    Full Text Available Para descrever o padrão de construção e ocupação dos ninhos de Ectatomma vizottoi, foram escavados oito ninhos durante o período de novembro de 2004 a agosto de 2006, em Dourados-MS. Os orifícios de entrada ou saída dos ninhos desta espécie possuem formato elipsóide, com acesso a um túnel alargado, similar a uma antecâmara, a qual é conectada a câmaras mais profundas do ninho. Os ninhos podem alcançar até 360,0 cm de profundidade, e apresentam de três a dez câmaras. São construídos independentemente de raízes de plantas, e o solo de seus túneis e câmaras é compactado, apresentando compartimentos específicos para depósitos de detritos da colônia. O aumento da densidade de formigas conduz a um aumento do número de câmaras, bem como da profundidade do ninho, mantendo, entretanto, um volume médio para o mesmo, evidenciando um padrão para o tamanho das câmaras dos ninhos.The construction pattern and occupancy of Ectatomma vizottoi was described, during November 2004-August 2006 period, in Dourados, state of Mato Grosso do Sul by excavation of eight nests. The entrance openings, or exit, have an ellipsoid shape and lead to a wide tunnel, similar to a hall, which is connected to other deeper chambers in the nest. The nests reach up to 360 cm deep and contain three to ten chambers. Nests are constructed independently of plants and roots presence, and the soil of the tunnels and chambers are compacted, with specific compartments for colony deposit of detritus. The increase of the ant density led to an increase in nest depth and number of chambers, maintaining an average nest volume, which indicates a standard size for nest chambers.

    We investigated the changes in the behavioral repertoire over the course of life and determined the life expectancy and entropy of workers of the ant Ectatomma vizottoi. Newly emerged ants were individually marked with model airplane paint for observation of behaviors and determination of the age and life expectancy. Ants were divided into two groups: young and old workers. The 36 behaviors observed were divided into eight categories. Workers exhibit a clear division of tasks throughout their lives, with young workers performing more tasks inside the colony and old workers, outside, unlike species that have small colonies. This species also exhibits an intermediate life expectancy compared to workers of other species that are also intermediary in size. This supports the hypothesis of a relationship between size and maximum life expectancy, but it also suggests that other factors may also be acting in concert. Entropy value shows a high mortality rate during the first life intervals.

    Full Text Available Behavioral differentiation and ovarian development of unmated gynes, queens, and workers of Ectatomma vizottoi were investigated in laboratory conditions. Forty-one behavioral acts were identified and quantified for workers, 19 for queens and 24 for unmated gynes, for an overall species repertoire of 42 different behavioral acts. Ovipositing reproductive eggs was an exclusive task of the queen, whereas workers showed 15 caste-specific behaviors. The most important (frequent behaviors for the queens were brood care, immobility, and reproduction, and for workers were immobility, grooming/interaction, brood care, and foraging. Unmated gynes (not winged primarily showed immobility, brood care, grooming/interaction, and foraging. Analysis of ovarian development showed that unmated gynes had little-developed ovarioles, in contrast to queens. Queens and unmated gynes showed a clear behavioral differentiation, in which queens played the role of reproducers and unmated gynes performed activities belonging to the worker repertoire. Despite the presence of several breeding queens in the colony, functional monogyny was the rule.

  4. Foraging strategies of the ant Ectatomma vizottoi (Hymenoptera, Formicidae

    Full Text Available Foraging strategies of the ant Ectatomma vizottoi (Hymenoptera, Formicidae. Foraging activity may be limited by temperature, humidity, radiation, wind, and other abiotic factors, all of which can affect energy costs during foraging. Ectatomma vizottoi's biology has only recently been studied, and no detailed information is available on its foraging patterns or diet in the field. For this reason, and because foraging activity is an important part of the ecological success of social insects, the present study aimed to investigate E. vizottoi's foraging strategies and dietary habits. First, we determined how abiotic factors constrained E. vizottoi's foraging patterns in the field by monitoring the foraging activity of 16 colonies on eight different days across two seasons. Second, we characterized E. vizottoi's diet by monitoring another set of 26 colonies during peak foraging activity. Our results show that E. vizottoi has foraging strategies that are similar to those of congeneric species. In spite of having a low efficiency index, colonies adopted strategies that allowed them to successfully obtain food resources while avoiding adverse conditions. These strategies included preying on other ant species, a foraging tactic that could arise if a wide variety of food items are not available in the environment or if E. vizottoi simply prefers, regardless of resource availability, to prey on other invertebrates and especially on other ant species.

    Full Text Available Eucharitidae are parasitoids that use immature stages of ants for their development. Kapala Cameron is the genus most frequently collected in the Neotropics, but little is known about the biology and behavior of any of the species of this genus. We aimed to evaluate the effect of habitat type on eucharitid parasitism and to contribute to the knowledge of the host-parasite relationship between Kapala sp. and the poneromorph ant Ectatomma ruidum (Roger in Colombia. Twenty E. ruidum colonies were extracted from two different habitat types (woodland and grassland, and larvae and cocoons (pupae were examined in search for parasitoids in different stages of development. Globally, 60% of the colonies were parasitized, with 1.3% of larvae and 4% of pupae parasitized. Planidia (first-instar larvae, pupae, and adults of the parasitoid were observed. All of the pupae and adult parasitoids belonged to Kapala iridicolor Cameron. All the colonies collected in the woodlands were parasitized and contained more parasitized larvae (2% and parasitized cocoons (8% than those collected in grasslands (4/12 parasitized colonies, 0.5% parasitized larvae, 0.8% parasitized cocoons. The relationship observed between habitat type and parasitism prevalence is a novel aspect of the study of eucharitid impact on ant host populations.

  10. Discrimination of the Social Parasite Ectatomma parasiticum by Its Host Sibling Species (E. tuberculatum

    2013-01-01

    Full Text Available Among social parasites, workerless inquilines entirely depend on their host for survival and reproduction. They are usually close phylogenetic relatives of their host, which raises important questions about their evolutionary history and mechanisms of speciation at play. Here we present new findings on Ectatomma parasiticum, the only inquiline ant described in the Ectatomminae subfamily. Field data confirmed its rarity and local distribution in a facultative polygynous population of E. tuberculatum in Mexico. Genetic analyses demonstrated that the parasite is a sibling species of its host, from which it may have diverged recently. Polygyny is suggested to have favored the evolution of social parasite by sympatric speciation. Nevertheless, host workers from this population were able to discriminate parasites from their conspecifics. They treated the parasitic queens either as individuals of interest or as intruders, depending on their colonial origin, probably because of the peculiar chemical profile of the parasites and/or their reproductive status. We suggest that E. parasiticum could have conserved from its host sibling species the queen-specific substances that produce attracting and settling effect on workers, which, in return, would increase the probability to be detected. This hypothesis could explain the imperfect social integration of the parasite into host colonies.

    Full Text Available The Library of the Ducal Palace at Vila Viçosa preserves three large choirbooks of polyphonic repertoire intended for Holy Week, prepared between 1735 and 1736 by a copyist of the Patriarchal Church. These choirbooks contain all the known extant works by Fernando de Almeida (died in 1660. When comparing the music of Fernando de Almeida with that of his near contemporary João Lourenço Rebelo (1610-1661, the different trends in Portuguese early- to mid-seventeenth-century church music become clear, especially if viewed in the light of the acknowledged aesthetic and compositional premises explained in the 1649 Defensa de la mvsica moderna by King João IV. Rebelo’s concertato works incline towards the style of north-Italian composers. The ingenuity of Fernando de Almeida’s style, which is particularly noticeable in his eight-voice Holy Week responsories, lays in the integration of prominent Baroque features within the mould of Iberian Mannerist tradition.La Biblioteca del Palacio Ducal de Vila Viçosa posee tres grandes libros de coro con repertorio polifónico destinado a la Semana Santa, preparados entre 1735 y 1736 por un copista de la Iglesia Patriarcal.

    Full Text Available Neste artigo, nosso objetivo é resgatar e refletir sobre o papel importante desempenhado por Miguel Ozorio de Almeida no domínio da divulgação científica no Brasil. Este aspecto pouco conhecido de suas atividades não tem recebido a atenção merecida nos estudos da história da ciência no país. Ao longo de sua carreira, o fisiologista fez conferências públicas e publicou vários textos de divulgação, muitos dos quais incluídos nos livros Homens e coisas de ciência, Ensaios, críticas e perfis e A vulgarização do saber. Este último talvez seja a primeira obra brasileira a discutir de forma mais sistemática a prática da divulgação científica, com suas vantagens e limitações. Miguel Ozorio escreveu ainda, em 1933, Almas sem abrigo, romance sobre a vida de um matemático no Brasil, e dirigiu com Humberto Mauro, em 1938, o filme educativo Fisiologia geral.The article rediscovers and explores Miguel Ozorio de Almeida's important role in the realm of scientific dissemination in Brazil.

    Full Text Available Epistemological considerations of philosophers and scientists from the late nineteenth century to the mid-twentieth century guided Brazilian physiologist Miguel Ozório de Almeida (1890-1953 in formulating his researches and participating in national and international scientific debates. With his siblings, Álvaro Ozório de Almeida and Branca de Almeida Fialho, he participated in debates on Brazilian educational and scientific system’s reform and in international organizations. The family’s residence in Rio de Janeiro housed a laboratory that became a reference in experimental physiology researches in Brazil. This article aims to present Miguel Ozório de Almeida’s conception of science, constructed mainly within the private laboratory’s sociability, providing new aspects of scientific work production in Brazil in the early twentieth century. I argue that Ozório de Almeida’s stand as an internationalist physiologist in national and international contexts was related to his reading of texts by Ernest Mach, Pierre Duhem, Henri Poincaré and William James.

    Studies of venomous animals have shown that environmental and genetic factors contribute to determining the chemical composition of venom. It is well known that external effects cause differences in the toxicity, concentration, and prey specificity of venom. However, the influence of different factors on the chemical profile of Hymenoptera venom remains little explored. In view of this, the aim of this study was to evaluate intraspecific differences and the influence of diet on the chemical profile of Ectatomma brunneum venom using Fourier transform infrared photoacoustic spectroscopy. For the study of intraspecific variation of the venom, foragers were collected at locations with different environmental conditions, such as urban, intermediate, woodland and monoculture sites. To investigate the influence of diet on the venom, two colonies were sampled in the same area and were maintained in the laboratory under controlled diet conditions and at room temperature. The mid-infrared absorption spectra obtained were interpreted using discriminant function analysis. The results showed significant differences among the chemical profiles of the venoms of individuals from different environments and individuals exposed to a controlled diet in the laboratory, suggesting that venom composition was determined not only by genetic traits inherent to the species, but also by exogenous factors.

    Professor Maria Cecília Puntel de Almeida (1944-2009) built a professional and academic career of which the main feature was her attempt to create and strengthen the interface between Nursing and Public Health in Brazil. From the beginning of her career she recognized this connection and understood the complexity of health problems and peoples' needs when seeking care. Her commitment took the form of both scientific output and also her contributions to the various fields in which she worked. As well as her contribution to the concept of the work process of nursing, she contributed to thinking on health practices and multi-professional training in the construction of a differentiated body of knowledge, which she approached from the perspective of the struggle for democracy in health and understanding of this as a right of citizenship.

    Full Text Available Este artigo empreende um esforço de reintrepretação sobre o desenvolvimentismo no Brasil. Procura repensá-lo a partir da tríade estruturante que lhe confere sentido: um consenso ideológico sobre as potencialidades nacionais, um estilo de reflexão sobre o país e uma aposta no planejamento democrático e descentralizado. A política econômica é encarada mais como ferramenta do que um fim em si mesmo. Para tanto, acompanhou-se a trajetória Rômulo Almeida, de modo a traçar o pano de fundo do Brasil desenvolvimentista entre 1946 e 1964. Um esforço de coleta de material inédito produzido pelo economista baiano ao longo dos anos 1970 permitiu mostrar como ele revê sua rica trajetória de servidor público e oferece uma crítica à política econômica da ditadura militar, partindo de um pensamento sistêmico e de uma dialética planejadora. Ao final, são tecidas algumas considerações acerca das possibilidades de emergência de uma nova perspectiva desenvolvimentista para o país no contexto atual.This paper presents a different approach toward the understanding of developmentalism in Brazil. The intention is to shed light on this process through its three distinct aspects: an ideological consensus on national potential, a methodological apparatus for interpreting the social and economic structures of the country, and a belief on a decentralized and democratic style of State planning. In this regard, economic policy is seen rather as a means than as an end in itself. To accomplish this task, Rômulo Almeida's career within state bureaucracy was studied, which makes it possible to interpret the debate around development in Brazil between 1946 and 1964 from a different perspective. The article is the result of a research effort that revealed new documents produced by the author, especially in the 1970's, in which he not only reconsiders his rich trajectory, but also offers a critical approach toward the economic policies put into place

    2016-09-01

    Full Text Available This study attempts to analyze Pequenos funerais cantantes ao poeta Carlos Maria de Araújo for choir and orchestra written in 1969 by Almeida Prado. This piece became relevant in Prado’s career after winning the I Music Festival of Guanabara. The methodology sought to understand the relationship between the homonymous poem by Hilda Hilst and the its poetic-musical reinvention composed by Almeida Prado by identifying the various compositional procedures employed in all eight parts of the piece. In conclusion, we noticed that the Pequenos funerais cantantes behaves as eight miniatures articulated mainly by differences between the various parts, possibly having, however, a relationship between some, by the use of similar or contrasting compositional procedures. With the analysis in hand, it was possible to achieve a synthesis of the compositional procedures employed in the piece and determine that they had been learned during Almeida Prado’s development as a composer, particularly the period when his main tutors were Camargo Guarnieri (1960-1965 and Gilberto Mendes (1965-1969.

Verifica-se que, se cotejada com balizas culturais contemporâneas, tal configuração de si porta contornos aparentemente paradoxais: ao invés de fortalecer uma identidade pessoal, ela pressupõe uma dinâmica antropológico-religiosa de autoesvaziamento, concomitante a uma atuação mediadora em prol de relações ternárias entre Deus, os sujeitos e si mesmo, processo denominado por D. Luciano como “interiorização da figura Jesus Cristo”. Com o suporte teórico provindo da semiótica e da história religiosa, tal interiorização é aqui compreendida como um programa narrativo específico, que adquiriu formas singulares ao longo dos séculos, com destaque à espiritualidade inaciana, mas preservando sua concepção como um agir, pela fé, em nome da competência atribuída a um Outro. Sugere-se ainda que, na atualidade, a interiorização possa ser aproximada do relato de testemunho, face ao engajamento ético por ela suscitado, que reconfigura o sujeito no compartilhar de experiências vividas e postas em discurso.

    Full Text Available A comissão mista de demarcação da fronteira, determinada pelo Tratado de Santo Ildefonso, seguiu os seus trabalhos de acordo com os critérios definidos pelo Tratado, sendo fundamentais as explorações realizadas pela equipe de engenheiros e astrônomos na Capitania de Mato Grosso, na qual figurava o engenheiro Ricardo Franco de Almeida Serra (1748-1809. Neste artigo é analisado o contexto em que se deu a elaboração do diário de viagem de Ricardo Franco -com as informações sigilosas para a coroa portuguesa sobre o território e com as descrições cartográficas que trouxe- e os objetivos de sua posterior veiculação pela Revista do IHGB, que procurava reforçar a construção de uma ideia de nação para o Brasil independente no período que antecedeu à Guerra da Tríplice Aliança, legitimando através de documentos o domínio do território de sua fronteira oeste, objeto de disputas com Estados vizinhos.

  7. Rowe's Argument from Improvability | Almeida | Philosophical Papers

    African Journals Online (AJOL)

    William Rowe has argued that if there is an infinite sequence of improving worlds then an essentially perfectly good being must actualize some world in the sequence and must not actualize any world in the sequence. Since that is impossible, there exist no perfectly good beings. I show that Rowe's argument assumes that ...

    Full Text Available Considerado "guru dos estilos" e idealizador do conceito "supermercado de estilos", o antropólogo Ted Polhemus é reticente quanto aos "roubos fashion" pela hegemônica indústria da moda e acredita na força e no poder da comunicação visual de estilos e comportamentos como formas de expressão humana. Na conturbada e agitada década de 1960, o antropólogo anglo-americano Ted Polhemus, 57, trocou os EUA pela Inglaterra, em especial, a ensolarada Califórnia (para onde os jovens costumavam ir pela acinzentada e enevoada Londres. Esse contexto político-histórico de busca pela liberdade ideológica da era hippie e expansão da moda com o surgimento do prêt-à-porter possibilitou ao pesquisador estudar antropologia na Temple University, na Filadélfia. Em seguida, em Londres, desenvolveu seus estudos de mestrado sobre "Body Image and Adornment" (Imagem e Adorno do Corpo na prestigiada University of London. O projeto de mapear as inter-relações entre corpo e estilo na concepção de moda e comportamento sempre norteou sua verve intelectual de um antropólogo comprometido com os fenômenos da atualidade, sobretudo os que decorrem a partir da contemporaneidade do século 20. Publicou Fashion & Anti-fashion: anthropology of clothing and adornment (Thames & Hudson, 1979, Streetstyle: from sidewalk to catwalk (Thames & Hudson, 1994 e Style Surfing: what to wear in the 3rd millennium (Thames & Hudson, 1996, entre outros. Em seu novo livro, Hot Bodies, Cool Styles: new techniques in self adornment (Thames & Hudson, 2004, lançado no final do ano passado, o "guru dos estilos" e pai do conceito "supermercado de estilos" dá mostras de como a onda global do entusiasmo para a decoração do corpo é enraizada em nosso passado e examina ainda seu sentido na prospecção do futuro. Polhemus tornou-se referência na literatura de moda e do corpo. Ao lado de outros pesquisadores do assunto, como Dick Hebdige, que conceituou a existência e relações das subculturas nas sociedades, Polhemus é um autêntico exemplo de vitalidade e atualidade ao refletir antropologicamente sobre moda e comportamento das tribos. Polhemus "descobriu" o Brasil: "É preciso mostrar ao mundo que o Brasil se encontra hoje muito bem servido quanto a criatividade e excelência em moda" e alerta que "nenhum estilista, nem mesmo grife alguma, tomada individualmente, pode fazer esse trabalho sozinho". A seguir, leia entrevista de Polhemus, que esteve em agosto de 2004 pela primeira vez no Brasil, para o workshop "Brand Brasil: como os brasileiros imaginam que os estrangeiros imaginam o país", além da palestra "Ideas Brands: a aparência como marca individual", na Faculdade Senac de Moda, em São Paulo.

  9. Pentastomid, Raillietiella mottae Almeida, Freire and Lopes, 2008, infecting lizards in an area of caatinga, northeast, Brazil

    Full Text Available Pentastomids can infect the respiratory tract of lizards, causing their death and as a result influencing the population size of hosts. Despite this, studies on rates of pulmonary infection of Brazilian lizards, including those living in Caatinga ecosystems of northeastern Brazil are scarce. Active collections of lizards were performed from October to December 2004 in an area of Caatinga of the Estação Experimental de São João do Cariri - EESJC (07º 25' S and 36º 30' W, located in the state of Paraíba, Northeast of Brazil. Forty-five lizards inhabiting granite outcrops in an area of Caatinga were captured, belonging to the following species: Tropidurus hispidus (Spix, 1825 (18 individuals, T. semitaeniatus (Spix, 1825 (15 individuals, Phyllopezus periosus Rodrigues, 1986 (6 individuals, and P. pollicaris (Spix, 1825 (6 individuals. Laboratory examination revealed that all species had some degree of pulmonary infection caused by Raillietiella mottae. The highest rates of prevalence (66.7% and mean intensity of infection (5.25 ± 2.01, range of 2-11 were observed in P. periosus. The results obtained in this study show that lizards of the Brazilian semi-arid region are infected by a generalist species of pentastomid. The most likely cause for such pattern is the similarity in lizards' diets (ants and termites. It is particularly noteworthy that T. semitaeniatus, P. periosus, and P. pollicaris represent new host records for R. mottae.

    Full Text Available Seeking to investigate the ant fauna in degraded environments and to comprehend how this group behaves in such ecosystems, faunistic analysis was initially conducted with the ants collected in an area in Chapecó town that had been subjected to flooding in function of the construction of the mouth of a dam on the Chapecó River (a branch of the larger Uruguay River. The collections were carried out between October 2001 and September 2002. We used pit-fall traps, sweeping nets, entomologic umbrellas and leaf litter collections for fragments covered by bushes and grass. The fauna was characterized through the constancy and dominancy indexes. A number of 34.642 specimens of ants, belonging to 32 species, 19 genera and six subfamilies, were collected. The species Labidus sp., Atta sp. and Ectatomma edentatum stood out as being either accessory or both constant and dominant.

    Full Text Available As formigas, quando atraídas por um apêndice nutritivo, produzido na semente de certas plantas, podem exercer o papel de agente predador ou dispersor das sementes. No processo de dispersão, grande número desses insetos pode interagir com sementes de determinada planta. O objetivo deste trabalho foi identificar as espécies de formigas em contato com sementes de Mabea fistulifera Mart. - uma espécie arbórea e colonizadora em áreas antrópicas no Brasil - e o tipo de interação desses insetos com as sementes, bem como determinar as espécies dispersoras. Foram realizadas coletas manuais de formigas em fragmentos de vegetação com alta densidade de M. fistulifera, no município de Viçosa, MG, no momento de sua visitação às sementes. As formigas capturadas foram triadas e identificadas por espécie. Além disso, durante as coletas foram feitas observações quanto ao tipo de comportamento das formigas que se associaram às sementes e ao cálculo da taxa de remoção destas, verificando-se que 16 espécies tiveram contato com estas. Acromyrmex subterraneus subterraneus, Atta sexdens rubropilosa, Ectatomma edentatum, Pachycondyla sp.1 e Pheidole sp. 2 foram, de fato, dispersoras, já que transportaram efetivamente as sementes. Ac. subterraneus subterraneus, Camponotus rufipes, Ectatomma permagnum, Megalomyrmex sp.1, Pachycondyla sp. 1, Pachycondyla sp. 2, Pheidole sp. 4, Pheidole sp. 5 e Pogonomyrmex sp. são, pela primeira vez, relatadas interagindo com sementes. A taxa de remoção das sementes de M. fistulifera pelas formigas foi de 85 a 97%.Ants, when attracted by nutritious corpuscles produced by seeds of certain plant species, can act as predators or dispersing agents. During seed dispersal, a great number of ant species can interact with seeds of a particular plant species.

  15. Non-integrability of the Anisotropic Stormer Problem and the Isosceles Three-Body Problem

    2009-02-01

    We study the Anisotropic Stormer Problem (ASP) and the Isosceles Three-Body Problem (IP), from the viewpoint of integrability, using Morales-Ramis theory and its generalization. The study of their integrability presents particular interest since they model important physical phenomena. Both problems can be reduced with respect to the S1 symmetry. Almeida and Stuchi [M.A. Almeida, T.J. Stuchi, Non-integrability of the anisotropic Stormer problem with angular momentum, Physica D 189 (2004) 219-233] proved that the reduced ASP is non-integrable for almost all values of the parameters. In this paper we establish the non-integrability (in the extended Liouville sense) of the remaining cases. The IP is a special case of the three-body problem and it can be considered as a generalization of the Sitnikov problem. Here we prove that the complexified reduced IP does not admit an additional independent meromorphic first integral.

  8. Poneromorph Ants Associated with Parasitoid Wasps of the Genus Kapala Cameron (Hymenoptera: Eucharitidae in French Guiana

    Directory of Open Access Journals (Sweden)

    Jean-Paul Lachaud

    2012-01-01

    Full Text Available Eucharitid wasps are specific, specialized parasitoids of ants. The genus Kapala Cameron is the most common in the Neotropics but few species are described, and information dealing with their biology, behavior and host associations is scarce. Numerous poneromorph ant colonies were inspected over 4 collection surveys in French Guiana. A diverse fauna of parasites and parasitoids was found, including mermithid nematodes, flies, eucharitids, and another gregarious endoparasitoid wasp. Five new host associations for Kapala are reported, all of them involving medium- to large-size poneromorph ant species from 4 genera: Ectatomma brunneum Fr. Smith, Gnamptogenys tortuolosa (Fr. Smith, Odontomachus haematodus (L., O. mayi Mann, and Pachycondyla verenae (Forel. Three other associations involving O. hastatus (Fabr., P. apicalis (Latreille, and P. stigma (Fabr., already reported for other countries but new for French Guiana, are confirmed. The data extend the number of hosts for Kapala to 24 ant species from 7 genera. The high diversity of the ant host genera associated with Kapala, combined with the fact that these ant genera are the most widely distributed among Neotropical poneromorph ants, could account for the dominant status of the genus Kapala among the eucharitine wasps of Central and South America.

  10. Variable Alkaloid Defenses in the Dendrobatid Poison Frog Oophaga pumilio are Perceived as Differences in Palatability to Arthropods.

    Conspicuously colored dendrobatid frogs sequester alkaloid defenses from dietary arthropods, resulting in considerable alkaloid variation among populations; however, little is known about how variation is perceived as a defense against predators. Previous studies have found variable alkaloids in the dendrobatid Oophaga pumilio to be associated with differences in toxicity to laboratory mice, suggesting variable defenses are important. Arthropods are natural predators that use chemoreception to detect prey, including frogs, and may therefore perceive variation in alkaloid profiles as differences in palatability. The goal of the present study is to determine how arthropods respond to variable alkaloid defenses in O. pumilio. Frog alkaloids were sampled from individual O. pumilio from ten geographic locations throughout the Bocas del Toro region of Panama and the Caribbean coast of Costa Rica. Alkaloid extracts were used in feeding bioassays with the vinegar fly Drosophila melanogaster and the ant Ectatomma ruidum. Both species of arthropods fed significantly less on frog alkaloid extracts when compared to controls, and differences in alkaloid palatability were observed among frog populations, as well as between sexes and life stages within a population. Differences in alkaloid quantity, richness, and type were the main predictors of arthropod palatability. Our findings also represent the first direct evidence of a palatability spectrum in a vertebrate that sequesters chemical defenses from dietary sources. Further, the presence of a palatability spectrum suggests that variable alkaloid defenses in O. pumilio are ecologically relevant and play an important role in natural predator-prey interactions, particularly with respect to arthropod predators.

  11. Cleptobiosis in Social Insects

    Michael D. Breed

    2012-01-01

    Full Text Available In this review of cleptobiosis, we not only focus on social insects, but also consider broader issues and concepts relating to the theft of food among animals. Cleptobiosis occurs when members of a species steal food, or sometimes nesting materials or other items of value, either from members of the same or a different species. This simple definition is not universally used, and there is some terminological confusion among cleptobiosis, cleptoparasitism, brood parasitism, and inquilinism. We first discuss the definitions of these terms and the confusion that arises from varying usage of the words. We consider that cleptobiosis usually is derived evolutionarily from established foraging behaviors. Cleptobionts can succeed by deception or by force, and we review the literature on cleptobiosis by deception or force in social insects. We focus on the best known examples of cleptobiosis, the ectatommine ant Ectatomma ruidum, the harvester ant Messor capitatus, and the stingless bee Lestrimellita limão. Cleptobiosis is facilitated either by deception or physical force, and we discuss both mechanisms. Part of this discussion is an analysis of the ecological implications (competition by interference and the evolutionary effects of cleptobiosis. We conclude with a comment on how cleptobiosis can increase the risk of disease or parasite spread among colonies of social insects.

    The metapleural gland is exclusive to ants, and unusual among exocrine glands in having no mechanism for closure and retention of secretion. As yet, no clear conclusion has been reached as to the function of metapleural gland secretion. Metapleural gland secretions were investigated for fungus-growing ants representing the derived attines Trachymyrmex fuscus, Atta laevigata, and Acromyrmex coronatus, the basal attines Apterostigma pilosum and Mycetarotes parallelus, and non-fungus-growing ants of the tribes Ectatommini (Ectatomma brunneum) and Myrmicini (Pogonomyrmex naegeli). Our results showed that the secretions of leaf-cutting ants (A. laevigata and A. coronatus) and the derived attine, T. fuscus, contain a greater variety and larger quantities of volatile compounds than those of myrmicine and ectatommine ants. The most abundant compounds found in the metapleural glands of A. laevigata and A. coronatus were hydroxyacids, and phenylacetic acid (only in A. laevigata). Indole was present in all groups examined, while skatole was found in large quantities only in attines. Ketones and aldehydes are present in the secretion of some attines. Esters are present in the metapleural gland secretion of all species examined, although mainly in A. laevigata, A. coronatus, and T. fuscus. Compared with basal attines and non-fungus-growing ants, the metapleural glands of leaf-cutting ants produce more acidic compounds that may have an antibiotic or antifungal function.

    Full Text Available Recentemente, o emprego do termo paradigma chegou ao âmbito epidemiológico. Este texto analisou criticamente uma classificação de 'paradigmas epidemiológicos', proposta por Almeida-Filho. Inicialmente constatou-se que os valores não foram considerados como elementos fundamentais para a construção dos paradigmas, distanciando-se, assim, da matriz kuhniana. Uma vez que a sistematização procurou unir tendências antitéticas, ela pareceu estar mais próxima da epistéme foucaultiana. Finalmente, considerou-se mais apropriada a utilização do termo hegemonia, em vez de paradigma, para sistematizar períodos epidemiológicos, pois os valores das vertentes estão comprometidos com a particularidade (principalmente classe social.Use of the term paradigm has recently reached the epidemiological milieu. This article provides a critical analysis of a classification of "epidemiological paradigms" as proposed by Almeida-Filho. It was initially ascertained that values were not considered fundamental elements for the construction of paradigms, and that they therefore distanced themselves from the Kuhnian matrix. Systematization sought to unite antithetical tendencies and thus seemed closer to the Foucaltian epistéme. Finally, hegemony was considered a more appropriate term than paradigm for systematizing epidemiological periods, since the values of the different watersheds are committed to particularity (principally social class.

  12. Astronomy in Brazilian music and poetry

    2011-06-01

    The rôle of astronomy in the Brazilian cultural diversity -though little known world- has been enormous. Thus, the different forms of popular music and erudite, find musical compositions and lyrics inspired by the stars, the eclipses in rare phenomena such as the transit of Venus in front of the sun in 1882, the appearance of Halley's Comet in 1910, in the Big Bang theory. Even in the carnival parades of the blocks at the beginning of the century astronomy was present. More recently, the parade of 1997, the samba school Unidos do Viradouro, under the direction of Joãozinho Trinta, offered a new picture of the first moments of the creation of the universe to join in the white and dark in the components of their school, the idea of matter and anti-matter that reigned in the early moments of the creation of the universe in an explosion of joy. Examples in classical music include Dawn of Carlos Gomes and Carta Celeste by Almeida Prado. Unlike The Planets by Gustav Holst -who between 1914 and 1916 composed a symphonical tribute to the solar system based on astrology- Almeida Prado composed a symphony that is not limited to the world of planets, penetrating the deep cosmos of galaxies.

Contudo, dados sobre morfologia e distribuição das estruturas secretoras presentes em Mansoa são escassos e ausentes para M. standleyi. O presente trabalho objetivou caracterizar a ocorrência e morfologia das estruturas secretoras do eixo vegetativo aéreo de M. standleyi. Para tanto, amostras da lâmina foliolar e de regiões nodais foram fixadas e submetidas às técnicas histológicas e de microscopia eletrônica de varredura. Testes histoquímicos, com os respectivos controles foram aplicados nas estruturas secretoras em fase secretora. Indivíduos de formigas e moscas, que visitavam a espécie foram amostrados, preservados e identificados por entomólogo. As estruturas secretoras do eixo vegetativo aéreo de M. standleyi estão representadas por tricomas glandulares dos tipos pateliformes e peltados. Todos com desenvolvimento assincrônico e presentes nas regiões nodais e lâmina foliolar, principalmente nas partes mais jovens. Nas regiões nodais, os tricomas formam um complexo secretor e, na lâmina foliolar, estão dispersos. As análises histoquímicas revelaram que os tricomas pateliformes são de fato nectários extraflorais e que os tricomas peltados, apresentam uma fração de alcaloides.

  18. Indirect effects of mutualism: ant-treehopper associations deter pollinators and reduce reproduction in a tropical shrub.

    Science.gov (United States)

    Ibarra-Isassi, Javier; Oliveira, Paulo S

    2018-03-01

    Animal-pollinated plants can be susceptible to changes in pollinator availability. Honeydew-producing treehoppers frequently occur on inflorescences, potentially enhancing ant-mediated negative effects on pollination services. However, the effect of ant-attended, honeydew-producing insects on plant reproduction remains uncertain. We recorded the abundance of treehoppers and ants on Byrsonima intermedia (Malpighiaceae), and monitored floral visitors in a Brazilian cerrado savanna. We manipulated the presence of ants and ant-treehopper associations on inflorescences to assess their effect on pollination and fruit formation. We used dried ants pinned to inflorescences to evaluate the effect of ant presence and ant identity on potential pollinators. Results show that the presence of treehoppers increases ant abundance on flowers and disrupts pollination by oil-collecting bees, decreasing the frequency and duration of floral visits and reducing fruit and seed set. Treehopper herbivory has no direct effect on fruit or seed production, which are independent of treehopper density. Pinned ants promote avoidance by floral visitors, reducing the number of visits. Ant identity mediates visitation decisions, with Ectatomma brunneum causing greater avoidance by floral visitors than Camponotus rufipes. Field videos show that pollinating bees are harassed by ants near flowers, prompting avoidance behavior by the bees. This is the first demonstration of indirect effects by honeydew-gathering ants, via disrupted pollination, on plant reproduction in tropical cerrado savanna. Our results highlight the importance of studying other interactions near flowers, in addition to just observing pollinators, for a proper understanding of plant reproduction.

  19. Pericarpial nectary-visiting ants do not provide fruit protection against pre-dispersal seed predators regardless of ant species composition and resource availability.

    Directory of Open Access Journals (Sweden)

    Priscila Andre Sanz-Veiga

    Full Text Available Extrafloral nectaries can occur in both vegetative and reproductive plant structures. In many Rubiaceae species in the Brazilian Cerrado, after corolla abscission, the floral nectary continues to secret nectar throughout fruit development originating post-floral pericarpial nectaries which commonly attract many ant species. The occurrence of such nectar secreting structures might be strategic for fruit protection against seed predators, as plants are expected to invest higher on more valuable and vulnerable parts. Here, we performed ant exclusion experiments to investigate whether the interaction with ants mediated by the pericarpial nectaries of Tocoyena formosa affects plant reproductive success by reducing the number of pre-dispersal seed predators. We also assessed whether ant protection was dependent on ant species composition and resource availability. Although most of the plants were visited by large and aggressive ant species, such as Ectatomma tuberculatum and species of the genus Camponotus, ants did not protect fruits against seed predators. Furthermore, the result of the interaction was neither related to ant species composition nor to the availability of resources. We suggest that these results may be related to the nature and behavior of the most important seed predators, like Hemicolpus abdominalis weevil which the exoskeleton toughness prevent it from being predated by most ant species. On the other hand, not explored factors, such as reward quality, local ant abundance, ant colony characteristics and/or the presence of alternative energetic sources could also account for variations in ant frequency, composition, and finally ant protective effects, highlighting the conditionality of facultative plant-ant mutualisms.

For example, when the index for the development of Portuguese as a Foreign Language in Brazil is considered, the topic of official policies deserves one of the lowest scores among the fourteen criteria taken into consideration in the paper by Almeida Filho (2007. Why does this happen? Is the prospect similar for the languages most commonly taught at schools? What is a language teaching policy in the realm of a supposed language policy enforced in the country? Which are the contours of a policy needed for official purposes and by the institutions?

OBJETIVOS: Clarificar os conceitos subjacentes ao desenvolvimento do WHOQOL-SRPB. MÉTODO: As questões levantadas por Moreira-Almeida e Koenig (2006 foram discutidas baseados nos objetivos e marco conceitual do WHOQOL-SRPB, bem como, a literatura pertinente. RESULTADOS: 1 o WHOQOL-SRPB não é um instrumento desenvolvido com o objetivo de avaliar o construto SRPB, mas sim qualidade de vida; 2 crenças pessoais podem funcionar como uma estratégia para se conseguir lidar com os problemas, pois dão significado ao comportamento humano e, hipoteticamente, influenciam a QV; 3 SRPB é um construto coerente e pode ser considerado um construto independente de bem-estar psicológico, 4 os conceitos incluídos no projeto WHOQOL foram considerados genuinamente transculturais por consenso e isso é um de seus pontos fortes mais relevantes.

The course takers were selected from two Public Brazilian Universities: The State University of Pará and The Federal University of Pará, by a process which involved previous needs assessment, course design, material selection and continuous collaborative teaching. Contextualized communicative strategies were used in order to facilitate interaction in the foreign languages with distinct groups of foreigners invited for the international event. The theoretical foundation of this paper lies principally on the works of Almeida Filho (1998, Dudley-Evans and St. John (1998, Hutchinson and Waters (1987, Munby (1978 and Nunan (1988. This teaching experience is reported through a qualitative perspective and its positive results were accredited to the effective learning environment created for the development of multicultural linguistic knowledge.

    2015-01-01

    The concept of "scientific culture" varies historically, and the examination of its continuities and transformations can help us understand the relationship between the scientific community and society. The views on the role of science in society go far beyond the advancement of a particular form of knowledge and its possible or promising fruit. They involve values, postures and practices to be disseminated and reveal expectations of social and cultural advancement. This article discusses four expressive visions of different moments in Brazilian history. The formulations of four influential authors in scientific and educational policies of the country at different times are presented and analyzed: Miguel Ozorio de Almeida, Anísio Teixeira, Maurício Rocha e Silva and Carlos Vogt.

  11. Gardner Transition in Physical Dimensions

    The Gardner transition is the transition that at mean-field level separates a stable glass phase from a marginally stable phase. This transition has similarities with the de Almeida-Thouless transition of spin glasses. We have studied a well-understood problem, that of disks moving in a narrow channel, which shows many features usually associated with the Gardner transition. We show that some of these features are artifacts that arise when a disk escapes its local cage during the quench to higher densities. There is evidence that the Gardner transition becomes an avoided transition, in that the correlation length becomes quite large, of order 15 particle diameters, even in our quasi-one-dimensional system.

    Full Text Available Introduction: This is systematization of theoretical and methodological contributions related to the concepts of mediation information and pedagogical mediation in the literature. Objective: To understand possible intersection of information science and Online Education with regard to these concepts to check that both can be considered as analogous in its essence and practice. Methodology: Literature review based on literature by consulting the scientific productions selected in search of SciELO.ORG databases and EBSCO Host, the portal of CAPES / MEC and Google Scholar. Results: The most cited concepts in information science and education were de Almeida Junior (2009 and Masetto (2013, respectively. Conclusion: It is observed that the concept of mediation can move interchangeably between both areas. This is because the evidence found in the productions of the last five years indicate that the concept of information of mediation seems to have found its bases in education (educational psychology.

    Full Text Available Michael Almeida once told me that he thought we were just a couple of hours of conversation away from reaching deep agreement about some important topics in the philosophy of religion pertaining to God, multiverses, and modality. This paper represents my attempt to move this conversation forward and to seek this common ground. Specifically, I respond to Almeida’s paper entitled “The Multiverse and Divine Creation”. In the first four sections, I record my disagreement with him concerning some smaller matters. In Section 5, I try to persuade him that what he considers a ‘bug’ in the theistic multiverse is actually a feature—and a desirable one at that. In Section 6, I close by identifying some points at which our views seem to converge.

We found no parasite pulmonary infection in T. semitaeniatus. However, two pulmonary parasite species were found in the T. hispidus hosts, the pentastomid Raillietiella mottae Almeida, Freire and Lopes, 2008 and the nematode Rhabdias sp. Overall prevalence was 5%. Prevalence of R. mottae was 2.5% and corresponded to only one parasite on each infected host. Prevalence of Rhabdias sp. was 2.5% and the range of infection was 1-2 parasites per host. This represents the first record of Rhabdias infecting lizards of the family Tropiduridae in the Neotropical region. Furthermore, we present a comparison of parameters of infection by pulmonary parasites including some recent studies in Brazil.

Based on Agamben (2005 and Spivak (2010, we try to verify how this infant voice perceives and represents the Angolan context of postcoloniality in both fictional and nonfictional texts by Luanda. For this reason, we have selected Ondjaki’s works which were published in the first decade of the 21st century, namely the moment when the author was firmed as an intellectual and fiction writer.

The study comprised 510 higher education students enrolled in blended online courses offered through Moodle platform during one semester. It considered students from different private and public Portuguese polytechnic schools and universities. Moreira & Almeida (2011 have suggested that CoI framework is a valid, reliable, and efficient measure of its dimensions within the Portuguese population. Although similarities in aspects of social presence were discovered among polytechnic and universities students, the two groups showed some differences. In particular, it was observed that the polytechnic students appear to be a more robust community when compared to university students.

    Full Text Available INTRODUCTION: An epidemiological study was undertaken to identify determinant factors in the occurrence of American cutaneous leishmaniasis in areas under the influence of hydroelectric plants in Paranapanema river, State of Paraná, Brazil. The ecological aspects of the phlebotomine fauna were investigated. METHODS: Sandflies were sampled with automatic light traps from February 2004 to June 2006 at 25 sites in the urban and rural areas of Itambaracá, and in Porto Almeida and São Joaquim do Pontal. RESULTS: A total of 3,187 sandflies of 15 species were captured. Nyssomyia neivai predominated (34.4%, followed by Pintomyia pessoai (32.6%, Migonemyia migonei (11.6%, Nyssomyia whitmani (8.8%, and Pintomyia fischeri (2.7%, all implicated in the transmission of Leishmania. Males predominated for Ny. neivai, and females for the other vector species, with significant statistical differences (p < 0.001. Nyssomyia neivai, Pi. pessoai, Ny. whitmani, Brumptomyia brumpti, Mg. migonei, and Pi. fischeri presented the highest values for the Standardized Species Abundance Index (SSAI. The highest frequencies and diversities were found in the preserved forest in Porto Almeida, followed by forests with degradation in São Joaquim do Pontal and Vila Rural. CONCLUSIONS: Sandflies were captured in all localities, with the five vectors predominating. Ny. neivai had its highest frequencies in nearby peridomestic environments and Pi. pessoai in areas of preserved forests. The highest SSAI values of Ny. neivai and Pi. pessoai reflect their wider dispersion and higher frequencies compared with other species, which seems to indicate that these two species may be transmitting leishmaniasis in the area.

    Full Text Available Francisco de la Torre's Works, published by Quevedo in 1631, enclose a second part, described in later years as an «appendix», with translations that did not belong in the original project prepared by the author some decades before. The summary of the 1588 license for printing describes the work's content as «lyric and adonic verse, and bucolic», without mentioning the translations. The new date throws into question the participation of Almeida and Brocense in the preparation and transmission of the manuscript that came to Quevedo. Therefore, the volume of 1631 cannot be considered as an example of salmantin group's collective poetical essay. Related chronological considerations also throw new light on the relationship between the author and Fernando de Herrera.Las Obras de Francisco de la Torre, publicadas por Quevedo en 1631, incluyen una segunda parte, que más tarde se llamaría «apéndice», con traducciones ajenas al proyecto inicial preparado por el propio autor décadas antes. El sumario de la licencia de impresión de 1588 describe el contenido de la obra aprobada como «los versos líricos y adónicos y la bucólica», sin mencionar las traducciones. La nueva fecha lleva a cuestionar el protagonismo de Almeida y el Brócense en la preparación y transmisión del manuscrito que más tarde llegaría a Quevedo. El volumen de 1631, por lo tanto, no puede considerarse como un exponente de un ejercicio poético colectivo del círculo salmantino. Los datos cronológicos también permiten replantear la relación del autor con Fernando de Herrera.

    In this paper, we report the results of a cometary research, developed during the last 10 years by us, involving a criterious analysis of gas and dust production rates in comets directly associated to recent space missions. For the determination of the water release rates we use the framework of the semi-empirical model of observed visual magnitudes [Newburn Jr., R.L. A semi-empirical photometric theory of cometary gas and dust production. Application to P/Halley's production rates, ESA-SP 174, 3, 1981; de Almeida, A.A., Singh, P.D., Huebner, W.F.

In turn, the dust release rates were obtained using the photometric model for dust particles [Newburn Jr., R.L., Spinrad, H. Spectrophotometry of seventeen comets.

    In this article, we introduce ESCOLEX, the first European Portuguese children's lexical database with grade-level-adjusted word frequency statistics. Computed from a 3.2-million-word corpus, ESCOLEX provides 48,381 word forms extracted from 171 elementary and middle school textbooks for 6- to 11-year-old children attending the first six grades in the Portuguese educational system. Like other children's grade-level databases (e.g., Carroll, Davies, & Richman, 1971; Corral, Ferrero, & Goikoetxea, Behavior Research Methods, 41, 1009-1017, 2009; Lété, Sprenger-Charolles, & Colé, Behavior Research Methods, Instruments, & Computers, 36, 156-166, 2004; Zeno, Ivens, Millard, Duvvuri, 1995), ESCOLEX provides four frequency indices for each grade: overall word frequency (F), index of dispersion across the selected textbooks (D), estimated frequency per million words (U), and standard frequency index (SFI). It also provides a new measure, contextual diversity (CD). In addition, the number of letters in the word and its part(s) of speech, number of syllables, syllable structure, and adult frequencies taken from P-PAL (a European Portuguese corpus-based lexical database; Soares, Comesaña, Iriarte, Almeida, Simões, Costa, …, Machado, 2010; Soares, Iriarte, Almeida, Simões, Costa, França, …, Comesaña, in press) are provided. ESCOLEX will be a useful tool both for researchers interested in language processing and development and for professionals in need of verbal materials adjusted to children's developmental stages.

    Full Text Available Abstract:The author of this article defends that the dramatic character of the three Calderonian wife-murderers (don Gutierre Alfonso de Solís, don Lope de Almeida and don Juan Roca doesn´t fit to the noble decorum they should have. First the study presents the virtues ideally associated with the nobility in the Golden Age. Afterwards, the detailed analysis of the behaviour of those husbands reveals some failures in their supposed design as perfect heroes: they don´t dominate their violent passions, they judge precipitately the available data and make some mistakes in the application of the honour code. In consequence, they are imperfect nobles who help in a decisive way —but unnoticed for them— to the tragedies they take the chief role in. Resumen:En este trabajo se defiende que el carácter dramático de los tres uxoricidas calderonianos (don Gutierre Alfonso de Solís, don Lope de Almeida y don Juan Roca no se ajusta en diversas ocasiones al decoro nobiliario que cabría esperar en ellos. Primeramente se establece la nómina de virtudes que se asociaba con la nobleza de manera ideal en la época áurea. Posteriormente, el análisis detallado de la conducta de esos maridos revela fallos en su supuesto diseño como héroes intachables: no dominan sus violentas pasiones, juzgan precipitadamente los datos disponibles y cometen errores en la aplicación del código del honor. Se trata, por tanto, de nobles imperfectos que contribuyen de manera decisiva -aunque inadvertida para ellos- a las tragedias que protagonizan.

    Full Text Available Abstract Background Despite the economic and ecological importance of ants, genomic tools for this family (Formicidae remain woefully scarce. Knowledge of genome size, for example, is a useful and necessary prerequisite for the development of many genomic resources, yet it has been reported for only one ant species (Solenopsis invicta, and the two published estimates for this species differ by 146.7 Mb (0.15 pg. Results Here, we report the genome size for 40 species of ants distributed across 10 of the 20 currently recognized subfamilies, thus making Formicidae the 4th most surveyed insect family and elevating the Hymenoptera to the 5th most surveyed insect order. Our analysis spans much of the ant phylogeny, from the less derived Amblyoponinae and Ponerinae to the more derived Myrmicinae, Formicinae and Dolichoderinae. We include a number of interesting and important taxa, including the invasive Argentine ant (Linepithema humile, Neotropical army ants (genera Eciton and Labidus, trapjaw ants (Odontomachus, fungus-growing ants (Apterostigma, Atta and Sericomyrmex, harvester ants (Messor, Pheidole and Pogonomyrmex, carpenter ants (Camponotus, a fire ant (Solenopsis, and a bulldog ant (Myrmecia. Our results show that ants possess small genomes relative to most other insects, yet genome size varies three-fold across this insect family. Moreover, our data suggest that two whole-genome duplications may have occurred in the ancestors of the modern Ectatomma and Apterostigma. Although some previous studies of other taxa have revealed a relationship between genome size and body size, our phylogenetically-controlled analysis of this correlation did not reveal a significant relationship. Conclusion This is the first analysis of genome size in ants (Formicidae and the first across multiple species of social insects. We show that genome size is a variable trait that can evolve gradually over long time spans, as well as rapidly, through processes that may

    The domestication of plants, animals and microbes by humans are the longest artificial evolution experiments ever performed. The study of these long-term experiments can teach us about the genomics of adaptation through the identification of the genetic bases underlying the traits favoured by humans. In laboratory evolution, the characterization of the molecular changes that evolved specifically in some lineages is straightforward because the ancestors are readily available, for instance in the freezer. However, in the case of domesticated species, the ancestor is often missing, which leads to the necessity of going back to nature in order to infer the most likely ancestral state. Significant and relatively recent examples of this approach include wolves as the closest wild relative to domestic dogs (Axelsson et al. 2013) and teosinte as the closest relative to maize (reviewed in Hake & Ross-Ibarra 2015). In both cases, the joint analysis of domesticated lineages and their wild cousins has been key in reconstructing the molecular history of their domestication. While the identification of closest wild relatives has been done for many plants and animals, these comparisons represent challenges for micro-organisms. This has been the case for the budding yeast Saccharomyces cerevisiae, whose natural ecological niche is particularly challenging to define. For centuries, this unicellular fungus has been the cellular factory for wine, beer and bread crafting, and currently for bioethanol and drug production. While the recent development of genomics has lead to the identification of many genetic elements associated with important wine characteristics, the historical origin of some of the domesticated wine strains has remained elusive due to the lack of knowledge of their close wild relatives. In this issue of Molecular Ecology, Almeida et al. (2015) identified what is to date the closest known wild population of the wine yeast. This population is found associated with

    Full Text Available The expulsion of the Jesuits in all Portuguese domains began in 1755 with the gradual banishment of the religious who lived missions located in the Amazonian state of Great Para and Maranhao, culminating with the general law of expulsion signed on 3 September of 1759 by Joseph I. A decree done on an expedited basis in each of the territories where lived members of Society of Jesus and from which they launched towards papal lands. However, not all the Jesuits were exiled to Italy, a considerable number of them –among we can find all those who were not born in Portugal–, remained captives and confined in convents or cottages qualified as prisons and in military places as the castle of St. George, the strengths of Junqueira, Almeida, Pedrouços, San Julian or the public prison of Belem. That is what this article is about..La expulsión de los jesuitas de todos los dominios portugueses se inició en 1755 con el paulatino destierro de los religiosos que habitaban las misiones situadas en el Estado amazónico de Gran Pará y Maranhao culminando con la ley general de expulsión que firmó José I el 3 de septiembre de 1759. Un decreto que se iría ejecutando de forma expeditiva en cada uno de los territorios lusos donde vivían miembros de la Compañía de Jesús y desde donde iniciaron su diáspora hacia tierras pontificias. Sin embargo, no todos los jesuitas fueron desterrados a Italia, un considerable número de ellos –entre los que encontramos a todos los que no habían nacido en Portugal–, permanecieron cautivos y confinados en conventos o en casas de campo habilitadas como cárceles y en presidios como el castillo de San Jorge, los fuertes de la Junqueira, Almeida, Pedrouços, San Julián o la cárcel pública de Belem.

    2003-01-01

    The Neoproterozoic evolution of the Borborema Province in the east-northeast part of the South American platform exhibits remarkable, much studied granitic plutonism. In 1967 F. F. Almeida and co-workers discriminated a series of granitic typologies as 'Conceicao type', 'Itaporanga type' etc, mostly based upon general geological features and petrographic grounds. This preliminary classification has somehow been maintained in all subsequent papers up to now, despite all the newly observed plutons and the newly generated tectonic, geochemical and isotopic data since then. Samples of these classical types of granites from their type-localities were analyzed geo chronologically using the U-Pb method in zircons in response to the felt needs of the geological community, because previous age-determinations involved less accurate methods. The new data have been added to all other preexisting U-Pb data (from other granitic bodies) obtained over the last decade, making it possible to recognize three main stages of granitic magmatism for the Borborema Province: 650-625 Ma, 580-570 Ma and 545-520 Ma. The last group of dates is closely association with the escape tectonics of the Brasiliano-Pan African collage, which preceded the assembly of the super continental landmass of Western Gondwana.

  4. Spin glasses and algorithm benchmarks: A one-dimensional view

    International Nuclear Information System (INIS)

    Katzgraber, H G

    2008-01-01

    Spin glasses are paradigmatic models that deliver concepts relevant for a variety of systems. However, rigorous analytical results are difficult to obtain for spin-glass models, in particular for realistic short-range models. Therefore large-scale numerical simulations are the tool of choice. Concepts and algorithms derived from the study of spin glasses have been applied to diverse fields in computer science and physics. In this work a one-dimensional long-range spin-glass model with power-law interactions is discussed. The model has the advantage over conventional systems in that by tuning the power-law exponent of the interactions the effective space dimension can be changed thus effectively allowing the study of large high-dimensional spin-glass systems to address questions as diverse as the existence of an Almeida-Thouless line, ultrametricity and chaos in short range spin glasses. Furthermore, because the range of interactions can be changed, the model is a formidable test-bed for optimization algorithms

  5. Identification and Classification of Stakeholders in a Brazilian Professional Soccer Club

    2015-11-01

    Full Text Available Whereas an initial step in the management of stakeholders is the identification and classification of these actors, this study sought to answer the research question: how managers of Brazilian professional soccer clubs identify and classify their stakeholders? The theoretical framework used was the Stakeholder Theory, developed by Freeman (1984 and other researchers. The method used was proposed by Almeida et al. (2000, which assesses the saliency through the concepts power, legitimacy and urgency, that were proposed in the study of Mitchell et al. (1997. There were two propositions concerning the context of Brazilian soccer clubs: first, that the urgency perceived by managers in the demands of a stakeholder is high when his legitimacy is high and other one is that the most salient stakeholders for the managers are those with high degrees of legitimacy. Stakeholders were surveyed as perceived by the managers of Sociedade Esportiva Palmeiras. Three types of stakeholders were classified as demanding (sponsors, partners and the partner for the construction of the new stadium and three as dependents (members, athletes of professional soccer team and the media. Other stakeholders identified were classified as irrelevant, including the fans and and the organized groups of fans. It can be said that in the specific case of these managers of this particular football club, the trend was the acceptance of both propositions.

  7. Approximate message passing for nonconvex sparse regularization with stability and asymptotic analysis

    Sakata, Ayaka; Xu, Yingying

    2018-03-01

    We analyse a linear regression problem with nonconvex regularization called smoothly clipped absolute deviation (SCAD) under an overcomplete Gaussian basis for Gaussian random data. We propose an approximate message passing (AMP) algorithm considering nonconvex regularization, namely SCAD-AMP, and analytically show that the stability condition corresponds to the de Almeida-Thouless condition in spin glass literature. Through asymptotic analysis, we show the correspondence between the density evolution of SCAD-AMP and the replica symmetric (RS) solution. Numerical experiments confirm that for a sufficiently large system size, SCAD-AMP achieves the optimal performance predicted by the replica method. Through replica analysis, a phase transition between replica symmetric and replica symmetry breaking (RSB) region is found in the parameter space of SCAD. The appearance of the RS region for a nonconvex penalty is a significant advantage that indicates the region of smooth landscape of the optimization problem. Furthermore, we analytically show that the statistical representation performance of the SCAD penalty is better than that of \

    The glassy transition of superparamagnetic (SPM) (r glass-like (SGL) behavior near the Curie point (T C ), i.e., T 0 = 330 K, in La 0.67 Sr 0.33 MnO 3 (LSMO) nanofibers (NFs) composed of nanoparticles beyond the SPM size (r ≫ r 0 ), resulting in a significant increase of the glass transition temperature. This SGL transition near the T C of bulk LSMO can be explained to be the scenario of locally ordered clusters embedded in a disordered host, in which the assembly of nanoparticles has a magnetic core-shell model driven by surface spin glass. The presence of a surface spin glass of nanoparticles was proved by the Almeida-Thouless line δT f ∝ H 2/3 , exchange bias, and reduced saturation magnetization of the NF system. Composite dynamics were found - that is, both the SPM and the super-spin-glass (SSG) behavior are found in such an NF system. The bifurcation of the zero-field-cooled (ZFC) and field-cooled (FC) magnetization vs. temperature curves at the ZFC peak, and the flatness of FC magnetization involve SSG, while the frequency-dependent ac susceptibility anomaly follows the Vogel-Fulcher law that implies weak dipole interactions of the SPM model. This finding can help us to find a way to search for high temperature spin glass materials.

    The World Federation of Hemophilia (WFH) 2010 World Congress held in Buenos Aires, Argentina, in July 2010, attracted more than 4,300 participants from 106 countries. This report summarizes two symposia held during the congress. The first, titled "Emerging Co-Morbidities in the Aging Hemophilia Population: Healthcare Challenges and Treatment Opportunities," chaired by Gerry Dolan, MD, and Jussara Almeida Cruz, MD, examined the co-morbidities experienced by the aging hemophilic patient population, such as cardiovascular disease, cancer, arthritis, osteoporosis, hypertension, and obesity. In addition, Bayer's products in preclinical and clinical development were reviewed, including a novel factor VIIa variant and a long-acting factor VIII molecule, i.e., one that has undergone site-specific PEGylation (attachment of polyethylene glycol [PEG] polymer chains to another molecule). The other symposium, titled "Practical Steps to Making Better Care for Hemophilia Patients a Reality," chaired by Carmen Altisent, MD, and Cesar Guerrero, RN, reviewed the steps that hemophilia caregivers can take to improve the care of their patients. Issues such as the treatment of hemarthroses, the role of the research nurse, and the management of pediatric patients transitioning to adulthood were discussed.

    The palette of some of the most representative Brazilian painters from the XIX century was characterized using EDXRF technique. In this work were analyzed paintings of: Eliseu Visconti, Almeida Junior, Rodolfo Amoedo, Henrique Bernardelli, Rafael Frederico, Modesto Brocos, Augusto Rodrigues Duarte and Pedro Peres - all of them belonging to the National Museum of Fine Arts Collection. EDXRF measurements were carried out with a portable system developed by the Nuclear Instrumentation Laboratory, consisting of an X-ray tube Oxford TF3005 with tungsten (W) anode, operating at 25 kV and 100 μA, and a Si-PIN XR-100CR detector from Amptek. In each color and distinct hue of the paint layer were obtained several spectra, with an acquisition time of 300 s and a beam collimation of 2 mm. The spectra were processed and analyzed using the software QXAS-AXIL from IAEA. Some pigments used by the artists were: zinc white, lead white, ochre, umbra, vermilion, Prussian blue, cobalt blue, cadmium yellow, black iron oxide, manganese violet, etc. These results - together with the Computed Radiography analyses - have been used to create a database about the XIX century collection of the National Museum of Fine Arts, in order to assist restorators, conservators, art students and researchers in the field of archaeometry

    Treacher Collins syndrome (TCS, OMIM 154500) is a well-defined mandibulofacial dysostosis characterized by symmetric facial anomalies consisting of malar hypoplasia, coloboma of the lower eyelid, dysplastic ears, micrognathia, cleft palate and deafness. Other mandibulofacial dysostoses (MDs) such as Toriello (OMIM 301950), Bauru (OMIM 604830), Hedera-Toriello-Petty (OMIM 608257), and Guion-Almeida (OMIM 610536) syndromes are less well characterized and much rarer. Here we describe three unrelated patients showing clinical features overlapping with TCS, but who in addition have developmental delay, microcephaly and a distinct facial gestalt. Because of the distinct ear anomalies and the hearing loss a HOXA2 mutation was taken into account. CHARGE syndrome was discussed because of ear anomalies, choanal atresia, and developmental delay in our patients. But mutational analyses including sequencing of the TCOF1, the HOXA2, and the CHD7 genes, deletion screening of the TCOF1 gene as well as genomewide array analyses revealed normal results. We suggest that these three patients have a new type of mandibulofacial dysostosis. As all three cases are sporadic and both sexes are affected the pattern of inheritance might be autosomal dominant or autosomal recessive. Identification of additional patients will allow to further delineate the phenotype, to assign the inheritance pattern and to identify the molecular basis.

    Intravenous access procedures in children are considered to be one of the most stressful because it is invasive, and the use of needles generates anxiety, insecurity, and fear. Playful strategies using dolls and even the materials used for venipuncture can assist children in understanding, accepting, and coping with the procedure. Field research was developed on the applicability of the therapeutic toy in the preparation of preschool children for venipuncture procedure based on the protocol developed by Martins, Ribeiro, Borba, and Silva (2001) and Kiche and Almeida (2009). The study was done in a private hospital in Greater São Paulo, Brazil, with 10 children ages 3 to 6 years. Data were gathered through observation and questionnaires completed by the children's adult guardians. Before the activity, the children showed fearful facial expressions, used monosyllabic responses, and avoided looking at the health care professional. After the strategy of using therapeutic toy dolls and puppets, 40% of the children calmly accepted the venipuncture procedure, and 100% showed a change to their initial negative reaction, became more communicative and cooperative, and participated and interacted with researchers, even after the end of the activity and procedure. The strategy of therapeutic toys helps make an unfamiliar environment, strangers, and a procedure characterized as painful and difficult less stressful. Pediatric nurses are in a good position to use this resource to offer more humanized care to children.

    THE FIRST EUROPEANS to discover Japan were Portuguese traders who arrived in 1542. Fifteen years later, the Portuguese Jesuit priest and surgeon Luis De Almeida (1525-1583) founded the first Western hospital in Japan, for the care of lepers, syphilitics, and orphans. Because the hospital had a negative influence on the spread of Christianity, the Jesuits closed it in 1586. During the Tokugawa Shogunate (1600-1868), when Japan was secluded from the rest of the world, the only foreign physicians allowed to enter Japan were those employed by the Dutch factory at Dejima in Nagasaki. Only four of those physicians left behind seeds for the foundation of Western medicine in Japan, namely Caspar Schambergen, who founded a Japanese school of surgery in 1650; Engelbert Kämpfer, who visited Japan in 1691 to 1692; Carl Peter Thunberg, who botanically explored Japan in 1775 to 1776; and Philipp Franz Balthasar von Siebold, who practiced medicine in Nagasaki in 1823 to 1829 and 1859 to 1861. On the whole, Western medicine and surgery never established a real foothold in Japan until the fall of the shogunate and the restoration of the emperor in 1868.

    Full Text Available Guava decline, caused by the interaction between the phytonematode Meloidogyne enterolobii and the fungus Fusarium solani, has caused direct and indirect losses to the whole productive chain of guava. Aiming to understand the interaction mechanisms between M. enterolobii and F. solani, this study carried out a bioassay on guava plants with roots in two different treatments: inoculated separatelyor together with the fungus and/or nematode. The nematode parasitism not triggered an systemic effect on the plant become susceptible to root rot caused by the fungus.Therefore, it was concluded that there was a local effect of parasitism by M. enterolobii on the pathogenicity of F. solani in guava roots, making it necessary for the two pathogens to occupy the same space at the same time for occurrence of guava decline.

    The porous Fe{sub 2}O{sub 3} was synthesized chemically. The average size of the particle was {approx}85.0 nm, which was observed by scanning electron microscopy. The signature of porous structure was confirmed by a N{sub 2} adsorption/desorption isotherm and intense x-ray powder diffraction peak at low angle. The x-ray diffraction pattern at high angle indicates the amorphous structure. Moessbauer investigations show that the value of the hyperfine field is {approx}498.0 kOe at 4.2 K which is much smaller than that of the hyperfine field of crystalline {alpha}/{gamma}-Fe{sub 2}O{sub 3} and consistent with the values of amorphous Fe{sub 2}O{sub 3}. The temperature dependence of zero-field cooled magnetization exhibits a peak at 18.0 K (T{sub f}), where T{sub f} follows the Almeida-Thouless relation as T{sub f} {proportional_to} H{sup 2/3}. The ageing phenomenon of the magnetic relaxation below T{sub f} and the memory effect in the field-cooled magnetization indicate the typical features of the classical spin-glass compounds below the spin freezing temperature at T{sub f}.

    Full Text Available We collected and analyzed 286 Barn owl, Tyto alba (Scopoli, 1769, pellets from two nests in different environments along the mid-Araguaia River in central Brazil. Our analyses revealed that these owls feed mainly on small mammals, especially rodents. Owls from the riverbanks at Fazenda Santa Fé had a more diverse diet, preying mainly on rodents that typically inhabit riparian grasslands - Holochilus sciureus Wagner, 1842 - and forests - Hylaeamys megacephalus (Fischer, 1814 and Oecomys spp., which probably also occur in forest borders or clearings. On the other hand, owls from an agroecosystem at Fazenda Lago Verde preyed mostly on rodent species common in these agrarian fields, Calomys tocantinsi Bonvicino, Lima & Almeida, 2003. Additionally, we compared small mammal richness estimates based on the analysis of owl pellets with estimates from live-trapping in the same areas. Owl pellets revealed two rodent species undetected by live traps - Euryoryzomys sp. and Rattus rattus (Linnaeus, 1758 - and four rodent species were trapped, but not found in owl pellets - Oecomys roberti Thomas, 1904, Pseudoryzomys simplex (Winge, 1887, Rhipidomys ipukensis Rocha, B.M.A. Costa & L.P. Costa, 2011, and Makalata didelphoides (Desmarest, 1817. Traps yielded higher species richness, but these two methods complement each other for surveying small rodents.

    Full Text Available Among the Corporate Governance mechanisms, the Board of Directors is mentioned in academic research as fundamental in company performance and values in different countries. The important role in defense of the stockholders’ rights, preventing the managers from using the company in defense of their own interests, makes this a relevant mechanism in empirical research, even more when its relations with financial indicators is analyzed. In this study, the main objective was to analyze the relation between this mechanism and the value, performance and risk of Brazilian companies in 2012 and 2013, using panel data regression. Therefore, a Board of Directors index was created, based on binary questions, adapted from Silva, Santos and Almeida (2011, to be used as an independent variable in econometric models. A positive statistical relation was found between the proposed inedex and the variable Volatility, against expectations. The research also indicated relevant relations between the dependent and control variables. Among other results, it was concluded that: a positive relation exists between the company size and its performance; a positive relation exists between the growth of sales and the company value; a position relation between the risk variables beta and volatility; and belonging to the distinguished corporate governance levels on the stock exchange reduces the volatility of company stocks.

    Full text: Compound quantum-dots (QDs) are promising materials used in many fields of technological development. In spite of that, the accurate knowledge of their compositional depth-profiling is still a technological challenge. Recently, we used the MEIS (medium energy ion-scattering) technique, combined with PIXE and RBS (Rutherford backscattering spectrometry) to characterize core-shell nanostructures of CdSe/ZnS [1]. In this work, we use the same characterization methods to survey the changes of elemental distribution in the the core and shell regions of these QDs, when submitted to a range of thermal treatments and proton irradiation conditions. Our preliminary results show that for temperatures below the melting point of the bulk CdSe compound, there is already a decrease in the amount of cadmium, accompanied by an overall decrease in the diameter of the CdSe QD nuclei.

Tellez-Zenteno1, Cesar Serrano-Almeida2, Farzad Moien-Afshari11Division of Neurology, University of Saskatchewan, Saskatoon, Saskatchewan, Canada; 2Department of Clinical Neurosciences, University of Calgary, Calgary, Alberta, CanadaAbstract: Gelastic seizures are epileptic events characterized by bouts of laughter. Laughter-like vocalization is usually combined with facial contraction in the form of a smile. Autonomic features such as flushing, tachycardia, and altered respiration are widely recognized. Conscious state may not be impaired, although this is often difficult to asses particularly in young children. Gelastic seizures have been associated classically to hypothalamic hamartomas, although different extrahypothalamic localizations have been described. Hypothalamic hamartomas are rare congenital lesions presenting with the classic triad of gelastic epilepsy, precocious puberty and developmental delay. The clinical course of patients with gelastic seizures associated with hypothalamic hamartomas is progressive, commencing with gelastic seizures in infancy, deteriorating into more complex seizure disorder resulting in intractable epilepsy. Electrophysiological, radiological, and pathophysiological studies have confirmed the intrinsic epileptogenicity of the hypothalamic hamartoma. Currently the most effective surgical approach is the trancallosal anterior interforniceal approach, however newer approaches including the endoscopic and other treatment such as radiosurgery and gamma knife have been used with success. This review focuses on the syndrome of gelastic seizures associated with hypothalamic hamartomas, but it also reviews other concepts such as status gelasticus and some aspects of gelastic seizures in other locations.Keywords: epilepsy, gelastic seizures, epilepsy surgery, hypothalamic hamartoma, intractable epilepsy

    The Somuncurá Plateau is a Protected Natural Area located in the middle of the northern extra-Andean arid Patagonia. Inhabited by at least 20 small mammal species, is the place with the uppermost species richness in Patagonia. The aim of this study was to examine the parasite remains from micromammal coprolites collected in association with a bone sequence recovered at the east of the Somuncurá Plateau (site "Alero Las Lechuzas"). Coprolites came from the four temporal units previously defined: unit I (4790 ± 100 yrs. 14 C B.P.), unit II, unit III (7840 ± 120 yrs. 14 C B.P.) and unit IV. Each coprolite was processed, rehydrated, homogenized, processed by spontaneous sedimentation and examined using a light microscope. Coprolites and eggs were described, measured and photographed. Samples were positive for two nematode species: Helminthoxys caudatus Freitas, Lent & Almeida, 1937 (Oxyurida, Oxyuridae) and Trichuris spp. (Trichinellida: Trichuridae). This is the first paleoparasitological study developed for the Somuncurá Plateau Protected Area. Moreover, this is the first time that the genus Helminthoxys is reported from ancient times worldwide. Coprolites were attributed to the mountain cavy Microcavia australis (Rodentia, Caviidae).The presence of H. caudatus for the Middle Holocene of northern Patagonia contributes to the study of the history of the histricomorphs and pinworms relationships.

This work has as main subject, to diagnose and to value the environmental impacts that occurred and can occur in the future on the brooks and springs where there were Pipeline Bolivia Mato-Grosso interference on its crossing at the Serrana area, in Caceres municipality. The springs monitor were done during 18 months (march, 2001 to September, 2001), during and after the ending of the works, including different climates and hydrologic conditions, making it possible to diagnose and to value the draining behavior on the drought and on the overflow epoch. So, we believe that the knowledge about the interferences, risks and alterations that reflects on the fluvial duct of the sub-basin that drains the Serrana Province and leaks to Paraguay River may be contributing indirectly or directly to the Pantanal conservation.

    1990-01-01

    This volume contains papers which, for the most part, are based on talks given at an international conference on Lattices, Semigroups, and Universal Algebra that was held in Lisbon, Portugal during the week of June 20-24, 1988. The conference was dedicated to the memory of Professor Antonio Almeida Costa, a Portuguese mathematician who greatly contributed to the development of th algebra in Portugal, on the 10 anniversary of his death. The themes of the conference reflect some of his research interests and those of his students. The purpose of the conference was to gather leading experts in Lattices, Semigroups, and Universal Algebra and to promote a discussion of recent developments and trends in these areas. All three fields have grown rapidly during the last few decades with varying degrees of interaction. Lattice theory and Universal Algebra have historically evolved alongside with a large overlap between the groups of researchers in the two fields. More recently, techniques and ideas of these theories ha...

Coronary angiography revealed a right coronary artery originating from the trunk of the left coronary artery, and an aortic coarctation was observed on aortography. A CT angiogram confirmed these findings. Resection of the aortic coarctation and reimplantation of the ostial portion of right coronary artery into its native site was performed, and resulted in a satisfactory outcome. The association of an anomalous right coronary artery with aortic coarctation has rarely been described and represents a critical situation where early diagnosis and prompt intervention are essential.Keywords: coronary anomalies, single ostium, myocardial ischemia, angina pectoris

    Full Text Available The present study aimed to document the effects of financial constraints on the negative relationship between cash flow and external funds, a phenomenon associated with the Pecking Order Theory. This theory suggests that companies subject to more expensive external funds (financially constrained firms should demonstrate a stronger negative relationship with cash flow than companies subject to minor financial frictions (financially unconstrained firms. The results indicate that the external funds of constrained firms consistently present less negative sensitivity to cash flow compared with those of unconstrained companies. Additionally, the internal funds of constrained companies demonstrate a positive sensitivity to cash flow, whereas those of unconstrained companies do not show any such significant behavior. These results are in accordance with the findings of Almeida and Campello (2010, who suggest the following: first, because of the endogenous nature of investment decisions in constrained companies, the complementary relationship between internal and external funds prevails over the substitutive effects suggested by the Pecking Order Theory; and second, the negative relationship between cash flow and external funds cannot be interpreted as evidence of costly external funds and therefore does not corroborate the Pecking Order Theory.

    Full Text Available Recently LED (Lighting Emitting Diode lighting sources are applied not only for displays like LED BLU (back light unit TV but also for general lighting like LED lamps for home and office. The color temperature, or chromaticity, and brightness of LED lighting can be easily controlled. Preferred combinations between illuminance and color temperature of lighting depend on daily living activities (Oi et al., 2007 Symposium on Design of Artificial Environments 214–215. Changes in intensity can be more easily detected than color changes (Almeida et al., 2009 Perception 38 1109–1117. We investigated whether the illumination stimuli of LED lighting can enhance attention and relaxation level by controlling color temperature and illuminance according to activities. EEG signals are used to estimate attention and relaxation levels of human subjects under different lighting conditions. Nine participants with normal eye sight and color vision participated in the experiments with four different activities under different illumination conditions. LED lighting with color temperature 3600 K in 240 lux is used for relaxation activities, and LED lighting with 6600 K in 794 lux is used for the task which requires attention. These lighting conditions are compared with conventional lighting condition with 4600 K in 530 lux. Preliminary experiment results show that low color temperature with low illumination intensity of LED lighting enhances relaxation level and high color temperature with high illuminance improves attention level compared with conventional lighting environment without illuminance and color temperature changes.

  17. Equilibrium and nonequilibrium properties of Boolean decision problems on scale-free graphs with competing interactions with external biases

    2013-03-01

    We study the equilibrium and nonequilibrium properties of Boolean decision problems with competing interactions on scale-free graphs in a magnetic field. Previous studies at zero field have shown a remarkable equilibrium stability of Boolean variables (Ising spins) with competing interactions (spin glasses) on scale-free networks. When the exponent that describes the power-law decay of the connectivity of the network is strictly larger than 3, the system undergoes a spin-glass transition. However, when the exponent is equal to or less than 3, the glass phase is stable for all temperatures. First we perform finite-temperature Monte Carlo simulations in a field to test the robustness of the spin-glass phase and show, in agreement with analytical calculations, that the system exhibits a de Almeida-Thouless line. Furthermore, we study avalanches in the system at zero temperature to see if the system displays self-organized criticality. This would suggest that damage (avalanches) can spread across the whole system with nonzero probability, i.e., that Boolean decision problems on scale-free networks with competing interactions are fragile when not in thermal equilibrium.

Numerical results suggest that avalanches (damage) can spread across the whole system with nonzero probability when the decay exponent of the interaction degree is less than or equal to 2, i.e., that Boolean decision problems on scale-free networks with competing interactions can be fragile when not in thermal equilibrium.

    The Low Energy Particle Track Simulation (LEPTS) procedure is a powerful complementary tool to include the effect of low energy electrons and positrons in medical applications of radiation. In particular, for ion-beam cancer treatments provides a detailed description of the role of the secondary electrons abundantly generated around the Bragg peak as well as the possibility of using transmuted positron emitters (C11, O15) as a complement for ion-beam dosimetry. In this study we present interaction probability data derived from IAM-SCAR corrective factors for liquid environments. Using these data, single electron and positron tracks in liquid water and pyrimidine have been simulated providing information about energy deposition as well as the number and type of interactions taking place in any selected ``nanovolume'' of the irradiated area.

    Full Text Available O presente estudo investigou se as companhias brasileiras de capital aberto, entre 1995 e 2008, coordenam as políticas de caixa e dívida para efeitos de hedging contra subinvestimento em condições de restrição financeira. Os resultados indicam a inexistência de um componente de hedging usando, simultaneamente, as políticas de caixa e dívida em companhias restritas. Foi observada para as companhias restritas financeiramente uma sensibilidade positiva do caixa ao fluxo de caixa e sensibilidade negativa da dívida ao fluxo de caixa, independentemente da necessidade de hedging. As companhias irrestritas não apresentaram uma sensibilidade do caixa ao fluxo de caixa significante estatisticamente, mas apresentaram sensibilidade negativa da dívida ao fluxo de caixa, resultados também independentes da necessidade de hedging. As evidências contrariam os resultados encontrados por Acharya, Almeida e Campello (2007 no mercado norte-americano, onde caixa e dívida negativa apresentaram de acordo com a necessidade de hedging diferentes papéis na otimização intertemporal dos investimentos em companhias restritas.

    Full Text Available Seguindo Almeida, Campello e Weisbach (2003, usamos a relação entre restrição de crédito e a demanda por liquidez para mensurar o efeito das restrições crédito sobre as políticas das empresas brasileiras. O efeito da restrição de crédito pode ser capturado via propensão à poupança de fundos líquidos extraordinários. Enquanto empresas que enfrentam restrições de crédito deveriam apresentar uma sensibilidade positiva à entrada de recursos extraordinários em seu fluxo de caixa, as empresas irrestritas não apresentariam qualquer relação neste sentido. Utilizando o método 2SLS, estimamos a sensibilidade do fluxo de caixa à receitas extraordinárias usando uma amostra de empresas brasileiras entre 1995 e 2007 e, utilizando o acesso ao mercado financeiro internacional através de ADRs, verificamos que as empresas restritas financeiramente apresentam uma sensibilidade positiva do fluxo de caixa à recursos extraordinários, enquanto as empresas irrestritas não se comportam da mesma forma.

With such information the Children Literacy Through Learning Sotfwares project took effective place in UFSC’s Colégio de Aplicação school, using Mestre® (GOYOS e ALMEIDA, 1994. Five students, indicated by their teacher due to their difficulties in class to benefit from the project, were assisted in their literacy, being one of them with only impaired hearing, who benefited for being encouraged to develop auditory identification strategies. All of them developed motivational autonomy throughout the project, feeling more comfortable and motivated, always counting on their supervisors, who informed the teacher about each student’s performance while being observed. At the end of the project the teacher highlighted this program’s importance to child education, yet without making use of them herself. This project’s benefits have proven themselves necessary to those students’s development as individuals under learning process, allowing to acknowledge what  an educational software can do and must be in order to develop its potential as a  teaching tool, making the no-mistaking-learning advantages evident when it comes to respecting each student’s timing in learning.

    Full Text Available Are well evaluated mayors reelected or elect their peers? This article aims at testing the following hypothesis considering the Brazilian 2008 elections, presented by Almeida (2008: is a good government reelected or elects its supporters? The article presents the results of seven Brazilian capitals in 2008. At first I verify if there is a relationship between a well evaluated mayor administration and election success. I consider good administration as the causal variable that explains the victory of the candidate. However, when we analyze the election results from the seven capitals, other variable come up to explain the victory of the candidates in the elections. This means that the variable good administration when considered alone is not enough to explain the success of a political candidate. Using qualitative and quantitative research and developing a detailed analysis of election in Recife in 2008, this article concludes that the good administration variable affects the electoral success of a candidate. And that other variables also matter to explain the electoral victory of the candidate.

No presente artigo procurou-se avaliar de que maneira a Ortodontia brasileira foi dimensionada dentro do ensino oficial, se organizou em torno de suas associações de classe e qual literatura especializada estava à disposição de seus precursores. Precursores como Antônio Gonçalves Pereira da Silva, provavelmente o primeiro professor a ensinar a confecção de aparelhos ortodônticos; Carlos de Almeida Lustosa, o primeiro brasileiro a se tornar especialista em Ortodontia;. Carlos Alves da Costa, autor do primeiro livro-texto em Português totalmente dedicado à especialidade. Por outro lado, para que se pudesse perceber de que maneira essas mudanças foram acontecendo ao longo do tempo e correlacioná-las com as modificações em nível mundial, um resumo histórico da Ortodontia em seu universo geral foi organizado. De acordo com o que foi pesquisado, pode-se afirmar que foram necessários aproximadamente 50 anos para a consolidação dos centros de pós-graduação no Brasil. Também é verdade que o esforço das instituições de ensino e entidades de classe contribuiu para criar as bases do desenvolvimento científico da Ortodontia brasileira. No presente momento, entretanto, parece sensato supor que o próximo passo deverá ser o estabelecimento de normas que regulamentem a pós-graduação, de modo a aprimorar a formação profissional dos novos especialistas.Education, organization and literature.

The fact that European politics is mapped onto football in multimodal metaphors on this sports newspaper cover draws on the interplay of conceptual metaphors, respectively in the visual mode and in the written mode. Furthermore, there is a relevant time-bound leitmotif which motivates the mapping of politics onto football in the sports newspaper A Bola, namely the upcoming football match between Portugal and Germany. In the multimodal framing of the story line under analysis. The visual mode apparently assumes preponderance, since a picture of Angela Merkel, a prominent leader of EU, is clearly overshadowed by a large picture of Cristiano Ronaldo, the captain of the Portuguese National Football team. However, the visual modality of Cristiano Ronaldo’s dominance over Angela Merkel is intertwined with the powerful metaphorical headline “Vamos expulsar a Alemanha do Euro” (“Let’s kick Germany out of the European Championship”, intended to boost the courage of the Portuguese national football team: “Go Portugal – you can win this time!”. Thus, differently from multimodal metaphors on other covers of the same newspaper, the visual modality in this case cannot be considered the dominant factor in multimodal meaning creation in this politically-oriented layout.Keywords: Multimodal Metaphors.

    Hernando, D, Garatachea, N, Almeida, R, Casajús, JA, and Bailón, R. Validation of heart rate monitor Polar RS800 for heart rate variability analysis during exercise. J Strength Cond Res 32(3): 716-725, 2018-Heart rate variability (HRV) analysis during exercise is an interesting noninvasive tool to measure the cardiovascular response to the stress of exercise. Wearable heart rate monitors are a comfortable option to measure interbeat (RR) intervals while doing physical activities. It is necessary to evaluate the agreement between HRV parameters derived from the RR series recorded by wearable devices and those derived from an electrocardiogram (ECG) during dynamic exercise of low to high intensity. Twenty-three male volunteers performed an exercise stress test on a cycle ergometer. Subjects wore a Polar RS800 device, whereas ECG was also recorded simultaneously to extract the reference RR intervals. A time-frequency spectral analysis was performed to extract the instantaneous mean heart rate (HRM), and the power of low-frequency (PLF) and high-frequency (PHF) components, the latter centered on the respiratory frequency. Analysis was done in intervals of different exercise intensity based on oxygen consumption. Linear correlation, reliability, and agreement were computed in each interval. The agreement between the RR series obtained from the Polar device and from the ECG is high throughout the whole test although the shorter the RR is, the more differences there are. Both methods are interchangeable when analyzing HRV at rest. At high exercise intensity, HRM and PLF still presented a high correlation (ρ > 0.8) and excellent reliability and agreement indices (above 0.9). However, the PHF measurements from the Polar showed reliability and agreement coefficients around 0.5 or lower when the level of the exercise increases (for levels of O2 above 60%).

Among other oxides, doped BiNb(Ta)O 4 , ZnO , SnO 2 , WO 3 and TiO 2 have been identified as potential photocatalytic materials due to their appropriate band gap energies. We have used high quality materials as for instance by the citrate method according to reference [1], a modified ion beam assisted deposition technique [2] and as titanium dioxide nanotubes (TiO 2 -NTs) arrays synthesized by electrochemical anodization [3]. We present the optical properties spectra of these materials using the X-ray Photoelectron Spectroscopy (XPS), Ellipsometry and first principles approach by DFT respectively [1,2]. In this work, position of reduction and oxidation level with respect to the vacuum level are identified for these materials. We can conclude that some of them are good candidates for the production of hydrogen by splitting of water in the presence of sunlight and for efficient solar energy conversion as well. [1] C. G.

  20. Analysis of total visual and ccd v-broadband observation of comet c/1995 o1 (hale-bopp): 1995-2003

    The wealth of available information on total visual magnitudes and broadband-V CCD observations of the exceptionally bright Comet C/1995 O1 (Hale-Bopp) proved to be an excellent opportunity to test the Semi-Empirical Method of Visual Magnitudes (de Almeida, Singh & Huebner, 1997) for very bright comets. The main objective is to extend the method to include total visual magnitude observations obtained with CCD detector and V filter in our analysis of total visual magnitudes and obtain a single light curve. We compare the CCD V-broadband careful observations of Liller (1997) by plotting then together with the total visual magnitude observations from experienced visual observers found in the International Comet Quarterly (ICQ) archive. We find a nice agreement despite of the fact that CCDs and V filter passbands detect systematically more coma than visual observers, since they have different responses to C2, which is the main emission from the coma, and consequently they should be used with larger apperture diameters. A data set of ˜400 CCD selected observations covering about the same 5 years time span of the ˜12,000 ICQ total visual magnitude observations were used in the analysis. A least-squares fit to the values yielded a relation for water production rates vs heliocentric distances for the pre- and post-perihelion phases and are converted into gas production rates (in g/s) released by the nucleus. The dimension of the nucleus as well as its effective active area is determined and compared to other works.

  1. On the relationship between gas and dust in 15 comets: an application to Comet 103P/Hartley 2 target of the NASA EPOXI mission of opportunity

    Sanzovo, G. C.; Sanzovo, D. Trevisan; de Almeida, A. A.

    After the success of Deep Impact mission to hit the nucleus of Comet 9P/Tempel 1 with an impactor, the concerns are turned now to the possible reutilization of this dormant flyby spacecraft in the study of another comet, for only about 10% of the cost of the original mission. Comet 103P/Hartley 2 on UT 2010 October 11 is the most attractive target in terms of available fuel at rendezvous and arrival time at the comet. In addition, the comet has a low inclination so that major orbital plane changes in the spacecraft trajectory are unnecessary. In an effort to provide information concerning the planning of this new NASA EPOXI space mission of opportunity, we use in this work, visual magnitudes measurements available from International Comet Quarterly (ICQ) to obtain, applying the Semi-Empirical Method of Visual Magnitudes - SEMVM (de Almeida, Singh, & Huebner 1997), the water production rates (in molecules/s) related to its perihelion passage of 1997. When associated to the water vaporization theory of Delsemme (1982), these rates allowed the acquisition of the minimum dimension for the effective nuclear radius of the comet. The water production rates were then converted into gas production rates (in g/s) so that, with the help of the strong correlation between gas and dust found for 12 periodic comets and 3 non-period comets (Trevisan Sanzovo 2006), we obtained the dust loss rates (in g/s), its behavior with the heliocentric distance and the dust-to-gas ratios in this physically attractive rendezvous target-comet to Deep Impact spacecraft at a closest approach of 700 km.

    Bees play a key role in pollination and thereby help maintain plant diversity. The stingless bee Melipona scutellaris is an important pollinator in northeastern Brazil because it is endemic to this region. Both deforestation and timber harvesting have reduced the nesting sites for this species, thus reducing its population and range. Genetic studies may help reverse this process by providing important tools for their proper management with a view to conservation of this species. Microsatellite markers have proven to be ideal for mapping genes and population genetic studies. Our aim was to study, using microsatellite markers, the interpopulation genetic variability of M. scutellaris in different parts of the Recôncavo region in Bahia State, Brazil. In all, 95 adult workers from 11 localities in Recôncavo Baiano (Amargosa, Cabaceiras do Paraguaçu, Conceição da Feira, Conceição do Almeida, Domingos Macedo Costa, Governador Mangabeira, Jaguaripe, Jiquiriça, Maragojipe, São Felipe, and Vera Cruz) were analyzed using 10 pairs of microsatellite primers developed for different Meliponini species. The total number of alleles, allele richness, and genetic diversity ranged from 2 to 7 per locus (average = 4.4), 1.00 to 4.88, and 0.0 to 0.850, respectively. The expected and observed heterozygosities varied from 0.0 to 0.76 and 0.0 to 0.84, respectively. No locus showed deviation from the expected frequencies in the chi-square test or linkage disequilibrium. The fixation index, analysis of molecular variance, and unweighted pair-group method using the arithmetic average revealed the effects of human activities on the populations of M. scutellaris, as little genetic structure was detected.

  7. From magic to science: a journey throughout Latin American medical mycology.

    The start of Latin America's love story with fungi may be placed in pre-Hispanic times when the use of fungi in both ritual ceremonies and daily life were common to the native civilizations. But the medical mycology discipline in Latin America started at the end of the 19th Century. At that time, scholars such as A. Posadas, R. Seeber, A. Lutz and P. Almeida, discovered agents of fungal diseases, the study of which has influenced the regional research ever since. Heirs to them are the researchers that today thrive in regional Universities and Research Institutes. Two current initiatives improve cooperation among Latin American medical mycologists. First, the periodical organization of International Paracoccidioidomycosis Meetings (seven so far, from 1979 to 1999); second, the creation of the Latin American Association for Mycology in 1991 (three Congresses, from 1993 to 1999). Latin American publications have increased in international specialized journals such as that from our Society (ISHAM) (from 8% in 1967 to 19% in 1999), and the Iberoamerican Journal of Mycology (Revista Iberoamericana de Micologia; > 40% from 1997 to 1999). In addition, Latin American participation at ISHAM International Congresses has risen from 6.9% in 1975 to 21.3% in 1997, and 43.2% at the 14th ISHAM Congress, held for the first time in a Latin American country, Argentina. A significant contribution of women to the scientific establishment of Latin American medical mycology (e.g., 45% of Latin American papers vs. 18% of other regions published in Journal of Medical and Veterinary Mycology in 1987, had women as authors or coauthors) suggests a better academic consideration of Latin American women against their counterparts in the developed world. Taken together, all these figures reflect the enthusiasm of our Latin American colleagues in the field, despite the difficulties that afflict our region, and affect our work.

    The irreversibility properties of high-T c superconductors are of major importance for technological applications. For example, a high irreversibility magnetic field is a more desirable quality for a superconductor . The irreversibility line in the H-T plane is constituted by experimental points, which divides the irreversible and reversible behavior of the magnetization. The irreversibility lines for series of La 1.5+x Ba 1.5+x-y Ca y Cu 3 O z polycrystalline samples with different doping were investigated. The samples were synthesized using the usual solid estate reaction method. Rietveld-type refinement of x-ray diffraction patterns permitted to determine the crystallization of material in a tetragonal structure. Curves of magnetization ZFC-FC for the system La 1.5+x Ba 1.5+x-y Ca y Cu 3 O z , were measured in magnetic fields of the 10-20,000 Oe, and allowed to obtain the values for the irreversibility and critical temperatures. The data of irreversibility temperature allowed demarcating the irreversibility line, T irr (H). Two main lines are used for the interpretation of the irreversibility line: one of those which suppose that the vortexes are activated thermally and the other proposes that associated to T irr a phase transition occurs. The irreversibility line is described by a power law. The obtained results allow concluding that in the system La 1.5+x Ba 1.5+x-y Ca y Cu 3 O z a characteristic bend of the Almeida-Thouless (AT) tendency is dominant for low fields and a bend Gabay-Toulouse (GT) behavior for high magnetic fields. This feature of the irreversibility line has been reported as a characteristic of granular superconductors and it corroborates the topological effects of vortexes mentioned by several authors .

  11. Functional and Expression Analyses of the Pneumocystis MAT Genes Suggest Obligate Sexuality through Primary Homothallism within Host Lungs

    Full Text Available Fungi of the genus Pneumocystis are obligate parasites that colonize mammals’ lungs and are host species specific. Pneumocystis jirovecii and Pneumocystis carinii infect, respectively, humans and rats. They can turn into opportunistic pathogens in immunosuppressed hosts, causing severe pneumonia. Their cell cycle is poorly known, mainly because of the absence of an established method of culture in vitro. It is thought to include both asexual and sexual phases. Comparative genomic analysis suggested that their mode of sexual reproduction is primary homothallism involving a single mating type (MAT locus encompassing plus and minus genes (matMc, matMi, and matPi; Almeida et al., mBio 6:e02250-14, 2015. Thus, each strain would be capable of sexual reproduction alone (self-fertility. However, this is a working hypothesis derived from computational analyses that is, in addition, based on the genome sequences of single isolates. Here, we tested this hypothesis in the wet laboratory. The function of the P. jirovecii and P. carinii matMc genes was ascertained by restoration of sporulation in the corresponding mutant of fission yeast. Using PCR, we found the same single MAT locus in all P. jirovecii isolates and showed that all three MAT genes are often concomitantly expressed during pneumonia. Extensive homology searches did not identify other types of MAT transcription factors in the genomes or cis-acting motifs flanking the MAT locus that could have been involved in MAT switching or silencing. Our observations suggest that Pneumocystis sexuality through primary homothallism is obligate within host lungs to complete the cell cycle, i.e., produce asci necessary for airborne transmission to new hosts.

Locally extinct species are discussed (e.g. Harpy Eagle Harpia harpyja, as well as the ones that colonized landscapes created by men (e.g. pastures, agricultural areas. When discussing Atlantic Forest endemism, some species were shown not to be endemic to this biome. Because the north of Paraná is almost totally deforested, the presence of the forest remnants by itself conter them great importance for conservation, besides the existence of species endemic to the Atlantic Forest and considered to be under the threat of extinction. Conservation and management measures are also proposed.

    We investigate the supervised batch learning of Boolean functions expressed by a two-layer perceptron with a tree-like structure. We adopt continuous weights (spherical model) and the Gibbs algorithm. We study the Parity and And machines and two types of noise, input and output noise, together with the noiseless case. We assume that only the teacher suffers from noise. By using the replica method, we derive the saddle point equations for order parameters under the replica symmetric (RS) ansatz. We study the critical value αC of the loading rate α above which the learning phase exists for cases with and without noise. We find that αC is nonzero for the Parity machine, while it is zero for the And machine. We derive the exponents barβ of order parameters expressed as (α - α C)bar{β} when α is near to αC. Furthermore, in the Parity machine, when noise exists, we find a spin glass solution, in which the overlap between the teacher and student vectors is zero but that between student vectors is nonzero. We perform Markov chain Monte Carlo simulations by simulated annealing and also by exchange Monte Carlo simulations in both machines. In the Parity machine, we study the de Almeida-Thouless stability, and by comparing theoretical and numerical results, we find that there exist parameter regions where the RS solution is unstable, and that the spin glass solution is metastable or unstable. We also study asymptotic learning behavior for large α and derive the exponents hat{β } of order parameters expressed as α - hat{β } when α is large in both machines. By simulated annealing simulations, we confirm these results and conclude that learning takes place for the input noise case with any noise amplitude and for the output noise case when the probability that the teacher's output is reversed is less than one-half.

E-mail: fabiana.lessa@gmail.com The aim of this study was to investigate the role of Rhipicephalus sanguineus, the brown dog tick, in the transmission of Leishmania infantum. To accomplish this, we used 24 adult golden hamsters of both genders, and divided them into two groups: a control group (n = 4 and an experimental group (n = 20. The animals from the experimental group were infested with ticks obtained from dogs naturally infected with L. infantum. Hamsters of the control group were not infested and were maintained at the same conditions, as the infested animals. After three months of observation, animals were euthanized and they were posted to obtain samples of their blood, spleen, liver, lymph nodes, and skin. These samples were then processed by histopathology, immunohistochemistry, and polymerase chain reaction (PCR. Fourteen hamsters (70% of the experimental group tested PCR-positive for L. infantum DNA in samples of buffy coat. The results of this study indicated that R. sanguineus ticks can transmit some forms or parts of L. infantum to parasitized hamsters.

    We have studied the magnetic behavior of YMn{sub 1−x}Fe{sub x}O{sub 3} (x=0 and 0.2) nanoparticles synthesized by conventional solid state reaction method. The as-synthesized nanoparticles were found to have hexagonal phase with P6{sub 3cm} space group confirmed by X-Ray diffraction. The particle size was found to be ~70 nm as confirmed by both X-Ray diffraction and Transmission Electron Microscopy. DC magnetization and memory effect measurements imply that the h-YMnO{sub 3} nanoparticles bear a resemblance to super spin-glass state following de Almeida–Thouless like behavior which is being suppressed by Fe-doping. The Fe-doping in YMnO{sub 3} enhances the antiferromagnetic (AFM) transition temperature T{sub N} to ~79 K and induces a new magnetic state due to the surface spins which is realized as diluted antiferromagnet in a field (DAFF) as explored by the thermoremanent and isothermoremanent magnetization measured with different applied magnetic field. - Highlights: • Magnetic behavior of h-YMn{sub 1−x}Fe{sub x}O{sub 3} (x=0 and 0.2) nanoparticles have been studied. • The nanoparticles (~70 nm) were synthesized by solid state reaction method. • Magnetic data reveal spin-glass behavior in YMnO{sub 3} which was suppressed in YMn{sub 0.8}Fe{sub 0.2}O{sub 3}. • The h-YMnO{sub 3} nanoparticles show memory effect and obey de-Almeida Thouless line. • TRM and IRM suggest spin glass nature for YMnO{sub 3}, while the YMn{sub 0.8}Fe{sub 0.2}O{sub 3} resembles DAFF.

Eleven months earlier, the patient had undergone cardiac surgery because of an aortic root dilatation and bicuspid aortic valve with severe regurgitation secondary to infectious endocarditis by Coxiela burnetii and coronary artery disease in the left circumflex coronary artery. Then, a prosthesis valve and a saphenous bypass graft to the left circumflex coronary artery were placed. The patient was admitted to the Cardiology Department of Hospital Universitario de Canarias, Tenerife, Spain and a transthoracic echocardiography was performed that showed severe paraprosthetic aortic regurgitation and an aortic pseudoaneurysm. The 64-slice multidetector computed tomography confirmed the pseudoaneurysm, originating from the right sinus of Valsalva, with a compression of the native right coronary artery and a normal saphenous bypass graft. On the basis of these findings, we performed surgical treatment with a favorable postoperative evolution. In our case, results from complementary cardiac imaging techniques were crucial for patient management. The multidetector computed tomography allowed for a confident diagnosis of an unusual mechanism of coronary ischemia.

Estadual Paulista, Araraquara, Sao Paulo, Brazil Abstract: Invasive mycoses are a major problem for immunocompromised individuals and patients in intensive care units. Morbidity and mortality rates of these infections are high because of late diagnosis and delayed treatment. Moreover, the number of available antifungal agents is low, and there are problems with toxicity and resistance. Alternatives for treating invasive fungal infections are necessary. Nanostructured systems could be excellent carriers for antifungal drugs, reducing toxicity and targeting their action. The use of nanostructured systems for antifungal therapy began in the 1990s, with the appearance of lipid formulations of amphotericin B. This review encompasses different antifungal drug delivery systems, such as liposomes, carriers based on solid lipids and nanostructure lipids, polymeric nanoparticles, dendrimers, and others. All these delivery systems have advantages and disadvantages. Main advantages are the improvement in the antifungal properties, such as bioavailability, reduction in toxicity, and target tissue, which facilitates innovative therapeutic techniques. Conversely, a major disadvantage is the high cost of production. In the near future, the use of nanosystems for drug delivery strategies can be used for delivering peptides, including mucoadhesive systems for the treatment of oral and vaginal candidiasis.

    The Tocantins Province (Almeida et al. 1981) in central Brazil is a Neoproterozoic orogenic zone developed between the Amazon and Sao Francisco cratons and possibly a third continental block, known as Parapanema Block, hidden below the sedimentary rocks of the Parana Basin. The Tocantins Province comprises the eastward vergent Brasilia Belt, adjacent to the Sao Francisco Craton (Marini et al. 1984), and the westward vergent Paraguay and Araguaia belts, developed on the eastern margin of the Amazon Craton. According to Trompette (1997), the Brasilia and Araguaia belts had sedimentation starting at around 1.1-1.0 Ga and final closure at 0.6 Ga. In the northern part of the Brasilia Belt occur the Barro Alto, Canabrava and Niquelandia maficultramafic layered complexes. Inconclusive U-Pb isotopic data indicate ages between ca. 1600 and 2000 Ma for these intrusions that were affected by highgrade metamorphism ca. 740-790 Ma ago, during the Neoproterozoic (Ferreira Filho et al. 1994; Suita et al. 1994; Correia et al. 1997). In the southern part of the Brasilia Belt, in central Goias , is the Anapolis-Itaucu granulite complex. It consists of a large complex of high-grade rocks, volcano-sedimentary sequences and granites, exposed in between metasediments of the Araxa Group, the main constituent of the internal zone of the Neoproterozoic Brasilia Belt (Fuck et al. 1994). These granulites have traditionally been interpreted as the exposure of Archean sialic basement to the sediments of the Brasilia Belt (Danni et al. 1982, Marini et al. 1984; Lacerda Filho and Oliveira 1995). This work reports the results of a regional Sm- Nd isotopic investigation and U-Pb SHRIMP data in order to assess (i) the nature of the protoliths of the Araxa Group in this area; (ii) the nature and the high grade metamorphism of rocks from Anapolis-Itaucu Complex; (iii) the crystallization and metamorphism of aluminous granites (au)

    This project utilizes Tropical Rainfall Measuring Mission (TRMM) and Landsat satellite data to assess the impact of sea breeze precipitation upon areas of agricultural land use in southern Florida. Water is a critical resource to agriculture, and the availability of water for agricultural use in Florida continues to remain a key issue. Recent projections of statewide water use by 2020 estimate that 9.3 billion gallons of water per day will be demanded, and agriculture represents 47% of this demand (Bronson 2003). Farmers have fewer options for water supplies than public users and are often limited to using available supplies from surface and ground water sources which depend in part upon variable weather patterns. Sea breeze thunderstorms are responsible for much of the rainfall delivered to Florida during the wet season (May-October) and have been recognized as an important overall contributor of rainfall in southern Florida (Almeida 2003). TRMM satellite data was used to analyze how sea breeze-induced thunderstorms during El Nino and La Nina affected interannual patterns of precipitation in southern Florida from 1998-2009. TRMM's Precipitation Radar and Microwave Imager provide data to quantify water vapor in the atmosphere, precipitation rates and intensity, and the distribution of precipitation. Rainfall accumulation data derived from TRMM and other microwave sensors were used to analyze the temporal and spatial variations of rainfall during each phase of the El Nino Southern Oscillation (ENSO). Through the use of TRMM and Landsat, slight variations were observed, but it was determined that neither sea breeze nor total rainfall patterns in South Florida were strongly affected by ENSO during the study period. However, more research is needed to characterize the influence of ENSO on summer weather patterns in South Florida. This research will provide the basis for continued observations and study with the Global Precipitation Measurement Mission.

    Magnetic properties of the Pr{sub 0.8}Sr{sub 0.2}MnO{sub 3} and Pr{sub 0.6}Sr{sub 0.4}MnO{sub 3} polycrystalline films have been studied using temperature and magnetic field dependences of the static magnetization and X-ray magnetic circular dichroism (XMCD) spectroscopy. For the both compositions, the difference between the temperature dependences of magnetization obtained in the zero fields cooling (ZFC) and field cooling (FC) modes has been revealed. The ZFC curves demonstrate a pronounced maximum at temperature T{sub m}. It is shown that the T{sub m} value dependence on the magnetic field follows the Almeida-Thouless line typical for the classic spin glass, what allows us to assume the possible spin-glass behavior of the films. Effect of the disorder in a direction of the crystallites easy-axis on the difference between FC and ZFC curves has been discussed also. Magnetic field dependences of the sample magnetization are presented by the hysteresis loops with the shape changing upon temperature variation. This behavior has been attributed to the effect of crystallographic anisotropy and Pr ions. The spectra and magnetic field dependences of XMCD at the Pr L{sub 2}- and Mn K-edges have been studied at 90 K. The magnetic field dependences of the XMCD at the Pr L{sub 2}-edge had shown Van Vleck paramagnetism from Pr{sup 3+} ions. - Highlights: • M (T) magnetization behavior indicates the presence of spin glass behavior in the films. • Shape of the hysteresis loops depends on temperature. • Magnetic field dependences of XMCD at T=90 K reveal Van Vleck paramagnetism from Pr{sup 3+} ions.

    Reliable, cost-effective, and gold-standard absolute quantification of non-esterified cholesterol in human plasma is of paramount importance in clinical lipidomics and for the monitoring of metabolic health. Here, we compared the performance of three mass spectrometric approaches available for direct detection and quantification of cholesterol in extracts of human plasma. These approaches are high resolution full scan Fourier transform mass spectrometry (FTMS) analysis, parallel reaction monitoring (PRM), and novel multiplexed MS/MS (MSX) technology, where fragments from selected precursor ions are detected simultaneously. Evaluating the performance of these approaches in terms of dynamic quantification range, linearity, and analytical precision showed that the MSX-based approach is superior to that of the FTMS and PRM-based approaches. To further show the efficacy of this approach, we devised a simple routine for extensive plasma lipidome characterization using only 8 μL of plasma, using a new commercially available ready-to-spike-in mixture with 14 synthetic lipid standards, and executing a single 6 min sample injection with combined MSX analysis for cholesterol quantification and FTMS analysis for quantification of sterol esters, glycerolipids, glycerophospholipids, and sphingolipids. Using this simple routine afforded reproducible and absolute quantification of 200 lipid species encompassing 13 lipid classes in human plasma samples. Notably, the analysis time of this procedure can be shortened for high throughput-oriented clinical lipidomics studies or extended with more advanced MSALL technology (Almeida R. et al., J. Am. Soc. Mass Spectrom. 26, 133-148 [1]) to support in-depth structural elucidation of lipid molecules. [Figure not available: see fulltext.

The aim of this study was to obtain and characterize an extract of Libidibia ferrea, ex Caesalpinia ferrea L. and to evaluate its feasibility for formulation as a mouthwash, according to current legislation. For this purpose, pH, sedimentation, density, and stability were evaluated, along with microbiological testing of the extract. The microbiological test was used to verify the presence of Staphylococcus aureus, Pseudomonas aeruginosa, fungi, yeasts, coliforms, and minimum inhibitory concentrations of Streptococcus mutans and Streptococcus oralis strains. Characterization, microbiological evaluation, and minimum inhibitory concentration results were tabulated and described using descriptive statistics. The L. ferrea extract showed stable characteristics, product quality, and antibacterial activity against the microorganisms tested irrespective of experimental time intervals. According to these results, it can be concluded that formulation of a mouthwash containing L. ferrea extract to control biofilm is feasible, but further studies are needed.Keywords: biofilm, extract, quality control

    We conducted a field study to determine seasonal egg parasitism rates of the kudzu bug Megacopta cribraria (F.) on the kudzu plant, Pueraria montana (Lour.) Merr. var. lobata (Willd.) Maesen et Almeida ex Sanjappa and Pradeep, in Tokyo, Japan, during the period from May 2014 to September 2014. The eggs of M. cribraria per 1 m2 of kudzu at four locations in Tokyo were collected weekly and parasitism rates were assessed. Eggs of M. cribraria were laid on the kudzu plant from May to September. Megacopta cribraria eggs were parasitized by two parasitoid species, Paratelenomus saccharalis (Dodd) and Ooencyrtus nezarae Ishii. Paratelenomus saccharalis first appeared in May, and its parasitism rates peaked in July and September. Ooencyrtus nezarae first appeared in June and its parasitism rates peaked in July. Except for one location which could not be statistically analyzed because of the small sample size, occurrence of parasitism by P. saccharalis and O. nezarae in M. cribraria egg masses was independent at one location and positively associated at two locations, suggesting that the use of host egg masses by P. saccharalis and O. nezarae is not mutually exclusive. Parasitism rates by P. saccharalis and O. nezarae were significantly lower for egg masses parasitized by both species than for those parasitized by a single species. The proportion of males among O. nezarae progeny was significantly higher for egg masses parasitized by O. nezarae together with P. saccharalis than for those parasitized by O. nezarae alone. These results suggest that parasitism of host egg masses by the two species is influenced by their interspecific interactions. © The Authors 2017.

    Full Text Available Since von Hibler gas grangrene has been considered a local infection with systemic symptoms. When we consider some of the symptoms of gas gangrene, those of the central nervous system are in evidence beeing similar to those observed in tetanus and botulism. It is likely therefore that gas gangrene intoxication and the disease caused by it are of neurotoxic nature. With Almeida Cardoso and Araujo Costa we were able to demonstrate lesions in the central nervous system of animals wich had been intoxicated during a short period of time as well in those with intoxication of longer duration. In acute intoxication, after intracreneal inoculation, severe alterations were seen within 20 to 30 minutes in the cells of the spinal cord, specially in motor cells and also in some cells of the posterior cord and spinal bulb. The changes consisted in chromatolysis and picnosis and were more marked in animals intoxicated with Clostridium histolyticum and Cl. perfringens toxines. Myelin sheet was unchanged. in delayed intoxication with greater and repeated dosis lesions of the central nervous system (brain, protuberance, medula ablongate and medula spinal were observed. They consisted in hyperemia, perivascular hemorrages in white and grey substances, oedema, accumulation of glia cells with enlarged and hyperchromatic nuclei, fragmentation of the myelin sheet and balooning degeneration of the described by Spielmeyer. Such changes were found in the swollen and hemorragic zones and were generally similar to those found in the acute type of Spielmeyer 9acute swelling and liquefation. Other changes found sometimes were agglutination of Nissl's bodies, sinous appearence of the dendritic endings, shruncken cells of Spielmeyer and neuronophagy around "ghost" cells.

    Brazil adopts an educational inclusion policy, which is based on the insertion of students with special needs in the elementary and high school. In the State of São Paulo, Brazil, visually impaired students, who attend public schools, receive books adapted for blind and low sighted individuals, so they can participate on Geography classes. This paper presents the results of the analysis of the enlarged material adapted to braille used at the elementary school. The analysis was based on the principle of the graphical semiology developed by ALMEIDA (2015), which discusses the use of alternative materials in order to represent areas, lines and dots with different heights, textures and shapes. The results were obtained through interviews, surveys and evaluation of teachers and students, who somehow experience the specificities of the visually impaired students daily. We observed that the adapted books do not bring all information contained in the original versions of the books and some of the exercises are not presented. Furthermore we could notice that the teachers and other students do not have any level of proficiency in understanding braille, which can hamper the interaction between visually impaired and the other students. After the observations, we adapted 22 maps using colored materials and handcraft techniques taking in-to account the different needs of the low sighted audience. The materials used are easy to be found and purchased, since they have a low cost. Using this alternative material we achieved a learning that was representative to all students and to the teachers, providing the socialization of the acquired knowledge.

    We have studied the magnetic behavior of YMn 1−x Fe x O 3 (x=0 and 0.2) nanoparticles synthesized by conventional solid state reaction method. The as-synthesized nanoparticles were found to have hexagonal phase with P6 3cm space group confirmed by X-Ray diffraction. The particle size was found to be ~70 nm as confirmed by both X-Ray diffraction and Transmission Electron Microscopy. DC magnetization and memory effect measurements imply that the h-YMnO 3 nanoparticles bear a resemblance to super spin-glass state following de Almeida–Thouless like behavior which is being suppressed by Fe-doping. The Fe-doping in YMnO 3 enhances the antiferromagnetic (AFM) transition temperature T N to ~79 K and induces a new magnetic state due to the surface spins which is realized as diluted antiferromagnet in a field (DAFF) as explored by the thermoremanent and isothermoremanent magnetization measured with different applied magnetic field. - Highlights: • Magnetic behavior of h-YMn 1−x Fe x O 3 (x=0 and 0.2) nanoparticles have been studied. • The nanoparticles (~70 nm) were synthesized by solid state reaction method. • Magnetic data reveal spin-glass behavior in YMnO 3 which was suppressed in YMn 0.8 Fe 0.2 O 3 . • The h-YMnO 3 nanoparticles show memory effect and obey de-Almeida Thouless line. • TRM and IRM suggest spin glass nature for YMnO 3 , while the YMn 0.8 Fe 0.2 O 3 resembles DAFF.

    Magnetic properties of the Pr 0.8 Sr 0.2 MnO 3 and Pr 0.6 Sr 0.4 MnO 3 polycrystalline films have been studied using temperature and magnetic field dependences of the static magnetization and X-ray magnetic circular dichroism (XMCD) spectroscopy. For the both compositions, the difference between the temperature dependences of magnetization obtained in the zero fields cooling (ZFC) and field cooling (FC) modes has been revealed. The ZFC curves demonstrate a pronounced maximum at temperature T m . It is shown that the T m value dependence on the magnetic field follows the Almeida-Thouless line typical for the classic spin glass, what allows us to assume the possible spin-glass behavior of the films. Effect of the disorder in a direction of the crystallites easy-axis on the difference between FC and ZFC curves has been discussed also. Magnetic field dependences of the sample magnetization are presented by the hysteresis loops with the shape changing upon temperature variation. This behavior has been attributed to the effect of crystallographic anisotropy and Pr ions. The spectra and magnetic field dependences of XMCD at the Pr L 2 - and Mn K-edges have been studied at 90 K. The magnetic field dependences of the XMCD at the Pr L 2 -edge had shown Van Vleck paramagnetism from Pr 3+ ions. - Highlights: • M (T) magnetization behavior indicates the presence of spin glass behavior in the films. • Shape of the hysteresis loops depends on temperature. • Magnetic field dependences of XMCD at T=90 K reveal Van Vleck paramagnetism from Pr 3+ ions.

Forty-three patients were randomized to weekly classes of singing practice, or handcraft work. They performed spirometry and completed maximal respiratory pressure measurements, evaluations of dyspnea, and the Saint George’s Respiratory Questionnaire, before and after 24 training classes. A functional evaluation, immediately after 10 minutes of singing practice, was also performed at the end of the study. Fifteen subjects completed the study in each group. In comparison to controls the singing group exhibited transitory elevations on the dyspnea Borg scale (p = 0.02, and inspiratory capacity (p = 0.01, and decreases of expiratory reserve volume (p = 0.03, just after a short session of singing. There was a significant difference on changes of maximal expiratory pressures in the comparison between groups at the end of training. While the control group showed deterioration of maximal expiratory pressure, the singing group exhibited a small improvement (p = 0.05. Both groups showed significant improvements of QoL in within group comparisons. We have concluded that singing classes are a well tolerated activity for selected subjects with COPD. Regular practice of singing may improve QoL, and preserve the maximal expiratory pressure of these patients.Keywords: COPD; pulmonary function tests; breathing exercises

  15. Extreme nonlinear terahertz electro-optics in diamond for ultrafast pulse switching

    Polarization switching of picosecond laser pulses is a fundamental concept in signal processing [C. Chen and G. Liu, Annu. Rev. Mater. Sci. 16, 203 (1986); V. R. Almeida et al., Nature 431, 1081 (2004); and A. A. P. Pohl et al., Photonics Sens. 3, 1 (2013)]. Conventional switching devices rely on the electro-optical Pockels effect and work at radio frequencies. The ensuing gating time of several nanoseconds is a bottleneck for faster switches which is set by the performance of state-of-the-art high-voltage electronics. Here we show that by substituting the electric field of several kV/cm provided by modern electronics by the MV/cm field of a single-cycle THz laser pulse, the electro-optical gating process can be driven orders of magnitude faster, at THz frequencies. In this context, we introduce diamond as an exceptional electro-optical material and demonstrate a pulse gating time as fast as 100 fs using sub-cycle THz-induced Kerr nonlinearity. We show that THz-induced switching in the insulator diamond is fully governed by the THz pulse shape. The presented THz-based electro-optical approach overcomes the bandwidth and switching speed limits of conventional MHz/GHz electronics and establishes the ultrafast electro-optical gating technology for the first time in the THz frequency range. We finally show that the presented THz polarization gating technique is applicable for advanced beam diagnostics. As a first example, we demonstrate tomographic reconstruction of a THz pulse in three dimensions.

    Full Text Available The objective of this study was to verify to what extent the cultural dimensions impact the accounting practice in Brazil. To do so, with regard to the cultural dimensions, we used the adapted questionnaire Valued Survey Model 08 (VSM 08, which Hofstede constructed in 2008, and its Portuguese version. In order to capture accounting practices, we applied the questionnaire structured with direct questions to accounting operators, originally used by Chanchani and Willett (2004 and replicated by Almeida and Lisboa (2011 and Karabinar, Canel and Öktem (2012. The final sample consisted of 449 respondents from all over Brazil, divided into the following groups of operators: accounting users, accounting teachers, accounting professionals and accounting students. Considering that there is a diversified number of variables to capture cultural dimensions and accounting practices, we used Exploratory Factor Analysis (EFA. The factors were extracted through Principal Component Analysis and Varimax extraction. After the factor analysis, a multiple regression was performed with the extracted factors, in which the dependent variable corresponded to the accounting practices, and the independent variables were the cultural dimensions. The results indicate that the accounting operators are mainly conservative and the cultural dimensions that most impact the accounting practice are aversion to uncertainty and distance from power. It was concluded that it is not possible to infer that, at first, the adoption of international accounting standards leads to an improvement in the accounting process, since the countries where these standards were originally conceived (common law tradition have a low aversion to uncertainty and distance from power, something contrary to the findings in this research.

  1. The use of Nd isotopes to establish sedimentary provenance at inverted passive margins: The case of Andrelandia depositional cycle at the Riberia belt, Brazil

    The Ribeira Belt (Almeida et al., 1973), in southeastern Brazil, is a Brasiliano/Pan-African belt that resulted from the agglutination of the Gondwana Supercontinent (750-500 Ma). The tectonic organization at its central segment can be defined by several tectono-stratigraphic domains (Heilbron et al., 1998, 2000). In general terms, each tectonic domain comprises: a) pre-1.8 Ga basement rocks; b) post-1.8 Ga metasedimentary cover including metabasic rocks of continental to MORB geochemical affinity; and c) Brasiliano-Pan African granitoids. U/Pb ages for zircon, titanite and monazite of both the pre-1.8 Ga basement and Brasiliano granitoids (Machado et al., 1996) reveal that basement gneisses were generated during the Transamazonian Orogeny, about 2.1 Ga. Peak metamorphic conditions (M1) of the Brasiliano Collage at the central Ribeira belt were reached at 590 - 565 Ma, with a second metamorphic event (M2) at 535 - 520 Ma (Machado et al., 1996). Our research area is located at the transition between the foreland and the hinterland of the Ribeira belt: the Occidental terrane. It represents a reworked margin of the Sao Francisco Craton, formerly known as a proterozoic tectonic plate. It is composed by two crustal scale thrust sheets (Andrelandia and Juiz de Fora domains) tangentially transported towards the foreland of Sao Francisco Craton. Despite the well-determined ages of the Transamazonic basement and Brasiliano granitic rocks (Machado et al. 1996), the sedimentary source of the siliciclastic cover at the Occidental terrane remains poorly known. In this case, the use of Nd isotopic system, due to its relative immobility, is an important additional tool of investigation in geological correlation between basement source areas and sedimentary cover. The siliciclastic sedimentary and metasedimentary rocks are formed by detritus of pre-existing crustal rocks and they could be formed by more than one source. Then, depleted mantle Nd model ages (T DM ) for sediments

    The Brasilia Belt is a large Neoproterozoic orogen formed along the western margin of the Sao Francisco/Congo Craton in central Brazil. It comprises: (i) a thick Meso-Neoproterozoic metasedimentary/sedimentary pile with eastward tectonic vergence; (ii) a large Neoproterozoic juvenile arc in the west (Goias Magmatic Arc); and (iii) a micro-continent (or exotic sialic terrain) formed by Archean rock units (the Crixas -Goias granitegreenstones) and associated Proterozoic formations (Almeida et al. 1981, Fuck et al. 1993,1994, Pimentel et al. 2000a, b). The sialic basement on which the Brasilia Belt sediments were deposited is poorly understood, despite being well exposed in some areas of Goias and Tocantins. Gneiss and volcano-sedimentary units form most of this basement. Early studies have suggested that these rock units are dominantly Archean ( Danni et al. 1982, Marini et al. 1984). However, recent Sm- Nd isotopic studies have indicated that most of them are Paleoproterozoic (Sato 1998, Pimentel et al. 1999a, 2000b). Granite gneiss to the south and east of the Barro Alto mafic-ultramafic layered complex has been dated at 2128+/- 15 Ma (Correia et al. 1997). Calc-alkaline granite gneiss from Almas-Dianopolis is dated at ca. 2.2-2.45 Ga old (U-Pb SHRIMP on zircon and titanite, Cruz et al. 2000). The latter is probably the western extension of Paleoproterozoic rocks which underlie the San Francisco Craton to the east of the northern part of the Brasilia Belt. In central Goias, a large part of the Brasilia Belt is underlain by high-grade metamorphic rocks known as the Anapolis-Itaucu Complex, together with surrounding greenschist to amphibolite facies Mesoto Neoproterozoic cover metasediments of the Araxa group. These rocks represent the main constituent of the internal zone of the Brasilia Belt (Fuck et al. 1994, Pimentel et al. 2000b). Between the Araxa Group, and the easternmost part of the Anapolis-Itaucu Complex a volcano-sedimentary association known as Silvania

    The irreversibility properties of high-T{sub c} superconductors are of major importance for technological applications. For example, a high irreversibility magnetic field is a more desirable quality for a superconductor . The irreversibility line in the H-T plane is constituted by experimental points, which divides the irreversible and reversible behavior of the magnetization. The irreversibility lines for series of La{sub 1.5+x}Ba{sub 1.5+x-y}Ca{sub y}Cu{sub 3}O{sub z} polycrystalline samples with different doping were investigated. The samples were synthesized using the usual solid estate reaction method. Rietveld-type refinement of x-ray diffraction patterns permitted to determine the crystallization of material in a tetragonal structure. Curves of magnetization ZFC-FC for the system La{sub 1.5+x}Ba{sub 1.5+x-y}Ca{sub y}Cu{sub 3}O{sub z}, were measured in magnetic fields of the 10-20,000 Oe, and allowed to obtain the values for the irreversibility and critical temperatures. The data of irreversibility temperature allowed demarcating the irreversibility line, T{sub irr}(H). Two main lines are used for the interpretation of the irreversibility line: one of those which suppose that the vortexes are activated thermally and the other proposes that associated to T{sub irr} a phase transition occurs. The irreversibility line is described by a power law. The obtained results allow concluding that in the system La{sub 1.5+x}Ba{sub 1.5+x-y}Ca{sub y}Cu{sub 3}O{sub z} a characteristic bend of the Almeida-Thouless (AT) tendency is dominant for low fields and a bend Gabay-Toulouse (GT) behavior for high magnetic fields. This feature of the irreversibility line has been reported as a characteristic of granular superconductors and it corroborates the topological effects of vortexes mentioned by several authors .

    Portugal has established itself as an independent state on October, 5th 1143 being confined to the south-eastern tip of Europe, with sealed land access to the rest of the continent by the others Iberian Peninsula kingdoms, enemies at the time who did not accept Portuguese autonomy. From the fourteenth century, the history of Portugal reports a period of epic discoveries. New commercial maritime routes have been established. Those routes sailing around Africa, passing through India, drove Portuguese people to Macao and Timor. To the East other routes reach the South American continent. Besides commercial interest, and because the church also financed these trips, they had the mission to evangelize the native peoples that were found. In every formed captaincies, over 29 actual countries, numerous churches, hospitals and fortifications were built. Combining a long tradition and mastery of monumental stone building and stonemasonry, which dates back to the Roman Period, Portuguese were able to combine the need to provide ships stability, using already worked stone as ballast. When arrived to these remote locations, quickly and with few local resources, could erect towering and admirable structures that still prevail today. Most of these regions were colonized and gave rise to independent countries in the 70's of the 20th Century, in some of them Portuguese is the official language and these constitutes the Community of Portuguese Language Countries (CPLP). This work shows that in addition to the language, traditions, customs, and architecture, there's also a very rich Portuguese Natural Stones monumental heritage building record, which constitutes a very strong link that binds this so special community.

Twelve weeks of plyometric training improves motor performance of 7- to 9-year-old boys who were overweight/obese: a randomized controlled intervention. J Strength Cond Res 31(8): 2091-2099, 2017-The prevalence of childhood overweight/obesity has increased, and physical training at school may to be effective to combat this scenario. We analyzed the effects of a protocol of plyometric training on body composition and motor performance of boys who were overweight/obese aged 7-9 years. The sample was randomly assigned into 2 groups: plyometric training group (T, n = 40) and control group (C, n = 19). Training consisted of 20 min·d (twice a week, during 12 weeks) of lower extremity plyometric exercise. Health-related physical fitness was measured by handgrip strength, standing long jump (SLJ), curl-ups, sit and reach, square test, running speed, and mile run test. Gross motor coordination was evaluated by means of the Körperkoordinations-test für Kinder (KTK) tests. Baseline and postintervention differences were investigated, and effect size was estimated through Cohen's d coefficient. Both groups showed increased body weight, height, and sitting height after intervention with a negligible effect size. Only T group showed increased fat-free mass (p = 0.011) compared with baseline values with small effect size. Plyometric training improved handgrip strength (d = 0.23), sit and reach (d = 0.18), curl-ups (d = 0.39), SLJ (d = 0.80), agility (d = 0.48), and time in the mile run test (d = 0.38). For gross motor coordination results, T group showed better performance in all tests after plyometric training with moderate/large effect size. Thus, 12 weeks of PT improved health-related physical fitness components and motor coordination acquisition of 7- to 9-year

A trajetória da pesquisa se deu por meio da abordagem qualitativa e seu desenrolar através de entrevistas semi-estruturadas com nove professoras de diferentes turmas da Educação Infantil. De acordo com os estudos e análises, entende-se que a relação professor-aluno deve possibilitar trocas de experiências e saberes entre ambos e que a afetividade é imprescindível na construção integral da criança, inclusive na formação de sua personalidade. É necessário também o professor se atentar para sua prática, seu planejamento e ser conhecedor de que suas ações interferem diretamente na história da criança, seja positiva ou negativamente. Conclui-se que o afeto do professor em sala de aula, principalmente na Educação Infantil, faz com que a aprendizagem seja muito mais significativa e os valores estejam em constante construção.Palavras-chave: educação; relação professor-aluno; afetividade; desenvolvimento infantil e ensino aprendizagem.

  8. Flat-ramp vs. convex-concave thrust geometries in a deformable hanging wall: new insights from analogue modeling experiments

    Different modes of strain accommodation affecting a deformable hanging-wall in a flat-ramp-flat thrust system were previously addressed through several (sandbox) analog modeling studies, focusing on the influence of different variables, such as: a) thrust ramp dip angle and friction (Bonini et al, 2000); b) prescribed thickness of the hanging-wall (Koy and Maillot, 2007); and c) sin-thrust erosion (compensating for topographic thrust edification, e.g. Persson and Sokoutis, 2002). In the present work we reproduce the same experimental procedure to investigate the influence of two different parameters on hanging-wall deformation: 1) the geometry of the thrusting surface; and 2) the absence of a velocity discontinuity (VD) that is always present in previous similar analogue modeling studies. Considering the first variable we use two end member ramp geometries, flat-ramp-flat and convex-concave, to understand the control exerted by the abrupt ramp edges in the hanging-wall stress-strain distribution, comparing the obtain results with the situation in which such edge singularities are absent (convex-concave thrust ramp). Considering the second investigated parameter, our motivation was the recognition that the VD found in the different analogue modeling settings simply does not exist in nature, despite the fact that it has a major influence on strain accommodation in the deformable hanging-wall. We thus eliminate such apparatus artifact from our models and compare the obtained results with the previous ones. Our preliminary results suggest that both investigated variables play a non-negligible role on the structural style characterizing the hanging-wall deformation of convergent tectonic settings were such thrust-ramp systems were recognized.

Recent studies have pointed out their effect on weight gain and increased visceral adiposity as they induce metabolic syndrome. Patients receiving SGAs often need to be treated with other substances to counteract metabolic side effects. In this paper, we point out the possible protective effect of add-on melatonin treatment in preventing, mitigating, or even reversing SGAs metabolic effects, improving quality of life and providing safer long-term treatments in pediatric patients. Melatonin is an endogenous indolamine secreted during darkness by the pineal gland; it plays a key role in regulating the circadian rhythm, generated by the suprachiasmatic nuclei (SCN of the hypothalamus, and has many other biological functions, including chronobiotic, antioxidant and neuroprotective properties, anti-inflammatory and free radical scavenging effects, and diminishing oxidative injury and fat distribution. It has been hypothesized that SGAs cause adverse metabolic effects that may be restored by nightly administration of melatonin because of its influence on autonomic and hormonal outputs. Interestingly, atypical anti-psychotics (AAPs can cause

    The cogeneration, or the combined production of electric and/or mechanical and thermal energy, is a well-established technology now, which has important environmental benefits and has been noted by the European Community as one of the first elements to save primary energy, to avoid network losses and to reduce the greenhouse gas emissions. In particular, our interest will be focused on the micro-cogeneration, MCHP (electric power up to 15 kW), which represents a valid and interesting application of this technology which refers, above all, to residential and light commercial users [M. Dentice d'Accadia, M. Sasso, S. Sibilio, Cogeneration for energy saving in household applications, in: P. Bertoldi, A.

In particular, our work group started a R and D programme on micro-cogeneration in 1995: a laboratory, equipped with the most common appliances (washing-machine, dishwasher, storage water heater, ...), has been built and some MCHP prototypes have been tested too. In this article, the results of an intense experimental activity on three different micro-cogenerators, one of them made in Japan and in a pre-selling phase, are reported. In a previous paper a detailed analysis of the test facility, with the description of the equipment and the data acquisition systems, can be found [M. Dentice d'Accadia, M. Sasso, S. Sibilio, R.

Direct medical cost estimates were determined by the price of drugs in 2008 and the hospital costs. Pain was evaluated using the Numerical Rating Scale (NRS and number of pain crises; the Hospital Anxiety and Depression Scale, Sickness Impact Profile, and satisfaction with treatment and hospital team were evaluated. Assessments were performed at day 0 and 6 months after the beginning of treatment. All protocols showed a clinical improvement of pain control at month 6. The GBP+ROP protocol was the least expensive treatment, whereas surgery was the most expensive. With time, however, GBP+ROP tended to be the most and MVD the least expensive.

    For disordered Heisenberg systems with small single ion anisotropy (D ), two spin-glass (SG) transitions below the long-range ordered (LRO) phase transition temperature (Tc) have been predicted theoretically for compositions close to the percolation threshold. Experimental verification of these predictions is still controversial for conventional spin glasses. We show that multiferroic spin-glass systems can provide a unique platform for verifying these theoretical predictions via a study of change in magnetoelastic and magnetoelectric couplings, obtained from an analysis of diffraction data, at the spin-glass transition temperatures (TSG). Results of macroscopic (dc M (H , T ), M(t ), ac susceptibility [χ (ω, T )], and specific heat (Cp)) and microscopic (x-ray and neutron scattering) measurements are presented on disordered BiFe O3 , a canonical Heisenberg system with small single ion anisotropy, which reveal appearance of two spin-glass phases, SG1 and SG2, in coexistence with the LRO phase below the Almeida-Thouless (A-T) and Gabey-Toulouse (G-T) lines. It is shown that the temperature dependence of the integrated intensity of the antiferromagnetic (AFM) peak shows dips with respect to the Brillouin function behavior around the SG1 and SG2 transition temperatures. The temperature dependence of the unit cell volume departs from the Debye-Grüneisen behavior below the SG1 transition and the magnitude of departure increases significantly with decreasing temperature up to the electromagnon driven transition temperature below which a small change of slope occurs followed by another similar change of slope at the SG2 transition temperature. The ferroelectric polarization also changes significantly at the two spin-glass transition temperatures. These results, obtained using microscopic techniques, clearly demonstrate that the SG1 and SG2 transitions occur on the same magnetic sublattice and are intrinsic to the system. We also construct a phase diagram showing all

    High frequency observations of the stable isotopic composition of CO(2) effluxes from soil have been sparse due in part to measurement challenges. We have developed an open-system method that utilizes a flow-through chamber coupled to a tunable diode laser (TDL) to quantify the rate of soil CO(2) efflux and its delta(13)C and delta(18)O values (delta(13)C(R) and delta(18)O(R), respectively). We tested the method first in the laboratory using an artificial soil test column and then in a semi-arid woodland. We found that the CO(2) efflux rates of 1.2 to 7.3 micromol m(-2) s(-1) measured by the chamber-TDL system were similar to measurements made using the chamber and an infrared gas analyzer (IRGA) (R(2) = 0.99) and compared well with efflux rates generated from the soil test column (R(2) = 0.94). Measured delta(13)C and delta(18)O values of CO(2) efflux using the chamber-TDL system at 2 min intervals were not significantly different from source air values across all efflux rates after accounting for diffusive enrichment. Field measurements during drought demonstrated a strong dependency of CO(2) efflux and isotopic composition on soil water content. Addition of water to the soil beneath the chamber resulted in average changes of +6.9 micromol m(-2) s(-1), -5.0 per thousand, and -55.0 per thousand for soil CO(2) efflux, delta(13)C(R) and delta(18)O(R), respectively. All three variables initiated responses within 2 min of water addition, with peak responses observed within 10 min for isotopes and 20 min for efflux. The observed delta(18)O(R) was more enriched than predicted from temperature-dependent H(2)O-CO(2) equilibration theory, similar to other recent observations of delta(18)O(R) from dry soils (Wingate L, Seibt U, Maseyk K, Ogee J, Almeida P, Yakir D, Pereira JS, Mencuccini M. Global Change Biol. 2008; 14: 2178). The soil chamber coupled with the TDL was found to be an effective method for capturing soil CO(2) efflux and its stable isotope composition at high

Methods: Sixty-nine biopsies were collected for immunohistochemical analysis for the presence of IL-6, IL-8, TNF-α, IFN-γ, TGF-β, and IL-10, in 16 fragments from atheromatous plaques, 32 aorta fragments, and 21 valve fragments, using a tissue microarray technique for paraffin embedded tissues. Results: Most patients undergoing revascularization surgery were men >50 years, while those undergoing valve replacement were mostly women <50 years. TNF-α was the most prevalent marker, detected in 91.7% (55/60 of the samples. The mean percent area stained was greater in patients infected with C. pneumoniae (3.81% vs 1.92%; p=0.0115 and specifically in the aorta (4.83% vs 2.25%; p=0.0025; C. trachomatis infection was higher in valves, and C. pneumoniae in plaques, both without statistical significance. There was no significant difference in the cytokine staining profile between patients previously infected with both species and uninfected patients. Conclusion: Although there was no difference in the cytokine profile between patients previously

In vivo, thirty goats that were naturally infected with GINs were divided into three groups: group I, treated with a daily dose of AE C. ambrosioides (700mg/kg for eight days; group II (positive control, treated with a single dose of levamisole phosphate (6.3mg/kg; and Group III, untreated (negative control. Treatment efficacy was assessed on the basis of egg counts (FEC, faecal cultures and post-mortem worm burden counts. Clinical and laboratory evaluations were performed to detect toxic effects associated with treatment. In the EHA, the EC50 and EC90 corresponded to 1.6 and 1.9mg/mL, respectively. The AE promoted a slight reduction in cell viability in the cytotoxicity test. The AE reduced (p <0.05 the number of infective larvae of the genera Haemonchus and Oesophagostomum. The anthelmintic treatment of goats with AE C.ambrosioides resulted in moderate efficacy against infective larvae, but revealed neither ovicidal nor toxic activity towards adult nematodes. No toxic

    Atualmente vivencia-se um mundo globalizado onde os computadores e a internet permitiram um acesso rápido e seguro a todo tipo de informação e conhecimento. O presente trabalho visa analisar a maneira pela qual alunos de segundo grau da rede estadual da cidade de São Paulo obtiveram, caso tenham, conhecimentos básicos de astronomia quanto aos fenômenos celestes que os rodeiam, tais como a sucessão dos dias e das estações do ano, além de questioná~los sobre fatos genéricos tais como: o que vem a ser o Sol, o Big Bang, o que ocasionou a extinção dos dinossauros. Para tanto foi elaborado um formulário constando de questões de múltipla escolha, o qual foi aplicado no primeiro colegial diurno da Escola Estadual Guilherme de Almeida. Num espaço amostral de 44 alunos constatou-se que 41% dos alunos adquiriram seus conhecimentos astronômicos na escola e 59% através da mídia em geral. Neste mesmo espaço amostral apenas 11% dos alunos usaram computadores na escola, 41% na residência, 5% no trabalho e 43% não utilizaram. O presente estudo revelou também que para 50% dos alunos o professor jamais utilizou um programa de computador a respeito de astronomia ou fez alguma apresentação sobre o tema. Embora em sua fase inicial este estudo revela claramente que a maioria dos alunos não obtém na escola seus conhecimentos astronômicos, estes provém de fontes não especificamente didático-pedagógicas tais como filmes e revistas populares que não raramente geram conhecimentos incompletos e em muitos casos inclusive falhos.

E-mail: vetjulio@yahoo.com.br Periodontal disease is the highest occurrence condition in the pet clinic, affecting mainly older animals because of its characteristic of chronicity. Among the clinical signs observed in afflicted animals, gingivitis is the first to be observed. The goal of this study was to develop a mucoadhesive gel, containing doxycycline and meloxicam, and evaluate its efficacy as an adjuvant in the treatment of gingivitis induced by periodontal disease, with a clinical and histopathological rating. Eighteen Beagle dogs presenting gingivitis secondary to periodontal disease were divided into three experimental groups. Group I – animals treated with placebo formulation. Group II – Animals treated with a chitosan gel formulation containing doxycycline. Group III - Animals treated with a chitosan gel formulation containing doxycycline and meloxicam. All animals were treated for seven days, every twelve hours, in the gingival margin of the right maxilla. During the clinic evaluation, only the animals treated with the product containing doxycycline had improved. Contrasting, in the histopathologic evaluation, only animals treated with association of doxycycline and meloxicam presented improvements in their clinical score, although no

    Bernardes, WL, Montenegro, RA, Monteiro, WD, de Almeida Freire, R, Massaferri, R, and Farinatti, P. Optimizing a treadmill ramp protocol to evaluate aerobic capacity of hemiparetic poststroke patients. J Strength Cond Res 32(3): 876-884, 2018-A correct assessment of cardiopulmonary capacity is important for aerobic training within motor rehabilitation of poststroke hemiparetic patients (PSHPs). However, specific cardiopulmonary exercise testing (CPET) for these patients are scarce. We proposed adaptations in a protocol originally developed for PSHPs by Ovando et al. (CPET1). We hypothesized that our adapted protocol (CPET2) would improve the original test, by preventing early fatigue and increasing patients' peak performance. Eleven PSHPs (52 ± 14 years, 10 men) performed both protocols. CPET2 integrated changes in final speed (100-120% vs. 140% maximal speed in 10-m walking test), treadmill inclination (final inclination of 5 vs. 10%), and estimated test duration (10 vs. 8 minutes) to smooth the rate of workload increment of CPET1. Peak oxygen uptake (V[Combining Dot Above]O2peak) (20.3 ± 6.1 vs. 18.6 ± 5.0 ml·kg·min; p = 0.04), V[Combining Dot Above]O2 at gas exchange transition (V[Combining Dot Above]O2-GET) (11.5 ± 2.9 vs. 9.8 ± 2.0 ml·kg·min; p = 0.04), and time to exhaustion (10 ± 3 vs. 6 ± 2 minutes; p higher in CPET2 than in CPET1. Slopes and intercepts of regressions describing relationships between V[Combining Dot Above]O2 vs. workload, heart rate vs. workload, and V[Combining Dot Above]O2 vs. heart rate were similar between CPETs. However, standard errors of estimates obtained for regressions between heart rate vs. workload (3.0 ± 1.3 vs. 3.8 ± 1.0 b·min; p = 0.004) and V[Combining Dot Above]O2 vs. heart rate (6.0 ± 2.1 vs. 4.8 ± 2.4 ml·kg·min; p = 0.05) were lower in CPET2 than in CPET1. In conclusion, the present adaptations in Ovando's CPET protocol increased exercise tolerance of PSHPs, eliciting higher V[Combining Dot Above]O2peak

Therefore, there is a great need for alternative methods to control infections, especially those related to skin. One of the alternative methods is the high frequency equipment (HFE, which is used on skin conditions as an analgesic, an anti-inflammatory, and mainly to accelerate cicatricial processes and have a bactericidal effect through the formation of ozone. This research investigated the antibacterial effect of HFE on standard cultures of bacteria.Materials and methods: Dilutions (104 colony forming unit mL−1 were performed for Enterobacter aerogenes and Staphylococcus aureus with 24-hour growth bacteria. Then, 1 μL of each dilution was pipetted into suitable medium and the HFE flashing technique was used at intensities of 6, 8 and 10 mA for 30, 60, 90, 120 and 180 seconds. The control group received no treatment. Plates were incubated at 37°C for 24 hours and then read.Results: The spark at intensity of 6 mA had no bactericidal effect on the E. aerogenes; however, a significant bacterial growth reduction occurred at intensity of 8 mA after 120 and 180 seconds, and at 10 mA, reduction in bacterial growth could already be verified at 30 seconds and total bacterial growth inhibition occurred in 180 seconds. For S. aureus, there was a strong bacterial growth inhibition at all intensities used; however, at 6 mA, absence of bacterium growth after

    Full Text Available Jaboticatubas is a municipality in the metropolitan region of Belo Horizonte which has been a target of a wide media release as "the capital of schistosomiasis" since the 1960's. In order to give support to a work based on an integrated control, we sought to identify the disease determinants at the site. A transversal study was carried out aimed at identifying prevalence rates of the disease and factors associated with the infection in the district of São José de Almeida, and two close localities, Cipó Velho and São José da Serra, all of them located in the municipality of Jaboticatubas. A parasitological survey was performed, applying the Kato-Katz method with two slides per sample in 1186 schoolchildren which represents 77% of all registered pupils in four public schools in 2001. Among these schoolchildren a number of 101 (8.6% prooved positive for Schistosoma mansoni eggs in their stool samples. A total of 64 families, whose schoolchildren had shown to be positive for schistosomiasis, also undertook examinations. As negative control, a random sample was collected from the 206 families, whose children had proven negative for schistosomiasis. The prevalence among 270 families (1304 people was 12%. To assess those who continued to have contact with possibly contaminated water, 1061 (81.4% people of the 270 families were interviewed. A multivariate analysis identified the following factors associated with the infection: time of residence in the area (short period, garbage disposal (use of deserted areas, gender (male, age (from 10 to 29 years, and water contact (daily and weekly. Further analysis of these factors revealed a close correlation between water contact and the disease, with a positive significant frequency concerning almost all those items. Depending on gender and age significant variations of water contact patterns associated with leisure and professional activities were found. A malacological survey on water collections in the

Daptomycin was encapsulated into PCL microparticles by a double emulsion-solvent evaporation method. For comparison purposes, formulations containing vancomycin were also prepared. Particle morphology, size distribution, encapsulation efficiency, surface charge, thermal behavior, and in vitro release were assessed. All formulations exhibited a spherical morphology, micro­meter size, and negative surface charge. From a very early time stage, the released concentrations of daptomycin and vancomycin were higher than the minimal inhibitory concentration and continued so up to 72 hours. Daptomycin presented a sustained release profile with increasing concentrations of the drug being released up to 72 hours, whereas the release of vancomycin stabilized at 24 hours. The antibacterial activity of the microparticles was assessed by isothermal microcalorimetry against planktonic and sessile MRSA and S. epidermidis. Regarding planktonic bacteria, daptomycin-loaded PCL microparticles presented the highest antibacterial activity against both strains. Isothermal

E-mail: elmiro@vm.uff.br Avian infectious bronchitis (IB is a viral, acute and highly contagious disease caused by infectious bronchitis virus (IBV. The disease affects broilers improvement and performance causing major economic losses in the world poultry industry. Generally, IBV infections can be diagnosed by detection of IBV itself or the specific antibody response. This study aimed to detect IBV in broilers under Sanitary Inspection by RT-PCR and ELISA, comparing the results and relating them with the average weight of the flock. Samples were collected from 40 vaccinated broiler flocks under Sanitary Inspection at slaughter. Ten birds from every flock were randomly selected and blood samples were collected for ELISA as well three birds had their trachea and caecal tonsils collected for RT- -PCR test. From 40 flocks, 30 were IBV positive by ELISA and 26 by RT-PCR, in which 15 were detected simultaneously in trachea and caecal tonsil and 5 in each sample. There was no agreement between ELISA and RT-PCR results regarding IBV diagnosis as well positivity in both tests was not statistically significant with the average weight of the flock. There was an improvement on IBV diagnosis when caecal tonsils and tracheas were used instead of just one of them. Considering the only vaccine serotype allowed by Brazilian government is the Mass serotype and its persistence in broilers would only be detected up to 28 days

Ten highly trained Olympic boxing athletes (six men and four women performed a maximal graded exercise test on a motorized treadmill to determine maximal oxygen uptake (52.2 mL · kg-1 · min-1 ± 7.2 mL · kg-1 · min-1 and ventilatory thresholds 1 and 2. Ventilatory thresholds 1 and 2 were used to classify the intensity of exercise based on respective HR during a boxing match. In addition, oxygen uptake (VO2 was estimated during the match based on the HR response and the HR-VO2 relationship obtained from a maximal graded exercise test for each participant. On a separate day, participants performed a boxing match lasting three rounds, 2 minutes each, with a 1-minute recovery period between each round, during which HR was measured. In this context, HR and VO2 were above ventilatory threshold 2 during 219.8 seconds ± 67.4 seconds. There was an increase in HR and VO2 as a function of round (round 3 < round 2 < round 1, P < 0.0001.These findings may direct individual training programs for boxing practitioners and other athletes.

    Full Text Available O artigo propõe a inclusão de canções da música popular brasileira em disciplinas que se voltam para o estudo da Língua e da Literatura, como estratégia para aproximar os jovens da poesia. Canções, por sua forma de circulação, invadem o mundo dos jovens e a eles apresentam características formais da poesia lírica, além de traduzir emoções e sentimentos coletivos. Sob tal ângulo, canção e poesia não se distinguem por seus componentes estruturais, visto que ambas as modalidades podem ser dotadas de atributos estéticos. Esse ponto de vista é respaldado, no artigo, pelo posicionamento de estudiosos como Marisa Lajolo, Salete de Almeida Cara, Salvatore D’Onofrio e pela exposição da origem da poesia e de sua evolução, as quais comprovam que traços sonoros estão presentes em poemas contemporâneos, ainda que o registro da palavra escrita tenha provocado a ruptura entre a arte poética e a música. Para comprovar a legitimidade da convergência de poemas e de canções, os autores do artigo analisam e interpretam textos pertencentes a ambos os gêneros, neles evidenciando elementos em comum, como a exploração dos recursos expressivos da linguagem, que invocam a participação do receptor no deciframento de suas significações, e reflexões sobre a condição humana e sobre suas circunstâncias. Portanto, os autores afirmam que razões de ordem estética e sociocultural justificam a inclusão de canções no âmbito escolar, uma vez que, assim como poemas, elas concretizam a finalidade da arte de conferir palavras aos sentimentos humanos, enquanto reafirmam o potencial expressivo da linguagem lírica.

Both groups performed a periodized RT program consisting of two weekly sessions for 16 weeks. All measures were assessed at baseline and postintervention, including anthropometry and body composition (dual-energy X-ray absorptiometry, muscle strength (one repetition maximum for chest press and 45° leg press, and functional capacity (stand up, elbow flexion, timed “up and go”.Results: After the intervention, only the non-SO group presented significant reductions in percentage body fat (-2.2%; P=0.006, waist circumference (-2.7%; P=0.01, waist-to-hip ratio (-2.3; P=0.02, and neck circumference (-1.8%; P=0.03 as compared with baseline.

  17. Placement of Public Art. Two Examples from Lisbon’s Waterfront

    In our contemporary cities, some public spaces seem to have greater ability to host art interventions, like historical centers, urban sprawl areas, gardens and parks, new residential districts, among others. Also in port cities, its waterfronts constitute privileged spaces for the placement of public art. On Lisbon’s riverfront, we can see a relevant number of works and of monuments of strong symbolic nature. In turn, the placement of public art is a way to value the inherently symbolic nature of the waterfronts and to emphasize its monumentality. However, the criteria for the placement of public art on those spaces are not always clear. In some cases, there are some thematic correspondences between the works and the places, namely with the theme of the water, the Discoveries and others like that. Nevertheless, we cannot observe a profound spatial integration, or a design with the context. In some cases, the artistic elements are produced with a logic of isolated work of art and later they are acquired and placed in some public space. In other cases, we assist to an unusual situation: a work is conceived in a strict relation with a place, but then, without any evident justification, it is dislocated to a completely different context. Or simply it is removed, disappearing from the public space. Although it seems a strange situation, such kind of dislocations often occurs in Lisbon. On this framework, this research proposes a discussion about the processes of implementation of public art. We will analyze two cases of public art replacement:1) The monument Primeira Travessia Aérea do Atlântico Sul (First Aerial Crossing of the South Atlantic), by Laranjeira Santos and Rodrigues Fernandes, 1972; and 2) The public sculpture Ribeira das Naus, by Charters de Almeida, 1995. Both works were designed to very specific and important places on Lisbon’s waterfront and both were later replaced to other locations on the inner city, quite far from the river. This kind of

The blood samples the Gprpme group that was done PRP, the mean platelet count after centrifugation was 1,288,750 platelets/uL. The results obtained in the PRP final sample when compared to the inicial were significantly greater. Thus, the double centrifugation protocol for obtaining PRP which was performed in this trial was appropriate, because the platelet concentration after double centrifugation increased three times as compared with the initial count of the blood sample, and it was possible to achieve good therapeutic results.

    Full Text Available Atualmente, estamos vivendo em dias, onde os conceitos são mais importantes que as atitudes, ou o bem estar de nossos educandos. A sede por números positivos nas avaliações do MEC, por muitas vezes impossibilitam que o desenvolvimento de nossos alunos seja equilibrado. O professor é o profissional que está em contato diário com estes sujeitos aprendentes, logo é ele que observará as dificuldades apresentadas pelos mesmos. Perdurou-se por tempos, o rótulo de que os alunos que apresentavam alguma dificuldade de aprendizagem eram desprovidos de inteligência, sendo classificados até como “burros”, entretanto, atualmente podemos ver que este campo da educação, tem ganhado uma atenção especial. O presente artigo tem como propósito apresentar algumas considerações acerca da atuação do professor diante a disgrafia, tendo como objetivo geral compreender como o educador deve posicionar-se ao encontrar em sala de aula um aluno com sinais de disgrafia, objetivando a melhora da aprendizagem deste educando. A metodologia utilizada na pesquisa é de caráter bibliográfico, onde recorremos a autores como Topczewski (2011, Almeida (2010, Fonseca (1995, Vallet (1977, entre outros. Elucidamos a importância da formação continuada, visto que as dificuldades de aprendizagem não são estudadas na graduação, e os educadores precisam estar preparados para lidarem com alunos que possuam disgrafia em sala de aula, na tentativa de evitar rótulos enganosos e desempenhos insatisfatórios. Enfim, compreendemos que a função do professor diante da disgrafia é ser um facilitador e um motivador, e também deve mostrar a este educando as suas habilidades e competências. Espera-se, então que o professor desperte-se, e promova mudanças em sua sala de aula, visando alcançar estes alunos que convivem com esta limitação em seu dia-a-dia. Em conformidade com o que foi apresentado nesta pesquisa, o aluno com disgrafia apresenta suas

    Full Text Available As bases técnicas para o controle da doença de Chagas no Brasil foram estabelecidas com a criação do posto avançado de pesquisa do Instituto Oswaldo Cruz em Bambuí, no oeste de Minas Gerais, no começo da década de 40, sob a liderança de Emmanuel Dias. Entretanto, somente com a criação do Departamento Nacional de Endemias Rurais (DNERu, em março de 1956, sob a direção de Mario Pinotti, no governo de Juscelino Kubitschek, as medidas de controle foram implementadas. Das "campanhas" de controle das 12 endemias rurais estabelecidas pelo DNERu, a malária, pelo seu caráter de doença aguda e explosiva, sempre teve a maior parte orçamentária. A doença de Chagas e as outras endemias foram sempre relegadas a um plano secundário de prioridade. Por outro lado, a partir da década de 60, os "novos ecologistas" passaram a criticar o uso de inseticidas, com o slogan de que para controlar a doença de Chagas era necessário o BNH (construção de casas, e não o BHC (uso de inseticidas. Esta opinião, embora equivocada para o controle a curto prazo, teve uma enorme influência negativa sobre o controle dos vetores domiciliados. Apesar disso, algum progresso foi feito neste sentido. Na década de 70, a epidemia de meningite meningocócica e a priorização do Programa Especial de Controle da Esquistossomose (PECE, pelo Ministro Almeida Machado, com deslocamento de verbas e de pessoal da Superintendência de Campanhas (Sucam para esses programas, atrasaram ainda mais o controle da doença de Chagas. Somente na década de 80, com a decisão política do Banco Nacional de Desenvolvimento Econômico e Social (BNDES de alocar 10 bilhões de cruzeiros do Finsocial, o programa de controle da doença de Chagas teve um importante desenvolvimento em 2.000 municípios de 19 Estados brasileiros. Mais uma vez o programa sofre um atraso nesta década, com o deslocamento do pessoal da Sucam para a campanha contra a epidemia da dangue. Finalmente, conclu

Was conducted a study of 16 rabbits, New Zealand white, female, 60 days old. They were divided into two groups with eight animals each, all of which was undergoing reconstructive surgery technique for making mesh graft. The groups were constituted in Gprpme received PRP gel and Gcme who received 0.9% saline solution combining both surgical sponge as a way of curative. The blood samples the Gprpme group that was done PRP, the mean platelet count after centrifugation was 1,288,750 platelets/uL. The results obtained in the PRP final sample when compared to the inicial were significantly greater. Thus, the double centrifugation protocol for obtaining PRP which was performed in this trial was appropriate, because the platelet concentration after double centrifugation increased three times as compared with the initial count of the blood sample, and it was possible to achieve good therapeutic results. In the macroscopic evaluation of the 3rd day, exudate showed significant differences in Gprpme compared to Gcme. In the evaluations of the 7th and the

    Em sua nova edição, a primeira de 2007, a Ciberlegenda traz oito artigos de docentes e discentes de Comunicação e afins. As áreas temáticas contempladas por esses trabalhos acompanham, em alguma medida, as linhas de pesquisa desenvolvidas no PPGCOM/UFF, a saber: comunicação e mediação; tecnologias da comunicação e da informação; análise da imagem e do som.


    Assim, os dois primeiros artigos, de autoria de Vera Follain de Figueiredo e Dinaldo Almendra, apresentam interessantes discussões sobre as imbricações entre os universos da literatura e o do cinema, buscando perceber, a partir dessa interação, múltiplos processos de deslocamentos e reapropriações.


    As relações entre tecnologia e modernidade, em uma diversidade de perspectivas, são o fio condutor dos artigos de Fernando Krüger e Dulce Cruz, Fabíola Calazans e Maria Clara Aquino. Os dois primeiros descrevem e analisam o game The Sims, relacionando-o com a geração Y, em uma reflexão sobre juventude contemporânea e consumo de tecnologia. Fabíola Calazans, em seu artigo, debate as experiências tecnológicas perceptivas na cultura moderna, a partir de autores como Raymond Williams e Walter Benjamin. E, por fim, Maria Clara Aquino passeia pelo mundo do hipertexto, focando o caso da Web 2.0 como objeto de sua análise.


    Encerrando essa edição, os três últimos trabalhos abordam, a partir de diversos ângulos, a questão da imagem. Ana Elisa Viviani investiga a relação entre corpo, arte, imagem e modernidade. Jorge Almeida e Santo Scaldaferri analisam campanhas publicitárias, enfocadas a partir do instrumental teórico do marketing político. E João Batista Cardoso, em co-autoria com Roberto dos Santos

    and its breaching such as depth, wide, length, volume and breaching shape and daily total rainfall data were used in the models. The simulated flooding in the both models were compared with the real flood extent which gathered from photos taken after the flood event, high satellite images acquired after 20 days from the flood event, and field works. The results show that LISFLOOD-Roe hydraulic model gives more than 80% fit to the extent of real flood event. Also both modelling results show that the embankment breaching of the Ata Pond directly affected the flood magnitude and intensity on the area. This study reveals that modelling of the probable flooding in urban areas is necessary and very important in urban planning. References Gallegos, H. A., Schubert, J. E., and Sanders, B.

    Full Text Available Introdução: Trata-se de uma revisão integrativa que tem como objetivos analisar as concepções de integralidade e de cuidado de saúde (e de enfermagem evidenciada nos artigos encontrados na Biblioteca Virtual em Saúde e conhecer a relação entre integralidade e o cuidado em saúde na Atenção Primária à Saúde, relatados entre os trabalhos encontrados na BVS. Materiais e Métodos: Foi feita a seleção dos artigos que tinham como principal assunto a Atenção Primária à Saúde, publicados e indexados no banco de dados National Library of Medicine e Literatura Latino-Americana e do Caribe em Ciências da Saúde. Totalizaram 09 artigos publicados no período de 2010 a 2012. A análise dos materiais se deu através da análise de conteúdo de Bardin. Resultados e Discussão: Mostrou-se a necessidade de que a enfermagem reconheça a integralidade como norteadora de suas práticas de saúde, valendo-se do trabalho vivo em saúde para a produção do cuidado. Ao mesmo tempo em que identifiquem em seu cotidiano as várias formas de efetuá-lo, garantindo assistência de qualidade, cuidado, corresponsabilização, vínculo e intersetorialidade, na medida em que se busca a longitudinalidade do cuidado em saúde. Conclusões: A partir dos estudos reconhece-se que a integralidade é vista como um ponto chave para a produção do cuidado, desde que sejam contempladas as necessidades reais dos indivíduos, em atividades cotidianas da Atenção Primária à Saúde, no que engloba a mudança de concepções entre o modelo biomédico, ainda predominante, para um olhar que tenha foco as várias dimensões dos indivíduos.Palavras chave: Assistência Integral à Saúde, Cuidados de Enfermagem, Prestação Integrada de Cuidados de Saúde.

The as-developed nanosized material device, consisting of surface decorated maghemite nanoparticles suspended as a biocompatible magnetic fluid (MF sample, labeled MF-anti-CEA, was characterized and tested against two cell lines: a high-CEA expressing cell line (LS174T and a low-CEA expressing cell line (HCT116. Whereas X-ray diffraction was used to assess the average core size of the as-synthesized maghemite particles (average 8.3 nm in diameter, dynamic light scattering and electrophoretic mobility measurements were used to obtain the average hydrodynamic diameter (550 nm and the zeta-potential (−38 mV of the as-prepared and maghemite-based nanosized device, respectively. Additionally, surface-enhanced Raman spectroscopy (SERS was used to track the surface decoration of the nanosized maghemite particles from the very first precoating up to the attachment of the anti-CEA moiety. The Raman peak at 1655 cm−1, absent in the free anti-CEA spectrum, is the signature of the anti-CEA binding onto the precoated magnetic nanoparticles. Whereas MTT assay was used to confirm the low cell toxicity of the MF-anti-CEA device, ELISA and Prussian blue iron staining tests performed with both cell lines (LS174T and HCT116 confirm that the as-prepared MF

Tasks or processors are distributed evenly by default, but uneven distributions are possible under programmer control. It is also possible to explicitly enable child tasks to migrate within the processor set owned by their parent task, reducing load unbalancing at the potential cost of increased inter-processor message traffic. PM incorporates some programming structures from the earlier MIST language presented at a previous EGU General Assembly, while adopting a significantly different underlying parallelisation model and type system.

The Nd-TDM (model ages referred to depleted mantle) of clinopyroxenes and host rocks record, to some extent, earlier fluid-infiltration events. These appear defined between 135 and 1065 Ma (Table 3), with more than 50% model ages spanning the Brasiliano cycle (i.e. 1000-450 Ma, cf. Almeida and Hasui, 1984). Considering that in the Asuncion-Sapucai- Villarrica area the magmatism (Early Cretaceous: tholeiitic and K-alkaline-carbonatitic rocks; Late Cretaceous to Tertiary: Na-alkaline rocks) demands that their parental magmas derived from an heterogeneous subcontinental mantle (garnet peridotite; Comin-Chiaramonti et al., 1997), significant fluids are expected to modify the isotope ratios of the overlaying spinel peridodites. On this respect, the younger Nd-TDM and the Rb-Sr systematics may reflect the main melting 3 episodes occurring in the mantle regions during the different phases of lithospheric thinning (cf. Comin- Chiaramonti and Gomes, 1996) and repeated interactions between fluids and overlaying peridotites (au)

    Abrimos nossa revista com dois artigos de pesquisadores franceses Philippe Savoie e Renaud d’Enfert que com seus textos Criação e reinvenção dos Liceus (1802-1902 e Uma nova forma de ensino de desenho na França no início do Século XIX: o desenho linear nos trazem preciosa contribuição à investigação da história da educação do século XIX. É sabido de todos os estudiosos da área de educação a contribuição da França para a constituição do sistema de ensino brasileiro, portanto estes trabalhos trazem novas luzes no sentido de melhor conhecermos a gênese do estrutura educacional do século XIX.

    Com o texto A co-educação dos sexos: apontamentos para uma interpretação histórica a renomada pesquisadora Jane Soares de Almeida nos brinda com um trabalho de excepcional qualidade e que contribui para uma melhor compreensão da questão da coeducação.

    O professor Dagoberto Buim Arena retoma uma questão relacionada aos movimentos anarquistas e que tem ocupado a atenção de vários estudiosos na área da História da Educação. Escolas anarco-sindicalistas no Brasil: alguns princípios, métodos e organização curricular é mais uma contribuição para a construção de um bom entendimento da atuação deste movimento ideológico na área da educação.

    No trabalho Puc-Campinas: as mudanças institucionais narradas por seus docentes mais velhos, os professores Rogério Canciam; Vera Lúcia de Carvalho Machado retomam com propriedade e competência uma questão teórico-metodológica muito investigada na área de História da

    Full Text Available As bases técnicas para o controle da doença de Chagas no Brasil foram estabelecidas com a criação do posto avançado de pesquisa do Instituto Oswaldo Cruz em Bambuí, no oeste de Minas Gerais, no começo da década de 40, sob a liderança de Emmanuel Dias. Entretanto, somente com a criação do Departamento Nacional de Endemias Rurais (DNERu, em março de 1956, sob a direção de Mario Pinotti, no governo de Juscelino Kubitschek, as medidas de controle foram implementadas. Das "campanhas" de controle das 12 endemias rurais estabelecidas pelo DNERu, a malária, pelo seu caráter de doença aguda e explosiva, sempre teve a maior parte orçamentária. A doença de Chagas e as outras endemias foram sempre relegadas a um plano secundário de prioridade. Por outro lado, a partir da década de 60, os "novos ecologistas" passaram a criticar o uso de inseticidas, com o slogan de que para controlar a doença de Chagas era necessário o BNH (construção de casas, e não o BHC (uso de inseticidas. Esta opinião, embora equivocada para o controle a curto prazo, teve uma enorme influência negativa sobre o controle dos vetores domiciliados. Apesar disso, algum progresso foi feito neste sentido. Na década de 70, a epidemia de meningite meningocócica e a priorização do Programa Especial de Controle da Esquistossomose (PECE, pelo Ministro Almeida Machado, com deslocamento de verbas e de pessoal da Superintendência de Campanhas (Sucam para esses programas, atrasaram ainda mais o controle da doença de Chagas. Somente na década de 80, com a decisão política do Banco Nacional de Desenvolvimento Econômico e Social (BNDES de alocar 10 bilhões de cruzeiros do Finsocial, o programa de controle da doença de Chagas teve um importante desenvolvimento em 2.000 municípios de 19 Estados brasileiros. Mais uma vez o programa sofre um atraso nesta década, com o deslocamento do pessoal da Sucam para a campanha contra a epidemia da dangue. Finalmente, conclu

    Su técnica original esquematizada con brocha gorda consistía en trepanación del craneo en la región frontal lateral de ambos lados, transfixión del hemisferio cerebral por medio de una cánula apropiada e inyecciones de alcohol absoluto que destruía la sustancia blanca, es decir, las fibras de asociación. Poco después el alcohol fue abandonado y reemplazado por corte quirúrgico por medio de un instrumento semejante a un corta papel de bordes romos que denominaron “leucótomo”, estableciendo así su técnica denominada “Lobotomía” que se expandió rápidamente por todo el mundo, técnica que fue perfeccionada por los norteamericanos Freeman y Watts de Washington D.C. denominándola “Lobotomía prefrontal bilateral”, y que practicó en Bogotá Camacho con algunas modificaciones personales, de 1941 en adelante, como consta en esta Reseña...

  12. Thirty-five years of geochronology in Uruguay

    The radiometric ages obtained abroad have been systematically integrated with the field geology over the last thirty five years. The difference between the radiometric ages and their geochronology interpretation was realized rather early in the investigations. The few opportunities for radiometric determinations of rocks and minerals required careful regional geological mapping, based on models which were predominant at the time. Untial 1965, the pre-Devonian rocks in Uruguay were divided into Archean and Algonkian. The Archean units included medium metamorphic grade rocks and all the plutonic rocks. The Algonkian units were the low metamorphic grade supracrustal belts. The tectono-stratigraphic proposal presented at the International Geological Congress in India (1960) induced the division into two orogenic cycles and the radiometric dating with the techniques available at the time: K-Ar already in use and Rb-Sr isochrons, which were considered accurate and precise. The work of Hart (1966) resulted in ten ages, grouped in two geographically separated age sets: 600-500 Ma in the southeast and ca. 2000 Ma in the south and southwest. Bossi et al. (1967) identified two orogenic cycles based on geological mapping at the 1:250,000 scale, no intermediate ages. These cycles were recognized until 1991, although some improvements occurred in limits of units and cartography and some changes in nomenclature and integration of the Rb-Sr isotopic data by Umpierre and Halpern (1971), Soliani Jr. (1986), Renne (1991, pers. comm.). The proposal of a Trans-Amazonian craton in the west (Ciclo Orogenico Antiguo) and a mobile belt in the east (Ciclo Orogenico Moderno) was accepted for 25 years. Many Brazilian (e.g., Fragoso Cesar, 1980) and some Uruguayan authors included the 'Ciclo Orogenico Moderno in the Brasiliano Cycle of Almeida (1976). The consistency of this proposal has been accepted up to today, because 800-550 Ma granitic rocks are intruded in low metamorphic grade

    Full Text Available Normal 0 21 false false false PT-BR X-NONE X-NONE Introdução: O Brasil é, ainda hoje, uma dos países mais desiguais da América Latina e, também, no mundo. Apesar disso, o relatório da ONU (PNUD, 2011, p. 42 destaca que o Brasil, tem logrado importantes avanços na redução das desigualdades. A redução da desigualdade tem como um dos seus resultados o fortalecimento do mercado interno. De acordo com as argumentações de Silveira (2002, 2004, 2007, 2008, 2009, 2010, apesar disso, o modo como as variáveis modernas atingem as regiões do país, pode ser encarado como uma nova forma de violência que se instaura sobre o território, através da drenagem da riqueza e do dinheiro social. Em muitas regiões chegou os bens mais modernos enquanto os direitos sociais mais básicos, como acesso ao saneamento básico e aos serviços de saúde, ainda é muito precário. O problema se torna ainda mais complexo quando consideramos que, em função das escolhas políticas feitas para as diversas políticas sociais, em especial as de saúde, ao longo do século XX (Almeida, 2005, os direitos sociais mais básicos se tornaram muito dependentes da dinâmica de mercado. Nesse contexto, nas regiões onde o mercado ainda não despertou interesse, o Estado é levado a ter uma função mais ativa para garantir a presença de variáveis que sustentam o acesso a direitos básicos. O caso dos serviços de alta complexidade é um exemplo emblemático dessa situação que se passa sobre o território nacional.

    two tectono-stratigraphic sets with the eastern portion occupied by parautochthonous units of a passive continental margin (Port Nolloth Zone) and a western allochthonous domain (Marmora Terrane). The evidences of blueschist facies metamorphism, countless times referred in the literature (Kröner, 1974; Porada, 1979), have been recently ruled out by Frimmel and Hartnady (1992). The sedimentation period of the Gariep Group is attributed to the Neoproterozoic because it lays discordantly on the rhyolite units (Ross Pinah Formation) dated by the single zircon evaporation technique as 735Ma (Frimmel, 1995). Meert §& Van der Voo (1994) correlated diamictite intercalations, probably of age between 580 and 560 Ma, in the upper portion of the Gariep Group with the glacial deposits of Vendian age. The northeastern portion of the Gariep Group is covered by not metamorphosed sediments of the Nama Group. In the South-American counterpart, that is, the South-Brazilian region and the Uruguayan territory, an old western domain is observed The Central Domain is represented by the Rio de La Plata Craton (sensus Almeida et al.,1973) ,by de Nico Perez Terrane (Bossi et al.,1992 ;Valentines Block,PavasTerrane (Preciozzi et al.,1979) and the Rivera granitic-gneissic complex ..All of them were generated or intensively reworked during the Neoproterozoic, distributed along its eastern border and as a whole organised in the NE-SW direction. In these domain, a granitic-migmatitic infrastructure and sedimentary basins and low- to medium metamorphic grade covers predominate, related to the Lavalleja-supergroup and Zanja del Cerro Grande Group The Rocha formation is developed as a metasedimentary cover in the Punta del Este Terrane,being associated to the Atlantic Domain. Geochronologic studies recently performed in the southeastern portion of Uruguay allowed the identification of igneous rocks with U-Pb ages in zircons ranging from 650 to 1000Ma. These ages, added to the geological

Foram utilizados dados das reanálises do National Center for Environmental Prediction e do experimento de assimilação de dados do Geophysical Fluid Dynamics Laboratory, bem como realizadas simulações da atmosfera em escala global, aplicando o Community Climate Model do National Center for Atmopheric Research e, simulações oceânicas em escala de bacia com o Princeton Ocean Model. Os resultados dos modelos mostraram alterações no padrão de circulação das células de Hadley e Walker, implicando no comportamento da Alta Subtropical do Atlântico. O Oceano respondeu com aumento do transporte da Corrente do Brasil e intensificação da corrente das Malvinas. A ACAS ficou mais rasa respondendo à variação do balanço de Sverdrup.

    Pitkanen and Peterson 2003) or the targeted inactivation (Anderson et al. 2002; Ramsey et al. 2002) of the AIRE transcription factor that regulates promiscuous gene expression on TECs support this conclusion. The observations on the correlation of natural or forced expression of the Foxp3 transcription factor in CD4 T cells with Treg phenotype and function (Fontenot et al. 2003; Hori et al. 2003; Khattri et al. 2003) provided support for the MM96 contention that Treg represent a unique differentiative pathway that is naturally established inside the thymus. Furthermore, Caton and colleagues (Jordan et al. 2001), as well as several other groups (Bensinger et al. 2001; Apostolou et al. 2002), have provided direct evidence for our postulate that Treg are selected among differentiating CD4 T cells with high affinity for ligands expressed on TECs (Modigliani et al. 1996b). Finally, the demonstration by Caramalho et al. that Treg express innate immunity receptors (Caramalho et al. 2003) and respond to pro-inflammatory signals and products of inflammation (Caramalho et al., submitted) brought about a new understanding on the peripheral regulation of Treg function. Together with the observation that Treg also respond to ongoing activities of "naïve/effector" T cells--possibly through the IL-2 produced in these conditions--these findings explain the participation of Treg in all immune responses (Onizuka et al. 1999; Shimizu et al. 1999; Annacker et al. 2001; Curotto de Lafaille et al. 2001; Almeida et al. 2002; Shevach 2002; Bach and Francois Bach 2003; Wood and Sakaguchi 2003; Mittrucker and Kaufmann 2004; Sakaguchi 2004), beyond their fundamental role in ensuring self-tolerance (e.g., Modigliani et al. 1996a; Shevach 2000; Hori et al. 2003; Sakaguchi 2004; Thompson and Powrie 2004). Thus, anti-inflammatory and anti-proliferative Treg are amplified by signals that promote or mediate inflammation and proliferation, accounting for the quality control of responses (Coutinho et al

    Os professores Maria Aparecida Muccilo e Newton César Balzan em seu trabalho Gestão: elementos de uma realidade vivenciada, têm como objeto de estudo o conceito de gestão que vem sendo instituído pela Secretaria de Estado da Educação do Estado de São Paulo a partir de meados da década de 1990, através de uma leitura da constituição da sociedade capitalista visando compreender a forma de gerir o setor público, em específico da educação no Estado de São Paulo.

    Com o artigo O cultivo de valores exemplares: "galeriados patronos de escolas", de Antonio d’Avila (1980-1989 aprofessora Thabatha Aline Trevisan contribui para a história da educação brasileira e para o campo da imprensa periódica pedagógica. Neste artigo, destacam-se a produção de biografias, uma contribuição do educador Antônio d´Ávila para o periódico Jornal dos Professores, publicação do Centro do Professorado Paulista (CPP.

    A professora Dóris Bittencourt Almeida, com o artigo As memórias e a história da educação: aproximações teórico e metodológicas, reflete sobre as contribuições da memória e da história oral para a história da educação. Tais reflexões foram fundamentais na construção de um estudo referente à formação docente rural, durante as décadas de 1950 e 1960. Assim, por meio da metodologia da história oral, procurou analisar o processo de memória de sujeitos discentes e docentes da Escola Normal Rural de Osório/RS, a partir dos discursos e dos conteúdos de verdade produzidos em entrevistas.

Os dados meteorológicos e as informações topográficas são processados pelos pré-processadores AERMET e AERMAP, respectivamente, para serem introduzidos no modelo AERMOD. Porém, antes os dados meteorológicos de superfície e altitude são processados por programas desenvolvidos em linguagem FORTRAN 90, para transformar as informações para o formato de processamento do modelo AERMET. As informações de terreno foram transformadas em um arquivo digital (DEM com resolução de 90 metros, para depois serem processadas pelo AERMAP. Foi realizada a comparação entre os resultados estimados da altura da camada de mistura com dados experimentais obtidos da radiossondagem da atmosfera da estação do Galeão, disponibilizado pela INFRAERO.

Em “Contribuição das ciências cognitivas e da ciência da informação para representação da informação: proposta para utilização na construção de biblioteca virtual temática em saúde” de Leandro Guedes da Fonseca, Iara Rodrigues de Amorim, Regina Goulart Lourenço e Jorge Calmon de Almeida Biolchini focalizam Ciências Cognitivas que podem aprimorar a representação da informação na construção de bibliotecas virtuais temáticas na área da Saúde. Destacam, também, características e funcionalidades desejáveis para uma biblioteca virtual temática e a importância do caráter interdisciplinar das áreas, com vistas ao aprimoramento de produtos e serviços de informação em benefício do usuário. Já em “A intervenção humana na qualificação de processos de data mining: estudo de caso em uma base de dados hipotética” os autores Juliano Tonizetti Brignoli, Egon Sewald Junior, Viviane Brandão Miguez, Neri dos Santos e Fernando Spanhol exploram as contribuições da intervenção de analistas humanos em processos de Data Mining. Enfatizam as propriedades da intelectualidade humana, como a inferência e a percepção que propiciam excelente complementação aos processos de análise de dados. Usando um estudo de caso baseado em simulação pretende-se validar proposições que asseguram o fato dos processos de Data Mining ser conduzidos e interpretados por analistas humanos, tornando-os assim, de característica dinâmica. O artigo “Ontologia: ambiguidade e precisão” de José Marcelo Schiessl e Marisa Bräscher enfatizam ambiguidade como um grande obstáculo para a recuperação de informação. Enfatizam as diversas

Os autores concluem que as duas filiais têm de fato atuação compatível com os preceitos que orientam a prática das organizações sociais e que os mecanismos de marketing podem contribuir para que empresas, usando esse tipo de atuação, possam contribuir para o benefício da empresa e da sociedade. E, last but not least, muito pelo contrário, Sylvia Therezinha de Almeida Moraes, Angela da Rocha e Jorge Ferreira da Silva, em “Uso de redes no decorrer do processo de internacionalização: Estudo longitudinal no setor de software” buscam entender como empresas brasileiras de software acessam redes de parceiros internacionais e as utilizam ao longo do tempo em seu processo de internacionalização. Por meio de estudo longitudinais com quatro díades de empresas, cada uma formada por uma empresa brasileira e sediada no exterior, identificam que a sequência de etapas pelas quais passam os relacionamentos permitem falar em dois processos genéricos de evolução desses relacionamentos: Um que é seguido pela empresa nacional no relacionamento com multinacionais e outro que acontece quando a empresa se relaciona com outra de porte similar ao seu. O estudo traz contribuições ao entendimento de como se iniciam e evoluem redes de relacionamento internacional, principalmente no que concerne a influência do tamanho dos parceiros envolvidos. Não bastasse isso, constitui-se em um excelente exemplo de como descrever e analisar um processo longitudinal a partir de estudos de casos múltiplos. Ilan Avrichir Editor-Chefe

    a um conjunto de ações relativas ao tratamento arquitetônico e urbanístico. Na esteira desse processo e a exemplo de outras grandes cidades brasileiras, a cidade do Recife tem sido palco de algumas experiências inovadoras, sob a égide da busca de padrões de melhor qualidade de vida e de inserção no cenário econômico contemporâneo. Os bairros de sua área central sobretudo os do Recife e de São José - são exemplos de diferentes concepções de 'revitalização" desde metade dos anos 1980 e com maior intensidade a partir de 1994, apresentando, objetivos e resultados distintos, mas guardando em comum, a perspectiva da seletividade sócio-espacial. Privilegia-se, assim, alguns setores em detrimento de outros, indesejáveis e/ou incompatíveis com a concepção hegemônica de desenvolvimento. Territorialidades religiosas, comerciais, sexuais, entre outras, são reeditadas - ou reprimidas neste fim de século sob múltiplos arranjos e formas. A partir de dois setores "revitalizados' pela Prefeitura da Cidade do Recife - a rua do Bom Jesus (Bairro do Recife e Av. Dantas Barreto (bairros de Santo Antônio e de São José - são analisadas neste trabalho permanências e mudanças sócio-espaciais verificadas na área central da cidade a partir de territorialidades de seus freqüentadores, visando verificar os efeitos de planos de revitalização nas relações cotidianas da população com os espaços centrais. Ao analisar tais práticas neste trabalho, pretende-se evocar a necessidade da apreensão da realidade urbana sob diversos ângulos de sua complexidade - incluindo a dimensão cotidiana - destacando a importância de agentes co-participantes nesses processos de requalificação sócio-espacial, enquanto fontes significativas no estudo das cidades contemporâneas.

Estas anisotropias estão relacionadas a três superfícies preferenciais de corte, usualmente adotadas na prática de desmontes controlados com o objetivo de otimizar a operação. A caracterização das anisotropias abordou uma das principais características envolvidas no processo de desmonte controlado: a energia necessária para se criar uma nova superfície segundo uma orientação pré-determinada. A avaliação dos resultados de ensaios indiretos de resistência à tração e tenacidade à fratura, realizados para dois grupos de amostras de rochas graníticas com texturas distintas, permitiu que algumas conclusões fossem obtidas. A determinação da resistência à tração através do método indireto sugerido pela I.S.R.M. (1981 não se mostrou adequada. Os resultados apresentaram acentuada variabilidade, o que inviabilizou qualquer possibilidade de caracterização de um comportamento anisotrópico. Por outro lado, a tenacidade à fratura das rochas se confirmou como a propriedade mecânica com maior influência no comportamento anisotrópico das rochas ensaiadas. Os resultados mostraram-se bastante conclusivos, apontando claramente um comportamento mecânico diferenciado, segundo cada uma das três superfícies de corte investigadas. Entre as duas metodologias empregadas neste estudo, para a caracterização da energia necessária para criação de uma nova superfície, a metodologia proposta pela I.S.R.M. (1994 para a determinação da tenacidade à fratura usando discos semelhantes aos adotados
