  1. SRTM Perspective View with Landsat Overlay: San Jose, Costa Rica

    Science.gov (United States)

    2001-01-01

    This perspective view shows the capital city of San Jose, Costa Rica, in the right center of the image (gray area). Rising behind it are the volcanoes Irazu, 3402 meters high (11,161 feet) and Turrialba, 3330 meters high (10,925 feet.)Irazu is the highest volcano in Costa Rica and is located in the Irazu Volcano National Park, established in 1955. There have been at least 23 eruptions of Irazu since 1723, the most recent during 1963 to 1965. This activity sent tephra and secondary mudflows into cultivated areas, caused at least 40 deaths, and destroyed 400 houses and some factories.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 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, South Dakota.Elevation data used in this image was acquired by the Shuttle Radar Topography Mission (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

    1996-01-01

    The ultraviolet global radiation and the global solar radiation at San Jose, Costa Rica (latitude: 9 0 56', longitude: 84 0 54', altitude: 1.172 m.) during the period October 1993 to January 1995 were analyzed with respect to their seasonal variations and their independence. The dependence between the ultraviolet radiation and the clearness index of the skies was also investigated. A poor correlation was found between the quotient of the ultraviolet radiation (Hv/Hg) and between the global solar radiation and the extraterrestrial solar radiation (Hg/Ho). The correlation coefficient found between Hv/Hg and Hg/Ho was not greater than 0.25 for four categories of clearness index, i.e., covered skies, clear skies, and two intermediate conditions. This demonstrates that the ultraviolet radiation is not only associated with other atmospheric transmission conditions. A regression analysis between the hourly values of the ultraviolet and global radiation yielded a linear relationship with a determination coefficient greater than 98%. Thus a simple linear regression is reliable for the estimation of the ultraviolet in San Jose from global solar radiation data. (author) [es

  3. The meaning of nervios: a sociocultural analysis of symptom presentation in San Jose, Costa Rica.

    The foundation of the symbolic tradition in medical anthropology is the examination of a patient's experience of a category of illness. The interpretation of folk explanations of etiology and nosology provides insight into the cultural definition of what constitutes an illness, how and why an illness is labeled, and how the afflicted individual should be treated. Further, the analysis of sociocultural meaning emerges as a critical theoretical contribution to our understanding of health and culture. Allen Young in his article "Some Implications of Medical Beliefs and Practices for Social Anthropology" suggests " that if we want to learn the social meaning of sickness, we must understand that 'signs,' whatever their genesis, become 'symptoms' because they are expressed, elicited, and perceived in socially acquired ways" (1976: 14). He further states that some categories of sickness are particularly interesting in that they enable people to organize the illness event into an episode that has form and meaning (1976: 19-20). Nervios is an example of a symptom that has acquired a special sociocultural pattern of expression, elicitation and perception in San Jose, Costa Rica. The empirical study of symptom presentation in general medicine and psychiatric outpatient clinics describes the patients who present the symptom and their associated attributes and explanations of the symptom's occurrence. The meaning of nervios is then discussed within a social interactional and symbolic framework.

    Full Text Available Se midieron las radiaciones ultravioleta global y solar global en San José, Costa Rica (latitud: 9°56´, longitud: 84°54´, altitud: 1.172m durante el periodo de octubre 1993 a enero 1995 y se analizaron en función de su variación estacional y de la correlación entre ambas. La dependencia entre la radiación ultravioleta y el índice de claridad del cielo también fue investigada, y se encontró una pobre correlación entre el cociente de la radiación ultravioleta y la radiación solar global (Hv/Hg y el índice de claridad. El coeficiente de correlación entre Hv/Hg y Hg/Ho no fue mayor de 0,25 para cuatro categorías de tipos de cielos, i.e., cielos cubiertos, cielos despejados, así como dos ámbitos intermedios, lo que demuestra que la radiación ultravioleta no solamente está asociada con la claridad del cielo, sino también con otras condiciones de transmisión atmosférica. Un análisis de regresión entre los valores horarios de las radiaciones ultravioleta y global mostró una relación lineal con un coeficiente de determinación mayor del 98%. Esta regresión simple es confiable para la estimación de la radiación ultravioleta a partir de datos de radiación global.

    In Costa Rica it is not had studies that have documented heavy the fluvial sediment metal concentrations, caused by point sources of polluting agents, as they are the sites of I deposit of been accustomed to remainders. The potential source of heavy metal concentrations in the study area, it is an active sanitary filling, known like Sanitary Landing Azul River, which is located to the Southeastern of the city of San Jose, in the District of Azul River, Corner of the Union. The site where this made up of a sequence of materials of volcanic origin is located to the filling of Azul River, which could be affected by local fault, this fact would mean a serious threat of contamination of underground waters of the region, then the geological faults constitute very permeable means, able to put in contact the polluting agents of the water-bearing filling with some. The mass of metals deposited in the site, from 1978 to date, metric ton has calculated between 70000 to 100000, which turns it an environmental preoccupation of first order.

    In Costa Rica there are no studies that have documented the concentrations of heavy metals in river sediments, caused by point sources of pollutants, such as the deposits sites of solid waste. The potential source of heavy metals concentrations in the study area, is an active landfill, known as Relleno Sanitario de Rio Azul, which is located southeast of the city of San Jose, in Distrito de Rio Azul de La Union. The site where the landfill Rio Azul is located is composed by a sequence of volcanic materials, which could have been affected by local faulting. This fact would mean a serious threat of contamination of groundwater in the region, geological faults are therefore a highly permeable, able to get in touch the fill pollutants with some aquifer. The mass of metal deposited on the site, from 1978 to date, has been estimated between 70000-100000 tm, which it becomes environmental concern in a first order. The results of X-ray fluorescence show the presence of elements such as vanadium, chromium, magnesium, copper, zinc, rubidium, strontium, potassium, calcium, iron, titanium and yttrium, which show a trend towards more high Concentrates in the fine fraction (d [es

    The levels of particulate matter PM 10 were determined at two sites of San Jose City (Catedral Metropolitana and Junta de Educacion), during a year (September 2005-September 2006), obtaining as annual average 36 ± 8 μg/m 3 and 25 ± 7 μg/m 3 , respectively. Also, the levels of sulfates, nitrates and chlorides were measured for both sites. The annual averages have resulted not to be significantly different for both sites, with a level of significance of 5%. Three of the fourteen sites of measurement of the concentration of nitrogen dioxide in the city, have presented higher values to the recommendation of the World Health Organization, monitoring for one month. The principal component analysis that were applied to the data of this gas, has showed that the variations in the levels are due to large-scale phenomena (meteorological). However, the concentration of sulfate present in the particulate matter has reached higher values to those recorded in cities like Rio de Janeiro and Mexico D.F., product probably of the high sulfur content present in the fuels that are used by the vehicle fleet at Costa Rica. The principal component analysis indicates that has existed a strong correlation between the concentrations of sulfate and nitrate present in the particles PM 10 , pointing the contribution of anthropogenic sources. In the case of chloride, has highlighted the strong existing relationship with the meteorological parameters that were registered during the sampling period. (author) [es

    The objective of the present study, was to elaborate a profile of the contamination by private matter and to characterize the aerosols collected in the Metropolitan Area of San Jose (Costa Rica). For that, a campaign of sampling was carried out in three points of the city of San Jose, differentiated by there degree of activity: Center of San Jose (Central Station of Firemen), San Isidro of Coronado -Canton of Vasquez of Coronado- (Municipality) and Escazu (Municipality). Such campaign was carried out from April 4 to July 4, 1996 (transition summer-winter), and in two periods of time of 8 hours: 8 a.m. to 4 p.m. and of 8 p.m. to 4 a.m. The aerosols were collected utilizing Gent Pm-10 samplers, in filters of polycarbonate of 0,4 μm and 8 μm in cascade, with a flow average of 15 L/min., and it determined the composition average of the present aerosols. The concentration of the majority of the anions were obtained by means of ionic chromatography of high resolution, and the main cations by spectrophotometry of atomic absorption with electro thermic atomization. The space-temporary variations of the concentrations were evaluated and their correlation with the meteorologic variable. (S. Grainger) [es

    Full Text Available Purpose: Bloodstream infections (BSIs are an important cause of mortality in patients with solid tumors. We conducted a retrospective study to evaluate the epidemiologic profile and mortality of patients with solid tumors who have BSIs and were admitted to Mexico Hospital. This is the first study in Costa Rica and Central America describing the current epidemiologic situation. Methods: We analyzed the infectious disease database for BSIs in patients with solid tumors admitted to Mexico Hospital from January 2012 to December 2014. Epidemiology and mortality were obtained according to microorganism, antibiotic sensitivity, tumor type, and presence of central venous catheter (CVC. Descriptive statistics were used. Results: A total of 164 BSIs were recorded, the median age was 58 years, 103 patients (63% were males, and 128 cases of infection (78% were the result of gram-negative bacilli (GNB. Klebsiella pneumoniae (21%, Escherichia coli (21%, and Pseudomonas aeruginosa (15% were the most common microorganisms isolated. Gram-positive cocci (GPC were found in 36 patients, with the most frequent microorganisms being Staphylococcus aureus (10% and Staphyloccocus epidermidis (6%. With respect to tumor type, BSIs were more frequent in the GI tract (57% followed by head and neck (9% and genitourinary tract (8%. Regarding antibiotic susceptibility, only 17% (GNB expressed extended-spectrum beta-lactamase and 12% (GPC had methicillin resistance. Patients with CVCs (n = 59 were colonized mainly by GNB (78%. Overall the mortality rate at 30 days was about 30%. Conclusion: GNB are the most frequent cause of BSIs in solid tumors and in patients with CVCs. GI cancers had more BSIs than other sites. Mortality and antibiotic sensitivity remained stable and acceptable during this observational period in this Latin American population.

    2014-01-01

    An evaluation and analysis are realized of dosimetry of the treatment planning system (TPS) of three-dimensional conformal external radiotherapy in the Servicio de Radioterapia of the Hospital Mexico of Costa Rica. An evaluation procedure is proposed based on IAEA-TECDOC-1540 document, and may continue to be applied periodically in this or other radiotherapy services. Tests realized have checked the representation of distances and electronics densities transferred to the TPS, match with those of real objects. The 16 tests applied have represented situations of real treatments with different configurations and beam modifiers in the equipment used daily. The tests have measured the absorbed dose to water in different significant points at different depths, using photon beams of 6 MeV and 18 MeV. The physical parameters of the tests were simulated. The absorbed dose has been calculated at specified points. The XiO and Eclipse TPS have been used with the calculation algorithms: Superposition, Convolution and AAA. The results of the calculations are evaluated with statistical methods and comparing them with the measurements of absorbed dose. A generalized tendency has been detected toward negative relative errors, implying an underestimation of the dose by the TPS; due to a difference found in the accelerator output factor respect to its commissioning. The AAA algorithm has determined a better performance, although with greater difficulties of calculus in the region of build-up. Convolution and Superposition algorithms have had similar performances and both have presented problems in high depths and out of edges of the fields. The result of the dosimetric evaluation has been satisfactory in real conditions of equipment; but several particularities have been found that should be reviewed and adjusted. The precision of the TPS has been adequate in the majority of situations important for treatment planning. [author] [es

    The San Jose scale Diaspidiotus perniciosus Comstock is one of the most important pests of deciduous fruit trees. The major cause of recent outbreaks in apple orchards is thought to be the development of insecticide resistance, specifically organophosphates. The first report was given in North America, and now, in Chile. In the present study, San Jose scale populations collected from two central regions of Chile were checked for their susceptibility to different mode of action insecticides in order to establish alternatives to manage this pest. No evidence of cross resistance between organophosphates insecticides and acetamiprid, buprofezin, pyriproxyfen, spirotetramat, sulfoxaflor, or thiacloprid was found. Baselines of LC50-LC95 for different life stages of San Jose scale are given, as reference to future studies of resistance monitoring. The systemic activity of acetamiprid, spirotetramat, and thiacloprid was higher than the contact residue effect of these compounds. For sulfoxaflor, both values were similar. Program treatments including one or more of these compounds are compared in efficacy and impact on resistance ratio values. In order to preserve new insecticides as an important tool to control San Jose scale, resistance management programs should be implemented, considering insecticide mode of action classes alternated or mixed. © The Authors 2015.

    2013-01-01

    As a Medical Geology research issue, an environmental arsenic risk assessment study in the most important sedimentary aquifer in southern Uruguay is presented. The Raigon Aquifer System is the most exploited in Uruguay. It has a surface extent of about 1,800 square kilometres and 10,000 inhabitants in San Jose Department, where it was studied. Agriculture and cattle breeding are the main economic activities and this aquifer is the basic support. The groundwater sampling was done on 37 water samples of PRENADER (Natural Resources Management and Irrigation Development Program) wells. Outcropping sediments of Raigon Formation and the overlying Libertad Formation were also sampled in the Kiyu region. The analyses were performed by inductively coupled plasma-optical emission spectrometry (ICP-OES) and inductively coupled plasma-mass spectrometry (ICP-MS). The results showed 80% samples with arsenic levels exceeding the 10 μg/l of WHO as limit for waters, and 11% exceeds the 20 μg/l limit of uruguayan regulation. The median, maximum and minimum water arsenic concentrations determined have been 14.24, 24.19 and 1.44 μg/l, respectively. On the other hand, nine sediment samples of Raigon and Libertad Formations in Kiyu region were analysed and yielded median, maximum and minimum arsenic concentrations of 5.03, 9.82 and 1.18 ppm, respectively. This issue leads to the supposition that the population, as well as industrial and agricultural activities, are consuming water with arsenic concentrations over the national and international maximum recommended limit.

    The San Anselmo School is a one-story brick elementary school building in San Jose, California. The active solar energy system is designed to supply 70% of the space heating and 72% of the cooling load. It is equipped with 3740 square feet of evacuated tube collectors, a 2175-gallon tank for heat storage, a solar-supplied absorption chiller, and four auxiliary gas-fired absorption chillers/heaters. The measured solar fraction of 19% is far below the expected values and is attributed to severe system control and HVAC problems. Other performance data given for the year include the solar savings ratio, conventional fuel savings, system performance factor, and solar system coefficient of performance. Also tabulated are monthly performance data for the overall solar energy system, collector subsystem, space heating and cooling subsystems. Typical hourly operation data for a day are tabulated, including hourly isolation, collector array temperatures (inlet and outlet), and storage fluid temperatures. The solar energy use and percentage of losses are also graphed. (LEW)

    The extreme heat days not only make cities less comfortable for living but also they are associated with increased morbidity and mortality. Mapping studies have demonstrated spatial variability in heat vulnerability. A study conducted between 2000 and 2011 in New York City shows that deaths during heat waves was more likely to occur in black individuals, at home in census tracts which received greater public assistance. This map project intends to portray areas in San Jose California that are vulnerable to extreme heat events. The variables considered to build a vulnerability index are: land surface temperature, vegetated areas (NDVI), and people exposed to these area (population density).

    The San Jose del Guaviare Nepheline Syenite includes two rock bodies that crop out 20 km SW of the town with the same name. The first of these bodies, which had already been reported by Vesga and Castillo (1972), is exposed in the La Pizarra area. The second body, which had not been previously reported, occurs in the Las Delicias area.Petrographic characterization shows that rocks correspond to nepheline syenite, nepheline monzosyenite, and feldspar + nepheline granofels. The main minerals in the rocks are microcline + nepheline + plagioclase + -- biotite + - arfvedsonite, and accessory phases include fluorite, sphene, apatite, garnet, zircon, epidote and calcite. Structures and textures are chiefly igneous in the la Pizarra body and mainly metamorphic (restitic) in the Las Delicias body. The geochemical character of the rocks is alkaline, and they correspond to within- the field of rocks formed in intraplate environment. The above features suggest that the San Jose del Guaviare syenite was formed by anatexis in a continental environment.U/Pb dating of zircon and 40Ar/39Ar (HS) dating of biotite indicates age 577.8+ -/0 6.3 - 9 Ma (Ediacaran) crystallization and 494+ - 5 Ma (late Cambrian) cooling.

    Full Text Available As of 2013, 42 million American households were involved in growing their own food either at home or in a community garden plot. The purpose of this pilot study was to document the extent to which gardeners, particularly less affluent ones, increase their vegetable intake when eating from either home or community garden spaces. Eighty-five community gardeners and 50 home gardeners from San Jose, California, completed a survey providing information on demographic background, self-rated health, vegetable intake and the benefits of gardening. The gardeners surveyed were generally low income and came from a variety of ethnic and educational backgrounds. Participants in this study reported doubling their vegetable intake to a level that met the number of daily servings recommended by the U.S. Dietary Guidelines. Growing food in community and home gardens can contribute to food security by helping provide access to fresh vegetables and increasing consumption of vegetables by gardeners and their families.

    Urban dwellers across the United States increasingly access a variety of fresh vegetables through participation in neighborhood-level community gardens. Here we document vegetable output and cost savings of community gardens in the city of San Jose, CA, to better understand the capacity of community gardens to affect food affordability in an urban setting. A convenience sample of 83 community gardeners in San Jose completed a background survey during spring and summer 2012. On average, gardeners were aged 57 years and had a monthly income of $4,900; 25% had completed college. A representative subset of 10 gardeners was recruited to weigh vegetable output of their plots using portable electronic scales at three separate garden sites. Accuracy of each portable scale was verified by comparing the weight of a sample vegetable to weights obtained using a lab scale precise to 0.2 oz. Garden yields and cost savings were tabulated overall for each plot. Results indicate that community garden practices are more similar to biointensive high-production farming, producing 0.75 lb vegetables/sq ft, rather than conventional agricultural practices, producing 0.60 lb/sq ft. Gardens produced on average 2.55 lb/plant and saved $435 per plot for the season. Results indicate that cost savings are greatest if vertical high value crops such as tomatoes and peppers are grown in community gardens, although yields depend on growing conditions, gardener's skill, availability of water, and other factors. Future research is needed to document cost savings and yields for specific crops grown in community gardens. Copyright © 2014 Academy of Nutrition and Dietetics. Published by Elsevier Inc.

    A study about the concentration levels of some of the main pollutants present in the particule suspended material, with a aerodynamic diameter similar or smaller than 10 μm, was carried out in the air of San Jose's City. For this purpose, a sampling campaign was performed in two points of the capital city: in the buildings of The National Museo de Costa Rica and Ministerio de Seguridad Publica; three times per week (Monday, Wednesday, Friday) during the months of August to December of the year 2002 (rainy season). The in particule material was gathered by two muestreadores of high volume air with a controller of volumetrico flow, on filters of glass fiber (20,3 x 25,4 cm), with an average flow of 1,13 m3/min during 24 hours and the composition of the in particule collected material was determined. The concentration of major anions (sulfate, nitrate, chloride, oxalato ) was obtained by a chromatography of ionic exchange with suppressive of ionization, and the main metals by a spectrophotometry of atomic absorption with electrothermic atomization. The study established that the main anions present in the in particule material are the nitrate and the sulfate, constituting approximately the 2,5% of the weight of the total particulado material. The concentration of such components in both monitoring places overcame the typical values reported by the Agency of Environmental Protection of the United States in some months, probably caused by the high vehicular flow that characterizes to the selected sampling points. t is important to mention that the increment in the precipitation levels during the months of October and November caused a descent in the levels of concentration of in particles material; therefore, in the anions present in the same one. During the quantification of the anions in the particles, the presence of a sign belonging to the oxalato ion was determined; although it was not cuantificable ; it ended to be an interesting discovery. The presence of anions

    The San Jose del Cabo basin at the southern tip of the Baja California peninsula records the early tectonic evolution of the west side of the Gulf of California. This study focused on the east central margin of the basin. The basal La Calera Formation unconformably overlies Cretaceous granite and consists of conglomerate, pebbly sandstone and conglomerate, and sandstone deposited in alluvial fans and fan-deltas. Deposition of the La Calera Formation was from ca. 9-14 Ma. The lower member of the Trinidad Formation was deposited beginning ca. 9-13 Ma and consists of sandstone, mudstone, and shelly mudstone deposited in nearshore and estuarine environments. These age estimates are based on sedimentation rates and foraminifera and coccoliths from the NN 11A nannozone (7.4 8.6 Ma, GTS 2004). The middle member of the Trinidad Formation consists of deeper water mudstones deposited by turbidity currents and suspension settling in a shelf to slope and conglomerates deposited by submarine debris flows on the shelf. The basin began earlier than previously thought. The oldest marine rocks are ca.9-13 Ma, while sedimentation on the east side began at ca. 9-14 Ma, synchronous with estimates of initiation of offset on the San Jose del Cabo fault. The Zapote fault is a down-to-the-east normal and sinistral-oblique fault that exposes a wedge of granite and older strata in the footwall to the west. The fault was active during sedimentation in the late Miocene and possibly later. The fault divides the study area into an eastern hanging wall subbasin and western footwall subbasin. The eastern subbasin formed an embayment in the eastern margin of the Cabo basin. A regional flooding surface (ca. 8 Ma) can be correlated across the fault that marks a major marine incursion. Depositional systems evolved rapidly from coarse-grained terrestrial systems to fine-grained marine and estuarine systems. The Cabo basin provides an excellent analogue for comparison with offshore basins, which are

    We installed a dense array of 41 digital seismographs in San Jose, California, to evaluate in detail the effects of a deep sedimentary basin and shallow sedimentary deposits on earthquake ground motions. This urban array is located near the eastern edge of the Santa Clara Valley and spans the Evergreen sedimentary basin identified by gravity data. Average station spacing is 1 km, with three stations initially spaced 110 m apart. Despite the high-noise urban environment, the stations of the array successfully triggered on and recorded small local earthquakes (M 2.5-2.8 at 10-25 km distance) and larger regional events such as the M 5.0 Bolinas earthquake (90 km distance), M 4.6-5.6 earthquakes near Mammoth Lakes (270 km distance), M 4.9-5.6 events in western Nevada (420 km distance) and the M 7.1 Hector Mine earthquake (590 km distance). Maps of spectral ratios across the array show that the highest amplitudes in all frequency bands studied (0.125-8 Hz) are generally observed at stations farther from the eastern edge of the Santa Clara Valley. Larger spectral amplitudes are often observed above the western edge of the Evergreen Basin. Snapshots of the recorded wavefield crossing the array for regional events to the east reveal that large, low-frequency (0.125-0.5 Hz) arrivals after the S-wave travel from south to north across the array. A moving-window, cross-correlation analysis finds that these later arrivals are surface waves traveling from the south. The timing and propagation direction of these arrivals indicates that they were likely produced by scattering of incident S waves at the border of the Santa Clara Valley to the south of the array. It is remarkable that the largest low-frequency phases at many of the valley sites for regional events to the east are basin surface waves coming from a direction about 70 degrees different from that of the epicenters. Basin surface waves emanating from the eastern edge of the valley are also identified by the cross

    The San Juan Basin, in northwest New Mexico, has vast reserves of strippable, low-sulfur coal. Development of the resource will require large quantities of water, from an area where water resources are not abundant. Since surface-water supplies are fully allocated, increased future water demands will have to be met through ground-water development. The study concentrates on the Ojo Alamo, Nacimiento, and San Jose Formations, the aquifers directly above the principal coal unit. Carbon-14 and tritium methods were used to date the ground water in these units. Initial radiocarbon activities were calculated using the models of Vogel, Tamers, Pearson, Mook and Fontes. The observation lends support to the hypothesis of isotopically lighter Pleistocene precipitation. Such lighter recharge was most likely due to a colder mean annual temperature and perhaps increased winter precipitation. A similar change is obtained from noble-gas paleothermometry

    San José State University was a member of the original ESSEA consortium (2003-05), and it continues its participation with the broadening ESSEA community. Having hosted the original Middle- and High School Teachers' ESSEA courses, the Geology Department and Program in Science Education have maintained their commitments toward supporting pre- and in-service teachers in geoscience concept competency and effective pedagogy. We have witnessed an encouraging trend in the numbers of K-8 (multiple subject) pre-service teachers who have enrolled in our in-house ESSEA-inspired course: Geology 103 (Earth Systems and the Environment). We have also seen an influx of prospective secondary (single subject) teachers seeking credentials in non- geoscience disciplines. California teacher credentialing requirements, especially when layered on the increasing demands of major fields of study and the California State University System's hefty General Education mandates, give prospective teachers little latitude in their academic programs. Geology 103 was developed to satisfy three logistical objectives: to comply with "geoscience content competency" as defined by the California Commission on Teacher Credentialing (CCTC); to fulfill one of the CSU's upper-division General Education requirements, and to develop science process skills in a population that may never have had similar prior opportunities. The course is offered in two modalities: online and on-campus. The Web-based sections are currently comparing the relative effectiveness of two dissimilar online learning modalities and assessments: one delivers video/audio/animated "podcasts," while the other requires student involvement through interactive Flash media. The course is taught by professors with joint appointments in the Department of Geology and Program in Science Education, and by current and former classroom teachers to ensure that geoscience content knowledge is achieved through inquiry, systems analyses, and other

    The solar collector array at the San Anselmo School is located on the roof of the structure, and consists of 3740 square feet of General Electric evacuated tube solar collectors, Model TC-100. Performance of the array during the three-month period was very similar to the overall performance during the previous reporting periods. During the three-month period from April 1982 through June 1982, the solar system at the San Anselmo School performed below expectations despite continued attempts to alleviate several long-standing system problems. Space heating performance appears to be meeting design goals; however, this load was trivial during the three-month period. The retrofitted solar system was designed to provide 70% of the space heating load and 72% of the space cooling load at this 34,000-square-foot brick structure. In all of the previous months of evaluation, the design values of 70% and above have not been achieved for the system as a whole, although one subsystem did achieve high solar contributions during periods of lower building loads, specifically the space heating subsystem. Solar contribution during the three-month period of April 1982 through June 1982 averaged 19% of the total load of 117.4 million Btu, and was, at best, equal to previous performance. Space heating loads were small, and the space cooling load was relatively high over the test period. The solar savings ratio was 14%. The system performance factor is a measure of the equivalent fossil fuel consumption at the site (with operating energy multiplied by 3.33 times to simulate fossil fuel use at the power plant) relative to the actual load, and was 0.15. This value is 0.03 points less than the previous year's value of 0.18. Solar System Coefficient of Performance (COP) increased to 11.0 vs. the previous year's value of 7.6. Apparently, the efficiency of energy transfer in the system has improved, although performance was not really any better.

    Full Text Available Combinar en forma sostenible el patrimonio histórico cultural, el desarrollo turístico y la calidad ambiental es sin duda alguna el reto que enfrentan muchas comunidades latinoamericanas que en años recientes han hecho toda clase de esfuerzos por atraer turistas. 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.

    Full Text Available El presente artículo estudia el fenómeno de las urbanizaciones cerradas en el distrito de San Rafael de Escazú, Costa Rica. La tesis central es que las urbanizaciones cerradas producen cambios en la urbanidad mediante la introducción de transformaciones socio-espaciales manifiestas en la materialidad de las urbanizaciones cerradas, las funciones de estas y el tipo de relaciones sociales que sus residentes mantienen entre sí y con su entorno cercano. El artículo cierra sugiriendo explorar la noción de “urbanidad privada” como una forma de entender la producción de espacio promovida desde los intereses privados expresados en la construcción de conjuntos inmobiliarios cerrados, de los cuales las urbanizaciones cerradas son una de sus manifestaciones más visibles. Los resultados presentados en este ensayo, son producto de la investigación titulada “Urbanizaciones cerradas en Costa Rica: transformaciones socio-espaciales en la urbanidad y segregación socio-residencial en el distrito de San Rafael de Escazú (1990-2012”. This paper examines the phenomenon of gated communities in Costa Rica, specifically in the district of San Rafael, Escazú. The central thesis is that gated communities to changes in urbanity by introducing socio-spatial transformations evident in the materiality of gated communities, the functions of these communities and the type of social relations that its residents have with one another and with their immediate environment. The article suggests exploring the notion of “private urbanity” as a way to understand the production of space promoted by private interests and expressed in the construction of closed real estate developments, most visibly manifested by gated communities..

    Application of GIS and visualization technology significantly contributes to the efficiency and success of developing ground-water models in the Twentynine Palms and San Jose areas, California. Visualizations from GIS and other tools can help to formulate the conceptual model by quickly revealing the basinwide geohydrologic characteristics and changes of a ground-water flow system, and by identifying the most influential components of system dynamics. In addition, 3-D visualizations and animations can help validate the conceptual formulation and the numerical calibration of the model by checking for model-input data errors, revealing cause and effect relationships, and identifying hidden design flaws in model layering and other critical flow components. Two case studies will be presented: The first is a desert basin (near the town of Twentynine Palms) characterized by a fault-controlled ground-water flow system. The second is a coastal basin (Santa Clara Valley including the city of San Jose) characterized by complex, temporally variable flow components ­¦ including artificial recharge through a large system of ponds and stream channels, dynamically changing inter-layer flow from hundreds of multi-aquifer wells, pumping-driven subsidence and recovery, and climatically variable natural recharge. For the Twentynine Palms area, more than 10,000 historical ground-water level and water-quality measurements were retrieved from the USGS databases. The combined use of GIS and visualization tools allowed these data to be swiftly organized and interpreted, and depicted by water-level and water-quality maps with a variety of themes for different uses. Overlaying and cross-correlating these maps with other hydrological, geological, geophysical, and geochemical data not only helped to quickly identify the major geohydrologic characteristics controlling the natural variation of hydraulic head in space, such as faults, basin-bottom altitude, and aquifer stratigraphies, but also

    Bystander cardiopulmonary resuscitation (CPR) improves survival after prehospital cardiac arrest. While community CPR training programs have been implemented across the US, little is known about their acceptability in non-US Latino populations. The purpose of this study was to identify barriers to enrolling in CPR training classes and performing CPR in San José, Costa Rica. After consulting 10 San José residents, a survey was created, pilot-tested, and distributed to a convenience sample of community members in public gathering places in San José. Questions included demographics, CPR knowledge and beliefs, prior CPR training, having a family member with heart disease, and prior witnessing of a cardiac arrest. Questions also addressed barriers to enrolling in CPR classes (cost/competing priorities). The analysis focused on two main outcomes: likelihood of registering for a CPR class and willingness to perform CPR on an adult stranger. Odds ratios and 95% CIs were calculated to test for associations between patient characteristics and these outcomes. Among 371 participants, most were male (60%) and education (OR: 1.9; 95% CI, 1.1-3.2). Believing that CPR does not work was associated with a higher likelihood of not attending a CPR class (OR: 2.4; 95% CI, 1.7-7.9). Fear of performing mouth-mouth, believing CPR is against God's will, and fear of legal risk were associated with a likelihood of not attending a CPR class and not performing CPR on a stranger (range of ORs: 2.4-3.9). Most San José residents are willing to take CPR classes and perform CPR on a stranger. To implement a community CPR program, barriers must be considered, including misgivings about CPR efficacy and legal risk. Hands-only CPR programs may alleviate hesitancy to perform mouth-to-mouth.

    2007-01-01

    An organized oral session at the annual meeting of the Ecological Society of America in San Jose, Calif., posed this question: Is climate-induced drought stress triggering increasing rates and unusual patterns of forest die-off at a global scale? Twenty-nine researchers representing five continents reported on patterns, mechanisms, and projections of forest mortality.Observations include widespread forest dieback or reductions in tree cover and biodiversity in response to drought and warmer temperatures in the African Sahel (Patrick Gonzalez, The Nature Conservancy), Mediterranean and alpine Europe (Jorge Castro, Universidad de Granada), and Argentinean Patagonia (Thomas Kitzberger, Universidad Nacional del Comahue). In contrast, although much Eucalyptus mortality has resulted from recent droughts in Australia, warming trends have been less pronounced in the Southern Hemisphere and it is unclear if contemporary climate-induced tree mortality differs from previous historical drought impacts (Rod Fensham, Queensland Herbarium).

    In the last years, there has been an increase in the production, industrialization and consumption of goat's milk and derivate products, including cheese, worldwide. Nevertheless, in Costa Rica there is no study of these products, reason why the objective of this work was to determine the microbiological characteristics of goat's milk and fresh cheese distributed in the Metropolitan Area of San José, Costa Rica, in order to evaluate its impact in the economical field and as a potential risk for Public Health. A total of 25 raw goat's milk samples, obtained by manual milking from 5 different producers tested in five different dates and 15 cheese samples, elaborated with pasteurized milk, commercially available and coming from three different producers were analyzed. The study included the analysis of spoilage bacteria (total aeobic count and lactic bacteria count), indicators of hygiene (total coliforms), fecal contamination (fecal coliforms), manipulation (Staphylococcus aureus) and pathogens (Listeria monocytogenes and Salmonella spp). High results were obtained for the total aerobic count and lactic bacteria count of the milk and cheese samples, showing a reduced shelf life. Total coliforms, in limits beyond the established ones by the Costa Rican legislation for human consumption raw milk, were found in 100% of milk samples, as well as for fecal coliforms in 76% of them. All cheese samples, except one, were negative for these indicators, suggesting good manufacturing practices. S. aureus counts were low and both Salmonella spp. and L. monocytogenes were not isolated from samples analyzed.

    Maps showing the probability of surface manifestations of liquefaction in the northern Santa Clara Valley were prepared with liquefaction probability curves. The area includes the communities of San Jose, Campbell, Cupertino, Los Altos, Los Gatos Milpitas, Mountain View, Palo Alto, Santa Clara, Saratoga, and Sunnyvale. The probability curves were based on complementary cumulative frequency distributions of the liquefaction potential index (LPI) for surficial geologic units in the study area. LPI values were computed with extensive cone penetration test soundings. Maps were developed for three earthquake scenarios, an M7.8 on the San Andreas Fault comparable to the 1906 event, an M6.7 on the Hayward Fault comparable to the 1868 event, and an M6.9 on the Calaveras Fault. Ground motions were estimated with the Boore and Atkinson (2008) attenuation relation. Liquefaction is predicted for all three events in young Holocene levee deposits along the major creeks. Liquefaction probabilities are highest for the M7.8 earthquake, ranging from 0.33 to 0.37 if a 1.5-m deep water table is assumed, and 0.10 to 0.14 if a 5-m deep water table is assumed. Liquefaction probabilities of the other surficial geologic units are less than 0.05. Probabilities for the scenario earthquakes are generally consistent with observations during historical earthquakes.

    We present an inventory of the amphibians and reptiles of the San Vito de Coto Brus region, including the Las Cruces Biological Station, in southern Costa Rica, which is the result of a survey of the herpetofauna occurring in mountain forest fragments, pastures, coffee plantations, and other disturbed areas. We found 67 species, included 26 species of amphibians and of 41 of reptiles. We describe the distribution patterns of the community on the basis of the life zones, elevation, fragmentation, and degree of anthropogenic impact. We also provide some nouvelle data on the systematics of some select taxa, their geographical ranges, microhabitats, activity, and other relevant ecological and natural history features. Finally, we comment on the present conservation status of the herpetofauna in the region. Previous literature and collection records indicate a higher number of species occurring in this area, which suggests that some declines have occurred, especially of amphibians, in last decades.

The highest infection rates have been detected in parrots (Psittacidae and pigeons (Columbiformes, the latter most frequently carry the genotypes B and E. These genotypes have been shown to also infect humans. Because pigeons (Columba livia cohabit with humans in urban areas, C. psittaci present in the dust from dry feces of infected pigeons may be transmitted by inhalation and represent a significant public health problem. Between 2012 and 2013 a total of 120 fecal samples were collected from pigeons at four public places (Plaza de la Cultura, Parque Morazán, Parque Central de Guadalupe, Plaza de las Garantías Sociales in San José, Costa Rica. A nested polymerase chain reaction (PCR was used to amplify a region of the outer membrane protein A gene of C. psittaci. Only one sample was positive in PCR and the positive sample was further subjected to sequencing and genotyping. Sequencing identified this sample as C. psittaci genotype B. This study is the first report to show the presence of this organism in pigeons of Costa Rica, and shows that the infected pigeons may represent a significant risk for humans who visit public places that are inhabited by pigeons.

    Alameda County is located at the northern end of the Diablo Range of Central California. It is bounded on the north by the south flank of Mount Diablo, one of the highest peaks in the Bay Area, reaching an elevation of 1173 meters (3,849 ft). San Francisco Bay forms the western boundary, the San Joaquin Valley borders it on the east and an arbitrary line from the Bay into the Diablo Range forms the southern boundary. Alameda is one of the nine Bay Area counties tributary to San Francisco Bay. Most of the country is mountainous with steep rugged topography. Alameda County is covered by twenty-eight 7.5' topographic Quadrangles which are shown on the index map. The Quaternary deposits in Alameda County comprise three distinct depositional environments. One, forming a transgressive sequence of alluvial fan and fan-delta facies, is mapped in the western one-third of the county. The second, forming only alluvial fan facies, is mapped in the Livermore Valley and San Joaquin Valley in the eastern part of the county. The third, forming a combination of Eolian dune and estuarine facies, is restricted to the Alameda Island area in the northwestern corner of the county.

    Alvarado, Guillermo E.; Brenes, Jorge; Brenes, Jose

    2013-01-01

    In Costa Rica, small fragments of amber are found in the Miocene shallow marine clastic sedimentary rocks, such as Formacion Punta Judas (Middle Miocene), Formacion Santa Teresa (Middle Miocene), and Formacion Curre (Middle-Upper Miocene). Sub-amber or copal is found in relative abundance in certain localities in the residual soils in the mountains near San Cristobal de Savegre (Aguirre, Puntarenas). The copal samples have sub-rounded or pearly (21.3%), tabular or laminar (29.6%) and troncoidal (30.4%) forms, but some are intermediate or indefinite (18.7%). Its color varies between orange / red (57.4%), followed by yellow (31.0%) and less frequently light yellow to whitish (11.6%); some samples have insects incorporated. The age of the copal is in the age range of 1670-1780 A.D., based on a calibrated 14 C dating. Although these samples of copal seem to have no commercial value, they could be used by local artisans.

    The use of Solid State Nuclear Track detectors (SSNTD), LR-115 type II-Quick, is one of the convenient technique to assess the average radiation levels of alpha activities in the environment. This technique has been used to assess the Radon concentration in some areas of San Jose, Costa Rica. Exposed SSNTD films are chemically etched in an alkaline solution and the density of alpha tracks are given as concentration (pCi/L) of Radon. The only known health effect associated with exposure to elevated levels of Radon is an increased risk of developing lung cancer. (authors). 10 refs, 4 figs, 3 tabs

    During 2003, the Jose Cabrera nuclear power plant (JCNPP) operated without any incidents involving an undue risk to the population or environment. The year 2003 was the Plant's 35th year of operation, and during that time it has provided 33.209 million kilowatt-hours to the electric grid. The Plant set a record for continuous operation with 386 days of uninterrupted operation. The Plant had an outage for the 27th refueling and for equipment and systems maintenance, inspection and testing activities. The Plant reported nine events to the Administration that were classified as zero on the International Nuclear Event Scale (INES) and another event classified as level 1. AENOR performance the audit for renewing certificate UNE-EN ISO-9001, and for tracking environmental management systems as per UNE-EN ISO 14001, with satisfactory results. The dose around the Plant caused by plant operation has been insignificant. For the first time in the Spanish industry, the Plant has implemented an integrated safety system that encompasses all the plant's safety-related activities.

Two profiles AA' (Turbo - San Jose del Guaviare and BB' (Quibdo - Puerto Berrio, analyzed corroborate the existence of two zones, one with oceanic crustal (West of Romeral and other with continental crustal (to the East; among both profiles there is a point of inflexion in the direction of the attitude of Romeral fault, from which they present important changes in the accretion components and efforts, giving origin to important variations in the model of subduction. To the North of the point of inflexion two zones of subduction appear, the current one associated with the Sinu fault and a fossil were area associated to the with Romeral's fault. Besides, locally they find evidences so much in surface geology as gravimetry of a obduction zone. To the south of this point theree subduction zones were determined, the current one associated to the Pacific grave and two fossilized associated to the sutures or Romeral's faults and of the Atrato river fault's. In the profile AA', in the zone of continental crust are observed the sectors of Cordillera Central, Cordillera Oriental and Llanos Orientales. In the profile BB ' is appreciated until the Valle Medio del Magdalena. The differences among these areas they reside in the type of rock of the basement and the deformation style.

    During 2003, the Jose Cabrera nuclear power plant (JCNPP) operated without any incidents involving an undue risk to the population or environment. The year 2003 was the Plant's 35th year of operation, and during that time it has provided 33.209 million kilowatt-hours to the electric grid. The Plant set a record for continuous operation with 386 days of uninterrupted operation. The Plant had an outage for the 27th refueling and for equipment and systems maintenance, inspection and testing activities. The Plant reported nine events to the Administration that were classified as zero on the International Nuclear Event Scale (INES) and another event classified as level 1. AENOR performance the audit for renewing certificate UNE-EN ISO-9001, and for tracking environmental management systems as per UNE-EN ISO 14001, with satisfactory results. The dose around the Plant caused by plant operation has been insignificant. For the first time in the Spanish industry, the Plant has implemented an integrated safety system that encompasses all the plant's safety-related activities

  5. Rescue for sexually abused girls in Costa Rica.

    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.

  6. Blind comparisons of shear-wave velocities at closely-spaced sites in San Jose, California: Proceedings of a Workshop held at the US Geological Survey, Menlo Park, May 3, 2004

    Shear-wave velocities within several hundred meters of Earth's surface are important in specifying earthquake ground motions for engineering design. Not only are the shearwave velocities used in classifying sites for use of modern building codes, but they are also used in site-specific studies of particularly significant structures. Many are the methods for estimating sub-surface shear-wave velocities, but few are the blind comparisons of a number of the methods at a single site. The word "blind" is important here and means that the measurements and interpretations are done completely independent of one another. Stephen Hartzell of the USGS office on Golden, Colorado realized that such an experiment would be very useful for assessing the strengths and weaknesses of the various methods, and he and Jack Boatwright of the USGS office in Menlo Park, California, in cooperation with Carl Wentworth of the Menlo Park USGS office found a convenient site in the city of San Jose, California. The site had good access and space for conducting experiments, and a borehole drilled to several hundred meters by the Santa Clara Valley Water District was made available for downhole logging. Jack Boatwright asked David Boore to coordinate the experiment. In turn, David Boore persuaded several teams to make measurements, helped with the local logistics, collected the results, and organized and conducted an International Workshop in May, 2004. At this meeting the participants in the experiment gathered in Menlo Park to describe their measurements and interpretations, and to see the results of the comparisons of the various methods for the first time. This Open-File Report describes the results of that workshop. One of the participants, Michael Asten, offered to help the coordinator prepare this report. Because of his lead role in pulling the report together, Dr. Asten is the lead author of the paper to follow and is also the lead Compiler for the Open-File Report.It is important to

    Elevations of 49 bench marks in the southwestern part of the Sacramento-San Joaquin River Delta were determined during October and November 1987. A total of 58 miles of level lines were run in the vicinity of Bethel Island and the community of Discovery Bay. The datum of these surveys is based on a National Geodetic Survey bench mark T934 situated on bedrock 10.5 mi east of Mount Diablo and near Marsh Creek Reservoir. The accuracy of these levels, based on National Geodetic Survey standards, was of first, second, and third order, depending on the various segments surveyed. Several bench marks were noted as possibly being stable, but most show evidence of instability. (USGS)

  18. Air pollution in a tropical city: the relationship between wind direction and lichen bio-indicators in San José, Costa Rica

    Full Text Available Lichens are good bio-indicators of air pollution, but in most tropical countries there are few studies on the subject; however, in the city of San José, Costa Rica, the relationship between air pollution and lichens has been studied for decades. In this article we evaluate the hypothesis that air pollution is lower where the wind enters the urban area (Northeast and higher where it exits San José (Southwest. We identified the urban parks with a minimum area of approximately 5 000m² and randomly selected a sample of 40 parks located along the passage of wind through the city. To measure lichen coverage, we applied a previously validated 10 x 20cm template with 50 random points to five trees per park (1.5m above ground, to the side with most lichens. Our results (years 2008 and 2009 fully agree with the generally accepted view that lichens reflect air pollution carried by circulating air masses. The practical implication is that the air enters the city relatively clean by the semi-rural and economically middle class area of Coronado, and leaves through the developed neighborhoods of Escazú and Santa Ana with a significant amount of pollutants. In the dry season, the live lichen coverage of this tropical city was lower than in the May to December rainy season, a pattern that contrasts with temperate habitats; but regardless of the season, pollution follows the pattern of wind movement through the city.

    1986-01-01

    Jose Cabrera (Zorita) tube examination procedures are discussed. This plant continues to use phosphate water chemistry (sodium/phosphate ratio = 2.1). Three hot leg tube segments were pulled from the Jose Cabera (Zorita) plant in 1985. One tube had a field EC indication on the OD at the first tube support plate and the other two had field EC indications on their ID about 3 inches above the bottom of the tube sheet. All three tubes were initially sent to Battelle for preliminary NDE and decontamination. Segments of two tubes were sent to Westinghouse for destructive examination. The results of the laboratory eddy current and radiographic examinations are given. The results of the visual examinations are also given. The tube with OD indications was destructively examined and shallow intergranular pitting and intergranular attack, up to 2 mils deep, were found on the OD in the tube sheet region. Local areas of IGA, up to 5 mils deep, were found on the OD within the tube support plate region. A summary of this information together with supporting micrographs is given. It was hypothesized that a caustic crevice environment was the cause of this mild degradation. Shallow areas of thinning or wastage, up to 3 mils, were found just above the top of the tube sheet in the sludge pile region. Even more shallow wastage was found at the edges of support plate locations. This wastage is believed to be the remnant of early plant chemistry when a higher sodium/phosphate ratio and higher phosphate concentration were allowed

    The Turrialba Volcano near San Jose, Costa Rica regularly emits plumes containing SO2. These plumes have been detected by the Ozone Monitoring Instrument (OMI), and evidence of these plumes has also appeared in the in-situ Ticosonde project record: a continuous balloon-borne ozonesonde launch experiment conducted in a weekly basis in Costa Rica. In the case of the latter, the interference reaction of SO2 in the cathode cell of the standard electrochemical concentration cell (ECC) ozonesonde results in apparent "notches" in the ozone profile at the altitudes of the plume. In this paper, we present an overview of the Ticosonde observations and correlate the appearance of the notches with air mass back trajectory calculations that link the profiles features to emissions from the volcano. In addition, during February 2012, we deployed the dual O3/SO2 sonde from the University of Costa Rica and detected a plume of SO2 linked by back trajectory calcluations to Turrialba as well as an urban plume resulting from diesel exhaust in the boundary layer. The integrated column SO2 from the sonde profile data agree well with the OMI overpass data for this event. Data from a tethersonde measurement two days prior to the dual sonde reveal concentrations at the ppm level at the volcanic source.

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

    To prepare a common acting plan with respect to Severe Accident Management, in 1994 was founded the severe accident management ''ad-hoc'' working group from the Spanish Westinghouse PWR Nuclear Power Plant Owners Group. In this group actively collaborated the Jose Cabrera NPP Training Centre and the Department of Nuclear Engineering of UNION FENOSA. From this moment, Jose Cabrera NPP began the planning of its specific Severe Accident Management Program, which main point are Severe Accident Management Guidelines (SAMG). To elaborate this guidelines, the Spanish translation of Westinghouse Owners Group (WOG) Severe Accident Management Guidelines were considered the reference documents. The implementation of this Guidelines to Jose Cabrera NPP started on January 1997. Once the specific guidelines have been implemented to the plant, training activities for the personnel involved in severe accident issues will be developed. To prepare the training exercises MAAP4 code will be used, and with this intention, a specific Jose Cabrera NPP MAAP-GRAAPH screen has been developed. Furthermore, a wide selection of MAAP input files for the simulation of different scenarios and accidental events is available. (Author)

    Accessions of two wild species blueberry from Costa Rica were characterized for use in the genetic improvement of this crop. A collection of accessions of two wild species blueberry (Vaccinium consanguineum and V. poasanum) were georeferenced and collected in the highlands of the provinces of Alajuela, San Jose and Cartago. The bushes collected were transplanted in the subestacion Fraijanes of the Estacion Experimental Fabio Baudrit Moreno of the Universidad de Costa Rica. Quantitative and qualitative descriptors were evaluated to morphologically characterize in situ and ex situ the accessions collected from each of the two species. The effect of two antimitotic agents, colchicine and oryzalin was determined on the chromosomal duplication of accessions of V. consanguineum and V. poasanum established in vitro. The gibberellic acid was used to promote in vitro germination of the seeds of V. consanguineum and V. poasanum, but reduces the percentage of germination in the latter species if it is used in high doses. The effect of antimitotic agents on the ploidy of both species was determined by flow cytometry [es

Los actuales usos que le son otorgados, considerando una franja de unos 5 km, están vinculados con actividades productivas y recreativas. En este trabajo interesa analizar las actividades recreativas que se desarrollan fuera de circuitos turísticos convencionales y que son realizadas tanto por los pobladores locales como a partir de la afluencia estacional de visitantes, puesto que sus desempeños podrían introducir disturbaciones en el registro arqueológico costero existente. En primera instancia, se prevé que el acceso esporádico al litoral marino podría producir daños, los cuales puede provenir de la apertura de huellas, a través de las cuales acceder a la playa, y de la acumulación de desperdicios. Entre los descartes modernos revisten un especial interés las acumulaciones de valvas actuales, producidas por el marisqueo de moluscos recolectados durante las visitas, puesto que esta clase de residuos generan pequeños concheros. En consecuencia, nuestro objetivo es reconocer los sectores de la costa que son utilizados con fines recreativos de forma espontánea y realizar un análisis comparativo de las estructuras de descarte generadas en el pasado (concheros y las recientemente (basurales, para proponer criterios que permitan diferenciarlas. Se prevé que los resultados obtenidos permitirán reconocer qué sectores del litoral marino son los que se encuentran afectados, los conflictos que se producen en el uso de este espacio en relación con el registro arqueológico y ofrecer recomendaciones dirigidas a un turismo sustentable.

    This paper presents the results obtained during the development and implementation of the Jose Cabrera NPP Lifetime Management Program according to the methodology applied in the Plant. The implementation of the Lifetime Management Program began in 1995 with the elaboration of the annual revision document 'Lifetime Management Plan', which describes the level of development of the Lifetime Management activities, the results that have been obtained during the implementation of the Program, and the schedule of the upcoming activities. The drawing up of a weighted list of 135 important components and the elaboration of 17 dossiers integrating the ageing mechanisms analysis and its corresponding evaluation, control and mitigation methods, were the result of the activities completed during 1996. A group of 62 component/degradation phenomena pairs with a high degradation risk classification has been considered within the scope of the activity 'Assessment of Maintenance Practices. Improvement Proposal', performed by the plant during 1997 and the first term of 1998 in parallel with other Lifetime Management related activities. The results obtained within this activity have revealed for the components included in the scope of the assessment that the associated degradation phenomena are practically covered by the current maintenance, inspection and testing practices. Recommendations and improvements of the maintenance practices have been particularly proposed from a technical, supporting, proceeding and documentary point of view, and currently an analysis is being made in relation to the feasibility of implementing them at the Jose Cabrera NPP.

    The effect of two organic fertilizers on soil chemical properties and plant performance blackberry (Rubus adenotrichus cv.Vino) in two areas of Costa Rica were evaluated. For this purpose, two experiments were established, one in Buena Vista of Perez Zeledon (BVPZ) and another in San Martin of Leon Cortes (SMLC), both in the province of San Jose, Costa Rica. The research was conducted between August 2005 and July 2008. Three treatments were evaluated in each experiment: Compost (C) and Vermicompost (L), at the rate of 4 kg/plant and 3 kg/plant respectively, and a control without fertilizer (T). The frequency of application of fertilizer at planting was given at 6, 12, 18 and 24 months for a total of 6,6 t/ha for C and 4,9 t/ha for L. Soil samples were taken at 0, 6, 12, 18, 24 and 35 months, after planting for analysis. The results have shown that in both agro-ecosystems, the application of C and L has increased soil pH, reduced acidity, has increased the availability of Ca, Mg, K, N, and P, and has favored the effective cation exchange capacity (ICC) and the percentage of organic matter. The accumulation of Mn, Cu and Zn was not observed. Performance-wise, in BVPZ only significant have found differences (P = 0,00188) between C (1,8 t/ha) and T (0,9 t/ha), while in SMLC, found no differences statistical significant (P [es

    The burden of cardiovascular disease is growing in the Mesoamerican region. Patients' disease self-management is an important contributor to control of cardiovascular disease. Few studies have explored factors that facilitate and inhibit disease self-management in patients with type 2 diabetes and hypertension in urban settings in the region. This article presents patients' perceptions of barriers and facilitating factors to disease self-management, and offers considerations for health care professionals in how to support them. In 2011, 12 focus groups were conducted with a total of 70 adults with type 2 diabetes and/or hypertension who attended urban public health centers in San José, Costa Rica and Tuxtla Gutiérrez, Chiapas, Mexico. Focus group discussions were transcribed and coded using a content analysis approach to identify themes. Themes were organized using the trans-theoretical model, and other themes that transcend the individual level were also considered. Patients were at different stages in their readiness-to-change, and barriers and facilitating factors are presented for each stage. Barriers to disease self-management included: not accepting the disease, lack of information about symptoms, vertical communication between providers and patients, difficulty negotiating work and health care commitments, perception of healthy food as expensive or not filling, difficulty adhering to treatment and weight loss plans, additional health complications, and health care becoming monotonous. Factors facilitating disease self-management included: a family member's positive experience, sense of urgency, accessible health care services and guidance from providers, inclusive communication, and family and community support.Financial difficulty, gender roles, differences by disease type, faith, and implications for families and their support were identified as cross-cutting themes that may add an additional layer of complexity to disease management at any stage.

    Large-scale measurements of ozone and aerosol distributions were made from the NASA DC-8 aircraft during the TC4 (Tropical Composition, Cloud, and Climate Coupling) field experiment conducted from June 28 - August 10, 2007 based in San Jose, Costa Rica. Remote measurements were made with an airborne lidar to provide ozone and multiple-wavelength aerosol and cloud backscatter profiles from near the surface to above the tropopause along the flight track. Aerosol depolarization measurements were also made for the detection of nonspherical aerosols, such as mineral dust, biomass burning, and recent emissions from South American volcanoes. Long-range transport of Saharan dust with depolarizing aerosols was frequently observed in the lower troposphere both over the Caribbean Sea and Pacific Ocean and within the marine boundary layer. In addition, visible and sub-visible cirrus clouds were observed with the multi-wavelength backscatter and depolarization measurements. Initial distributions of ozone, aerosol, and cloud are presented which will be used to interpret large-scale atmospheric processes. In situ measurements of ozone and aerosols made onboard the DC-8 will be compared to the remote lidar measurements. This paper provides a first look at the characteristics of ozone, aerosol, and cloud distributions that were encountered during this field experiment and provide a unique dataset that will be further related through satellite data, backward trajectories, and chemical transport models (CTM) to sources and sinks of ozone, aerosols, and clouds and to dynamical, chemical, and radiative processes.

    Globally volcanic activity results in huge human, social, environmental and economic losses. Disaster risk reduction (DRR) is the concept and systematic practice of reducing disaster risks and associated losses through a wide range of strategies, including efforts to increase knowledge through education and outreach. However, recent studies have shown a substantial gap between risk reduction actions taken at national and local levels, with national policies showing little change at the community level. Yet it is at local levels are where DRR efforts can have the biggest impact. This research focuses on communicating hazard preparedness strategies at Turrialba volcano, Costa Rica. Located in the Central Cordillera just 35 km northeast of Costa Rica's capital city San Jose this 3,340 m high active stratovolcano looms over Costa Rica's Central Valley, the social and economic hub of the country. Following progressive increases in degassing and seismic activity Turrialba resumed activity in 1996 after more than 100 years of quiescence. Since 2007 it has continuously emitted gas and since 2010 intermittent phreatic explosions accompanied by ash emissions have occurred. Despite high levels of hazard salience individuals and communities are not or under-prepared to deal with a volcanic eruption. In light of Turrialba's continued activity engaging local communities with disaster risk management is key. At the local levels culture (collective behaviours, interactions, cognitive constructs, and affective understanding) is an important factor in shaping peoples' views, understanding and response to natural phenomena. As such an increasing number of academic studies and intergovernmental organisations advocate for the incorporation of cultural context into disaster risk reduction strategies, which firstly requires documenting people's perception. Therefore approaching community disaster preparedness from a user-centred perspective, through an iterative and collaborative

    The Jose Cabrera Nuclear Power Plant (NPP) was the first commercial power reactor (Westinghouse 1 loop PWR 510 MWth, 160 MWe) commissioned in Spain and provided the base for future development and training. The reactor construction started in 1963 and it was officially on-line by 1969. The NPP operated from 1969 until 2006 when it became the first reactor to be shut down after completing its operational period. The containment is reinforced concrete with a stainless steel head. In 2010 responsibility for D and D was transferred to Enresa to achieve IAEA level 3 (a green field site available for unrestricted re-uses) by 2017. Of the total of more than 104,000 tons of materials that will be generated during dismantling, it is estimated that only ∼4,000 tons will be radioactive waste, some of which, 40 t are considered as intermediate level long-lived wastes and the rest (3,960 t) will be categorized as VLLW and ILLW.

    Full Text Available Contexto: El riesgo de embarazo no deseado está presente en mujeres que tienen relaciones sexuales sin protección.. Esa situación se dio en 70% de las costarricenses entrevistadas en 1999 por la Encuesta Nacional de Salud Reproductiva (ENSR, quienes declararon no haber usado anticonceptivos en su primer encuentro sexual. El mismo riesgo ocurre entre las adolescentes entre 13 y 17 años, sexualmente activas; la mitad de ellas no usa anticoncepción. Esto es consistente con el hecho que 42% de las costarricenses con hijos, entrevistadas por ENSR, no desearon su último embarazo. A ello se agrega que algunos embarazos no deseados terminan en aborto provocado, con el consiguiente riesgo de muerte materna. El objetivo del presente estudio es evaluar los conocimientos, actitudes y prácticas de los gineco-obstetras acerca de la AE, en el marco de la atención integral de la mujer que está en riesgo de embarazo no deseado por haber tenido relaciones sexuales sin protección.Métodos: Se aplicó un cuestionario estructurado de 20 preguntas a 60 gineco-obstetras del área metropolitana de San José para indagar sus conocimientos, actitudes y prácticas en relación con AE.Resultados: El 92% había escuchado sobre AE, 80% conocía las indicaciones y 82% los efectos secundarios.

    Full Text Available Contexto: El riesgo de embarazo no deseado está presente en mujeres que tienen relaciones sexuales sin protección.. Esa situación se dio en 70% de las costarricenses entrevistadas en 1999 por la Encuesta Nacional de Salud Reproductiva (ENSR, quienes declararon no haber usado anticonceptivos en su primer encuentro sexual. El mismo riesgo ocurre entre las adolescentes entre 13 y 17 años, sexualmente activas; la mitad de ellas no usa anticoncepción. Esto es consistente con el hecho que 42% de las costarricenses con hijos, entrevistadas por ENSR, no desearon su último embarazo. A ello se agrega que algunos embarazos no deseados terminan en aborto provocado, con el consiguiente riesgo de muerte materna. El objetivo del presente estudio es evaluar los conocimientos, actitudes y prácticas de los gineco-obstetras acerca de la AE, en el marco de la atención integral de la mujer que está en riesgo de embarazo no deseado por haber tenido relaciones sexuales sin protección. Métodos: Se aplicó un cuestionario estructurado de 20 preguntas a 60 ginecoobstetras del área metropolitana de San José para indagar sus conocimientos, actitudes y prácticas en relación con AE. Resultados: El 92% había escuchado sobre AE, 80% conocía las indicaciones y 82% los efectos secundarios. El 48% la había prescrito alguna vez. Sobre el mecanismo de acción, 10% respondió correctamente que impide la ovulación o la fecundación (13%. Entre las respuestas erróneas, uno de cada cuatro respondió que actúa produciendo aborto y 44% que impide la implantación. Sólo la mitad de los entrevistados sabía cómo se usa. En cuanto a la eficacia, el 75% respondió que el porcentaje de éxito en evitar un embarazo es alto. Se prescribió con más frecuencia en casos de violación o incesto, en pequeño porcentaje en casos de relaciones sexuales no protegidas.

    Full Text Available The study aims at emphasizing the strong presence of the renowned Patriarch of Independence Jose Bonifacio de Andrada e Silva in discussions on environmental degradation that occurred in Brazil in the nineteenth century. The author registered his concern about deforestation in the Brazilian rainforests for farming and charcoal production, and warned about the depletion of water resources, as well as the disappearance of important trees – important raw-material for the shipbuilding industry. He proposed replanting seedlings, the rational use of natural resources, and recommended the adoption of agricultural practices only in valleys. These proposals show an aspect of Bonifacio that is unknown to Brazilian historiography.

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

    Turrialba is an active stratovolcano located in the Central Cordillera of Costa Rica with an elevation of 3,340 m. Located just 35 km northeast of Costa Rica's capital city San Jose it looms over Costa Rica's Central Valley, the social and economic hub of the country. After more than 100 years of quiescence Turrialba resumed activity in 1996, marked by progressive increases in degassing and seismic activity with gas emissions becoming continuous in 2007. Intermittent phreatic explosions accompanied by ash emissions that have reached the capital have been occurring since 2010. The activity has resulted in the evacuation of two villages, closure of the National Park that comprises the summit region of the volcano and devastation of the local ecosystem. In this work we present a multi-disciplinary and multi-sensor assessment of the persistent degassing and its impacts on the local ecosystem. Combining a variety of high temporal and high spatial resolution satellite-based time series with ground-based measurements of ambient gas concentrations, element deposition and surveys of species richness, enables a comprehensive assessment of SO2 emissions and changes in vegetation. Satellite-based time-series were obtained from Landsat TM and ETM+, Terra ASTER and MODIS, Aqua MODIS, EO-1 and Aura OMI, with some of the data dating back to 2000. Preliminary results show exposure to the volcanic plume results in high soil acidity and significant uptake of certain heavy metals (e.g. Cd, Co, Cu, Hg and Pb) by vegetation, in contrast other elements such as Ba, Ca and Sr are leached from the soil as a result of the acid deposition. These factors are likely to be responsible for decreased species richness and physiological damage observed downwind of Turrialba. Ambient SO2 concentrations that exceed WHO guideline values have been recorded, which has potentially important consequences for human health in the area.

    The environmental pollution because of heavy metals (HM) in soils is a concern for the agricultural production, due to the adverse effects that it causes in the quality of the cultivation. Numerous countries have been able to establish values of reference on the content of HM in soils. Cuba does not have this information, what means a potential risk for the quality of food production of vegetable origin and a danger for alimentary security. The objective of this work was to determine the available content of HM (extracted with E.D.T.A. 0, 0200 mol.L -1) in soils with low anthropic activity. Determinations of texture by means of Bouyoucos method, pH in water and in KCl by potentiometric, contents of sodium and potassium by flame photometric, calcium and magnesium contents by complex formation volumetric, total organic carbon content by means of the colorimetric method and the available contents of Cadmium, Copper, Iron, Nickel and Lead for the Spectrometric of Atomic Absorption, were made to three types of ferralitic soils, with a total of fifteen replicas for each of them. The obtained results indicated that the soils presented low capacity of cationic exchange and prevalence of clay fraction. Except for the Cadmium, the cationic presented inferior values to those internationally reported as permissible maxima. The information obtained provided necessary elements for the best soil management and their usage in the future. It will also contribute to establish reference indicators for these types of soils in Cuba

    The Jose Cabrera (Zorita) NPP is located in the Guadalajara province of Spain approximately 66 km northeast of Madrid. It is a single loop Westinghouse Pressurized Water Reactor (PWR) design cooled by the waters of the River Tajo. The plant was synchronized to the grid in 1968 and was permanently shutdown on April 30, 2006. UNION FENOSA Generacion has been the owner and operator of the plant and will hand over decommissioning activities to Empresa Nacional de Residuous Radiactivos, S.A. (ENRESA) in approximately two years. During the fall and winter of 2006, Westinghouse Electric Company performed a Full System Decontamination (FSD) in preparation for decommissioning activities. The FSD was performed on the Reactor Coolant System (RCS) including the Residual Heat Removal System (RHRS) and the Chemical Volume and Control System (CVCS). The FSD was performed to facilitate decommissioning activities by reducing general area dose rates and lowering contamination levels to reduce disposal costs. (authors)

    Arenal Volcano is a small stratovolcano located 90 km NW of San Jose, Costa Rica. In 1968 current activity began with a Plinian phase, and has continued to erupt lava flows and pyroclastic flows intermittently since. Samples from the Plinian, pyroclastic flow, strombolian, and effusive phases have been studied texturally. Little variation in crystallinity occurs amongst the different phases. Number density of crystals, both 2D and 3D are 50-70 mm-2 and 30,000-50,000 mm-3 in the Plinian sample, compared to the lesser values in other eruptive types. Characteristic crystal size also increases as explosivity decreases. Two samples, both lava flows collected while warm, overlap with the Plinian sample. This suggests that the variations seen may be a result of cooling history. Plagioclase differs between the Plinian sample, in which they are only tabular in shape, and the other eruptive types, which contain both tabular and equant crystals. To link decompression paths of the Arenal magma to possible pre-eruptive conditions, we have carried out hydrothermal experiments. The experiments were preformed in TZM pressure vessels buffered at a fugacity of Ni-NiO and water saturation. Phase equilibria results in conjunction with mineral compositions and temperature estimates by previous workers from active lava flows and two-pyroxene geothermometry, constrain the likely pre-eruptive conditions for the Arenal magma to 950-1040° C with a water pressure of 50-80 MPa. Samples that started from conditions that bracket our estimated pre-eruptive conditions were decompressed in steps of 5-30 MPa and held for various times at each step until 20 MPa was reached, approximating average decompression rates of 0.25, 0.025, 0.0013 MPa/s. Comparison of textures found in the natural samples to the experimentally produced textures suggest that the Plinian eruption likely was fed by magma ascending at 0.05-1 m/s, whereas the less explosive phases were fed by magma ascending at 0.05 m/s or less.

    Jose Cabrera Nuclear Power Plant (NPP) is a 14x14 PWR reactor built in 1964 in Spain (160 MWe). The commercial operation started in 1969 and finished in 2006. During year 2009, 377 fuel assemblies from cycles 11 to 29 have been stored in 12 containers HI-STORM 100, and positioned in an Interim Spent Fuel Storage Installation built near the NPP. The spent fuel characterization and classification is a critical and complex activity that could impact all the storage process. As every container has a number of positions for damaged fuel, the loading plans and the quantity of containers depends on the total fuels classified as damaged. The classification of the spent fuel in Jose Cabrera has been performed on the basis of the Interim Staff Guidance ISG-1 from USNRC, 'Damaged Fuel'. As the storage system should assure thermal limitations, criticality control, retrievability, confinement and shielding for radioactive protection, the criteria analyzed for every spent fuel have been the existence/non existence of fuel leaks; damage that could affect the criticality analysis (as missing fuel pins) and any situation that could affect the future retrievability, as defects on the top nozzle. The first classification was performed based upon existing core records. If there were no indication of operating leakers during the concerned cycles and the structural integrity was adequate, the fuel was classified as intact or undamaged. When operating records indicated a fuel leaker, an additional inspection by ultrasonic testing of all the fuel in the concerned cycle was performed to determine the fuel leakers. If the examination results indicated that the fuel has cladding cracks, it was classified as damaged fuel without considering if it was a gross breach or a hairline crack. Additionally, it was confirmed that the water chemistry specifications for spent fuel pool has been fulfilled.

  12. El Filibusterismo and Jose Rizal as “Science Fictionist”

    Directory of Open Access Journals (Sweden)

    Miguel Paolo P. Reyes

    2013-12-01

    Full Text Available Jose Rizal’s El Filibusterismo famously depicts the diff iculties faced by adherents of scientif ic thought in the Philippines during the late nineteenth century. It also contains descriptions of various implements that were uncommon for the time, from a “time bomb” within a lamp to a “specter summoner” that apparently projects hologram-like images—the products of reasonable extrapolations from the known science of the age. These features are common among the forerunners of the modern Anglo-American genre of science fiction, from Mary Shelley’s Frankenstein to a number of works by Edgar Allan Poe. It is far from the objective of this paper to push for Rizal’s canonization as the Father of Filipino Science Fiction, however. Instead, this paper seeks to surface the particular ways Rizal chose to depict the conflicts between knowledge borne of materialist investigation and knowledge from the earthly emissaries of the divine. It argues that in El Filibusterismo, these conflicts are somewhat helpful but at the same time dismissible as irrelevant in the context of a campaign against injustice—helpful in intimidating enemy oppressors, irrelevant among advocates of the downtrodden. In this way, Rizal’s novel implicitly contemplates a way to craft “science fiction” that strays from the imperialistic “science conquers” formula predominant in the West.

    Recent earthquakes and a new way of looking at faults suggest that damaging earthquakes are closing in on the San Francisco area. Earthquakes Awareness Week 1989 in northern California started off with a bang on Monday, 3 April, when a magnitude 4.8 earthquake struck 15 kilometers northeast of San Jose. The relatively small shock-its primary damage was the shattering of an air-control tower window-got the immediate attention of three U.S Geological Survey seismologists in Menlo Park near San Francisco. David Oppenheimer, William Bakun, and Allan Lindh had forecast a nearby earthquake in a just completed report, and this, they thought, might be it. 

  1. Preliminary study of the uranium potential of Tertiary rocks in the central San Juan Basin, New Mexico

    Vizcaino, H.P.; O'Neill, A.J.

    1977-12-01

    Three formations in the Tertiary of the San Juan Basin were investigated for their uranium favorability. They are the Ojo Alamo Sandstone, the Nacimiento Formation, and the San Jose Formation. The study comprised a literature survey and a basin analysis, which consisted of subsurface lithofacies, stratigraphic, and radiometric mapping. Field work in preparation for the subsurface analysis consisted of examination of outcrop and measured sections, surface radiometric traverses, and checking of reported surface radioactive anomalies. Interpretation of subsurface mapping provided the primary basis for favorability assessment. The sandstone trends depicted in lithofacies maps, and stratigraphic cross sections reflect large channel complexes and major fluvial systems originating in favorable source areas. Although surface radioactivity anomalies were found to be few, weak, and widespread, the San Juan Basin has abundant favorable host rocks. The subsurface anomalies, although weak, are widespread and sometimes persist throughout thickness intervals greater than 50 ft. Subsurface anomalies were mapped on a wide-spaced grid and are generalized. On the basis of apparent source, lithology, differential permeability, contents of carbonaceous detritus, and geometry, the Nacimiento Formation and the basal facies of the San Jose Formation in the north-central basin have the greatest potential. The Ojo Alamo Sandstone is less favorable, and the Nacimiento Formation in the southern part of the basin and the upper San Jose Formation are the least favorable of the units studied

  2. Dismantling and decommissioning of Jose Cabrera nuclear power plant

    Rodriguez, A.

    2009-01-01

    With the start of the dismantling works at the Jose Cabrera nuclear power plant now in sight, this is an appropriate moment to look back and consider recent history. The first time that the issue of nuclear power plant dismantling was dealt with was in 1975, at a conference in Paris entitled Nuclear Energy Maturity. Up until then the entire question had been one of design, construction and operation, but since that moment and it has been quite a while since that conference dismantling has begun to be seen as just another activity in the nuclear cycle, a final activity that will sooner or later affect all the facilities, an activity different from its predecessors and with the ultimate objective of restoring the sites for whatever use might be determined. During the 1960s and 1970s, the construction of nuclear power plants was widespread across the entire world. It was the baby boom of nuclear energy and now, forty or fifty years later, we are seeing the arrival of the end of the service lifetime of these plants and are faced with the corresponding general process of dismantling these installations. The dismantling of nuclear power plants has ceased to be an emerging issue and is now consolidated as a regular activity in the nuclear industry, albeit an activity that lacks adequate financing or specific regulation in certain countries. Fortunately this is not the case in Spain, since economic provisions have been planned and the regulatory framework developed. In view of the above, the dismantling of the nuclear power plants is an industrial activity involving specific technologies that implies new professional and business opportunities that should be absorbed and seized by society. In Spain the path followed in this direction has been a long one, as is underlined by the experiences of dismantling the Argos (Barcelona, 1998- 2004) and Arbi (Bilbao, 2002-2005) research reactors, the Andujar Uranium Mill (Jaen, 1991-1995), the Vandellos I nuclear power plant

    San Marino, an independent republic located in north central Italy, in 1983 had a population of 22,206 growing at an annual rate of .9%. The literacy rate is 97% and the infant mortality rate is 9.6/1000. The terrain is mountainous and the climate is moderate. According to local tradition, San Marino was founded by a Christian stonecutter in the 4th century A.D. as a refuge against religious persecution. Its recorded history began in the 9th century, and it has survived assaults on its independence by the papacy, the Malatesta lords of Rimini, Cesare Borgia, Napoleon, and Mussolini. An 1862 treaty with the newly formed Kingdom of Italy has been periodically renewed and amended. The present government is an alliance between the socialists and communists. San Marino has had its own statutes and governmental institutions since the 11th century. Legislative authority at present is vested in a 60-member unicameral parliament. Executive authority is exercised by the 11-member Congress of State, the members of which head the various administrative departments of the goverment. The posts are divided among the parties which form the coalition government. Judicial authority is partly exercised by Italian magistrates in civil and criminal cases. San Marino's policies are tied to Italy's and political organizations and labor unions active in Italy are also active in San Marino. Since World War II, there has been intense rivalry between 2 political coalitions, the Popular Alliance composed of the Christian Democratic Party and the Independent Social Democratic Party, and the Liberty Committee, coalition of the Communist Party and the Socialist Party. San Marino's gross domestic product was $137 million and its per capita income was $6290 in 1980. The principal economic activities are farming and livestock raising, along with some light manufacturing. Foreign transactions are dominated by tourism. The government derives most of its revenue from the sale of postage stamps to

    In Mexico, discharge of waste water not treated is a common problem; this is the case of the Lerma river, where the original clean water contribution of the Almoloya-Lerma-San Bartolo timber-roof system, located in the valley of Toluca, State of Mexico, was replaced by the wastewater of the valley. The attempts to clean the water before their spill have been unfruitful and this has caused the present anaerobic conditions of the river in its entire route including the first receiving stage that is the Jose Antonio Alzate Dam (PJAA), becoming a potential source of diseases and a useless water body. In this work we evaluate the treatment efficiency of experimental waste water pond system. The treatment system was constructed with 5 screens which formed 6 internal channels and it had an operation in continuous form by 26 weeks, providing it with continuously polluted water of the Lerma river. We found that the efficiency of reduction of the organic matter reported as BOD, was 83% and it is carried out in the first channel after 7 days of hydraulic retention verifying that the channels do not work like lagoons in series. With the collected data we calculated, through the application of design equations, the factor of decay of organic matter k and the number of dispersion d, specific for the type of treatment and environmental conditions of the site. The required surface of treatment calculated to reach the efficiency of reduction of the DOD5 obtained experimentally. Thus, a surface of: 1 281.6 hectares distributed in 13 lagoons that can deal with a volume 8646.70 m{sup 3}/h was determined. Since this was a bigger surface than that of the dam, the available area was evaluated to make a proposal closer to reallity.

  2. Satellite and ground-based analysis of the effects on vegetation of continuous SO2 degassing at Turrialba volcano (Costa Rica) and its application to hazard management

    Turrialba is an active stratovolcano located 35 km northeast of San Jose, Costa Rica's capital city and socioeconomic hub. After over 100 years of quiescence Turrialba resumed activity in 1996 progressively increasing its degassing and seismic activity, showing continuous gas emissions since 2007. Intermittent phreatic explosions with ash emissions that have reached the capital have occurred since 2010. This activity has resulted in the temporary evacuation of two villages, closure of the National Park that comprises the summit region of the volcano and devastation of the local ecosystem. We combined a variety of satellite-based time series with ground-based measurements of ambient gas concentrations, element deposition and surveys of species richness to enable a comprehensive assessment of SO2 emissions and changes in vegetation. Satellite-based time-series were obtained from Landsat ETM+, Terra ASTER, Terra/Aqua MODIS and Aura OMI, with some of the data dating back to 2000. From 2007-2010 we observed emissions of SO2 and loss of vegetation healthiness (i.e. decrease of EVI2) downwind of the vents. From 2010 onwards these stabilized, but we observe an apparent decrease in agriculture. Other multi-temporal products, such as the ALOS PALSAR FNF data, confirm our observations. The exposure to the volcanic plume resulted in high soil acidity and significant uptake of certain heavy metals by vegetation; in contrast other elements are leached from the soil as a result of the acid deposition. These factors are likely to be responsible for decreased species richness and physiological damage observed at Turrialba. Our study shows ecological impacts, in terms of soil characteristics, vegetation composition and diversity and physiological damage of vegetation, which all correlate to fumigation by Turrialba's plume. Analyzing and relating the remote observations to conditions and impacts on the ground provides a better understanding of volcanic degassing, its impacts on

Topics addressed include the temperature and modulation dependence of spectral linewidth in distributed Bragg reflector laser diodes, length-minimization design considerations in photonic integrated circuits incorporating directional couplers, and the photochemical formation of polymeric optical waveguides and devices for optical interconnection applications

  8. Homogeneous development and segregation - Power dynamics in the urban context: San Jose project case of Manizales city

    International Nuclear Information System (INIS)

    Noguera de Echeverri, Ana Patricia; Gomez Sanchez, Diana Marcela

    2013-01-01

    This article seeks to show specific situations in which power is mobilized by urban dynamics in the context of development as discourse generator homogeneous models of the city. These models are imposed on local contexts to generate economic progress, but their implementation is linked to urban conflicts related with segregation and social exclusion. This aspect points out the inconsistency between the global discourses of development, with local conditions of communities facing directly the results of their application. The arguments presented below are the result of various investigations carried out in the research group Environmental Thought at the National University of Colombia, Manizales headquarters in the context of the environmental crisis, development and the urban environment. In the period 2011-2012, we addressed the topic of the environmental and aesthetic configurations of the city of Manizales, in terms of spatial planning and urban living. This research is the most concrete support of the contextual references expressed in this article, which are based on a strong fieldwork addressed since different social sectors of the city.

  14. Perspective View with Landsat Overlay, Costa Rica

    Science.gov (United States)

    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

    Full Text Available Utilizando datos del Registro Nacional de defunciones de los años 1996-2005 se calcularon las tasas de mortalidad estandarizadas por edad para personas nacidas en Nicaragua versus personas nacidas en Costa Rica. Así mismo, utilizando modelos de regresión binomial se determinaron los riesgos relativos de mortalidad de los inmigrantes nicaragüenses versus personas nativas de Costa Rica con ajustes por edad, urbanización, desempleo, pobreza, educación y segregación residencial. Los hombres y mujeres nacidos en Nicaragua tuvieron un riesgo reducido de mortalidad de 32% y 34% respectivamente con relación a sus contrapartes nacidas en Costa Rica. Se notó que los riesgos de mortalidad por enfermedades infecciosas, cáncer, enfermedades crónicas pulmonares, enfermedades cardiovasculares, y enfermedades crónicas del hígado eran significativamente reducidos entre los inmigrantes nacidos en Nicaragua. El exceso significativo de mortalidad por homicidios se encontró entre los hombres nacidos en Nicaragua (RT = 1,35, 95% IC: 1,19; 1,53 y en mujeres (RT = 1,41, 95% IC: 1,02; 1,95. El riesgo relativo de causas de mortalidad de origen de tipo exógeno entre los inmigrantes nicaragüenses fue más grande entre los grupos de edad joven en áreas de baja densidad de inmigrantes nicaragüenses. La población nacida en Nicaragua residiendo en Costa Rica tiene un riesgo reducido de mortalidad por causas generales versus las personas nacidas en Costa Rica en los años entre 1996-2005. Esto se debe a una mortalidad por enfermedad reducida, la cual es bastante marcada. El homicidio es un una razón de mayor mortalidad entre los inmigrantes nacidos en Nicaragua versus los nativos costarricenses. Hay una gran necesidad de llevar acabo investigaciones adicionales sobre el rol de la migración, estatus socioeconómico y comportamientos entorno a la salud para poder explicar más a fondo los patrones de mortalidad diferenciales entre los inmigrantes nicarag

    1996-01-01

    The rapid population growth in Central America has created pressure on the largest tract of cloud forest spanning the Talamanca Mountains in Costa Rica and Panama. Of immediate concern is restoring hope in the forest and improving the standard of living among local people. Such is the goal of the Amistad Conservation and Development (AMISCONDE) project in the communities of Cerro Punta, Panama, and San Rafael in Costa Rica. Through agriculture, forestry, animal husbandry, environmental education, and community development, AMISCONDE aims to restore the degraded lands in the reserve's buffer zone and improve the income of the people. All the local people, the farmers, women and children have benefited from the project. Some of the activities carried out to meet its objectives include helping the farmers improve the productivity and marketability of their products by teaching them new technologies and giving agricultural credits to farmers, women, and youth groups. In addition, AMISCONDE conducts training courses to address the economic, social and educational needs of women and communities. It is assured that the community and the group will be prepared to continue on their own after the official AMISCONDE office is gone.

  19. Metallothionein and heavy metals in daphnia pulex from Jose Antonio Alzate reservoir

    2001-01-01

    Water and specimens of the freshwater cladoceran Dhapnia pulex were collected at 4 different sites located in an area influenced by industrial, agricultural and urban activities in the Jose Antonio Alzate Reservoir in two different seasons. The Jose Antonio Alzate Reservoir fed by the Lerma river is the first significant water reservoir downstream of the main industrial areas in the State of Mexico. There are about 2,500 industrial discharges between the river source and the Alzate Reservoir which makes the Lerma river and the Jose Antonio Alzate Reservoir the most contaminated water bodies in the State of Mexico. The Monitoring National Network recognises these waters as highly contaminated, especially in the zone located between the Mexico-Toluca highway and the Alzate Reservoir. Water samples and freshwater cladoceran were analysed for Cu and Zn by Energy Dispersive X-Ray Fluorescence (EDXRF) and for Hg and Cd by Neutron Activation Analysis (NAA). As a general feature, the heavy metal concentrations of the water were found to decrease in the sequence: Cu > Zn > Hg > Cd. Metallothioneins (MT) were determined by silver saturation method. Tissue concentrations of MT in Dhapnia pulex varied between 5.69 and 8.96 (mg MT/ g wet wt) in rain season and between 48.87 and 74.00 (mg MT/ g wet wt) in dry season. Metallothioneins levels in Dhapnia pulex were significantly correlated (P < 0.01) with tissue Hg concentrations. In contrast, correlations between MT and tissue levels of Cu and Zn were weak. These observations suggest that Hg2+ activity is the key environmental factor to which metallothionein levels in Daphnia pulex are responding in the studied reservoir

    Radiation controls the temporary storage of waste must ensure that the exterior of the same area is classified as open access. Gamma radiation monitors commonly used ensure that this is the case for this type of radiation. The presence of the neutron field associated with the fission of the fuel and the inherent complexity of the neutron dosimetry, in which information is required to assess spectrometric corresponding dosimetric quantities, has led to this season, first in Spain, measures in containers of waste and spent nuclear fuel in the ATT of the Jose Cabrera.

    Jose de la Vega Elorduy was a doctor in the Spanish Naval Medical Corps who wrote the book entitled Los Rayos X. Memoria sobre Radioscopia y Radiografia in 1899. We have learned that this book, published in Cartagena in 1900, was the first text about Radiology to be published in Spain, rather than that written by Major J. Mitjavila of the Army Medical Corps, as was previously thought. We review the book, stressing its pioneering outlook which provides brief view of the advent of Radiology in the Spanish Navy.

    Central Nuclear Jose Cabrera, also known as Zorita, is a 160 MWe nuclear power plant owned and operated by UNION ELECTRICA-FENOSA, S.A. The plant was supplied by Westinghouse Electric Corporation and commissioned in 1968. It features a unique one loop Pressurized Water Reactor design. The Spanish Licensing Authorities requested C.N. Jose Cabrera to carry out a review of their plant. The main objectives were to reassess the safety adequacy of the operating systems, provide a documented comparison of the plant design versus present day criteria and establish a rationale for departures. Another important objective was to provide prompt identification of any significant deficiency. The review known as phase 1 of the C.N. Jose Cabrera Systematic Evaluation Program, was completed and documented by April 1980

    1985-01-01

    PO 214 , a short life daughter product of RN 222 , was measured by alpha-ray spectrometry of a atmospheric particles sampled on Millipore filters (0.8 μm pore) at Sao Jose dos Campos (23 0 12'S, 45 0 51'W) and Cachoeira Paulista (22 0 41'S, 45 0 00'W). The infleunce of rainfall on the atmospheric Po 214 was studied at Sao Jose dos Campos. The mean activity was 98 pCi/m 3 for dry days (without rain during the preceding two days). On the contrary a low mean activity of 35 pCi/m 3 was observed for high pluviometry days from 08/30 to 10/26 for which total rainfall was 365.5 mm. At Cachoeria Paulista the Po 214 activity was correlated with the stability of the air (measured by the Richardson number), showing an accumaltion of natural radioactive aerosols during periods of higher stability of the lower atmosphere.

    McDougall, Kristin; Block, Debra L.

    2014-01-01

    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.

    Full Text Available El presente artículo forma parte de una serie de investigaciones que se han realizado en el Programa de Investigación en Fundamentos de la Educación a Distancia de la Universidad Estatal a Distancia de Costa Rica en torno al tema del lenguaje y la lectoescritura. Específicamente, este estudio pretendió conocer sobre las concepciones del lenguaje que poseen docentes de I y II Ciclo de Educación General Básica que laboran en la educación pública en escuelas de Costa Rica. Conocer sobre lo que piensa el profesorado sobre el lenguaje es fundamental, porque estos supuestos nos dan una idea de cuáles premisas, teorías y fundamentos parten en su práctica diaria educativa, cómo incide esto en la enseñanza de la lectoescritura y en los procesos mismos de enseñanza-aprendizaje, de tal forma que se reflexione sobre su propia práctica y posiblemente contribuya con el mejoramiento de los procesos formativos. Este fue un estudio exploratorio, se trabajó desde un método mixto y desde las ciencias cognoscitivas y propuestas constructivistas del lenguaje y la lectoescritura. Entre los resultados destaca una práctica intuitiva de parte del personal docente para abordar el tema del lenguaje y la necesidad de contar con una propuesta del lenguaje más robusta que le permita al profesorado potenciar las habilidades lingüísticas más allá de la comunicación.

    Full Text Available Este trabajo analiza las nociones de sociedad, paz y guerra, en La ciudad de Dios, de San Agustín, a la que nos referimos principalmente según la edición bilingüe preparada por José Morán (1965. En una primera parte, a modo de introducción, se expone el argumento general del libro y se explica la teoría de las dos ciudades, la terrena y la de Dios. Enseguida se analiza la noción de sociedad, que se fundamenta en la justicia y en el interés común como camino para alcanzar la paz. Esto nos lleva a examinar la justicia, que para San Agustín es un concepto fundamental tanto en la ciudad terrena como en la ciudad de Dios. Teniendo este marco conceptual en cuanto la sociedad y la autoridad, se entra a discutir la paz, que representa uno de los aspectos centrales de la obra que comentamos. En contraste y como oposición a la paz se analiza la guerra; para nalizar con un tema cuyo origen clásicamente se atribuye a San Agustín, cual es la guerra justa.

Methods: Levels of 25-hydroxyvitamin D, calcium, phosphorus, intact parathyroid hormone (iPTH, and creatinine were measured in 80 people. Solar ultraviolet radiation exposure and 25-hydroxyvitamin D intake were estimated using a previously designed questionnaire. Participants were 52 women aged (mean ± standard deviation 35.8±10.0 years old, body mass index of 27.1±5.9 kg/m2, and 26 men aged 36.4±10.8 years old, body mass index of 27.5±5.0 kg/m2. Results: All participants were normocalcemic, eight females were postmenopausal, three were hypertensive; none had renal, gastrointestinal, or thyroid disease. The level of 25-hydroxyvitamin D was 23.9±7.0 ng/dL and iPTH 40.1±17.5 pg/dL. A level of 25-hydroxyvitamin D $30 ng/dL was seen in 17% of the population. The eight participants with iPTH higher than 67 ng/dL, had 25-hydroxyvitamin D of 18.9±4.8 ng/dL. Two participants who received 25-hydroxyvitamin D and calcium supplements were excluded. Conclusion: The 25-hydroxyvitamin D insufficiency and deficiency found in healthy employees from an academic center in Costa Rica may be due to working long hours in-doors and solar ultraviolet radiation exposure. It is unknown whether secondary hyperparathyroidism seen in nearly 10% of this population, may have long-term effects on bone health. Keywords: vitamin D deficiency, osteoporosis, secondary hyperparathyroidism

    Benavides, E.

    1997-01-01

    The Spent Resin Tank (WD-22) is located in the Auxiliary Building of Jose Cabrera Nuclear Plant (PWR 150 Mwe). This tank has a nominal capacity of 4 m 3 and is almost full of spent resins that has been stored from the late sixties to early eighties. As the lines are completely plugged with resins and due to the difficulties in the pipe lay-out, it has not been possible to transfer the resins to the cementation plant since that date. The plant decided, by an open bid quotation, to select the most suitable process to transfer the resins to the cementation plant avoiding the high doses existing in the tank cubicle and in a reasonable time schedule. The solution given in this paper contemplates that sometimes there is an imaginative answer to a problem that seems to be difficult to solve. (authors)

    2006-01-01

    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

    To identify the influence of gender stereotypes on eating habits among Costa Rican adolescents. Qualitative, descriptive research was used in this study. Adolescents and parents were recruited from socioeconomically diverse populations in rural and urban areas of San José, Costa Rica. Subjects were 92 adolescents (14 to 17 years old) and 48 parents. Focus group data were transcribed and entered into the qualitative data analysis software Atlas.ti version 5.0. Analyses were grounded on the social cognitive theory. Five themes emerged from the focus group discussions: (1) Costa Rican adolescents associate the consumption of moderate quantities of healthy foods with femininity and male homosexuality. (2) The consumption of hearty portions of nonhealthy foods was associated with masculinity and male heterosexuality. (3) There is an emerging view that it is acceptable for heterosexual male adolescents to take care of their bodies through healthy eating. (4) Body care among female adolescents is an element of femininity and body image. (5) Parents reinforce their daughters' persistent concern with weight control because they perceive it as feminine behavior. Health promoters should be aware of the existing and changing food stereotypes around gender as an avenue for the promotion of healthy eating.

    Flow and water-quality changes were studied during a period of intense rainfall in the San Juan Lagoon system. The study covered a 25-hour period beginning 0900 hours 22 October, 1974. Precipitation during the study period averaged 70 millimeters. Sampling stations were located at Boca de Cangrejos, the main ocean outlet; Canal Pinones between Laguna de Pinones and Laguna La Torrecilla; Canal Suarez between Laguna San Jose, connects to Laguna La Torrecilla; and Cano de Martin Pena between Laguna San Jose and Bahia de San Juan. In addition water-elevation recording gages were installed at each lagoon. Water samples from the canal stations were analyzed for organic carbon, nitrogen and phosphorus species, and suspended sediment. Specific-conductance measurements were used with the chemical data to estimate the runoff contributions of nutrients. Runoff into the lagoon, system during the study period was about 2.8 million cubic meters, or about 70 percent of the average precipitation. The runoff contributed chemical loadings to the lagoons of 95,000 kilograms total-organic carbon; 2,700 kilograms of total phosphorus; and 10,000 kilograms of total Khjeldhal nitrogen. A comparison with a prior study during which there was no significant rain, show that dry-period loadings are less than 10 percent of the wet-period loadings. At the end of the study period the system had not reached equilibrium, and the lagoons retained 80 percent of the water inflows from 50 to 90 percent of the chemical loads. Nearly 95 percent of the water outflows occurred at the Boca de Cangrejos sea outlet. The three lagoons and interconnecting canals form a very complex hydraulic system that is difficult to study using traditional techniques. A model of the system will facilitate management to improve the quality of water in the lagoons.

    To estimate the prevalence of enteric parasites and selected vector-borne agents of dogs and cats in San Isidro de El General, Costa Rica, fecal and serum samples were collected from animals voluntarily undergoing sterilization. Each fecal sample was examined for parasites by microscopic examination after fecal flotation and for Giardia and Cryptosporidium using an immunofluorescence assay (IFA). Giardia and Cryptosporidium IFA positive samples were genotyped after PCR amplification of specific DNA if possible. The seroprevalence rates for the vector-borne agents (Dirofilaria immitis, Borrelia burgdorferi, Ehrlichia canis, and Anaplasma phagocytophilum) were estimated based on results from a commercially available ELISA. Enteric parasites were detected in samples from 75% of the dogs; Ancylostoma caninum, Trichuris vulpis, Giardia, and Toxocara canis were detected. Of the cats, 67.5% harbored Giardia spp., Cryptosporidium spp., Ancylostoma tubaeforme, or Toxocara cati. Both Cryptosporidium spp. isolates that could be sequenced were Cryptosporidium parvum (one dog isolate and one cat isolate). Of the Giardia spp. isolates that were successfully sequenced, the 2 cat isolates were assemblage A and the 2 dog isolates were assemblage D. D. immitis antigen and E. canis antibodies were identified in 2.3% and 3.5% of the serum samples, respectively. The prevalence of enteric zoonotic parasites in San Isidro de El General in Costa Rica is high in companion animals and this information should be used to mitigate public health risks.

    Full Text Available From January to July 1995, a market trial was conducted in Costa Rica with the fresh water fish species. Colossoma macropomum, commonly named “tambaqui”. About 1200 fish with an average weight of 800g were obtained from the fish culture station of the Universidad Nacional near La Rita, Guápiles. About 20 fish were delivered each Monday initially to three and later to each of four fishdealers in Limón, Guápiles, San José and Heredia. The shopkeepers purchased the fish at a price of $1.40/kg, covering all production and transport costs, and sold it for $1.97/kg. The motivations of the consumers for purchasing the fish were: curiosity, low price, good taste and recommendations by the shopkeepers. Most of the participants appreciated the taste, meat texture, freshness, colour and appearance very much. Some repondents criticized the amount of intramuscular spines in the fish. Eighty nine percent of the consumers intended to purchase more of the fish and 38% preferred this fish species above all other species. There was no effect (p > 0.05 of gender, householdsize or income level on the responses of the costumers. Chinese costumers were the only group discernible in the survey. Almost all participants thought tambaqui could get a good market position in Costa Rica. This trial shows that the price can be increased a little without losing much customers, but promotion would be necessary to get the product more known among the Costa Rican Population. The production of tambaqui could meet part of the demand for low priced fish in Costa Rica.

    The analytical method validation has been conducted for the simultaneous determination of 15 carbonyl compounds, the main aldehydes and ketones present in ambient air. The compounds have been captured on cartridges packed with silica gel impregnated with 2.4-dinitrophenylhydrazine (DNPH) at a constant flow of about 1 lmin -1 . Carbonyl compounds present have formed the respective products, which are then eluted with acetonitrile (solid phase extraction). The extracts were analyzed by the technique of high resolution liquid chromatography with ultraviolet detector at a wavelength of 360 nm. The following results were obtained during method validation: linearity from 0.03 mgl -1 to 15 mgl -1 , limits of detection and quantification of 0.02 mgl -1 and 0.06 mgl -1 , the accuracy no significant bias at a confidence level of 95%, accuracy for repeatability and producibility of the analytical method are around 1%. Two sampling campaigns were made in dry and rainy seasons of 2009 for areas of San Jose, Heredia and Belen. The predominant compounds were found to be acetone, acetaldehyde and the formaldehyde was the most abundant in the city of San Jose, others do not have significant amounts, so there is strong correlation between formaldehyde and acetaldehyde suggesting that stem from a common source, possibly vehicle emissions.

    Costa Rica takes a power generation system using hydro power generation as the main source, and possesses medium-capacity gas turbines to supplement needs in the dry season and the peak load. However, a problem has come up that, in addition to the cost rise in gas turbine fuel, the power generation efficiency has been aggravating due to aged deterioration of the generators being used. In association therewith, the problem is now a factor to increase CO2 emission, which is a worldwide problem. Keeping in mind to link it to the clean development mechanism (CDM), the present project is, taking up the SAN ANTONIO power plant as the investigation object, intended to perform a comprehensive discussion on the CO2 emission reducing effect, profitability, and proliferation effect, by executing the conceptual plant design. The up-grading plan for thermal power generation systems in Costa Rica consists of replacement of the gas turbines, handling of phase modifiers, and achievement of the combined cycle. The plan agrees with the present feasibility study intended of CO2 emission reduction, consisting of the modification plan of the SAN ANTONIO power plant, that is the plan to replace the over-aged gas turbines at the power plant. Its necessity has been identified. It was disclosed that the project has the effects of reducing CO2 of 82,000 tons annually, and the investment can be recovered in nine years. (NEDO)

    This paper describes the following advances in the methodology for Analysis of External Events in the PSA of the Jose Cabrera NPP: In the Fire Analysis, a version of the COMPBRN3 CODE, modified by Empresarios Agrupados according to the guidelines of Appendix D of the NUREG/CR-5088, has been used. Generic cases were modelled and general conclusions obtained, applicable to fire propagation in closed areas. The damage times obtained were appreciably lower than those obtained with the previous version of the code. The Flood Analysis methodology is based on the construction of event trees to represent flood propagation dependent on the condition of the communication paths between areas, and trees showing propagation stages as a function of affected areas and damaged mitigation equipment. To determine temporary evolution of the flood area level, the CAINZO-EA code has been developed, adapted to specific plant characteristics. In both the Fire and Flood Analyses a quantification methodology has been adopted, which consists of analysing the damages caused at each stage of growth or propagation and identifying, in the Internal Events models, the gates, basic events or headers to which safe failure (probability 1) due to damages is assigned.

    In the Sao Jose do Rio Pardo region, Sao Paulo and Minas Gerais States, occur some intrusive, folded tabular bodies of mangerites associated with hornblende granitoids. The country rocks correspond to a complex association of gneisses and migmatites, locally with granulite facies assemblages. Both the magnerites and hornblende granitoids present a tectonic foliation with mineral flattening and stretching. Petrographically the mangeritic rocks are mainly dark green quartz mangerites with mesoperthite, plagioclase, quartz, hypersthene, clinopyroxene and variable amounts of hornblende, with zircon as conspicuous acessory. The pink hornblende granitoids are mainly granite s.s. exhibiting higher quartz and amphibole contents and lacking pyroxenes. Hololeucocratic alkali feldspar granites are locally associated to the hornblende granites. The textures of the mangerites and granites almost always show an important metamorphic overprinting, with relictic mesoperthite and pyroxene crystal into a granoblastic matrix. The magneritic-granitic suite is characterized by relatively high Fe/(Fe + Mg), K and HFS elements and low Ca contents, being comparable to typical anorogenic magneritic-granitic suites from Svcandinavia and North America. The Rb/Sr data indicate a Late Proterozoic metamorphic isotopic rehomogenization (930 Ma, Ro = 0.706). Geological evidence suggest that the intrusive age could be Middle Proterozoic, wich is reinforced by another Rb-Sr value of about 1300 Ma. (author) [pt

    An area of about 400Km 2 was mapped in the region of Sao Jose dos Quatro Marcos, southwestern State of Mato Grosso, western Brazil. Various granitoid rocks were recognized, intrusive into basement gneisses, and mapped as two distinct units, one of massive late granitoids (mostly 3a and 3b granites) and one of foliated granitoids, with oriented mafic minerals, consisting mainly of tonalites and, to a lesser degree, of granodiorites. The sequence of intrusion is from tonalites to granodiorites to late granites. Magmatic textures are usually preserved in the rocks, with the exception of some clearly recrystallized samples. Field aspects, as well as petrography and mineralogy, suggest a genetic relationship between the various granitoid types, showing overall features commonly cited as typical of 'I' lineages. A Rb/Sr whole-rock isochron obtained from 3b granites (six points) shows an age of 1,472 +- 19 Ma, and Sr 87 86 initial ratio of 0.7037 +- 0.0004; a nine point isochron (adding two tonalites and one granodiorite) yelds similar results (age of 1,505 +- 20 Ma, initial ratio of 0.7029+- 0.0003). The obtained ages confirm the existence of a thermal-magmatic event at about 1,500 Ma at the southern border of the Amazon Craton. (author) [pt

    Full Text Available This article analyses the relationship among entrepreneurship, innovation and growth path regarding the technological cluster in São Jose dos Campos, state of São Paulo. This is an exploratory and descriptive study, supported by documental research and questionnaires applied in a non-probabilistic sample. The results show a relevant social reorganization since CTA/ITA were implemented, in the early Fifties’, which coincides with the arrival of international companies, attracted by the Geographic aspects, high qualified manpower availability and tax benefits. Since then, the municipality has experienced an intense migratory flow of professionals, professors, civil and military students. CTA and ITA generate a considerable level of technological knowledge spillover. Due to it, a number of new companies have started-up operations locally in fields such as Aeronautics, Airspace, Automobile and Petrochemical, which promoted a remarkable social and economic development. Nevertheless, the small and medium technology-based enterprises seem to show high dependence of the core companies in the region that leads to initial stages of internationalization.

    Within the process of renewal of Exploitation Permit of Jose Cabrera Nuclear Power Plant, UNION FENOSA GENERACIO, S. A. (UFG) has carried out an analysis and evaluation project regarding human factors implications of current control room panel arrangement. The project has been developed in two phases. In the first phase, leaded by EPRI and carried out by experts from SAIC, an independent review from a double viewpoint of human reliability and human factors was developed. In the second phase, a multidisciplinary team (composed by human factors, risk analysis, operation, engineering, training and instrumentation and controls experts) has developed a study on human factors implications of current panel arrangement, following the methodology pointed out in NUREG-0711. The project has been developed under the direction of Brookhaven National Laboratory (BNL), organisation that has authored the aforementioned methodology, with the participation of UFG and SOLUZIONA Ingenieria. For the development of the second study the following steps were taken: Firstly, the potential effects of panel arrangement on crew performance were identified its real evidence was analysed and the goals for the improvement of control room operation were established; following NUREG-0711. After this, several design alternatives that addressed these goals were identified and were analysed along three dimensions: human factors, risk analysis and economic costs. Finally the results of these evaluations were combined using a multi-attribute decision method to arrive at a recommended alternative as he best proposal to incorporate human factors criteria and good practices in the design of control room panels.

    Radioecology studies contribute to the monitoring of both anthropic and natural radionuclides, as well as their correlation with the ecosystem and the population. Terrestrial sources, which mainly include the primary radionuclides of the 238 U, 232 Th, and 40 K series, contribute to a higher effective dose received by humanity, with 84% from terrestrial radionuclides and another 16% derived from cosmogenic nuclides. Areas with high levels of natural radiation, above the acceptable limits, are of great relevance for the development of dosimetry studies, whose core aims include the preservation of the environment and the control of the population's exposure to radiation. The town of Sao Jose de Espinharas, Paraiba, Brazil, has a uranium oxide mine with an average grade of 1,200 mg/kg. In the present study, non-destructive, in situ assays were performed along the entire radiometrically anomalous area. The results obtained in terms of effective doses varied from 3.79 to 93.80 mSv.y -1 , with an average of 19.47 mSv.y -1 thus leading to the conclusion that all of the monitored points presented environmental doses of above the reference value of 2.4 mSv.y -1 , suggesting that both qualitative and quantitative analyses concerning the environmental matrixes in question need to be performed.

    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.

    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.

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.

    2007-06-01

    Full Text Available The study focuses on Jose Rizal’s participation in Philippine Theater during the last decades of the nineteenth century. It starts with a careful inventory of attitudes towards existing theater forms and a description of the culture of theater as conceived and imagined in Rizal’s Noli Me Tangere (1887 and El Filibusterismo (1891. In Chapter 20: “The Town Council’s Meeting” in Noli Me Tangere, the study zooms in on the debate on what would be the best and most appropriate theatre piece for the town fiesta. Here, Rizal delineates theater enmeshed in issues of power and Spanish colonialism. He notes as significant the ilustrados’ claim to theatre space and ideology, thereby interrogating Spanish hegemony. The debate becomes the central imagery and situation for Rizal’s analysis and construction of the history of Philippine theater in the novel. Conservative and radical elements duel. The conflict becomes sharper as Rizal continues his critique by putting into his fictional world the very historical actors known at that time; namely, Nemesio Ratia, Jose Carvajal and Praxedes Julia Fernandez (also known as “Yeyeng”. They were part of the comedia troupe hired by the town for the fiesta. In Rizal’s second novel, El Filibusterismo, we encounter the events surrounding the presentation by a French opera troupe in Teatro de Variedades, which Rizal considers as the Manila theater model. The features of this model include a particular ticket system, various kinds of audiences, imported dramatic texts which were largely incomprehensible, actors behaving as actors both on-stage and off-stage, and the Teatro de Variedades space as stage for seizure or possession of power. When the students in the audience stage a walk-out in the theatre of the city and when in provincial San Diego, a stampede cuts short a comedia performance, the interrelationships between society and a discourse of power are revealed.Rizal’s annotations of Philippine

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

    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

    The potential of Euglossini bees, especially Euglossa, as biological indicators of organic vs nonorganic coffee farms was studied in Atenas and San Isidro, Alajuela, Costa Rica using 1.8-cineole as lure. Observations were made for three days at each of four farms and complemented with data from a year of observations. Orchid bees were in greater abundance in the organic farms (t-Student test). However, lower abundances suggest that an organic farm may be negatively affected by the proximity of non-organic farms, depending on its size and distance. Orchid bees may be indicators of organic coffee farms.

    2012-01-01

    Located in central Spain, near Madrid, the Jose-Cabrera NPP (also known as Zorita) is the first PWR to be dismantled in Spain. The unit is a one-loop Westinghouse PWR, with a capacity of 150 MW. The plant was shut down in 1996 and ENRESA (Empresa Nacional de Residuos Radioactivos) has decided its prompt decommissioning, starting in 2010. In preparation for decommissioning, a full system decontamination (FSD) of the whole reactor cooling system (including the reactor vessel in the flow path) was carried out in 2006-7. The large components to be dismantled include: the reactor pressure vessel (RPV) and the internals; the vessel head; the SG; the pressurizer and the surge line; the reactor coolant pump, and the primary loop piping The objective of the project is not only to ensure the safe and efficient dismantling of those large components, but also to gain experience and to learn lessons to be applied during the future decommissioning and dismantling of the remaining six operating PWRs in Spain, whose operational lives are currently planned to end between 2021 and 2028. ENRESA has defined a waste-management policy for decommissioning activities, which includes Waste-management routes and optimisation. A case study describes the results obtained by ENRESA in the specific case of CNJC large components (including the RPV) dismantling project: Removal and conditioning of large components as a single piece is not considered a viable option. Segmentation therefore is required and 2 options have been analysed: large pieces for disposal in a large container and small pieces for disposal in approved concrete packages (CE-2a and the smaller CE-2b). The use of the CE-2b package is a feasible option and is easy to implement as a logical extension from the CE-2a. The use of the CE-2b package results in an important reduction in the total volume of final waste packages and does not require, in itself, any changes in the current waste handling and kinematics.

    Before small-angle neutron scattering (SANS), chain conformation studies were limited to light and small angle x-ray scattering techniques, usually in dilute solution. SANS from blends of normal and labeled molecules could give direct information on chain conformation in bulk polymers. Water-soluble polymers may be examined in H 2 O/D 2 O mixtures using contrast variation methods to provide further information on polymer structure. This paper reviews some of the information provided by this technique using examples of experiments performed at the National Center for Small-Angle Scattering Research (NCSASR)

    The Astronomy Diagnostic Test 2.0 (ADT) was administered to 26 sections of ASTR 101 at MiraCosta College (MCC) from fall 2004 through summer 2007. MiraCosta is a two-year community college located in Oceanside, CA, USA (roughly 40 miles north of San Diego) with an enrollment of approximately 11,000 students. ASTR 101 is MiraCosta's introductory astronomy survey course for non-science majors and has no math prerequisite. Class sizes ranged from 10 to 38 students. Comparison with the ADT National Project results indicates similar pre- and post-course averages: 31.8% (MCC) vs. 32.4% (National) for pre-course tests and 49.3% (MCC) vs. 47.3% (National) for post-course tests. The sample sizes are 709 and 530 students for the pre- and post-tests, respectively. The normalized gain for the entire data set is 0.256 and the effect size (ES) is 1.04, meaning that approximately 85% of the post-test scores are above the average of the pre-test scores. Previous studies have shown the ADT to be a reliable indicator of pre-course misconceptions while post-course scores are useful for comparing modes of instruction and assessing student learning on a limited number of concepts. Additional analyses of the MCC data probe for trends with variables such as gender, class size, and implementation of materials designed for a more "learner-centered” approach (such as Lecture Tutorials, Ranking Tasks, and Think-Pair-Share questions), as well as gains for a particular subset of concepts.

    In this paper a theoretic model is proposed to calculate the gas velocity in the subsoil based on radon concentration variations. The general transport equation for radon in a homogeneous soil with constant porosity is assumed. The diffusion coefficient and the gas velocity being constant. In order to illustrate the model, three geological areas were considered: the Irazu and Arenal volcanoes, situated in the volcanic range in costa Rica, and the Agua Caliente fault located in San Jose, Costa Rica.

    Full Text Available Oropharyngeal and cloacal swabs from 117 captive psittacine birds presented at veterinary clinics (88 and from shelters/rescue centers of wildlife (29 were collected to determine the prevalence of C. psittaci in captive birds in Costa Rica. Samples were collected during 2009 from a total of 19 different species of parrots, with Ara macao (33, Amazona autumnalis (24, Amazona ochrocephala (21, and Ara ararauna (8 being the most representative species sampled. C. psittaci was detected in four (3.4% birds using molecular detection (PCR. The positive samples belonged to birds presented at veterinary clinics; three of them were Ara macao and one Amazona ochrocephala. Three birds were adults; all positive birds showed no symptoms of illness and lived in homes with other birds, two in San José and two in Heredia. Sequencing was used to confirm the PCR positive results, showing that two samples of C. psittaci belonged to genotype A, representing the first report of the presence of this genotype in Costa Rica. The detection of this bacterium in captive psittacine birds shows that there is a potential risk for people living or having contact with them and that there is a possibility of infecting other birds.

    Full Text Available The dependence on fossil fuels urges society to seek for clean energy alternatives, in order to mitigate the effects of climate change. The objective of this study was to determine the potential of solar energy used for water heating and electricity generation. The study was conducted at the dairy of the Technology Institute of Costa Rica, San Carlos Headquarter, from May 15 to April 2016. The data related to the amount of the electricity produced and the temperature reached by water was obtained from the installed photovoltaic and thermal systems, the data was recorded by a computerized register. The obtained information about electricity production allowed researchers to calculate the amount of carbon dioxide equivalent that was not emitted into the atmosphere, and also the acquired economic saving on consumption. The use of these systems allowed the production unit have a self- sufficient source of electrical energy percentage, actually around 30 to 40% of the total electrical consumption. According to the energy production, the solar thermal system was capable to increase water temperature between 20 to 37 °C, temperature that represents more than 70% of the energy needed in order to reach the required water temperature (70 °C for cleaning and sanitizing the milking equipment, and also an economical saving around $90 per month was achieved. The results showed that these systems allow to improve the economical and productive efficiency of agricultural production units in the Northern Huetar Region of Costa Rica.

    The Nuclear Science Facility at SJSU was first opened for classes in 1975. It is designed primarily for undergraduate teaching of nuclear chemistry, radiochemistry, tracer techniques, and radiation safety. Utilizing nearly $1.5 million in counting equipment alone, but excluding a reactor or accelerator, it allows simultaneous use of multiple counting assemblages for up to 20 individual students, even for advanced experiments with Ge/MCA units. Current academic programs include a B.S. Degree in Radiochemistry, an M.S. in Radiological Health Physics, and community outreach to grade schools (nearly 2,000 student-experiments for grades 7-12 were performed in AY88/89). To encourage nuclear chemistry as a potential area of study in graduate school, the US Department of Energy funded a special national Summer School in Nuclear Chemistry. This was first held at SJSU in 1984; summer 1990 will see the seventh such program taught

    We estimate the ground motions produced by the 1906 San Francisco earthquake making use of the recently developed Song et al. (2008) source model that combines the available geodetic and seismic observations and recently constructed 3D geologic and seismic velocity models. Our estimates of the ground motions for the 1906 earthquake are consistent across five ground-motion modeling groups employing different wave propagation codes and simulation domains. The simulations successfully reproduce the main features of the Boatwright and Bundock (2005) ShakeMap, but tend to over predict the intensity of shaking by 0.1-0.5 modified Mercalli intensity (MMI) units. Velocity waveforms at sites throughout the San Francisco Bay Area exhibit characteristics consistent with rupture directivity, local geologic conditions (e.g., sedimentary basins), and the large size of the event (e.g., durations of strong shaking lasting tens of seconds). We also compute ground motions for seven hypothetical scenarios rupturing the same extent of the northern San Andreas fault, considering three additional hypocenters and an additional, random distribution of slip. Rupture directivity exerts the strongest influence on the variations in shaking, although sedimentary basins do consistently contribute to the response in some locations, such as Santa Rosa, Livermore, and San Jose. These scenarios suggest that future large earthquakes on the northern San Andreas fault may subject the current San Francisco Bay urban area to stronger shaking than a repeat of the 1906 earthquake. Ruptures propagating southward towards San Francisco appear to expose more of the urban area to a given intensity level than do ruptures propagating northward.

    2013-09-01

    In Central America, palm swamps are known collectively as yolillales. These wetlands are usually dominated by the raffia palm Raphia taedigera, but also by the royal palm Manicaria saccifera and -in lower extensions- by the American oil palm Elaeis oleifera. The yolillales tend to be poor in woody species and are characteristic of regions with high rainfall and extensive hydroperiods, so they remain flooded most of the year. The dominance of large raffia palm leaves in the canopy, allow these environments to be distinguishable in aerial photographs, which consequently has helped to map them along most of their distribution. However, while maps depicting yolillales are available, the extent of their surface area, perimeter and connectivity remains poorly understood. This is particularly true for yolillales in Costa Rica and Nicaragua, countries that share a good proportion of palm dominated swaps in the Rio San Juan Basin. In addition, it is not known the actual area of these environments that is under any category of protection according to the conservation systems of both countries. As a first step to catalog yolillal wetlands in Costa Rica and Nicaragua, this paper evaluates cartographic maps to delineate yolillales in the region. A subsample of yolillales mapped in this study were visited and we geo-referenced them and evaluate the extent and condition of the swamp. A total of 110 883.2ha are classified as yolillales in Nicaragua, equivalent to 22% of wetland surface area recorded for that country (excluding the Cocibolca and Xolothn Lakes). In Costa Rica, 53 931.3ha are covered by these palm dominated swamps, which represent 16.24% of the total surface area covered by wetlands. About 47% of the area covered by yolillales in Nicaragua is under some category of protection, the largest extensions protected by Cerro Silva, Laguna Tale Sulumas and Indio Maiz Nature Reserves. In Costa Rica, 55.5% of the area covered by yolillal is located within protected areas

    1983-07-01

    Faraday rotation data from 1980, obtained with a polarimeter at Sao Jose dos Campos (23 0 S, 46 0 W), were analyzed during periods occurring magnetic storms. In order to select these periods, the magnetic index Dst was used. It was observed that during magnetic storms preceeded by a few calm days, an increase in the Total Electron Content (TEC) is observed during the storm main phase, relative to the mean of the magnetic calm days (positive phase). Afterwards, during the storms recovery phase, a decrease was registered relative to the average (negative phase). This TEC behaviour, observed at low latitudes storms, is typical of the behaviour over medium latitudes. But, when several storms occur with few intervening days between them, the positive phase seems to prevail. This indicates an inibition of the source of the negative phase. This work discusses the possible origins of the positive and negative phases. (Author) [pt

  2. Lead-lead isotope method. Application to migmatites and associaded rocks of the region of Sao Jose dos Campos, SP

    1988-01-01

    Establishment of chemical and analytical procedures, preparation and purification of reagents and the mounting of a clean laboratory (class 100) for the Pb-Pb isotope dating of whole rock and mineral samples are discussed in this work. Two different methods of dissolution of rock samples and chemical separation of lead using anionic resin were tried in a conventional chemical laboratory using analytical grade reagents. The samples analysed were paleossome and neossome of migmatites from Sao Jose dos Campos, SP, and from the results obtained the analytical method to be employed was chosen. The results obtained by this method agree well with those of the Geochronology Laboratory at Oxford, for the same samples. Applying the established analytical procedure, migmatites and associated gneisses from the region of Sao Jose dos Campos were dated by Pb/Pb method. Some of the samples were also dated by Rb-Sr method. The lead-lead isochron age of 2355 +- 85 M.a. (μ 1 = 8.33) for the paleossome may be interpreted as the age of the metamorphism for these rocks, which were formed probably during the Archean. The age data for the phacoidal gneisses show a similar geological evolution, whereas the 2414 +- 800 M.A. Pb-Pb isochron age for the protomylonitic gneisses indicates a disturbed Pb-Pb isotope system. The neossome samples define a Pb-Pb isochron age of 1388 +- 290 M.A. (μ1 = 8.15), which may be interpreted as the age of migmatization. The calculated Pb-Pb ages for two alkali feldspars from the migmatites are devoid of any geological significance. The age values obtained by the Rb-Sr isotope system for the neossome and paleossome of the migmatites agree with the Pb/Pb data within experimental errors. However, the study shows that results of the Rb-Sr data alone cannot be interpreted unambiguously with out comparison with data from other isotope systems. (author) [pt

    We present a crustal deformation velocity map along the San Andreas Fault System by combining measurements from Sentinel-1 Interferometric Synthetic Aperture Radar (InSAR) and Global Positioning System (GPS) velocity models (CGM V1). We assembled 5 tracks of descending Sentinel-1 InSAR data spanning 2014.11-2017.02, and produced 545 interferograms, each of which covers roughly 250km x 420km area ( 60 bursts). These interferograms are unwrapped using SNAPHU [Chen & Zebker, 2002], with the 2Npi unwrapping ambiguity corrected with a sparse recovery method. We used coherence-based small baseline subset (SBAS) method [Tong & Schmidt, 2016] together with atmospheric correction by common-point stacking [Tymofyeyeva and Fialko, 2015] to construct deformation time series [Xu et. al., 2017]. Then we project the horizontal GPS model and vertical GPS data into satellite line-of-sight directions separately. We first remove the horizontal GPS model from InSAR measurements and perform elevation-dependent atmospheric phase correction. Then we compute the discrepancy between the remaining InSAR measurements and vertical GPS data. We interpolate this discrepancy and remove it from the residual InSAR measurements. Finally, we restore the horizontal GPS model. Preliminary results show that fault creep over the San Jacinto fault, the Elsinore fault, and the San Andreas creeping section is clearly resolved. During the period of drought, the Central Valley of California was subsiding at a high rate (up to 40 cm/yr), while the city of San Jose is uplifting due to recharge, with a quaternary fault acting as a ground water barrier. These findings will be reported during the meeting.

    A comprehensive compilation of 651 (since 1968) radiometric ages determinations (415 {sup 40}Ar/{sup 39}Ar, 211 K/Ar, 5 U/Th, 4 Rb/Sr, 2 U/Pb, and 13 fission track thermochronology ages using zircon) have provided a complete picture of the igneous stratigraphy of Costa Rica, and information about the age of the major metamorphic and metallogenic events in the region. Igneous rocks of Late Jurassic to Middle Eocene age ({approx} 160 to {approx} 41 Ma), mainly accreted ophiolites. The actual subduction zone was established, represented by volcano-sedimentary rocks of basic to felsic composition, at the beginning of Campanian time ({approx} 71 Ma). However, voluminous subalkaline, primary volcanic rocks have appeared only after {approx} 29 Ma. Intrusive to hypabyssal granitic to gabboic plutons, stocks, equivalent dykes and sills, are widely exposed in the Talamanca range ({approx} 12,4 - 7,8 Ma), hills of Escazu ({approx} 6,0 - 5,9 Ma), and Fila Costena ({approx} 18,3 - 16,8 and {approx} 14,8 - 11,1 Ma), Tapanti-Montes del Aguacate-Carpintera ({approx} 4,2 - 2,2 Ma) and Guacimal ({approx} 6,4 - 5,2 Ma). Arc rocks between 29 and 11 Ma (called Photo-Volcanic Front) are known in the San Carlos plains and in southern Costa Rica. The location and age of the igneous rocks have indicated that there was a 20 degrees counterclockwise rotation of the arc (termed as Proto-Volcanic Front) between 15 and 8 Ma, with a pole of rotation that has centered on southern Costa Rica. This rotation is attributed to deformation in the overriding plate (shortening in the south coeval with extension in the NW), accompanied by trench retreat in the south. At {approx} 3,45 Ma, arc-related volcanism has shut off in southern part of the region, but local acid-adakite volcanism has persisted in the Talamanca range (4,2 - 0,95 Ma) due to the subduction of the Cocos Ridge. The Paleo-Volcanic Front is represented by arc-related rocks (8 - 3,5 Ma) along the length of Costa Rica, parallel to but in

    The five sheets of the San Francisco folio the Tamalpais, Ban Francisco, Concord, Ban Mateo, and Haywards sheets map a territory lying between latitude 37° 30' and 38° and longitude 122° and 122° 45'. Large parts of four of these sheets cover the waters of the Bay of San Francisco or of the adjacent Pacific Ocean. (See fig. 1.) Within the area mapped are the cities of San Francisco, Oakland, Berkeley, Alameda, Ban Rafael, and San Mateo, and many smaller towns and villages. These cities, which have a population aggregating about 750,000, together form the largest and most important center of commercial and industrial activity on the west coast of the United States. The natural advantages afforded by a great harbor, where the railways from the east meet the ships from all ports of the world, have determined the site of a flourishing cosmopolitan, commercial city on the shores of San Francisco Bay. The bay is encircled by hilly and mountainous country diversified by fertile valley lands and divides the territory mapped into two rather contrasted parts, the western part being again divided by the Golden Gate. It will therefore be convenient to sketch the geographic features under four headings (1) the area east of San Francisco Bay; (2) the San Francisco Peninsula; (3) the Marin Peninsula; (4) San Francisco Bay.

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

    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].

    The correlations between the activity of the short half-life radon decay products in the low atmosphere and the meterological parameters, measuring the atmospheric polonium 214 are studied. The aerosols were collected on membrane filters and analysed by alpha spectrometry. Measurements have been made in Sao Jose dos Campos and Cachoeira Paulista, in Brazil. At S. Jose dos Campos the influence of the pluviometry on the concentration of atmospheric Po 214 has been analysed, showing that high activity correspond to low pluviometry and inversely, low activities correspond to high pluviometry. At Cachoeira Paulista, the variation in the atmospheric Po 214 activity in corresation with the air stability, measured, showing the accumulation of radioactive aerosols during the greater stability in the the lower atmospheric layers, was studied.

These analyses were developed following parameters defined by the International Association Wood Anatomist Committee (IAWA Committee 1989) and methods established by the Wood Technology Laboratory of Universidad Distrital. Measurements and descriptions were used to prepare identification keys and similarity analysis. The wood of Caesalpiniaceae family illustrated common characteristics in growth rings differentiation, porosity, vessel arrangement, deposits, diameter and length, plates perforation type, alternate and vestured intervessel pits; fibers wall thickness and length; paratracheal axial vasicentric parenchyma, aliform and banded parenchyma and presence of prismatic crystals. Also, variations in anatomical features such us longitudinal channels were found as diagnostic for some genera like Copaifera. The variation and analysis of anatomical characteristics of the xylem tissue allowed to verify some taxonomic relations of the family Caesalpiniaceae, like the observed with the species Mora megistosperma, Mora oleofera, Peltogyne pubescens, Peltogyne paniculata, Sclerolobium odoratissimum and Tachigali polyphylla .

    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.

    We estimate the ground motions produce by the 1906 San Francisco earthquake making use of the recently developed Song et al. (2008) source model that combines the available geodetic and seismic observations and recently constructed 3D geologic and seismic velocity models. Our estimates of the ground motions for the 1906 earthquake are consistent across five ground-motion modeling groups employing different wave propagation codes and simulation domains. The simulations successfully reproduce the main features of the Boatwright and Bundock (2005) ShakeMap, but tend to over predict the intensity of shaking by 0.1-0.5 modified Mercalli intensity (MMI) units. Velocity waveforms at sites throughout the San Francisco Bay Area exhibit characteristics consistent with rupture directivity, local geologic conditions (e.g., sedimentary basins), and the large size of the event (e.g., durations of strong shaking lasting tens of seconds). We also compute ground motions for seven hypothetical scenarios rupturing the same extent of the northern San Andreas fault, considering three additional hypocenters and an additional, random distribution of slip. Rupture directivity exerts the strongest influence on the variations in shaking, although sedimentary basins do consistently contribute to the response in some locations, such as Santa Rosa, Livermore, and San Jose. These scenarios suggest that future large earthquakes on the northern San Andreas fault may subject the current San Francisco Bay urban area to stronger shaking than a repeat of the 1906 earthquake. Ruptures propagating southward towards San Francisco appear to expose more of the urban area to a given intensity level than do ruptures propagating northward.

    Full Text Available At the end of the last decade many Latin American states initiated public security reform. This included police human rights strategies, which aim to improve police officers' compliance with human rights. Particular strategies emphasized the development of police legal expertise. In Costa Rica this was done through professionalizing police legal training and police legal assistance within the preventive police. Yet the implementation of police human rights strategies is influenced by a wider socio-political and institutional context. 'Around here I am the law' reflects the process of transforming non-professionally trained police officers into professionally trained public officials whose core business is the enforcement of the law. On the basis of empirical research conducted in San José, this paper discusses the effect of implementing police human rights strategies that focus on improving police officers' compliance with the rule of law.

    Full Text Available The potential of Euglossini bees, especially Euglossa, as biological indicators of organic vs non-organic coffee farms was studied in Atenas and San Isidro, Alajuela, Costa Rica using 1.8-cineole as lure. Observations were made for three days at each of four farms and complemented with data from a year of observations. Orchid bees were in greater abundance in the organic farms (t-Student test. However, lower abundances suggest that an organic farm may be negatively affected by the proximity of non-organic farms, depending on its size and distance. Orchid bees may be indicators of organic coffee farms. Rev. Biol. Trop. 54 (3: 965-969. Epub 2006 Sept. 29.Por un año estudiamos las abejas de la tribu Euglossini (abejas de las orquídeas, especialmente el género Euglossa en Atenas y San Isidro, Alajuela, Costa Rica, para identificar su potencial como bioindicadoras de fincas orgánicas y fincas "convencionales" de café. Usamos como atrayente aceite de eucalipto (1.8-cineole. Las abejas son más abundantes en las fincas de café orgánico (t-Student. Sin embargo, el relativamente bajo número de abejas en la menor de las dos fincas orgánicas sugiere que el tamaño de una finca orgánica y la proximidad a las fincas convencionales, podrían tener efectos negativos en la orgánica.

    Full Text Available Se trabajó de junio de 1986 a febrero de 1987 en una estación de muestreo en el estero Palo Seco y en dos en el estero Damas (Damas y San Bosco, Pacífico Central, Costa Rica. La temperatura del agua no presentó diferencias significativas entre las estaciones Damas y San Bosco, pero sí entre Damas-Palo Seco y San Bosco-Palo Seco. La salinidad varió significativamente entre las tres estaciones y el pH no mostró diferencias significativas. Se recolectaron representantes de 25 familias, 39 géneros y 54 especies. De las especies, 18 comparten los tres sitios de muestreo, siete se hallaron únicamente en Palo Seco, cinco en Damas y seis en San Bosco. De las especies recolectadas, el 7,41% es compartido entre Palo Seco y Damas; el 3,70% entre Palo Seco y San Bosco y el 22,22% entre Damas y San Bosco. El análisis de similitud determinó que las estaciones Damas y San Bosco comparten un 41,40% de las especies; mientras que Palo Seco solamente presento un 9,9% de especies comunes con el grupo Damas-San Bosco. La mayoría de las especies encontradas fueron de origen marino que utilizan estos dos esteros como área de crianza (42,59% y alimentación (40,74%; mientras que las de agua dulce, estuarinas y visitantes ocasionales están poco representadas. La mayor diversidad se encontró en San Bosco y se detectaron diferencias estadísticamente significativas en los valores de H' entre las estaciones. La mayor similitud de especies se presentó entre las estaciones Damas y San Bosco, lo que sugiere que estas áreas están bajo una mayor influencia de aguas continentales; lo que propicia que los peces estén más ampliamente distribuidos. Se deduce que la ictiofauna de los esteros estudiados es transitoria en los sitios de muestreo y que la misma se distribuye heterogéneamente.

    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

  9. [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.

    Full Text Available The University of the Philippines Herbarium was established in 1908 and originally located in Ermita, Manila. The majority of its pre-war collections were destroyed during World War II, and no formal records of its specimens were preserved. Since then, multiple efforts to restore and improve the Herbarium have been proposed and implemented, most notably its move to the UP Diliman campus. In 1999, the Herbarium was off icially renamed as the Jose Vera Santos Memorial Herbarium after the noted grass expert, who initiated rehabilitation work in the Herbarium after the war. The Herbarium is registered with the international code PUH in the Index Herbariorum, a global directory of public herbaria managed by the New York Botanical Garden. To assess the accessioned (uniquely numbered and recorded collection of the Herbarium, an electronic database of its accessions was created.The Herbarium currently contains 14,648 accessions, 12,681 (86.6% of which were collected in the Philippines. This is comprised of 309 families, 1903 genera, and 4485 distinct species. Thirty-nine type specimens form part of the collection, only one of which is a holotype. On the basis of major plant groups, angiosperms make up 71% of the collection. Unsurprisingly, Family Poaceae has the largest number of specimens at 2,759 accessions. The earliest dated Philippine specimen was collected by E.D. Merrill in 1902, and roughly half of the total accessioned specimens were collected in the 1950s and 1970s. The two most prolif ic collectors were Santos and Leonardo L. Co, with 2,320 and 2,147 specimens, respectively. Luzon is the most well-represented island group with 2,752 specimens collected in Metro Manila alone. At present, PUH Curator James V. LaFrankie is working on the expansion of the collection and upgrading of the herbarium to encourage future educational and research activities.

    The earth's crust has in its composition the Naturally Occurring Radioactive Material (NORM) that may have increased concentration due to activities of exploration and extraction of environmental resources. The civil construction is an economic activity that requires the use of much of the natural resources, such as the raw material of brick works, like clays, mainly used for the production of bricks and tiles. These construction materials may contain high levels of natural radioactive elements, even with concentrations higher than the limits established, given that the levels vary according to the composition of rocks and soil, due to the geological formation and may result in increased exposure of humans to natural radioactive activities. In this context, the radioecological dosimetry is defined in terms of Radium Equivalent activity (Ra eq ), that ensure radiometric conditions for the use of material derived from clays before its final application in housing construction, an initiative that ensures the radioecological safety of population. Thus, this study aimed to establish the calculation of Ra eq in the raw material of brick works located in Sao Jose do Sabugi city, state of Paraiba, in an area adjacent to the uranium deposits of Espinharas, to estimate the risks associated with primordial radionuclides attributed to TENORM activities (Technologically Enhanced Naturally Occurring Radioactive Materials) from the extraction and use of clay as a raw material in the manufacture of bricks and tiles. Analyses were performed by High Resolution Gamma Spectrometry, with HPGe-Be detector, assuming the state of secular radioactive equilibrium. The results ranged from 183.2 to 747.78 Bq/kg, with an average of 494.6 Bq/kg which exceeded the limit of 370 Bq/kg established by UNSCEAR for construction materials. Some samples obtained values exceeded by up the double this limit, suggesting control and radiometric certification for application of this material. (author)

    Full Text Available Existe poca información publicada sobre el efecto de grandes represas hidroeléctricas (>15m alto en ríos tropicales. Investigamos los efectos de estas represas en las comunidades de macroinvertebrados acuáticos en dos ríos de Costa Rica. Medimos características físico-químicas y recolectamos macroinvertebrados a lo largo del año en dos ríos represados, Peñas Blancas y San Lorenzo, así como en el río Chachagua, el cual no era utilizado para la producción hidroeléctrica. Los sitios arriba y debajo de las represas presentaron diferencias físico-químicas, con amplia variación y valores extremos en las variables medidas debajo de la represa en el Río San Lorenzo. Los sitios arriba de las represas estaban dominados por colectores-recolectores-raspadores y nadadores-colgadores, mientras que debajo de las represas hubo una representación más equitativa de grupos funcionales. En contraste, las comunidades fueron semejantes en dos sitios a diferente elevación en el río sin represa. La presencia de afluentes podría haber facilitado la recuperación de macroinvertebrados arriba de la casa de máquinas, pero las comunidades fueron similares bajo la casa y abajo de la represa. Una liberación masiva de sedimentos disminuyó la abundancia y el número de táxones bajo la represa en el Río Peñas Blancas.

    Full Text Available Triatoma dimidiata has been found in several cities and towns of those countries where the insect is a domestic or peridomestic pest. In Central America, urban infestations occur in the capitals of at least five countries. During 2001 and 2002 a survey was carried out in the county of San Rafael, Heredia province, located 15 km northwest of San José, capital of Costa Rica, in order to determine the degree of infestation by T. dimidiata in an entire city block. Six peridomestic colonies of the insect were detected in the backyards of eight households. The ecotopes occupied by the insects consisted of store rooms with old objects, wood piles or firewood, and chicken coops. A total of 1917 insects were found in the six foci, during two sampling periods, and a mean infection rate by Trypanosoma cruzi of 28.4% was found in 1718 insects examined. The largest colony found in one of the households yielded 872 insects that were thriving mainly at the expenses of two dogs. Opossums and adult insects were common visitors of the houses and it became evident that this marsupial is closely related to the peridomestic cycle of the Chagas disease agent. Lack of colonization of the insect inside the human dwellings is explained by the type of construction and good sanitary conditions of the houses, in contrast to the situation in most peridomiciliary areas. Stomach blood samples from the insects showed that the main hosts were, in order of decreasing frequency: rodents, dogs, fowl, humans, opossums, and cats. The fact that no indication of infection with Chagas disease could be detected in the human occupants of the infested houses, vis a vis the high infection rate in dogs, is discussed.

    Despite the fact that little is known about the consequences of hydropower production in tropical areas, many large dams (> 15 m high) are currently under construction or consideration in the tropics. We researched the effects of large hydroelectric dams on aquatic macroinvertebrate assemblages in two Costa Rican rivers. We measured physicochemical characteristics and sampled aquatic macroinvertebrates from March 2003 to March 2004 in two dammed rivers, Peñas Blancas and San Lorenzo, as well as in the undammed Chachagua River. Sites above and below the dam had differences in their physicochemical variables, with wide variation and extreme values in variables measured below the dam in the San Lorenzo River. Sites below the dams had reduced water discharges, velocities, and depths when compared with sites above the dams, as well as higher temperatures and conductivity. Sites above dams were dominated by collector-gatherer-scrapers and habitat groups dominated by swimmer-clingers, while sites below dams had a more even representation of groups. In contrast, a comparison between two sites at different elevation in the undammed river maintained a similar assemblage composition. Tributaries might facilitate macroinvertebrate recovery above the turbine house, but the assemblage below the turbine house resembled the one below the dam. A massive sediment release event from the dam decreased the abundance per sample and macroinvertebrate taxa below the dam in the Peñas Blancas River. Our study illustrates the effects of hydropower production on neotropical rivers, highlighting the importance of using multiple measures of macroinvertebrate assemblage structure for assessing this type of environmental impact.

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.

  1. Gas measurements from the Costa Rica-Nicaragua volcanic segment suggest possible along-arc variations in volcanic gas chemistry

    Obtaining accurate estimates of the CO2 output from arc volcanism requires a precise understanding of the potential along-arc variations in volcanic gas chemistry, and ultimately of the magmatic gas signature of each individual arc segment. In an attempt to more fully constrain the magmatic gas signature of the Central America Volcanic Arc (CAVA), we present here the results of a volcanic gas survey performed during March and April 2013 at five degassing volcanoes within the Costa Rica-Nicaragua volcanic segment (CNVS). Observations of the volcanic gas plume made with a multicomponent gas analyzer system (Multi-GAS) have allowed characterization of the CO2/SO2-ratio signature of the plumes at Poás (0.30±0.06, mean ± SD), Rincón de la Vieja (27.0±15.3), and Turrialba (2.2±0.8) in Costa Rica, and at Telica (3.0±0.9) and San Cristóbal (4.2±1.3) in Nicaragua (all ratios on molar basis). By scaling these plume compositions to simultaneously measured SO2 fluxes, we estimate that the CO2 outputs at CNVS volcanoes range from low (25.5±11.0 tons/day at Poás) to moderate (918 to 1270 tons/day at Turrialba). These results add a new information to the still fragmentary volcanic CO2 output data set, and allow estimating the total CO2 output from the CNVS at 2835±1364 tons/day. Our novel results, with previously available information about gas emissions in Central America, are suggestive of distinct volcanic gas CO2/ST (= SO2 + H2S)-ratio signature for magmatic volatiles in Nicaragua (∼3) relative to Costa Rica (∼0.5-1.0). We also provide additional evidence for the earlier theory relating the CO2-richer signature of Nicaragua volcanism to increased contributions from slab-derived fluids, relative to more-MORB-like volcanism in Costa Rica. The sizeable along-arc variations in magmatic gas chemistry that the present study has suggested indicate that additional gas observations are urgently needed to more-precisely confine the volcanic CO2 from the CAVA, and from

    Full Text Available The objective of this study was to identify nematodes species of the genus Meloidogyne associated with upland ornamental plants. We sampled ten ornamental species in a commercial nursery in San Isidro, Heredia, Costa Rica between 2011-2012. Morphometric measurements of the stylet length, the tail length, and the hyaline region of J2s, as well as perineal patterns of egg-carrying females were used for identification, Genomic DNA was extracted from single J2s and molecular analyses were performed by amplifying the intergenic region between cytochrome oxidase subunit II of the COII and the long subunit of the ARN ribosomal genes by PCR-RFLP. Combining these methods allowed identification of five species of nematodes of the genus Meloidogyne (M. arenaria, M. hapla, M. hispanica, M. incognita and M. javanica, and new restriction enzyme patterns were reported for M. hapla and M. javanica using AluI. Additionally, a preliminary report of M. hispanica was described by sequencing the 28S and 18S regions.

Ten ornamental species in a commercial nursery were sampled in San Isidro, Heredia, Costa Rica between 2011-2012. Morphometric measurements of the stylet length, the trail length, and the hyaline region of J_2s as well as perineal patterns of egg-carrying females were used for identification, Genomic DNA was extracted from single J_2s and molecular analyses were performed by amplifying the intergenic region between cytochrome oxidase subunit II of the COII and the long subunit of the ARN ribosomal genes by PCR-RFLP. Combining these methods allowed identification of five species of nematodes of the genus Meloidogyne (M. arenaria, M. hapla, M. hispanica, M. incognita and M. javanica), and new restriction enzyme patterns were reported for M. hapla and M. javanica using AluI. Additionally a preliminary report of M. hispanica was described by sequencing the 28S and 18S regions. (author) [es

    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

    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

    1988-01-01

    Marketing natural gas produced in the San Juan Basin of New Mexico and Colorado principally involves four gas pipeline companies with significant facilities in the basin. The system capacity, transportation rates, regulatory status, and market access of each of these companies is evaluated. Because of excess gas supplies available to these pipeline companies, producers can expect improved take levels and prices by selling gas directly to end users and utilities as opposed to selling gas to the pipelines for system supply. The complexities of transporting gas today suggest that the services of an independent gas marketing company may be beneficial to smaller producers with gas supplies in the San Juan Basin

    A study was undertaken to determine experimentally the uptake of pollutants into of the different parts of the water hyacinth (Eichhornia crassipes) found in 'Jose Antonio Alzate' dam in the State of Mexico, Mexico. There is evidence for efficient and significant root accumulation of Ti, Mn, Fe, and Ba; but in the upper parts concentrations was consistently determined by the degree of watering. However, a significant input could be derived from a common generic source, such as the atmospheric deposition. The experimental study would, therefore, indicate that water hyacinth species can be highly effective in providing a control and treatment buffer for toxic discharges to the dam. (author)

    Full Text Available A LA COSTA DE LUIS A. MARTINEZ : LA DEFENSE D’UN PROJET LIBERAL POUR L’ÉQUATEUR ? A la Costa est souvent analysé comme une peinture de moeurs, témoignage de la réalité sociale et politique de l´Équateur de la fin du XIX et du début du XX. En effet, ce roman prétend décrire le conflit traditionnel qui oppose socialement, économiquement et politiquement les Andes et la Côte. Mais il se présente aussi et surtout comme la défense d´un projet libéral pour l´Équateur et développe une démonstration idéologique systématique. En outre, il propose une lecture du sens de la vie et une réflexion sur le devenir de l´homme dont la portée dépasse largement l´argumentation idéologique. Ce sont sans aucun doute ces nuances, introduites tout au long de la narration, qui permettent à l´oeuvre d´échapper à son statut exemplaire, simple témoignage d´une époque, pour proposer une vision personnelle et créative. Muchos han visto en A la Costa una novela de tendencia costumbrista, testimonio de la realidad social y política del Ecuador a finales del siglo XIX y comienzos del XX. En efecto, la novela pretende describir el conflicto tradicional social, económico, político entre Sierra y Costa. Pero es también, y ante todo, la defensa de un proyecto liberal para Ecuador, desarrollando una sistemática demostración ideológica. Además, propone una lectura del sentido de la vida y una reflexión sobre el porvenir del hombre cuyo alcance va más allá de la defensa de un proyecto ideológico. Sin duda son estos matices, introducidos a lo largo de la narración, los que permiten que la obra escape del estatuto de novela ejemplar y testimonial para proponer una visión autónoma y creativa.

    Full Text Available OBJECTIVE: Given that excessive body weight during childhood influences the development of several chronic diseases in adulthood, this study was conducted to determine the prevalence of overweight and obesity in urban and rural Costa Rican elementary school children. METHODS: The study was carried out from July 2000 to April 2001. A total of 1718 students ages 7-12 were selected from 34 schools in the capital city of San José and in other nearby urban and rural areas. Both younger children (ones aged 7 through 9 years and older children (ones aged 10 through 12 years with a body mass index (BMI at or above the sex-specific 85th percentile were considered overweight. The younger children were classified as being obese if their triceps skinfold was greater than or equal to the 85th percentile for age and sex using the percentiles by age for children in the United States of America as normative standards. The older children were considered obese if they had a BMI at or above the sex-specific 85th percentile and both the triceps and subscapular skinfold thickness at or above the 90th percentile. RESULTS: The prevalence of overweight was 34.5%. Children aged 7-9, boys, children from urban areas, and children of a higher socioeconomic status had a higher prevalence of overweight. The prevalence of obesity was 26.2%. A higher prevalence of obesity was found among children aged 7-9, boys, children from urban areas, and children of middle socioeconomic status. CONCLUSIONS: Given the high prevalence of obesity that we found in the Costa Rican children, primary and secondary prevention measures are needed in order to reduce the proportion of deaths due to chronic nontransmissible diseases among Costa Rican adults in the coming decades.OBJETIVO: Dado que el peso corporal excesivo durante la niñez influye en el desarrollo de varias enfermedades crónicas en la adultez, se llevó a cabo este estudio en escolares de nivel primario de áreas urbanas y rurales

    Costa Rica takes a power generation system using hydro power generation as the main source, and possesses medium-capacity gas turbines to supplement needs in the dry season and the peak load. However, a problem has come up that, in addition to the cost rise in gas turbine fuel, the power generation efficiency has been aggravating due to aged deterioration of the generators being used. In association therewith, the problem is now a factor to increase CO2 emission, which is a worldwide problem. Keeping in mind to link it to the clean development mechanism (CDM), the present project is, taking up the SAN ANTONIO power plant as the investigation object, intended to perform a comprehensive discussion on the CO2 emission reducing effect, profitability, and proliferation effect, by executing the conceptual plant design. The up-grading plan for thermal power generation systems in Costa Rica consists of replacement of the gas turbines, handling of phase modifiers, and achievement of the combined cycle. The plan agrees with the present feasibility study intended of CO2 emission reduction, consisting of the modification plan of the SAN ANTONIO power plant, that is the plan to replace the over-aged gas turbines at the power plant. Its necessity has been identified. It was disclosed that the project has the effects of reducing CO2 of 82,000 tons annually, and the investment can be recovered in nine years. (NEDO)

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.

    The Advanced Spaceborne Thermal Emission and Reflection radiometer, ASTER, is an international project: the instrument was supplied by Japan's Ministry of International Trade and Industry. A joint US/Japan science team developed algorithms for science data products, and is validating instrument performance. With its 14 spectral bands, extremely high spatial resolution, and 15 meter along-track stereo capability, ASTER is the zoom lens of the Terra satellite. The primary mission goals are to characterize the Earth's surface; and to monitor dynamic events and processes that influence habitability at human scales. ASTER's monitoring and mapping capabilities are illustrated by this series of images of the San Francisco area. The visible and near infrared image reveals suspended sediment in the bays, vegetation health, and details of the urban environment. Flying over San Francisco (3.2MB) (high-res (18.3MB)), we see the downtown, and shadows of the large buildings. Past the Golden Gate Bridge and Alcatraz Island, we cross San Pablo Bay and enter Suisun Bay. Turning south, we fly over the Berkeley and Oakland Hills. Large salt evaporation ponds come into view at the south end of San Francisco Bay. We turn northward, and approach San Francisco Airport. Rather than landing and ending our flight, we see this is as only the beginning of a 6 year mission to better understand the habitability of the world on which we live.

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

  16. Involvement of Union Fenosa skills in the thermohydraulic area of the Jose Cabrera NPP PSA. Applications of the RELAPS5/MOD2 Code

    When performing a level 1 Probabilistic Safety Analysis (PSA) on a standard power plant, in order to model plant response to the potential occurrence of the various initiating events postulated in a PSA, reference documentation applicable to the type of plant in question is frequently consulted. Because of the specific design characteristics of the Jose Cabrera NPP, most of the reference documentation for the W-PWR-type power plants is not applicable to this plant. To fill in these gaps in the documentation and to construct the most realistic model of plant behaviour possible, assistance was sought from Union Fenosa by way of infrastructure, capabilities and thermohydraulic experience of the Nuclear Engineering and Fuel Group, and especially the use of calculations performed with the RELAP5/ MOD2 code. This paper will provide an overview of the general assistance rendered to the PSA by the technical experts in thermohydraulics, the calculations performed with RELAP5/MOD2 and the influence all of this has had on the development, quality and results of the Jose Cabrera NPP level 1 PSA Project.

    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.

    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.

    The Bay Area Air Quality Management District, the San Francisco Bay Area's air quality regulatory agency, has set a goal to reduce the region's greenhouse gas (GHG) emissions to 80% below 1990 levels by 2050, consistent with the State of California's climate goals. Recently, the Air District's governing board adopted a 2017 Clean Air Plan which lays out the agency's vision and includes actions to put the region on a path towards achieving the 2050 goal while also reducing air pollution and related health impacts. The Plan includes GHG rule-making efforts, policy initiatives, local government partnerships, outreach, grants, and incentives, encompassing over 250 specific implementation actions across all economic sectors to effect ambitious emission reductions in the region. To track trends in atmospheric observations of GHGs and associated species and monitor changes in regional emission patterns, the Air District has established a fixed site network (CO2, CH4, CO) of one generally upwind site (Bodega Bay - on the coast north of Marin County) and three receptor sites (Bethel Island - east of the major refineries, in the Sacramento River Delta; Livermore - east of the bulk of the East Bay cities; and San Martin - south of the major city of San Jose). Having collected over a year of data for each of the fixed sites, the Air District is now investigating spatial and temporal variations in GHG emissions. Concentrating on variations in diurnal cycles, we see the commonly observed pattern of seasonal changes in diurnal amplitude at all sites, with larger variations during the winter than the summer, consistent with seasonally varying daily changes in planetary boundary layer heights. Investigations explore the weekday/weekend effect on the diurnal patterns and the effect of seasonal wind direction changes on the intra-annual variations of the local enhancements. The Air District is beginning to investigate the ways in which the fixed site network reflects the dominant

    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.

    Water, sediments and water lily (Eichornia crassipes) from the Jose Antonio Alzate Dam were analyzed in order to determine concentrations of chromium, iron, nickel, copper, zinc, cadmium, lead and mercury. Mercury, lead, chromium and iron were found in concentrations above permissible limits in water, and in high concentrations in sediments. Cadmium, nickel, copper and zinc never were found in concentrations above permissible limits in water. The highest concentrations of heavy metals in water lily were found in the root. Accumulation factors decreased in the following order: Zn> Cr> Fe> Ni> Cu> Pb> Hg and Cd. Statistical differences (α < 0.5) between the collection samples dates was observed. High correlations between metals concentrations in superficial water, sediment and water hyacinth were also observed. These correlations could indicate that the heavy metals studied here, are originated from a natural source such as sediments or from an industrial source. (Author)

    Irazú (3,432 m) is a stratovolcano situated 50 Km east of San José, the capital of Costa Rica. Major geomorphological features at Irazú are five craters (Main Crater, Diego de La Haya, Playa Hermosa, La Laguna and El Piroclástico), and at least 10 satellitic cones which are located on its southern flank. Its eruptive history is known from 1723. Since then, have ocurred at least 23 eruptions. All known Holocene eruptions have been explosive. The focus of eruptions at the summit crater complex has migrated to the west towards the historically active crater from 1963 to 1965. Diffuse degassing studies are becoming an additional geochemical tool for volcanic surveillance. The purpose of this study is to evaluate the spatial distribution of diffuse CO2 emission as well as CO2 efflux from Irazú volcano. A soil CO2 flux survey of 201 sampling sites was carried out at the summit of Irazú volcano in March 2001. Sampling site distribution covered an area of 3.5 Km2. Soil CO2 efflux measurements were performed by means of a portable NDIR sensor LICOR-800. Soil CO2 efflux values ranged from non-detectable values to 316.1 gm-2d-1 Statistical-graphical analysis of the data showed three overlapping geochemical populations. The background mean is 3 gm-2d-1 and represents 91.3 % of the total data. Peak group showed a mean of 18 gm-2d-1 and represented 1.2 % of the data. Anomalous CO2 flux values are mainly detected in the South sector of the main crater, where landslides have previously occurred. Diffuse CO2 degassing rate of the study area yields 44.2 td-1.

    Hurricanes and related storm surges have devastating effects on near-shore infrastructure and above-ground installations. They also heavily impact groundwater resources, with potentially millions of people dependant on these resources as a freshwater source. Destructions of casings and direct incursions of saline and/or polluted waters have been widely observed. It is uncertain how extensive the effects are on underground water systems, especially in limestone karst areas such as Florida and Puerto Rico. Here, we report regional-scale water level changes in groundwater systems of Texas, Florida and Puerto Rico for the 2017 Hurricanes Harvey, Irma, Jose and Maria. We collected regional scale data from the USGS Waterdata portal. Puerto Rico shows the strongest increase in groundwater levels in wells during Hurricane Maria, with less reaction for the preceding storms Irma and Jose. Increases in water levels range from 0.5 to 11m, with maximum storm surges in Puerto Rico around 3m. These wells are located throughout Puerto Rico, on the coast and inland. In Florida, most wells that show a response during Hurricane Irma are located in the Miami region. Wells located on the west coast show smaller responses with the exception of one well located directly on Hurricane Irma's track. These wells show an increase of 0.2 to 1.7m. In Texas, wells located in proximity to Hurricane Harvey's track show an increase in water level. The effect of groundwater level increases is not limited to the Texas coast, but inland as well. An increase between 0.03 and 2.9m is seen. Storm surges for both Florida and Texas have ranged from 1.8-3.7m maximum. We discuss the findings in the context of local and regional geology and hydrogeology (presence of connected aquifer systems, faulting, presence of carbonate/karst systems etc.).

En el año 2006, el organismo encargado de su custodia, el Instituto de Patrimonio Cultural del Ministerio de Cultura, ejecutó tres etapas de exploración arqueológica, que abarcaron las áreas Traspatio, Patio Central y las Naves Este y Oeste de la edificación. Este trabajo reseña el análisis de la documentación arqueológica obtenida en el sitio, a partir de la realización de dicho proyecto, denominado EACUSAC (Estudio Arqueológico del Cuartel San Carlos, que representa además, la tercera campaña realizada en el sitio. La importancia de este yacimiento histórico, radica en su participación en los acontecimientos que propiciaron conflictos de poder durante el surgimiento de la República y en los sucesos políticos del siglo XX. De igual manera, se encontró en el sitio una amplia muestra de materiales arqueológicos que reseñan un estilo de vida cotidiana militar, así como las dinámicas sociales internas ocurridas en el San Carlos, como lugar estratégico para la defensa de los diferentes regímenes que atravesó el país, desde la época del imperialismo español hasta nuestros días.

  10. SANS from interpenetrating polymer networks

    Full text: Interpenetrating polymer networks (IPNs) have been formed by combining two polymeric systems in order to gain enhanced material properties. IPNs are a combination of two or more polymers in network form with one network polymerised and/or crosslinked in the immediate presence of the other(s).1 IPNs allow better blending of two or more crosslinked networks. In this study two sets of IPNs were produced and their microstructure studied using a variety of techniques including small angle neutron scattering (SANS). The first system combined a glassy polymer (polystyrene) with an elastomeric polymer (SBS) with the glassy polymer predominating, to give a high impact plastic. The second set of IPNs contained epichlorohydrin (CO) and nitrile rubber (NBR), and was formed in order to produce novel materials with enhanced chemical and gas barrier properties. In both cases if the phase mixing is optimised the probability of controlled morphologies and synergistic behaviour is increased. The PS/SBS IPNs were prepared using sequential polymerisation. The primary SBS network was thermally crosslinked, then the polystyrene network was polymerised and crosslinked using gamma irradiation to avoid possible thermal degradation of the butadiene segment of the SBS. Tough transparent systems were produced with no apparent thermal degradation of the polybutadiene segments. The epichlorohydrin/nitrile rubber IPNs were formed by simultaneous thermal crosslinking reactions. The epichlorohydrin network was formed using lead based crosslinker, while the nitrile rubber was crosslinked by peroxide methods. The use of two different crosslinking systems was employed in order to achieve independent crosslinking thus resulting in an IPN with minimal grafting between the component networks. SANS, Transmission electron microscopy (TEM), and atomic force microscopy (AFM) were used to examine the size and shape of the phase domains and investigate any variation with crosslinking level and

    When performing a level 1 Probabilistic Safety Analysis (PSA) on a standard power plant, in order to model plant response to the potential occurrence of the various initiating events postulated in a PSA, reference documentation applicable to the type of plant in question is frequently consulted. Because of the specific design characteristics of the Jose Cabrera NPP, most of the reference documentation for the W-PWR-type power plants is not applicable to this plant. To fill in these gaps in the documentation and to construct the most realistic model of plant behaviour possible, assistance was sought from Union Fenosa by way of infrastructure, capabilities and thermohydraulic experience of the Nuclear Engineering and Fuel Group, and especially the use of calculations performed with the RELAP5/ MOD2 code. This paper will provide an overview of the general assistance rendered to the PSA by the technical experts in thermohydraulics, the calculations performed with RELAP5/MOD2 and the influence all of this has had on the development, quality and results of the Jose Cabrera NPP level 1 PSA Project.

    The recent Voyager missions to Jupiter have highlighted the role of sulphur in volcanic processes on io. Although fumarolic sulphur and SO/sub 2/ gas are almost universal in terrestrial active volcanoes, and rare instances of sulphur lava flows have been reported, sulphur in a pyroclastic form has only been described from Poas Volcano, Costa Rica. Here we amplify the original descriptions by Bennett and Raccichini and describe a recent eruption of pyroclastic sulphur scoria and ejected blocks that are characterised by miniature sulphur stalactites and stalagmites.

Seasonal and daily patterns of total gaseous mercury (TGM) were observed at the main sampling location at the Universidad Nacional, Heredia, Costa Rica. The area (lat. 10.000230 long. -84.109499) is located in the Central Valley of Costa Rica and is 27 km SE of the Poas volcano (lat. 10.199486 long. -84.231388). Measurements were made from May 2008 to May 2009 at this location with some additional values obtained at other sites near the Poas volcano including San Luis and Grecia as well as near, Turrialba and Irazu volcanoes. Total gaseous Hg was determined in samples collected at a height of 2 m using the Tekran 2537A (Tekran Inc.) gas-phase Hg vapor analyzer. Meteorological data (temperature, relative humidity, wind speed, wind direction, radiation and precipitation) were obtained from the airport weather station located at Alajuela. Monthly precipitation is typically 85 mm during the dry season (December to April) with winds from the west. The wet season begins in late April and continues to December with monthly rainfall of 328 mm and winds from the NE. The annual mean temperature is 20 deg. C

    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.

    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.

    The San Andreas fault is considered to be the primary plate boundary fault in southern California and the most likely fault to produce a major earthquake. I use dynamic rupture modeling to show that the San Jacinto fault is capable of rupturing along with the San Andreas in a single earthquake, and interpret these results along with existing paleoseismic data and historic damage reports to suggest that this has likely occurred in the historic past. In particular, I find that paleoseismic data...

    The Cambia sub-basin is located in Colombia's western cordillera and has an extension of 89,39 k m2, it is affected by the Rome ral Fault System. The lithology of the area consists of cretaceous rocks of the Diabasic B/R's Formation which is the basement of the area, this unit is overlaid by the tertiary unit of alluvial terraces of the C.c. River and the quaternary units of the: Plan de Aeromonas Mud flow, and the recent alluvial deposits. This thesis aimed to know the geology, geomorphology, mass movements and the susceptibility to river flood susceptibility. The hazard analysis was based on the cartographic updating and analysis of the geology, fluvial geomorphology, the mass movements' characterization, the flow was calculated via the Swat software based on precipitation data and later on the delimitation of the flooded areas was accomplished by using the Heck-Gar's software plus a qualitative analysis of the sub-basin. The main conclusions of this study are: There is flood hazard within this sub-basin, The flooded hazard areas were delimited for the return periods calculated and these areas require an adequate management. This thesis intended to evaluate the susceptibility analysis but the hazard analysis was accomplished. The methodology used is highly recommended for areas, which have the necessary specification to apply it

    2017-12-01

    As we recover from recent large storms, we need information to support increased environmental and socio-economic resilience of the Nation's coasts. Defining baseline conditions, tracking effects of mitigation actions, and measuring the uncertainty of resilience to future disturbance are essential so that the best management practices can be determined. The US Dept. of the Interior invested over $787 million dollars in 2013 to understand and mitigate coastal storm vulnerabilities and enhance resilience of the Northeast coast following Super-Storm Sandy. Several lessons-learned from that investment have direct application to mitigation and restoration needs following Hurricanes Harvey, Irma, Jose and Maria. New models of inundation, overwash, and erosion, developed during the Sandy projects have already been applied to coastlines before and after these recent storms. Results from wetland, beach, back-bay, estuary, and built-environment projects improved models of inundation and erosion from surge and waves. Tests of nature-based infrastructure for mitigating coastal disturbance yielded new concepts for best-practices. Ecological and socio-economic measurements established for detecting disturbance and tracking recovery provide baseline data critical to early detection of vulnerabilities. The Sandy lessons and preliminary applications on the recent storms could help define best-resilience practices before more costly mitigation or restoration efforts are required.

  16. Perspective View, San Andreas Fault

    Science.gov (United States)

    2000-01-01

    The prominent linear feature straight down the center of this perspective view is California's famous San Andreas Fault. The image, created with data from NASA's Shuttle Radar Topography Mission (SRTM), will be used by geologists studying fault dynamics and landforms resulting from active tectonics. This segment of the fault lies west of the city of Palmdale, Calif., about 100 kilometers (about 60 miles) northwest of Los Angeles. The fault is the active tectonic boundary between the North American plate on the right, and the Pacific plate on the left. Relative to each other, the Pacific plate is moving away from the viewer and the North American plate is moving toward the viewer along what geologists call a right lateral strike-slip fault. Two large mountain ranges are visible, the San Gabriel Mountains on the left and the Tehachapi Mountains in the upper right. Another fault, the Garlock Fault lies at the base of the Tehachapis; the San Andreas and the Garlock Faults meet in the center distance near the town of Gorman. In the distance, over the Tehachapi Mountains is California's Central Valley. Along the foothills in the right hand part of the image is the Antelope Valley, including the Antelope Valley California Poppy Reserve. The data used to create this image were acquired by SRTM aboard the Space Shuttle Endeavour, launched on February 11, 2000.This type of display adds the important dimension of elevation to the study of land use and environmental processes as observed in satellite images. The perspective view was created by draping a Landsat satellite image over an SRTM elevation model. Topography is exaggerated 1.5 times vertically. The Landsat image was provided by the United States Geological Survey's Earth Resources Observations Systems (EROS) Data Center, Sioux Falls, South Dakota.SRTM uses 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

    Water, sediments and water lily (Eichornia crassipes) from the Jose Antonio Alzate Dam were analyzed in order to determine concentrations of chromium, iron, nickel, copper, zinc, cadmium, lead and mercury. Mercury, lead, chromium and iron were found in concentrations above permissible limits in water, and in high concentrations in sediments. Cadmium, nickel, copper and zinc never were found in concentrations above permissible limits in water. The highest concentrations of heavy metals in water lily were found in the root. Accumulation factors decreased in the following order: Zn> Cr> Fe> Ni> Cu> Pb> Hg and Cd. Statistical differences ({alpha} < 0.5) between the collection samples dates was observed. High correlations between metals concentrations in superficial water, sediment and water hyacinth were also observed. These correlations could indicate that the heavy metals studied here, are originated from a natural source such as sediments or from an industrial source. (Author).

    2003-03-01

    SANS data from some standard samples have been obtained using BATAN-SANS instrument in Serpong. The experiments were performed for various experimental set-ups that involve different detector positions and collimator lengths. This paper describes the BATAN-SANS instrument briefly as well as the data taken from those experiments and followed with discussion of the results concerning the performance and calibration of the instrument. The standard samples utilized in these experiments include porous silica, polystyrene-poly isoprene, silver behenate, poly ball and polystyrene-poly (ethylene-alt-propylene). Even though the results show that BATAN-SANS instrument is in good shape, but rooms for improvements are still widely open especially for the velocity selector and its control system. (author)

    San Martin Tuxtla Volcano is located in the State of Veracruz, Eastern Mexico (18.572N, 95.169W, 1650 masl). Its last eruption, which occurred 1793, was described by D. Jose Moziño, a naturalist sent by the Viceroy-of the then New Spain-to report on the eruption. The activity lasted for several months with distinct events of explosive character, which produced thick ash fall deposits in its vicinity. The explosions were heard, among other places, in the coasts of Tampico some 500km NW from the volcano. The ash fall reached distances up to 200 Km from the crater and covered an area of about 112,000 Km2. Following the description of Moziño and the results of field studies we make a reconstruction of the eruption. We identified the air fall deposit from this eruption and present an isopach map. We present radiocarbon ages of the paleosoils under the ash bed as an indirect evidence of its age. This data together with present day wind velocities, and a diffusion-advection model of the dispersion of ashes allow to estimate in at least 10km the altitude reached by some of the eruptive plumes. An estimation of the minimum volume of ash erupted, based on the reconstructed isopachs, is of about 1.3 x 108 m3. Microphotographs of the ashes suggest that the activity was of phreatomagmatic and strombolian nature. Finally, we address some aspects of the volcanic risk in the area derived from our study.

  9. Toxic phytoplankton in San Francisco Bay

    1996-01-01

    The Regional Monitoring Program (RMP) was conceived and designed to document the changing distribution and effects of trace substances in San Francisco Bay, with focus on toxic contaminants that have become enriched by human inputs. However, coastal ecosystems like San Francisco Bay also have potential sources of naturally-produced toxic substances that can disrupt food webs and, under extreme circumstances, become threats to public health. The most prevalent source of natural toxins is from blooms of algal species that can synthesize metabolites that are toxic to invertebrates or vertebrates. Although San Francisco Bay is nutrient-rich, it has so far apparently been immune from the epidemic of harmful algal blooms in the world’s nutrient-enriched coastal waters. This absence of acute harmful blooms does not imply that San Francisco Bay has unique features that preclude toxic blooms. No sampling program has been implemented to document the occurrence of toxin-producing algae in San Francisco Bay, so it is difficult to judge the likelihood of such events in the future. This issue is directly relevant to the goals of RMP because harmful species of phytoplankton have the potential to disrupt ecosystem processes that support animal populations, cause severe illness or death in humans, and confound the outcomes of toxicity bioassays such as those included in the RMP. Our purpose here is to utilize existing data on the phytoplankton community of San Francisco Bay to provide a provisional statement about the occurrence, distribution, and potential threats of harmful algae in this Estuary.

    Nosocomial infections have become more important to the health system by the high costs of these, but are little data available about them in recent years. The clinical utility of the determination of serum galactomannan (GMS) in patients with high risk of contracting the infection by Aspergillus spp, was assessed, between January 2009 and December 2012 at the Hospital San Juan de Dios. Several existing studies in the scientific literature have already evaluated the clinical usefulness, specific data have been inexistent for Costa Rica or for Central America and the Caribbean; so it is important to have known whether the conduct of the test has been similar to the other populations or have specific variations [Spanish] Las enfermedades nosocomiales han cobrado mayor importancia para el sistema de salud por el gasto elevado que han representado, pero son pocos los datos disponibles respecto a ellas en los ultimos anos.

    Full text: Small angle scattering data while on an absolute scale and relatively accurate over large ranges of observables (0.003 -1 ; 0.1 -1 ) is often relatively featureless. I will address some of the problems this causes, and some of the ways of minimising these, by reference to our recent SANS results. For the benefit of newer chums this will involve discussion of the strengths and weaknesses of data from ISIS (LOQ), Argonne (SAND) and the I.L.L. (D22), and the consequences these have for modelling. The use of simple portable or remote access systems for modelling will be discussed - in particular the IGOR based NIST system of Dr. S. Kline and the VAX based FISH system of Dr. R. Heenan, ISIS. I will illustrate that a wide variety of physically appealing and complete models are now available. If you have reason to believe in a particular microstructure, this belief can now be either falsified, or the microstructure quantified, by fitting to the entire set of scattering patterns over the entire Q-range. For example, only in cases of drastic ignorance need we use only Guinier and Porod analyses, although these may provide useful initial guidance in the modelling. We now rarely need to use oversimplified logically incomplete models - such as spherical micelles with neglect of intermicellar correlation- now that we possess fast desktop/experimental computers

    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.

    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.

    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.

  11. 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. This mangrove is expanding and has low human impact thus far. Management actions should be taken to protect and preserve these important coastal ecosystems. Rev. Biol. Trop. 58 (Suppl. 3: 1-22.

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

    SANS (Small Angle Neutron Scattering) is a popular method for elucidation of nano-scale structures. However science continually challenges SANS for higher performance, prompting exploration of ever-more exotic and expensive technologies. We propose a compact high resolution SANS, using very cold neutrons, magnetic focusing lens and a wide-angle spherical detector. This system will compete with modern 40 m pinhole SANS in one tenth of the length, matching minimum Q, Q-resolution and dynamic range. It will also probe dynamics using the MIEZE method. Our prototype lens (a rotating permanent-magnet sextupole), focuses a pulsed neutron beam over 3-5 nm wavelength and has measured SANS from micelles and polymer blends. (authors)

    The extensive development of genealogical studies based on archival documents has provided powerful support for genetic research in Costa Rica over the past quarter century. As a result, several questions of population history have been answered, such as those involving hereditary illnesses, suggesting additional avenues and questions as well. Similarly, the preservation of massive amounts of historical documentation highlights the major advantages that the Costa Rican population offers to genetic research.

    Full Text Available Austin (1992 reported Eurema a. agave (Cramer 1775 to the Caribbean of Costa Rica. However, he actually had found E. a. millerorum, described by Bousquets & Luis-Martinez (1987 for the Caribbean of Mexico. The presence of Eurema a. agave is confirmed on this paper with information of specimens collected in the Pacific and Atlantic slopes of Costa Rica. Aspects on distribution of both subspecies are included.
