    Full Text Available Avaliou-se o enraizamento de três tipos de estacas (semilenhosa, madeira semidura; semilenhosa, madeira dura e lenhosa de limeira ácida 'Tahiti', coletadas em três diferentes posições da copa (basal, medial e apical. Adotou-se o delineamento experimental no esquema fatorial 3x3 em blocos casualizados, com cinco repetições e 20 estacas/parcela. Os dados biométricos avaliados foram: percentual de enraizamento e formação de calo, número e comprimento médio de raízes, número de folhas/estaca enraizada e porcentagem de mortalidade. As médias foram comparadas pelo teste de Tukey ao nível de 5% de probabilidade. Observou-se que as estacas semilenhosas (madeira semidura apresentaram os melhores índices em relação a todas as variáveis analisadas, independentemente da posição de coleta na planta. Detectou-se que as estacas lenhosas apresentaram os piores índices, com exceção do comprimento e número de raízes das estacas coletadas na posição medial.

    Full Text Available Este artigo analisa o diário de Nathaniel P. Davis, embaixador estadunidense em San José, Costa Rica, que presenciou a Guerra Civil de 1948 e participou de sua resolução. O diário de Davis, deixado de lado por pesquisadores desse período, é importante por se tratar de uma das poucas fontes que construiu uma narrativa imediata ao desdobramento dos eventos que ocorreram na Costa Rica entre março e maio 1948. Assim, juntamente com outras fontes, esse diário é utilizado para fazer uma reconstrução das ações do diplomata, de sua percepção do conflito e das atitudes por ele tomadas para solucioná-lo.Enfim, através das anotações de Davis se reavaliam vários eventos importantes que foram impressos de forma quase imutável nas narrativas historiográficas costarriquenses sobre a guerra civil de 1948. O resultado é um texto que permite reavaliar esse acontecimento fundamental da Costa Rica contemporânea.

    Full Text Available The African hedgehog is one of the newly imported exotic pets which have been observed with increasing regularity in veterinary clinics in Costa Rica. Despite their popularity, information about their diseases is scarce. Within skin diseases of hedgehogs, mange caused by Caparinia spp. is a common diagnosis in other countries. Two adult African hedgehogs, one male and one female, were brought to a private clinic in Heredia, Costa Rica, with chronic pruritic dermatitis, scabs, nearly complete loss of spines, lethargy, dehydration, and weight loss. During physical exam, deposits of dry seborrhea were taken and processed for diagnosis. Microscopic examination revealed psoroptid mites identified as Caparinia tripilis. This is the first report of the presence of Caparinia tripilis in Costa Rica and, to the authors' knowledge, the rest of Central America. O ouriço africano é um dos animais de estimação exótico, recém-importado que tem sido observado com maior regularidade nas clínicas veterinárias da Costa Rica. Apesar da sua popularidade, informações sobre suas doenças são escassas. Dentre as doenças de pele de ouriços, a sarna causada por Caparinia spp. é um diagnóstico comum nos outros países. Dois adultos ouriços africanos, um macho e uma fêmea, foram levados para uma clínica particular, em Heredia, Costa Rica, com a dermatite pruriginosa crônica, crostas, perda quase completa de espinhos, letargia, desidratação e perda de peso. Ao exame físico, os depósitos de seborreia seca foram retirados e processados para o diagnóstico. O exame microscópico revelou ácaros (psoroptidae identificados como Caparinia tripilis. Esse é o primeiro relato da presença de Caparinia tripilis na Costa Rica e, para conhecimento dos autores, o resto da América Central.

    This discussion of Costa Rica focuses on: geography, people and history, government, political conditions, the economy, defense, foreign relations, and relations between the US and Costa Rica. In 1985 the population totaled 2.6 million with an annual growth rate of 2.6%. The infant mortality rate is 15.2/1000; life expectancy is 67.5 years for men and 71.9 years for women. Costa Rica, the 2nd smallest Central American country, is located in a narrow strip between Panama and Nicaragua. Costa Ricans are overwhelmingly of European descent. Although preominantly Spanish, there also are many Costa Ricans of German, Dutch, and Swiss origin. The indigenous Indian population numbers about 20,000, 20% fewer than inhabited Costa Rica when the Spanish first settled in 1522. Blacks, descendants of 19th century Jamaican immigrant workers, constitute a significant English-speaking minority of 30,000. Costa Rica is a democratic republic with a strong systems of checks and balances. The president and 57 legislative assembly deputies are elected for 4-year terms. Costa Rica's political system has contrasted with that of its neighbors. The nation has steadily developed and maintained democratic institutions and an orderly, constitutional process of government succession. Costa Rica faces severe challenges to its economic stability, although traditionally it is one of the strongest nations in the region. Increases in government spending in the late 1970s and higher world prices for coffee and other important Costa Rican exports stimulated the economy, creating inflationary pressure. The government is pursuing a course of disciplined management. The country is an outsponken and active member of the international community. The cordial relationship between Costa Rica and the US is based on mutual respect for democratic traditions, common goals, and a relationship free from serious political disagreement.

  17. Demand management by means of substitution energetics in home cooking: Costa Rica's metropolitan area; Gerenciamento da demanda mediante substituicao energetica na coccao residencial: regiao metropolitana da Costa Rica

    Energy Technology Data Exchange (ETDEWEB)

    Herrera, Alfonso Herrera

    1996-07-01

    The electric power system management in Costa Rica is analyzed. The possibility of substitution of LPG (Liquefied Petroleum Gas) for electric power, in home cooking, are identified as one of the most important program in order to reduce increasing load peak and energy requirements in electric power system of Costa Rica. The sustain ability of the substitution program stands on the current process of electric power supply. The primary power sources used in generating electric power in rush hours are oil-based; this process is less efficient than directly using LPG for home cooking. Large scale substitution with LPG in home cooking will reduce increasing electric power demand in peak hours, reducing subsidized electricity sales, with better use of combustibles presently imported, improving the country commercial balance and preventing or postponing electric power system expansion investments. Three different perspectives have been considered in evaluating economical effectiveness in substituting power sources: user, utility and society perspectives. Due to subsidized electric power prices, residential users do not enough interest in substituting of LPG for power source; unless LPG cookers are also subsidized. However, positive results for the distribution utility are enough in order to offer these kind of incentives. Explicit treatment of these kind of programs, including the efficiency increment as an available resource for electric power utilities in Costa Rica, will avoid the implantation of most of combustion plants now planned in current National Electric Power Plant expansion program.

    Full Text Available One event of three consecutive days and another of four consecutive days of Stratus clouds were registered at the Maceio airport on the northeast coast of Brazil. This is a very rare phenomenon for equatorial regions and it was analyzed using the high resolution (10km ETA model, NCEP reanalysis, satellite data and conventional data supplied by the Hydrometeorological Directory DHM-SERHI/AL and by the Department of Flight Protection of the Zumbi dos Palmares airport. Wave disturbance in the trade winds and weak ascendant movements at low levels (1000 and 925hPa were identified. At the same time, anticyclonic curvature at high levels formed descendant movements and subsidence inversion. These vertical movements combined with a stable layer between 850 and 700hPa created a very humid layer at the low levels. The precipitation forecasted by the ETA model with 24h antecedence presented a satisfactory result for an average quantity of precipitation. Nevertheless, the spatial distributions of forecasted and observed precipitation were different. Precipitation during all days was not forecasted for the coastal region, and for the west region the forecasted precipitation was more intense than the observed ones.Foram registrados dois eventos de três e quatro dias consecutivos de nuvens Stratus no aeroporto de Maceió na costa leste do Nordeste Brasileiro (NEB.

    Full Text Available En la localidad de Charambirá, situada en el município de Istmina (Chocó en la costa Pacífica de Colombia, se presenta un problema de malaria endémica asociada con grandes poblaciones de mosquitos Anopheles del subgénero Kerteszia (A. neivai. Estos se crían en las colecciones de agua formadas por plantas epífitas de la família Bromeliaceae, que son muy abundantes en los árboles de mangle. En esa localidad se estudiaron: fluctuación poblacional y algunos aspectos ecológicos y etológicos de los adultos de esa especie de mosquito, con el objetivo de determinar su papel en la transmisión de malaria. Todos los mosquitos fueron colectados por cebos humanos. Los picos máximos de actividad ocurrieron en las horas crepusculares de la mañana y de la tarde (5:30 a 6:30 y 18:00 a 19:00 horas. En el período nocturno la actividad intradomiciliar fue baja y no hubo ninguna durante el día. El estado gonadotrófico de las hembras colectadas durante nos picos de actividad, mostró la existencia de dos poblaciones de mosquitos: una, en su mayoría individuos jóvenes que buscan su alimento en las horas de la tarde y la otra compuesta por individuos mas longevos, que buscan su alimento en la mañana. El estudio de la variación estacional mostró que las poblaciones son bajas en los meses de poca precipitación, pero a medida que aumenta el índice pluviométrico, aumenta el número de mosquitos. Se discute la relación que existe entre la presencia de los mosquitos y la prevalencia de malaria humana; se sugiere que A. neivai puede ser el responsable de la transmisión de malaria en la zona estudiada.Na localidade de Charambirá, situada no Municipio de Istmina (Chocó, na costa do Pacífico Colombiano, ocorre um tipo de malária endêmica associada com grandes populações de Anopheles do subgênero Kerteszia (A. neivai.

    Full Text Available A ocorrência de naufrágios pode ser atribuída a vários fatores. Contudo, embarcações de pequeno porte usadas na pesca costeira, são geralmente mais suscetíveis aos fatores meteorológicos e oceânicos. O objetivo desse estudo foi analisar o comportamento da velocidade do vento e altura significativa de onda em relação à ocorrência de naufrágios na costa brasileira, entre os estados de Sergipe e Rio Grande do Sul. As frequências trimestral e mensal de naufrágios registrados entre Janeiro/2004 e Junho/2008 foram comparados com os ventos e com a altura significativa de ondas. As velocidades médias e máximas do vento nos dias e áreas de ocorrência, bem como a altura significativa de onda, foram comparadas aos valores históricos dessas variáveis. Foram observados ventos e ondas acima da climatologia em 54% e 46% das ocorrências de naufrágio, respectivamente. Em vários casos, o vento atingiu velocidades muito elevadas, sendo a provável causa para a ocorrência desses naufrágios. Os resultados apontaram para uma maior incidência de naufrágios em ambientes costeiros das regiões sudeste e sul do Brasil, com maior ocorrência entre os meses de março e agosto, envolvendo principalmente embarcações de pequeno porte (94%, utilizadas na pesca costeira. Os resultados encontrados reforçam a necessidade do envio de informações meteorológicas e oceanográficas para pequenas embarcações, em especial àquelas empregadas na atividade de pesca costeira.

O objetivo deste artigo é expor uma estratégia para que uma gama maior de classes sociais habitar neste tipo de projeto, através de uma política de subsídios com base em construção de prédios mistos que geram, em cada projeto, receitas que podem ser usadas em subsídios para famílias de baixa renda na cidade de San José, Costa Rica. Estabelece-se uma estratégia para definir o local dos projetos, bem como um modelo de gestão urbana e gerenciamento de projetos para implementar a estratégia. Como resultado definem-se os papéis de dois novos atores: a associação de habitação e a corporação municipal na gestão de projetos coletivos de habitação.

    Full Text Available A guerra naval atinge o seu ponto crítico no primeiro semestre de 1916. Os submarinos alemães infligem pesadas baixas na frota do império britânico, comercial e de guerra, ou seja, a maior marinha do mundo. É ao abrigo da aliança com o seu mais antigo aliado que, nesta conjuntura precisa da geopolítica militar, a Inglaterra pede ao governo português a requisição dos navios alemães surtos nos portos portugueses desde o início da I Guerra Mundial. Em resultado a Alemanha, a 9 de março de 1916, declara guerra a Portugal. Surge o convite do governo britânico para uma missão governamental, chefiada pelo ministro das Finanças Afonso Costa, se deslocar a Londres para negociar as condições financeiras e militares em que os navios serão alugados ao governo britânico, bem como as condições em que Portugal pode contrair em-préstimos para entrar na guerra.Palavras-chave: I Guerra Mundial, Diplomacia económica luso-britânica, Transportes Marí-timos, Afonso Costa_____________________Abstract: The naval war reached its peak during the first semester of 1916. The German submarines had inflicted a huge blow on the British Empire navy, the biggest in the world by that time, both at commercial and war levels. In this context, England asks the Portuguese government to require the German ships docked in Portugal since the beginning of World War I, under its oldest alliance that with Portugal. In result, Germany declares war on Portugal on the 9th of March 1916. The English government calls a governmental meeting with Portugal whereby Afonso Costa, the Minister Finance and head representative of Portugal, travels to London. Here, he negotiates the financial and military conditions under which the ships will be rented to the English government as well as the requirements for borrowing money to finance war.Keywords: World War I, Luso-British economic diplomacy, Maritime Transport, Afonso Costa

    Full Text Available AIR FLOW OVER THE TRÓIA PENINSULA AND THE COSTA DA GALÉ – In the summer, the Portuguese western coast is characterised by an evident dominance of north and northwest wind directions. Due the influence of the Arrábida mountain, the north wind suffers a deflection and blows from the west, southwest or even south over the Tróia Peninsula, where in the summer months there is a high frequency of wind directions between west and south. This deflection is much more frequent and better marked at night than at daylight. At daylight the strong north wind is channelled through a valley between Palmela hill and the Louro mountain and frequently blows over the Tróia Peninsula, in directions between north-northeast and north-northwest. At night, north and northwest wind speeds are generally lower and west and south winds blow all over the Tróia Peninsula towards Carvalhal, as result of the deflection caused by the Arrábida and Cabo Espichel. The wind directions between west and south, frequent at night on the Tróia Peninsula, are also intensified by the difference of temperature between the cool ocean and the warm water of the estuary.

    3.5 million people lived in Costa Rica as of mid-1997. There were 24 births and 4 deaths per 1000 population, respectively, contributing to the annual natural increase rate of 2.0%. Each woman in Costa Rica bears an average of 2.8 children during her reproductive lifespan and men and women were expected to live for 73 and 78 years, respectively. Costa Rica's low infant mortality rate and high literacy and life expectancy rates set it apart from the rest of Central America. Costa Rica is also the only country in the region which maintains no standing army. About 96% of the population is White or Mestizo, 3% is Black, and 1% is indigenous Indian. More than half of the country lives in San Jose and its metropolitan area, 6% of the country's total land area. Unemployment has run near 5% over the past 2 years, but much of the labor force is underemployed. Costa Rica's economy depends upon tourism and agricultural exports such as coffee, beef, and bananas. A large Intel factory opened in 1997. The government and Costa Rican environmentalists are planning a joint campaign to reconvert 80% of Costa Rica's pasture back to forest and tree crops. About 20% of the government's budget is spent upon education and the 93% literacy rate is the highest in the region. Government health services provide low-cost contraceptives to more than 75% of users and 75% of women use some form of family planning.

O artigo investiga as políticas dos Estados colonial e pós-colonial até a morte do presidente Félix Houphouët-Boigny, a era pós-Houphouët e suas crises política e socioeconômica, e a má administração do legado de Boigny, que levaram ao conflito interno. As conseqüências da disputa interna também são investigadas nos níveis nacional e sub-regional, assim como as resoluções dos conflitos por meio das ineficientes iniciativas de paz de Accra que, inexoravelmente, levariam às conversas de paz de Lina-Marcoussis. Os resultados das negociações, a participação de poderes não africanos e o futuro da democracia na Costa do Marfim também são investigados.This paper uses descriptive method to analyse the origin and the seemingly intractable but avoidable ancillary factors that plunged Côte d'Ivoire, which was once the island of political stability, the showcase of economic prosperity and success in West Africa in the fangs of civil war. The paper surveys the policies of the colonial and postcolonial state till the death of President Félix Houphouët-Boigny, the post-Houphouët era and its lot of political and socio-economic upheavals and the mismanagement of the legacies of Boigny that led to the internal conflict. The consequences of the civil strife are also surveyed at the national and sub-regional levels as well as the resolutions of the conflict through the botched Accra peace initiatives that inexorably led to the Lina-Marcoussis peace talks. The aftermath of the negotiations and the involvement of extra-African powers and the future of democracy in Côte d'Ivoire are also looked into.

Usou-se 13 anos de dados ininterruptos de precipitação estimados através do algoritmo 3B42_V6 do projeto TRMM. Os ciclos foram analisados por quadrimestres. Para obter informações sobre amplitude, fase e fração de variância de cada ciclo, utilizou-se a análise harmônica do ciclo composto no período de 24 horas para cada quadrimestre. Regiões mais próximas da costa apresentaram ciclos modulados por mecanismos oceânicos e, portanto, tendem a apresentar o máximo de precipitação no início da manhã e a noite. Regiões mais afastadas da costa apresentaram máximos às 2100 UTC (17:00 HL em função dos mecanismos de convecção local. A região Nordeste do Pará apresentou as maiores amplitudes de precipitação. Durante o quadrimestre de janeiro a abril observou-se as maiores taxas de precipitação. Não há variações sazonais significativas na fase dos ciclos. Os dois harmônicos correspondem a cerca de 80% do total da variância diária dos dados. No final, algumas sugestões de trabalhos futuros e aplicabilidade dos dados do 3B42_V6 são discutidas.The diurnal and semidiurnal rainfall cycles observed over the Brazilian North coastland were studied.

    Costa Rica's demographic and economic characteristics are highlighted. Costa Rica's demographic situation is unique in certain respects. Between the late 1950s and the late 1970s, the total fertility rate declined from about 7 to 4 and then stabilized instead of continuing to decline to 2 as expected. This is especially surprising since the level of contraceptive use is similar to that of most European countries. Approximately 2/3 of all couples practice contraception. It is possible that the rate will slowly decline to the expected level, but a delayed decline will ultimately produce a much larger population than initially expected. The demographic situation in Costa Rica is being carefully monitored for insights which might be useful in predicting future fertility patterns in other developing countries. The government of Costa Rica recognizes that family planning is a necessary component of maternal and child health care; however, most family planning services are provided by private organizations. In 1982, population size was 2.6 million, the crude birth rate was 30.7, the crude death rate was 3.9, infant mortality was 19.3, and the rate of natural increase was 2.7%. The population is predominantly Spanish, and the indigenous population totals only 20,000. 48% of the population is urban. Costa Rica has a relatively stable deomocratic government. It relationshiops with other countries are generally peaceful, but tensions between Nicaragua and Costa Rica are increasing. The country's economic situation deteriorated in recent years due primarily to a decline in the price of coffee, the country's principle export commodity. The trade deficit increased markedly, unemployment increased, and income fell sharply. The economic slowdown is now showing signs of a reversal. In 1983 exports, consisting primarily of coffee, bananas, beef, sugar, cane and cacao, totalled US$871 million, and imports, consisting mainly of manufactured goods and equipment, chemicals, fuel, food

Abre-se o caminho para que a própria dinâmica destes conflitos seja entendida como fator de construção da sustentabilidade. Este texto procura documentar e discutir um episódio de conflito ambiental, tomando a experiência de discussão pública, negociação e votação do Plano Diretor Municipal de São Sebastião, município da costa norte de São Paulo. Pretende-se discutir o avanço possivel em termos de mediação de conflitos, com utilização de técnicas de negociação, e a relação deste processo com a dinâmica da política local, em especial marcando os papéis do Executivo e do Legislativo no processo participativo. O principal tema que emerge em relação à pauta da sustentabilidade é a competição entre o turismo e o veranismo na ocupação do território costeiro.Environmental problems may be understood as conflicts between different actors. This represents an alternative approach related to the conceptualy poorer opposition between nature and anthropic actions,which generalize to whole society predatory patterns of relationship with environment. Dealing with the concept of environmental conflicts, we may recognize different forms of society-nature relation, and diverse concrete interests, associated to the various uses of environmental resources. This opens, besides, the possibility to understand the conflicts dynamics as something that may contribute building sustainability. This text intends to describe and discuss an environmental conflict episode, the

Foram avaliadas, comparativamente, as dimensões da folha e, em microscopia de luz, a espessura dos tecidos foliares, a densidade de estômatos e de cristais da espécie, coletada em área rural e em dois pontos da cidade de São Paulo: canteiro central da Avenida dos Bandeirantes, com tráfego veicular intenso, portanto com alta carga de poluentes primários, e no Parque Estadual das Fontes do Ipiranga (PEFI submetido a altas concentrações de poluentes secundários. Buscaram-se variações que possam ser decorrentes da poluição urbana. As folhas coletadas no meio urbano mostraram menores dimensões, menor espessura do mesofilo, maior densidade estomática e maior quantidade de cristais. A espessura do parênquima lacunoso sofreu redução, quando se comparam as plantas do ambiente rural e urbano; observou-se a menor espessura nas folhas submetidas a poluentes secundários. Não foram observadas variações qualitativas entre as folhas dos três locais avaliados. Considerando que folhas coletadas no meio urbano variaram menos entre si, quando comparadas àquelas de área rural, acredita-se que a poluição aérea da cidade possa ser responsável, pelo menos em parte, pelas variações observadas. Exposições padronizadas, em ambiente monitorado, devem ser realizadas para comprovar tal hipótese.The aim of this study was to compare leaves of Eugenia uniflora from the city of São Paulo with leaves of plants from a rural site.

    Santa Catarina é responsável por aproximadamente 93% da produção de mexilhões (Perna perna e ostras (Crassostrea gigas cultivados no país. Embora possuam grande valor nutricional, eventualmente podem representar risco para a saúde do consumidor quando contaminados por agentes tóxicos, como por exemplo, toxinas produzidas por algas, ou ficotoxinas. Algumas ficotoxinas nocivas aos seres humanos têm como vetores os moluscos filtradores que podem acumular essas substâncias nos tecidos quando espécies de microalgas produtoras de toxinas estão presentes na água. A saxitoxina, produzida por alguns dinoflagelados, provoca a Síndrome do Envenenamento Paralisante pelo consumo de Moluscos, do inglês, Paralytic Shellfish Poison - PSP, que é um sério problema para a aqüicultura. Este estudo descreve a contaminação de mexilhões Perna perna por ficotoxinas da PSP com origem na ocorrência da microalga Gymnodinium catenatum em águas marinhas do litoral norte de Santa Catarina nos meses de abril e maio de 2006. Foram coletadas 22 amostras de água do mar e mexilhões em 10 pontos do litoral abrangendo 175Km da costa do Estado. As análises envolveram contagem de algas nocivas na água por microscopia óptica e a quantificação de ficotoxinas da PSP na carne de mexilhões através de bioensaios com camundongos e de cromatografia líquida de alta eficiência - HPLC. Os resultados comprovam a ocorrência, em baixas concentrações, destas ficotoxinas na carne de mexilhões cultivados e mostram a necessidade da inclusão desses contaminantes como parâmetro para a certificação da qualidade de moluscos bivalves destinados ao consumo humano.

The chemical composition was determined by fingerprint analysis in HPLC/ DAD. A weak inhibition of the second phase of the nociceptive effect induced by formalin indicated an activity similar to those steroids and not-steroids anti-inflammatories. Despite being prepared by decoction of five plants, the fingerprint analysis showed only two peaks. None of them corresponds to the chemical compounds observed in ethanol extracts prepared with the same plant material. We argue that the methods of preparation of the formulas should be considered in studies of multi-herbs products, since they can be the responsible for inefficacy or low activity of such products.Plantas medicinais nativas do Brasil foram usadas por décadas pelas indústrias farmacêuticas nacionais para criar seus produtos.

J. van Bénéden, 1864, were compared between two populations along the Brazilian coast: Caravelas (Bahia, along the eastern coast, and Norte Bay (Santa Catarina, along the southern coast. Applying the focal-group sampling in both areas, information such as the geographic position (UTM of groups and predominant behavioral patterns were obtained. Geographic positions were used to calculate the total distance traveled by estuarine dolphin groups on each observation day. Since the distance traveled varies with time, the daily mean speed of the dolphin’s group was used as an index of movement intensity. Two comparable and easily recognizable behavioral patterns were considered: travelling and foraging. Overall movement intensity and behavioral pattern frequency were similar between both areas. However, a seasonal variation was observed in both parameters in Norte Bay, while in Caravelas these parameters were homogeneous throughout the year. Variation in the behavior of the estuarine dolphin was consistent with variations in environmental factors, such as water temperature.Os padrões comportamentais do botocinza, Sotalia guianensis (P.

Utilizando o método de grupo-focal em ambas as áreas, informações como posições geográficas (UTM do grupo e padrão comportamental predominante foram coletadas. A posição geográfica foi utilizada para o cálculo da distância total percorrida por um grupo de botos-cinza em cada área de observação. Como a distância é uma medida que varia com o tempo, a velocidade média diária do grupo de botos foi usada como um índice de intensidade de movimento.

    Full Text Available The present study is a compilation of the literature about vegetation of mangrove forest of the north coast of Brazil. It synthesizes the knowledge about this important ecosystem and lists the currently available literature. The study focuses on the coast of Pará and Maranhão states, which are covered by a continuous belt of mangroves. The mangrove flora comprises six mangrove tree species and several associated species. Mangrove tree height and stem diameter vary as a function of abiotic local stand parameters. Seasonal variation in rainfall and salinity affect the species' phenology and litter fall. Local population use products derived from mangrove plants for different purposes (e.g. fuel; medicinal; rural construction. The increase in the coastal population has given rise to conflicts, which impact on mangrove forest.O presente estudo apresenta uma compilação da literatura sobre a vegetação dos manguezais da costa norte do Brasil, apresentando uma síntese do conhecimento e listando a literatura disponível. O estudo se concentra na costa dos estados do Pará e Maranhão que formam um cinturão contínuo de manguezais . Foram contabilizadas seis espécies arbóreas exclusivas de mangue e várias outras associadas. A altura e o diâmetro das árvores de mangue variam em função de parâmetros abióticos locais. As variações sazonais do regime de chuvas e da salinidade afetam a fenologia das espécies e a produção de serapilheira. A população costeira utiliza a flora do manguezal para diferentes fins (ex: combustível, medicinal, construção rural.

Se notó que los riesgos de mortalidad por enfermedades infecciosas, cáncer, enfermedades crónicas pulmonares, enfermedades cardiovasculares, y enfermedades crónicas del hígado eran significativamente reducidos entre los inmigrantes nacidos en Nicaragua. El exceso significativo de mortalidad por homicidios se encontró entre los hombres nacidos en Nicaragua (RT = 1,35, 95% IC: 1,19; 1,53 y en mujeres (RT = 1,41, 95% IC: 1,02; 1,95. El riesgo relativo de causas de mortalidad de origen de tipo exógeno entre los inmigrantes nicaragüenses fue más grande entre los grupos de edad joven en áreas de baja densidad de inmigrantes nicaragüenses. La población nacida en Nicaragua residiendo en Costa Rica tiene un riesgo reducido de mortalidad por causas generales versus las personas nacidas en Costa Rica en los años entre 1996-2005. Esto se debe a una mortalidad por enfermedad reducida, la cual es bastante marcada. El homicidio es un una razón de mayor mortalidad entre los inmigrantes nacidos en Nicaragua versus los nativos costarricenses. Hay una gran necesidad de llevar acabo investigaciones adicionales sobre el rol de la migración, estatus socioeconómico y comportamientos entorno a la salud para poder explicar más a fondo los patrones de mortalidad diferenciales entre los inmigrantes nicarag

  13. Mercury Contamination in Costa Rica

    2012-12-01

    Recent measurements of Hg in air in the central valley of Costa Rica produced some remarkably high values (up to 700 ng Hg/m3;Castillo et al., 2011), raising concerns for public health. We made a broad assessment of Hg as an environmental contaminant in Costa Rica, and sampled and analyzed lake and wetland sediment and soils to derive atmospheric Hg deposition rates. We also measured Hg(0) in air in three locations, and sampled local fish that were analyzed for Hg. We set up a sampling program of Hg in hair of Costa Ricans, sampling hair from a broad crossection of the population, in combination with dietary and personal information. The lake sediments had Hg concentrations between 34 and 316 ppb Hg, with several lakes at common natural background concentrations (20-100 ppb Hg). Some lakes showed a Hg contamination component with concentrations well above simple background values. These sediments also were very rich in organic matter, and the high Hg concentrations may be a result of Hg focusing from the watersheds into the lake depositional environments. Deduced atmospheric deposition rates of Hg range from 0.16-0.25 ng Hg/cm2 per year, which is at the low end of the global range of measured wet atmospheric deposition rates. The observed Hg concentrations in sediment and soils thus can be characterized as natural background to mildly contaminated, but nothing that would indicate Hg inventories as expected from the reported high Hg air burdens. Some of our Hg(0) in air measurements were done at the same locations as those done earlier and yielded values between 0.6-4.2 ng Hg/m3; these values are similar to the low range measurements of Castillo et al. (their night time values), but we found no evidence in 2011 for their high daytime values. The range of a few ng Hg/m3 in air is compatible with global Hg dispersion modeling. Fish tissue of Trout and Tilapia gave a range of 68-112 ppb Hg (wet weight base), well below the 300 ppb Hg EPA alert level. Overall, these

Dessa forma, o intuito deste trabalho foi determinar os parâmetros farmacognosticos para o estabelecimento do controle de qualidade da droga vegetal composta pelas folhas de Erythroxylum suberosum A. St.-Hil., pertencentes à família Erythroxylaceae ocorrente no Cerrado. Para tanto, foram coletadas folhas adultas nas proximidades da Universidade Federal de Goiás, Goiânia-GO. Foram determinados o teor de umidade por meio de balança com irradiação de raios infravermelho e o teor de cinzas totais. Na prospecção fitoquímica foram pesquisadas as classes de metabólitos secundários e realizou-se o doseamento de fenóis totais, flavonoides e taninos totais. Os resultados dos testes de pureza realizados, teor de umidade e teor de cinzas totais, estão de acordo com os limites estabelecidos pelas especificações farmacopeicas. As análises fitoquímicas evidenciaram a presença de flavonoides, taninos, cumarinas, saponinas e resinas. No doseamento de fenóis totais, taninos e flavonoides presentes nas folhas de E. suberosum A. St.-Hil. obteve-se respectivamente 17,97%, 6,31%, 3,87%. Estes resultados confirmam os dados da literatura quanto à presença destes compostos em Erythroxylaceae, pois de acordo com nas folhas de E. tortuosum obteve-se valores de 10%, 8,4% e 0,064% de Fenóis, Taninos e flavonoides, respectivamente e nas folhas de E. deciduum foram encontrados 12,04% de fenóis totais, 0,87% de taninos e 1,37% de flavonoides. Os resultados encontrados no presente trabalho também se tornam relevantes quando comparadas as quantidades desses metabólitos com espécies clássicas na biossíntese de compostos fenólicos como o teor de taninos de Stryphnodendron adstringens (Mart.

    Full Text Available Desde o começo da ocupação humana no litoral centro-sul de Santa Catarina, Brasil, a articulação entre processos naturais e antrópicos modelou uma paisagem fortemente domesticada, marcada pela construção massiva de concheiros de dimensões monumentais e pela permanência milenar. Na planície costeira entre Passagem da Barra (município de Laguna e lago Figueirinha (município de Jaguaruna, 76 sambaquis foram mapeados, dos quais 48 possuem datação. O levantamento sistemático de sítios e datações permitiu identificar padrões de distribuição espacial nos sambaquis da região, quanto a contexto sedimentar da época de construção, estratigrafia e idade. Desse modo, reconheceram-se nos sítios da região: cinco contextos geológico-geomorfológicos de localização; três padrões estratigráficos; e quatro fases de ocupação sambaquieira baseadas na quantidade de sítios e no tipo de padrão construtivo dominante. O modelo integrado de evolução sedimentar e distribuição tempo-espacial de sambaquis indica que estes sítios eram construídos em áreas já emersas e pouco alagáveis, e que sítios interiores, afastados dos corpos lagunares, podem não se ter preservado ou não estarem expostos devido ao processo de assoreamento contínuo que caracterizou a região após a máxima transgressão holocênica. O cruzamento de dados aqui proposto evidencia a importância de abordagens integradas entre arqueologia e geociências no estudo da evolução das paisagens.

A análise de correlação de Pearson confirmou a relação positiva (r = 0,90, P <0,0001 entre o comprimento do corpo e o comprimento da coroa opercular. Indivíduos com opercular crown < 0,9 mm podem ser considerados como juvenil devido à ausência de gametas.

Em período de elevadas taxas de juvenis, a densidade populacional atingiu 128.115 ind./m², porém, a média foi 65.090±22.033 ind./m². As análises estatísticas (Kruskal-Wallis H = 18,475, p < 0,01 revelaram existir variação significativa na composição juvenil entre as estações chuvosa e seca. Apesar da presença de juvenis em meses de seca, as estações chuvosas contemplaram 92,1% dos juvenis amostrados. O padrão de juvenis observado pode estar relacionado com fatores biológicos (e.g. gametogênese e ciclo de vida e abióticos (e.g. suprimento alimentar e correntes marinhas. Estes resultados destacam a necessidade de programas de monitoramento de longo prazo que integrem elementos ecológicos e abióticos, a fim de obter uma compreensão mais completa da ecologia desse poliqueta e ajudar a gerenciar a biodiversidade marinha do PEJX.

Nueve familias: 1 con JOAG, 1 con PCG y 7 con COAG se estudiaron en busca de mutaciones en los genes conocidos. Una duplicación de 10 pb, 1546-1555dupTCATGCCACC, en el gene CYP1B1, causa glaucoma en condición homocigota en una familia consaguínea con PCG. Esta mutación se ha encontrado en otros países y origina un codón de terminación prematuro que codifica una proteína 140 aminoácidos más corta que la normal. En dos de las familias con COAG se encontró una variante inocua Arg76Lys en el exón 1 del gen TIGR/MYOC. Otros pacientes presentaron, en el gene OPTN, dos variantes en la region codificante (Thr34Thr, Met 98Lys y 7 cambios intrónicos. Una de las familias con COAG cumple con los requerimientos mínimos para un análisis de ligamiento, por lo que se utilizaron 379 marcadores microsatelíticos para mapear el gen causante de la enfermedad. No se obtuvieron valores LOD que claramente implicaran a alguna región cromosómica. La evidencia señala que el glaucoma hereditario en Costa Rica tiene una gran heterogeneidad genética y que es muy posible que los estudios que se desarrollan vayan a descubrir nuevos genes involucrados en la patología.

    Even though Costa Rica is underdeveloped economically, life expectancy has been increasing over the past decade and the illiteracy rate was only 7% in 1984. Infant mortality rates have plummeted since 1972 when the 1st national health plan and social security were instituted (pre-1972: 2.3% annual reduction in infant mortality; 1972-1980: 13% decline annually). Decreased risk in the 1st postnatal month of life was responsible for 34% of the decrease from 1972-1980. Control of disease, especially diarrhea and acute respiratory infection, accounted for most of the decline (51%). Immunizations accounted for 8%, prevention of infectious diseases for 10%, control of malnutrition for 5%, and control of death due to premature birth for 14% of the decrease in mortality. Infant death due to pregnancy and delivery complications and congenital defects did not decrease during this period. Socioeconomic conditions normally influence survival rates strongly, but socioeconomic change in Costa Rica during 1970-1980 accounted for only 1/3 of the reduction in infant mortality. These improvements included an increase in the number of educated women, economic growth and decline in fertility (a decrease from 7.6 to 3.4 births between 1960-1980). The majority of the reduction stemmed from utilization of family planning techniques and the reduction of health risk factors. By 1980, the health program initiated in the 1970's provided primary care to 60% of the population, immunized 95% of the children against poliomyelitis, diptheria, pertussis, tetanus, and measles, and by 1984, provided almost all households with a sewage system. Analyses of the impact of socioeconomic development, fertility regulation, hospital care, outpatient services, and primary health care on infant mortality showed that, before 1970, those areas with better economies had a lower mortality rate, and after 1970, the economy and mortality rate had become independent variables. Furthermore, the introduction of health

    Full Text Available Neste estudo foram realizados experimentos numéricos com um modelo meteorológico regional a fim de verificar o impacto dos Fluxos de Calor Latente (FCL e Calor Sensível (FCS em superfície no desenvolvimento de um ciclone intenso ocorrido sobre a costa leste da região sudeste da América do Sul, entre os dias 24 e 26 de julho de 1998. A taxa de intensificação do ciclone foi reduzida em 6 hPa/24 h no experimento em que os FCL e FCS estavam ausentes. Verificou-se que a ausência do FCL apresentou maior impacto do que a ausência do FCS, fazendo com que a taxa de intensificação fosse reduzida em 6 hPa/24 h para o experimento sem FCL e permanecesse inalterada sem FCS, mas neste último a isóbara de menor valor no centro do ciclone ocupou uma área menor. A ausência dos FCL e FCS em superfície gerou uma camada mais seca e mais fria próxima à superfície oceânica, reduzindo a instabilidade potencial do ambiente e diminuindo a intensificação do ciclone. Concluiu-se, portanto que os FCL e FCS em superfície foram importantes antes da fase de mais rápido desenvolvimento do ciclone, agindo no sentido de preparar o ambiente para uma ciclogênese mais intensa, através do fornecimento de energia e umidade para a baixa troposfera. Na fase de mais rápido desenvolvimento, a energia e a umidade disponíveis nas camadas mais baixas da atmosfera (inseridos na fase anterior também foram importantes, permitindo ao ciclone se desenvolver mais intensamente do que ocorreria em um ambiente mais seco e menos instável termicamente.Numeric experiments were run with meteorological regional model with the purpose to verify the impact of both latent and sensible surface heat fluxes (FCL and FCS, respectively during the development of an intense east cost cyclone over southeastern region of South America from 24 to 26 July, 1998.

    Full Text Available Mosquito collections were made in and near Costa Marques, Rondonia, Brazil, to determine anopheline anthropophilic/zoophilic behavior. Collections from a non-illuminated, bovine-baited trap and indoor and outdoor human-bait collections were compared. Anopheles darlingi and Anopheles deaneorum were more anthropophilic than the other anophelines collected. The remainder of the Anopheles species were collected much morefrequently in bovine-baited traps than in human-bait collections. Anopheles darlingi and An. deaneorum were more frequently collected inside houses than the other anopheline species. But, when collections were made in a house with numerous openings in the walls, there were few differences in the percentages of each species biting man indoors versus outdoors. Anopheles darlingi was the predominant mosquito collected, both inside and outside houses, and had the strongest anthropophilic feeding behavior of the anophelines present.Para determinar o comportamento antropofilico e zoofilico dos anofelinos, foram capturados mosquitos na periferia e na zona urbana de Costa Marques, Rondônia, Brasil. Foram comparadas as capturas feitas à noite, com iscas bovinas e humanas, dentro efora de casa. O Anopheles darlingi e o Anopheles deaneorumforam mais antropojilicos do que os outros anofelinos capturados. O restante das espécies anofelinas foi capturado mais freqüentemente nas iscas bovinas do que nas humanas. Anopheles darlingi e Anopheles deaneorumforam capturados dentro de casa com mais freqüência do que as outras espécies anofelinas. Porém, quando a captura foi feita em casas com muitas aberturas nas paredes houve pouca diferença nas porcentagens de cada espécie sugadora de humanos dentro efora de casa. Anopheles darlingi foi o mosquito capturado com mais freqüência, dentro e fora de casa, e apresentava maior antropofilia em relação aos outros anofelinos presentes.

    Full Text Available This new building is intended to house the various services of the Central Bank of Costa Rica. It has a prestressed concrete structure, and consists of a basement parking space for 105 vehicles, and nine storeys, providing altogether a floor surface of 12,000 ms2. The building rests on a ground area of 40 by 60 ms, and the main structure occupies 22 by 45 ms. This Bank is located in a district of narrow streets, but its main side overlooks a green open space, which will improve its visibility and appearance. The building structure is made up of a framework of prestressed beams and columns. The beams have been concreted at the site, and the joists, which are also prestressed, are factory made. This framework, at each floor level, constitutes the basis of a continuous slab, which renders the total structure exceedingly stiff. The main continuous girders span 11.22 ms spaces, and vary in cross section. The prestressing reinforcements consist of 6 Loeba type cables. This is an original design by Dr. Leonhardt, in which the cables are placed on three horizontal layers, of parabolic outline. Each cable is made up of 12 x 5.4 mm wires, with a breaking stress of 180 kg/mm2 The tensioning stress was 108 kg/mm2, and the total prestress load is 29,700 kgs. The cables run in corrugated metal tubes, and these were kept in precise position with the aid of distance pieces.El nuevo edificio, destinado a agrupar los servicios del Banco Central de Costa Rica, está constituido por una estructura de hormigón pretensado.

Contrairement à la côte caribéenne du Mexique qui a souffert du développement du tourisme de masse à Cancun et le long de la Riviera Maya, la Costa Maya s'est orientée vers un développement durable avec notamment une faible densité de construction et le développement de l'écotourisme.Le développement s'est concentré autour de Puerto Costa Maya où un terminal de croisière a été construit en 2001. La station balnéaire (balneario de Majahual est devenue dépendante des 10-12 bateaux de touristes qui débarquaient chaque semaine. En dépit d'importants plans de développement, les plages reculées de la Costa Maya accueillaient tout au plus des écotouristes aisés et du tourisme lié à la plongée sous-marine.Le cyclone Dean, de catégorie 5, a dévasté le paysage en août 2007 et le rétablissement économique n'a pu être entamé que fin 2008, après la réouverture du terminal de croisière et la reconstruction de Majahual. Fin 2009, le trafic de croisière n'a pas retrouvé son niveau d'avant Dean et la récession mondiale couplée avec la grippe porcine et les violences liées à la drogue ont fait diminuer le tourisme en provenance des Etats-Unis.

Desta forma, este trabalho reporta o estudo preliminar toxicológico, antibacteriano e fitoquímico do extrato etanólico das folhas de Jatropha mollissima (pinhão-bravo, Euphorbiaceae, coletada no Município de Tauá, Ceará, Nordeste Brasileiro. Inicialmente, realizou-se o teste de toxicidade do extrato contra Artemia salina. Na sequencia, foi realizado o ensaio antibacteriano contra quatro cepas bacterianas Gram-negativas (Escherichia coli ATCC 25922, Pseudomonas aeruginosa ATCC 27853, Hafnia alvei ATCC 51873, Klebsiella pneumoniae ATCC 13883 e uma cepa Gram-positiva (Enterococcus faecalis ATCC 29212. Finalmente, fez-se a análise fitoquímica preliminar do extrato ativo para detecção das principais classes de metabólitos especiais. Como resultado, o extrato etanólico das folhas de J. mollissima se mostrou tóxico para Artemia salina, pois apresentou CL50 igual a 406,02 μg/mL. Quanto à ação antibacteriana, o extrato se mostrou ativo contra a bactéria Gram-positiva Enterococcus faecalis ATCC 29212, apresentando moderada atividade antibacteriana (halo de inibição igual a 7,03 mm. Evidenciou-se no extrato bioativo a presença de cumarinas, fenóis, taninos, flavonoides (flavonóis e flavanonas, alcaloides e esteroides, ambas as classes reportadas como antimicrobianos. Portanto, esse extrato tem potencial para ser usado na produção de fármacos contra infecções causadas por bactérias Gram-positivas. No entanto, as informações direcionam estudos futuros para o isolamento e identificação dos compostos bioativos, monitorados sob a ação antibacteriana mais expressiva.

Changing rooms for bathers, and a night club, in the basement. Restaurant and bar on the ground floor. Twelve living apartments on the six standard floor levels; two apartments per storey. Porter's house in the attic. As the foundations are in the sand, and the building is exposed to strong coastal winds, the structural design has, as interesting features, the foundation ribbed slab and the transversal portal frames, which are W shaped on the ground level. This arrangement makes the edifice look lighter and it acquires a more dynamic plasticity.En la Costa del Sol de Almería y a muy pocos metros de la orilla del mar, se ha construido este edificio de apartamentos. Su programa es el siguiente: casetas de baño y sala de fiestas, en sótano; restaurante-bar, en planta baja; doce viviendas, en las seis plantas tipo, con dos viviendas por planta; y vivienda del portero en ático. Cimentado sobre arena y expuesto a los fuertes vientos que azotan la costa, la solución estructural ofrece el interés de su tipo de cimentación por placa nervada, y de sus pórticos transversales que en planta baja adoptan forma de W, con lo que el edificio adquiere un aspecto de mayor ligereza y de dinamismo plástico.

    Costa Rica has a diversity of volcanic crater lakes that can be classified into two groups: hot and cold lakes. The country contains at least 5% of the world's hot lakes. Costa Rica has 2 hot hyperacidic lakes, both of them on active volcanoes, the Rincón de la Vieja (38.0°C, pH = 0 - 1) and the Poás Laguna Caliente (36.1°C - 56°C, pH = 0.55 - 0.74), nowadays the Poás hot lake is the most active crater lake in the world, with more than 200 eruptions only on 2010. One of the most studied cold crater lakes is Irazú (13°C, pH = 3.5), that used to contain bubbling and clear areas of upwelling involving CO2 liberation and subaqueous fumaroles with temperatures up to 50°C, but since 2005 the lake presents an important descend until April 2010 when it disappeared. On February 9, 2003, Irazú's lake underwent a drastic change of color, from clear green to mustard with reddish loops, similar to the color of the waters of Lake Nyos after the gas burst of August 1986. Other studied cold lakes include Botos, Chato, and Tenorio, all at the summit of Quaternary volcanoes as well as Barva and Danta, located in recent pyroclastic cones. Some cold lakes are located in Holocene maar-type explosion craters, among them are Congo, Bosque Alegre, Hule, and Río Cuarto. These last two have undergone repeated rapid reddish color changes over the last 10 years, in association with fish kills and the liberation of apparently sulfurous scents. On March 2010, University of Costa Rica was the host of the 7th Workshop on Volcanic Lakes, part of the Commission of Volcanic Lakes of the IAVCEI, 51 participants from 14 countries attended the workshop; they presented 27 talks and 17 posters, also they visited and sample 4 of the lakes mentioned above (Botos, Irazú, Río Cuarto and Hule).

    Rickettsia felis is an emerging human pathogen associated primarily with the cat flea Ctenocephalides felis. In this study, we investigated the presence of Rickettsia felis in C. felis from Guatemala and Costa Rica. Ctenocephalides felis were collected directly from dogs and cats, and analyzed by polymerase chain reaction for Rickettsia-specific fragments of 17-kDa protein, OmpA, and citrate synthase genes. Rickettsia DNA was detected in 64% (55 of 86) and 58% (47 of 81) of flea pools in Guatemala and Costa Rica, respectively. Sequencing of gltA fragments identified R. felis genotype URRWXCal2 in samples from both countries, and genotype Rf2125 in Costa Rica. This is the first report of R. felis in Guatemala and of genotype Rf2125 in Costa Rica. The extensive presence of this pathogen in countries of Central America stresses the need for increased awareness and diagnosis. PMID:22665618

    The hydrocarbon exploration data base in Costa Rica, gathered through various recent periods, indicates promising hydrocarbon potential in the country. During 1980--94, Recope SA, the state petroleum company, performed a series of studies to evaluate the petroleum potential in the whole Costa Rican territory. As a first step, the information compiled during previous studies was re-evaluated, and later new information was collected with the aid of foreign governments and cooperating institutions. A new exploratory era began with the Costa Rican Congress` approval in 1994 of the Hydrocarbon Law, which allows private companies to participate in hydrocarbon exploration and exploitation. This article brings together some highlights about Costa Rica oil potential and gives basic information on future hydrocarbon exploration and development under the regulation of the new Hydrocarbon Law.

    2001-12-01

    The bathymetry of Coco's Island (UNESCO Natural and Cultural World Patrimony), located approximately 500 km from the Pacific coast of Costa Rica, is not well known. It has a high marine biodiversity and also represents a meeting site for many species traveling throughout the Pacific Ocean. The insular shelf is irregular in extension and also in bathymetric features. The northeast limit is defined by the 109.8-128.1 m contours (60-70 fathoms) while the 183 m contour (100 fathoms) practically defines the rest of the island, from which the depth gradient is steep. The maximum extension is to the northeast with a longitude of 13 km. In this context the present limits of the marine park (5 km), are insufficient to protect the whole insular shelf. Current regulation should be modified to prevent fishing activities less than 15 km from the Island.

    Full Text Available Retos para la agricultura en Costa Rica es un análisis crítico del desarrollo agrícola de Costa Rica de los últimos 25 años. La diversificación agrícola que promovió Costa Rica en la década de los ochenta, permitió ampliar la oferta exportable y reducir la vulnerabilidad de la dependencia económica de productos tradicionales, como café y banano. Los retos de la economía global y el establecimiento de tratados comerciales con muchos países, hacen necesario que el país promueva en el sector agrícola la exportación con mayor valor agregado, para lo cual es necesario una modernización y reconversión productiva, ya que el modelo actual está agotado. Debemos mejorar sustancialmente los bienes y servicios que ofrecemos; para este propósito, algunos aspectos como la imagen de marca del país con tradición democrática, respeto a los derechos laborales, así como las buenas prácticas de manejo ambiental, deben publicitarse. Como una herramienta clave para la incorporación de mayor valor agregado a nuestra producción agrícola, debemos promover la inversión en investigación y desarrollo, que históricamente ha sido escasa (0,4% del PIB. En vista de que el Estado Costarricense ha demostrado una incapacidad crónica para impulsar la ciencia y la tecnología como una herramienta para nuestro desarrollo, se propone un estímulo a la inversión privada y el fortalecimiento de una alianza con el Estado y las universidades. Se analiza la conveniencia del fortalecimiento de la autosuficiencia alimentaria y de que las empresas pequeñas y medianas jueguen un papel más activo en la agro-exportación. Respecto a los tratados comerciales que se han venido negociando, se considera la conveniencia para el país, ya que son instrumentos para integrar nuestro quehacer económico a nivel mundial, y nuestro deber es el de luchar para que el sector agropecuario tenga oportunidad de subsistir competitivamente según esas nuevas reglas y

  16. Polio Crisis in Costa Rica: Lessons Learned and Achievements

    Full Text Available This presentation shows some of the consequences of the polio crisis in Costa Rica during the 1950’s, in order to preserve certain attitudes of Costa Ricans back then that are worth remembering: simplicity, solidarity and gratefulness. Hand in hand with highly service-oriented men and women, the country overcame the crisis and built one of the most iconic hospitals in Costa Rica: the National Children’s Hospital. It is worth rescuing the lessons learned and applying them to current times. This historical text was created based on the stories told by people who lived during the times of the crisis, on a 1956 notebook, on documents from the National Archive and the National Health and Social Security Library (BINASSS, for its name in Spanish, the Costa Rican Social Security System (CCSS, for its name in Spanish, Dr. Rodolfo Álvaro Murillo, and San Juan de Dios Hospital.  National and international newspapers were also reviewed. The consulted material confirms how the work of Costa Ricans, led by committed and service-oriented individuals, allowed for the construction of the National Children’s Hospital to take place -an institution that has served the Costa Rican people for fifty years. Costa Ricans also succeeded in eradicating polio long before several other countries around the world. The reactions of people in the 1950’s are lessons of solidarity and humanity that should not be forgotten; they should be remembered in order to value team work over individual work and make sure, no matter what our role in society is, to always stand by common well-being, as mid-century Costa Ricans did by overcoming their personal limitations and acting for the benefit of society.

    A study of external natural radiation, cosmic and terrestrial components, was carried out with in situ measurements using NaI scintillation counters while driving along the roads in Costa Rica for the period July 2003-July 2005. The geographical distribution of the terrestrial air-absorbed dose rates and the total effective dose rates (including cosmic) are represented on contour maps. Information on the population density of the country permitted the calculation of the per capita doses. The average effective dose for the total cosmic component was 46.88{+-}18.06 nSv h{sup -1} and the average air-absorbed dose for the terrestrial component was 29.52{+-}14.46 nGy h{sup -1}. The average total effective dose rate (cosmic plus terrestrial components) was 0.60{+-}0.18 mSv per year. The effective dose rate per capita was found to be 83.97 nSv h{sup -1} which gives an annual dose of 0.74 mSv. Assuming the world average for the internal radiation component, the natural radiation dose for Costa Rica will be 2.29 mSv annually.

    Full Text Available Desde 1979 se han reportado florecimientos de especies de microalgas nocivas (FAN en la costa Pacífica de Costa Rica, reconociéndose hasta el 2005 al menos 13 taxa de dinoflagelados. En años recientes estos fenómenos se han intensificado tanto espacial como temporalmente, produciéndose discoloraciones casi ininterrumpidas que se extienden por toda la costa produciendo mortalidad de peces y fetidez en el agua. Tales FAN masivos se iniciaron con Pyrodinium bahamense en el 2000, quien perduró por más de un año y en el cual se observaron morfotipos correspondientes a las dos variedades de la especie, coexistiendo junto a Gymnodinium catenatum y ocasionando serios casos de Intoxicación Paralizante por Consumo de Mariscos (IPM. Posteriormente, de septiembre del 2003 hasta junio del 2004, Cochlodinium cf. polykrikoides produjo discoloraciones en toda la costa Pacífica, seguidas por manchas extensas de Akasiwo sanguinea y Gymnodinium instriatum. El evento más reciente se observó en junio del 2005 cuando Alexandrium monilatum produjo extensas discoloraciones con cadenas formadas por más de 100 células. Los FAN de dinoflagelados ahora son comunes en las costas de Costa Rica, posiblemente como resultado de las condiciones ambientales actuales que favorecen la proliferación masiva de especies invasivas (agresivas, las cuales incluso pueden afectar otros sitios del Pacífico americano como es el caso de P. bahamense var. compressum que puede desplazarse hasta México, a lo largo de la costa del Pacífico centroamericano a través de la Corriente Costera de Costa Rica y la Corriente Occidental Mexicana.Since 1979 has been reported harmful microalgae blooms (HAB on the Pacific coast of Costa Rica, it was identified until 2005 at least 13 taxa of dinoflagellates.

Una buena parte de la atención se pone en el ritmo de la fecundidad en las etapas umbral, temprana y tardía de la disminución de la fecundidad que este país experimentó durante los años sesenta y principios de los setenta. Los resultados muestran bastante similitud en el tempo de la reproducción en los diferentes niveles paridez y áreas geográficas. Sin embargo, un análisis de las variables del entorno que afectan espaciamiento de los nacimientos muestra diferencias entre las zonas urbanas y rurales. Por último, se postula que el reciente estancamiento en las tasas de período puede ser una consecuencia de los cambios en el tempo de construcción de la familia, con mujeres de baja paridez que postergan los nacimientos, lo que contrarresta las tendencias de descenso que generan las mujeres de mayor paridez quienes aún pueden estar restringiendo su reproducción.ABSTRACTThis paper uses data from the Latin American Comparative Fertility Surveys as well as from the World Fertility Survey to study trends and differentials in birthspacing among ever married women in Costa Rica during the period 1945-1974.

Are obtained in the zero and first approximation the equations of the phase error for the Costas circuit. The simulation in MatLab environment of phase error introduced by the Costas circuit in the first approximation and the graphs of this error is carried out. On the basis of mathematical model, by the phase error counts were obtained graphs of probability density functions of the signal errors introduced by the model. A simulation model of the Costas circuit in the Simulink environment is given. In the simulation model, by the phase error counts in MatLab, were obtained graphs of probability density functions of the signal error due to the simulation model. The comparison of the obtained results of the Costas circuit analysis obtained by mathematical modeling of the phase error equation in the first approximation with simulation results in Simulink environment shows that the results of mathematical modeling rather accurately coincide with the simulation results. On the basis of simulation were obtained the graphs of the average time before mistracking for various values of the interference to signal ratio

    Full Text Available This paper intends to report on the beginning of the publications of Newton da Costa outside Brazil. Two mathematicians played an important role in this beginning: Marcel Guillaume from the University of Clermont-Ferrand and Paul Dedecker from the Universities of Lille and Liège. At the same time we recall the role played by Newton da Costa and Jayme Machado Cardoso in the development of what we call here the School of Curitiba [Escola de Curitiba]. Paraconsistent logic was initiated in this school under the influence of Newton da Costa. As another contribution of this school we mention the development of the theory of quasigroups; Jayme Machado Cardoso's name has been given, by Sade, to some particular objects which are now called Cardoso quasigroups.

    Full Text Available Track analysis and Parsimony analysis of endemicity (PAE were performed to analyze the distribution pattern of Costa Rican freshwater fishes. A basic matrix (presence/absence was prepared using the distribution of 77 freshwater fish. The data were analyzed with CLIQUE software in order to find generalized tracks (cliques. Data also were analyzed with the software NONA and Winclada version 1.00.08 in order to perform the Parsimony Analysis of Endemicity (PAE. Fourteen equally probable cliques were found with 31 species in each and the intersection of the amount was selected as a generalized track dividing the country in two main zones: Atlantic slope from Matina to Lake Nicaragua and Pacific slope from the Coto River to the basin of the Tempisque River connected with some branches oriented to the central part of the country. PAE analysis found ten cladogram areas (72 steps, CI=0.45, RI=0.64, using the "strict consensus option" two grouping zones were identified: Atlantic slope and Pacific slope. Both PAE and Track Analysis show the division of the two slopes and the orientation of the generalized track suggests new biogeographical evidence on the influence of both old and new southern elements to explain the migrations of freshwater fish into Central America during two different geological events.

    D'Alonzo, Karen T; Cortese, Lauren B

    2007-07-01

    A comparative survey design was used to examine habitual and incidental physical activity among native Costa Rican (CR) and Costa Rican American (CRA) adolescent girls. The purposive sample included 17 girls (ages 12-19 years) living in Limon, Costa Rica (n = 11), and the metropolitan New York/New Jersey area (n = 6). Participants in the CR group had significantly higher levels of habitual (p = .04), incidental (p = .02), and combined (p = .03) physical activity as compared with those on the CRA group. Dance was a preferred form of activity for both groups. The relationship between habitual and incidental physical activity was not significant, underscoring the need to address both variables in assessment of total physical activity. The findings suggest a need to prioritize the promotion of physical activity among immigrant teenage girls using culturally valued methods.

La CCSS se financia con contribuciones de los afiliados, los empleadores y el Estado, y administra tres regímenes: el seguro de enfermedad y maternidad, el seguro de invalidez, vejez y muerte, y el régimen no contributivo. La CCSS presta servicios en sus propias instalaciones o contrata prestadores del sector privado con los que establece contratos denominados "compromisos de gestión". El sector privado comprende una amplia red de prestadores que ofrecen servicios ambulatorios y de especialidad con fines lucrativos. Estos servicios se financian sobre todo con pagos de bolsillo, pero también con primas de seguros privados. El Ministerio de Salud es el rector del sistema y como tal cumple con funciones de dirección política, regulación sanitaria, direccionamiento de la investigación y desarrollo tecnológico.

Objective: To describe the operations, activities, and resources of the DICs and the DISs affiliated with public institutions of Costa Rica, and their adjustment to the provisions set forth by the PAHO. Methods: Descriptive study conducted in May 2003. The officers in charge of each of the seven public DICs or DISs in Costa Rica were interviewed, and inquiries were made regarding aspects of the structure and process of their centers. Results: In Costa Rica there are seven public drug information units, that is, four DICs and three DISs. One of the DICs is located in this university, and the remaining six centers and services are in located in hospitals. Five of the centers do not have the primary sources required by the PAHO. Fifteen out of the 36 tertiary sources recommended are not available in any of the centers. 100% of the information units carry out four main activities: answering inquiries from the hospital community, answering inquiries from users outside the hospital, implementing education programs for patients and risk groups, and rotation programs for student training. Conclusions: The activities developed by the DISs and the DICs in Costa Rica are similar to each other; they respond not only to the PAHO’s guidelines, but they also have similarities with the activities and operations of other DICs worldwide. Primary, secondary, and tertiary bibliographical support must be strengthened.

Los datos fueron clasificados y analizados de acuerdo con la región geográfica de origen de los individuos. Se estimaron las frecuencias génicas y su bondad de ajuste al equilibrio de Hardy-Weinberg mediante el método de máxima verosimilitud. Se observó la existencia de una estructuración geográfica en la población de Costa Rica. Todas las regiones de Costa Rica presentan valores de heterocigosidad mucho mayores a los observados en los pueblos indígenas costarricenses, pero semejantes o ligeramente mayores a los encontrados en poblaciones de España. El análisis de distancias génicas evidenció que las regiones de Costa Rica se agrupan próximas entre sí, en posiciones intermedias entre las amerindias y las de España, hecho que es coherente con el planteamiento que atribuye un origen mestizo a la población general de Costa Rica. Además, los datos contradicen la idea de que la región Central tiene una población radicalmente diferente a las demás regiones del país. Estos marcadores revelan pobres valores de probabilidad de exclusión forense y de paternidad, lo que confirma la importancia de su reemplazo por marcadores de ADN en los esquemas de identificación humana de los sistemas de investigación judicial.

Entre el 24 de Marzo y el 10 de Abril del 2006, hubo una serie de erupciones que, la administración del parque prohibiera primero y restringiera después el acceso del número de visitantes al PNVP por tres semanas. El estudio examina el impacto de tales restricciones en las comunidades de Poasito y Fraijanes, las comunidades ubicadas en la entrada del parque, las cuales dependen económicamente de los gastos de los turistas que visitan el parque para sobrevivir. El estudio examina además el impacto social, de la falta información durante este tiempo en la opinión de las comunidades y los negocios sobre la gestión del desastre por parte de la administración del parque. Se encontró que para mejorar los planes para el manejo de esta clase de desastres, el parque y la comunidad deben mejorar la comunicación entre ambos, y la participación y coordinación de actividades. Para disminuir los riesgos de desastres físicos y económicos, la comunidad tiene que organizarse para pedir y obtener más información sobre las crisis generada por futuras erupciones y diversificar el tipo de turismo de que depende. La administración del Parque Nacional Volcán Poás debería iniciar actividades que ayuden el mejoramiento de la capacidad de participar de las comunidades en las actividades que el parque realiza en épocas de crisis, también debería incluir las necesidades informativas de la comunidad y de los negocios en su plan de gestión de desastres.

The genetics and the physiopathological aspects of the disease clarified until know, are here summarized. More than twenty genes and ten additional loci have been related with HMSN. These findings contribute to understand the metabolism of peripheral nerves and give the basis for molecular diagnostics and future therapy. Several Costa Rican families with CMT have been identified, specially with axonal forms. Two families present mutations in the myelin protein zero gene (MPZ. In addition, linkage have been found between the disease and locus 19q13.3 in an extended family, and a mutation segregating with the disease is present in a candidate gene of the critical interval.

    Full Text Available The present paper analyzes the definition of the concept of universal accessibility, considering the current state of accessibility in Costa Rica, especially in the field of technology. It aims to raise awareness and provide guidance to the public reader, pointing out some of the myths present within the definition of accessibility, taking into account different perspectives from other studies, and exemplifying situations related to web accessibility, mainly. We analyze the data generated by the National Statistics and Census Institute (INEC on the population with disabilities in Costa Rica. This analysis is done through statistical information provided by the past censuses carried out during the decades of the present century, considering the importance of improving ICTs for people who have some type of disability, caused by nature or by time. The paper reviews different projects that, at present, are being promoted in ICTs and are considered important advances to improve the conditions of people with disabilities.  It promotes the inherent need to work on the development of ICTs in Costa Rica from different frameworks. In the political and legal frameworks, it identifies the need to extend the rules promoting the laws in favor of disability in the country. In conclusion, the article analyzes that Costa Rica could become one of the first countries in Central America and the Caribbean covering the needs of people with disabilities, through the strengthening and recognition of ICTs that give added value to build a universal accessibility.

    Full Text Available A crescente carência de heparina (HEP motiva a busca por fontes alternativas de novos anticoagulantes naturais. Objetivou-se avaliar a atividade anticoagulante dos polissacarídeos sulfatados (PS isolados de uma rodofícea do gênero Halymenia, nativa do litoral cearense, Brasil. Os PS totais foram obtidos por digestões consecutivas com papaína em tampão acetato de sódio 0,1 M (pH 5,0, contendo cisteína 5 mM e EDTA 5 mM, seguidas por cromatografia de troca iônica em coluna de DEAE-celulose. As frações obtidas foram concentradas por liofilização e submetidas à eletroforese em gel de agarose a 0,5%. Os ensaios anticoagulantes foram realizados pelo tempo de tromboplastina parcial ativada (TTPA, usando-se plasma de coelho e uma curva padrão de HEP (100 UI MG-1. As extrações (53,96% mostraram diferenças marcantes durante o fracionamento e no grau de resolução dos PS. A espécie apresentou PS com atividade anticoagulante superior a HEP. O TTPA das frações modificou-se acentuadamente entre as extrações, expressando-se de maneira dose-dependente e sofrendo um acréscimo de 110,40 (1ª extração para 143,10 UI MG-1 (3ª extração. Os resultados sugerem que a atividade anticoagulante dos PS isolados de Halymenia sp. foi promovida pela inibição da via intrínseca e/ou comum da cascata de coagulação. As modificações no TTPA possivelmente serão elucidadas pelos mecanismos de ação envolvidos na coagulação e caracterização estrutural desses compostos. Portanto, a rodofícea Halymenia sp. é uma boa fonte de heparinoides e sugerem-se estudos relacionados ao cultivo da espécie, em proteção aos bancos de algas.The increasing demand for heparin (HEP has led to a search for alternative sources of natural anticoagulants.

    Full Text Available La estricnina es un alcaloide de origen vegetal, de efecto convulsivante el cual ha sido usado en Costa Rica como plaguicida y rodenticida y también como adulterante de drogas de abuso. Su utilización terapéutica ha sido rechazada. La intoxicación por este tóxico es rara debido al uso actualmente restringido en Costa Rica para la eliminación de perros callejeros por personal de salud. La sintomatología, primordialmente neurológica y cardiorrespiratoria, es de diagnostico clínico y de laboratorio, según esta revisión e la literatura reciente. Los principales hallazgos postmortem son rigidez cadavérica precoz e intensa y síndrome asfíctico. Los registros de la Sección de Patología Forense del Organismo de Investigación Judicial de Costa Rica presentan desde 1990, únicamente dos casos de muerte por intoxicación con estricnina. Se trata de mujeres, que presentaron la rigidez anotada, corroborándose por la escena de muerte y en el laboratorio. La baja frecuencia se debe a la dificultad para conseguir la estricnina.Strychinine is an alcaloid of plant origin and convulsive effect which has beenused in Costa Rica as a pesticide androdenticide, as well as adulterant in abused drugs.

    Full Text Available Costa Rica is stuck in a transition phase between an efficiency-based economy and an innovation-based economy and is not promoting the necessary entrepreneurial conditions that would lead to the required transformation.  Meanwhile, other countries in the region are in a better position to encourage entrepreneurship. In this situation, it is important to ask which are the conditions regarding entrepreneurship in Costa Rica that could improve the transition to an innovation-based economy. To improve this situation, the country must develop an inter-institutional support program that attracts direct foreign investment and linkages between businesses, improve human capital, provide training, incubation and funding, and have better articulation of public policy.

  20. Socioeconomic development, health interventions and mortality decline in Costa Rica.

    Science.gov (United States)

    Rosero-Bixby, L

    1991-01-01

    Costa Rica, whose life expectancy was 74 years by 1985, has reached a health level comparable to a developed country. The health achievements of this country are product of political and socioeconomic circumstances as well as of right public health policies. Until about 1970 the features of Costa Rica mortality, although somewhat better than the Latin American average, evolved in a similar way to the rest of the region. In particular, the decades of 1940s and 1950s saw dramatic improvements in life expectancy, thanks mainly to the import of low-cost, high-effectiveness health technologies. In the 1970s, however, Costa Rica departed from a regional pattern of stagnation and managed to close the gap with developed countries in terms of mortality levels. A dramatic decline in the infant mortality rate from 60 to 19 per 1,000 took place in this decade. The main determinants of this breakthrough were health interventions, notably a primary health care program, even though favorable socioeconomic conditions and a reduced fertility also played a role. Ecological data and other evidence suggest that up to three fourths of the mortality decline was accounted for contemporary improvements in public health services, with about 40 percent attributable to primary health care interventions. Furthermore, by targeting interventions on the less privileged population, these interventions had the merit of reducing geographic and socioeconomic differentials in child mortality.

  20. Costa Rica's 'White legend': how racial narratives undermine its health care system.

    Science.gov (United States)

    Campo-Engelstein, Lisa; Meagher, Karen

    2011-08-01

    A dominant cultural narrative within Costa Rica describes Costa Ricans not only as different from their Central American neighbours, but it also exalts them as better: specifically, as more white, peaceful, egalitarian and democratic. This notion of Costa Rican exceptionalism played a key role in the creation of their health care system, which is based on the four core principles of equity, universality, solidarity and obligation. While the political justification and design of the current health care system does, in part, realize this ideal, we argue that the narrative of Costa Rican exceptionalism prevents the full actualization of these principles by marginalizing and excluding disadvantaged groups, especially indigenous and black citizens and the substantial Nicaraguan minority. We offer three suggestions to mitigate the self-undermining effects of the dominant national narrative: 1) encouragement and development of counternarratives; 2) support of an emerging field of Costa Rican bioethics; and 3) decoupling health and national successes.

    Nesse trabalho procurou-se observar o efeito de diversas substâncias nitrogenadas sobre o crescimento miceliano, esporulação e aspectos morfológicos das colônias do fungo Colletotrichum gossypii South. var. cephalosporoides Costa em substrato sólido. Usou-se um substrato sintético como meio-básico e a este se adicionou peptona, metionina, asparagina, nitrato de sódio ou salicilato de amônia, conforme o tratamento. A testemunha não recebeu qualquer fonte de nitrogênio. Concluiu-se que a peptona foi o melhor tratamento para esporulação e crescimento miceliano, seguindo-se a asparagina que foi eficiente na indução da esporulação. O salicilato de amônia exerceu efeito inibidor do crescimento vegetativo e da esporulação do fungo. Para produção de inóculo, a curto prazo, recomenda-se o uso da peptona como fonte de nitrogênio. Foram observadas diferenças na pigmentação, bordos e densidade das colônias. A esporulação, embora abundante em substratos contendo peptona e asparagina, ocorreu em forma de verdadeiras massas localizadas de conídios na primeira, e como conídios dispersos na segunda.

    An improved scalar Costa scheme (SCS) was proposed by using improved Watson perceptual model to adaptively decide quantization step size and scaling factor. The improved scheme equals to embed hiding data based on an actual image. In order to withstand amplitude scaling attack, the Watson perceptual model was redefined, and the improved scheme using the new definition can insure quantization step size in decoder that is proportional to amplitude scaling attack factor. The performance of the improved scheme outperforms that of SCS with fixed quantization step size. The improved scheme combines information theory and visual model.

La baja diversidad y la baja cobertura coralina de varios sitios del parque se atribuyen al impacto del fenómeno de El Niño en los últimos años, a la sedimentación y a la dilución de las aguas en época de lluvias. Se sugiere la necesidad de realizar un monitoreo a largo plazo sobre estos ecosistemas y determinar futuras estrategias de manejo y conservación.

    Full Text Available Global catches of marine fishery resources declined during the last decades; however, there has been a trend of increasing exploitation of deepwater resources that are especially vulnerable to depletion. Such a tendency was noticeable in Pacific Latin América, too. In Costa Rica, the vast majority of the commercial fishing activities are concentrated on the Pacific coast. The target species for the deepwater fishery in Costa Rica are the two pandalids Heterocarpus affinis and H. vicarius as well as Solenocera agassizii, the latter one being the most important in terms of annual landings. Here we compile the information available from Costa Rica about each of the three target species. Furthermore, we describe research activities related to the Costa Rican deepwater resources and present available data about by-catch and discards in this fishery. Finally, the current situation of the administration and management of these resources in Costa Rica is described. Strengthening collaboration between governmental agencies, the fishery sector, non-governmental organizations, and the academic sector is recommended to avoid an uncontrolled overfishing of these valuable deepwater resources along the Pacific coast of Costa Rica.Las capturas globales de los recursos marinos pesqueros disminuyeron durante las últimas décadas. Sin embargo, se ha observado una tendencia de aumento en la explotación de los recursos de aguas profundas, los cuales son especialmente vulnerables a la extracción. Esta tendencia ha sido notable también en la pesca a lo largo del Pacífico de Latino América. En Costa Rica, la mayoría de las actividades pesqueras comerciales se concentran en la costa del Pacífico. Las especies objetivo de la pesca de aguas profundas en Costa Rica son los dos pandálidos Heterocarpus affinis y H vicarius así como Solenocera agassizii, siendo esta última la más importante respecto a las capturas anuales.

    Full Text Available Most of human aggressive behavior occurs in the context of a romantic relationship. Adolescents are not an exception: research show a significant prevalence of dating violence, revealing the need for further study, especially in Latin America, given the lack of research on this topic. This study aims at strengthening knowledge about aggressive behavior in adolescent dating relationships in Costa Rica, taking into account different aggressive behaviors, not only physical or sexual abuse; differences by gender are also analyzed. Based on an ex post facto design, a standardized instrument was used to measure five types of aggressive behavior (i.e., verbal-emotional, physical, sexual, relational and threats in a sample of 468 adolescents from Heredia (Costa Rica. Results show that most participants had committed or suffered aggressions in dating relationships, especially verbal-emotional or both verbal-emotional and sexual abuse, but the mean frequency of reported aggression was low; some significant intersex differences were also found. Results obtained indicate that adolescents have difficulties to deal with conflicts in their romantic relationship; thus this problem needs to be addressed holistically in order to increase the impact of prevention programs for youth.

    The introduction to this report of a study that examines the potential environmental impacts of labor force growth (LFG) in Costa Rica under LFG scenarios notes that LFG is an economically critical aspect of population growth that can affect the environment by expanding the economy's production possibilities frontier and/or by increasing consumption. The introduction also explains why Costa Rica is ideal for this study and identifies the study as unique because it constructs a computable general equilibrium (CGE) model using 10 environmental indicators and because it models uncertainty regarding the values of the economic parameters. The report continues by reviewing the literature linking population and environmental issues; detailing the CGE model; discussing the 10 environmental indicators (deforestation, erosion, pesticide use, overfishing, hazardous wastes, inorganic wastes, organic wastes, greenhouse gas emissions, air pollution, and water/sewer usage) used in the model; and explaining the method used to simulate the impacts of LFG. The major conclusions that emerged from the results of this study are that 1) the economy-wide impacts of LFG (and, thus, population growth) on the environment are important and vary significantly according to the amounts of physical and human capital present in the labor force and 2) the impacts of LFG vary substantially among environmental indicators.

    Sharks are highly vulnerable to intense and prolonged fishery extraction. This article analyzes the data on shark landings from the artisan fishing fleet on Costa Rica's Pacific coast between 1988 and 1997. The data come from an invoicing system administered by the Costa Rican Fisheries Institute (Instituto Costarricense de la Pesca y Acuacultura, INCOPESCA). Pacific coast shark fishing during the period under study represented approximately 20% of the total national fisheries volume. According to data from the invoicing system, the Northern Pacific region was the most productive, reporting 58% of the shark catch nationwide. Within this region, shark fishing in Papagayo Gulf represented 91% and 53% of the landings by fishery region and nationwide, respectively. The mid-sized and advanced (length of boat > 10 meters) artisan fishing fleets reported 96% of the shark catches in the zone. The study of shark fisheries in the Papagayo Gulf zone is crucial for an understanding of fishery dynamics for this resource at the national level. A monthly chronological series was constructed with the landings in the Papagayo Gulf zone, and a Univariate Box-Jenkins (UBJ) Model was estimated for first-order moving averages MA(1) with a seasonal component of the Yt = lamda(t-1) + gammaS12 + a(t) type.

    The CAREX data system converts national workforce volumes and proportions of workers exposed to workplace carcinogens into numbers of exposed in 55 industrial categories. CAREX was adapted for Costa Rica for 27 carcinogens and seven groups of pesticides. Widespread workplace carcinogens in the 1.3 million workforce of Costa Rica are solar radiation (333,000 workers), diesel engine exhaust (278,000), environmental tobacco smoke (71,000), hexavalent chromium compounds (55,000), benzene (52,000), wood dust (32,000), silica dust (27,000), lead and inorganic lead compounds (19,000), and polycyclic aromatic compounds (17,000). The most ubiquitous pesticides were paraquat and diquat (175,000), mancozeb, maneb, and zineb (49,000), chlorothalonil (38,000), benomyl (19,000), and chlorophenoxy herbicides (11,000). Among women, formaldehyde, radon, and methylene chloride overrode pesticides, chromium, wood dust, and silica dust in numbers of exposed. High-risk sectors included agriculture, construction, personal and household services, land and water transport and allied services, pottery and similar industries, woodworks, mining, forestry and logging, fishing, manufacturing of electrical machinery, and bar and restaurant personnel.

    Deforestation and changes in land use have reduced the tropical dry forest to isolated forest patches in northwestern Costa Rica. We examined the effect of patch area and length of the dry season on nestedness of the entire avian community, forest fragment assemblages, and species occupancy across fragments for the entire native avifauna, and for a subset of forest dependent species. Species richness was independent of both fragment area and distance between fragments. Similarity in bird community composition between patches was related to habitat structure; fragments with similar forest structure have more similar avian assemblages. Size of forest patches influenced nestedness of the bird community and species occupancy, but not nestedness of assemblages across patches in northwestern Costa Rican avifauna. Forest dependent species (species that require large tracts of mature forest) and assemblages of these species were nested within patches ordered by a gradient of seasonality, and only occupancy of species was nested by area of patches. Thus, forest patches with a shorter dry season include more forest dependent species. PMID:27672498

    Full Text Available Un sector interesante al que aplicar nuevas categorías de la investigación histórica y social es, sin duda, el de la educación de las mujeres. Maestras, educadoras, pedagogas fueron revolucionarias en diversas épocas de la historia dedicando su existencia a la difusión de conocimientos que pudiesen ser aprovechados por otras mujeres. Para ello fundaron escuelas, escribieron libros y publicaron periódicos. En este sentido las maestras socialistas italianas fueron pioneras al difundir palabras claves como derechos, democracia e igualdad de sueldo. Una figura muy importante fue la maestra antifascista Alda Costa (1876-1944, que luchó contra el militarismo italiano antes de la Primera Guerra Mundial y asumió encargos de gran relevancia en el Partido Socialista. Además fue amiga de Giacomo Matteotti, asesinado por los fascistas en Roma en junio de 1925. Alda Costa fue encarcelada, por su oposición al régimen, y los sufrimientos padecidos precipitaron su muerte.

    We studied the intraspecific territorial defense behavior of wintering Willow Flycatchers (Empidonax traillii) in Costa Rica using a randomized playback experiment that exposed male and female birds to recordings of Willow Flycatcher songs and calls, Lesser Ground Cuckoo (Morococcyx erythropygius) vocalizations, and random noise. Flycatchers of both sexes responded most strongly to simulated conspecific territory intrusion, and the agonistic behaviors that we observed were similar to those seen during natural intraspecific encounters in winter. Both males and females engaged in song and aggressive behaviors in defense of territories, and there was no significant difference between the sexes in scored agonistic responses. The similarity between the sexes in intraspecific territorial defense behaviors and aggressiveness may account for both sexes of flycatchers using the same habitats at our study sites in Costa Rica, and wintering females defending territories against males. The Willow Flycatcher, a sexually monomorphic species, differs in this way from a number of sexually dimorphic passerines, in which behaviorally dominant males occur in more optimal winter habitats. ??

    Mantle peridotite occurs as xenoliths in lavas and bombs at Cerro Mercedes, a Plio-Quaternary potassic alkaline basalt volcano approximately 70 km behind the volcanic front of northern Costa Rica (Tournon and Alvarado, 1997). Mineral exploration led to the first discovery of abundant mantle xenoliths in Central America (Vargas and Alfaro, 1992). The compositions of 71 xenoliths recovered in January 2003 include dunite, harzburgite, lherzolite and olivine websterite. Twenty xenoliths have a diameter of at least 3 cm. The nodules are abundant in basalt outcrops and the rare bombs. In spite of substantial soil development in a rain forest environment, both xenoliths and host lava remain well preserved. Olivine, pyroxenes and spinel are common, plagioclase is present and garnet appears to be absent. There is no obvious shearing or deformation and several pyroxenes are as much as 1 cm in diameter. The mineralogy suggests a relatively shallow upper mantle source, within either the lithosphere or possibly the uppermost asthenosphere. Cerro Mercedes, at latitude 10° 58' N and longitude 82° 21' W, lies along the Rio San Juan, which is locally the border between Nicaragua and Costa Rica, Central America. This location approximately coincides with a boundary between dominantly depleted mantle to the northwest and OIB or Galapagos-like mantle to the southeast. We will use mineralogical data to better define the likely depths and oxidation states of representative nodules and isotopic data to define the type of mantle source.

    Bats are hosts of diverse coronaviruses (CoVs) known to potentially cross the host-species barrier. For analysing coronavirus diversity in a bat species-rich country, a total of 421 anal swabs/faecal samples from Costa Rican bats were screened for CoV RNA-dependent RNA polymerase (RdRp) gene sequences by a pancoronavirus PCR. Six families, 24 genera and 41 species of bats were analysed. The detection rate for CoV was 1%. Individuals (n = 4) from four different species of frugivorous (Artibeus jamaicensis, Carollia perspicillata and Carollia castanea) and nectivorous (Glossophaga soricina) bats were positive for coronavirus-derived nucleic acids. Analysis of 440 nt. RdRp sequences allocated all Costa Rican bat CoVs to the α-CoV group. Several CoVs sequences clustered near previously described CoVs from the same species of bat, but were phylogenetically distant from the human CoV sequences identified to date, suggesting no recent spillover events. The Glossophaga soricina CoV sequence is sufficiently dissimilar (26% homology to the closest known bat CoVs) to represent a unique coronavirus not clustering near other CoVs found in the same bat species so far, implying an even higher CoV diversity than previously suspected.

    Costa Rica has coral communities and reefs on the Caribbean coast and on the Pacific along the coast and off-shore islands. The Southern section of the Caribbean coast has fringing and patch reefs, carbonate banks, and an incipient algal ridge. The Pacific coast has coral communities, reefs and isolated coral colonies. Coral reefs have been seriously impacted in the last 30 years, mainly by sediments (Caribbean coast and some Pacific reefs) and by El Niño warming events (both coasts). Monitoring is being carried out at three sites on each coast. Both coasts suffered significant reductions in live coral cover in the 1980's, but coral cover is now increasing in most sites. The government of Costa Rica is aware of the importance of coral reefs and marine environments in general, and in recent years decrees have been implemented (or are in the process of approval) to protect them, but limited resources endanger their proper management and conservation, including proper outreach to reef users and the general public.

    Subduction zones are characterized by the largest thrust earthquakes, as quantified by both rupture area and seismic moment release. Offshore Costa Rica, the oceanic Cocos Plate subducts under the Caribbean plate forming the southern end of the Middle America trench. A high convergence rate and almost complete subduction of incoming sediments make the Costa Rica convergent margin an extremely dynamic environment. The Costa Rica Seismogenesis Project (CRISP) is designed to understand the processes that control nucleation and seismic rupture of large earthquakes at erosional subduction zones. Site U1414 of IODP Exp.344 was drilled to investigate the material from the incoming Cocos Plate. A key parameter of incoming plate is fluid content and release because it impacts deformation within the subduction complex. The deposition, compaction and diagenesis of sedimentary rocks control the distribution of fluids, fluid pressures and fluid flow patterns within subduction zones. We therefore decided to characterize sediment composition and quantify the different types of water at Site U1414. Mineralogical investigations were performed using optical and electronic microscope observations, X Ray Diffraction (on bulk and clay fractions), Cation Exchange Capacity measurements, carbon analyses (to determine carbonate contents), and sequenced extractions in NaOH (to quantify the biogenic opal content). Fluid characteristics were approached by thermal gravimetric analyses. The entire sedimentary sequence was recovered at Site U1414 and can be divided into three major sedimentary units. The first one is a hemipelagic silty clay to clay with a gradual increase of calcareous nannofossils. The dominant mineral is smectite associated in the clay fractions with kaolinite and zeolites. Small amounts of biogenic opal have been analyzed. Other minerals like quartz, feldspar and calcite are also present. The second unit is composed of nannofossil-rich calcareous ooze.

    Full Text Available La trata de personas con fines de explotación sexual comercial es una problemática solapada en Costa Rica. Resulta necesario conocer este fenómeno, puesto que cada día más ciudadanos son atrapados y sometidos a una forma de esclavitud, que denigra su integridad física, psicológica, social y espiritual. A partir de las experiencias vividas como profesional en una organización sin fines de lucro (ONG con un programa para esta población, hizo evidente el desconocimiento y los excesivos prejuicios sobre las víctimas en la sociedad. Se explora el hecho de que la información sobre este fenómeno en Costa Rica es escasa y el abordaje psicológico lo es aún más. La investigación tiene sus bases en la metodología cualitativa descriptiva; se propone un diseño fenomenológico que parte de la teoría humanista del Análisis Transaccional de Berne (1976 para efectuar estudio múltiple de casos. La muestra estuvo constituida por un grupo de cinco mujeres, que se encontraron en proceso de restauración en la ONG bajo las categorías de análisis “Trata de personas con fines de explotación sexual comercial nacional” (dentro de Costa Rica, “Avasallamientos” y “Desarrollo personal”. Los resultados identificaron avasallamientos, a los que fueron sometidas las mujeres de esta muestra, antes, durante y después de ser captadas en la trata. Asimismo, se analiza cómo el desarrollo de las mujeres víctimas de trata en este estudio se ve obstaculizado por dichos avasallamientos y cómo algunas lograron obtener el crecimiento personal a pesar de lo sucedido.

    Full Text Available Este documento ilustra un enfoque económico a la comprensión de la industria de turismo de cruceros como impulsora del desarrollo económico en Costa Rica. El objetivo es describir el papel y las actividades de la industria de cruceros e identificar fuentes de costo y beneficio económico, a fin de que se puedan tomar decisiones locales de política con más información sobre el turismo de cruceros. Por ejemplo, nuestro análisis indica que la industria de turismo de cruceros compite con la industria de despacho de carga por espacio portuario a un significativo costo para los puertos de Costa Rica: la cantidad de dinero inyectada a la economía local por turista de crucero es sustancialmente más baja que para otros tipos de turismo. Los cruceros de turismo compran relativamente pocos suministros en Costa Rica y generan una gran cantidad de desechos producidos por las personas así como contaminación de agua y aire, lo que puede crear un serio peligro para la salud y costos de limpieza que no son proporcionales con otros tipos de desarrollo turístico de los que dispone el país. Quizás los encargados de tomar decisiones quieran considerar que la inversión en puertos amistosos con el turismo de crucero podría ser menos eficiente desde una perspectiva nacional que la inversión en infraestructura (por ejemplo, aeropuertos para aumentar tipos más rentables de turismo. Asimismo, quizás los líderes quieran pensar en estimular cruceros más pequeños “de bolsillo” más bien que la actual versión de turismo masivo. Este método debería ser aplicable a comunidades donde el turismo de crucero existe actualmente o se está considerando para incluirlo en la cartera de actividades económicas comunitarias.

    2001-12-01

    This report is part of a series that summarizes the species and localities of Costa Rican marine taxa. A review of the literature on copepods, both pelagic and benthic for the Pacific and Caribbean coast of Costa Rica, includes eighty species. Sixty seven pelagic species have been found, distributed between sixteen calanoid, one cyclopoid, three harparticoid and four poecilostomatoid families. Moreover, thirteen benthonic species distributed into six families, all harparticoids, are reported. Among the pelagic families, Pontellidae has six species, while Paracalanidae and Eucalanidae had five each. Other families, like Calanidae, Pseudodiaptomidae and Acartiidae had four species and most families only one. Forty five species are reported only for the Pacific coast, thirteen for the Caribbean coast, only nine species occurred in both coasts; being a direct consequence of the more intensive research effort in the Pacific. Pelagic copepod biodiversity reflects different oceanographic conditions in both coasts. Typical estuarine species were found in the lower region of the Gulf of Nicoya, while a mixture of estuarine and oceanic species were found in Golfo Dulce. Diversity in the Caribbean, specially at the Cahuita coral reef is lower in comparison with the copepod diversity found in other regions in the Caribbean sea. This may be due to the high sediment resuspension rate characteristic of the Cahuita coral reef, which could affect the reproduction of many holozooplankters, specially copepods. Although sixty seven pelagic copepod species appears to be in low numbers, in terms of specific biodiversity it is as high when compared to numbers found in other tropical areas. Thirteen species are reported in the literature, all harparticoids. Five species, three sub-species and one genera were new to science. Balacopsylla is reported for the first time from a neotropical regions, while the genus Karllangia, represented by two coexisting species in the Caribbean coast

    Full Text Available This observational pilot study was carried out at three sugarcane companies in Costa Rica. Its main objective was to determine the potential for heat stress conditions for workers in one sugarcane-growing region in Costa Rica during the maintenance (non-harvest period.Wet bulb globe temperature (WBGT variables were measured with a heat stress meter and threshold value limits and the Sweat Rate Indexes were calculated for each workplace. It was determined that workers in this study were in heat stress conditions. Costa Rica is likely to experience warmer temperatures and increased heat waves in the coming decades. It is therefore important to take action to decrease current and future heat-related risks for sugarcane workers in both harvest and non-harvest conditions and in all sugarcane growing regions in Costa Rica. It is also necessary to improve guidelines and occupational health standards for protecting worker health and productivity in the tropics.

    The time-space behavior of thermohaline properties of the water masses in the Gulf of Nicoya, a tropical estuary in the Costa Rican Pacific coast, was studied by sampling monthly from April 1992 to April 1993. The saline field has a seasonal maximum during April, a month before the maximum temperature is observed. Minimun values were observed during October and November, in the rainy season. A defined surface saline front is located towards the east of Negritos Islands; it is produced by the interaction of freshwater from the Tarcoles River and the oceanic waters that enter through the occidental coast of the gulf. The vertical distribution of temperature and salinity indicates a gulf whose internal area is highly stratified in the rainy season, and much less stratified, or even well mixed in the dry season. The outer area of the Gulf is stratified throughout the year.

La medida de núcleo inflacionario seleccionada se contrasta con el Índice de Núcleo Inflacionario (INI, indicador de inflación subyacente actualmente utilizado por el Banco Central de Costa Rica (BCCR.El Índice Subyacente de Inflación (ISI, definido como una medida de núcleo inflacionario que excluye un 30,7% del peso total del Índice de Precios al Consumidor (IPC, refleja más fielmente la tendencia subyacente de la inflación y logra capturar el movimiento más permanente del nivel general de precios, aislando las variaciones en precios relativos. Además, el ISI es fácil de calcular e interpretar lo cual ayuda a incrementar la transparencia y credibilidad de la política monetaria. También es un indicador oportuno, aumentando su valor para los que formulan la política monetaria.

    Full Text Available The present document studies the degree of inflation persistence and price stickiness across different categories in the Costa Rican Consumer Price index (CPI, using disaggregate and aggregate data, with a particular focus in the regulated and services prices. We adopt two approaches: The parametric approach is based in an autoregressive process with constant mean, and the structural approach is based on the estimation of the New Keynesian Hybrid Phillips Curve. We use different econometric techniques, as univariate and multivariate time series, and panel data methods. The evidence suggests that changes in prices and services regulated items have higher degrees of persistence in addition to presenting rigidities in the adjustment pattern. Also it was found that using disaggregate data the degree of inflation persistence is lower than the inflation persistence estimation of univariate models with aggregate data, and this tend to reduce excluding the regulated and services products prices.

    Arbutoid mycorrhizas of Comarostaphylis arbutoides (Arbutoidea, Ericaceae) from neotropical montane forests are rarely described. To date, only mycorrhizal associations with the fungal species Leccinum monticola, Leotia lubrica and Sebacina sp. are known from literature. The genus Cortinarius is one of the most species-rich ectomycorrhizal taxa with over 2000 assumed species. In this study, two sites in the Cordillera de Talamanca of Costa Rica were sampled, where Com. arbutoides is endemic and grows together with Quercus costaricensis. Using a combined method of rDNA sequence analysis and morphotyping, 33 sampled mycorrhizal systems of Cortinarius were assigned to the subgenera Dermocybe, Phlegmacium and Telamonia. Specific plant primers were used to identify the host plant. Here, we present the phylogenetic data of all found Cortinarii and describe four of the arbutoid mycorrhizal systems morphologically and anatomically.

    Full Text Available The coccids have different sex-determining mechanisms, including the heterochromatinization haplodiploidy of chromosomes of paternal origin, characteristic of the family Dactylopiidae. The heterochromatinization in coccids seems to be a mechanism by which part of a chromosome, the entire chromosome, or several chromosomes will become genetically inactive during development of the individual. In the first division immediately after fertilization, the chromosomes of embryos appear euchromatic (E; shortly after the blastocyst stage, almost half of the chromosomes become heterochromatic (H in embryos that are destined to be male, while in the female all the chromosomic set remain euchromatic. The objective of this study is to determine the heterochromatinization process in the sex determination of Dactylopius coccus Costa, 1935 embryos. The method used to identify chromosomes has been the conventional 2% lacto-acetic orcein protocol. In D. coccus it was observed that during embryogenesis, heterochromatinization occurs in the set of chromosomes from paternal origin, while those of maternal origin remain euchromatic.

    Full Text Available A total of 98 liverwort species (43 genera, 10 families, 54 moss species (33 genera, 17 families and one species of hornwort have been reported for Cocos Island (5°32’N, 87°04’W, Costa Rica. Over 60% of the bryophytes have a Neotropical or Pantropical distribution, about 10% are Caribbean, and less than 5% are endemic or subendemic. In comparison to the Galapagos Archipelago, Cocos Island harbors a more typical tropical bryoflora with foliose hepatics (e. g. Lejeuneaceae, Lepidoziaceae constituting the bulk of diversity; fewer thallose liverworts and moss taxa as in the Archipelago were found. A richer habitat variety including wet and dry habitats, as well as its bigger area, seem to account for the higher number of bryophyte species in Galapagos Archipelago. Most bryophytes in Cocos Island are corticolous (46%, the remaining are epiphyllous (25%, saxicolous (23% or terrestrial (12%. Bryophyte occurrence in eight plots (10 x 10 m with 20 quadrates (30 x 30 cm were recorded at different habitats and altitudes (0-600 m.

  5. Partitioning of Seismogenic Strain in the Offshore Costa Rica Forearc

    Lewis, J. C.; Bilek, S.

    2002-12-01

    We examine non-recoverable strain in the offshore forearc crust between the Osa and Nicoya Peninsulas of Costa Rica. Treating the crust as a micropolar continuum we use new and published earthquake focal mechanisms to invert for best-fitting partial strain-rate tensors. Our preliminary results for new focal mechanisms west northwest of the Osa Peninsula indicate a shallow northwest-plunging maximum stretching axis and a subvertical minimum stretching axis. This strain geometry suggests thinning of the forearc and extension nearly parallel to the Middle America Trench. The earthquakes used to constrain this deformation geometry occurred at depths less than 5.1 kilometers in hanging wall crust adjacent to substantial topographic relief on the downgoing Cocos plate. To date evidence for trench-parallel stretching has only come from observations of brittle faults in coastal and inland exposures in Miocene sediments and Quaternary fluvial deposits. Our inversions of existing data from southeast of the Nicoya Peninsula yield results that are in accord with previous findings. Here, events ranging in depth between about 12 and 31 kilometers indicate nearly trench-normal shortening and crustal thickening. Earthquakes at similar depths just west northwest of the Osa Peninsula, however, reveal subhorizontal maximum and minimum stretching axes with the former trending south. This strain geometry is consistent with strike slip faulting and suggests partitioning of seismogenic strain with depth in the forearc offshore Osa Peninsula. In total, our findings suggest variations in the 3-dimensional pattern of non-recoverable strain in the Costa Rica forearc. A quantitative description of this sort of variation is necessary in order to better understand geodetic observations, and ultimately, the relation between coupling across the seismogenic zone and forearc strain.

    The Community Development Association of the fishing village of Barra del Colorado populated by Blacks embraced the Conservation Strategy for the Sustainable Development of the Plains Tortuguero covering 419,000 hectares of lowland rain forest and wetlands along the Caribbean cost of northern Costa Rica. In 1985 the government established the Barra del Colorado Wildlife Refuge. The International Union for the Conservation of Nature (IUCN) team visited families and identified community problems. This resulted in the establishment of a communal bank; a community fisherman's association to help obtain a boat and fishing gear; assistance to help villagers obtain title to their land; a feasibility study of a public transport link to the rest of the country; new chairs for the school; and weekly instead of monthly visits by a doctor. The Tortuguero Strategy endeavors to establish 147,000 hectares of conservation area including the Tortuguero National Park. 5000 people live in the buffer zone and 132,000 live in the neighboring western area. The strategy strives to reverse deforestation in the buffer zone by restoring forest cover to 80% of the area by 2000. The Strategy has funded the Union of Small Agricultural Producers of the Atlantic to train people in ecotourism, forestry management, and growing and selling medicinal plants. The IUCN evaluated the environmental impact of expanding banana plantations and recommended ameliorative steps which have not been implemented. The preparation of the Tortuguero Strategy started in 1990 in concert with the Natural Resources Ministry, IUCN, and the European Community. A 1992 draft document based on biophysical, socioeconomic, and legal studies is waiting for official approval. Community strategies have been launched in 2 communities, self-sustaining financing is delayed, and a draft law setting up the conservation area awaits Costa Rican legislative authorization. The strategy is for the long term, but the experience of Barra del

  7. Health care in Costa Rica: boom and crisis.

    1985-01-01

    In 1960-1980 Costa Rica experienced a health boom, achieving significant improvements which moved that country into the number two position in Latin America for indicators such as population coverage, infant mortality, life expectancy and health services. In addition, there was a gradual process of integration of health services. But in the same period, the cost of health care as a percentage of GNP increased almost 5-fold and in 1980 was the fourth highest in the region. The economic crisis of the 1980s aggravated the financial difficulties; to cope with them, the government introduced an austere program to reduce costs and plans to transform the current model of health care into a more efficient one capable of maintaining Costa Rica's high health standards in the future. The paper is divided into five sections: summary of the historical development of health care, and description of its current organization and of its gradual process of integration; estimation of population coverage and its trends, evaluation of inequalities in coverage, and identification of the non-covered group; analysis of health-care financing and its sources, as well of the recent financial desequilibrium, its causes and measures to restore the equilibrium; description of health care benefits and their differences among groups and regions, analysis of the country's advances in health-care facilities and standards, and measurement of the impact of the health care system in income distribution; and description of the rising cost of health care and the current crisis, analysis of the causes of both phenomena, and review of the measures that have been and should be implemented to solve these problems.

    It is reported the prevalence, magnitude and determinant factors of nutritional anaemia in a sample of nursing women (NW), collected during the National Nutrition Survey, of Costa Rica done in 1996. Nutritional anaemia was determinate through measurements of haemoglobin, and plasma ferritin, folates, cianocobalamin and retinol. Methodologies used were cianometahaemoglobin, solid phase immunoradiometric assay, solid phase radioimmunoassay and high-pressure liquid chromatography. WHO cut-off points were used. Anaemia was present in 22.1% of the women. Iron and folate deficiency were found in 48.7 and 84.2% NW, respectively. The magnitude of anaemia was mild and iron and folate deficiencies were severe. Vitamin B12 and A deficiencies were 5.3 and 4.9%, respectively and did not represent a public health problem in this group. Prevalent deficiency was mixed (iron and folates, 46.6%) followed by exclusive folates deficiency (32%). Anaemia was caused by a combined deficiency of iron and folates (61.1%) and most iron deficiencies were accompanied by folates (92%). The logistic regression analysis demonstrated that low socio-economic level of NW and their families was the principal factor determining the appearance of nutritional anaemia, and educative interventions to the mother are possibly recommended. In conclusion anaemia in NW is a moderate health problem of nutritional type, that is more important when severe folates and iron deficiencies are present in Costa Rica. These problems have remained constant throughout the last three decades; although recently, possibly an improvement has occurred because the prevalence of neural tube defects in the infant population has reduced, maybe due to food iron and folates fortification public health policies implementation.

    Full Text Available La Fiebre Manchada de la Montañas Rocosas es una zoonosis transmitida por garrapatas y causada por una bacteria intracelular obligatoria, la Rickettsia rickettsii. Es una enfermedad sistémica, de moderada a severa, producida por la infección del endotelio vascular de pequeños vasos de la mayoría de órganos y tejidos. Es la más letal de las infecciones transmitidas por garrapatas y desde su descubrimiento, hace cerca de 100 años, todavía se presenta, aunque esporádicamente, de forma persistente, y a pesar de que se cuenta con antibióticos efectivos, la mortalidad sigue siendo de mas del 10% y los pacientes requieren terapia intensiva durante la infección si esta no es diagnosticada y tratada a tiempo. En tiempo recientemente se han descrito otras especies de garrapatas que pueden transmitir rickettsias a humanos así como nuevas especies de rickettsias que pueden producir cuadros de fiebres manchadas y aunque se ha dilucidado parte de sus mecanismos patogénicos, persisten muchas dudas respecto a su virulencia. Desde 1975 se han reportado brotes de esta enfermedad en Costa Rica y el agente etiológico causal, la Rickettsia rickettsii, fue aislada e identificada en la mayoría de los casos en el Laboratorio de Virología de la Facultad de Microbiología de la Universidad de Costa Rica.

    This study describes the dynamics of adolescent childbearing of Nicaraguan-born and Costa Rican-born adolescents in Costa Rica and examines the association between socio-demographic factors and adolescent childbearing in the country. We studied Nicaraguan-born and Costa Rican adolescents using the data of the 2000 Census. Multivariate logistic regression was used to analyze the association between country of origin and adolescent childbearing, while controlling for socio-demographic factors (age, education, union, urbanization and poverty). 26% of Nicaraguan-born migrants and 9.5% of Costa Ricans had given birth during adolescence. The migrants' increased odds of pregnancy decreased from 3.34 (CI 3.21, 3.48) to 1.88 (CI 1.79, 1.97) when controlling for socio-demographic factors. Age, low educational attainment, urban residence, poverty and union were all significant predictors of adolescent pregnancy. Nicaraguan-born status is associated with adolescent childbearing in Costa Rica. Further research is needed to understand what factors, other than socio-demographic indicators, contribute to the differing prevalence of adolescent childbearing in Costa Rica.

    Recent studies in Central America indicate that mortality attributable to chronic kidney disease (CKD) is rising rapidly. We sought to determine the prevalence and regional variation of CKD and the relationship of biologic and socio-economic factors to CKD risk in the older-adult population of Costa Rica. We used data from the Costa Rican Longevity and Health Aging Study (CRELES). The cohort was comprised of 2657 adults born before 1946 in Costa Rica, chosen through a sampling algorithm to represent the national population of Costa Ricans >60 years of age. Participants answered questionnaire data and completed laboratory testing. The primary outcome of this study was CKD, defined as an estimated glomerular filtration rate (eGFR) <60 ml/min/1.73 m(2) . The estimated prevalence of CKD for older Costa Ricans was 20% (95% CI 18.5-21.9%). In multivariable logistic regression, older age (adjusted odds ratio [aOR] 1.08 per year, 95% CI 1.07-1.10, P < 0.001) was independently associated with CKD. For every 200 m above sea level of residence, subjects' odds of CKD increased 26% (aOR 1.26 95% CI 1.15-1.38, P < 0.001). There was large regional variation in adjusted CKD prevalence, highest in Limon (40%, 95% CI 30-50%) and Guanacaste (36%, 95% CI 26-46%) provinces. Regional and altitude effects remained robust after adjustment for socio-economic status. We observed large regional and altitude-related variations in CKD prevalence in Costa Rica, not explained by the distribution of traditional CKD risk factors. More studies are needed to explore the potential association of geographic and environmental exposures with the risk of CKD. © 2015 John Wiley & Sons Ltd.

    Full Text Available The genus Fluviphylax Whitley, 1965 is comprized of five valid species (F. pygmaeus Myers et Carvalho, 1955, F. zonatus, F. simplex, F. obscurus Costa, 1996, and F. palikur Costa et Le Bail, 1999, which are endemic to the Amazon region. These fishes are the smallest known South American vertebrates and among the smallest know vertebrates on Earth. All species but the type F. pygmaeus have been described in late 1990’s, and much remains unknown about the biology, taxonomy and systematics of this group of fishes. The aims of the present study were to establish the diploid and haploid number of F. zonatus and F. simplex, and to find species-specific markers for the discrimination of taxa. The diploid number for both species was 48 chromosomes, with no sex chromosome heteromorphism. Fluviphylax zonatus exhibited the karyotypic formula 4m+8sm+22st+14a and FN=82, and F. simplex exhibited 4m+16sm+18st+10a and FN=86. The determination of the total mean length of the chromosomes and their grouping into five size classes demonstrated different chromosome composition of the two species. This difference was further supported by the distribution of constitutive heterochromatin. The meiotic analysis revealed 24 bivalents in both species, but F. zonatus exhibited chromosomes with late pairing of the telomeric portions in the pachytene. These data reveal that cytogenetic characterization is useful and important for the discrimination of these species. Our study further indicates that this method could be employed in the analysis of other species of small fishes that are difficult to distinguish using traditional morphological traits or are morphologically cryptic.

    General view of NA44 experiment. NA44 is one of the seven experiments (NA44, NA45, NA49, NA50, NA52, WA97/NA57 and WA98) involved in CERN'S Heavy Ion programme which provided evidence for the existence of a new state of matter in which quarks, instead of being bound up into more complex particles such as protons and neutrons, are liberated and roam freely. Theory predicts that this state must have existed at about 10 microseconds after the Big Bang, before the formation of matter as we know it today.

    Full Text Available Este artigo busca contribuir para um conhecimento mais aprofundado da política econômica da ditadura militar, concentrando-se num período tratado na literatura de uma forma indevidamente generalista - qual seja, o governo Costa e Silva, caracterizado pelo início da retomada do crescimento e por inflexões na condução da política econômica. Procura-se mostrar que a política econômica do regime experimenta uma importante reorientação em relação ao governo Castello Branco, procedendo-se a uma tentativa de síntese da perspectiva heterodoxa que então tornou-se dominante. Entretanto, é equivocado projetar linearmente sobre todo o período o ideário heterodoxo manifestado durante 1967-1968: com efeito, após o AI-5, durante o ano de 1969 a política econômica obedece a um movimento muito distinto, o qual é objeto de uma detalhada reconstituição.This article aims to contribute to a deeper understanding of the Brazil's economic policy during the military dictatorship, focusing a period which is treated by the literature in a predominantly general way - the Administration Costa e Silva, characterized by the resumption of the accelerated economic growth but also by important swings in the conduct of economic policy. The article seeks to show that the regime's economic policy exhibits a major change, abandoning the principles associated with the Castello Branco Administration; a synthesis of the so-called heterodoxy approach which then emerged is delineated. The main argument, however, is that it is a dubious procedure to see all the subsequent conduct of economic policy as a reflection of that new approach - which effectively prevailed during 1967-1968, but after AI-5 reinforced the authoritarian nature of the regime. A carefully detailed description of the conduct of economic policy during 1969 sheds light on this issue.

    Full Text Available Cancer is a worldwide problem because of its high rates of incidence and associated mortality. By 2000, more than 6.2 million people died from this illness worldwide. Among all types of cancer, breast cancer is one of the most studied. Each year, one million new cases are diagnosed around the world. We can classify breast cancer into two main kinds: sporadic cases and those which are a product of inherited genetic alterations. Approximately 5-10% of breast cancer cases are the result of inherited mutations, or alterations in breast cancer susceptibility genes, BRCA1 and BRCA2. Like other countries, Costa Rica possesses high rates of incidence and mortality for breast cancer. According to the "Registro Nacional de Tumores" (National Office of Tumor Records, in 2000 breast cancer had the highest rate of incidence and in 2002 it had the highest rate of mortality in comparison to other types of cancer. For this reason and the generalized lack of knowledge in the field we conducted an epidemiological research on breast cancer patients from Hospital San Juan de Dios, San José, Costa Rica, to find families with a history of breast cancer, and to determine the occurrence of familial cases within the population studied. So far, we have found 23 families, within which we discovered very informative cases that have rendered the identification of a pattern of inheritance. These findings allow us to announce that in Costa Rica there are several cases of inherited breast cancer and that we need more research is needed to improve the prevention, control, and treatment of this disease.

  8. The declining effect of sibling size on children's education in Costa Rica

    Full Text Available Background: Costa Rica experienced a dramatic fertility decline in the 1960s and 1970s. The same period saw substantial improvement in children's educational attainment in Costa Rica. This correlation is consistent with household-level quantity-quality tradeoffs, but prior research on quantity-quality tradeoff magnitudes is mixed, and little research has estimated quantity-quality tradeoff behaviors in Latin America. Objective: This study explores one dimension of the potential demographic dividend from the fertility decline: the extent to which it was accompanied by quantity-quality tradeoffs leading to higher educational attainment. Specifically, we provide the first estimate of quantity-quality tradeoffs in Costa Rica, analyzing the increase in secondary school attendance among Costa Rican children as the number of siblings decreases. Furthermore, we advance the literature by exploring how that tradeoff has changed over time. Methods: We use 1984 and 2000 Costa Rican census data as well as survey data from the Costa Rican Longevity and Healthy Aging Study (CRELES. To address endogenous family size, the analysis uses an instrumental variable strategy based on the gender of the first two children to identify the causal relationship between number of siblings and children's education. Results: We find that, among our earlier cohorts, having fewer siblings is associated with a significantly higher probability of having attended at least one year of secondary school, particularly among girls. The effect is stronger after we account for the endogeneity of number of children born by the mother. For birth cohorts after 1980 this relationship largely disappears. Conclusions: This study provides strong evidence for a declining quantity-quality (Q-Q tradeoff in Costa Rica. This result suggests one potential explanation for the heterogeneous findings in prior studies elsewhere, but more work will be required to understand why such tradeoffs might vary

    Full Text Available Resumen La operación de las actividades económicas y su competitividad, analizadas desde una perspectiva de cadenas globales de mercancías, dependen del funcionamiento de los mercados de crédito, tanto nacionales como internacionales. La operación normal de los negocios requiere crédito para fortalecer sus recursos propios y hacer las compras de materia prima, insumos, pago de salarios e inversión. En todos los casos, el crédito puede ser utilizado para mejorar el diseño de productos, impulsar el acceso a nuevos mercados y aumentar la competitividad. A los productores de la región de Los Santos en Costa Rica se les reconoce por innovadores, y al café de la zona por ser un café de altura y de gran calidad. El artículo explora las necesidades de financiamiento de productores, beneficiadores y exportadores de café de Los Santos, sus fuentes de financiamiento y el uso dado a los recursos obtenidos. Entre las necesidades orientadas al mejoramiento de la competitividad se encontraron la renovación de cafetales entre los productores, el mantenimiento de proyectos y tecnología entre los beneficios y la generación de microbeneficios y búsqueda de nichos de mercado entre los exportadores. Abstract From a global commodity chains perspective, economic activities and their competitiveness depend upon the functioning of credit markets, both international and domestic. Current businesses operations require credit to enhance their own resources in order to buy raw material and inputs, pay wages and make investment. Credit may also be used to improve product design, enter new markets and boost competitiveness as a result. High altitude grown coffee from Los Santos, Costa Rica is widely known for its quality, and their growers as innovative. This paper addresses credit needs of coffee growers, processors and exporters in Los Santos, the credit sources they have access to, and the kind of uses the credit is given.

Swimming ability was evaluated by observing the use of limbs and tail in the water, inclination to the surface, and diving and floating behavior. Rice rats could float, swim and dive, suggesting that they can exploit surface and underwater resources. Cotton rats swam at the water’s surface, but were less skilled swimmers than rice rats. Spiny pocket mice tired quickly and had difficulty staying at the water’s surface. Results suggest that differential swimming ability is related to the distribution of the three sympatric species within the marsh and adjacent forest habitatsNosotros investigamos las habilidades de nado de tres ratones del bosque seco de Costa Rica (la rata arrocera de Coue, Oryzomys couesi, la rata algodonera híspida, Sigmodon hispidus, y el ratón espinoso, Liomys salvini asociados a un gran pantano, Laguna Palo Verde, usando pruebas de nado de 90 s en un contenedor de plástico. La habilidad de nado fue evaluada observando el uso de las extremidades y cola en el agua, inclinación hacia la superficie y comportamiento de flotar y buceo. Las ratas arroceras pudieron flotar, nadar y bucear, sugiriendo que ellas pueden explotar los recursos en la superficie y bajo el agua. Las ratas algodoneras nadaron en la superficie del agua, pero fueron menos hábiles nadadoras que las rata arroceras. Los ratones espinosos se cansaron rápidamente y tuvieron dificultad para mantenerse en la superficie del agua. Los resultados sugieren que la habilidad de nado diferencial está relacionada con la distribución de las tres especies simpátricas dentro del pantano y los hábitats del bosque adyacentes

    Costa Rica's La Selva-Braulio Carrillo complex encompasses a 60-km protected corridor of Caribbean rain and cloud forest extending from 30 m at the La Selva Biological Station to 2,906 m at the top of Volcán Barva. The 52,000-ha complex covers four life zones and two transitional zones, including tropical wet forest, tropical wet forest cool-transition, tropical premontane wet-transition rain forest, tropical premontane rain forest, lower montane rain forest, and montane rain forest. Located in the northeastern part of the country, the area is representative of Central American Caribbean slope forests that extend from Mexico to Panama. The extensive elevational gradient of the complex provides protected habitat for a variety of altitudinal migrants. With support from the National Geographic Society and Rice Foundation, the Organization for Tropical Studies organized a biological survey of the complex in early 1986. The mammal team worked at six sites along the elevational transect established by the expedition: 300 m, 700 m, 1,000 m, 1,500 m, 2,050 m, and 2,600 m. We supplemented our collecting records with unpublished records made available by colleagues, records in the published literature, and specimens in museum collections. In addition, observations recorded by a variety of observers at the La Selva Biological Station are summarized. The mammal fauna of the complex comprises 142 species including 79 bats, 23 rodents, 15 carnivores, 7 marsupials, 6 edentates, 4 artiodactyls, 3 primates, 2 rabbits, 2 shrews, and 1 perissodactyl. At least 10 additional species are likely to occur there. The only species of mammal likely to have been extirpated from the area is the giant anteater. Recognizing the importance of the area to wildlife and to mankind in general, the government of Costa Rica added 13,500 ha to the complex on 13 April 1986. This area, previously known as the “Zona Protectora,” provided the mid-elevational link between the lowlands of the La Selva

    The studies on marine copepods of Costa Rica started in the 1990's and focused on the largest coastal-estuarine systems in the country, particularly along the Pacific coast. Diversity is widely variable among these systems: 40 species have been recorded in the Culebra Bay influenced by upwelling, northern Pacific coast, only 12 in the Gulf of Nicoya estuarine system, and 38 in Golfo Dulce, an anoxic basin in the southern Pacific coast of the country. Freshwater environments of Costa Rica are known to harbor a moderate diversity of continental copepods (25 species), which includes 6 calanoids, 17 cyclopoids and only two harpacticoids.

The freshwater copepod fauna of Costa Rica is clearly the best known in Central America. Overall, six of the 10 orders of Copepoda are reported from Costa Rica. A previous summary by 2001 of the free-living copepod diversity in the country included 80 marine species (67 pelagic, 13 benthic). By 2009, the number of marine species increased to 209: 164 from the Pacific (49% of the copepod fauna from the Eastern Tropical Pacific) and 45 from the Caribbean coast (8% of species known from the Caribbean Basin).

    Although most Central American magmas have a typical arc geochemical signature, magmas in southern Central America have isotopic and trace element compositions with an OIB affinity, similar to the Galapagos hotspot lavas. Our new data for Costa Rica suggest that this signature, unusual for a convergent margin, has a relatively recent origin (Late Miocene-Pliocene ca. 6 Ma). We also show that there was a transition from typical arc magmas (analogous to the modern Nicaraguan volcanic front) to OIB-like magmas. The geographic distribution of the Galapagos signature in recent lavas from southern Central America is present landward from the subduction of the Galapagos hotspot tracks (the Seamount Province and the Cocos/Coiba Ridges) at the Middle American Trench. The higher Pb isotopic ratios, relatively low Nd isotopic ratios and enriched geochemical signature of central Costa Rican magmas can be explained by arc-hotspot interaction. The isotopic ratios of central Costa Rican lavas require the subducting Seamount Province (Northern Galapagos Domain) component, whereas the isotopic ratios of the adakites and alkaline basalts from southern Costa Rica and Panama are in the geochemical range of the subducting Cocos/Coiba Ridges (Central Galapagos Domain). Geological, geochemical, and isotopic evidence collectively indicate that the relatively recent Galapagos-OIB signature in southern Central America represents a geochemical signal from subducting Galapagos hotspot tracks, which started to collide with the margin ~8 Ma ago. The Galapagos hotspot contribution decreases systematically along the volcanic front from central Costa Rica to NW Nicaragua.

    This report assesses the potential for substitution of electricity for petroleum in the industrial/agro-industrial sector of Costa Rica. The study includes a preliminary estimate of the process energy needs in this sector, a survey of the principal petroleum consuming industries in Costa Rica, an assessment of the electrical technologies appropriate for substitution, and an analysis of the cost trade offs of alternative fuels and technologies. The report summarizes the total substitution potential both by technical feasibility and by cost effectiveness under varying fuel price scenarios and identifies major institutional constraints to the introduction of electric based technologies. Recommendations to the Government of Costa Rica are presented. The key to the success of a Costa Rican program for substitution of electricity for petroleum in industry rests in energy pricing policy. The report shows that if Costa Rica Bunker C prices are increased to compare equitably with Caribbean Bunker C prices, and increase at 3 percent per annum relative to a special industrial electricity rate structure, the entire substitution program, including both industrial and national electric investment, would be cost effective. The definition of these pricing structures and their potential impacts need to be assessed in depth.

    Marine sediment samples from four coastal ecosystems in Costa Rica were taken between the years 2000-2002 and their iron, lead, copper and zinc concentrations were determined by the atomic absorption technique with flame or graphite furnace. In the Pacific coast, Culebra Bay (Papagayo Gulf), Gulf of Nicoya, and Golfito Bay (Dulce Gulf), were selected as representative sites, and Moín Bay, at the Caribbean coast. Mean metal concentrations for all ecosystems followed the same pattern: Fe > Zn > Cu > Pb. No temporal pattern was found for any metal. Iron and copper mean concentrations were higher in Golfito Bay (5.8% and 87 microg/g, respectively) and lower in Moín Bay (3.4% and 52 microg/g, respectively). Zinc mean concentration was also higher in Golfito Bay (96 microg/g), but lower in Culebra Bay (66 microg/g). Lead mean concentration was higher in Moín Bay (6.4 microg/g) and lower in Culebra Bay (3.0 microg/g). Lead highest concentrations occurred in the Caribbean and in Golfito Bay, and for the rest of the elements the maximum values were found in Golfito Bay. On the basis of data obtained in this work, Culebra Bay was considered a relatively unpolluted location; Golfito Bay was more contaminated, and Moín Bay and the Gulf of Nicoya showed an intermediate condition.

    In agreement with the Broecker and Penn two-boxes model, I generated a biogeochemical balance model for the Gulf of Nicoya (Guanacaste, Costa Rica) using two nutrient reservoirs: surface water and deep water. The mixing zone was located at a depth of 20 m. There is a balance between surface waters descending to the bottom and upwelling waters that carry nutrients and other chemical elements to the surface. The main source of nitrogen (nitrate), was the outlet of the Tempisque and Tárcoles rivers. The Gulf of Nicoya is a net source of Dissolved Inorganic Nitrogen (DIN) with an availability rate of 87 x 10(3) mol day(-1) in the dry season and 3044 x 10(3) mol day(-1)in the rainy season. Dissolved Inorganic Phosphate (DIP) was estimated in 27 mol day(-1) in the dry season and 207 mol day(-1) in the rainy season. The dynamics of these biolimited nutrients, in relation to runoff seasonal variations, fits the biological processes reported for the gulf, for example, for variations in primary productivity levels, and maturity and reproduction seasons for species with short and long life cycles.

    Three daily samplings of the phytoplankton community were made at two consecutive days in March, April, May, September, October, November and December 1997, at Punta Morales, Golfo de Nicoya, Costa Rica. Samples were collected during each tide at depths of 50% and 10% of light penetration using a Niskin bottle. A total of 43 taxa were identified. Centric diatoms, pennates and flagellates represented 90% of total phytoplankton abundance. In the phytoplankton fraction (cells > 30 microm), diatoms were the most abundant group, and Skeletonema costatum (32%) dominated. In nannophytoplankton (cells < 30 microm), Chaetoceros (23.7%) was the most abundant taxon, followed by flagellates (23%) and Cylindrotheca closterium (13.1%). These results agree with previous surveys and suggest that a typical net phytoplankton community persist through time in the Punta Morales zone. The number of nannophytoplankton fraction cells varied seasonally and suggests quantitative changes in species abundance, with possible modifications of cellular size or chain length in filamentous species. The codominance between S. costatum and Chaetoceros spp. during the rainy season suggested the ocurrence of an early ecological sucession, and nutrients could be the factor generating such population changes.

    Cervical and uterine cancer continues to be an important issue for women around the world, although neoplasia has the greatest demonstrated potential for prevention. Costa Rica has achieved important advances in the reduction of the incidence and mortality of these cancers since the last century. This is the result of a series of policies, programmes, and plans, not only at the level of the health care system, but also in other areas. Increased access for women to care in health centres, fundamentally at the primary level, has been vital, as has ensuring the quality of cytology readings and access to diagnosis and treatment for precursor lesions for in situ and invasive cancers. Despite all of these achievements, there are still challenges to be overcome, which are widespread in many countries in Latin America and the Caribbean. It is important to learn from the experiences of other countries in order to improve women's health not only as a health objective, but also as an ethical imperative to promote the exercise of women's rights to life and health.

    Turrialba volcano is an active composite stratovolcano that is located approximately 40 km east of San Jose, Costa Rica. Seismic activity and degassing have increased since 2005, and gas compositions reflect further increased activity since 2007 peaking in January 2010 with a phreatic eruption. Gas fumes dispersed by trade winds toward the west, northwest, and southwest flanks of Turrialba volcano have caused significant vegetation kill zones, in areas important to local agriculture, including dairy pastures and potato fields, wildlife and human populations. In addition to extensive vegetative degradation is the potential for soil and water contamination and soil erosion. Summit fumarole temperatures have been measured over 200 degrees C and gas emissions are dominated by SO2; gas and vapor plumes reach up to 2 km (fumaroles and gases are measured regularly by OVSICORI-UNA). A recent network of passive air sampling, monitoring of water temperatures of hydrothermal systems, and soil pH measurements coupled with measurement of the physiological status of surrounding plants using gas exchange and fluorescence measurements to: (1) identify physiological correlations between leaf-level gas exchange and chlorophyll fluorescence measurements of plants under long term stress induced by the volcanic gas emissions, and (2) use measurements in tandem with remotely sensed reflectance-derived fluorescence ratio indices to track natural photo inhibition caused by volcanic gas emissions, for use in monitoring plant stress and photosynthetic function. Results may prove helpful in developing potential land management strategies to maintain the biological health of the area.

    To examine whether total physical activity or activity patterns are associated with metabolic syndrome and its components. Participants include 1994 controls from a case-control study of non-fatal myocardial infarction in Costa Rica (1994-2004). Physical activity was assessed via self-administered questionnaire and patterns were identified using principal components analysis. Metabolic syndrome was assessed via blood samples and anthropometry measurements from in-home study visits. Prevalence ratios (PRs) and 95% confidence intervals (CIs) were calculated using log binomial regression. Adjusted least squares means of metabolic syndrome components were calculated by quintile of total activity and pattern scores. Four activity patterns were identified: rest/sleep, agricultural, light indoor activity, and manual labor. Total activity was not associated with metabolic syndrome. Metabolic syndrome prevalence was 20% lower in participants with the highest scores on the agricultural job pattern compared to those with the lowest (PR: 0.80, 95% CI: 0.68-0.94). Higher total activity was associated with lower triglycerides and lower HDL cholesterol. Higher scores on each pattern were inversely associated with metabolic syndrome components, particularly waist circumference and fasting blood glucose. Patterns or types of physical activity may be more strongly associated with metabolic syndrome and its components than total activity levels. Copyright © 2014 Elsevier Inc. All rights reserved.

    2009-04-01

    Knowledge about seasonal runoff patterns is indispensable for water management, for example, for sustainable hydropower regulation schemes. Seasonal runoff patterns have been identified for 56 27-years long monthly runoff series for Costa Rica. The high intrinsic dimensionality of many monthly runoff series analysed reveals high instability of their seasonal patterns suggesting differences in patterns demonstrated during individual years and the average seasonal pattern. In this study the focus was put on patterns observed during individual years and their relation to teleconnections. To match the scale of variations of these latter the analyses were performed on five grouped samples of monthly runoff that represent different geographical regions. In some of the groups there was a significant correlation between the presence of the seasonal patterns studied and individual teleconnections but the values of the correlation coefficient were rather low. Analyses of the contingency tables showing the phase (higher/lower than the mean) of teleconnection or their combinations and the frequency of seasonal patterns in a group with different lags showed that for certain combinations of phases these frequencies increase considerably. This finding opens for a possibility of probabilistic forecasts of seasonal patterns using information on teleconnections.

We aim to establish our reference values, to compare them with the original and the Mexican population, and to associate some variables with the type of peritoneal transport. Methods. Thirty peritoneal equilibration tests (PET were performed. The ratio for D/P creatinine and the D/D0 ratio for glucose were calculated and compared to reference values. We conducted a retrospective analysis to correlate peritoneal transporters with some predictive variables. Results. D/P creatinine ratio at 2 hours, D/D0 glucose ratio at 4 hours, and net ultrafiltrate volume (nUFV were significantly different from those reported by Twardowski et al. The results documented in the Mexican population only coincide with our results for the D/P creatinine ratio at 4 hours. Any of the studied variables were associated with a specific type of peritoneal transport. Conclusions. Peritoneal permeability among Costa Rican CAPD patients is different from the original population described by Twardowski et al. and from other Latin-American population. This supports the theory that ethnical differences could be responsible for such variations and they validate our statement that each region should possess value references of their own.

    Beginning in early 2006, an ocular disease of unknown etiology was routinely observed in American crocodiles (Crocodylus acutus) inhabiting the highly polluted Tarcoles River in west-central Costa Rica. We examined the nature and incidence of ocular disease in Tarcoles crocodiles and assessed the possible association between the disease and accumulation of chemical pollutants in diseased individuals. During 12-15 September and 12-13 December 2007, crocodiles were captured and examined for ocular disease and sampled to determine environmental contaminant accumulation. Three of 11 (27.3%) crocodiles captured (all males) exhibited unilateral ocular disease, primarily characterized by corneal opacity and scarring, anterior synechia, and phthisis bulbi. Multiple pollutants were detected in crocodile caudal scutes (organochlorine pesticides [OCPs] and metals), crocodile blood (OCPs), and sediments (OCPs and metals) from the Tarcoles, but no associations were found between contaminant accumulation and the incidence of eye disease. On the basis of the limited number of diseased animals examined and the potential exposure of crocodiles to pathogens and other pollutants not targeted in this study, we cannot rule out infection or chemical toxicosis as causes of the eye lesions. However, circumstantial evidence suggests that the observed ocular disease is likely the result of injury-induced trauma (and possibly secondary infection) inflicted during aggressive encounters (e.g., territorial combat) among large adult crocodiles living at relatively high densities.

    Full Text Available Dogs with the presumptive diagnosis of Chagas disease are commonly sent to our School of Veterinary Medicine by independent veterinarians. This prompted us to evaluate the prevalence of canine trypanosomiasis in some villages of the Central Valley of Costa Rica. A total of 54 dogs (21 males and 33 females from five rural villages, with ages between 3 months and 10 years old, were bled and submitted to three serological tests: indirect immunofluorescence, indirect hemagglutination and ELISA. Among all animals, 15 (27.7% revealed antibodies (6 pure bred and 9 mongrels and in 3 of them the parasite was also demonstrated by xenodiagnosis.

Examination of 50 inhabitants living in the houses where dogs and Triatoma dimidiata were found, yielded negative serological reactions. This was assumed to support the hypothesis that dogs are commonly infected by the oral route, a more effective means of infection compared with the vector transmission mechanism that occurs in humans.

  5. Conversion or conservation? Understanding wetland change in northwest Costa Rica.

    Wetlands are more threatened than any other ecosystem type, with losses exceeding 50% of their original extent worldwide. Despite the small portion of the Earth's surface that they comprise, wetlands contribute significantly to global ecosystem services. In this study, we tested the hypothesis that the location and rate of change in wetland amount in the Tempisque Basin of northwest Costa Rica is predictable from landscape setting. Our results demonstrate that a strong potential exists for developing predictive models of wetland conversion based on an understanding of wetland location and surrounding trends of land use. We found that topography was the single most important predictor of wetland conversion in this area, entraining other conversion processes, and that spatial patterns of wetland loss could consistently be predicted from landscape-level variables. Areas with highest probabilities of conversion were found in the most accessible, non-protected regions of the landscape. While Palo Verde National Park made a substantial contribution to wetland conservation, our results highlight the dependence of lower-lying protected areas on upland processes, adding a little-addressed dimension of complexity to the dialogue about protected area management. Conservation strategies aimed at reducing wetland loss in tropical habitats will benefit from careful analysis of the dominant land use system(s) at a relatively broad scale, and the subsequent development of management and policy responses that take into account dynamic opportunities and constraints in the landscape.

  6. A clandestine burial in Costa Rica: prospection and excavation.

    Congram, Derek R

    2008-07-01

    This case report describes the search for a clandestine grave in Costa Rica for which the police sought the assistance of an archaeologist. An anonymous informant suggested that the victim had been kidnapped and murdered, placed in a shallow grave in the woods, then covered with lime and cement. A search of the area to detect conventional signs of burial (e.g., slumping, different plant growth) resulted in excavation of unrelated features of past disturbance. Different aspects of the grave including the deposition of cement powder over the body prevented its initial discovery. Improvisation of conventional archaeological excavation methods and use of police familiar with archaeological excavation resulted in the location of the grave and exhumation of the victim without loss of important contextual evidence that supported testimony on the cause of death. The taphonomic effects of high-lying ground water and lime in the tropical burial environment are briefly discussed. Recommendations such as the construction of a temporary sump to lower the ground water level in the grave during excavation are made to assist in similar investigations in the future.

    Objective To examine whether total physical activity or activity patterns are associated with metabolic syndrome and its components. Methods Participants include 1,994 controls from a case-control study of non-fatal myocardial infarction in Costa Rica (1994–2004). Physical activity was assessed via self-administered questionnaire and patterns were identified using principal components analysis. Metabolic syndrome was assessed via blood samples and anthropometry measurements from in-home study visits. Prevalence ratios (PR) and 95% confidence intervals (CI) were calculated using log binomial regression. Adjusted least squares means of metabolic syndrome components were calculated by quintile of total activity and pattern scores. Results Four activity patterns were identified: rest/sleep, agricultural, light indoor activity, and manual labor. Total activity was not associated with metabolic syndrome. Metabolic syndrome prevalence was 20% lower in participants with the highest scores on the agricultural job pattern compared to those with the lowest (PR: 0.80, 95% CI: 0.68–0.94). Higher total activity was associated with lower triglycerides and lower HDL cholesterol. Higher scores on each pattern were inversely associated with metabolic syndrome components, particularly waist circumference and fasting blood glucose. Conclusions Patterns or types of physical activity may be more strongly associated with metabolic syndrome and its components than total activity levels. PMID:25445330

    Full Text Available Introduction. Home visit is the main strategy of primary care by bringing health services to the homes and workplaces of people, which allows knowing the needs of the population firsthand. Thus, home visit by the ATAP represents the first contact of the individual, family and community with the health system, with significant benefits both individually and collectively. This research responds to the need to identify the elements that the home visiting program needs to improve modify or replace in order to maximize the provision of this service.Method. It is a qualitative, observational analytic study. Data were collected through documentary research, key informant interviews and focus group. The analysis was performed from the grounded theory.Results. The main results showed the existence of elements at the level of the health system, home visiting program and the figure of the ATAP that should be reviewed, modified or replaced to the home visit, thus it has bigger and better results for the population and the health system.Conclusion. The Home Visiting Program is strength of the Costa Rican health system to address health inequities. However, it is imperative to make decisions and implementation of actions that promote the improvement and increased results of the home visit at a family and community level.

Es una enfermedad sistémica, de moderada a severa, producida por la infección del endotelio vascular de pequeños vasos de la mayoría de órganos y tejidos. Es la más letal de las infecciones transmitidas por garrapatas y desde su descubrimiento, hace cerca de 100 años, todavía se presenta, aunque esporádicamente, de forma persistente, y a pesar de que se cuenta con antibióticos efectivos, la mortalidad sigue siendo de mas del 10% y los pacientes requieren terapia intensiva durante la infección si esta no es diagnosticada y tratada a tiempo. En tiempo recientemente se han descrito otras especies de garrapatas que pueden transmitir rickettsias a humanos así como nuevas especies de rickettsias que pueden producir cuadros de fiebres manchadas y aunque se ha dilucidado parte de sus mecanismos patogénicos, persisten muchas dudas respecto a su virulencia. Desde 1975 se han reportado brotes de esta enfermedad en Costa Rica y el agente etiológico causal, la Rickettsia rickettsii, fue aislada e identificada en la mayoría de los casos en el Laboratorio de Virología de la Facultad de Microbiología de la Universidad de Costa Rica.Rocky Mountain Spotted fever is a tick vector disease caused by an obligated intracellular bacteria, Rickettsia rickettsii.

  6. Plastic paradise: transforming bodies and selves in Costa Rica's cosmetic surgery tourism industry.

    Science.gov (United States)

    Ackerman, Sara L

    2010-10-01

    Long popular as a nature tourism destination, Costa Rica has recently emerged as a haven for middle class North Americans seeking inexpensive, state-of-the-art cosmetic surgery. This paper examines "cosmetic surgery tourism" in Costa Rica as a form of medicalized leisure, situated in elite private spaces and yet inextricably linked to a beleaguered national medical program. Through historical context and ethnographic analysis of activities at medical hotels and clinics, I describe how the recovery industry operates on the embodied subjectivities of visiting patients and their local caretakers. Recovery sociality and healing landscapes facilitate patients' transition through a period of post-surgical liminality and provide nostalgic transport to an imagined medical arcadia, while clinicians are attracted by a neoliberal promise of prosperity and autonomy. Ultimately, Costa Rica's transformation into a paradise of medical consumption and self-optimization is contingent on a mythology that obscures growing uncertainties and inequities in the nation's broader medical landscape.

  7. Space geodetic studies of crustal deformation in subduction zones: The Central Andes and Costa Rica

    Science.gov (United States)

    Norabuena, Edmundo O.

    Subduction zones are regions that account for most of the total energy released by large earthquakes around the world. Two of these regions, the Costa Rica Margin and the southern Peru Margin, historically prone to devastating earthquakes with severe social and economic impact, are the focus of my dissertation. I use GPS derived velocity fields estimated from time series of coordinates of campaign stations deployed between 1994 and 2001 over the Costa Rica and Peru subduction zones to infer fault geometry and slip distribution on the plate boundary, and study the corresponding seismogenic zones. Regions of locking are associated with asperities that may break at the end of the corresponding earthquake cycle; their area extent may signify amount of energy to be released. I also show that fore-arc motion in Costa Rica, as well as postseismic relaxation, are factors that contribute to or alter the observed velocity fields and must be taken into account.

    Full Text Available Price transmission analysis is an increasing research topic, especially for price taking countries such as Costa Rica. We describe the beef supply chain and provide a numerical implementation of Vector Error Correction Model (VECM of price transmission for the meat market in order to observe the relationship between import prices of meat and their effects on national retail prices. To restore equilibrium, retail prices correct 8% of the error term monthly. Since the meat imports market of Costa Rica is complex, the analysis of others business partners as Nicaragua should be included in order to compare the influence of these in local retail prices

  10. Using Social Networks to Educate Seismology to Non-Science Audiences in Costa Rica

    Science.gov (United States)

    Lücke, O. H.; Linkimer, L.

    2013-12-01

    Costa Rica has a very high rate of seismicity with 63 damaging earthquakes in its history as a nation and 12 felt earthquakes per month on average. In Costa Rica, earthquakes are part of everyday life; hence the inhabitants are highly aware of seismic activity and geological processes. However, formal educational programs and mainstream media have not yet addressed the appropriate way of educating the public on these topics, thus myths and misconceptions are common. With the increasing influence of social networks on information diffusion, they have become a new channel to address this issue in Costa Rica. The National Seismological Network of Costa Rica (RSN) is a joint effort between the University of Costa Rica and the Costa Rican Institute of Electricity. Since 1973, the RSN studies the seismicity and volcanic activity in the country. Starting on January 2011 the RSN has an active Facebook Page, in which felt earthquakes are reported and information on Seismology, geological processes, scientific talks, and RSN activities are routinely posted. Additionally, RSN gets almost instantaneous feedback from RSN followers including people from all rural and urban areas of Costa Rica. In this study, we analyze the demographics, geographic distribution, reach of specific Facebook posts per topic, and the episodic growth of RSN followers related to specific seismic events. We observe that 70 % of the RSN users are between ages from 18 to 34. We consistently observe that certain regions of the country have more Facebook activity, although those regions are not the most populated nor have a high connectivity index. We interpret this pattern as the result of a higher awareness to geological hazards in those specific areas. We notice that educational posts are as well 'liked' as most earthquake reports. For exceptional seismic events, we observe sudden increments in the number of RSN followers in the order of tens of thousands. For example, the May 2013 Sixaola earthquake (Mw

    2003-03-01

    We visited 51 lakes in Costa Rica as part of a broad-based survey to document their physical and chemical characteristics and how these relate to the mode of formation and geographical distribution of the lakes. The four oxbow lakes were low in elevation and tended to be turbid, high in conductivity and CO2, but low in dissolved O2; one of these, L. Gandoca, had a hypolimnion essentially composed of sea water. These were similar to the four wetland lakes, but the latter instead had low conductivities and pH, and turbidity was often due to tannins rather than suspended sediments. The thirteen artificial lakes formed a very heterogenous group, whose features varied depending on local factors. The thirteen lakes dammed by landslides, lava flows, or lahars occurred in areas with steep slopes, and were more likely to be stratified than most other types of lakes. The eight lakes that occupy volcanic craters tended to be deep, stratified, clear, and cool; two of these, L. Hule and L. Río Cuarto, appeared to be oligomictic (tending toward meromictic). The nine glacial lakes, all located above 3440 m elevation near Cerro Chirripó, were clear, cold, dilute, and are probably polymictic. Cluster analysis resulted in three significant groups of lakes. Cluster 1 included four calcium-rich lakes (average 48 mg l-1), Cluster 2 included fourteen lakes with more Si than Ca+2 and higher Cl- than the other clusters, and Cluster 3 included the remaining thirty-three lakes that were generally less concentrated. Each cluster included lakes of various origins located in different geographical regions; these data indicate that, apart from the high-altitude glacial lakes and lakes in the Miravalles area, similarity in lake chemistry is independent of lake distribution.

  15. Accumulation of atmospheric sulfur in some Costa Rican soils

    Science.gov (United States)

    Bern, Carleton R.; Townsend, Alan R.

    2013-01-01

    Sulfur is one of the macronutrient elements whose sources to terrestrial ecosystems should shift from dominance by rock-weathering to atmospheric deposition as soils and underlying substrate undergo progressive weathering and leaching. However, the nature and timing of this transition is not well known. We investigated sources of sulfur to tropical rain forests growing on basalt-derived soils in the Osa Peninsula region of Costa Rica. Sulfur sources were examined using stable isotope ratios (δ34S) and compared to chemical indices of soil development. The most weathered soils, and the forests they supported, are dominated by atmospheric sulfur, while a less weathered soil type contains both rock-derived and atmospheric sulfur. Patterns of increasing δ34S with increasing soil sulfur concentration across the landscape suggest atmospheric sulfur is accumulating, and little rock-derived sulfur has been retained. Soil sulfur, minus adsorbed sulfate, is correlated with carbon and nitrogen, implying that sulfur accumulation occurs as plants and microbes incorporate sulfur into organic matter. Only the lower depth increments of the more weathered soils contained significant adsorbed sulfate. The evidence suggests a pattern of soil development in which sulfur-bearing minerals in rock, such as sulfides, weather early relative to other minerals, and the released sulfate is leached away. Sulfur added via atmospheric deposition is retained as organic matter accumulates in the soil profile. Adsorbed sulfate accumulates later, driven by changes in soil chemistry and mineralogy. These aspects of sulfur behavior during pedogenesis in this environment may hasten the transition to dominance by atmospheric sources.

Ambas constituyen ejemplos de un nuevo tipo de mecanismo mutacional, llamado mutaciones inestables o dinámicas, expansión de tripletas, o amplificación del ADN. La DM1 se considera como la distrofia muscular más frecuente en los adultos y FRAXA es la principal causa de retardo mental hereditario. Este trabajo presenta resultados actualizados de un estudio prospectivo no aleatorio en pacientes clínicamente afectados, que se realiza con el objetivo de confirmar el diagnóstico con técnicas moleculares (Hibridación de Southern y reacción en cadena de la polimerasa, PCR, y llevar a cabo el tamizaje en cascada del resto de la familia para ofrecerles consejo genético adecuado. Se confirmó el diagnóstico clínico inicial en la mayoría de los casos de distrofia miotónica, pero en los casos con retardo mental, más de la mitad de los análisis resultaron negativos para la amplificación en el gen FMR1, específica de FRAXA. La razón principal para esto podría ser el cuadro clínico muy sutil que muestran los niños afectados antes de la pubertad. Los únicos métodos disponibles para prevenir estas discapacidades por el momento son, el tamizaje en cascada, el consejo genético y el aborto selectivo. De los cuales, el último no se puede llevar a cabo según las leyes vigentes en Costa Rica.

    Full Text Available The objective of this study was to check for the presence of resistance to clethodim in Poa annua populations observed in onion fields in the highlands of Cartago, Costa Rica. Two experiments were conducted; the first one was carried out, in 2007, in a greenhouse at the Fabio Baudrit Moreno Agricultural Experiment Station (EEAFBM, in Spanish, with seeds of plants from a farm where clethodim exercised good control (S population, and from another farm where clethodim showed a deficient control (R population. Both S and R populations were treated with different doses of clethodim (0.5X, 1.0X, 1.5X and 2.0X, being X the recommended commercial dose. In this experiment, control of the R population was 44% and 17% at doses of 1.5X and 2.0X, respectively, whereas control of the S population was 100% at either of those doses. The second experiment was carried out in 2009, seeds of two other P. annua populations were collected in a similar way: one population from an area where weed control was satisfactory (S, and the other population from an area of the farm where control was deficient (R. Seeds were sown, depending on the type, in plastic pots and sprayed with clethodim at doses of: 0. 1X, 2X, 4X, 8X, and 16X. There were significant differences in the reactions to clethodim of both P. annua populations The S population showed a higher percentage of control and less surviving plants than the R population. Several plants of the R population resisted up to 16X commercial doses of clethodim. Results of both experiments suggest the presence of P. annua populations resistant to clethodim.

    Full Text Available The aim of this study was to explore the extent of inter-regional genetic diversity present in the cattle of Costa Rica. 1498 DNA samples were collected (year 2013 from eight different regions within the country. Allelic frequencies and major population genetic parameters were determined for eighteen microsatellite markers. An analysis of molecular variance was also carried out and genetic distances were calculated between cattle from different regions. At the national level, a high allelic diversity was found, with an average of 14.6±1.01 observed alleles and 5.6+0.37 effective alleles per marker. Observed (Ho and expected (He heterozygosities were 0.76±0.01 and 0.81±01, respectively. Polymorphic Information Content (PIC and Coefficient of Inbreeding (FIS were 0.79±0.06 and 0.06±0.004, respectively. At the regional level, Ho ranged between 0.73±0.02 in the South Central region to 0.78±0.01 in the North Huetar region. The dendrogram showed three clearly distinct groups, Metropolitan Central and West Central regions in one group, Caribbean Huetar, South Central, Central Pacific and Chorotega regions in a second group; and North Huetar and Brunca regions in a third intermediate group. Estimates of genetic differentiation (RST were significant between regions from different groups and non-significant for regions within the same group. Genetic differences between regions are related to differential proliferation of breed groups based on their adaptability to the agro-ecological conditions and production systems prevailing in each region.

  1. Organochlorine chemicals and neurodegeneration among elderly subjects in Costa Rica

    Mora, A.M.; Barr, D.B.; Juncos, J.; Roman, N.; Wesseling, C.

    2016-01-01

    Background We previously screened 400 elderly Costa Ricans for neurodegenerative disease. Those reporting occupational pesticide exposure (18%) had an increased Parkinson’s disease (PD) risk (OR 2.57, 95% CI 0.91–7.26), and worse cognition (Mini-Mental States Exam (MMSE) 24.5 versus 25.9 points, p=0.01). We subsequently measured long-lasting organochlorine pesticides (β-HCH, DDE, DDT, and dieldrin) in a sub-sample (n=89). Dieldrin and β-HCH have been linked to PD, and DDE to Alzheimer’s disease. Methods We ran regression models for MMSE and tremor-at-rest to assess associations with pesticides in 89 subjects. Results The percent of β-HCH, DDE, DDT (parent compound for DDE), and dieldrin above their limit of detection (LOD) were 100%, 93%, 75%, and 57%, respectively. Tremor-at-rest was found in 21 subjects, and the mean MMSE was 25. Those who reported occupational pesticide exposure (n=36) had more detectable dieldrin samples (p=0.005), and higher mean levels of dieldrin (p=0.01), than those not reporting exposure. Other pesticides did not differ between those with and without self-reported occupational exposure. There was a positive but non-significant trend of higher risk for tremor-at-rest with higher dieldrin (p=0.10 for linear trend). Neither DDE nor DDT showed a relationship with MMSE. However, after excluding two outliers with the lowest MMSE scores, higher DDT levels showed some modest association with lower MMSE (p=0.09 for linear trend). Conclusions Our data are limited by small sample size. However, dieldrin was high in our population, has been previously linked to PD, and could be partly responsible for the excess PD risk seen in our population. PMID:25173053

    We are currently developing a series of drones and associated instrumentation to study Turrialba volcano in Costa Rica. This volcano has shown increasing activity during the last 20 years, and the volcano is currently in a state of heightened unrest as exemplified by recent explosive activity in May-August 2016. The eruptive activity has made the summit area inaccessible to normal gas monitoring activities, prompting development of new techniques to measure gas compositions. We have been using two drones, a DJI Spreading Wings S1000 octocopter and a Turbo Ace Matrix-i quadcopter, to airlift a series of instruments to measure volcanic gases in the plume of the volcano. These instruments comprise optical and electrochemical sensors to measure CO2, SO2, and H2S concentrations which are considered the most significant species to help forecast explosive eruptions and determine the relative proportions of magmatic and hydrothermal components in the volcanic gas. Additionally, cameras and sensors to measure air temperature, relative humidity, atmospheric pressure, and GPS location are included in the package to provide meteorological and geo-referenced information to complement the concentration data and provide a better picture of the volcano from a remote location. The integrated payloads weigh 1-2 kg, which can typically be flown by the drones in 10-20 minutes at altitudes of 2000-4000 meters. Preliminary tests at Turrialba in May 2016 have been very encouraging, and we are in the process of refining both the drones and the instrumentation packages for future flights. Our broader goals are to map gases in detail with the drones in order to make flux measurements of each species, and to apply this approach at other volcanoes.

    Serpentinization is a planetary process where ultramafic rocks react with fluids with important consequences on global biogeochemical cycles through formation of H2 and CH4. Exposed sections of upper-mantle rocks on continents, where meteoric water interacts with the ultramafic rocks, provide natural laboratories to study present-day serpentinization. Here, we present geochemical evidence of active serpentinization and methane vents in the Santa Elena Ophiolite (comprising 250 km2 of ultramafic rocks) in Costa Rica. The system is sustained by peridotites with a 50% degree of serpentinization. Two alkaline spring systems were discovered. The alkaline fluids pH ranged from 11.01 to 11.18. Mean hydroxide and carbonate concentrations were 52 mg/L and 38 mg/L. Mean dissolved calcium was 104 mg/L with a maximum of 167 mg/L. These springs are also characterized by low Mg (< 1 mg/L) and K (2.35 mg/L) and relatively high Na (21.4 mg/L) and chloride (27.1 mg/L) concentrations. Average spring temperature was 29.1°C. Active CH4 vents (24.3% volume) coupled with extensive carbonate deposits (magnesite and calcite with isotopic compositions within the range of similar ultramafic hosted systems) also provide strong evidence of active serpentinization. Groundwater and alkaline spring's hydrological connectivity was explored using stable isotope as natural tracers. Isotope composition of the alkaline fluids (d18O = -7.9‰, d2H = -51.4‰) was remarkably similar to the groundwater signature from 10 deep wells (30-70 m) (d18O = -7.6‰; dD = -48.0‰) sampled in local watersheds. These results support the hypothesis that during prolonged dry periods these alkaline springs are fed by deep subsurface storage. Mean electrical conductivity of the alkaline fluids (622 uS/cm) was considerably higher than of surface waters (470 uS/cm); this significant difference may be additional evidence of active serpentinization in the area. Overall, Santa Elena's varying weather conditions between

    2004-09-01

    Full Text Available In the last decade, the Costa Rican Central Valley population (CRCV, has received considerable scientific attention, attributed in part to a particularly interesting population structure. Two different and contradictory explanations have emerged: (1 An European-Amerindian-African admixed population, with some regional genetic heterocigosity and moderate degrees of consanguinity, similar to other Latin-American populations. (2 A genetic isolate, with a recent founder effect of European origin, genetically homogeneous, with a high inter-marriage rate, and with a high degree of consanguinity. Extensive civil and religious documentation, since the settlement of the current population, allows wide genealogy and isonymy studies useful in the analysis of both hypotheses. This paper reviews temporal and spatial aspects of endogamy and consanguinity in the CRCV as a key to understand population history. The average inbreeding coefficients ?(alpha between 1860 and 1969 show a general decrease within time. The consanguinity in the CRCV population is not homogeneous, and it is related to a variable geographic pattern. Results indicate that the endogamy frequencies are high but in general it was not correlated with alpha ?values. The general tendency shows a consanguinity decrease in time, and from rural to urban communities, repeating the tendencies observed in other countries with the same degree of development, and follows the general Western World tendency. Few human areas or communities in the world can be considered true genetic isolates. As shown, during last century, the CRCV population has had consanguinity values that definitively do not match those of true genetic isolates. A clear knowledge of the Costa Rican population genetic structure is needed to explain the origin of genetic diseases and its implications to the health system. Rev. Biol. Trop. 52(3: 629-644.

    1987-07-01

    The Geochemical Atlas of the San Jose and Golfito 1:200,000-scale quadrangles, Costa Rica, was produced to help stimulate the growth of the Costa Rican mining industry and, thus, to benefit the economy of the country. As a result of the geochemical data presented in the Atlas, future exploration for metallic minerals in Costa Rica can be focused on specific areas that have the highest potential for mineralization. Stream-sediment samples were collected from drainage basins within the two quadrangles. These samples were analyzed for 50 elements and the results were displayed as computer-generated color maps. Each map shows the variation in abundance of a single element within the quadrangle. Basic statistics, geological and cultural data are included as insets in each map to assist in interpretation. In the Golfito quadrangle, the geochemical data do not clearly indicate undiscovered gold mineralization. The areas known to contain placer (alluvial) gold are heavily affected by mining activity. Statistical treatment of the geochemical data is necessary before it will be possible to determine the gold potential of this quadrangle. In San Jose quadrangle, gold and the pathfinder elements, arsenic and antimony, are indicators of the gold mineralization characteristic of the Costa Rican gold district located in the Tilaran-Montes del Aguacate Range. This work shows that high concentrations of these elements occur in samples collected downstream from active gold mines. More importantly, the high concentrations of gold, arsenic, and antimony in sediment samples from an area southeast of the known gold district suggest a previously unknown extension of the district. This postulated extension underlain by Tertiary volcanic rocks which host the gold deposits within the gold district. The geochemical data, displayed herein, also indicate that drainage basins north of Ciudad Quesada on the flanks of Volcan Platanar have high gold potential.

    Salt is a major determinant of population blood pressure levels. Salt intake in Costa Rica is above levels required for good health. With an increasing number of Costa Ricans visiting fast food restaurants, it is likely that fast-food is contributing to daily salt intake. Salt content data from seven popular fast food chains in Costa Rica were collected in January 2013. Products were classified into 10 categories. Mean salt content was compared between chains and categories. Statistical analysis was performed using Welch ANOVA and Tukey-Kramer HSD tests. Significant differences were found between companies; Subway products had lowest mean salt content (0.97 g/100 g; p food categories. Salt content in sandwiches ranged from 0.5 to 2.1 g/100 g. The high levels and wide variation in salt content of fast food products in Costa Rica suggest that salt reduction is likely to be technically feasible in many cases. With an increasing number of consumers purchasing fast foods, even small improvements in salt levels could produce important health gains.

  14. Active Subduction on Both Coasts of Costa Rica Does not Represent an Important Tsunami Hazard

    Science.gov (United States)

    Protti, M.; Gonzalez, V.

    2007-05-01

    Costa Rica, on the southern terminus of the Middle American Trench is being affected by active subduction on both, along the Pacific coast as well as on its Caribbean coast. Three main subduction segments can be recognized along the Pacific coast: 1) under northwestern Costa Rica, off Papagayo Gulf and Nicoya peninsula, the Cocos plate is subducting under the Caribbean plate; 2) under southern Costa Rica (Osa and Burica peninsulas) the Cocos plate subducts under the Panama Block and 3) in the central Pacific coast (between Nicoya and Osa peninsulas) the Cocos plate subducts under a shear zone that marks the transition between the Caribbean and the Cocos plate. Along the Caribbean coast, south of Puerto Limon, the Caribbean plate subducts under the Panama block. Large subduction earthquakes occur under the Nicoya peninsula, Osa peninsula and south of Limon. Most of the rupture area of these large events lies below land so the deformation of the ocean floor is minimal and therefore the tsunamis they generate are small. No large subduction earthquakes occur under the central Pacific coast of Costa Rica due to the subduction of small sea mounts that act as small asperities without potential to accumulate large amounts of slip. For this reason the region between Nicoya and Osa peninsulas is not an important tsunamigenic zone.

    Full Text Available In 1999 a massive regularization of Central American migrants was realized in Costa Rica and later the whole country population was quantified, the kind of public insurance and the way healthcare services are use among other things, by a population census and home survey during 2000. Based on evidence found in investigations that were realized during those years, about the impact that the immigration has had in the Costa Rican Social Security organization, the author concludes that the immigrant does not contribute unfavorably to the Institutional pension system, that they use the hospital and urgency services less than the natives, they use the preventive medicine more and they has adopted the Costa Rican usual practices of avoidance the obligatory pays to the Caja Costarricense de Seguro Social, which is the most important public institution of healthcare services in the country.

  15. Differential DNA methylation and lymphocyte proportions in a Costa Rican high longevity region.

    2017-01-01

    The Nicoya Peninsula in Costa Rica has one of the highest old-age life expectancies in the world, but the underlying biological mechanisms of this longevity are not well understood. As DNA methylation is hypothesized to be a component of biological aging, we focused on this malleable epigenetic mark to determine its association with current residence in Nicoya versus elsewhere in Costa Rica. Examining a population's unique DNA methylation pattern allows us to differentiate hallmarks of longevity from individual stochastic variation. These differences may be characteristic of a combination of social, biological, and environmental contexts. In a cross-sectional subsample of the Costa Rican Longevity and Healthy Aging Study, we compared whole blood DNA methylation profiles of residents from Nicoya (n = 48) and non-Nicoya (other Costa Rican regions, n = 47) using the Infinium HumanMethylation450 microarray. We observed a number of differences that may be markers of delayed aging, such as bioinformatically derived differential CD8+ T cell proportions. Additionally, both site- and region-specific analyses revealed DNA methylation patterns unique to Nicoyans. We also observed lower overall variability in DNA methylation in the Nicoyan population, another hallmark of younger biological age. Nicoyans represent an interesting group of individuals who may possess unique immune cell proportions as well as distinct differences in their epigenome, at the level of DNA methylation.
