    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. O aumento da ocupação costeira inicia um processo de impacto para as florestas de mangue e a disponibilidade de seus recursos.

    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.

    Nanotubes are generally not perfectly straight cylinders and the local curvature can influence transport properties. As shown by da Costa [1], charged particles moving on a curved surface experience an effective potential which modifies their dynamics. In this paper, we solve a one-electron Schrödinger equation in a distorted nanotube with open boundary conditions. We find that the deformations may open bandgaps suggesting their use in the design of nanotube- based electronic devices.

    John Chalmers DaCosta was an influential chairman and the first Samuel D. Gross Professor of Surgery at Jefferson Medical College in Philadelphia. He was well known throughout the field as a skilled surgeon, passionate speaker, and exceptional writer. In addition to countless accomplishments during his career, DaCosta was deeply dedicated to the preservation and commemoration of surgical history. This ideology was exemplified when he set out on a mission to recover the old wooden operating table used by many of his iconic mentors including Samuel D. Gross, Joseph Pancoast, and William W. Keen. This table was originally used for surgical demonstrations and anatomy lessons in a lecture room of the Ely Building and later in the great amphitheater of the Jefferson Sansom Street Hospital. It was found forgotten in the basement of the College Building and was promptly refurbished, donned with dedicatory plaques, and returned to its honored position in the medical college. Dr. DaCosta also contributed a detailed article recalling the history of the table and the notable leaders in surgery who taught and practiced on its surface. The old table currently stands proudly in the entranceway of the Department of Surgery where it will remain as a cherished symbol of the early beginnings of surgical practice and education.

    The influence of suspended bottom material (0-25 mg/l) and algal cells (Phaeodactylum tricornutum) (0-500 .mu.g dry org wt[organic weight]/l) on clearance, growth and energetics in S. subtruncata (da Costa) was studied. Clearance and respiration rate were independent of concentrations of algae...... and suspended bottom material. Algal ingestion rate was proportional to algal concentration and independent of the concentration of suspended bottom material. Growth rate increased with algal concentration and was further increased by 10-110% by adding suspended bottom material. The positive effect of suspended...... bottom material on growth is due to a higher efficiency of assimilation of the ingested algae and/or the utilization of organic matter in the suspended bottom material. The efficiency of algal assimilation decreased from 76% at a low (150 .mu.g dry org wt/l) to 33% at a high (500 .mu.g) algal...

    The third meeting organised by the European Federation of Biotechnology (EFB) on advances in Applied Synthetic Biotechnology in Europe (ASBE) was held in Costa da Caparica, Portugal, in February 2016. Abundant novel applications in synthetic biology were described in the six sessions of the meeting, which was divided into technology and tools for synthetic biology (I, II and III), bionanoscience, biosynthetic pathways and enzyme synthetic biology, and metabolic engineering and chemical manufacturing. The meeting presented numerous methods for the development of novel synthetic strains, synthetic biological tools and synthetic biology applications. With the aid of synthetic biology, production costs of chemicals, metabolites and food products are expected to decrease, by generating sustainable biochemical production of such resources. Also, such synthetic biological advances could be applied for medical purposes, as in pharmaceuticals and for biosensors. Recurrent, linked themes throughout the meeting were the shortage of resources, the world's transition into a bioeconomy, and how synthetic biology is helping tackle these issues through cutting-edge technologies. While there are still limitations in synthetic biology research, innovation is propelling the development of technology, the standardisation of synthetic biological tools and the use of suitable host organisms. These developments are laying a foundation to providing a future where cutting-edge research could generate potential solutions to society's pressing issues, thus incentivising a transition into a bioeconomy.

    diferença marcante foi detectada na composição e abundância das espécies, bem como na riqueza, equitabilidade e heterogeneidade entre os locais. A distribuição de abundância de espécies encontrada ajustou-se a uma distribuição teórica lognormal nos três manguezais. A riqueza de espécies observada e o desempenho de estimadores de riqueza de espécies mostraram uma inesperada alta diversidade, considerando a baixa diversidade florística e as condições hostis do ambiente. A respeito da composição e abundância de espécies, as assembléias de drosofilídeos dos manguezais mostraram-se mais similares àquelas encontradas em ambientes relativamente mais abertos, com grande dominância de espécies exóticas. Finalmente, considerando-se a aparente escassez de sítios de alimentação e oviposição do ambiente, sugere-se que os manguezais estejam agindo como "sink habitats" para as populações de drosofilídeos.

    The bacterial communities in two different shoreline matrices, rocks and sand, from the Costa da Morte, northwestern Spain, were investigated 12 months after being affected by the Prestige oil spill. Culture-based and culture-independent approaches were used to compare the bacterial diversity present in these environments with that at a nonoiled site. A long-term effect of fuel on the microbial communities in the oiled sand and rock was suggested by the higher proportion of alkane and polyaromatic hydrocarbon (PAH) degraders and the differences in denaturing gradient gel electrophoresis patterns compared with those of the reference site. Members of the classes Alphaproteobacteria and Actinobacteria were the prevailing groups of bacteria detected in both matrices, although the sand bacterial community exhibited higher species richness than the rock bacterial community did. Culture-dependent and -independent approaches suggested that the genus Rhodococcus could play a key role in the in situ degradation of the alkane fraction of the Prestige fuel together with other members of the suborder Corynebacterineae. Moreover, other members of this suborder, such as Mycobacterium spp., together with Sphingomonadaceae bacteria (mainly Lutibacterium anuloederans), were related as well to the degradation of the aromatic fraction of the Prestige fuel. The multiapproach methodology applied in the present study allowed us to assess the complexity of autochthonous microbial communities related to the degradation of heavy fuel from the Prestige and to isolate some of their components for a further physiological study. Since several Corynebacterineae members related to the degradation of alkanes and PAHs were frequently detected in this and other supralittoral environments affected by the Prestige oil spill along the northwestern Spanish coast, the addition of mycolic acids to bioremediation amendments is proposed to favor the presence of these degraders in long-term fuel pollution

    Spinocerebellar ataxia 36 has been recently described in Japanese families as a new type of spinocerebellar ataxia with motor neuron signs. It is caused by a GGCCTG repeat expansion in intron 1 of NOP56. Family interview and document research allowed us to reconstruct two extensive, multigenerational kindreds stemming from the same village (Costa da Morte in Galicia, Spain), in the 17th century. We found the presence of the spinocerebellar ataxia 36 mutation co-segregating with disease in these families in whom we had previously identified an ∼0.8 Mb linkage region to chromosome 20 p. Subsequent screening revealed the NOP56 expansion in eight additional Galician ataxia kindreds. While normal alleles contain 5–14 hexanucleotide repeats, expanded alleles range from ∼650 to 2500 repeats, within a shared haplotype. Further expansion of repeat size was frequent, especially upon paternal transmission, while instances of allele contraction were observed in maternal transmissions. We found a total of 63 individuals carrying the mutation, 44 of whom were confirmed to be clinically affected; over 400 people are at risk. We describe here the detailed clinical picture, consisting of a late-onset, slowly progressive cerebellar syndrome with variable eye movement abnormalities and sensorineural hearing loss. There were signs of denervation in the tongue, as well as mild pyramidal signs, but otherwise no signs of classical amyotrophic lateral sclerosis. Magnetic resonance imaging findings were consistent with the clinical course, showing atrophy of the cerebellar vermis in initial stages, later evolving to a pattern of olivo-ponto-cerebellar atrophy. We estimated the origin of the founder mutation in Galicia to have occurred ∼1275 years ago. Out of 160 Galician families with spinocerebellar ataxia, 10 (6.3%) were found to have spinocerebellar ataxia 36, while 15 (9.4%) showed other of the routinely tested dominant spinocerebellar ataxia types.

    Full Text Available El uso de plaguicidas en los países en desarrollo es extenso en cantidad y en tiempo. Un gran porcentaje de lo que se aplica queda en el entorno y en los organismos que ahí habitan, lo que acarrea problemas de contaminación ambiental y deterioro de la salud de las personas que están en contacto con ellos. Los efectos se pueden manifestar a corto o a largo plazo y los síntomas varían desde un dolor de cabeza hasta el desarrollo de cáncer. La mayoría de los estudios en esta área se han orientado hacia los efectos agudos o crónicos y recientemente se inicia el estudio del efecto genotóxico de los plaguicidas. En e1 presente trabajo se evaluó el efecto genotóxico de los plaguicidas utilizados en las empacadoras de banano, usando como marcador biológico la electroforesis de células únicas (conocido como ensayo cometa en linfocitos aislados de sangre periférica. La población en estudio correspondió a 30 trabajadoras expuestas a plaguicidas, procedentes de 15 fincas bananeras y 28 mujeres sin antecedentes de exposición ocupacional a plaguicidas, de la misma área geográfica. Las trabajadoras que tenían entre cinco y quince años de trabajo presentaron mayor daño en la hebra sencilla del ADN (R² =0.12. Se desconoce si este efecto se debe a los plaguicidas que se utilizan actualmente o a plaguicidas empleados en el pasado. Tampoco fue posible correlacionar las dosis y las frecuencias de exposición a los plaguicidas con el daño al ADN, debido a que no existe un registro histórico sobre los productos empleados en el cultivo de banano, no se sabe por cuánto tiempo y las épocas en que fueron utilizados.

    Full Text Available Reports on ectoparasites on dogs in Central America are scarce. The aim of this study was to identify flea, louse and tick species infesting dogs in home environments on the Caribbean slope of Costa Rica, and determine their frequency and coexistence. Ectoparasites were collected from dogs in 83 rural homes at five study sites. Specimens were identified and separated according to species. Fleas were the most common ectoparasite (G = 22,217, DF = 8, p = 0.004. Ctenocephalides felis and Pulex simulans were found in 83% and 55% of the homes with ectoparasites, respectively. Trichodectes canis (13%, Heterodoxus spiniger (10%, Rhipicephalus sanguineus (18%, Rhipicephalus (Boophilus microplus (5% and Amblyomma ovale (8% were also present. More than one species was collected in most cases (66%, and the most common combination was C. felis and P. simulans (59% of homes with fleas. The high frequency of P. simulans emphasizes the need for adequate identification. This was the first study involving different ectoparasites of dogs in Costa Rica, as well as the first report of T. canis in this country. The relative frequency and coexistence of these ectoparasites in the home environment may have implications for animal and human health.Relatos de ectoparasitos em cães da América Central são escassos.

Todos os mosquitos foram coletados utilizando-se iscas humanas. O máximo de atividade ocorre nas horas crepusculares de manhã e da tarde (5:30 às 6:30 e 18:00 às 19:00 h. No período noturno, a atividade intradomiciliar é muito baixa, sendo ausente no peridomicílio durante o dia. O estado de desenvolvimento ovariano de fêmeas, coletadas nas horas de atividade máxima, mostrou a existência de duas populações de mosquitos: uma, na sua maioria constituída de indivíduos jovens, que procuram seu alimento nas horas da tarde; e uma outra, composta por indivíduos mais velhos, que procuram seu alimento nas horas da manhã. O estudo da variação sazonal mostrou que as populações são menores nos meses de pouca precipitação; na medida em que vai aumentando o índice pluviométrico cresce o número de mosquitos. Discutiu-se a relação existente entre a presença das populações de mosquitos com a prevalência de maláia no homem, sugerindo-se que A. neivai seja a responsável pela transmissão da malária na zona estudada.At Charambirá, a village in Istmina county, Department of Chocó, on the Pacific Coast of Colombia, malaria is endemic and is associated with large populations of Anopheles (Kerteszia neivai, which breed, in water which collects in epiphytic plants of the Bromeliaceae family, very abundant on mangrove trees.

    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.

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.

Este estudo teve por objetivo levantar as espécies bentônicas (com ênfase nos cnidários no topo dos recifes emersos da Área de Proteção Ambiental (APA Costa dos Corais, bem como calcular e comparar sua porcentagem de cobertura. Foram realizados transectos em linha contínuos, em seis praias da referida APA, em três regiões da plataforma recifal e com quatro réplicas para cada região. Os resultados mostraram maior cobertura de algas em todas as praias, com exceção de Tamandaré/PE. Entre os cnidários os zoantídeos predominaram, mas se registrou, também, a ocorrência dos corais escleractíneos Siderastrea stellata e Favia gravida. Outros organismos encontrados foram os poríferos, o molusco Brachidontes exustus e o equinodermo Echinometra lucunter. Foi observada ocorrência de branqueamento nas duas espécies de coral encontradas (em todas as praias visitadas e no zoantídeo Palythoa caribaeorum. De forma geral, os organismos registrados se caracterizaram pela resistência às condições instáveis da plataforma recifal. Além disso, as análises de agrupamento mostraram que fatores como o aporte de rios e o impacto antrópico exercem substancial influência na caracterização da cobertura bentônica da plataforma recifal, sobrepondo-se até mesmo à proximidade geográfica de áreas.

Widespread questions have been raised concerning the quality of services provided at birthing centers by obstetric nurses. The results of the current study were: 11.4% maternal transfer rate; 2.2% cesarean sections; 1.2% neonatal ICU admissions; and 1% 5-minute Apgar scores below 7. Delivery dystocia and the request for epidural anesthesia were the main reasons for maternal transfer, and respiratory distress was the main cause of neonatal ICU admission. Corrected neonatal mortality was 2 per 1,000 live births. The results at this birthing center did not differ significantly from those in a review of the international literature. The most striking finding was the low cesarean rate. Comparative studies and more comprehensive national data on low-risk gestations are needed.

    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.

Com o objetivo de caracterizar os ambientes de sedimentação de acordo com a granulometria e com o processo de evolução quaternária ao longo do litoral do Estado de São Paulo, foram estudados solos de 14 manguezais. As análises granulométricas foram realizadas nas camadas de 0-20 e 60-80 cm de profundidade, determinando as frações argila, silte, areia total e cinco frações da areia. Realizaram-se datações 14C por cintilação líquida, espectrometria de massa acoplada a acelerador de partículas na fração humina da matéria orgânica e por termoluminescência em grãos de quartzo, para amostras de diferentes camadas dos manguezais amostrados.

    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.

We have, for this analisys, looked over the works of Alonso 2008, of Oliveira 1999 and Carvalho 2003, by considering they bring up relevant contributions for the understanding of the histories of vivid ideas present between precedent years and the first decades of the Republic Proclaimation. The three works eventhough as of distinct objects and objectives, reject interpretation that, on one aspect, deal with the intelectual Republic ambience by means of intelectual tipologies clivages which would have been passively absorving european and american theories and, on the other hand, the ones that are stressed by studies that approach individual actions commited to the holding on ahead its ideological collors. These authors, on the contrary, understand that individuals are involved in determined cultural ambiences built up from sociability nets and by the running ideas repertory and, as to this very circusntance, they have different political and intelectual ways of acting by in a large scale, conditioning these factors to the possibilities of acting. So in this article the effort is trying to fix connectives amomg some elements of cultural ambience within the previous years to the Republic and relating them to the political and intelectual ways of acting that have enabled the educational information for the educator from Minas Gerais State. This analitycal movement, by itself had demanded that we should have resorted to some of the theoretical formulations of Antonio Gramsci 1975 as to the action senses of the intellectuals, as means of understanding them from the context and as the possibilities of acting are concerned, that have enabled the educator from Minas the achieving of their intents.

    Two batches of smoked, semi-hard (ripened for 45 d) San Simón da Costa cow's milk cheeses with Protected Designation of Origin were used to investigate the chemical, biochemical, and sensorial parameters that may be affected by modified-atmosphere packaging. Cheeses were packaged for 45 d as follows: vacuum packaging, packaging in 100% N(2), packaging in a gas mixture of 20% CO(2)/80% N(2), and packaging in a gas mixture of 50% CO(2)/50% N(2). The San Simón da Costa cheeses were characterized by high contents of lactic, oxalic, and citric organic acids. The main free amino acids found were isoleucine, phenylalanine, serine, valine, lysine, and glutamic acid, and the most abundant volatile compounds included ethanol, diacetyl, 2-butanol, isopropyl alcohol, furfural, acetaldehyde, 2-butanone, acetone, and 2-methylfuran. Modified atmospheres appeared to alter the ripening processes by affecting lipolysis, as indicated by the lower concentrations of butyric and propionic acids compared with control cheeses. In addition, modified-atmosphere packaging altered the proteolysis processes, yielding higher amounts of branched-chain alcohols. The results revealed that storage under modified atmosphere contributes to the accumulation of several compounds probably derived from smoke, including aldehydes such as 2-furancarboxaldehyde (furfural), alcohols such as 2-methoxyphenol (guaiacol), ketones such as 2-cyclopenten-1-one, and esters such as methyl furancarboxylate, which were negatively correlated with flavor. Vacuum packaging was the most useful technique in terms of preserving the sensory quality of San Simón da Costa Protected Designation of Origin cheeses. Considering the current demands for packaged portions of food at the distribution and retail levels and the potential health risks associated with some smoke-derived compounds usually present in some smoked foods, the results obtained in this study may be of special interest to the cheese industry.

    Full Text Available O trabalho avaliou a separabilidade de classes de água, a partir de técnicas de análises da reflectância de superfície, com dados medidos em campo e imagens multiespectrais adquiridas em nível orbital. A área de estudo foi o reservatório Rodolfo Costa e Silva, localizado na região central do Rio Grande do Sul. A metodologia foi baseada na coleta de dados in situ – total de sólidos em suspensão, clorofila (a, b, c, transparência da água e espectros de reflectância bidirecional – em 21 pontos amostrais no dia 16 de maio de 2006. A técnica de remoção do contínuo foi aplicada aos espectros de campo em quatro intervalos de bandas de absorção: 400-550nm, 610-640nm, 650-680nm e 580-700nm. Os parâmetros de remoção do contínuo das bandas de absorção analisados foram: profundidade, área e largura. Verificou-se que os parâmetros de profundidade, área e a largura da banda de absorção não apresentaram potencial de separabilidade em classes espectrais relacionadas à pequena variação na concentração dos componentes opticamente ativos na água. Imagens CBERS-2/CCD e Landsat 5/TM adquiridas em datas próximas à atividade de campo foram corrigidas dos efeitos atmosféricos e classificadas. Os resultados das classificações não apresentaram correlações significativas com os parâmetros de qualidade da água, a fim de proporcionar uma caracterização espectral das classes de água ou compartimentos. A dificuldade no estabelecimento de relações entre os parâmetros de reflectância espectral e qualidade da água foi devida, principalmente, à baixa variabilidade dos componentes opticamente ativos na água do Reservatório Rodolfo Costa e Silva. Neste caso, as análises espectrais testadas neste trabalho não foram sensíveis às pequenas variações observadas por meio dos dados de campo.

    Estudou-se o efeito da temperatura de incubação sobre o crescimento vegetativo, esporulação e morfologia da colônia do fungo Colletotrichum gossypii South. var. cephalosporioides Costa, em substrato de batata + dextrose + agar, pH 5,6. O delineamento experimental usado foi o de blocos casualizados e as temperaturas variaram de 12 a 33°C, a intervalos de 3° C. Concluiu-se que a temperatura de incubação afeta notavelmente o crescimento vegetativo, a esporulação e a morfologia da colônia do fungo. Temperaturas acima da faixa ótima provocaram modificações mais acentuadas sobre o crescimento miceliano, esporulação e aspecto morfológico, do que temperaturas baixas. Conídios produzidos em temperaturas extremas, 12 a 33°C, mostraram-se mais curtos que os dos demais tratamentos. A incubação à temperatura de 27°C é a mais recomendável para produção de inóculos em quantidade.

    In this work, the effect of temperature of incubation on the vegetative growth, sporulation and morphology of the colony of the fungus colletotrichum gossypii South. var. cephalosporioides Costa in substrate containing potato + dextrose + agar pH 5.6, was studied. The experimental design used was that of randomized blocks, with temperatures varying from 12 to 33 degrees centigrades, at intervals of 3°C. It was concluded that the temperature of incubation notably affects the vegetative growth, sporulation and morphology of the colony of this fungus. Temperatures above the optimum range caused greater changes in mycelial, sporulation an morphology of the colony than temperatures below this range. Conidia produced at l2 and 33°C were shown to be shorter than those in other treatments. The temperature of incubation recommended for inocule production was 27°C.

    Full Text Available Este artigo utiliza o método descritivo para analisar as origens e o caráter aparentemente intratável, mas evitável, dos fatores ancilares que implicaram a derrocada da Costa do Marfim, que já foi uma ilha de estabilidade política, uma vitrine de prosperidade econômica e de sucesso em uma África Ocidental mergulhada em guerras civis. 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.

    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.

    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.

    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

    Full Text Available O recrutamento larval e o crescimento de Teredinidae na região entremarés do manguezal da Praia Dura, Ubatuba, SP, foi acompanhado durante doze meses (08/84 a 08/85 utilizando coletores construídos com madeira de mangue. O tempo decorrido para se detectar a presença dos primeiros Teredinidae foi de aproximadamente sete meses após o início do experimento e o número de indivíduos por coletor foi muito reduzido no período de amostragem. Esses resultados contrastam com os obtidos por outros autores que instalaram coletores em ambiente marinho, mas são semelhantes aos obtidos por autores que instalaram coletores em regiões estuarinas do litoral brasileiro. Essas diferenças nos resultados talvez possam ser explicadas pelo fato da salinidade ser mais baixa e mais variável nos estuários que no ambiente marinho. A análise dos dados sobre o recrutamento larval, permite concluir que a espécie mais abundante foi Nausitora fustieula (Jeffreys, 1860, com principal época de instalação em março e taxa inicial de crescimento de 1,86 mm/day. As outras espécies de Teredinidae, Bankiaflmbriatula Moll & Roch, 1931, Bankia roehi Moll, 1931 e Neoteredo reynei (Bartsch, 1920, apresentaram pequeno número de indivíduos e em função disso, não foi possível determinar suas épocas de instalação e respectivas taxas de crescimento.The larval settlement and growth of Teredinidae in the intertidal region of the Praia Dura mangrove, Ubatuba, SP, were undertaken during one year (08/84 to 08/85 using colectors made from mangrove wood.

    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

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

Porém, antes de efetivar ações em Educação Ambiental, faz-se necessária uma diagnose que permita conhecer as percepções do corpo docente e discente. Assim sendo, fundamentado na Teoria das Representações Sociais de Serge Moscovici (1961 e utilizando o software Evoc, buscou-se identificar as representações sociais sobre o ecossistema manguezal dos alunos e professores do Ensino Fundamental da Escola, com a intenção de oferecer subsídios que auxiliem na Educação Ambiental voltada para a conservação do ecossistema local. Para identificar tais representações, utilizou-se uma pesquisa qualitativa com 92% dos professores e 25% dos alunos que compõem o Ensino Fundamental da Escola. Por meio das representações sociais dos professores, percebeu-se que, apesar de conhecerem o ecossistema manguezal, eles não conhecem o Parque dos Manguezais assim como os pressupostos da Educação Ambiental, necessitando assim de informações que os auxiliem nesse sentido pois suas representações estão voltadas para uma categoria naturalista, ou seja, a visão da natureza que se deve apreciar, cuidar e respeitar, mas que desconsidera o homem como parte do contexto. Quanto aos alunos, apesar de não terem conhecimentos sistêmicos a respeito do manguezal, eles conhecem bem o Parque dos Manguezais e suas representações estão voltadas para a preocupação com a poluição.The Municipal School Karla Patricia, located in a mangrove area called Park of the Manguezais, in Recife, Pernambuco, exists, among other functions, to contribute to the conservation of the park, through the Environmental Education.

    Full Text Available The behavioral patterns of the estuarine dolphin, Sotalia guianensis (P. 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. Dois padrões comportamentais comparáveis e facilmente reconhecíveis foram considerados: deslocamento e forrageamento

    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.

Foi desenvolvido um método objetivo para obter as datas, a localização e a intensidade dos ciclones, o que permitiu gerar compostos de algumas variáveis meteorológicas. Os resultados mostraram que em média ocorreram 17 casos de ciclones entre os meses de outubro a abril e que o período de vida dentro da região de estudo chegou até a 8 dias em alguns casos. O período de out/08 a abr/09 chama atenção por ter apresentado 27 casos. Os compostos para o período mostraram que a combinação de difluência no escoamento em altos níveis, associada a um cavado em médios níveis e a presença de anomalias positivas do vento zonal são favoráveis à formação de ciclones no Atlântico Sul, próximo à costa das Regiões Sul e Sudeste do país. A convergência do escoamento em baixos níveis é decisiva para estimular a ciclogênese na região. O estudo de caso mostrou uma aplicação da ferramenta desenvolvida que pode ter utilidade no aperfeiçoamento dos modelos numéricos de previsão desse tipo de sistema meteorológico.

    Costa Rica is a rich country in natural resources that can be taken in advantage for power aims, specially the hydraulic and biomass. Nevertheless its development has been based on the oil derivatives, resource that they do not have. The power resources of this country, the oil supply, the demand of oil derivatives are mentioned, the installed capacity and an evaluation is made of the prices of fuels in this country. [Spanish] Costa Rica es un pais rico en recursos naturales que pueden ser aprovechados con fines energeticos, especialmente los hidraulicos y los biomasicos.

    Full Text Available Utilizando datos del Registro Nacional de defunciones de los años 1996-2005 se calcularon las tasas de mortalidad estandarizadas por edad para personas nacidas en Nicaragua versus personas nacidas en Costa Rica. Así mismo, utilizando modelos de regresión binomial se determinaron los riesgos relativos de mortalidad de los inmigrantes nicaragüenses versus personas nativas de Costa Rica con ajustes por edad, urbanización, desempleo, pobreza, educación y segregación residencial. Los hombres y mujeres nacidos en Nicaragua tuvieron un riesgo reducido de mortalidad de 32% y 34% respectivamente con relación a sus contrapartes nacidas en Costa Rica. 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

    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

    Full Text Available O presente trabalho teve por objetivos investigar o número de capturas e o controle do morcego hematófago Desmodus rotundus, em pequenas propriedades localizadas no município de Cedral no estado do Maranhão, que foi escolhido por ter sido efetuado o maior número de capturas do estado, sendo todas ao redor de currais. O controle oficial é realizado pela aplicação de pasta vampiricida de uso tópico a base de warfarina a 2%. Para o estudo foram utilizadas fichas de controle de morcegos hematófagos capturados em currais, como também, foi aplicado um questionário a campo para identificação dos locais com maior número de capturas. No período de 2005 a 2010 foram estudados os resultados de 223 buscas ativas por D. rotundus, em 101 propriedades. Foi capturado um total de 408 morcegos hematófagos, distribuídos em 190 das 223 buscas. Em todos os espécimes de D. rotundus capturados foi realizado o tratamento, que consistiu na aplicação da pasta vampiricida, no dorso do animal. Nas propriedades estudadas, verificou-se que dos 754 animais expostos, 344 foram agredidos. Destes, os bovinos foram a maior oferta de alimento aos Desmodus (49%, seguidos dos equídeos (18%, aves (15%, suínos (9% e caprinos (8%. Apesar dos bovinos terem sido os mais atacados, em função do efetivo disponível, verificou-se uma preferência dos morcegos hematófagos por eqüídeos. As falhas nas capturas ocorreram onde havia poucos animais agredidos. Após análise de seis anos de realização do programa de controle com pasta vampiricida, verificou-se que a proporção de macho e fêmeas de D. rotundus capturados foi 1,08 machos para cada fêmea, o que demonstra que o tratamento foi mais efetivo nas fêmeas, uma vez que no primeiro ano do estudo, a proporção era de 1,21 fêmeas para cada macho. Verificou-se ainda que o controle foi realizado com sucesso em 95% das propriedades trabalhadas, com uma média de tempo de três anos de trabalho com até seis

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 Os metais traço apresentam grande toxicidade quando presentes em teores elevados nos organismos humano e animal. No ambiente aquático, alguns elementos formam compostos orgânicos que bioacumulam nos tecidos de organismos vivos. Os moluscos bivalves se destacam, pois possuem grande participação na dinâmica de contaminantes metálicos no ambiente marinho devido à capacidade de concentrá-los em níveis mais elevados que na água. Os mexilhões são moluscos bivalves que constituem bons indicadores de biodisponibilidade de metais, sendo amplamente utilizados como biomonitores em ecossistemas aquáticos. No Brasil, a espécie de mexilhão Perna perna é o mais cultivado devido à importância na alimentação de grande parte da população das regiões costeiras. Portanto, o consumo de mexilhões pode representar um risco à saúde humana quando proveniente de locais contaminados com metais traço, o que reforça a importância de se conhecer os teores desses elementos nos ambientes que fornecem alimento ao Homem. Devido à constante busca pela qualidade ambiental associada à utilização do mexilhão P. perna como biomonitor e como alimento, é importante conhecer o panorama de contaminação do território nacional a fim de auxiliar na prevenção de intoxicação por metais traço pelo consumo desse molusco por grande parte da população brasileira.Trace elements are considered toxic in high levels for human and animal organisms. In aquatic environment, some elements can form organic compounds and tend to bioaccumulate in organisms tissues. Bivalve mollusks participate on the metallic contaminants dynamics in aquatic environment due to capacity in concentrate trace elements in their soft tissues in higher levels than in water. Mussels are mollusks widely used as bioindicators of trace metal pollution in coastal areas because they can accumulate various elements as filter-feeders.

    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

With the aim of contributing to the knowledge of orange disease in mussel culture, the parasite life cycle was investigated. Experimental studies and monthly samples in the study area allowed the identification and characterization of the Bucephalus margaritae life cycle. Larvae and adults of B. margaritae were fixed in 5% formaldehyde, stained with Gomori’s trichrome, clarified in creosote and mounted in Canada balsam.

The metacercariae encysts in the gills and gill cavity of the second intermediate host, the blenniid Hypleurochilus fissicornis. The definitive host Menticirrhus americanus is infected ingesting blenniids parasitized with metacercariae. The high parasitological indexes of B. margaritae suggests that M. americanus and H. fissicornis act as the main definitive and intermediate hosts, respectively, in the trematode life cycle.

    Full Text Available En Costa Rica la enfermedad cardiovascular cobra en promedio 6 vidas por día, lo cual representa un aumento escalonado en los últimos años, debido en su mayoría a cambios en el estilo de vida del costarricense. Además, llama la atención, que factores de riesgo para enfermedad cardiovascular como son el fumado, obesidad infantil, alcoholismo, diabetes, dislipidemia e hipertensión han mostrado un incremento en su incidencia. Por lo tanto,se pretende realizar una revisión de los programas de detección y de atención temprana a nivel institucional, en lo que respecta a la Caja Costarricense de Seguro Social como ente responsable de llevar a cabo los mismos. El adecuado conocimiento y uso de los programas pretende una disminución en la morbimortalidad de la misma,y su aplicación se hace obligatoria para el manejo de pacientes en atención primaria.

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.

    The main cause of human exposure to artificial radiation corresponds to medical applications, so it is essential to reduce the dose to patients, workers and consequently the entire population [1]. Although there is no dose limit for patients, is necessary to reduce it to a minimum possible while still getting all the necessary diagnostic information, taking economic and social factors into account [2]. Based on this proposal, agencies such as the International Atomic Energy Agency has been dedicated to providing guidelines levels, whose function is to serve as standards for the optimization of the medical exposure [3]. This research was created as a preliminary survey with the claim of eventually determine the guidance levels in Costa Rica for three different studies of general radiology: Lumbar Spine-AP, Chest - PA and Thoracic Spine - AP (for screens with speeds of 400 and 800), and cranio-caudal study in mammography, applied to Costa Rica’s adult population, perform properly in the institutions of Caja Costarricense del Seguro Social (CCSS).

    Full Text Available La ehrlichiosis y la anaplasmosis son enfermedades infecciosas producidas por bacterias de la familia Anaplasmataceae y transmitidas por garrapatas. Ambas afectan, entre otras especies, al hombre, ocasionando sintomatología que puede ser asociada a un resfriado común o con signos clínicos compatibles con el dengue hemorrágico, patología que se presenta frecuentemente en Costa Rica. Tanto la ehrlichiosis como la anaplasmosis son consideradas también enfermedades de importancia en Medicina Veterinaria. A continuación se brinda una revisión sobre los hallazgos obtenidos en investigaciones realizadas en el país para determinar la presencia y distribución de Ehrlichia y Anaplasma en Costa Rica. Ehrlichia canis se encuentra ampliamente distribuida en el país y es la especie predominante en perros y garrapatas (Rhipicephalus sanguineus. Adicionalmente, se ha detectado, aunque en menor porcentaje, la presencia de Anaplasma platys y Anaplsma phagocytophilum en perros y sus garrapatas. También se ha determinado la presencia de A. phagocytophilum en un venado cola blanca, y de E. canis en humanos donadores de bancos de sangre mediante técnica serológica y molecular.

    Full Text Available El déficit fiscal es una de las variables macroeconómicas que ha adquirido mayor importancia desde la década de los años ochenta y particularmente en los años noventa, en la economía costarricense. Una consecuencia directa de la existencia de déficits fiscales sostenidos es la acumulación de una deuda pública creciente.Antes de los años ochenta el déficit fiscal en Costa Rica se cubrió fundamentalmente con deduda externa; la cual era de fácil acceso en los mercados financieros internacionales, ante la existencia de una sobre oferta de fondos prestables, generado por los petrodólares. Sin embargo, con la crisis económica que experimentó Costa Rica en los primeros años de la década pasada y con el endurecimiento del acceso al financiamiento externo, el país empezó a recurrir cada vez con más frecuencia al endeudamiento interno.

    The main cause of human exposure to artificial radiation corresponds to medical applications, so it is essential to reduce the dose to patients, workers and consequently the entire population [1]. Although there is no dose limit for patients, is necessary to reduce it to a minimum possible while still getting all the necessary diagnostic information, taking economic and social factors into account [2]. Based on this proposal, agencies such as the International Atomic Energy Agency has been dedicated to providing guidelines levels, whose function is to serve as standards for the optimization of the medical exposure [3]. This research was created as a preliminary survey with the claim of eventually determine the guidance levels in Costa Rica for three different studies of general radiology: Lumbar Spine-AP, Chest - PA and Thoracic Spine - AP (for screens with speeds of 400 and 800), and cranio-caudal study in mammography, applied to Costa Rica's adult population, perform properly in the institutions of Caja Costarricense del Seguro Social (CCSS).

    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).

    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

Sets of poles were vertically fixed in the riverbed at three sites along a decreasing salinity gradient, where they stayed for four months. The poles were collected and divided into upper, median, and lower segments, in agreement with different immersion regimes. An increase of 239% was obtained in the number of individuals when compared to a previous study in the same area using a different methodology. The species Teredo bartschi (Clapp, 1923, Nausitora fusticula (Jeffreys, 1860 and Bankia fimbriatula Moll & Roch, 1931 were registered in both studies, and the species Psiloteredo healdi (Bartsch, 1931 is here registered for the first time as occurring in that estuary. The species Neoteredo reynei (Bartsch, 1920, previously registered on tree branches of the mangrove habitat, was not found in the present work. Bankia fimbriatula, the most abundant species, did not show preference for any substratum but occurred significantly on the lower segment of the poles. N. fusticula, second in abundance, preferred to settle on poles of A. schaueriana and on any of the three segments. Aiming to assess the habitat variations, a more accurate study on teredinids diversity in mangrove ecosystems should be performed through a concomitant analysis from tree branches of the mangrove habitat, as well as from poles of mangrove trees or panels made of pine wood or mangrove trees wood.

    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.

    Full Text Available Bernardo Augusto Thiel (1850-1901 fue el segundo Obispo de Costa Rica (1880-1901 y desarrolló una obra tan impresionante como multifacética. En el campo eclesiástico le correspondió dirigir la Iglesia en un periodo de fuertes conflictos con los liberales, pero logró acuerdos institucionales satisfactorios en 1886, los cuales le permitieron dedicarse a reorganizar la diócesis y difundir con particular énfasis la nueva doctrina social de la iglesia iniciada, con la encíclica papal Rerum Novarum en 1891. En el campo de la investigación social se lo puede considerar como el primer demógrafo costarricense, el primer historiador de la Iglesia y el primer etnógrafo. De lo primero, da testimonio la Monografía de la población de Costa Rica en el siglo XIX que se vuelve a publicar en este número de Población y Salud en Mesoamérica. De lo segundo, da testimonio la amplia compilación de datos incluida en la serie de artículos: “Datos cronológicos para la historia eclesiástica de Costa Rica”, publicados originalmente en El mensajero del clero entre 1896 y 1901. El tercer aspecto queda cubierto por las visitas pastorales realizadas por Thiel a las zonas de pueblos indígenas entre 1882 y 1896; la amplia información recopilada en dichas visitas, disponible ahora en una transcripción completa (Herrera Sotillo, Ana Isabel, Monseñor Thiel en Costa Rica, Cartago, Editorial Tecnológica de Costa Rica, 2009, constituye una base de datos de valor inestimable. La Monografía de la población de Costa Rica en el siglo XIX es una obra valiosa, punto obligado de inicio de la demografía histórica del país. Mi propio trabajo (La población de Costa Rica, 1750-2000. Una historia experimental. San José, Editorial UCR, 2010 comenzó precisamente con una apreciación crítica de dicho trabajo. Aunque la Monografía ha sido reimpresa ya varias veces, consideramos importante que siempre esté al alcance de las nuevas generaciones de lectores, y es

    Full Text Available Este artículo aborda algunos de los retos conceptuales y metodológicos que identificó la Escuela de Psicología de la Universidad de Costa Rica para el estudio de la salud mental en Costa Rica con el fin de favorecer un debate académico. Presenta una breve reseña del trabajo realizado desde esta unidad académica en los últimos tres años y da cuenta del proceso de trabajo coordinado con otras instancias de la universidad, instituciones públicas, organismos y organizaciones de la sociedad civil a nivel nacional e internacional e identifica los principales nudos de discusión trabajados a nivel conceptual y metodológico. El primero de ellos se refiere a los alcances y las limitaciones al utilizar los términos salud mental, salud o bienestar; este último se trata de una propuesta novedosa en Costa Rica. En un segundo momento, se desarrolla el debate sobre la relevancia de los marcadores genéticos y los factores ambientales y sociales en el proceso de salud/enfermedad. Introduce los aportes de la epidemiología crítica y presenta los argumentos de por qué se considera oportuno realizar la Primera Encuesta Nacional de Salud Mental en Costa Rica, a pesar de una anticipada orientación metodológica por principios más tradicionales del enfoque psiquiátrico y de la epidemiología.

  5. Glaucoma in Costa Rica: Initial approaches

    Full Text Available Glaucoma is the second most frequent cause of irreversible blindness worldwide. Genetic factors have been implicated in the development of the disease. So far six loci (GLC1A-GLC1F and two genes (TIGR/MYOC and OPTN are involved in the development of juvenile (JOAG and adult onset or chronic primary open angle glaucoma (COAG, while two loci (GLC3A,GLC3B and one gene (CYP1B1 are known for primary congenital glaucoma (PCG. Here we summarize the results of the first genetic studies of glaucoma in Costa Rica. Nine families: 1 with JOAG, 1 with PCG and 7 with COAG were screened for mutations at the known genes. A10 bp duplication, 1546-1555dupTCATGCCACC, at the CYP1B1 gene, causes, in homozygous state, glaucoma in the consanguineous PCG family. This mutation has been found in different countries and generates an early stop codon that termitates protein synthesis 140 amino acids earlier than the normal allele. In exon 1 of the TIGR/MYOC the innocuous Arg76Lys variant was found in two of the COAG families. In the OPTN gene two variants in the coding region (Thr34Thr, Met 98Lys and 7 intronic changes were found in other Costa Rican glaucoma patients. One of the COAG families was chosen for a genome scan with 379 microsatellite markers and linkage analysis. LOD scores "suggestive" of linkage were obtained for several chromosomal regions. Evidence indicates that hereditary glaucoma in Costa Rica is highly heterogeneous and that further studies in the country will probably disclose some up to now unknown genes responsible for the disease. Rev. Biol. Trop. 52(3: 507-520. Epub 2004 Dic 15.El glaucoma es la segunda causa de ceguera irreversible en el mundo. El componente genético de algunos de los distintos tipos ha sido demostrado: seis loci (GLC1A-GLC1F y dos genes (TIGR/MYOC y OPTN se conocen, hasta ahora, como responsables de la aparición de glaucomas primarios de ángulo abierto tanto del tipo juvenil (JOAG como de l tipo de adultos (COAG.

    2008-08-01

    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. In recent years these phenomena have intensified both spatially and temporarily, discolorations occur almost uninterrupted; they are distributed for months and which extend along the

    Full Text Available RESUMENEste trabajo utiliza datos de las Encuestas Comparativas de Fecundidad de América Latina, así como de la Encuesta Mundial de Fecundidad para estudiar las tendencias y diferenciales en el espaciamiento de los nacimientos entre las mujeres alguna vez casadas en Costa Rica durante el período 1945-1974. 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. A good deal of attention is placed on the pace of fertility in threshold, early and late stages of the fertility decline that this country experienced during the sixties and early seventies. The results show a good deal of similarity in the tempo of reproduction across parities and geographical areas.However, an analysis of the background variables affecting birthspacing shows differences between urban and rural zones. Finally, it is postulated that the recent plateau in period rates may be a consequence of changes in the tempo of

Las estadísticas de los diferentes países apuntan a que se está convirtiendo en una epidemia que nos está asfixiando. La prevención de la revictimización, una política establecida en el Poder Judicial de Costa Rica desde hace más de diez años, dio como fruto la conformación de los equipos interdisciplinarios. Al inicio, estos abarcaron una serie de disciplinas tan disímiles entre sí, que comprendían tanto el derecho, como la medicina, la psicología, el trabajo social y la psiquiatría. Con el paso de los años los equipos se fueron reduciendo hasta quedar conformados por el psicólogo, el trabajador social y el médico forense, que asiste a una reunión semanal con ellos y en donde se discuten las diferentes conclusiones de las tres disciplinas. Hoy en día son equipos establecidos prácticamente en todas las cabeceras de provincia de nuestro país con funciones periciales muy específicas en el tratamiento legal de las causas de los delitos sexuales.Sexual Abuse is series of actitudes of a subject, Which he realize in detriment of other, usually younger, for his self satisfaction.

Combinar los pronósticos con mejor ajuste resulta útil especialmente para proyectar en tiempo real, mientras que los MiDaS muestran el mejor desempeño general: al incrementarse el horizonte su precisión disminuye levemente, su porcentaje de acierto de cambios en la tasa de variación del producto permanece estable y varios de ellos son insesgados. Los pronósticos de MiDaS simples con 9 y 12 rezagos resultaron insesgados para todos los horizontes y conjuntos de información evaluados, y son los que mostraron más diferencias significativas en capacidad de pronóstico con todos los demás modelos.

    Full Text Available The analysis of influence of harmonic interference on the phase error in the Costas circuit is carried out. Differential equations of the circuit are obtained. 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 La diabetes mellitus neonatal es un raro desorden metabólico usualmente desarrollado en las primeras 6 semanas de vida, secundario a un grupo de mutaciones y defectos del desarrollo pancreático que puede desembocar en una catástrofe clínica si no se identifica tempranamente; se divide en una variante transitoria y una permanente, siendo la primera la más frecuente, con cerca de un 60% de los casos. El manejo inicial de ambas variantes es la insulinoterapia intensiva, que en la variante transitoria puede suspenderse usualmente en los primeros meses de vida. El síndrome de disregulación inmunológica, poliendocrinopatía y enteropatía ligada a X (IPEX por sus siglas en inglés, es una causa extremadamente rara de la variante permanente, casi siempre mortal, caracterizada por un inmunocompromiso severo, enteropatía, diabetes y dermatitis.

    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.

Para ampliar los reportes oficiales de la comercialización de alimentos para perros se creó una base de datos que incluyó cantidad, costo, empaque y formulación durante el período 1998 a agosto del 2000. De 1995 a 1998 y de 1996 a 1999 la producción nacional incrementó un 90,4% y la importación un 42,56% respectivamente, ocupando los alimentos nacionales un 72% del tonelaje y un 70% del valor en dólares americanos. No fue posible determinar cuál es el empaque más comercializado, pero si que los alimentos extrusados son los que ocupan el primer lugar y que los alimentos recomendados para cachorros y adultos son los que más se comercializan. La ausencia de datos en las declaraciones sugiere la necesidad de incrementar el control en las mismas en caso de requerirse un estudio de mercado, ya que contrariamente a esta situación el mayor número de garantías inscritas corresponden separadamente para las fases de cachorros y adultos. Merece también atención que las garantías indican mayores porcentajes de proteína cruda que los recomendados por la AAFCO y que al menos 36 fórmulas son recomendadas para estados sanitarios específicos (p.e. para perros con problemas de alergias, cálculos renales, pérdidas de pelo, etc. sin que oficialmente se encuentre registrada ninguna fórmula medicada

    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.

El componente de servicios de salud incluye un sector público y uno privado. El sector público está dominado por la Caja Costarricense de Seguro Social (CCSS, institución autónoma encargada del financiamiento, compra y prestación de la mayoría de los servicios personales. 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. Dentro de las innovaciones relativamente recientes que se han implantado en Costa Rica destacan la implantación de los equipos básicos de atención integral de salud (EBAIS, la desconcentración de los hospitales y clínicas públicos, la introducción de los acuerdos de gestión y la creación de las Juntas de Salud.This paper describes the Costa Rican health system which provides health, water and sanitation services.

    2009-07-01

    la segunda mitad del Siglo XX: la revolución silenciosa en patrones reproductivos existentes desde siempre y que estaban apuntalados por normas religiosas, culturales y sociales que parecían en su momento inamovibles.El artículo tiene el mérito de ser el primer estudio serio que mostró que la natalidad en Costa Rica estaba cayendo en picada. Lo hizo en tiempos en que tirios y troyanos creían que una caída de esa magnitud no era posible en un país poco desarrollado y supuestamente muy católico como Costa Rica.La cuidadosa evaluación de las estadísticas de nacimientos del país incluida en la primera parte del artículo –referencia obligada desde entonces para todos quienes usamos estas estadísticas– le permite al autor hacer a un lado las objeciones de que la revolución reproductiva en curso era un espejismo de estadísticas falaces. Hace 40 años no era fácil hablar en público de métodos anticonceptivos o de la planificación familiar y menos en una universidad con fuertes sesgos ideológicos que veía estos asuntos como una conspiración del imperialismo yanqui. Esto se nota en el modo algo reticente en que Miguel aborda este tema en el artículo. Pero lo hace de manera sobria y con respaldo científico de datos, demostrando que la caída de la natalidad se debía a que entre las mujeres costarricenses se estaba difundiendo rápidamente el uso de anticonceptivos: estaban teniendo relaciones sexuales para fines distintos que la procreación, es decir de manera pecaminosa y en abierta desobediencia de las enseñanzas de la iglesia católica! Y aunque la anticoncepción –eufemísticamente rebautizada como “planificación familiar” primero y “salud reproductiva” más tarde – había recibido el espaldarazo del gobierno uno o dos años antes, el artículo muestra que el proceso se inició con anterioridad y de forma casi espontánea en la esfera privada con el apoyo de farmacias comerciales y médicos particulares exclusivamente.Hoy no nos

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.

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.

    Full Text Available Burkholderia glumae en el cultivo de arroz en Costa Rica. El objetivo de este trabajo fue determinar la presencia de Burkholderia glumae en arroz en Costa Rica. La bacteria Burkholderia glumae está asociada al cultivo del arroz en el que provoca la enfermedad llamada añublo bacterial. Bajo condiciones ambientales favorables, la densidad bacteriana aumenta, lo que provoca que, bajo un sistema de regulación denominado quorum sensing, se expresen sus mecanismos de virulencia mediante la activación de genes responsables para la síntesis de la toxoflavina, que bloquea el flujo de nutrientes, para la biogénesis de flagelos y la respuesta quimiotáctica, y la producción de la enzima catalasa. Las plantas desarrollan la sintomatología que finalmente conlleva a un vaneamiento del grano provocando pérdidas económicas importantes. Se investigó la situación referente a la contaminación del grano de arroz causado por esta bacteria en Costa Rica durante los años 2009 y 2010, mediante un convenio entre la Corporación Nacional Arrocera y el Laboratorio de Fitopatología del Centro de Investigación en Protección de Cultivos de la Universidad de Costa Rica. Se usó la metodología de PCR de punto final recomendada por investigadores del Centro Internacional de Agricultura Tropical en Colombia y se reforzó la identificación, por medio de técnicas de microbiología convencional. Se obtuvieron resultados que indican la presencia de la bacteria en Costa Rica, la primera información sobre la prevalencia de un fitopatógeno bacteriano de gran importancia para el sector arrocero.

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.

    Arkley Marques Bandeira

    Full Text Available Resumo Os padrões humanos de subsistência e/ou mobilidade podem estar refletidos no registro zooarqueológico dos sambaquis de manguezais estuarinos e outros ecótonos litorâneos. Em um domínio biogeográfico, tal como o manguezal e seus ecótonos associados, a disponibilidade de grande parte dos recursos animais pode aumentar em função da sazonalidade e do ciclo de vida dos seres vivos, e tornar-se mais acessível dentro de uma área de captação de recursos. Assim, o registro dos sambaquis, caracterizados por uma grande quantidade de restos de moluscos e peixes, em relação a outros táxons, pode indicar tanto um viés tafonômico, quanto questões relacionadas ao cálculo da biomassa em laboratório e/ou variações na subsistência humana em função das modificações da paisagem no ciclo anual. Este trabalho tem por objetivo contemplar as questões e as hipóteses sobre os padrões de mobilidade atrelados aos modelos de subsistência e à apropriação do ambiente por sociedades humanas pretéritas, nos Sambaquis do litoral maranhense, com especial ênfase ao sambaqui do Bacanga, inserido em um contexto de manguezal estuarino.

    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. Its therapeutic use has been rejected. Poisoning with this substance is not common because n Costa Rica its use is currently restricted to the elimination of street dogs practiced by sanitary personnel. The symptons, basically neuroogic and cardiorespiratory, require clinical and laboratory analysis, according to the present review of recent literature.

    2006-12-01

    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 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.

La bacteria Burkholderia glumae está asociada al cultivo del arroz en el que provoca la enfermedad llamada añublo bacterial. Bajo condiciones ambientales favorables, la densidad bacteriana aumenta, lo que provoca que, bajo un sistema de regulación denominado quorum sensing, se expresen sus mecanismos de virulencia mediante la activación de genes responsables para la síntesis de la toxoflavina, que bloquea el flujo de nutrientes, para la biogénesis de flagelos y la respuesta quimiotáctica, y la producción de la enzima catalasa. Las plantas desarrollan la sintomatología que finalmente conlleva a un vaneamiento del grano provocando pérdidas económicas importantes. Se investigó la situación referente a la contaminación del grano de arroz causado por esta bacteria en Costa Rica durante los años 2009 y 2010, mediante un convenio entre la Corporación Nacional Arrocera y el Laboratorio de Fitopatología del Centro de Investigación en Protección de Cultivos de la Universidad de Costa Rica. Se usó la metodología de PCR de punto final recomendada por investigadores del Centro Internacional de Agricultura Tropical en Colombia y se reforzó la identificación, por medio de técnicas de microbiología convencional. Se obtuvieron resultados que indican la presencia de la bacteria en Costa Rica, la primera información sobre la prevalencia de un fitopatógeno bacteriano de gran importancia para el sector arrocero.

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

    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.

    Full Text Available RESUMO As gramas halófitas Spartina alterniflora e Spartina densiflora são espécies bioengenheiras, que podem ser utilizadas para mitigação de áreas degradadas de marismas e manguezais, para o controle da erosão costeira e para estabilização de dragado depositado em regiões estuarinas e costeiras. O objetivo deste trabalho foi avaliar os efeitos da densidade de plantio e da adubação com nitrogênio (N e fósforo (P sobre mudas de propagação vegetativa destas duas espécies, crescendo em bandejas (0,15 m2; 7500 cm3. Para isto, foram realizados em estufa agrícola, não climatizada, dois experimentos nos anos de 2009 e 2011. Em 2009, apenas S. alterniflora foi cultivada, em duas densidades de plantios (133 e 400 mudas m-2 e com dois níveis de adição de nutrientes (sem adubação e com adição total de 50,8 gN m-2 e 16 gP m-2. Em 2011, bandejas com 80 mudas m-2 de ambas as espécies foram adubadas com razões 2N:1P, 6N:1P, 10N:1P e 14N:1P (adição total de 115 gN m-2. A adubação com NP estimulou a formação foliar e, em recipientes fertilizados, o número médio de hastes de S. alterniflora, após 80 dias, foi o dobro do observado nos recipientes-controle.

Materiales y Métodos: Se analizaron 35 muestras de queso fresco, adquiridas durante los meses de setiembre y octubre del 2010 en la zona de San Vito de Coto Brus. A cada muestra se le realizaron recuentos de coliformes totales, coliformes fecales y Staphylococcus aureus. Adicionalmente se analizó presencia/ausencia de Listeria monocytogenes en 25 gramos del producto. A las cepas identificadas como S. aureus se les realizó la prueba de sensibilidad a los antibióticos mediante el sistema automatizado Vitek y la interpretación de los datos se realizó siguiendo las pautas del Clinical and Laboratory Standards Institute antimicrobial susceptibility testing 2011. Adicional a esto se recolectaron datos acerca de la sensibilidad de las cepas de S. aureus aisladas e identificadas en el Hospital de San Vito de Coto Brus en el mismo período. Resultados: El promedio obtenido para el recuento de coliformes totales fue de 9,7 X 10(6 UFC/g, para coliformes fecales de 6,7 X 10(5 y para S. aureus de 2,8 X 10(5 UFC/g, obteniéndose un 83 % de muestras positivas por esta bacteria.

  10. 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.

    2008-01-01

    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.

Chegamos à conclusão que há graus de estragos acima dos verificados em publicações anteriores, os 7º, 8º, 9º e 10º graus de estragos, com desaparecimento de todas cinturas vegetais. Anotamos os assoreamentos; devido a aterros artificiais na vizinhança, a lama subiu muito, meio metro em 20 anos, ou seja 2,5 centímetros por ano. Apresentamos as alterações ecológicas resultantes do assoreamento, mostramos a mudança de vários nichos de alguns componentes do manguezal. Fizemos 4 mapas ecológicos, em local que constitui a média representativa do que se passou na Enseada de Inhaúma nesses últimos 5 anos. Chegamos a índices de recuperação de zonações do manguezal, como 60/1 para o Avicennietum; e nenhum para o Laguncularietum, comunidade de "mangues mansos" que está em regressão; Houve regeneração das populações de caranguejos Ucides e Cardisoma que voltaram a habitar a Ilha do Pinheiro. Mostramos uma correlação entre o guaiamu e a aroeira da praia, Schinus. Concluímos que: podem ser usadas as técnicas de recuperação de poluição para esses caranguejos e guaiamus, para a alimentação humana, assim como para peixes apanhados em alagados de manguezais poluídos. O material pescado no Rio de Janeiro, tendo algas do gênero Oscillatoria, apresenta um cheiro de urina pútrida, bem como outros cheiros, mas pode ser recuperado para a alimentação humana.

    Full Text Available The coral reef is an ecossystem which evokes great interest, for its beaury, species diversity and fisheries potential. The coast of Paraíba State, northeast Brazil, possesses several natural reefs and shipwrecks which are inhabited by a rich fish fauna. In order to survey the reef fish fauna of Paraíba State, a total of 118 dives, utilizing SCUBA diving techniques, were carriedoutin 27samplingpoints (depths: 0,5-66m, from February/1995 to May/1996. Specimens were collected whenever underwater identification was precluded. A total of 157 known species belonging to 59 families were found. Four unidentified species, one dasyatid, one haemulid, one scarid, and one labrid were recorded. Haemulidae was the most representative family in number of individuais, whereas Carangidae was the most speciose family. This paper is part of a broader study of the northeast Brazilian reef fishes.

    Full Text Available Se estudiaron las comunidades y arrecifes coralinos del Parque Nacional Marino Ballena (PNMB, en el Pacífico sur de Costa Rica, mediante tres transectos por sitio, de 10 m de largo cada uno y paralelos a la costa, utilizando una cuadrícula de 1 m2. Se encontró un total de 15 especies de corales (11 hermatípicas y 4 ahermatípicas, las que sumadas a informes previos para el parque hacen un total de 18 especies. El coral Porites lobata presentó la mayor cobertura coralina (36.5 ± 3.7% y fue el único presente en todos los sitios. Las otras especies de coral presentaron bajas coberturas (<10% y sólo fueron observadas en pocos sitios. El porcentaje de coral muerto fue de 1.8 ± 0.6% y el porcentaje de blanqueamiento (0.7 ± 0.2% está dado por P. lobata en un solo sitio. El PNMB y la Isla del Caño poseen el mayor número de especies de coral (18 especies de la región sur de Costa Rica; sin embargo, difieren en su composición. 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.

    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.

    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.

    Full Text Available Costa Rican natural ecosystems are among the most diverse in the world. For this reason, we isolated strains of the entomopathogenic bacteria Bacillus thuringiensis (Bt to determine their diversity, distribution and abundance. A total of 146 Bt strains were obtained from environmental samples collected from diverse natural ecosystems and life zones of Costa Rica. We recovered Bt strains from 71%, 63%, 61% and 54% of soil samples, fresh leaves, other substrates and leaf litter respectively. Bt was isolated in 65%of the samples collected in the humid tropical forest in national parks (Braulio Carrillo, Gandoca Manzanillo, Sierpe, Hitoy Cerere, and Cahuita, and in 59% of the samples collected in the dry tropical forest (Parque Nacional Marino las Baulas, Palo Verde and Santa Rosa. In the very humid tropical forest (Tortuguero Bt was isolated in 75% of the samples and in the very humid tropical forest transition perhumid (Cararait was found in 69% of the samples. The strains exhibit a diverse number, size and morphology of parasporal inclusion bodies: irregular (47%,oval (20%, bipyramidal (3%, bipyramidal and cubic (1%, bipyramidal, oval and irregular (5% and bipyramidal, oval and cubic crystals (2%. Strains isolated from Braulio Carrillo, Tortuguero and Cahuita, presented predominantly irregular crystals. On the other hand, more than 60% of the isolates from Térraba-Sierpe and Hitoy-Cerere had medium oval crystals. Strains from Gandoca-Manzanillo, Palo Verde and Carara presented mainly combinations of oval and irregular crystals. Nevertheless, the greatest diversity in crystal morphology was observed in those from Santa Rosa, Llanos del Río Medio Queso and Parque Marino las Baulas. Protein analyses of the crystal-spore preparations showed ä -endotoxin with diverse electrophoretic patterns, with molecular weights in the range of 20 to 160 kDa. Fifty six percent of the strains amplified with the cry2 primer, 54% with vip3, 20% with cry1, 9% with

    Full Text Available Cerca del 10% de la población costarricense padece de alguna minusvalía, producto del riego que conlleva el trabajo en sí mismo. Desde 1865 se han hecho acciones legislativas para atender la reparación del daño corporal de origen laboral, hasta que se llega a establecer la Ley de Riesgos del Trabajo en 1982. Dicha ley esta inspirada en los baremos de amplio uso. En el presente artículo se hace una exposición de la aplicación de dicho instrumento de valoración del daño corporal, en las diferentes instancias médico legales que operan en Costa Rica.About 10% of the Costa rican population suffers from some kind of handicap, product of the risk that work it self produces. Since 1865, legislatures include the reparation of physical damage produced by work. In 1982, the law of laboral risk is established. This law is inspired in the widely used baremes. This article exposes the aplication of baremes in the evaluation of physical damage in different Costa Rican veredicts.

    Full Text Available Epidemiological studies were conducted on malaria in three rural areas of the Amazon basin in the State of Rondônia: the town of Costa Marques, Forte Príncipe da Beira (Fort, and an immigrant settlement in the nearby forest. These studies were instituted to document the malaria problem and to describe the role of immigration on its distribution and prevalence. Hospital records in the town show that the number of malaria cases increased five fold from 1983 to 1987 and that the predominant malaria parasite changel from Plasmodium vivax to P. falciparum. Increased malaria followed increased immigration and colonization of the forest. A series of epidemiologic studies suggested the linkage between malaria and immigration as the prevalence of malaria was 1-2% at the Fort, a stable community, 8-9% at Costa Marques, a growing community, and 14-26% in the new settlements in the forest.Foram conduzidos estudos epidemiológicos de malária em três áreas rurais da Amazônia legal, no Estado de Rondônia: a cidade de Costa Marques, Forte Príncipe da Beira (Forte e uma colônia de imigrantes perto da floresta.

Os registros hospitalares na cidade mostram que o número de casos de malãria aumentou cinco vezes desde 1983 a 1987 e o parasita predominte da malária mudou do Plasmodium vivax para o P. falciparum. O aumento da malária foi seguido pelo crescimento da imigração e colonização da floresta. Uma série de estudos epidemiológicos sugeriu que há ligação entre malária e imigração uma vez que a prevalência da malária foi de 1-2% para o Forte, uma comunidade estável, 8-9% em Costa Marques, uma comunidade em crescimento, e 14-26% na nova colônia de imigrantes na floresta.

El ensayo cometa es una técnica simple, rápida y de bajo costo para la cuantificación de daños en el ADN, en términos de rupturas y sitios álcalilábiles, en la hebra simple del ADN de células individuales. Se expusieron linfocitos humanos a concentraciones de 0, 25, 50, 75 y 100 µg/ml de los plaguicidas, por 30 min a 37°C. Las células fueron embebidas en agarosa, se provocó la lisis de sus membranas citoplasmáticas y se sometieron a electroforesis alcalina durante 20 min a 25V. Por último, las preparaciones se neutralizaron y se deshidrataron, para el posterior teñido de las láminas con el fluorocromo y la visualización de los cometas en el microscopio de epifluorescencia. El clorpirifos y el imazalil inducen daños significativos en la hebra sencilla del ADN en forma dependiente de la concentración, siendo el clorpirifos el mayor inductor de rupturas en el material genético. Estos resultados indican que ambos se comportan como compuestos genotóxicos in vitro. El fungicida tiabendazol mostró resultados negativos en las concentraciones empleadas.Genotoxicity of three pesticides used in Costa Rican banana plantations. The in vitro genotoxicity of imazalil and thiabendazole fungicides and the insecticide chlorpyrifos, compounds used in Costa Rican banana plantations, was evaluated with the single-cell gel electrophoresis technique (comet assay.

Comparamos la privatización en Costa Rica y Chile, y en la discusión se sugiere que el modelo costarricense de privatización selectiva, limitada y concebida autóctonamente de Costa Rica lleva a un sistema de salud más solidario, equitativo, eficiente y satisfactorio para los usuarios que el modelo importado de privatización chileno.This study questions the premises that justify the neoliberal privatization of financing, managing and delivering health services. It also analyses the meaning of privatization and its strategies. We compare privatization in Chile and Costa Rica and suggest that the more limited, selective and locally designed privatization process in Costa Rica has resulted in a more equitable, and efficient health system than the imported privatization model introduced in Chile. The Costa Rican system also produces greater patient satisfaction and at the same time preserves the solidarity principle.

    2013-12-01

    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.

    Science.gov (United States)

    Morales-Ramírez, A

    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

    2010-11-01

    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.

    Full Text Available En este documento se elaboran y evalúan medidas alternativas de núcleo inflacionario para Costa Rica. La idea fundamental contempla al núcleo inflacionario como un indicador de la tendencia subyacente de la inflación capaz de capturar el componente del cambio total de precios común a todos los bienes y servicios, cuya persistencia se mantendría en el mediano y largo plazo y que excluye los cambios en los precios relativos de estos. 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. Por último, el ISI supera algunas de las limitaciones del INI, como son la falta de un criterio estadístico para definir el punto de corte de los bienes y servicios a excluir y el alto porcentaje del peso total del IPC eliminado. AbstractThis paper builds and evaluates several alternative measures of core inflation for Costa Rica. The chosen measure of core inflation is contrasted with the core inflation index (INI, which is the indicator of underlying inflation used today by the Central Bank of Costa Rica (BCCR.

    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.

    Full Text Available This paper presents the results of estimating three leading indicators for the turning points of the economic activity in Costa Rica. This was done following the methodology proposed by the Organization for Economic Cooperation and Development (OECD. The Monthly Economic Activity Index (IMAE in Spanish was selected as the reference variable.  A total of 270 data series were analyzed including monetary, real and job market variables, as well as price indices, external sector indicators and fiscal sector variables. The real sector information was disaggregated into three levels, which included the classification of data at an industrial level using the International Standard Industrial Classification (ISIC with two digits, information from the agricultural sector based on the Central Product Classification (CPC and information from the manufacturing sector.  A leading indicator was developed for each level of aggregation, resulting in average leads of 7 to 12 months compared to the reference variable.

    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.

    2011-01-01

    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.

  3. 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

    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 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 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 Macrobrachium amazonicum is the most frequently consumed freshwater crustacean by river communities of the Amazon. Despite its relative abundance and vast knowledge on the species from data on cultivated specimens, little is known regarding its biology in the natural environment, especially its use of creeks that are strongly influenced by the tide. Specimens of Macrobrachium amazonicum were collected in September 2006 (dry season and March 2007 (rainy season from two perennial creeks of the Guajará Bay in the state of Pará (northern Brazil, using traps similar to the matapis used by local fishermen to identify the spatial distribution of the species. Shrimps of all sizes use the tidal creeks in both seasons, including for breeding purposes. The greatest abundance of the species occurred in headwater areas and in the dry season. It is suggested that abundant allochthonous organic matter and the preference for protected areas may explain the abundance and breeding activity of this species in the headwaters of the creeks.Macrobrachium amazonicum é o crustáceo dulcícola mais frequentemente consumido pelas populações ribeirinhas da Amazônia.

    2011-12-01

    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.

  20. Familial Breast Cancer in Costa Rica: An Initial Approach

    2004-09-01

    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.

Para ello se tomaron diez árboles escogidos al azar, a los cuales se les evaluó la fenología, una vez al mes durante los dos primeros años y posteriormente cada dos meses. Además, se tomaron datos climatológicos in situ para establecer relaciones con el comportamiento fenológico. Se encontró que los árboles renuevan el follaje cada año, pero la caída ocurre durante el período lluvioso o a inicios del seco, por lo que, contrario a lo que sucede en otras especies nativas de este tipo de bosque, el déficit hídrico del suelo no es el responsable de la caída del follaje, sino que deben haber otros factores ambientales responsables de ello. Entre estos podrían estar el fotoperíodo y la presencia de herbívoros. Durante los meses más secos (marzo y abriltodos los árboles mantienen su follaje al máximo y para que esto ocurra deben existir también mecanismos fisiológicos particulares. Respecto a los procesos de floración y fructificación, estos se presentan todos los años, especialmente en el período de sequía, pero es posible que ocurran en cualquier otra época del año.

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

    2014-12-01

    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.

    Full Text Available We investigated the swimming abilities of three Costa Rican dry forest rodents (Coues’ rice rat, Oryzomys couesi, hispid cotton rat, Sigmodon hispidus, and spiny pocket mouse, Liomys salvini associated with a large marsh, Laguna Palo Verde, using 90 s swim trials in a plastic container. 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

    Full Text Available Partendo da una discussione critica delle ricerche che, negli ultimi vent’anni, hanno focalizzato i rapporti tra giovani, violenza e guerra nell’Africa sub-sahariana, l’articolo propone una prospettiva centrata sui processi di riproduzione sociale e sulle loro crisi. A tale scopo viene focalizzata e rielaborata la distinzione la tra la categoria antropologica dei “cadetti” – marcatamente relazionale e gerarchica – e la categoria dei “giovani” – che apre invece ad una definizione della gioventù come soggetto politico autonomo e si connette all’immaginario globale. Il conflitto recente in Costa d’Avorio viene dunque letto sulla base di questa distinzione contrastiva: si mostra come in esso dei “cadetti” (identificati nella figura dei ribelli che hanno lottato contro il presidente Gbagbo si siano opposti a dei “giovani” (identificati con i jeunes patriotes, ossia con i giovani nazionalisti che hanno sostenuto il presidente contro la ribellione. Queste forme differenti di soggettivazione politica vengono ricondotte alle crisi di riproduzione che hanno investito due parti diverse della società avoriana.

    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. Of the +100 freshwater species recorded in Central America, six are known only from Costa Rica, and one appears to be endemic to this country. 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). Both the Caribbean and Pacific species lists are growing. Additional collections of copepods at Cocos Island, an oceanic island 530 km away of the Pacific coast, have revealed many new records, including five new marine species from Costa Rica. Currently, the known diversity of marine copepods of Costa Rica is still in development and represents up to 52.6% of the total marine microcrustaceans recorded in the country. Future sampling and taxonomic efforts in the marine habitats should emphasize oceanic environments including deep waters but also littoral communities. Several Costa Rican records of freshwater copepods are likely to represent undescribed species. Also, the biogeographic relevance

La agricultura sostenible en Costa Rica debe reconocer la necesidad de intensificar la productividad como medio de soportar la acelerada demanda creada por el incremento poblacional, pero al mismo tiempo debe prever el mejor uso y conservación de los recursos naturales. Sin recursos naturales no hay agricultura y sin ésta no hay seguridad alimentaria. Es de esperar que Costa Rica pueda satisfacer la demanda creciente de alimentos y otros productos agrícolas; evitando el acelerado proceso de degradación que sufren nuestros suelos y bosques. El proceso de agricultura sostenible en Costa Rica y otros países de la región, presenta un incremento en la demanda de tierras y recursos naturales; lo cual suscita competencias y agudos conflictos sociales, económicos y ecológicos. Costa Rica debe plantearse una estrategia de desarrollo sostenible que contemple los efectos asociados del crecimiento demográfico, la seguridad alimentaria, la protección de la biodiversidad, la regeneración de los ecosistemas, el desarrollo de tecnologías amigables con el ambiente, la regulación sobre el acceso a los recursos naturales y la formación de capital humano

    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.

  5. Hydro and geothermal electricity as an alternative for industrial petroleum consumption in Costa Rica

    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.

  15. Anomalies in seasonal runoff patterns of Costa Rica

    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.

    Full Text Available Objective. Continuous Ambulatory Peritoneal Dialysis (CAPD is a kidney replacement therapy that has been recently incorporated in developing countries. 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. All positive animals except 1, and 9 negative animals (control group were examined by X-rays and electrocardiography, revealing different degrees of cardiomegaly and ECG alteration, consistent with Chagas disease pathology in one dog (SA-11 of the infected ones. 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.

  20. 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.

  1. 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.

  20. 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.

  1. 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.

  2. Erosión en la costa patagónica por cambio climático

    2004-12-01

    Full Text Available El área costera patagónica presenta evidencias de erosión en casi toda su extensión. Las causas de la erosión son consecuencia en mayor medida, del cambio climático ocurrido a partir del último período glaciario. La erosión se da primero por falta de acumulación directa (la carga de los ríos no llega a la línea de costa y segundo por el efecto de erosión inducida, ya que al no saturarse los flujos costeros por el aporte fluvial, estos lo hacen a expensas de la erosión de los afloramientos. Actualmente, en los principales ríos patagónicos no se dan las condiciones hidráulicas para el transporte de gravas. La falta de aporte por parte de los ríos actuales indica que las formas de acreción presentes en la faja litoral, constituidas por esa fracción clástica, corresponden a formas relícticas. La condición de formación de esos depósitos se daba en períodos en que los caudales imperantes estaban en relación con los tamaños de cauce. El nivel de base de los ríos del Pleistoceno, se halló en diversas oportunidades por debajo del nivel actual, alcanzando unos 150 m por debajo del nivel presente. Por ello es común la presencia de líneas de costa sumergidas con sedimentos aportados por los ríos durante esos períodos. La presencia de cañones submarinos en continuidad con cauces de ríos actualmente efímeros o permanentes de baja capacidad erosiva, indica cambios en el nivel del mar asociados a cambios climáticos.

    Desde meados da década de 90 que se verificou um boom no licenciamento de explorações de petróleo na costa atlântica africana, com consequências comerciais e implicações políticas. Acentuou-se o interesse dos EUA na zona, por pressão das suas empresas e da própria vontade de reduzir a dependência do petróleo do Médio Oriente. Em 2002 foi constituído o African Oil Policy Initiative Group, cujas propostas se situam entre a declaração do Golfo da Guiné como área de interesse vital para os EUA e ...

  6. Costa Rica During the Global Recession: Fiscal Stimulus with Tight Monetary Policy

    OpenAIRE

    Jose Antonio Cordero

    2009-01-01

    This paper shows that, in spite of a reasonably sized fiscal stimulus package, Costa Rica’s economy continues on a downward path, partly because fiscal policy is being offset by a tightening of monetary policy. The paper notes that the International Monetary Fund has insisted that Costa Rica’s monetary policy remain tight due to worries over inflation targets and a perceived risk of a balance of payments crisis. However, the author notes that the IMF could help prevent a balance of payments c...

    For some years now, the Happy Planet Organization presents the so-called ‘Happy Planet Index’ (HPI), which is an index of measuring the trade-off between ecological footprint data and life quality (Happy Life Years, HLYE). Costa Rica emerges from these comparisons as the world’s ‘best practice nation’, using a minimum amount of natural resources to achieve a maximum of human happiness. So is Costa Rica the pathway for humanity? There are shortcomings in the formula, with which the index is ca...

    2016-06-01

    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
