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.

Fractures and dislocations of the hand are some of the most frequently encountered injuries of the musculoskeletal system traumas. To evaluate these lesions radiography is the investigation of choice, and is rarely needed the help of other images to establish the diagnosis and treatment. The image quality of the X-ray examination is therefore essential. In this study a homogeneous phantom hand was developed for use in the hand image optimization process. In this procedure were quantified for different tissue thicknesses which are an anthropomorphic hand phantom. To perform the classification and quantification of tissue was applied membership functions in histograms of CT scans. The same procedure was adopted for 30 retrospective examinations of patients in the Hospital of the Faculty of Medicine of Botucatu UNESP (HCFMB-UNESP). The homogeneous phantom built was used to calibrate the techniques used in clinical routine (RC). Such calibrated techniques were used to acquire images of anthropomorphic phantom. These images were analyzed by Visual Grading Method (VFA) by experienced radiologists in the area. The image with better grade in AGV and lower dose was chosen as the Gold Standard. The results showed concordance between the tissue thicknesses which constitute the anthropomorphic phantom and the sample evaluated patients, with variations between 12.63% and 6.48% for soft tissue and bone, respectively. The Gold Technical Standard compared with the technique normally used in the CR reduces dose charge 41.28% and 33.18% in the tube.

The nuclear fuel reload optimization is a NP-Complete combinatorial optimization problem. For decades this problem was solved using an expert's knowledge. From the eighties, however there have been efforts to automatic fuel reload and the more recent ones show the Genetic Algorithm's (GA) efficiency on this problem. Following this trend, our aim is to optimization nuclear fuel reload using Ant-Q, artificial theory based algorithms. Ant-Q's results on the Traveling salesman Problem, which is conceptuality similar to fuel reload, are better than GA's. Ant-Q was tested in real application on the cycle 7 reload of Angra I. Comparing Ant-Q result with the GA's, it can be verified that, even without a local heuristics, the former algorithm, as it superiority comparing the GA in Angra I show. Is a valid technique to solve the nuclear fuel reload problem. (author)

The mathematical modeling of Transfer and Storage Systems (TE) has been an important tool in support the decision making, for, due to the large number of its interfaces and the complexity of its interactions, many times it's difficult to predict all possible consequences of factors affecting the area (Revamps, new units, maintenance, market, etc.) and without the support of a consistent mathematical model, intuition some times leads to erroneous conclusions. The application of simulation techniques to models enables a wider use, for through the utilization of probabilistic models representing interfaces (market, supply, production, laboratory, etc.) it is possible to simulate logistic costs and service level in different scenarios, subsidizing technical and managerial decisions leading to optimization of inventories. Major advantages are: once it is created, a model can be used several times to assess the proposed projects and policies; the analysis methodology used by simulation enables the assessment of a proposed system, even if the entry data are still under form of schemes or drafts; simulation is generally easier to be applied than analytical methods. A partnership was created among several of PETROBRAS' managers for the development of the so-called 'Integral and Integrated Model of Transfer and Storage' or 'M2TE'. Examples of application of such model to some refineries and the relevant results obtained are reported below. (author)

The present work offers a decision supporting system, integrated in different techniques (genetic algorithms, cultural algorithms, co-evolution, neural networks, neuro fuzzy model and distributed processing) for optimization of exploitation of oil reservoirs. The EXPLOT system identifies exploitation alternatives and determines the quantity, position, type (producers or injectors) and structure (horizontal or vertical) of wells, that maximize the present net value of the alternative (VPL). The EXPLOT system is composed of three main modules: the optimizer (genetic algorithms, cultural algorithms and co-evolution), the Production Curves Obtention (approximator neuro fuzzy-NFHB of the production curve) and the present net value calculation. To estimate the VPL of each developmental alternative, the system utilizes a reservoir simulator, specifically the IMEX, although other simulators may be utilized. In addition to these technologies, the system also utilizes distributed processing, based on the CORBA architecture for distributed execution of the reservoir simulator in a computer network, which significantly reduces the total optimization time. The EXPLOT system was already tested in different examples of oil fields. Results obtained so far are considered consistent according to the opinion of specialists, who consider the system as a new decision support tool concept in the area. The differences of EXPLOT are not only to be found in its efficient optimization model, but also in its interface, through which the specialists interact with the system, introducing project recommendations (e.g., five-spot wells), commanding a localized search for best solutions, sizing the simulation network and monitoring simulation distribution by means of available networks. The EXPLOT system is the result of joint research between CENPES and the Applied Computational Intelligence Lab, PUC-Rio, accomplished during the past three years. The continuation of this research project expands

This work suggests a Pre-analysis in the input parameters of an optimization system (Bonacin et al., 2007; Boschetto et al., 2008). The proposed method is based on programming techniques that use lists of objects threaded, where objects are elements belonging to the same class, according to the concept of the object-oriented programming. The Preanalysis makes a previous evaluation of a batch sequencing, getting information to be entered into an optimization block. The continuous time Mixed Integer Linear Programming (MILP) model gets such information and determines the scheduling. The models are applied on a pipeline network that connects different areas including refineries, terminals, and final clients. Many oil derivatives (e.g. gasoline, liquefied petroleum gas, naphtha) can be sent or received in this network. The Pre-analysis objective is to reduce the computational time of an MILP model, and the proposed approach can aid the decision-making process to obtain a more detailed scheduling. (author)

There are two procedures for the distribution of centralizers on casing: rules of thumb for vertical wells and the well-know theoretical model developed in API SPEC 10D. This paper presents a new approach for the disposition of centralizers. Casing deflection is modeled more realistically than in the API algorithm, using better boundary conditions. A computer application was developed to integrate information on hole trajectory, casing properties and the performance of centralizers, in order to optimize centralizer spacing. The paper also presents a few comparative examples, and the results obtained are less conservative than those of the API model, thus reducing the number of centralizers to be run in a particular well.

The optimization concept in radiation protection is, in its essence, practical. In each aspect that we deal with the man, it is necessary to take frequent decisions such as: what is the protection level to be pursued, since the protection levels under consideration provide doses lower than the appropriate annual limits. The optimization gives a basic framework of the minding that is appropriate to conduct to a balance kind of the resources available for the protection and protection level obtained against a multitude of factors and constrains in a manner to obtain the best result. In this work, was performed the optimization, from the radiation protection point of view, of a facility project who enclose two shielded hot cells where will be handled UO{sub 2} small plate with 50% of U-235 burn-up, irradiated in the research swimming pool reactor, IEA-R1. To obtain this goal were specified the relevant factors and criteria, were applied the main techniques used in a decision-making in radiological protection, presently adopted and was performed a sensibility study of the factors and criteria used in this work. In order to obtain a greater agility in applying the techniques for decision-making was developed a micro computer program. (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)

The work aims to optimize and improve the efficiency of the internal monitoring technique developed at Centro Regional de Ciencias Nucleares do Nordeste for F-18 in form of F-18DG radiopharmaceuticals. It was performed two assays for the methodology developed. The first was performed in a makeshift room, while the second was performed in a room with walls reinforced with concrete. The detection system was a NaI (Tl) 3{sup x} 3{sup s}cintillation detector, coupled with the software Genie 2000. In order to obtain the calibration factor, a brain phantom containing {sup 22}Na liquid source was measured. The interpretation of the bioassay data was performed using the biokinetic models provided by the ICRP 53 and edited by software AIDE-version 6, which gives the fraction of activity retained in the organs as a function of time. The sensitivities of detection were similar, resulting in a minimum detectable dose below 1 mSv, as recommended by the IAEA. (author)

Robotic-assisted laparoscopic nephroureterectomy (RALNU) has been previously utilized for management of upper tract urothelial carcinoma. The da Vinci Xi surgical system was released in April of 2014. We describe our operative technique and early experience for RALNU using the da Vinci Xi system highlighting unique features of this surgical platform. A total of 10 patients with a diagnosis of upper tract urothelial carcinoma underwent RALNU using the da Vinci Xi system between April and November of 2014. A novel, oblique "in line" robotic trocar configuration was utilized to access the upper abdomen (nephrectomy portion) and pelvis (bladder cuff excision) without undocking. The port hopping feature of da Vinci Xi was utilized to facilitate optimal, multi-quadrant visualization during RALNU. Robotic-assisted laparoscopic nephroureterectomy was successfully completed without open conversion in all 10 patients. Mean operative time was 184 min (range 140-300 min), mean estimated blood loss was 121 cc (range 60-300 cc), and mean hospital stay was 2.4 days. Final pathology demonstrated high grade urothelial carcinoma in all patients. Surgical margins were negative in all patients. No intra-operative complications were encountered. One patient developed a pulmonary embolus after being discharged. No patients required a blood transfusion. Mean patient follow-up was 130 days (range 15-210 days). The use of da Vinci Xi with a novel, oblique "in line" port configuration and camera port hopping technique allows for an efficient and reproducible method for RALNU without the need for repositioning the patient or the robot during surgery.

Robot-assisted laparoscopic surgery is often taught with the surgical mentor at the surgeon console and the trainee at the patient's bedside. The da Vinci dual console (Intuitive Surgical, Sunnyvale, California) allows a surgical mentor to teach with both the mentor and the trainee working at a surgeon console simultaneously. The purpose of this study is to evaluate the effectiveness of the dual console versus the single console for teaching medical students robotic tasks. Forty novice medical students were randomized to either the da Vinci single-console or dual-console group and were taught 4 knot-tying techniques by a surgical mentor. The students were timed while performing the tasks. No statistically significant differences in mean task times were observed between the single- and dual-console groups: interrupted stitch with a 2-handed knot (300 seconds for single vs 294 seconds for dual, P=.59), interrupted stitch with a 1-handed knot (198 seconds for single vs 212 seconds for dual, P=.88), figure-of-8 stitch with a 2-handed knot (261 seconds for single vs 219 seconds for dual, P=.20), and figure-of-8 stitch with a 1-handed knot (200 seconds for single vs 199 seconds for dual, P=.53). No significant difference was observed in performance time when teaching knot-tying techniques to medical students using the da Vinci dual console compared with the single console. More research needs to be performed on the utility of the da Vinci dual console in surgical training.

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)

The objective of this work is to optimize the extractions of the low-pressure turbine of a PWR nuclear reactor, in order to obtain the best thermodynamic cycle efficiency. We have analyzed typical data of a 1300 MW PWR reactor, operating at 25%, 50%, 75% and 100% capacities, respectively. The first stage of this study consists of generating a mathematical model capable of describing the reactor behavior and efficiency at any power level. The second stage of this study consists of to combine the generated mathematical model in an optimization computer program that optimize the extractions flow of the low-pressure turbine until it finds the optimal system efficiency. This work does not alter the nuclear facility project in any way. (author)

Full Text Available Many techniques have been proposed for surgical training as a learning process for young surgeons or for the simulation of complex procedures. Stereolithograpfy, a rapid prototyping technique, has been presented recently as an option for these purposes. We describe the case of a 12 years old boy, diagnosed with Ewing´s sarcoma in the cervical spine. After a surgical simulation accomplished in the prototype, built by stereolithography, the patient was submitted to a C4 corpectomy and to a C4 and C3 laminectomy with anterior and posterior fixation, a non intercurrence procedure. This technique is an innovative and complementary tool in diagnosis and therapy. As a result, it is easier for the surgeon to understand the complexity of the case and plan the approach before any surgical procedure.Lesões tumorais da coluna podem representar um grande desafio para equipe cirúrgica. A estereolitografia é uma técnica de construção de peças anatômicas a partir de desenhos gráficos ou exames radiológicos. Apresentamos um paciente de 12 anos, com quadro de cervicobraquialgia à direita com diagnóstico de sarcoma de Ewing. Ao exame neurológico, o paciente apresentava-se com paresia em MSD grau IV e leve hipoestesia em dermátomos de C6 à T1 à direita. RM evidenciou edema intra e extra-ósseo com compressão medular e instabilidade cervical. Realizada simulação cirúrgica no protótipo construído por estereolitografia. Foi submetido a corpectomia de C4 e a laminectomia C4 e C3, com fixação anterior e posterior, procedimento sem intercorrências. A estereolitografia é ferramenta inovadora no auxílio diagnóstico e terapêutico. Seu uso permite ao cirurgião entender fisicamente o sítio da lesão, estudar a via de acesso e perceber a real complexidade do caso antes do procedimento cirúrgico.

Soil contamination is today one of the most important environmental issues for society. In the past, soil pollution was not considered as important as air and water contamination, because this was more difficult to be controlled, becoming an important topic in studies of environmental protection worldwide. Based on this, this paper provides information on the determination of metals in soil samples collected in Zona da Mata, Pernambuco, Brazil, where normally the application of pesticides, insecticides and other agricultural additives are used in a disorderly manner and without control. A total of 24 sampling points were monitored. The analysis of Mn, Fe, Ni, Zn, Br, Rb, Sr, Pb, Ti, La, Al, Si and P were performed using Energy Dispersive X-Ray Fluorescence. In order to assess the development of analytical method, inorganic Certified Reference Materials (IAEA-SOIL-7 and SRM 2709) were analyzed. In each sampling site, the geoaccumulation index were calculated to estimate the level of metal contamination in the soil, this was made taking into account the resolution 460 of the National Environmental Council (CONAMA in Portuguese). The elemental distribution patterns obtained for each metal were associated with different pollution sources. This assessment provides an initial description of pollution levels presented by metals in soils from several areas of Zona da Mata, providing quantitative evidence and demonstrating the need to improve the regulation of agricultural and industrial activities.

2017-06-01

The da Vinci Xi robot has been introduced as the successor to the Si platform. The promise of the Xi is to open the door to new surgical procedures. For robotic-assisted radical prostatectomy (RARP)/pelvic surgery, the potential is better vision and longer instruments. How has the Xi impacted on operative and pathological parameters as indicators of surgical performance? This is a comparison of an initial series of 42 RARPs with the Xi system in 2015 with a series using the Si system immediately before Xi uptake in the same calendar year, and an Si series by the same surgeon synchronously as the Xi series using operative time, blood loss, and positive margins as surrogates of surgical performance. Subjectively and objectively, there is a learning curve to Xi uptake in longer operative times but no impact on T2 positive margins which are the most reflective single measure of RARP outcomes. Subjectively, the vision of the Xi is inferior to the Si system, and the integrated diathermy system and automated setup are quirky. All require experience to overcome. There is a learning curve to progress from the Si to Xi da Vinci surgical platforms, but this does not negatively impact the outcome.

Three instrumental techniques, headspace-mass spectrometry (HS-MS), mid-infrared spectroscopy (MIR) and UV-visible spectrophotometry (UV-vis), have been combined to classify virgin olive oil samples based on the presence or absence of sensory defects. The reference sensory values were provided by an official taste panel. Different data fusion strategies were studied to improve the discrimination capability compared to using each instrumental technique individually. A general model was applied to discriminate high-quality non-defective olive oils (extra-virgin) and the lowest-quality olive oils considered non-edible (lampante). A specific identification of key off-flavours, such as musty, winey, fusty and rancid, was also studied. The data fusion of the three techniques improved the classification results in most of the cases. Low-level data fusion was the best strategy to discriminate musty, winey and fusty defects, using HS-MS, MIR and UV-vis, and the rancid defect using only HS-MS and MIR. The mid-level data fusion approach using partial least squares-discriminant analysis (PLS-DA) scores was found to be the best strategy for defective vs non-defective and edible vs non-edible oil discrimination. However, the data fusion did not sufficiently improve the results obtained by a single technique (HS-MS) to classify non-defective classes. These results indicate that instrumental data fusion can be useful for the identification of sensory defects in virgin olive oils. Copyright © 2016 Elsevier Ltd. All rights reserved.

3D measurement and modelling have been traditionally applied to statues, buildings, archeological sites or similar large structures, but rarely to paintings. Recently, however, 3D measurements have been performed successfully also on easel paintings, allowing to detect and document the painting's surface. We used 3D models to integrate the results of various 2D imaging techniques on a common reference frame. These applications show how the 3D shape information, complemented with 2D colour maps as well as with other types of sensory data, provide the most interesting information. The 3D data acquisition was carried out by means of two devices: a high-resolution laser micro-profilometer, composed of a commercial distance meter mounted on a scanning device, and a laser-line scanner. The 2D data acquisitions were carried out using a scanning device for simultaneous RGB colour imaging and IR reflectography, and a UV fluorescence multispectral image acquisition system. We present here the results of the techniques described, applied to the analysis of an important painting of the Italian Reinassance: `Madonna dei Fusi', attributed to Leonardo da Vinci.

To describe our robot-assisted nephroureterectomy (RNU) technique for benign indications and RNU with en bloc excision of bladder cuff (BCE) and lymphadenectomy (LND) for malignant indications using the da Vinci Si and da Vinci Xi robotic platform, with its pros and cons. The port placement described for Si can be used for standard and S robotic systems. This is the first report in the literature on the use of the da Vinci Xi robotic platform for RNU. After a substantial experience of RNU using different da Vinci robots from the standard to the Si platform in a single-docking fashion for benign and malignant conditions, we started using the newly released da Vinci Xi robot since 2014. The most important differences are in port placement and effective use of the features of da Vinci Xi robot while performing simultaneous upper and lower tract surgery. Patient positioning, port placement, step-by-step technique of single docking RNU-LND-BCE using the da Vinci Si and da Vinci Xi robot are shown in an accompanying video with the goal that centres using either robotic system benefit from the hints and tips. The first segment of video describes RNU-LND-BCE using the da Vinci Si followed by the da Vinci Xi to highlight differences. There was no need for patient repositioning or robot re-docking with the new da Vinci Xi robotic platform. We have experience of using different robotic systems for single docking RNU in 70 cases for benign (15) and malignant (55) conditions. The da Vinci Xi robotic platform helps operating room personnel in its easy movement, allows easier patient side-docking with the help of its boom feature, in addition to easy and swift movements of the robotic arms. The patient clearance feature can be used to avoid collision with the robotic arms or the patient's body. In patients with challenging body habitus and in situations where bladder cuff management is difficult, modifications can be made through reassigning the camera to a different port with

The computed radiography (CR) has become the most used device for image acquisition, since its introduction in the 80s. The detection and early diagnosis, obtained through CR examinations, are important for the successful treatment of diseases of the hand. However, the norms used for optimization of these images are based on international protocols. Therefore, it is necessary to determine letters of radiographic techniques for CR system, which provides a safe medical diagnosis, with doses as low as reasonably achievable. The objective of this work is to develop an extremity homogeneous phantom to be used in the calibration process of radiographic techniques. In the construction process of the simulator, it has been developed a tissues' algorithm quantifier using Matlab®. In this process the average thickness was quantified from bone and soft tissues in the region of the hand of an anthropomorphic simulator as well as the simulators' material thickness corresponding (aluminum and Lucite) using technique of mask application and removal Gaussian histogram corresponding to tissues of interest. The homogeneous phantom was used to calibrate the x-ray beam. The techniques were implemented in a calibrated hand anthropomorphic phantom. The images were evaluated by specialists in radiology by the method of VGA. Skin entrance surface doses were estimated (SED) corresponding to each technique obtained with their respective tube charge. The thicknesses of simulators materials that constitute the homogeneous phantom determined in this study were 19.01 mm of acrylic and 0.81 mm of aluminum. A better picture quality with doses as low as reasonably achievable decreased dose and tube charge around 53.35% and 37.78% respectively, compared normally used by radiology diagnostic routine clinical of HCFMB-UNESP.

Full Text Available O Vírus da leucemia felina (FeLV pertence à família Retroviridae, gênero Gammaretrovirus. Diferentemente de outras retroviroses, uma parcela dos gatos jovens e adultos exposta ao FeLV não apresenta antigenemia/viremia, de acordo com as técnicas convencionais de detecção viral, como isolamento em cultivo celular, imunofluorescência direta e ELISA. O emprego de técnicas de maior sensibilidade para detecção e quantificação viral, como o PCR quantitativo, permitiu a identificação de animais positivos para a presença de DNA proviral e RNA na ausência de antigenemia/viremia e, com isso, um refinamento da análise das diferentes evoluções da infecção. Assim, reclassificou-se a patogenia do FeLV em 4 categorias: infecção abortiva, regressiva, latente e progressiva. Foi possível também detectar DNA proviral e RNA em animais considerados imunes ao FeLV após vacinação. Diante disso, os objetivos desta revisão de literatura foram demonstrar as implicações da utilização de técnicas sensíveis de detecção viral na interpretação e classificação da infecção do FeLV e rever as técnicas de detecção do vírus para fins de diagnóstico. Além disso, apresentar os resultados referentes à eficácia da vacinação contra o FeLV com a utilização dessas técnicas.Feline leukemia virus (FeLV belongs to the Retroviridae family, genus Gammaretrovirus.

The use of more sensitive techniques to detect and quantify viruses enabled the detection of proviral DNA and RNA in cats with undetectable antigenemia/viremia, and thus the refinement of the different infection outcomes analysis. As a result, FeLV pathogenesis was reclassified in 4 categories: abortive, regressive, latent and progressive infections. It

Multiphase ASL is an effective way to overcome the regional variation of the transit time that difficult the estimation of perfusion values. However, with conventional multiple phases ASL techniques, the ASL contrast at later phases is impaired due to repeated application of excitation pulses and longitudinal relaxation making it difficult to evaluate the tissue perfusion in regions where the transit time is longer. In the present study, we show an improvement of the acquisition scheme by exploring a modulation on the flip angle of the MR acquisition to keep the ASL contrast constant over multiple phases.

The oil industry has been investing in research and development of new techniques and process improvements with the objective to increase the residual fraction profitability and to fulfill the market demands. The adequacy of the refining scheme has led to the development of bottom of the barrel processes that has the objective to convert heavy fractions into products of higher aggregate value. In this context, the process of Delayed Coking presents a great importance in the production of distillates in the diesel range as well as the processing of heavy residues, mostly in the markets where the fuel oil consumption is being reduced. With the approach to help PETROBRAS decide which route to follow during new designs of Delayed Coking units, this work presents a comparative study of the preheat train performance among the energy recovery to preheat the feed, in contrast with preheating the feed and generating steam, simultaneously. In this study the Pinch Technology methodology was used as a procedure for heat integration with the objective of getting the maximum energy recovery from the process, finding the best trade-off between operational cost and investment cost. The alternative of steam generation aims to provide an appropriate flexibility in Delayed Coking units design and operation. (author)

Para tanto, utilizamos como ferramenta de análise a notação de movimentos coreográficos criada por Rudolf von Laban; este sistema é aplicado aos gestos requeridos para se realizarem cinco passagens da obra de Kampela onde os efeitos de percussão estão particularmente presentes. A partir da leitura dos cinetogramas criados, podemos observar uma predominância de movimentos em ricochete e outros efeitos percussivos que, além de promover um melhor relaxamento muscular, corroboram no impacto visual que a peça causa por sua gestualidade corporal. Observamos também que há uma notável exploração espacial do instrumento. Ao abordarmos o fazer musical de um ponto de vista coreográfico, entendemos este como um complexo que inclui o som produzido, os gestos e movimentos do performer, sua energia, seu corpo e o espaço que o circunda.

Digital mammography is replacing screen-film mammography due to several advantages of digital receptors. The use of Computed Radiography (CR) mammography systems has been considered an alternative to achieve digital images with a low cost. Besides, the optimization of the X-ray spectrum, characterized by the anode/filter combination and tube potential, is an important step in order to improve the image quality with the lower dose to the breast. In this work, we investigated the optimal X-ray spectra using a figure of merit for two mammography equipment: Senographe DMR (General Electric Medical Systems) and Mammomat 3000 Nova (Siemens), both using an image plate Kodak EHR-M2 (Kodak DirectView). A PMMA phantom, simulating breast with thicknesses of 5 cm, was used. The anode/filter combinations evaluated were: Mo/Mo, Mo/Rh, Rh/Rh and Rh/Al for the Senographe system, and Mo/Mo, Mo/Rh, W/Rh for the Mammomat system, for all the intervals of tube potential range from 24 to 35 kVp. Results demonstrate that the higher values of FOM were achieved with the Rh/Rh at 29 kVp and Rh/Al at 26 kVp for the Senographe system, and for the W/Rh at 28 kVp in the Mammomat one. The reduction in the dose associated with the optimum spectra was 13 and 26% for the Senographe and Mammomat systems, respectively. Finally, our results suggest that anode/filter combinations of more energetic spectra than the standard Mo/Mo combination are recommended for thicker breast, in order to reduce the breast dose levels.

For a performance preview of a drilling system is necessary a dynamic and integrated modeling for understanding all system forces resulting from the combination of the rock strength, cut structure action, drilling parameters, BHA and all others drilling components. This study must predict, for the drill string, vibrations and torsions, from bit to surface, its origins and its effects, and provides the best way to reduce these vibrations, determining the best bit, BHA and drilling parameters. Thereby, this study eliminates the trial and error approach and the operation risks. This paper aims to present studies of optimization for two drilling wells conducted in Brazil, one in Santos Basin and other in Campos Basin, and compares the numerical simulations results with the data from drilling operations.

The signal to noise ratio (S/N) of radiographic film images may be optimized if the thicknesses and atomic composition of the structures to be analyzed are known. With specifications and a knowledge of the interaction of photons with the materials, the photon energy for maximum contrast may be determined. We propose a K-edge filter in addition to the normal aluminum filter, to reduce the dose to the patient by the transmission of a narrow spectrum of photons with energies to optimize the image contrast. The optimum photon energy to obtain the best contrast between dental pulp and dentine and between dentine and dental enamel was determined to be 29-34 and 22-26 keV respectively. The filter material, which closely approximates these spectra, is made of Ce (Z=58) whose thickness is shown do depend on the parameters of the X-ray generator. (author)

An oil ship when discharge its load, pumps water of the sea for its ballast tanks. This water has the function of maintaining balance, stability and the structural integrity, especially when the oil tank is empty of cargo. Thus, organisms and sediments presents in the water are pumped for the interior of the ballast tanks, being transferred from its natural habitat to another one. This may cause serious ecological unbalances. Hydrocyclone are very efficient and, as they produce high capacities, they seem to be appropriated for ballast water treatment. In this work, computational fluid dynamics (CFD) was used to optimize the geometry of a hydrocyclone, aiming to maximize the separation of the suspended solids present in seawater. A oil ship of 150,000 tons of gross cargo was used as a model. This ship has a ballast capacity of 45,000 m{sup 3} and requires 10 h for filling its ballast tanks. To ballast this ship it would be necessary a battery of 795 hydrocyclones in parallel, having each hydrocyclone a diameter of 8,5 cm. The simulation produced an total efficiency of 99% when treating suspended solids with sizes ranging from 10 to 2500 {mu}m, with a 1.06 g cm-3 density. (author)

The main purpose of this work is the definition of operational conditions for the steam and power conservation of Pressurized Water Reactor (PWR) plant in order to increase its system thermal efficiency without changing any component, based on the optimization of operational parameters of the plant. The thermal efficiency is calculated by a thermal balance program, based on conservation equations for homogeneous modeling. The circuit coefficients are estimated by an optimization tool, allowing a more realistic thermal balance for the plans under analysis, as well as others parameters necessary to some component models. With the operational parameter optimization, it is possible to get a level of thermal efficiency that increase capital gain, due to a better relationship between the electricity production and the amount of fuel used, without any need to change components plant.

This study focuses on the methodology for optimization to obtain nanocellulose from vegetal fibers. An experimental planning was carried out for the treatment of curaua fibers and parameters were estimated, having the concentration of H{sub 2}SO{sub 4}, hydrolysis time, reaction temperature and time of sonication applied as independent variables for further statistical analysis. According to the estimated parameters, the statistically significant effects were determined for the process of obtaining nanocellulose. According to the results obtained from the thermogravimetric analysis (TGA) it was observed that certain conditions led to cellulose with degradation temperatures near or even above that of untreated cellulose fibers. The crystallinity index (IC) obtained after fiber treatment (X-ray diffraction) were higher than that of the pure fiber. Treatments with high acid concentrations led to higher IC. (author)

This works has arisen from the need of updating radiological protection procedures, creating new ones and training qualified personnel to perform radiological protection duties in a nuclear facility. The main purpose of the research was to assess and minimize gamma and neutron dose rates emitted during the production and handling of radiopharmaceuticals at IEN/DIRA. A mobile measurements system (SMMG-N) was developed for on-site measurements. This system has proven to be more handy than the equipment formerly used for for this task. It has also proven to reduce the measurements uncertainties and to allow for the standardization of assessment procedures. He dose rates calculated using the data provided by this system have been compared with results obtained otherwise and good agreement was observed between them. This study has confirmed the need to improve the radiation shielding of KIPROS target-chamber and target vault in order to meet the radiological principles of dose rate limitation and optimization.

Quantitative physical measurements are necessary components of the International Atomic Energy Agency (IAEA) nuclear material safeguards verification regime. In December 1994, IAEA safeguards were initiated on an inventory of plutonium-bearing oxide and scrap items in Vault 3 of the 2736-Z Building of the Plutonium Finishing Plant on the United States Department of Energy's (USDOE) Hanford Site. The material originated in the United States nuclear weapons complex. The diversity of the chemical form and the heterogenous physical form of the plutonium in this inventory were expected to challenge the target precision and accuracy of methods employed by IAEA: quantitative destructive analytical techniques (which are susceptible to sampling error) and quantitative coincident neutron measurements (which rely on knowledge of the material's chemical form and purity). Because of the diverse and heterogenous nature of plutonium-bearing scrap, plant operations increasingly have adopted calorimetric techniques both for item inventory measurements and for verification purposes. During the recent advent of IAEA safeguards at Vault 3, a set of destructive and nondestructive methods were applied to a number of inventory items (cans of plutonium-bearing powders) with widely ranging chemical purities. Results of these measurements, gathered by the operator's and IAEA's laboratories and instruments as well as by instruments from Pacific Northwest Laboratory and USDOE's Los Alamos National Laboratory (LANL), are presented and statistically compared

Laparoendoscopic single site totally extraperitoneal (TEP) hernia repair showed to be a feasible alternative to conventional laparoscopic hernia repair; nevertheless single site surgery, with the loss of instruments triangulation can be a demanding procedure. To overcome those hurdles, the Single Site® (SS) platform of the da Vinci (DV) Si robotic system enables to perform surgical procedures through a 25-mm skin incision, with a stable 3D vision and restoring an adequate triangulation of the surgical instruments. We present in details the technique and the preliminary results of DV-SS TEP, to our knowledge the first cases reported in literature. In March 2016, three consecutive male patients (mean age 46.6 years-mean BMI 25.3) with bilateral symptomatic inguinal hernia were submitted to DV-SS TEP in our institutions. Feasibility, codification of the technique, operative time and perioperative outcomes were recorded. All the procedures were completed as scheduled, with no conversion to other techniques. Mean operative time was 98.6 min, ranging between 155 and 55 min, reflecting the learning curve of the operating room team on this new procedure. No intraoperative or postoperative complications were experienced and all the patients were discharged within 24 h after surgery. Patients reported satisfactory postoperative course, with no recurrence of inguinal hernia and satisfaction in cosmetic result at 6-month follow-up. DV-SS TEP inguinal hernia repair showed to be feasible and effective surgical option for bilateral groin hernia repair. Patients' outcome was uneventful, with optimal cosmetic results. Further studies comparing this innovative technique to TEP or LESS TEP should be promoted.

Herein, we describe several steps to improve surgeon autonomy during a Left Robotic-Assisted Laparoscopic Radical Nephrectomy (RALRN), using the Da Vinci Si system. Our kidney cancer program is based on 2 community hospitals. We use the Da Vinci Si system. Access is obtained with the following trocars: Two 8 mm robotic, one 8 mm robotic, bariatric length (arm 3), 15 mm for the assistant and 12 mm for the camera. We use curved monopolar scissors in robotic arm 1, Bipolar Maryland in arm 2, Prograsp Forceps in arm 3, and we alternate throughout the surgery with EndoWrist clip appliers and the vessel sealer. Here, we described three steps and the use of 3 robotic instruments to improve surgeon autonomy. Step 1: the lower pole of the kidney was dissected and this was retracted upwards and laterally. This maneuver was performed using the 3rd robotic arm with the Prograsp Forceps. Step 2: the monopolar scissors was replaced (robotic arm 1) with the robotic EndoWrist clip applier, 10 mm Hem-o-Lok. The renal artery and vein were controlled and transected by the main surgeon. Step 3: the superior, posterolateral dissection and all bleeders were carefully coagulated by the surgeon with the EndoWrist one vessel sealer. We have now performed 15 RALRN following these steps. Our results were: blood loss 300 cc, console time 140 min, operating room time 200 min, anesthesia time 180 min, hospital stay 2.5 days, 1 incisional hernia, pathology: (13) RCC clear cell, (1) chromophobe and (1) papillary type 1. Tumor Stage: (5) T1b, (8) T2a, (2) T2b. We provide a concise, step-by-step technique for radical nephrectomy (RN) using the Da Vinci Si robotic system that may provide more autonomy to the surgeon, while maintaining surgical outcome equivalent to standard laparoscopic RN.

Quantitative physical measurements are a n component of the International Atomic Energy Agency (IAEA) nuclear material m ampersand guards verification regime. In December 1994, LA.FA safeguards were initiated on an inventory of excess plutonium powder items at the Plutonium Finishing Plant, Vault 3, on the US Department of Energy's Hanford Site. The material originl from the US nuclear weapons complex. The diversity of the chemical form and the heterogenous physical form of this inventory were anticipated to challenge the precision and accuracy of quantitative destructive analytical techniques. A sampling design was used to estimate the degree of heterogeneity of the plutonium content of a variety of inventory items. Plutonium concentration, the item net weight, and the 240 Pu content were among the variables considered in the design. Samples were obtained from randomly selected location within each item. Each sample was divided into aliquots and analyzed chemically. Operator measurements by calorimetry and IAEA measurements by coincident neutron nondestructive analysis also were performed for the initial physical inventory verification materials and similar items not yet under IAEA safeguards. The heterogeneity testing has confirmed that part of the material is indeed significantly heterogeneous; this means that precautionary measures must be taken to obtain representative samples for destructive analysis. In addition, the sampling variability due to material heterogeneity was found to be comparable with, or greater than, the variability of the operator's calorimetric measurements

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.

Apesar de ser uma área ainda pouco explorada, é crescente o número de estudos dessas espécies nativas, dentre eles, os que abrangem as técnicas de cultura de tecidos. Isso se deve uma vez que essa ferramenta biotecnológica permite a propagação de espécies com dificuldade de germinação, minimiza o problema de sementes recalcitrantes, promove a produção de mudas em larga escala, complementa bancos de germoplasma e facilita as trocas de materiais genéticos. Dessa maneira, esta revisão visa a sumarizar o histórico e panorama atual das aplicações da cultura de tecidos em fruteiras do cerrado, proporcionando sustentação para novos estudos.Currently, it's been given a huge concern to the cerrado plants, focusing on fruit trees due to their characteristics and uses. Despite being a fairly unexplored area, the number of studies on these native species has increased, especially those involving tissue culture techniques. That's because this biotechnological tool provides the propagation of species with germination difficulty, reduces problems of recalcitrant seeds, promotes large scale seedling production, complements germplasm banks and facilitates the exchange of genetic materials. Therefore, this review summarizes the history and current situation of tissue culture techniques applied to Brazilian Cerrado fruit trees, providing support to further studies.

This work presents a preliminary study about the viability and adequacy of a new methodology for the definition of one of the main properties of ion exchange resins used for isotopic separation. Basically, the main problem is the definition of pelicule diameter in case of pelicular ion exchange resins, in order to achieve the best performance in the shortest time. In order to achieve this, a methodology was developed, based in two classic techniques of Artificial Intelligence (AI). At first, an artificial neural network (NN) was trained to map the existing relations between the nucleus radius and the resin's efficiency associated with the exchange time. Later on, a genetic algorithm (GA) was developed in order to find the best pelicule dimension. Preliminary results seem to confirm the potential of the method, and this can be used in any chemical process employing ion exchange resins. (author)

In this paper we perform exergetic and exergoeconomic analyses, a mathematical optimization and an exergoeconomic optimization of a gas turbine-heat recovery boiler cogeneration system with fixed electricity and steam production rates. The exergy balance is calculated with the IPSE pro thermal system simulation program. In the exergetic analysis, exergy destruction rates, exergetic efficiencies and structural bond coefficients for each component are evaluated as functions of the decision variables of the optimization problem. In the exergoeconomic analysis the cost for each exergetic flow is determined through cost balance equations and additional auxiliary equations from cost partition criteria. Mathematical optimization is performed by the metric variable method (software EES - Engineering Equation Solver) and by the successive quadratic programming (IMSL library - Fortran Power Station). The exergoeconomic optimization is performed on the basis of the exergoeconomic variables. System optimization is also performed by evaluating the derivative of the objective function through finite differences. This paper concludes with a comparison between the four optimization techniques employed. (author)

To determine optimized dose limits for workers, a study of optimization of radiation protection was undertaken in gamma radiography facilities closed, using the Technique Multiple Attributes Utility Analysis. A total of 217 protection options, distributed in 34 irradiation scenarios for tree facility types ( fixed open, moveable and closed (bunker) were analyzed. In the determination of the optimized limit dose, the following attributes were considered; costs of the protection barriers, costs attributed to the biological detriment for different alpha (the reference value of unit collective dose), size of the isolation area, constrained limits dose of annual individual equivalent doses and collective dose. The variables studied in the evaluation included: effective work load, type and activity of the sources of radiation ({sup 192}Ir and {sup 60}Co), source-operator distance related to the characteristic of the length of the command cable and the guide tube, type and thickness of the materials used in the protection barriers (concrete, barite, ceramic, lead, steel alloy and tungsten). The optimal analytic solutions obtained in the optimization process that resulted in the indication of the optimized dose limit were determined by means of a sensitivity analysis and by direct and logic evaluations, thus, independent of the values of the monetary coefficient attributed to the biological detriment, of the annual interest rate applied to the protection cost and of the type of installation studied, it was concluded that the primary limit of annual equivalent dose for workers (now 50 mSv) can be easily reduced to an optimized annual dose limit of 5 mSv.

Analysis about the washing efficiency of piassava fiber from Attalea Funifera Martius species was performed in this study, as well as the sieving and grinding processes to obtain the fiber size less than 270 mesh. Two types of fiber were experimented: in natura and after washing with soap. The fibers were ground in three different mills; the knife mill presented the best grinding efficiency, with yield around 7.45%, for 15 min of sieving and 5Hz as processing parameters. The fibers were characterized by means of X-ray diffraction (XRD) and optical microscopy (OM). Both fibers presented XRD diffraction peak around 22 deg, due to the crystalline structure of cellulose. OM analyses suggested that the soap solution provided a partial cleaning on the fiber surfaces. (author)

This paper compared three techniques of skin total irradiation with electrons: 1) horizontal positioning, 2) vertical positioning - rotatory technique and 3) vertical positioning - six fields technique. For that, a anthropomorphic phantom was positioned according to the recommendation for each technique and was i radiated at the linear accelerator by using the 6 MeV electrons. Radiochromic films were positioned on the surface in various regions of the phantom for measurement of absorbed dose. A ionization chamber was positioned inside of equivalent issue plates for dose evaluation due to the photons produced by electron stopping. The technique 2 and 3 have shown too similar in the results and number or discrepant points (8 and 10 respectively) of prescription lower than the technique 1 (22 points). The total body dose of photons of the 1, 2 and 3 techniques was 2.2%, 5.3% and 5.2% respectively

This thesis presents a text mining method for semi-automatic extraction of taxonomy of concepts, from a textual corpus composed of scientific papers related to nuclear area. The text classification is a natural human practice and a crucial task for work with large repositories. The document clustering technique provides a logical and understandable framework that facilitates the organization, browsing and searching. Most clustering algorithms using the bag of words model to represent the content of a document. This model generates a high dimensionality of the data, ignores the fact that different words can have the same meaning and does not consider the relationship between them, assuming that words are independent of each other. The methodology presents a combination of a model for document representation by concepts with a hierarchical document clustering method using frequency of co-occurrence concepts and a technique for clusters labeling more representatives, with the objective of producing a taxonomy of concepts which may reflect a structure of the knowledge domain. It is hoped that this work will contribute to the conceptual mapping of scientific production of nuclear area and thus support the management of research activities in this area. (author)

The aim of this present study was to verify the effects of gamma radiation on the growth of Aspergillus flavus Link aflatoxins producer; to demonstrate the application of Polymerase Chain Reaction (PCR) technique in the diagnostic of A. Flavus, as well to verify the effect of radiation in the profile of DNA bands. Twenty samples of grains maize with 200 g each were individually irradiated with 20 kGy, to eliminate the microbial contamination. In following, the samples were inoculated with an toxigenic A. flavus (1x10{sup 6} spores/ml), incubated for 15 days at 25 deg C with a relative humidity of around 97,5% and irradiated with 0, 2; 5 and 10 kGy. The samples, 5 to each dose of irradiation, were individually analyzed for the number of fungal cells, water activity, viability test (fluorescein diacetate and ethidium bromide), PCR and aflatoxins (AFB) detection. The results showed that the doses used were effective in reducing the number of Colony Forming Units (CFU/g) mainly the doses of 5 and 10 kGy. In addition, the viability test showed a decrease of viable cells with increase of irradiation doses. The reduction of AFB{sub 1} and AFB-2, was more efficient with the use of 2 kGy in comparison with the dose of 5 kGy, while the dose of 10 kGy, degraded the aflatoxins. Thereby, it was observed that AFB2 showed to be more radiosensitive. The use of PCR technique showed the presence of DNA bands, in all samples. (author)

The use of environmental monitoring as a technique to identify activities related to the nuclear fuel cycle has been proposed, by international organizations, as an additional measure to the safeguards agreements in force. The elements specific for each kind of nuclear activity, or nuclear signatures, inserted in the ecosystem by several transfer paths, can be intercepted with better or worse ability by different live organisms. Depending on the kind of signature of interest, the anthropogenic material identification and quantification require the choice of adequate biologic indicators and, mainly, the use of sophisticated techniques associated with elaborate sample treatments. This work demonstrates the technical viability of using pine needles as bioindicators of nuclear signatures associated with uranium enrichment activities. Additionally, it proposes the use of a technique widely diffused nowadays in the scientific community, the High Resolution Inductively Coupled Plasma Mass Spectrometer (HR-ICP-MS), to identify the signature corresponding to that kind of activities in the ecosystem. It can be also found a description of a methodology recently being applied in analytical chemistry,based on uncertainties estimates metrological concepts, used to calculate the uncertainties associated with the obtained measurement results. Nitric acid solutions with a concentration of 0.3 mol.kg{sup -1}, used to wash pine needles sampled near facilities that manipulate enriched uranium and containing only 0.1 {mu}g.kg{sup -1} of uranium, exhibit a {sup 235} U: {sup 238} U isotopic abundance ratio of 0.0092{+-}0.0002, while solutions originated from samples collected at places located more than 200 km far from activities related to the nuclear fuel cycle exhibit a value of 0.0074{+-}0.0002 for this abundance ratio. Similar results were obtained for samples collected in different places permit to confirm the presence of anthropogenic uranium and demonstrate the viability of using

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)

This paper presents an experimental study of natural two-phase flow in a circuit that simulates, on a smaller scale, a typical residual heat removal system of passive reactors APWR (Advanced Pressurized Water Reactor). The circuit was formed by a heater, a heat exchanger and piping. The experimental study was the application of a visualization technique, using a high speed camera, for measuring the size and speed of vapor bubbles generated in the heater with different power heating. The camera was positioned in the central region of the pipe connecting the heater to the heat exchanger, where there is a clear passage. The flow of images were processed and analyzed using commercial software that allowed the determination of the length and velocity of the bubbles. The results were then compared with correlations available in literature.

The SysSen is composed by a questionnaire (Senior Questionnaire of Physical Activities - QSAP and a field test (Senior 'Walking and Carrying' Test - TSMP. The QSAP is a four-part interview, assessing the necessities for an autonomous life related to upper body strength (FO and cardiorespiratory capacity (PA. The first one considers home, professional, and free time activities. The second observes the environmental context. The third assesses the difficulties to perform day-to-day activities and the feelings of the subjects towards activities they would like to perform/resume. The last part considers the interviewer's point of view on the assessed information. An index for QSAP overall results is obtained (Expressed Autonomy Index - IAE. In the TSMP, subjects walk 800 m the faster they can, carrying weights according to sex. An index for the physical functional potential for activities that depend on FO and PA is calculated (Potential Autonomy Index - IAP. Both indexes are used to determine a ratio between potential and expressed autonomy (IAP/IAE - the Senior Index for Action Autonomy (ISAC. The SysSen validity was verified by comparing its partial and final results with other evaluation techniques, and by the internal and structural consistence of the indices obtained (construct, content, and external validity.

In this paper, nuclear techniques have been used to describe structural characteristics of ceramic samples. These samples were produced to serve as simulates of sandstones and their mainly component was silica (SiO{sub 2}). Three sets of these samples with different characteristics were analyzed with the gamma ray transmission and the X-ray microtomography. They had the function to describe parameters as porosity point to point and total average porosity, for the transmission case, and 2D sections average porosity, total average porosity and size porous distribution for microtomography, as well as to investigate possible irregularities in bulk sample. The experimental set up for the gamma ray transmission technique consisted of: a 2 x 2 crystal NaI(Tl) detector, an {sup 241}Am radioactive source (59.54 keV, 100 mCi), an automatic micrometric table for the sample XZ movement and standard gamma spectrometry electronics. Lead collimators with 2 mm diameter were placed on the source way out and on the detector entrance. The microtomographic measurements were done with a Skyscan system, model 1172, with a X-ray tube with 20-100 kV of voltage range and a CCD camera. Employing gamma ray transmission method was possible to obtain overall porosity values from 25.8 to 34.0 % and from 24.8 to 29.2 % for samples with parallelepiped and cylinder shape, respectively, for ceramic I set; from 58.5 to 61.0 % and from 57.1 to 61.7 % for the same geometric shape of ceramic II set. The samples analyzed by the microtomography achieved resolutions of 1.73 {mu}m, 0.64 {mu}m and 1.28 {mu}m for samples of ceramic set I, II and III, respectively. This methodology provided average total porosity values from 26.6 to 29.4 %, from 48.4 to 51.0 % and from 28.2 to 30.6 % to I, II and III ceramic sets, respectively.

In general, the two main problems associated to the water injection system for secondary petroleum recovery are the corrosion control and the decrease in solid injection in the reservoir. Corrosion problems in injection water systems may have abiotic as well as biotic causes, and the occurrence of reservoir plugs can result from the injection of particles (suspended solids as well as corrosion products), bacteria and fouling formation. Due to the need to implement a methodology for the evaluation of abiotic and biotic corrosive processes, monitoring techniques and MIC control in a dynamic system, an apparatus was built that simulates the characteristics of a water injection system. The apparatus allows monitoring and control of the parameters that, when varied, may influence the performance of the quality of the injected water. The dynamic system was designed to simulate as precisely as possible the conditions that allow the SRB and heterotrophic bacteria to create fouling in a water injection system. This article discusses the dynamic system, analytical methods and some preliminary results. (author)

Great problems are found by who need to get a power plant capable to mostly make possible the deriving food production of the fruits. The use of the electric energy of the plants and micron-plant is one of the main factors for the rise in the cost of the production. The use of alternative sources of energy sells at a loss a little this cost. Of this form, this project of integrated system of production of energy for agroindustry, supported for the CNPq, becomes advantageous all the investments that come to be made in this direction. The objective of the research is to develop a new synthesis of processes for use of vegetal biomass (wood) for production of the applied electric energy in the process of manufacture of jelly of fruits with co-production of activated coal. Our project of residual biomass produces energy from the wood saw pyrolysis and gasification. And also uses the substitution of the glucose found in the sugar for the pectin, proceeding from the rinds of fruits. Comparative results indicate that this substantiates (pectin) is sufficiently efficient in the control of the cholesterol level of the blood and also is very rich in the energy supply for the people who consume them. After carried through bibliographical research on the current state of the technology of the production of energy based on the vegetal biomass of firewood, processes of term conversion, reactor of activation and equipment, to leave of this had been developed engineering projects, with the use of the tool Super ProDesigner 4.9. Some simulations of processes of fast pyrolysis, gasification, separation of bio oil, generation of energy including system of integration of energy production as innovation of the considered work had been made. To leave of this, two scenes had been developed: one, the current process of production and the other, our innovation, being studied at great length the project of investment and costs, analysis of viability and cash flux using software Orcamento 2004. The results of diverse technician-economic parameters of this scene had been compared and analyzed, where a good energy and material income of practised conventional process in the country was observed. The modeling proposed involves the integrated system that allows the valuation of the jelly of fruits with improved economic viability of efficient form. Considering the viability and low cost of this process and the diverse analyzed economic parameters it is intended to contribute for the supply of a more healthful food for the population. (author)

Electrical power could be considered as one of the economy propulsion vector of a country, assuming extremely important and strategic role because it makes direct influence to the production capacity. The expansion of electrical energy production could not only be done in a short time because constructions in this area take many years and could require more then a decade depending on the magnitude of them. The national power generation group is constituted mainly by hydro power plants complemented by thermal power plants which use several kinds of fuel which generation cost is high, if compared to hydro power generation, and should be minimized. It is a complex planning issue to supply the future power demand which basically depends on the analysis of two compoundable scenarios: the first one refers to the forecast of future economy growing and in this case, unless unpredictable issues occur such as the recent high economy growing experimented by China, the future demand does not show any surprise and is easy to predict; the second one, has inside the uncertainty because the hydro plants productions depends on the water quantity of rivers which depends on the past and current rainfall regimen. The quantity of rainfall is a stochastic data and follows the rules of probability and this drives to the study of cases and its deployments which are numerous causing difficulties to forecast the future. The planning of the electrical area has to examine the future demand and provide the necessary power generation equipment assuming a certain risk. To have it done, simulation models are used to predict the future, combining the two scenarios cited before, and viewing the results promoted by decision took in a step before. The difficult of this task is caused by the big amount of future alternatives provided by the combinatorial phenomena which require, to process the model, a computer with high processing capacity and specialized and specific methods that can resolve this king of problem. Because of the importance and magnitude of this issue, every effort which contributes to the improvement of power planning is welcome and this corroborates with this thesis which has an objective to propose technical, viable and economic solutions to solve the optimization problems with a new approach and has potential to be applied in many others kind of similar problems.

Our goal was to evaluate the exposure factors that can change the image noise of head CT in different slices thicknesses. We have evaluated the images noise at several mAs varying from 50 to 800 mAs for 100, 120 and 140 kVp as tension values. The images uniformity were determined for all technical exposure conditions. We did not observed any important noise reduction for values up 200 mAs which can justify the increase of radiation doses through the increase of mAs. (author)

Full Text Available A análise diagnóstica da medula óssea compreende classicamente a citologia. Mais recentemente, tornou- se rotina o estudo histológico. Desde o início, tentou- se integrar estes dados, pois, enquanto a citologia fornece uma análise mais detalhada das características das células e permite quantificá- las, a biópsia, por analisar o tecido como um todo, permite o estudo da estrutura do tecido hemopoético, seu estroma e a ocorrência de estruturas estranhas à medula, como granulomas, fibrose e metástases de neoplasias. Com o desenvolvimento de novas tecnologias e o melhor conhecimento das diversas entidades, principalmente em onco- hematologia, além do desenvolvimento de terapias alvo- específicas, tornou- se importante o estudo citogenético/molecular em algumas patologias. Nas leucemias agudas e síndromes linfoproliferativas, a imunofenotipagem tem contribuído de modo decisivo para a classificação correta das diversas neoplasias pelos critérios da OMS. Assim, o diagnóstico hematológico se tornou uma atividade multidisciplinar que integra profissionais de diversas especialidades. Assim se consegue tratar os pacientes de modo mais adequado, além de poder rastrear a doença residual após o tratamento. Isto levou a novas definições de remissão: hematológica, fenotípica, citogenética e molecular. O estudo da medula óssea é importante em algumas hemopatias benignas, como anemias carenciais, que podem se manifestar como pancitopenias. Este estudo deve ser complementado com exames sorológicos e bioquímicos.

A methodology for studies and evaluation of sewage treatment plants with radioactive tracers is presented.. Radioisotopes as {sup 82} Br ( for the liquid phase), {sup 110m} Ag and {sup 140} La, (for the solid phase) was used to evaluate sewage flow rates, mixing pattern in equalization tank and test effluent treatment units. The tracer was injected in the unit (instantaneously or in a constant rate with a pump) and NaI-scintillation detectors measured the output signal. The Fortran program TRACADORES was developed to analyze the response function of the units in form of residence times distribution curves (RTD), which represents the probability of an element of the material to interact with the unit, and calculate the mean residence time {gamma}, the central moment of this distribution function. This fundamental parameter characterizes the tank and serves as a quantitative evaluation for its performance. With the radiotracer techniques was possible to identify dead zone, channeling, internal circulation of the solid phase inside the tanks. The technique represents a guideline for redesign a imperfect unit and eliminate the problem. (author)

The apparatus permitted renewal of the liquid medium without substantial variations in pressure, thus eliminating excretion products and maintaining the desired O2 level and thereby permitting us to evaluate the effects of pressure independently of the occurrence of anoxia. Pressure was maintained without any contact of the liquid medium with compressed air, a situation which reproduced with relative fidelity what occurs in nature and assured the presence of the same amounts of gases in the two observation chambers (Control and Experimental. Biomphalaria glabrata was found to be able to survive at least 48 hours when submitted to 49.02 x 10**4 Pa (equivalent to a water depth of 48.8 m, continuing to day egg masses and showing few behavioral changes when compared with the control group.Para estudar mudanças na sobrevivência, atividades biológicas e comportamento de planorbídeos submetidos a aumento de pressão hidrostática, desenvolvemos uma técnica que utiliza duas câmaras transparentes e um pistão hidráulico.

Sand production in petroleum holes is a critical problem in separation plants in petroleum platforms. Sand may cause severe erosion in valves and lines and its accumulation in main process devices may force stopping the process for cleaning. This may be responsible for huge production loses. In this work, the geometrical proportions of a cyclone with high efficiency for sand-gas separation. For that, experimental design was employed to select the geometries to be studied. The separation efficiency was obtained by Computational Fluid Dynamics technique, with the commercial software CFX, version 11.0. This tool numerically solves the conservation equations, which permits estimating fluid and particles trajectory inside the equipment. Then, it was possible to obtain a model and based on that to find the geometry that gives the best efficiency to the proposed service. (author)

Hydroxyapatite (HAP) belongs to the family of calcium apatites. In nanometric form (nHAP) can be used as a drug carrier. The objective was to improve PLA nanofibers with nHAP insert for use in drug delivery. nHAP were obtained by coprecipitation method and characterized by XRD and TEM techniques. PLA fibers (10%) and 5% nHAP were obtained at a distance of 6 cm and flow rate of 0.1, 0.3 and 0.5 ml h{sup -1}, and characterized by SEM. The nHAP were single phase with rod shape, rounded tip and from 10 to 20 nm in diameter. The fibers obtained from pure PLA had to be more porous than in the presence of HAP. The diameters ranged from 0.2 to 2.4 micrometers. Among the fibers obtained that showed the best result was to flow 0.3 ml h{sup -1}. (author)

This work shows a new approach to solve availability maximization problems in electromechanical systems, under periodic preventive scheduled tests. This approach uses a new Optimization tool called PSO developed by Kennedy and Eberhart (2001), Particle Swarm Optimization, integrated with probabilistic safety analysis model. Two maintenance optimization problems are solved by the proposed technique, the first one is a hypothetical electromechanical configuration and the second one is a real case from a nuclear power plant (Emergency Diesel Generators). For both problem PSO is compared to a genetic algorithm (GA). In the experiments made, PSO was able to obtain results comparable or even slightly better than those obtained b GA. Therefore, the PSO algorithm is simpler and its convergence is faster, indicating that PSO is a good alternative for solving such kind of problems. (author)

MÉTODOS: A fratura foi reproduzida em 40 úmeros plásticos, divididos em grupos de dez conforme a técnica de fixação, cada uma delas empregando diferentes recursos de fixação, em configurações distintas. Os modelos umerais foram montados em uma escápula de alumínio, com tiras de couro mimetizando os tendões do capuz rotador, e submetidos a ensaios de encurvamento e de torção em uma máquina universal de ensaios, usando a rigidez relativa como parâmetro de avaliação. Montagens com o úmero intacto foram analisadas para comparação. RESULTADOS: O comportamento biomecânico das técnicas de fixação variou dentro de uma ampla faixa, as montagens incluindo a placa DCP e os parafusos de 4,5mm de diâmetro sendo significantemente mais rígidos do que as montagens com os fios de Kirschner e os parafusos 3,5 mm de diâmetro. CONCLUSÃO: As quatro técnicas foram capazes de suportar cargas compatíveis com a demanda fisiológica, mas aquelas com a maior rigidez relativa devem ser as preferidas para finalidades clínicas.

This work presents results of non destructive mass analysis of natural uranium by the pulsed source technique. Fissioning is produced by irradiating the test sample with pulses of 14 MeV neutrons and the uranium mass is calculated on a relative scale from the measured emission of delayed neutrons. Individual measurements were normalised against the integral counts of a scintillation detector measuring the 14 MeV neutron intensity. Delayed neutrons were measured using a specially constructed slab detector operated in anti synchronism with the fast pulsed source. The 14 MeV neutrons were produced via the T(d,n) {sup 4}He reaction using a 400 kV Van de Graaff accelerated operated at 200 kV in the pulsed source mode. Three types of sample were analysed, namely: discs of metallic uranium, pellets of sintered uranium oxide and plates of uranium aluminium alloy sandwiched between aluminium. These plates simulated those of Material Testing Reactor fuel elements. Results of measurements were reproducible to within an overall error in the range 1.6 to 3.9%; the specific error depending on the shape, size and mass of the sample. (author)

During the operation of a nuclear plant and other industrial plants, the operational time and the exposition to severe working conditions may cause the wear of its components, consequently, compromising the safety and the performance of the installation. The implementation of periodical inspections helps to ensure the safe operation and the best performance of the plant. In this way, the use of ultrasonic techniques for inspection and materials characterization becomes more and more attractive, since they offer quick, precise results and are technically ease to implement. The usual ultrasonic techniques, need to the measure the travelling time of the ultrasonic wave in the material examined in order to extract information useful to characterize it. Thus, the measurement of the travelling time of the ultrasonic wave is the overriding factor in most of the applications made with ultrasound. In this work a new technique was developed for measuring the travelling time of the ultrasonic wave using a Fourier's Fast Transformer (FFT). It will be shown mathematically and experimentally that it is possible to use the ultrasonic signal in the frequency domain to determine the travelling time of the ultrasonic wave. Five experiments were carried out for the experimental validation of this new technique. The materials used were 20 ceramic pastilles with different porosities and 3 aluminum plates of different thicknesses. The obtained results have shown that the new technique proposed in this work was able to determine the travelling time of the ultrasonic wave with the same precision as the conventional technique. It was shown, furthermore, that this new technique is able to measure the travelling time of the ultrasonic wave in situations where the conventional technique cannot be applied greatly expanding the range of application of ultrasonic testing and inspections.

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)

In Brazil, the Regulatory Standard n. 13 (NR 13) establishes requirements for the inspection of boilers and pressure vessels which has main objective of preventing accidents with these types of equipment. Additionally, it has the Risk-Based Inspection (RBI) technique as an effective way to manage the mechanical integrity of various types of static mechanical equipment by through an inspection planning based on the risk factor. In this study, it is being proposed to include the RBI technique, in the NR 13, for the planning and definition of periods for the safety inspection of boilers and pressure vessels in order to promote an increase in the operational safety in process industries in Brazil. In this study it was carried out a critical analysis of NR 13 and RBI, and beyond that a bibliographic research of various international documents that relate the operational safety of pressurized equipment with the inspection activity, and the acceptability of RBI by governments, agencies and organizations around the world. It is considered that the inclusion and formal acceptance of RBI technique in the NR 13 must be accompanied by a rigorous control to avoid the 'trivialization' of its use and ensure the implementation rational, efficient and reliable. Finally, it was developed and suggested basic elements and minimum requirements to be inserted in the NR 13, to be attended, in order mandatory, by the companies that choose the implementation and use of the RBI technique as a tool for the planning of safety inspection of boilers and pressure vessels. It is concluded that the formal acceptance of the RBI technique in the NR 13 could aggregate much value to this standard, with regard to the prevention of accidents involving boilers or pressure vessels, and provide a technological jump to the companies that make use of RBI technique in Brazil.

Full Text Available Desde 1983, 40 pacientes consecutivos, portadores de estenose mitral com alterações subvalvares, tais como: fusão e encurtamento das cordas, associadas a sinéquia dos músculos papilares, foram submetidos a comissurotomia mitral a "céu aberto". Com o intuito de ganhar área efetiva maior de abertura da valva mitral (sem restrições, as comissuras foram abertas, amplamente, às vezes não respeitando as cordas que sustentam as cúspides. A insuficiência mitral provocada, em 4 casos, como conseqüência, foi corrigida mediante a transferência de 2 a 6 cordas, ao nível da borda livre da cúspide anterior, ou posterior, da valva, na região das comissuras. A presença de uma regurgitação central por falha na coaptação das cúspides valvares, foi tratada, em 12 casos, com o implante de anel profético de Carpentier. As anomalias do aparelho subvalvar foram abordadas pelas técnicas convencionais: desbridamento, ressecção e abertura dos músculos papilares. Dos 38 sobreviventes, 32 não apresentam sopro de regurgitação mitral e os 6 restantes, apenas sopro sistólico de +/+ +. A avaliação pós-operatória, mediante ecocardiografia bidemensional, demonstrou abertura valvar satisfatória e ausência de estenose residual. Os pacientes que apresentam sopro sistólico mitral residual foram estudados com Doppler, concluindo que se trata de regurgitação bem localizada e sem repercussão hemodinâmica. Esta nova técnica operatória pode ser "extensível" ao tratamento do prolapso da valva mitral.Since 1983, 40 consecutive patients with mitral stenosis and significant disease of the subvalvular apparatus underwent open heart mitral commissurotomy. The aim of the study was to evaluate the effects of an unrestricted dilatation of the two commissures followed by repair of the subsequent mitral regurgitation. The mitral regurgitation created by this procedure in 24 cases was corrected by transferring 2 to 6 chordae tendinae to the free border

This work presents the application of the X-ray microtomography and gamma ray transmission techniques for the microstructure characterization of different kinds of materials. Total porosity, pore size distribution and the two point correlation functions were measured. The two point correlation function, which allows the reconstruction of 3D models, was carried out for two samples. Seven ceramic tablets of Alumina (Al{sub 2}O{sub 3}), seven tablets of Boron Carbide (B{sub 4}C), three samples of sedimentary rocks and one sample of Titanium foam were analyzed. The experimental set up for the Gamma Ray Transmission technique consisted of: a 2'' x 2'' crystal NaI(Tl) detector, an {sup 241} Am radioactive source (59,53 keV, 100 mCi), an automatic micrometric table for the sample XZ movement and standard gamma spectrometry electronics. Two microtomography systems were used: a Fein Focus system, constituted by an X-ray tube, operated at 160 kV and 0.3 to 1.1 mA, a CCD camera and the movement sample system, and a Skyscan system, model 1072, with a X-ray tube operated at 100 kV and 100{mu}A, and a CCD camera. The ceramic tablets, analyzed by the gamma ray transmission technique presented results for most of the porosities data with smaller confidence intervals and inside the intervals supplied by the tablets manufacturer. The Titanium porous sample was analyzed by the two techniques, its microtomography images achieved a resolution of 17{mu}m, obtained employing the Fein Focus system. For both techniques, this sample showed high porosity, which allows its application for this purpose. The sandstones samples were analyzed by the Skyscan system, achieving resolutions of 19{mu}m, 11{mu}m and 3.8{mu}m for each sample, respectively. The resolutions of 11{mu}m and 3.8{mu}m were the ones that generated better 2D sections for the respective samples and, consequently, more reliable porosities. The 3.8{mu}m resolution was the one that best quantified the pore size

When working on a D and D project, it is best to keep the dismantling techniques and tools as simple as possible. The workers will be more efficient and safer using techniques that are familiar to them. Prior experience with the technique or use of mock-ups is the best way to keep workers safe and to keep the project on schedule

This study describes the purification and characterization of a stable protease activity isolated from Fasciola hepatica adult worms maintained in vitro by employing acetone precipitation (40-60%) followed by a gel filtration through Sephadex G-100 and DEAE- cellulose ion exchange column. Through this three-step purification, the enzyme was purified 11-fold with a specific activity of 1893.9U/mg and 31.5% recovery. After the final ultrafiltration step, the purification fold was increased up to 13.1 and the overall activity yield reached a rate of 18.8%. The MW of the purified protease was estimated by reducing SDS-PAGE to be 22kDa while the proteolytic activity detection was carried out by zymography on non-denaturing SDS-PAGE containing the casein as substrate. Using this substrate, the protease showed extreme proteolytic activity at pH 5.5 and temperature 35-40°C and was highly stable over a wide range of pH, from 5.0 to 10.0. In addition to its preference for the Z-Phe-Arg-AMC fluorogenic substrate resulting in maximum proteolytic activity (99.7%) at pH 7.0, the pure protease exhibited highest cleavage activity against hemoglobin and casein substrates at pH 5.5 (85.6% and 82.8%, respectively). The K m values obtained for this protease were 5.4, 13, 160 and approximately 1000μM using respectively the fluorogenic substrate Z-Phe-Arg-AMC, hemoglobin, casein and albumin. The protease activity was completely inhibited either by E-64 inhibitor (5mM) or iodoacetamide (10mM), indicating its cysteine nature. The usefulness of the purified protease as an antigen was studied by immunoblotting. Thus, sera from sheep experimentally infected with F. hepatica recognized the protease band at 2 weeks post-infection (WPI) and strongly at 7 WPI. The early detection of antibodies anti- F. hepatica suggests the application of this molecule as a specific epitope for the serodiagnosis of fascioliasis disease. Copyright © 2017 Elsevier B.V.

In the present work, the technique of microwave heating was used to study the immobilization of low and intermediate activity level radioactive waste, such as spent ion exchange resin used to remove undesirable ions of primary circuits of refrigeration in water refrigerated nuclear reactors, and those used in chemical and radionuclide separation columns in the quality control of radioisotopes. Bitumen matrices reinforced with some kinds of rubber (Neoprene{sup R}, silicon and ethylene-vinyl-acetate), from production leftovers or scraps, were used for incorporation of radioactive waste. The samples irradiation was made in a home microwave oven that operates at a frequency of 2.450 MHZ with 1.000 W power. The samples were characterized by developing assays on penetration, leaching resistance, softening, flash and combustion points, thermogravimetry and optical microscopy. The obtained results were compatible with the pattern of matrices components, which shows that technique is a very useful alternative to conventional immobilization methods and to those kinds of radioactive waste.

The {sup 10}B isotope tracer technique is essential to study the B mobility in plants. Factors that can influence the quality of measured B isotope ratios were optimized experimentally using High Resolution Inductively Coupled Plasma Mass Spectrometry (HRICP-MS). An isotopically certified standard (NIST SRM-951) was used. The best combination was obtained using a resolution of 400, a RF power of 1250 W, followed by 15 measurements over a 10-s integration period each (15*10). Utilizing this approach it was possible to obtain a precision of 0.3 % in standard material and 2z % in the experimental samples. The results show the importance of establishing optimized work conditions before carrying out the analytical series. (author)

In-service inspection has received diverse contributions from technologies and documents with the objective of maximizing equipment availability and minimizing inadequate repairs. Amongst the available technologies, there are the automated ultrasound tests, in the B and C-scan versions. This paper describes an evaluation methodology based on the correlation between the test techniques of instrumented electromagnetic PIG and automated ultrasound, both applied with the purpose of detecting and mapping areas with corrosion in pipes for oil transport. The main objective of the application of the C-scan methodology, in this case, was the measuring and detailing of the corroded area, thus providing an adequate maintenance plan through the substitution or installation of a double gutter. The result demonstrates the correlation between the measurements taken by the PIG and the sizing of the regions done using the C-scan method, consisting of the length, width and thickness values in the points affected by the corrosion.

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)

In this work, carbon thin films were produced by the magnetron sputtering technique using single crystal substrates of alumina c-plane (0001) and Si (111) and Si (100) substrates, employing Co, Ni and Cu as intermediate films (buffer-layers). The depositions were conducted in three stages, first with cobalt buffer-layers where only after the production of a large number of samples, the depositions using cooper buffer-layers were carried out on Si substrates. Then, depositions were performed with nickel buffer layers using single-crystal alumina substrates. The crystallinity of the carbon films was evaluated by using the technique of Raman spectroscopy and, then, by X-ray diffraction (XRD). The morphological characterization of the films was performed by scanning electron microscopy (SEM and FEG-SEM) and high-resolution transmission electron microscopy (HRTEM). The XRD peaks related to the carbon films were observed only in the results of the samples with cobalt and nickel buffer-layers. The Raman spectroscopy showed that the carbon films with the best degree of crystallinity were the ones produced with Si (111) substrates, for the Cu buffers, and sapphire substrates for the Ni and Co buffers, where the latter resulted in a sample with the best crystallinity of all the ones produced in this work. It was observed that the cobalt has low recovering over the alumina substrates when compared to the nickel. Sorption tests of Ce ions by the carbon films were conducted in two samples and it was observed that the sorption did not occur probably because of the low crystallinity of the carbon films in both samples.

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 same procedure was done with the eighteen samples which were analyzed through EDS and which had their buccal surface grinded and polished before the bleaching procedure in order to obtain more precise values of the fraction of calcium and phosphorus. The results showed no morphological changes among the analyzed control halves and the bleached halves. There was not a statistical significant difference about Ca and P values, among the control halves and the bleached halves regarding the chemical components (p< 0,05). (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)

Sample decomposition is a fundamental and integral step in the procedure of geochemical analysis. It is often the limiting factor to sample throughput, especially with the recent application of the fast and modern multi-element measurement instrumentation. The complexity of geological materials makes it necessary to choose the sample decomposition technique that is compatible with the specific objective of the analysis. When selecting a decomposition technique, consideration should be given to the chemical and mineralogical characteristics of the sample, elements to be determined, precision and accuracy requirements, sample throughput, technical capability of personnel, and time constraints. This paper addresses these concerns and discusses the attributes and limitations of many techniques of sample decomposition along with examples of their application to geochemical analysis. The chemical properties of reagents as to their function as decomposition agents are also reviewed. The section on acid dissolution techniques addresses the various inorganic acids that are used individually or in combination in both open and closed systems. Fluxes used in sample fusion are discussed. The promising microwave-oven technology and the emerging field of automation are also examined. A section on applications highlights the use of decomposition techniques for the determination of Au, platinum group elements (PGEs), Hg, U, hydride-forming elements, rare earth elements (REEs), and multi-elements in geological materials. Partial dissolution techniques used for geochemical exploration which have been treated in detail elsewhere are not discussed here; nor are fire-assaying for noble metals and decomposition techniques for X-ray fluorescence or nuclear methods be discussed. ?? 1992.

Photovoltaic solar energy is the direct conversion of solar energy into electricity and it has low impact to the environment during electric energy production. The main device of this technology is the solar cell and silicon is the substrate most used. The solar cells are electrically connected and encapsulated in order to form the photovoltaic module. The aims of this thesis are to optimize, develop and to analyse n{sup +}np{sup +} solar cells processed in n type Si-PV-FZ and with aluminum rear emitter formed in belt furnace. The optimization of solar cells by simulation is an important step before the device development. The software PC-1D and another program developed using Visual Basic language were used. Considering a metal grid formed by evaporation technique in vacuum ambient an efficiency of 16.8 % may be achieved. With screen printed grid, 15.8 % efficient solar cells were obtained. From the simulation results it was found that the screen printing metallization may become more viable than evaporation technique because there is low difference in the efficiency and the screen printing is a simpler technique. The experimental optimization of silicon wafers texture process resulted in reflectance of 12 %. This value is typical for monocrystalline silicon with textured surface. Experimental optimization of phosphorus front surface field shows a sheet resistance of (36 {+-} 4) {omega}/ for this region. This region was formed in a thermal step in a conventional furnace with POCl{sub 3}. It was found that after the phosphorus diffusion occurred gettering to specific temperature and time. It was verified that the minority carrier lifetime in the final of processing is similar to the initial value. The influence of steps sequence of front silver paste firing and rear diffusion/firing aluminium paste, of surface passivation and the influence of dry air flow during the aluminium paste diffusion/firing, of aluminium paste diffusion/firing temperature and of belt speed

Full Text Available O presente trabalho tem por objetivo tentar compreender a produção da imagem visual no teatro. Para isso se vale da apropriação livre do conceito de “dobra? de Gilles Deleuze para se referir à multiplicidade de imagens criadas pelas diversas modalidades artísticas. Como no teatro há o entrelaçamento de imagens verbais – palavras enunciadas pelo texto dramático ou teatral – com imagens visuais – a visualidade advinda da composição cênica concreta que organiza no espaço ator e objeto –, a ênfase só podia recair sobre estas duas formas imagéticas. No caso do teatro, surge ainda a percepção de que para além da materialidade da cena, outras imagens emergem do confronto entre palco e platéia. Nesse sentido, imagem teatral seria então aquilo que surge da interação entre ator e espectador. A contribuição desse trabalho pode estar no fato de atualizar certos conceitos sobre a criação da imagem poética na poesia e no cinema para aplicá-los ao teatro. Ao recuperar o pensa-mento de Otávio Paz, Alfredo Bosi, Sergei Eisenstein, entre outros, bus-ca-se promover uma reflexão mais aprofundada sobre a construção visual no teatro.

The objective of this study was to evaluate the reduction of the radiation dose and X-ray tube heating in computed tomography exams. Exams of the skull, abdomen and thorax were evaluated. It was verified that the technique used could be changed, suggesting new protocols and comparing image quality, radiation dose and X-ray tube heating. A mAs reduction could be done without compromising the diagnostic quality bringing a decrease up to 21,92% in the dose of skull exams, 20,25% for the examinations, abdomen and 22,06% for the examinations of thorax. The reduction on the X-ray tube heating for skull, abdomen and thorax exams was approximately 22,2%, 20,0% and 22,2% respectively. It is concluded that a change on the described protocols will cause a significant reduction dose delivered to patients and on X-ray tube heating without compromising the diagnosis. (author)

Genetic Algorithms (GAs) are biologically motivated adaptive systems which have been used, with good results, in function optimization. However, traditional GAs rapidly push an artificial population toward convergence. That is, all individuals in the population soon become nearly identical. Niching Methods allow genetic algorithms to maintain a population of diverse individuals. GAs that incorporate these methods are capable of locating multiple, optimal solutions within a single population. The purpose of this study is to test existing niching techniques and two methods introduced herein, bearing in mind their eventual application in nuclear reactor related problems, specially the nuclear reactor core reload one, which has multiple solutions. Tests are performed using widely known test functions and their results show that the new methods are quite promising, specially in real world problems like the nuclear reactor core reload. (author)

Full Text Available Among the copper sulphides, chalcopyrite (CuFeS2, covellite (CuS and chalcocite (Cu2S are the most important source of minerals for copper mining industry. The acknowledge of behaviour of these sulphides related with bacterial leaching process are essential for optimization procedures. Despite of its importance, covellite has not deserved much interest of researchers regarding this matter. In this work it was studied the oxidation of covellite by the chemolithotrophic bacterium Thiobacillus ferrooxidans by using electrochemical techniques, such as open circuit potentials with the time and cyclic voltammetry. The experiments were carried out in acid medium (pH 1.8, containing or not Fe2+ as additional energy source, and in different periods of incubation; chemical controls were run in parallel. The results showed that a sulphur layer is formed spontaneously due the acid attack, covering the sulphide in the initial phase of incubation, blocking the sulphide oxidation. However, the bacterium was capable to oxidize this sulphur layer. In the presence of Fe2+ as supplemental energy source, the corrosion process was facilitated, because ocurred an indirect oxidation of covellite by Fe3+, which was produced by T. ferrooxidans oxidation of the Fe2+ added in the medium.

In Brazil, the expansion of agricultural areas causes several problems on natural resources. With the increasing occupation of the Cerrado region by agriculture, a series of environmental problems like deforestation, soil erosion and soil compaction are appearing and causing radical transformations in the natural landscape due to removing almost all native vegetation. The conventional tillage system (CTS) is considered an inadequate form of soil management for its frequently irremediable consequences of soil compaction and soil erosion, and the no till system (NTS) makes the maintenance of the soil conditions possible, letting them close to the natural environment, thus reducing rates of soil erosion. The objective of this work was to evaluate the efficiency of riparian forests in the retention of sediments originated for three different tillage systems, through the fallout {sup 137}CS redistribution technique, the Universal Soil Loss Equation (USLE) and some physical and chemical parameters that indicate the structural conditions of the soils of Goiatuba and Jandaia-GO. In the three areas, soil profiles were collected in three layers of 20 cm (0-20, 20-40 and 40-60 cm) at distinct points located along linear transects in the direction of the maximum slope until the riparian forest. In the riparian forest of each area, trenches were opened and soil was sampled to evaluate the activity of {sup 137}Cs and the physical and chemical parameters of soil. Detection of the activity of {sup 137}Cs was made with a gamma ray detector model (GEM-20180P, EG and ORTEC) connected to a multichannel analyzer. The comparison of averages was made using the Tukey test at 5% level of significance. The. results indicated that, the three soil tillage systems presented high rates of soil erosion and deposition of sediments and the riparian forest of the areas under CTS, NTS and pasture, located downstream received great amounts of sediments, and that only the riparian forest of CTS was

The report presents a wide, easily understandable description of presentation technique and man-machine communication. General fundamentals for the man-machine interface are illustrated, and the factors that affect the interface are described. A model is presented for describing the operators work situation, based on three different levels in the operators behaviour. The operator reacts routinely in the face of simple, known problems, and reacts in accordance with predetermined plans in the face of more complex, recognizable problems. Deep fundamental knowledge is necessary for truly complex questions. Today's technical status and future development have been studied. In the future, the operator interface will be based on standard software. Functions such as zooming, integration of video pictures, and sound reproduction will become common. Video walls may be expected to come into use in situations in which several persons simultaneously need access to the same information. A summary of the fundamental rules for the design of good picture ergonomics and design requirements for control rooms are included in the report. In conclusion, the report describes a presentation technique within the Distribution Automation and Demand Side Management area and analyses the know-how requirements within Vattenfall. If different systems are integrated, such as geographical information systems and operation monitoring systems, strict demands are made on the expertise of the users for achieving a user-friendly technique which is matched to the needs of the human being.

Depois de citar os 4 principais complexos epidemiológicos da peste e afirmar que tôda a profilaxia da doença consiste em atingir os dois primeiros elos dessas cadeias e proteger o último, passa a classificar os vários métodos profiláticos empregados em 2 grandes grupos: o das medidas destrutivas ou provisórias e o das medidas supressivas ou definitivas. Entre as primeiras arrola a desratização e a despulização, às quais acrescenta o tratamento e isolamento do doente e do portaãor, e entre as segundas inclui a anti-ratização e a imunização. A seguir, passa a explicar em que consistem essas várias medidas profiláticas e quais os agentes de que se tem lançado mão para executá-las, expendendo ao curso dessa exposição o conceito que formula a respeito de cada uma delas, à guisa de apreciação do seu valor relativo.

The use of computed tomography has increased significantly over the past decades. In Brazil the use increased more than twofold from 2008 to 2014, in the meantime the abdomen procedures have tripled. The high frequency of this procedure combined by the increasing collective radiation dose in medical exposures, has resulted development tools to maximize the benefit in CT images. This work aimed to establish protocols optimized in abdominal CT through acquisitions parameters and reconstructions techniques based on filters kernels. A sample of patients undergoing abdominal CT in a diagnostic center of Rio de Janeiro was assessed. Had been collected patients information and acquisitions parameters. The phantoms CT image acquisitions were performed by using different voltage values by adjusting the tube current (mAs) to obtain the same value from CTDI{sub vol} patients with normal BMI. Afterwards, the CTDIvol values were reduced by 30%, 50% and 60%. All images were reconstructed with low-contrast filters (A) and standard filters (B). The CTDIvol values for patients with normal BMI were 7% higher than in patients with underweight BMI and 30%, 50% and 60% lower than the overweight, obese I and III patients, respectively. The evaluations of image quality showed that variation of the current (mA) and the reconstruction filters did not affect the Hounsfield values. When the contrast-to-noise ratio (CNR) was normalized to CTDIvol, the protocols acquired with 60% reduction of CTDIvol with 140 kV and 80 kV showed CNR 6% lower than the routine. Modifications of the acquisition parameters did not affect spatial resolution, but the post-processing with B filters reduced the spatial frequency by 16%. With reduced the dose of 30%, lesions in the spleen had the CNR higher than 10% routine protocols with 140 kV acquired and post-processed to filter A. The image post-processing with a filter A with a 80kV voltage provided CNR values equal to the routine for the liver lesions with a 30

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 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.

Techniques for selectively extracting and storing only krypton and xenon in the waste gases that are released from a pressurized water nuclear power reactor are described. The illustrative fluorocarbon absorption system has three separation stages: an initial gas-fluorocarbon absorber, a flash chamber and fractionator for segregating all of the absorbed gases from the loaded absorber stage fluorocarbon (save for the krypton and xenon), and a stripper that receives the partially loaded fluorocarbon liquid directly from the fractionator in order to separate only the krypton and xenon. A molecular sieve filter dries the input process gas, a cartridge type solvent filter is used to remove radiation degradation products from the loaded liquid that flows from the absorber, a cold trap gas drier is provided to remove residual solvent vapor from the separated krypton and xenon, and radiation detectors automatically activate valves to establish safe conditions in the event of an accident or plant failure.

Retoma-se essa causa que acompanha a história da Igreja desde os seus primórdios e que interessa a todos os membros do povo santo de Deus. O texto divide-se em quatro partes. Primeiro, faz-se um apanhado histórico dos anseios de reforma da Igreja, mostrando que, muitas vezes em instâncias subterrâneas, sempre houve o desejo e também ações concretas de renovação. Em seguida, apresenta-se como razão para a reforma da Igreja o anúncio e a realização do Reino de Deus, pelo qual é preciso que a Igreja se volte à concretude humana e histórica de Jesus de Nazaré, pela superação do apego ao poder e às estruturas religiosas. Num terceiro momento, trata-se do critério pelo qual se mede a realização e a veracidade da reforma da Igreja: a santidade de cada fiel e do povo cristão no meio do mundo. Por fim, conclui-se que o caminho para a reforma da Igreja está na escuta dos clamores do Espírito Santo, que fala na própria Igreja e no mundo através do sensus fidei dos fiéis, das Igrejas particulares, dos pobres, das mulheres e das realidades terrestres.

The da Vinci surgical system was developed by Intuitive Surgical Inc. in the United States as an endoscopic surgical device to assist remote control surgeries. In 1998, the Da Vinci system was first used for cardiothoracic procedures. Currently a combination of robot-assisted internal thoracic artery harvest together with coronary artery bypass grafting (CABG) through a mini-incision (ThoraCAB) or totally endoscopic procedures including anastomoses under robotic assistance (TECAB) are being conducted for the treatment of coronary artery diseases. With the recent advances in catheter interventions, hybrid procedures combining catheter intervention with ThoraCAB or TECAB are anticipated in the future.On the other hand, with the decrease in number of coronary artery bypass surgeries, the share of valvular surgeries is expected to increase in the future. Among them, mitral valvuloplasty for mitral regurgitation is anticipated to be conducted mainly by low-invasive procedures, represented by minimally invasive cardiac surgery( MICS) and robot-assisted surgery. Apart from the intrinsic good surgical view, robotic-assisted systems offer additional advantages of the availability of an amplified view and the easy to observe the mitral valve in the physiological position. Thus, robotic surgical surgeries that make complicated procedures easier are expected to accomplish further developments in the future. Furthermore, while the number of surgeries for atrial septal defects has decreased dramatically following the widespread use of Amplatzer septal occluder, robotic surgery may become a good indication for cases in which the Amplatzer device is not indicated. In Japan, clinical trial of the da Vinci robotic system for heart surgeries has been completed. Statutory approval of the da Vinci system for mitral regurgitation and atrial septal defects is anticipated in the next few years.

An illustrative embodiment of the invention discloses a technique for disassembling a nuclear reactor fuel element without destroying the individual fuel pins and other structural components from which the element is assembled. A traveling bridge and trolley that span a water-filled spent fuel storage pool support a strongback. The strongback is under water and provides a working surface on which the spent fuel element is placed for inspection and for the manipulation that is associated with disassembly and assembly. To remove, in a non-destructive manner, the grids that hold the fuel pins in the proper relative positions within the element, bars are inserted through apertures in the grids with the aid of special tools. These bars are rotated to flex the adjacent grid walls and, in this way relax the physical engagement between protruding portions of the grid walls and the associated fuel pins. With the grid structure so flexed to relax the physical grip on the individual fuel pins, these pins can be withdrawn for inspection or replacement as necessary without imposing a need to destroy fuel element components.

The premature well failure and the consequent production losses has caused several problems on managing an oil field.Well teams that deal directly with that problem, particularly operation, well intervention and equipment maintenance are directly impacted. However, teams of well design, procurement, inspection and storage of equipment may also contribute significantly to premature well failure. Based on the tree failure model was structured a methodology that includes dada collecting, processing and correlation from on a specific well intervention. All this information generates analysis and blocking actions for potential causes that led to premature failure, decreasing production losses by increasing the MTTF (Mean Time to Failure). Was developed a new web tool supports the entire process, ensuring information management and failures analysis. Ensuring management decisions with portability and on real-time. (author)

The perspectives of the growing incorporation of no conventional energy sources in the world energy matrix find in Brazil a worthy and promising chart of an adequate planning to the determinants, orientation and warnings based on the world international forums that discuss the energy related issues. To asses the renewable energy potentials, represented by some priority energy sources, as small hydro power, wind power and photovoltaic panels, considering the possibilities of integration or of increasing in isolated systems - partial, or, entirely - is the proposal that is presented. Indices and factors of performance extended - that consider parameters and variables included - is a form, considered, of global analysis of these systems. Studies of the composed load curves, evaluation of the renewability and environmental compatibility are the tools utilized in a first approach, to develop a methodology for the qualification and quantification by means of indicators of the energy supply generated through by multiple sources.

As pesquisas realizadas em torno desta patologia da hemácia, ao longo de quase um século, a partir de 1910, cooperaram para a criação de um novo e importante segmento da ciência, denominado biologia molecular. A descoberta dos polimorfismos da mutação (GAT->GTG no gene que codifica a cadeia beta da hemoglobina, originando diferentes haplótipos da doença, permitiu um melhor e mais amplo conhecimento em torno da heterogeneidade clínica nos pacientes falcêmicos. Analisando a hemoglobina na sua estrutura normal e mutante, sua produção e evolução, pode-se ter um entendimento mais completo da fisiopatologia desta doença e da sua complexidade clínica.

Full Text Available Resumo Ao discorrer sobre o “Futuro do Etnocentrismo”, este artigo parte da premissa de que a globalização, apesar de ter – em muitos casos – diminuído as diferenças entre povos, não tem amenizado os preconceitos e as formas de discriminação que ocorrem em nome dessas diferenças. Ele resgata a importância do antropólogo neste cenário lembrando que a diversidade cultural faz parte da sociedade complexa, remetendo-se não apenas a grupos étnicos ou nacionais bem delimitados, mas também a diferenças de geração, gênero, sexo e classe, entre outros. Neste contexto, a tolerância passiva de modos distantes de vida assim como a aceitação pragmática de nosso próprio paroquialismo são atitudes não somente intelectualmente desonestas mas também moralmente repreensíveis. É no encontro incômodo de subjetividades variantes na sua própria sociedade que o antropólogo define seu lugar.

Technique development to use the da Vince Robotic Surgical System for anterior lumbar interbody fusion at L5-S1 is detailed. A case report is also presented. To evaluate and develop the da Vinci robotic assisted laparoscopic anterior lumbar stand-alone interbody fusion procedure. Anterior lumbar interbody fusion is a common procedure associated with potential morbidity related to the surgical approach. The da Vinci robot provides intra-abdominal dissection and visualization advantages compared with the traditional open and laparoscopic approach. The surgical techniques for approach to the anterior lumbar spine using the da Vinci robot were developed and modified progressively beginning with operative models followed by placement of an interbody fusion cage in the living porcine model. Development continued to progress with placement of fusion cage in a human cadaver, completed first in the laboratory setting and then in the operating room. Finally, the first patient with fusion completed using the da Vinci robot-assisted approach is presented. The anterior transperitoneal approach to the lumbar spine is accomplished with enhanced visualization and dissection capability, with maintenance of pneumoperitoneum using the da Vinci robot. Blood loss is minimal. The visualization inside the disc space and surrounding structures was considered better than current open and laparoscopic techniques. The da Vinci robot Surgical System technique continues to develop and is now described for the transperitoneal approach to the anterior lumbar spine. 4.

nanopillars, the immobilization of CYP2C9 enzymes to those nanopillars, and the utilization of the array to perform conductive probe atomic force microscopy experiments examining the electron transfer process of CYP2C9 in the absence and presence of substrate molecules. Part II. The Src protein has been known to play a role in cancer cell progression for over 30 years. The function of a non-receptor tyrosine kinase such as Src is to relay extracellular signals through intracellular tyrosine phosphorylation. As a tyrosine kinase, Src and the cellular signaling pathways it is involved in play many functional roles in the cell, both in cellular proliferation and in cytoskeletal dynamics, cell adhesion, motility and invasion. Two of the many proteins comprising Src cellular signaling pathways are actin filament associated protein of 110 kDa (AFAP-110) and cortactin. AFAP-110 is a known activator of Src; one mechanism to abrogate the AFAP-110-induced activation of Src is to inhibit their colocalization within the cell. This colocalization is expected to occur when the pleckstrin homology (PH1 and PH2) domains of AFAP-110 are allowed to interact with membrane-bound phospholipids. Cortactin, on the other hand, is a cytosolic protein capable of being phosphorylated on various tyrosine residues, activating it and allowing it to interact with actin. The Src homology 2 (SH2) domain of Src has been shown to be capable of interacting with cortactin, an association which will be probed here. This section of the dissertation will discuss the use of molecular modeling techniques to develop structural models of the AFAP-110 PH1 and PH2 domains and use them to make predictions about how the protein interacts with phospholipids in the plasma membrane and how they might be stabilized to interact with other proteins. Structural models were designed using homology modeling methods, docking programs were used to predict key residues of AFAP-110 involved in binding to phospholipids and mutational

Since the 1950s, scientists have used ionizing radiation to sterilize insects, which are released in nature to mate, but without any progeny. Known as the sterile insect technique (TIE), this method of insect control has traditionally used ionizing radiation to sterilize insects, a technique that does not generate residues, and can act in synergy with the other techniques within integrated pest management. For several years, Brazil has been fighting against the increase of pests, introducing new tactics and techniques within the IPM programs, to overcome the resistance of chemical products, such as: reducing the residues of agrochemicals; For some important crops of our country, we have a wide spectrum of pests occurring from the beginning to the end of the harvest, one of them is the cotton crop and among the key pests of this crop, we have some extremely important caterpillars, among them Heliothis virescens and Helicoverpa armigera These species are morphologically similar, the second being identified a few years ago in Brazil. There are still no studies in Brazil using TIE as an additional tool for Lepidoptera, therefore the purpose of this study was to evaluate the effect of doses of gamma radiation in the different phases of the evolutionary cycle of Heliothis virescens and Helicoverpa armigera, as well as to evaluate the sterility in generation P And the ability of insects to irradiate with non-irradiated insects. The pupal phase presented the best result because 75 Gy achieved sterility in Heliothis virecens and 100 Gy sterilized Helicoverpa armigera, therefore it contemplated the phase and dose chosen to evaluate the competition between the irradiated insects and the normal insects of both species. Both Heliothis virecens and Helicoverpa armigera presented a satisfactory result, as the irradiated insects managed to significantly reduce the viability of the eggs in a ratio of 9: 1: 1. (author)

Full Text Available The objective of this work was to determine the total carbohydrates fractions and to estimate the digestion rate of non-fibrous carbohydrates of agroindustrial byproducts by using the gas production technique. The agroindustrial byproducts evaluated were the following: cashew, passion fruit, pineapple, barbados cherry, annatto and melon, and each sample was incubated in quadruplicate. After mixing all contents thoroughly, the bottles were placed in an incubator at 39ºC, and connecting the lid of each bottle to a pressure sensitive switch, a solenoid valve and a vent stem connector. Gas pressure measurements were made at 0, 3, 6, 12, 15, 18, 22, 26, 30, 34, 40, 48, 60, 72, 96 e 120 hours post-inoculation. Blanks and an internal standard were included to enable adjustments in variation among readings. There was a high variation in nutritional composition of agroindustry byproducts, that cashew and annato presented the highest protein contents (159.3 and 135.3 g/kg of dry matter, respectively. Mellon and cashew presented the lowest values of total gas production (9.60 and 12.85 mL, respectively; and annato, pineapple and passion fruit presented highest gas volume (32.80; 28.16 and 22.54 mL, respectively, being the greatest percentages of phases from B2 fraction (64.27; 81.25 and 67.49%, respectively. Among the byproducts, pineapple and annatto stand out for the highest contribution of fibrous carbohydrate for total gas production, being B2 the main energy source for microbial growth, which is degraded at a slower rate than non-fibrous carbohydrate.Os objetivos deste trabalho foram determinar as frações de carboidratos totais e estimar a taxa de digestão dos carboidratos não-fibrosos de subprodutos agroindustriais, utilizando a técnica de produção de gás.

20. O panorama das Drogas no México: da margem da sociedade ao centro da cultura

2013-12-01

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.

5. da Vinci decoded: does da Vinci stereopsis rely on disparity?

Science.gov (United States)

Tsirlin, Inna; Wilcox, Laurie M; Allison, Robert S

2012-11-01

In conventional stereopsis, the depth between two objects is computed based on the retinal disparity in the position of matching points in the two eyes. When an object is occluded by another object in the scene, so that it is visible only in one eye, its retinal disparity cannot be computed. Nakayama and Shimojo (1990) found that a precept of quantitative depth between the two objects could still be established for such stimuli and proposed that this precept is based on the constraints imposed by occlusion geometry. They named this and other occlusion-based depth phenomena "da Vinci stereopsis." Subsequent research found quantitative depth based on occlusion geometry in several other classes of stimuli grouped under the term da Vinci stereopsis. However, Nakayama and Shimojo's findings were later brought into question by Gillam, Cook, and Blackburn (2003), who suggested that quantitative depth in their stimuli was perceived based on conventional disparity. In order to understand whether da Vinci stereopsis relies on one type of mechanism or whether its function is stimulus dependent we examine the nature and source of depth in the class of stimuli used by Nakayama and Shimojo (1990). We use three different psychophysical and computational methods to show that the most likely source for depth in these stimuli is occlusion geometry. Based on these experiments and previous data we discuss the potential mechanisms responsible for processing depth from monocular features in da Vinci stereopsis.

Objetivou-se avaliar o efeito da urina de vaca no estado nutricional da alface. O experimento foi constituído de 12 tratamentos, esquema de parcelas subdivididas, em blocos ao acaso, com quatro repetições. Nas parcelas foram alocadas as vias de aplicação (solo ou foliar e nas subparcelas as concentrações das soluções (0,00; 0,25; 0,50; 0,75; 1,00 e 1,25% v/v. Aplicou-se 60 mL de solução/planta, divididos em cinco aplicações de 5; 5; 10; 20 e 20 mL/planta, aos 7, 14, 21, 28 e 35 após o transplante, respectivamente. Durante o ciclo avaliou-se o índice SPAD e na colheita a massa da matéria seca de cabeça (MSCA e os teores de N, P, K, Ca, Mg, S, Na, Zn, Fe, Mn, Cu e B na matéria seca das folhas (MSF, caule (MSC e raízes (MSR. Em ambas as vias de aplicação o índice SPAD apresentou incremento linear às concentrações e resposta quadrática ao longo do tempo. A MSCA teve comportamento linear às concentrações, com aumento de 25,9 e 35,4% nas aplicações via foliar e solo, respectivamente. Não houve efeito de concentrações sobre teores de nutrientes na MSF e MSC. Na MSR, via solo, os teores de P e K apresentaram pontos de máximo enquanto Fe e Mn de mínimo; o Na apresentou incremento linear às concentrações via foliar. Os efeitos da urina sobre o crescimento da alface provavelmente são devidos a fatores outros que não somente a quantidade de nutrientes veiculados nas soluções.

Full Text Available Contamination of fresh milk with Staphylococcus aureus was assessed comparatively through routine phenotypic (coagulase tube test and coagulase slide test and genotypic (PCR screening of 128 S. aureus strains isolated from 555 milk samples. These samples were collected from 362 cows with subclinical mastitis, hosted in different dairy herds at various locations of the Northern and Northeastern rural areas of the State of Rio de Janeiro, 39.7% of which were CMT-positive. All S. aureus isolates tested positive for the presence of the coagulase gene by PCR and the isolates could be grouped into four distinct classes according to the size of the PCR product. The strains also yielded variable results when assayed with coagulase test. Taken together, these data indicate the existence of extensive polymorphism at the coagulase gene locus in the genus Staphylococcus and exemplifies the extent of molecular and phenotypic heterogeneity associated with the strains circulating in rural herds.Quinhentas e cinqüenta e cinco amostras de leite, provenientes de 362 vacas com mastite subclínica em diferentes propriedades rurais do Estado do Rio de Janeiro, Brasil, de 1995 a 1997, foram submetidas ao teste "Califórnia Mastitis Test" (CMT. 39,7% das amostras foram positivas, das quais foram isoladas 128 cepas de Staphylococcus aureus. Todas as cepas isoladas foram positivas para o gene da coagulase utilizando a técnica de PCR, todavia, resultados de coagulase através das técnicas em tubo e "coagulase slide test" foram variáveis. Após a amplificação do gen de coagulase através da técnica de PCR utilizando iniciadores específicos para o referido gen, fragmentos com diferentes pesos moleculares foram vistos através de análise em gel de agarose, sugerindo a ocorrência de polimorfismo genético. O estudo também sugere a ocorrência de diferentes cepas da bactéria atuando nos rebanhos leiteiros causando mastite bovina.

2006-04-01

Full Text Available No presente artigo, realiza-se uma descrição etnográfica da prática da tatuagem na contemporaneidade, a partir de uma perspectiva que prioriza as noções da prática, das interações e das experiências vividas durante o processo de ser tatuado. A reflexão tenta reconstruir uma visão total da prática da tatuagem que abrange o mundo subjetivo e as dinâmicas sociais como partes constitutivas desse ato. Entre as idéias conclusivas estão, de um lado, o surgimento de uma nova normalidade estética e vivencial no seio da sociedade ocidental e, de outro, a configuração de uma nova subjetividade, a dos "tatuados", como um processo interativo, inovador, emotivo e reflexivo, em que o corpo se converte em uma forma de expressão e construção do sujeito.This article provides a descriptive account of contemporary tattooing, based on a perspective that prioritizes the notion of practice, as well as the interactions and experiences involved in the process of being tattooed. The analysis attempts to rebuild a holistic view of tattooing, combining subjective processes and social dynamics as equally constitutive parts of this activity. Among the conclusions reached are: (a the emergence of tattooing as a new aesthetic norm and a lived experience at the heart of the western society; and (b the configuration of a new subjectivity, the ‘tattooed,’ as an interactive, innovative, emotional and reflexive process in which the body is converted into a form of expressing and constructing the subject.

Full Text Available As grandes cidades estão doentes. Seus sintomas: a quebra da sociabilidade e a irrupção rotineira da violência. Diante disso, ecoa na sociedade um clamor por ordem. No mesmo momento em que a polícia põe a tropa na rua, os literatos criam personagens que dão voz à sensação crescente de que a cidade está deixando de ser uma referência à constituição das identidades urbanas. É a partir da literatura, em especial da obra do escritor Rubem Fonseca, que iremos perscrutar as possibilidades apresentadas pela cidade para o convívio humano.The great cities are sick. Its indications: the sociability in addition and the routine irruption of the violence. Ahead of this, a outcry for order echoes in the society. At the same moment where the policy goes to the street, the writers create personages who give voice to the increasing sensation of that the city is leaving of being a reference to the constitution of the urban identities. It is from literature, in special of the writer Rubem Fonseca, that we will go to investigate the possibilities presented for the city for the human conviviality.

Full Text Available 14 specimens of Nile’s tilapia were analyzed cytogenetically, Oreochromis niloticus, that belong to the stock of fish breeding from the Freshwater Aquaculture Station of the Londrina State University in the Paraná, Brazil. All specimens presented the same disploid number of 44 chromosomes. The NORs were observed in four chromosomes with marks in terminal position of the short arm and the hybridization “in situ” (FISH with probe of 18 S also evidenced the presence of two pairs of chromosomes containing ribbosomic cistrons. The treatment with the fluochromes CMA3 and DAPI, respectively, didn’t show shinning bands in any chromosome of the complement. The band C (CBG evidenced regions of heterochromatin distributed on several chromosomes in the centromeric regions, being observed some marks in telomeric regions, mainly on the biggest pair of chromosomes of the complement, a pair presented itself almost totally heterochromatic. The obtained results are in accordance with the data found in literature, nevertheless when the C bands and NORs were analyzed, were evidenced some differences that apparently characterized the local fish population of the Londrina State University. Key words: Cytogenetics, Oreochromis niloticus, NORs, CMA3, DAPI, fish, heterochromatin.Foram analisados citogeneticamente 14 indivíduos de tilápia do Nilo, Oreochromis niloticus que fazem parte do estoque de reposição de reprodutores da Estação de Piscicultura da Universidade Estadual de Londrina, Paraná, Brasil.

Full Text Available This paper intends to introduce the three issues of Principia which will appear in a sequel honoring Newton da Costa’s 80th birthday. Instead of presenting the papers one by one, as it is common in presentations such as this one, we have left the papers speak by themselves, and instead we have preferred to present to the Brazilian readers, specialty to our students, some aspects of Newton da Costa’s conception of science and of the scientific activity, grounded on the concept of quasi-truth, which he contributed to develop in a rigorous way. Da Costa is known as one of the founding fathers of paraconsistent logic, but his contributions go also to the foundations of physics, theoretical computation, model theory, algebraic logic, lattice theory, applications of non-classical logics to law and technology, etc. But perhaps his main contribution was to provide a basis for the birth of a school of logic in our country (Brazil, serving as teacher and inspiring new researchers for generations. It is a pleasure to have had so enthusiastic acceptation from the editors of Principia to organize these volumes. I would like to thank the contributors and the editors of Principia, specially Prof. Cezar Mortari for his help in organizing the issue.

Full Text Available A identificação dos montantes de chuva para uma região corrobora para a gestão eficiente das politicas públicas e o desenvolvimento social, econômico e ambiental dos centros urbanos.  A mesorregião metropolitana de Belém detém a maior concentração populacional e urbana da Amazônia Oriental, apresentando elevados índices pluviômetros durante todo o ano. Neste contexto o presente trabalho visa identificar a distribuição temporal e espacial da precipitação na mesorregião metropolitana de Belém e associa-la aos principais sistemas precipitantes que atuam na região. Para isto se utilizou o sensoriamento remoto por meio da técnica do CPC MORPHing technique (CMORPH com resolução temporal de 30 min e espacial de 8/8 km. A partir da técnica empregada foram gerados mapas da distribuição têmporo-espacial da chuva com as médias mensais para os dozes meses do ano, decorrentes dos acumulados do período de Jan/2000 a Dez/2010. Os resultados mostram que há uma grande variação temporal e espacial da chuva na mesorregião evidenciando de modo satisfatório a sazonalidade regional da precipitação, com altos índices durante o período chuvoso e baixos índices no período menos chuvoso. Trabalhos que visem à interdisciplinaridade podem contribuir de forma eficaz para estruturação das ciências ambientais e para a tomada de decisões.

5. Thorascopic resection of an apical paraspinal schwannoma using the da Vinci surgical system.

Finley, David; Sherman, Jonathan H; Avila, Edward; Bilsky, Mark

2014-01-01

Posterior mediastinal neurogenic tumors have traditionally been resected via an open posterolateral thoracotomy. Video-assisted thorascopic surgery has emerged as an alternative technique allowing for improved morbidity with decreased blood loss, less postoperative pain, and a shorter recovery period, among others. The da Vinci surgical system, as first described for urologic procedures, has recently been reported for lung lobectomy. This technique provides the advantages of instrumentation with 6 degrees of freedom, stable operating arms, and improved visualization with the three-dimensional high-definition camera. We describe the technique for thorascopic resection of an apical paraspinal schwannoma of the T1 nerve root with the da Vinci surgical system. This technique used a specialized intraoperative neuromonitoring probe for free-running electromyography (EMG) and triggered EMG. We demonstrate successful resection of a posterior paraspinal schwannoma with the da Vinci surgical system while preserving neurologic function. The patient displayed stable intraoperative monitoring of the T1 nerve root and full intrinsic hand strength postoperatively. The technique described in this article introduces robotic system accuracy and precludes the need for an open thoracotomy. In addition, this approach demonstrates the ability of the da Vinci surgical system to safely dissect tumors from their neural attachments and is applicable to other such lesions of similar size and location.

Moser, H.

1976-01-01

The nuclear techniques used in hydrology are usually tracer techniques based on the use of nuclides either intentionally introduced into, or naturally present in the water. The low concentrations of these nuclides, which must be detected in groundwater and surface water, require special measurement techniques for the concentrations of radioactive or of stable nuclides. The nuclear techniques can be used most fruitfully in conjunction with conventional methods for the solution of problems in the areas of hydrology, hydrogeology and glacier hydrology. Nuclear techniques are used in practice in the areas of prospecting for water, environment protection and engineering hydrogeology. (orig.) [de

With the development of laser, remote inspection techniques using laser have been growing on. The inspection and measurement techniques by pulse holography are well-established technique for precise measurement, and widely used in various fields of industry now. In nuclear industry, this technology is practically used because holographic inspection is remote, noncontact, and precise measurement technique. In relation to remote inspection technology in nuclear industry, state-of-the art of pulse HNDT (Holographic non-destructive testing) and holographic measurement techniques are examined. First of all, the fundamental principles as well as practical problems for applications are briefly described. The fields of pulse holography have been divided into the HNDT, flow visualization and distribution study, and other application techniques. Additionally holographic particle study, bubble chamber holography, and applications to other visualization techniques are described. Lastly, the current status for the researches and applications of pulse holography to nuclear industry which are carried out actively in Europe and USA, is described. (Author)

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.

Our recent studies have shown that the difference in basal pain sensitivity to mechanical and thermal stimulation between Dark-Agouti (DA) rats and a novel congenic DA.1U rats is major histocompatibility complex (MHC) genes dependent. In the present study, we further used DA and DA.1U rats to investigate the role of MHC genes in formalin-induced pain model by behavioral, electrophysiological and immunohistochemical methods. Behavioral results showed biphasic nociceptive behaviors increased significantly following the intraplantar injection of formalin in the hindpaw of DA and DA.1U rats. The main nociceptive behaviors were lifting and licking, especially in DA rats (PDA rats were significantly higher than those in DA.1U rats in both phases of the formalin test (PDA rats was significantly higher than that of DA.1U rats (PDA was greater than that in DA.1U rats (PDA rats was significantly higher than that in DA.1U rats in the respective experimental group (PDA and DA.1U rats exhibited nociceptive responses in formalin-induced pain model and DA rats were more sensitive to noxious chemical stimulus than DA.1U rats, indicating that MHC genes might contribute to the difference in pain sensitivity.

This paper presents the methodology and results obtained with radioactive tracer techniques as applied to study sea-bottom sediments movements off a stretch of the southern coast of Sao Paulo State, Brazil, namely Praia do Una. Three injections of ground glass containing Iridium-192 were made and the behaviour of this material was tracked by special detection techniques, as it was acted upon by hydrodynamic agents, in two distinct periods of the year of 1982 (summer and winter). Measurement of hydrodynamic parameters was conducted simultaneously with tracer experiments. From the experiments with radioactive tracers, combined with other conventional studies, qualitative and quantitative conclusions could be drawn, as follows: waves are the prevailing agents in moving bottom sediments; during summer time, onshore and alongshore transport can be identified; during winter time, offshore and alongshore transport are present; for summer conditions, Massif transport rate was estimated to be 150 kg m{sup -1} day {sup -1}.

Given the new methodology introduced in the shielding calculation due to recent modulated techniques in radiotherapy treatment, it became necessary to evaluate the impact of changes in the accelerator routine using such techniques. Based on a group of 30 patients from the National Cancer Institute (INCA) the workload multiplier factors for intensity modulated radiotherapy (IMRT factor) and for RapidArc™ (RA factor) were established. Four different routines in a 6 MV generic accelerator were proposed to estimate the impact of these modified workloads in the building cost of the secondary barriers. The results indicate that if 50% of patients are treating with IMRT, the secondary barrier becomes 14,1% more expensive than the barrier calculated for conformal treatments exclusive. While RA, in the same proportion, leads to a barrier only 3,7% more expensive. Showing that RA can, while reducing treatment time, increase the proportion of patients treated with modulation technique, without increasing the cost of the barrier, when compared with IMRT.

Full Text Available O artigo apresenta algumas das principais reflexões de Freud sobre os temas da guerra e do pacifismo.  Partindo do texto “Da guerra e morte. Temas da atualidade”, escrito  durante a Primeira Guerra Mundial,  a autora mostra de que modo  Freud estabeleceu a incursão da psicanálise no campo da política e de que modo esta conexão exige do analista  manter sua escuta voltada  para a singularidade contemporânea.  Conclui que  em relação a dimensão catastrófica do psiquismo, que podemos observar hoje, por exemplo, na passagem ao ato violento; na delinqüência; na toxicomania; no totalitarismo que se coloca acima da lei e no fundamentalismo como  instrumento da lei divina etc,  importa salientar que a existência desses  novos modos de expressão dos sintomas, põe à prova o devir da psicanálise.  Lança, por fim, a aposta: o futuro da psicanálise depende da responsabilidade do analista em manter seu trabalho voltado à dinâmica psíquica do sujeito, individual ou coletivo, sem abrir mão do rigor dos conceitos freudianos.

8. Quality Attribute Techniques Framework

Science.gov (United States)

Chiam, Yin Kia; Zhu, Liming; Staples, Mark

The quality of software is achieved during its development. Development teams use various techniques to investigate, evaluate and control potential quality problems in their systems. These “Quality Attribute Techniques” target specific product qualities such as safety or security. This paper proposes a framework to capture important characteristics of these techniques. The framework is intended to support process tailoring, by facilitating the selection of techniques for inclusion into process models that target specific product qualities. We use risk management as a theory to accommodate techniques for many product qualities and lifecycle phases. Safety techniques have motivated the framework, and safety and performance techniques have been used to evaluate the framework. The evaluation demonstrates the ability of quality risk management to cover the development lifecycle and to accommodate two different product qualities. We identify advantages and limitations of the framework, and discuss future research on the framework.

Ceria containing rare-earth ceramics are potential candidates for application in intermediate-temperature solid oxide fuel cells. One of the main problems related to these ceramic materials is their relatively low sinterability. In this work, the effects of Ca and Li additions on densification and electrical conductivity of 10 mol% gadolinia-doped ceria was investigated. Ceramic compositions containing 1.5 mol% Ca or Li were prepared by the oxalate coprecipitation technique. Results of sintered density and electrical conductivity were compared to those of ceramic samples obtained by solid state reactions showing the effects of the synthesis method on densification and total electrical conductivity of the sintered materials.

Full Text Available Resumo A cultura audiovisual vem cada vez mais ganhando espaço, e os avanços tecnológicos contribuem, vertiginosamente, para o seu desenvolvimento e sua abrangência. Assim, este estudo tem como temática a cultura audiovisual, e como objetivo de pesquisa, discutir a importância das imagens na televisão. Para tanto, selecionamos um exemplo de propaganda televisiva observada no ano de 2006, que inspirou uma reflexão crítica sobre a importância das linguagens híbridas na televisão, ilustrando a interferência dessas na produção do sentido na mensagem televisiva. Como referencial teórico e metodológico, utilizamos as concepções de imagem e linguagens híbridas de Lúcia Santaella. A partir da análise da propaganda ora proposta concluímos que sua constituição é mais icônica do que de verbal, mas que se insere numa concepção dialógica, constituindo-se, portanto, por meio de um processo criativo de produção de significados.

This present work allowed the study of deformation and fracture micro mechanisms of titanium alloy Ti-6Al-4V, used commercially for the manufacture of metallic biomaterials. The techniques employed for the analysis of the material under study were: scanning electron microscopy (SEM), transmission electron microscopy (TEM) and X-ray diffraction (XRD). The study of the influence and behavior of the phases present in titanium alloys is important to evaluate the behavior of cracks in titanium alloys with high mechanical strength, which have fine alpha ({alpha}), beta ({beta}) and ({alpha}{+-}{beta}) microstructure, linking the presence of the phases with the strength of the material. The evaluation in situ of deformation and fracture micro mechanisms were performed by TEM and was also a study of phase transformations during cooling in titanium alloys, using the techniques of bright field, dark field and diffraction of electrons in the selected area. After heat treatment differences were observed between the amount of in relation to the original microstructure of the {beta} and {alpha} phases material for different conditions used in heat treatment applied to the alloy. The presence of lamellar microstructure formed during cooling in the {beta} field was observed, promoting the conversion of part of the secondary alpha structure in {beta} phase, which was trapped between the lamellar of alpha.

Full Text Available Paul C Montgomery, Audrey Leong-Hoi Laboratoire des Sciences de l'Ingénieur, de l'Informatique et de l'Imagerie (ICube, Unistra-CNRS, Strasbourg, France Abstract: To face the challenges of modern health care, new imaging techniques with subcellular resolution or detection over wide fields are required. Far field optical nanoscopy presents many new solutions, providing high resolution or detection at high speed. We present a new classification scheme to help appreciate the growing number of optical nanoscopy techniques. We underline an important distinction between superresolution techniques that provide improved resolving power and nanodetection techniques for characterizing unresolved nanostructures. Some of the emerging techniques within these two categories are highlighted with applications in biophysics and medicine. Recent techniques employing wider angle imaging by digital holography and scattering lens microscopy allow superresolution to be achieved for subcellular and even in vivo, imaging without labeling. Nanodetection techniques are divided into four subcategories using contrast, phase, deconvolution, and nanomarkers. Contrast enhancement is illustrated by means of a polarized light-based technique and with strobed phase-contrast microscopy to reveal nanostructures. Very high sensitivity phase measurement using interference microscopy is shown to provide nanometric surface roughness measurement or to reveal internal nanometric structures. Finally, the use of nanomarkers is illustrated with stochastic fluorescence microscopy for mapping intracellular structures. We also present some of the future perspectives of optical nanoscopy.

Low-bandgap near-infrared polymers are usually synthesized using the common donor-acceptor (D-A) approach. However, recently polymer chemists are introducing more complex chemical concepts for better fine tuning of their optoelectronic properties. Usually these studies are limited to one or two polymer examples in each case study so far, though. In this study, the dependence of optoelectronic and macroscopic (device performance) properties in a series of six new D-A 1 -D-A 2 low bandgap semiconducting polymers is reported for the first time. Correlation between the chemical structure of single-component polymer films and their optoelectronic properties has been achieved in terms of absorption maxima, optical bandgap, ionization potential, and electron affinity. Preliminary organic photovoltaic results based on blends of the D-A 1 -D-A 2 polymers as the electron donor mixed with the fullerene derivative [6,6]-phenyl-C 71 -butyric acid methyl ester demonstrate power conversion efficiencies close to 4% with short-circuit current densities (J sc ) of around 11 mA cm -2 , high fill factors up to 0.70, and high open-circuit voltages (V oc s) of 0.70 V. All the devices are fabricated in an inverted architecture with the photoactive layer processed in air with doctor blade technique, showing the compatibility with roll-to-roll large-scale manufacturing processes. © 2017 WILEY-VCH Verlag GmbH & Co.

The bystander effect refers to biological responses detected in cells not directly irradiated but influenced, somehow, by signals transmitted from neighboring irradiated cells. These biological responses include sister chromatid exchange, mutations, micronucleus formation, chromosomal aberrations, carcinogenesis, apoptosis and necrosis. Although its existence is unquestionable, the mechanisms involved on triggering the bystander effect are not yet completely elucidated. Previous studies have shown that the bystander effect depends on a large variety of parameters including the radiation dose, the dose rate, the type of radiation and type of cells or tissue. This study aims to confirm the technique previously used in the literature in human cell lines for the bystander effect verification. The results suggest that the working conditions adopted by the group show technical efficiency and enables the reproduction of the bystander effect. (author)

Minimal invasive surgery has proven its advantages over open surgeries in the perioperative period. Food and Drug Administration approved da Vinci robot in 2000. The latest version, da Vinci Xi system has a mobile tower-based robot with several modifications to improve the functionality, versatility, and operative ease. None of the centers have reported exclusively on hepatobiliary oncology using the da Vinci Xi system. We report our initial experience. To study the feasibility, advantages, and discuss the operative technique of da Vinci Xi system in hepatobiliary oncology. Data were analyzed retrospectively from a prospectively maintained database from June 2015 to October 2016. Twenty-five patients with suspected or proven hepatobiliary malignancies were operated. Total robotic technique using da Vinci Xi system was used. Demographic details and perioperative outcomes were noted. Of the 25 surgeries, 14 patients had a suspected gallbladder malignancy, 11 patients had primary or metastatic liver tumor. Median age was 53 years. The average duration of surgery was 225 min with a median blood loss 150 ml. The median postoperative stay was 4 days. The median nodal yield for radical cholecystectomy was seven. Five patients required conversion. Two of these developed postoperative morbidity. Robotic surgery for hepatobiliary oncology is feasible and can be performed safely in experienced hands. Increasing experience in this field may equal or even prove advantageous over conventional or laparoscopic approach in future. A cautious approach with judicious patient selection is the key to establishing robotic surgery as a standard surgical approach.

10. Disagreements around techniques

International Nuclear Information System (INIS)

Sachsse, H.

The modern man lives in disagreement with its techniques. Technical progress is the foundation of its material and spiritual existence, but he does not like it. Specialization, difficult understanding of the technical procedures and the price that has to be paid for technical progress, have led to a deep-going enstrangement. Therefore the question: What kind of human function has our technique. It is understood as an extension and perfection of our bodily organs, in order to increase our ability to see and to hear enormously, and to intervene formatively in the existing reality. Technique is therefore an instrument of comprehensive self-realization of man. (orig./GL) [de

Chromatography is an important biophysical technique that enables the separation, identification, and purification of the components of a mixture for qualitative and quantitative analysis. Proteins can be purified based on characteristics such as size and shape, total charge, hydrophobic groups present on the surface, and binding capacity with the stationary phase. Four separation techniques based on molecular characteristics and interaction type use mechanisms of ion exchange, surface adsorption, partition, and size exclusion. Other chromatography techniques are based on the stationary bed, including column, thin layer, and paper chromatography. Column chromatography is one of the most common methods of protein purification. PMID:28058406

The development of several new analytical techniques for use in clinical diagnosis and biomedical research is reported. These include: high-resolution liquid chromatographic systems for the early detection of pathological molecular constituents in physiologic body fluids; gradient elution chromatography for the analysis of protein-bound carbohydrates in blood serum samples, with emphasis on changes in sera from breast cancer patients; electrophoretic separation techniques coupled with staining of specific proteins in cellular isoenzymes for the monitoring of genetic mutations and abnormal molecular constituents in blood samples; and the development of a centrifugal elution chromatographic technique for the assay of specific proteins and immunoglobulins in human blood serum samples

Algebraic reconstruction techniques (ART) are iterative procedures for reconstructing objects from their projections. It is proven that ART can be computationally efficient by carefully arranging the order in which the collected data are accessed during the reconstruction procedure and adaptively adjusting the relaxation parameters. In this paper, an adaptive algebraic reconstruction technique (AART), which adopts the same projection access scheme in multilevel scheme algebraic reconstruction technique (MLS-ART), is proposed. By introducing adaptive adjustment of the relaxation parameters during the reconstruction procedure, one-iteration AART can produce reconstructions with better quality, in comparison with one-iteration MLS-ART. Furthermore, AART outperforms MLS-ART with improved computational efficiency
