    La biopsia rápida intraoperatoria es un examen esencial en el curso de una tiroidectomía para decidir la magnitud del procedimiento resectivo. Un patólogo experimentado va a redundar en un alto grado de concordancia en el resultado entre la biopsia rápida y el de la biopsia diferida. Para analizar cómo se dio esta concordancia en nuestro hospital, revisamos retrospectivamente 351 tiroidectomías, de las 795 realizadas en los últimos 10 años en nuestro Servicio.

    Full Text Available A matéria prima da poesia de Manoel de Barros tem seus limites no chão do Pantanal Matogrossense, um mundo primitivo prenhe de riqueza visual, tátil, olfativa, permeado pelo humor, pela busca do ínfimo, do pequeno. Nesse trabalho, porém, o objetivo é a Metapoesia, sua preocupação com o próprio fazer poético. Na obra de Barros há forte incidência de poemas metalinguísticos nos quais a mensagem está centrada no código, indicando a Função Metalinguística, Chalub, 1986. Neste trabalho, será apresentado um estudo comparativo entre três poemas de Manoel de Barros: “No Tratado das Grandezas do Ínfimo” da obra O livro das ignorãças, 1994, “Nascimento da palavra” da obra Gramática expositiva do chão, 1990 e “Eu sou o medo da lucidez” da obra O guardador de águas, 1989, buscando-se pelos elementos da natureza e avaliando sua importância na constituição de fazer poético do autor.

  5. Mikhail Bakhtin and Manoel de Barros: between Chronotope and Childhood

    Directory of Open Access Journals (Sweden)

    Paloma Dias Silveira

    2015-04-01

    Full Text Available This article addresses childhood, time and space through literature and philosophy. We begin with the assessment of Mikhail Bakhtin that leads to the formation of the concept of chronotope, analyzing the work of François Rabelais in the context of grotesque realism. Bakhtin constructs a philosophical perspective of open and collective time-space, freedom, and creation. In turn, the literature of Manoel de Barros embodies a chronotope, cementing a view of the world and men in contrast with meanings and values. This brings us to the understanding that Barros's poems portray a particular aesthetics similar to that assessed by Bakhtin. Barros's aesthetics is governed by a time-space relationship that associates childhood with creation, the time-space of uselessness and contemplation, the lowering of the gaze, rebirth and the creation of proximities between heterogeneous elements.

    A recent empirical study conducted by Robert Barro and published by the Bank of England finds surprisingly little evidence for harmful effects of inflation on growth, seemingly refuting the many theories purporting the contrary. Have the costs of inflation been exaggerated in the past? Is inflation in fact essentially harmless?

    Classical game theory addresses decision problems in multi-agent environment where one rational agent's decision affects other agents' payoffs. Game theory has widespread application in economic, social and biological sciences. In recent years quantum versions of classical games have been proposed and studied. In this paper, we consider a quantum version of the classical Barro-Gordon game which captures the problem of time inconsistency in monetary economics. Such time inconsistency refers to the temptation of weak policy maker to implement high inflation when the public expects low inflation. The inconsistency arises when the public punishes the weak policy maker in the next cycle. We first present a quantum version of the Barro-Gordon game. Next, we show that in a particular case of the quantum game, time-consistent Nash equilibrium could be achieved when public expects low inflation, thus resolving the game.

    1995-01-01

    Full Text Available Foraging behavior and partitioning of foraging areas of Odonomachus bauri were investigated on Barro Colorado Island in Panama. The activity of the ants did not show any daily pattern; foragers were active day and night. The type of prey captured by O. bauri supports the idea that in higher Odontomachus and Anochetus species, the high speed of mandible closure serves more for generating power than capturing elusive prey. Polydomous nests may enable O. bauri colonies to enlarge their foraging areas.

    Júlio César Alexandre Júnior

    2018-02-01

    Full Text Available The scope of this work is to analyze comparatively the poetry of the Mato Grosso poet Manoel de Barros with work La trahison des images by the Belgian artist René Magritte. It’s noted that the Poetry of Manoel de Barros carries in itself marks of the Surrealism, worked in development with the language: its destruction and recreation of words that surpass the logical reality, reaches the great transcendence of the Universe, by means of an exercise of Poetry. By practicing poetic Manoelino, words organize, intertwine, merge, in a tangle of odd images, to surreal taste. Already Magritte was a poet of painting and the word surrealist, playing with painting and verb, banality and arbitrariness between painting and word. The main objective of this work is to analyze the painting of Magritte in comparison to the art of poetry of Barros that presents in his work minute objects, of the daily, creation of metaphors, with an inaugural language, totally illogical as it does with the painting of the Belgian artist.

    Full Text Available A poética de Manoel de Barros é marcada por um experimentalismo que enaltece a sinfonia de vozes com as quais o poeta dialoga. Nesse sentido, a obra de Manoel de Barros apresenta elementos que apontam para uma poética articuladora de um projeto estético subjacente à sua obra e encaminha-se no sentido da consolidação de uma ars poetica própria que norteia os valores estéticos e éticos do poeta. Logo, o problema do presente trabalho busca saber como Manoel de Barros introduz, na tessitura de sua poesia, reflexões espaciotemporais que perpassam a história circunstancial e a história literária. Marcado pelas tensões de uma consciência crítica, procuramos evidenciar como o poeta estabelece relação com a tradição e a contemporaneidade.

    O estudo sobre o discurso da norma na Gramática de João de Barros é parte de uma pesquisa em desenvolvimento acerca do discurso da norma em gramáticas da língua portuguesa, do século XVI à atualidade, no âmbito do projeto coletivo "História das idéias linguisticas no Brasil: ética e política das línguas". As gramáticas são analisadas como discursos, na perspectiva teórica e metodológica da semiótica discursiva francesa. São examinados, particularmente, três procedimentos discursivos: as modalizações dos sujeitos e dos objetos, que constituem três tipos de discursos da norma - a norma natural, predominante em João de Barros, a norma prescritiva e a norma usual - ; as projeções enunciativas de pessoa e de tempo na gramática em exame; as relações intertextuais entre o discurso da norma na gramática e os discursos gramaticais da época, com que João de Barros concorda, e também com o discurso colonialista português, o da Monarquia e o da Igreja, da época, discursos que sua gramática ajuda a construir, sobretudo pelos exemplos.

    Paloma Dias Silveira

    2015-04-01

    Full Text Available Neste artigo aproximamos a infância, o espaço e o tempo através da literatura e da filosofia. Partimos da leitura que Bakhtin faz das obras de François Rabelais, no contexto do realismos grotesco, e do conceito de cronotopo aí formulado. Bakhtin constrói uma perspectiva filosófica de espaço-tempo aberto e coletivo, de liberdade e criação. A literatura de Manoel de Barros, por sua vez, materializa um cronotopo, afirmando uma visão de mundo e de homem no embate entre sentidos e valores. Chegamos ao entendimento de que os poemas de Barros possuem uma estética particular que se aproxima daquela analisada por Bakhtin. É regida por uma relação espaço-temporal que trabalha com a infância associada à criação, envolvendo o espaço-tempo do inútil e da contemplação, o rebaixamento do olhar, o renascimento e a produção de vizinhanças entre elementos heterogêneos.

Haciendo uso de las teorías del cuerpo de Hélene Cixous y de Luce Irigaray, el ensayo examina los distintos modos en que estos cuentos encaran la necesidad de re-concebir y re-escribir, desde la diferencia genérica, la experiencia erótica de un grupo heterogéneo de mujeres. Semiologies of Desire in "Signos bajo la Piel" Starting from the premise that the author of "Signos bajo la piel" seeks the reinvention of body language as eroticized when viewed from a post feminist perspective, this study explores the representation of desire in the stories of Pia Barros. By making use of the theory of the body of Helena Cixous and Luce Irigaray, this analysis centers on the dif.ferent modes in which the stories confront the need to re-conceive and re-write, from the generic dif.ference, the ero tic experience of a heterogeneous group ofwomen.

  6. Textural and microstructural development of the Barro Alto Complex: implications for seismic anisotropy

    Crustal rheology is associated with the behavior of its constituents in response to stress and strain, while the seismic anisotropy is a property that can correlate these parameters. Seismic properties are strongly related to the microstructures and crystallographic preferred orientation (CPO) of the rocks. In this work, we study CPO-derived seismic anisotropy of metamorphosed gabbro-norites from the Barro Alto (Brazil central) layered complex. The EBSD technique was employed to analyze the crystallographic orientation of the main mineral assembly, diopside and feldspar. The Barro Alto complex belongs to the Tocantins Structural Province, developed between the Amazon and São Francisco cratons, during the Neoproterozoic Brasiliano orogenic cycle. This complex was formed by a mafic-ultramafic layered intrusion mylonitized and metamorphosed under granulite facies conditions. The mylonitic foliation shows compositional segregation into felsic and mafic bands. The samples are composed of porphyroclasts of plagioclase and diopside in a fine matrix of plagioclase, clinopyroxene, orthopyroxene and, less commonly, amphibole and biotite. The plagioclase porphyroclasts exhibit undulose extinction and core-mantle structure. In fine matrix samples the poles to a(100), b(010) and c(001) are randomly distributed in both phases. However, for increasing matrix grain size plagioclase grains shows maxima of a(100) poles sub-parallel to the foliation and b(010) normal to the foliation. The low value of the J index (2.4 for plagioclase and 1.8 for diopside) indicates poorly developed fabric. Misorientation profiles showing high frequency of small angle boundaries are typical of recrystallization by subgrain rotation mechanisms. The microstructural and CPO analyses suggest deformation controlled by diffusive processes. The CPO models were compared to models described in the literature, based on the anorthite + diopside assembly, since these are the major phases, and thus control the

  7. Demography and natural history of the common fruit bat, Artibeus jamaicensis, on Barro Colorado Island, Panama

    Science.gov (United States)

    1991-01-01

    Bats were marked and monitored on Barro Colorado Island, Panama, to study seasonal and annual variation in distribution, abundance, and natural history from 1975 through 1980. Data gathered advances our knowledge about flocking; abundance; feeding strategies; social behavior; species richness; population structure and stability; age and sex ratios; life expectancy and longevity; nightly, seasonal, and annual movements; synchrony within and between species in reproductive activity; timing of reproductive cycles; survival and dispersal of recruits; intra-and inter-specific relationships; and day and night roost selection. Barro Colorado Island (BCI) harbors large populations of bats that feed on the fruit of canopy trees, especially figs. These trees are abundant, and the individual asynchrony of their fruiting rhythms results in a fairly uniform abundance of fruit. When figs are scarce, a variety of other fruits is available to replace them. This relatively dependable food supply attracts a remarkably rich guild of bats. Although we marked all bats caught, we tried to maximize the number of Artibeus jamaicensis netted, because it is abundant (2/3 of the total catch of bats on BCI), easily captured by conventional means (mist nets set at ground level), and responds well to handling and marking. An average Artibeus jamaicensis is a 45 g frugivore that eats roughly its weight in fruit every night. These bats prefer figs and often seek them out even when other types of fruit they might eat are far more abundant. They commute several hundred meters to feeding trees on the average, feeding on fruit from one to four trees each night, and returning to a single fruiting tree an average of four nights in succession. The bats tend to fly farther when fewer fig trees are bearing ripe fruit, and they feed from fewer trees, on the average, when the moon is nearly full. These bats, like their congeners, do not feed in the fruiting tree itself. Instead, they select a fruit and

Recientemente, han sido reportados de causar efectos adversos sobre la vida silvestre y humana. Además, la mayoría de estos compuestos derivan en plantas de tratamiento de aguas residuales, donde pueden sufrir procesos de biodegradación, sorción en biomasa o stripping.Muchas investigaciones relevantes han sido realizadas para el estudio de la degradación de PPCPs, no obstante, la información sobre el proceso de sorción es limitada. Por lo tanto, es objetivo de este trabajo resumir el estado de conocimiento sobre el tema, a los efectos de establecer su estado actual y aclarar necesidades en materia de investigación y direcciones.La inspección del material disponible arroja resultados positivos relacionados al entendimiento de los mecanismos involucrados. Sin embargo, se ha determinado que la sorción de muchos PPCPs en la biomasa no es ideal, sino un proceso relativamente complejo. Como resultado de esta complejidad los modelos simplificados propuestos no logran una descripción completa, más aún, la predicción del particionado ambiental no es suficientemente precisa en algunos casos.Un estudio más detallado del proceso de adsorción de PPCP en barros activados es necesario para mejorar los modelos propuestos en diversos trabajos y optimizar la predicción del particionado. La información de la sorción de PPCP, sus metabolitos, y la competencia entre ellos, aún no es suficiente para ser incorporada en dichos modelos.

    Full Text Available En este trabajo se presentan los resultados de los estudios realizados empleando barros efluentes de la producción de ácido bórico, a partir de ulexita como materia prima, para la obtención de productos de barro cocido en reemplazo de la arcilla tradicional, aprovechando la característica de fundentes que poseen los boratos. Los barros efluentes (ácidos y con elevado contenido en boro de la industria boratera generalmente se acumulan en diques, lo cual genera riesgo medioambiental. El uso de efluentes como materia prima para la obtención de nuevos productos es una alternativa para minimizar dicho riesgo. Se moldearon ladrillos de barro con los que se estudió la influencia de la temperatura de cocción sobre las propiedades mecánicas y la solubilidad de boro y otras sales en agua. Los resultados muestran que la cocción del barro es una alternativa válida para la obtención de productos útiles, tales como ladrillos, tejuelas, cerámica rústica, alfarería.

Desde el punto de vista experimental se incineraron los barros cloacales en un lecho fluidizado. El trabajo se focalizó en el comportamiento de tres metales tóxicos representativos: Cd, Pb y Zn. Los resultados de este estudio permiten concluir, desde el punto de vista termodinámico, que la co-combustión con residuos sólidos municipales no favorecería la vaporización de los elementos traza, ya que los cloruros metálicos reaccionarían con el agua formando óxidos y serían retenidos por la matriz mineral. El estudio experimental nos muestra que la vaporización de los metales pesados es altamente dependiente de las condiciones de operación.

    Marcus Barros talks about how tropical diseases influenced his decision to study medicine. He tells a number of stories about his family, which moved from Alto Juruá to Manaus to escape malaria and other fevers. He says it is essential to adopt homeopathy, acupuncture, and other indigenous knowledge and practices in treating disease. Barros also talks about measures taken when he was president of Brazil's national environmental institute, Instituto Brasileiro do Meio Ambiente e dos Recursos Naturais Renováveis (Ibama)--all part of an effort to prevent and combat these diseases and halt deforestation and burn-offs.

    Full Text Available Development banks are key actors in climate finance. During the last decades, they have increased the funding of climate change related projects, especially those under the Clean Development Mechanism (CDM. Defined in Article 12 of the Kyoto Protocol, the CDM aims at contributing to climate change mitigation while assisting in achieving sustainable development. However, many CDM projects have caused environmental damage and human rights abuses that especially affect the most vulnerable people. Located in Panama, the Barro Blanco hydro-power dam exemplifies the complex interrelationship of climate financing, development policies, the political and economic national context and human rights. Through the analysis of the role of development banks in climate finance, especially in the context of CDM projects, this paper aims (1 to clarify the role of development banks in climate finance, (2 to shed light on the vulnerable situation of the people affected by these projects, (3 to highlight the gaps in both the CDM rules and the development banks’ safeguard policies concerning the protection of human rights and the prevention of environmental abuses, and (4 to give a current example of this complex situation through the Barro Blanco case study. This paper argues that the manifold and often competing national and international legal and political layers of climate change mitigation projects repeatedly leave project affected people vulnerable to human rights violations without adequate safeguards and mechanisms to effectively articulate their interests, protect their rights and promote access to justice.

  16. Predispersal home range shift of an ocelot Leopardus pardalis (Carnivora: Felidae on Barro Colorado Island, Panama

    Directory of Open Access Journals (Sweden)

    2008-06-01

    Full Text Available Home range shifts prior to natal dispersal have been rarely documented, yet the events that lead a subadult to abandon a portion of its home range and venture into unfamiliar territories, before eventually setting off to look for a site to reproduce, are probably related to the causes of dispersal itself. Here, we used a combination of manual radio-tracking and an Automated Radio Telemetry System to continuously study the movements of a subadult male ocelot (Leopardus pardalis, a solitary carnivore with sex-biased dispersal, on Barro Colorado Island, Panama, for 18 months from May 2003 through October 2004. The subadult ocelot’s parents were also radio-tracked to record possible parent-offspring interactions within their home ranges. At the age of ca. 21 months the subadult gradually began to shift its natal home range, establishing a new one used until the end of the study, in an area that had previously been used by another dispersing subadult male. Only three parent-offspring interactions were recorded during the four months around the time the range-shift occurred. The apparent peaceful nature of these encounters, along with the slow transition out of a portion of his natal home range, suggest the subadult was not evicted from his natal area by his parents. The timing of the shift, along with the subadult’s increase in weight into the weight range of adult ocelots four months after establishing the new territory, suggests that predispersal home range shifts could act as a low risk and opportunistic strategy for reaching adult size, while minimizing competition with parents and siblings, in preparation for an eventual dispersal into a new breeding territory.

  19. A New Basal Sauropodomorph (Dinosauria: Saurischia) from Quebrada del Barro Formation (Marayes-El Carrizal Basin), Northwestern Argentina

    2011-01-01

    Background Argentinean basal sauropodomorphs are known by several specimens from different basins; Ischigualasto, El Tranquilo, and Mogna. The Argentinean record is diverse and includes some of the most primitive known sauropodomorphs such as Panphagia and Chromogisaurus, as well as more derived forms, including several massospondylids. Until now, the Massospondylidae were the group of basal sauropodomorphs most widely spread around Pangea with a record in almost all continents, mostly from the southern hemisphere, including the only record from Antarctica. Methodology/Principal Finding We describe here a new basal sauropodomorph, Leyesaurus marayensis gen. et sp. nov., from the Quebrada del Barro Formation, an Upper Triassic-Lower Jurassic unit that crops out in northwestern Argentina. The new taxon is represented by a partial articulated skeleton that includes the skull, vertebral column, scapular and pelvic girdles, and hindlimb. Leyesaurus is diagnosed by a set of unique features, such as a sharply acute angle (50 degrees) formed by the ascending process of the maxilla and the alveolar margin, a straight ascending process of the maxilla with a longitudinal ridge on its lateral surface, noticeably bulging labial side of the maxillary teeth, greatly elongated cervical vertebrae, and proximal articular surface of metatarsal III that is shelf-like and medially deflected. Phylogenetic analysis recovers Leyesaurus as a basal sauropodomorph, sister taxon of Adeopapposaurus within the Massospondylidae. Moreover, the results suggest that massospondylids achieved a higher diversity than previously thought. Conclusions/Significance Our phylogenetic results differ with respect to previous analyses by rejecting the massospondylid affinities of some taxa from the northern hemisphere (e.g., Seitaad, Sarahsaurus). As a result, the new taxon Leyesaurus, coupled with other recent discoveries, suggests that the diversity of massospondylids in the southern hemisphere was higher

    Full Text Available The aim of this study is to describe and analyze how the managerial competences are configured and managed in the retail sector of Barro Preto’s fashion district in managers and other sales team members’ perception. In order to accomplish this, we took into account Paiva’s competence model (Paiva, 2007. The field research was characterized as a descriptive case study, with a qualitative approach. The data were collected through documentation survey and analysis and by interviews. The subjects were chosen using accessibility and convenience criteria. The data collected were organized, processed and analyzed by the technique of content analysis. Subsequently, the demographic and functional data of respondents were presented. For most of the inverviewees, the notion of competence is linked to action; they are aware that managers occupy a middle ground in the organizational hierarchy and that they work in an environment known by ambiguity, contradictions and demands. So, to be competent managers, interviewees attested the need for academic training, while considering the importance of experience. This study suggests the importance of informal learning in the managers’ competences training and development, especially through the figure of the "model manager"; in other words, the one that is considered the mirror to the other members of the sales team. Finally, limitations of this study and suggestions for further research were pointed out.

  2. Archosauriform remains from the Late Triassic of San Luis province, Argentina, Quebrada del Barro Formation, Marayes-El Carrizal Basin

    Here we present archosauriform remains from 'Abra de los Colorados', a fossiliferous locality at Sierra de Guayaguas, NW San Luis Province. Two fossiliferous levels were identified in outcrops of the Quebrada del Barro Formation (Norian), which represent the southernmost outcrops of the Marayes-El Carrizal Basin. These levels are composed by massive muddy lithofacies, interpreted as floodplain deposits. The specimens consist of one incomplete maxilla (MIC-V718), one caudal vertebra (MIC-V719), one metatarsal (MIC-V720) and one indeterminate appendicular bone (MIC-V721). The materials can be assigned to Archosauriformes but the fragmentary nature and lack of unambiguous synapomorphies preclude a more precise taxomic assignment. The maxilla is remarkably large and robust and represents the posterior process. It preserved one partially erupted tooth with ziphodont morphology. This bone shows some anatomical traits and size match with 'rauisuchians' and theropods. MIC-V719 corresponds to a proximal caudal vertebra. It has a high centrum, a ventral longitudinal furrow, expanded articular processes for the chevrons, a posteriorly displaced diapophysis located below the level of the prezygapophyses, and short prezygapophyses. This vertebra would be from an indeterminate archosauriform. MIC-V720 presents a cylindrical diaphysis, with a well-developed distal trochlea, which present resemblances with metatarsals of theropods, pseudosuchians, and silesaurids, although the size matches better with theropods. MIC-V721 has a slender diaphysis and a convex triangular articular surface, and corresponds to an indeterminate archosauriform. Despite being fragmentary, these materials indicate the presence of a diverse archosauriforms association from Late Triassic beds of San Luis. Thus, they add to the faunal assemblage recently reported from this basin at San Juan Province, which is much rich and diverse than the coeval paleofauna well known from Los Colorados Formation in the

    The author presents a comparative analysis of results obtained in a follow-up study of the 1st 12 months following insertion immediately postpartum (following delivery) of the TCu200 and IPCS 52 IUDs in a group of 400 women. The devices were inserted either manually or by using a plastic insertion aid at the maternity unit of the Barros Luco-Trudeau Hospital, Santiago, Chile, between November 1978-February 1980. The devices were retained during the 1st 12 months in 86.1% of the cases in which the TCu200 was inserted manually, 86.3% of cases in which they were inserted using the plastic aid, 59.3% of those cases in which the IPCS devices were inserted manually, and 57.2% of cases in which the IPCS was inserted using the aid. The different levels of retention among the 2 groups was due mainly to the high levels of expulsion in the IPCS 52 patients. The expulsion levels in the TCu200 groups were 9.2 and 8.1% respectively and 35.8 and 35.2% in the IPCS 52 groups. Although an IUD contraceptive system involving progesterone was selected in order to reduce bleeding and pain associated with the IUD, the incidence of such reactions was no lower in the IPCS 52 groups than in the others. However, specific levels of dysmenorrhea were significantly lower (p0.05) among IPCS 52 groups than among TCu200 groups. In general, results obtained with the TCu200 were better than those obtained with the IPCS 52, and the insertion method had no influence on the recorded reactions. (author's modified)

    Full Text Available Sand flies (Diptera, Psychodidae, Phlebotominae in the genus Lutzomyia are the predominant vectors of the protozoan disease leishmaniasis in the New World. Within the watershed of the Panama Canal, the cutaneous form of leishmaniasis is a continuous health threat for residents, tourists and members of an international research community. Here we report the results of screening a tropical forest assemblage of sand fly species for infection by both Leishmania and a microbe that can potentially serve in vector population control, the cytoplasmically transmitted rickettsia, Wolbachia pipientis. Knowing accurately which Lutzomyia species are present, what their evolutionary relationships are, and how they are infected by strains of both Leishmania and Wolbachia is of critical value for building strategies to mitigate the impact of this disease in humans.We collected, sorted and then used DNA sequences to determine the diversity and probable phylogenetic relationships of the Phlebotominae occurring in the understory of Barro Colorado Island in the Republic of Panama. Sequence from CO1, the DNA barcoding gene, supported 18 morphology-based species determinations while revealing the presence of two possible "cryptic" species, one (Lu. sp. nr vespertilionis within the Vespertilionis group, the other (Lu. gomezi within the Lutzomyia-cruciata series. Using ITS-1 and "minicircle" primers we detected Leishmania DNA in 43.3% of Lu. trapidoi, 26.3% of Lu. gomezi individuals and in 0% of the other 18 sand fly species. Identical ITS-1 sequence was obtained from the Leishmania infecting Lu. trapidoi and Lu. gomezi, sequence which was 93% similar to Leishmania (viannia naiffi in GenBank, a species previously unknown in Panama, but recognized as a type of cutaneous leishmaniasis vectored broadly across northern and central South America. Distinct strains of the intracellular bacterium Wolbachia were detected in three of 20 sand fly species, including Lu. trapidoi

    The influence of slaughter season and sex on intramuscular total lipids (ITL) neutral lipid (NL) and phospholipid (PL) compositions, cholesterol and α-tocopherol contents were evaluated in Biceps femoris (Bf), Longissimus dorsi (Ld) and Supraspinatus (Ss) muscles from 92 Barrosã-PDO (Protected Denomination of Origin) calves. ITL content in Bf muscle was affected by slaughter season and sex whereas NL content was only affected by slaughter season. Neither sex nor slaughter season influenced cholesterol and α-tocopherol contents in the muscles under study. Concerning NL composition, sex was an important source of variation on the proportions of total SFA and MUFA in all muscles. Irrespective of the considered muscle, males had higher total SFA but lower total MUFA and MUFA/SFA contents than females. Slaughter season influenced C18:2 cis-9 trans-11 (CLA) content in Bf (P<0.01) and in Ss muscles (P<0.05) with calves slaughtered in autumn showing higher values than their counterparts. Total MUFA, n-3 PUFA and n-6/n-3 ratio contents in Ld muscle were also affected by slaughter season. Regarding PL composition, slaughter season×sex interaction affected total SFA, PUFA/SFA and n-6 PUFA contents in Bf and Ss muscles. In addition, this interaction influenced total MUFA (P<0.05) in Bf muscle and total PUFA (P<0.01) in Ss muscle. CLA content in PL from Ld was influenced by sex (P<0.05) and by slaughter season (P<0.01), with females slaughtered in autumn presenting the highest content. These results clearly indicate that sex and slaughter season are important factors that influence the fatty acid composition of Barrosã-PDO veal.

Este tipo de trabalho, de um modo geral, emprega pessoas capazes de suportar serviços pesados, excluindo desta forma mulheres, idosos e portadores de deficiência. O Projeto Caminhos de Barro, implantado pela Universidade Estadual do Norte Fluminense Darcy Ribeiro (UENF, no ano de 2000, tem como finalidade capacitar, na arte cerâmica artesanal, essas comunidades excluídas do processo industrial de produção de tijolos e telhas. O presente trabalho tem como primícia contribuir para uma melhora na tecnologia adotada, pela primeira geração de artesãs formada na Oficina Caminhos de Barro, adequando a matéria prima utilizada à nova atividade através de mapeamento, classificação e caracterização dos materiais da região na forma in natura, ocupando-se, igualmente do seu comportamento após a queima. A mesma análise técnica utilizada para caracterização e adequação dos produtos industrializados pelas industrias cerâmicas mostrou-se também adequada para o artesanato. A matéria prima estudada, em principio, apresentou as qualidades necessárias ao trabalho artesanal como pode ser observado pelos produtos obtidos levando a um menor grau de perda. Porém a criação de um padrão mais adequado de matéria prima a ser utilizado na arte cerâmica da baixada campista demandará, portanto, mais tempo, recursos e estudo, pois as propriedades desejadas de cada artefato tais como: cor, permeabilidade e acabamento podem estar associados a pequenas variações físicas e mineralógicas.The industrial park of the Campos dos Goytacazes is formed for more than one hundred ceramics, absorbing, by mean information of the proper segment, about 5000 employees.

Los nidos estaban distribuidos uniformemente a través de toda la parcela, y se asociaban de manera significativa con el tipo de hábitat, existían más nidos de los esperados en las planicies altas y en la sección de bosque más joven de la parcela. La densidad promedio era de 6.2 nidos por hectárea. Los nidos con un mayor número de vecinos entre 0 y 20 m de distancia, tenían una mayor probabilidad de morir, si se comparaban con aquéllos que se encontraban separados por distancias mayores. La mortalidad era entre 13.36 y 69.64% dependiendo del intervalo de censo, y el reclutamiento fue del 22.63 y 31.72%. Los nidos se encontraron en las bases de 84 especies de plantas, en 34 familias con cuatro categorías de forma de vida: 76 especies eran árboles, 5 especies eran arbustos, 2 especies eran palmas y 1 era liana. Ocho especies de plantas se asociaban positivamente con los nidos de la hormiga. Plantas medianas entre 8 y 63.9 cm de DAP eran las más utilizadas. Arboles y arbustos pequeños presentan muy poca asociación con los nidos. La hormiga no se asocia con árboles que tienen nectarios extraflorales. El 53% de los nidos tenían a Phrynus gervaisii (Amblypygi: Phrynidae habitando en el interior. Estos nidos presentaron menores tasas de mortalidad en comparación con el resto.We studied the distribution, mortality and association with plants, of 308 nests of the neotropical ant Paraponera clavata, in a permanent 50 hectare plot in old-growth forest on Barro Colorado island between September 1993 and February 1995.

    During the finishing phase of bovines, large amounts of subcutaneous and visceral fats are deposited leading to production inefficiencies with major impact on meat quality. A better understanding of the cellularity features of the main fat depots could provide strategies for adipose tissue manipulation. This study assessed the effect of feeding diets with distinct forage to concentrate ratios on the cellularity of two fat depots of beef cattle and their implications on the fatty acid profile. Thus, two phylogenetically distant Portuguese bovine breeds, Alentejana and Barrosã, were selected. The results did not show differences in subcutaneous fat deposition nor in visceral fat depots partitioning. Plasma adipokines concentration failed to show a consistent relationship with fatness, as leptin remained constant in all experimental groups, whereas interleukin-6 was influenced by breed. Fat depot seems to determine the area and number of adipocytes, with larger adipocytes and a lower number of cells in subcutaneous fat than in mesenteric fat. Neither breed nor diet influenced adipocytes area and number. The contents of total fatty acids, partial sums of fatty acids and conjugated linoleic acid isomeric profile were affected by breed and fat depot. The incorporation of saturated fatty acids (SFA), trans fatty acids, polyunsaturated fatty acids (PUFA) and branched chain fatty acids (BCFA) was higher in mesenteric fat depot, whereas subcutaneous fat depot had greater percentages of monounsaturated fatty acids (MUFA). In addition, SFA and MUFA proportions seem to be breed-related. In spite of the less relevant role of diet, the percentages of PUFA and BCFA were influenced by this factor. Under these experimental conditions, the effect of fat depot on cellularity and fatty acid composition prevails over breed or diet, as reinforced by the principal component analysis. PMID:22253565

    Eleven species of Amazon parrots (genus Amazona) are known to occur in Brazil, and nest poaching and illegal traffic pose serious conservation threats to these species. When the illegal owners realize these animals are incompatible with their expectations and lifestyle, or when the police arrests traders and owners, these trafficked animals are often considered unfit for release and sent to local zoos and captive breeders. A retrospective survey of animal and necropsy records from 1986 to 2007 was used to evaluate the impacts of animal traffic on the population composition and mortality patterns of Amazon parrots at the Quinzinho de Barros Municipal Zoological Park, Sorocaba, Brazil. Data were obtained for 374 Amazon parrots of ten Brazilian species, and there was evidence that the studied population could be split into two major groups: a majority belonging to the Amazona aestiva species and a minority belonging to the remaining species. In comparison, the animals of the first group were more frequently admitted from traffic-related origins (98 vs. 75%), had a shorter lifespan (median 301 days vs. 848 days) and a higher mortality within the first year postadmission (54 vs. 37%), were less likely to receive expensive treatments, and were more frequently housed off-exhibit. On an average, parrots were found to have a short postadmission lifespan (median 356 days), with 92.5% of the birds dying within their first five years in captivity. The paper discusses the difficult dilemmas these incoming traffic-related animals pose to zoo management and official anti-traffic policies. © 2009 Wiley-Liss, Inc.

    Full Text Available En este trabajo se exponen los resultados de las investigaciones que se realizaron en el sitio ''El Puesto'' en el año 2005. A través del análisis espacial se establece el tipo de vinculación existente entre las estructuras y los andenes de cultivo que las circundan. La presencia de fogones en el interior de las estructuras asociados a vasijas, semillas, y restos óseos animales con signos de alteración térmica nos permiten suponer que se llevaron a cabo actividades relacionadas con la preparación, consumo y descarte de alimentos. El análisis de material lítico demuestra que existió un predominio de la realización de tareas de formatización, regularización y/o mantenimiento de instrumentos. De esta manera, sobre la base de lo expuesto anteriormente, consideramos que estos recintos nos brindan elementos importantes para empezar a definir una unidad doméstica, pues presentan una construcción definida, con un patrón específico en lo referente a sus dimensiones y técnicas constructivas; con restos artefactuales (lítico, cerámica, semillas, y restos de óseos de fauna, y un nivel de ocupación. Por último, sobre la base del análisis cerámico y de los rasgos arquitectónicos registrados en superficie proponemos como hipótesis que la cronología del sitio correspondería al período de transición entre Temprano y Medio considerado para la Provincia de La Rioja.

    For the first time, we report the characterization of triacylglycerols and fatty acids in Leucaena (Leucaena leucephala) oil [LUCO], an unexplored nontraditional non-medicinal plant belonging to the family Fabaceae. LUCO was converted to fatty acid methyl esters (FAMEs). We analyzed the triacylglycerols (TAGs) of pure LUCO and their FAMEs by time-of-flight mass spectrometry (TOF-MS) followed by multivariate analysis for discrimination among the FAMEs. Our investigations for the analysis of LUCO samples represent noble features of glycerides. A new type of ion source, coupled with high-resolution TOF-MS was applied for the comprehensive analysis of triacylglycerols. The composition of fatty acid based LUCO oil was studied using Gas Chromatography (GC-FID). The major fatty acid components of LUCO oil are linoleic acid (52.08%) oleic acid (21.26%), palmitic acid (7.91%) and stearic acid (6.01%). A metal analysis in LUCO was done by Inductively Coupled Plasma Mass Spectrometry (ICP-MS). The structural elucidation and thermal stability of LUCO were studied by FT-IR, 1H NMR, 13C NMR spectroscopic techniques and TGA-DSC, respectively. We also measured the cytotoxicity of LUCO [es

The composition of fatty acid based LUCO oil was studied using Gas Chromatography (GC-FID). The major fatty acid components of LUCO oil are linoleic acid (52.08%) oleic acid (21.26%), palmitic acid (7.91%) and stearic acid (6.01%). A metal analysis in LUCO was done by Inductively Coupled Plasma Mass Spectrometry (ICP-MS). The structural elucidation and thermal stability of LUCO were studied by FT-IR, 1H NMR, 13C NMR spectroscopic techniques and TGA-DSC, respectively. We also measured the cytotoxicity of LUCO [Spanish] Se presenta por primera vez la caracterización de triacilgliceroles y ácidos grasos del aceite de Leucaena (Leucaena leucephala) [LUCO], una planta no medicinal, no tradicional y no explorada, perteneciente a la familia Fabaceae.

    Full Text Available The notion of edified heritage best known in Brazil is represented by the big houses and others elitist buildings that goes from the colonial and imperial epoch and, in same cases, even to projects in the beginning of the twentieth century. This way, the legitimization of this notion of heritage has an important role in the process of self affirmation of the individuals, presenting as instruments of affirmation of a project of power, at the same time that it obscures and makes silence about the memory of others social groups. In this article we work with the oral history according to the Michael Pollak’s concept that gives voice to the memories of subaltern groups and makes with that the voices of subterranean memories can be heard, this way doing that the subaltern groups can be heard and having their memories preserved. The article was written using the data obtained in a rural community called Barreiro do Café, located in the municipality of São Raimundo Nonato, state of Piauí, in the Northeastern region of Brazil. These data, obtained from a research that is in the interface of Archaeology and History, demonstrate the need of widening the notion of heritage with the purpose of represent the memory of subaltern groups in the northeastern region of Brazil because they represent the regional memory that, in many times is forgotten by the authorities.

    2015-05-01

    This paper offers the concept recuperative gender strategies to describe how political leaders work to restore their public gender identities. The author examines a charity-boxing match between two Canadian politicians, Justin Trudeau and Patrick Brazeau. Trudeau is the current leader of the Liberal Party of Canada and son of former Prime Minister, Pierre Trudeau. Brazeau was a Conservative Senator. Through a discourse analysis of 222 national newspaper articles published on the match, this paper chronicles Justin Trudeau's transition from "precariously masculine" to "sufficiently masculine" and discusses the significance of this transformation for Trudeau's suitability for Liberal Party leadership. Cet article propose le concept de stratégies de récupération des sexes pour décrire et expliquer comment des dirigeants politiques travaillent à rétablir leurs identités sexuelles publiques. J'analyse la couverture médiatique du combat de boxe caritatif datant de mars 2012 et opposant deux politiciens canadiens : Justin Trudeau, le chef du Parti libéral du Canada, et Patrick Brazeau, un sénateur conservateur. En m'appuyant sur une analyse de discours de 222 articles de journaux nationaux publiés au sujet de ce combat, je détaille la transition de Justin Trudeau d'une forme de masculinité « précaire » à une « masculinité suffisante », et je discute de l'importance de cette transformation pour l'aptitude perçue de Trudeau comme chef du Parti libéral. © 2015 Canadian Sociological Association/La Société canadienne de sociologie.

  9. The non-Euclidean revolution

    CERN Document Server

    Trudeau, Richard J

    1986-01-01

    How unique and definitive is Euclidean geometry in describing the "real" space in which we live? Richard Trudeau confronts the fundamental question of truth and its representation through mathematical models in The Non-Euclidean Revolution. First, the author analyzes geometry in its historical and philosophical setting; second, he examines a revolution every bit as significant as the Copernican revolution in astronomy and the Darwinian revolution in biology; third, on the most speculative level, he questions the possibility of absolute knowledge of the world. Trudeau writes in a lively, entertaining, and highly accessible style. His book provides one of the most stimulating and personal presentations of a struggle with the nature of truth in mathematics and the physical world. A portion of the book won the Pólya Prize, a distinguished award from the Mathematical Association of America.

    The effect of the spin fluctuations on the field and temperature dependence of the magnetoresistance in ScCo 2 and LuCo 2 was studied. The experimental data where explained assuming two competing mechanisms determining the magnetoresistance of these substances. One is the 'normal magnetoresistance' caused by the influence of the Lorentz force on conduction electron trajectories. The other is due to the suppression of the spin fluctuations caused by an external magnetic field. This interplay give rise to a pronounced drop of the magnetoresistance towards the lower temperature range

  5. Phonetic and phonological perspectives on the acquisition of voice onset time by French-speaking children.

    2016-01-01

    The goal of the present article is to describe the acquisition of the phonetic details and phonological categories of stop consonants in French. To this end, the stop consonants produced by children aged 2-4 years were transcribed and acoustically analysed. Stop consonants provide an interesting window in phonetic and phonological development since they are among the first phonemes to be acquired in French (MacLeod, Sutton, Thordardottir & Trudeau, 2011), yet the mastery of the phonetic detail of these phonemes can be more drawn out (Allen, 1985). The results of the study indicate that these children are producing significant voicing contrasts between homorganic stops using voice onset time, but at the phonetic level their productions are not yet within adult ranges.

    Full Text Available Quality learning is fostered when faculty members are aware of and address student expectations for course learning activities and assessments. However, faculty often have difficulty identifying and addressing student expectations given variations in students’ backgrounds, experiences, and beliefs about education. Prior research has described significant discrepancies between student and faculty expectations that result from cultural backgrounds (1, technological expertise (2, and ‘teaching dimensions’ as described by Trudeau and Barnes (4. Such studies illustrate the need for tools to identify and index student expectations, which can be used to facilitate a dialogue between instructor and students. Here we present the results of our work to develop, refine, and deploy such a tool.

    Seabird eggs are proposed as biomonitors of chemical contamination in Chile. - Seabird eggs were used as bioindicators of chemical contamination in Chile. Brown-hooded Gull (Larus maculipennis), Kelp Gull (Larus dominicanus), Trudeau's Tern (Sterna trudeaui), Neotropic Cormorant (Phalacrocorax brasilianus), and Pink-footed Shearwater (Puffinus creatopus) eggs were sampled at different breeding sites during the 1990s. Mercury and organochlorines (PCBs, DDT, HCB, HCH, and PCP) were quantified to reveal the interspecific differences, spatial and temporal trends in contamination levels. Trudeau's Tern displayed the highest levels of mercury (486 ng g -1 wet weight). The highest ΣDDT concentrations were measured in Brown-hooded Gulls (726 ng g -1 ). PCB levels were similar among the species (102-236 ng g -1 ), but the composition of the PCB mixture was different in Pink-footed Shearwaters. With the exception of the Brown-hooded Gull, all species studied presented similar and low levels of organochlorines (ΣOHa). Residues of PCB and related compounds were not detected in any of the seabird eggs analyzed in Chile. Geographical variation was low, although levels of industrial chemicals were slightly higher in eggs from Concepcion Bay, and agricultural chemicals in eggs from Valdivia. Also interannual variation was low, but some evidence was found of decreasing levels in gull eggs throughout the time of the study. The causes of the low levels and small variability in space and time of environmental chemicals in Chilean seabirds are discussed. We propose the use of seabirds in future monitoring of the development of chemical contamination in Chile

  10. Optimality, Rational Expectations and Time Inconsistency Applied to Inflation Targeting Strategy

    Marius-Corneliu Marinas

    2008-10-01

    Full Text Available The purpose of this paper is to analyse the characteristics of an inflation targeting strategy, using the Barro-Gordon model specific tools. This paper uses the initial Barro-Gordon concepts of inflationary social costs and benefits, adding a new dimension generated by the cost of output deviating from the potential level. The main contribution of this paper is the exhaustive study of the time inconsistency problem generated by the very existence of a policymaker-established inflation rate. The mathematic simulation of a model allowed a complete analysis of several parameters’ influence (parameters such as the optimal rate of inflation, the discount rate, the importance structure of inflationary social cost on the applicable range of the target inflation rate, range that guarantees that the policymakers have no incentive to break their own rules, or at least this incentive is somewhat inferior to the future cost of doing so.

    believe that structural change is an unimportant side effect of the economic development. On the contrary, economists associated with the World Bank and some others posit that growth is brought about by the changes in sectoral composition. The objective of this study is to empirically test...... the relationship between sectoral shares and economic growth by using the panel data for 20 developed countries. The results of the granger causality suggest that both services and agriculture sectors do granger cause economic growth, whereas industrial sector does not granger cause growth. Reverse causality does...... not hold for any of the three sectors. The results of Barro and Non-Barro regressions along with the set of control variables have suggested that services sector is negatively affecting growth, whereas both industrial and agriculture shares are positively affect economic growth....

    The Local Cluster of red ceramic industry in the state of Sergipe comprises Itabaianinha-SE, Itabaiana and Baixo Sao Francisco municipalities (Propria and Santana do Sao Francisco). The city of Itabaianinha concentrates a large number of ceramics and potteries producing ceramic bricks and tiles. The study was conducted in a red ceramic industry of the region. The focus of this work was an incremental innovation in the process and product. It was analyzed three types of clays used for manufacturing of ceramic bricks (barro preto, diamante and jardim). The samples were prepared by pressing and heat treated between 600 ° C - 1100 C °. The samples characterization was by thermogravimetry, X-ray diffraction and physical tests (water absorption, linear retraction and three points flection). The clays are composed mainly of kaolinite, illite-muscovite and quartz. The results showed that the Barro Preto clay showed better results in retraction, absorption and mechanical strain. (author)

    The authors conducted 2 studies to examine the relationship between loneliness and psychosocial variables among people from Angola and Portugal. In the 1st study, the participants were 129 college students from Angola and 122 from Portugal, and in the 2nd study participants were 105 nuns from Angola and 74 from Portugal. The following instruments were administered to all participants in both studies: the Revised UCLA Loneliness Scale (D. Russell, L. Peplau, & C. Cutrona, 1980), the Neuroticism Scale (J. Barros, 1999), the Optimism Scale (J. Barros, 1998), and the Satisfaction With Life Scale (E. Diener, R. Emmons, R. Larsen, & S. Griffin, 1985). Ethnic differences were found in loneliness. The Angolan participants recorded higher scores for loneliness than did the Portuguese participants. For both samples the most prominent predictors of loneliness were neuroticism and dissatisfaction with life.

    2015-01-01

    Conjugated organic systems such as thiophene are interesting topics in the field of organic solar cells. We theoretically investigate π-conjugated polymers constituted by n units (n = 1–11) based on the thiophene (Tn) molecule. The computations of the geometries and electronic structures of these compounds are performed using the density functional theory (DFT) at the 6–31 G(d, p) level of theory and the Perdew–Burke–Eenzerhof (PBE) formulation of the generalized gradient approximation with periodic boundary conditions (PBCs) in one (1D) and two (2D) dimensions.

The absorption properties—excitation energies (E ex ), the maximal absorption wavelength (λ max ), oscillator strengths, and light harvesting—efficiency are studied using the time-dependent DFT method. Our studies show that changing the number of thiophene units can effectively modulate the electronic and optical properties.

    Conjugated organic systems such as thiophene are interesting topics in the field of organic solar cells. We theoretically investigate π-conjugated polymers constituted by n units (n = 1–11) based on the thiophene (Tn) molecule. The computations of the geometries and electronic structures of these compounds are performed using the density functional theory (DFT) at the 6–31 G(d, p) level of theory and the Perdew–Burke–Eenzerhof (PBE) formulation of the generalized gradient approximation with periodic boundary conditions (PBCs) in one (1D) and two (2D) dimensions. Moreover, the electronic properties (HOCO, LUCO, E{sub gap}, V{sub oc}, and V{sub bi}) are determined from 1D and 2D PBC to understand the effect of the number of rings in polythiophene. The absorption properties—excitation energies (E{sub ex}), the maximal absorption wavelength (λ{sub max}), oscillator strengths, and light harvesting—efficiency are studied using the time-dependent DFT method. Our studies show that changing the number of thiophene units can effectively modulate the electronic and optical properties. On the other hand, our work demonstrates the efficiency of theoretical calculation in the PBCs.

  11. Canada's global health role: supporting equity and global citizenship as a middle power.

    Canada's history of nation building, combined with its status as a so-called middle power in international affairs, has been translated into an approach to global health that is focused on equity and global citizenship. Canada has often aspired to be a socially progressive force abroad, using alliance building and collective action to exert influence beyond that expected from a country with moderate financial and military resources. Conversely, when Canada has primarily used economic self-interest to define its global role, the country's perceived leadership in global health has diminished. Current Prime Minister Justin Trudeau's Liberal federal government has signalled a return to progressive values, driven by appreciation for diversity, equality, and Canada's responsibility to be a good global citizen. However, poor coordination of efforts, limited funding, and the unaddressed legacy of Canada's colonisation of Indigenous peoples weaken the potential for Canadians to make meaningful contributions to improvement of global health equity. Amid increased nationalism and uncertainty towards multilateral commitments by some major powers in the world, the Canadian federal government has a clear opportunity to convert its commitments to equity and global citizenship into stronger leadership on the global stage. Such leadership will require the translation of aspirational messages about health equity and inclusion into concrete action at home and internationally. Copyright © 2018 Elsevier Ltd.

  12. The rise and fall of refineries

    International Nuclear Information System (INIS)

    Chretien, D.

    2002-01-01

    This paper described the rise and fall of refineries in Montreal. Well before Calgary, Montreal was the hub of activity for oil refineries because Montreal was the principle consuming market for petroleum products in Canada. The location was good, particularly since the soil was clay which helped prevent soil infiltration of petroleum. The first refinery in Montreal was constructed in 1916 by Esso, followed by Texaco in 1921 and Gulf in 1931. Initially oil was shipped by boat to the Port of Montreal from Saudi Arabia. Later, the petroleum came mostly from Venezuela. At the beginning of the 1980s many refineries were closed because they became obsolete and upgrading them would have been too costly. Only 3 refineries remain in Quebec, of which 2 are in Montreal. They are owned by Shell and PetroCanada. The third refinery in Quebec is in St-Romuald and is owned by UltraMar. One of the major contributing factors to the decline of the refining industry in Montreal was the decision in 1984 by former Prime Minister Trudeau to force Canadian provinces to purchase their petroleum from Alberta. This caused the petrochemical industry to locate in Sarnia in Ontario, leaving the Montreal refining centre to become obsolete. 3 figs

    Full Text Available En 1969, le gouvernement Trudeau publie son Livre blanc sur la politique indienne. Cet épisode marque le début d’un mouvement de mobilisation autochtone important qui s’organise autour du livre d’Harold Cardinal, The Unjust Society. Cet ouvrage a cependant éclipsé un autre discours nationaliste autochtone montant, celui des Métis, donnant la fausse impression qu’ils partageaient les mêmes préoccupations que les Premières nations. Le but de notre article est avant tout de mettre au jour le discours nationaliste métis de la fin des années 1960 et du début des années 1970 puisqu’il a été supplanté par le discours des Premières nations, mais aussi de démontrer en quoi il se distingue de ce dernier et où il se situe face à la question nationale canadienne.

Exercícios de ser criança (1999, primeiro livro do poeta Manoel de Barros publicado com a classificação infanto-juvenil, recupera as principais características do programa poético manoelino: a aversão ao utilitarismo da linguagem, o universo infantil como temática central, o devaneio como exercício poético. Assim, temas como brincadeiras, travessuras e o modo próprio de como a criança vive o devaneio são recorrentes em toda a obra. Neste sentido, busca-se compreender como Manoel de Barros, por meio de seu fazer poético, toma a infância como signo de eterno retorno a um tempo que, a priori, é irrecuperável, mas que através dos exercícios poéticos de ser criança, torna-se um espaço permanentemente imóvel, de recordação, de revisitação.

    The Lagoa Real Uranium Province located in the south-central part of the Bahia-BR, in the central portion of the San Francisco Craton, is composed of an association of Paleoproterozoic metagranitoids, alkali-gneisses, and albitites (barren and mineralized). Intense action of metamorphic and metasomatic processes characterize this region. These processes culminated in the transformation of granites into gneisses, albitites and U mineralization in some albitites bodies. There are three types of metagranites, Lagoa do Barro (1,77Ga), Juazerinho (1,75Ga) and São Timóteo (1,74Ga). In view of this information, we aimed to verify if the albite formed by metamorphism in the metagranites has the same fingerprint of the albite present in the barren albitites. We used a LA-ICP-MS system for this. The results allowed the determination of albites fingerprint, allowing the differentiation of at least two generations. The Sr / U ratio allows characterizing these generations. The albitites have albite with minimal microchemical variation. The metagranites Lagoa do Barro and São Timóteo has similar generation of albite. The Juazerinho presents two generations of albite, one with similar to São Timóteo, Lagoa do Barro and albitites and another generation with distinctly higher concentrations of Sr and U. These results show that the same event that generated the albitite's albite interfered with the formation of the metagranite's albite, but another event culminated with the formation of the second generation of the albite in the Juazerinho.

We employ a panel of 27 countries observed from 1820-2000 to explore whether regime types and institutional reforms have differential growth effects...... in monarchies and republics. A set of Barro-type regressions show that there are no significant growth differences between the two regime types and that the effects of incremental reforms do not differ between them, but that those of large-scale reforms do.

    Full Text Available This paper demonstrates oscillations in the economic growth model with endogenous population growth and physical and human capital accumulation proposed by Zhang (2014. This study generalizes Zhang’s model by treating all the time-independent parameters as time-dependent parameters. The model is a synthesis of the Solow growth model, Uzawa-Lucas two-sector model, and the Haavelmo population model and the Barro-Becker fertility choice model. The model studies the dynamic interdependence between population change, wealth accumulation, and human capital accumulation. We simulate the model to demonstrate existence of business cycles under different periodic shocks.

    Full Text Available A modification of Barro and Sala-i-Martin empirical framework of growth model is specified to examine determinants of per capita growth in 74 Russian regions during period of 1996-2005. We utilize both panel and cross-sectional data. Results imply that in general regional growth in 1996-2005 is explained by the initial level of region's economic development, the 1998 financial crisis, domestic investments, and exports. Growth convergence between poor and rich regions in Russia was not found for the period studied.

    Full Text Available Se rebaten dos tipos de críticas sobre Cuentos de barro (1933, de Salarrué: se cuestionan interpretaciones que identifican a los personajes con los indígenas y los negros reales de El Salvador en las décadas de 1920 y 1930; por otra parte, se disputan las críticas académicas que, a pesar de reconocer el ingrediente inventivo en las representaciones de los personajes, califican la ficción de un acto engañoso. Con el análisis de «El negro», con atención en el discurso metafórico, el realismo de Salarrué es más complejo que el realismo concebido como una copia fiel del mundo real. The study refutes two types of criticism about Cuentos de barro (1933, by Salarrué. It questions interpretations identifying the characters with real indigenous and black people in El Salvador in the 1920s and 1930s. Moreover, it argues against academic criticism which, in spite of acknowledging the non-realistic traits of the characters, describes the fiction as misleading. Through the analysis of “El negro”, with attention to the metaphoric discourse, Salarrué’s realism is viewed as more complex than realism conceived of as a faithful copy of the real world.

    2015-04-01

    Upscaled (effective) dispersion coefficients in spatially heterogeneous flow fields must (1) account for the sub-scale variability that is filtered out by homogenization and (2) be modeled as a random function to incorporate the uncertainty associated with non-ergodic solute bodies. In this study, we use the framework developed in de Barros and Rubin (2011) [de Barros F.P.J. and Rubin Y., Modelling of block-scale macrodispersion as a random function. Journal of Fluid Mechanics 676 (2011): 514-545] to develop novel semi-analytical expressions for the first two statistical moments of the block-effective dispersion coefficients in three-dimensional spatially random flow fields as a function of the key characteristic length scales defining the transport problem. The derived expressions are based on perturbation theory and limited to weak-to-mild heterogeneity and uniform-in-the-mean steady state flow fields. The semi-analytical solutions provide physical insights of the main controlling factors influencing the temporal scaling of the dispersion coefficient of the solute body and its self-averaging dispersion behavior. Our results illustrate the relevance of the joint influence of the block-scale and local-scale dispersion in diminishing the macrodispersion variance under non-ergodic conditions. The impact of the statistical anisotropy ratio in the block-effective macrodispersion self-averaging behavior is also investigated. The analysis performed in this work has implications in numerical modeling and grid design.

    This research is an examination of the relationship between loneliness and a number of psychosocial variables (e.g., affective state, cultural issues, gender, age) among adolescents and young adults from Cape Verde and Portugal. Two studies are presented. The participants in the first study were 285 adolescents from Cape Verde and 202 from Portugal, and in the second study there were 134 college students from Cape Verde and 112 from Portugal. The following instruments were administered to all the participants in both studies: The Revised UCLA Loneliness Scale (D. Russell, L. Peplau, & C. Cutrona, 1980), the Neuroticism Scale (J. Barros, 1999), the Optimism Scale (J. Barros, 1998), the Social Anxiety subscale (A. Fenigstein, M. Scheier, & A. Buss, 1975), and the Satisfaction With Life Scale (E. Diener, R. Emmons, R. Larsen, & S. Griffin, 1985). No ethnic or gender differences were found for loneliness between the two groups. For both groups, the most prominent predictors of loneliness were neuroticism and dissatisfaction with life. However, as expected, the adolescent group recorded higher scores for loneliness than did the college students.

    1 - Description of program or function: The SMACS (Seismic Methodology Analysis Chain with Statistics) system of computer programs is one of the major computational tools of the U.S. NRC Seismic Safety Margins Research Program (SSMRP). SMACS is comprised of the core program SMAX, which performs the SSI response analyses, five pre- processing programs, and two post-processors. The pre-processing programs include: GLAY and CLAN, which generate the nominal impedance matrices and wave scattering vectors for surface-founded structures; INSSIN, which projects the dynamic properties of structures to the foundation in the form of modal participation factors and mass matrices; SAPPAC, which projects the dynamic and pseudo-static properties of multiply-supported piping systems to the support locations, and LNGEN, which can be used to generate the multiplication factors to be applied to the nominal soil, structural, and subsystem properties for each of the response calculations in accounting for random variations of these properties. The post-processors are: PRESTO, which performs statistical operations on the raw data from the response vectors that SMAX produces to calculate best fit lognormal distributions for each response location, and CHANGO, which manipulates the data produced by PRESTO to produce other results of interest to the user. Also included is the computer program SAP4 (a modified version of the University of California, Berkeley SAPIV program), a general linear structural analysis program used for eigenvalue extractions and pseudo-static mode calculations of the models of major structures and subsystems. SAP4 is used to prepare input to the INSSIN and SAPPAC preprocessing programs. The GLAY and CLAN programs were originally developed by J.E. Luco (UCSD) and H.L. Wong (USC). 2 - Method of solution: SMACS performs repeated deterministic analyses, each analysis simulating an earthquake occurrence. Uncertainty is accounted for by performing many such analyses

    A thermal analysis of the envelope of one of the most used housing models for low income groups, as those offered by the Mexican Government is presented in this report. The building's thermal gain in walls was determined, using: concrete block, brick and adobe; and considering concrete of roofing, concrete floors, windows and doors equal in all the cases. The objective of this study is to know the contribution to the building's thermal load of each one of the materials applied. The calculation was conducted using the Doe 2.1E thermal simulator software, using meteorological data for the city of El Centro, California, USA. This was so, because there is no reliable weather data for the city of Mexicali, B.C., where the housing units are. Because of geographical proximity between of these cities the same data was used. The properties for each one of the three building materials were taken from specialized bibliography. It was determined that the housing built with adobe walls has thermal advantages over the units built with concrete block and brick. The adobe unit has a lower thermal load of 13% over the concrete block, and of 3.44% over the clay brick unit.

    Full Text Available Aggregates (gravel and sand are, after water, the Earth’s second most used natural resource, representing about 50% of all consumed mineral resources. Aggregate production generates a large quantity of waste from the aggregate washing process. This waste is made up of suspended solids – sludge – which has a great environmental impact. It is deposited in huge troughs because of the impossibility of discharging it directly into rivers. Many plants have incorporated decanters and filter presses to separate the solid from the liquid fraction. This paper evaluates the possibility of exploiting the solid fraction (i.e. sludge in the manufacture of fired clay bricks. The added value of these bricks is, on the one hand, the exploitation of sludge as a currently useless waste product, and on the other, the use of this sludge to enhance the physical and mechanical properties of conventional fired clay bricks.Los áridos son la segunda materia prima más consumida en la Tierra después del agua, representando alrededor del 50% de todos los recursos minerales consumidos. El proceso de elaboración de estos áridos genera una gran cantidad de residuos procedentes de su lavado. Se trata de partículas sólidas en suspensión – lodos – de gran impacto ambiental, que se depositan en grandes charcas ante la imposibilidad de verterlos directamente al rio. Muchas empresas han incorporado decantadores y filtros de prensa para separar la fracción solida de la líquida. El presente trabajo evalúa la posibilidad de utilizar la fracción sólida, es decir el barro, para la fabricación de piezas cerámicas. El valor añadido de estas piezas es por un lado el aprovechamiento del barro como producto residual, que en estos momentos es desechable, y por otro, conseguir que este barro mejore las propiedades físico-mecánicas de la cerámica convencional.

    Large tropical canopy trees contain the majority of forest biomass in addition to being the primary producers in the forest ecosystem in terms of both food and structural habitat. The spatial distributions of large tropical trees are non-randomly distributed across environmental gradients in light, water and nutrients. These environmental gradients are a result of the biophysical processes related to topography and three-dimensional forest structure. In this study we examine large (>10 cm) diameter tree species richness across Barro Colorado Nature Monument in a tropical moist forest in Panama using active and passive remote sensing. Airborne light detection and ranging and high-resolution satellite imagery were used to quantify spectral heterogeneity, sub-canopy topography and vertical canopy structure across existing vegetation plots to model the extent to which remote sensing variables can be used to explain variation in large tree species richness. Plant species richness data was calculated from the stem mapped 50-ha forest dynamics plot on Barro Colorado Island in addition to 8 large tree plots across the Barro Colorado Nature Monument at 1.0 ha and 0.25 ha spatial scales. We investigated four statistical models to predict large tree species richness including spectral, topographic, vertical canopy structure and a combined ';global' model which includes all remote sensing derived variables. The models demonstrate that remote sensing derived variables can capture a significant fraction (R2= 0.54 and 0.36) of observed variation in tree species richness across the 1.0 and 0.25 ha spatial scales respectively.

  20. Fur rubbing behavior in free-ranging black-handed spider monkeys (Ateles geoffroyi) in Panama.

    Campbell, C J

    2000-07-01

    Members of the population of black-handed spider monkeys (Ateles geoffroyi) on Barro Colorado Island, Panama, use the leaves of three Rutaceae species in a behavior that resembles fur rubbing in the white faced capuchin (Cebus capucinus). This behavior has not been reported from other sites where Ateles has been studied. During more than 1,200 hours of observation, 30 episodes of this behavior were recorded ad libitum. Adult males engage in this behavior more than adult females. Season did not impact the frequency of the behavior. The behavior described here differs in many respects from that reported for Cebus capucinus, and does not fit the hypotheses that the behavior functions in repelling insects or other antiseptic purposes. It is proposed that fur rubbing in this group of spider monkeys is a modification of a behavior previously recorded in Ateles and may function in scent marking.

    I report ad libitum data on 18 copulations involving free-ranging black-handed spider monkeys (Ateles geoffroyi) on Barro Colorado Island, Panama. All copulations were performed in a dorsoventral position, as is typically reported for this genus. Intromission often appeared difficult to achieve, possibly as a result of the large size of the glans penis in these animals. The average length from intromission to termination of thrusting exceeded 17 min, followed by an average period of almost 2 min before separation occurred, which suggests the possibility of a copulatory lock. Offspring of the female participant were almost always in close proximity to or in contact with the pair, and harassment by the offspring was observed only during the final stages of the copulation. All but one copulatory event occurred in complete seclusion from other adult males, and sexual behavior was not limited to any one adult male in the group. 2006 Wiley-Liss, Inc.

    I report three cases of coalitionary aggression by adult male black-handed spider monkeys (Ateles geoffroyi) against subadult males within their community on Barro Colorado Island (BCI), Panama. Two of these cases were followed by the disappearance and presumed death of the victim. Similar behavior was recently reported by Valero et al. [in press], who suggested that this behavior may be the result of intense male reproductive competition. Like the single instance they reported, the cases I report all occurred when the operational sex ratio was approximately 1:1, which suggests that intense competition among males for access to reproductively viable females may be a contributing factor. Additionally the very low density of spider monkeys on BCI may play a significant role in the occurrence of this lethal aggression. Large numbers of adult males are not necessary to protect a territorial boundary against neighboring groups, and additional males may act merely as mating competition. (c) 2006 Wiley-Liss, Inc.

    We propose a simple and powerful method for determining the transition process in continuous-time DSGE models under Poisson uncertainty numerically. The idea is to transform the system of stochastic differential equations into a system of functional differential equations of the retarded type. We...... then use the Waveform Relaxation algorithm to provide a guess of the policy function and solve the resulting system of ordinary differential equations by standard methods and fix-point iteration. Analytical solutions are provided as a benchmark from which our numerical method can be used to explore broader...... classes of models. We illustrate the algorithm simulating both the stochastic neoclassical growth model and the Lucas model under Poisson uncertainty which is motivated by the Barro-Rietz rare disaster hypothesis. We find that, even for non-linear policy functions, the maximum (absolute) error is very...

    Sphenodontians were a successful group of rhynchocephalian reptiles that dominated the fossil record of Lepidosauria during the Triassic and Jurassic. Although evidence of extinction is seen at the end of the Laurasian Early Cretaceous, they appeared to remain numerically abundant in South America until the end of the period. Most of the known Late Cretaceous record in South America is composed of opisthodontians, the herbivorous branch of Sphenodontia, whose oldest members were until recently reported to be from the Kimmeridgian–Tithonian (Late Jurassic). Here, we report a new sphenodontian, Sphenotitan leyesi gen. et sp. nov., collected from the Upper Triassic Quebrada del Barro Formation of northwestern Argentina. Phylogenetic analysis identifies Sphenotitan as a basal member of Opisthodontia, extending the known record of opisthodontians and the origin of herbivory in this group by 50 Myr. PMID:24132307

    Full Text Available This paper analyses the classic map of hereditary captaincies of Portuguese America when it was created, in the first half of the sixteenth century. We point out some of its shortcom - ings, and propose a new design on primary sources, namely: charts of donation and forais, as well as the cartography of the time, particularly the map of Bartolomeu Velho. The main changes proposed refer to: boundary lines of the northern captaincies, which should follow the meridians and not the parallels; the particular configuration of the southern captaincies, with lines following northwest direction; the division into portions, named quinhões, of the captaincies of Aires da Cunha and Joao de Barros and finally the existence of undistributed lands.

    Full Text Available The neoclassical growth models argued that the movement to steady states; technology, exogenous rate of savings, population growth and technical progress stimulate higher growth levels (Solow 1956. Contrary to the neoclassical argument, endogenous growth model argues that, in the theory of endogenous growth, government play a significant role in promoting accumulation of knowledge, research and development, public investment, human capital development, law and order can generate growth both in the short and long run. Moreover, they assumed technical progress as endogenous variable for growth (Barro 1995. This study analyze the effects of fiscal deficit on sustainability of economic growth and provided new empirical evidence on the effects of fiscal deficit on saving and sustainability of economic growth based on the assumption of endogenous growth model. We estimated using the reduced form of GMM method for dynamic panels covers 1990-2009 for three emerging countries that includes China, India and South Africa.

    The Chilean President José Manuel Balmaceda (1886-1891) had a constitutional conflict with the parliament. This conflict lead to a revolution that ended with the President's suicide, when he was refuged at the Argentinian Embassy in September 1891. President Balmaceda conducted an authoritarian government during several months. A decree from February, 1897, disposed the reorganization of the Medical School, dismissed and imprisoned the Dean, Dr Barros-Borgoño and nominated new Professors. Dr Nicanor Rojas, Professor of Gynecology was assigned as Dean and Dr Carlos Sazié as secretary. During the During the war against Perú and Bolivia, Dr. Rojas worked gratuitously and became prominent, being named Chief Surgeon of the Chilean Army. After the triumph of the revolution against President Balmaceda, Dr Rojas was discharged, and died in 1892.

    Full Text Available Hematological results are reported for 13 giant anteaters (Myrmecophaga tridactyla and 13 collared anteaters (Tamandua tetradactyla. Animals were captive-reared adults held at the Fundação Parque Zoológico de São Paulo (São Paulo, SP, Brazil and Parque Zoológico Municipal Quinzinho de Barros (Sorocaba, SP, Brazil, and were considered healthy on physical examination. Examined parameters included red blood cell count, white blood cell count, hematocrit, hemoglobin concentration, mean corpuscular volume, mean corpuscular hemoglobin, mean corpuscular hemoglobin concentration, total plasmatic protein and differential leukocyte counts. Also, a survey for hemoparasites was done and none was observed in thin blood smears. The results were generally similar to those previously reported in the exiguous literature for these species, providing further reference data for the interpretation of laboratory results besides health monitoring, assisting early disease diagnosis and providing relevant information for conservation programs for these species.

    1984-01-01

    The main objective of the project was the geological and seismological characterization of 230 Km 2 along the coastal region between the Barro Branco and Jureia massifs in order to pinpoint one or more local areas showing adequate geological, morphological and geotechnical conditions suitable for construction of nuclear power plants. Results of the investigations, as well as the methodology used for determination of main interesting areas are presented. The best areas for construction are believed to be situated along the coast where Precambrian basement rocks crop out close to the shoreline. The Tertiary-Quaternary sedimentary cover reaches a thickness of 50 or more meters and the character of the sediments does not allow direct emplacement of foundations for heavy-weight constructions. Historical analysis of seismic activity of the region, as well as the study of faults and fracture zones identified in the area demonstrate the absence of active faults such as defined by internationally accepted safety criteria.

The work appears as one way in which the subject reaches appreciation in the capitalist social formation. According to Orlandi (2007, p. 15, this social formation of "heroic culture of the subject" works coercively and makes him responsible for the success or failure of his endeavors. That way, in addition to corroborate to a social frame of medicalization (BARROS, 2004, there are different directions in the production of meanings about depressive symptoms.

    In some areas in Brazil the great distance of the generating and consuming centers, together with the low consumption of electric energy of these areas, they make unfeasible investments with transmission and distribution. The use of the biomass as fuel in the distributed generation, is low pollutions, it is renewable, besides possessing a low cost when compared to the fossil fuels [Barros, 2003]. By the way the generation distributed through renewable fuels, becomes an attractive solution for generation in distant and isolated areas of the electric system. Inside of this context, this paper proposes the use of a module combustor, biomass-motor Stirling, based on induction generator, applied to isolated areas, such as the north and northeast areas of the Brazil.

    Full Text Available The article is devoted to evaluating β-convergence of the socio-economic development of Ukraine’s regions. The essence and theoretical basis of evaluation of σ- and β-convergence is studied. The neoclassical theory of growth of R. Solow that serves as a basis for models of β-convergence is considered. The essence and features of evaluation of the absolute (unconditional and conditional β-convergence is examined. The existing empirical researches of the economic development of countries and their regions with the use of convergence models are analyzed and it is found that: the theory of convergent-divergent development of countries and their regions is sufficiently developed; there are certain studies aimed at evaluation and analysis of the convergence of regional development in Ukraine, but there is no comprehensive study that comprises the building of all the above types of β-convergence models for the period covering the years before and after the crisis of 2008–2009. A scheme of the investigation of the convergence process in regions of Ukraine is proposed, and on this basis the evaluation of β-convergence for Ukraine’s regions is conducted with the use of four types of models: the Barro and Sala-i-Martin model, the Baumol model, the Solow-Swan model, the Cuadrado-Roura model. On the basis of the study it has been found that for the peripheral regions the presence of convergence of their social and economic development is determined by the share of services in the gross regional product to a greater extent and availability of mineral resources to a less extent, but the given result is obtained only with the use of the Barro Sala-i-Martin model, for the other models the condition of β-convergence is not met.

Este es el primer estudio que documenta los niveles de plomo en sangre en población infantil de Morelos, México, y sus resultados son punto de partida para acciones futuras de control y prevención.

  11. Dark Earths and manioc cultivation in Central Amazonia: a window on pre-Columbian agricultural systems?

    Directory of Open Access Journals (Sweden)

    James A. Fraser

    Full Text Available Many commentators highlight the fertility of Anthropogenic Dark Earths (ADE, emphasizing their potential for sustainable agriculture. Some scholars believe that terra mulata (the less fertile, more extensive form of ADE was created by means of agricultural practices used by large settled populations of pre-Columbian farmers. But what was it that these Amerindian farmers were growing? Until recently, scholarly consensus held that manioc does not perform well on ADE. New research on the middle Madeira River is showing, however, that this consensus was premature. In this region, the most common crop in ADE fields is bitter manioc. Farmers there have various landraces of manioc that they believe yield particularly well on ADE, and logically plant more of these varieties on ADE. Aspects of the behaviour and perception of manioc cultivation among 52 farmers at the community of Barro Alto were measured quantitatively on four terra firme soil types (Terra Preta, Terra Mulata, Oxisols and Ultisols. These farmers plant different configurations of landraces in different soils, according to their perception of the suitability of particular landraces and their characteristics to certain soil types and successional processes. This, in turn, shapes selective pressures on these varieties, as new genetic material incorporated from volunteer seedlings is more likely to contain traits present in the most prevalent landrace(s in each soil type. Owing to localized population pressure at Barro Alto, manioc is under more intensive cultivation systems, with shorter cropping periods (5-10 months and shorter fallow periods (1-2 years. The outcome of these processes is different co-evolutionary dynamics on ADE as opposed to non-anthropogenic soils. Further anthropological study of manioc swiddening in one of the richest agricultural environments in Amazonia can fill a gap in the literature, thus opening an additional window on the pre-Columbian period.

These farmers plant different configurations of landraces in different soils, according to their perception of the suitability of particular landraces and their characteristics to certain soil types and successional processes.This, in turn, shapes selective pressures on these varieties, as new genetic material incorporated from volunteer seedlings is more likely to contain traits present in the most prevalent landrace(s in each soil type. Owing to localized population pressure at Barro Alto, manioc is under more intensive cultivation systems, with shorter cropping periods (5-10 months and shorter fallow periods (1-2 years. The outcome of these processes is different co-evolutionary dynamics on ADE as opposed to non-anthropogenic soils. Further anthropological study of manioc swiddening in one of the richest agricultural environments in Amazonia can fill a gap in the literature, thus opening an additional window on the pre-Columbian period.

    Depression is one of the major contributors to the global burden of diseases; however, population-based data in South America are limited. We conducted a population-based cross sectional study with 7524 participants, aged 35-74 years old, recruited between February 2010 and December 2011 from randomly selected samples in 4 cities (Bariloche and Marcos Paz, Argentina; Temuco, Chile; and Pando-Barros Blancos, Uruguay). Major Depressive Episode (MDE) was assessed using the Patient Health Questionnaire (PHQ) - 9. The overall prevalence of MDE was 14.6% (95% CI: 13.6, 15.6). However, there was a geographical variability of up to 3.7 folds between different cities being 5.6% (95% CI: 4.6, 6.7) in Marcos Paz, Argentina; 9.5% (95% CI: 8.2, 10.9) in Bariloche, Argentina; 18.1% (95% CI: 16.3, 20.0) in Temuco, Chile, and 18.2 (95% CI: 16.3, 20.2) in Pando-Barros Blancos, Uruguay. The multivariate model showed that, adjusted by location, being female, being between 35 and 44 years old, having experienced at least one stressful life event, currently smoking, and having a history of chronic medical diseases were independently associated with an increased risk of MDE, while having higher education and being married or living with a partner reduced the risk of MDE. These results are representative of the selected cities included in the study. As such extrapolation to the general populations of Argentina, Chile, and Uruguay should be done with caution CONCLUSIONS: This study showed a high prevalence and variability of MDE in the Southern Cone of Latin America.

    Full text: Virotec Global Solutions has announced what it believes is the first successful destruction of intractable organochlorine pesticide contamination in industrial wastewater. Dichlorodiphenyltrichloroethane, otherwise known as DDT, is one of the most intractable and persistent chemical compounds known to man. In February remediation specialist Virotec reported it had been successful in reducing DDT contaminant levels. In addition to destroying DDT in wastewater, Virotec showed its ViroFlow Technology can reduce levels of two DDT metabolites (or breakdown products), DDD and DDE, along with an organo-phosphate insecticide called chlorpyrifos. Virotec was commissioned by a large pesticide and fertiliser company to find a way of using its ViroFlow suite of products to reliably reduce high levels of pesticides and heavy metals from wastewater and stormwater at an industrial site. “Along with our strategic partner Green Shadows Commercial from Tasmania, we were able to successfully reduce DDT from 108 parts per billion to under two parts per billion in industrial wastewater using a combination of ozofractionation and ElectroBind reagent,” said business development manager Gisela Barros. “In addition, we were successful in demonstrating similar reductions in Dichlorodiphenyldichloroethane (DDD) from 15.2 parts per billion to under 0.5 parts per billion, and Dichlorodiphenyldichloroethylene (DDE) from one part per billion to under accurate to around 0.5 parts per billion.” The level of detection for pesticides was 0.5 parts per billion (ppb). In addition, ViroFlow reduced chlorpyrifos from 7,972 ppb to 6.4 ppb, arsenic (a key ingredient in pesticide composition) from 0.13 parts per million (ppm) to 0.002 ppm, and zinc from 0.35 ppm to less than 0.005 ppm. “The significance of these findings cannot be overstated,” Barros said. “DDT and its metabolites are among the most persistent and toxic contaminants to be found in soil and groundwater and

The heated lidocaine/tetracaine (HLT patch has been reported to reduce SIS pain in a small case series. Methods: This was a prospective, randomized, open-label clinical trial in which adult patients with SIS pain lasting at least 14 days, with an average intensity of ≥4 on a 0–10 scale (0= no pain, 10= worst pain were randomized to treatment with the HLT patch or a single subacromial injection of triamcinolone acetonide (10 mg. Patients in the HLT patch group applied a single HLT patch to the shoulder for 4 hours twice daily, with a 12-hour interval between treatments during the first 14 days, and could continue to use the patch on an as-needed basis (up to twice daily during the second 14-day period. No treatment was allowed in the final 14-day period. At baseline and at days 14, 28, and 42, patients rated their pain and pain interference with specific activities (0–10 scale. Results: Sixty patients enrolled in the study (average age =51 years, range 18–75, n=21 female. Average pain scores declined from 6.0±1.6 at baseline to 3.5±2.4 at day 42 in the HLT patch group (n=29, P<0.001 and from 5.6±1.2 to 3.2±2.6 in the injection group (n=31, P<0.001. Similar improvements were seen in each group for worst pain; pain interference with general activity, work, or sleep; and range of motion. No significant between-group differences were seen for any pain or pain interference scores at any time point. Conclusion: These results suggest that short-term, noninvasive treatment

  18. Immigration in two federations: Canada and Australia.

    The need for increasingly widespread application of a policy or program, settlement, and multiculturalism is urgent in both Canada and Australia. For both countries there is a clear pattern of coalescence and divergence and the distinct growth of immigration as a federal function. While Australia has strengthened federal functions in a area of increasingly geo-political need, Canada is moving towards a looser model of federalism. By 1918 both countries were strengthening their federal functions in immigration as discussions within the British Empire on the recommendations of the 1917 Dominions Royal Commission took root. Both countries were interested in agricultural immigration and land settlement. The Great Depression caused a major reduction in population growth rates. From 1933-1948 Canada had a poor record of providing sanctuary for Jews. In Australia, however, Jewish voluntary agencies were aiding the reception of refugees by 1937. The 1st permanent embodiment of commonwealth jurisdiction over immigration was the establishment of an Immigration Branch within the Department of Interior around 1938. Australia needed extra population for defense. The major structural link between government and the immigrant communities was through the Good Neighbor Movement, which began on a nationwide basis in 1950. Both Canada and Australia are major receiving countries for refugees. In 1973 Australia reached the position of effective, practical nondiscrimination achieved by Canada in 1967. Prime Minister Trudeau's policy was multiculturalism within a framework of bilingualism. By 1978 Australia had a new federalism policy, which in all areas concerned with immigrants, refugees and ethnicity, rationalized resources allocation and imposed a political philosophy. The foci of multiculturalism in Australia are 1) community languages; 2) creation of a tolerant, non-discriminatory society; and 3) equity and participation. In 1978 Australia specified population replacement and

There are conflicting results for the association of the CD14 C-159T SNP with total serum immunoglobulin E (IgE levels and atopy. There are limited data regarding the association of the CD14 C-159T SNP in subjects of African ancestry. The aim of the study was to determine whether the C-159T SNP and other CD14 SNPs (C1188G, C1341T were associated with total serum IgE levels and with allergy skin test results in nonatopic and atopic subjects; as well as in Caucasian and African American subjects.Methods: A total of 291 participants, 18–40 years old, were screened to determine whether they were atopic and/or asthmatic. Analyses were performed to determine the association between CD14 C-159T, C1188G, or C1341T genotypes with serum IgE levels and with the number of positive skin tests among Caucasian or African American subjects.Results: We found no significant association of serum total IgE level with CD14 C-159T, C1188G, or C1341T genotypes within nonatopic or atopic subjects. Subjects with CD14-159 T alleles had significantly more positive allergen skin tests than subjects without CD14-159 T alleles (P = 0.0388. There was a significant association between the CD14 1188 G allele, but not the CD14 1341 T allele, with the number of positive skin-test results in Caucasians, but not in African Americans.Conclusion: These results support a possible association between CD14 polymorphisms and atopy.

We hope that national libraries and other heritage institutions will find our model useful as they consider how to capture, preserve, and analyze ongoing events using Twitter. While Twitter is not a representative sample of broader society - Pew research shows in their study of US users that it skews young, college-educated, and affluent (above $50,000 household income – Twitter still represents an exponential increase in the amount of information generated, retained, and preserved from 'everyday' people. Therefore, when historians study the 2015 federal election, Twitter will be a prime source.On August 3, 2015, the team initiated both a Search API and Stream API collection with twarc, a tool developed by Ed Summers, using the hashtag #elxn42. The hashtag referred to the election being Canada's 42nd general federal election (hence 'election 42' or elxn42. Data collection ceased on November 5, 2015, the day after Justin Trudeau was sworn in as the 42nd Prime Minister of Canada. We collected for a total of 102 days, 13 hours and 50 minutes. To analyze the data set, we took advantage of a number of command line tools, utilities that are available within twarc, twarc-report, and jq. In accordance with the Twitter Developer Agreement & Policy, and after ethical deliberations discussed below, we made the tweet IDs and other derivative data available in a data repository. This allows other people to use our dataset, cite our dataset, and enhance their own research projects by drawing on #elxn42 tweets.

  1. 2016 Status Report on Major Equipment Procurement

    Full Text Available The Department of National Defence made some progress in procurement in 2016 despite obstacles that included a continued drop in spending, the advent of a new federal Liberal government and uncertainty over the outcome of the Defence Policy Review. Four trends affected defence acquisitions in 2016. These include an ongoing slippage in recapitalizing the Canadian Armed Forces, some encouraging moves made on the shipbuilding and fighter jet files, mixed progress on implementing the 2014 Defence Procurement Strategy, and uncertainty over the Defence Policy Review. It is also too early to tell how the Trudeau government’s Policy on Results, known as the “deliverology” approach, will play out for defence procurement. However, Budget 2016’s major focus was not on defence, and it shifted some funding for capital equipment to a new endpoint of 2045. This suggests that delay in the overall defence procurement program continues. While the Liberals kept their pledge to make investment in the Royal Canadian Navy a priority, they also made good last year on a negative promise – not to purchase the F-35 stealth fighter bomber. However, further slowing things is the Liberals’ refusal to launch a competition to replace it until the Defence Policy Review is published. The government has made this situation more fraught with its intention to buy 18 Boeing Super Hornet fighter jets as interim aircraft, since Liberal policy requires the Royal Canadian Air Force to be capable of meeting both NORAD’s and NATO’s operational needs simultaneously. Prior to the release of the new defence policy, both the interim and permanent fighter aircraft projects lacked adequate funding. They were among several large projects that have been approved, but have not yet moved to the contract stage, and whose budgets were inadequate to move forward. Adding to this mix is the fact that a government-wide effort initiated in 2014 to streamline the defence procurement

    Full Text Available Alumina based ceramic materials, containing Al-rich sludge as the major component, were processed by extrusion. The sludge derived from the wastewater treatment of aluminium anodising industrial process. Long rods were produced using a vacuum screw extruder, by a careful control of all relevant processing parameters. Then, thick discs were obtained by cutting dried selected rods, to be tested as probes for sintering-dependent electrical properties. The sintering process was followed by performing common dilatometric/thermal analyses but the evolution of electrical conductivity, estimated by impedance spectroscopy (IS, was also used for this purpose. Results show that sintering-dependent morphological evolution up to 1300ºC strongly affects the electrical behaviour of samples, and as a consequence IS seems to be a useful technique to follow the firing process.

    Los materiales cerámicos basados en alúmina, conteniendo barros ricos en Al como componente mayoritario fueron procesados por extrusión. Los barros empleados provienen de tratamientos de lavado de residuos de un proceso industrial de anodizado de aluminio. Se produjeron varillas empleando un extrusor de tornillo en vacío con control de todos los parámetros relevantes del proceso. A partir de varillas seleccionadas, se obtuvieron por corte en seco discos cerámicos para evaluar la dependencia de la sinterización y las propiedades eléctricas. El proceso de sinterización se siguió mediante ensayos dilatométricos y análisis térmicos, junto con la evolución de la conductividad eléctrica mediante espectroscopia de impedancia. Los resultados mostraron la evolución de la sinterización y la dependencia morfológica hasta 1300ºC, que afecta fuertemente a la respuesta eléctrica y como consecuencia la espectroscopia de impedancia parece ser una técnica útil en el seguimiento de los procesos de cocción.

    Full Text Available Objetivamos verificar como características socioculturais e familiares influenciam na adaptação escolar de crianças guarani-kaiowá dos municípios Dourados e Caarapó, kadiwéu, da aldeia Alves de Barros na Bodoquena e terena de Córrego do Meio, município de Sidrolândia, em Mato Grosso do Sul, Brasil. Foram realizadas entrevistas e observações de crianças e pais dos referidos grupos. Observamos o diálogo e respeito mútuo na relação entre pais e filhos, evidenciado no tom sereno e suave com o qual as mães dirigem-se aos filhos. A curiosidade infantil não é reprimida, permitindo a exploração do ambiente, a participação em todas as atividades familiares, sem restrição, punição ou castigo. Porém no grupo terena, as mães conversam com as crianças, mas na segunda vez que elas desobedecem, levam palmadas ou "varinhadas" com vara verde, o que aponta para um exemplo de como a cultura vem se transformando pelo fácil acesso e contato com a sociedade nacional.The aim of this research was to verify how social-cultural and family characteristics influence in the adaptation of Indian children at school. The observed ethnic groups were the Guarani-Kaiowá (Caarapó and Dourados municipalities, the Kadiwéu (Alves de Barros and Terena (Córrego do Meio, MS, Brazil. Interviews and observations were performed in those children and their parents. It was observed the dialog and the mutual respect in the relations, evidenced in a serene tone with which mothers addressed to their children. Children's curiosity is not repressed, as well as the participation in all of the family's activities without restriction or punishment. However, in the Terena's group, mothers at first talk to their children, and at second if they disobey again, they get slaps or get bitten by sticks. That behavior points out to an example of how culture is changing by the easy access with the national society.

    There is an increasing interest in identifying theories, empirical data sets, and remote-sensing metrics that can quantify tropical forest alpha diversity at a landscape scale. Quantifying patterns of tree species richness in the field is time consuming, especially in regions with over 100 tree species/ha. We examine species richness in a 50-ha plot in Barro Colorado Island in Panama and test if biophysical measurements of canopy reflectance from high-resolution satellite imagery and detailed vertical forest structure and topography from light detection and ranging (lidar) are associated with species richness across four tree size classes (>1, 1-10, >10, and >20 cm dbh) and three spatial scales (1, 0.25, and 0.04 ha). We use the 2010 tree inventory, including 204,757 individuals belonging to 301 species of freestanding woody plants or 166 ± 1.5 species/ha (mean ± SE), to compare with remote-sensing data. All remote-sensing metrics became less correlated with species richness as spatial resolution decreased from 1.0 ha to 0.04 ha and tree size increased from 1 cm to 20 cm dbh. When all stems with dbh > 1 cm in 1-ha plots were compared to remote-sensing metrics, standard deviation in canopy reflectance explained 13% of the variance in species richness. The standard deviations of canopy height and the topographic wetness index (TWI) derived from lidar were the best metrics to explain the spatial variance in species richness (15% and 24%, respectively). Using multiple regression models, we made predictions of species richness across Barro Colorado Island (BCI) at the 1-ha spatial scale for different tree size classes. We predicted variation in tree species richness among all plants (adjusted r² = 0.35) and trees with dbh > 10 cm (adjusted r² = 0.25). However, the best model results were for understory trees and shrubs (dbh 1-10 cm) (adjusted r² = 0.52) that comprise the majority of species richness in tropical forests. Our results indicate that high

    Full Text Available En el decenio de los 2000 la desigualdad del ingreso en la América Latina se redujo. Este artículo aplica una variante de la metodología de descomposición no paramétrica propuesta por Barros et al (2006, 2007 para evaluar la importancia de las fuentes de ingreso de los hogares, en particular la aportación de las transferencias públicas, en los cambios en la desigualdad de ingresos en los años 2000 en los países del Cono Sur: Argentina, Brasil, Chile y Uruguay. Los resultados sugieren que los ingresos no laborales tuvieron una contribución significativa en los cambios en la desigualdad y que este efecto fue explicado principalmente por la consecuencia igualadora que tuvieron las fuentes públicas en los cuatro países analizados. La dinámica de los cambios en esta fuente de ingreso y su efecto en la desigualdad estuvo fuertemente asociada con la instrumentación o expansión de programas de transferencia no contributivos en el pasado decenio.

    Three Microwave Radiometers (two 3-channel and one 2-channel) were deployed in the Southern Appalachian Mountains in western North Carolina as part of the Integrated Precipitation and Hydrology Experiment (IPHEx), which was the first National Aeronautics and Space Administration (NASA) Global Precipitation Mission (GPM) Ground Validation (GV) field campaign after the launch of the GPM Core Satellite (Barros et al. 2014). The radiometers were used along with other instrumentation to estimate the liquid water content of low-level clouds and fog. Specifically, data from the radiometers were collected to help, with other instrumentation, to characterize fog formation, evolution, and dissipation in the region (by monitoring the liquid water path in the column) and observe the effect of that fog on the precipitation regime. Data were collected at three locations in the Southern Appalachians, specifically western North Carolina: a valley in the inner mountain region, a valley in the open mountain pass region, and a ridge in the inner region. This project contributes to the U.S. Department of Energy (DOE)’s Atmospheric Radiation Measurement (ARM) Climate Research Facility mission by providing in situ observations designed to improve the understanding of clouds and precipitation processes in complex terrain. The end goal is to use this improved understanding of physical processes to improve remote-sensing algorithms and representations of orographic precipitation microphysics in climate and earth system models.

    Climate change threatens biodiversity worldwide, however predicting how particular species will respond is difficult because climate varies spatially, complex factors regulate population abundance, and species vary in their susceptibility to climate change. Studies need to incorporate these factors with long-term data in order to link climate change to population abundance. We used 40 years of lizard abundance data and local climate data from Barro Colorado Island to ask how climate, total lizard abundance and cohort-specific abundance have changed over time, and how total and cohort-specific abundance relate to climate variables including those predicted to make the species vulnerable to climate change (i.e. temperatures exceeding preferred body temperature). We documented a decrease in lizard abundance over the last 40 years, and changes in the local climate. Population growth rate was related to the previous years' southern oscillation index; increasing following cooler-wetter, la niña years, decreasing following warmer-drier, el nino years. Within-year recruitment was negatively related to rainfall and minimum temperature. This study simultaneously identified climatic factors driving long-term population fluctuations and climate variables influencing short-term annual recruitment, both of which may be contributing to the population decline and influence the population's future persistence.

    Sweetening consists in removing gases, H{sub 2}S and CO{sub 2} and dehydration is for water. It is important to remove these contaminants, which is normally made through absorption: amines for H{sub 2}S and CO{sub 2}, and triethyleneglycol for water. For the study of these processes, the use of process commercial simulators is welcome. For the quality data acquisition many cares must be taken, such as, the good choice of the thermodynamic model and the suitable choice of the method for calculating of the equipment. In the amines process, where the absorption occurs with the chemical reaction in electrolyte environment, the model is fundamental. This work presents a methodology to analyze the different equilibrium models for sweetening and dehydration processes and selects the best one after the comparison with experimental data. It was introduced a new methodology for the efficiency calculation developed by Barros and Wolf, which is used for the simulation with phase equilibrium based method. The influence of the efficiency is more evident on the sweetening process than on the dehydration. Sensibility analyses were carried out in order to optimize the absorber and the regenerator, separately. With these optimized conditions, both processes were presented with recycle, focusing the reuse of the solvent. (author)

Utilizou-se a teoria de convergência-β condicional, adaptando o modelo de Barro e Sala-i-Martin, e incorporando a metodologia econométrica espacial. Não existe dependência espacial detectada pelo teste global mas o teste de dependência espacial local (LISA identificou um cluster de crescimento em uma região que é também pólo agropecuário do estado. Concluiu-se que há convergência-β condicional nos municípios mato-grossenses. Ainda, se constatou econometricamente que o setor agropecuário se mostra importante para o crescimento econômico dos municípios. No entanto, considera-se interessante aprofundar esses estudos, levando em consideração as características municipais e regionais, a fim de reduzir as suas desigualdades e obter um processo de crescimento econômico mais eficaz.

    The primary objective of this study is to quantify the net emissions of key greenhouse gases (GHG) - notably, CO{sub 2} and CH{sub 4} - from hydropower reservoirs in moist temperate areas within the U.S. The rationale for this objective is straightforward: if net emissions of GHG can be determined, it would be possible to directly compare hydropower to other power-producing methods on a carbon-emissions basis. Studies of GHG emissions from hydropower reservoirs elsewhere suggest that net emissions can be moderately high in tropical areas. In such areas, warm temperatures and relatively high supply rates of labile organic matter can encourage high rates of decomposition, which (depending upon local conditions) can result in elevated releases of CO{sub 2} and CH{sub 4}. CO{sub 2} and CH{sub 4} emissions also tend to be higher for younger reservoirs than for older reservoirs, because vegetation and labile soil organic matter that is inundated when a reservoir is created can continue to decompose for several years (Galy-Lacaux et al. 1997, Barros et al. 2011). Water bodies located in climatically cooler areas, such as in boreal forests, could be expected to have lower net emissions of CO{sub 2} and CH{sub 4} because their organic carbon supplies tend to be relatively recalcitrant to microbial action and because cooler water temperatures are less conducive to decomposition.

C.ABSTRACT: The A. presents what she believes to be a new form of Hispanic «Sigillata», from rhe Roman «Villa» of Torre de Palma (Alentejo, Portugal and kept in the Museu Nacional de Arqueologia e Etnologia of Lisbon. It is a plain one-handled jar, which main characteristic is a circus round the mouth, rather uncummon either on «Sigillata» or on wraph wear. On the basis of some formal similitudes with Hispanic Form 20, mouthes found on glass-ware from the I I century on, and of the quality of the slip, the A. suggests, as a mere hypothesis, a chronology not far from the I I century a.D.

    Full Text Available Este texto tiene por finalidad rescatar diversos aspectos y debates en torno a la relación entre populismo y democracia. En ese sentido, expondremos los principales rasgos de las teorizaciones de autores como Margaret Canovan, Benjamín Arditi y Sebastián Barros para repensar los lazos entre aquellos dos términos. En un esfuerzo por no tomar a populismo y democracia como polos antitéticos en las formaciones políticas comunitarias, nos interesa resaltar el modo en que la idea de sombra y la de espectro han tenido centralidad en las concepciones de nuestros autores. Junto a esta reflexión, pretendemos retomar diversos núcleos discursivos de la experiencia del primer peronismo en la Argentina de mediados del siglo XX para indagar los modos en que la lógica del populismo peronista resignificó la democracia colocándola como elemento central de la identidad que se decía encarnar. Así, creemos que puede resultar interesante pensar no solo al populismo como espectro de la democracia sino también a la democracia como espectro del populismo.

    Full Text Available “O cinema brasileiro se despiu cedo”. A frase de Eduardo Parga (2008, p. 90 sintetiza a relação de proximidade entre o cinema produzido no Brasil e as representações de conteúdos eróticos. Já em 1916, Lucíola, adaptação do romance de José de Alencar dirigida por Franco Magliani, exibia uma cena de nudez da atriz Aurora Fúlgida. Mais tarde, em 1951, Virgínia Lane dançaria seminua em Anjo do Lodo, de Luís de Barros. Mas foi em meados dos anos 60 que o país descobriu o forte apelo popular do erotismo cinematográfico. Na posição de voyeur, protegido pela sala escura, um público ávido por saciar sua pulsão escópica passou a consumir amplamente uma nova espécie de filmes, que acrescentavam às suas tramas um sabor picante ao lançar mão de doses leves de nudez, malícia e sensualidade para atualizar a tradição das comédias populares urbanas

    Full Text Available Knowledge of the soil water retention curve (SWRC is essential for understanding and modeling hydraulic processes in the soil. However, direct determination of the SWRC is time consuming and costly. In addition, it requires a large number of samples, due to the high spatial and temporal variability of soil hydraulic properties. An alternative is the use of models, called pedotransfer functions (PTFs, which estimate the SWRC from easy-to-measure properties. The aim of this paper was to test the accuracy of 16 point or parametric PTFs reported in the literature on different soils from the south and southeast of the State of Pará, Brazil. The PTFs tested were proposed by Pidgeon (1972, Lal (1979, Aina & Periaswamy (1985, Arruda et al. (1987, Dijkerman (1988, Vereecken et al. (1989, Batjes (1996, van den Berg et al. (1997, Tomasella et al. (2000, Hodnett & Tomasella (2002, Oliveira et al. (2002, and Barros (2010. We used a database that includes soil texture (sand, silt, and clay, bulk density, soil organic carbon, soil pH, cation exchange capacity, and the SWRC. Most of the PTFs tested did not show good performance in estimating the SWRC. The parametric PTFs, however, performed better than the point PTFs in assessing the SWRC in the tested region. Among the parametric PTFs, those proposed by Tomasella et al. (2000 achieved the best accuracy in estimating the empirical parameters of the van Genuchten (1980 model, especially when tested in the top soil layer.

  13. Mass determination of K2-19b and K2-19c from radial velocities and transit timing variations

    2017-03-01

    We present FIES@NOT and HARPS-N@TNG radial velocity follow-up observations of K2-19, a compact planetary system hosting three planets, of which the two larger ones, namely K2-19b and K2-19c, are close to the 3:2 mean motion resonance. The masses of these larger planets have previously been derived from transit timing only. An analysis considering only the radial velocity measurements is able to detect only K2-19b, the largest and more massive planet in the system, with a mass of 71.7 ± 6.3 M_{Jupiter}. We also used the TRADES code to simultaneously model both our RV measurements and the existing transit-timing measurements. We derived a mass of K2-19b of 59.5^{+7.2} _{-11.4} M_{Jupiter} and of K2-19c of 9.7 ^{+3.9} _{-2.0} M_{oplus}. A prior K2-19b mass estimated by Barros et al. (2015), based exclusively on transit timing measurements, is only consistent with our combined TTV and RV analysis, but not with our analysis based purely on RV measurements. K2-19b supports the suspicion that planet masses and densities involving TTV data are systematically lower than those based purely on RV measurements.

    Full Text Available The present text aims to retake several aspects and debates concerning the relation between populism and democracy. We will expound the main ideas by authors such as Margaret Canovan, Benjamín Arditi and Sebastián Barros in order to rethink the bonds between both terms. We will try not to take populism and democracy as antithetical poles in communitary political associations, since we are interested in pointing out how the ideas of shadow and specter have been crucial in the thought of these authors. Along with this reflection we seek to revisit several discursive keys of the experience of first Peronism in twentieth-century Argentina, just to investigate the ways in which the logic of Peronist populism rethought democracy and set it as a central element of the identity that it claimed to embody. Thus, we think that may be interesting not just to think populism as a specter of democracy but also to think democracy as a specter of populism.

    The impacts of climate change on forest community composition are still not well known. Although directional trends in climate change and community composition change were reported in recent years, further quantitative analyses are urgently needed. Previous studies focused on measuring population growth rates in a single time period, neglecting the development of the populations. Here we aimed to compose a method for calculating the community composition change, and to testify the impacts of climate change on community composition change within a relatively short period (several decades) based on long-term monitoring data from two plots-Dinghushan Biosphere Reserve, China (DBR) and Barro Colorado Island, Panama (BCI)-that are located in tropical and subtropical regions. We proposed a relatively more concise index, Slnλ, which refers to an overall population growth rate based on the dominant species in a community. The results indicated that the population growth rate of a majority of populations has decreased over the past few decades. This decrease was mainly caused by population development. The increasing temperature had a positive effect on population growth rates and community change rates. Our results promote understanding and explaining variations in population growth rates and community composition rates, and are helpful to predict population dynamics and population responses to climate change.

    Full Text Available Climate change threatens biodiversity worldwide, however predicting how particular species will respond is difficult because climate varies spatially, complex factors regulate population abundance, and species vary in their susceptibility to climate change. Studies need to incorporate these factors with long-term data in order to link climate change to population abundance. We used 40 years of lizard abundance data and local climate data from Barro Colorado Island to ask how climate, total lizard abundance and cohort-specific abundance have changed over time, and how total and cohort-specific abundance relate to climate variables including those predicted to make the species vulnerable to climate change (i.e. temperatures exceeding preferred body temperature. We documented a decrease in lizard abundance over the last 40 years, and changes in the local climate. Population growth rate was related to the previous years' southern oscillation index; increasing following cooler-wetter, la niña years, decreasing following warmer-drier, el nino years. Within-year recruitment was negatively related to rainfall and minimum temperature. This study simultaneously identified climatic factors driving long-term population fluctuations and climate variables influencing short-term annual recruitment, both of which may be contributing to the population decline and influence the population's future persistence.

    Alterations in sphingolipid metabolism, especially ceramide and sphingosine 1-phosphate, have been linked to colon cancer, suggesting that enzymes of sphingolipid metabolism may emerge as novel regulators and targets in colon cancer. Neutral ceramidase (nCDase), a key enzyme in sphingolipid metabolism that hydrolyzes ceramide into sphingosine, is highly expressed in the intestine; however, its role in colon cancer has not been defined. Here we show that molecular and pharmacological inhibition of nCDase in colon cancer cells increases ceramide, and this is accompanied by decreased cell survival and increased apoptosis and autophagy, with minimal effects on noncancerous cells. Inhibition of nCDase resulted in loss of β-catenin and inhibition of ERK, components of pathways relevant for colon cancer development. Furthermore, inhibition of nCDase in a xenograft model delayed tumor growth and increased ceramide while decreasing proliferation. It is noteworthy that mice lacking nCDase treated with azoxymethane were protected from tumor formation. Taken together, these studies show that nCDase is pivotal for regulating initiation and development of colon cancer, and these data suggest that this enzyme is a suitable and novel target for colon cancer therapy.—García-Barros, M., Coant, N., Kawamori, T., Wada, M., Snider, A.

    Full Text Available This study examines economic growth and population change with discrimination against women in the labor market within the analytical framework of Solow’s neoclassical growth model. The study models dynamic interactions between wealth accumulation, time distribution between work, children caring, and leisure, population change with endogenous birth and mortality rates with gender discrimination. The production technology and markets are built on Solow’s neoclassical growth model. The basic mechanisms for population changes in the Barro-Becker fertility choice model and the Haavelmo population model are integrated to model the population change. This study also takes account of discrimination against woman in the labor market. We synthesize these dynamic forces in a compact framework by applying Zhang’s utility function. The model properties are studied by simulation. We find equilibrium points and illustrate motion of the dynamic system. We also examine the effects of changes in the discrimination against woman, the propensity to save, woman’s propensity to pursue leisure activities, the propensity to have children, woman’s human capital and man’s emotional involvement in children caring.

    Full Text Available Morphometric measurements are important to evaluate the variability, determine the racial standard and the existence of sexual dimorphism in genetic group. With this objective, were measured 20 morphometric measurements and one measurements of weight for 338 animals of the genetic group of Sul-mato-grossenses naturalized sheep belonging to Manoel de Barros Foundation and breeding at Centro Tecnologico de Ovinos from Anhanguera-Uniderp University and Federal University of the Grande Dourados. The statistical analyses were realized through software SAS. The females and young males showed short variation for morphometric measured of head and limbs region. However, higher variation was observed in the morphometric measurements taken from torso region, indicate that this region could be inserted in breeding programs like a selection criterion. The Pearson correlation coefficients between the morphostructural characteristics of females and young males, appears to have certain harmony degree in the morphostructural model. The females are characterized by animals with relatively large head, torso with proportional features and good angulations. The gender did not influence characteristics of the head region and body weight in the young animals. However, the characteristics of other regions, such as thoracic perimeter and posterior width of rump measured in the head region, and the perimeter of carpal and metacarpal in the limbs were influenced by gender in young animals.

    Venezuelan table mountains (tepuis) host the largest arenite caves in the world. The most frequently used explanation of their origin so far was the "arenization" theory, involving dissolution of quartz cement around the sand grains and subsequent removing of the released grains by water. New research in the two largest arenite cave systems - Churi-Tepui System in Chimanta Massif and Ojos de Cristal System in Roraima Tepui showed that quartz dissolution plays only a minor role in their speleogenesis. Arenites forming the tepuis are not only quartzites but they display a wide range of lithification and breakdown, including also loose sands and sandstones. Speleogenetic processes are mostly concentrated on the beds of unlithified sands which escaped from diagenesis by being sealed by the surrounding perfectly lithified quartzites. Only the so-called "finger-flow" pillars testify to confined diagenetic fluids which flowed in narrow channels, leaving the surrounding arenite uncemented. Another factor which influenced the cave-forming processes by about 30% was lateritization. It affects beds formed of arkosic sandstones and greywackes which show strong dissolution of micas, feldspars and clay minerals, turning then to laterite ("Barro Rojo"). The main prerequisite to rank caves among karst phenomena is dissolution. As the dissolution of silicate minerals other than quartz appears to play not only a volumetrically important role but even a trigger role, these arenitic caves may be ranked as karst.

    The study of soil arthropods can provide valuable information how ecosystems respond to different management practices. The objective was to assess the total abundance, richness, and composition of epiedaphic arthropods in different agrosystems from southwestern Spain. Six sites with different agricultural uses were selected: olive grove, vineyards, olive grove with vineyards, wheat fields, fallows (150-300 m long), and abandoned vineyards. Crops were managed in extensive. Field margins were used as reference habitats. At the seven sites a total of 30 pitfall traps were arranged in a 10 × 3 grid. Traps were arranged to short (SD, 1 m), medium (MD, 6 m) and large (LD, 11 m) distance to the field margins in the middle of selected plots. Pitfall traps captured a total of 11,992 edaphic arthropods belonging to 11 different taxa. Soil fauna was numerically dominated by Formicidae (26.60%), Coleoptera (19.77%), and Aranae (16.76%). The higher number of soil arthropods were captured in the field margins followed by the abandoned vineyard. Significant differences were found between sites for total abundance, and zones. However, no significant differences for total abundance were found between months (April-July). Richness and diversity was highest in field margins and abandoned vineyards. Significant differences were found for these variables between sites. Our results suggest that agricultural intensification affects soil arthropods in Tierra de Barros area, a taxonomic group with an important role in the functioning of agricultural ecosystems.

    The history of insecticide resistance in the horn fly, Haematobia irritans, and the relationship between the characteristics of horn fly biology and insecticide use on resistance development is discussed. Colonies of susceptible horn flies were selected for resistance with six insecticide treatment regimens: continuous single use of permethrin, diazinon and ivermectin: permethrin-diazinon (1:2) mixture; and permethrin-diazinon and permethrin-ivermectin rotation (4-month cycle). Under laboratory conditions, resistance developed during generations 21, 31 and 30 to permethrin, diazinon and ivermectin, respectively. The magnitude of resistance ranged from horn-fly season resulted in product failure within 3-4 years for pyrethroids and organophosphates, respectively. In laboratory studies, use of alternating insecticides or a mixture of insecticides delayed the onset of resistance for up to 12 generations and reduced the magnitude of pyrethroid resistance. In field studies, yearly alternated use of pyrethroids and organophosphates did not slow or reverse pyrethroid resistance (Barros et al., unpublished data), while a 2-year alternated use with organophosphates resulted in partial reversion of pyrethroid resistance. When pyrethroid and organophosphate ear tags were used in a mosaic strategy at two different locations, efficacy of products did not change during a 3-year period.

    To determine the prevalence, treatment and control of diabetes mellitus (DM) and impaired fasting glucose (IFG) as well as associated factors in the adult population of four cities of the Southern Cone of Latin America (SCLA). This is a cross-sectional population-based study that included 7407 adults between 35 and 74 years old in four cities of the SCLA: Temuco (Chile), Marcos Paz and Bariloche (Argentina), and Pando-Barros Blancos (Uruguay). DM was defined as fasting plasma glucose ≥126 mg/dL or self-reported history of diabetes. Awareness, treatment, and control of DM were defined as subjects self-reporting a DM previous diagnosis, the use of a prescription medication or nonpharmacological intervention for DM, and fasting plasma glucose diabetes, 20% were newly diagnosed at the time of the study. Overall, 79.8% of patients with diabetes were aware of their condition. The treatment and control rate were 58.8% and 46.2%, respectively. Older age, family history of diabetes, lower educational attainment, overweight, obesity, central obesity, low physical activity, hypertension, hypercholesterolemia and hypertriglyceridemia were all significantly associated with an increased risk of diabetes. The prevalence of DM and IFG in the adult population of the SCLA is high and varies among cities. These conditions represent a public health challenge since the rates of awareness, treatment, and control are still low.

    Full Text Available Dioecious tropical tree species often have small flowers and fleshy fruits indicative of small-insect pollination and vertebrate seed dispersal. We hypothesize that seed mediated gene flow should be exceed pollen-mediated gene flow in such species, leading to weak patterns of fine scale spatial genetic structure (SGS. In the present study, we characterize novel microsatellite DNA markers and test for SGS in sapling (N=100 and adult trees (N=99 of the dioecious canopy tree Pouteria reticulata (Sapotaceae in a 50 ha forest dynamics plot on Barro Colorado Island (BCI, Panama. The five genetic markers contained between five and 15 alleles per locus, totaling 51 alleles in the sample population. Significant SGS at local spatial scales (<100m was detected in the sapling (dbh≈1cm and adult (dbh≥20cm size classes, but was stronger in the former (sapling Sp=0.010±0.004, adult Sp=0.006±0.002, suggesting demographic thinning. The degree of SGS was lower than the value expected for non-vertebrate dispersed tropical trees (Sp=0.029, but similar to the average value for vertebrate dispersed tropical trees (Sp=0.009 affirming the dispersal potential of vertebrate dispersed tropical trees in faunally intact forests.

  8. Changes in abundance of birds in a Neotropical forest fragment over 25 years: a review

    Robinson, W. D.

    2001-01-01

    Full Text Available Few data are available to evaluate the long term effects of habitat isolation on species richness or abundances in the tropics. Barro Colorado Island (BCI, Panama, has been studied for more than 80 years since its isolation from surrounding lowland forest when the Panama Canal was constructed. Thirty-five percent of the originally present 200 resident species have disappeared. Although the loss of species is well-studied, changes in abundance that might help predict future losses have not been evaluated. One study in 1970 and the present study conducted 25 years later estimated abundances of most bird species on BCI. Comparisons indicate at least 37 species have declined by at least 50%. Twenty-six species of edge habitats are expected to decline as forest maturation proceeds, yet 11 forest species that are now rare may be lost soon. All 26 species that were present in 1970 but not detected in the mid-1990s were rare in 1970. Thus, rarity appears to be a good predictor of extinction risk in this tropical habitat fragment.

    Full Text Available Ethnopedological studies have mainly focused on agricultural land uses and associated practices. Nevertheless, peasant and indigenous populations use soil and land resources for a number of additional purposes, including pottery. In the present study, we describe and analyze folk knowledge related to the use of soils in non-industrial pottery making by peasant potters, in the municipality of Altinho, Pernambuco State, semiarid region at Brazil. Ethnoscientific techniques were used to record local knowledge, with an emphasis on describing the soil materials recognized by the potters, the properties they used to identify those soil materials, and the criteria employed by them to differentiate and relate such materials. The potters recognized three categories of soil materials: “terra” (earth, “barro” (clay and, “piçarro” (soft rock. The multi-layered arrangement of these materials within the soil profiles was similar to the arrangement of the soil horizon described by formal pedologists. “Barro vermelho” (red clay was considered by potters as the principal ceramic resource. The potters followed morphological and utilitarian criteria in distinguishing the different soil materials. Soils from all of these sites were sodium-affected Alfisols and correspond to Typic Albaqualf and Typic Natraqualf in the Soil Taxonomy (Soil Survey Staff, 2010.

    Paul Celan’s poem Escape from death presents situations lived by himself in a Nazi concentration camp, which inserts the poem in the context of the literature of testimony; it is a poem fulfilled with high amount of drama, in which content and structure combine to offer a dense reading, loaded with meaning. One can see, in the poem, that silence dominates the scenery, expressing, through the many gaps left by a fragmentary language, what is difficult for the poet to express, the feelings which are impossible to talk about, what leads the reader to an astonishing feeling, making contact with the meaning only through stages and amid the gaps. This article approaches the poem starting from concepts related to Literature of testimony and the impossibility of representing the real (Roland Barthes; in what concern the formal aspects, beside the Bakhtin’s ideas about polyphony, and Barros and Fiorin’s studies about dialogism, polyphony and interdiscursivity; furthermore, starting from the musical concept of escape, as suggested by the title of the poem and highlighted in the text, we discuss figurative language – metaphor and metonymy, irony and ellipses, as the author's strategies to face the hesitation between trauma and representation so one have a silence poetic, in which the ellipses and metaphors play an essential role.

    Predation is an important selective pressure in natural ecosystems. Among non-human primates, relatively little is known about how predators hunt primate prey and how primates acquire adaptive responses to counteract predation. In this study we took advantage of the recent reintroduction of radio-tagged harpy eagles (Harpia harpyja) to Barro Colorado Island (BCI), Panama to explore how mantled howler monkeys (Alouatta palliata), one of their primary prey, acquire anti-predator defences. Based on the observation that harpies follow their prey prior to attack, and often call during this pursuit period, we broadcast harpy eagle calls to howlers on BCI as well as to a nearby control population with no harpy predation. Although harpies have been extinct from this area for 50-100 years, results indicate that BCI howlers rapidly acquired an adaptive anti-predator response to harpy calls, while showing no response to other avian vocalizations; howlers maintained this response several months after the removal of the eagles. These results not only show that non-human primates can rapidly acquire an alarm response to a newly introduced predator, but that they can detect and identify predators on the basis of acoustic cues alone. These findings have significant implications both for the role of learning mechanisms in the evolution of prey defence and for conservation strategies, suggesting that the use of 'probing' approaches, such as auditory playbacks, may highly enhance an a priori assessment of the impact of species reintroduction.

Classification of AIHA is based on the optimal auto-RBC antibody reactivity temperatures and includes warm, cold-reactive, mixed AIHA, and drug-induced AIHA subtypes. AIHA is a rare disease, and recommendations for transfusion are based mainly on results from retrospective data and relatively small cohort studies, including heterogeneous patient samples or single case reports. In this article, we will review the challenges and solutions to safely transfuse AIHA patients. We will reflect on the indication for transfusion in AIHA and the difficulty in the accomplishment of immunohematological procedures for the selection of the safest and most compatible RBC units.

    Full Text Available Gabriela Mistral and Pedro Aguirre Cerda made acquaintance of themselves in 1916. Since then, they maintained correspondence until 1941. The paper is based on a set of twenty-seven letters written by Gabriela Mistral to Pedro Aguirre Cerda from different places of the world, published in Mapocho journal in 1977. It also includes the Epistolario de Gabriela Mistral issued in the Epistolario de Pedro Aguirre Cerda (1938-1941 published by the Centro de Estudios Barros Arana. Finally, it incorporates a letter by Juana Aguirre de Aguirre to Mistral, dated in 1942. This is completed by different references that both of them made in their letters to other people. The paper reviews four aspects of the relation between Gabriela Mistral and Pedro Aguirre Cerda. The first topic is in regard to the poetess daily life aspects. A second question its related with Gabriela Mistral’s professional matters, specially the ones connected with her labor as an educator, as an international government employee and as a publicist of our country in other places of the world. The third issue is related to the poetess’s opinions concerning issues about Chilean politics. Finally, the fourth topic is in relation with subjects concerning Mistral’s private life and personal opinions.

    Full Text Available Throughout his works, Bartolomé Jiménez Patón mentions Portugal and some of its writers on a number of occasions. In the books that have been recovered of his Comentarios de erudición (1621, he cites authors such as Fernando López de Castañeda or Joao de Barros, who are associated with the popular vogue of the period for portentous works, of which the Spanish Humanist was so fond of. A large number of his commentaries concerning Portugal center on justifying dynastic unity, based on his interpretation of the history of Gregorio López Madera, who he admired so much, which has as its background the image of Hispania. To a certain extent, the new government of Olivares would try to carry out this policy. Of no less interest is his description of the city of Lisbon in which he presents the idea of ‘exemplariness’, a notion he has in common with other descriptions by Mateo Alemán, Cervantes or Tirso, although in Patón’s, such exemplariness appears in contrast with the picturesque depiction of the rogues of the Rua Nova.

    Species identification and characterization in tropical environments is an emerging field in tropical remote sensing. Significant efforts are currently aimed at the detection of tree species, of levels of forest successional stages, and the extent of liana occurrence at the top of canopies. In this paper we describe our use of high resolution imagery from the Quickbird Satellite to estimate the flowering population of Tabebuia guayacan trees at Barro Colorado Island (BCI), in Panama. The imagery was acquired on 29 April 2002 and 21 March 2004. Spectral Angle Mapping via a One-Class Support Vector machine was used to detect the presence of 422 and 557 flowering tress in the April 2002 and March 2004 imagery. Of these, 273 flowering trees are common to both dates. This study presents a new perspective on the effectiveness of high resolution remote sensing for monitoring a phenological response and its use as a tool for potential conservation and management of natural resources in tropical environments.

He called this new field C­ programming, standing for composite concave programming. In his seminal book on dynamic programming (Ref. [104]), Sniedovich shows how the study of such com­ positions can help tackling non-separable dynamic programs that otherwise would defeat solution. Barros and Frenk (Ref.

More recently, this algorithm has been used by Carrizosa and Plastria to solve a global optimization problem in facility location (Ref. [16]). The distinction between global optimization problems (Ref. [54]) and generalized convex problems can sometimes be hard to establish. That is exactly the reason ...

  1. Non-selective cation channels and oxidative stress- induced cell swelling

    2002-01-01

    Full Text Available Necrosis is considered as a non-specific form of cell death that induces tissue inflammation and is preceded by cell swelling. This increase in cell volume has been ascribed mainly to defective outward pumping of Na+ caused by metabolic depletion and/or to increased Na+ influx via membrane transporters. A specific mechanism of swelling and necrosis driven by the influx of Na+ through nonselective cation channels has been recently proposed (Barros et al., 2001a. We have characterized further the properties of the nonselective cation channel (NSCC in HTC cells. The NSCC shows a conductance of ~18 pS, is equally permeable to Na+ and K+, impermeant to Ca2+, requires high intracellular Ca2+ as well as low intracellular ATP for activation and is inhibited by flufenamic acid. Hydrogen peroxide induced a significant increase in cell volume that was dependent on external Na+. We propose that the NSCC, which is ubiquitous though largely inactive in healthy cells, becomes activated under severe oxidative stress. The ensuing Na+ influx initiates via positive feedback a series of metabolic and electrolytic disturbances, resulting in cell death by necrosis

    Alterations in sphingolipid metabolism, especially ceramide and sphingosine 1-phosphate, have been linked to colon cancer, suggesting that enzymes of sphingolipid metabolism may emerge as novel regulators and targets in colon cancer. Neutral ceramidase (nCDase), a key enzyme in sphingolipid metabolism that hydrolyzes ceramide into sphingosine, is highly expressed in the intestine; however, its role in colon cancer has not been defined. Here we show that molecular and pharmacological inhibition of nCDase in colon cancer cells increases ceramide, and this is accompanied by decreased cell survival and increased apoptosis and autophagy, with minimal effects on noncancerous cells. Inhibition of nCDase resulted in loss of β-catenin and inhibition of ERK, components of pathways relevant for colon cancer development. Furthermore, inhibition of nCDase in a xenograft model delayed tumor growth and increased ceramide while decreasing proliferation. It is noteworthy that mice lacking nCDase treated with azoxymethane were protected from tumor formation. Taken together, these studies show that nCDase is pivotal for regulating initiation and development of colon cancer, and these data suggest that this enzyme is a suitable and novel target for colon cancer therapy.-García-Barros, M., Coant, N., Kawamori, T., Wada, M., Snider, A.

    Assessing the relative importance of different processes that determine the spatial distribution of species and the dynamics in highly diverse plant communities remains a challenging question in ecology. Previous modelling approaches often focused on single aggregated forest diversity patterns that convey limited information on the underlying dynamic processes. Here, we use recent advances in inference for stochastic simulation models to evaluate the ability of a spatially explicit and spatially continuous neutral model to quantitatively predict six spatial and non-spatial patterns observed at the 50 ha tropical forest plot on Barro Colorado Island, Panama. The patterns capture different aspects of forest dynamics and biodiversity structure, such as annual mortality rate, species richness, species abundance distribution, beta-diversity and the species-area relationship (SAR). The model correctly predicted each pattern independently and up to five patterns simultaneously. However, the model was unable to match the SAR and beta-diversity simultaneously. Our study moves previous theory towards a dynamic spatial theory of biodiversity and demonstrates the value of spatial data to identify ecological processes. This opens up new avenues to evaluate the consequences of additional process for community assembly and dynamics.

    Solid polymer electrolytes (SPEs) synthesized by the sol-gel process and designated as di-ureasils have been prepared through the incorporation of lithium perchlorate, LiClO 4 , into the d-U(2000) organic-inorganic hybrid network. Electrolytes with lithium salt compositions of n (where n indicates the number of oxyethylene units per Li + ion) between ∞ and 0.5 were characterized by conductivity measurements, cyclic voltammetry at a gold microelectrode, thermal analysis and Fourier transform Raman (FT-Raman) spectroscopy. The conductivity results obtained suggest that this system offers a quite significant improvement over previously characterized analogues doped with lithium triflate [S.C.

'Free' perchlorate ions, detected in all the samples examined, are identified as the main charge carriers in the sample that yields the highest room temperature conductivity (n = 20).

    Gammaherpesviruses (GHVs) have been identified in many species and are often associated with disease. Recently, we characterized three novel felid GHVs in domestic cats (Felis catus), bobcats (Lynx rufus), and pumas (Puma concolor). We investigated whether free-ranging ocelots (Leopardus pardalis) and bobcats are infected with additional GHVs. We screened DNA samples from ocelots on Barro Colorado Island, Panama, and bobcats in western Colorado, US, by using a degenerate nested PCR that targets the GHV glycoprotein B gene. We identified a novel GHV glycoprotein B sequence in two ocelots and a second novel sequence in a bobcat, which is distinct from the previously characterized bobcat GHV (Lynx rufus GHV 1). Utilizing additional degenerate and virus-specific PCRs, we extended these sequences to include 3.4 kilobases of the GHV glycoprotein B and DNA polymerase genes. These sequences identify the first GHV detected in ocelots and the second GHV in bobcats. These viruses were provisionally named L. pardalis GHV 1 and Lynx rufus GHV 2, respectively. The viruses are most closely related to recently identified GHVs of the Percavirus genus found in domestic cats (F. catus GHV 1) and bobcats (L. rufus GHV 1), suggesting that a cluster of felid GHVs exists within the Percavirus genus.

    Full Text Available Quality of public finances belongs to a key policy challenge as its improvement should lead to a long-term economic growth. The aim of the paper is to investigate if the key channels and tools used by the public finance (structure of revenue system, size of the government and composition of expenditure, level and sustainability of fiscal position affect economic growth in the Czech Republic in the period 1995-2013. The empirical model is based on the methodology of Barro and Sala-i-Martin (2003 and the model of Mankiw et al. (1992 which is adapted to the framework of this study. The results of dynamic regressions suggest that economic growth is affected by public finance variables only partly and traditional sources of economic growth (human capital or openness play bigger role. Provided evidence shows that total tax burden as well as the structure of revenue system (especially implicit tax rates on labour and consumption should be primarily used as tools for maintain macroeconomic objectives. On the contrary, changes in size and composition of expenditure, balance and debt report not statistically significant impact.

    Seed dispersal is a critical but poorly understood life-history stage of plants. Here we use a genetic approach to describe seed dispersal patterns accurately in a natural population of the Neotropical tree species Jacaranda copaia (Bignoniaceae). We used microsatellite genotypes from maternally derived tissue on the diaspore to identify which individual of all possible adult trees in the population was the true source of a given seed collected after it dispersed. Wind-dispersed seeds were captured in two different years in a large array of seed traps in an 84-ha mapped area of tropical forest on Barro Colorado Island, Panama. We were particularly interested in the proportion of seeds that traveled long distances and whether there was evidence for direct dispersal into gaps, which are required for successful recruitment of this pioneer tree species. Maximum likelihood procedures were used to fit single- and multiple-component dispersal kernels to the distance data. Mixture models, with separate distributions near and far, best fit the observed dispersal distances, albeit with considerable uncertainty in the tail. We discuss the results in light of different mechanisms responsible for separate distributions near the adult source and in the tail of the curve.

    Angiosperms (flowering plants) are strikingly diverse. This is clearly expressed in the morphology of their pollen grains, which are characterized by enormous variety in their shape and patterning. In this paper, I approach angiosperm pollen morphology from the perspective of enumerative combinatorics. This involves generating angiosperm pollen morphotypes by algorithmically combining character states and enumerating the results of these combinations. I use this approach to generate 3 643 200 pollen morphotypes, which I visualize using a parallel-coordinates plot. This represents a raw morphospace. To compare real-world and theoretical morphologies, I map the pollen of 1008 species of Neotropical angiosperms growing on Barro Colorado Island (BCI), Panama, onto this raw morphospace. This highlights that, in addition to their well-documented taxonomic diversity, Neotropical rainforests also represent an enormous reservoir of morphological diversity. Angiosperm pollen morphospace at BCI has been filled mostly by pollen morphotypes that are unique to single plant species. Repetition of pollen morphotypes among higher taxa at BCI reflects both constraint and convergence. This combinatorial approach to morphology addresses the complexity that results from large numbers of discrete character combinations and could be employed in any situation where organismal form can be captured by discrete morphological characters. © 2016 The Author(s).

  17. New documents for the biography of Miguel de Cervantes Saavedra, a royal commissar of supplies in the former Kingdoms of Jaen and Seville (1592-1593

    Full Text Available The recent finding of new testimonies on Miguel de Cervantes life, preserved in several Sevillian archives, has helped to clarify his presence in Seville and other places of this region exercising as Royal Commissioner of Supplies in spring of 1593. These testimonies clarify a dark period in his biography, and increase our knowledge of his activities in Porcuna (Jaén as Royal Commissar of Supplies in January 1592. The new documentation offers information about an unknown commission entrusted on February 21 1593 to Cervantes by Cristobal de Barros, the general supplier of the Carrera de las Indias’ fleet. These papers also provide the name of a Sevillian woman, Magdalena Enriquez, a merchant who manufacture “biscochos” for the Navy, who legally was authorized by Cervantes to collect the salary owed for his services in that institution. It is remarkable the narrow relation of friendship between Cervantes and this woman, and also with Tomas Gutiérrez. In sum, this article provides fourteen new Cervantian documents that I meet and transcribe for Anales Cervantinos. Six of these documents were already edited between 2014 and 2015, and the other eight are published for the first time. With this documentary contribution new research routes are open to penetrate into the enigmatic life of the author of Don Quixote.

  20. Plant Species Richness is Associated with Canopy Height and Topography in a Neotropical Forest

    Full Text Available Most plant species are non-randomly distributed across environmental gradients in light, water, and nutrients. In tropical forests, these gradients result from biophysical processes related to the structure of the canopy and terrain, but how does species richness in tropical forests vary over such gradients, and can remote sensing capture this variation? Using airborne lidar, we tested the extent to which variation in tree species richness is statistically explained by lidar-measured structural variation in canopy height and terrain in the extensively studied, stem-mapped 50-ha plot on Barro Colorado Island (BCI, Panama. We detected differences in species richness associated with variation in canopy height and topography across spatial scales ranging from 0.01-ha to 1.0-ha. However, species richness was most strongly associated with structural variation at the 1.0-ha scale. We developed a predictive generalized least squares model of species richness at the 1.0-ha scale (R2 = 0.479, RMSE = 8.3 species using the mean and standard deviation of canopy height, mean elevation, and terrain curvature. The model demonstrates that lidar-derived measures of forest and terrain structure can capture a significant fraction of observed variation in tree species richness in tropical forests on local-scales.

    Full Text Available The aim of this research is to build and analyze a parallel corpus in the field of remote sensing in order to identify, according to its frequency, specialized collocations in English and then search for their equivalents in Portuguese. The research is based on the interdisciplinary approach of Corpus-Based Translation Studies (BAKER, 1995; CAMARGO, 2007, Corpus Linguistics (BERBER SARDINHA, 2004; TOGNINI-BONELLI, 2001, Phraseology (ORENHA-OTTAIANO, 2009; PAVEL, 1993, and some principles of Terminology (BARROS, 2004. For manipulating the corpora, the program WordSmith Tools (SCOTT, 2012 version 6.0 is used. To support this study, two comparable corpora in English and Portuguese were also built from articles published in both national and international journals in remote sensing. The results show that the collocations in Portuguese seem to be still in the process of conventionalization, as the translators made use of greater variation in their translational options, which can be a way to make the text clearer for the reader.

    introducción en las fábricas de grandes cantidades de agua. Los tapiales de la torre de Cisneros son, composicional y texturalmente, muy similares entre sí, lo que indica que, a pesar de sus grandes dimensiones, se cuidó la homogeneidad de los materiales. Estos tapiales guardan una notable similitud con los de la iglesia de Villada. La materia prima original es barro con algunos aditivos (escombro, cenizas, huesos, etc. y algunos restos de cal empleada como estabilizante. Aunque la proporción de arcilla es muy elevada no se han detectado arcillas hinchables, de lo que se deduce que una vez construido el tapial no se habrían producido importantes cambios de volumen por variaciones de humedad de las fábricas. Las características del adobe de la torre de Boada son lógicamente diferentes de las de los tapiales estando constituido por un barro menos arenoso, más arcilloso, con una elevada proporción de paja que no tienen los tapiales y sin adiciones de ladrillos, huesos, etc.

    The Lagoa Real Uranium Province (PULR) is located in the center-south of the Bahia State, in the central part of Sao Francisco Craton and consists of an association of Paleoproterozoic meta-granites, alkali-gneiss, albitites, meta-leucodiorite and charnockites. This work has as objective the studies of the magmatic association, trying to understand its petrological and evolutionary meaning. For this purpose, representative bodies were sampled in order to develop unpublished studies of litogeochemistry, isotopes, geochronology and mineral chemistry. These analyzes were performed in: different preserved granitoid facies (Lagoa do Barro, Sao Timoteo, Juazeirinho and late pegmatitic phases), the meta-leucodiorites and charnockite. The data obtained using several modern methodologies, such as geochronology and mineral chemistry by LA-ICP-MS, provided results that allowed the characterization of two magmatic lithologies not described in the literature (Juazeirinho granite e late pegmatitic phases), and also a lithology preliminarily described (Lagoa do Barro granite). Moreover, these data contributed to elucidate the origin and meaning of the leucodiorite and charnoquito varieties, and made it possible to verify new compositional and mineral chemistry tendencies of Sao Timoteo granite. The data presented show that the studied granites were affected by albititization events (tardi or post-magmatic), which have different micro-chemical characteristics from the processes of albite formation related to the non-mineralized albitites bodies. Three albititization events were identified: a) An event that affected the granites characterized by the formation of albite with Rb and U, (b) Another event related to fluids associated with late pegmatitic bodies that formed albite with high levels of U, Rb and Ba, and partially affected the granites of the next pegmatoids portions; and (c) a final albititization event that caused the formation of the albite gneiss bodies, with albite

    Full Text Available The geographic distributions of the butterflies endemic to the Western Palaearctic are used to classify operative area units based on an index of association, and on parsimony analyses, and these results are compared. It is shown that the PAE-PCE method proposed by García-Barros et al. (2002 does not warrant detection of all subsets of area units characterised by endemic elements with identic distributions. However, satisfactory results can be achieved if Wager parsimony is subtituted by a method of cladogram construction that proscibes homoplasy, such as compatibility. When used as a classification procedure, the results of parsimony analysis can be broadly consistent with those derived from other procedures of hyerarchical classification. A distinction should be made between two different usages of parsimony, both of which represent ‘static’ (sensu Rosen, 1988 interpretations of area cladograms: PAE in a strict sense, aimed at detecting putative areas of endemicity. These are potentially overlapping entities, and hence the method may imply potentially multiple solutions. And, cladistic procedures applied as an agglomerative method (ideally with a single, most parsimonious solution. As far as the butterfly faunas are concered, the highest concentration of endemisms occur across the western circum-mediterranean mountain chains, and in the largest Mediterranean islands. The Iberian Peninsula is featured not just by a high concentration of endemic butterflies, but also by the coexistence of several distinc areas of endemism. Broad patterns derived from the endemic fauna fit well to those based on the whole butterfly fauna.

This study was performed to describe and analyze chemical, physical and morphological characteristics of sodium-affected Alfisols employed in traditional pottery; and to compare, through statistical analysis, pedogenetical horizons and soil layers, as recognized in soil profiles by professional researchers and potter-farmers, respectively. Fieldwork was performed in Chã da Pia, a rural village in the municipality of Areia, in the Agreste region of the State of Paraíba, Northeast Brazil. Ethnoscientific techniques were used to describe and analyze soil knowledge of potter-farmers who played the role of informants. A comparison of soil categories recognized by farmers and researchers was performed through discriminant-canonical analysis. Soils from which local people obtain a material named "barro de loiça" (pottery clay were classified as Typic Natraqualf and Vertic Albaqualf, according to Soil Taxonomy. Potter-farmers were able to identify differences between the tillable topsoil and underlying layers from which they extract ceramic clay. Some soil layers, recognized by potter-farmers, were similar to pedogenetic horizons of the same soils, recognized by researchers, in terms of physical, chemical and morphological characteristics. Discriminant-canonical analysis was a useful tool to articulate and compare information related to soil knowledge held by distinct social groups.As decisões e ações de uso e manejo adotadas pelas populações rurais são, em grande parte, baseadas no conhecimento pedológico local.

De esta colección, hemos seleccionado aquellas piezas de mayor interés, como son los ídolos, y los hemos dividido por tipos. En ellos se encuentra un variado muestrario: betilos, placas, falanges decoradas, planos-oculados, antropomorfos, bicónicos (tolvas, los llamados alcachofas o pinas, figuras zoomorfas y otras de difícil encuadre tipológico. Los más importantes son los ídolos con tema oculado y los antropomorfos. Los primeros se caracterizan por su forma rectangular o trapezoidal y sección plana. En el anverso, ojos circulares, cejas pobladas y tatuaje facial. En el reverso, líneas en zig-zag. Es un tipo abundante y, por el momento, su aparición se limita a la cuenca media del Guadiana. Los antropomorfos están fabricados de mármol, los primeros en la península realizados con este material. Los encontramos masculinos y femeninos. Presentan los mismos elementos que los óculados, lo cual, les hace diferentes de los cicládidos. Su número también es abundante en comparación con las piezas aparecidas hasta ahora en nuestra península. En conjunto, el yacimiento se relaciona más con materiales portugueses pero con unas características propias. Corresponde al Calcolítico tardío y su estudio sería muy interesante para conocer este momento en la cuenca del Guadiana.ABSTRACT: In the settlement of «La Pijotilla», located between Solana de los Barros and Talavera la Real, it has been collected, on the surface, a fair number of archeological materials by the Dominguez's family.

O objetivo deste estudo foi avaliar os resultados da indução de parto em casos de óbito fetal intra-útero com idade gestacional a partir de 20 semanas. Foi um estudo clínico descritivo realizado no Hospital Maternidade Leonor Mendes de Barros, em São Paulo. Foram analisadas 122 gestantes com esse diagnóstico quanto às características sociodemográficas, causas de óbito fetal, antecedentes obstétricos e características do parto (forma de indução, via de parto, complicações. Os procedimentos estatísticos utilizados foram cálculo da média e desvio-padrão e chi². As principais causas identificadas de morte fetal foram hipertensão arterial e infecções. A droga mais utilizada para a indução do parto foi o misoprostol (37,7%, seguido da ocitocina (19,7%. Em 27% dos casos o trabalho de parto iniciou espontaneamente. O tempo médio de indução foi de 3 horas. A maior parte teve parto vaginal e em 9,1% a cesárea foi realizada. Concluiu-se que a indução de parto de feto morto é segura e eficaz, independentemente do método utilizado. O misoprostol, utilizado por via vaginal, é especialmente útil nos casos de colo desfavorável, por seu efeito modificador sobre ele.Although 80 to 90% of all dead fetuses may be spontaneously eliminated after two to three weeks from death, labor induction has been the mostly used management.

    Predicting solutes displacement in ecosystems is a complex task because of heterogeneity of hydrogeological properties and limited financial resources for characterization. As a consequence, solute transport model predictions are subject to uncertainty and probabilistic methods are invoked. Despite the significant theoretical advances in subsurface hydrology, there is a compelling need to transfer those specialized know-hows into an easy-to-use practical tool. The deterministic approach is able to capture some features of the transport behavior but its adoption in practical applications (e.g. remediation strategies or health risk assessment) is often inadequate because of its inability to accurately model the phenomena triggered by the spatial heterogeneity. The rigorous evaluation of the local contaminant concentration in natural aquifers requires an accurate estimate of the domain properties and huge computational times; those aspects limit the adoption of fully 3D numerical models. In this presentation, we illustrate a physically-based methodology to analytically estimate of the statistics of the solute concentration in natural aquifers and the related health risk. Our methodology aims to provide a simple tool for a quick assessment of the contamination level in aquifers, as function of a few relevant, physically based parameters such as the log conductivity variance, the mean flow velocity, the Péclet number. Solutions of the 3D analytical model adopt the results of previous works: transport model is based on the solutions proposed by Zarlenga and Fiori (2013, 2014) where semi-analytical relations for the statics of local contaminant concentration are carry out through a Lagrangian first-order model. As suggested in de Barros and Fiori (2014), the Beta distribution is assumed for the concentration cumulative density function (CDF). We illustrate the use of the closed-form equations for the probability of local contaminant concentration and health risk in a

  19. Growth strategies of tropical tree species: disentangling light and size effects.

    Directory of Open Access Journals (Sweden)

    Nadja Rüger

    Full Text Available An understanding of the drivers of tree growth at the species level is required to predict likely changes of carbon stocks and biodiversity when environmental conditions change. Especially in species-rich tropical forests, it is largely unknown how species differ in their response of growth to resource availability and individual size. We use a hierarchical bayesian approach to quantify the impact of light availability and tree diameter on growth of 274 woody species in a 50-ha long-term forest census plot in Barro Colorado Island, Panama. Light reaching each individual tree was estimated from yearly vertical censuses of canopy density. The hierarchical bayesian approach allowed accounting for different sources of error, such as negative growth observations, and including rare species correctly weighted by their abundance. All species grew faster at higher light. Exponents of a power function relating growth to light were mostly between 0 and 1. This indicates that nearly all species exhibit a decelerating increase of growth with light. In contrast, estimated growth rates at standardized conditions (5 cm dbh, 5% light varied over a 9-fold range and reflect strong growth-strategy differentiation between the species. As a consequence, growth rankings of the species at low (2% and high light (20% were highly correlated. Rare species tended to grow faster and showed a greater sensitivity to light than abundant species. Overall, tree size was less important for growth than light and about half the species were predicted to grow faster in diameter when bigger or smaller, respectively. Together light availability and tree diameter only explained on average 12% of the variation in growth rates. Thus, other factors such as soil characteristics, herbivory, or pathogens may contribute considerably to shaping tree growth in the tropics.

    In April 2009, the Intergovernmental Panel on Climate Change (IPCC) decided to prepare a new special report with involvement of the UN International Strategy for Disaster Reduction (ISDR) on the topic "Managing the Risks of Extreme Events and Disasters to Advance Climate Change Adaptation" (SREX, http://ipcc-wg2.gov/SREX/). This special report reviews the scientific literature on past and projected changes in weather and climate extremes, and the relevance of such changes to disaster risk reduction and climate change adaptation. The SREX Summary for Policymakers was approved at an IPCC Plenary session on November 14-18, 2011, and the full report is planned for release in February 2012. This presentation will provide an overview on the structure and contents of the SREX, focusing on Chapter 3: "Changes in climate extremes and their impacts on the natural physical environment" [1]. It will in particular present the main findings of the chapter, including differences between the SREX's conclusions and those of the IPCC Fourth Assessment of 2007, and the implications of this new assessment for disaster risk reduction. Finally, aspects relevant to impacts on the biogeochemical cycles will also be addressed. [1] Seneviratne, S.I., N. Nicholls, D. Easterling, C.M. Goodess, S. Kanae, J. Kossin, Y. Luo, J. Marengo, K.

  1. The impact of lianas on the carbon cycle of tropical forests: a modeling study using the Ecosystem Demography model

    Lianas are an important component of tropical forests, constituting up to 40% of the woody stems and about 35% of the woody species. Tropical forests have been experiencing large-scale structural changes, including an increase in liana abundance and biomass. This may eventually reduce the projected carbon sink of tropical forests. Despite their crucial role no single terrestrial ecosystem model has included lianas so far. Here, we present the very first implementation of lianas in the Ecosystem Demography model (ED2). ED2 is able to represent the competition for water and light between different vegetation types at the regional level. Our new implementation of ED2 is hence suitable to address important questions such as the impact of lianas on the tropical forest carbon balance. We validated the model against forest inventory and eddy covariance flux data at a dry seasonal site (Barro Colorado Island, Panama), and at a wet rainforest site (Paracou, French Guiana). The model was able to represent size structure and carbon accumulation rates. We also evaluated the impact of the unique allocation strategy of lianas on their competitive ability. Lianas invest only a small fraction of their carbon for structural tissues when compared to trees. As a result, lianas benefit from an extra amount of available carbon, however the trade-offs of low allocation on structural tissues are not yet well understood. We are currently investigating a number of hypotheses, including the possibility for lianas to have high turnover rates for leaves and fine roots, or to have high mortality rates due to the loss of structural support when trees die. As such our model allows us to get a better understanding of the role of lianas in the tropical forest carbon cycle.

    Demography and physiology of two broad-leaved understory tropical herbs (Marantaceae) were studied in gaps and shaded understory in large-scale irrigated and control treatments during the dry season at Barro Colorado Island (BCI), Panama. Because photosynthetic acclimation potential may not predict light environments where tropical species are found, we studied a suite of physiological features to determine if they uniquely reflect the distribution of each species. Calathea inocephala and Pleiostachya pruinosa grow and reproduce in gaps, persist in shade, and have equivalent rates of leaf production. Calathea leaves survived 2 to 3 times as long as leaves of Pleiostachya and plants of Pleiostachya were 6 to 8 times more likely to die as plants of Calathea during 3.5 years of study. Pleiostachya had lowest survival in shade and when not irrigated during the dry season, while Calathea survived well in both habitats and both treatments. Pleiostachya had higher photosynthetic capacity and stomatal conductance than Calathea and acclimated to gaps by producing leaves with higher photosynthetic capacity. Calathea had lower mesophyll CO 2 concentrations than Pleiostachya. Both species had similar dark respiration rates and light compensation points, and water-use and nitrogen-use efficiencies were inversely related between species. Species showed no differences in leaf osmotic potentials at full turgor. Calathea roots were deeper and had tuberous swellings.Leaf-level assimilation and potential water loss are consistent with where these species are found, but photosynthetic acclimation to high light does not reflect both species' abilities to grow and reproduce in gaps. Pleiostachya's gap-dependent, rapid growth and reproduction require high rates of carbon gain in short-lived leaves, which can amortize their cost quickly. High rates of water loss are associated with reduced longevity during drought. Calathea's roots may confer greater capacitance, while its leaves are

    Full Text Available The study builds a model of dynamic interactions between the birth rate, the mortality rate, the population, wealth accumulation, time distribution between work, leisure and children caring, habit formation and preference change. The production technology and markets are built on the Solow growth model. We base our modeling the population dynamics on the Haavelmo population model and the Barro-Becker fertility choice model. This study takes account of habit formation and preference change. Although it is influenced by the Ramsey growth theory with time preference and habit formation, it uses Zhang’s approach to the household with habit formation and preference change. We synthesize different dynamic forces in a compact framework, using the utility function proposed by Zhang. Analytically, we focus on transitional processes as well as economic equilibrium. As the economic system is given by autonomous nonlinear differential equations, it is not easy to analyze its behavior. We simulate the model to demonstrate the existence of an equilibrium point and plot the motion of the dynamic system. We examine the effects of changes in weights given to the habit stock of children, the wife’s wage rate having negative impact on the propensity to have children, the wife weighing less the habit stock of leisure time, the wife’s habit stock of leisure time having negative impact on the husband’s propensity to use leisure time, the wife’s wage rate having negative impact on the husband’s propensity to use leisure time, woman’s human capital being improved, a rise in the total factor productivity, and the mother spending more time on each child fostering.

    The broad-leaved Korean pine mixed forest represents the typical vegetation type of the eastern mountain area in Northeast China. However, due to the interference of human activities, the natural broad-leaved Korean pine forest only distributes in some residual fragments with unequal areas in Changbai Mountains and Small Hinggan Mountains. To compare and analyze the similarities and differences of broad-leaved Korean pine mixed forests in the different areas, we established six forest plots following the field protocol of the 50 hm2 forest plot in Panama (Barro Colorado Island, BCI) in 2012 in Changbai Mountain National Nature Reserve in Jilin Province and the eastern mountain area in Liaoning Province. All free-standing plant species with DBH (diameter at breast height) > or = 1 cm were mapped, tagged and identified to species. The results showed that there were 69 woody species in the six plots, comprising 42 genera and24 families. Aceraceae was the most species-rich family in all six plots. Most species belonged to the plant type of North Temperate Zone, with a minor subtropical plant species component. The statistics of species abundance, basal area, mean DBH, and importance value showed that there were obviously dominant species in each community. The DBH distribution of all individuals showed a reversed "J" type. However, the percentage of individuals in small size-class and large size-class varied in the six communities, which indicated that these communities were at different successional stages. Ranked by the importance value, the DBH distribution of the top three species in the six plots showed four distribution types: reversed "J" distribution, reversed "L" distribution, unimodal distribution, and partial peak distribution. Spatial distribution patterns of the main species in the six plots changed differently with species and size-class, and the distribution patterns of the same species varied in the different plots.

    Land surface models that include demographic and plant hydrodynamic processes are promising tools for characterizing how different drought scenarios may affect carbon cycling of tropical forests. The Ecosystem Demography (ED2) model, now formulated with such features, was used to evaluate how different drought scenarios affect mortality patterns, functional diversity and coexistence of four plant functional types (PFTs) of tropical trees at Barro Colorado Island (BCI), Panama. The four PFTs simulated were early- versus late-successional groups subdivided into drought-tolerant versus -intolerant groups. The hydrodynamic formulation enables the four PFTs to compete mechanistically along two largely orthogonal resource gradients of water and light. The model simulations produced considerable differences in the aboveground biomass response to contrasting drying scenarios that included longer dry seasons, El Nino related droughts, and drier dry seasons. The emergent mortality dynamics reflect the physiological trade-off between water-use and carbon fixation formulated by the hydrodynamic regulation over stomatal conductance. During dry periods, the model predicts increased mortality rates of pioneer trees compared to generalists and drought-intolerant trees compared to -tolerant trees. The model also predicts that surviving cohorts in the smallest size classes of drought-intolerant trees are occasionally primed for release from competition following acute droughts. Observations at BCI showed increased mortality rates for large trees (i.e. >30 cm dbh) during the 1982 El Nino drought, but not subsequent El Nino related droughts. The causes of the elevated mortality rates are explored with the model. Coexistence of four plant functional types in the model is highly sensitive to the parameterization of stem hydraulic conductivity; but, surprisingly not very sensitive to shifts in rainfall patterns. These results demonstrate (a) that plant hydrodynamics are critical for

  10. The roots of diversity: below ground species richness and rooting distributions in a tropical forest revealed by DNA barcodes and inverse modeling.

    F Andrew Jones

    Full Text Available Plants interact with each other, nutrients, and microbial communities in soils through extensive root networks. Understanding these below ground interactions has been difficult in natural systems, particularly those with high plant species diversity where morphological identification of fine roots is difficult. We combine DNA-based root identification with a DNA barcode database and above ground stem locations in a floristically diverse lowland tropical wet forest on Barro Colorado Island, Panama, where all trees and lianas >1 cm diameter have been mapped to investigate richness patterns below ground and model rooting distributions.DNA barcode loci, particularly the cpDNA locus trnH-psba, can be used to identify fine and small coarse roots to species. We recovered 33 species of roots from 117 fragments sequenced from 12 soil cores. Despite limited sampling, we recovered a high proportion of the known species in the focal hectare, representing approximately 14% of the measured woody plant richness. This high value is emphasized by the fact that we would need to sample on average 13 m(2 at the seedling layer and 45 m(2 for woody plants >1 cm diameter to obtain the same number of species above ground. Results from inverse models parameterized with the locations and sizes of adults and the species identifications of roots and sampling locations indicates a high potential for distal underground interactions among plants.DNA barcoding techniques coupled with modeling approaches should be broadly applicable to studying root distributions in any mapped vegetation plot. We discuss the implications of our results and outline how second-generation sequencing technology and environmental sampling can be combined to increase our understanding of how root distributions influence the potential for plant interactions in natural ecosystems.

    Tropical paleoecologists use a combination of mud-water interface and modern pollen rain samples (local samples of airborne pollen) to interpret compositional changes within fossil pollen records. Taxonomic similarities between the composition of modern assemblages and fossil samples are the basis of reconstructing paleoclimates and paleoenvironments. Surface sediment samples reflect a time-averaged accumulation of pollen spanning several years or more. Due to experimental constraints, modern pollen rain samples are generally collected over shorter timeframes (1-3 years) and are therefore less likely to capture the full range of natural variability in pollen rain composition and abundance. This potentially biases paleoenvironmental interpretations based on modern pollen rain transfer functions. To determine the degree to which short-term environmental change affects the composition of the aerial pollen flux of Neotropical forests, we sampled ten years of the seasonal pollen rain from Barro Colorado Island, Panama and compared it to climatic and environmental data over the same ten-year span. We establish that the pollen rain effectively captured the strong seasonality and stratification of pollen flow within the forest canopy and that individual taxa had variable sensitivity to seasonal and annual changes in environmental conditions, manifested as changes in pollen productivity. We conclude that modern pollen rain samples capture the reproductive response of moist tropical plants to short-term environmental change, but that consequently, pollen rain-based calibrations need to include longer sampling periods (≥7 years) to reflect the full range of natural variability in the pollen output of a forest and simulate the time-averaging present in sediment samples. Our results also demonstrate that over the long-term, pollen traps placed in the forest understory are representative samples of the pollen output of both canopy and understory vegetation.

    Full Text Available Figs (Ficus sp. are often considered as keystone resources which strongly influence tropical forest ecosystems. We used long-term tree-census data to track the population dynamics of two abundant free-standing fig species, Ficus insipida and F. yoponensis, on Barro Colorado Island (BCI, a 15.6-km2 island in Lake Gatún, Panama. Vegetation cover on BCI consists of a mosaic of old growth (>400 years and maturing (about 90-150 year old secondary rainforest. Locations and conditions of fig trees have been mapped and monitored on BCI for more than 35 years (1973-2011, with a focus on the Lutz Catchment area (25 ha. The original distribution of the fig trees shortly after the construction of the Panama Canal was derived from an aerial photograph from 1927 and was compared with previous land use and forest status. The distribution of both fig species (~850 trees is restricted to secondary forest. Of the original 119 trees observed in Lutz Catchment in 1973, >70% of F. insipida and >90% of F. yoponensis had died by 2011. Observations in other areas on BCI support the trend of declining free-standing figs. We interpret the decline of these figs on BCI as a natural process within a maturing tropical lowland forest. Senescence of the fig trees appears to have been accelerated by severe droughts such as the strong El Niño event in the year 1982/83. Because figs form such an important food resource for frugivores, this shift in resource availability is likely to have cascading effects on frugivore populations.

The Northern coast of Karawang has many gulf estuaries. The existence of port, rivers, and coastal areas in Karawang emerged in the 16th century and in the 17th century as well as on written documents of Portuguese sources, and also from those documents of Vereenigde Oost India Company (VOC.  The Northern coast of Karawang were crowded by navigation of merchant ships and patrol boats. From those facts of course raises the question of where was these ports originated in Karawang. This study aimed to uncover, identify, ancient ports which was located on the northern coast of Karawang based on the written documents, archaeological remains, and its natural environment. By using surveys, interviews, the results of this research found out the significance of the ancient ports were located at the  banks of the Citarum River, the banks of the mouth of a river in Pasir Putih, and Tangkolak River estuary. Those ports function for ships as it landed ashore and also as river transportation mode. Through these ports trading took place, the spread of Islam and also served as ships patrol. By searching through the names on the written documents, as well as ecological and remains, archaeological remains were found, some of which have been investigated functions as ancient ports which was mentioned by De Barros.

    The Carajas Metallogenic Province is located in the southeastern Amazonian Craton. It has been divided in two domains, the southernmost comprises the Rio Maria region and the northernmost corresponds to Caraj region (Souza et al. 1996). The former domain is made up of Archean greenstone sequences (2,97 Ga), TTG (2,9 Ga) and calc-alkaline granitoids (2,87 Ga) (Macambira and Lafon 1995, Leite et al. 1999, Althoff et al. 2000). The Carajas block is constituted of minor mafic granulites (3,00 Ga) and quartzofeldspathic gneisses (2,81 Ga), metavolcanosedimentary sequences (2,76 Ga) and granites (2,76 to 2,56 Ga) (Machado et al. 1991; Huhn et al. 1999, Pidgeon et al. 2000). Widespread anorogenic A-type granites are found in both areas (Docegeo 1988; Dall'Agnol et al. 1994). In the last two decades several authors (Lindenamyer et al. 1994, Barros and Barbey 1998, Huhn et al. 1999 and others) have emphasized the role of the Archean granite magmatism in the tectonicthermal evolution in the Carajas Province. In this paper we discuss the tectonic significance of the Pb- Pb and U-Pb ages obtained in some granitoids from the Carajas region. The Estrela Granite Complex and the granitoids located to the north of Parauapebas were dated by Pb- Pb evaporation zircon method (cf. Kober 1987). Data are presented considering 2σ ∼ . The Pb corrections have been done in the basis of the evolution model of Pb in double stage (cf. Stacey and Kramers 1975). U-Pb zircon method (cf. Krogh 1973, Stacey and Kramers 1975, Parrish 1987, Ludwuig 1999), recently put on routine in the Para-Iso laboratories, was employed to date the granite from the Serra do Rabo area.

Contrariando estas teses, procura-se aqui resgatar a importância da política econômica dentro da conjuntura, mostrando que a mesma possui uma racionalidade, a qual inclusive se manifesta na constante troca de ministros da área econômica. Para tanto, recorre-se ao modelo de credibilidade de Barro e ao conceito de legitimidade de Max Weber para reconstituir os impasses do governo e seus reflexos na condução da política econômica.Most of the literature on the Goulart Administration relates the low growth rates and rise of inflation in the period to structural reasons, while the economic policy is usually viewed as erratic and hesitant. In opposition to these theses, we attempt to restore the importance of the economic policy inside the conjuncture, showing its rationality which is manifested in the constant changing of ministers in the economic area. In order to do so, we use Barro’s credibility model and Max Weber’s legitimacy concept to re-establish the predicaments of the Administration and their reflections on the guidance of the economic policy.

The goal of glaucoma treatment is to reduce the intraocular pressure to a level that prevents or minimizes the progressive loss of vision. The current standard of management for the newly diagnosed primary open angle glaucoma (PAOG patient is to start topical medication. Available topical medications include: beta-adrenergic antagonists, alpha-adrenergic agonists, carbonic anhydraze inhibitors, prostaglandin analogues and miotics. In some patients, IOP is not adequately controlled by monotherapy. In those refractory patients, where more efficacy is required, shifting to another medication or adding a second medication is indicated. The complimentary action between two drugs serves as the basis for combination medications. One avenue of delivering a second medication is through a fixed combination medication that has the advantage of providing two medicines within one drop. Bimatoprost/timolol represents a new fixed combination which is clinically and statistically more effective than either of its active constituents for patients with refractory glaucoma. As regard the safety of the combination, there were no signs or symptoms of intolerance and the incidence of conjunctival hyperemia was clinically and statistically significantly less than each of the two components separately. Bimatoprost/timolol fixed combination offers cost and time savings, which may enhance compliance; also reducing the amount of preservative applied to the eye, will improve

    Witches' broom disease (WBD) caused by the fungus Moniliophthora perniciosa is responsible for considerable economic losses for cacao producers. One of the ways to combat WBD is to plant resistant cultivars. Resistance may be governed by a few genetic factors, mainly found in wild germplasm. We developed a dense genetic linkage map with a length of 852.8 cM that contains 3,526 SNPs and is based on the MP01 mapping population, which counts 459 trees from a cross between the resistant 'TSH 1188' and the tolerant 'CCN 51' at the Mars Center for Cocoa Science in Barro Preto, Bahia, Brazil. Seven quantitative trait loci (QTL) that are associated with WBD were identified on five different chromosomes using a multi-trait QTL analysis for outbreeders. Phasing of the haplotypes at the major QTL region on chromosome IX on a diversity panel of genotypes clearly indicates that the major resistance locus comes from a well-known source of WBD resistance, the clone 'SCAVINA 6'. Various potential candidate genes identified within all QTL may be involved in different steps leading to disease resistance. Preliminary expression data indicate that at least three of these candidate genes may play a role during the first 12 h after infection, with clear differences between 'CCN 51' and 'TSH 1188'. We combined the information from a large mapping population with very distinct parents that segregate for WBD, a dense set of mapped markers, rigorous phenotyping capabilities and the availability of a sequenced genome to identify several genomic regions that are involved in WBD resistance. We also identified a novel source of resistance that most likely comes from the 'CCN 51' parent. Thanks to the large population size of the MP01 population, we were able to pick up QTL and markers with relatively small effects that can contribute to the creation and selection of more tolerant/resistant plant material.

  4. Post-dispersal predation and scatterhoarding of Dipteryx panamensis (Papilionaceae) seeds by rodents in Panama.

    In tropical rain forests of Central America, the canopy tree Dipteryx panamensis (Papilionaceae) fruits when overall fruit biomass is low for mammals. Flying and arboreal consumers feed on D. panamensis and drop seeds under the parent or disperse them farther away. Seeds on the ground attract many vertebrate seed-eaters, some of them potential secondary seed dispersers. The fate of seeds artificially distributed to simulate bat dispersal was studied in relation to fruitfall periodicity and the visiting frequency of diurnal rodents at Barro Colorado Island (BCI), Panama. The frequency of visits by agoutis is very high at the beginning of fruitfall, but in the area close (50 m) away (Dipteryx-poor and Gustavia-rich area). Squirrels were usually observed in the Dipteryx-rich area. Along with intense post-dispersal seed predation by rodents in the Dipteryx-rich area, a significant proportion of seeds were cached by rodents in the Dipteryx-poor area. Post-dispersal seed predation rate was inversely related to hoarding rate. A significantly greater proportion of seeds was cached in March, especially more than 100 m from the nearest fruiting tree. This correlates with the mid-fruiting period, i.e. during the height of D. panamensis fruiting, when rodents seem to be temporarily satiated with the food supply at parent trees. Hoarding remained high toward April, i.e. late in the fruiting season of D. panamensis. Low survival of scatterhoarded seeds suggests that the alternative food supply over the animal's home-ranges in May-June 1990 was too low to promote survival of cached seeds. Seedlings are assumed to establish in the less-used area of the rodents' home-range when overall food supply is sufficient to satiate post-dispersal predators.

In the train level mixed testing scheme, the components are tested in a non-staggered way within the same train, but the components are tested in a staggered way between the trains. The alternate periodic testing scheme indicates that all components in the same CCCG are tested in a non-staggered way during the planned maintenance period, but they are tested in a staggered way during normal plant operation. Since the CCF probabilities are dependent on the testing schemes such as staggered testing or non-staggered testing, CCF estimators have two kinds of formulas in accordance with the testing schemes. Thus, there are general formulas to estimate the CCF probability on the staggered testing scheme and non-staggered testing scheme. However, in real plant operation, there are many CCCGs with specific mixed testing schemes. Recently, Barros () and Kang () proposed a CCF factor estimation method to reflect the alternate periodic testing scheme and the train level mixed testing scheme. In this paper, a general formula which is applicable to both the alternate periodic testing scheme and the train level mixed testing scheme was derived.

    We developed a statistical framework to quantify mortality rates in canopy trees observed using time series from high-resolution remote sensing. By timing the acquisition of remote sensing data with synchronous annual flowering in the canopy tree species Handroanthus guayacan, we made 2,596 unique detections of 1,006 individual adult trees within 18,883 observation attempts on Barro Colorado Island, Panama (BCI) during an 11-yr period. There were 1,057 observation attempts that resulted in missing data due to cloud cover or incomplete spatial coverage. Using the fraction of 123 individuals from an independent field sample that were detected by satellite data (109 individuals, 88.6%), we estimate that the adult population for this species on BCI was 1,135 individuals. We used a Bayesian state-space model that explicitly accounted for the probability of tree detection and missing observations to compute an annual adult mortality rate of 0.2%·yr -1 (SE = 0.1, 95% CI = 0.06-0.45). An independent estimate of the adult mortality rate from 260 field-checked trees closely matched the landscape-scale estimate (0.33%·yr -1 , SE = 0.16, 95% CI = 0.12-0.74). Our proof-of-concept study shows that one can remotely estimate adult mortality rates for canopy tree species precisely in the presence of variable detection and missing observations. © 2017 by the Ecological Society of America.

Patients and methods: A cross-sectional study was conducted on 208 adult patients with upper gastrointestinal symptoms. Gastric biopsy specimens were obtained from each patient for molecular DNA and histological examination. Patients were genotyped for VDR gene polymorphisms using polymerase chain reaction and restriction fragment length polymorphism analysis. Results: The allelic and genotypic distribution analyses of the FokI, ApaI and TaqI polymorphisms of the VDR gene did not show distribution differences between H. pylori-positive and -negative groups. The genotype distribution observed for polymorphism BsmI deviated significantly from what was expected in a Hardy–Weinberg equilibrium test in the H. pylori-positive group (X2=29.048, p<0.001. The distribution of BsmI genotypes differed significantly between the H. pylori-negative and H. pylori-positive groups (p=0.0034, where the frequency of the bb genotype increased among H. pylori-positive individuals compared with those without infection (63.25% versus 50.55%, respectively. Conversely, the H. pylori-negative group showed a Bb frequency that was 20.27% higher than in the infected group. Conclusion: We identified a possible association between the BsmI polymorphism and infection by H. pylori. However, further research is required to clarify this relationship.

    Triodus is a well-known genus of Xenacanthiformes, previously recorded from the late Bashkirian (Lower Pennsylvanian, Carboniferous) to the middle Artinskian (Cisuralian, Permian), mainly from Laurasian deposits (Europe and USA). For the first time, this genus is recorded from the Western Gondwana, based on isolated teeth that are referred to Triodus richterae sp. nov. The new species were found associated with other shark teeth (another xenacanthiforms and a possible euselachian), palaeoniscoid teeth and scales, labyrinthodont teeth, tetrapod bony remains, macroscopic charcoal and leaf fragments. This fossil assemblage was collected in a conglomerate layer from the Barro Alto site (São Gabriel municipality, Rio Grande do Sul State, Brazil), with an estimated Capitanian age, from the Morro Pelado Member, Rio do Rasto Formation, Paraná Basin. The new species has teeth with an almost oval base and the aboral surface has a smooth concavity and a rounded to horseshoe-shaped basal tubercle. The coronal surface of these teeth has a tricuspid crown, a rhomboid-shaped coronal button with rounded edges with a lingually directed shaft and some oral foramina predominantly situated at the lingual margin of the base and flanking the lingual shaft. The lateral cusps bear a variable number of non-branching vertical cristae, distributed from the apex to their proximal portion, making the transversal section of these cusps asterisk-shaped. Microstructurally, these teeth have both base and cusps composed of orthodentine with an opened pulp cavity. T. richterae sp. nov. represents the youngest species of Triodus, considering it comes from Capitanian (late Guadalupian) beds, which are at least 15 Ma younger than T. kraetschmeri, the previously youngest species of this genus. The depositional interpretation, as well as the fossil assemblage in the type locality of the new species and of the Rio do Rasto Formation as a whole, indicates another freshwater record for xenacanthid sharks.

    Full Text Available The ongoing accumulation of industrial waste speaks to the need to seek cost-effective disposal methods. Brick manufacture would appear to be particularly promising in this regard. The present study analyzes the possibility of recycling the sludge generated in porcelain tile polishing, as well as coal, steel and municipal incinerator ash to make a special type of facing brick whose properties readily accommodate a full analysis of all the problems deriving from the incorporation of residue in its manufacture. Physical-chemical, mechanical and structural analyses were performed on bricks made with varying percentages of the different types of waste considered. This first paper reports the results of the physical arid technological characterization of the products; the second part of the research will address their chemical, mechanical and structural properties.

    El continuo aumento de la cantidad de residuos (desechos que se generan en los procesos industriales induce a buscar nuevos métodos alternativos a la disposición final que sean altamente eficientes y a bajo costo. La industria manufac turera de ladrillos resulta muy prometedora desde este punto de vista. En este trabajo ha sido investigada la posibilidad de usar distintos residuos industriales, entre ellos barros de pulido del gres porcelánico. cenizas de carbón, cenizas de acerías y de incinerador municipal para la fabricación de ladrillos de exteriores. Fueron analizados los problemas que podrían derivar al introducir estos residuos en la pasta. En particular, en esta primera parte del trabajo se muestran los resultados derivados de la introducción de los residuos considerados, en distintos porcentajes, sobre las propiedades físicas y tecnológicas del producto final. En la segunda parte se desarrollarán los efectos causados sobre las propiedades químicas, mecánicas y microestructurales.

    Full Text Available Modeling sub-canopy elevation is an important step in the processing of waveform lidar data to measure three dimensional forest structure. Here, we present a methodology based on high resolution discrete-return lidar (DRL to correct the ground elevation derived from large-footprint Laser Vegetation Imaging Sensor (LVIS and to improve measurement of forest structure. We use data acquired over Barro Colorado Island, Panama by LVIS large-footprint lidar (LFL in 1998 and DRL in 2009. The study found an average vertical difference of 28.7 cm between 98,040 LVIS last-return points and the discrete-return lidar ground surface across the island. The majority (82.3% of all LVIS points matched discrete return elevations to 2 m or less. Using a multi-step process, the LVIS last-return data is filtered using an iterative approach, expanding window filter to identify outlier points which are not part of the ground surface, as well as applying vertical corrections based on terrain slope within the individual LVIS footprints. The results of the experiment demonstrate that LFL ground surfaces can be effectively filtered using methods adapted from discrete-return lidar point filtering, reducing the average vertical error by 15 cm and reducing the variance in LVIS last-return data by 70 cm. The filters also reduced the largest vertical estimations caused by sensor saturation in the upper reaches of the forest canopy by 14.35 m, which improve forest canopy structure measurement by increasing accuracy in the sub-canopy digital elevation model.

    Full Text Available CONTEXT: Misoprostol, a synthetic E1 methyl analog prostaglandin, is at present receiving attention as a cervical modifier and labor induction agent. However, there is still a need for better determination of its safety and effectiveness. OBJECTIVE: To compare intravaginal misoprostol versus intravenous oxytocin for cervical ripening and labor induction in pregnant women with unripe cervices. DESIGN: Randomized controlled trial. SETTING: The study was performed at the Leonor Mendes de Barros Maternity Hospital between November 1998 and December 2000. PARTICIPANTS: 210 pregnant women with intact membranes and indication for labor induction were selected. PROCEDURES: The women randomly received 25 µg of vaginal misoprostol every 4 hours, not exceeding 8 doses (105 women, or oxytocin in a continuous infusion (105 women. MAIN MEASUREMENTS: The main parameters measured were: latent period, time from induction to vaginal delivery, delivery route, occurrence of vaginal delivery with time, occurrence of uterine tonus alterations, hypoxia and neonatal morbidity. To verify the statistical significance of the differences between the groups, the chi-squared, Student t and log-rank tests were used. RESULTS: There were no significant differences between the groups concerning conditions for labor induction, age, parity, race, marital status, family income, initial Bishop Index and number of prenatal visits. The cesarean section rate, latent period and period from induction to vaginal delivery were significantly lower for the misoprostol group. With regard to uterine tonus alterations, tachysystole was significantly more common in the misoprostol group. However, there was no difference in hypoxia and neonatal morbidity between the groups. CONCLUSION: 25 µg of misoprostol used vaginally every 4 hours is safer and more efficient for cervical ripening and labor induction than oxytocin.

    Forests play an important role in the exchange of radiatively important gases with the atmosphere. Previous studies have shown that in both temperate and tropical wetland forests tree stems are significant sources of methane (CH4), yet little is known about trace greenhouse gas dynamics in 'upland' free-draining soils that dominate global forested areas. We examined trace gas (CH4 and N2O) fluxes from both soils and tree stems in lowland tropical forest on free-draining soils in Panama, Central America (Barro Colorado Nature Monument), in the Amazon (Cunia) and from a deciduous woodland in the United Kingdom (Wytham, Oxfordshire). In Panama, fluxes were sampled over the dry to wet season transition (March-August) in 2014 and November 2015. In Cunia, we measured mature and young tree fluxes in a single campaign during 2013 from two 20 x 30 m plots. CH4 and N2O flux was measured from the stem between 20 and 140 cm above the forest floor. Soil fluxes were measured 1 m away from each tree under investigation. Temperate fluxes were sampled at Wytham Woods, Oxfordshire, over 12 months from February 2015 to January 2016. Tree stem samples were collected via syringe from temporary chambers strapped to the trees and soil fluxes were sampled from installed collars. We found that trees behaved as both sources (near the tree base) and sinks (higher up the tree stem) of methane across Panamanian and UK sites, however, this pattern was only apparent in a subset of trees in the Amazon where the dominant process was stem CH4 uptake for the majority of trees. We synthesise these results and those of our N2O measurements and report the consequences for ecosystem budgets of these gases.

  17. Effects of phosphorus and nitrogen additions on tropical soil microbial activity in the context of experimental warming

    Soil warming is generally predicted to increase microbial mineralization rates and accelerate soil C losses which could establish a positive feedback to climatic warming. Tropical rain forests account for a third of global soil C, yet the responseto of tropical soil C a warming climate remains poorly understood. Despite predictions of soil C losses, decomposition of soil organic matter (SOM) in tropical soils may be constrained by several factors including microbial nutrient deficiencies. We performed an incubation experiment in conjunction with an in-situ soil warming experiment in a lowland tropical forest on Barro Colorado Island, Panama, to measure microbial response to two key nutrient additions in shallow (0-10cm) and deep (50-100 cm) soils. We compared the response of lowland tropical soils to montane tropical soils, predicting that lowland soils would display the strongest response to phosphorus additions. Soils were treated with either carbon alone (C), nitrogen (CN), phosphorus (CP) or nitrogen and phosphorus combined (CNP). Carbon dioxide (CO2) production was measured by NaOH capture and titrimetric analysis for 10 days. Cumulative CO2 production in montane soils increased significantly with all additions, suggesting these soils are characterized by a general microbial nutrient deficiency. The cumulative amount of C respired in deep soils from the lowland site increased significantly with CP and CNP additions, suggesting that microbial processes in deep lowland tropical soils are phosphorus-limited. These results support the current understanding that lowland tropical forests are growing on highly weathered, phosphorus-deplete soils, and provide novel insight that deep tropical SOM may be stabilized by a lack of biologically-available phosphorus. Further, this data suggests tropical soil C losses under elevated temperature may be limited by a strong microbial phosphorus deficiency.

    Figs (Ficus sp.) are often considered as keystone resources which strongly influence tropical forest ecosystems. We used long-term tree-census data to track the population dynamics of two abundant free-standing fig species, Ficus insipida and F. yoponensis, on Barro Colorado Island (BCI), a 15.6-km2 island in Lake Gatún, Panama. Vegetation cover on BCI consists of a mosaic of old growth (>400 years) and maturing (about 90–150 year old) secondary rainforest. Locations and conditions of fig trees have been mapped and monitored on BCI for more than 35 years (1973–2011), with a focus on the Lutz Catchment area (25 ha). The original distribution of the fig trees shortly after the construction of the Panama Canal was derived from an aerial photograph from 1927 and was compared with previous land use and forest status. The distribution of both fig species (~850 trees) is restricted to secondary forest. Of the original 119 trees observed in Lutz Catchment in 1973, >70% of F. insipida and >90% of F. yoponensis had died by 2011. Observations in other areas on BCI support the trend of declining free-standing figs. We interpret the decline of these figs on BCI as a natural process within a maturing tropical lowland forest. Senescence of the fig trees appears to have been accelerated by severe droughts such as the strong El Niño event in the year 1982/83. Because figs form such an important food resource for frugivores, this shift in resource availability is likely to have cascading effects on frugivore populations.

  20. Varying influence of environmental gradients on vegetation patterns across biomes

    Environmental gradients, like elevation, slope, aspect, and soil properties, filter vegetation types at the local scale. These `environmental filters' create conditions that are conducive to the success or failure of different plant types, influencing landscape-scale heterogeneity in taxonomic diversity, functional diversity, biomass accumulation, greenness, and more. Niche-based models implicitly assume that environmental filtering is the dominant process controlling plant distributions. While environmental filtering is a well understood process, its importance relative to other drivers of heterogeneity, like disturbance, human impacts, and plant-animal interactions, remains unknown and likely varies between biomes. Here we synthesize results from several studies using data from the Carnegie Airborne Observatory - a fused LiDAR and imaging spectroscopy system - that mapped a vegetation patterns in multiple biomes and associated these with environmental gradients. The study sites range from Panama to California, and the patterns range from aboveground carbon to foliar chemistry. We show that at fine spatial scales environmental filtering is a strong predictor of aboveground biomass in a dry system (Jasper Ridge Biological Preserve, California - Dahlin et al 2012) but a weak predictor of plant functional traits in that same system (Dahlin et al 2014), a weak predictor of aboveground carbon in the tropics (Barro Colorado Island, Panama - Mascaro et al 2011; Osa Peninsula, Costa Rica - Taylor et al 2015), and a weak predictor of greenness (NDVI) in a disturbed dry system (Santa Cruz Island, California - Dahlin et al 2014). Collectively, these results suggest that while environmental filtering is an important driver of landscape-scale heterogeneity, it is not the only, or often even the most important, driver for many of these systems and patterns.

    Chronic obstructive pulmonary disease (COPD) is the fourth leading cause of death worldwide. The study aimed to determine and compare the prevalence of COPD in the general population aged 45-74 years old according to fixed ratio and lower limit of normal (LLN) thresholds in four cities in the Southern Cone of Latin America. The Pulmonary Risk in South America (PRISA) study used a 4-stage stratified sampling method to select 5814 participants from 4 cities in the Southern Cone of Latin America (Bariloche and Marcos Paz, Argentina; Temuco, Chile; and Pando-Barros Blancos, Uruguay). Data on demographic information, medical history, risk factors, pre-bronchodilator and post-bronchodilator spirometry were obtained using a standard protocol. According to GOLD, COPD was defined as a post-bronchodilator ratio of forced expiratory volume in one second (FEV1) over forced vital capacity (FVC) less than 70%. The LLN threshold was defined as the lower fifth percentile for predicted FEV1/FVC, and was evaluated as an alternative COPD definition. Overall COPD prevalence was 9.3% (95% CI 8.4, 10.2%), and men had a higher prevalence [11.8% (95% CI 10.3, 13.3%)] than women [7.3% (95% CI 6.2, 8.3%)] with the fixed ratio. Overall COPD prevalence using LLN was 4.7% (95% CI 4.1, 5.3%), higher in men: 5.8% (95% CI 4.7, 6.8%) than women: 3.9% (95% CI 3.1, 4.7%). COPD prevalence was significantly higher among those who were older, had Latin America.

    Cardiovascular disease is a major cause of death, and its mortality is increasing in Latin America. However, population-based data on cardiovascular disease risk factors are sparse in these countries. A total of 7524 men and women, aged 35 to 74 years old, were recruited between February 2010 and December 2011 from randomly selected samples in 4 cities (Bariloche and Marcos Paz, Argentina; Temuco, Chile; and Pando-Barros Blancos, Uruguay) in the Southern Cone of Latin America. Cardiovascular risk factors were measured using standard methods by trained and certified observers. Approximately 85.5% of adults ate less than five servings of fruit or vegetables per day, 35.2% engaged in low physical activity, and 29.7% currently smoked cigarettes. The prevalences of obesity, central obesity, hypertension, chronic kidney disease, dyslipidemia, diabetes, and metabolic syndrome were 35.7%, 52.9%, 40.8%, 2.0%, 58.4%, 12.4%, and 37.4%, respectively. The proportion of individuals with ≥3 cardiovascular risk factors, including low intake of fruit and vegetables, low physical activity, current cigarette smoking, obesity or central obesity, hypertension, chronic kidney disease, dyslipidemia, and diabetes, was 68.3%, and the proportion of individuals with ≥3 cardiometabolic risk factors, including obesity or central obesity, hypertension, chronic kidney disease, dyslipidemia, and diabetes, was 22.9%. Cardiovascular disease risk factors are highly prevalent in the general population in the Southern Cone of Latin America. These data suggest that national efforts on the prevention, treatment, and control of cardiovascular risk factors should be a public health priority in the Southern Cone of Latin America.

    Hypertension is the leading global preventable risk factor for premature death. While hypertension prevalence has been declining in high-income countries, it has increased continuously in low- and middle-income countries. We conducted a cross-sectional survey in 7,524 women and men aged 35-74 years from randomly selected samples in 4 cities (Bariloche and Marcos Paz, Argentina; Temuco, Chile; and Pando-Barros Blancos, Uruguay) in 2010-2011. Three blood pressure (BP) measurements were obtained by trained observers using a standard mercury sphygmomanometer. Hypertension was defined as a mean systolic BP ≥140mm Hg and/or diastolic BP ≥90mm Hg and/or use of antihypertensive medications. An estimated 42.5% of the study population (46.6% of men and 38.7% of women) had hypertension and an estimated 32.5% (36.0% of men and 29.4% of women) had prehypertension. Approximately 63.0% of adults with hypertension (52.5% of men and 74.3% of women) were aware of their disease condition, 48.7% (36.1% of men and 62.1% of women) were taking prescribed medications to lower their BP, and only 21.1% of all hypertensive patients (13.8% of men and 28.9% of women) and 43.3% of treated hypertensive patients (38.1% of men and 46.5% of women) achieved BP control. This study indicates that the prevalence of hypertension is high while awareness, treatment, and control are low in the general population in the Southern Cone of Latin America. These data call for bold actions at regional and national levels to implement effective, practical, and sustainable intervention programs aimed to improve hypertension prevention, detection, and control.

    Beginning in the lower Triassic, intracratonic, basins are formed in the Westem Pampean Ranges region, San Juan province, Argentina. One of these basins, the Marayes-El Carrizal basin, extends in an approximate NNW-SSE direction along the entire western edge of the La Huerta range, between latitudes 31 o 15' - 31 o 48' South and longitudes 67 o 12'-67 o 3O' West. According to Ramos (1993), the initial facies of the synrift deposits (Marayes Group) that fill the mentioned basin, are associated with the emplacement of basaltic flows and sills, part of the residual activity of the Choiyoi Group. Bossi (1975), analyzes in detail the stratigraphy of the Marayes Group. lt consists of an interstratified sequence of continental clastic sediments of mid to upper Triassic age (based on paleontological and palinological evidences) including, in ascending stratigraphic order, the Esquina Colorada, Carrizal and Quebrada del Barro Formations. The only igneous component in this sequence is a basaltic body, referred to as Marayes Viejo Basalt (BMV), located in the area known as Marayes Viejo in the extreme southem part of the La Huerta range, at approximately 31 o 25' South Latitude and 67 o 22' West Longitude. He describes the body as an 'elongated oval shaped dike that intrudes the Esquina Colorada Formation and whose age is uncertain because is an intrusive body'. More recently, Castro de Machuca et al. (1998), identify in the same area a small hypabisal body of andesitic composition, the Marayes Viejo Porphry (PNW), whose radiometric age (259±3 Ma) permits assigning to the Neopaleozoic. The absolute age of the BMV presentes in this work, confirms the spatial relationships observed between the different lithostratigraphic units, and supports the conclusion that the magmatic activity in the area is initiated in the Neopaleozoic, prior to the formation and filling of the Marayes-El Carrizal basin (au)

    Full Text Available Toxocara species are most common roundworms of Canidae and Felidae. Human toxocariasis develops by ingesting of embryonated eggs in contaminated soil. There is no previous report of Toxocara contamination in the soil samples from the public areas in Bangkok. For this reason our study have been carried out to examine the frequency of Toxocara eggs in public yards in Bangkok, Thailand. A total of 175 sand and clay samples were collected and examined for parasite eggs. According to this study, Toxocara eggs were detected from 10 (5.71% of 175 soil samples. The high rate of contamination in this study implies the importance of the control of this possible zoonotic disease: control of abandon of dogs and cats, is still necessary.Espécies de Toxocara são os ascarídeos mais comuns de canídeos e felídeos. A toxocaríase humana se desenvolve através da ingestão de ovos embrionados presentes no solo. Não existe nenhum relato prévio da contaminação de Toxocara em amostras de solo de áreas públicas em Bangkok. Devido a isso, nosso estudo visou o exame da freqüência de ovos de Toxocara em Parques públicos em Bangkok, Tailândia.

    In this tutorial the main concepts and applications of experimental design in chemistry will be explained. Unfortunately, nowadays experimental design is not as known and applied as it should be, and many papers can be found in which the "optimization" of a procedure is performed one variable at a time. Goal of this paper is to show the real advantages in terms of reduced experimental effort and of increased quality of information that can be obtained if this approach is followed. To do that, three real examples will be shown. Rather than on the mathematical aspects, this paper will focus on the mental attitude required by experimental design. The readers being interested to deepen their knowledge of the mathematical and algorithmical part can find very good books and tutorials in the references [G.E.P. Box, W.G. Hunter, J.S.

    In the last five years, slaughterhouses in Galicia have been producing more than 350,000 tonnes of carcass per year (Ministry of Environmental and Marine and Rural Media (MARM), 2013). The main environmental problems derived from this economic activity are the high consumption of water, the generation of waste water with a high organic load and the intensive use of energy (electricity and fuel) (European Commission, 2005). In this region of Spain, there are seventy-one slaughterhouses but only 10 to 15% of them have a carcass production capacity exceeding 50 tonnes per day (Casares et al., 2006), consequently needing an environmental permit according to the requirements set by the IPPC (Integrated Pollution Prevention and Control) Directive (European Commission, 2008). The slaughterhouses can be specialized in one livestock type, such as pigs, cattle, sheep, goats or rabbits, or they can be polyvalent. In 2009, the most important meat productions were from porcine, poultry and bovine, as they represented 96% of total production in Spain (AICE, 2011). This paper presents a general view of this important sub-sector (according to the Spanish CNAE, National Classification of Economical Activities) of the food and drinking industry in Galicia. The work considers general information about the activity, an exhaustive description of the industrial process (including preliminary operations, processing, final and auxiliary operations), environmental aspects about consumption and emission levels, and finally a proposal of technique candidates to be BAT (best available techniques) for each process stage. This structure has permitted to obtain an inventory of pollution prevention and control techniques, as well as qualitative data of incomes and outcomes of consumptions and emissions respectively. The methodology, which has already been used in previous works (Barros et al., 2008), has been proved to be appropriate to optimize the process considering environmental factors as

    Autism Spectrum Disorder (ASD) is a neurodevelopmental disorder characterized by impairments in social interaction and repetitive patterns of behavior, which can lead to deficits in adaptive behavior. In this study, a serious game was developed to train individuals with ASD for an important type of outdoor activity, which is the use of buses as a means of transportation. The aim of this study was to develop a serious game that defines a "safe environment" where the players became familiar with the process of taking a bus and to validate if it could be used effectively to teach bus-taking routines and adaptive procedures to individuals with ASD. In the game, players were placed in a three-dimensional city and were submitted to a set of tasks that involved taking buses to reach specific destinations. Participants with ASD (n=10) underwent between 1 to 3 training sessions. Participants with typical development (n=10) were also included in this study for comparison purposes and received 1 control session. We found a statistically significant increase in the measures of knowledge of the process of riding a bus, a reduction in the electrodermal activity (a metric of anxiety) measured inside the bus environments, and a high success rate of their application within the game (93.8%). The developed game proved to be potentially useful in the context of emerging immersive virtual reality technologies, of which use in therapies and serious games is still in its infancy. Our findings suggest that serious games, using these technologies, can be used effectively in helping people with ASD become more independent in outdoor activities, specifically regarding the use of buses for transportation. ©Marco Simões, Miguel Bernardes, Fernando Barros, Miguel Castelo-Branco.

    Full Text Available Cystic fibrosis (CF is the most common genetic disease among Caucasians and is rare among sub-Saharan Africans. The Brazilian population is not ethnically homogeneous but it is the result of three-way ethnic admixture of Europeans, Africans and Amerindians in varying proportions, depending on the region. In the present study, we investigated 33 patients who had been diagnosed and are currently under treatment for CF at the University Hospital João de Barros Barreto, Belém, Pará State. The molecular analysis for G542X, G551D and R553X mutations was performed by PCR followed by RFLP using BstNI, HincII and MboI, respectively, in polyacrylamide gel eletrophoresis and stained with AgNO3. ThedeltaF508 mutation (a deletion of 3 bp was only analyzed by polyacrylamide gel electrophoresis and stained with AgNO3. Each sample was analyzed for regions of interest in the CFTR gene using amplified by PCR and specific primers. The deltaF508 and G551D mutations presented frequencies of 22.7 and 3%, respectively. In 74.3% of the remaining patients, none of the mutations investigated was found. The present study characterized in a sample of patients with an established clinical diagnosis of CF (asthma, repeated bronchopneumonia, disorders of nutritional status, etc. the most frequent mutation ( deltaF508 in the North region of Brazil and is also the first report of the G551D mutation. In spite of the wide spectrum of CF mutations and the heterogeneous ethnic origin of the Amazon population, the molecular diagnosis is a helpful additional tool for the diagnosis and treatment of CF patients.

    Full Text Available Former Alberta premier Peter Lougheed is celebrated for his defence of the province and Western Canada during the energy wars of the 1970s, and deservedly so. Prime Minister Pierre Trudeau was a formidable opponent. He was able and willing to use the full arsenal of federal powers to redirect soaring western energy revenues away from Alberta to Ottawa. For those of us in Western Canada, it is unpleasant to imagine what the outcome of this struggle would have been if a lesser man than Peter Lougheed had been at Alberta’s helm. But there is another aspect of the Lougheed legacy that is less remembered because it is less celebrated—also deservedly so. These were Lougheed’s ambitious economic diversification projects. Between 1973 and 1993 (when Ralph Klein became premier, the Lougheed-Getty “forced-growth” economic diversification projects are conservatively estimated to have cost Albertans $2.2 billion. While former premier Don Getty got most the blame for these losses (as many occurred during his watch, most of these programs began earlier. Lougheed’s push for government-led diversification of the Alberta economy was a policy hallmark of his 1971 electoral breakthrough, and marked a sharp break from three decades of Social Credit laissez-faire policies. The Lougheed-Getty diversification fiascos are of more than just historical interest. While the subsequent Progressive Conservative (PC regime of Premier Ralph Klein (1993–2006 followed an explicit philosophy of “government is not in the business of business,” the more recent Stelmach (2006–11 and Redford (2011-14 governments have not.

    A fundamental unanswered question for global change ecology is to determine the vulnerability of tropical forests to climate change, particularly with increasing intensity and frequency of drought events. This question, despite its apparent simplicity, remains difficult for earth system models to answer, and is controversial in remote sensing literature. Here, we leverage unique multi-scale remote sensing measurements (from leaf to crown) in conjunction with four-continuous-year (2013-2017) eddy covariance measurements of ecosystem carbon fluxes in a tropical forest in Panama to revisit this question. We hypothesize that drought impacts tropical forest photosynthesis through variation in abiotic drivers (solar radiation, diffuse light fraction, and vapor pressure deficit) that interact with physiological traits that govern photosynthesis, and biotic variation in ecosystem photosynthetic capacity associated with changes in the traits themselves. Our study site, located in a seasonal tropical forest on Barro Colorado Island (BCI), Panama, experienced a significant drought in 2015. Local eddy covariance derived photosynthesis shows an abrupt increase during the drought year. Our specific goal here is to assess the relative impact of abiotic and biotic drivers of such photosynthesis response to interannual drought. To this goal, we derived abiotic drivers from eddy tower-based meteorological measurements. We will derive the biotic drivers using a recently developed leaf demography-ontogeny model, where ecosystem photosynthetic capacity can be described as the product of field measured, age-dependent leaf photosynthetic capacity and local tower-camera derived ecosystem-scale inter-annual variability in leaf age demography of the same time period (2013-2017). Lastly, we will use a process-based model to assess the separate and joint effects of abiotic and biotic drivers on eddy covariance derive photosynthetic interannual variability. Collectively, this novel multi

    We are applying machine learning (ML) techniques to continuous acoustic emission (AE) data from laboratory earthquake experiments. Our goal is to apply explicit ML methods to this acoustic datathe AE in order to infer frictional properties of a laboratory fault. The experiment is a double direct shear apparatus comprised of fault blocks surrounding fault gouge comprised of glass beads or quartz powder. Fault characteristics are recorded, including shear stress, applied load (bulk friction = shear stress/normal load) and shear velocity. The raw acoustic signal is continuously recorded. We rely on explicit decision tree approaches (Random Forest and Gradient Boosted Trees) that allow us to identify important features linked to the fault friction. A training procedure that employs both the AE and the recorded shear stress from the experiment is first conducted. Then, testing takes place on data the algorithm has never seen before, using only the continuous AE signal. We find that these methods provide rich information regarding frictional processes during slip (Rouet-Leduc et al., 2017a; Hulbert et al., 2017). In addition, similar machine learning approaches predict failure times, as well as slip magnitudes in some cases. We find that these methods work for both stick slip and slow slip experiments, for periodic slip and for aperiodic slip. We also derive a fundamental relationship between the AE and the friction describing the frictional behavior of any earthquake slip cycle in a given experiment (Rouet-Leduc et al., 2017b). Our goal is to ultimately scale these approaches to Earth geophysical data to probe fault friction. References Rouet-Leduc, B., C. Hulbert, N. Lubbers, K. Barros, C. Humphreys and P. A.

    In the central region of Brazil, Tocantins (TO) province, the distribution of tectonic stresses are not well known; there is only a measurement of stress and no data from focal mechanisms.To understand the processes that occur during an earthquake, it is necessary to have a precise knowledge of the earthquake source parameters. This work shows that the focal mechanism of an earthquake can be obtained in reliable way using only information contained in its band-pass-filtered waveforms registered at a few stations.The inversion for the focal mechanism was made using the package ISOLA (Zahradnik et al., 2005, Sokos & Zahradnik, 2008) and MATLAB. The seismicity is associated with the Goiás -Tocantins (GO-TO) Seismic Range (SR) that crosses the central part of Brazil in a NE-SW direction. The obtained focal mechanisms are in agreement with the results obtained by Barros et al. (2012) for 5.0 mb earthquake in this region.The Green functions were calculated using the 1-D velocity model determined by Soares et al (2006) for a model of point source located above and below the hypocenter. Ten hypocenters were tested, 5 above and 5 below to the given hypocenter. All seismograms were corrected for instrument response, band-pass-filtered, integrated to obtain displacement, and finally inverted for the DC (double couple) focal mechanism. The optimal solution produced the best correlation between the observed and synthetic seismograms, in one of the 10 points tested. However, a new search was attempted for each point source located on a plane passing through the hypocenter's optimal previous solution. This plane is divided into a rectangular grid, whose separation depends on the physical dimensions of the source investigated. The centroid (center of gravity of the fault displaced), corresponds to the solution that produces the best fit between the observed data and synthetics.We can conclude that the resulting consistency and the stability of the solutions indicate that this

In modern conditions, the financial system is a transfer mechanism of the business cycle and therefore affects the structure and dynamics of foreign direct investment, and especially the efficiency of their assimilation. The subject of the survey is the financial development and the FDI flows impact on economic growth. Methodology. The survey is based on the evaluation of the equation, which is the Barro regression specification. This model helps to find out the impact of the volume and depth of financial system on the dynamics of economic growth. GDP growth per capita is used as an indicator of economic growth. The paper proposes modeling results for the group countries (Hungary, Poland, Slovak and Czech Republic. Static data have been used for the period from 1992 to 2016. Results. FDI has an important role in reforming and developing the national economies of the countries in Visegrad Group. However, today, there is a problem with the stability of FDI inflows and with the efficiency of their development, which negatively affects the dynamics of economic growth. An important factor is the insufficient level of national financial system development of the Visegrad countries. All countries of the group have bank-oriented financial systems that are heavily dependent on foreign capital. At the same time, governments pay particular attention to the stability of banking sectors and set high standards for their sustainability. This holds back the financial development of the national economies of the Visegrad Group. At the same time, regression models for all countries confirm the importance of financial development in economic growth. The most important for V4 countries is to increase the size of the

Effect of 1RM, 80%RM, and 50%RM strength exercise in trained individuals on variations in plasma redox biomarkers. J Strength Cond Res 31(9): 2489-2497, 2017-For decades, scientists have examined the participation of oxygen/nitrogen species in anaerobic-like exercises, especially weightlifting and resistance exercises. The balance between the production of oxyradicals and antioxidant responses during anaerobic-like exercises is essential to assure adaptation to the physiological benefits of strength training and to prevent chronic harmful effects. The aim of this study is to examine the hypothesis that different weight loads (1 repetition maximum (RM), 80%RM, and 50%RM) lifted until exhaustion could impose distinct oxidative insults and elicit diverse antioxidant responses in plasma of young trained subjects. Glucose (+10%), lactate (+65%), urea (+30%), free iron (+65%), reduced/oxidized glutathione (+14 and +23%, respectively), and xanthine oxidase activity (2.2-fold) significantly increased after the 1RM test, whereas plasma antioxidant capacity dropped by 37%. When lower weight loads were applied (80%RM and 50%RM tests), heme-iron (+15 and +20%, respectively) became the prevalent pro-oxidant, although glutathione responses were only detected after 80%RM (+14%). Lactate concentration in plasma continuously increased, by 2.9-fold (80%RM) and 3.6-fold higher (50%RM test). We demonstrated that 1RM tests significantly diminish the antioxidant capacity of plasma because of iron overload, whereas 80%RM tests require higher involvement of glutathione molecules to counteract heme-iron oxidative insult. Mild redox imbalances promoted by heme-iron were found in plasma after 50%RM. Although we did not observe overall changes in muscle damage in young trained subjects, we cannot exclude the need for specific antioxidant supplementation depending on the

Therefore, the search for innovative strategies to prevent/delay these physiological and cognitive disorders is essential to guarantee the independence and life quality of an elderly population. The aim of this work is to verify the effect of a 12-week resistance exercise program on the general physical aptitude and cognitive capacities of elderly and sedentary women. Twenty-nine women (65.87±5.69 years were divided into two groups. The control group was composed of eight elderly women who met the same inclusion criteria of the study and the strength training group was composed of 29 elderly women who were subjected to a resistance exercise program defined by 12 upper and lower limb exercises combined in 3×10 repetitions with 1-minute interval between repetitions and two resting minutes between exercises (three times/week. Weight loads were fixed between 60% and 75% of the apparent 1 repetition maximum, which was estimated by the test of 10 maximum repetitions.

The anthelmintic activity in vitro was investigated using the inhibition of egg hatching assay (EHA, while cytotoxicity on Vero cells was evaluated using the MTT test. 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

    Full Text Available Nos verões de 1984 e 1985, foram feitos ensaios com armadilhas para pesquisa de Aedes aegypti. Em ambas as oportunidades destacou-se a armadilha feita cortando em três pedaços um pneu de automóvel. A armadilha autocida de Chan, modificada por Cheng et al. (1982, não foi capaz de competir com o pneu e os depósitos de barro, usados rotineiramente pela Superintendência de Campanhas de Saúde Pública (SUCAM. Verificou-se, também, que a colocação de plantas nas armadilhas aumenta muito a atratividade. Entretanto, essa prática não é interessante para uso rotineiro. Principalmente no caso do pneu é imprescindível o recolhimento da armadilha, por ocasião da inspeção e o seu enchimento com água. Este sistema dobrou a positividade dos pneus. Essa presença de ovos não eclodidos exige que as armadilhas sejam flambadas antes de serem expostas. O encontro de pupas sete dias depois da exposição, mostra que esse prazo não pode ser ultrapassado. O pneu, além de ter se revelado a armadilha mais eficiente, tem a vantagem de ser de custo nulo e não ser quebradiço.In the summer of 1984 and 1985 comparative trials for the surveillance of Aedes aegypti were performed. In both occasions the most effective trap was one made by cutting an automobile tire in three parts. The Chan´s autocide trap, modified by Cheng et al. (1982 was less effective than the tires as well as the baked clay containers routinely used by the "Superintendência de Campanhas de Saúde Pública (SUCAM." It was found also that plants on the traps increase to a great extent its attractiveness. This procedure however, is not functional for its routine use. The tires must always be taken to the laboratory and filled with water for the hatching of eggs. This practice has duplicated the positivity of the ovitrap. In view of the persistence of non hatched eggs the flaming of the traps must always be done before exposition. The finding of pupae 7 days after exposition shows

    Atmospheric dust deposition can be a significant source of phosphorus (P) in some tropical forests, so information on the origins and solubility of atmospheric P is needed to understand and predict patterns of forest productivity under future climate scenarios. We characterized atmospheric dust P across a seasonal cycle in a tropical lowland rain forest on Barro Colorado Nature Monument (BCNM), Republic of Panama. We traced P sources by combining remote sensing imagery with the first measurements of stable oxygen isotopes in soluble inorganic phosphate (δ(18)OP) in dust. In addition, we measured soluble inorganic and organic P concentrations in fine (1 μm) aerosol fractions and used this data to estimate the contribution of P inputs from dust deposition to the forest P budget. Aerosol dry mass was greater in the dry season (December to April, 5.6-15.7 μg m(-3)) than the wet season (May to November, 3.1-7.1 μg m(-3)). In contrast, soluble P concentrations in the aerosols were lower in the dry season (980-1880 μg P g(-1)) than the wet season (1170-3380 μg P g(-1)). The δ(18)OP of dry-season aerosols resembled that of nearby forest soils (∼19.5‰), suggesting a local origin. In the wet season, when the Trans-Atlantic Saharan dust belt moves north close to Panama, the δ(18)OP of aerosols was considerably lower (∼15.5‰), suggesting a significant contribution of long-distance dust P transport. Using satellite retrieved aerosol optical depth (AOD) and the P concentrations in aerosols we sampled in periods when Saharan dust was evident we estimate that the monthly P input from long distance dust transport during the period with highest Saharan dust deposition is 88 ± 31 g P ha(-1) month(-1), equivalent to between 10 and 29% of the P in monthly litter fall in nearby forests. These findings have important implications for our understanding of modern nutrient budgets and the productivity of tropical forests in the region under future climate scenarios.

General approaches on the behavior, ecology and physical abilities of this animal are available in the literature. However, information regarding different aspects of the anatomy of the nervous system giant anteater are sparsely found. Therefore, the morphological knowledge of the relationship between the spinal cord and vertebral column is of great importance to the scientific, as in the various species of animals, whether domestic or not, the relations of the caudal spinal differ. This difference comes out to meet the interests of wild animal medicine, especially as support for the practice of epidural anesthesia. Thus, the objective was to describe the topography of the conus M. tridactyla, providing anatomical data as a basis for the practice of epidural anesthesia.

Examination evidenced left eye proptosis, eyelid swelling, reduced visual acuity and afferent pupillary defect, without any inflammatory signs such as fever, hyperemia or tenderness. Computed tomography of the orbits showed a large superomedial subperiosteal hematoma in the left orbit. The patient was treated with canthotomy, cantholysis and surgical draining of the hematoma. Two days after drainage she persisted with a subperiosteal hematoma and low visual acuity. A wide exploration of the orbital roof through a lid crease approach disclosed a thickened superior orbital rim with multiple bone defects along the roof and with continuous bleeding. Hemostasis was accomplished with bone wax. Orbital compression was resolved and the patient recovered her previous normal visual acuity.Relatamos o caso de uma menina de 11 anos com doença falciforme, trazida à sala de emergência após ser atingida por um bloco de barro na região frontal esquerda. Apresentava ao exame proptose do olho esquerdo, edema palpebral, diminuição da acuidade visual e defeito pupilar aferente, sem quaisquer sinais inflamatórios como febre, hiperemia ou aumento de sensibilidade. A tomografia computadorizada de órbitas demonstrou um extenso hematoma subperiósteo superomedial na órbita esquerda. A paciente foi tratada com cantotomia, cantólise e drenagem cirúrgica do hematoma. Dois dias após a drenagem, ela permaneceu com um hematoma subperiósteo e a acuidade visual diminuída. Uma ampla exploração através de incisão no sulco palpebral superior revelou um rebordo orbitário superior espessado, e múltiplos defeitos ósseos ao longo do teto da órbita com sangramento persistente. Foi realizada hemostasia com cera óssea. A compressão orbitária foi resolvida, e a paciente recuperou a acuidade visual normal

    To characterize APC gene mutations and correlate them with patient phenotypes in individuals diagnosed with familial adenomatous polyposis (FAP) in northern Brazil. A total of 15 individuals diagnosed with FAP from 5 different families from the north of Brazil were analyzed in this study. In addition to patients with histopathological diagnosis of FAP, family members who had not developed the disease were also tested in order to identify mutations and for possible genetic counseling. All analyzed patients or their guardians signed a consent form approved by the Research Ethics Committee of the João de Barros Barreto University Hospital (Belem, Brazil). DNA extracted from the peripheral blood of a member of each of the affected families was subjected to direct sequencing. The proband of each family was sequenced to identify germline mutations using the Ion Torrent platform. To validate the detected mutations, Sanger sequencing was also performed. The samples from all patients were also tested for the identification of mutations by real-time quantitative polymerase chain reaction using the amplification refractory mutation system. Through interviews with relatives and a search of medical records, it was possible to construct genograms for three of the five families included in the study. All 15 patients from the five families with FAP exhibited mutations in the APC gene, and all mutations were detected in exon 15 of the APC gene. In addition to the patients with a histological diagnosis of FAP, family members without disease symptoms showed the mutation in the APC gene. In the present study, we detected two of the three most frequent germline mutations in the literature: the mutation at codon 1309 and the mutation at codon 1061. The presence of c.3956delC mutation was found in all families from this study, and suggests that this mutation was introduced in the population of the State of Pará through ancestor immigration (i.e., a de novo mutation that arose in one

We compared neuropsychological performance using language and Mini-Mental State Examination (MMSE test scores before and after 24 and 48 stimulation sessions. The two groups were matched by age and years of schooling. Small groups of ten or fewer volunteers underwent the stimulation program, twice a week, over 6 months (48 sessions in total. Sessions were based on language and memory exercises, as well as visual, olfactory, auditory, and ludic stimulation, including music, singing, and dance. Both groups were assessed at the beginning (before stimulation, in the middle (after 24 sessions, and at the end (after 48 sessions of the stimulation program. Although the NI group showed higher performance in all tasks in all time windows compared with I subjects, both groups improved their performance after stimulation. In addition, the improvement was significantly higher in the I group than the NI group. Language tests seem to be more efficient than the MMSE to detect early changes in cognitive status. The results suggest the impoverished environment of long-term-care institutions may contribute to lower cognitive scores before stimulation and the higher improvement rate of this group after stimulation.

Em cada 10 dias, durante todo o ciclo vegetativo, eram colhidas plantas e analisados os teores de N, P, K, Ca, Mg e S. Tôdas as plantas receberam os mesmos cuidados em tratos culturais, fitossanitários e água. Propiciaram-se, ainda, iguais condições de fertilidade, dando-se a todos os vasos adubação completa, inclusive com os micronutrientes necessários ao bom desenvolvimento e produção da batata. Os resultados obtidos mostram que a batata absorve em grande quantidade o nitrogênio e o potássio, sendo o último em maior proporção. Dos outros elementos estudados, o fósforo, o cálcio, o magnésio e enxôfre, são absorvidos em pequenas quantidades, não ultrapassando nenhum dêles 16 kg/ha. Os dados mostram ainda que as quantidades totais necessárias de nitrogênio, potássio, magnésio e enxôfre são absorvidas pela cultura, até completar 50 dias após a germinação, enquanto o fósforo e o cálcio são requeridos desde o inicio até o final do ciclo vegetativo da planta.Nutritional studies were carried out with potted potato plants, aiming at determining the absorption rate and uptake of essential nutrients in relation to age of the crop. The experimental plants were grown in pots containing 10 kg of soil. Cultural practices, water, and fertility conditions (including addition of minor elements were uniform for all pots. Samples composed of an adequate number of plants (according to age were harvested at ten-day intervals during the entire vegetative cycle of the crop and analysed for N, P, K, Ca, Mg, and S. The results obtained indicated that the potato plant absorbs a large amount of nitrogen, followed by potassium. Phosphorus, calcium, magnesium, and sulfur are absorbed in small quantities, not more than 16 kg

    Full Text Available RESUMEN Objetivo Realizar un diagnóstico de salud ambiental infantil y un análisis de percepción de riesgos en comunidades indígenas de la Región Huasteca Sur de San Luis Potosí, México, para diseñar una estrategia de intervención acorde a sus necesidades. Métodos La investigación siguió un enfoque mixto realizado en dos fases de estudio. Se desarrolló en tres comunidades indígenas del municipio de Tancanhuitz, desde enero de 2005 hasta junio de 2006. En la población adulta, se analizó la percepción de riesgos mediante grupos focales, entrevistas a profundidad y cédulas de entrevistas. En la población infantil, para el análisis de percepción se utilizó la técnica de dibujo. Se realizó una evaluación de riesgos a la salud a través de un monitoreo biológico y un monitoreo ambiental de agua y suelo. Resultados Las tres comunidades enfrentan problemas críticos que hacen evidente su vulnerabilidad. Al realizar la triangulación e integración de resultados, se halló que las principales problemáticas se relacionan con la exposición a microorganismos patógenos en el agua y el suelo, la exposición a humo de leña en interiores, la exposición al humo por quema de basura, el uso de insecticidas, la exposición a plomo por uso de barro vidriado y el alcoholismo. Conclusiones Para que la estrategia de intervención sea acorde a la población que será intervenida, es fundamental incorporar el análisis de percepción de riesgos y fomentar la participación de sus integrantes. La estrategia de intervención que se propone para atender las problemáticas detectadas se basa en los principios de comunicación de riesgo, la participación comunitaria y la vinculación interinstitucional.

    Aim Some species reach extraordinary densities on islands. Island assemblages have fewer species, however, and it is possible that island species differ from their mainland counterparts in average mass. Island assemblages could be partitioned differently (fewer species or smaller individuals) from mainland sites without differing in aggregate biomass (density compensation). Our objective was to determine the generality of excess density compensation in island herpetofaunal assemblages.Location Our bounded removal plot data were obtained from Pacific Island sites (Guam, Saipan and Rota), the West Indies (British Virgin Islands), and the Indian Ocean (Ile aux Aigrettes off Mauritius). The literature values were taken from several locales. Other island locations included Barro Colorado Island, Bonaire, Borneo, Philippine Islands, Seychelle Islands, Barrow Island (Australia), North Brother Island (New Zealand), Dominica and Puerto Rico. Mainland sites included Costa Rica, Ivory Coast, Cameroon, Australia, Thailand, Peru, Brazil, Panama and the USA.Method We added our thirty-nine bounded total removal plots from sixteen island habitats to fifteen literature records to obtain seventy-five venues with estimable density and biomass of arboreal or terrestrial herpetofaunal assemblages. These biomass estimates were evaluated geographically and in relation to sampling method, insularity, latitude, disturbance regime, seasonality, community richness, vegetative structure and climate. Direct data on trophic interactions (food availability, parasitism and predation pressure) were generally unavailable. Sampling problems were frequent for arboreal, cryptic and evasive species.Results and main conclusions We found strong evidence that herpetofaunal assemblages on small islands (mostly lizards) exhibit a much greater aggregate density of biomass (kg ha−1) than those of larger islands or mainland assemblages (small islands show excess density compensation). High aggregate biomass

    Full Text Available Este artículo se desenvuelve alrededor de cuatro líneas argumentales en relación al dinero. Por un lado, parte de una breve introducción que toma en cuenta tanto su origen, como hijo legítimo del comercio, como la influencia que ha tenido en la expansión de antiguos imperios. En la segunda sección se presentan aspectos históricos y contextuales que han llevado a materializarlo de diferentes formas en los distintos núcleos humanos que abarcan desde pieles hasta conchas de caurí, pasando por cuentas de barro o barras de sal. La dimensión simbólica del dinero se ejemplifica en este apartado cuando se lo relaciona a la imagen del poder, su función como vehículo de información y propaganda o el significado místico-religioso que adquiere en diferentes culturas. En la tercera parte se hace una mayor profundización de la entidad simbólica del dinero desde la perspectiva del Interaccionismo Simbólico. La creencia que un símbolo es un hecho social compartido y que un fenómeno tiene significado en relación directa a su función práctica permite considerar este marco teórico como un constructo válido para estudiar el dinero. Por último, se plantea la existencia de dineros especiales. Avanzando más allá del cariz instrumental del dinero aportado por la economía, la visión de la antropología y la sociología nos demuestran que existen en el dinero aspectos culturales y sociales fuera de la esfera del mercado y que éstos pueden inclusive ser causas de «mutaciones», como es el caso del dinero virtual.

    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).

    Full Text Available CONTEXT: Mid-arm circumference of the newborn is strongly associated with birth weight and is a very good indicator of low and insufficient birth weight. However, there are few Brazilian studies on the relationship between mid-arm and head circumferences and, thus, this does not form part of the routine evaluation for newborns. OBJECTIVES: To establish the mid-arm circumference and mid-arm/head circumference ratio in a population of term newborns. TYPE OF STUDY: Cross-sectional study carried out between June 1997 and August 1999. SETTING: Hospital Maternidade Leonor Mendes de Barros, São Paulo. PARTICIPANTS: Term newborns (66 males and 65 females of appropriate growth for gestational age, whose mothers were healthy, were included in the study. MAIN MEASUREMENTS: Arm circumference, arm circumference/head circumference ratio, birth weight and gestational age were measured within 48 hours of birth. Data were considered significant when p < 0.01. RESULTS: The mean values for the mid-arm circumference were 10.76 cm (standard deviation, SD = 0.68 for females and 10.76 (SD = 0.81 for males. The mean value for the mid-arm/head circumference ratio was 0.31 (SD = 0.02 for both sexes. Mid-arm circumference values were significantly related to birth weight and gestational age, whereas mid-arm/head circumference ratio was related only to birth weight. CONCLUSIONS: Mid-arm circumference and mid-arm/head circumference ratio values were established for the studied population. It was possible to obtain curves for both mid-arm circumference and mid-arm/head circumference ratio in relation to birth weight. However, for mid-arm circumference, it was only possible to obtain curves in relation to gestational age. The use of the regression curves did not seem powerful enough to predict the mid-arm circumference and mid-arm/head circumference ratio in this population of term newborns. There were no gender differences for either of the measurements studied.

    Accurate estimates of tree mortality are essential for the development of mechanistic forest dynamics models, and for estimating carbon storage and cycling. However, identifying agents of tree mortality is difficult and imprecise. Although lightning kills thousands of trees each year and is an important agent of mortality in some forests, the frequency and distribution of lightning-caused tree death remain unknown for most forests. Moreover, because all evidence regarding the effects of lightning on trees is necessarily anecdotal and post hoc, rigorous tests of hypotheses regarding the ecological effects of lightning are impossible. We developed a combined electronic sensor/camera-based system for the location and characterization of lightning strikes to the forest canopy in near real time and tested the system in the forest of Barro Colorado Island, Panama. Cameras mounted on towers provided continuous video recordings of the forest canopy that were analyzed to determine the locations of lightning strikes. We used a preliminary version of this system to record and locate 18 lightning strikes to the forest over a 3-year period. Data from field surveys of known lightning strike locations (obtained from the camera system) enabled us to develop a protocol for reliable, ground-based identification of suspected lightning damage to tropical trees. In all cases, lightning damage was relatively inconspicuous; it would have been overlooked by ground-based observers having no knowledge of the event. We identified three types of evidence that can be used to consistently identify lightning strike damage in tropical forests: (1) localized and directionally biased branch mortality associated with flashover among tree and sapling crowns, (2) mortality of lianas or saplings near lianas, and (3) scorched or wilting epiphytic and hemiepiphytic plants. The longitudinal trunk scars that are typical of lightning-damaged temperate trees were never observed in this study. Given the

    Full Text Available BACKGROUND: Local plant-soil associations are commonly studied at the species-level, while associations at the level of nodes within a phylogeny have been less well explored. Understanding associations within a phylogenetic context, however, can improve our ability to make predictions across systems and can advance our understanding of the role of evolutionary history in structuring communities. METHODOLOGY/PRINCIPAL FINDINGS: Here we quantified evolutionary signal in plant-soil associations using a DNA sequence-based community phylogeny and several soil variables (e.g., extractable phosphorus, aluminum and manganese, pH, and slope as a proxy for soil water. We used published plant distributional data from the 50-ha plot on Barro Colorado Island (BCI, Republic of Panamá. Our results suggest some groups of closely related species do share similar soil associations. Most notably, the node shared by Myrtaceae and Vochysiaceae was associated with high levels of aluminum, a potentially toxic element. The node shared by Apocynaceae was associated with high extractable phosphorus, a nutrient that could be limiting on a taxon specific level. The node shared by the large group of Laurales and Magnoliales was associated with both low extractable phosphorus and with steeper slope. Despite significant node-specific associations, this study detected little to no phylogeny-wide signal. We consider the majority of the 'traits' (i.e., soil variables evaluated to fall within the category of ecological traits. We suggest that, given this category of traits, phylogeny-wide signal might not be expected while node-specific signals can still indicate phylogenetic structure with respect to the variable of interest. CONCLUSIONS: Within the BCI forest dynamics plot, distributions of some plant taxa are associated with local-scale differences in soil variables when evaluated at individual nodes within the phylogenetic tree, but they are not detectable by phylogeny

These patients were older, had longer disease duration, longer follow-up in each center, reported lower frequency of self-reported hypoglycemia, and were more frequently Caucasians and at glycemic goal. Multivariate analysis showed that knowledge on what HbA1c means was related to more years of school attendance, self-reported ethnicity (Caucasians, severe hypoglycemia, economic status, follow-up time in each center, and participation on diabetes educational programs. Good glycemic control was related to older age, more years of school attendance, higher frequency of daily self-monitoring of blood glucose, higher adherence to diet, and knowledge on what HbA1c means.Conclusion: Patients with a knowledge on what HbA1c means had a better chance of reaching an adequate glycemic control that was not found in the majority of our patients. Diabetes care teams should rethink the approaches to patients and change them to more proactive schedules, reinforcing education, patients’ skills, and empowerment to have positive attitudes toward reaching and maintaining a better glycemic control.

For statistical analysis we used the nonparametric Mann–Whitney U test, with a significance level of 5%.Results: In comparisons of variables between the groups, the experimental group outperformed by at least 75% of the control group values. In terms of global trends, the experimental group shows higher values of body oscillations in all experimental conditions and variables evaluated. Children with hearing loss had poorer balance performance compared to the group of hearing. The inferential analysis revealed a statistically significant difference in the balance between deaf and hearing children in the OBEC experimental condition in relation to the COPml parameter (P = 0.04. There were no statistically significant differences in comparisons between the sexes when the groups were analyzed separately. The prevalence of unknown etiology

This study aimed to analyze the prophylactic effects of treatment with a soybean oil-rich diet (rich in n-6 or fish oil (rich in n-3 in an allergic airway inflammation model on lung inflammation score, leukocyte migration, T-helper cell (Th-2 (interleukin [IL]-4, IL-5 and Th1 (interferon [IFN]-γ, tumor necrosis factor-α cytokines, lipoxin A4, nitric oxide, bradykinin, and corticosterone levels in bronchoalveolar lavage (BAL or lungs. Methods: Male Wistar rats fed with soybean oil- or fish oil-rich diet or standard rat chow were sensitized twice with ovalbumin–alumen and challenged twice with ovalbumin aerosol. The BAL and lungs were examined 24 hours later. Results: Both diets, rich in n-6 or n-3 FAs, impaired the allergic lung inflammation and reduced leukocyte migration, eosinophil and neutrophil percentages, and IL-4/IL-5/bradykinin levels in BAL and/or lungs, as well as increased the nitric oxide levels in BAL. The soybean oil-rich diet additionally increased the levels of lipoxin A4 and corticosterone in the lungs. Conclusion: Data presented demonstrated that the n-6 FA-rich diet had protective effect upon allergic airway inflammation and was as anti-inflammatory as the n-3 FA-rich diet, although through different mechanisms, suggesting that both diets could be considered as complementary therapy or a prophylactic alternative for allergic airway inflammation.

  18. A Drone-based Tropical Forest Experiment to Estimate Vegetation Properties

    In mid-latitudes, remote sensing technology is intensively used to monitor vegetation properties. However, in the tropics, high cloud-cover and saturation effects of vegetation indices (VI) hamper the reliability of vegetation parameters derived from satellite data. A drone experiment over the Barro Colorado Island (BCI), Panama, with high temporal repetition rates was conducted in spring 2017 to investigate the robustness and stability of remotely sensed vegetation parameters in tropical environments. For this purpose, three 10-day flight windows in February, March and April were selected and drone flights were repeated on daily intervals when weather conditions and equipment allowed it. In total, 18 days were recorded with two different optical cameras on sensefly's eBee drone: one red, green, blue (RGB) camera and one camera with near infra-red (NIR), green and blue channels. When possible, the data were acquired at the same time of day. Pix4D and Agisoft software were used to calculate the Normalized Difference VI (NDVI) and forest structure. In addition, leave samples were collected ones per month from 16 different plant species and the relative water content was measured as ground reference. Further data sources for the analysis are phenocam images (RGB & NIR) on BCI and satellite images of MODIS (NDVI; Enhanced VI EVI) and Sentinel-1 (radar backscatter). The attached figure illustrates the main data collected on BCI. Initial results suggest that the coefficient of determination (R2) is relatively high between ground samples and drone data, Sentinel-1 backscatter and MODIS EVI with R2 values ranging from 0.4 to 0.6; on the contrary, R2 values between ground measurements and MODIS NDVI or phenocam images are below 0.2. As the experiment took place mainly during dry season on BCI, cloud-cover rates are less dominate than during wet season. Under these conditions, MODIS EVI, which is less vulnerable to saturation effects, seems to be more reliable than MODIS

  19. Coupled nutrient cycling determines tropical forest trajectory under elevated CO2.

    Tropical forests have a disproportionate capacity to affect Earth's climate relative to their areal extent. Despite covering just 12 % of land surface, tropical forests account for 35 % of global net primary productivity and are among the most significant of terrestrial carbon stores. As atmospheric CO2 concentrations increase over the next century, the capacity of tropical forests to assimilate and sequester anthropogenic CO2 depends on limitation by multiple factors, including the availability of soil nutrients. Phosphorus availability has been considered to be the primary factor limiting metabolic processes within tropical forests. However, recent evidence points towards strong spatial and temporal co-limitation of tropical forests by both nitrogen and phosphorus. Here, we use the Accelerated Climate Modeling for Energy (ACME) Land Model (ALMv1-ECA-CNP) to examine how nutrient cycles interact and affect the trajectory of the tropical forest carbon sink under, (i) external nutrient input, (ii) climate (iii) elevated CO2, and (iv) a combination of 1-3. ALMv1 includes recent theoretical advances in representing belowground competition between roots, microbes and minerals for N and P uptake, explicit interactions between the nitrogen and phosphorus cycles (e.g., phosphatase production and nitrogen fixation), the dynamic internal allocation of plant N and P resources, and the integration of global datasets of plant physiological traits. We report nutrient fertilization (N, P, N+P) predictions for four sites in the tropics (El Verde, Puerto Rico, Barro Colorado Island, Panama, Manaus, Brazil and the Osa Peninsula, Coast Rica) to short-term nutrient fertilization (N, P, N+P), and benchmarking of the model against a meta-analysis of forest fertilization experiments. Subsequent simulations focus on the interaction of the carbon, nitrogen, and phosphorus cycles across the tropics with a focus on the implications of coupled nutrient cycling and the fate of the tropical

  20. Determining Age and Origin of Spodumene-Bearing Pegmatites in Southeastern Ireland

    2017-12-01

    Exploration prospecting around Caldonian Leinster Granite has revealed pegmatite intrusions containing spodumene, a lithium ore, on the eastern margin of the Tullow Lowlands Pluton. Drill cores of these pegmatites have been extracted and studied due to increasing economic interest. Ages between 430 and 400 Ma for spodumene pegmatites have been previously determined using the in situ Rb-Sr isochron method [1]. Here we use the Sm-Nd isochron method to see if the less-mobile nature of REEs during contact metamorphism and deformation impacts ages. Suitable samples containing garnet and feldspar from spodumene and barren pegmatites were studied using regular microscopy and SEM; minerals were then isolated manually. After mineral dissolution and elemental separation via ion exchange columns, a Neptune MS measured Sm and Nd isotope ratios. Blank corrections were applied. Both types of pegmatites were used to calculate an isochron using Isoplot 3.7 [2] which yielded an initial 143Nd/144Nd ratio of 0.51190±0.00009, and an age of 414±52 Ma. Ages and ɛNd, relating to the initial Nd ratio, were compared with previous whole rock data of Leinster Granite [3] and Rb-Sr multimineral data [1]. Comparable ages from both methods likely represent crystallization age. At the minimum possible age considering uncertainty, the origins of pegmatites and granitic rocks are indistinguishable, but at the maximum age, pegmatites show lower ɛNd values suggesting heterogeneous sources. All representative data points held negative ɛNd values signifying crustal assimilation. The Sm-Nd method was found suitable for age/ source investigation; however, Leinster pegmatite garnet is particularly depleted in Nd (<1 ppm), yielding poor precision, and further study using less depleted samples should be conducted for better age determination.

Various tests can be used for SCC. For convenience and accuracy there is the electronic counting by flow cytometry. Microscopic slides count is the standard method for the determination of SCC in raw milk with the classic method described by Prescot and Breed (1910. This study aimed to evaluate the differential cell count in milk of cows with subclinical mastitis, by optical microscopy, in slides stained by May Grunwald-Giemsa and Gram. In both staining the cells showed morphological changes. However, the unidentifiable cell percentage did not exceed 10% enhancing the applicability of the differential cell counts, as used in leucocytes in hematologic smears. There were small variations in the counts with the two colorations. There was a predominance of neutrophils (˃60%, followed by lymphocytes (˃25% consistent with the characterization of the samples as coming from rooms with subclinical mastitis. May Grunwald- -Giemsa stain showed similar results to Gram. The main differences between the colorations are based on the amplitude and intensity of staining, the Gram stain which stood out. In Gram

    Full Text Available Fortaleza é uma metrópole que apresenta distribuição de renda perversa e problemas de ocupação do solo. A Baixada do Aratu é uma Área de Preservação Permanente localizada no curso do rio Cocó, cujo manto vegetal é constituído por manguezal. A especulação imobiliária e a falta de uma política de habitação empurraram para a Baixada aproximadamente 200 famílias que residem na área em condições sub-humanas. A pesquisa, de natureza qualitativa, teve como objetivo conhecer a realidade social e epidemiológica dos moradores da Baixada do Aratu, tendo sido realizada em janeiro e fevereiro de 2001, através de questionário e visita domiciliar, com amostra de 70 famílias. Encontrou-se que 90% das famílias obtêm água tratada através de ligações clandestinas e 10% a retiram de poços sem qualquer tratamento. Os barracos são construídos com madeira e barro do manguezal ou com restos de material de construção. As doenças mais comuns são as respiratórias, com 54%, seguidas de hipertensão arterial (14%, alcoolismo (11%, doenças diarréicas (8,5%, doenças dermatológicas (6% e 6,5% por outras causas. Verificou-se a associação entre precárias condições de vida, problemas de saúde reincidentes e crescentes agressão à natureza. Conclui-se que mais estudos devem ser desenvolvidos com o objetivo entender as relações que ocorrem entre tais fatores para o serviço de saúde vinculado à Universidade de Fortaleza, possa ser capaz de construir uma proposta de intervenção adequada à realidade dos moradores.

Here, orange (Citrus sinensis waste was utilized as a source of an extract for AgNP synthesis (the protein corona composition of which was elucidated, and also as a starting material for hesperidin and nanocellulose extraction, which were used for bio-based AgNP synthesis. A comparison of the results using the two methods of synthesis is presented. Methods: AgNPs were synthesized using orange (C. sinensis peel extract (­Or-AgNPs in a biological route, and using hesperidin (Hsd-AgNPs and nanocellulose (extracted from oranges in a green chemical route. Characterization of nanoparticles was carried out using zeta potential and hydrodynamic size measurements, transmission electron microscopy, and X-ray diffraction. Elucidation of proteins from protein corona was performed via ultra performance liquid chromatography-tandem mass spectrometer experiments. Antimicrobial activity was assessed via minimum inhibitory concentration assays against Xanthomonas axonopodis pv. citri (Xac, the bacterium that causes citric canker in oranges. Results: Or-AgNPs were not completely uniform in morphology, having a size of 48.1±20.5 nm and a zeta potential of −19.0±0.4 mV. Stabilization was performed mainly by three proteins, which were identified by tandem mass spectrometry (MS/MS experiments. Hsd-AgNPs were smaller (25.4±12.5 nm and had uniform morphology. Nanocellulose provided a strong steric and electrostatic (−28.2±1.0 mV stabilization to the nanoparticles

Dando un primer paso al respecto, es que hemos experimentado, en probetas RILEM, el comportamiento de algunas de las respuestas del mortero de barro seco, al variar factores como son la arcilla, el limo, la arena y la cantidad de agua de amasado. Los resultados de este estudio, pueden resumirse en las siguientes cuatro recomendaciones básicas: 1. Emplear suelos con razón limo-arcilla cercano a uno y la sumatoria entre 35 y 45% del total. 2. El contenido de arena del suelo debe encontrarse entre un 55% y un 65%. 3. La cantidad óptima para el agua de amasado depende de las propiedades mismas del suelo y de la tecnología empleada. En nuestro caso, dicho óptimo se encuentra en el límite líquido, más un tercio del índice de plasticidad de los suelos. Cabe hacer notar el alto nivel de significación de este factor en todas las variables estudiadas y sería de gran ventaja poder controlar su contenido, sin embargo, a niveles artesanales; esto no ha sido posible. 4.

Nas provas usamos recipientes de barro, recobertos de fina camada de prata na parede interna, ou aquêles em que a prata, sob a forma de pó se misturava ao próprio barro. Esses recipientes são denominados, no comércio, moringas esterilizantes. Colocou-se, no seu interior, a emulsão a 10% do tecido cerebral contendo o vírus da coriomeningite linfocitária ou da poliomielite, verificando-se o seu poder patogênico para camundongos, em intervalos regulares, pela injeção intracerebral de 0,03 ml do material. Os resultados, que podem ser vistos nos Quadros 1 e 2, indicam que aquêles virus resistem à ação oligodinâmica da prata. No caso do vírus da vacina, a diluição foi colocada, da mesma maneira, nos referidos recipientes. O vírus apresentou, também, completa resistência, conforme se vê nas figuras de 1, 2 e 3. Experiências testemunhas feitas com Micrococcus pyogenes e Escherichia coli, cujas suspensões foram igualmente colocadas nas moringas esterilizantes, revelaram que as bactérias não sobreviviam além de 20 horas. Frizamos, na publicação sôbre vírus da gripe, que o referido fenômeno é importante porque sabemos que o efieto oligodinâmico se observa sôbre microorganismos como bactérias, protozoários e outros seres vivos, alterando as suas propriedades ou matando-os sendo, portanto, interessante sob o ponto de vista biológico.

The work was articulated based on the participation of ASCES teachers in the Research Group of UFPE-CNPq, and on the perception of how the integration of institutional activities could improve results and include a larger number of teachers, students, and beneficiaries - prisoners and educators of the penitentiary system. The actions involving broad participation of civil society were carried out fortnightly at the prison unit; the works are presented in the form of training meetings with teachers, lectures, and discussions with inmates, as well as in activities mediated by playful elements such as images, photographs, films, documentaries, music, and poetry. Students from the two institutions are integrated without competition; teachers receive continuing education; and recreational activities with the inmates break their prison routine and encourage them to remain in the classroom, reducing evasion. The activity is used as internship workload for the ASCES students and as supplementary activities for students of Pedagogy. These activities also allow the two institutions to contribute for improving the quality of education in prison; motivate the interaction of students from different institutions, including students form institutions that do not belong to the projects, attracting the participation of many volunteers and alumni from the ASCES and the Faculty of Philosophy, Sciences and Languages of Caruaru

    (Marinho et al., 2013. Erythromycin and tetracycline are widely used in human therapy, and this may have contributed to the increasing resistance to these antibiotics (Hummel et al., 2007, Barros et al., 2011. It also highlights the lack of antibiotic efficiency in medicine, doing with resistance dissemination. Also, several genes associated with antimicrobial resistance were already found in antimicrobial-resistant enterococci from echinoderms: tet(M/tet(L, erm(A/erm(B, vat(D/vat(E, aac(6’-aph(2'' and aph(3'-IIIa genes were detected in tetracycline, erythromycin, quinupristin-dalfopristin, gentamicin and kanamycin-resistant isolates, respectively (Marinho et al., 2013. Despite of the small number of Escherichia coli isolates from echinoderms samples, they displayed an antibiotic-resistant phenotype to: tetracycline, streptomycin, tobramycin and amoxicillin + clavulanic acid. E. coli isolates from echinoderms tetracycline-resistant had tet(A and tet(B genes present in their genome. Besides, the aadA gene was detected in all E. coli streptomycin-resistant strains isolated from echinoderms (Marinho et al., 2013. According to some results, enterococci and E. coli displaying phenotype and resistance genes to some antibiotics that were already documented in marine animals, humans, wastewaters and numerous wildlife animals (Marinho et al., 2013, Barros et al., 2011, Sousa et al., 2011, Foti et al., 2009. Echinoderms are coastal animals and, consequently, it is possible that sewage discharges at the ocean may represent the main source of antibiotic-resistant bacteria deriving from several habitats. Indirect effects in micro-systems from the antibiotic disturbance are largely unknown; however, it is expected that such disorder might have significant long-term effects on the rate and stability of the ecosystem. Nevertheless, the consumption of exotic food is an example of a potential pathway for human contact with marine echinoderms microbiota, which may contain antibiotic

Neste contexto, o objetivo deste trabalho foi identificar diferenças no ambiente interno de dois galpões de poedeiras, utilizando monitoramento e posterior comparação estatística das variáveis do ambiente. A análise dos dados não evidenciou maior conforto térmico no galpão recoberto com telhas de barro, em razão da ausência de lanternim que dificultou a renovação do ar por "efeito chaminé".

    Full Text Available Depuis 1953, de nombreux chercheurs se sont intéressés à la datation par thermoluminescence de minéraux anciennement brûlés ou cuits. Dans ce travail, après avoir rappelé quelques principes physiques de la thermoluminescence, on présente cette méthode de datation en mettant l'accent sur le mécanisme thermoluminescent dans une poterie. Ainsi la dose d'irradiation reçue par le matériau étant proportionnelle au temps écoulé depuis le 'zéro archéologique', il est possible de déterminer 'la dose archéologique' et d'en déduire l'âge de l'échantillon après avoir calculé la dose d'irradiation annuelle. La réalisation pratique d'un tel ensemble de mesure est cependant très ardue. Dans un prochain article, E. A. Decamps et A. Roman montreront des résultats relatifs à la thermoluminescence d'échantillons de quartz naturels, purs et dopés et la mise au point d'une nouvelle méthode de datation. Desde 1953, muchos investigadores se han interesado en la datación por termoluminiscencia de minerales antiguamente quemados o cocidos. Dentro de este trabajo, luego de haber recordado algunos principios físicos de la termoluminiscencia, se presenta este método de datación poniendo mayor atención en el mecanismo termoluminescente en una vasija de metal o de barro. Siendo proporcional la dosis de irradiación recibida al tiempo transcurrido desde el 'cero arqueológico', es posible determinar 'la dosis arqueológica', y deducir la edad de la muestra luego de haber calculado la dosis de irradiación anual.

    Following the catastrophic loss of life from the December 26, 2004, Sumatra-Andaman Islands earthquake and tsunami, the U.S. Government appropriated funds to improve monitoring along a major portion of vulnerable coastal regions in the Caribbean Sea, the Gulf of Mexico, and the Atlantic Ocean. Partners in this project include the United States Geological Survey (USGS), the National Oceanic and Atmospheric Administration (NOAA), the Puerto Rico Seismic Network (PRSN), the Seismic Research Unit of the University of the West Indies, and other collaborating institutions in the Caribbean region. As part of this effort, the USGS is coordinating with Caribbean host nations to design and deploy nine new broadband and strong-motion seismic stations. The instrumentation consists of an STS-2 seismometer, an Episensor accelerometer, and a Q330 high resolution digitizer. Six stations are currently transmitting data to the USGS National Earthquake Information Center, where the data are redistributed to the NOAA's Tsunami Warning Centers, regional monitoring partners, and the IRIS Data Management Center. Operating stations include: Isla Barro Colorado, Panama; Gun Hill Barbados; Grenville, Grenada; Guantanamo Bay, Cuba; Sabaneta Dam, Dominican Republic; and Tegucigalpa, Honduras. Three additional stations in Barbuda, Grand Turks, and Jamaica will be completed during the fall of 2007. These nine stations are affiliates of the Global Seismographic Network (GSN) and complement existing GSN stations as well as regional stations. The new seismic stations improve azimuthal coverage, increase network density, and provide on-scale recording throughout the region. Complementary to this network, NOAA has placed Deep-ocean Assessment and Reporting of Tsunami (DART) stations at sites in regions with a history of generating destructive tsunamis. Recently, NOAA completed deployment of 7 DART stations off the coasts of Montauk Pt, NY; Charleston, SC; Miami, FL; San Juan, Puerto Rico; New

    Full Text Available We analyse how physical and chemical deep-cave sediment features preserve the morphological and geochemical characteristics of paleontological materials. Detrital sediment chemistry and clast size are fundamental because they provide a soft, impervious and plastic environment in which fossil remains are transported with minimal erosion. Sediment mineralogy provides a carbonate- and phosphate-buffered environment in which molecules of biological origin hydrolyze slower than in open-air environments or even at cave entrance sites. Because permafrost did not develop in the Iberian Peninsula (at least at the altitudes of inhabited caves, sediment desiccation never took place. In addition, sediment -pores were not aerated, which protected fossil remains from air (oxygen-linked weathering. The annual-temperature variation inside sediment was negligible, which contributed to amino acid racemization dating. Collagen amino acid and amino acid racemization analysis of cave bear and man samples from cave sediments dated from different Oxygen Isotope Stages (4": Sidrón, Amutxate, Troskaeta, El Toll, Coro Tracito, Ekain, Lezetxiki, La Pasada, Eirós; 5": Reguerillo and Arrikrutz; 6"-7": Sima de los Huesos demonstrate that important amounts of almost intact collagen still remain in teeth dentine.

    Full Text Available A conservação das áreas de preservação permanente sofre com o desrespeito principalmente pelo seu desconhecimento, a aplicação da lei não é fácil devido à imprecisão de seus limites espaciais. O presente artigo discute a interpretação e a aplicação da legislação, na determinação dos limites das Áreas de Preservação Permanente relacionadas ao relevo. O objetivo consistiu em indicar todas as categorias previstas, em duas microbacias hidrográficas, a do Ribeirão João Leite e a do Ribeirão Extrema, mananciais hídricos para abastecimento de dois centros urbanos, respectivamente, Goiânia e Barro Alto, procurando o resultado da efetiva área de preservação permanente e dos conflitos decorrentes de seus usos. Foram mapeadas oito categorias de APP, as quais se repetiram nas duas bacias: faixas marginais de 30m e 50m nos cursos d’água; faixas marginais de lagoas/reservatórios; raio marginal de 50m nas nascentes; recuo de 100m nas bordas de tabuleiros; topos de morro; linhas de cumeada e as escarpas. Também foram elaborados os mapas de uso e ocupação das duas bacias, para cruzamento com os de APP. Destes mapas, constatou-se que na Bacia do Ribeirão João Leite, apenas 22,23% encontram-se recobertos por remanescentesde vegetação, principalmente Florestas Estacionais Deciduais e Semideciduais: verifica-se o predomínio das pastagens, que alcançam 65% da área. Já no Ribeirão Extrema, 43,62% estão cobertos por remanescentes, principalmente Cerrado Típico e Cerradão; também ocorre o predomínio das pastagens, abrangendo 48,34%. Em relação às APP, no Ribeirão João Leite, o total correspondeu a 18,25% de sua área, já no Ribeirão Extrema, 26,82%, sendo a classe dos topos de morro a predominante em ambas. Percebe-se uma discrepância entre os padrões de uso e ocupação: no Ribeirão João Leite 62,07% de todas as APP estão sob uso; no Ribeirão Extrema esse cenário é bem diferente, com 78,2% de preserva

  1. Changes in Arbuscular Mycorrhizal Fungal Abundance and Community Structure in Response to the Long-Term Manipulation of Inorganic Nutrients in a Lowland Tropical Forest

    The arbuscular mycorrhizal (AM) symbiosis is considered primarily mutualistic. In exchange for up to 30% of plants' total photosynthate, AM provide improved access to mineral nutrients. While there is evidence that AM fungi provide nitrogen, potassium and other nutrients to their host plants, most research has focused on their effect on plant phosphorus uptake. Pot experiments have shown, and field experiments have provided further support, that nutrient availability (primarily P, but also N) is inversely correlated with mycorrhizal colonization, indicating plant control over carbon losses to AM fungi. Yet pot experiments have also shown that some fungal species are more mutualistic than others and that AM colonization may cause decreased plant growth, suggesting that plant control is not absolute. AMF communities are diverse, and it is poorly understood how factors such as adaptation to local soil environment, fungal-plant compatibility, and plant nutrient status combine to shape AMF community structure. We conducted a study to examine the relative effects of N, P, and K addition on the AMF community in a plant species rich tropical forest, given the long-held belief that AMF are primarily involved in plant P uptake, particularly on weathered tropical soils. Our study site is the Barro Colorado Nature Monument in Panama. It is a 13 year-old factorial N, P, and K addition experiment (40 m x 40m plots; n=4) in an AMF dominated, old (>200 yr), secondary, tropical forest. Previous research has shown co-limitation by N, P, and K, but the strongest plant growth responses were obtained with K additions. We analyzed the AMF community using 454 pyrosequencing of the ribosomal small subunit (SSU) on both soils and the roots of the 6 dominant AMF tree species. Additionally, we used the AMF-specific neutral lipid fatty acid (NLFA) biomarker as a measure of AMF biomass. Both AMF biomass and community structure were altered by nutrient additions. AMF biomass in soil was reduced

    Accurate estimation of aboveground forest biomass (AGB) and its dynamics is of paramount importance in understanding the role of forest in the carbon cycle and the effective implementation of climate change mitigation policies. LiDAR is currently the most accurate technology for AGB estimation. LiDAR metrics can be derived from the 3D point cloud (echo-based) or from the canopy height model (CHM). Different sensors and survey configurations can affect the metrics derived from the LiDAR data. We evaluate the ability of the metrics derived from the echo-based and CHM data models to estimate AGB in three different biomes, as well as the impact of point density on the metrics derived from them. Our results show that differences among metrics derived at different point densities were significantly different from zero, with a larger impact on CHM-based than echo-based metrics, particularly when the point density was reduced to 1 point m -2 . Both data models-echo-based and CHM-performed similarly well in estimating AGB at the three study sites. For the temperate forest in the Sierra Nevada Mountains, California, USA, R 2 ranged from 0.79 to 0.8 and RMSE (relRMSE) from 69.69 (35.59%) to 70.71 (36.12%) Mg ha -1 for the echo-based model and from 0.76 to 0.78 and 73.84 (37.72%) to 128.20 (65.49%) Mg ha -1 for the CHM-based model. For the moist tropical forest on Barro Colorado Island, Panama, the models gave R 2 ranging between 0.70 and 0.71 and RMSE between 30.08 (12.36%) and 30.32 (12.46) Mg ha -1 [between 0.69-0.70 and 30.42 (12.50%) and 61.30 (25.19%) Mg ha -1 ] for the echo-based [CHM-based] models. Finally, for the Atlantic forest in the Sierra do Mar, Brazil, R 2 was between 0.58-0.69 and RMSE between 37.73 (8.67%) and 39.77 (9.14%) Mg ha -1 for the echo-based model, whereas for the CHM R 2 was between 0.37-0.45 and RMSE between 45.43 (10.44%) and 67.23 (15.45%) Mg ha -1 . Metrics derived from the CHM show a higher dependence on point density than metrics

    Full Text Available As principais causas de inflamação pancreática no mundo são a litíase biliar e o alcoolismo crônico. Admite-se que 10 a 30% das pancreatites agudas sejam idiopáticas. Sugere-se que parte destas são causadas por microlitíase ou barro biliar, identificados pela presença de microcristais no sedimento biliar. Neste estudo, realizou-se análise microscópica da bile obtida por colangiopancreatografia endoscópica, em pacientes com pancreatite aguda idiopática, pancreatite aguda biliar e pancreatite crônica alcoólica - 20 em cada grupo. Pacientes com pancreatite aguda idiopática e microcristais na bile foram submetidos a colecistectomia. Naqueles inaptos à cirurgia efetuou-se esfincterotomia endoscópica ou tratamento com ácido ursodesoxicólico. Pacientes com pancreatite aguda idiopática sem cristais não receberam tratamento específico. A prevalência de microcristais biliares em pacientes com pancreatite aguda idiopática (75% e pancreatite aguda biliar (90% foi significativamente maior que naqueles com pancreatite crônica alcoólica (15%. A detecção de microcristais apresentou sensibilidade de 90%, especificidade de 85%, valor preditivo positivo de 85,7%, valor preditivo negativo de 89,4% e acurácia de 87,5% em identificar pancreatite de origem biliar. Nos pacientes com pancreatite aguda idiopática recurrente, cursando com microcristais, houve redução significante dos episódios de pancreatite após tratamento específico. No seguimento deste grupo durante 23,3 meses, recidiva ocorreu apenas naqueles que apresentavam "fator biliar persistente" (coledocolitíase ou microcristais. Todos os pacientes com pancreatite aguda idiopática submetidos a colecistectomia apresentavam colecistite crônica, e microlitíase foi observada em um paciente. No seguimento ultra-sonográfico, colelitíase foi detectada em um dos casos. No subgrupo de cinco pacientes com pancreatite aguda idiopática sem microcristais houve uma recidiva. Estudo

La arquitectura de los nidos fue similar para las cuatro especies: celdas de cría ubicadas linealmente, una detrás de la otra separadas por tabiques de barro, como es habitual en otras especies del subgénero Trypargilum. El 48% de los nidos presentó celda vestibular, mientras que sólo dos nidos presentaron celdas intercalares. El ancho de los tabiques y el largo de las celdas de cría difirió entre las especies y estuvo relacionado con el tamaño de las avispas que emergieron. Así mismo, el diámetro del nido-trampa estuvo directamente relacionado con el tamaño corporal promedio de las especies de mayor y menor tamaño. La mortalidad debida a parasitoides (Eulophidae; Melittobia sp. fue similar para las cuatro especies, mientras que la causada por cleptoparásitos (Chrysididae fue mayor en T. lactitarse. No fue posible relacionar la presencia de celda vestibular con la mortalidad debida a enemigos naturales para ninguna de las especies. La familia de arañas más frecuentemente utilizada como presa fue Araneidae.

  10. Community patterns of tropical tree phenology derived from Unmanned Aerial Vehicle images: intra- and interspecific variation, association with species plant traits, and response to interannual climate variation

    Phenology is a key life history trait of plant species and critical driver of ecosystem processes. There is strong evidence that phenology is shifting in temperate ecosystems in response to climate change, but tropical forest phenology remains poorly quantified and understood. A key challenge is that tropical forests contain hundreds of plant species with a wide variety of phenological patterns, which makes it difficult to collect sufficient ground-based field data to characterize individual tropical tree species phenologies. Satellite-based observations, an important source of phenology data in northern latitudes, are hindered by frequent cloud cover in the tropics. To quantify phenology over a large number of individuals and species, we collected bi-weekly images from unmanned aerial vehicles (UAVs) in the well-studied 50-ha forest inventory plot on Barro Colorado Island, Panama. The objective of this study is to quantify inter- and intra-specific responses of tropical tree leaf phenology to environmental variation over large spatial scales and identify key environmental variables and physiological mechanisms underpinning phenological variation. Between October 2014 and December 2015 and again in May 2015, we collected a total of 35 sets of UAV images, each with continuous coverage of the 50-ha plot, where every tree ≥ 1 cm DBH is mapped. UAV imagery was corrected for exposure, orthorectified, and then processed to extract spectral, texture, and image information for individual tree crowns, which was then used as inputs for a machine learning algorithm that successfully predicted the percentages of leaf, branch, and flower cover for each tree crown (r2=0.76 between observed and predicted percent branch cover for individual tree crowns). We then quantified cumulative annual deciduousness for each crown by fitting a non-parametric curve of flexible shape to its predicted percent branch time series and calculated the area under the curve. We obtained the species

    Con la insistencia que le es característica, el Académico José Félix Patiño nos reitera, o mejor, nos repica una vez más, en esta Academia, sobre la importancia de lo que él llama el nuevo paradigma, el de la informática, en la formación y el desempeño del médico contemporáneo. Creo que se me ha escogido a mí para ser su comentarista por haber sido la única persona que, en el curso de 15 años, lo ha acompañado solidariamente (aunque a veces nos separen distancias físicas y hasta profesionales verdaderamente anchurosas en lo esencial de esta idea, desde cuando fundamos, en 1981, el programa «FEPAFEM-COLCIENCIAS-OFA» de Informática Biomédica que desde entonces recibió el nombre de INFORMED.
    El fue el primero, quizás el único, que captó, en un momento determinado, las perspectivas que abría a la enseñanza y a la investigación médicas el primer programa de computador «en línea», abierto por la National Library of Medicine de los Estados Unidos (llamado desde entonces MEDLARSMEDLINE y lo que podría lograr de él Colombia y Latinoamérica, dadas incluso nuestras precarias comunicaciones y la inexistencia, por entonces entre nosotros, de los computadores personales. A esa visión pionera y a esa persistencia en una idea realizada fructíferamente, debe rendírsele reconocimiento, admiración y homenaje.
    Thomas Kuhn, en su libro «La estructura de las revoluciones científicas»! ha dicho que éstas se cumplen, justamente, mediante el establecimiento de nuevos paradigmas que reemplazan a otros ya decadentes u obsoletos.

    Full Text Available Plasticity and the grain-size distribution of the raw material used to make structural bricks and roof tiles are very important to the production process. These two parameters and the mineral composition will define the quality and properties of the final product: color, mechanical resistance, water absorption, cracks, swell and shrink during drying and firing the ceramic pieces etc. In the Brazilian ceramic industry it is very common to mix together two or more different kinds of raw material to achieve the ceramic mass with the desired grain-size distribution. The objective of this work was to characterize the raw material collected at the floodplains of the Paraná and Paranapanema Rivers and the ceramic mass used by the ceramic industry in western São Paulo State, Brazil. Particle size distribution, organic matter and X-ray diffraction were used to study this material. The textural analysis indicates that the raw materials have the clay fraction ranging from 38.2% to 66.3%, the silt from 22.2% to 49.7% and the sand from 3.1% to 34.1%. The results indicate that all mixed raw materials have more clay in its composition than would be necessary. The organic matter ranges from 5 to 7%. All samples have kaolinite and many of them have smectites, HIV and mica. Gibbsite, iron and titanium oxides, and quartz are also identified. One of the samples (yellow is rich in goethite.A plasticidade e a granulometria da massa cerâmica são dois parâmetros importantes para o processo de produção de tijolos e telhas.

    Atendimento, e na imagem positiva que é diferente do que as pessoas estavam acostumadas. De acordo com Camargos e Dias (2003 apud Thompson Jr. e Strickland III, 2000, pode-se definir estratégia como sendo um “conjunto de mudanças competitivas e abordagens comerciais que os gerentes executam para atingir o melhor desempenho da empresa. ” Junto a esse conceito, encontra-se o Marketing, que é utilizado como uma estratégia das empresas para serem bem vistas no mercado e por ele, chamar a atenção de seus clientes. Ele faz a ligação da empresa/produto com o cliente, visando chamar a atenção para o que está sendo oferecido. Podemos observar isso com a observação feita durante II Simpósio de Excelência em Gestão e Tecnologia – SEGeT’2005, onde foi descrito que “O marketing é uma das ferramentas da administração de empresas e dos negócios, e é fortemente conhecido e aplicado, na maioria das vezes, em processos de troca, com o fim de lucro. ” Além da proeminência do Marketing e da necessidade de uma Gestão que seja estratégica, o que veio para ajudar no processo comunicacional denomina-se como Design Gráfico que tem como objetivos: criar e desenvolver projetos tanto empresarial, como social, utilizando os meios gráficos para a resolução de problemas. O termo Design nasceu junto com a revolução industrial que ocorreu na Inglaterra quando houve uma revolução no modo de produção e começou, séculos mais tarde, a dar origem aos produtos com projetos específicos em grande escala (Fordismo. Barros (2013 em seu artigo sobre o que é Design Gráfico, documenta que “A ICOGRADA (Internacional Council of Grafic Design Associations afirma que o Design Gráfico é uma atividade técnica de análise, organização e métodos de apresentação de soluções visuais para problemas de comunicação. ” Com isso pode-se notar que há uma interdisciplinaridade necessária na tríade: Gestão Estratégica, Marketing e Design Gráfico - principalmente

    La ciudad de los Santos Reyes
    La guerra civil había diezmado las ganaderías de la rica provincia y la población entera pagaba con creces el horrendo pecado de la contienda fratricida. Muchas familias, antes en la holganza arrostraban con estoicismo pobreza vergonzante. Se caía a pedazos la antigua ciudad colonial, cerebro y corazón de extenso territorio. La propia plaza mayor mostraba solares que eran otros tantos estigmas de la situación aflictiva.

    Como el techo se había hundido en algo más de la mitad, por la vasta tronera la iglesia parroquial miraba realmente al cielo, exponiendo a la intemperie el muñón acusador de la torre casi a ras de piso. El espectáculo del templo era lastimoso. Los muros aparecían carcomidos por los alisios y las lluvias torrenciales, e igual las altas columnas talladas en troncos de árboles seguramente centenarios. Los altares, obra auténtica de la artesanía nativa, no ostentaban ya el brillo del dorado.

    En el piso, de anchas baldosas de barro cocido medio se hundían las lápidas de mármol que contaban el breve tránsito por este mundo de quienes fueran personas influyentes en la región.

    En la calle principal, en otros tiempos consagrada al Rey, menudeaban también las ruinas y, siguiendo en dirección al cementerio, podían descubrirse en un buen trecho los cimientos de construcciones desaparecidas, que por su disposición y tamaño proclamaban la fortuna de quienes las habitaran. Los conventos de Franciscanos y Dominicos yacían por tierra, convertidos en informe amontonamiento de escombros, igual que la mayoría de las casas de habitación que los rodeaban.

    Full Text Available ResumenLa acumulación material es uno de los signos más identificables de la pobreza. El pobre vive apegado a la tierra, esa es su única posesión y a partir de ella construirá sus refugios, sus habitaciones, sus utensilios. Las construcciones de arcilla, de barro, moldeadas con gran abundancia de materia  se encuentran en los poblados primitivos, pero cualquier situación marcada por la extrema pobreza lo estará también por las acumulaciones de material. Resulta inimaginable una situación de pobreza que no implique la acumulación de materia y esto es particularmente evidente en las sociedades desarrolladas, donde un mendigo es reconocible por su montaña de ropas, calzado o enseres de todo tipo.Resulta, sin embargo, significativo que en los discursos de los ideólogos de la modernidad, la identificación de ésta con el advenimiento de una sociedad sin clases venga acompañada de una apelación a la pobreza, una nueva pobreza fría y sobria, propia de una habitación humana abierta y transparente, casi desnuda, e igualitaria para todos los hombres sin distinción de clases sociales. Así, la pobreza moderna estaría ligada al material, a los nuevos materiales, pero no es una condición impuesta, sino elegida, o al menos aceptada como inevitable por el nuevo hombre.La convivencia entre una pobreza de la acumulación material y una pobreza de ascetismo y renuncia es un hecho tanto en los discursos como en las obras de las vanguardias del siglo XX. La acumulación de materia informe y trabajada manualmente tiene lugar al mismo tiempo que la exhibición de la desnudez y la frialdad de los materiales producidos por la industria.  Y en ambos casos, se apela a la pobreza como última referencia para las obras que tratan de ser una expresión fiel de las aspiraciones de su época.Palabras clavemateria, pobreza, material, acumulación, modernidad, sociedadAbstractAccumulation of matter is one of the most recognizable signs of poverty.

    Full Text Available Custodópolis é um bairro da cidade de Campos dos Goytacazes/RJ estigmatizado por localizar-se do outro lado do Rio Paraíba do Sul. Ocupado por uma população vulnerável ante a pobreza em suas dimensões econômicas, de capital social, capital humano, de proteção e de habitat (BUSSO, 2002, p.12. Estas dimensões conjugadas marcam o bairro de sua origem aos dias atuais. O objetivo é resgatar esse percurso, pela via habitacional e de entorno, nas condições de vulnerabilidade e risco socioambiental. Para o alcance desse objetivo utilizou-se os recursos metodológicos de Observação Direta (com registro em diário de campo e uso de fotografia, Fonte Documental e Entrevistas Semiestruturadas (com antigos e atuais moradores. Os resultados apontaram para trajetória de precarizações. Sobre a origem do bairro não há precisão, mas na memória de antigos moradores, se remete as décadas de vinte ou trinta do século passado. O lugar foi pouco a pouco sendo ocupado por cortadores de cana, que o transformaram em ponto de encontro na espera de caminhões que os levassem para as lavouras da região. Para atendimento a essa demanda foi montada uma vendinha e aos poucos tais trabalhadores se apropriaram do território e improvisaram suas casas no meio do mato com materiais como barro, bambu, folhas de palmeira ou sapé. Na falta de telha usavam palha. Vista do alto parecia uma “Cidade de Palha”, denominação antiga do local. No seu entorno havia brejo e lagoa que cederam espaço para canaviais. Não havia ruas, mas trilhas. Nem luz só lamparina. A água era de cacimba, os muros de gaiolinhas (tipo de planta, as camas de pau, os fogões a lenha. O proprietário das terras era um médico e político chamado Custódio Siqueira que as transformou em lotes para venda e, em sua homenagem, o bairro passou a ser chamado Custodópolis. Na travessia do rural-urbano o bairro experimentou melhorias, através da oferta pública de iluminação,
