    Microstructural characterization techniques, including EDX (Energy Dispersive X-ray Analysis) microanalyses, were used to investigate the slag inclusions in the microstructure of ferrous artifacts of the Royal Iron Factory of Sao Joao de Ipanema (first steel plant of Brazil, XIX century), the D. Pedro II Bridge (located in Bahia, assembled in XIX century and produced in Scotland) and the archaeological sites of Sao Miguel de Missoes (Rio Grande do Sul, Brazil, production site of iron artifacts, the XVIII century) and Afonso Sardinha (Sao Paulo, Brazil production site of iron artifacts, XVI century). The microanalyses results of the main micro constituents of the microstructure of the slag inclusions were investigated by hierarchical cluster analysis and the dendrogram with the microanalyses results of the wüstite phase (using as critical variables the contents of MnO, MgO, Al{sub 2}O{sub 3}, V{sub 2}O{sub 5} and TiO{sub 2}) allowed the identification of four clusters, which successfully represented the samples of the four investigated sites (Ipanema, Sardinha, Missoes and Bahia). Finally, the comparatively low volumetric fraction of slag inclusions in the samples of Ipanema (∼1%) suggested the existence of technological expertise at the iron making processing in the Royal Iron Factory of Sao Joao de Ipanema.

  9. DIA-datasnooping and identifiability

    Science.gov (United States)

    Zaminpardaz, S.; Teunissen, P. J. G.

    2018-04-01

    In this contribution, we present and analyze datasnooping in the context of the DIA method. As the DIA method for the detection, identification and adaptation of mismodelling errors is concerned with estimation and testing, it is the combination of both that needs to be considered. This combination is rigorously captured by the DIA estimator. We discuss and analyze the DIA-datasnooping decision probabilities and the construction of the corresponding partitioning of misclosure space. We also investigate the circumstances under which two or more hypotheses are nonseparable in the identification step. By means of a theorem on the equivalence between the nonseparability of hypotheses and the inestimability of parameters, we demonstrate that one can forget about adapting the parameter vector for hypotheses that are nonseparable. However, as this concerns the complete vector and not necessarily functions of it, we also show that parameter functions may exist for which adaptation is still possible. It is shown how this adaptation looks like and how it changes the structure of the DIA estimator. To demonstrate the performance of the various elements of DIA-datasnooping, we apply the theory to some selected examples. We analyze how geometry changes in the measurement setup affect the testing procedure, by studying their partitioning of misclosure space, the decision probabilities and the minimal detectable and identifiable biases. The difference between these two minimal biases is highlighted by showing the difference between their corresponding contributing factors. We also show that if two alternative hypotheses, say Hi and Hj , are nonseparable, the testing procedure may have different levels of sensitivity to Hi -biases compared to the same Hj -biases.

  13. New evidence of cenozoic tectonism in the southeastern region of Brazil: the Barra de Sao Joao graben in Cabo Frio platform

    International Nuclear Information System (INIS)

    Mohriak, W.U.

    1990-01-01

    The western portion of the Campos Basin is limited by a hinge line that limits the deposition of pre-Aptian sediments in the offshore region. The Cabo Frio arch corresponds to a platform with smaller relative subsidence, where Tertiary sediments are deposited directly on shallow basement rocks. A conspicuous asymmetric graben occurs in the offshore region between Buzios and Macae. This rhomb-graben measures 20 km by 40 km, with the longer axis trending NE. The geological and geophysical characteristics of the Barra de Sao Joao graben supports a genetic affiliation with the onshore Taubate, Resende and Volta Redonda basins, rather than with the Campos Basin. The latter basin was formed in the Neocomian by rupturing of the Pangea, while the radiometric age determination of ankaramitic lavas near Volta Redonda suggests that the onshore basins were formed during the Eocene or Early Oligocene. A better understanding of the crustal geometry and the postulation of geodynamic models for these sedimentary basins will result from the integration of the onshore geology with the subsurface data presented in this paper.

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.

    The mesothelioma is a neoplasia originated in the serous membranes that drape the cellomic cavities and there cover the visceras that they contain, whose development has related to the exhibition to the asbestos. The present study describes the characteristics of the cases of mesothelioma pleural diagnosed in 3 adults hospitals in Costa Rica. 29 cases of pleural mesothelioma were found between 1972 and 2002 after reviewing the pathology service archives of the 3 national general hospitals of the Costa Rican social security health system. The incidence rate in 2002 was 1 case per 2 million; there were 15 females and 14 males, with a mean age of 54 years. Twenty cases presented with pleural effusion being dyspnea, chest pain, cough, fever and weight loss the most frequent symptoms. The disease was detected in all the cases because of an abnormal chest X-ray. The method used to obtain tissue for histological diagnosis was thoracotomy for 15 cases, pleural biopsy in 8, thoracoscopy in 4 and autopsy in 2. The histological diagnosis in 16 cases was fibrous mesothelioma, 10 malignant and 6 benign, 11 were epithelial (all malignant) and 2 were malignant mixed mesothelioma. The treatment in all the benign cases was surgical resection and none recurred. Two of the malignant lesions were resected, 1 had an extrapleural pneumonectomy along with pericardial and diaphragmatic resection, but the survival was not better than the rest of the malignant cases, with an average survival rate for all of them of only 6 months. Chemotherapy and radiotherapy showed no additional benefit. (author) [es

    2002-01-01

    Dynamic Information Architecture System (DIAS) is a flexible, extensible, object-based framework for developing and maintaining complex multidisciplinary simulations of a wide variety of application contexts. The modeling domain of a specific DIAS-based simulation is determined by (1) software Entity (domain-specific) objects that represent the real-world entities that comprise the problem space (atmosphere, watershed, human), and (2) simulation models and other data processing applications that express the dynamic behaviors of the domain entities. In DIAS, models communicate only with Entity objects, never with each other. Each Entity object has a number of Parameter and Aspect (of behavior) objects associated with it. The Parameter objects contain the state properties of the Entity object. The Aspect objects represent the behaviors of the Entity object and how it interacts with other objects. DIAS extends the ''Object'' paradigm by abstraction of the object's dynamic behaviors, separating the ''WHAT'' from the ''HOW.'' DIAS object class definitions contain an abstract description of the various aspects of the object's behavior (the WHAT), but no implementation details (the HOW). Separate DIAS models/applications carry the implementation of object behaviors (the HOW). Any model deemed appropriate, including existing legacy-type models written in other languages, can drive entity object behavior. The DIAS design promotes plug-and-play of alternative models, with minimal recoding of existing applications. The DIAS Context Builder object builds a constructs or scenario for the simulation, based on developer specification and user inputs. Because DIAS is a discrete event simulation system, there is a Simulation Manager object with which all events are processed. Any class that registers to receive events must implement an event handler (method) to process the event during execution. Event handlers can schedule other events; create or remove Entities from the

Su efecto puede ser directo al disminuir el rendimiento o indirecto al infectar los tubérculos y causar agallas o protuberancias, que les confiere una apariencia verrugosa, que afecta su calidad y reduce su valor comercial. En Capellades y Llano Grande de Cartago, Costa Rica, fueron encontrados tubérculos de papa, de la variedad Floresta y del clon Bananito, con numerosas protuberancias en su superficie. De las protuberancias se extrajo hembras ovígeras de Meloidogyne spp. Estudios morfológicos (diseño perineal de las hembras y moleculares (PCR y PCRRFLP mostraron que las hembras extraídas de las protuberancias pertenecen a la especie M. incognita. Se recomienda estudiar las causas que promueven la infección de los tubérculos en ambas localidades, ya que cerca del 90% del área cultivada de papa en el país corresponde a la variedad Floresta. En adición, se debe prestar especial atención a las zonas semilleristas, ya que los tubérculos-semilla podrían servir como fuente de inóculo y contribuir a la diseminación del patógeno a otras áreas.

    Full Text Available Nowcasting and forecasting ionospheric products and services for the European region are regularly provided since August 2006 through the European Digital upper Atmosphere Server (DIAS, http://dias.space.noa.gr. Currently, DIAS ionospheric forecasts are based on the online implementation of two models: (i the solar wind driven autoregression model for ionospheric short-term forecast (SWIF, which combines historical and real-time ionospheric observations with solar-wind parameters obtained in real time at the L1 point from NASA ACE spacecraft, and (ii the geomagnetically correlated autoregression model (GCAM, which is a time series forecasting method driven by a synthetic geomagnetic index. In this paper we investigate the operational ability and the accuracy of both DIAS models carrying out a metrics-based evaluation of their performance under all possible conditions. The analysis was established on the systematic comparison between models’ predictions with actual observations obtained over almost one solar cycle (1998–2007 at four European ionospheric locations (Athens, Chilton, Juliusruh and Rome and on the comparison of the models’ performance against two simple prediction strategies, the median- and the persistence-based predictions during storm conditions. The results verify operational validity for both models and quantify their prediction accuracy under all possible conditions in support of operational applications but also of comparative studies in assessing or expanding the current ionospheric forecasting capabilities.

    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.

    The management system of electronic waste is a project organized and financed by the bilateral agreement Costa Rica - Holanda, it is integrated by governmental and non-governmental enterprises. It was divided in two phases, first performed in 2003 which provided a diagnosis on the management of electronic resources, based on the diagnosis a propose of strategy for recycling was made. The second phase is given in 2005 with the implementation and realization of the project including two pilots plans located one at the Instituto Tecnologico de Costa Rica and another in the community of Escazu, at the end some recommendations were given to strengthen the system. The electronic waste were divided in white line, gray and brown line; those with pollutants such as phosphorus, chromium, cadmium, barium, lead, beryllium, mercury are toxic and have different effects on human health. The project in Costa Rica has taken as examples several recycling plants in different countries, among them one installed in Belgica. As an outstanding figure of the diagnosis made it was determined that Costa Rica has no legal support regarding the handling of such materials. It has been accumulated in 2007 more than 24 260 tonnes and is growing rapidly year after year. Within the achieved progress in the implementation of the project are: the creation of a legal support, the organization of the compliance unit of the project, the valuation of environmental costs and the increase of enterprises offering the service of primary treatment [es

O conto em questão permite esse tipo de abordagem, pelo fato da escritora se valer do tempo narrativo como categoria central em sua história, apresentando evocações de cenas da infância, no período escolar, rememoradas pela protagonista. A alteração da ordem temporal (anacronia é, portanto, evidente nesta narrativa, tendo a organização discursiva subvertida por meio de recuos temporais (analepses, que contribuem para a motivação da história. Como método, o levantamento de referências temporais contribuiu tanto no entendimento da configuração da analepse no discurso narrativo de “Testemunha”, quanto em sua classificação no que concerne à tipologia narrativa: narração ulterior, em sua totalidade. Por se tratar de um conto contemporâneo, notam-se inversões da ordem dos acontecimentos, por vezes, sem dizer; sendo cabível, portanto, a análise do aspecto linguístico (expressões, indícios temporais para auxiliar nas identificações das variações temporais e, consequentemente, do movimento retrospectivo do conto de Lídia Jorge.

  11. DIA1R is an X-linked gene related to Deleted In Autism-1.

    Directory of Open Access Journals (Sweden)

    Azhari Aziz

    Full Text Available BACKGROUND: Autism spectrum disorders (ASDS are frequently occurring disorders diagnosed by deficits in three core functional areas: social skills, communication, and behaviours and/or interests. Mental retardation frequently accompanies the most severe forms of ASDs, while overall ASDs are more commonly diagnosed in males. Most ASDs have a genetic origin and one gene recently implicated in the etiology of autism is the Deleted-In-Autism-1 (DIA1 gene. METHODOLOGY/PRINCIPAL FINDINGS: Using a bioinformatics-based approach, we have identified a human gene closely related to DIA1, we term DIA1R (DIA1-Related. While DIA1 is autosomal (chromosome 3, position 3q24, DIA1R localizes to the X chromosome at position Xp11.3 and is known to escape X-inactivation. The gene products are of similar size, with DIA1 encoding 430, and DIA1R 433, residues. At the amino acid level, DIA1 and DIA1R are 62% similar overall (28% identical, and both encode signal peptides for targeting to the secretory pathway. Both genes are ubiquitously expressed, including in fetal and adult brain tissue. CONCLUSIONS/SIGNIFICANCE: Examination of published literature revealed point mutations in DIA1R are associated with X-linked mental retardation (XLMR and DIA1R deletion is associated with syndromes with ASD-like traits and/or XLMR. Together, these results support a model where the DIA1 and DIA1R gene products regulate molecular traffic through the cellular secretory pathway or affect the function of secreted factors, and functional deficits cause disorders with ASD-like symptoms and/or mental retardation.

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

    Full Text Available Resumo: O artigo problematiza o discurso de crise ambiental na atualidade. A partir de algumas ferramentas da análise do discurso foucaultiana, discute-se um dos enunciados que compõe o discurso aqui investigado: o “Terror e medo pela perda do Planeta”. O estudo toma como corpus discursivo a revista Veja, especialmente reportagens produzidas a partir de 2001, em que enunciações ocupadas por terror e medo se tornam evidentes na mídia em análise. Discussões acerca do medo em Zigmunt Bauman, biopoder/biopolítica em Michel Foucault e cultura a partir de estudiosos do campo da Educação Ambiental são tomados como aportes teóricos desse estudo. Nas reportagens em evidência, há um forte chamamento para riscos e perigos quanto à continuidade de vida na Terra atrelado ao convite para que participemos da grande campanha mundial. Pensarmos possibilidades de enfrentar medos líquidos modernos, produzindo outros modos de nos relacionarmos com o ambiente, é um dos desafios dessa pesquisa.

  1. Novel roles of formin mDia2 in lamellipodia and filopodia formation in motile cells.

    Directory of Open Access Journals (Sweden)

    Changsong Yang

    2007-11-01

    Full Text Available Actin polymerization-driven protrusion of the leading edge is a key element of cell motility. The important actin nucleators formins and the Arp2/3 complex are believed to have nonoverlapping functions in inducing actin filament bundles in filopodia and dendritic networks in lamellipodia, respectively. We tested this idea by investigating the role of mDia2 formin in leading-edge protrusion by loss-of-function and gain-of-function approaches. Unexpectedly, mDia2 depletion by short interfering RNA (siRNA severely inhibited lamellipodia. Structural analysis of the actin network in the few remaining lamellipodia suggested an mDia2 role in generation of long filaments. Consistently, constitutively active mDia2 (DeltaGBD-mDia2 induced accumulation of long actin filaments in lamellipodia and increased persistence of lamellipodial protrusion. Depletion of mDia2 also inhibited filopodia, whereas expression of DeltaGBD-mDia2 promoted their formation. Correlative light and electron microscopy showed that DeltaGBD-mDia2-induced filopodia were formed from lamellipodial network through gradual convergence of long lamellipodial filaments into bundles. Efficient filopodia induction required mDia2 targeting to the membrane, likely through a scaffolding protein Abi1. Furthermore, mDia2 and Abi1 interacted through the N-terminal regulatory sequences of mDia2 and the SH3-containing Abi1 sequences. We propose that mDia2 plays an important role in formation of lamellipodia by nucleating and/or protecting from capping lamellipodial actin filaments, which subsequently exhibit high tendency to converge into filopodia.

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.

    Costa Rica, a small country with the population of 4 million, and without military and hence no military expenditure, promotes the use of renewable sources like Hydro, Mini hydro, Wind, Geothermal and Sun, mainly for electricity generation. Almost 90% of the electricity is produced from these renewable sources. Through different policies and some incentives, etc., private generation is also encouraged and there are some decentralized systems like solar water heaters, swimming pool heaters, cookers, dryers and stills and also photo voltaic panels. The last ones are mostly for the population where there is no electric grid. Depending on the province, 91-99.5% of the population is electrified. Government also encourages the use of energy saving devices specially at domestic and industrial sector. In addition to provide these data, some of the solar energy systems are mentioned. [Author].

    2000-03-01

    Novel designs of integrated fluidic microchips allow separations, chemical reactions, and calibration-free analytical measurements to be performed directly in very small quantities of complex samples such as whole blood and contaminated environmental samples. This technology lends itself to applications such as clinical diagnostics, including tumor marker screening, and environmental sensing in remote locations. Lab-on-a-Chip based systems offer many *advantages over traditional analytical devices: They consume extremely low volumes of both samples and reagents. Each chip is inexpensive and small. The sampling-to-result time is extremely short. They perform all analytical functions, including sampling, sample pretreatment, separation, dilution, and mixing steps, chemical reactions, and detection in an integrated microfluidic circuit. Lab-on-a-Chip systems enable the design of small, portable, rugged, low-cost, easy to use, yet extremely versatile and capable diagnostic instruments. In addition, fluids flowing in microchannels exhibit unique characteristics ('microfluidics'), which allow the design of analytical devices and assay formats that would not function on a macroscale. Existing Lab-on-a-chip technologies work very well for highly predictable and homogeneous samples common in genetic testing and drug discovery processes. One of the biggest challenges for current Labs-on-a-chip, however, is to perform analysis in the presence of the complexity and heterogeneity of actual samples such as whole blood or contaminated environmental samples. Micronics has developed a variety of Lab-on-a-Chip assays that can overcome those shortcomings. We will now present various types of novel Lab- on-a-Chip-based immunoassays, including the so-called Diffusion Immunoassays (DIA) that are based on the competitive laminar diffusion of analyte molecules and tracer molecules into a region of the chip containing antibodies that target the analyte molecules.

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 The article analyzes the reform of Article 1 of the Political Constitution of Costa Rica to acknowledge the multicultural and pluriethnic character of the nation, in terms of its protagonists and timing of approval. On the one hand, it suggests a relationship between racial formation processes and a constitutional multicultural delay. On the other, it recognizes the challenges and strategies of Afro-Costa Rican women to reframe this reform in terms of social justice.

  1. Differential Toxicity of mDia Formin-Directed Functional Agonists and Antagonists in Developing Zebrafish

    2018-04-01

    Full Text Available The mammalian Diaphanous-related (mDia formins are cytoskeletal regulators that assemble and, in some cases, bundle filamentous actin (F-actin, as well as stabilize microtubules. The development of small molecule antagonists and agonists that interrogate mDia formin function has allowed us to investigate the roles of formins in disease states. A small molecule inhibitor of FH2 domain (SMIFH2 inhibits mDia-dependent actin dynamics and abrogates tumor cell migration and cell division in vitro and ex vivo tissue explants. mDia formin activation with small molecule intramimics IMM01/02 and mDia2-DAD peptides inhibited glioblastoma motility and invasion in vitro and ex vivo rat brain slices. However, SMIFH2, IMMs, and mDia2 DAD efficacy in vivo remains largely unexplored and potential toxicity across a range of developmental phenotypes has not been thoroughly characterized. In this study, we performed an in vivo screen of early life-stage toxicity in Danio rerio zebrafish embryos 2 days post-fertilization (dpf in response to SMIFH2, IMM01/02, and mDia2 DAD. SMIFH2 at concentrations ≥5–10 μM induced significant defects in developing zebrafish, including shorter body lengths, tail curvature and defective tail cellularity, craniofacial malformations, pericardial edema, absent and/or compromised vasculature function and flow, depressed heart rates and increased mortality. Conversely, IMM and mDia2 DAD peptides were minimally toxic at concentrations up to 10–20 and 50 μM, respectively. SMIFH2's therapeutic potential may therefore be limited by its substantial in vivo toxicity at functional concentrations. mDia formin agonism with IMMs and mDia2 DADs may therefore be a more effective and less toxic anti-invasive therapeutic approach.

    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.

    Tumor cells rely upon membrane pliancy to escape primary lesions and invade secondary metastatic sites. This process relies upon localized assembly and disassembly cycles of F-actin that support and underlie the plasma membrane. Dynamic actin generates both spear-like and bleb structures respectively characterizing mesenchymal and amoeboid motility programs utilized by metastatic cells in three-dimensional matrices. The molecular mechanism and physiological trigger(s) driving membrane plasticity are poorly understood. mDia formins are F-actin assembly factors directing membrane pliancy in motile cells. mDia2 is functionally coupled with its binding partner DIP, regulating cortical actin and inducing membrane blebbing in amoeboid cells. Here we show that mDia2 and DIP co-tether to nascent blebs and this linkage is required for bleb formation. DIP controls mesenchymal/amoeboid cell interconvertability, while CXCL12 induces assembly of mDia2:DIP complexes to bleb cortices in 3D matrices. These results demonstrate how DIP-directed mDia2-dependent F-actin dynamics regulate morphological plasticity in motile cancer cells. PMID:23024796

Foram utilizados 30 cães neonatos de ambos os sexos, sem raça definida, aos três, 10, 17, 24, 31, 38 e 45 dias de idade. A contagem de leucócitos totais aos 45 dias (11.639±3.574 foi significativamente maior que no terceiro dia de idade (8.740±1.812 (P<0,05; não houve diferença entre a contagem total de linfócitos aos 45 dias em relação ao terceiro dia de idade. Quanto às subpopulações de LT CD4+ e LT CD8+, os percentuais de LT CD4+, aos três dias de idade (24,9±16,8%, foram inferiores quando comparados à média entre o 10°, o 24° e o 31°dia (35,5%, e os de CD8+, ao terceiro dia, menores em relação às médias do 10° e do 31° dia de idade. Pode-se concluir que as subpopulações de LT CD4+ e CD8+ sofrem oscilações durante o desenvolvimento pós-natal, sendo estas crescentes em relação aos níveis obtidos aos três dias de idade. A relação CD4+:CD8+ mostrou superioridade para o primeiro tipo celular, sendo que a maior relação entre CD4+ e CD8+ ocorreu no terceiro dia de idade. Com base nos resultados obtidos neste estudo, notaram-se as diferenças semanais nas populações linfocitárias, o que demonstra a dinâmica dessas células durante o período neonatal.

  6. Perspective View with Landsat Overlay, Costa Rica

    2002-01-01

    This perspective view shows the Caribbean coastal plain of Costa Rica, with the Cordillera Central rising in the background and the Pacific Ocean in the distance. The prominent river in the center of the image is the Rio Sucio, which merges with the Rio Sarapiqui at the bottom of the image and eventually joins with Rio San Juan on the Nicaragua border.Like much of Central America, Costa Rica is generally cloud covered so very little satellite imagery is available. The ability of the Shuttle Radar Topography Mission (SRTM) instrument to penetrate clouds and make three-dimensional measurements will allow generation of the first complete high-resolution topographic map of the entire region. These data were used to generate the image.This three-dimensional perspective view was generated using elevation data from SRTM and an enhanced false-color Landsat 7 satellite image. Colors are from Landsat bands 5, 4, and 2 as red, green and blue, respectively. Topographic expression is exaggerated two times.Landsat has been providing visible and infrared views of the Earth since 1972. SRTM elevation data matches the 30-meter resolution of most Landsat images and will substantially help in analyses of the large and growing Landsat image archive. The Landsat 7 Thematic Mapper image used here was provided to the SRTM by the United States Geological Survey, Earth Resources Observation Systems (EROS) Data Center, Sioux Falls, S.D.Elevation data used in this image was acquired by the SRTM aboard the Space Shuttle Endeavour, launched on February 11, 2000. SRTM used the same radar instrument that comprised the Spaceborne Imaging Radar-C/X-Band Synthetic Aperture Radar (SIR-C/X-SAR) that flew twice on the Space Shuttle Endeavour in 1994. SRTM was designed to collect three-dimensional measurements of the Earth's surface. To collect the 3-D data, engineers added a 60-meter-long (200-foot) mast, installed additional C-band and X-band antennas, and improved tracking and navigation devices

Entre las especies de plantas que más se mencionan en la bibliografía consultada están Allium sativum, Annona reticulata, Azadirachta indica, Capsicum frutescens, Chenopodium Ambrosiodes, Gliricidia sepium, Quassia amara y Ryania speciosa. Se resalta el hecho de que hasta la fecha, tanto su uso artesanal como su desarrollo comercial son mínimos, en relación con el potencial existente en el país. Con excepción de dos productos, los pocos bioplaguicidas de origen vegetal que se comercializan son importados.

  9. Assessment of mammography in Costa Rica

    2005-01-01

    An evaluation of national mammographic equipment was conducted, due to the increasing incidence of breast cancer in Costa Rican women. From June 2002 to October 2003, 2 of the 3 global indicators of image quality were evaluated, (mean glandular dose and phantom image) in 26 mammography machines facilitated by radiologists in charge of the same. The mean glandular dose found was 1.75 ± 0.60 mGy with a range of 0.8 a 2.56. Regarding quality image, 73% of the evaluated equipment was able to see 4 or more fibers, 53% saw 3 or more groups of microcalcifications and 82% saw 3 or more mass groups. All mean glandular doses were below the international reference dose value of 3 mGy. However, the analysis of phantom images showed that only 54% of all the equipment had a total score (sum of mass groups, fibers and microcalcifications) superior or equal to 10, as expected. A correct diagnosis that could eventually save the patient's life is the main objective of a mammogram; the factors that are degrading the images must be found and it might be necessary to increase the doses to achieve this. This study demonstrates the urgent necessity to introduce permanent quality control programs that will provide excellent images with the lowest internationally recommended doses.(author) [es

  10. [Education, modernity, and fertility in Costa Rica].

    1980-01-01

    In an effort to identify the causal mechanisms involved in the relationship between education and fertility in Costa Rica, all married women who were interviewed in the National Fertility Survey were reinterviewed in 1977-78. Questions on modernity and attitudes toward family size were designed to measure the extent of their influence on fertility. Questions on modernity were grouped into 4 measures of mass communications/information, sex roles, husband's power, and "instrumental activism." The intercorrelation of the 4 measures was enough to justify their use as separate subscales but high enough to permit their combined use as a single measure of modernity. The correlation between the combined total and education was strong and positive at .68, while the correlation between education and the number of live births controlled for age was -.35. Results of a multiple regression analysis indicate that high levels of general information and exposure to mass media are responsible for the positive correlation between education and fertility. A variety of scales were developed to measure the extent to which predispositions toward family size, numerical preference, and desire for additional children were responsible for the relationship between general information and fertility. Modernity and education showed strong negative relationships to predisposition toward family size, moderate negative relationships to size preference, and almost no relationship to the desire for more children.

    Exhumed faults are rough, often exhibiting topographic corrugations oriented in the direction of slip; such features are fundamental to mechanical processes that drive earthquakes and fault evolution. However, our understanding of corrugation genesis remains limited due to a lack of in situ observations at depth, especially at subducting plate boundaries. Here we present three-dimensional seismic reflection data of the Costa Rica subduction zone that image a shallow megathrust fault characterized by corrugated, and chaotic and weakly corrugated topographies. The corrugated surfaces extend from near the trench to several kilometres down-dip, exhibit high reflection amplitudes (consistent with high fluid content/pressure) and trend 11–18° oblique to subduction, suggesting 15 to 25 mm yr−1 of trench-parallel slip partitioning across the plate boundary. The corrugations form along portions of the megathrust with greater cumulative slip and may act as fluid conduits. In contrast, weakly corrugated areas occur adjacent to active plate bending faults where the megathrust has migrated up-section, forming a nascent fault surface. The variations in megathrust roughness imaged here suggest that abandonment and then reestablishment of the megathrust up-section transiently increases fault roughness. Analogous corrugations may exist along significant portions of subduction megathrusts globally.

    2018-01-01

    Full Text Available Costa Rica followed different steps in order to organise and implement a waste of electrical and electronic equipment (WEEE management system. This paper summarises the challenges, successes, and limitations of its implementation. Two phases were needed to set up the system. The first phase created a baseline followed by the designing of a strategy. The second phase promoted a Decree for WEEE management that prohibits discarding WEEE together with household waste, as well as the creation of a National Executive Committee with representatives of importers, consumers, and government, which will establish the quotes and treatment fees, and so on. Another outcome was the development of a strategy for the implementation of WEEE management for the country, the promotion of population awareness about their responsibility for WEEE management, and an example set up for other Latin American countries. This paper draws conclusions from the regulation and notes the required consistency with the existing national waste legislation in order to reduce approval times. Additionally, the importance of the participation of stakeholders representing different electric and electronic equipment (EEE sectors with the purpose of obtaining consensus on agreements is highlighted.

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.

    Multi-cellular spheroids are enriched in ascites of epithelial ovarian cancer (OvCa) patients. They represent an invasive and chemoresistant cellular population fundamental to metastatic dissemination. The molecular mechanisms triggering single cell invasive egress from spheroids remain enigmatic. mDia formins are Rho GTPase effectors that are key regulators of F-actin cytoskeletal dynamics. We hypothesized that mDia2-driven F-actin dynamics promote single cell invasive transitions in clinically relevant three-dimensional (3D) OvCa spheroids. The current study is a dissection of the contribution of the F-actin assembly factor mDia2 formin in invasive transitions and using a clinically relevant ovarian cancer spheroid model. We show that RhoA-directed mDia2 activity is required for tight spheroid organization, and enrichment of mDia2 in the invasive cellular protrusions of collagen-embedded OVCA429 spheroids. Depleting mDia2 in ES-2 spheroids enhanced invasive dissemination of single amoeboid-shaped cells. This contrasts with spheroids treated with control siRNA, where a mesenchymal invasion program predominated. Inhibition of another RhoA effector, ROCK, had no impact on ES-2 spheroid formation but dramatically inhibited spheroid invasion through induction of a highly elongated morphology. Concurrent inhibition of ROCK and mDia2 blocked single cell invasion from ES-2 spheroids more effectively than inhibition of either protein alone, indicating that invasive egress of amoeboid cells from mDia2-depleted spheroids is ROCK-dependent. Our findings indicate that multiple GTPase effectors must be suppressed in order to fully block invasive egress from ovarian cancer spheroids. Furthermore, tightly regulated interplay between ROCK and mDia2 signaling pathways dictates the invasive capacities and the type of invasion program utilized by motile spheroid-derived ovarian cancer cells. As loss of the gene encoding mDia2, DRF3, has been linked to cancer progression and

Daarteenoor is die geskiedenis van Da Gama se vaart in ’n epiese gedig deur Luís Vaz de Camões opgeteken in sy Os Lusíadas (1572, of Die seuns van Portugal. Die vraag wat ek wil beantwoord, gaan oor die plek en belang wat die dramaturg in Dias (1952 aan temas heg wat teruggevoer kan word tot kanto 5 van Os Lusíadas (1572. Ek neem aan dat die twee tekste met mekaar vergelyk kan word op grond van die teenwoordigheid van die mitiese karakter Adamastor in albei. Soos in Os Lusíadas (1572 neem Adamastor in Dias (1952 die vorm aan van ’n storm. My gevolgtrekking is dat albei tekste, ondanks verskillende oorspronge, ’n allegoriese en ’n nasionale aard vertoon.

    Full Text Available Observa-se uma tendência de aumento das classes médias, qualquer que seja o critério de inclusão adotado. Com uma definição ampla de classes médias, aumenta sua heterogeneidade e o grupo vulnerável tende a perder sua importância. Inversamente, a escolha de uma definição estreita de classes médias limita seu caráter "saco de gatos". Alguns veem nessa expansão das classes médias uma oportunidade de redinamizar o crescimento. Outros consideram que a expansão das classes médias decorre do crescimento e que um círculo virtuoso poderia existir entre crescimento e classes médias. No quadro de uma globalização controlada, essas duas teses estão erradas: uma redistribuição da renda em favor das categorias mais pobres pode dinamizar o crescimento

    Full Text Available Resumo A precipitação é um fenômeno meteorológico importante na região Tropical, caracterizada por sua variabilidade espacial-temporal e eventos extremos associados. Assim, a informação prévia da ocorrência de um dia ser seco ou chuvoso é de extrema importância para diversas atividades humanas, em especial a agricultura. O objetivo desse trabalho foi analisar a ocorrência de dias secos e chuvosos na região de Rio Largo–Alagoas, por meio da Cadeia de Markov. Dados diários de precipitação entre 1973 e 2008 foram utilizados. Na definição de dias secos e chuvosos consideraram-se seis limites de precipitação e, aplicou-se a Cadeia de Markov, para identificar as probabilidades de ocorrências condicionais de dias secos e chuvosos. A região de estudo apresentou estações seca (setembro a março e chuvosa (abril a agosto melhor definidas, considerados valores limites de precipitação entre 0 e 2 mm. Maior ocorrência de dias secos e chuvosos ocorreu de novembro a dezembro (94% e junho a julho (84%, respectivamente. A Cadeia de Markov permitiu concluir que a transição entre dias secos e chuvosos é baixa ao longo do ano.

    Full Text Available Diagnóstico de la comercialización de alimentos balanceados para perros en Costa Rica. 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

  5. Maps of ultraviolet radiation in Costa Rica

    2009-01-01

    Ultraviolet radiation (UV) has contributed relatively little energy to the solar spectrum; but is important, because it is biologically active. The software Surfer 8 has created maps designed of the territory of Costa Rica to assess the maximum levels of solar UV radiation on a horizontal plane. The data were used in creating the maps, were predicted at local noon in eighty-three locations scattered across the country, with a spectral atmospheric model which is physically established. The model has used as input data: the date and time, the location identified by latitude, longitude and height of land above sea level, the value of the vertical column ozone, surface albedo and atmospheric turbidity parameters. The estimate differs by 3% of the measurements made in situ, which agrees with the experimental data. The model has used the data estimation of UV radiation, clear sky conditions, which is the condition where you get the maximum energy possible in each locality. This is of fundamental importance when assessing the adverse effects on human health, leads the maximum intensity in this important solar spectrum band. A larger increase of 23% has presented in the UV radiation with altitude obtaining the hills and mountains the highest rates and places located at sea level and the lowest cost, the indices. The annual variation analysis has revealed an increase greater than 27% from the month of lowest UV radiation (December) and the month of greatest UV radiation (April). The issue is of particular interest because of the increasing number of people moving at different times of the year, altitudes over 2000 m altitude, in activities relating to tourism and employment. These individuals are significant increases in levels of UV solar radiation under conditions of clear skies. (author) [es

    Full Text Available With 51 100km2 of terrestrial area and 589 000km² of national waters, Costa Rica is considered one of the countries with the greatest biodiversity. It has approximately 3.5% of the world marine species. In the last four decades, Costa Rica has done a considerable effort to create a representative system of Protected Areas (PA, mainly terrestrial. We present an assessment of the current situation of the Marine Protected Areas (MPA in Costa Rica, through an historical analysis, and an evaluation of their distribution, coverage and management categories. Costa Rica has 166 protected areas covering 50% of the coastline; of these 20 are MPAs, classified as National Parks (90.6%, National Wildlife Refuges (6.6%, Wetlands (1.5%, Biological Reserves (1%, and one Absolute Natural Reserve (0.3%. According to IUCN criteria, 93.7% correspond to category II, 5% to IV and 1.3% to I. The marine protected surface is 5 296.5km², corresponding to 17.5% of the territorial waters and 0.9% of the Exclusive Economic Zone. The median distance between MPAs is 22.4km in the Pacific and 32.9km along the Caribbean. The median size is close to 54km². The main threats to MPAs are the lack of coordination between governmental agencies, limited economic resources, restricted patrolling and control, poor watershed management, and rampant coastal alteration.

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 Dias and Da Gama, Van Wyk Louw and Camões (revisited. Although he was the first Portuguese explorer who rounded the southernmost cape of Africa, world history does not herald Bartholomew Dias as an important figure. His compatriot Vasco da Gama was the first mariner who reached the Orient by navigating around the Cape. Despite Dias’s relative historical unimportance, N.P. van Wyk Louw preferred to write a radio play about him and his journey around the South African coast. Luís Vaz de Camões, on the other hand, wrote an epic poem about da Gama’s journey, which he titled Os Lusíadas (1572, or The sons of Portugal. The question I set out to answer, relates to the position and importance that the playwright of Dias (1952 attaches to themes in Canto 5 of Os Lusíadas (1572. I assume that the two can be compared due to the presence of the mythical character Adamastor in both. As in Os Lusíadas (1572, Adamastor takes the form of a storm in Dias (1952. I conclude that, in spite of different origins, both texts are allegorical and national in character. The differences in origin inspired a revised reading of Dias (1952.

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.

    It has been said that scientists and experts usually use 80% of their research time for data management (DOE, 2002). Only 20% of research time is used for purely scientific activities. This ratio should be reversed by introducing computer science technology. To realize this goal, the Japanese government supported the development of a data system called "Data Integration and Analysis System (DIAS)," as one of the national key projects promoted by the Council for Science and Technology Policy (CSTP) from 2006 to 2010. A follow-up 5-year project is also ongoing. The essential aim for the DIAS was to create knowledge that would enable solutions to problems and generate socioeconomic benefits. DIAS mainly consists of four data components including data injection, management, integration, and interoperability. DIAS is now tackling a large increase in the diversity and volume of data from observing the Earth. Dictionaries have been developing an ontology system for technical and geographical terms, and a metadata design has been completed according to international standards. The volume of data stored has exponentially increased. Previously, almost all of the large-volume data came from satellites, but model outputs occupy the largest volume of our data storage nowadays. In collaboration with scientific and technological groups, DIAS can accelerate data archiving by including data loading, quality checking, metadata registration, and our system data-searching capability is being enriched. DIAS also enables us to perform integrated research and realize interdisciplinarity. Essentially, we are now working in the fields of climate, water resources, food, fisheries, and biodiversity by collaborating between different disciplines and trying to develop bases of contribution to Sustainable Development Goals (SDGs).

Aponta ainda para os problemas que podem ocorrer com a ocupação e uso das faixas de lavagem das ondas, que constituem áreas de risco. A maior parte do litoral do Estado do Rio de Janeiro é formada por costões, cuja inclinação é classificada neste trabalho entre 15° e 45°. Acima deste limite é considerado falésia. Existem ainda extensos depósitos de blocos produzindo situações antagônicas: muitos foram originados por eventos catastróficos, mas posteriormente passaram a promover certa proteção à costa, por formar barreiras que dissipam a energia das ondas. Em geral, os costões marinhos nas áreas expostas às ondas de tempestades possuem inclinação média de 30° e comprimento médio de 50m. A extensão aumenta à medida que a inclinação da encosta diminui porque as ondas alcançam áreas mais distantes. Nas áreas semi expostas e protegidas, os comprimentos diminuem. No Estado foram identificadas 13 regiões costeiras distintas, entretanto, da divisa Oeste até a Ilha da Marambaia são comuns depósitos de blocos; nos municípios do Rio de Janeiro e Niterói predominam costões marinhos; entre Arraial do Cabo e Búzios, prevalecem falésias cristalinas; e entre Rio das Ostras e Macaé, o perfil do tipo bancada é o mais comum.

    Full Text Available With 51 100km2 of terrestrial area and 589 000km² of national waters, Costa Rica is considered one of the countries with the greatest biodiversity. It has approximately 3.5% of the world marine species. In the last four decades, Costa Rica has done a considerable effort to create a representative system of Protected Areas (PA, mainly terrestrial. We present an assessment of the current situation of the Marine Protected Areas (MPA in Costa Rica, through an historical analysis, and an evaluation of their distribution, coverage and management categories. Costa Rica has 166 protected areas covering 50% of the coastline; of these 20 are MPAs, classified as National Parks (90.6%, National Wildlife Refuges (6.6%, Wetlands (1.5%, Biological Reserves (1%, and one Absolute Natural Reserve (0.3%. According to IUCN criteria, 93.7% correspond to category II, 5% to IV and 1.3% to I. The marine protected surface is 5 296.5km², corresponding to 17.5% of the territorial waters and 0.9% of the Exclusive Economic Zone. The median distance between MPAs is 22.4km in the Pacific and 32.9km along the Caribbean. The median size is close to 54km². The main threats to MPAs are the lack of coordination between governmental agencies, limited economic resources, restricted patrolling and control, poor watershed management, and rampant coastal alteration.Con 51 100km2 de área terrestre y 589 000km² de aguas jurisdiccionales, Costa Rica es considerado uno de los países con mayor biodiversidad.

    Full Text Available O surgimento das tecnologias digitais permitiu o desenvolvimento de meios de contato inéditos entre empresas e consumidores, as chamadas novas mídias. Capazes de reconfigurar indústrias como a fonográfica e a do cinema, as novas mídias têm também impacto considerável na indústria da publicidade. O subsídio cruzado entre anunciantes, veículos de massa e consumidores, consolidado ao longo do século XX, se vê fragilizado com a popularização de aparelhos como Digital Video Recorders (DVRs, tablets, consoles de videogames e telefones celulares, dispositivos que transferem aos consumidores o poder de regular sua exposição à publicidade. Nesse novo ambiente, mídias tradicionais e novas mídias competem pela preferência de consumidores e pela verba dos anunciantes. Apesar da necessidade dos anunciantes de aferir e rentabilizar campanhas publicitárias, verificou-se que o investimento em veículos tradicionais vem crescendo, enquanto a audiência entregue diminui. Num panorama de mudanças, no presente estudo procura-se identificar que fatores influenciam o processo de compra de mídias por parte dos anunciantes, observando a percepção deles sobre mídias emergentes e tradicionais, seus benefícios e desafios. Para tanto, foi realizada uma pesquisa exploratória, utilizando uma abordagem qualitativa. Entre junho e julho de 2009, foram realizadas entrevistas em profundidade com os profissionais responsáveis pelas campanhas publicitárias de 15 empresas anunciantes de grande porte, atuantes em diversas indústrias. Ao analisar os dados colhidos em campo à luz da literatura estudada sobre o tema, a pesquisa identificou três fatores com forte influência sobre a definição do mix de mídias dos entrevistados: o uso de métricas inadequadas às mídias emergentes, a dependência dos anunciantes com as agências de publicidade e os veículos de massa e os próprios processos internos dos anunciantes.

    Full Text Available Vivemos em um período de intensas transformações proporcionadas pelos avanços tecnológicos. Nesse cenário, surgem novas formas de comunicação: novas estruturas discursivo-textuais, novas formas de produção, de interação e veiculação. O processo de narrativas transmídia é um exemplo oriundo desse cenário. Caracterizam-se por narrativas expandidas por diferentes plataformas de mídias a fim de gerar colaboração, participação e interação do interlocutor. Levando em consideração a amplitude e abrangência das estratégias transmidiáticas, este artigo apresenta uma análise de uma narrativa transmídia do ponto de vista da sua produção, com o objetivo de identificar e caracterizar suas estratégias discursivo -textuais com base nos conceitos da área da comunicação, sobretudo por meio de estudos de Henry Jenkins (2009 sobre narrativas transmídia e da Linguística Textual, principalmente os estudos de Koch (2011 acerca dos fatores de textualidade, com destaque para o conceito de intertextualidade, base do processo de produção transmídia. Nossa investigação se justifica já que se propõe a realizar um estudo mais abrangente em relação às novas formas de produção textual que surgem na atualidade, pois grande parte das pesquisas se encontram no âmbito de análise de textos digitais, isto é, hipertextos, e uma narrativa transmídia compreende além de textos para plataformas de mídia digitais, textos para plataformas de mídia impressa, eletrônica, entre outras.

    Abstract An updated inventory of the Bromeliaceae for Costa Rica is presented including citations of representative specimens for each species. The family comprises 18 genera and 198 species in Costa Rica, 32 species being endemic to the country. Additional 36 species are endemic to Costa Rica and Panama. Only 4 of the 8 bromeliad subfamilies occur in Costa Rica, with a strong predominance of Tillandsioideae (7 genera/150 spp.; 75.7% of all bromeliad species in Costa Rica). 124 species (62.6%) grow exclusively epiphytic, additional 59 spp. (29.8%) are facultative epiphytes. The most diverse genus is Werauhia, with 59 species (29.8% of the Costa Rican bromeliad flora), followed by Tillandsia with 40 species (20.2%) and Guzmania with 28 spp. (8.6%). PMID:24399894

    Full Text Available Many kinases are still ‘orphans,’ which means knowledge about their substrates, and often also about the processes they regulate, is lacking. Here, DIA1/C3orf58, a member of a novel predicted kinase-like family, is shown to be present in the endoplasmic reticulum and to influence trafficking via the secretory pathway. Subsequently, DIA1 is subjected to phosphoproteomics analysis to cast light on its signalling pathways. A liquid chromatography–tandem mass spectrometry proteomic approach with phosphopeptide enrichment is applied to membrane fractions of DIA1-overexpressing and control HEK293T cells, and phosphosites dependent on the presence of DIA1 are elucidated. Most of these phosphosites belonged to CK2- and proline-directed kinase types. In parallel, the proteomics of proteins immunoprecipitated with DIA1 reported its probable interactors. This pilot study provides the basis for deeper studies of DIA1 signalling.

    Anti-Dia is a clinically significant red cell antibody known to cause hemolytic disease of the newborn. Here, we report on a case of mild hemolytic disease of the newborn caused by Dia antibody. The mother had three prior pregnancies with no history of blood transfusion. She delivered a preterm 35-week-old female newborn by cesarean section. The neonate developed anemia and mild icterus on postnatal day five with hemoglobin of 9500 mg/dL and total bilirubin of 10 mg/dL. The direct antiglobulin test on the neonate's red blood cells was positive. The maternal serum and an eluate from the infant RBCs were negative in routine antibody detection tests but were positive using commercially prepared Di(a+) red cells. The neonate was discharged home in stable condition following treatment with erythropoietin and phototherapy. When a newborn has a positive DAT in the absence of major blood group incompatibility or commonly detected RBC antibodies, an antibody to a low frequency antigen such as Dia must be considered. Further immunohematology tests are required to determine presence of the antibody and the clinician must be alerted to closely monitor the infant for signs of anemia and hemolysis. PMID:26682081

    The DIAS/CEOS Water Portal is a part of the DIAS (Data Integration and Analysis System, http://www.editoria.u-tokyo.ac.jp/projects/dias/?locale=en_US) systems for data distribution for users including, but not limited to, scientists, decision makers and officers like river administrators. One of the functions of this portal is to enable one-stop search and access variable water related data archived multiple data centers located all over the world. This portal itself does not store data. Instead, according to requests made by users on the web page, it retrieves data from distributed data centers on-the-fly and lets them download and see rendered images/plots. Our system mainly relies on the open source software GI-cat (http://essi-lab.eu/do/view/GIcat) and open standards such as OGC-CSW, Opensearch and OPeNDAP protocol to enable the above functions. Details on how it works will be introduced during the presentation. Although some data centers have unique meta data format and/or data search protocols, our portal's brokering function enables users to search across various data centers at one time. And this portal is also connected to other data brokering systems, including GEOSS DAB (Discovery and Access Broker). As a result, users can search over thousands of datasets, millions of files at one time. Users can access the DIAS/CEOS Water Portal system at http://waterportal.ceos.org/.

Cette hypothèse, qui semblerait a priori évidente, met l'accent sur le fait que la production de l'information, en situation de guerre, ne dépend pas exclusivement des intentions et du travail des professionnels de l'information. En effet, de nombreuses contraintes militaires et stratégiques entrent en contradiction avec les principes de "neutralité", d"impartialité", etc. défendus par les médias de masse et leurs professionnels.

    An assessment of mineral potential, in terms of types and numbers of deposits, approximate location and associated tonnage and grades, is a valuable input to a nation's economic planning and mineral policy development. This study provides a methodology for applying benefit-cost analysis to mineral resource assessment programs, both to determine the cost effectiveness of resource assessments and to ascertain future benefits to the nation. In a case study of Costa Rica, the benefit-cost ratio of a resource assessment program was computed to be a minimum of 4:1 ($10.6 million to $2.5 million), not including the economic benefits accuring from the creation of 800 mining sector and 1,200 support services jobs. The benefit-cost ratio would be considerably higher if presently proposed revisions of mineral policy were implemented and benefits could be defined for Costa Rica

    Dengue virus (DENV) (Flavivirus, Flaviviridae) is a reemerging arthropod-borne virus with a worldwide circulation, transmitted mainly by Aedes aegypti and Aedes albopictus mosquitoes. Since the first detection of its main transmitting vector in 1992 and the invasion of DENV-1 in 1993, Costa Rica has faced dengue outbreaks yearly. In 2007 and 2013, Costa Rica experienced two of the largest outbreaks in terms of total and severe cases. To provide genetic information about the etiologic agents producing these outbreaks, we conducted phylogenetic analysis of viruses isolated from human samples. A total of 23 DENV-1 and DENV-2 sequences were characterized. These analyses signaled that DENV-1 genotype V and DENV-2 American/Asian genotype were circulating in those outbreaks. Our results suggest that the 2007 and 2013 outbreak viral strains of DENV-1 and DENV-2 originated from nearby countries and underwent in situ microevolution. © The American Society of Tropical Medicine and Hygiene.

    Full Text Available Understanding key aspects of the biology and ecology of chondrichthyan fishes (sharks, rays, and chimeras, as well as the range of threats affecting their populations is crucial given the rapid rate at which some species are declining. In the Eastern Tropical Pacific (ETP, the lack of knowledge, unreliable (or non-existent landing statistics, and limited enforcement of existing fisheries regulations has hindered management and conservation efforts for chondrichthyan species. This review evaluated our current understanding of Costa Rican chondrichthyans and their conservation status. Specifically, we (1 provide an updated checklist on the species richness, habitat use, and distribution patterns, (2 summarize the most relevant chondrichthyan studies (scientific publications, theses, and official technical reports, (3 identify knowledge gaps, (4 discuss fisheries-related threats, and (5 highlight the management challenges and research needs to effectively protect their populations. A total of 99 chondrichthyan species are formally recorded in Costa Rican waters, from which 15% are threatened with extinction and 41% are “Data Deficient” based on the IUCN (International Union for Conservation of Nature Red List. A total of 121 studies were published between 1891 and 2017; 82% in the Pacific (24% from Isla del Coco and only 18% from the Caribbean Sea. These results highlight the need to redirect research efforts on specific taxonomic groups and geographic regions (i.e., Caribbean. Based on our review, improving the quality and quantity of fisheries landing statistics, as well as determining the degree of overlap between chondrichthyans and Costa Rican fisheries remains a priority. We proposed an adaptive management framework for chondrichthyan fisheries in data-poor countries where management goals/targets are clearly defined. This framework could strengthen the conservation of chondrichthyan populations in Costa Rica and the region.

    Cost Rica's contraceptive social marketing project is scheduled to be launched in March 1985. The project is run through a for-profit corporation, Asdecosta, which is owned by the Costa Rican International Planned Parenthood affiliate. Asdecosta was formed as a for-profit entity because Costa Rican law prohibits product sales by nonprofit groups. The US Agency for International Development (AID) will allocate US$1.2 million over a 5-year period, 1983-88. The project manager, Jorge Lopez, is an economist with considerable experience in marketing. The project has lined up a top national distributor, a packaging company, and an advertising agency for its 1st product, a condom manufactured in the US by Ansell. Asdecost's target market is projected to include 50,000-75,000 couples at its peak operating capacity. An estimated 65% of Costa Rican women have used a contraceptive method at some time. The condom, pill, and IUD are the most popular methods. Eventually, Asdecosta expects to expand its product line to include oral contraceptives. Another goal is to counter the high drop out rate among users of government and other family planning services.

    Several highly infectious diseases can be transmitted through feces and cause elevated mortality among carnivore species. One such infectious agent, canine distemper virus (CDV; Paramyxoviridae: Morbillivirus), has been reported to affect wild carnivores, among them several felid species. We screened free-ranging and captive wild carnivores in Costa Rica for CDV. Between 2006 and 2012, we collected 306 fecal samples from 70 jaguars (Panther onca), 71 ocelots ( Leopardus pardalis ), five jaguarundis (Puma yaguaroundi), 105 pumas ( Puma concolor ), five margays ( Leopardus wiedii ), 23 coyotes ( Canis latrans ), and 27 undetermined Leopardus spp. We found CDV in six individuals: one captive jaguarundi (rescued in 2009), three free-ranging ocelots (samples collected in 2012), and two free-ranging pumas (samples collected in 2007). Phylogenetic analyses were performed using sequences of the phosphoprotein (P) gene. We provide evidence of CDV in wild carnivores in Costa Rica and sequence data from a Costa Rican CDV isolate, adding to the very few sequence data available for CDV isolates from wild Central American carnivores.

    2007-10-01

    Here we report a severe case of hemolytic anemia of the newborn with kernicterus caused by anti-Di(a) antibody. A full term male infant was transferred due to hyperbilirubinemia on the third day of life. Despite single phototherapy, the baby's total bilirubin had elevated to 30.1 mg/dL. After exchange transfusion, total bilirubin decreased to 11.45 mg/dL. The direct antiglobulin test on the infant's red cells was positive. The maternal and infant's sera showed a negative reaction in routine antibody detection tests, but were positive in Di(a) panel cells. The frequency of the Di(a) antigen among the Korean population is estimated to be 6.4-14.5%. Anti-Di(a) antibody could cause a hemolytic reaction against transfusion or hemolytic disease of the newborn. We suggest the need for reagent red blood cell panels to include Di(a) antigen positive cells in antibody identification test for Korean.

    The DIAS/CEOS Water Portal is a one of the DIAS (Data Integration and Analysis System, http://www.editoria.u-tokyo.ac.jp/projects/dias/?locale=en_US) systems for data distribution for users including, but not limited to, scientists, decision makers and officers like river administrators. This portal has two main functions; one is to search and access data and the other is to register and share use cases which use datasets provided via this portal. This presentation focuses on the first function, to search and access data. The Portal system is distributed in the sense that, while the portal system is located in Tokyo, the data is located in archive centers which are globally distributed. For example, some in-situ data is archived at the National Center for Atmospheric Research (NCAR) Earth Observing Laboratory in Boulder, Colorado, USA. The NWP station time series and global gridded model output data is archived at the Max Planck Institute for Meteorology (MPIM) in cooperation with the World Data Center for Climate in Hamburg, Germany. Part of satellite data is archived at DIAS storage at the University of Tokyo, Japan. This portal itself does not store data. Instead, according to requests made by users on the web page, it retrieves data from distributed data centers on-the-fly and lets them download and see rendered images/plots. Although some data centers have unique meta data format and/or data search protocols, our portal's brokering function enables users to search across various data centers at one time, like one-stop shopping. And this portal is also connected to other data brokering systems, including GEOSS DAB (Discovery and Access Broker). As a result, users can search over thousands of datasets, millions of files at one time. Our system mainly relies on the open source software GI-cat (http://essi-lab.eu/do/view/GIcat), Opensearch protocol and OPeNDAP protocol to enable the above functions. Details on how it works will be introduced during the

    Data independent acquisition (DIA) mass spectrometry is an emerging technique that offers more complete detection and quantification of peptides and proteins across multiple samples. DIA allows fragment-level quantification, which can be considered as repeated measurements of the abundance of the corresponding peptides and proteins in the downstream statistical analysis. However, few statistical approaches are available for aggregating these complex fragment-level data into peptide- or protein-level statistical summaries. In this work, we describe a software package, mapDIA, for statistical analysis of differential protein expression using DIA fragment-level intensities. The workflow consists of three major steps: intensity normalization, peptide/fragment selection, and statistical analysis. First, mapDIA offers normalization of fragment-level intensities by total intensity sums as well as a novel alternative normalization by local intensity sums in retention time space. Second, mapDIA removes outlier observations and selects peptides/fragments that preserve the major quantitative patterns across all samples for each protein. Last, using the selected fragments and peptides, mapDIA performs model-based statistical significance analysis of protein-level differential expression between specified groups of samples. Using a comprehensive set of simulation datasets, we show that mapDIA detects differentially expressed proteins with accurate control of the false discovery rates. We also describe the analysis procedure in detail using two recently published DIA datasets generated for 14-3-3β dynamic interaction network and prostate cancer glycoproteome. The software was written in C++ language and the source code is available for free through SourceForge website http://sourceforge.net/projects/mapdia/.This article is part of a Special Issue entitled: Computational Proteomics.

  6. Multiplexed data independent acquisition (MSX-DIA) applied by high resolution mass spectrometry improves quantification quality for the analysis of histone peptides.

    2016-08-01

    We present the MS-based application of the innovative, although scarcely exploited, multiplexed data-independent acquisition (MSX-DIA) for the analysis of histone PTMs. Histones are golden standard for complexity in MS based proteomics, due to their large number of combinatorial modifications, leading to isobaric peptides after proteolytic digestion. DIA has, thus, gained popularity for the purpose as it allows for MS/MS-based quantification without upfront assay development. In this work, we evaluated the performance of traditional DIA versus MSX-DIA in terms of MS/MS spectra quality, instrument scan rate and quantification precision using histones from HeLa cells. We used an MS/MS isolation window of 10 and 6 m/z for DIA and MSX-DIA, respectively. Four MS/MS scans were multiplexed for MSX-DIA. Despite MSX-DIA was programmed to perform two-fold more MS/MS events than traditional DIA, it acquired on average ∼5% more full MS scans, indicating even faster scan rate. Results highlighted an overall decrease of background ion signals using MSX-DIA, and we illustrated specific examples where peptides of different precursor masses were co-fragmented by DIA but not MSX-DIA. Taken together, MSX-DIA proved thus to be a more favorable method for histone analysis in data independent mode. © 2016 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

    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.

    2017-12-01

    Studies of intraseasonal and annual cycles of meteorological variables, using projections of climate change, are nowadays extremely important to improve regional socio-economic planning for countries. This is particularly true in Costa Rica, as Central America has been identified as a climate change hot spot. Today many of the economic activities in the region, especially those related to agriculture, tourism and hydroelectric power generation are linked to the seasonal cycle of precipitation. Changes in rainfall (mm/day) and in the diurnal temperature range (°C) for the periods 1950-2005 and 2006-2100 were investigated using the NASA Earth Exchange Global Daily Downscaled Projections (NEX-GDDP) constructed using the CMIP5 (Coupled Model Intercomparison Project version 5) data. Differences between the multi-model ensembles of the two prospective scenarios (RCP 4.5 and RCP 8.5) and the retrospective baseline scenario were computed. This study highlights Costa Rica as an inflexion point of the climate change in the region and also suggests future drying conditions.

    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.

    Enamel lesions in development were identified and classified in patients of Llano Grande de Cartago, examined at the Facultad de Odontologia of the Universidad de Costa Rica. A guide is provided over the topic. 15 children and 2 Costa Rican adults were selected. Clinical examinations, radiographs and clinical photographs were used as data collection method. Dental defects of the enamel were classified according to the possible genetic causes and without genetic causes. Imperfect Amelogenesis (IA) was diagnosed in 10 of patients. Hypoplastic IA was determined in 3 siblings with autosomal recessive inheritance, for 16% of the total sample. Hypomineralized IA was identified in an adult and two of his sons, with autosomal dominant inheritance. The remaining 4 cases of IA have been sporadic. Lesions of dental fluorosis were determined in the Horowitz index in 4 individuals, from 2 unrelated families. Other defects unspecified of the enamel or hypoplasias were found in 3 individuals. Enamel lesions in development should be classified with precision, for the purpose to inform to patients affected about their condition, origin, prognosis and appropriate treatment. The basis are established to implement reliability in the construction of family genealogy, identification and classification of enamel lesions, as well as the probabilities of future generations to express the lesions in the enamel of temporary or permanent dentition [es

    The establishment of the first radioactivity levels of natural radiation was carried out during the period 1991 to 1994 in three different regions of Costa Rica. The radionuclides studied belong to different soil types related to each selected region. Utilizing low level counting techniques the specific activity of the natural radioactive chains 238 U daughters, 232 Th and the element 40 K were measured for a total of 120 samples during this period. The amount of 137 Cs, a fall out radionuclide, was also studied. The average national values in Bq.kg -1 measured for 238 U were 11.66 for 214 Bi, 34.42 for 226 Ra and 10.73 for 232 Pb, for 232 Th daughters were 4.08 for 208 Tl, 9.65 for 212 Bi and 7.62 for 228 Ac. The specific activity value for 40 K was 95.14 Bq.kg -1 and for 137 Cs was 2.38 Bq.kg -1 . It is found that Costa Rica is not highly natural radioactive country and that the values for 137 Cs are well below international reported values [es

    With the intention of establishing economic inequities, the article analyzes the variations of the Unnecessarily Premature and Sanitarily Avoidable Mortality (MIPSE) of each of the 81 cantons of Costa Rica during 2000-2005. It is important to identify those inequities, to establish policies and strategies trying to mitigate them. It applies the MIPSE classification proposed by members of the Information and Studies Service, of the Catalunya's Sanitary Resources Headquarter, Spain. By an Indicator of Socioeconomic Development (IDSE) of a University of Costa Rica economist's team, it organised each canton in groups of quintiles (I for the richest, V for the poorest), previous people standardization. We found as a major causes of mortality MIPSE in the country: Heart Isquemic Disease (19,55% MIPSE causes), Traffic Accidents with Motor Vehicles (11,60%), Brain Vascular Disease (6,95%), Perinatal (6,92%) and Suicide (5,14%). The VIH infection - AIDS mortality, the Best Cancer in Women, Uterus Cancer, Skin Cancer and Hepatic Disease Secondary to Alcohol Consumption, affects more the cantons with better financial conditions and the Prostate Benign Hyperplasia mortality, Mothers mortality related with Pregnancy, Childbirth or Puerperal Stage and the Abdominal Hernia mortality, affects more to those with worst economic level. Two MIPSE groups were identified with similar inequality: Leukaemia and Congenital Cardiovascular Disease.

    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.

    Brucellosis has been an endemic disease of cattle and humans in Costa Rica since the beginning of XX century. However, brucellosis in sheep, goats, pigs, water buffaloes, horses and cetaceans, has not been reported in the country. We have performed a brucellosis survey in these host mammal species, from 1999-2016. In addition, we have documented the number of human brucellosis reported cases, from 2003-2016. The brucellosis seroprevalence in goat and sheep herds was 0.98% and 0.7% respectively, with no Brucella isolation. Antibodies against Brucella were not detected in feral or domestic pigs. Likewise, brucellosis seroprevalence in horse and water buffalo farms was estimated in 6.5% and 21.7%, respectively, with no Brucella isolation. Six cetacean species showed positive reactions against Brucella antigens, and B. ceti was isolated in 70% (n = 29) of striped dolphins (Stenella coeruleoalba). A steady increase in the diagnosis of human brucellosis cases was observed. Taking into account the prevalence of brucellosis in the various host mammals of Costa Rica, different measures are recommended.

    Full Text Available O presente artigo tem como objetivo refletir sobre a utilização das novas tecnologias pedagógicas na sala de aula promovendo uma discussão sobre a real importância da aplicação da mesma para uma diversificação das atividades educativas, levando, por consequência a uma diversificação da ação pedagógica. Daí a necessidade da inovação na rotina escolar, pois os alunos desta última década são os chamados nativos digitais. Sendo importante também a reflexão dos professores para a elaboração de ''plano de mídias'', para a definição do plano de aula no uso das mídias digitais na instituição educacional. O professor que resolve modificar seus métodos de ensino, é uma pessoa que compreende o valor e a necessidade de constante inovação na escola. Pois cada vez mais dependemos das mídias digitais para nossas funções cotidianas, que já estão presentes em todas as áreas da nossa vida social. Claro que nem sempre as mesmas estão disponíveis à todos. Contudo o professor deve estimular os alunos a usarem canais diversos de informação e aprendizagem, além de escutá-lo, contribuindo assim para enriquecer seu próprio repertório de meios e melhor prepará-lo para aprender e aprender, formando e construindo assim, cidadãos questionadores, críticos e principalmente pensadores.

    Full Text Available Este artigo enfoca as oportunidades de vida e a orientação dos consumidores da classe média na China, além de examinar suas características e sua participação nas práticas de consumo. Os dados foram fornecidos pelo China General Social Survey 2003. Devido a disparidades econômicas significativas entre as regiões, este artigo volta sua atenção para a divisão entre migrantes e habitantes nativos em cidades metropolitanas, que apresentam mais posições de classe média e onde a cultura de consumo prospera mais. A minha pesquisa mostrou que as diferenças entre os migrantes metropolitanos e os nativos metropolitanos são irrelevantes quanto à conquista de status social e participação nas práticas de consumo. Pode-se inferir que os migrantes metropolitanos são motivados a alcançar uma classe social ou uma renda mais alta e que seus gostos e estilos de vida são influenciados pelas cidades metropolitanas após sua migração. Mesmo que a frugalidade continue sendo um aspecto característico da população urbana chinesa, a classe média, os jovens e os grupos de renda alta apresentam uma forte orientação para o prazer e conforto pessoal.

Para consecução do objetivo, foi conduzido um survey a gestores de pequenas e médias empresas do município de Patos de Minas, pelo qual foram avaliadas as dimensões de clientes e consumidores, fornecedores, mercado, eficiência e eficácia organizacional e eficiência interorganizacional e suas relações com a rivalidade competitiva. Para a análise, foi utilizada a modelagem de equações estruturais, pelo método de mínimos quadrados parciais (PLS, realizando-se a validação dos modelos de mensuração e estrutural e, posteriormente, a análise dos coeficientes de caminho. Os resultados apontaram relação positiva entre todas as dimensões estratégicas avaliadas, com elevada relação com as dimensões clientes e consumidores e eficiência e eficácia organizacional e leve relação com a dimensão mercado. Observa-se que os sistemas de ERP, em pequenas e médias empresas, contribuem para dimensões mais endógenas e próximas da organização do que exógenas, sustentando a tese de necessidade de maturidade das organizações para se alcançar benefícios estratégicos com o uso de tecnologias da informação.

    Full Text Available Para este artigo, foram analisadas trezentas matérias extraídas dos principais jornais da mídia impressa brasileira sobre o tema da clonagem, em um período de dezoito meses, a contar do anúncio de Dolly, feito em fevereiro de 1997. A análise do material teve dois grandes objetivos: mapear os constantes morais a que a possibilidade da clonagem de seres humanos esteve associada e identificar alguns dos pressupostos morais da pesquisa científica com animais não-humanos e que foram reproduzidos irrefletidamente pela mídia. Além do reconhecimento de que houve antes uma difusão irrefletida do medo da clonagem em seres humanos que mesmo um debate ético frente à questão, a conclusão a que os autores chegaram com este estudo foi que há um sério descompasso entre as reflexões bioéticas e a mídia brasileira.This article was based on an analysis of three hundred articles from mainstream Brazilian periodicals over a period of eighteen months, beginning with the announcement of the Dolly case in February 1997. There were two main objectives: to outline the moral constants in the press associated with the possibility of cloning human beings and to identify some of the moral assumptions concerning scientific research with non-human animals that were published carelessly by the media. The authors conclude that there was a haphazard spread of fear concerning the cloning of human beings rather than an ethical debate on the issue, and that there is a serious gap between bioethical reflections and the Brazilian media.

    Full Text Available O presente trabalho propõe uma análise de como a dualidade e tragédia são representadas na obra Ópera dos Mortos do escritor mineiro Autran Dourado. Assim como o patriarcalismo, a vida da personagem Rosalina apresenta-se em decadência, pois herdará da família a incumbência de conservar a memória de seus antepassados. Por isso, apresenta formas contraditórias de viver a vida e transitará entre o mundo real e o imaginário. A estrutura trágica subjaz toda narrativa, pois os personagens são condenados a um destino trágico que é anunciado na obra através de símbolos. Observa-se que a estética barroca e as inspirações baseadas nas tragédias serviram de cenário para composição do romance.

    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.

    Full Text Available El trabajo cuestiona los argumentos que justifican la privatización neoliberal de la financiación, gestión y prestación de servicios de salud, y analiza el significado y estrategias de privatización. 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.

    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.

    The organophosphorus and organochlorine agrochemical residues distribution in sediments of 3 rivers located in an ornamental plant production area were analyzed in Poas canton, Alajuela, Costa Rica. The study comprised 8 months in order to assure 3 seasonal episodes: dry, transitional, and rainy seasons. Sediments were taken in 10 sampling stations along the rivers and characterized by a determination of their organic matter and texture. In 7 out of 10 sampling stations pesticide residues were detected in at least 1 of 4 samplings, but quantified only in 4 stations. Agrochemical residues evaluated included 21 organophosphorus and organochlorine pesticides; however, we found residues of only 3 organochlorine pesticides, due their high persistence in the sediment. Residues corresponded to PCNB (80-800 μg.kg -1 ), Endosulfan-β (40-50 μg.kg -1 ), and Endosulfan-α (90 μg.kg -1 ). Chlorothalonil was detected in only one sample. (author) [es

    2014-11-01

    Full Text Available We assess the utility of mixed-frequency models to forecast the quarterly growth rate of Costa Rican real GDP: we estimate bridge and MiDaS models with several lag lengths using information of the IMAE and compute forecasts (horizons of 0-4 quarters which are compared between themselves, with those of ARIMA models and with those resulting from forecast combinations. Combining the most accurate forecasts is most useful when forecasting in real time, whereas MiDaS forecasts are the best-performing overall: as the forecasting horizon increases, their precisionis affected relatively little; their success rates in predicting the direction of changes in the growth rate are stable, and several forecastsremain unbiased. In particular, forecasts computed from simple MiDaS with 9 and 12 lags are unbiased at all horizons and information sets assessed, and show the highest number of significant differences in forecasting ability in comparison with all other models.

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.

    Fischer, Steven C.

    2005-01-01

    This note is a preliminary investigation into the relationship between the efficiency of electricity utilization in the Costa Rican industrial sector and the competitive pressures generated by the implementation of economic reforms, in particular, the progressive liberalization of international trade, in the years since the debt and economic crisis of the early 1980s. The steady, year-by-year, reduction in the rate of import tariff protection, with only temporary interruptions and reverses, has been the most consistently implemented component of the macroeconomic, trade, and financial sector reforms upon which this country has embarked over the past two decades. The note sheds some light on the nature of the general policy environment that is conductive to an efficient utilization of energy in the productive sectors and to the success of national energy efficiency promotion programs in this and other parts of the world.

    Treguear, T; Peters, L

    1995-01-01

    In San Jose, Costa Rica, the nongovernmental organization PROCAL has established two rescue homes for sexually abused girls 10-15 years of age. One of these homes is devoted to the care of pregnant girls. In almost all cases, the perpetrator was a male relative. Since girls are taught they must obey older male relatives, they are powerless to stop the abuse. When girls become pregnant as a result of sexual abuse, they face social ostracism and are blamed for their participation in sexual activity. PROCAL counsels the girls that they are victims of their own lack of power and provides them with skills and education they need to return to society and start a new life. The stories of two young girls who became pregnant as a result of sexual abuse and were helped by PROCAL are presented.

  12. Ecosystem-Level Carbon Stocks in Costa Rican Mangrove Forests

    2012-12-01

    Tropical mangroves provide a wide variety of ecosystem services, including atmospheric carbon sequestration. Because of their high rates of carbon accumulation, the large expected size of their total stocks (from 2 to 5 times greater than those of upland tropical forests), and the alarming rates at which they are being converted to other uses (releasing globally from 0.02 to 0.12 Pg C yr-1), mangroves are receiving increasing attention as additional tools to mitigate climate change. However, data on whole ecosystem-level carbon in tropical mangroves is limited. Here I present the first estimate of ecosystem level carbon stocks in mangrove forests of Central America. I established 28, 125 m-long, sampling transects along the 4 main rivers draining the Térraba-Sierpe National Wetland in the southern Pacific coast of Costa Rica. This area represents 39% of all remaining mangroves in the country (48300 ha). A circular nested plot was placed every 25 m along each transect. Carbon stocks of standing trees, regeneration, the herbaceous layer, litter, and downed wood were measured following internationally-developed methods compatible with IPCC "Good Practice Guidelines". In addition, total soil carbon stocks were determined down to 1 m depth. Together, these carbon estimates represent the ecosystem-carbon stocks of these forests. The average aboveground carbon stocks were 72.5 ± 3.2 MgC ha-1 (range: 9 - 241 MgC ha-1), consistent with results elsewhere in the world. Between 74 and 92% of the aboveground carbon is stored in trees ≥ 5cm dbh. I found a significant correlation between basal area of trees ≥ 5cm dbh and total aboveground carbon. Soil carbon stocks to 1 m depth ranged between 141 y 593 MgC ha-1. Ecosystem-level carbon stocks ranged from 391 MgC ha-1 to 438 MgC ha-1, with a slight increase from south to north locations. Soil carbon stocks represent an average 76% of total ecosystem carbon stocks, while trees represent only 20%. These Costa Rican mangroves

    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

    Full Text Available The coral reefs, seagrasses and mangroves from the Costa Rican Caribbean coast have been monitored since 1999 using the CARICOMP protocol. Live coral cover at Meager Shoal reef bank (7 to 10m depth at the Parque Nacional Cahuita (National Park, increased from 13.3% in 1999, to 28.2% in 2003, but decreased during the next 5 years to around 17.5%. Algal cover increased significantly since 2003 from 36.6% to 61.3% in 2008. The density of Diadema antillarum oscillated between 2 and 7ind/m2, while Echinometra viridis decreased significantly from 20 to 0.6ind/m2. Compared to other CARICOMP sites, live coral cover, fish diversity and density, and sea urchin density were low, and algal cover was intermediate. The seagrass site, also in the Parque Nacional Cahuita, is dominated by Thalassia testudinum and showed an intermediate productivity (2.7±1.15 g/m2/d and biomass (822.8±391.84 g/m2 compared to other CARICOMP sites. Coral reefs and seagrasses at the Parque Nacional Cahuita continue to be impacted by high sediment loads from terrestrial origin. The mangrove forest at Gandoca, within the Refugio Nacional de Vida Silvestre Gandoca-Manzanillo (National Wildlife Refuge, surrounds a lagoon and it is dominated by the red mangrove, Rhizophora mangle. Productivity and flower production peak was in July. Biomass (14kg/m2 and density (9.0±0.58 trees/100m2 in Gandoca were relatively low compared to other CARICOMP sites, while productivity in July in Costa Rica (4g/m2/d was intermediate, similar to most CARICOMP sites.

    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.

    The purpose of this paper is to compare four major exchange rate models for the Costa Rica Colon. We examine exchange rate data for the Costa Rica/U.S. dollar relationship from 1981-2007 and find that monetary models have a higher explanatory ability whereas the Mundell-Fleming model performs better in forecasting exchange rates than other models. The coefficient of the interest rate differential in the uncovered interest parity model has a wrong sign.

    Morphological plasticity in response to environmental cues in migrating cancer cells requires F-actin cytoskeletal rearrangements. Conserved formin family proteins play critical roles in cell shape, tumor cell motility, invasion and metastasis, in part, through assembly of non-branched actin filaments. Diaphanous-related formin-2 (mDia2/Diaph3/Drf3/Dia) regulates mesenchymal-to-amoeboid morphological conversions and non-apoptotic blebbing in tumor cells by interacting with its inhibitor diaphanous-interacting protein (DIP), and disrupting cortical F-actin assembly and bundling. F-actin disruption is initiated by a CXCL12-dependent mechanism. Downstream CXCL12 signaling partners inducing mDia2-dependent amoeboid conversions remain enigmatic. We found in MDA-MB-231 tumor cells CXCL12 induces DIP and mDia2 interaction in blebs, and engages its receptor CXCR4 to induce RhoA-dependent blebbing. mDia2 and CXCR4 associate in blebs upon CXCL12 stimulation. Both CXCR4 and RhoA are required for CXCL12-induced blebbing. Neither CXCR7 nor other Rho GTPases that activate mDia2 are required for CXCL12-induced blebbing. The Rho Guanine Nucleotide Exchange Factor (GEF) Net1 is required for CXCL12-driven RhoA activation and subsequent blebbing. These results reveal CXCL12 signaling, through CXCR4, directs a Net1/RhoA/mDia-dependent signaling hub to drive cytoskeleton rearrangements to regulate morphological plasticity in tumor cells. These signaling hubs may be conserved during normal and cancer cells responding to chemotactic cues. Copyright © 2017 Elsevier Inc. All rights reserved.

    Full Text Available O objetivo deste artigo é descrever a rotina de adolescentes de baixa renda que cuidam de seus irmãos. Participaram do estudo 20 adolescentes de 12 a 16 anos. Foi utilizada uma ficha de dados sociodemográficos, genograma familiar e entrevista semiestruturada sobre um dia de suas vidas. Organizaram-se as atividades relatadas em cinco categorias: cuidado pessoal, cuidado dos irmãos, domésticas, escolares e de lazer. A partir dessas atividades dividiram-se os participantes em três grupos: responsáveis pelo cuidado dos irmãos, ajudam suas mães e sem essas atividades. Os resultados indicaram que adolescentes de ambos os sexos cuidam dos irmãos, mas são as meninas que mais assumem tarefas domésticas. Quando responsabilizados pelo cuidado, suas atividades escolares e de lazer são prejudicadas.

    2008-11-01

    Full Text Available Se é verdade que toda arte é feita com os meios de seu tempo, a artemí­dia representa a expressão mais avançada da criação artí­stica atual. Hoje, cada vez mais, os artistas lançam mão de câmeras, computadores, sintetizadores para construir suas imagens, suas músicas, seus textos, seus ambientes. De repente, nos damos conta de uma multiplicação vertiginosa de trabalhos realizados com pesada mediação tecnológica. Naturalmente, as técnicas, os artifí­cios, os dispositivos de que se utiliza o artista para conceber, construir e exibir seus trabalhos não são apenas ferramentas inertes, nem mediações inocentes, indiferentes aos resultados, que se poderiam substituir por quaisquer outras. Eles estão carregados de conceitos, eles têm uma história, eles derivam de condições produtivas bem determinadas. A artemí­dia, como qualquer arte fortemente determinada pela mediação técnica, coloca o artista diante do desafio permanente de se contrapor ao determinismo tecnológico, de recusar o projeto industrial já embutido nas máquinas e aparelhos, evitando assim que sua obra resulte simplesmente num endosso dos objetivos de produtividade da sociedade tecnológica. Ela traça uma diferença ní­tida entre o que é, de um lado, a mera produção industrial de desenhos agradáveis para as mí­dias de massa e, de outro, a busca de uma ética e uma estética para a era eletrônica. Palavras-chave artemí­dia, meios de comunicação de massa, mediação tecnológica Abstract When we consider that the art of every era is made using the media available at that time, it follows that the media arts represent the most advanced expression of current artistic creation. Today, more than ever, artists are using cameras, computers, synthesizers to construct their images, their music, their texts, their environments.

    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.

    Automation of dietary assessment can reduce limitations of established methodologies, by alleviating participant and researcher burden. Designed as a research tool, the electronic Dietary Intake Assessment (e-DIA) is a food record in mobile phone application format. The present study aimed to examine the relative validity of the e-DIA with the 24-h recall method to estimate intake of food groups. A sample of eighty university students aged 19-24 years recorded 5 d of e-DIA and 3 d of recall within this 5-d period. The three matching days of dietary data were used for analysis. Food intake data were disaggregated and apportioned to one of eight food groups. Median intakes of food groups were similar between the methods, and strong correlations were found (mean: 0·79, range: 0·69-0·88). Cross-classification by tertiles produced a high level of exact agreement (mean: 71 %, range: 65-75 %), and weighted κ values were moderate to good (range: 0·54-0·71). Although mean differences (e-DIA-recall) were small (range: -13 to 23 g), limits of agreement (LOA) were relatively large (e.g. for vegetables, mean difference: -4 g, LOA: -159 to 151 g). The Bland-Altman plots showed robust agreement, with minimum bias. This analysis supports the use of e-DIA as an alternative to the repeated 24-h recall method for ranking individuals' food group intake.

    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.

    2011-01-01

    Electron microscopy has celebrated in 2009 the XXXV anniversary in Costa Rica. The history of the electron microscopy was initiated with the donation of a microscope by Japan and the establishment of the Unidad de Microscopia Electronica (UME), which later, has been consolidated as the Centro de Investigacion en Estructuras Microscopicas (CIEMic) of the Universidad de Costa Rica (UCR). This center has realized its own research and has gave support to different units of the UCR, state universities and the private sector. Currently, the CIEMic has had two transmission electron microscopes (TEM) and two scanning electron microscopes (SEM), besides of optical microscopy equipment, including a laser confocal microscope. The two fundamental types of electron microscopes (TEM and SEM) have generated different images. While the first has had a resolution that has allowed to analyze virus, usually their images have been flat; however, with some special techniques can obtain three-dimensional images. The image in the TEM is generated by electrons that have passed through the sample, and to interact with its atoms have changed its energy and trajectory. This, at the end, has impacted on a photosensitive screen that has become in flashes, whose intensity has depended on its energy and form the image. Meanwhile, in the MER, the image has been normal type, although with less resolution. The electrons in the MER are focused on a small area of the sample in which have interacted with the atoms of this, and has generated a a series of signals, including the most used were the secondary electrons and characteristic X-rays. In both cases, an electron from beam has generated in the filament a collision against an electron of the sample and has given part of its energy to the degree of release of its atom and issued out of the sample; this has been called secondary electrons. X-rays have been generated when an electron of the same atom that has lost the secondary electron, but in an

    This perspective view shows the northern coastal plain of Costa Rica with the Cordillera Central, composed of a number of active and dormant volcanoes, rising in the background. This view looks toward the south over the Rio San Juan, which marks the boundary between Costa Rica and Nicaragua. The smaller river joining Rio San Juan in the center of the image is Rio Sarapiqui, which is navigable upstream as far inland as Puerto Viejo (Old Port) de Sarapiqui at the mountain's base. This river was an important transportation route for those few hardy settlers who first moved into this region, although as recently as 1953 a mere three thatched-roof houses were all that comprised the village of Puerto Viejo.This coastal plain is a sedimentary basin formed about 50 million years ago composed of river alluvium and lahar (mud and ash flow) deposits from the volcanoes of the Cordillera Central. It comprises the province of Heredia (the smallest of Costa Rica's seven) and demonstrates a wide range of climatic conditions, from warm and humid lowlands to cool and damp highlands, and including the mild but seasonally wet and dry Central Valley.This image was generated in support of the Central American Commission for Environment and Development through an agreement with NASA. The Commission involves eight nations working to develop the Mesoamerican Biological Corridor, an effort to study and preserve some of the most biologically diverse regions of the planet.This three-dimensional perspective view was generated using topographic data from the Shuttle Radar Topography Mission (SRTM) and an enhanced false-color Landsat 7 satellite image. Colors are from Landsat bands 5, 4, and 2 as red, green and blue, respectively. Topographic expression is exaggerated 2X.Landsat has been providing visible and infrared views of the Earth since 1972. SRTM elevation data matches the 30-meter resolution of most Landsat images and will substantially help in analyses of the large and growing Landsat

    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

    Propolis is produced by Apis mellifera bees from resins of plants that are found around the apiary. The chemical composition is highly variable and Costa Rica has reported without studies of characterization to define the types of propolis in the country. 119 samples were collected from beekeeping areas of the country. The spectrum of 1 H-NMR and its antioxidant activity against DPPH radical were measured. The spectra have been divided into 243 blocks of 0,04 ppm and processed with the Minitab software for multivariate analysis. 99 of the samples collected were used for construction of models for the valuation of the predictive ability of the model have been used coefficients of determination (R 2 ) of prediction by the software and the remaining 20 samples. The existence of three types of propolis with chemically different metabolomes were determined by principal component analysis (PCA). A prediction model was constructed by analysis of partial least squares (PLS). The prediction model has allowed to classify a propolis according to the level of antioxidant activity (AAO), high (type I and II) or low (type III) from the spectrum of 1 H-NMR. The R 2 has been 0.88 and R 2 prediction of 0, 718 for new samples. The nconiferyl benzoate of group I and nemorosone of the group II as two discriminated antioxidants among the groups I and II were isolated and high concentration levels of these compounds have been differentiated with respect to type III. This has allowed the construction of a linear discriminant model with a success rate of 100% for the samples used for formulation and 92,9 for the prediction of different samples. The classification systems could be applied to the standardization of the quality of propolis from Costa Rica for future medicinal or cosmetic applications that take advantage of its antioxidant properties. Also, the methylated derivative has isolated and identified of the nconiferyl benzoate thereof propolis than was obtained his counterpart

    A geologic map scale 1:50 000, stratigraphic and structural of the 509 km 2 of the Tapanti quadrangle is presented. The Tapanti quadrant is located in the central region of Costa Rica and belongs to the Central Costa Rica Deformed Belt (CCRDB). The CCRDB was a consequence of the interaction of the Cocos Ridge and the Western edge of the Panama microplate. Petrographic, geochemistry and paleontological analyzes were performed by selecting samples collected in the more than 100 field visits, with more than 300 outcrops raised. The geological information was compiled in a Geographical Information System. Lambert North coordinate system was employed. Aerial and topographic photographs from the TERRA Project 1997 and Digital Elevation Model were used. 18 rock samples were analyzed petrographically to discard altered samples. Rock samples were screened. The gravels or grains obtained were washed with deionized water in an ultrasonic stack. Gravel with signs of alteration were discarded by stereoscopic microscope. The powder obtained from the spraying of 25 mg of gravel each sample was melted and combined with Lithium tetraborate (Li2B4O7) and poured into glass discs. The discs were analyzed to determine concentrations of major elements and traced through of X-Ray Fluorescence in a Bruker S4 Pioner, and by a mass spectrometer (LA-ICP-MS) in a Micromass Platform ICP-MS, respectively. The oldest rocks mapped in this work are Miocene in age and they belongs to Pacacua, Pena Negra and Coris formations, than form the western edge of the Candelaria basin. Three igneous events were distinguished. First, the Miocene volcanic arc, which is represented by the rocks of La Cruz Formation and the clasts of Pacacua Formation. Another period of igneous activity was recorded in Grifo Alto and Doan formations and the Tapanti Intrusive, with an age range of 0.6-0.03 Ma. From a geochemical point of view a change in the composition of magmatism was remarkable between 10 to 6 Ma, expressed

    Full Text Available Focalizando as tragédias sofocleanas Rei Édipo e Édipo em Colono, mas considerando também outras versões e documentos iconográficos relativos ao mito de Édipo, busca-se evidenciar que a noção do apotropaico desempenha, nesse contexto, um papel significativo. Sugere-se que as crenças e as práticas nas quais este valor se exprime têm raízes no plano mais profundo de uma cosmovisão tradicional dos helenos: têm a ver com idéias sobre o destino e com categorias fundamentais do pensamento religioso dos gregos. Sustenta-se que o código do apotropaico tem na magia (domínio ao qual inúmeros estudos tendem a cingi-lo, apenas uma de suas expressões, cuja interpretação depende da análise de outros discursos da cultura grega. Na encenação da história de Édipo, a tragédia evidencia com singular clareza o sentido mais profundo do apotropaico.Focusing mainly on the Sophoclean tragedies Oedipus Rex and Oedipus at Colonnus, but also considering other versions of the Oedipus myth and some of the iconographic documents relating to it, this article looks to show that the apotropaic element plays an important role in this mythic context. It suggests that the beliefs and practices through which the apotropaic value is expressed are rooted in the deepest grounds of the Greek Weltanschauung and related to conceptions of fate and the basic categories of Greek religious thought. Although many studies usually restrict its operation to this circle, the article argues that magic is just one of the fields in which the apotropaic code is expressed, and that the interpretation of this code requires the consideration of other discourses and the analysis of other aspects of Greek culture. In theatrical presentations of the Oedipus tale, the tragedy reveals the deepest meaning of the apotropaic with singular clarity.

    2016-06-01

    Leaf Area Index (LAI) has been defined as the total leaf area (one-sided) in relation to the ground. LAI has an impact on tree growth and recruitment through the interception of light, which in turn affects primary productivity. Even though many instruments exist for estimating LAI from ground, they are often laborious and costly to run continuously. Measurements of LAI from the field using traditional sensors (e.g., LAI-2000) require multiple visits to the field under very specific sky conditions, making them unsuitable to operate in inaccessible areas and forests with dense vegetation, as well as areas where persistent sunny conditions are the norm like tropical dry forests. With this context, we proposed a methodology to characterize light diffusion based on NDVI and LAI measurements taken from the field in two successional stages in the tropical dry forest of Santa Rosa National Park in Costa Rica. We estimate a "K" coefficient to characterize light diffusion by the canopy, based on field NDVI measurements derived from optical phenology instruments and MODIS NDVI. From the coefficients determined, we estimated LAI values and compared them with ground measurements of LAI. In both successional stages ground measurements of LAI had no significant difference to the tower-derived LAI and the estimated LAI from MODIS NDVI.

    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 Moin 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 μg / g, respectively) and lower in Moin Bay (3.4% and 52 μg / g, respectively). Zinc mean concentration was also higher in Golfito Bay (96 μg / g), but lower in Culebra Bay (66 μg / g). Lead mean concentration was higher in Moin Bay (6.4 μg / g) and lower in Culebra Bay (3.0 μg / 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 Moin Bay and the Gulf of Nicoya showed an intermediate condition.

    Full Text Available The aim of the present study was to determine the presence of antibodies against Chlamydia abortus in specialized dairy farms. A total of 608 blood samples were collected during 2012 from 24 dairy farms located in the Northern regions of the provinces of Alajuela (15 and Heredia (9, and surveys were carried out to determine management practices in these farms. Serum samples were analyzed by enzyme-linked immunosorbent assay (ELISA to detect antibodies against C. abortus (sensitivity 100.0%, specificity 99.7%. Only one serum yielded positive results (S/P 62 %, two sera weak positive results (S/P 51% and 52%, respectively, while the remaining sera (n=605 were negative in ELISA. Six months later, 22 animals that showed S/P values >22% in ELISA were analyzed again, yielding all negative results. Blood, milk, conjunctival and vulvar swabs from these animals were analyzed by Polymerase Chain Reaction (PCR, and only one vulvar swab tested positive for Chlamydia spp. The analysis of the management practices and results obtained with ELISA and PCR lead us to conclude that C. abortus is not significantly present (<0.5% in dairy farms in the Northern regions of the provinces of Heredia and Alajuela in Costa Rica.

    Full Text Available This paper intends to introduce the three issues of Principia which will appear in a sequel honoring Newton da Costa’s 80th birthday. Instead of presenting the papers one by one, as it is common in presentations such as this one, we have left the papers speak by themselves, and instead we have preferred to present to the Brazilian readers, specialty to our students, some aspects of Newton da Costa’s conception of science and of the scientific activity, grounded on the concept of quasi-truth, which he contributed to develop in a rigorous way. Da Costa is known as one of the founding fathers of paraconsistent logic, but his contributions go also to the foundations of physics, theoretical computation, model theory, algebraic logic, lattice theory, applications of non-classical logics to law and technology, etc. But perhaps his main contribution was to provide a basis for the birth of a school of logic in our country (Brazil, serving as teacher and inspiring new researchers for generations. It is a pleasure to have had so enthusiastic acceptation from the editors of Principia to organize these volumes. I would like to thank the contributors and the editors of Principia, specially Prof. Cezar Mortari for his help in organizing the issue.

    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.

    A cross-sectional survey of a convenient sample of domestic cats from Costa Rica's greater metropolitan area was carried out to determine the prevalence of antibodies against feline herpesvirus type 1 (FHV-1), feline parvovirus (FPV), feline immunodeficiency virus (FIV) and antigens of feline leukemia virus (FeLV). Blood samples were collected from at least 96 cats from June 1998 to December 2001; data related to the individual cats and household variables were obtained using a questionnaire. Antibodies against FHV-1 were found in 71.9% of the cats sampled, but only 25.0% of them had a history of previous vaccination. The prevalence of FPV was 92.8%, and all positive cats showed protective antibodies titres; however, only 16.5% of them were previously vaccinated. Antigens of FeLV were detected in 16.7% of the sampled cats; 11 (64.7%) of the 17 positive cats were older than 1 year at the time of testing. No differences were found between the percentage of seropositive males and females. Antibodies against FIV were detected in 8.8% of the samples tested; 8 (88.8%) of the seropositive cats were older than 1 year of age, and a greater proportion of seropositive males (66.6%) was found.

    While anthropogenic impacts on parasitism of wildlife are receiving growing attention, whether these impacts vary in a sex-specific manner remains little explored. Differences between the sexes in the effect of parasites, linked to anthropogenic activity, could lead to uneven sex ratios and higher population endangerment. We sampled 1108 individual bats in 18 different sites across an agricultural mosaic landscape in southern Costa Rica to investigate the relationships between anthropogenic impacts (deforestation and reductions in host species richness) and bat fly ectoparasitism of 35 species of Neotropical bats. Although female and male bat assemblages were similar across the deforestation gradient, bat fly assemblages tracked their hosts closely only on female bats. We found that in female hosts, parasite abundance per bat decreased with increasing bat species richness, while in male hosts, parasite abundance increased. We hypothesize the differences in the parasite-disturbance relationship are due to differences in roosting behavior between the sexes. We report a sex-specific parasite-disturbance relationship and argue that sex differences in anthropogenic impacts on wildlife parasitism could impact long-term population health and survival.

Esse estudo constatou que a relação entre Lysimaco Ferreira da Costa e pessoas pertencentes ao grupo católico deu-se mais por questões políticas, do que por vias religiosas. Pelo que se apreende do estudo de sua sociabilidade, pode-se dizer que conservou, em seu círculo de amizades, católicos, protestantes e pessoas de crenças diversas, desde que essas não se opusessem, diante de circunstâncias de tomada de decisão e partido, aos seus interesses políticos. Palavras-chave: Lysimaco Ferreira da Costa; intelectuais da educação; ensino secundário.   LYSIMACO FERREIRA DA COSTA AND SECONDARYEDUCATION IN BRAZIL Abstract This article presents the insertion of Lysimaco Ferreira da Costa in the discussions concerning the direction of Brazilian education. He was an intellectual born in the state of Paraná. The period of the analysis ranges from 1920 and 1930 and its focus is the discussion of the secondary school. It emphasizes the ties and connections established in Lysimaco Ferreira da Costa’s network of relationships, his associations with intellectuals of other states, mainly from Rio de Janeiro and São Paulo. Through the data obtained in this study, it is possible to say that the affiliation between Lysimaco Ferreira da Costa and the Catholic group took place primarily due to political reasons rather than religious grounds. According to the study of his sociability, he maintained in his circle of friends both Catholics, Protestants and people of several beliefs, as long as they did not oppose to his political interests

  1. Challenges for implementing water quality monitoring and analysis on a small Costa Rican catchment

    The Costa Rican water regulatory framework (WRF) (2007), expresses the national concern about the degradation of surface water quality observed in the country since several years. Given the urgency of preserving and restoring the surface water bodies, and facing the need of defining a monitoring tool to classify surface water pollution, the Costa-Rican WRF relies on two water quality indexes: the so-called "Dutch Index" (D.I) and the Biological Monitoring Working Party adapted to Costa Rica (BMWP'CR), allowing an "easy" physicochemical and biological appraisal of the water quality and the ecological integrity of water bodies. Herein, we intend to evaluate whether the compound of water quality indexes imposed by Costa Rican legislation, is suitable to assess rivers local and global anthropogenic pressure and environmental conditions. We monitor water quality for 7 points of Liberia River (northern pacific region - Costa Rica) from March 2013 to July 2015. Anthropogenic pressures are characterized by catchment land use and riparian conditions. Environmental conditions are built from rainfall daily series. Our results show (i) the difficulties to monitor new sites following the recent implementation of the WRF; (ii) the statistical characteristics of each index; and (iii) a modelling tentative of relationships between water quality indexes and explanatory factors (land-use, riparian characteristics and climate conditions).

    Pseudocercospora fijiensis is the causal pathogen of black Sigatoka, a devastating disease of banana that can cause 20 to 80% yield loss in the absence of fungicides in banana crops. The genetic structure of populations of P. fijiensis in Costa Rica was examined and compared with Honduran and global populations to better understand migration patterns and inform management strategies. In total, 118 isolates of P. fijiensis collected from Costa Rica and Honduras from 2010 to 2014 were analyzed using multilocus genotyping of six loci and compared with a previously published global dataset of populations of P. fijiensis. The Costa Rican and Honduran populations shared haplotype diversity with haplotypes from Southeast Asia, Oceania, and the Americas but not Africa for all but one of the six loci studied. Gene flow and shared haplotype diversity was found in Honduran and Costa Rican populations of the pathogen. The data indicate that the haplotypic diversity observed in Costa Rican populations of P. fijiensis is derived from dispersal from initial outbreak sources in Honduras and admixtures between genetically differentiated sources from Southeast Asia, Oceania, and the Americas.

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

    1982-04-01

    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.

  4. International Uranium Resources Evaluation Project (IUREP) national favourability studies: Costa Rica

    International Nuclear Information System (INIS)

    1977-08-01

    Most parts of Costa Rica, except for the Quaternary volcanic belt, have neither been studied or mapped in detail. Concerning past exploration limited uranium exploration took place in the late 1960's but details are lacking. No additional information is available. A bibliography of Costa Rican geology (Dengo, 19t>2a) and the metallogenic map of Central America (1CAITI, 1970) do not report any uranium occurrences. Data on current exploration activities for uranium are lacking. Mining is essentially regulated by a 1953 code and a 1964 supplement, but the production and use of radioactive materials are controlled by the Costa Rican Atomic Energy Commission. New raining and petroleum laws reportedly are being considered. Mining rights are available with few restrictions to foreign nationals and corporations. Costa Rica contains no rocks older than Cretaceous. The Mesozoic continental clastic sequences of Honduras and northern Nicaragua do not extend this far south. The massive intrusions of acidic granites and syenites in the Talamanca ranges are probably older than the oldest formations now seen adjacent to them and could not have contributed to their mineralization except through weathering. There may be a faint possibility for uranium deposition in lodes and fracture zones within the granitic rocks, but no such deposits have been reported. Insofar as the sediments are concerned, only the shallow water faces of the marine sediments of the Caribbean coastal region offer the remotest possibilities. The uranium potential of Costa Rica is estimated, at less than 1,000 tonnes

    We present a design study of the Deep Insights Anywhere, Anytime (DIA2) platform, a web-based visual analytics system that allows program managers and academic staff at the U.S. National Science Foundation to search, view, and analyze their research funding portfolio. The goal of this system is to facilitate users' understanding of both past and currently active research awards in order to make more informed decisions of their future funding. This user group is characterized by high domain expertise yet not necessarily high literacy in visualization and visual analytics-they are essentially casual experts-and thus require careful visual and information design, including adhering to user experience standards, providing a self-instructive interface, and progressively refining visualizations to minimize complexity. We discuss the challenges of designing a system for casual experts and highlight how we addressed this issue by modeling the organizational structure and workflows of the NSF within our system. We discuss each stage of the design process, starting with formative interviews, prototypes, and finally live deployments and evaluation with stakeholders.

    Full Text Available O artigo teve o intuito de suscitar o debate acerca do fenômeno da corrupção na sociedade brasileira. Para tal, realizou-se uma análise de discursos veiculados em matérias do jornal Zero Hora/RS, destacando-se o que se produz a partir deles. Temos como base a Hermenêutica de Profundidade e se discorre acerca das influências ideológicas, das relações de poder e de dominação que se apresentaram. Percebeu-se a influência que a mídia exerce na produção de subjetividade contemporânea e na disseminação de algumas propostas. A pós-modernidade também traz atravessamentos que se acredita serem fundamentais para a compreensão do momento atual. Constatou-se que é necessário ter uma visão dialética acerca dos problemas, com a participação ativa de todos, relativizando opiniões e pensamentos distintos, mantendo um diálogo e troca entre os saberes. É necessário também um investimento na educação da população em geral, para que as pessoas possam pensar e questionar a realidade por si mesmas.

    Full Text Available Os estudos sobre mídias e novas tecnologias na educação ganham cada vez mais relevância mediante iniciativas que seguem uma tendência internacional de educação para a mídia e fomentam a participação na cultura digital. Entretanto, no Brasil ainda faltam materiais pedagógicos e metodologias de trabalho apropriadas para atividades dessa natureza. Nesse contexto, se insere o presente artigo, que discute metodologias destinadas à alfabetização para a mídia. O estudo aponta caminhos, calcados na metodologia inglesa, denominada media literacy, para trabalhar com a linguagem da mídia em sala de aula e expõe resultados de atividades aplicadas pelas autoras. Percebe-se, em linhas gerais, que a exploração da linguagem midiática no contexto educacional contribui para desenvolver o senso crítico, a criatividade, a expressividade, entre outras competências.

    The American Diabetes Association announced in 2012 that 86 million Americans were diagnosed with prediabetes compared to 79 million in 2010. Prediabetes + Me (PreDiaMe) is an innovative educational programme developed by pharmacy students at Nova Southeastern University College of Pharmacy, which provides collaborative interprofessional care for patients with prediabetes. A literature review using EBSCOhost, EMBASE, and MEDLINE databases searching the terms education, health services, interprofessional team, and prediabetes was conducted. Human studies published in English between 2006 and 2016 were included. Investigators interviewed a community pharmacist and a consultant pharmacist certified in diabetes education. Based on these interviews and the literature found, PreDiaMe was created to unite healthcare professionals through a three-step community outreach programme. The goal of PreDiaMe is to identify patients at risk of prediabetes, to decrease the prevalence of type 2 diabetes mellitus (T2DM), to reduce healthcare costs, and to improve the quality of life for patients with prediabetes. PreDiaMe benefits patients with prediabetes, the healthcare system, and pedagogy as it aims to decrease in the prevalence and economic burden and increase health outcomes of patients with prediabetes while being used as a tool to provide integrative education in health professional programmes.

  3. SMIFH2-mediated mDia formin functional inhibition potentiates chemotherapeutic targeting of human ovarian cancer spheroids.

    2016-03-25

    Due to a lack of effective screening or prevention protocol for epithelial ovarian cancer (EOC), there is a critical unmet need to develop therapeutic interventions for EOC treatment. EOC metastasis is unique. Initial dissemination is not primarily hematogenous, yet is facilitated through shedding of primary tumor cells into the peritoneal fluid and accumulating ascites. Increasingly, isolated patient spheroids point to a clinical role for spheroids in EOC metastasis. EOC spheroids are highly invasive structures that disseminate upon peritoneal mesothelium, and visceral tissues including liver and omentum. Selection for this subset of chemoresistant EOC cells could influence disease progression and/or recurrence. Thus, targeting spheroid integrity/structure may improve the chemotherapeutic responsiveness of EOC. We discovered a critical role for mammalian Diaphanous (mDia)-related formin-2 in maintaining EOC spheroid structure. Both mDia2 and the related mDia1 regulate F-actin networks critical to maintain cell-cell contacts and the integrity of multi-cellular epithelial sheets. We investigated if mDia2 functional inhibition via a small molecule inhibitor SMIFH2 combined with chemotherapeutics, such as taxol and cisplatin, inhibits the viability of EOC monolayers and clinically relevant spheroids. SMIFH2-mediated mDia formin inhibition significantly reduced both ES2 and Skov3 EOC monolayer viability while spheroid viability was minimally impacted only at the highest concentrations. Combining either cisplatin or taxol with SMIFH2 did not significantly enhance the effects of either drug alone in ES2 monolayers, while Skov3 monolayers treated with taxol or cisplatin and SMIFH2 showed significant additive inhibition of viability. ES2 spheroids were highly responsive with clear additive anti-viability effects with dual taxol or cisplatin when combined with SMIFH2 treatments. While combined taxol with SMIFH2 in spheroids showed an additive effect relative to single

  10. Carcinoma associated fibroblasts (CAFs) promote breast cancer motility by suppressing mammalian Diaphanous-related formin-2 (mDia2).

    The tumor microenvironment (TME) promotes tumor cell invasion and metastasis. An important step in the shift to a pro-cancerous microenvironment is the transformation of normal stromal fibroblasts to carcinoma-associated fibroblasts (CAFs). CAFs are present in a majority of solid tumors and can directly promote tumor cell motility via cytokine, chemokine and growth factor secretion into the TME. The exact effects that the TME has upon cytoskeletal regulation in motile tumor cells remain enigmatic. The conserved formin family of cytoskeleton regulating proteins plays an essential role in the assembly and/or bundling of unbranched actin filaments. Mammalian Diaphanous-related formin 2 (mDia2/DIAPH3/Drf3/Dia) assembles a dynamic F-actin cytoskeleton that underlies tumor cell migration and invasion. We therefore sought to understand whether CAF-derived chemokines impact breast tumor cell motility through modification of the formin-assembled F-actin cytoskeleton. In MDA-MB-231 cells, conditioned media (CM) from WS19T CAFs, a human breast tumor-adjacent CAF line, significantly and robustly increased wound closure and invasion relative to normal human mammary fibroblast (HMF)-CM. WS19T-CM also promoted proteasome-mediated mDia2 degradation in MDA-MB-231 cells relative to control HMF-CM and WS21T CAF-CM, a breast CAF cell line that failed to promote robust MDA-MB-231 migration. Cytokine array analysis of CM identified up-regulated secreted factors in WS19T relative to control WS21T CM. We identified CXCL12 as a CM factor influencing loss of mDia2 protein while increasing MDA-MB-231 cell migration. Our data suggest a mechanism whereby CAFs promote tumor cell migration and invasion through CXCL12 secretion to regulate the mDia2-directed cytoskeleton in breast tumor cells.

During October and November 1998 (rainy season, and December, February and March 1999 (dry season, larvae distribution of Petrolisthes armatus and associated decapods were sampled in three different sites at the Punta Morales peninsula, Gulf of Nicoya, Costa Rica. A total of 6014 decapod larvae were collected, and 73 belonged to the genus Petrolisthes spp. No significant total larval density differences were found between seasons (p>0.05; but there was a greater density of P. armatus and other decapod larvae (p>0.05 during the dry season. In addition, no significant variations on temperature and oxygen concentration were observed. P. armatus larval abundance was higher during low tide, in contrast with other decapod larvae. Significant differences among sites were found for other decapod larvae, but not for P. armatus. The only parameter that varied significantly between seasons was salinity and results demonstrate that this factor regulates temporal concentration of larvae. Moreover, flow-tide oscillations were the most important spatial factor in larval dynamics. We propose this mechanism: P. armatus liberates larvae during high tide; these larvae leave the coastal area during low tide and return to the rocky intertidal ecosystem during high tide, when they are

    The African hedgehog is one of the newly imported exotic pets which have been observed with increasing regularity in veterinary clinics in Costa Rica. Despite their popularity, information about their diseases is scarce. Within skin diseases of hedgehogs, mange caused by Caparinia spp. is a common diagnosis in other countries. Two adult African hedgehogs, one male and one female, were brought to a private clinic in Heredia, Costa Rica, with chronic pruritic dermatitis, scabs, nearly complete loss of spines, lethargy, dehydration, and weight loss. During physical exam, deposits of dry seborrhea were taken and processed for diagnosis. Microscopic examination revealed psoroptid mites identified as Caparinia tripilis. This is the first report of the presence of Caparinia tripilis in Costa Rica and, to the authors' knowledge, the rest of Central America.

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

    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.

    The aim of this article is to present a simple method of communication between two oral health professionals so that the problem can be conveyed easily and treatment options obtained equally easily and quickly, using current electronic communication technologies. Treatment of dental problems involves a thorough understanding of the underlying dental and medical conditions. The arena of dentistry being ever changing, with new specialties arising each year, it has become virtually impossible for an average dentist to keep track of all the treatment modalities available for various problems at a given time. It is the duty of a dentist, however, to treat his patients to the best of his ability. Professional ethics bind the other health professionals to render their opinion to the dentist so that the patient will ultimately get the best possible treatment. Method of communication is the only problem remaining in the path to achieving a total oral health care. DiaTreat is a unique method of clinical charting by which a dentist can incorporate all the ailments affecting his patient, and by withholding the patients name and address, can communicate with any of his colleagues for their opinion on the best treatment option for his patient. It is a new and innovative method of communication between a dentist and specialist. Even though it has some shortcomings of its own, on a wider range, the advantages far outweigh the drawbacks of the system. CLINICAL AND ACADEMIC SIGNIFICANCE: This can also be used by educational institutes for easy communication during interdisciplinary exchanges. Improvements need to be made yet to incorporate all the ailments known in dental discipline and make communication a comprehensive one.

Um é o diagnóstico de substituição da norma pelo risco como conceito básico por meio do qual os indivíduos na cultura ocidental pensam o poder de suas ações e, desse modo, habitam o tempo. Em outras palavras, esses conceitos orientam o modo como os indivíduos trabalham sobre seus corpos e estados mentais para conquistar um estado de ser no futuro tido como desejável. O segundo eixo aponta os fatores de mudança – a transformação recente do capitalismo e o desenvolvimento tecnocientífico – e propõe os modos como eles afetam a produção de subjetividade.

First, the diagnostic of the substitution of norm by risk as the basic concept through which Western individuals conceive the power of their actions and therefore inhabit time. These concepts orient the ways in which individuals work upon their bodies and mental states in order to attain a desirable stateof being in the future. The second axe posits a recent transformation in capitalism and techno-scientific developments as agents in the production of subjectivity.

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 = lambda a t + gamma S12 + a t typeEn este trabajo, se analizaron los datos de desembarque de tiburón de la flota pesquera artesanal en el Pacífico costarricense entre 1988 y 1997.

    The presence of resistance to clethodim in Poa annua populations was observed in onion fields in the highlands of Cartago, Costa Rica. Two experiments were conducted; the first one was carried out, in 2007, in a greenhouse at the Fabio Baudrit Moreno Agricultural Experiment Station (EEAFBM, in Spanish), with seeds of plants from a farm where clethodim has exercised good control (S population), and from another farm where clethodim has showed a deficient control (R population). Both S and R populations were treated with different doses of clethodim (0,5X, 1,0X, 1,5X and 2,0X), being X the recommended commercial dose. In this experiment, control of the R population was 44% and 17% at doses of 1.5X and 2.0X, respectively, whereas control of the S population was 100% at either of those doses. The second experiment was carried out in 2009, seeds of two other P. annua populations were collected in a similar way: one population from an area where weed control has been satisfactory (S), and the other population from an area of the farm where control was deficient (R). Seeds were sown, depending on the type, in plastic pots and sprayed with clethodim at doses of: 0. 1X, 2X, 4X, 8X, and 16X. There were significant differences in the reactions to clethodim of both P. annua populations The S population showed a higher percentage of control and less surviving plants than the R population. Several plants of the R population resisted up to 16X commercial doses of clethodim. Results of both experiments suggest the presence of P. annua populations resistant to clethodim. (author) [es

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

    The degree of inter-regional genetic diversity is explored in cattle of Costa Rica. 1498 DNA samples were collected of eight different regions of the country during the year 2013. Allelic frequencies and major population genetic parameters are calculated for eighteen microsatellite markers. An analysis of molecular variance is performed. The genetic distances between cattle of different regions are calculated. A high degree of diversity, with an average number of 14,6±1,01 alleles observed and 5,6+0,37 effective alleles per marker is observed at the national level. The heterozygosity observed (Ho) has been 0,76±0,01 and the expected (He) 0,81±0,01. Polymorphic information content (PIC) and inbreeding index (F_I_S) have been of 0,79±0,06 and 0,06±0,004, respectively. At the regional level, HO has varied from 0,73 ± 0,02 in the Central Sur region to 0,78 ±0,01 in the Huetar Norte region. Three clearly differentiated groups are shown by the dendrogram , with the Central Metropolitana and Central Occidental regions in a group: Huetar Caribe, Central Sur, Pacifico Central and Chorotega in a second group; and Huetar Norte and Brunca in a third intermediate group. Estimates of genetic differentiation R_S_T have been significant between regions of different groups and among regions of the same group have remained without being significant. Genetic differences between regions are related with differentiated proliferation of racial types according to their adaptability to the agroecological conditions and production systems prevailing in each region.

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

  6. Measuring Gases Using Drones at Turrialba Volcano, Costa Rica

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

    Full Text Available The population of Costa Rica (CR represents an admixture of major continental populations. An investigation of the CR population structure would provide an important foundation for mapping genetic variants underlying common diseases and traits. We conducted an analysis of 1,301 women from the Guanacaste region of CR using 27,904 single nucleotide polymorphisms (SNPs genotyped on a custom Illumina InfiniumII iSelect chip. The program STRUCTURE was used to compare the CR Guanacaste sample with four continental reference samples, including HapMap Europeans (CEU, East Asians (JPT+CHB, West African Yoruba (YRI, as well as Native Americans (NA from the Illumina iControl database. Our results show that the CR Guanacaste sample comprises a three-way admixture estimated to be 43% European, 38% Native American and 15% West African. An estimated 4% residual Asian ancestry may be within the error range. Results from principal components analysis reveal a correlation between genetic and geographic distance. The magnitude of linkage disequilibrium (LD measured by the number of tagging SNPs required to cover the same region in the genome in the CR Guanacaste sample appeared to be weaker than that observed in CEU, JPT+CHB and NA reference samples but stronger than that of the HapMap YRI sample. Based on the clustering pattern observed in both STRUCTURE and principal components analysis, two subpopulations were identified that differ by approximately 20% in LD block size averaged over all LD blocks identified by Haploview. We also show in a simulated association study conducted within the two subpopulations, that the failure to account for population stratification (PS could lead to a noticeable inflation in the false positive rate. However, we further demonstrate that existing PS adjustment approaches can reduce the inflation to an acceptable level for gene discovery.

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

    2013-12-01

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

    For several years, the University of Costa Rica, NASA Centers (e.g., JPL, ARC, GSFC/WFF, GRC) & NASA contractors-partners have made regular in situ measurements of aerosols & gases at Turrialba Volcano in Costa Rica, with aerostats (e.g., tethered balloons & kites), & free-flying fixed wing UAVs (e.g., Dragon Eye, Vector Wing 100, DELTA 150), at altitudes up to 12.5Kft ASL within 5km of the summit. Onboard instruments included gas detectors (e.g., SO2, CO2), visible & thermal IR cameras, air samplers, temperature pressure & humidity sensors, particle counters, & a nephelometer. Deployments are timed to support bimonthly overflights of the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) onboard the NASA Terra satellite (26 deployments to date). In situ observations of dilute plume SO2 concentrations (~1-20ppmv), plume dimensions, and associated temperature, pressure, & humidity profiles, validate detailed radiative transfer-based SO2 retrievals, as well as archive-wide ASTER band-ratio SO2 algorithms. Our recent UAV-based CO2 observations confirm high concentrations (e.g., ~3000ppmv max at summit jet), with 1000-1500ppmv flank values, and essentially global background CO2 levels (400ppmv) over distal surroundings. Transient Turrialba He detections (up to 20ppmv) were obtained with a small (~10kg) airborne mass spectrometer on a light aircraft—a UAV version (~3kg) will deploy there soon on the UCR DELTA 500.

    Full Text Available Este trabalho focaliza a homogeneidade da paisagem urbana das cidades de porte médio do interior do estado de São Paulo do ponto de vista de seus determinantes paisagísticos. A origem socioeconômica das cidades determina, em um primeiro momento, sua configuração, a qual, esgotado o estímulo inicial, passa a incorporar as imagens formais das grandes cidades. Estas imagens estão claramente representadas de um modo específico na paisagem urbana dessas cidades, evidenciando os reflexos formais e funcionais das paisagens dos grandes centros, e na geração de valores estéticos e de uso do espaço relacionados aos aspectos formais e visuais que se fazem presentes em suas paisagens. A legislação que define os padrões de ocupação urbana, os quais por sua vez definem a configuração física da paisagem, trabalha basicamente o espaço físico-territorial, alienando-se dos demais componentes da problemática urbana, e, desta forma, as cidades se homogeneízam. Ou seja, gera um discurso urbanístico pobre e o que se faz é generalista. A paisagem da cidade média paulista é então homogênea como conseqüência desta forma de ocupação homogênea. Como contraposição à paisagem homogênea, algumas condições ambientais e paisagísticas locais, como a presença de um rio ou de uma topografia acidentada, servem de início como determinantes para projetos urbanísticos/paisagísticos diferenciados e característicos para cada cidade, mas no momento seguinte os elementos da" moda" entram na composição da paisagem, descaracterizando o padrão diferenciado inicial.

    Full Text Available Este artigo pretende mostrar como os moradores de rua expõem sua trajetória de vida por meio das diferentes formas de expressão autobiográfica instauradas nas e pelas mídias sociais digitais. Discute-se o uso das novas tecnologias da web por moradores de rua, que, através das redes sociais, registram um modo de habitar o espaço social e se fazem visíveis na e para a sociedade que os marginaliza. Utiliza-se como aporte teórico-metodológico a Análise do Discurso de linha francesa na sua articulação com os Estudos Culturais no intuito de indicar como sites, blogs e páginas de Facebook, na diversidade de configuração multimodal que exploram, têm se revelado um espaço de manifestação de várias categorias de subalternos (SPIVAK, 2010, que, ao testemunharem sua forma de existência, reorganizam o vivido, oferecendo um entendimento das suas condições de existência. Foi realizado estudo exploratório de narrativas de moradores de rua, considerando-se como os eventos narrados participam de uma sequencialidade e temporalidade que caracterizam as textualidades autobiográficas. Concebidas como uma “reconstrução discursiva” (GUILHAUMOU, 2004, essas narrativas traduzem uma presença social e indicam movimentos de alteridade inerentes ao processo de biografização de si. Os resultados sinalizam a relação do testemunho individual com a história coletiva, pois ele participa da construção de uma memória plural. Cada narrativa classifica e, de alguma forma, situa os acontecimentos axiologicamente dentro de uma dada causalidade e no interior de um circuito enunciativo, o qual coloca o sujeito que se autobiografa como personagem nuclear.

    Energy Technology Data Exchange (ETDEWEB)

    Herrera, Alfonso Herrera

    1996-07-01

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

    Full Text Available O conhecimento da dinâmica das alterações nos parâmetros hematológicos e na cinética das proteínas de fase aguda em animais saudáveis nas primeiras semanas de vida é essencial para a interpretação correta dessas avaliações em situações de morbidez e para diferenciar animais sadios e enfermos de forma confiável. Com o intuito de avaliar a cinética desses parâmetros no primeiro mês de vida de bezerros de corte sadios, filhos de vacas primíparas ou pluríparas, amostras de sangue foram coletadas antes da ingestão de colostro e 1, 2, 7, 15 e 30 dias após o nascimento. Os parâmetros eritrocitários foram influenciados pelo número de partos das vacas e o leucograma mostrou alterações características de influência do cortisol fetal liberado por ocasião do nascimento. O teor sérico de proteína total aumentou significativamente após a ingestão do colostro. As concentrações de ceruloplasmina, haptoglobina e proteínas de pesos moleculares 33 kDa e 23 kDa aumentaram significativamente no primeiro dia de vida, seja pela resposta ao nascimento ou pela ingestão do colostro, enquanto os teores de transferrina, albumina e α1-glicoproteína ácida mantiveram-se relativamente estáveis nos primeiros dias de vida, aumentando gradualmente até os 30 dias de idade.

  15. Outdoor and indoor dose assessment using environmental thermoluminescence dosimeters (TLDs) in Costa Rica

    2003-01-01

    Costa Rica lies at the intersection of the Cocos and Caribbean plates in Central America. It has mountain ranges with many active volcanoes along its territory. Its soils are predominantly of volcanic origin. Natural radiation measurements utilising environmental CaF 2 :Dy thermoluminescence dosimeters were used for the first time in Costa Rica by the Dosimetry Section of the Atomic, Nuclear and Molecular Sciences Research Center of the University of Costa Rica. Seven hundred outdoor measurements were obtained in a 3.5-year period at eight different sites throughout the country. One hundred and seventy-four indoor readings were also collected at four sites for a 2-year period. Population-weighted averages give 82 nGy h -1 for outdoors and 130 nGy h -1 for indoors. The values lie on the upper range of worldwide reported values due to reported soil characteristics rich in uranium and potassium. A preliminary population-weighted value of 0.74 mSv/year for the effective dose is calculated for natural terrestrial gamma radiation in Costa Rica

    Maintained dedication to primary care has fostered a public health delivery system with exceptional outcomes in Costa Rica. For more than a decade, management commitments have been part of Costa Rican health reform. We assessed the effect of the Costa Rican management commitments on access and quality of care and on compliance with their intended objectives. We constructed seven hypotheses on opinions of primary care providers. Through a mixed qualitative and quantitative approach, we tested these hypotheses and interpreted the research findings. Management commitments consume an excessive proportion of consultation time, inflate recordkeeping, reduce comprehensiveness in primary care consultations, and induce a disproportionate consumption of hospital emergency services. Their formulation relies on norms in need of optimization, their control on unreliable sources. They also affect professionalism. In Costa Rica, management commitments negatively affect access and quality of care and pose a threat to the public service delivery system. The failures of this pay-for-performance-like initiative in an otherwise well-performing health system cast doubts on the appropriateness of pay-for-performance for health systems strengthening in less advanced environments.

  3. Protoptila (Trichoptera) of Costa Rica and a Review of the Central American Fauna

    Blahnik, R. J.; Holzenthal, R. W.

    2005-05-01

    Protoptila is the most diverse of the genera in the subfamily Protoptilinae of the family Glossosomatidae, currently with 80 species, but many more from the Neotropics awaiting description. Fourteen species occur in the United States, only one of which is also known to occur in Mexico. This compares to 38 species and one subspecies (or about half of the total for the genus) currently known from Central America, mostly described in papers by Mosely and Flint. Although the majority of these, or some 27 species, occur in Mexico, this probably more closely reflects the historical intensity of collecting rather than the real diversity by region. In Costa Rica, 11 species are currently known, 8 of which are restricted in distribution to Costa Rica, or Costa Rica and Panama, and only 3 with distributions extending to Mexico. We are describing an additional 8 species from Costa Rica, bringing to 19 the number of species now known from the country. This represents an incredible diversity for such a small country and also a very high level of implied endemism, even considering the likelihood that some of the species will be found to have wider distributions.

    Directory of Open Access Journals (Sweden)

    Julia A. Flagg

    2018-01-01

    Full Text Available Costa Rica has pledged to become the first nation to become carbon neutral. This event raises the important question of how to understand this contemporary form of climate politics, given that Costa Rica has made an almost negligible contribution to the problem of global climate change. To understand this pledge, a case study spanning about 200 years situates the pledge within the country’s unique historical profile. An analysis of interview data, archival research, and secondary data reveals that the pledge is the latest instance in Costa Rica’s unusual political tradition. This political tradition dates back to the area’s experience as a Spanish colony and as a newly independent nation. Several events, including the abolition of the army, the work on green development, and being awarded a Nobel Peace Prize were all foundational in forming Costa Rica’s tradition as a place that leads by example and stands for peace and protection of nature. The carbon neutral pledge extends the political tradition that has been established through these earlier events. This case highlights the importance of understanding contemporary environmental politics through an analysis of long-term, historical data.

El estudio aquí reportado analizó las condiciones socio-económicas de tres comunidades vecinas al Parque Nacional Braulio Carrillo (PNBC, en Costa Rica, identificó los problemas ambientales de los residentes de las mismas que se podrían agravar por causa del desarrollo turístico y determinó cómo y bajo qué condiciones los habitantes de la zona querían que se realizara el desarrollo turístico de las comunidades. Se entrevistaron 123 de un total de un total de 155 casas en las tres comunidades, y se utilizó una combinación de componentes principales y análisis factorial para analizar los datos. Los resultados indican que los vecinos entrevistados desean que el desarrollo turístico sea hecho sosteniblemente, y que además, se planifique, se establezcan requisitos claros, que la comunidad sea periódicamente informada, que sus lideres comunales participen activamente en el proceso, se establezcan programas para ayudar al desarrollo de micro-empresas eco-turísticas, y que se les brinde asistencia técnica y capacite en el desarrollo de proyectos eco-turísticos. Los problemas eventuales asociados a la calidad ambiental que habría que prestarles atención preferente son: ruido y tráfico excesivo, manejo de aguas negras y deforestación. El desarrollo turístico sostenible relacionado con el primer componente implicaría que este es un requisito básico de la calidad ambiental, la conservación y el uso sostenible del patrimonio histórico.

    The costa is a prominent striated fibre that is found in protozoa of the Trichomonadidae family that present an undulating membrane. It is composed primarily of proteins that have not yet been explored. In this study, we used cell fractionation to obtain a highly enriched costa fraction whose structure and composition was further analysed by electron microscopy and mass spectrometry. Electron microscopy of negatively stained samples revealed that the costa, which is a periodic structure with alternating electron-dense and electron-lucent bands, displays three distinct regions, named the head, neck and body. Fourier transform analysis showed that the electron-lucent bands present sub-bands with a regular pattern. An analysis of the costa fraction via one- and two-dimensional electrophoresis and liquid chromatography coupled with tandem mass spectrometry (LC-MS/MS) allowed the identification of 54 hypothetical proteins. Fourteen of those proteins were considered to be major components of the fraction. The costa of T. foetus is a complex and organised cytoskeleton structure made of a large number of proteins which is assembled into filamentous structures. Some of these proteins exhibit uncharacterised domains and no function related according to gene ontology, suggesting that the costa structure may be formed by a new class of proteins that differ from those previously described in other organisms. Seven of these proteins contain prefoldin domains displaying coiled-coil regions. This propriety is shared with proteins of the striated fibres of other protozoan as well as in intermediate filaments. Our observations suggest the presence of a new class of the cytoskeleton filaments in T. foetus. We believe that our data could auxiliate in determining the specific locations of these proteins in the distinct regions that compose the costa, as well as to define the functional roles of each component. Therefore, our study will help in the better understanding of the

    Medina, Stephanie Rae

    The purpose of this study was to explore the experiences of classroom teachers who participated in a science-focused study abroad during their time as a preservice teacher and to explore how they are using their study abroad experiences in science curriculum planning and in classroom instruction. This study is guided by two research questions: 1) what are the study abroad experiences that have influenced classroom teachers; and, 2) how do classroom teachers incorporate study abroad experiences into science curriculum planning and instruction in the classroom? Participants were two in-service science teachers from schools located in the Southwestern United States. The participants were enrolled in the course, Environmental Science and Multicultural Experience for K-8 Teachers offered through the Department of Educational Leadership, Curriculum and Instruction during their time as preservice teachers. The course included a two-week study abroad component in Costa Rica. Participants spent their mornings observing a monolingual, Spanish-speaking elementary classroom followed by a faculty-led multicultural seminar. Afternoons during the study abroad experience were dedicated to field science activities such as quantifying plant and animal biodiversity, constructing elevation profiles, determining nutrient storage in soil, and calculating river velocity. Throughout the course students participated in science-focused excursions. A cross case study design was used to answer the two research questions guiding this dissertation study. Data collection included participant-created concept maps of the science experiences during the study abroad experience, in-depth interviews detailing the study abroad experience and classroom instruction, and participant reflective journal entries. Cross-caseanalysis was employed to explore the uniqueness of each participant's experience and commonalities between the cases. Trustworthiness was established by utilizing multiple sources of data

    The relationship of education, psychiatric diagnoses, and use of psychotropic medication has been explored in the United States, but little is known about this relationship in poorer countries, despite the high burden of mental illness in these countries. This study estimated educational gradients in diagnosis and psychotropic drug use in the United States and Costa Rica, a middle-income country with universal health insurance. Analyses were conducted by using data of older adults (≥60) from the 2005 U.S. Medical Expenditure Panel Survey (N=4,788) and the 2005 Costa Rican Longevity and Healthy Aging Study (N=2,827). Logistic regressions examined the effect of education level (low, medium, or high) and urban residence on the rates of self-reported mental health diagnoses, screening diagnosis, and psychotropic medication use with and without an associated psychiatric diagnosis. Rates of self-reported diagnoses were lower in the United States (12%) than in Costa Rica (20%), possibly reflecting differences in survey wording. In both countries, the odds of having depression were significantly lower among persons with high education. In Costa Rica, use of psychotropic medication among persons with self-reported diagnoses increased by education level. The educational gradients in medication use were different in the United States and Costa Rica, and stigma and access to care in these countries may play an important role in these differences, although type of insurance did not affect educational gradients in the United States. These analyses increase the evidence of the role of education in use of the health care system.

  3. Enhancing Outreach using Social Networks at the National Seismological Network of Costa Rica

    Costa Rica has a very high seismicity rate and geological processes are part of everyday life. Traditionally, information about these processes has been provided by conventional mass media (television and radio). However, due to the new trends in information flow a new approach towards Science Education is necessary for transmitting knowledge from scientific research for the general public in Costa Rica. Since 1973, the National Seismological Network of Costa Rica (RSN: UCR-ICE) studies the seismicity and volcanic activity in the country. In this study, we describe the different channels to report earthquake information that the RSN is currently using: email, social networks, and a website, as well as the development of a smartphone application. Since the RSN started actively participating in Social Networks, an increase in awareness in the general public has been noticed particularly regarding felt earthquakes. Based on this trend, we have focused on enhancing public outreach through Social Media. We analyze the demographics and geographic distribution of the RSN Facebook Page, the growth of followers, and the significance of their feedback for reporting intensity data. We observe that certain regions of the country have more Facebook activity, although those regions are not the most populated nor have a high Internet connectivity index. We interpret this pattern as the result of a higher awareness to geological hazards in those specific areas. We noticed that the growth of RSN users on Facebook has a strong correlation with the seismic events as opposed to Twitter that displays a steady growth with no clear correlations with specific seismic events. We see the Social Networks as opportunities to engage non-science audiences and encourage the population to participate in reporting seismic observations, thus providing intensity data. With the increasing access to Internet from mobile phones in Costa Rica, we see this approach to science education as an opportunity

    Costa Rica has one of the greatest percentages (26%) of protected land in the world. The National Protected Areas System (NPAS) of Costa Rica was established in 1976 and currently includes >190 protected areas within seven different protection categories. The effectiveness of the NPAS to represent species, populations, and areas with high species richness has not been properly evaluated. Such evaluations are fundamental to understand what is necessary to strengthen the NPAS and better protect biodiversity. We present a novel assessment of NPAS effectiveness in protecting mammal species. We compiled the geographical ranges of all terrestrial Costa Rican mammals then determined species lists for all protected areas and the estimated proportion of each species’ geographic range protected. We also classified mammal species according to their conservation status using the IUCN Red List of Threatened Species. We found almost complete representation of mammal species (98.5%) in protected areas, but low relative coverage (28.3% on average) of their geographic ranges in Costa Rica and 25% of the species were classified as underprotected according to a priori representation targets. Interestingly, many species-rich areas are not protected, and at least 43% of cells covering the entire country are not included in protected areas. Though protected areas in Costa Rica represent species richness well, strategic planning for future protected areas to improve species complementarity and range protection is necessary. Our results can help to define sites where new protected areas can have a greater impact on mammal conservation, both in terms of species richness and range protection. PMID:25970293

    Describe the relationship between the attitude towards violence against women (VAW) of professionals of the health of primary care with variables such professional satisfaction, workload, orientation of professional practice, knowledge, training and use of network in Catalonia and Costa Rica. Cross-exploratory and comparative study. Primary care in Barcelona and nearby counties and the Greater Metropolitan Area (GAM) of Costa Rica. 235 primary health professionals of Medicine, Nursing, Psychology and Social Work. Questionnaire with eight sections about attitudes, professional satisfaction, and orientation of professional practice, workload, knowledge, training and use of network. Three types of analysis were carried out: a descriptive one by country; a bivariate analysis; and a multivariable linear regression model. Primary Health Professionals attitudes towards VAW health were similar in both contexts (Catalonia: 3.90 IC 95% 3.84-3.96; Costa Rica: 4.03 IC 95% 3.94-4.13). The variables associated with attitudes towards VAW were: Use of network resources (B=0.20, 95% CI -0.14-0.25, P=<.001), Training (B=0.10, 95% CI 0.04 to 0.17, P=<0.001), and country, Costa Rica (B=0.16, 95% CI 0.06 to 0.25, P=<0.001). There was no interaction between the country and the other variables, suggesting that the association between the variables and the attitude is similar in both countries. The results suggest that increased use of network resources and training are related to a positive attitude towards VWA in primary health professionals, both in Catalonia and Costa Rica.

Existe consenso en la literatura económica en que hay una correlación positiva entre incertidumbre inflacionaria y la magnitud de la tasa de inflación, lo cual, como lo señaló Friedman (1977, representa uno de los costos asociados con la persistencia inflacionaria. Esto es porque tal incertidumbre dificulta la toma de decisiones óptimas por parte de los agentes económicos.La evidencia empírica, para el periodo 1954:01-2002:08, apoya la hipótesis de que para el caso de Costa Rica mientras mayor es la inflación mayor es la incertidumbre respecto a esta variable. En los últimos siete años (1997-2002 la incertidumbre presenta la variación media más baja de todo el periodo. Además, se identifica un efecto asimétrico de la inflación sobre la incertidumbre inflacionaria, es decir, la incertidumbre inflacionaria tiende a incrementarse más para el siguiente periodo cuando la inflación pronosticada está por debajo de la inflación actual, que cuando la inflación pronosticada está por arriba de la tasa observada de inflación. Estos resultados tienen una clara implicación para la política monetaria. Para minimizar la dificultad que la inflación causa en la toma óptima de decisiones de los agentes económicos es necesario perseguir no solamente un nivel bajo de inflación sino que también sea estable.AbstractThis paper estimates a measure of

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

    Optimal management of chronic diseases, such as type 2 diabetes (T2D) and obesity, requires patient-provider communication and proactive self-management from the patient. Mobile apps could be an effective strategy for improving patient-provider communication and provide resources for self-management to patients themselves. The objective of this paper is to describe the development of a mobile tool for patients with T2D and obesity that utilizes an integrative approach to facilitate patient-centered app development, with patient and physician interfaces. Our implementation strategy focused on the building of a multidisciplinary team to create a user-friendly and evidence-based app, to be used by patients in a home setting or at the point-of-care. We present the iterative design, development, and testing of DiaFit, an app designed to improve the self-management of T2D and obesity, using an adapted Agile approach to software implementation. The production team consisted of experts in mobile health, nutrition sciences, and obesity; software engineers; and clinicians. Additionally, the team included citizen scientists and clinicians who acted as the de facto software clients for DiaFit and therefore interacted with the production team throughout the entire app creation, from design to testing. DiaFit (version 1.0) is an open-source, inclusive iOS app that incorporates nutrition data, physical activity data, and medication and glucose values, as well as patient-reported outcomes. DiaFit supports the uploading of data from sensory devices via Bluetooth for physical activity (iOS step counts, FitBit, Apple watch) and glucose monitoring (iHealth glucose meter). The app provides summary statistics and graphics for step counts, dietary information, and glucose values that can be used by patients and their providers to make informed health decisions. The DiaFit iOS app was developed in Swift (version 2.2) with a Web back-end deployed on the Health Insurance Portability and

    Full Text Available As análises referentes à criminalidade nos/dos lugares, através da mídia impressa, produziram uma reflexão sobre as representações do espaço e os espaços de representação na/da metrópole de Salvador. Os dados utilizados para análise foram extraídos dos jornais A Tarde e Correio da Bahia, no ano de 2009, e envolveram os seguintes dados: tipos de violência, localidades de ocorrência dos delitos e caracterizações de vítimas. Os resultados demonstraram o reconhecimento da heterogeneidade dos lugares na/da metrópole de Salvador, mas sem produzir uma análise das contradições vivenciadas em tais espaços. As descrições dos atos violentos, das localidades e das pessoas, muitas vezes, foram copiadas de boletins de ocorrência da polícia. A heterogeneidade dos lugares quando não aprofundada e não inter-relacionada com contextos vividos nas metrópoles cristaliza as representações dos espaços e reduz, por exemplo, a problemática da violência a um mero aspecto da criminalidade. O presente artigo defende que para a análise do lugar é preciso o aprofundamento do espaço vivido articulado aos espaços concebidos e percebidos, algo já considerado importante pelos jornalistas, mas praticado por poucos, no processo de escrita das notícias dos atos violentos no Brasil.

    The outcome and complications which developed in 8 hemodialysis patients who received 12 DiaTAP bioCarbon button vascular-access devices were reviewed. All patients had a poor vascular access history. Three of twelve devices have been replaced because of thrombosis and two because of infection. Four patients have had 10 episodes of reduced blood flow. Streptokinase infusion into the DiaTAP button led to improved blood flow in 8 of 10 episodes. The 6-month survival rate of the DiaTAP access device was 67% and the average functioning life was 9.4 months. It was a valuable form of access when others had failed.

    Colonially-nesting birds often nest in coastal areas, along rivers, or near other bodies of water that also are potentially polluted from industrial, agricultural or urban development. The levels of heavy metals and selenium were examined in the feathers of young wood storks Mycteria americana nesting in Northeastern Florida and from adult and young storks nesting on the Tempisque River on the west coast of Costa Rica. There were no significant yearly differences among the chicks from Costa Rica. Concentration of mercury, cadmium, and lead were significantly higher in the chicks from Florida compared to those from Costa Rica. Adult wood storks at Costa Rica had significantly higher levels of lead, cadmium, selenium, and manganese than young from the same colony.

    Full Text Available Food habits of 15 species of frugivorous bats were studied at La Selva Biological Station, Costa Rica. Eight hundred and fifty-four (854 fecal samples and 169 samples from fruit parts and seeds discarded by bats beneath feeding roosts were analyzed. During eight months of study, 47 fruit species consumed by bats were identified. Five plant genera (Cecropia, Ficus, Piper, Solanum, and Vismia constituted 85% of all plants found in fecal samples. Feeding niche breadth differed significantly among the six most common species of frugivorous bats (Artibeus jamaicensis, Carollia sowelli, C. castanea, C. perspicillata, Dermanura sp., and Glossophaga commissarisi. All species, except for Dermanura sp., showed a diet dominated by one or two plant species. This suggests a pattern of resource partitioning at a generic level, in which Carollia consumed mainly Piper, Artibeus consumed Ficus and Cecropia, and Glossophaga consumed Vismia. Cluster analysis revealed higher values of food niche overlap in congeneric species than among species of different genera. Results show that if food is a limiting factor, mechanisms other than trophic selection must reduce interspecific interference or competition for food in this frugivorous bat guild. Rev. Biol.

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

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

Además, se caracterizó a ese segmento poblacional a partir de diferentes variables: sexo, edad, estado civil y distribución geográfica. También se abordaron otros aspectos como fueron: alfabetismo, nivel de educación, ocupación, jefatura de hogar y vivienda. Entre los hallazgos más destacables se encuentra la permanencia, en los registros censales del siglo XX, de un concepto de discapacidad basado en la deficiencia, lo que definió los criterios de clasificación para esa población en esas fuentes. Asimismo se constató, por una parte, la asociación entre discapacidad e inequidad en esa centuria y, por la otra, la fragilidad de los vínculos de parentesco en ese grupo poblacional con respecto al conjunto de hogares de Costa Rica a fines de ese siglo. Las fuentes empleadas en esta investigación fueron los censos de población de Costa Rica del siglo XX.

    Full Text Available From 1993 to 1997, we observed Scarlet Macaw (Ara macao feeding behavior in Central Pacific Costa Rica. Feeding data acquired in this study were not collected systematically, but opportunistically whenever macaws were observed feeding. To supplement feeding observations, we conducted interviews with local residents. Scarlet Macaws fed on seeds, fruits, leaves, flowers and/or bark of 43 plant species. Various plant parts eaten by macaws from several tree species contain secondary compounds toxic to humans, and additional species included in their diet are nonnative, introduced for agricultural purposes. Important macaw feeding tree species are Ceiba pentandra, Schizolobium parahybum, and Hura crepitans; these species are also crucial to this macaw population because of nest cavities they provide. The results of this study contribute to the conservation of Scarlet Macaws in Central Pacific Costa Rica through promoting protection of individual trees, and through local elementary school reforestation programs focusing on tree species that macaws use for feeding and/or nesting. Scarlet Macaw conservation is extremely important, as numerous population pressures have caused significant declines in macaw numbers in Costa Rica. Rev. Biol. Trop. 54 (3: 919-926.

  5. Ambient Tremor, But No Triggered Tremor at the Northern Costa Rica Subduction Zone

    Swiecki, Z.; Schwartz, S. Y.

    2010-12-01

    Non-volcanic tremor (NVT) has been found to be triggered during the passage of surface waves from various teleseismic events in locations around the world including Cascadia, Southwest Japan, Taiwan, and California. In this study we examine the northern Costa Rica subduction zone for evidence of triggered tremor. The Nicoya Peninsula segment of the northern Costa Rica margin experiences both slow-slip and tremor and is thus a prime candidate for triggered tremor observations. Eleven teleseismic events with magnitudes (Mw) greater than 8 occurring between 2006 and 2010 were examined using data from both broadband and short period sensors deployed on the Nicoya Peninsula, Costa Rica. Waveforms from several large regional events were also considered. The largest teleseismic and regional events (27 February 2010 Chile, Mw 8.8 and 28 May 2009 Honduras, Mw 7.3) induced peak ground velocities (PGV) at the NIcoya stations of ~2 and 6 mm/s, respectively; larger than PGVs in other locations that have triggered tremor. Many of the earthquakes examined occurred during small episodes of background ambient tremor. In spite of this, no triggered tremor was observed during the passage of seismic waves from any event. This is significant because other studies have demonstrated that NVT is not triggered everywhere by all events above some threshold magnitude, indicating that unique conditions are required for its occurrence. The lack of triggered tremor at the Costa Rica margin can help to better quantify the requisite conditions and triggering mechanisms. An inherent difference between the Costa Rica margin and the other subduction zones where triggered tremor exists is its erosional rather than accretionary nature. Its relatively low sediment supply likely results in a drier, lower pore fluid pressure, stronger and less compliant thrust interface that is less receptive to triggering tremor from external stresses generated by teleseismic or strong local earthquakes.

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.

    Full Text Available FUNDAMENTO: O Acidente Vascular Cerebral (AVC constitui uma das primeiras causas de morte a nível mundial. A importância do espessamento da íntima-média na estratificação de risco cardiovascular tem sido recorrentemente estudada; contudo, essa relação gera ainda alguma controvérsia. OBJETIVOS: Determinar se o espessamento da íntima-média na Artéria Carótida Comum (ACC pode ser utilizado como um marcador independente de alto risco para a ocorrência do AVC. MÉTODOS: A amostra compreende um grupo de 948 doentes consecutivamente estudados por Triplex Scan Cervical no período compreendido entre janeiro de 2004 e junho de 2009. Esses doentes foram agrupados em razão da presença ou ausência de AVC recente, do que resultou um grupo de doentes com AVC Isquémico (AVC I (n = 452, 48%, outro com AVC Hemorrágico (AVC H (n = 22, 2% e um grupo de doentes Sem Eventos (n = 474, 50%. RESULTADOS: Na análise de regressão logística ajustada para fatores de risco cardiovascular clássicos, o espessamento da íntima-média na ACC associou-se significativamente e de forma aproximadamente linear com o AVC I (Odds Ratio = 1.808, Intervalo de Confiança: 1.291-2.534, p = 0,01, mas não com o AVC H (p = ns. Uma interação significativa com a idade foi também encontrada, demonstrando-se uma capacidade discriminativa do risco de AVC I maior em indivíduos com idade inferior a 50 anos. CONCLUSÕES: O espessamento da íntima-média na ACC revelou-se um preditor de risco independente para o AVC I, mas não para AVC H reforçando assim a utilidade da sua avaliação na prática clínica.

  16. Customized Consensus Spectral Library Building for Untargeted Quantitative Metabolomics Analysis with Data Independent Acquisition Mass Spectrometry and MetaboDIA Workflow.

    Data independent acquisition-mass spectrometry (DIA-MS) coupled with liquid chromatography is a promising approach for rapid, automatic sampling of MS/MS data in untargeted metabolomics. However, wide isolation windows in DIA-MS generate MS/MS spectra containing a mixed population of fragment ions together with their precursor ions. This precursor-fragment ion map in a comprehensive MS/MS spectral library is crucial for relative quantification of fragment ions uniquely representative of each precursor ion. However, existing reference libraries are not sufficient for this purpose since the fragmentation patterns of small molecules can vary in different instrument setups. Here we developed a bioinformatics workflow called MetaboDIA to build customized MS/MS spectral libraries using a user's own data dependent acquisition (DDA) data and to perform MS/MS-based quantification with DIA data, thus complementing conventional MS1-based quantification. MetaboDIA also allows users to build a spectral library directly from DIA data in studies of a large sample size. Using a marine algae data set, we show that quantification of fragment ions extracted with a customized MS/MS library can provide as reliable quantitative data as the direct quantification of precursor ions based on MS1 data. To test its applicability in complex samples, we applied MetaboDIA to a clinical serum metabolomics data set, where we built a DDA-based spectral library containing consensus spectra for 1829 compounds. We performed fragment ion quantification using DIA data using this library, yielding sensitive differential expression analysis.

  17. Loss of RhoB expression enhances the myelodysplastic phenotype of mammalian diaphanous-related Formin mDia1 knockout mice.

    Directory of Open Access Journals (Sweden)

    Aaron D DeWard

    Full Text Available Myelodysplastic syndrome (MDS is characterized by ineffective hematopoiesis and hyperplastic bone marrow. Complete loss or interstitial deletions of the long arm of chromosome 5 occur frequently in MDS. One candidate tumor suppressor on 5q is the mammalian Diaphanous (mDia-related formin mDia1, encoded by DIAPH1 (5q31.3. mDia-family formins act as effectors for Rho-family small GTP-binding proteins including RhoB, which has also been shown to possess tumor suppressor activity. Mice lacking the Drf1 gene that encodes mDia1 develop age-dependent myelodysplastic features. We crossed mDia1 and RhoB knockout mice to test whether the additional loss of RhoB expression would compound the myelodysplastic phenotype. Drf1(-/-RhoB(-/- mice are fertile and develop normally. Relative to age-matched Drf1(-/-RhoB(+/- mice, the age of myelodysplasia onset was earlier in Drf1(-/-RhoB(-/- animals--including abnormally shaped erythrocytes, splenomegaly, and extramedullary hematopoiesis. In addition, we observed a statistically significant increase in the number of activated monocytes/macrophages in both the spleen and bone marrow of Drf1(-/-RhoB(-/- mice relative to Drf1(-/-RhoB(+/- mice. These data suggest a role for RhoB-regulated mDia1 in the regulation of hematopoietic progenitor cells.

    2017-04-01

    Full Text Available Available data shows an increase in international migration departing from Costa Rica, mainly to the United States. Based on the data obtained from two surveys conducted with potential emigrants and families with members living abroad, this paper is aimed at understanding their reasons for emigrating. In addition, some socio-economic impacts in four suburbs with high rates of emigration are identified. From a political economy approach, the most appropriate framework to better understand these emigration cases is discussed.  Moreover, the transformation of the employment and productive matrix followed by Costa Rica during the last three decades, as well as the country’s form of insertion into the international economy are two structural factors strongly linked to the emigration of the subjects studied in this paper.

    Costa Rica has shown how a small developing country can grab the bull of environmental degradation by the horns, and reverse one of the highest deforestation rates in Latin America to become the poster child of environment success. Key to its achievement has been the country's payments for environmental services (PES) programme, which began in 1997 and which many countries are now looking to learn from, especially as water markets and schemes to reward forest conservation and reduced deforestation (REDD+) grow. Within Costa Rica too, there is a need to first reflect on how the contexts for, and challenges facing, PES have changed; and continue building a robust programme that can ensure the coming decade is as successful as the past one.

    Full Text Available The MSME Observatory has been studying MSMEs in Costa Rica. Its findings show that for every formal enterprise, there are 2.4 semi-formal ones. The latter refers to those enterprises that have already started the formalization process with the corresponding municipality but that still do not have all the formalization requirements.Owing to the importance of the semi-formal sector in the economic activity of Costa Rica, this study analyzed this business park and the role of municipal management concerning MSMEs, calculated the correlation among semi-formality, competitiveness, and development, and finally, proposed a cluster design to deal with the state of affairs. It should be noted that this type of analysis has never been undertaken in the country.

This work seeks to create a thoughtful look regarding the existing indigenous education model in Costa Rica in general– and particularly in Talamanca. A methodology based on collaborative action research with indigenous teachers in the region of Talamanca Bribri and Talamanca Cabécar was used as a starting point. This methodology combined focus group discussions and individual interviews with a qualitative approach that allowed generating a series of critical impressions about the education system where they work. All this will lead to a summary of insights and specific recommendations that would strengthen the educational system for the indigenous population of Talamanca and would allow moving towards a true model of Intercultural Bilingual Education.

    Amphibians, turtles, mice and birds from a protected Costa Rican wildland were contaminated with organochlorine pesticides and metabolites. - Amphibians, turtles, birds (mostly passerines) and mice collected from a conservation area in northwestern Costa Rica were analyzed for organochlorine (OC) pesticide contamination. Six of 39 amphibians (three of eight species), three of six turtles (two species), one of eight mice (one species) and 19 of 55 birds (five of seven species) contained OCs at levels up to 580 ng/g. The most frequently detected compound in 23 of 108 organisms was p,p'DDE. Dieldrin, delta-BHC, heptachlor, p,p'DDD, and endosulfan II were each found in at least four organisms, while eight other OCs were found in at least one organism. The presence of OCs in taxa from the conservation area indicates the likelihood of long-distance transport of such compounds through the atmosphere.

  7. Tracking performance of unbalanced QPSK demodulators. I - Biphase Costas loop with passive arm filters

    Simon, M. K.; Alem, W. K.

    1978-01-01

    Unbalanced quadriphase-shift-keying (QPSK) is an attractive means for transmitting two digital data streams which in general have different average powers, data rates, and data formats. Previous analyses of the tracking performance of Costas loop demodulators of unbalanced QPSK have accounted only for the filtering effect produced by the loop's two arm filters on the equivalent additive noise perturbing the loop. When the bandwidth of these filters is selected on the basis of the order of the data rate, as is typical of optimum Costas loop design, the filtering degradations of the data modulations themselves and the cross-modulation noise produced by their multiplication in the loop often cannot be neglected. The purpose of this paper is to incorporate these additional filtering effects into the analysis. Many of the results obtained herein are in the form of closed-form expressions which can easily be evaluated numerically for design and performance prediction purposes.

    Since 1984, the Seismic Network of the Volcanological and Seismological Observatory of Costa Rica, Universidad Nacional (OVSICORI-UNA) has been recording and registering the seismicity in Costa Rica. Before September 2012, the earthquakes registered by this seismic network in northwestern Costa Rica were moderate to small, except the Cóbano earthquake of March 25, 1990, 13:23, Mw 7.3, lat. 9.648, long. 84.913, depth 20 km; a subduction quake at the entrance of the Gulf of Nicoya and generated peak intensities in the range of MM = VIII near the epicentral area and VI-VII in the Central Valley of Costa Rica. Six years before the installation of the seismic network, OVSICORI-UNA registered two subduction earthquakes in northwestern Costa Rica, specifically on August 23, 1978, at 00:38:32 and 00:50:29 with magnitudes Mw 7.0 (HRVD), Ms 7.0 (ISC) and depths of 58 and 69 km, respectively (EHB Bulletin). On September 5, 2012, at 14:42:02.8 UTC, the seismic network OVSICORI-UNA registered another large subduction earthquake in Nicoya peninsula, northwestern Costa Rica, located 29 km south of Samara, with a depth of 21 km and magnitude Mw 7.6, lat. 9.6392, long. 85.6167. This earthquake was caused by the subduction of the Cocos plate under the Caribbean plate in northwestern Costa Rica. This earthquake was felt throughout the country and also in much of Nicaragua. The instrumental intensity map for the Nicoya earthquake indicates that the earthquake was felt with an intensity of VII-VIII in the Puntarenas and Nicoya Peninsulas, in an area between Liberia, Cañas, Puntarenas, Cabo Blanco, Carrillo, Garza, Sardinal, and Tamarindo in Guanacaste; Nicoya city being the place where the maximum reported intensity of VIII is most notable. An intensity of VIII indicates that damage estimates are moderate to severe, and intensity VII indicates that damage estimates are moderate.

    The eastern San Francisco Bay region (Contra Costa and Alameda Counties, California) is a geologically complex area divided by faults into a suite of tectonic blocks. Each block contains a unique stratigraphic sequence of Tertiary sediments that in most blocks unconformably overlie Mesozoic sediments. Age and environmental interpretations based on analysis of microfossil assemblages are key factors in interpreting geologic history, structure, and correlation of each block. Much of this data, however, is distributed in unpublished internal reports and memos, and is generally unavailable to the geologic community. In this report the U.S. Geological Survey microfossil data from the Tertiary sediments of Alameda and Contra Costa counties are analyzed and presented in a digital database, which provides a user-friendly summary of the micropaleontologic data, locality information, and biostratigraphic and ecologic interpretations.

    Scientific knowledge about hydroarsenicism must be disclosed in Latin America. The presence of arsenic has been detected in waters of Costa Rica that have been used for human consumption, in areas of risk; specifically in the province of Cartago, in the cantons of Oreamuno, Central, Paraiso and Alvarado. A quantification of reduced form trivalent arsenic was performed with the methodology of the 7062 Environmental Protection Agency of the United States, through volatile metal hydride generation by flame atomic absorption. The analyzed samples have determined that maintaining the maximum extent permitted by current legislation Costa Rican, 10μg/L. Research areas have corresponded to areas of high risk for its volcanic nature. The vast water supply of the cantons under study, with areas of relative protection circling recharge areas of springs, has caused the population to consume water source underground, but surface direct influence, less influence of volcanic rocks that are found at greater depths.

    Full Text Available This paper analyzes the economic contribution of married and cohabiting women to the household income, in comparison to the income their partners generate, in Costa Rica.  From a perspective of gender roles, human capital theory and female labor participation, this paper examines what variables influence the probability of contribution.  Based on data by the 2014 National Household Survey, this study found that 51% percent of married or cohabiting women do not generate any income, which shows there is an unequal economic relationship in half of Costa Rican households and the males assume the breadwinning role.  Household chores and the number of children reduce the probability of economic contribution.  On the other hand, women with more years of schooling have a higher probability to contribute equally to the couple’s total income.

    Amphibians, turtles, mice and birds from a protected Costa Rican wildland were contaminated with organochlorine pesticides and metabolites. - Amphibians, turtles, birds (mostly passerines) and mice collected from a conservation area in northwestern Costa Rica were analyzed for organochlorine (OC) pesticide contamination. Six of 39 amphibians (three of eight species), three of six turtles (two species), one of eight mice (one species) and 19 of 55 birds (five of seven species) contained OCs at levels up to 580 ng/g. The most frequently detected compound in 23 of 108 organisms was p,p'DDE. Dieldrin, delta-BHC, heptachlor, p,p'DDD, and endosulfan II were each found in at least four organisms, while eight other OCs were found in at least one organism. The presence of OCs in taxa from the conservation area indicates the likelihood of long-distance transport of such compounds through the atmosphere

    Full Text Available O presente artigo, em uma abordagem ensaística, tem como objetivo analisar efeitos psicossociais na constituição de modos de subjetivação e em famílias a partir da emergência daquilo que vem sendo nomeado de a "nova classe média brasileira". Para isto, primeiramente foi feita revisão bibliográfica de como a sociologia, economia e antropologia vem conceituando e caracterizando esta nova classe social, considerando que não há estudos acerca desse tema na Psicologia. A partir do diálogo com fontes midiáticas, buscou-se pensar como vem sendo operada a construção de um "estilo de vida" marcado pela tentativa de planejamento do futuro, consumo e meritocracia. Tais características mostram-se importantes formas de aproximação com a classe média tradicional. Por fim, buscou-se entender como famílias vêm vivenciando tais mudanças em seu cotidiano, organização e relações.

    Full Text Available Trinta bezerros machos da raça Holandesa foram alojados em piquetes a partir do quinto dia de vida, distribuídos em dois grupos. Todos os animais foram alimentados com concentrado comercial peletizado, tendo o primeiro grupo recebido leite integral (grupo-controle e o outro, sucedâneo formulado com proteínas de soja, de soro de leite e de leite desnatado em pó (grupo tratamento, num único horário de fornecimento, até 56 dias de vida. Os animais tinham acesso ad libitum à água e ao sal mineral. Suas medidas de peso vivo e altura de ísquio foram tomadas semanalmente. O desenvolvimento em estatura não diferiu entre os tratamentos, e o ganho em peso foi inferior para os animais alimentados com sucedâneo. O menor ganho em peso foi influenciado pelo menor consumo de concentrado e de matéria seca da dieta.
