    Full Text Available O objetivo deste artigo, voltado para a criação poética de Manoel de Barros, é focalizar o conceito da obra de arte como jogo. Escolhemos Manoel de Barros, porque o lúdico, a brincadeira e o humor estão sempre presentes em sua obra. A escolha dos dados, o encaixe de palavras escolhidas a dedo, no eixo paradigmático, formam um caleidoscópio, mostrando novas estruturas, deixando explícito o desejo de brincar com os elementos linguísticos e da natureza. Para este trabalho, escolhemos, para análise, pequenos poemas semelhantes aos haicais japoneses e outros menores ainda, com dois ou até um verso apenas. Contaremos, nesta pesquisa, com a ajuda de teóricos como Johan Huizinga, Ezra Pound, Octavio Paz, Lévi-Strauss, Olga Savary e Alfredo Bosi.

    2007-01-01

    The modulation of bandgap and HOCO/LUCO energies of conjugated polymers by copolymerization or by incorporation of electron withdrawing/releasing groups is studied. The study was conducted by band structure calculation applying density functional theory with generalized gradient approximation. The polymers and copolymers were modeled as 1D infinite system with periodical boundary condition along the molecular direction. It is concluded that the bandgap and HOCO/LUCO energies of conjugated polymers depend on both electron withdrawing/releasing effects and non-bonding interaction between a side group and the conjugated systems.

    This paper reported on the use of shading and lighting control algorithms at the P.E. Trudeau airport in Montreal. The airport has several perimeter zones with large glazed facades that receive excessive solar gains throughout the year. These facades were shaded by motorized shades operated manually by the airport personnel. As such, the building did not have efficient solar protection and extra air-conditioning was needed. Several light sensors were placed in strategic positions for monitoring the daylighting performance during variable weather conditions. Control algorithms for efficient shading and lighting operation were then developed using correlations between illuminance sensor signals. The sensors were used to monitor interior daylight levels under different sky conditions and shade positions. Reliable correlations were derived between ceiling and work plane illuminance, which were used to develop control schemes for shading and lighting operation. This paper also included simulation results for the potential energy savings due to reduced lighting and cooling energy demand. It was concluded that the shades close and prevent glare while still providing some view to the outdoors. The lighting energy savings will be significant because of the large glass areas and solar exposure throughout the day for all seasons. 9 refs., 3 tabs., 11 figs.

    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.

    2001-01-01

    Full Text Available Este é um estudo sobre gênero na produção artística de peças de cerâmica em algumas comunidades de artesãos do Vale do Jequitinhonha, Minas Gerais, onde tradicionalmente apenas as mulheres chamadas "paneleiras" praticavam esse ofício, que era transmitido de mãe para filha. Naquela região, assim que a arte do barro se tornou uma fonte alternativa de renda, vários homens decidiram entrar para o ofício. A entrada de homens na arte do barro provocou reconfigurações nas relações de gênero. Um ponto muito importante a ser observado aqui é que apesar de tradicionalmente transmitida por mulheres e pela ação feminina, a arte do barro tem incorporado valores de masculinidade: ao se aproximarem de um ofício tradicionalmente feminino, os homens passaram a retirar dele recursos simbólicos de representação de masculinidade.

    Full Text Available

    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.

    Full Text Available El 12 de Enero de 2010 un flujo de barro afectó un predio de esparcimiento con piletas de aguas termales en la localidad de Termas de Reyes, provincia de Jujuy. Este evento dejó 87 heridos y produjo grandes daños materiales. Las lluvias fueron las desencadenantes del movimiento del material a través de la quebrada del arroyo del Comedero. El depósito del flujo estuvo constituido por casi el 70% de grava, 20% de arena y 10% de limo arcilla y transportó trozos de materia orgánica y bloques mayores a 1 m³. Debido a la plasticidad del material, se lo clasificó como flujo de barro. La velocidad del movimiento se calculó usando un método empírico, coincidiendo su resultado con otros obtenidos en eventos cercanos. El volumen fue medido directamente en el campo, y calculado a través de ecuaciones enunciadas para flujos similares. Según los registros históricos de los depósitos de diferentes eventos ocurridos en la quebrada del arroyo del Comedero, esta se ubica en un rango de probabilidad muy alta de que se produzcan flujos. Con respecto a la clasificación de la magnitud del flujo de barro sobre el río Reyes, este pertenece a la clase con consecuencias potenciales de destrucción parcial de poblados, infraestructura de rutas y puentes, y bloqueo de quebradas. Los datos de velocidad, volumen y frecuencia calculados en este trabajo, que forman parte de la Carta de Peligrosidad Geológica Salta del SEGEMAR, son necesarios para el mapeo de peligrosidad, la programación de obras de infraestructura y la planificación territorial.

    Full Text Available Electing the book Memórias inventadas: a infância, by Brazilian poet Manoel de Barros, from the state of Goiás, the article intends to observe memory and as- sess the mechanisms through which it operates. From the basic assumption that memory is imagination, we search the theoretical support of the Phenomenology studies of Gaston Bachelard, relevantly in one of his last texts, which is dedicated to the examination of daydreaming and daydreaming about childhood. At the same time, we highlight the face of referential metapoetry as a focus of radiaton of those memories.

    2014-11-04

    The article analyzes how the process of the professionalization of physicians in São Paulo related to healthcare policy under the administration of São Paulo governor Adhemar de Barros (1947-1951) during a period of broad change in the realm of health known by São Paulo physicians as the "socialization of medicine." Medical professionalism confronted certain ambivalences under this populist administration, including doctors' struggle to achieve pay equal to that of state public attorneys; the establishment of a state health department; and some contradictory ties between the area of health under Adhemar and the professional ideology and organization of medicine in São Paulo. The article undertakes a more in-depth analysis of the ideological manifestations of important leaders in the state's medical community.

    2015-12-01

    Barro Colorado Island (BCI), Panama, may be the most studied tropical forest in the world. A 1,560-hectare island created by the flooding of the Panama Canal, BCI became a nature reserve and biological research station in 1923. Contemporaries saw the island as an "ark" preserving a sample of primeval tropical nature for scientific study. BCI was not simply "set aside," however. The project of making it a place for science significantly reshaped the island through the twentieth century. This essay demonstrates that BCI was constructed specifically to allow long-term observation of tropical organisms--their complex behaviors, life histories, population dynamics, and changing species composition. An evolving system of monitoring and information technology transformed the island into a living scientific "archive," in which the landscape became both an object and a repository of scientific knowledge. As a research site, BCI enabled a long-term, place-based form of collective empiricism, focused on the study of the ecology of a single tropical island. This essay articulates tropical ecology as a "science of the archive" in order to examine the origins of practices of environmental surveillance that have become central to debates about global change and conservation.

  5. 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

    Few data are available about the regional or local extinction of tropical butterfly species. When confirmed, local extinction was often due to the loss of host-plant species. We used published lists and recent monitoring programs to evaluate changes in butterfly composition on Barro Colorado Island (BCI, Panama) between an old (1923–1943) and a recent (1993–2013) period. Although 601 butterfly species have been recorded from BCI during the 1923–2013 period, we estimate that 390 species are currently breeding on the island, including 34 cryptic species, currently only known by their DNA Barcode Index Number. Twenty-three butterfly species that were considered abundant during the old period could not be collected during the recent period, despite a much higher sampling effort in recent times. We consider these species locally extinct from BCI and they conservatively represent 6% of the estimated local pool of resident species. Extinct species represent distant phylogenetic branches and several families. The butterfly traits most likely to influence the probability of extinction were host growth form, wing size and host specificity, independently of the phylogenetic relationships among butterfly species. On BCI, most likely candidates for extinction were small hesperiids feeding on herbs (35% of extinct species). However, contrary to our working hypothesis, extinction of these species on BCI cannot be attributed to loss of host plants. In most cases these host plants remain extant, but they probably subsist at lower or more fragmented densities. Coupled with low dispersal power, this reduced availability of host plants has probably caused the local extinction of some butterfly species. Many more bird than butterfly species have been lost from BCI recently, confirming that small preserves may be far more effective at conserving invertebrates than vertebrates and, therefore, should not necessarily be neglected from a conservation viewpoint.

    Full Text Available Despite the importance of tropical forests to the global carbon cycle, ecological controls over landscape-level variation in live aboveground carbon density (ACD in tropical forests are poorly understood. Here, we conducted a spatially comprehensive analysis of ACD variation for a mainland tropical forest – Barro Colorado Island, Panama (BCI – and tested site factors that may control such variation. We mapped ACD over 98% of BCI (~1500 ha using airborne Light Detection and Ranging (LiDAR, which was well-correlated with ground-based measurements of ACD in Panamanian forests of various ages (r2 = 0.77, RMSE = 29 Mg C ha−1, P < 0.0001. We used multiple regression to examine controls over LiDAR-derived ACD, including slope angle, bedrock, soil texture, and forest age. Collectively, these variables explained 14% of the variation in ACD at 30-m resolution, and explained 33% at 100-m resolution. At all resolutions, slope (linked to underlying bedrock variation was the strongest driving factor; standing carbon stocks were generally higher on steeper slopes, where erosion rates tend to exceed weathering rates, compared to gentle slopes, where weathering in place produces deep, oxic soils. This result suggests that physiography may be more important in controlling ACD variation in Neotropical forests than currently thought. Although BCI has been largely undisturbed by humans for a century, past land-use over approximately half of the island still influences ACD variation, with younger forests (80–130 years old averaging ~15% less carbon storage than old-growth forests (>400 years old. If other regions of relatively old tropical secondary forests also store less carbon aboveground than primary forests, the effects on the global carbon cycle could be substantial and difficult to detect with satellite monitoring.

    Full Text Available Los farmacéuticos y productos de cuidado personal (PPCPs pertenecen al grupo contaminantes emergentes, su riego ambiental no se había detectado hasta hace una década. 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.

    The Niquelandia Complex comprises two main superposed sequences dipping westward: the lower (LS), at the eastern, and the upper (US), at the western part of the body. The Complex is either interpreted as a single body, or as two distinct unrelated layered massifs. New SHRIMP U-Pb determinations on igneous zircon grains of anorthosites from Niquelandia US and from the upper portion of the Barro Alto Complex indicate crystallization ages of 833 {+-} 21 Ma and 733 {+-} 25 Ma, respectively, thus supporting Cryogenian Neoproterozoic ages for the igneous crystallization of the US unit of Niquelandia and for the Barro Alto anorthosites.

    Transmission of pathogens from domestic animals to wildlife populations (spill-over) has precipitated local wildlife extinctions in multiple geographic locations. Identifying such events before they cause population declines requires differentiating spillover from endemic disease, a challenge complicated by a lack of baseline data from wildlife populations that are isolated from domestic animals. We tested sera collected from 12 ocelots (Leopardus pardalis) native to Barro Colorado Island, Panama, which is free of domestic animals, for antibodies to feline herpes virus, feline calicivirus, feline corona virus, feline panleukopenia virus, canine distemper virus, and feline immunodeficiency virus (FIV), typically a species-specific infection. Samples also were tested for feline leukemia virus antigens. Positive tests results were only observed for FIV; 50% of the ocelots were positive. We hypothesize that isolation of this population has prevented introduction of pathogens typically attributed to contact with domestic animals. The high density of ocelots on Barro Colorado Island may contribute to a high prevalence of FIV infection, as would be expected with increased contact rates among conspecifics in a geographically restricted population.

  16. A new basal sauropodomorph (Dinosauria: Saurischia from Quebrada del Barro Formation (Marayes-El Carrizal Basin, northwestern Argentina.

    Directory of Open Access Journals (Sweden)

    Cecilia Apaldetti

    Full Text Available 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

    This study assessed the effect of breed and diet on carcass composition, particularly fat partitioning, and meat quality in young bulls. An experiment with forty young bulls from two phylogenetically distant Portuguese bovine breeds, Alentejana and Barrosã, fed two diets with different maize silage to concentrate ratios, but isoenergetic and isonitrogenous, was carried out until the animals reached 18 months of age. In the longissimus lumborum muscle, Barrosã bulls fed the low silage diet had the highest intramuscular fat (IMF) content. Bulls fed the low silage diet also had the highest IMF content in the semitendinosus muscle. Diet determined the proportions of total visceral fat and individual fat depots. Under these experimental conditions, it was shown that the genetic background is a major determinant of carcass composition and meat quality, and that the dietary differences studied had limited effect on carcass composition.

    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.

  1. Lutzomyia sand fly diversity and rates of infection by Wolbachia and an exotic Leishmania species on Barro Colorado Island, Panama.

    Full Text Available BACKGROUND: 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. METHODOLOGY AND FINDINGS: 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

    Full Text Available El 12 de Enero de 2010 un flujo de barro afectó un predio de esparcimiento con piletas de aguas termales en la localidad de Termas de Reyes, provincia de Jujuy. Este evento dejó 87 heridos y produjo grandes daños materiales. Las lluvias fueron las desencadenantes del movimiento del material a través de la quebrada del arroyo del Comedero. El depósito del flujo estuvo constituido por casi el 70% de grava, 20% de arena y 10% de limo arcilla y transportó trozos de materia orgánica y bloques mayores a 1 m³. Debido a la plasticidad del material, se lo clasificó como flujo de barro. La velocidad del movimiento se calculó usando un método empírico, coincidiendo su resultado con otros obtenidos en eventos cercanos. El volumen fue medido directamente en el campo, y calculado a través de ecuaciones enunciadas para flujos similares. Según los registros históricos de los depósitos de diferentes eventos ocurridos en la quebrada del arroyo del Comedero, esta se ubica en un rango de probabilidad muy alta de que se produzcan flujos. Con respecto a la clasificación de la magnitud del flujo de barro sobre el río Reyes, este pertenece a la clase con consecuencias potenciales de destrucción parcial de poblados, infraestructura de rutas y puentes, y bloqueo de quebradas. Los datos de velocidad, volumen y frecuencia calculados en este trabajo, que forman parte de la Carta de Peligrosidad Geológica Salta del SEGEMAR, son necesarios para el mapeo de peligrosidad, la programación de obras de infraestructura y la planificación territorial.The January 12th 2010 mudflow in the Comedero stream, Termas de Reyes, province of Jujuy, affected a hot springs recreational area causing 87 wounded people and severe material damage.

    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.

    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.

Por otro lado, reflexionaremos en torno al papel subordinado de Luisa y su interiorización tanto del poder patriarcal como del rol de objeto y no sujeto de deseo. Las principales herramientas metodológicas de nuestro trabajo se desarrollarán desde una perspectiva de género.

    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.

    A highly efficient luminescence conversion light emitting diode (LUCO LED) was fabricated, using a commercial InGaN LED (460 nm) and 4- N, N-diphenyl-9-(4- tert-butylphenyl)-1,8-naphthalimide (DBN), dispersed in epoxy as the primary light source and LUCO material, respectively. The emission of very bright white light was observed at 20 mA, with CIE chromaticity coordinates of (0.32, 0.33) and conversion efficiency of 82%. The luminescent output of the LUCO LED decreased rapidly, but when the LUCO LED was prepared using DNB dispersed in poly(methyl methacrylate), it only decreased to about 67% of the initial value after 19 days of continual operation at 200 mA.

    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.

    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.

    Until recently, Quebec was the first to have regulated the practice of psychotherapy through law adopted in 2009. The law emerged following 30 years of efforts and inter-professional discussions that led to a consensus by an expert committee presided by Dr Jean-Bernard Trudeau in 2005. In this essay, Dr Jean-Bernard Trudeau, general practitioner, and two psychiatrist and psychologist colleagues, who have participated to the expert committee or have been involved more recently in the implementation of law no 21 in Quebec, relate the main landmarks and moments in the regulation of the practice in psychotherapy following this inter-professional consensus that was translated in the law 21. They relate particularly the last ten years that have led to the adoption of law 21 in 2009, following two parliamentary commission after the Trudeau report. They underline how the practice of psychotherapy is integrated in the professional system and submitted to strict regulation. It includes regulations for obtaining the license of psychotherapist and for maintaining competence. Guidelines emerging from continuous inter-professional discussions for the application of the law and of its regulation in the public and private sectors are produced by the Quebec Professions Office. The definition of psychotherapy that was reached by consensus is not limited to the treatment of mental disorders and is distinguished from other intervention in the area of human relations. Continuous training is mandatory and is implemented on one hand by the Order of the psychologists for the psychologists and other professionals practicing psychotherapy and on the other hand the College of physicians for physician practicing psychotherapy. The authors finally described the interdisciplinary advisory council for the practice of psychotherapy that the legislator has foreseen as an external mechanism to insure the conformity of regulation with the spirit of the law and to give opinions to the various

    Stable white-emitting down-converted LEDs are straightforwardly prepared by bulk polymerization of an organic dye doped polymethyl-methacrylate (PMMA) shell directly on top of a highly efficient commercial blue-emitting InGaN LED. Our optimized polymerization procedure allows for extending the form factor of achievable luminescence converter (LUCO) material beyond the conventional thin film form and to directly produce devices with light bulb design. The selected organic dyes, the blue-emitting Coumarin 30 and a red-emitting diketopyrrolopyrrole derivative, exhibit high compatibility with the free radical polymerization reaction of the PMMA matrix and ensure high stability of the final hybrid device. The control of both the thickness of the PMMA shell and the concentration of the dopant dyes allow for fine tuning of the emission color of the LUCO LED and to obtain white light with CIE chromatic coordinates x = 0.32 and y = 0.33, with rendering index as high as 80. This simple and versatile procedure is not dye-exclusive and is therefore extendable to other molecular systems for color-tunable efficient solid-state lighting sources.

    The molecular and crystal structure of the adduct NF3·BF3 was studied computationally using density functional theory. It shows that the adduct exists in the form of a complex but is not ionic. The heats of formation in the gas and the condensed phase of the adduct are −1266.09 and −1276.37 kJ·mol−1, respectively, which indicates that it is stable under atmospheric conditions. The crystal form belongs to 21/ space group. The calculated large band gap ( g) of the crystal proves that it is stable. The conduction band (LUCO) is mainly contributed by the orbital of N atom and the valence band (HOCO) from the orbital of F atom.

    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{sup -1} wet weight). The highest {sigma}DDT concentrations were measured in Brown-hooded Gulls (726 ng g{sup -1}). PCB levels were similar among the species (102-236 ng g{sup -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 ({sigma}OHa). 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.

    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.

    Just as a pistol shrimp stuns its prey by quickly closing its oversized claw to shoot out a shock-inducing, high-velocity jet of water, NanoMatrix, Inc., is sending shockwaves throughout the nanotechnology world with a revolutionary, small-scale fabrication process that uses powerful liquid jets to cut and shape objects. Emanuel Barros, a former project engineer at NASA s Ames Research Center, set out to form the Santa Cruz, California-based NanoMatrix firm and materialize the micro/nano cutting process partially inspired by the water-spewing crustacean. Early on in his 6-year NASA career, Barros led the development of re-flown flight hardware for an award-winning Spacelab project called NeuroLab. This project, the sixteenth and final Spacelab mission, focused on a series of experiments to determine the effects of microgravity on the development of the mammalian nervous system.

    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)

    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.

    Full Text Available En este trabajo se prueba la hipótesis de Barro mediante un modelo de vectores autorregresivos y multicointegración para la economía mexicana. La hipótesis de Barro se basa en los postulados de expectativas racionales, los cuales señalan que una expansión monetaria no tiene efectos reales a menos que sea sorpresa. Sin embargo, en función de los resultados, tanto la oferta de dinero anticipada como la no-anticipada tienen efectos reales en la economía mexicana. En este caso, el dinero es no-neutral. Las razones de esta no-neutralidad van desde las rigideces del sistema, las características particulares de la política monetaria, hasta la composición de la estructura de la economía mexicana.

    In this paper we present a neural oscillator model of stimulus response theory that exhibits quantum-like behavior. We then show that without adding any additional assumptions, a quantum model constructed to fit observable pairwise correlations has no predictive power over the unknown triple moment, obtainable through the activation of multiple oscillators. We compare this with the results obtained in de Barros (2013), where a criteria of rationality gives optimal ranges for the triple moment.

    2007-01-01

    The competitive binding of rare earth elements (REE) to humic acid (HA) and carbonates was studied experimentally at various pH and alkalinity values by combining ultrafiltration and inductively coupled plasma mass spectrometry techniques. The results show that the REE species occur as binary humate or carbonate complexes but not as ternary REE-carbonate-humate as previously proposed. The results also reveal the strong pH and alkalinity dependence of the competition as well as the existence of a systematic fractionation across the REE series. Specifically, carbonate complexation is at a maximum at pH 10 and increase with increasing alkalinity and with the atomic number of the REE (LuCO(3)>LaCO(3)). Modeling of the data using Model VI and recently published stability constants for complexation of REE by humic acid well reproduced the experimental data, confirming the ability of Model VI to accurately determine REE speciation in natural waters. This modeling also confirms the reliability of recently published stability constants. This work shed more light not only on the competition between carbonates and HA for REE complexation but also on the reliability of WHAM 6 and Model VI for calculating the speciation of REE with organic matter in alkaline organic-rich water.

  15. Converting HAZUS capacity curves to seismic hazard-compatible building fragility functions: effect of hysteretic models

    Science.gov (United States)

    Ryu, Hyeuk; Luco, Nicolas; Baker, Jack W.; Karaca, Erdem

    2008-01-01

    A methodology was recently proposed for the development of hazard-compatible building fragility models using parameters of capacity curves and damage state thresholds from HAZUS (Karaca and Luco, 2008). In the methodology, HAZUS curvilinear capacity curves were used to define nonlinear dynamic SDOF models that were subjected to the nonlinear time history analysis instead of the capacity spectrum method. In this study, we construct a multilinear capacity curve with negative stiffness after an ultimate (capping) point for the nonlinear time history analysis, as an alternative to the curvilinear model provided in HAZUS. As an illustration, here we propose parameter values of the multilinear capacity curve for a moderate-code low-rise steel moment resisting frame building (labeled S1L in HAZUS). To determine the final parameter values, we perform nonlinear time history analyses of SDOF systems with various parameter values and investigate their effects on resulting fragility functions through sensitivity analysis. The findings improve capacity curves and thereby fragility and/or vulnerability models for generic types of structures.

    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.

    Full Text Available Investment in education is an essential element for the economic growth of a country. Theory supports this argument with models that stress the individual and social benefits of education. Although the empirical literature shows ample consensus regarding the existence of positive individual returns to education, its impact on economic growth is, nevertheless, not clear. This paper applies panel data techniques to measure the effects of education on long-run economic growth, to the case of regional growth in Argentina. There are two major problems when estimating growth regressions: 1 individual effects are correlated with explanatory variables, and 2 simultaneity biases. To avoid these problems, a generalized method of moments (GMM estimator is used (Arellano and Bond, 1991; Caselli, Esquivel and Lefort, 1996. Two types of models were tested. Standard and human capital-augmented Solow models, and Barro specifications. The standard Solow model fit poorly in most cases. Likewise, the augmented Solow model presented wrong signs on most coefficients. However, education always showed a positive and significative impact on long-run growth. On the other hand, in a-la-Barro specifications always education present a positive and important impact on growth, using aggregate measures of education achievement levels, although using disaggregate measures of education the results were not so clear. It turns out that, depending on the empiric specification, secondary school and university education have an important effect on growth. Regarding convergence, the empirical evidence is mixed. Under certain specifications, GMM estimation finds strong evidence of convergence at a rather fast speed (around 5% per year, which is twice as fast as estimates using standard techniques for the US and Japan (Barro and Sala-i-Martin, 1995. However, when using more demanding specifications, the data does not support the conditional convergence hypothesis. Investment in

    Full Text Available «Prefabricated cane lathing» basically involves the use of frames of sawn timber, filled with round wattle, cane and strips of bamboo, all plaited together so that they can be placed and fixed in the frame without nails being required. Once these panels have been assembled and fixed in place to provide walls, they are covered with a mixture of mud and straw forming a primary layer, and finally, they are given a top layer using such material as mud, cement, plaster and other substances, depending on preferences, costs and climatic or other conditions to which the wall is to be exposed, or on the preferences of the user. A light roof is used for roofing, based on a wooden support structure and a covering made of cane and a mud cast packed with straw. For regions of high rainfall, planks of asbestos and cement, zinc or other materials are fixed over the mud cast.La «Quincha Prefabricada» consiste básicamente en el empleo de bastidores de madera aserrada, rellenados con cañizo redondo, caña brava, tiras de bambú, todos ellos colocados en el bastidor en forma trenzada para su auto fijación sin necesidad de usar clavos; estos paneles, después de ser montados y fijados en sitio constituyendo paredes, son revocados con barro mezclado con paja, formando una primera capa; y, finalmente, reciben una última capa de revoque utilizándose materiales como el barro, cemento, yeso u otros, dependiendo de las preferencias, costos, de las condiciones climatológicas u otras a las que estará expuesta la pared o de las preferencias del usuario. Como techado se emplea un techo liviano a base de una estructura portante de madera y cobertura de caña y torta de barro con paja. Para zonas de alta precipitación pluvial se fija, sobre la torta de barro, planchas de asbesto-cemento, planchas de zinc u otras.

  12. Expression of genes controlling fat deposition in two genetically diverse beef cattle breeds fed high or low silage diets

    Science.gov (United States)

    2013-01-01

    Background Both genetic background and finishing system can alter fat deposition, thus indicating their influence on adipogenic and lipogenic factors. However, the molecular mechanisms underlying fat deposition and fatty acid composition in beef cattle are not fully understood. This study aimed to assess the effect of breed and dietary silage level on the expression patterns of key genes controlling lipid metabolism in subcutaneous adipose tissue (SAT) and longissimus lumborum (LL) muscle of cattle. To that purpose, forty bulls from two genetically diverse Portuguese bovine breeds with distinct maturity rates, Alentejana and Barrosã, were selected and fed either low (30% maize silage/70% concentrate) or high silage (70% maize silage/30% concentrate) diets. Results The results suggested that enhanced deposition of fatty acids in the SAT from Barrosã bulls, when compared to Alentejana, could be due to higher expression levels of lipogenesis (SCD and LPL) and β-oxidation (CRAT) related genes. Our results also indicated that SREBF1 expression in the SAT is increased by feeding the low silage diet. Together, these results point out to a higher lipid turnover in the SAT of Barrosã bulls when compared to Alentejana. In turn, lipid deposition in the LL muscle is related to the expression of adipogenic (PPARG and FABP4) and lipogenic (ACACA and SCD) genes. The positive correlation between ACACA expression levels and total lipids, as well trans fatty acids, points to ACACA as a major player in intramuscular deposition in ruminants. Moreover, results reinforce the role of FABP4 in intramuscular fat development and the SAT as the major site for lipid metabolism in ruminants. Conclusions Overall, the results showed that SAT and LL muscle fatty acid composition are mostly dependent on the genetic background. In addition, dietary silage level impacted on muscle lipid metabolism to a greater extent than on that of SAT, as evaluated by gene expression levels of adipogenic and

    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.

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.

    2011-12-01

    Hurricanes and tropical storms (collectively known as tropical cyclones TCs) are regular events of varying magnitude and moderate frequency. These powerful and hazardous meteorological phenomena cause damages to natural and built areas all around the world. However, on the flip side, TCs provide a significant influx of freshwater resources to surface and subsurface reservoirs during the warm season and participate to the relief of drought conditions in several part of the world. Previously, a framework using remote-sensing data (MODIS EVI) was developed to characterize the spatial organization of vegetation disturbances and monitor vegetation recovery in the aftermath of land-falling hurricanes. Here, a distributed eco-hydrological model (Garcia-Quijano and Barros, 2005; Yildiz and Barros, 2007) is used to investigate the link between vegetation disturbance persistence and hydrological processes in pristine watersheds along the terrestrial tracks of hurricanes in 2004 and 2005. Model simulated gross primary production (GPP) over the Southeastern US before and after these two highly active hurricane seasons will be used to map EVI based vegetation disturbances to primary productivity changes.

    CERN Document Server

    Belabbas, A

    2006-12-01

    The subject of this dissertation consists in analyzing a recent proposition, advanced by C.C.Barros, in which the non gravitational interactions can affect the space-time metric as in gravity. In fact, in the context of the Schwarzschild solution, the hydrogen atom is described in a completely new way : instead of following the usual approach to describe the electron under the Coulomb potential by using the minimal coupling, the "proton-electron" interaction is rather incorporated in the metric. In this context, we reproduce in this dissertation the same equations as predicted in Dirac theory for the weak potential approximation. Contrary to the statement made by Barros, claiming that he brought an insignificant correction to the electron levels, at the end of our analysis, we assert that this new approach has the merit of reproducing the relativistic spectrum as known in the Dirac theory. These spectacular results incite us to wonder about the role of the Principle of Equivalence in the foundations of the ge...

    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.

    In Brazil economically important coal deposits occur in the southern part of the Paran?? Basin, where coal seams occur in the Permian Rio Bonito Formation, with major coal development in the states of Rio Grande de Sul and Santa Catarina. The current paper presents results on sequence stratigraphic interpretation of the coal-bearing strata, and petrological and geochemical coal seam characterization from the South Santa Catarina Coalfield, Paran?? Basin.In terms of sequence stratigraphic interpretation the precursor mires of the Santa Catarina coal seams formed in an estuarine-barrier shoreface depositional environment, with major peat accumulation in a high stand systems tract (Pre-Bonito and Bonito seams), a lowstand systems tract (Ponta Alta seam, seam A, seam B) and a transgressive systems tract (Irapu??, Barro Branco and Treviso seams).Seam thicknesses range from 1.70 to 2.39. m, but high proportions of impure coal (coaly shale and shaley coal), carbonaceous shale and partings reduce the net coal thickness significantly. Coal lithoypes are variable, with banded coal predominant in the Barro Branco seam, and banded dull and dull coal predominantly in Bonito and Irapu?? seams, respectively. Results from petrographic analyses indicate a vitrinite reflectance range from 0.76 to 1.63 %Rrandom (HVB A to LVB coal). Maceral group distribution varies significantly, with the Barro Branco seam having the highest vitrinite content (mean 67.5 vol%), whereas the Irapu?? seam has the highest inertinite content (33.8. vol%). Liptinite mean values range from 7.8. vol% (Barro Branco seam) to 22.5. vol% (Irapu?? seam).Results from proximate analyses indicate for the three seams high ash yields (50.2 - 64.2wt.%). Considering the International Classification of in-Seam Coals, all samples are in fact classified as carbonaceous rocks (>50wt.% ash). Sulfur contents range from 3.4 to 7.7 wt.%, of which the major part occurs as pyritic sulfur. Results of X-ray diffraction indicate the

    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.

    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.

Set between the late 1940s and 1964 - the year of Oticica Filho's death - the article discusses the history of Brazilian photography and how it relates to the history of art, as well as the issue of abstraction. By doing so, it shows how the history of modern Brazilian photography interacts with the concrete and neoconcrete art movements. In addition, the author offers a critical review of the texts written about these two photographers and their images as a means to determine their importance beyond the field of photography.

    Negative density dependence (NDD) of recruitment is pervasive in tropical tree species. We tested the hypotheses that seed dispersal is NDD, due to intraspecific competition for dispersers, and that this contributes to NDD of recruitment. We compared dispersal in the palm Attalea butyracea across a wide range of population density on Barro Colorado Island in Panama and assessed its consequences for seed distributions. We found that frugivore visitation, seed removal and dispersal distance all declined with population density of A. butyracea, demonstrating NDD of seed dispersal due to competition for dispersers. Furthermore, as population density increased, the distances of seeds from the nearest adult decreased, conspecific seed crowding increased and seedling recruitment success decreased, all patterns expected under poorer dispersal. Unexpectedly, however, our analyses showed that NDD of dispersal did not contribute substantially to these changes in the quality of the seed distribution; patterns with population density were dominated by effects due solely to increasing adult and seed density.

    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.

    2017-01-01

    One of the fundamental results used in observational cosmology is the distance duality relation (DDR), which relates the luminosity distance, DL , with angular diameter distance, DA , at a given redshift z . We employ the observed limits of this relation to constrain the coupling of axionlike particles (ALPs) with photons. With our detailed 3 D ALP-photon mixing simulation in standard Λ CDM universe and latest DDR limits observed in Holanda and Barros [Phys. Rev. D 94, 023524 (2016)]., 10.1103/PhysRevD.94.023524 we limit the coupling constant gϕ≤6 ×10-13 GeV-1(n/G ⟨B ⟩Mpc ) for ALPs of mass ≤10-15 eV . The DDR observations can provide very stringent constraint on ALPs mixing in the future. Also any deviation in DDR can be conventionally explained as photons decaying to axions or vice-versa.

    Studying animal movement and distribution is of critical importance to addressing environmental challenges including invasive species, infectious diseases, climate and land-use change. Motion sensitive camera traps offer a visual sensor to record the presence of a broad range of species providing location -specific information on movement and behavior. Modern digital camera traps that record video present new analytical opportunities, but also new data management challenges. This paper describes our experience with a terrestrial animal monitoring system at Barro Colorado Island, Panama. Our camera network captured the spatio-temporal dynamics of terrestrial bird and mammal activity at the site - data relevant to immediate science questions, and long-term conservation issues. We believe that the experience gained and lessons learned during our year long deployment and testing of the camera traps as well as the developed solutions are applicable to broader sensor network applications and are valuable for the ad...

    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.

    2006-05-01

    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.

    Full Text Available Nowadays, the world economies are rapidly moving towards being more Knowledge-based Economy (KBE and supporting the force of knowledge as a vital component of economic growth. This recent acceleration in the transition to Knowledge-based Economy in the world, has affected regional economic performance. In this paper, we surveyed the regional convergence in Knowledge-based Economy for selected Asia and pacific countries. We used a growth model in Barro and Sala-i-Martin framework (1995 for the period of 1995-2009. It includes a panel data set consisting of the annual growth rate of GDP per capita for selected Asia and pacific countries and a group of indicators that define the situation of Knowledge-based Economy in countries. The empirical results indicate that the absolute and the conditional convergence are not rejected for selected countries. The investigation on robustness of the model results confirms the existence of regional convergence for studied countries.

    Fuzzy logic was introduced by Zadeh in 1965. Since then, the importance of fuzzy logic has come increasingly to the present.There are many applications of fuzzy logic in the field of science and engineering, e.g. population dynamics (Barros), chaos control (Feng,Fradkov), computer programming (Giles), nonlinear dynamical systems (Hong), etc. The concept of intuitionistic fuzzy set, as a generalization of fuzzy logic, was introduced by Atanassov in 1986. Quite recently Park has introduced the concept of intuitionistic fuzzy metric space, and Saadati and Park studied the notion of intuitionistic fuzzy normed space. Intuitionistic fuzzy analogues of many concept in classical analysis was studied by many authors (Mursaleen, Rsaadati, Jebril, Dinda, etc.). The concept of statistical convergence was introduced by Fast. Mursaleen defined {\\lambda}-statistical convergence in Muhammed.

    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.

    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.

    Full Text Available Free-ranging ticks are widely known to be restricted to the ground level of vegetation. Here, we document the capture of the tick species Amblyomma tapirellum in light traps placed in the forest canopy of Barro Colorado Island, central Panama. A total of forty eight adults and three nymphs were removed from carbon dioxide–octenol baited CDC light traps suspended 20 meters above the ground during surveys for forest canopy mosquitoes. To our knowledge, this represents the first report of questing ticks from the canopy of tropical forests. Our finding suggests a novel ecological relationship between A. tapirellum and arboreal mammals, perhaps monkeys that come to the ground to drink or to feed on fallen fruits.

    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.

      本文通过将 Barro 和 Martin 的领导者-追随者模型扩展至包含外商投资部门,构建了技术差距对 FDI溢出影响的理论模型,并得出如下结论:外资企业通过技术溢出效应提高了东道国企业的生产效率,即 FDI 的技术溢出效应是存在的;对于存在不同程度技术差距的内外资企业,技术差距对 FDI 溢出效应的作用不同;当内外资企业技术差距过大时,外资企业技术水平的提高不会产生更显著的技术溢出,反而由于东道国企业难以吸收而抑制外资企业的技术溢出。%This paper extends Barro and Martin's leader-follower model to include the foreign-invested sector, and build the theoretical model of technology gap on FDI overflow effect. This paper draws the following conclusions: first, Foreign-funded enterprises raise production efficiency of the host countries through technical spillover effects; in the second place, the role of FDI spillovers is different between different degrees of technology gap.When technology gap between domestic and for-eign enterprises is too large, Technology gap suppresses technology spillover of foreign-funded enterprises because of the host country enterprises is difficult to absorb.

  8. Empirical Evidence of Fiscal Policy Impact on Endogenous Models of Economic Growth - the Case of Albania

    Directory of Open Access Journals (Sweden)

    Olta Milova

    2014-02-01

    Full Text Available According to Mankiw (2000, fiscal policy in major macroeconomic models adversely affects the behavior of private agents as consumers and firms and they affect economic growth through investment and savings decisions. Increasing government spending will increase the aggregate demand for goods and services and money demand in the money market leading to an increase of interest rates while markets tend towards equilibrium. The increased interest rates affect negatively the level of private investment. To assess the effect of fiscal policy on economic growth generally are used the endogenous growth models, which include technological progress as an integrated part of this model. These models were called endogenous because they were taking into account long-term economic growth and were using endogenous mechanisms to explain its main source which is the technological progress. Endogenous growth models developed by Barro (1990, Mendosa, Milesi-Ferreti and Asea (1997 or even by other economists, predict that the fiscal policy can affect the level of product and the long run economic growth. This conclusion is analysed in the theory of Barro (1990, which extends the model by including the fiscal policy. The Barro’s model is the model used in this paper to analyse the effect of the fiscal policy on economic growth in the case of Albania. The empirical work shows that all the variables, except inflation which according to theoretical expectations should have a negative effect, affect positively the economic growth. This positive relation between these variables can be explained by investments in infrastructure and other priority sectors that the government has done during all this period.

  9. What is the cause of the decline in maternal mortality in India? Evidence from time series and cross-sectional analyses.

    2014-05-01

    Summary Studies on the causes of maternal mortality in India have focused on institutional deliveries, and the association of socioeconomic and demographic factors with the decline in maternal mortality has not been sufficiently investigated. By using both time series and cross-sectional data, this paper examines the factors associated with the decline in maternal mortality in India. Relative effects estimated by OLS regression analysis reveal that per capita state net domestic product (-1.49611, pmortality rate and total fertility rate (0.11755, pmaternal mortality ratio in India. The Barro-regression estimate reveals that improvements in economic and demographic conditions such as growth in state income (β=0.35020, pmaternal mortality ratio in India than institutional deliveries (β=0.00305). The negative β-coefficient (β=-0.69578, pmaternal mortality ratio on change in maternal mortality ratio in the Barro-regression model, indicates a greater decline in maternal mortality ratio in laggard states compared with advanced states. Overall, comparing the estimates of relative effects, the socioeconomic and demographic factors have a stronger statistically significant association with the maternal mortality ratio than institutional deliveries. Interestingly, the weak association between 'increase in institutional deliveries' and 'decline in maternal mortality ratio' suggests that merely increasing deliveries alone will not help in ensuring maternal survival in India. Quality of services provided by the health facility, birth preparedness and avoiding delay in reaching health facility are also important. Deliveries in health facilities will not necessarily translate into increased survival chances of mothers unless women receive full antenatal care services and delays in reaching health facility are avoided.

    Full Text Available OBJETIVO: Evaluar los niveles de plomo en sangre de niños morelenses y sus factores de exposición. MATERIAL Y MÉTODOS: Estudio transversal para analizar, por voltametría anódica, los niveles de plomo en sangre de 232 niños de 1 a 12 años de edad, que acudieron de junio a octubre de 1996 al Hospital del Niño Morelense de Cuernavaca, Morelos, México. Los factores de exposición se indagaron por cuestionario. El valor de concentración de plomo se transformó al logaritmo natural; se estimó la razón de momios para algunos factores de exposición que se incorporaron a un modelo de ANOVA. RESULTADOS: Se reclutaron 232 niños (50% mujeres; 73% residentes en Cuernavaca. La media geométrica de plomo en sangre fue 6.7 µg/dl; 29.7% rebasaron los 10 µg/dl; 66% tenían antecedente de cocinar alimentos en barro vidriado; 36% de almacenar alimentos, y 19%, consumo de líquidos en ese material. CONCLUSIONES: Los niveles encontrados son similares a los reportados en otras poblaciones pediátricas mexicanas en los últimos años. Entre los principales factores de exposición destacan el uso de barro vidriado para consumo de alimentos o líquidos y la intensidad del tráfico donde viven. 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.

    Full Text Available This article examines the tools, approaches, collaboration, and findings of the Web Archives for Historical Research Group around the capture and analysis of about 4 million tweets during the 2015 Canadian Federal Election. 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. Our analytics included: breaking tweet text down by day to track change over time; client analysis, allowing us to see how the scale of mobile devices affected medium interactions; URL analysis, comparing both to Archive

MATERIAL Y MÉTODOS: El estudio se realizó de diciembre de 2004 al mes de abril de 2005. El Pb en sangre se midió por voltamperometría de redisolución anódica, mientras que se utilizó energía dispersa de fluorescencia por rayos X para las otras matrices. RESULTADOS: Con base en los criterios de la Norma Oficial Mexicana (NOM se encontró que 90% de los menores está en la categoría I, 5% se encuentra en la categoría II y el otro 5% se ubica en la categoría III. El suelo de los terrenos aledaños a la recicladora tiene en promedio 4 940 µg/g, en un intervalo de 73 a 84 238 µg/g. Las mayores concentraciones se localizan en los puntos más cercanos a la empresa. El suelo de San Ignacio tiene en promedio 109 µg/g. Se encontraron valores altos en el barro vidriado y la concentración del Pb en las plantas es superior a los 300 µg/g. CONCLUSIONES: A pesar de que la mayoría de los niños analizados presenta niveles de plomo en sangre que la Norma Mexicana señala como aceptables, varios estudios indican que existen efectos nocivos aun a concentraciones bajas. Los terrenos aledaños a la empresa están contaminados, y en esa medida los alimentos que ahí se producen, al ser consumidos, son una fuente de contaminación, que se agudiza con el uso de barro vidriado.OBJECTIVE:To determine the lead concentration in the blood of children and nursing or pregnant women from San Ignacio, Fresnillo, in Zacatecas, Mexico as well as in soil, plants, ash and lead-glazed pottery, in order to determine exposure due to a metal-recycling facility.

  15. Is there any rationale to the Brazilian fiscal policy?

    Full Text Available Barro's tax smoothing hypothesis (TSH implies that, when faced by a temporary increase in expenditure, the government should issue debt in order to spread the increase in taxes over time and minimize the welfare costs of high tax rates. Changes in the tax rate should then be unpredictable. This paper performs a test of the TSH that goes beyond the random walk tests usually done in literature. It examines the implied restrictions of the TSH on a vector autoregression (VAR model using Brazilian data for the period 1970-94. The tests reject the hypothesis for the full sample period. For the period 1987-92, however, disregarding the volatility of the actual budget surplus, the TSH seems to provide a better approximation to the historical movements of Brazilian fiscal data series.A hipótese de suavizamento de impostos de Barro implica, que quando o Governo se defronta com um aumento temporário nos seus gastos, ele deve emitir dívida a fim de espalhar o aumento de impostos ao longo do tempo e minimizar os custos de bem estar associados com os impostos mais altos. Neste artigo, faz-se um teste da hipótese de suavizamento de impostos que vai além dos tradicionais testes de passeio aleatório feitos na literatura. Examina-se as restrições sobre os gastos, as receitas e os déficits brasileiros trazidas pela hipótese de suavizamento, usando-se um modelo de vetores autoregressivos para 1970-94. Os testes rejeitam a hipótese quando o período amostral completo é considerado. Contudo, para o período 1987-92, desconsiderando-se a volatilidade dos saldos orçamentários efetivos, a hipótese de suavizamento de impostos parece fornecer uma aproximação melhor para os movimentos históricos das séries fiscais brasileiras.

  16. Predicting spatial variations of tree species richness in tropical forests from high-resolution remote sensing.

    2015-10-01

    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

A mais importante sucessão sedimentar portadora de carvão no Brasil ocorre na Bacia do Paraná, com as maiores reservas localizadas nas jazidas do RS e de SC. Este trabalho tem por objetivo analisar as características químicas e petrográficas das camadas de carvão de três poços, realizados recentemente na jazida Sul Catarinense (SC nos municípios de Treviso e Araranguá, com o intuito de avaliar a capacidade de geração de gás metano associado. Foram coletadas amostras de sete camadas de carvão (Barro Branco, Irapuá, A, Bonito Superior, Bonito Inferior, Pré-Bonito Superior e Pré-Bonito Inferior da Formação Rio Bonito que foram submetidas à análise petrográfica e química. O litotipo carvão fosco bandado (BD predominou no CBM-SC-2012, e carvão fosco (D, no CBM-SC-2013. Os resultados petrográficos indicaram valores de 0,60 a 1,26 Rrandom (%, classificando o carvão segundo o rank desde betuminoso alto volátil C até betuminoso médio volátil. A análise de macerais mostra variação na composição das camadas, com predomínio de vitrinita e inertinita. Quanto à análise imediata, as amostras variaram de 34,93 a 65,70% em peso de cinza. O poder calorífico varia de 1858,0 a 5074,8 cal/g. O conteúdo de carbono varia de 4,15 a 65,81%, e o enxofre, de 0,22 a 12,43%. De acordo com os parâmetros analisados, as camadas Barro Branco e Irapuá apresentam as condições necessárias para geração e armazenagem de gás natural, enquanto a camada Bonito apresenta baixo potencial devido ao alto conteúdo de matéria mineral.

    Full Text Available A morte fetal não é uma entidade rara e, em países em desenvolvimento, suas causas mais prevalentes continuam sendo passíveis de controle e/ou tratamento. O objetivo deste estudo foi investigar causas de morte fetal em uma população brasileira. Foi um estudo descritivo realizado no Hospital Maternidade Leonor Mendes de Barros, em São Paulo. Foram estudadas 122 gestantes com diagnóstico de óbito fetal e idade gestacional de vinte semanas ou mais. Os procedimentos estatísticos utilizados foram média e desvio-padrão. As principais causas de morte identificadas foram hipertensão arterial e infecções e em um quarto dos casos a causa não foi determinada. Concluiu-se que uma proporção importante de óbitos era prevenível e que houve taxa significativa de causas não-identificadas. Os resultados deste estudo poderão ser úteis para orientação de programas de prevenção primária, principalmente quanto à assistência pré-natal.Fetal death may not be considered an unusual event and, in developing countries, the most prevalent causes could be possibly controlled and/or treated. The purpose of the present study was to investigate causes of fetal death in a Brazilian population. This is a descriptive study performed at the Hospital Maternidade Leonor Mendes de Barros in São Paulo. The study subjects were 122 pregnant women with diagnosis of fetal death and gestation age of 20 or more weeks. The statistical procedures used were means and standard deviation. The main causes of the fetal death were hypertensive disorders and infections and, for a quarter of the cases, they were not identified at all. It is concluded that an important percentage of fetal deaths would have been prevented and that there was a significant number of unidentified causes. Results of the present study might be useful to orientate a primary prevention health program, specially concerning antenatal care.

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.

    Full Text Available An experimental circuit of copper electrorefining using three types of anodes coming from three different Chilean foundries: Hernán Videla Lira, Las Ventanas and El Teniente was used to simulate the electrorefining process. In this circuit the problem of the cathode rejection and the influence of some process variables in this phenomenon were studied. The variables analyzed were: electrolyte cell flow, solids in suspension, current density, lead doping in the anodes and density and particle size of the anodic slimes generated. The main results obtained from the experimental circuit were the following: the electrolyte flow doesn’t affect significantly the cathodic rejection, an increase of current density produces a decrease of cathodic rejections, the presence of the solids in suspension causes cathodes outside of norm, and to bigger quantity of lead in the anodes smallest were the rejections.

    Se trabajó en un circuito experimental de electrorrefinación de cobre, utilizando tres tipos de ánodos procedentes de tres fundiciones chilenas diferentes: Hernán Videla Lira, Las Ventanas y El Teniente. En este circuito, se estudió el problema del rechazo de cátodos y la influencia de algunas variables de proceso en este fenómeno. Las variables analizadas fueron: flujo de electrolito en la celda, sólidos en suspensión, densidad de corriente, dopado de plomo en los ánodos, densidad de los barros anódicos generados y tamaño de partícula de los barros anódicos. Los principales resultados obtenidos a partir del estudio del circuito experimental fueron los siguientes: el flujo de electrolito no afecta significativamente el rechazo de cátodos, a medida que aumenta la densidad de corriente disminuyen los rechazos, el aumento de los sólidos en suspensión provoca cátodos fuera de norma y a mayor cantidad de plomo en los ánodos menores fueron los rechazos.

  1. Is hepatic lipid metabolism of beef cattle influenced by breed and dietary silage level?

    Science.gov (United States)

    2014-01-01

    Background In ruminants, unsaturated dietary fatty acids are biohydrogenated in the rumen and are further metabolised in various tissues, including liver, which has an important role in lipid and lipoprotein metabolism. Therefore, manipulation of muscle fatty acid composition should take into account liver metabolism. In the present study, the influence of breed and diet on liver lipid composition and gene expression was investigated in order to clarify the role of this organ in the lipid metabolism of ruminants. Forty purebred young bulls from two phylogenetically distant autochthonous cattle breeds, Alentejana and Barrosã, were assigned to two different diets (low vs. high silage) and slaughtered at 18 months of age. Liver fatty acid composition, mRNA levels of enzymes and transcription factors involved in lipid metabolism, as well as the plasma lipid profile, were assessed. Results In spite of similar plasma non-esterified fatty acids levels, liver triacylglycerols content was higher in Barrosã than in Alentejana bulls. Moreover, the fatty acid composition of liver was clearly distinct from the remaining tissues involved in fatty acid metabolism of ruminants, as shown by Principal Components Analysis. The hepatic tissue is particularly rich in α-linolenic acid and their products of desaturation and elongation. Results indicate that DGAT1, ELOVL2, FADS1 and FADS2 genes influence the fatty acid composition of the liver the most. Moreover, genes such as DGAT1 and ELOVL2 appear to be more sensitive to genetic background than to dietary manipulation, whereas genes encoding for desaturases, such as FADS1, appear to be modulated by dietary silage level. Conclusions Our results indicate that liver plays an important role in the biosynthesis of n-3 LC-PUFA. It is also suggested that dietary silage level influences the hepatic fatty acid metabolism in a breed-dependent manner, through changes in the expression of genes encoding for enzymes associated with the

    We have recently discovered five Lyman continuum leaking galaxies at z~0.3, selected for their compactness, intense star-formation, and high [OIII]/[OII] ratio (Izotov et al. 2016ab). Here we derive their ionizing photon production efficiency, a fundamental quantity for inferring the number of photons available to reionize the Universe, for the first time for galaxies with confirmed strong Lyman continuum escape (fesc~6-13%). We find an ionizing photon production per unit UV luminosity, which is a factor 2-6 times higher than the canonical value when reported to their observed UV luminosity. After correction for extinction this value is close to the canonical value. The properties of our five Lyman continuum leakers are found to be very similar to those of the confirmed z=3.218 leaker Ion2 from de Barros et al. (2016) and very similar to those of typical star-forming galaxies at z>~6. Our results suggest that UV bright galaxies at high-z such as Lyman break galaxies can be Lyman continuum leakers and that the...

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.

    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.

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.

    The form of animal social systems depends on the nature of agonistic and affiliative interactions. Social network theory provides tools for characterizing social structure that go beyond simple dyadic interactions and consider the group as a whole. We show three groups of capuchin monkeys from Barro Colorado Island, Panama, where there are strong connections between key aspects of aggression, grooming, and proximity networks, and, at least among females, those who incur risk to defend their group have particular "social personalities." Although there is no significant correlation for any of the network measures between giving and receiving aggression, suggesting that dominance relationships do not follow a simple hierarchy, strong correlations emerge for many measures between the aggression and grooming networks. At the local, but not global, scale, receiving aggression and giving grooming are strongly linked in all groups. Proximity shows no correlation with aggression at either the local or the global scale, suggesting that individuals neither seek out nor avoid aggressors. Yet, grooming has a global but not local connection to proximity. Extensive groomers who tend to direct their efforts at other extensive groomers also spend time in close proximity to many other individuals. These results indicate the important role that prosociality plays in shaping female social relationships. We also show that females who receive the least aggression, and thus pay low costs for group living, are most likely to participate in group defense. No consistent "social personality" traits characterize the males who invest in group defense.

    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.

    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.

    Dioecy has a demographic disadvantage compared with hermaphroditism: only about half of reproductive adults produce seeds. Dioecious species must therefore have fitness advantages to compensate for this cost through increased survival, growth, and/or reproduction. We used a full life cycle approach to quantify the demographic costs and benefits associated with dioecy while controlling for demographic differences between dioecious and hermaphroditic species related to other functional traits. The advantage of this novel approach is that we can focus on the effect of breeding system across a diverse tree community. We built a composite integral projection model for hermaphroditic and dioecious tree populations from Barro Colorado Island, Panama, using long-term demographic and newly collected reproductive data. Integration of all costs and benefits showed that compensation was realized through increased seed production, resulting in no net costs of dioecy. Compensation was also facilitated by the low contribution of reproduction to population growth. Estimated positive effects of dioecy on tree growth and survival were small and insignificant for population growth rates. Our model revealed that, for long-lived organisms, the cost of having males is smaller than generally expected. Hence, little compensation is required for dioecious species to maintain population growth rates similar to those of hermaphroditic species.

  15. The cost of defeat: Capuchin groups travel further, faster and later after losing conflicts with neighbors.

    Although competition between social groups is central to hypotheses about the evolution of human social organization, competitive interactions among group-mates are thought to play a more dominant role in shaping the behavior and ecology of other primate species. However, few studies have directly tested the impact of intergroup conflicts in non-human primates. What is the cost of defeat? To address this question, the movements of six neighboring white-faced capuchin (Cebus capucinus) social groups living on Barro Colorado Island, Panama were tracked simultaneously using an Automated Radio Telemetry System (ARTS), for a period of six months. Groups moved 13% (441 m) further on days they lost interactions compared with days they won interactions. To cover these larger distances, they traveled faster, stopped less frequently, and remained active later in the evening. Defeat also caused groups to alter their patterns of space use. Losing groups had straighter travel paths than winning groups, larger net displacements and were more likely to change their sleeping site. These results demonstrate that losing groups pay increased travel costs and suggest that they forage in low-quality areas. They provide some of the first direct evidence that intergroup conflicts have important energetic consequences for members of competitively unsuccessful primate social groups. A better understanding of how intergroup competition impacts patterns of individual fitness is thus needed to clarify the role that this group-level process plays in shaping the evolution of human- and non-human primate behavior.

    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.

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.

    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.

  2. A UNIFORM FIRST-ORDER METHOD FOR THE DISCRETE ORDINATE TRANSPORT EQUATION WITH INTERFACES IN X,Y-GEOMETRY

    A uniformly first-order convergent numerical method for the discrete-ordinate transport equation in the rectangle geometry is proposed in this paper. Firstly we approximate the scattering coefficients and source terms by piecewise constants determined by their cell averages. Then for each cell, following the work of De Barros and Larsen[1, 19], the solution at the cell edge is approximated by its average along the edge. As a result, the solution of the system of equations for the cell edge averages in each cell can be obtained analytically. Finally, we piece together the numerical solution with the neighboring cells using the interface conditions. When there is no interface or boundary layer, this method is asymptotic-preserving, which implies that coarse meshes (meshes that do not resolve the mean free path) can be used to obtain good numerical approximations. Moreover, the uniform first-order convergence with respect to the mean free path is shown numerically and the rigorous proof is provided.

    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.

    An animal's ability to find and relocate food items is directly related to its survival and reproductive success. This study evaluates how mantled howler monkeys make spatial foraging decisions in the wild. Specifically, discrete choice models and agent-based simulations are used to test whether mantled howler monkeys on Barro Colorado Island, Panama, integrate spatial information in order to maximize new leaf flush and fruit gain while minimizing distance traveled. Several heuristic models of decision making are also tested as possible alternative strategies (movement to core home range areas instead of individual trees, travel along a sensory gradient, movement along arboreal pathway networks without a predetermined destination, straight-line travel in a randomly chosen direction, and random walks). Results indicate that although leaves are the single most abundant item in the mantled howler monkey diet, long-distance travel bouts target the areas with the highest concentrations of mature fruits. Observed travel patterns yielded larger estimated quantities of fruit in shorter distances traveled than all alternative foraging strategies. Thus, this study both provides novel information regarding how primates select travel paths and suggests that a highly folivorous primate integrates knowledge of spatiotemporal resource distributions in highly efficient foraging strategies.

    In the lowland moist forest of Barro Colorado Island (BCI), Panama, larvae of four common species of odonates, a mosquito, and a tadpole are the major predators in water-filled tree holes. Mosquito larvae are their most common prey. Holes colonized naturally by predators and prey had lower densities of mosquitoes if odonates were present than if they were absent. Using artificial tree holes placed in the field, we tested the effects of odonates on their mosquito prey while controlling for the quantity and species of predator, hole volume, and nutrient input. In large and small holes with low nutrient input, odonates depressed the number of mosquitoes present and the number that survived to pupation. Increasing nutrient input (and consequently, mosquito abundance) to abnormally high levels dampened the effect of predation when odonates were relatively small. However, the predators grew faster with higher nutrients, and large larvae in all three genera reduced the number of mosquitoes surviving to pupation, even though the abundance of mosquito larvae remained high. Size-selective predation by the odonates is a likely explanation for this result; large mosquito larvae were less abundant in the predator treatment than in the controls. Because species assemblages were similar between natural and artificial tree holes, our results suggest that odonates are keystone species in tree holes on BCI, where they are the most common large predators.

    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.

    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.

[102, 103]) most of the properties of fractional pro­ grams could be found in other programs, given that the objective function could be written as a particular composition of functions. 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. [9]) developed a cutting plane algorithm capable of optimizing C-programs. 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 ...

    Full Text Available Este artículo tiene como propósito hacer una estimación econométrica del modelo de gasto público y crecimiento económico de Barro (1990. La estimación se realizó mediante el método generalizado de los momentos (GMM para la economía colombiana durante el período 1950-2010. Los resultados obtenidos sugieren que el tamaño óptimo del gasto público se sobrepasó al empezar la década de los noventa. Además, se encontró que el tamaño del gasto público que maximiza la tasa de crecimiento del PIB per cápita depende inversamente del grado relativo de aversión al riesgo y que la elasticidad de sustitución intertemporal es baja para el período analizado

Estas pruebas resuelven el problema de las distorsiones por el uso de muestras pequeñas, propias de las series de tiempo. Las pruebas de raíces unitarias muestran que no hay evidencia de convergencia absoluta de 1970 a 2004 y para otros dos subperiodos. Sin embargo, las pruebas de cointegración arrojan evidencia en favor de la convergencia condicional para el mismo periodo. Las estimaciones de la velocidad de convergencia (Mark y Sul, 2003 indican que las regiones más ricas convergen más rápidamente que las pobres.

    Full Text Available The disposal of solid waste can create environmental problems, in addition to the potential risk of instability even in planned geotechnical works, such as provisions in stacks or high ends of the landfill, because they represent mere adjustments in civil engineering works. The Leme city, SP, generates about 35 t/day of municipal waste, that are deposited in a landfill located in the Barro Preto neighborhood. This work conducted a geophysical survey, based on geotechnical instability evidence in area, for analysis of the conditioners that cause on the sides leachate resurgence landfill and its relationship to mass movements and ravines installation in cover soil, with consequent waste exposure. The results indicate horizons of low resistivity connected with resurgence points generated by the organic matter decomposition contained in the waste. Such horizons result in leachate concentration in some places, which, in turn, may lead to loss of cohesion of the materials constituting the residues mass. The results are areas with mass flow by rotational movements, which, together with the surface flow of rainwater, evolves into ravines and exposed residues, preferably at the resurgence point. The leachate flow on the surface affects areas beyond the limits at landfill with direct impact on local agriculture and risk to pedestrians using the highway bordered by the landfill beyond the soil and the local aquifer.

    Established immobilization protocols are required for safe procedures on wildlife and zoo animals. This study evaluated the cardiovascular, respiratory, and anesthetic effects of dexmedetomidine (40 μg/kg) with S-ketamine (5 mg/kg) and midazolam (0.5 mg/kg) with S-ketamine (5 mg/kg) in 12 specimens of oncilla (Leopardus tigrinus) at Quinzinho de Barros Municipal Zoo Park in Sorocaba, São Paulo, Brazil, between January and March 2010. Each animal underwent both protocols, totaling 24 anesthetic procedures. The dexmedetomidine-S-ketamine group (DK) showed a decrease in heart rate compared to initial values and significantly lower heart rate and oxyhemoglobin saturation values compared to Midazolam-S-Ketamine Group (MK). Four animals in DK had episodes of sinus pauses. Systemic blood pressure, respiratory frequency, and rectal temperature showed no significant differences between groups. The dexmedetomidine-S-ketamine group showed a greater degree of muscle relaxation and allowed for more thorough and longer oral evaluations. The dexmedetomidine-S-ketamine group had a shorter period of recumbency, longer period to return of muscle tone, and shorter recovery time. Two animals in MK did not reach recumbency. The dexmedetomidine-S-ketamine group had better qualities of induction and recovery. It may be concluded that both protocols can be safely used in oncillas. Midazolam-S-ketamine promotes effective chemical restraint for quick and minimally invasive procedures and dexmedetomidine-S-ketamine promotes effective chemical restraint for prolonged and more invasive procedures.

    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.

    Currently only 32 species of limno-terrestrial tardigrades have been reported in the literature for Colombia. Our study focused on both heterotardigrades and eutardigrades, which were extracted from eight samples of bryophytes and lichens collected in a sub-Andean forest transect in the Sierra Nevada de Santa Marta, Colombia. Fourteen species were found, six of which are new records for Colombia: Echiniscus madonnae Michalczyk & Kaczmarek, 2006, Echiniscus virginicus Riggin, 1962, Milnesium krzysztofi Kaczmarek & Michalczyk, 2007, Doryphoribius amazzonicus Lisi, 2011, Isohypsibius sattleri (Richters, 1902) and Diphascon higginsi Binda, 1971; and one new to science. Itaquascon pilatoi sp. nov., is characterized by having smooth cuticle, no eyes, buccal tube almost as long as the pharyngeal tube, well developed, obvious stylet furcae with long branches, slender claws, no lunules and no cuticular bars on the legs. The new species differs from I. umbellinae Barros, 1939, the most similar species, in having the stylet supports inserted precisely at the border between buccal and pharyngeal tube, more slender claws and more pronounced length differential between the external and internal claws of each leg. The total number of Colombian limno-terrestrial tardigrade species is raised to 37. 

  3. Culturing and direct PCR suggest prevalent host generalism among diverse fungal endophytes of tropical forest grasses.

    Most studies examining endophytic fungi associated with grasses (Poaceae) have focused on agronomically important species in managed ecosystems or on wild grasses in subtropical, temperate and boreal grasslands. However grasses first arose in tropical forests, where they remain a significant and diverse component of understory and forest-edge communities. To provide a broader context for understanding grass-endophyte associations we characterized fungal endophyte communities inhabiting foliage of 11 species of phylogenetically diverse C(3) grasses in the understory of a lowland tropical forest at Barro Colorado Island, Panama. Our sample included members of early-arising subfamilies of Poaceae that are endemic to forests, as well as more recently arising subfamilies that transitioned to open environments. Isolation on culture media and direct PCR and cloning revealed that these grasses harbor species-rich and phylogenetically diverse communities that lack the endophytic Clavicipitaceae known from diverse woodland and pasture grasses in the temperate zone. Both the incidence and diversity of endophytes was consistent among grass species regardless of subfamily, clade affiliation or ancestral habitat use. Genotype and phylogenetic analyses suggest that these endophytic fungi are predominantly host generalists, shared not only among distinctive lineages of Poaceae but also with non-grass plants at the same site.

    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.

    The Cana Brava Complex is the northernmost and least well known layered intrusion of a discontinuous belt of mafic-ultramafic massifs within the Brasilia Belt, which also comprises theNiquelândia and Barro Alto complexes. Available geochronological data from a range of techniques (K/Ar, Ar/Ar, Rb/Sr, Sm/Nd and U/Pb) provide a range of possible ages (time span from 3.9 Ga to 450 Ma), hence a precise and reliable age for the Cana Brava Complex is still lacking. Also, preliminary isotopic and geochemical data of the Cana Brava Complex suggest a significant crustal contamination, which could have affected bulk-rock Sr and Nd systematics resulting in meaningless age determinations. In this paper, we present new U-Pb SHRIMP zircon analyses from four samples of different units of the Cana Brava Complexwhich suggest that the intrusion occurred during the Neoproterozoic, between 800 and 780 Ma, i.e. at the same age ofNiquelândia. Discordant older 206Pb/238U ages are provided by inherited zircons, and match the age of the metamorphism of the embedding Palmeirópolis Sequence.

    2015-12-01

    Tropical species may be highly sensitive to temperature increases associated with climate change because of their narrow thermal tolerances. Recent work has highlighted the importance of temperature in tropical forest function, however most studies use air temperature measurements from sparse meteorological stations even though surface temperatures are known to deviate from air temperatures. Tropical organisms exist in microclimates that are highly variable in space and time and not easily measured in natural environments. This is in part because of the complex structure of tropical forests and the potential for organisms themselves to modify their own environment. In the case of plants, leaf temperature is linked to the water and surface energy balance of their microenvironment. Here we present results from near-continuous thermal camera monitoring of the forest canopy in Barro Colorado Island, Panama (5-minute intervals for approximately 9 months). We compare daytime (maximum) vs. nighttime (minimum) differences between canopy temperature and air temperature, relative humidity, solar radiation, and precipitation. On average, canopy temperatures are consistently ~2 degrees Celsius higher than air temperatures. These data can paired with flux tower data on-site and used to advance understanding of temperature controls on the structure and function of tropical forests, such as carbon assimilation, phenology, and habitat monitoring, and can be integrated into models to improve predictions of tropical forest response to future climate change.

    In the light of intriguing results of C.C.Barros, we investigate in this thesis the possibilities of geometrical interpretation of all the fundamental interactions in order to unify them. More exactly we try to supply a unified geometrical description for gravitation and electromagnetism. The analysis of Huei's standard approach of Linear Gravity, in which the Einstein equations can be written in the same form of the Maxwell ones, revealed the existence of some imperfections. In fact, the relation between the scalar potential and the electric-type field is not valid except in the harmonic gauge, the Lorentz-type force is obtained with a time independence restriction and an undesired factor 4 appears in the magnetic-type part. A subtle gauge conditions allows us to eliminate these imperfections and to revisit the Linear Gravity in a way to get a strong similarity with electromagnetism. In the linear case, we showed that Maxwell's equations could be derived from an electromagnetic version of the Einstein ones, ...

    Full Text Available 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.

Un hallazgo casual, un pozo que se hundió por casualidad, abrió la puerta para redescubrir el origen de la zona.

    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.

    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 $71.7\\pm6.3$ M${_\\oplus}$. 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${_\\oplus}$ and of K2-19c of $9.7^{+3.9}_{-2.0}$ M${_\\oplus}$. A prior K2-19b mass estimated by Barros 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 densit...

    The processes that govern diverse tropical plant communities have rarely been studied in life forms other than trees. Structurally dependent vascular epiphytes, a major part of tropical biodiversity, grow in a three-dimensional matrix defined by their hosts, but trees differ in their architecture, bark structure/chemistry and leaf phenology. We hypothesized that the resulting seasonal differences in microclimatic conditions in evergreen vs. deciduous trees would affect epiphytes at different levels, from organ physiology to community structure. We studied the influence of tree leaf phenology on vascular epiphytes on the Island of Barro Colorado, Panama. Five tree species were selected, which were deciduous, semi-deciduous or evergreen. The crowns of drought-deciduous trees, characterized by sunnier and drier microclimates, hosted fewer individuals and less diverse epiphyte assemblages. Differences were also observed at a functional level, e.g. epiphyte assemblages in deciduous trees had larger proportions of Crassulacean acid metabolism species and individuals. At the population level a drier microclimate was associated with lower individual growth and survival in a xerophytic fern. Some species also showed, as expected, lower specific leaf area and higher δ(13)C values when growing in deciduous trees compared with evergreen trees. As hypothesized, host tree leaf phenology influences vascular epiphytes at different levels. Our results suggest a cascading effect of tree composition and associated differences in tree phenology on the diversity and functioning of epiphyte communities in tropical lowland forests.

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 One of important subjects considered in models of economic growth is convergence hypothesis. It posits that if different regions have identical levels of log-term equilibrium per capita GDP, the poor regions would have higher rate of per capita GDP growth than rich ones. Therefore the more poor regions would converge towards richer regions in terms of economic conditions. However, since determining factors for long term per capita GDP is not the same in all of regions, the conditional convergence is suggested. This hypothesis states that farer regions from long term per capita GDP would have higher rate of per capita GDP. Since determining factors on economic growth can influence on convergence process, the impact of consuming petroleum products as a determining variable on economic growth has been studied. The model of Barro and Sala-I-Martin was applied in order to examine convergence and the impact of consuming petroleum products on convergence and also reduction of regional inequality among Iran's provinces from 2000 through 2011. Results indicated that there is an unconditional convergence among Iran's provinces and also variables of gasoline, diesel, and Mazut (fuel oil have significant impact on economic growth and lead to negative convergence among Iran's province. Hence, respecting these results it can be concluded that using energy subsides cannot reduce regional inequality.

    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)

    The Atesina Volcanic District, the Monte Luco volcanics, and the Cima d'Asta, Bressanone-Chiusa, Ivigna, Monte Croce and Monte Sabion intrusions, in the central-eastern Southern Alps, form a wide calc-alkaline association of Permian age (ca. 280-260 Ma). The magmatism originated during a period of post-orogenic extensional/transtensional faulting which controlled the magma ascent and emplacement. The magmatic products are represented by a continuum spectrum of rock types ranging from basaltic andesites to rhyolites, and from gabbros to monzogranites, with preponderance of the acidic terms. They constitute a metaluminous to weakly peraluminous series showing mineralogical, petrographic and chemical characteristics distinctive of the high-K calc-alkaline suites. In the MORB-normalized trace element diagrams, the most primitive volcanic and plutonic rocks (basaltic andesites and gabbros with Mg No.=66 to 70; Ni=25 to 83 ppm; Cr=248 to 679 ppm) show LILE and LREE enriched patterns with troughs at Nb-Ta and Ti, a distinctive feature of subduction-related magmas. Field, petrographic, geochemical and isotopic evidence (initial 87Sr/ 86Sr ratios from 0.7057 to 0.7114; ɛNd values from -2.7 to -7.4; ∂ 18O values between 7.6 and 9.5‰) support a hybrid nature for both volcanic and plutonic rocks, originating through complex interactions between mantle-derived magmas and crustal materials. Only the scanty andalusite-cordierite and orthopyroxene-cordierite bearing peraluminous granites in the Cima d'Asta and Bressanone-Chiusa intrusive complexes can be interpreted as purely crustal melts (initial 87Sr/ 86Sr=0.7143-0.7167; initial ɛNd values between -7.9 and -9.6, close to average composition of the granulitic metasedimentary crust from the Ivrea Zone in the western Southern Alps). Although the Permian magmatism shows geochemical characteristics similar to those of arc-related suites, palaeogeographic restorations, and geological and tectonic evidence, seem not to support

    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.

    Full Text Available Decisions and practical attitudes of land use and management adopted by rural populations are, to a great extent, based on local soil knowledge. 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.

    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.

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.

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. From this collection, we have chosen those pieces of most interest, such as the idols. They have been divided into different types so there is a great variety among them: stone baetyls, idol-plaques, phalanges with decoration, eye-flat idols

    The main kidney transporter of many commonly prescribed drugs (e.g. penicillins, diuretics, antivirals, methotrexate, and non-steroidal anti-inflammatory drugs) is organic anion transporter-1 (OAT1), originally identified as NKT (Lopez-Nieto, C. E., You, G., Bush, K. T., Barros, E. J., Beier, D. R., and Nigam, S. K. (1997) J. Biol. Chem. 272, 6471-6478). Targeted metabolomics in knockouts have shown that OAT1 mediates the secretion or reabsorption of many important metabolites, including intermediates in carbohydrate, fatty acid, and amino acid metabolism. This observation raises the possibility that OAT1 helps regulate broader metabolic activities. We therefore examined the potential roles of OAT1 in metabolic pathways using Recon 1, a functionally tested genome-scale reconstruction of human metabolism. A computational approach was used to analyze in vivo metabolomic as well as transcriptomic data from wild-type and OAT1 knock-out animals, resulting in the implication of several metabolic pathways, including the citric acid cycle, polyamine, and fatty acid metabolism. Validation by in vitro and ex vivo analysis using Xenopus oocyte, cell culture, and kidney tissue assays demonstrated interactions between OAT1 and key intermediates in these metabolic pathways, including previously unknown substrates, such as polyamines (e.g. spermine and spermidine). A genome-scale metabolic network reconstruction generated some experimentally supported predictions for metabolic pathways linked to OAT1-related transport. The data support the possibility that the SLC22 and other families of transporters, known to be expressed in many tissues and primarily known for drug and toxin clearance, are integral to a number of endogenous pathways and may be involved in a larger remote sensing and signaling system (Ahn, S. Y., and Nigam, S. K. (2009) Mol. Pharmacol. 76, 481-490, and Wu, W., Dnyanmote, A. V., and Nigam, S. K. (2011) Mol. Pharmacol. 79, 795-805). Drugs may alter metabolism by

    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.

    Wolf, Jeffrey Arien

    Understanding the links between biodiversity and biogeochemistry in a spatial context within tropical forest plant communities is an unresolved problem. High plant diversity -- phylogenetic, functional, and genetic -- often characteristic of tropical forests, is poorly understood in the context of soils. I collected and georeferenced a large sample of surface soil cores (n=625, 6.25 cm diameter x 10 cm depth) from the Barro Colorado Island (BCI) 50 ha (0.5 km2) Forest Dynamics Plot (FDP), Republic of Panama (9.15 N, 79.8 W) -- described in Chapter One. In Chapter Two, I tested a commonly made assumption in research on plot scales in tropical forests, that abiotic controls entirely explain plot scale soil heterogeneity. To do this, I analyzed a high spatial resolution and multiple spatial scale (multiscale) set of topography features from airborne light detection and ranging (LiDAR), a bedrock map, and the geospatial soil chemical observations to test if abiotic controls (erosion, hydrology, bedrock) were sufficient to explain soil heterogeneity in the BCI tree community. In Chapter Three, I evaluate whether spatial variation in soil organic matter (SOM) and patterns of correlation with rock-derived nutrients are consistent with plants changing soils through litterfall. In Chapter Four, I document the first use of high-throughput DNA sequencing data for observing plant species roots in a tropical forest rhizosphere. The main findings of my dissertation are that at the plot scale in a tropical forest soil chemical heterogeneity was weakly related to abiotic controls and rock-derived macronutrients vary in association strength with soil organic matter in a manner consistent with plants exerting strong biotic controls on the spatial heterogeneity of soil calcium. Furthermore, that research is needed to understand plant nutrient cycling within the context of tropical forest plant communities.

    Studies of forest dynamics plots (FDPs) have revealed a variety of negative density-dependent (NDD) demographic interactions, especially among conspecific trees. These interactions can affect growth rate, recruitment and mortality, and they play a central role in the maintenance of species diversity in these complex ecosystems. Here we use an equal area annulus (EAA) point-pattern method to comprehensively analyze data from two tropical FDPs, Barro Colorado Island in Panama and Sinharaja in Sri Lanka. We show that these NDD interactions also influence the continued evolutionary diversification of even distantly related tree species in these FDPs. We examine the details of a wide range of these interactions between individual trees and the trees that surround them. All these interactions, and their cumulative effects, are strongest among conspecific focal and surrounding tree species in both FDPs. They diminish in magnitude with increasing phylogenetic distance between heterospecific focal and surrounding trees, but do not disappear or change the pattern of their dependence on size, density, frequency or physical distance even among the most distantly related trees. The phylogenetic persistence of all these effects provides evidence that interactions between tree species that share an ecosystem may continue to promote adaptive divergence even after the species' gene pools have become separated. Adaptive divergence among taxa would operate in stark contrast to an alternative possibility that has previously been suggested, that distantly related species with dispersal-limited distributions and confronted with unpredictable neighbors will tend to converge on common strategies of resource use. In addition, we have also uncovered a positive density-dependent effect: growth rates of large trees are boosted in the presence of a smaller basal area of surrounding trees. We also show that many of the NDD interactions switch sign rapidly as focal trees grow in size, and that

Nas primeiras obras destinadas ao público infantil, o infante era apenas receptor do texto e quase não aparecia como personagem, porém, com a consolidação do gênero, a criança alcança o lugar de protagonista. Neste texto, investiga-se o modo como duas obras contemporâneas se constroem (Os bolsos do mundo, de Fabiana Tasca, 2003 e Exercício de ser criança, de Manoel de Barros, 1999, a fim de analisar a proposta de leitura que subjaz às mesmas. Tais obras, pela palavra e ilustração, veiculam conteúdos que respeitam os anseios e as perspectivas da criança e expressam, respectivamente, a fantasia do público mirim, que concebe espaços do mundo como bolso que esconde seres, e a relação da menina com seu irmão apontando sonhos inerentes à infância. As duas narrativas, por meio da visualidade e da palavra, privilegiam a interação dos pequenos com o texto e sinalizam a emancipação do leitor e da própria literatura infantil, que assume estatuto de arte.

    In order to monitor biodiversity of rubber forest, a dynamic plot with an area of 1 hm2 of rubber forest was established by Rubber Research Institute of CATAS in Danzhou, Hainan in 2012. The construction technology and field protocol followed those applied in the establishment of the 50 hm2 plot in the tropical forest of Barro Colorado Island in Panama, developed by Smithsonian Tropical Research Institute in 1980. Due to its free, open source, powerful statistical analysis and perfect mapping function, R software was used by foreign scholars in the analyzing the complicated data of ecology. However, R software is not been well understand and used by most domestic scholars. In view of this, this article briefly introduced some application examples of R software in drawing contour map and three-dimensional map based on the field survey data of a 1 hm2 dynamic monitoring plot of rubber forest in Danzhou. And we hope this paper could help beginners for R software.%为开展橡胶林生物多样性动态监测,2012年由中国热带农业科学院橡胶研究所在海南儋州试验场四队橡胶林中建立了1 hm2动态监测样地.基于海南儋州1 hm2橡胶林动态监测样地的高程数据,介绍了R软件等高线图、三维立体图等方面的应用,希望对R软件的初学者有所帮助.

    Fruit-eating animals can influence the germination success of seeds through transportation and handling. We experimentally tested the contribution of ingestion by the common fruit-eating bat, Artibeus jamaicensis (Phyllostomidae, Chiroptera), to the percentage and rate of seed germination of figs (Ficus, Moraceae), which are considered keystone species for many frugivores. We collected fruits from three species of native free-standing figs (subgenus Pharmacosycea: F. insipida, F. maxima and F. yoponensis) and three species of native strangler figs (subgenus Urostigma: F. nymphiifolia, F. obtusifolia and F. popenoei) on Barro Colorado Island, Panama. The germination success of seeds removed from fruit pulp either manually or by ingestion was very high (>92%), while seeds that were not removed from fruit pulp were destroyed by fast-growing fungi within a few days. The dynamics of seed germination were not influenced by ingestion, but differed between the two subgenera of figs. In free-standing figs, germination started significantly earlier (5.3 +/- 0.7 days) than in strangler figs (8.6 +/- 1.4 days). Furthermore, strangler seeds were covered with a sticky coating and their seedlings developed cotyledons faster than fine roots, in contrast to free-standing figs that showed the opposite pattern. Our results demonstrate that the germination of fig seeds is positively influenced by passage through the gut of A. jamaicensis. Furthermore, free-standing and strangler figs revealed differences in germination parameters that might be adaptive with respect to the suitability of microsites such as tree fall gaps or host trees for establishment.

    Soils play a crucial role in biogeochemical cycles as spatially distributed sources and sinks of nutrients. Any spatial patterns depend on soil forming processes, our understanding of which is still limited, especially in regards to tropical rainforests. The objective of our study was to investigate the effects of landscape properties, with an emphasis on the geometry of the land surface, on the spatial heterogeneity of soil chemical properties, and to test the suitability of soil-landscape modeling as an appropriate technique to predict the spatial variability of exchangeable K and Mg in a humid tropical forest in Panama. We used a design-based, stratified sampling scheme to collect soil samples at 108 sites on Barro Colorado Island, Panama. Stratifying variables are lithology, vegetation and topography. Topographic variables were generated from high-resolution digital elevation models with a grid size of 5 m. We took samples from five depths down to 1 m, and analyzed for total and exchangeable K and Mg. We used simple explorative data analysis techniques to elucidate the importance of lithology for soil total and exchangeable K and Mg. Classification and Regression Trees (CART) were adopted to investigate importance of topography, lithology and vegetation for the spatial distribution of exchangeable K and Mg and with the intention to develop models that regionalize the point observations using digital terrain data as explanatory variables. Our results suggest that topography and vegetation do not control the spatial distribution of the selected soil chemical properties at a landscape scale and lithology is important to some degree. Exchangeable K is distributed equally across the study area indicating that other than landscape processes, e.g. biogeochemical processes, are responsible for its spatial distribution. Lithology contributes to the spatial variation of exchangeable Mg but controlling variables could not be detected. The spatial variation of soil total K

    F Andrew Jones

    Full Text Available BACKGROUND: 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. METHODOLOGY/PRINCIPAL FINDINGS: 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. CONCLUSIONS: 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.

    Full Text Available In this article we analysed the contribution made by the Livro de Duarte Barbosa (c. 1516 to the reception and interpretation of Indian culture and society by Europeans. The Livro remained unpublished in Portugal until the 19th century. However, from the onset, this narrative enjoyed a wide circulation both in Portugal and throughout Europe. Its manuscript form was known to the most distinguished chroniclers of Portuguese Asia, more precisely, Gaspar Correia, Lopes de Castanheda and João de Barros. Moreover, this report was translated into Castilian, German, and Italian still in the 16th century. For instance, an Italian translation was included in the first volume of the Navigazzioni e Viaggi (1550 by Giovanni Battista Ramusio that was one of the most important collectaneas on overseas travels dated from the second half of 16th century. Certainly, the Livro suffers from some limitations proper to his time such as religious prejudice, a discourse promoting an often civilizational identification that is not truthful among Europeans and non-Europeans, or the association of the skin complexion with a particular level of civility. Nevertheless, it constitutes one of the most comprehensive accounts of India written by Portuguese authors at the beginning of the 16th century. Indeed, this report includes fundamental information on the political, military, social, cultural, commercial and religious features characteristic of coeval India. As indicated by the title of the work, among the Indian regions that were described by Barbosa, pride of place was given to Malabar.This was related to the fact that he lived for almost fifty years in this region.

    Focal-mechanism determination of weak events recorded in sparse networks is challenging. First-motion polarities are often available at relatively distant stations, and waveforms only at a few near stations can be modeled. A two-step approach of how to combine such data has been suggested recently (Cyclic Scanning of the Polarity Solutions, or CSPS method; Fojtíková and Zahradník, 2014). It starts with creating a suite of first-motion polarity solutions, which is often highly non-unique. The next step consists of repeating full waveform inversion for all polarity solutions. Even few stations may efficiently reduce the non-uniqueness of the polarity solutions. Centroid depth, time, scalar moment and uncertainty estimate of the well-fitting double-couple solutions are obtained. The CSPS method has been extended in this paper by adding a new feature, i.e. repeated inversions using multiple first-motion polarity sets. The polarity sets are created by projecting the stations on focal sphere in several available velocity models, thus accounting for the takeoff angle uncertainty. The multiple polarity sets provide assessment of the CSPS solution stability. These ideas are demonstrated on a comprehensive analysis of a rare event in central Brazil. It is the Mw ˜4 mainshock of the Mara Rosa 2010 earthquake sequence (Barros et al., 2015, Carvalho et al., 2015). We employ polarities at 11 stations (distances Mara Rosa mainshock mechanism deviated from the composite solution of the whole sequence by 38°. The paper also includes a test simulating situations at which just a single waveform is used, and how it negatively affects the solution stability.

  13. 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.

En este artículo se evalúa si ha habido un cambio en la relevancia de esta variable bajo liberalización comercial. En particular, se evaluó la hipótesis de que liberalización comercial promovería el crecimiento de la productividad en las manufacturas de las ciudades del norte mexicano como resultado de los efectos dinámicos del comercio, dado que estas ciudades están más cercanas al nuevo mercado central para las manufacturas mexicanas y quizás a la pérdida de relevancia en los factores de crecimiento previamente acumulados (Livas y Krugman, 1992; Hanson, 1994. En contraste a esta hipótesis, se observa que las manufacturas en ciudades cercanas a los Estados Unidos no mostraron un mejor desempeño productivo que el resto de las manufacturas en el resto de las ciudades y que factores de crecimiento previamente acumulados, como educación e infraestructura, son aún relevantes para explicar el crecimiento de la productividad entre las manufacturas urbanas mexicanas.

    Full Text Available This article presents the first map in detail scale for an area covered by Palmas type volcanic rocks in the south border of the eocretaceous Paraná Magmatic Province, south Brazil. The study of the structural features coupled with petrography and geochemistry made it possible to separate these rocks into three main volcanic sequences and recognize their stratigraphy. The older Caxias do Sul sequence rests directly over the first low-Ti basalt flows (Gramado type, and corresponds to the stacking of lobated lava flows, laminar flows and lava domes, mostly emitted as continuous eruptions; only the latest eruptions are intercalated with thin sandstone deposits. These rocks have dacitic composition (~ 68 wt% SiO2 with microphenocrysts of plagioclase and subordinate pyroxenes and Ti-magnetite immersed in glassy or devitrified matrix. A second volcanic sequence, named Barros Cassal, is composed of several lava flows of basaltic andesite, andesitic and dacitic composition (~ 54; ~ 57 and ~ 63 wt% SiO2 , respectively, with microphenocrysts of plagioclase, pyroxenes and Ti-magnetite. The frequent intercalation of sandstone between the flows attests to the intermittent behaviour of this event. The upper sequence, Santa Maria, is made up of more silica-rich (~ 70 wt% SiO2 rocks occurring as laminar flows, lobated flows and lava-domes. These rocks have rhyolitic composition with microphenocrysts of plagioclase and Ti-magnetite set in a glassy or devitrified matrix with microlites. The structures and textures of all three silicic sequences favor the interpretation that they had a predominantly effusive character, which is thought to be a reflection of the remarkably high temperatures of the lavas (~ 1,000 ºC.

    Full Text Available How Much to Commit to an Exchange Rate Rule? Balancing Credibility and Flexibility There are different ways in which policy-makers back their commitment to a fixed exchange rate. A regime where countries can devalue unilaterally represents a weaker commitment than one where a devaluation needs to be agreed upon with other parties (e.g. the European monetary system. Full dollarization, understood here as full replacement of the domestic currency by the U.S. dollar, is an extreme commitment to a fixed exchange rate. Indeed, it is a especial case of a fixed exchange rate.The central message of this paper is that the cost of reneging is a key reason holding policymakers back from making strong commitments on their exchange rate policy. The stronger the commitment to an exchange rate rule, the more costly it is to deviate from it. The paper develops a Barro-Gordon type model in which the policymaker has to decide the degree of commitment under uncertainty.It is shown that, even for policy makers that have a strong preference for maintaining the fixed exchange rate, there are circunstances under which they will choose to devalue. This will happen when the economy is hit by an adverse shock and the costs of adhering to the fixed exchange rate are larger than those associated with devaluing.The model provides useful insights to understand why many high inflation economies have not adopted full dollarizarion as a way to stabilize prices. Our emphasis on the cost of reneging stands in contrast with most existing works, which single out the desire to rely on seigniorage as the main motive for stopping short of full dollarization. Strong commitments will only be made once there is a good chance that the policy maker will not renege, and by then they might not be necessary. We illustrate the main points of the paper with examples from Latin American countries.

Foi juntando extremidades opostas, a teoria musical e a pesquisa de um lado, a improvisação como pianista do outro, que a vontade de reunir reflexão e prática encontrou na composição a sua forma de expressão. Minha formação se deu inicialmente em um curso de inverno no Festival de Londrina com Hans J. Koellreutter em 1994. Em seguida, tive uma longa passagem pela universidade (bacharelado em composição na Unicamp, mestrado na mesma universidade. A pesquisa de doutorado sobre Luigi Nono (USP me ajudou a entrar em contato com a forma de abordagem intuitiva e baseada no som do compositor italiano, que também seria tão importante no meu trabalho. Sobre meus professores, numerosos diálogos me foram necessários - toda uma constelação de eventos para uma única págica de música bem-sucedida. Entre esses encontros, que tiveram um papel pedagógico fundamental - muito embora alguns deles tenham sido breves em forma de workshop ou conversa, estão as aulas de J. A. Mannis, Almeida Prado, Livio Tragtenberg, Fernando Iazzetta, Silvio Ferraz, Salvatore Sciarrino, Chaya Czernowin, Pierluigi Billone, Franck Bedrossian, Tristan Murail, Stefano Gervasoni, Michael Jarrell e Philippe Manoury. Minha experiência com o grupo de improvisação Abaetetuba, e em duo com Celio Barros e Florentin Ginot, constituiu meu grande laboratório prático, desenvolvendo escuta e resposta em forma de sons, que considero como uma importante etapa de gestação do meu projeto artístico.

    2015-12-01

    Fine scale tropical forest structure characterization has been performed by means of field measurements techniques that record both the specie and the diameter at the breast height (dbh) for every tree within a given area. Due to dense and complex vegetation, additional important ecological variables (e.g. the tree height and crown size) are usually not measured because they are hardly recognized from the ground. The poor knowledge on the 3D tropical forest structure has been a major limitation for the understanding of different ecological issues such as the spatial distribution of carbon stocks, regeneration and competition dynamics and light penetration gradient assessments. Airborne laser scanning (ALS) is an active remote sensing technique that provides georeferenced distance measurements between the aircraft and the surface. It provides an unstructured 3D point cloud that is a high-resolution model of the forest. This study presents the first approach for tropical forest characterization at a fine scale using remote sensing data. The multi-modal lidar point cloud is decomposed into 3D clusters that correspond to single trees by means of a technique called Adaptive Mean Shift Segmentation (AMS3D). The ability of the corresponding individual tree metrics (tree height, crown area and crown volume) for the estimation of above ground biomass (agb) over the 50 ha CTFS plot in Barro Colorado Island is here assessed. We conclude that our approach is able to map the agb spatial distribution with an error of nearly 12% (RMSE=28 Mg ha-1) compared with field-based estimates over 1ha plots.

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

    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.

    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 free-draining soils that dominate global forested areas. We examined trace gas (CH4 and N2O) fluxes from both soils and tree stems in a lowland tropical forest on free-draining soils in Panama, Central America and from a deciduous woodland in the United Kingdom. The tropical field site was a long-term experimental litter manipulation experiment in the Barro Colorado Nature Monument within the Panama Canal Zone, fluxes were sampled over the dry to wet season transition (March-August) in 2014 and November 2015. 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 (as per Siegenthaler et al. (2015)) and the soil fluxes were sampled from permanently installed collars inserted to a 3cm depth. We found that seasonality (precipitation) is a significant driver of changing soil exchange from methane uptake to emission at the Panama sites. Experimental changes to litter quantity only become significant when coupled with seasonal change. Seasonal variability is an important control of the fluxes at out temperate forest site with changes in temperature and soil water content leading to changes in soil and tree stem trace gas fluxes from Wytham Woods.

    The Center for Tropical Forest Research (CTFS), a program of the Smithsonian Tropical Research Institute (STRI), has coordinated a global network of 17 tropical forest dynamics plots of approximately 50 hectares in order to collect baseline information and to monitor forest changes. Missing from most past studies of these plots is an integrated soil hydrology and water chemistry component. To fill this gap, we have developed and are testing rapid assessment methods to measure soil and hydrological properties for tropical forest catchments. This assessment includes gaging and sampling first to third order headwater streams with high frequency over several storm events within a 2-4 week period. Detailed flow separations enable us to test Elsenbeer's (2001) functional classification continuum for tropical soils and allow us to test the hypothesis that forest sites with greater overland flow experience greater nutrient loss during storm events. Data from a storm event for the steep Lutz Creek Catchment on Barro Colorado Island, Panama in September 1990 demonstrate that Na+ and Si, typical of most solutes, decrease in concentration with increasing discharge. In contrast, the nutrients, K+ and NO3- increase in concentration with increasing discharge. Results from a 20 ha catchment in Yasuni National Park, Ecuador from November 2003 show a similar pattern during several small events on relatively impermeable soils. Data collected from a more permeable 20 ha catchment in Lambir Hills National Park, Malaysia in July 2004 also show nutrient export, but suggest that rainfall amount, intensity and duration may play a large role in the magnitude of nutrient concentrations.

    Two distinct Cambrian magmatic pulses are recognized in the Ossa-Morena Zone (SW Iberia): an early rift-(ER) and a main rift-related event. This Cambrian magmatism is related to intra-continental rifting of North Gondwana that is thought to have culminated in the opening of the Rheic Ocean in Lower Ordovician times. New data of whole-rock geochemistry (19 samples), Sm-Nd-Sr isotopes (4 samples) and ID-TIMS U-Pb zircon geochronology (1 sample) of the Early Cambrian ER plutonic rocks of the Ossa-Morena Zone are presented in this contribution. The ER granitoids (Barreiros, Barquete, Calera, Salvatierra de los Barros and Tablada granitoid Massifs) are mostly peraluminous granites. The Sm-Nd isotopic data show moderate negative ɛNdt values ranging from -3.5 to +0.1 and TDM ages greatly in excess of emplacement ages. Most ER granitoids are crustal melts. However, a subset of samples shows a transitional anorogenic alkaline tendency, together with more primitive isotopic signatures, documenting the participation of lower crust or mantle-derived sources and suggesting a local transient advanced stage of rifting. The Barreiros granitoid is intrusive into the Ediacaran basement of the Ossa-Morena Zone (Série Negra succession) and has yielded a crystallization age of 524.7 ± 0.8 Ma consistent with other ages of ER magmatic pulse. This age: (1) constrains the age of the metamorphism developed in the Ediacaran back-arc basins before the intrusion of granites and (2) defines the time of the transition from the Ediacaran convergent setting to the Lower Cambrian intra-continental rifting in North Gondwana.

    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

    The genus Caponina Simon, 1891 comprises eleven species of medium-sized, soil-dwelling caponiids. Most members of Caponina have six eyes, but some have five, four, three or two eyes (Brignoli 1977, Platnick 1994). The genus is widespread in South and Central America (Platnick 2012). To date, only three species have been recorded from Brazil: Caponina alegre Platnick, 1994 from the state of Rio Grande do Sul, C. notabilis (Mello-Leitão, 1939) from the states of Paraná and Rio Grande do Sul, and C. tijuca Platnick, 1994 from the state of Rio de Janeiro (Platnick 1994). In this paper we describe a new species from the state of Pará, in Brazilian Amazonia. Caponina papamanga new species was collected during the "Butantan na Amazonia" project, founded by the Instituto Butantan. The phylogenetic relationships of C. papamanga could not be studied, but the greatly elongated embolus, the dorsal tubercle on the palpal femur (Figs. 7, 9) and the massive epigynal sclerotizations (Fig. 10) suggest that this species belongs to the monophyletic Andean group proposed by Platnick (1994: 7). All morphological observations and illustrations were made using a Leica MZ12 stereomicroscope with camera lucida. The epigynum was dissected and immersed in clove oil for visualization of internal structures following Levi (1965). Descriptions and measurements follow Platnick (1994). Measurements are given in millimeters. Scanning electron microscope (SEM) images were taken using a Jeol-JSM-5200 with attached SLR digital camera.

    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.

    Tree deaths open gaps in closed-canopy forests, which allow light to reach the forest floor and promote seed germination and seedling establishment. Gap dependence of regeneration is an important axis of life history variation among forest plant species, and many studies have evaluated how plant species differ in seedling and sapling performance in gaps. However, relatively little is known about how seed arrival in gaps compares with seed arrival in the understory, even though seed dispersal by wind and animals is expected to be altered in gaps. We documented seed arrival for the first seven years after gap formation in the moist tropical forests of Barro Colorado Island (BCI), Panama, and evaluated how the amount and functional composition of arriving seeds compared with understory sites. On average, in the first three years after gap formation, 72% fewer seeds arrived in gaps than in the understory (207 vs. 740 seeds x m(-2) x yr(-1)). The reduction in number of arriving seeds fell disproportionately on animal-dispersed species, which suffered an 86% reduction in total seed number, while wind-dispersed species experienced only a 47% reduction, and explosively dispersed species showed increased seed numbers arriving. The increase in explosively dispersed seeds consisted entirely of the seeds of several shrub species, a result consistent with greater in situ seed production by explosively dispersed shrubs that survived gap formation or recruited immediately thereafter. Lianas did relatively better in seed arrival into gaps than did trees, suffering less of a reduction in seed arrival compared with understory sites. This result could in large part be explained by the greater predominance of wind dispersal among lianas: there were no significant differences between lianas and trees when controlling for dispersal syndromes. Our results show that seed arrival in gaps is very different from seed arrival in the understory in both total seeds arriving and functional

    Full Text Available Nos últimos anos, as instalações destinadas à produção avícola no Brasil têm-se destacado pelo aumento da densidade de criação que visa a otimizar mão-de-obra, equipamentos, transporte, assistência técnica e, sobretudo, instalações. O objetivo deste trabalho foi realizar pesquisa sobre as principais características tipológicas dos aviários existentes na mesorregião do Agreste do Estado da Paraíba. Observou-se que os aviários são predominantemente concebidos em pequenas dimensões de largura e comprimento, com baixa densidade de alojamento. A grande maioria dos galpões está localizada na direção leste-oeste, com pequena distância entre os aviários, apresentando piso de concreto, cobertura em formato de duas águas, estrutura do telhado em madeira, telhas de barro, ausência de lanternim, pé-direito baixo, beirais pequenos e muretas altas, além de disporem de cobertura vegetal ou outros elementos adequados ao correto paisagismo circundante. Quanto aos equipamentos, observou-se que a principal fonte de aquecimento é de campânulas à lenha, além de bebedouros automáticos pendulares e comedouros manuais. Cerca de 50% dos galpões possuíam ventiladores, mas pequena percentagem desses estava associada a nebulizadores.In the recent years, the installations destined for poultry production in Brazil have been remarkable due to increased bird density which aim to optimize man power, equipment, transport, technical assistance and over all installations.

    The role of environmental drivers in regulating carbon exchanges, such as the combined effects of different meteorological and hydrological factors, are still poorly understood in many tropical forests. For example, Central American tropical forests are characterized by a distinct dry season with large atmospheric evaporative demand, driven by solar radiations and sustained winds. In contrast, during the wet seasons, cloudiness results in lower radiation inputs but higher diffuse fraction, and higher water availability. Our site, Barro Colorado Island, located in Gatun Lake, Central Panama, averages 2800 mm of annual precipitation, with a pronounced dry season in Jan-Apr. Forest age varies between 100 and >400 yr. In July 2012, an eddy covariance system was installed on a 41 m tower on the top plateau of the island. In the current year (2015) the island is experiencing the most severe El Niño driven drought on record (precipitation is measured since 1921). The eddy covariance measurements show that carbon and water fluxes are strongly influenced by hydrological conditions. Prolonged dry spells during the dry season limit both above ground fluxes (ET and GPP) and below ground processes (root and microbial activities). Light use efficiency is about 30% lower during the dry season and evapotranspiration can be as 40% below potential. These decreases in ecosystem functions are driven primarily by a combination of structural (reduction in leaf area) and physiological (stomata regulation) adaptation. Similarly, soil effluxes respond strongly to hydrological conditions. In the dry season, lower soil respiration rates are spaced out by rare rain events generating large pulses. In contrast, during the wet season, frequent rain events suppress soil CO2effluxes, because of reduced diffusivity and oxygen depletion. Diurnal variation of soil respiration also suggested a potential translocation of photosynthates from leaf to roots to increase nutrient uptake during the dry

(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.

    The laterite Ni ore smelting operations in Niquelândia and Barro Alto (Goiás State, Brazil) have produced large amounts of fine-grained smelting wastes, which have been stockpiled on dumps and in settling ponds. We investigated granulated slag dusts (n = 5) and fly ash samples (n = 4) with a special focus on their leaching behaviour in deionised water and on the in vitro bioaccessibility in a simulated gastric fluid, to assess the potential exposure risk for humans. Bulk chemical analyses indicated that both wastes contained significant amounts of contaminants: up to 2.6 wt% Ni, 7580 mg/kg Cr, and 508 mg/kg Co. In only one fly ash sample, after 24 h of leaching in deionised water, the concentrations of leached Ni exceeded the limit for hazardous waste according to EU legislation, whereas the other dusts were classified as inert wastes. Bioaccessible fractions (BAF) of the major contaminants (Ni, Co, and Cr) were quite low for the slag dusts and accounted for less than 2 % of total concentrations. In contrast, BAF values were significantly higher for fly ash materials, which reached 13 % for Ni and 19 % for Co. Daily intakes via oral exposure, calculated for an adult (70 kg, dust ingestion rate of 50 mg/day), exceeded neither the tolerable daily intake (TDI) nor the background exposure limits for all of the studied contaminants. Only if a higher ingestion rate is assumed (e.g. 100 mg dust per day for workers in the smelter), the TDI limit for Ni recently defined by European Food Safety Authority (196 µg/day) was exceeded (324 µg/day) for one fly ash sample. Our data indicate that there is only a limited risk to human health related to the ingestion of dust materials generated by laterite Ni ore smelting operations if appropriate safety measures are adopted at the waste disposal sites and within the smelter facility.

    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.

  4. Phylogenetic analysis of local-scale tree soil associations in a lowland moist tropical forest.

    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

    Observational data provide a powerful source of information for understanding the phenological response of tropical forests to a changing climate. Annual changes in mean temperature, precipitation, and solar irradiance, in part driven by ENSO cycles, provide a natural experiment. However, these time series are often relatively short (several years to several decades), the average climatic variability experienced in that timeframe is relatively small, and the corresponding response is therefore often very weak. As a result, standard statistical approaches may fail in detecting a biological response. We present an alternative ecoinformatic analysis that demonstrates the power of weak models in the discovery and interpretation of statistically significant signals in short, noisy, ecological time series. We developed a simple response prediction model that uses cross-validation to explore a landscape of models that correlate the phenological behavior of individual taxa (pollen production, flowering, fruiting) to seasonal and annual mean temperature, precipitation, and solar irradiance using multivariate linear regression. We use a sign slope sensitivity analysis of each linear model that tallies positive and negative slope counts of a taxon's phenological behavior to our environmental and null variables. We applied this analysis to pollen trap data collected from 1996 to 2006 from two lowland Panamanian forests, Barro Colorado Island and Parque National San Lorenzo. We also tested the performance of our predictive model using published data of annual flowering and fruiting from BCI to corroborate that our approach could reproduce previously published results on tropical phenology. Our results indicate that although the overall variation in temperature was 3.28 °C over the ten year period, pollen productivity at both sites was most consistently affected by changes in temperature. This result was replicated by the published BCI flower and fruit data, which also

In the present study, we evaluated these subjects after the end of the intervention and compared the rate of age-related cognitive decline of those living in an enriched community environment (NI group, n=15, 74.1±3.9 years old with those living in the impoverished environment of long-term care institutions (I group, n=20, 75.1±6.8 years old. Both groups participated fully in our stimulation program. Over 1 year, we conducted revaluations at five time points (2 months, 4 months, 6 months, 8 months, and 12 months after the completion of the intervention. Both elderly groups were evaluated with the mini-mental state examination and selected language tests. Progressive cognitive decline was observed in both groups over the period. Indeed, it took only 4–6 months after the end of the stimulation program for significant reductions in language test scores to become apparent. However, earlier reductions in test scores were mainly associated with I group, and linguistic prosody test scores were significantly

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.

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.

Su función y uso originales se desconocen, pero los artefactos sonoros que se han examinado directamente pueden producir sonidos extraordinarios que se asemejan a los de algunos animales y de fenómenos de la naturaleza como el viento. Los más sencillos morfológicamente se pueden tocar dentro de la boca. Por el tipo de mecanismo sonoro y las señales que generan funcionan como generadores de ruido bucales. Morfológicamente, muestran dos perforaciones cara a cara y una cámara resonadora y de caos entre ellos. En este documento se proporciona la información disponible sobre los generadores de ruido bucales antiguos y contemporáneos que se han encontrado. Se aplica un método de análisis de aerófonos antiguos, mismo que ya se ha complementado y aplicado en más de sesenta estudios originales, incluyendo una tesis. En general, se indican las principales características organológicas, acústicas y posibles usos de los generadores de ruido bucales que fueron identificados y analizados por el autor. El análisis comparativo de los sonidos complejos y variables en el tiempo se realiza con espectrogramas y se dan estimaciones de algunos parámetros acústicos básicos como presión sonora (en dB y potencia acústica radiada máxima (en Watts. Los generadores de ruido bucales mesoamericanos conocidos provienen de varias zonas como las del Golfo y del Occidente, pero los últimos identificados son de las zonas de San Lorenzo Tenochtitlán, Veracruz y de San Juan Raya, Puebla.

    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 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

    The mixed broadleaved-Korean pine {Pinus koraiensis) forest (MBKF) represents the climax vegetation type of the eastern mountainous area of Northeast China. It is divided into three categories according to community structure and species composition, including southern MBKF, typical MBKF, and northern MBKF. To monitor long-term dynamics of the typical MBKF, we established a 9-ha plot following the field protocol of the 50 ha plot in Panama (Barro Colorado Island, BCI) in 2005 in Liangshui National Nature Reserve of Heilongjiang Province. All free-standing plant species with DBH (diameter at breast height) =1 cm were mapped, tagged, and identified to species in the plot. In the 2010 census, we documented 48 woody species with 21,355 individuals, belonging to 34 genera and 20 families. Most of the species belong to the Changbai Mountain plant flora, with a minor subtropical plant species component. The DBH distribution of all individuals showed a reversed "J" type, indicating well regenerated for the community. The DBH distribution for the canopy, sub-canopy, and middle layers and the understory layer showed the reversed "J" and "L" distributions, respectively. The DBH pattern of the nine dominant species can be classified into three categories: approximate normal, reversed "J", and "L" distribution. Spatial pattern analysis showed that the major tree species were aggregated, and aggregation intensity decreased as DBH increased. Further analysis showed that spatial distribution was closely related to topography and varied with DBH classes. For example, the distribution of Pinus koraiensis and Tilia amurensis was significantly affected by topography (P < 0.05); however, the distribution of Abies nephrolepis, Acer ukurunduense, and Ulmus laciniata correlated significantly with topography at diameter classes of I (DBH < 10 cm) and II (10 cm < DBH < 30 cm). The distribution of Betula costata and Acer tegmentosum was also significantly correlated with topography at a

    Community structure is one of the key features in the process of vegetation succession.Warm temperate mixed deciduous broad-leaved secondary forest is the main forest vegetation type in China's warm temperate zone.In order to better study the mechanisms of succession and species coexistence in this forest type, we established the Donglingshan 20-ha forest plot (DLS plot) in 2009 and 2010 using the same protocol as the well-established plot on Barro Colorado Island in Panama.In the plot, all free-standing woody plants with DBH (diameter at breast height) ≥1 cm were mapped, tagged, and identified to species.Here, we address preliminary results on floristic characteristics, community composition, and size-class, vertical, and spatial structure of the DLS plot.These datasets will serve as baseline information accessible to a wide range of future studies.We tagged a total of 52,136 genotype individuals (103,284 individuals including branches of genotype individuals), belonging to 58 species, 33 genera and 18 families.All of these tree species were deciduous.Floristic characteristics of the community suggested a temperate flora, including some subtropical and tropical elements.There were very obvious dominant species in the plot.Five species comprised 61% of all individuals, and 20 species comprised 92% of all individuals, while the other 38 species comprised only 8% of all individuals.Vertical structure was composed of an overstory layer (19 species), midstory layer (18 species), and a shrub layer (21 species).The DBH size-class structure of all species in the plot generally fitted a "reverse J" distribution, indicating good regeneration across the community.The size-class structure of the main species in the overstory layer showed a bimodal or nearly normal distribution, while the most abundant species in the midstory and shrub layers showed "reverse J" or even "L" distributions.Spatial distribution patterns of the dominant species varied with size-class and

    sea preciso reemplazar las recomendaciones existentes para la construcción con este material, producto casi exclusivo de la experiencia de algunos constructores que en el pasado han tenido éxito al trabajar con él, por una norma, que no sólo límite, sino que más que eso, establezca pautas que permitan construir en adobe con la seguridad necesaria, aprovechando las cualidades inherentes del mismo, el empleo de aditivos y naturalmente proponga pautas para el diseño y cálculo de sus estructuras con un respaldo empírico adecuado. 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. Para que el barro una vez seco, alcance características mecánicas satisfactorias y uniformes, es preciso que: i Se proceda al macerado del suelo en estado saturado de 48 a 72 horas. i i Antes del llenado de los moldes, proceder a un intenso amasado de la pasta, para así evitar que las láminas de arcilla se ordenen según atracciones eléctricas.

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.

    (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

    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

    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.

The energy spectra predicted by WRF-ARW are qualitatively compared with LES results to emphasize the limitations of the currently used turbulence parameterizations. Ongoing validation efforts include: (1) extending the interaction of large scale circulation with wall simulations to finer grids to capture a wider range of wavenumbers; and (2) a coupled 2D-3D simulation is planned to predict the entire atmospheric turbulence spectra at a very low computational expense. The overarching objective of this study to develop turbulence modeling capability based on the energy transfer mechanisms proposed in this study. Such a model will be implemented in WRF-ARW, and applied to atmospheric simulations, for example the prediction of moisture convergence patterns at the meso-scale in the southeast United States (Tao & Barros, 2008).

Bermingham - STRI. The magnitude-9 Sumatra-Andaman Islands earthquake of December 26, 2004, increased global awareness of the destructive hazard posed by earthquakes and tsunamis. In response to this tragedy, the US government undertook a collaborative project to improve earthquake and tsunami monitoring along a major portion of vulnerable coastal regions, in the Caribbean Sea, the Gulf of Mexico, and the Atlantic Ocean. Seismically active areas of the Caribbean Sea region pose a tsunami risk for Caribbean islands, coastal areas along the Gulf of Mexico, and the Atlantic seaboard of North America. Nearly 100 tsunamis have been reported for the Caribbean region in the past 500 years, including 14 tsunamis reported in Puerto Rico and the U.S. Virgin Islands. Partners in this project include the United States Geological Survey (USGS), the Smithsonian Institute, the National Oceanic and Aeronautic Administration (NOAA), and several partner institutions in the Caribbean region. This presentation focuses on the deployment of nine broadband seismic stations to monitor earthquake activity in the Caribbean region that are affiliated with the Global Seismograph Network (GSN). By the end of 2006, five stations were transmitting data to the USGS National Earthquake Information Service (NEIS), and regional partners through Puerto Rico seismograph network (PRSN) Earthworm systems.

    Full Text Available Reducing uncertainty of terrestrial carbon cycle depends strongly on the accurate estimation of changes of global forest carbon stock. However, this is a challenging problem from either ground surveys or remote sensing techniques in tropical forests. Here, we examine the feasibility of estimating changes of tropical forest biomass from two airborne lidar measurements of forest height acquired about 10 yr apart over Barro Colorado Island (BCI, Panama. We used the forest inventory data from the 50 ha Center for Tropical Forest Science (CTFS plot collected every 5 yr during the study period to calibrate the estimation. We compared two approaches for detecting changes in forest aboveground biomass (AGB: (1 relating changes in lidar height metrics from two sensors directly to changes in ground-estimated biomass; and (2 estimating biomass from each lidar sensor and then computing changes in biomass from the difference of two biomass estimates, using two models, namely one model based on five relative height metrics and the other based only on mean canopy height (MCH. We performed the analysis at different spatial scales from 0.04 ha to 10 ha. Method (1 had large uncertainty in directly detecting biomass changes at scales smaller than 10 ha, but provided detailed information about changes of forest structure. The magnitude of error associated with both the mean biomass stock and mean biomass change declined with increasing spatial scales. Method (2 was accurate at the 1 ha scale to estimate AGB stocks (R2 = 0.7 and RMSEmean = 27.6 Mg ha−1. However, to predict biomass changes, errors became comparable to ground estimates only at a spatial scale of about 10 ha or more. Biomass changes were in the same direction at the spatial scale of 1 ha in 60 to 64% of the subplots, corresponding to p values of respectively 0.1 and 0.033. Large errors in estimating biomass changes from lidar data resulted from the uncertainty in detecting changes at 1 ha from ground

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". A concentração de amônia medida no interior de ambas as instalações ficou dentro do limite de conforto. O índice de temperatura e umidade do galpão recoberto com telhas de cerâmica apresentou valores maiores que do galpão recoberto com telha de cimento amianto, mesmo se verificando temperaturas de superfície menores nas telhas de cerâmica, evidenciando os efeitos positivos do lanternim na instalação. Com base nos resultados desta pesquisa, recomendam-se, para a região de Bastos, SP, que os aviários para galinhas de postura sejam construídos com lanternim e prolongamento do beiral e que sejam recobertos com telhas de cerâmica.Poulty house typology and the materials used (mainly for roofing are the determining factors for an appropriate thermal condition aiming at production. In this context, the main point of this paper was to identify differences in the internal environment of two poultry houses, using monitoring and afterwards using statistics for comparing the environmental variables. The data analyzed did not show evidence of better thermal comfort for the house which was covered with ceramic roofing tile, because this house did not have ridged vents, making the hot air exit from the house difficult by the "chimney effect". The ammonia concentration measured inside both houses was within the comfort limit. The temperature and humidity index

    Full Text Available O presente trabalho tem a finalidade de estudar o comportamento de triatomíneos no interior de ecótopos artificiais. Para tanto, construiu-se galinheiro experimental com paredes internas formadas por blocos de barro desmontáveis, abrigando aves como fonte alimentar. O galinheiro foi subdividido em 4 áreas, duas destas separadas por telas e tijolos furados, sendo a menor o local de soltura dos triatomíneos e a maior o galinheiro propriamente dito. Dessa maneira buscou-se a coleta de informaç��es a respeito do deslocamento, sobrevida e locais de abrigo de ninfas do 4º estádio de Triatoma brasiliensis, na certeza de que os mesmos iriam se acomodar nas proximidades da fonte alimentar. As paredes do galinheiro foram desmontadas e pesquisadas mensalmente durante 6 meses e as ninfas encontradas, marcadas com diferentes cores de acordo com o mês da leitura e a posição das mesmas nas áreas. Os resultados alcançados mostraram que 88,5% das ninfas estavam engorgitadas e foram encontradas próximas ao local de repouso (poleiro da fonte alimentar. Após a primeira alimentação, não abandonavam as proximidades da fonte. Os resultados alcançados apresentam, não apenas interesse epidemiológico, como também interesse na área de controle dos vetores da doença de Chagas, tendo em vista as possíveis implicações quanto aos procedimentos na aplicação do inseticida.In order to study the behavior of triatomine bugs under artificial ecotopic conditions, an experimental, double-walled poultry coop was built. Its inside walls were made of sun-dried clay blocks which could be broken apart for better access to the insects hiding in their crevices. The coop was subdivided into two main areas of different sizes using wire netting and a wall made of perforated bricks. The chickens, the only food source available for the triatomines, were kept in the larger, rectangular area, further subdivided diagonally. The triatomines were released in the

    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

    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

    Existing literature related to effects of health on economic growth often consider health variable itself only, and this problem of missing variables by omitting other related factors could well cause doubts about their conclusions, or often only considers one aspect of health, either initial health level or health improvement rate, while these different dimensions of health both could well have effects on economic growth. Basied on these problems of missing variables, and in light of contributions by Nelson-Phelps, Lucas and Barro, this article extends a unified framework and uses international data to comprehensively estimate health effects on economic growth. It finds that a higher initial level and a higher rate of improvement in health both have significantly positive effects on economic growth, and omitting other initial factors or only considering level or improvement rate of health will underestimate health effects on growth. The convergence clubs could be well diminished when initial human capital is controlled (including both health and education levels). These above conclusions are consistent both with OLS and IV methods.%已有文献在考虑健康对经济增长影响时常常只考虑健康因素本身,而忽略其他相关因素从而产生“遗漏变量”问题而影响结论的可信性;或者只考虑健康因素的单一维度,而忽略初始健康水平以及健康水平改善速度都有可能同时影响经济增长.本文基于此,借鉴Nelson-Phelps,Lucas与Barro的方法,构建统一框架并利用跨国数据综合考察健康对经济增长的影响.结论发现,即使在控制其他影响因素后,预期寿命初始水平以及增长速度都对经济增长有显著的正向影响;已有文献中忽略其他条件或者只考虑健康状况的一个维度,都很有可能低估健康对经济增长的实际影响;此外,经济增长“俱乐都”现象与低收入国家初始人力资本水平(包括健康状况与受教育水平)密

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

  14. Materia y Pobreza = Matter and Poverty

    Directory of Open Access Journals (Sweden)

    2013-10-01

    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.

    equilibrio. CONCLUSIONES: La relación negativa entre el plomo y la habilidad visomotora concuerda con los resultados encontrados en niños en otros países. Al parecer las concentraciones de plomo en sangre, que son comunes en los niños de Oaxaca, son suficientes para ocasionar una limitación visomotora de naturaleza sutil. Los resultados de este estudio señalan la necesidad de reforzar la iniciativa de reducir la exposición de los niños a las fuentes de exposición conocidas, en especial barro vidriado y, por lo tanto, reducir los niveles poblacionales de plomo en sangre.OBJECTIVE: To assess the association betwen blood lead concentrations and visual-motor coordination and equilibrium in school age children. MATERIAL AND METHODS: In November-December 1998, a cross-sectional study was conducted among 255 children aged 8-10, who attended public schools in Sector 1 of the Oaxaca State Public Education Institute. Data were collected using the Frostig Evaluation of Visual Perception test and the equilibrium subscale of the Frostig Movement Skills Test Battery. A blood sample was taken to measure lead levels by atomic absorption spectrometry. Socioeconomic data and health histories were collected for use as control variables. Statistical analysis consisted of multiple regression models to test the relationship between blood lead level and the visual-motor and equilibrium tests. We assessed the efect of lead within the model using 1 000 Montecarlo simulations. RESULTS: The geometric mean of blood lead concentrations was 11.5 µg/dl (geometric standard deviation +6.3, -5.2. After adjusting for control variables, the visual-motor integration subscale was significantly related to blood lead concentration (p> 0.042. The visual-motor integration value decreased 1.78 (95% CI -3.51, -0.06 points for each 10 µg/dl increase in blood lead concentration. Among the four sub-tests comprising the visual-motor integration subscale, only eye-hand coordination (p=0.045 and spatial relations

    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,

    implementation. This paper examines the private adaptation capacity and willingness in two different catchments in the Mediterranean. The catchments Evros and Rafina in Greece were affected by flood events during the past 20 years. However, even in case of extreme events, the vulnerability of the (social) system to stress is considerably low due to social networks, economic settings as well as institutional and political factors, and consequently the speed of return to the equilibrium steady state, defined as the prevailing livelihood conditions, is fast. In other words, even if the magnitude of a hazardous event is high, the vulnerability is considerably low due to multiple compensation mechanisms installed in the Greek society, ranging from spreading risk to a larger community to governmental compensation and private donation. Therefore, ex-post recovery following an event is well-organised, and the initial systems state is re-established immediately or with only little delay. Therefore, affected citizens simply do not care much about being affected by floods, will be able to prevent those damages. There are no incentives for the affected population to react pro-active by e.g. investing in local structural protection or any other management strategy.

    course of this study is characterized under the name of Salmonella nocardi. The author believes that in the epizooty from which Nocard isolated his bacterium there was association of the virus-disease inducing the epizooty of that epoch in Paris with the bacterial disease, as must have happened in Argentina, where the disease was transmitted to man, and Santillan, according to Barros, isolated from the sick parrots bacteria of the genus Salmonella. The diseases of the two groups, that due to virus and that due to bacteria, are differentiated: Virus-diseases - Evolution: rapid, nearly always followed by death. Symptoms: sadness, profuse diarrhoea, of whitish stools, at times enterorrhagia, complete inappetency, adynamia, indifference, prolonged coma. Clinical forms: acute and subacute. Lesions: Foci of necrosis in liver and spleen without cellular reaction around the focus, yellow liver, multiple serositis. Presence of protoplasmic or nuclear granulations. Bacteriology: Complete lack or inconstant presence of bacteria in the organs and blood. Infectiousness of the organs and blood after filtration: positive. Bacterial diseases - Varies from one week to a month or more, not always fatal. Sadness, partial inappetency, tremblings, intensive thirst, mucous or mucosanguineous diarrhoea, lack of adynamia (reacts to stimulations and moves well at any time of the disease, though showing little disposition to locomotion, soiling of feathers. Frustrate, acute, subacute and chronic. Hepatic and intestinal cogestion, foci of necrosis in liver, spleen and lung with cellular reaction around the focus. Lack of granulations. Constant presence of bacteria in the organs and blood. Negative. The analysis of the litterature shows that the characteristic features of the diseases in parrots referred to parrot psittacosis, more frequently approach the bacterial diseases here described of these animals, a hypothesis which is reinforced by the observation of the greater frequency of infections...

    Full Text Available ResumenDefiniendo Asís Cabrero la arquitectura como un arte visual-utilitario, se remonta a los orígenes de la especie para explicar cuáles son elementos de la consciencia que intervienen en la obra del hombre. La táctica de supervivencia humana se basa en una técnica voluntaria, variable, personal e inventiva, en contraste con el instinto de los demás seres de la naturaleza. A este animal rapaz, cuyo pensamiento está determinado por su sentido de la vista, se le añade la inteligencia que proviene de la habilidad de la mano para fabricar herramientas. Este animal de órganos intercambiables es capaz de especializarse con cada una de las herramientas que construye para igualarse a cada uno de los animales especializados. Así, el hombre construye herramientas para hacer frente a una naturaleza variable y cambiante, ya sea un cuchillo, un hacha o un refugio.Siendo la arquitectura causa del sentir óptico, es principalmente el pensamiento útil de la mano el que interviene en la elaboración de la arquitectura. Para Cabrero, la materia se convierte en material a través de la herramienta, para ser aparejado, para poder construir. Son las herramientas las que evolucionan a lo largo de la historia, permaneciendo la materia siempre igual en la naturaleza. Asís Cabrero investiga cinco arquitecturas primitivas relacionadas con cinco materias primeras. Así, estudia la estructura cupular, el dintel, el entramado, la estructura laminar y la estructura desmontable en relación con el uso racional del barro, la piedra, la madera, el ramaje y la piel.La diversa disponibilidad material en la trayectoria profesional de Asís Cabrero, desde el aislamiento de la posguerra a la apertura de los años sesenta, hace que podamos establecer diferentes edades en la obra de Francisco de Asís Cabrero según el material y las herramientas que utiliza.Palabras claveFrancisco Cabrero, arquitectura, instrumentos, material, estructura, herramientas

    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.

    Las paredes maestras y la fachada de la iglesia de San Francisco, no obstante el deterioro, atestiguaban todavía la vana ilusión de construir para la eternidad que anima a ciertas empresas humanas. La iglesia de Nuestra Señora del Rosario, resto intacto de la fundación dominicana, era la

    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

    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.

    the nucleus jumps from the first excited level to the fundamental, or ground, level). This light is emitted in the ultraviolet, at 121.6 nm. The Lyman-alpha line is the first in the so-called Lyman series, named after its discoverer, Theodore Lyman. The Balmer series, named after Johann Balmer, also corresponds to light emitted by excited hydrogen. In this case, the electron falls into the first excited level. The first line in this series is the H-alpha line, emitted at 656.3 nm. As most hydrogen atoms present in a galaxy are in the ground level, Lyman-alpha light is more efficiently absorbed than H-alpha light, which requires atoms having an electron in the second level. As this is very uncommon in the cold interstellar hydrogen permeating galaxies, the gas is almost perfectly transparent to H-alpha light. [2] A narrowband filter is an optical filter designed to let pass only a narrow bandwidth of light, centred on a specific wavelength. Traditional narrowband filters include those centred on the lines of the Balmer series, such as H-alpha. [3] Because the Universe expands, the light of a distant object is redshifted by an amount depending on its distance. This means its light is moved towards longer wavelengths. A redshift of 2.2 - corresponding to galaxies whose light has taken approximately 10 billion years to reach us - means that the light is stretched by a factor 3.2. Thus the Lyman-alpha light is now seen at about 390 nm, near the visible domain, and can be observed with the FORS instrument on ESO's VLT, while the H-alpha line is moved towards 2.1 microns, in the near-infrared. It can thus be observed with the HAWK-I instrument on the VLT. More information This research was presented in a paper to appear in Nature ("Escape of about five per cent of Lyman-a photons from high-redshift star-forming galaxies", by M. Hayes et al.).

    ções para leitura dirigida por um roteiro estruturado. Para segunda etapa, empregou-se a técnica de painel interativo, tendo sido validados os marcos conceituais do cuidado com famílias em atenção primária. A convergência dos saberes foi apresentada segundo os padrões de conhecimento - empírico, ético, pessoal e estético, de Chinn e Kramer¹, e - sócio-político, de White². Os padrões de conhecimento ético e estético encontraram-se exíguos, em relação a uma declaração explícita deles, pelos pesquisadores participantes do estudo. Uma vez que o padrão ético esteve presente em apenas dois dos sete trabalhos analisados, oferece, portanto, uma lacuna para estudos posteriores, por se tratar do componente moral de tomada de decisões pelo enfermeiro. Como propósito, construiu-se um guia prático para utilização no cuidado com famílias em atenção primária, na perspectiva de sugerir a enfermeiros e estudantes da Enfermagem uma ferramenta para adoção de uma postura reflexivo-crítica diante do cuidado humano. Considerou-se que o saber popular e o conhecimento acadêmico são convergentes, estão integrados e integrando o cuidado de Enfermagem e respondem a demanda de atenção primária de saúde das famílias.La familia ha sido priorizada por medio de programas sociales, en especial, con la descentralización de las acciones de salud.

Es una obra en la cual se ven las múltiples facetas del Dr. Evaristo como médico, historiador, botánico, químico, nutricionista, comerciante, investigador, y «chef de cuisine». Desde el punto de vista de la botánica describe los diferentes caracteres del plátano, sus orígenes y controversias, las opiniones del sabio Humboldt sobre su riqueza alimenticia y extensión de su cultivo en las Américas y otros continentes.

    mais graves problemas urbanos, sendo um dos principais responsáveis pelo comprometimento da qualidade ambiental em diversas áreas densamente ocupadas. Conforme os espaços urbanos são edificados sem um planejamento que considere a manutenção e/ou criação de mecanismos que gerem amenidades ambientais (por exemplo, áreas verdes e estabelecimento de padrões de ocupação do solo que favoreçam a circulação intra-urbana do ar, mais a população desses locais estará exposta à situações que causem prejuízos a sua saúde. Contudo, propor alternativas é assumir a necessidade de romper não somente com modelos produtivos impactantes, como também com estilos de vida. Costuma-se destacar como um dos grandes desafios para implementação de medidas que visam a melhoria da qualidade ambiental em áreas urbanas, o fato de que por 201 Anuário do Instituto de Geociências - UFRJ Volume 25 / 2002 ser um espaço construído, intervenções seriam extremamente difíceis de serem realizadas. Todavia, esse argumento possui falhas, pois o espaço urbano não é estático, principalmente nas grandes metrópoles. O dinamismo do desenho urbano é uma característica do próprio sistema capitalista que na sua busca pela ampliação acumulada de capital, modifica formas e funções de espaços, gerando fluxos e criando condições de vida diferenciadas de acordo com a situação econômica de cada grupo. É dentro desse contexto socialmente complexo, caracterizado por choques de interesses, que se analisa no presente estudo a qualidade do ar no Município do Rio de Janeiro, ressaltando todas as suas implicações na saúde da população carioca e identificando os principais fatores geoecológicos responsáveis pela distribuição das concentrações de material particulado.

    interpretação leva à ocorrência de episódios de inundação prolongada da planície fluvial entrelaçada, provavelmente gerados por barramentos tectônicos da paleodrenagem. Os leques aluviais desenvolvidos na periferia do maciço do Morro Redondo, bem como a localização do sistema fluvial "Acácias" junto à borda sul da bacia, sugerem o início de um processo de perda de assimetria do hemi-gráben, proporcionado por atividade tectônica mais vigorosa na borda sul, que teria gerado a elevação do Morro Redondo e a subsidência da região onde fluía aquele sistema fluvial. Este processo de perda de assimetria do hemi-gráben não teria chegado a evoluir significativamente, visto que a próxima etapa da evolução da bacia foi representada pela implantação de um sistema fluvial meandrante (Associação de Fácies 6, cujos depósitos foram aqui incluídos na Formação Floriano. Esse sistema fluvial representou o preenchimento final da bacia de Resende, tendo este se desenvolvido tanto sobre a Formação Resende, como sobre o embasamento cristalino do alto estrutural de Resende.
