Arango Mejia, Maria Isabel; Zapata Garcia, Gilberto; Martens, Uwe

2012-01-01

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.

Rivera, A. L.

2016-12-01

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).

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.

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.

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

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

Treguear, T; Peters, L

1995-01-01

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

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.

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 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

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

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.

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

Application of GIS and Visualization Technology in the Regional-Scale Ground-Water Modeling of the Twentynine Palms and San Jose Areas, California

Science.gov (United States)

Li, Z.

2003-12-01

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

In-Situ Detection of SO2 Plumes in Costa Rica from Turrialba Volcano using Balloon-borne Sondes

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.

Orozco Rodriguez, Rafael; Munoz Hernandez, Roger

2012-01-01

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

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

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.

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.

Volcanic gas impacts on vegetation at Turrialba Volcano, Costa Rica

Science.gov (United States)

Teasdale, R.; Jenkins, M.; Pushnik, J.; Houpis, J. L.; Brown, D. L.

2010-12-01

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.

1998-01-01

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)

Observations of basin ground motions from a dense seismic array in San Jose, California

Science.gov (United States)

Frankel, A.; Carver, D.; Cranswick, E.; Bice, T.; Sell, R.; Hanson, S.

2001-01-01

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

Human chlamydiosis is a zoonotic disease of avian origin caused by Chlamydia psittaci. 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.

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

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.

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).

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

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.

Polio Crisis in Costa Rica: Lessons Learned and Achievements

Gioconda Vargas-Morúa

2015-05-01

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.

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.

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.

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.

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.

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.

Solar-energy-system performance evaluation update: San Anselmo School, San Jose, California, April 1982-June 1982

Kendall, P.W.

1982-01-01

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.

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.

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 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.

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.

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.

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

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.

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.

Full Text Available La costa rionegrina del golfo San Matías muestra un uso casi continuo, ca. 5000 años AP hasta el presente. 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.

The Jose f Gallery, located in the central Bohemia region of the Czech Republic (not far from the capital, Prague), was first excavated in 1981 as an exploration complex for the potential mining of gold. In 2007, the gallery was substantially reconstructed to house the Jose f Underground Educational Facility (Jose f UEF), which subsequently became an autonomous workplace under the direction of the Czech Technical University in Prague. At the beginning of 2010, the UEF was renamed the Jose f Regional Underground Research Centre (Jose f URC) which, along with the extensive underground complex, features modern above-ground facilities. One of the most important roles of this research centre is to provide practical -in situ- instruction in the fields of geotechnical engineering, geology, geochemistry, radiochemistry and radioecology. The training of future experts in this authentic underground setting involves the participation of several other Czech universities and numerous experienced specialists from outside the academic sphere. The IAEA has recently added the Jose f URC to its prestigious list of international training centres involved in the Training in and demonstration of waste disposal technologies in underground research facilities - A network of centres of excellence project.

Bowen, L

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.

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.

Martin, Jorge; Garcia, Piedad

1998-01-01

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.

2001-03-01

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)

Scorza, Andrea V; Duncan, Colleen; Miles, Laura; Lappin, Michael R

2011-12-29

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.

Decompression Induced Crystallization of Basaltic Andesite Magma: Constraints on the Eruption of Arenal Volcano, Costa Rica.

Science.gov (United States)

Szramek, L. A.; Gardner, J. E.; Larsen, J. F.

2004-12-01

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.

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.

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.

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.

The main findings of two high-level regional workshops organized in 2002 - by the International Petroleum Industry Environmental Conservation Association (IPIECA) in Kuala Lumpur, Malaysia, and by the Regional Association of Oil and Natural Gas Companies in Latin America and the Caribbean (ARPEL), IPIECA and UNEP in San Jose, Costa Rica - are presented in this article. The purpose of these workshops was to increase the understanding of regional development and climate change issues, and to identify opportunities for effective near- and long-term action, particularly through the Clean Development Mechanism (CDM). Economic, methodological and institutional barriers to private sector investment in CDM projects still exist. Uncertainties about rules surrounding the CDM have progressed from hypothetical concerns to more practical ones related to institutional capacity to review and approve project applications in a timely and cost-effective manner

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.

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

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.

This study included two Costa Rican families with members affected by Recessive Pigmentary Autosomic Retinitis (RPAR). The first family (C1) from the province of San Jose, has 10 alive affected members, and 14 obligatory carriers. They present an Early Appearance Degeneration, RPAR tipe1 (cane-cone). The author used polymorphic markers (STRPs) to discard some related regions, with the RP in the literature. He also used the Linkage program, for the analysis of ligaments. The second family (P1), proceeding from Acosta (situated in the province of Alajuela), has 13 alive affected members and 23 obligatory carriers and they present numerous consanguineous unions. This case is a RPAR with Early Appearance (Night Blindness, fat ERG), but with a shower degeneration. The author concludes that, with studies such as this one, there will be a capacity to offer RP molecular diagnostic, and also advance in its knowledge and treatment. (S. Grainger)

Temperature profiles from Pos Crater Lake

In 1984, we took part in an expedition to measure the temperature field and bathymetry of the acid lake (Figure 1) that has formed in the crater of Poás volcano, Costa Rica, since its last eruption in 1953. Obtaining these data was the first step in a long-range study planned by researchers at the Center for Geophysical Research, University of Costa Rica (San Jose, Costa Rica), and the College of Oceanography, Oregon State University (Corvallis). The study will eventually consider all aspects of fluid behavior in a volcanic lake that is heated or otherwise convectively driven by energy injected at the lake bottom.Evidence of convection is clearly visible on the surface of the Poás lake most of the time. Fumarole activity has been continuous since 1953. Phreatic explosions are quite frequent, varying from weak to strong, and the height of the ejected column varies from 1 to more than 500 m. One immediately useful result of the research would be an estimate of the heat transfer from sources within the conduit to the overlying water column. As far as geophysical fluid behavior goes, we are interested in the turbulent and diffusive processes by which heat and chemical species are transferred. We are especially interested in the impact on the density stratification of the density changes that occur as particulates settle downward through the fluid column. The stratification would otherwise be controlled by the turbulent and diffusive processes driven by thermochemical factors.

Orchid bees as bio-indicators for organic coffee farms in Costa Rica: does farm size affect their abundance?

Science.gov (United States)

Hedström, Ingemar; Denzel, Andrew; Owens, Gareth

2006-09-01

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.

Crustal Deformation along San Andreas Fault System revealed by GPS and Sentinel-1 InSAR

Xu, X.; Sandwell, D. T.

2017-12-01

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.

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)

Full Text Available Introduction: Postoperative pain remains as a problem. National studies report incidences of 31% for moderate and 22% for severe pain. Inadequate analgesia is related to dissatisfaction and adverse outcomes. The aim of this study was to describe the incidence and characteristics of the postoperative pain in the post-anesthesia care unit (PACU at Hospital Universitario San José of Popayán (HUSJ in patients undergoing general anesthesia during the first postoperative hour. Methods: Cohort study. We recruited patients attending PACU and undergoing procedures using general anesthesia, between 18 and 70 years. Using a standardized collection form medical history, demographic data, medical history, anesthetic management, intraoperative analgesia and postoperative pain assessment by verbal and numerical pain scale (1-10 were recorded. Postoperative outcome data were also collected in the PACU. Results: The incidence of severe postoperative pain at 10 minutes was 12.3% 95%CI [7.1-18.2] (19 patients. Within 30 minutes of assessment 4.5% 95%CI [1.3-8.4] (7 patients and 1.9% 60 minutes 95%CI [0-4.5] (3 patients. 48.7% required rescue analgesic at PACU. Incidence of postoperative nausea and vomiting (PONV was significantly different in patients requiring rescue analgesic. Conclusion: The incidence of severe postoperative pain in the first postoperative hour at HUSJ is close to 12% and it decreases as time goes by. Patients requiring rescue analgesic have a higher incidence of postoperative complications such as PONV.

[Distribution, surface and protected area of palm-swamps in Costa Rica and Nicaragua].

Science.gov (United States)

Serrano-Sandí, Juan; Bonilla-Murillo, Fabian; Sasa, Mahmood

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

Observations of volcanic plumes using small balloon soundings

Science.gov (United States)

Voemel, H.

2015-12-01

Eruptions of volcanoes are very difficult to predict and for practical purposes may occur at any time. Any observing system intending to observe volcanic eruptions has to be ready at any time. Due to transport time scales, emissions of large volcanic eruptions, in particular injections into the stratosphere, may be detected at locations far from the volcano within days to weeks after the eruption. These emissions may be observed using small balloon soundings at dedicated sites. Here we present observations of particles of the Icelandic Grimsvotn eruption at the Meteorological Observatory Lindenberg, Germany in the months following the eruption and observations of opportunity of other volcanic particle events. We also present observations of the emissions of SO2 from the Turrialba volcano at San Jose, Costa Rica. We argue that dedicated sites for routine observations of the clean and perturbed atmosphere using small sounding balloons are an important element in the detection and quantification of emissions from future volcanic eruptions.

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.

Currently, there are 35 active mines, 5 mills and 4 ion exchange plants in the Grants area. There was a general increase in uranium and vanadium with time over the San Jose and Puerco System. This doesn't appear to be related to any individual discharge but most likely reflects the general increase in activity in the area. As mining continues, this increase is expected to continue. The project reported here involved determining physical and chemical parameters of the water in the San Jose-Puerco system in New Mexico between March 1978 and September 1980. 14 refs

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

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.

Earth Systems Science Curriculum Choices for Pre-Service Teachers at San Jose State University

Science.gov (United States)

Messina, P.; Metzger, E. P.

2008-12-01

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

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

Science.gov (United States)

Tortini, R.; van Manen, S. M.; Burson, B.; Carn, S. A.

2014-12-01

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

Dentro de los hallazgos principales están que el Modelo de Altman calificó a cuatro de las cinco empresas anali- zadas como zona roja el año en que se declararon en quiebra, el Modelo de Ohlson, con su ecuación O1 u O3, calificó en quiebra las cinco empresas el año en que se dio, y el modelo de Beaver calificó como el año con peores indicadores al último en tres oca- siones, a diferencia de los otros modelos, los cuales no indicaron que el año de quiebra tuviera los peores indicadores.   Abstract    This article analyzes the models for company bankruptcy prevention used by the Costa Rican business sector. The author applied the studies models to the selected group of companies that had started the judicial intervention or bankruptcy process within the Bankruptcy Court of the Justice Court of San Jose. The objective was to determine if the selected models were capable to prevent the bankruptcy before it initialized. The primary fin- ding was an EM Score 4:5 analyzed companies in the red zone that had filed for bankruptcy within that year. The use of the O1 and O3 equations of the Ohlson method was to predict the bankruptcy of the five companies in the year that had filed to have a bankruptcy case. However, in the Beaver method the companies scored a three as the worst indicators of the year to file for bankruptcy yet the remaining company’s worst year was not the ability to file for bankruptcy within the time.

Full Text Available Resumo Este artigo apresenta a circulação do intelectual paranaense Lysimaco Ferreira da Costa nas discussões sobre os rumos da educação brasileira, em particular, sobre o ensino secundário, nas décadas de1920 e 1930, destacando as conexões e deslocamentos tecidos numa rede de relações, ou seja, suas vinculações com intelectuais de outros estados, em particular com os intelectuais paulistas e cariocas. Esse estudo constatou que a relação entre Lysimaco Ferreira da Costa e pessoas pertencentes ao grupo católico deu-se mais por questões políticas, do que por vias religiosas. Pelo que se apreende do estudo de sua sociabilidade, pode-se dizer que conservou, em seu círculo de amizades, católicos, protestantes e pessoas de crenças diversas, desde que essas não se opusessem, diante de circunstâncias de tomada de decisão e partido, aos seus interesses políticos. Palavras-chave: Lysimaco Ferreira da Costa; intelectuais da educação; ensino secundário.   LYSIMACO FERREIRA DA COSTA AND SECONDARYEDUCATION IN BRAZIL Abstract This article presents the insertion of Lysimaco Ferreira da Costa in the discussions concerning the direction of Brazilian education. He was an intellectual born in the state of Paraná. The period of the analysis ranges from 1920 and 1930 and its focus is the discussion of the secondary school. It emphasizes the ties and connections established in Lysimaco Ferreira da Costa’s network of relationships, his associations with intellectuals of other states, mainly from Rio de Janeiro and São Paulo. Through the data obtained in this study, it is possible to say that the affiliation between Lysimaco Ferreira da Costa and the Catholic group took place primarily due to political reasons rather than religious grounds. According to the study of his sociability, he maintained in his circle of friends both Catholics, Protestants and people of several beliefs, as long as they did not oppose to his political interests

Identification of Meloidogyne species associated with uptall ornamentals plants in Costa Rica

International Nuclear Information System (INIS)

Solano-Gonzalez, Stefany; Esquivel-Hernandez, Alejandro; Molina-Bravo, Ramon; Morera-Brenes, Bernal

2015-01-01

Nematodes species of the genus Meloidogyne associated with upland ornamental plants were identified. 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

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

2001-01-01

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.

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.

The Turrialba Volcano is a stratovolcano located approximately 35 km northwest from San Jose, Costa Rica's capital city. A series of eruptions since October 29, 2014 until at least late 2015, has represented the most significant activity of this volcano since the 1860s. A significant volume of ash was dispersed with this eruptions that reached the most populous areas of the country. The characteristics of the ash particles are analyzed in order to establish the nature of the eruptive events that occurred on 2014 and 2015, and to monitor the evolution of the eruptive processes. The analysis was carried out utilizing optical microscopy and stereomicroscopy techniques, as well as novel scanning electron microscopy (SEM) methods that involve imaging and element composition analysis by means of Energy Dispersive X-Ray Spectroscopy (EDX). The evolution of the Turrialba eruptions is showed from phreatic events in 2014, with ashes composed entirely of non-juvenile fragments, to phreatomagmatic events starting on March 12, 2015 with the appearance of a significant fraction of juvenile components in the ash.

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.

Geochronological synthesis of magmatism, metamorphism and metallogeny of Costa Rica, Central America

International Nuclear Information System (INIS)

Alvarado, Guillermo E.; Gans, Phillipe B.

2012-01-01

A comprehensive compilation of 651 (since 1968) radiometric ages determinations (415 40 Ar/ 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 (∼ 160 to ∼ 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 (∼ 71 Ma). However, voluminous subalkaline, primary volcanic rocks have appeared only after ∼ 29 Ma. Intrusive to hypabyssal granitic to gabboic plutons, stocks, equivalent dykes and sills, are widely exposed in the Talamanca range (∼ 12,4 - 7,8 Ma), hills of Escazu (∼ 6,0 - 5,9 Ma), and Fila Costena (∼ 18,3 - 16,8 and ∼ 14,8 - 11,1 Ma), Tapanti-Montes del Aguacate-Carpintera (∼ 4,2 - 2,2 Ma) and Guacimal (∼ 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 ∼ 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 front of the modern arc. This activity was followed by the

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 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.

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

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.

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)

2006-01-01

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

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.

A la costa de Luis A. Martínez: ¿la defensa de un proyecto liberal para Ecuador?

Directory of Open Access Journals (Sweden)

1998-01-01

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.

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

Andrade Marinho, E.V. de.

1985-09-01

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.

2012-03-01

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.

Compact High Resolution SANS using very cold neutrons (VCN-SANS)

International Nuclear Information System (INIS)

Kennedy, S.; Yamada, M.; Iwashita, Y.; Geltenbort, P.; Bleuel, M.; Shimizu, H.

2011-01-01

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)

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.

Decreased Odds of Injection Risk Behavior Associated With Direct Versus Indirect Use of Syringe Exchange: Evidence From Two California Cities.

Science.gov (United States)

Behrends, Czarina N; Li, Chin-Shang; Gibson, David R

2017-07-29

While there is substantial evidence that syringe exchange programs (SEPs) are effective in preventing HIV among people who inject drugs (PWID), nearly all the evidence comes from PWID who obtain syringes from an SEP directly. Much less is known about the benefits of secondary exchange to PWID who get syringes indirectly from friends or acquaintances who visit an SEP for them. We evaluated the effectiveness of direct versus indirect syringe exchange in reducing HIV-related high-risk injecting behavior among PWID in two separate studies conducted in Sacramento and San Jose, California, cities with quite different syringe exchange models. In both studies associations between direct and indirect syringe exchange and self-reported risk behavior were examined with multivariable logistic regression models. Study 1 assessed effects of a "satellite" home-delivery syringe exchange in Sacramento, while Study 2 evaluated a conventional fixed-site exchange in San Jose. Multivariable analyses revealed 95% and 69% reductions, respectively, in high-risk injection associated with direct use of the SEPs in Sacramento and San Jose, and a 46% reduction associated with indirect use of the SEP in Sacramento. Conclusions/Importance: The very large effect of direct SEP use in Sacramento was likely due in part to home delivery of sterile syringes. While more modest effects were associated with indirect use, such use nevertheless is valuable in reducing the risk of HIV transmission of PWID who are unable or unwilling to visit a syringe exchange.

Spent fuel characterization program in Jose Cabrera nuclear power plant

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.

Full Text Available La escalada de violencia en la que vive el estado occidental de Michoacán, México, desde 2006, ha afectado con especial virulencia a las regiones de la Tierra Caliente, la Sierra Costa y la Meseta Purépecha. En este artículo se abordan dos casos de comunidades indígenas, una purépecha: Cherán, y una nahua: San Miguel de Aquila. Se describen y comparan las respuestas de ambas ante los embates del crimen organizado, en busca de los elementos que expliquen los resultados dramáticamente distintos que han obtenido a partir de sus respectivas iniciativas de respuesta colectiva ante la violencia. El enfoque desde la ecología política permite analizar la problemática de ambos casos como resultado del «asalto global a los bienes comunes», mientras que las nociones de comunalidad y buen vivir resultan pertinentes para identificar las fortalezas, las debilidades y las posibles consecuencias a futuro de los movimientos sociales. COMMUNALITY AND BUEN VIVIR AS INDIGENOUS STRATEGIES TO FACE VIOLENCE IN MICHOACAN: THE CASES OF CHERÁN AND SAN MIGUEL DE AQUILA The escalation of violence experienced since 2006 in the Western state of Michoacan, Mexico, has significantly affected the regions of Tierra Caliente, Sierra Costa and Meseta Purépecha. This article addresses two cases of indigenous communities, a Purepecha community in Cherán, and a Nahua community in San Miguel de Aquila. The collective responses of these two communities to the attacks of organized crime are described and compared in search of elements to explain the dramatically different results obtained by both communities. An approach from the perspective of political ecology allows for an analysis of the issues faced by each one of them as a result of the «global assault on common goods». The notions of comunalidad and buen vivir ‘good living’ are germane to an identification of strengths, weaknesses and possible future consequences of the social movements.

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

Directory of Open Access Journals (Sweden)

Jing Li

2014-12-01

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

1973-04-01

172 men from the urban areas of Bogota and Cali, Colombia and 77 men from the urban area of San Jose, Costa Rica who had received vasectomies in 1971 were interviewed between January and March 1972 to determine characteristics of acceptors and their attitudes prior to and following the vasectomy. The men were between 30 and 44 years old, married, with an average of 5.7 children, mostly Roman Catholic (77.5%). 75.4% had completed primary school; 36.5% were specialized workers and craftsmen; 20.5% were unskilled or manual laborers. 41.8% learned about vasectomy through the mass media. Most men were satisfied with all aspects of the operation, convalescence, sexual and social relations after the vasectomy, and post emotional state and physical health. 98% said they would have the operation over again; 68.6% said the vasectomy had made a positive difference in their lives. When adequate information is available, some Latin American men do choose vasectomy (contradicting their stereotyped image of machismo and the presumed influence of the Catholic Church). Mass media and the influence of satisfied vasectomized males shape attitudes towards vasectomy in Latin America.

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.

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.

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

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.

'Around here I am the law!'
Strengthening police officers' compliance with the rule of law in Costa Rica

Directory of Open Access Journals (Sweden)

2006-12-01

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.

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

Asten, Michael W.; Boore, David M.

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

Full Text Available En este trabajo se describe el sistema de salud de Costa Rica, que presta servicios de salud, agua y saneamiento. El componente de servicios de salud incluye un sector público y uno privado. El sector público está dominado por la Caja Costarricense de Seguro Social (CCSS, institución autónoma encargada del financiamiento, compra y prestación de la mayoría de los servicios personales. La CCSS se financia con contribuciones de los afiliados, los empleadores y el Estado, y administra tres regímenes: el seguro de enfermedad y maternidad, el seguro de invalidez, vejez y muerte, y el régimen no contributivo. La CCSS presta servicios en sus propias instalaciones o contrata prestadores del sector privado con los que establece contratos denominados "compromisos de gestión". El sector privado comprende una amplia red de prestadores que ofrecen servicios ambulatorios y de especialidad con fines lucrativos. Estos servicios se financian sobre todo con pagos de bolsillo, pero también con primas de seguros privados. El Ministerio de Salud es el rector del sistema y como tal cumple con funciones de dirección política, regulación sanitaria, direccionamiento de la investigación y desarrollo tecnológico. Dentro de las innovaciones relativamente recientes que se han implantado en Costa Rica destacan la implantación de los equipos básicos de atención integral de salud (EBAIS, la desconcentración de los hospitales y clínicas públicos, la introducción de los acuerdos de gestión y la creación de las Juntas de Salud.This paper describes the Costa Rican health system which provides health, water and sanitation services.

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

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.

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

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

[The relationship between selected socioeconomic characteristics and fertility].

Araica, H

Until about a decade ago, the countries of the Central American isthmus had some of the highest population growth rates in the world due to a spectacular decline in mortality and continued high fertility. In the 1960s nonprofit organizations appeared which publicized the possibility of family planning in the hope of avoiding abortion and its sequelae. Financing from international and bilateral organizations enabled government family planning programs to distribute contraceptives, resulting in a demographic change induced from the exterior and skipping of some steps in the demographic transition. The passage to a more moderate level of fertility is observable in all the countries of the region to a greater or lesser degree and in varying magnitudes depending on social class and economic power. Information on differential fertility from the 1976 Costa Rica Fertility Survey suggests the course of development in the next few years in the other countries of Central America. Age of entry into first union averaged 19.0 years for the total sample of women aged 25-44; it was higher in urban areas and almost a year lower in most rural areas. Female educational level had a greater effect; age at 1st union was 18.2 for those with less than 3 years of education and 20.9 for those with over 10 years. Women with less than 3 years of education had a total of 6.6 children, while those with 6-10 years had 3.0 and those with over 10 years had 2.1. Women in the San Jose metropolitan area had 3.3 children, and women in the most rural areas had 5.4. Currently working women had 3.6 children and those who had never worked had 4.7 children. 83.0% of the total sample in metropolitan San Jose, 75.0% in urban areas outside the central valley, and 74.6% in rural areas outside the central valley used contraception. 68.5% with less than 3 years of education but 82.2% with over 10 years used contraception. 81.6% currently working but 79.0% who had never worked used some method.

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

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

Energy Technology Data Exchange (ETDEWEB)

Mendis, M.; Park, W.; Sabadell, A.; Talib, A.

1982-04-01

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

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.

Trejo Barajas, Dení

2006-12-01

Full Text Available This article analyzes the importance acquired during the Independence war by the maritime trade coming from other Central and South American ports and operating through the San Blas port. The antecedents of the colonial commerce are studied, as well as the British presence and the consequences of the free trade measures taken by the Spanish government which particularly affected the Nueva Galicia Intendencia and the Pacific coasts of Nueva España. In the end, this highly polemical traffic permitted by the Spanish authorities strengthened Nueva Galicia both politically and economically, and prefigured the regionalism that was to be characteristical in 19^th Century Mexico.

En este artículo se analiza la importancia que adquirió, durante la guerra de Independencia, el comercio marítimo por el puerto de San Blas procedente de Panamá y otros puertos centro y sudamericanos. Se exponen los antecedentes relativos a la crisis del comercio colonial, la presencia inglesa y los efectos de las medidas de libre comercio adoptadas por el gobierno español que afectaron de manera particular a la intendencia de Nueva Galicia y las costas del Pacífico novohispano. Se revisan las consecuencias de este polémico tráfico permitido por las autoridades hispanas y que desembocó en el fortalecimiento político y económico de la Nueva Galicia, prefigurando el regionalismo característico del siglo XIX mexicano.

Full Text Available Objetivo: Realizar una primera aproximación a los determinantes de la utilización de consultas médicas en Costa Rica. Método: Los datos proceden de la Encuesta Nacional de Salud para Costa Rica 2006. En el análisis econométrico se utilizó un modelo binomial negativo estándar ligado al enfoque de producción de salud de Grossman y un modelo en dos partes congruente con el enfoque agente-principal. Resultados: Los factores determinantes de la utilización de consultas médicas fueron el nivel educativo, el estado de salud percibida, el número de enfermedades crónicas declaradas y la región de residencia. Conclusiones: El hecho de que las variables de necesidad de salud expliquen de forma significativa la probabilidad de contacto con las consultas médicas y que, además, no se registren diferencias significativas de utilización entre quintiles de ingreso y situación de seguro, es un resultado esperable y deseable en un sistema público solidario y casi universal como el costarricense. No se obtienen resultados concluyentes de la influencia del médico en la frecuencia de utilización de las consultas que postula el modelo de agente-principal.Objective: To analyze the determinants of health care utilization (visits to the doctor in Costa Rica using an econometric approach. Methods: Data were drawn from the National Survey of Health for Costa Rica 2006. We modeled the Grossman approach to the demand for health services by using a standard negative binomial regression, and used a hurdle model for the principal-agent specification. Results: The factors determining healthcare utilization were level of education, self-assessed health, number of declared chronic diseases and geographic region of residence. Conclusion: The number of outpatient visits to the doctor depends on the proxies for medical need, but we found no multivariate association between the use of outpatient visits and income or insurance status.

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

Science.gov (United States)

Lücke, O. H.; Linkimer, L.

2013-12-01

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

Pura Vida: Teacher Experiences in a Science Education Study Abroad Course in Costa Rica

Medina, Stephanie Rae

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

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.

San Marino.

1985-02-01

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

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.

Management commitments and primary care: another lesson from Costa Rica for the world?

Soors, Werner; De Paepe, Pierre; Unger, Jean-Pierre

2014-01-01

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

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

International Nuclear Information System (INIS)

Mora, Patricia

2003-01-01

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

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

2016-04-01

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

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.

Characterising the spatial dynamics of sympatric Aedes aegypti and Aedes albopictus populations in the Philippines

Directory of Open Access Journals (Sweden)

Jennifer Duncombe

2013-11-01

Full Text Available Entomological surveillance and control are essential to the management of dengue fever (DF. Hence, understanding the spatial and temporal patterns of DF vectors, Aedes (Stegomyia aegypti (L. and Ae. (Stegomyia albopictus (Skuse, is paramount. In the Philippines, resources are limited and entomological surveillance and control are generally commenced during epidemics, when transmission is difficult to control. Recent improvements in spatial epidemiological tools and methods offer opportunities to explore more efficient DF surveillance and control solutions: however, there are few examples in the literature from resource-poor settings. The objectives of this study were to: (i explore spatial patterns of Aedes populations and (ii predict areas of high and low vector density to inform DF control in San Jose village, Muntinlupa city, Philippines. Fortnightly, adult female Aedes mosquitoes were collected from 50 double-sticky ovitraps (SOs located in San Jose village for the period June-November 2011. Spatial clustering analysis was performed to identify high and low density clusters of Ae. aegypti and Ae. albopictus mosquitoes. Spatial autocorrelation was assessed by examination of semivariograms, and ordinary kriging was undertaken to create a smoothed surface of predicted vector density in the study area. Our results show that both Ae. aegypti and Ae. albopictus were present in San Jose village during the study period. However, one Aedes species was dominant in a given geographic area at a time, suggesting differing habitat preferences and interspecies competition between vectors. Density maps provide information to direct entomological control activities and advocate the development of geographically enhanced surveillance and control systems to improve DF management in the Philippines.

Theater and the Discourse on Power: Jose Rizal’s Participation in Philippine Theater in the Last Decades of the Nineteenth Century

Directory of Open Access Journals (Sweden)

Apolonio B. Chua

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

“Uncovering the Kink Celebrating my Black Identity: Perceptions on Afro-Costa Ricans Natural Hair”

2016-05-01

Full Text Available It is no secret the racism within the Costa Rican society especially against people of African descent. While this racism is manifested in mostly overt ways it is nonetheless present, and continues to affect people of African descent in a myriad of ways including how they feel about their natural hair. From a very early age Afro-Costa Rican children learn to look down on their natural kink reinforced verbally and through images designed for them to hide, and dislike what is naturally theirs. As a result many embraced synthetic, and other ethnic group’s natural hair, preferring to pay any amount of money besides undergoing significant hair, and scalp ill-treatment all with the objective of hiding the natural kink. The main objective of this paper is to make visible the perceptions of Afro-Costa Ricans natural hair by both Afro, and mestizo ethnic groups, and enquire about some of the effects on people of African descent in Costa Rica. The exploratory research collected data from four focus groups of teenage mestizos, 20th century newspaper, one workshop, and questionnaires filled only by Afro-Costa Ricans.

To evaluate the efficacy of a sodium fluoride (NaF)/silica/xylitol dentifrice compared with that of a positive control NaF/silica dentifrice on caries increments in school children over a 3-year period in an area without an optimal level of fluoride in the drinking water (mean level schools in the San Jose, Costa Rica metropolitan area. Clinical dental examinations were performed at participating schools utilizing portable dental equipment. Caries evaluations employed conventional tactile/visual methodology consisting of artificial light, dental mirrors and single-edge #23 explorers. Children accepted into the study were stratified by age and sex into two balanced groups within each school, and randomly assigned to use either a positive control dentifrice containing 0.243% NaF/silica or a test dentifrice containing 0.234% NaF/silica/10% xylitol. Children were instructed to brush with the assigned dentifrice twice daily. Caries evaluations were conducted at baseline, 2 years, and 3 years. After 3 years, subjects using the 0.234% NaF/silica/10% xylitol dentifrice had statistically significantly reduced decayed/filled surfaces (DFS; -12.3% reduction; P < or = 0.001) and decayed/filled buccal and lingual surfaces (DFS-BL; -10.5% reduction; P < or = 0/01).

Extraction of resins from WD-22 tank in Jose Cabrera Nuclear Power Plant

International Nuclear Information System (INIS)

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)

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

1988-01-01

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)

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

Science.gov (United States)

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

2005-05-01

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

2012-01-01

Full Text Available Schwannomas are benign peripheral nerve sheath neoplasms composed almost entirely of Schwann cells and are diagnosed histopathologically by the presence of singular architectural patterns called Antoni A and Antoni B areas. These were described first in 1920 by the Swedish neurologist Nils Antoni. The Antoni A tissue is highly cellular and made up of palisades of Schwann cell nuclei, a pattern first described in 1910 by the Uruguayan neuro-pathologist Jose Verocay and are known as Verocay bodies. This article describes the structure and appearance of Verocay bodies and Antoni A and B areas with a brief biographical introduction of the men who described these patterns.

Benefit-cost assessment programs: Costa Rica case study

1991-01-01

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

A case for historic joint rupture of the San Andreas and San Jacinto faults.

Science.gov (United States)

Lozos, Julian C

2016-03-01

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 and historic observations for the ~M7.5 earthquake of 8 December 1812 are best explained by a rupture that begins on the San Jacinto fault and propagates onto the San Andreas fault. This precedent carries the implications that similar joint ruptures are possible in the future and that the San Jacinto fault plays a more significant role in seismic hazard in southern California than previously considered. My work also shows how physics-based modeling can be used for interpreting paleoseismic data sets and understanding prehistoric fault behavior.

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

Science.gov (United States)

Swiecki, Z.; Schwartz, S. Y.

2010-12-01

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

Wastewater and Saltwater: Studying the Biogeochemistry and Microbial Activity Associated with Wastewater Inputs to San Francisco Bay

Nitrification is the process of converting ammonium (NH­­4+) into nitrate (NO3-), and is a crucial step in removing nitrogen (N) from aquatic ecosystems. This process is governed by ammonia-oxidizing bacteria (AOB) and archaea (AOA) that utilize the ammonia monooxygenase gene (amoA). Studying the rates of nitrification and the abundances of ammonia-oxidizing microorganisms in south San Francisco Bay's Artesian Slough, which receives treated effluent from the massive San Jose-Santa Clara Regional Wastewater Facility, are important for understanding the cycling of nutrients in this small but complex estuary. Wastewater inputs can have negative environmental impacts, such as the release of nitrous oxide, a byproduct of nitrification and a powerful greenhouse gas. Nutrient inputs can also increase productivity and sometimes lead to oxygen depletion. Assessing the relative abundance and diversity of AOA and AOB, along with measuring nitrification rates gives vital information about the biology and biogeochemistry of this important N-cycling process. To calculate nitrification rates, water samples were spiked with 15N-labeled ammonium and incubated in triplicate for 24 hours. Four time-points were extracted across the incubation and the "denitrifier" method was used to measure the isotopic ratio of nitrate in the samples over time. In order to determine relative ratios of AOB to AOA, DNA was extracted from water samples and used in clade-specific amoA PCR assays. Nitrification rates were detectable in all locations sampled and were higher than in other regions of the bay, as were concentrations of nitrate and ammonium. Rates were highest in the regions of Artesian Slough most directly affected by wastewater effluent. AOB vastly outnumbered AOA, which is consistent with other studies showing that AOB prefer high nutrient environments. AOB diversity includes clades of Nitrosospira and Nitrosomonas prevalent in estuarine settings. Many of the sequenced genes are related

A survey on Triatoma dimidiata in an urban area of the province of Heredia, Costa Rica

Directory of Open Access Journals (Sweden)

Rodrigo Zeledón

2005-10-01

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.

2018-03-01

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.

The 1793 Eruption of San Martin Volcano (Los Tuxtlas, Veracruz, Mexico)

Science.gov (United States)

Espindola, J. M.; Zamora-Camacho, A.; Godinez, M. L.; Rodriguez-Elizarraras, S.

2007-12-01

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.

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

Full Text Available Se realizó un estudio del estado de la biotecnología en Costa Rica como parte del proyecto "SIMBIOSIS: Programa Cooperativo para la Construcción de Indicadores en Biotecnología adaptados a los países de América Latina y el Caribe, para motivar la aplicación y transferencia de tecnologías industriales". El estudio se enfocó en dos ítemes: "investigadores" y "proyectos de investigación", desarrollados en Costa Rica entre 1998 y 2002. Se construyó una base de datos a partir de la cual se obtuvieron indicadores para los investigadores, relacionados con aspectos como género, edad, desempeño como docentes, número de proyectos, funciones, grado académico, área de especialidad y número de publicaciones. Los indicadores determinados para los proyectos de investigación se vinculan con los temas de: especialidades, sector socioecónomico de aplicación, duración y número de investigadores por proyecto. Entre las principales conclusiones obtenidas a nivel nacional cabe mencionar la alta participación de las mujeres en esta área de investigación (54%; la baja participación de recursos humanos jóvenes como investigadores (13% menores de 30 años, y que la mayoría de los investigadores, con altos grados académicos, tienen 4 o más proyectos a su cargo (42%. Con relación a las especialidades de los proyectos, la mayoría se clasifican en la categoría Bio-Agro (39% mientras que en Acuicultura sólo se encontró un 1% del total. Los sectores de aplicación con el mayor número de proyectos son: Agropecuario (37% y Salud Humana (35%.

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

Cifuentes, N.; Hernandez Bravo, B.

2013-01-01

The dismantling phase of the Jose Cabrera nuclear power plant required a system able to manage the spent nuclear fuel produced during its activity: The individualized temporary storage. This project, which is pioneer in Spain, apart from being technically and securely friendly with the standards, should agree with sustainability standards. That is the reason why, while the technical project was being developed, Gas Natural Fenosa Engineering worked up an environmental impact assessment. This study, made by a multidisiciplimary team, analyzed all the interactions between the project and its environment, and allowed the inclusion of environmental measures that were required to reduce the negative effects and guarantee the environmental viability of the project.

Since 1984, the Seismic Network of the Volcanological and Seismological Observatory of Costa Rica, Universidad Nacional (OVSICORI-UNA) has been recording and registering the seismicity in Costa Rica. Before September 2012, the earthquakes registered by this seismic network in northwestern Costa Rica were moderate to small, except the Cóbano earthquake of March 25, 1990, 13:23, Mw 7.3, lat. 9.648, long. 84.913, depth 20 km; a subduction quake at the entrance of the Gulf of Nicoya and generated peak intensities in the range of MM = VIII near the epicentral area and VI-VII in the Central Valley of Costa Rica. Six years before the installation of the seismic network, OVSICORI-UNA registered two subduction earthquakes in northwestern Costa Rica, specifically on August 23, 1978, at 00:38:32 and 00:50:29 with magnitudes Mw 7.0 (HRVD), Ms 7.0 (ISC) and depths of 58 and 69 km, respectively (EHB Bulletin). On September 5, 2012, at 14:42:02.8 UTC, the seismic network OVSICORI-UNA registered another large subduction earthquake in Nicoya peninsula, northwestern Costa Rica, located 29 km south of Samara, with a depth of 21 km and magnitude Mw 7.6, lat. 9.6392, long. 85.6167. This earthquake was caused by the subduction of the Cocos plate under the Caribbean plate in northwestern Costa Rica. This earthquake was felt throughout the country and also in much of Nicaragua. The instrumental intensity map for the Nicoya earthquake indicates that the earthquake was felt with an intensity of VII-VIII in the Puntarenas and Nicoya Peninsulas, in an area between Liberia, Cañas, Puntarenas, Cabo Blanco, Carrillo, Garza, Sardinal, and Tamarindo in Guanacaste; Nicoya city being the place where the maximum reported intensity of VIII is most notable. An intensity of VIII indicates that damage estimates are moderate to severe, and intensity VII indicates that damage estimates are moderate. According to the National Emergency Commission of Costa Rica, 371 affected communities were reported; most

Seventy-two gravity cores were collected by the U.S. Geological Survey in 1990, 1991, and 2000 from San Pablo Bay and Carquinez Strait, California. The gravity cores collected within San Pablo Bay contain bioturbated laminated silts and sandy clays, whole and broken bivalve shells (mostly mussels), fossil tube structures, and fine-grained plant or wood fragments. Gravity cores from the channel wall of Carquinez Strait east of San Pablo Bay consist of sand and clay layers, whole and broken bivalve shells (less than in San Pablo Bay), trace fossil tubes, and minute fragments of plant material.

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