    2008-01-01

    In 1973, the Canadian government took measures to place oil exports under federal control and placed a freeze on oil prices. Prime Minister Pierre Trudeau unveiled plans for a national energy policy that would dissolve the Borden policy which prevented western Canadian crude from accessing the Montreal refining market. Trudeau's policy would extend the oil price freeze and created a one-price national market for Canadian oil. Plans were also underway to create a national oil company that would stimulate exploration and exploitation of new energy resources. The Premier of Alberta was also implementing energy regulations at the same time, aimed at consolidating control of Alberta's own resources within the framework of the Constitution and preventing Ottawa from gaining full control of all of Alberta's energy resources. Other key events in 1973 were the introduction of Saskatchewan's Oil and Gas Conservation, Stabilization and Development Act which gave the province the right to take over the oil rights of all private companies in producing areas. The Polar Gas Project was created to conduct research into building a gas pipeline from the Arctic Islands, and a Canadian Arctic gas study revealed that the Mackenzie Pipeline could be delivering gas by 1977. 1 tab., 1 fig

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

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

  9. Foraging Behavior of Odontomachus bauri on Barro Colorado Island, Panama

    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.

    Full Text Available Apesar de problemáticas, as noções de “primitivo” e “primitivismo” foram categorias essenciais para a arte e a arquitetura moderna na América Latina, tanto para produtores (arquitetos e artistas, quanto para seus intérpretes (historiadores e críticos. Estiveram fortemente associadas tanto à contribuição latino-americana para uma modernidade universal quanto à apreciação historiográfica dessa contribuição. Este texto tem por objetivo cercar determinados “usos do primitivismo” na arquitetura sul-americana, que coincidem com a presença de materiais naturais, como a pedra e o barro, e de técnicas construtivas pré-industriais. Embora essa presença possa ser discutida apenas nos termos de uma relação com o “vernáculo”, adota-se propositalmente a noção de “primitivismo”, por exibir um impasse (de certa forma indiferente ao vernáculo de uma ligação intelectual, e não natural, com a tradição.

    The Barro Alto Complex comprises a highly deformed and metamorphosed association of plutonic, volcanic, and sedimentary rocks exposed in a 150 x 25 Km boomerang-like strip in Central Goias, Brazil. It is the southernmost tip of an extensive yet discontinuous belt of granulite and amphibolite facies metamorphic rocks which include the Niquelandia and Cana Brava complexes to the north. Two rock associations are distinguished within the granulite belt. The first one comprises a sequence of fine-grained mafic granulite, hypersthene-quartz-feldspar granulite, garnet quartzite, sillimanite-garnet-cordierite gneiss, calc-silicate rock, and magnetite-rich iron formation. The second association comprises medium-to coarse-grained mafic rocks. The medium-grade rocks of the western/northern portion (Barro Alto Complex) comprise both layered mafic rocks and a volcanic-sedimentary sequence, deformed and metamorphosed under amphibolite facies conditions. The fine-grained amphibolite form the basal part of the Juscelandia meta volcanic-sedimentary sequence. A geochronologic investigation by the Rb-Sr method has been carried out mainly on felsic rocks from the granulite belt and gneisses of the Juscelandia sequence. The analytical results for the Juscelandia sequence are presented. Isotope results for rocks from different outcrops along the gneiss layer near Juscelandia are also presented. In conclusion, Rb-Sr isotope measurements suggest that the Barro Alto rocks have undergone at least one important metamorphic event during Middle Proterozoic times, around 1300 Ma ago. During that event volcanic and sedimentary rocks of the Juscelandia sequence, as well as the underlying gabbro-anorthosite layered complex, underwent deformation and recrystallization under amphibolite facies conditions.

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.

  6. Ark and Archive: Making a Place for Long-Term Research on Barro Colorado Island, Panama.

    Raby, Megan

    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.

  8. 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

  9. The Butterflies of Barro Colorado Island, Panama: Local Extinction since the 1930s.

    Full Text Available 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.

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.

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.

    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.

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

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

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

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

    Science.gov (United States)

    2011-01-01

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

    Rb-Sr geochronologic investigation carried out on rocks from the Barro Alto Complex, Goias, yielded iso chronic ages of 1266 +- 17 Ma, for felsic rocks from the granulite belt and 1330 +- 67 Ma, for gneisses belonging to the Juscelandia Sequence. Rb-Sr isotope measurements suggest that Barro Alto rocks have undergone an important metamorphic event during middle Proterozoic times, around 1300 Ma ago. During that event, volcanic and sedimentary rocks of Juscelandia Sequence, as well as the underlying gabbros-anorthosite layered complex, underwent deformation and recrystallization under amphibolite facies conditions. Deformation and metamorphism took place during the collision of two continental blocks, which resulted in a southeastward directed thrust complex, allowing the exposure of granulite slices from the middle-lower crust of the overthrusted block.

    Tapirs are known as effective dispersers of large-seeded tree species, but their role in dispersing small-seeded plant species has yet to be established. Tapir feces have been reported to contain large numbers of small seeds, but whether these are viable has rarely been evaluated. We determined the abundance and viability of small seeds in feces of Central American tapir (Tapirus bairdii) on Barro Colorado Island, Panama. A total of 72 fecal samples were collected opportunistically from 4 tapir latrine sites. Seeds were manually extracted from feces and classified by size. Seed viability was estimated by opening each seed and examining for the presence of at least 1 intact firm white endosperm. In total, we obtained 8166 seeds of at least 16 plant species. Small-seeded species dominated, with 96% of all seeds found measuring tapirs potentially serve as effective dispersers of a wide range of small-seeded plant species. © 2012 Wiley Publishing Asia Pty Ltd, ISZS and IOZ/CAS.

    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.

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

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

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

    Full Text Available O presente trabalho tem como objetivo avaliar a qualidade da água, através de análises da qualidade físico-químicas e microbiológicas, ciente de que o açude é de grande importância para os moradores da cidade, que utilizam a água do mesmo para lazer, dessedentação de animais, pesca e lavagem de roupas. A pesquisa foi realizada no município de Barro- CE, mais precisamente no açude do Cumbe as margens da BR-116, tendo como finalidade a realizações de analises físico-químicas e microbiológicas, durante o mês de setembro a novembro de 2010, no período da manhã, sendo definido 3 pontos amostrais ao longo do açude, perfazendo o total de 5 coletas todas no início da manhã. Dentre os parâmetros realizados foram: pH, CE, OD, DBO, Dureza, Cloretos, amônia, e ortofosfato, e microbiológicas (coliformes totais e fecais. Os resultados obtidos nas análises foram comparados com os estabelecidos pela Resolução CONAMA n° 357/2005 e pela Resolução CONAMA n°274/2000 e ainda pela Portaria 518 do ministério da saúde. A comparação dos resultados possibilita dizer que o açude apresenta elevado teor de poluição devido seus valores não estarem inseridos dentro dos valores aceitáveis pelas resoluções vigentes.

    Full Text Available Introducción: el tratamiento endodóntico realiza la limpieza y conformación del sistema de conductos radiculares, ya que virutas de dentina y materiales orgánicos, como los microorganismos, creadas por la acción de la instrumentación, forman el llamado barro dentinario. Objetivo: evaluar in vitro la remoción del barro dentinario y la disminución de la densidad de túbulos dentinarios, con soluciones irrigadoras quelantes. Métodos: se trata de un estudio experimental para el cual fueron seleccionados 30 dientes unirradiculares de humanos después del examen radiográfico inicial, y en el que se constató la presencia de canal único, ausencia de calcificación, reabsorción interna y tratamiento endodóntico concluido o en proceso. Luego se procedió a la instrumentación con tres diferentes soluciones irrigadoras: ácido etilenodiaminetetracético 17 %, ácido cítrico 10 % e hipoclorito de sodio 5,25 % (grupo control. Posteriormente se evaluó radiográficamente cada diente instrumentado con el uso de una escala de densidad que fue confeccionada de aluminio con diferentes marcadores de densidades. Para el análisis por microscopio electrónico de barrido se utilizaron tres dientes de cada grupo, tratados con diferentes soluciones irrigadoras. Siete dientes de cada grupo se infiltraron con azul de metileno para la lectura de la infiltración marginal en el microscopio estereoscópico. Los dientes fueron evaluados en sus tres tercios: cervical, medio y apical. Resultados: se encontró que radiográficamente no hubo diferencia estadísticamente significativa entre los promedios de las densidades de los grupos de dientes en todos los tercios. Por microscopio electrónico de barrido se encontró una diferencia estadísticamente significativa entre los tres grupos de sustancias irrigadoras (p < 0,001, en el tercio cervical la remoción del barro dentinario fue mayor. Y por microscopio óptico se observó una mayor infiltración en el grupo

    Franco L. Souza

    Full Text Available The Rufous Hornero (Furnarius rufus is one of the most common bird species in Brazil. Anecdotal information indicates that nest opening orientation in this species is contrary to wind or rainfall direction. To check for the existence of such a pattern, F. rufus nests were randomly sampled within an urban area in central Brazil to assess whether factors such as wind and vegetation cover influence nest opening orientation. Using circular statistics, no evidence was found that nest-opening orientation was important for the species. These results refuse the expected pattern for tree hollow or enclosed nests. The results suggest that factors such as nesting architecture, nest material, nest microclimate or a combination of these, instead of local climate, must be conditioning nesting behavior in this species.O joão-de-barro (Furnarius rufus é uma das espécies de aves mais comuns do Brasil. Informações sugerem que a orientação da abertura dos ninhos desse furnarídeo seria direcionada em posição contrária das direções de incidência dos ventos e das chuvas. Para averiguar tal padrão de nidificação, ninhos de F. rufus foram aleatoriamente amostrados em uma área urbana da região Centro-Oeste do Brasil para verificar se fatores como vento e cobertura vegetal exerciam influência sobre a orientação de suas aberturas. Testes envolvendo estatística circular revelaram que a abertura dos ninhos refletiu um padrão aleatório de orientação, algo não esperado para aquelas espécies que nidificam em ocos de árvores ou que constroem seus ninhos de maneira a proteger a câmara de incubação. Ao invés do clima da região, os resultados sugerem que a arquitetura e o material de construção do ninho, o microclima dentro do ninho ou uma combinação desses fatores possam estar condicionando o comportamento de nidificação dessa espécie.

    Full Text Available Traditional rural buildings reflect the building techniques inherited from ancestors, where materials mastery is proved. In this job we analyse the structure of one of the most relevant Spanish traditional agrarian building: the "casa de corral"(yard house. Thirty seven "corrales" (yards of the vernacular earthen construction in the "Páramo de León"(León, Spain were analysed. It was necessary think up an analysis method, which we called "round analysis method". Generally. radial cross sections of the yard have a main space between two earth walls bearing over stone foundation, which support floor framing, the roof framing, roof sheathing and arabic curved tiles. A gantry is usually built inward the yard, on a stone baseLas construcciones rurales tradicionales suelen reflejar el buen hacer de quienes han heredado las técnicas de sus antepasados, demostrando un dominio admirable de los materiales. En este trabajo nos centramos en el análisis estructural de uno de los edificios más emblemáticos de las construcciones agrarias tradicionales peninsulares: la casa de corral. Se analizaron 37 de estos edificios, uniformemente repartidos por la comarca del Páramo de León (España. pertenecientes a la denominada construcción de barro rural tradicional contemporánea. Para llevar a cabo el estudio fue necesario idear el denominado método giratorio de análisis. en virtud del cual se realizan sucesivos cortes radiales al corral. Esto nos permitió establecer las características constructivas más relevantes de dichos edificios. En general. las secciones radiales del corral suelen contar con un volumen principal de gruesos muros de carga a base de tapial sobre cimiento de piedra. sustentando los forjados y la estructura de cubierta, cuya impermeabilidad se logra mediante teja árabe. dispuesta sobre enlabiado de madera o sobre rama entretejida.

Chega-se à conclusão de que essa convergência tem por objetivo apresentar a matéria de poesia dos poetas: a eleição do elemento prosaico. É ressaltado que os dois poetas, ao elevarem ao estatuto de poesia elementos pouco nobres, ao fazerem da crítica a matéria fundamental de sua poesia, estariam renovando uma poesia que não se vale de tais elementos.Palavras-chave: Crítica.

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

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

En este artículo, trataremos de ver cómo y por qué se fragua en el cuento una visión insoportable del hecho de ser madre, así como una imagen monstruosa del hijo cuya pulsión de vida termina desgastando y debilitando el cuerpo de la mujer a través del amamantamiento forzoso. 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.

A exceção ficaria por conta dos pássaros, que se furtam ao padrão de apreciação dos bichos já referidos. O presente trabalho busca,de início, evidenciar a poesia do escritor como espaço de inclusão do que muitas vezes é tomado como repulsivo,evidenciando o sentido de metamorfose da arte, enquanto terreno da outridade; em segundo lugar, interessa ver como a figura do animal, em sua atuação no mundo natural, funciona como suporte para a dicção metanarrativa que impregna todo o relato, sendo, portanto, de suma importância, uma vez que as Memórias situam-se no domínio da poeisis.

  5. Political pugilists: recuperative gender strategies in canadian electoral politics.

    Science.gov (United States)

    Maiolino, Elise

    2015-05-01

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

    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.

  12. Breathing response of the tegu lizard to 1-4% CO2 in the mouth and nose or inspired into the lungs.

    Ballam, G O

    1985-12-01

    This study investigated the influence on ventilation of elevated CO2 in the nasal and buccal cavities (NaBuCO2) vs the effect of elevated CO2 levels inspired into the lungs (LuCO2). Separate gas sources were used to independently alter NaBuCO2 and LuCO2. As little as 1% NaBuCO2 or LuCO2 significantly increased the pause duration between the active expiratory-inspiratory cycles. Elevated NaBuCO2 caused minor changes in tidal volume, mean inspiratory and expiratory flow, and inspiratory and expiratory durations with a significant reduction in total ventilation. Elevated LuCO2 had little effect on inspiratory or expiratory durations but unlike CO2 in the upper airways, significantly increased tidal volume and mean inspiratory and expiratory flows. This study demonstrates that the increased pause duration seen in the tegu lizard to elevated environmental CO2 is due to a receptor response in the buccal or nasal cavities and also to elevated CO2 concentrations inspired into the lungs. Sensitivity of the ventilatory responses to CO2 in the upper airways is well within a physiologically relevant range.

  14. An Efficient Numerical Method for Computing Synthetic Seismograms for a Layered Half-space with Sources and Receivers at Close or Same Depths

    Science.gov (United States)

    Zhang, H.-m.; Chen, X.-f.; Chang, S.

    - It is difficult to compute synthetic seismograms for a layered half-space with sources and receivers at close to or the same depths using the generalized R/T coefficient method (Kennett, 1983; Luco and Apsel, 1983; Yao and Harkrider, 1983; Chen, 1993), because the wavenumber integration converges very slowly. A semi-analytic method for accelerating the convergence, in which part of the integration is implemented analytically, was adopted by some authors (Apsel and Luco, 1983; Hisada, 1994, 1995). In this study, based on the principle of the Repeated Averaging Method (Dahlquist and Björck, 1974; Chang, 1988), we propose an alternative, efficient, numerical method, the peak-trough averaging method (PTAM), to overcome the difficulty mentioned above. Compared with the semi-analytic method, PTAM is not only much simpler mathematically and easier to implement in practice, but also more efficient. Using numerical examples, we illustrate the validity, accuracy and efficiency of the new method.

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

    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.

    This dissertation provides a history of Canadian ideas about nuclear weapons from the late 1950s until the end of the Trudeau era in 1984. Throughout this period, Canadians reacted to the insecurity they felt in the world around them by expressing many conflicting, often irreconcilable views about a range of nuclear weapon issues, including Canada's acquisition of nuclear warheads in 1963, the U.S. ABM program in the 1960s and early 1970s, the role of Canadian nuclear technology in the development of India's first nuclear explosion, and the Trudeau government's decision to allow the U.S. military to test cruise missiles in northern Canada The dissertation concludes with an examination of the emergence of a broadly-based, increasingly mainstream and influential anti-nuclear movement in the early 1980s, the clearest manifestation of the insecurity Canadians experienced at the time. .The nuclear debates examined in this dissertation reveal that Canadians were divided over nuclear weapons, nuclear strategy, the arms race, proliferation, and arms control and disarmament. In particular, they came to fundamentally different conclusions about how Canada's nuclear weapon policies, and its support for the nuclear policies of its alliances, would contribute to international stability and order. Some believed that their security rested on the maintenance of a strong Western nuclear deterrent and supported Canada contributing to its credibility; others believed that the constant modernisation of nuclear arsenals fuelled by the superpower arms race posed a serious threat to their security. This conceptual dilemma-the security through nuclear strength argument versus the fear that the quest for security through quantitative and qualitative improvements of nuclear stockpiles increased the likelihood of nuclear war-left Canadians divided over the value and utility of nuclear weapons and the strategies developed around them.

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

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

  6. Species loss, delayed numerical responses, and functional compensation in an antbird guild.

    Science.gov (United States)

    Touchton, Janeene M; Smith, James N M

    2011-05-01

    When a community loses species through fragmentation, its total food consumption may drop. Compensatory responses of remaining species, whereby survivors assume roles of extinct competitors, may reduce the impact of species loss through numerical or functional responses. We measured compensatory responses in two remaining antbird species on Barro Colorado Island, Panama, four decades after the loss of their dominant competitor, the Ocellated Antbird, Phaenostictus mcleannani. We compared current abundances and behavior of these two species on Barro Colorado to those reported before the island lost Ocellated Antbirds, and to those in a nearby mainland population where all three species still exist as a space-for-time substitution. The smaller, more subordinate Spotted Antbird, Hylophylax naevioides, responded far more strongly than the larger Bicolored Antbird, Gymnopithys leucaspis, which is functionally more like the Ocellated Antbird. Islandwide density of Spotted Antbirds has more than doubled since the loss of Ocellated Antbirds. Moreover, Spotted Antbirds now spend so much more of their time following ant swarms that their metabolic biomass at these swarms has more than tripled since Ocellated Antbirds disappeared. These responses in Spotted Antbirds were apparently delayed by >20 years. Bicolored Antbirds have not increased substantially in islandwide density or metabolic biomass at ant swarms. We hypothesize that behavioral flexibility, as shown by Spotted Antbirds on Barro Colorado Island, is a major factor governing the extent to which fragmented ecosystems can buffer the impacts of species loss.

  7. Variational functionals which admit discontinuous trial functions

    International Nuclear Information System (INIS)

    Nelson, P. Jr.

    1975-01-01

    It is argued that variational synthesis with discontinuous trial functions requires variational principles applicable to equations involving operators acting between distinct Hilbert spaces. A description is given of a Roussopoulos-type variational principle generalized to cover this situation. This principle is suggested as the basis for a unified approach to the derivation of variational functionals. In addition to esthetics, this approach has the advantage that the mathematical details increase the understanding of the derived functional, particularly the sense in which a synthesized solution should be regarded as an approximation to the true solution. By way of illustration, the generalized Roussopoulos principle is applied to derive a class of first-order diffusion functionals which admit trial functions containing approximations at an interface. These ''asymptotic'' interface quantities are independent of the limiting approximations from either side and permit use of different trial spectra at and on either side of an interface. The class of functionals derived contains as special cases both the Lagrange multiplier method of Buslik and two functionals of Lambropoulos and Luco. Some numerical results for a simple two-group model confirm that the ''multipliers'' can closely approximate the appropriate quantity in the region near an interface. (U.S.)

    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 gap, V oc, and V 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 ex), the maximal absorption wavelength (λmax), 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.

  9. Modeling Anti-HIV Activity of HEPT Derivatives Revisited. Multiregression Models Are Not Inferior Ones

    2007-01-01

    Several quantitative structure-activity studies for this data set containing 107 HEPT derivatives have been performed since 1997, using the same set of molecules by (more or less) different classes of molecular descriptors. Multivariate Regression (MR) and Artificial Neural Network (ANN) models were developed and in each study the authors concluded that ANN models are superior to MR ones. We re-calculated multivariate regression models for this set of molecules using the same set of descriptors, and compared our results with the previous ones. Two main reasons for overestimation of the quality of the ANN models in previous studies comparing with MR models are: (1) wrong calculation of leave-one-out (LOO) cross-validated (CV) correlation coefficient for MR models in Luco et al., J. Chem. Inf. Comput. Sci. 37 392-401 (1997), and (2) incorrect estimation/interpretation of leave-one-out (LOO) cross-validated and predictive performance and power of ANN models. More precise and fairer comparison of fit and LOO CV statistical parameters shows that MR models are more stable. In addition, MR models are much simpler than ANN ones. For real testing the predictive performance of both classes of models we need more HEPT derivatives, because all ANN models that presented results for external set of molecules used experimental values in optimization of modeling procedure and model parameters

    DFT calculation at the B3LYP level was performed on crystalline potassium picrate. The frontier bands are slightly fluctuant. The energy gap between the highest occupied crystal orbital (HOCO) and the lowest unoccupied crystal orbital (LUCO) is 0.121 a.u. (3.29 eV). The carbon atoms that are connected with the nitro groups make up the narrow lower energy bands, with small contributions from nitro oxygen and phenol oxygen. The higher energy bands consist of orbitals from the nitro groups and carbon atom. The potassium bears almost 1 a.u. positive charge. The potassium forms ionic bonding with the phenol oxygen and the nitro oxygen at the same time. The crystal lattice energy is predicted to be -574.40 kJ/mol at the B3LYP level determined with the effective core pseudopotential HAYWSC-31G basis set for potassium and 6-31G** basis set for other atoms.

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

  15. The rise and fall of refineries

    International Nuclear Information System (INIS)

    Chretien, D.

    2002-01-01

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

    Full Text Available RESUMO: O presente trabalho tem por objetivo a leitura do livro Exercícios de Ser Criança (1999, à luz da filosofia de Gaston Bachelard (1884-1962, principalmente pelo significado teórico que a infância toma nas poéticas do Devaneio e do Espaço. Exercícios de ser criança (1999, primeiro livro do poeta Manoel de Barros publicado com a classificação infanto-juvenil, recupera as principais características do programa poético manoelino: a aversão ao utilitarismo da linguagem, o universo infantil como temática central, o devaneio como exercício poético. Assim, temas como brincadeiras, travessuras e o modo próprio de como a criança vive o devaneio são recorrentes em toda a obra. Neste sentido, busca-se compreender como Manoel de Barros, por meio de seu fazer poético, toma a infância como signo de eterno retorno a um tempo que, a priori, é irrecuperável, mas que através dos exercícios poéticos de ser criança, torna-se um espaço permanentemente imóvel, de recordação, de revisitação. A infância como espaço de memória e criação poética. Palavras- Chave: Manoel de Barros. Infância. Poesia Brasileira. Bachelard.

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

    Steady state levels of population and per capita income are examined using a Becker-Barro (1988) style of model of an economy with identical altruistic parents bearing costly children who receive bequests of capital and land. Inspired by the work of North (1981) and others, the problem of open access land with ancillary negative effects on private (but not public) productivity of capital is examined. It is seen that open access to land can lead to overpopulation in a ceteris paribus sense, an...

    We propose a simple and powerful method for determining the transition process in continuous-time DSGE models under Poisson uncertainty numerically. The idea is to transform the system of stochastic differential equations into a system of functional differential equations of the retarded type. We...... classes of models. We illustrate the algorithm simulating both the stochastic neoclassical growth model and the Lucas model under Poisson uncertainty which is motivated by the Barro-Rietz rare disaster hypothesis. We find that, even for non-linear policy functions, the maximum (absolute) error is very...

    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.

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.

    Full Text Available Artificial neural network (ANN approach was used for the prediction of effect of reinforcement and deformation on volumetric wear of red mud nano particle reinforced aluminium matrix composites synthesized by stir casting. Red mud obtained from alumina processing industry was milled in a high energy ball mill and the particle size was reduced to 40 nm in 30 h. Sliding wear characteristics of the composites were evaluated on pin on disc wear tester at different loads of 10 N, 20 N and 30 N and sliding speeds of 200, 400, and 600 RPM. The wear rate of the composite was decreased with increase in weight fraction of red mud up to 10% and beyond that the wear rate was increased. The interfacial area between the matrix and the reinforcement increases with increase in red mud volume fraction, leading to increase in strength and wear resistance. Mathematical regression model and ANN model have been developed to predict theoretical wear rate of the composite and observed that ANN predictions have excellent agreement with measured values than other models. Thus, the prediction of wear rate of the nano composites using artificial neural network before actual manufacture will considerably saves the project time, effort and cost. Resumen: Se utilizó el método de red neuronal artificial (RNA para predecir el efecto del refuerzo y la deformación sobre el desgaste volumétrico de los materiales compuestos de matriz de aluminio reforzada con nanopartículas de barro rojo sintetizados por agitación. El barro rojo obtenido de la industria de procesamiento de alúmina se molió en un molino de bolas de alta energía y el tamaño de la partícula se redujo a 40 nm en 30 h. Las características de desgaste de los materiales compuestos se evaluaron en los probadores pin-on-disk de desgaste en diferentes cargas de 10N, 20N y 30N, y velocidades de deslizamiento de 200, 400 y 600 rpm. El índice de desgaste del material compuesto se redujo con el aumento en

    In Brazil economically important coal deposits occur in the southern part of the Parana 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, Parana 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 (Irapua, 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 Irapua 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 Irapua seam has the highest inertinite content (33.8 vol%). Liptinite mean values range from 7.8 vol% (Barro Branco seam) to 22.5 vol% (Irapua seam). Results from proximate analyses indicate for the three seams high ash yields (50.2 - 64.2 wt.%). Considering the International Classification of in-Seam Coals, all samples are in fact classified as carbonaceous rocks (> 50 wt.% 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

    Pyrosequencing technology, sequencing by addition, was evaluated for categorization of mycobacterial isolates. One hundred and eighty-nine isolates, including 18 ATCC and Trudeau Mycobacterial Culture Collection (TMC) strains, were studied. There were 38 Mycobacterium tuberculosis complex, 27 M. kansasii, 27 MAI complex, 21 M. marinum, 14 M. gordonae, 20 M. chelonae-abscessus group, 10 M. fortuitum, 5 M. xenopi, 3 M. celatum, 2 M. terrae complex, 20 M. mucogenicum, and 2 M. scrofulaceum. Nucleic acid extracts were prepared from solid media or MGIT broth. Traditional PCR was performed with one of the primers biotinylated; the assay targeted a portion of the 16S rRNA gene that contains a hypervariable region, which has been previously shown to be useful for the identification of mycobacteria. The PSQ Sample Preparation Kit was used, and the biotinylated PCR product was processed to a single-stranded DNA template. The sequencing primer was hybridized to the DNA template in a PSQ96 plate. Incorporation of the complementary nucleotides resulted in light generation peaks, forming a pyrogram, which was evaluated by the instrument software. Thirty basepairs were used for isolate categorization. Manual interpretation of the sequences was performed if the quality of the 30-bp sequence was in doubt or if more than 4 bp homopolymers were recognized. Sequences with more than 5 bp of bad quality were deemed unacceptable. When blasted against GenBank, 179 of 189 sequences (94.7%) assigned isolates to the correct molecular genus or group. Ten M. gordonae isolates had more than 5 bp of bad quality sequence and were not accepted. Pyrosequencing of this hypervariable region afforded rapid and acceptable characterization of common, routinely isolated clinical Mycobacterium sp. Algorithms are recommended for further differentiation with an additional sequencing primer or additional biochemicals.

    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.

    2016-09-01

    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.

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

    Full Text Available SCIENTIFIC TRAVELS AND THE DEVELOPMENT OF GEOGRAPHICAL IDEAS IN PORTUGAL DURING THE 19TH CENTURY - The main goal of this paper is to establish the relationship between scientists movements, the circulation of ideas and the appearance of some basic works for modern Portuguese geography, around 1870. The break between a purely descriptive geography and modern geography is traditionally situated in the 1870's. Perhaps it was prepared by the contacts established inside Europe between scientists. It seems that natural sciences, agronomy and forest science had leading roles in this process. On this subject, we will try to explore the official missions and the stay of portuguese students in Northern Europe. This way, we will be able to trace the contribution of the ideas of Bernardino de Barros Gomes, who contributed towards the development of geographic thought a long time before geography became a University institution.

    2015-01-01

    Full Text Available This work reexamines in the light of new data a proposal put forward in Martins (2011 concerning the historical development of clitic placement in Portuguese. Prima facie, this syntactic change follows a surprising path apparently involving a sudden reversal in the direction of change after the sixteenth century. It is argued in this paper that previous analyses, including that of the present author, fail to recognise the existence in sixteenth century and later Portuguese of two (social dialects as regards the position of clitic pronouns. A simplistic observation of textual sources masks the complexity of the linguistic situation in the historical period in question, creating an illusion of continuity between different objects. The present study uses the sixteenth century cookbook Livro de Cozinha de um Frade Português do Século XVI, edited by Anabela Leal de Barros (2013, as an especially valuable textual source to help us understand the history of clitic placement in Portuguese.

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

    Full Text Available This paper aims to discuss prefixes from a historical perspective, as well as to observe nuances of stylistic value in them. The choice of subject was basically due to two reasons: (i the considerations set out by Martins (2003 on the low stylistic productivity caused by prefixal derivation – especially if compared to suffixal derivation; and (ii the considerations set out by Silva (2009 on the so-called de-language, of negativity, in Manoel de Barros. At first we worked on a brief historically and etymologically-oriented incursion on prefixes; and then, subjecting the reflections we gathered to a punctual corpus by the author, we highlighted examples in which features of the morpho-stylistic nature that contribute to the singularity of his work, also linked to the aesthetics of the fragmentary and to the smallest beings, can be explored.

    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.

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

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

    Full Text Available Para finales de la segunda década del siglo xx, Bogotá tiene poco que mostrar. Está detenida en el tiempo, sumergida en una rutina en la que las lluvias casi siempre le ganan a los días de sol y el barro salpica todo, tanto a la gente elegante como a la gente sencilla, que visten lo mejor de sus prendas para presentarse en calles, almacenes y templos. La rutina menuda de hombres y mujeres y la rutina trascendente de políticos y escritores en diarios y revistas, fue sustituida, de repente, por la de la muerte. Nada similar para comparar tenían en su memoria esos bogotanos que en los meses de octubre y noviembre de 1918 tuvieron que vivir en su ciudad una pesadilla causada por una gripa que de igual modo hacía estragos en muchos otros lugares del mundo.

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

    Full Text Available In this study, which cuts and deepens a wider research (LUNKES, 2014, we will situate discursivities about work whose functioning strengthens the effects of evidence (PÊCHEUX, 2009 [1975] in the relations of senses that the subject establishes with work and with the need for medicament use. The work appears as one way in which the subject reaches appreciation in the capitalist social formation. According to Orlandi (2007, p. 15, this social formation of "heroic culture of the subject" works coercively and makes him responsible for the success or failure of his endeavors. That way, in addition to corroborate to a social frame of medicalization (BARROS, 2004, there are different directions in the production of meanings about depressive symptoms.

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

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

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

    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.

    Full Text Available While a clear consensus is emerging that predators can play a major role in shaping terrestrial communities, basic natural history observations and simple quantifications of predation rates in complex terrestrial systems are lacking. The potential indirect effect of a large predatory ant, Paraponera clavata Fabricius (Formicidae: Ponerinae, on herbivores was determined on rainforest trees at La Selva Biological Station in Costa Rica and Barro Colorado Island in Panama. Prey and other food brought back to nests by 75 colonies of P. clavata were quantified, taking into account temporal, seasonal, and microhabitat variation for both foraging activity and composition of foraging booty. The dispersion and density of ant colonies and combined density with the mean amounts of prey retrieval were used to calculate rates of predation per hectare in the two forests. In addition, herbivory was measured on trees containing P. clavata and on trees where the ants were not foraging. Colonies at La Selva brought back significantly more nectar plus prey than those at Barro Colorado Island, but foraging patterns were similar in the two forests. At both forests, the ants were more active at night, and there was no significant seasonal or colonial variation in consumption of nectar, composition of foraging booty, and overall activity of the colonies. At La Selva, trees containing P. clavata colonies had the same levels of folivory as nearest neighbor trees without P. clavata but had significantly lower folivory than randomly selected trees. Predation by this ant was high in both forests, despite its omnivorous diet. This insect predator is part of potentially important top-down controls in these wet and moist forests.

A passagem descrita acima de Manoel de Barros diz que “a importância de uma coisa há que ser medida pelo encantamento que a coisa produza em nós”; isto impulsiona a refletir não só sobre nossas importâncias, mas, também sobre a importância do outro. O que o outro, aquele que é conhecido e também o desconhecido, elege como importância em sua experiência de vida, e, se pudesse selecionar, cartografar alguns momentos, experiências íntimas ou coletivas, para compartilhar com o outro, para torná-las públicas, o que compartilharia? Assim, Cartografias Afetivas busca, a partir de uma proposição aberta, criar cartografias diversas, construindo coletivamente reflexões acerca do ser professor-artista-cartógrafo-etc. A proposta tem o intuito de potencializar afeto e provocar encontros e atravessamentos em redes na criação de cartografias, propondo outros modos de pensar a relação com a educação, com arte, com a vida e suas importâncias. Nessa relação, o professor-artista-cartógrafo-etc., na contemporaneidade, desenha seu percurso em constante conexão com o que acontece no espaço/arte/tempo/vida.

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

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

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.

    Full Text Available Los euglenoides son eucariotas unicelulares flagelados que habitan ambientes acuáticos y suelos de una gran diversidad de ecosistemas. Este trabajo presenta la descripción morfológica ultraestructural del euglenoide E. pailasensis aislado de las fuentes de lodo caliente de las "pailas de barro" en el Volcán Rincón de la Vieja, Guanacaste, Costa Rica. La temperatura de estos sitios puede variar entre 38 y 98° C y puede tener un pH entre 1 y 4. El estudio se realizó utilizando microscopia electrónica de barrido y transmisión. El euglenoide está constituido por una célula típica que puede medir de 30 a 45 µm de largo y 8-10 µm de ancho, con membrana externa, película, cloroplastos, mitocondrias, núcleo, pigmentos granulares y demás organelas citoplasmáticas de un eucarionte. Esta delimitado por una membrana continua y por una película compuesta de aproximadamente 40 - 90 mionemas que miden entre 0.8 y 1.0 µm de ancho, dispuestas helicoidalmente sobre la célula. Se observó 5 cloroplastos elongados por célula, de 1-2 µm de diámetro y 6-12 µm de largo, delimitados por tres membranas y localizados en la periferia celular. Este posee glóbulos osmiofílicos y un pirenoide penetrado por pocos tilacoides. El material nutritivo se almacena en gránulos de paramilón y las mitocondrias presentan las crestas en disposición radial hacia el interior del lumen. La zona de la ámpula se observó sin flagelo y se notó una red de fibrillas que envuelve el espécimen.

    The number of day care centers in Brazil has doubled over the last few years; with this increase has come a rise in the numbers of cases of communicable disease, particularly pneumonia (the main cause of child mortality in Brazil). A study by Dr. Walter V.C. da Fonseca states that a day care child is 5 times more likely to contact pneumonia. However, since the income earned by women in Brazil today is necessary to meet basic needs, children must be left at home with relatives or sent to day care. Most of the centers taking in children under 6 years of age are urban; they care for, on average, 125-200 children. These children are usually from low income families who live on the outskirts of cities; free day care is only provided to working mothers. There are 3 social factors involved: the greater number of single-parent families, more households supported solely by the mother, and an economic crisis that has hit the poor particularly hard. Financial and administrative responsibility for these centers varies. The centers provide meals, baths, rest, education (including some special education services), and health care (doctors, dentists, and nurses). Some accept abandoned children, who are cared for until they are adopted. However, new studies indicate that the centers represent the primary risk factor for respiratory illnesses and were, until recently, the principal causes of diarrhea and child mortality. An ongoing comparative study by da Fonseca is analyzing the incidence rates of respiratory and infectious diseases among 400 children attending a nursery in Fortaleza in comparison to those for 400 cared for at home by family. Doctor Aluiso Barros, in another study, is observing 1000 children in 40 nurseries in Campinas. For 8 weeks, data was collected on the health, socioeconomic situation, medical history, and family medical history of each child. The nurseries were examined and information was collected regarding the number of diseases reported each month, their

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.

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

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

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

    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 δ13C 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.

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.

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

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

    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 Estimates of genetic parameters are important to study characteristics that are to be included in a breeding program of a genetic group. The information of 594 weights from 211 lambs of a genetic group of naturalized Sul-mato-grossenses sheep belonging to Manoel de Barros Foundation and breeding at Centro Tecnologico de Ovinos from Anhanguera-Uniderp University was used. The estimation of variance components in unicaracter and bicaracter analysis were carried out through Bayesian inference. Estimates of heritability ranged from unicaracter analyses (0.22 to 0.47 and the bicaracter analyses (0.13 to 0.78. The maternal environmental permanent effect was higher in birth weight and average daily gain from birth to 50 days in 24.2% and 19.5%, respectively, in the observed variation. Estimates of heritability, maternal environmental permanent effect participation, phenotypic and genetic correlations indicate that selection for average daily gain from birth to 90 days would imply increases in weight at 50 days, weight at 90 days and average daily gain from 50 to 90 days of lambs with no significant increase in birth weight and average daily gain birth at 50 days.

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 The recent economic crisis brought about new challenges and disrupted the previous convergence process in R&D systems of EU member countries. The new developments in the configuration of the European Research Area require the use of adequate methods for measuring disparities between EU countries and monitoring of the convergence process. In this context, our paper aims to explore the new trends in R&D disparities among different groups of EU countries by means of a specific method for assessing the convergence/divergence process, namely the "sigma convergence" indicator introduced by Barro and Sala-i-Martin (1995. Considering the sizeable heterogeneity that exists within the EU-28 and candidate countries, we performed separate analyses on two groups of countries that are likely to be more homogenous: old and new EU member countries. Our main finding is a convergence trend for both EU-28 and candidate countries and old EU members over 2006-2013, while the new EU countries seem to diverge in terms of the research and development activity as captured by the Summary Innovation Index. The existence of a systematic trend of convergence / divergence was further tested based on both Augmented Dickey - Fuller (ADF and DF- GLS stationarity tests.

  13. Análise Semiótica do Conto Passeio Noturno I, de Rubem Fonseca

    Full Text Available Este trabalho apresenta a análise do conto Passeio Noturno I, de Rubens Fonseca, a partir do percurso gerativo do sentido, orientado pelos postulados da semiótica greimasiana. Para a semiótica, o discurso apresenta-se “como uma superposição de níveis de profundidade diferente, que se articulam segundo um percurso que vai do abstrato ao mais concreto” (BARROS, 2001. Assim, de acordo com a noção de percurso gerativo a análise do conto desenvolveu-se em três etapas: o nível das estruturas fundamentais, o nível das estruturas narrativas e o nível das estruturas discursivas. A temática que subjaz à estrutura do conto é uma crítica à violência presente na sociedade capitalista onde convivem as “vozes da cultura” e as “vozes da barbárie”.

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

  17. A combinatorial approach to angiosperm pollen morphology.

    2016-11-30

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

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

  1. Effusive silicic volcanism in the Paraná Magmatic Province, South Brazil: Physico-chemical conditions of storage and eruption and considerations on the rheological behavior during emplacement

    Expressive occurrences of effusive deposits were identified in silicic units from the Paraná Magmatic Province outcropping in a key area in south Brazil where three units with different compositions occur (Caxias do Sul dacites, CSd, Barros Cassal andesites to dacites, BCs, and Santa Maria rhyolites, SMr). Textural and chemical characteristics of phenocrysts, microphenocrysts and microlites suggest that crystallization started in a shallow magma chamber and continued during ascent to the surface. These magmas had an unique character (e.g., very high temperatures 1000 °C and low H2O contents 1-2 wt%), and formed several types of deposits that are clearly indicative of locally fed lava flows and had physical properties consistent with this mode of eruption (e.g., viscosities as low as 104.2 Pa·s at ca. 1000 °C for the CSd). The very low estimated H2O contents are a consequence of their petrogenesis (i.e., fractionation from tholeiitic basalts plus assimilation of crustal melts from water-poor granitic sources), and was probably a key factor influencing the non-explosive nature of these deposits. The comparatively higher viscosity calculated for the Santa Maria rhyolite (> 1-2 orders of magnitude greater than CSd) would make it a better candidate to generate expressive pyroclastic deposits, but this might be offset by its remarkably low H2O contents (≤ 1 wt%) and low discharge ratios.

    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.

For manipulating the corpora, the program WordSmith Tools (SCOTT, 2012 version 6.0 is used. To support this study, two comparable corpora in English and Portuguese were also built from articles published in both national and international journals in remote sensing. The results show that the collocations in Portuguese seem to be still in the process of conventionalization, as the translators made use of greater variation in their translational options, which can be a way to make the text clearer for the reader.

Objective: The objective of this study was to analyze the effectiveness of physical therapy treatment in women attending the Urogynecology service of Hospital and Maternity Leonor Mendes de Barros. METHOD: We retrospectively assessed 65 records of patients with diagnosis of urinary incontinence treated between November 2005 and November 2006. In order to have their data analyzed, patients were divided into two groups; group MF, which underwent medical treatment and physiotherapy, and group M, which had only medical treatment. In order to compare both groups' quantitative data, the analysis was performed in Statistica® software using Mann Whitney's non-parametric test. The analysis of association between the quantitative variables was performed through the Chi-Square test at 5% (p > 0.05 significance level. RESULTS: We observed that 60.6% of patients who underwent physical therapy treatment and medical treatment had the urinary incontinence symptoms decreased or completely cured, while 80% of women belonging to the medical treatmen only-group underwent surgery. CONCLUSION: Thus, we conclude that physical therapy is essential in treatment protocols of urinary incontinence outpatient clinics and to prevent surgery.

    Highlights: • Dynamic parametric interaction in daily dose prediction under uncertainty. • Importance of temporal dynamics associated with the dose. • Different dose experienced by different population cohorts as a function of time. • Relevance of uncertainty reduction in the input parameters shows temporal dynamism. -- Abstract: We study the time dependent interaction between hydrogeological and exposure parameters in daily dose predictions due to exposure of humans to groundwater contamination. Dose predictions are treated stochastically to account for an incomplete hydrogeological and geochemical field characterization, and an incomplete knowledge of the physiological response. We used a nested Monte Carlo framework to account for uncertainty and variability arising from both hydrogeological and exposure variables. Our interest is in the temporal dynamics of the total dose and their effects on parametric uncertainty reduction. We illustrate the approach to a HCH (lindane) pollution problem at the Ebro River, Spain. The temporal distribution of lindane in the river water can have a strong impact in the evaluation of risk. The total dose displays a non-linear effect on different population cohorts, indicating the need to account for population variability. We then expand the concept of Comparative Information Yield Curves developed earlier (see de Barros et al. [29]) to evaluate parametric uncertainty reduction under temporally variable exposure dose. Results show that the importance of parametric uncertainty reduction varies according to the temporal dynamics of the lindane plume. The approach could be used for any chemical to aid decision makers to better allocate resources towards reducing uncertainty.

    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.

    Changes in reproductive state or the environment may affect the sensitivity of the hypothalamic-pituitary-andrenal (HPA) axis. However, little is known about the dynamics of the resulting corticosteroid stress response, in particular in tropical mammals. In this study, we address the modulation of corticosterone release in response to different reproductive conditions and seasonality in 326 free-living common fruit-eating bats (Artibeus jamaicensis) on Barro Colorado Island in Panama during dry and wet seasons. We present strong evidence that stress sensitivity is primarily modulated by reproductive condition. In reproductively active females, corticosterone increases were more rapid and reached higher levels, but also decreased significantly faster than in inactive females. The corticosterone response was weaker in reproducing males than in females and delayed compared to non-reproductive males. Testes volume in reproductively active males was negatively correlated with corticosterone concentrations. Our findings suggest differentiated dynamics in the corticosterone stress response between sexes, potentially reflecting conflicting ecological demands. In females, a strong acute corticosterone response may represent high stress- and risk-sensitivity that facilitates escape and thus helps to protect reproduction. In males, suppression during reproductive activity could reflect lowered stress sensitivity to avoid chronically elevated corticosterone levels in times of frequent aggressive and therefore costly inter-male encounters.

    Robinson, W. D.

    2001-01-01

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

In this sense , our objective is to perform a journey through the poetic universe from the reading of the texts Exercício de ser criança (1999, by Manoel de Barros, and Um pequeno tratado de brinquedos para meninos quietos (2009, by Selma Maria Kuasne, associating the m to the paintings by Candido Portinari, ‘Boys flying kites’ (1932, ‘Children playing’ (1938 and ‘Boys playing’ (1955. Indeed, these pictures enable us to rethink how the representation and the constitution of childhood in art are conceived and to under stand them in the weaving of poetry and painting, as well as the act of playing, in a dialectical process.

    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.

    This study aims to assess the generation of carbon credits from projects under the clean development mechanism of small hydropower (SHP), based on studies of the evolution of installed capacity for these new developments over the next nine years. For this reason, two hypotheses and two scenarios were considered in order to better represent the reality of revenue generation over the years. The first hypothesis considers the development of small hydro power installed according to the Ten Year Plan for Expansion of Energy 2019. The second hypothesis considers the study of Tiago Filho, Barros e Silva (2009) about growth of installed capacity based on the gross national product (GNP). The simulation of revenues from carbon credits was done using the spreadsheet in Microsoft Excel for Michellis Jr (2010). The results showed that the forecast of growth of SHP performed based on GNP (hypothesis 1) is more conservative, thus leading to a lower potential of carbon credits, about 4.113.957 tCO{sub 2} avoided. Already the results of hypothesis 2 showed a total of 3.247.717 tCO{sub 2} avoided. (author)

    Full Text Available Este artigo tem como objetivo discutir o relato de vivências de humilhação e de sofrimento de trabalhadoras que participaram de um grupo terapêutico com histórias de adoecimento no trabalho. O estudo de caráter qualitativo propôs-se desenvolver encontros em grupo fundamentado na proposta de Barros (1997 na constituição de grupos terapêuticos como dispositivo analítico. A discussão fundamenta-se nos relatos de trabalhadoras com histórias de humilhação, constrangimento e sentimentos nutridos de ressentimento vivenciados no trabalho. A análise das histórias de vida no trabalho mostra que, no caso dessas trabalhadoras, as habilidades, a criatividade e a dedicação ao trabalho foram sendo obstruídas pelas situações desqualificantes da submissão à chefia e da falta de autonomia, situações que levaram a uma maior exposição aos riscos de adoecimento no trabalho. Com a capacidade produtiva limitada, a trabalhadora torna-se alvo frequente de situações de humilhação e constrangimento - compondo um quadro de assédio moral no trabalho.

    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)

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

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

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

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.

    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, ppoverty ratio (0.02426, prate (-0.05905, prate and total fertility rate (0.11755, pIndia. The Barro-regression estimate reveals that improvements in economic and demographic conditions such as growth in state income (β=0.35020, ppoverty (β=0.01867, pIndia than institutional deliveries (β=0.00305). The negative β-coefficient (β=-0.69578, pIndia. 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 Quality of public finances belongs to a key policy challenge as its improvement should lead to a long-term economic growth. The aim of the paper is to investigate if the key channels and tools used by the public finance (structure of revenue system, size of the government and composition of expenditure, level and sustainability of fiscal position affect economic growth in the Czech Republic in the period 1995-2013. The empirical model is based on the methodology of Barro and Sala-i-Martin (2003 and the model of Mankiw et al. (1992 which is adapted to the framework of this study. The results of dynamic regressions suggest that economic growth is affected by public finance variables only partly and traditional sources of economic growth (human capital or openness play bigger role. Provided evidence shows that total tax burden as well as the structure of revenue system (especially implicit tax rates on labour and consumption should be primarily used as tools for maintain macroeconomic objectives. On the contrary, changes in size and composition of expenditure, balance and debt report not statistically significant impact.

    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. Este trabalho teve como objetivos descrever e analisar as características químicas, físicas e morfológicas de Planossolos afetados por sódio usados em cerâmica artesanal e estabelecer, por meio de análise multivariada, comparações entre os horizontes pedogenéticos e as camadas

    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.

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

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

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

    Noting the paucity of studies of convergence in energy consumption across the US states, and the usefulness of a study that shares the spirit of the enormous research on convergence in energy-related variables in cross-country contexts, this paper explores convergence in per-capita energy consumption across the US states over the 44-year period 1970–2013. Several well-known parametric and non-parametric approaches are explored partly to shed light on the substantive question and partly to provide a comparative methodological perspective on these approaches. Several statements summarize the outcome of our explorations. First, the widely-used Barro-type regressions do not indicate beta-convergence during the entire period or any of several sub-periods. Second, lack of sigma-convergence is also noted in terms of standard deviation of logarithms and coefficient of variation which do not show a decline between 1970 and 2013, but show slight upward trends. Third, kernel density function plots indicate some flattening of the distribution which is consistent with the results from sigma-convergence scenario. Fourth, intra-distribution mobility (“gamma convergence”) in terms of an index of rank concordance suggests a slow decline in the index. Fifth, the general impression from several types of panel and time-series unit-root tests is that of non-stationarity of the series and thus the lack of stochastic convergence during the period. Sixth, therefore, the overall impression seems to be that of the lack of convergence across states in per-capita energy consumption. The present interstate inequality in per-capita energy consumption may, therefore, reflect variations in structural factors and might not be expected to diminish.

  14. Do abundance distributions and species aggregation correctly predict macroecological biodiversity patterns in tropical forests?

    2016-01-01

    Abstract Aim It has been recently suggested that different ‘unified theories of biodiversity and biogeography’ can be characterized by three common ‘minimal sufficient rules’: (1) species abundance distributions follow a hollow curve, (2) species show intraspecific aggregation, and (3) species are independently placed with respect to other species. Here, we translate these qualitative rules into a quantitative framework and assess if these minimal rules are indeed sufficient to predict multiple macroecological biodiversity patterns simultaneously. Location Tropical forest plots in Barro Colorado Island (BCI), Panama, and in Sinharaja, Sri Lanka. Methods We assess the predictive power of the three rules using dynamic and spatial simulation models in combination with census data from the two forest plots. We use two different versions of the model: (1) a neutral model and (2) an extended model that allowed for species differences in dispersal distances. In a first step we derive model parameterizations that correctly represent the three minimal rules (i.e. the model quantitatively matches the observed species abundance distribution and the distribution of intraspecific aggregation). In a second step we applied the parameterized models to predict four additional spatial biodiversity patterns. Results Species‐specific dispersal was needed to quantitatively fulfil the three minimal rules. The model with species‐specific dispersal correctly predicted the species–area relationship, but failed to predict the distance decay, the relationship between species abundances and aggregations, and the distribution of a spatial co‐occurrence index of all abundant species pairs. These results were consistent over the two forest plots. Main conclusions The three ‘minimal sufficient’ rules only provide an incomplete approximation of the stochastic spatial geometry of biodiversity in tropical forests. The assumption of independent interspecific placements is most

    Full Text Available Monitoring of changes in forest biomass requires accurate transfer functions between remote sensing-derived changes in canopy height (ΔH and the actual changes in aboveground biomass (ΔAGB. Different approaches can be used to accomplish this task: direct approaches link ΔH directly to ΔAGB, while indirect approaches are based on deriving AGB stock estimates for two points in time and calculating the difference. In some studies, direct approaches led to more accurate estimations, while, in others, indirect approaches led to more accurate estimations. It is unknown how each approach performs under different conditions and over the full range of possible changes. Here, we used a forest model (FORMIND to generate a large dataset (>28,000 ha of natural and disturbed forest stands over time. Remote sensing of forest height was simulated on these stands to derive canopy height models for each time step. Three approaches for estimating ΔAGB were compared: (i the direct approach; (ii the indirect approach and (iii an enhanced direct approach (dir+tex, using ΔH in combination with canopy texture. Total prediction accuracies of the three approaches measured as root mean squared errors (RMSE were RMSEdirect = 18.7 t ha−1, RMSEindirect = 12.6 t ha−1 and RMSEdir+tex = 12.4 t ha−1. Further analyses revealed height-dependent biases in the ΔAGB estimates of the direct approach, which did not occur with the other approaches. Finally, the three approaches were applied on radar-derived (TanDEM-X canopy height changes on Barro Colorado Island (Panama. The study demonstrates the potential of forest modeling for improving the interpretation of changes observed in remote sensing data and for comparing different methodologies.

  16. 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.

However, there is a lack of monitoring of community dynamics from the perspective of phylogeny. We attempted to understand temporal phylogenetic turnover in a 50 ha tropical forest (Barro Colorado Island, BCI) and a 20 ha subtropical forest (Dinghushan in southern China, DHS). To obtain temporal phylogenetic turnover under random conditions, two null models were used. The first shuffled names of species that are widely used in community phylogenetic analyses. The second simulated demographic processes with careful consideration on the variation in dispersal ability among species and the variations in mortality both among species and among size classes. With the two models, we tested the relationships between temporal phylogenetic turnover and phylogenetic similarity at different spatial scales in the two forests. Results were more consistent with previous findings using the second null model suggesting that the second null model is more appropriate for our purposes. With the second null model, a significantly positive relationship was detected between phylogenetic turnover and phylogenetic similarity in BCI at a 10 m×10 m scale, potentially indicating phylogenetic density dependence. This relationship in DHS was significantly negative at three of five spatial scales. This could indicate abiotic filtering processes for community assembly. Using variation partitioning, we found phylogenetic similarity contributed to variation in temporal phylogenetic turnover in the DHS plot but not in BCI plot. The mechanisms for community assembly in BCI and DHS vary from phylogenetic perspective. Only the second null model detected this difference indicating the importance of choosing a proper null model.

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

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

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

    Full Text Available Se considera como azulejo en sentido estricto a una pieza de barro vidriado de forma cuadrada o rectangular, destinada a revestimientos arquitectónicos. Es esta su finalidad principal aunque no la única sobre todo desde la implantación del azulejo plano pintado para cubrir amplias superficies como si se tratara de cuadros o tapices. Muy a menudo se forran con estas piezas cerámicas pavimentos, techos, envigados y cubiertas en exterior, pero van a ser los muros el espacio predilecto para chapar. Es justamente esta preferencia la que personaliza, por lo que al uso se refiere, al azulejo pintado peninsular frente a su homónimo italiano. Las características de la superficie recubierta van a incidir sobre la selección de motivos que se organizarán en grandes paneles murarlos desarrollados de manera continuada. La temática del azulejo que reviste paramentos gira en torno a lo que se denomina azulejos de composición en los que se representa un asunto o motivo puntual a cuyo realce contribuye el resto, o bien más frecuentemente, se opta por repetir un motivo contenido íntegramente en cada azulejo, que además posee parte de otro común con la contigua. Se logra así con el empleo de módulos repetitivos, hacer asociaciones en cualquier dirección, según las posibilidades del espacio disponible, de ahí el enorme éxito de la fórmula.

O ver a arquitetura pela visão da poesia reabre a possibilidade de, pela experiência estética e a ferramenta do imaginário, ser possível articular saberes, construir identidades e (reconfigurar a relação de distância entre o observador e o objeto da arte. Por intermédio da poesia nos deparamos com uma dimensão que é, antes de tudo, emotiva e sensível. Plena de afeto, a arquitetura, é sim, terreno poético. Tão indelével quanto a concretude e a materialidade do espaço físico e suas qualidades mensuráveis e físicas. O universo da poesia está disponível à leitura tanto quanto o da arquitetura. E essa releitura se reveste de importância quando consideramos a necessidade de, na contemporaneidade, colocarmo-nos como sujeitos na história, diante de uma produção artística em um mundo globalizado, mas não universal.

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.

    Ultramafic (UM) rocks are known to be nickel (Ni) rich and to weather quickly, which makes them a good candidate to look at the Ni isotope systematics during weathering processes at the Earth's surface. The present study aims at identifying the Ni solid speciation and discussing the weathering processes that produce Ni isotope fractionation in two deep laterite profiles under tropical conditions (Barro Alto, Goiás State, Brazil). While phyllosilicates and to a lower extent goethite are the main Ni-bearing phases in the saprolitic part of the profile, iron (Fe) oxides dominate the Ni budget in the lateritic unit. Nickel isotopic composition (δ60Ni values) has been measured in each unit of the regolith, i.e., rock, saprock, saprolite and laterite (n = 52). δ60Ni varies widely within the two laterite profiles, from -0.10 ± 0.05‰ to 1.43 ± 0.05‰, showing that significant Ni isotope fractionation occurs during the weathering of UM rocks. Overall, our results show that during weathering, the solid phase is depleted in heavy Ni isotopes due to the preferential sorption and incorporation of light Ni isotopes into Fe oxides; the same mechanisms likely apply to the incorporation of Ni into phyllosilicates (type 2:1). However, an isotopically heavy Ni pool is observed in the solid phase at the bottom of the saprolitic unit. This feature can be explained by two hypotheses that are not mutually exclusive: (i) a depletion in light Ni isotopes during the first stage of weathering due to the preferential dissolution of light Ni-containing minerals, and (ii) the sorption or incorporation of isotopically heavy Ni carried by percolating waters (groundwater samples have δ60Ni of 2.20 and 2.27‰), that were enriched in heavy Ni isotopes due to successive weathering processes in the overlying soil and laterite units.

    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

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

    Directory of Open Access Journals (Sweden)

    F Andrew Jones

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

    Full Text Available Este ensaio se origina do trabalho poético de Manoel de Barros, particularmente deste macro-texto que são as Memórias Inventadas – A Infância, trazendo como problema a relação, o mais das vezes conflituosa dos relatos de vida face aos gêneros literários. Observando-se a amplitude de formas de tradução da idade infantil, pelo filtro da sensibilidade artística, é perceptível que as memórias do escritor rarefazem a narração de relatos com lugar e tempo marcados, em favor da formulação de um pensamento acerca de um liame estreito entre a infância e a poesia. A equação infância = poesia decorre amplamente do fato de que o texto rememorativo aqui analisado representa um súmula poética do trabalho do escritor em função da recuperação de temas, personagens e hábitos de composição espalhados ao longo da obra e também uma configuração de sua poeisis, pois, sendo a poesia manoelina, esboçada nas memórias, de cunho auto-meditativo, tem-se como resultado, às vezes, um discurso, cuja matéria é a própria dicção poética.

    Full Text Available “Para encontrar o azul eu uso pássaros...” é uma chave ofertada pelo poeta Manoel de Barros para transver o mundo das materialidades e dos pensamentos. Num sobrevoo na paisagem amazônica rica em formas, cores e pensamentos míticos, podemos nos afetar numa vasta diversidade cultural e biológica. Essa paisagem é manejada pelos povos indígenas desde tempos imemoriais provando que é possível estabelecer relações com a floresta baseadas em práticas de baixo impacto e convivência com os outros seres que ali habitam. A Amazônia é o bioma com maior concentração de vidas co-habitando a mesma região, resultando em sistemas ecológicos e biogeográficos de alta complexidade. Atualmente, sofre grande pressão pelos modelos atuais de ocupação pautados pelo agronegócio que prioriza o capital econômico. É nesse cenário que a artista-bióloga Ruth Albernaz cria sua imagética para propor uma arte sensível que dialogue com a biodiversidade e com o contexto mitológico amazônico. Aqui apresentaremos imagens da série intitulada Voos Xamânicos, que esteve em exposição na Galeria do Sesc Arsenal, em Cuiabá, MT no período de 07 de novembro a 19 de dezembro de 2014, com curadoria da arte-educadora Imara Pizzato Quadros. O tema escolhido foi a palavra-alma “Xamã” por se tratar de um assunto que foi fonte e substrato dessa mostra que apresentou obras inéditas baseadas em pesquisas e experimentações realizadas desde 1996, no campo da Etnoecologia.

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

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

    The responses of tropical forests to global anthropogenic disturbances remain poorly understood. Above-ground woody biomass in some tropical forest plots has increased over the past several decades, potentially reflecting a widespread response to increased resource availability, for example, due to elevated atmospheric CO2 and/or nutrient deposition. However, previous studies of biomass dynamics have not accounted for natural patterns of disturbance and gap phase regeneration, making it difficult to quantify the importance of environmental changes. Using spatially explicit census data from large (50 ha) inventory plots, we investigated the influence of gap phase processes on the biomass dynamics of four ‘old-growth’ tropical forests (Barro Colorado Island (BCI), Panama; Pasoh and Lambir, Malaysia; and Huai Kha Khaeng (HKK), Thailand). We show that biomass increases were gradual and concentrated in earlier-phase forest patches, while biomass losses were generally of greater magnitude but concentrated in rarer later-phase patches. We then estimate the rate of biomass change at each site independent of gap phase dynamics using reduced major axis regressions and ANCOVA tests. Above-ground woody biomass increased significantly at Pasoh (+0.72% yr−1) and decreased at HKK (−0.56% yr−1) independent of changes in gap phase but remained stable at both BCI and Lambir. We conclude that gap phase processes play an important role in the biomass dynamics of tropical forests, and that quantifying the role of gap phase processes will help improve our understanding of the factors driving changes in forest biomass as well as their place in the global carbon budget.

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

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

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

    Although natural light sources produce depolarized light, patterns of partially linearly polarized light appear in the sky due to scattering from air molecules, dust, and aerosols. Many animals, including bees and ants, orient themselves to patterns of polarization that are present in daytime skies, when the intensity is high and skylight polarization is strong and predictable. The halicitid bee Megalopta genalis inhabits rainforests in Central America. Unlike typical bees, it forages before sunrise and after sunset, when light intensities under the forest canopy are very low, and must find its way to food sources and return to its nest in visually challenging circumstances. An important cue for the orientation could be patterns of polarization in the twilight sky. Therefore, we used a calibrated digital camera to image skylight polarization in an overhead patch of sky, 87.6° across, before dawn on Barro Colorado Island in Panama, where the bees are found. We simultaneously measured the spectral properties of polarized light in a cloudless patch of sky 15° across centered on the zenith. We also performed full-sky imaging of polarization before dawn and after dusk on Lizard Island in Australia, another tropical island. During twilight, celestial polarized light occurs in a wide band stretching perpendicular to the location of the hidden sun and reaching typical degrees of polarization near 80% at wavelengths >600 nm. This pattern appears about 45 minutes before local sunrise or disappears 45 minutes after local sunset (about 20 minutes after the onset of astronomical twilight at dawn, or before its end at dusk) and extends with little change through the entire twilight period. Such a strong and reliable orientation cue could be used for flight orientation by any animal with polarization sensitivity that navigates during twilight.

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

    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

Foot orthoses have been reported as an adjuvant intervention to improve balance by stimulating foot plantar mechanical receptors and thus increasing somatosensory input. Purpose: The aim of this study is to evaluate the effect of flat and textured insoles on the balance of primary care elderly people. Design: Prospective, parallel, randomized, and single-blind trial. Methods: A total of 100 subjects from a primary care unit, aged ≥65 years, were randomly assigned to intervention groups with flat insoles (n=33, textured insoles (n=33, or control group (n=34 without insoles. The Berg Balance Scale and the Timed Up and Go test were assessed at baseline and after 4 weeks. Results: Improvements in the Berg Balance Scale and the Timed Up and Go test were noted only in intervention groups with insoles but not in control group. No significant difference was found between flat and textured insoles. Minor adverse effects were noted only in the group with textured insoles. Conclusion: The results suggest that foot orthoses (both flat and textured insoles are effective in improving balance in primary care elderly people. They may represent a low-cost and high-availability adjuvant strategy to improve balance and prevent falls in this population. Keywords: balance, elderly, orthoses, insole

    Fifty years ago, Baker and Fedorov proposed that the high species diversity of tropical forests could arise from the combined effects of inbreeding and genetic drift leading to population differentiation and eventually to sympatric speciation. Decades of research, however have failed to support the Baker–Fedorov hypothesis (BFH), and it has now been discarded in favor of a paradigm where most trees are self-incompatible or strongly outcrossing, and where long-distance pollen dispersal prevents population drift. Here, we propose that several hyper-diverse genera of tropical herbs and shrubs, including Piper (>1,000 species), may provide an exception. Species in this genus often have aggregated, high-density populations with self-compatible breeding systems; characteristics which the BFH would predict lead to high local genetic differentiation. We test this prediction for five Piper species on Barro Colorado Island, Panama, using Amplified Fragment Length Polymorphism (AFLP) markers. All species showed strong genetic structure at both fine- and large-spatial scales. Over short distances (200–750 m) populations showed significant genetic differentiation (Fst 0.11–0.46, P < 0.05), with values of spatial genetic structure that exceed those reported for other tropical tree species (Sp = 0.03–0.136). This genetic structure probably results from the combined effects of limited seed and pollen dispersal, clonal spread, and selfing. These processes are likely to have facilitated the diversification of populations in response to local natural selection or genetic drift and may explain the remarkable diversity of this rich genus.

    A survey was carried out in Ribeirão Preto, S. Paulo State, Brazil, between June 1978 and May 1979 with a view to studying the prevalence of low birth weight and its occurrence among different social classes. Data were collected from 8,878 singleton live births in eight maternity hospitals, accounting for 98% of all births in the area. Social classes were determinated by the use of a model proposed by Singer and modified for epidemiological purposes by Barros. Out of the 8,878 births, 660 (7.5%) were of low birth weight. The prevalence of deficient weight at birth (between 2,500 and 2,999 grams) was of 21.1%. Analysis indicated that 50.6% of children with low birth weight were at term and the majority of them suffered form intrauterine growth retardation. The prevalence of low birth weight according to social class was seen to be lower in the bourgeoisie classes (ranging from 2.8% to 3.9%) and higher in working classes (from 7% up to 9.5%). Low birth weight (defined as less than or equal to 2,500 grams) was used for purposes of comparison with other previous surveys. The percentage was lower in this study (8.3%) than that found in the Interamerican Investigation of Mortality in Childhood (8.7%), carried out in 1968-70. No statistically significant differences in the percentage of low birth weight were found in the case of Ribeirão Preto when these two surveys were compared.

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

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

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

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

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

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

    The formation of canopy gaps is fundamental for shaping forest structure and is an important component of ecosystem function. Recent time-series of airborne LIDAR have shown great promise for improving understanding of the spatial distribution and size of forest gaps. However, such work typically looks at gap formation across multiple years and important intra-annual variation in gap dynamics remains unknown. Here we present findings on the intra-annual dynamics of canopy gap formation within the 50 ha forest dynamics plot of Barro Colorado Island (BCI), Panama based on unmanned aerial vehicle (UAV) remote sensing. High-resolution imagery (7 cm GSD) over the 50 ha plot was obtained regularly (≈ every 10 days) beginning October 2014 using a UAV equipped with a point and shoot camera. Imagery was processed into three-dimensional (3D) digital surface models (DSMs) using automated computer vision structure from motion / photogrammetric methods. New gaps that formed between each UAV flight were identified by subtracting DSMs between each interval and identifying areas of large deviation. A total of 48 new gaps were detected from 2014-10-02 to 2015-07-23, with sizes ranging from less than 20 m2 to greater than 350 m2. The creation of new gaps was also evaluated across wet and dry seasons with 4.5 new gaps detected per month in the dry season (Jan. - May) and 5.2 per month outside the dry season (Oct. - Jan. & May - July). The incidence of gap formation was positively correlated with ground-surveyed liana stem density (R2 = 0.77, p < 0.001) at the 1 hectare scale. Further research will consider the role of climate in predicting gap formation frequency as well as site history and other edaphic factors. Future satellite missions capable of observing vegetation structure at greater extents and frequencies than airborne observations will be greatly enhanced by the high spatial and temporal resolution bridging scale made possible by UAV remote sensing.

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

    Full Text Available The problem in an adequate assessment of the level of competition in the banking market has prompted researchers to search constantly some new methods. The most famous of them were later successfully adapted to the banking market, are a models of Bresnahan, Panzar-Rosse, Bertrand, Iwat, Monti-Klein-Modesto Barros and others. In Ukraine, the process of assessing the level of competition in the banking sector is very relevant, in line with the recent reforms of particular relevance and distribution. Regarding the domestic deposit market, there is a shortage of qualitative analysis of this issue, unlike foreign practice. Therefore this study we try to solve this problem. The key goal of researchers in this study is in a detailed analysis to identify the important factors which make influence on the allocated markets, in particular on lending and deposit rates. Based on these factors there could be implemented internal adjustment processes taking place in the markets. The purpose of the article is to determine the level of competition in the deposit market of Ukraine in 2006-2015 basing on nonstructural Panzar- Rosse model and identify key factors that affect this level. Methodology. To research the level of competition in the deposit market of Ukraine the Panzar-Rosse model was used, in which separate 11 models were built using the integrated tool “Multiple regression” in the software package of statistics analysis STATISTICA. The input data in the model was presented with the information on financial performance of Ukrainian banks during ten years from 01.01.2005 till 01.01.2015. Results of this research showed that in Ukrainian deposit market there is a monopolistic competition, as proved by the calculated values of H-statistics index. The year of 2008, in the context of the global economic crisis, was marked as an unbalanced period for deposit market of Ukraine. Practical implications.

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

    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.

    Abundance patterns during 6-7 years and orchid visitation were determined for 51 species of the 57 local euglossine bees. Male bees were counted at 3 chemical attractants presented in the same manner each month. Sites were separated by 75 km but included wet Atlantic forest at 500 m elevation, moist forest at 180 m near Barro Colorado Island, and cloud forest at 900 m near the Pacific ocean. 1. From 15 to 30 euglossine species of 4 genera were active in each month and site; monthly species number and general bee abundance were positively correlated. Many species had 3 annual abundance peaks (range 1-4) and were active throughout the year, but peak annual abundances rarely occurred during late wet or early dry seasons. In contrast, Eufriesea generally were present as adults only 1-2 months in a year. 2. Euglossine populations were exceptionally stable. Species at each site were more stable than any known insect population, and stability and abundance were positively associated. However, year-to-year population stability and the degree of seasonality were not correlated. Among the three sites, the more diverse (species rich) bee assemblages displayed lower stability; these were the wetter and upland sites. 3. The most abundant bees visited more orchid species. Eg. and El. each visited and average of 4 orchid species (range 0-13); Ex. and Ef. visited 0-3. Stable populations did not visit more or fewer orchid species than did unstable populations. 4. Less than 68% of species at each site visited orchid flowers; less than a few dozen of the 100-800 bees counted in a day carried orchid pollinaria. Over 20% of the euglossine species never were seen with pollinaria at any site and probably seldom visit orchids in central Panama. 5. Most bee species visited 1 or no fragrance orchids in a given habitat. Orchids tended to utilize common pollinators that seldom included more than 1 species, and they utilized stable or unstable, seasonal or aseasonal bees. However, the most

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

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

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

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.

    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

    The Tonian Goiás Stratiform Complex (TGSC, Goiás, central Brazil), is one of the largest mafic-ultramafic layered complexes in the world, emplaced during the geotectonic events that led to the Gondwana accretion. In this study, we present trace elements and in-situ U/Pb-Lu-Hf analyses of zircons and 87Sr/86Sr ratios of plagioclases from anorthosites and gabbros of the TGSC. Although formed by three isolated bodies (Cana Brava, Niquelândia and Barro Alto), and characterized by a Lower and Upper Sequence (LS and US), our new U/Pb zircon data confirm recent geochemical, geochronological, and structural evidences that the TGSC has originated from a single intrusive body in the Neoproterozoic. New Hf and Sr isotope ratios construe a complex contamination history for the TGSC, with different geochemical signatures in the two sequences. The low Hf and high Sr isotope ratios of the Lower Sequence (εHf(t) from -4.2 down to -27.5; 87Sr/86Sr = 0.706605-0.729226), suggest the presence of a crustal component and are consistent with contamination from meta-pelitic and calc-silicate rocks found as xenoliths within the Sequence. The more radiogenic Hf isotope ratios and low Sr isotope composition of the Upper Sequence (εHf(t) from 11.3 down to -8.4; 87Sr/86Sr = 0.702368-0.702452), suggest a contamination from mantle-derived metabasalts in agreement with the occurrences of amphibolite xenoliths in the US stratigraphy. The differential contamination of the two sequences is explained by the intrusion of the TGSC in a stratified crust dominated by metasedimentary rocks in its deeper part and metavolcanics at shallower levels. Moreover, the differential thermal gradient in the two crystallizing sequences might have contributed to the preservation and recrystallization of inherited zircon grains in the US and total dissolution or magmatic overgrowth of the LS zircons via melt/rock reaction processes.

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

Blood samples were collected from 113 dogs and 85.7% (30/35 of the serologically positive dogs had their blood re-collected after three months. The diagnosis of T. cruzi infection was performed by: fresh blood examination, hemoconcentration, hemoculture, as well as the serological assays Indirect Immunofluorescence Essay (IFAT and Imunoenzimatic essay (ELISA. The presence of positive dogs in both serologic tests (IFAT + ELISA was 31% (35/113, distributed among the four communities as follows: (12/44 Uricuriteua, (19/40 Cezaréia, (1/16 Aliança and (3/13 Catita. None of the samples was positive in the fresh blood examination or hemoconcentration, although it was possible to isolate T. cruzi, DTU TcI in one dog sample during its blood re-collection. These results show how dogs are exposed to the T. cruzi transmission cycle, revealing their importance as sentinels for the presence of this parasite in the studied area.

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.

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

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

    Phenology is a critical driver of ecosystem processes. There is strong evidence that phenology is shifting in temperate ecosystems in response to climate change, but tropical tree and liana phenology remains poorly quantified and understood. A key challenge is that tropical forests contain hundreds of plant species with a wide variety of phenological patterns. Satellite-based observations, an important source of phenology data in northern latitudes, are hindered by frequent cloud cover in the tropics. To quantify phenology over a large number of individuals and species, we collected bi-weekly images from unmanned aerial vehicles (UAVs) in the well-studied 50-ha forest inventory plot on Barro Colorado Island, Panama. Between October 2014 and December 2015 and again in May 2015, we collected a total of 35 sets of UAV images, each with continuous coverage of the 50-ha plot, where every tree ≥ 1 cm DBH is mapped. Spectral, texture, and image information was extracted from the UAV images for individual tree crowns, which was then used as inputs for a machine learning algorithm to predict percent leaf and branch cover. We obtained the species identities of 2000 crowns in the images via field mapping. The objectives of this study are to (1) determined if machine learning algorithms, applied to UAV images, can effectively quantify changes in leaf cover, which we term "deciduousness; (2) determine how liana cover effects deciduousness and (3) test how well UAV-derived deciduousness patterns match satellite-derived temporal patterns. Machine learning algorithms trained on a variety of image parameters could effectively determine leaf cover, despite variation in lighting and viewing angles. Crowns with higher liana cover have less overall deciduousness (tree + liana together) than crowns with lower liana cover. Individual crown deciduousness, summed over all crowns measured in the 50-ha plot, showed a similar seasonal pattern as MODIS EVI composited over 10 years. However

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

    Full Text Available 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.

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

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

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

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

    (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.

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 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

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.

    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 The rain which took place between November 1996 and January 1997 caused a landslide in the surrounding area of the village of Cava, placed in the basin of the river Segre (Catalan Prepyrenees. The litology and structure of the mobilized materials, and the agrarian works and its further abandonment, as well, have been fundamental features causing the aforementioned erosive process. The study of this phenomena has highlighted the existence of two different parts: a rotational movement in a hillside's sector and a mud flow. The analysis of the space-time cause's of these processes, its inter-relation with similar ones, and its influence on the human activities, constitute an essential feature in order to define planification and prevention strategies.

    [es] Las precipitaciones acaecidas entre noviembre de 1996 y enero de 1997 dieron lugar a un deslizamiento de tierras en las inmediaciones del pueblo de Cava, situado en la cuenca del río Segre (Prepirineo Catalán. La litología y la estructura de los materiales movilizados, así como las prácticas de conservación agrícola y su posterior abandono, han sido fundamentales en el desencadenamiento de este proceso erosivo. El estudio del fenómeno ha puesto de relieve dos partes diferenciadas: un movimiento rotacional en un sector de la ladera y una colada de barro originada por los materiales acumulados en la cabecera del torrente por el cual discurrió posteriormente. El análisis de las causas espacio-temporales de estos procesos y su interrelación con otros parecidos, así como la incidencia en las actividades humanas, son un factor esencial para definir estrategias de planificación y prevención.

Epub 2010 December 01.En este trabajo se estudia la biología de la nidificación de cuatro especies de Trypoxylon (Trypargilum recolectadas a partir de 91 nidos-trampa en el Bosque Chaqueño Serrano de Córdoba, Argentina. La arquitectura de los nidos fue similar para las cuatro especies: celdas de cría ubicadas linealmente, una detrás de la otra separadas por tabiques de barro, como es habitual en otras especies del subgénero Trypargilum. El 48% de los nidos presentó celda vestibular, mientras que sólo dos nidos presentaron celdas intercalares. El ancho de los tabiques y el largo de las celdas de cría difirió entre las especies y estuvo relacionado con el tamaño de las avispas que emergieron. Así mismo, el diámetro del nido-trampa estuvo directamente relacionado con el tamaño corporal promedio de las especies de mayor y menor tamaño. La mortalidad debida a parasitoides (Eulophidae; Melittobia sp. fue similar para las cuatro especies, mientras que la causada por cleptoparásitos (Chrysididae fue mayor en T. lactitarse. No fue posible relacionar la presencia de celda vestibular con la mortalidad debida a enemigos naturales para ninguna de las especies. La familia de arañas más frecuentemente utilizada como presa fue Araneidae.

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

El color en los interiores ha sido estudiado para dar la impresión de frescura; en el exterior sólo se han pintado las zonas que podían reflejar molestamente los rayos solares.

    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

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

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

    . Simulations are also performed using the Advanced Weather and Research Forecasting (WRF-ARW) for moist zonal flow over Gaussian ridge, and the energy spectra close and away from the ground are studied. 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).

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.

These values are batter than a brick wall of 0.20 m thick with a finish plaster on both sides of the wall, whose value is 4.13 W/m2K. For impact resistance, panels were constructed and tested to soft shock, on 1:1 scale. The permanent deformation in all cases was less than 3.6 mm required by the current standard. This implies that there was no appreciable deformations suffered enclosures providing security to a home.

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

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.

    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 site of Chos Malal is located on the north of the Province of Neuquen (Argentina).Cordillera del Viento is a mountain located 30 km northward, it is 90 km long, with average heights of 2800 m and with intense winds.This region has the adequate characteristics to be one of the best zones of the Norpatagonia for the exploitation of wind resources.Nevertheless, the existing wind speed data of the place is disconcerting.The biggest amount of information proceeds from the old weather station of the 'Secretaria de Agricultura y Ganaderia de la Nacion Argentina' Office and from the National Weather Service 'Servicio Meteorologico Nacional de Argentina' (SMN). Results from this data (1941-1960 period) shows that the mean annual wind speed is only 2.8 m/s.This value is conservative, probably due to the method employed on the measurement, which consisted of the estimation through the Beaufort scale, or the over-estimation error of the calms, as the one detected by Barros for the South of Patagonia.Due to this discordance, it was decided to evaluate the resource with modern instrumental. Afterwards, automatic weather stations were installed (Davis model Monitor II and Wizard) at the airport of Chos Malal (S 37 26 49 ; W 70 13 53 ; 852 m msl) with sensors at 2.5m, 10m and 18m above ground level.With this data (period 2000-2004) this study was oriented to characterize some aspects of the atmospheric boundary layer, the air turbulence and the relation between average wind speed and gusts.The annual average velocity (2000-2004) was 3.78 m/s, 35% greater than meteorological statistics from SMN (1941-1950 and 1951-1960 decades). The maximum velocity was 7.35 m/s, almost twice the average wind speed. With the measured data at 10 m, the Weibull distribution was calculated, using the form factor K = 1.2; and the scale factor C = 3.95. Also the wind rose was calculated, where the maximum frequency was produced at WNW.During 5 days of November of 2001, simultaneous observations at 2

    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.

    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.

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

    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.

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.

Although 6-PBRT has been validated in stable patients, the possibility of a high floor effect could compromise the validity of the test in the hospital setting. The aim of this study was to verify the convergent validity of 6-PBRT in hospitalized patients with acute exacerbation of COPD (AECOPD. Methods: A cross-sectional study was conducted in a tertiary hospital. Patients who were hospitalized due to AECOPD and healthy elderly participants, voluntarily recruited from the community, were considered for inclusion. All participants underwent a 6-PBRT. Isokinetic evaluation to measure the strength and endurance of elbow flexors and extensors, handgrip strength (HGS, spirometry testing, the modified Pulmonary Functional Status Dyspnea Questionnaire (PFSDQ-M, the COPD assessment test (CAT, and symptoms of dyspnea and fatigue were all measured as comparisons for convergent validity.

    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

    . Comme on considere cette operation comme une mesure provisoire, on s'occupe activement de mettre au point une methode permettant de reduire la mobilite des matieres stockees, afin d'etre plus certain de leur confinement a long terme. Dans les reservoirs souterrains existants, on fera evaporer, jusqu'a obtention de tourteaux de sel, les volumes importants de dechets et de gainage, qui, par nature, sont peu susceptibles d'auto-echauffement. Les etudes en laboratoire et les premiers essais effectues avec un reservoir de 5000 gallons montrent que le passage d'un courant d'air chaud a travers la solution, associe a une carbonatation controlee pour transformer Thydroxyde de sodium libre en carbonate de sodium, permet d'eliminer suffisamment d'eau pour former un tourteau de sel non hygroscopique. Les dechets susceptibles d'auto-echauffement seront fractionnes pour permettre d'entreposer separement les emetteurs de chaleur a longue periode dans de petits recipients tres resistants. Etant donne que ces matieres peuvent etre utilisees avec profit, on pourrait en obtenir sur demande. Apres 5 a 10 ans de desintegration des emetteurs de chaleur a courte periode, les dechets salins residuels seront combiries avec les dechets courants de degainage pour evaporation comme il est dit plus haut. Pour pouvoir mener a bien le traitement chimique necessaire, on amenage un ancien batiment a cellules isolees. On recourra probablement a l'extraction par solvant (D2EHPA) pour separer le strontium et le cerium des dechets acides, mais on n'a pas encore decide si la separation du cesium se fera au moyen de l'extraction par solvant, par echanges d'ions ou par precipitation. On prevoit que l'ensemble de l'operation pourra etre realise aux environs de 1966.

    , gated community that has no public access.The map area has a long history of petroleum exploration and development. Several offshore gas fields were discovered and were developed by onshore directional drilling in the 1950s and 1960s. Three offshore petroleum platforms were installed in adjacent federal waters in 1976 (platform “Honda”) and 1989 (platforms “Heritage” and “Harmony”). Local offshore and onshore operations were serviced for more than a century by the Gaviota marine terminal, which is currently being decommissioned and will be abandoned in an intended transition to public open space. The Offshore of Gaviota map area lies within the western Santa Barbara Channel region of the Southern California Bight, and it is somewhat protected from large Pacific swells from the north and northwest by Point Conception and from south and southwest swells by offshore islands and banks. Much of the shoreline in the map area is characterized by narrow beaches that have thin sediment cover, backed by low (10- to 20-m-high) cliffs that are capped by a narrow coastal terrace. Beaches are subject to wave erosion during winter storms, followed by gradual sediment recovery or accretion in the late spring, summer, and fall months during the gentler wave climate.The map area lies in the western-central part of the Santa Barbara littoral cell, which is characterized by west-to-east transport of sediment from Point Arguello on the northwest to Hueneme and Mugu Canyons on the southeast. Sediment supply to the western and central part of the littoral cell is mainly from relatively small coastal watersheds. In the map area, sediment sources include Cañada de la Gaviota (52 km2), as well as Cañada de la Llegua, Arroyo el Bulito, Cañada de Santa Anita, Cañada de Alegria, Cañada del Agua Caliente, Cañada del Barro, Cañada del Leon, Cañada San Onofre, and many others. Coastal-watershed discharge and sediment load are highly variable, characterized by brief large events

    Los análisis preliminares indican un porcentaje de homología cercano al 97% entre las cepas analizadas, lo cual refleja la estabilidad genética del virus a través del tiempo, y nos permite pensar que los brotes recientemente ocurridos obedecen al incremento de la actividad selvática del virus, con el humano como huésped accidental al intervenir con su ecosistema, más que a la reintroducción de nuevas cepas de mayor virulencia (9-12.

    Full Text Available O conhecimento indígena sobre a pedodiversidade é o objeto principal da etnopedologia. Nesse sentido, a tradição agrícola e cultural dos índios Uapixana, do tronco lingüístico Aruaque, em Roraima, constitui relevante acervo imaterial de valor etnocientífico, sendo valorizada pela Universidade Federal de Roraima em seus cursos superiores de Educação Indígena no Estado. Neste trabalho confrontou-se a experiência etnopedológica dos índios Uapixana com o Sistema Brasileiro de Classificação de Solos, durante o levantamento de solos da Terra Indígena (TI Malacacheta. O sistema de classificação etnopedológica existente na comunidade indígena Uapixana da TI Malacacheta identifica e separa todos os principais compartimentos ambientais de ocorrência na área, permitindo relacionar aspectos de simples percepção e identificação (cor, textura, profundidade, vegetação com aspectos cognoscíveis (uso, tipo de cultivo, vocação, etc.. Os índios Uapixana identificam e classificam oito tipos básicos de solos, que ocorrem individualmente ou formando associações: Imii Wyzda'u (Terra Amarelada, Imii Wyza'u (Terra Vermelha, Imii Pudiidiu (Terra Preta, Imii Pudiidiza'u (Terra Roxa, Katy Bara Pudiidiu (Barro Arenoso, Imii Kaxidia'u (Estopa Preta, Imii Katy Bara Pudiidiu Naik Baraka'u (Terra Arenosa Preta e Branca e Imii Wyzadaza'u Rik Pudiidiu (Miscelânea de Terra Amarela, Roxa e afloramentos de rocha, abordando características morfológicas, físicas e químicas e as principais limitações quanto ao uso agrícola. Há relação evidente entre a dimensão do saber etnopedológico o saber etnoecológico, em sentido amplo. A experiência etnopedológica representa, assim, a extensão de uma abrangente cadeia de inter-relações homem-meio, dentro do princípio universal da ecologia humana da paisagem. O diálogo etnopedológico travado entre a comunidade indígena e os pedólogos trouxe contribuições muito relevantes e mutuamente

    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.

    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.

Os resultados obtidos indicam que durante o pré-último máximo glacial (cerca de 31.000 - 27.000 anos 14C AP e o ultimo máximo glacial (cerca de 27.000 - 13.000? anos 14C AP, a vegetação encontrada na região de estudo era composta de um mosaico floresta/savana, com a flora arbórea apresentando elementos de floresta temperada e
