    Full Text Available AIM: This study determined the temporal variation of the biomass and the concentrations of carbon, nitrogen and phosphorus in Azolla filiculoides Lam. in a small (0.5 ha shallow dystrophic lake located in the city of Rio Grande (Rio Grande do Sul State, Brazil. METHOD: Sampling was conducted monthly between November 2000 and October 2001. The macrophytes were collected randomly in three replicates with a circular collector 0.3 m in diameter and subsequently washed with tap water and oven-dried at 60 ºC for determination of the dry weight and the nutrient status (i.e., carbon, nitrogen and phosphorus. Primary productivity was estimated by the variation in biomass among successive samples. RESULTS: A. filiculoides was present in the lake throughout the year and occupied between 50 and 80% of the surface area. The biomass values ranged from 34.2 g DW.m-2, recorded in May (autumn, to 170.9 g DW.m-2 in January (summer. The highest rate of primary productivity was 3.3 g DW.m-2.d-1, observed in June. The concentrations of carbon, nitrogen and phosphorus in the plant ranged between 403 and 551 g.kg-1, 13.4 and 25.7 g.kg-1 and 0.5 and 1.9 g.kg-1, respectively. The water N:P ratio ranged between 19:1 and 368:1. CONCLUSION: The coverage of the surface of the lake by A. filiculoides throughout the study period and the nutritional status of the plant demonstrate the importance of the cycling of nutrients by macrophytes in this aquatic environment. The higher N:P ratio in the water column, compared with other neighboring environments without macrophytes, shows that the enrichment of the lake may result from the biological N-fixation activity produced by A. filiculoides.OBJETIVO: Este estudo determinou a variação temporal da biomassa e as concentrações de carbono, nitrogênio e fósforo de Azolla filiculoides Lam., em um pequeno lago raso distrófico situado no município do Rio Grande (Rio Grande do Sul, Brasil.

    Full Text Available AIMS: We evaluated the potential of aquatic macrophyte communities as bioindicators in six small shallow lakes. METHODS: The sampling was conducted monthly for one year, during which all macrophytes were surveyed, and the water temperature, dissolved oxygen, pH, conductivity, total alkalinity, chlorophyll-a, suspended matter, total nitrogen (Nt and total phosphorus (Pt were measured. RESULTS: In total, forty-three species were recorded, and there were significant differences in the species richness and limnological conditions among the lakes studied. A canonical correspondence analysis showed that the concentration of nutrients (Nt and Pt, chlorophyll-a, suspended matter, dissolved oxygen and pH were the most important predictors of the distribution of macrophytes. Some emergents were related to the high concentration of nutrients, chlorophyll-a, and suspended matter. Moreover, the most submersed species were associated with environments with low nutrient concentrations and the lowest values chlorophyll-a and suspended matter. In addition, some species submerged and floating were related to low values pH, alkalinity and dissolved oxygen. Limnological differences between lakes may be cited as the main causes of the observed heterogeneous distribution of macrophytes. CONCLUSIONS: These results indicate the importance of limnological characteristics of the different environments in the macrophyte community composition and the potential role of this community as a bioindicator in shallow lakes in southern Brazil.OBJETIVO: Foi avaliado o potencial bioindicador da comunidade de macrófitas aquáticas em seis pequenos lagos rasos. MÉTODOS: O acompanhamento foi mensal durante um ano, sendo que em cada coleta, além do registro de todas as espécies de macrófitas foram determinadas a temperatura da água, oxigênio dissolvido, pH, condutividade elétrica, alcalinidade total, clorofila-a, material em suspensão, nitrogênio total (Nt e fósforo total

Descrever os principais inputs e outputs do festival; verificar as expectativas do atores envolvidos e; identificar o real envolvimento entre o trade turístico, a municipalidade e a organização do evento foram os principais objetivos estabelecidos. Esses objetivos foram alcançados a partir de revisão bibliográfica e documental; das visitas a campo e; das aplicações de questionários e entrevistas. Após a coleta, as evidências foram sistematizadas e analisadas, proporcionando uma reflexão sobre o caso, exposto em forma de relatório. O estudo balizado por conceitos de autores como Andrade (2002; Bienenstein (2011; Sarmento (2007/13; Vilaça (2010; entre outros, apresentou como principais resultados a ínfima articulação do poder público tanto com a organização do evento, como com os empreendimentos ligados a oferta turística do município e; o evento como principal receptor dos turistas, que concentra e oferece produtos e serviços que suprem as necessidades dos participantes do festival, dificultando o contato dos mesmos com a população autóctone. A problemática foi escolhida devido ao seu caráter atual e sua crescente expansão nas discussões acadêmicas. O trabalho buscou, principalmente, cooperar com as bibliografias sobre o tema e alertar sobre os impactos causados por acontecimentos como o Tomorrowland Brasil. Por isso, pretendeu ser de importância tanto para a academia como para a sociedade.

    Full Text Available A agricultura familiar é fundamental na geração de emprego, renda e alimentos à própria família e aos mercados consumidores. Para a promoção, o governo federal estabeleceu leis, decretos, programas e planos voltados ao desenvolvimento rural, desprendendo-se da Revolução Verde e incorporando ações estratégicas da Agroecologia. Neste estudo, objetivou-se analisar a estrutura produtiva e avaliar o índice de agroecologia do sistema de produção agrícola adotado pelos agricultores familiares vinculados a Associação dos Pequenos Produtores da Região do Alto Sant’Ana, beneficiários do Programa de Aquisição de Alimentos no município de São José dos Quatro Marcos, Mato Grosso. Desta forma, utilizou-se a ferramenta de entrevista semiestruturada com o propósito de proceder o levantamento documental acerca da estratificação do imóvel rural e a coleta de dados sobre a distribuição do sistema de trabalho, a infraestrutura presente, as práticas agrícolas desenvolvidas, a produção pecuária e agrícola consolidada e o sistema de produção. Para o cálculo do Índice Agroecológico formatou-se um modelo matemático embasado nas teorias agroecológicas. As análises indicaram que os produtores rurais estão organizados em pequenas unidades produtivas, dotados de mão de obra familiar; infraestrutura rural relativamente ampla; produção pecuária e agrícola que atendem as necessidades da família e o excedente comercializado; sistema de produção diversificado, com técnicas agrícolas em estado de transição agroecológica, entretanto carentes de políticas públicas eficientes que contemplem a agroecologia no sistema de produção rural; crédito agrícola específico; assistência técnica capacitada para esta demanda e a formação de canais para comercialização da produção.

    Full Text Available OBJETIVO: Examinar o efeito da nutrição precoce sobre o tempo para atingir a nutrição completa em neonatos prematuros (PIG estáveis pequenos para a idade gestacional. MÉTODO: Os neonatos prematuros com idade gestacional inferior a 37 semanas e peso ao nascer inferior a 10% foram alocados aleatoriamente para um regime de nutrição precoce (nas primeiras 24 horas de vida ou tardia (após as primeiras 24 horas de vida. Todos os neonatos apresentaram uma evidência intrauterina de fluxo diastólico reverso ou ausente. Os neonatos incapazes de iniciar uma nutrição precoce foram excluídos. O tempo para a alimentação completa, a progressão da nutrição e morbidez correspondente foram comparados. A eletrogastrografia (EGG foi utilizada para mensurar a motilidade gástrica pré e pós-prandial no segundo e no sétimo dias após o início da nutrição. RESULTADOS: Foram incluídos 60 neonatos no estudo, sendo 30 em cada grupo. Os neonatos incluídos no regime de nutrição precoce atingiram a nutrição enteral completa antes dos neonatos do grupo de controle (98±80-157 em comparação a 172±1 23-261 horas de idade, respectivamente; p = 0,004 e recebiam alta hospitalar antes (p = 0,04. Nenhuma enterocolite necrosante (ECN foi comprovada em ambos os grupos de estudo. A motilidade gástrica melhorou no sétimo dia após o início da nutrição em ambos os grupos de estudo, sem diferença entre eles. CONCLUSÕES: Os neonatos prematuros PIG estáveis em regime de nutrição precoce atingiram alimentação enteral completa e receberam alta hospitalar significativamente antes que aqueles em regime de nutrição tardio, sem morbidez excedente.

    Full Text Available Este estudo tem como objetivo a compreensão da experiência vivida pelos gestores envolvidos no Consórcio de Desenvolvimento Sustentável da Quarta Colônia (Condesus/Quarta Colônia, a partir da reflexão de seus atores principais. O Condesus/Quarta Colônia é um consórcio de nove municípios que formam uma aliança estratégica em busca do desenvolvimento sustentável da região. Com base nas reflexões dos principais atores organizacionais, desvela-se a experiência de ser-gestor do Condesus/Quarta Colônia. O desvelamento do fenômeno foi possível por meio de suas quatro essências significativas da experiência de ser-gestor do consórcio em questão. A primeira essência é a da superação, uma essência provocativa que declara a superação das divergências, conflitos e rivalidades históricas, pessoais e políticas em nome de um futuro próspero em comum. A segunda essência desvelada foi a da força provocada pela união dos municípios por meio do consórcio. Vê-se que isso gerou um sentimento de orgulho (a terceira essência entre seus membros e que esse sentimento ultrapassou as fronteiras físicas do consórcio, perpassando, hoje, por toda a comunidade, conforme as falas de seus gestores. A quarta essência do ser-gestor do consórcio compreende estar imerso em um processo, aceitando e lidando com as conjunturas, mudanças externas e internas e, diante disso, apreendendo a lidar com as frustrações e se auto-organizando continuamente.

    Full Text Available A qualidade de produtos alimentícios é considerada como um indicador das condições de produção e uma questão de saúde pública. A definição de que o alimento seja seguro e inócuo para o consumo depende de resultados analíticos confiáveis os quais possibilitam monitorar e orientar os processos produtivos. Assim, é fundamental que as metodologias de análise e a sua realização, estejam em conformidade com normas e parâmetros validados. As Boas Práticas de Laboratório (BPL são definidas como um sistema da qualidade aplicado a laboratórios com o objetivo de promover a qualidade e a validação dos resultados laboratoriais. Os órgãos fiscalizadores exigem a implementação das BPL nos laboratórios das indústrias de laticínios. Os objetivos desta pesquisa foram avaliar as dificuldades das empresas na compreensão, elaboração e implantação do manual de BPL por meio da metodologia de pesquisa qualitativa do discurso do sujeito coletivo e desenvolver diretrizes para a elaboração de manual de BPL para indústrias de laticínios de pequeno e médio porte. Foram realizadas entrevistas com funcionários de laboratórios de três laticínios da região de Leopoldina-MG e a análise do discurso do sujeito coletivo (DSC dessas entrevistas. Assim, detectou-se uma grande dificuldade por parte dos colaboradores das empresas no entendimento, elaboração e implantação do manual de BPL o que indicou a necessidade de elaboração de diretrizes para orientar a elaboração do Manual de BPL.

    Full Text Available Neste início do século XXI muitos estudos apresentam como foco as alianças estratégicas, que nos segmentos industriais se dão através da integração vertical da cadeia de produção. Essa estratégia de cooperação busca a aquisição de novas vantagens competitivas em segmentos altamente competitivos. Assim como nos segmentos industriais, o setor varejista tem visto sua lucratividade decair com o aumento da concorrência. A entrada no país de grandes redes internacionais a partir da década de 1990 exigiu que os pequenos e médios comerciantes locais também buscassem alternativas para a ampliação de suas vantagens competitivas. Os pequenos varejistas, não dispondo de poder de barganha dentro da estrutura de sua indústria, passaram a buscar nas redes de cooperação elementos que pudessem contribuir para a sua permanência no mercado. Este artigo visa identificar como está ocorrendo esse processo e quais os benefícios e os entraves à formação de redes associativistas entre concorrentes. Mediante a análise de dois casos (uma rede de supermercados e uma rede de materiais de construção puderam-se averiguar as vantagens e desvantagens desse processo para os pequenos varejistas.Early in the 21st Century studies have focused on strategic alliances in industrial segments through integration of the productive chain. This cooperative strategy targets the acquisition of competitive advantages in highly competitive activities. Profits of small and medium retailers have also suffered from sharpened competition by large international networks since 1990, which has caused them to search for and adopt more competitive alternatives. Purchasing advantages have been strengthened by their collaboration in networks in order to increase bargaining power. This activity is described as well as the benefits and obstacles of establishing associative networks with competitors. Analyses of the formation of a network of supermarkets and another of

    Full Text Available Neste artigo propomos um modelo de otimização inteira mista para o problema de dimensionamento e seqüenciamento dos lotes de produção em fábricas de refrigerantes de pequeno porte, com tempos e custos de set up de produção dependentes do seqüenciamento dos lotes. O modelo considera o estágio de envase como sendo o gargalo da produção da planta, o que é comum em fábricas de pequeno porte com uma única linha de envase, e restrições de lote mínimo do estágio de xaroparia. Variações da heurística relax and fix são propostas e comparadas na solução de exemplares do modelo, gerados com dados reais de uma fábrica localizada no interior do Estado de São Paulo. Os resultados mostram que as abordagens são capazes de gerar soluções melhores do que as utilizadas pela empresa.In this paper we propose a mixed integer programming model to the lot sizing and sequencing problem of a soft drink plant with sequence-dependent set up costs and times. The model considers that the bottling stage is the production bottleneck, which is common in small plants with only one production line, and minimum lot size constrains of the syrup stage. Variations of the relax and fix heuristic are proposed and compared. A computational study with instances generated based on real data from a plant situated in the State of São Paulo-Brazil is also presented. The results show that the approaches are capable to produce better solutions than the ones from the company.

    Full Text Available Este estudo teve como objetivo compreender como o consumo de psicofármacos se legitimou como uma tecnologia de si no interior do dispositivo de medicalização. Concluímos que esta é uma tecnologia que incide sobre os corpos por estar acoplada aos modos de subjetivação contemporâneos. A análise aqui apresentada trata do contexto social de Boa Vista das Missões, um pequeno município do Rio Grande do Sul. Realizamos uma pesquisa de campo com seis meses de duração e entrevistamos uma amostra de 400 pessoas. A análise dos relatos e das informações construídas buscou dar visibilidade aos enunciados presentes nas formações discursivas e que definem e explicam o consumo de psicofármacos por 53% da população da cidade. Utilizamos a perspectiva genealógica de Michel Foucault para refletir sobre este campo de pesquisa e problematizar a produção de modos de vida marcados por formas de controle individualizantes e totalizantes ao mesmo tempo. Neste sentido, partimos do histórico da inserção dos psicofármacos em nossa cultura para entender as dimensões que ocupam neste contexto. A análise identificou as redes enunciativas no interior do dispositivo de medicalização que fundamentam uma apresentação do biopoder que se sustenta no tripé "dependência, assistencialismo, individualismo".The goal of this research was to comprehend how the consumption of psychoactive prescribed drugs was legitimated as a technology of the self inside the medicalization device (dispositf.

    Full Text Available As áreas inundáveis localizadas na bacia dos rios Amazonas e Solimões são denominadas várzeas. A inundação é um evento natural que promove mudanças na estrutura e composição florística dessas comunidades. O conhecimento da diversidade de espécies é de fundamental importância para o entendimento da dinâmica da regeneração natural de espécies nos ecossistemas amazônicos. Este trabalho teve como objetivo levantar a composição florística do solo do fundo do lago do Manaquiri-AM, em um período de seca excepcional, ocorrida em 2005, na Amazônia. Foram realizadas coletas de material botânico em duas áreas do lago, em novembro de 2005; para a amostragem, utilizou-se um quadrado de madeira de 0,36 m², atirado aleatoriamente por 20 vezes em cada local de estudo. A vegetação emergente foi de 5.958 indivíduos, distribuídos em sete famílias e nove espécies. As famílias mais representativas em número de espécies foram Poaceae e Cyperaceae. Cyperus esculentus e Luziola spruceana foram as mais frequentes, e Mimosa pudica e Alternanthera sessilis, as de maior abundância. C. esculentus e M. pudica apresentaram maior número de indivíduos, de densidade e de valor de importância. As espécies de plantas encontradas neste estudo mantiveram sua capacidade de crescer e se desenvolver mesmo após longo período submersas.The swamps located at the basins of the Amazonas and Solimões rivers are denominated "várzeas". In these areas, flooding is a natural event that changes the structure and composition of the local plants. Thus, knowing the species diversity in these Amazon region areas is extremely important to understand the dynamics of the natural regeneration of the Amazon ecosystem species. Accordingly, the goal of this study was to survey the soil floristic composition at the bottom of the Manaquiri Lake, Amazon, during an exceptional dry period in 2005. Plants were collected in two areas of the lake in November 2005. Flora

A incidência constante de gestos previamente levantados por Luciane CARDASSI (1998 em outras obras de Kiefer bem como a presença do elemento octatônico são estudados e inter-relacionados com obras precedentes do compositor. A teoria dos conjuntos de Allan Forte é utilizada aqui como base teórica. A densidade gestual encontrada nesta composição de data tardia em meio ao conjunto de obras para piano do autor e sua curta duração apontam para uma síntese estilística.The present article offers an analysis of the musical gestures and intervallic configurations of the composition Vastidão [Vastness], which belongs to the set entitled Seis Pequenos Quadros [Six Small Pictures] (1981 for piano by Brazilian composer Bruno Kiefer. The recurring musical gestures from other of Kiefer's compositions, previously surveyed by Luciane CARDASSI (1998, as well as the presence of octatonic elements, are studied and related to preceding Kiefer's works.

    Full Text Available OBJETIVO: Avaliar a participação de pequeno número de estudantes da Universidade de Caxias do Sul em um programa de tratamento do tabagismo. MÉTODOS: Delineamento transversal e comparativo entre alunos que se inscreveram em um programa de tratamento do tabagismo e alunos que não se inscreveram. RESULTADOS: De 108 alunos não inscritos, 102 não mostraram intenção de parar de fumar (94,4%, intervalo de confiança de 95% de 88,29% a 97,93%. As comparações entre inscritos e não inscritos mostraram diferenças estatísticas, respectivamente: nas idades 35 e 23 anos, p OBJECTIVE: To evaluate the limited participation by university students in a smoking cessation program. METHODS: A cross-sectional, comparative study was conducted at the University of Caxias do Sul, located in Caxias do Sul, Brazil, involving students who enrolled in a smoking cessation program, together with those who did not. RESULTS: Of the 108 student who did not enroll in the program, 102 (94.4% stated that they had no intention to quit smoking (95% confidence interval: 88.29-97.93%. Comparisons between the enrolled and nonenrolled students revealed the following statistical differences: in mean age (35 vs. 23 years, p < 0.01; mean duration of the smoking habit (19.42 vs. 7.36 years, p < 0.01; considering oneself addicted (100% vs. 58.5%, p = 0.047; believing oneself able to stop smoking at any time (7.1% vs. 22.6%, p = 0.02; having no knowledge of any reasons to quit smoking (37.5% vs. 12%, p = 0.03; having suffered discrimination (42.9% vs. 9.3%, p < 0.01. CONCLUSION: Among the university students evaluated, there was a phase, classified as precontemplative or contemplative, during which they were refractory to smoking cessation. Although all of the students were aware of the diseases caused by smoking, 41.5% did not consider themselves addicted. The concept of substance dependence does not apply to these students. It would seem more appropriate to define nicotine

    Full Text Available AIM: To evaluate leaf degradation and invertebrate colonization of Salix humboldtiana Willd. in a subtropical shallow lake on the coastal plain of Rio Grande do Sul, Brazil; METHODS: Litter bags containing 6.85 g of leaves were incubated in the superficial layer of sediment in the littoral region for 1, 4, 7, 14, 32, 47 and 71 days; RESULTS: After 71 days, a loss of 51% of the initial leaf weight was observed (k = 0.0100 d-1. We estimated that it would take 300 days to lose 95% of the initial weight. A total of 16040 organisms and 35 taxa were identified. Caenidae (25.9%, Oligochaeta (19%, Ostracoda (13.8%, Hydracarina (9.8%, Tanypodinae (9.7% and Coenagrionidae (7.7% were the most highly represented taxa. We observed increases in density, richness and diversity of taxa over time, with a stabilizing trend noted in the taxa diversity. Regarding the functional trophic groups (FTGs, gathering-collectors accounted for 57.6% of the community, while predators (25%, scrapers (15.8%, filtering-collectors (0.88% and shredders (0.73% were also represented. The diversity and evenness of the FTGs had stabilized by day 14; CONCLUSIONS: S. humboldtiana detritus provides a favorable habitat for a sufficient duration to support a high density and diversity of aquatic invertebrates. The small percentage of shredders indicates the minor influence of the invertebrate community on the rate of detrital degradation. The main contribution of invertebrates to detrital processing comes from the consumption of fine particulate organic matter by gathering-collectors.OBJETIVOS: Avaliar a degradação foliar de Salix humboldtiana Willd. e a colonização pela comunidade de invertebrados aquáticos em um lago raso subtropical, planície costeira do Rio Grande do Sul, Brasil; MÉTODOS: Bolsas de decomposição contendo 6,85 g de folhas foram incubadas na região litorânea, na superfície do sedimento, e retiradas após 1, 4, 7, 14, 32, 47 e 71 dias de decomposi

    Full Text Available O artigo tem por objetivo oferecer aos definidores de política pública, aos governantes e aos mais diversos grupos de interesse da população brasileira conhecimentos comparativos úteis para que opinem, decidam e ajam a respeito de mega e pequenos eventos, facilitando ainda a pesquisa bibliográfica de estudantes e pesquisadores. A literatura mostra que os efeitos de um megaevento são um tema controverso. No Brasil, sede da Copa das Confederações em 2013, da Copa do Mundo em 2014 e dos Jogos Olímpicos em 2016, ainda há um importante questionamento sobre se o país, tão carente de melhorias em áreas como saúde e educação, deveria sediar megaeventos como esses. Soma-se a isso o questionamento se não seria melhor priorizar pequenos eventos nos países em geral. Os governantes e empresas interessadas na realização de megaeventos frequentemente superestimam seus efeitos positivos para a sociedade anfitriã, enquanto a literatura especializada considera que o saldo dos efeitos reais não é necessariamente positivo e, mais, tende a ser negativo. Com base nisso, desenvolveu-se e tornou-se forte a linha de entendimento de que os pequenos eventos são mais benéficos, têm maiores possibilidades de sucesso e maior potencial de efeito socioeconômico positivo – sendo assim recomendáveis no lugar de megaeventos para os países em geral, o que inclui o Brasil.

    Full Text Available Os amborês e peixes-macaco, como são popularmente conhecidos gobiídeos e bleniídeos, são elementos dominantes da fauna de pequenos peixes bentônicos e litorâneos que habitam recifes tropicais, compondo grande parte da alta diversidade das espécies de pequeno porte encontrada no Atlântico ocidental. O estudo da distribuição e história natural dos gobióides e blenióides de Fernando de Noronha foi desenvolvido através de observações de campo. Além da descrição dos hábitats preferenciais foram abordados aspectos sociais tais como, habitat preferencial, interações intra- e interespecíficas, comportamento domiciliar e territorial, e comportamento reprodutivo. A maioria das espécies em foco apresenta distribuição principalmente litorânea, são gregárias, com áreas domiciliares relativamente pequenas em torno de 2 x 2 m², pouco agressivas, tendo sido ocasionalmente registradas curtas perseguições intra- e interespecíficas. A baixa agressividade registrada, em comparação com outros peixes é provavelmente associada à adaptação à ocupação de pequenas áreas, como é o caso das poças de marés, pois um grande número de interações agressivas representaria um gasto de energia desnecessário. No geral, as espécies possuem coloração críptica, associada à evitação de predadores. Apenas nestas épocas de reprodução foi observada a intensificação da agressividade, com comportamento territorial - defesa de território incluindo mordidas e perseguições.The gobis and blenis (Gobiidae and Bleniidae are the most important group of small benthic littoral fishes in tropical reefs, representing most of the high number of small fish species found in Western Atlantic.

Los resultados indicaron que el IRFS ha presentado valores superiores a lo largo de los años estudiados y que la estructura financiera del municipio y los cocientes de balance patrimonial han sufrido alteraciones positivas. Este escenario sugiere que el fortalecimiento de la capacidad de inversión y de la capacidad de saldar las deudas, aliado a una atención a la capacidad de gestión y a la capacidad de responder a las demandas sociales, puede revertir en mejores resultados para el municipio y, en consecuencia, para la propia municipalidad.

  9. LAGO: The Latin American giant observatory

    Science.gov (United States)

    Sidelnik, Iván; Asorey, Hernán; LAGO Collaboration

    2017-12-01

    The Latin American Giant Observatory (LAGO) is an extended cosmic ray observatory composed of a network of water-Cherenkov detectors (WCD) spanning over different sites located at significantly different altitudes (from sea level up to more than 5000 m a.s.l.) and latitudes across Latin America, covering a wide range of geomagnetic rigidity cut-offs and atmospheric absorption/reaction levels. The LAGO WCD is simple and robust, and incorporates several integrated devices to allow time synchronization, autonomous operation, on board data analysis, as well as remote control and automated data transfer. This detection network is designed to make detailed measurements of the temporal evolution of the radiation flux coming from outer space at ground level. LAGO is mainly oriented to perform basic research in three areas: high energy phenomena, space weather and atmospheric radiation at ground level. It is an observatory designed, built and operated by the LAGO Collaboration, a non-centralized collaborative union of more than 30 institutions from ten countries. In this paper we describe the scientific and academic goals of the LAGO project - illustrating its present status with some recent results - and outline its future perspectives.

    Full Text Available In this study, the hourly air temperature differences between City hall (urban and Okoafo (rural in Lagos, Nigeria, were calculated using one year of meteorological observations, from June 2014 to May 2015. The two sites considered for this work were carefully selected to represent their climate zones. The city core, City hall, is within the Local Climate Zone (LCZ 2 (Compact midrise while the rural location, Okoafo, falls within LCZ B (Scattered Trees in the south-western part on the outskirt of the city. This study is one of very few to investigate urban temperature conditions in Lagos, the largest city in Africa and one of the most rapidly urbanizing megacities in the world; findings show that maximum nocturnal UHI magnitudes in Lagos can exceed 7 °C during the dry season, and during the rainy season, wet soils in the rural environment supersede regional wind speed as the dominant control over UHI magnitude.

    Full Text Available This article attempts to discuss on concept of moral economy, presenting the case of "pequenos lavradores" (quatters in Rio de Janeiro' landscape between 1945-1964. In the first place, the focus falls on the discussion of anthropologists as Klaas and Ellen Woortman about that concept. In the second, I make a verification one of how moral economy one has been expressed by "pequenos lavradores" in you fight for the land. My hypothesis is that moral economy one not is only a set of values, but it play too an important rule in the establishment of a political speech one and of your social identity. The sources explored are newspapers, peasant meeting documents and letters envoy to the President Getúlio Vargas.Este artigo tenta discutir sobre o conceito de economia moral, apresentando o caso dos pequenos lavradores na zona rural do Rio de Janeiro entre os anos de 1945-1964. Em primeiro lugar, o foco recai sobre a discussão de antropólogos como Klaas e Ellen Woortman sobre aquele conceito. Em segundo, eu realizo uma verificação de como uma economia moral foi expressa por "pequenos lavradores" em suas lutas pela terra. Minha hipótese é que a economia moral não é apenas um conjunto de valores, mas possui também um importante papel no estabelecimento de um discurso político e de uma identidade social. As fontes por mim exploradas foram jornais, documentos de encontros camponeses e cartas enviadas ao presidente Getúlio Vargas.

    2017-04-01

    Full Text Available O artigo em questão é fruto das pesquisas desenvolvidas pelo Programa de Educação Tutorial – PET Educação do Campo e Movimentos Sociais na UFRRJ – Universidade Federal Rural do Rio de Janeiro. Ele aborda o protagonismo do MPA – Movimento dos Pequenos Agricultores, na interface entre agricultura familiar e educação do campo. Trabalhamos com o plano camponês, uma das principais armas do MPA. Ele representa um contraponto à incapacidade estatal na criação de leis que apoiem os pequenos agricultores. Desenvolvemos uma pesquisa bibliográfica e documental, utilizando as seguintes fontes de investigação: legislações, portarias, decretos e referenciais sobre educação do campo no Brasil. Utilizamos ainda os dados do censo agropecuário de 2006, ressaltando o valor da agricultura familiar na mesa do brasileiro. Nesse contexto, verificamos que o processo de ensino e aprendizagem deve dialogar com a realidade concreta dos sujeitos, individuais e coletivos, articulados com a luta pela terra. Concluímos que a produção coletiva do saber em parceria com educandos/as, educadores/as, comunidades e os movimentos sociais de luta pela terra, pode dialogar com histórias, memórias, identidades, desejos, valores e reconhecimento, fortalecendo o debate em torno da educação do campo, na sua estreita relação com movimentos sociais, escolas do campo e universidades públicas.

    1998-01-01

    Full Text Available OBJETIVO: Estudar as variáveis contempladas na Declaração de Nascimento (DN como possíveis fatores de risco para nascimentos pequenos para a idade gestacional (PIG e o retardo de crescimento intra-uterino como fator de risco para a mortalidade neonatal. MATERIAL E MÉTODO: As variáveis existentes na DN foram obtidas diretamente de prontuários hospitalares. Os dados referem-se a uma coorte de nascimentos obtida por meio da vinculação das declarações de nascimento e óbito, correspondendo a 2.251 nascimentos vivos hospitalares, de mães residentes, ocorridos no Município de Santo André, Região Metropolitana de São Paulo, no período de l/1 a 30/6/1992, e aos óbitos neonatais verificados nessa coorte. RESULTADOS: Obteve-se a proporção de 4,3% de nascimentos PIG, significativamente maior entre os recém-nascidos de pré-termo e pós-termo, entre os nascimentos cujas mães tinham mais de 35 anos de idade e grau de instrução inferior ao primeiro grau completo. Os recém-nascidos PIG apresentam maior risco de morte neonatal que aqueles que não apresentavam sinais de retardo de crescimento intra-uterino. CONCLUSÕES: Em áreas com menor freqüência de baixo peso ao nascer, é importante investigar a presença de retardo de crescimento intra-uterino entre os nascimentos prematuros e não apenas nos nascimentos de termo. O registro da data da última menstruação (ou da idade gestacional em semanas não agregadas na DN facilitaria a detecção de PIGs na população de recém-nascidos.

  11. Vaporizador artesanal de éter para cirurgia experimental em pequenos roedores

    Directory of Open Access Journals (Sweden)

    Marcus Vinicius Henriques Brito

    1998-01-01

    Full Text Available O presente trabalho descreve modelo experimental de vaporizador artesanal de éter, modificado a partir do modelo de WAYNFORTH & FLECKNELL, a fim de manter fluxo contínuo e homogêneo do anestésico em cirurgias onde se utiliza roedores de pequeno porte como animais de experimentação. O sistema é construído a partir de material encontrado em casas de materiais para aquários, sonda e tubo de ensaio de uso hospitalar, base de madeira e campânula de vidro confeccionada em vidraçaria. Como vantagens do sistema pode-se citar a manutenção do animal em plano anestésico sem que haja necessidade de contínuas "induções" com algodão embebido em éter e ofertado por via nasal, com perda do excesso para o meio ambiente e inalação do mesmo por quem conduz o experimento. Diminui-se assim quantidade de anestésico total gasto, devido manter-se níveis de oferta mais homogêneas por um fluxo contínuo de acordo com o plano anestésico do animal. Consegue-se também através do consumo aferido no tubo de ensaio, calcular aproximadamente o volume / minuto inalado, consumindo-se em média 5 ml de éter em uma hora de anestesia para ratos com 300g, obtendo com isto economia da substância, melhor controle da quantidade inalada pelo animal e redução da poluição do meio ambiente pelo mesmo.This paper described a homemade ether vaporizer, changed from WAYNFORTH & FLECKNELL model for small animals. The device is build with hospital material and products bought in aquarium’s shops. Their advantages are maintenance of anesthetic level without successive "inductions" by inhalatory nasal ether ; ether consumption of 5 ml per hour in animals with 300 g ; smaller ambient pollution and small cost. The disadvantages are a hardness and reduction of the plastic tubes after approximately 150 hour in use, by ether action and the necessity of experience acquisition in anesthetic manipulation with the device

    Full Text Available Este estudo teve por objetivo reconstituir as mudanças paleoambientais e paleohidrológicas no baixo Amazonas. Um testemunho de sedimento foi coletado no Lago Santa Ninha, na várzea do Lago Grande de Curuai, localizada na margem direita do Rio Amazonas a aproximadamente 850 km da foz. O teor de água, a granulometria, as datações com carbono 14, os conteúdos de carbono orgânico e nitrogênio total e o isótopo estável do carbono (δ13C foram utilizados para determinar os processos sedimentares a que o meio esteve submetido. O testemunho estudado possui 270 cm de comprimento que corresponde a um período de 5600 anos cal AP. Este estudo colocou em evidência diferentes ambientes sedimentares: na base do testemunho até 4900 anos cal AP há uma vegetação inundada que foi gradualmente substituida por bancos de gramíneas e por uma planicie com secas sazonais em 4000 anos cal AP até alcançar, desde 600 anos AP as condições atuais deste lago. Estas alterações podem ter ocorrido em decorrência de mudanças no ciclo hidrológico do Rio Amazonas que, por sua vez, também são reflexos de alterações climáticas.Physical, chemical and geochemical characteristics of lacustrine sediments were studied to reconstruct paleohydrologyical control on sedimentation in an Amazonian floodplain. A core was collected at the Lago Grande de Curuai floodplain, in the Santa Ninha Lake, located on the right margin of the Amazon River at 850 km of the estuary. Water content, granulometry, radiocarbon dating, organic carbon, nitrogen content and δ13C were used to characterize the sedimentary processes. The core is 270 cm-long which corresponds to 5600 cal years BP. The core points out different sedimentary environments: flooded vegetation at the base of the core till 4900 cal years BP is substituted by grass banks changing to a floodplain encompassing prolonged annual dryness at 4000 cal years BP.

    Full Text Available O presente projeto de pesquisa teve como objetivo principal apontar o sistema de coleta seletiva como uma alternativa viável para a busca da Gestão Integrada e Sustentável dos Resíduos Sólidos Urbanos no município de Pirambu/SE. Esta proposta visou valorizar e favorecer as possibilidades de reutilização e reciclagem dos resíduos sólidos; gerar renda para populações excluídas, minimizar problemas de ordem sanitária, reduzir impactos ambientais, sensibilizar a comunidade quanto à educação ambiental. Tudo isto conforme preconiza a atual legislação de resíduos sólidos, Lei Federal nº 12.305/2010, que obriga os municípios a implantarem a coleta seletiva no prazo máximo de quatro anos. Foram aplicados questionários junto à população local, como também, foram realizadas entrevistas com gestores responsáveis.  Comprovou-se a complexidade do gerenciamento de resíduos em um município, mesmo que este seja de pequeno porte. A adoção de uma política de gerenciamento sustentável para o tratamento e destinação final dos resíduos sólidos urbanos deve assegurar a melhoria continuada do nível de qualidade de vida da população e a implantação de um plano de coleta seletiva em Pirambu pode ser o primeiro passo para esta conquista.

    2016-08-01

    This cross-sectional study was undertaken to determine the prevalence of asymptomatic bacteriuria (ASB), the commonest bacterial isolates and the antibiotic sensitivity pattern among 556 pregnant women in Lagos University Teaching Hospital (LUTH), Nigeria. Women with a bacterial count over 100,000 colony-forming units per millilitre of the same organisms in paired urine samples were considered to have ASB. The prevalence of ASB was 14.6%. Klebsiella was the commonest micro-organism (39.2%) isolated. ASB was significantly associated with marital status, body mass index and parity. There was a significant relationship between urinary nitrites and ASB. The isolated organisms showed remarkable resistance to commonly prescribed antibiotics such as amoxicillin, cloxacillin and trimethoprim but good sensitivity to ofloxacin, gentamycin and ceftazidime. These facts have implications for the management of ASB in pregnancy.

    Use of ionising radiation in diagnostic radiography could lead to hazards such as somatic and genetic damages. Compliance to safe work and radiation protection practices could mitigate such risks. The aim of the study was to assess the knowledge and radiation protection practices among radiographers in Lagos, Nigeria. The study was a prospective cross sectional survey. Convenience sampling technique was used to select four x-ray diagnostic centres in four tertiary hospitals in Lagos metropolis. Data were analysed with Epi- info software, version 3.5.1. Average score on assessment of knowledge was 73%. Most modern radiation protection instruments were lacking in all the centres studied. Application of shielding devices such as gonad shield for protection was neglected mostly in government hospitals. Most x-ray machines were quite old and evidence of quality assurance tests performed on such machines were lacking. Radiographers within Lagos metropolis showed an excellent knowledge of radiation protection within the study period. Adherence to radiation protection practices among radiographers in Lagos metropolis during the period studied was, however, poor. Radiographers in Lagos, Nigeria should embrace current trends in radiation protection and make more concerted efforts to apply their knowledge in protecting themselves and patients from harmful effects of ionising radiation.

    Full Text Available A fruticultura é uma atividade de grande importância na balança comercial brasileira e mais ainda para a região Nordeste. As diversas exigências do mercado exportador de frutas, como os certificados de qualidade, aliadas aos entraves internos da produção e da comercialização, entre os quais a ausência de padronização dos produtos e a falta de crédito, fizeram da intermediação das exportações uma prática regular. Grandes empresas, cooperativas, associações e ONG’s recebem as produções de muitos pequenos produtores e as exportam, conjuntamente com sua própria produção, quando também produzem. No Nordeste, é comum o agente exportador oferecer contratos de exportação aos produtores que incluem assistência técnica, administrativa e jurídica e os insumos necessários à produção. Este trabalho formula uma proposta de modelagem, usando a teoria dos jogos, mais especificamente a abordagem Principal-Agente, para os contratos de exportação entre produtores e exportadores da fruticultura. Aplicou-se a proposta para os pequenos produtores de manga do Rio Grande do Norte, e mostrou-se que a escolha do tipo de contrato da maioria dos produtores é ótima para ambas as partes e que estes contratos incentivam o produtor a aplicar esforço elevado na produção. Extensões da modelagem proposta podem incluir barganha nas negociações ou considerar um modelo de jogo dinâmico.Fruit production is an activity of great importance in the Brazilian commercial balance and even more in the Northeastern region. Intermediation is a regular practice in the fruit exporting market due to existence of requirements, such as quality certificates, and of internal problems in production and commercialization, such as credit limitations and absence of product standardization. Large companies, cooperatives, associations and NGOs receive products from many small producers and export them together with their own products. In Northeast, it is

    Full Text Available Resumo Resumo Em municípios de pequeno porte, que em geral são situados em áreas geográficas mais isoladas, combinado com situações de maior vulnerabilidade social e econômica, a escassez de médicos é um problema constante. O objetivo deste estudo foi identificar a participação e as características dos municípios de pequeno porte da macrorregião norte do estado do Paraná que aderiram ao Projeto Mais Médico para o Brasil (PMMB. Trata-se de um estudo quantitativo realizado em 82 municípios que utilizou dados primários e secundários. Os resultados revelaram que eram poucos os municípios que possuíam algum critério de adesão (6,1%, mas isso não representou um impedimento para que os demais aderissem ao projeto (75,6%. Os municípios que possuíam menores índices de desenvolvimento humano, que tinham população de mais de cinco mil habitantes, algum critério de adesão e que eram mais afastados, seja da sede da região, seja do município de médio/grande porte mais próximo foram os que mais aderiram ao PMMB. Não se pode negar que o PMMB reduziu de forma significativa a distribuição desigual de médicos no Brasil e na região de estudo. Contudo, a sustentabilidade dessa política precisa estar atrelada ao enfrentamento de outros desafios que ainda persistem no SUS.

    Full Text Available Water is a nutrient of extreme importance for animals and must be considered vital in any rearing phase. The increasing scarcity of this precious natural resource has concerned different segments of society in order to find solutions for rational and sustainable use of this nutrient. Small ruminants, especially sheep and goats, have social and economic importance due to their great ability in adapting to adverse environmental conditions and using water efficiently. Thus, they might be a good alternative to mitigate the climate change effects and to generate foreign exchange and improving life condition in many places of the world. The concept of water productivity for livestock production is relatively new and there are few studies in the world, especially in Brazil. More researches and new technologies for water use in livestock production are indispensable.A água é um nutriente extremamente importante na vida dos animais e deve ser considerada como vital em qualquer fase da criação. A escassez crescente deste precioso recurso natural tem provocado reações de diferentes segmentos da sociedade na busca de soluções de uso racional e sustentável deste nutriente. Os pequenos ruminantes, especialmente os ovinos e caprinos, são partes importantes da vida econômica e social de muitas nações pela sua ampla capacidade de adaptação às condições adversas do ambiente e boa eficiência no uso da água, podendo ser uma das boas alternativas de mitigação dos efeitos das mudanças climáticas, gerando divisas e melhoria das condições de vida em muitas regiões do mundo. O conceito de produtividade de água para a produção animal é relativamente novo e ainda são recentes e escassos os estudos existentes no mundo e em particular no Brasil. A realização de mais pesquisas e a geração de novas tecnologias de uso da água na produção animal, hoje mais do que nunca tornam-se imprescindíveis.

    Full Text Available Dialogar a respeito dos modos de subjetivação presentes na sociedade contemporânea é um processo que atravessa os debates do campo pedagógico. A partir dessa abertura foi possível avançar na compreensão de que os instrumentos midiáticos são potentes construtores de formas específicas de ser e de estar desse tempo. No entanto, discutir como os discursos que veiculam nos filmes, reproduzidos nas escolas de Ensino Básico, subjetivam os estudantes e reafirmam formas de exclusão institucionalizadas socialmente é uma trajetória recente no âmbito das pesquisas da prática pedagógica. O presente ensaio propõe-se a apresentar algumas sutilezas encontradas no episódio “O planeta do tempo – primeira parte”, da série de desenho animado O Pequeno Príncipe, apresentada pelo canal da televisão a cabo Discovery Kids, que nos permite perceber a agenda específica intrínseca neste desenho animado, bem como alguns aspectos sociais reproduzidos.

  3. Vulnerabilidade à eutrofização de dois lagos tropicais de climas úmido (Cuba e semiárido (Brasil

    Full Text Available RESUMO: Este artigo compara o estado de eutrofização e suas prováveis causas em dois reservatórios tropicais, um em clima úmido (La Juventud, Cuba e o outro em clima semiárido (Marengo, Brasil. Após estimar o estado trófico dos dois reservatórios nas estações chuvosa e seca, avaliou-se a influência hidrológica e de uso do solo sobre o grau de trofia dos lagos. Concluiu-se que os lagos são, em média, mesotróficos. Porém, o lago tropical semiárido encontra-se eutrófico, enquanto que o úmido está oligotrófico. Considerando que há similitude entre os usos do solo nas duas bacias e que, na estação chuvosa, o aporte de nutrientes na bacia úmida é consideravelmente superior ao da semiárida, o maior estado trófico da bacia seca surpreende. A variável que melhor explica esse fenômeno é o tempo de residência da água, que influencia diretamente o tempo de residência do fósforo no lago. O elevado tempo de residência da água na bacia semiárida (três vezes superior ao do lago úmido deve-se tanto ao reduzido coeficiente de escoamento superficial (93 versus 595 mm anuais na bacia úmida quanto à excessiva evaporação da água armazenada no reservatório seco (quatro vezes superior à do reservatório úmido. Esses resultados indicam que lagos semiáridos são mais vulneráveis à eutrofização que os úmidos nos períodos de estio e que, portanto, o manejo de suas bacias deve ser mais restritivo à produção de nutrientes.

  5. USO DE RECEPTORES GPS DE 100 HZ NA DETECÇÃO DE DEFLEXÕES VERTICAIS MILIMÉTRICAS DE PONTES DE CONCRETO DE PEQUENO PORTE

    Directory of Open Access Journals (Sweden)

    ANA PAULA CAMARGO LAROCCA

    Full Text Available As últimas quatro décadas foram importantes para o desenvolvimento da malha rodoviária brasileira. O país recebeu incentivos financeiros para a sua expansão e diversas soluções estruturais para pontes e viadutos foram criadas. Em paralelo a este desenvolvimento, houve nos últimos anos um crescimento significativo dessas estruturas em estágio avançado de deterioração devido à ausência de programas de manutenção preventiva. Dessa maneira, este trabalho propõe o uso de receptores GPS num plano de monitoramento de curta duração para acompanhar o comportamento estrutural de uma ponte rodoviária curva de concreto armado já em serviço. E apresenta os primeiros resultados da pesquisa com a portadora L1 do sistema GPS e dados gravados com taxa de 100 Hz, no monitoramento do vão central de ponte de concreto de pequeno porte situada sobre o Rio Jaguari, na cidade de Extrema, divisa entre os Estados de Minas Gerais e São Paulo. O desafio reside no fato de que estruturas como estas - pontes de concreto de pequeno e médio porte - respondem pela grande maioria das obras de arte da malha rodoviária brasileira e por serem estruturas rígidas, apresentam deflexões verticais pequenas, de até 5mm. O experimento foi realizado por meio de sessões de observações com receptores GPS sobre a ponte, no vão instrumentado por equipamentos convencionais para posterior confrontação de resultados entre os receptores GPS e os métodos clássicos de monitoramento. A ferramenta de filtragem Continuos Wavelet Transform (CWT foi utilizada para analisar as frequências de resposta da ponte a partir dos resíduos da dupla diferença de fase da portadora L1. A análise do espectro de energia da CWT gerado a partir dos dados coletados com os receptores GPS indicou alta concentração de energia nas mesmas faixas de frequência - de resposta do tabuleiro da ponte - apontadas pela Modelagem por Elementos Finitos e pela prova de carga dinâmica.

    Full Text Available JUSTIFICATIVA E OBJETIVOS: A avaliação pré-operatória tem como objetivos diminuir a morbimortalidade do paciente cirúrgico, o custo do atendimento perioperatório e a ansiedade pré-operatória. A partir da avaliação clínica deve-se definir a necessidade de exames complementares e estratégias para reduzir o risco anestésico-cirúrgico. O objetivo deste trabalho foi avaliar o benefício de exames de rotina pré-operatório de pacientes de baixo risco em cirurgias de pequeno e médio porte. MÉTODOS: Trata-se de um estudo descritivo, transversal, com 800 pacientes atendidos no consultório de avaliação pré-anestésica do Hospital Santo Antonio, Salvador, BA. Foram incluídos pacientes de 1 a 45 anos, estado físico ASA I, que seriam submetidos a cirurgias eletivas de pequeno e médio porte. Avaliaram-se alterações no hemograma, coagulograma, eletrocardiograma, RX de tórax, glicemia, função renal e dosagem de sódio e potássio e as eventuais mudanças de conduta que ocorreram decorrentes dessas alterações. RESULTADOS: Dos 800 pacientes avaliados, 97,5% fizeram hemograma, 89% coagulograma, 74,1% eletrocardiograma, 62% RX de tórax, 68% glicemia de jejum, 55,7% dosagens séricas de ureia e creatinina e 10,1% dosagens de sódio e potássio séricos. Desses 700 pacientes, 68 (9,71% apresentaram alteração nos exames pré-operatórios de rotina e apenas 10 (14,7% dos considerados alterados tiveram conduta pré-operatória modificada, ou seja, solicitação de novos exames, interconsulta ou adiamento do procedimento. Nenhuma das cirurgias foi suspensa. CONCLUSÃO: Observou-se que excessivos exames complementares são solicitados no pré-operatório, mesmo em pacientes jovens, de baixo risco cirúrgico, com pouca ou nenhuma interferência na conduta perioperatória. Exames aboratoriais padronizados não são bons instrumentos de screening de doenças, além de gerar gastos elevados e desnecessários.

    Full Text Available Em contraposição às hipóteses para sustentação dos modelos financeiros "clássicos", como o Capital Asset Pricing Model (CAPM de Sharpe-Litner-Mossin, a literatura recente de Finanças tem documentado que algumas características das empresas se mostram relevantes para explicar retornos esperados. Este artigo tem por objetivo analisar se o tamanho da empresa no Brasil é uma característica importante para explicar uma outra dimensão da relação risco versus retorno: a volatilidade. Como metodologia, procedeu-se a uma reestruturação completa do índice IBrX da Bolsa de Valores de São Paulo (Bovespa, obtendo-se dois novos índices: um de empresas com grande porte e outro de empresas com pequeno porte. A partir dos índices construídos, analisaram-se o comportamento e a estrutura a termo da volatilidade, com ajustes dos modelos GARCH (1,1 e TARCH (1,1. Em linhas gerais, pode-se concluir que o comportamento e a estrutura a termo da volatilidade de empresas de grande e pequeno porte são diferentes, o que permite a incorporação da característica tamanho da empresa nas funções financeiras, tais como decisões de investimentos, precificação de títulos e gerenciamento de risco.Recent finance literature states that certain company characteristics are relevant to explain the returns expected, which is contrary to classic financial models such as the Capital Asset Pricing Model. The effect of company size in Brazil was investigated to verify if it explains another aspect of the relationship of risk versus return, which is volatility. The method used was to restructure the IBrX index (Sao Paulo Stock Exchange - Bovespa to obtain a new index for large sized companies and also another for small companies. The behavior and term structure of volatility was analyzed using adjustments of the GARCH (1.1 and TARCH (1.1 models for each of the two new indices.

    Introduction Injuries are the third most important cause of overall deaths globally with one-quarter resulting from road traffic crashes. Majority of these deaths occur before arrival in the hospital and can be reduced with prompt and efficient prehospital care. The aim of this study was to highlight the burden of road traffic injury (RTI) in Lagos, Nigeria and assess the effectiveness of prehospital care, especially the role of Lagos State Ambulance Service (LASAMBUS) in providing initial care and transportation of the injured to the hospital. A three-year, retrospective review of road traffic injured patients seen at the Surgical Emergency Room (SER) of the Lagos State University Teaching Hospital (LASUTH), Ikeja, Nigeria, from January 1, 2012 to December 31, 2014 was conducted. Parameters extracted from the Institution Trauma Registry included bio-data, date and time of injury, date and time of arrival in SER, host status, type of vehicle involved, and region(s) injured. Information on how patients came to the hospital and outcome in SER also were recorded. Results were analyzed using Statistical Package for Social Sciences (SPSS; IBM Corporation; Armonk, New York USA) version 16. A total of 23,537 patients were seen during the study period. Among them, 16,024 (68.1%) had trauma. Road traffic crashes were responsible in 5,629 (35.0%) of trauma cases. Passengers constituted 42.0% of the injured, followed by pedestrians (34.0%). Four wheelers were the most frequent vehicle type involved (54.0%), followed by motor cycles (30.0%). Regions mainly affected were head and neck (40.0%) and lower limb (29.0%). Less than one-quarter (24.0%) presented to the emergency room within an hour, while one-third arrived between one and six hours following injury. Relatives brought 55.4%, followed by bystanders (21.4%). Only 2.3% had formal prehospital care and were brought to the hospital by LASAMBUS. They also had significantly shorter arrival time.

    Full Text Available The ovarian remnant syndrome (ORS is an iatrogenic disorder in bitches and queens, which is characterized by recurrence of estrus following surgical spay, due to the presence of a piece of ovarian tissue within the abdominal cavity. In most cases, the remnant ovary is found in the right ovarian pedicle, due to its topographic position, deeper and more cranial than the left ovary. The main clinical signs of ORS in small animals are the heat behavior and the presence of vaginal swelling/secretion, especially in canines. The diagnosis should be performed by means of vaginal cytology when attraction of males is detected, serum estrogen and progesterone levels and/or by challenging test with GnRH or hCG administration. However, vaginal citology is the most suitable and less expensive diagnostic tool. Nowadays the treatment of choice is a new laparotomy or laparoscopy, followed by removal of the remnant ovarian tissue. The surgical treatment has more chances of success if it is performed in the diestrus (i.e., between 15 and 60 days after the detection of attraction of males. Furthermore, a careful and accurate surgical procedure aided by advanced visualization techniques during ovariohysterectomy or ovariectomy is the best way to prevent ORS in companion animals. A síndrome do ovário remanescente (SOR é um distúrbio iatrogênico em cadelas e gatas caracterizado pelo retorno do estro após contracepção cirúrgica devido à presença de fragmento de tecido ovariano na cavidade abdominal. Frequentemente, o ovário remanescente está situado no pedículo ovariano direito, sobretudo devido a sua posição topográfica mais profunda e cranial em comparação ao ovário esquerdo. Os principais sinais clínicos de SOR em pequenos animais são cio e presença de edemaciamento/secreção vulvar/vaginal, especialmente em caninos. O diagnóstico deve ser realizado por meio de citologia vaginal quando detecta-se o interesse dos machos pela cópula com a f

The descriptive research survey was used in order to assess the opinions of the respondents using the questionnaire. A total of 84 samples were used as representative population, while two null hypotheses were formulated and tested using the Pearson Product Moment Correlation Coefficient at 0.05 level of significant. The results that were obtained indicated that a positive correlation exists between frequency of   travel and commuters income in Lagos Metropolis and also that a positive correlation exists between frequency of travel and distance covered by commuters in Lagos Metropolis. Secondary data was also sourced to serve as complement to the primary data, thus allowing for a robust research. Descriptive statistical tools such as percentages were also adopted to present the socio-economic characteristics in the area. Findings showed that about 57% of sampled population are male, 62 % are civil servants, 48% of respondents travel for business purposes. Also, that majority of the respondents (50% said that the commercial public transport is highly prone to accident, while about 64% of the respondents commute on daily basis. It was established that lack of transport infrastructure coupled with poor road maintenance were seen as the leading causes of inaccessibility of the area.

    Halitosis is defined as a noticeable unpleasant odor from the mouth. It is a medico-social problem that affects a significant number of people around the world. Research reveals that nearly 50% of the adult population has halitosis. To determine level of awareness of halitosis and prevalence of the condition amongst students in tertiary institutions as a baseline survey. For this project, 100 students from three tertiary institutions in Lagos state were chosen: University of Lagos, Lagos State University, Ojo campus and Yaba College of Technology. A semi-structured questionnaire and practical testing/diagnostic tool were utilized. Data collected was collated and analyzed using Microsoft Excel 2007 and SPSS statistical software. Most of the respondents were single and Christian. Level of awareness of halitosis was high. Results showed that 15%, 2% and 22% from UNILAG, LASU and YCT respectively said they had halitosis. Using the diagnostic tool, 6%, 8% and 2% respectively were positive for halitosis. There is high level of awareness of halitosis among the respondents. The prevalence of the disorder is low, however, it is recommended that enlightenment campaigns be mounted in schools to improve level of awareness and treatment seeking.

    Full Text Available Este trabalho apresenta um estudo para aerogerador de pequeno porte projetado para uso residencial. A ênfase está na modelagem e simulação virtual da estrutura das pás em compósito de fibra de vidro. A modelagem foi feita com software para desenho assistido por computador (CAD 3D. Para o projeto, foi escolhido o perfil MH110 que apresenta boa relação entre coeficiente de sustentação e coeficiente de arrasto e facilidade de fabricação. Os parâmetros como o diâmetro do rotor, a corda e a torção da pá, as relações entre velocidades e a aplicação de cargas na estrutura do material utilizado foram definidos segundo bibliografia específica, software para análise de perfil aerodinâmico e simulações pelo método dos elementos finitos. Procurou-se buscar sempre a maior eficiência, segurança e economia. O material foi projetado para resistir às tensões decorrentes de operação em condições consideradas normais e para rajadas de vento. A simulação pelo método dos elementos finitos foi conduzida com ferramenta computacional e levou em conta os limites de falha do material utilizado. A geometria foi simulada sem reforço interno e apresentou baixo deslocamento quando submetida às cargas aerodinâmicas de empuxo e rotacional. Ao realizar simulação com critério de falha, foi possível determinar a espessura mais adequada para o material compósito e verificar seu comportamento de acordo com diferentes velocidades de vento.

    Lago La Plata dam is located between the municipalities of Naranjito and Toa Alta in north central Puerto Rico, about 5 kilometers south of the town of Toa Alta and about 5 kilometers north of the town of Naranjito. The reservoir impounds the waters of the Rio de La Plata, the Rio Guadiana, and the Rio Ca?as, and is part of the San Juan Metropolitan Water District, which provides about 35 percent of the total water demand for the area (Soler-Lopez and others, 2000). The reservoir has a drainage area of about 469 square kilometers. The dam was constructed in 1974 and is a concrete gravity structure with a normal pool elevation of 52.00 meters above mean sea level (Puerto Rico Electric Power Authority, 1979). During October 1998, the U.S. Geological Survey (USGS), Caribbean Water Science Center, in cooperation with the Puerto Rico Aqueduct and Sewer Authority (PRASA) conducted a bathymetric survey of Lago La Plata to assess the impact of Hurricane Georges on the storage capacity of the reservoir. Between July 17 and 20, 2006, the USGS and the PRASA conducted an additional bathymetric survey of Lago La Plata to update the reservoir storage capacity and determine the reservoir sedimentation rate by comparing the 2006 survey data with the 1998 survey data.. The purpose of this report is to update the reservoir storage capacity, sedimentation rates, and areas of substantial sediment accumulation since 1998. Historical (1974) data are referenced as needed to account for long-term storage capacity loss trends...

    2008-07-01

    Lagos bat virus (LBV) belongs to genotype 2 of the Lyssavirus genus. The complete nucleoprotein (N), phosphoprotein (P), matrixprotein (M) and glycoprotein (G) genes of 13 LBV isolates were sequenced and phylogenetically compared with other lyssavirus representatives. The results identified three different lineages of LBV. One of these lineages demonstrated sufficient sequence diversity to be considered a new lyssavirus genotype (Dakar bat lyssavirus). The suggested quantitative separation of lyssavirus genotypes using the N, P, M and G genes was also investigated using P-distances matrixes. Results indicated that the current criteria should be revised since overlaps between intergenotypic and intragenotypic variation occur.

    Full Text Available RESUMO: Buscamos desenvolver aspectos de pesquisa que se debruçou sobre o acompanhamento de um grupo de professores no que denominamos Pequenos Grupos de Pesquisa (PGP em escolas públicas de educação básica. Esse acompanhamento propiciou elementos que foram interpretados de acordo com a teoria da ação comunicativa, o que possibilitou a compreensão de um modelo de formação. O trabalho foi orientado de acordo com a pesquisa participante, cuja potencialidade se configurou no processo colaborativo de interação universidade-escola, que propiciou a formação e transformações em ambas as esferas. Dessa junção, resultaram relações entre os agentes da universidade e da escola que foram homogêneas. Por fim, pudemos inferir que os processos de interação que se propõem formativos e investigativos podem passar por momentos de problematização, ação comunicativa e consenso, para que a universidade se aproxime dos ideais de igualdade para com os professores da educação básica.

    Full Text Available Étroitement liées à la pulsation saisonnière des crues de l’Amazone, les activités des petits paysans et pêcheurs des várzeas sont particulièrement sensibles aux manifestations plus extrêmes de la variabilité hydrologique. Ce travail propose d’appréhender la vulnérabilité de ces communautés riveraines aux crues et étiages extrêmes autour du Lago Janauaca, près de Manaus, dans un contexte climatique d’intensification du cycle hydrologique. Dans un premier temps nous proposons de caractériser la variabilité hydrologique du Rio Solimões et son impact spatial sur le Lago. Si l’extension du phénomène est frappante, les dynamiques anthropiques sur les rives du lac sont elles aussi importantes. Celles-ci s’expliquent plus par l’ouverture de pistes entre le lac et la BR319, que par l’expansion des cultures traditionnelles qui restent modérée. Enfin, une série d’entretiens menés auprès des riverains dévoile une relation complexe entre les différentes activités des populations et les extrêmes hydrologiques. Les sécheresses y apparaissent comme les perturbations majeures, non seulement à cause de leurs impacts sur les cultures, mais surtout en raison des difficultés qu’elles entraînent pour les mobilités locale et régionale.Intimamente relacionado com o pulso de inundação sazonal do rio Amazonas, as atividades dos agricultores e pescadores das várzeas são particularmente sensíveis aos eventos mais extremos da variabilidade hidrológica. Este artigo tem como objetivo analisar a vulnerabilidade das comunidades ribeirinhas às cheias e às estiagens extremas ao redor do Lago Janauaca, próximo de Manaus, em um contexto de intensificação do ciclo hidrológico.

This study was carried out to assess body iron stores in regular blood donors. Methods: A total of 52 regular (study and 30 first-time (control volunteer blood donors were studied prospectively. Twenty milliliters of venous blood was drawn from each subject, 5 mL of which was put into sodium ethylenediamine tetra-acetic acid specimen bottles for a full blood count, including red blood cell indices. The remaining sample was allowed to clot in a plain container, and the serum was then retrieved for serum ferritin, serum iron, and serum transferrin receptor measurement by enzyme-linked immunosorbent assay. Results: Mean hemoglobin and packed cell volume in the study group (13.47 ± 2.36 g/dL and 42.00 ± 7.10, respectively, P = 0.303 were not significantly higher than in the control group (12.98 ± 1.30 g/dL and 39.76 ± 4.41, respectively, P = 0.119.

    Full Text Available Este artigo objetivou revisar as informações recentes sobre mastite em pequenos ruminantes, abrangendo etiologia, epidemiologia, aspectos de controle e profilaxia. Houve a preocupação em reunir resultados de estudos desenvolvidos no Brasil, uma vez que a mastite tem a interferência de uma série de fatores, como fatores ambientais e outros decorrentes dos sistemas de manejo empregados, condições essas determinantes para etiologia e epidemiologia da enfermidade. A prevalência da mastite em caprinos varia entre 22 e 75%, sendo que os casos de mastite subclínica são os mais frequentes. Existe uma carência de trabalhos voltados para os aspectos epidemiológicos da enfermidade no nosso país. Contudo, observa-se que a mastite vem assumindo importância cada vez maior nos rebanhos voltados para produção de carne, sendo encontrados resultados de pesquisa, principalmente na espécie ovina. A mastite estafilocócica corresponde à maior fração nas infecções intramamárias em pequenos ruminantes. O caráter zoonótico de alguns patógenos, a exemplo do Staphylococcus aureus ressalta a importância da implantação de programas de controle em propriedades leiteiras. Algumas das ferramentas de diagnóstico ainda necessitam de padronização, principalmente para espécie caprina que apresenta uma série de particularidades. Ainda são discutidas as principais estratégias de controle como o manejo de fêmeas e suas crias, os procedimentos de ordenha e a utilização de vacinas.The present reviews mastitis in small ruminants, focusing important aspects of etiology, epidemiology, diagnose, control, and prophylaxis. There was a special concern in review studies developed in Brazil, since mastitis results from a combination of many factors such as environmental and management conditions that concur for the action of etiological agents and for the epidemiology of this relevant disease.

    A survey of healthcare waste management practices and their implications for health and the environment was carried out. The study assessed waste management practices in 20 healthcare facilities ranging in capacity from 40 to 600 beds in Ikorodu and metropolitan Lagos, Lagos State, Nigeria. The prevailing healthcare waste management status was analysed. Management issues on quantities and proportion of different constituents of waste, segregation, collection, handling, transportation, treatment and disposal methods were assessed. The waste generation averaged 0.631 kg bed(-1) day(-1) over the survey area. The waste stream from the healthcare facilities consisted of general waste (59.0%), infectious waste (29.7%), sharps and pathological (8.9%), chemical (1.45%) and others (0.95%). Sharps/pathological waste includes disposable syringes. In general, the waste materials were collected in a mixed form, transported and disposed of along with municipal solid waste with attendant risks to health and safety. Most facilities lacked appropriate treatment systems for a variety of reasons that included inadequate funding and little or no priority for healthcare waste management as well as a lack of professionally competent waste managers among healthcare providers. Hazards associated with healthcare waste management and shortcomings in the existing system were identified.

    Full Text Available Aglomerações de animais em eventos comerciais do tipo feiras de negócios representam um importante elo na transmissão de doenças infecciosas, resultando na importância do conhecimento acerca da epidemiologia das doenças de pequenos ruminantes. Desta forma, o objetivo desse estudo foi determinar a presença das lentiviroses em caprinos e ovinos comercializados na feira de animais da cidade de Tabira, Sertão de Pernambuco, bem como a identificação de possíveis fatores de risco associados à enfermidade. Foram coletadas amostras de soro de 233 caprinos e 119 ovinos, sem raça definida, pertencentes a doze proprietários, na feira de animais vivos do município no período de novembro de 2014 a junho de 2015. Foi aplicado questionário epidemiológico para análise dos fatores de risco. O diagnóstico da infecção por Lentivirus de Pequenos Ruminantes (LVPR nas espécies foi realizado pela Imunodifusão em ágar-gel (IDGA e Western Blotting (WB. Na IDGA foram utilizados antígenos de Vírus Maedi-visna (MVV para ovinos e de vírus da Artrite-Encefalite Caprina (CAEV, cepa CAEV- Cork para caprinos, e no WB foi utilizado a cepa CAEV- Cork como antígeno para ambas espécies. As variáveis obtidas no questionário foram submetidas a análises estatísticas univariada e multivariada. Pela técnica de IDGA foi possível identificar um caprino soropositivo. Não foi detectada positividade nos ovinos. No WB 15/233 (6,44%; IC95% = 3,94 - 10,35% caprinos e 8/119 (6,72%; IC95% = 3,45 - 12,71% ovinos foram soropositivos, totalizando 23/352 (6,53%; IC95% = 4,39 - 9,61% animais reagentes.

    Para a maioria dos estudantes, sua passagem pelo ensino formal fundamental envolve a transmissão de fatos que devem ser guardados para um exame, a habilidade para lembrar fórmulas e, eventualmente, a repetição de experimentos que devem produzir resultados exigidos pelo professor. O resultado deste modelo de ensino, ao longo dos anos, é conhecido por todos: desconhecimento e descontentamento, por parte dos estudantes, de temas relativos ao papel e aos processos da ciência. Acreditamos que a Astronomia, pelo seu caráter observacional, é uma das áreas do conhecimento que pode contribuir neste cenário. A Fundação Planetário da Cidade do Rio de Janeiro possui um telescópio Meade LX-200 (25cm) que, juntamente com as câmeras CCD ST-7E e ST8E, tem sido utilizado em projetos voltados aos estudantes do ensino médio desde o ano 2000. Tais projetos envolvem a condução de um projeto de pesquisa observacional num nível apropriado, e possibilitam o contato com técnicas e novas tecnologias: computador, software para manipulação de dados e gráficos, programas de tratamento e redução de dados, uso de equipamentos óptico-eletrônicos (telescópio e CCD), bem como o processo de aquisição de conhecimento. Dentro da proposta dos anos anteriores, priorizamos projetos de uma noite, ou seja, procuramos trabalhar com fenômenos que apresentem variabilidade com intervalo de recorrência relativamente curto. Em todos os casos, optamos pela fotometria diferencial, que tem se mostrado bastante eficiente para o céu luminoso como o da cidade do Rio de Janeiro. Neste painel, apresentamos alguns dos projetos desenvolvidos no último ano, com 25 estudantes.

    Full Text Available A globalização propiciou mudanças de hábitos, de consumo, de produção de bens, de serviços e de conhecimento. A contabilidade, ferramenta imprescindível para a tomada de decisão empresarial e governamental, é parte inerente nesse contexto em virtude, principalmente, do seu papel social. Nesse cenário, o Governo Federal instituiu, por meio do Decreto nº 6.022, de 22 de janeiro de 2007, o Sistema Público de Escrituração Digital (SPED que, dentre seus subprojetos, propõe a Nota Fiscal Eletrônica (NF-e, processo eletrônico de emissão de notas fiscais que utiliza a Tecnologia de Informação para reduzir as despesas com papel e armazenagem de documentos, e contribui para a diminuição das obrigações acessórias. A presente pesquisa objetivou analisar os impactos causados nas Microempresas (MEs e Empresas de Pequeno Porte (EPPs sediadas em Umuarama/PR, quanto à implantação da NF-e e a percepção dos gestores sobre os objetivos e benefícios preconizados pelo Governo Federal. Esta pesquisa, quanto à sua natureza, é classificada como aplicada, descritiva, indutiva, com caráter exploratório e de abordagem quanti-qualitativa. O instrumento de pesquisa e levantamento de dados adotado foi um questionário semiestruturado com perguntas abertas e fechadas, aplicado em setembro de 2011 com uma amostra de pesquisa composta por trinta empresas do município escolhido. Os resultados apontam que os principais impactos sofridos com a implantação da NF-e foram: mudança de processos internos, necessidade de investimentos em tecnologia e aumento nos custos totais, bem como a divergência parcial do preconizado pelo Governo Federal no que concerne à percepção do empresariado relativamente aos objetivos e benefícios da ferramenta.

Quando sons, cores e luzes, falas, enquadramentos, gestos e movimentos devem contar a história, articulam-se aproximações e afastamentos em relação às cadeias significantes de sua correspondente no mundo das letras. Pelo método do comparativismo, este trabalho identifica em O Pequeno Príncipe exemplos de convergência e de divergência entre as cadeias significantes da obra literária – escrita por Antoine de Saint-Exupéry, em 1940 – e de sua versão cinematográfica, rodada em 1974, sob direção de Stanley Donen. De modo geral, as análises apontam que trechos literários com descrições muito pormenorizadas são de difícil transposição para a narrativa fílmica, o que condiciona a utilização de elipses. Nesse sentido, plots com menos implicações no conjunto da narrativa são mais facilmente descartados na versão cinematográfica. A questão temporal, que implica fundamentalmente no ritmo do produto audiovisual, é um dos fatores que mais obrigam o filme a determinados cortes em relação à narrativa literária. No entanto, o sentido geral da obra não parece ser alterado por esta condição. O afastamento entre os produtos das duas versões textuais destaca-se quando – numa evidente preocupação em manter o interesse de uma faixa de público mais ampla e massiva – o filme suprime algumas discussões de cunho mais profundamente filosófico, promovendo o fechamento de sentidos que, na versão literária, ficam em aberto.

    Full Text Available OBJETIVO: Estudar as variáveis contempladas na Declaração de Nascimento (DN como possíveis fatores de risco para nascimentos pequenos para a idade gestacional (PIG e o retardo de crescimento intra-uterino como fator de risco para a mortalidade neonatal. MATERIAL E MÉTODO: As variáveis existentes na DN foram obtidas diretamente de prontuários hospitalares. Os dados referem-se a uma coorte de nascimentos obtida por meio da vinculação das declarações de nascimento e óbito, correspondendo a 2.251 nascimentos vivos hospitalares, de mães residentes, ocorridos no Município de Santo André, Região Metropolitana de São Paulo, no período de l/1 a 30/6/1992, e aos óbitos neonatais verificados nessa coorte. RESULTADOS: Obteve-se a proporção de 4,3% de nascimentos PIG, significativamente maior entre os recém-nascidos de pré-termo e pós-termo, entre os nascimentos cujas mães tinham mais de 35 anos de idade e grau de instrução inferior ao primeiro grau completo. Os recém-nascidos PIG apresentam maior risco de morte neonatal que aqueles que não apresentavam sinais de retardo de crescimento intra-uterino. CONCLUSÕES: Em áreas com menor freqüência de baixo peso ao nascer, é importante investigar a presença de retardo de crescimento intra-uterino entre os nascimentos prematuros e não apenas nos nascimentos de termo. O registro da data da última menstruação (ou da idade gestacional em semanas não agregadas na DN facilitaria a detecção de PIGs na população de recém-nascidos.INTRODUCTION: Variables of birth certificates were analysed as risk factors of SGA (Small for Gestational Age infantis, and with a view to discovering if retarded intra-uterine growth was a risk factor neonatal mortality. MATERIAL AND METHOD: Data were obtained directly from 11 hospital medical records. A cohort of 2.251 hospital live births was obtained.

    Full Text Available O objetivo do estudo foi caracterizar a gestão da Assistência Farmacêutica, frente ao cenário da judicialização, em municípios de Mato Grosso do Sul. Foram visitadas as 27 comarcas de segunda entrância, e as informações referentes aos processos judiciais que demandavam medicamentos foram coletadas. Foram selecionados seis municípios para caracterizar a gestão da Assistência Farmacêutica através de entrevistas em profundidade com gestores. Foram identificadas deficiências graves nas atividades da Assistência Farmacêutica, possivelmente consolidando os problemas advindos dos pleitos judiciais, contrariando o que era esperado. Estima-se, assim, que a gestão incipiente da Assistência Farmacêutica nos municípios seria o principal determinante para o incremento das demandas.

    The basic operation, design and construction of the plastic scintillator detector is described. In order to increase the sensitivity of this detector, two blocks of plastic scintillator have been assembled to act as a anticompton system. The detectors were produced by polymerisation of styrene monomer with PPO (2,5 diphenyl-oxazole) and POPOP (1,4 bis (-5 phenyl-2- oxazoly)benzene) in proportions of 0.5 and 0.05 respectively. The transparency of this detector was evaluated by excitation of the {sup 241} Am source located directly in the back surface plastic coupled to a photomultiplier. The light attenuation according to the detector thickness has fitted to a two-exponential function: relative height pulse = 0,519 e{sup -0.0016} + 0.481 e{sup -0.02112.x}. Four radioactive sources{sup {sup 2}2} Na, {sup 54} Mn, {sup 137} Cs and {sup 131} I were used to evaluate the performance of this system. The Compton reduction factor, determined by the ratio of the energy peak values of suppressed and unsuppressed spectra was 1.16.

    Full Text Available Estate marketing is an aspect of the profession of Estate Surveying and Valuation in Nigeria. Previous studies on estate marketing identified that there are challenges affecting estate marketing and the resultant effect on these challenges affects the credibility of the profession of Estate Surveying and Valuation in Nigeria. This necessitates the need to examine the practice of estate marketing in Nigeria. This study examined estate marketing practice among estate surveyors and valuers in Ikeja, Lagos Nigeria. The sample size for the study is the 64 registered Estate Surveying and Valuation firms in the study area. Data gathered were analyzed using descriptive statistics and 5-point likert ordinal scale. Findings from the study revealed that the use of brochure or bulletin is the most common estate marketing method in the study area. Also, it was revealed from the study that the use of press is the most cost effective method of estate marketing in the study area. The study identified the various challenges of estate marketing. However, collection of double professional fees is the most prevalent challenge of estate marketing in the study area. Finally, aggressive marketing which leads to unethical practices is the most prevalent mitigating measures adopted by Estate Surveyors and Valuers in the study area. Recommendations were made on how to review the ethical regulations guiding the practice of Estate Surveying and Valuation which will consequently improve marketing in the study area.

    Congenital club foot has been sparsely reported in literature in Nigeria, although it has been reported as the commonest congenital musculoskeletal abnormality. This study enumerates the point prevalence of this disease in a university teaching hospital in Lagos. Better understanding of the epidemiology in our community should improve awareness, and influence management. Between June 2005 and July 2006, 72 consecutive patients with congenital club feet were seen in the orthopaedic clinic of our Hospital. Demographic data, birth weight, family history, birth facility, maternal age and associated congenital anomalies were recorded and analysed using Statistical Programme for Social Sciences (SPSS) version 15. A total of 72 patients were seen, 28 of whom had bilateral club feet resulting in a total of 100 feet. There were 38 males and 34 females. Only 29% presented in the first month of life and 28% in the second month. Maternal ages ranged between 19 and 38 years and no family history of congenital club foot was given,. Babies delivered outside the orthodox medical system (churches, traditional healers, home etc) constituted 28%. The commonest associated congenital anomalies were tibia hemimelia, hydrocephalus, inguinal hernia and umbilical hernia. A default rate of 28% was observed during treatment. Congenital club foot may not be uncommon in Nigeria. Late presentation and high default rate before correction of the deformity were observed. Establishment of special club foot clinics should reduce the default rate. Training of healthcare workers in maternity units as well as Public awareness should encourage early referral to specialists.

    Full Text Available Water from small alluvial aquifers constitutes an attractive and low-cost option for irrigation and rural development in Northeastern Brazil. Based on piezometric measurements, geochemical analyses and electrical conductivity estimates, the present case study identified the main processes determining the hydrosaline dynamics of an alluvial aquifer in a small watershed inserted in the crystalline bedrock of a semi-arid region in Ceará and evaluated the availability of water for irrigation. Accumulation of salts in soil are related to evaporative flux from the aquifer and is increased by irrigation from the groundwater of the alluvial aquifer. The water in these aquifers may be used for irrigation, but represents a risk of soil salinization and alkalinization. Integrated management of surface and underground water resources in the Forquilha watershed may help control irrigation water quality (salinity and residual alkalinity, thereby rationalizing the use of local reservoirs and minimizing losses from evaporation. It has to take into account the complex dynamic of salts and water between the reservoirs, release of water into the river, floods and irrigations.A agricultura irrigada a partir da água subterrânea dos pequenos aqüíferos aluviais é uma alternativa interessante e de baixo custo para o desenvolvimento do meio rural no Nordeste brasileiro.

Al inicio de la década de 1980 se construyó una represa en el río de desagüe y el caudal de salida fue desviado hacia el Embalse Arenal. Se realizó un primer estudio entre 1990 y 1991, y luego en el año 2001 antes de que se construyera una nueva modificación del lago mediante el levantamiento del nivel de la presa en un metro con el fin de utilizar la descarga para la producción de energía hidroeléctrica. Del 2002 al 2010 se realizó un monitoreo limnológico dos veces al año. Aquí se presenta un análisis de las principales características y de los cambios a través del tiempo. El lago es polimíctico discontinuo y desarrolla una termoclina intermitente a 6m de profundidad, la cual puede perdurar por varios días o semanas a juzgar por el desarrollo de una capa anóxica cercana al fondo. Desde su modificación la temperatura superficial del lago ha alcanzado valores mayores a los reportados con anterioridad. El hipolimnion muestra periodos de hipoxia a anoxia que se han vuelto más frecuentes. A pesar de la turbidez del lago, la concentración de nutrientes y de clorofila a son bajos. La tendencia en tiempos recientes es a una reducción de la clorofila a y un aumento en la trasparencia del agua. Estos cambios son similares a los observados en lagos donde se ha logrado atribuirlos al cambio climático global. También se pueden deber a la modificación del flujo del efluente por la operación intermitente de la planta hidroeléctrica, que favorece la acumulación de calor en la columna de agua. Esto debido a que otros factores, como el cambio en el uso del suelo en los alrededores del lago ocurrieron en la década de 1980, por lo que no se les puede atribuir una influencia en los cambios observados en los últimos 10 años.

    The U.S. Geological Survey (USGS) is monitoring and analyzing glacial-lake outburst floods (GLOFs) in the Colonia valley in the Patagonia region of southern Chile. A GLOF is a type of flood that occurs when water impounded by a glacier or a glacial moraine is released catastrophically. In the Colonia valley, GLOFs originating from Lago Cachet Dos, which is dammed by the Colonia Glacier, have recurred periodically since 2008. The water discharged during these GLOFs flows under or through the Colonia Glacier, into Lago Colonia and then the Río Colonia, and finally into the Río Baker—Chile's largest river in terms of volume of water.

    Full Text Available AIM: chemical stratification and the patterns of light limitation and nutrients of two natural lakes, one shallow and the other one deep, were comparatively evaluated, both lakes located in the southeast Brazil. METHODS: pH, electrical conductivity, dissolved oxygen, total dissolved solids and nutrients were monthly collected during 5 consecutive years at the vertical profile of the two lakes. RESULTS: multivariate analysis indicated that the long thermal stratification period favored the occurrence of chemical stratification in the two lakes. However, in the deeper lake the stratified thermal profile with high hypolimnetic nutrient concentration, electrical conductivity, total dissolved solids and redox potential indicated that the mixing was not complete even during the annual circulation period, suggesting a slight meromixis and a high chemical stability at the hypolimnion. In the shallower lake, high light attenuation and high availability of nitrogen forms (mainly N-NH4 and phosphorus was observed along the water column, even during stratification. In the deeper lake, N and P co-limitation and low light attenuation coefficients were detected. CONCLUSION: thermal and chemical stratification patterns indicated that the Carioca lake is a shallow, turbid, nutrient rich, whereas the Dom Helvecio lake is a deep, clear, oligotrophic system with a tendency towards meromixis and the isolation of solutes in the hypolimnion. Consequently, meromixis was compared to a "hypolimnetic memory", which was defined, in the case of the deeper lake, as the maintenance of the chemical stratification along the years, during the lake thermal circulation period.OBJETIVO: a estratificação química e os padrões de limitação por luz e nutrientes foram avaliados comparativamente em dois lagos naturais, sendo um raso e o outro profundo no sudeste do Brasil.

    Full Text Available Background: Fixed drug eruption (FDE is common cutaneous drug eruption characterized by the development of one or more annular, oval, erythematous, and hyperpigmented patches as a result of systemic exposure to a drug. Drugs causing FDE vary with prevailing diseases and prescription pattern in different parts of the world. This study is aimed at reviewing cases of FDE seen at the dermatology outpatient clinic of Lagos University Teaching Hospital (LUTH over a 9-year period, highlighting the spectrum of drugs implicated and the clinical characteristics. Materials and Methods: Data were obtained from the clinic records and patients' case notes. These included the demographic details, duration of presentation, drugs implicated, and clinical characteristics. Results: FDE was diagnosed in 1.8% (295/16,160 of patients seen. There was a slight female preponderance. Antimalarials were the commonest group of medications implicated (51.0% followed by antibiotics (27.9%; analgesics (10.2%, herbal toothpaste (6.1%, and oral hypoglycemic agents (4.1%. Sulfonamides were the commonest group of drugs found in 78 patients (53.1% predominantly as sulfadoxine/pyrimethamine antimalarials and trimethoprim/sulfamethoxazole antibiotics (co-trimoxazole. Conclusion: Concerted efforts are needed to discourage over-the-counter sales and purchase of nonprescription sulfonamide-based medications. A change in prescription pattern from sulfonamides to other classes of antimalarials and antibiotics is desirable and/or recommended. Patients should inform their caregivers at any point of care about their reaction to drugs. It is advised that they have a list of common implicating drugs and they wear a medic alert or carry an ID card bearing this information.

    2011-01-01

    Background Over three-quarter of the world's population is using herbal medicines with an increasing trend globally. Herbal medicines may be beneficial but are not completely harmless. This study aimed to assess the extent of use and the general knowledge of the benefits and safety of herbal medicines among urban residents in Lagos, Nigeria. Methods The study involved 388 participants recruited by cluster and random sampling techniques. Participants were interviewed with a structured open- and close-ended questionnaire. The information obtained comprises the demography and types of herbal medicines used by the respondents; indications for their use; the sources, benefits and adverse effects of the herbal medicines they used. Results A total of 12 herbal medicines (crude or refined) were used by the respondents, either alone or in combination with other herbal medicines. Herbal medicines were reportedly used by 259 (66.8%) respondents. 'Agbo jedi-jedi' (35%) was the most frequently used herbal medicine preparation, followed by 'agbo-iba' (27.5%) and Oroki herbal mixture® (9%). Family and friends had a marked influence on 78.4% of the respondents who used herbal medicine preparations. Herbal medicines were considered safe by half of the respondents despite 20.8% of those who experienced mild to moderate adverse effects. Conclusions Herbal medicine is popular among the respondents but they appear to be ignorant of its potential toxicities. It may be necessary to evaluate the safety, efficacy and quality of herbal medicines and their products through randomised clinical trial studies. Public enlightenment programme about safe use of herbal medicines may be necessary as a means of minimizing the potential adverse effects. PMID:22117933

    Full Text Available Abstract Background Infantile colic is a self-limiting condition that is distributed worldwide. It is often misdiagnosed as an organic disease for which an infant is admitted to the hospital. Many studies have described the aetiopathogenesis, pharmacologic and non-pharmacologic management of colic but none has evaluated self-medication for infants with colic. The aim of this study was therefore to determine the knowledge of Nigerian mothers about colic, their home-based management, extent of self-medication for the infants with colic and the types of medicines involved. Methods It is a prospective study conducted at the vaccination clinics of 20 primary health care centres, each from different Local Government Areas in Lagos, Nigeria. Eight hundred mothers that brought their infants for vaccination between April and September, 2006 were interviewed with open-and close-ended questionnaire. Results Six hundred and eighty three (85.4% mothers claimed they had a good knowledge of colic. Incessant and excessive cry was the main clinical feature of colic identified by 430(62.9% mothers.

    Full Text Available Os painéis reconstituídos à base de madeira ganharam espaço antes ocupado pela madeira maciça, o que tem gerado volume expressivo de resíduos. A indústria moveleira contribui para a geração desses resíduos, que se apresentam como alternativa viável para a exploração de sua aplicação na produção artesanal de pequenos objetos. Este trabalho teve por objetivo produzir pequenos objetos com painéis e com mistura de resíduos de painéis de madeira, a fim de comparar suas qualidades. A partir de 10 projetos gráficos, três artesãos confeccionaram 10 pequenos objetos, utilizando painéis de MDF (Medium Density Fiberboard, OSB (Oriented Strand Board e compensado. Cada artesão produziu nove exemplares de cada objeto. Um quarto artesão confeccionou os mesmos objetos com resíduos de três empresas do polo moveleiro da cidade de Ubá, MG, com três repetições, sendo comparados os atributos de qualidade dos objetos. Concluiu-se que todos os painéis são adequados para a confecção dos objetos e alguns se destacam em relação a outros, conforme o atributo avaliado. Os objetos confeccionados com a mistura de resíduos de painéis de madeira tiveram acabamento uniforme e não apresentaram diferenças significativas em relação aos produzidos com painéis com relação aos atributos funcionalidade, peso, proporção e simetria. A mistura de resíduos de diferentes painéis influenciou negativamente a avaliação dos atributos acabamento, beleza e cor. Um objeto produzido a partir de resíduos do mesmo painel pode ser mais harmonioso e atrativo. É tecnicamente viável a produção de pequenos objetos a partir de resíduos de painéis de madeira vindos de indústrias moveleiras.Wood residue panels have been used in substitution of solid wood. As a consequence, the volume of residues has been increasing day-by-day. The furniture industries are the major generators of these residues. Their use as raw material for the production of

    Full Text Available The aim of this paper was to revise the several homodynamic variables that can be monitored by invasive techniques, direct or indirectly, such as arterial pressure, central venous pressure, cardiac output, systemic vascular resistance, among others. Such techniques offer more accuracy and reliability, and also allow a continuous monitoring, being of great importance and utility in the treatment of the critically ill patient. As they are invasive techniques, they aren’t free of risks and the professional must decide for their utilization analysing the advantages and disadvantages.Com este artigo objetivou-se revisar os diversos parâmetros hemodinâmicos que podem ser monitorados de maneira invasiva, direta ou indiretamente, como a pressão arterial, pressão venosa central, débito cardíaco, resistência vascular periférica, entre outros. Tais técnicas oferecem uma maior confiabilidade e precisão, além de permitirem um monitoramento contínuo, sendo de grande importância e utilidade no tratamento de pacientes em estado crítico. Por serem técnicas invasivas, não são isentas de risco, cabendo ao profissional, face as vantagens e desvantagens inerentes a cada uma, bem como ao estado clínico do paciente, optar ou não pela sua utilização.

    Full Text Available A construção civil é caracterizada como um dos segmentos industriais de maior importância para o desenvolvimento econômico e social do país. Também é conhecida por ser um setor que demanda uma quantidade expressiva de materiais e que desperdiça consideravelmente seus recursos ao longo de toda a sua cadeia produtiva. Por essas razões, o objetivo desta pesquisa foi analisar a incidência de perdas de materiais empregados na etapa de execução do serviço de alvenaria. A pesquisa consiste em um estudo de caso exploratório que teve como área de referência duas obras de empreendimentos residenciais de pequeno porte, localizadas na cidade de Monteiro-PB, onde foi acompanhada a execução da alvenaria de vedação, por ser o serviço de maior representatividade nestas construções. Foram observadas todas as etapas da produção, desde o recebimento do material no canteiro de obras até sua aplicação, a fim de identificar as inconformidades que influenciaram as perdas de materiais na fase de execução do serviço. A partir daí, estas inconformidades foram classificadas segundo sua natureza, momento de incidência e origem e, em seguida, foram mapeadas no processo para serem identificadas como atividades de fluxo ou de conversão. Posteriormente, foi mensurada a incidência de material perdido na fase de produção do serviço, calculando-se o consumo teórico de material previsto para ser usado na construção da alvenaria e o consumo estimado de material despendido para a sua produção. Comparando a quantidade de insumo prevista com a consumida, foi possível estabelecer o índice percentual de material perdido durante o processo produtivo da alvenaria. Como resultado, obteve-se a relação de material perdido e as principais causas que subsidiaram seu desencadeamento. Contudo, é interessante ressaltar a importância do controle dos materiais, cabendo aos gestores buscarem estas melhorias por meio da implementação de mecanismos

    Lagos, a major urban agglomeration in the world is characterized by wetlands and basin for upstream rivers such as Ogun, Oshun and Yewa Rivers. Ongoing environmental pressures exerted by large-scale land reclamation for residential quarters, refuse and sewage dumping, and other uses, however, are suspected to have had a substantial impact on ecological health of the Lagos wetland ecosystems over the last few decades. To determine the impact of these pressures, we examined spatial changes in three wetlands areas- Badore/Langbasa (BL), Festac/Iba/Ijegun (FI) and Ologe/Otto-Awori (OO) through field sample collection and analyses of surface water, sediments, air-water interface gas fluxes and vegetations. Surface water conductivity, total suspended solids (TSS), alkalinity, chloride, biological oxygen demand (BOD), nitrate, phosphate and heavy metals (Zn, Cu, Fe, Na, Mn, Pb, Cd, K and Ni) exhibited relative spatial stability while other water quality parameters varied significantly (P International Union for Conservation of Nature (IUCN). There are indications of steady rise in greenhouse gas levels in Lagos since air CO2 value at BL have reached global threshold of 400 ppm with OO and FI closely approaching. We conclude that the Lagos wetland ecosystems, especially OO and FI still have some semblance of natural habitat. However, further destruction and unwise use of the resources could cause damage to physical, chemical, geological and biological processes in nature, which could result to grave socio-economic and cultural consequences to the local communities whose livelihood and lifestyle depend on these valued wetlands.

    To investigate the prevalence of maternal selenium deficiency and its effects on pregnancy outcomes in pregnant women with HIV in Lagos, Nigeria. The present descriptive cross-sectional study enrolled women aged 15-49 years with HIV who were at 14-26 weeks of a singleton pregnancy and were attending Lagos University Teaching Hospital, Lagos, Nigeria, between August 1, 2016, and April 30, 2017. Participants were selected by consecutive sampling and baseline data were collected through interviews. Venous blood samples were obtained to measure selenium concentrations, and associations between low maternal selenium concentrations (defined as <0.89 μmol/L) and pregnancy outcomes were examined using bivariate and multivariate analysis. The final analysis included 113 patients; selenium deficiency was recorded in 23 (20.4%) patients. Women with selenium deficiency had an approximately eight-fold higher risk of preterm delivery (adjusted odds ratio 7.61, 95% confidence interval 4.37-18.89; P=0.031) and of delivering a term neonate with a low delivery weight (adjusted odds ratio 8.11, 95% confidence interval 3.27-17.22; P=0.012), compared with women with a normal selenium concentration. The prevalence of selenium deficiency among pregnant women with HIV in Lagos was relatively high. The significant associations observed between maternal selenium deficiency and adverse pregnancy outcomes could have implications for the future management of HIV in pregnancy. © 2018 International Federation of Gynecology and Obstetrics.

  16. Within salvation: girl hawkers and the colonial state in development era Lagos.

    Science.gov (United States)

    George, Abosede

    2011-01-01

    For almost two decades between the close of the Second World War and Nigerian independence in 1960, the British colonial state which faced a crisis of legitimacy in Lagos upheld city ordinances that made itinerant trading by young children in Lagos a punishable status offense. Although anti-trading regulations were gender-neutral in their language, girls were disproportionately sanctioned for engaging in street trading and related activities. In defending their concentration on girl sellers over boy sellers, colonial welfare officials painted a picture of the urban context as an inherently dangerous context and of girls as being particularly at risk of violent assault in the city, making them particularly in need of protection from town life. Sources which show that parents generally resisted or ignored the street trading regulations and continued permitting their daughters to sell despite entreaties, warnings, or fines from colonial officials, suggest that African parents and British colonial officials may have had conflicting views on the inherent danger of the city, on what constituted child endangerment, and on the gendered nature of childhood. This article argues that the girl saving campaigns of development era Lagos were as much about the legitimization of a colonial state facing a crisis of legitimacy as they were about debates between African parents and colonial welfare officials in Lagos concerning ideas of children and childhood and the dangers of street trading by African girls.

    Full Text Available The clinicopathological and endoscopic features of dyspepsia have not been well studied in Nigeria due to the high cost of gastroscopes and lack of the relevant expertise. This study was designed to highlight these features and possible risk factors. This prospective study was conducted on adult dyspeptic patients who fulfilled the study criteria from November 2007 to December 2008 at a University hospital in Lagos, Nigeria. Demographic and clinical presentation including possible risk factors were obtained through a questionnaire administered by an interviewer followed by an upper gastrointestinal endoscopy and gastric biopsy. Of the 123 subjects who took part in the study, 100 gave their consent to an upper gastrointestinal endoscopy and biopsy. The male:female ratio was 1:1, mean age was 44.98 (SD 15.4 years and the modal age group was 38-47years. The prevalence of dyspepsia was 29% and epigastric pain was the most common presentation. Endoscopic findings were superficial mucosal lesion (21%, peptic ulcer (16%, features of gastroesophageal reflux disease (10%, and gastric cancer (2%, as well normal findings (44%. Non-steroidal antiinflammatory drug (NSAID use as a risk factor had a significant association with positive endoscopic findings; relative risk for development of positive endoscopic findings was 1.5% (P =0.03. Histology showed rates of chronic gastritis to be 91% and normal values 9%. The most common type of gastritis was the non-specific form (59.3%, followed by H. Pylori-associated gastritis (36.3%. The topography of gastritis was mainly pangastritis (68.1% and antral predominant in 23.1%. The prevalence of H. pylori by histology was 41%. The presence of H. pylori was not associated with severity, location or duration of symptoms. H. pylori was, however, found to be a significant contributor to the development of positive endoscopic findings (P=0.01; OR 2.92 95% CI 1.50-3.17.

    2016-01-01

    The upsurge in the reported cases of diverticular disease (DD) has led to a re-appraisal of the earlier held views that it was a rare entity in Nigeria. The advent of colonoscopy has contributed in no small way to this change. We sought to determine the clinical characteristics, indications for colonoscopy, and intra-procedural findings among these patients. A retrospective cross-sectional study was carried out on the colonoscopy records from four private endoscopy units based in Lagos State, Nigeria. The records were drawn from a 5-year period (August 2010 to July 2015). The endoscopy logs and reports were reviewed, and the bio data, indications, and colonoscopy findings were gleaned. A total of 265 colonoscopies were carried out in the stated period. Of these, 28 (10.6%) had DD. Of the patients with DD, 5 (17.9%) were females while 23 (82.1%) were males. Their ages ranged from 46 to 94 years (mean = 68.2 ± 11 years). Fifteen patients had been referred for the procedure on account of hematochezia alone (15 = 53.6%). Other reasons for referral included abdominal pain alone (2 = 7%), hematochezia plus abdominal pain (5 = 17.9%), and change in bowel habits (3 = 10.8%). Ten (35%) patients had pan-colonic involvement. Regional disease involved the right side alone in only one case (3.5%) while the other combinations of sites are as follows; 6 (21.4%) in the sigmoid colon alone, 2 (7%) in the descending colon alone, 5 (17.9%) in the sigmoid-descending colon, 4 (14.3%) in the sigmoid-descending-transverse colon, thus the sigmoid colon was involved in 25 (89.3%) cases. Five cases (17.9%) had endoscopic features suggestive of diverticulitis. DD should no longer be regarded as a rare problem in the Nigerian patient. The study findings support the notion of higher prevalence among the elderly, in males, and of sigmoid colon involvement.

    2016-01-01

    Full Text Available Background and Objective: According to the World Health Organization, the number of obese children would increase to 70 million by 2025 if no intervention is made. An increase in the prevalence of overweight and obesity among school children in Lagos State, Nigeria has been established, but specific factors promoting its prevalence are unknown. The aim of this study was to elicit the views of stakeholders on the perceived causes for the rise in child overweight and obesity. Methods: Five focus group discussions were conducted with different groups of stakeholders involved in child care, namely: Parents, teachers, and healthcare givers. Participants were recruited using a purposive sampling method; a structured question guide was employed for the discussion sessions. The discussions were recorded, collated, and analyzed using grounded theory to extract themes. Results: Six themes emerged as factors responsible for the rise, of which civilization and lifestyle imbalance of the populace emerged as the prominent cause. Of the fifty respondents, 76% of respondents identified parents (particularly young mothers as major contributors to the prevalence of overweight and obesity in children of Lagos State; and 52.3% of the participants reported that a direct relationship exists between income class of parent and weight of a child resident in Lagos. Conclusion: Civilization and lifestyle imbalance, insecurity and congestion, low level of public awareness, inadequate educative and enlightenment programs, myths and societal perception were factors identified to responsible for the rise in the prevalence of child obesity in Lagos, Nigeria. Preventive strategies to control the prevalence of overweight and obesity in children residing in Lagos State should be considered for further studies.

The state government embarked on series of what it calls sustainable urban transformation policies towards making Lagos ‘an African model megacity’ and a global economic and financial hub that is safe, secure, functional and productive, with a view to achieving poverty alleviation and sustainable development. This paper, through the lens of theoretical and analytical underpinnings of Sustainable Livelihoods Framework, however, argues that the actions of the state government contradict the whole essence of sustainable urban development and poverty alleviation, but reflect an agenda deliberately targeted to further impoverish the poor. While the Sustainable Livelihood was used as the theoretical and analytical framework, this paper essentially focuses on the Policies, Institutions and Processes component of the framework. This provides a unique entry point for understanding the implications of the Lagos urban development aspirations on the livelihoods of the urban poor. The research uses mixed methods research design with a broad range of data-collection methods, including household surveys, interviews, direct observation and photography, documentary review and policy document analysis. The study reveals that there is a disconnection between urban development policies and realities of the poor. The implementation of urban development projects and policies works against the urban poor and resulted in more hardship, through reduction in livelihood opportunities or complete loss of livelihoods. This study, therefore, suggests that one important element in reducing poverty in Lagos’ informal settlements is a policy

    Reconciling orbital-scale patterns of inter-hemispheric South American climate during the Quaternary requires continuous, high-resolution paleoclimate records that span multiple glacial cycles from both hemispheres. Southern Andean Quaternary climates are represented by multi-proxy results from Lake Titicaca (Peru-Bolivia) spanning the last 400 ka and by pending results from the Lago Junin Drilling Project (Peru). Although Northern Andean sediment records spanning the last few million years have been retrieved from the Bogota and Fúquene Basins in the Eastern Cordillera of the Colombian Andes, climatic reconstructions based on these cores have thus far been limited to pollen-based investigations. When viewed together with the Southern Hemisphere results, these records suggest an anti-phased hemispheric climatic response during glacial cycles. In order to better assess orbital-scale climate responses, however, independent temperature and hydroclimate proxies from the Northern Hemisphere are needed in addition to vegetation histories. As part of this objective, an effort is underway to develop a paleoclimate record from Lago de Tota (3030 m asl), the largest lake in Colombia and the third largest lake in the Andes. One of 17 highland tectonic basins in Eastern Cordillera, Lago de Tota formed during Tertiary uplift that deformed pre-foreland megasequences, synrift and back-arc megasequences. The precise age and thickness of sediments in the Lago de Tota basin has not previously been established. Here, we present results from a recent single-channel seismic reflection survey collected with a small (5 cubic inch) air gun and high-resolution CHIRP sub-bottom data. With these data, we examine the depositional history and sequence stratigraphy of Lago de Tota and assess its potential as a deep drilling target.

    Lago Cerrillos dam, located in the municipality of Ponce in southern Puerto Rico, was constructed in 1991 as part of the multipurpose Rio Portugues and Bucana Project. This project provides flood protection, water supply, and recreation facilities for the municipio of Ponce. The reservoir had an original storage capacity of 38.03 million cubic meters at maximum conservation pool elevation of 174.65 meters above mean sea level and a drainage area of 45.32 square kilometers. Sedimentation in Lago Cerrillos reservoir has reduced the storage capacity from 38.03 million cubic meters in 1991 to 37.26 million cubic meters in 2008, which represents a total storage loss of about 2 percent. During July 29 to August 23, 2002, 8,492 cubic meters of sediment were removed from the Rio Cerrillos mouth of the reservoir. Taking into account this removed material, the total water-storage loss as of 2008 is 778,492 cubic meters, and the long-term annual water-storage capacity loss rate is about 45,794 cubic meters per year or about 0.12 percent per year. The Lago Cerrillos net sediment-contributing drainage area has an average sediment yield of about 1,069 cubic meters per square kilometer per year. Sediment accumulation in Lago Cerrillos is not uniformly distributed and averages about 3 meters in thickness. This represents a sediment deposition rate of about 18 centimeters per year. On the basis of the 2008 reservoir storage capacity of 37.26 million cubic meters per year and a long-term sedimentation rate of 45,794 cubic meters per year, Lago Cerrillos is estimated to have a useful life of about 814 years or until the year 2822.

HPV is preventable with the use of HPV vaccines. Objectives: The objective of this study was to assess mothers' HPV knowledge and their willingness to vaccinate their adolescent daughters in Lagos, Nigeria. Materials and methods: This study was a community-based, descriptive cross-sectional study carried out in July, 2012 in Shomolu Local Government Area (LGA of Lagos State, Nigeria. Multistage sampling method was employed to select the 290 respondents who participated in the study. Structured, pretested, interviewer-administered questionnaires were used for data collection. Data was analyzed with Epi-Info™ version 7. Results: The study revealed low awareness of HPV (27.9% and HPV vaccines (19.7% among the mothers that participated. There was a high awareness for cervical cancer but little knowledge of its link to HPV. Awareness and utilization of HPV vaccines increased with increasing educational level (P<0.05. There was a high willingness and intention among the mothers to vaccinate their girls (88.9% and to recommend the vaccine to others (91.0%. Accessibility and affordability of the HPV vaccines were found to be possible barriers to future utilization of the vaccines. Conclusion: Despite low knowledge about HPV and HPV vaccines, mothers were willing to vaccinate their daughters. We recommend improving mothers' knowledge by education and the possible inclusion of the vaccine in the national immunization

    Full Text Available The study examined effects of manpower planning and development in Lagos state civil service performance. Lagos state civil service is the greatest asset of the state in its quest for socio-economic development. The primary question that was explored is whether the nature of manpower planning and development curriculum in Lagos state civil service has effect on the service performance and the attainment of state objective. The study relied on primary and secondary data, and multiple stage sampling technique was used to select the sample population. The data collected was presented in frequency bar chart and simple percentage. Pearson’s Product Moment Correlation Coefficient (PPMC statistical tool was used to test the hypotheses. Findings of the study show that the nature of manpower planning and development curriculum has a positive effect on the Lagos state civil performance. It also reveals that the manpower planning and development has a positive effect on the attainment of Lagos state objective. To achieve better performance in the service, it should among others, improve on the current manpower planning strategy and continue to update its manpower development curriculum in line with the global best practices. Given the pivotal role that technology plays in the 21st century, the service should avail itself the windows of opportunities that information technology provides in its drive to enhance employees’ skills, knowledge and abilities that will invariably improve the service performance. Yet, the service should imbibe the prescripts of New PublicManagement theory (NPM, and that goals and targets should be defined and measurable as indicators of organizational performance.

    Full Text Available Dados do SEBRAE (2014 destacam que as micro e pequenas empresas – MPEs respondem por cerca de 91% dos empregos e 27% do Produto Interno Bruto. No entanto, apesar da importância das MPEs, nota-se um interesse ainda pequeno no sentido de conhecer, analisar e propor alternativas para esse segmento empresarial. O presente estudo objetiva verificar se os gestores das MPEs recebem, compreendem e utilizam informações contábeis em seu processo de gestão. Três construtos foram investigados, (1 compreensão da informação; (2 utilização da informação e (3 recebimento da informação e relacionamento entre gestor e contador. A amostra foi constituída por 50 empresas da região centro-oeste do Estado do Paraná. A coleta de dados foi realizada pessoalmente, por meio de questionário com questões abertas e fechadas com escala Likert. Os resultados mostram que os gestores recebem parte das informações, não as compreendem, porém as usam como subsídio em seu processo decisório, dentro do limite de sua compreensão. Ainda se observou que o nível de formação do gestor interfere na compreensibilidade da informação. Com α < 0,01 foi demonstrado que o grau de instrução do gestor é determinante na compreensão da informação, já que existe diferença entre o escore médio de cada grupo.

    The U.S. Geological Survey, in cooperation with the Puerto Rico Electric Power Authority, completed hydrologic and hydraulic analyses to assess the potential hazard to human life and property associated with the hypothetical failure of the Lago El Guineo Dam. The Lago El Guineo Dam is within the headwaters of the Río Grande de Manatí and impounds a drainage area of about 4.25 square kilometers.The hydrologic assessment was designed to determine the outflow hydrographs and peak discharges for Lago El Guineo and other subbasins in the Río Grande de Manatí hydrographic basin for three extreme rainfall events: (1) a 6-hour probable maximum precipitation event, (2) a 24-hour probable maximum precipitation event, and (3) a 24-hour, 100-year recurrence rainfall event. The hydraulic study simulated a dam failure of Lago El Guineo Dam using flood hydrographs generated from the hydrologic study. The simulated dam failure generated a hydrograph that was routed downstream from Lago El Guineo Dam through the lower reaches of the Río Toro Negro and the Río Grande de Manatí to determine water-surface profiles developed from the event-based hydrologic scenarios and “sunny day” conditions. The Hydrologic Engineering Center’s Hydrologic Modeling System (HEC–HMS) and Hydrologic Engineering Center’s River Analysis System (HEC–RAS) computer programs, developed by the U.S. Army Corps of Engineers, were used for the hydrologic and hydraulic modeling, respectively. The flow routing in the hydraulic analyses was completed using the unsteady flow module available in the HEC–RAS model.Above the Lago El Guineo Dam, the simulated inflow peak discharges from HEC–HMS resulted in about 550 and 414 cubic meters per second for the 6- and 24-hour probable maximum precipitation events, respectively. The 24-hour, 100-year recurrence storm simulation resulted in a peak discharge of about 216 cubic meters per second. For the hydrologic analysis, no dam failure conditions are

    Full Text Available Ao longo da história médica a definição e a forma de se definir o diagnóstico do Transtorno do Déficit de Atenção e Hiperatividade (TDAH culminaram em uma medicalização excessiva e questionável de crianças participantes do cenário educacional. Essa medicalização da vida no ambiente escolar se realiza aliada a um processo histórico e social de normatização imposto pela biopolítica, e, consequentemente, um aumento de diagnósticos visando melhorar o desempenho do aluno. Christoph Türcke ao falar sobre os choques imagéticos auxilia na compreensão do TDAH. Para ele, o choque de imagens apresentadas pelos aparatos audiovisuais exerce uma fascinação estética que, ao fornecer sempre novas imagens, estabelece um espaço mental, em regime de atenção excessiva. Novos padrões de socialização, dessa forma, vão se sedimentando no que se pode denominar de uma mutação subjetiva ligada às imagens e, por conseguinte, medicalizada. Enfim, o TDAH encontra-se nesse espaço em que a criança que possui o déficit de atenção é a criança da cultura atual, denominada por cultura High-tech, em que os sintomas do TDAH são da sociedade contemporânea.

This study utilized 2,500 households’ samples in Lagos metropolis. The questionnaire about intra-city trip patterns was administered in direct proportion to the population size of each Local Government Areas (LGAs. Systematic sampling technique was used to select every tenth building on the identified streets. lt is observed that more than 95% of residents depends on roads, while less than 5% depends on Rail and Ferry. Work and business trips characterized the weekdays, while social, shopping and recreation trips dominate the weekends. This situation leads to too many vehicular traffic on the roads during the peak periods, leading to congestion and loss of valuable man-hours. Transportation planners in Lagos need to develop alternative intra-city transportation systems.

    Full Text Available Background: Child adoption is a recommended alternative form of infertility management. Infertility is of public health importance in Nigeria and many other developing nations. This is a result of its high prevalence and especially because of its serious social implications as the African society places a passionate premium on procreation in any family setting. Objectives: The aim of this study was to determine the knowledge, attitude and practice of child adoption amongst women attending infertility clinics in teaching hospitals in Lagos State and to determine the factors that influence their attitude and practice towards it. Method: A cross-sectional descriptive design was used. Data were collected by using a structured questionnaire which was interviewer-administered. The study was conducted in the two teaching hospitals in Lagos State (LUTH [Lagos University Teaching Hospital] and LASUTH [Lagos State University Teaching Hospital] from amongst 350 women attending the gynaecological clinics. All the patients under management for infertility at the gynaecology clinics during the period of the study were interviewed. Results: Many respondents (85.7% had heard of child adoption and 59.3% of them knew the correct meaning of the term. More than half of the respondents (68.3% said that they could love an adopted child but less than half of them (33.7% were willing to consider adoption. Only 13.9% has ever adopted a child. The major reason given for their unwillingness to adopt was their desire to have their own biological child. Factors that were favourable towards child adoption were Igbo tribe identity, an age above 40 years, duration of infertility above 15 years, and knowing the correct meaning of child adoption. Conclusion: There is a poor attitude to adoption even amongst infertile couples. Interventions need to be implemented to educate the public on child adoption, to improve their attitude towards adoption and to make it more acceptable.

  12. Murciélagos hematófagos como reservorios de la rabia

    Karin Corrêa Scheffer

    Full Text Available La rabia continua siendo un desafío para las autoridades de salud pública y una limitante para la industria ganadera en América Latina. Caninos silvestres y domésticos, así como murciélagos hematófagos son las principales especies transmisoras y reservorios de la enfermedad. Actualmente, se observa variaciones en el perfil epidemiológico de la rabia, donde la especie de murciélago hematófago Desmodus rotundus se constituye en la principal especie transmisora. A lo largo del tiempo se ha acumulado conocimiento sobre la ecología, biología y comportamiento de esta especie y sobre la historia natural de la rabia, lo cual debe conducir a una continua evolución de los métodos de control poblacional de D. rotundus, prevención y técnicas de diagnóstico. Aún se desconoce la relación ecológica de esta especie con otras hematófagas y no hematófagas, y queda mucho por mejorar en los sistemas de notificación y vigilancia epidemiológica, así como crear una mayor conciencia entre los ganaderos ante el tema. La comprensión del impacto que las modificaciones ambientales inducidas por el hombre ejercen sobre la dinámica de infección del virus de la rabia en los murciélagos debe ser motivo de investigaciones posteriores. Esto requerirá la combinación de estudios de campo con modelos matemáticos y nuevas herramientas diagnósticas. La presente revisión pretende presentar los aspectos más relevantes sobre el rol de los murciélagos hematófagos como reservorios y transmisores del virus de la rabia

    Full Text Available An alternative method for identifying and inventorying rodents and marsupials inhabiting forests and grasslands of Brazilian Cerrado is presented and discussed. Ink tracking tunnels were designed according to the size of target species and used to build a reference collection of small mammal footprints composed of 1408 footprints belonging to 251 individuals from 30 species (21 rodents and nine marsupials. Sherman traps and ink tracking tunnels were used to conduct inventories in gallery forests. Footprints obtained in ink tracking tunnels were digitalized and compared with those in reference collection using Discriminant Analysis (DFA. DFA allowed good footprint differentiation, even among congeneric species. In DFA analysis, the first two axis were related to size and arboreality. The efficiency of ink tracking tunnels was higher (track-success = 31% than conventional trapping (trap-success = 14% in inventories. Ink tracking tunnels gave a good description of the small mammal community of gallery forest by detecting rodents and marsupials of different habits, including trap-shy species. This paper also discusses advantages and limitations of ink tracking tunnels use in inventories and ecological studies, and concludes that this technique can be efficient in long-term studies and in rapid inventories as a complementary technique for trapping.Um método alternativo de identificação e inventário de roedores e marsupiais de florestas e áreas abertas do Cerrado é apresentado e discutido.

    LAGO is an extended cosmic ray observatory composed of water-Cherenkov detectors (WCD) placed throughout Latin America. It is dedicated to the study of various issues related to astrophysics, space weather and atmospheric physics at the regional scale. In this paper we present the design and implementation of the front-end electronics and the data acquisition system for readout of the WCDs of LAGO. The system consists of preamplifiers and a digital board sending data to a computer via an USB interface. The analog signals are acquired from three independent channels at a maximum rate of ~1.2×105 pulses per second and a sampling rate of 40 MHz. To avoid false trigger due to baseline fluctuations, we present in this work a baseline correction algorithm that makes it possible to use WCDs to study variations of the environmental radiation. A data logging software has been designed to format the received data. It also enables an easy access to the data for an off-line analysis, together with the operational conditions and environmental information. The system is currently used at different sites of LAGO.

    Full Text Available This study examined the relationship between waste management logistics and identified metrics for waste management logistics performance. Secondly, the study assessed the various challenges inhibiting the performance of LAWMA in the State. Random table sampling and purposive sampling were used to select 47 waste collection centres with 10 questionnaires distributed per centre (470 in total across the 20 Local Government Areas (LGA in Lagos State. However, only 339 questionnaires were retrieved from the sampled population. Multiple regression analysis was used to predict the relationship between waste management logistics and identified metrics for waste logistics performance. Descriptive statistics was used to explain the challenges of the Lagos State Waste Management Authority (LAWMA. The results established that the volume of solid waste and commitment of staff are crucial to waste management logistics and one factor that strongly affects waste logistics is traffic in the metropolis. Conclusively, waste collection turnaround must be increased and government and private investors should provide enabling infrastructure and trained personnel for effective solid waste management in Lagos metropolis.

    Full Text Available Nigeria as a developing nation is facing increasing demand for electricity especially in the residential areas. The use of compact fluorescent lamps (CFLs is one of the several measures towards reducing the demand. However, in Nigeria, the use of CFLs is low. The present study was designed to investigate some factors responsible for the low usage of CFLs in Lagos, Nigeria. Questionnaires were administered by hand on 984 households, selected through systematic random sampling techniques from 5 local government areas in Lagos State. The first building along the major street in each of the local government was selected randomly and every tenth building constituted the sample. A household head was surveyed in each of the building selected, and was asked to rate some factors that might have influenced the usage of CFLs. The data generated from the questionnaire were analysed using ranking method. The findings show that inability to measure the saving benefits of CFLs on electricity bills, lack of affordability and high initial cost of acquisition and installation were the most important factors which influence the use of the CFLs. The study concludes by providing some recommendations on how to achieve sustainable energy management in the Lagos and beyond through more efficient residential house lighting.

    Full Text Available Transformation means positive change to new values and direction. This research is concerned with the relationship between empowerment processes that are transformatory and gender equality in the workplace. Its scope includes integrating a transformatory view into women’s and men’s consciousness and autonomy over their career, education and health. This research adopted a case-study approach by using the Ministries of Education, Health, Establishment, Training and Pensions and the Civil Service Commission in Lagos State, employing a combination of qualitative and quantitative research methods as its empirical research methodology. The field work was carried out in Lagos State in the months of June and July, 2014 while the interview was in July and August, 2014. This study demonstrated that gender-blind policies disempower women and perpetuate gender inequalities in the Lagos State Civil Service. Further, it shows that the manifestation of transformatory empowerment is jeopardised by women and men's compliance with the existing expectations and inaction to bring about changes in policies and practices that are detrimental to the attainment of gender equality in the work place.

    Proper management and safe disposal of medical waste (MW) is vital in the reduction of infection or illness through contact with discarded material and in the prevention of environmental contamination in hospital facilities. The management practices for MW in selected healthcare facilities in Lagos, Nigeria were assessed. The cross-sectional study involved the use of questionnaires, in-depth interviews, focused group discussions and participant observation strategies. It also involved the collection, segregation, identification and weighing of waste types from wards and units in the representative facilities in Lagos, Nigeria, for qualitative and quantitative analysis of the MW streams. The findings indicated that the selected Nigerian healthcare facilities were lacking in the adoption of sound MW management (MWM) practices. The average MW ranged from 0.01 kg/bed/day to 3.98 kg/bed/day. Moreover, about 30% of the domestic waste from the healthcare facilities consisted of MW due to inappropriate co-disposal practices. Multiple linear regression was applied to predict the volume of waste generated giving a correlation coefficient (R(2)) value of 0.99 confirming a good fit of the data. This study revealed that the current MWM practices and strategies in Lagos are weak, and suggests an urgent need for review to achieve vital reversals in the current trends.

    Full Text Available Road transport is one of the most common means of transportation across the world. Bus transportation in Nigeria had witnessed many problems for the past decades considering the growing population with the attendant loss of lives and properties in most cities like Lagos in Nigeria. This paper focuses on the adequacy of services provided by Bus Rapid Transit (BRT in Lagos State with respect to the extent to which it influences the socioeconomic conditions of bus commuters. It examines the effect of services rendered by BRT on cost reduction potential, income and safety. Multistage sampling technique was used to select 20 samples each from all respondents in all local government area in Lagos State to reach a total of three hundred and thirty (330 samples. The data collection instrument was the questionnaire which was validated. Data collected were analysed with the use of descriptive statistics such as means, percentages and standard deviation and inferential statistics such as regression and analysis of variance techniques. Findings showed that BRT services has reduced the cost of bus commuters and also increased safety and security thereby increasing the socioeconomic condition of Lagosians. The study recommends improvements in BRT services through the deployment of technology as it had been used in developed countries.

    Full Text Available A survey of medical waste management (MWM practices and their implications to health and environment was carried out in metropolitan Lagos. Lagos is currently the most populous and urbanized city in the country with an estimated population of over 13 million people. The study assessed management practices in four (2 privates and 2 publics hospitals ranging in capacity from 40 to 600 beds. Empirical data was obtained on medical waste generation, segregation, storage, collection, transportation and disposal. The observed MWM practices in all hospitals indicate absence of full compliance with the protocol for handling medical waste as stipulated in the relevant sections of the guidelines and standards for environmental pollution control in Nigeria. Three hospitals demonstrated high priority for segregation of infectious medical waste. Average generation rate of medical waste in the investigated hospitals ranged from 0.562 kg/bed.day to 0.670 kg/bed.day. Infectious waste accounts for between 26 to 37% of this volume. Only two of the hospitals investigated carry out treatment of their infectious and sharp waste types by incineration before final disposal. Burning and burial of medical waste is an unusual but common practice among the hospitals. All the hospitals employ the services of the state owned solid waste management company, the Lagos State Waste Management Authority (LAWMA for final collection, and disposal of their medical waste at government approved sites.

Visto ser de fundamental importância na cirurgia ortopédica de pequenos animais, o trabalho teve por objetivo discorrer sobre a função, locais de colheita, cuidados, formas de aplicação, indicações e contra-indicações desse enxerto. Ele estimula a formação óssea devido ao fornecimento de células vivas e fatores de crescimento, mas não possui suporte mecânico. A asa do ílio craniodorsal, úmero proximal, tíbia proximal e fêmur distal, são os locais de colheita mais utilizados em cães. A asa do ílio consiste no local mais satisfatório para gatos. Para maximizar a incorporação do enxerto com o tecido hospedeiro, devem ser tomados alguns cuidados entre a colheita e a transferência para a área receptora. Além disso, pode ser aplicado sem compressão dentro do local recipiente. A freqüência de complicações é considerada baixa.The autologous cancellous bone is formed by trabecular bone, porous, and highly cellular. Since this graft is very important in orthopedic surgery of small animals, the purpose of this paper is to describe the function, donor sites, precautions, application methods, indications, and contraindications. It stimulates the bone formation because it provides live cells and growth factors, but it did not have mechanical support. Cranial dorsal wing of the ilium, proximal humerus, proximal tibia, and distal femur are the most common harvest sites used in dogs. The wing of the ilium is the most satisfactory harvest site in cats. To maximize the graft incorporation with the tissue it is necessary to take care during the harvest and transference to recipient site. In addition, it may be put into the recipient site with no compression. The frequency of complications is considered low.

    Full Text Available “Lago de Guadalupe” is an important freshwater ecosystem located in the northern part of the metropolitan area surrounding Mexico City, under high demographic pressure. It receives approximately 15 hm3·y-1 of untreated municipal wastewater from the surrounding municipalities. In order to develop a comparative assessment of the pollution effect over the limnological characteristics of Lago de Guadalupe, this lake was characterised from February 2006 to July 2009, and the results were compared with those obtained from a non-polluted lake “Lago el Llano” located in the same drainage area. Lago de Guadalupe was hypereutrophic with anoxic conditions throughout most of the water column. In contrast, Lago el Llano was mesotrophic with high dissolved oxygen concentrations throughout the entire water column with a clinograde profile. Both reservoirs had a monomictic mixing regime. The longitudinal zonation of physicochemical and biological variables were investigated in order to better understand the processes controlling the water quality across the reservoir during its residence time. This study shows the impact of anthropogenic pollution on the limnological characteristics of a subtropical reservoir and confirms that under adequate management schemes, namely avoiding pollution and wastewater discharges, subtropical reservoirs can be prevented from developing eutrophic conditions.

    Martignano lake is a particular charming volcanic lake in the countryside of Rome. Recently it was included in a project of Regional Wildlife Park. The lack of immissaries and emissaries, the quite long renewal time and the very short homeothermic period of two-months in a year, make the lake susceptible of trophic evolution. The comparison between the present data and those from previous studies seems to confirm such a slow development towards this way, with a nutrient level (nitrate 0.97 mg/L; total phosphorus 11.14 {mu}g/L) and chlorophyll a concentrations (10.68 {mu}g/L), typical of mesotrophic waters. The analysis of nutrient data expressed as annual mean value in percentage from the coastal stations, suggests an under lied farming influence, and points out the need to adopt fast reduction measures, to lower the phosphorus load in acceptable levels for the lake ecosystem. [Italian] Il lago di Martignano (207 m.s.l.m) e' situato nell'Italia centrale, a 35 Km a nord di Roma. I laghi di origine vulcanica rappresentano una tipologia relativamente rara rispetto all'insieme dei corpi d'acqua componenti la limnologia classica. La loro esistenza si determina in regioni con passata o attuale pronunciata attivita' tettonica. La mancanza di immissari ed emissari che caratterizza questo invaso rende particolarmente vulnerabile il suo livello trofico da parte delle contaminazioni da insediamenti urbani ed agricoli circostanti. Ai fini di valutare l'attuale velocita' di ricambio idrico del lago, il suo livello trofico e la conseguente capacita' di automantenimento di un basso livello trofico delle acque, e' stato pianificato il presente studio articolato in 13 mesi di campionamento. Si e' constatato che il valore medio annuale della clorofilla a, 10.68 {mu}g/L, mentre la presenza dei nitrati si aggira sul valore medio di 0.97 mg/L, cio' permette di ipotizzare l'origine agricola della maggior parte dei nutrienti del

    The accident and emergency department constitutes one of the vital entry points of patients into the healthcare facility of the hospital the world over. It responds to and manages variety of cases in all the clinical areas and thus pr vides an insight to the quality of care available in the health institution. The aim of this study is to determine the pattern of cases seen as well as the causes of deaths at the adult accident and emergency department of the Lagos UniversityTeaching Hospital, Idi-Araba, Lagos. Retrospective review of records of all patients attended to at the adult accident and emergency department of the Lagos University Teaching Hospital in 2009 and 2010 was carried out. Data spread sheet was used to collect data on demographic indices, diagnosis, outcome, date admitted, date discharged and amount paid from casualty attendance register and Nurses' report books. Data was collated and analysed using Epi-Info version 3.4.1 statistical software package. Out of the 5,427 available patients' records reviewed, 4,761(87.7%) were recorded as "discharged alive", 546 (10.1%) were recorded as "died", while 120 (2.2%) were recorded as "brought in dead". Of those discharged alive, male attendance was 2,376 (49.10%) while that of the female was 2,385 (50.10%). Majority of these patients were aged 20-39 years and the mean age of the patients was 39.96 +/- 18.22 yrs. Majority of cases seen were medical in origin (53.7%) and highest medical case seen was cerebrovascular accident, Commonest cause of death was from medical cases [69.2%] (cerebrovascular accident 22.0%). Male mortality was 55.3% while female mortality was 44.7%, mean age was 46.86 +/- 17.61. Most affected age group was 40 - 59 years (35.4%) and highest number of death was seen in December. The commonest case seen as well as commonest cause of death was cerebrovascular accident. A high number of heart failure, head injuries, road traffic accidents, upper gastrointestinal bleeding and post partum

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

Assim, este estudo teve por objetivo avaliar as características morfométricas da sub-bacia do Córrego da Cascata, em Botucatu (SP, e suas implicações no processo de assoreamento de um lago integrante dessa sub-bacia. A avaliação contou com índices gerados a partir de dados calculados com base cartográfica digitalizada e georreferenciada na escala 1:10.000, com utilização do AutoCAD Map 2004. Foi também utilizado o software Quantum GIS 1.8, para gerar o modelo digital de elevação (MDE e o mapa de declividades que permitiu obter a declividade média (Dm da sub-bacia. Através dos índices fator de forma (Kf, sinuosidade (Is, circularidade (Ic e coeficiente de compacidade (Kc, a sub-bacia do Córrego da Cascata apresentou forma alongada, com baixa propensão a enchentes e com escoamento rápido. Os índices densidade de drenagem (Dd e relação de relevo (Rr indicaram drenagem média e mais eficiente, o que favorece a elevada dissecação e o médio estágio erosivo. O índice coeficiente de rugosidade (Cr indicou que se trata de uma sub-bacia vocacionada à agricultura. A intervenção antrópica na linha do divisor de águas observada in loco é o principal fator do carreamento de sedimentos no lago e não apenas compromete a beleza paisagística do local como altera a vida aquática do ecossistema.

    Full Text Available The paper reports a study carried out on the utilisation of the Internet by agricultural science teachers in Lagos state focusing on uses, practices, and barriers. A questionnaire was developed based on literature and was administered to 300 agricultural science teachers in Lagos schools. 275 questionnaires properly completed were analyzed. Data reveal that 130 teachers are using the Internet for teaching agricultural science in classrooms as well as for various activities that enhance their professional development. Nevertheless, it was found that agricultural science teachers in Lagos State have not fully utilised the Internet because of barriers related to time factor, accessibility, and facilities. It is suggested that for the proliferation of Internet practices, there needs to be an increase in funding for technology, an introduction of computer/technology education, a provision of pedagogical training for teachers, and a provision of administrational support.

Os corpos de prova soldados com diferentes níveis de energia, pulsação e número de passes foram submetidos à medição de tensões residuais em um difratômetro de Raios-X. As amostras também foram submetidas a análises metalográficas. Conclui-se que as tensões residuais na superfície externa dos tubos são de caráter compressivo. O nível de tensões residuais nos tubos cai com o aumento da energia de soldagem e é menor para tubos soldados utilizando pulsação do que com os soldados sem pulsação e, para esse trabalho, não foi influenciado substancialmente pelo número de passes. As amostras analisadas apresentaram microestruturas convencionais para o aço empregado.This work aims in evaluate the effect of orbital TIG welding on the joint's residual stress level, the final microstructure and the superficial aspect of the weld filet, observing the welding energy, number of passes and the type of pulsation effects in small diameter pipes. The test specimens were welded with different energy, pulsation and number of passes levels and after that it were submitted to residual stress measurement in a X-Ray diffractometer, samples were extracted from the test specimens and it were submitted to metallographic analysis. The ending of this work is that: residual stress in the pipes outer surface are compressive, residual stress level in pipes goes down with increasing welding energy, it is smaller for pipes welded with pulsation and in this work it were not effectively influenced by number of passes

    Full Text Available Background: Since the past two decades, the Lagos seaports have experienced vessel and storage yard cargo congestion, resulting in dwell times of about 30 days for containerised imports and high trade logistics costs. Objectives: The purpose of this study was to identify the critical factors that impact the operational efficiency of the Lagos seaports with a view to improving liner trade activities. Method: The study adopted an operational-based approach to understand the dynamics of the various interfaces of the port value chain. The research paradigm adopted for the study was therefore a combination of constructivism and post-positivism paradigms, which entailed the exploration and understanding of the various stakeholders in the port value chain. The epistemology of the research relied on the use of the exploratory sequential mixed method research technique (i.e. the qualitative approach followed by the quantitative approach at the operational level of port operations. Results: The result of the research showed that significant challenges exist and that some of these challenges cut across all functions of port operations. Challenges are experienced in the areas of corruption, trade fraud, transport infrastructure deficits, the absence of a supply chain culture and shortcomings in the execution of the ‘contract of customs’. Additionally, these factors include the deficiencies in services and facilities provided by state agencies and government-appointed service providers and private sector companies such as truckers, inland container depots, Inland Container Depots (ICDs and terminal operators. Conclusion: Specific recommendations are made to address the issues identified which, if implemented, could significantly address the current inefficiencies observed in the Lagos seaport’s operations.

  7. Recovery and recycling practices in municipal solid waste management in Lagos, Nigeria

    The population of Lagos, the largest city in Nigeria, increased seven times from 1950 to 1980 with a current population of over 10 million inhabitants. The majority of the city's residents are poor. The residents make a heavy demand on resources and, at the same time, generate large quantities of solid waste. Approximately 4 million tonnes of municipal solid waste (MSW) is generated annually in the city, including approximately 0.5 million of untreated industrial waste. This is approximately 1.1 kg/cap/day. Efforts by the various waste management agencies set up by the state government to keep its streets and neighborhoods clean have achieved only minimal success. This is because more than half of these wastes are left uncollected from the streets and the various locations due to the inadequacy and inefficiency of the waste management system. Whilst the benefits of proper solid waste management (SWM), such as increased revenues for municipal bodies, higher productivity rate, improved sanitation standards and better health conditions, cannot be overemphasized, it is important that there is a reduction in the quantity of recoverable materials in residential and commercial waste streams to minimize the problem of MSW disposal. This paper examines the status of recovery and recycling in current waste management practice in Lagos, Nigeria. Existing recovery and recycling patterns, recovery and recycling technologies, approaches to materials recycling, and the types of materials recovered from MSW are reviewed. Based on these, strategies for improving recovery and recycling practices in the management of MSW in Lagos, Nigeria are suggested

    Analyses of an ~ 6 m sediment core from Lago Paixban in Peten, Guatemala, document the complex evolution of a perennial wetland over the last 10,300 years. The basal sediment is comprised of alluvial/colluvial fill deposited in the early Holocene. The absence of pollen and gastropods in the basal sediments suggests intermittently dry conditions until ~ 9000 cal yr. BP (henceforth BP) when the basin began to hold water perennially. Lowland tropical forest taxa dominated the local vegetation at this time. A distinct band of carbonate dating to ~ 8200 BP suggests regionally dry conditions, possibly associated with the 8.2 ka event. Wetter conditions during the Holocene Thermal Maximum are indicated by evidence of a raised water level and an open water lake. The timing of this interval coincides with strengthening of the Central American Monsoon. An abrupt change at 5500 BP involved the development of a sawgrass marsh and onset of peat deposition. The lowest recorded water levels date to 5500–4500 BP. Pollen, isotope, geochemical, and sedimentological data indicate that the coring site was near the edge of the marsh during this period. A rise in the water table after 4500 BP persisted until around 3500 BP. Clay marl deposition from 3500 to 210 BP corresponds to the period of Maya settlement. An increase in δ13C, the presence of Zea pollen, and a reduction in the percentage of forest taxa pollen indicate agricultural activity at this time. In contrast to several nearby paleoenvironmental studies, proxy evidence from Lago Paixban indicates human presence through the Classic/Postclassic period transition (~ 1000 BP) and persisting until the arrival of Europeans. Cessation of human activity around 210 BP resulted in local afforestation and the re-establishment of the current sawgrass marsh at Lago Paixban.

  9. Lake-level variations and tides in Lago Argentino, Patagonia: insights from pressure tide gauge records

    2015-08-01

    Full Text Available Based on precise pressure tide gauge observations lake-level records are derived for two sites in Lago Argentino, southern Patagonia, of 2.5 and 1 years of duration. Applying the tools of time series analysis, the principal processes affecting the lake level are identified and quantified. Lake-level changes reflecting variations in lake volume are dominated by a seasonal cycle of 1.2 m in amplitude. Lake-volume changes occur in addition with a daily period in response to melt water influx from surrounding glaciers. Sporadic lake-volume jumps are caused by bursting of the ice dam of Perito Moreno glacier. Water movements in Lago Argentino are dominated by surface seiches reaching 20 cm in amplitude. Lake tides reach a maximum amplitude of 3 mm. The comparison of the tidal signal extracted from the lake-level observations with a model composed of the contributions of body tide and ocean tidal loading indicates a phase shift of 23° which is most likely explained by an 1 hour phase lag of global ocean tide models in the region of the highly fragmented Pacific coast. The comparison of the obtained results with those of a previous study of Lago Fagnano, Tierra del Fuego, allows to relate differences in the hydrological and hydrodynamic processes between both lakes to morphological properties. This leads to a tentative prediction of the lake-level variability to be expected from other great Patagonian lakes. The presented geodetic results shall serve as a starting point for a detailed limnological investigation of these aquatic ecosystems.

    Full Text Available Aquaculture has shown capacities to serve as means of livelihood, improve living standards, provide employment and generate foreign exchange in many countries. Recent investment in Nigerian aquaculture has been target towards catfish farming. However, small quantity and poor quality fish seeds are one of the problems limiting production. Consequently, Lagos State government introduced improved breeding and hatchery management practices as a package to fish hatchery operators with the aim of improving fish seed quantity and quality in the state. Nevertheless, the dissemination of the package has not yielded the desired result. This study assessed the constraints to adoption of improved hatchery management practices among catfish farmers in Lagos State. With structured questionnaire, 150 catfish farmers, randomly selected from 12 local government areas spread across Lagos State were interviewed. Despite that majority of the respondents strongly agreed or agreed to the fact that improved hatchery management practices have positive impacts on breeding, hatching, and survival of fish fry, majority of them affirmed that high cost of acquisition, high technicality in using the improved management practices as well as inadequate information about the improved management practices are primary reasons for non-adoption of some of the improved practices. Some of the limitations faced by the respondents include insufficient capital, lack of technical expertise to use the methods adequately, non-availability of inputs, expensive cost of facility maintenance, poor information dissemination and insufficient technical support from the extension agents and the state government. Although the adoption of improved practices has not been total, due to these constraints, the farmers’ knowledge of the improved hatchery management practices is broad. There is a need for the state government to subsidize the improved hatchery technologies and inputs, in addition to

    Full Text Available Background: The Lagos State Regulation of Smoking Law was passed in February 2014 and stipulates the total restriction of tobacco smoking in listed public places. Workers in hospitality venues are at a high risk of exposure to second-hand smoke (SHS. Therefore, their awareness of the health risks, attitudes toward SHS and their reported levels of exposure may play a crucial role in developing an effective monitoring, implementation, and enforcement mechanism. Methods: We conducted a cross-sectional, descriptive study among workers in restaurants, bars, and nightclubs registered with the Lagos State Ministry of Tourism in the second quarter of the year 2014. We used a multistage sampling technique to select one respondent each from the 300 centers randomly selected to participate in the survey. Data were collected using a modified version of the World Health Organization Global tobacco surveillance system tools. Univariate and bivariate analysis were carried out. Exposure to SHS in the workplace and in other public places was treated as the outcome variable in the bivariate analysis. Results: Majority (75.3% of the respondents were aged between 21 and 40 years with a mean age of 27.7 + 8.6 years. Many (66% were waiters/waitresses and spent more than 8 h a day. Most (60.6% of the venues were indoor only establishments, and 26.8% had no form of smoking restrictions. Majority of the respondents were exposed to SHS at work, and this was higher in bars and nightclubs. A bivariate analysis of results showed that workers were exposed to SHS at work irrespective of workplace smoking restrictions or respondents smoking status. Conclusion: Our study demonstrates that second-hand smoke exposure is very high (65% in smokers; 65.6% in nonsmokers among workers in restaurants, bars, and nightclubs in Lagos State. We are therefore of the opinion that strict enforcement of law would ensure the protection of these workers.

    The U.S. Geological Survey, in cooperation with the Puerto Rico Electric Power Authority, completed a hydrologic and hydraulic study to assess the potential hazard to human life and property associated with the hypothetical failure of the Lago de Matrullas Dam, located within the headwaters of the Río Grande de Manatí. The hydrologic study yielded outflow hydrographs and peak discharges for Lago de Matrullas and other subbasins in the Río Grande de Manatí hydrographic basin for three extreme rainfall events: (1) a 6-hour probable maximum precipitation (PMP) event, (2) a 24-hour PMP event, and (3) a 100-year-recurrence, 24-hour rainfall event. The hydraulic study simulated the hypothetical dam failure of Lago de Matrullas using hypothetical flood hydrographs generated from the hydrologic study and selected dam breach parameters. The flood wave resulting from the failure was downstream-routed through the lower reaches of the Río Matrullas, the Río Toro Negro, and the Río Grande de Manatí for determination of water-surface profiles developed from the event-based hydrologic scenarios and “sunny day” (no precipitation) conditions. The Hydrologic Modeling System (HEC–HMS) and the River Analysis System (HEC–RAS) computer programs, developed by the Hydrologic Engineering Center (HEC) of the U.S. Army Corps of Engineers, were used for the hydrologic and hydraulic modeling, respectively. The flow routing in the hydraulic analyses was performed using the unsteady-state flow module available in the HEC–RAS model.

    A modern and efficient infrastructure is a basic necessity for economic development and integration into the global economy. The specific problem was the inadequate and unreliable supply of electricity to manufacturing corporations in Lagos, Nigeria. The purpose of the current quantitative correlational research study was to examine if there was a correlation between electricity supply efficiency and organizational growth and profitability in manufacturing corporations in Lagos, Nigeria. The population of the current correlational research study involved 28 out of 34 manufacturing corporations from various industrial sectors in Lagos, Nigeria, that are listed and traded on the Nigerian Stock Exchange. Spearman rho correlations were used to assess the relationships between independent variables of electricity supply efficiency levels and the dependent variables of organizational growth and profitability. The result of the correlational analysis of the data revealed that there was a statistically significant, strong positive correlation between the Average Gross Income (1998-2007) and Average Actual Electricity supply efficiency level (1998-2007), rho = 0.57; p = 0.002. A statistically significant, strong positive correlation was found between the Average Balance Sheet Size (1998-2007) and Average Actual Electricity Supply Efficiency Level (1998-2007), rho = 0.54; p = 0.003. A statistically significant, strong positive correlation between the Average Profit After Tax (1998-2007) and Average Actual Electricity Supply Efficiency Level (1998-2007), rho = 0.60; p = 0.001, was found. No statistically significant correlation between the Average Return on Investment (1998-2007) and Average Actual Electricity supply efficiency level (1998-2007), rho = 0.19; p = 0.33, was discovered.

    A series of lagoons can be found along the coastline of Rio de Janeiro, in the so-called Regiao dos Lagos. The lagoons differ in size, physicochemical, sedimentological and biological characteristics. Rare examples of litifying microbialites that produce stromatolites, the oldest fossils on Earth, can be found living in this lagoon system. The occurrence of stromatolites in the region is of great scientific interest because it enables the study of possible analogues of the earliest life on Earth. However, this region has been suffering from intense human activities and degradations. Geoconservation planning requires an assessment of the characteristics of the region and its potential threats. The primary goal of this study is to assess physical environmental changes and anthropogenic impacts over the last four decades in Regiao dos Lagos. Using a broad integrative assessment combining remote sensing, GIS, field studies and local knowledge of communities, land-cover and land-use classes were identified, as well as the main human activities impacting the environment. The seasonal and weekend tourism and urban sprawl in this coastal area of Rio de Janeiro triggers the occupation of new areas and the removal of natural vegetation, especially on lagoon margins. This disorderly occupation by an ever increasing population, with both legal and illegal constructions and the subsequent overload of the local infrastructure, e.g. increase of electrical energy consumption, volume of vehicles, pollution in air, water and soil and problems with water supply and wastewater treatment, are hastening the gradual degradation of the lake ecosystem. The main driving forces to environmental changes over the last four decades in Regiao dos Lagos were the change of dense vegetation, saline and bare soil classes into built-up areas, adding to the poor waste treatment and inadequate sewage disposal. This analysis provides a basis for a better control of anthropogenic impacts and

    We report the first in vitro and genetic confirmation of Malarone (GlaxoSmithKline; atovaquone and proguanil hydrochloride) resistance in Plasmodium falciparum acquired in Africa. On presenting with malaria two weeks after returning from a 4-week visit to Lagos, Nigeria without prophylaxis, a male patient was given a standard 3-day treatment course of Malarone. Twenty-eight days later the parasitaemia recrudesced. Parasites were cultured from the blood and the isolate (NGATV01) was shown to be resistant to atovaquone and the antifolate pyrimethamine. The cytochrome b gene of isolate NGATV01 showed a single mutation, Tyr268Asn which has not been seen previously.

    Full Text Available Los lagos de alta montaña, con una baja mineralización, alcalinidad y contenido de nutrientes, son ecosistemas sensibles a perturbaciones naturales o antropogénicas y en la actualidad están amenazados por el calentamiento global. En México existen dos lagos de alta montaña (> 3,800 m snm: La Luna y El Sol, en el cráter del Nevado de Toluca. Análisis de parámetros químicos y de diatomeas en sedimentos superficiales permiten identificar que La Luna es más ácido y menos mineralizado que El Sol y que a pesar de su proximidad geográfica cada lago tiene un conjunto de diatomeas característico, con menor abundancia y riqueza específica en La Luna. En este lago dominan Encyonema perpusillum y Psammothidium helveticum y en El Sol Cavinula pseudoscutiformis , Psammothidium levanderi y Aulacoseira distans. Con base en esta distribución se interpreta el registro de diatomeas de una secuencia sedimentaria de La Luna, de 57 cm, fechada con 210 Pb y 14 C en la que también se realizaron análisis de contenido de cladóceros y de susceptibilidad magnética. Todos estos indicadores permiten ubicar el inicio de una tendencia hacia climas secos y fríos alrededor de los años 1350 y 1510, que corresponde a la Pequeña Edad de Hielo (PEH, la cual tiene su máxima expresión entre los años 1660 y 1760, durante el mínimo de actividad solar de Maunder. Las características ambientales de sequía y frío se observan hasta principios del siglo XX. La comparación de este registro con otros disponibles permite concluir que durante la PEH hubo una tendencia regional en el centro de México hacia climas secos.

    2010-06-01

    Full Text Available Abstract Background Two major cities in West Africa, Accra, the capital of Ghana, and Lagos, the largest city of Nigeria, have significant problems with substandard pharmaceuticals. Both have actively combated the problem in recent years, particularly by screening products on the market using the Global Pharma Health Fund e.V. Minilab® protocol. Random sampling of medicines from the two cities at least twice over the past 30 months allows a tentative assessment of whether improvements in drug quality have occurred. Since intelligence provided by investigators indicates that some counterfeit producers may be adapting products to pass Minilab tests, the results are compared with those from a Raman spectrometer and discrepancies are discussed. Methods Between mid-2007 and early-2010, samples of anti-malarial drugs were bought covertly from pharmacies in Lagos on three different occasions (October 2007, December 2008, February 2010, and from pharmacies in Accra on two different occasions (October 2007, February 2010. All samples were tested using the Minilab® protocol, which includes disintegration and active ingredient assays as well as visual inspection, and most samples were also tested by Raman spectrometry. Results In Lagos, the failure rate in the 2010 sampling fell to 29% of the 2007 finding using the Minilab® protocol, 53% using Raman spectrometry, and 46% using visual inspection. In Accra, the failure rate in the 2010 sampling fell to 54% of the 2007 finding using the Minilab® protocol, 72% using Raman spectrometry, and 90% using visual inspection. Conclusions The evidence presented shows that drug quality is probably improving in both cities, especially Lagos, since major reductions of failure rates over time occur with all means of assessment. Many more samples failed when examined by Raman spectrometry than by Minilab® protocol. The discrepancy is most likely caused by the two techniques measuring different aspects of the medication

Uma destas finalidades é o Cadastro Técnico Rural Municipal (CTRM, o que exige que seja conhecida a magnitude dos erros inerentes ao processo. Foi desenvolvido um estudo para quantificar a imprecisão originada do uso direto, sem restituição, destas aerofotos, nas duas principais formas de entrada da informação espacial nesses sistemas: a digitalização manual, via mesa digitalizadora, utilizando-se osistema CR-SIGDER 2.0; e a digitalização eletrônica, via "scanner", com vetorizaçãio direta no monitor SVGA, com "mouse", utilizando-se o sistema CR-IMAREA 1.0. Os pontos de apoio para transformação de escalas foram georreferenciados aosistema UTM através de GPS e topografia. O principal parâmetro analisado foi o erro médio de posicionamento nas coordenadas. Procurou-se, ainda, descobrir qual a melhor distribuição dos pontos de apoio de campo para a transformação de escalas nestes sistemas. A melhor distribuição de pontos apresentou um erro médio de posicionamento nas coordenadas de 6.96 metros para a mesa digitalizadora, e de 7.53 metros para o monitor SVGA. Levando-se em consideração a pequena escala utilizada, estes resultados mostram o grande potencial das aerofotos de pequeno formato para as finalidades propostas neste trabalho, pois os mesmos se traduzem em erros de distâncias e áreas dentro da tolerância topográfica, desde que os pontos de apoio esfejam distribuídos um em cada canto da aerofoto.The lack of cartographic base for cartain regions, has taken to a more intensive use of aerial photographies of small format as a source of agile spatial information and of a low cost to the system users which treat georeferencing images to several

    Full Text Available A abundância e a distribuição mensal de larvas de peixes no Lago Catalão, situado próximo ao encontro dos rios Solimões e Negro, foram avaliadas entre os meses de janeiro e maio de 2001. As amostras foram coletadas com uma rede de ictioplâncton cônico-cilíndrica (350 µm de malha, Ø 0,3 m e 2 m de comprimento, com um fluxômetro acoplado na boca da rede para a obtenção do volume de água filtrado pela mesma. As variáveis categóricas consideradas foram: posição no lago (margem e centro, profundidade (superfície e fundo e turno (diurno e noturno; tendo sido realizada a Análise Fatorial de Correspondência (AFC usando a densidade larval (larvas. m-3 como variável resposta e os meses como descritores. A AFC discriminou a ocorrência de larvas por unidade experimental entre o mês de janeiro e os demais meses, com 58,15% de inércia, e a densidade larval mudou conforme a posição no lago e o período do dia. A maior parte das larvas era protolarva e alimentava-se na margem, tanto na superfície quanto no fundo do lago. Concluiu-se que o Lago Catalão é um importante berçário para as larvas dos peixes que desovam no rio Solimões e também para as larvas dos peixes que desovam no próprio lago.The abundance and monthly distribution of fish larvae in Catalão Lake, situated near the confluence of the Solimões and Negro River was evaluated between January and May 2001.

    Full Text Available Sexual violence against females is a public health problem. This descriptive cross-sectional study sought to determine the prevalence of sexual violence among out-of-school female adolescents in Lagos, Nigeria and examine the context in which it occurs. Three hundred and fifty adolescents, between the ages of 10 and 19 years, working in Sandgrouse market, Lagos, were selected using cluster sampling. Data were collected using an interviewer-administered questionnaire. Almost half (42.9% of the respondents have had sexual intercourse, and median age at initiation was 17 years. Forced initiation was reported by 15.8%, and 36.3% reported that first intercourse was due to coercion. Among the sexually active, only 12.3% stated that “it is what they desire.” Majority of respondents (64.1% believe that rape is common in their community, and 18% of the sexually active have experienced rape. Out-of-school adolescents in this community are at risk of sexual violence. The factors that make them vulnerable need to be addressed.

    Full Text Available The phenomenon of climate change heralds distinctive challenges for sub-Saharan Africa’s urban areas, with economic, social, and health impacts, and severe effects on housing and infrastructure. This study examined climate-change induced vulnerabilities including the urban housing crisis and homelessness in the context of Lagos mega-city, Nigeria, with a view to defining the potential lessons to learn from the Asian urban experience. The study conducted case-study analyses of Lagos and the Asian urban experience, highlighting the megacity-related vulnerabilities. It identified gender and aging as key factors in understanding vulnerability. Lessons from Asia relate to: the conscious policy-linkage of urban demographic expansion and economic growth; synergy between formal and informal sectors; urban densification through compact, mixed-land use development; broad-based urbanization; metropolitan expansion; pursuit of slum-free cities; prominence of housing in national policies; pro-poor financial frameworks; and extensive adoption of mitigation and adaptation strategies in the coastal conurbations. The paper concluded on the critical role of urban governance in reducing vulnerability, the need for greater multi-disciplinary stakeholders’ collaboration and partnership, and the expediency of fitting adaptation strategies and resilience responses to specific needs, capacities and priorities of impact groups. These could enhance the transformation of mega-cities into more adaptable and resilient urban systems.

    Full Text Available The study assessed allocation, criteria and allotment effectiveness of performance risks in Build- Operate-Transfer (BOT transportation infrastructure in Nigeria using Lagos Infrastructure Project (LIP as a case study. LIP is the only BOT-procured tolled road that has attained ‘operate’ stage of BOT cycle in Nigeria. It revealed that more operating risks were actually allocated to the concessionaire than the grantor and most of the risks were preferred retained by the allottee. Significant fraction of the risks was effectively allocated between the concessionaire and grantor except those that involve close interface between participants. While grantor rated nine risks high and seven risks very high; the concessionaire assessed nine risks to be high and five risks to be very high; the grantor rated the effectiveness level to be seventy three per cent and the concessionaire assessed it to be sixty four per cent. The study recommended that the evolving knowledge from Lagos Infrastructure Project (LIP should be documented to guide future BOT transactions in Nigeria.

    Retinopathy of prematurity (ROP), thought to be rare in Nigeria, sub-Saharan Africa, has been reported in recent studies. Developing cost-effective screening is crucial for detecting retinal changes amenable to treatment. This study describes the use of an iPhone combined with a 20-D lens in screening for ROP in Lagos, Nigeria. The ROP screening program was approved by the Lagos University Teaching Hospital Ethical Committee. Preterm infants with birthweight of less than 1.5 kg or gestational age of less than 32 weeks were screened. In conjunction with the neonatologist, topical tropicamide (0.5%) and phenylephrine (2.5%) was used to dilate the pupils. A pediatric lid speculum was used. Indirect ophthalmoscopy was used to examine the fundus to ensure there were no missed diagnoses. An iPhone 5 with 20-D lens was used to examine the fundus. The App Filmic Pro was launched in the video mode. The camera flash served as the source of illumination. Its intensity was controlled by the app. The 20-D lens was used to capture the image of the retina, which was picked up by the camera system of the mobile phone. Another app, Aviary, was used to edit the picture. The images captured by the system were satisfactory for staging and determining the need for treatment. An iPhone combined with a 20-D lens appear to be useful in screening for ROP in resource-poor settings. More studies are needed in this area.

  14. Private sector participation in domestic waste management in informal settlements in Lagos, Nigeria.

    2016-12-01

    Lagos is one of the fastest growing cities in Africa, which is grappling with the challenges of poorly managed urbanisation. With an estimated population of about 17.5 million, solid waste management is one of the most pressing environmental challenges currently faced in the city. It is estimated that more than 9071847.4kg of urban waste is generated every day in the city. The city lacks the capacity to deal with such magnitude of waste. Consequently, the city has involved the private sector (private sector participation) in its waste management drive. This article examines the effectiveness of this public-private sector collaboration model in waste management in informal settlements in Lagos using empirical data. Major findings of the article include the irregularity of waste collection owing to a poor road network, an inadequate transport infrastructure and the desire to maximise profit, as well as poor waste handling and disposal methods by the private sector participation operators who are not chosen based on competence and capacity to perform. Another major finding is the lack of cooperation from residents evidenced in non-payment of bills and poor packaging of wastes, resulting in wastes being littered. The article concludes on the need to restructure the scheme through proper sensitisation of residents, selection of operators with demonstrable delivery capacity and provision of a well-maintained road network to facilitate access of operators to settlements. © The Author(s) 2016.

    Solid waste management in Lagos, Nigeria includes refuse collection and transportation to a landfill site. Disposal of the refuse and maintenance of the landfill site is also included in this task which, in the past was always a responsibility of the Government Agencies at the local level as a social service. This service has recently been privatised in the name of Private Sector Participation (PSP) in domestic refuse collection and disposal. As a new operator in about 23 wards in the ongoing PSP of domestic refuse, Richbol Environmental Ltd., recognized the enormous effort that government will have to make to sustain PSP in solid waste management. Governments can maintain control through re-orientation, legislation, enforcement, strengthening the PSP operators, integrating existing operators, and monitoring the activities of PSP operators. This paper presented a brief overview of the institutional changes that solid waste management has undergone in Lagos since 1977. It was emphasized that integrated waste management is extremely capital intensive. An integrated PSP can be a long term solution to waste management in developing, cash poor countries. The economic importance of PSP lies in the fact that it will reduce government expenditure and will also create a healthier environment and provide employment opportunities for thousands of employees and contribute to the gross domestic product of the country. 5 refs., 3 tabs., 1 fig.

    Several body of knowledge have noted the importance of wetland ecosystems in climate moderation, resource supply and flood risk reduction amongst others. Relevant as it may, rapidly increasing population and uncontrolled urban development poses a challenge in some regions and require understanding of the ecosystem components and drivers of change over a long period of time. Thus, the main thrust of this paper is to analyse multiple drivers of wetland ecosystems degradation in the last 30 years in the Lagos megacity using field study, desktop review, satellite data and laboratory analysis. Key drivers identified includes: conversion of wetlands to settlements and waste sink, land use planning that neglects wetland conservation and restoration, ineffective legal status for wetlands, over exploitation leading to degradation and fragmentation of wetland ecosystems governance. In stemming further loss of this vital ecosystem, this study adopted and proposed respectively, the Drivers, Pressure, State, Impact and Response (DPSIR) and Integrated Planning Approach (IPA) frameworks in analysing policy and governance issues in wetland development. These analyses figured out amongst others, strict conservation and sustainable use of wetland resources, habitat restoration, climate adaptation measures, legal protection and wetland management institution as major responses to current multiple pressures facing wetland ecosystems in Lagos. For these frameworks to be made meaningful, weak coordination among government agencies and institutional capacity in implementation and law enforcement, unsustainable resource extraction by private/business organization and issues on alternative sources of income on the part of the local communities amongst others needs to be addressed.

Respondents were required to rate their own health as "excellent, very good, good, fair, poor and very poor". The questionnaire contained questions on various aspect of the respondents neighborhood and their perception about them. It was found that most neighborhoods in Lagos State are deprived of basic essentials of life such as electricity, water, good roads and security. Over 43% of the respondents claimed to have visited a hospital two or more times and 43.7% had lost at least two neighbors in the past one year. Over half (57.8% of the respondents rated their own health as good, 36.6% ranked their own health as fair while only 5.6% claimed to have poor health. A fitted regression model ( r2 = 0.644 showed that variables such as number of dependants, income, occupation, type of residential accommodation, ownership of house, number of rooms occupied, mode and convenience of transportation, accessibility to water, electricity and good roads and security jointly determine the perception of an individual about his own health status.Key Words: Neighborhood, Deprivation, Self Rated Health, Security, ResidenceDOI = 10.3126/dsaj.v2i0.1364Dhaulagiri Journal of Sociology and Anthropology Vol.2 pp.193-210

    Thermoluminescence (TL) and optically stimulated luminescence (OSL) dating are two important techniques for dating archaeological and geological material, especially suitable for archaeological ceramics, where samples for 14 C dating are not available. In this work, five pottery shards from Osvaldo and Lago Grande archaeological sites were dated by OSL. For measurements, it was used the SAR protocol. The annual dose rates were estimated by the contents of U, Th and K, determined by instrumental neutron activation analysis (INAA) of the pottery shards and clay samples near both sites. Lago Grande and Osvaldo represent a microcosm of the region, and their proximity and high density of archaeological record turn them interesting to study possible relations of cultural and/or commercial exchange. Calculations showed that the water content is an important variable that cannot be neglected in OSL dating of pottery shards from central Amazon, due to the high humidity in regional soils. The results between 867 ± 101 and 1154 ± 62 years AD agreed with the average time span for the archaeological sites occupation found in the literature. (author)

    The macroscopic characteristics of archaeological ceramics, such as the surface decoration and shape, are used as cultural and chronological indicators of ancient people. The combination of stylistic-typological studies with archaeometric analysis, as provenance studies, has been considered of great importance in Archaeology. The purpose of this paper is to contribute to the understanding of the pre-colonial Amazonian occupations. Inside this context, fifty ceramic fragments from the Lago Grande archaeological site were analyzed by INAA in order to characterize its elemental composition. The results were treated with multivariate statistics: Cluster, Principal Components and Discriminant Analysis. The results obtained by these three methods were compared in an effort to achieve some correlation with the archaeological context. It was stated the existence of two different groups of artifacts. They probably regard to the main ceramic phases found in the site excavation: Paredao and Manacapuru. Once confirmed by other archaeological analyses, these results could corroborate an exchange net among the former inhabitants of Lago Grande and other sites in the neighborhood. (author)

    This study sought to determine the oral health care knowledge and practices of a group of deaf adolescents in Lagos. The study involved 50 students of Wesley School 1 for the Deaf, Lagos (26 males and 24 females, aged 10-19 years, mean 13.3 +/- 2.8). Information about previous dental care, oral hygiene, and snacking habits were obtained through a questionnaire and sign language by the teachers. Only 12 percent of pupils had received dental care. Eight percent and 72 percent, respectively, gave correct answers to causes of tooth decay and bleeding gums. Ninety-four percent brushed their teeth once daily, with no significant sex difference (P > .05). Reported dental problems include bleeding gums (36%), tooth discoloration, and tooth decay. The majority of pupils (60%) preferred biscuits and soft drinks as snacks. More than 90 percent were willing to have a dental check-up. The oral health knowledge and practices of this group of children will improve through a controlled school-based oral health education program.

    Full Text Available This study aimed at looking at the influence of counseling services on perceived academic performance of secondary school students in Lagos State. At the first stage, the researchers purposively selected Ikorodu L.G.A in Lagos State. At the researchers selected two schools (1 Private schools, & 1 Public schools, using simple random technique. Thus, a total of two schools were picked in each of the L.G.A. Finally, simple random sampling was used in selecting eighty students in each L.G.A, thus making a total of two hundred and forty Senior Secondary students that participated in the study. Six hypotheses were generated for the purpose of this study. Data were gathered using a researcher designed instrument tagged “Influence of Counselling Service on Academic Performance of Students Questionnaire (ICAPSQ. The findings of this study showed that there was no significant difference on the basis of age, class level and school type. However a significant difference was found on the basis of respondent’s religion, gender and the number of times the students visited the counselor. It was therefore recommended that the ministry of education should ensure that guidance and counselling units are established in all public and private secondary schools in Nigeria.

    Human papillomavirus (HPV) is one of the most common sexually transmitted infections in sexually active adolescents and young women and has been implicated as a cause of the majority of cases of cervical cancer, which is the second most common cancer in women in Nigeria. HPV is preventable with the use of HPV vaccines. The objective of this study was to assess mothers' HPV knowledge and their willingness to vaccinate their adolescent daughters in Lagos, Nigeria. This study was a community-based, descriptive cross-sectional study carried out in July, 2012 in Shomolu Local Government Area (LGA) of Lagos State, Nigeria. Multistage sampling method was employed to select the 290 respondents who participated in the study. Structured, pretested, interviewer-administered questionnaires were used for data collection. Data was analyzed with Epi Info™ version 7. The study revealed low awareness of HPV (27.9%) and HPV vaccines (19.7%) among the mothers that participated. There was a high awareness for cervical cancer but little knowledge of its link to HPV. Awareness and utilization of HPV vaccines increased with increasing educational level (P knowledge about HPV and HPV vaccines, mothers were willing to vaccinate their daughters. We recommend improving mothers' knowledge by education and the possible inclusion of the vaccine in the national immunization schedule to eliminate the financial barrier.

    Thermoluminescence (TL) and optically stimulated luminescence (OSL) dating are two important techniques for dating archaeological and geological material, especially suitable for archaeological ceramics, where samples for {sup 14}C dating are not available. In this work, five pottery shards from Osvaldo and Lago Grande archaeological sites were dated by OSL. For measurements, it was used the SAR protocol. The annual dose rates were estimated by the contents of U, Th and K, determined by instrumental neutron activation analysis (INAA) of the pottery shards and clay samples near both sites. Lago Grande and Osvaldo represent a microcosm of the region, and their proximity and high density of archaeological record turn them interesting to study possible relations of cultural and/or commercial exchange.

    Across the world, basic medical scientists and physician scientists work on common platforms in state-of-the-arts laboratories doing translational research that occasionally results in bedside application. Biotechnology industries capitalise on useful findings for colossal profit.1 In Nigeria and the rest of Africa, biomedical science has not thrived and the contribution of publications to global high impact journals is low.2 This work investigated facilities available for modern biomedical research in Lagos public universities to extract culprit factors. The two public universities in Lagos, Nigeria were investigated by a cross sectional questionnaire survey of the technical staff manning biomedical science departments. They were asked about availability of 47 modern biomedical science research laboratory components such as cold room and microscopes and six research administration components such as director of research and grants administration. For convenient basic laboratory components such as autoclaves and balances, 50% responses indicated "well maintained and always functional" whereas for less convenient complex, high maintenance, state-of-the-arts equipment 19% responses indicated "well maintained and always functional." Respondents indicated that components of modern biomedical science research administration were 44% of expectation. The survey reveal a deficit in state-of the-arts research equipment and also a deficit in high maintenance, expensive equipment indicating that biomedical science in the investigated environment lacks the momentum of global trends and also lacks buoyant funding. In addition, administration supporting biomedical science is below expectation and may also account for the low contributions of research articles to global high impact journals.

    Full Text Available El presente artículo aborda el proceso de reapropiación del lago de Chapala, México. En las últimas décadas se han venido transformando el suelo y la producción agrícola en los municipios ribereños del lago de Chapala debido a la introducción de cultivos de exportación mediante sistemas modernos de producción tecnificada. Por lo que los cultivos tradicionales han ido disminuyendo o se producen con mayor uso de pesticidas, fertilizantes y agroquímicos. El papel del campesino ribereño también se ha modificado debido a que las agroempresas trasnacionales generan una estructura de renta o compra de suelos y parcelas que utilizan durante un periodo de años, perdiendo el dueño el uso de sus tierras a cambio de un ingreso seguro. En el escenario ribereño actual, el campesino se transforma en receptor económico y, en ocasiones, en trabajador de sus propias tierras, sin posibilidad de decisión sobre ellas. Por lo que se encuentran en peligro los saberes locales históricos de las poblaciones ribereñas así como su cultura lacustre.

Desde 2009 se han observado floraciones extensivas de cianobacterias en el lago, reflejando la contaminación del agua en la cuenca. Se determinaron los niveles de arsénico (As y mercurio (Hg en agua superficial del lago de Atitlán, por espectrofotometría de absorción atómica (EAA, en cuatro muestreos realizados en marzo, mayo, agosto y octubre de 2014 en 14 sitios. Diez sitios se encuentran localizados en el lago, habiendo sido definidos en estudios anteriores con base en su cercanía a poblaciones asentadas en la orillas del lago. Dos sitios corresponden a los principales ríos tributarios, y los restantes dos sitios a la entrada y salida de la planta de tratamiento Los Cebollales, ubicada en Panajachel. Los niveles de As encontrados en el lago de Atitlán, tributarios y en la planta de tratamiento, fueron superiores a 20 μg/L. Los resultados indican que la contaminación del lago de Atitlán por As se debe principalmente a la geología de la cuenca, al localizarse en una zona volcánica. Los niveles cuantificables de As, son superiores al nivel máximo permitido para agua potable en la Norma de Agua Potable (NGO 29001:99 de la Comisión Guatemalteca de Normas (COGUANOR, por lo que el agua del lago de Atitlán no se considera apta para el consumo humano.

    Full Text Available Resumo Vivemos uma crise de autoridade no mundo moderno e seu impacto no âmbito educacional tem sido objeto de análises e críticas sob diferentes perspectivas. De acordo com Hannah Arendt, esse não é um fenômeno gerado na esfera da educação, não obstante, seu impacto nesse âmbito apareça aos olhos da autora como o sintoma mais evidente da profundidade e seriedade desta crise. Este trabalho tem por objetivo analisar o conceito de autoridade na obra de Hannah Arendt, propondo uma abordagem que busca romper com as perspectivas que veem a autoridade como um epifenômeno do poder. Desse modo, busca-se lançar um olhar sobre a autoridade como um elemento consubstancial à educação e não como um mero instrumento de poder, submissão e sujeição de indivíduos. Assim, num primeiro momento, será apresentada a perspectiva de Alain Renaut, filósofo francês que, em sua abordagem da autoridade, dialoga direta e criticamente com Arendt. Em seguida, será apresentada a origem do conceito sob a perspectiva de Hannah Arendt, bem como sua relação com a educação.

    Full Text Available La relación entre la fluorescencia variable y la fluorescencia máxima (Fv/Fm de las comunidades de algas se ha utilizado comúnmente como una medida de la eficiencia fotosintética del fitoplancton. Dicha eficiencia puede estar afectada por la localización de los ambientes acuáticos en distintas provincias limnológicas. En este trabajo se quiso establecer la diferencia en la relación Fv/Fm entre el lago Boa (150 msnm, Amazonía colombiana y el lago Guatavita (3000 msnm, cordillera oriental de los Andes colombianos. Los promedios de las eficiencias medidas fueron en general bajos (0,212 a 0,367 y 0,089 a 0,32 en los lagos Boa y Guatavita, respectivamente, lo que señala estrés fisiológico para las algas. La eficiencia fue mayor en aguas intermedias y presentó cambios fuertes entre épocas de muestreo y entre ecosistemas. En aguas superficiales se presentó fotoinhibición, la cual fue más fuerte en Guatavita. La eficiencia fotosintética fue menor en el lago andino debido posiblemente a diferencias climáticas, de altura sobre el nivel del mar y de estratificación. Durante los ensayos de laboratorio se observó que la eficiencia disminuyó con el tiempo, lo cual pudo deberse a una aclimatación de las algas a la oscuridad. Los datos de laboratorio confirmaron que el fitoplancton epilimnético del lago Guatavita estuvo fotoinhibido en la época de estratificación.Commonly relation between variable fluorescence and maximum fluorescence (Fv/Fm of the algae community has been utilized like a measure of the phytoplanktonic photosynthetic efficiency.

    um cavalo e seu retrato, a partir dos sentimentos contraditórios de seu dono, que considera um crime aquele clique. Temos aí um retrato, imagem subtraída ilicitamente ao seu dono: escrita, representação. Temos também uma narrativa, escrita do retrato, representação da representação. Este artigo pretende mostrar como Guimarães Rosa manipula as ambiguidades da linguagem literária, levando-a além dos limites da representação, explorando seu fascínio, seu saber, que não é da ordem da compreensão. O cavalo e seu retrato fazem refletir sobre a literatura, sobre seu excesso de verdade que compõe sua mentira. Ao escrever o cavalo e seu retrato, o texto não consegue fixar nenhuma verdade, apenas imagens fugidias que compõem recapítulos: há sempre um escrito a se sobrepor a outro, sem determinar onde está o verdadeiro, onde está o que o nega, a remeter o olhar ao reino da fascinação, onde a imagem perde o valor de significação para se tornar pura paixão da indeterminação, da indiferença.

Las bacterias fueron multiplicadas in vitro, usando como sustrato el carbono orgánico disuelto (COD del lago en cada una de las regiones estudiadas, para posterior análisis de la abundancia de isotopos estables de carbono y nitrógeno. Estos datos fueron confrontados con los valores de COD de los cuatro periodos limnológicos del lago (seca, inundación, llena y bajada de aguas. En general se encontró que la fuente principal de carbono de las bacterias heterotróficas fue aquella de origen C4, que presentó un aporte mínimo de 75%, en la medida en que el δ13C de las bacterias presentó valor medio de -17,72‰ ± 2,25. Confrontando ese valor, con el δ13C del zooplancton en el mismo período (-33,04‰±3,81 se concluye que el aporte de las bacterias heterotróficas al flujo de carbono hacia niveles tróficos superiores en el lago estudiado es mínimo.

    Full Text Available O presente estudo foi realizado com o objetivo de compreender como os traços culturais brasileiros se manifestam nas relações de troca comercial entre funcionários de micro e pequenas empresas varejistas e seus consumidores. Como, na área de marketing, uma das perspectivas teóricas que buscam dar conta das relações entre empresas e consumidores é o marketing de relacionamento, procurou-se compreender as trocas tendo também esta perspectiva como suporte. Partindo do pressuposto de que a relação de troca comercial é também uma relação humana e social, procurou-se tratar a troca como um fenômeno social. A pesquisa, de natureza qualitativa, foi realizada em cinco empresas varejistas de um município de pequeno porte no Sul de Minas Gerais – um supermercado, uma farmácia, uma panificadora, um posto de combustíveis e uma loja de hortifrutigranjeiros – durante o período de um ano (dez/2008 a dez/2009 utilizando-se como método a etnografia. A observação participante e a entrevista em profundidade foram utilizadas como técnica de coleta de dados. Quanto aos resultados, evidenciou-se como o personalismo, a cordialidade, a não valorização do trabalho manual, a aversão ao conflito, a malandragem e o jeitinho se manifestaram nas relações comerciais. A principal conclusão a que se chegou é a de que a realidade das trocas comerciais no varejo é complexa e multifacetada tanto quanto o é a cultura brasileira. No final deste trabalho, são apresentadas as implicações teóricas e metodológicas para a área acadêmica de marketing e as implicações gerenciais, especialmente para as empresas varejistas.

    Full Text Available Em 1996 a carga tributária das Microempresas (ME e Empresas de Pequeno Porte (EPP foi reduzida por meio da criação do Sistema Integrado de Pagamento de Impostos e Contribuições das Microempresas e das Empresas de Pequeno Porte (SIMPLES, que é um regime especial unificado de arrecadação de tributos e contribuições. Essa redução da carga tributária representa uma importante renúncia de receita ao Estado, o que representa um custo para o país e justifica a importância do seu estudo. Assim, o objetivo do presente artigo é fazer uma análise da arrecadação do SIMPLES e do SIMPLES Nacional e da geração de empregos pelas ME, EPP e pelos Microempreendedores Individuais (MEI, para verificar benefícios à sociedade. Como instrumento de pesquisa, utilizou-se revisão bibliográfica, coleta de dados para o período de 2002 a 2013 e análise desses dados por meio de estatística descritiva. Foi verificado que a arrecadação tributária pelo SIMPLES apresentou um crescimento mais de três vezes superior ao crescimento da arrecadação dos outros regimes, no período de 2007 a 2013. Além disso, observa-se que apesar das ME, EPP e MEI possuírem participação expressiva no número de empregos, essa participação reduziu no período estudado. Constatou-se que a partir de 2009, com a influência dos MEI, a arrecadação média por empresa no SIMPLES tem apresentado diminuição.In 1996, Microenterprises' (ME and Small Enterprises' (EPP tax burden was reduced by the creation of the Integrated System for Payment of Taxes and Contributions of Micro and Small Enterprises (SIMPLES, which is a special unified regime applied to collect federal taxes and contributions of such companies. This tax reduction is an important waiver of revenue to the state, which represents a cost to the country and justifies the importance of this study. The objective of this paper is to analyze the collection of 'SIMPLES' tax and the consequent generation of jobs

    Full Text Available O monorquidismo é um quadro raramente descrito em equinos, que não apresenta descrições prévias na literatura nacional. Trata-se de um equino adulto brasileiro, com oito anos de idade, sem raça definida, porém com características de raças de origem nacional. Por abordagem inguinal do lado esquerdo, localizou-se a túnica vaginal intacta, que, aberta, continha a cauda de um epidídimo mal formado, o ducto deferente e um delgado pedículo vascular, mas sem indícios de testículo. Exames histológicos e hormonais confirmaram a ausência de tecido testicular. Conclui-se que os exames histológicos e hormonais são essenciais para o diagnóstico de monorquidismo que, apesar de raro, também pode acometer equinos nacionais

    Full Text Available Este ensaio perscruta uma noção de real e de ficção em que ambos surgem como representação, num processo de semiose considerada um paradoxo comunicativo. O jornalismo contemporâneo é também uma mercadoria, um sistema complexo de comunicação, seu produto é a realidade construída com argumentos estereotipados por interesses editoriais pautados por interesses políticos e comerciais, simulacro de um conteúdo que não reflete, mas cria a necessidade no receptor. Também a realidade construída pelas imagens contemporâneas não é comunicação no sentido designativo, mas expressão de um simulacro que, como tal, ao negar a fantasia, recalca a realidade como uma ficção, operando num sistema de códigos numéricos que surgem como imagem num espaço visual transduzido da sua indexalidade para a virtualidade.

    There is never a better time for this study than now when Nigeria as a country is going through the worst time in power supply. In Lagos city about 12,000 tons of waste is generated daily, and is expected to increase as the city adds more population. The management of these waste has generated great concern among professionals, academia and government agencies. This study examined the regenerative management of organic waste, which accounts for about 45% of the total waste generated in Lagos. To do this, two management scenarios were developed: landfill methane to electricity and compost; and analyzed using data collected during field work and from government reports. While it is understood that landfilling waste is the least sustainable option, this study argued that it could be a viable method for developing countries. Using U.S EPA LandGEM and the IPCC model, estimates of capturable landfill methane gas was derived for three landfills studied. Furthermore, a 35-year projection of waste and landfill methane was done for three newly proposed landfills. Assumptions were made that these new landfills will be sanitary. It was established that an average of 919,480,928m3 methane gas could be captured to generate an average of 9,687,176 MW of electricity annually. This makes it a significant source of power supply to a city that suffers from incessant power outages. Analysis of composting organics in Lagos was also done using descriptive method. Although, it could be argued that composting is the most regenerative way of managing organics, but it has some problems associated with it. Earthcare Compost Company processes an average of 600 tons of organics on a daily basis. The fraction of waste processed is infinitesimal compared to the rate of waste generated. One major issue identified in this study as an obstacle to extensive use of this method is the marketability of compost. The study therefore suggests that government should focus on getting the best out of the

    Full Text Available RESUMO: Este artigo procura refletir sobre performances narrativas produzidas por crianças imigrantes em um contexto escolar marcado por intensa diversidade cultural. A análise foi fundamentada nos dados obtidos por meio da pesquisa etnográfico-propositiva intitulada Pequenos Narradores, realizada entre os anos de 2014 e 2015, em duas escolas públicas de ensino fundamental de Paris, França, nas chamadas CLIN - classes de iniciação do francês para crianças não francófonas. Como estratégia metodológica, foram realizadas diversas atividades lúdicas no sentido de favorecer a produção narrativa na sala de aula. A agência das crianças na escolha do que e como contar foi analisada sob a perspectiva dos estudos da performance. Constatou-se que, nesse contexto, as performances narrativas constituem um elemento importante não apenas na tradução e organização das experiências dessas crianças imigrantes, mas, sobretudo, na criação e transformação dessas experiências diante da realidade de vida no novo país.

    Full Text Available As Comunidades Eclesiais de Base, como experiência inovadora no jeito de ser Igreja, foram sempre motivo de reações diversificadas no Brasil e no mundo. A grande novidade desta caminhada eclesial consiste em apontar a possibilidade concreta de uma incidência críticoprofética da Igreja, capaz de um exercício alternativo de solidariedade com os pequenos e excluídos. Para alguns setores da mídia e da intelectualidade, esta experiência estaria hoje vivendo um tempo de esgotamento e crise, sobretudo, após o clima de dissolução da utopia socialista, com o ocaso do socialismo real e a queda do muro de Berlim. Alguns autores chegam mesmo a falar que a experiência encontra-se, hoje, em "visível declínio", restando apenas compor os últimos acordes do "réquiem libertador".

    Full Text Available RESUMO A execução de um projeto florestal deve ser norteada por ferramentas de análise econômica, de forma que se possa respaldar os investimentos realizados. Objetivou-se neste trabalho promover uma análise econômica e de sensibilidade em projetos de reflorestamento de eucalipto na microrregião de Vitória da Conquista, BA. Utilizou-se como critério o Valor Presente Líquido, a Taxa Interna de Retorno, o Valor Periódico Equivalente e o Custo Médio de Produção. A análise de sensibilidade foi realizada através da variação da taxa anual de juros, da produção e do preço da madeira. O custo de implantação apresentou valor de 2.091,92 reais/ha. Se tratando do processo de condução, obteve-se um valor de 915,29 reais/ha, corrigidos para o ano zero. Apesar da característica de longo prazo, a atividade florestal constituiu alternativa de renda para os pequenos produtores, apresentando viabilidade econômica em todos os critérios avaliados.

  14. Reality show: um paradoxo nietzschiano

    Full Text Available

    O fenômeno dos reality shows - e a subseqüente relação entre imagem e verdade - assenta-se sobre uma série de paradoxos. Tais paradoxos podem ser compreendidos à luz do pensamento do filósofo alemão Friedrich Nietzsche, que, através dos usos de formulações paradoxais, concebia a realidade como um mundo de pura aparência e a verdade como um acréscimo ficcional, como um efeito. A ficção é então tomada, na filosofia de Nietzsche, não em seu aspecto falsificante e desrealizador - como sempre pleiteou nossa tradição metafísica -, mas como condição necessária para que certa espécie de invenção possa operar como verdade. Sendo assim, a própria expressão reality show, através de sua formulação paradoxal, engendra explicitamente um mundo de pura aparência, em que a verdade, a parte reality da proposição, é da ordem do suplemento, daquilo que se acrescenta ficcionalmente - como um adjetivo - a show. O ornamento, nesse caso, passa a ocupar o lugar central, apontando para o efeito produzido: o efeito-de-verdade. Seguindo, então, o pensamento nietzschiano e sua atualização na contemporaneidade, investigaremos de que forma os televisivos “shows de realidade” operam paradoxalmente, em consonância com nossas paradoxais práticas culturais.

    Full Text Available O objetivo deste artigo é estudar um caso de relocalização alimentar e formação de cadeias curtas em dado local no sul do Rio Grande do Sul, através da venda de cordeiro por pecuaristas familiares do território Alto Camaquã. Para tanto, o caso analisado envolveu uma experiência em curso da construção de mercados da pecuária familiar, em específico de produção e comercialização da carne de cordeiro. O mercado da carne de cordeiro dos pecuaristas familiares recebe destaque por consistir em uma estratégia de revalorização da procedência de origem dos alimentos, destacando a construção de cadeias curtas nas formas estratégicas elaboradas entre produtores e consumidores para o estabelecimento de relações de comercialização dos produtores, construindo, desse modo, um processo de revalorização de um lugar e de um produto. Sendo assim, a venda local por pequenos produtores representa, entre tantos significados, um comprometimento de preservação da comunidade, da tradição, de conhecimento tácitos, entre outros valores não mercantis.

    This descriptive study was carried out to assess the awareness and acceptability of Assisted Reproductive Technology (ART) among infertile women in Lagos, Nigeria. Self-administered questionnaires on the knowledge of ART in the women were used. After a brief exposé on ART, questions relating to their attitude were answered. A total of 166 women were studied. Only 51.8% had any knowledge of ART and most of these had poor knowledge. A total of 137 women would embrace ART if offered but 29 would not, for reasons such as religion, fear of side-effects, failure and unaffordable costs. There is a paucity of good knowledge of ART. A significant number of the women would consider ART if offered. There is thus a need to create more awareness about the possibilities offered by ART, as well as instituting low cost ART strategies in developing world countries.

    Lago Loíza is a reservoir formed at the confluence of Río Gurabo and Río Grande de Loíza in the municipality of Trujillo Alto in central Puerto Rico, about 10 kilometers (km) north of the town of Caguas, about 9 km northwest of Gurabo, and about 3 km south of Trujillo Alto (fig. 1). The Carraizo Dam is owned and operated by the Puerto Rico Aqueduct and Sewer Authority (PRASA), and was constructed in 1953 as a water-supply reservoir for the San Juan Metropolitan area. The dam is a concrete gravity structure that is located in a shallow valley and has a gently sloping left abutment and steep right abutment. Non-overflow sections flank the spillway section. Waterways include an intake structure for the pumping station and power plant, sluiceways, a trash sluice, and a spillway. The reservoir was built to provide a storage capacity of 26.8 million cubic meters (Mm3) of water at the maximum pool elevation of 41.14 meters (m) above mean sea level (msl) for the Sergio Cuevas Filtration Plant that serves the San Juan metropolitan area. The reservoir has a drainage area of 538 square kilometers (km2) and receives an annual mean rainfall that ranges from 1,600 to 5,000 millimeters per year (mm/yr). The principal streams that drain into Lago Loíza are the Río Grande de Loíza, Río Gurabo, and Río Cañas. Two other rivers, the Río Bairoa and Río Cagüitas, discharge into the Río Grande de Loíza just before it enters the reservoir. The combined mean annual runoff of the Río Grande de Loíza and the Río Gurabo for the 1960–2009 period of record is 323 Mm3. Flow from these streams constitutes about 89 percent of the total mean annual inflow of 364 Mm3 to the reservoir (U.S. Geological Survey, 2009). Detailed information about Lago Loíza reservoir structures, historical sediment accumulation, and a dredge conducted in 1999 are available in Soler-López and Gómez-Gómez (2005).

    Full Text Available A radiologia é uma área muito importante para as ciências biomédicas. Apesar dos benefícios que os exames radiológicos oferecem, muito têm se discutido sobre o destino dos efluentes gerados por este tipo de atividade. Os problemas ambientais ocasionados por essas substâncias são diversos: contaminação de rios, lagos e lençóis freáticos além da ausência de um tratamento adequado dos resíduos por parte dos geradores. O objetivo desta pesquisa foi realizar um diagnóstico sobre o gerenciamento dos resíduos em serviços de radiologia em três centros de saúde da Região dos Lagos estado do Rio de Janeiro. As informações foram obtidas através de entrevistas realizadas por questionário semiestruturado direcionado aos responsáveis técnicos. Foram obtidas informações sobre: o volume total de líquido produzido, a forma de armazenamento, os métodos de descarte, dentre outras. Após o tratamento dos dados, os mesmos foram confrontados com a literatura, mantendo-se a imparcialidade para o melhor conhecimento possível sobre o tema. Os dados da pesquisa revelaram uma não conformidade com a legislação e parâmetros estabelecidos pelas instituições fiscalizadoras. De uma forma mais específica, observou-se uma certa dificuldade em relação ao gerenciamento dos líquidos residuais, evidenciando a possibilidade de riscos para a saúde e meio ambiente. Uma preocupação evidenciada na pesquisa está relacionada ao destino das películas inutilizadas, observou-se pouca preocupação em relação a este tipo de descarte. Conclui-se que o diagnóstico realizado sinaliza pontos preocupantes sobre o gerenciamento dos resíduos nos serviços de radiologia. A pesquisa deixa uma contribuição para futuras discussões sobre o tema.

Pretende-se, neste texto, abordar o papel que Cabo Verde teve no Atlântico incidindo, particularmente, na dimensão cultural resultante do contacto entre povos e culturas provenientes de diferentes paragens que se fixaram no arquipélago ou que por aqui passaram. Procurar-se-á evidenciar não só a importância que Cabo Verde teve enquanto ponto de passagem obrigatória mas, sobretudo, as contribuições que mais marcadamente se denunciaram, isto é, os apports culturais que mais se acentuaram em Cabo Verde, como processos recebidos dos estrangeiros que por estas ilhas se cruzaram.The Archipelago of Cape Verde, discovered between 1460 and 1462, and situated in the Atlantic Ocean, had been considered for centuries one of the mandatory harbours of the ships that sailed across the Atlantic to the ports of America, Europe and Africa. Because of its strategic location, Cape Verdean anchorage was considered not only the supplying point, but also an important melting pot of races and cultures. It is intended to highlight the role of Cape Verde in the Atlantic focusing particularly on the cultural aspect, as a result of the influence of cultures and origins of people who had settled in or had passed by the archipelago. It is also aimed to underline the importance of Cape Verde as a mandatory gateway but, above all, to underline the remarkable contributions, such as the cultural “apports” by which Cape Verde were gripped, like processes brought by the foreigners who crossed these islands.

    Precious metal-bearing quartz veins occur at the northeastern sector of the Lago Fontana region in southwestern Argentina, within the context of the Andean continental magmatic arc environment. The deposits and their associated alteration zones are spatially related to a Cretaceous calc-alkaline magmatism represented by silicic dikes and hypabyssal intrusions, and hosted by a Late Jurassic to Cretaceous volcano-sedimentary sequence. The veins and related veinlets crop out discontinuously, in general terms in a NW-SE belt. The primary vein mineral assemblage is composed mostly of pyrite ± galena ± chalcopyrite > hematite ± arsenopyrite in silica gangue minerals. Chemical analyses of grab samples from selected quartz veins show as much as 5.7 ppm Au and 224 ppm Ag, as well as elevated Pb, Cu, and Zn. Hydrothermal fluids caused an innermost silicification and adularia-sericite alteration assemblage, and an external propylitic halo. Sulfur isotope values measured for sulfides (δSS from -1.90 to +1.56‰), and oxygen and hydrogen isotopes measured on quartz crystals and extracted primary fluid inclusion waters (δOO = -2.85 to +5.40‰; δDO = -106.0 to -103.4‰) indicate that mineralization probably formed from magmatic fluids, which were mixed with meteoric waters. Also, fluid inclusion data from quartz veins point out that these fluids had low salinity (1.7-4.2 wt% NaCl equiv.), and temperatures of homogenization between 180 and 325 °C. Mineralogical, petrographic and geochemical features for mineralized surface exposures indicate a typical adularia-sericite, low sulfidation epithermal system in the Lago Fontana area that represents a promising target for further exploration programs.

    Full Text Available Regional cluster, a geographically bounded concentration of interdependent firms, is the best environment to fostering a strong relationship amongst firms which can lead to amazing technological and industrial expansion. This paper underscores clustering and the resultant nature of relationship amongst firms, using the Lagos region as a case study. One hundred and three questionnaire were administered in twelve industrial estates; one questionnaire in each of the firm. This connotes that all the firms in the industrial estates were successfully covered in the questionnaire administration, which was administered. A descriptive statistical analytical technique was adopted. The paper has reveals the types of working relationship amongst firms in the Lagos region which includes; raw materials purchase, subcontract, collaboration in research and development, sales promotion, transportation, power supply, water supply, security, waste treatment, telecommunication, ports and shipping as well as labour supply. The paper found out that raw materials purchase/supply was more striking amongst the working relationship types. Also, the paper has revealed services sharing amongst the firms and transport as the most dominant. The most important location advantage was the market facilities. The analysis of variance carried out in relation to variation in clustering amongst the firms at 0.05% level was significant. The paper concluded that industrial cluster if encouraged, will lead to increase working relationship, which in turn have the capability of boosting, promoting and encouraging economies of clustering. Cluster concepts spatially emphasize inter-firm relations that facilitate innovative activity, which is recognized as a driving force of sustained economic growth. It is therefore recommended that these clustering of firms should be made viable, encouraged and strengthened through government investment in the industrial sector, making the location

    Contraception means procedures employed to interfere at one stage or the other with the normal sequence of events in the process of reproduction leading to a failure in conception. It means voluntary techniques adopted to achieve birth control. Its use remains sensitive worldwide. Within the same society, contraception varies amongst people of different socio-cultural, educational, religious, or occupational affiliations. It also varies between urban and rural settlements. Some contraceptive techniques also prevent sexually transmitted infections (STIs). The prevalence of STIs also varies with these same factors. There is very limited literature on contraception exclusively amongst bankers. We sought to investigate the level of awareness and practice of contraception amongst bankers in an urban society in Lagos State, Nigeria. In this descriptive cross-sectional study, 200 self-administered structured questionnaires were retrieved from bankers from 5 banks selected by simple random sampling in Surulere Local Government Area of Lagos State, Nigeria. Data was subsequently statistically analyzed using SPSS. The age range was 21-45 years, mean 28.8±1.4 years, 51.7% were males (72% single, 27% married, 1% separated) and 48.3% were females (52.4% single, 47.6% married). All (100%) respondents were aware of contraception, 93.3% males and 91.7% females were sexually active, 88.9% males and 84.5% females believe contraception is useful. Most (71.4%) respondents practice contraception, males (81%) being more than females (61.1%), p males believe that contraception prevents pregnancy but not STIs, 28.6% of females and 46.6% of males believe it prevents both pregnancy and STIs, whereas 14% of males and no female believe contraception prevents STIs but not pregnancy. The awareness of and practice of contraception was very high among the bankers but more male bankers practice contraception whereas more female bankers perceive contraceptives to be for the married only.

    Full Text Available The differences in construction methods between different forms of slabs construction tend to result into variation in the cost of the slabs for any building project. Thus, this study aims at assessing the variation in construction cost among various construction methods available for hollow and solid floors in construction projects within Lagos State. The research design for this study was a survey design approach and the population of the study are active professionals (Architects, Civil Engineers, Builders, Quantity Surveyors, Consultant and contractors because they are the major participants in the construction activities of the construction industry in Lagos State, Nigeria. The research is based on 46 returned questionnaires out of the 60 that was administered. The data from the questionnaires were analyzed using descriptive tools such as frequencies, percentage and mean values. The hypotheses were tested with paired sample t-test and it was found that the system or method of slab construction well known to the respondents is cast in situ, precast and semi-precast. The study also shows that the cost of in-situ solid slabs are higher than that of hollow slab which is an indication that solid slab construction is more expensive than hollow slab construction provided the hollow slab is a one-way hollow floor and not waffle floor. In pre cast solid slab construction the cost of transportation of units to sites, cost of expertise required in the construction process and the cost of fabrication off site are the three highest and most expensive aspects of precast solid slab while cost of erection and placement and the cost of grouting and topping if required are less expensive. Therefore there is difference in the cost of construction between the solid and hollow slabs but the difference is not appreciable. The study's major recommendation is that, adequate and careful analysis must be done in the choice of floor system being adopted for any

    Full Text Available INTRODUCTION: Toxoplasma gondii infection has been described as the most widespread zoonotic infection of humans and other animals. Information concerning T. gondii infection among schoolchildren is unavailable in Lagos City, Nigeria. METHODS: This cross-sectional study investigated the seroprevalence and risk factors associated with T. gondii infection among primary schoolchildren (PSC from a community located in the center of Lagos, southern Nigeria, from November 2013 to March 2014. A total of 382 PSC were screened for the presence of sera anti-T. gondii antibodies using a latex agglutination test (TOXO Test-MT, Tokyo, Japan. A cutoff titer of ≥ 1:32 was considered positive, while titers ≥ 1:1,024 indicated high responders. Questionnaires were also used to obtain data on possible risk factors from parents/guardians. RESULTS: The overall seroprevalence was 24% (91/382, and 83.5% (76/91 of seropositive PSC were classified as high responders. Among the risk factors tested, including contact with cats and soil, consumption of raw meat and vegetables, and drinking unboiled water, none showed statistical significance after multivariate adjustment. No associations were observed among age, gender, body mass index (BMI, and parents' occupation/educational level. CONCLUSIONS: The findings in this study show evidence of active infection, and hence, there is need for urgent preventive measures in this city. Further investigation is required to clarify the transmission routes. Policy makers also need to initiate prevention and control programs to protect pregnant women and immunocompromised patients in particular because they are more severely affected by T. gondii infection.

  11. Evaluation of Energy Use in Public Housing in Lagos, Nigeria: Prospects for Renewable Energy Sources

    Full Text Available Even though domestic energy can be from either renewable or non-renewable sources, the former is preferred because of its role in reducing both the operational energy intensity and carbon footprint. Given the positive role renewable energy plays in the energy mix, this paper examined the pattern of operational energy use with particular reference to the renewable and non-renewable energy content in medium and high density public residential buildings in Lagos, Nigeria. A survey research method was adopted for primary data collection while data analysis was by descriptive statistics. The study found that renewable energy use in the residential units is very low. In contrast, there was high dependence of the occupants on non-renewable direct fuel combustion through the use of fossil fuel-driven privately-owned electricity generators for electricity supply as a result of the inadequate supply from the national grid. In addition to the relatively high operational energy intensity observed in the studied buildings, the findings have implications for the safety, health and wellbeing of the building occupants as well as for carbon emissions from the buildings and for overall environmental sustainability. Recommendations to increase renewable energy use in new buildings and as retrofits in existing buildings were made.

    Complete and accurate pathology reporting of colorectal carcinoma (CRC) resection specimen is critical to clinical management of individual patients. The study aims to audit colorectal cancer histopathology reporting in Lagos between 2011 and 2015 before the adoption of the Society for Gastroenterology and Hepatology in Nigeria pro forma in 2016. All resected CRC cases were identified from the Histopathology record of our Department and that of a private Laboratory in Lagos over a 5-year from 2011 to 2015. The dataset as contained in the pro forma was extracted from the reports and analysed using SPSS version 16 software. A total of 92 colorectal resections were received during the 5-year period consisting of 90 colonic and 2 rectal tumours. Data inclusiveness on tumour differentiation, extent of primary tumour, total lymph node and lymph node involvement were 96.7%, 91.3%, 83.7% and 92.4%, respectively. Tumour perforation, level of venous involvement and distant metastasis were reported in 73.9%, 21.7% and 96.7% respectively. The circumferential resection margin (CRM) in the 2 rectal tumours had 100% inclusiveness. Tumour node metastasis staging was complete in 87% of cases while Dukes staging was documented in 8.7% of the reports. None of the data items was 100% complete except the CRM for rectal carcinoma. Free text reporting results in incomplete data resulting in improper staging, especially the lymph node status. This highlights the need for pro forma reporting to ensure and maintain consistent reporting of important parameters required for proper staging and management of patients with colorectal cancer.

    Science outreach and engagement are crucial core objectives of the Lagos Ciência Viva Science Centre (CCVL). By engaging audiences in the real world a link is made between their science centre experience and the environment in which they live. Therefore, it has been an option of the CCVL to offer geological outdoor activities, both in the natural environment and urban context. Dinosaurs are an appealing science subject for both students and tourists. Thus, the CCVL has a long tradition in organizing and guiding field trips to two dinosaur track sites - Salema and Santa beaches (Vila do Bispo, southwest Algarve). These sites, both from the Lower Cretaceous reveal at least two types of tracks - theropod and iguanodontian footprints. Often in combination with the paleontology field trips, the CCVL also offers different geological field trips both for formal (school) and informal (tourism) education. This allows students and tourists to be introduced to dinosaur paleobiology and ichnology and to the structural geology and stratigraphy of the area. Our science outreach is being further developed by contractual agreement with a regional tour operator, in which the CCVL is responsible for the scientific content and guidance of the visits. Aiming at an urban context, the CCVL produced three Urban Geology and Paleontology Guide Books for three Algarve cities (Lagos, Faro and Tavira), which can be acquired in the three Ciência Viva Science Centres shops as well as in the tourist information offices serving this way as a basis for guided urban tours also offered by the CCVL. Based on our experience, we review and contextualise these geoscience activities and their potential for science outreach, communication and tourism. We discuss and propose a classification of different possibilities in geoscience communication and outreach based on three vertices: Science, Heritage and Geotourism. Some particularities of these visits, such as the merge between geosciences and other

    Full Text Available Este estudo objetiva descrever a diversidade e investigar aspectos da classificação de um remanescente de floresta ripária na região de Lages, estado de Santa Catarina. Usando o método de parcelas foram alocadas vinte e cinco unidades amostrais ao longo do curso de água, sendo mensuradas todas as espécies arbóreas com diâmetro à altura do peito (DAP maior ou igual a 5 cm. A comunidade apresentou um dossel multiestratificado com espécies emergentes de grande porte e uma riqueza de 67 espécies arbóreas. A distribuição em diâmetro evidenciou uma comunidade autoregenerativa, com um grande número de indivíduos de pequenos diâmetros, os quais juntamente com as árvores de grande porte, somaram altos valores de área basal e densidade por hectare. A classificação separou os trechos mais desenvolvidos com maior área basal e complexidade com a presença de Cabralea canjerana e Myrcia hatschbachii dos trechos mais instáveis e com presença das espécies mais generalistas Celtis iguanaea e Ilex brevicuspis, denotando uma grande variabilidade ambiental nesse tipo de floresta.

    2007-12-01

    Full Text Available O objetivo do presente texto é refletir sobre como o crítico de arte se manifesta em seu texto e que papel ele exerce no campo de produção artística. Atualmente, é possível observar uma tendência do autor de crítica em assumir uma posição de “não-pessoa”, já que não usa nenhum vestígio explícito de primeira pessoa, o que denotaria que é ele mesmo o enunciador. Assim, parece revestir a sua opinião de um caráter factual e até mesmo científico, assumindo um lugar algo autoritário de “pequeno deus” característico de um discurso jornalístico fortemente influenciado pelos paradigmas positivista e crítico. A crítica musical da revista Bravo!, publicação mensal dedicada à cultura de grande circulação no Brasil, foi utilizada como amostra para ilustrar essa forma como o gênero tem se configurado.

    Full Text Available Tendo em vista o aumento do transporte marítimo no mundo e a consequente demanda por operações nos portos, os operadores buscam formas de minimizar o tempo de permanência dos navios no porto. Para atracar um navio, os portos necessitam ter disponíveis diversos recursos. Assim, planejar a designação de recursos eficientemente para não atrasar a atracação dos navios é vital para os portos. Esta designação é dinâmica, pois atrasos e antecipações na chegada dos navios ocorrem por diversos fatores demandando assim que ela seja atualizada constantemente. Este artigo propõe um Multiagent System (MAS para resolução da designação de recursos de forma distribuída e em tempo real, visando reduzir o tempo de espera para atracação dos navios. Testes foram realizados em 27 cenários e os resultados mostraram que o MAS resolveu instâncias de teste de grande porte e nos cenários mais próximos do real, ele resolveu em um tempo pequeno e com soluções estáveis.

    Full Text Available Este artigo tem por objetivo mensurar e avaliar os reflexos da Lei de Responsabilidade Fiscal (LRF sobre o espaço de manobra da gestão financeira dos pequenos municípios paranaenses com população entre 10 e 20 mil habitantes, tendo como referência as peculiaridades e atribuições dos governos locais. A fundamentação teórica compreende os conceitos relacionados à organização do setor público brasileiro, LRF, administração pública gerencial, gestão municipal e, especificamente, à gestão financeira municipal. A pesquisa é caracterizada do ponto de vista metodológico como descritiva e explicativa quanto aos objetivos; bibliográfica e documental quanto aos procedimentos; e quantitativa quanto à abordagem do problema. São analisados os municípios paranaenses com população entre 10 e 20 mil habitantes que disponibilizaram informações na base de dados Finanças do Brasil, da Secretaria do Tesouro Nacional (Finbra. A técnica estatística empregada é a regressão linear múltipla. Nas análises de regressão, foram incluídas 22 variáveis explicativas, envolvendo aspectos financeiros e de gestão dos municípios. Conclui-se que o espaço de manobra dos pequenos municípios paranaenses não foi reduzido pela LRF como era esperado e, sim, aumentado tanto em termos absolutos como em termos relativos, o que evidência significativa melhoria da gestão financeira. Além disso, as análises de regressão e as análises complementares envolvendo o coeficiente de espaço de manobra sobre as despesas correntes mostram significativa mudança estrutural como decorrência da LRF.

Em razão disso, há uma diversidade de ações realizadas com o nome de "Qualidade Total'. Uma revisão da teoria é complexa, porque existem muitos autores que tratam da questão. Eles escolhem diferentes perspectivas de análises (teóricas e empíricas e há dificuldades em se identificar um corpo conceitual. Há uma ampla difusão de modelos, ferramentas, técnicas, mercado e consultores. Essa popularidade, muitas vezes, faz com que determinadas organizações adotem essa forma de gestão do trabalho sem o conhecimento necessário das implicações que um modelo dessa ordem representa; especialmente no caso brasileiro, suscetível a proposições importadas. O presente artigo propõe um exame daquilo que os fundadores têm articulado sobre TQM, as principais críticas nesta direção e a avaliação de como vem sendo aplicadono nosso país.

    Full Text Available The need for comprehensive air pollution studies in Lagos cannot be overemphasized in view of the level of industrialization of the city and its nearness to the ocean. Air particulate samples collected with a high-volume air sampler at three locations in Lagos, Nigeria were analyzed by the combination of wavelength-dispersive X-ray fluorescence and atomic absorption spectroscopy methods. Elemental concentrations were subjected to factor analysis for source identification and chemical mass balance model was used for source apportionment. Prominent among sources identified with the ranges of their contributions at the sites are: soil 35-54%, marine 26-34%, automobile exhaust 0.3-3.5%, refuse incineration 2-3%, and regional sulphate 2-12%.

  6. Testing freshwater Lago Mare dispersal theory on the phylogeny relationships of iberian cyprinid genera Chondrostoma and Squalius (Cypriniformes, Cyprinidae

    Carmona, José Ambrosio

    2003-12-01

    Full Text Available A phylogeny of the species in the genera Chondrostoma and Squalius was constructed based on the complete mitochondrial cytochrome b gene (1140pb. The molecular phylogeny was used to test the effect of the Mediterranean Lago Mare dispersal theory on the processes of divergence and speciation of European freshwater fishes. Phylogenetic relationships among Squalius samples and the molecular clock revealed that the ancestor of the current Iberian Squalius species inhabited a wide geographic area in the central and southwestern part of the former Iberian Peninsula during the Miocene before the Lago Mare phase. Similarly, the four main Iberian lineages of the genus Chondrostoma originated in the Middle-Upper Miocene. Hence, the Lago Mare phase of the Mediterranean Sea seems to have been a too recent paleogeographic event to have had any major impact on the dispersion of Squalius and Chondrostoma species. However, the reduction of the water-bodies during the Tortonian and Messinian may have intensified the isolation of populations. The Operational Biogeographic Units recovered from the Squalius and Chondrostoma phylogenies also reject the Lago Mare dispersal theory and support the idea that the differentiation processes were due to both the formation of the current hydrographical basin during the Plio-Pleistocene as well as to an earlier endorrheism event that occurred prior to hydrographical configuration.Realizamos una filogenia de los géneros Chondrostoma y Squalius mediante el estudio de la secuencia completa del gen mitocondrial citocromo b (1140pb. La filogenia molecular fue usada para comprobar el efecto que la teoría de dispersión del Mediterráneo Lago Mare ha tenido sobre los procesos de divergencia y especiación en los peces de agua dulce europeos. Las relaciones filogenéticas entre las muestras de Squalius y la aplicación del reloj molecular pusieron de manifiesto que el ancestro de las actuales especies ibéricas de Squalius habitaba

    We evaluated the spatial and temporal variation in communities of dragonfly's naiads and their association to the habitat rehabilitation status in La Vaca and Santa Maria del Lago wetlands. Four samplings were carried out in several sites of each during a year. Macroinvertebrates were collected at the entry and exit flow, and in open waters of the wetlands using standard techniques. We found a gradient in the distribution of the abundance of nymphs in both wetlands, where naiads community had the highest number of individuals in the places located farther from the dumping sites. Comparing the community s composition between wetlands La Vaca and Santa Maria del Lago through the beta diversity, heterogeneity was found in both ecosystems. The gradient in the distribution of the abundance of naiads observed in both wetlands fits with to a response of the species in terms of tolerance to the environmental variables.

    Full Text Available Este estudo representa a primeira avaliação da maturação nuclear de oócitos por análise citogenética realizada em duas espécies de felídeos brasileiros ameaçados de extinção: L. pardalis (n=5 e L. tigrinus (n=4. Os animais foram submetidos à estimulação ovariana alternada com eCG-hCG e pFSH-pLH a cada quatro meses pelo período de dois anos, perfazendo um total de 6 intervenções. Os oócitos foram recuperados por vídeo-laparoscopia, caracterizados quanto à morfologia e utilizados para determinação dos estágios do ciclo meiótico por análise citogenética e maturação pela caracterização de metáfase II. Dos 33 oócitos de jaguatirica avaliados 12% (n=4 apresentaram cromossomos condensados em seu interior e dos 11 oócitos de gato-do-mato-pequeno avaliados 36% (n=4 apresentaram cromossomos condensados em seu interior, no entanto, nenhum oócito encontrava-se em metáfase II. Avaliação morfológica dos oócitos mostrou as mesmas características encontradas em outros mamíferos. Comparando os tratamentos, não houve diferença significativa (p>;0,05 no número total de estruturas ovarianas (folículos e corpos lúteos recentes observadas em estimulações alternadas sucessivas, nas duas espécies estudadas. Também não houve diferença significativa em relação ao total de estruturas ovarianas encontradas em cada tratamento (5,7±1,2 eCG/hCG; 7,9±0,9 pFSH/pLH para L. pardalis e (2,6±0,7 eCG/hCG; 2,0±0,5 pFSH/pLH para L. tigrinus. Apesar das limitações deste experimento e do número reduzido de oócitos avaliados podemos sugerir que a aspiração folicular após estimulação ovariana com eCG/hCG e pFSH/pLH alternadamente resulta na recuperação de oócitos imaturos, que necessitam de cultivo em meios específicos para atingir o estágio de Metáfase II.

    Full Text Available Esse trabalho investiga um problema combinado de planejamento da produção e corte de estoque comum em fábricas de móveis de pequeno porte, onde os custos de produção envolvidos no processo de manufatura e as demandas dos produtos não são conhecidos com precisão. Para lidar com essas incertezas, foram propostos modelos de otimização robusta que permitem controlar o conservadorismo da solução de acordo com a atitude do decisor em relação ao risco. Experimentos computacionais baseados em dados reais de uma planta moveleira mostraram que é possível obter soluções robustas sem sacrificar em demasia o custo total. Além disso, observou-se que estratégias tipicamente utilizadas na prática para lidar com as incertezas podem gerar planos de produção com custos totais proibitivos.This paper investigates an integrated production planning and cutting stock problem that is common in small-scale furniture plants, in which the production costs involved in the manufacturing process and the demands for the products are not known precisely. To deal with these uncertainties, robust optimization models that control the conservatism of the solution according to the attitude of the decision maker towards risk were proposed. Computational experiments based on real data from a furniture plant showed that it is possible to obtain robust solutions without overly sacrificing the total cost. In addition, it was observed that commonly used strategies to deal with uncertainty issues can result in production plans with prohibitive total costs.

    Several toxicological studies into the effects of aquatic pollutants on the liver of teleost fish exist in literature. The focus on the liver in these studies is predicated on its central nature in the scheme of biotransformation and excretion of xenobiotics following exposure in polluted water bodies. As a consequence of the latter primary role of the liver in these processes it is regarded as a predilective site for the sub lethal effects of xenobiotics on the organism usually detectable at histological level. Hepatic histopathology recorded in livers from feral populations of the brackish water catfish Chrysichthys nigrodigitatus from locations on the Lagos lagoon complex with significant anthropogenic inputs from denizen populations and industries are presented. Liver sections from sixty specimens from two locations on the Lagos lagoon complex (Badagry lagoon: 6??24'N, 2??56'E; and Lagos lagoon: 6??29'N, 3??22'E) were analysed. Observed pathologies included hydropic degeneration (58%), portal / sinusoidal congestion (33%), hepatic necrosis (26%), hemosiderosis (12%) and foci of cellular alterations (FCA's). No obvious oncologic features were observed; the presence of the hydropic Vacuolation lesion was taken as prelude to the development of neoplasms and discussed as such. ?? 2009, Penkala Bt., Budapest, Hungary.

    Full Text Available Studies have shown that the quality of outcome in Nigerian secondary schools is declining at an alarming rate due to shortage of required resources as well as leadership challenges. The challenges have been observed to be as a result of lack of mentoring which is not a common practice in school management in Nigeria. Consequently, this study investigated the extent to which mentoring as a strategy for administrators' succession plan impacts on the performance of their duties in public and private secondary schools in Lagos, Nigeria. The study adopted the descriptive survey design and administered a 25-item self-constructed questionnaire on participants. A total of 530 participants were randomly selected from the population of 4,350 senior teachers. The Participants were drawn from 145 secondary schools (91 public and 54 registered private in Education District IV of Lagos State. The findings showed that mentoring has significant impact on administrators' succession planning and that succession planning does not significantly differ in public and private secondary schools in Lagos State. The study concluded that leadership development is a critical factor in secondary school effectiveness and efficiency. Therefore, serving administrators as well as prospective administrators should be regularly evaluated to determine their training needs at different career stages. There should also be mentoring related policies to enhance the managerial skills, sense of competence and effectiveness of the prospective administrators.

O enfermeiro é o que mais desenvolve a função gerencial, porém, informalmente. O modelo gerencial verticalizado e autoritário predomina, e há fragilidade no exercício frente à autonomia e ao corporativismo de profissionais. Na dimensão política, interesses político-partidários sobrepõem-se às decisões gerenciais; e, na dimensão relacional, há manifestação de conflito, com desrespeito e disputas, mas, também, colaboração, com diálogo e trabalho em equipe. Nesses municípios, os processos gerenciais são pouco desenvolvidos, necessitando de profissionalização e oficialização do cargo, além do desenvolvimento de educação permanente.

    This paper presents a study on the passive residual heat removal system (PRHRS) of a small modular nuclear reactor (SMR) of 75MW. More advanced nuclear reactors, such as generation III + and IV, have passive safety systems that automatically go into action in order to prevent accidents. The purpose of the PRHRS is to transfer the decay heat from the reactor's nuclear fuel, keeping the core cooled after the plant has shut down. It starts operating in the event of fall of power supply to the nuclear station, or in the event of an unavailability of the steam generator water supply system. Removal of decay heat from the core of the reactor is accomplished by the flow of the primary refrigerant by natural circulation through heat exchangers located in a pool filled with water located above the core. The natural circulation is caused by the density gradient between the reactor core and the pool. A thermal and comparative analysis of the PRHRS was performed consisting of the resolution of the mass conservation equations, amount of movement and energy and using incompressible fluid approximations with the Boussinesq approximation. Calculations were performed with the aid of Mathematica software. A design of the heat exchanger and the cooling water tank was done so that the core of the reactor remained cooled for 72 hours using only the PRHRS.

    This work presents an analysis of the reliability of the emergency power supply system, of a small size nuclear power reactor. Three different configurations are investigated and their reliability analyzed. The fault tree method is used as the main tool of analysis. The work includes a bibliographic review of emergency diesel generator reliability and a discussion of the design requirements applicable to emergency electrical systems. The influence of common cause failure influences is considered using the beta factor model. The operator action is considered using human failure probabilities. A parametric analysis shows the strong dependence between the reactor safety and the loss of offsite electric power supply. It is also shown that common cause failures can be a major contributor to the system reliability. (author)

    Preterm birth is a dire complication of pregnancy that poses huge long-term medical and financial burdens for affected children, their families, and the health care system. The aim of the present study was to identify characteristics associated with preterm births at the Lagos University Teaching Hospital (LUTH), Lagos, Nigeria from 2011 to 2013. We obtained Information from 5,561 maternal, fetal/neonatal and obstetric records from the labor ward. We excluded delivery at less than 22 weeks (0.25%), post-term birth at ≥42 weeks gestation (1.3%), and unknown gestation (1.4%). Additionally, we excluded records of multiple births (5.4%) and stillbirths (8.3%) leaving 4,691 records of singleton live-births for analysis. Logistic regression analysis was performed comparing preterm birth (22-36 weeks gestation) to term birth (37-41 weeks gestation). Multiple variable models adjusting for maternal age, parity, fetal position, delivery method and booking status were also evaluated. Multinomial regression was used to identify characteristics associated with preterm birth (PTB) defined as early PTB (22-31 weeks gestation), moderate PTB (32-34 weeks gestation), late PTB (35-36 weeks gestation), compared to term birth (37-41 completed weeks gestation). From our data, 16.8% of the singleton live-birth deliveries were preterm (PTBs. Older maternal age (≥35 years) [odds ratio (OR) = 1.41], hypertension (OR = 3.44) and rupture of membranes (OR = 4.03) were significantly associated with increased odds of PTB. Women being treated for the prevention of mother-to-child transmission of HIV were at a significantly decreased risk for PTB (OR = 0.70). Sixteen percent of women in this cohort were not registered for antenatal care in LUTH. These non-registered subjects had significantly greater odds of all categories of PTB, including early (odds ratio (OR) = 20.8), moderate (OR = 8.68), and late (OR = 2.15). PTB and risks for PTB remain high in Nigeria. We recommend that any high risk

    During more than a decade Gamma Ray Bursts (GRB a cosmological phenomena of tremendous power) have been extensively studied in the keV - MeV energy range. However, the higher energy emission still remains a mystery. The Large Aperture GRB Observatory (L.A.G.O.) is an international collaboration started in 2005 aiming at a better understanding of the GRB by studying their emission at high energies (> 1 GeV), where the fluxes are low and measurements by satellites are difficult. This is done using the Single Particle Technique, by means of ground-based Water Cherenkov Detectors (WCD) at sites of high altitude. At those altitudes it is possible to detect air showers produced by high energy photons from the GRB, i. e. a higher rate of events on a short time scale, of the order of the second. The Pierre Auger Observatory could detect such GRB given its large number of detectors, but at 1400 m.a.s.l. the expected signal is quite small. At higher altitudes, similar performance is expected with only a very small number of WCD. As of 2011, high altitude WCD are in operation at Sierra Negra (Mexico, 4650 m.a.s.l.), Chacaltaya (Bolivia, 5200 m.a.s.l.), Maracapomacocha (Peru, 4200 m.a.s.l.), and new WCDs are being installed in Venezuela (Pico Espejo, 4750 m.a.s.l.), Argentina, Brazil, Chile, Colombia and Guatemala. Most of the new WCDs will not be at high enough altitude to detect GRB, never the less it will allow obtaining valuable measurements of secondaries at ground level, which are relevant for solar physics. The LAGO sensitivity to GRB is determined from simulations (under a sudden increase of 1 GeV - 1 TeV photons from a GRB) of the gamma initiated particle shower in the atmosphere and the WCD response to secondaries. We report on WDC calibration and operation at high altitude, GRB detectability, background rates, search for bursts in several months of preliminary data, as well as search for signals at ground level when satellite burst is reported, all these show the

    Full Text Available BACKGROUND: Microsporidia are obligate intracellular parasites that infect a broad range of vertebrates and invertebrates. They have been increasingly recognized as human pathogens in AIDS patients, mainly associated with a life-threatening chronic diarrhea and systemic disease. However, to date the global epidemiology of human microsporidiosis is poorly understood, and recent data suggest that the incidence of these pathogens is much higher than previously reported and may represent a neglected etiological agent of more common diseases indeed in immunocompetent individuals. To contribute to the knowledge of microsporidia molecular epidemiology in HIV-positive patients in Nigeria, the authors tested stool samples proceeding from patients with and without diarrhea. METHODOLOGY/PRINCIPAL FINDINGS: Stool samples from 193 HIV-positive patients with and without diarrhea (67 and 126 respectively from Lagos (Nigeria were investigated for the presence of microsporidia and Cryptosporidium using Weber's Chromotrope-based stain, Kinyoun stain, IFAT and PCR. The Weber stain showed 45 fecal samples (23.3% with characteristic microsporidia spores, and a significant association of microsporidia with diarrhea was observed (O.R. = 18.2; CI: 95%. A similar result was obtained using Kinyoun stain, showing 44 (31,8% positive samples with structures morphologically compatible with Cryptosporidium sp, 14 (31.8% of them with infection mixed with microsporidia. The characterization of microsporidia species by IFAT and PCR allowed identification of Enterocytozoon bieneusi, Encephalitozoon intestinalis and E. cuniculi in 5, 2 and 1 samples respectively. The partial sequencing of the ITS region of the rRNA genes showed that the three isolates of E.bieneusi studied are included in Group I, one of which bears the genotype B. CONCLUSIONS/SIGNIFICANCE: To our knowledge, this is the first report of microsporidia characterization in fecal samples from HIV-positive patients from

    A major share of the hospital budget is spent on drugs. Irrational use of these drugs is a waste of financial and human resources that could have been deployed for another use within the hospital setting especially in cases where such drugs are provided free to patients. Also there is increased morbidity and progression of severity with irrational use. The objective of this study was to determine the irrational use of chloroquine and the subsequent cost implications in Lagos State general hospitals. A retrospective study period of one year (January to December, 2000) was selected. A total of 18,781 prescription forms of "Free Eko Malaria" were sampled for children and adults from all the Lagos State general hospitals. Drug costs in each prescription form were identified. Cost effectiveness analysis of chloroquine tablet and intramuscular injection was undertaken. The average cost of medicine per prescription was 132.071 ($1.03) which should have been 94.22 ($0.73) if prescribed rationally. The total cost of prescriptions for malaria under study was 2,480,425.00 ($19,348.09). About 68% {(1,679,444.00) ($13,100.19)} of the total cost was lost to irrational prescribing. This is a waste of scarce resources. When the prescriptions were differentiated into the different dosage forms prescribed, the prescriptions containing intramuscular injections only had over 90% of the cost lost to irrational prescribing. Cost effectiveness analysis showed that chloroquine tablet was 17 times more cost effective than chloroquine injection (intramuscular) from a health care system perspective while it was 14 times more cost effective from a patient perspective. There is waste of scarce resources with irrational dispensing of drugs and these resources could have been deployed to other uses or areas within the hospitals. The tablet chloroquine was more cost effective than injection chloroquine (intramuscular). Increasing the cost of tablets, decreasing effectiveness of tablets

    The global system mobile telecommunications system (GSM) which was recently introduced in Nigeria is now being used by over 40 million people in Nigeria. The use of GSM is accompanied with exposure of the users to radiofrequency radiation (RFR), which if significant, may produce health hazards. This is the reason why many relevant national and international organizations recommended exposure limits to RFR and why it is made compulsory for GSM handsets to indicate the maximum power output as a guide to potential consumers. This study was conducted to measure the RFR output power densities (S) from the most commonly used GSM handsets used in Lagos State and compare with the limit recommended for safety assessment. Over 1100 most commonly used handsets of different makes and models as well as wireless phones were sampled and studied in all over the local government areas of the State. An RFR meter, Electrosmog from LESSEMF USA was used for the measurements. The handsets were assessed for health risks using the reference value of 9 Wm(-2) as recommended by the International Commission on Non-Ionizing Radiation Protection (ICNIRP). The range of the S-values obtained varied from a minimum of 1.294 0.101 Wm(-2) with Siemens model R228 to a maximum of 16.813 +/- 0.094 Wm(-2) with Samsung model C140*. The results from wireless telephones showed very low S-values ranging from a minimum of 0.024 +/- 0.001 Wm(-2) with HUAWEI and ST CDMA 1 to a maximum of 0.093 +/- 0.002 Wm(-2) with HISENSE. The results showed that the population in Lagos State may be at risk due to significant RFR exposures resulting principally from the use of GSM. Quite a number of handsets emit power above the ICNIRP recommended value. Measured RFR power close to Radio and Television masts and transmitters are within tolerable limits in most cases, only that the public should not reside or work close to RFR installations. Phone calls with GSM should be restricted to essential ones while youths and children

    Full Text Available Compared to its alternatives, the claims that democracies result from the material-economical modernisation, the incarnation of a certain type of political culture or the institutional objectivation seem to be less and less reasonable. The aim of this article is not only to familiarise the reader with one of the most promising theoretical perspectives of contemporary comparative historical sociology – that of Charles Tilly – but also to demonstrate how a processual analysis of political regimes is the more suitable to understand and improve today’s real democracies.

    We investigated food hygiene-related behaviour as well as other risk factors for diarrhoea in children 6-36 months of age in Iwaya community in Lagos, Nigeria. Between April and July 1989, a bi-weekly diarrhoea surveillance was maintained in 672 households. Following the surveillance, 273 (case = 67 and control = 206) families were visited twice, each visit lasting for 3-4 hours. Detailed observations on food hygiene, water sanitation, and sanitary conditions of the home were made. There was no significant association between any of the observed food hygiene behaviours and the occurrence of diarrhoea. The presence of faeces in and around the toilet area (RR = 1.79), habit of defecating and urinating in chamber pots in dwelling units (RR = 1.80), indiscriminate disposal of waste (RR = 2.48), and source of domestic water (RR = 2.94) were the main factors significantly associated with the occurrence of diarrhoea in this community. These findings imply that diarrhoea might be reduced through an education programme which focuses on the proper care, handling and storage of defecation pots and proper disposal of waste.

  16. Mechanisms of hypolimnion erosion in a deep lake (Lago Maggiore, N. Italy

    2010-02-01

    Full Text Available Holo-oligomixis is one of the most important hydrodynamic characteristics of deep lakes in temperate regions, especially those of the Southern Alps. It influences such important lake chemical and biological processes as the oxygenation of deep layers, recycling of nutrients, vertical migration of plankton, and reproduction. Analysis of physico-chemical data from Lago Maggiore over the years 1951 – 2008 has shown that in addition to ever active but relatively inefficient convective mixing, three other mechanisms act to oxygenate this lake’s deep waters in winter. These are conveyor belt currents, cold and well-oxygenated tributary inflows that sink down to depths of equal density, and differential cooling of littoral waters that subsequently slide down the lake flanks. Their common outcome is to cause deep erosion of the hypolimnion. Heat content and thermal stability also are affected and are analyzed here in relation to external driving forces, examining in particular how dynamics may be altered by climate change.

    We studied 116 patients who presented with cleft lip and palate (CLP) and were seen during a state-wide screening exercise for people with orofacial deformities in Ikeja-Lagos, Nigeria between May 2006 and July 2007. Detailed histories were taken and physical examinations made. The following psychometric instruments: General Health Questionnaire 28 (GHQ28), State-Trait Anxiety Inventory Y1 (STAI-Y1), STAI-Y2, and Self rating Depression Scale (SDS) were given on the respondents by a clinical psychologist. The respondents comprised 57 men and 59 women with a male:female ratio of 1:1.04. There were 42 (36%) adults and 74 (64%) children. Fifty-four (47%) patients had cleft lip (CL), 27 (23%) had cleft lip and palate (CLP), and 35 (30%) had cleft palate alone. Forty-five (39%) of the respondents were parents and guardians who responded to the presence of the deformity on behalf of children who were less than 6 years old, and assessed the reactions of those who were aged 6-12 years old. Older patients replied directly to the psychometric instruments. The outcome of the assessment of the Mental Health Profile of the participants showed high incidence of anxiety, depression, and impairment of general wellbeing. The effects were most pronounced in the 6-12 year age group. We recommend that the psychosocial impacts of CLP on the patients, parents, and relations should be managed together with the reconstructive procedures.

    Service quality assessments have assumed increasing importance in the last two decades. They are useful in identifying gaps in services been provided with the ultimate aim of guaranteeing quality assurance. The objective of this study was to assess the client perception of service quality at the outpatient clinics of Randle General hospital, Lagos. A descriptive cross sectional study was conducted from March to May 2013. A multistage sampling technique was used to select respondents and data was collected with the aid of modified SERVQUAL questionnaires. The data was analysed with aid of EPI-INFO 2002 and statistical significance was set at a P value 0.05 for statistical significance. Total of 400 respondents were interviewed. The mean age was 40 years with a standard deviation of 15.2 yrs. The highest mean score of 4.35 out of a possible maximum of 5 was recorded in assurance domain while the lowest mean score of 4.00 was recorded in the responsiveness domain. The overall mean score of all the domains was 4.20 with standard deviation of 0.51. Overall majority (80.8%) of respondents rated the overall service quality as good/ very good. After linear regression, the assurance domain was the most important predictor of the overall perceived service quality (pservice quality was good. The major deficiencies were in the responsiveness domain and especially the waiting time. The hospital management should implement measures to improve the responsiveness of services by ensuring prompt delivery of services.

    Ground water from Regiao dos Lagos, a coastal area of Rio de Janeiro state, was analysed for 226 Ra, 228 Ra, 222 Rn, 238 U, major ion concentrations, and physico-chemical parameters were also measured. Concentrations values ranged from -1 for 226 Ra, from -1 for 228 Ra and from -4 to 8.0x10 -2 Bq l -1 for 238 U. Detectable 222 Rn concentrations (>3 Bq l -1 ) were found only in two samples. The spatial distribution of Ra concentration delineated one distinct area and some hot spots with high Ra concentration. Low pH value is the most important water parameter linked to high radium concentration. This is probably related to limited adsorption of radium on soil ferric oxides and hydroxides at low pH range. There was a significant correlation between uranium concentrations and electrical conductivity values, and also between uranium concentrations and concentrations of Ca, Mg, Na, K, and Cl, indicating sea water impact. Uranium concentrations were lower than maximum contaminant level for drinking water, whereas 17 out of the 88 ground water samples had levels of radium that exceeded the maximum contaminant level for tap water. The total annual effective dose for adult due to the water consumption reaches values up to 0.8 mSv

    The manufacture of paint involves a variety of processes that present with medical hazards. Safety initiatives are hence introduced to limit hazard exposures and promote workplace safety. This aim of this study is to assess the use of available control measures/initiatives in selected paint factories in Lagos West Senatorial District, Nigeria. A total of 400 randomly selected paint factory workers were involved in the study. A well-structured World Health Organization standard questionnaire was designed and distributed to the workers to elicit information on awareness to occupational hazards, use of personal protective devices, and commonly experienced adverse symptoms. Urine samples were obtained from 50 workers randomly selected from these 400 participants, and the concentrations of the heavy metals (lead, cadmium, arsenic, and chromium) were determined using atomic absorption spectroscopy. The results show that 72.5% of the respondents are aware of the hazards associated with their jobs; 30% have had formal training on hazards and safety measures; 40% do not use personal protective devices, and 90% of the respondents reported symptoms relating to hazard exposure. There was a statistically significant (p metal concentrations in the urine samples obtained from paint factory workers as compared with nonfactory workers. The need to develop effective frameworks that will initiate the integration and ensure implementation of safety regulations in paint factories is evident. Where these exist, there is a need to promote adherence to these practice guidelines.

    Road traffic injuries have persisted as a serious public health problem and much of the health burden is in developing countries. Over-speeding, poor enforcement of traffic regulations and commuter buses have been highly implicated in road traffic injuries in developing countries. The aim of this study was to determine drivers' knowledge of selected road safety measures, i.e. the pre-requisites for driver's license, road signs and speed limits. This was a cross-sectional study carried out in Lagos, Nigeria. Simple random sampling was used to select the two motor parks used for the study and all the consenting commercial minibus drivers operating within the parks (407) were included in the study. Data was collected with a pre-tested, structured, interviewer-administered questionnaire and analyzed with epi-info statistical software. Two hundred and sixty-one (64.1%) of them knew that Visual Acuity test should be done before obtaining driver's license and 53.8% knew the correct minimum age for obtaining driver's license. Only 1% of the drivers had correct knowledge of the driver's license authorities in Nigeria. The drivers had poor knowledge of road signs (59.0%) and poor knowledge of maximum speed limits (100%). The oldest, least educated and least experienced drivers had the poorest level of knowledge. The drivers demonstrated poor knowledge of road safety measures. There is need for driver education to improve their knowledge.

    Emergency contraception can play an important role in reducing the rate of unintended pregnancies in Nigeria. Although it is included in the national family planning guidelines, there is limited awareness of this method among clients. In 2003-2004, a sample of 256 health care providers within Lagos State were surveyed about their knowledge of, attitudes toward and provision of emergency contraceptives, using a 25-item, self-administered questionnaire. Frequencies were calculated for the various measures, and chi-square tests were used to determine significant differences. Nine in 10 providers had heard of emergency contraception, but many lacked specific knowledge about the method. Only half of them knew the correct time frame for effective use of emergency contraceptive pills, and three-fourths knew that the pills prevent pregnancy; more than a third incorrectly believed that they may act as an abortifacient. Fewer than a third of respondents who had heard of the pills knew that they are legal in Nigeria. Of those who had heard about emergency contraception, 58% had provided clients with emergency contraceptive pills, yet only 10% of these providers could correctly identify the drug, dose and timing of the first pill in the regimen. Furthermore, fewer than one in 10 of those who knew of emergency contraception said they always provided information to clients, whereas a fourth said they never did so. Nigerian health care providers urgently need education about emergency contraception; training programs should target the types of providers who are less knowledgeable about the method.

    Waste characterization is the first step to any successful waste management policy. In this paper, the characterization and the trend of solid waste generated in University of Lagos, Nigeria was carried out using ASTM D5231-92 and Resource Conservation Reservation Authority RCRA Waste Sampling Draft Technical Guidance methods. The recyclable potential of the waste is very high constituting about 75% of the total waste generated. The estimated average daily solid waste generation in Unilag Akoka campus was estimated to be 32.2tons. The solid waste characterization was found to be: polythene bags 24% (7.73tons/day), paper 15% (4.83tons/day), organic matters 15%, (4.83tons/day), plastic 9% (2.90tons/day), inert materials 8% (2.58tons/day), sanitary 7% (2.25tons/day), textile 7% (2.25tons/day), others 6% (1.93tons/day), leather 4% (1.29tons/day) metals 3% (0.97tons/day), glass 2% (0.64tons/day) and e-waste 0% (0.0tons/day). The volume and distribution of polythene bags generated on campus had a positive significant statistical correlation with the distribution of commercial and academic structures on campus. Waste management options to optimize reuse, recycling and reduce waste generation were discussed. Copyright © 2017 Elsevier Ltd. All rights reserved.

  4. The effects of Hurricane Hugo on suspended-sediment loads, Lago Loiza Basin, Puerto Rico

    Gellis, A.

    1993-01-01

    In the two main tributaries that enter Lago Loiza, Rio Grande de Loiza and Rio Gurabo, 99 600 tonnes of suspended sediment was transported by 58.2??106 m3 of runoff in a 48 h period. The storm-average suspended-sediment concentration in the Rio Grande de Loiza for Hurricane Hugo was 2290 mgl-1, the second lowest for the 12 storms that have been monitored at this site. In Rio Gurabo the storm-average suspended-sediment concentration was 1420 mg l -1, the sixth lowest recorded out of 15 monitored storms. In Quebrada Salvatierra, a small tributary to Rio Grande de Loiza, suspended-sediment concentrations were as low as 33 mg l-1 during peak runoff of 20m3s-1. Normally the suspended-sediment concentrations at this discharge are 300 mg l-1. Hurricane force winds seem to be the most important factor contributing to the lower than expected suspended-sediment loads. High winds caused vegetation and debris to be dislodged and displaced. Debris accumulated on hillslopes and in small channels, blocked bridges and formed debris dams. These dams caused local backwater effects that reduced stream velocities and decreased suspended-sediment loads. -from Author

    Full Text Available We present a method that utilizes multichannel analysis of surface waves (MASW, which was used to measure shear wave velocities, with a view to establishing the probable causes of road failure, subsidence and weakening of structures in some local government areas in Lagos, Nigeria. MASW data were acquired using a 24-channel seismograph. The acquired data were processed and transformed into a two-dimensional (2-D structure reflective of the depth and surface wave velocity distribution within a depth of 0–15 m beneath the surface using SURFSEIS software. The shear wave velocity data were compared with other geophysical/ borehole data that were acquired along the same profile. The comparison and correlation illustrate the accuracy and consistency of MASW-derived shear wave velocity profiles. Rigidity modulus and N-value were also generated. The study showed that the low velocity/ very low velocity data are reflective of organic clay/ peat materials and thus likely responsible for the failure, subsidence and weakening of structures within the study areas.

    The study was conducted in response to the lack of epidemiological data in recent time on the use of psychoactive substances by adolescents in metropolitan Lagos-a city unique for its socio-economic profile. We considered some methodological issues omitted in several previous studies. A total of 4,286 school pupils (mean age 15.2) were anonymously administered a Self-Report Questionnaire to ascertain a range of key drug use factors in lifetime and 1-year periods. The rate of use of most of the 14 substances investigated was much higher than reported in any other study on comparable population sample. We found that 61.8 and 32.1% of respondents have used one or more substances in their lifetime and in the past 1 year, respectively. High lifetime rates of use were found for common stimulants: coffee, kolanut, and prescription drugs (barbiturates and minor tranquilisers). The rate of use of proscribed addictive substances, cannabis, heroin, and cocaine, ranged between 4.0 and 4.8%. Missing data and non-response rates were few; however, social acquiescence, under and over reporting, could be mitigant to estimation of rates and patterns of use. We advocate properly articulated school-based educative programmes that can facilitate drug demand reduction.

    Background. ABO hemolytic disease of the newborn is the most common hemolytic consequence of maternofetal blood group incompatibility restricted mostly to non-group-O babies of group O mothers with immune anti-A or anti-B antibodies. Aim. We estimated the risk of ABO HDN with view to determining need for routine screening for ABO incompatibility between mother and fetus. Materials and Methods. Prevalence of ABO blood group phenotypes in blood donors at the donor clinic of the Lagos University Teaching Hospital and arithmetic methods were used to determine population prevalence of ABO genes. We then estimated proportion of pregnancies of group O mothers carrying a non-group-O baby and the risk that maternofetal ABO incompatibility will cause clinical ABO HDN. Results. Blood from 9138 donors was ABO typed. 54.3%, 23%, 19.4%, and 3.3% were blood groups O, A, B, and AB, respectively. Calculated gene frequencies were 0.1416, 0.1209, and 0.7375 for A, B, and O genes, respectively. It was estimated that 14.3% of deliveries will result in a blood group O woman giving birth to a child who is non-group-O. Approximately 4.3% of deliveries are likely to suffer ABO HDN with 2.7% prone to suffer from moderately severe to severe hemolysis. PMID:26491605

    Correlations for the city of Lagos (latitude 6.58 deg. N, longitude 3.33 deg. E) have been found between the records of bright sunshine hours and the daily and monthly components of the total hemispherical solar radiation. Four new models have been developed which include H/H 0 as a predictor in the Angstrom type models for the diffuse and beam fractions. They contain the quadratic term of the sunshine index, (n/N) and are given as follows: Q/H 0 =a+b(H/H 0 )+c(n/N)+d(n/N) 2 Q/H 0 =a+b(H/H 0 )+d(n/N) 2 ; Q/H 0 =a+b(H/H 0 )+c(n/N)+d(n/N) 2 ; Q/H 0 =a+b(H/H 0 )+d(n/N) 2 ; where Q is the diffuse or beam radiation on a horizontal plane. The statistical test carried out showed that the new equations generally improved the prediction of the beam or diffuse components from the Angstrom type equations by over 25%.

    Full Text Available Ebolaviruses (EBOV (family Filoviridae cause viral hemorrhagic fevers in humans and non-human primates when they spill over from their wildlife reservoir hosts with case fatality rates of up to 90%. Fruit bats may act as reservoirs of the Filoviridae. The migratory fruit bat, Eidolon helvum, is common across sub-Saharan Africa and lives in large colonies, often situated in cities. We screened sera from 262 E. helvum using indirect fluorescent tests for antibodies against EBOV subtype Zaire. We detected a seropositive bat from Accra, Ghana, and confirmed this using western blot analysis. The bat was also seropositive for Lagos bat virus, a Lyssavirus, by virus neutralization test. The bat was fitted with a radio transmitter and was last detected in Accra 13 months after release post-sampling, demonstrating long-term survival. Antibodies to filoviruses have not been previously demonstrated in E. helvum. Radio-telemetry data demonstrates long-term survival of an individual bat following exposure to viruses of families that can be highly pathogenic to other mammal species. Because E. helvum typically lives in large urban colonies and is a source of bushmeat in some regions, further studies should determine if this species forms a reservoir for EBOV from which spillover infections into the human population may occur.

The presence of the virulence-associated tdh (thermostable direct haemolysin, trh1 (thermostable-related haemolysin and trh2 genes in the V. parahaemolyticus isolates was also detected by the PCR method. PCR products from the V.16S primers were sequenced. Antibiotics susceptibility of the isolates was also determined. About, eight isolates were presumptively identified as V. parahaemolyticus, PCR identified five and none of the isolates were positive for the genes tdh or trh. The five isolates sequenced were identified as different strains of V. parahaemolyticus. V. parahaemolyticus_RIMD_2210633 = 2MKSHa remained resistant to all antimicrobials tested. However, only V. parahaemolyticus_MP-2_AY911391 = TBSHy showed strong sensitivity to all the antimicrobials with ampicillin (minimum inhibitory concentration-4 μg/ml. In addition, the other three isolates showed sensitivity for Tetracycline, Ciprofloxacin, Gentamicin and Ceftazidime. Ampicillin resistance in most of the isolates suggests low efficiency of ampicillin in management of V. parahaemolyticus infection.

    Full Text Available Em O lago da lua, Paula Tavares, escritora angolana radicada em Portugal, amalgama corpo e poesia, resultando num trabalho delicado, pulsante e, por vezes, agressivo, em que o feminino comparece na linguagem da memória, nomeando o mundo de dentro e de fora, misturando o universo africano com o europeu. O embaralhamento das tradições revela o sensível e o cognoscível, bem cosidos num texto poético particular, cujas imagens conduzem o leitor para o tempo contemplativo da arte – no caso a poesia – mas também para o tempo investigativo e analítico da razão, em suas insuspeitas relações. O propósito aqui é apresentar uma breve leitura deste livro da autora, enfatizando a relação poesia e erotismo como agregadora de valores estéticos.

    Full Text Available Three wood decomposing bacteria isolated from the Lagos lagoon, Bacillus megaterium, Bacillus bataviensis and Paenibacillus sp. were screened for their pectinase producing abilities using pectin as substrate under submerged fermentation (SMF conditions. The results showed that all three isolates produced appreciable pectinolytic activities. Paenibacillus sp. showed the highest pectinase activity when compared with the other two isolates. The optimum pH for pectinase activity for both B. megaterium and B. bataviensis was 8.0 while it was 6.5 for Paenibacillus sp., B. bataviensis, and B. megaterium showed optimum pectinase activity at 60°C and Paenibacillus sp. at 40°C. Metal ions such as Na+ and K+ improved the activity of pectinase produced by the three isolates when compared to the effect of Zn2+ and Mn2+. The molecular weights of the enzymes were also estimated by gel filtration as 29,512 da, 32,359 da, and 25,119 da for Paenibacillus sp., B. megaterium and B. bataviensis respectively. The study has provided a platform for further investigation into the biochemical characterization of the enzyme, and optimization of culture conditions to scale up pectinase production for commercial exploitation.

    Full Text Available The current upsurge of unemployment in Nigeria can be downplayed by entrepreneurship, an economic driver which reflects negatively on the adopted mono-economy of Nigeria with her dependence on oil rather than attaining a multi-diversification in all sectors. The informal entrepreneurship has proved its stance positively in curbing the unemployment issues in all sector and yet there seems to be an aggressive action taken towards its sustainability by the government and in this study, Nigeria. The study focuses on the need to understand the level of social drive in relationship to the performance attained by the informal entrepreneurs. In this regards, the propelling force to why the informal entrepreneur with governmental regulation have a positive performance and this was conducted in Computer village, Ikeja, Lagos. The explorative and causal research was adopted for the study. Survey research was considered appropriate for the study. 250 copies of questionnaire were distributed and 205 were returned depicting 82%. Analysis was done using the SPSS package and the hypothesis tested suggested that there is a significant relationship between social motivators and business competitiveness in the informal electronic market at 5 percent significant level, thereby accepting the alternate hypothesis. This study recommends that the place of family support has been noted to highly affect the motivation of the business and to this end, the basic support gotten from the government should be redesigned (i.e. schools, health, such that the remaining income will be used for expansion or transition while performance is primed.

    Full Text Available Data collected in over 50 years' activity at the C.N.R. meteorological station of Pallanza were analysed to see whether any changes have taken place in some climatic elements and to quantify the extent of such changes. A statistical analysis of the respective historical series was performed on nine meteorological parameters (solar radiation, insolation, air temperature, atmospheric pressure, humidity, cloud cover, precipitation, evaporation and wind, and on two other strictly limnological features: the level of Lago Maggiore and its water temperature at six different depths. In particular, we evaluated the means and the extremes (maxima and minima on an annual, seasonal, monthly and daily level, with the results presented uniformly for all the parameters, also in graphic form. We especially highlighted the trend lines, even though they were not always statistically significant owing to the extreme variability of the meteorological data; in the absence of statistical validity, their significance is an approximate indication of their increasing or decreasing trend. Results showed that insolation, air temperature and atmospheric pressure had increased markedly over time, at least on an annual level, with the trends for solar radiation, humidity and cloud cover also showing an increase, though very slight. Evaporation and wind showed a steady, marked decrease, while precipitation and lake level were essentially stable. Water temperature showed a more varied picture, with the temperature of the topmost levels (to a depth of 10 m continuing to increase.

    Full Text Available Background. Sickle cell disorders are known to have a negative effect on linear growth. This could potentially affect proportional growth and, hence, Cormic Index. Objective. To determine the Cormic Index in the sickle cell anaemia population in Lagos. Methodology. A consecutive sample of 100 children with haemoglobin genotype SS, aged eight months to 15 years, and 100 age and sex matched controls (haemoglobin genotype AA was studied. Sitting height (upper segment and full length or height were measured. Sitting height was then expressed as a percentage of full length/height (Cormic Index. Results. The mean Cormic Index decreased with age among primary subjects (SS and AA controls. The overall mean Cormic Index among primary subjects was comparable to that of controls (55.0±4.6% versus 54.5±5.2%; 54.8±4.5% versus 53.6±4.9% in boys and girls, respectively. In comparison with AA controls, female children with sickle cell anaemia who were older than 10 years had a significantly lower mean Cormic Index. Conclusion. There was a significant negative relationship between Cormic Index and height in subjects and controls irrespective of gender. Similarly, a significant negative correlation existed between age, sitting height, subischial leg length, weight, and Cormic Index in both subjects and controls.

    Samples of poultry droppings were collected from fifty poultry farms in Lagos area of Nigeria. Campylobacter species were isolated from serially diluted samples using Bolton selective enrichment medium under microaerophilic condition at 42 degrees C. Samples of water, both treated and untreated used in the farms were also analysed in the same manner. Fifteen Campylobacter strains were isolated from the droppings. All the strains were identified using biochemical characteristics differentiating Campylobacter species. They were identified as hippurate positive (C. jejuni) and negative species (C. coli). They were biotype' using the extended scheme described by Lior (1984). Campylobacter coli biotype 'I was the most prevalent (66.66%) followed by C. jejuni biotype 1 (20.00%). The biotype ii of the two species accounted for 6.67% each. The C. jejuni biotype III and IV were not isolated during the study. The preponderance of C. coli indicates that poultry can be a major reservoir for the spread of human campylobacteriosis. Poultry farmers, therefore, must ensure prompt and adequate means of disposal of waste materials as well as maintaining good sanitary conditions.

    A descriptive cross-sectional study was carried out to determine the prevalence of cardiovascular risk factors amongst traders in an urban market in Lagos State. Tejuosho market, one of the large popular markets was selected from a list of markets that met the inclusion criteria of being major markets dealing in general goods using a simple random sampling technique by balloting. Four hundred (400) traders were selected using a systematic random sampling. Each trader was interviewed with a well-structured questionnaire and had blood pressure and anthropometric measurements (height, weight and body mass index). Female traders made up (74.3%) 297 of the total population. The mean age was 45.48+11.88 and 42.29+10.96 years for males and females respectively. Majority 239 (59.8%) fell within the age range of 35 - 55 years. The cardiovascular risk factors identified and their prevalence rates were hypertension (34.8%), physical inactivity (92%), previously diagnosed diabetes mellitus (0.8%), risky alcohol consumption (1%), cigarette smoking (0.3%) in females and (17.5%) in males, obesity (12.3%) and overweight (39.9%). The study recommended that any health promoting, preventive or intervention programme for this population would have to be worked into their market activities if it is to make an impact.

    Full Text Available Com o crescimento da indústria sucroalcooleira, buscam-se alternativas de uso dos resíduos gerados por ela. Os pequenos ruminantes de raças naturalizadas do Nordeste brasileiro mostram-se como grupos potenciais para que seja utilizado o bagaço de cana-de-açúcar (BCA nas dietas. Nesse contexto, objetivou-se determinar a degradabilidade ruminal in situ da matéria seca (MS e da fibra em detergente neutro (FDN do BCA e os parâmetros ruminais em caprinos Moxotó e ovinos Morada Nova, fistulados no rúmen. Contidos em sacos de náilon, 3g de BCA foram incubados no rúmen nos tempos seis, 24 e 96 horas, determinando-se o conteúdo de MS e FDN nos resíduos obtidos. Nos tempos zero, seis e 12 horas após a primeira refeição, mediram-se no líquido ruminal pH e nitrogênio amoniacal (N-NH3 ruminal. O CMS não diferiu entre caprinos e ovinos. O potencial de máxima degradação da MS foi semelhante entre espécies, e da FDN foi superior em caprinos. Ovinos apresentaram maiores tempo de colonização, taxa de degradação e degradabilidade efetiva da MS e FDN. O pH não diferiu entre as espécies. Observou-se maior concentração de N-NH3 ruminal em caprinos, no tempo zero. Diante da maior velocidade de degradação da MS do BCA pelos ovinos, essa espécie se mostra detentora de uma microbiota ruminal com crescimento mais eficiente sobre o BCA.

    Full Text Available Em 2011 estimava-se que houvesse entre 12 a 15 mil crianças com Trissomia 21 (Martinho, 2011. A capacidade respiratória está relacionada com a permuta do ar atmosférico com o ar existente no interior dos pulmões (McArdle, Katch & Katch, 2001, sendo que este processo apresenta-se mais dificultado em sujeitos com Trissomia 21 pois exibem valores de pressão expiratória máxima abaixo dos 50% e de pressão inspiratória máxima abaixo dos 60% previstos para a população sedentária saudável (Castoldi, Périco & Grave, 2012. O treino de tiro com zarabatana tem influência no aumento da pressão expiratória máxima e tem um efeito sobre a função respiratória, semelhante ao treino muscular de músculos expiratório em adultos (Nagasaki, Okada, Kai, & Takahashi, 2010. Segundo (Mariñas & Higuchi, 2010 a zarabatana trata-se de um tubo comprido, através do qual são expelidos pequenos projéteis, através do sopro com objetivo de atingir um alvo. A introdução da atividade de tiro com zarabatana surge de modo a minimizar os problemas respiratórios desta população, porque envolve todo o ciclo respiratório e por ser uma atividade lúdica. Objetivo: Comparar os efeitos do treino de tiro com zarabatana na capacidade respiratória de pessoas com trissomia 21 após um ano de destreino.

    Full Text Available A questão ambiental está presente nas organizações e tornou-se uma preocupação das administrações e diretorias corporativas. Desta maneira, identificar quais são os desembolsos gerados pelas organizações no processo de adequação à legislação ambiental e na execução de atividades de gestão ambiental foi o problema de pesquisa deste trabalho. O objetivo foi propiciar ao leitor uma visão dos gastos realizados pelas entidades em transações que envolvam elementos ambientais, bem como retratar o papel da contabilidade ambiental. O trabalho se amparou em um estudo de caso realizado em uma indústria paulista localizada no Município de Mauá, com a devida autorização da empresa estudada, e se utilizou de informações fornecidas pelos departamentos contábil e ambiental. Foi possível concluir que os gastos de natureza ambiental despertam a atenção dos administradores, apesar de terem sido pequenos em termos relativos, comparativamente com os demais gastos, e a contabilidade figurou como fonte de informação aos administradores para que os impactos ambientais no resultado pudessem ser visualizados.

It also has one of the highest maternal mortality rates in the world with contraceptive prevalence among married couples less than 10%. Despite its safety and efficacy vasectomy appears to be unpopular in our environment. To assess the perception and acceptance of married men and women towards vasectomy and the influence of the spouse on the man's decision to accept or reject vasectomy. A cross sectional questionnaire based study. With an estimated population of 20 million, Lagos is the most cosmopolitan and urbanised city in Nigeria and accounts for 65% of all commercial activities in the country. Virtually all the tribes in Nigeria are represented in the city. Literate pregnant women recruited from the antenatal clinics and literate new fathers. All subjects were recruited from three health facilities in the Lagos metropolis. Twenty seven point five and twenty one percent of the men and women respectively had a good Knowledge of vasectomy while 49.1% and 19% of all men and women respectively with good knowledge would accept vasectomy (or agree for their spouses to have the procedure). Overall acceptance rates for men and women were 26 and 13.5% respectively while 92% of men who can opt for vasectomy will only do so if their spouses agree. Knowledge about vasectomy was the strongest single factor influencing the acceptance of vasectomy (p= 0.013) with stronger correlation among men than women (p=0.005 vrs p=.0.023). Knowledge and acceptance of vasectomy is significantly better in males than female Nigerians living in Lagos.

La “Global Biodiversity Information Facility” GBIF permite el acceso a más de 321 millones de registros, alojados en 379 instituciones. Los murciélagos neotropicales son un grupo muy diverso y especializado y la información geográfica del grupo se ha incrementado desde hace unos años, pero son pocos los reportes acerca del tema. El objetivo de este estudio fue analizar el número de registros disponibles en GBIF de los murciélagos neotropicales de 21 países de América. Por lo tanto, se evaluó la consistencia del nombre científico y la calidad geográfica a escala de país. Además, se evaluaron vacíos de información sobre una grilla de 1° latitud y 1° longitud. Hubo cerca de 1/2 millón de registros, de los cuales el 58% no incluyeron coordenadas geográficas; el 52% pasaron las dos evaluaciones. Se estimó que el 54% del área geográfica analizada no tiene registros; los vacíos están en centros de biodiversidad como la Amazonía y la Patagonia. En conclusión nuestros resultados sugieren que los datos disponibles en GBIF tienen sesgos geográficos y en los nombres científicos. Los datos de GBIF representan parcialmente las riquezas de murciélagos, además los principales vacíos de información se encuentran en América del Sur.

    In recent times, Lagos Island has been hit by a cyclical crescendo of juvenile crime perpetrated by "Area Boys," jobless youths who deal in robbery, extortion, and blackmail. Such deviant behavior has historical roots back to colonial times, when youths labeled "alkali boys," "boma boys," and "cowboys" roamed the heart of the capital of Britain's colony of Nigeria between the 1920s and 1960s. Examining the various types of juvenile delinquents on Lagos Island, this article explores the urban experience of criminally minded youths through exploration of street-life, vagrancy, criminality, and public reactions.

    The study of low energy cosmic particles allows to analyze several aspects of major interest for space weather. Ground detectors permit to observe secundary particles produced during the cascades developed in the atmosphere. The characterization of a prototype for a water Cherenkov radiation particles detector, in the frame of the LAGO collaboration (Latin American Giant Observatory), is presented in this work. The collaboration plans to install this detector at the LAGO antarctic site. The developed acquisition system and the method used to make the energy callibration of the detector are detailed here, as also corrections for atmospheric effects.

Trabajo con relatos registrados en contextos diversos y en soportes diferentes, que incluyen los circuitos mediáticos. Examino en ellos la articulación retórica del mensaje, cuyo contenido semántico se relaciona con creencias colectivas, entendidas como enunciados cuyo valor de verdad depende de un acuerdo intersubjetivo. Analizo la dinámica entre el saber experto de las ciencias y la narrativa de creencias, que intenta dar una respuesta totalizadora a problemas tales como la finitud de la vida o el temor a lo desconocido, para los cuales la ciencia canónica no brinda una respuesta satisfactoria.Neste artigo, eu analiso os limites entre a ficção e a história, a ciência e a opinião, em versões orais de versões orais e em recreações virtuais de duas matrizes narrativas: "A dama antasma" em seus nomes diferentes - de Rufina Cambacères a Frederike von Grottes e a Matilde di Canossa- e "O monstro de Loch Ness" conhecido em Argentina como "o Nahuelito". O alvo desta análise é estudar a dinâmica entre conhecimento científico relacionado com episteme, e o saber narrativo relacionado com a e crença. Eu acredito as crenças como expressões modais, consideradas como verdadeiras por meio de um acordo intersubjective. Neste sentido, as aparições espectrais e os monstro do lago podem ser considerados como expressões metaforicas do sobrenatural. De facto, tais criaturas tendem a dar rudimentos explanatórios do sentido simbólico da experiência que a ciência moderna não pode fornecer.This article analyses the boundaries between fiction and history, science and belief, in

Evidence of emergence and spread of this marker are lacking in Nigeria. This study investigated blaCTX-M-I ESBL production among Salmonella isolates from hospitalized patients.Methods: Patients (158 total made up of two groups were evaluated. Group A was composed of 135 patients with persistent pyrexia and group B was composed of 23 gastroenteritis patients and their stool samples. Samples were cultured, and isolates were identified and were subjected to antibiotic susceptibility testing by standard methods. Isolates were further screened for ESBL production, blaCTX-M-I genes and transferability by double disk synergy test, plasmid extraction, polymerase chain reaction, and conjugation experiment.Results: Thirty-five (25.9% Salmonella isolates were identified from group A, of which 74.3% were S. typhi, 22.9% were S. paratyphi and two (5.7% were invasive non-typhoidal S. enteritidis. Nine Plasmodium falciparum infections were recorded, four of which were identified as co-infections with typhoidal Salmonella. Only two (8.7% S. enteritidis samples were obtained from group B (P>0.05. A total of 24 isolates were ESBL-positive, eliciting resistance to five to seven antibiotics, and were multiple-drug resistant. ESBL production due to the blaCTX-M-I gene cluster was detected in eleven (45.8% Salmonella isolates. Nine (81.8% of the eleven blaCTX-M-I ESBL producers were S. typhi and two (18.2% isolates were S. enteritidis.

    Full Text Available Nigeria has one of the highest maternal mortality ratios in the world as well as high perinatal mortality. Unfortunately, the country does not have the resources to assess this critical indicator with the conventional health information system and measuring its progress toward the goal of ending preventable maternal deaths is almost impossible. Médecins Sans Frontières (MSF conducted a cross-sectional study to assess maternal and perinatal mortality in Makoko Riverine and Badia East, two of the most vulnerable slums of Lagos.The study was a cross-sectional, community-based household survey. Nearly 4,000 households were surveyed. The sisterhood method was utilized to estimate maternal mortality and the preceding births technique was used to estimate newborn and child mortality. Questions regarding health seeking behavior were posed to female interviewees and self-reported data were collected.Data was collected from 3963 respondents for a total of 7018 sisters ever married. The maternal mortality ratio was calculated at 1,050/100,000 live births (95% CI: 894-1215, and the lifetime risk of maternal death at 1:18. The neonatal mortality rate was extracted from 1967 pregnancies reported and was estimated at 28.4/1,000; infant mortality at 43.8/1,000 and under-five mortality at 103/1,000. Living in Badia, giving birth at home and belonging to the Egun ethnic group were associated with higher perinatal mortality.

    Full Text Available O bullying é uma forma de violência presente nas escolas e o termo é utilizado para caracterizar todas as formas de agressões repetitivas psicológicas e físicas, direta ou indiretamente. Esta violência causa sofrimentos, intimidação e medo, sempre numa relação de poder entre pares. Esta pesquisa trata de um estudo do bullying escolar: o que é, como surgiu, como identificá-lo e sua caracterização, conseqüências, causas, o papel da escola, de professores e pais e uma proposta prática que pode ser adotada para sua prevenção e contenção. O objetivo é organizar materiais para leitura dos atores educacionais para uma possível reflexão, através de pesquisas bibliográficas. Esta violência é grave e deveria ser tratada como saúde pública, devido às conseqüências que traz, como queda na aprendizagem, na autoestima e em casos mais graves, até o suicido e outras tragédias. A escola necessita atentar para esse tipo de violência, revendo suas ações em todos os momentos, tendo um olhar integral e diferenciado em relação aos alunos. É fundamental que o bullying não seja tratado como brincadeira de criança e para ser identificado e combatido é necessária uma ação entre a família e todos da escola, que pode ser desenvolvida através de projetos que ajudem a apontar caminhos para a solução do problema. Tais ações devem ser pautadas por constantes debates e reflexões, nas quais o aluno se torne o protagonista. Não existem fórmulas prontas, pois a intervenção deve ser feita através da realidade de cada escola.

    Full Text Available Abstract Background Infertility is a major problem in sickle cell disease patients, especially in males. In addition to low serum testosterone, other abnormalities involving the accessory sex organs, such as the seminal vesicles and the prostate gland, as well as marked decrease in ejaculate volume may be observed in male HbSS patients. Hence, the need to study the role of sex hormones as a cause of infertility in male HbSS patients. Methods An unmatched case-control study was performed using seventy-five consenting subjects from Lagos University Teaching Hospital. These included 47 patients with haemoglobin phenotype SS from the Sickle cell clinic and 28 volunteered medical students and members of staff with haemoglobin phenotype AA. Demographic data were obtained using a self-administered questionnaire. A total of 5 mls of blood was collected from each subject between 9.00 am & 11.am, and assayed for serum testosterone concentration. Results The concentrations of serum testosterone in HbSS patients ranged from 0.2 to 4.3 ng/ml with a mean of 1.28 ± 0.72 ng/ml whilst the values in HbAA controls ranged from 1.2 to 6.9 ng/ml with a mean of 2.63 ± 1.04 ng/ml. Seven (25.0% of the 28 controls had serum testosterone concentration lower than the quoted reference (normal range whereas 44 (93.6% of the 47 HbSS subjects had serum testosterone concentration lower than the reference range. Conclusion Overall, subjects with HbSS have significantly lower mean serum testosterone than HbAA controls.

    Full Text Available Background. Paediatric endoscopy is now standard care in the developed world for the management of gastrointestinal (GI disorders. However, in developing countries endoscopy remains an underutilised tool. Objective. To determine the indications and the spectrum of endoscopic findings in children seen at the Lagos University Teaching Hospital, Nigeria. Methods. The indications for upper GI endoscopy and endoscopic findings in children ≤16 years old, referred for the procedure from June 2013 to June 2016, were documented. The endoscopic yield in these children was also determined. Results. In total 71 children were referred for upper GI endoscopy during the study period. There were 35 boys and 36 girls aged 3 months to 16 years. The indications for upper endoscopy were recurrent abdominal pain in 37 (52.1%, upper GI bleeding in 17 (23.9%, recurrent vomiting in 7 (9.9%, dyspepsia in 5 (7.0, heartburn in 2 (2.8%, dysphagia in 1 (1.4, portal hypertension in 1 (1.4 and ingestion of corrosives in 1 (1.4% of the subjects. Endoscopic findings were as follows: gastritis 19 (26.8%, hiatus hernia in 13 (18.3%, gastric erosions in 12 (16.9%, oesophageal varices 6 (8.4%, duodenitis in 4 (5.6%, gastric ulcer in 3 (4.2%, gastric polyp in 2 (2.8%. The overall endoscopic yield was 60.2%. Conclusion. There is a need to increase the awareness of the role of paediatric endoscopy in the diagnosis and treatment of GI disorders in developing countries. Recurrent abdominal pain still remains a relevant indication for the procedure. The need to develop training programmes for paediatric endoscopy and paediatric gastroenterology in general in developing countries cannot be overemphasised.

  14. Bearded saki feeding strategies on an island in Lago Guri, Venezuela.

    Norconk, Marilyn A; Conklin-Brittain, Nancy L

    2016-05-01

    Free-ranging bearded sakis (Chiropotes spp.) live in relatively large social groups (22-65+), inhabit very large home ranges (200-1,000 ha), and travel long distances (1.8 to >7 km) each day. While these characteristics would seem to reduce their ability to occupy habitat fragments, several studies suggest otherwise. The key to their success may lie in their dietary adaptations. Bearded sakis are strongly frugivorous, but are primarily seed eaters, and are able to ingest both young and mature fruit. We examined feeding activities of a group of bearded sakis over a 19-month period on a 180 ha island in Lago Guri, Venezuela. Given their feeding adaptations, we predicted that they would minimize peaks and troughs in plant species used for food, limit seasonal variation in the mechanical properties of foods ingested, and balance ingestion of energy-rich foods (e.g. lipids, nonstructural carbohydrates (TNC), and/or free simple sugars). We found that bearded sakis on Danto Manchado had a diverse (plant-based) diet, but two resources (Pradosia caracasana, Sapotaceae, and Oryctanthus alveolatus, Loranthaceae) provided a stable dietary base and were present in the diet almost every month. Second, we found little variation in the mechanical-resistance properties of fruits opened seasonally. Third, they alternated months ingesting foods with high TNC content and months of high lipid content. This may be an attempt to balance energy intake from available foods. Finally, their social propensity to split up into subgroups may predispose them to reduce group sizes to accommodate smaller available areas. We suggest that bearded sakis use both ecological and behavioral mechanisms to survive in smaller-than-typical areas. Longer-term studies (beyond a few generations) of bearded sakis in habitat fragments would allow us to estimate minimum survival area and identify critical resources or resource combinations. © 2015 Wiley Periodicals, Inc.

    Full Text Available A capital investment appraisal is a means of ensuring value for money. It is not meant to provide an indication of profit or loss, but rather a comparison of costs in relation to those areas where there is an opportunity or an inclination for change. The decision to invest in a project is based on the expectation of future returns since a rational investor does not expect to incur loss on his capital outlay. This decision making is usually hinged on advice obtained during pre-investment appraisal. This study is aimed at evaluating the mode of practicing investment viability appraisal by Estate Surveyors and Valuers in Lagos metropolis. The data for the study was obtained by randomly administering structured questionnaires on eighty-seven (87 practicing Estate Surveyors and Valuers in the study area and the findings were analyzed through descriptive statistical tools such as the Likert scale to present the result. Findings revealed that the payback period is the most adopted appraisal technique in practice as evidenced with a mean score of 3.57. The objective (s of the investor is also the most significant factor being considered while selecting appraisal technique with a mean score of 3.83 while the problems of actual return varying from the expected return and also difficulty in the repayment of loans always result when a wrong viability technique is employed. The success of any viability study goes beyond knowing the objective (s of the investor; therefore, it was recommended that appraisers should ensure that they are equipped with adequate knowledge required for the execution of feasibility and on viability studies because knowing the right viability criteria for a particular objective will help in advising an investor on a course of action that will best achieve the developer’s objective.

Se efectuó un análisis de correlación simple entre la abundancia total de los coríxidos y las variables físicas y químicas registradas. Se registraron tres especies: Graptocorixa abdominalis (Say, 1832, con 53% de abundancia; Corisella edulis (Champion, 1901 con 43% y Krizousacorixa femorata (Guérin, 1857 con 1%. De un total de 2423 organismos capturados, la mayor abundancia se registró en marzo, junto con los valores más altos de profundidad y oxígeno. La menor abundancia se presentó en junio, con los valores más bajos de alcalinidad. La correlación de variables y abundancia total fue positiva y significativa con profundidad, oxígeno y conductividad. La Estación I presentó la mayor abundancia de coríxidos y la estación III la menor abundancia. Las variaciones registradas en la abundancia se deben al aporte de agua y a la ubicación de las estaciones de muestreo.

    Lago de Colina (Colina Lake) is located about 180 km south of the city of Chihuahua (Mexico), and during the Semana Santa (Holy Week) vacation period its recreational use is high. The objective of this study was to quantify coliform and heavy metal levels in this water body before and after the Holy Week vacation period in 2010. Twenty sampling points were randomly selected and two water samples were collected at each point near the surface (0.30 m) and at 1 m depth. After the Holy Week vacation the same twenty points were sampled at the same depths. Therefore, a total 80 water samples were analyzed for fecal and total coliforms and levels of the following metals: Al, As, B, Ca, Cr, Cu, Fe, K, Mg, Mn, Na, Ni, Pb, Se, Si and Zn. It was hypothesized that domestic tourism contaminated this water body, and as a consequence, could have a negative impact on visitor health. An analysis of variance (ANOVA) study was performed for each element and its interactions considering a factorial design where factor A was sample date and factor B was sample depth. Fecal coliforms were only detected at eight sampling points in the first week, but after Holy Week, both fecal and total coliforms were detected at most sampling points. The concentrations of Al, B, Na, Ni and Se were only statistically different for factor A. The levels of Cr, Cu, K and Mg was different for both date and depth, but the dual factor interaction was not significant. The amount of Ca and Zn was statistically different due to date, depth and their interaction. No significant differences were found for any factor or the interaction for the elements As, Fe and Mn. Because of the consistent results, it is concluded that local tourism is contaminating the recreational area of Colina Lake, Chihuahua, Mexico. PMID:21776236

    Full Text Available Durante las últimas décadas, las ciudades posindustriales latinoamericanas se han constituido como nodos de la red mundial. La apertura de sus economías nacionales, posibilitó que algunas de estas ciudades se conviertan en los lugares preferidos para la localización de funciones y actividades de enlace con las redes globales de carácter comercial, productivo, financiero y cultural. Estos espacios urbanos avanzan progresivamente hacia polos segmentados de desarrollo que se manifiestan en la sociedad a través del acceso diferencial a bienes y servicios, surgiendo una dualidad espacial, aparentemente planteada, entre el espacio público y privado, y promoviendo fenómenos de exclusión o inclusión en una tensión permanente. Así se configuran en archipiélagos promotores de cambio y sujetos a diversas dimensiones de análisis. Para interpretar este fenómeno en relación a la inversión de capital, se ha seleccionado como territorio de análsis, un área del sector noroeste de la ciudad de Córdoba, Argentina. Se trata de un complejo comercial de gran magnitud y significación simbólica para la ciudad: Grupo Dinosaurio. El presente trabajo ensaya una aproximación exploratoria para identificar las tensiones producto de los conflictos por el avance en el espacio urbano de inversiones en espacios segmentados, promotores de cambio y su relación con el espacio público- privado, y la consecuente segregación socio- espacial.

    Full Text Available Background: Cerebral palsy (CP is one the most common causes of disability among children in developing countries and is often associated with poor growth. The assessment of growth and nutrition of children is an important aspect of health monitoring and is one of the determinants of child survival. Aim: To assess the nutritional status of children with CP as seen in Lagos University Teaching Hospital (LUTH. Subjects and Methods: A prospective case-control study was conducted on children with CP attending the weekly pediatric neurology clinic of the LUTH between April 2005 and March 2006. Controls were apparently healthy children being followed up at the children′s out-patient clinic of LUTH for acute illness that had resolved. Anthropometric measurements of weight, length/height, mid-upper arm circumference, and skinfold thickness were taken according to the protocols recommended by the International Society of the Advancement of Kinanthropometry. Statistical Analysis: EPI-INFO (version 6.04 was used for analysis. Chi-square test was used to determine associations. Student′s t-test was used to compare means of patients and matched controls. Probability P < 0.05 were taken as statistically significant. Results: The controls had higher weight than the patients with mean weight (standard deviation of 13.7 (4.8 kg, and 12.0 (4.5 kg, respectively (P = 0.01. There were also statistically significant differences in the subscapular and biceps skinfold measurements between the patient and control groups (P = 0.00004 and 0.000008, respectively. Twenty-four (25.8% and 5 (5.4% of the patients had moderate and severe undernutrition compared to 6 (6.1% and none, respectively, in the control group (P = 0.00005. Conclusion: Children with CP had significantly lower mean anthropometric parameters and were more malnourished compared with the control group of children matched for age, sex, and social class.

    Full Text Available Background: Substance abuse refers to the harmful or hazardous use of psychoactive substances, including alcohol and illicit drugs. Use of drugs among adolescents is a global phenomenon eating deep into the fabrics of our society. Students are most vulnerable at this transformative stage in their life. Available report indicates that Nigeria is currently the highest consumer of cannabis and amphetamine in Africa. What is the prevalence of this abuse by students? Methodology: This research was a cross sectional descriptive design to identify the prevalence of substance abuse among students in public senior secondary schools in Mainland Local Government, Lagos. A sample size of two hundred and sixty two was determined and used from randomly selected five out of the nine public schools identified. Multi stage sampling (including simple random and systematic sampling and probability proportional to size methods were usefully employed in scientific selection of 262 samples and subsequent data collection in a total sample frame of 1,938 students. Self-administered questionnaire consisting of open and close-ended questions generated using research objectives was used in data collection. Result: It identified that 19.5% had smoked cigarette once or more in their lifetime. 77.2% had used alcohol once or more in a life time while 7.7% used marijuana, 8.4% tranquilizers and 1.9% cocaine all in a life time respectively. Conclusion: It recommended strict regulation of alcohol and tobacco products import and use in public places as well as aggressive dissemination of information on the dangers of substance use and abuse.
