    The Republic of Costa Rica is one of the most stable and strongest countries in Central America. It is bordered by Nicaragua and Panama to the north and south and the Caribbean Sea and the Pacific ocean to the east and west and has a total land size slightly smaller than West Virginia. Costa Ricans enjoy a high life expectancy and literacy rate. As well, schools have an attendance rate of nearly 100%. The predominant ethnic group is white, and the predominant spoken language is Spanish. The work force is divided up as follows: 32% agriculture, 25% industry and commerce, 38% services and government, and 5% finance and banking. The country's climate is tropical and subtropical, and the geography of Costa Rica is composed of rugged terrain, mountains, large forest areas, some lowlands and 3 volcanic mountain ranges. The great majority of Costa Ricans are of European descent with only small numbers of the indigenous Indian population surviving today. The government of Costa Rica is democratic, holding periodic elections. The electoral process is monitored by the Supreme Electoral Tribunal. Other bodies of government include the Supreme Court of Justice and the Legislative Assembly. The National Liberation Party has been in power since 1948 and represents socialist ideals. Many factors such as: an influx of enlightened leaders and officials, flexible class lines, economic prosperity and the absence of military force have allowed Costa Rica to progress and maintain a stable economy and government amidst an unstable region. Costa Rica's relations with other countries and international organizations are excellent. PMID:12177991

    2014-01-01

    INTRODUCTION: The treatment strategy for appendiceal mass is controversial, ranging from operation or image-guided drainage to conservative treatment with or without antibiotics. The aim of this study was to assess the various treatment modalities with respect to complications and treatment failure...... in total 3,772 patients. Operation for appendiceal mass was beset with a moderate to high risk of complications of up to 57% and a risk of intestinal resection of up to 25%. Major complications were observed in up to 18% of cases. Conservative treatment with or without antibiotics was associated...... with a treatment failure rate of 8-15%. Drainage was beset with a risk of complications of 2-15% and a risk of treatment failure of 2-13%. CONCLUSION: Operation with appendectomy for appendiceal mass carries a high risk of complications compared with conservative treatment or drainage. Drainage may lower the risk...

    Full Text Available Appendiceal diverticulosis is a rare condition. Herein reported is a case of appendiceal diverticulosis and diverticulitis clinically masquerading as appendiceal carcinoma. A 62-year-old woman presented with abdominal pain. US and CT showed a tumor measuring 5 × 4 × 4 cm in vermiform appendix. Colon endoscopy showed mucosal elevation and irregularity in the orifice of vermiform appendix. A biopsy of the appendiceal mucosa showed no significant changes. Clinical diagnosis was appendiceal carcinoma and wide excision of terminal ileum, appendix, cecum, and ascending colon was performed. Grossly, the appendix showed a tumor measuring 5 × 3 × 4 cm. The appendiceal lumen was opened, and the appendiceal mucosa was elevated and irregular. The periappendiceal tissue showed thickening. Microscopically, the lesion was multiple appendiceal diverticula. The diverticula were penetrating the muscle layer. The mucosa showed erosions in places. Much fibrosis, abscess formations, and lymphocytic infiltration were seen in the subserosa. Abscesses were also seen in the diverticular lumens. Some diverticula penetrated into the subserosa. The pathologic diagnosis was appendiceal diverticulitis. When they encounter an appendiceal mass, clinicians should consider appendiceal diverticulitis as a differential diagnosis.

  11. Appendiceal mucocoeles and pseudomyxoma peritonei

    Institute of Scientific and Technical Information of China (English)

    Anupam Dixit; John HP Robertson; Satvinder S Mudan; Charles Akle

    2007-01-01

    Mucocoele of the appendix occurs when obstruction of the appendiceal lumen results in mucus accumulation and consequent abnormal dilatation. The most important aetiology, from a surgical perspective, is either mucinous cystadenoma or cystadenocarcinoma. In the latter, a spontaneous or iatrogenic rupture of the mucocoele can lead to mucinous intraperitoneal ascites, a syndrome known as pseudomyxoma peritonei. Optimal management of mucoceles is achieved through accurate preoperative identification and subsequent careful resection. We report two cases and subsequently discuss the clinical presentation of mucocoeles, their association with pseudomyxoma peritonei and an optimal management of both conditions.

    2007-01-01

    San Jose, capital city of Costa Rica, fills the valley between two steep mountain ranges. In this image made from data collected by the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) instrument on NASA's Terra satellite, visible, shortwave, and near-infrared wavelengths of light that the sensor observed have been combined to produce a false-color version of the scene in which vegetation is red, urban areas are silvery gray, water is dark blue, and clouds are white. The image was captured on February 8, 2007. San Jose is in the center of the image. The Rio Torres winds through downtown San Jose. Cartago, the much smaller colonial capital, sits in the lower right corner, while the city of Alajuela appears across the river, northwest of San Jose. The cities' manmade surfaces contrast sharply with the lushly vegetated landscape surrounding the city. Greenhouses are common in the region, and their glass roofs may be the brilliant white spots around the outer edges the cities. The long, straight runway of the Tobias Bolanos International Airport is visible as a dark line southeast of Alajuela. The landscape around the two cities shown here is rugged. Steep mountain peaks cast dark shadows across their leeward slopes. Patches of dark red vegetation on the mountains north of San Jose may be rainforest. Coffee plantations also cover the slopes of the mountains around the city. February is the dry season in Costa Rica. During the rainy season, from about April to November, clouds usually block the satellite's view of this tropical location.

    Ultrasound and CT are the dominant imaging modalities for assessment of suspected pediatric appendicitis, and the most commonly applied diagnostic criterion for both modalities is appendiceal diameter. The classically described cut-off diameter for the diagnosis of appendicitis is 6 mm when using either imaging modality. To demonstrate the fallacy of using the same cut-off diameter for both CT and US in the diagnosis of appendicitis. We conducted a retrospective review of patients younger than 18 years who underwent both US and CT of the appendix within 24 h. The shortest transverse dimension of the appendix was measured at the level of the proximal, mid and distal appendix on US and CT images. We compared mean absolute difference in appendiceal diameter between US and CT, using the paired t-test. We reviewed exams of 155 children (58.7% female) with a mean age of 11.3 ± 4.2 years; 38 of the children (24.5%) were diagnosed with appendicitis. The average time interval between US and CT was 7.0 ± 5.4 h. Mean appendiceal diameter measured by CT was significantly larger than that measured by US in cases without appendicitis (5.3 ± 1.0 mm vs. 4.7 ± 1.1 mm, P < 0.0001) and in cases with appendicitis (8.3 ± 2.2 mm vs. 7.0 ± 2.0 mm, P < 0.0001). Mean absolute diameter difference at any location along the appendix was 1.3-1.4 mm in normal appendices and 2 mm in cases of appendicitis. Measured appendiceal diameter differs between US and CT by 1-2 mm, calling into question use of the same diameter cut-off (6 mm) for both modalities for the diagnosis of appendicitis. (orig.)

    Varekamp, J. C.; Haynes, A.; Balcom, P. H.

    2012-12-01

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

    Despite increasing average real family incomes in Costa Rica in the late 1990s and early 2000s, poverty rates did not fall. In this paper, we argue that during this period economic growth in Costa Rica did not translate into reduced poverty because of changes in family structure and in the labor market, and that these changes had an important gender dimension. Specifically, an increase in the proportion of Costa Rican households headed by single mothers led to an increase in the number of wom...

  5. Pleural mesothelioma in Costa Rica

    International Nuclear Information System (INIS)

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

    2003-08-01

    The classification of appendiceal mucinous tumors is controversial and terminology used for them inconsistent, particularly when they lack overtly malignant features but are associated with extra-appendiceal spread. We reviewed 107 appendiceal mucinous neoplasms and classified them as low-grade appendiceal mucinous neoplasm (LAMN) (n = 88), mucinous adenocarcinomas (MACAs) (n = 16), or discordant (n = 3) based on architectural and cytologic features. LAMNs were characterized by a villous or flat proliferation of mucinous epithelium with low-grade atypia. Thirty-nine tumors were confined to the appendix, but 49 had extra-appendiceal tumor spread, including 39 with peritoneal tumor characterized by mucin pools harboring low-grade mucinous epithelium, usually dissecting in a hyalinized stroma. Eight of the 16 MACAs lacked destructive invasion of the appendiceal wall and eight showed an infiltrative pattern of invasion. Extra-appendiceal tumor spread was present in 12 MACAs (four peritoneum, seven peritoneum and ovaries; one ovaries only). In MACAs with an infiltrative pattern, peritoneal tumor consisted of glands and single cells in a desmoplastic stroma. The peritoneal tumor in the remaining cases consisted of mucin pools that contained mucinous epithelium with high-grade atypia and, in some cases, increased cellularity compared with that seen in peritoneal spread in cases of LAMN. Three cases were classified as discordant because the appendiceal tumors were LAMNs but the peritoneal tumors were high-grade. Follow-up was available for 49 LAMNs, 15 MACAs, and 2 discordant cases. None of the patients with LAMNs confined to the appendix experienced recurrence (median follow-up 6 years). LAMNs with extra-appendiceal spread were associated with 3-, 5-, and 10-year survival rates of 100%, 86%, and 45%, respectively. Patients with MACA had 3- and 5-year survival rates of 90% and 44%, respectively (p = 0.04). The bulk of peritoneal disease correlated with prognosis among

  15. Bladder metastases of appendiceal mucinous adenocarcinoma: a case presentation

    International Nuclear Information System (INIS)

    Appendiceal adenocarcinoma is rare with a frequency of 0.08% of all surgically removed appendices. Few cases of appendiceal carcinoma infiltrating the bladder wall for spatial contiguity have been documented. A case is reported of a 45-years old woman with mucinous cystadenocarcinoma of the appendix with bladder metastasis. Although ultrasonography and voided urinary cytology were negative, abdomen computed tomography (CT) scan and cystoscopy and subsequent pathological examination revealed a mass exclusively located in the anterior wall of the bladder. Histopathology of the transurethral bladder resection revealed a bladder adenocarcinoma [6 cm (at the maximum diameter) × 2,5 cm; approximate weight: 10 gr] with focal mucinous aspects penetrating the muscle and perivisceral fat. Laparotomy evidenced the presence of a solid mass of the appendix (2,5 cm × 3 cm × 2 cm) extending to the loco-regional lymph nodes. Appendectomy and right hemicolectomy, linfoadenectomy and partial cystectomy were performed. The subsequent pathological examination revealed a mucinous cystadenocarcinoma of the appendix with metastatic cells colonising the anterior bladder wall and several colic lymph nodes. The rarity of the appendiceal carcinoma invading the urinary bladder and its usual involvement of nearest organs and the posterior bladder wall, led us to describe this case which demonstrates the ability of the appendiceal cancer to metastasize different regions of urinary bladder

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

  4. Conferences on electronic waste in Costa Rica

    International Nuclear Information System (INIS)

    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

    Aydin Özgür

    2007-05-01

    Full Text Available Abstract Background Appendiceal parasites can cause symptoms of appendiceal pain, independent of microscopic evidence of acute inflammation. The diagnosis of a parasitic infestation is generally achieved only after the pathologic examination of the resected appendices. Patients/Methods Pathology department records were reviewed for all patients who required an operation for symptoms of acute appendicitis between 2000 and 2006. The specimens which were pathologically diagnosed to contain parasites were reevaluated for features of acute inflamation, and parasite type. The medical records were reviewed in detail to achieve a diagnostic score(Eskelinen. Radiologic imaging findings were correlated, if present. Results Of the 190 appendectomies performed, 6 specimens (3,15% were found to contain parasites(4 Enterobius vermicularis, 2 Taenia subspecies. Appendectomies with Taenia showed acute inflamation, while acute inflamation was absent in the ones with Enterobius vermicularis. The Eskelinen score was higher than the treshold in two cases with an acute inflamation, and in two without. Ultrasound scans, and a computed tomography scan were performed in 5 patients. In 3 of 4 bland appendices, results favored acute appendicitis. Conclusion The diagnosis of gastrointestinal parasites is not only made by examining the stool but the diagnosis can be made by histology from surgical specimens. Timely diagnosis and appropriate therapy might prevent probable future complications that may necessitate surgical procedures, at least in some of the patients. The clinical management of these infections is different from that for classical appendicitis.

    Full Text Available During a very brief visit to Costa Rica at the end of March 1991, we took the opportunity to see if we could find signs of Lutra longicaudis. Spraints were used to survey for otters. In Costa Rica logging continues but there is an excellent system of national parks where otter populations might be maintained. A full field survey is urgently required combined with awareness programmes in the parks, and Costa Rica is small enough for this to be practical.

    Studying tourism planning means understanding and assuming that tourism is not just a flux of tourists who move without leaving a trace, but a motor that physically transforms the territory due to the need to build infrastructure and tourist accommodation like hotels, second homes, attractions etc, which have contributed to major changes in previously untouched territories. Among them, the Costa Smeralda resort represents the most iconic and best known tourist destination of Sardinia. In...

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

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

    Full Text Available Abstract Introduction Appendiceal duplication is a rare anomaly that can manifest as right lower quadrant pain. There are several variations described for this condition. We recommend aggressive operative management should this anatomical variation present in the presence of acute appendicitis. Case presentation We report the case of a 15-year-old African American girl who presented to our hospital with right lower quadrant pain and was subsequently found to have appendiceal duplication. Conclusion There are two categorical systems that have described and stratified appendiceal duplication. Both classification systems have been outlined and referenced in this case report. A computed tomography scan has been included to provide a visual aid to help identify true vermiform appendiceal duplication. The presence of this anatomical abnormality is not a reason for surgical intervention; however, should this be found in the setting of acute appendicitis, aggressive resection of both appendices is mandatory.

    Neoplasms of the appendix are rare, but because of their unusual presentation and unpredictable biologic behavior, it is important to diagnose them correctly. Mucinous tumors account for 58 % of malignant tumors of appendix in SEER database and the remaining are carcinoids. The mucinous appendiceal tumors have a potential to spread to the peritoneum and viscera in the form of gelatinous material with or without neoplastic cells resulting in Pseudomyxoma peritonei. (PMP) PMP is a clinical entity that has a unique biological behavior and can arise from seemingly benign tumors to frankly malignant ones. Several classifications exist for PMP of which Ronnet's classification has been the most popular. In 2010, the WHO proposed a 2 tier classification that classified PMP as either low grade or high grade based on the presence of mucin, cytological and architectural features. According to this classification when the underlying cause for PMP is an appendiceal tumor it is always a mucinous adenocarcinoma rather than a mucocoele or adenoma and these terms should no longer be used. This system of classification helps in predicting the behavior of the tumor and proper treatment strategies. The understanding of the pathogenesis of the disease has also improved with identification of newer biomarkers and molecular genetic alterations. IHC markers CK 20, CDX2 and MUC2 are found to be positive in these tumors in addition to KRAS mutation and loss of heterozygosity in some gene loci. Proper histopathologic classification and predicting the tumor behavior requires a close interaction between the pathologist and the surgeon. The use of the combined modality treatment of cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) has led to a 5-year survival ranging from 62.5 % to 100 % for low grade, and 0 %-65 % for high grade disease. This article focuses on the etiopathogenesis, clinical behavior, diagnosis and classification of mucinous tumors of the

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

Por último, se postula que el reciente estancamiento en las tasas de período puede ser una consecuencia de los cambios en el tempo de construcción de la familia, con mujeres de baja paridez que postergan los nacimientos, lo que contrarresta las tendencias de descenso que generan las mujeres de mayor paridez quienes aún pueden estar restringiendo su reproducción.ABSTRACTThis paper uses data from the Latin American Comparative Fertility Surveys as well as from the World Fertility Survey to study trends and differentials in birthspacing among ever married women in Costa Rica during the period 1945-1974. A good deal of attention is placed on the pace of fertility in threshold, early and late stages of the fertility decline that this country experienced during the sixties and early seventies. The results show a good deal of similarity in the tempo of reproduction across parities and geographical areas.However, an analysis of the background variables affecting birthspacing shows differences between urban and rural zones. Finally, it is postulated that the recent plateau in period rates may be a consequence of changes in the tempo of

    Full Text Available In modern times, radar is used in a wide variety of applications including defense, air traffic control, meteorology, and even mapping. Radio Detection and Ranging (RADAR involves the nterpretation of a signal to determine characteristics of targets. With the unavoidable presence of various types of interference, signalprocessing is naturally an important part of any radar system. In this paper, we used a series of 8 bit costas sequence [2], each pulse having a length of 5 microseconds. The interpulse period was 200 microseconds and the radar return receive window started 20 icroseconds after pulse transmission and ended 170 microseconds later. The radar system sampling rate and carrier frequency were 10MHz (2x over sampling and 5GHz respectively. The noise was Gaussian and had a standard deviation of 2 relative to the signal amplitude. With these parameters detectable targets lay in between 3.7 km to 29.0 km away, and moved with a speed under 53 m/s.

    Full Text Available El presente artículo cita los nombres, ordenados por su principal acción plaguicida, de poco más de un centenar de plantas con algún tipo de potencial bioplaguicida en Costa Rica. Posteriormente se presenta la situación de la oferta y la demanda actual de estos productos, destacando las principales limitaciones que experimenta su desarrollo comercial, así como el potencial que posee el país en esta materia, basado en su extraordinaria biodiversidad. Además, se hace mención de las entidades involucradas en esta temática. Finalmente se hacen algunas consideraciones adicionales relacionadas con la toxicidad de estos productos y sobre la importancia de los conocimientos etnobotánicos en esta materia. Entre las especies de plantas que más se mencionan en la bibliografía consultada están Allium sativum, Annona reticulata, Azadirachta indica, Capsicum frutescens, Chenopodium Ambrosiodes, Gliricidia sepium, Quassia amara y Ryania speciosa. Se resalta el hecho de que hasta la fecha, tanto su uso artesanal como su desarrollo comercial son mínimos, en relación con el potencial existente en el país. Con excepción de dos productos, los pocos bioplaguicidas de origen vegetal que se comercializan son importados.

  18. Assessment of mammography in Costa Rica

    International Nuclear Information System (INIS)

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

  4. Chronic appendicitis and complete appendiceal invagination: UC, CT and MRI findings

    International Nuclear Information System (INIS)

    The appendiceal intussusception is a rare entity. Usually there is a predisposing factor such as a tumor, mucocele, etc. We report the case of a 61 years old female patient, with recurrent abdominal pain, localized in the right lower quadrant. We performed different diagnostic imaging exams including: double-contrast barium enema, enteroclysis, ultrasonography, computed tomography and magnetic resonance. After endoscopy a surgical procedure removed the appendix. The pathological anatomy confirmed the diagnosis of an appendiceal intussusception, complicated with a chronic inflammatory process. Appendiceal intussusception and chronic appendicitis are infrequent; it is even more uncommon the association of both entities. In addition, it was not found a predisposing cause to intussusception. For the reasons described above, we conclude that this case is an unusual presentation of appendiceal intussusception, not previously reported. (author)

    Full Text Available In early-modern Europe, historiography was often deployed as a political means for addressing internal issues. An example of such a history text written with a local agenda in mind is the tract Ragionamento sopra la triegua de' Paesi Bassi by Giovanni Costa, which was published in 1610 in Genoa. Taking the actual case of the Twelve Years' Truce during the period of the Dutch Revolt, Costa discusses in fact the internal affairs of Genoa, a Ligurian city-state functioning as satellite state of the Spanish Habsburg Empire. This article is centered on the question of why Costa opted for such an abstract and remote topic for this politico-economic backdrop, and also addresses the matter of his intended readership.

  15. Evaluation of severe accident risks, Peach Bottom, Unit 2: Appendices

    International Nuclear Information System (INIS)

    In support of the Nuclear Regulatory Commission's (NRC's) assessment of the risk from severe accidents at commercial nuclear power plants in the US reported in NUREG-1150, the Severe Accident Risk Reduction Program (SARRP) has completed a revised calculation of the risk to the general public from severe accidents at the Peach Bottom Atomic Power Station, Unit 2. This power plant, located in southeastern Pennsylvania, is operated by the Philadelphia Electric Company. The emphasis in this risk analysis was not on determining a ''so-called'' point estimate of risk. Rather, it was to determine the distribution of risk, and to discover the uncertainties that account for the breadth of this distribution. Off-site risk initiated by events both internal and external to the power station were assessed. This document provides Appendices A through E which include the following topics respectively: accident progression event tree; supporting information for the source term analysis; supporting information for the consequence analysis; risk results; and sampling information. 6 figs., 6 tabs

    1980-01-01

    The programmatic environmental analysis is an initial assessment of Ocean Thermal Energy Conversion (OTEC) technology considering development, demonstration and commercialization. It is concluded that the OTEC development program should continue because the development, demonstration, and commercialization on a single-plant deployment basis should not present significant environmental impacts. However, several areas within the OTEC program require further investigation in order to assess the potential for environmental impacts from OTEC operation, particularly in large-scale deployments and in defining alternatives to closed-cycle biofouling control: (1) Larger-scale deployments of OTEC clusters or parks require further investigations in order to assess optimal platform siting distances necessary to minimize adverse environmental impacts. (2) The deployment and operation of the preoperational platform (OTEC-1) and future demonstration platforms must be carefully monitored to refine environmental assessment predictions, and to provide design modifications which may mitigate or reduce environmental impacts for larger-scale operations. These platforms will provide a valuable opportunity to fully evaluate the intake and discharge configurations, biofouling control methods, and both short-term and long-term environmental effects associated with platform operations. (3) Successful development of OTEC technology to use the maximal resource capabilities and to minimize environmental effects will require a concerted environmental management program, encompassing many different disciplines and environmental specialties. This volume contains these appendices: Appendix A -- Deployment Scenario; Appendix B -- OTEC Regional Characterization; and Appendix C -- Impact and Related Calculations.

    2007-05-01

    From the NW extreme to the SW end of Costa Rica's volcanic backbone, a number of laterally collapsed volcanoes can be observed. Due to several factors, attention has been given to active volcanoes disregarding the importance of collapsed features in terms of assessing volcanic hazards for future generations around inhabited volcanoes. In several cases the typical horseshoe shape amphitheater-like depression can be easily observed. In other cases due to erosion, vegetation, topography, seismic activity or drastic weather such characteristics are not easily recognized. In the order mentioned above appear: Orosi-Cacao, Miravalles, Platanar, Congo, Von Frantzius, Cacho Negro and Turrialba volcanoes. Due to limited studies on these structures it is unknown if sector collapse occurred in one or several phases. Furthermore, in the few studied cases no evidence has been found to relate collapses to actual eruptive episodes. Detailed studies on the deposits and materials composing dome-like shapes will shed light on unsolved questions about petrological and chemical composition. Volume, form and distance traveled by deposits are part of the questions surrounding most of these collapsed volcanoes. Although most of these mentioned structures are extinct, at least Irazú volcano (active volcano) has faced partial lateral collapses recently. It did presented strombolian activity in the early 60s. Collapse scars show on the NW flank show important mass removal in historic and prehistoric times. Moreover, in 1994 a minor hydrothermal explosion provoked the weakening of a deeply altered wall that holds a crater lake (150m diameter, 2.6x106 ). A poster will depict images of the collapsed volcanoes named above with mayor descriptive characteristics. It will also focus on the importance of deeper studies to assess the collapse potential of Irazú volcano with related consequences. Finally, this initiative will invite researchers interested in such topic to join future studies in

  19. Maps of ultraviolet radiation in Costa Rica

    International Nuclear Information System (INIS)

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

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

    Fast, David E.

    1991-05-01

    This document consists of the appendices for annual report DOE/BP/39461--9 which is summarized as follows. The population of Yakima River spring chinook salmon (Oncorhynchus tschawytscha) has been drastically reduced from historic levels reported to be as high as 250,000 adults (Smoker 1956). This reduction is the result of a series of problems including mainstem Columbia dams, dams within the Yakima itself, severely reduced flows due to irrigation diversions, outmigrant loss in irrigation canals, increased thermal and sediment loading, and overfishing. Despite these problems, the return of spring chinook to the Yakima River has continued at levels ranging from 854 to 9,442 adults since 1958. In October 1982, the Bonneville Power Administration contracted the Yakima Indian Nation to develop methods to increase production of spring chinook in the Yakima system. The Yakima Nation's current enhancement policy attempts to maintain the genetic integrity of the spring chinook stock native to the Yakima Basin. Relatively small numbers of hatchery fish have been released into the basin in past years. The goal of this study was to develop data that will be used to present management alternatives for Yakima River spring chinook. A major objective of this study is to determine the distribution, abundance and survival of wild Yakima River spring chinook. The second major objective of this study is to determine the relative effectiveness of different methods of hatchery supplementation. The last three major objectives of the study are to locate and define areas in the watershed that may be used for the rearing of spring chinook; to define strategies for enhancing natural production of spring chinook in the Yakima River; and to determine the physical and biological limitations on production within the system.

    Prior to interpreting PET/CT, it is crucial to understand the normal biodistribution of fluorodeoxyglucose (FDG). It is also important to realize that the normal biodistribution can vary between adults and children. Although many studies have defined normal patterns of pediatric FDG uptake in structures like the thymus, brown fat and bone marrow, patterns of normal pediatric bowel activity, specifically uptake within the appendix, have not been well described. Active lymphoid tissue has increased FDG uptake when compared with inactive tissue. Since children have more active lymphoid tissue than adults, and because the appendix contains aggregated lymphoid tissue, we postulated that appendiceal uptake may be increased in pediatric patients. To define the normal level of appendiceal FDG activity in children by evaluating a series of consecutive FDG PET/CT scans performed for other indications. After obtaining IRB approval, we retrospectively reviewed 128 consecutive whole-body pediatric FDG PET/CT examinations obtained for a variety of clinical indications. CT scans on which the appendix could not be visualized were excluded from analysis. CT scans on which the appendix could be visualized were evaluated for underlying appendiceal pathology. Studies with appendiceal or periappendiceal pathology by CT criteria were excluded. A region of interest (ROI) was placed over a portion of each appendix and appendiceal maximum standardized uptake value (SUVmax) was calculated. If an adjacent loop of bowel activity interfered with accurate measurements of the appendix SUVmax, the scan was excluded from the analysis. A chart review was performed on patients with elevated appendiceal SUVmax values to ensure that the patients did not have clinical symptomatology suggestive of acute appendicitis. When the appendix or a portion of the appendix could be visualized and accurately measured, the SUVmax was determined. SUVmax of the appendix was compared to the SUVmax of normal liver and

    Appendiceal mucocele is a rare cause of acute abdomen. Mucinous appendiceal neoplasms represent 0.2–0.7% of all appendix specimens. The aim of this study is to report a case of a mucinous appendiceal neoplasm presented as acute appendicitis, discussing the clinical and surgical approach in the emergency setting. A 72-year-old female patient was admitted to the emergency department with a clinical examination indicative of acute abdomen. The patient underwent abdominal computed tomography scan which revealed a cystic lesion in the right iliac fossa measuring 8.3 × 5.2 × 4.1 cm, with calcified walls, and a mean density indicative of high protein content. The patient was taken to the operating room and a right hemicolectomy was performed. The postoperative course was unremarkable. The histopathological examination revealed a low-grade mucinous appendiceal neoplasm with negative regional lymph nodes. Ultrasound and CT are useful in diagnosing appendiceal mucocele and synchronous cancers in the emergency setting. The initial operation should include appendectomy and resection of the appendicular mesenteric fat along with any fluid collection for cytologic examination. During urgent appendectomy it is important to consider every mucocele as malignant in order to avoid iatrogenic perforation causing pseudomyxoma peritonei. Although laparotomy is recommended, the laparoscopic approach is not contraindicated. PMID:27066284

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

  2. Sonographic study about differential diagnosis between acute appendicitis and non-appendicitis in appendices of borderline diameter

    International Nuclear Information System (INIS)

    To find out the sonographic criteria which can be effectively used to differentiate acute appendicitis from non-appendicitis in patients with appendices with borderline diameter(5-8 mm). Sixteen patients diagnosed as acute appendicitis, another 16 patients diagnosed as non-appendicitis were included in this study. They complained of RLQ pain and their appendices measured 5-8 mm in diameter on sonogram. Features such as appendiceal wall thickness, presence or absence of air in appendiceal lumen, movability of tip of the appendix, compressibility of the appendix were evaluated on gray-scale sonogram and thereafter, presence or absence of color flow in the wall of the appendix was evaluated on color Doppler sonogram. Thickness of appendiceal wall is 2.98 ± 0.77 mm in acute appendicitis group and 1.73 ± 0.44 mm in non-appendicitis group (p<0.05). When 2.5 mm thickness of appendiceal wall is applied for diagnosis of acute appendicitis, sensitivity is 81.3%, specificity is 87.5% and accuracy is 84.4%. With absence of air in appendiceal lumen, sensitivity is 93.8%, specificity is 68.8% and accuracy is 81.3%. With absence of movability of appendiceal tip, sensitivity is 87.5%, specificity is 50% and accuracy is 68.8%. With absence of compressibility of the appendix, sensitivity is 100%, specificity is 31.3% and accuracy is 65.6%. With color flow in appendiceal wall, sensitivity is 81.3%, specificity is 62.5% and accuracy is 71.9%. The above mentioned criteria show statistically significant difference between acute appendicitis and non-appendicitis groups (p<0.05). When the diameter of the appendix measures 5-8 mm on sonogram, evaluation of thickness of appendiceal wall, air in appendiceal lumen, movability of tip, compressibility and color flow in the wall will be helpful to diagnose the acute appendicitis with confidence.

  14. Health without wealth? Costa Rica's health system under economic crisis.

    Science.gov (United States)

    Morgan, L M

    1987-01-01

    The recent history of Costa Rica's health system is reviewed, emphasizing the health-related effects of the economic crisis of the 1980s. This economic crisis has stopped and in some instances reversed the marked health improvements Costa Rica realized during the decade of the 1970s. The effects of the economic crisis emerge in 4 areas: deterioration in health status, as poverty contributed to higher disease rates; reductions in the government's ability to maintain public health and medical services; increased reliance on foreign aid to finance the health system; and growing national debate over the role of the state in health care. The result of the economic crisis was a reduction in health services and a questioning of the Costa Rican health model. This occurred following the implementation of an expensive health infrastructure and at a time when people most needed health services. During the 1941-70 period, domestic initiative can account for much of the expansion of Costa Rica's social security system, but also at this time international agencies such as the US Agency for International Development (USAID) and the Inter-American Development began to assist in the expansion of the health system. In 1971 a plan was initiated to create a nationalized health system. By 1980 the success of the health sector reorganization was evident in the statistics: marked improvements in life expectancy, infant mortality, and infectious disease mortality had surpassed the goals set by the Pan American Health Organization (PAHO) and the Ministry of Health. Costa Rica's success was a vindication of both policy goals and funding priorities, for it has been "proved" that primary health care was capable of improving health indices, particularly where the agencies had the active and conscientious support of the national government. By 1977, foreign contracts for aid had expired, and the Ministry declared that the rural health program would be supported totally by the government. The

    Salemis, Nikolaos S.; Nakos, Georgios; Katikaridis, Ilias; Zografidis, Andreas

    2016-01-01

    Appendiceal mucocele (AM) is a rare clinical entity comprising 8% of all appendiceal tumors, and it is seen in 0.2-0.3% of all appendectomy specimens. Apart from sporadic cases, there are no enough published data about the incidence of synchronous appendiceal tumors in patients with colorectal cancer. We describe a very rare case of synchronous occurrence of AM, colon adenocarcinoma, and tubulovillous adenoma of the rectum and review the relevant literature. We conclude that thorough preoperative and perioperative evaluations are mandatory in patients undergoing surgery for colorectal cancer to exclude a synchronous colon or an appendiceal primary tumor. Larger prospective studies are necessary to accurately determine the incidence of synchronous appendiceal tumors and colorectal cancer. PMID:27433069

    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.

    Full Text Available Abstract Introduction Although both appendiceal tumor and intestinal endometriosis have been reported as rare causes of abdominal pain, the coexistence of appendiceal mucinous neoplasm and ileal endometriosis has not previously been reported. Case presentation A 41-year-old Japanese woman presented with a positive fecal occult blood test and a 3-year history of menstruation-related lower abdominal pain. A colonoscopy demonstrated extrinsic compression of the cecum, suggesting a mass arising from the appendix or adjacent structures. Abdominal imaging showed a 6-cm cystic mass with intraluminal thick fluids originating from the appendix. At ileocecal resection for an appendiceal tumor, a 2-cm mass in the terminal ileum was incidentally found, which was included in the surgical specimen. Microscopic examination confirmed a diagnosis of a mucinous neoplasm of the appendix with endometriosis of the terminal ileum. Conclusions To avoid urgent surgery for subsequent serious events associated with disease progression, appendiceal tumor and intestinal endometriosis should be ruled out in patients with chronic abdominal pain.

    Appendicular abscess occurred in 14.2% of patients presenting acute appendicitis. Management of these patients remains controversial, ranging from an emergency appendectomy to a nonoperative treatment. On board French nuclear submarines, the usual treatment for all cases of appendiceal masses, including both appendicitis and appendiceal abscess, is an appendectomy. In the past 5 years, the introduction of ultrasonography (US) on board has enabled the diagnosis of appendiceal abscess with a high rate of accuracy, and the latest studies show that nonoperative treatment is an alternative approach. This nonsurgical treatment, based on intravenous administration of antibiotics, is successful in about 93% of the patients. Failure of nonsurgical treatment is a reliable indication of percutaneous drainage. The proportion of adult patients who need percutaneous drainage of abscesses is about 27%. A successful primary nonoperative treatment may or may not be followed by interval appendectomy at the conclusion of the patrol. Nonsurgical treatment is associated with a significantly lower morbidity than surgery. Considering that the on-board surgical facility is limited, nonsurgical treatment appears to be the best approach for treating a sailor with an appendiceal abscess during a submarine patrol mission.

  5. Extra-appendiceal findings in pediatric abdominal CT for suspected appendicitis

    International Nuclear Information System (INIS)

    Much has been written regarding the incidence, types, importance and management of abdominal CT incidental findings in adults, but there is a paucity of literature on incidental findings in children. We sought to determine the prevalence and characteristics of extra-appendiceal and incidental findings in pediatric abdominal CT performed for suspected appendicitis. A retrospective review was performed of abdominal CT for suspected appendicitis in a pediatric emergency department from July 2010 to June 2012. Extra-appendiceal findings were recorded. Any subsequent imaging was noted. Extra-appendiceal findings were divided into incidental findings of doubtful clinical significance, alternative diagnostic findings potentially providing a diagnosis other than appendicitis explaining the symptoms, and incidental findings that were abnormalities requiring clinical correlation and sometimes requiring further evaluation but not likely related to the patient symptoms. One hundred sixty-five children had abdominal CT for suspected appendicitis. Seventy-seven extra-appendiceal findings were found in 57 (34.5%) patients. Most findings (64 of 77) were discovered in children who did not have appendicitis. Forty-one of these findings (53%) could potentially help explain the patient's symptoms, while 30 of the findings (39%) were abnormalities that were unlikely to be related to the symptoms but required clinical correlation and sometimes further work-up. Six of the findings (8%) had doubtful or no clinical significance. Extra-appendiceal findings are common in children who undergo abdominal CT in the setting of suspected appendicitis. A significant percentage of these patients have findings that help explain their symptoms. Knowledge of the types and prevalence of these findings may help radiologists in the planning and interpretation of CT examinations in this patient population. (orig.)

    Full Text Available BackgroundThe value of immunohistochemistry (IHC-microarray analysis of pathological specimens in the management of patients is controversial although preliminary data suggests potential benefit. We describe the characteristics of patients undergoing a commercially available IHC-microarray method in patients with peritoneal metastases (PM and the feasibility of this technique in this population.MethodsWe retrospectively analyzed consecutive patients with pathologically confirmed PM from appendiceal or colorectal primary who underwent Caris Molecular IntelligenceTM testing. IHC, microarray, FISH and mutational analysis were included and stratified by PCI score, histology and treatment characteristics. Statistical analysis was performed using non-parametric tests.ResultsOur study included 5 patients with appendiceal and 11 with colorectal PM. The median age of patients was 51 (IQR 39-65 years, with 11(68% female. The median PCI score of the patients was 17(IQR 10-25. Hyperthermic intra-peritoneal chemoperfusion (HIPEC was performed in 4 (80% patients with appendiceal primary tumors and 4 (36% with colorectal primary. KRAS mutations were encountered in 40% of appendiceal vs. 30% colorectal tumors, while BRAF mutations were seen in 40% of colorectal PM and none of the patients with appendiceal PM (p=0.06. IHC biomarker expression was not significantly different between the two primaries. Sufficient tumor for microarray analysis was found in 44% (n=7 patients, which was not associated with previous use of chemotherapy (p>0.20 for 5-FU/LV, Irinotecan and Oxaliplatin.ConclusionsIn a small sample of patients with peritoneal metastases, the feasibility and results of IHC-microarray staining based on a commercially available test is reported. The apparent high incidence of the BRAF mutation in patients with PM may potentially offer opportunities for novel therapeutics and suggest that IHC-microarray is a method that can be used in this population.

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

    Science.gov (United States)

    Campo-Engelstein, Lisa; Meagher, Karen

    2011-08-01

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

    The geostrophic circulation between the Costa Rica Dome and Central America is described from CTD observations collected in two surveys: (a) The Wet Cruise in September-October 1993, and the Jet Cruise in February-March 1994. Poleward coastal flow was present on both occasions, but the transition from flow around the dome to the poleward Costa Rica Coastal Current flow was quite tortuous because of the presence of mesoscale eddies. In particular, a warm anticyclonic eddy was found off the Gulf of Fonseca during both cruises, at an almost identical position and with similar dimensions (150 m deep, 250 km in diameter) and surface speed (0.5 m s -1). In the Gulf of Panama, poleward flow was also observed, weaker in February-March 1994 than in September-October 1993, when it penetrated to 600 m depth and transported 8.5 Sv. In September-October 1993, the current between the dome and the coast was mostly ˜100 m deep and weak (˜0.15 m s -1), although in its southern side it was deeper (˜450 m) and faster at 0.3 m s -1. The poleward transport between the dome and the coast was ˜7 Sv. In February-March 1994 the Costa Rica Dome was a closed ring adjacent to the continental shelf, ˜500 km in diameter, at least 400 m deep, had geostrophic surface speeds ˜0.25 m s -1, and subsurface maximum speed (0.15-0.20 m s -1) at ˜180 m depth; the associated uplift of the isotherms was ˜150 m. The flow in the south part of the dome splits into two branches, the weakest one going around the dome and the strongest one continuing east and turning south before reaching the Gulf of Panama.

    Although appendiceal anatomical anomalies are very rare, understanding of the anatomical details of these anomalies is important for surgery. In this case report, we present images from multi-detector row computed tomography (MDCT) and histological findings of a rare anatomical appendiceal anomaly originating from the cecum and opening into the terminal ileum like a bridge. These anatomical details were clearly depicted on MDCT with multi-planar reconstruction. MDCT demonstrated a communication between the appendix and terminal ileum. Histological analysis revealed that a normal mucosal layer was maintained from the appendix to the connected ileum, without any evidence of inflammatory or neoplastic changes, and only thickening of the muscular layer of the appendix was identified. Based on these histological findings, the appendix was considered to represent an anatomical anomaly rather than secondary fistula caused by inflammation or neoplasm, which has not yet been reported.

    The gastrointestinal tract is the most common site for extranodal involvement by non-Hodgkin’s lymphoma. However, primary appendiceal lymphomas presenting as perforated acute appendicitis are very rare: they occur in only 0.015% of all gastrointestinal lymphoma cases. The management of this condition is still controversial, and a multimodality approach (e.g., surgery, radiation therapy, and chemotherapy) is the optimal treatment. In these cases, appendiceal non-Hodgkin’s lymphomas typically m...

  19. Is colour Doppler sonography a good method to differentiate normal and abnormal appendices in children?

    International Nuclear Information System (INIS)

    Aim: To determine whether colour Doppler sonograms can be used to differentiate between the normal appendix and acute appendicitis. Material and methods: This prospective study examined 50 consecutive children with suspected appendicitis using grey-scale and colour Doppler US. Appendicitis was diagnosed when the appendix diameter was greater than 6 mm. Blood flow on the appendiceal wall was measured and classified as non-existent (0 pixels), low (1-2), moderate (3-4) or abundant (>4). Likelihood ratios were calculated for each of these levels. The diagnosis of acute appendicitis was confirmed by pathological findings, and ruled out by clinical follow-up or pathological findings. Results: Of the 50 patients examined, 24 had appendicitis and 26 had a normal appendix. For 25 of the patients with a normal appendix, appendicitis was ruled out by clinical follow-up, and for one patient, by pathological findings. The abnormal appendix was identified in all patients with appendicitis. In the group of 26 patients without appendicitis, the normal appendix was visualized in 23 cases, one of which was false positive (100% sensitivity, 96% specificity). Abnormal appendices showed moderate to abundant flow in 62% of the cases and non-existent or low flow in 38%. Normal appendices had non-existent or low flow in 82% of the cases, but moderate or abundant in 18%. Significant differences were only found when the number of pixels was >4. Conclusion: Although the vascularity of normal and inflamed appendices may be different, this difference was not a good diagnostic indicator of appendicitis

Se encontró un total de 15 especies de corales (11 hermatípicas y 4 ahermatípicas, las que sumadas a informes previos para el parque hacen un total de 18 especies. El coral Porites lobata presentó la mayor cobertura coralina (36.5 ± 3.7% y fue el único presente en todos los sitios. Las otras especies de coral presentaron bajas coberturas (<10% y sólo fueron observadas en pocos sitios. El porcentaje de coral muerto fue de 1.8 ± 0.6% y el porcentaje de blanqueamiento (0.7 ± 0.2% está dado por P. lobata en un solo sitio. El PNMB y la Isla del Caño poseen el mayor número de especies de coral (18 especies de la región sur de Costa Rica; sin embargo, difieren en su composición. La baja diversidad y la baja cobertura coralina de varios sitios del parque se atribuyen al impacto del fenómeno de El Niño en los últimos años, a la sedimentación y a la dilución de las aguas en época de lluvias. Se sugiere la necesidad de realizar un monitoreo a largo plazo sobre estos ecosistemas y determinar futuras estrategias de manejo y conservación.

  2. Usefulness of measurement of the outer appendiceal diameter on abdominal computer tomography in the diagnosis of acute appendicitis

    International Nuclear Information System (INIS)

    The purpose of this study was to evaluate the accuracy of our computer tomography (CT)-based protocol and the usefulness of measurement of the outer appendiceal diameter on CT in the diagnosis of acute appendicitis. Two-hundred thirty-nine consecutive patients with clinical diagnoses of acute appendicitis during the period from January 2002 to Jun 2004 were evaluated. The CT criterion of acute appendicitis was the outer appendiceal diameter of 6 mm or more, and/or other associated inflammatory changes. The histological criterion of acute appendicitis was the presentation of polymorphic granulocytes throughout the appendiceal wall. Of 239 patients, 235 underwent CT examination. Among 222 patients with appendectomy, 205 had histologically proven acute appendicitis. Of 200 patients who had the outer appendiceal diameter of 6 mm or more on CT, 193 had histologically proven acute appendicitis. The positive predictive value for diagnosing acute appendicitis was 92.3% in the surgery group, and 96.5% in the group that the outer appendiceal diameter was 6 mm or more on CT. The recurrence rate of acute appendicitis diagnosed by CT following conservative therapy was 35.3%, and was high (50%) in the group with the appendiceal diameter of at least 10 mm. CT is useful in the diagnosis for acute appendicitis. (author)

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

  4. Enamel lesions in development, classification in Costa Rican families

    International Nuclear Information System (INIS)

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

    A survey of the contamination of the physical environment of Costa Rica with banned organochlorine pesticides (OCPs) relied on sampling air and soil at 23 stations acrossthe country in 2004. Average annual air concentrations, determined with XAD-based passive samplers, and surface soil concentrations were generally low when compared to values reported for North and Central America, which is consistent with relatively low historical domestic use and little atmospheric inflow from neighboring countries. Statistical analysis and concentration maps reveal three types of spatial distribution: alpha-hexachlorocyclohexane and p,p'-DDD had a relatively uniform distribution across the country; other DDT-related species were greatly elevated over the national average at Manuel Antonio, a National Park on the Pacific coast; and dieldrin, lindane, and chlordane-related species had higher concentrations in Costa Rica's populated Central Valley. An altitudinal transect of stations in the Central Valley shows declining air-soil concentration ratios with elevation for lindane, likely driven by atmospheric inversions and soil organic carbon content. Enantiomeric composition of chiral OCPs in air and soil was close to racemic, with slight depletion of (-)-alpha-HCH, (-)-cis-chlordane, and (+)-trans-chlordane. Estimated air-soil fugacity fractions are highly uncertain but indicate equilibrium conditions for most OCPs, net volatilization of lindane at some sites, and net deposition for p,p'-DDE. The study demonstrates an approach for quickly evaluating the spatial distribution of OCPs in an understudied area, identifying regionally important contaminants and areas of elevated concentrations.

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

  7. Greenhouse gas emissions from the coffee industry in Costa Rica

    1998-04-01

    Within the framework of a Joint implementation project ECN and the University of Heredia, department of chemistry (Laboratorio de Quimica de la Atmosfera LAQUAT) performed measurements to assess the emission of greenhouse gasses from the wastewater treatment facilities used by the coffee industry in Costa Rica. Wastewater from the coffee industry caused severe water pollution in the rivers of Costa Rica. In order to abate this problem wastewater treatment is now compulsory. The Chemical Oxygen Demand (COD) levels of the wastewater that is released into the river systems, must be below 1.5 kg COD per fanega (1 fanega is about 400 kg of coffee berries). Waste water can be treated using anaerobic lagoons. In these lagoons microbial activity will degrade the organic material and methane and carbon dioxide will be formed. These gasses escape to the atmosphere and contribute to the greenhouse effect. Within the joint implementation program, the Dutch government provided the extra money to install anaerobic reactor systems that replace the lagoons. In the reactor the methane that is formed is trapped and used for heating. The net effect is that methane emissions are converted to carbon dioxide emissions. This has a positive impact on the net emission levels since 1 kg of methane as effective as 21 kg of carbon dioxide in the greenhouse forcing. In order to estimate the real emission reduction obtained by the joint implementation program, measurements were carried out at a lagoon in San Isidro at the beneficio EI General, which is operated by Volcafe

    1998-10-01

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

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

  15. Evolution of industrial sector electricity demand in Costa Rica

    International Nuclear Information System (INIS)

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

    Treguear, T; Peters, L

    1995-01-01

    In San Jose, Costa Rica, the nongovernmental organization PROCAL has established two rescue homes for sexually abused girls 10-15 years of age. One of these homes is devoted to the care of pregnant girls. In almost all cases, the perpetrator was a male relative. Since girls are taught they must obey older male relatives, they are powerless to stop the abuse. When girls become pregnant as a result of sexual abuse, they face social ostracism and are blamed for their participation in sexual activity. PROCAL counsels the girls that they are victims of their own lack of power and provides them with skills and education they need to return to society and start a new life. The stories of two young girls who became pregnant as a result of sexual abuse and were helped by PROCAL are presented. PMID:12319363

    Full Text Available En este documento se elaboran y evalúan medidas alternativas de núcleo inflacionario para Costa Rica. La idea fundamental contempla al núcleo inflacionario como un indicador de la tendencia subyacente de la inflación capaz de capturar el componente del cambio total de precios común a todos los bienes y servicios, cuya persistencia se mantendría en el mediano y largo plazo y que excluye los cambios en los precios relativos de estos. La medida de núcleo inflacionario seleccionada se contrasta con el Índice de Núcleo Inflacionario (INI, indicador de inflación subyacente actualmente utilizado por el Banco Central de Costa Rica (BCCR.El Índice Subyacente de Inflación (ISI, definido como una medida de núcleo inflacionario que excluye un 30,7% del peso total del Índice de Precios al Consumidor (IPC, refleja más fielmente la tendencia subyacente de la inflación y logra capturar el movimiento más permanente del nivel general de precios, aislando las variaciones en precios relativos. Además, el ISI es fácil de calcular e interpretar lo cual ayuda a incrementar la transparencia y credibilidad de la política monetaria. También es un indicador oportuno, aumentando su valor para los que formulan la política monetaria. Por último, el ISI supera algunas de las limitaciones del INI, como son la falta de un criterio estadístico para definir el punto de corte de los bienes y servicios a excluir y el alto porcentaje del peso total del IPC eliminado. AbstractThis paper builds and evaluates several alternative measures of core inflation for Costa Rica. The chosen measure of core inflation is contrasted with the core inflation index (INI, which is the indicator of underlying inflation used today by the Central Bank of Costa Rica (BCCR. The main idea is that core inflation is a good indicator of the underlying inflation and catches the part of overall price change common to all the goods and services that is expected to persist in the

    Authigenic carbonates in a variety of types and shapes characterize mud diapirs and slump scarps, the major sites of fluid venting off Costa Rica margin. A regional distribution pattern of mineral and isotope compositions exists based on 76 samples analyzed so far: The Jaco Scarp, which represents a deep plow mark left by a subducted seamount, is characterized by nodules, fluid conduit concretions and chemoherms. The dominant mineral is (proto-)dolomite, except for chemoherms which are composed of aragonite. The dolomites have δ13C and δ18O compositions in the range of -40.5 to -28.3 ppm PDB and 8.1 to 6.5 ppm PDB, respectively, while those of chemoherm are lighter (δ13C = -46.0 to -51.0 ppm PDB and δ18O = 4.8 to 5.0 ppm PDB). On the mud diapirs off northern Costa Rica, the carbonates are mainly massive micrites which are dominated by calcite (MgCO_3 = 2--10 mol-%), their δ13C and δ18O are in the range of -27.4 to -53.0 ppm PDB and 5.4 to 6.3 ppm PDB, respectively. On the mud diapirs off southern Costa Rica, aragonite dominates the chemoherms (δ13C = -40.6 to -49.2 ppm PDB, δ18O = 4.4 to 6.4 ppm PDB) and high Mg-calcite dominates the seepage-associated crusts (δ13C = -51.9 to -52.7 ppm PDB; δ18O = 4.9 to 4.8 ppm PDB), while chimneys and fluid conduit concretions are composed of calcite with relatively low Mg content (δ13C = -32.4 to -41.5 ppm PDB; δ18O = 6.4 to 5.7 ppm PDB). The calcite precipitated inside chimneys is more depleted in 13C and has higher Mg-contents than the outer chimney walls, while the concretions are enriched in 13C and depleted in Mg-contents inside compared to outside layers. These trends indicate their sequences of growth. The gas hydrate-associated carbonates are unusually heavy isotopically (δ13C = -18.6 to -29.8 ppm PDB, δ18O = 6.0 to 6.8 ppm PDB) indicating a thermal origin of the methane-C as well as 18O enriched precipitating solutions. This agrees well with the C-isotope ratio of methane recovered from gas hydrates and Cl

    2011-01-01

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

  20. Olfactory communication among Costa Rican squirrel monkeys: a field study.

    1992-01-01

    Behaviors with a possible role in olfactory communication among troop members were investigated as part of a field study on the reproductive and foraging ecology of squirrel monkeys (Saimiri oerstedi) in Costa Rica. All age classes engaged in the olfaction-related behaviors. Apart from olfactory investigation of female genitals by males during the mating season, no other potential olfaction-related behavior (urine wash, branch investigation, rump, chest, back rub and sneeze) exceeded 1% of mean behavioral samples. Assessment of reproduction condition appears to be the primary function of such olfactory investigation of the female genital region. The primary function of urine washing is suggested to be the general communication of reproductive status, possibly facilitating reproductive synchrony. Sneezing, rump, back and chest rubbing do not appear to deposit substances active in olfactory communication. PMID:1306175

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

    Cifuentes, M.

    2012-12-01

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

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

  4. Agrochemical residues in rivers sediments, Poas, Costa Rica

    International Nuclear Information System (INIS)

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

    In 1993, the amphibian fauna of Las Tablas, Costa Rica, began to decline, and by 1998 approximately 50% of the species formerly present could no longer be found. Three years later, at the Reserva Forestal Fortuna, in western Panama, a site approximately 75 km east southeast of Las Tablas, KRL encountered a mass die-off of amphibians and a subsequent decline in abundance and species richness. The epidemiological features of the anuran population declines and die-offs at both sites were similar, suggesting a similar cause. Herein we document the presence of the fungus, Batrachochytrium dendrobatidis, in dead and dying wild frogs collected at Las Tablas just prior to population declines of several anuran species.

    Subtidal sediments of Isla del Coco (Cocos Island), Costa Rica were described in their grain size, sorting, organic matter, and carbonates from 27 dredge samples (3-75 m), collected in April 2010. The organic matter range between 1.37-3.31% and carbonates presented a mean of 74±17%. The sorting was moderately or poorly. The grain size ranged between 0.1-1.1mm. The pattern is that sediment change from inner to mouth of bays. Carbonates and gravel fractions increased offshore and organic matter have high values inner the bays. Input of vegetal debris and mud was from the rivers of this island covered with rain and cloud forest.

  7. Inflation persistence on Services and Regulated Goods in Costa Rica

    2014-11-01

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

Esta enfermedad es endémica en áreas tropicales de Asia y Australia y ha habido reportes aislados en Centro y Sur América. Aquí nosotros informamos del primer caso probado de melioidosis en Costa Rica, correspondiendo a un paciente sin historia de viajes a lugares endémicos. El paciente consultó por una bronconeumonía de adquisición comunitaria y sepsis. El hecho que el aislamiento bacteriano sea tan inusual en nuestro país implicó un retraso subsecuente en el inicio del tratamiento antibiótico específico en este caso, lo cual pudo influir en la evolución tan tórpida del paciente. Esto nos plantea el interrogante de si esta enfermedad debe ser incluida en el diagnóstico diferencial de sepsis de adquisición comunitaria en nuestro país.Melioidosis in an infectious disease caused by Burkholderia pseudomallei. This disease is endemie in areas of tropical Asia and Australia; there have been isolated reports of the disease in Central and South America. Here we report the first documented case of Melioidosis in Costa Rica in a patient without a history of traveling lo endemic areas. The patient was seen at the hospital because of sepsis and a community acquired bronchopneumonia. Due lo the rareness of this bacterial isolation in our country the corroboration of the diagnosis was delayed and subsequently the specific antibiotics were started 5 days later after the admission, this could have influenced the torpid evolution the patient had. This case should alert us and points lo the need of including this rare disease in the differential diagnosis of community acquired sepsis in our country.

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

    The NASA Engineering and Safety Center (NESC) received a request to develop an analysis model based on both frequency response and wave propagation analyses for predicting shock response spectrum (SRS) on composite materials subjected to pyroshock loading. The model would account for near-field environment (approx. 9 inches from the source) dominated by direct wave propagation, mid-field environment (approx. 2 feet from the source) characterized by wave propagation and structural resonances, and far-field environment dominated by lower frequency bending waves in the structure. This document contains appendices to the Volume I report.

    Full Text Available Según la Organización Mundial de la Salud, la infertilidad afecta a una de cada cuatro parejas en los países en desarrollo, en Costa Rica su incidencia se estima alrededor del 10% entre las parejas en edad fértil. En momentos en que la tasa de fecundidad en Costa Rica ha caído por debajo de su tasa de reemplazo, la infertilidad debe abordarse como un problema de salud pública prioritario. Por lo tanto, la Asamblea Legislativa de Costa Rica, en vez del inútil debate que ha sostenido por la aprobación de una técnica en particular como es la fecundación in vitro, debe enfocarse en aprobar una legislación sanitaria comprensiva que tome en cuenta el enfoque poblacional y establezca la creación de un Sistema Integrado de Atención de la Infertilidad. Este Sistema debe impulsar el abordaje interdisciplinario y la atención expedita y debe ofrecer terapias costo-efectivas que garanticen su sostenibilidad.Infertility affects one out of four couples in developing countries according to the World Health Organization, while its incidence in Costa Rica is estimated to be 10% in couples in reproductive - age. While the fertility rate in Costa Rica has fallen under the replacement rate, infertility must be approached as a public health priority. Therefore, instead of having the pointless discussion about approving a particular technique such as In vitro fertilization, the Costa Rican Legislative Assembly should focus on approving comprehensive health legislation. This legislation should be based on a population health approach and establish the creation of an Integrated System to Assist Fertility Problems. This System must thrust an interdisciplinary approach and prompt attention. It should also offer cost - effective therapies that guarantee its sustainability.

    2011-12-01

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

    The epithelial appendiceal neoplasms are uncommon and are usually detected as an unexpected surgical finding. The general surgeon should be aware of the diversity of its clinical manifestations and biological behaviors along with the significance of the surgical treatment on the progression of the illness and the prognosis of the patients. The operative findings and, especially, tumor histology, determine the type of surgery. Intestinal histologic subtype behaves and should be treated similarly to the right colon neoplasms; while mucinous tumors, often discordant between histology and its aggressiveness, can be treated with a simple appendectomy or require complex oncological surgeries. Mucinous tumors are often associated with the presence of mucin or tumor implants in the abdominal cavity, being the clinical syndrome known as pseudomyxoma peritonei (PMP). PMP tends to present an indolent but deadly evolution and requires a multimodal approach as a single treatment with curative potential: complete cytoreductive surgery plus hyperthermic Intra-peritoneal chemotherapy (CCRS + HIPEC) now considered the standard of care in this pathology. The general surgeon should be aware of the governing principles of the treatment of appendiceal neoplasms with or without peritoneal dissemination, know the therapeutic frontiers in every situation (avoiding unnecessary or counterproductive surgeries) and sending early these patients to specialised centres in the radical management of malignant diseases of the peritoneum in the conditions and with the necessary information to facilitate a possible radical treatment.

  5. Advanced Neutron Source enrichment study. Volume 2: Appendices -- Final report, Revision 12/94

    International Nuclear Information System (INIS)

    A study has been performed of the impact on performance of using low enriched uranium (20% 235U) or medium enriched uranium (35% 235U) as an alternative fuel for the Advanced Neutron Source, which is currently designed to use uranium enriched to 93% 235U. Higher fuel densities and larger volume cores were evaluated at the lower enrichments in terms of impact on neutron flux, safety, safeguards, technical feasibility, and cost. The feasibility of fabricating uranium silicide fuel at increasing material density was specifically addressed by a panel of international experts on research reactor fuels. The most viable alternative designs for the reactor at lower enrichments were identified and discussed. Several sensitivity analyses were performed to gain an understanding of the performance of the reactor at parametric values of power, fuel density, core volume, and enrichment that were interpolations between the boundary values imposed on the study or extrapolations from known technology. Volume 2 of this report contains 26 appendices containing results, meeting minutes, and fuel panel presentations. There are 26 appendices in this volume

  9. 35 years of electron microscopy in Costa Rica

    International Nuclear Information System (INIS)

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

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

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

  12. Antioxidant activity of Costa Rican propolis: a multivariate analysis approach

    International Nuclear Information System (INIS)

    Propolis is produced by Apis mellifera bees from resins of plants that are found around the apiary. The chemical composition is highly variable and Costa Rica has reported without studies of characterization to define the types of propolis in the country. 119 samples were collected from beekeeping areas of the country. The spectrum of 1H-NMR and its antioxidant activity against DPPH radical were measured. The spectra have been divided into 243 blocks of 0,04 ppm and processed with the Minitab software for multivariate analysis. 99 of the samples collected were used for construction of models for the valuation of the predictive ability of the model have been used coefficients of determination (R2) of prediction by the software and the remaining 20 samples. The existence of three types of propolis with chemically different metabolomes were determined by principal component analysis (PCA). A prediction model was constructed by analysis of partial least squares (PLS). The prediction model has allowed to classify a propolis according to the level of antioxidant activity (AAO), high (type I and II) or low (type III) from the spectrum of 1H-NMR. The R2 has been 0.88 and R2 prediction of 0, 718 for new samples. The nconiferyl benzoate of group I and nemorosone of the group II as two discriminated antioxidants among the groups I and II were isolated and high concentration levels of these compounds have been differentiated with respect to type III. This has allowed the construction of a linear discriminant model with a success rate of 100% for the samples used for formulation and 92,9 for the prediction of different samples. The classification systems could be applied to the standardization of the quality of propolis from Costa Rica for future medicinal or cosmetic applications that take advantage of its antioxidant properties. Also, the methylated derivative has isolated and identified of the nconiferyl benzoate thereof propolis than was obtained his counterpart

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

    1987-01-01

    This paper analyses movement patterns, habitat preferences, activity schedules, and dispersion of troop members in squirrel monkeys (Saimiri oerstedi) in relation to seasonal changes in food abundance in a Costa Rican tropical wet forest. Secondary forest was the preferred habitat and use of primary forest and late successional forest was limited primarily to seasons when food availability was low. Range area differed between seasons, varying from 79 to 110 ha, and totaling 176 ha over 11 months. The number of hectares used, hourly rate of group movement, and proportion of time spent foraging each season were all negatively related to relative food abundance. There was a tendency to spend less time in foraging activities in the middle of the day and to spend more time exclusively in travel at dawn and dusk. In all seasons dispersion was least when the troop was travelling and it was generally greatest during seasons of low food abundance. Measures of the allocation of time by the troop to food-related activities and the extent of troop dispersion each season were consistent with estimates based on behavior sampling of individuals.

  18. Trace metals in coastal sediments of Costa Rica

    International Nuclear Information System (INIS)

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

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

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

    In 1994, Oak Ridge National Laboratory (ORNL) was tasked by the National Park Service (NPS) to prepare an Environmental Report (ER) for Section 8B of the Foothills Parkway in the Great Smoky Mountains National Park (GSMNP). Section 8B represents 27.7 km (14.2 miles) of a total of 115 km (72 miles) of the planned Foothills Parkway and would connect the Cosby community on the east to the incorporated town of Pittman Center to the west. The major deliverables for the project are listed. From August 1995 through October 1996, NPS, GSMNP, and ORNL staff interacted with Federal Highway Administration staff to develop a conceptual design plan for Section 8B with the intent of protecting critical resources identified during the ER process to the extent possible. In addition, ORNL arranged for bioengineering experts to discuss techniques that might be employed on Section 8B with NPS, GSMNP, and ORNL staff during September 1996. For the purposes of this ER, there are two basic alternatives under consideration: (1) a build alternative and (2) a no-build alternative. Within the build alternative are a number of options including constructing Section 8B with no interchanges, constructing Section 8B with an interchange at SR 416 or U.S. 321, constructing Section 8B with a spur road on Webb Mountain, and considering operation of Section 8B both before and after the operation of Section 8C. The no-build alternative is considered the no-action alternative and is not to construct Section 8B. This volume of the ER consists of Appendices J through M, which describe potential impacts regarding traffic, noise, and aesthetics. The results of the traffic studies described in these appendices resulted in the following conclusions: Unacceptable levels of service will occur on numerous roads within and outside of the park increasingly in the Mure based upon current and future regional growth. However, the results of the traffic assessment indicated that there would be no significant or

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

  8. 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.

    An appendiceal mucocele (AM) is an uncommon differential in the patient being evaluated for acute appendicitis. Although often asymptomatic, AMs can clinically mimic acute appendicitis, and preoperative distinction between these processes facilitates optimal management. We report the case of a 60-year-old male with an AM presenting with nausea and periumbilical pain radiating to the right lower quadrant. Literature relevant to the diagnosis and treatment of AMs is reviewed, with emphasis on diagnosis through radiographic imaging and surgical management. Abdominal CT scan or ultrasound are useful in identifying AMs preoperatively. A decision to perform a right hemicolectomy should be influenced by the criteria reported by Gonzalez-Moreno. The safety of the laparoscopic resection relative to an open appendectomy is debated. PMID:27491099

    The performance of extravehicular activity (EVA) by National Aeronautics and Space Administration astronauts involves the risk of decompression sickness. This risk has been mitigated by the use of oxygen "prebreathe" to effectively wash out tissue nitrogen prior to each EVA. Now that the Space Shuttle Program (SSP) is being retired, high-pressure oxygen will become a limited resource. The In-Suit Light Exercise (ISLE) Prebreathe Protocol offers several potential benefits including its potential to save 6 pounds of oxygen per EVA. At the request of the NASA Engineering and Safety Center, the peer review convened on October 14, 2010. The major recommendation of the Review Committee was that the ISLE protocol was acceptable for operational use as a prebreathe option prior to EVA. The appendices to Volume I of the report are contained in this document.

    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. PMID:24252963

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

    Ackerman, Sara L

    2010-10-01

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

MÉTODOS: Estudo descritivo com dados do Sistema Único de Informações de Benefícios e dos Anuários Estatísticos da Previdência Social em 2007. A taxa de incidência de dor nas costas como causa das aposentadorias por invalidez foi calculada segundo as variáveis idade e sexo, nos estados. Os dias de trabalho perdidos por invalidez decorrente de dor nas costas foram calculados segundo atividade profissional. RESULTADOS: A dor nas costas idiopática foi a primeira causa de invalidez entre as aposentadorias previdenciárias e acidentárias. A maioria dos beneficiários residia em área urbana e era comerciário. A taxa de incidência de dor nas costas como causa das aposentadorias por invalidez no Brasil foi de 29,96 por 100.000 contribuintes. Esse valor foi mais elevado entre os homens e entre as pessoas mais velhas. Rondônia exibiu taxa quatro vezes superior ao esperado (RT = 4,05 e a segunda maior taxa, referente à Bahia, foi de aproximadamente duas vezes o esperado (RT = 2,07. Os comerciários foram responsáveis por 96,9% dos dias perdidos por invalidez. CONCLUSÕES: A dor nas costas foi uma importante causa de invalidez em 2007, sobretudo entre comerciários, com grandes diferenças entre os estados.

  14. Genetic admixture and population substructure in Guanacaste Costa Rica.

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

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

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

    Full Text Available La distrofia miotónica tipo1 (DM1 y el síndrome del cromosoma X frágil (FRAXA son dos enfermedades hereditarias relativamente comunes. Ambas constituyen ejemplos de un nuevo tipo de mecanismo mutacional, llamado mutaciones inestables o dinámicas, expansión de tripletas, o amplificación del ADN. La DM1 se considera como la distrofia muscular más frecuente en los adultos y FRAXA es la principal causa de retardo mental hereditario. Este trabajo presenta resultados actualizados de un estudio prospectivo no aleatorio en pacientes clínicamente afectados, que se realiza con el objetivo de confirmar el diagnóstico con técnicas moleculares (Hibridación de Southern y reacción en cadena de la polimerasa, PCR, y llevar a cabo el tamizaje en cascada del resto de la familia para ofrecerles consejo genético adecuado. Se confirmó el diagnóstico clínico inicial en la mayoría de los casos de distrofia miotónica, pero en los casos con retardo mental, más de la mitad de los análisis resultaron negativos para la amplificación en el gen FMR1, específica de FRAXA. La razón principal para esto podría ser el cuadro clínico muy sutil que muestran los niños afectados antes de la pubertad. Los únicos métodos disponibles para prevenir estas discapacidades por el momento son, el tamizaje en cascada, el consejo genético y el aborto selectivo. De los cuales, el último no se puede llevar a cabo según las leyes vigentes en Costa Rica.

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

    2013-12-01

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

    CYP2D6 differences have already been demonstrated within Latin American populations by the CEIBA.FP Consortium of the Ibero-American Network of Pharmacogenetics (RIBEF, as per the acronym in Spanish). However, within the population of Costa Rica, no research has been conducted until now, even though this population has a trihybrid component ancestry that represents an interesting condition. Thus, the present study was aimed to determine the frequency of Ultra-rapid Metabolizers (UMs) and Poor Metabolizers (PMs) in a Costa Rican population, as well as to determine whether there are differences in the CYP2D6-predicted phenotype frequencies among three Costa Rican groups with different ethnic backgrounds. Additionally, these frequencies of PMs and UMs obtained were compared with Ibero-American populations published data. Finally, we also aimed to describe allele frequencies among different Costa Rican ethnic groups. This research has been undertaken within the framework of the RIBEF CEIBA Consortium studies on Latin American populations. A total of 385 individuals were included in the study: 139 mestizos, 197 Amerindians, and 49 Afro-Caribbeans. CYP2D6 genotypes were determined by XL-PCR and Real-Time PCR. The CYP2D6 variant alleles *2, *3, *4, *5, *6, *10, "17, *29, *35 and *41 were also determined. For the entire Costa Rican population, the frequency of PMs and UMs was 6% and 6.5%, respectively. The percentage of UMs in the mestizo population was higher than in the Amerindian population. CYP2D6 UMs vary from 3.6% to 10.1% and PMs from 1.4% to 10.2% among three Costa Rican groups. The highest frequencies of UMs (10.1%) and PMs (10.2%) were found in the mestizo and Amerindian populations, respectively. In conclusion, the frequencies of UMs and PMs for CYP2D6 varied widely across the mestizo, Amerindian and Afro-Caribbean Costa Rican populations. Future research in this population should be oriented to identify new CYP2D6 variants through sequencing methods, as well as

The paper notes that the International Monetary Fund has insisted that Costa Rica’s monetary policy remain tight due to worries over inflation targets and a perceived risk of a balance of payments crisis. However, the author notes that the IMF could help prevent a balance of payments c...

  15. Geochemical Atlas of the San Jose and Golfito quadrangles, Costa Rica. Atlas Geoquimico de los cuadrangulos de San Jose y Golfito, Costa Rica

    Energy Technology Data Exchange (ETDEWEB)

    1987-07-01

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

    2014-12-01

    In this study we analysed rocks and noble gas composition of fluid inclusions (FIs) hosted in olivine crystals contained in a suite of eruptive products of the last 10ka of activity of Turrialba volcano, Cordillera Central, Costa Rica. The suite of analyzed rocks display a calc-alkaline affinity, ranging in composition from basaltic-andesite to dacite. Trace element patterns indicate a typical behavior of subduction-related magmas and also the clear contribution of an OIB-like signature at source. A group of andesites displays also adakite-like geochemical features, as evidenced by their constant depletion in HFSE elements. Sr isotope (0.703593 - 0.703678) and Nd isotope ratios (0.512960 - 0.512968) suggest that Turrialba magmas belong to one of the less contaminated mantle source of Central America. The 3He/4He ratio of fluid inclusions from the most mafic eruptive products (basaltic-andesites) varies from 7.86 to 8.07 Ra, while that from andesite lavas varies from 7.03 to 7.18 Ra. In order to understand the mantle source feeding Turrialba volcano, we performed a geochemical investigation on fumarolic gases of summit craters. The He isotope composition of dry gases of Turrialba volcano is characterized by extremely high R/Ra values (7.08-7.96 Ra). The highest 3He/4He ratios were measured at both West and Central Craters (7.93-7.96 Ra and 7.78-7.88 Ra, respectively), and are the highest values of the entire Central America. Despite the observed variability, the 3He/4He ratio of fumarolic gases and FIs from Turrialba volcano is well in the range of arc related volcanism (~7-8 Ra; Hilton et al., 2002), and represents the signature of a mantle wedge in which the contamination by crustal fluids is small to negligible. In addition the occurrence of recent adakite-like magmatism suggests the presence of an abnormal heating of the subducting lithosphere under Turrialba volcano, allowing even old or cold oceanic crust to melt.

    Full Text Available La Costa Maya est une région côtière du sud du Quintana Roo (Mexique, proche de l'îlet Ambergris au Bélize. Contrairement à la côte caribéenne du Mexique qui a souffert du développement du tourisme de masse à Cancun et le long de la Riviera Maya, la Costa Maya s'est orientée vers un développement durable avec notamment une faible densité de construction et le développement de l'écotourisme.Le développement s'est concentré autour de Puerto Costa Maya où un terminal de croisière a été construit en 2001. La station balnéaire (balneario de Majahual est devenue dépendante des 10-12 bateaux de touristes qui débarquaient chaque semaine. En dépit d'importants plans de développement, les plages reculées de la Costa Maya accueillaient tout au plus des écotouristes aisés et du tourisme lié à la plongée sous-marine.Le cyclone Dean, de catégorie 5, a dévasté le paysage en août 2007 et le rétablissement économique n'a pu être entamé que fin 2008, après la réouverture du terminal de croisière et la reconstruction de Majahual. Fin 2009, le trafic de croisière n'a pas retrouvé son niveau d'avant Dean et la récession mondiale couplée avec la grippe porcine et les violences liées à la drogue ont fait diminuer le tourisme en provenance des Etats-Unis. On ignore à quel niveau les nouvelles infrastructures tels l'aéroport international de Tulum qui propose un itinéraire de Chetumal à la plage et le nouveau complexe hôtelier à Xahuayxel, stimuleront la Costa Maya mexicaine créant peut-être une autoroute côtière reliée à San Pedro au Bélize.The Costa Maya is a vernacular coastal region of southeastern Quintana Roo (Mexico and adjacent Ambergris Cay, Belize.  As Mexico’s Caribbean coast suffered many growth pains associated with mass tourism development in Cancun and along the Riviera Maya, the Costa Maya by contrast was projected for more sustainable development including low-density housing and

  6. Safe Operation of Nuclear Power Plants. Code of Practice and Technical Appendices

    International Nuclear Information System (INIS)

    This book is in two parts. The first is a Code of Practice for the Safe Operation of Nuclear Power Plants and the second part is a compilation of technical appendices. Its object is to give information and illustrative examples that would be helpful in implementing the Code of Practice. This second part, although published under the same cover, is not part of the Code. Safe operation of a nuclear power plant postulates suitable siting and proper design, construction and management of the plant. Under the present Code of Practice for the Safe Operation of Nuclear Power Plants, those intending to operate the plant are recommended to prepare documentation which would deal with its operation and include safety analyses. The documentation in question would be reviewed by a regulatory body independent of the operating organization; operation would be authorized on the understanding that it would comply with limits and conditions designed to ensure safety. The Code may be subject to revision in the light of experience. The Appendices provide additional information together with some examples relating to certain topics dealt with in the Code; it must be emphasized that they are included as examples for information only and are not part of any recommendation. Purpose and scope: The recommendations in the Code are designed to protect the general public and the operating personnel from radiation hazards, and the Code forms part of the Agency's Safety Standards. The Code, which should be used in conjunction with the Agency's other Safety Standards, provides guidance and information to persons and authorities responsible for the operation of stationary nuclear power plants whose main function is the generation of thermal, mechanical or electrical power; it is not intended to apply to reactors used solely for experimental or research purposes. It sets forth minimum requirements which, it is believed, in the light of experience, must be met in order to achieve safe operation of a

    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. This result suggests that

    Full Text Available Los animales de laboratorio se usan como análogos a las enfermedades humanas, tanto en gnotobiología, investigación dental, embriología y teratología, oncología, gerontología, investigación cardiovascular, inmunolog��a, parasitología, virología, nutrición, genética y farmacología. Aunque en Costa Rica, la ciencia de animales de laboratorio es apenas incipiente, no existe información sobre los animales, la cantidad y para qué deberían de usarse. En Costa Rica rige desde el 13 de diciembre de 1994 la "Ley de Bienestar de los Animales", pero sin embargo esta Ley deja sin definir importantes aspectos técnicos y de control del uso de los animales de experimentación. Debería de existir un manual de referencia, aprobado por una Autoridad Nacional competente, sobre el manejo y uso de animales de laboratorio y, principalmente, cursos sobre ética y técnica del uso de este reactivo biológico dirigido a los investigadores. La legislación sobre el uso de animales de laboratorio en algunos países como los Estdos Unidos, Inglaterra, Canadá, Suecia, Colombia, Australia y Alemania son más estrictas. Sin embargo en Costa Rica desde 1992 se presentó un proyecto de Ley que pretendía regular los derechos de los animales proclamados en la Declaración Universal de los derechos del animal, pero en la actualidad se encuentra archivado. Sin embargo en 1993 fue publicado en la Gaceta No 242 del 20 de diciembre de 1993 el proyecto "Ley de Bienestar y Etiología de los Animales", que no tiene ningún antecedente directo en realción al uso de animales de laboratorio en Costa Rica pero desarrolla el marco jurídico de la Declaración Universal de los Derechos del Animal, proclamada por las Ligas Nacionales afiliadas a la ONU y aun no suscrita por Costa Rica.Laboratory animals are used like analogs to the human diseases, just as much in gnotobiology, dental investigation, embriology and teratology, oncology, gerontology, cardiovascular

    Full Text Available Justificación y objetivos: Los primeros casos de intoxicación por floraciones algales nocivas (FAN se reportaron en el país en 1990. Sin embargo desde finales de 1999 se ha observado un aumento drástico en el número de personas intoxicadas, especialmente en la costa pacífica del país. En Costa Rica existe gran desconocimiento acerca del problema. Debido al impacto que producen los fenómenos FAN en la salud pública, el turismo local y el ecosistema, es necesario describir las especies tóxicas y sus toxinas para tomar las medidas adecuadas de control y prevención. Métodos: Se realizaron muestreos de agua en varios sectores de la costa pacífica de nuestro país, con el objetivo de detectar las especies de microalgas potencialmente tóxicas y nocivas, y se interrogó a los pescadores locales. La identificación de las especies se realizó morfológicamente mediante microscopía de luz y electrónica de rastreo. Los hallazgos se compararon con la bibliografía y se propuso el potencial tóxico de estas microalgas, así como los métodos de análisis toxicológico, y la sintomatología de los afectados. Resultados: Observamos en Costa Rica un aumento en número de especies de microalgas productoras de FAN. Se reportaron las especies tóxicas productoras de FAN descritas por varios autores y las encontradas en este estudio. En algunas muestras de floraciones algales hemos encontrado bacterias grandes intracelulares, de forma bacilar, principalmente dentro del dinoflagelado Prorocentrum micans. Esta relación podría estar asociada a la toxigenicidad del alga. Hemos descrito la presencia de 26 dinoflagelados, 8 diatomeas y 1 cianobacteria tóxica en las FAN de las costas del Océano Pacífico costarricense. Conclusión: Se piensa que el aumento en la contaminación de las zonas costeras y el transporte de especies por medio de navíos pueden ser la causa de la aparición de estas microalgas.

    The Central Costa Rica Deformed Belt (CCRDB) is a ~100 km broad zone of deformation that marks the boundary between the Caribbean Plate and the Panama Microplate. From December 2011 to February 2012 an earthquake swarm took place on a portion of the CCRDB, near the town of Tobosi, in the Cartago province. In this study, we use data recorded by the National Seismological Network of Costa Rica (RSN: UCR-ICE) to relocate 22 of these earthquakes and calculate focal mechanisms. Additionally, we analyze the Tectonic Geomorphology of the region. Our results show a transtension structure near the town of Tobosi, which comprises at least three faults, named: the Tobosi, Tablon, and Alumbre faults. This structure is located only 5 km south of the Aguacaliente fault, which caused the deadliest earthquake in Costa Rican history on May 4, 1910 (Ms 6.4). The earthquake locations analyzed are aligned with the Tobosi Fault. The events varied in moment magnitude between 2.4 and 3.9 Mw and depths of 1 and 8 km. The largest events were felt mainly in the town of Tobosi and as far as San Jose, the capital city of Costa Rica. We found that the Tobosi fault is an active left-lateral strike-slip fault with a normal component and is the source of the Tobosi earthquake swarm. The study of active faults in Central Costa Rica is significant as it may greatly improve seismic hazards assessment for this region where most of the population and the main economic activities are concentrated.

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

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

    Full Text Available En este documento se estima una medida de la incertidumbre inflacionaria. Un modelo de inflación señala incertidumbre cuando los errores de pronóstico son heteroscedásticos. Por medio de la especificación de una ecuación GARCH (Generalized Autoregressive Conditional Heteroscedasticity, para la varianza del término de error de un modelo de inflación, es posible estimar una proxy de incertidumbre inflacionaria. La estimación simultánea del modelo de inflación y de la ecuación GARCH, produce un nuevo modelo de inflación en el cual los errores de pronóstico son homocedásticos. Existe consenso en la literatura económica en que hay una correlación positiva entre incertidumbre inflacionaria y la magnitud de la tasa de inflación, lo cual, como lo señaló Friedman (1977, representa uno de los costos asociados con la persistencia inflacionaria. Esto es porque tal incertidumbre dificulta la toma de decisiones óptimas por parte de los agentes económicos.La evidencia empírica, para el periodo 1954:01-2002:08, apoya la hipótesis de que para el caso de Costa Rica mientras mayor es la inflación mayor es la incertidumbre respecto a esta variable. En los últimos siete años (1997-2002 la incertidumbre presenta la variación media más baja de todo el periodo. Además, se identifica un efecto asimétrico de la inflación sobre la incertidumbre inflacionaria, es decir, la incertidumbre inflacionaria tiende a incrementarse más para el siguiente periodo cuando la inflación pronosticada está por debajo de la inflación actual, que cuando la inflación pronosticada está por arriba de la tasa observada de inflación. Estos resultados tienen una clara implicación para la política monetaria. Para minimizar la dificultad que la inflación causa en la toma óptima de decisiones de los agentes económicos es necesario perseguir no solamente un nivel bajo de inflación sino que también sea estable.AbstractThis paper estimates a measure of

    The Cold Water Pipe System Design Study was undertaken to evaluate the diverse CWP concepts, recommend the most viable alternatives for a 1984 deployment of the 10 to 40 MWe MEP, and carry out preliminary designs of three concepts. The concept evaluation phase reported involved a systems analysis of design alternatives in the broad categories of rigid walled (with hinges), compliant walled, stockade and bottom mounted buoyant. Quantitative evaluations were made of concept performance, availability, deployment schedule, technical feasibility and cost. CWP concepts were analyzed to determine if they met or could be made to meet established system requirements and could be deployed by 1984. Fabrication, construction and installation plans were developed for successful concepts, and costs were determined in a WBS format. Evaluations were performed on the basis of technical and cost risk. This volume includes the following appendices: (A) materials and associated design criteria; (B) summary of results of dynamic flow and transportation analysis; (C) CWP sizing analysis; (D) CWP thermal performance; and (E) investigation of the APL/ABAM CWP design.

    Dravo Lime has for many years supplied magnesium containing lime in the ranges of 3-6% MgO. Several years ago Dravo Lime realized the potential operating savings its FGD customers could benefit from if magnesium could be recovered from FGD waste streams. As a result, several different proprietary processes have been developed for the recovery of magnesium hydroxide. These recovery processes include steps for magnesium hydroxide separation, purification, and crystal growth. The process implemented at The Cincinnati Gas Electric Company`s Wm. H. Zimmer Station was piloted by Dravo Lime Company at Allegheny Power System`s Mitchell Station near Monongahela, PA during the fourth quarter in 1989 and first quarter in 1990. This pilot work was the foundation for further development of the ThioClear process at Dravo`s pilot plant at CG&E Miami Fort Station. The ThioClear process is a closed loop version of the magnesium hydroxide recovery process with the same unit operations and products but also including an absorber tower for scrubbing flue gas. Testing at Miami Fort of the ThioClear process led to improvements in separation of magnesium hydroxide from gypsum that are part of the magnesium hydroxide recovery process installed at Zimmer Station.

    The objective of this project is the development of a preliminary design for a full-sized, closed cycle, ammonia power system module for the 100 MWe OTEC demonstration plant. In turn, this demonstration plant is to demonstrate, by 1984, the operation and performance of an Ocean Thermal Power Plant having sufficiently advanced heat exchanger design to project economic viability for commercial utilization in the late 1980's and beyond. Included in this power system development are the preliminary designs for a proof-of-concept pilot plant and test article heat exchangers which are scaled in such a manner as to support a logically sequential, relatively low-cost development of the full-scale power system module. The conceptual designs are presented for the demonstration plant power module, the proof-of-concept pilot plant, and for a pair of test article heat exchangers. Costs associated with the design, development, fabrication, checkout, delivery, installation, and operation are included. The accompanying design and producibilty studies on the full-scale power system module project the performance/economics for the commercial plant. This section of the report contains appendices on the electrical system, instrumentation and control, ammonia pump evaluation study, ammonia and nitrogen support subsystems, piping and support design calculations, and plant availability.

    The development of two new probabilistic accident consequence codes, MACCS and COSYMA, was completed in 1990. These codes estimate the consequence from the accidental releases of radiological material from hypothesized accidents at nuclear installations. In 1991, the US Nuclear Regulatory Commission and the Commission of the European Communities began cosponsoring a joint uncertainty analysis of the two codes. The ultimate objective of this joint effort was to systematically develop credible and traceable uncertainty distributions for the respective code input variables. A formal expert judgment elicitation and evaluation process was identified as the best technology available for developing a library of uncertainty distributions for these consequence parameters. This report focuses on the results of the study to develop distribution for variables related to the MACCS and COSYMA late health effects models.

    The objective of this project is the development of a preliminary design for a full-sized, closed cycle, ammonia power system module for the 100 MWe OTEC demonstration plant. In turn, this demonstration plant is to demonstrate, by 1984, the operation and performance of an Ocean Thermal Power Plant having sufficiently advanced heat exchanger design to project economic viability for commercial utilization in the late 1980's and beyond. Included in this power system development are the preliminary designs for a proof-of-concept pilot plant and test article heat exchangers which are scaled in such a manner as to support a logically sequential, relatively low-cost development of the full-scale power system module. The conceptual designs are presented for the demonstration plant power module, the proof-of-concept pilot plant, and for a pair of test article heat exchangers. Costs associated with the design, development, fabrication, checkout, delivery, installation, and operation are included. The accompanying design and producibilty studies on the full-scale power system module project the performance/economics for the commercial plant. This section of the report contains appendices on the developed computer models, water system dynamic studies, miscellaneous performance analysis, materials and processes, detailed equipment lists, turbine design studies, tube cleaner design, ammonia leak detection, and heat exchanger design supporting data.

    The development of two new probabilistic accident consequence codes, MACCS and COSYMA, was completed in 1990. These codes estimate the consequence from the accidental releases of radiological material from hypothesized accidents at nuclear installations. In 1991, the US Nuclear Regulatory Commission and the Commission of the European Communities began cosponsoring a joint uncertainty analysis of the two codes. The ultimate objective of this joint effort was to systematically develop credible and traceable uncertainty distributions for the respective code input variables. A formal expert judgment elicitation and evaluation process was identified as the best technology available for developing a library of uncertainty distributions for these consequence parameters. This report focuses on the results of the study to develop distribution for variables related to the MACCS and COSYMA deposited material and external dose models. This volume contains appendices that include (1) a summary of the MACCS and COSYMA consequence codes, (2) the elicitation questionnaires and case structures, (3) the rationales and results for the panel on deposited material and external doses, (4) short biographies of the experts, and (5) the aggregated results of their responses.

    1985-04-01

    This final report is submitted as part of the Green River Ambient Model Assessment (GRAMA) project conducted at the US Department of Energy's Pacific Northwest Laboratory for the US Environmental Protection Agency. The GRAMA Program has, as its ultimate goal, the development of validated air quality models that can be applied to the complex terrain of the Green River Formation of western Colorado, eastern Utah and southern Wyoming. The Green River Formation is a geologic formation containing large reserves of oil shale, coal, and other natural resources. Development of these resources may lead to a degradation of the air quality of the region. Air quality models are needed immediately for planning and regulatory purposes to assess the magnitude of these regional impacts. This report documents one of the models being developed for this purpose within GRAMA - specifically a model to predict short averaging time (less than or equal to 24 h) pollutant concentrations resulting from the mesoscale transport of pollutant releases from multiple sources. MELSAR has not undergone any rigorous operational testing, sensitivity analyses, or validation studies. Testing and evaluation of the model are needed to gain a measure of confidence in the model's performance. This report consists of two volumes. This volume contains the Appendices, which include listings of the FORTRAN code and Volume 1 contains the model overview, technical description, and user's guide. 13 figs., 10 tabs.

  20. Analysis of core damage frequency: Peach Bottom, Unit 2 internal events appendices

    International Nuclear Information System (INIS)

    This document contains the appendices for the accident sequence analysis of internally initiated events for the Peach Bottom, Unit 2 Nuclear Power Plant. This is one of the five plant analyses conducted as part of the NUREG-1150 effort for the Nuclear Regulatory Commission. The work performed and described here is an extensive reanalysis of that published in October 1986 as NUREG/CR-4550, Volume 4. It addresses comments from numerous reviewers and significant changes to the plant systems and procedures made since the first report. The uncertainty analysis and presentation of results are also much improved, and considerable effort was expended on an improved analysis of loss of offsite power. The content and detail of this report is directed toward PRA practitioners who need to know how the work was done and the details for use in further studies. The mean core damage frequency is 4.5E-6 with 5% and 95% uncertainty bounds of 3.5E-7 and 1.3E-5, respectively. Station blackout type accidents (loss of all ac power) contributed about 46% of the core damage frequency with Anticipated Transient Without Scram (ATWS) accidents contributing another 42%. The numerical results are driven by loss of offsite power, transients with the power conversion system initially available operator errors, and mechanical failure to scram. 13 refs., 345 figs., 171 tabs

    1980-10-01

    This EIS analyzes the significant environmental impacts that could occur if various technologies for management and disposal of high-level and transuranic wastes from commercial nuclear power reactors were to be developed and implemented. This EIS will serve as the environmental input for the decision on which technology, or technologies, will be emphasized in further research and development activities in the commercial waste management program. The action proposed in this EIS is to (1) adopt a national strategy to develop mined geologic repositories for disposal of commercially generated high-level and transuranic radioactive waste (while continuing to examine subseabed and very deep hole disposal as potential backup technologies) and (2) conduct a R and D program to develop such facilities and the necessary technology to ensure the safe long-term containment and isolation of these wastes. The Department has considered in this statement: development of conventionally mined deep geologic repositories for disposal of spent fuel from nuclear power reactors and/or radioactive fuel reprocessing wastes; balanced development of several alternative disposal methods; and no waste disposal action. This volume contains appendices of supplementary data on waste management systems, geologic disposal, radiological standards, radiation dose calculation models, related health effects, baseline ecology, socio-economic conditions, hazard indices, comparison of defense and commercial wastes, design considerations, and wastes from thorium-based fuel cycle alternatives.

    The overall, long term objective of the Solar Central Receiver Hybrid Power System is to identify, characterize, and ultimately demonstrate the viability and cost effectiveness of solar/fossil, steam Rankine cycle, hybrid power systems that: (1) consist of a combined solar central receiver energy source and a nonsolar energy source at a single, common site, (2) may operate in the base, intermediate, and peaking capacity modes, (3) produce the rated output independent of variations in solar insolation, (4) provide a significant savings (50% or more) in fuel consumpton, and (5) produce power at the minimum possible cost in mills/kWh. It is essential that these hybrid concepts be technically feasible and economically competitive with other systems in the near to mid-term time period (1985-1990) on a commercial scale. The program objective for Phase I is to identify and conceptually characterize solar/fossil steam Rankine cycle, commercial-scale, power plant systems that are economically viable and technically feasible.

  5. Use of transportable storage casks in the nuclear waste management system: Appendices

    International Nuclear Information System (INIS)

    A study was performed to determine the viability of the use of transportable storage casks (TSCs), and other metal casks that are designed primarily for storage but which might be used to ship their stored contents to DOE on a one-time use basis (referred to in this study as storage only casks, or SOCs), in the combined utility/DOE spent fuel management system. The viability of the use of TSCs and SOCs was assessed in terms of the costs and savings involved in their use, the sensitivity of these costs and savings to changes in the capacity and cost of fabrication of the casks, the impacts of variation in cask design features on cost and radiation exposure of personnel, and their prospective use in connection with the transport of defense high level wastes. Estimates were developed of the costs of acquiring and handling of TSCs and SOCs at reactor sites. For comparison purposes, similar costs were developed for the use of concrete storage casks at reactor sites. Estimates of the savings involved to the DOE system as a result of receiving spent fuel in TSCs or SOCs were separately developed. These costs are developed and presented in Volume 2, Appendices A through J

  2. 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.

  3. Exploring the Notion That Subduction Erosion Has Removed or Submerged Costa Rica's Early Tertiary Arc Massifs

    Scholl, D. W.

    2007-05-01

    Arc igneous rocks of Paleocene, Eocene, and Oligocene age are widely exposed in the southern, coastal region of Panama (Lissinna et al., EGU abstract, 2006). These rocks intrude or overlie mafic basement rock of the Caribbean Large Igneous Province (CLIP) of Late Cretaceous age that extends to the east to underlie the Caribbean Basin and form the Caribbean plate. Immediately west of Panama, in coastal Costa Rica, exposures of CLIP basement are not intruded or overlain by arc magmatic rocks of early Tertiary age. EXPLANATIONS: Potentially, the early Tertiary subduction zone that dipped beneath the Pacific margin of Panama did not extend to the west, thus no arc magmatism occurred where Costa Rica presently exists. Alternatively, the subduction zone bordering the Pacific edge of the CLIP extended below Costa Rica but former exposures of early Tertiary arc magmatic rocks piled there have been erosionally removed or buried beneath Miocene and younger arc massifs of interior mountain belts. EXPLORING A SUBDUCTION EROSION EXPLANATION Onshore and offshore evidence documents that subduction erosion thins and truncates the submerged rock framework of the Middle and South America forearc. The eroded (removed) material is transported toward and into the mantle within the subduction channel separating the upper plate of the forearc and lower plate of the subducting oceanic crust. The long-term (greater than 10 Myr) rate of truncation (i. e., migration of the trench toward a fixed, onshore reference) averages 2 to 3 km/Myr. Because of the subduction of the aseismic Cocos Ridge beneath Costa Rica, during at least the past 4 to 5 Myr the rate of truncation at this margin has been much higher. It is proposed that during the past 50 Myr subduction erosion has truncated the Costa Rica forearc by at least 100 km and either obliterated or deeply submerged arc massifs of early Tertiary age. Their exposed presence to the east in neighboring Panama reflects the circumstance that since

    Full Text Available RESUMENEn este trabajo se logró conocer los criterios de clasificación empleados para definir a la población con discapacidad en los registros censales del siglo XX en Costa Rica y, por consiguiente, una aproximación a las formulaciones conceptuales para referirse al grupo en estudio. Además, se caracterizó a ese segmento poblacional a partir de diferentes variables: sexo, edad, estado civil y distribución geográfica. También se abordaron otros aspectos como fueron: alfabetismo, nivel de educación, ocupación, jefatura de hogar y vivienda. Entre los hallazgos más destacables se encuentra la permanencia, en los registros censales del siglo XX, de un concepto de discapacidad basado en la deficiencia, lo que definió los criterios de clasificación para esa población en esas fuentes. Asimismo se constató, por una parte, la asociación entre discapacidad e inequidad en esa centuria y, por la otra, la fragilidad de los vínculos de parentesco en ese grupo poblacional con respecto al conjunto de hogares de Costa Rica a fines de ese siglo. Las fuentes empleadas en esta investigación fueron los censos de población de Costa Rica del siglo XX. En el procedimiento con los datos, se llevó a cabo un análisis descriptivo de distribución de frecuencias. ABSTRACTThis research discloses the classification criteria used to define the population with disability in the twentieth century census records in Costa Rica and therefore gives an approximation of the conceptual formulations needed to refer to the examined group. Additionally, a segment of the population has been characterized by sex, age, marital status and geographical distribution. Other aspects like literacy rate, education level, occupation, head of household and housing were also dealt with. The disability concept based on deficiency, which defined the classification criteria for the population in those data sources, is among the most significant findings of this research. Furthermore

    2003-10-01

    Full Text Available Justificación y objetivos: Los primeros casos de intoxicación por floraciones algales nocivas (FAN se reportaron en el país en 1990. Sin embargo desde finales de 1999 se ha observado un aumento drástico en el número de personas intoxicadas, especialmente en la costa pacífica del país. En Costa Rica existe gran desconocimiento acerca del problema. Debido al impacto que producen los fenómenos FAN en la salud pública, el turismo local y el ecosistema, es necesario describir las especies tóxicas y sus toxinas para tomar las medidas adecuadas de control y prevención. Métodos: Se realizaron muestreos de agua en varios sectores de la costa pacífica de nuestro país, con el objetivo de detectar las especies de microalgas potencialmente tóxicas y nocivas, y se interrogó a los pescadores locales. La identificación de las especies se realizó morfológicamente mediante microscopía de luz y electrónica de rastreo. Los hallazgos se compararon con la bibliografía y se propuso el potencial tóxico de estas microalgas, así como los métodos de análisis toxicológico, y la sintomatología de los afectados. Resultados: Observamos en Costa Rica un aumento en número de especies de microalgas productoras de FAN. Se reportaron las especies tóxicas productoras de FAN descritas por varios autores y las encontradas en este estudio. En algunas muestras de floraciones algales hemos encontrado bacterias grandes intracelulares, de forma bacilar, principalmente dentro del dinoflagelado Prorocentrum micans. Esta relación podría estar asociada a la toxigenicidad del alga. Hemos descrito la presencia de 26 dinoflagelados, 8 diatomeas y 1 cianobacteria tóxica en las FAN de las costas del Océano Pacífico costarricense. Conclusión: Se piensa que el aumento en la contaminación de las zonas costeras y el transporte de especies por medio de navíos pueden ser la causa de la aparición de estas microalgas. Estas son capaces de producir: intoxicaci

    The development of two new probabilistic accident consequence codes, MACCS and COSYMA, completed in 1990, estimate the risks presented by nuclear installations based on postulated frequencies and magnitudes of potential accidents. In 1991, the US Nuclear Regulatory Commission (NRC) and the Commission of the European Communities (CEC) began a joint uncertainty analysis of the two codes. The objective was to develop credible and traceable uncertainty distributions for the input variables of the codes. Expert elicitation, developed independently, was identified as the best technology available for developing a library of uncertainty distributions for the selected consequence parameters. The study was formulated jointly and was limited to the current code models and to physical quantities that could be measured in experiments. To validate the distributions generated for the wet deposition input variables, samples were taken from these distributions and propagated through the wet deposition code model along with the Gaussian plume model (GPM) implemented in the MACCS and COSYMA codes. Resulting distributions closely replicated the aggregated elicited wet deposition distributions. Project teams from the NRC and CEC cooperated successfully to develop and implement a unified process for the elaboration of uncertainty distributions on consequence code input parameters. Formal expert judgment elicitation proved valuable for synthesizing the best available information. Distributions on measurable atmospheric dispersion and deposition parameters were successfully elicited from experts involved in the many phenomenological areas of consequence analysis. This volume is the second of a three-volume document describing the project and contains two appendices describing the rationales for the dispersion and deposition data along with short biographies of the 16 experts who participated in the project.

  12. Early Site Permit Demonstration Program: Guidelines for determining design basis ground motions. Volume 2, Appendices

    Energy Technology Data Exchange (ETDEWEB)

    1993-03-18

    This report develops and applies a methodology for estimating strong earthquake ground motion. The motivation was to develop a much needed tool for use in developing the seismic requirements for structural designs. An earthquake`s ground motion is a function of the earthquake`s magnitude, and the physical properties of the earth through which the seismic waves travel from the earthquake fault to the site of interest. The emphasis of this study is on ground motion estimation in Eastern North America (east of the Rocky Mountains), with particular emphasis on the Eastern United States and southeastern Canada. Eastern North America is a stable continental region, having sparse earthquake activity with rare occurrences of large earthquakes. While large earthquakes are of interest for assessing seismic hazard, little data exists from the region to empirically quantify their effects. The focus of the report is on the attributes of ground motion in Eastern North America that are of interest for the design of facilities such as nuclear power plants. This document, Volume II, contains Appendices 2, 3, 5, 6, and 7 covering the following topics: Eastern North American Empirical Ground Motion Data; Examination of Variance of Seismographic Network Data; Soil Amplification and Vertical-to-Horizontal Ratios from Analysis of Strong Motion Data From Active Tectonic Regions; Revision and Calibration of Ou and Herrmann Method; Generalized Ray Procedure for Modeling Ground Motion Attenuation; Crustal Models for Velocity Regionalization; Depth Distribution Models; Development of Generic Site Effects Model; Validation and Comparison of One-Dimensional Site Response Methodologies; Plots of Amplification Factors; Assessment of Coupling Between Vertical & Horizontal Motions in Nonlinear Site Response Analysis; and Modeling of Dynamic Soil Properties.

  13. In situ radionuclide migration studies in a shallow sand aquifer. Part. 1. Part. 2: appendices

    International Nuclear Information System (INIS)

    As a result of a study of the geology of the British Nuclear Fuels premises at Drigg, Cumbria, the British Geological Survey identified a shallow glacial sand deposit approximately 1.5m thick, interbedded between two clay horizons. An array of boreholes has been constructed in this sand in order to study the migration of radionuclides introduced into the formation under controlled conditions of groundwater flow. Conservative tracers used in the field test include chloride (as NaCl) and iodine-131 (as NaI). Strontium-85 (as the chloride) has been used as a chemically reactive tracer in conjunction with 131I. The principal research objectives of the programme are as follows: (1) To undertake laboratory batch sorption experiments using core material from the field site in order to choose those nuclides of radiological interest that would migrate sufficiently quickly for their behaviour to be studied in a field experiment within a reasonable time period. (2) To identify and quantify the mechanisms for nuclide/sediment interaction by determination of the geochemical distribution of 85Sr in contaminated cores using a sequential leaching procedure. (3) To obtain appropriate data on the hydraulic characteristics of the sand formation in order to construct a mathematical model to describe groundwater flow and reactive mass transport. Part 2 of this report contains the following appendices: (1) Calculation of sorption parameters. (2) A low-cost manifold system for use with multi-level samplers. (3) Radioactivity curves for 131I and 85Sr. (4) Results of particle size analysis for sand aquifers

    In 1994, Oak Ridge National Laboratory (ORNL) was tasked by the National Park Service (NPS) to prepare an Environmental Report (ER) for Section 8B of the Foothills Parkway in the Great Smoky Mountains National Park (GSMNP). Section 8B represents 27.7 km (14.2 miles) of a total of 115 km (72 miles) of the planned Foothills Parkway and would connect the Cosby community on the east to the incorporated town of Pittman Center to the west. The major deliverables for the project are listed. From August 1995 through October 1996, NW, GSMNP, and ORNL staff interacted with Federal Highway Administration staff to develop a conceptual design plan for Section 8B with the intent of protecting critical resources identified during the ER process to the extent possible. In addition, ORNL arranged for bioengineering experts to discuss techniques that might be employed on Section 8B with NPS, GSMNP, and ORNL staff during September 1996. For the purposes of this EN there are two basic alternatives under consideration: (1) a build alternative and (2) a no-build alternative. Within the build alternative are a number of options including constructing Section 8B with no interchanges, constricting Section 8B with an interchange at SR 416 or U.S. 321, constructing Section 8B with a spur road on Webb Mountain, and considering operation of Section 8B both before and after the operation of Section 8C. The no-build alternative is considered the no-action alternative and is not to construct Section 8B. This volume of the ER, which consists of Appendices A, B, and C, assesses the potential geologic impacts of the proposed Section 8B construction, presents the results of the Section 8B soil survey, and describes the water quality studies and analyses performed for the ER. The following summary sections provide information for geology, soils, and water quality.

  15. Probabilistic accident consequence uncertainty analysis: Food chain uncertainty assessment. Volume 2: Appendices

    International Nuclear Information System (INIS)

    This volume is the second of a two-volume document that summarizes a joint project by the US Nuclear Regulatory and the Commission of European Communities to assess uncertainties in the MACCS and COSYMA probabilistic accident consequence codes. These codes were developed primarily for estimating the risks presented by nuclear reactors based on postulated frequencies and magnitudes of potential accidents. This two-volume report, which examines mechanisms and uncertainties of transfer through the food chain, is the first in a series of five such reports. A panel of sixteen experts was formed to compile credible and traceable uncertainty distributions for food chain transfer that affect calculations of offsite radiological consequences. Seven of the experts reported on transfer into the food chain through soil and plants, nine reported on transfer via food products from animals, and two reported on both. The expert judgment elicitation procedure and its outcomes are described in these volumes. This volume contains seven appendices. Appendix A presents a brief discussion of the MAACS and COSYMA model codes. Appendix B is the structure document and elicitation questionnaire for the expert panel on soils and plants. Appendix C presents the rationales and responses of each of the members of the soils and plants expert panel. Appendix D is the structure document and elicitation questionnaire for the expert panel on animal transfer. The rationales and responses of each of the experts on animal transfer are given in Appendix E. Brief biographies of the food chain expert panel members are provided in Appendix F. Aggregated results of expert responses are presented in graph format in Appendix G

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

  18. Arsenic determination in water supplies for human consumption of the province of Cartago, Costa Rica

    International Nuclear Information System (INIS)

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

  19. Electric load management in developing countries: Costa Rica leads the way

    International Nuclear Information System (INIS)

    Energy planners in developing countries have traditionally sought to meet their nations' growing electricity demands by adding more generation and transmission capacity. But as the foreign investment situation became critical in the 1980s, private investment and system efficiency improvement programmes began to garner interest. One of the most promising system efficiency improvement options is load management, which uses a variety of techniques to utilize the electricity system's existing capacity more efficiently. However, to date, only three countries have seriously considered implementing large load management programmes: Pakistan, Peru and Costa Rica. This paper describes a 1987-89 load control demonstration programme in Costa Rica, sponsored by the US Agency for International Development (AID), in which participating industries were able to reduce their peak demand by 14%.

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

    Diversity and microstructure of quitons (Mollusca: Polyplacophora) from the Caribbean of Costa Rica. The polyplacophorans of the coral reef on the Caribbean coast of Costa Rica have been insufficiently studied. The examination of coral rubble accumulated in the shallow sublitoral waters on four collection stations in Provincia Limón revealed a higher diversity of chitons than was documented. From the country eight species were previously known: Ischnochiton erythronotus (C.B. Adams 1845); Ischnoplax pectinata (Sowerby 1840); Stenoplax boogii (Haddon 1886); S. purpurascens (C.B. Adams 1845); Acanthopleura granulata (Gmelin 1791); Chiton marmoratus Gmelin 1791; C. tuberculatus Linnaeus 1758 and Acanthochitona rhodea (Pilsbry 1893). This study added five more species that are reported here for the first time: Callistochiton portobelensis Ferreira 1976; Ischnochiton kaasi Ferreira 1987; I. pseudovirgatus Kaas 1972; Acanthochitona balesae Abbott 1954 and Cryptoconchus floridanus (Dall 1889).

  3. A cross-taxa survey of organochlorine pesticide contamination in a Costa Rican wildland

    International Nuclear Information System (INIS)

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

    Parallel to a zooplankton study (1999-2000) observations were made (from an inflatable boat), on the presence of dolphins along a transect (-8 km long) on the axis of Culebra Bay (24 km2), Gulf of Papagayo, Pacific coast of Costa Rica. Dolphins were found during 20 of the 31 boat surveys conducted. The only species of cetacean found in the bay was Stenella attenuata, the spotted dolphin. These sightings were more frequent during the rainy season, particularly during the month of May of both years. The presence of S. attenuata in Culebra Bay might be associated to the abundances of fish and mollusks (their presumed prey: for example, squids), as evidenced by fishery statistics available for this zone of the Pacific coast of Costa Rica.

    Full Text Available The article presents an analysis of the economic policy of energy in Costa Rica and of the exceptional role which the Costa Rican Institute of Electricity (ICE – the company responsible for the provision of energy and telecommunications – has historically held in shaping the national identity. The basic assumption is that the institutional profile of the ICE, as well as its evolution and impact on development have been shaped by very specific political, social and economic conditions which are difficult to replicate in other developing countries in the South. It is specifically argued that, since its foundation in 1949, ICE has become one of the cornerstones of a peculiar kind of welfare state and of a solidarity model for development which is listed among the most advanced in the world in terms of social progress.

    Linkage disequilibrium (LD) analysis provides a powerful means for screening the genome to map the location of disease genes, such as those for bipolar disorder (BP). As described in this paper, the population of the Central Valley of Costa Rica, which is descended from a small number of founders, should be suitable for LD mapping; this assertion is supported by reconstruction of extended haplotypes shared by distantly related individuals in this population suffering low-frequency hearing loss (LFHL1), which has previously been mapped by linkage analysis. A sampling strategy is described for applying LD methods to map genes for BP, and clinical and demographic characteristics of an initially collected sample are discussed. This sample will provide a complement to a previously collected set of Costa Rican BP families which is under investigation using standard linkage analysis. 42 refs., 4 figs., 2 tabs.

    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

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

    The eco-epidemiology of American cutaneous leishmaniasis (ACL) is driven by animal reservoir species that are a source of infection for sand flies that serve as vectors infecting humans with Leishmania spp parasites. The emergence and re-emergence of this disease across Latin America calls for further studies to identify reservoir species associated with enzootic transmission. Here, we present results from a survey of 52 individuals from 13 wild mammal species at endemic sites in Costa Rica a...

    Salt is a major determinant of population blood pressure levels. Salt intake in Costa Rica is above levels required for good health. With an increasing number of Costa Ricans visiting fast food restaurants, it is likely that fast-food is contributing to daily salt intake. Salt content data from seven popular fast food chains in Costa Rica were collected in January 2013. Products were classified into 10 categories. Mean salt content was compared between chains and categories. Statistical analysis was performed using Welch ANOVA and Tukey-Kramer HSD tests. Significant differences were found between companies; Subway products had lowest mean salt content (0.97 g/100 g; p KFC had the highest (1.57 g/100 g; p < 0.05). Significant variations in mean salt content were observed between categories. Salads had a mean salt content of 0.45 g/100 g while sauces had 2.16 g/100 g (p < 0.05). Wide variation in salt content was also seen within food categories. Salt content in sandwiches ranged from 0.5 to 2.1 g/100 g. The high levels and wide variation in salt content of fast food products in Costa Rica suggest that salt reduction is likely to be technically feasible in many cases. With an increasing number of consumers purchasing fast foods, even small improvements in salt levels could produce important health gains. PMID:25171851

  18. Understanding key drivers controlling daily stable isotope variations in precipitation of Costa Rica, Central America

    Costa Rica is located on the Central American Isthmus, which receives direct moisture inputs from the Caribbean Sea and the Pacific Ocean. The relatively narrow, but high relief Central American land bridge is characterized by unique mountainous and lowland microclimates. However, only limited knowledge exists about the impact of relief and regional atmospheric circulation patterns on precipitation origin, transport, and isotopic composition in this tropical region. Therefore, the main scope of this study is to identify the key drivers controlling variations in meteoric waters of Costa Rica using stable isotopes based on daily sample collection for the year 2013. The monitoring sites comprise three strategic locations across Costa Rica: Heredia (Central Valley), Turrialba (Caribbean slope), and Caño Seco (South Pacific slope). Sporadic dry season rain is mostly related to isolated enriched events ranging from -5.8‰ d18O up to -0.9‰ d18O. By mid-May, the Intertropical Convergence Zone reaches Costa Rica resulting in a notable depletion in isotope ratios (up to -18.5‰ d18O). HYSPLIT back air mass trajectories indicate the strong influence on the origin and transport of precipitation of two main moisture transport mechanisms, the Caribbean Low Level Jet and the Colombian Low Level Jet as well as localized convection events. Multiple linear regression models constructed based on Random Forests of surface meteorological information and atmospheric sounding profiles suggest that Lifted Condensation Level and surface relative humidity are the main factors controlling isotopic variations. These findings diverge from the recognized 'amount effect' in monthly composite samples across the tropics. Understanding of stable isotope dynamics in tropical precipitation can be used to enhance catchment and groundwater modeling efforts in ungauged basins where scarcity of long-term monitoring data drastically limit current and future water resources management.

    Compensation to landowners for forest-derived environmental services has gained international recognition as a mechanism to combat forest loss and fragmentation. This approach is widely promoted, although there is little evidence demonstrating that environmental service payments encourage forest stewardship and conservation. Costa Rica provides a unique case study in which a 1996 Forestry Law initiated environmental service payments and prohibited forest conversion to other land uses. We exam...
