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

    The authors investigated possible alterations in the enzyme activity of catalase and isozyme MB-creatin kinase induced by prolonged exposure of laboratory rodents to a static magnetic field generated by a 0.5 T Magnetic Resonance unit. The results seems to exclude any alterations in the activity of catalase and MB-CK after exposure. However some homeostatic mechanism peculiar to multi cellular organisms might act 'in vivo' to adapt to the effects of the static magnetic field during exposure. [Italian] Scopo del presente lavoro e' indagere l'eventuale verificarsi di alterazioni dell'attivita' enzimatica della catalasi e dell'isoenzima MB della creatinchinasi, indotte dalla prolungata esposizione di animali da laboratorio al campo magnetico statico generato da un Tomografo a Risonanza Magnetica (RM) da 0,5 T. I risultati del lavoro porterebbero a escludere alterazioni dell'attivita' della catalasi e della MB-creatinchinasi conseguenti all'esposizione. Occorre tuttavia rilevare che 'in vivo' possono agire alcuni meccanismo omeospatici, peculiari degli organismi pluricellulari, di adattamento agli effetti dei campi magnetici, che potrebbero essere intervenuti durante l'esposizione.

    In 1931, Dirac advanced a startling prediction about the existence of a new elementary particle, characterized by a magnetic charge of a single polarity: the magnetic monopole. This prediction, that was not based on experimental reasons but on mathematical consistency considerations and the generalization of the formalism of quantum mechanics, illustrates emblematically the Dirac conception of the relationship between physics and mathematics. ----- Nel 1931 Dirac avanz\\`o una sorprendente previsione circa l'esistenza di una nuova particella elementare, caratterizzata da una carica magnetica di un'unica polarit\\`a: il monopolo magnetico. Questa previsione, che non era fondata su ragioni sperimentali ma su considerazioni di consistenza matematica e sulla generalizzazione del formalismo della meccanica quantistica, illustra emblematicamente la concezione di Dirac del rapporto tra fisica e matematica.

    Full Text Available Questo lavoro non è un trattato sul campo geomagnetico e nemmeno
    una rassegna sull'argomento, almeno nel significato che normalmente
    si attribuisce al termine « rassegna »; esso è semplicemente
    un tentativo di condensare in termini comprensibili agli studiosi non
    specializzati ciò che oggi si sa o si ipotizza sul magnetismo terrestre
    e sulle sue cause. Chi scrive si è sempre trovato a disagio di fronte
    alle richieste di una spiegazione sull'origine del campo magnetico
    terrestre: o si cerca di cavarsela con poche parole (« si tratta di correnti
    elettriche indotte nell'interno della Terra » che possono forse accontentare
    chi non si occupa in modo particolare di problemi scientifici
    ma non possono soddisfare un fisico, oppure ci si sente obbligati a
    tentare faticosamente di approfondire, sia per capirli personalmente
    che per poterli poi spiegare agli altri, argomenti e ragionamenti che
    sono in realtà accessibili solo a un fisico teorico ben preparato. Apparentemente
    non esiste una via di mezzo, come del resto in molti altri
    campi della fisica contemporanea.
    La presente monografia rappresenta appunto il tentativo di trovare
    questa via di mezzo: nel terzo capitolo, dedicato alle teorie sull'origine
    del campo geomagnetico, si cerca di descrivere qualitativamente
    i principali processi fisici proposti come sorgenti del campo,
    dopo un accenno ai fondamenti fisici e matematici sui quali sono state
    elaborate le varie teorie. Senza farmi soverchie illusioni di essere riuscito
    nell'intento, mi dichiarerei tuttavia soddisfatto se questo lavoro
    destasse sull'argomento l'interesse di qualche giovane ricercatore, incoraggiandolo
    ad un approfondimento.

  5. Characterization of residual soils of the region of Campos dos Goytacazes, RJ, Brazil, slip for use in artistic ceramics

    International Nuclear Information System (INIS)

    This work was conducted in the city of Campos dos Goytacazes/RJ, in which four residual soils collected in the region were technologically characterized. We sought to determine their properties, such as analysis of the colors after firing, aiming at its use in ceramic art. To this end the tests were conducted in the laboratories of the Universidade Estadual do Norte Fluminense Darcy Ribeiro (UENF) and that are granulometry (by sieving and sedimentation), specific mass of grains, chemical analysis by X-ray fluorescence, diffraction mineralogical identification X-ray, differential thermal analysis and thermogravimetry. The soils were analyzed before drying at 110 deg C and after burning the different temperatures (500 deg C 750 deg C and 950 deg C). The analyzed results showed the physical composition, chemical and mineralogical of raw material. After burning was possible to observe several color variations. (author)

    The so-called electromagnetic hypersensitivity (RH) syndrome includes a number of unspecific, medically unexplained symptoms attributed to exposure to electric and magnetic fields. As a whole, laboratory tests have provided inconclusive results, in part due to the fact that many individuals show nuclear, inconsistent responses to repeated experimental field-exposures. It has been proposed that such inconsistencies could be due in part to distress caused by the lab test itself. We have developed a test to be conducted at the patient's residence, allowing for long-term follow up of exposure-response assessment and avoiding the laboratory environment and the presence of the researcher as potential stressors and confounding factors. In a pilot test, EMDEX-II magnetometers were used to continuously recording power-frequency magnetic fields in the residence of a patient with perceived EH. The patient's symptoms included distress, headache and dizziness, among other ailments. Magnetographic data of a total of 123 recording days were plotted against the corresponding data on occurrence of the symptoms episodes. As a whole, the results did not show positive linear correlation between the daily occurrence of the episode and the exposures levels recorded during the day or during the day before. These preliminary results are little supportive of the hypothesis that the patient's ailments are caused or worsened by a putative hypersensitivity to residential exposure to power-frequency magnetic fields in the 0.02-4.00 {mu}T range.

    Full Text Available The adoption of no-tillage systems (NT and the maintenance of crop residues on the soil surface result in the long-term increase of carbon (C in the system, promoting C sequestration and reducing C-CO2 emissions to the atmosphere. The purpose of this study was to evaluate the C sequestration rate and the minimum amount of crop residues required to maintain the dynamic C equilibrium (dC/dt = 0 of two soils (Typic Hapludox with different textural classes. The experiment was arranged in a 2 x 2 x 2 randomized block factorial design. The following factors were analyzed: (a two soil types: Typic Hapludox (Oxisol with medium texture (LVTM and Oxisol with clay texture (LVTA, (b two sampling layers (0-5 and 5-20 cm, and (c two sampling periods (P1 - October 2007; P2 - September 2008. Samples were collected from fields under a long-term (20 years NT system with the following crop rotations: wheat/soybean/black oat + vetch/maize (LVTM and wheat/maize/black oat + vetch/soybean (LVTA. The annual C sequestration rates were 0.83 and 0.76 Mg ha-1 for LVTM and LVTA, respectively. The estimates of the minimum amount of crop residues required to maintain a dynamic equilibrium (dC/dt = 0 were 7.13 and 6.53 Mg ha-1 year-1 for LVTM and LVTA, respectively. The C conversion rate in both studied soils was lower than that reported in other studies in the region, resulting in a greater amount of crop residues left on the soil surface.

    Flavour oscillations of neutrinos are a quantum-mechanical effect widely demonstrated. It is explained through interferences of their mass eigenstates, therefore, belonging to the physical area beyond the Standard Model. This work deals with the CIEMAT collaboration in the neutrino experiment Double Chooz. Such an experiment aims to measure the mixture angle {theta}{sub 1}3, one of the PMNS leptonic mixture matrix, with a un reached-before sensibility by decrease of systematic errors. For this, two identical scintillator detectors, equipped with PMT's, will be sited at different distances from two reactors located in the nuclear power plant CHOOZ B (France). The electronic neutrino flux from these reactors will be compared, explaining its deficit by flavour oscillations of these particles. The identity of both detectors will be diminished by the magnetic field effects on the PMT's response. Therefore, this study serves as for quantifying such an effects as for fitting the magnetic shields design that minimize them. Shielding measurements and final design of magnetic shields as much as the effect these ones cause in the PMT's response immersed in a monitored magnetic field are presented. (Author) 85 refs.

    The charged particles that constitute the plasma in the tokamaks are located in magnetic fields that determine its behavior. The poloidal magnetic field of the plasma current and the toroidal magnetic field of the tokamak possess relatively big gradients, which produce drifts on these particles. These drifts are largely the cause of the continuous lost of particles and of energy of the confinement region. In this work the results of numerical calculations of a modification to the 'traditional' toroidal magnetic field that one waits it diminishes the drifts by gradient and improve the confinement properties of the tokamaks.

    In a cylindrical magnetic topology. the confined plasma experiences 'classic' collisional transport phenomena. When bending the cylinder with the purpose of forming a toro, the magnetic field that before was uniform now it has a radial gradient which produces an unbalance in the magnetic pressure that is exercised on the plasma in the transverse section of the toro. This gives place to transport phenomena call 'neo-classicist'. In this work the structure of the toroidal magnetic field produced by toroidal coils of triangular form, to which are added even of coils of compensation with form of half moon is analyzed. With this type of coils it is looked for to minimize the radial gradient of the toroidal magnetic field. The values and characteristics of B (magnetic field) in perpendicular planes to the toro in different angular positions in the toroidal direction, looking for to cover all the cases of importance are exhibited.

Evidence exist to support the notion that exposure of humans to magnetic fields stimulates genotoxic effects, although the actual mechanisms of action or even the true human health consequences resulting from these exposure still remain unclear.

    In this work the magnetic hyperfine field acting on Ce atoms substituting the rare-earths in R Ag compounds (R = Gd e Nd) was studied by means of first-principles electronic structure calculations. The employed method was the Augmented Plane Waves plus local orbitals (APW+lo), embodied in the WIEN2k program, within the framework of the Density Functional Theory (DFT) and with the Generalized Gradient Approximation (GGA) for the exchange and correlation potential. The super-cell approach was utilized in order to simulate for the Ce atoms acting as impurities in the R Ag matrix. In order to improve for correlation effects within the 4f shells, a Hubbard term was added to the DFT Hamiltonian, within a procedure called GGA+U. It was found that the magnetic hyperfine field (MHF) generated by the Ce 4f electron is the main component of the total MHF and that the Ce 4f ground state level is probably a combination of the m{sub l} = -2 and m{sub l} = -1 sub-levels. In addition, the ground-state magnetic structure was determined for Ho Ag and Nd Ag by observing the behavior of the total energy as a function of the lattice volume for several possible magnetic ordering in these compounds, namely, ferromagnetic, and the (0,0,{pi}), ({pi},{pi},0) and (({pi},{pi},{pi}) types of anti-ferromagnetic ordering of rare-earth atoms. It was found that the ground-state magnetic structure is anti-ferromagnetic of type ({pi},{pi},0) for both, the Ho Ag and Nd Ag compounds. The energy difference of the ferromagnetic and antiferromagnetic ordering is very small in the case of the Nd Ag compound. (author)

    The exact solution for the movement of a charged particle in the interaction of an electromagnetic pulse elliptically polarized spreading along a static and homogeneous magnetic field is obtained starting from the equation of force. The solution method allows to solve, in terms of the phase, the trajectory of an accelerated particle by a pulse of arbitrary width and modulated by an encircling in Gaussian form. The reported solutions in this work have diverse applications in the laser-plasma interaction physics. (Author)

    The aim of the present work was to optimize the signal to noise ratio in our NMR imaging system (TORM 005) by improving transducer`s reception quality through better designed coils, balanced tuning circuit for this coils and power decoupling circuits and by reducing interference from the electromagnetic environment. For this purpose, we had to modify the internal electromagnetic shielding and incorporate line filters in the more critical signals paths. Also, new types of coils were developed, improving the signal to noise ratio, and allowing us to make clinical exams with superior quality for several anatomies. Balanced circuits for tuning and matching of the coil were studied and built, allowing a reduction of the coil losses because patient`s load. This produced a more reliable coil tuning after positioning each new patient. Circuits to avoid the receiver input overload and decoupling circuits for the isolation of receiver coils from excitation coil were designed and incorporated to the TORM 005. All these alterations of our imaging system (TORM 005) contributed to a significant improvement in the signal to noise ratio, reliability and reproducibility of the system. This permitted to operate the system routinely for clinical applications, research and development in the area of ultra low magnetic field tomography. (author) 46 refs., 66 figs., 11 tabs.

The persistence of the two Bti formulations employed at that time by the Health Ministry, Vectobac G and Aquabac G, was assayed under laboratory and outdoor conditions. Both formulations were tested at 0.2 g/10 liters of water, the same concentration applied in the field for vector control. The tests were done against Ae. aegypti third instar larvae (Rockefeller strain. In the laboratory, Vectobac G and Aquabac G caused at least 95% mortality until 101 and 45 days after treatment, respectively. In the outdoor assays, test containers of different materials were treated with either formulation and placed in a shaded area. Larvae were introduced each 3-6 days and mortality was recorded 24 and 48 hours later. In the first set of assays, performed in June 2001, mortality levels of 70% or more were attained for 2-5 weeks for both formulations in all containers. The exception was for the iron one that rusted, resulting in low mortality after seven days. In the second set of assays (August 2001, 70% mortality was attained for just 1-2 weeks for all the containers and both formulations.RESUMO Resistência do vetor de dengue, Aedes aegypti, a temephos estimulou sua substituição por Bacillus thuringiensis var. israelensis (Bti desde 2001 no Brasil.

Neste campo, nosso embate dá-se no modo como entendemos o hífen pressuposto na integração psicossocial. A autora propõe que, entre o psicológico e o social, o hífen domina, pois ele é a própria essência relacional que é inerente a cada um dos elementos. Sugere que o modelo para entender o homem e suas circunstâncias proposto por Freud imbrica de forma indissociável o psicológico e o social, a ontogênese e a filogênese, com uma potência que teve impacto sobre todo o campo das Ciências Humanas. A Psicanálise é um instrumento hermenêutico para colaborar na elucidação dos fenômenos sociais. A autora utiliza imagens construídas por Freud e Walter Benjamin e poemas de Carlos Drummond de Andrade para fortalecer o entendimento do hífen psicossocial tanto em sua ação multidimensional quanto em sua organização.

    This paper presents a petrographical characterization of shales from Albacora, Marlim and Marlim Sul fields (offshore Campos Basin, Brazil). The characterization program included petrography analysis of thin section of undisturbed shale samples, scanning electron microscope (SEM) images and energy dispersive spectrometry (EDS) analysis. The tests were realized with the purpose of obtaining information to observe the nature of the rock microstructure. From the results presented herein, the shales can be described as silty and calciferous. The description of the thin sections indicated that all the shale samples are very similar from the compositional and textural point of view. The samples are rich in clay minerals, that show small size grains and seem homogeneous, and carbonatic cement. The samples are constituted by calcite, quartz, kaolinite, smecite, illite, illite/smectite, kaolinite/illite/smectite, feldspar, plagioclase, dolomite, chlorite and pyrite. The samples showed a great amount of calcium, resultant from the microfossils, that covers partially the clay minerals. Pyrite is also observed as small grains disperse throughout the sample with form of agglomerated pyrite framboids, cubo-octahedral and octahedral crystals. The EDS show the presence of picks of Si, Al, Mg, K and Na particles, indicating the presence of clay minerals, calcite, pyrite and chlorite. (author)

    Two simple and fast methods to calculate the penetration time of a longitudinal magnetic field through the wall of a long metallic tube of circular cross section are presented. The first method is based upon the proposition of an 'effective penetration thickness' given by the polar angle average of all possible straight-line transverse penetration paths of field lines through the tube wall. This method provides a quick calculation that yields a remarkably good approximation to experimental and reported values of the penetration time. In the second method the tube is considered as a RL circuit. Thus the penetration time is given by the ratio L{sub T} /R{sub T} where L{sub T} is the inductance of the tube considered as a one turn coil, and R{sub T} is the tube resistance. This method is faster to apply than the previous one but the values obtained provide only a rough approximation to the penetration time. Applications of the two methods are given for the tokamak chambers of the Japanese 'HYBTOK', the Brazilian 'TBR' and the Mexican 'Novillo'. The resulting values of the penetration time approximate very well to the reported ones in the first two cases and to the experimental one in the last. The methods are also applied to calculate the penetration time in two long tubes, one of aluminum and other of copper. Calculated values approximate very well to measured values. (Author)

Coffea arabica is the most cultivated species, accounting for 70% national and world production of coffee. The present study analyzed 6 coffee samples from 6 different regions in the municipality of Campos Gerais, subjected to the treatments raw and roasted, in order to assess their physical and chemical quality based on the parameters of titratable acidity, pH, mo...

  19. Macrorrealismo fenomenológico e campos-experiência

    1995-01-01

    Full Text Available Este artigo critica a concepção predominante, representacionista-neurofisicalista sobre a percepção sensorial. Introduz a noção de "campo-experiência" na tentativa de tratamento ontológico dos dados fenomenológicos da experiência. A idéia geral é que a experiência visual, por exemplo, seria ontologicamente algo assim como um campo-experiência de intencionalidade visual, que se estende por sobre e entre o sistema nervoso central do sujeito da experiência e o objeto distai da visão. Chamo esta posição de macrorrealismo fenomenológico, em contraste com o microrrealismo científico. Qualidades da fenomenalidade não estão subjetivamente dentro do cérebro, mas objetivamente dentro de campos-experiência perceptuais extra-encefálicos, ou, como dizemos, lá fora no mundo. Algumas conseqüências específicas do macrorrealismo fenomenológico são apresentadas.

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

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

    Full Text Available O artigo é um breve apanhado sobre o campo da antropologia no Brasil. Feito originalmente para leitores estrangeiros, pareceu-me melhor deixá-lo como estava a atualizá-lo, na expectativa de que possa ser útil para jovens iniciantes nesse campo, já que o texto refere algumas instituições importantes para a sua formação nos últimos anos — como os programas de pós-graduação e a Associação Brasileira de Antropologia (ABA, e seus temas de pesquisa. Propõe-se aqui também que não apenas a interdisciplinaridade, bastante praticada hoje, mas também relações transversais ao próprio campo da antropologia são desejáveis — isto é, que os antropólogos “urbanos” levem em conta o que dizem os etnólogos, que estes dialoguem com os estudos de gênero etc. De todo modo, a bibliografia incluída ainda é, e continuará a sê-lo por um bom tempo, leitura necessária para pesquisadores que se interessem pela história da antropologia.

    El proyecto de instrumentación de mayor importancia que ha tenido el Instituto de Astrofisica de Canarias en los últimos afios ha sido el diseflo y construcción del te1escopio IAC8O. Este requería del esfuerzo con junto en mec´nica, óptica y electrónica, lo que facilitó la estructuración y el crecimiento de los respectivos grupos de trabajo, que posteriormente se integraron en departamentos En su origen (1977), el telescopio IAC80 fue concebido como un sistema clásico tipo Cassegrain, con una razón focal F/i 1.3 para el sistema Casse grain y una razón focal F/20 para el sistema Coudé. Posteriormente, aunque se mantuvo la filosofia de que el sistema básico fuera el F/11.3, se consideró conveniente el diseño de secundarios para razones focales F/16 y F/32, y se eliminó el de F/20. Sin embargo, dada la importancia relativa que un foco estrictamente fotográfico tiene en un telescopio moderno, diseñado básicamente para fotometría fotoeléctrica y con un campo util mínimamente de 40 minutos de arco, se decídió Ilevar a cabo el diseño de un secundario F/8 con un sistema corrector de campo, pero que estuviera formado únicamente por lentes con superficies esféricas para que asl su construcción fuera posible en España ó en México. La creciente utilización de detectores bidimensionales para fines de investigación astron6mica y la viabilidad de que en un futuro cercano éstos tengan un área sensible cada vez mayor, hicieron atractiva la idea de tener diseñado un sistema corrector de campo para el foco primario (F/3), con un campo útil mínimo de un grado, y también con la limitante de que sus componentes tuvieron sólamente supérficies esféricas. Ambos diseños de los sis-temas correctores de campo se llevaron a cabo, en gran medida, como parte de un proyecto de colaboración e intercambio en el área de diseño y evaluación de sistemas ópticos.

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

As sementes dessa espécie, entretanto, têm apresentado dificuldades de germinação em virtude da impermeabilidade do tegumento. Para a superar o problema, instalou-se um ensaio no Laboratório de Análise de Sementes da Universidade Federal de Goiás, com sementes colhidas na cidade de Jussara, Goiás, em agosto de 2000. As amostras de sementes foram submetidas a tratamento com ácido sulfúrico (H2SO4 P. A. por períodos de 0, 5, 10, 15 e 20 minutos e, posteriormente, ao teste-padrão de germinação. A análise dos dados revelou que a imersão das sementes em H2SO4 por um período de cinco a quinze minutos produziu a maior percentagem de germinação (98%.

    The petroleum systems of the Campos Basin contains 60 billion barrels of discovered oil in place and 775 billion cubic meters of natural total gas in place, comprising one of the most prolific petroleum systems in South America . It is located in southeast Brazil covering about 100,000 km{sup 2} with 44 oil fields, seven giants, holding up to 90% of total Brazilian oil reserves and 50% of total natural gas reserves. The Campos Basin produces mostly from turbiditic sandstones of the Carapebus formation (Cretaceous-Tertiary), comprising the biggest part of the total production. Other important reservoirs are calcarenites of the Macae formation (Albian), bioclastic lacustrine limestones of the Lagoa Feia formation (Barremian), and fractured basalts of the Cabiunas formation (Neocomian). The source rocks are saline-to-brackish lacustrine water of the Lagoa Feia formation (Barremian) containing 5% TOC average, an average thickness about 100 m with a maximum of 500 m in depocenters, covering approximately 50,000 km{sup 2}. Trapping style is chiefly structural for the Cabiunas formation; structural-stratigraphic for the coquinas (bioclastic limestones of the Lagoa Feia formation), where pinch-out of the coquinas is a common feature; strongly structural for the calcarenites of the Macae formation (rollovers related to salt tectonics), and finally structural combined with sandstone pinch-out for the Cretaceous and Tertiary turbidites of the Carapebus formation. At the Corvina-Parati depo center, thermal basin modeling suggests the onset of oil generation in late Albian, reaching its maximum during the Miocene and it is still going on to present days. The top of oil window is about 4,5000 m deep and transformation rate reaches up to 70%. Seismically, the Campos Basin shows distinct response and characteristics according to lithologies and ages. The lowermost sequence (Lagoa Feia and Cabiunas formations) is poor in seismic attributes; the geological model is more adequate for

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

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

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

  18. The Sondalo gabbro contact aureole (Campo unit, Eastern Alps): implications for mid-crustal mafic magma emplacement

    Contact aureoles rimming plutonic rocks are the locus of metamorphism and deformations witnessing magma emplacement mechanisms in the crust. In this study, structural and petrological observations are combined to mineral equilibria modelling to unravel the polyphase tectono-metamorphic history of the Permian Sondalo gabbro and its host rock, the Campo unit (Eastern Alps). The Campo unit consists of Grt-St-Ms-Bt-Pl-Qtz ± Sil ± And ± Crd mica schists attesting of a Carboniferous prograde P- T path, reaching 6 kbar/600 °C and subsequently 5.6 kbar/650 °C. This metamorphism is coeval with the formation of a sub-vertical NE-SW trending foliation (S1) and its overprint by a sub-vertical NW-SE trending foliation (S2). The heat brought by the Permian intrusives subsequently caused heating of the Campo unit at around 3-4 kbar/540 °C reflected by regional static crystallization of cordierite and andalusite porphyroblasts. During the intrusion of the Sondalo gabbro, thermal peak conditions are recorded by Grt-Sil-Spl-Crd-Ilm granulitic xenoliths at ~5.5 kbar/930 °C, subsequently exhumed at ~4 kbar during the development of a new foliation (S3). This foliation is localized around the pluton and moderately dips away from the centre of the pluton. In the migmatitic contact aureole, Grt-Sil-Bt-Pl-Qtz-Ilm and Grt-Sil-Crd-Spl-Bt-Kfs-Ilm residual rocks bear the new foliation (S3) and document a decompression from 6 kbar/750 °C to 5 kbar/725 °C and from 5.2 kbar/800 °C to reach 4.8 kbar/770 °C, respectively. The P- T- d paths recorded by the host rock and the xenoliths point to a two-step magma emplacement. First the Sondalo gabbro intruded the Campo unit causing heating of the host rock without deformation at 3-4 kbar. Second, the ductile flow along the pluton margins developed a new foliation (S3) during exhumation of the pluton and its immediate contact aureole from 6 to 4 kbar. Altogether, it indicates a progressive increase in mechanical coupling between the pluton

    Full Text Available The study aimed to fit mathematical models for the construction of Site Index curves and to estimate heights at different ages for Eucalyptus grandis in the Campos Gerais region, Parana State. The data used to fit the models came from permanent, temporary plots and pre-harvesting inventory, covering ages from 2.5 to 26.5 years. Several models were tested to represent the sites and the hypsometric relationship. The Site Index curves were constructed by the guide-curve method. For the Site Index, the Chapman-Richards model showed the best fit and precision statistics, generating 5 Site Index curves (range of 5 m with the Chapman-Richards model. The four hypsometric models tested showed satisfactory performance and similar statistics and the inclusion of the variables dominant height or site index did not substantially improve the goodness of fit statistics, but the residues were more homogeneous and closer to zero.

    2012-09-01

    In the province of Chaco, Argentina, there is a very unique dispersion of metallic meteorites called ``Campo del Cielo''. One of the meteoric fragments of this dispersion, the meteorite called ``El Chaco'', consisting of 37 tons, is the second heaviest in the world. These meteorites are of great importance to the worldview of the Moqoit, aboriginal people that inhabit this region. For the local Creole population the meteorites are also relevant, that's why they have being cited in numerous documents and reports since the colonial period. During the first months of 2012, two Argentine artists and the Artistic Director of the German contemporary art exhibition called dOCUMENTA (13) tried to move ``El Chaco'' meteorite to Germany in order to exhibit it as an artistic object. Due to the fact that moving the meteorite could have a negative impact according to the Moqoit cosmology and that they were not able to participate in the decision they begun a manifestation against the movement of El Chaco. The opposition made by aboriginal communities and experts in cultural astronomy was able to stop the transfer. The whole process and its impact on the local community have promoted a deep discussion about art, science and cultural colonialism. In this paper we aim to address this debate and its consequences. This will allow us to think about contemporary forms of colonialism that are hidden in many scientific and artistic projects. Furthermore, we aim to debate about the most effective ways of protecting astronomical heritage in the Third World.

    Full Text Available In this paper we present an example of a specific metric which geometrizes explicitly a light-like four-vector potential (chiral field. The geometrization shows that such a vector has the same geometrical structure as a gravitational Kerr field. We discuss a theoretical proposition that a rotating body generates, besides a special gravitational field, a magnetic-type gauge field which might be identified with a chiral geometrized field. This chiral field represents a novel type of field because we cannot identify it with any of the known electromagnetic fields. As an application of this theory we discuss the morphology of the planets around the sun.En este trabajo se presenta un ejemplo de una métrica especifica que geometriza explícitamente un potencial cuadrivector tipo luz (campo quiral. La geometrización muestra que tal vector tiene la misma estructura geométrica que un campo gravitacional Kerr. Se discute una proposición teórica que un cuerpo rotante genera, su gravitación y el calibre de campo tipo magnético que puede ser identificado con un campo quiral geometrizado. Este campo quiral representa un tipo novedoso de campo que no puede ser identificado con alguno de los campos electromagnéticos conocidos. Como aplicación de esta teoría se discute la morfología de los planetas alrededor del sol.

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

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

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

    Science.gov (United States)

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

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

    The Albacore and Marlim giant fields are located in the province of Campos basin, about 110 km (68 mi) offshore Cape Sao Tome, in water depths ranging from 200 m (656 ft) to 2,000 m (6562 ft). The Albacora field was discovered in September 1984 by the wildcat 1-RJS-297, drilled in 293 m (961 ft) of water. Subsequently, the wildcats 1-RJS-305 and 1-RJS-342 extended the field limits to deeper waters. The Albacora field is approximately 235 km{sup 2} (90 mi{sup 2}) in area, with an estimated volume of 4.5 billion bbl of oil in place. The Marlim field was discovered in February 1985 by the wildcat 1-RJS-219A, in a water depth of 853 m (2,800 ft). The Marlim field area is about 152 km{sup 2} (58 mi{sup 2}), and the latest estimate of oil in place is about 8.2 billion bbl. The Marlim complex encompasses Marlim field itself and the surrounding proved and potential areas known as East-of-, West-of-, and South-of-Marlim, respectively. The current estimated volume of oil in place in the Marlim complex is close to 13.9 billion bbl, with a total surface of about 350 km{sup 2} (135 mi{sup 2}). Oil production in the Albacora field comes from Lower Cretaceous (Albian) and Tertiary (Eocene, Oligocene, and Miocene) turbidite reservoirs. Oligocene turbidite sandstones are the potential reservoirs in the Marlim field. These deposits are genetically associated with sea level variations and are mainly composed of massive sandstones and, subordinately, of contourites. Both fields are structurally and stratigraphically controlled accumulations. Hydrocarbons are trapped in anticlines and/or faulted blocks associated with salt tectonics. Stratigraphic contributions result from sandstone bodies pinching out against shales and marls. The development of these fields has been supported by three-dimensional seismic data. The Albacora field is being gradually put on stream from shallower to deeper waters.

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

  16. Actual stage of organic geochemical knowledge from Campos and Espirito Santo basins, Brazil

    International Nuclear Information System (INIS)

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

  2. Handling of Solid Residues

    International Nuclear Information System (INIS)

    The topic of solid residues is specifically of great interest and concern for the authorities, institutions and community that identify in them a true threat against the human health and the atmosphere in the related with the aesthetic deterioration of the urban centers and of the natural landscape; in the proliferation of vectorial transmitters of illnesses and the effect on the biodiversity. Inside the wide spectrum of topics that they keep relationship with the environmental protection, the inadequate handling of solid residues and residues dangerous squatter an important line in the definition of political and practical environmentally sustainable. The industrial development and the population's growth have originated a continuous increase in the production of solid residues; of equal it forms, their composition day after day is more heterogeneous. The base for the good handling includes the appropriate intervention of the different stages of an integral administration of residues, which include the separation in the source, the gathering, the handling, the use, treatment, final disposition and the institutional organization of the administration. The topic of the dangerous residues generates more expectation. These residues understand from those of pathogen type that are generated in the establishments of health that of hospital attention, until those of combustible, inflammable type, explosive, radio-active, volatile, corrosive, reagent or toxic, associated to numerous industrial processes, common in our countries in development

  4. Thiometon residues in cucumber

    International Nuclear Information System (INIS)

    In the Islamic Republic of Iran, vegetables are treated repeatedly with pesticides to control pests and diseases. Crops harvested shortly after pesticide application are probably contaminated by pesticides that are toxic to humans. Pesticide residues in vegetables are especially important, since these crops are ingested directly by humans. In recent years, farmers have been using more persistent pesticides to protect their crops because of increasing pesticide prices. Field trials were carried out to determine the residues of thiometon, a systemic insecticide used on cucumber. In 1993 and 1994, Ekatin (a 25% thiometon emulsifiable concentrate) was applied with a knapsack sprayer to cucumber (var. Daminus) at late flowering at dilutions of 1:1000 and 2:1000. Plots were 25 m2 in three replicates and were sampled 3, 6, 10, 15, 19 and 24 days after application. The samples were extracted with acetonitrile and cleanup was carried out using thin layer chromatography. Thiometon and two metabolites (thiometon sulphide and thiometon sulphone) were analyzed by gas chromatography. In 1994, the amount of thiometon sulphide determined 24 days treatment was 2 ppm in the peeled cucumber, which exceeded the maximum residue limit of 0.5 ppm. The total thiometon residues were higher in the peeled cucumber than those in the cucumber peel. Thus, peeling is ineffective for reducing the systemic residues of thiometon. Likewise, in this experiment lower dilution caused higher rather than lower thiometon residues in cucumber. The rapid disappearance of thiometon residues 2 weeks after treatment suggests that storing cucumbers at room temperature may be a better strategy for reducing excessive thiometon residues. Alternatively, a contact insecticide could be used. Thus, the bulk of the surface residues could be removed by washing or peeling. (author). 5 refs, 4 figs

Diante deste contexto, este trabalho objetivou descrever e compreender como ocorre a reconfiguração de campo do familiar cuidador responsável pelo portador de Alzheimer. Para tanto, realizou-se uma pesquisa qualitativa, pautada na perspectiva fenomenológica e na teoria de campo, fundamento teórico da abordagem Gestáltica, e utilizou-se o método de Amedeo Giorgi. O estudo desenvolveu-se com três cuidadoras familiares de pacientes portadores de Alzheimer diagnosticados havia mais de seis meses. Encontraram-se quatro categorias que descrevem a reconfiguração do campo das cuidadoras: Assumindo a responsabilidade em cuidar; Mudanças na família; Rede de apoio social; e Estratégias de enfrentamento. Concluiu-se que o processo de reconfiguração do campo do familiar cuidador é longo e passa por diversas reestruturações dinâmicas e estruturais.

  12. Characterization of Hospital Residuals

    International Nuclear Information System (INIS)

    The main objective of this investigation is the characterization of the solid residuals. A description of the handling of the liquid and gassy waste generated in hospitals is also given, identifying the source where they originate. To achieve the proposed objective the work was divided in three stages: The first one was the planning and the coordination with each hospital center, in this way, to determine the schedule of gathering of the waste can be possible. In the second stage a fieldwork was made; it consisted in gathering the quantitative and qualitative information of the general state of the handling of residuals. In the third and last stage, the information previously obtained was organized to express the results as the production rate per day by bed, generation of solid residuals for sampled services, type of solid residuals and density of the same ones. With the obtained results, approaches are settled down to either determine design parameters for final disposition whether for incineration, trituration, sanitary filler or recycling of some materials, and storage politics of the solid residuals that allow to determine the gathering frequency. The study concludes that it is necessary to improve the conditions of the residuals handling in some aspects, to provide the cleaning personnel of the equipment for gathering disposition and of security, minimum to carry out this work efficiently, and to maintain a control of all the dangerous waste, like sharp or polluted materials. In this way, an appreciable reduction is guaranteed in the impact on the atmosphere. (Author)

  15. Management of NORM Residues

    International Nuclear Information System (INIS)

    The IAEA attaches great importance to the dissemination of information that can assist Member States in the development, implementation, maintenance and continuous improvement of systems, programmes and activities that support the nuclear fuel cycle and nuclear applications, and that address the legacy of past practices and accidents. However, radioactive residues are found not only in nuclear fuel cycle activities, but also in a range of other industrial activities, including: - Mining and milling of metalliferous and non-metallic ores; - Production of non-nuclear fuels, including coal, oil and gas; - Extraction and purification of water (e.g. in the generation of geothermal energy, as drinking and industrial process water; in paper and pulp manufacturing processes); - Production of industrial minerals, including phosphate, clay and building materials; - Use of radionuclides, such as thorium, for properties other than their radioactivity. Naturally occurring radioactive material (NORM) may lead to exposures at some stage of these processes and in the use or reuse of products, residues or wastes. Several IAEA publications address NORM issues with a special focus on some of the more relevant industrial operations. This publication attempts to provide guidance on managing residues arising from different NORM type industries, and on pertinent residue management strategies and technologies, to help Member States gain perspectives on the management of NORM residues

    Full Text Available With the development of sound production and processing technologies, composers' private rooms stopped delimiting the boundaries of musical creativity, which started inhabiting recording studios instead. Here memory, traditionally entrusted to paper and to the silence of the musical text, met a technology that enabled to record sounds directly, thus achieving the acoustic fulfilment of the composer's thought. The crystalline abstraction of musical notation gave way to a world of sounds submerged in noise as well as in human and technological indeterminacy: it is a world that requires specific control strategies and direct confrontation with performance practices and listening within a complex system. Composers were tossed into this system, becoming performers and active observers of their own work. Thus, the linearity of Shannon’s model of communication was altered. In his works on musical semiology, Jean-Jacques Nattiez had already modified the model from Sender -> Message -> Receiver to Poietic dimension -> Trace <- Esthesic dimension. The rise of the composer as an active observer requires a new transformation of the model of communication, creating a continuous feedback between the different elements. This feedback will often involve the listener as well. The electronic music work can therefore be seen as a self-organizing system that includes in itself the electronic devices as well as the human factor that operates them. In this system, compositional models are the invariants that vouch for the identity and recognisability of the work.

    Full Text Available Campos rupestres are rare and endangered ecosystems that accommodate a species-rich flora with a high degree of endemism. Here, we make available a dataset from phytosociological surveys carried out in the Itacolomi State Park, Minas Gerais, southeastern Brazil. All species in a total of 30 plots of 10 x 10 m from two study sites were sampled. Their cardinality, a combination of cover and abundance, was estimated. Altogether, we registered occurrences from 161 different taxa from 114 genera and 47 families. The families with the most species were Poaceae and Asteraceae, followed by Cyperaceae. Abiotic descriptions, including soil properties such as type, acidity, nutrient or aluminum availability, cation exchange capacity, and saturation of bases, as well as the percentage of rocky outcrops and the mean inclination for each plot, are given. This dataset provides unique insights into the campo rupestre vegetation, its specific environment and the distribution of its diversity.

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

    Because neutrons can penetrate distances of up to 50 mm in most engineering materials, this makes them unique for establishing residual-stress distributions non-destructively. D1A is particularly suited for through-surface measurements as it does not suffer from instrumental surface aberrations commonly found on multidetector instruments, while D20 is best for fast internal-strain scanning. Two examples for residual-stress measurements in a shot-peened material, and in a weld are presented to demonstrate the attractive features of both instruments. (author)

    OpenAIRE

    Suwa, Tatsuo

    2003-01-01

    If we have a finite number of sections of a complex vector bundle $E$ over a manifold $M$ , certain Chern classes of $E$ are localized at the singular set $S$ , i.e., the set of points where the sections fail to be linearly independent. When $S$ is compact, the localizations define the residues at each connected component of $S$ by the Alexander duality. If $M$ itself is compact, the sum of the residues is equal to the Poincaré dual of the corresponding Chern class. This type of theory is als...

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

  6. Infrared inspection applied to offshore platforms: Petrobras experience at Campos Basin

    Science.gov (United States)

    Verdini, Edson A.; Veratti, Attilio B.

    2002-03-01

    Bacia de Campos (Rio de Janeiro - Brazil) is one of the biggest offshore petroleum fields in the world today. In June 2001, Bacia de Campos, having more than 490 oil wells, 34 offshore platforms and 7 modified ships in operation, reached 1,3 million barrels/day. If compared to OPEP countries only nine of them got an average production higher than 1 million barrels/day in 2000, which means it can be placed on the 10th position in the rank of oil producers. In this context this work aims not only to show the results achieved within the introduction of thermographic inspections in offshore oil production (platforms and ships), but also the financial results (ROI - Return of Investment) considering the use of this particular technique. Bacia de Campos got a ROI around 7 million dollars in the last 4 years, which means a hundred times higher than the total cost of thermographic services in the same period. As far as we know this is one of the best results already reported in the world. We also present the methodology applied to analyze thermal anomalies in electrical components and data management software, including advanced Digital Reports sent via Internet.

  13. Wood residues in Alberta

    International Nuclear Information System (INIS)

    The forest products industry is the third largest economic sector in Alberta, producing pulp and paper, dimensional lumber, paneling, and value added products, providing some 40,000 jobs . 'Value added' is a key component of expanding economic activity within the forest products sector. Wood residues can play a key role in obtaining more value from forest resources by providing new products, serving as feedstock to energy and chemical production, and playing a role in agriculture and land reclamation. One of the principal roles of the Forest Products Development Branch of the Alberta Economics Department is to encourage the development of the industry by creating new uses for these materials and developing awareness of the scope of the resource. Distances to markets, economic competition from conventional energy sources and coordination of research efforts are substantial barriers to further development that the Forest Products Development Branch has to face daily. Some notable successes in recent years are described. These include the Wood Residue Inventory and the Wood Residue Database that provide data on availability and principal location of wood residues, also a listing of contacts at the mills who produce the materials

    Full Text Available E. coli was submitted to a 5G electromagnetic field generated by a alternate 60 Hz voltage source. The differences on growth and glucose consume in control and exposed groups were evaluated using the non-parametric Mann-Whitney U-test. There was a significant difference in glucose consume and growth in E. coli after 8 hours of exposition to electromagnetic field. It can be concluded that electromagnetic field had a positive effect in consume of glucose and growth of E. coli. The cause of these results can be explained by an increasing of glucose entrance through membrane due to the stimulated transport system via Facility Diffusion or cyclotron resonance. The growth can be caused by shortening of lag phase and excitement of log phase.E. coli,em caldo glicosado,foi submetida a campo eletromagnético de intensidade 5G, gerado por fonte de tensão alternada de 60 Hz . Os crescimento e consumo de glicose foram avaliados através do teste não-paramétrico de Mann-Whitney para comparação de dois grupos. Após 8 h de exposição encontraram-se menor valor da glicose residual e maior turbidez nos tubos expostos ao campo evidenciando efeito positivo deste. A causa deste efeito no consumo da glicose pode ser pela estimulação de sistema de transporte de glicose, como a Difusão Facilitada ou por um tipo de fenômeno chamado ressonância ciclotrônica. O aumento do crescimento pode ser pelo encurtamento da lag phase e estimulação da log phase.

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

    In this study, four mixtures of LDPE post consumer with heavy gas from the Campos Basin, in different proportions, were subjected to pyrolysis in an inert atmosphere at 550 deg C. The pyrolytic liquids were characterized by gas chromatography coupled to mass spectrometry (GC/MS). Pyrolysis of pure diesel supplied large amounts of waste oil and only 4% in the range of diesel. On the other hand, the pyrolysis of LDPE mixture of diesel (at the ratio 1/0,5 m/m) provided 20% of light hydrocarbons with high production of pyrolytic oil (96%). The formation of high levels of paraffins and olefins in the range of diesel oil during the co-pyrolysis suggests a promising technology for recycling of plastic waste. (author)

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

    An integrated paleoecological, biostratigraphic and cyclostratigraphic study was carried out on sedimentary rhythm sequences in the Oligocene-Miocene of the Campos Basin, Brazil. The bio stratigraphic data combined with the spectral analysis performed on numerical data based on carbonate content variations of cores from well A, Campos Basin, reveal a periodicity related to the Milankovitch cycles. Benthic foraminiferal biofacies oscillations recognized in these cores have the same frequency and phase of long eccentricity cycles (400 Ka). Paleoceanographic changes (such as changes in ocean currents, water temperature and food supply) can modify the distribution and frequency patterns of foraminifera assemblages. However, the method used to interpret the biofacies, the geological context of the studied area and the proposed genetic model to explain the origin of these rhythmically patterned rocks, suggest that changes in foraminiferal biofacies are directly related to the paleobathymetry variations induced by glacio-eustatic oscillations of relative sea level . According to the proposed model, productivity-dilution cycles were instrumental in the origin of these marl-limestone couplets. During regressive phases, conditions were established to increase continental runoff to a bathyal setting. The increase of continental runoff with decrease of contribution of the main carbonate components led to the deposition of marlstone. During the transgressive phase, the relative reduction in clay input from continental sediments, favored a productivity growth of pelagic carbonate (calcareous nannofossil and planktonic foraminifera), which created conditions facilitating the deposition of limestone layers. The paleobathymetry oscillations, interpreted from the benthic foraminifera assemblage, and the formation of couplets, seems to be in phase with the transgressive-regressive cycles indicating a common cause to both processes.

La metodología para el tratamiento de los datos consistió en la conversión de los valores azimutales (variables circulares a datos numéricos mediante los senos directores con el fi n de evitar incompatibilidades en la medida del error. El análisis geoestadístico mostró que la variabilidad espacial de los datos son concurrentes con un efecto pepita de 0.0017 más un modelo exponencial con meseta igual a 0.0087 y rango de infl uencia de 7874 pies. La dirección del AEMH, estimada por el método de kriging ordinario de bloques, indicó que los valores AEMH varían entre 11º-65º, con un valor promedio de 34º, mientrasque el error de estimación varía entre 2° y 7°. Los resultados obtenidos permitieron diferenciar dos campos de orientación de esfuerzos mínimos horizontales: uno al norte, donde el AEMH tiende a valores inferiores a 40º y representan el 75% de los datos estimados; mientras que el 25% de los datos restantes, superan los valores obtenidos en el norte, debido probablemente a una mayor complejidad estructural de la zona.

    Many entrepreneurial businesses have attempted to create value based on the residual material streams of third parties. Based on ‘waste’ materials they designed products, around which they built their company. Such activities have the potential to yield sustainable products. Many of such companies remain in the more artistic domain, with relatively labor-intensive products, and small batch sizes. Moving beyond such small-scale activities would likely require a standardized innovation process....

    Full Text Available Various chemical agents are used during the whole production chain of milk and dairy products. Production of feedingstuffs is accompanied with pesticide usage, which may remain in environment, thus are transported through feeding into animals, animal products and finally in human organism. Preparation procedure and storage conditions of feed also influence on milk safety in the sense of mycotoxins entering into the food chain. Chemical agents are, on daily basis, used on dairy farms either as detergents or disinfections. The residuals of cleaning agents might remain in milk if the cleaning agents and its dosage are not performed adequately. Besides already mentioned agents, a great influence in milk production can bee seen through veterinary drugs usage, particularly antibacterial drugs (mastitis. Proper application of drugs and by following legal recommendation, a by-reactions can be avoided such as allergic reaction in humans, development of resisting bacteria or even undesirable influence on starter cultures in dairy products manufacture. The maximum residue limits, monitoring plan as well as sampling procedures are set up within the harmonization of Croatian and European legislation, in order to provide official control of residues in foodstuffs of animal origin.

    Full Text Available O campo científico da agropecuária é objeto do estudo que tem como objetivo investigar a construção da posição dominante ocupada pela Embrapa entre as entidades que se voltam para esse domínio do saber e trazer algumas inferências. Na consecução desses propósitos, optou-se por empregar métodos bibliométricos e sociométricos para uma leitura inscrita no paradigma positivista, considerando-o mais próximo aos cientistas que compõem o campo em evidência, convidando-os à reflexão e facilitando-a ao utilizar métodos de mesma natureza de suas pesquisas. As evidências coletadas parecem indicar que a projeção da Embrapa não restou explicada por mérito científico, o que implicou a necessidade de esquadrinhar explicações alternativas, quando se buscou em Bourdieu ferramental para a tarefa. Conclui-se que a Embrapa é central no campo estudado ao cuidar em projetar uma imagem, tão real quanto de fato, à medida que não é contestada além de reclamos não sistematizados e que dispensam dados objetivos - situação que por si mesma provoca outro questionamento, também encaminhado na pesquisa.

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

    Residue-residue contacts are very important in forming protein structure. In this work, we calculated the average probability of residue-residue contacts in 470 globular proteins and analyzed the distribution of contacts in the different interval of residues using Contacts of Structural Units (CSU) and Structural Classification (SCOP) software. It was found that the relationship between the average probability PL and the residue distance L for four structural classes of proteins could be expressed as lgPL=a+b×L, where a and b are coefficients. We also discussed the connection between two aspects of proteins which have equal array residue number and found that the distribution probability was stable (or un-stable) if the proteins had the same (or different) comnact (for examnle svnthase) in the same structural class.

    Full Text Available Synanthropic flies outstanding beside other flies due their relative abundance close to domestic animals and human population, to which they are able to cause myiasis or transmit pathogenic agents. As they're necrophagous they act as corpse decomposers and are useful in the forensic entomology in the post mortem interval determination. This study aimed to know flies diversity and abundance in Campo Grande, State of Mato Grosso do Sul. Captures were made weekly, utilizing three traps baited with decaying fish meat, from June of 2008 to May of 2009 in a remainder ciliary forest of the Embrapa's Cattle Beef Experimental Farm. The dipterans families that were considered and respectively number of collected specimens were: Calliphoridae (105,334; Muscidae (27,999; Sarcophagidae (21,083; Fanniidae (17,759 and Mesembrinellidae (305, totalizing 172,480 dipterous. To the local known species some Muscidae were increased as follows: Neomuscina atincticosta, Pseudoptilolepis elbida, Polietina orbitalis, Polietina flavithorax, Scutellomusca scutellaris, Graphomya analis and Morellia couriae.As moscas sinantrópicas se destacam pelo fato de serem relativamente abundantes junto à população humana e animais domésticos, podendo causar a estes miíases ou transmitir agentes patogênicos.

    Full Text Available This paper discusses the main items currently subject to recycling in Brazil to make a diagnosis on the management of domestic solid waste in the city of Campo Bom, in the catchment of the river valley of Sinos. The city of Campo Bom is neighboring the town of Novo Hamburgo. The survey is based on data supplied by the local administration COOLABORE (Cooperative Urban Cleaning and Construction. cooperative scavengers or environmental agents in the city and visits to Central treatment of household waste. We present all data related to waste management in the city both in its operational form for the results obtained. The results show large quantities of non-ferrous metals, ferrous metals, paper and cardboard and plastic and shows that paper and cardboard are more sensitive to seasonal generated by holiday periods, being mostly used in offices and businesses in relevant quantities. Since plastics are less sensitive and more for domestic use do not suffer sudden change in his generation during holiday periods. We analyzed the data from the first quarter of 2009.

    Full Text Available The objective of this work was to evaluate qualitative and quantitative leaf anatomical traits of Palicourea rigida Kunth. (Rubiaceae species occurring in the Brazilian Cerrado and Campo Rupestre ecosystems. Anatomical analysis was performed in fresh or fixed leaves processed with usual plant microtechnique. Leaves showed uniseriate epidermis in petiole and leaf blade which contains uniseriate nonglandular tricomes (tector type occurring only over the vascular bundles. Likewise, paracytic stomata were found only in abaxial side of the leaf surface. The mesophyll contains uniseriate palisade parenchyma and multiseriate spongy parenchyma (nine layers which showed cells with different morphology and size. Crystal idoblasts of different types were observed in both the petiole and leaf blade. Collateral vascular bundles were found both in the petiole and leaf blade. Leaf venation type was pinnate, campylodromous or brochydodromous. The micromorphometric analysis showed significant differences from plants of different environments for all leaf characteristics and Cerrado plants showed higher means for all evaluated traits. Therefore, the influence of environments may had modulated morphological responses in P. rigida, since no difference was found in the type or distribution of leaf tissues in Cerrado or Campo Rupestre.

    International Nuclear Information System (INIS)

    This work describes an event of unusually large mixing ratios of carbon monoxide, CO, observed during a typical rainy season time period in central Brazil, when concentrations are expected to be at low levels. CO measurements were performed in Campo Grande (20.02 deg. S; 54.5 deg. W), from July 2001 to October 2002, covering entire periods of the dry and wet seasons. From January to June, average CO was 131 parts per billion by volume (ppbv). During November/December, average CO is about 180 ppbv. On November 13, 521.9 and 565.6 ppbv were observed. It is shown that for this special event, in which there was practically no fire activity at or near the site, air parcels reaching the site were enriched with fire products from regions much further north, near the equatorial region, where the fire activity is delayed in time, compared to central Brazil. - Unusually high levels of CO occurred in Campo Grande, central Brazil in the rainy season

    The southern cattle fever tick, Rhipicephalus (Boophilus) microplus, is no doubt the most economically important ectoparasite of cattle globally. The inappropriate use of chemical acaricides has driven the evolution of resistance in populations of R. (B.) microplus. Anti-tick vaccines represent a technology that can be combined with acaricides in integrated control programs to mitigate the impact of R. (B.) microplus. The recombinant form of Bm86 antigen from the Campo Grande (rBm86-CG) strain of R. (B.) microplus was produced using the Pichiapastoris expression system to test its ability to immunoprotect cattle against tick infestation. Secretion of rBm86-CG by P. pastoris through the bioprocess reported here simplified purification of the antigen. A specific humoral immune response was detected by ELISA in vaccinated cattle. Immunoblot results revealed that polyclonal antibodies from vaccinated cattle recognized a protein in larval extracts with a molecular weight corresponding to Bm86. The rBm86-CG antigen showed 31% efficacy against the Campo Grande strain of R. (B.) microplus infesting vaccinated cattle. The rBm86-CG is an antigen that could be used in a polyvalent vaccine as part of an integrated program for the control of R. (B.) microplus in the region that includes Mato Grosso do Sul.

    The main objectives of this report are: To analyse the bioenergy potential of the Tanzanian agro-industries, with special emphasis on the Sisal industry, the largest producer of agro-industrial residues in Tanzania; and to upgrade the human capacity and research potential of the Applied Microbiology Unit at the University of Dar es Salaam, in order to ensure a scientific and technological support for future operation and implementation of biogas facilities and anaerobic water treatment systems. The experimental work on sisal residues contains the following issues: Optimal reactor set-up and performance; Pre-treatment methods for treatment of fibre fraction in order to increase the methane yield; Evaluation of the requirement for nutrient addition; Evaluation of the potential for bioethanol production from sisal bulbs. The processing of sisal leaves into dry fibres (decortication) has traditionally been done by the wet processing method, which consumes considerable quantities of water and produces large quantities of waste water. The Tanzania Sisal Authority (TSA) is now developing a dry decortication method, which consumes less water and produces a waste product with 12-15% TS, which is feasible for treatment in CSTR systems (Continously Stirred Tank Reactors).

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

    As in geothermal fields around the world, at Cerro Prieto geothermal field, Baja California, former exploratory and production wells are used to inject residual brine. Since the 1980s, studies and activities have been carried out to find ways to recharge the reservoir and dispose of brine without harming the environment or underground aquifers. These include infiltration and cold-and-hot injection. Some of the studies are presented here, including analyses of litho-facies; core samples; pressure, temperature and spinner logs; well tests and injection rates-plus some studies on the shallow aquifer. All have been useful in fulfilling requirements made by environmental authorities. Because injection rates constantly decrease due to formation damage, it is proposed an additional technique be used to reduce such damages and prolong the lifetime of cold-and-hot injection wells-while ensuring the environment and shallow aquifers are not affected. [Spanish] Al igual que en diversos campos geotermicos en el mundo, en el de Cerro Prieto, Baja California se han utilizado tanto pozos inyectores perforados ex profeso como antiguos pozos exploratorios y productores para inyectar el fluido residual al subsuelo.

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

    Amber from the Campo La Granja mine in Chiapas, Mexico, is distinct from other sources of amber in Chiapas. Campo La Granja amber has distinct layers created by successive flows of resin with thin layers of sand on most surfaces. Aquatic and semi-aquatic arthropods are commonly found. Together these pieces of evidence suggest an estuarine environment similar to modern mangrove communities. The aquatic crustaceans are the most intriguing aspect of the biota. A large number of ostracods have been found in the amber-many with their carapaces open, suggesting that they were alive and submerged in water at the time of entombment. The only known examples of brachyuran crabs preserved in amber are found in the Campo La Granja amber. Amphipods, copepods, isopods, and tanaids are also members of the crustacean fauna preserved in amber.

    Lilienkamp, R. H.

    1972-01-01

    A technique which employs known gas mixtures to calibrate the residual gas analyzer (RGA) is described. The mass spectra from the RGA are recorded for each gas mixture. This mass spectra data and the mixture composition data each form a matrix. From the two matrices the calibration matrix may be computed. The matrix mathematics requires the number of calibration gas mixtures be equal to or greater than the number of gases included in the calibration. This technique was evaluated using a mathematical model of an RGA to generate the mass spectra. This model included shot noise errors in the mass spectra. Errors in the gas concentrations were also included in the valuation. The effects of these errors was studied by varying their magnitudes and comparing the resulting calibrations. Several methods of evaluating an actual calibration are presented. The effects of the number of gases in then, the composition of the calibration mixture, and the number of mixtures used are discussed.

    Full Text Available É sabido que contar histórias é uma forma de comunicação humana que se estende aos dias de hoje. No entanto, tal prática se vê furtivamente ameaçada pelo desprendimento dos valores culturais tradicionais ante o florescer midiático. Objetivo: O presente trabalho postula o resgate da prática da contação de histórias no seio da comunidade rural de Jatobá, município de Janaúba/MG, através de um plano de intervenção pedagógico, como forma de valorizar as tradições e saberes do campo. Metodologia: Através de procedimentos de campo, foram avaliadas as perspectivas da tradição oral, partindo dos moradores mais antigos da localidade em cruzamento de dados com estudantes da escola local. Foi acionada uma entrevista para o primeiro grupo e um questionário para o segundo, buscando diagnosticar e refletir mais profundamente a realidade da tradição. Resultados: Evidenciou-se que a contação de histórias perde espaço no campo. As novas gerações têm pouco comprometimento e conhecimento das tradições e irrefletidamente se desconectam do núcleo cultural identitário de seu povo. A escola tem o papel de ressignificadora de práticas no resgate do berço cultural local. Considerações finais: A narrativa de histórias é uma atividade de potencial pedagógico inestimável, porém se vê em risco de desaparecimento, cumpre o ofício de seu resgate que se concatena ao resgate cultural e identitário de um povo e ao resgate do próprio indivíduo em seus manifestações e memória.

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

    1991-01-01

    A series of controlled experiments were conducted to determine the significance of crop residues or stubble in estimating the emission of the underlying soil. Observations using truck-mounted L and C band passive microwave radiometers showed that for dry wheat and soybeans the dry residue caused negligible attenuation of the background emission. Green residues, with water contents typical of standing crops, did have a significant effect on the background emission. Results for these green residues also indicated that extremes in plant structure, as created using parallel and perpendicular stalk orientations, can cause very large differences in the degree of attenuation.

    This paper will refer briefly to some key aspects considered for the design of an Electrically Heated Pipe-in-Pipe- EHPIP system integrated to an Electric Submersible Pump-ESP, to be located at 1800 m water depth in the Campos Basin. In this system, under normal operation the well will be producing through the ESP and in case of long well shut in and during well restart up, a percentage of the electrical power will be delivered to heat the PIP system. The electrical system will have a common sub sea power cable and an Electrical Switch Module, to switch power alternatively to the heating system or to the pump. The systems will not operate simultaneously. (author)

    2011-11-01

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

    2003-04-01

    Within the framework of the program Global Land Ice Measurements from Space (GLIMS) a glacier inventory of the Peninsula Muñoz Gamero in the southernmost Andes of Chile (53°S) has been generated using aerial photopgrahy and Landsat Thematic Mapper imagery. The Peninsula is partly covered by the ice cap of the Gran Campo Nevado (GCN), including several outlet glaciers plus some minor glaciers and firn fields. All together the ice covered areas sum up to 260 km2. GCN forms the only major ice body between the Southern Patagonia Icefield and the Strait of Magallan. Its almost unique location in a zone affected year-round by the westerlies makes it a region of key interest in terms of glacier and climate change studies of the west-wind zone of the Southern Hemisphere. A digital elevation model (DEM) was created for the area, using aerial imagery from 1942, 1984, and 1998 and a Chilean topographic map (1: 100 000). All information was incorporated into a GIS together with satellite imagery from 1986 and 2001. Delineation of glacier inflow from the central plateau of Gran Campo Nevado was accomplished using an automatic module for watershed delineation within the GIS. The GIS served to outline the extent of the present glaciation of the peninsula, as well as to evaluate the derived historic information. The comparison of historic and recent imagery reveals a dramatic glacier retreat during the last 60 years. Some of the outlet glaciers lost more than 20% of their total area during this period. In February and March 2000 a automatic weather station (AWS) was run on a nameless outlet glacier, inofficially Glaciar Lengua, of the Gran Campo Nevado Ice Cap. From the computed energy balance, it was possible to derive degree-day factors for the Glaciar Lengua. With data from the nearby AWS at fjord coast (Bahia Bahamondes) we computed ablation for the summer seasons of 1999/2000, 2000/2001 and 2001/2002. Ablation at 450 m a.s.l. sums up to about 7 m in 1999/2000, 5.5 m in 2000

    Camposrupestres are rare and endangered ecosystems that accommodate a species-rich flora with a high degree of endemism. Here, we make available a dataset from phytosociological surveys carried out in the Itacolomi State Park, Minas Gerais, southeastern Brazil. All species in a total of 30 plots of 10 x 10 m from two study sites were sampled. Their cardinality, a combination of cover and abundance, was estimated. Altogether, we registered occurrences from 161 different taxa from 114 genera and 47 families. The families with the most species were Poaceae and Asteraceae, followed by Cyperaceae. Abiotic descriptions, including soil properties such as type, acidity, nutrient or aluminum availability, cation exchange capacity, and saturation of bases, as well as the percentage of rocky outcrops and the mean inclination for each plot, are given. This dataset provides unique insights into the campo rupestre vegetation, its specific environment and the distribution of its diversity. PMID:25829858

  8. Geologic and geomorphologic controls of the kaolin deposits of Campo Alegre basin (SC-Brazil)

    International Nuclear Information System (INIS)

    The most important kaolin deposits from Campo Alegre region (S C) were formed by the conjunction of at least one hydrothermal phase followed by many others weathering, supergenic, phases. Possibly deposits formed by only one of these processes exist, but these deposits shall be small and smaller than those mined today. Besides kaolinization, illitization/muscovitization and silicification, hydrothermalism also generated pyritized and propilitized zones, with quartz + chlorite. Together, hipogenic alterations related to kaolin deposits are very similar to alterations of high sulfidation epigenetic volcanogenic gold deposits. Most part of the biggest kaolin mines from the southern part of Campo Alegre Basin are distributed along a 13 Km long and 0,5 Km width bent zone that is parallel to structural alignments that point out the eastern Basin border. This zone was originated by deformation that has inclined and broken rocks, generating a fault system alongside and parallel to structural lineaments. This fault system has made possible the ascent of hydrothermal hot aqueous fluids and of diqueform intrusions that caused hydrothermalism genetically related to kaolin deposits. Gamma spectrometry may indicate hydro thermalized zones. Although the potassium equivalent rock contents, derived from aerial gamma spectrometry of the mine regions, varies from a minimum of 2,07% to a maximum of 3,78%, 17 of the 20 mines are on high grade regions, with equivalent potassium contents grater than 3,04% and lower than 3,58%. The 'F factor' ((K.U)/Th) seems to indicate hydro thermalized zones better than potassium equivalent rock contents. Practically all the biggest mines on region are placed where 'F factor' is large, bigger than 10,05% and lower than 13,70%. The biggest mines are restricted to regions with altitudes between 950 and 1060 m. The average altitude of 23 mines is 1012,1+-13,8 m. This zone agrees with an ancient peneplane that makes possible the development of the intense

  10. Evaluation of residue-residue contact predictions in CASP9

    KAUST Repository

    Monastyrskyy, Bohdan

    2011-01-01

    This work presents the results of the assessment of the intramolecular residue-residue contact predictions submitted to CASP9. The methodology for the assessment does not differ from that used in previous CASPs, with two basic evaluation measures being the precision in recognizing contacts and the difference between the distribution of distances in the subset of predicted contact pairs versus all pairs of residues in the structure. The emphasis is placed on the prediction of long-range contacts (i.e., contacts between residues separated by at least 24 residues along sequence) in target proteins that cannot be easily modeled by homology. Although there is considerable activity in the field, the current analysis reports no discernable progress since CASP8.

  11. On tide-induced lagrangian residual current and residual transport: 1. Lagrangian residual current

    Science.gov (United States)

    Feng, Shizuo; Cheng, Ralph T.; Pangen, Xi

    1986-01-01

    Residual currents in tidal estuaries and coastal embayments have been recognized as fundamental factors which affect the long-term transport processes. It has been pointed out by previous studies that it is more relevant to use a Lagrangian mean velocity than an Eulerian mean velocity to determine the movements of water masses. Under weakly nonlinear approximation, the parameter k, which is the ratio of the net displacement of a labeled water mass in one tidal cycle to the tidal excursion, is assumed to be small. Solutions for tides, tidal current, and residual current have been considered for two-dimensional, barotropic estuaries and coastal seas. Particular attention has been paid to the distinction between the Lagrangian and Eulerian residual currents. When k is small, the first-order Lagrangian residual is shown to be the sum of the Eulerian residual current and the Stokes drift. The Lagrangian residual drift velocity or the second-order Lagrangian residual current has been shown to be dependent on the phase of tidal current. The Lagrangian drift velocity is induced by nonlinear interactions between tides, tidal currents, and the first-order residual currents, and it takes the form of an ellipse on a hodograph plane. Several examples are given to further demonstrate the unique properties of the Lagrangian residual current.

  17. Statistical inference on residual life

    CERN Document Server

    Jeong, Jong-Hyeon

    2014-01-01

    This is a monograph on the concept of residual life, which is an alternative summary measure of time-to-event data, or survival data. The mean residual life has been used for many years under the name of life expectancy, so it is a natural concept for summarizing survival or reliability data. It is also more interpretable than the popular hazard function, especially for communications between patients and physicians regarding the efficacy of a new drug in the medical field. This book reviews existing statistical methods to infer the residual life distribution. The review and comparison includes existing inference methods for mean and median, or quantile, residual life analysis through medical data examples. The concept of the residual life is also extended to competing risks analysis. The targeted audience includes biostatisticians, graduate students, and PhD (bio)statisticians. Knowledge in survival analysis at an introductory graduate level is advisable prior to reading this book.

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

  19. Residual stresses in welded structures

    International Nuclear Information System (INIS)

    The nature of residual stresses in welded structures is discussed in terms of their magnitude, directionality, spatial distribution, range and variability. The effects of the following factors on the residual stresses are considered: material properties, material manufacture, structural geometry, fabrication procedure, welding procedure, post-weld treatments and service conditions. Examples are given of residual stress distributions in plate butt welds, circumferential butt welds and weld cladding. These illustrate the different magnitudes and distributions of residual stress that can be found in different joint geometries, and demonstrate the effects of the mechanical, thermal and metallurgical properties of the constituent materials and the sensitivity of residual stresses to pass sequence and to the restraints applied during welding. Further examples for the common case of circumferential butt welds in pipes and pressure vessels are used to illustrate the extent of residual stresses as a function of distance from the weld and the effects of post-weld heat treatment. Measurements or analytical predictions of residual stresses are often subject to significant scatter or variability. This scatter may be due to systematic factors such as variability in measurement location or material properties, or to experimental error in measured data, erroneous assumptions in analytical modelling or unknown factors such as pre-existing residual stresses, inadequately documented welding or fabrication procedures or unrecorded local repairs. Improved prediction and reduction of uncertainty of residual stresses will require better recording of the whole manufacturing and service history of the welded structure and its component materials and better understanding and analysis of the many processes that may affect the residual stresses

  1. Respuesta de geófonos a campos electromagnéticos

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

Con la técnica de reconocimiento de patrones se observó que el riesgo sanitario era de igual modo mayor en los transmisores de televisión del oeste de la ciudad, en los emisores de frecuencia modulada del centro y en una de las frecuencias de radar del este de la ciudad, se hallaron múltiples edificaciones civiles en áreas de presunta restricción. El riesgo sería mínimo en las emisiones de ondas medias. Los valores que resultan de la situación real y los valores medidos indican que en ningún momento llega a transgredirse el nivel permisible de campo para la salud humana.

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

    Full Text Available Normal 0 21 false false false PT-BR X-NONE X-NONE O presente artigo, de caráter ensaístico, visa a contribuir com reflexões sobre modernidade, turismo e campo social sociais no Estado de Alagoas - Brasil. Utilizando o referencial de autores como Giddens (2001, Jameson (2002 e Harvey (1992, dentre outros, sintetizaremos algumas características das transições socioculturais da modernidade para o atual estágio do modo de produção capitalista, período que muitos têm considerado como a “pós-modernidade”. Posteriormente, empreenderemos breve descrição crítica acerca do atual modelo de turistificação no Estado, com base nos conceitos de Habitus e Campo Social, de Pierre Bourdieu. Conclui-se que o turismo em Alagoas está ancorado em roteiros que, em sua dominância, têm se consolidado sob os enunciados de Sol e Mar, tendência natural do turismo de massa que ocorre nas regiões intertropicais do mundo inteiro, em caso mais especifico, no Nordeste Brasileiro, e que também sofre direta influência da formação histórica de uma cultura de alheamento às potencialidades dos patrimônios identitários locais. /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Tabela normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-qformat:yes; mso-style-parent:""; mso-padding-alt:0cm 5.4pt 0cm 5.4pt; mso-para-margin:0cm; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:11.0pt; font-family:"Calibri","sans-serif"; mso-ascii-font-family:Calibri; mso-ascii-theme-font:minor-latin; mso-fareast-font-family:"Times New Roman"; mso-fareast-theme-font:minor-fareast; mso-hansi-font-family:Calibri; mso-hansi-theme-font:minor-latin; mso-bidi-font-family:"Times New Roman"; mso-bidi-theme-font:minor-bidi;}

    Full Text Available El condicionamiento clásico, lejos de tener una clara y única definición, se presenta en la literatura psicológica básica bajo múltiples conceptos basados en diferentes corrientes epistemológicas, tanto de la psicología como de las neurociencias. El objetivo principal de este artículo es presentar un análisis de la literatura acerca de condicionamiento clásico con el fin de discernir los conceptos, explícitos o implícitos, tanto en el campo básico como en el aplicado, el último principalmente en lo referido a las aplicaciones clínicas (psicoterapia. Se detectaron cuatro conceptos bien diferenciados de condicionamiento clásico: 1 Reflexológico (original pavloviano; 2 Conductista (liderado por B.F. Skinner; 3 Cognoscitivo (liderado por R.A. Rescorla; y 4 Neurobiológico (liderado por Eric R. Kandel. Los dos primeros se refieren más al condicionamiento clásico como método mientras que los dos últimos se refieren al condicionamiento clásico como proceso. En la literatura psicológica clínica los conceptos son más implícitos que explícitos; además tales conceptos son más de tipo reflexológico o conductista que cognoscitivo o neurobiológico. Las aplicaciones detectadas bajo esos conceptos han sido: las terapias aversivas y el recondicionamiento (bajo el concepto reflexológico, las terapias de exposición (bajo el concepto conductista, la formación de preferencias del consumidor hacia marcas publicitarias (bajo el concepto cognoscitivo y el condicionamiento del sistema inmunológico (bajo el concepto neurobiológico. A partir de este análisis conceptual se sugiere partir siempre de un ejercicio de identificación del concepto de condicionamiento clásico que se va a seguir ,con el fin de efectuar futuras intervenciones, clínicas o en cualquier otro campo, más precisas y efectivas.

    Full Text Available Este trabalho apresenta possibilidades de projeto em um vazio urbano na cidade de Campos dos Goytacazes. Os projetos tiveram como premissa princípios de sustentabilidade e ordenamento urbano, como, baixa ocupação do solo, mobilidade sustentável, densidade compatível com a estrutura urbana, distribuição equilibrada de áreas verdes e áreas institucionais, divisão em quadras convencionais e superquadras, hierarquia viária e definição de áreas de preservação. O objetivo do trabalho foi verificar o potencial de ocupação de um vazio urbano seguindo a Legislação de Parcelamento do Solo de Campos dos Goytacazes. Em relação à metodologia utilizada foram feitos estudos de caso, pesquisa da legislação urbanística e normas de acessibilidade, integração do sistema viário existente com o proposto. Foram definidos os tipos e tamanhos das vias, a divisão dos lotes nas quadras respeitando a Lei de Uso e Ocupação do Solo. A preservação do Parque Urbano definido pelo zoneamento municipal foi mantido e delimitado por novas vias. E para manter a continuidade viária do projeto, foi proposto um túnel passando por debaixo do parque com a preocupação de manter essa área preservada. Foi elaborado conceito com desenhos esquemáticos e posteriormente o projeto final em AutoCAD. O resultado segue a legislação urbanística e ambiental integrando o meio ambiente natural ao construído. Conclui-se que a área de estudo tem grande potencial de ocupação para projetos com características sustentáveis, assim destacamos que o poder público deve utilizar dos instrumentos da política urbana federal, como o parcelamento compulsório, para a disponibilização destas áreas que não atendem a função social da propriedade, para urbanização e ordenamento do território.

  12. Propoxur residues in cocoa beans

    International Nuclear Information System (INIS)

    Pod-bearing Amazon and Amelonado cocoa plants were sprayed with Unden 20% (propoxur, arprocarb, baygon) at the recommended rate of 210 g a.i./ha and twice the recommended rate at monthly intervals from July to October, 1976, and cured beans from the ripe pods analysed for propoxur residues by gas chromatography. In a radiotracer study with 14C-labelled propoxur, the effect of processing methods on residues and systemic uptake of propoxur from insecticide deposits on pod surfaces were also investigated. Residues did not exceed 0.03 ppm. There was no relationship between residues and harvesting time, cocoa type or rate of application. Contamination of beans with insecticide deposits on the pod surface during processing, and systemic uptake of insecticide from pod surfaces were negligible. (author)

  13. Nitrogen availability of biogas residues

    Energy Technology Data Exchange (ETDEWEB)

    El-Sayed Fouda, Sara

    2011-09-07

    The objectives of this study were to characterize biogas residues either unseparated or separated into a liquid and a solid phase from the fermentation of different substrates with respect to their N and C content. In addition, short and long term effects of the application of these biogas residues on the N availability and N utilization by ryegrass was investigated. It is concluded that unseparated or liquid separated biogas residues provide N at least corresponding to their ammonium content and that after the first fertilizer application the C{sub org}:N{sub org} ratio of the biogas residues was a crucial factor for the N availability. After long term application, the organic N accumulated in the soil leads to an increased release of N.

    Full Text Available O artigo analisa o processo de constituição de funerais em liturgias cívicas, destacando sua relação com outros fenômenos históricos, como a conformação dos imaginários nacionais, o processo de individualização moderno e as mudanças nas formas de lidar com a morte. Assim, pretende conjugar elementos que permitam refletir sobre a conformação de um campo específico de pesquisas, cuja potencialidade permanece ainda pouco explorada. Chamando a atenção para os limites das análises centradas apenas nos usos políticos e intencionais do passado, ressalta a importância de considerar as dimensões utópica e imaginária presentes nos rituais e festas cívicas, sugerindo a relevância de tal reflexão para pensar o próprio desenvolvimento da prática historiográfica.

    Full Text Available Este trabalho introduz uma discussão sobre a ação social no campo da cultura política buscando entender a capacidade de adesão dos indivíduos aos valores e normas que orientam uma sociedade democrática. Foca a análise na reciprocidade entre atores e sistemas de troca e entre estes e as instituições, considerando os valores culturais e o capital social. O pressuposto geral refere-se à tradição brasileira da ambigüidade dos valores nas trocas que regem os sistemas sociais na esfera pública e na privada, exacerbando ambivalências, paradoxos e formando um híbrido institucional entre o mundo formal e o informal. Analisa a questão em relação ao sentido da liberdade, da obrigação e da confiança na relação entre os direitos e deveres que configuram a identidade social e a participação política de cada um, na forma como se relacionam com as trocas e a reciprocidade na democracia brasileira.

Se pretende contribuir a una mejor comprensión de los significados de la seguridad alimentaria, específicamente sobre: riesgos en la alimentación habitual de las familias de bajos ingresos; cambios a largo plazo de su dieta y del contexto; así como de sus esfuerzos para proteger e inclusive mejorar la alimentación familiar. En el medio urbano, esas mujeres perciben riesgos principalmente en la calidad de los alimentos (food safety, mientras que en el medio rural los advierten tanto en el acceso a los alimentos (food security como en la baja calidad de los mismos. Descubrimos dos rasgos nuevos de la percepción de la seguridad alimentaria: el tiempo disponible del ama de casa urbana para cocinar y la continuidad en el campo de una cultura étnica con saberes y habilidades femeninas valiosas. Aún falta mucho por hacer para alcanzar los diferentes tipos de seguridad alimentaria, así como para contar con una democracia alimentaria plena, al igual que una evolución aceptable de México en el aspecto nutricional.

The surrounding area is used for soybeans cultivation, corn, cotton, and pasture. We examined biotic (heterotrophic bacteria and chlorophyll a and abiotic factors (precipitation, air and water temperature, electrical conductivity, dissolved oxygen, pH, turbidity, total phosphorus, nitrite, nitrate, and ammonia nitrogen at three sampling sites along the longitudinal axis of the water body, and at three depths (at the surface, the Secchi depth, and at the sediment-water interface. Samples were taken bimonthly during 2010. Spearman correlation analysis was used to examine the relationship between biotic and abiotic variables, and then principal components and cluster analyses were used to study the relationship between these factors and the variability observed among the various sampling sites, dam depths, and periods of observation. The analyses showed a strong correlation between factors such as rainfall, heterotrophic bacteria, conductivity, turbidity, and phosphorus, indicating the influence of seasonality in cultivated areas. It was observed that the variations between the sampling sites were more significant (p < 0.01 than in the water column for most of the variables, probably due to the particular characteristics of each sample point and its shallow water column.

    Full Text Available Observou-se alta contaminação bacteriana nos explantes de mamoeiro introduzidos in vitro, a partir de plantas matrizes desenvolvidas no campo, independentemente da época do ano em que se realizaram as coletas. O uso de desinfestantes superficiais, como álcool e hipoclorito de sódio, garantiram níveis aceitáveis de controle apenas para fungos, não para bactérias. A rifampicina, por tratamento de imersão ou introdução em meio de cultura, controlou satisfatoriamente as contaminações de caráter endofítico, obtendo-se 70% de explantes sadios, sem sinais de fitotoxicidade.High contamination by bacteria was observed in papaya tissue cuttings introduced in vitro from plants grown in the field, independent of the period of the year that samples were collected. The use of alcohol and sodium hypoclorite did not guarantee good bacteria control. Rifampicin, added as an immersion solution treatment or in the culture media, controlled the internal contamination of explants, without damaging the cuttings. Up to 70% of healthy tissue explants were obtained by the use of rifampicin.

Specifically, we sought to: a identify the variables which make up the image attributes of supermarkets and group them into factors, and b assess the impact of image attributes on consumer satisfaction. We conducted a quantitative study, which met quotas by region and city income class, among 400 individuals from Campo Grande, MS, southwest Brazil, who were responsible for purchasing supermarket products for their families. Exploratory Factor Analysis (EFA and Structural Equation Modeling were used for the data analysis. The results revealed that the attributes are grouped into five factors. The constructs “environment” and “promotions” were not considered significant in determining satisfaction, while the attributes “employees”, “product” and “price” had a positive effect on satisfaction, with the latter having the greatest impact. DOI: 10.5585/remark.v12i4.2561

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

Também foi constatada diferença estatística quanto ao fator que promoveria aumento de consumo de carne de pescado, sendo que homens consumiriam mais peixes se fossem mais fáceis de preparar, enquanto mulheres indicaram que a redução do preço permitiria aumento de consumo. O preço do quilograma de pescado considerado ideal pelos entrevistados seria entre R$2,01 e R$5,00. A maior parte dos entrevistados afirmou que não existe diferença quanto à preferência da origem do pescado.

    Full Text Available Los grandes campos de petróleo han jugado un papel fundamental como aporte de hidrocarburos en el mundo, pero la mayoría de ellos está en proceso de declinación. El macro yacimiento Cantarell ha sido el origen de importantes volúmenes de hidrocarburos y grandes beneficios para el país, pero a partir de 2004 inició su proceso de declinación que ha afectado la plataforma de producción de petróleo. Esta investigación estudia el conjunto de elementos que han incidido sobre el desempeño de ese macro yacimiento, los cuales son fundamentales para explicar su situación actual. Se concluye que la administración de Cantarell no fue la óptima durante los tres periodos característicos identificados, toda vez que se sujetó a determinaciones no técnicas, que incidieron en su declinación y en la serie de retos que está enfrentando, mismos que a su vez, podrían atenuarse con el empleo de tecnología.

    Full Text Available About 25% of the Brazilian population have some kind of deficiency, among them 50% are mental. Brazilian situation isaggravated due to poverty conditions, misery, malnutrition, need of basic sanitation, disinformation, and precarious healthattendance. It is esteem that 350 million people with deficiency are excluded of any kind of medical attendance. For themaintenance of a person that carries a deficiency, 12,452 dollars are spent annually. On the other hand, “per capita” annual costof primary prevention is 20 dollars and of secondary prevention is 600 dollars. Population does not have access to informationabout causes, prevention and deficient child attendance and demonstrates wrong information, superstition and fears about thissubject. Thus, this study aimed to detect factors that may contribute with the improvement of preventive actions. Data obtainedfrom studies carried out with 100 APAE Scholl students in Campo Mourão allowed to analyze some common characteristicsabout them. One of these characteristics was that from all of 100 students under analysis, 52 had relatives with some kind ofmental, sensorial or additive deficiency.

    Full Text Available A última década foi palco de importantes transformações no campo da Cooperação Internacional para o Desenvolvimento (CID. Nesse período, novos provedores - países em desenvolvimento, agentes privados e organizações civis - tornaram-se protagonistas no campo. Entre os "novos provedores", os países BRICS ocupam posição de destaque. Este artigo discute as transformações estruturais do campo da CID e, particularmente, os efeitos da emergência de novos provedores, como os BRICS, sobre as posições e as dinâmicas que caracterizam o campo. Pretende demonstrar que a emergência de "novos provedores" e de novas modalidades de cooperação internacional resultou no descentramento do campo da CID. Nesse contexto, abre-se um processo de reordenamento do campo no qual a arquitetura institucional da CID se torna palco de intensa disputa política entre doadores tradicionais e "novos provedores". O artigo analisa alguns aspectos centrais dessa disputa e sugere que o processo, em curso, de descentramento e reordenamento do campo da CID desestabilizou não apenas a posição ocupada pelos doadores tradicionais, como também a posição dos novos provedores.

  6. Evaluation of residue-residue contact prediction in CASP10

    We present the results of the assessment of the intramolecular residue-residue contact predictions from 26 prediction groups participating in the 10th round of the CASP experiment. The most recently developed direct coupling analysis methods did not take part in the experiment likely because they require a very deep sequence alignment not available for any of the 114 CASP10 targets. The performance of contact prediction methods was evaluated with the measures used in previous CASPs (i.e., prediction accuracy and the difference between the distribution of the predicted contacts and that of all pairs of residues in the target protein), as well as new measures, such as the Matthews correlation coefficient, the area under the precision-recall curve and the ranks of the first correctly and incorrectly predicted contact. We also evaluated the ability to detect interdomain contacts and tested whether the difficulty of predicting contacts depends upon the protein length and the depth of the family sequence alignment. The analyses were carried out on the target domains for which structural homologs did not exist or were difficult to identify. The evaluation was performed for all types of contacts (short, medium, and long-range), with emphasis placed on long-range contacts, i.e. those involving residues separated by at least 24 residues along the sequence. The assessment suggests that the best CASP10 contact prediction methods perform at approximately the same level, and comparably to those participating in CASP9.

  7. Study of chemical composition of sludges and scales from the oil production activities and correlation with natural radioactivity - case study: Campos Basin, Brazil

    International Nuclear Information System (INIS)

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

    The structural framework and tectonic evolution of the sedimentary basins along the eastern margin of the South American continent are closely associated with the tectonic framework and crustal heterogeneities inherited from the Precambrian basement. However, the role of NW-SE and NNW-SSE structures observed at the outcropping basement in Southeastern Brazil and its impact over the development of those basins have not been closely investigated. In the continental region adjacent to the Campos Basin, we described a geological feature with NNW-SSE orientation, named in this paper as the Alegre Fracture Zone (AFZ), which is observed in the onshore basement and can be projected to the offshore basin. The main goal of this work was to study this structural lineament and its influence on the tectonic evolution of the central portion of the Campos Basin and adjacent mainland. The onshore area was investigated through remote sensing data joint with field observations, and the offshore area was studied through the interpretation of 2-D seismic data calibrated by geophysical well logs. We concluded that the AFZ occurs in both onshore and offshore as a brittle deformation zone formed by multiple sets of fractures that originated in the Cambrian and were reactivated mainly as normal faults during the rift phase and in the Cenozoic. In the Campos Basin, the AFZ delimitates the western side of the Corvina-Parati Low, composing a complex fault system with the NE-SW faults and the NW-SE transfer faults.

    Full Text Available A guerra na Bósnia-Herzegóvina organizou territórios etnicamente e redefiniu as categorias étnico-nacionais - sérvia, croata e bosniac (muçulmana. Enquanto os soldados combatiam nas linhas de frente, inúmeras eram as atrocidades testemunhadas em outros campos de batalha: casas, vilas, cidades, campos de detenção e concentração e os campos de estupro. Faço neste artigo uma revisão da discussão acerca do estupro na guerra na Bósnia, como este pode ser visto como arma de guerra e um instrumento de limpeza étnica e de tentativa de extermínio.The war in Bosnia and Herzegovina ethnically organized territories and redefined the ethno-national categories and groups - Serbs, Croats and Bosnians (Muslims. Beside the battles between soldiers at the front lines, several atrocities used to happen in other fields: homes, villages, cities, detention places, concentration camps, and the rape camps. This article introduces the debate about the rapes that occurred during the war in Bosnia and the ways to understand them: as a war weapon, as an ethnic cleansing tool, as an attempt to extermination.

    Full Text Available Este artigo procura traçar um panorama do campo da fotografia profissional no Brasil desde o primeiro governo Vargas até o final do século XX. Nas décadas de 1930 e 1940, nova leva de fotógrafos estrangeiros se mudou para o país. Alguns ocuparam postos no governo federal e construíram a imagem fotográfica da Nação. Em meados do século, a maneira de se fazer fotografias para a imprensa sofreu profunda alteração e pela primeira vez um museu brasileiro expôs fotografias. A ditadura militar interferiu decisivamente na produção da indústria cultural. Os anos de 1970 foram marcados pela transformação no perfil profissional e do status dos fotógrafos, causados principalmente pela entrada no mercado de jovens saídos das universidades. Nesta mesma década foi criada uma instituição destinada a valorizar a fotografia brasileira em todas as suas dimensões: o Núcleo de Fotografia da Fundação Nacional de Arte. Finalmente, o campo da fotodocumentação recebeu um forte impulso com a criação de bolsas e de leis de incentivo que, ao lado de um aumento significativo do mercado consumidor de livros de fotografia, permitiu a multiplicação não só de trabalhos autorais, como também de publicações.This article draws an overview of the field of professional photography in Brazil since the first Vargas administration to the end of the Twentieth Century. In the 30.s and 40.s, a new host of photographers came to live in Brazil from various countries. Some of them took positions in the Federal Government and were responsible for building a photographical image of the Nation. In the middle of the Century, the technique to make photos for newspapers suffered a profound change and, for the first time, a Brazilian museum organized an exhibit of photographs. The military dictatorship decisively interfered in the cultural industry. The 70.s were marked by changes in the status and in the professional profile of photographers, brought about

  14. Petrochemical characteristics of Serra do Meio alkaline granite (Campo Alegre de Lourdes - Bahia State)

    International Nuclear Information System (INIS)

    The Serra do Meio granite outcrops near the town of Campo Alegre de Lourdes, north-northeast of Bahia State. The granite is intrusive into micachists, which are correlatives of the Salgueiro-Cachoeirinha Group (Early Proterozoic), during early to the syn-tectonic shear phase. The geological setting also comprises a phosphatic rock-bearing carbonatitic complex and gabbroid complexes with one of the main world resources of Fe-Ti-V. The granite mineralogical composition grades from Aegerine-augite alkali-feldspar granite/syenites to Leuco alcali-feldspar granite. The geochemical analysis shows SiO2-enrichment (67 to 76%), in alkalis (Na2+K2O, 7,5 to 12,5%), Nb (up to 680ppm), Zr (up to 2,390ppm), Y (up to 250ppm) e REE (up to 796ppm). The geochemical behaviour is peculiar to alkaline series, denoting a silica-oversaturated, potassium-rich, magma. The chondrite-normalized REE patterns display a first group with smooth slopes from the La to Lu, and a second one with negative slopes. Negative Eu anomalies are displayed in all the patterns. The first group is HREE-enriched, with low fractionation ratios. Samples with milonytic fabrics and higher fractionation ratios are related to the second group, suggesting the interaction of metassomatic fluids and the alkaline magma. Discriminant diagrams for Nb, Y and Rb, coupled with geophysical data, point to an intrusive granite in an extensional within a plate tectonic setting of attenuated continental crust. (author)

Se plantea que la mirada dominante en el tema ha puesto un énfasis exagerado en la idea de una apropiación defensiva del espacio, por sobre la necesidad de construir comunidades sanas e integradas. Se propone a continuación un marco teórico alternativo a lo anterior, la metodología de la Sintaxis Espacial planteada por Bill Hillier y colegas (1984 desde hace más de treinta años en Inglaterra. espués de introducir algunos conceptos del análisis confi guracional, se proponen dos aspectos conceptuales y metodológicos planteados por esta visión que podrían ayudar en el diseño de un hábitat residencial más seguro: la idea de la legibilidad de la trama, y la idea de los campos visuales. A continuación, se examinan estas ideas en un caso real, la comuna de Quilicura, localizada en la periferia de Santiago. Los resultados muestran que las herramientas propuestas en la Sintaxis Espacial permiten al arquitecto y planificador urbano, evaluar a priori distintas alternativas de diseño del hábitat, las que pueden ser decisivas al momento de mejorar la percepción de seguridad en el espacio residencial.

    Upwelling events observed from the years 2003 to 2011 were analyzed. Our focus was on the Abrolhos-Campos region (ACR, 15°S-23°S), which is located along the Brazilian Margin and influenced by a western boundary current, the Brazil Current (BC). Satellite sea surface temperature, National Centers for Environmental Prediction (NCEP) and Global Forecast System (GFS) wind data were used to complement the results of a high-resolution regional oceanic model to investigate the occurrence of and the mechanisms responsible for intense upwelling events in this region. These events were more frequent from 20°S to 23°S. Over 90% of the identified upwelling events were influenced by favorable wind stress. Surface Ekman transport was found to be more important for the region from Prado (17°S) to Marataízes (21°S), whereas upward Ekman pumping played a more important role from 22°S to 23°S. Current-driven upwelling processes associated with the location of the BC as well as its velocity and meso-scale activity were also analyzed. The results showed that these mechanisms are highly influenced by the local topography. Topographic effects exerted via the acceleration of the BC are more obvious in the southern ACR, while in the Prado region, BC cyclonic meanders tend to be more relevant. Moreover, eddy-driven upwelling increases in the southward direction after the passage of the Vitória-Trindade Ridge (20°S), an important submarine chain, which acts to constrain and modulate the southward flow of the BC.

Uma adaptação de processos de microeletrônica tradicional foi feita para a confecção desse dispositivo. O FET desenvolvido apresentou modulação por voltagem de porta Vg, mas operou mesmo em Vg=0. A corrente de dreno I D aumentou significativamente sob iluminação na região da radiação visível e infravermelho próximo, mostrando o caráter fotocondutor da POMA dopada e, portanto, do dispositivo. Um modelo teórico baseado nos mecanismos de condução eletrônica da POMA, e de efeitos de interface metal-polímero foi elaborado, ajustando-se muito bem aos resultados experimentais.ABSTRACT: A field effect transistor - FET made from poly(o-methoxyaniline (POMA, which is a conductive polymer, was developed. Several modifications were carried out to adapt the procedures generally used in traditional device developments. The characteristic of the FET produced was sensible to the gate modulation, but it operates even for V G = 0. The drain current I D enhanced under visible and near infrared radiation, showing the photoconductor character of POMA and, consequently, of the device. A theoretical model, based on the electronic properties of POMA and on the metal-polymer interface, was developed which is in good agreement with the experimental results.

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

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

  1. Actinide recovery from pyrochemical residues

    International Nuclear Information System (INIS)

    We demonstrated a new process for recovering plutonium and americium from pyrochemical waste. The method is based on chloride solution anion exchange at low acidity, or acidity that eliminates corrosive HCl fumes. Developmental experiments of the process flow chart concentrated on molten salt extraction (MSE) residues and gave >95% plutonium and >90% americium recovery. The recovered plutonium contained 62- from high-chloride low-acid solution. Americium and other metals are washed from the ion exchange column with lN HNO3-4.8M NaCl. After elution, plutonium is recovered by hydroxide precipitation, and americium is recovered by NaHCO3 precipitation. All filtrates from the process can be discardable as low-level contaminated waste. Production-scale experiments are in progress for MSE residues. Flow charts for actinide recovery from electro-refining and direct oxide reduction residues are presented and discussed

The polypropylene samples and gas-oil weresubmitted to the thermal co-pyrolysis in an inert atmosphere, varying the temperature and the amount of PP.The influence of the gas-oil was evaluated carrying the co-pyrolysis in the absence of PP. The pyrolysed liquidsproduced by this thermal treatment were characterized by modified gaseous chromatography in order toevaluate the yield in the range of distillation of diesel. As a result, the increase of PP amount lead to a reductionin the yield of the pyrolytic liquid and to an increase of the amount of solid generated. The effect of temperatureincrease showed an inverse result. The results show that plastic residue co-pyrolysys is a potential method forchemical recycling of plastic products.

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

  6. Peptide iodination on phenylalanine residues

    International Nuclear Information System (INIS)

    Peptide labelling with radioactive isotopes is always a compromise between peptide chemistry, labelling chemistry, and biological receptor tolerance. Therefore new ways for isotope introduction are always useful. The present contribution describes the introduction of iodine isotopes onto synthetic polypeptides by means of the Gattermann/ Sandmeyer reactions. Peptides containing the nitrophenylalanyl residue are reduced to the corresponding aminophenylalanyl, diazolized to the diazonium phenylalanyl peptide and converted to the iodophenylalanyl peptide in the presence of copper. Two examples are presented: angiotensin II and enkephalin. In both cases, the iodophenylalanyl residue is well accepted by the biological target. (author). 13 refs.; 4 figs

  17. Pyrotechnic reaction residue particle analysis.

    2006-03-01

    Pyrotechnic reaction residue particle (PRRP) production, sampling and analysis are all very similar to that for primer gunshot residue. In both cases, the preferred method of analysis uses scanning electron microscopy to locate suspect particles and then uses energy dispersive x-ray spectroscopy to characterize the particle's constituent chemical elements. There are relatively few times when standard micro-analytical chemistry performed on pyrotechnic residues may not provide sufficient information for forensic investigators. However, on those occasions, PRRP analysis provides a greatly improved ability to discriminate between materials of pyrotechnic origin and other unrelated substances also present. The greater specificity of PRRP analysis is the result of its analyzing a large number of individual micron-sized particles, rather than producing only a single integrated result such as produced using standard micro-analytical chemistry. For example, PRRP analyses are used to demonstrate its ability to successfully (1) discriminate between pyrotechnic residues and unrelated background contamination, (2) identify that two different pyrotechnic compositions had previously been exploded within the same device, and (3) establish the chronology of an incident involving two separate and closely occurring explosions.

    Full Text Available Esta pesquisa procura compreender um fenômeno aparentemente comum: o sonho de muitos moradores urbanos em ter uma casa no campo. A investigação é feita junto aos leitores da revista Globo Rural, uma publicação especializada em atividades agrícolas. São assinantes que residem na cidade de São Paulo e não possuem nenhum tipo de propriedade no meio rural. O propósito deste estudo é tentar apreender os movimentos desse imaginário, contribuindo para o debate das conexões entre campo e cidade e para o entendimento da interação entre sujeitos e produtos culturais simbólicos, no cotidiano urbano contemporâneo. Diante da complexa relação do homem com a natureza e da condição histórica vivida numa metrópole nesta virada de século, percebe-se que, ao sonhar com a casa no campo, os leitores urbanos da revista não apenas se voltam de maneira saudosa para o passado rural. No tempo presente, eles tecem uma crítica profunda ao modelo civilizatório da urbanidade da metrópole e, olhando para frente, imaginam um futuro melhor fora da cidade, no meio rural, mais perto das coisas da natureza, num lugar mais solidário, longe da violência, do trânsito pesado, da poluição e com mais qualidade de vida.

    The sleeping sickness focus of Campo lies along the Atlantic coast and extends along the Ntem River, which constitutes the Cameroonian and Equatorial Guinean border. It is a hypo-endemic focus with the disease prevalence varying from 0.3 to 0.86% during the last few decades. Investigations on animal reservoirs revealed a prevalence of Trypanosoma brucei gambiense of 0.6% in wild animals and 4.83% in domestic animals of this focus. From 2001 to 2012, about 19 931 tsetse were collected in this focus and five tsetse species including Glossina palpalis palpalis, G. pallicera, G. nigrofusca, G. tabaniformis and G. caliginea were identified. The analysis of blood meals of these flies showed that they feed on human, pig, goat, sheep, and wild animals such as antelope, duiker, wild pig, turtle and snake. The percentage of blood meals taken on these hosts varies according to sampling periods. For instance, 6.8% of blood meals from pig were reported in 2004 and 22% in 2008. This variation is subjected to considerable evolutions because the Campo HAT focus is submitted to socio-economic mutations including the reopening of a new wood company, the construction of autonomous port at "Kribi" as well as the dam at "Memve ele". These activities will bring more that 3000 inhabitants around Campo and induce the deforestation for the implementation of farmlands as well as breeding of domestic animals. Such mutations have impacts on the transmission and the epidemiology of sleeping sickness due to the modification of the fauna composition, the nutritional behavior of tsetse, the zoophilic/anthropophilic index. To achieve the elimination goal in the sleeping sickness focus of Campo, we report in this paper the current epidemiological situation of the disease, the research findings of the last decades notably on the population genetics of trypanosomes, the modifications of nutritional behavior of tsetse, the prevalence of T. b. gambiense in humans, domestic and wild animals.

    2011-04-01

    Full Text Available El sistema defensivo contemporáneo del Campo de Gibraltar es un plan de elaborado por el Estado Mayor de Franco antes del estallido de la Segunda Guerra Mundial. Se basa en más de quinientos fortines de hormigón, construidos desde mayo de 1939 y durante el conflicto mundial, a partir del temor a una invasión anglo-francesa procedente de Gibraltar. Ciertas informaciones del espionaje militar, con escasa base, condujeron al inicio de la fortificación del istmo de Gibraltar, extendiendo sus flancos desde la desembocadura del río Guadiaro hasta las playas de Conil. Es un proyecto diferente del plan de artillado del Estrecho que aborda, inmediatamente después, la Comisión de Fortificación de la Frontera Sur del general Jevenois. Aunque el sistema presenta claras influencias formales europeas, continúa principios tácticos ensayados ampliamente en la Guerra Civil Española.Palabras clave: Campo de Gibraltar, Fortín, General Jevenois, Sistema defensivo contemporáneo, Segunda Guerra Mundial, Comisión de Fortificación de la Frontera Sur___________________________Abstract:The contemporary defensive system in the Campo de Gibraltar was planned by General Franco before the Second World War outbreak. It consists of over five thousand bunkers which were built between May 1939 and the end of the war, due to the fear of a British-French attack from Gibraltar. This unfounded information, provided by the military intelligence services, led to the building of the aforementioned defensive system, starting in the isthmus of Gibraltar and occupying the area between River Guadiaro and the beaches of Conil. This plan is different from the Strait artillery plan which was developed just after the aforementioned one by General Jenevois' Comisión de Fortificación de la Frontera Sur (South Border Fortification Comission. Although this defence system is clearly influenced by the European trend, it is based on the tactics developed during the Spanish Civil War

    Mitrinović, Dragoslav S

    1993-01-01

    Volume 1, i. e. the monograph The Cauchy Method of Residues - Theory and Applications published by D. Reidel Publishing Company in 1984 is the only book that covers all known applications of the calculus of residues. They range from the theory of equations, theory of numbers, matrix analysis, evaluation of real definite integrals, summation of finite and infinite series, expansions of functions into infinite series and products, ordinary and partial differential equations, mathematical and theoretical physics, to the calculus of finite differences and difference equations. The appearance of Volume 1 was acknowledged by the mathematical community. Favourable reviews and many private communications encouraged the authors to continue their work, the result being the present book, Volume 2, a sequel to Volume 1. We mention that Volume 1 is a revised, extended and updated translation of the book Cauchyjev raeun ostataka sa primenama published in Serbian by Nau~na knjiga, Belgrade in 1978, whereas the greater part ...

  6. Residual intersections and some applications

    CERN Document Server

    Wu, X

    1994-01-01

    We give a new residual intersection decomposition for the refined intersection products of Fulton-MacPherson. Our formula refines the celebrated residual intersection formula of Fulton, Kleiman, Laksov, and MacPherson. The new decomposition is more likely to be compatible with the canonical decomposition of the intersection products and each term in the decomposition thus has simple geometric meaning. Our study is motivated by its applications to some geometric problems. In particular, we use the decomposition to find the distribution of limiting linear subspaces in degenerations of hypersurfaces. A family of identities for characteristic classes of vector bundles is also obtained as another consequence. This paper will appear in Duke Math. Jour.

  7. Calcination/dissolution residue treatment

    International Nuclear Information System (INIS)

    Currently, high-level wastes are stored underground in steel-lined tanks at the Hanford site. Current plans call for the chemical pretreatment of these wastes before their immobilization in stable glass waste forms. One candidate pretreatment approach, calcination/dissolution, performs an alkaline fusion of the waste and creates a high-level/low-level partition based on the aqueous solubilities of the components of the product calcine. Literature and laboratory studies were conducted with the goal of finding a residue treatment technology that would decrease the quantity of high-level waste glass required following calcination/dissolution waste processing. Four elements, Fe, Ni, Bi, and U, postulated to be present in the high-level residue fraction were identified as being key to the quantity of high-level glass formed. Laboratory tests of the candidate technologies with simulant high-level residues showed reductive roasting followed by carbonyl volatilization to be successful in removing Fe, Ni, and Bi. Subsequent bench-scale tests on residues from calcination/dissolution processing of genuine Hanford Site tank waste showed Fe was separated with radioelement decontamination factors of 70 to 1,000 times with respect to total alpha activity. Thermodynamic analyses of the calcination of five typical Hanford Site tank waste compositions also were performed. The analyses showed sodium hydroxide to be the sole molten component in the waste calcine and emphasized the requirement for waste blending if fluid calcines are to be achieved. Other calcine phases identified in the thermodynamic analysis indicate the significant thermal reconstitution accomplished in calcination

    The U.S. Nuclear Regulatory Commission development of criteria for release of facilities and sites for unrestricted use following decommissioning is described. Residual activity limits for both materials and soil are covered. The objectives are: small risk of exposure, consistency with relevant existing standards, and feasibility of demonstration of compliance by measurement. Specific aspects discussed related to establishment of limits are: appropriate risk and dose limits, identification of radionuclides to be considered, dose assessment methodology, and confirmatory measurements

  9. Geotechnical characteristics of residual soils

    Energy Technology Data Exchange (ETDEWEB)

    Townsend, F.C.

    1985-01-01

    Residual soils are products of chemical weathering and thus their characteristics are dependent upon environmental factors of climate, parent material, topography and drainage, and age. These conditions are optimized in the tropics where well-drained regions produce reddish lateritic soils rich in iron and aluminum sesquioxides and kaolinitic clays. Conversely, poorly drained areas tend towards montmorillonitic expansive black clays. Andosols develop over volcanic ash and rock regions and are rich in allophane (amorphous silica) and metastable halloysite. The geological origins greatly affect the resulting engineering characteristics. Both lateritic soils and andosols are susceptible to property changes upon drying, and exhibit compaction and strength properties not indicative of their classification limits. Both soils have been used successfully in earth dam construction, but attention must be given to seepage control through the weathered rock. Conversely, black soils are unpopular for embankments. Lateritic soils respond to cement stabilization and, in some cases, lime stabilization. Andosols should also respond to lime treatment and cement treatments if proper mixing can be achieved. Black expansive residual soils respond to lime treatment by demonstrating strength gains and decreased expansiveness. Rainfall induced landslides are typical of residual soil deposits.

  10. Evaluation of residue drum storage safety risks

    International Nuclear Information System (INIS)

    A study was conducted to determine if any potential safety problems exist in the residue drum backlog at the Rocky Flats Plant. Plutonium residues stored in 55-gallon drums were packaged for short-term storage until the residues could be processed for plutonium recovery. These residues have now been determined by the Department of Energy to be waste materials, and the residues will remain in storage until plans for disposal of the material can be developed. The packaging configurations which were safe for short-term storage may not be safe for long-term storage. Interviews with Rocky Flats personnel involved with packaging the residues reveal that more than one packaging configuration was used for some of the residues. A tabulation of packaging configurations was developed based on the information obtained from the interviews. A number of potential safety problems were identified during this study, including hydrogen generation from some residues and residue packaging materials, contamination containment loss, metal residue packaging container corrosion, and pyrophoric plutonium compound formation. Risk factors were developed for evaluating the risk potential of the various residue categories, and the residues in storage at Rocky Flats were ranked by risk potential. Preliminary drum head space gas sampling studies have demonstrated the potential for formation of flammable hydrogen-oxygen mixtures in some residue drums

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

    2016-04-01

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

    Full Text Available Cryptococcus neoformans é a levedura capsulada causadora de criptococose em humanos e animais. A variedade neoformans, encontrada em diversas fontes ambientais, inclusive habitats de aves, é importante causa de mortalidade em indivíduos com AIDS em todo o Mundo. Contudo, ainda não há estudos sobre a sua ecologia na região Centro Oeste brasileira, onde há registro da ocorrência de casos humanos da micose. Para estudar fontes saprofíticas de C. neoformans, na cidade de Campo Grande, foram coletadas 20 amostras de excretas de aves em distintos ambientes. Suspensão das amostras em salina estéril foram semeadas em placas com meio ágar níger. Após 5 dias, colônias mucóides marrom-escuro foram subcultivadas para identificação através de provas morfofisiológicas, determinação da variedade e sorotipagem. C. neoformans var. neoformans sorotipo A foi isolado de 10 (50% das amostras, comprovando a ocorrência saprofítica de C. neoformans na cidade de Campo Grande, relacionada a habitat de aves em cativeiro.

    Full Text Available El artículo recoge la narración de Kawaloule, un antropólogo graduado de la Universidad Nacional de Colombia, quien expone su experiencia personal de trabajo de campo en La Guajira. A través de su relato se abordan algunos temas cruciales para el trabajo de campo antropológico, como lo son el problema del acceso al campo, el establecimiento de relaciones personales con los sujetos investigados, el papel de los antropólogos en los contextos de investigación, las formas de observar y de participar en los contextos de interacción, el registro de la información, el uso del diario de campo, las motivaciones para escoger los lugares, los temas y los problemas de investigación, el surgimiento de nuevas inquietudes junto con la problematización y conceptualización de la realidad estudiada, la confrontación de las teorías y de las ideas preestablecidas con los hechos, entre otras cosas. Apoyándose en la oralidad y con un enfoque descriptivo, el artículo propone sentar las bases empíricas sobre las cuales se pueda dar trámite a discusiones epistemológicas sobre el trabajo de campo en la antropología y sobre la identidad personal y profesional de los antropólogos.
