    This paper from the perspective of the Neighbor cellular space, Proposed a new urban space expansion model based on a new multi-objective gray decision and CA. The model solved the traditional cellular automata conversion rules is difficult to meet the needs of the inner space-time analysis of urban changes and to overcome the problem of uncertainty in the combination of urban drivers and urban cellular automata. At the same time, the study takes Pidu District as a research area and carries out urban spatial simulation prediction and analysis, and draws the following conclusions: (1) The design idea of the urban spatial expansion model proposed in this paper is that the urban driving factor and the neighborhood function are tightly coupled by the multi-objective grey decision method based on geographical conditions. The simulation results show that the simulation error of urban spatial expansion is less than 5.27 %. The Kappa coefficient is 0.84. It shows that the model can better capture the inner transformation mechanism of the city. (2) We made a simulation prediction for Pidu District of Chengdu by discussing Pidu District of Chengdu as a system instance.In this way, we analyzed the urban growth tendency of this area.presenting a contiguous increasing mode, which is called "urban intensive development". This expansion mode accorded with sustainable development theory and the ecological urbanization design theory.

    Full Text Available En la memoria colectiva de los europeos, la Guerra Civil española ocupa un lugar destacado. El lenguaje cinematográfico y la representación fílmica de esa contienda forman un ámbito relevante en el que estudiar algunos rasgos de la matriz cultural europea. El presente trabajo selecciona parte de la producción fílmica de propaganda del gobierno republicano, en concreto los filmes de montaje supervisados por Luis Buñuel. Al inicio de la contienda el cineasta aragonés vuelve a París siguiendo las indicaciones del Ministerio español de Asuntos Exteriores para colaborar, en la embajada española en la capital francesa, en diversas labores de contraespionaje y propaganda. Entre ellas y principalmente, Buñuel se ocupa de reunir, organizar y montar diverso material fílmico prorrepublicano. A diferencia de otras producciones proyectadas en España, los filmes parisinos de propaganda republicana se caracterizaron, en términos generales, por estar dirigidas a públicos de distintos países europeos con el objetivo de romper la doctrina de no intervención en el conflicto y se inscriben dentro de las teorías y concepción de Buñuel sobre el documentalismo filmado, donde primaba lo reflexivo y los recursos psicológicos que motivaran a la acción o a la toma de conciencia individual. El presente texto se ocupa, en ese contexto, de la descripción y el análisis del lenguaje y las prácticas fílmicas en esos años. De todas ellas, el filme «España, 1936» (1937, es a la vez un ejemplo emblemático y singular.The Spanish Civil War occupies an important place in the European collective memory. The film language and depiction of that conflict provide an important platform from which to study certain features of the European cultural matrix.

    Full Text Available Civilité et barbarie vont de pair. C’est ce que nous suggèrent le cinéaste espagnol Luis Buñuel et la dramaturge autrichienne Elfriede Jelinek dans leurs versions postmodernes de l’Ange exterminateur. En se réclamant de l’allégorie biblique de l’ange mortifère (Todesengel, ils esquissent une société en rupture avec la conception traditionnelle. Ce portrait d’une société que l’on pourrait qualifier de « post-civilisée » invite à repenser, à partir des deux œuvres fictionnelles, le conflit social qui résulte d’une remise en question radicale des normes sociales de l’Occident.Zivilisiertheit und Barbarei bilden einen gemeinsamen Nexus. Dies suggerieren der spanische Regisseur Luis Buñuel und die österreichische Autorin Elfriede Jelinek in ihren postmodernen Fassungen des Würgeengels. Auf die biblische Figur des Todesengels rekurrierend skizzieren sie eine Gesellschaft, die deutlich mit der traditionellen Selbstauffassung bricht. Das Porträt jener Gesellschaft, die man als „post-zivilisiert“ bezeichnen könnte, lädt dazu ein, den sozialen Konflikt, der sich aus der radikalen Infragestellung der westlichen Gesellschaftsnormen ergibt, anhand der zwei fiktionalen Werke zu überdenken.

    Full Text Available Mercedes Pinto’s itinerary took her from the Canary Islands, where she was born, to Mexico, after a passage through Uruguay. She first met success through her writings and cultural activities, and was then forgotten. However, her book –published in Montevideo in 1926– was adapted for the cinema by Luis Buñuel in 1952, and the film gave new life to this autobiographical “novel” He. If self-fiction prevails in the literary work, with the clear commitment of a feminist who takes a stand in favour of freedom –the freedom to divorce in that case–, in Buñuel’s Mexican film the study of the clinical case of paranoia acquires a new form of complexity. The attack on a parasitic bourgeoisie is united to the subversion of the melodramatic genre, with a false happy end which distorts established codes and lets the principle of doubt impose itself. In the same way the exploration of sexual roles, heir to the surrealistic trend, is devoid of any manichean simplification and stands out as a fascinating object for any hermeneutic approach.Mercedes Pinto, cuya trayectoria se desarrolló desde Canarias, su tierra de nacimiento, hasta México, pasando por Uruguay, conoció el éxito por sus escritos y actividades culturales y luego quedó sumida en el olvido. Sin embargo, la adaptación de su “novela” autobiográfica Él (Montevideo, 1926 a la gran pantalla por Luis Buñuel en 1952, le deparó otra vida al libro. Si en la obra literaria prevalece la autoficción y su claro compromiso feminista a favor del divorcio, adquiere nueva complejidad en la película mexicana de Buñuel el estudio del caso clínico de la paranoia. Al ataque a una burguesía parasitaria se une una subversión del género del melodrama, cuyo falso final feliz pervierte los códigos establecidos, dejando que se imponga el principio de duda. Asimismo, la exploración de los roles sexuales, heredera de la corriente surrealista, rehúye toda simplificación maniquea y se

    Full Text Available En este artículo reflexionamos sobre la relación entre acción comunitaria y transformación social en el ámbito de Psicología Comunitaria a partir del análisis de la experiencia del Centro Social Comunitario Luis Buñuel, iniciativa puesta en marcha por vecinas y vecinos en la ciudad de Zaragoza después de la irrupción del movimiento 15M en el contexto español en 2011. Los conceptos de participación y comunidad son discutidos a partir del diálogo entre los significados y prácticas desplegadas por esta iniciativa ciudadana y algunas perspectivas emergentes en el campo de la intervención social. Los debates planteados buscan abrir nuevos horizontes en la conceptualización de los procesos de intervención social explorando las nociones de articulación, involucración, lo cotidiano, lo común, la interdependencia y los cuidados. Se concluye con una serie con consideraciones relacionadas con las posibilidades que abre pensar la intervención social a partir de procesos comunitarios articulados desde la ciudadanía.

    Design features are considered of units for nondestructive testing of spent fUel elements and fuel assemblies (FA) in the storage pools of NPP with the PWR and BWR reactors. Units for remote viewing control of fuel element cans and FA, for direct measurements of their geometrical dimensions, for FA leak-testing, fuel element can nondestructive testing and gamma scanning, for measuring gaseous fission product pressure and fuel element free volume are described along with units for complex checking of fuel element and FA parameters. The units for nondestructive testing of spent fuel elements and EA are shown to differ both in their designs and a number of checked parameters of fuel elements and FA. The remote viewing and those for measuring the basic FA parameters are most generally employed. Units for complex testing of multiple fuel element parameters, designed in the last few years, are intended for operation with FA disassembled partially or fully and are characteristic of a high degree of computer measuring automation both for the process control and data processing

    2011-08-01

    Undifferentiated (embryonal) liver sarcoma (UELS) is a rare tumor that typically occurs in children. The association of UELS with neoplasm other than mesenchymal liver hamartoma is exceedingly rare. The aim of the study was to report 3 cases of UELS, 2 of them being interesting because of their association with another neoplasm, vaginal embryonal rhabdomyosarcoma in a teenage girl and B-acute lymphoblastic leukemia in a middle-aged woman. Besides, one of our cases of UELS, in a 58-year-old woman, is an extremely rare presentation of such a tumor in a middle-aged adult. The patient's clinical features, therapy, and pathologic results were reviewed; immunohistochemical analysis and, in 2 cases, electron microscopy were performed. In this study, all 3 patients were females aged 13, 13, and 58 years. Histopathologic evaluation of resected liver tumors confirmed the diagnosis of UELS in all of them. In 2 of the cases, metachronous occurrence of UELS with vaginal embryonal rhabdomyosarcoma in a teenage girl and B-acute lymphoblastic leukemia in a middle-aged woman is described. Careful clinical analysis, histologic studies, and immunohistochemistry are mandatory to distinguish UELS from other hepatic malignancies with similar or overlapping features and to exclude the possibility of other tumors that may be considered in the differential diagnosis. The association of UELS with another neoplasm is exceedingly rare. Copyright © 2011 Elsevier Inc. All rights reserved.

  9. Studies in using a universal exchange and inference language for evidence based medicine. Semi-automated learning and reasoning for PICO methodology, systematic review, and environmental epidemiology.

    Science.gov (United States)

    Robson, Barry

    2016-12-01

    The Q-UEL language of XML-like tags and the associated software applications are providing a valuable toolkit for Evidence Based Medicine (EBM). In this paper the already existing applications, data bases, and tags are brought together with new ones. The particular Q-UEL embodiment used here is the BioIngine. The main challenge is one of bringing together the methods of symbolic reasoning and calculative probabilistic inference that underlie EBM and medical decision making. Some space is taken to review this background. The unification is greatly facilitated by Q-UEL's roots in the notation and algebra of Dirac, and by extending Q-UEL into the Wolfram programming environment. Further, the overall problem of integration is also a relatively simple one because of the nature of Q-UEL as a language for interoperability in healthcare and biomedicine, while the notion of workflow is facilitated because of the EBM best practice known as PICO. What remains difficult is achieving a high degree of overall automation because of a well-known difficulty in capturing human expertise in computers: the Feigenbaum bottleneck.

    2016-06-01

    Volumetry, measurement of extremity volume, is a commonly used method for upper extremity lymphedema (UEL) evaluation. However, comparison between different patients with different physiques is difficult with volumetry, because body-type difference greatly affects arm volume. Seventy arms of 35 participants who had no history of arm edema or breast cancer were evaluated. Arm volume was calculated using a summed truncated cone model, and UEL index was calculated using circumferences and body mass index (BMI). Examinees' BMI was classified into 3 groups, namely, low BMI (BMI, 25 kg/m). Arm volume and UEL index were compared with corresponding BMI groups. Mean (SD) arm volume was 1090.9 (205.5) mL, and UEL index 96.9 (5.6). There were significant differences in arm volume between BMI groups [low BMI vs middle BMI vs high BMI, 945.2 (107.4) vs 1045.2 (87.5) vs 1443.1 (244.4) mL, P 0.5]. Arm volume significantly increased with increase of BMI, whereas UEL index stayed constant regardless of BMI. Upper extremity lymphedema index would allow better body-type corrected arm volume evaluation compared with arm volumetry.

    Serrano Catarinense cheese is a raw bovine milk cheese produced in the region of Santa Catarina, Brazil. Twelve representative strains of Leuconostoc isolated from 20 samples of this artisanal cheese were selected and submitted for evaluation of the acidifying, proteolytic, autolytic, aminopeptidase and lipolytic activities, NaCl and acid resistance, production of dextran and biogenic amines and antimicrobial activity. The aim was to genetically and technologically characterize the Leuconostoc strains in order to use them in mixed starter cultures for cheese manufacture. Leuconostoc mesenteroides subsp. mesenteroides was the species that accounted for the largest proportion of isolates of Leuconostoc genus. Two leuconostoc isolates stood out in the acidifying activity, with reduction in pH of 1.12 and 1.04 units. The isolates showed low proteolytic and autolytic activity. Most of the isolates were dextran producers, presented good resistance to the salt and pH conditions of the cheese and showed antimicrobial activity against cheese pathogen bacteria, and none of them produced biogenic amines. These results allowed the selection of five strains (UEL 04, UEL 12, UEL 18, UEL 21 and UEL 28) as good candidates for use as adjunct cultures for cheese manufacture. © 2018 Society of Chemical Industry. © 2018 Society of Chemical Industry.

    Postoperative ileus (POI) is a frequent complication after abdominal surgery (AS). Until today, neither a prophylaxis nor an evidence-based therapy exists. This originates from the absence of objective parameters evaluating the severity and duration of POI resulting in clinical trials of modest quality. The SmartPill(®), a capsule which frequently measures pH value, temperature and intraluminal pressure after swallowing, offers an elegant option for analysing gastrointestinal (GI) transit times and smooth muscle activity in vivo. As the use in patients in the first months after AS is not covered by the marketing authorisation, we aim to investigate the safety and feasibility of the SmartPill(®) immediately after surgery. Additionally, we analyse the influence of prokinetics and laxatives as well as standardised physiotherapy on postoperative bowel contractility, as scientific evidence of its effects is still lacking. The PIDuSA study is a prospective, single-centre, two-arm, open-label trial. The SmartPill(®) will be applied to 55 patients undergoing AS having a high risk for POI and 10 patients undergoing extra-abdominal surgery rarely developing POI. The primary objective is the safety of the SmartPill(®) in patients after surgery on the basis of adverse device effects/serious adverse device effects (ADE/SADE). The sample size suggests that events with a probability of 3% could be seen with a certainty of 80% for at least once in the sample. Secondary objective is the analysis of postoperative intestinal activity in the GI tract in both groups. Furthermore, clinical signs of bowel motility disorders will be correlated to the data measured by the SmartPill(®) to evaluate its significance as an objective parameter for assessing POI severity. Additionally, effects of prokinetics, laxatives and physiotherapy on postoperative peristaltic activity recorded by the SmartPill(®) will be analysed. The protocol was approved by the federal authority (94

    Full Text Available Em um programa de melhoramento, o conhecimento da grandeza das associações entre caracteres de interesse, é de fundamental importância na obtenção de populações melhoradas. O presente trabalho teve como objetivo determinar as correlações genotípicas, fenotípicas e ambientais entre caracteres quantitativos em milho pipoca. Foram avaliados nove genótipos de milho pipoca dispostos no campo em delineamento em blocos casualizados com oito repetições. Os genótipos UEL ZP, UEL SI e UEL PAP revelaram maiores capacidades de expansão (27,50; 27,15 e 24,40 respectivamente e número de grãos por volume (244,75; 248,50 e 248,75 respectivamente. A capacidade de expansão revelou correlação fenotípica positiva com o tamanho da pipoca e com o número de grãos por volume, e correlação negativa com massa de grãos por planta. Os caracteres massa de grãos por planta e peso total da espiga revelaram correlações fenotípicas e genotípicas positivas entre si, o que possibilita a utilização de um ou outro na seleção, optando-se pelo que melhor convier aos propósitos do programa de melhoramento.Knowledge of the size of the association among traits of interest is of fundamental importance in a breeding program to allow genetic progress.

    Full Text Available Production systems influence crops differently, mainly in terms of yield. However, there are few studies that have evaluated different bushing snap bean genotypes in different systems. Thus, this study aimed to evaluate the production components and yield of bushing snap beans in conventional and organic production systems. The experimental design was a randomized complete block, in a factorial 6 × 2 arrangement, corresponding to six genotypes and two production systems, with three replications. The genotypes Isla Manteiga Baixo®, Isla Macarrão Baixo®, Feltrin Vicenza Amarelo Baixo®, and Feltrin Macarrão Napoli®, UEL 1, and UEL 2 were submitted to the following determinations: days to flowering; plant height; medium number of pods per plant; average pod mass, length, and diameter; and yield of commercial pods. A joint analysis of variance was conducted by applying the F test, with mean comparison performed using the Tukey’s test (p < 0.05. Anthesis of the genotypes Feltrin Vicenza Amarelo Baixo, UEL 2, Isla Macarrão Baixo, and Feltrin Macarrão Napoli is anticipated in the conventional production system. The genotype UEL 2 shows higher precocity in anthesis within the conventional system. The genotypes Isla Manteiga Baixo and UEL 1 produce more pods per plant in the conventional system. In the organic system, the genotype Feltrin Macarrão Napoli produces double the number of pods per plant compared with Isla Manteiga Baixo. The organic system leads to greater plant height and average mass, length, and diameter of pods in relation to the conventional system. The commercial pod yield of bushing snap bean is not altered by differences in the production system or genotype.

    Full Text Available Taking the act of looking as a backbone of this article I analyze the representation of feminine characters in the film Viridiana, directed by Buñuel and the challenge that this approach poses when framing Buñuel's artistic universe. The traditional position of women as silenced, absent and excluded in the patriarchal system is challenged by a series of transgressive feminine acts of looking that take power away from male characters. By using this atypical ways of looking Buñuel re-imagines women and invents a different way of incorporating language and desire into the cinematic text. Viridiana is read here as and atypical text that undermines the practices of dominant culture by ysing an elusive visual language.Tomando como eje estructural el acto de mirar analizo en este trabajo el tratamiento de los personajes femeninos en Viridiana de Buñuel y el desafío que dicho tratamiento plantea a la hora de perfilar el universo buñuelesco. La posición tradicional de la mujer ausente, silenciada y excluida dentro del sistema patriarcal se ve debilitada por una serie de miradas femeninas transgresoras y desestabilizadoras en la medida que usurpan puntualmente el poder masculino. Buñuel, por medio de este atípico acto de mirar, ha conseguido re-imaginar a la mujer, inventar otro modo de incorporar el lenguaje y el deseo femeninos, que si bien no apuntan a rescatar a la mujer de la mirada patriarcal dominante, abren una serie de fisuras en el texto. Viridiana se muestra así como un texto atípico que mina las prácticas de la cultura dominante, a base de un lenguaje cinematográfico extremadamente alusivo.

    To compare the forces resulting from four types of bracket/ligature combinations: ceramic brackets and stainless steel brackets combined with unconventional elastomeric ligatures (UEL) and conventional elastomeric ligatures (CEL) during the leveling and aligning phases of orthodontic therapy. The testing model consisted of five 0.022-inch preadjusted brackets (second premolar, first premolar, canine, lateral incisor, and central incisor) for each of the two bracket types. The canine bracket was welded to a sliding bar that allowed for different amounts of offset in the gingival direction. The forces generated by a 0.014-inch superelastic nickel titanium wire in the presence of either the UEL or CEL bracket/ligature systems at different amounts of upward canine misalignment (1.5 mm, 3 mm, 4.5 mm, and 6 mm) were recorded. Significant differences were found between UEL and CEL systems for all tested variables (P < .01) with the exception of the canine misalignment of 1.5 mm. The average amount of recorded force in the presence of CEL was negligible with 3.0 mm or greater of canine misalignment. On the contrary, during alignment, a force available for tooth movement was recorded in the presence of both ceramic and stainless steel brackets when associated with UEL. The type of ligature used influenced the actual amount of force released by the orthodontic system significantly more than the type of bracket used (stainless steel vs ceramic).

This contamination is due to worldwide fallout by superficial nuclear tests realized from early 1950s to late 1970s by USA, former URSS, UK, France and China. One of theses radioisotopes that have been very studied is cesium-137. Cesium-137 has a half-life of 30.2 years and its biological behavior is similar to the potassium. The behavior in soil matrix, depth distribution, spatial variability and inventories values of cesium-137 has been determinate for several regions of the world. In Brazil, some research groups have worked on this subject, but there are few works published about theses properties of cesium-137. The aim of this paper was study the depth distribution, spatial variability, and inventory of cesium-137 in native forest. Two native forests (Mata 1 and Mata UEL) were sampling in region of Londrina, PR. The results shows that there is a spatial variability of 40% for Mata 1 and 42% for Mata UEL. The depth distribution of cesium-137 for two forests presented a exponential form, characteristic to undisturbed soil. Cesium-137 inventory determinate for Mata 1 was 358 Bq m -2 and for Mata UEL was 320 Bq m -2 . (author)

    Full Text Available The aim of this work was to assess the soil erosion process in native forest by the 137Cs methodology. The mass balance model was applied to assess the rates of soil loss in three native forests around of Londrina city, Paraná, Brazil. 137Cs distribution depth was of exponential type for the three forests and 137Cs inventory was 241 Bq m-2 for Mata 1, 338 Bq m-2 for Mata 2 and 325 Bq m-2 for Mata UEL. The soil loss value calculated for three native forests was: 6,684 kg ha-1 yr-1 for Mata 1, 1,788 kg ha-1 yr-1 for Mata 2 and 4,524 kg ha-1 yr-1 for Mata UEL.O processo de erosão de solo em floresta nativa tem sido pouco investigado. Como a metodologia do césio-137 dá resultados tanto de taxas de erosão de solo como a bioturbação no perfil de solo, ele tem sido usado para avaliar o processo de erosão de solo nestes ecossistemas. O modelo de balanço de massa foi aplicado para avaliar as taxas de perdas de solo em três florestas nativas na região de Londrina, Paraná, Brasil. A distribuição em profundidade do césio-137 para as três florestas é do tipo exponencial. O inventário de césio-137 foi de 241 Bq m-2 para Mata 1, 338 Bq m-2 para Mata 2 e 325 Bq m-2 para Mata UEL.O valor de perda de solo calculado para Mata 1 foi 6,684 kg ha-1 yr-1, 1,788 kg ha-1 yr-1 para Mata 2 e 4,524 kg ha-1 yr-1 para Mata UEL.

    2012-09-01

    Full Text Available Para o desenvolvimento de um programa de melhoramento, a obtenção de informações com base no comportamento "per se" e da capacidade combinatória de um grupo de genitores é uma etapa importante. Especificamente no caso do feijão-de-vagem, hibridações com o feijoeiro comum são usuais, já que ambos pertencem à mesma espécie botânica e muitas vezes características disponíveis no feijão comum não são encontradas no feijão-de-vagem. O objetivo deste trabalho foi avaliar a capacidade combinatória entre quatro genitores de feijão-de-vagem e um de feijão comum, quanto aos caracteres agronômicos. Os genótipos foram escolhidos com base na divergência genética e no comportamento em relação às características morfoagronômicas identificadas em experimentos preliminares. Os cruzamentos foram efetuados considerando-se o esquema de dialelo completo sem os recíprocos. O experimento para avaliar oito caracteres agronômicos de interesse para o feijão-de-vagem foi conduzido em condições de campo, no período de novembro de 2007 a fevereiro de 2008, em blocos casualizados, com quatro repetições, em Tangará da Serra, Mato Grosso. Os genitores 'UEL 1' e 'Novirex,' são os mais indicados para compor programas de melhoramento que visem obter populações promissoras para o desenvolvimento de linhagens superiores. As combinações 'Manteiga Baixo' x 'Novirex' e 'Manteiga Baixo' x 'UEL 1' foram as que mais se destacaram para a maioria das características agronômicas avaliadas com relação aos valores da capacidade específica de combinação, além de terem como genitores 'UEL 1' e 'Novirex' que tiveram as melhores médias e os melhores valores da capacidade geral de combinação.To develop a plant breeding program, information about parentals per se performance and also about genotypes combining ability is an important step.

    2016-03-01

    Full Text Available ABSTRACT The use of plant growth-promoting bacteria is a promising alternative with low environmental impact to increase the efficiency of use of chemical fertilizers, ensuring high yield with better cost-effective ratio. In maize crops, several studies have demonstrated an increased yield when Azospirillum-based inoculants are used. In the case of popcorn, there are no available studies related to use of inoculation and its response on yield parameters. Thus, the aim of this study was to evaluate the field performance of popcorn when inoculated with the commercial product Masterfix L (A. brasilense Ab-V5 and A. brasilense Ab-V6 and the non-commercial inoculant UEL (A. brasilense Ab-V5 + Rhizobium sp. 53GRM1 associated with nitrogen fertilization. The trials were conducted in Londrina and Maringá, Paraná State, Brazil, in a randomized block design with four replications, in a split plot design with the inoculation treatments located in the plots (uninoculated, Masterfix L, and UEL and the different N rates located in the subplots where ammonium sulphate was applied in the topdressing at the V6 stage (0, 50, 100, and 150 kg∙ha–1. The variance analysis showed significant effects (p < 0.05 of inoculation (Londrina environment and N rates (both environments only for grain yield. There was no inoculation effect in the grain yield when inoculants were applied together with N-fertilization at topdressing. In the absence of N-fertilization at topdressing, the inoculants Masterfix L. and UEL promoted higher grain yield as compared to the uninoculated plants, with resulting increases of 13.21 and 26.61% in yield, respectively.

    Fixed orthodontic mechanotherapy is associated with friction between the bracket - wire - ligature interfaces during the sliding mechanics. A sound knowledge of the various factors affecting the magnitude of friction is of paramount importance. The present study was done to analyze and compare the frictional forces generated by a new ceramic (Clarity Advanced) bracket with the conventional, (metal and ceramic) brackets using unconventional and conventional ligation system, and the self-ligating (metal and ceramic) brackets in the dry condition. The various bracket wire ligation combinations were tested in dry condition. The brackets used were of 0.022″ × 0.028″ nominal slot dimension of MBT prescription: Stainless steel (SS) self-ligating bracket (SLB) of (SmartClip), SS Conventional bracket (CB) (Victory series), Ceramic SLB (Clarity SL), Conventional Ceramic bracket with metal slot (Clarity Bracket), Clarity Advanced Ceramic Brackets (Clarity(™) ADVANCED, 3M Unitek). These brackets were used with two types of elastomeric ligatures: Conventional Elastomeric Ligatures (CEL) (Clear medium mini modules) and Unconventional Elastomeric Ligatures (UEL) (Clear medium slide ligatures, Leone orthodontic products). The aligning and the retraction wires were used, i.e., 0.014″ nickel titanium (NiTi) wires and 0.019″ × 0.025″ SS wires, respectively. A universal strength testing machine was used to measure the friction produced between the different bracket, archwires, and ligation combination. This was done with the use of a custom-made jig being in position. Mean, standard deviation, and range were computed for the frictional values obtained. Results were subjected to statistical analysis through ANOVA. The frictional resistance observed in the new Clarity Advanced bracket with a conventional elastomeric ligature was almost similar with the Clarity metal slot bracket with a conventional elastomeric ligature. When using the UEL, the Clarity Advanced bracket

  12. POPPER, a simple programming language for probabilistic semantic inference in medicine.

    Science.gov (United States)

    Robson, Barry

    2015-01-01

    Our previous reports described the use of the Hyperbolic Dirac Net (HDN) as a method for probabilistic inference from medical data, and a proposed probabilistic medical Semantic Web (SW) language Q-UEL to provide that data. Rather like a traditional Bayes Net, that HDN provided estimates of joint and conditional probabilities, and was static, with no need for evolution due to "reasoning". Use of the SW will require, however, (a) at least the semantic triple with more elaborate relations than conditional ones, as seen in use of most verbs and prepositions, and (b) rules for logical, grammatical, and definitional manipulation that can generate changes in the inference net. Here is described the simple POPPER language for medical inference. It can be automatically written by Q-UEL, or by hand. Based on studies with our medical students, it is believed that a tool like this may help in medical education and that a physician unfamiliar with SW science can understand it. It is here used to explore the considerable challenges of assigning probabilities, and not least what the meaning and utility of inference net evolution would be for a physician.

    Hybrid glycopeptide beta-lactam mimetics designed to bind lectins or carbohydrate recognition domains in selectins have been prepared according to a "shape-modulating linker" design. This approach was implemented using the azide-alkyne "click" cycloaddition reaction, and as shown by NMR/MD experiments, binding of the resulting mimetics to Ulex Europaeus Lectin-1 (UEL-1) occurred after a "bent-to-extended" conformational change around a partially rotatable triazolylmethylene moiety.

    Full Text Available The river Tibagi from the city of Londrina, in the years 1970 and 1980 was a subject of much discussion and controversy due to the project of raising its waters to supply the population of the cities of Londrina and region. In articles published in newspapers, especially in the Folha de Londrina, in the 1970s and 1980s, it was identified that, this time, the perception emerged that the river was polluted. Thus, our primary goal in the first part of this research is to investigate how it came to creating this image. Therefore, we used a collection of newspaper clippings about the controversy raised from the waters Tibagi and interviews with Nelson Amanthea civil engineer and agronomist Marcos Antonio Castanheira, both participated in discussions on the project. It was in this period that the ideas of ecology was entered and began to circulate in the city in the late 1970s. In this context, the emergence of the "age of ecology”, allegations and actions to combat pollution started to become more effective and broad, as well as, arose environmental associations, specialized government agencies and specific legislation. Thus, the objective of this research is also investigating the involvement of scientists and institutions in environmental issues through research of river Tibagi that became evident in the late 1980 and early next decade when the University State of Londrina initiated research in Tibagi river basin. Is emphasized the participation of members of the Department of Animal Biology and Plant - UEL, the company Klabin Pulp and Paper, Telêmaco Borba - PR and COPATI - Intermunicipal Consortium of Tibagi Basin, projects and actions in order to promote their recovery. A major action was investigated Project “Appearance of  Fauna and Flora River Tibagi” which became known as “Project Tibagi “.

    Rein Tammiku fotorealistlik pildimaailm on iseseisev organism, mis ajuti genereerib ootamatuid tähenduslikke lühiühendusi. Erinevalt loodusmaalijatest, portreemaalijatest, meremaalijatest ja teistest maalib Rein Tammik pilte. Ta on pildimaalija. Tammikut huvitavad eelkõige visuaalsed paradoksid. Tammik asus juba 1970. aastail ajastuid ühte pilti kokku keevitama. Rembrandti grupiportreele «Kangrute gildi eesistujaist» ilmusid «Visarite» näod, Manet’ «Eine murul» leidis järsku aseme punaruudulisel linal jne. Historitsistlik eklektika - postmodernismi peamisi strateegiaid - on Tammiku loomingus täiesti selgelt loetav, teda on nimetatud esimeseks nõukogude postmodernistiks. Teatav nõukogude ajastu traumaatiline tajumine ilmneb tema töödes suuresti igatsusest kestvuse, jätkuvuse ja üldkehtivuse järele, mida 1970-1980-ndad aastad ei võimaldanud. 1992. aastast resideerub Prantsusmaal

    Tensile properties of the high-deformability dual-phase ferrite-bainite X70 pipeline steel have been investigated at room temperature under the strain rates of 2.5 × 10-5, 1.25 × 10-4, 2.5 × 10-3, and 1.25 × 10-2 s-1. The microstructures at different amount of plastic deformation were examined by using scanning and transmission electron microscopy. Generally, the ductility of typical body-centered cubic steels is reduced when its stain rate increases. However, we observed a different ductility dependence on strain rates in the dual-phase X70 pipeline steel. The uniform elongation (UEL%) and elongation to fracture (EL%) at the strain rate of 2.5 × 10-3 s-1 increase about 54 and 74%, respectively, compared to those at 2.5 × 10-5 s-1. The UEL% and EL% reach to their maximum at the strain rate of 2.5 × 10-3 s-1. This phenomenon was explained by the observed grain structures and dislocation configurations. Whether or not the ductility can be enhanced with increasing strain rates depends on the competition between the homogenization of plastic deformation among the microconstituents (ultra-fine ferrite grains, relatively coarse ferrite grains as well as bainite) and the progress of cracks formed as a consequence of localized inconsistent plastic deformation.

    Full Text Available O teste de progresso (TPMed é uma avaliação cognitiva longitudinal com conteúdo final do curso, que tem por finalidade avaliar a instituição e o desempenho cognitivo dos estudantes. Atualmente, tem sido aplicado em diversas escolas médicas no mundo e no Brasil. A Universidade Estadual de Londrina (UEL implantou esse teste em 1998. Este trabalho apresenta a experiência da UEL na implementação do TPMed como um instrumento de avaliação do curso e alguns resultados desse período: houve aumento na participação dos estudantes para realizar o teste; o desempenho cognitivo dos estudantes apresentou aumento de uma série para outra em cada teste; a média de acertos nas áreas de Clínica Médica foi menor na quinta série, no oitavo e nono TPMed; na Saúde Coletiva, houve alto percentual de acerto nas duas primeiras séries. Tais resultados refletem a estrutura curricular, bem como as potencialidades e fragilidades do curso. O teste de progresso é um bom indicador do processo de auto-avaliação do curso, mas ainda necessita de aprofundamento nos estudos de técnicas de análise dos resultados, para permitir estimar o crescimento cognitivo dos estudantes.

    Full Text Available Calcium ions (Ca play an important role in many biochemical processes, delaying senescence and controlling physiological disorders in fruits and vegetables. The objective of this experiment was to analyze the effect of increasing calcium concentrations in snap beans. Snap bean cultivar UEL 1 was sown in sand containing 80 mg L-1 of calcium supplemented with nutrient solution, plus calcium at different contents: 0, 75, 150 and 300 mg L-1. Ca was mainly recovered in the shoots, followed by roots and pods. Calcium concentrations in the pods were 130, 259, 349 and 515 mg 100 g-1dry matter on a dry weight basis, in relation to the enhancement of calcium contents in the nutrient solution, respectively. A negative relationship between nitrogen content in the pods and calcium concentration in the nutrient solution was observed. Pods from plants grown in a solution without Ca presented necrosis in their apical region. Dieback of roots, shoots and young leaves also occurred under low calcium supply. Dry matter of pods, roots and shoots, number of pods per plant, pod weight and pod length increased proportionally to calcium concentration in solution. Increasing rates of calcium improved biomass production in snap bean cultivar UEL 1.Os íons cálcio apresentam importante papel em muitos processos bioquímicos, retardando a senescência e controlando desordens fisiológicas em frutas e hortaliças.

    The mixing of phosphatidylserine (PS) and phosphatidylcholine (PC) in fluid bilayer model membranes was studied by measuring binding of aqueous Ca2+ ions. The measured [Ca2+]aq was used to derive the activity coefficient for PS, gamma PS, in the lipid mixture. For (16:0, 18:1) PS in binary mixtures with either (16:0, 18:1)PC, (14:1, 14:1)PC, or (18:1, 18:1)PC, gamma PS > 1; i.e., mixing is nonideal, with PS and PC clustered rather than randomly distributed, despite the electrostatic repulsion between PS headgroups. To understand better this mixing behavior, Monte Carlo simulations of the PS/PC distributions were performed, using Kawasaki relaxation. The excess energy was divided into an electrostatic term Uel and one adjustable term including all other nonideal energy contributions, delta Em. Uel was calculated using a discrete charge theory. Kirkwood's coupling parameter method was used to calculate the excess free energy of mixing, delta GEmix, hence In gamma PS,calc. The values of In gamma PS,calc were equalized by adjusting delta Em in order to find the simulated PS/PC distribution that corresponded to the experimental results. We were thus able to compare the smeared charge calculation of [Ca2+]surf with a calculation ("masked evaluation method") that recognized clustering of the negatively charged PS: clustering was found to have a modest effect on [Ca2+]surf, relative to the smeared charge model. Even though both PS and PC tend to cluster, the long-range nature of the electrostatic repulsion reduces the extent of PS clustering at low PS mole fraction compared to PC clustering at an equivalent low PC mole fraction.

  18. The Use of Calixarene Thin Films in the Sensor Array for VOCs Detection and Olfactory Navigation

    2010-02-01

    Full Text Available This work is dedicated to the development of a sensor array for detection of volatile organic chemicals (VOCs in pre-explosive concentrations as well as for olfactory robotic navigation in the frame of two EU projects. A QCM (quartz crystal microbalance sensor array was built utilising quartz crystals spun-coated with thin films of different amphiphilic calixarene molecules to provide a base for pattern recognition of different volatile organic chemicals (VOCs. Commercial Metal-oxide semiconductor (MOS sensors were also used in the same array for the benefit of comparison. The sensor array was tested with a range of organic vapours, such as hydrocarbons, alcohols, ketones, aromatics, etc, in concentrations below LEL and up to UEL (standing for lower and upper explosion limit, respectively; the sensor array proved to be capable of identification and concentration evaluation of a range of VOCs. Comparison of QCM and MOS sensors responses to VOCs in the LEL-UEL range showed the advantage of the former. In addition, the sensor array was tested on the vapours of camphor from cinnamon oil in order to prove the concept of using the "scent marks" for robotic navigation. The results showed that the response signature of QCM coated with calixarenes to camphor is very much different from those of any other VOCs used. Adsorption and de-sorption rates of camphor are also much slower comparing to VOCs due to a high viscosity of the compound. Our experiments demonstrated the suitability of calixarene sensor array for the task and justified the use of camphor as a "scent mark" for olfactory navigation.

The cohesive elements are implemented into ABAQUS/Standard user subroutines(UEL), and the shape of cohesive law is varied by changing parameters in polynomial functions of cohesive traction-separation relations. In particular, crack propagation behaviors are studied by comparing load-displacement curves of the analysis models which have different shapes of cohesive laws with the same values of fracture energy and cohesive strength. Furthermore, the influence of the element size on crack propagation is discussed in this study.

Apesar de sua importância, não é ainda uma prática intensamente presente nos serviços-escola de Psicologia. Com isso, o objetivo deste artigo é discorrer sobre a implementação, a partir de 2015, de um serviço de plantão psicológico no serviço-escola de Psicologia da Universidade Estadual de Londrina (UEL. Tal atividade pôde ser inserida no curso por meio de um projeto de extensão, haja vista a dificuldade existente para tramitação de mudanças curriculares. Fez-se necessária a oferta deste serviço na UEL principalmente com o intuito de acolher a longa fila de espera para psicoterapia individual. Para a realização do plantão psicológico foram selecionados e treinados estudantes de Psicologia de 4° e 5° ano. O treinamento ocorreu via leitura e discussão de textos e pela realização de entrevistas de triagem com pessoas inscritas na lista de espera para a psicoterapia. Posteriormente estes discentes passaram a receber supervisão grupal semanal. Por meio desta experiência observou-se tanto a importância desempenhada pela intervenção para o público atendido quanto à necessidade de maior diálogo entre os serviços que compõem a rede interna e externa de saúde.

    Full Text Available Appendiceal tumors are rare and usually presented as acute appendicitis. They are incidentally discovered at an emergency surgery, in which case the decision-making is very difficult. The purpose of this report is discuss to the most appropriate management for appendiceal tumors. A retrospective analysis of one case treated at HU-UEL was undertaken and the literature was reviewed. The conclusion is that frozen section should be done whenever the appendiceal findings are atypical. For appendiceal carcinoids greater than 2 cm and adenocarcinomas, a right hemicolectomy is recommended. Appendectomy is apropriate for patients whose carcinoid tumors are 1 cm in diameter or less and for carcinoid tumors between 1 cm and 2 cm without extensive lymphatic permeation and mesenteric invasion. Every case should be searched for synchronous tumors.

    2016-01-01

    Full Text Available Based on the finite element software ABAQUS and graded element method, we developed a dummy node fracture element, wrote the user subroutines UMAT and UEL, and solved the energy release rate component of functionally graded material (FGM plates with cracks. An interface element tailored for the virtual crack closure technique (VCCT was applied. Fixed cracks and moving cracks under dynamic loads were simulated. The results were compared to other VCCT-based analyses. With the implementation of a crack speed function within the element, it can be easily expanded to the cases of varying crack velocities, without convergence difficulty for all cases. Neither singular element nor collapsed element was required. Therefore, due to its simplicity, the VCCT interface element is a potential tool for engineers to conduct dynamic fracture analysis in conjunction with commercial finite element analysis codes.

    Further development of ploughs and the available technology enable the application of stripping in deposits, which did not permit efficient plough operation in the past. Power equalisation between the drives is certainly the optimum solution for some of the applications with internal power consumption. However, it has emerged that the simple transition from the passive hydraulic to the active electrical system with use of the same gear is not the best method. Hence the idea of upgrading a plough gear with integrated overload protection to a load equalising gear was conceived. This system is known as S 15 UeL with LA 15 and conforms to the standardization efforts of Ruhrkohle AG. If the advantages of active power equalisation are dispensed with, the PL 15-S (Safesydor) can be used with ideally integrated overload protection. (orig.).

    2009-01-01

    Material defects such as cavities have great effects on the damage process in ductile materials. Computations based on finite element methods (FEMs) often suffer from instability due to material failure as well as large distortions. To improve computational efficiency and robustness the element-free Galerkin (EFG) method is applied in the micro-mechanical constitute damage model proposed by Gurson and modified by Tvergaard and Needleman (the GTN damage model). The EFG algorithm is implemented in the general purpose finite element code ABAQUS via the user interface UEL. With the help of the EFG method, damage processes in uniaxial tension specimens and notched specimens are analyzed and verified with experimental data. Computational results reveal that the damage which takes place in the interior of specimens will extend to the exterior and cause fracture of specimens; the damage is a fast procedure relative to the whole tensing process. The EFG method provides more stable and robust numerical solution in comparing with the FEM analysis

    2013-01-01

    The stress increments depend not only on the plastic strain but also on the gradient of plastic strain, when the characteristic length scale associated with non-uniform plastic deformation is on the order of microns. In the present research, the Taylor-based nonlocal theory of plasticity (TNT plasticity), with considering both geometrically necessary dislocations and statistically stored dislocations, is applied to investigated the effect of particle shapes on the strain gradient and mechanical properties of SiC particle reinforced aluminum composites (SiC/Al composites). Based on this theory, a two-dimensional axial symmetry cell model is built in the ABAQUS finite element code through its USER-ELEMENT (UEL) interface. Some comparisons with the classical plastic theory demonstrate that the effective stress predicted by TNT plasticity is obviously higher than that predicted by classical plastic theory. The results also demonstrate that the irregular particles cause higher effective gradient strain which is attributed to the fact that angular shape particles give more geometrically.

    Cesium-137 is an artificial radionuclide introduced in the environment through the radioactive fallout of the superficial tests of nuclear weapons. The cesium-137 deposition occurred to middles of the 1980-decade and, due to the Chernobyl accident, great part of Europe had a additional fallout of cesium-137. The contaminations of this accident do not have reached Southern Hemisphere. Cesium-137 is an alkaline metal, high electropositive, that in contact with the soil is strongly adsorbed to the clay in the FES (Frayed Edge Sites) and RES (Regular Edge Sites) positions, and it movement by chemical processes in the soil is insignificant. Because of this, cesium-137 became a good soil marker, and its movement is related to the soil movement particles, so that the cesium-137 have been used in the study of the soil redistribution processes, as a tool of quantifying the rates of soil losses and gain. To use this methodology, it is necessary the knowledge of the reference inventory of cesium-137, that is given as function of the total concentration of cesium-137 deposited in an area by the radioactive fallout. If a sampling point presents less cesium-137 than the reference inventory, this point is considered a point with soil loss; otherwise, the point is considered a point with soil deposition. To evaluate the cesium-137 inventory in the Londrina region, four areas of the undisturbed soil were sampling in grid of 3x3, with a distance of 9 meters among the points. Of these four sampling areas, three areas were of native forest (labeled Mata1, Mata2 and Mata UEL), and one was a pasture area. Cesium-137 inventory was 223 ± 41 Bq m -2 , 240 ± 65 Bq m -2 and 305 ± 36 Bq m -2 for Mata UEL, Mata1 and Mata2, respectively, and of 211 ± 28 Bq m -2 for the native pasture. Considering the deviation in each value, it is not possible to conclude that there are differences among the values of cesium-137 inventory, so that the average reference inventory of cesium-137 for the

    In this work a numerical finite element framework is implemented to enable the integration of coupled multiscale and multiphysics transport processes. A User Element subroutine (UEL) in Abaqus is used to simultaneously solve stress equilibrium, heat conduction, and multiple diffusion equations for 2D and 3D linear and quadratic elements. Transport processes in concrete structures and their degradation mechanisms are presented along with the discretization of the governing equations. The multiphysics modeling framework is theoretically extended to the linear elastic fracture mechanics (LEFM) by introducing the eXtended Finite Element Method (XFEM) and based on the XFEM user element implementation of Giner et al. [2009]. A damage model that takes into account the damage contribution from the different degradation mechanisms is theoretically developed. The total contribution of damage is forwarded to a Multi-Stage Fatigue (MSF) model to enable the assessment of the fatigue life and the deterioration of reinforced concrete structures in a nuclear power plant. Finally, two examples are presented to illustrate the developed multiphysics user element implementation and the XFEM implementation of Giner et al. [2009].

To such an extent, the present study aimed to evaluate the nutrition of plants due to electrical conductivity of nutrient using different substrates. The experiment was conducted at the Agrarian Sciences Center at UEL. For the cultivation was used UEL-2 bean pod type, which has determined growth, average height of 40 cm, straight pods with flat section and harvest around 55 days after planting. The experiment outline was randomized blocks with subdivided plots. The plots were composed by treatments holding nutrient solutions with electrical conductivity of: 0.5, 1.0, 1.5 and 2.0 mS cm-1 and subdivisions composed by substrates consisting of: carbonized rice hulls, Pinus bark and a combination of 50% carbonized rice hulls + 50% pine bark. A total of 60 pots of 5 liters each were used, each one holding two plants that were watered twice a day, with the aid of manual watering, containing 150 ml of variable nutrient solution, depending on each of the treatments electrical conductivity. The levels of fresh and dry matter of roots, stems, leaves and pods, pod length and diameter, electrical conductivity and pH’s of eluviated ones were analyzed throughout the whole cycle. The obtained results were submitted to analysis of variance and the substrates averages compared by the Tukey test at 5% probability, and the quantities of electrical conductivity by means of regression. The use of nutrient solution with electrical conductivity of 1.5 mS cm-1 and the substrate containing 50% pine bark over 50% carbonized rice hulls resulted in increased productivity, with 182 g pot-1, corresponding to 1.09kg m2. At the same time, the use of carbonized rice hulls substrate with the electrical conductivity of 0.5 mS cm-1 showed the worst

    For several decades state organizations and engineering societies have published strict engineering guidelines for the design and safe management of storage tanks. Storage tanks in refineries and chemical plants can contain flammable and hazardous chemicals. Accidents in these systems resulting from explosions can cause million dollar property loss and production interruption. In severe cases lawsuits may result and companies can even be driven into bankruptcy. This article focuses on tests which have been conducted by the PROTEGO Research and Development Group in Braunschweig, Germany. Latest research, in which conservation vents have been tested in accordance to the new ISO 16852 test method, have proven that conservation vents cannot be used to substitute a flame arrester if potentially explosive atmospheres are present in storage tanks. This research was conducted during the development of ISO 28300 and the test results are considered in this standard. This paper will prove that the use of conservation vents to protect tanks from atmospheric explosion is not a reliable protection method when the vapor/air mixtures in the tank have a concentration between the Upper and Lower Explosive Limits (UEL and LEL). This is very common for Ethanol storage which is globally in evidence. (author)

  15. Cohesive Zone Model Based Numerical Analysis of Steel-Concrete Composite Structure Push-Out Tests

    2014-01-01

    Full Text Available Push-out tests were widely used to determine the shear bearing capacity and shear stiffness of shear connectors in steel-concrete composite structures. The finite element method was one efficient alternative to push-out testing. This paper focused on a simulation analysis of the interface between concrete slabs and steel girder flanges as well as the interface of the shear connectors and the surrounding concrete. A cohesive zone model was used to simulate the tangential sliding and normal separation of the interfaces. Then, a zero-thickness cohesive element was implemented via the user-defined element subroutine UEL in the software ABAQUS, and a multiple broken line mode was used to define the constitutive relations of the cohesive zone. A three-dimensional numerical analysis model was established for push-out testing to analyze the load-displacement curves of the push-out test process, interface relative displacement, and interface stress distribution. This method was found to accurately calculate the shear capacity and shear stiffness of shear connectors. The numerical results showed that the multiple broken lines mode cohesive zone model could describe the nonlinear mechanical behavior of the interface between steel and concrete and that a discontinuous deformation numerical simulation could be implemented.

    Full Text Available Organizations are subjected to different pressures in order to persist over time, facilitating the emergence of an aggressive type of management that is called Toxic Management, understood as a way of exercising power through egocentric behavior, lacking empathy, ruthlessness and personal ambition. The behavioral characteristics of those who hold this type of management are related to emotional skills, based on emotional intelligence, which is the ability of the individual to recognize and control his own feelings, hold an empathic attitude and manage interpersonal relationships. The objective of this research was to analyze the relationship between emotional intelligence and toxic management among the Heads of the Academic Departments and/or Program Coordinators at the Universidad de Oriente, Sucre Campus, Cumaná. The field research was performed at a descriptive- correlational level. The level of emotional intelligence was measured by the test designed by Goleman, and for the toxic management the test proposed by Piñuel was used. The results show that the level of emotional intelligence of the sample studied is medium-high, while the risk of the job management is moderate. There is a strong positive correlation between the variables studied, indicating that the level of toxicity depends on the ability of the individual to manage emotional competencies

    A new trend in the production technology of solid biof uels has appeared. There is a wide consensus that most solid biofuels will be produced according to the new production methods within a few years. Numerous samples were manufactured from agro-residues according to conventional methods as well as new methods. Robust analyses that reviewed the hygienic, environmental, financial and ethical aspects were performed. The hygienic and environmental aspect was assessed by robust chemical and technical analyses. The financial aspect was assessed by energy cost breakdown. The ethical point of view was built on the above stated findings, the survey questionnaire and critical discussion with the literature. It is concluded that the new production methods are significantly favourable from both the hygienic and environmental points of view. Financial indicators do not allow the expressing of any preference. Regarding the ethical aspect, it is concluded that the new methods are beneficial in terms of environmental responsibility. However, it showed that most of the customers that took part in the survey are price oriented and therefore they tend to prefer the cheaper-conventional alternative. In the long term it can be assumed that expansion of the new technology and competition among manufacturers will reduce the costs.

    This work is aimed at improvement of HTGR neutron physics design calculations by application of uncertainty analysis with the use of cross-section covariance information. Methodology and codes for preparation of multigroup libraries of covariance information for individual isotopes from the basic 44-group library of SCALE-6 code system were developed. A 69-group library of covariance information in a special format for main isotopes and elements typical for high temperature gas cooled reactors (HTGR) was generated. This library can be used for estimation of uncertainties, associated with nuclear data, in analysis of HTGR neutron physics with design codes. As an example, calculations of one-group cross-section uncertainties for fission and capture reactions for main isotopes of the MHTGR-350 benchmark, as well as uncertainties of the multiplication factor (k∞) for the MHTGR-350 fuel compact cell model and fuel block model were performed. These uncertainties were estimated by the developed technology with the use of WIMS-D code and modules of SCALE-6 code system, namely, by TSUNAMI, KENO-VI and SAMS. Eight most important reactions on isotopes for MHTGR-350 benchmark were identified, namely: 10B(capt), 238U(n,γ), ν5, 235U(n,γ), 238U(el), natC(el), 235U(fiss)-235U(n,γ), 235U(fiss).

    LPG (Liquefied Petroleum Gas). LPG is a hydrocarbon gas production from refineries and gas refinery with the major components of propane gas (C3H8) and butane (C4H10). Limit flame (Flammable Range) or also called gas with air. Value Lower Explosive Limit (LEL) is the minimum limit of the concentration of fuel vapor in the air which if there is no source of fire, the gas will be burned. While the value of the Upper Explosive Limit (UEL), which limits the maximum concentration of fuel vapor in the air, which if no source of fire, the gas will be burned. Protection system is a defend mechanism of human, equipment, and buildings around the protected area. Goals to be achieved in this research are to design a protection system against the consequences caused by the leakage of LPG gas based on ATmega16 microcontroller. The method used in this research is to reduce the levels of leaked LPG and turned off the power source when the leakage of LPG is on the verge of explosive limit. The design of this protection system works accurately between 200 ppm up to 10000 ppm, which is still below the threshold of explosive. Thus protecting the early result of that will result in the leakage of LPG gas.

    Gomez-Farias, Armando; Montoya, Arturo; Millwater, Harry

    2015-01-01

    The complex finite element method (ZFEM) has been extended to perform sensitivity analysis for mechanical and structural systems undergoing creep deformation. ZFEM uses a complex finite element formulation to provide shape, material, and loading derivatives of the system response, providing an insight into the essential factors which control the behavior of the system as a function of time. A complex variable-based quadrilateral user element (UEL) subroutine implementing the power law creep constitutive formulation was incorporated within the Abaqus commercial finite element software. The results of the complex finite element computations were verified by comparing them to the reference solution for the steady-state creep problem of a thick-walled cylinder in the power law creep range. A practical application of the ZFEM implementation to creep deformation analysis is the calculation of the skeletal point of a notched bar test from a single ZFEM run. In contrast, the standard finite element procedure requires multiple runs. The value of the skeletal point is that it identifies the location where the stress state is accurate, regardless of the certainty of the creep material properties. - Highlights: • A novel finite element sensitivity method (ZFEM) for creep was introduced. • ZFEM has the capability to calculate accurate partial derivatives. • ZFEM can be used for identification of the skeletal point of creep structures. • ZFEM can be easily implemented in a commercial software, e.g. Abaqus. • ZFEM results were shown to be in excellent agreement with analytical solutions

    2017-11-01

    A comprehensive study on a finite-deformation gradient crystal-plasticity model which has been derived based on Gurtin's framework (Int J Plast 24:702-725, 2008) is carried out here. This systematic investigation on the different roles of governing components of the model represents the strength of this framework in the prediction of a wide range of hardening behaviors as well as rate-dependent and scale-variation responses in a single crystal. The model is represented in the reference configuration for the purpose of numerical implementation and then implemented in the FEM software ABAQUS via a user-defined subroutine (UEL). Furthermore, a function of accumulation rates of dislocations is employed and viewed as a measure of formation of short-range interactions. Our simulation results reveal that the dissipative gradient strengthening can be identified as a source of isotropic-hardening behavior, which may represent the effect of irrecoverable work introduced by Gurtin and Ohno (J Mech Phys Solids 59:320-343, 2011). Here, the variation of size dependency at different magnitude of a rate-sensitivity parameter is also discussed. Moreover, an observation of effect of a distinctive feature in the model which explains the effect of distortion of crystal lattice in the reference configuration is reported in this study for the first time. In addition, plastic flows in predefined slip systems and expansion of accumulation of GNDs are distinctly observed in varying scales and under different loading conditions.

    Full Text Available We study the evolution of the discourse on Spanish TV news referred the topic of Climate Change (CC in the context of the Climate Summits in Cancun (2010 and Durban (2011. The corpus consists of the entire universe of all the records on Spanish television channels whose agenda items relates to this topic. This analysis belongs to the research project I + D Ref CSO2010-16936COMU, entitled " The Hegemonic  Discourse of Media (Risk, Uncertainly and Conflict on "Climate Change”, and experimental testing among young people with other models of alternative discourse", and includes not only the records of informative coverage of both summits, discussed here, but also the records on the subject of climate change appeared in the news for all channels during the time between both summits. The comparison between the production of informative discourses related to climate summit, offers the opportunity to rule on the analysis of its development, whether the development of the economic crisis, which also affects the media, influences the hegemonic discourse that occurs on Climate Change. This analysis used data from the content analysis of television news records, designed in the context of R & D research referred (Teso & Aguila 2011; Piñuel & Teso, 2012. We conclude that the economic crisis affects the conditions of production in that discourse in the source selection more than the choice of subjects in the story.

    Analysis benchmarking was used to assess the accuracy and time efficiency of algorithms suitable for automated delamination growth analysis. First, the Floating Node Method (FNM) was introduced and its combination with a simple exponential growth law (Paris Law) and Virtual Crack Closure technique (VCCT) was discussed. Implementation of the method into a user element (UEL) in Abaqus/Standard(Registered TradeMark) was also presented. For the assessment of growth prediction capabilities, an existing benchmark case based on the Double Cantilever Beam (DCB) specimen was briefly summarized. Additionally, the development of new benchmark cases based on the Mixed-Mode Bending (MMB) specimen to assess the growth prediction capabilities under mixed-mode I/II conditions was discussed in detail. A comparison was presented, in which the benchmark cases were used to assess the existing low-cycle fatigue analysis tool in Abaqus/Standard(Registered TradeMark) in comparison to the FNM-VCCT fatigue growth analysis implementation. The low-cycle fatigue analysis tool in Abaqus/Standard(Registered TradeMark) was able to yield results that were in good agreement with the DCB benchmark example. Results for the MMB benchmark cases, however, only captured the trend correctly. The user element (FNM-VCCT) always yielded results that were in excellent agreement with all benchmark cases, at a fraction of the analysis time. The ability to assess the implementation of two methods in one finite element code illustrated the value of establishing benchmark solutions.

    Full Text Available Neurosurgeries are frequent in the routine of veterinary hospitals and, therefore, knowledge of the different anesthetic protocols to be used for each patient is necessary to prevent the morbity and mortality in the after and trans-surgical period. The objectives of this study were to evaluate the anesthetic protocols used in patients undergoing neurosurgeries; the results of those protocols; the rate of complications, and if those complications are related to the duration of the anesthesia time. We studied the anesthetical data of 52 dogs and two cats submitted to neurosurgery between January of 2003 and December of 2006, in the Veterinary Hospital of UEL. Findings showed that the main protocols used were propofol for induction and halothane or isofluorane for maintenance of the anesthesia. These protocols induced adequate anesthesia for the surgical procedure and did not occur complications during the anesthetic period in 37/54 (68,5% of the cases. 7/19 (36.8% of the complications observed occurred in patients submitted to anesthesia with halothane and 8/32 (25.2% in patients with isofluorane. The complication most observed in this study was bradicardy, which occurred in 15/54 (27.8% of the patients. Two deaths occurred in patients submitted to “slot” cervical. Good knowledge of the neurological disease and of surgical and anesthetic techniques are essential to prevent alterations in the central nervous system caused by the drugs, disease or association of these factors.Neurocirurgias são cada vez mais freqüentes na rotina dos hospitais veterinários, sendo necessário o conhecimento dos diferentes protocolos anestésicos para tais procedimentos, com a finalidade de evitar morbidade e mortalidade no período trans e pós-cirúrgico.

    Full Text Available The low availability of phosphorus is among the factors that limit the development of the Stylosanthes. Only with the appropriate management aiming to increase the phosphorus liberation in the soil we can provide the increase in yield of this leguminous plant. The study was conducted in a greenhouse at the University of Londrina (UEL, the objective was to evaluate the effect of P shoots of Stylosanthes capitata in soil with sandy texture (Typical Yellow Dystropic – LVAd and clay (Typical Eutrophic – Lvef. The experimental design used was completely randomized with four replications in a 2x5x2 factorial design, in which the factors were two soil types, five shots of phosphorus (0, 40, 80, 120 and 160 kg ha-1 of P2O5 and two cuts. For the sowing, seeds of Stylosanthes capitata were used. The aerial part’s cuts were made at 60 and 105 days after sowing. Regardless of the texture and cut, the phosphated fertilization increased the dry matter production of Stylosanthes’ aerial part, and the maximum yield was obtained with a shot of 105 kg ha-1 P2O5. Among the soils the biggest production was obtained in the second cut and soil of sandy texture. With the increase of the doses, the phosphorus content increases in dry matter yield, improving their nutritional quality for animal feed. The maximum dry matter production (2.39 g / plant in sandy soil and 1.36 g / plant in clay soil were obtained with doses of 102.69 and 113.25 kg ha-1 P2O5, respectively.A baixa disponibilidade de fósforo (P está entre os fatores que limitam o desenvolvimento do estilosante.

    Microstructural parameters evaluation of porous materials, such as, rocks reservoir (water, petroleum, gas...), it is of great importance for several knowledge areas. In this context, the X-ray microtomography (μ-CT) has been showing a technical one quite useful for the analysis of such rocks (sandstone, limestone and carbonate), object of great interest of the petroleum and water industries, because it facilitates the characterization of important parameters, among them, porosity, permeability, grains or pore size distribution. The X-ray microtomography is a non-destructive method, that besides already facilitating the reuse of the samples analyzed, it also supplies images 2-D and 3-D of the sample. In this work samples of reservoir rock of the Guarani aquifer will be analyzed, given by the company of perforation of wells artesian Blue Water, in the municipal district of Videira, Santa Catarina, Brazil. The acquisition of the microtomographys data of the reservoir rocks was accomplished in a Skyscan 1172 μ-CT scanner, installed in Applied Nuclear Physics Laboratory (LFNA) in the State University of Londrina (UEL), Paraná, Brazil. In this context, this work presents the microstructural characterization of reservoir rock sample of the Guarani aquifer, analyzed for two space resolutions, 2.8 μm and 4.8 μm, where determined average porosity was 28.5% and 21.9%, respectively. Besides, we also determined the pore size distribution for both resolutions. Two 3-D images were generated of this sample, one for each space resolution, in which it is possible to visualize the internal structure of the same ones.

    Full text: Metal contacts on semiconductors have been an important area for device manufacture. The possibility of lattice matched growth of magnetic metals on semiconductors was once thought to be a unobtainable goal. More recently it has been found that transition metals can react with the semiconductor substrates, forming another lattice with a more comparable lattice constant, from which epitaxial growth can then proceed. Al grows epitaxially on GaN even with a lattice mismatch greater than 10%. In this instance, Al displaces Ga being driven by a larger heat of formation to produce an AlN buffer layer, on which Al can then grow. This paper investigates the room temperature deposition of Mn onto GaAs(100) at room temperature. The Photoemission study was carried out at the UEL56/2 PGM2 beam line at BESSY II in Berlin, Germany. Synchrotron radiation was used to observe the surface as thin layers of Mn were deposited. The interaction of manganese with the substrate tends to donate electron density to neighbouring atoms, decreasing binding energy. No further segregation of substitutional or interstitial Mn and Ga can be seen from angle dependence data at this temperature, with metallic manganese eventually attenuating the bulk Ga signal to the point where it is indistinguishable from the background. It is concluded that there the metal reacts with the semiconductor surface with some indiffusion as confirmed using SIMS. Previously, the reaction was only thought to have taken place above room temperature. The resulting structure consists of a Ga-As-Mn buffer layer as with the higher temperature depositions

    The X-ray fluorescence technique by energy dispersion (EDXRF), being a multi elemental and non-destructive technique, has been widely used in the analysis of artworks and archeometry. An X-ray fluorescence portable equipment from the Laboratory of Applied Nuclear Physics of the State University of Londrina (LFNA/UEL) was used for the measurement of pigments in golden parts of a Gilding Preparation Standard Plaque and also pigments measurement on the Wood Adornment of the High Altar Column of the Side Pulpit of the Immaculate Conception Church Parish Sao Paulo-SP. The portable X-ray fluorescence PXRF-LFNA-02 consists of an X-ray tube with Ag anode, a Si-PIN detector (FWHM=221 eV for Mn line at 5.9 keV), a chain of electronics nuclear standard of X-ray spectrometer, a multichannel 8K, a notebook and a mechanical system designed for the positioning of detector and X-ray tube, which allows movements with two degrees of freedom from the system of excitation-detection. The excitation-detection time of each measurement was 100 and 500 s, respectively. The presence of elements Ti, Cr, Fe, Cu, Zn and Au was found in the golden area of the Altar Column ornament. On the other hand, analysis of the ratios for the intensities of Kα/Kβ lines measured in the areas made it possible to explore the possibility of measuring the stratigraphies of the layers of pigments and to estimate the thickness of the same.

    Airborne measurements of a large number of oxygenated organic chemicals (Oxorgs) were carried out in the Pacific troposphere (0.1-12 km) in the Spring of 2001 (Feb. 24-April 10). Specifically these measuremen ts included acetone, methylethyl ketone (MEK), methanol, ethanol, ace taldehyde, propionaldehyde, PANS, and organic nitrates. Complementary measurements of formaldehyde, organic peroxides, and tracers were al so available. Ox-orgs were abundant in the clean troposphere and were greatly enhanced in the outflow regions from Asia. Their mixing ratios were typically highest in the lower troposphere and declined toward s the upper troposphere and the lowermost stratosphere. Their total a bundance (Ox-orgs) significantly exceeded that of NMHC (C2-C8 NMHC). A comparison of these data with observations collected some seven yea rs earlier (Feb.-March, 1994), did not reveal any significant changes . Throughout the troposphere mixing ratios of Ox-orgs were strongly c orrelated with each other as well as with tracers of fossil and bioma sshiof'uel combustion. Analysis of the relative enhancement of selected Oxorgs with respect to CH3Cl and CO in twelve sampled plumes, origi nating from fires, is used to assess their primary and secondary sour ces from biomass combustion. The composition of these plumes also ind icates a large shift of reactive nitrogen into the PAN reservoir ther eby limiting ozone formation. The Harvard 3-D photochemical model, th at uses state of the art chemistry and source information, is used to compare simulated and observed mixing ratios of selected species. A 1 -D model is used to explore the chemistry of aldehydes. These results will be presented.

    Full Text Available The objective of this study was to evaluate the influence of feeding energy levels during the last third of gestation and lactation on performance of ewes and lambs up to weaning. The experiment was carried out in the sheep raising sector of Universidade Estadual de Londrina (UEL, from August to December of 2007. Thirty-two adult lambs with 105 days of gestation, average live weight of 57.55 kg and average body condition scores of 3.42 were used in the beginning of the experiment. The animals were confined in collective pens, distributed randomly in three treatments: 2.4; 2.2 and 2.0 Mcal of metabolizable energy (ME/kg of dry matter (DM. Feed supply was ad libitum during the last third of gestation and lactation. Weaning occurred at 70 days. Body weight, body condition score and milk production of ewes and body weight of the lambs were analyzed. There were no significant differences for body weight and body condition of ewes at lambing; however, the level of 2.4 Mcal enabled better results for those characteristics at weaning and higher gain in weight and body condition scoring during the experiment. Severe energetic restriction (2.0 Mcal ME/kg DM determined lower average daily milk production. Lambs from levels 2.4 and 2.2 presented similar weights in all measurements and were superior to those in level 2.0. Lambs from level 2.4 presented higher average weight gain from birth to weaning. The energetic restriction upon lambs at the end of gestation and during lactation limits the performance of ewes and lambs up to weaning.

    Rural communities in the Haut-Uele Province of northern Democratic Republic of Congo live in constant danger of attack and/or abduction by units of the Lord's Resistance Army operating in the region. This pilot study sought to develop and evaluate a community-participative psychosocial intervention involving life skills and relaxation training and Mobile Cinema screenings with this war-affected population living under current threat. 159 war-affected children and young people (aged 7-18) from the villages of Kiliwa and Li-May in north-eastern DR Congo took part in this study. In total, 22% of participants had been abduction previously while 73% had a family member abducted. Symptoms of post-traumatic stress reactions, internalising problems, conduct problems and pro-social behaviour were assessed by blinded interviewers at pre- and post-intervention and at 3-month follow-up. Participants were randomised (with an accompanying caregiver) to 8 sessions of a group-based, community-participative, psychosocial intervention (n=79) carried out by supervised local, lay facilitators or a wait-list control group (n=80). Average seminar attendance rates were high: 88% for participants and 84% for caregivers. Drop-out was low: 97% of participants were assessed at post-intervention and 88% at 3 month follow-up. At post-test, participants reported significantly fewer symptoms of post-traumatic stress reactions compared to controls (Cohen's d=0.40). At 3 month follow up, large improvements in internalising symptoms and moderate improvements in pro-social scores were reported, with caregivers noting a moderate to large decline in conduct problems among the young people.

    This paperwork explains the investigation and measurement of the presence of the landfill gases that is methane (CH 4 ) and other gases that include oxygen (O 2 ), carbon dioxide (CO 2 ), sulphur dioxide (SO 2 ), oxides of nitrogen (NO x ), chlorine (Cl 2 ), hydrogen cyanide (HCN) and hydrogen sulphide (H 2 S) that were carried out at the Pulau Burung Sanitary Landfill disposal site, Penang on the month of March and June 2005. The objectives of this study are to investigate the presence of methane which could contribute to the safety aspect on explosion hazard and discuss briefly the viability of methane for power generation. For this purpose, direct gas measurements were taken from 31 gas wells from the first phase of the landfill. Pulau Burung Sanitary Landfill which is located in the state of Penang, Malaysia with the amount of design volume capacity of 0.85 million m3 and received approximately 350 ton of solid waste per day. From the study, it was found that the concentration of CH 4 averagely ranges from 3.66 % vol to 65.96 % vol. Other gases concentrations are; CO 2 (1.46 %vol - 39.66 % vol), O 2 (0.4 %vol - 14.2 %vol), SO 2 (1.8 ppm - 8.6 ppm), NO x (0.14 ppm - 0.46 ppm), Cl 2 (0.1 ppm - 0.58 ppm), HCN (1 ppm - 138.4 ppm) and H 2 S (0.4 ppm - 140 ppm). Methane dilution down to Explosion Limit (EL) levels that is between 5% (Lower Explosion Limit, LEL) and 15% (Upper Explosion Limit, UEL) is always possible and could poses explosion risk at the site. The viability of power generation from methane gas depends on many factors which will be discussed further in this paper. Most of these factors will rely on the nature of the operation by the landfill operator. (Author)

    Full Text Available A la hora de hablar de la renovación en la fotografía española a mediados del siglo XX, hay que tener en cuenta una pauta estética determinante para su consecución y que se deriva de la aplicación de posiciones realistas al arte. Frente al pictorialismo idealizador, el fotorreportaje se erige en crónica descarnada, no evitando una función crítica, de la situación actual, como ejemplifica el trabajo de Eugene Smith sobre el pueblo extremeño de Deleitosa. Entre los objetivos principales que se pretendía desarrollar, destacamos el dar a conocer algunos de los condicionantes históricos, ideológicos y estéticos de la fotografía desarrollada en España a mediados del siglo XX. La metodología de trabajo se ha basado en la consideración de los textos y las imágenes originales del reportaje citado, la bibliografía existente sobre el tema; comprender las reacciones surgidas en la prensa especializada del momento, y la relación con otras obras que también resultaron polémicas por su grado de realismo y de crítica social, por ejemplo, con algunas películas de Luis Buñuel.When we speak about the renovation of Spanish photography in the middle of the 20th century, it is necessary to bear in mind a concrete guideline which stems from idealized pictorialism to the realistic and even critical photographic chronicle. Certainly, it is a widespread phenomenon extended to other artistic manifestations like literature or the cinema. Inside the photographic plot, the photographic article constitutes the principal way to take it to effect. This emaciated chronicle which bears a critical function of the current situation is exemplified perfectly in the work of the North American Eugene Smith about Deleitosa.

    This work presents the total porosity measurements of the aluminum and silicon carbide (SiC) foams samples. For porosity determination the gamma ray transmission and X-ray microtomography with conic beam techniques were used. These methods have more advantage than conventional ones, because they are non destructive and provide more details of the analyzed material porous structure. The aluminum foam samples with 10, 20, 30, 40 and 45 ppi (pores per inch) and SiC ceramic foam samples with 20, 30, 45, 60, 75, 80 and 90 ppi were analysed by gamma transmission. The SiC 60, 75 and 90 ppi samples were also analyzed by X-ray microtomography. For the gamma ray transmission measurements it was used an {sup 241} Am source (59.53 keV), a NaI(Tl) scintillation detector, collimators, a XYZ micrometric table and standard gamma spectrometry electronics connected to a multichannel analyzer, at the LFNA/UEL. For the X-ray microtomographic measurements, the Fein Focus X-ray system of the Nuclear Instrumentation Laboratory of the COPPE, located at the Universidade Federal do Rio de Janeiro, Rio de Janeiro, RJ, was used. This equipment provide us images with micrometric resolution (53.48 {mu}m) using a conic X-ray beam and bidimensional detection. The microtomographic images were pre-processed and analyzed by the Imago software, developed at Porous Media and Materials Thermophysical Properties Laboratory (LMPT) of the Mechanical Engineering Department, located at Universidade Federal de Santa Catarina, Florianopolis, SC. Employing the The Imago software it was calculated the total porosity, pore size distribution and autocorrelation function C(u) of the binarized microtomographic images of the each sample. The microtomographic 3-D image of each sample was compared with 3-D image reconstructed by the Gaussian truncated method. This method generates a periodic 3-D porous structure by using of the autocorrelation function of one 2-D cross sectional image of the sample. (author)

    Hesong, Zhang; Yonglin, Kang

    With the rapid development of oil and gas industry long distance pipelines inevitably pass through regions with complex geological activities. In order to avoid large deformation the pipelines must be designed based on strain criteria. In this paper the alloy system of X80 high deformability pipeline steel was designed which was 0.25%Mo-0.05%C-1.75%Mn. The effect of controlled cooling process on microstructure and mechanical properties of X80 high deformability pipeline steel were systematically investigated. Through the two-stage controlled cooling process the microstructure of the X80 high deformability pipeline steel were ferrite, bainite and M/A island. There were two kinds of ferrite which were polygonal ferrite (PF) and quasi-polygonal ferrite (QF). The bainite was granular bainite ferrite (GF). Along with the decrease of the start cooling temperature, the volume fraction of ferrite and M/A both increased, the yield ratio (Y/T) decreased, the uniform elongation (uEl) increased firstly with the content of ferrite increased but then decreased with the content and size of M/A increased. When the finish cooling temperature decreasing, the size of M/A became finer. As the start cooling temperature was 690 °C and the finish cooling temperature was 450 °C the volume fraction of ferrite was 23%, the size of ferrite grain was 5μm, the size of M/A island was below 1μm and the structure uniformity was the best. The deformation mechanism of X80 high deformability pipeline steel was analyzed. The best way to improve the work hardening rate was reducing the size of M/A islands on the premise of a certain volume fraction. The decreasing path of instantaneous strain hardening index (n*-value) showed three stages in the deformation process. The n*-value kept stable in the second stage, the reason was that the retained austenite transformed into martensite and the phase transition improved the strain hardening ability of the microstructure. This phenomenon was called

    The X-ray fluorescence technique by energy dispersion (EDXRF), being a multi elemental and non-destructive technique, has been widely used in the analysis of artworks and archeometry. An X-ray fluorescence portable equipment from the Laboratory of Applied Nuclear Physics of the State University of Londrina (LFNA/UEL) was used for the measurement of pigments in golden parts of a Gilding Preparation Standard Plaque and also pigments measurement on the Wood Adornment of the High Altar Column of the Side Pulpit of the Immaculate Conception Church Parish Sao Paulo-SP. The portable X-ray fluorescence PXRF-LFNA-02 consists of an X-ray tube with Ag anode, a Si-PIN detector (FWHM=221 eV for Mn line at 5.9 keV), a chain of electronics nuclear standard of X-ray spectrometer, a multichannel 8 K, a notebook and a mechanical system designed for the positioning of detector and X-ray tube, which allows movements with two degrees of freedom from the system of excitation–detection. The excitation–detection time of each measurement was 100 and 500 s, respectively. The presence of elements Ti, Cr, Fe, Cu, Zn and Au was found in the golden area of the Altar Column ornament. On the other hand, analysis of the ratios for the intensities of K α /K β lines measured in the areas made it possible to explore the possibility of measuring the stratigraphies of the layers of pigments and to estimate the thickness of the same. - Highlights: • The X-ray fluorescence technique by energy dispersion (EDXRF) and an X-ray fluorescence portable equipment are used for measurement of pigments. • Analysis of the ratios for the intensities of K α /K β lines measured in the areas made it possible to explore the possibility of measuring the stratigraphies of the layers of pigments and to estimate the thickness of the same. • The result of pigment analysis performed on these objects indicates that they are of the twentieth century

MÉTODOS: Realizou-se um levantamento através de questionário autoaplicável, previamente testado, entre 154 estudantes do primeiro ao quarto ano de Medicina da Universidade Estadual de Londrina entre setembro e novembro de 2011. RESULTADOS: Foi relatado que 70,8% dos estudantes possuíam algum tipo de erro de refração, sendo a miopia o erro mais prevalente, com 72,5% dos estudantes amétropes apresentando-a, associada ou não a outros erros de refração. Os óculos foram o método de correção visual referido como o mais utilizado, por 80% dos pesquisados. Quanto à cirurgia refrativa, 85,7% dos estudantes já haviam ouvido falar a respeito, porém, apenas 42,9% sabiam como o procedimento é realizado, sendo o oftamologista a principal fonte de informação sobre o tema, para 23,5% dos alunos. Apenas 43,2% dos alunos têm interesse na realização da cirurgia, e apenas 3 (1,9% estudantes já foram submetidos ao procedimento. CONCLUSÃO: Apesar da importância da cirurgia refrativa na Oftalmologia verificou-se baixo conhecimento acerca do tema entre os estudantes, o que afeta o interesse dos mesmos em serem submetidos ao procedimento. Observou-se também uma taxa relativamente alta de falsa expectativa quanto ao seu resultado, principalmente entre os estudantes que querem ser submetidos ao procedimento, provavelmente pelas fontes pouco confiáveis alegadas pelos estudantes. Considerando o fato de que se tratam de futuros médicos, fica clara a necessidade de maiores esclarecimentos sobre o tema na graduação.

    Full Text Available This article sets out to analyse the eye motif in Un chien andalou. The eye—cut open in the film with a razor blade—has a symbolic function that is present in Buñuel’s entire filmography, where eyes are a recurrent motif: from the eyes of people who were born blind, a key character in Buñuel’s films, to the allusions to the spectator’s eyes. This article lists the eyes appearing in Buñuel’s films, and using reception theory, seeks to explain the significance of this visual symbol in the filmmaker’s work. The conclusion is that when the eye appears in a film it means that the images of the film come from the artist’s inner sources. Therefore, the eye in Luis Buñuel’s work refers to a reflection by the filmmaker about his own creative process.Este artículo tiene como objeto realizar un análisis del motivo visual del ojo en Un chien andalou. El ojo, que en esta película es rasurado con una cuchilla, tiene una función simbólica que recorre toda la filmografía de su director. Numerosos ojos aparecen en toda su obra, desde los de los ciegos de nacimiento, una figura esencial en su cine, hasta las alusiones al ojo del espectador. En este artículo realizo una lista de las veces que aparece el motivo del ojo en la obra del cineasta aragonés y mediante los presupuestos de la teoría de la recepción interpreto el significado de dicho símbolo visual en la filmografía de su autor. Se concluye que el ojo en la obra de Luis Buñuel alude a la procedencia interior de las imágenes que componen el film, es decir, a una reflexión del mismo autor sobre su proceso creativo.

    A set of Indian Brazilian pottery fragments belonging to Tupi-Guarani tradition has been studied by EDXRF. The pottery fragments were accidentally discovered in the Santa Dalmacia farm in 1990, sited near Cambe city at the north of Parana Brazilian State. The main objective was to characterize the ceramic paste, as well as the superficial layer of the ceramic fragments, in order to get information about the pigment composition of the plastic decoration. The Energy Dispersive X-ray Fluorescence (EDXRF) methodology was employed to obtain the ceramic paste composition, as well as the superficial layer of the ceramic fragments. The measurements were carried out at CENA. The experimental set up consisted of 238 Pu, 55 Fe and 109 Cd radioactive sources, a X-ray tube (at 15 kV, 40 mA, Mo target and Zr filter), a Si(Li) detector (30 mm 2 , with a Be window ) and a multichannel analyzer. For detection of the elements within the ceramic paste, the fragments were irradiated at the center of the lateral section. While several superficial areas with remaining plastic decoration were also chosen and irradiated at the convex and concave sides of each fragment. X-ray spectra were analyzed at UEL using the AXIL program. A program based on the graphic polygonal representation method was developed and used to correlate the representative intensity data of each fragment. A low Ca content, and a systematic presence of relatively high concentrations of Fe can characterize the ceramic pastes. Ti and Zr are also always present at high levels, and Ni, Cu and in some cases Zn at level of traces; Rb, Sr, Ba and Y are also present at low concentration. The black pigment in the pottery plastic decoration is due to the presence of Mn, the red pigment is due to the presence of Fe, while the white pigment is characterized by the presence of Ba. Other qualitative and quantitative results were obtained for each kind of ceramic fragment groups. For the eleven fragments studied, the polygonal

Para tanto, foram estabelecidos diálogos, principalmente, com a atual produção historiográfica delineada no campo da História Social dedicada ao estudo dos egressos da escravidão em meio à conquista da liberdade, bem como com as contribuições de Jörn Rüsen (2001; 2001b acerca do conceito de narrativa consubstanciadas à luz da Teoria da História. A atual produção historiográfica dedicada à população negra no período pós-emancipação foi enfatizada por dialogar com o objetivo da legislação, ou seja, trazer à tona a historicidade da população afrobrasileira. A narrativa histórica, por sua vez, foi entendida como o modo pela qual se manifesta as representações da humanidade no tempo e, além, a forma pela qual os homens interpretam de forma significativa o tempo a fim de se orientar intencionalmente no mundo. A amostragem envolveu 141 produções narrativas de graduandos do último período das licenciaturas em História da FAFIMAN, UEL, UEM e UENP. Coletadas a partir de instrumento de investigação, essas produções passaram pelo crivo da técnica de análise textual qualitativa e/ou análise de conteúdo desenvolvida por Laurence Bardin (1977. Os resultados da investigação apontaram, em suma, para a implementação das instruções da legislação nos espaços de ensino superior público do norte paranaense mediante a introdução de disciplinas específicas que versam sobre as africanidades. Assinalaram que 91% dos futuros professores aprovam a introdução do ensino e aprendizagem das

    Full Text Available As linguagens visuais nas mídias têm suscitado, graças à ampliação constante do uso de novos dispositivos e da melhoria de suportes, especialmente daqueles que exploram o quesito definição - condição técnica indispensável para adequado trabalho com imagens -, apaixonados estudos de pesquisadores que se dedicam ao campo da comunicação, que não mais podem deixar de lado, ao que tudo indica, mídias que laboram com imagens visuais, caso da fotografia, TV, cinema, multimídias. As páginas de Significação têm registrado tal tendência e, esta edição, exceção feita a um único artigo, não foge à regra que vem se impondo. Os trabalhos de Kati Eliana Caetano, "A encenação da violência: um exemplo no filme Cidade de Deus” e o da dupla espanhola Manuel Palácio e Juan Carlos Ibáñez, "Os esquecidos de Luis Buñuel: o exílio republicano do cineasta espanhol e a revitalização do cinema social em Latino América" investigam, a partir de diferentes pontos de vista e diferenciados propósitos, o cinema. Os artigos de Renato Pucci, "A representação do índio brasileiro na interface pós-moderna de cinema e TV", e o de Sandra Nodari, "Ónibus 174: a intertextualidade entre cinema e televisão", detêm-se nas compatibilidades entre cinema e televisão, quer se apresentem no gênero ficcional, caso do primeiro artigo, ou no documentário, caso do segundo. Em seu artigo, "Programação direta da TV: sentido e hábito", Yvana Fechine, por sua vez, preocupa-se com a programação direta da TV, na qual o sentido, ressemantizado, decorre do hábito de se ver TV diariamente.Greice Schneider e José Benjamim Picado, no artigo "Construção de mundos em fotografias de representações: supressão e ambigüidade em Robert Doisneau", examinam o efeito discurso nas imagens do fotógrafo francês que as transformam em "pequenas narrativas".

    Full Text Available Este estudo analisou a distribuição espacial da avifauna do campus da Universidade Estadual de Londrina em diferentes habitats (florestal, agrupamento de árvores, edificações e adjacências, capoeira, aquático e campo aberto. Também foi desenvolvida uma análise comparativa em relação à riqueza e composição de espécies e à estrutura de guildas entre a comunidade de aves que ocorre em um remanescente florestal que existe no campus com as de um remanescente em área rural, dois remanescentes em área urbana e a de uma área contínua de floresta. Os dados foram coletados em transecções fixas entre janeiro de 2001 e dezembro de 2002 em 48 amostragens. Um total de 174 espécies foi registrado, com os habitats florestal e agrupamento de árvores apresentando maior número de espécies, enquanto os habitats aquático e de campo aberto apresentaram o menor número. A riqueza de espécies registrada no remanescente florestal do campus foi semelhante ao registrado na área contínua e na área rural e superior ao registrado nas duas áreas urbanas. O índice de Sørensen apresentou valores semelhantes e relativamente altos entre o campus e as outras quatro áreas. Por outro lado a estrutura de guildas da comunidade de aves florestais do campus foi mais semelhante o de uma das áreas urbanas e da área rural. Tanto no campus como nas áreas urbanas, houve menor número de espécies de grandes frugívoros e escaladores e um aumento na representatividade de aves de borda de floresta em relação a área contínua de floresta e a área rural.This study analyzed the spatial distribution of the Universidade Estadual de Londrina's (UEL avifaunal in several habitats (forest, scattered trees, buildings and surroundings, shrubs, aquatic and grassland. Besides that, a comparative analysis about the richness and composition of species and the guild structure of forest birds was carried out between the bird community witch was recorded in a forest

  4. Measuring the distribution of equity in terms of energy, environmental, and economic costs in the fuel cycles of alternative fuel vehicles with hydrogen pathway scenarios

    Meyer, Patrick E.

    Numerous analyses exist which examine the energy, environmental, and economic tradeoffs between conventional gasoline vehicles and hydrogen fuel cell vehicles powered by hydrogen produced from a variety of sources. These analyses are commonly referred to as "E3" analyses because of their inclusion of Energy, Environmental, and Economic indicators. Recent research as sought a means to incorporate social Equity into E3 analyses, thus producing an "E4" analysis. However, E4 analyses in the realm of energy policy are uncommon, and in the realm of alternative transportation fuels, E4 analyses are extremely rare. This dissertation discusses the creation of a novel E4 simulation tool usable to weigh energy, environmental, economic, and equity trade-offs between conventional gasoline vehicles and alternative fuel vehicles, with specific application to hydrogen fuel cell vehicles. The model, dubbed the F uel Life-cycle Analysis of Solar Hydrogen -- Energy, Environment, Economic & Equity model, or FLASH-E4, is a total fuel-cycle model that combines energy, environmental, and economic analysis methodologies with the addition of an equity analysis component. The model is capable of providing results regarding total fuel-cycle energy consumption, emissions production, energy and environmental cost, and level of social equity within a population in which low-income drivers use CGV technology and high-income drivers use a number of advanced hydrogen FCV technologies. Using theories of equity and social indicators conceptually embodied in the Lorenz Curve and Gini Index, the equity of the distribution of societal energy and environmental costs are measured for a population in which some drivers use CGVs and other drivers use FCVs. It is found, based on baseline input data representative of the United States (US), that the distribution of energy and environmental costs in a population in which some drivers use CGVs and other drivers use natural gas-based hydrogen FCVs can be

    de Paris, fique em evidência, além de demarcar um território extremamente adequado ao trânsito da primeridade defendida por Peirce. Nessa perspectiva, não resulta estranho, mesmo que se crie um paradoxo, que, no espaço urbano tenhamos também uma paisagem sonora que, assumindo propriedades repetitivas, imita, de algum modo, o processo ritualístico que se acaba de mencionar. Pode-se dizer que também o trabalho destas duas pesquisadoras fornece elementos suficientes para estabelecer relações de conexão entre particularidades aparentemente distantes.Os outros textos centram seu interesse em temas mais concretos, Sandra Fischer e Reto Melchior analisam, respectivamente, processos de intertextualidade em Tudo sobre minha mãe e figurações de espelhamento em La nuit Sacrée. Ambos artigos, porém, apresentam pontos de coincidência e, em certa medida; se complementam no tocante à manipulação de pressupostos semióticos. O trabalho de Javier Herrera-Navarro possui, além da consistência de suas interpretações, o mérito histórico de apresentar por primeira vez ao público brasileiro a obra de Granell, surrealista espanhol que nos legou uma produção pictórica muito pessoal e que escreveu o romance El Indio Tupinambá, obra que foi recomendada a Buñuel como digna de ser filmada. E, finalmente, o artigo que Denize Correa Araujo dedica ao estudo das formas híbridas, tipos de manifestações que caracterizam tendências expressivas de nosso tempo.

    grow due to dissolution of the smaller ones, i.e. the same way as in coagulation of crystal grains in the solid state (i.e. collective crystallisation) [19]. The number of the zones at the given ageing temperature does not depend on the alloy composition.In some alloys, Guinier-Preston zones appear immediately after heat treatment or even during the cooling after heat treatment. At the same time, intermediate phases and stable phases appear after the incubation interval. All these facts show that Guinier-Preston zones are different to intermediate and stable phases. This is why Guinier-Preston zones are often called 'pre-precipitations' to differentiate them from real precipitations of intermediate and stable phases with a qualitatively new structure [19].Unlike such a structured approach that treats Guinier-Preston zones as 'pre-precipitations' from a thermodynamic point of view, they can be treated as independent stable phases, intermediate between the matrix solution and the stable phase. Consequently, these zones can be treated as the second phase that is in metastable equilibrium with the matrix solution.Moreover, a Guinier-Preston zone in the dual Cu-Si system with limited solubility of silicon in solid state can have its own line limit of solubility km (Figure 3). Metastable phases with a high content of silicon in the α-Cu matrix crystalline lattice appear below this line.Provided that the Guinier-Preston zone is treated as a phase, at the moment of its origin, the change of the free energy of the alloy is as follows: ΔU = -ΔUtot + ΔUsurf + ΔUel (Utot - total energy of the system, Usurf - surface energy of the crystal, Uel - elastic energy component). Because of the coherence property of the zone and the matrix, the ΔUsurf component can be neglected as its value is very small. Then, at relatively high oversaturation, the energy barrier for the origin of the Guinier-Preston zone should be relatively small, which explains the occurrence of clusters

    Full Text Available Dos horizontes arquivísticos e de seu sentido É significativo observar que a discussão sobre Arquivologia e sobre as práticas profissionais arquivisticas tem avançado muito nos últimos anos no Brasil, e as razões são claramente apontadas pelos organizadores desta edição especial de Encontros Bibli em seu texto editorial. Contendo sete artigos, esta edição temática traz o título Horizontes Arquivísticos.Para dar vida a este número, foi desenvolvido um trabalho de quase dois anos, liderado pelo pesquisador José Maria Jardim e colaboração de Renata Silva Borges. Aqui estão reunidos nove autores e seis avaliadores, todos vinculados a instituições de ensino e de pesquisa ligadas ao Serviço Público Federal, com sede nas cidades de Brasilia, Rio de Janeiro, Niteroi e Florianópolis: UNB, UNIRIO, UFF, UFRJ, UFSC, Arquivo Nacional e FIOCRUZ.Neste momento da história brasileira ─ em que se anunciam políticas governamentais em prol da cidadania, em que se diz da disposição de resgate da verdade sobre os fatos políticos acontecidos na gestão do estado brasileiro dos anos de 1964 a 1989 ─ os arquivos e seus profissionais passam a divisar um relevante protagonismo. Pode-se dizer que, de certa maneira, deu-se um movimento de preparação deste protagonismo e que, simultaneamente, essa preparação alicerçou a percepção de segmentos importantes do setor público para oferecer essa perspectiva para a sociedade nacional.Nesse sentido, tem peso relevante a instalação de novos cursos de bacharelado na área, totalizando, em 2011, o número de 14 universidades que os oferecem: UNIRIO, UFF, UFSM, UFES, UNB, UEL, UFBA ,UNESP/MARÍLIA, UFRGS, UEPB, UFAM, FURG, UFMG, UFSC. Uma nota marcante é que todas essas Instituições de Ensino Superior têm vínculos governamentais, sendo onze federais e três estaduais. Esse movimento não se faz por outro caminho senão o da pesquisa histórica e social. Em áreas como a História, Educa
