    Precision Agriculture (PA) is a technique that can reduce the inputs utilization in agriculture production, including the nitrogen fertilizer consume. Great importance is given to this fertilizer, due to its contribution on energy input in agriculture. Methodologies based on the calculation of energy flow of agriculture systems are capable to identify management practices that use energy more efficiently. So, this study's objective is to evaluate the variable-rate nitrogen fertilization on wheat, using energy assessment. This study was carried on in two wheat fields, in which the fertilization was done adopting strips alternated by conventional method (single nitrogen dose) and by nitrogen variable-rate technology. Thus, the input and output energy in the system, energy balance, energy return on investment (EROI) and incorporated energy were determined for each geo-referenced point within the fields. Results showed that less energy was demanded when using variable-rate technology, due to the nitrogen saving, providing greater energy balance, EROI and lower incorporated energy on the areas managed using PA. The energy assessment showed to be an important tool to evaluate systems that use PA, because it is capable of monitoring crops energy potential. (author)

    Most Brazilian constructions have low performance in terms of energy, since they received little attention (or none) concerning the energy efficiency. One of the main aspects observed is the intense use of electric energy for climatization and lighting in order to provide comfortable conditions for the dwellers. In 2009, new perspectives to change this situation emerged, due to an initiative by the Federal Government, that established the necessary regulations for energy efficiency labelling in buildings, and broadened the Brazilian Labelling Program (PBE), which, up until then, encompassed only machinery and equipment. The purpose of this article is to analyze the compliance with the new regulations for energy efficiency of constructions in the hotel sector, where small businesses are predominant, aiming at highlighting the barriers and opportunities connected to the possibilities of labeling. Hotels have been targeted for large investments, since they have become the pillars of Brazil's project to welcome tourists during the 2014 World Cup and the 2016 Olympic Games. Taking into consideration the need to develop specific methodologies for lodging possibilities, in addition to the scarce information on the use of energy in small businesses, this article is part of a series of researches carried out within the framework of the Sebrae/RJ - Procel Agreement. The outcome is a global analysis, from a business point of view, on the use of labels of energy efficiency in hotel buildings, organized upon two perspectives: the external environment (opportunities and threats) and the internal environment (strong and weak points).

    1978-07-01

    This work consists in the development of an analytical method using activation by thermal neutrons for the determination of some minor elements and traces present in cassiterite (tin ore). This method was then applied to determine these elements in samples of cassiterite from different regions of Brazil. An analysis was made of the mineralogy characteristic of cassiterite as well as of the minerals most commonly associated with it. Four main types of interference were found to occur in the analysis by activation of trace elements in samples of cassiterite. The method involves the analysis without chemical separation for the determination of some elements and the analysis with chemical separation for the determination of other elements. The steps involved in both types of analysis are described. In the analysis with chemical separation the matrix element (tin) is separated by distillation in an H{sub 2}SO{sub 4}-HBr medium, after fusion of the ore with Na{sub 2}O{sub 2}. Arsine and antimony are determined in the distilled, whereas some lanthanide elements and uranium are determined in the distillation residue by separating them as a group by precipitation with lanthanum fluoride. A discussion on the precision, accuracy and sensibility of the method is also included. (author)

    Full Text Available 0 presente trabalho pretende analisar o modo como a Análise do discurso derivada de Michel Pêcheux se relacionava com uma das regiões do conhecimento que estão na sua base — o marxismo ou a ciência da história. 0 nosso ponto de partida é expor o modo como o próprio Pêcheux via essa relação da AD com a referida ciência, no período de elaboração e maturação da disciplina (anos 69 a 75. Para isso, primeiramente, mostramos o sentido amplo que Pêcheux, na linha do grupo althusseriano, atribuía expressão "ciência da história". Mostramos, em seguida, que o projeto pecheutiano de desenvolver a teoria e a análise do discurso se entroncava no projeto althusseriano de desenvolver urna teoria das ideologias. Consideramos a reconstrução do modo como Pêcheux entendia a relação entre a AD e a ciência da história importante, porque a expressão "ciência da história" tem um sentido especial que é freqüentemente ignorado e, por isso, tem conduzido à interpretação apressada que define aAD como uma "disciplina de entremeio", situada entre a ciência da história, a Lingüística e a Psicanálise, interpretação essa que Pêcheux recusava explicitamente.

    The differential and GPT (Generalized Perturbation Theory) formalisms of the Perturbation Theory were applied in this work to a simplified U-tubes steam generator model to perform sensitivity analysis. The adjoint and importance equations, with the corresponding expressions for the sensitivity coefficients, were derived for this steam generator model. The system was numerically was numerically solved in a Fortran program, called GEVADJ, in order to calculate the sensitivity coefficients. A transient loss of forced primary coolant in the nuclear power plant Angra-1 was used as example case. The average and final values of functionals: secondary pressure and enthalpy were studied in relation to changes in the secondary feedwater flow, enthalpy and total volume in secondary circuit. Absolute variations in the above functionals were calculated using the perturbative methods, considering the variations in the feedwater flow and total secondary volume. Comparison with the same variations obtained via direct model showed in general good agreement, demonstrating the potentiality of perturbative methods for sensitivity analysis of nuclear systems.

    The eggs are among the twenty foods consumed by the population of the five major regions of Brazil. Among the types of eggs, there are differences in nutritional value, which can vary according to the food of the bird. This study evaluating the elements Cl, K, Mg, Mn and Na considered essential micronutrients in food, because they are fundamental in several metabolic processes necessary for the maintenance and training of the human body. We analyzed three types of eggs: egg whites, of the quail, and the colonial in cooked and raw form, using the Instrumental Neutron Activation Analysis method (INAA). The egg samples were lyophilized and pulverized before analysis. To validate the methodology, reference materials NIST RM 8415 Whole Egg Powder and NIST SRM 1567 Wheat Flour were analyzed. The samples, reference materials and standards of the elements were irradiated for 20 seconds under a thermal neutron flux of 6,6x10{sup 12} cm -2 s -1 in the nuclear research reactor IEA-R1 of IPEN-CNEN / SP. The results were consistent with the values of the Brazilian Table of Food Composition (TACO)

    The use of Natural Gas is nowadays increasing in Brazilian scene and this fact shows the necessity of effective planning tasks in that sector. In the case of Natural Gas Vehicular (NGV) distribution one can face problems of actor's (distributor, retailers, customers and non-users) point of view conflicts and fuel stations expand in most Brazilian urban areas in an uncontrolled way, despising counties regulation on land use. This paper reports a study using a model based in Game Theory concepts to determine some key-variables as the number of fuel stations which must deliver NGV in a given study area. Although some information could not be available the results of simulation shows the usefulness of using such an approach to give solutions to distribution questions in NGV sector. The model was applied to the case of a district in Fortaleza city which is the study area of a project entitled Projeto GASLOG presently on process under the sponsoring of Brazilian Government, PETROBRAS and Brazilian GasEnergy Research Network.

    Metals are components of the biosphere, occurring naturally in soil and plants, but as a result of human actions, their levels have been greatly increased, depending on the region. Copper (Cu) and zinc (Zn) are essential for the growth and development of plants, however if in excess become toxic. The aim of this study was to evaluate the potential of plants to absorb Cu and Zn and what effects they cause in seedlings cultivated in vitro. The results of this study may contribute primarily in agricultural and environmental research. The plant investigated was the Aechmea blanchetiana species of the Bromeliaceae family. It is a terrestrial or epiphytic species used as an ornamental plant. The cultivation of seedlings for this study and their exposure to different concentrations of Cu and Zn were performed at the Institute of Botany (IBt) of Sao Paulo. After seed germination, the seedlings were transferred for growth in a culture media containing different concentrations of Cu or Zn. After this period of in vitro cultivation, the seedlings were analyzed for morphometry, anatomy and by neutron activation analysis. Quality control of the results from neutron activation analysis was carried out by the analysis of certified reference materials. The data obtained showed good precision and accuracy for several elements determined. The highest concentrations of Cu used in the exposure were those that caused major structural changes in morphometric and anatomical parameters, however for the Zn no significant differences were verified for most parameters. The A. blanchetiana proved to be a bioaccumulator species of Zn, absorbing high levels of this element in the aerial parts and roots. (author)

    The volume of stranded natural gas global reserves is substantial and represents more than a third of the world's proven natural gas reserves. In Brazil, recent discoveries operated by PETROBRAS, with participation of other companies, show trend of stranded gas reserves incorporation, associated gas or not. This dissertation's main objective is to make a technical and economic analysis of the implementation of small-scale GTL technology for the exploitation of stranded associated natural gas offshore in Brazil. Thus, the dissertation held, initially, a survey of the processes of gasification and the manufacturers with technologies and projects based on these processes, for specific offshore applications. In a second stage, the conditions of the offshore environment were examined. After the confrontation of the technologies available and the operation conditions, a technological alternative has been chosen to be used in an illustrative economic analysis. The results show that GTL offshore option becomes viable at a minimum price of about US $ 40.00 / barrel. Although this value is greater than the robustness price adopted by PETROBRAS, there are prospects for the reduction of GTL technology costs. (author)

    Objectives: This study examines the structural and thermal modifications induced in dental enamel under dye assisted diode laser irradiation. The aim of this study is to verify if this laser-assisted treatment is capable to modify the enamel surface by causing fusion of the enamel surface layer. At the same time, the pulpal temperature rise must be kept low enough in order not to cause pulpar necrosis. To achieve this target, it is necessary to determine suitable laser parameters. As is known, fusion of the enamel surface followed by re-solidification produce a more acid resistant layer. This surface treatment is being researched as a new method for caries prevention. Method and Materials: A series of fourteen identically prepared enamel samples of human teeth were irradiated with a high power diode laser operating at 960 nm and using fiber delivery. Prior to irradiation, a fine layer of cromophorous ink was applied to the enamel surface. In the first part of the experiment the best parameter for pulse duration was determined. In the second part of the experimental phase the same energy density was used but with different repetition rates. During irradiation we monitored the temperature rise in the pulpal cavity. The morphology of the treated samples was analysed under SEM. Results: The morphology of the treated samples showed a homogeneously re-solidified enamel layer. The results of the temperature analysis showed a decrease of the pulpal temperature rise with decreasing repetition rate. Conclusion: With the diode laser it is possible to cause morphological alterations of the enamel surface, which is known to increase the enamel resistance against acid attack, and still maintain the temperature rise in the pulpar chamber below damage threshold.

    The goal of this paper is to present the work in the thesis developed by Silva Jr. (2005) who discusses the application of the methodologies of Life Cycle Cost Analysis (LCCA) as a tool to propose energy efficiency standards, additional to the voluntary labels already existing in the one-door Brazilian refrigerators. Another objective is to study the role of these instruments (energy efficiency labels and standards and environmental labels) as means to supply technical subsidies for the establishment of maximum level of electric energy consumption and environmental quality impact for electrical equipment in Brazil. The LCCA methodology allows to evaluate the impacts of the energy efficiency increasing in electrical equipment, resulting in important saving (energy, financial, carbon dioxide emissions avoided etc.) for the country and its citizens. The results reached in this studies offer important data to subsidize deep discussions with manufacturers and the government to stipulate minimum energy efficiency standards for the Brazilian refrigerators. Thus, with increase of 28,1% on the energy efficiency of the one-door Brazilian refrigerators in 2008 to reach a values of savings that can be in order of 54,63 TWh (with respective reduction of demand power of 208 MW), of US$ 6,23 Billions of Dollar (R$ 17,2 Billions of Reais) of reduction in the account of electric energy for the population and of approximately 22 billions of tons of CO{sub 2} not emitted on the environment after 30 years of the implantation of standard. These values, that can not be despised by government, manufacturers and consumers. One other interest of this work is to start the discussion, the possibility of the creation of environmental labelling (e.g., Green Seal - USA, Eco-label - EU etc.) that is an additional program/methodology, which, it may be utilized as support for development of technologies and for the increase of energy and environmental efficiency of the electric equipment. These labels are strategically important for Brazil to amplify the environmental programs to their products because they can facilitate the insertion of these products in the international market, at the same time, that the country gets in the increase of the quality (environmental etc.) and promotes the sustainable development around the world.

    The increased demand for natural gas leads to global integration of markets, leading to decisions that cover the various technologies of transportation, noting the specific locations. The transport of natural gas considered more traditional (Liquefied Natural Gas and Pipeline) often unviable economically areas of operation due to cost. In this case, there are alternative technologies to reduce those costs. The article is to compare the technologies of transport, using the methodology of the Net Present Value (VPL) to identify one that has more positive VPL, which is the most profitable. Thus, in search of validate the results of SUBERO et al. (2004) for gas transport by Pipelines, Liquefied Natural Gas and Compressed Natural Gas. In addition, they are compared these results with the method of VPL and with the economic analysis presented in using the payback period of CHANG (2001) and SANTAREM et al. (2007). It was found that the results obtained in Brazil were identical to those obtained by CHANG (2001) and SUBERO et al. (2007), saving only some differences in magnitude due to the specific characteristics of the Brazilian economy. In other words, for the Brazilian case, the technology of Compressed Natural Gas (CNG) was the most economically viable with the method of VPL, followed by technology, Pipeline and Liquefied Natural Gas (LNG), regardless of the interest rates of 10% and 6.5% and periods of 20 and 30 years. The contribution of this work is to show that despite of the method, payback or VPL, the various alternatives for transporting natural gas to Brazil have the same ranking and economic viability.

    Multi-elementary and considered non destructive, the neutron activation analysis is a technique that allows simultaneous and instrumental determination of several elements, becoming especially useful when it is fundamental the knowledge of the total chemical composition, as in the certification of reference materials, application in geochemistry, analyses of aerosols, determination of origin of materials, forensic analyzes and of environmental pollution. However, the dependence of reactors, or other neutrons sources, the generation of radioactive material and the time waiting needed for some determinations are the main barriers pointed int he application of that technique. The present work aimed at establishing the best conditions for the detection of elements of short half-life Br, K, La, Mn, Na and Sm in samples of wood of Pinus, because the reactor used is located distant of the laboratory where the measures of the induced radioactivity are made, to determine trace elements that possess half-lives smaller than two days. For such, suitable equations, using the Surface of Response technique in the SAS software, to minimize the uncertainties of detection of the photopeak function of the elementary concentration and as a decay time.(author) 6 refs., 3 figs., 11 tabs.

    The objective of this paper was to evaluate the quality of the brain structure segmentation in magnetic resonance images (MRI) through a comparison between automatic and semiautomatic volumetric segmentation techniques. T1-weighed volumetric acquired stacks of MRI head images from Centro de Diagnostico por Imagens at the Hospital Sao Lucas da PUCRS were used in this study. In the semi-automatic segmentation technique were applied procedures like pre-processing and region-growing using Image J software. The automatic method of volume segmentation was carried through by Statistical Parametric Mapping (SPM), a statistical analysis tool written for software MATLAB. The automatic method of volumetric segmentation had better performance in time. However the quality of image that the half-automatic segmentation presents a better detailing, but it required longer image processing time. The best method to be used, whether automatic or semi-automatic, depends on the region of interest. (author)

    This work intended to study the methodologies used for EIA - Study of Environmental Impact - and propose the adaptation of a simplified matrix for the assessment of environmental impacts regarding small hydropower plants. A case study of Ninho da Aguia SHP, located in the city of Delfim Moreira, MG, was used for elaborating the matrix. The methodology used the analysis of all the negative impacts and they were given combined weight based on a pre-established impact scale. The weights that were given to each impact were distributed according to the combination of features presented in the referred EIA. The results attained show that the environmental damage is reduced by 45% when the mitigating measures suggested by the EIA and by the analysis carried out by this study are applied. Besides, this preliminary proposal will make it possible for environmental licensing process to be accelerated. Today, this process is considered as an inhibiting investment because of it takes too much time. Also, the proposal may be used as initial guidelines regarding the environmental cost of the implementation of enterprises. The proposed matrix shows itself as efficient because it is easy to be used and it is a useful tool for the analysis of projects that will be implemented. (author)

    Nickel-titanium alloys may coexist in more than one crystalline structure. There is a high temperature phase, austenite, and a low temperature phase, martensite. The metallurgical basis for the superelasticity and the shape memory effect relies in the ability of these alloys to transform easily from one phase to another. There are three essential factors for the orthodontist to understand nickel-titanium alloys behaviour: stress; deflection; and temperature. These three factors are related to each other by the stress-deflection, stress-temperature and deflection-temperature diagrams. This work was undertaken with the objective to analyse commercial nickel-titanium alloys for orthodontics application, using the dynamical mechanical analyser - DMA. Four NiTi 0,017 X 0,025'' archwires were studied. The archwires were Copper NiTi 35 deg C (Ormco), Neo Sentalloy F200 (GAC), Nitinol Superelastic (Unitek) and NiTi (GAC). The different mechanodynamical properties such as elasticity and damping moduli were evaluated. Each commercial material was evaluated with and without a 1 N static force, aiming to evaluate phase transition temperature variation with stress. The austenitic to martensitic phase ratio, for the experiments without static force, was in the range of 1.59 to 1.85. For the 1 N static force tests the austenitic to martensitic phase ratio, ranged from 1.28 to 1.57 due to the higher martensite elasticity modulus. With elastic modulus variation with temperature behaviour, the orthodontist has the knowledge of the force variation applied in the tooth in relation to the oral cavity temperature change, for nickel-titanium alloys that undergo phase transformation. The damping capacity of the studied alloys depends on the materials state: martensitic phase; austenitic phase or during phase transformation. The martensitic phase shows higher dumping capacity. During phase transformation, an internal friction peak may be observed for the CuNiTi 35 deg C and Neo Sentalloy F200 alloys. The austenitic phase shows a low damping capacity. According to the evaluation of the damping capacity against temperature, it was possible to better understand the phase transformation behaviour of these alloys. The differential scanning calorimetry was used in order to evaluate the phase transformation process, giving the initial and ending temperatures of the austenitic transformation and the initial and ending temperatures of the martensitic transformation of the studied alloys.

    The Araripe Basin, located in the Borborema Province, northeastern Brazil, developed through a sequence of distinct events related to the opening of the South Atlantic. Its geological history is recorded in the preserved stratigraphy, which ranges in age from Paleozoic to Middle Cretaceous. The most conspicuous feature associated with the Araripe Basin is the Araripe Plateau, a large mesa capped by Cenomanian- Albian non-marine sandstones (Exu Formation). At the plateau base, gray to black shales ('Batateiras layers') represent deposition in a large lake system covering part of northeastern Brazil during Early Aptian. Previous researchers have used the preserved geological section in the basin to infer the landscape evolution of the Araripe Plateau, and they have suggested that its uplift and exhumation were caused by widespread epeirogenic movements associated with post-break-up events in the Borborema Province. Independent constraints on the timing and magnitude of uplift in the Araripe Plateau area can now be introduced by this preliminary study using apatite fission track analysis. A series of samples along a N-S transect of the Araripe Basin and its neighboring basement provide clear evidence of heating in the past. Results from all samples also show evidence of Late Cenozoic cooling commencing sometime in the last 40 Ma. Maximum paleotemperature associated with this event are very similar (70 deg - 90 deg C) between samples, consistent with little differential movement across the sampled region. Fission track results from the Aptian sandstone sample (Rio da Batateira Formation) indicate an earlier event (pre-40 Ma). However, interpretation of data suggests that any paleo-heating between sediment deposition (112 Ma) and 40 Ma must be associated with paleotemperature less than {approx}100 deg C, pointing to minor paleo burial during the Late Cretaceous in this area. The timing of these various events are broadly consistent with the timing of events

    One of the most important steps, in order to improve the quality of foodstuffs, in the last forty years is represented by fortified foods. The fortification foods means complementary addition of nutrients to content of foodstuffs. The macro-nutrients (carbohydrates, proteins and lipids) are relativity steady when submitted to irradiation. The micro-nutrients, speciality the vitamins, can be sensible to any method. This work has analysed fortified foods with Fe, Ca, Mg, Zn, vitamin A, riboflavine, vitamin C and folic acid , as well as, the perspective of adjusting the food irradiation process with fortification foods.

    The South American Platform in southeastern Brazil records a long history of tectonic magmatic and uplift events, which resulted from the opening of the South Atlantic Ocean, Cretaceous reactivation and epirogeneic processes. Specific manifestations include the basic magmatism of the Serra Geral Formation of the Parana Basin and alkaline magmatism of Pocos de Caldas - Cabo Frio Lineament, as well as the uplift of the Serra da Mantiqueira and Serra do Mar mountain ranges. Thermo tectonic and geochronological studies using the K-Ar method and apatite fission track analysis in samples of the Pocos de Caldas alkaline massif show an initial evolution beginning 89 Ma related to a tectonic uplift, interpreted as related to the intrusion's doming. This was followed by an important episode of rapid cooling related to the formation of the massif. At the same time, the mountains that surround the massif record heating events in response to the alkaline intrusion, between 70 and 50 Ma. Periods of slow uplift, probably related to the South American Erosion Cycle (between 50 and 30 Ma) and Velhas Erosion Cycle (from 25 Ma), indicate a strong manifestation of denudation in this area.

    It is believed that the physical mechanism responsible for the transference of energy from the solar wind to the Earth magnetosphere is the reconnection between the interplanetary magnetic field and the terrestrial magnetic field (Tsurutani and Gonzalez, 1997). The necessary criterion for a intense geomagnetic storms to occur, Dst < -100nT, is the existence of a dawn-dusk interplanetary electric field larger than 5 mV/m, for a period larger than 3 hours. Cosmic rays have been studied as a natural phenomenon that can tell much about both Earth's environment in space and distant astrophysical processes (Jokipii, 2000). A solar disturbance propagating away from the Sun affects the pre-existing population of galactic cosmic rays in a number of ways. The most famous one is known as the 'Forbush decrease', which is a suppression of ground cosmic-ray counts observed during geomagnetic disturbances. The objective of this work is to study the response of the Southern Space Observatory ground Muon Telescope observations, installed in Sao Martinho da Serra, RS, Brazil, to 3 super intense geomagnetic storms, combining observation provided by L1 satellites and ground detectors.

    Introduction: This study tends to test the capacity of the computed tomography in assist in the diagnosis and the approach of the acute abdomen. Material and method: This is a longitudinal and prospective study, in which were analyzed the patients with the diagnosis of acute abdomen. There were obtained 105 cases of acute abdomen and after the application of the exclusions criteria were included 28 patients in the study. Results: Computed tomography changed the diagnostic hypothesis of the physicians in 50% of the cases (p < 0.05), and the confidence index in 85.71% of the cases (p 0.014). Computed tomography also altered the management in 46.43% of the cases (p > 0.05), where 78.57% of the patients had surgical indication before computed tomography and 67.86% after computed tomography (p = 0.0546). The index of accurate diagnosis of computed tomography, when compared to the anatomopathologic examination and the final diagnosis, was observed in 82.14% of the cases (p = 0.013). When the analysis was done dividing the patients in surgical and nonsurgical group, were obtained an accuracy of 89.28% (p 0.0001). The difference of 7.2 days of hospitalization (p = 0.003) was obtained compared with the mean of the acute abdomen without use the computed tomography. Conclusion: The computed tomography is correlative with the anatomopathology and has great accuracy in the surgical indication, associated with the capacity of increase the confident index of the physicians, reduces the hospitalization time, reduces the number of surgeries and is cost-effective.

    The aim of this study was to estimate the cost of electric and diesel power for the application of 1 mm of irrigation in an area of 1 hectare. The Tariff Group considered was 'B' for low voltage and subgroup 'B2 Rural'. The fares used were obtained from CEMIG, being of R$ 0.22019. The diesel value adopted was the month of November 2010 in the southern region of Minas Gerais, comprising $ 1.97 L{sup -1}. For purposes of calculation, the total income of the height manometric were taken, respectively, 60%, 65%, 70%, 75% and 10, 25, 75, 100, 125, 150, 175 and 200 mca. To calculate the total cost with the application of the depth of 1mm was considered that the cost of energy accounts for 65% and 75% for electric and diesel, respectively. The results show a increase in energy costs by increasing the total head. The use of systems more efficient pump reduces the cost of electric power in the order of 6.7% to 20% and diesel from 3.6% to 16.2% for the proposed situations. In all cases the electric power is more appropriate with regard to cost. The relationship between electricity and diesel is 51.62% and 15.98% for better and worse, respectively. (author)

    Although the Brazilian Legislation does not clearly specify the requirements and the need to elaborate and apply the Environmental Risk Analysis, the Term of Reference to submit studies to Environmental Entities for E and P offshore activities has required the presentation of an {sup E}nvironment Risk Analysis{sup .} Nevertheless, the interactions or possible effects of these accidents as well as possible chronic discharges are not focused. The Environment Risk Analysis programs used world wide for offshore petroleum activities are very sophisticated and need intense research, specially by universities to be adequate and applicable in Brazil. The studies briefly described in this work, when developed may give the characteristics of Brazilian offshore, important information on the potential of the environment impact of the E and P activities, reducing significantly today's subjectivity on evaluation of impacts and environmental risks.

    The wood density constitutes the main wood quality parameter by its relationship with anatomical, physical and chemical properties and wood utilization. The modern and accurate methods - like X-ray densitometry - are applied to determine the density spatial distribution in wood sections and pith-bark direction. On the other hand, emphasis to wood utilization from fast growing plantations, like Gmelina arborea in Costa Rica, has been done. The objectives of this study were to determinate the influence of 2 climatic conditions of Costa Rica on radial wood density variation of gmelina trees form fast growing plantations using the X-ray densitometry method. Wood samples were cut at DBH of gmelina trees and transversal thin laths were selected at north-south direction and conditioned at 12% moisture content equilibrium and X-rayed. The radiographic films were revealed and scanned a 256 gray scale with 1000 dpi resolution and the intra tree-ring density were determined by CRAD and CERD software. The results demonstrated that the climatic and forest management affects the wood density variability and the distinctness of tree-ring boundaries of gmelina trees, as well as, the applicability of X-ray densitometry in wood quality analysis.

    The most common synthetic drilling fluids are made of polymerized olefins, paraffin and esters, which have absence of aromatics hydrocarbons and biodegradability as advantages. These fluids have good performance during the drilling operations (high thermal stability) and have low toxicity. Nevertheless, their big disadvantage is the high cost, which limits their use. One of the biggest challenges in working with synthetic fluids is the control of water/oil emulsion stability, being the surfactant the main agent responsible for keeping this stability between both phases of the fluid. The water/oil and oil/water emulsion is defined by the chemical nature of the surfactant. The emulsions can be changed from oil/water to water/oil and vice versa by many mechanisms, such as temperature variation, addition of another surfactant and alteration of the disperse phase volumetric percentage. The aim of this work was the optimization of synthetic drilling fluids formulations by using commercial surfactants. The optimized formulations showed similar rheological properties. After aging at high temperature (300 deg F), some tendency to migration of oil phase in both fluids was observed. This result was associated to the fluid's viscosity. However, the formulations showed high electrical stability, indicating formation of stable emulsions. The HTHP filtration volumes were small. (author)

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

    Irradiation has been recognized as an efficient method for the reduction of deteriorating and pathogenic microorganisms in foods. Propolis is a resinous product made by bees from material processed by the bee's own metabolism and resins from plants. The aim of this work was the application of gamma irradiation technique for the preservation of propolis, because of its efficiency in the reduction of the microbial load. The changes on the total flavonoids content, phenolic compounds and other characteristics required for the qualification and characterization of Brazilian propolis were also analysed. Propolis samples from Juiz de Fora region, Minas Gerais, were irradiated in a {sup 60}Co source, with doses from 0 to 10kGy for the microbiological analyses and 5.0, 7.0 and 10.0kGy for the physico-chemical analyses. The physico-chemical that have been made were: determination of total flavonoids content, semi-quantitative determination of phenolic compounds (artepelin-C, kempferol, chrysin, galangin and quercetin), dry matter analysis, humidity, ash content, mechanical mass and waxes. The ionizing radiation has shown to be efficient in the reduction of the microbial load. Total coliforms determination showed a great reduction with the dose of 3kGy and concerning mesophile aerobic bacteria a systematic reduction was observed, achieving values <10 UFC/g for the dose of 10kGy; similar results was obtained for molds and yeasts. Salmonella assays were negative for all samples. There was no significant alteration on total flavonoids contents nor on the composition of phenolic compounds as a consequence of radiation application at the assayed conditions. The complementary analyses of dry matter and humidity contents, ashes, mechanical mass and waxes did not shown changes after irradiation even with the maximum dose of 10kGy, remaining the results within the standards required by the Brazilian legislation.

    In order to verify the commissioning of the planning of intensity-modulated radiation therapy system (IMRT), the TG-119 of the American Association of Physicists in Medicine (AAPM) was applied. Using pre defined targets and normal structures, plans were realized, absolute and relative dose were measured with an ionizing chamber and films, and the results were compared with planned values. The maximum deviation of the measurements with the ionization chamber was 3,6%, but, in the total eleven measurements, only two were bigger than the tolerance limit of 3%, recommended by TG-119. The number of points which passed criteria gamma 3% to 3 mm ranged between 96.36% and 99.92%, all measurements were within the recommended 95%. The confidence limits found for both film and for chamber were lower than those achieved in the TG-119. Our results showed a good concordance with TG-119, what means that the system is adequate for clinical applications. (author)

    The results obtained in the application of the k{sub 0}-standardization method at LAN-IPEN for biological matrices analysis, by using the k{sub 0}-IAEA software, provided by the International Atomic Energy Agency (IAEA), are presented. The flux parameters f and a of the IEA-R1 reactor were determined for the pneumatic irradiation facility and for one selected irradiation position, 24B/shelf2, for short and long irradiations, respectively. In order to obtain these parameters, the bare triple-monitor method with {sup 197}Au-{sup 96}Zr-{sup 94}Zr was used. In order to evaluate the accuracy and precision of the methodology, the biological reference materials Peach Leaves (NIST SRM 1547), Mixed Polish Herbs (INCT-MPH-2) e Tomato Leaves (NIST SRM 1573a) were analyzed. The statistical criteria Relative Errors (bias, %), Coefficient of Variation (CV) and U-score were applied to the obtained results (mean of six replicates). The relative errors (bias, %) in relation to certified values, were, for most elements, in the range of 0 e 30. The Coefficients of Variation were below 20%, showing a good reproducibility of the results. The U-score test showed that all results, except Na in Peach Leaves and in Tomato Leaves, were within 95% confidence interval. These results point out to a promising use of the k{sub 0}-INAA method at LAN-IPEN for biological sample analysis. (author)

    This work analyses the methodology adopted by ANEEL in electricity distribution companies' tariff revision. The theoretical approach assumes that the institutional endowment and existing regulatory framework restricts the regulators choice of tariff revision mechanism design. Regulators choice of methodology can contribute to the creation of a good reputation, reducing uncertainties and promoting efficiency. We evaluate how the chosen methods satisfy the aspect of internal coherence among them and with the commitments found in the basic legal framework of the industry. We conclude that the adoption of a Reference Firm as a benchmark presents some coherency and transparency, but the methodology has consistency problems and is not suitable to the maturity level and administrative capacity of the regulatory system.

    This paper provides a comparison between the reactivity calculated by the approximation based on the multiplication factor (K{sub eff}) and a new approach for the reactivity calculation to be used in the kinetics point equation for subcritical systems. To obtain the necessary kinetic parameters as well and the reference Power value calculation and validation, a subcritical system was simulated with the Monte Carlo code Serpent. This study is important for determining nuclear Power in such systems. The results shown consistent values with the validation method and new in-depth studies to calculate the reactivity should be performed to such systems, making the issue a very current theme.

    1999-02-01

    This work presents some thicknesses estimates in overlapped sedimentary sections. The adopted procedure consists of the accomplishment of kriging followed by weighed corrections that provide mathematical consistency to the operation of thicknesses addition. These weighed corrections are based on the proportions between: the thicknesses of the estimated layers and the total thickness of the analyzed section; the standard deviation of the estimation error and the addition of these standard deviations; the variance of the estimation error and the addition of these variances. The proposed method is characterized by its simplicity and operational flexibility, being distinguished by: the number of intervals to be analyzed is theoretically limitless; stationary thicknesses are not required; choice of distinct neighborhoods for each analyzed interval is allowed; it has freedom for the use of distinct models in each investigated interval, making it possible to choose different functions, amplitudes and anisotropies. The technique was applied in an oil field situated in the northeast of Brazil, helping in localising the preferential depositional areas for turbiditic reservoirs and allowing inferences with respect to structural aspects of studied area.

    This work aimed to analyze the electric energy storage system generated from a photovoltaic system with lead-acid batteries. The increasing claim for energy in the world in addition to the need of using renewable energy sources in order to preserve the environment makes necessary the development of efficient techniques of power supply and control. Two photovoltaic systems were used in this work, a conventional one with stationary solar panel and another with automatic solar position system. The comparative analysis has allowed assessing the advantages of both systems. The following characteristics were obtained during the development of this work: charge, discharge, battery capacity, operating time rate, auto-discharge reaction (through fluctuation state), among other important information that allows an extended life to the stationary battery studied. The obtained results indicate that the battery connected to the mobile system provides 36% of additional energy compared to the fixed system. When the battery was unable to provide energy to the load, the battery connected to the mobile system consumed about 33% less energy than that one connected to the fixed system (author)

    The objective of this work was to evaluate the technique of magnetic resonance tomography for cashew nut analysis, compared to the traditional method of clone selection. Samples of cashew nut from 40 clones harvested in 2002 were analyzed using both methods. Using traditional method most of clones showed high and medium values of the industrial indicators nut and seed mass and industrial yield and low values of seed breakage. By magnetic resonance tomography majority of clones showed cashew nuts with empty spaces between the nut and the endocarp, which can protect the seed during decortication. The results for the two methods were complementary and the tomography, besides being a promising option for the quality evaluation of cashew nut, can give support to other researches related to cashew nut study.

    This paper analyses the institutional model adopted for the reform of the oil industry in Brazil, beginning with the approval of Law n. 9.478 by the Brazilian Parliament in 1997. The reform of the Brazilian oil industry took place in the context of the reforms of the world's national economies throughout the 1980's and 1990's. From this worldwide process of reform stemmed a huge increase in the international capital flow directed to long-run investment opportunities in the economic infrastructure sectors. The aim of this paper is to analyse both the regulatory model for the oil and gas upstream activities in Brazil and the bidding model adopted at Brazil's National Petroleum Agency's auctions for the acquisition of exploration areas. This paper is dedicated, in its entirety, to Prof. Carmen Alveal (in memoriam), whose knowledge, support, encouragement and friendship were, for me, the most important of all, professionally and morally.

    The Belo Monte hydropower plant's low generation cost is among the arguments used by Centrais Eletricas do Norte do Brazil (ELETRONORTE), a Brazilian state electric utility, to make possible its construction. This paper shows that the generation cost presented by ELETROBRAS is very low in relation to the world pattern of cost and probably unrealistic. It also shows that the generation cost cannot be used separately to determine the Belo Monte dam's economic feasibility. There is the need to include other costs, such as: socio environmental degradation and control, financial compensation for using the hydraulic resources, transmission and thermal backup stations, beyond, evidently, generation cost for assuring the credibility of the Belo Monte hydropower plant's economic analysis.

    The well test is an instrument frequently used to evaluate the production capacity of wells and it usually has specific requirements in the flow measurement, that are not necessary in the flow measurement system for custody transfer applications. Starting with the requirement to measure the injected product in the well when it is in the recuperation phase and it also includes compliance to specific standards for allocation measurement, because these hydrocarbon products are not treated as well as that ones in the production streams. Other important issue associated to the well test is the employment of new technologies, that helps to reduce the uncertainty of measurement as digital communication between the field devices and the flow computer through an open protocol as the Foundation Field bus. Another indication of technology evolution in the flow measurement focusing a lower uncertainty is the new version of API MPMS 11.1:2004, that requires calculation with double precision floating point, as well the correction factors with 5 decimal digits.

    The behavior of the ethanol industry in the coming years should be buoyed by several factors, among which gain prominence: feedstock, conversion technologies and products. This article aims, from the analysis of technological road maps, is dealing with Brazil in the face of the global market, is primarily addressing the international context, to assess which technologies tend to predominate, with emphasis on the ethanol industry, addressing convergent and complementary the technology road maps, especially regarding the barriers and challenges, costs and logistics, and other broader issues that govern the production of sustainable feedstock, conversion technologies and biofuels industry, with emphasis on ethanol. Conventional biofuels today are generally not competitive with fossil fuels at market prices, except for the cane ethanol already has a good performance in economic terms. Moreover, strategies for first generation ethanol differ from those for the second generation, which is at an earlier stage of technology development and still subject to comparatively high production costs. The non-economic fundamental barrier to the development of biofuels, particularly ethanol, is the uncertainty as to its sustainability. The debate sometimes on competition with food production and the potential destruction of valuable ecosystems put biofuels in the center of the discussion about sustainability. The challenges facing the ethanol industry range from the need to implement on a large scale to reduce costs along the production chain, through the need for second-generation technologies to reach the level of market, with the behavior of these factors and others will depend on each setting route.

    The titanium alloys are quite satisfactory for biomedical applications due to their physical, mechanical and biological properties. Recent studies focuses on the development of beta type titanium alloys, composed of toxic elements (Nb, Mo, Ta ,...), because they have more advantages than alpha and alpha + beta (Ti- 6Al-4V) alloys such as lower modulus of elasticity, better plasticity and, moreover, the process variables can be controlled to produce selected results. This project focused on the development and characterization of Ti-12Mo-3Nb alloy in the condition 'as cast' and after thermomechanical treatment. The material was characterized in different conditions by X-ray diffraction, optical microscopy, microhardness measurements and elasticity modulus. The results showed that the forged Ti-12Mo-3Nb alloy showed the best combination of properties, being a promising candidate for use as implant. (author)

    Experience gained on systems design, operation, and maintenance, with the increasing degree of complexity, and the growth of computational processing capacity, makes it possible the development of integrated optimization techniques, which take into account the interaction of all involved phases in systems operation. However, such a broad approach, which describes in an integrated way, the involved factors, from the conception of the structure to maintenance policies, makes the problem more complex. Generally, the original problem is cast into a simpler one, by imposing some degree of linearity, which allows for a more conventional treatment. The effect of this linear approach is a sensible increase in the number of variables and constraints to be treated. Another shortcoming is related to the fact that as long as the description of some parameters is allowed to undergo modifications, the resulting model becomes less realistic. This paper presents an integrated optimization method of system performance based on genetic algorithms. The aim is to maximize the benefits from operating a simplified system, where different features, like the structure itself, its design, reliability, redundancy allocation, test and maintenance actions scheduling, and costs, are simultaneously taken into account in an integrated way. The availability model treats the original problem without performing any transformation. The set of solutions generated allows a decision-making support for which budgetary and safety constraints must be considered. The results show that the integrated approach used for optimizing the system is much more convenient and should be applied to more complex systems. (author)

    Inoculation of root nodule bacteria into legume seeds such as soybean [Glycine max. (L.)], common bean (Phaseolus vulgaris L.) and forage pasture has been effective and convenient as this simple procedure may introduce effective strains of Bradyrhizobium/Rhizobium into agricultural soils without a past history of successful cropping systems with the legume hosts. Peat-based substrates previously sterilized have been used for decades as bacteria carrier, protecting them from the prevailing harsh conditions in tropical soils and ensuring their survival with nutrient and protection against the soil antagonists. The Brazilian Government requires that all peat-based substrates must be gamma-sterilized from a cobalt-60 ({sup 60}Co) source, prior the introduction of the root nodule bacteria into the package. The recommendation is for a dose up to 50 kGy for an effective suppression of pathogens and saprophytes, in order to avoid competition among the substrate microbiota. Recently, the use of the electron beam (EB) accelerator has shown to be a new alternative for peat pre-sterilization, as this technique may promote reactive free-radicals which are efficient to suppress microbial contaminants. This fast technology is considered more environment and ecology friendly-sound than gamma radiation ({gamma}). The disadvantage of not reaching higher depth than gamma rays from {sup 60}Co must be considered, and attempts of optimizing the technique are crucial. This study compared both methods by using increasing rates of radiation by {sup 60}Co by the EB method - O, 10, 20, 30, 40 e 50 kGy in a commercial peat used for inoculants. Experimental data from days 7, 14, 21 and 28 days (growth period) and 150, 180 and 210 days (storage period) indicated high numbers of the strain Rhizobium tropici CM-01, labelled with gusA{sup +} (Study 1) and celB{sup +} (Study 2) from both eat-sterilizing techniques, reaching values above the minimum of 1x10{sup 8} cells g{sup -1} peat. At high rates, above 40 kGy, and after long incubation periods (ex. after 150 days), EB method was more efficient to suppress actinobacteria, one serious antagonist for rhizobia. Strain CM-01 celB{sup +}, data for the period of bacterial growth confirmed the efficiency of the method even at rates as low as 10 kGy. (author)

    Some drugs are widely used by the population and can be employed to dose retrospective. The carbohydrates (saccharides), commonly used as excipients in the pharmaceutical industry, produce a quantity of free radicals after gamma irradiation, making them useful for dosimetry in emergency or accident situations that imply in dose evaluation from the materials found nearly or in contact with victims. In general, EPR signal from pulverized pills of some drugs are very complex due to the variety of components in the formulation. Because of this fact, some pharmaceutical excipients identified in the pill composition were also analysed by EPR spectrometry. On the counter drugs were studied: Cebion glucose, AAS, Aspirina, Conmel, Lacto-Purga and sugar substitutive ZeroCal. The excipients were: lactose, amide, anhydrous glucose and magnesium stearate. In some samples the number of radicals produced increased with the dose, showing a linear response for a dose range of interest and an adequate sensibility for dosimetry in accident cases.

    Lymphomas are tumors originated from the transformation of a lymphocyte in the lymphatic system. The most common lymphoma is the Non-Hodgkin Lymphoma (NHL). Advances in immunology and molecular biology have been improving NHL's detection and treatment strategies development, such as Radioimmunotherapy (RIT). Rituximab is an anti-CD20 monoclonal antibody used as immunotherapeutic to treat refractory or relapsed NHL. The goal of the present work was to conjugate this antibody to DOTA-NHS-ester bifunctional chelator and to radiolabel it with {sup 177}Lu radioisotope in order to develop a radio immunotherapeutic agent for NHL's treatment. Different rituximab to DOTA molar ratios (1:5, 1:10, 1:20, 1:50, 1:250, 1:500 and 1:1000) were evaluated in order to determine the best condition for obtaining the highest radiochemical purity of radio immunotherapeutic. The stability of the unlabeled immuno conjugated was evaluated by high performance liquid chromatography (HPLC) for up to 240 days in different storage conditions. The stability of the labeled preparations was evaluated either after storing at 2-8 degree C or incubation in human serum at 37 degree C. The binding to serum proteins was also determined. In vivo studies were performed in healthy Swiss mice, in order to characterize the biological properties of labeled conjugate. Finally, preliminary studies of radio immuno conjugated competitive binding to CD20 positive Raji cells were carried out in order to analyze if the process of conjugation and radiolabeling compromises the immunoreactivity of the antibody. The conjugation applying lower antibody to chelator molar ratios (1:5, 1:10 and 1:20) showed high stability when stored for up to 240 days in different conditions. The HPLC analysis showed that the monoclonal antibody conjugated in molar ratio 1:50 was labeled with higher radiochemical purity (> 95%) when purified in PD-10 column. This conjugate showed reasonable stability at 2-8 degree C. The analysis of the stability in human serum did not suggest high metabolic degradation by serum enzymes. The labeled conjugate showed high serum protein binding, suggesting slow blood clearance, which was confirmed by in vivo studies. The labeled conjugate presented high uptake in the liver, in accordance to biodistribution pattern of monoclonal antibodies. The preliminary competitive binding studies indicated a specific binding and suggest that the synthesis of {sup 177}Lu-DOTA-rituximab did not compromise its binding to CD20 positive tumor cells.

    The problem caused by polymerization shrinkage is critical, because the resin must remain closely in the tooth cavity while gaining rigidity and decrease its dimensions. Forcing the restorative material to distance or to separate the walls of the cavity, the resulting disruption would lead to microleakage, responsible for other problems such as secondary caries, postoperative soreness and may even cause pulpal changes. This process induces the volumetric change of the compound, given by the union of radicals in the formation of the macromolecule (polymer), causing a decrease in volume. This study aimed to develop new experimental composites through the addition of nano components clay minerals in a polymer matrix-based BisGMA / TEGDMA, to evaluate the possibility of a different dimensional behavior during the polymerization. Were used in this study, experimental composites added nanoparticle clay MMT Cloisite 10A (at concentrations of 50, 55, 60, 65 and 70 wt%) and Cloisite 30B (at concentrations of 50, 55, 60 and 65 wt%), which were then compared with the performance of the experimental composites added with micro-particles of silanized silica hybrid Aerosil OX-50 (at concentrations of 50, 60, 65 and 70 wt%). Was used the methods of characterization: Scanning Electron Microscopy (SEM), Thermal-Mechanical Analysis (TMA), Thermogravimetric Analysis (TGA), Differential Scanning Calorimetry (DSC), Absorption Spectroscopy in the Region of the Infrared (FTIR), X-ray Diffraction (XRD), Micro Hardness Knoop, Holographic Interferometry Technique (HIT), Digital Holography (DH), Correlation Image (CI) and Thermography. It was observed that the experimental composites with nanoparticles added clay Cloisite 10A and Cloisite 30B, performed better on tests that measured the polymerization shrinkage (TMA, HIT/HD/IC) and the micro hardness (Knoop), in relation to composites added with Silica Aerosil OX-50. These results may be related to the interaction polymer/clay and the nano composites formation, observed by XRD analysis. Among the nanoparticles studied, the Cloisite 30B showed the most significant results in relation to the nanoparticle Cloisite 10A and this can be attributed to chemical affinity and polar nature of that nanoparticle.

    During the stages prior to installation of a large enterprise, there is an obligation to obtain an environmental license for its effectiveness. However, defining the relevance of an environmental impact generated by changes elapsed in a region, is something subjective, since some variables present qualitative definitions. Aiming to interrelate the variables that influence the environmental impacts in hydroelectric plants, was made the mapping of terms natural resources and degradation of the environment, and its defining variables, based on the theory of fuzzy logic. The construction of fuzzy propositions was based on the manipulation of a rule base, with the 'if' antecedent 'then' consequent structure. It was concluded that the use of fuzzy propositions for the study of environmental impact is an effective method to map the environmental impact caused by construction of a hydroelectric plant, because it defines the degree of influence of impact on the environment.

    The bio stratigraphic studies of the Brazilian sedimentary basins have providing a support for the exploratory research of energetic and mineral resources, in particular at the continental margin. From new discoveries of hydrocarbon accumulations at the Santos and Campos basins, the south portion of the Brazilian continental margin were converted in an important target of the exploration. Therefore, the bio stratigraphic refinement is necessary to detect gaps and to promote an increment on the precision of the lateral correlations in the delimitation and spatial analysis of the potential reservoirs. The actual stage of the bio-chronostratigraphic framework of the Pelotas Basin is presented herein, focusing on its application to the reservoir prospection. The main questions and lacunae on the knowledge are also discussed. In terms of bio stratigraphy, the Pelotas Basin remains poorly evaluated, despite publication of important works on the bio stratigraphy are known since the 1960's. A comparison of bio stratigraphic schemes proposed for the Tertiary section of the basin allows the inference of diverse hiatuses, identified by the absences of bio zones. Hiatuses identified in the {sup 87}Sr/{sup 86}Sr curve, suggest their relationship with discontinuities in the deposition. Discrepancies between the proposed schemes can be attributed to the particular resolution of the different groups used, the variations in the bio stratigraphic criteria and the sampling interval, influencing the bio stratigraphic resolution and therefore its potential as a correlation tool.

    A relevant problem that petroleum companies deal is the estimate of the future levels of reserves The objective of the reserve forecasting is pursued through the construction of mathematical models. Considering that the exploration process is an informed and controlled process, in order to reach the exploration targets, the exploration process is lead inside of a sequence of decisions based on the reached results. Such decisions are taken surrounded by an uncertain environment added to the random nature of the process. Another important assumption that must be taken into consideration is the dependency of the exploration on the conditions, or structure, of the discovered resources and the final potential. The modeling starts with the establishment of a general problem, when the models are being constructed, based on suppositions associated to the main concepts, and ends with the attainment of specific solutions, when the best description, or model, is selected through the estimate of the respective parameters and of the measurement adjustments. The result of this approach reflects the essence of the exploration process and how it is reflected in the incorporation of reserves and history of field discoveries. A case study is used for validation of the models and the estimates. (author)

    On the project of Synchrotron Light Source, silicon-crystal are often used as monochromator and mirrors, to reflect the electrons beam. Silicon is known as a very fragile material, and its optical elements must be designed carefully. Usually, it is bonded in a cooling support made by copper. Thermal contact between the crystal plate and cooling support is made of In-Ga liquid alloy. Due to the difficult of this bonding, brazing tests are being taken with Fe-Ni alloy, in order to improve the silicon mirrors application and performance. Wet ability tests were performed between the silicon plate and commercial fillers. A brazing test was made of silicon and Al12Si, as filler, with Fe-Ni, as base material. Results of microstructure analysis indicated that the braze of a silicon plate is quite promissory. (author)

    SULGAS has developed more judicious systematics investments analysis in the natural gas distribution plants in urban areas . A survey has been made of the variables that influence this type of investment, identifying the most relevant ones. Spread sheet in platform Microsoft Excel and Visual Basic was elaborated that makes possible the deterministic analysis, sensibility, and risk analysis of the projects, through consolidated indicators usable in economic engineering. The great differentiation of this proposal is the possibility/flexibility of the economic impact analysis that each future customer has in the branch where he is linked. The spread sheet presents graphical platforms in which the schematical drawings of the projects are inserted on satellite photos of the region, making possible the projects architectures visualization in parallel with the economic analysis. This graphical platform is tied with the alternatives selected in the economic analysis, being brought up to date the images in accordance with the projects selected in the spread sheet. The risk analysis are carried out through the Monte Carlo simulation, generating investment return probability from each branch, cell, or customer, depending on the criteria defined in the spread sheet. This makes possible the insertion and economic analysis of the factors that can influence the investments in NG distribution system, becoming an important tool in the decision making. (author)

    The use of nuclear techniques, as Neutron Activation Analysis, can be an alternative way for the microbiological diagnosis, bringing a significant profit in the analysis time, for not needing pre cultivated samples in appropriate way. In this technique, the samples are collected and submitted to a thermal neutron beam. The interaction of these neutrons with the samples generates gamma rays whose energy spectre is a characteristic of the elemental composition of these samples. Of this done one, a virus presence can be detected in the sample through the distinction of its respective elemental compositions allowing, also, carrying through the analysis in real time. In this work, computational simulations had been become fulfilled using the radiation transport code based on the Monte Carlo Method, MCNP4B, to verify the viability of the application of this system for the virus particle detection in its natural collection environment.

    Cell cycle blockage in G1 is a mechanism p21 protein-regulated and coupled to DNA damage response to permit genetic content analysis, damage repair and cell death. Analysis of proteins that participates of this response has progressed with new analytic tools, and data contributes to comprehension of radioinduced molecular events as well as to new approaches on practices that employ ionizing radiation. On this perspective, the aim of this research was to evaluate, by flow cytometry, p21 expression on irradiated human lymphocytes, maintained under different experimental conditions. Peripheral blood samples from 10 healthy subjects were irradiated with doses of 0 (non-irradiated), 1, 2 and 4 Gy. Lymphocytes were processed to analysis on ex vivo (no cultured) condition and after 24; 48 and 72 hours culture, with and without phytohemagglutinin stimulation. p21 protein expression levels were measured by flow cytometry, as percentage values. Results indicate that flow cytometric assay allows detection of changes on p21 expression, since it was detected significant increase on phytohemagglutinin-stimulated samples, for all times, against basal expression (ex vivo). However, it was not observed significant alterations on p21 protein radioinduced levels, for all doses, times and culture conditions analyzed. These results not indicate so p21 protein as bioindicator of ionizing radiation exposure. Nevertheless, data confirmation may to require analysis of a more numerous population. (author)

    The Agencia Nacional de Petroleo - ANP - created in 1997 by the petroleum law has the role of regulating oil and natural gas industry activities in Brazil inciting the power self-sufficiency. The petroleum law states the end of petroleum exploration monopoly in Brazil performed by PETROBRAS. Between 1998 and 2004 ANP carried out six bid rounds in brazilian sedimentary basins offered to national and foreign companies. The exploratory activities in Bahia are resulting in commercial discoveries and positive impact to local economy. The petrochemical industry expects the startup of Manati field operation to supply repressed demand of natural gas as fuel and raw material. This article analyzes the legal and institutional processes and economics performances of these activities in Bahia's state. (author)

    The conventional techniques employed to monitor the gasoline quality are expensive, time-consuming and demands on specialized workers to its execution. A study about the applicability of a long period grating, a fiber optic device, as an auxiliary tool for the analysis of Brazilian gasoline conformity is presented in this work. The long period grating spectral response was measured with the device immersed in samples of gasoline A with different proportions of hydrated ethyl alcohol fuel. A resolution of 0.23 % was obtained for the concentrations range of commercial interest, between 20 % and 40 %. The device performance was also tested with a set of conform and non-conform gasoline C samples. The device spectral response for these samples, as well as the samples densities and the conformity status were employed to train and to validate an artificial neural network with radial base function. The obtained results show that fiber optic sensors supervised by artificial neural networks can constitute systems for smart measurement with high applicability in the analyses of gasoline conformity, reducing costs and time related to conventional tests.

    Textile industry is one raising commercial activity in Brazil. This activity has been generating important environmental interferences such as colour and bad biological effects into aquatic environment. Liquid textile effluents are toxic to lived organisms and may present low biological degradability. Although foreseen at federal regulation, the effluent quality is not controlled by toxicity assays in the country. These assays are carried out to determine the potential effects of chemical substances and effluents to cause negative effects to the exposed organisms. The present work aimed whole toxicity evaluation as well as the applicability of two different treatment techniques: ionizing radiation and zeolite adsorption. The efficacy of them were evaluated using eco toxicity bases and real effluents. Two different industries from Sao Paulo State contributed to this project supplying their real effluents. The samples were collected at a Textile Industry and at a Chemical Industry (dying producer) and after the measurement of whole toxicity the samples were submitted to treatments. Toxicity assays were carried out for Daphnia similis and for Vibrio fischeri. Sample irradiations were performed at an Electron Beam Accelerator at CTR/IPEN. Zeolites treatment is an P and D activity from CQMA/IPEN which contributed to this Project. Zeolites v/ere prepared from fly ash previously being used as an adsorber material. Both treatments (electron irradiation and zeolite adsorption) resulted on important toxicity and colour reduction. Concerning irradiation the effluents from chemical industry required higher radiation doses than that from textile activity. The radiation dose to be suggested is 40 kGy (toxicity reduction > 60%) for the chemical effluents and 0.5 kGy for the textile effluents (toxicity reduction > 90%). When zeolite adsorption was evaluated the Z1M6 resulted in 85%o v/hole toxicity reduction and ZC6 resulted in very low efficiency for the effluents of chemical industry. (author)

    Due to increasing worldwide shortage of food and energy sources, sugarcane bagasse has been considered as a substrate for single cell protein, animal feed, and renewable energy production. Sugarcane bagasse generally contain up to 45% glucose polymer cellulose, much of which is in a crystalline structure, 40% hemicelluloses, an amorphous polymer usually composed of xylose, arabinose, galactose, glucose, and mannose and 20% lignin, which cannot be easily separated into readily usable components due to their recalcitrant nature. Pure cellulose is readily depolymerised by radiation, but in biomass the cellulose is intimately bonded with lignin, that protect it from radiation effects. The objective of this study was the evaluation of the electron beam irradiation efficiency as a pre-treatment to enzymatic hydrolysis of cellulose in order to facilitate its fermentation and improves the production of ethanol biofuel. Samples of sugarcane bagasse were obtained in sugar/ethanol Mill sited in Piracicaba, Brazil, and were irradiated using Radiation Dynamics Electron Beam Accelerator with 1,5 MeV energy and 37 kW, in batch systems. The applied absorbed doses of the fist sampling, Bagasse A, were 20 kGy, 50 kGy, 10 0 kGy and 200 kGy. After the evaluation the preliminary obtained results, it was applied lower absorbed doses in the second assay: 5 kGy, 10 kGy, 20 kGy, 30 kGy, 50 kGy, 70 kGy, 100 kGy and 150 kGy. The electron beam processing took to changes in the sugarcane bagasse structure and composition, lignin and cellulose cleavage. The yield of enzymatic hydrolyzes of cellulose in. (author)

    The energetic analysis is the traditional method of quantification of the energy used in an operation involving physical and chemical processes and transference and/or conversion of energy. Generally used through energetic balance that is based on the first law of thermodynamics to evaluate the energetic efficiency. This balance is used to determine and reduce the loss of energy. Although an energy balance does not provide information about the energy degradation or resources during a process and do not quantify the potential or quality of the energy fluxes and material that flow in a system and come out as products and losses. The exergetic analysis goes beyond the limitations of the first law of thermodynamics. The concept of exergy is based in the second law of thermodynamics. The objective of this paper is to compare the more suitable analysis method aiming the identification of the energy economy potentials and consequently the reduction in the emissions of the greenhouse gases, through the balance of mass, energy and exergy of the blast furnace 1 of V and M do Brazil.

    The {sup 1}H NMR data set of a series of 3-aryl (1,2,4)-oxadiazole-5-carbohydrazide benzylidene derivatives synthesized in our group was analyzed using the chemometric technique of principal component analysis (PCA). Using the original 1H NMR data PCA allowed identifying some misassignments of the proton aromatic chemical shifts. As a consequence of this multivariate analysis, nuclear Overhauser difference experiments were performed to investigate the ambiguity of other assignments of the ortho and meta aromatic hydrogens for the compound with the bromine substituent. The effect of the 1,2,4-oxadiazole group as an electron acceptor, mainly for the hydrogens 12,13, has been highlighted. (author)

    Toxic metals, such as Ni, V, Zn, Cu, Cr, Mn and metalloids as As and Se and their compounds are mainly associated with the smaller diameter particulates present in the atmospheric aerosols. This fact is important, principally, when it concerns public health, because this is considered the breathable fraction of particles that can penetrate deeply into the lungs and cause damage to the alveoli. Once in the atmosphere the concentrations of trace metals, in general, show very low levels, thus the determination of the elementary composition of those particles requires the use of appropriate analytical techniques such as Particle Induced X-Ray Emission (PIXE), Neutron Activation Analysis (NAA) and X-Rays Fluorescence spectrometry (XRF), among others. The main objective of this study was the identification of the generating sources of gross (PM{sub 10}) and fine (PM{sub 2.5}) particles present in the atmospheric aerosols of the metropolitan region of Belo Horizonte. Neutron Activation Analyses by k{sub 0}-method (k0NAA) combined with energy dispersed by X-ray fluorescence was used to measurement of the concentration of trace elements present in each sample. High levels of particulate concentrations, especially PM{sub 2.5}, were measured during the sampling period. In general, the air quality varied from Reasonable to Inadequate. The receptor model used to assist in the identification of the main emission sources was the Principal Components Analysis. The results showed that the main elements presents in particulate inhalable matter (PM{sub 2.5} and PM{sub 10}) were Ag, Al, As, Au, Ba, Br, Ca, Cl, Cr, Cu, Fe, K, Mn, Na, S, Sb, Sc, Si, Ti, W and Zn. The results for multi-variable analyses shown clearly four pollutant sources, these being: vehicular emissions; resuspended soil/asphalt powder; secondary aerosols associated with emission of SO{sub 2} and industrial emissions associated with fossil oil burning.

    According to the report of the International Agency for Research on Cancer, the growth of this disease implies the death of 17 million people a year by 2030. Although the knowledge on development of cancer is growing considerably, just a few advances in the diagnosis and therapy has been achieved. Faced with this scenario, it is clear the need for new substances more specifics with low toxicity to the patient, which can be used for diagnosis and treatment of cancer. Membrane receptors over expressed in tumor cells are promising target candidates for development of diagnostic and therapeutical tools. Integrins are a family of hetero dimeric cell surface adhesion receptors able to recognize and bind to proteins in the extracellular matrix (ECM). This recognition is mainly through the RGD domains presents in both the cell surface as in the protein from the ECM. Various integrins have been identified as regulators of tumor progression. The RGD domain is also found in some snake venoms named disintegrins. Disintegrins inhibit cell-matrix and a cell-cell interactions mediated by integrins and it has been shown that these proteins are able to inhibit metastasis in processes dependent on integrin. The disintegrin-like (ECD), as well as RGD-disintegrin are also able to bind to cell surface integrins and inhibit their adhesion to the natural ligands. In this work it was purified from Bothrops leucurus venom (VBL), a metalloproteinase-class P-III with disintegrin-like domain (ECD), Leucurolisina B (Leuc-B). This metalloproteinase and the crude venom were used to evaluate their applicability in the differential detection of tumors. In vitro results demonstrated that both VBL and Leuc-B have potent antitumoral effect on several cancer cell lines: U87, T98, RT2 (glioblastoma), MCF7 (breast), Ehrlich and UACC (melanoma) with IC{sub 50} values of approximately 0.6 muM. The morphological changes observed in these strains when treated with Leuc-B, and data from the DAPI staining solution and acridine/ethidium bromide indicate that the antitumoral effect of these substances occurs via apoptosis. Radioactive probes of Leuc-B ({sup 131}/{sup 125}I-Leuc-B) were synthesized with high specific activity and high radiochemical purity. Biodistribution studies, performed by intravenous injection and intratumoral flow in mice bearing Ehrlich tumor showed a significant tumor uptake Leuc-B ( p <0.05). These results show the potential of Leuc-B as a template for the development of drugs and radiopharmaceuticals for diagnosis and therapy of tumors. (author

    It is not an easy task to frame uncertainty measurement problems by means of differential equations quickly and satisfactorily. Therefore, it is necessary to adapt the method for data representation by conditional fuzzy propositions for modeling uncertainties measurement and their effect on the propagation. This method provides a parametric adjustment for fuzzy sets of assumptions, and the functions of consequence of each rule in the manner of a parable. The paper introduces concepts of sources of errors in measures, fundamentals of fuzzy logic, description of the algorithm method, application to error detection and representation of global uncertainty.

    This study integrates palynofacies analyses and the sedimentological and stratigraphic model of the Oligo-Miocene/Miocene siliciclastic deposits from the stratigraphic interval of the shallow continental platform up to the slope/basin of the Oligo-Miocene/ Miocene of the Campos Basin proposed. The main objective of the palynofacies study was to characterize the particulate sedimentary organic matter to obtain information about the proximal-distal relationship and the sedimentary organic matter preservation and depositional environmental conditions. The 158 core samples collected in 29 wells of the 9 oil production fields (Albacora, Barracuda, Marlim Sul, Marlim, Voador, Marlim Leste, Moreia and Albacora Leste), were studied. This technique provides information about the proximal-distal relationship and the paleoenvironmental conditions of deposition and preservation of sedimentary organic matter, to facilitate the evaluation and comparisons between the associations of particulate organic components. Thus, the palynofacies technique can be used as another tool in the characterization of depositional systems, based on the spatial and temporal distribution of sedimentary intervals. In general the palynofacies assemblages showed the predominance of the Phytoclast Group (terrestrial derived organic matter) at various degradation stages due to the selective preservation process diagnosed in the studied samples. Some samples, revealed high dinocysts percentages indicative of transgressive depositional conditions. From the obtained data, it was possible to characterize the stratigraphic sequences according to the distribution of particulate organic content (e.g. influence of fluvio-deltaic systems, oxygen system, regressive-transgressive tendencies of each sequence). Additional analyses of Total Organic Carbon (% wt) showed the control of the particulate components from the Phytoclast Group on the TOC (% wt) content, suggesting that the relative sea-level variation curves can be drawn inversely to the TOC content variation curves along the sequences, since siliciclastic progradation always presents a correlation with the absolute abundance of the terrestrial organic matter.

    The temperature increase in root dentine irradiated by Er:YAG laser beam was analyzed, for different dentine thickness and different energy and frequency conditions, aiming the evaluation of Er:YAG laser in endodontic therapy, without causing any damages to close tissues. Twenty four human teeth were separated in four groups with six teeth each, and longitudinally sectioned in thickness of 0.5 mm (first group), 1,0 mm (second group), 1,5 mm (third group) and 2,0 mm (fourth group). Those samples were irradiated with the Er:YAG laser, emitting at the wavelength of 2.94{mu}m, by using a sapphire optic fiber with diameter of 0.375 mm, and forming an angle of 5 deg with the irradiated dentine surface. Three different laser energies were used in this study, 180 mJ, 160 mJ and 140 mJ, with frequencies of 10 Hz and 15 Hz. The temperature data were collected in a digital-analog system and sent to a computer for analysis. It was verified that the time for temperature increases of 5 deg in the external root walls varies according to the laser energy, repetition rate and dentine root thickness. Thus, in this work we could obtain laser parameters to avoid thermal damages in periodontal tissues. (author)

    The hydroelectric projects have been the main form to supply the energy demand in Brazil. Although it has been considered a way of clean generation, it brings many environmental impacts. Due to the fact that inconsistencies in environmental impact studies often occur, this study aimed to evaluate the quality of environmental diagnosis of the mammals in SHP in the Espirito Santo. Therefore, was notice an insufficient data survey, because of the relevance given to the secondary data and the lack of seasonal investigations, bringing damages to the proposals submitted of environmental compensation. This way, manners ware proposed that aim to improve the quality of these studies, which include since environmental awareness programs at the penalizing of those involved in such studies. (author)

    Rating agencies have strong influence on the international financial market for both public and private debt. Host countries also have due influence on local enterprises, by means of the macro economic policy. In the case of default of sovereign debt or capital controls, domestic firms may have serious difficulties in meeting their obligations in foreign currency. This explained the so called sovereign ceiling to the corporate ratings. This explicit ceiling has been abandoned by the main rating agencies, as some corporations may have more means to meet their debt than sovereigns. Oil companies are a good example. This paper aims to explain the variables that help explain the Brazilian sovereign ratings and PETROBRAS ratings, using the ordered logit method, with emphasis on the factors that influenced the piercing of the severing ceiling by PETROBRAS in 2001.

    Angola is in the spot light lately as one of the major oil producers in the world, being the second largest oil producer in Africa. Therefore, in 2007, this country became a member of OPEC which brought to table several speculations concerning Angola's position facing the pressures and demands of an international organization. This article comes to analyse Angola's possible strategies when it comes to defending its economic interests and its participation in the price politics implemented by OPEC. All hypotheses considered in this article are analysed according to the Complex Interdependence Theory (Keohane and Nye). This International Affairs Theory is defined by a mutual and multilateral dependence between the nations. This way, we may conclude that even though Angola has a history of non fulfilling its agreements, the cooperation is made necessary because it is the most benefice alternative. The tendency is that when Angola starts fulfilling its quotas on the oil matter it will receive cooperation from OPEC and other nations in other areas where this country needs assistance. (author)

    Natural circulation loops apply to many engineering applications such as: water heating solar energy system (thermo-siphons), thermal management of electrical components (voltage converter), geothermal energy, nuclear reactors, etc. In pressurized water nuclear reactors, known as PWR's, the natural circulation loops are employed to ensure passive safety. In critical situations, the heat transfer will occur only by natural convection, without any external control or mechanical devices. This feature is desired and has been considered in modern nuclear reactor projects. This work consists of a numerical study of the natural circulation loop, located at the Instituto de Pesquisas Energeticas e Nucleares / Comissao Nacional de Energia Nuclear in Sao Paulo, Brazil, in order to establish the flow pattern in single phase conditions. The comparison of numerical results to experiments in transient condition revealed significant deviations for the Zero Equation turbulence model. Intermediate deviations for the Eddy Viscosity Turbulence Equation (EVTE), k - {omega}, SST e SSG models. And the best results are obtained by the k - {epsilon} e DES models (with better results for the k - {epsilon} model). (author)

    Many of hydrocarbon reserves existing in the world are formed by heavy oils (deg API between 10 and 20). Moreover, several heavy oil fields are mature and, thus, offer great challenges for oil industry. Among the thermal methods used to recover these resources, steam flooding has been the main economically viable alternative. Latent heat carried by steam heats the reservoir, reducing oil viscosity and facilitating the production. This method has many variations and has been studied both theoretically and experimentally (in pilot projects and in full field applications). In order to increase oil recovery and reduce steam injection costs, the injection of alternative fluid has been used on three main ways: alternately, co-injected with steam and after steam injection interruption. The main objective of these injection systems is to reduce the amount of heat supplied to the reservoir, using cheaper fluids and maintaining the same oil production levels. In this paper, the use of N{sub 2} as an alternative fluid to the steam was investigated. The analyzed parameters were oil recoveries and net cumulative oil productions. The reservoir simulation model corresponds to an oil reservoir of 100 m x 100 m x 28 m size, on a Cartesian coordinates system (x, y and z directions). It is a semi synthetic model with some reservoir data similar to those found in Potiguar Basin, Brazil. All studied cases were done using the simulator STARS from CMG (Computer Modelling Group, version 2009.10). It was found that N{sub 2} injection after steam injection interruption achieved the highest net cumulative oil compared to others injection system. Moreover, it was observed that N2 as alternative fluid to steam did not present increase on oil recovery. (author)

    Efficient hole cleaning is still a challenge in well bore drilling to produce oil and gas. The critical point is the horizontal drilling that inherently tends to form a bed of sediment particles at the well bottom during drilling. The cuttings bed erosion depends mainly on the shear stress promoted by the drilling fluid flow. The shear stress required to cause drag in the cuttings bed is investigated according to the fluid and particles properties, using an experimental assembly, composed of: a system for fluid circulation, a particle box, a pump system and measuring equipment. The observation area is a box below the flow line in an acrylic duct used to calibrate sand particles. The test starts with the pumps in a low frequency which is increased in steps. At each frequency level, images are captured of carried particles and the established flow rate is recorded. The images are analyzed when the dragged particle is no longer random and sporadic, but becomes permanent. The shear stress is identified by the PKN correlation (by Prandtl, von Karman, and Nikuradse) for the minimum flow rate necessary to cause drag. Results were obtained for just water and water-glycerin solution flows. (author)

    This work describes the geometric and kinematic characteristics of the Major Gercino Shear Zone (MGSZ) in the Canelinha-Garcia area. This shear zone is one of the major lineaments that affect all southern Brazilian precambrian terrains. In Santa Catarina State, it separates, along its whole extension, the supracrustal rocks of the Brusque belt (northern part) from the Granitoid belt (southern). This zone is characterized by a regional NE trend and a dextral sense of movement where ductile-brittle structures predominate. The MGSZ is composed of two mylonitic belts separated by granitoid rocks probably associated to the development of the shear zone. Both shear zones show cataclastic to ultra mylonitic rocks, but mylonites and protomylonites conditions at high strain rate. The calc-alkaline granitoids present in the area can be grouped in two granitoid associations with meta to peraluminous affinities. The Rolador Granitoid Association is characterized by grayish porphyritic biotite-monzogranites and the Fernandes Granitoid Association by coarsed-grained to porphyritic pinkish amphibole-syenogranites. The U-Pb and Rb-Sr ages range from 670 to 590 Ma with the Sr{sup 87} / Sr{sup 86} initial ratios suggesting a crustal contribution in the generation of these rocks. The importance of the pure shear component is also emphasized by the results of the Fry method. Many z axes of the strain ellipses are at high angle to the shear foliation. Symmetric porphyroclasts also corroborate this hypothesis. The micaceous minerals formed during the shear development indicate K-Ar ages around 555 {+-} 15 Ma. Brittle reactivations of the shear zone have been placed by K-Ar in fine-fraction materials at Triassic time (215 {+-} 15 Ma.) 220 refs., 107 figs., 18 tabs., 4 maps

    This study presents the characterization of the external geometry of deltaic oil reservoirs, including the description of their areal distribution using geo statistic tools, such as variography and kriging. A high-resolution stratigraphic study was developed over a 25 km{sup 2} area, by using data from 276 closely-spaced wells of an oil-producer field from the Reconcavo Basin, northeastern Brazil. The studied succession records the progressive lacustrine transgression of a deltaic environment. Core data and stratigraphic cross sections suggest that the oil reservoirs are mostly amalgamated, delta-front lobes, and subordinately, crevasse deposits. Some important geometrical elements were recognized by the detailed variographic analysis developed for each stratigraphic unit (zone). The average width for the groups of deltaic lobes of one zone was measured from the variographic feature informally named as hole effect. This procedure was not possible for the other zones due to the intense lateral amalgamation of sandstones, indicated by many variographic nested structures. Net sand krigged maps for the main zones suggest a NNW-SSE orientation for the deltaic lobes, as also their common amalgamation and compensation arrangements. High-resolution stratigraphic analyses should include a more regional characterization of the depositional system that comprises the studied succession. On the other hand, geostatistical studies should be developed only after the recognition of the depositional processes acting in the study area and the geological meaning of the variable to be treated, including its spatial variability scales as a function of sand body thickness, orientation and amalgamation.

    Human hair analysis studies have been subject of continuous interest due to the fact that they can be used as an important tool to evaluate trace element levels in the human body. These determinations have been carried out to use hair for environmental and occupational monitoring, to identify intoxication or poisoning by toxic metals, to assess nutritional status, to diagnose and to prevent diseases and in forensic sciences. Although hair analysis presents several advantages over other human tissue or fluid analyses, such as organ tissue, blood, urine and saliva, there are some controversies regarding the use of hair analysis data. These controversies arise from the fact that it is difficult to establish reliable reference values for trace elements in hair. The purpose of this study was to evaluate the factors that affect element concentrations in hair samples from a population considered healthy and residing in the Sao Paulo metropolitan area. The collected human head hair was cut in small pieces, washed, dried and analyzed by neutron activation analysis (NAA). Aliquots of hair samples and synthetic elemental standards were irradiated at the IEA-R1 nuclear research reactor for 16 h under a thermal neutron flux of about 5x10{sup 12} n cm{sup -2} s{sup -1} for As, Br, Ca, Co, Cr, Cs, Cu, Fe, K, La, Na, Sb, Sc, Se and Zn determinations. The induced gamma activities of the standards and samples were measured using a gamma ray spectrometer coupled to an hiperpure Ge detector. For quality control of the results, IAEA- 85 Human Hair and INCT-TL-1 Tea Leaves certified reference materials (CRMs) were analyzed. Results obtained in these CRMs presented for most of elements, good agreement with the values of the certificates (relative errors less than 10%) and good precision (variation coefficients less than 13.6%). Results of replicate hair sample analysis showed good reproducibility indicating homogeneity of the prepared sample. Results obtained in the analyses of dyed and non-dyed hair showed that element adsorption or desorption occurs due to the dye. Analysis of hair samples collected from different regions of the head presented significant differences for the elements Fe, Sc, Se and Cr, indicating the importance of defining head regions for hair sample collection. Results of hair analysis from individuals residing in Sao Paulo metropolitan area showed individual differences for age, gender and natural hair color. Results obtained in this population also showed, that the mean element concentrations found are within the literature values. (author)

    Many professional geologists are not familiar with the origin of certain concepts. This is the reason that when making references, they do not give credit to the real authors. This paper recovers a paper which is essential to understand the evolution of the Brazilian sedimentary basins. This article was first published in 1972 and it was the first one based on plate tectonics which developed a more global vision on the evolution of the basins known up to that time. In some details it is outdated, many interpretations have changed, but the basic ideas about the evolution of the basins are accepted and used today. It should be remembered that the present data were not available and some features - e.g the Pendencia Graben - were unknown; it was the very beginning of basin exploration such as in the Campos and Santos basins. The interpretation premises of the work were developed by a team of geologists working at the SETUP (today CEN-NOR) in Bahia. In the following year, a summary of the original report was presented during the 26th Congress of the Brazilian Geological Society (SBG) held in Belem (Para State). Due to a fault of the organizing committee, the paper was not published in the Congress proceedings, it was only printed as internal reports produced by the DIDEP/SETUP/BA (1972) and the DEXPRO/Rio (1972). In order to publish this paper in the BGP, an attempt was made to maintain the original form, as it should had been printed in the Congress proceedings. Also, in order to make editing easier, figures 11 and 12, the stratigraphic tables for the main Brazilian basins and their African correlates are not being published. It is believed that the understanding of the work will not be affected. We hope that other important papers that are unknown to Brazilian geologists can be restored. The Brazilian and Western African coastlines were orientated by the ancient structural lines. In the Upper Jurassic, continental deposits were accumulated within the Afro-Brazilian trough, extending from the Alagoas-Cameroun to the Almada-Congo areas. The Wealden reactivation established the coastlines along the rift valleys. The first one, from south to north, along the underlying alignments, and the second, from west to east, cutting across and giving rise to a series of lakes. During the Aptian, the first marine transgressions took place, building up two proto-oceanic gulfs. One of them, bounded by the Walvis- Rio Grande and the Pernambuco-Cameroun proto chains, favored the deposition of thick evaporites deposits. To the north, the second gulf maintained an open connection with the ocean. From the Albian to the Turonian, the two continents remained linked. However, due to the progressive separation of the plates, pulsation transgressions took place until full marine conditions were attained. The rupture of the last link between the two plates was during the Turonian and the Santonian. Shearing stresses occurred along the Brazilian northeastern and the Gulf of Guinea coasts, caused by the trans current displacement of the two plates. However, to the south of Pernambuco-Cameroun, tension stresses were always registered while the continents were migrating. When both plates were completely free, the African plate was released from the tension stress, giving rise to the compression of the Benue trough. During the Cenozoic, the uplift of continental belts, adjacent to the coasts, supplied the continental margins and intracratonic basins with sediments. (author)

    The natural gas pipeline network grows around the world, but its operation inherently imposes a risk to the people living next to pipelines. Due to this, it is necessary to conduct a risk analysis during the environmental licensing in Brazil. Despite the risk analysis methodology is well established, some points of its application for the distribution pipelines are still under discussion. This paper presents a methodology that examines the influences of major projects and operating parameters on the risk calculation of a distribution pipeline accident in urban areas as well as the possible accident scenarios assessment complexity. The impact of some scenarios has been evaluated using a Computational Fluid Dynamics tool. The results indicate that, under certain conditions, the risks from the pipeline operation under operating pressures of 20 bar may be acceptable in location class 3 or even in class 4. These results play a very important role if management decisions on the growth of the distribution of natural gas network in densely populated areas as well as in the improvement of laws to control the activity of distribution of natural gas.

    Residential consumers represent a significant part of the market of electric energy and are increasing by deriving tributes of the tariff of energy. These consumers are uninformed about the abuses that happen to them. This work has as objective to analyze and to argue the behavior of the tariffs of energy in the period of 2002 the 2006, demonstrating the occurred increases and pointing a relation enters the rise of the price of this energy and the increase of the number of clandestine linkings and difficulty to hold the basics statements of actually electrical regiments. ANEEL's data show that in 1995 the tariff for class residential was R$ 76.26 and industrial was R$ 43.59; in 2003 passed respectively to R$ 236.34 and R$ 110.48. This analysis is directly related to the difficulty of obtaining a national energy management totally sustainable. (author)

    The demand for alternative sources of energy has grown in recent years in line with the variation of petroleum prices coupled with the recent energy crisis. Through anaerobic digestion swine manure can be converted into biogas. In the present study it was evaluated the economic viability of using biogas as an alternative source for the production of electricity, for different periods of generation. The method used for the economic evaluation was the net present value (NPV). The time of return on invested capital was also calculated taking into account the discount interest rate on cash flows. The study proved to be economically viable use of biogas from swine manure as a source for generating electricity. The increased demand for electricity in the property increases the net present value and decreases the time required for return of the investment. (author)

    The typical manifestations of neurocysticercosis are described widely in the literature. The purpose of this study is to demonstrate the uncommon presentations of different forms of neurocysticercosis in MR imaging. A retrospective analysis of 172 cases of neurocysticercosis in MR studies was carried out over a period of 13 years. One hundred and four males and 68 females with a mean age of 32 {+-} 3.7 years were studied. The studies were performed on 1.5 T G E MR units and T1 was used before and after gadolinium injection, T2 and gradient-echo (T2*) sequences. The authors divided the unusual manifestations of neurocysticercosis into: intraventricular, subarachnoid, spinal, orbital, intra parenchymatous, and reactivation of previously calcified lesions. The results obtained were: intra parenchymatous 95 cases (55.23%); intraventricular 27 cases (15.69%); subarachnoid 20 cases (11.63%); spinal 6 cases (3.49%); orbital 1 case (0.58%); reactivated lesion 1 case (0.58%); association of intraventricular and intra parenchymatous 12 cases (6.98%); association of subarachnoid and intra parenchymatous 6 cases (3.49%); association of subarachnoid and intraventricular, 4 cases (2.32%). MR imaging is a sensitive and specific method in the analysis of different forms of unusual manifestations of neurocysticercosis, which should appear in the differential diagnosis of parenchymal, ventricular, spinal, cysternal, and orbital lesions.

    The main application of image-guided radiotherapy (IGRT) in the cancer prostate treatment is to ensure the delivery of the prescribed dose to the tumor. With the modality cone beam computed tomography (CBCT) prostate, seminal vesicles, bladder and rectum can be previewed before each treatment and the actual dose delivered to these organs can be controlled, through the alignment of patient isocenter. The aim of this study was to analyze the tumor coverage and dose to organs at risk effectively obtained during the patient's treatment. Three patients with prostate cancer were treated with intensity modulated radiotherapy (IMRT) or volumetric modulated arc radiotherapy (VMAT) techniques with 74 Gy and 2 Gy per fraction. It was performed daily isocenter location of the prostate with CBCT. A radioncologist drew the clinical target volume (CTV), rectum and bladder in CBCT's and treatment fields were applied retrospectively in each CBCT for dose calculation. For the CTV it was considered the D95 (dose that covers 95% of the volume), for the rectum V50 (volume receiving 50 Gy), V60, V65 and V70 and for bladder V65 and V70. The average D95 of the prostate after the offset was 202 cGy, the V50, V60 and V65 of the rectum for one patient was reduced by 9.6%, 16.6% and 31%, respectively, and V65 of the bladder to another patient was also reduced by 3.5% in IGRT. The results showed that the use of IGRT provided a reduction in the irradiated volume of healthy organs. Thus it is concluded that the use of daily CBCT allows reproducibility of treatment, reducing delayed toxicities and increasing the probability of tumor control. (author)

    The Earth receives annually 1,5.1018 kWh of solar energy, which corresponds to 1000 times the world energy consumption in this period. This fact comes out that, besides being responsible for the maintenance of life on Earth, the solar radiation is in an inexhaustible energy source, with an enormous potential for use by systems capture and conversion into another form of energy. In many applications of low power systems that convert light directly into electricity, called photovoltaic advantageously replace other means of production processes, where its distribution is very significant. The determination of the power generated by such a system is of paramount importance for the design energy of its implementation and evaluation of the system itself. This study aims to determine a relationship between the maximum power generated by solar photovoltaic and characteristic parameters of the generator. This relationship allows to evaluate the performance of such a system. For simulations of the developed equations were used 3 photovoltaic modules with an output of 100 Wp each, and data collection was performed during one year by enrolling in addition to meteorological data, solar irradiance incident on the modules.

    The aim of this work is to contribute to the research in the reconstruction of part of the pre-history of the Amazon Basin by means of an analytical methods combined with multivariate analysis, given a analytic basis that can be continued by the archaeological work, through the identification, classification, provenance and dating the ceramics found in different archaeological sites of the Hydro graphic Basin of the Purus river. Neutron activation analysis in conjunction multivariate statistical methods were used for the identification and classification and thermoluminescence was used for the dating. Chemical composition results were in better agreement with archaeological classification for the archaeologically define Iquiri, Quinan and Xapuri phases and less characteristics the Iaco and Jacuru archaeological phase were not well characterized. An homogeneous group was established by most of the samples collected from the Los Angeles Archaeological Site (LA) and was distinct from all the other groups analysed. The provenance studies made with ceramics collected at this site shows that they were made with clay from nearby river (Rio Ina). From the LA ceramics dating the average date of site occupation was 1660 years. The ceramic dating results from the external wall of a circular earth wall construction confirm the relation with the local pre-history. Beyond the Acre material two urns were dated from the Archaeological Site Morro Grande and Sao Jose at Araruama, Rio de Janeiro. (author)

    In this work nitrided layers deposited on austenitic and super austenitic stainless steels were analyzed through optical microscopy and X-rays diffraction analysis (XRD). It was observed that the formation of N supersaturated phase, called expanded austenite, has promoted significant increment of hardness (> 1000HV). XRD results have indicated the anomalous displacement of the diffracted peaks, in comparison with the normal austenite. This behavior, combined with peaks broadening, it was analyzed in different nitriding temperatures which results showed good agreement with the literature. (author)

    The present work discusses about the selection of the best sand control method to be adopted for offshore operations according to a specific technologic limitation and by demands imposed by the environment in which it is used. First of all, the paper mentions the phenomena of solids carrying. Then the source environments of the study are analyzed. This approach is considered important because it is the basis for understanding the final part of the research, composed of the method/environment correlation. Three fictitious offshore fields based on real data are presented. In each of them, two wells are studied, one cased, and one open holed. Parameters like permeability and UCS have the same conceptual relevance as the sand control methods presented. The analysis of methods follows those used for the environments. The following methods are presented: by restriction of solids flow, by drag strength reduction and by increase of cohesion strength. Emphasis is given on mechanic methods. Finally, this study concludes its initial purpose, which is selecting the best sand control method for each well, substantiating in each one, the reason for the choice. (author)

    The oil activities in Brazil had been started in an intensive way by the years 30 and 40. During approximately 40 years only one agent had been executed the oil activities in this country: the PETROBRAS. Many of the fields explored in the past are nowadays in decline. These fields, not interesting for the majors, would be interesting for the small and medium enterprises. The present research analyses the mature oil fields and its regulation in Brazil, looking to the 'Constituicao Federal de 1988' and to the idea of social and economic development. (author)

    Objective: The aim of this study was to quantitatively evaluate the histological changes produced by radiation therapy both on the stroma and the parenchyma of submandibular gland in rats. Materials and methods: The sample size consisted of 30 Wistar rats, divided in two groups: test and control. The 15 animals of the test group were irradiated daily on the head and neck region with a dose of 2 Gy for six weeks using a rotational fractionated modality of {sup 60}Co-gamma rays. At the end of the experimental period the animals had received a total dose of 60 Gy. Sixty hours after the last radiation therapy session the submandibular glands of the animals from both groups were excised, processed using paraffin technique, stained with hematoxyline-eosin and analyzed by optical microscopy. Results: The mean proportional volume of the glandular parenchyma and stroma was obtained using a stereological method of manual point counting. The proportional volume of the acini on the irradiated group (60.67%{+-}6.43) was significantly lower than the control group (67.42%{+-}10.90) (p = 0.048), however there was no statistical difference between the groups for parenchyma, ducts and stroma (Student t test, p > 0.05). Conclusion: The radiation therapy produced acinar atrophy in submandibular glands. No total quantitative changes in the stroma or in the parenchyma were observed. (author)

    In the last decades, the intensive and no rational use of energy resources from fossil fuels has been causing climatic changes, due to the increase in air pollutants, mainly Co2. The production of liquid fuels from biomass stands out as one of the principal energy alternatives with low environmental impact that could substitute the fuels derived from petroleum in the transportation section. The present work shows a revision from the main Life Cycle Analysis (LCA) studies performed for biofuel production by BTL (Biomass to Liquid) route. In this revision, it is possible to identify some of the main environmental impacts associated with this type of fuel production, as a function of the energy and material required to its production. Likewise, it is possible to elaborate recommendations in fuel production that allow the increase of benefits to the environment. (author)

    Brazil impels its economy again. A development expected in 80 and 90 years it is real. This growth demands new technologies, new researches and bases that bear that growth. Electric power is in these bases, but Brazil is not ready for that. Electric power cogeneration possibility appears, using sugar cane bagasse. Alcohol and sugar plants have already that practice working with a low generation volume. With some investment this volume can be increased, adding about 10% to national energetic matrix. The aim of this work is to present a short time alternative for national electric matrix. It shows the energetic situation of the country, some experiences already implanted in some countries around the world and some options for equipment improvement used in alcohol and sugar plants. It is shown alternatives sources of electric power generation studied on Brazil, as well as the planning of National Energetic Program of ELETROBRAS. It analyses, in details, sugar cane bagasse use, which is used in Sao Paulo plants to generate electric power. Possible systems and troubles for its implantation in sugar and alcohol plants are discussed. (author)

    Currently there are few applications on the risk analysis procedures related to radiotherapy, mainly in the practice of brachytherapy. The objective of this study was to analyze the perception of risk levels, present in the practice of high dose rate brachytherapy (HDR), using a form based on the concept of the risk matrix and a database (SEVRRA) containing information about the processes related to routine brachytherapy. A form containing information regarding the brachytherapy procedure HDR and an attachment indicating how to complete it properly was delivered to a medical physicist of each service/institution. The reference value for the risk levels found, considered acceptable for all performed analyzes, was set at a percentage limit of 33% (assuming a failure in each 3 existing processes). The results showed that the overall risk analysis showed a value for average percentage of prioritized risk of 18% below the recommended range. About the analyzed groups, the higher average percentage of relative risk was found less than 12% of the recommended range, associated with the group of patients. On existing steps, the highest average percentage of relative risk was found less than 1% of the recommended range, associated with stage records and treatment planning. This study showed that although this procedure does not have a large history of accidents, still poses risks considerable that must be managed with great accuracy and immediate action to an effective decrease these risk percentages.

    The surgical treatment of gastric cancer has better long-term survival rates when performed in patients with early gastric cancer. Worse results are obtained in treatment of advanced gastric cancer. Most patients in west centers are treated in advanced stages. A great number of them go through a surgical treatment unable by itself to cure them. the frequent local recurrence caused by failure of the surgical treatment has been keeping poor survival rates in patients with advanced gastric cancer for decades. The desire of improving survival is the reason of the use of adjuvant therapies. This paper achieved the retrospective study of the influence of preoperative radiation therapy (2000 cGy) in long-term survival rates (120 months) of patients with advanced gastric cancer on stages IIIa, IIIb and IV. The possible injuries caused in the liver and kidney were observed also as well as first group was treated by surgical and radiation therapies and the second received surgical treatment only. There was no statistical difference between the two groups when sex, age, race, occurrence of other diseases, nutritional assessment, TNM stage, occurrence of obstruction or bleeding caused by tumor, surgical procedure and hepatic and renal function were considered. Survival rates and changes on hepatic and renal function were statistically compared. The results showed a statistic improvement on the long-term survival rates of stage IIIa patients treated by preoperative radiation therapy. No statistic difference was observed on hepatic or renal function between the groups. No adverse influence of radiation therapy method was detected by the used parameters. There was no statistical difference between the two groups when immediate surgical complications were considered. (author) 112 refs., 34 tabs.

    The main objective of this thesis is to provide a better comprehension of the phenomena involved in the transport of fission products, from the fuel rod to the coolant of a PWR reactor. To achieve this purpose, several steps were followed. Firstly, it was presented a description of the fuel elements and the main mechanisms of fuel rod failure, indicating the most important nuclides and their transport mechanisms. Secondly, taking both the kinetic and diffusion models for the transport of fission products as a basis, a simple analytical and semi-empirical model was developed. This model was also based on theoretical considerations and measurements of coolant's activity, according to internationally adopted methodologies. Several factors are considered in the modelling procedures: intrinsic factors to the reactor itself, factors which depend on the reactor's operational mode, isotope characteristic factors, and factors which depend on the type of rod failure. The model was applied for different reactor's operational parameters in the presence of failed rods. The main conclusions drawn from the analysis of the model's output are relative to the variation on the coolant's water activity with the fuel burnup, the linear operation power and the primary purification rate and to the different behaviour of iodine and noble gases. The model was saturated from a certain failure size and showed to be unable to distinguish between a single big fail and many small ones. (author)

    Full Text Available OBJETIVO: analisar o desempenho da leitura e escrita em escolares com lateralidade cruzada. MÉTODO: fizeram parte da amostra 166 escolares do terceiro ano do ensino fundamental, com idade entre oito e nove anos. Para avaliação da lateralidade, foi utilizada a escala de desenvolvimento motor -EDM, e para a analise da leitura e escrita foi utilizado o Manual de Desempenho Escolar - MDE. Na análise comparativa do desempenho da leitura e escrita em função da lateralidade (Cruzada, a amostra foi dividida em 2 grupos. Para análise e interpretação dos dados foram utilizados os programas Excel e SPSS for Windows 17.0 e para a análise comparativa entre os dois grupos, o teste "t" para amostras independentes quando os dados se mostraram simétricos, e o teste Mann-Whitney para os dados assimétricos, e para a distribuição dos dados, o teste Shapiro-Wilk. O nível de significância adotado nesse estudo foi p< 0,05. RESULTADOS: verificou- se que de todas as variáveis do desempenho da leitura e da escrita, foram maiores para o grupo das crianças com dominância lateral completa do que para o grupo das crianças com lateralidade cruzada. Na escrita, houve diferença significante entre os dois grupos, sendo atribuído melhor desempenho às crianças com lateralidade destro-completa. CONCLUSÃO: evidencia-se que as crianças com lateralidade cruzada apresentam desempenho inferior na leitura e escrita quando comparadas às crianças com dominância lateral completa. Estes dados justificam a relevância do desenvolvimento psicomotor na infância como fator essencial no processo de aprendizagem escolar.

Abordamo-la como acontecimento, sob o foco da linguística enunciativo-discursiva, envolvendo questões de ordem histórica, política e social. A pertinência da pesquisa parte do fato de que já são aceitos (pelo povo ou pelo Estado sentidos “não criminais” para o termo. Eles não mais condizem com a memória de desprezível, evidenciado sobremaneira no caso “mensalão”, demonstrando a não transparência da língua, a sua plasticidade polissêmica, a sua constituição política, a sua configuração opaca, bem como seu equívoco indissociável do acontecimento. Mobilizamos para esta visualização, o dispositivo teórico da Semântica do Acontecimento, ancilar à Semântica Histórica da Enunciação e à Analise de Discurso francesa. Tal postura determina a articulação entre teoria e corpus por meio do a priori da história. Nosso procedimento evidenciará uma língua erudita que pode designar a palavra “corrupção” a partir de seu funcionamento, que se pauta no rol das leis jurídicas e desvela uma performatividade.

    Full Text Available Vários são os exemplos dos modos pelos quais o noturno é capaz de enriquecer imageticamente a representação artística do mundo. Particularmente na poesia surrealista, a construção de um sistema lateral de referencias, diretamente conectado a uma organização mais larga ao nível discursivo, contribui para a construção de um outro modo de representação do universo relacionado ao signo “noite”. Este artigo tem por intuito a analise de alguns exemplos na poesia de Paul Éluard, um dos mais importantes poetas da literatura francesa, e Murilo Mendes, poeta brasileiro ligado ao movimento modernista. Uma atenção especial voltada à estrutura e às funções assumidas pelos signos ligados ao campo mimético da noite demonstra o modo pelo qual alguns dos mecanismos surrealistas e as experimentações no âmbito linguístico tornam-se capazes de produzir alternativas ao modelo de representação baseado em conveniências e na codificação logica da linguagem literária.

    Today most oil companies would be better described as water companies. Total worldwide oil production averages some 75 million barrels per day and, while estimates vary, this is associated with the production of 300 - 400 million barrels of water per day. These values of approximately 5 - 6 barrels of water for every barrel of oil are quite conservative. In the United States, where many fields are depleted, the ratio of water-to-oil production is closer to 9 to 1. In some areas around the world, fields remain on production when the ratio is as high as 48 to 1. Numerous strategies, both mechanical and chemical, have been employed over the years in attempts to achieve reduction in water production. Simple shut-off techniques, using cement, mechanical plugs and cross-linked gels have been widely used. Exotic materials such as DPR (disproportionate permeability reducers) and or new generation of relative permeability modifiers (RPM) have been applied in radial treatments with varying degrees of success. Most recently 'Conformance Fracturing' operations have increased substantially in mature fields as the synergistic effect obtained by adding a RPM to a fracturing fluid have produced increased oil production with reduced water cut in one step, consequently eliminating the cost of additional water shut off treatment later on. This paper presents laboratory testing and worldwide case histories of applications of various RPM materials, at different permeability and temperatures. The paper also describes technical design and operational methodology that we believe to have a significant impact in the development strategies of many fields worldwide. (author)

    The Sterile Insect Technique is a method of pest control allowed in Integrated Pest Management programs in fruit growing, where sterile insects released compete in mate process against fertile wild ones, generating a gradative population reduction. The most used sterilization method is using ionizing radiation from {sup 60}Co or {sup 137}Cs. For efficient application of SIT, an important item is the sterilizing dose. This must be as lower as possible in order to preserve insect behavior. In this work, it was studied the reproductive potential of fruit fly Ceratitis capitata, tsl VIENNA 8 strain, irradiated with different doses of gamma radiation. This strain has been used in population suppression programs at fruit-growing areas from Northeast of Brazil, through a partnership between CENA and Bio factory MOSCAMED Brazil, intending only sterile male releases. Radiation source used was a {sup 60}Co irradiator, with 17.2 x 1012 Bq. Individualized couples were distributed in a randomized delineament with 10 replicates for each treatment and eggs were collected for fifteen days. With 9 and 10 days old, pupae were irradiated with doses ranging from 30 to 120 Gy. All averages of emerged adult's percentages were higher than 90%. In regards to fecundity, different doses did not affect the number of eggs laid, being the overall mean around 30 eggs/couple/day. Fertility data showed that as radiation dose increases, sterility increases. It was concluded that the dose of 90 Gy can be used in Brazil, since to SIT programs a dose is chosen witch prevents an egg hatch higher than 1%. (author)

    The search for new sources of renewable energy order to minimize environmental impacts has led the scientists to develop new alternatives, such as the use of recycling of frying oils to produce biodiesel. The reuse of these oils has the advantage of obtaining a biofuel with the cost / benefit competitive. However, the conditions of post-consumer oils require treatment prior to its conversion the chemical (transesterification), removing solid particulate contaminants and adjusting its color using the clay of Paraiba. The use of biodiesel as fuel presents a reduction of levels of environmental pollution. This study aimed to characterize clay of Paraiba to be used in the clearing of frying oil. It was observed through the results of the Xray fluorescence (XRF) and infrared spectroscopy by Fourier Transform (FTIR), which the clays tested, have been effective in clearing of frying oils, making them similar to oil 'virgin'.

    This study aimed to realize a survey to identify the associated insects to feed the city Sao Paulo / SP and also to assess the effect of gamma radiation on food ration for domestic animals infested by pests. Samples of 20 stores, 'Pet Shop' in different regions in Sao Paulo / SP were subjected to trials of 1 and 45 days for collection of insects with the aid of plastic tray and screens of different sizes. The species Sitophilus zeamais, Cryptolestes ferrugineus, Lasioderma serricorne and Oryzaephilus sp. showed a higher frequency. In assessing the effects of gamma radiation we used samples of maize, sunflower seeds and mix for rodents infested with adults of the species Sitophilus zeamais, Lasioderma serricorne and Plodia interpunctella, after the period of 7 to 10 days the insects were removed and samples subjected to increasing doses of gamma radiation. The species Sitophilus zeamais and Lasioderma serricorne subjected doses from 0,25 to 1,50 kGy and species Plodia interpunctella doses from 0,10 to 2,0 kGy. After 40 days of irradiation was evaluated the number of insects emerged. The results of bioassays with Sitophilus zeamais and with Lasioderma serricorne demonstrated that doses starting at 0,5 kGy was sufficient to cause mortality of eggs and newly emerged larvae. The results with Plodia interpunctella from the 1,5 kGy, hasn't emerged adult insects, concluding that these doses were sufficient to cause mortality of eggs and larvae. (author)

    The production and consumption of edible mushrooms has been increasing in the last years due to its nutritional composition and sensory quality. The irradiation of mushrooms has been used with the purpose of maintaining the fresh product characteristics during shelf-life. The present study evaluated the effect of different radiation doses on the conservation of mushrooms Pleurotus sajor-caju, through by chemical, physical, microbiological and sensorial parameters. The packaging consisted on polystyrene trays with 250 g of sample, wrapped in polyvinyl chloride (PVC). The mushrooms were irradiated with doses of 125, 250, 500 and 750 Gy in a Gamma cell 220 type irradiator, and stored at 4 +- 1 deg C and 90% UR for 10 days. The proximate composition (moisture, crude fibre, total protein, total fat and ash), total soluble solids, pH, texture, color (L, a, b, Chroma and ho), enzymatic activity (polyphenoloxidase and peroxidase), microbiological (total coliform, Escherichia coli and total psychotropic bacteria) and sensory evaluation (color, taste and appearance) were determined in the 1st, 5th and 10th storage days. For the respiratory rate analysis, 30 g of sample were placed in jars and stored at 4 +- 1 deg C and 90% UR for 8 days. CO{sub 2} was analyzed every day using a gaseous chromatograph. The results were submitted to variance analysis and average test using the SAS statistical package. The total protein and total fat values did not differ significantly between treatments or storage periods, while the moisture, crude fibre and ash values differ between treatments and periods. The dose of 750 Gy darkness the mushroom in the last evaluation, and texture was better in control during the storage period. The color (L, a), texture and proximate composition values did not differ significantly between treatments or storage periods. A significant increase was observed for soluble solids, b{sup *} and enzymatic activity values in all treatments at the end of the storage period. Values of polyphenoloxidase and peroxidase activities increased in the last day of evaluation in samples irradiated with 250 Gy. This fact may be a result of the water radiolysis process, since mushrooms have high water content. The dose of 125 Gy increased the respiratory rate of the samples until the 5th storage day in comparison to the other treatments, causing reduction in the product shelf-life. The samples irradiated with 250, 500 and 750 Gy had a reduction on the respiratory rate if compared with the control, so contributing to the maintenance of the post harvest quality during the storage. The samples which received 750 Gy obtained the best results in the microbiological analyses, with reduction of total coliform and psychotropic bacteria during the storage period. Sensory analyses showed that the control had higher scores for color, aroma and appearance attributes; they were above the acceptability limit until the last storage day. In general, the irradiated samples were accepted for the evaluated attributes until the 5th storage day; thus, establishing the shelf-life for irradiated mushrooms (author)

    The main dosimetric characteristics of the Fricke Xylenol Gel (FXG) solution were established for further application in the measurement of dose distribution of clinical electron fields. The dose-response curves of the FXG in a thermal neutron field were also evaluated for application in Boron Neutron Capture Therapy (BNCT) and industrial electron fields. The standard reading technique was the spectrophotometry. For clinical fields the intra and inter-batch reproducibility of FXG solution are better than 1.4% and 5.1%, respectively. The optical response presents a linear behavior for doses ranging from 0.2 to 40 Gy independently of the electron energy and the dose rate in the studied ranges. Due to the effects of the FXG natural oxidation, the optimum elapsed time between FXG preparation and irradiation was established as 24h. The behavior of the dose-response curve does not change the obtained absorbance values relative to the non-irradiated dosimeter response during the studied period. The dose-response curve to industrial electron beam presented an exponential decreasing behavior. The optical response to thermal neutrons beam presented a linear behavior for the studied dose range. According to the obtained results to the different radiation fields studied it was not observed changes in the wavelength of the typical bands of the absorption spectrum radiation induced. Additional tests were performed with FXG solution to verify the viability and application of FXG dosimetry on intracavitary brachytherapy using digital photographic imaging. The excellent performance of the FXG dosimeter indicates that this dosimeter may be applied to tri-dimensional dose evaluation in radiotherapy treatments using electrons and neutron beams. (author)

The dose-response to the industrial electron beam presented an exponential decreasing behavior and the neutron beam for research in BNCT presented a linear behavior for the complete studied dose range. According to the obtained results for the different types of radiation studied for the FXG, there was no change in the position of the characteristic bands of the absorption spectrum due to the interaction of these radiation types. Additional tests were performed to determine the digital photographic imaging of FXG analyses viability and the application of FXG dosimetry on intracavitary brachytherapy. The good performance of the FXG dosimeter in the tests that were carried out indicates that this dosimeter may be applied to the tri-dimensional dose evaluation in radiotherapic treatments using electrons and neutron beams.

    In this dissertation we use the Laplace transform to derive expressions for nonstandard albedo boundary conditions for one and two non-multiplying regions at the ends of one dimensional domains. In practice, the fuel regions of reactor cores are surrounded by reflector regions that reduce neutron leakage. In order to exclude the reflector regions from the calculations, we introduce a reflection coefficient or albedo. We use the present albedo boundary conditions to solve numerically slab-geometry monoenergetic and multigroup diffusion equations using the conventional finite difference method. Numerical results are generated for fixed source and eigenvalue diffusion problems in slab geometry(author)

    The utilization of fuels of agricultural origin in the cycle diesel engines is a good alternative to reduce dependence on importation petroleum, since these fuels are a renewable source of energy. The utilization of biodiesel as biofuel is a contribution to the environment, reducing the qualitative and quantitative form levels of environmental pollution. The recycling of post-consumption oil helps reduce the uncontrolled disposal and environmentally dangerous, than to obtain fuel with a cost / benefit and offering a competitive alternative commercial advantage. However, these oils should go through a process of decontamination and clearing up the stage of chemical conversion which is used clay to lighten the oil. This work had as its objective to make a literature revision evaluating the potential of the clearing clay modified in Paraiba, used in post-consumption oils for application as biofuel. (author)

    It was designed and developed a geometric acrylic head phantom (GHP) for Quality Assurance (QA) in Stereotactic Radiosurgery (SRS). Inside the phantom there are inserts that are able to accommodate acrylic targets representing the tumor tissue and organ at risk in the region cranial brain, the brain stem. The tumor tissue is represented by two semi-spheres of acrylic with a diameter of 13.0 mm and cavities in the central region for accommodation of a TLD-100 detector and a small radiochromic EBT Gafchromic filmstrip. The brain stem is represented by the two parts of acrylic cylinder with a diameter 18.0 mm, 38.0 mm length and cavities along the central region to accommodate the 5 detectors TLD-100 and yet another of EBT film. The distance tumor - brain stem is 2.0 mm. The experimental setup was filled with water, attached to the stereotactic frame to determine the coordinates of the target and underwent computed tomography (CT). Cf images were transferred to the SRS planning system BrainLab (BrainScan). The contours of the lesion and organ at risk were delineated and, through the technique of multiple circular arcs, the planning was conduced with five arches, one isocenter and a collimator of 17.5 mm from the combination between the table and gantry . The dose delivered to the isocenter of the lesion was 3.0 Gy and the total coverage of tumor volume corresponds to the 75% isodose. This experimental arrangement is subjected to radiosurgery treatment, after which the dosimeters are evaluated and their responses compared with the values of planned doses. The linear accelerator used was a Varian CLlNAC 2300 CID, photon beam of 6 MV, installed at the National Cancer Institute (INCA). For verification of dose distributions in 3D, the films were irradiated in three planes: sagittal, caronal and axial. The .films were scanned and digitized on a scanner Microtek ScanMaker 9800XL model. The dose distributions in irradiated films were compared with the distributions of doses provided by the planning system through the software PTW VeriSoft gamma index method. The results were obtained with TLD agree with planned dose values within the limits of acceptance. For EBT Gafchromics films, in ali treatment plans, there was agreement between the doses values and isodoses, measured planned, within the tolerance limits for SRS (+- 5% of the administered dose in the isocenter of the lesion and {+-} 1,0 mm spatial deviation), showing that the method used is adequate to ensure the quality of the radiosurgery treatment.

    This paper presents a methodology for assessing the reliability indices for composite generation and transmission systems based on Support Vector Machines (SVM). The importance of SVMs is its high generalization ability. The SVMs are used to classify data into two distinct classes. These can be named positive and negative. Thus, the basic idea is to classify the system states into success or failure. For this, a pre-classification of states is achieved by performing the proposed SVM-based neural network, where the sampled states during the beginning of the non-sequential Monte Carlo simulation (MCS) are considered as input data for training and validation sets. By adopting this procedure, a large number of states are classified by a simple evaluation of the network, providing significant reductions in computational costs. The proposed methodology is applied to the IEEE Reliability Test System and to the IEEE Modified Reliability Test System. (author)

    Despite the wide range of antineoplastic agents available, resistance of some types of cancer and toxicity to normal cells have been identified as the main causes of treatment failure and death. The lack of early and precise diagnosis is also responsible for reducing survival of cancer patients. In this context, the development of substances with low toxicity and therapeutic potential and/or diagnosis purpose, is the major tool in an attempt to increase the survival of patients and assure the safety and efficacy of treatment. Thiosemicarbazones (TSC) are a class of synthetic compounds that have several biological activities, including antitumor. Although several studies have shown the great potential of TSC as therapeutic and / or diagnostic agents, different chemical modifications performed on this class of molecules indicate new possibilities for applications and still require further studies. The objective of this study was to evaluate the potential applicability of 2-acetylpyridine N-4-phenyl thiosemicarbazones derivatives for cancer therapy and diagnosis. The results showed that all 13 TSC tested were cytotoxic to breast and glioblastoma tumor cell lines, presenting higher in vitro antitumor activity than etoposide, an antineoplastic and inhibitor of topoisomerase II frequently used for cancer therapy. The TSC that have halogen or nitro on ortho position showed higher antitumor activity in vitro than their isomers with halogen or nitro on meta or para position of the phenyl group. H2Ac4oFPh and H2Ac4oClPh compounds showed the highest antitumor activity among all tested compounds, with IC{sub 50} in nanomolar order. These TSC induced cell death by apoptosis and oxidative stress was responsible, at least in part, for this type of cell death. The 5 mg.kg{sup -1} H2Ac4oFPh dose, administered s.c., for 4 consecutive days, did not induce important toxicity; however, the same treatment protocol was not effective for tumor growth reduction in an animal model of brain tumor. Radioactive probes of H2Ac4oFPh were synthesized using {sup 111}In or {sup 67}Ga as radiotracers, with satisfactory specific activity and radiochemical purity. H2Ac4oFPh-{sup 111}In was more useful than H2Ac4oFPh-{sup 67}Ga, with higher specific activity, better chemical purity, better in vitro stability, higher distribution volume, faster blood clearance and, therefore, was considered the most promising for application in molecular imaging studies. H2Ac4oFPh-{sup 111}In also showed high lipophilicity and was internalized by glioblastoma cells in vitro. H2Ac4oFPh-{sup 111}In showed significative tumor uptake in vivo, however, the high abdominal uptake and high background did not allow a good visualization of tumor in imaging studies. Unlike intravenous administration, intratumoral administration allowed greater diffusion and retention of H2Ac4oFPh-{sup 111}In in the tumor site and significantly reduced the activity accumulated in the organs. These results encourage new experiments to be performed in order to promote the complexation of H2Ac4oFPh with particle emitters, such as yttrium-90, to evaluate its application in local radioisotopic therapy for glioblastoma multiforme.

    The main dosimetric properties of jade and of Brazilian silicates of the jade family were studied for application in radiation dosimetry of high doses. Jade is a common denomination of two different silicates: jadeite, Na Al(Si{sub 2}O{sub 6}), and nephrite, Ca{sub 2}(Mg, Fe){sub 5}(Si{sub 4}O{sub 11}){sub 2} (OH){sub 2}, that belong to the subclasses of the pyroxenes and amphiboles respectively. The jade samples studied in this work were from: Austria, New Zealand, United States and Brazil. The Brazilian silicates of the jade family studied in this work were the amphiboles: tremolite,Ca{sub 2}Mg{sub 5}(Si{sub 4}O{sub 11}){sub 2}(OH){sub 2} e actinolite, Ca{sub 2}Fe{sub 5}(Si{sub 4}O{sub 11}){sub 2}(OH){sub 2}; and the pyroxenes: rhodonite, MnSiO{sub 3} and diopside, Ca Mg(Si{sub 2}O{sub 6}). The mineralogical and chemical composition of these materials were obtained using the neutron activation analysis and X-ray diffraction techniques. The main dosimetric properties (emission curves, calibration curves, reproducibility, lower detection limits, angular and energy dependence, etc) were studied using the thermoluminescent (T L), thermally stimulated exo-emission (TSEE) and electronic paramagnetic resonance (EPR) techniques. The jade-Teflon and the silicate-Teflon samples present two T L peaks around 115 deg C (peak 1) and 210 deg C (peak 2). The calibration curves of the studied materials present a linear behaviour between 0.5 Gy and 1 kGy. The TSEE emission peak occurs at 240 deg C for all samples, and the calibration curves present a sub linear behaviour between 100 Gy and 20 kGy. In the case of the EPR technique, only jade USA has a potential application for radiation dosimetry. A static computational simulation of the most probable intrinsic and extrinsic defects in rhodonite was also realized. Among the basic defects, the Schottky defects of rhodonite are the most probable to occur and, among the extrinsic defects, the divalent and trivalent dopants present the best possibility of inclusion in rhodonite.

    This work describe the enzymatic synthesis of the glucose ester starting from fatty acid, using protease Bacillus subtilis as biologic catalyst. The efficiency of ester has determined through the surface tension analyses in different pH (2-12), temperature (25-100 deg C) and salinity (50-115 g/L of NaCl). For a better understanding as for the applicability of the ester of sugar in drilling fluids, it was done necessary to know the values of interfacial tension of the oil/water; in that analysis, the mineral oil was investigated as oily phase and, as aqueous phase, biosurfactant solution. The results of interfacial tension of the water/oil and biosurfactant /oil they allowed to quantify us the influence of the benefactor's front to an organic phase, because the same made a significant reduction the interfacial tension of 26,0725 mN/m (water/oil) or 1,7527 mN/m (biosurfactant aqueous solution/oil). D-glucose ester was shown stable in different concentrations of NaCl, pH and temperature, and efficient in the reduction of the superficial tension of the water (of 72 mN/m for 28 mN/m). Preliminary test reveal that the ricinoleoil of D-glucose presents functionality as lubricant for drilling fluids to the base water. In the studied formulations, the obtained composition reduces the coefficient of lubricity of 0,20 for 0,04 and it stabilizes the fluid, reducing the volume of the filtrate of 5,0 mL for 3,4 mL.

    The natural decomposition of rubber is a very slow process due to its three-dimensional network formed by vulcanized crosslinked structures becoming extremely difficult to reprocess this material. The present work aims to study the application of gamma irradiation as devulcanization process for material reuse/recycling. The interactions of elastomers with ionizing radiation of a gamma source were investigated and the changes in physicochemical properties of the materials were evaluated. Formulations of NBR (acrylonitrile - butadiene) and EPDM (ethylene - propylene - diene terpolymer) from the rubber industry were crosslinked by conventional sulfur-based mixing. Master - batch was processed with rubber powder (industrial waste) and virgin rubber. The raw material (master batch) was irradiated in {sup 60}Co source at doses of 50, 100, 150 kGy and dose rate of 5 kGy h{sup -1} at room temperature. The irradiated material was incorporated in classical sulfur-based formulations. The formulations were characterized by: infrared spectroscopy (FTIR), thermal analysis (TG and DTG), tensile strength, elongation at break, hardness, abrasion resistance, rheometry and swelling. The results showed a predominance of chain scission at a dose of 50 kGy for EPDM rubber. For nitrile predominance of chain scission was observed at a dose of 100 kGy. These results show the possibility of the use of gamma radiation for the reuse/recycling of EPDM and nitrile rubbers. (author)

    The Human Respiratory Tract Model proposed by the ICRP Publication 66 accounts for the morphology and physiology of the respiratory tract. The characteristics of air drawn into the lungs and exhaled are greatly influenced by the morphology of the respiratory tract, which causes numerous changes in pressure, flow rate, direction and humidity as air moves into and out of the lungs. Concerning the respiratory physiological parameters the breathing characteristics influence the volume, the inhalation rate of air and the portion that enters through the nose and the mouth. These characteristics are important to determine the fractional deposition. The model uses morphological and physiological parameters from the Caucasian man to establish deposition fractions in the respiratory tract regions. It is known that the morphology and physiology are influenced by environmental, occupational and economic conditions. The ICRP recommends, for a reliable evaluation of the regional deposition, the use of parameters from a local population when information is available. The main purpose of this study is to verify the influence in using the morphology and physiology parameters representative of a sample of the Brazilian population on the deposition model of the ICRP Publication 66. The morphological and physiological data were obtained from the literature. The software EXCEL for Windows (version 2000) was used in order to implement the deposition model and also to allow the changes in parameters of interest. Initially, the implemented model was checked using the parameters defined by the ICRP and the results of the fraction deposition in the respiratory tract compartments were compared. Finally, morphological and physiological parameters from Brazilian adult male were applied and the fractional deposition calculated. The results suggest a significant variation in fractional deposition when Brazilian parameters are applied in the model. (author)

    The Er:YAG laser technology has been thoroughly studied, since its invention, and has been increasingly recommended in Dentistry. However, its use in deciduous teeth has not been deserving the equivalent attention to its counterpart in permanent teeth, despite of the deciduous teething occur in a phase of life in which it has a far more importance than its substitutes. For that reason, this study aims to identify the suitable parameters to the clinic procedures in deciduous teeth, using the already established protocols in permanent teeth. The study was lead in a way to resemble the most the conditions of the clinical use of the laser. Five groups were analyzed using different energy densities and repetition rates. Each group was composed of 10 first superior right deciduous molars randomly selected. The energy densities and repetition rates used for each group were: 60 mJ 15 Hz, 250 mJ 2 Hz, 250 mJ 15 Hz, 400 mJ 6 Hz and 500 mJ 2 Hz. The results obtained allowed us to conclude that the use of the Er:YAG laser in Odontopediatrics is effective, safe and secure and the main reason for its recommendation is the low transfer of heat to the adjacent tissues of the applied surfaces.

    Ferritic stainless steels are ferromagnetic materials. This property does not allow their use in orthopedic prosthesis. Nevertheless, in some specific applications, this characteristic is very useful, such as, for fixing dental and facial prostheses by using magnetic attachments. In this study, the corrosion resistance and cytotoxicity of the AISI 444 ferritic stainless steel, with low nickel content, extra-low interstitial levels (C and N) and Ti and Nb stabilizers, were investigated for magnetic dental attachments application. The ISO 5832-1 (ASTM F-139) austenitic stainless steel and a commercial universal keeper for dental attachment (Neo-magnet System) were evaluated for comparison reasons. The first stainless steel is the most used metallic material for prostheses, and the second one, is a ferromagnetic keeper for dental prostheses (NeoM). In vitro cytotoxicity analysis was performed by the red neutral incorporation method. The results showed that the AISI 444 stainless steel is non cytotoxic. The corrosion resistance was studied by anodic polarization methods and electrochemical impedance spectroscopy (EIS), in a saline phosphate buffered solution (PBS) at 37 °C. The electronic properties of the passive film formed on AISI 444 SS were evaluated by the Mott-Schottky approach. All tested materials showed passivity in the PBS medium and the passive oxide film presented a duplex nature. The highest susceptibility to pitting corrosion was associated to the NeoM SS. This steel was also associated to the highest dopant concentration. The comparatively low levels of chromium (nearly 12.5%) and molybdenum (0.3%) of NeoM relatively to the other studied stainless steels are the probable cause of its lower corrosion resistance. The NeoM chemical composition does not match that of the SUS444 standards.

    An activity in engineering projects has been changed over the past two decades with regarding to working practices. Difficulties arising from the increasing complexity of projects, especially in industrial sectors, have taken this activity a constant search for new methods and tools which enable increased speed in performing tasks of daily life of the project. Currently, the development of these tools has been based on a friendlier interface to the end user, minimizing the need for extensive and repetitive training. Moreover, the industry responsible for this development of these kind of tools is still in the search for knowledge in order to explore the plain capabilities within wide projects on solutions offered. This article deals with one of these innovations on the spotlight, besides of being not a technology issue. It's based on the same basic platform available since the creation of models used together with databases. However, this new vision of work inserts one more specialty in the virtual designing of structures to support industrial pipes, as well as other design disciplines, nor taken advantage of these capabilities with regard to the generation of information, its control and management.

    In Brazil and worldwide the nuclear power has occupied a prominent position with many applications in industry, power generation, environment and medicine, improving the quality of tests and treatments, therefore people's lives. Uranium is the main element used in nuclear facilities and it s employed as base material to generation of electricity in the manufacture of radiopharmaceuticals. In the '50s, during the Cold War, the then newly created International Atomic Energy Agency proposed to oversee nuclear facilities and encourage the manufacture of nuclear fuels with low-enriched uranium (LEU) fuel came then type Material Test Reactor (MTR), manufactured initially in U{sub 3}O{sub 8} and U{sub 3}Si{sub 2} later, both dispersed in aluminum. The use of this technology requires a constant improvement of all processes involving the manufacture of MTR subject to several international protocols, which seek to ensure the reliability of the fuel from the standpoint of practical and environmental. In this context, the control of impurities, from the point of view of neutron economy, directly affects the quality of any nuclear fuel, so strict control is necessary. The literature has reported procedures which, beyond generating residues, are lengthy and costly, they need calibration curve and consequently reference materials. The aim of this work is to establish and validate a methodology for nondestructive quantitative chemical analysis, low cost and analysis time, as well as minimize the generation of waste, for multielement determination of major constituents (Utotal and Si) and impurities (B, Mg, Al, Cr, Mn, Fe, Co, Ni, Cu, Zn, Mo, Cd and others) present in U3O8 and U{sub 3}Si{sub 2}, meeting the needs of nuclear reactors in the nuclear fuel qualification type MTR. For that purposes, will be applied the X-ray fluorescence technique which allows fast chemical and nondestructive analysis, aside from sample preparation procedures that do not require previous chemical treatments (dissolving, digesting, and others). To corrections like effects of spectral and matrix were applied and evaluated the fundamental parameter method, univariate calibration curve and multivariate calibration. The results were compared by means of statistical tests in accordance with ISO 17025 in MRCs (123 (1-7) and 124 (1-7)) MCRs of U{sub 3}O{sub 8} from New Brunswick Laboratory (NBL) and 16 U{sub 3}Si{sub 2} samples provided by CC of IPEN/CNEN-SP. The chemometrics is a promising method to determination of minor and major constituents on the U3Si2 and U3O8 basis nuclear fuel, because the precision and accuracy are statistically equal volumetric analysis, gravimetric and ICPOES methods.

    The electrophoretic deposition (EPD) is recognized as the most versatile technique for processing particulate materials, due to low cost, deposition in minutes and forming of pieces with complex geometry shapes. In this work an experimental setup for the simultaneous conformation of 16 ceramic tubes by EPD was built. Bimodal submicron Yttria-stabilized zirconia particles were deposited into graphite electrodes, after suitably adjusting the rheological characteristics of the suspension in isopropanol. After graphite burning and YSZ sintering at 1500 deg C, the ceramic tubes were characterized by X-ray diffraction, scanning probe microscope, impedance spectroscopy and electrical response as a function of oxygen content. Small dense one end-closed ceramic tubes, fully stabilized in the cubic phase, were successfully obtained by the EPD technique, showing the ability of that technique for processing large quantities of tubular solid electrolytes with electrical response to different amounts of oxygen according to the Nernst law (author)

    The main objective of this dissertation is to adapt the methodology of Strategic Environmental Assessment (SEA) to the case of ethanol fuel production in Brazil. The results are be utilized in decision-making processes as well as in the discussion on future tendencies of risks and opportunities regarding the development of ethanol as the principal renewable liquid fuel. Taking into account the international experiences of countries with a tradition in sectoral planning, SEA is found to be the instrument in public environmental management that can most adequately consider the environmental variable - beginning already at the planning stage of the ethanol industry, a necessity that has strongly unfolded itself following the deregulation of the sector in Brazil. The conflicts that may emerge from large ethanol production surpluses for export are also identified through the application of specifically designed indicators. (author)

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

    This study evaluated the risk of internal occupational exposure associated with the incorporation of {sup 131}I via inhalation, in Nuclear Medicine Services, using aerosol analysis techniques. Occupationally Exposed Individuals (IOE) involved in handling this radionuclide are subject to chronic exposure, which can lead to an increase in the committed effective dose. Results obtained in preliminary studies indicate the occurrence of incorporation of {sup 131}I by workers involved in handling solutions for radioiodine therapy procedures. The evaluation was carried out in radiopharmacy lab (nuclear medicine service) of a public hospital located in the city of Rio de Janeiro. After confirmed the presence of the radioisotope, by a qualitative assessment, it was determined an experimental arrangement for sample collection and were detected and quantitated the presence of steam {sup 131}I during routine work. The average concentration of activity obtained in this study was 3 Bq / m{sup 3}. This value is below of Derived Concentration in Air (DCA) of 8.4 x 10{sup 3} Bq of {sup 131}I / m{sup 3} corresponding to a committed effective dose of 1.76 x 10{sup -4} mSv. These results demonstrate that the studied area is safe in terms of internal exposure of workers. However, the presence of {sup 131}I should be periodically reevaluated, since this type of exposure contributes to the increase of the individual effective doses. Based on the data obtained improvements were suggested in the exhaust system and the use of good work practices in order to optimize the exposures.

    The Espirito Santo Basin integrates the group of basins along the eastern Brazilian continental margin. It is located between 18 deg and 21 deg S, encompassing an area of approximately 220,000 km{sup 2}, onshore and offshore the Espirito Santo State. Its geological limit with the Campos Basin to the south is defined by a Precambrian basement high (Vitoria Arch), and its northern limit with the Mucuri Basin is defined by a geopolitical limit. The study of salt tectonics processes in the Espirito Santo Basin allowed the deformational analysis and interpretation of the chronological evolution of the mini-basins developed between salt diapirs. We observe an intrinsic relationship between halokinesis and creation of subsidence troughs that may be important for trapping hydrocarbon reservoirs, and consequently form oil and gas accumulations in this portion of the basin. This geodynamics evolution of these structures is marked by a strong linkage between salt movement and coeval sedimentation in the interdomal basins, forming structures and stratigraphic traps that may constitute important aspects for the petroleum geology.

    A Bayesian approach is adopted to analyze the sequence of seismic events and their magnitudes near Jo\\~ao C\\^amara which occurred mainly from 1983 to 1998 along the Samambaia fault. In this work, we choose a Bayesian model for the process of occurrence times conditional on the observed magnitude values following the same procedure suggested by Stavrakakis and Tselentis (1987). The model parameters are determined on the basis of historical and physical information. We generate posterior samples from the joint posterior distribution of the model parameters by using a variant of the Metropolis-Hastings algorithm. We use the results in a variety of ways, including the construction of pointwise posterior confidence bands for the conditional intensity of the point process as a function of time, as well as, a posterior distribuition as a function of the mean of occurrence per unit time.

    It was planned and executed the implementation of a Central Composite Rotatable Design (CCRD) to the riser of a FCC (Fluid Catalytic Cracking) cold pilot plant, to identify the basic fluid dynamic characteristics of this type of reactor. The Fluid Catalytic Cracking is the major process in oil refineries in the world. It is realized in a vertical cylindrical reactor called riser, with a short contact time between the cracking catalyst and vacuum gas oil vapors. The constant evolution of the FCC process has required the analysis of fluid dynamics using computational fluid dynamics (CFD) software. However, analysis of images produced by the application of CFD to study of risers requires preliminary concepts of the relationship between response variables and independent variables. With the CCRD implementation was performed a total of 12 experiments, being 4 full factorial, 4 axial points and 4 central points. The dependent variables were the velocities of the components (cracking catalyst and compressed air) and the pressure drop in the riser. There was a great contribution of solids flow rate for the solid phase velocity and for the pressure drop. The effects of interaction between the flow rate phases are considerably senses in pressure drop through the riser, however, for the velocities of both phases this interaction becomes negligible.

    The aim of this work is to investigate and apply a method for predicting petrophysical properties from bidimensional petrographic image data. Based on the assumption of statistical homogeneity, the method uses stochastic simulation to reconstruct the porous media tridimensional structure. The geometrical characterization of the simulated media allows the construction of a network model to simulate fluid flow and estimate permeability, formation factor, mercury capillary pressure curves and resistivity index as function of water saturation. This method is applied to four porous systems with different heterogeneity levels. The results demonstrate that good predictions depend on the appropriate image acquisition resolution, which identifies pores and throats that effectively control the flow properties of the system. The capillary pressure curves suggest the necessity of scale composition. The electrical properties are affected by samples porosity, with reliable estimates being restricted to water-wet systems.

    In this work, the in vitro corrosion resistance of the Ti-13Nb-13Zr alloy, manufactured at a national laboratory, and used for orthopedic applications, has been investigated in solutions that simulate the body fluids. The electrolytes used were 0.9 % (mass) NaCl, Hanks' solution, a culture medium (MEM), and the two last electrolytes, without and with addition of hydrogen peroxide. The aim of peroxide addition was to simulate the conditions found when inflammatory reactions occur due to surgical procedures. The corrosion resistance of alloys commercially in use as biomaterials, Ti-6Al-7Nb and Ti-6Al-4V, as well as of the pure titanium (Ti-cp), was also studied for comparison with the Ti-13Nb-13Zr alloy. The corrosion resistance characterization was carried out by electrochemical and surface analysis techniques. The electrochemical tests used were: open circuit potential measurements as a function of tim; potentiodynamic polarization; and electrochemical impedance spectroscopy (EIE). The impedance experimental diagrams were interpreted using equivalent electric circuits that simulate an oxide film with a duplex structure composed of an internal and compact, barrier type layer, and an external porous layer. The results showed that the corrosion resistance is due mainly to the barrier type layer. The titanium alloys and the Ti-cp showed high corrosion resistance in all electrolytes used. The oxides formed on the Ti-13Nb-13Zr, either naturally or during immersion in MEM ar Hank's solution was characterized by X-ray photoelectron spectroscopy (XPS) and scanning electron microscopy (MEV). The results showed that the presence of hydrogen peroxide in MEM promotes the growth of the porous layer and incorporation of mineral ions, besides favouring hydroxyapatite formation. The cytotoxicity of the Ti-13Nb-13Zr alloy was also evaluated and it was shown to be non-toxic. (author)

    Objective: this study focuses on the biochemical response of the following variables: prostate volume, prostate-specific antigen (PSA) value, Gleason scores, staging, the risk of the disease, and hormone therapy. Objective: in the period between February of 1998 and July of 2001, 46 patients with prostate cancer were treated with radiotherapy, in a combination of teletherapy and high-dose rate (HDR) brachytherapy. The age ranged from 51 to 79 years (averaging 66.4 years). T1c stage was the most frequent one: 30 (65%). The Gleason score was below 7 in 78% of the patients. PSA ranged from 3.4 to 33.3, being below 10 in 39% of the cases. The average prostatic volume was 32.3 cc. Twenty-eight percent of the patients received hormone therapy. Teletherapy dose ranged from 45 to 50.4 Gy, associated to four fractions of 4 Gy of HDR brachytherapy. Results: the follow-up period varied from 6 to 43 months. Four patients missed the follow-up and four died (one due to the disease). Out of the 39 patients that were analyzed, 76% presented a less than 1.5 PSA. None of the analyzed variables were found to be of statistical significance (p > 0.05) regarding biochemical control. Conclusion: the use of HDR brachytherapy was found to be effective in the treatment of prostate cancer and, in this study, the variables considered as prognostic factors did not interfere in the biochemical control.

    The world's concern regarding the reduction atmospheric emissions, due to the global warming, it is a subject that is being quite discussed. A parameter that evaluates the environmental impact considering the emissions of CO{sub 2}, SO{sub x}, NO{sub x} and PM in an integral way and comparing to the international air quality standards that are in force is called ecological efficiency ({epsilon}). This paper intends to compare environmental impacts of the atmospheric pollution due to technologies that use the biomass as fuel with conventional and advanced technologies of electricity generation. It is also evaluated the advantages of the use of the cogeneration starting from the biomass. The most important results that were obtained are comparative graphs confirming that the use of the biomass as energy source is a good option from the ecological point of view, when pollution control methods are used.

    Lithostratigraphic studies of Ponta Grossa Formation (Devonian - Parana Basin) suggest the recognition of three members, denominated: Jaguariaiva Member, Tibagi Member and Sao Domingos Member. This work studies the formation as a whole, but predominantly the Tibagi Member, the most controversial, regarding its stratigraphic genesis. Differing from the other members, that are predominantly pelitic, the Tibagi Member has a sandy composition with the facies; distal storm, proximal storm, deltaic outlet bars and littoral drift currents. The disposition of these facies, formed in marine transitional environment, reveals deposition with a pro gradational array, beginning in shallow platformal environment, with strong storm influence, and covered by deltaic outlet bar deposits. Finally, the coastal drift currents process prevailed. Based on the facies analysis and the comparison between gamma-ray profiles of outcrops and geophysical profiles of wells, the formation was divided in two depositional sequences. In the upper sequence, where it is suggested that Tibagi Member sandstones represent deposits formed in a tract similar to a shelf edge systems tract. This system tract was used (elaborated for passive margin basins, and not for ramp type basins, as the Parana Basin), to have the possibility of obtaining good explanations to understand the deltaic progradation associated with the deposition of that interval, clarifying issues referring to the relative sea level behavior, to the sedimentary contribution, and to the stratigraphic pile up. Finally, comparisons were made with existing stratigraphic models, with the aim to establish a discussion on this important subject in order to promote new debate on the Ponta Grossa Formation stratigraphic sequences.

    This paper analyses the economical-financial viability of a hypothetic aeolian project at the Itaparica, Bahia, Brazil. Brazil presents a great aeolian potential, particularly at the Northeastern region, where various aeolian enterprises had been implanted due to favorable conditions of the wind in that region. However, for the increasing the aeolian generation it is necessary that studies have to be done concerning to the technical viability and, specially the economical-financial viability, because the investors need reliable subsides for the decision making.

    The recent moves towards the insertion of biofuels in the energy matrix of a number of countries are opening new prospects for agricultural production and for agroindustrial chains. This study aims at understanding the mechanisms taking place within a production system geared towards biodiesel production. The emergence of this new productive base raises new research issues: in what circumstances are the structuring, organization and implementation of these biodiesel productive chains taking place in Brazil? What are the effects of biodiesel production on local economies? Hence, the central objective of this study is the development and validation of an analytical structure capable of characterizing the biodiesel productive arrangements and identifying their economic and social impacts at the regions where they are installed. A preliminary analysis identified that a biodiesel productive arrangement is emerging in the State of Piaui, Northeastern Brazil, Our theoretical basis comprises elements from the regional economy, biorefineries, local production arrangements and innovation. For the analyses, we employed the methods of input-output, local quotient and shift-share. It can be said that a new social-economic dynamics is taking place in Piaui; however, the company needs to assess its interaction with local institutions as well as its castor bean production strategies.

    The importance of the refining segment in the oil productive chain turns decision making on production and investment to be made at refineries dependent upon general context of the oil industry. Several technical and economic factors limit the possibilities to be foreseen by the managers. The ultimate goal of a refinery is to meet market demand in a region. Moreover, the type of processed oil and refining techniques will shape the profile of the production of derivatives. In a segment dynamic and full of uncertainties, such as refining, where the type of oil supplied to processing, specifications of products, and their demands, changes in the course of time, how to keep refining margins acceptable? This paper presents the relationship between the characteristics and the use of different kinds of oil, the characteristics of the national market of derivatives, and some characteristics of the refining processes considered in the study. The possible economic impacts that the introduction of different processes can bring to a refinery are analysed and alternatives for expansion are evaluated. To achieve these goals, a methodology for analysis considering the yield of Marlin oil refining for different schemes has been developed. (author)

    Air pollution has been a frequent topic of research, due to the effects that it can cause on the health of living organisms, environment and climate. In order to identify pollution sources and their effects, biomonitoring has been studied due to its low cost and possibility of sampling in wide geographic areas. In this study for passive biomonitoring of air pollution levels at the Cidade Universitaria Armando Salles de Oliveira (CUASO), University of Sao Paulo campus, epiphytic lichens of Canoparmelia texana species were used. The lichens collected from tree barks at different sampling sites in the CUASO were cleaned, freeze-dried and ground for analyses. Lichen samples were analyzed by X - ray fluorescence spectrometry (XRFS) and neutron activation analysis (NAA). For XRFS, cylindrical pellets of samples were prepared to determine As, Br, Ca, Cl, Cr, Cu, Fe, K, Mn, Rb, S, Sr and Zn. For NAA, lichen sample aliquots along with synthetic elemental standards were irradiated both for short and long periods at the IEA-R1 nuclear research reactor. The induced activities were measured by a gamma ray spectrometer to determine As, Br, Ca Cd, Cl, Co, Cr, Cs, Cu, Fe, K, La, Mg, Mn, Rb, Sb, Sc, Se, U, V and Zn. The precision and accuracy of the results were evaluated by the analysis of certified reference materials (MRCs). Their results of relative errors and standard deviations were below 15% for most of the elements. The standardized difference or En score values were lower than |1| indicating satisfactory results. Replicate analyses of a lichen sample by XRFS and NAA, indicated good homogeneity of the sample for the elements determined. The lichen results showed that the mean concentrations of As, Br, Ca, Cd, Co, Cr, Cs, Rb, Sb, Se and U were higher in samples from CUASO than those from regions considered unpolluted. For Fe, K, La, S, V and Zn, they were of the same order of magnitude. The correlation study between the elements showed high correlation (r > 0.7) for elements originated from the natural and anthropogenic sources. The principal component analysis (PCA) applied to the results showed six major components, where components 1 and 2 accounted for 52.9 % of the variance of the data. Enrichment factors (EF) calculated for the results of lichens from CUASO and a region considered unpolluted were EF> 1 for most elements, showing that these elements may be from anthropogenic sources. From the results obtained in this study can be concluded that the elements found in lichens from CUASO can be originated from sources such as resuspension of soil particles and anthropogenic emissions.

    The energy is the fuel of growth and an essential requirement for the socioeconomic development. However, the current production model is based on fossil fuels, considered as threat to man and nature. As for, the relating to the human activities and their effects on the environment, they are handled by the implementation of a more rigid model of environmental control and the mobilization of the society in favor of technologies with less energy impact. In view of this scenario, the Proton Exchange Membrane Fuel Cell - PEMFC has been recognized as a key for the vital need of a clean and efficient energy. Considering the conventional power generation system, their advantages during usage configure its application as an ideal option for several utilities, especially in the mobile sector. Even though, the focus on several environmental evaluations in energy systems is referred back to the initial stage of it use, the employment relating to production of the system and to final destination should be considered, since these also present impacts. In the case of PEMFC, their previous and subsequent phases of use are issues related to the platinum catalysts, which indicates an environmental importance that cannot be overlooked. In this sense, the Life Cycle Assessment has been used to understand and to question the risks and opportunities that are associated to certain product, starting from a systemic concept of their relationships with the environment. It is precisely in this context that the present research intends to present its major contribution, starting from an exploratory study towards the its objectives to provide an environmental analysis of such technology linked to post stage of powder-use of the membrane electrode assembly - MEA, concerning the platinum catalysts, on the subject of Life Cycle Assessment - LCA. To attain such aim, the relationships between energy, environment and development are presented and discussed, as well as, the Fuel Cell technology and the current studies on LCA of PEMFC. Several questions raised up on this issues have contributed in the development of a method of recuperating the PEMFC catalysts and, particularly, for its subsequent environmental evaluation. Among significant results are the importance of LCA, out lined as useful tool for perceiving the weight of environmental matters concerning the platinum and its subsidy strategies relating to the development, consolidation and to the innovation of PEMFC.

    In this work the use of natural gas as fuel in a tri generation system proposed for a bovine slaughterhouse is analyzed. Traditionally, great part of the slaughterhouses uses firewood, and eventually oil, as fuel to supply the thermal energy and purchases electric energy from a concessionaire. The configuration proposed will allow the simultaneous generation of electricity, vapor for the processes and refrigeration to the slaughterhouse consumption, as well as generation of electricity surplus for commercialization. For evaluation of the plants performances, energetic and exegetic analyses are carried out for the plant expanded by conventional mode and by means of the tri generation system. Finally, thermo economical analyses, for evaluation of reflexes of the costs of capital investment and of fuel on the composition of products costs, are accomplished for each case considered.

    Various studies demonstrate that different frog species produce distinct classes of biologically active peptides. These peptides can act as alternative agents against pathogenic bacteria and fungi by membrane permeability. Although studies have recently demonstrated that this process is utterly related to the secondary structure adopted by the peptide (in this case, the {alpha}-helical structure) when in contact with the bacterial membrane, the detailed mechanism is still unknown. In this work we describe a conformational analysis of distinctin, a heterodimeric peptide isolated from the skin of Phyllomedusa distincta, an anuran found in the Brazilian Atlantic Forest. The study yielded a stable geometry with a high content of the {alpha}-helical structure both in chains 1 and 2 of distinctin, showing strong interaction between them. (author)

    This work has as objective to promote the analysis of the radiological doses and quality of the image of the technical letter used for the accomplishment of thorax and coxal radiographic examination of animals of canine and feline species. The study was accomplished in the service of Diagnosis for Image in Veterinarian Hospital of Veterinary Medicine and Zootecnia College of University of Sao Paulo, in two conventional equipment. Initially, physical features of the animals and the technique used were collected for each one of the 188 radiographic examinations of thorax and 52 examinations of coxal. The animals were placed in different groups, according to their body weight. For each group, the averages for each feature were calculated: thickness of the radiographed region, tension, electric current, time of exhibition, current product electric-time, size of the used film, presence or absence of bucky and feature of focus (narrow or thick). On the basis of the averages of group M (of lesser weights that 5kg for cats and between 10,1kg and 20kg for dogs), was executed a physical analysis of the current technical letter, using the equipment: ionization chamber (to determinate the value of kerma in air), simulator objects (representative of the thickness of the animal) and three dispositive standards of test that evaluate space resolution, resolution in low contrast and contrast-detail. The obtained images were analyzed and compared for a physicist and a radiologist medical veterinary. The results had shown that the examinations supply dose considered high for techniques used mainly for coxal. The equipment A, although to supply higher doses, presents the better images for the majority of the projections. However, the study indicates that there are not exactly reference levels, but these examinations must pass for improvement of quality of image (author)

    South America combines economic and population growth with a consequent rapid increase in electricity demand. This can only be covered by building new power plants, use of the remaining renewable potential and expansion of transmission lines. The expansion of supply in all regions, with reliable generation and transmission systems is the greatest challenge for the continent in order to reduce social differences and not to curb economic development. To support the energy planning the application of system models represents useful method. This paper intends to analyze the expansion effect of power plant parks in regard of greenhouse gases emissions using a regionalized model system 'TIMES (The Integrated Markal - EFOM System)'. The model includes 10 South American countries (Argentina, Brazil, Bolivia, Chile, Colombia, Ecuador, Paraguay, Peru, Uruguay and Venezuela) with their respective power parks and transmission lines, demand divided in sectors, potential use of renewable energy sources, gas pipelines and possibilities of new interconnections within and between countries. As results are obtained the future installed capacity and generation according the energy use, greenhouse gases emissions, as well as the investments needed to expand the electric system in different scenarios.

    Although the Brazilian gas market has been showing steady growth and positive news regarding new discoveries, it is not immune to be questioned about its capacity of value generation, and, in particular, if the new companies, operating in distribution have generated it. Value creation, and its management, has become one of the main activities of the modern corporation in order to align the management and shareholders interests. Despite its advancements, the Brazilian NG industry can be considered at its early stages when compared to those of other countries whose industry is more traditional and mature. The process of unbundling of the gas industry, as well as of the public utilities, has become one of the icons of the Brazilian government policies since the mid 90's. Taking into account regulatory change which had only allowed in the last couple of decades the participation of private ownership into the domestic gas market, a follow up of these companies' performances is of interest. Following the concept of value generation, the present study examines the Brazilian gas distribution sector. Based on a detailed analysis of the financial statements of some of the main companies in the sector, that together represent around 68% of the total Brazilian market, this paper verifies whether the gas distribution sector have presented a positive or negative EVA{sup R}, in other words, if, during the period from 2002 to 2007, these newly companies in the gas industry have created or destroyed value in Brazil.

    This paper analyzes both the carbon fiber-based development for uranium centrifuges and the research project that supports its development effort over time. The carbon fibre-based engineering properties make it a valuable supply for high technological products, such as uranium ultracentrifuge. There is no production of such fibers in Brazil. Its trade is subject to international market restrictions due to carbon fibers' dual applications. The Centro Tecnologico da Marinha em Sao Paulo (CTMSP), the Universidade de Campinas (UNICAMP), the Universidade de Sao Paulo (USP), the RADICIFIBRAS Company, and the Financiadora de Estudos e Projetos (FINEP), which is responsible for the project financial support, established a partnership aiming the development of a domestic polyacrylonitrile (Pan)-based carbon fiber industry. Such alliances or technological partnerships are best known in developed countries, such as USA and Japan, as Cooperative Research or Research Joint Ventures (RJV). (author)

MÉTODOS: Estudo transversal, de base populacional, conduzido de janeiro/2006 a junho/2007, na região metropolitana de São Paulo, como parte do estudo internacional (Gender, Alcohol, and Culture: an International Study. Os sujeitos (1.501, sendo 609 homens e 892 mulheres eram residentes da região metropolitana de São Paulo, tinham 30 anos ou mais de idade e foram selecionados aleatoriamente, a partir de amostragem complexa por conglomerados. Todos os indivíduos consentiram em participar da pesquisa. A variável dependente foi risco cardíaco avaliado através do WHO Rose Angina Questionnaire. A análise multivariada consistiu em regressão logística, tendo sido realizado ajuste para uso de tabaco e índice de massa corpórea. RESULTADOS: A taxa de resposta foi 75%. Ser mulher, ter mais idade, ser negro, fumante e ter um índice de massa corpórea elevado, foram associados a maior risco para doença coronariana. Indivíduos que nunca beberam na vida (OR = 2,22 e ex-bebedores (OR = 2,42 tiveram maior risco de doença cardíaca do que aqueles que informaram beber até 19 g de álcool por dia, sem episódios de beber excessivo. Entre os que tiveram episódios de embriaguês observou-se uma tendência a maior risco (OR = 3,95, p = 0,09. CONCLUSÕES: Nossos achados sugerem um menor risco para doença coronariana entre os bebedores moderados. Destaca-se que os estudos que avaliam o impacto do álcool sobre doença cardíaca precisam identificar o padrão de uso de álcool dos sujeitos, visto que este aspecto pode modificar o risco. Políticas públicas são necessárias para reduzir o uso nocivo de álcool e a morbidade a ele relacionada no país.

    Full Text Available O presente trabalho trata-se de uma investigação sobre manifestações políticas de extremismo de direita na América do Sul contemporânea, em específico, a atuação da organização skinhead internacional denominada Blood and Honour. Privilegiasse, nessa analise, o debate da categoria nacional-socialismo através de fundamentos da Ciência Política a das Relações Internacionais.No entanto nem todo skinhead é uma apoiador do nazismo, assim como nem todo entusiasta da suástica é um skinhead; existem grupos que se autodenominam enquanto skinheads que apoiam e militam em prol de uma organização social racialista baseada em uma suposta supremacia branca, esses ficaram conhecidos como skinheads White Power.Através dessa pesquisa buscou-se estudar o pensamento e atuação política disseminada e empreendida pela Blood and Honour, apontando, mais especificamente, para sua articulação na América do Sul. Foram analisadas as características constitutivas do pensamento nacional socialista difundido pela organização principalmente através de sites na internet, buscando-se compreender como o nacional socialismo foi, enquanto categoria analítica, modificado para melhor servir os objetivos da Blood and Honour, com enfoque maior nas concepções de internacionalização do movimento.Observou-se que a internacionalização presente no pensamento nacional socialista da Blood and Honour, está pautada em uma organização racial supra estatal baseada na união de indivíduos ou grupo de indivíduos supostamente herdeiros de uma ancestralidade ariana; diferentemente da concepção nacional socialista alemã das décadas de 1920 e 1930 que buscava uma internacionalização através da expansão do domínio nazista, sendo essa altamente pautada na ação estatal e em uma concepção de nacionalidade cívica.

No escopo deste artigo, no diálogo com os refereciais teórico-metodológicos da sociologia da infância, foram analisadas três das entrevistas realizadas, de forma a destacar a singularidade dos processos socializatórios vividos por tais sujeitos, definidos por duas categorias identitárias: geração e inserção em movimentos sociais. Verifica-se que as crianças, em sua ação coletiva voltada para a atividade do brincar, buscavam interpretar sua experiência coletiva, lançando mão de elementos da cultura infantil, de forma a elaborar o vivido. Ao mesmo tempo, buscavam estabelecer relações com outros universos sociais, tais como a escola, de maneira a construir novos espaços de sociabilidade.This papper describes an etnographical research realized with a group of childs from the Movimento dos Sem Terra of Minas Gerais/Brazil. Using metodologies strategies like participative observation and interviews, we focused the signification of childhood experience inside an organized social movement. According to that, in dialogue with the teorical references of Childhood Sociology, the research analises their identity construction process, considering two central categories: generation and insertion in social movements. The children, in coletive action centered on playing, uses it to interpret their social universe, elaborating their own experience. In other hand, they tried to construct new relations with another social universes, like school, in order to increase their sociabilities.

    Ao longo das três últimas décadas, o projecto da epistemologia passou por um processo de crítica e de transformação, marcado, sucessivamente, pela transferência da soberania epistémica para o “social”, pela redescoberta da ontologia e pela atenção à normatividade constitutiva e às implicações políticas do conhecimento, chegando mesmo a ser postulado o abandono da epistemologia como projecto filosófico. Em contraponto a esse processo, foi ganhando contornos a proposta de uma outra epistemologi...

    Biodiversity studies allow ecosystem assessment and monitoring of environmental changes and impacts. Parasite diversity could reflect the host/ parasite coevolutionary process and the environment changes that permit the loss, gain or maintenance of species. This survey used species/morphotypes of helminths eggs found in feces from seven wild mammal species (the groups Dasypodidae and Large Cats, and Tamandua tetradactyla, Cebus apella, Alouatta caraya, Cerdocyon thous, Pecari tajacu) and from two domestic species (Canis familiaris and Sus scrofa), which occur within the Serra da Capivara National Park (PNSC) and surrounding areas in order to analise the diversity of mammal intestinal helminths. This work used the helminthological fauna findings of wild and domestic mammals, to consider a possible helminth flux between these two host groups using Unweighted Pair Group Method with Arithmetic Mean (UPGMA) of the hosts based on helminthological fauna composition. The results indicate that the region of the PNSC still maintains environmental conditions that still keep wild mammal helminthological fauna composition different from the one found for domestic mammals.

    The dissertation aims to offer a current vision on the use of electrical energy inside CEEE's newly defined area of operation. It also intends to propose different alternatives to set up a Demand Side Management (DSM) project to be carried out on the same market segment, through a Residential Load Management program. Starting from studies developed by DNAEE (the Brazilian federal government's agency for electrical energy), to establish the load curve characteristics, as well as from a research on electrical equipment ownership and electricity consumption habits, along with the contribution supplied by other utilities, especially in the US, an evaluation is offered, concerning several approaches to residential energy management, setting up conditions that simulate the residential segment's scenarios and their influence on the general system's load.

    The aim of this study is to determine the effects of diode laser irradiation on enamel demineralization. To achieve this goal appropriate photon absorbing substances for the laser radiation, safe laser parameters and adequate temperature measuring apparatus had to be determined. Next, the effects of diode laser and acidulated phosphate fluoride on enamel demineralization by calcium content analysis were evaluated with inductively coupled plasma atomic emission spectrometry (ICP-AES). In the first part of the study, five dyes consisting of vegetable coal diluted in five different liquids were analyzed and vegetable coal diluted in physiological solution was chosen for use as absorber. Methodologies to measure pulp chamber temperature were evaluated and modeling clay was chosen as fixture for the enamel samples held at body temperature. In the second part of the study, different energy density parameters (1.8 J/cm{sup 2}, 3.7 J/cm{sup 2}, 5.6 J/cm{sup 2}, 7.4 J/cm{sup 2} and 9.3 J/cm{sup 2}) exposure times (10, 15, 20, 25 e 30 seconds) and time intervals between dye application and laser irradiation (5, 30, 60, 90 e 120 seconds) were evaluated with respect to temperature changes in the pulp chamber. The enamel morphology was analyzed by scanning electron microscopy. Acid resistance was measured using seventy five enamel specimens, divided in five groups (control, fluoride, laser, laser + fluoride and fluoride + laser). The amount of calcium lost during demineralization in lactic acid was measured by ICP-AES. The results obtained in this experiment permit the conclusion that diode laser irradiation did not increase acid resistance. When associated with fluoride, the acid resistance did not differ from the results obtained with fluoride alone. (author)

    Full Text Available In characterising rhetoric, its persuasive intent should be highlighted because the persuasive element is true of all three rhetorical genera. Graeco-Roman pupils were well-trained in the rhetorical arts and it can be accepted that Paul also had a working knowledge of rhetoric. Rhetorical analysis of the New Testament attempts to study the texts of the New Testament in the light of rhetorical features, as developed by the classical theorists and refined by a modern scholar like Perelman. Since the 1970's rhetorical analysis of the New Testament has flourished, although approaches have varied considerably and not all efforts were convincing. Nevertheless, it has become clear that the rhetorical approach can enrich our understanding of the New Testament, and especially of its letters, considerably. Examples from Romans and Galatians are presented to underscore this point. Since preaching, like rhetoric, aims at convincing and persuading an audience, rhetoric can provide us with important stimuli for the praxis of preaching, as can be demonstrated from the five prescribed phases of preparing a public speech, as well as from the three modes of persuasion: logos, ethos and pathos.

    Solar heaters are an appropriate technology for tropical and sub tropical to warm bath water through the energy in sunlight. The development of conventional solar heaters is in the market and its acceptance is still low due to high cost. However, low-cost solar heaters have been developed in recent years to meet a consumer demand that currently do not have access to this technology, especially low-income rural communities. The aim of this study was to analyze the economic feasibility of solar water heaters built with recyclable materials (plastic bottles and milk cartons) through the consequent reduction of sales of electricity. For development work, a heater was built with recyclable materials in accordance with the manuals provided by the Department of the Environment of Parana (SEMA) and found time to use electric showers by families of rural properties in order to determine the costs and billing of electricity. By spending on materials, we concluded that the system was feasible, with amortization over 13 months in fixed installments of R$ 23.79. (author)

    The impacts to wildlife in areas where gas pipelines will be implemented are considerable, changing the existing balance. The main environmental measure adopted in the cases is the deployment of the Fauna Management Programme. This programme is sub - divided into two: Monitoring and Rescue of the fauna. The tracking step starts before the installation of the venture, with the completion of a first in order to identify the impacts before the venture, and finishes two years after the end of the works. These studies are based on guidelines set in the Normative Instruction of the environmental licensor agency, in which the criteria for implementation are restrictive, often without making a license agency distinction of methodology for enterprises with different characteristics. This article intended to review the criteria and the procedures established by the legislation and its real applicability in gas pipeline projects face to the environmental impacts identified to this activity. For this analysis, the methodology used was the case study of two gas pipelines: Cabiunas - Vitoria (GASCAV) and Cacimbas - Catu (GASCAC). The results allowed to conclude that the actions developed to the Sub-Programme of Rescue of the fauna are satisfactory to control environmental impacts and that the Sub-Programme of Monitoring of the fauna just confirm behaviors and information's previous detected.

    The use of water cut as a parameter for determining the shut-in point of production wells is very frequent. However, in most cases, the value of this parameter that is used in the process is not optimized, which can lead to suboptimal performance, as shown in this work. An additional way to improve the water management strategy of the field is set by controlling the injection rate by determining the optimal shut-in point of an injection well, which should be closed when its interaction with the producing wells is negative for their financial performance. To know the interaction between the injector and the producer wells becomes important in order to determine the most appropriate time for the closure of the injector wells. The objective of this study is to illustrate a methodology that allows the optimization of the development and water management strategy of oil fields by using the shut-in control of injection wells, in addition to managing production wells, using numerical reservoir simulation. For this study three case studies are proposed: (1) simulation of a homogeneous and isotropic reservoir model, with the purpose of determining the injection shut-in point by the water cut value obtained from the economic scenario, (2) simulation of the process in simplified cases of heterogeneous reservoirs and (3) application of the methodology to a case of more complex reservoir geology and well configuration in different economic scenarios. The results show that for reservoirs with expected production of large volumes of water and flow high injection rates, the isolated use of water cut for producing wells control as the only procedure to manage the flow of water within the reservoir may be insufficient. Moreover, depending on the price scenario used in economic forecasting and considering cases with heterogeneities, the determination of the shut-in point of injection and producing wells individually can be the most appropriate option for the development and water management strategy of the field.

    Nowadays, the energy deficit represents one of the biggest governmental challenges, since there is still a great number of communities living in areas without electricity energy; and thus without access to electro-electronic equipment such as television, refrigerators, computers. The main focus of this work is to present the possibility of electricity energy generation in conjunction with the frozen or hot water production in for places without electricity transmission nets or even any type of alternative power plants. The system is based on the standard air cycle called Brayton cycle composed of a turbo-compressor model 4LGZ from BorgWarner, a combustion chamber, a power turbine, a heat exchanger, a water-ammonia chiller, a 5.0 kV A generator, and a command panel for automation and distribution of energy. This system that uses natural gas or LPG, will supply electric energy from the generator, hot water from the heat exchange with the gases of combustion, and water frozen from chiller using as the hot source the gases proceeding from the power system. The prototype is already being tested and the first results obtained are excellent. In this paper, we analyze the internal combustion chamber temperatures. (author)

    The Brazilian cement industry produced 64 million tons of cement in 2012, with noteworthy contribution of CP-II (slag), CP-III (blast furnace) and CP-IV (pozzolanic) cements. The industrial pole comprises about 80 factories that utilize raw materials of different origins and chemical compositions that require enhanced analytical technologies to optimize production in order to gain space in the growing consumer market in Brazil. This paper assesses the sensitivity of mineralogical analysis by X-ray diffraction associated with cluster analysis to distinguish different kinds of cements with different additions. This technique can be applied, for example, in the prospection of different types of limestone (calcitic, dolomitic and siliceous) as well as in the qualification of different clinkers. The cluster analysis does not require any specific knowledge of the mineralogical composition of the diffractograms to be clustered; rather, it is based on their similarity. The materials tested for addition have different origins: fly ashes from different power stations from South Brazil and slag from different steel plants in the Southeast. Cement with different additions of limestone and white Portland cement were also used. The Rietveld method of qualitative and quantitative analysis was used for measuring the results generated by the cluster analysis technique. (author)

    To choose among the variety of oleaginous plants for biodiesel production, the oil content of several matrices was determined through different low-field {sup 1}H nuclear magnetic resonance (NMR) experiments with varied pulse sequences, namely single-pulse, spin-echo, CPMG, and CWFP. The experiments that involved the first three sequences showed high correlation with each other and with the solvent extraction method. The quality of the vegetable oils was also evaluated on the basis of the existing correlation between the T{sub 2} values of the oils and their properties, such as viscosity, iodine index, and cetane index. These analyses were performed using HCA and PCA chemometric tools. The results were sufficiently significant to allow separation of the oleaginous matrices according to their quality. Thus, the low-field {sup 1}H NMR technique was confirmed as an important tool to aid in the selection of oleaginous matrices for biodiesel production. (author)

    Today, oil companies must be able to survive in a hostile and competitive environment. Such environment involves volatility of oil prices, the narrow margins of profitability, and ever increasing environmental restrictions. In order to survive, firms must have the appropriate tools to consider the tradeoffs involving the financial, environmental, technological and of market parameters which are the key elements within the investment decision-making process. The aim of the present work is to analyze the behavior of the weights (relative importance) of the attributes int the multi-criteria decision model through a high dimension sensitivity analysis. Among the benefits of such method are: provide the analyst (decision-maker) with a better characterization and control of the weights of the attributes, providing the user with a clear view of the entire decision process. The methodology suggested in this dissertation was applied in two oil exploration and production case studies. The first case involved the selection of an exploratory target among three options. In this case, there is interaction of the objectives of the company, where financial, technological and of market parameters interact. In the second case, a hypothetical production project is suggested. For this second study, the decision-maker has the option of using one of the following production systems: a FPSO (Floating, Production, Storage and Offloading); a TLP (Tension Leg Platform); or a SS (Semi Submersible). The attributes for each one of the production systems are financial, technological and environmental. In this second case, the model makes it possible to simulate several options, providing the manager with the choice of the most appropriate production system to this objectives and preferences.

    The Pien area presents the major geotectonic domains separated by the Pien Shear Zone (PSZ). The northern one is the Rio Pien Granite-Mylonitic Suite composed by calc-alkaline granitoids of Neoproterozoic age. The southern domain is represented by the Amphibolite-Granulite where high grade metamorphism took place at the end of paleoproterozoic time. Considering the identified lithotypes, their geochemical affinity (particularly the Ti, Cr, Ni and REE content) and the geological context observed in the area, a geotectonical model of active continental margin related to subduction SSZ (Supra-Subduction Zone) is proposed. K-Ar on plagioclase from gabbronorites gave Neoproterozoic ages although Sm-Nd whole rock isochron yielded Paleoproterozoic ages. Based in geochemical data, it is proposed that the biotite gneiss and biotite-amphibole-gneiss which occur near the PSZ have a shoshonitic to high-K calc-alkaline features which are characteristic of active continental margins. K-Ar on biotite extracted from these rocks, gave Neoproterozoic ages. The available radiometric data for the Rio Pien mylonitic granitoids show that between 650-595 Ma the generation, deformation and cooling below the isotherm of 250 deg C occurred. On the other hand, the geochronological data for the Agudos do Sul Massif are in the 590-570 Ma interval showing its younger generation. The Sr{sup 87} / Sr{sup 86} initial ratios for both granitoids suggest more involvement of the continental crust in the origins of Agudos do Sul granitic Massif. The analyses of the entire set of the available data for the Pien area allows the suggestion of a geotectonic scenery related to the evolution of an active continental margin during the collages associated to the Brasiliano Cycle 201 refs., 130 figs., 6 tabs., 2 maps

    When a safety system is under aging the failure times follow non-exponential distributions, and its interstate transition rates become time-dependent. It follows, therefore, that the stochastic process employed in the modeling becomes Nonmarkovian. In this thesis, this analysis is developed using an alternative method, called the device of stages which allows the transformation of Nonmarkovian models into equivalent Markovian ones. That transformation consists in reshaping the state transition diagram with time-dependent transition rates into a new one where fictitious states (called stages) are added and whose transition rates are constant. The number of added stages and their connections are identification parameters of the device of stages used for the equivalent Markovian model and requires a robust and efficient optimization tool. In order to perform a global search in such a topologically complex space, a genetic algorithm has been developed to automatically determine the stages combination and set of parameters which better represent the analyzed distribution. The developed genetic algorithm has demonstrated a good ability for optimizing the method of stages. Results concerning the application to a nuclear reactor protection system are shown and commented, in which the Weibull distribution is employed for modelling failure times. (author)

    Ionizing radiation from gamma radiation sources or X-ray generators is frequently used in Medical Science, such as radiodiagnostic exams, radiotherapy, and sterilization of haloenxerts. Ionizing radiation is capable of breaking polypeptidic chains and causing the release of free radicals by radiolysis.of water. It interacts also with organic material at the molecular level, and it may change its mechanical properties. In the specific case of bone tissue, studies report that ionizing radiation induces changes in collagen molecules and reduces the density of intermolecular crosslinks. The aim of this study was to verify the changes promoted by different doses of ionizing radiation in bone tissue using Fourier Transform Infrared Spectroscopy (FTIR) and dynamic mechanical analysis (DMA). Samples of bovine bone were irradiated using Cobalt-60 with five different doses: 0.01 kGy, 0.1 kGy, 1 kGy, 15 kGy and 75 kGy. To study the effects of ionizing irradiation on the chemical structure of the bone, the sub-bands of amide I, the crystallinity index and relation of organic and inorganic materials, were studied. The mechanical changes were evaluated using the elastic modulus and the damping value. To verify whether the chemical changes and the mechanical characteristics of the bone were correlated, the relation between the analysis made with spectroscopic data and the mechanical analysis data was studied. It was possible to evaluate the effects of different doses of ionizing radiation in bone tissue. With ATR-FTIR spectroscopy, it was possible to observe changes in the organic components and in the hydroxyapatite crystals organization. Changes were also observed in the elastic modulus and in the damping value. High correlation with statistical significance was observed among (amide III + collagen)/{sub v1,v3}, PO{sub 4}{sup 3-} and the delta tangent, and among 1/FHWM and the elastic modulus. (author)

    The EVA is a copolymer used by Brazilian shoes industries. This material is cut for the manufacture of insoles. This operation generates about 18% of waste. The EVA waste can be reused in incorporation in Portland cement to construction without structural purposes. The aim of this work is to show X-rays images to assessment the space distribution of the wastes in the cement and to evaluate the use of this methodology. Cylindrical specimens were produced according to ABNT - NBR 5738 standards. The volume relation of sand and cement was 3:1, 10% and 30% of waste was incorporated in cement specimens. X-Rays images were obtained of cylindrical specimens in front projection. The images showed that the distribution of the waste is homogeneous, consistent with what was intended in this type of incorporation, which can provide uniformity in test results of compressive strength.

    The tungsten carbide (WC) has wide application due to its properties like high melting point, high hardness, wear resistance, oxidation resistance and good electrical conductivity. The microstructural characteristics of the starting powders influences the final properties of the carbide. In this context, the use of nanoparticle powders is an efficient way to improve the final properties of the WC. The high energy milling stands out from other processes to obtain nanometric powders due to constant microstructural changes caused by this process. Therefore, the objective is to undertake an analysis of microstructural characteristics on the crystallite size and microdeformations of the crystal lattice using the technique of X-ray diffraction (XRD) using the Rietveld refinement. The results show an efficiency of the milling process to reduce the crystallite size, leading to a significant deformation in the crystal lattice of WC from 5h milling. (author)

    The internal lining in gas pipelines aims the reduction of roughness and, consequently, the friction factor, therefore resulting in a reduction of pressure drop in natural gas flowing. During Bolivia-Brazil gas pipeline basic design, the cost benefit of internal coating was analyzed, in terms of friction factor reduction and distances between Compressor Stations. It was observed an increase of transport capacity and reduction of compressors' power, thus leading to its utilization. Since the pipeline is already in operation, using a SCADA system with Advanced Functions, a comparison between the current real friction factor in the pipeline with that theoretical values used during the design phase becomes possible. Through this comparison, it is possible to evaluate internal coating's efficiency, quantifying its real benefit for gas pipelines. (author)

    The increasing expansion of compounding pharmacy associated with several reports on variances in the quality of compounded drugs demonstrates the need for verification of quality, safety and efficacy of these products. In this work, physical and chemical analyzes were performed to evaluate the quality of some capsules manipulated enalapril and simvastatin, acquired in five pharmacies in Belo Horizonte /Brazil. Among the analyzes are pharmacopoeial tests for appearance, identification, determination of weight, content, related compounds and uniformity of dosage units, and was also performed neutron activation analysis for the determination of inorganic impurities in drugs sampled. The results showed that 60% of the samples were unsatisfactory for pharmacopoeial tests. The contents of the capsules sampled for individual testing unit dose uniformity between 0% and 136.2%. This test is important in evaluating the quality, which influences the safety and efficacy of drug treatment, since it allows you to check if the product contains the proper dosage and necessary for successful pharmacotherapy. On the other hand, underdosing can lead to reduced or absent desired therapeutic response, and overdoses can provide an undesirable effects and even toxic. The concentration of inorganic impurities was considered to be relatively small. However, no specific limits for some chemical elements in medicine hamper a better thread. In addition, further studies must be performed to assess chronic exposure to low concentrations of inorganic impurities, since drugs can be continuously used, and other sources of exposure must also be considered in order to evaluate the risk. The problems related to the quality and safety of compounded drugs are still reality in the country and reveal a serious public health problem, especially regarding the lack of uniformity between the unit doses of medications. It is suggested that the competent authorities to sanitary products, propose changes in supervision and improvements in legislation, since the analysis required by the law, are not sufficient to ensure the quality of drugs dispensed in pharmacies.

    It is known that the distribution at time intervals of random and unrelated events leads to the Poisson distribution . This work aims to study the distribution in time intervals of events resulting from radioactive decay of atoms present in the UNICAMP where activities involving the use of ionizing radiation are performed environments . The proposal is that the distribution surveys at intervals of these events in different locations of the university are carried out through the use of a Geiger-Mueller tube . In a next step , the evaluation of distributions obtained by using non- parametric statistics (Chi- square and Kolmogorov Smirnoff) will be taken . For analyzes involving correlations we intend to use the ANOVA (Analysis of Variance) statistical tool . Measured in six different places within the Campinas , with the use of Geiger- Muller its count mode and a time window of 20 seconds was performed . Through statistical tools chi- square and Kolmogorov Smirnoff tests, using the EXCEL program , it was observed that the distributions actually refer to a Poisson distribution. Finally, the next step is to perform analyzes involving correlations using the statistical tool ANOVA.

    This paper aims to analyze the potential of palm-oil biodiesel production and consumption in remote Amazonian systems (not connected to the national grid), taking into account economic, social and environmental impacts of this biofuel alternative. Through a detailed analysis of remote systems and in particular the examination of the national subside called 'Combustible Consumption Account', the study presents potential scenarios of biodiesel demand for electricity generation in the region, considering also the generation and grid connections projects in forthcoming years. Definition of current and future quantities of biodiesel needed to maintain thermal production in this system defines the Biodiesel investment necessities in remote Amazonian states (Acre, Amapa, Amazonas, Para, Rondonia, Roraima). Possibility of using biodiesel made progress with the launch of the National Program of Production and Use of Biodiesel (PNPB) in 2004. Although African Palm-oil trees adapt very well Amazonian soil, wide adoption of this specie as raw material for biodiesel production shows some barriers, like raise of palm oil price in global market, palm tree long maturation time and attractive price for conventional diesel in the region. Even if using palmoil biodiesel result in obvious significant social and environmental benefits, these benefits tend not to compensate the inefficiency of the market and, thus, expand the biofuel production in the Northern Region.

    Fibrolipomatous hamartoma of nerve and macrodystrophia lipomatosa are rare conditions that present characteristic imaging findings. The plain films, magnetic resonance imaging studies and medical records of four patients were reviewed. The lesion was resected in one patient allowing histological confirmation of the diagnosis. Diagnosis was based on imaging and clinical findings in three patients who had unavailable biopsy data. We describe two cases of isolated macrodystrophia lipomatosa, one case of fibrolipomatous hamartoma and one case where both conditions were found. In the macrodystrophia lipomatosa cases plain films demonstrated enlargement of osseous and soft tissue structures in the affected limbs, with fatty streaks interspersed along the muscle fibers. The median nerve was affected in the cases of fibrolipomatous hamartoma. Magnetic resonance imaging findings included nerve fascicle thickening characterized by low signal on both T1 and T2-weighted sequences, and surrounding fat, which appears as high signal on T1 and low signal on T2-weighted sequences with fat saturation. Both nerves had a coaxial cable appearance on axial images. The fibrolipomatous hamartoma extended to the nerve branches, which is a typical finding. The typical imaging findings of macrodystrophia lipomatosa and fibrolipomatous hamartoma of nerve, particularly at magnetic resonance imaging examination, allowed a reliable diagnosis of these frequently coexistent conditions.

    Assuming the systems planning radiotherapy recognize all body structures of the same density (d=1 g/cm³), variations in electron density within the irradiated area, as is the case of patients who undergo reconstruction mammary processes and use tissue expanders, may influence the dose distribution in the treatment and may produce heterogeneities which are not measured by changing its actual distribution into healthy tissues or in the target volume to be irradiated. Through the calculation of the algorithms' dose distribution of the XiO® planning system (Fast Fourier Transform, Convolution, Superposition, Fast Superposition e Clarkson), when using correction of heterogeneity between tissues of different densities, there was obtained a percentage ratio of dose increase in the structures of interest, and of the amount of absorbed dose by healthy organs adjacent to the target volume.

    The climate agreement that will take place from 2013 onwards needs to address some of the concerns that were not considered in the Kyoto Protocol. Such concerns include the absence of emission targets for big emitters developing countries and the impacts of unequal carbon-policies on the competitiveness of Annex 1 energy-intensive sectors. Sectoral approaches for energy-intensive sectors can be a solution to both concerns, mainly if they address climate change issues involving all the countries in which these sectors have a significant participation. A sector is a good candidate to the sectoral approaches if it has some characteristics. Such characteristics are high impact to the competitiveness of Annex 1 enterprises derived of the lack of compromises of enterprises located in non Annex 1 countries, high level of opportunities to mitigate GHG emissions based on the application of sectoral approaches and easy sectoral approaches implementation in the sector. Then, this work assesses the petroleum refining sector fitness to the sectoral approaches to address climate change. Also, this dissertation compares the petroleum refining sector characteristics to the characteristics of well suited sectors to the sectoral approaches. (author)

    This study involved an investigation of the failure of a heat exchanger used in the ozone destruction stage of a wood pulp bleaching process at a pulp plant. The following procedures were carried out to determine the causes of the failure: a chemical analysis of the component, atomic absorption spectroscopy, measurements of hardness and of corrosion-related mass loss, characterization by scanning electron microscopy, and chemical microanalysis by X-ray energy dispersive spectroscopy. The corrosion damage of the heat exchanger was caused by chloric and sulfuric acid, which led to pitting, grooving and cracking, as well as generalized corrosion of the component (AISI 316L steel). Nitric acid caused minimal damage to the heat exchanger, with minor generalized corrosion and occasional pitting. White crystals rich in sulfur and chlorine were identified as the corrosive agents acting inside the heat exchanger. (author)

    Brazil is the world's greater producer of charcoal and most of this production takes care of to the siderurgical sector. Thus, one understands that the Brazilian steel is produced of sustainable form. However, such sustainability is not based only on a renewable energy source. The origin of the wood for the carbonization, if proceeding from planted forests or native bushes, is crucial factor in this analysis. Beyond the ambient dimension, the sustainability of the charcoal segment also is influenced by its social, economic and technological aspects. In this context, the present article searches, through the construction and the analysis of the diagnosis of the charcoal in Brazil, to evaluate the sustainability of the sector and to consider alternatives to reach it. The current model of production of charcoal in the country is unsustainable. The main adopted systems of carbonization in Brazil are low level technological with consequent decrease production. The activity is unhealthy, beyond having many cases of enslaved and infantile work. The coal of native forests is much cheaper and the fiscalization is poor, fact that discourages its production from planted forests. But if the vegetal coal will be understood as an energy solution for the siderurgical sector measures can be taken to search a model of sustainable production. (author)

    The present work analyses some proposals of cogeneration systems for the simultaneous generation of power, heat and refrigeration in a brewery. The requirements of steam, refrigeration and electricity, as well as the production of beer in a plant of the Antarctica Company, located in Jaguariuna - SP were collected monthly for the year of 1997. Three conceptions of systems using two gas turbines with heat recovery steam generator were then proposed to meet the surveyed demand. The proposals differ in the refrigeration system: the first one uses a traditional ammonia compression system while the second uses an ammonia absorption system, the third proposal is a combination of the compression and absorption systems. These proposals are compared to the present configuration which purchases electricity from the Public Utility for power and refrigeration (using an ammonia compression)system, and fuel oil to generate steam for process heat. The technical, economical and environmental feasibility of the proposals, as well as of the present configuration are discussed on the basis of mass balances, energy balances (first law of Thermodynamics), exergy fluxes (second law analysis), operational and capital cost, based on simulation of the performance of each configuration proposed to meet the monthly electricity, steam and refrigeration requirements for the referred plant. The turbines were chosen so as to meet the peek energy demand of the plant and two cases were simulated for each proposal: turbine operational meets only the demand of the plant and turbine operates at full load, selling electricity for the Public utility. Results obtained show that the current operational costs are higher than any of the proposals presented. The high capital costs of the proposals, though,make them less interesting financially. The simulation of the case of excess electricity to the Public Utility is very attractive, considering the cost of natural gas 3,38 U$/M btu and the fare of 40 U$/MWh. The proposal of best performance energetically, operationally and economically is the one that uses the combined compression and absorption system, presenting a flexibility to absorb the variations of the electrical and thermal energy demand inherent to the process of production of beer. In general terms, the combination of energy, exergy, economic and environmental analysis are important tools to evaluate concurrent industrial energy technologies. (author)

    Among the implemented measures to control environmental impacts during the crossings of water courses, can be mentioned: the laying of pipe under provisional passages, the execution of physical barriers, the provisional and definitive drainage systems, the riverbank water bodies revegetation after the completion of works and the monitoring of water quality in the previous phases and after the execution of works for the implementation of the crossing. This study examined the effectiveness of these measures using as a case study the works of gas pipelines: Cacimbas (ES) - Vitoria (ES) and Cabiunas (RJ) - Vitoria (ES). In general it was observed that the measures taken were effective. In the case of implemented crossings with the conventional method of monitoring, the results confirmed an expected temporary increase in turbidity, resulting from the removal of sediment of the river bed in order to open the ditch. This impact was shown to be well tolerated by the body water, after crossing back to normal conditions. Regarding the Monitoring of Water Quality, which usually increases the cost of the venture, this was not an effective instrument for the control of impacts due to the time needed to obtain the results of samples taken compared to the time of execution of the crossing.

    The maintenance costs, the operational problems and the failures possibilities of the boron injection system, composed by pumps, valves, heated lines and the boron injection tank, make this tank removal or the boron concentration reduction advisable for Angra 1 Power Plant. The main accident from chapter XV of the final safety analysis report affected by this modification is the main steam line break. It is necessary the interaction of the areas of Accidents and Transients Analysis (RETRAN 02/Mod 5.1 code), Neutronics (APA System) and Thermohydraulics (COBRA IIIC/MIT) to analyse this accident. The present Angra 1 boron concentration is 20000 ppm and it could be reduced to 2000 ppm as a result of the present study. The Departure from Nucleate Boiling Ratio (DNBR) is the restrictive parameter of this accident, which is calculated from the initials and boundary conditions obtained from the Transients and Accidents Analysis and Neutronics areas.

    Proceedings and techniques in order to maximize the reliability and the availability of industrial plants have been used along the last decades by specialists and professionals of maintenance. However, the modem industrial systems' sizing, and the increasing complexity and interdependence among its components have become this activity's planning a more and more difficult task. Considering this scenario, the objective of the present work is to provide a computational tool which is able to help about the taking decision's task, and about planning policies of maintenance practiced in thermonuclear plants. The tool developed is based on the artificial neural networks (ANN) for the recognition of standards and establishment of correlations among events occurred in the components of pressurized water reactor (PWR) typical systems. The ANN work as miners of database of failure events, and are able to identify connections and to establish imperceptible inferences even for the most experienced specialists in maintenance of nuclear systems. The results were attained from realistic data and are confronted against the maintenance's classic policies which are practiced nowadays on PWR thermonuclear plants. These results show the solidity of the technique in valuing and predicting failures in a real power plant, and is able to be used as a tool for supporting decisions about planning maintenance policies on a typical PWR.

    The aim of this study was to analyze the frequency of unstable chromosomal aberrations induced by gamma radiation from a {sup 60}Co source at two different doses. Samples were obtained from a healthy donor and exposed to {sup 60}Co source (Gammacel 220 ) located in the Department of Nuclear Energy of Pernambuco Federal University (DEN/UFPe/Brazil) with a rate of air Kerma to 3,277 Gy/h. Exposures resulted in absorbed dose 0.51 Gy and 0.77 Gy. Mitotic metaphases were obtained by culturing lymphocytes for chromosome analysis and the slides were stained with 5% Giemsa. Among the unstable chromosomal aberrations the dicentric chromosomes, ring chromosomes and acentric fragments were analyzed. To calculate the significance level the chi - square test was used, considering relevant differences between the frequencies when the value of p < 0.05. To calculate the significance level of the chi - square test was used, considering relevant differences between the frequencies when the value of p < 0.05. The results showed that there was significant difference of the frequencies of dicentric chromosomes (from 0.18 to 0.51 to 0.37 Gy to 0.77 Gy), however there was no statistically significant difference between the frequencies of acentric fragments ( 0.054 to 0, 51 Gy to 0.063 to 0.77 Gy) and ring chromosomes (0.001 to 0.51 Gy to 0.003 to 0.77 Gy). The low number of rings is found justified, considering that in irradiated human lymphocytes, its appearance is rare relative to dicentrics. The results confirm that dicentrics are the most reliable biomarkers in estimating dose after exposure to gamma radiation. These two points will make the calibration curve dose-response being built for Biological Dosimetry Laboratory of CRCN-NE/CNEN.

    Objective: In the pediatric group, the radiological diagnosis of bone tumors of the hip is difficult and presents some peculiarities, but reviewed literature does not approach this specific problem. The objective of the present study was to investigate the existence of reliable radiological patterns for the differential diagnosis of these tumors. Materials And Methods: Radiological findings of bone tumors of the hip in ten patients in the age range between 8 and 19 years have been reviewed. Results: Bone reaction (sclerosis or lysis), periosteal reaction (lamellar with single or multiple layers, or radial), tumor extent in the bone and level of soft tissues invasion have presented low specificity. Soft tissue calcifications, when considered as a whole, were non-specific. However, when those calcifications with varied shapes and sizes, nearby the affected bone (pattern I) were separated from those, thin and amorphous, away from the bone (pattern II), we have observed that the pattern I was totally non-specific, and the pattern II was found in the three cases of osteosarcoma (100%) and in only one case of Ewing's sarcoma (16.6%). Conclusion: In the present study, pattern II calcifications have shown a 100% sensitivity and 90% specificity for osteosarcoma. However, their importance may be not limited to the radiological diagnosis. Pattern II calcifications indicate probably ideal sites for biopsy. (author)

    Because of the high cost of electricity connection to distant places, far away from conventional nets, photovoltaic solar energy is widely used in public illumination, water pumping, medical care centers, etc. With the purpose to contribute to a better utilization in this type of energy, the object of the project is to analyze the water flow, power and electrical current of a motor pump to be used for water lift, driven by photovoltaic panels, the data will be collected at every 2 meters in height from 2.2 to 18.2 meters. The analyses show the outflow linear dependence in relation to the height of the water lift, a second order dependence of the electrical power provided by the photovoltaic panels in relation to the solar irradiance on the panels and a linear dependence of the electrical current in relation to the solar irradiance. This study is a part of a project developed at the 'Universidade Tecnologica Federal do Parana' (UTFPR) - Campus Medianeira - PR. Two photovoltaic panels were used from Solarex Brand, model MSX 56, a motor pump made by Shurflo Ltd, model 2088-732, two pyranometers from KIPP and ZONEN CM3, a type K thermocouple, a pressure transducer model HUBA-510 and a water flow transducer.

    Fumagina is produced by the Capnodium fungi, a mushroom from Dothideales order, that lives associated with the yellow aphid (Monelliopsis pecanis), excreting a heavy load of a sugared substance that provides the sooty fungus development, covering, in some cases the totality, of leaves, fruits and branches surfaces. One of the big problems caused by this disease is the physic photosynthesis stuckness, reducing in 98% the active photosynthesis radiation and in 70% the net photosynthesis. This photosynthesis reduction affects the plants carbohydrate reservoirs, resulting in reduced and bad qualified crops. It was employed the Energy Dispersion X-Ray Fluorescence Technique (EDXRF) to study the fumagina disease. The measurements were realized with infected and healthy leaves of citric plants (orange and lemon trees), collected at the Farm School of the State University of Londrina, and also leaves of icsora plant from Piracicaba-SP. Through this technique it was observed a metabolic disorder related to Fe and Ca elements. By comparing the EDXRF spectra of the healthy plant leaves with the infected ones, it was verified that the concentration of Ca is higher than the concentration Fe in leaves of healthy plants, while for the leaves of plants infected with fumagina, it was observed a higher concentration of Fe. Employing EDXRF and the emission/transmission method for the matrix effect correction, samples of the citric plants were also analysed in pellet. The elements K, Ca, Ti, Mn , Fe, Cu and Zn were quantified. It was verified a higher Fe concentration in fumagina samples compared to the samples without fumagina. For all the elements of interest the minimum level of detection found was at the order of {mu}g g{sup -1}. (author)

    Rheology of emulsion mixtures and void fraction measurements of multiphase flows requires proper instrumentation. Sometimes it is not possible to install this instrumentation inside the pipe or view the flow. Ultrasound technology has characteristics compatible with the requirements of the oil industry. It can assist the production of heavy oil. This study provides important information for an analysis of the feasibility of developing non-intrusive equipment. These probes can be used for measurement of multiphase void fraction and detect the flow pattern using ultrasound. Experiments using simulated upward air-water vertical two-phase flow show that there is a correlation between the acoustic attenuation and the concentration of the gas phase. Experimental data were obtained through the prototype developed for ultrasonic data acquisition. This information was processed and used as input parameters for a neural network classifier. Void fractions ({proportional_to}) were analyzed between 0% - 16%, in increments of 1%. The maximum error of the neural network for the classification of the flow pattern was 6%. (author)

Entre todos os processos que podem ser aplicados na obtenção do óleo, a extração usando fluido supercrítico (EFS pode ser um método seletivo e eficiente, dependendo das condições operacionais, como temperatura e pressão, que precisam ser otimizadas. O objetivo deste estudo foi comparar a eficiência da extração supercrítica, utilizando planejamento experimental, na extração do óleo de manjericão com os métodos convencionais (hidrodestilação e soxhlet. Para a realização da parte experimental, foi utilizado dióxido de carbono como solvente para a EFS e hexano, para aplicação no soxhlet. Foi realizado um delineamento central composto rotacional (DCCR, aplicando três pressões (100, 200 e 300 bar e três temperaturas (30, 40 e 50ºC. Através da hidrodestilação, obteve-se o menor rendimento (0,26%, usando o Soxhlet, o rendimento foi de 2,39% sendo superior, comparado á EFS, que foi de 0,43%. O DCCR mostrou que, para otimizar o processo, é necessário aumentar a pressão e a temperatura para o alcance de maiores rendimentos. Foi possível constatar que o modelo matemático representou bem o processo de extração, propiciando o "scale-up" deste.

    Perovskite-type ceramic oxides or their derivatives are used for applications in high technology because of their enormous range of physic-chemical properties with little change in structural characteristics. In this paper we report manufacture ceramic components of a new ceramic Ca{sub 2}AlWO{sub 5,5} by thermo-mechanical process. Stoichiometric amounts of chemical constituents with high degree of purity, were homogenized using a ball mill and high purity alumina balls, compacted by uniaxial pressing and annealed at 1200 deg C for 48 hours. The structural characterization studied by x-ray diffraction that this material has a typical complex ordered cubic perovskite structure. For the study the stability of these ceramics in crude petroleum circular discs of 20 mm diameter and 2 mm thickness were produced and sintering. These discs were submerged in crude petroleum for 15, 30 and 45 days and were examined at each stage by X-ray diffraction, optical microscopy and hardness testing and these results show that Ca{sub 2}AlWO{sub 5,5} are stable in crude petroleum environment.

    This aim of this work is to evaluate the fracture toughness of pipe lines under high internal pressure, used in the petroliferous industry for transportation of gas and oil. These ducts are produced from high strength low alloy steels, classified as API X60. Therefore, to simulate the stress and strain fields ahead of crack, the SE(T) specimens has been point out as the best specimen geometry. The linear load normalization technique, LLN, has been showed as a promissory technique for obtaining the J-R resistance curves. The J values were obtained following the ASTM 1820 and 1152 standards, with the coefficients modified for this specimen geometry. Side groves were executed to avoid crack tunneling and to maintaining the crack on the plane perpendicular to the loading direction. The J-R curves obtained are compatible for high ductility steels. However, the observed J values seems to high, and the factors affecting this result are discussed in this work. (author)

    The aim of this work is to develop a DL-Alanine, Fe-II based gel dosimeter to be applied in the dosimetry of the Co-60 gamma-radiation fields in the dose range of radiation therapy procedures. The aminoacid DL-Alanine is dissolved in an acid solution containing the Fe-II and added to the gel. A series of essays was performed with different chemicals and different procedures were made to evaluate the behavior of the obtained dosimetric gel as function of the time. The absorption spectra, before and after the irradiation, present maximum in 457 nm and 588 nm, respectively. These two peaks correspond to absorption wavelengths of the chemical species Fe-II and Fe-III, respectively, both species being in equilibrium. With the irradiation, the formation of the radicals that oxide the Fe-II into Fe-III occurs, altering the chemical balance of both species - hence the increase of the Fe-III - and causing the gel to change its tonality, in such a way that it is possible to determine the absorbed dose. In the analysis of the spectra and respective dose-response curves it was observed that the dosimetric gel shows linearity in dose range of 0.5 to 40 Gy. From the obtained linearity results, stability and lower detectable dose - 0,3 Gy - it is possible to conclude that the present DL-Alanine, Fe-II based dosimetric gel presents an excellent potential to the application to which it is proposed, namely, the determination of the dose fields in radiation therapy and its future application as a standard in the determination of these fields, in 3D, using the Magnetic Resonance Imaging.

    This work presents here a study on the porosity of cores from Resende Basin (Rio de Janeiro). The first step involved the selection, thinning of the material (core) and sample preparation for the use of porosimeter to obtain effective porosity. The material studied is sandstone, friable, coarse to very fine of three wells (GPR1, GPR2 and GPR3). The fuzzy logic (MatLab) was applied to the effective porosity data calculated from the gamma ray (GR) profile for the construction of a synthetic profile and from this we could identify the errors made in calculating the data. Then the results of porosity from the core were correlated with data from the corrected effective porosity (gamma ray profile) in order to prove the results obtained with both methods. The analysis of the synthetic porosity calculated by the fuzzy logic has shown that this is a promising method for assessing the quality of data and to obtain good fits. (author)

    This in vitro study has evaluated the structural changes on the root dentine irradiated by a CO{sub 2} laser associated or not to calcium hydroxide application, from the irradiated surface analysis by means of Scanning Electronic Microscopy (SEM). The purpose of this evaluation has been the study of an alternative method for the treatment of dentine hypersensitivity. Fourteen human teeth were utilized, third molars, divided into 7 groups. Group I (control group) to which no treatment was applied; Groups II, III and IV were given an application of Ca (OH){sub 2} paste followed by C0{sub 2} laser irradiation, lasting 5 seconds each with intervals of 10 seconds between each application, with continuous emission, power of 0.5 W (Group II), 1.0 W (Group III), and 1.5 W (Group IV); Groups V, VI, and VII were given laser irradiations without the Ca (OH){sub 2} paste following the same parameters applied to groups II, III, and IV respectively. Morphologic changes suggesting to fusion and re-solidification have been observed, as well as the presence of material obstructing the whole analyzed surface on groups II, III, and IV (laser + Ca (OH){sub 2}). As for groups V, VI, and VII, it has been observed fusion, re-solidification, and cracks, and these results being statistically significant when compared the '(Ca (OH){sub 2})' groups to the laser groups. No statistically significant differences were observed regarding the different powers applied in the groups that used the same treatment. Despite this result, it can be stated that powers above 1.0 W (DP = 125,38 W/cm{sup 2}) are unfavorable due to the undesirable morphologic alterations and aesthetic compromising. (author)

    Detailed stratigraphic analysis of the Early Permian Rio Bonito and Palermo Formations of the Parana Basin in the region of Sao Gabriel County has been used for a study on reservoir characterization of paralic sandstones. Two main depositional systems were recognized, a fluvial-dominated delta system and a wave-dominated barrier island system. The succession is divided in two third-order depositional sequences, enclosing thirteen fourth-order para sequences. This high-resolution stratigraphic framework was the base for a multi scale approach on reservoir characterization of the sandstone bodies. Reservoir heterogeneities are discussed, staring from the scale of depositional sequence (heterogeneity level 1), passing down to heterogeneity at the scale of systems tracts (heterogeneity level 2) and finalizing with an approach at para sequence scale (heterogeneity level 3). Main control on heterogeneity at the first level is base-level variation as generating mechanism for un conformities at the sediment type and rate. At the second level, the reservoir heterogeneity is controlled by the lateral and vertical variations in thickness of particular systems within the different systems tracts, and at the third level, the heterogeneity occurs controlling reservoir continuity and connectivities between reservoirs. The study supplies a model which is useful as a predictive tool for similar geologic settings in producing oil fields. (author)

    With the objectives of using a single system of injection and of extending the range of application for the method ASTM D4629/02 'Total Nitrogen in Petroleum Derivatives by the System of Injection with a Syringe and Detection by Chemo- Luminescence', it was studied a procedure by statistical validation with the objective of guaranteeing the analytical reliability of the assay and allowing the inclusion of samples of petroleum and heavy derivatives in one single methodology. The determination of total nitrogen for petroleum and derivatives is traditionally assayed using the method of Kjeldahl - a time-consuming methodology that requires a large amount of time for giving the final result, at the same time that is not recommended for concentrations below 0.1%w/w, which does not meet the requirements for the specifications of the product, in the petroleum industry. An alternative for the method of Kjeldahl is the pyro-chemo luminescence, which allows the achievement of more repetitive results for total nitrogen. In the detection of nitrogen, the technique combines the reliability of oxidative combustion with the sensitivity of chemiluminescence. Therefore, it was developed a protocol of validation in the methodology ASTM D4629/02 for the validation of the extension of the range of application and for the evaluation of the performance of the equipment in analytical conditions, according to the calibration curve.

    Full Text Available This research evaluated, using the in situ technique, the dry matter and fiber fraction degradability of the Mineirão stylo (Stylozanthes guianensis. The nylon bag method was used for the degradability assay, with two incubations in rumen-cannulated adult female cows. In each incubation, 25 samples of 7.0 g each were used. The samples were collected at 0, 6, 9, 12, 24, 36, 48, 72 and 96 hours. The experiment was conducted according to a randomized blocks design and data were submitted to analysis of variance. The maximum effective degradability was obtained in the 2% passage rate. For the 5% passage rate the Mineirão stylo showed effective degradation of 75.70% for dry matter, 59.01% for neutral detergent fiber and 76.81% for acid detergent fiber. The digestibility achieved by the dry matter and fibrous fraction from Mineirão was considered high. These results, coupled with the low lag time found reveal the forage potential of the cultivar.Neste trabalho avaliou-se, por meio da técnica in situ, a degradabilidade da matéria seca e da fração fibrosa da leguminosa estilosantes Mineirão (Stylozanthes guianensis, leguminosa nativa do Cerrado brasileiro.

A microcistina, um heptapeptídeo monocíclico, é produzida principalmente pela cianobactéria Microcistis aeruginosa. São caracterizadas por alguns aminoácidos variáveis, dois deles com uma estrutura não usual que possuem importante papel na hepatotoxidade da microcistina. Apesar do acometimento humano atribuído as microcistinas incluírem gastroenterite, reações alérgicas ou irritativas, neurotoxicidade, o principal alvo da toxina é o fígado. Nos hepatócitos as microcistinas são carreadas pelo sistema transportador do ácido biliar, inibindo a atividade da proteína fosfatase no citoplasma. A inibição leva a mudanças morfológicas na membrana plasmática pela hiperfosforilação de citoqueratinas, e à atividade de promoção tumoral pelas proteínas hiperfosforiladas. Os métodos de detecção e quantificação de microcistinas no ambiente incluem a cromatografia líquida, o bioensaio em camundongos e os testes imunoenzimáticos. O último vem ganhando destaque pela praticidade e alta sensibilidade.

O enraizamento bioantropológico e as características socioculturais comportam graus diversos de experiências, conhecimentos e sabedoria, em uma complexa organização em que as oposições não devem significar extinção e as diferenças não podem traduzir enfraquecimento ou superioridade. Dessa forma, podemos aplicar o conceito do "anel tetralógico" de Edgar Morin, que comporta desordem, organização, ordem e interação para a compreensão dos impasses entre seres masculinos e femininos, humanos e não-humanos, em direção a uma mudança paradigmática em nossas relações sociais e ambientais.We use the theory of complexity to analise gender questions, showing that those are built by society in an exchange of interactions between nature and culture.

Por causa desta conexão entre a autonomia privada e pública, o processo democrática de produção de normas jurídicas apresenta um aparente paradoxo porque os cidadãos tanto podem aprovar as normas motivados pela busca do êxito da racionalidade estratégica como orientados pelo reconhecimento de sua validade através da racionalidade comunicativa, o qual se dissolve, contudo, quando se considera a democracia como um processo aberto para a solidariedade dos cidadãos no mundo da vida.

    Full Text Available Nos últimos anos, a importância do profissional farmacêutico tem aumentada, se tornando fundamental para uma eficiente promoção, proteção e recuperação da saúde do paciente. Um dos principais motivos para a valorização da profissão foi a facilidade de aquisição de medicamentos pela população, o que levava os mesmos ao uso incorreto dos fármacos. A satisfação da população é um fator vital pra a determinação de qualidade do serviço farmacêutico. O objetivo do trabalho é identificar os pontos críticos das atividades farmacêuticas, assim tornando-os visíveis e com isso facilitando a melhora na atuação do farmacêutico. Para que o objetivo fosse visualizado, foram distribuídos 131 questionários a população de Miracema-RJ, que continham 12 itens sobre as atividades farmacêuticas para serem avaliados quanto à satisfação e importância. Através dessas avaliações foram obtidas as médias e os erros-padrão de cada item, como também o déficit de satisfação. Os dados foram apresentados em forma de gráfico, para uma melhor compreensão dos resultados. O principal gráfico do trabalho é o de quadrante, pois ele separa os pontos críticos as serem mudados. Esses pontos foram: prescrição farmacêutica; nebulização; descarte de medicamento vencido. O trabalho ajudará na analise critica com o intuito de melhoria nos serviços farmacêuticos, assim diminuindo o uso incorreto de medicamento.

    Full Text Available Com a demanda pela produção integrada, o monitoramento torna-se fundamental para reduzir ou substituir insumos poluentes na fertilização e no manejo de pragas. Muitos produtos têm sido aplicados em áreas de produção, sem o devido registro ou conhecimento de sua eficiência ou de seu efeito sobre pragas e inimigos naturais. Nesta região, o uso de organomineral é preconizado como alternativa ao uso de fertilizante e possivelmente com efeito nematicida. As avaliações, para verificar o efeito deste produto, foram realizadas, por meio de cinco coletas, no período de 2008 a 2010, em três propriedades, em bananais, cv. 'Williams', introduzidos há oito e 13 anos, dentro do projeto de Irrigação de Formoso, em Bom Jesus da Lapa-BA. Foram coletadas dez amostras compostas de duas subamostras de solo e raízes, em área com e sem a aplicação de organomineral. As propriedades, três, foram denominadas, área 1, 2 e 3. A analise de variância foi feita considerando: três épocas de avaliação, dois tratamentos (com e sem organomineral e três propriedades. O nível de dano foi determinado por meio de escala visual e os dados submetidos à ANOVA. Houve interação significativa entre populações de nematoide no ano e propriedade e entre organomineral e propriedade (P<0,01. Não houve correlação entre nível de dano e organomineral nas áreas 1 e 3. Contudo, houve correlação negativa entre o nível de dano e nematoides na presença de organomineral, na área 3 (P<0,01. Meloidogyne spp. foram as espécies que ocorreram em maior população em Bom Jesus da Lapa-BA. A utilização do organomineral não proporcionou redução significativa na população de nematoides. O nível de dano foi baixo, não podendo ser explicado pelo uso do organomineral. O manejo cultural interferiu no desenvolvimento da população de fitonematoides e de nematoides de vida livre.

A raridade desses tumores tem como conseqüência experiência limitada e, portanto, o conhecimento a respeito destas neoplasias apresenta pontos obscuros. Objetivo: Apresentar os resultados cirúrgicos bem como o seguimento a longo prazo de 6 pacientes com tumores cartilaginosos da laringe, 4 condrossarcomas de baixa malignidade e 2 condromas. Forma de estudo: Retrospectivo não randomizado. Material e método: Cinco dos tumores acometiam a cartilagem cricóide e 1 a tireóide. Os pacientes foram submetidos a laringectomia parcial (4 e total (2, com seguimento de 6 a 30 anos (média-19,5 anos. Resultados: Nenhum dos pacientes apresentou metástase ou morte relacionada ao tumor. A sobrevida alcançada por 5 anos foi de 100% e a por 20 anos, 67%, sendo a comorbidade responsável por tal decréscimo. Conclusões: Nossos resultados reforçam o conceito de que a laringectomia conservadora seja a modalidade ideal de tratamento, reservando a ressecção total para tumores extensos ou casos de recorrência. Há indícios de que 5 anos pode não ser tempo suficiente para observar recorrência no condrossarcoma de baixo grau de malignidade.

    Results of apatite and zircon fission track analysis of samples from the Serra de Santana mesa provide quantitative constraints on the depositional age of the nonfossiliferous Serra do Martins Formation. This unit consists of sedimentary remnants preserved at high elevations on the Borborema Plateau and its distributions and age are considered important in understanding the geomorphological evolution and denudation history of northeastern Brazil following the early Cretaceous breakup. We also report apatite fission track results from post-rift units of the Potiguar Basin (Acu and Tibau formations). Apatite fission track analysis (AFTA) of samples from the Serra do Martins Formation suggests that they reached maximum paleotemperatures around 60 deg C, from which they began to cool some time between 30 and 0 Ma. Due to the high thermal gradients related to the prolonged Cenozoic volcanism in the study area, we hypothesize that the paleotemperatures modeled for those samples may be related dominantly to an anomalous heat flow, rather than to significant burial. Zircon fission track analysis (ZFTA) in two samples of the Serra do Martins Formation yields ages of 135 {+-}18 Ma and 165{+-}40 Ma, but both samples show a significant spread in the data, and the youngest population of grains in these samples are characterized by ages of 83{+-} Ma and 65{+-} Ma, respectively. As the AFTA data show that these ages have not been reset after deposition, the zircon fission track ages must represent inherited provenance ages, demonstrating that those sediments can be no older than Paleocene. Independent lithological observations provide additional support to reject a stratigraphic correlation between the Serra do Martins and Acu formations. Combining the AFTA and ZFTA results, and integrating available geological evidence, we suggest that the Serra do Martins Formation was deposited some time between 64 and 25 Ma (Paleocene-Oligocene). Modeled thermal history solutions from AFTA in the Serra do Martins Formation samples suggest a cooling event during late Cretaceous/early Paleogene, interpreted as reflecting exhumation of sediment provenance terrain. The resulting erosional products form the clastics for the Serra do Martins Formation, which were deposited on an extensive regional planation surface-the Borborema Surface. (author)

    The objective of this work is the study of the natural gamma radiation at the Areia Preta Beach (APB) in Guarapari, state of Espirito Santo, Brazil. The level of this radiation is dependent on the concentration of the radioactive mineral monazite in the sand. Probable risks of the exposure to gamma radiation at the APB were evaluated by the preliminary environmental risk analysis technique. For this purpose were conducted two annual sets monitoring gamma radiation in the APB every two months and so, acquired the seasonal variation of the radioactive levels. Additional/y was investigated the granulometry of the heavy mineral fraction and also carried out electronic microscopic scanning and radiometric age dating of the monazites of the APB, the mineral separation by magnetic susceptibility, and the mineralogic determination of the sediment. In order to gain a more complete picture of the seasonal variation, and, consequently, of the risk of exposure to ionizing radiation at the APB, the radiometric variation was also studied at some other beaches in the same region. The results indicate that the highest radiometric values are measured in summer and the lowest in winter. The radiometric dating of the monazites from the APB revealed the ages of 475 and 530 Ma. The Preliminary Hazard Analysis indicates a minimum risk of excessive radioactive exposition. It would take a period of approximately 870 years of a beach fully crowded to result in one case of bad consequences due to exposure to gamma radiation. (author)

    The global distribution of electric energy in this article, attend to the electric and social exclusion and to regional inequalities in developing countries, with the objective to put up arguments about the question of the social and environmental injustice. It considers the need to plan the balance between the nature budget and the society budget without forgetting the fundamental principles of the thermodynamic and powerful interests involved. Alert to dangers of the exploit the natural resources looking for more energy. Although, the article shows up, the importance of the energy in developing societies. It gives information from IBGE and MME, about the relation between electric exclusion and social exclusion, calling attention to the impossibility to see concrete solutions, out of the social-economic context. Difficulties to construct Amazon indicators were improved on partly by own estimate, because the importance of the Amazon region to the environmental sustainability and the demographic, social and economic difficulties to the electric energy distribution for all Brazilian people.

    By the Plan of Development the concessionaire informs the petroleum regulatory agency (Agencia Nacional de Petroleo Gas e Biocombustiveis - ANP) how it intends to produce hydrocarbons from a field which was declared commercially feasible by such a concessionaire. Therefore, the Plan of Development consists of a very important document for ANP to conduct its supervision duties with regard to operations which usually take place during the development of the production. Because of its relevance within the E and P activities regulatory and supervision system in Brazil, the Plan of Development, its content and the requirements for its record before ANP are regulated by the Brazilian Petroleum Act (Lei n. 9.478/97) and also by the Concession Contracts and a government decree issue by the ANP itself (Portaria 90/2000), which approved a technical regulation on the Plan of Development. This essay will take all these rules into consideration in order to provide a summarized, systematic view of the discipline of the Plan of Development under Brazilian laws and regulations. In this sense, this essay intends to analyze not only the requirements for the preparation, presentation and possible changes in the Plan of Development, but also the legal principles applicable to the plan itself and to the conduct of the ANP before the projects presented by the concessionaires in accordance with such rules.

    Water injection under fracturing conditions is a proved manner of overcoming injectivity loss in reservoirs affected by formation damage. Nevertheless, as shown by Munoz Mazo et al. (2006), there is the possibility of the generated and propagated fractures intercept the producer wells making that the injected water shall be re-circulated into the reservoir instead of its main function which is to drive the oil contained in the reservoir pore space. The objective of this work is to determine the influence of well spacing on the determination of the water injection rate under fracturing conditions, aiming to study its effects on the production performance and the sweep efficiency. To accomplish the work, an analytical model for representing the absolute permeability reduction near the wellbore and a model which reproduces the fracture propagation in a coupled manner are used. In this way the model sensitivity to several well spacing and the injection rate effects are analyzed using the Net Present Value and the sweep efficiency is evaluated as a function of the Recovery Factor. The results show that the water injection under fracturing conditions is an effective way of overcoming the injectivity loss problem and evidence its sensitivity to different spacing between the injector and the producer wells.

    Full Text Available http://dx.doi.org/10.5007/1677-2954.2008v7n2p151O artifo tenciona desenvolver o conceito da amizade como conceito-base de toda Filosofia Prática. Porém pretende apresentar apenas uma entre as várias argumentações possíveis em favor desta concepção: defende que a amizade, no sentido exposto, seja a solução mais convincente ao problema da intersubjetividade. A questão é como a  concepção da subjetividade pode ser entendida a outros indivíduos, se essa, como o autor defende pode ser compreendida priginariamente somente a partir da auto-referência da primeira pessoa. Para isso, ele faz uso do conceito aristotélico do amor amigável enquanto direcionado a um "heterosautos", identificando como seus momentos tanto o conhecimento e o desejo do outro, como o respeito e a benevolência. Os últimos dois momentos são interpretados como "conversão" da consciência dos primeiros. Por meio dessa "conversão da consciência" a consciência do Outro é estabelecida. Como se trata da conversão de uma consciência concreta, tanto cognitiva quanto volitiva, seu resultado não é um conceito abstrato e geral de uma subjetividade diferente da minha, mas uma relação concreta entre indivíduos que implica um compromisso e a partir da qual forma-se um étos específico da comunidade assim estabelecida.

Foram realizadas avaliações microbiológica, enzimática e de cor da polpa, para identificar parâmetros a serem utilizados no acompanhamento da pasteurização. O produto foi submetido a tratamento térmico, em copos de inox, em diferentes tempos (1 a 300 seg e temperaturas (70°C a 90°C, para identificar o efeito destas variáveis sobre parâmetros de qualidade do produto. Constatou-se que os tratamentos não provocaram variação na atividade da peroxidase, contagem de bactérias, bolores e leveduras e cor da polpa. Em seguida foram realizadas pasteurizações, em escala piloto, a 80°C e 90°C; sendo os produtos estocados a 25°C e avaliados durante 120 dias. A redução da atividade da peroxidase e da concentração de bactérias, bolores e leveduras, a níveis aceitáveis, e a manutenção da cor, demonstraram a eficiência dos processos térmicos. A manutenção destes parâmetros, nos níveis aceitáveis, durante a estocagem, confirmou a aplicabilidade dos processos, sem a necessidade da adição de conservante na polpa. A pasteurização da polpa de graviola a 80°C ou 90°C, mostrou ser um tratamento térmico adequado para a conservação do produto, proporcionando 120 dias de vidade- prateleira à temperatura ambiente ( 25°C.

    Full Text Available O artigo contextualiza uma tradição que se apresenta de maneira recorrente nas práticas clínicas da psicologia e da saúde mental: o Mentalismo. O Mentalismo pressupõe uma concepção interiorizada do sujeito em prol de modelos instrumentais de clínica. A partir da crítica ao Mentalismo, os autores examinam outras possibilidades de se lidar não mais com o sujeito essencializado, porém, com os complexos processos de subjetivação. Esta é uma perspectiva clínica que recorrendo a Deleuze, Guattari e à Filosofia da Diferença oferece estratégias mais condizentes com a complexidade do mundo contemporâneo, introduzindo debates éticos, políticos e estéticos na dimensão psíquica.

  2. VOLTAIRE CRÍTICO DA TEOLOGIA DA HISTÓRIA

    Full Text Available A teologia esforça-se por repertoriar e sistematizar o que a revelação e a fé trazem ao crente sobre o problema do sentido da história, da peregrinação através do tempo da humanidade pensada em seu conjunto. Ela enfatiza, não tanto o conhecimento, mas o estado espiritual de felicidade ao qual a humanidade deve ascender antes do fim da vida na terra. Os modernos não aceitam a proposta teológica e têm por ambição descentralizar a história tradicionalmente ordenada por uma visão cristocêntrica do mundo. O historiador, isentando-se da facção, assume o discurso racional sobre a trajetória dos humanos a partir de um novo núcleo referencial interpretativo, a saber, a ideia de humanidade. Voltaire apresenta-se como legítimo representante dessa perspectiva. A história sob o prisma voltairiano é colocada como problema e não como dogmática com características de uma aquisição definitiva. O problema histórico é o de compreender o mundo atual e a humanidade nele inserida. O objetivo, portanto, do trabalho foi apresentar a proposta teológica para a história e a crítica a ela desenvolvida por Voltaire, de forma a evidenciar a originalidade da abordagem moderna do fenômeno histórico.

    Full Text Available O projeto acadêmico de Habermas busca contribuir para a realização das metas emancipatórias da modernidade, através da teoria da ação comunicativa. Portanto, será examinado aqui se o processo de racionalização da sociedade moderna, presente na teoria da ação comunicativa, realmente representa um potencial para a emancipação humana. Primeiramente, pretende-se abordar no respectivo trabalho os principais conceitos que Habermas utiliza em sua teoria da ação comunicativa. Em um segundo momento, serão explorados os elementos fundamentais da teoria da sociedade. Após isso, será analisada a teoria da modernidade e a sua relação com a teoria da sociedade. Tal caminho terá o objetivo de investigar a possibilidade de resgate do projeto da modernidade, ao explicar a possibilidade da teoria da ação comunicativa ser considerada o potenciador emancipatório da sociedade moderna, formando tanto o cidadão como um indivíduo autônomo, preservando a sua identidade pessoal, quanto o cidadão como participante de uma sociedade política, possuidor de uma identidade cultural, étnica, entre outras, que abrange variados grupos sociais.

    Full Text Available O artigo destaca o percurso das manifestações culturais ligadas ao tráfico de drogas no México, de um lugar marginal, de subcultura, na sociedade mexicana das décadas de 1970 e 1980, expressas principalmente através dos narcocorridos e do narcocine, para um lugar no mainstream cultural mexicano, desde o início do século 21, com destaque especial para a narcoliteratura. O aumento da violência, provocado pela guerra ao narcotráfico, produz uma proliferação da temática nos meios de comunicação e se reflete em áreas da cultura como as artes plásticas e a literatura, produzindo um novo tipo de expressão artística ou narrativa, que tanto pode ser oportunista e contribuir para a banalização da violência do narcotráfico como ser crítica e narrar o impacto individual e coletivo do tráfico de drogas, narrar a desenfreada e violenta realidade mexicana sem cair no estilo da imprensa marrom, do folclore ou dos lugares comuns dos romances de ação.

    Full Text Available A videira é uma das principais fruteiras cultivadas em todo o mundo, e atualmente a preferência por uvas do tipo "sem sementes" ou "apirênicas" vem aumentando gradativamente no mercado interno brasileiro. A cultivar 'Romana' (A 1105 tem mostrado grande potencial como nova alternativa de uva de mesa apirênica na região de Jundiaí (SP. No entanto, a qualidade dos cachos tem sido afetada pela ocorrência de chuvas na época da colheita, propiciando a incidência de rachaduras nas bagas ("cracking" e podridões. Levando-se em consideração a viabilidade do cultivo desta uva sob cobertura plástica, foi realizada a presente pesquisa, objetivando-se analisar os parâmetros microclimáticos dentro e fora dos ambientes protegidos e a qualidade do produto na época de colheita. Os valores médios de transmissividade à radiação solar global entre os tratamentos foram decrescentes na seguinte ordem: efeito apenas da cobertura plástica > efeito apenas do sistema de condução da planta > efeito da cobertura plástica + sistema de condução da planta. Logo após a colheita, foram observadas reduções significativas na incidência de podridões, dano profundo e dano superficial nos cachos da videira cultivada sob cobertura plástica. A massa do cacho também foi significativamente maior no tratamento com cobertura plástica. Assim, pode-se concluir que o uso da cobertura plástica para o cultivo da uva 'Romana' (A 1105 foi capaz de melhorar a qualidade dos frutos, principalmente por reduzir significativamente a incidência de podridões nos cachos, importante problema que afetava esta cultivar.The grapevine is an important crop grown worldwide and nowadays the preference by seedless grapes is increasing in the brazilian market. The cultivar 'Romana' (A 1105 is showing great potential as a new seedless table grape for the growing region of Jundiaí, São Paulo, Brazil.

    The reduced scale models design have been employed by engineers from several different industries fields such as offshore, spatial, oil extraction, nuclear industries and others. Reduced scale models are used in experiments because they are economically attractive than its own prototype (real scale) because in many cases they are cheaper than a real scale one and most of time they are also easier to build providing a way to lead the real scale design allowing indirect investigations and analysis to the real scale system (prototype). A reduced scale model (or experiment) must be able to represent all physical phenomena that occurs and further will do in the real scale one under operational conditions, e.g., in this case the reduced scale model is called similar. There are some different methods to design a reduced scale model and from those two are basic: the empiric method based on the expert's skill to determine which physical measures are relevant to the desired model; and the differential equation method that is based on a mathematical description of the prototype (real scale system) to model. Applying a mathematical technique to the differential equation that describes the prototype then highlighting the relevant physical measures so the reduced scale model design problem may be treated as an optimization problem. Many optimization techniques as Genetic Algorithm (GA), for example, have been developed to solve this class of problems and have also been applied to the reduced scale model design problem as well. In this work, Particle Swarm Optimization (PSO) technique is investigated as an alternative optimization tool for such problem. In this investigation a computational approach, based on particle swarm optimization technique (PSO), is used to perform a reduced scale two loop Pressurized Water Reactor (PWR) core, considering 100% of nominal power operation on a forced flow cooling circulation and non-accidental operating conditions. A performance comparison between GA and PSO techniques is performed as it's obtained results to this problem. Obtained results shows that the proposed optimization technique (PSO) is a promising tool for a reduced scale experiments or equipment design, presenting advantages over other techniques. (author)

    To design, modify, and expand surface facilities is a multidisciplinary task which involves substantial financial resources. It can take months or years to complete, depending on the size and level of detail of the project. Nowadays, the use of Next Generation Reservoir Simulators (NGRS) is the most sophisticated and reliable way of obtaining field performance evaluation since they can couple surface and subsurface equations, thus eliminating the need of lengthy multiphase flow tables. Furthermore, coupling a NGRS with an optimizer is the best way to accomplish a large number of simulation runs on the search for optimized solutions when facilities are being modified and/or expanded. The suggested workflow is applied to a synthetic field which reproduces typical Brazilian offshore deep water scenarios. Hundreds of coupled simulation runs were performed and the results show that it is possible to find optimal diameters for the production lines as well as the ideal location for the production / injection platform.

    The ages of hydrothermal events responsible for tin mineralization in the granitic systems from the Rondonia Tin Province are poorly defined so far. Available K-Ar dating in Li-micas of greisens and veins yielded values around 965 Ma, younger than the late mineralized granites ages, around 990 Ma. Electron microprobe U, Th and Pb dating of hydrothermal monazite from the greisen zones of the Palanqueta plutonic system, Bom Futuro tin deposit, yielded an age of 997{+-}48 Ma. Considering that: the K-Ar method is influenced by increasing temperature; critical temperature of Ar retention in micas is 300 deg C; and fluid inclusions and ae {sup 18}O studies indicate, respectively, trapping temperature above 300 deg C and cassiterite crystallization temperature above 400 deg C, we suggest that the K-Ar dating in micas from Rondonia tin deposits are indicative of cooling and closure of the hydrothermal systems. Therefore, ages obtained from U-Th-Pb data in hydrothermal monazite from greisen can be considered a good reference for the tin ore formation in the Bom Futuro deposit, associated with late to post-magmatic processes, and coeval with the end of crystallization of albite granite in the Palanqueta granitic system.

    This study was aimed at investigating the effects of low-dose gamma irradiation on shelf-life extension and phyto sanitary safety of minimally processed red beet with basis on physicochemical; microbiological; chemical and sensory analyses. The samples (Beta vulgaris ssp. vulgaris L.), Early Wonder cultivar, were cultivated in the experimental area of the Horticulture Sector of the Departamento de Fitotecnia of the Instituto de Agronomia, Universidade Federal Rural do Rio de Janeiro, Seropedica, RJ, as part of two experiments performed during the second semester of 2005. In each experiment, 1200 plants (40 per linear meter of terrain) were sowed. Physicochemical analyses (fresh mass; length; average diameter and total soluble solids) of the edible part of the red beets (their tuberous roots) were periodically carried out in order to assess the most appropriate time for harvest by monitoring the development of the plants. Those times were found to be 104 and 73 days after transplanting, respectively. The harvested edible part of the roots were minimally processed and separated in two groups: (1) gamma irradiated (with doses of 0.5; 1.0 and 1.5 kGy) and (2) non-irradiated (control). All samples were stored at 8 degree C. Microbiological analyses were performed during the storage period (22 and 21 days, for experiments 1 and 2, respectively) in order to evaluate the phyto sanitary quality of the samples (Salmonella sp.; coliforms and total count of mesophilic aerobic and lactic acid bacteria). The samples irradiated with 1.0 and 1.5 kGy were found to remain appropriate for consumption for 21 days, as compared to only 7 days for the control. Monitoring of chemical composition was also performed and included the determination of saccharose; glucose; fructose and vitamins B1 and B2. No difference was found between the concentrations of those vitamins in irradiated and control samples at the end of the storage period, whereas significant changes in sugar contents were detected independently of the dose. In addition, physicochemical analyses investigated the evolution of pH; total acidity; total soluble solids and ascorbic acid throughout storage. Samples from experiment 2 were also subjected to sensory analyses for overall appearance and aroma at 4 different post-irradiation times. The results indicated that the samples irradiated with 1.0 and 1.5 kGy remained good for consumption for 20 days. Therefore it can be concluded that the application of those doses extended the shelf life of the samples without harming their nutritional and sensory quality. Finally, the results indicate that the dose of 1.0 kGy is the most appropriate for the conservation of red beet among those tested. (author)

    The complexity of the oxygen reduction reaction (ORR) and its potential losses make it responsible for the most part of efficiency losses at the Fuel Cells. For this reaction the electrocatalyst witch is most appropriated and shows better performance is platinum, a noble metal that elevates the cost, raising barriers for Fuel Cells technology to enter the market. First this work focuses on reducing the amount of platinum used in the cathode, by being replaced by rare earths. The most common methods of synthesis involves a large amount of steps and this work proposed to prepare the electrocatalyst through a simpler way that would not take so many steps and time to be done. Using an ultrasound mixer the electrocatalyst was prepared mixing platinum supported on carbon black and the rare earths lanthanum, cerium and erbium oxides to be applied in a half-cell study of the ORR. The Koutecky-Levich plots shows that among the electrocatalysts prepared the Pt80Ce20/C had the catalytic activity close to the commercial BASF platinum on carbon black, suggesting that the reaction was taken by the 4-electron path. As found in some works in literature, among the rare earth used to study the ORR, cerium is the one witch shows the better performance because it is able to store and provide oxygen. This feature is of great interest for the ORR because this reaction is first order to the oxygen concentration. Results show that is possible to reduce the amount of platinum maintaining the same electrocatalyst activity. (author)

    This dissertation presents the FMEA-DEA analysis application to the air conditioning system of the control room of a nuclear power plant. After obtaining the failure modes, the index associated to the occurrence probability, the severity of the effects and the potential of detention, a priority order is established for the failure modes or deviations. This number is obtained by multiplying the three mentioned index that vary in a natural scale from 1 to 10, where the higher the index, the more critical the situation will be. In this work, it is intended to use a model based on the data envelopment analysis, DEA jointly with the FMEA, to identify the current efficiency of the system and which failure modes or deviations are considered more critical, and by means of the weights attributed for the mathematical modeling to identify which index are contributing more for these deviations. From this identification, improvements can be set, which may consider administrative changes, operator training and so on, thus adding value to the final product. (author)

    The modulated power law process (MPLP) is a three-parameter stochastic point process model that can be used to describe the failures time of reparable systems. While the power law process implies that a system is exactly on the same condition just after a repair as just before a failure, the MPLP allows for the system to be affected both by failure and repair. For this reason this model is adequate for evaluating the recurrent events that incorporate both time trends and effects of past events such as the renewal type behavior. The purpose of this study is to evaluate the MPLP as a model for the rate of occurrence of failures of a repairable system to decide for an extension of qualified life in the context of licence renewal of a nuclear power plant. Standard statistical techniques, such as the maximum likelihood and linear regression models, are applied to estimate parameters of the MPLP. As a conclusion of the study, the MPLP is adequate for modelling rate of occurrence of failures that are time dependent, and can be used where the aging mechanisms are present in the operation of repairable systems.

    Since the radiological accident in Goiania in 1987, the IRD (Institute of Radiological Protection and Dosimetry - IRD / CNEN) has been developing tools to support decision-making processes after a nuclear or radiological accident which leads to an environmental contamination and to an exposure of individuals the public These processes include the establishment of a supporting multicriteria model, which involves the application of protective and remediation measures of contaminated areas in tropical environments. In this study, it was performed an evaluation of the efficiency of these measures in order to determine the consequences of their implementation, based on results obtained from the code SIEM (Emergency Integrated System), which constitutes an environmental mode1 developed at IRD to simulate this type of accident. In order to perform this evaluation, it was first developed a database containing descriptions of various protection/remediation measures, which could be applied nationwide. Afterwards, some basic scenarios were established, considering the environmental, housing and food characteristics of the population of the vicinity of the nuclear power plants in Angra dos Reis (state of Rio de Janeiro). Thus, the accident simulations were carried out separately containing releases of {sup 137}Cs, {sup 90}Sr and 131 I. The results showed that the dose reduction varies according to the extent and the timing of the remediation measure applied. Although it is possible to establish some basic guidelines, generic solutions are not recommended, since the resulting doses are highly dependent on the actual situation. Any decision-making process should be made case by case, according to the actual conditions of the affected area and to the occupation characteristics and use of the affected areas, considering the characteristics of the source term of contamination, the time of the year in which the accident occurs, the local agricultural practices and food habits of real people affected. For both types of area, it was observed that it would be appropriate to assign the security measures according to three criteria: (i) its efficiency in reducing the doses in the first year, (ii) its efficiency in reducing the dose of long-term and (iii) the effect of delay in implementing the measure efficiency in reducing doses. Finally, the results of this work will be complemented in the database in order to provide support for multi-criteria analysis in decisionmaking process after this type of accident. (author)

    This research intended to determine the nuclear parameters a, f, spectral index and neutron temperature in several irradiations positions of the TRIGA Mark 1 IPR-R1 reactor, for use on the parametric method K{sub 0} in the CDTN. K{sub 0} is a monostandard method of neutron activation analysis. It is, on the whole, experimentally simple, flexible and an important tool for accurate and convenient standardization in instrumental multi-element analysis. At the time the parameters were determined at the rotatory rack, lower layer and in the central thimble: alpha was calculated applying the three bare monitor method using {sup 197}Au, {sup 94}Zr and {sup 96}Zr; f determination was done according to the bare bi-isotopic method; neutron temperature was calculated through the direct method using {sup 176}Lu, {sup 94}Zr, {sup 96}Zr and {sup 197}Au and the Westcott's g(Tn) function for the {sup 176}Lu was calculated and the result was interpolated in the Grintakis and Kim (1975) Table, determining the neutron temperature. The procedure to check the parameters consisted in using standard solutions of Au (metal foil, NBS), Lu (LuO{sub 2}, Johnson Mattey Company - JMC) and Zr (ZrO{sub 2} and metal foil, Johnson Mattey Company 99,99% and Zry - 4: 98,14% of Zr, National Bureau of Standard- NBS). Several certified reference materials and two samples of intercomparisons (samples of sediment of the IAEA/ARCAL XXVI project) have been analysed by means of k{sub 0}- INAA in order to verify the efficiency of the method and the quality of the parameters. The certified reference materials were: GXR-2, GXR-5 and GXR-6 of the United States Geological Survey (USGS) and Soil-5, Soil-7 and SL-1 of the International Atomic Energy Agency (IAEA). (author)

    In this paper, the main results of the application of Reliability Centered Maintenance (RCM) to the gas compression systems of Platforms P-09 (Turbine Taurus 60) and P-19 (Turbine Mars 90) are presented. RCM is a method whose central paradigm is to preserve systems' functions, unlike traditional maintenance, which focus on equipment maintenance, without care about systems' functions and the allocation of maintenance resources. A total of 654 components were analyzed at P-19 and 551 at P-09, and about 650 maintenance tasks were established. Besides the results, this paper presents details of the method and some comments about its applicability in other systems. (author)

    Oil is a non-renewable resource and maximizing the efficiency of its use is of the utmost importance, not only to private companies and the generation of their profit, but also to governments and their energy, economic and territorial planning. The aims of this thesis are, on the one hand, to breakdown, by means of a systemic approach, the complexity of the decision-making process in oil exploration and production projects (E and P), explaining, whenever possible, the theories and relationships that underlie their modeling contexts, and, on the other, to create a model - in the case of a specific E and P problem - to support the decision-making process, using the fuzzy logic theory. The variables analyzed include the probability of the exploration process achieving success, the size of reserves, the level or burden of taxation and the price of oil. In the case of the latter, the price of oil, the elements necessary for the elaboration of different scenarios have been provided. Finally, this model has been applied to a case study, providing continuity to previous work and discussing the results obtained. (author)

    Both the suspended solid particles and the bed sediments sorb radionuclides, released in water systems. Sorption is usually represented mathematically by the distribution coefficient that is based in equilibrium between phases. Here the adsorption/desorption kinetics of {sup 60}Co and {sup 137}Cs in sea water were simulated by batch equilibrium experiments with sediments in two points (PT - 01, PT - 02) from Saco de Piraquara de Fora inlet (SPF). For both radionuclides, partition coefficient values (Kd) for the sampling point PT - 02 (509 and 385 L/kg for {sup 60}Co and {sup 137}Cs, respectively) were higher than the values determined for PT - 01 one (426 and 182 L/kg for {sup 137}Cs and {sup 60}Co, respectively). The higher values of Kd of PT-02 reflects the higher CEC (71,4 cmolc.dm{sup 3}) and content of mud < 63 μm (87%) when compared to PT-01 (CEC of 39,5 cmol{sub c}.dm{sup 3}) and mud (55%). In comparison with the values reported in the literature, the found Kd values are low, which may be related to the predominance of kaolinite, which is a clay of low sorption capacity. The Kd values with an increase in temperature of 23 deg C to 27 deg C were similar ({sup 60}Co in PT-02 and {sup 137}Cs in both sediment) or 27 ° C values were higher ({sup 60}Co the PT-01). With increasing temperature to 31 °C Kd values for the two radionuclides showed a decrease. However, increasing temperature increases the desorption of the two radionuclides for both sediments The sorption process is spontaneous and favorable for both sediments and the model of sorption can be fitted by both Freundlich and Langmuir sorption isotherms. The maximum amount of {sup 60}Co that can be sorbed on sediments were 1,64 10{sup -5} moles/g (4,12 10{sup 10} Bq/g) and 2,79 10{sup -5} moles/g (7,03 10{sup 10} Bq/g) to PT-01 and PT-02, respectively, and of {sup 137}Cs 1,99 10{sup -6} moles/g (9,70 10{sup 8} Bq/g) and 6,60 10{sup -6} mol/g (2,87 10{sup 9} Bq/g ) to PT-01 and PT-02. Two areas in SPF can potentially accumulate {sup 137}Cs: sediments located near the effluent discharge and the area located north of this site. An area in the interface of SPF and the bay of Ribeira would potentially the best accumulated of {sup 60}Co. (author)

    The availability of immunoassay methodology for proinsulin is important to define its physiological and pathophysiological significance in humans. Serum concentration of proinsulin are elevated in patients with type II Diabetes Mellitus (NIDDM) and recently diagnosed Type I, so a raised circulating concentration of proinsulin may serve as an early indicator of {beta} cells dysfunction. recently, in NIDDM the serum concentrations of proinsulin and its B-chain-C-peptide junctional split form, des (31-32), were found to correlate with diastolic blood pressure, a risk factor for cardiovascular disease. The development of a sensitive and specific radioimmunoassay (RIA) methodology for proinsulin has been difficult due to its low concentration in serum and the presence of proinsulin conversion intermediates in fluids and tissues. Also other potentially cross-reactive peptides, including insulin and C-peptide, can interfere in the assay. This work describe a highly specific human proinsulin RIA developed by using biosynthetic human proinsulin (hPI) as immunogen, standard and tracer. (author) 133 refs., 17 figs., 36 tabs.

    The present work described a new methodology for modelling the behaviour of the activity in a 4{pi}{beta}-{gamma} coincidence system. The detection efficiency for electrons in the proportional counter and gamma radiation in the NaI(Tl) detector was calculated using the Monte Carlo program MCNP4C. Another Monte Carlo code was developed which follows the path in the disintegration scheme from the initial state of the precursor radionuclide, until the ground state of the daughter nucleus. Every step of the disintegration scheme is sorted by random numbers taking into account the probabilities of all {beta}{sup -} branches, electronic capture branches, transitions probabilities and internal conversion coefficients. Once the final state was reached beta, electronic capture events and gamma transitions are accounted for the three spectra: beta, gamma and coincidence variation in the beta efficiency was performed simulating energy cut off or use of absorbers (Collodion). The selected radionuclides for simulation were: {sup 134}Cs, {sup 72}Ga which disintegrate by {beta}{sup -} transition, {sup 133}Ba which disintegrates by electronic capture and {sup 35}S which is a beta pure emitter. For the latter, the Efficiency Tracing technique was simulated. The extrapolation curves obtained by Monte Carlo were filled by the Least Square Method with the experimental points and the results were compared to the Linear Extrapolation method. (author)

    The surfactants, amphipathic compounds capable of reducing the surface tension of aqueous media, find application in many industries, especially in the petroleum, cosmetic and food, such as dispersants, emulsifiers and surfactants. With the necessity of environmental preservation, surfactants of micro-organisms origin, in substitution of synthetic surfactants, have become very attractive, since they are biodegradable and less toxic although their production costs are still high because of the substrates used and of the purification processes involved. Considering the need to reduce costs associated with the production of microbial surfactants, a strain of bacteria of the genus Pseudomonas, isolated from the port area was cultured in medium containing low-cost agro-industrial wastes, molasses and corn steep liquor, as substrates according a central composite rotatable design (CCRD) in order to evaluate the influence of independent variables molasses and corn steep liquor concentrations on the response variable surface tension. The biosurfactant was able to reduce the water surface tension from 71 mN / m to values around 27.5 mN / m. The dispersion ability and the capacity of oil removal of the surfactant was demonstrated. The possibility of application of biosurfactants in the remediation of oil polluted environments motivates the advancement of research to develop this technology for effective use in treatment of contaminated soils and waters.

    Objective: to compare the performance of the T1, T2, STIR and DWIBS (diffusion-weighted whole-body imaging with background body signal suppression) sequences in the staging and follow-up of pediatric patients with Hodgkin's lymphoma in lymph node chains, parenchymal organs and bone marrow, and to evaluate interobserver agreement. Materials and methods: the authors studied 12 patients with confirmed diagnosis of Hodgkin's lymphoma. The patients were referred for whole body magnetic resonance imaging with T1-weighted, T2-weighted, STIR and DWIBS sequences. Results: the number of lymph node sites characterized as affected by the disease on T1- and T2-weighted sequences showed similar results (8 sites for both sequences), but lower than DWIBS and STIR sequences (11 and 12 sites, respectively). The bone marrow involvement by lymphoma showed the same values for the T1-, T2-weighted and DWIBS sequences (17 lesions), higher than the value found on STIR (13 lesions). A high rate of interobserver agreement was observed as the four sequences were analyzed. Conclusion: STIR and DWIBS sequences detected the highest number of lymph node sites characterized as affected by the disease. Similar results were demonstrated by all the sequences in the evaluation of parenchymal organs and bone marrow. A high interobserver agreement was observed as the four sequences were analyzed.

    To improve the standard of society's quality of life, it is necessary to improve the quality of distributed energy and its inherent services within a sustainability process. Among different technological routes that produce more sustainable energy are the fuel cells - also known as combustible batteries. The Global Environment Facility (GEF) has identified the fuel cells as a potential technology to reduce, in the future, the effect of greenhouse gases in both developed and developing countries. Although there are various types of fuel cells, the most used technology for research studies on fuel cells is the Polymer Electrolyte Fuel Cells (FEMFC). However, economic issues - related to the high cost of the membrane's materials and of the catalysts of groups of platinum metals - are still some of the obstacles that need to be overcome for this technology to be more accessible. There are also socio-environmental aspects related to the impacts caused by the extraction, the use and the destination of these metals. Taking in consideration the challenges of complying with the demands of the market and the society as well as with the growing tendency of more rigid patterns of environmental control, the objective of the present work is to show the tool of environmental management - Life Cycle Assessment (LCA) - and its importance on the pursuit for socio-economic and environmental alternatives feasible to the recycling of the catalysts of platinum of the PEMFC. This way, it intends to collaborate to the progress of the knowledge about environmental and socio-economic subjects related to the productive process of the PEMFC. (author)

    In this work it was possible to analyze the perception of risks associated with existing processes in the high-dose rate brachytherapy and teletherapy using linear accelerators of radiotherapy services in the metropolitan area of Rio de Janeiro, through the combined use of two proposed methods: FMECA and risk matrix, using a general analysis and other more specific ones. The database software (SEVRRA) was used to identify possible existing processes in radiotherapy services (brachytherapy and teletherapy) and to classify the sequence of events in risk levels. The risk levels were analyzed at each stage and sub-stage, present in the treatment of patients undergoing high dose rate gynecological intracavitary brachytherapy and teletherapy treatments with the use of linear accelerators applying electron or photon beams in order to establish recommendations to the risks of highest priority for each case. The results show that although the procedure of high dose rate brachytherapy be automated and less susceptible to errors or failures, daily, one can still find considerable amounts of processes with worrying levels of risk perception. The processes that are more subject to radiological accident risks was associated with procedures, for of which the majority of the failures record and planning step of the treatment. The controls analyzed showed low efficiency, warning of the need to seek and implement new more efficient controls in routine brachytherapy for each participant service. About teletherapy procedure it was found that most of the failures were related to the registration and planning of treatment and equipment stages. The controls analyzed to teletherapy showed a poor result with a first type of analysis performed by suggesting a new type of more appropriate analysis. With a second type of analysis, these controls could be better analyzed and showed an order of importance according to a percentage of efficiency. Controls such as 'Double-check', 'Weekly image portal' and 'Weekly medical review of patients', were highlighted as the most present and effective in routine radiotherapy procedure. These results have great relevance for this type of methodology, since their practical application, together with its potential risk identification and classification, confirm their feasibility of use in routine services in the metropolitan area of Rio de Janeiro, as well as in other locations, seeking to meet national and international recommendations for safety and radiation protection.

    The Oil Industry includes the practice of activities that involve high costs and risks to the environment. Thus, there is a need to regulate, supervise and, when necessary, restrain the performance of the sector with the aim of avoiding any acts that impact the environment. According to the Federal Constitution which provides in its article 225, it is responsibility of the Government to apply the penal and administrative sanctions, regardless of the obligation to repair the damage, the responsible, be it natural or juridical person, the conduct and activities considered harmful to the environment. These sanctions are the means of protecting the environment, namely civil, criminal and administrative protection. In this paper, we restrict ourselves to address the administrative supervision of the environment, through the notions pertaining to the police power of environmental and administrative responsibility, emphasizing that theme in its assumptions and its legal nature. Then review the administrative sanctions under infra constitutional level, alluding to that available to the specific legal matters, ie, Law 9.605/98 and Decree No 6.514/08. Finally, we explain the performance of the Instituto Brasileiro do Meio Ambiente e dos Recursos Naturais Renovaveis (IBAMA) in the defense of legal and common usage that is the environment.

    This study examines the characteristics of the water from the upper Tiete, as an input in the form of drinking water produced in eight stations, water treatment plant (WTP), an input for hydropower generation and wastewater generated by different anthropogenic activities. The most important problem of this basin is the wastewater that is released in the Pinheiros river and due to the deficit of 32.41 m3/s (2008) in the treatment of sewage in the metropolitan region of Sao Paulo ('RMSP') which produces one pollutant load of 920 thousand kilograms of BOD per day. The Pinheiros river's flow during the floods and drought has the same destination, the Billings reservoir. However, the legislation for floods and drought periods are different. The first case - floods occurs by the action of full control of the metropolitan region and is supported by the Joint Resolution of Secretaries of State of Sao Paulo (SEE-SMA-SRHSO on 13/03/96) that allows the pumping of water in the following emergencies: (1) estimates of flow of the Tiete river at the point of its confluence with the river Pinheiros, above 160 m3/ s; (2) raised level above 30 cm water level at the confluence with the river Pinheiros. The second case - drought, the Metropolitan Company for Water and Energy (EMAE) Project proposed flotation of the Secretary of State for the Environment (SMA, 2004) to treat 10 m3/ s water originating channel Pinheiros (set/2007 the set / 2008) by means of flotation technology in flow. Using information based on Environmental Sanitation Great Sao Paulo (SANEGRAN) and data from the operation of the prototype flotation system Pinheiros-Billings (Project QAPB), concluded that the environmental impact of the reservoir Billings for the load of pollutants (mass per second) pumped after the flotation of the Pinheiros river water was always lower than that observed in the flood control operation. The treatment presented by flotation removal of 91% for total phosphorus, 90% for E. coli, 53% for organic matter and 14% for ammonia nitrogen. There was an increase of 34% for oxygen and a decrease of 46% in turbidity. The analysis of the technical operation of the lift system Tiete-Billings, held in the AHP-Analytic Hierarchy Process, showed that 65.62% of the water entering the reservoir Billings can be used to generate electricity, while 34.38% this water can be used to supply the 'RMSP'. The feasibility study compared the economic cost of the flotation process with the cost of input of water from other sources and concluded that the cost of the flotation of the waters of the Pinheiros river to serve the supply of the metropolitan region is economically viable.

    Fifteen samples of ground black pepper (Piper nigrum L.) purchased in Sao Paulo local stores, were submitted to irradiation in doses of 3, 6 and 10 kGy. All irradiated samples, including non-irradiated controls, were submitted to counts of yeasts and molds, aerobes (APC), coliforms and mesophilic aerobic spore formers (MASC), using conventional plate count methods and PETRIFILM {sup TM} plates. For yeasts and molds count, acidified potato dextrose agar (PDA) an PETRIFILM {sup TM} PFYM plates were used. For aerobes, plate count agar (PCA) and PETRIFILM {sup TM} PFAC plates were used. Violet red bile agar (VRBA) and PETRIFILM {sup TM} PFEC plates were employed for enumeration of coliforms. Counts of these groups of microorganisms obtained through the traditional plating procedures did not differ significantly from those using the corresponding PETRIFILM {sup TM} plates. In samples submitted to irradiation, a dose of 10 kGy caused a decrease of the yeasts and molds count from 10{sup 4}-10{sup 5} to less than 10 cfu/g. The same dose caused a decrease of the aerobic counts from 10{sup 7}-10{sup 8} to 10{sup 2}-10{sup 3} cfu/g, of coliforms from 10{sup 4}-10{sup 5} to less than 10 cfu/g and MASC from 10{sup 6}-10{sup 7} cfu/g to 10-10{sup 2} cfu/g. The introduction of a injury repair step in the counting procedure resulted in a 32 to 89% increase in the number of coliforms. However, this additional step did not improve significantly the counts of MASC. After 270 days of storage of samples irradiated with 3 kGy, a decrease in the yeasts and molds population from 10{sup 3} to 20 cfu/g was observed. The APC population in these samples was reduced from 5,0x10{sup 6} to 2,4x10{sup 4} cfu/g; in those irradiated with 6 kGy the reduction was from 4,0x10{sup 4} to 5,0x10{sup 3} cfu/g and in those irradiated with 10 kGy the counts were reduced from 30 to less than 10 cfu/g. After the same time of storage, the coliform population in non irradiated samples decreased from 2,8x10{sup 5} to 1,5x10{sup 4} cfu/g and from 9,1x10{sup 3} to 20 cfu/g in those irradiated with 3 kGy. Similarly, the MASC decreased from 2,8x10{sup 4} to 5,6x10{sup 3} cfu/g in samples irradiated with 3 kGy and from 1,2x10{sup 4} to 6,6,x10{sup 2} cfu/g in samples irradiated with 6 kGy. (author)

    A great application of intelligent systems is in control of the electric power consumption of enterprises. For the assessment of the way that the company uses the electricity there are two indices which are called load factor and power factor. To facilitate the assessment of the performance of electric power consumption by the companies it is interesting that there is a single index indicating globally as energy is being used by the same. The goal of this work was to develop a software to assist laying poultry companies in the region of Bastos in more rational and efficient use of electric energy. For this, a system has been developed called Fuzzy Energy integrated environment developed with Delphi 2010. For the determination of fuzzy factor (situation of the company), we used a fuzzy system prepared in advance. The data collected over a period of 3 years helped the system programming. The software was able to present the situation of the company studied in a manner accessible to the user, and their results were tested accuracy 100 according to fuzzy system. With the inference method of Mandani, unable to create a general simulation of all relevant points of enterprise data. (author)

    Royalties and the windfall profits tax derived from petroleum exploration and production in Brazil are government take with huge impacts on the financial health of the state and cities of Rio de Janeiro. Considering the relevance of oil revenue, this study evaluates the significance of the amount transferred between government levels, comparing the current allocation system with international cases. The implemented methodology to reach the result has been the evaluation and data analysis, based on the finances of the state of Rio de Janeiro and the cities that have common borders with the Campos Basin. Furthermore, international cases have been analyzed. Findings indicate that, on one hand, the centralization of the oil revenue at federal level guarantees a better capacity to absorb uncertainties and the variation on the amount received; on the other hand, under a local level, it's possible to identify and better supply the local necessities and scarcities, not to mention, realize a more effective control. In the Brazilian case, this point is even more relevant, as far as debate concerning the distribution of government take cannot be done without considering a broader tax reform, especially in the case of petroleum, which should be associated with the incidence of ICMS on the destination.(author)

    The pre-rift/rift transition is represented by the Serraria and Barra de Itiuba formations. This interval was analyzed through qualitative and quantitative descriptions of cores, electric log analysis and studies of outcropping sections. The integration of surface and subsurface data allowed the stratigraphic characterization of sandstone bodies in the pre-rift/rift. These sandstones bodies were deposited by fluvial braided, lacustrine and deltaic systems (delta plain, delta front and pro delta). The sedimentary deposits characterized in the Serraria Formation are of channel, flooding of the fluvial system and eolic. The upper interval of this formation is characterized by to coarse medium-grained sandstones identified as the Caioba Sandstone. The Barra de Itiuba Formation contains lake, pro delta, frontal bar, distributary mouth, crevasse and distributary channel deposits. The sandstone units were specifically characterized in terms of their potential reservoir quality, and they were characterized the reservoirs R1 (good to medium quality) and Caioba (good quality) from the pre-rift phase, and reservoirs R2 (medium quality) and R3 (medium to good quality) from the rift phase. The reservoirs from pre-rift phase phase show the better reservoirs quality potential of the pre-rift/rift transition in the Sergipe-Alagoas Basin. (author)

    A sample of 11 patients showing temporomandibular joint disease, in one or both sides, was selected. Clinical examinations were performed on patients to define which side was the most compromised by the disease. Only the worst side was chosen to be treated by the laser therapy. The laser unit used was a diode laser (Al-Ga-As) which the wave length was 810 nm (infra-red spectrum). Irradiations were done in tree points of TMJ, with 22,5 J/cm{sup 2}; two points in the masseter muscle, with 15 J/cm{sup 2}; and tree points in the temporal muscle, with 7,5 J/cm{sup 2}. All points were irradiated for 30 seconds. The other side, of lesser complain, received a sham therapy. Patients answered to a questionnaire about the level of pain they were suffering just before and after each irradiation. Besides that mouth opening was measured, from the central lower incisor to the upper central incisor, before and after the therapy , using a digital calliper. The treatment was done during two weeks, tree irradiations with 48 hours interval in the first week, and two irradiations with the same interval in the second week. The electromyography evaluation of the masseter and anterior temporal muscles was done before and after the first irradiation and before and after the last irradiation. Patients reported improvement in relation to the level of pain, mainly after the forth irradiation, and the level of pain decreased until the last day of treatment. In relation to the degree of mouth opening, the majority of patients showed a significant increase, mainly after the fifth day of irradiation. In regard to the electromyography results, we could notice that for the temporal anterior muscle there was a tendency of improvement in the electromyographic pattern, when comparing the treated side to the non-treated side , but there were not significant results. In relation to the masseter muscles we could not see any significant results between both sides. (author)

    In 2004, it was established the National Program for Production and Use of Biodiesel (PNPB) which encourages the participation of family farming in the biodiesel production chain, boosting rural development and social inclusion of these workers. From 2008 on, the PNPB decided that it would be mandatory the add 2% of biodiesel into diesel, named B2, and from 2010 on, the obligation of B5 was imposed. However, after two years of mandatory mixing, over 80% of the raw material for biodiesel production comes from large producers of soybeans in the Midwest. Thus, the focus of this study was to identify the main constraints and opportunities for family farming to participate in the program, based on the analysis of design parameters and guiding PNPB and the main stages of the agricultural seeds in the semi-arid. The study focused on Ceara as it is the state that greatly encourages the participation of small farmers through subsidies associated with the adoption of agro-ecological farming practices (author)

    The insertion of calcium carbonate (CaCO{sub 3}) in polypropylene compound is a thoroughly known technique widely studied in the academic area and in the industry. Its wide application is due, mainly, to increase mechanical properties with low manufacturing cost. These improvements in this polymer make it more versatile and competitive compared to other expensive polymers. In this study, the incorporation of four types of CaCO3 from the same manufacturer were compared and the focus was on the size of this mineral filler. Furthermore, it was analyzed the interaction of graphitized polypropylene with maleic anhydride (PP-g-MA) in the same samples. All these samples were analyzed by WAXS and SEM. The physical properties of tensile strength and impact were also analyzed. It was observed from this study that the smallest CaCO3 produced with PP-g-MA resulted in better physical properties with the formation of a crystalline phase beta, as originally studied by other authors using other raw materials.

    Full Text Available A strain of Bacillus pumilus was isolated and identified from water samples collected from a small affluent of the Amazon River. Type II restriction endonuclease activity was detected in these bacteria. The enzyme was purified and the molecular weight of the native protein estimated by gel filtration and SDS-PAGE. The optimum pH, temperature and salt requirements were determined. Quality control assays showed the complete absence of "nonspecific nucleases." Restriction cleavage analysis and DNA sequencing of restriction fragments allowed the unequivocal demonstration of 5´GAG¯CTC3´ as the recognition sequence. This enzyme was named BpuAmI and is apparently a neoschizomer of the prototype restriction endonuclease SacI. This is the first report of an isoschizomer and/or neoschizomer of the prototype SacI identified in the genus Bacillus.Uma linhagem de Bacillus pumilus foi isolada e identificada de amostras de águas coletadas em um pequeno Igarapé do Rio Amazonas. Foi detectada atividade de restrição do tipo II nesta bactéria. A enzima foi purificada e o peso molecular da proteína nativa foi estimado por gel filtração e por eletroforese em gel de poliacrilamida. Foram determinados, o pH e temperatura ótimos e as necessidades de sais. Os ensaios do controle de qualidade mostraram uma ausência completa de "nucleases não específicas". As analises das clivagens e o seqüenciamento do DNA dos fragmentos de restrição permitiram uma demonstração inequívoca de que 5´GAG¯CTC 3´ é a seqüência de reconhecimento da enzima. Esta enzima foi denominada de BpuAmI e aparentemente é um neoesquisômero da enzima protótipo SacI. Este é o primeiro relato de um isoesquisômero e/ou neoesquisômero da enzima protótipo SacI identificada no gênero Bacillus.

    Full Text Available A ideia de “liquidez” enquanto característica da fase actual da modernidade, presente na obra mais recente de Zygmunt Bauman, convida a uma leitura cruzada entre este autor e Keynes. Quer em Bauman, quer em Keynes, a liquidez aplica-se a relações que podem ser facilmente revertidas, ou revertidas a baixo custo, e a sistemas que, sendo caracterizados pela precariedade dos laços que unem os seus elementos constituintes, tendem a ser, eles próprios, instáveis e precários. Em ambos os autores, a liquidez e a especulação surgem como respostas racionais à incerteza e, ao mesmo tempo, como estratégias individuais que contribuem para o aumento do risco sistémico. As duas abordagens são complementares e coerentes. A leitura cruzada sugere a existência de mecanismos da liquidez transversais a diferentes domínios institucionais cuja identificação é aqui ensaiada.

    Full Text Available El presente estudio fue realizado en el Laboratorio de Mecanización Agrícola del Departamento de Ingeniería Agrícola de la Universidad Federal de Viçosa, con el objetivo de separar los frutos de café verde de los de cereza, buscando propiciar una mejor calidad de la bebida. En este experimento se evaluó el comportamiento de los frutos de café, en la caída libre sobre superficie de madera inclinada, considerando las diferentes distancias de rebote alcanzadas, de acuerdo con la variación de los factores: altura de caída, inclinación de la superficie de impacto en los estadios de maduración de los frutos de café arábica, variedad Catuai Rojo. El experimento fue dividido en tres etapas. La primera parte del estudio fue observar el efecto del ángulo de la superficie de impacto de separación de los frutos de café. La altura de caída fue fijada a 80 cm y evaluados los ángulos de la superficie de impacto de 10º , 15º , 20º , 25º , 30º, 35º y 40º, respectivamente, utilizando, para cada una de las seis repeticiones, una muestra que contiene diez frutos de café . Para determinar con cuáles inclinaciones se obtuvieron las mayores distancias de rebote, se partió de los frutos verdes de cerezas para saber la altura de caída que proporciona un aumento en la diferencia de rebote de los frutos, después del impacto en la tabla. Esta segunda etapa consistió en un ensayo del comportamiento de los frutos, considerando las alturas de caída de 40 cm, 80 cm y 120 cm, se utilizaron seis muestras, conteniendo quince frutos de cada uno. A partir de estos ensayos se pudo concluir que la altura de caída libre de 80 cm y la inclinación de la superficie de impacto de 30º proporcionan una mayor eficiencia de separación de los frutos verdes de los cerezos para el café estudiado

    Full Text Available All too often literary structures in the New Testament are passed off in scholarly literature as mere literary niceties serving only aesthetic ends. Too little consideration has been given to the possible exegetical signif­ icance of such structures to the interpretation of biblical texts. This article is an attempt to present an apologetic for the value of stylistic analysis of New Testament texts as an aid in interpreting the New Testament. It must be kept in mind that to the biblical authors, artistry in the use of stylistic structures was not an end in itself, but a means towards more effective communication of the message.

É a história de uma rutura progressiva entre o homem e o entorno, acelerada pela mecanização. Mediante a tecnociência, a natureza artificializada alcança seu estágio supremo, onde a natureza e o homem tornam-se reciprocramente hostis. Com a globalização da economia, da política e da cultura, não há mais relações totalizantes entre a sociedade e o meio. A natureza tecnicizada se impõe como algo abstrato, exigindo um discurso. A questão do meio ambiente é um aspecto dessa evolução e reclama um estudo abrangente, para permitir uma correta interpretação. Para alcançar essa interpretação, a universidade deve fugir dos raciocínios técnicos e conformistas e enfrentar o entendimento do mundo como um todo.With man on Earth, Nature is being permanently rediscovered through the creation of social nature.

    Full Text Available No final da década de 80 a Gestão da Qualidade Total (GQT era apresentada como capaz de resolver todos os problemas e atender a todas as necessidades da gestão das organizações. Buscando solucionar problemas de gestão não equacionados pela GQT, muitas organizações começam a adotar o Balanced Scorecard (BSC. Uma questão ainda não discutida com profundidade no mundo acadêmico é a viabilidade de integração desses dois modelos. O presente artigo discute a possibilidade de integração dessas duas ferramentas, verificando as melhorias que podem alcançar, principalmente no gerenciamento da estratégia da organização. Assim sendo, realizou-se estudo de caso no Caesar Park Hotel Fortaleza (CPHF, empresa que vêm adotando com sucesso os dois modelos. A pesquisa revela que é possível integrar os princípios da GQT com os do BSC, à medida que os fundamentos de ambos se complementam, sendo assim a utilização conjunta das ferramentas propicia melhor gerenciamento da estratégia da organização.In recent years, many organizations have been managed according to the principles of Total Quality Management (TQM, which became known around the globe in the 1980's, when looking for explanations for the so-called "Japanese miracle". TQM was presented as being capable of solving all problems and attending to all company management needs, a stage that seems outdated now. In the search for a model that would allow them to analyze and follow up the implementation of organizational strategies, without remaining limited to Quality indicators, many companies started to adopt the Balanced Scorecard (BSC. Companies using TQM question whether it is viable together with the BSC. In order to contribute to a solution to this question, this article discusses the possibility of aligning these two tools. Therefore, a case study was carried out at the Caesar Park Hotel Fortaleza, a company that implanted TQM in 1997 and started to adopt the BSC in 2000. The

    Full Text Available A incidência da cisticercose cerebral entre os consulentes orientados para o Ambulatório de Neurologia da Faculdade de Medicina de Ribeirão Prêto é muito alta. Trata-se de moléstia que, pela gravidade de seus sintomas, pela facilidade de infestação e pela precariedade dos recursos terapêuticos, representa um probiema individual e social grave nesta região. Muitos aspectos da moléstia já foram esclarecidos, sendo grande a contribuição de autores brasileiros. Certas feições da moléstia, porém, ainda comportam maiores estudos. É nosso objetivo oferecer uma contribuição ao estudo das formas intraventriculares de neurocisticercose. Relatamos as observações de 4 pacientes com queixas de hipertensão intracraniana periódica e com achados liquóricos e radiológicos compatíveis com a suspeita de cisticercose cerebral. Exames subsidiários (pneumencefalografia ou ventriculografia mostraram que em dois dêstes pacientes havia bloqueio do aqueduto de Sylvius (casos 3 e 4 e que, nos outros dois, havia exclusão de um ventrículo lateral por bloqueio do buraco de Monro (caso 1 e da confluência dos cornos temporal e occipital (caso 2.

O guaraná (Paullinia cupana em pó objeto deste estudo, foi obtido em "spray dryer", a partir de um extrato hidroalcoólico. Ajustaram-se os pontos experimentais das isotermas de adsorção de umidade do produto à 15°C, 25°C e 35°C, por análise de regressão não-linear. Para estudar o efeito da temperatura nos parâmetros dos modelos utilizaram-se regressões dos tipos: linear, exponencial, logarítmica e inversa. Utilizou-se para fazer os ajustes o aplicativo STATGRAPHICS 5.1. Entre os modelos testados os que apresentam melhores resultados foram as equações de Handerson, Oswin e Mizrahi.Eight biparametric mathematic models of the literature and widely applied in the prediction of moisture adsorption isoterms were analised. The guarana (Paullinia cupana powder used in this study, was obtained in spray dryer from a hidroalcoholic extract. The experimental points of the moisture adsorption isotherms of the product at 15°C, 25°C and 35°C were fitted by non-linear regression analysis. To study temperature effect in the parameters of the models were used linear, exponential, logarithmic and inverse regressions. They were also used to fit the software STATGRAPHICS 5.1. The Handerson, Oswin and Mizrahi equations presented the best results among tested models.

    The regulatory bodies request risks evaluations for nuclear and radioactive licensing purposes. In Brazil those evaluations are contained by the safety analysis reports requested by the Brazilian Nuclear Energy Commission (CNEN), and risk analysis studies requested by the environment organisms. A risk evaluation includes the identification of the risks and the accident sequence which can occur, and the estimation of the frequency and his undesirable effects on the industrial installations, the public, and the environment. The identification and the risk analysis are particularly important for the implementation of a health, environment and safety integrated management according to the regulation instruments ISO 14001, BS 8800 and OHSAS 18001. The utilization of the risk identification techniques and the risk analysis is performed at the non nuclear industry, in a non standard form by the various sectors of an enterprise, diminishing the effectiveness of the recommended actions based on risk indexes. However, for the nuclear licensing, the CNEN request through their regulatory instruments and standard formats, that the risks, the failure mechanisms and detection be identified, which can allow the preventive and mitigate actions. This paper proposes the utilization of the FMEA (Failure Mode and Effects Analysis) technique in the licensing process. It was implemented a software through the Excel program, using the Visual Basic for Applications program which allows the automation and the standardization of FMEA studies as well

Análise bibliográfica, estudo crítico do filme clube da luta e leituras pertinentes para a colocação da patologia transtorno dissociativo referente ao protagonista da obra cinematográfica. O filme Clube da luta, que foi tomado por nós para analise, conta o drama vivido por Jack (Edward Norton, funcionário de uma grande empresa de seguros, que levava uma vida rotineira dedicada exclusivamente ao trabalho e se tornou fundador de um clube de luta livre clandestino, em parceria com Tyler Durden (Brad Pitt, ficando claro, ao longo da trama, que ele desenvolveu um processo de dissociação de sua personalidade. Tyler Durden e Jack eram duas faces de uma mesma pessoa. De acordo com o CID-10, o Transtorno Dissociativo de Identidade reflete um fracasso em integrar vários aspectos da identidade, memória e consciência. Cada estado de personalidade pode ser vivenciado como se possuísse uma história pessoal distinta, autoimagem e identidade próprias, inclusive um nome diferente. Em geral existe uma identidade primária, portadora do nome correto do indivíduo, a qual é passiva, dependente, culpada e depressiva. A crítica ao drama acontece por sete principais vias: comprar, sofrer, apanhar, roubar, destruir, transar e encontrar o outro.

    autores sobre productividad en enfermería y reflexiona sobre los resultados y hallazgos encontrados. Destaca como resultados que la productividad se relaciona y se centra en la eficiencia, la eficacia y la efectividad, aspectos que se vinculan con los productos o intervenciones que realiza enfermería, los cuales es necesario conocer y dar a conocer exactamente, así como establecer sus logros. De igual manera se aprecia la relación de la productividad en enfermería con los conceptos de calidad, ambiente laboral y costos, y que las principales características comunes que relacionan, determinan, afectan o definen la productividad en enfermería son condiciones laborales, condiciones personales y factores externos.Esse artigo apresenta aspectos da pesquisa sobre produtividade na enfermagem, realizado como trabalho de formatura pelas estudantes de enfermagem, Castellanos, García eGómez (1, da Faculdade de Enfermagem da Universidade Nacional da Colômbia, e dirigida pela professora Myriam Abaunza de González quem é consciente da importância de realizar estudos sobre enfermagem relativos à produtividade. A pesquisa coloca como principal objetivo identificar a definição da produtividade no contexto da enfermagem e utiliza como método a monografia, mediante uma matriz de analise bibliográfico. Na discussão a pesquisa se refere a conceitos e pesquisas de diferentes autores sobre produtividade no contexto da enfermagem e reflete sobre os resultados e achados encontrados. Salienta como resultado que a produtividade está relacionada e focada na eficiência, na eficácia e na efetividade, aspectos vinculados com os produtos ou intervenções realizadas na área da enfermagem, os quais, conjuntamente com seus logros, devem ser conhecidos e dados a conhecer com precisão. Igualmente, evidencia-se a relação da produtividade no âmbito da enfermagem com os conceitos de qualidade, ambiente de trabalho e custos, e que as principais características comuns

    Full Text Available O presente artigo tem como objetivo uma abordagem crítica de um dos primeiros ensaios de Hölderlin, escrito por volta de 1794-5, intitulado Juízo e Ser. Nesse período, fundamentar o sistema kantiano através de um primeiro princípio tornou-se um dos principais incentivos dos desenvolvimentos teóricos do idealismo alemão. A filosofia de Fichte e Schelling, bem como a de Hölderlin, podem ser compreendidas por esse viés. Entretanto, o último chega a soluções bastante diferentes dos demais, culminando com a negação da possibilidade de um princípio unificador para qualquer sistema filosófico. Assim, contra os incessantes esforços dos idealistas alemães para apreender a totalidade do real em termos conceituais, através de um primeiro princípio, normalmente caracterizado como o Eu, o Sujeito, o Eu absoluto, Hölderlin defende a incognoscibilidade de qualquer conceito unificante do real. A realidade enquanto unidade primordial não pode ser apanhada pelo discurso teórico, nem conhecida, nem aprisionada em conceitos, revelando-se apenas através de uma intuição intelectual de cunho estético. Esse conceito eminentemente anti-kantiano constitui a peça chave para o entendimento do pensamento hölderliniano. Ele justifica, em última instância, o privilégio da poesia e da linguagem poética em detrimento do discurso conceitual e mostra, com isso, que há uma coerência interna entre os ensaios teóricos de Hölderlin e suas obras literárias.

    Full Text Available São divulgados os primeiros resultados da avaliação da dinâmica da epidemia da AIDS no Brasil através de técnicas de análise da distribuição espacial. São revisadas questões metodológicas, apontando as dificuldades de estabelecer regiões geográficas homogêneas no Brasil. Descrevem-se tendências recentes da dinâmica da epidemia da AIDS no Brasil - pauperização, interiorização e alteração na participação proporcional das categorias de exposição. Avalia-se a distribuição de casos de AIDS por Unidades da Federação (UFs, confeccionando-se mapas relativos à disseminação da epidemia no período 1987-1993 nas diversas UFs, estabelecendo-se os Centros Gravimétricos (CGs relativos a esses anos. A análise do posicionamento e deslocamento pluri-anual desses CGs indica a força atrativa do Estado de São Paulo como pólo de difusão da epidemia e uma expansão simultânea da epidemia em direção às fronteiras de ocupação. Essas tendências colocam dificuldades adicionais às atividades de prevenção ao acrescentarem novos segmentos populacionais e regiões geográficas ao quadro observado inicialmente nas principais regiões metropolitanas e segmentos mais afetados.

    Full Text Available A fisiopatologia da enxaqueca ainda não foi completamente elucidada. As principais estruturas envolvidas parecem ser o sistema nervoso central (córtex e tronco cerebral, o sistema trigeminovascular e os vasos correspondentes, outras fibras autonômicas que inervam estes vasos, e os vários agentes vasoativos locais, como a SP, CGRP, NO, VIP, NPY, ACh, NA, NKA, entre outros. A depressão alastrante é o fenômeno neurológico que provavelmente justifica achados experimenais e clínicos na enxaqueca. Ela tem velocidade de propagação semelhante à aura, ativa o núcleo espinhal do trigêmeo e está relacionada à liberação de CGRP e NO. Alterações circulatórias detectadas por métodos complementares reforçam o papel da depressão alastrante. A identificação de anormalidades em pelo menos três loci (cromossomas 19 e 1 na enxaqueca hemiplégica familiar ocorreu recentemente. Elas estão relacionadas a anormalidades nos canais de cálcio voltagem dependentes tipo P/Q, específicos do sistema nervoso central, que regulam a liberação de vários neurotransmissores, incluindo possivelmente a serotonina. A exemplo de outras anormalidades neurológicas paroxísticas que resultam da hiperexcitabilidade da membrana plasmática, é possível que a enxaqueca ocorra devido a uma desordem de canais iônicos.The pathophysiology of migraine is not yet fully understood. The most important structures involved seem to be the central nervous system (cortex and brain stem, the trigeminovascular system and related cranial arteries, other autonomic fibres innervating such vessels, and various local vasoactive agents, including SP, CGRP, NO, VIP, NPY, ACh, NA, NKA, among others. The spreading depression phenomenon may explain clinical as well experimental findings in migraine. Its propagation velocity mirrors what is found in clinical aura, it may activate the spinal trigeminal nucleus and may induce CGRP and NO release. Circulatory changes detected with

    A creatinina continua a ser o padrão laboratorial para diagnóstico da injúria renal aguda (IRA). Esforços para prevenção da nefrotoxicidade foram prejudicados pelo atraso no diagnóstico da IRA por critérios utilizando somente a creatinina como marcador, havendo, por isso, grande interesse em identificar mais precocemente biomarcadores confiáveis. Além disso, o tratamento precoce da IRA pode ser correlacionado com um melhor prognóstico e a identificação de biomarcadores para um diagnóstico pre...

    Full Text Available A actinomicose mamária é doença inflamatória rara, com poucos casos descritos na literatura. Pode ser primária da mama quando resultante de traumas na pele e papila mamária, e, secundária, quando de origem toracopleural. Sua apresentação clínica é variável, devendo ser diferenciada das doenças mais comuns, dentre elas as mastites e também as neoplasias, como o carcinoma inflamatório. Seu diagnóstico é realizado pela cultura da secreção, com a identificação das colônias de Actinomyces sp. Seu tratamento é a drenagem, quando indicada, a antibioticoterapia endovenosa e manutenção oral por tempo prolongado. Os autores relatam caso de abscesso retromamário por Actinomyces sp. em gestante de 12 semanas que apresentava tumoração mamária expansiva na mama esquerda.

Sessenta e seis (79,6% eram do sexo feminino e 17 (20,4% do masculino, variando as idades de 4 a 59 anos (média 31. Trinta e sete (44,5% pacientes tinham doença biventricular, 34 (41% apenas do ventrículo direito e 12 (14,5% apresentavam EMF limitada ao ventrículo esquerdo. Todos estavam na classe funcional III ou IV da classificação da New York Heart Association. Sessenta e oito (81,9% pacientes sobreviveram à operação e foram seguidos por período de tempo que variou de um mês a 17 anos. O tempo total de seguimento foi de 6.290 pacientes/meses (média: 92 meses. Houve 15 óbitos tardios, mas em 6 a causa não esteve relacionada à doença de base. Quatro (5,8% doentes apresentaram recidiva da fibrose e foram reoperados; em 6 (8,8% apareceu fibrose no outro ventrículo. Cinco (7,3% pacientes foram reoperados, seja para retroca de prótese valvular, seja para substituir a valva preservada na primeira operação. Somente 24 (45% dos atuais 53 sobreviventes estão em classe funcional I ou II. A curva de sobrevida actuarial, incluindo a mortalidade operatória, revelou que a probabilidade de sobrevida, 17 anos após a operação, é de 55%. Conclui-se que o tratamento cirúrgico da EMF deve ser considerado um procedimento paliativo porque a operação não impede a progressão da doença. Mesmo assim a operação é recomendada em pacientes com EMF e sintomas de insuficiência cardíaca, visto ser a única forma de tratamento.Eighty-three patients with endomyocardial fibrosis (EMF underwent endocardial decortication and atrioventricular valve replacement or repair between December, 1977, and December, 1997.

  14. Autocorrelation descriptor improvements for QSAR: 2DA_Sign and 3DA_Sign.

    Science.gov (United States)

    Sliwoski, Gregory; Mendenhall, Jeffrey; Meiler, Jens

    2016-03-01

    Quantitative structure-activity relationship (QSAR) is a branch of computer aided drug discovery that relates chemical structures to biological activity. Two well established and related QSAR descriptors are two- and three-dimensional autocorrelation (2DA and 3DA). These descriptors encode the relative position of atoms or atom properties by calculating the separation between atom pairs in terms of number of bonds (2DA) or Euclidean distance (3DA). The sums of all values computed for a given small molecule are collected in a histogram. Atom properties can be added with a coefficient that is the product of atom properties for each pair. This procedure can lead to information loss when signed atom properties are considered such as partial charge. For example, the product of two positive charges is indistinguishable from the product of two equivalent negative charges. In this paper, we present variations of 2DA and 3DA called 2DA_Sign and 3DA_Sign that avoid information loss by splitting unique sign pairs into individual histograms. We evaluate these variations with models trained on nine datasets spanning a range of drug target classes. Both 2DA_Sign and 3DA_Sign significantly increase model performance across all datasets when compared with traditional 2DA and 3DA. Lastly, we find that limiting 3DA_Sign to maximum atom pair distances of 6 Å instead of 12 Å further increases model performance, suggesting that conformational flexibility may hinder performance with longer 3DA descriptors. Consistent with this finding, limiting the number of bonds in 2DA_Sign from 11 to 5 fails to improve performance. PMID:26721261

    1971-03-01

    Full Text Available A cisticercose, um dos mais sérios problemas parasitológicos do sistema nervoso, apresenta, quando localizada na fossa posterior, um quadro clínico dramático, no qual predomina a hipertensão intracraniana. Foram estudados neste trabalho, 70 pacientes com cisticercose de fossa craniana posterior, atendidos no Serviço de Neurocirurgia do Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo de 1945 a 1968. Considerando-se a grande diversidade existente em torno das técnicas de tratamento cirúrgico, foi objetivo deste trabalho o estudo dos resultados obtidos nestes pacientes, nos quais várias técnicas foram empregadas. As cirurgias paliativas que derivam o trânsito do líquido cefalorraqueano para regiões extracranianas, quando comparadas aos outros tipos de cirurgias utilizados, foram as que proporcionaram maior índice de recuperação, exigiram menos reoperações, além de terem sido acompanhadas de menor número de complicações, bem como de menor mortalidade pós-operatória. Por outro lado, a neurocisticercose geralmente é um processo difuso, encontrando-se parasitas em várias regiões do encéfalo e/ou aracnoidite, conforme comprovou-se, também, entre os casos ora reunidos e que vieram a falecer. Baseando-se nestes fatos, não se justificam as derivações intracranianas e, a não ser eventualmente, a abordagem direta do parasita. Os casos estudados permitem cone- tatar, portanto, que as derivações extracranianas, por sua simplicidade e eficácia, apresentam-se, atualmente, como a terapêutica cirúrgica mais propriada à cisticercose de fossa craniana posterior.

  8. Fenomenologia e crise da arquitetura

    2005-12-01

    Full Text Available Ao se fazer no espaço limítrofe entre a engenharia e a arte, a arquitetura enfrenta simultaneamente problemas estéticos e técnicos. Esta situação a torna tarefa sempre inacabada, ciência tecida no diálogo constante entre dois valores e fazeres tradicionalmente antagônicos. Diante desse quadro, busca-se comumente enraizar a arquitetura em fundamentos exteriores aos seus próprios conceitos, seja na improvisação criadora dos indivíduos, inerente à vida urbana, ou nos diversos saberes sobre o homem que equacionam as necessidades universais às quais ela deveria responder. Estas considerações preliminares conduzem ao cerne de uma questão propriamente filosófica acerca dos fundamentos pré-reflexivos do mundo da vida (Lebenswelt e, no caso da arquitetura, sobre a experiência do habitar que constitui o campo ontológico "regional" de onde parte a ciência/arte aqui investigada.Architecture faces technical and aesthetical problems since it exists in the space between Engineering and Art. This situation turns Architecture into an endless task, a science made in a ceaseless dialogue between two traditional antagonistic values. Art and Engeneering seek to base Architecture in foundations that are outside its own concepts, either when they try to base it in creative improvisation of individuals in their urban lives or when they try to put its roots in several different cognizances about humankind to which it should respond. This introductory essay intends to take us to the experience of inhabitation which constitutes the ontological "region" where this science/art departs from.

  9. SOBRE AS ORIGENS DA FAVELA

    Directory of Open Access Journals (Sweden)

    Alfredo Pereira de Queiroz Filho

    2011-01-01

    Full Text Available This paper focuses upon the origins of the Brazilian shantytown (favela. It investigates the context of the appearance of the housing and of the name itself which came to characterize this form of precarious settlement in Rio de Janeiro at the end of the 19th century. Evidence suggests that the appearance of the shacks was related to the population explosion and the lack of housing in what was the Federal Capital at the time. The name ¿favela¿ is considered to have its origins in the place name 'Alto da Favela', a district on high ground located to the south of the town of Belo Monte, in the North-eastern state of Bahia, which was the site of the 'War of Canudos' uprising. 'Favela' is also the popular name for a plant, common to the outback of Bahia where the fi ghting took place. The species described by Euclides da Cunha, in his book 'Os Sertões', is probably the Cninodoscolus quercifolius. Of the many theories concerning the renaming of the hill district 'Providência' as 'Favela' by those who had been involved in the uprising, the most plausible is that it recalls strategic and topographic features. On the 'Favela' hill in Canudos, the Republican troops were ambushed, and the occupation was extremely important in the defeat of Antonio Conselheiro's followers. The topography is associated with a metaphor for the deprivation suffered by the troops during and after the fi ghting. The natural diffi culties of the battle, compounded by the physical characteristics of the outback, were related to the struggle the soldiers had in receiving their pay once the war had ended.

    For wells which are part of a battery for public water supply in Juazeiro do Norte, in the south of Ceara State we made mathematical simulation, using MODFLOW, of the pumping tests performed during the period of drilling. These wells supposedly explore the Rio da Batateira aquifer. However, satisfactory modeling is possible only when admitting a strong contribution of the inferior aquifer, which is Missao Velha. The existence of leaks between the aquifers and their location could be also proved through the geologic profiles, measurements of C-14, O-18 and electric conductivity. This way, we proved that the battery Riacho dos Macacos in Juazeiro do Norte produces a mixture of two components; an old one, with low pMc and {delta}{sup 18} O and high electric conductivity, originating from the Missao Velha aquifer and a young component from the Rio da Batateira aquifer, characterized by high pMC and {delta}{sup 18} O and low electric conductivity.

    O sector avícola enfrenta atualmente dois desafios muito estimulantes. O primeiro decorre do aumento, que se prevê continuar a crescer, nos níveis de procura de carne de aves no mercado interno e internacional; o segundo decorre do facto da criação avícola ter adotado métodos de produção mais intensivos (kg peso vivo/m2/ano) e em maior escala, i.e. com maior concentração animal na mesma exploração. Este carácter vincadamente “industrial” tem merecido uma natural atenção das sociedades e das a...

  13. Da veritas à caritas: a religião depois da religião

    Directory of Open Access Journals (Sweden)

    Márcio Antônio de Paiva

    2015-04-01

    Full Text Available Este artigo visa abordar a passagem da veritas para a caritas, como possibilidade privilegiada da espiritualidade após a religião. No horizonte da filosofia da religião, o artigo discute os problemas de tal perspectiva e aponta sua contribuição para ler o fenômeno da espiritualidade dos sem religião. Tal objetivo será direcionado para o retorno da religião segundo o senso cultural comum, de um lado; e de outro, para a queda das razões filosóficas do ateísmo. Percorrendo as obras consideradas fundamentais, o texto se desenvolve a partir do horizonte maior do pensiero debole, mostrando a perspectiva hermenêutica da verdade – a verdade como abertura – até desembocar na concepção de caritas, como viés possível da experiência religiosa, após a morte de Deus e o fim da metafísica. Vattimo vê na passagem da veritas à caritas o itinerário do pensamento contemporâneo, definindo o cristianismo como ato de amor antes que revelação de verdades.

  14. ESTATUTO PARADOXAL DA PELE E CULTURA CONTEMPORÂNEA: da porosidade à pele-teflon

    Maria Cristina Franco Ferraz

    2014-06-01

    Full Text Available A exploração do estatuto paradoxal da pele - interface dentro/fora - permite ultrapassar a dicotomia metafísica superfície/profundidade, problematizando a tendência atual, também expressa na teoria, a um elogio das superfícies e a um horror por oposições dicotômicas. Possibilta avaliar as implicações do fechamento da porosidade da pele em formas de sociabilidade estimuladas na cultura da imagem, da exibição, do espetáculo, bem expressas pelo material inorgânico teflon. Sendo Poros, na visão grega, pai de Eros, a investigação acerca do estatuto paradoxal da pele convida a uma retomada do tema do erotismo. Partindo de perspectivas oferecidas por Agamben acerca da pornografia, ligada ao valor de exibição nas sociedades de espetáculo e de consumo, e relacionando-as a diversas reflexões de José Gil acerca do corpo e da pele, discute-se e convoca-se a abertura da porosidade da pele.

    Full Text Available Os inventários objetivos de autorrelato têm sido amplamente utilizados nas últimas décadas. Padrões de resposta enviesados dão espaço à simulação, se constituindo como um importante problema desses instrumentos. O MCMI-III é um instrumento para avaliação da personalidade amplamente utilizado no mundo, em diversos contextos onde a simulação pode estar presente. Assim, o presente trabalho objetiva investigar as escalas Desejabilidade Social e Valorização negativa do instrumento, colaborando para a adaptação do MCMI-III para o Brasil. Os participantes (n = 2570 são originários de todo o país, com faixa etária e de escolaridade diversas. Após resposta ao instrumento, foram categorizados de acordo com sua pontuação nas escalas supracitadas nos grupos Baixo, Médio e Alto para comparação estatística através de Analise Univariada. Foram encontradas diferenças entre os grupos, com maiores médias clínicas para os grupos de maior Valorização Negativa e menor Desejabilidade Social, indicando indícios de validade de constructo das escalas estudadas. Self-report inventories have been widely used since last decades. Malingering by response bias are an important matter about such psychological tests. The MCMI-III is a personality assessment inventory that has been widely used in the world, including when malingering is highly suspected. So, this article aims to investigate Desirability and Debasement Scales of MCMI-III, thus contributing to the test adaptation for Brazil. Study sample (n = 2570 comes from the whole country, and has a large spectrum of age and education. After administration of the test, participants were categorized according to scores obtained in Low, Medium and High groups, to comparison by One-way ANOVA. Statistical differences has been found among groups, and highest clinical scores found was that from high Debasement and low Desirability groups, signing to construct validity of scales.

    Full Text Available Combatente do gueto, guerreiro da periferia, militante da causa (... Combatente do gueto é o nome de uma rua atrás do Palácio do Governo (...” conta Jairo, taxista, a propósito de sua inspiração poética, durante as filmagens de Povo lindo, povo inteligente – O Sarau da Cooperifa, documentário dirigido por Sérgio Gagliardi e Maurício Falcão, produzido, em 2008, pela DGT Filmes. O filme narra a história e os bastidores do sarau que acontece na zona sul da cidade de São Paulo, em Campo Limpo, no bar do Zé Batidão. “A periferia não tem museu, não tem teatro nem cinema, o único espaço público que tem é o bar”, explica Sérgio Vaz, um dos idealizadores do movimento que contempla na produção poética, da periferia para a periferia, a força da contestação social. A cultura como arena para a luta entre os signos monossêmicos e a pluralidade sígnica proposta pelo artista que faz da palavra ruído incômodo. O sarau da Cooperifa, o sarau do Binho também já foram objetos de estudos acadêmicos, como a tese As redes de escritura nas periferias de São Paulo, de Marco Antônio Bin, defendida no Programa de Ciências Sociais da PUCSP, em maio de 2009
