    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

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

    Il campo magnetico terrestre è una proprietà intrinseca del nostro pianeta e di altri oggetti del sistema solare. Il Sole stesso possiede un forte campo magnetico che si inverte quasi ciclicamente ogni 10-11 anni; tale comportamento è visibile attraverso la medesima ciclicità delle macchie solari che denotano sulla superficie l’intensa attività magnetica della nostra stella. Il campo magnetico terrestre è importantissimo per la vita sulla Terra. Esso protegge il pianeta dalle p...

El analisis teorico se efectuo por aproximacion de deriva. El paso del plasma se consigue gracias a las 'corrientes de cortocircuito' cuya existencia habfa sido supuesta por K. D. Sinelnikov. Las comentes de cortocircuito reducen sustancialmente los campos de polarizacion, pero, como demuestran los calculos, no impiden la deriva de los iones pesados hacia las paredes de la camara.

    The inter-diffusion of plasma and magnetic field is studied in pinch and hardcore discharges in a large bore, linear discharge tube (TIBER). The variation with magnetic field configuration, initial pressure, peak current, pre-heat conditions and rise time is found. The rapid ('anomalous') field diffusion found in the pinch case is due to a hydromagnetic rather than an electrostatic instability.

    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)

    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.

    The Selective Collection Program of the Campos Basin, implanted in May 1996, aims to devote adequately the recyclable waste generated at the site of PETROBRAS in the Campos Basin and the rescue environmental awareness with the practice of not wasting materials classified as recyclable. It is always to remember that education is the basis for everything and that the results of investments in environmental education be perceived slow, and takes time and perseverance. The structure of the Selective Collection Program consists of the separation of waste at source, transportation, segregation, storage and appropriate final destination. The PETROBRAS has important role in this context, reinforcing its compromise to quality of local communities life with social and environmental responsibility. (author)

    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.

    Chlorella ha ocupado la atención de los biotecnólogos al ser una importante fuente de biomasa para la producción de metabolitos de interés químico farmacéutico e industrial; sin embargo, el manejo de cultivos a gran escala sigue siendo un proceso que necesita economizarse, a partir de alternativas viables. Este trabajo presenta un estudio exploratorio en el que se evaluó la viabilidad del uso del residual de la línea de ablandamiento del grano de soya, como medio de cultivo para la microalga Chlorella vulgaris, obteniéndose excelentes valores de densidad celular máxima (Kmáx: 360 x 106 cél.mL-1. Posteriormente se evalúan los efectos de la aplicación de un campo magnético (CM de 0.03T, obteniéndose densidades celulares máximas en un menor tiempo de cultivo, lo que puede constituir un fundamento esencial para una nueva metodología de cultivo. La calidad de la biomasa de C. vulgaris se evalúa desde el punto de vista bioquímico, lo que permite determinar la concentración de proteínas, carbohidratos y lípidos en la fase exponencial, cuya acumulación se ve favorecida dependiendo del protocolo de aplicación del CM, mientras que la concentración de lípidos es máxima si el CM es aplicado en la fase estacionaria, variando desde 1.70 ±0.02 hasta 3.48 ±0.03 pg cél; lo que constituiría una ventaja para el manejo de cultivos comerciales de esta microalga que depende de su destino.

    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.

    Using the propagator's technique in the grand ensemble developed by Montroll and Ward we investigate the magnetic properties of an interacting electron gas in a strong magnetic field. The free propagator properly constructed shows that the spin paramagnetism does not have a term with strong temperature dependence, contrary to the result of Isihara.

    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.

    Using the propagator's technique in the grand ensemble developed by Montroll and Ward we investigate the magnetic properties of an interacting electron gas in a strong magnetic field. The free propagator properly constructed shows that the spin paramagnetism does not have a term with strong temperature dependence, contrary to the result of Isihara. Considering the electron density to be constant, the dHVA oscillations in the magnetic susceptibility and sound velocity, considering the effects of first exchange interactions, show only one phase in agreement with experimental result, while Ichimura and Isihara obtained two phases differing by {pi}/2. The effects of first order exchange interactions in the dHVA oscillations of the magnetic susceptibility and sound velocity give rise to an exponential factor in the amplitudes of oscillator (Dingle factor), being the Dingle temperature linearly dependent of the Fermi velocity. The calculations of the ring diagram contribution to the grand partition function, show that the approximation used by Isihara for this calculations is not good and the dHVA oscillations of the contributions from the ring diagrams for the grand partition function have a phase differing by {pi}/2 from that obtained by Isihara.

    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 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)

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.

    In petroleum industry the phenomenon of build-up of organic deposits, basically of paraffinic nature, into surface equipment, flow lines and columns has been one of the greatest problems concerning the production and transfer of crude oils, leading to significant and increasing losses in production. The approach through the application of magnetic field is a novel technique, neither explained nor exploited altogether, not one that turns out to be a simple preventive solution for the problem requiring low investment and showing expressive benefits, provided its effectiveness is confirmed. The main results of laboratory test where the effects of application of magnetic fields on the properties of two crude oil types, one mixture of paraffins and two reference solution were evaluated are presented herein, and this paper also approaches the influence of process variables (Magnetization temperature, exposure time and magnetic field density) on the efficiency of this process of treatment.

A extended study of the 1{sigma}g ground state (J.C. Lopez and A.Turbiner, Phys.

    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)

    Full Text Available RESUMO:Tendo como ponto de partida a questão sobre o futuro das escolas rurais ou do campo, o artigo aborda o contexto social, político e econômico que suporta ou não a existência das escolas, bem como uma análise sobre a situação das escolas em diferentes contextos, particularmente no Brasil, em Portugal e nos Estados Unidos. Problematizamos as respostas dadas pelo poder público, acadêmicos e organizações e movimentos sociais sobre o fechamento, a redução do número de alunos e de comunidades rurais com escola, as condições de funcionamento, a distância percorrida pelos alunos, além das implicações das escolas para a vitalidade do campo. Concluímos que o futuro das escolas está diretamente relacionado com o futuro do campo.

  14. Residual stresses

    Sahotra, I.M.

    2006-01-01

    The principal effect of unloading a material strained into the plastic range is to create a permanent set (plastic deformation), which if restricted somehow, gives rise to a system of self-balancing within the same member or reaction balanced by other members of the structure., known as residual stresses. These stresses stay there as locked-in stresses, in the body or a part of it in the absence of any external loading. Residual stresses are induced during hot-rolling and welding differential cooling, cold-forming and extruding: cold straightening and spot heating, fabrication and forced fitting of components constraining the structure to a particular geometry. The areas which cool more quickly develop residual compressive stresses, while the slower cooling areas develop residual tensile stresses, and a self-balancing or reaction balanced system of residual stresses is formed. The phenomenon of residual stresses is the most challenging in its application in surface modification techniques determining endurance mechanism against fracture and fatigue failures. This paper discusses the mechanism of residual stresses, that how the residual stresses are fanned and what their behavior is under the action of external forces. Such as in the case of a circular bar under limit torque, rectangular beam under limt moment, reclaiming of shafts welds and peening etc. (author)

  15. Residual stresses

    International Nuclear Information System (INIS)

    Macherauch, E.

    1978-01-01

    Residual stresses are stresses which exist in a material without the influence of external powers and moments. They come into existence when the volume of a material constantly changes its form as a consequence of mechanical, thermal, and/or chemical processes and is hindered by neighbouring volumes. Bodies with residual stress are in mechanical balance. These residual stresses can be manifested by means of all mechanical interventions disturbing this balance. Acoustical, optical, radiological, and magnetical methods involving material changes caused by residual stress can also serve for determining residual stress. Residual stresses have an ambivalent character. In technical practice, they are feared and liked at the same time. They cause trouble because they can be the cause for unexpected behaviour of construction elements. They are feared since they can cause failure, in the worst case with catastrophical consequences. They are appreciated, on the other hand, because, in many cases, they can contribute to improvements of the material behaviour under certain circumstances. But they are especially liked for their giving convenient and (this is most important) mostly uncontrollable explanations. For only in very few cases we have enough knowledge and possibilities for the objective evaluation of residual stresses. (orig.) [de

    A summary is presented of the many investigations that have been done on solid residues of atmospheric fluid bed combustion (AFBC). These residues are bed ash, cyclone ash and bag filter ash. Physical and chemical properties are discussed and then the various uses of residues (in fillers, bricks, gravel, and for recovery of aluminium) are summarised. Toxicological properties of fly ash and stack ash are discussed as are risks of pneumoconiosis for workers handling fly ash, and contamination of water by ashes. On the basis of present information it is concluded that risks to public health from exposure to emissions of coal fly ash from AFBC appear small or negligible as are health risk to workers in the coal fly ash processing industry. 35 refs., 5 figs., 12 tabs

    The properties of the residual nilpotence and the residual solubility of groups are studied. The main objects under investigation are the class of residually nilpotent groups such that each central extension of these groups is also residually nilpotent and the class of residually soluble groups such that each Abelian extension of these groups is residually soluble. Various examples of groups not belonging to these classes are constructed by homological methods and methods of the theory of modules over group rings. Several applications of the theory under consideration are presented and problems concerning the residual nilpotence of one-relator groups are considered.

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

    2015-06-01

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

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

    In the last decades, the irrigated agricultural areas have increased in Murcia, S. E. Spain, especially in the agrarian District Comarca del Campo de Cartagena. A consequence of this increase is the high use of fertilizers resulting to an excess of nutrients such as nitrogen. Another problem associated with the agricultural is the disposal of the increasing amount of organic agricultural residues from post-harvest practices. In this research we will study the effects of recycling crop residues as an organic fertilizer in vegetable production as a disposal management technique to reduce the amount of post-harvest residues.

    2011-09-01

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

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

    It has been proposed in the literature a new regime for high critical temperature superconductors labeled as thermally activated flux flow (TAFF). This regime presents a state in which vortex dynamic exhibit a ohmic behavior. The resistivity in this regime is proportional to the applied magnetic field for small current densities. Materials showing this behavior have high disordering and present semiconductor behavior in normal state with broad transition temperature. In this work is presented a systematic study of the magnetoresistance as a function of the applied magnetic field for polycrystalline samples with several thickness. Results of X ray diffraction, resistivity as a function of the temperature, I-V characteristic curves and magnetoresistance are showed. Finally is proposed a calibration curve of the magnetoresistance as a function of the magnetic field, that show the possibility of its use as magnetic field sensor. (author)

    An analytical model for the description of the movement of a charged particle in the interaction of an electromagnetic pulse elliptically polarized propagating along of a static and homogeneous external magnetic field in a plasma starting from the force equation is presented. The method allows to express the solution in terms of the invariant phase, obtaining differential equations for the trajectory of the accelerated particle by means of an electromagnetic pulse of arbitrary amplitude and modulated by an encircling Gaussian. The numerical solutions reported in this work can find varied applications, for example in the physics of the interaction laser-plasma, in the acceleration of particles, in hot plasma and in radiative effects.

    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.

    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.

    2015-06-01

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

    Neste trabalho e investigado o impacto de um campo magnetico externo na estrutura do diagrama de fases da Cromodinâmica Quântica (QCD). O estudo e realizado utilizando o modelo efetivo de Nambu-Jona-Lasinio para tres sabores acoplado ao loop de Polyakov (modelo de PNJL). A interacao de entanglement (modelo de EPNJL) na presenca de um campo magnetico e tambem estudada. Ambas as transicoes quiral e de desconfinamento na presenca de um campo magnetico externo podem ser analisadas usando os modelos de PNJL e EPNJL. Para o modelo de EPNJL e verificado que a coincidencia das temperaturas pseudocriticas de ambas as transicoes quiral e de deconfinamento dependem da parametrizacao da interacao de entanglement. E realizado um estudo sistematico do efeito de um campo magnetico externo nas transicoes quiral e de desconfinamento a potencial quimico barionico nulo, e.g., calculando a dependencia das temperaturas pesudocriticas com a intensidade do campo magnetico. O impacto de um campo magnetico externo no comportamento do quark estranho e analizado detalhadamente. E mostrado que a temperatura pseudocritica associada a transicao quiral do quark estranho e pouco sensivel a presenca de um campo magnetico externo. Alem disso, a sua grande massa corrente torna o quark estranho pouco sensivel ao termo de 't Hooft, contrariamente a forte influencia que tem nos quarks leves. Ambos os modelos de PNJL e EPNJL preveem o efeito de Catalise Magnetica a qualquer temperatura, mas nao reproduzem o efeito de Catalise Magnetica Inversa (CMI) em redor da temperatura pseudocritica de transicao, obtido em resultados recentes da LQCD. Mostramos que e possivel reproduzir a CMI se a intensidade da interacao entre quarks diminuir com o campo magnetico. Propomos dois mecanismos que reproduzem o efeito de CMI, que assumem o enfraquecimento da constante de acoplamento da interacao escalar com o aumento da intensidade do campo magnetico.

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

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

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

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

    2013-01-01

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

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

    2017-12-01

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

    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)

    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)

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

    Science.gov (United States)

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

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

    Full Text Available A disjunct distribution pattern between the extrazonal formations of the campos rupestres (rocky grasslands in the Espinhaço mountain range and the restingas (coastal strand vegetation in Brazil has been proposed repeatedly for several flowering-plant species. In order to validate this distribution pattern, available data from the literature and major herbaria were compiled and evaluated. Some of these species also occur in campos rupestres on mountain ranges in Goiás state, campos de altitude (high altitude grasslands of the Serra do Mar, and on geologically homologous rocky formations of the Guyana shield. Species that were also recorded for distinct zonal formations like cerrado, caatinga and forests were excluded from the pattern. The campo rupestre-restinga disjunction proved valid for 9 of 56 investigated species (16%. Explanations put forth by different authors for this unusual disjunction pattern are compared in the light of geological and climatological evidence.Um padrão de distribuição disjunta entre as formações extrazonais conhecidas por campos rupestres na cadeia do Espinhaço e as restingas do litoral brasileiro vem sendo repetidamente proposto para algumas espécies de fanerógamas.

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

    The 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

    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) [es

    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

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

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

    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).

    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)

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

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

    CERN Document Server

    Wright, Steve

    2016-01-01

    This book offers an account of the classical theory of quadratic residues and non-residues with the goal of using that theory as a lens through which to view the development of some of the fundamental methods employed in modern elementary, algebraic, and analytic number theory. The first three chapters present some basic facts and the history of quadratic residues and non-residues and discuss various proofs of the Law of Quadratic Reciprosity in depth, with an emphasis on the six proofs that Gauss published. The remaining seven chapters explore some interesting applications of the Law of Quadratic Reciprocity, prove some results concerning the distribution and arithmetic structure of quadratic residues and non-residues, provide a detailed proof of Dirichlet’s Class-Number Formula, and discuss the question of whether quadratic residues are randomly distributed. The text is a valuable resource for graduate and advanced undergraduate students as well as for mathematicians interested in number theory.

    1998-05-01

    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).

    2015-09-01

    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.

Viene, così, messo in discussione il mito della gratuità e del disinteresse del lavoro intellettuale insieme a quello dell’esperienza estetica come identificazione immediata e contemplazione dell’opera. Le istanze di legittimazione interne al campo, infatti, determinano i modi della produzione, ma anche quelli dell’appropriazione.

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

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

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

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

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

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

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

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

    1983-01-01

    Acid digestion treatment of nuclear waste is similar to incineration processes and results in the bulk of the waste being reduced in volume and weight to some residual solids termed residue. The residue is composed of various dispersible solid materials and typically contains the resultant radioactivity from the waste. This report describes the immobilization of the residue in portland cement, borosilicate glass, and some other waste forms. Diagrams showing the cement and glass virtification parameters are included in the report as well as process steps and candidate waste product forms. Cement immobilization is simplest and probably least expensive; glass vitrification exhibits the best overall volume reduction ratio

  16. 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.

    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.

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

    Full Text Available Há tempos sendo tema de reflexões e discussões entre pensadores, teóricos e artistas, a relação interartes se mantém e se renova nas manifestações artísticas contemporâneas. Hoje, o elo entre as artes e as discussões sobre o tema se estendem para outros campos, indo além da literatura e da pintura, e incluindo a fotografia, o cinema e, ainda, novas mídias, como a publicidade e o videoclipe. Este artigo apresenta uma reflexão sobre o elo entre diferentes formas de arte, o engendramento de uma obra de arte em outra, demonstrando mecanismos do exercício interartes, a partir da tela de Vincent Van Gogh, Campo de trigo com corvos. Propõe-se, então, uma análise sobre a maneira como o tema da pintura, as cores azul e amarelo, bem como os corvos, aparecem em outras manifestações artísticas, neste caso a poesia (À luz dos vegetais, de Contador Borges, o cinema (Sonhos, de Akira Kurosawa, a música e o videoclipe (Corvos sobre o campo, da banda Tantra.

    The present work was carried out to assess the 210 Pb content in 'black-powder' found in pigging operations on gas pipelines in Brazil, in particular, on the Campos Basin gas pipeline. Additionally, the chemical composition of such deposits was determined and an eventual correlation with 210 Pb concentration evaluated. Typical 'black-powder' generated in the natural gas pipeline from Campos Basin oilfield contains mainly iron oxide (∼81%) and residual organic matter (∼9%). The 210 Pb content ranges from 4.9 to 0.04 kBq kg -1 and seems to be inversely correlated with the distance to the platforms. On the other hand, 226 Ra concentration is higher on the pipeline branch between the platform and the onshore installations. 228 Ra was only observed in few samples, in particular, in the samples with the highest 226 Ra content

    Residual stress by repair welds is computed using the thermal elastic-plastic analysis with phase-transformation effect. Coupling phenomena of temperature, microstructure, and stress-strain fields are simulated in the finite-element analysis. Weld bond of a plate butt-welded joint is gouged and then deposited by weld metal in repair process. Heat source is synchronously moved with the deposition of the finite-element as the weld deposition. Microstructure is considered by using CCT diagram and the transformation behavior in the repair weld is also simulated. The effects of initial stress, heat input, and weld length on residual stress distribution are studied from the organic results of numerical analysis. Initial residual stress before repair weld has no influence on the residual stress after repair treatment near weld metal, because the initial stress near weld metal releases due to high temperature of repair weld and then stress by repair weld regenerates. Heat input has an effect for residual stress distribution, for not its magnitude but distribution zone. Weld length should be considered reducing the magnitude of residual stress in the edge of weld bead; short bead induces high tensile residual stress. (author)

  18. RESIDUAL RISK ASSESSMENT: ETHYLENE OXIDE ...

    Science.gov (United States)

    This document describes the residual risk assessment for the Ethylene Oxide Commercial Sterilization source category. For stationary sources, section 112 (f) of the Clean Air Act requires EPA to assess risks to human health and the environment following implementation of technology-based control standards. If these technology-based control standards do not provide an ample margin of safety, then EPA is required to promulgate addtional standards. This document describes the methodology and results of the residual risk assessment performed for the Ethylene Oxide Commercial Sterilization source category. The results of this analyiss will assist EPA in determining whether a residual risk rule for this source category is appropriate.

    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. Desde la decada de los 80 se han realizado diversos estudios y acciones en ese campo geotermico para recargar al yacimiento y para disponer del fluido residual, sin ocasionar danos al ambiente ni a los cuerpos hidricos del subsuelo, que van desde la infiltracion hasta la inyeccion en frio y en caliente. Este articulo presenta los diferentes estudios realizados con ese objetivo en el campo, incluyendo el analisis de litofacies, de nucleos de formacion, de registros de presion, temperatura y spinner, las pruebas en pozos y analisis de tasas de aceptacion, asi como los efectuados en el acuifero superficial. Todos ellos han sido de utilidad para atender los requerimientos de las autoridades ambientales. Finalmente, y en virtud de que las tasas de aceptacion de los pozos

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

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

    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.

Nesse texto, Malinowski expõe suas justificativas para o tipo de aproximação que realizou para estudar uma população melanésia da década de 1910, aproximação desde então consagrada na antropologia mediante a idéia de "trabalho de campo". Pretendo, de minha parte, demonstrar que as mesmas justificativas, colocadas dentro dos quadros propiciados por objetos bem diversos, podem fundamentar uma outra aproximação metodológica. Nesse sentido, continuar "fiel" a Malinowski significa relê-lo (e mesmo subvertê-lo de forma a explorar certas virtualidades de seu texto, acionadas com base em situações de pesquisa com que os antropólogos se deparam atualmente, permitindo adequar à disciplina metodologias que não se definem estritamente como "trabalho de campo".

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

    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.

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

    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.

  16. Nitrogen availability of biogas residues

    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.

  5. Evaluation of residue-residue contact prediction in CASP10

    Monastyrskyy, Bohdan

    2013-08-31

    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.

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

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

    Directory of Open Access Journals (Sweden)

    Luca Cossettini

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

    Full Text Available Un campo aleatorio espacio-temporal es un modelo probabilista utilizado para representar fenómenos que, además de variar espacialmente, cambian con el tiempo. Este tipo de modelo es de gran interés práctico en ingeniería porque permite representar fenómenos transitorios y generar configuraciones o imágenes de la distribución de un atributo o variable condicionado a observaciones temporales. En este artículo se propone una formulación alternativa de una variante del método EnKF (Ensemble Kalman Filter (Evensen, 2007 basada en conceptos comunes en geoestadística y explica con detalle su desarrollo numérico. La utilidad del método se ilustra resolviendo un problema de flujo de agua transitorio en un medio poroso aleatorio completamente saturado.

    Full Text Available This paper presents a diagnosis of sanitation in the Ururaí neighborhood, located in Campos, Brazil. The study was based on both quantitative and qualitative data gathering methods using the following research instruments: photographic record, semi-structured interviews with residents, and physicochemical and microbiological analysis of water quality of the residences and of the Ururaí River. The photographic records did not find one consistency of the local sanitation system. Interviews conducted with one area of the neighborhood show that 63% of residents are not satisfied with the sanitation service, while questionnaires applied in the second area present a higher percentage - 83%. During the investigation, we verified the presence of coliform bacteria in water samples collected in the Ururaí River as well as at residences. Based on the results, we found precariousness of services involving sanitation in the area. Therefore, this work proposes future educational activities in the region.

    Cristóbal Soto Solano

    Full Text Available ABSTRACT The objective of this research was to identify and characterize the main technical factors that affect the deployment of the mechanized harvesting of sugarcane in Campos dos Goytacazes, Rio de Janeiro, Brazil. In general, it can be stated there were restrictive factors related to machinery, administrative management, and technical planning. We identified significant technical restrictions in the planting system, particularly in relation to the size and shape of the plots, length of the rows, row spacing, and inadequate varieties. For efficient use of mechanized harvesting, a technical planning is necessary with changes in the cropping system, adopting wider and more uniform plots regarding to its format, with rows over 500 m length and row spacing of 1.50 m and upright, productive, and deep-rooted varieties.

  6. Residual stresses around Vickers indents

    Pajares, A.; Guiberteau, F.; Steinbrech, R.W.

    1995-01-01

    The residual stresses generated by Vickers indentation in brittle materials and their changes due to annealing and surface removal were studied in 4 mol% yttria partially stabilized zirconia (4Y-PSZ). Three experimental methods to gain information about the residual stress field were applied: (i) crack profile measurements based on serial sectioning, (ii) controlled crack propagation in post indentation bending tests and (iii) double indentation tests with smaller secondary indents located around a larger primary impression. Three zones of different residual stress behavior are deduced from the experiments. Beneath the impression a crack free spherical zone of high hydrostatic stresses exists. This core zone is followed by a transition regime where indentation cracks develop but still experience hydrostatic stresses. Finally, in an outward third zone, the crack contour is entirely governed by the tensile residual stress intensity (elastically deformed region). Annealing and surface removal reduce this crack driving stress intensity. The specific changes of the residual stresses due to the post indentation treatments are described and discussed in detail for the three zones

  7. Minimization of zirconium chlorinator residues

    International Nuclear Information System (INIS)

    Green, G.K.; Harbuck, D.D.

    1995-01-01

    Zirconium chlorinator residues contain an array of rare earths, scandium, unreacted coke, and radioactive thorium and radium. Because of the radioactivity, the residues must be disposed in special waste containment facilities. As these sites become more congested, and with stricter environmental regulations, disposal of large volumes of wastes may become more difficult. To reduce the mass of disposed material, the US Bureau of Mines (USBM) developed technology to recover rare earths, thorium and radium, and unreacted coke from these residues. This technology employs an HCl leach to solubilize over 99% of the scandium and thorium, and over 90% of the rare earths. The leach liquor is processed through several solvent extraction stages to selectively recover scandium, thorium, and rare earths. The leach residue is further leached with an organic acid to solubilize radium, thus allowing unreacted coke to be recycled to the chlorinator. The thorium and radium waste products, which comprise only 2.1% of the original residue mass, can then be sent to the radioactive waste facility

    A new process for recovery of plutonium and americium from pyrochemical waste has been demonstrated. It is based on chloride solution anion exchange at low acidity, which eliminates corrosive HCl fumes. Developmental experiments of the process flowsheet concentrated on molten salt extraction (MSE) residues and gave >95% plutonium and >90% americium recovery. The recovered plutonium contained 6 = from high chloride-low acid solution. Americium and other metals are washed from the ion exchange column with 1N HNO 3 -4.8M NaCl. The plutonium is recovered, after elution, via hydroxide precipitation, while the americium is recovered via NaHCO 3 precipitation. All filtrates from the process are discardable as low-level contaminated waste. Production-scale experiments are now in progress for MSE residues. Flow sheets for actinide recovery from electrorefining and direct oxide reduction residues are presented and discussed

    One of the major causes of deactivation of Ni/Mo and Co/Mo sulfide catalysts for hydroprocessing of heavy petroleum and bitumen fractions is coke deposition. The composition and amount of coke deposited on residue hydroprocessing catalysts depends on the composition of the liquid phase of the reactor. In the Athabasca bitumen, the high molecular weight components encourage coke deposition at temperatures of 430 to 440 degrees C and at pressures of 10 to 20 MPa hydrogen pressure. A study was conducted to determine which components in the heavy residual oil fraction were responsible for coking of catalysts. Seven samples of Athabasca vacuum residue were prepared by supercritical fluid extraction with pentane before being placed in the reactor. Carbon content and hydrodesulfurization activity was measured. It was concluded that the deposition of coke depended on the presence of asphaltenes and not on other compositional variables such as content of nitrogen, aromatic carbon or vanadium.

    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.

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

  9. 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.

Ele aborda o protagonismo do MPA – Movimento dos Pequenos Agricultores, na interface entre agricultura familiar e educação do campo. Trabalhamos com o plano camponês, uma das principais armas do MPA. Ele representa um contraponto à incapacidade estatal na criação de leis que apoiem os pequenos agricultores. Desenvolvemos uma pesquisa bibliográfica e documental, utilizando as seguintes fontes de investigação: legislações, portarias, decretos e referenciais sobre educação do campo no Brasil. Utilizamos ainda os dados do censo agropecuário de 2006, ressaltando o valor da agricultura familiar na mesa do brasileiro. Nesse contexto, verificamos que o processo de ensino e aprendizagem deve dialogar com a realidade concreta dos sujeitos, individuais e coletivos, articulados com a luta pela terra. Concluímos que a produção coletiva do saber em parceria com educandos/as, educadores/as, comunidades e os movimentos sociais de luta pela terra, pode dialogar com histórias, memórias, identidades, desejos, valores e reconhecimento, fortalecendo o debate em torno da educação do campo, na sua estreita relação com movimentos sociais, escolas do campo e universidades públicas.

    1993-12-31

    Historically, the majority of sawmill waste has been burned or buried for the sole purpose of disposal. In most jurisdictions, environmental legislation will prohibit, or render uneconomic, these practices. Many reports have been prepared to describe the forest industry`s residue and its environmental effect; although these help those looking for industry-wide or regional solutions, such as electricity generation, they have limited value for the mill manager, who has the on-hands responsibility for generation and disposal of the waste. If the mill manager can evaluate waste streams and break them down into their usable components, he can find niche market solutions for portions of the plant residue and redirect waste to poor/no-return, rather than disposal-cost, end uses. In the modern mill, residue is collected at the individual machine centre by waste conveyors that combine and mix sawdust, shavings, bark, etc. and send the result to the hog-fuel pile. The mill waste system should be analyzed to determine the measures that can improve the quality of residues and determine the volumes of any particular category before the mixing, mentioned above, occurs. After this analysis, the mill may find a niche market for a portion of its woodwaste.

  17. Leptogenesis and residual CP symmetry

    2016-01-01

    We discuss flavour dependent leptogenesis in the framework of lepton flavour models based on discrete flavour and CP symmetries applied to the type-I seesaw model. Working in the flavour basis, we analyse the case of two general residual CP symmetries in the neutrino sector, which corresponds to all possible semi-direct models based on a preserved Z 2 in the neutrino sector, together with a CP symmetry, which constrains the PMNS matrix up to a single free parameter which may be fixed by the reactor angle. We systematically study and classify this case for all possible residual CP symmetries, and show that the R-matrix is tightly constrained up to a single free parameter, with only certain forms being consistent with successful leptogenesis, leading to possible connections between leptogenesis and PMNS parameters. The formalism is completely general in the sense that the two residual CP symmetries could result from any high energy discrete flavour theory which respects any CP symmetry. As a simple example, we apply the formalism to a high energy S 4 flavour symmetry with a generalized CP symmetry, broken to two residual CP symmetries in the neutrino sector, recovering familiar results for PMNS predictions, together with new results for flavour dependent leptogenesis.

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

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

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

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

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.

Como en el resto de Hispanoamérica, descubrir estos relatos en su calidad de textos, esto es, más allá de su función documental, implica el reconocimiento de sus complejas estrategias discursivas y, en lo que respecta a su relación con la tradición autobiográfica europea, de sus frecuentes “desvíos de la letra”. Resulta particularmente de interés observar la posición incómoda de sus cultores, quienes deben justificar el empleo de la primera persona y la singularidad de su experiencia, en un medio en que prima la valoración del pudor. Frente a este juicio adverso, desarrollan tácticas para conseguir el perdón y beneplácito de sus lectores, en un campo literario en el que lentamente se va abriendo paso este tipo de producciones, de carácter moderno y subjetivo.Even though there are texts of an autobiographical nature in Chile that date from Colonial times, they are not considered part of the national literary field until well into the XX Century; quite the opposite, they are excluded from overviews and bibliographical registries by critics and historians. Like in the rest of Spanish America, discovering autobiographical accounts as texts in their own right (that is, beyond their documental function, implies the recognition of their complex discursive strategies and becoming aware of the ‘deviation from the letter’ these texts represent when it comes to their relationship with the European autobiographical tradition.

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

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

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

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

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

    Regina Horta Duarte

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

  15. Energetic aspects and opportunities for reusing water on offshore platforms in Campos Basin, Brazil

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

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

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

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

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

    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.

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

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

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

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

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

    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 terms Residual Life Management, Life Cycle Management and Long-Term Management are synonymous with a concept which aims to establish efficient maintenance for the profitable and safe operation of a power plant for as long as possible. A Residual Life Management programme comprises a number of stages, of which Maintenance Evaluation focuses on how power plant maintenance practices allow the mitigation and control of component ageing. with this objective in mind, a methodology has been developed for the analysis of potential degradative phenomena acting on critical components in terms of normal power plant maintenance practices. This methodology applied to maintenance evaluation enables the setting out of a maintenance programme based on the Life Management concept, and the programme's subsequent up-dating to allow for new techniques and methods. Initial applications have shown that although, in general terms, power plant maintenance is efficient, the way in which Residual Life Management is approached requires changes in maintenance practices. These changes range from modifications to existing inspection and surveillance methods or the establishment of new ones, to the monitoring of trends or the performance of additional studies, the purpose of which is to provide an accurate evaluation of the condition of the installations and the possibility of life extension.

    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 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) [Spanish] El objetivo principal de esta investigacion es la caracterizacion de los residuos solidos.

    Concrete grinding residue is the waste product resulting from the grinding, cutting, and resurfacing of concrete pavement. Potential beneficial applications for concrete grinding residue include use as a soil amendment and as a construction material, including as an additive to Portland cement concrete. Concrete grinding residue exhibits a high pH, and though not hazardous, it is sufficiently elevated that precautions need to be taken around aquatic ecosystems. Best management practices and state regulations focus on reducing the impact on such aquatic environment. Heavy metals are present in concrete grinding residue, but concentrations are of the same magnitude as typically recycled concrete residuals. The chemical composition of concrete grinding residue makes it a useful product for some soil amendment purposes at appropriate land application rates. The presence of unreacted concrete in concrete grinding residue was examined for potential use as partial replacement of cement in new concrete. Testing of Florida concrete grinding residue revealed no dramatic reactivity or improvement in mortar strength.

    Full Text Available As condições climáticas atuais indicam avanço da vegetação de floresta sobre os campos na região dos Campos de Cima da Serra no Rio Grande do Sul. Essa mudança na vegetação altera o conteúdo de matéria orgânica e a umidade do solo. Este estudo objetivou avaliar os óxidos de ferro pedogênicos em um Latossolo sob campo e floresta nativa e relacionar os mesmos com os teores de carbono orgânico e a área superficial específica do solo. Os teores de carbono orgânico são maiores no solo sob floresta e, possivelmente, influenciaram processos dissolutivos de óxidos de ferro cristalinos e a neoformação de tipos metaestáveis de baixa cristalinidade. O incremento de C orgânico no solo sob floresta elevou expressivamente a área superficial específica do solo, mascarando o efeito geralmente positivo dos óxidos de Fe sobre essa característica física.

    2009-01-01

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

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

Objetiva especificamente analisar o discurso do associativismo arquivístico sobre a institucionalização das esferas acadêmico-universitária do saber arquivístico e sua reserva de mercado profissional. A abordagem metodológica foi utilizar os editoriais da revista Arquivo & Administração, entre 1971 e 1978, selecionando enunciações sobre o processo de institucionalização do campo arquivístico. As análises apontam para uma década de incessantes esforços para eliminar, do campo profissional, o livre exercício da ocupação, para fortalecer o âmbito da formação. Associado à seleção dos enunciados significativos, depreendeu-se a rede de pessoas interessadas nos arquivos, em condições históricas de restrição política, que construiu articulações frente ao Estado, diante de pontos de vista contrários, se tornando um movimento associativo realizador em suas demandas.

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

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

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

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

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

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

    The oil extraction and production industry generates several types of solid and liquid wastes. Scales, sludge and water are typical residues that can be found in such facilities and that can be contaminated with Naturally Occurring Radioactive Material (N.O.R.M.). As a result of oil processing, the natural radionuclides can be concentrated in such residues, forming the so called Technologically Enhanced Naturally Occurring Radioactive Material, or T.E.N.O.R.M.. Most of the radionuclides that appear in oil and gas streams belong to the 238 U and 232 Th natural series, besides 40 K. The present work was developed to determine the radionuclide content of scales and sludge generated during oil extraction and production operations. Emphasis was given to the quantification of 226 Ra, 228 Ra and 40 K since these radionuclides,are responsible for most of the external exposure in such facilities. Samples were taken from the P.E.T.R.O.B.R.A.S. unity in the State of Sergipe, in Northeastern Brazil. They were collected directly from the inner surface of water pipes and storage tanks, or from barrels stored in the waste storage area of the E and P unit. The activity concentrations for 226 Ra, 228 Ra and 40 K were determined by using an HP Ge gamma spectrometric system. The results showed concentrations ranging from 42.7 to 2,110.0 kBq/kg for 226 Ra, 40.5 to 1,550.0 kBq/kg for 228 Ra, and 20.6 to 186.6 kBq/kg for 40 K. The results highlight the importance of determining the activity concentration of those radionuclides in oil residues before deciding whether they should be stored or discarded to the environment.

It is shown that the seabed liquefaction under standing waves, although qualitatively similar, exhibits features different from that caused by progressive waves....... The experimental results show that the buildup of pore-water pressure and the resulting liquefaction first starts at the nodal section and spreads towards the antinodal section. The number of waves to cause liquefaction at the nodal section appears to be equal to that experienced in progressive waves for the same...

    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.

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

  12. Residual Stresses In 3013 Containers

    The DOE Complex is packaging plutonium-bearing materials for storage and eventual disposition or disposal. The materials are handled according to the DOE-STD-3013 which outlines general requirements for stabilization, packaging and long-term storage. The storage vessels for the plutonium-bearing materials are termed 3013 containers. Stress corrosion cracking has been identified as a potential container degradation mode and this work determined that the residual stresses in the containers are sufficient to support such cracking. Sections of the 3013 outer, inner, and convenience containers, in both the as-fabricated condition and the closure welded condition, were evaluated per ASTM standard G-36. The standard requires exposure to a boiling magnesium chloride solution, which is an aggressive testing solution. Tests in a less aggressive 40% calcium chloride solution were also conducted. These tests were used to reveal the relative stress corrosion cracking susceptibility of the as fabricated 3013 containers. Significant cracking was observed in all containers in areas near welds and transitions in the container diameter. Stress corrosion cracks developed in both the lid and the body of gas tungsten arc welded and laser closure welded containers. The development of stress corrosion cracks in the as-fabricated and in the closure welded container samples demonstrates that the residual stresses in the 3013 containers are sufficient to support stress corrosion cracking if the environmental conditions inside the containers do not preclude the cracking process.

    Full Text Available Clinically insignificant residual fragments (CIRFs are described as asymptomatic, noninfectious and nonobstructive stone fragments (≤4 mm remaining in the urinary system after the last session of any intervention (ESWL, URS or PCNL for urinary stones. Their insignificance is questionable since CIRFs could eventually become significant, as their presence may result in recurrent stone growth and they may cause pain and infection due to urinary obstruction. They may become the source of persistent infections and a significant portion of the patients will have a stone-related event, requiring auxilliary interventions. CT seems to be the ultimate choice of assessment. Although there is no concensus about the timing, recent data suggests that it may be performed one month after the procedure. However, imaging can be done in the immediate postoperative period, if there are no tubes blurring the assessment. There is some evidence indicating that selective medical therapy may have an impact on decreasing stone formation rates. Retrograde intrarenal surgery, with its minimally invasive nature, seems to be the best way to deal with residual fragments.

    Developmental dyscalculia - a congenital learning disability in understanding numerical concepts - is typically associated with parietal lobe abnormality. However, people with dyscalculia often retain some residual numerical abilities, reported in studies that otherwise focused on abnormalities in the dyscalculic brain. Here we took a different perspective by focusing on brain regions that support residual number processing in dyscalculia. All participants accurately performed semantic and categorical colour-decision tasks with numerical and non-numerical stimuli, with adults with dyscalculia performing slower than controls in the number semantic tasks only. Structural imaging showed less grey-matter volume in the right parietal cortex in people with dyscalculia relative to controls. Functional MRI showed that accurate number semantic judgements were maintained by parietal and inferior frontal activations that were common to adults with dyscalculia and controls, with higher activation for participants with dyscalculia than controls in the right superior frontal cortex and the left inferior frontal sulcus. Enhanced activation in these frontal areas was driven by people with dyscalculia who made faster rather than slower numerical decisions; however, activation could not be accounted for by response times per se, because it was greater for fast relative to slow dyscalculics but not greater for fast controls relative to slow dyscalculics. In conclusion, our results reveal two frontal brain regions that support efficient number processing in dyscalculia.

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

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

    1995-01-01

    The Swedish market for upgraded residue fuels, i.e. briquettes, pellets and wood powder, has developed considerably during the nineties. The additional costs for the upgrading processes are regained and create a surplus in other parts of the system, e.g. in the form of higher combustion efficiencies, lower investment costs for burning equipment, lower operation costs and a diminished environmental impact. All these factors put together have resulted in a rapid growth of this part of the energy sector. In 1994 the production was 1.9 TWh, an increase of 37 % compared to the previous year. In the forthcoming heating season 1995/96 the production may reach 4 TWh. 57 refs, 11 figs, 6 tabs

    Full Text Available The ruminants are capable of converting low-quality food, when they are complementes with high-energy source. Through the use of regional agricultural residues is possible to conduct more economical production systems, since energetic foods have high cost in animal production. There is very abundant availability of residues in agroforestry activities worldwide, so that if a small fraction of them were used with appropriate technical criteria they could largely meet the needs of existing herds in the world and thus meet the demands of consumption of protein of animal origin. The Southwest Region of São Paulo State has large area occupied by reforestation and wide availability of non-timber forest residues, which may represent more concentrated energetic food for ruminant production. This experiment aimed to evaluate the acceptability of ground pine (20, 30 and 40%, replacing part of the energetic food (corn, present in the composition of the concentrate and was performed at the Experimental Station of Itapetininga - Forest Institute / SMA, in the dry season of 2011.

It is estimated that more than 1.8 million tons of SR have been landfilled in mono cells. This paper describes investigations conducted at two Danish landfills. SR were excavated...... from the landfills and size fractionated in order to recover potential resources such as metal and energy and to reduce the amounts of SR left for re-landfilling. Based on the results it is estimated that 60-70% of the SR excavated could be recovered in terms of materials or energy. Only a fraction...... with particle size less than 5 mm needs to be re-landfilled at least until suitable techniques are available for recovery of materials with small particle sizes....

    Rodis, Harry G.; Suszczynski, Edison F.

    1972-01-01

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

    CERN Document Server

    Kunz, Ernst; Dickenstein, Alicia

    2008-01-01

    This book, which grew out of lectures by E. Kunz for students with a background in algebra and algebraic geometry, develops local and global duality theory in the special case of (possibly singular) algebraic varieties over algebraically closed base fields. It describes duality and residue theorems in terms of K�hler differential forms and their residues. The properties of residues are introduced via local cohomology. Special emphasis is given to the relation between residues to classical results of algebraic geometry and their generalizations. The contribution by A. Dickenstein gives applications of residues and duality to polynomial solutions of constant coefficient partial differential equations and to problems in interpolation and ideal membership. D. A. Cox explains toric residues and relates them to the earlier text. The book is intended as an introduction to more advanced treatments and further applications of the subject, to which numerous bibliographical hints are given.

  11. Using cotton plant residue to produce briquettes

    Energy Technology Data Exchange (ETDEWEB)

    Coates, W. [University of Arizona, Tucson, AZ (United States). Bioresources Research Facility

    2000-07-01

    In Arizona, cotton (Gossypium) plant residue left in the field following harvest must be buried to prevent it from serving as an overwintering site for insects such as the pink bollworm. Most tillage operations employed to incorporate the residue into the soil are energy intensive and often degrade soil structure. Trials showed that cotton plant residue could be incorporated with pecan shells to produce commercially acceptable briquettes. Pecan shell briquettes containing cotton residue rather than waste paper were slightly less durable, when made using equivalent weight mixtures and moisture contents. Proximate and ultimate analyses showed the only difference among briquette samples to be a higher ash content in those made using cotton plant residue. Briquettes made with paper demonstrated longer flame out time, and lower ash percentage, compared to those made with cotton plant residue. (author)

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

    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.

    Full Text Available En este artículo se abordan algunos aspectos de la controversia sobre la iniciativa «Código de barras del ADN», y se hace hincapié en sus potenciales aplicaciones en Entomología. Esta iniciativa propone emplear información dentro de una misma región génica (gen mitocondrial de la Citocromo c Oxidasa I = COI, en todas las especies vivientes y con condiciones de secuenciación universalmente aceptadas y estandarizadas. En la actualidad, no pretende sustituir la taxonomía alfa y la filogenia sino agilizar las tareas de identificación, especialmente en el campo de la Biomedicina (identificación de patógenos, parásitos y vectores, el control de plagas (intercepción de especies invasoras, cualquiera sea su estado de desarrollo ontogenético y los estudios sobre conservación de la biodiversidad. Para arribar a una correcta delimitación de las especies biológicas es preciso contar con las secuencias de COI de numerosos individuos a lo largo de todo su rango geográfico y además, secuencias de genes nucleares e información morfológica y biológica detallada. Las «Unidades Evolutivas Significativas», identificadas sobre la base del «código de barras», podrían corresponder tanto a morfoespecies como a especies crípticas y a subespecies o linajes con diferentes preferencias de huéspedes. La integración del «código de barras del ADN», el trabajo de campo, las colecciones de museos y la investigación científica resultan imprescindibles para que esta herramienta redunde en avances significativos en el campo de la Sistemática Entomológica.

  15. O imaginário rural do leitor urbano: o sonho mítico da casa no campo

    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.

  16. Mapeamento de campos hidromórficos na serra Catarinense por meio de modelagem hidrológica

    Directory of Open Access Journals (Sweden)

    Jorgeane Schaefer-Santos

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

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

  20. O desafio da análise de redes de saúde no campo da saúde coletiva

    Directory of Open Access Journals (Sweden)

    Carlos Eduardo Menezes Amaral

    Full Text Available Resumo A organização do cuidado no Sistema Único de Saúde tem conferido destaque às redes de atenção, tanto no campo discursivo como na sua tradução em estratégias concretas. Contudo, são escassos os aportes analíticos e avaliativos abarcando as redes enquanto objeto. Neste artigo, apresentamos alguns subsídios sob forma de um construto multidimensional que dialoga com as contribuições de autores do campo da saúde coletiva e de outros campos disciplinares que se debruçaram sobre o tema. Nossa proposta apresenta cinco dimensões, sistematizadas depois de um exercício conduzido pelo método analítico reflexivo, tomando como material 23 artigos concernentes a distintos aspectos relevantes à análise de redes de saúde. Esse exercício, operacionalizando um processo sucessivo de redução semântica, resultou em um modelo composto pelas seguintes dimensões: Unidades mínimas, compreendendo a caracterização dos pontos fixos a partir dos quais ocorrem as conexões da rede; Conectividade, representando as modalidades e efeitos das relações estabelecidas entre as unidades mínimas; Integração, concernente aos efeitos do conjunto das unidades mínimas e suas relações, identificados como coerência, continuidade e complementaridade de ações na rede; Normatividade, indicando a construção e adesão a diretrizes clínicas e linhas de cuidado singulares, assim como o estabelecimento de critérios de encaminhamento, entrada e saída de cada ponto da rede; e Subjetividade, incluindo protagonismos, sentidos, valores e vínculos afetivos circulantes na rede. Essas dimensões, operando de forma recursiva, podem subsidiar a construção de modelos analítico-conceituais de redes como aporte à superação desse desafio no campo da saúde coletiva.

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

    1981-01-01

    Carbaryl residues in two local maize varieties were determined using a colorimetric method. No significant differences were observed for residues of the two varieties which ranged between 12.0 to 13.75 mg/kg in the crude oil, and averaged 1.04 and 0.67 mg/kg in the flour and cake respectively. In whole maize plants, carbaryl residues declined to approximately 2 mg/kg 35 days after treatment. Cooking in aqueous, oil or aqueous-oil media led to 63-83% loss of carbaryl residues, after 30 minutes. (author)

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

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

    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.

  1. Process for measuring residual stresses

    International Nuclear Information System (INIS)

    Elfinger, F.X.; Peiter, A.; Theiner, W.A.; Stuecker, E.

    1982-01-01

    No single process can at present solve all problems. The complete destructive processes only have a limited field of application, as the component cannot be reused. However, they are essential for the basic determination of stress distributions in the field of research and development. Destructive and non-destructive processes are mainly used if investigations have to be carried out on original components. With increasing component size, the part of destructive tests becomes smaller. The main applications are: quality assurance, testing of manufactured parts and characteristics of components. Among the non-destructive test procedures, X-raying has been developed most. It gives residual stresses on the surface and on surface layers near the edges. Further development is desirable - in assessment - in measuring techniques. Ultrasonic and magnetic crack detection processes are at present mainly used in research and development, and also in quality assurance.

En meme temps, la tension dans le conducteur auxiliaire diminue; elle est aussi fortement amortie par rapport a celle qui correspond a la marche a vide, ce qui indique une absorption efficace de l'energie du circuit par le plasma. L'energie absorbee par le plasma au cours de la premiere periode du courant, c'est-a-dire pendant environ 1 {mu}s, represente environ 20 J; on constate d'ailleurs que la conductibilite du plasma est anormalement faible.

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

    Full Text Available El presente artículo contiene una serie de reflexiones elaboradas al poner en diálogo experiencias de campo en el marco de investigaciones individuales; una, con indígenas adscriptos como Huarpes, en el noreste de la provincia de Mendoza; la otra, con indígenas adscriptos como Qom. Éstas reflexiones intentan contribuir a desnaturalizar y visibilizar la complejidad de los contextos de interacción, considerando que abarcan distintas dimensiones y aspectos —tales como posición de los interlocutores en la estructura social, expectativas individuales, experiencias y relaciones previas de los sujetos, y recursos materiales y simbólicos en intermediación—, enfatizando así el carácter situacional y dinámico de esas relaciones de interlocución.A la luz de los actuales debates de la crítica cultural y en un intento por contribuir a los estudios de la Etnografía Colaborativa, el objetivo de este artículo es exponer y describir comparativamente lo que entendemos como performances de campo, situando como objeto de análisis la experiencia etnográfica en sí misma. Entendiendo el trabajo etnográfico como proceso y texto, identificamos tres grandes nudos críticos, reunidos en tres escenas etnográficas, que analizamos como una red multisituada de mediaciones e interrelaciones.

    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 The purpose of this paper is to analyze the workers’ health care in the Unified Health System (SUS, in the municipality of Campos dos Goytacazes, from the creation of the Network for Integral Worker Health Care - RENAST in 2002 to 2012. Therefore, it aims at elucidating the role of Reference Centres for Occupational Health (CEREST, the number of accidents at work and occupational diseases in those ten years, as well as the organization of the Network for Integral Worker Health Care (RENAST, according to the decree of the Ministry of Health. The objective is to verify the efficiency of municipal policies regarding workers’ health through documentary sources, quantitative data, and oral sources. The survey verified the absence of data on strategic actions aimed at the workers’ health, various health care activities, and the political-electoral use of PAST (Workers’ Health Care Program and CEREST. Considering the evolution of the concepts related to health care of those who work, in some sectors, Campos dos Goytacazes has gone through a period that precedes the “industrial medicine” stage - Occupational Medicine. This reality shows bad labor relations, as the municipality is the national champion in work analogous to slave labor. In most cases, the city has to deal with regulatory standards and, in very few moments, puts into practice principles of Workers’ Health.

  8. From obc seismic to porosity volume: A pre-stack analysis of a turbidite reservoir, deepwater Campos Basin, Brazil

    Science.gov (United States)

    Martins, Luiz M. R.

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

    Full Text Available RESUMO: A presente pesquisa teve por objetivo analisar, a partir do brincar, elementos que podem contribuir para a observação da vivência das crianças do campo. Participou da pesquisa uma turma com oito crianças da Educação Infantil do Campo de uma escola no município de Vitória da Conquista, Bahia. Como procedimentos de investigação, foram empregados observação direta, com registros fotográficos, e rodas de conversa. O material produzido pelas crianças nas rodas de conversa (a partir das fotos permitiu identificar significados e alguns sentidos do contexto das crianças, tais como a integração com elementos da natureza e com animais, assim como uma vivência com elementos específicos do seu cotidiano doméstico, como a lenha, a espingarda e os meios de transporte da região. As discussões apontam que a escola não oferece o contato com elementos da natureza que fazem parte do meio rural em que as crianças vivem.

    Cláudia Chaves Fonseca

    2017-04-01

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

  12. La intuición clínica de Sigmund Freud en el campo de la psicosis

    Directory of Open Access Journals (Sweden)

    Joceline Zanchettin

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

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

    2011-01-01

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