    Derris urucu is an Amazonian plant with insecticide and ichthyotoxic properties. Studies with this species show the presence of flavonoids, mainly rotenoids, as well as stilbenes. The ethanol extract of the leaves of Derris urucu (Leguminosae) afforded three new dihydroflavonols named urucuol A (1), B (2) and C (3), and the dihydroflavonol isotirumalin (4). Their structures were elucidated by extensive analysis of 1D and 2D NMR, UV and IR spectra and MS data and comparison with literature data. The isolated compounds (1-4) were evaluated for DPPH radical scavenging activity and showed a relatively lower antioxidant ability compared to the commercial antioxidant trans-resveratrol. (author)

    Full Text Available In some previous studies, we described the isolation of nine compounds from leaves of Derris urucu, a species found widely in the Amazon rainforest, identified as five stilbenes and four dihydroflavonols. In this work, three of these dihydroflavonols [urucuol A (1, urucuol B (2 and isotirumalin (3] were evaluated to identify their potential as allelochemicals, and we are also reporting the isolation and structural determination of a new flavonoid [5,3′-dihydroxy-4′-methoxy-(7,6:5″,6″-2″,2″-dimethylpyranoflavanone (4]. We investigated the effects of the dihydroflavonols 1-3 on seed germination and radicle and hypocotyl growth of the weed Mimosa pudica, using solutions at 150 mg.L–1. Urucuol B, alone, was the substance with the greatest potential to inhibit seed germination (26%, while isotirumalin showed greater ability to reduce the development of the hypocotyl (25%, but none of the three substances showed the potential to inhibit radicle. When combined in pairs, the substances showed synergism for the development of root and hypocotyl and effects on seed germination that could be attributed to antagonism. When tested separately, the trend has become more intense effects on seed germination, while for the substances tested in pairs, the intensity of the effect was greater on development of weed.

    The Amazon biodiversity may provide plants whose chemical substances are capable of controlling weeds. In this study we report the isolation and identification of five stilbenes from the leaves of 'timbo vermelho' (Deguelia rufescens var. urucu): 4-methoxylonchocarpene (1); 3,5-dimethoxy-4'-hydroxy-3'-prenyl-trans-stilbene (2), lonchocarpene (3), 3,5-dimethoxy-4'-Oprenyl- trans-stilbene (4) and pterostilbene (5). Compounds 2 and 4 are new natural products although 2 has been previously cited as synthesis product. Potential allelopathic activity for 1, 2 and 4 was evaluated over seed germination and plant growth of Mimosa pudica weed. The observed effects on seed germination did not vary significantly (p > 0.05) when the analysis of phytotoxicity was performed with the substances alone, the maximum inhibition did not exceed 20%. The most intense inhibitions on radicle and hypocotyl development were found for compound 4 (p < 0.05). When tested in pairs, showed antagonism for seed germination and synergism for radicle and hypocotyl development. (author)

    Full Text Available Transformations of Derry/Londonderry’s medieval city walls during the twentieth century have shaped an urbanism of segregated settlements within a city of religious confrontation. The heritage of military blockades, peace lines and watchtowers imposed upon the city’s Walls has influenced the disintegration of public space and created areas of no man’s land around the peripheries of the monument. The aim of this paper is to examine physical transformation and trace the consequences of urban planning regarding the historic city Walls. This change includes the shifting of residential settlements in the Bogside/Fountain areas and the movement of Protestant settlements towards the Waterside of Derry/Londonderry. The history and heritage of the Walls are analysed by focusing on four periods: 1600, when the first medieval walls were constructed; the housing crisis of 1948; the 1968 urban area plan and the beginning of the ‘Troubles’; and the present day. This analysis offers an understanding of the spatial relationships between enclaves and the monument over key moments of conflict and political change. The paper reveals that the manifestations of the Walls have aided in the further division of religiously segregated communities in Derry/Londonderry.

    Palaeotropic Derris-like taxa (family Fabaceae, tribe Millettieae) comprise 6-9 genera. They are well known as important sources of rotenone toxin, which are used as organic insecticide and fish poison. However, their phylogenetic relationships and classification are still problematic due to insufficient sampling and high morphological variability. Fifty species of palaeotropic Derris-like taxa were sampled, which is more than in former studies. Three chloroplast genes (trnK-matK, trnL-F IGS, and psbA-trnH IGS) and nuclear ribosomal ITS /5.8S were analyzed using parsimony and Bayesian methods. Parsimony and Bayesian analyses of individual and combined markers show more or less similar tree topologies (only varying in terminal branches). The old-world monophyletic genera Aganope, Brachypterum, and Leptoderris are distinct from Derris s.s., and their generic status is here confirmed. Aganope may be classified into two or three subgeneric taxa. Paraderris has to be included in Derris s.s. to form a monophyletic group. The genera Philenoptera, Deguelia, and Lonchocarpus are monophyletic and distinct from each other and clearly separate from Derris s.s. Morphologically highly similar species of Derris s.s. are shown to be unrelated. Our study shows that previous infrageneric classifications of Derris are incorrect. Paraderris elliptica may contain several cryptic lineages that need further investigation. The concept of the genus Derris s.s. should be reorganized with a new generic circumscription by including Paraderris but excluding Brachypterum. Synapomorphic morphological features will be examined in future studies, and the status of the newly defined Derris and its closely related taxa will be formalized.

    The aim of this study was to reveal the pyridine metabolism in leaves of two mangrove legumes, Derris indica (= Millettia pinnata or Pongamia pinnata) and Caesalpinia crista. Radioactivity from [carbonyl-14C]nicotinamide supplied exogenously to young leaf disks was recovered in nicotinic acid, nicotinic acid mononucleotide, NAD, NADP, nicotinamide mononucleotide and trigonelline. These mangrove species, especially D. indica, have strong ability to convert nicotinamide to trigonelline, but not to nicotinic acid glucoside. The endogenous trigonelline content in leaves of D. indica was more than 830 microg/g dry weight. This value is 5-12 times greater than that in leaves of Glycine max. There was little short-term effect of 250 and 500 mM NaCl (equivalent to ca. 50% and 100% sea water) on nicotinamide metabolism.

    Full Text Available The rivers and floodplain lakes of the Urucu petroleum-bearing region in central Amazonia are extensively colonized by aquatic macrophytes, which may be affected by accidental spills during oil extraction and transportation operations. Among the species of macrophytes, the free-floating Eichhornia crassipes (water hyacinth is abundant; AIM: The objective of this study was to evaluate the effect of different dosages of Urucu crude oil (0, 0.5, 1.5 and 3.0 L.m-2 on the biomass of E. crassipes and on some physical and chemical characteristics of the water in which the plant grew; METHODS: The experiment was conducted over a period of 84 days. Every seven days, the biomass (live and dead of E. crassipes and the temperature, pH, electrical conductivity and dissolved oxygen in the water were measured; RESULTS: The dosage of 0.5 L.m-2 was sufficient to cause partial mortality (48% in E. crassipes after 35 days of exposure to oil. The dosage of 3.0 L.m-2 caused total mortality (100% in E. crassipes after 84 days of exposure. The decomposition of the oil and the dead biomass of E. crassipes reduced the dissolved oxygen and pH, and increased electrical conductivity and concentrations of total phosphorus in the water; CONCLUSIONS: We conclude that an oil spill can cause total mortality in the local population of one macrophyte species, but not of another. This may alter the macrophyte species diversity in the impacted region. In the case of E. crassipes and Pistia stratiotes, an Urucu crude oil spill could favor E. crassipes, the species less sensitive to oil.Os rios e lagos de várzea da província petrolífera de Urucu, na Amazônia Central, são amplamente colonizados por macrófitas aquáticas, que podem ser afetadas por acidentes durante a exploração e o transporte de petróleo.

    The usage of taking of digital aerial images is a reality worldwide, but in Brazil there is few sensors in use available, which makes recognize the pioneer aspect of the technique. Something similar also occurs with the airborne LASER scanning, whose technique has been applied for more time, used in the obtaining of digital terrain models. The use of digital imaging along with the LASER survey can offer an option for the generation of high quality products in a very fast and efficient way, aiming at numberless applications. Among such applications, the generation of cartographic products for the implantation of pipelines, as well as the as-built drawings of these same rights-of-ways after the implantation can be highlighted. The pipeline sector has been the focus of great investments and keeps on presenting demand for new projects and implantations. That allows to deduce that the speed in the generation of accurate bases for such purpose shall progress towards the continuous development of such aerial survey techniques. This paper presents the application of images and LASER survey to obtain ortho photos of Urucu-Coari liquefied petroleum gas (LPG) pipeline. (author)

    This work, aims to sharpen the main difficulties of acting in SMS and the corrective and preventive measures in the work of the pipeline Urucu / Manaus, located in the influence of the Solimoes River, covering several municipalities in the state of Amazonas (Coari, Codajas, Caapiranga, Anama, Iranduba, Manaus). Such pipeline has three spread, namely Spread A, from Urucu to Coari, Spread B1, from Coari to Anama, and Spread B2, from Anama to Manaus. For the purpose of the present case, we have focused on the Spread B2, from the city of Anama to Manaus, from km 475 to Km 662, being 174,400 m long. Its main line ends right within the premises of the Refinaria Isaac Sabba (a local refinery), which is located at Rua Rio Quixito - Distrito Industrial. The purpose of the pipeline is to convey natural gas to the Pressure Regulating Station, which is located close by the aforementioned refinery. The gas is transported to Maua Thermoelectrical, to generate energy for certain areas of the Amazon capital city. The information has been obtained through observations made on the difficulties faced by the workers to comply with safety behaviour while carrying out their activities. Also, by using several tools, such us Auditoria Comportamental (Behaviour Auditing) - Audicomp, Aplicacao de Listas de Verificacao - LV's (Verification Lists), as well as Indice de Praticas Seguras - IPS (Safety Practices Index). The collected data is analysed, and displayed in graphics, tables and processed in PETROBRAS internal systems, such Audicomp (Behaviour Auditing), SALV (Verification Lists Application System), and Auditoria de IPS (Safety Practices Index Auditing). The main difficulties to implement SMS (Safety, Environment and Health) in a pipeline works in the Amazon require from the transportation logistics, communication problems, lack of enough local skilled labor, the adverse region's season conditions, both flood and dry seasons, as well as to commit the local population with

    Petroleum plant activities in the Amazon result in a series of negative impacts on the natural resources. The formation water, a secondary product of oil production, carries high salt levels and its environmental release results in salinization of several water bodies in the Amazon. The effect of formation water on vegetal and animal physiology is unknown. This paper estimated the effects of formation water from the Urucu petroleum plant at different dilutions on the haematocrit, hemoglobin concentration, red blood cell counts, mean corpuscular volume, mean hemoglobin concentration, mean corpuscular hemoglobin concentration, blood oxygen content, partial pressure of oxygen, glucose and lactate levels, plasma and intra erythrocytic levels of Na{sup +}, K{sup +} and Ca{sup 2+}, Phe and p Hi of Colossoma macropomum (Branchial breather) and Glyptoperichthys joselimaianus (facultative air breather). To maintain tissue oxygen supply the studied species adjusted several of these parameters. Cell swelling, high lactate levels, decrease in p He and p Hi have been observed in G. joselimaianus exposed to formation water. The decrease in p Hi result in a decrease of Hb-O{sub 2} affinity in the erythrocytes. On the other hand, an increase in p He and p Hi were observed in C. macropomum. Significant changes in ionic content, in particular plasma and erythrocytic levels of sodium, have been observed for both species exposed to formation water. A decrease of plasma potassium was observed in G. joselimaianus. The intra erythrocytic levels of calcium increased in Colossoma and Glyptoperichthys but no significant change in plasma levels of calcium was observed. The disturbance in blood ion levels resulted in a decreased of blood oxygen content. Colossoma seems to better buffer the effects of formation water exposure than Glyptoperichthys. (author)

    Full Text Available Rotenone is one of the prominent insecticidal isoflavonoid compounds which can be isolated from the extract of Derris sp. plant. Despite being an effective compound in exterminating pests in a minute concentration, procuring a significant amount of rotenone in the extracts for commercialized biopesticides purposes is a challenge to be attained. Therefore, the objective of this study was to determine the best ionic liquid (IL which gives the highest yield of rotenone. The normal soaking extraction (NSE method was carried out for 24 hrs using five different types of binary solvent systems comprising a combination of acetone and five respective ionic liquids (ILs of (1 [BMIM] Cl; (2 [BMIM] OAc; (3 [BMIM] NTf2; (4 [BMIM] OTf; and (5 [BMPy] Cl. Next, the yield of rotenone, % (w/w, and its concentration (mg/mL in dried roots were quantitatively determined by means of RP-HPLC and TLC. The results showed that a binary solvent system of [BMIM] OTf + acetone was the best solvent system combination as compared to other solvent systems (P<0.05. It contributed to the highest rotenone content of 2.69 ± 0.21% (w/w (4.04 ± 0.34 mg/mL at 14 hrs of exhaustive extraction time. In conclusion, a combination of the ILs with a selective organic solvent has been proven to increase a significant amount of bioactive constituents in the phytochemical extraction process.

    The incidence and mortality of sepsis and severe sepsis in hospitalised patients is seasonal and consistently highest during the winter. The primary aim of this study was to measure the seasonal variation in the prevalence of emergency department (ED) patients with sepsis. This cross-sectional study was performed over two four-week periods in the summer and in the winter, respectively. The clinical records of all patients presenting to the ED during the study periods were retrospectively screened to determine if they met the criteria for “uncomplicated” sepsis and severe sepsis or septic shock. The prevalence of “uncomplicated” sepsis was higher in the winter (43.9 per 1000) compared to the summer (30.7 per 1000). The prevalence of severe sepsis or septic shock was also higher in the winter (17.7 per 1000) compared to the summer (11.7 per 1000). This quantitatively demonstrates the increased ED burden of sepsis in the winter that can be used to inform healthcare planning and resource allocation.

    This paper presents the historical evolution of the activity of equipment inspection of the PETROBRAS/UN-BSOL, in which the developments of a motivation program of the personnel from the effort developed for the certification of inspectors since the techniques more known most modern for the examination of installations and equipment was of great importance. PETROBRAS was introduced in the ACFM by TSC-Technical Software Consultants, during NDT (Non Destructive Test) Congress in 1994. PETROBRAS/UN-BSOL was the first unit to acquire the last equipment, called Amigo. In 2002 has qualified three professionals to ACFM level I. Nowadays, five inspectors level I and one level II and the technique has been used through inspections in several equipment with very well satisfactory. The Duto de Coleta de oleo de LUC de 10in and the Duto de Coleta de gas de LUC de 14in had been inspected with the PIG using the technique of Magnetic flux leakage (MFL), being that in the first one it was used Quantitative Smart PIG (High Resolution) and in as it was used Qualitative Smart PIG (Low Resolution). The results show that, despite the raised cost of the High Resolution PIG, this still is indicated for in-line inspection of pipelines of the UN-BSOL. (author)

    The Amazon Forest plays a major role in C sequestration and release. However, few regional estimates of soil organic carbon (SOC) stock in this ecoregion exist. One of the barriers to improve SOC estimates is the lack of recent soil data at high spatial resolution, which hampers the application of new methods for mapping SOC stock. The aims of this work were: (i) to quantify SOC stock under undisturbed vegetation for the 0–30 and the 0–100 cm under Amazon Forest; (ii) to correlate the SOC stock with soil mapping units and relief attributes and (iii) to evaluate three geostatistical techniques to generate maps of SOC stock (ordinary, isotopic and heterotopic cokriging). The study site is located in the Central region of Amazon State, Brazil. The soil survey covered the study site that has an area of 80 km{sup 2} and resulted in a 1:10,000 soil map. It consisted of 315 field observations (96 complete soil profiles and 219 boreholes). SOC stock was calculated by summing C stocks by horizon, determined as a product of BD, SOC and the horizon thickness. For each one of the 315 soil observations, relief attributes were derived from a topographic map to understand SOC dynamics. The SOC stocks across 30 and 100 cm soil depth were 3.28 and 7.32 kg C m{sup −2}, respectively, which is, 34 and 16%, lower than other studies. The SOC stock is higher in soils developed in relief forms exhibiting well-drained soils, which are covered by Upland Dense Tropical Rainforest. Only SOC stock in the upper 100 cm exhibited spatial dependence allowing the generation of spatial variability maps based on spatial (co)-regionalization. The CTI was inversely correlated with SOC stock and was the only auxiliary variable feasible to be used in cokriging interpolation. The heterotopic cokriging presented the best performance for mapping SOC stock. - Highlights: • The SOC stocks across 30 and 100 cm depth were 3.28 and 7.32 kg C m{sup −2}, respectively. • SOC stocks were 34 and 16%, respectively, lower than those observed in other studies. • Regions with waterlogging soils presented the lowest SOC stock. • Heterotopic cokriging, using CTI, improved the accuracy of SOC stock maps.

    Our purpose is to focus on the Safety, Environment and Health (SEH) Management, integrated to pipeline construction and assembly, aiming at minimizing the risks involving the transportation and handling of 20-inch pipes. Please note that peculiar, challenging situations occur when constructing a gas pipeline at the Coari-Anama Section, which leads to some difficulty in the exploitation of oil and gas, where fragile elements represented by the environment and man are faced in this evolution and progress process. Overcoming the severe conditions while streaming 196.6-km-length of pipes in flooded lands no doubt represented a real challenge. State-of-the-art techniques have been implemented such as air transportation of pipes, with two large-sized helicopters being used (Kamov and S64 Skycrane). This has demanded integrated actions to be adopted, involving transportation of concrete pipes, double joints, pipesak, hydraulic excavators, net carrier containing assorted materials, skids and natural gas pressure, measurement and filtering equipment. Nevertheless, we have succeeded in reducing the rate of exposure to the construction and assembly process risks, thus minimizing occurrences and improving the conditions of processes, where, had the conventional method been used, would have led to a great amount of incidents and accidents, resulting mainly from the huge logistic difficulties, which would expose the task force to high potential risks.

Constatou-se que a maior taxa de frutificação (48,3 % ± 3,2 ocorreu via polinização livre, onde os insetos não foram excluídos. Foi verificada a ocorrência de autopolinização, porém com taxa inferior de frutificação (12,2% ± 4,9. A anemofilia não foi constatada na espécie. A avaliação da produção de néctar em Rubus sp. resultou em valores compatíveis com a síndrome de melitofilia. Os visitantes florais coletados e observados sobre as flores de Rubus sp. foram predominantemente abelhas da ordem Hymenoptera (97%, que iniciam, em menor número, a atividade de forrageamento às 8h, com pico de atividade às 12h e declinando até às 16h. As coletas resultaram numa amostragem de 1.360 abelhas, divididas em quatro famílias e 13 espécies. A família com maior riqueza de espécies (N = 7 foi Halictidae e a mais abundante foi Apidae, com 1.288 indivíduos. Em Apidae, houve o predomínio da espécie exótica Apis mellifera, cuja representação na amostra foi de 1.246 indivíduos. Os dados da abundância e as observações naturalísticas do seu comportamento da flor apontaram A. mellifera como o principal polinizador de Rubus sp., mas confirmam que as demais espécies de abelhas também participam na polinização de Rubus sp.The pollination ecology of the blackberry (Rubus sp. was studied by means of determining its reproductive system, the analysis of flower's nectar production. Sampling the insects that visit the flower of blackberry in a cultivated area and analysis of pollination behavior. The experiments were carried out in an area of blackberry crop, in December of 2005 in the city of Timbó (SC, Southern Brazil. The highest fruit set (48.3% ± 3,2 occurred in the free pollination (natural treatment where insects were not excluded. The occurrence of selfing was verified, however with o lower fruit set (12.2% ± 4,9. Anemophily was not observed in the species. The nectar evaluation in Rubus sp. resulted in values compatible with the melit tophily syndrome. Bees (Hymenoptera were the main floral visitors collected and observed on the flowers of Rubus sp., representing 97% of the individuals. They initiate the foraging activity at 8 a.m., with a peak activity at 12 a.m. and declining until 4 p.m. in the survey were sampled 1.360 bees, belonging to four families and 13 species. Halictidae was the family with highest amount of species (N = 7 and Apidae most abundant (1.288 individuals in the survey. Apidae was mainly represented by Apis mellifera, which is a exotic species, whose sample was of 1.246 individuals. The data of the abundance and the observation of its behavior, pointed A. mellifera as the main pollinator of Rubus sp, in the studied area, but also confirms that the other native species of bees, participate in the pollination process of Rubus sp.

    The goal is to show the monitoring systems and deadline control, using the PMBOK{sup R} project management tools, in the Construction and Assembly of the Coari-Manaus Gas-pipeline, stretch B1, which includes the cities of Coari, Codajas, Anori and Anama, in the state of Amazon, in the Northern Undertaking Implementation (IENOR), an Engineering division of the PETROBRAS System. This report presents the practical effects of the usage of three schedule control tools of the project: Performance Measurement, using the technique of the Earned Value Management (EVM), which integrates cost, schedule and physical progress of the enterprise to determine the variations of schedule and performance; Project Management Software, MSProject, which allows schedule's elaboration and makes the tracking of the planned dates possible (baseline) in relation to real dates and forecasts the trend level, the effects of changes in the project's schedule, demonstrating its utility as a schedule control tool; and Schedule Variance Analysis, which adopts practical data to reach the pessimistic, most likely and optimistic expectations. The implantation of these tools was based in the Work Breakdown Structure of the enterprise. The application of these three tools in the tracking and control of the enterprise demonstrates that, the use of information and techniques deriving from the planning and control can be an important support for project management and decision taking, comparing the results gotten in the implantation of the plan with its actual realization, defining, thus, the necessary corrective actions, generating learned lessons to use in future projects.

    Bio-pesticides are becoming increasingly important as pest management tools in various cropping systems in the tropics essentially to remedy problems associated with the indiscriminate use of hard and non-environmental friendly inorganic pesticide. In these past few decades, many bio-pesticidal products, both microbial-based (bacteria, fungi, microsprodia, entomopathogenic nematodes and viruses) and plant-based botanicals (rotenone and azadiracthin) have been studied for their use against insect pests in the tropics. In this study, the effects of the concentration process with respect to the yield of rotenone (mg) and its concentration (mg/mL) are presented extensively. The raw plants were collected from Kota Johor Lama, Johor and sorted to obtain the roots and stems. Only the roots and stems were utilized as raw materials of the extraction process. The rotenone from roots and stems was extracted using the normal soaking extraction (NSE) at 28 to 30 degree Celsius with 95 % (v/v) of acetone as a solvent and the solvent-to-solid ratio of 10 mL/ g. The extraction was carried out for 24 h. Next, the liquid crude extract was concentrated using the rotary evaporator at 50 degree Celsius and 80 mbar of vacuum pressure to remove approximately 90 % of solvent. The fractions of the liquid crude extract were collected (15 min/ mL/ fraction), diluted (1/100 with acetone) and cleaned up (to remove any fine debris) prior to determination of rotenone content (mg) and concentration (mg/mL) by using the reverse-phase high performance liquid chromatography (RP-HPLC). Finally, the results showed that there was a significant effect of thermal degradation or dissipation of rotenone content at higher operating temperature (greater than 40 degree Celsius) with a rapid rotenone reduction for the first 15 min of exposure. The possibilities for better exploitation and identification of the effective operating parameters based on the above mentioned results will be perhaps discussed in the future. (author)

    The Diabetes Early Readmission Risk Indicator (DERRI ™ ) was previously developed and internally validated as a tool to predict the risk of all-cause readmission within 30 days of discharge (30-d readmission) of hospitalized patients with diabetes. In this study, the predictive performance of the DERRI ™ with and without additional predictors was assessed in an external sample. We conducted a retrospective cohort study of adult patients with diabetes discharged from 2 academic medical centers between 1/1/2000 and 12/31/2014. We applied the previously developed DERRI ™ , which includes admission laboratory results, sociodemographics, a diagnosis of certain comorbidities, and recent discharge information, and evaluated the effect of adding metabolic indicators on predictive performance using multivariable logistic regression. Total cholesterol and A1c were selected based on clinical relevance and univariate association with 30-d readmission. Among 105,974 discharges, 19,032 (18.0%) were followed by 30-d readmission for any cause. The DERRI ™ had a C-statistic of 0.634 for 30-d readmission. Total cholesterol (TC) was the lipid parameter most strongly associated with 30-d readmission. The DERRI ™ predictors, A1c, and TC were significantly associated with 30-d readmission; however, their addition to the DERRI ™ did not significantly change model performance (C-statistic 0.643 [95% CI, 0.638-0.647], p=0.92). Performance of the DERRI ™ in this external cohort was modest but comparable to other readmission prediction models. Addition of A1c and TC to the DERRI ™ did not significantly improve performance. Although the DERRI ™ may be useful to direct resources toward diabetes patients at higher risk, better prediction is needed. DERRI = Diabetes Early Readmission Risk Indicator; TC = Total cholesterol; A1c = hemoglobin A1c; HDL-C = high-density lipoprotein cholesterol; LDL-C = low-density lipoprotein cholesterol; DKA = diabetic ketoacidosis; HHS

    The innumerable logistical problems encountered during the implementation of the gas pipeline Urucu - Coari - Manaus, located in the Amazon forest, connecting the Base Operations Geologist Pedro de Moura in Urucu to the refinery Isaac Sabba - Reman, in the city of Manaus, contributed considerably for PETROBRAS to seek non conventional solutions in the construction and assembly of pipelines in our country. Among these solutions, there is the technique of distributing pipes through cargo helicopters. The need for the usage of this technique, innovative in Brazil, comes from the lack and/or insufficiency of land access from Solimoes River to the gas pipeline main route, and the large quantities of flooded areas and/or flood plain, and also the type of soil, that together with the high index of rainfall in the region, makes the soil fully inappropriate to the traffic of heavy equipment.

  20. Petrobras eyes LNG project in Amazon region

    1995-01-01

    The Brazilian state oil company has proved gas reserves in the Rio Urucu area of the Amazon jungle totaling 1.84 tcf. That compares with 3.08 tcf contained in the offshore Campos basin, source of most of Brazil's oil and gas production. The environmentally sensitive Urucu region is one of the most dense, remote jungles in the world. Because of environmental concerns about pipelines in the rain forest and a government emphasis on boosting the natural gas share of Brazil's energy mix, a small liquefied natural gas project is shaping up as the best option for developing and marketing Urucu gas. The amazon campaign underscores a government initiative to boost Brazilian consumption of natural gas. In Brazil natural gas accounts for only 4% of primary energy consumption. Some years ago, the government set an official goal of boosting the gas share of the primary energy mix to 10% by 2000. The paper discusses current drilling activities, gas production and processing, the logistics of the upper Amazon, and gas markets

The application of these lines of direction gave support to the implantation of essential activities, such as a fishery of changes, the recovery of sanded small rivers, prevention of spills and the opening of chances for research in that further and little known basin of the Urucu River. The convergence was that PETROBRAS made use of the logistic that the scientists needed; and they made use of the knowledge that the company needed. It was just necessary to adjust the language.

    An inventory of the amphibians of the Reserva Ecológica Michelin - REM in southern Bahia, Brazil is presented. Sixty-nine species were recorded during a ten-year sampling period. Amphibians were distributed in two orders (Gymnophiona and Anura), belonging to twelve families [Aromobatidae (1), Bufonidae (3), Centrolenidae (1), Craugastoridae (5), Eleutherodactylidae (3), Hemiphractidae (2), Hylidae (34), Phyllomedusidae (5) Leptodactylidae (7), Microhylidae (4), Odontophrynidae (3) and Caeciliidae (1)]. Fifty per cent of the reproductive modes known for Atlantic forest anurans were recorded. While no threatened species were found at REM, six species are classified as data deficient (DD) by the Brazilian Red List of threatened species and deserve additional attention. Phasmahyla timbo and Vitreorana eurygnatha are listed as endangered in Bahia according to the list of threatened species of the state. Despite a higher diversity of amphibians in the Atlantic forest having been reported for mountainous regions, our results revealed that amphibian richness for lowland forests is also high.

The treatments consisted of 50 common bean genotypes and two standard plant species, efficient or inefficient in P uptake. The results were assessed through correlation and cluster analysis (multivariate). Sangue de Boi, Rosinha, Thayu, Grafite, Horizonte, Pioneiro and Jalo Precoce common bean genotypes were the most efficient on P uptake, and Carioca 80, CNF 10, Perola, IAPAR 31, Roxao EEP, Apore, Pioneiro, Pontal, Timbo and Ruda were the most efficient in P utilization. The P derived from seed influences the identification of common bean genotypes for P uptake efficiency. (author)

    The challenge of constructing the gas pipeline Urucu-Coari-Manaus, which has 662 kilometers of extension, from the Base of Operations Geologist Peter de Moura, in Urucu, to the Isaac Sabba Refinery - REMAN, in the city of Manaus, challenged PETROBRAS to search for innovative solutions in the construction of terrestrial ducts in Brazil. The introduction of these solutions was made necessary in view of, mainly, great difficulties of logistic imposed by the Amazonian forest, place where the enterprise in question was implemented. Of the new used techniques, the air transportation of pipes by cargo helicopters, the assembly of columns on pontoon ferries, opening ditches using excavators placed on 'H' shaped pontoon ferries and welding tie-in joints on a system of floating porches (pontoon ferries), must be emphasized. This work will be dedicated specifically to non-conventional constructive methods employed to overcome the construction difficulties due to the instability of the ground of flooded areas in the Amazonian forest, which during 6 (six) months of the year are total and/or partially submerged.

    In the heart of the Amazon forest, some 600 km from the city of Manaus, the Brazilian Oil Company - PETROBRAS - is developing the 'URUCU PROJECT'. Consisting on 3 oil and gas production fields and 3 natural gas processing plant, 2 huge pipelines crossing the dense Amazon forest and its rivers and going towards COARI - the Fluvial Terminal of Solimoes river. Then, vessels and ferries, loads LGN to the north region and oil to feed the Manaus refinery plant. In a near future natural gas pipelines will connect COARI to Manaus and URUCU to Porto Velho. The whole project will allow energy supply to the less developed and isolated region of Brazil, and brings relief for the local population, but represents one of the biggest challenges for the oil and gas industry in terms of environmental sustainability for projects in very sensitive areas. The paper concludes that it is viable to face such a challenges counting on an Environmental Management System tailored to fit the region peculiarities, including a high level of Preparedness and Response for oil incidents, and last but never least assuming a respectful attitude towards the Amazon and its people.

    In Brazil, the deforestation, pollution, losses in historic and cultural patrimony are each time more common in communities which, due to the great distances from urban centers, lack of any level of information. Normally, in these communities, theaters do not exist, nor local cinemas or places where people can have access to any type of art and culture. In this context, the Amazon suffers from the same problems than other regions in Brazil, however allied to logistic difficulties and other local specificities. That way, this work is about an experience lived in the Urucu-Coari-Manaus gas pipeline construction and assembly process, in which 18 communities were involved in a work of Environmental Education through arts: music, theater, movies, and others. In those communities there is great disinformation or distortion regarding programs and environmental plans from Urucu-Coari-Manaus gas pipeline, mainly due to the distance from urban centers and lack of communication vehicles. But this initiative did not come from an obligation or legal recommendations, but from a necessity to reach this public using an assertive communication. This work's specific goals were: To use the interpenetration between art and education and the playful, creative and humorous language of specific artistic interventions, adjusted to that public and its peculiarities, in order to lead the dialogue between different knowledge, that is, between traditional culture and environmental concepts paved in studies and scientific data, and to spread Urucu-Manaus gas pipeline environmental programs; To arise, in the artistic interventions, that specific public's participation and integration, always focusing the environmental message and the respect for the Amazonian culture; To value, in all artistic interventions, people's traditional knowledge, the Amazonian environment and, mainly, the importance of each local inhabitant for that environment's conservation, important for us all

    Full Text Available Rotenone is a biopesticide with an amazing effect on aquatic life and insect pests. In Asia, it can be isolated from Derris species roots (Derris elliptica and Derris malaccensis. The previous study revealed the comparable efficiency of alcohol-based deep eutectic solvent (DES in extracting a high yield of rotenone (isoflavonoid to binary ionic liquid solvent system ([BMIM]OTf and organic solvent (acetone. Therefore, this study intends to analyze the optimum parameters (solvent ratio, extraction time, and agitation rate in extracting the highest yield of rotenone extract at a much lower cost and in a more environmental friendly method by using response surface methodology (RSM based on central composite rotatable design (CCRD. By using RSM, linear polynomial equations were obtained for predicting the concentration and yield of rotenone extracted. The verification experiment confirmed the validity of both of the predicted models. The results revealed that the optimum conditions for solvent ratio, extraction time, and agitation rate were 2 : 8 (DES : acetonitrile, 19.34 hours, and 199.32 rpm, respectively. At the optimum condition of the rotenone extraction process using DES binary solvent system, this resulted in a 3.5-fold increase in a rotenone concentration of 0.49 ± 0.07 mg/ml and yield of 0.35 ± 0.06 (%, w/w as compared to the control extract (acetonitrile only. In fact, the rotenone concentration and yield were significantly influenced by binary solvent ratio and extraction time (P<0.05 but not by means of agitation rate. For that reason, the optimal extraction condition using alcohol-based deep eutectic solvent (DES as a green additive in the extraction medium cocktail has increased the potential of enhancing the rotenone concentration and yield extracted.

    This work presents a passive constituents transport simulation in Solimoes river, that is part of Piatam Project modeling activities. The fluvial hydraulic was done using the Princeton Ocean Model (POM) for the Solimoes Terminal (TESOL) proximity region. An ADCP section was used as initial condition in one of the model boundaries. The velocity field was compared with five ADCP section collected along the simulated river and similar velocity magnitude was observed. Then this dynamic field was used to initialize the oil transport model NICOIL, the one that was used to simulate a 1000 m{sup 3} of soft oil spill (42 deg API), the Urucu type oil. Simultaneously to the ADCP data collection an in situ observation has been done to observe the oil spill spreading, using popcorn liberated in the river. The popcorn spill trajectory observed was similar to the one modeled. (author)

    The development of drilling techniques closely follows the difficulties of operating well events at low costs. In the Amazon Region, problems such as logistic support at high costs did not allow for the use of air drilling techniques as a means of obtaining the results necessary to the development of the field. Without these, there was no justification for promoting initial investments in air drilling equipment. After the Urucu/AM roads were completed, we were able to bring equipment to the area of operation. This equipment was tested in two wells, one directional and one vertical. In this paper, we describe the pioneer use of air drilling in their region and present the results obtained through it as well as the problems encountered and the techniques used to solve them.

    A depth-of-processing incidental recall paradigm, previously used as a measure of negative self-schema in depressed patients (Derry & Kuiper, 1981), was administered to normal subjects in whom depressed or neutral mood had been induced. Subjects in whom depressed mood was induced showed a pattern of recall similar to that previously found for depressed patients, suggesting (1) that at least some of the effects observed in depressed patients were a function of transient mood state, rather than persistent characteristics, and (2) that these effects of depressed mood also occur in individuals who have not been selected for vulnerability to clinical depression.

    Full Text Available An inventory of the amphibians of the Reserva Ecológica Michelin – REM in southern Bahia, Brazil is presented. Sixty-nine species were recorded during a ten-year sampling period. Amphibians were distributed in two orders (Gymnophiona and Anura, belonging to twelve families [Aromobatidae (1, Bufonidae (3, Centrolenidae (1, Craugastoridae (5, Eleutherodactylidae (3, Hemiphractidae (2, Hylidae (34, Phyllomedusidae (5 Leptodactylidae (7, Microhylidae (4, Odontophrynidae (3 and Caeciliidae (1]. Fifty per cent of the reproductive modes known for Atlantic forest anurans were recorded. While no threatened species were found at REM, six species are classified as data deficient (DD by the Brazilian Red List of threatened species and deserve additional attention. Phasmahyla timbo and Vitreorana eurygnatha are listed as endangered in Bahia according to the list of threatened species of the state. Despite a higher diversity of amphibians in the Atlantic forest having been reported for mountainous regions, our results revealed that amphibian richness for lowland forests is also high.

    To develop and validate a tool that predicts 30d readmission risk of patients with diabetes hospitalized for cardiovascular disease (CVD), the Diabetes Early Readmission Risk Indicator-CVD (DERRI-CVD™). A cohort of 8189 discharges was retrospectively selected from electronic records of adult patients with diabetes hospitalized for CVD. Discharges of 60% of the patients (n=4950) were randomly selected as a training sample and the remaining 40% (n=3219) were the validation sample. Statistically significant predictors of all-cause 30d readmission risk were identified by multivariable logistic regression modeling: education level, employment status, living within 5miles of the hospital, pre-admission diabetes therapy, macrovascular complications, admission serum creatinine and albumin levels, having a hospital discharge within 90days pre-admission, and a psychiatric diagnosis. Model discrimination and calibration were good (C-statistic 0.71). Performance in the validation sample was comparable. Predicted 30d readmission risk was similar in the training and validation samples (38.6% and 35.1% in the highest quintiles). The DERRI-CVD™ may be a valid tool to predict all-cause 30d readmission risk of patients with diabetes hospitalized for CVD. Identifying high-risk patients may encourage the use of interventions targeting those at greatest risk, potentially leading to better outcomes and lower healthcare costs.

    The purpose of this study was to describe the effects of lower limb positioning and shoe conditions on stability levels of selected single leg ballet poses performed in demi-pointe position. Fourteen female non-professional ballet dancers (mean age of 18.4±2.8 years and mean body mass index of 21.5±2.8kg/m(2)) who had practiced ballet for at least seven years, without any musculoskeletal impairment volunteered to participate in this study. A capacitive pressure platform allowed for the assessment of center of pressure variables related to the execution of three single leg ballet poses in demi pointé position: attitude devant, attitude derriére, and attitude a la second. Peak pressures, contact areas, COP oscillation areas, anterior-posterior and medio-lateral COP oscillations and velocities were compared between two shoe conditions (barefoot versus slippers) and among the different poses. Barefoot performances produced more stable poses with significantly higher plantar contact areas, smaller COP oscillation areas and smaller anterior-posterior COP oscillations. COP oscillation areas, anterior-posterior COP oscillations and medio-lateral COP velocities indicated that attitude a la second is the least challenging and attitude derriére the most challenging pose.

    Purpose: While environmental risks associated with petroleum extraction such as oil spills or leaks are relatively well known, little attention has been given to the impacts of silt. The increase in petroleum exploitation in Amazonia has resulted in sediment input to aquatic systems, with impacts on their biodiversity. Here we use a combination of field measurements and statistical analyses to evaluate the impacts of anthropogenic silt derived from the construction of roads, borrow pits, and wells during the terrestrial development of gas and oil, on macroinvertebrate communities in streams of the Urucu Petroleum Province in the Central Brazilian Amazon. Material and methods: Ten impacted and nine non-impacted streams were sampled in January, April, and November of 2007. Macroinvertebrates were sampled along a 100-m continuous reach in each stream at 10-m intervals using a dip net. Abiotic variables including, a siltation index (SI), suspended inorganic sediment (SIS), sediment color index (SCI), suspend organic sediment (SOS), pH, electrical conductivity, dissolved oxygen, temperature, water velocity, channel width, and depth, were measured at three equidistant points in each stream ({proportional_to}30-m intervals). Results and discussion: SI did not differ between impacted and undisturbed streams. SIS was higher and SCI lower (more reddish) in impacted than in non-impacted streams. SCI had a positive and SIS a negative effect on both macroinvertebrate richness and density. SIS and SCI also influenced macrophyte taxonomic composition. In impacted streams, taxonomic richness and density were 1.5 times lower than in non-impacted streams. No taxon was significantly associated with impacted streams. SIS was positively correlated with SOS and electrical conductivity while SCI was negatively correlated with SOS, electrical conductivity, and pH. The lack of difference in SI between impacted and nonimpacted streams suggests that anthropogenic sediment does not accumulate

    The goal of this project was to provide an opportunity for high school students to participate in university-level research projects. In this case, students from Pinkerton Academy (Derry, New Hampshire) were invited to participate in efforts to catalog data from the COMPTEL experiment on NASA's Compton Gamma-Ray Observatory (CGRO). These activities were part of a senior level honors course at Pinkerton. Although the success of this particular program was rather limited, we feel that the general concept is a sound one. In principle, the concept of partnerships between local schools and university researchers is one that could be especially attractive to soft money researchers. Programs can be carefully designed to benefit both the students and the research program.

    Le milieu associatif est connu en France pour son dynamisme et sa réactivité. Il en va de même en archéologie, notamment dans le domaine de la médiation. Si le public ignore bien souvent qu’une association se cache derrière le lieu qu’il vient de visiter, nombreux sont les sites archéologiques, toutes périodes confondues, dont la mise en valeur est entièrement assumée par une telle structure. Dans ce cadre, tout est envisageable, de la simple ouverture pendant les Journées européennes du patr...

    2015-12-01

    Full Text Available ABSTRACTSome ichthyotoxic plants are study object aiming to discover promising substances in the field of Biotechnology, in search of plant extracts which can be used or even transformed into natural insecticides. This paper presents a bibliographical survey in order to check the traditional use of ichthyotoxic plants as bioinsecticide. Among the plants identified as ichthyotoxic, the most cited in traditional use are those from the genera Derris, Serjania, Lonchocarpus, Magonia, and Tephrosia. The survey suggests that ichthyotoxic plant extracts can contain classes of chemical compounds such as isoflavonoids and tannins with a bioinsecticidal effect and, thus, they can be used in Biotechnology, contributing to reduce the use of synthetic insecticides that present a high toxicity level.

    This work presents the Agenda 21 Local construction process developed by PETROBRAS within the context of the 'De Olho no Ambiente' Program. This is an alternative for the sustainable development of reduced social inclusion communities located in the Company's areas of influence in the Amazon Region. Agenda 21 is a participative process that analyzes a country, state, municipal or community's actual situation, and plans its sustainable future. Its objective is to reach a new development paradigm, through the construction of an action plan focused on a future scenario desired by the local community, which takes into consideration the vulnerability and potential analysis of its socio-economical, cultural and environmental bases. PETROBRAS has introduced Agenda 21 Local in three riverside communities located in the Coari municipal, where the Solimoes Terminal (TESOL) is situated. This terminal receives and stores petroleum and gas from the Urucu Petroliferous Province, in the Amazonian State. In each location partnerships were signed with several governmental and civilian institutions during the implementation of the Agenda 21 Local Forum. Here each participant has the right to debate, which makes this a participative management process mechanism and an act of citizenship. (author)

    This work has as objective to evidence one of the consequences of most satisfactory results, talking about attendance to the legal requirements of health on a pipeline undertake at the Amazon: a positive result of index zero of malaria cases until the present days. This work, in its peak, reached the contingent of eight thousand workers lodged in rafts, boats, carps and jungle camps. To reach this index, a methodology of prevention through an entomo epidemiological control was adopted, recommended for the World-wide Organization of Health, as basic activity for malaria control in endemic areas, as in Amazon. The activities had consisted to identify the epidemiologic profile of each area, to elaborate procedures of vectorial control, to implant laboratories for analysis of malaria blades, to enable staff to accomplishment of vectorial control, to realize thermo nebulization and domestic spread and to sensitize the workers of prevention and control measures. Therefore, by means of accomplishment of these basic actions, it was possible to assure an integral, equitable and qualitative attendance providing a critical and conscientious vision of involved and the success of the procedures adopted by PETROBRAS, represented by ENGENHARIA/IENOR (Northern Undertake Implementation), unit responsible for the pipeline Urucu-Manaus Construction.

    Interest in Natural Gas in Brazil emerged in the second half of the twentieth century, against a background in which the global giants of the petroleum and gas industries stated that reserves within the country were not commercially viable. This scenario changed with the discovery of numerous oil and gas fields and resulted in the participation of numerous foreign companies bidding for exploration and production rights in the new fields established by ANP. Natural Gas has come to assume a new dimension with further recent discoveries in Santos, Espirito Santo, Sergipe and Urucu, with proven reserves in the order of 490 billion m3. This new dimension is reinforced by PETROBRAS's current strategic plan which considers investments in the order of 3.5 Billion U$ dollars for the production, processing and transport of Natural Gas and half a billion dollars for thermoelectric power stations. The use of Natural Gas in industries, in general, and in the generation of electricity will provide a strong push for the country's economy, substituting other sources of energy with the recognized advantages for production and reduced environmental impact. In this new era 24 gas distribution companies, widely distributed throughout Brazil, are also programming new investments to make best the use of Natural Gas for industry, commerce, for the residential sector and throughout all the national territory.

    Oil and natural gas are exhaustible resources. Thus, exploitation of these energy sources can lead to shortages and even the absence for future generations. In this context, royalties are included as a way to financially compensate future generations through a monthly payment made by the explorer. In Brazil, the control of the royalties and their distribution is charge of the National Agency of Petroleum, Natural Gas and Biofuels (ANP). Its function is to establish reference prices used for the payment of royalties on oil and natural gas. In this study, three methods were used to calculate royalties, using data from Leste do Urucu field, located in Solimoes Basin. The first one is imposed by Resolution ANP No. 40/2009 that uses the calculation of the reference price of natural gas produced in Brazil. The second one is an alternative method of calculating royalties produced by Bispo, 2011, considering the different compositions of the gas produced and injected. And finally, the Resolution ANP RD No. 983/2011 that uses the calculation of the price of gas injected, considering this as the price of gas processed. When performing the calculation of royalties through the proposed methodologies by Bispo, 2011, and the ANP (Resolution No. 40/2009 and RD 983/2011), the results were similar to each other, and the methodology proposed by Resolution No. 40/2009 was the most different from the others.

    The level of association between dipterans of the families Calliphoridae and Sarcophagidae and habitats with different levels of vegetation cover was analyzed at Porto Urucu in Coari, Amazonas, Brazil, with the aim of identifying the potential of these taxa as bioindicators for the assessment of forest regeneration and conservation. The flies were collected in 16 sample areas, 12 of which were clearings at different stages of regeneration (C1--early regeneration; C2--moderate regeneration; and C3--advanced regeneration) and 4 in continuous forest (F). According to the IndVal analysis, nine sarcophagid species--Peckia (Sarcodexia) lambens (Wiedemann), Peckia (Peckia) chrysostoma (Wiedemann), Peckia (Squamatodes) ingens (Walker), Sarcofahrtiopsis cuneata (Townsend), Oxysarcodexia thornax (Walker), Peckia (Euboettcheria) collusor (Curran & Walley), Oxysarcodexia fringidea (Curran & Walley), Oxysarcodexia amorosa (Schiner), and Helicobia pilifera (Lopes)--were associated indiscriminately with clearings (C1 + C2 + C3). In contrast, only one calliphorid species Chrysomya albiceps (Wiedemann) was associated with clearings in the early moderate regeneration (C1 + C2) phases, and four calliphorids were associated with continuous forest or mature clearings (C3 + F): Mesembrinella bicolor (F.), Eumesembrinella randa (Walker), Mesembrinella bellardiana (Aldrich), and Lucilia eximia (Wiedemann). These results indicate that sarcophagids may be useful for evaluating the degree of anthropogenic impact but are not suitable for the detection of minor variations in forest cover. In contrast, calliphorids may be appropriate for the evaluation of both anthropogenic impacts and the degree of forest regeneration and conservation. © The Author 2014.

    Full Text Available After World War II, nations began to worry about socio-environmental issues due to the drastic situation of pollution, deforestation and poverty that the world was in. The United Nations Conference on the Human Environment (Stockholm 72 and the United Nations Conference on Environment and Development (RIO 92 represented this concern of the countries in proposing solutions to these problems. Agenda 21, subscribed in the latter by 179 countries, portrayed the responsibility of these nations to enable sustainable economic development through social and environmental actions. These agreements are subject to application by the State, together with Non-Governmental Organizations (NGOs and private companies. Therefore, the Brazilian State has made feasible the Brazilian Agenda 21, which aims to promote economic development, reconciling environmental conservation and social justice. Coari having great importance Geopolitical, since it holds significant reserves of oil, entered in the plans of Sustainable Development of the Brazilian State. From that, Petrobras together with the city council promoted the Agenda 21 community in seven communities of Coari: Lauro Sodré, Urucu, Nova Esperança, União, Pera, Vila Lira, Santa Luzia do Bucuizinho. So it developed social projects, being: Riverside Commerce of the Citizenship and Solidary II, Production of Fish Fry of Amazonian Fishes: Generation of Income and Sustainability of the Productive Chain in Aquaculture. Thus, guided by the principles of the National Agenda 21 and from this, by carrying out with Petrobras and its onlays, socio-environmental policies in a way that promotes sustainable development and social justice. However, these social development policies in the region do not address the real adversities of the communities, such as access to electricity, water supply and leisure areas, demonstrating that financial transfers seem to be underutilized.

    Due to the growing relevance of safety and environmental protection policies in PETROBRAS and its subsidiaries, as well as official regulatory agencies and population requirements, integrity management of oil and gas pipelines became a priority activity in TRANSPETRO, involving several sectors of the company's Support Management Department. Inspection activities using intelligent PIGs, field correlations and replacement of pipeline segments are known as high cost operations and request complex logistics. Thus, it is imperative the adoption of management tools that optimize the available resources. This study presents Monte Carlo simulation method as an additional tool for evaluation and management of pipeline structural integrity. The method consists in foreseeing future physical conditions of most significant defects found in intelligent PIG In Line Inspections based on a probabilistic approach. Through Monte Carlo simulation, probability functions of failure for each defect are produced, helping managers to decide which repairs should be executed in order to reach the desired or accepted risk level. The case that illustrates this study refers to the reconditioning of ORSOL 14'' (35,56 mm) pipeline. This pipeline was constructed to transfer petroleum from Urucu's production fields to Solimoes port, in Coari, city in Brazilian Amazon Region. The result of this analysis indicated critical points for repair, in addition to the results obtained by the conventional evaluation (deterministic ASME B-31G method). Due to the difficulties to mobilize staff and execute necessary repairs in remote areas like Amazon forest, the probabilistic tool was extremely useful, improving pipeline integrity level and avoiding future additional costs.

The collected samples were analyzed for fungal growth. The results revealed that, the main moulds observed in the ruminant feeds were Penicillium spp., Aspergillus (A flavus, Cladosporium spp., Mucor spp., Trichoderma spp., A. niger, Alternaria spp., Rhizopus spp., Fusarium spp., A. fumigates and A. terreus. In addition, the winter season was of higher incidence for moulds isolation than summer season. The most toxigenic aflatoxins secreted by Aspergillus flavus include Aflatoxin B1, Aflatoxin B2, Aflatoxin G1 and Aflatoxin G2. The results of biological treatment of Aflatoxins using Saccharomyces (S cerevisiae, showed that, the addition of Saccharomyces cerevisiae at a level of (1 × 106 cfu.ml−1 and (1 × 109 cfu.ml−1 decreased the level of concentration of aflatoxin B1, B2, G1 and G2 and the level of (1 × 109 cfu.ml−1 was more efficient in reducing aflatoxins than the lower concentration.

    Full Text Available Rotenone, isolated from roots of derris plant, has been shown to possess various biological activities, which lead to attempting to develop a potent drug against several diseases. However, recent studies have demonstrated that rotenone has the potential to induce several adverse effects such as a neurodegenerative disease. Radiolytic transformation of the rotenone with gamma-irradiation created a new product, named rotenoisin B. The present work was designed to investigate the anticancer activity of rotenoisin B with low toxicity and its molecular mechanism in hepatic cancer cells compared to a parent compound, rotenone. Our results showed rotenoisin B inhibited hepatic cancer cells’ proliferation in a dose dependent manner and increased in apoptotic cells. Interestingly, rotenoisin B showed low toxic effects on normal cells compared to rotenone. Mitochondrial transmembrane potential has been decreased, which leads to cytochrome c release. Down regulation of anti-apoptotic Bcl-2 levels as well as the up regulation of proapoptotic Bax levels were observed. The cleaved PARP (poly ADP-ribose polymerase level increased as well. Moreover, phosphorylation of extracellular signal regulated kinase (ERK and p38 slightly up regulated and intracellular reactive oxygen species (ROS increased as well as cell cycle arrest predominantly at the G2/M phase observed. These results suggest that rotenoisin B might be a potent anticancer candidate similar to rotenone in hepatic cancer cells with low toxicity to normal cells even at high concentrations compared to rotenone.

    Full Text Available The economic exploitation of hydrocarbons at the Petroliferous Province of Urucu, located at 280 kilometers from the center of Coari/AM municipality, occurs inside in one of the planet’s most environmentally sensitive areas, the Amazon forest. The municipality of Coari/AM, due to economic exploration in its territory, is experimenting significative transformations in the use of its soil. The objective of this research was to diagnose, from the point of view of sustainable development, the institutional and political contextof how this economic exploration is happening, starting in 1987 up to today. Furthermore, it also has the objective of analyzing the main transformations in the use of the soil. The methodology, regardingthe spatial variation of the soil use, employed techniques of geoprocessing and of processing of digital images taken from orbital remote sensors, encompassing a 17-year period of imaging in the study area. The study also analyzed social, economic and political indicators, as well as data obtained during the field trips and interviews with the main stakeholders. The methodology developed prospective, tendentialinertial and normatives scenarios, related to the exploitation of hydrocarbons. The results obtained with the application of the proposed methodology led to the conclusion that there is significant environmental damage, resulting from the activities of hydrocarbons exploitation as well as the human expansion in the urban areas of the municipality. Moreover, the hydrocarbons exploitation almost doubled the population of the municipality in 16-year period, taking a severe toll in the municipality infra-structure and the quality of local life. Moreover, this expansion process still continues. The stakeholders, endowed with decision power, have not created mechanisms to guarantee intergeneration justice to the population of Coari, its major social actor, using the criterion of proximity of the undertaking.

    PETROBRAS (the Brazilian national oil company) built a pipeline to transport crude oil from the Urucu River region to a terminal in the vicinities of Coari, a city located in the right margin of the Solimoes River. The oil is then shipped by tankers to another terminal in Manaus, capital city of the Amazonas state. At the city of Coari, changes in water level between dry and wet seasons reach up to 14 meters. This strong seasonal character of the Amazonian climate gives rise to four distinct scenarios in the annual hydrological cycle: low water, high water, receding water, and rising water. These scenarios constitute the main reference for the definition of oil spill response planning in the region, since flooded forests and flooded vegetation are the most sensitive fluvial environments to oil spills. This study focuses on improving information about oil spill environmental sensitivity in Western Amazon by using 3D visualization techniques to help the analysis and interpretation of remote sensing and digital topographic data, as follows: (a) 1995 low flood and 1996 high flood JERS-1 SAR mosaics, band LHH, 100m pixel; (b) 2000 low flood and 2001 high flood RADARSAT-1 W1 images, band CHH, 30m pixel; (c) 2002 high flood airborne SAR images from the SIVAM project (System for Surveillance of the Amazon), band LHH, 3m pixel and band XHH, 6m pixel; (d) GTOPO30 digital elevation model, 30' resolution; (e) Digital elevation model derived from topographic information acquired during seismic surveys, 25m resolution; (f) panoramic views obtained from low altitude helicopter flights. The methodology applied includes image processing, cartographic conversion and generation of value-added product using 3D visualization. A semivariogram textural classification was applied to the SAR images in order to identify areas of flooded forest and flooded vegetation. The digital elevation models were color shaded to highlight subtle topographic features. Both datasets were then converted to

    Over geologic timescales, the exchange of organic carbon (OC) between the atmosphere, biosphere and geosphere is thought to be a major control on atmospheric carbon dioxide (CO2) concentrations, and hence global climate. The carbon fluxes from the oxidation of rock-derived OC (a CO2 source) and erosion and transport of biospheric OC (a potential CO2 sink) during fluvial transit are approximately the same order of magnitude or larger than those from silicate weathering (France-Lanord and Derry, 1997; Bouchez et al., 2010). Despite field data showing oxidation of OC moving downstream in lowland rivers, it is unclear if losses occur primarily during active fluvial transport within the river, where OC is in continual motion within an aerated environment, or during longer periods when OC is temporarily stored in river floodplains which may be anoxic. This represents a major knowledge gap, as the unknown location of OC oxidation (i.e., river vs. floodplain) limits our ability to develop process-based models that can be employed to predict OC losses, constrain carbon budgets, and unravel links between climate, tectonics, and erosion. To fill this gap, we investigated the potential for OC oxidation in both controlled laboratory experiments and a simplified field setting. We consider both rock-derived and biospheric OC. Our experiments simulated fluvial transport without floodplain storage, allowing mixtures of OC-rich and siliciclastic sediment to be transported for distances of 1000 km in annular flumes while making time-series measurements of OC concentration in both the solid (POC) and dissolved (DOC) loads, as well as measurements of rhenium concentration, which serves as a proxy for the oxidation of rock-derived OC. These transport experiments were compared to static, control experiments where water and sediment in the same proportion were placed in still water. Initial results for transport of OC-rich soil show similar behavior between the transport and static

  1. Alcohol based-deep eutectic solvent (DES) as an alternative green additive to increase rotenone yield

    Energy Technology Data Exchange (ETDEWEB)

    Deep eutectic solvents (DESs) are basically molten salts that interact by forming hydrogen bonds between two added components at a ratio where eutectic point reaches a melting point lower than that of each individual component. Their remarkable physicochemical properties (similar to ionic liquids) with remarkable green properties, low cost and easy handling make them a growing interest in many fields of research. Therefore, the objective of pursuing this study is to analyze the potential of alcohol-based DES as an extraction medium for rotenone extraction from Derris elliptica roots. DES was prepared by a combination of choline chloride, ChCl and 1, 4-butanediol at a ratio of 1/5. The structure of elucidation of DES was analyzed using FTIR, {sup 1}H-NMR and {sup 13}C-NMR. Normal soaking extraction (NSE) method was carried out for 14 hours using seven different types of solvent systems of (1) acetone; (2) methanol; (3) acetonitrile; (4) DES; (5) DES + methanol; (6) DES + acetonitrile; and (7) [BMIM] OTf + acetone. Next, the yield of rotenone, % (w/w), and its concentration (mg/ml) in dried roots were quantitatively determined by means of RP-HPLC. The results showed that a binary solvent system of [BMIM] OTf + acetone and DES + acetonitrile was the best solvent system combination as compared to other solvent systems. It contributed to the highest rotenone content of 0.84 ± 0.05% (w/w) (1.09 ± 0.06 mg/ml) and 0.84 ± 0.02% (w/w) (1.03 ± 0.01 mg/ml) after 14 hours of exhaustive extraction time. In conclusion, a combination of the DES with a selective organic solvent has been proven to have a similar potential and efficiency as of ILs in extracting bioactive constituents in the phytochemical extraction process.

    Full Text Available Tea is a popular beverage made from the leaves of evergreen shrub or tree Camellia sinensis, under the family Theaceae. Tea plant is subjected to the attack of insects, mites, nematodes and some plant pathogenic diseases. Tea production is greatly hindered due to thesemaladies. About 10-15% crop loss occurred by these pests per annum. In severe cases, it would be 100%. To combat these problems different groups of pesticides have been used in the tea fields since 1960. As tea is a consumable commodity, the effect of residue of pesticides in made tea is harmful to human health. In this context, biopesticides are being considered as environmentally safe, selective, biodegradable, economical and renewable alternatives for use in IPM programmes. Biopesticides are natural plant products and may be grown by the planters with minimum cost and extracted by indigenous methods.Biopesticides are secondary metabolites, which include alkaloids, terpenoids, phenolics, and minor secondary chemicals. It is estimated that as many as 2121 plant species have been reported to posses’ pest control properties. Botanicals like neem, ghora-neem, mahogoni,karanja, adathoda, sweet flag, tobacco, derris, annona, smart weed, bar weed, datura, calotropis, bidens, lantana, chrysanthemum, artemisia, marigold, clerodendrum, wild sunflower and many others may be grown by planters with minimum expense and extracted by indigenous methods. These botanical materials can be used as an alternative to chemical pesticides. These botanical extracts will help in controlling major pests of tea such as Helopeltis, red spider mite, aphids, thrips, jassid, flushworm, termites, nematodes etc. Thepresent note reviews the information of most widely available indigenous plants that may be used for the control of insect pests of tea as a component of IPM.

    Full Text Available As a partner in the EU co-funded 3D-ICONS project, the Discovery Programme undertook the 3D documentation of some of the most iconic cultural heritage sites in Ireland. This pan-European project aimed to establish a complete pipeline for the production of 3D replicas of archaeological monuments and historic buildings, and to publish the content to Europeana for public access. The list of Irish icons range from wider cultural landscapes to smaller ornately carved stones and includes a wide range of chronological periods: from Neolithic rock art from 2500 BC to Derry's 17th-century fortifications. The primary digitisation methods include airborne laser scanning (ALS, phase-based terrestrial laser scanning (Faro Focus 3D and close range structured light scanning (Artec EVA. These are now mainstream approaches for surveying historic landscapes, structures and objects, generating precise, high-resolution point cloud data, primarily for viewing and interaction in proprietary software applications. The challenge was to convert these complex high-volume datasets into textured 3D models, retaining the geometric integrity of the original data. The article highlights the development of a pipeline to produce a lightweight 3D model that enables the public to interact with a photorealistic model based upon accurate survey and texture data. 3D-ICONS ended in January 2015, but a new website 3dicons.ie was launched to offer continued access to the Irish 3D models and associated content and media generated during the project. The article will consider the impact of this online content, particularly how it has been used as a teaching aid in secondary schools and how this may be extended in the future. It will also demonstrate how content from the project has been remodelled to develop an interactive and immersive experience for the great mound at Knowth, a development in partnership with the operators of the Brú na Bóinne visitor centre.

    Full Text Available Le regard médiatique semble distiller une perception homogène voire standardisée du jeu sportif collectif. Cependant, derrière cette forme apparemment uniforme du jeu, s’entrevoit une diversité des regards de laquelle découle une pluralité de manières d’exprimer verbalement et corporellement le jeu sportif. En investissant le milieu du handball professionnel, notre travail méthodologique, de type herméneutique, tente d’accéder au sens que donnent les acteurs à leur pratique de prédilection au travers de leurs discours et de leurs comportements. Les résultats montrent que s’opère un véritable processus de conversion dans l’exercice du métier confrontant chacun au problème de sa propre identité professionnelle. Être joueur de handball de haut niveau, être joueur professionnel et être joueur expert d’une pratique sportive, ces trois postures se conjuguent et se situent au cœur de la définition identitaire du sportif.Media attention seems to distil a homogeneous or even standardized image of team sports. However, behind the apparent uniformity of sports, we glimpse a variety of images/portraits, from which flow many ways of verbally and corporally expressing team sports. In delving into the milieu of professional handball, our methodological work, of a hermeneutical type, tries to reach the meaning the actors give to their practice of predilection through their speech and their behaviours. The results show that a veritable process of conversion takes place in practicing the sport, confronting each of them with the problem of his own professional identity. Being a high level handball player, being a professional player and being an expert sports player, these three combined postures are at the heart of the athlete’s identity definition.

    Full Text Available Dans Les origines de la France contemporaine, Taine assimile la prise de la Bastille à l'anarchie. La foule est représentée comme un « animal primitif », affranchi de la raison et livré à ses instincts. L'historiographie jacobine de la Révolution française a depuis longtemps remis en question cette représentation animalière de la foule, en montrant que derrière les violences populaires, il existe des logiques politiques, sociales et économiques qui supposent une part de rationalité des acteurs. La violence est donc complexe, étant à la fois destructrice et fondatrice, comme le montrent les journées de juillet 1789.Cet article entend expliquer le processus par lequel la violence populaire a contribué in fine à la naissance de la nation française. L'imaginaire du complot a joué ici un rôle fondamental, qu'il s'agira de mettre en lumière en faisant une lecture croisée des historiographies jacobine et critique. L'imaginaire du complot entretient en fait un double rapport à la violence en constituant, d'une part, un moteur d'action et, de l'autre, une source de justification et de mythification nécessaire pour masquer le déferlement des furies. Ce processus de légitimation fournira les éléments constitutifs du premier récit national.In his Origins of Contemporary France, Hyppolyte Taine assimilates the storming of the Bastille to a descent into anarchy. The crowd is portrayed as a ‘primitive animal’, irrational and left to its instincts. The Jacobin historiography of the French Revolution has since criticized this depiction of the crowd as animals by highlighting political, social and economic rationales behind the people’s acts of violence. The events of July 1789 actually show how violence can be complex phenomenon that is destructive and founding at the same time. This article will explain the processes by which popular violence contributed in fine to the birth of the France nation. The conspiracy imaginations

Leur figure s'est transformée en Orient musulman à partir du Xe siècle, largement sous l'influence du Shâh-nâma, quand se sont multipliées les dynasties indépendantes, puis à la suite de l'irruption des Turcs, des Croisés et des Mongols. Les exemples de Saladin et de Gengis Khan illustrent le renouvellement des modèles, leur extension et leurs réinterprétations successives. La créativité mythique apparaît comme un acte culturel, de portée éminemment politique. La carrière d'un grand conquérant comme Tamerlan a servi de modèle à ses épigones pour justifier leurs prétentions territoriales. Les références bibliques attestées dans le Coran ont permis d'intégrer les Turcs, puis les Mongols, dans l'histoire de la Création, comme descendants de l'un des trois fils de Noé.

  13. Could a secular increase in organic burial explain the rise of oxygen? Insights from a geological carbon cycle model constrained by the carbon isotope record

    The stable isotopes of carbon in marine sedimentary rock provide a window into the evolution of the Earth system. Conventionally, a relatively constant carbon isotope ratio in marine sedimentary rocks has been interpreted as implying constant organic carbon burial relative to total carbon burial. Because organic carbon burial corresponds to net oxygen production from photosynthesis, it follows that secular changes in the oxygen source flux cannot explain the dramatic rise of oxygen over Earth history. Instead, secular declines in oxygen sink fluxes are often invoked as causes for the rise of oxygen. However, constant fractional organic burial is difficult to reconcile with tentative evidence for low phosphate concentrations in the Archean ocean, which would imply lower marine productivity and—all else being equal—less organic carbon burial than today. The conventional interpretation of the carbon isotope record rests on the untested assumption that the isotopic ratio of carbon inputs into the ocean reflect mantle isotopic values throughout Earth history. In practice, differing rates of carbonate and organic weathering will allow for changes in isotopic inputs, as suggested by [1] and [2]. However, these inputs can not vary freely because large changes in isotopic inputs would induce secular trends in carbon reservoirs, which are not observed in the isotope record. We apply a geological carbon cycle model to all Earth history, tracking carbon isotopes in crustal, mantle, and ocean reservoirs. Our model is constrained by the carbon isotope record such that we can determine the extent to which large changes in organic burial are permitted. We find both constant organic burial and 3-5 fold increases in organic burial since 4.0 Ga can be reconciled with the carbon isotope record. Changes in the oxygen source flux thus need to be reconsidered as a possible contributor to Earth's oxygenation. [1] L. A. Derry, Organic carbon cycling and the lithosphere, in Treatise on

Le prisonnier n’y dénonce pas seulement l’iniquité de sa propre incarcération, mais met en accusation le système judiciaire et politique qui l’a conduit derrière les barreaux pour son activisme politique. Cette dénonciation s’appuie essentiellement sur le socle juridique qui protège les citoyens « libres », tel qu’il est possible de le dégager de la Magna Carta et de la longue jurisprudence de la Common Law. Cette base strictement légale permet à Lilburne de dénoncer toute forme de détention arbitraire ou abusive (tribunaux d’exception, prison pour dettes, etc., mais aussi les conditions de détention auxquelles sont soumis les prisonniers. Elle lui permet enfin de pousser jusqu’à remettre en cause la prison pénale elle-même et même, au nom du droit fondamental des citoyens à la liberté, toute forme d’incarcération prolongée, c’est-à-dire, foncièrement, l’institution carcérale elle-même.Through the contextual study of one of the pamphlets, Liberty vindicated, due to John Lilburne, the most charismatic leader of the so-called Levellers, we are interested in what we may call the invention of the prison’s political writing.

Concluiu-se que a meia-seca em leito fixo e a secagem em secador de fluxos concorrentes, além de reduzir o tempo de operação, poderá contribuir para melhor preservar as qualidades que o produto adquire no campo.The general objective of this study was the evaluation of a system for coffee drying, using partial drying in fixed bed dryer and complementary drying in an intermittent concurrent flow batch dryer. The experiment was carried out in the Vegetable Products Processing Area, DEA-UFV. The drying tests were accomplished in completely randomized design. The coffee was harvested on the ground by manual striping process. The fruits were pre-processed by drying of ripe, overripe and greenish cherries. For the preliminary drying, the initial coffee moisture content varied from 68.9 to 71.3% w.b. with the drying being interrupted with moisture content between 44.0 and 47.5% w.b. In the complementary drying phase the final moisture

    Full Text Available La fortification Horodca Mică est située dans la zone centrale de l'espace pruto-dniesterien, aux environs des sources de la rivière Botna, et elle est devenue objet des recherches systématiques depuis 2006. Plusieurs des résultats obtenus depuis cette date on été publiés entre temps. On compte parmi ceux-ci une étude concernant les éléments défensifs de la forteresse, où l'on a mis en avant l'hypothèse d'une fortification par étapes, du promontoire, alternées avec des destructions périodiques. Au départ, on avait plus insisté sur la première phase d'édification du système défensif, en décrivant ses éléments constitutifs, les techniques utilisées dans le processus d'édification, mais aussi l'évolution de la fortification même, jusqu'au dévastateur incendie qui a écroulé la construction défensive. Dans cet article on a repris le débat portant sur le système défensif. L'hypothèse sur laquelle on se fonde admet l'existence de trois autres phases de refortification du même espace, suite à la première destruction. Pour l'argumentaire de ce point de vue on s'est proposé de présenter dans un premier temps, le tableau des observations objectives, enregistrées sur le terrain, et dans un deuxième temps, partant de ces observations, offrir une explication de la vision que nous avons construit. Cette analyse porte y compris sur les modalités d'édification du système défensif dans chacune des phases identifiées, sur les techniques et matériaux utilisés, ainsi que des raisonnements concernant les repères chronologiques. On est donc d'avis que dans ces phases ultérieures de fortification du promontoire, a été procédé de la même manière que dans la première : un fossé a été creusé (en réalité c'est l'ancien qui a été étendu en largeur, derrière a été montée une palissade complexe, en bois (sur le sommet même de la vague constituée suite à l'écroulement de la construction de la phase

    This is an updated version of the original Cochrane review published in Issue 11, 2010 (Derry 2010). Migraine is a common, disabling condition and a burden for the individual, health services and society. Many sufferers choose not to, or are unable to, seek professional help and rely on over-the-counter analgesics. Co-therapy with an antiemetic should help to reduce nausea and vomiting, which are commonly associated with migraine. To determine the efficacy and tolerability of paracetamol (acetaminophen), alone or in combination with an antiemetic, compared with placebo and other active interventions in the treatment of acute migraine in adults. We searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE and the Oxford Pain Relief Database for studies through 4 October 2010 for the original review, and to 13 February 2013 for the update. Two clinical trials registers (ClinicalTrials.gov and gsk-clinicalstudyregister.com) were also searched on both occasions. We included randomised, double-blind, placebo- or active-controlled studies using self-administered paracetamol to treat a migraine headache episode, with at least 10 participants per treatment arm. Two review authors independently assessed trial quality and extracted data. Numbers of participants achieving each outcome were used to calculate relative risk and numbers needed to treat (NNT) or harm (NNH) compared with placebo or other active treatment. Searches for the update identified one additional study for inclusion. Eleven studies (2942 participants, 5109 attacks) compared paracetamol 1000 mg, alone or in combination with an antiemetic, with placebo or other active comparators, mainly sumatriptan 100 mg. For all efficacy outcomes paracetamol was superior to placebo, with NNTs of 12 (19% response with paracetamol, 10% with placebo), 5.0 (56% response with paracetamol, 36% with placebo) and 5.2 (39% response with paracetamol, 20% with placebo) for 2-hour pain-free and 2- and 1

Derrière cet indicateur se cachent des politiques de gestion des ressources humaines largement déterminées par les questions de productivité du travail. En effet, ces entreprises commerciales ont à résoudre une équation majeure consistant à placer la bonne quantité de personnel au bon endroit et au bon moment, du fait de la forte irrégularité des affluences de la clientèle dans leurs points de vente. L’usage du temps de travail acheté constitue donc une variable fondamentale dans la maîtrise des coûts de production.

Commercial companies are constantly seeking to move large numbers of staff members to the right place at the right time, a complicated exercise given customers’ irregular presence at points of sale. The way that companies use the working time that they have purchased therefore constitutes a key variable in controlling production costs. The solutions they choose will affect the temporal conditions determining employees’ in-store execution of tasks. Such activities tend to fluctuate between intensity and overflow. In turn, this strongly affects how staff members apprehend tasks; relations with customers; and their sense of serenity at work.El comercio masivo es un sector de actividad cuyos resultados

Pourtant, derrière l’apparente évidence du « tourisme sexuel » comme expression de sens commun, rares sont les enquêtes qui explicitent la réalité concrète des échanges prostitutionnels. En adoptant une démarche ethnographique, l’article décrit le fonctionnement de Patpong, un quartier rouge de Bangkok dédié à une clientèle internationale. Par la description des offres disponibles, des revenus générés, des codes et des pratiques, la complexité de l’espace réapparaît. Il s’agit de donner à voir la réalité des échanges pour interroger l’articulation entre commerce et sexualité. L’analyse ethnographique du tourisme sexuel permet ainsi de souligner la diversité des pratiques et de rappeler que les formes les plus visibles — et les plus commentées — d’échanges prostitutionnels éclipsent trop souvent une pluralité d’expériences qui participe pourtant au succès de ces ruelles mondialement connues. So-called sex tourism is condemned as an immoral form of international tourism, a serious failure of globalization requiring political action against the “sexual exploitation” suffered by millions of women and children. Yet behind the common and seemingly evident understanding of “sexual tourism,” few studies have focused on the actual reality of such relations. Based on an ethnographic study, this article presents the structure of Patpong, a red-light district of Bangkok dedicated to international tourism.

    Full Text Available La migration du pétrole vers les réservoirs et les pièges, et particulièrement son expulsion hors de la roche-mère où il s'est formé (migration primaire, est demeurée longtemps un des problèmes les plus mal connus de toute la géologie pétrolière. Le déplacement du pétrole et du gaz s'effectue en phase hydrocarbure séparée. L'eau, souvent considérée comme le véhicule du pétrole dans la migration, joue en fait un rôle négatif : il faut que la saturation en eau ait suffisamment diminué (par expulsion et que la saturation en hydrocarbures ait suffisamment augmenté (par génération à partir du kérogène pour que l'écoulement d'une phase hydrocarbure devienne possible. Le moteur de cette expulsion est le gradient de pression : l'élévation de la pression dans l'espace poreux des roches-mères résulte de trois causes (la charge sédimentaire, la genèse des hydrocarbures, et l'expansion thermique de l'eau. La microfissuration, qui survient quand la pression interne des fluides dépasse la résistance mécanique de la roche peut jouer un rôle important. Les observations dans les bassins sédimentaires de cas bien documentés sont encore trop rares. Il est, en particulier, difficile de calculer les réserves mobilisées à l'échelle d'un permis ou d'un bassin. La modélisation numérique de la migration, associée à celle de la genèse du pétrole et du gaz, offre des perspectives dans ce sens, mais elle demande encore des travaux complémentaires. Parmi les conséquences de la migration, on peut citer : la possibilité de corrélation huile/roche-mère, la teneur plus faible en produits lourds dans les réservoirs que dans les roches-mères et le rôle souvent joué par un déplacement où hydrocarbures liquides et gazeux forment une phase unique, qui migre en laissant progressivement derrière elle les fractions plus lourdes, par condensation rétrograde.

Un des principaux problèmes dans la prise en charge du VIH/sida au Viêt Nam fut l’absence de médicaments appropriés, efficaces et accessibles. Contrairement à la Chine, la médecine traditionnelle au Viêt Nam ne s’est pas adaptée, ni n’a réussi à développer durablement de produits spécifiques. Pourtant, l’OMS favorise et incite les thérapeutes traditionnels à participer et à proposer des solutions et pas seulement dans le cadre de soins complémentaires ou palliatifs. On a pu parfois même observer des attitudes plutôt répressives de la part des autorités vietnamiennes à l’égard d’un médicament traditionnel qui n’était pas passé par l’evidence based medicine. En revanche, contrairement à la Chine, le Viêt Nam s’est orienté vers une production locale de médicaments génériques pour répondre aux besoins locaux et baisser le coût de la prise en charge du VIH. À l’aide d’une analyse de contenu de la presse vietnamienne sur le sujet nous tenterons de comprendre les enjeux politiques, économiques et culturels qui se cachent derrière le faible développement de médicaments traditionnels dans le cadre de la prise en charge du VIH/sida. Nous montrerons que l’occidentalisation pendant la période coloniale, l’ouverture du pays depuis le début des années 1990, la globalisation (vue ici comme la multiplication des échanges avec les pays occidentaux et l’intégration du Viêt Nam au reste du monde et à l’ASEAN et la chaîne de production du médicament pharmaceutique ont modifié les pratiques de pluralisme médicamenteux ainsi que la politique nationale en matière de santé, avec des implications à plus ou moins long terme sur les pratiques

    Stekl, Peter J.; Flanagan, Sarah M.

    1992-01-01

    Communities in the lower Merrimack River basin and coastal river basins of southeastern New Hampshire are experiencing increased demands for water because of a rapid increase in population. The population in 1987 was 225,495 and is expected to increase by 30 percent during the next decade. As of 1987, five towns used the stratified-drift aquifers for municipal supply and withdrew an estimated 6 million gallons per day. Four towns used the bedrock aquifer for municipal supply and withdrew an average of 1 .6 million gallons per day. Stratified-drift deposits cover 78 of the 327 square miles of the study area. These deposits are generally less than 10 square miles in areal extent, and their saturated thickness ranges front less than 20 feet to as much as 100 feet . Transinissivity exceeds 4,000 square feet per day in several locations. Stratified-drift aquifers in the eastern part are predominantly small ice-contact deposits surrounded by marine sediments or till of low hydraulic conductivity. Stratified-drift aquifers in the western part consist of ice-contact and proglacial deposits that are large in areal extent and are commonly in contact with surface-water bodies. Five stratified-drift aquifers, in the towns of Derry, Windham, Kingston, North Hampton, and Greenland, have the greatest potential to supply additional amounts of water. Potential yields and contributing areas of hypothetical supply wells were estimated for an aquifer in Windham near Cobbetts Pond and for an aquifer in Kingston along the Powwow River by use of a method analogous to superposition in conjunction with a numerical ground-waterflow model. The potential yield is estimated to be 0 .6 million gallons per day for the Windham-Cobbetts Pond aquifer and 4 .0 million gallons per day for the Kingston-Powwow River aquifer. Contributing recharge area for supply wells is estimated to be 1.6 square miles in the Windham-Cobbetts Pond aquifer and 4.9 square miles in the Kingston-Powwow River aquifer

    Full Text Available L’écriture poétique de William Blake est d’abord hétérogène au sens de multiple et de variée : pastorale, argumentaire démonstratif, poèmes pour enfants, discours didactiques, épopées lyriques, exhortations sont autant de modes qui se déclinent de façon apparemment désordonnée dans son œuvre. Les parodies bibliques ou swedenborgiennes, les imitations de genres littéraires bien établis et le recours au procédé de la parabole ne doivent cependant pas masquer le fait que derrière cette diversité, se trouvent une thématique et un objectif qui confèrent à l’ensemble poétique son unité. C’est en effet dans une fonction transformatrice, qui passe en particulier par la lutte contre les habitudes de pensée (et d’écriture, que se situe l’enjeu central des poèmes. Est alors hétérogène l’écriture qui, conditionnée par une lecture menée en fonction d’états spirituels identifiés par le poète, engendre l’autre (le « soi » face au « je », puis l’Autre Lui-même. Devant cet objet qui lui échappe, c’est enfin l’écriture de la critique qui devient nécessairement hétérogène.William Blake’s poetical writing is heterogeneous firstly in the sense of varied and multiple: pastorals, demonstrative arguments, children’s poems, didactic pieces, lyrical epics, exhortations are as many different modes of writing which the poet uses in an apparently disorderly fashion. Nevertheless, the biblical and Swedenborgian parodies, the imitations of well-established genres and the use of the parable should not conceal the fact that under the diversity lie a number of set themes and an objective which ensure the unit y of the works. Indeed, the central stake of these poems is to be found in a transformative function, which implies the denial of our habits of thinking and writing. Heterogeneous is then the mode of writing which, being determined by a practice of reading related to the spiritual states

    Full Text Available Pendant la guerre civile espagnole, l’urgence sanitaire et sociale conduit les femmes de la zone nationale à se mobiliser derrière des associations confessionnelles ou partisanes afin de  participer à l’effort de guerre. Or les forces qui soutenaient le soulèvement antirépublicain fondaient leur conception de l’Etat et de la société sur une stricte répartition des espaces privés et public, ce dernier étant exclusivement réservé aux hommes. Il convenait donc de dépoussiérer ces principes afin de les rendre cohérents avec la réalité du terrain, sans pour autant enfreindre trop visiblement l’ordre national et catholique. La reconnaissance par Franco du Secours social (2 février 1937, puis la création du Service social présenté comme l équivalent féminin du service militaire (décret du 7 octobre 1937 sont les premières étapes du processus d’officialisation d’un devoir national de présence des femmes dans l’espace public à des fins exclusives d’assistance, et sous le strict contrôle de l’Etat national et catholique. Ce devoir national, la presse féminine se chargera d’en préciser les limites dans une dernière étape qui se poursuit après guerre, en exaltant un modèle de femme espagnole dont l’unique aspiration, quand l’urgence l’oblige à accomplir de grandes choses au nom de la foi et de la patrie, serait de retrouver au plus vite la quiétude du foyer où réside sa vocation première et transcendante. C’est la théorie de la « guerre totale » qui arrache les femmes à leur nature, le temps d’une guerre.During the Spanish civil war, due to a lack of sanitary and social services, the women of the national zone had to support the war effort. But the forces that supported the antirepublican uprising had a conception of the state and society strictly divided between private and public spaces, this being exclusively for men. So it was necessary to get rid of these principles to adjust

Justifier l’appartenance au parti catholique n’est pas une chose facile dans la France du milieu du xviie qui considère majoritairement les ligueurs comme des fanatiques violents ou comme des hypocrites, vendus aux puissances étrangères, notamment l’Espagne. La réhabilitation menée par l’auteur consiste à dire que Marillac faisait partie d’une « bonne ligue », représentée notamment au parlement de Paris. C’est cette bonne ligue parlementaire qui en juin 1593, sous l’impulsion de Marillac, aurait sauvé la monarchie en promulguant le célèbre arrêt Lemaître, cassant toutes les décisions que les états généraux étaient susceptibles de prendre pour transmettre la couronne de France à un prince étranger. Nous avons choisi d’étudier cette source en posant trois questions.1 Les événements rapportés par l’auteur sont-ils crédibles ? Ces faits semblent exacts dans l’ensemble. Mais le point central de la démonstration, à savoir le rôle essentiel de Marillac, n’est à ce jour étayé par aucune autre source. 2 Que nous apprend ce document sur les pratiques d’historien de Lefèvre de Lezeau ? Plusieurs indices nous laissent penser que ce texte pourrait être à l’origine autonome, et aurait été tardivement inséré par l’auteur dans sa Vie de Marillac.3 Quelle est la stratégie d’écriture de l’auteur ? La réhabilitation de la bonne Ligue est rendue acceptable car elle se fait au miroir du parti royaliste : comme le royaliste, le bon ligueur est modéré, courageux, il a le sens de l’état, et c’est un « bon français », gallican et opposé aux ambitions espagnoles. Mais derrière ces éléments consensuels, l’auteur ne remet pas en cause la légitimité de la Ligue ; il en fait même le premier instrument de la Providence pour pacifier la France. Subrepticement

    Full Text Available Em experimento instalado numa cultura de café 'Catuaí' cultivado há 12 anos, na Fazenda Múquem - FAEPE/UFLA, localizada em Lavras MG, com espaçamento de 3,5 m entre linhas e 0,8 m entre plantas, analisou-se o efeito da época de inicio da irrigação e de parcelamentos da adubação convencional e fertirrigação. O delineamento experimental apresentou 3 blocos, constituídos de 4 parcelas casualizadas, que representam as condições de parcelamento P4 = 36; P3 = 24; P2 = 12 parcelamentos de adubação, no ano agrícola, via fertirrigação e P1 = 12 parcelamentos manuais. Cada parcela foi subdividida em 4 subparcelas sem casualização, representando épocas de inicio de irrigação A = 01/06; B = 15/07; C = 01/09 e D corresponde à testemunha, sem irrigação e adubação parcelada em 4 vezes. A produtividade da cultura (safra 97/98 foi analisada considerando-se café beneficiado colhido por derriça no pano, café colhido no chão e o somatório desses. Os dados de pesagem obtidos foram submetidos à análise de variância e teste de comparação de médias. Da análise de variância, constatou-se efeito significativo para o fator época de irrigação sobre todos os parâmetros estudados; para o fator parcelamento da fertirrigação sobre a produtividade de café de chão; e, para a interação entre os dois fatores, sobre a produtividade de café de pano e total. O teste de comparação de médias mostrou que a subparcela A, irrigada a partir de 01/06, apresentou melhores resultados de produtividade no pano e total de 56,6 sc/ha e 67,7 sc/ha respectivamente, correspondendo a um acréscimo de produtividade de 73,09% e 68,41% em relação às apresentadas pela testemunha não irrigada. Considerando-se a interação entre os fatores época de irrigação e parcelamento de adubação, verificou-se efeito de parcelamentos de adubação apenas dentro da irrigação iniciada em 1/6. Dessa forma, pode-se constatar que 12 aplicações de

    ôle prioritaire du climat.Les évidences stratigraphiques retrouvées dans la zone indiquent que durant l’Holocène inférieur et moyen la vie humaine a été fortement conditionnée par des modifications environnementales induites par des changements climatiques, comme les inondations et la sédimentation sur les berges des fleuves. L’évolution des retenues d’eau derrière les barrages de travertin a aussi influencé les établissements humains dans les vallées montagnardes. Les accumulations détritiques déposées aux pieds des versants dans les secteurs de montagne témoignent, pendant la phase de dégradation du climat, que l’impact humain a contribué, de façon significative, aux processus d’érosion sur les versants et de sédimentation dans les lits fluviaux.La phase d’érosion qui s’est manifestée dans les cours d’eau depuis l’Âge du Fer et jusqu’à la période post-romaine (M. COLTORTI, 1991 a été probablement liée au début d’une nouvelle variation du climat vers des conditions plus humides (J.L. PEÑA et al., 1991 ; C. GIRAUDI, 1998. En effet, pendant cette phase et malgré l’extension progressive des activités agro-pastorales et la probable augmentation des apports détritiques des versants, les processus d’approfondissements des lits fluviaux, ont été dominants dans les Marches centrales (M. COLTORTI, 1991 ; G. CILLA et F. DRAMIS, 2000. Cela laisse penser que, avant les temps modernes, le rôle morphogénétique de l’impact anthropique a été en général subordonné à celui du climat.
