    Full Text Available Wood borer species of the families Euplatypodidae and Scolytidae were observed attacking trees of Pinus sp. in the Municipality of Ribas do Rio Pardo, state of Mato Grosso do Sul, Brazil, in March 2000. This plantation had been previously burned in an accidental fire in January 2000, causing the trees to become partially or totally unhealthy, rendering them more susceptible to attack of these pests. Galleries of these wood borers were opened with a chisel to observe parameters such as their direction and form of these galleries. Species observed as wood borers of Pinus sp. were Euplatypus parallelus, Euplatypus sp. (Coleoptera: Euplatypodidae and Xyleborus affinis (Coleoptera: Scolytidae.

    Full Text Available O queijo de coalho artesanal é produto de origem animal muito consumido principalmente na região Nordeste do Brasil. É comumente fabricado com leite cru, não pasteurizado, como matéria prima, sem a utilização de boas práticas higiênicas, podendo veicular micro-organismos patogênicos ao consumidor. Assim, objetivou-se avaliar a presença de Salmonella sp. e quantificar Staphyloccocus aureus em queijos de coalho produzidos artesanalmente no município de São Rafael Rio Grande do Norte.Foram realizadas coletas em triplicata em sete queijarias artesanais do município, e, em seguida, os queijos foram transportados imediatamente em caixas isotérmicas, ao Laborátório de Biotecnologia Industrial da Universidade Federal Rural do Semi-Árido, onde foram submetidos à análise microbiológica de forma asséptica, conforme metodologia recomendada pela Instrução Normativa nº 62, de 26 de agosto de 2003, do Ministério da Agricultura, Pecuária e Abastecimento. Todas as amostras apresentaram elevadas contagens de Staphylococcus aureus, estando em desconformidade com o padrão exigido pela legislação brasileira para este grupo microbiano. Foi constatado ausência de Salmonella sp. nas amostras avaliadas. As análises microbiológicas evidenciaram péssimas condições de higiene de todos os queijos estudados, já que os mesmos apresentaram grande contaminação por Staphylococcus aureus, o que pode representar riscos à saúde pública.

    Full Text Available O objetivo do trabalho foi comparar a dinâmica, a ocorrência, a morfometria de oocistos e os períodos patentes de Cryptosporidium sp. em aves domésticas, patos (Anas platyrhynchos, pintos (Gallus gallus e codornas (Coturnix japonica, naturalmente infectadas, provenientes de dois mercados municipais do Estado do Rio de Janeiro, Rio de Janeiro (RJ. Houve diferenças quanto à ocorrência da infecção entre os dois locais e entre pintos e patos, mas não entre codornas. Para a morfometria, foram observadas diferenças estatísticas nas medidas dos diâmetros maior e menor e para o índice morfométrico calculado (P0,05. Na comparação do período de eliminação, patos tiveram um maior período com maiores quantidades de oocistos eliminados. Codornas e pintos apresentaram dinâmica de eliminação semelhante e não houve diferença quanto à concentração de oocistos. Pintos foram mais susceptíveis à infecção seguidos por patos e codornas. Pode-se concluir que a infecção natural por Cryptoporidium sp. foi frequente nas aves estudadas. Patos, pintos e codornas podem ser disseminadores do protozoário em mercados municipais do Rio de Janeiro, RJ. Assim, podem constituir risco de infecção.The objective of the current study was comparing the dynamic and occurrence of Cryptosporidium sp., as well as the morphometry and elimination period of oocysts in naturally infected ducks (Anas platyrhynchos, chickens (Gallus gallus and Japanese quails (Coturnix japonica from two local markets of Rio de Janeiro, RJ. There were significant differences considering the occurrence of infection between the two markets, and also between chickens and ducks, but not among Japanese quails. Also, significant statistical differences were observed in morphometry, considering the major and minor diameters of oocysts and the calculated morphometric index (P0.05. According to the elimination period, ducks eliminated oocysts for a longer period and in a higher number

    Full Text Available As primeiras populações foram fixadas próximas aos rios e com o crescimento destas e acréscimo de áreas impermeabilizadas, houve a supressão das áreas de várzea, alteração da dinâmica dos cursos d’água e, por conseguinte, ocorrência de inundações. Assim, este trabalho tem como objetivo verificar a interferência do uso da terra nas inundações na área urbana da bacia hidrográfica do Córrego da Servidão, Rio Claro (SP, em diferentes cenários, ou seja, sem canalização deste córrego (1958, em cenário em que o córrego foi canalizado (1972 e no cenário atual (2006. Os resultados indicaram que o aumento da impermeabilização, pelo crescimento da cidade de Rio Claro, foi o responsável pelos primeiros eventos de inundação do município. O poder público vem realizando algumas obras de engenharia e transferindo grande parte dos problemas relacionados com as inundações para áreas a jusante, onde hoje as inundações ocorrem.

    Full Text Available Within the scope of the MAR-14 Project, part of the Brazil-Germany Bilateral Agreement in Marine Sciences, an oceanographic survey aboard the R/V Victor Hensen was carried out in Brazilian coastal waters between Santos (23º56'S and Rio de Janeiro (22º54'S, from January 15 to January 22,1991. In this article we report results of preliminary analyses of the hydrographic data collected with CTD, STD, Nansen bottles and XBT's. These preliminary results show intense stratification in the first 200 m depth, and the penetration of the Brazil Current deep into the continental shelf region. Two eddy-like features were detected. The first one, anticyclonic, was located in the northern part of the domain and confined to the uppermost 200 m. The second, a cyclonic vortex, was found a little to the southwest below 200 m and extending downwards to about 800 m depth. Water mass analyses based on T-S diagrams suggest that the interface between the South Atlantic Central Water (SACW and the Antarctic Intermediate Water (AIW is located at about 500 m depth. One important aspect of this study is that this was the first time a high resolution survey with a CTD probe was realized along the eastern Brasilian Coast, south of Cabo Frio.Como parte do projeto MAR-14, componente do Acordo Bilateral Brasil-Alemanha em Ciências Marinhas, uma campanha oceanógrafica a bordo do R/V Victor Hensen foi realizada em águas costeiras do Brasil entre Santos (23º56'S, de 15 a 22 de janeiro de 991. Neste artigo reportamos resultados de análises preliminares dos dados hidrográficos coletados com o auxílio de CTD, STD, garrafas de Nansen e XBT's. Esses resultados preliminares mostram uma intensa estratificação nos primeiros 200 m de profundidade, e a penetração da corrente bem adentro da região sobre a plataforma continental.

    Full Text Available Este estudo teve por objetivo realizar o inventário arbóreo-urbano em 24 bairros do Município de Salto de Pirapora, SP, por meio da avaliação quali-quantitativa. Para tanto, foram obtidas informações relacionadas à: espécie arbórea, situação da copa e do tronco, orientação do tronco, fitossanidade, interceptação das raízes no passeio, necessidade de tratos silviculturais, altura total e altura da primeira bifurcação, assim como características do espaço viário. Foram registrados 868 indivíduos, dos quais 679 foram catalogados em 71 espécies arbóreas. A espécie de maior frequência foi Caesalpinia pluviosa, representando 13,6% do total, seguida de Ficus benjamin (10,4%, Lagerstroemia indica (5,0% e Terminalia catappa (4,8%. Quanto à condição do tronco, 68,8% dos indivíduos arbóreos não apresentaram problemas; 85,7% das árvores observadas possuíam orientação simpodial adequada; poucas árvores apresentavam danos relacionados à fitossanidade que poderiam interferir em sua integridade e, ou, longevidade; 69,6% não interferiam, de forma direta, na calçada; 32,8% das árvores necessitavam de podas por estarem acima da fiação elétrica; 0,5% necessitava de substituição; e 5,7% precisavam ser removidas. Com relação à altura total das árvores, 63,0% apresentavam crescimento menor que 5 m; e 65,3% com altura da primeira bifurcação do tronco inferior a 1,80 m. O Bairro Primavera destacou-se pelo maior número de árvores em sua urbanização. Em contrapartida, o Jardim Amélia apresentou apenas um indivíduo. Dessa forma, observou-se que cada bairro possuía sua particularidade, e ações de manutenção e enriquecimento, tanto relacionadas ao número de espécies quanto à quantidade de indivíduos, deveriam ser consideradas no planejamento urbano-arbóreo daquele município.

    This work aimed to assessing Strongyluris sp. cysts distribution pattern in the several inner organs from pallial system of Achatina fulica Bowdich, 1822. Also we verified if there is a relationship between the mollusk size and the number of specimens from parasites collected from two touristic villages in Ilha Grande (Angra dos Reis, Rio de Janeiro state): Vila Dois Rios (VDR) and Vila do Abraão (ABR). The samples were obtained through a field work conducted bimonthly during 2007, 2008, 2010, and 2011, at both locations. Height and width were measured from shells collected, and the all specimens were classified in different classes: class 1 - biomass and a larger area of the pallial system, allowing an efficient parasite colonization. Other possible explanation could be the long exposure of the molluscs of class 3 to the parasites, which allowed a longer time to the larvae to allocate themselves.

    Intraerythrocytic parasites are frequently found in fish, including elasmobranchs. The Amazonian rivers present well defined annual hydrological cycles that results in drastic modifications of the environmental conditions with deep implications in the life cycle of the whole associated biota in those fluvial systems. The freshwater stingray Potamotrygon wallacei (stingray cururu) is a new species restricted to the Middle Rio Negro basin and it is subject to strong alterations in their natural habitats (igapós) a result of the constant variations in the water level of Rio Negro. This work demonstrates the occurrence of intraerythrocytic parasite Cyrilia sp. in this stingray species. Additionally, the prevalence and quantification of hemoparasites in different phases of Rio Negro were also established. Field sampling was carried in the Archipelago of Mariuá, Middle Rio Negro, involving different stages of the water cycle. The intraerythrocytic parasites were quantified by direct counting in blood smears using a total counting of 2000 erythrocytes in each blood smear. The presence of parasites intraerythrocytic generates changes in the morphology of blood cell. The largest amount of the hemoparasites was recorded in the drought period. We observed a decreasing tendency in the number of parasites in the blood between the drought periods and inundation. We concluded that the level of Negro River influences the incidence of intraerythrocytic parasites in the cururu stingray and the drought represents the period of larger susceptibility to the infestation.

    2012-01-01

    Full Text Available As Rocky Mountain Spotted Fever is the most common tick-borne disease in South America, the presence of Rickettsia sp. in Amblyomma ticks is a possible indication of its endemicity in certain geographic regions. In the present work, bacterial DNA sequences related to Rickettsia amblyommii genes in A. dubitatum ticks, collected in the Brazilian state of Mato Grosso, were discovered. Simultaneously, Paracoccus sp. was detected in aproximately 77% of A. cajennense specimens collected in Rio de Janeiro, Brazil. This is the first report of Paracoccus sp. infection in a specific tick population, and raises the possibility of these bacteria being maintained and/or transmitted by ticks. Whether Paracoccus sp. represents another group of pathogenic Rhodobacteraceae or simply plays a role in A. cajennense physiology, is unknown. The data also demonstrate that the rickettsial 16S rRNA specific primers used forRickettsia spp. screening can also detect Paracoccus alpha-proteobacteria infection in biological samples. Hence, a PCRRFLP strategy is presented to distinguish between these two groups of bacteria.

Foram atribuídos valores de 0 a 100% tanto para as espécies presentes como para os espaços livres de macrófitas aquáticas que eventualmente pudessem ocorrer dentro dos pontos amostrados. Com os dados referentes ao número de indivíduos e pontos avaliados, foi determinada a frequência relativa de cada espécie. Foram identificadas 13 espécies em todo o reservatório, sendo 12 vasculares e uma de alga-verde (Chlorella spp.. Entre as espécies vasculares, nove eram plantas emersas flutuantes, as quais poderiam estar ou não ancoradas no leito do reservatório: Alternanthera philoxeroides, Brachiaria subquadripara, Cyperus difformis, Echinochloa polystachia var. spectabilis, Eichhornia crassipes, Panicum rivulare, Pistia stratiotes, Salvinia auriculata e Typha angustifolia. Outras três espécies foram encontradas somente em solo firme alagado: Aeschynomene sensitiva, Hedychium coronarium e Mimosa pigra.The objectives of this work were to determine the relative frequency and infestation level of each species present in the Salto Grande Reservoir in Americana-SP. The survey and identification of the aquatic plants were carried out in the Salto Grande reservoir on a boat. Twenty evaluation sites were established along the reservoir, photographed and geo-referenced. Values from 0 to 100% were assigned for both the species present and for the aquatic plants that could possibly occur within the sampled sites. Based on the number of individuals and points evaluated, the relative frequency of each species was determined

    Full Text Available Resumo. Este trabalho teve como objetivo analisar a influência da densidade arbórea e da borda sobre a quantidade e o volume nidal dos ninhos arborícolas de Nasutitermes sp., bem como, verificar a dependência do tamanho desses ninhos e a sua região de fixação em relação à arquitetura arbórea. A coleta de dados foi realizada em outubro de 2005, em um trecho da mata ribeirinha do rio Miranda no Pantanal Miranda-Abobral, sendo feita amostragem da quantidade e volume nidal dos ninhos arborícolas de Nasutitermes sp. e verificado a densidade de árvores de dossel através do método de amostragem por parcelas ao longo de um gradiente de profundidade na mata. Outros valores de arquitetura arbórea em que o ninho servia de abrigo também foram analisados, utilizando-se o coeficiente de correlação de Spearman, o teste de Kruskal-Wallis e o Qui-Quadrado. Dentre os resultados analisados, conclui-se que os ninhos arborícolas de Nasutitermes sp. não estão distribuídos ao acaso na mata. Mas sim, pode-se inferir que a quantidade e volume nidal, os locais de fixação, construção e desenvolvimento desses ninhos arborícolas na mata ribeirinha do rio Miranda sofrem interferência da estrutura arbórea da mata estudada.

As hortaliças, constituídas de 50 amostras de cada variedade, consistiram em: alface (Lactuca sativa, variedades lisa e crespa, escarola (Chichorium sp e agrião (Nasturtium officinale. Os resultados evidenciaram elevados percentuais de contaminação em todas as variedades de hortaliças analisadas, porém as freqüências de protozoários foram maiores no agrião. As amostras de alfaces apresentaram os menores percentuais de contaminação, enquanto que a escarola apresentou valores geralmente situados entre o agrião e as alfaces. Observou-se uma grande variedade de protozoários, cujas freqüências de ocorrência na população residente na Região Metropolitana de São Paulo são igualmente elevadas. Os mais freqüentes foram Entamoeba sp (com 4 e 8 núcleos e Giardia sp. Foram também isolados cistos de Iodamoeba sp, Endolimax sp e Chilomastix sp. Os elevados níveis de contaminação fecal encontrados nas amostras analisadas apontam para a importância dos alimentos na transmissão de protozoários intestinais.

    Full Text Available Rhinoxenus bulbovaginatus n. sp. is described from the nose of Salminus maxillosus (Characidae collected in the basin of the rio Paraná, near the city of Porto Rico, state of Paraná, Brazil. The new species can be differentiated from the other three species in the genus by the morphology of the copulatory complex, vagina, and ventral anchor. The sister group relationship of the known species of Rhinoxenus was determined using techniques of Phylogenetic Systematics (Cladism. The resulting cladogram (C.I.=100% indicates that the new species is most closely related to R. piranhus Kritsky, Boeger and Thatcher, 1988. The other two species of the genus, R. arietinus Kritsky, Boeger and Thatcher, 1988 and R. nyttus Kritsky, Boeger and Thatcher, 1988, both parasites of Anostomidae fishes, have a paraphyletic position in the cladogram, suggesting that the origin of at least one of them can not be associated to cospeciation.

    Full Text Available Este estudo objetivou analisar a importância das Áreas de Preservação Permanente (APP para a manutenção dos remanescentes florestais no município de Sorocaba, SP. O mapa desses remanescentes foi elaborado com base em fotografias aéreas de 2006, e mapas de hidrografia e de declividade foram usados para determinação das APP. Compararam-se dois cenários: real (mata atual e ideal (mata atual acrescida da restauração das APP, com base em métricas da paisagem. Os resultados indicaram que 19% do município se enquadra como APP e, dessa área, apenas 45% possui cobertura florestal. As APP preservadas representam 50% do total de cobertura florestal da paisagem. A restauração das APP representaria aumento de 16,68% para 28% de cobertura florestal da paisagem e possibilitaria o surgimento de fragmentos maiores que 3.000 ha, enquanto no cenário real os maiores fragmentos atingem 300 ha. Os remanescentes florestais se apresentaram intimamente ligados às APP: margens de rios, áreas alagáveis e encostas, onde a ocupação urbana foi dificultada e existe o instrumento legal de proteção. Esse quadro evidencia que as APP possuem papel fundamental na conservação florestal em um município bastante urbanizado, onde as áreas naturais sofrem muita pressão. A avaliação dos cenários mostrou que a incorporação dos dispositivos legais no planejamento e ordenamento territorial subsidia as estratégias voltadas para a manutenção de hábitats naturais e, consequentemente, a diminuição dos efeitos negativos sobre a biodiversidade. Entretanto, as mudanças recentes no Código Florestal podem representar um retrocesso no cenário ambiental nacional diante da crescente urbanização.

    Full Text Available OBJETIVO: Estimar a prevalência de sintomas respiratórios e analisar fatores associados, bem como medidas de pico de fluxo expiratório em escolares. MÉTODOS: Estudo descritivo transversal com escolares de dez a 14 anos de Monte Aprazível, SP. Foram aplicados questionários sobre sintomas de asma e de rinite do protocolo International Study of Asthma and Allergies in Childhood, questões sociodemográficas, fatores predisponentes e antecedentes pessoais e familiares. Foram realizadas medidas repetidas do pico de fluxo expiratório nas crianças e dos níveis de concentração de material particulado (MP2,5 e de black carbon. RESULTADOS: A prevalência de sintomas de asma foi de 11% e de 33,2% de rinite; 10,6% apresentaram mais de quatro crises de sibilos nos últimos 12 meses. Antecedentes familiares para bronquite e rinite associaram-se à presença de asma (p = 0,002 e p < 0,001 e de rinite atuais (p < 0,001 e p < 0,001, respectivamente. Para rinite, houve associação com presença de mofo ou rachadura na casa (p = 0,009. Houve maior freqüência de rinite nos meses de junho a outubro, período de safra da cana de açúcar. Prevalência diária de pico de fluxo expiratório abaixo de 20% da mediana de medidas na criança foi maior em dias com maior concentração de MP2,5. CONCLUSÕES: A prevalência de sintomas de asma está abaixo e a de rinite está acima da média nacional. Ainda que dentro dos níveis aceitáveis, a poluição nos períodos de queima da palha da cana-de-açúcar pode contribuir para a exacerbação de episódios de asma e de rinite.

    Full Text Available The purpose of this paper is to present both the political and educational actions that are the major subjects of bill on management of batteries in Rio Claro city, SP, Brazil. While the political actions refer to the furthering of a bill approved recently in the local Youth Parliament  for presentation in the Board of Aldermen, the educational actions relate to the creation of an environmental education program to orient the disposal of batteries at the municipal level. The National Policy on Solid Waste (Law 12,305 passed in 2010 introduced mechanisms to accomplish the shared responsibility for the lifecycle of batteries (and other products and reverse logistics. This law classified batteries into the category of toxic waste. The study that supported the writing of the bill included an analysis of the existing public and private initiatives on batteries´ collection in Rio Claro seeking treatment in major urban centers having the reverse logistics as a premise. In recognition of the importance of the environmental education program, the local Education Secretariat, supported by Sepladema, has defined a schedule for the lectures to be given in public schools. In addition, an application claiming for reforms in the existing public ecopoints was submitted and approved in the Youth Parliament and forwarded for further approval by Sepladema.

    Full Text Available A sobrevivência de micro-organismos patogênicos na cavidade bucal depende da habilidade de se aderirem ao dente e sintetizarem placas bacterianas, formadas a partir de resíduos da má higienização. Para evitar a formação das placas bacterianas, além da higienização mecânica, podem ser aplicados enxaguatórios bucais, que inibem o crescimento de patógenos. Ao considerar a grande diversidade de marcas de enxaguatórios bucais no mercado, o presente trabalho visou avaliar quatro das principais marcas, quanto à eficácia in vitro na inibição de Streptococcus sp. e Candida albicans. Para tanto, foram utilizados os princípios ativos Clorexidina 0,12%, Triclosan e Fluoreto de Sódio, Cloreto de Cetilpiridínio e Timol, empregado o método de difusão em ágar, para avaliação da formação do halo de inibição. Os melhores resultados obtidos na inibição dos micro-organismos testados foram Clorexidina 0,12% e Triclosan e Fluoreto de Sódio.

    Full Text Available Resumo O entendimento do ciclo hidrológico auxilia no processo de planejamento dos recursos hídricos, em projetos de obras hidráulicas e estudos ambientais. Neste trabalho foi realizada a avaliação dos parâmetros hidrometeorológicos e a quantificação do volume de água em cada uma das principais fases do ciclo hidrológico, permitindo a proposição de um modelo de circulação da água na bacia hidrográfica do rio Sorocaba-SP. Os parâmetros foram estimados com base na equação do balanço hídrico, nos dados históricos de chuva, temperatura e vazão da rede hidrometeorológica existente e nas informações dos processos de outorga de concessão de uso dos recursos hídricos. Considerando-se que a vazão média anual no exutório da bacia acrescida da vazão consumida corresponde ao excedente hídrico do balanço, a diferença entre o valor estimado e o observado foi inferior a 10%. A vazão média anual no exutório da bacia somada a vazão consumida foi 63,9 m3 s-1, o que corresponde à 25% do volume de chuva anual média. O excedente hídrico estimado foi de 56,5 m3 s-1, a ETP 1.011 mm ano-1 e a ETR 999 mm ano-1, adotando-se uma CAD de 25 mm. Essas informações contribuem para o planejamento do uso dos recursos hídricos na bacia.

    Full Text Available Endophytic bacteria isolated from Eichhornia crassipes (Mart Solms., collected in oil contaminated wastewater of effluent generated by Petrobras refinery in Manaus were investigated to determine their potential for producing biosurfactants. Assay with 2.6-dichlorophenol indophenol (DCPIP indicator to verify hydrocarbon biodegradation activity; oil emulsification test; drop-collapse method; surface tension and growth curve of biosurfactant production. The M87 Microbacterium sp. strain chosen for this work was identified by the sequencing of the rDNA region and the chemical characterization was performed by FTIR, UFLC/MS and 1H RMN techniques. The selected bacterial isolate provided 3g L-1 of biosurfactant, using diesel oil as sole carbon source, being efficient in biodegrading oil as demonstrated by the DCPIP test. Fractions obtained by column chromatography were efficient in reducing water surface tension around 40 mN m-1, especially fraction 1, which reduced it to 34.17 mN m-1. The different techniques of chemical analysis used for the identification of the biosurfactant isolate indicated that this is probably a long - chain fatty acid lipid type, which may be used in the future as both biosurfactant in decontamination processes of hydrocarbon-polluted areas or as bioemulsifier in countless processes, since it exhibited no toxicity as determined by Alamar Blue assay.

A primeira seqüência ilustra a transformação de Espodossolo Ferrocárbico (Podzol sobre sedimentos arenosos marinhos para Organossolo (solo orgânico, enquanto a outra mostra a relação entre Gleissolo Háplico (solo glei pouco húmico sobre sedimentos continentais e Espodossolo Ferrocárbico (Podzol em sedimentos areno-quartzosos marinhos. A sedimentação marinha é representada por feixes de restinga arenosos, com zonas embaciadas, propiciando o desenvolvimento de Espodossolos nas partes altas e Organossolos nas partes baixas. Morros isolados inferiores à planície funcionaram como antigas zonas de balizamento desses feixes, que limitaram o sistema deposicional continental, definindo o material marinho como anterior ao continental, onde ocorreu um encaixamento da drenagem próximo ao contato.

    Full Text Available Os roedores podem transmitir enfermidades para o ser humano e animais, além de provocar diversos prejuízos econômicos. Objetivou-se estudar a população de roedores existente em um hospital veterinário universitário e em um fragmento de mata atlântica nativa, ambos os locais localizados na Zona da Mata de Minas Gerais, Brasil. No hospital veterinário, foram analisadas as variáveis espécies, sexo, período reprodutivo, sazonalidade, presença de Leptospira sp. em fragmento renal e anticorpos anti-Leptospira em amostras de soro; os animais silvestre foram analisados segundo a presença de Leptospira sp. em fragmento renal. No hospital veterinário, foram capturados 72 animais, 22 (30,6% caracterizados segundo a espécie Rattus rattus, sendo a maioria (66,7% capturada no setor de pequenos animais. Não foram encontradas diferenças estatisticamente significativas entre machos e fêmeas em período reprodutivo chi2=1,85; p=0,174; alfa=0,05. Houve captura de animais em todos os meses do ano, sendo que os meses janeiro (12,5%, fevereiro (15,2%, maio (15,2% e julho (16,7% apresentaram as maiores proporções e agosto (2,8%, setembro (4,2% e outubro (1,4%, as menores. Não foram encontrados animais positivos para leptospirose através do teste sorológico da microaglutinação e da pesquisa histopatológica.

    Full Text Available Cymothoa spinipalpa sp. nov. (Isopoda, Cymothoidae a buccal cavity parasite of the marine fish, Oligoplites saurus, is described on the basis of eight male specimens and one female. The fish hosts were captured in the coastal waters of Natal, Rio Grande do Norte State, Brazil. In the new species, the anterior margin of the cephalon is doubled ventrally over the bases of the antennae. In this respect, it resembles C. recifea Thatcher & Fonseca, 2005. It differs from that species, however, in being much smaller and having basal carinae on the pereopods 4 to 7 that are small and rounded (not large and pointed. Also, pleopods 2-4 lack the folds and pockets that are present in C. recifea. The new species can be distinguished from all known Cymothoa spp. by the mandibular palps which are entirely covered with small spines in adult males. The mancas of the new species resemble those of Cymothoa oestrum since they have elongate antennae but they are wider and have shorter uropods.Cymothoa spinipalpa sp. nov.

Estratégias competitivas têm sido implementadas visando superar tal desafio e, dentre elas, as alianças estratégicas têm se revelado uma alternativa viável. Nesse contexto, este artigo tem como objetivo investigar o grau de utilização de alianças estratégicas por médias e grandes empresas que compõem os pólos calçadistas do Vale do Rio dos Sinos (RS e de Franca (SP. A pesquisa, classificada como exploratória e descritiva, teve a participação de 54 empresas, sendo 33 do Vale do Rio dos Sinos e 21 de Franca, as quais responderam a um questionário elaborado com perguntas em sua maioria fechadas. A análise dos dados deu-se através da estatística descritiva, aplicando-se freqüência percentual relativa, identificando-se a representativa das respostas obtidas em relação ao conjunto. Principais conclusões: a maioria das empresas tem atividades conjuntas; as empresas estão mais próximas das alianças transacionais do que das estratégicas; as alianças com concorrentes são inexpressivas – predominam fornecedores e clientes; o controle do resultado das alianças é insuficiente; confiança e parceiro adequado são fatores determinantes.ABSTRACTThe new environment of the companies, result of the relative opening of the market caused by the globalization has set a new challenge to assure the continuity of the businesses.

Fish were monthly collected from ponds and tanks for one year. The prevalence rates in fish from tanks and ponds were, respectively, 34.2% and 22.5% for I. multifiliis, and 13% and 54.2% for Trichodina sp. Increased electric conductivity and pH provoked reduction of I. multifiliis infestation. Low oxygen concentration increased Trichodina sp. infestation. The use of salt to increase the electric conductivity of water was a method to control I. multifiliis. Low dissolved oxygen and the addition of organic fertilizer favored the reproduction of Trichodina sp.Investigou-se a relação entre as características da água e a infestação de protozoários parasitos, Icthyophthirius multifiliis e Trichodina sp., em peixe espada, Xiphophorus helleri e em plati, Xiphophorus maculatus, coletados em uma piscicultura de peixes ornamentais no Estado de São Paulo, Brasil. Os peixes foram coletados mensalmente, durante um ano, dos viveiros e das caixas de estocagem. A prevalência da infestação nos peixes das caixas e dos viveiros foram, respectivamente, 34,2% e 22,5% para I. multifiliis e 13% e 54% para Trichodina sp. A elevada condutividade elétrica e o pH da água reduziram a infestação por I. multifiliis. A baixa concentração de oxigênio resultou em aumento na infestação por Trichodina sp. O uso do sal, para aumentar a condutividade elétrica da água, consistiu em um método de controle de I. multifiliis. A redução do oxigênio dissolvido e a adição de fertilizante orgânico favoreceram a reprodução de Trichodina sp.

METHODS The parasites were isolated and a growth curve was performed in NNN and Schneider's media containing 10% foetal bovine serum. Parasite morphology was evaluated via light microscopy on Giemsa-stained culture smears, as well as scanning and transmission electron microscopy. Molecular taxonomy was based on a partial region (737-bp of the small subunit (18S ribosomal RNA gene and 708 bp of the nuclear marker, glycosomal glyceraldehyde-3-phosphate dehydrogenase (gGAPDH genes. Maximum likelihood and Bayesian inference methods were used to perform a species coalescent analysis and to generate individual and concatenated gene trees. Divergence times among species that belong to the T. cruzi clade were also inferred. FINDINGS In vitro growth curves demonstrated a very short log phase, achieving a maximum growth rate at day 3 followed by a sharp decline. Only epimastigote forms were observed under light and scanning microscopy. Transmission electron microscopy analysis showed structures typical to Trypanosoma spp., except one structure that presented as single-membraned, usually grouped in stacks of three or four.

    Full Text Available Desde 1982, a bacia do rio do Bananal (512 km2, que drena o reverso da escarpa Atlântica da serra do Mar (localmente denominada serra da Bocaina, constituiu-se em área-laboratório de pesquisas de campo de natureza hidro-geomorfológica e geoecológica, fornecendo subsídios para a modelagem funcional e histórica da expansão de redes de canais em vales de cabeceiras de drenagem. Ao longo das últimas três décadas foram conduzidas mensurações do crescimento de um caso típico de canal inciso (tipo voçoroca resultante da erosão por exfiltração de água subterrânea. Enquanto o canal-tronco permaneceu relativamente estável nesse período, observou-se o crescimento de dois canais-dígitos, um dos quais bifurcou próximo à cabeça do canal-tronco, mostrando aceleração das taxas de recuo com a aproximação do divisor. Este último fato contrariou o esperado na medida em que a literatura apontava que a redução da área de contribuição a montante da cabeça de canal tenderia a desacelerar a atividade erosiva até sua estabilização final. Isto abriu a hipótese de que estaria ocorrendo migração de fluxo do vale de cabeceira vizinho, o que foi traduzido como “pirataria” de água subterrânea. Neste trabalho buscou-se testar tal possibilidade, visando compreender melhor a relação entre a expansão da rede de canais e o comportamento da rede de fluxos d’água subterrânea local. Para tanto, utilizou-se a modelagem numérica de fluxos subterrâneos, arbitrando-se uma profundidade limite da rocha impermeável em 25 m por aproximação aos dados de campo. Alguns cenários foram reproduzidos a partir do conhecimento sobre a evolução geomorfológica da região. Os resultados da modelagem mostraram que o crescimento da rede de canais promove mudanças na orientação da rede de fluxos d’água subterrânea, podendo concentrar parte da rede de fluxos dos vales de cabeceiras vizinhas, configurando-se uma “pirataria de

Multivariate techniques were applied to determine the correlation between species richness and the order of the rivers, preservation level of the riparian forest, shade level, presence or absence of Eucalyptus, sugar cane and pastures, and surrounding declivity stability of the sites. Species richness was highest at locations with greater vegetation cover and preserved riparian forest.Este trabalho teve o objetivo de examinar se existem associações entre as espécies de peixes e o estado de conservação das matas ciliares na bacia do rio Corumbataí. Foram escolhidos 4 rios principais com 3 pontos de coleta em cada um. Foram realizadas coletas nos períodos de março a junho e de setembro a dezembro de 2001. Técnicas multivariadas foram aplicadas para determinar a correlação entre a riqueza de espécies e a ordem dos rios, estado de preservação da mata ciliar, sombreamento, presença ou ausência de Eucalyptus, cana-de-açúcar e pastagens, e nível de estabilidade do barranco ao redor dos pontos de coleta. A riqueza de espécies foi maior em locais com maior cobertura vegetal e mata ciliar preservada.

    Full Text Available INTRODUÇÃO: O principal mecanismo de resistência entre isolados de Pseudomonas aeruginosa e Acinetobacter sp. é a produção de metalo-β-lactamases (MβLs. As MβLs são enzimas capazes de hidrolisar cefalosporinas, penicilinas e carbapenêmicos, mas não monobactâmicos (aztreonam antibióticos que se encontram entre as principais opções terapêuticas para o tratamento de infecções causadas por bactérias não fermentadoras de glicose. MÉTODOS: Um estudo observacional, transversal, descritivo e retrospectivo foi desenvolvido para avaliar a frequência e o perfil de susceptibilidade cepas de P. aeruginosa e Acinetobacter sp. produtoras de MβLs isoladas no Hospital São Vicente de Paulo, Passo Fundo, Brasil. RESULTADOS: A produção de MβLs foi observada em 77,6% (n = 173/223 dos isolados de P. aeruginosa e em 22,4% (n = 50/223 dos isolados de Acinetobacter sp. Dentre as cepas produtoras de MβL, a maioria apresentou mais de 90% de resistência a seis antimicrobianos dos 12 testados, enfatizando a resistência a ceftazidima, gentamicina, aztreonam, piperaciclina/tazobactam, cefepime, ciprofloxacina, meropenem e tobramicina. CONCLUSÕES: Os índices de MβL encontrados confirmam a preocupação mundial com a disseminação desse mecanismo de resistência.

    The purpose of this research was to study the geochemical behavior of radionuclides and heavy metals in soils of agricultural use at Corumbatai River basin (SP). The natural concentration and variability in sedimentary rocks at Corumbatai river basin follow the trend Ca > Mg > K > Na, with the concentration of heavy metals and radionuclides. The distribution of exposure rate in soils shows the occurrence of higher values towards south of the Corumbatai river basin, region where are applied phosphate fertilizers, amendments and 'vinhaca' in sugar cane crops. Heavy metals and radionuclides incorporated in phosphate fertilizers and amendments are annually added during the fertilization process in the sugar cane crops, but if they are utilized in accordance with the recommended rate, they do not rise the concentration levels in soils up to hazards levels. Thus, they are lower transferred from soils to sugar cane at Corumbatai river basin, not offering hazard to the ecosystem and animal or human health. (author)

    Full Text Available Este estudo trata da proposição e aplicação de técnicas para reconhecimento da  geomorfologia original de planícies fluviais urbanizadas utilizando-se de procedimentos tradicionais e da abordagem histórica em geomorfologia. Tem como foco o reconhecimento de uma paleogeografia e de uma paleogeomorfologia de um trecho do rio Pinheiros, na cidade de São Paulo em seu estágio pré-urbano holocênico com algumas incursões ao Pleistoceno Superior. Dentre os principais resultados destaca-se a produção da carta geomorfológica de detalhe na escala 1:20.000 e a análise de sua aplicação em demandas da gestão territorial urbana. Foram utilizados princípios da cartografia geomorfológica de detalhe, da antropogeomorfologia e da abordagem histórica em geomorfologia (Nir 1983, Goudie, 1997, Rodrigues 2001, Gurnell et al. 2003, e Trimble 2008, realizando-se pesquisa arquivística, fotointerpretação, trabalho de campo, análise de mapas antigos e de dados pedo-estratigráficos disponíveis em recentes relatórios de engenharia do Metrô de S. Paulo. A articulação destes dados em representações espaciais bi-dimensionais permitiu a reconstituição de uma sequência de eventos geomorfológicos atuantes no sistema fluvial no Holoceno e no Pleistoceno Superior. Foi identificada significativa influência da estrutura geológica na evolução holocênica da planície. Por outro lado, identificou-se paleocanal preenchido por depósitos da Formação Itaquaquecetuba que evidenciaram a existência de fluxos fluviais de maior potência comparativamente ao dos canais meândricos holocênicos. Demonstrou-se também a relevância deste conhecimento paleogeográfico e geomorfológico para a gestão territorial urbana e análise de riscos geotécnicos.

A partir de uma transeção, foram escolhidos três perfis representativos dos solos de mangue da área nos quais foram descritas as condições geoquímicas e sua conseqüência sobre a mineralogia de seus respectivos solos. A análise mineralógica (DRX e EDS e as condições físico-químicas encontradas revelam a ocorrência de processos de piritização na área de estudo. A assembléia mineralógica está composta tanto por argilominerais alóctones (caulinitas, micas e esmectitas como por argilominerais autóctones (micas, esmectitas e pirita. A partir de evidências provenientes da DRX e EDS, especula-se a formação de glauconita nestes solos. As condições de halomorfia e hidromorfia determinam valores de Eh e pH sob os quais elementos como Fe2+ e SO encontram-se livres na solução do solo com tendência à estabilidade da pirita (FeS2, favorecendo, portanto, o processo da piritização.

Na Bacia do Rio Corumbataí, SP, os incêndios são um dos causadores de fragmentação e degradação da cobertura florestal. Nesse contexto, este trabalho objetivou a realização do mapeamento de risco de incêndios florestais na Bacia do Rio Corumbataí, utilizando-se a avaliação multicriterial (Método da Média Ponderada Ordenada em um Sistema de Informações Geográficas. Os fatores importantes do estudo foram: declividade do terreno, face de exposição ao sol, pluviosidade, proximidade da malha viária, proximidade dos centros urbanos, proximidade da rede hidrográfica, vizinhança dos fragmentos e face de exposição aos ventos. A combinação dos mapas de fatores resultou no mapa de risco regional da bacia. Para a confecção do mapa de risco em nível de fragmento, determinou-se o risco associado a cada fragmento, a partir da análise de uma faixa de 30 m em seu entorno. O risco foi reclassificado em três classes: baixo, médio e alto. Com base no mapa final, verificou-se que: aproximadamente 20% dos fragmentos de mata nativa pertencem à classe de risco alto, 55% à classe de risco médio e 25% à classe de risco baixo. Nas condições atuais de uso e cobertura do solo, bem como de manejo das áreas agrícolas e pastagens, os remanescentes florestais da Bacia do Rio Corumbataí estão sob séria ameaça de degradação por incêndios florestais.Fire is one of the agents most used in the suppression of forest areas in the State of São Paulo, Brazil, and, when out of control, it can be responsible for the destruction of extensive ecosystems.

    Full Text Available The neonatal period is considered the most effective for the screening of hemoglobinopathies. This allows prophylaxis and prevention, improving the patient's survival and guidance of parents and heterozygote carriers. The present work aims at the early detection of abnormal hemoglobins, the establishment of standard analysis and to examine the viability of the prevention program. Blood samples were collected by heel stick and from blood cord of children born in the Hospital de Base São José do Rio Preto, from April 1998 to November 1999. Electrophoresis and cytological, biochemical, cromatographic analyses were made for abnormal hemoglobin characterization. A total of 1,478 neonatal blood samples were analyzed in which 14.62% presented with hemoglobins alterations: 3.32% had Hb S; 0.61% had Hb C; 7.44% were suggestive of alpha thalassemia; 1.55% were suggestive of beta thalassemia, and 1.70% had alpha/beta thalassemia interactions. The samples collected from the blood cord showed better results in all analyses while the blood samples collected by heel stick on filter paper, were applicable to only specific methodologies. The routine laboratory methods allowed identification of the thalassemic and variant forms, and isoelectric focusing presented sensitivity only for variant identification in this age range. The suspected cases were reassessed after six months, which permitted genetic counseling of their family members and clinic attendance. A multidisciplinary approach in programs of this kind is fundamental for its success.

The patient was sick for 13 days. The disease had an abrupt onset characterized by high fever (39ºC., headache, chills and myalgias for 8 days. In addition, on the 3rd day, the patient developed nauseas and vomiting, and in the 10th, epigastralgia, diarrheia and gengivorrhagia. Leucopenia was seen within the 1 st week of onset, with counts as low as 2,500 white cells per mm³. Counts performed after the 23th day of the onset were within normal limits. With the exception of moderate lymphocitosis, no changes were observed in differential counts. An increase in the liter of antibodies by complement fixation, neutralization and ELISA (IgM was detected. Suckling mice and baby hamsters were inoculated intracerebrally with 0.02 ml of blood samples collected in the 2nd and 7th days of disease. Attempts to isolate the virus were also made in Vero cells. No virus was isolated. This virus was isolated before in a single occasion in São Paulo State, in 1990, from the blood of a patient with hemorrhagic fever with a fatal outcome. The manipulation of the virus under study, must be done carefully, since the transmission can occur through aerosols.São descritos os achados clínico-laboratoriais da infecção acidental pelo virus SP H 114202 (Arenavirus, família Arenaviridae, um virus novo causador de febre hemorrágica humana.

    Full Text Available RESUMO Necrochorume é um efluente gerado a partir da decomposição de corpos. Em cemitérios, a principal causa de poluição subsuperficial é a sua percolação, que altera significativamente o solo, impedindo-o de realizar suas funções naturais. Particularmente no Brasil, pela falta de planejamento consequente do histórico cultural, os cemitérios se localizam totalmente integrados à malha urbana, representando um problema de saúde pública. O risco de contaminação está associado à presença de elementos, como compostos nitrogenados, metais pesados, vírus e bactérias, com riscos inerentes à saúde humana. Na literatura, esses contaminantes têm sido constantemente identificados no ambiente geológico a partir de resultados analíticos de água e solo quando comparados a uma área não impactada. A presente pesquisa objetivou investigar eventuais alterações no meio físico subsuperficial do cemitério municipal da cidade de Rio Claro, São Paulo, por meio dos resultados analíticos dos poços, apoiados por dados obtidos da técnica geofísica da sondagem elétrica vertical (SEV. Os resultados apontaram boa correlação com a evolução espacial e temporal da ocupação do cemitério ao longo de sua história.

    At the world-wide Earth Summit held in Rio de Janeiro in 1992, two new legally binding documents were signed by over 140 countries: the Convention on Climate Change and the Convention on Biological Diversity. These conventions will come into force when ratified by 50 and 30 countries respectively. The objectives of these conventions, the steps to be taken toward their compliance, and their implications for Canada are discussed. Since climatic change could bring about adverse effects such as water shortages and loss of permafrost, Canada has committed itself to a quick start toward compliance with preparation of a detailed national inventory of greenhouse gas emissions. The biodiversity convention could make it harder to develop hydropower in Canada at the same time that the climate change convention makes hydropower more attractive. Other documents from the Earth Summit included declarations on forestry management, sustainable development, and future conventions on desertification and fishing. Notable features of the summit included a refocusing of the environmental agenda to the priorities of the poorer countries, a recognition that environmental issues are linked to poverty and economic development, and an attack on the consumption patterns of the richer countries.

Neste estudo, teve-se como objetivo identificar os principais itens alimentares ingeridos por Cricotopus sp. e comparar as possíveis diferenças na dieta das larvas em diferentes substratos artificiais e fases hídricas. Foram utilizados quatro tipos de substratos artificiais: madeira em forma de X (MADX, placas de nitacetal em forma de X (NITX, PVC em forma de tubo (PVCT e metal galvanizado em forma de tubo (METT, cada um com três réplicas. As coletas foram realizadas quinzenalmente, entre os meses de agosto de 2004 e dezembro de 2005. A dieta de Cricotopus sp. foi constituída por detritos, algas e hifas de fungos. Detrito foi o principal item alimentar, com valores superiores a 50% do total consumido. Os resultados indicaram que Cricotopus sp. é uma espécie coletora e, independentemente do substrato, as larvas alimentam-se dos recursos disponíveis no ambiente. Entretanto, mudanças no regime hidrológico do rio Paraná podem influenciar a disponibilidade de alimento, principalmente algumas diatomaceas como Melosira sp., consumidas em maior quantidade apenas na fase de águas baixasIn Brazil, studies on the diet of Chironomidae larvae are still scarce and these data are important to understand the trophic structure and organization of aquatic ecosystems.

A. arda is a medium size amphisbaenian with a checkered black and white color pattern similar to the one present in the fuliginosa group but differing from that by having a lighter pigmentation, an uniformly white ventral surface, and by several other important morphological characters. A. arda is similar to Amphisbaena vermicularis in meristic characters currently used to assist amphisbaenian identification but can be separated from it by its color pattern, its flatter cephalic shields, and by the more ventral position of the nostril.

    Full Text Available O presente trabalho apresenta os primeiros resultados da avaliação da produção e qualidade do gás para a geração de energia em um aterro sanitário. Foram monitorados parâmetros de qualidade do biogás, pressão exercida pelo sistema e volume de gás extraído. A partir do acompanhamento desses parâmetros, foram feitas três análises em diferentes situações que pudessem explicar o comportamento dos parâmetros: uma análise com poços em diferentes profundidades e duas análises a caráter de comparação: (a poços conectados ao sistema de captação por extração ativa; e (b poços não conectados ao sistema de captação, com extração passiva. Os resultados demonstraram que poços em profundidade intermediária apresentam as maiores produções e qualidade do gás e poços com extração passiva em relação à ativa tiveram diferenças significativas dos parâmetros acompanhados.The present work shows the initial results of the evaluation of production and quality of the landfill gas to energy. Parameters of quality, pressure exerted by the system and volume of extracted landfill gas had been monitored. From the accompaniment of these parameters, three different analyses in different situations could explain the behavior of the wells: one analysis of wells in different depths, and two comparison analyses: (a wells hardwired to the system of collection for active extraction; and (b wells not hardwired to the collection system, with passive extraction. The results demonstrated that wells at intermediate deep have the highest yields and quality of gas and wells with passive extraction in relation to the active ones had significant differences of the monitored parameters.

E-mail: ummaia@usp.br This study aimed to assess the current status of stingless bee beekeeping (meliponiculture in the State of Rio Grande do Norte, Brazil, with the aid of structured questionnaires made during visits to beekeepers. The results were compared with a previous census made in the state and with a similar study from Australia. Meliponiculture in Rio Grande do Norte is still informal and little standardized. The activity has grown in recent years considering the mean number of nests per beekeeper. Most apiaries are formed of up to 50 colonies, usually distributed in the backyards of homes. Twelve species of stingless bees were reared in the state, and the most common was the “Jandaíra” bee (Melipona subnitida, whose honey is considered medicinal. While many beekeepers already know the importance of bees as pollinators, stingless bees are still not used for crop pollination. Compared to a recent analysis of beekeeping in Australia, meliponiculture in Brazil is more traditional, honey is the main product and the number of colonies per beekeeper is much higher. Our results highlight the need to reinforce knowledge about bees and promote specific training aimed at improving and standardizing management practices.

    The Secretary-General of the UN Conference on Environment and Development notes that after the Earth Summit in Rio de Janeiro discussions about the environment and development will differ from those prior to the Summit. These discussions must now incorporate problems of developing countries, poverty, inequalities, flow of resources to developing countries, and terms of trade. The Rio Declaration on Environment and Development consists of important tenets, but it must evolve into an Earth Charter to be endorsed on the 50th anniversary of the UN in 1965. The Summit's Plan of Action, Agenda 21, must also continue to evolve and, despite its shortcomings, is the most extensive and, if implemented, most effective international action ever approved by the international community. Financing the Agenda 21 initiatives remains to be decided. New possible sources of funding must be based n the polluter pays principle and may include new taxes, user charges, emission permits, and citizen funding. Even though the most serious problem in the 1990s is stabilization of atmospheric gases, the Rio agreement does not include targets or timetables. Governments must take united action immediately to reduce carbon dioxide emissions by at least 60%. 1 nation has not yet approved the convention on biological diversity. Governments also need to move forward on conventions on decertification and deforestation. They need to incorporate the global objectives of Agenda 21 into their own national policies and practices. This must also be done at the global, regional, organizational, local, and individual levels. The global community must also begin technology capacity building. The participatory process should also include nongovernmental organizations. Population growth must also slow dramatically to achieve sustainable development. The various participatory levels must consider elimination of poverty.

Este trabalho mostrou que o esgoto doméstico não-tratado de uma população aproximada de 250 mil habitantes da cidade de Campinas, via Ribeirão Anhumas, é a principal fonte de Amônia na bacia do Rio Atibaia, apesar do grande número de indústrias ali presentes.This study evaluated the tolerance capacity and the impairment state of the Atibaia River, considering the threat to aquatic life by the presence of Ammonia, which represents one of the main risks to the aquatic communities in the Atibaia River. With this aim, the method Total Maximum Daily Load (TMDL, from the United States Environmental Protection Agency (EPA, was applied. The results revealed that the Ammonia loads increased progressively through the Atibaia River, especially due to the point sources. The daily Ammonia loads assumed values that ranged from 30 to 5000 kg NH3. The tolerance capacity of the waters of the Atibaia River, to protect aquatic life against the toxic effects of the Ammonia, has been violated in reaches near its mouth. The impairment of these waters was more intense during the dry season. This study showed that the domestic sewer

    The SP-100 Program is expected to go through three phases: technology assessment and advancement, ground testing, and flight qualification. Currently the program is in the two- to three-year technology assessment and advancement stage. Goals are to identify the space nuclear power system concept that best meets anticipated requirements of future space missions, assess the technical feasibility of that concept, and establish a cost and schedule for developing the concept. The SP-100 Project Office has begun the implementation activities needed to meet these goals. With regard to refractory alloys, a better data base will be required before we move ahead in the program from technology assessment to ground demonstration

    Full Text Available O Rio Paraíba do Sul está localizado em uma região brasileira com elevada densidade populacional e grande importância socioeconômica. Em seu trecho paulista, o rio encontra-se impactado e com a qualidade da água comprometida devido à retirada da vegetação ciliar, o aumento de áreas impermeáveis, a atividade industrial, a utilização de insumos agrícolas e, principalmente, pelo lançamento de esgotos sem tratamento adequado. O objetivo deste trabalho foi caracterizar, durante as estações seca e chuvosa, a qualidade da água do Rio Paraíba do Sul quanto as variáveis físicas, químicas, biológicas e ecotoxicológicas em seu trecho médio superior. As coletas das amostras foram realizadas trimestralmente entre os meses de agosto de 2013 e agosto de 2014. Foram determinadas variáveis: pH, temperatura, condutividade, turbidez, oxigênio dissolvido (OD, demanda bioquímica de oxigênio (DBO, demanda química de oxigênio (DQO, fósforo total (PT, sólidos totais (ST, coliformes termotolerantes (CT, clorofila-a, efeito tóxico agudo (ETA e crônico (ETC e Índice de Estado Trófico (IET. Os resultados referentes à qualidade das águas mostraram que as variáveis OD, PT e CT estavam em desacordo com o estabelecido para um rio classe 2, conforme a resolução CONAMA 357/2005 (2005. Algumas variáveis apresentaram uma redução ao longo do período avaliado, como DBO (42,4%, ST (31,1% e DQO (21,3%. No período chuvoso foram observados ETA e ETC. A análise estatística mostrou que a precipitação pluviométrica possui grande influência sobre OD, DBO, ST, clorofila-a, ETA e ETC, atuando como um possível agente intensificador de impactos sobre este manancial.

    Full Text Available A revista Galáxia surgiu no cenário intelectual nacional para atestar que a vitalidade das múltiplas confluências entre Comunicação e Semiótica delimitava um campo de conhecimento maduro capaz de produzir a sua própria revista cientí­fica. Fiel ao seu nome - homenagem a Haroldo de Campos, que, em poema homônimo, sinalizava para o conví­vio entre fronteiras -, a revista assumiu sua vocação transdisciplinar. O Programa de Estudos Pós-Graduados em Comunicação e Semiótica da PUC/SP confiou o projeto inicial do periódico a Irene Machado, que respondeu, de forma notável, pela editoria cientí­fica dos sete primeiros números. A dedicação de Irene Machado contribuiu para consolidar a proposta dos trânsitos e fluxos de idéias como fatores de fomento da diversidade que marca a Comunicação como campo cientí­fico. Sem esse competente trabalho, a revista não teria alcançado o significativo patamar Nacional A na escala de avaliação do sistema Qualis/CAPES. Nessa esteira, feita em nome do Programa, os rigores de edição do presente volume ficaram a cargo de uma comissão composta por Lucrécia D'Aléssio Ferrara, Ana Claudia de Oliveira, Eugênio Trivinho e Helena Katz. Galáxia 8 apresenta uma dupla articulação na seção "Fórum". José Luiz Fiorin mostra as contribuições de uma teoria da significação para a compreensão dos fenômenos comunicacionais, que não se restringem ao âmbito da produção de massa. Eric Landowski, por sua vez, chama a atenção para um outro regime de interpretação das encenações do corpo numa detalhada análise ancorada em quatro dimensões especí­ficas do retrato (mimética, hermenêutica, cosmética e estética, na qual a fotografia dos homens polí­ticos na imprensa é tratada como componente de uma estratégia discursiva midiática global.

    Full Text Available O SRTM - Shutle Radar Topography Mission – é uma missão o qual gerou-se uma base topográfica digital de alta resolução. A SRTM consiste num sistema de radar especialmente modificado que voou a bordo do Endea-vour (ônibus espacial, em fevereiro de 2000. As imagens obtidas pelo SRTM garantiu amplas aplicações em estudos espaciais, uma vez que os processos de comunicação visual para a produção de cartografia de base e mapas de precisão da análise espacial foram utilizados. O presente estudo foi baseado em duas etapas de processamento de dados: inicialmente, incidiu sobre a manipulação de bases vetorizadas (dados de hidrografia obtidos pelo IBGE - Instituto Brasileiro de Geografia e Estatística e, em seguida, gerou-se informações vetorizadas a partir de imagens SRTM. A área de estudo é a Bacia do Rio Grande, MG/SP. Usando o programa de Sistemas de Informação Geográfica - ArcGIS 9.3.1 - foi obtido pelo módulo Spatial Analyst a hidrografia que foi extraída do SRTM. Após essa extração, foram comparadas as informações obtidas com o IBGE (vetor da base de dados utilizando o módulo Arcscan/ArcGIS e as informações obtidas pelo SRTM. Verificou-se uma ligeira diferença entre a distribuição e a concentração dos prováveis canais de drenagem entre os mapas dos vetores gerados (IBGE x SRTM. O trabalho demonstrou o uso dos dados do SRTM possibilitando a atualização de dados da rede hidrográfica de extensas áreas de modo bastante facilitado, com a vantagem de ser organizado pela mesma equipe e pelo mesmo processo metodológico, sem riscos de desigualdades durante sua geração.

    Full Text Available The purpose of this article is to discuss the role of Rock in Rio: The Musical, as herald of megafestival Rock in Rio. Driven by the success that musicals have reached in Brazil, we believe that the design of this spectacle of music, dance and staging renews the brand of the rock festival, once it adds the force of young and healthy bodies to its concept. Moreover, the musical provides Rock in Rio with some distance from the controversal trilogy of sex, drugs and rock and roll, a strong mark of past festivals around the world. Thus, the musical expands the possibilities of growth for the brand.

    Full Text Available Na bacia do rio Corumbataí, a vegetação natural ocupa menos de 3% de sua área total, e a ausência dessa vegetação florestal tem levado ao aumento dos processos erosivos e ao desequilíbrio do regime hídrico de seus rios, causando diversos problemas no abastecimento de água de várias cidades, como Piracicaba e Rio Claro. Desse modo, existe a necessidade de um reflorestamento criterioso em áreas dessa bacia. No entanto, devido à limitação de recursos, é necessário que sejam realizados estudos de seleção de áreas prioritárias para que, com os recursos disponíveis, o ganho ambiental das áreas restauradas seja máximo. O objetivo deste trabalho foi desenvolver um método de priorização de áreas para restauração florestal baseado no uso de indicadores de sustentabilidade em microbacias. Cinco indicadores foram utilizados: porcentagem de mata nativa na APP; descontinuidade da vegetação nativa na bacia; diversidade da paisagem; variação média do uso da terra; e suscetibilidade à erosão. A seleção das microbacias para restauração das áreas de APP foi realizada por meio da ponderação linear dos indicadores e ordenamento das microbacias. Simulação inicial foi realizada para a seleção de 1.000 ha para restauração, e os resultados indicaram que os indicadores representam diferentes aspectos de sustentabilidade das microbacias. O método foi considerado útil na seleção de microbacias em condições extremas, diferenciando aquelas que necessitam de ações de conservação daquelas que necessitam de ações de restauração.In the Corumbataí river basin, State of São Paulo, forest remnants occupy less than 3% of the original total area, and the absence of this natural vegetation has been increasing erosion and disturbing hydrological regime of its streams, causing many problems on water supply in urban areas like Piracicaba and Rio Claro. This situation shows the need of a well planned reforestation in areas

    1992-01-01

    The June 1992 United Nations Conference on Environment and Development (UNCED) in Rio de Janeiro has been planned more as a discussion of environment and development, rather than sustainable development as suggested by the 1987 World Commission on Environment and Development (the Brundtland Commission). The Canadian agenda for UNCED is like that of most of the developed countries, and focuses mainly on climatic change, deforestation, loss of biodiversity in the tropics, and health of the oceans. The agenda of the developing countries is based on the knowledge that most of these global problems have been caused or aggravated by the industrialized countries. The developing countries fear that actions imposed to solve environmental problems will threaten their economic development. A key demand from the developing countries is a commitment by developed countries to reduce their greenhouse gas emissions, leaving space for the developing countries to increase their emissions as they develop. There is little or no pressure on governments in the developed world to come to such a comprehensive deal. For Canada, much remains to be done in setting national priorities, and many of the issues to be discussed at UNCED are under provincial jurisdiction

    Full Text Available Este artigo apresenta os resultados das pesquisas conduzidas no médio vale do rio Paraíba do Sul, na bacia do rio Bananal (518 2Km e adjacências, sobre a formação e crescimento de redes de canais em cabeceiras de drenagem e suas implicações no rebaixamento diferencial dos divisores de bacias de drenagem sob forte controle estrutural. A ênfase recai nas interações geológico-geomorfológicas que regulam a geração de fluxos ascendentes em fraturas subverticais (artesianismo e suas relações com a formação dos regolitos. As discussões focalizam a natureza dos processos geomorfológicos responsáveis por: 1- formação de depressões fechadas em divisores e suas relações com a origem de concavidades estruturais; 2- origem e progressão de canais incisos (tipo voçoroca através das cabeceiras de drenagem; 3- relação entre a incisão linear (ou rebaixamento de nível de base e o recuo dos divisores; 4- - interações hidrológica e erosiva em cabeceiras de drenagem adjacentes; 5- interações hidrológica e erosiva entre vales fluviais adjacentes e topograficamente desnivelados. Os dados revelam que a rede é dominada pelo crescimento regressivo dos canais de primeira ordem sobre os vales de cabeceiras, onde outros canais menores podem se desenvolver e originar vales suspensos próximos aos divisores, bem como que com a progressão da incisão linear dos canais e rebaixamento do nível freático, acentua-se a competição pela água subterrânea entre vales de cabeceiras ou vales fluviais adjacentes, limitando a geração de fluxos artesianos e os desenvolvimentos da rede de canais interconectados, corroborando o preconizado pela Lei de Gilbert (1877.

    Full Text Available The aim of this work was to study the population reduction of the tomato leafminer moth, Tuta absoluta (Meyrick, by Pyemotes sp. in the laboratory. The mite became greenish when fed on caterpillars, pupae, and adults of T. absoluta. The caterpillars and adults of T. absoluta were quickly paralyzed by the mite venom. A single T. absoluta could host many Pyemotes sp, physogastric females, which were allowed to grow on the moth. Pyemotes sp. can be a new alternative for the biological control of T. absoluta. However, this possibility must be better understood before it could be recommended, because Pyemotes sp. could also cause dermatitis in the humans.O ácaro Pyemotes sp. (Acari: Pyemotidae é um parasita de várias espécies de insetos e exibe o processo de fisogastria na reprodução. É registrada a ocorrência de Pyemotes sp. sobre a traça-do-tomateiro, Tuta absoluta (Meyrick, que sofreu redução considerável de suas populações em condições de laboratório. Este ácaro foi observado parasitando larvas, pupas e adultos de T. absoluta e suas fêmeas fisogástricas apresentaram coloração esverdeada. As larvas e adultos de T. absoluta atacados por Pyemotes sp. exibiram paralisia em poucos minutos, devido à injeção de toxinas por parte do ácaro. Observou-se que um único indivíduo de T. absoluta pode suportar muitas fêmeas fisogástricas de Pyemotes sp., permitindo que outra geração do ácaro continuasse a se reproduzir. O ácaro Pyemotes sp. surge como uma possibilidade para o controle biológico de T. absoluta, mas sua utilização deve ser melhor avaliada já que é uma espécie causadora de dermatites em humanos.

    An analysis of synthetic aperture radar data of SP Mountain was undertaken to demonstrate the use of digital image processing techniques to aid in geologic interpretation of SAR data. These data were collected with the ERIM X- and L-band airborne SAR using like- and cross-polarizations. The resulting signal films were used to produce computer compatible tapes, from which four-channel imagery was generated. Slant range-to-ground range and range-azimuth-scale corrections were made in order to facilitate image registration; intensity corrections were also made. Manual interpretation of the imagery showed that L-band represented the geology of the area better than X-band. Several differences between the various images were also noted. Further digital analysis of the corrected data was done for enhancement purposes. This analysis included application of an MSS differencing routine and development of a routine for removal of relief displacement. It was found that accurate registration of the SAR channels is critical to the effectiveness of the differencing routine. Use of the relief displacement algorithm on the SP Mountain data demonstrated the feasibility of the technique.

    2001-01-01

    Settlement and deforestation surrounding the Brazilian town of Rio Branco are seen here in the striking 'herring bone' deforestation patterns that cut through the rainforest. Rio Brancois the capital of the Brazilian state of Acre and is situated near the border with northeastern Bolivia. The town is a center for the distribution of goods, including rubber, metals, medicinal plants, Brazil nuts and timber. Colonization projects in the region are supported by farming, logging activities, and extensive cattle ranching. Much of the surrounding terrain is of a poorly-draining clay hardpan soil, and heavy rainfall periodically converts parts of the forested region to swamp.The large overview image was acquired by the Multi-angle Imaging SpectroRadiometer's vertical-viewing (nadir) camera on July 28, 2000, and covers an area of 336 kilometers x 333 kilometers. A plume of smoke is visible north of the Rio Branco road, which roughly parallels the slender, twisting Rio Abuna. Most of the major rivers in the image provide reference points for state or international (Bolivia-Brazil) boundaries, and flow northeast to the Rio Madeira (east of the smoke plume). The border between Acre and the Bolivian department of Pando is marked by the Rio Abuna. Pando's southern boundary with the department of Beni is marked by the Rio Madre de Dios, the large river in the lower half of the image.The two higher-resolution inset images highlight a settled area north of the town of Rio Branco. These nadir views cover an area of 60 kilometers x 67 kilometers, and were acquired eleven months apart during Terra orbits 3251 and 8144. In the later image, more haze is present, possibly due to smoke from fires on that day. Comparing the two images provides a method of measuring the changes and expansion in the area of cleared land. One newly cleared patch is apparent near the middle of the later image, slightly off to the right. This polygon represents an area of about 16 square kilometers, or 4000

    GNSS navigation satellites are currently being developed by all major players in the science and technology scene, to compete with the GPS system. Because their applications span many different areas, from traffic and cargo control, to geodesy and seismic monitoring, it is required to assess the coherence between the different constellations. BDS is the GNSS system currently developed in China. Its first generation of satellites consisted of 3 geostationnary satellites allowing geolocalisation in China only. In addition to these satellites, other satellites have been launched in geostationnary and geosynchronous orbits, as well as satellites orbiting with a classical GNSS semi-major axis. With these additions, the BDS system possesses 19 operating satellites, and though the system is mostly efficient for geolocalisation in Asia, the satellites are also visible in other parts of the globe. In parallel to the development of the BDS constellation, China has launched the iGMAS (International GNSS Monitoring and Assessment Service) project to develop a global tracking network of multi-GNSS geodetic receivers. One of the goals of this project is to evaluate the efficiency of the BDS constellation as well as the efficiency of the receivers developed by the Chinese laboratories. As part of the Brazilian program COSBAN leaded by the Foreign Affairs Ministry to foster up the science and technology partnership with China, materialized by the collaboration between the Shanghai Astronomical Observatory/CAS and the Observatório Nacional/MCTI, in Rio de Janeiro. Through it the RIOS-iGMAS station was installed at Observatório Nacional, where the RJEP GNSS station already operates as part of the Brazilian reference system. Thus at the Observatório Nacional can be observed satellites from any constellation with both systems of reception, leading to a direct, efficient way to compare the results obtained for each network. In this communication we focus on the determination of the

    A novel yeast species within the Metschnikowiaceae is described based on a strain from the sugarcane (Saccharum sp.) rhizoplane of an organically managed farm in Rio de Janeiro, Brazil. The D1/D2 domain of the large subunit ribosomal RNA gene sequence analysis showed that the closest related species were Candida tsuchiyae with 86.2% and Candida thailandica with 86.7% of sequence identity. All three are anamorphs in the Clavispora opuntiae clade.

Procura propor paradigmas para a definição dos objetos científicos da área desafiada pelo desenvolvimento tecnológico da informação e pela crescente expansão da economia globalizada e da mundialização da cultura. O presente número confirma o projeto em que se aliam comunicação, semiótica, cultura, tecnologia e informação. Nessa integração, e dentre os temas do volume, destaca-se o espaço, que, lido em sua organização e mediação sígnica, permite compreender as dinâmicas culturais que lhe dão suporte. Na seção "Fórum", Manar Hammad, pesquisador francês da Falculté d'Architecture de Versailles, apresenta uma leitura semiótica do Santuário de Bel, conjunto religioso monumental da antiga Síria, situado na cidade de Tadmor-Palmira. Atualmente, o templo não é senão um complexo em ruínas ou pouco conservado, mas ainda oferece à leitura os alicerces de sua construção e os pilares de crenças que nortearam a civilização modelada por valores gregos que atestam um sincretismo básico para a compreensão da cultura do antigo oriente. A leitura da construção semiótica desse conjunto de relações sígnicas permite flagrar os procedimentos de enunciação que superam o âmbito do verbal para atingir a complexidade dos signos não-verbais e, notadamente, do espaço.

    The taxonomic position of three strains from water, soil and lettuce samples was studied by using a polyphasic taxonomic approach. The strains were reported to lack the virulence-encoding genes inv and virF in a previous study. Controversially, API 20 E and some other phenotypic tests suggested that the strains belong to Yersinia pseudotuberculosis, which prompted this polyphasic taxonomic study. In both the phylogenetic analyses of four housekeeping genes (glnA, gyrB, recA and HSP60) and numerical analyses of HindIII and EcoRI ribopatterns, the strains formed a separate group within the genus Yersinia. Analysis of the 16S rRNA gene sequences showed that the strains were related to Yersinia aldovae and Yersinia mollaretii, but DNA-DNA hybridization analysis differentiated them from these species. Based on the results of the phylogenetic and DNA-DNA hybridization analyses, a novel species, Yersinia pekkanenii sp. nov., is proposed. The type strain is ÅYV7.1KOH2(T) ( = DSM 22769(T)  = LMG 25369(T)).

    Full Text Available PURPOSE: The aim of this study was to standardize the methods of sample collection of mucus from the digestive tract and to determine the microbiota in healthy volunteers from Brazil, collecting samples from the mouth, esophagus, stomach, duodenum, jejunum, ileum, colon, and rectum. METHODS: Microbiota of selected healthy volunteers from the oral cavity (n=10, the esophagus (n=10, the upper digestive tract (n=20, and the lower digestive tract (n=24 were evaluated through distinct collection methods. Collection methods took into account the different sites, using basic scraping and swabbing techniques, stimulated saliva from the oral cavity, irrigation-aspiration with sterile catheters especially designed for the esophagus, a probe especially designed for upper digestive tract, and a special catheter for the lower digestive tract. RESULTS: (i Mixed microbiota were identified in the oral cavity, predominantly Gram-positive aerobic and anaerobic cocci; (ii transitional flora mainly in the esophagus; (iii Veillonella sp, Lactobacillus sp, and Clostridium sp in the stomach and duodenum; (iv in the jejunum and upper ileum, we observed Bacteroides sp, Proteus sp, and Staphylococcus sp, in addition to Veillonella sp; (v in the colon, the presence of "nonpathogenic" anaerobic bacteria Veillonella sp (average 10(5 UFC indicates the existence of a low oxidation-reduction potential environment, which suggests the possibility of adoption of these bacteria as biological markers of total digestive tract health. CONCLUSIONS: The collection methods were efficient in obtaining adequate samples from each segment of the total digestive tract to reveal the normal microbiota. These procedures are safe and easily reproducible for microbiological studies.OBJETIVO: Padronizar os métodos de coleta do muco do trato digestivo e determinar a microbiota, em voluntários saudáveis no Brasil, coletando amostras da boca, esôfago, estômago, duodeno, jejunos e íleo, c

    There are plans to test the SP-100 space reactor for 2 yr in the test facility shown in Figure 1. The vacuum vessel will be in the reactor experiment (RX) cell surrounded by an inert gas atmosphere. It is proposed that the reactor test cell could contain removable-water- shielding tanks to reduce the residual activation dose rates in the test cell after the tests are completed. This reduction will allow the facility to be considered for other uses after the SP-100 tests are completed. The radiation dose rates in the test cell were calculated for several configurations of water-shielding tanks to help evaluate this concept

A explotação deste recurso natural, baseada somente no extrativismo não sustentável acaba por ameaçar os estoques naturais com a sobrepesca. Baseado neste fato, uma avaliação das condições dos estoques naturais desse animal torna-se importante para futuros projetos de conservação e manejo sustentáveis do recurso. Neste trabalho foram levantados dados referentes aos estoques da ostra Crassostrea sp. de três bancos naturais distintos, sendo estes, um na Ilha da Cotinga, na foz do Rio Maciel e outro na foz do Rio Biguaçú. Em cada banco, foram feitas três amostragens aleatórias durante a maré baixa sizígia utilizando-se de um quadrado de amostragem com dimensão de 30x30 cm. Observamos também neste trabalho que, dos locais de estoques naturais da ostra nativa Cras- sostrea sp. presentes na Baía de Paranaguá, o da Ilha da Cotinga apresenta signifi cativamente os maiores valores quanto ao tamanho se comparados com a o Rio Maciel e o Rio Biguaçú, sendo que, entre os dois últimos, o primeiro apresentou maiores valores. Porém, não houve diferenças signifi cativas nos valores biométricos encontrados entre os bancos amostrados nos respectivos bosques.

Several diagnostic loci and fixed differences were observed for each population at loci Acp-A, Gcdh-A and Mdhp-A. Thus, all populations were genetically distinct, although there were many common alleles. The unbiased genetic identities of Nei (I were estimated as 0.780 for Hypostomus sp. 1 and H. strigaticeps, 0.357 for H. strigaticeps and Hypostomus sp. 2 and 0.322 for Hypostomus sp. 1 and Hypostomus sp. 2. The data indicate that the two morphotypes are distinct species from Hypostomus strigaticeps.

    Perhaps the most published graphic in the oil industry is one that traces the price of oil through time. It is used as an overlay to correlate everything from the history of rig activity levels to predicting coming oil shortages and gluts. In Rio de Janeiro this month during the 17th World Petroleum Congress, Dr Don Paul of ChevronTexaco and Saudi Aramco's Abdulaziz Al-Kaabi used it to illustrate the role research and technology development must play within the oil industry. The author discusses the way the oil industry is spending money on research and development, he explains that in the past 20 years the biggest innovation in the industry has been 3D seismic. The critical strategy for oil business was the adaptation of 3D seismic from another industry which was then moulded for its own needs. The article goes on to describe the importance of the development of a portfolio of research and development

    Full Text Available Ticks were obtained from dogs from February to September of 1999 at weekly intervals, in the County of Piraí, State of Rio de Janeiro. Four hundred seventy four ixodids were taxonomically identified, 103 Amblyomma cajennense, seven Amblyomma ovale, 209 Rhipicephalus sanguineus, and 155 Amblyomma sp. An hemolymph test associated with Giemsa's stain revealed two specimens in 163 ticks tested (R. sanguineus and Amblyomma sp, containing rickettsia-like organisms. Direct immunofluorescence verified the presence of spotted fever group rickettsia in one specimen of R. sanguineus. Considering the limited information on rickettsiosis in Brazil, principally in relation to the vectors involved in perpetuating it in foci, these preliminary results give us an idea on the importance of infection in ticks, allowing to expand our knowledge on this zoonosis.

    Full Text Available This research aimed to evaluate the secondary effects of secondary metabolites produced by streptomycetes on spore germination and mycelial growth of the phytopathogenic fungi Cladosporium fulvum Cooke and Fusarium oxysporium f. sp. lycopersici from tomato plants. Metabolites produced by streptomycete isolates codified as AC-147 and AC-92 caused 94.1% inhibition of C. fulvum while AC-95 isolate caused 33.9% inhibition. AC-92 was the most efficient for F. oxysporum f. sp. lycopersici, causing 94.2% inhibition of spore germination. For mycelial growth, AC-26 and AC-92 were the most efficient in inhibiting C. fulvum growth by 46.6% and F. oxysporum f. sp. lycopersici by 29.9%. These streptomycetes are potential agents for biocontrol development methods of these tomato plant pathogenic fungi.Este trabalho teve como objetivo avaliar o efeito de metabólitos secundários produzidos por estreptomicetos na germinação de esporos e no crescimento micelial dos fungos Cladosporium fulvum Cooke e Fusarium oxysporum sp. f. lycopersici da cultura do tomateiro.

    Several species of the genus Penicillium were isolated during a survey of the mycobiota of leaf litter and soil in Colombian Amazon forest. Five species, Penicillium penarojense sp. nov. (type strain CBS 113178(T) = IBT 23262(T)), Penicillium wotroi sp. nov. (type strain CBS 118171(T) = IBT 23253(T)), Penicillium araracuarense sp. nov. (type strain CBS 113149(T) = IBT 23247(T)), Penicillium elleniae sp. nov. (type strain CBS 118135(T) = IBT 23229(T)) and Penicillium vanderhammenii sp. nov. (type strain CBS 126216(T) = IBT 23203(T)) are described here as novel species. Their taxonomic novelty was determined using a polyphasic approach, combining phenotypic, molecular (ITS and partial β-tubulin sequences) and extrolite data. Phylogenetic analyses showed that each novel species formed a unique clade for both loci analysed and that they were most closely related to Penicillium simplicissimum, Penicillium janthinellum, Penicillium daleae and Penicillium brasilianum. An overview of the phylogeny of this taxonomically difficult group is presented, and 33 species are accepted. Each of the five novel species had a unique extrolite profile of known and uncharacterized metabolites and various compounds, such as penicillic acid, andrastin A, pulvilloric acid, paxillin, paspaline and janthitrem, were commonly produced by these phylogenetically related species. The novel species had a high growth rate on agar media, but could be distinguished from each other by several macro- and microscopical characteristics.

    Full Text Available This paper proposes to discuss the transformation of urban landscapes in the Paraíba River Valley as members of the coffee elite emerged in this area and a specific landscape configuration was projected there based on the use of imperial palms ( Roystonea oleracea. Chronologically speaking, the paper covers a period from 1808 to 1911; with regard to space, it focuses on the stretch between Rio de Janeiro and São Paulo, with a closer look at the case of the city of Lorena (SP, so as to encompass all the changes that took place in this region from the introduction to the decline of coffee growing as an economic activity. The urban changes during this period were accompanied by the advent and consolidation of landscapes typical of the society of coffee growers: streets lined with palm trees, a token of their close connections with the royal court, a display of their adherence to “Frenchified customs”. Such configurations were used to characterize public areas and raise them to the same status as the new buildings that gradually replaced those built in colonial style. The paper is structured around three key moments, namely: the introduction of imperial palms in Rio de Janeiro and their association with the idea of nobility and rank, and consequently with neoclassical architecture, which was brought to the colony by the 1816 French Mission; the dissemination of the use of imperial palms as a landscaping resource typical of public spaces from the royal court to the capital of São Paulo, particularly by the coffee barons during the second period of monarchic rule; and, finally, the hypothesis that the use of imperial palms to embellish public areas in São Paulo may have been introduced by a Lorena citizen associated with the coffee elite, albeit later, when Brazil was already a republic

    Bats are ancient hosts of Trypanosoma species and their flying ability, longevity and adaptability to distinct environments indicate that they are efficient dispersers of parasites. Bats from Acre state (Amazon Biome) were collected in four expeditions conducted in an urban forest (Parque Zoobotânico) and one relatively more preserved area (Seringal Cahoeira) in Rio Branco and Xapuri municipalities. Trypanosoma sp. infection was detected by hemoculture and fresh blood examination. Isolated parasite species were identified by the similarity of the obtained DNA sequence from 18S rDNA polymerase chain reaction and reference strains. Overall, 367 bats from 23 genera and 32 species were examined. Chiropterofauna composition was specific to each municipality, although Artibeus sp. and Carollia sp. prevailed throughout. Trypanosoma sp. infection was detected in 85 bats (23·2%). The most widely distributed and prevalent genotypes were (in order) Trypanosoma cruzi TcI, T. cruzi marinkellei, Trypanosoma dionisii, T. cruzi TcIV and Trypanosoma rangeli. At least one still-undescribed Trypanosoma species was also detected in this study. The detection of T. cruzi TcI and TcIV (the ones associated with Chagas disease in Amazon biome) demonstrates the putative importance of these mammal hosts in the epidemiology of the disease in the Acre State.

    Intestinal parasitic infections are considered a serious public health problem and widely distributed worldwide, mainly in urban and rural environments of tropical and subtropical countries. Globally, soil-transmitted helminths and protozoa are the most common intestinal parasites. Blastocystis sp. is a highly prevalent suspected pathogenic protozoan, and considered an unusual protist due to its significant genetic diversity and host plasticity. A total of 294 stool samples were collected from inhabitants of three rural valleys in Rio de Janeiro, Brazil. The stool samples were evaluated by parasitological methods, fecal culture, nested PCR and PCR/Sequencing. Overall prevalence by parasitological analyses was 64.3% (189 out of 294 cases). Blastocystis sp. (55.8%) was the most prevalent, followed by Endolimax nana (18.7%), Entamoeba histolytica complex (7.1%), hookworm infection (7.1%), Entomoeba coli (5.8%), Giardia intestinalis (4.1%), Iodamoeba butchilii (1.0%), Trichuris trichiura (1.0%), Pentatrichomonas hominis (0.7%), Enterobius vermicularis (0.7%), Ascaris lumbricoides (0.7%) and Strongyloides stercoralis (0.7%). Prevalence of IPIs was significantly different by gender. Phylogenetic analysis of Blastocystis sp. and BLAST search revealed five different subtypes: ST3 (34.0%), ST1 (27.0%), ST2 (27.0%), ST4 (3.5%), ST8 (7.0%) and a non-identified subtype. Our findings demonstrate that intestinal parasite infection rates in rural areas of the Sumidouro municipality of Rio de Janeiro, Brazil are still high and remain a challenge to public health. Moreover, our data reveals significant genetic heterogeneity of Blastocystis sp. subtypes and a possible novel subtype, whose confirmation will require additional data. Our study contributes to the understanding of potential routes of transmission, epidemiology, and genetic diversity of Blastocystis sp. in rural areas both at a regional and global scale.

    Breakthrough: A novel catalyzed direct highly selective C(sp2)-C(sp) bond functionalization of alkynes to amides has been developed. Nitrogenation is achieved by the highly selective C(sp2)-C(sp) bond cleavage of aryl-substituted alkynes. The oxidant-free and mild conditions and wide substrate scope make this method very practical. Copyright © 2013 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

    Gram-negative, non-spore-forming, rod-shaped bacteria, T7-09(T) and TR6-08(T), were isolated from soil from a ginseng field in South Korea and characterized to determine their taxonomic position. 16S rRNA gene sequence analysis showed that the two isolates shared 99.5 % sequence similarity. Strains T7-09(T) and TR6-08(T) were shown to belong to the Proteobacteria and showed the highest levels of sequence similarity to Pseudoxanthomonas broegbernensis DSM 12573(T) (98.1 %), Pseudoxanthomonas mexicana AMX 26B(T) (97.4-97.5 %), Pseudoxanthomonas japonensis 12-3(T) (96.5-96.6 %), Pseudoxanthomonas taiwanensis ATCC BAA-404(T) (95.7 %) and Xanthomonas campestris ATCC 33913(T) (96.3-96.5 %). The sequence similarity values with respect to any species with validly published names in related genera were less than 96.5 %. The detection of a quinone system with Q-8 as the predominant compound and a fatty acid profile with C(15 : 0) iso as the predominant acid supported the assignment of the novel isolates to the order 'Xanthomonadales'. The two isolates could be distinguished from the established species of the genus Pseudoxanthomonas by the presence of quantitative unsaturated fatty acid C(17 : 1) iso omega9c and by their unique biochemical profiles. The results of DNA-DNA hybridization clearly demonstrated that T7-09(T) and TR6-08(T) represent separate species. On the basis of these data, it is proposed that T7-09(T) (=KCTC 12208(T)=IAM 15116(T)) and TR6-08(T) (=KCTC 12207(T)=IAM 15115(T)) be classified as the type strains of two novel Pseudoxanthomonas species, for which the names Pseudoxanthomonas koreensis sp. nov. and Pseudoxanthomonas daejeonensis sp. nov., respectively, are proposed.

  11. Glyphosate catabolism by Pseudomonas sp

    International Nuclear Information System (INIS)

    Shinabarger, D.L.

    1986-01-01

    The pathway for the degradation of glyphosate (N-phosphonomethylglycine) by Pseudomonas sp. PG2982 has been determined using metabolic radiolabeling experiments. Radiorespirometry experiments utilizing [3- 14 C] glyphosate revealed that approximately 50-59% of the C3 carbon was oxidized to CO 2 . Fractionation of stationary phase cells labeled with [3- 14 C]glyphosate revealed that from 45-47% of the assimilated C3 carbon is distributed to proteins and that amino acids methionine and serine are highly labeled. The nucleic acid bases adenine and guanine received 90% of the C3 label that was incorporated into nucleic acids, and the only pyrimidine base labeled was thymine. Pulse labeling of PG2982 cells with [3- 14 C]glyphosate revealed that [3- 14 C]sarcosine is an intermediate in glyphosate degradation. Examination of crude extracts prepared from PG2982 cells revealed the presence of an enzyme that oxidizes sarcosine to glycine and formaldehyde. These results indicate that the first step in glyphosate degradation by PG2982 is cleavage of the carbon-phosphorus bond, resulting in the release of sarcosine and a phosphate group. The phosphate group is utilized as a source of phosphorus, and the sarcosine is degraded to glycine and formaldehyde. Phosphonate utilization by Pseudomonas sp. PG2982 was investigated. Each of the ten phosphonates tested were utilized as a sole source of phosphorus by PG2982. Representative compounds tested included alkylphosphonates, 1-amino-substituted alkylphosphonates, amino-terminal phosphonates, and an arylphosphonate. PG2982 cultures degraded phenylphosphonate to benzene and produced methane from methylphosphonate. The data indicate that PG2982 is capable of cleaving the carbon-phosphorus bond of several structurally different phosphonates

    2015-01-01

    Full Text Available The SP100 family members comprise a set of closely related genes on chromosome 2q37.1. The widely expressed SP100 and the leukocyte-specific proteins SP110 and SP140 have been associated with transcriptional regulation and various human diseases. Here, we have characterized the SP100 family member SP140L. The genome sequence analysis showed the formation of SP140L gene through rearrangements of the two neighboring genes, SP100 and SP140, during the evolution of higher primates. The SP140L expression is interferon-inducible with high transcript levels in B cells and other peripheral blood mononuclear cells. Subcellularly, SP140L colocalizes with SP100 and SP140 in nuclear structures that are devoid of SP110, PML, or p300 proteins. Similarly to SP100 and SP140 protein, we detected serum autoantibodies to SP140L in patients with primary biliary cirrhosis using luciferase immunoprecipitation system and immunoblotting assays. In conclusion, our results show that SP140L is phylogenetically recent member of SP100 proteins and acts as an autoantigen in primary biliary cirrhosis patients.

    TurboSP was originally proposed as an alternative to Full stream in LHCb data flow. TurboSP is a data flow strategy which not only selects events that should be preserved, like in Full stream, but also provides selective persistence. This is achieved by saving candidates and subset of the reconstruction. During this summer project we investigated the physics viability of using TurboSP with the topological lines and found out a possibility to reduce the number of kept tracks per event by two times while keeping a ratio of fully picked up interesting decay modes on $\\sim 97 \\%$ level.

    Full Text Available Abstract Although sheep farming has grown in the state of Acre over the past four decades, little is known about occurrences of helminthiases in the herds of this region. The objective of the study was to assess the occurrences of non-intestinal helminthiasis among sheep slaughtered in Rio Branco. A total of 110 sheep livers were inspected from two slaughter batches (july 2014 and march 2015 in a slaughterhouse in Rio Branco. Livers with macroscopic lesions were photographed and were then subjected to histopathological analysis under an optical microscope. The macroscopic lesions showed small nodes with inflammatory characteristics and areas of fibrosis, which appeared to be calcified, thus suggesting a granulomatous reaction. Of the 110 evaluated livers, we noticed 110 nodules in total; these nodules have an average size of 0.5 cm. The histopathological analysis showed alterations to the architecture of the hepatic lobe, with multiple foci of necrosis and polymorphonuclear cells. Two samples revealed the presence of helminths from Nematode class and Capillaria sp. eggs identified by the typical morphology and morphometry. This seems to be the first report of Capillaria sp. in sheep livers in Brazil, and it serves as an important alert regarding animal health surveillance and control and regarding the Capillaria sp. zoonotic role in humans.

    Full Text Available Honey from stingless bees (Melipona sp. is a nutritious and medicinal product economically valued in the informal Brazilian market, driven by the growing demand for natural products; however, its physicochemical characteristics are still unknown. Thus, the aim of this study is to evaluate the physicochemical profile of the stingless bee honey produced in Cruzeiro do Sul, Acre. Honey samples were analyzed following the methodology recommended by Ministério da Agricultura, Pecuária e Abastecimento; the following parameters were established: moisture, total sugars, reducing sugars, apparent sucrose, ash, crude protein, diastase activity, Brix degrees, free acidity, lactonic acidity, total acidity, pH, hydroxymethylfurfural, electrical conductivity, color and Lugol, Lund and Fiehe reactions. Results show that these parameters are not suitable for all samples, being incompatible with established standards, indicating that the current legislation on Apis mellifera is not suitable for all characters analyzed, mainly moisture content, corroborating the need to standardize guidelines for honey from stingless bees. Moreover, there was no tampering in the honeys analyzed.

    Full Text Available Four sp2–sp3 hybrid carbon allotropes are proposed on the basis of first principles calculations. These four carbon allotropes are energetically more favorable than graphite under suitable pressure conditions. They can be assembled from graphite through intralayer wrinkling and interlayer buckling, which is similar to the formation of diamond from graphite. For one of the sp2–sp3 hybrid carbon allotropes, mC24, the electron diffraction patterns match these of i-carbon, which is synthesized from shock-compressed graphite (H. Hirai and K. Kondo, Science, 1991, 253, 772. The allotropes exhibit tunable electronic characteristics from metallic to semiconductive with band gaps comparable to those of silicon allotropes. They are all superhard materials with Vickers hardness values comparable to that of cubic BN. The sp2–sp3 hybrid carbon allotroes are promising materials for photovoltaic electronic devices, and abrasive and grinding tools.

    1979-01-01

    A classification of nuclear states according to the noncompact sympletic Lie algebras sp(2n,R), n = 1, 2, 3, is investigated. Such a classification has recently been shown to be physically meaningful. This classification scheme is the appropriate generalization fo Elliott's SU 3 model of rotational states in deformed light nuclei to include core excitations. A restricted classification according to the Lie algebra, sp(4,R), is motivated. Truncation of the model space to a single sp(4,R) irreducible representation allows the inclusion of states possessing very high excitation energy. An sp(4,R) model study is performed on S = T = 0 positive-parity rotational bands in the deformed light nuclei 16 O and 24 Mg. States are included in the model space that possess up to 10h ω in excitation energy. Results for the B(E2) transition rates compare favorable with experiment, without resort to effective charges

    1992-01-01

    The SP-100 reactor will operate at temperatures up to 1500K in high vacuum. To address the SP-100 needs, a tribology development program has been established at GE to investigate candidate coating materials. Materials were selected based on their high thermodynamic stability, high melting point, compatibility with the substrate, and coefficients of thermal expansion similar to niobium-1% zirconium-the candidate structural material for SP-100. An additional requirement was that the deposition processes should be commercially available to coat large components. This paper presents the details regarding the SP-100 Tribology Development Program including background information, specific bearing requirements, basis for coating material selection, testing methods and the initial results covering the early years of this program

  2. Nickel-resistance determinants in Acidiphilium sp. PM identified by genome-wide functional screening.

    Directory of Open Access Journals (Sweden)

    Patxi San Martin-Uriz

    Full Text Available Acidiphilium spp. are conspicuous dwellers of acidic, metal-rich environments. Indeed, they are among the most metal-resistant organisms; yet little is known about the mechanisms behind the metal tolerance in this genus. Acidiphilium sp. PM is an environmental isolate from Rio Tinto, an acidic, metal-laden river located in southwestern Spain. The characterization of its metal resistance revealed a remarkable ability to tolerate high Ni concentrations. Here we report the screening of a genomic library of Acidiphilium sp. PM to identify genes involved in Ni resistance. This approach revealed seven different genes conferring Ni resistance to E. coli, two of which form an operon encoding the ATP-dependent protease HslVU (ClpQY. This protease was found to enhance resistance to both Ni and Co in E. coli, a function not previously reported. Other Ni-resistance determinants include genes involved in lipopolysaccharide biosynthesis and the synthesis of branched amino acids. The diversity of molecular functions of the genes recovered in the screening suggests that Ni resistance in Acidiphilium sp. PM probably relies on different molecular mechanisms.

    Abstract Rhodnius marabaensis sp. n. was collected on 12 May 2014 in the Murumurú Environmental Reserve in the city of Marabá, Pará State, Brazil. This study was based on previous consultation of morphological descriptions of 19 Rhodnius species and compared to the identification key for the genus Rhodnius. The examination included specimens from 18 Rhodnius species held in the Brazilian National and International Triatomine Taxonomy Reference Laboratory in the Oswaldo Cruz Institute in Rio de Janeiro, Brazil. The morphological characteristics of the head, thorax, abdomen, genitalia, and eggs have been determined. Rhodnius prolixus and Rhodnius robustus were examined in more detail because the BLAST analysis of a cyt-b sequence shows they are closely related to the new species, which also occurs in the northern region of Brazil. The most notable morphological features that distinguish Rhodnius marabaensis sp. n. are the keel-shaped apex of the head, the length of the second segment of the antennae, the shapes of the prosternum, mesosternum and metasternum, the set of spots on the abdomen, the male genitalia, the posterior and ventral surfaces of the external female genitalia, and the morphological characteristics of the eggs. Rhodnius jacundaensis Serra, Serra & Von Atzingen (1980) nomen nudum specimens deposited at the Maraba Cultural Center Foundation - MCCF were examined and considered as a synonym of Rhodnius marabaensis sp. n.

    Full Text Available Drought is a major threat to agriculture production worldwide. Mitogen-activated protein kinases (MAPKs play a pivotal role in sensing and converting stress signals into appropriate responses so that plants can adapt and survive. To examine the function of MAPKs in the drought tolerance of tomato plants, we silenced the SpMPK1, SpMPK2, and SpMPK3 genes in wild-type plants using the virus-induced gene silencing (VIGS method. The results indicate that silencing the individual genes or co-silencing SpMPK1, SpMPK2, and SpMPK3 reduced the drought tolerance of tomato plants by varying degrees. Co-silencing SpMPK1 and SpMPK2 impaired abscisic acid (ABA-induced and hydrogen peroxide (H2O2-induced stomatal closure and enhanced ABA-induced H2O2 production. Similar results were observed when silencing SpMPK3 alone, but not when SpMPK1 and SpMPK2 were individually silenced. These data suggest that the functions of SpMPK1 and SpMPK2 are redundant, and they overlap with that of SpMPK3 in drought stress signaling pathways. In addition, we found that SpMPK3 may regulate H2O2 levels by mediating the expression of CAT1. Hence, SpMPK1, SpMPK2, and SpMPK3 may play crucial roles in enhancing tomato plants’ drought tolerance by influencing stomatal activity and H2O2 production via the ABA-H2O2 pathway.

    1975-01-01

    Samples of ''sandstone'' from near the site of the upper Rio Blanco nuclear explosion were heated in the laboratory at temperatures between 600 and 900 0 C. The composition and amount of noncondensable (dry) gas released were measured and compared to the amount and composition of gas found underground following the explosion. The gas released from the rock heated in the laboratory contained approximately 80 percent CO 2 and 10 percent H 2 ; the balance was CO and CH 4 . With increasing temperature, the amounts of CO 2 , CO, and H 2 released increased. The composition of gas released by heating Rio Blanco rock in the laboratory is similar to the composition of gas found after the nuclear explosion except that it contains less natural gas (CH 4 , C 2 H 6 . . .). The amount of noncondensable gas released by heating the rock increases from approximately 0.1 mole/kg of rock at 600 0 C to 0.9 mole/kg at 900 0 C. Over 90 percent of the volatile components of the rock are released in less than 10 h at 900 0 C. A comparison of the amount of gas released by heating rock in the laboratory to the amount of gas released by the heat of the Rio Blanco nuclear explosion suggests that the explosion released the volatile material from about 0.42 mg of rock per joule of explosive energy (1700 to 1800 tonnes per kt).

    2015-03-20

    The Rio Grande Gorge is a 115 km long river canyon located in Southern Colorado (15 km) and Northern New Mexico (100 km). The majority of the canyon is under the administration of the Bureau of Land Management {BLM), and 77 km of the canyon south of the Colorado/New Mexico border are designated Wild River under the National Wild and Scenic Rivers Act of 1968. Visits I have made to the Rio Grande Gorge over the past 15 .years disclosed some raptor utilization. As the Snake River Birds of Prey Natural Area gained publicity, its similarity to the Rio Grande Gorge became obvious, and I was intrigued by the possibility of a high raptor nesting density in the Gorge. A survey in 1979 of 20 km of the northern end of the canyon revealed a moderately high density of red-tailed hawks and prairie falcons. With the encouragement of that partial survey, and a need to assess the impact of river-running on nesting birds of prey, I made a more comprehensive survey in 1980. The results of my surveys, along with those of a 1978 helicopter survey by the BLM, are presented in this report, as well as general characterization of the area, winter use by raptors, and an assessment of factors influencing the raptor population.

    Full Text Available The 1992 Rio Earth Summit was of paramount importance in the consolidation and international dissemination of environmental impact assessment, officially recognized as a tool for informed decision-making towards sustainable development (Principle 17, Rio Declaration and for protection of biodiversity (Article 14, Convention on Biological Diversity. A significant development afterwards was the strengthening of strategic environmental assessment in the design of policies, plans and programs. Both forms of impact assessment can establish the necessary connections between one goal of the Rio+20 Conference - reaching an agreement on the transition to a green economy - and the underpinning decision making processes. Although the Rio+20 Summit has faced challenges to acknowledge its potential, impact assessment should be strengthened in support of both government and business decisions.La Cumbre de la Tierra de 1992 fue de la más grande importancia en la consolidación y diseminación de la evaluación de impacto ambiental, oficialmente reconocida como una herramienta para la toma de decisiones informada hacia el desarrollo sostenible (Principio 17, Declaración de Rio y para la protección de la biodiversidad (Artículo 14, Convención de la Diversidad Biológica. Un avanzo posterior importante fue el fortalecimiento de la evaluación ambiental estratégica en la preparación de políticas, planos y programas. Ambas formas de evaluación de impacto son capaces de establecer los necesarios vínculos entre un objetivo declarado de la Conferencia Rio+2- - llegar a un acuerdo sobre la transición para una economía verde - y los procesos decisorios subyacentes.

    Full Text Available Aplicação da tecnologia na agricultura dentro do sistema de produção é realidade principalmente com a abertura de mercados através da globalização. Em diversas áreas da indústria moderna, o calcário é utilizado como corretor da acidez do solo. A calagem é uma prática barata, porém ainda é negligenciada quanto ao seu uso, na adoção da técnica, à definição das doses e às formas de aplicação. A briquetagem consiste na aglomeração de partículas finas através de pressão, auxiliada ou não por aglomerantes, permitindo obtenção de produtos compactados, com forma, tamanho e parâmetros mecânicos adequados. A redução de volume do material, além dos benefícios tecnológicos, permite que materiais finos possam ser transportados e armazenados de forma mais econômica. A recente preocupação ambiental, resultando em leis mais rígidas, além da necessidade de aproveitar economicamente os resíduos e as partículas finas geradas no beneficiamento de minérios fez com que a briquetagem voltasse a ser uma importante alternativa para aglomerar valor econômico. O objetivo deste trabalho foi aglomerar finos de calcário através da briquetagem (92% abaixo de 500# ou 25 µm gerados no processamento do mesmo, variando as dosagens de água (utilizada como agente aglomerante de 0; 5; 7,5; 10; 12,5 e 15%. O calcário, originário de Lagamar (MG, foi classificado quimicamente como dolomítico tipo D. Os briquetes foram submetidos a testes de queda a 30, 60, 90, 120 e 150 cm de altura. Os melhores resultados encontrados para ensaios de queda foram obtidos com 7,5% de umidade, com médias de 21 quedas para 30 cm e 10 quedas para 60 cm de altura. Tais resultados apresentaram-se favoráveis quando comparados à literatura, a qual cita que para briquetes sem cura, considera-se 3 quedas a 0,3 m como valor razoável.

    Full Text Available Abstract Background Blastocystis is a cosmopolitan protist parasite found in the human gastrointestinal tract and is highly prevalent in developing countries. Recent molecular studies have revealed extensive genetic diversity, which has been classified into different subtypes (STs based on sequence analysis of small subunit ribosomal RNA gene. Blastocystis is one of the most common fecal parasites in Brazil, but the diversity of subtypes remains unknown in the country. This study aimed to determine the distribution of Blastocystis STs in an urban community in Duque de Caxias, Rio de Janeiro, Brazil. Methods A total of 64 stool samples positive for Blastocystis in Pavlova’s medium were subtyped by PCR and sequenced using primers targeting the small subunit rRNA gene, in addition to phylogenetic analysis and subtype-specific PCR using sequence-tagged-site (STS primers. Results Endolimax nana (14%, Entamoeba complex (10.5%, Taenia sp. (0.6%, Trichuris trichiura (1.3% and Enterobius vermicularis (1.3% were detected in Blastocystis-positive samples. Of the 64 samples tested by PCR/DNA sequencing, 55 were identified as ST1 (42%, ST3 (49%, ST2 (7% and ST4 (2%, and the presence of mixed ST (ST1 + ST3 infection was detected in nine samples (14%. Conclusions DNA sequencing and phylogenetic analysis of Brazilian Blastocystis isolates identified four different subtypes. To our knowledge, this study provided the first genetic characterization of Blastocystis subtypes in an urban area of Rio de Janeiro, Brazil. We also identified ST4 for the first time in Brazil. Further studies are necessary to determine the distribution of STs across human populations in Rio de Janeiro.

    Uptake of uranium by higher fungi, such as mushroom is little elucidated. We have studied the interaction of uranium with Pleurotus sp. (a mushroom) in pure culture over a wide range of U concentration (50-3000 mg/L). The Pleurotus sp. was cultured in two different media. One was rice bran medium, and the other was agar (yeast extract, peptone and dextrose) medium. The uptake of uranium in Pleurotus sp. was examined by alpha ray autoradiography (A,A), X-ray fluorescence spectroscopy (XRF) and scanning microcopy (SEM) equipped with EDS. In the agar medium, the higher uranium concentration gave lower growth of mycelia, and no fruiting body was observed. In the rice bran medium, the fruiting body was grown at U concentrations up to 1000 mg/L. The AA and XRF analysis showed that uranium taken up in the fruiting body was below the detection limit. The SEM-EDS analysis indicated that U was distributed in the limited region and was not transported to the mycelia far from U containing medium. It is concluded that uranium affects the growth of Pleurotus sp., and little uranium is taken up by Pleurotus sp. during the growth of both mycelia and fruiting body. (author)

    Once introduced into the aquatic environment, many substances can bind or be adsorbed by organic particles in suspension. Depending on the river morphology and hydrological conditions, these particles in suspension containing the contaminants can be deposited along its course, becoming part of the bottom sediments, making them actual sinks and often a source of contamination for the water column and benthic organisms. In the assessment of water, sediment has been one of the most important indicators of the contamination levels in aquatic ecosystems, representing the deposition of contaminants in the environment that occurred over the years and even decades. The Tiete River cross the Sao Paulo state, however, in the metropolitan region of Sao Paulo, the river shows the most severe degradation. In the region of Salesopolis, the waters of the Tiete River are used for public supply, but across the city of Mogi das Cruzes the water quality decreases significantly. Considering the importance of the Tiete river and the sediment for the aquatic biota, this study aimed to evaluate the toxicity of the sediment at five points along the Tiete river, between the cities of Salesopolis and Suzano, Sao Paulo. Four sampling were carried out: two in the summer (rainy season) and two in winter (dry season). The whole sediment was assessed by acute and chronic toxicity tests with Hyalella azteca and Ceriodaphnia dubia, respectively, the elutriate was assessed by chronic toxicity test using C. dubia, while the porewater was evaluated by acute toxicity test with Vibrio fischeri. Samples of river water were also evaluated for chronic toxicity tests with C. dubia. The quantification of metals and hydrocarbons in sediment samples was also carried out in order to correlate the biological effects with the chemical contamination. The obtained results with the whole sediment test indicate Mogi das Cruzes and Suzano cities as the most toxic sites and also as the sites with the highest concentrations of heavy metals. The tests with aqueous phases (elutriate and porewater) indicated the site located in Biritiba-Mirim as the most problematic. High concentrations of hydrocarbons were also found in this site, as well as in another site located in Biritiba-Mirim. The Ponte Nova reservoir site showed toxicity in a few occasions, and it is the only site where high concentrations of contaminants was observed. The results showed a gradient of toxicity and contamination that increases according to the distance from the reservoir (P0) and with the proximity of populated and industrialized cities. (author)

    One hundred twenty-three of 300 blood samples (41%) taken from Rio Grande wild turkeys (Meleagris gallopavo intermedia) from three locations in southern Texas (Welder Wildlife Refuge, Chaparrosa Ranch, and Campo Alegre Ranch) and subinoculated into domestic broad-breasted white turkey poults were positive for a Plasmodium (Novyella) sp. Analysis of blood films from 350 turkeys revealed Haemoproteus meleagridis in 76% of the birds. A significantly greater mean parasite intensity was observed in birds from Welder Wildlife Refuge. Birds from the Campo Alegre Ranch exhibited a significantly higher prevalence of H. meleagridis than birds from Chaparrosa. The Plasmodium sp. was infective for canaries (Serinus canaria), bobwhites (Colinus virginianus), and ring-necked pheasants (Phasianus colchicus), but would not produce infection in white leghorn chickens (Gallus gallus) or Coturnix quail (Coturnix coturnix). Attempts to infect Culex tarsalis and C. pipiens pipiens were unsuccessful. Asexual erythrocytic synchrony was not observed when blood-induced infections were monitored in two domestic turkey poults every 4 hr for 72 hr. Exoerythrocytic stages were not found upon examination of impression smears and tissue samples taken from brain, liver, spleen, kidney, lung, and bone marrow. The Plasmodium sp. is most similar morphologically to three species in the subgenus Novyella, P. hexamerium, P. vaughani, and P. kempi. The most striking similarities are to P. hexamerium, and involve mean merozoite number, erythrocytic schizont location, and vertebrate host susceptibility. It differs from P. vaughani in being able to infect turkeys and in type of parasitized erythrocytes. Differences to P. kempi include mean merozoite number, and ability to infect pheasants, and its inability to develop inC. pipiens and C. tarsalis.

  16. SP2Bench: A SPARQL Performance Benchmark

    Science.gov (United States)

    Schmidt, Michael; Hornung, Thomas; Meier, Michael; Pinkel, Christoph; Lausen, Georg

    A meaningful analysis and comparison of both existing storage schemes for RDF data and evaluation approaches for SPARQL queries necessitates a comprehensive and universal benchmark platform. We present SP2Bench, a publicly available, language-specific performance benchmark for the SPARQL query language. SP2Bench is settled in the DBLP scenario and comprises a data generator for creating arbitrarily large DBLP-like documents and a set of carefully designed benchmark queries. The generated documents mirror vital key characteristics and social-world distributions encountered in the original DBLP data set, while the queries implement meaningful requests on top of this data, covering a variety of SPARQL operator constellations and RDF access patterns. In this chapter, we discuss requirements and desiderata for SPARQL benchmarks and present the SP2Bench framework, including its data generator, benchmark queries and performance metrics.

    Full Text Available SUMMARY American tegumentary leishmaniasis (ATL is an infectious disease caused by protozoa of the genus Leishmania, and transmitted by sandflies. In the state of Rio de Janeiro, almost all of the cases of American tegumentary leishmaniasis (ATL are caused by Leishmania (Viannia braziliensis, while cases of visceral leishmaniasis (VL are caused by Leishmania (Leishmania infantum chagasi. The resurgence of autochthonous VL cases in Rio de Janeiro is related to the geographic expansion of the vector Lutzomyia longipalpis and its ability to adapt to urban areas. We report the first case of leishmaniasis with exclusively cutaneous manifestations caused by L. (L. infantum chagasi in an urban area of Rio de Janeiro. An eighty-one-year-old woman presented three pleomorphic skin lesions that were not associated with systemic symptoms or visceromegalies. Multilocus enzyme electrophoresis identified L. (L. infantum chagasi, but direct smear and PCR of bone narrow were negative for Leishmania sp. (suggesting exclusively cutaneous involvement. We discuss the different dermatological presentations of viscerotropic leishmaniasis of the New and Old World, and the clinical and epidemiological importance of the case. Etiologic diagnosis of ATL based upon exclusive clinical criteria may lead to incorrect conclusions. We should be aware of the constant changes in epidemiological patterns related to leishmaniases.

  1. Modifications of Sp(2) covariant superfield quantization

    We propose a modification of the Sp(2) covariant superfield quantization to realize a superalgebra of generating operators isomorphic to the massless limit of the corresponding superalgebra of the osp(1,2) covariant formalism. The modified scheme ensures the compatibility of the superalgebra of generating operators with extended BRST symmetry without imposing restrictions eliminating superfield components from the quantum action. The formalism coincides with the Sp(2) covariant superfield scheme and with the massless limit of the osp(1,2) covariant quantization in particular cases of gauge-fixing and solutions of the quantum master equations.

    Application of Halobacterium sp. SP1(1) for the acceleration of fish sauce fermentation. Traditional fish sauce fermentation was mimicked using Halobacterium sp. SP1(1) as starter culture. Protease activity, peptide release and α-amino content (parameters used to monitor the progress of the fermentation) were high at day 10 in tests and day 20 in un-inoculated controls. The total protein and nitrogen contents were also high in tests compared with controls. The amino acid profile observed at the end of fermentation in experimental samples, when compared with the commercial sauce preparation, was found to be better with respect to flavour and aroma contributing amino acids as well as essential amino acid lysine. Microflora analysis of the final fish sauce revealed the absence of any nonhalophilic or halotolerant micro-organisms. The protease-producing halophilic isolates obtained from the fish sauce of eviscerated and uneviscerated controls were identified as Halobacterium sp. F1 and F2, respectively, by 16S rDNA sequence analysis. Exogenous augmentation of Halobacterium sp. SP1(1) accelerated the fish sauce fermentation process with an additive effect on the existing natural microflora present in the fish during fermentation. Halobacterium sp SP1(1), therefore, can be used as an important starter culture for accelerating the fish fermentation process, which is attributed to its extracellular protease. The present study is the first report on use of Halobacterium species as a starter culture for accelerating fish sauce fermentation. Use of halobacterial starter cultures may revolutionize the process in fish sauce industries by reducing the fermentation time and making the process more economical with improved nutritive value of product.

  8. Environmental impacts associated with Project Rio Blanco

    Alldredge, A.W.; Whicker, F.W.; Hanson, W.C.

    Project Rio Blanco, an experiment involving deep underground detonation of three 30-kton nuclear explosives designed to stimulate natural gas flow in geologic formations of low permeability, was conducted in western Colorado on 17 May 1973. Environmental impacts associated with this experiment were divided into three categories: radiation, ground motion, and conventional physical activities. Radiation and ground motion are unique to this type experiment while conventional activities would be associated with any type of resource development. The objective of observations made at Rio Blanco was to qualitatively and, where possible, quantitatively ascertain environmental impacts associated with the project. Observations indicated that ground motion and conventional activities appeared to cause the greatest impacts. Ground motion impacts were most severe within 2.4 km of the emplacement well (EW) and were predominantly associated with steep ravine and stream banks and rocky cliffs. Following the detonation, flow and turbidity had increased in a small stream adjacent to the EW. Animals receiving deleterious impacts were those associated with stream banks, cliffs and burrows. No mortality or injury was observed in any large animals. (U.S.)

    1998-11-25

    Surfactant protein A (SP-A) binding to bovine alveolar macrophages was examined in order to characterize SP-A binding proteins on the cell surface and to isolate putative receptors from these cells that could be obtained in large amounts. Human SP-A, unlabeled or labeled with gold particles, was bound to freshly isolated macrophages and analyzed with ELISA or the transmission electron microscope. Binding of SP-A was inhibited by Ca2+ chelation, by an excess of unlabeled SP-A, or by the presence of 20 mg/ml mannan. We conclude that bovine alveolar macrophages expose binding sites for SP-A that are specific and that depend on Ca2+ and on mannose residues. For isolation of SP-A receptors with homologous SP-A as ligand we isolated SP-A from bovine lung lavage. SDS-PAGE analysis of the purified SP-A showed a protein of 32-36 kDa. Functional integrity of the protein was demonstrated. Bovine SP-A bound to Dynabeads was used to isolate SP-A binding proteins. From the fractionated and blotted proteins of the receptor preparation two proteins bound SP-A in a Ca2+-dependent manner, a 40-kDa protein showing mannose dependency and a 210-kDa protein, showing no mannose sensitivity.

    Spectra of five isolates (LMG 28358 T , LMG 29879 T , LMG 29880 T , LMG 28359 T and R-53705) obtained from gut samples of wild bumblebees of Bombus pascuorum, Bombus lapidarius and Bombus terrestris were grouped into four MALDI-TOF MS clusters. RAPD analysis revealed an identical DNA fingerprint for LMG 28359 T and R-53705 which also grouped in the same MALDI-TOF MS cluster, while different DNA fingerprints were obtained for the other isolates. Comparative 16S rRNA gene sequence analysis of the four different strains identified Gilliamella apicola NCIMB 14804 T as nearest neighbour species. Average nucleotide identity values of draft genome sequences of the four isolates and of G. apicola NCIMB 14804 T were below the 96% threshold value for species delineation and all four strains and G. apicola NCIMB 14804 T were phenotypically distinct. Together, the draft genome sequences and phylogenetic and phenotypic data indicate that the four strains represent four novel Gilliamella species for which we propose the names Gilliamella intestini sp. nov., with LMG 28358 T as the type strain, Gilliamella bombicola sp. nov., with LMG 28359 T as the type strain, Gilliamella bombi sp. nov., with LMG 29879 T as the type strain and Gilliamella mensalis sp. nov., with LMG 29880 T as the type strain.

    Recent rDNA sequencing of 25 isolates from a previous study, during which limonene-utilizing yeasts were isolated from monoterpene-rich environments by using 1,4-disubstituted cyclohexanes as sole carbon sources, led to the identification of four hitherto unknown Rhodotorula species. Analyses of the 26S rDNA D1/D2 region as well as the internal transcribed spacer (ITS) domain indicated that two isolates (CBS 8499(T) and CBS 10736) were identical and were closely related to Rhodotorula cycloclastica, a previously described limonene-utilizing yeast. These novel isolates differed from known yeast species and could be distinguished from R. cycloclastica by standard physiological tests. The other three isolates represent three novel Rhodotorula species, closely related to Sporobolomyces magnisporus. These three species could also be distinguished from other Rhodotorula species by standard physiological tests. Based on these results, we suggest that the new isolates represent novel species, for which the names Rhodotorula eucalyptica sp. nov. (type strain CBS 8499(T)  = NRRL Y-48408(T)), Rhodotorula pini sp. nov. (type strain CBS 10735(T)  = NRRL Y-48410(T)), Rhodotorula bloemfonteinensis sp. nov. (type strain CBS 8598(T)  = NRRL Y-48407(T)) and Rhodotorula orientis sp. nov. (type strain CBS 8594(T)  = NRRL Y-48719(T)) are proposed. R. eucalyptica and R. pini can also utilize limonene.

Sob esta perspectiva, A Cerimônia do Adeus (1981, que relata os dez últimos anos de vida de Sartre, apresenta uma estrutura narrativa curiosa: propõe-se como um diário, mas do outro, pois a narradora tenta anular-se em favor da reconstrução de um retrato de Sartre. No entanto, por injunção desta proposta, inviável, o texto acaba transformando-se num ponto de convergência de vários gêneros narrativos, tendo em vista o caráter múltiplo de personalidade do biografado. E este personalizado trabalho narrativo, à revelia da própria autora, acarreta o processo inverso: o texto transforma-se num retrato de Simone. Consuma-se, desta forma, no próprio corpo do texto, o movimento de sedução, em que ambos, homem e mulher, realizam-se como sujeitos necessários Um ao Outro.L'oeuvre de Simone de Beauvoir est marquée par son caractère fortemente autobiographique, aussi bien que par le dialogue constante avec son partenaire Sartre.

    The N/P ratio of wastewater can vary greatly and directly affect algal growth and nutrient removal process. Three benthic filamentous algae species Cladophora sp., Klebsormidium sp. and Pseudanabaena sp. were isolated from a periphyton bioreactor and cultured under laboratory conditions on varying N/P ratios to determine their ability to remove nitrate and phosphorus. The N/P ratio significantly influenced the algal growth and phosphorus uptake process. Appropriate N/P ratios for nitrogen and phosphorus removal were 5-15, 7-10 and 7-20 for Cladophora sp., Klebsormidium sp. and Pseudanabaena sp., respectively. Within these respective ranges, Cladophora sp. had the highest biomass production, while Pseudanabaena sp. had the highest nitrogen and phosphorus contents. This study indicated that Cladophora sp. had a high capacity of removing phosphorus from wastewaters of low N/P ratio, and Pseudanabaena sp. was highly suitable for removing nitrogen from wastewaters with high N/P ratio.

    Three different chromium-resistant microorganisms (Pseudomonas aeruginosa, Micrococcus sp., and Ochrobactrum sp.) were tested with regard to their EPS production at different pH levels, temperatures, Cr(VI) concentrations, and incubation periods. The optimum pH level was 7 for P. aeruginosa and Micrococcus sp., while it was 8 for Ochrobactrum sp. according to the highest EPS amount at 100 mg/L Cr(VI) concentration. The highest production of EPSs by the three bacteria was obtained under different environmental conditions. P. aeruginosa produced the highest EPS (863.3 mg/L) after incubation for 96 h on media with 50 mg/L Cr(VI) at 20 degrees C, Micrococcus sp. gave the highest yield (444.6 mg/L) after incubation for 72 h on media with 100 mg/L Cr(VI) at the same temperature, and Ochrobactrum sp. had the highest production (430.5 mg/L) on media with 150 mg/L Cr(VI) at 30 degrees C at the end of 48 h of incubation.

    1980-01-01

    Multifrequency airborne radar image data of SP Mountain [Official name of feature (U.S. Geological Survey, 1970)] and SP flow (and vicinity) in north-central Arizona were obtained in diverse viewing directions and direct and cross-polarization, then compared with surface and aerial photography, LANDSAT multispectral scanner data, airborne thermal infrared imagery, surface geology, and surface roughness statistics. The extremely blocky, basaltic andesite of SP flow is significantly brighter on direct-polarization K-band (0.9-cm wavelength) images than on cross-polarized images taken simultaneously. Conversely, for the longer wavelength (25 cm) L-band radar images, the cross-polarization image returns from SP flow are brighter than the direct-polarized image. This effect is explained by multiple scattering and the strong wavelength dependence of polarization effects caused by the rectilinear basaltic andesite scatters. Two distinct types of surface relief on SP flow, one extremely blocky, the other subdued, are found to be clearly discriminated on the visible and thermal wavelength images but are separable only on the longer wavelength L-band radar image data. The inability of the K- and X- (3-cm wavelength) band radars to portray the differences in roughness between the two SP flow surface units is attributed to the radar frequency dependence of the surface-relief scale, which, described as the Rayleigh criterion, represents the transition between quasispecular and primarily diffuse backscatter. ?? 1980.

    Few data are available on the dynamic of radon in the air for tropical climate conditions. The strong influence of the climatological characteristics on the transport of gases and particulates in air makes not adequate the use of data obtained at regions with different climate. Outdoor and indoor measurements of radon equilibrium equivalent concentrations (EEC) have been done for one-year period in Rio de Janeiro. Continuous measurements were performed using a radon monitor with an alpha spectrometry detector. Pluviometric index, temperature and humidity were registered. The paper presents the long term behaviour of outdoor radon equilibrium equivalent concentration results, their correlation with temperature and the influence of the pluviometric index. Maximum values were obtained during winter and minimum in summer, strongly influenced by the rain. A strong inverse correlation with temperature was found. (author)

  9. Rio Blanco: nuclear operations and chimney reentry

    Woodruff, W.R.; Guido, R.S.

    1975-01-01

    Rio Blanco was the third experiment in the U.S. Atomic Energy Commission's Plowshare Program to develop technology to stimulate gas production from geologic formations not conducive to production by conventional means. The project was sponsored by CER Geonuclear Corporation, with the Lawrence Livermore Laboratory providing the explosives and several technical programs, such as spall measurement. Three nuclear explosives specifically designed for this application were detonated simultaneously in a minimum-diameter emplacement well using many commercially available but established-reliability components. The explosive system performed properly under extreme temperature and pressure conditions. Emplacement and stemming operations were designed with the aim of simplifying both the emplacement and reentry and fully containing the detonation products. An integrated command and control system was used with communication to all three explosives through a single coaxial cable. Reentry and the initial production testing are completed. To date 98 million standard ft 3 of chimney gas have been produced. (auth)

    Full Text Available Encholirium Lutzii is distinguished from the majority of species by its branched inflorescence. Only E. horridum L. B. Smith and rarely E. spectabile Martius exhibit this character, but have much larger flowers than E. Lutzii and stout floral axes. Also the wing of the seed in E. horridum is very long-caudate. We feel that it is particularly appropriate to dedicate this new species to Dr. Adolpho Lutz because of his great discoveries in the biological relationships of the Bromeliaceae.

    The effects of Ag–Cu ions on the microbiologically induced corrosion of galvanized steel in the presence of Desulfovibrio sp. and Desulfosporosinus sp. were investigated. The corrosion behavior of galvanized steel was analyzed by potentiodynamic polarization and electrochemical impedance spectroscopy. The biofilm, corrosion products and Ag–Cu ions on the surfaces were investigated by using scanning electron microscopy, energy dispersive X-ray spectrometry and elemental mapping. The biofilm layer formed by the Desulfovibrio sp. was stable covering the all surface of galvanized steel coupons, while that by Desulfosporosinus sp. was intermittent, highly porous and heterogeneous. It was found that both of the sulfate reducing bacteria species accelerated corrosion of the galvanized steel. However, it was detected that Desulfosporosinus sp. was more corrosive for galvanized steel than Desulfovibrio sp. Scanning electron microscopy images showed that Desulfovibrio sp. and Desulfosporosinus sp. in biofilm clustered into patches on the galvanized steel surface when the culture contained toxic Ag–Cu ions. The ions affected the growth of the sulfate reducing bacteria strains in different ways and hence the corrosion behaviors. It was observed that the Ag–Cu ions affected negatively growth of Desulfosporosinus sp. especially after 24 h of exposure leading to a decrease in the corrosion rate of galvanized steel. However, Desulfovibrio sp. showed more corrosive effect in the presence of the ions according to the ions-free culture. Energy dispersive X-ray spectrometry analysis showed that corrosion products on the surfaces were mainly composed of Zn, S, Na, O and P. - Highlights: • Galvanized steel was corroded by Desulfosporosinus sp. and Desulfovibrio sp. • Desulfosporosinus sp. is more corrosive than Desulfovibrio sp. • The Ag–Cu ions affected corrosion behavior of Desulfosporosinus sp. and Desulfovibrio sp. on galvanized steel.

    Graphitization occurs during the long-term service of a diamond-like carbon (DLC) modified artificial joint. Then, DLC wear debris, which are carbon particles with different sp{sup 2}/sp{sup 3} ratios and sizes ranging from the nano- to micro-meter scale produced. In this paper, to promote the application of DLC coating for artificial joint modification, the cytotoxicity of DLC debris (nano-carbon particles, NCs) with different sp{sup 2}/sp{sup 3} ratios was studied. The microstructure and physical characteristics of NCs with different sp{sup 2}/sp{sup 3} ratios were investigated by Raman spectroscopy, X-ray photoelectron spectroscopy (XPS), Transmission Electron Microscope (TEM) and Dynamic Light Scattering (DLS). Meanwhile, osteoblasts and macrophages were applied to characterize the cytotoxicity of the NCs. In vitro cytotoxicity assay results indicated that cells incubated with NCs of different sp{sup 2}/sp{sup 3} ratios had greater osteogenic capacity, and these particles caused a weaker immune response in comparison with CoCrMo particles. Taken together, the results indicated that NCs with different sp{sup 2}/sp{sup 3} ratios presented a good cytocompatibility than CoCrMo particles. But no significant differences were observed among NCs with different sp{sup 2}/sp{sup 3} ratios. The better cytocompatibility of NCs is mainly attributable to their surface charge. - Highlights: • NCs with different sp{sup 2}/sp{sup 3} ratios have been successfully prepared by annealing treatment. • NCs with different sp{sup 2}/sp{sup 3} ratios show good osteogenic capacity and lower immune response. • The good cytocompatibility of NCs is mainly dependent on its surface charge.

    Full Text Available A reference inventory of prehistoric marine mollusks from the Rio das Ostras region was created based on an excavation carried out at the Sambaqui da Tarioba shellmound. Patterns of richness and biogeography were studied, and the representativeness of bivalve and gastropod diversities found at this archaeological site were inferred. A total of 47 taxa belonging to 28 families, most of which from unconsolidated substrates, was identified. The shellmound species composition does not differ from the present-day composition. All recorded species are characteristic of a wide transition zone between the south of the states of Espírito Santo (21°S and Rio Grande do Sul (32°S. Thus, the data show little evidence of evolution in the composition, richness,and biodiversity distribution patterns of mollusks in the Rio das Ostras region. Likewise, a reconstitution of the paleoenvironment from the functional characteristics of the shellmound species indicates that the locality's geomorphology and climate remained largely unchanged in the last 4,000 years BP.

    Research highlights: → Sp1 zinc fingers themselves interact with importin α. → Sp1 zinc finger domains play an essential role as a nuclear localization signal. → Sp1 can be transported into the nucleus in an importin-dependent manner. -- Abstract: Transcription factor Sp1 is localized in the nucleus and regulates the expression of many cellular genes, but the nuclear transport mechanism of Sp1 is not well understood. In this study, we revealed that GST-fused Sp1 protein bound to endogenous importin α in HeLa cells via the Sp1 zinc finger domains, which comprise the DNA binding domain of Sp1. It was found that the Sp1 zinc finger domains directly interacted with a wide range of importin α including the armadillo (arm) repeat domain and the C-terminal acidic domain. Furthermore, it turned out that all three zinc fingers of Sp1 are essential for binding to importin α. Taken together, these results suggest that the Sp1 zinc finger domains play an essential role as a NLS and Sp1 can be transported into the nucleus in an importin-dependent manner even though it possesses no classical NLSs.

    Carbon allotropes with distinct sp, sp2, and sp3 hybridization possess various different properties. Here, a novel all-sp3 hybridized tetragonal carbon, namely the P carbon, was predicted by the evolutionary particle swarm structural search. It demonstrated a low density among all-sp3 carbons, due to the corresponding distinctive microporous structure. P carbon is thermodynamically stable than the known C60 and could be formed through the single-walled carbon nanotubes (SWCNTs) compression. P carbon is a direct bandgap semiconductor displaying a strong and superhard nature. The unique combination of electrical and mechanical properties constitutes P carbon a potential superhard material for semiconductor industrial fields.

    Full Text Available Neste artigo consideramos os problemas ambientais globais dentro do conceito de limiares planetários, em convergência com os últimos avanços das ciências naturais. Nesse contexto, nosso objetivo é explorar o papel do Brasil na governança do espaço de operação seguro para a humanidade, avaliando como o país complementa o enorme capital ambiental físico que possui com ações políticas específicas orientadas para uma economia verde de baixo carbono (EVBC, tanto no âmbito doméstico quanto no internacional. Para atingir essa meta, em primeiro lugar discutimos conceitualmente a economia verde de baixo carbono como paradigma de desenvolvimento compatível com um espaço de operação seguro para a humanidade; em segundo lugar, analisamos a Rio+20 pelo prisma da governança global dos limiares planetários e pela atuação brasileira na Cúpula; e finalmente fazemos um diagnóstico da situação do Brasil em relação ao novo paradigma de desenvolvimento. Como conclusões da análise, destacamos a crescente distância entre a aceleração dos problemas da interdependência - especialmente a definição de um espaço seguro de operação para a humanidade - e os mecanismos globais de governança existentes, derivada de um sistema internacional bloqueado e dominado por forças conservadoras. O resultado frustrante da Rio+20 é evidência clara dessa defasagem. Nessa dinâmica, o Brasil tem o potencial para ser um ator central da governança dos limiares planetários, por seu vasto capital ambiental físico. No entanto, o mínimo avanço da EVBC no país degrada essa capacidade de agência, e o torna uma potência ambiental subdesenvolvida (underachiever environmental power.

Eighty-one (91% specimens of S. setapinnis were parasitized by one or more metazoan species. Twenty-one species of parasites were collected: 8 digeneans, 3 monogeneans, 2 cestodes, 5 nematodes, and 3 copepods. The endoparasites (digeneans, cestodes, and nematodes were 74.1% of total number of parasite specimens collected. The monogenean Pseudomazocraes selene (Hargis, 1957 was the most dominant species with the highest prevalence in the parasite community of S. setapinnis. The metazoan parasites of this host species showed the typical aggregated pattern of distribution. Only one parasite species (Acanthocolpoides pauloi Travassos, Freitas & Buhrnheim, 1955 showed positive correlation between the host total length and parasite abundance in S. setapinnis. Caligus robustus Bassett-Smith, 1898, P. selene, and Terranova sp. demonstrated positive correlation between the host total length and prevalence. Larvae of Terranova sp. showed influence of the host sex on its prevalence. A pair of ectoparasite species, P. selene-C. robustus, exhibited positive covariation between their abundances. Two pairs of endoparasite species, L. microstomum-P. merus and A. pauloi-P. merus showed significant covariation among their abundances; and the pair Terranova sp.-Raphidascaris sp. had positive co-ocorrence and covariation in the infracommunities of S. setapinnis. Like the parasite communities of the other carangid fishes from Rio de Janeiro, the parasite community of S. setapinnis is apparently only a slightly ordered species complex, characterized by dominance of endoparasite species.

    The formation and maintenance of the apical ectodermal ridge (AER) is critical for the outgrowth and patterning of the vertebrate limb. The induction of the AER is a complex process that relies on integrated interactions among the Fgf, Wnt, and Bmp signaling pathways that operate within the ectoderm and between the ectoderm and the mesoderm of the early limb bud. The transcription factors Sp6 and Sp8 are expressed in the limb ectoderm and AER during limb development. Sp6 mutant mice display a mild syndactyly phenotype while Sp8 mutants exhibit severe limb truncations. Both mutants show defects in AER maturation and in dorsal-ventral patterning. To gain further insights into the role Sp6 and Sp8 play in limb development, we have produced mice lacking both Sp6 and Sp8 activity in the limb ectoderm. Remarkably, the elimination or significant reduction in Sp6;Sp8 gene dosage leads to tetra-amelia; initial budding occurs, but neither Fgf8 nor En1 are activated. Mutants bearing a single functional allele of Sp8 (Sp6−/−;Sp8+/−) exhibit a split-hand/foot malformation phenotype with double dorsal digit tips probably due to an irregular and immature AER that is not maintained in the center of the bud and on the abnormal expansion of Wnt7a expression to the ventral ectoderm. Our data are compatible with Sp6 and Sp8 working together and in a dose-dependent manner as indispensable mediators of Wnt/βcatenin and Bmp signaling in the limb ectoderm. We suggest that the function of these factors links proximal-distal and dorsal-ventral patterning. PMID:25166858

Results:This isolate was able to remove up to 37.12% of resorcinol from contaminated water. Reusability experiments had confirmed the biodegradation process which produced seven intermediate compounds. These intermediates were characterized by gas chromatography-mass spectroscopy technique. The products of resorcinol biodegradation were apparently 1, 4-cyclohexadiene, nonadecene, 2-heptadecanone, 1-isopropyl-2-methoxy-4-methylbenzene, hexadecanoic acid, 9-octadecenoic acid, phenol and 5-methyl-2-(1-methylethyl). Conclusions: The findings revealed thatPseudomonas sp. is able to degrade resorcinol. Because of being an indigenous organism, this isolate is more compatible with the climate of the northwest region of Iran and possibly will be used for degradation of other similar aromatic compounds.

    This paper discusses the SP-100 Space Reactor Power System which is being developed by GE, under contract to the U.S. Department of Energy, to provide electrical power in the range of 10's to 100's of kW. The system represents an enabling technology for a wide variety of earth orbital and interplanetary science missions, nuclear electric propulsion (NEP) stages, and lunar/Mars surface power for the Space Exploration Initiative (SEI). The technology and design is now at a state of readiness to support the definition of early flight demonstration missions. Of particular importance is that SP-100 meets the demanding U.S. safety performance, reliability and life requirements. The system is scalable and flexible and can be configured to provide 10's to 100's of kWe without repeating development work and can meet DoD goals for an early, low-power demonstration flight in the 1996-1997 time frame

Através de fontes primárias e análise documental, a pesquisa desenvolve interpretações sobre as influências paternas de caráter moral, cultural, intelectual e profissional que marcaram a primeira geração da família Palmério no Brasil e, particularmente, condicionaram as experiências que mais tarde seriam ressignificadas na obra literária e na trajetória pessoal de Mário Palmério. Notamos que as permanentes viagens a trabalho do pai e as suas diversas atividades profissionais favoreceram uma consciência familiar das particularidades da região. Essa experiência favoreceu a criação de vínculos econômicos, políticos e afetivos com a cultura regional e estimulou nos filhos um profundo conhecimento histórico e geográfico do Oeste mineiro. Além disso, o pai parece ter exercido uma profunda influência sobre os filhos no que diz respeito ao gosto pela política regional. O artigo desenvolve a hipótese de que todas essas experiências foram elementos presentes na formação de Mário Palmério e, mais tarde, apareceriam de modo explícito em sua literatura marcada pela descrição da natureza, do cotidiano e das intrigas políticas regionalistas. Palavras-chave: Regionalismo; Literatura regionalista; Literatura mineira; Mário Palmério; Vila dos Confins; Chapadão do Bugre.

We propose an ab initio study of such carbon-only materials, by computing their structure and stability, as well as their electronic, vibrational and magnetic properties. We adopt a fair compromise of microscopic realism with a certain level of idealization in the model configurations, and predict a number of properties susceptible to comparison with experiment.

    1995-01-01

    For more than a decade, Jet Propulsion Labortory and Los Alamos have managed a multi-agency funded effort to develop a space reactor power system. This SP-100 Program has developed technologies required for space power systems that can be implemented in the industrial and commercial sectors to improve competitiveness in the global economy. Initial steps taken to transfer this technology from the laboratories to industrial and commercial entities within United States include: (1) identifying specific technologies having commercial potential; (2) distributing information describing the identified technologies and interacting with interested commercial and industrial entities to develop application-specific details and requirements; and (3) providing a technological data base that leads to transfer of technology or the forming of teaming arrangements to accomplish the transfer by tailoring the technology to meet application-specific requirements. SP-100 technologies having commercial potential encompass fabrication processes, devices, and components. Examples: a process for bonding refractory metals to graphite, a device to sense the position of an actuator and a component to enable rotating machines to operate without supplying lubrication (self-lubricating ball bearing). Shortly after the NASA Regional Technology Transfer Centers widely disseminated information covering SP-100 technologies, over one hundred expressions of interest were received, which indicate that there is a large potential benefit in transferring SP-100 technology. Interactions with industrial and commercial entities have identified a substantial need for creating teaming arrangements involving the interested entity and personnel from laboratories and their contractors, who have the knowledge and ability to tailor the technology to meet application-specific requirements. copyright 1995 American Institute of Physics

    The production of cellulolytic enzymes (β-exoglucanase, β-endoglucanase and β-glucosidase) by Penicillium sp. on three different media in liquid shake culture conditions was compared. The organism exhibited relatively highest activity of endoglucanase among three enzymes measured at 7-day interval during the course of its growth on Czapek-Dox medium supplemented with 0.5 % (w/v) cellulose. Cellulose at 0.5 %, lactose at 0.5 %, sawdust at 0.5 %, yeast extract at 0.2 % as a nitrogen source, pH 5.0 and 30 °C temperature were found to be optimal for growth and cellulase production by Penicillium sp. Yields of Fpase, CMCase and β-glucosidase, attained on optimized medium with Penicillium sp. were 8.7, 25 and 9.52 U/ml, respectively with increment of 9.2, 5.9 and 43.8-folds over titers of the respective enzyme on unoptimised medium. Cellulase of the fungal culture with the ratio of β-glucosidase to Fpase greater than one will hold potential for biotechnological applications.

    The biosorption of radionuclide 241 Am from solutions by Candida sp., and the influences of experimental conditions on the adsorption were studied. The results showed that the adsorption equilibrium was achieved within 4h and the optimum pH=2. No significant differences on 241 Am biosorption were observed at 10-45 degree C, or challenged with Au 3+ or Ag + , even 1500 times or 4500 times over 241 Am, respectively. The adsorption rate could reach 97.8% by dry Candida sp. of 0.82 g/L in 241 Am solutions (pH=2) of 5.6-111 MBq/L (44.04-873.0 μg/L) (C 0 ), with maximum adsorption capacity (W) of 63.5 MBq/g (501.8 μg/g), implying that the removal of 241 Am by Candida sp. from solutions was feasible. The relationship between activities (C 0 ) and adsorption capacities (W) of 241 Am indicated that the biosorption process could be described by Langmuir adsorption isotherm

    As an important radioisotope in nuclear industry and other fields, americium-241 is one of the most serious contamination concerns duo to its high toxicity and long half-life. In this experiment, the biosorption of 241 Am from solution by Candida sp., and the effects of various experimental conditions on the adsorption were investigated. The preliminary results showed that the adsorption of 241 Am by Candida sp. was efficient. 241 Am could be removed by Candida sp. of 0.82 g/L (dry weight) from 241 Am solutions of 5.6-111 MBq/L (44.3-877.2 μg/L)(C 0 ), with maximum adsorption rate (R) of 98% and maximum adsorption capacities (W) of 63.5 MBq/g biomass (dry weight) (501.8 μg/g). The biosorption equilibrium was achieved within 4 hour and the optimum pH was pH = 2. No significant differences on 241 Am adsorption were observed at 10 C-45 C, or in solutions containing Au 3+ or Ag + , even 1500 times or 4500 times above the 241 Am concentration, respectively. The relationship between concentrations and adsorption capacities of 241 Am indicated the biosorption process should be described by a Langmuir adsorption isotherm. (orig.)

    Two species of the genus Borrelia , Borrelia bissettiae sp. nov. and Borrelia californiensis sp. nov., were first described by Postic and co-workers on the basis of genetic analyses of several loci. Multilocus sequence analysis of eight housekeeping loci confirmed that these two Borrelia genomospecies are distinct members of the Borrelia burgdorferi sensu lato complex. B. bissettiae sp. nov. was initially described in transmission cycles involving Neotoma fuscipes wood rats and Ixodes pacificus ticks in California, and Neotoma mexicana and Ixodes spinipalpis in Colorado. The preferred host of B. californiensis sp. nov. appears to be the California kangaroo rat, Dipodomys californicus ; Ixodes jellisoni , I. spinipalipis and I. pacificus ticks are naturally infected with it. Thus, the ecological associations of the two genomospecies and their genetic distance from all other known Borrelia genomospecies species justify their description as separate genomospecies: B. bissettiae sp. nov. (type strain DN127 T  = DSM 17990 T  =  CIP 109136 T ) and B. californiensis (type strain CA446 T  = DSM 17989 T  = ATCC BAA-2689 T ).

  13. Rio Blanco massive hydraulic fracture: project definition

    International Nuclear Information System (INIS)

    1976-01-01

    A recent Federal Power Commission feasibility study assessed the possibility of economically producing gas from three Rocky Mountain basins. These basins have potentially productive horizons 2,000 to 4,000 feet thick containing an estimated total of 600 trillion cubic feet of gas in place. However, the producing sands are of such low permeability and heterogeneity that conventional methods have failed to develop these basins economically. The Natural Gas Technology Task Force, responsible for preparing the referenced feasibility study, determined that, if effective well stimulation methods for these basins can be developed, it might be possible to recover 40 to 50 percent of the gas in place. The Task Force pointed out two possible underground fracturing methods: Nuclear explosive fracturing, and massive hydraulic fracturing. They argued that once technical viability has been demonstrated, and with adequate economic incentives, there should be no reason why one or even both of these approaches could not be employed, thus making a major contribution toward correcting the energy deficiency of the Nation. A joint Government-industry demonstration program has been proposed to test the relative effectiveness of massive hydraulic fracturing of the same formation and producing horizons that were stimulated by the Rio Blanco nuclear project

    1992-10-01

    In reviewing the work packages included in the Rio Earth's Summit Agenda 21, intended as an activities guideline for international cooperation to ensure environmental protection with sustainable growth for all nations, this paper points out the areas which present the greatest obstacles in the establishment of common accords and discusses the directions being taken to surmount these obstacles. A major obstacle concerns uncertaindes in specifying limits on carbon dioxide emissions and their effects on world climate. Another concerns suitable methods to help finance effective technology transfer to developing countries. With regard to the former problem, a 'no regret' approach has been proposed to limit current C02 reduction interventions to those levels which, in all certainty, would not incur any future regrets once scientific knowledge has advanced enough to allow more accurate assessments of greenhouse gas/climate change inter-relationships. With regard to the latter problem, attempts are being made to reduce possible negative impacts on the petroleum industry due to energy surcharges suggested as a source of funding for technology transfer/environmental protection programs.

    2003-01-01

    Nanoscale transformation of electronic states by highly charged ion (HCI) impact on graphite surfaces is described. The high potential energy of slow HCI, which induces multiple emission of electrons from the surface, provides a strong modification of the electronic states of the local area upon graphite surfaces. The HCI impact and the subsequent surface treatment either by electron injection from a scanning tunneling microscopy tip or by He-Cd laser irradiation induce a localized transition from sp 2 to sp 3 hybridization in graphite, resulting in the formation of nanoscale diamond-like structures (nanodiamond) at the impact region. From Raman spectroscopic measurements on sp 2 related peaks, it is found that the HCI irradiation creates vacancy complexes in contrast to ions having a lower charge state, which generate single vacancies. It is of interest that a single impact of HCI creates one nanodiamond structure, suggesting potential applications of HCI in nanoscale material processing

    Full Text Available This research aimed to describe the frequency of parasites in stool samples in the environment of Ilha da Marambaia, Rio de Janeiro, Brazil. One hundred and five stool samples were collected and processed by the coproparasitological techniques ethyl acetate sedimentation and centrifuge-flotation using saturated sugar solution. Parasites were detected in 81.9% of the samples, hookworm being the most prevalent, followed by Trichuris vulpis. Ascaris sp. eggs were also found. A high level of evolutive forms of parasites with public health risk was found in stool samples of the environment studied. We propose that health education programs, allied to an improvement of human and animal health care, must be employed to reduce the environmental contamination.

On the basis of 16S rRNA gene sequence analysis, the three strains were found to belong to the genus Burkholderia, showing the closest phylogenetic similarity to Burkholderia diazotrophica JPY461(T) (97.2-97.7%); the similarity between the three sequences ranged from 98.3 to 98.7%. Additionally, the three strains formed a distinct group in phylogenetic trees based on the housekeeping genes recA and gyrB. The predominant ubiquinone was Q-8, the major fatty acids were C16 : 0 and C17  : 0 cyclo and the DNA G+C content of the novel isolates was 61.6-64.4 mol%. DNA-DNA relatedness among the three strains and the type strains of the closest species of the genus Burkholderia was less than 50%. On the basis of 16S rRNA, recA and gyrB gene sequence similarities, chemotaxonomic and phenotypic data, the three strains represent three novel species within the genus Burkholderia, for which the names Burkholderia humisilvae sp. nov. (type strain Y-12(T)= KACC 17601(T) = NBRC 109933(T) = NCAIM B 02543(T)), Burkholderia solisilvae sp. nov. (type strain Y-47(T) = KACC 17602(T)= NBRC 109934(T) = NCAIM B 02539(T)) and Burkholderia rhizosphaerae sp. nov. (type strain WR43(T) = KACC 17603(T) = NBRC 109935(T) = NCAIM B 02541(T)) are proposed.

    The Rio Claro and Piracununga formations cover extensive areas of the Paulista Peripheral Depression, dominantly in the region of Rio Claro and Piracununga cities. These units lie over the Corumbatai and Piramboia formations, exhibiting discordant contacts. The Rio Claro and Piracununga formations are composed of fine to medium sand facies, showing local cross-stratifications and parallel beddings with thin interbeddings of mud and gravel. These sands were dated by the Thermoluminescence Method, which indicated they were from the Pleistocene age. The oldest age (745,000 years BP) was found in deposits of the Rio Claro Formation; the other ages varied from 400,000 years BP to 145,000 years BP, for both formations. The youngest age (15,000 years BP - close to Pleistocene/ Holocene limit) was found in colluvial deposits, which rest on the Piracununga Formation. (author)

  11. Role of surfactant protein A (SP-A)/lipid interactions for SP-A functions in the lung.

    Science.gov (United States)

    Casals, C

    2001-01-01

    Surfactant protein A (SP-A), an oligomeric glycoprotein, is a member of a group of proteins named collectins that contain collagen-like and Ca(2+)-dependent carbohydrate recognition domains. SP-A interacts with a broad range of amphipathic lipids (glycerophospholipids, sphingophospholipids, glycosphingolipids, lipid A, and lipoglycans) that are present in surfactant or microbial membranes. This review summarizes SP-A/lipid interaction studies regarding the lipid system used (i.e., phospholipid vesicles, phospholipid monolayers, and lipids immobilized on silica or adsorbed on a solid support). The effect of calcium, ionic strength, and pH on the binding of SP-A to lipids and the subsequent lipid aggregation process is discussed. Current evidence suggests that hydrophobic-binding forces are involved in the peripherical association of SP-A to membranes. It is also proposed that fluid and liquid-ordered phase coexistence in surfactant membranes might favor partition of SP-A into those membranes. The binding of SP-A to surfactant membranes containing hydrophobic surfactant peptides makes possible the formation of a membrane reservoir in the alveolar fluid that is protected by SP-A against inactivation and improves the rate of surfactant film formation. In addition, the interaction of SP-A with membranes might enhance the affinity of SP-A for terminal carbohydrates of glycolipids or glycoproteins on the surface of invading microorganisms.

  18. The SP Theory of Intelligence: An Overview

    Directory of Open Access Journals (Sweden)

    J Gerard Wolff

    2013-08-01

    Full Text Available This article is an overview of the SP theory of intelligence, which aims to simplify and integrate concepts across artificial intelligence, mainstream computing and human perception and cognition, with information compression as a unifying theme. It is conceived of as a brain-like system that receives "New" information and stores some or all of it in compressed form as "Old" information; and it is realised in the form of a computer model, a first version of the SP machine. The matching and unification of patterns and the concept of multiple alignment are central ideas. Using heuristic techniques, the system builds multiple alignments that are "good" in terms of information compression. For each multiple alignment, probabilities may be calculated for associated inferences. Unsupervised learning is done by deriving new structures from partial matches between patterns and via heuristic search for sets of structures that are "good" in terms of information compression. These are normally ones that people judge to be "natural", in accordance with the "DONSVIC" principle—the discovery of natural structures via information compression. The SP theory provides an interpretation for concepts and phenomena in several other areas, including "computing", aspects of mathematics and logic, the representation of knowledge, natural language processing, pattern recognition, several kinds of reasoning, information storage and retrieval, planning and problem solving, information compression, neuroscience and human perception and cognition. Examples include the parsing and production of language with discontinuous dependencies in syntax, pattern recognition at multiple levels of abstraction and its integration with part-whole relations, nonmonotonic reasoning and reasoning with default values, reasoning in Bayesian networks, including "explaining away", causal diagnosis, and the solving of a geometric analogy problem.

    This paper reports on a design trade study of the SP-100 heat rejection subsystem (HRSS) which was made. A system code was used to evaluate the sensitivity of the HRSS mass and performance to changes. Variations in heat pipe diameter and cross-section, fin length and thickness, armor thickness, and overall configuration and materials were evaluated. The analysis indicates that the minimum system mass occurs for the case with many small diameter heat pipes, with ducting that maximizes the fraction of the heat pipe evaporator perimeter in contract with it

    Full Text Available Este artigo teve como objetivo analisar o itinerário dos usuários que tiveram acesso a medicamentos via judicial no estado do Amazonas, Brasil. Trata-se de estudo qualitativo, prospectivo, baseado em dados coletados por meio de entrevistas semiestruturadas com usuários que receberam medicamentos via mandado judicial. A judicialização na saúde mostrou-se um fator agregador ao reconhecimento dos direitos e da cidadania pelos usuários que, na sua trajetória de vida, acabaram adquirindo um grande aprendizado sobre formas de enfrentar a falta de acesso aos medicamentos. Conclui-se que a relação entre o sujeito e o Estado permanece desigual, e o direito à saúde se deu na dimensão individual e restritiva, desconsiderando a dimensão coletiva e a concepção de cidadania.

    Full Text Available We studied some parameters of the parasitism by the mite Hannemania sp. on the endemic frog Hylodes phyllodes in the Atlantic Forest of Ilha Grande (Rio de Janeiro State, Brazil. Prevalence, mean abundance, mean intensity and total intensity of infestation, body regions infected, and host sexual differences in parasitism rate of the larvae of Hannemania sp. on individuals of H. phyllodes were assessed. Prevalence was 86.5% (N = 37; total of 1,745 larvae of Hannemania sp for male hosts and 91.7% (N =12; total of 330 larvae for female hosts, with no significant difference between the sexes. Overall prevalence of Hannemania sp. on H. phyllodes was 87.7%. Mean intensity of infestation in males (54.5 ± 42.5; range 1-173 larvae was higher than in females (29.9 ± 47.6; range 1-166. We conclude that the rates of intensity, abundance, and prevalence of Hannemania larvae parasitizing Hylodes phyllodes at Ilha Grande were considerably high, suggesting that this species of anuran constitutes a relevant host for this mite species to complete its lifecycle in the area. Differences between males and females in infestation rates probably reflect their differential use of space in the forest.

    Full Text Available Manganese is a contaminant in the wastewaters produced by Brazilian mining operations, and the removal of the metal is notoriously difficult because of the high stability of the Mn(II ion in aqueous solutions. To explore a biological approach for removing excessive amounts of aqueous Mn(II, we investigated the potential of Mn(II oxidation by both consortium and bacterial isolates from a Brazilian manganese mine. A bacterial consortium was able to remove 99.7% of the Mn(II. A phylogenetic analysis of isolates demonstrated that the predominant microorganisms were members of Stenotrophomonas, Bacillus, and Lysinibacillus genera. Mn(II removal rates between 58.5% and 70.9% were observed for Bacillus sp. and Stenotrophomonas sp. while the Lysinibacillus isolate 13P removes 82.7%. The catalytic oxidation of Mn(II mediated by multicopper oxidase was not properly detected; however, in all of the experiments, a significant increase in the pH of the culture medium was detected. No aggregates inside the cells grown for a week were found by electronic microscopy. Nevertheless, an energy-dispersive X-ray spectroscopy of the isolates revealed the presence of manganese in Stenotrophomonas sp. and Lysinibacillus sp. grown in K medium. These results suggest that members of Stenotrophomonas and Lysinibacillus genera were able to remove Mn(II by a nonenzymatic pathway.

    Biodiesel has several advantages over solar. Compared to solar, biodiesel has more eco-friendly characteristic and produces lower greenhouse gas emissions. Biodiesel that is made from animal fats can be produced from fish oil, while other alternative sources from vegetable oils are seaweed Kappaphycus alvarezii and Gracilaria sp. Waste tuna oil (Thunnus sp.) in Indonesia is commonly a side product of tuna canning industries known as tuna precook oil; on the other hand, seaweed Gracilaria sp. and Kappaphycus alvarezii are commonly found in Indonesia's seas. Seaweed waste that was used in the present study was 100 kg and in wet condition, and the waste oil was 10 liter. The seaweed was extracted with soxhletation method that used n-hexane as the solvent. To produce biodiesel, trans esterification was performed on the seaweed oil that was obtained from the soxhletation process and waste tuna oil. Biodiesel manufactured from seaweed K. alvarezii obtained the best score in flash point, freezing point, and viscosity test. However, according to level of manufacturing efficiency, biodiesel from waste tuna oil is more efficient and relatively easier compared to biodiesel from waste K. alvarezii and Gracilaria sp.

    The recovery of toxic metal compounds is a deep concern in all industries. Hexavalent chromium is particularly worrying because of its toxic influence on human health. In this paper, biodegradation of hexavalent chromium (Cr+6) present in wastewater has been studied using two different bacterial strains; Pseudomonas sp. and Bacillus sp. A chemostat (with and without recycle of cells) with 10 L liquid culture volume was used to study the substrate and the biomass cell concentrations with time. Also, the degree of substrate conversion was studied by the varying the dilution rate as an independent parameter. The dilution rate (ratio of feed flow rate to the culture volume) was varied by varying the feed volumetric rate from 110-170 mL/h for inlet hexavalent chromium concentrations of 70 mg/dm3. The results show that a chemostat with recycle gives a better performance in terms of substrate conversion than a chemostat without a recycle. Moreover, the degree of substrate conversion decreases as the dilution rate is increased. Also, Bacillus sp. was found to give higher conversions compared to pseudomonas sp.

    Full Text Available ABSTRACT To evaluate the adhesive efficiency on the union of glued joints in a particular temperature and humidity conditions for a specified time the adhesive must be submitted to specific load tests, such as shear in the glue line. The objective of this study was to evaluate the shear strength in the glue line of Eucalyptus sp and Pinus sp.woods. Five adhesives (castor oil, sodium silicate, modified silicate, , PVA and resorcinol-formaldehyde, three weights (150 g/m2, 200 g/m2, and 250 g/m2 and two species (Eucalyptus sp. and Pinus sp. of wood were used. Twelve specimens were obtained from each repetition per treatment, corresponding to 108 specimens that were conditioned at a temperature of 23 ± 1°C and relative humidity of 50 ± 2%. The interaction between the weight and type of adhesive was significant for the shear strength in the glue line of eucalyptus wood. However, no interaction between the weight and the adhesive was found for pinus, only the isolated from the adhesive effect. Chemical bonds originated in the polymerization of resorcinol-formaldehyde adhesives and castor bi-component conferred upon these adhesives the greatest resistance in the glue line. Castor and resorcinol-formaldehyde adhesives showed the highest shear strength values in the line of glue and wood failure. Castor adhesive presented satisfactory performance for bonding of eucalyptus and pine woods.

    Regarded as being a potentially effective tool to combat oil pollution, bioremediation involves mineralization, i.e., the conversion of complex hydrocarbons into harmless CO{sub 2} and water by action of microorganisms. Therefore, in achieving optimum effectiveness from the application of these products on crude oil in local environments, the capability of the bacteria to mineralize hydrocarbons was evaluated. The microbial laboratory testing of mineralization on local oil degraders involved, first, isolation of bacteria found at a port located on the west coast of Peninsular Malaysia. Subsequently, these bacteria were identified by means of Biomereux`s API 20E and 20 NE systems and later screened by their growth on a Malaysian crude oil. Selected strains of Pseudomonas sp. and Achromabacter sp. were then exposed individually to a similar crude oil in a mineralization unit and monitored for 16 days for release of CO{sub 2}. Pseudomonas paucimobilis was found to produce more CO{sub 2} than Achromobacter sp. When tested under similar conditions, mixed populations of these two taxa produced more CO{sub 2} than that produced by any individual strain. Effective bioremediation of local crude in Malaysian waters can therefore be achieved from biochemically developed Pseudomonas sp. strains.

    Full Text Available Abstract The increasingly urban nature of the population has led many people to choose independent pets, such as cats. This situation has also made it possible for these animals to be abandoned, thus increasing the numbers of cats on the streets and in shelters. These animals can act as a source of infection for other hosts. Between 2014 and 2015, the frequency of gastrointestinal parasites in captive and stray cats in the municipality of Rio de Janeiro was analyzed. Ninety-one fecal samples were collected from captive cats and 172 from stray cats. Centrifugal sedimentation and flotation techniques were used. The frequency of parasites among the stray cats was 77.3%, and this was significantly higher than the frequency observed in captive cats (49.5%. Helminths were detected more frequently, and hookworms were the parasites most detected. Toxocara cati, Cystoisospora sp. and Dipylidium caninum were also detected. No statistical difference in the frequency of parasites was observed between the sexes among the captive cats. However, among the stray cats, males (85.5% presented higher positivity than females (71.8%. The high frequency of hookworms, which are the agent for “cutaneous larva migrans” in humans, shows the need to control parasitic infections among the cats studied.

O método utilizado, de Análise Pragmática da Narrativa Jornalística, permitiu identificar as estratégias de subjetivação do texto, pelas quais o repórter alcança efeitos poéticos e induz seus leitores a diversos tipos e graus de comoção. O trabalho analisa reportagem sobre a tragédia ambiental ocorrida em Mariana (MG em 2016 e aponta os recursos poéticos em uso para concluir que linguagem, estrutura de texto e personagens são o tripé sobre o qual se constitui o jornalismo literário praticado pelo Brio. Este trabalho é resultado de projeto conduzido no âmbito do Grupo de Pesquisa Produção de Conteúdo, do Mestrado Profissional em Produção Jornalística e Mercado da ESPM-SP.

    Full Text Available Estudos sobre novos adesivos ou resinas para colagem de madeira e derivados estão sendo realizados com a intenção de diminuir o impacto ambiental sem alterar suas propriedades. Por este motivo, novas formulações de adesivos PVA (Acetato de Polivinila vêm sendo desenvolvidas. Este trabalho testou a utilização deste adesivo na produção de compensado de Eucalyptus sp. e Pinus sp., com tempo e temperatura de prensagem, respectivamente, de 10 minutos e90°C. Foram realizados os ensaios físicos de densidade, teor de umidade e absorção, e os ensaios mecânicos de flexão estática e de resistência ao cisalhamento na linha de cola, todos de acordo com as normas ABNT. Obtiveram-se bons resultados com relação à resistência ao cisalhamento na linha de cola, a qual foi superior para os adesivos PVA, se comparados com compensados produzidos com ureia-formaldeído e o fenol-formaldeído, enquanto que os resultados de MOE e MOR apresentaram-se inferiores em ambos os casos.

    Thymol is present in the essential oils from herbs and spices, such as thyme. It is produced by these plant species as a chemical defense against phytopathogenic microorganisms. Therefore, this compound has attracted great attention in food industry, i.e., it has been used as a natural preservative in foods such as cheese to prevent fungal growth. Previous studies concerning the biotransformation of nerol by Penicillium sp. and microbial transformation of citral by sporulated surface cultures method (SSCM) of Penicillium digitatum have been reported. The objective of this research was to study the pathway involved during biotransformation of citral by Penicillium sp. using two methods. The culture preparation was done using different microbial methods and incubation periods to obtain Penicillium for citral biotransformation. The biotransformation products were identified by gas chromatography (GC) and gas chromatography/mass spectroscopy (GC/MS). A comparison of the two methods showed that SSCM was more effective, its major products were thymol (21.5 %), geranial (18.6 %) and nerol (13.7 %). LM produced only one compound — thymol — with a low efficiency.

    Two Gram-negative, rod-shaped bacteria were isolated from agricultural soils in Córdoba province in central Argentina. Their 16S rRNA gene sequences demonstrated that they belong to the genus Burkholderia, with Burkholderia zhejiangensis as most closely related formally named species; this relationship was confirmed through comparative gyrB sequence analysis. Whole-cell fatty acid analysis supported their assignment to the genus Burkholderia. Burkholderia sp. strain YI23, for which a whole-genome sequence is available, represents the same taxon, as demonstrated by its highly similar 16S rRNA (100% similarity) and gyrB (99.1-99.7%) gene sequences. The results of DNA-DNA hybridization experiments and physiological and biochemical characterization further substantiated the genotypic and phenotypic distinctiveness of the Argentinian soil isolates, for which the name Burkholderia cordobensis sp. nov. is proposed, with strain MMP81(T) ( = LMG 27620(T) = CCUG 64368(T)) as the type strain. © 2014 IUMS.

    Full Text Available Background. Deqi sensation is a complex but an important component for acupuncture effect. In this study, we tried to observe the relationship between Deqi and skin temperature changes and whether there was some relativity between Deqi and needle stimulations on cold congealing and dysmenorrhea rat model. Thirty-two female Sprague Dawley (SD rats were randomly divided into four groups (Saline Control Group, Model Group, Group A with strong stimulation, and Group B with small stimulation. Group A and Group B were performed with different stimulations. We found that, compared with saline control group, model group, and Group B, Group A showed that the skin temperature changes on right acupoint SP6 and SP10 increased significantly at 5 min–10 min interval. The skin temperature changes on left SP6 decreased at instant–5 min interval. The skin temperature changes on right SP10 decreased significantly at instant–5 min interval and 10 min–20 min interval. Thermogenic action along Spleen Meridian of Foot Greater Yin was manifested as simultaneous skin temperature increase on right SP6 and SP10 at 5 min–10 min interval after needling SP6, which was helpful to illustrate the relationship between the characteristic of Deqi and needle stimulations.

    Full Text Available Entre as abelhas eussociais, dois gêneros apresentam estratégia de vida cleptobiótica, obtendo recursos alimentares de ninhos de outras abelhas ao invés de coletá-los em flores. Entre as espécies atacadas existe um gradiente de suscetibilidade ao roubo variando desde espécies vulneráveis até altamente resistentes. Neste trabalho nós descrevemos um ataque de Lestrimelitta rufipes a um ninho de Scaptotrigona sp. em um meliponário na Amazônia central (Amazonas, Brazil. O ninho atacado foi transferido para um meliponário com espécies resistentes (Duckeola ghilianii e Melipona fulva e as interações foram descritas. As abelhas resistentes contra-atacaram e afugentaram as ladras protegendo o ninho de Scaptotrigona sp.. A presença de comportamento defensivo em gêneros não proximamente relacionados sugere que ele tenha evoluído mais de uma vez entre os Meliponini. Considerando o comportamento descrito, sugerimos a criação de espécies nativas resistentes em meliponários de regiões onde elas forem nativas, devido ao potencial que elas tem na proteção.Among eusocial bees, two genera evolved a cleptobiotic life strategy, stealing food resources from other bee nest instead of collecting it from flowers. Under natural conditions there is a gradient of strategies against robbing, from more susceptible to highly resistant species. In this work, we describe one attack of the robber bee Lestrimelitta rufipes to a nest of Scaptotrigona sp. in the Amazon Rain Forest (Amazonas, Brazil. The attacked nest was introduced in a beekeeping area with bees already known to be resistant to cleptobiosis. The resident bees (Duckeola ghilianii and Melipona fulva counter-attacked the robber bees and successfully protect the Scaptotrigona sp. nest. The presence of the defensive behaviour in unrelated genera suggests it evolved many times in social bees. Based on the protective behaviour described here, we suggest that in order to reduce the damage caused

Foram testadas 35 estirpes de Rhizobium sp., isoladas de quinze diferentes espécies de leguminosas tropicais, e incluído um tratamento de inoculação com solo previamente cultivado com amendoim. Das 35 estirpes testadas, doze formaram nódulos e, entre essas, sete foram eficientes fixadoras de nitrogênio. Das doze estirpes que nodularam, sete foram isoladas de leguminosas da tribo Hedysareae (à qual pertence o género Arachis e, destas, apenas quatro foram eficientes fixadoras de nitrogênio. O peso e o número de nódulos não se mostraram como critérios adequados para avaliação da eficiência.An experiment was carried out in Leonard jars, in the greenhouse, with nitrogen-free nutrient solution to test the efficiency of 35 strains of rhizobia isolated from 15 species of tropical legumes. Twelve of the tested strains were capable of nodule formation in peanut. Seven of those strains were isolated from the trible Hedysareae, which includes the genus Arachis. Only four of the rhizobia strains with inducing nodulation were effective. Dry weight and number of nodules were not good criteria for evaluating effectiveness.

    Full Text Available Streptomyces sp. US 24 and Streptomyces sp. TN 58, two strains producing interesting bioactive molecules, were successfully transformed using E. coli ET12567 (pUZ8002, as a conjugal donor, carrying the integrative plasmid pSET152. For the Streptomyces sp. US 24 strain, two copies of this plasmid were tandemly integrated in the chromosome, whereas for Streptomyces sp. TN 58, the integration was in single copy at the attB site. Plasmid pSET152 was inherited every time for all analysed Streptomyces sp. US 24 and Streptomyces sp. TN 58 exconjugants under nonselective conditions. The growth, morphological differentiation, and active molecules production of all studied pSET152 integrated exconjugants were identical to those of wild type strains. Consequently, conjugal transfer using pSET152 integration system is a suitable means of genes transfer and expression for both studied strains. To validate the above gene transfer system, the glucose isomerase gene (xylA from Streptomyces sp. SK was expressed in strain Streptomyces sp. TN 58. Obtained results indicated that heterologous glucose isomerase could be expressed and folded effectively. Glucose isomerase activity of the constructed TN 58 recombinant strain is of about eighteenfold higher than that of the Streptomyces sp. SK strain. Such results are certainly of importance due to the potential use of improved strains in biotechnological process for the production of high-fructose syrup from starch.

    Full Text Available Este artigo apresenta um modelo evolucionário setorial de simulação que combina microfundamentos neo-schumpeterianos e pós-keynesianos e expõe alguns resultados preliminares das primeiras simulações. Estes resultados apontam, quanto a distintas condições do ambiente de mercado: o efeito positivo da taxa de crescimento da produtividade na fronteira tecnológica sobre a concentração de mercado; o efeito ambíguo do aprendizado, capaz de produzir um lock-in de firmas inovadoras pioneiras em tecnologias que se tornam eventualmente obsoletas; o efeito "anti-seletivo" de taxas de juros muito elevadas, endividando e prejudicando o esforço de investimento e o sucesso competitivo das inovadoras em benefício das imitadoras. Quanto à simulação das estratégias de preços, constatou-se: a maior seletividade de estratégias em que as firmas inovadoras dão mais peso ao mark-up desejado, gerando maior concentração de mercado, efeito que é atenuado pelo crescimento da demanda e pelo aprendizado; a importância, para a sobrevivência de empresas menos inovadoras, do feedback do desempenho competitivo sobre o mark-up desejado e o efetivo, aumentando a adaptabilidade das empresas às condições de seleção do mercado.This paper presents a sectoral evolutionary simulation model combining neo-Schumpeterian and Post-Keynesian microfoundations, and exhibits some preliminary results. As to different market environment conditions, the simulations suggest: a positive effect of productivity growth of the technological frontier on market concentration; an ambiguous result of "learning by doing", from which innovation leaders may be found "locked in" new technologies that eventually become obsolete; a "counter-selective" effect of very high interest rates which may increase innovators indebtedness to the extent of impairing their investment efforts and competitive success as compared to some imitators.

A amostragem da vegetação foi feita pelo método de parcelas, sendo registrado o diâmetro à altura do peito (DAP e a altura dos indivíduos > 1 m de altura. Os resultados indicaram que a floresta plantada apresenta menores valores de DAP médio e área basal, e maior densidade de troncos em relação à floresta natural. A distribuição de indivíduos por classes de altura e a distribuição de troncos por classes diamétricas mostraram que a floresta plantada é mais jovem. Laguncularia racemosa e Rhizophora mangle ocorreram em ambas as florestas, enquanto Avicennia schaueriana foi registrada apenas na floresta plantada. Laguncularia racemosa apresentou maior dominância e densidade relativa em todos os sítios analisados, provavelmente, por ser característica de locais com menor influência marinha e pelo fato do estuário ter sido alterado por perturbações antrópicas.

    Full Text Available The córrego Paulicéia is a direct tributary of the rio Mogi-Guaçu, located in Santa Rita do Passa Quatro, State of São Paulo, Southeastern Brazil. This stream runs inside a savannah-like (cerrado environment and it associated vegetation. Biological and ecomorphological aspects of its fish community were studied in three stretches of the stream, denominated herein as the upper, middle and lower courses. The fish fauna recorded in this study consisted of 15 species, belonging to five orders and nine families, based in a total of 715 collected individuals representing 1,450 kg of biomass. The most important abiotic factors related to the occurrence and distribution of the fish fauna were the substrate, current speed, and presence or absence of riparian vegetation. The analysis of 336 stomach contents of 13 species demonstrated that 65% of food items are autochthonous, 32% allochthonous, and 3% are of unknown origin. Four alimentary guilds could be identified, based on the predominant food items: omnivores with tendency to insectivory - Astyanax paranae, A. fasciatus and Piabina argentea; larvivores - Corydoras difluviatilis, Cetopsorhamdia iheringi, Phenacorhamdia tenebrosa, Characidium gomesi, Eigenmannia virescens, and Rhamdia quelen; periphyton feeders - Hisonotus sp., Hypostomus ancistroides and Synbranchus marmoratus; and piscivore - Hoplias malabaricus. Reproductions data are presented for Astyanax altiparanae and Hisontus sp. Three ecomorphological groups could be established, based on swimming, feeding, and microhabitat strategies: nektonic (A. fasciatus, A. paranae, Bryconamericus stramineus, P. argentea, H. malabaricus and Phallotorynus jucundus, benthic (C. gomesi, P. tenebrosa, C. iheringi, R. quelen, C. difluviatilis, H. ancistroides and Hisonotus sp., and necktobenthic (E. virescens and S. marmoratus.

    Biofilm is a microbial derived sessile community characterized by cells that are irreversibly attached to a substratum or interface to each other, embedded in a matrix of extracellular polymeric substances that they have produced. Bacillus sp. was used as biofilm model in this study. The purpose of this study is to determine the effect of Garlic solution in term of ratio of water and Garlic solution (W/G) and ratio of Garlic solution to Bacillus sp. (GS/B) on Bacillus sp removal. Garlic solution was used to remove Bacillus sp. In this study, Garlic solution was prepared by crushing the garlic and mixed it with water. the Garlic solution was added into Bacillus sp. mixture and mixed well. The mixture then was spread on nutrient agar. The Bacillus sp. weight on agar plate was measured by using dry weight measurement method. In this study, initially Garlic solution volume and Garlic solution concentration were studied using one factor at time (OFAT). Later two-level-factorial analysis was done to determine the most contributing factor in Bacillus sp. removal. Design Expert software (Version 7) was used to construct experimental table where all the factors were randomized. Bacilus sp removal was ranging between 42.13% to 99.6%. The analysis of the results showed that at W/G of 1:1, Bacillus sp. removal increased when more Garlic solution was added to Bacillus sp. Effect of Garlic solution to Bacillus sp. will be understood which in turn may be beneficial for the industrial purpose.

    Full Text Available This paper analyses the availability of public resources for Brazilian cultural policies. The study comes from an intrinsic relation between culture and politics, between ways of seeing, living and thinking the world and its political consequences, identifying the umbilical link between culture and hegemony in classes societies. Analyses laws based on tax waiver, specifically patronage, which presented annual values similar to the Ministry of Culture budget itself; and Living Culture Program, which represented a significant change in State intervention in cultural themes. It concludes that incentive laws mean losses in democratic control and also reproduce regional inequalities, with higher resources concentration in São Paulo and Rio de Janeiro, acting as marketing tool for large corporations. Living Culture Program, on the other hand, presents a more equality public resources distribution, but is still contemplated with a derisive budget compared to incentive laws.

    Full Text Available As práticas de letramento literário da escola brasileira voltam-se majoritariamente para textos em suporte impresso, embora parte significativa da produção literária contemporânea em língua portuguesa venha sendo feita em suporte eletrônico ou digital. Tal disjunção se deve, entre outros fatores, à predominância de obras canônicas no currículo escolar, à natureza impressa do livro didático e a um entendimento restrito do que seja o texto literário. Por outro lado, assistimos ao uso crescente de aparelhos celulares e smartphones em sala de aula, raramente articulado ao processo de ensino-aprendizagem, ainda que esses dispositivos possam integrar práticas de letramento literário na esfera digital. No presente artigo, discutem-se questões teórico-metodológicas acerca do uso, em sala de aula, de celulares e smartphones para o trabalho com um gênero literário emergente: a Twitteratura. Da página à tela, do ponto ao pixel, novos entendimentos do literário podem ser introduzidos no currículo escolar, propiciando uma compreensão mais ampla sobre as relações sobredeterminantes entre linguagem, sociedade e tecnologia.

    Full Text Available Abstract Background Surfactant protein D (SP-D deficient mice develop emphysema-like pathology associated with focal accumulations of foamy alveolar macrophages, an excess of surfactant phospholipids in the alveolar space and both hypertrophy and hyperplasia of alveolar type II cells. These findings are associated with a chronic inflammatory state. Treatment of SP-D deficient mice with a truncated recombinant fragment of human SP-D (rfhSP-D has been shown to decrease the lipidosis and alveolar macrophage accumulation as well as production of proinflammatory chemokines. The aim of this study was to investigate if rfhSP-D treatment reduces the structural abnormalities in parenchymal architecture and type II cells characteristic of SP-D deficiency. Methods SP-D knock-out mice, aged 3 weeks, 6 weeks and 9 weeks were treated with rfhSP-D for 9, 6 and 3 weeks, respectively. All mice were sacrificed at age 12 weeks and compared to both PBS treated SP-D deficient and wild-type groups. Lung structure was quantified by design-based stereology at the light and electron microscopic level. Emphasis was put on quantification of emphysema, type II cell changes and intracellular surfactant. Data were analysed with two sided non-parametric Mann-Whitney U-test. Main Results After 3 weeks of treatment, alveolar number was higher and mean alveolar size was smaller compared to saline-treated SP-D knock-out controls. There was no significant difference concerning these indices of pulmonary emphysema within rfhSP-D treated groups. Type II cell number and size were smaller as a consequence of treatment. The total volume of lamellar bodies per type II cell and per lung was smaller after 6 weeks of treatment. Conclusion Treatment of SP-D deficient mice with rfhSP-D leads to a reduction in the degree of emphysema and a correction of type II cell hyperplasia and hypertrophy. This supports the concept that rfhSP-D might become a therapeutic option in diseases that are

    The rose (Rosa sp.) petals can be dried after 2 days at about 30degC reaching an equilibrium moisture content after 16 h using the solar wire basket dryer. The initial moisture content (wet wt basis) and final moisture content (dry wt basis), determined by the Dean-Stark toluene were 65.7 and 25.2% respectively. The intensity of the rose red coloured pigment (pelargonidin) decreased by a factor of 2.5 after drying. The pelargonidin ethanoic extract as an acid-base indicator, has a K{sub 4} value of 1 x 10{sup -4} mol 1{sup -1} and pH of end point 4 and imbibed on filter paper and allowed to air dry for 5 min showed excellent properties as acid-based test tapes.

    1966-01-01

    Sarcocystis sp. obtained from wild populations of grackles, Quiscalus quiscula (Linn.), were examined to clarify the effect of the parasite on the host. Electron micrographs are presented to show areas of muscle destruction adjacent to the parasite which appear to be mechanically produced by the parasite. The microtubules within the villus-like projections of the cyst suggest that their possible function is absorptive and/or conductive with regard to the production of a toxin or the conveyance of nutritive material to the developing cells. The proposed function of submembranous filaments and their relation to the conoid is discussed. Similarities in the ultrastructure to Toxoplasma and other protozoa tend to negate the relegation of Sarcocystis to the fungi and further emphasize its protozoan nature.

    A strain of Serratia sp. showed intracellular electron-transparent inclusion bodies when incubated in the presence of citrate and glycerol 2-phosphate without nitrogen source following pre-growth under carbon-limitation in continuous culture. About 1.3 mmol citrate were consumed per 450 mg biomass, giving a calculated yield of maximally 55% of stored material per g of biomass dry wt. The inclusion bodies were stained with Sudan Black and Nile Red (NR), suggesting a lipid material, which was confirmed as polyhydroxybutyrate (PHB) by analysis of molecular fragments by GC and by FTIR spectroscopy of isolated bio-PHB in comparison with reference material. Multi-parameter flow cytometry in conjunction with NR fluorescence, and electron microscopy, showed that not all cells contained heavy PHB bodies, suggesting the potential for increasing the overall yield. The economic attractiveness is enhanced by the co-production of nanoscale hydroxyapatite (HA), a possible high-value precursor for bone replacement materials.

    1985-01-01

    This paper reports on methods for analyzing fuel designs proposed for the thermionic and thermoelectric concepts for SP-100 application. The proposed fuel design for the thermionic concept consisted of fully-enriched oxide fuel clad in chemical vapor deposition (CVD) tungsten, which also served as the emitter for the thermionic fuel element (TFE). The fuel density was 95% of theoretical with the linear heat rate flattened radially by removing fuel from the center of the fuel pellet. The fuel inner diameter varied from approx.0.45 in. at the core center to zero at the edge of the core. The as-fabricated gap between fuel and emitter was 10 mils radial. The emitter thickness was 80 mils, and the outer diameter was 1.099 in. The LIFE-4 code was used for evaluation of this concept after extensive review of the code and development of a procedure that corrects certain deficiencies noted in analysis of several tests

    Six new polyacetylenic alcohols, termed strongylotriols A and B; pellynols J, K, and L; and isopellynol A, together with three known polyacetylenic alcohols, pellynols A, B, and C were isolated from the marine sponges Petrosia sp., and Halichondria sp. collected in Okinawa, Japan. Their planer structures were determined based on 2D-NMR and mass spectrometric analysis of the degraded products by RuCl3 oxidation. The absolute stereochemistry of isolates was examined by their Mosher's esters. The strongylotriols were found to be optically pure compounds, whereas the pellynols are diastereomeric mixtures at the C-6 position. Proliferation experiments using the HeLa and K562 cell lines suggested that the essential structural units for activity are the "hexa-2,4-diyn-1,6-diol" and "pent-1-en-4-yn-3-ol" on the termini.

O Sistema Único de Saúde, cujas deretrizes preconizam a atenção universal e eqüânime, determina a relevância desta temática dentro do campo da avaliação dos serviços de saúde. Assim, foram estudados dois ambulatórios de pediatria de um hospital universitário, um geral e outro de uma subespecialiadade (pneumologia, comparando os usuários quanto ao acesso. MÉTODO: Foram aplicados 221 questionários entre clientes de ambos os ambulatórios de pediatria com o objetivo de se estudar e comparar variáveis socioeconômicas, procedência, acesso aos referidos ambulatórios e outros serviços de saúde. RESULTADOS: Evidenciou-se grande dificuldade de locomoção dos pacientes, a maioria dos quais são encaminhados por serviços de saúde locais. Dos pacientes atendidos 40% não receberam nenhum atendimento anteriormente à sua chegada ao hospital, fato que decorre principalmente de seu baixo nível socioeconômico, que os torna dependentes exclusivamente dos serviços públicos de saúde. A comparação entre os dois ambulatórios mostra que os pacientes do ambulatório de especialidade têm melhor nível socioeconômico e são menos dependentes dos serviços públicos, configurando desta forma uma situação de ineqüidade. CONCLUSÕES: É apontado o melhor nível socioeconômico dos usuários da especialidade bem como questões organizacionais do próprio serviço como os responsáveis pela iniqüidade verificada.

    The Rio Dulce National Park is one of Guatemala's major environmental assets. The park contains the remaining remnants of an eastern Guatemalan tropical rainforest which has good but fast deteriorating value for the development of the ecotourism industry. The governmenial objective for the region as stated in the Master Plan for the park is ecotourism development and protection of biodiversity. The decisions to be made concerning the long-term, sustainable use of the natural resources of the Rio Dulce region appear to be directed by existing environmental laws and the Rio Dulce Master Plan. However, the wording of these instruments is ambiguous and lacks specific definitions and criteria for making necessary determinations. This, in combination with lack of enforcement in the region, has led to extensive disparity in interpretation of the laws and uncontrolled, conflicting actions by individuals and organizations.

    Two different nematodes were isolated from the bark of Albizia lebbeck trees; one from insect infested and another from noninfested, healthy tree. Based on the biological, morphological, and molecular evidences, the nematodes are described as Deladenus albizicus n. sp. and D. processus n. sp. (Nematoda: Hexatylina). Deladenus albizicus n. sp., isolated from insect-infested tree, multiplied on the fungus Nigrospora oryzae. Myceliophagous females of this nematode reproduced by parthenogenesis and spermathecae were indistinct. Infective females, readily produced in the cultures, are dorsally curved. Only one type of males containing small-sized sperms in their genital tracts were produced in the culture. Myceliophagous females: L = 0.75 to 1.71 mm, a = 32.3 to 50.8, b = 9.3 to 11.2, b' = 5.2 to 7.3, c = 27.2 to 35.6, V = 91.0 to 93.3, c' = 2.0 to 2.9, stylet = 11 to 12 µm, excretory pore in the region of median pharyngeal bulb, 43 to 47 µm anterior to hemizonid. Deladenus processus n. sp., isolated from bark of healthy A. lebbeck tree, was cultured on Alternaria alternata. Myceliophagous females reproduced by amphimixis and their spermathecae contained rounded sperms. Infective females were never produced, even in old cultures. Myceliophagous females: L = 0.76 to 0.99 mm, a = 34 to 49, b = 13.3 to 17.7, b' = 3.8 to 5.8, c = 19.6 to 22.8, V = 92.2 to 93.5, c' = 2.7 to 3.5, stylet = 6 to 7 µm, excretory pore in the proximity of hemizonid, tail conoid, tapering from both sides to a long pointed central process. It is proposed to classify Deladenus species in three groups: durus, siricidicola, and laricis groups based on female and spermatogonia dimorphism, mode of reproduction, and insect parasitism.

    Bats are potential reservoirs of many vector-borne bacterial pathogens. The aim of the present study was to detect species of Anaplasma, Ehrlichia, Neorickettsia, Rickettsia, Borrelia and Bartonella in Brazilian free-tailed bats (Tadarida brasiliensis, Molossidae) from Buenos Aires city, Argentina. Between 2012 and 2013, 61 T. brasiliensis from urban areas of Buenos Aires city were studied. The samples were molecularly screened by PCR and sequencing. Five bats (8.2%) were positive to Neorickettsia risticii, one (1.6%) was positive to Rickettsia sp. and three bats (4.9%) to Bartonella sp. For molecular characterization, the positive samples were subjected to amplification and sequencing of a fragment of p51 gene for N. risticii, a fragment of citrate synthase gene (gltA) for Rickettsia genus and a fragment of gltA for Bartonella genus. Phylogenetic tree was constructed using the maximum-likelihood method. Phylogenetic analysis of N. risticii detect in our study revealed that it relates to findings in the USA West Coast; Rickettsia sp. detected is phylogenetically within R. bellii group, which also includes many other Rickettsia endosymbionts of insects; and Bartonella sp. found is related to various Bartonella spp. described in Vespertilionidae bats, which are phylogenetically related to Molossidae. Our results are in accordance to previous findings, which demonstrate that insectivorous bats could be infected with vector-borne bacteria representing a potential risk to public health. Future research is necessary to clarify the circulation of these pathogens in bats from Buenos Aires. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Three bacterial strains identified as Klebsiella sp. M3, Achromobacter sp. M6 and Rhodococcus sp. M2 were isolated by soil enrichment with endosulfan followed by shake flask enrichment technique. They were efficiently degrading endosulfan in the NSM (non sulfur medium) broth. Degradation of endosulfan was faster with the cell free extract of bacterial cells grown in the sulfur deficient medium (NSM) supplemented with endosulfan than that of nutrient rich medium (Luria Bertani). In the cell free extract of NSM supplemented with endosulfan as sole sulfur source, a unique band was visualized on SDS-PAGE but not with magnesium sulfate as the sole sulfur source in NSM and LB with endosulfan. Expression of a unique polypeptide band was speculated to be induced by endosulfan under sulfur starved condition. These unique polypeptide bands were identified as OmpK35 protein, sulfate binding protein and outer membrane porin protein, respectively, in Klebsiella sp. M3, Achromobacter sp. M6 and Rhodococcus sp. M2. Endosulfan showed dose dependent negative effect on total RNA yield of bacterial strains in nutrient rich medium. Absence of plasmid DNA indicated the presence of endosulfan metabolizing gene on genomic DNA. Copyright © 2013 Elsevier B.V. All rights reserved.

    Today, with the massive application of lithium ion batteries (LIBs) in the portable devices and electric vehicles, to supply the active materials with high-performances and then to recycle their wastes are two core issues for the development of LIBs. In this paper, the spent graphite (SG) in LIBs is used as raw materials to fabricate two comparative high-capacity graphite anode materials. Based on a microsurgery-like physical reconstruction, the reconstructed graphite (RG) with a sp2+sp3 carbon surface is prepared through a microwave exfoliation and subsequent spray drying process. In contrast, the neural-network-like amorphous sp2+sp3 carbon-coated graphite (AC@G) is synthesized using a self-reconfigurable chemical reaction strategy. Compared with SG and commercial graphite (CG), both RG and AC@G have enhanced specific capacities, from 311.2 mAh g-1 and 360.7 mAh g-1 to 409.7 mAh g-1 and 420.0 mAh g-1, at 0.1C after 100 cycles. In addition, they exhibit comparable cycling stability, rate capability, and voltage plateau with CG. Because the synthesis of RG and AC@G represents two typical physical and chemical methods for the recycling of SG, these results on the sp2+sp3 carbon layer coating bulk graphite also reveal an approach for the preparation of high-performance graphite anode materials derived from SG.

    Chlorella sp. MCC 7 and Botryococcus sp. MCC 31 were investigated to enable large-scale biodiesel production from minimal constituents in the growth medium. Response surface methodology (RSM) was used to maximise the biomass productivity and lipid yield using only nitrogen (N), phosphorus (P) and potassium (K) as urea, single super phosphate and muriate of potash. The optimum values were 0.42 g/L nitrogen; 0.14 g/L phosphorus and 0.22 g/L potassium for Chlorella sp.; and 0.46 g/L; 0.14 g/L and 0.25 g/L for Botryococcus sp. Lipid yield of 42% for Chlorella sp. and 52% in Botryococcus sp. was observed. An enhancement in lipid yield by approximately 55% for Chlorella sp. and 73% for Botryococcus sp. was registered as compared to original nutrient medium. Fourier transform infrared (FTIR) analysis of extracted lipids revealed characteristic bands for triglycerides. This study provided utilisation of a practicable nutrient recipe in the form of N, P, K input for enhanced lipid yield from the selected microalgal strains.

    In this report, we describe the expression and function of human Sp5, a member of the Sp family of zinc finger transcription factors. Like other family members, the Sp5 protein contains a Cys2His2 zinc finger DNA binding domain at the C-terminus. Our experiments employing Gal4-Sp5 fusion proteins reveal multiple transcriptional domains, including a N-terminal activity domain, an intrinsic repressive element, and a C-terminal synergistic domain. Elevated expression of Sp5 was noted in several human tumors including hepatocellular carcinoma, gastric cancer, and colon cancer. To study the effects of the Sp5 protein on growth properties of human cancer cells and facilitate the identification of its downstream genes, we combined an inducible gene expression system with microarray analysis to screen for its transcriptional targets. Transfer of Sp5 into MCF-7 cells that expressed no detectable endogenous Sp5 protein elicited significant growth promotion activity. Several of the constitutively deregulated genes have been associated with tumorigenesis (CDC25C, CEACAM6, TMPRSS2, XBP1, MYBL1, ABHD2, and CXCL12) and Wnt/β-Catenin signaling pathways (BAMBI, SIX1, IGFBP5, AES, and p21 WAF1 ). This information could be utilized for further mechanistic research and for devising optimized therapeutic strategies against human cancers

    To understand the transcriptional mechanism(s) of human LH receptor (LHR) gene expression, we have identified the dominant functional cis-elements that regulate the activity of the promoter domain (-1 to -176 bp from ATG). Mutagenesis demonstrated that the promoter activity was dependent on two Sp1 domains (-79 bp, -120 bp) in a transformed normal placental cell (PLC) and the choriocarcinoma JAR cell. Both elements interacted with endogenous Sp1 and Sp3 factors but not with Sp2 or Sp4. In Drosophila SL2 cells, the promoter was activated by either Sp1 or Sp3. An ERE half-site (EREhs) at -174 bp was inhibitory (by 100%), but was unresponsive to estradiol and did not bind the estrogen receptor or orphan receptors ERR1 and SF-1. The 5' upstream sequence (-177 to -2056 bp) inhibited promoter activity in PLC by 60%, but only minimally in JAR cells. Activation of the human LHR promoter through Sp1/3 factors is negatively regulated through EREhs and upstream sequences to exert control of gene expression. Copyright 1999 Academic Press.

    Full Text Available The Use of Aglaophenia sp. Marine Biota Extract to Control Fusarium oxysporum f. sp. vanillae, a Pathogen of Vanilla Stem Rot The use of marine biota for organic fungicide material has enormous potential to be developed. The organic fungicide was directed to substitute synthetic fungicide for vanilla cultivation. Application of synthetic fungicide degraded environmental quality, therefore its applications does not support sustainable agriculture. The objective of this research was to know the potence of Aglaopheniain suppressing the growth of F. oxysporum f. sp.vanillae, the pathogen of vanilla stem rot. The research was done in green house in order to find the best substance for formulation of the extract. The substances screened were water, tween-80, and detergents with two different concentrations. Subsequently, two best formulas were chosen to apply in endemic area in Tabanan. The green house and field trial research used Randomized Completely Design with three and five replications respectively. Results showed that tween was the best substance used for formulation and concentration of 0.2% was better than other concentrations. The extract diluted in tween-80 on the concentration of 0.2% showed the lowest rot on stem, longest shoot, and the most leaves on vanilla shoot. Because of its significant performance, the 0.1% extract ofAglaopheniain 0.1% tween-80 was proposed to be the best formula to suppress the vanilla stem rot disease.

    Full Text Available New carbon allotropes can be designed by combining sp, sp2 and sp3 three hybridization states. And the hybridization states or coordination numbers of carbon atoms can be changed by applying high pressure on carbon materials. In this study, a common high pressure phase (named as TBBC transformed from AB-stacking graphyne or THD-graphene is predicted. Its kinetic stability is examined using finite displacement method. We find that the sp2 and sp3 hybridized carbon atoms behave different vibration features at high frequency region. Both graphene-like and diamond-like vibration peaks occurs. Phase transition energy barriers from both graphyne and THD-graphene to TBBC are estimated. Electronic structure calculations show that the TBBC is an indirect semiconductor with a bandgap of 0.66 eV. The ideal tensile strength of TBBC is high in [0001] and [11¯00] directions, but is weak along [12¯10] direction.

    Full Text Available Petroleum oil is a complex mixture of substances, the majority of which are hydrocarbons; the latter represent an extremely important and heterogeneous group of compounds that find their way into water resources by anthropogenic or natural ways. The majority of toxic hydrocarbon components of petroleum are biodegradable, where bioremediation using microbial species has become an integral process for the restoration of oil-polluted areas. In this study, three bioremediation processes, namely natural attenuation, nutrient supplementation by adding glucose and biostimulation by adding Tween® 80, were carried out in various petroleum hydrocarbon concentrations in polluted water media using a consortium of three protozoan isolates (Aspidisca sp., Trachelophyllum sp. and Peranema sp.. A first-order kinetics model was fitted to the biodegradation data to evaluate the biodegradation rate and to determine the corresponding half-life time. First-order kinetics satisfactorily described the biodegradation of the petroleum-based contaminants under abiotic conditions. The results showed an increase in the percentage removal of petroleum oil at the lower petroleum concentrations and a gradual percentage decrease in removing petroleum oil residues occurred when there was an increase in the initial concentrations of the petroleum oil: 39%, 27%, 22%, 12%, 10% for various petroleum oil concentrations of 50, 100, 150, 200, 250 mg/L, respectively. A similar trend was also observed in the glucose-supplemented culture media where the reduction was 45% and 78% for petroleum concentrations of 250 mg/L and 50 mg/L, respectively. Biodegradation of between 33 and 90% was achieved at a Tween® 80 concentration of between 50 mg/L and 250 mg/L. The degradation rate constants for the natural attenuation process ranged between ≥0 to ≤0.50, ≥0 to ≤0.35, ≥0 to ≤0.25, ≥0 to ≤ 0.14 and ≥ 0 to ≤0.11 for petroleum oil concentrations varying from 50, 100, 150

    Full Text Available O objetivo deste artigo, resultado de pesquisa que deu origem à Monografia de Conclusão de Curso em Hotelaria, da UAM, 2011, é apresentar os resultados de uma investigação sobre o grau de satisfação dos visitantes do Santuário mariano de Aparecida do Norte, S.P, relativo ao sistema de hospedagem e serviços gastronômicos, supostamente insuficientes e deficitários na cidade. O trabalho fundamenta-se teoricamente nas idéias do geógrafo Christian Dennys Monteiro Oliveira que compreende o turismo religioso como peregrinação contemporânea e o visitante de Aparecida como romeiro urbano acostumado a acessar bens e serviços das metrópoles. Metodologicamente primeiramente foi realizada uma pesquisa exploratória com consultas a sites oficiais e comerciais que levaram à confirmação da precariedade dos serviços de hotelaria e alimentação na cidade. Em um segundo momento foi aplicado um questionário em uma amostra composta de 100 visitantes, entre hóspedes e não-hóspedes da cidade, que recebeu posteriormente análise probabilística. Os resultados apontam uma avaliação majoritariamente positiva em relação aos recursos de hospedagem e alimentação de Aparecida. Concluiu-se que a cidade e a municipalidade sofreram um atrofiamento em função da presença do Santuário, que exerce um monopólio das ações receptivas impostas pelo poder clerical desde suas origens, não havendo políticas públicas para o planejamento e gestão do turismo religioso em Aparecida. Por outro lado, concluiu-se que o novo romeiro urbano que para lá se dirige habituado ao uso de bens turísticos, apresenta uma crítica diminuída em relação à qualidade dos serviços ofertados na região, conformando-se com a precariedade. É possível que a submissão às deficientes condições de hospedagem e serviços alimentícios seja o remanescente contemporâneo do sofrimento que no passado se fazia necessário na peregrinação, penitência ou romaria.

    Aspergillus sp. N2 and Penicillium sp. N3 are chromate-resistant filamentous fungi that were isolated from Cr(VI) contaminated soil based on their ability to decrease hexavalent chromium levels in the growth medium. After 120 h of growth in a medium containing 50 ppm Cr(VI) at near neutral pH, Aspergillus sp. N2 reduced the Cr(VI) concentration by about 75%. Penicillium sp. N3 was able to reduce the Cr(VI) concentration by only 35%. However, Penicillium sp. N3 reduced the Cr(VI) concentration in the medium by 93% under acidic conditions. Interestingly, the presence of Cu(II) enhanced the Cr(VI) reducing ability of Aspergillus sp. N2 and Penicillium sp. N3 at near neutral pH. Aspergillus sp. N2 and Penicillium sp. N3 reduced the Cr(VI) concentration in the growth medium to a virtually undetectable level within 120 h. For both Aspergillus sp. N2 and Penicillium sp. N3, mycelial seed cultures were more efficient at Cr(VI) reduction than conidium seed cultures. The mechanisms of Cr(VI) reduction in Aspergillus sp. N2 and Penicillium sp. N3 were enzymatic reduction and sorption to mycelia. Enzymatic activity contributed significantly to Cr(VI) reduction. Aspergillus sp. N2 and Penicillium sp. N3 reduced the levels of Cr(VI) in polluted soil samples, suggesting that these strains might be useful for cleaning up chromium-contaminated sites.

A maioria (98% era sexualmente ativa; 35% haviam tido mais de 15 parceiras(os sexuais ao longo da vida; 8% haviam tido experiências homossexuais (dentro ou fora da Febem; 12% já haviam trocado sexo por benefícios materiais; e 22% já eram pais. Muitos dos adolescentes afirmaram que adquirir o HIV "é parte da vida" e que suas vidas apresentam riscos piores, como sobreviver na criminalidade. Acreditam que o preservativo é frágil (83% e atrapalha a relação sexual (58%; 72% já haviam utilizado preservativo, mas apenas 9% o utilizavam sempre. CONCLUSÕES: Os adolescentes apresentaram um elevado risco de aquisição do HIV. Assim, torna-se necessário integrar a prevenção da Aids em sua problemática de vida e em temas como racismo, esperança pelo futuro, criminalidade, uso de drogas, direitos fundamentais, incluídos nestes os referentes ao sexo e à reprodução, mostrando existir alternativas a adquirir o HIV ou morrer na criminalidade.

    Full Text Available Fundamento: As patologias cardiovasculares são a maior causa de morbimortalidade nos países desenvolvidos e emergentes. Sua principal etiologia, a aterosclerose, é doença disseminada acometendo os territórios coronariano, cerebral e periférico. A doença arterial obstrutiva periférica (DAOP, além de suas consequências per se, sinaliza o acometimento do território coronariano. Portanto, seu melhor conhecimento permite tratamento adequado, retardando complicações locais e à distância, diminuindo o custo para o sistema de saúde. Objetivo: Este estudo estima a porcentagem de DAOP em nipo-brasileiros de Bauru (SP, reconhecidos pela alta prevalência de distúrbios metabólicos, como hipertensão arterial (43%, diabetes melito (33% e hipercolesterolemia (60 %, e analisa a associação com biomarcadores de risco. Métodos: Este estudo transversal populacional avaliou 1.330 nipo-brasileiros de ambos os sexos com idade ≥ 30 anos que foram submetidos a exame físico completo, medidas antropométricas, exames laboratoriais e índice tornozelo-braço (ITB. Participantes com ITB ≤ 0,90 foram diagnosticados como portadores de DAOP. Após aplicação dos critérios de exclusão, 1.038 indivíduos integraram a análise. Empregou-se regressão de Poisson para análise das associações com DAOP. Resultados: A idade média foi 56,8 anos e a porcentagem de DAOP foi 21,1%, igual entre os sexos. DAOP associou-se com tabagismo (RP 2,16 [1,33-3,48] e hipertensão arterial (RP 1,56 [1,12-2,22]. Conclusão: A porcentagem de DAOP nos nipo-brasileiros foi semelhante à de outras populações de perfil cardiometabólico desfavorável (US PARTNERS e POPADAD. A associação independente de DAOP com tabagismo e hipertensão, mas não com outros clássicos fatores de risco, pode depender das frequências muito elevadas dos distúrbios metabólicos nessa população.

    The implementation and performance of a parallel spatial direct numerical simulation (PSDNS) approach on the Intel iPSC/860 hypercube and IBM SP1 and SP2 parallel computers is documented. Spatially evolving disturbances associated with the laminar-to-turbulent transition in boundary-layer flows are computed with the PSDNS code. The feasibility of using the PSDNS to perform transition studies on these computers is examined. The results indicate that PSDNS approach can effectively be parallelized on a distributed-memory parallel machine by remapping the distributed data structure during the course of the calculation. Scalability information is provided to estimate computational costs to match the actual costs relative to changes in the number of grid points. By increasing the number of processors, slower than linear speedups are achieved with optimized (machine-dependent library) routines. This slower than linear speedup results because the computational cost is dominated by FFT routine, which yields less than ideal speedups. By using appropriate compile options and optimized library routines on the SP1, the serial code achieves 52-56 M ops on a single node of the SP1 (45 percent of theoretical peak performance). The actual performance of the PSDNS code on the SP1 is evaluated with a "real world" simulation that consists of 1.7 million grid points. One time step of this simulation is calculated on eight nodes of the SP1 in the same time as required by a Cray Y/MP supercomputer. For the same simulation, 32-nodes of the SP1 and SP2 are required to reach the performance of a Cray C-90. A 32 node SP1 (SP2) configuration is 2.9 (4.6) times faster than a Cray Y/MP for this simulation, while the hypercube is roughly 2 times slower than the Y/MP for this application.
