization, agriculture and mining. Endemic to these river basins, the São Paulo Marsh Antwren (Formicivora paludicola survived these impacts, but remained unknown to science until its discovery in 2005. Its population status was cause for immediate concern. In order to understand the factors imperiling the species, and provide guidelines for its conservation, we investigated both the species' distribution and the distribution of areas of suitable habitat using a multiscale approach encompassing species distribution modeling, fieldwork surveys and occupancy models. Of six species distribution models methods used (Generalized Linear Models, Generalized Additive Models, Multivariate Adaptive Regression Splines, Classification Tree Analysis, Artificial Neural Networks and Random Forest, Random Forest showed the best fit and was utilized to guide field validation. After surveying 59 sites, our results indicated that Formicivora paludicola occurred in only 13 sites, having narrow habitat specificity, and restricted habitat availability. Additionally, historic maps, distribution models and satellite imagery showed that human occupation has resulted in a loss of more than 346 km2 of suitable habitat for this species since the early twentieth century, so that it now only occupies a severely fragmented area (area of occupancy of 1.42 km2, and it should be considered Critically Endangered according to IUCN criteria. Furthermore, averaged occupancy models showed that marshes with lower cattail (Typha dominguensis densities have higher probabilities of being occupied. Thus, these areas should be prioritized in future conservation efforts to protect the species, and to restore a portion of Atlantic Forest wetlands, in times of unprecedented regional water supply problems.

    A preliminary conceptual model of groundwater flow was developed for the Serra Geral fractured basalt aquifer in order to assess the recharge to the underlying sandstone Guarani Aquifer System, one of the main aquifer systems in Brazil, which supplies water to millions of people. Detailed geological investigations included macroscopic description of the basalt flow units and the underlying sandstone. Petrographic and chemical analyzes were conducted on rock samples from outcrops and from five drilled boreholes. Detailed fracture surveys were accomplished at outcrops to characterize fracture sets and their potential to transmit water in the current tectonic context. Four basalt flows were identified in the Ribeirao Preto area and were named B1, B2, B3 and B4 (from oldest to youngest). The cooling process in flow B3 led to the generation of large sub-horizontal fractures at the contacts B2/B3 and B3-C/B3-E, which are the most transmissive structures. Groundwater flow in the basalt appears to be of the stratabound type because fractures, in general, do not propagate through the basalt vesicular layers, which behave as a regional hydraulic barrier for the vertical groundwater flow. However, it is proposed that the localized, continuous and closely spaced subvertical tectonic fractures, the only features that have the potential to crosscut the vesicular layers and the intertrappe sediments, can vertically connect the sub-horizontal transmissive fractures. Weathering and water seepage, observed in rock exposures, indicate that subvertical NE-trending fractures would be the most transmissive in the Ribeirao Preto area.

    Unique observations of the horizontal neutral winds in the altitude range 70 to 115 km have been performed from satellite platforms by HRDI and WINDII (UARS) and by TIDI (TIMED), the former since September 1991 and the latter since January 2002. All three experiments observed airglow on the terrestrial limb and derived vertical wind profiles of geophysical quantities by inverting altitude scans of Doppler shifted emission spectra. As a result, the global mesosphere / lower thermosphere region has been sampled for 14 years by a common technique resulting in an unparalleled neutral wind database. This database will be one of the key contributions to an improved Horizontal Wind Model (HWM). This paper will describe results from the first long term climatological study of the MLT region based on satellite wind measurements. The basic dynamic structure in the MLT is a tide, which also has long-term variation that has similar periods to the 27-month QBO (quasi-biennial oscillation) and the SAO (semi-annual oscillation). Signatures of ultra-long variability require analysis of the full wind database.

    This paper reports the long term observations of small and medium-scale gravity waves over Brazilian equatorial region. Coordinated optical and radio measurements were made from OLAP at Sao Joao do Cariri (7.400S, 36.500W) to investigate the occurrences and properties and to characterize the regional mesospheric gravity wave field. All-sky imager measurements were made from the site. for almost 11 consecutive years (September 2000 to November 2010). Most of the waves propagated were characterized as small-scale gravity. The characteristics of the two waves events agreed well with previous gravity wave studies from Brazil and other sites. However, significant differences in the wave propagation headings indicate dissimilar source regions. The observed medium-scale gravity wave events constitute an important new dataset to study their mesospheric properties at equatorial latitudes. These data exhibited similar propagation headings to the short period events, suggesting they originated from the same source regions. It was also observed that some of the medium-scale were capable of propagating into the lower thermosphere where they may have acted directly as seeds for the Rayleigh-Taylor instability development. The wave events were primarily generated by meteorological processes since there was no correlation between the evolution of the wave events and solar cycle F10.7.

    Aside from their nutritional importance, fish are considered one of the most important bio indicators in aquatic systems for the estimation of pollution levels by toxic metals. This is so, since fish can bio accumulate these elements and they occupy different trophic levels and present different sizes and age. The purpose of the present study was to contribute with important data for the knowledge of nutritional and toxic constituents in muscles of the most consumed fish species from two coastal regions, Cananeia and Cubatao. Cananeia fish species analyzed were: Micropogonias furnieri (Corvina), Macrodon ancylodon (Pescada), Centropomus undecimalis (Robalo peba) and Mugil platanus (Tainha). From Cubatao, Micropogonias furnieri (Corvina), Macrodon ancylodon (Pescada), Menticirrhus americanus (Perna de moca), Sardella braziliensis (Sardinha) and Mugil liza (Tainha). For this study, analytical methodologies were developed and validated, regarding precision and accuracy, by means of certified reference materials. Micronutrients (Ca, Fe, K, Na, Se and Zn) and some trace elements (As, Br, Co, Cr, Rb) in fish muscle were determined by means of neutron activation analysis (NAA). Cold Vapor Atomic Absorption Spectrometry (CV AAS) was used for total Hg determination and Electrothermal Atomic Absorption Spectrometry (ET AAS) for Cd and Pb determinations. Proximate composition determinations according to AOAC methodologies and fatty acids profiles by gas chromatography were done in these muscle fish samples. Regarding fatty acids profile from the {omega}-6 family, Tainha species pool presented the highest values (8.9%) and Pescada species pool the lowest ones (4.4%) for Cananeia species. Fatty acids from the {omega}-3 family, Sardinha pool species presented the highest values (31.8%) for all species analyzed. Regarding micronutrients content great concentration variations between individual of the same species and between different species were observed. Discriminate analysis

    Rapakivi granites and associated mafic and ultramafic rocks in the Rondonia Tin Province, southwestern Amazonian craton, Brazil were emplaced during six discrete episodes of magmatism between ca 1600 and 970 Ma. The seven rapakivi granite suites emplaced at this time were the Serra da Providencia Intrusive Suite (U-Pb ages between 1606 and 1532 Ma); Santo Antonio Intrusive Suite (U-Pb age 1406 Ma); Teotonio Intrusive Suite (U-Pb age 1387 Ma); Alto Candeias Intrusive Suite (U-Pb ages between 1346 and 1338 Ma); Sao Lourenco-Caripunas Intrusive Suite (U-Pb ages between 1314 and 1309 Ma); Santa Clara Intrusive Suite (U-Pb ages between 1082 and 1074 Ma); and Younger Granites of Rondonia (U-Pb ages between 998 and 974 Ma). The Serra da Providencia Intrusive Suite intruded the Paleoproterozoic (1.80 to 1.70 Ga) Rio Negro-Juruena crust whereas the other suites were emplaced into the 1.50 to 1.30 Ga Rondonia-San Ignacio crust. Their intrusion was contemporaneous with orogenic activity in other parts of the southwestern Amazonian craton, except for the oldest, Serra da Providencia Intrusive Suite. Orogenic events coeval with emplacement of the Serra da Providencia Intrusive Suite are not clearly recognized in the region. The Santo Antonio, Teotonio, Alto Candeias and Sao Lourenco-Caripunas Intrusive Suites are interpreted to represent extensional anorogenic magmatism associated with the terminal stages of the Rondonian-San Ignacio orogeny. At least the Sao Lourenco-Caripunas rapakivi granites and coeval intra-continental rift sedimentary rocks may, in contrast, represent the products of extensional tectonics and rifting preceding the Sunsas/Aguapei orogeny (1.25 to 1.0 Ga). The two youngest rapakivi suites, the Santa Clara Intrusive Suite and Younger Granites of Rondonia, seemingly represent inboard magmatism in the Rondonian-San Ignacio Province during a younger episode of reworking in the Rio Negro-Juruena Province during the waning stages of the collisional 1.1 to 1.0 Ga

    The assessment of the content of nutrients in musts and wine has been the subject of several studies due to its importance for the quality control and even for determining the geographical authenticity of a specific wine brand. Not less important is the assessment of the impact on the final product caused by the presence of contaminants in the soil. It has to be taken also into consideration that the addition of fertilizers, pesticides, and even irrigation water can increase the content of contaminants in the soil. Fertilizers, for example, may contain unwanted elements such as trace metals and radionuclides. These contaminants can affect both the quality and the commercial value of the agricultural products. The most important contaminants, as far as radioactive elements is concerned, are the members of the uranium and thorium natural series, and potassium-40, which is present in ali soils and rocks with an average concentration around 0.012% of the natural potassium. The content of uranium and of its decay products in soils can be modified by the addition of phosphate fertilizers. Although several studies have been performed aiming to assess the impact of the presence of metals and radionuclides in many agricultural products, there is no reference in the literature concerning the presence of natural radionuclides in grapes and wine. Therefore, this study was carried out with the objective of determining the content of some members of the uranium and thorium decay series (namely, {sup 226}Ra and {sup 228}Ra), besides {sup 40}K, in grapes and wine produced in the Fazenda Milano, in the municipality of Petrolina - Pernambuco, in the Vale do Sao Francisco.

    Currently in Canada, there is no consensus concerning the efficacy of regionalization, a reversal of the strong commitment in favour only a decade earlier. Instead, provincial governments are either dismantling regional health authorities in favour of highly centralized structures under the control of ministries of health or actively considering more centralized approaches. There is a general feeling among political leaders that regionalization has failed to achieve its original objectives. However, by not including physicians and primary care within regionalized governance, provincial governments have never given regionalization a real chance. Moreover, given the fact that the status quo prior to regionalization was far from an ideal state and would be almost impossible to return to in any event, some provincial governments should consider implementing a more full-blooded version of regionalization before abandoning the approach.

    We have investigated the region of the H2SO4/HNO3/H2O ternary liquid/solid phase diagram bounded by ice, nitric acid trihydrate (NAT), and sulfuric acid tetrahydrate (SAT) using differential scanning calorimetry (DSC) and infrared spectroscopy of thin films. We report measurements and analysis of the eutectic melting curves in the ternary system of the hydrates mentioned as well as the temperature of the eutectics: ice/SAT/NAT, ice/sulfuric acid hemihexahydrate (SAH)/NAT, and SAT/NAT. We report for the first time an analysis of the content of the solid phase of completely frozen samples and find that sulfuric acid octahydrate (SAO) is often present in frozen ternary samples and can be a significant portion of the solid phase. We provide a description of how the melting path of a frozen ternary sample can be predicted using the ternary phase diagram. We have parameterized our melting point data and provide equations to generate the ternary melting surface. Finally, we compare our results to the historic work of Carpenter & Lehrmann (Carpenter, C. D.; Lehrman, A. Trans. AIChE 1925, 17, 35) and to other more recent work.

In this report we present the dependence of the vertical and zonal components of this electric field with the solar activity, based on the solar flux F10.7. For this study we consider the geomagnetically quiet days only (Kp <= 3+). A magnetic field-aligned-integrated conductivity model was developed for proving the conductivities, using the IRI-2007, the MISIS-2000 and the IGRF-11 models as input parameters for ionosphere, neutral atmosphere and Earth magnetic field, respectively. The ion-neutron collision frequencies of all the species are combined through the momentum transfer collision frequency equation. The mean zonal component of the electric field, which normally ranged from 0.19 to 0.35 mV/m between the 8 and 18 h (LT) in the Brazilian sector, show a small dependency with the solar activity. Whereas, the mean vertical component of the electric field, which normally ranges from 4.65 to 10.12 mV/m, highlight the more pronounced dependency of the solar flux.

There follows an evaluation of the characteristics of the region and the presentation of different approaches to the region. From the classic ideas (von Humboldt, 1885, Dokuceaev, 1899, Herbertson, 1905, and others we get to a wide interpretative array of what we accept as organizational spatial units of geographical reality. The environmental region has important connotations with regard to the system as a surrounded element (man, society and the adjacent system. Critical environmental regions are areas where there already exists interactive degradation. The critical character may be physical, hence the “geocritical regions” or the result of human impact, hence the “anthropocritical regions.” Critical situations are differentiated at the local, regional, and global level. In order to understand critical regional situations we must refer to the following characteristics: fragility, resilience, and vulnerability. Still there are few environmental studies on critical regions and work must be done in this field.

    Full Text Available The reasons behind the need to prepare a law on regions are both internal and external in nature. We need regions as a second level of local government primarily to counter internal development problems and the need for decentralisation in Slovenia. Developmentaly stagnant and depressed areas account for more than 70% of Slovene territory. The share of founds earmarked directly from central government for regional promotion is falling and is lower than the average in European Union countries. Analyses of population and employment, and of the economic, infrastructure and educational capacities of the Slovene regions reveal serious regional differences. The reasons for the establishment of regions in Slovenia also lie in the diversity of regional problems, which are different in Zasavje, Pomurje, Gorenjska or Primorska. Any restriction to an administrative territorial division would blur the special regional features which, even by Europe-wide comparision, are characteristic of Slovenia. And we cannot simplify the tackling of urgent regional problems as being a matter for relations between the central government and a large number of very diverse municipalities.

RESULTADOS: Foram maiores o peso corporal, circunferência do braço, dobras cutâneas do tríceps e subescapular, resistência elétrica, escores Z da área do braço, área muscular do braço e percentual de gordura corporal no sexo feminino em relação ao masculino. Baixa estatura foi encontrada em 8% das meninas e 5,6% dos meninos, sem diferença quanto ao gênero. Houve menor prevalência de desnutrição (2% das meninas e 5,6% nos meninos, do que de sobrepeso e obesidade (30% e 11,2%, respectivamente. Observou-se anemia em 24,4% e ferropenia em 10,5% dos escolares com ou sem anemia. Apresentaram valores abaixo do limite inferior do padrão de referência para cobre e zinco séricos, respectivamente três e sete indivíduos. CONCLUSÃO: Na população estudada, de baixo nível econômico e institucionalizada, ocorre o processo de transição nutricional e alta prevalência de anemia que não resulta da interação ferro, cobre e zinco.OBJECTIVE: To assess the anthropometry, body composition and iron, copper and zinc nutritional status, according to gender, of institutionalized children and adolescents living in two shantytowns in the city of Sao Paulo. METHODS: A cross sectional study using weight, height, arm circumference, skinfolds, electrical
