Glaucoma is the third-most-frequent cause of blindness in the world, with a total of 5.2 million blind people as a result of this disease; 80% live in developing countries. In Paraguay, after cataract it is the second-most-frequent-cause. Early detection of the risk factors and groups can help to avoid progress of this disease. Trauma, cataract and infectious uveitis represent special risks for developing secondary glaucoma, which is a more frequent cause of blindness in third-world countries than in industrialized nations. Until now there has been little data regarding the causes, disease course, and options for therapy. Therefore, secondary glaucoma was examined in Paraguay to obtain information on the situation in Latin America. The aim of the study was to explore the causes of secondary glaucoma for programs concerning prevention and therapy. From November 1996 to February 1997 patients with secondary glaucoma were examined at the University Hospital of Asunción, Paraguay. After the clinical examination the secondary glaucomas were classified. Patients with primary glaucoma were included in the same period of time as well in order to get the rate of secondary glaucoma. Altogether 293 patients were examined: 61 with secondary and 232 with primary glaucoma. The causes of secondary glaucoma in 73 eyes were: 20 (27%) with pseudoexfoliation glaucoma, 19 (26%) with post-traumatic glaucoma, 16 (22%) with neovascular glaucoma, 4 (5%) with lens-related glaucoma, 3 (4%) with glaucoma associated with ocular surgery, 2 (3%) with pigmentary and 2 (3%) with corticoid-induced glaucoma. A ratio of 4:1 primary glaucomas to secondary glaucomas was found. The development of special measures for prevention and early therapy is only possible if the causes of this severe disease are explored. The results of this study represent basic information and could help to introduce of prevention programs.

Satellite-based precipitation estimates represent a potential alternative source of input data in a plethora of meteorological and hydrological applications, especially in regions characterized by a low density of rain gauge stations. Paraguay provides a good example of a case where the use of satellite-based precipitation could be advantageous. This study aims to evaluate the version 7 of the Tropical Rainfall Measurement Mission Multi-Satellite Precipitation Analysis (TMPA V7; 3B42 V7) and the version 1.0 of the purely satellite-based product of the Climate Prediction Center Morphing Technique (CMORPH RAW) through their comparison with daily in situ precipitation measurements from 1998 to 2012 over Paraguay. The statistical assessment is conducted with several commonly used indexes. Specifically, to evaluate the accuracy of daily precipitation amounts, mean error (ME), root mean square error (RMSE), BIAS, and coefficient of determination (R 2) are used, and to analyze the capability to correctly detect different precipitation intensities, false alarm ratio (FAR), frequency bias index (FBI), and probability of detection (POD) are applied to various rainfall rates (0, 0.1, 0.5, 1, 2, 5, 10, 20, 40, 60, and 80 mm/day). Results indicate that TMPA V7 has a better performance than CMORPH RAW over Paraguay. TMPA V7 has higher accuracy in the estimation of daily rainfall volumes and greater precision in the detection of wet days (> 0 mm/day). However, both satellite products show a lower ability to appropriately detect high intensity precipitation events.

Stateness and quality of democracy in Paraguay Estatalidad y calidad de la democracia en Paraguay

Full Text Available Taking into account the fact that in all existing indices of the quality of democracy Paraguay fares rather poorly, the author explores how «stateness» accounts for that poor performance. He argues that together with a pattern of truncated modernization that produced an invertebrate society conducive to generalized clientelism and the constitutional and institutional framework that reinforces and perpetuates it, the weakness of the State imposes additional severe constraints. These constraints manifest themselves in two dimensions: the weakness of the state apparatus and its narrow social base in terms of «state-for-the nation or the people».Partiendo de los índices existentes que sitúan al Paraguay entre las democracias de más baja calidad en América Latina, se explora el impacto de la estatalidad en esa baja calidad de la democracia. Se sostiene que, además de la modernización truncada que resultó en una sociedad invertebrada proclive a la proliferación de un clientelismo generalizado y la arquitectura constitucional e institucional que la refuerza y perpetúa, la debilidad del Estado impone limitaciones adicionales muy severas al desarrollo de una democracia de calidad. Estas limitaciones se manifiestan en dos dimensiones: la debilidad del Estado como aparato y su estrecha base social en términos de «Estado-para-la Nación o pueblo».

2001-01-01

The Parana Angola-Namibia igneous province (PAN) is characterized by Early Cretaceous flood tholeiites and tholeiitic dyke swarms associated with alkaline rocks of Early and Late Cretaceous ages, respectively, and with scarce post-Mesozoic magmatic rocks (Comin-Chiaramonti et al., 1997; 1999; Marques et al., 1999). The Eastern Paraguay, at the westernmost side of the Parana Basin, is of special interest because: (1) it is located between two main cratonic blocks, i.e. the southernmost tip of the Amazon Craton, and the northermost exposure of the Rio de La Plata Craton; (2) it was the site of repeated Na-K-alkaline magmatism since Late-Permian-Triassic times (i.e.: 250-240 Ma, Na-alkaline; c. 145 Ma, K-alkaline; 128-126 Ma, K-alkaline; 120-90 Ma, Na-alkaline; 61-33 Ma, Na-alkaline; cf. Comin-Chiaramonti and Gomes, 1996; Comin-Chiaramonti et al., 1999), and of Early Cretaceous tholeiitic magmatism, both low- and high-Ti variants, L-Ti and H-Ti, respectively (133-131 Ma; cf. Marzoli et al., 1999); (3) the younger sodic magmatic rocks are closely associated in space to the potassic analogues (Comin- Chiaramonti et al., 1999). The paper aims discussing the most important Sr- Nd-Pb isotope features of the alkaline and tholeiitic magmas from Eastern Paraguay in comparison with the PAN analogues (au)

The Alto Paraguay Province is located at the border of the State of Mato Grosso do Sul and Paraguay, between the coordinates 21 deg 10{sup `}to 23 deg 25{sup `}of Southern latitude and 57 deg 10{sup `} to 58 deg 00{sup `}, having the city of Porto Murtinho as the main reference point. The geotectonic domain of the area is governed by the precambric units of the Southern extreme of the Amazonic craton which developed a long and accentuated activity, giving rise to folds and important faults, that in several cases seem to have exerted an effective control of the magmatic manifestations. Radiometric data indicate that the emplacement of the syenitic bodies took place in the Permo-Triassic period, with a major incidence in the interval 260-240 Ma, representing thus, an important phase of alkaline magmatic affinity associated to the Parana Basin which is believed is to be unique, since the other known areas (Central, Amambay and Rio Apa Provinces, Paraguay, Velasco Province, Bolivia) are considerably younger (140-120 Ma). Syenitic rocks from the Alto Paraguay Province show wide variation in the ratio {sup 87} Sr/{sup 86} Sr (0.703361 - 0.707734). Excluding the Cerro Boggiani rocks (0.703837-0.707734), values for the nepheline syenites (0.703361-0.703672) general lower than those of the other syenites types. Alkaline syenites cover the interval 0.703510- 0.703872, while quartz syenites and syenogranites are 0.704562 and 0.707076, respectively. geologic evidence, in addition to petrographic, geochemical and isotopic (Sr) data, suggest that the syenitic rocks have been derived from an unique mantelic parental liquid, by fractional crystallization and assimilation processes, which are assumed to be occurred during the emplacement of the magma in the crust.

Full Text Available Organic cotton production in Paraguay. 2. Agronomic limitations for a novel industry. Two main limiting factors to organic cotton production are soil fertility and pest (arthropods and diseases management. Paraguay has begun to produce organic cotton since 2003. An exploratory study was carried out in order to have a better knowledge of the way the organic cotton production has developed and to identify economic (first paper and agronomic limitations (this paper. In addition, this paper provides an analysis of the production of cotton-seed. The study was achieved in 2008 during the cotton harvest period by interviewing the actors from the farm to the industrial level. With more than 200 tons of cotton-seed produced since 2006-2007, Paraguay has reached the second position of South-American producers of organic cotton, behind Peru. In 2007-2008, the recorded average yield of 492 kg.ha-1 of cotton-seed has been underestimated because of sales of organic cotton to the conventional industry. Fertilization and insect pest management, especially for the boll weevil Anthonomus grandis, were based on biological approaches at the whole cropping system level. Management practices included the use of made-in-farm inputs with, according to users, a fair level of efficacy but whose actual effects are mostly poorly known. We recommend in-depth studies firstly to identify the biological pathways involved when necessary, secondly to assess the qualitative and quantitative diversity of farmers practices, and thirdly to integrate their impacts at different space and time scales.

Full Text Available Thoracocharax stellatus (Characiformes, Gasteropelecidae is a small Neotropical species of fish, widely distributed in several rivers of South America. Evidence for karyotype heteromorphysm in populations from different geographical regions has been reported for this species. In this way, populations of T. stellatus from the Paraguay River basin were cytogenetically characterized and the results were compared with other studies performed in the same species but from different basins. The results showed a diploid number of 2n = 54 for T. stellatus, with chromosomes arranged in 6 metacentric (m, 6 submetacentric (sm, 2 subtelocentric (st and 40 acrocentric (a, for both sexes, with a simple Nucleolus Organiser Region (NOR system reported by the techniques of silver nitrate impregnation and fluorescent in situ hybridisation (FISH using 18S rDNA sequences as probe. The distribution of constitutive heterochromatin, observed by the C-band technique and Chromomycin A3 staining showed great similarity among the analyzed populations and consists mainly of discrete blocks in the pericentromeric and telomeric regions of most chromosomes. The presence of female heterogamety was also observed indicating a ZZ/ZW system with W chromosome almost totally heterochromatic. The results also show cytogenetic diversity of the group and are useful to understand the mechanisms of karyotype evolution of the family.

Full Text Available Reported regional wheat yields in Paraguay vary from 1 to 3 t/ha from year to year, but appear not to be correlated with El Niño-Southern Oscillation (ENSO phases. Historical weather data from two locations in representative wheat-growing regions of Paraguay, Encarnación-Itapúa and Ciudad del Este-Alto Paraná combined with crop modeling, were analyzed to optimize nitrogen (N fertilizer application rates according to the ENSO phase of a growing season. The ENSO phase of a growing season was defined based on the average of the sea surface temperature (SST anomalies in the Eastern Equatorial Pacific region for the period June–October using the El Niño region 3.0 index (Niño 3.0. Simulated average yields in Alto Paraná were higher in the drier and cooler La Niña wheat-growing seasons (average of 3.5 t/ha compared to the other phases (average of 3.2 t/ha and in Itapúa, in Neutral seasons (average of 3.8 t/ha compared to the other phases (average of 3.7 t/ha. Accordingly, optimal N fertilizer applications ranged between 20 and 60 kg N/ha between phases depending on the sowing date, soil type and initial amount of soil water content. Applying an ENSO or General Circulation Model (GCM-based forecast for ENSO-season-type specific N fertilizer applications resulted in benefits of >100 US$/ha when compared with current farmers’ practice of consistently low N fertilizer applications in Paraguay. When N management based on forecasts was compared with optimized N application without forecast, the benefits of the forecast was only up to 8 US$/ha. The ENSO-persistence-based forecast showed higher values than the GCM-based forecasts with two lead-times but lower skill. Using climate information can significantly increase current wheat yields and gross margins in Paraguay by tailoring N fertilizer applications to the Niño 3.0-defined ENSO phases, which can be forecasted with moderate skill at the beginning of the growing season.

A mammalian survey was conducted in Mexico (October 1994-January 1996) and in Paraguay (August 1996-March 1997); a complete specimen was collected for each bat in the survey, including primary voucher specimen, ectoparasites, karyotype, and various frozen tissues. The surveys combined provided 937 brain samples (65 bat species) for rabies diagnosis. One male Lasiurus ega, collected in Paraguay, tested positive for the rabies virus (overall prevalence rate of 0.1%). Nucleotide sequence from a 300 bp region of the rabies nucleoprotein gene was compared with sequence obtained from representative rabies virus samples in the repository at the Centers for Disease Control and Prevention (Atlanta, Georgia, USA). Rabies virus extracted from the brain material of L. ega differed by only one nucleotide from a 300 bp consensus sequence (>99% homology) derived from samples for the variant of rabies virus transmitted by Lasiurus cinereus. Lasiurus ego differed by approximately 15% for the variant transmitted by Desmodus rotundus. Phylogenetic analysis found no evidence to suggest L. ego is a reservoir for rabies antigenic variant 6. The most likely explanation for rabies in L. ega was infection following contact with a rabid L. cinereus.

Full Text Available Snakes of the pseudoboine genera Clelia, which is probably polyphyletic, and Boiruna are distributed from southern Argentina, southern Brazil, and Uruguay northwards into central México. Six members occur in Paraguay and Argentina: B. maculata, Clelia bicolor, C. clelia, C. plumbea, C. quimi, and C. rustica. Historically, there has been taxonomic confusion among the larger species (B. maculata, C. clelia, C. plumbea, and C. rustica and between the small species (C. bicolor and C. quimi. All of the species except C. rustica have distinct ontogenetic color changes. Species can be distinguished on the bases of size, color, hemipenial spines, and loreal, supralabial, and ventral scale counts. Much of the morphological evolutionary differentiation in Boiruna and Clelia seems to have taken place in the snout region, as evidenced by the differing proportions of the scales of the loreal region. Boiruna maculata has the widest ecological amplitude. It is broadly distributed in most vegetation types north of the 38th parallel in central Argentina, being absent only from the deltaic sediments of Buenos Aires Province, Argentina and the broad valleys and rolling hills of eastern Paraguay. Clelia bicolor is most common in the Paraguay and Paraná river valleys, with a few records from the Andean foothills in northern Argentina. Clelia clelia is distributed along the Río Paraguay and the lower Paraná, and is also found throughout much of eastern Paraguay. Clelia plumbea is apparently parapatric with C. clelia along the Río Paraná in southeastern Paraguay and Misiones Province, Argentina. The ranges of C. quimi to the east and C. bicolor in the west about in this same region without apparent overlap. There are no vouchered records of Clelia rustica from Paraguay. In Argentina, it is a species of temperate climates; north of the 30th parallel, it occurs in the Andean foothills and the wet forests of Misiones Province. Southwards, it is widely distributed

The Argentine stretch of the del Plata basin crosses regions devoted to extensive and intensive agriculture mostly with chemical pest control. The utilization of pesticides in the region has increased 900% in the last two decades associated with the introduction of biotech crops and direct-seeding techniques. Our objective was to study the occurrence, concentration, and fate of pesticides in surface water and bottom sediments of the principal tributaries and main watercourse of the Paraguay-Paraná River. We sampled 22 sites in the distal positions of the main affluents and main watercourse of the Paraná and report here results from two monitoring campaigns (2010-2012). Surface water and bottom sediments were analyzed according to standardized methods by matrix-solid-phase dispersion and liquid-liquid extraction, respectively. Twenty-three pesticide compounds were analyzed by gas chromatography. The results from both campaigns indicated a generalized but variable distribution in the concentrations detected throughout the basin. The ranges of total measured pesticide concentrations in water and sediments were, respectively, 0.004-6.62 μg/l and 0.16-221.3 μg/kg dry weight. Endosulfans, cypermethrin, and chlorpyrifos were ubiquitous compounds in both environmental compartments and quantitatively the most relevant. All concentrations detected in water were over the recommended guidelines for the protection of aquatic biota. The partitioning indicated a higher affinity for the sediments. Agricultural activity is the source of pesticide-pollution loads, transported by tributaries that reach the main watercourse and alter the quality of the aquatic ecosystem.

Lead concentrations in new enamel decorative paints were determined in three countries in different areas of the world where data were not previously available. The average total lead concentration of the enamel decorative paints purchased in Lebanon, Paraguay and Russia was 24,500ppm (ppm, dry weight), more than 270 times the current limit of 90ppm in Canada and in the United States. Sixty-three percent of these paints contained concentrations greater than 90ppm. Fifty-nine percent contained concentrations greater than 600ppm, the current limit in some countries. The maximum concentrations found were 236,000ppm in Lebanon, 169,000ppm in Paraguay and 52,900ppm in Russia. An average of 29% of the samples contained exceedingly high lead concentrations, >=10,000ppm. Five brands of paint were sampled in each of Lebanon and Paraguay and seven in Russia. Three colors from each brand were analyzed. For five of the six samples of the two brands in Lebanon with affiliations outside the country, the lead concentrations ranged from 1360ppm to 135,000ppm. In Lebanon the maximum concentration in the Egypt-affiliated brand (Sipes) was 135,000ppm and the maximum for the USA-affiliated brand (Dutch Boy) was 32,400ppm. Lead was not detected in any paints from the three of the four brands of paint purchased in Paraguay that had headquarters/affiliations in other countries (Brazil-Coralit), Germany (Suvinil) and USA (Novacor)). Two of the three paints from each of the other Paraguay brands contained high levels of lead with the maximum concentrations of 108,000 and 168,000ppm; one of these brands was manufactured under a license from ICI in the Netherlands. All of the paints purchased in Russia were from Russian brands and were manufactured in Russia. All three paints from one brand contained below detection levels of lead. The maximum levels of lead in the other six brands in Russia ranged from 3230 to 52,900ppm. The two brands with the highest lead concentration, TEKS and LAKRA

2014-01-01

Highlights: • We investigate different transporting modes of hydro-methane, methanol, CO 2 and O 2 . • We determine the best transportation technology from an economic point of view. • The best pathway to distribute the hydro-methane depends on quantity and distance. • Methanol distribution presents the lowest cost delivery. - Abstract: This paper summarizes key results of the analysis of different transport modes of hydro-methane, methanol, carbon dioxide and oxygen in Paraguay, Brazil and Argentina. Hydro-methane is produced in Paraguay and can be used to fuel natural gas vehicles, substituting gasoline and diesel which are at the moment imported from foreign countries. Methanol, also produced in Paraguay, is delivered to Brazil, which is one of the Countries with the highest demand in the region. Oxygen can be sold to Argentina for medical and industrial use. Carbon dioxide is delivered throughout Paraguay. The aim of this study is to determine the best transportation technology from an economic and strategic point of view, minimizing costs associated to products distribution. Several scenarios are investigated; each scenario is associated with different delivery modes. A model is developed to estimate both capital and variable costs for different transportation technologies (pipeline, trucks, ships) in order to choose the lowest-cost delivery mode for each product, depending on distances and flow rates. Four different analysis are performed for each scenario, varying the number of vehicles which must be fueled by hydro-methane and considering its influence on the results. The methodology presented here has a general value, thus it can be easily employed for the economic analysis of different fuels and distribution networks, also placed in different scenarios

Stratigraphy and stable isotope geochemistry of the carbonate sequence from the Paraguay belt

International Nuclear Information System (INIS)

Santos, Roberto Ventura.; Alvarenga, Carlos Jose Souza de; Dantas, Elton Luiz

2001-01-01

Two main Neoproterozoic carbonate sequences occur central Brazil both of which are stratiphicaly above glacial derived sediments. An older carbonate sequence occurs over the Sao Francisco Craton and in the surrounding folded belts (Rio Preto, Aracuai Ribeira and Brasilia). These carbonates overlie glacial diamictites that were related to the 'Sturtian' event dated between 0.7 and 0.9 Ga (Toulkeridis et al. 1999, Santos et al., 2000). A second carbonate sequence is described in the Paraguay Belt and postdated Vendian/Varegian glaciation sediments from the end of the Neoproterozoic. This glacial event has been reported in many studies concerning the Gondwana and the Laurentia supercontinent (Trompette, 1996; Condon and Prave, 2000; Myrow and Kaufman, 1999). In the Paraguay Belt the Vendian- Varangian glaciation rocks are characterized by a glaciomarine sequence, that occur at the border of the basin, and by glacial derived turbidites deposits, that occur in the deeper parts of the basin (Alvarenga and Trompette, 1992). Near the city of Corumba this glaciomarine sequence is overlaid by carbonate rocks containing Ediacaran-like fauna in which has been described Corumbella werneri and Cloudina Lucianoi (Hahn et al., 1982; Walde et al., 1982; Zaine and Fairchild, 1985; 1987). These carbonates have been interpreted as cap carbonates and the age of their fossils have been attributed to the Vendian Superior (590-545 MA) (Alvarenga and Trompette, 1992, Trompette 1996). Isotope stratigraphy studies have been widely used to study cap carbonate rocks that overlie Sturtian and Vendian- Varagian glaciogenic rocks. Stratigraphic correlation of these units is usually difficult because their lack fossils and there is no precise dating method that could be applied to these rocks. Hence, most studies concerning Neoproterozoic carbonates have concentrated on their stromatilites and microfossils content as well as on carbon isotope variations. In the present study, we present new carbon

To assess the challenges in reducing tuberculosis (TB) in prisons in Bolivia, Ecuador, and Paraguay and propose ways to address them through communication interventions. Challenges to two central goals of TB control--early diagnosis of positive cases and successful application of the directly observed treatment, short course (DOTS) strategy--were examined. Data were gathered (through in-depth, structured interviews) and focus groups were conducted in the prisons that housed the largest number of male inmates in each country. Interviewees and focus group participants included program directors, administrative personnel, correctional health and security staff, and incarcerated people who were or had been under treatment for TB and had participated as 'peers' in health services. The findings showed a range of entrenched obstacles for adequate TB control. Stigmatizing attitudes and low knowledge about TB among inmates and key prison personnel discouraged people living in prisons from seeking diagnosis and treatment. Systemic problems in prison health services, along with squalid living conditions, lack of coordination between national TB programs and prison health systems, and insufficient allocation of resources to health prevented the provision of adequate TB prevention and care. In addressing the barriers to effective TB control in prison systems in Bolivia, Ecuador, and Paraguay, a participatory approach to communication is necessary.

Highlights: • We investigate H 2 /O 2 production from large hydraulic plant by water electrolysis. • We produce methanol and hydro-methane from H 2 /O 2 obtained. • We investigate two different configurations of the plant. • We perform a thermo-economic analysis for three scenarios in Paraguay. • We find plants optimal size using a time-dependent thermo-economic approach. - Abstract: A thermo-economic analysis regarding large scale hydro-methane and methanol production from renewable sources (biomass and renewable electricity) is performed. The study is carried out investigating hydrogen and oxygen generation by water electrolysis, mainly employing the hydraulic energy produced from the 14 GW Itaipu Binacional Plant, owned by Paraguay and Brazil. Oxygen is employed in biomass gasification to synthesize methanol; the significant amount of CO 2 separated in the process is mixed with hydrogen produced by electrolysis in chemical reactors to produce hydro-methane. Hydro-methane is employed to supply natural gas vehicles in Paraguay, methanol is sold to Brazil, that is the largest consumer in South America. The analysis is performed employing time-dependent hydraulic energy related to the water that would normally not be used by the plant, named “spilled energy”, when available; in the remaining periods, electricity is acquired at higher cost by the national grid. For the different plant lay-outs, a thermo-economic analysis has been performed employing two different software, one for the design point and one for the time-dependent one entire year optimization, since spilled energy is strongly variable throughout the year. Optimal sizes for the generation plants have been determined, investigating the influence of electricity cost, size and plant configuration

Se sostiene que, además de la modernización truncada que resultó en una sociedad invertebrada proclive a la proliferación de un clientelismo generalizado y la arquitectura constitucional e institucional que la refuerza y perpetúa, la debilidad del Estado impone limitaciones adicionales muy severas al desarrollo de una democracia de calidad. Estas limitaciones se manifiestan en dos dimensiones: la debilidad del Estado como aparato y su estrecha base social en términos de «Estado-para-la Nación o pueblo».

Full Text Available Two new species of Hisonotus are described from the rio Paraná-Paraguay basin in Brazil. The most remarkable features of the new species are the odontodes forming longitudinally aligned rows (one odontode after the other, but not necessarily forming parallel series on the head and trunk (vs. odontodes not forming longitudinally aligned rows, a pair of rostral plates at the tip of the snout (vs. a single rostral plate, the functional v-shaped spinelet (vs. spinelet non-functional, square-shaped, or absent. These features suggest close phylogenetic relationships with Hisonotus bockmanni, H. insperatus, H. luteofrenatus and H. piracanjuba. Additionally, both new species are distinguished from their congeners by characters related to head length and depth, orbital diameter, suborbital depth, caudal peduncle depth, pectoral-fin spine length, snout length and counts of teeth. Hisonotus paresi sp. n. further differs from its congeners bycontrasting dark geometric spots on the anterodorsal region of the body, a character lacking in H.oliveirai sp. n. The variation in number and shape of the rostral plate, posterior rostrum plates, infraorbitals and the preopercle in both new species and in H. insperatus are discussed.

Determine the viability of a remote diagnosis system implemented to provide health care to remote and scattered populations in Paraguay. The study was conducted in all regional and general hospitals in Paraguay, and in the main district hospitals in the country's 18 health regions. Clinical data, tomographic images, sonography, and electrocardiograms (ECGs) of patients who needed a diagnosis by a specialized physician were entered into the system. This information was sent to specialists in diagnostic imaging and in cardiology for remote diagnosis and the report was then forwarded to the hospitals connected to the system. The cost-benefit and impact of the remote diagnosis tool was analyzed from the perspective of the National Health System. Between January 2014 and May 2015, a total of 34 096 remote diagnoses were made in 25 hospitals in the Ministry of Health's telemedicine system. The average unit cost of remote diagnosis was US$2.6 per ECG, tomography, and sonography, while the unit cost of "face-to-face" diagnosis was US$11.8 per ECG, US$68.6 per tomography, and US$21.5 per sonography. As a result of remote diagnosis, unit costs were 4.5 times lower for ECGs; 26.4 times lower for tomography, and 8.3 times lower for sonography. In monetary terms, implementation of the remote diagnosis system during the 16 months of the study led to average savings of US$2 420 037. Paraguay has a remote diagnosis system for electrocardiography, tomography, and sonography, using low-cost information and communications technologies (ICTs) based on free software that is scalable to other types of remote diagnostic studies of interest for public health. Implementation of remote diagnosis helped to strengthen the integrated network of health services and programs, enabling professionals to optimize their time and productivity, while improving quality, increasing access and equity, and reducing costs.

Full Text Available SUMMARY The first Argentinian autochthonous human case of visceral leishmaniasis (VL was confirmed in Posadas (Misiones in 2006. Since then, the disease has increased its incidence and geographical distribution. In the 2006-2012 period, 107 human cases were detected (11 deaths. The presence of Lutzomyia longipalpis was detected in peridomiciles in Puerto Iguazú urban area in 2010; some of these findings were associated with households where cases of canine VL had already been reported. The objective of this study was to ascertain the abundance and spatial distribution of Lu. longipalpis in Puerto Iguazú City, on the Argentina-Brazil-Paraguay border. Lu. longipalpis proved to be exclusively urban and was found in 31% of the households sampled (n = 53, 67% of which belonged to areas of low abundance, 20% to areas of moderate abundance and 13% to areas of high abundance. Nyssomyia whitmani was the only species found both in urban and peri-urban environments, and Migonemyia migonei was registered only on the outskirts of the city. Due to the fact that Puerto Iguazú is considered to be at moderate risk at the moment, it is necessary to intensify human and canine case controls, as well as take integrated prevention and control measures regarding the environment, vectors and reservoirs on the Argentina-Brazil-Paraguay border area.

Paraguay is a bilingual country and knowledge of the guarani language is an important communication tool for the doctor- patient relationship. To determine the degree of and the factors that influence the knowledge of the Guaraní language in medical students at a University Hospital in Paraguay. Observational, cross-sectional, analytical study in which an anonymous questionnaire was applied to the final year medical students of a University Hospital of Paraguay. The baseline characteristics of the medical students and their degree of knowledge of the Guarani language were described. The association between the characteristics of the students and the degree of knowledge of the Guarani language was evaluated with the Chi square association test and the logistic regression model. We included 264 students in the survey. Eighty two percent come from the capital, 72% made their pre-university studies in the capital; 92% studied Guaraní in primary and secondary education; 67.9% do not interpret Guarani correctly; 8.5% understand and express themselves totally in Guaraní. Of these, 86% refer to have the greater learning of the language in their home; 75.2% of respondents believe that primary and secondary education did not help in learning the language. The degree of knowledge of the language (speaks and understands the Guarani language correctly) varies according to: the origin of the student, the inland regions or the capital (31.25% vs. 2.5%, adjusted OR = 0.24, 95% confidence interval: 0.06 to 0.92, p = 0.003); the location of primary and secondary school: inland versus capital (25.6% vs. 1%, adjusted OR: 0.08, 95% confidence interval: 0.01 to 0.53, p = 0.009). The degree of knowledge of the Guaraní language of the students is lower compared to the general population; those who best understand and express themselves were born or studied in the interior of the country.

In this work, it was noticed that populations from these basins have morphological variations between them, indicating a possible geographic isolation. Specimens were studied using twelve morphological characters that were submitted to the canonical variates and body proportion analysis. In the canonical variate analysis, the populations from the Madeira and Paraguay river basins were differentiated by caudal peduncle depth, eye diameter, pre-ventral distance, body height, snout length and head length. In the body proportion analysis, the population of Madeira river basin presented head length, orbital diameter, pre-dorsal distance, dorsal-fin length, pre-ventral distance, body height and caudal peduncle height, smaller than those of the population from Paraguay river basin. These results allowed the recognition of intra-specific variation amplitude, that could become an important instrument for management and conservation of this species. O sauá Tetragonopterus argenteus é endêmico da América do Sul, apresenta ampla distribuição geográfica e ocorre em várias bacias brasileiras, entre elas as dos rios Madeira e Paraguai. Neste trabalho foi observado que as populações dessas bacias apresentam variações morfológicas que, provavelmente, representam isolamento geográfico. Exemplares foram estudados através de 12 caracteres morfológicos e submetidos às análises de variáveis canônicas e de proporções corporais. Na análise das variáveis canônicas, as populações das bacias dos rios Madeira e Paraguai diferenciaram-se pelo diâmetro do olho, distância pré-ventral, altura do corpo, comprimento do focinho, altura do pedúnculo caudal e comprimento da cabeça. Na análise das proporções corporais, a população da bacia do rio Madeira

Full Text Available Background: In Paraguay, little is known about the Afro-descendant population. It is important to know about their nutritional status, mainly in childhood, to guide appropriate action. Objective: To determine the nutritional profile of children under five years from the African descendants’ communities in Paraguay and its associated factors. Material and methods: A cross-sectional and observational design with analytical component was developed. It involved healthy male and female children under five years old, with at least one African descendant as immediate family. Dietary habits and nutritional status (WHO criteria were assessed. WHO Anthro and SPSS 16.0 software were used. Results: 150 children were included. The median of age was 26.9 months (1.2-59.9 m, and 50.7% were males. The median maternal age was 28.3 years (16-49 years. Children with Exclusive Breast Feeding (EBF, n=119 had a mean duration of 3.5±1.8 months (1-7m. 26.9% were exclusively breastfed during six months. The starting of complementary feeding was on average 5.2 months. The underweight prevalence (UW, zP/E 0.05. Children with UW had a lower average of age of onset of complementary feeding (1.7 vs 4.9 months, p˂0.0001 compare with their pairs without malnutrition. Conclusion: Chronic malnutrition was the most prevalent chronic disease affecting over 1 in 10 children. Early initiation of complementary feeding could be a risk factor for malnutrition.

The Chaco Nothura Nothura chacoensis Conover is endemic to the Chaco of western Paraguay. Originally described as a subspecies of the Spotted Nothura N. maculosa (Temminck), it has been regarded by many authorities as a distinct species based on alleged sympatry with N. maculosa. However, an earlier study revealed no differences in cytochrome b sequences between the two taxa. We reanalyzed the geographic distribution and morphological variation of N. chacoensis and N. maculosa in western Paraguay based on museum specimens. There is no locality where specimens of both taxa were collected, thus there is no evidence for sympatry. Morphologically the two taxa did not differ in any size or shape variable. Plumage characters overlapped in a few specimens. We recorded vocalizations from at least four individuals of N. chacoensis within its known range. Its typical territorial song was a very rapid, relatively monotone trill that was virtually identical with the most frequent territorial song of N. maculosa in length, number of notes, rate of notes, and emphasized frequency, and differed substantially from the songs of other species of Nothura. Based on distributional, morphological, biochemical, and especially vocalization data, we conclude that N. chacoensis should be regarded as a subspecies of N. maculosa.

In recent years, changes in climate have entailed variations in surface temperature and precipitation patterns in various countries of the South America, among which Paraguay. Climate change-attributed effects on weather impacts, such as river and urban floods, droughts and heat waves could severely affect the actual conditions of the country. In fact, Paraguay exhibits significant vulnerabilities to climate changes, especially because of its dependence on commodities production (e.g. agriculture, livestock, etc.) and its infrastructural and logistic asset not yet fully formed. In this context, climate change analysis can be an important technical support for practitioners to assist - under uncertainty - national/regional planning, financial resources managing and development (e.g. land-use practices, population growth, economic and community behavior, health, etc.). Moreover, actions in adaptation, disaster risk reduction (DRR), social protection and impacts mitigation may involve high costs if not properly contextualized. The assessment of 21st century climate change and development of whatever response strategies requires climate scenarios at high resolution, including an accurate evaluation of projection uncertainties (i.e. robustness of the analysis). This should ensure adequate insights into the potential impacts of climate change and allow practitioners, usually ill equipped to consider uncertain climate outputs into a broader context (e.g. planning, designing, managing), to make appropriate choices. In the framework of CORDEX initiative, Paraguay is included into the SOUTH-AMERICA-CORDEX one. Three climate simulations over this area are available at the spatial resolution of 0.44° (about 50km), obtained with RCM SMHI-RCA4 (forced by GCMs ICHEC-EC-EARTH and MPI-M-MPI-ESM-LR) and RCM MPI-CSC-REMO2009 (forced by MPI-M-MPI-ESM-LR). Simulations over the 21st century have been performed according with IPCC RCP2.6, RCP4.5 and RCP8.5 scenarios. The plausibility of

Full Text Available El acelerado crecimiento de la población, su conformación por edades y su distribución espacial han despertado en el Paraguay una creciente preocupación pública. Experimentamos una transición demográfica moderada, conformada por las consecuencias de la modernización y el ritmo dispar de los cambios económicos y sociales. Al disminuir la mortalidad y persistir patrones de alta natalidad, se conforma una estructura de edades que consolida el crecimiento demográfico, con un aumento centrado en la población dependiente. A fines de los sesenta se percibió la necesidad de abordar de forma sistemática la problemática de población, principalmente en el marco de la planificación económica, implantando al mismo tiempo la planificación familiar como instrumento de salud pública, antecedente de lo que es hoy salud reproductiva. La percepción de los gobiernos nacionales sobre el tema de población fue y es ambivalente, porque se considera el crecimiento poblacional como un factor siempre positivo, producto de una visión economicista que absolutiza las consecuencias de un mercado interno reducido. La inexistencia de un plan de desarrollo, el déficit de gestión y la insuficiente capacitación tornan dudosa la posibilidad de definir políticas o programas de población orgánicamente articulados, excepto en el ámbito de la salud reproductiva.The population's high growth rate, age profile, and geographical distribution have aroused increasing public concern in Paraguay. The country is involved in a moderate demographic transition, compatible with the consequences of modernity and the uneven rate of both social and economic changes.

Selected trace and minor elements analyzed by XRF in sandstone samples were Rb-Sr-Zr-Nb-Ba-La-Ce-Nd as well as Ti-Mn-Fe with which they are often correlated. Refractory elements like REE are considered useful indicators of geochemical processes and, in this case, of provenance. Usually they maintain their original relationships and are transferred almost directly into sediments. The values here found, absolute and normalized, show correlations among the samples, allowing the establishment of their origin. Most of them in the spidergram patterns display positive spikes of Zr, and negative anomalies at Nb, Sr, Ti: differences in their height/depth could be in relation with the different Series or Formations. Strikingly, spidergrams of samples collected from the Patino Formation show marked negative anomalies interalia of Ba, as well as positive spikes of Nb and Zr, very similar to those found in magmatic specimens from Misiones, Carapegua-Acahay and Alto Paraguay Province and quite different from the other analyzed samples. In addition a remarkable presence of Precambrian signatures were found in the analyzed sandstones from the Paleozoic. (orig.)

Full Text Available AIM: To evaluate the distribution of refractive error in young subjects in a rural area of Paraguay in the context of an international cooperation campaign for the prevention of blindness. METHODS: A sample of 1466 young subjects (ranging from 3 to 22 years old, with a mean age of 11.21±3.63 years old, were examined to assess their distance visual acuity (VA and refractive error. The first screening examination performed by trained volunteers, included visual acuity testing, autokeratometry and non-cycloplegic autorefraction. Inclusion criteria for a second complete cycloplegic eye examination by an optometrist were VA <20/25 (0.10 logMAR or 0.8 decimal and/or corneal astigmatism ≥1.50 D. RESULTS: An uncorrected distance VA of 0 logMAR (1.0 decimal was found in 89.2% of children. VA <20/25 and/or corneal astigmatism ≥1.50 D was found in 3.9% of children (n=57, with a prevalence of hyperopia of 5.2% (0.2% of the total in this specific group. Furthermore, myopia (spherical equivalent ≤-0.5 D was found in 37.7% of the refracted children (0.5% of the total. The prevalence of refractive astigmatism (cylinder ≤-1.50 D was 15.8% (0.6% of the total. Visual impairment (VI (0.05≤VA≤0.3 was found in 12/114 (0.4% of the refracted eyes.

Historical records of Ateles chamek (black-faced black spider monkey) suggest that the species range extends further south of the known species distribution, within an ecotonal region between the Amazonia, Cerrado and Pantanal biomes in Brazil. Ecotones are zones of habitat transition with high species richness that remain undersampled as conservationists often prioritize biodiversity hotspots. Thus, distribution ranges may be inaccurately measured when species occur in ecotonal zones. We report the first precise records of A. chamek in 24 new localities surveyed in the ecotonal zone of the Upper Paraguay River Basin, and we present subgroup encounter rates in the 11 largest patches (>70 ha) along 207 km of the line transects surveyed. The new records represent an expansion of the distribution of A. chamek approximately 200 km to the south, increasing the known extent of its occurrence by 10.8%. Local tributaries may not be barriers for spider monkeys, which are able to swim and cross slow-moving rivers. However, the dry forests of the Cerrado and the flooded areas of the Pantanal, formed by grassland and scarce trees, may be habitat barriers for A. chamek. The populations living in this ecotonal zone are relatively abundant (1.1-6.67 subgroup sightings/10 km) compared to the heavily hunted continuous forests of northern Amazonia. Furthermore, these values are similar to those for other Ateles spp. inhabiting forests with low or no hunting pressure. We highlight the need for specific conservation action to protect the spider monkeys living in these landscapes, which are threatened by agriculture expansion.

Trypanosoma cruzi II is associated with Chagas disease in the southern part of South America. We analyzed T. cruzi variants in field-collected triatomines and congenitally infected infants living in the same disease-endemic region in Paraguay. Results of polymerase chain reactions for T. cruzi kinetoplast DNA and satellite DNA were positive in 83 triatomine feces samples and 58 infant blood samples. However, lineages were detected in 33 and 38 samples, respectively. Trypanosoma cruzi genotypes were determined in 56 (97%) blood samples after hybridization by using specific probes. The Tc I genotype was not detected. The prevalent sublineage was Tc IId in triatomines (27 of 33) and infant blood (36 of 58) as assessed by amplification of the 24Salpha ribosomal RNA and the mini-exon region genes. The Tc IIc genotype was detected in 20 infant blood samples and in 1 triatomine. This study shows T. cruzi II is the predominant lineage circulating in triatomines and humans in endemic areas of eastern region of Paraguay.

Full Text Available In order to select soil management practices that increase the nitrogen-use efficiency (NUE in agro-ecosystems, the different indices of agronomic fertilizer efficiency must be evaluated under varied weather conditions. This study assessed the NUE indices in no-till corn in southern Paraguay. Nitrogen fertilizer rates from 0 to 180 kg ha-1 were applied in a single application at corn sowing and the crop response investigated in two growing seasons (2010 and 2011. The experimental design was a randomized block with three replications. Based on the data of grain yield, dry matter, and N uptake, the following fertilizer indices were assessed: agronomic N-use efficiency (ANE, apparent N recovery efficiency (NRE, N physiological efficiency (NPE, partial factor productivity (PFP, and partial nutrient balance (PNB. The weather conditions varied largely during the experimental period; the rainfall distribution was favorable for crop growth in the first season and unfavorable in the second. The PFP and ANE indices, as expected, decreased with increasing N fertilizer rates. A general analysis of the N fertilizer indices in the first season showed that the maximum rate (180 kg ha-1 obtained the highest corn yield and also optimized the efficiency of NPE, NRE and ANE. In the second season, under water stress, the most efficient N fertilizer rate (60 kg ha-1 was three times lower than in the first season, indicating a strong influence of weather conditions on NUE. Considering that weather instability is typical for southern Paraguay, anticipated full N fertilization at corn sowing is not recommended due the temporal variability of the optimum N fertilizer rate needed to achieve high ANE.

Full Text Available Hypostomus cochliodon group is a monophyletic clade of 20 valid species of Neotropical armored catfishes that is widely distributed throughout South America. Recently, specimens identified as H. cochliodon from the type locality and nearby localities were examined, and found to include representatives of more than one species. A redescription of H. cochliodon is provided, with a description of two new species, one from the Bodoquena Plateau and another from several localities of the rio Paraguay basin. A lectotype for H. cochliodon is designated herein, since the previous designation is invalid. Hypostomus cochliodon is diagnosed from all other species of the H. cochliodon group by having the opercle almost completely covered laterally by thick layer of skin, the absence of buccal papilla, weak to moderately developed keels on the lateral plates of the body and by the color pattern of its body and fins. Hypostomus basilisko, new species, is distinguished from the remaining species of the H. cochliodon group by the absence of spots on the body, highly developed keels and spoon-shaped teeth. Hypostomus khimaera, new species, is distinguished from the other species of the H. cochliodon group by having a dark tan stripe along the midline of the flank, black spots on the body and/or fins and teeth with mesial cusp and not spoon-shaped.

Full Text Available Research indicates that preschool children need to learn pre-math skills to build a foundation for primary- and secondary-level mathematics. This paper presents the results from the early stages of a pilot mathematics program implemented in Cordillera, Paraguay. In a context of significant gaps in teacher preparation and pedagogy, the program uses interactive audio segments that cover the entire preschool math curriculum. Since Paraguayan classrooms tend to be bilingual, the audio and written materials use a combination of Spanish and Guaraní. Based on an experimental evaluation since the program’s implementation, we document positive and significant improvements of 0.16 standard deviations in standardized test scores. The program helped narrow learning gaps between low- and high-performing students, and between students with trained teachers and those whose teachers lack formal training in early childhood education. Moreover, the program improved learning equally among both Guaraní- and Spanish-speaking students. But not all learning gaps narrowed as a result of the program. Although girls improved significantly, boys improved much more, ultimately increasing the gender gap. To close this gender gap, the program has been modified to encourage girls’ increased participation in the classroom and general interest in math

MAYKELL LEITE DA COSTA

2011-01-01

Full Text Available Soybean is today the most traded commodity in the global market. Soy is a plant of great importance to human nutrition, animal feed and industries. Based on research efforts conducted in the main soy producing region in Paraguay, the study aimed to characterize the agents involved in the national soy industry and present an overview of the relations between them, particularly between business companies and farmers, with emphasis on small farmers. Emphasis will be given to contractual relations and how they impact the activity. The results indicate that contractual arrangements, formal or not, are tools that contribute to stable relations between the parties, especially in a business so dependent on exogenous factors, as is the case of agriculture. Therefore, it is crucial that the public and/or private organizations encourage the use of contracts to reduce costs and keep the agents in the productive activity.

Full Text Available This work tries to contribute to fill up an emptiness on the study of the population of African origin and, generally, slave in an area in which, traditionally, its presence was even refused. The interest is focused on the process of evangelization carried out by the jesuits, because they were they who took care primarily of such ministry between the slaves. Firstly, are studied some canonical problems, considered by the Church and the jesuits, around the baptism and catechizing of the enslaved population; next, the fundamental aspects of this practice are reviewed based on the documentation shown in the Anuas Letters of the Jesuit Province of Paraguay.

Este trabajo intenta contribuir a rellenar un vacío sobre el estudio de la población de origen africano y, por lo general, esclava en un área en la que, tradicionalmente, se negaba incluso su presencia. El interés recae sobre el proceso de evangelización llevado a cabo por los jesuitas, pues fueron ellos quienes se ocuparon prioritariamente de tal ministerio entre los esclavos. Primeramente, se ponen de relieve algunos problemas canónicos que se planteó la Iglesia, y en particular los jesuitas, en torno al bautismo y catequización de la población esclava; a continuación, se revisan los aspectos fundamentales de la práctica catequética: medios utilizados, aprendizaje de lenguas, creación de cofradías, etc., tomando como documentación de base las Cartas Anuas de la Provincia Jesuítica del Paraguay.

The Government in Paraguay approved by Decree Law 10754, dated October 6, 2000, its National Regulation on Basic Safety Standards for Radiation Protection and the Safety of Radiation Sources, based on the IAEA Safety Standards 115. The primary goal of Patient Protection is to ensure that both Regulatory Authorities and all Responsible parties in Medical Practices observe procedural process in conducting their responsibilities on regulatory and administrative affairs. On one side the Government, 'Department de Proteccion Radiologica', under the Health Ministry and Comision Nacional de Energia Atomica, and on the other side, the medical practitioner who prescribes or conducts diagnostic or therapeutic treatment, both ensure that the exposure of patients be the minimum. This document describes how the Regulatory Authorities intend to implement this recent act and on the other hand take the advantage of this Conference to understand better this subject, especially on the following subjects: essential requirement for licensing, inspection and enforcement programme in the country's capital and in the interior, where there are more difficulties; workers and medical training and lessons learned applying to developing countries.

Trypanosoma cruzi II is associated with Chagas disease in the southern part of South America. We analyzed T. cruzi variants in field-collected triatomines and congenitally infected infants living in the same disease-endemic region in Paraguay. Results of polymerase chain reactions for T. cruzi kinetoplast DNA and satellite DNA were positive in 83 triatomine feces samples and 58 infant blood samples. However, lineages were detected in 33 and 38 samples, respectively. Trypanosoma cruzi genotypes were determined in 56 (97%) blood samples after hybridization by using specific probes. The Tc I genotype was not detected. The prevalent sublineage was Tc IId in triatomines (27 of 33) and infant blood (36 of 58) as assessed by amplification of the 24Sα ribosomal RNA and the mini-exon region genes. The Tc IIc genotype was detected in 20 infant blood samples and in 1 triatomine. This study shows T. cruzi II is the predominant lineage circulating in triatomines and humans in endemic areas of eastern region of Paraguay. PMID:20207861

La fertilización nitrogenada eleva los rendimientos en suelos pobres en este nutriente, pero su eficiencia aún no es bien conocida. En el estudio se utilizó la técnica isotópica para determinar el destino del N aplicado a un cultivo de sésamo. En el campo experimental de la Facultad de Ciencias Agrarias de la Universidad Nacional de Asunción, Paraguay, en un diseño experimental de bloques completos al azar se estudió la eficiencia en la aplicación de N como fertilizante y abono verde (lupino + avena negra con y sin laboreo del suelo. El N fue aplicado como urea-15N (5% enriquecimiento a razón de 50 kg/ha. Los resultados mostraron contenidos (kg/ha de N en granos (84, materia seca (104 y suelo hasta 15 cm (938. El 20% del N aplicado fue absorbido por la planta, 42% permaneció en el suelo y 38% no pudo contabilizarse y posiblemente se perdió por lixiviación y volatilización. La técnica de dilución isotópica fue útil para determinar el destino del N aplicado, pero sobreestimó el aporte de los abonos verdes en el contenido de N en el suelo.

2007-06-01

Full Text Available The taxonomic revision of the Sterculiaceae family in Paraguay is presented here, including 56 species and 4 varieties, a total of 59 taxa three of which are endemic. They belong to 7 genera, the same that grow in Argentina, with a variable number of species, ranging from 1 like in Sterculia and Guazuma to 16 such as Byttneria andMelochia. The family is distributed along all the area in very diverse habitats, like gallery forests, fertile lands, but also on calcarate, saltpetrous or sandy soils. The habit is generally shrubby to sub-shrubby, rarely arborescent or climbing. The plants are unarmed or spinose such in some Byttneria species. The project to revise this family stimulated the attention in the field work. As result was foundAyenia magna, member of the section Cybiostigma. Its more southern area was Trinidad in the coast of Venezuela, and now it has been found at Cerro León, in the north of western Paraguay. Another interesting finding is Ayenia spinulosa, which has been only known by the type specimen. This species grows on calcarate soils of the Concepción department. A generous amount of specimens make possible that this taxa can be represented in many herbaria of the world. The Sterculiaceae flowers are always small, usually agglomerate at the leafs axils, and in many cases morphologically complex. The petals are reddish or violet, rarely yellow like inWaltheria, or white. In Melochia it can be longistyle, brevistyle or mesostyle. The leaves are petiolate, estipulate, with stellate, single or glandular hairs. The appearance of the plants and the indument are similar to many Malvaceae, due to which it is necessary to examine this family at the herbaria. The anthers are dithecal and enlarged in Sterculiaceae, while in Malvaceae are monothecal and rounded. The text includes the description, synonymy and illustration of each taxon, keys to distinguish each one and its geographic distribution represented on 11 maps. The

Full Text Available The 1992 Constitution recognizes the existence of people prior to the formation of the Paraguayan State and in that sense it gives them certain rights that protect their territory, identity and culture. This declaration of purpose constitutes a break with the previous model of dominant and exclusionary state policies toward indigenous peoples. However, the rights of indigenous peoples continue without respected, in spite of the space won in terms of social and political organizations, the struggle continues in this constant «search of the land without evil». This paper aims to describe the current situation of indigenous peoples from an analysis of access to public services, economic status, employability, employment discrimination and public policy. It also attempts to explain the factors that have influenced in the lack of consolidation of the indigenous movement in Paraguay.La Constitución Nacional de 1992 reconoce la existencia de pueblos anteriores a la conformación del Estado paraguayo y, en ese sentido, les otorga una serie de derechos que protegen sus territorios, identidad y cultura. Esta declaración de intenciones constituye un quiebre con respecto al modelo anterior de políticas estatales dominantes y excluyentes hacia los pueblos indígenas. No obstante, los derechos de los pueblos indígenas siguen sin respetarse, y a pesar de los espacios ganados en cuanto a organizaciones sociales y políticas, la lucha continúa en esa búsqueda constante de la tierra sin mal. Este trabajo busca describir la situación actual de los pueblos indígenas a partir de un análisis del acceso a los servicios públicos, la situación económica, la empleabilidad, la discriminación laboral y las políticas públicas. Asimismo, intenta explicar los factores que han influido en la escasa consolidación del movimiento indígena en Paraguay.

Full Text Available Organic cotton production in Paraguay. 1. Some economic limitations for a novel industry. Paraguay, whose small farmers are traditionally cotton growers, has begun to crop and process organic cotton since 2003. An exploratory study was carried out in order to have a better knowledge of the way the organic cotton production has developed and to detect eventual economic limitations. The study was achieved in 2008 during the cotton harvest period by interviewing the actors from the farm to the industrial level. The organic cotton industry was built by a single company in a favorable national (20 years of organic production for a diversity of crops and international (an increasing demand for organic products, including cotton context. This single company applied a strategy of creating alliances with NGOs, public authorities and other private operators, in order to increase farm production – by adding new farmers – and textile manufacture and trade worldwide. We detected three kinds of economic limitations. Firstly, organic cotton production still remained largely dependent on the conventional cotton industry for the supply of seed. Secondly, the cumbersome certification process at farm level and its cost associated with increased logistic problems derived from the increase in geographical dispersion of small producers appeared to seriously limit the possibilities for expansion. Thirdly, although the price paid for organic cotton was 12-14% higher in 2008, the obligation for the farmers to sell drier cotton and a longer buying process resulting in delayed cash payments led many farmers to sale a large part of their organic cotton to conventional buyers. We recommend in-depth studies on these three topics to acquire a better knowledge of their extent in terms of intensities and variations, and to propose measures to mitigate them.

At the triple border Brazil/Paraguay/Argentina there is easy mobility from one city to another for economic and tourism activities. This constant and fast population mobility is mainly to visit Iguazu Falls, in the Iguazu River, on the border of the Brazilian state of Paraná and the Argentina. As the incidence of tuberculosis is high in this setting, our study aimed to establish a first baseline of circulating genotypic lineages of Mycobacterium tuberculosis. This study included 120 patients from 10 cities in southwestern Paraná, Brazil with pulmonary symptoms, from July 2009 to July 2011. Information about sex, age, clinical features and address was collected by reviewing the national tuberculosis notification database. Of these, 96 (80%) isolates were identified as M. tuberculosis and 22 (22.9%) were drug resistant (20, 20.8% INH mono-resistant and 2, 2.1% multidrug-resistant). All isolates were subjected to genotyping by Spoligotyping and MIRU-VNTR typing. The distribution of the isolates analyzed by spoligotyping revealed 30 distinct patterns. The four mainly detected clades were Latin American and Mediterranean (LAM), ill-defined T, Haarlem (H) and S. The MIRU-VNTR showed 85 distinct patterns. Spoligotyping combined to MIRU-VNTR allowed 90 distinct patterns. Our study demonstrated that there is significant molecular diversity in circulating M. tuberculosis, with predominance of the LAM and T clades in cities of southwestern Paraná, Brazil, bordering Argentina and Paraguay.

According to the IAEA-TECDOC-1312, as it is required by international agreements, the displacement of radioactive material within and among States should be subject to strict regulatory, administrative, safety and technical controls to ensure conditions of technological and physical safety. The Customs Office is one of the institutions responsible for monitoring shipments crossing international borders. Increasing illicit trafficking of radioactive materials, the use of ionizing radiation generating equipment for checking loads, and trade in radioactive substances have informed the need for education in radiation protection of customs officials. Thus, based on a course on radiation protection for Customs officials, organized by the International Atomic Energy Agency, in March 2008 was initiated a course of radiation protection, of 30 hours Carrera Tecnica del Centro de Formacion y Capacitacion Aduanera de Paraguay, which highlights the basic chapters and for transporting, nomenclature, new equipment emitting ionizing radiation and smuggling. Since then, to date, at least 10 groups have completed the training. Within the training program for customs officials, was incorporated a course for radiation protection of operators of baggage scanners with a four-hour program. Finally, since from 2011 and periodically, at various country customs, a workshop on Illicit trafficking of radioactive and nuclear materials is performed. The results of these courses have been very positive, as well as know the proper procedures for dealing with ionizing radiation has increased the safety culture within the institution.

Understanding effects of habitat loss and fragmentation on populations or communities is critical to effective conservation and restoration. This is particularly important for bats because they provide vital services to ecosystems via pollination and seed dispersal, especially in tropical and subtropical habitats. Based on more than 1,000 h of survey during a 15-month period, we quantified species abundances and community structure of phyllostomid bats at 14 sites in a 3,000-km2 region of eastern Paraguay. Abundance was highest for Artibeus lituratus in deforested landscapes and for Chrotopterus auritus in forested habitats. In contrast, Artibeus fimbriatus, Carollia perspicillata, Glossophaga soricina, Platyrrhinus lineatus, Pygoderma bilabiatum, and Sturnira lilium attained highest abundance in moderately fragmented forest landscapes. Forest cover, patch size, and patch density frequently were associated with abundance of species. At the community level, species richness was highest in partly deforested landscapes, whereas evenness was greatest in forested habitat. In general, the highest diversity of bats occurred in landscapes comprising moderately fragmented forest habitat. This underscores the importance of remnant habitat patches to conservation strategies.

Full Text Available Within the framework of growing concern for analyzing the quality of young democracies, this article focuses on the Paraguayan case. A democracy sometimes neglected by the academic literature. However, Paraguay is drawing attention as a consequence of Colorado’s Party defeat (in office since 1947 in the 2008 presidential election. A theoretical and methodological thinking about the concept of the quality of democracy together with an empirical research have been done in this article. Five essential dimensions have been taken into consideration: political rights and civil liberties; rule of law; accountability; responsiveness and political participation. The main conclusion is that Paraguay has a low quality democracy, far away from the rest of Latin American countries. This statement is backed up by three different explanations that are, at the same time, interlinked. These are the following: socioeconomic factors, features of its own political institutions (above all, the widespread clientelism and, finally, political parties’ interests and strategies.En el marco de una preocupación cada vez mayor por analizar la calidad de las nuevas democracias, este artículo se ocupa de examinar el caso de Paraguay. Se trata de una democracia poco atendida en la literatura especializada aunque su interés está creciendo como consecuencia de la derrota electoral del Partido Colorado (en el poder desde 1947 en las presidenciales de abril de 2008. Para llevar a cabo este trabajo, se parte de una reflexión teórica y metodológica en torno a la noción y la medición empírica de la calidad democrática. Al realizar el análisis de la democracia paraguaya se atiende a cinco dimensiones fundamentales: derechos políticos y libertades civiles, Estado de Derecho, rendición de cuentas, responsiveness y participación. La conclusión general es que es una democracia de baja calidad, distanciada del promedio latinoamericano. Para explicar este bajo nivel de

Full Text Available Although Spanish and Portuguese coexist in several areas of America, almost all studies have focused on the contact situation in the North of Uruguay, and this contact has been hardly considered from a historical point of view. This work tries to mitigate this lack of knowledge in presenting several texts from Paraguay in the 18th century, which show a clear influence from Portuguese. A philological edition of such documents is provided here and a study of linguistic characteristics possibly due to Portuguese influence is made. Our aim is twofold: 1 to describe the linguistic variety used in these written texts in comparison with the synchronic and diachronic data which are already available regarding the Portuguese Dialects in Uruguay (DPU and some other areas; 2 to provide data which could be helpful to understand the idiosyncratic characteristics of the linguistic contact of these two Romance languages and the significance of Portuguese in the shaping (of some linguistic varieties of American Spanish.

Full Text Available According to Latinobarómetro, political parties are the institutions which less confidence receive from Latin Americans. This is not a particularity of Latin America, but a documented problem of Western consolidated democracies.In this context, in Europe and United States, among others, the use of digital media become a tool to overcome the crisis of representation, given their capacities to renovate politics, and because they allow the offering of more publicity of public matters as well as the opening up of new channels of participation and communication between citizens and representatives. But to what extent and with which features is this adoption happening in Latin America? Based on the study of the online presence of political parties and deputies of Argentina, Paraguay and Uruguay (webs, blogs, Facebook and Twitter, this article explores the levels of digital media adoption and the influence of variables such as the internet diffusion in the country, the crisis of representation and the characteristics of political parties (institutionalization, ideology, size, role of leaders explaining the extension and characteristics of this adoption.

Full Text Available The Word offers us a critical glance about the economic and socio-cultural impacts of the transgenic crops in peasant and indigenous communities of the eastern region of Paraguay, it is given special attention to the use of Roundup, with the undoubted environment cost and the uncertain risks to human and animal health. The impacts and interactions that the techno-commoditization of the organisms genetically modified OGM have on the affected populations and the environment-species, soil, water, woods, flora, fauna is discussed in the Word.The extent of use of glyphosate on transgenic crops would involve not only the environment of the crop, but go to generate profound cultural changes, technological, of management, environmental, economical, social and legal, whose effects we already see them come with the decline of peasant and indigenous communities, that at not finding adequate strategies to face them, collapse as collectivity. The Word contains important elements to renew the debate and the critical thought in relation to the problematic of transgenic crop and its impact in indigenous and peasant populations.

Bordon, Oscar

2013-01-01

According to the IAEA-TECDOC-1312, as it is required by international agreements, the displacement of radioactive material within and among States should be subject to strict regulatory, administrative, safety and technical controls to ensure conditions of technological and physical safety. The Customs Office is one of the institutions responsible for monitoring shipments crossing international borders. Increasing illicit trafficking of radioactive materials, the use of ionizing radiation generating equipment for checking loads, and trade in radioactive substances have informed the need for education in radiation protection of customs officials. Thus, based on a course on radiation protection for Customs officials, organized by the International Atomic Energy Agency, in March 2008 was initiated a course of radiation protection, of 30 hours Carrera Tecnica del Centro de Formacion y Capacitacion Aduanera de Paraguay, which highlights the basic chapters and for transporting, nomenclature, new equipment emitting ionizing radiation and smuggling. Since then, to date, at least 10 groups have completed the training. Within the training program for customs officials, was incorporated a course for radiation protection of operators of baggage scanners with a four-hour program. Finally, since from 2011 and periodically, at various country customs, a workshop on Illicit trafficking of radioactive and nuclear materials is performed. The results of these courses have been very positive, as well as know the proper procedures for dealing with ionizing radiation has increased the safety culture within the institution

The Quaternary alluvial systems tract of the Pantanal Basin, Brazil

Directory of Open Access Journals (Sweden)

Mario Luis Assine

Full Text Available ABSTRACT The Pantanal Basin is an active sedimentary basin in central-west Brazil that consists of a complex alluvial systems tract characterized by the interaction between different river systems developed in one of the largest wetlands in the world. The Paraguay River is the trunk river system that drains the water and part of the sediment load received from areas outside of the basin. Depositional styles vary considerably along the river profiles throughout the basin, with the development of entrenched meandering belts, anastomosing reaches, and floodplain ponds. Paleodrainage patterns are preserved on the surface of abandoned lobes of fluvial fans, which also exhibit many degradational channels. Here, we propose a novel classification scheme according to which the geomorphology, hydrological regime and sedimentary dynamics of these fluvial systems are determined by the geology and geomorphology of the source areas. In this way, the following systems are recognized and described: (I the Paraguay trunk-river plains; (II fluvial fans sourced by the tablelands catchment area; (III fluvial fans sourced by lowlands; and (IV fluvial interfans. We highlight the importance of considering the influences of source areas when interpreting contrasting styles of fluvial architectures in the rock record.

Qualitative Methodology of production of field diaries of a normal day. Primary Heath Care of Toledo and Tenerife in Spain, and Paraguay, Mexico, and Peru. Non-random sampling, intentional, followed by snowball sample until data saturation. Participants wrote a diary of a typical day's work, their circumstances and socio-health context, and were studied by content analysis. Techniques to control the biases were used the check the participants and the triangulation between the obtained results and the existing bibliography, and data found on the Internet daily. We performed a mental map to transcribe the results graphically and in a comprehensive form. A total of 24 diaries of a normal day were obtained (9 doctors in Spain, 7 in Mexico, 4 in Paraguay, and 4 in Peru). We found some similarities, but many differences between countries. In contexts of humble but spirited, rural, with traditional roots and undemanding, there was a wider range of tasks of the family doctor, the coexistence of public and private work, and modern and traditional medicine, with greater presence of family and community care, more physician satisfaction and better patient-physician relationship.

Ningún encuestado cumple con las recomendaciones de lavado y manipulación de alimentos. Es preocupante el alto porcentaje de adultos que no cumple las recomendaciones, agravado por la no intención de cambio. Por lo tanto, se puede concluir que el objetivo inicial de las guías alimentarias del Paraguay de orientar a la población sobre los estilos de vida adecuados no se cumple. Debido a esto, se debe promover la revisión del medio de implementación de las mismas para alcanzar a un sector mayor de la población, y así lograr la adopción de mejores estilos de vida.

In Paraguay, pesticides are the causative agent in 13.7% of poisonings, especially organophosphorus compounds. Such poisoning produces the inhibition of acetylcholinesterase generating three possible clinical conditions: acute poisoning, intermediate syndrome or late neurotoxicity. We present 15 cases of acute poisoning, ten women and five men from a rural community between 5 and 67 years of age, whose symptoms began after using water contaminated by pesticides from the community network. The most common symptoms were nausea and vomiting, followed by abdominal pain, headache, fever, itching, red eyes and sweating. Five patients underwent blood tests for blood count, renal and liver function and serum cholinesterase, with results within the reference values; just one patient had high liver enzymes.In two samples from the community water supply network the active compound detected was profenophos. It is essential to train primary health care personnel to identify cases of acute pesticide poisoning in a timely manner to provide appropriate treatment, especially in rural areas. Additionally, it is necessary that responsible institutions monitor compliance with environmental regulations in these areas to avoid such incidents.

Full Text Available From the end of the nineteenth century until the middle of the twentieth, the Gran Chaco was a zone of conflict. Argentina, Bolivia and Paraguay exercised varied and competing influences in the region, reflecting the intentions of each nation to incorporate the Chaco forcibly as part of larger projects of industrialisation and colonisation. This study examines the implementation of these projects, as well as the resistance they generated in the face of the violence visited upon the inhabitants of the region, whether indigenous peoples, mestizos, or whites. From an anthropological perspective, the work also reassesses conflicts in the Chaco region as a problem in the history of inter-American relations, where non-governmental actors determine links between people and government. The article goes on to consider the national and regional contexts to conflict, in which frontiers and boundaries are further concepts and realities to be assessed.

Desde fines del siglo XIX y hasta mediados del XX, el Gran Chaco constituyó, en procesos asimétricos ejercidos por los estados que terminaron dividiéndose su jurisdicción, la Argentina, Bolivia y Paraguay, una región de disputas, que incluyó guerras, militarización de límites, forzada incorporación en los desarrollos industrializadores y colonizadores. Este trabajo busca conocer la ejecución de aquellas políticas y las resistencias generadas, en espacios que fueron tanto de concertaciones, como de conflictos frente al poder y a la violencia ejercida sobre sus pobladores, indios, mestizos y blancos. El objetivo es también contribuir a enriquecer la historia de las relaciones interamericanas, a través de una perspectiva antropológica, en donde actores no estatales configuran vínculos entre pueblos y gobiernos, y asimismo de una mirada que se dirija simultáneamente hacia la consideración de los contextos nacionales y regionales, en donde fronteras y límites son nociones y realidades a

Erosion rates and landscape evolution of the lowlands of the Upper Paraguay river basin (Brazil) from cosmogenic 10Be

The importance of Earth's low sloping areas in regard to global erosion and sediment fluxes has been widely and vigorously debated. It is a crucial area of research to elucidate geologically meaningful rates of land-surface change and thus the speed of element cycling on Earth. However, there are large portions of Earth where erosion rates have not been well or extensively measured, for example, the tropical lowlands. The Cuiabana lowlands are an extensive low-altitude and low-relief dissected metamorphic terrain situated in the Upper Paraguay river basin, central-west Brazil. Besides exposures of highly variable dissected metamorphic rocks, flat residual lateritic caps related to a Late Cenozoic planation surface dominate interfluves of the Cuiabana lowlands. The timescale over which the lowlands evolved and the planation surface developed, and the rate at which they have been modified by erosion, are poorly known. Here, we present measurements of in situ produced cosmogenic 10Be in outcropping metamorphic bedrock and clastic-lateritic caps to quantify rates of erosion of the surface and associated landforms in order to better understand the Quaternary landscape evolution of these lowlands. Overall, slow erosion rates (mean 10 m/Ma) suggest a stable tectonic environment in these lowlands. Erosion rates vary widely between different lithologies (range 0.57 to 28.3 m/Ma) consistent with differential erosion driving regional landform evolution. The lowest erosion rates are associated with the low-relief area (irregular plains), where clastic-laterite (mean 0.67 m/Ma) and quartzite (mean 2.6 m/Ma) crop out, whereas the highest erosion rates are associated with dissection of residual hills, dominated by metasandstone (mean 11.6 m/Ma) and phyllite (mean 27.6 m/Ma). These data imply that the Cuiabana lowland is comprised of two dominant landform sets with distinct and different dynamics. Because the planation surface (mostly lowlands) is lowering and losing mass more

Distributions and phylogeographic data of rheophilic freshwater fishes provide evidences on the geographic extension of a central-brazilian amazonian palaeoplateau in the area of the present day Pantanal Wetland

Alexandre C. Ribeiro

Full Text Available The analysis of the distribution patterns presented by examples of freshwater fishes restricted to headwater habitat: the anostomid Leporinus octomaculatus, the characins Jubiaba acanthogaster, Oligosarcus perdido, Moenkhausia cosmops, Knodus chapadae, Planaltina sp., the loricariid Hypostomus cochliodon, and the auchenipterid Centromochlus sp. provided evidences of a relatively recent shared history between the highlands of the upper rio Paraguay and adjoining upland drainage basins. Restricted to headwater of the uplands in the upper rio Paraguay and adjoining basins, these species provide biological evidence of the former extension of the central Brazilian plateau before the origin of the Pantanal Wetland. Disjunction took place due to an ecological barrier to these rheophilic taxa represented tectonic subsidence related to the origin of the Pantanal Wetland. Molecular analysis of Jubiaba acanthogaster revealed that the sample from the upper rio Xingu basin are the sister-group of a clade that includes samples from the upper rio Arinos (upper rio Tapajós plus the upper rio Paraguay basin, supporting the assumption that the origin of the upper rio Paraguay basin causing vicariance between this basin and the upper rio Tapajós is the least vicariant event in the evolutionary history of the group.

K-Ar ages of alkaline rock from Southern Brazil and Eastern Paraguay: compilation and adaptation of new decay constants

Sonoki, I.K.; Garda, G.M.

1990-01-01

A compilation of 295 geochronological data of 52 alkaline occurrences from Southern Brazil and Eastern Paraguay is presented. These data, mostly available in previous publications, were recalculated, using the new constants recommended by STEIGER and JAEGER (1977) for the K-Ar method. The estimated analytical error of the age determined using experimental parameters is also indicated (COX and DALRYMPLE, 1967). This paper aims, specifically, at making ages published prior to 1977 compatible with recent data, allowing, for example, comparisons between ages obtained from a single alkaline massif or from neighbouring massifs. By calculating K-Ar ages using the constants recommended by STEIGER and JAEGER (op. cit.), there occurs an increase of 2.1 to 2.4% in the value of the age calculated with the previous constants.

Paraguay has registered no human cases of rabies since 2004, and the last case in dogs, reported in 2009, was due to a variant maintained in the common vampire bat "Desmodus rotundus". In 2014, a dog was diagnosed as positive for rabies with aggression towards a boy and all required measures of control were successfully adopted. Epidemiological investigation revealed that the dog was not vaccinated and had been attacked by a crab-eating fox, "zorro" (Cerdocyon thous). The sample was diagnosed by the Official Veterinary Service of the Country and sent to the Center on Rabies Research from the University of São Paulo, Brazil, for antigenic and genetic characterization. A second sample from a dog positive for rabies in the same region in 2015 and 11 samples from a rabies outbreak from Asuncion in 1996 were also characterized. The antigenic profile of the samples, AgV2, was compatible with one of the variants maintained by dogs in Latin America. In genetic characterization, the samples segregated in the canine (domestic and wild species)-related group in an independent subgroup that also included samples from Argentina. These results and the epidemiology of the case indicate that even with the control of rabies in domestic animals, the virus can still circulate in wildlife and may be transmitted to domestic animals and humans, demonstrating the importance of continuous and improved surveillance and control of rabies, including in wild species, to prevent outbreaks in controlled areas. © 2017 Blackwell Verlag GmbH.

Full Text Available La identificación de stocks pesqueros es un requisito básico para el manejo y la gestión de la pesca. El objetivo de este trabajo fue describir por primera vez los otolitos de la corvina de Río P. ternetzi y evaluar la existencia de diferentes stocks pesqueros entre dos áreas de la Cuenca del Plata, cuenca baja del Río Paraguay y el Río Paraná medio. Con este fin, cinco índices morfométricos aplicados sobre los otolitos sagittae (rectangularidad, circularidad AO/LO, SS/SO y PS/PO fueron comparados entre los sitios de estudio. Los otolitos sagittae son semicirculares y presentan bordes lisos. El sulcus acusticus es de tipo heterosulcoide y curvo, con abertura pseudoostio-caudal. Se observaron diferencias significativas para circularidad, rectangularidad, SS/SO y PS/PO (t- test, P 69%. Los resultados obtenidos sugieren que las poblaciones de esta especie de los ríos Paraguay y Paraná estarían parcialmente separadas, aunque mantendrían flujo de individuos entre las mismas.

To estimate the rate of drug resistance among pulmonary tuberculosis (PTB) cases in the state of Mato Grosso do Sul, Brazil, and specifically in the border areas with Paraguay and Bolivia, as well as to identify associated risk factors. The present cross-sectional, epidemiological study focused on PTB cases recorded between January 2007 and December 2010 in the State Reportable Disease Information System with results of susceptibility tests to rifampicin, isoniazid, ethambutol, and streptomycin. Dependent variables were development of resistance to a single drug or any combination of drugs. Independent variables were being a new or treated case, living in border areas, presence/absence of diabetes, and history of alcoholism. There were 789 TBP cases with susceptibility testing. The following characteristics were associated with resistance: treated case (P = 0.0001), border region (P = 0.0142), alcoholism (P = 0.0451), and diabetes (P = 0.0708). The rates of combined, primary, and acquired resistance for the state were 16.3%, 10.6%, and 39.0%, vs. 22.3%, 19.2%, and 37.5% for the border region. The rates of combined, primary, and acquired multidrug resistance for the state were 1.8%, 0.6%, and 6.3%, vs. 3.1%, 1.2%, and 12.5% for the border region. In the border region, the state should investigate drug resistance in all patients with respiratory symptoms, determine the pattern of resistance in confirmed cases, adopt directly observed treatment for cases of PTB, and develop health actions together with neighboring countries. Across the state, the levels of acquired resistance should be monitored, with investigation of resistance in all treated cases and implementation of directly observed treatment especially among patients with diabetes or alcoholism.

La introducción de la escala de inteligencia de Stanford-Binet en el Paraguay

Full Text Available RESUMEN: Aunque las primeras estrategias para evaluar la habilidad intelectual encuentran antecedentes milenarios en la antigua China, los intentos de medición en el periodo moderno comienzan con el psicólogo inglés Francis Galton en la década de 1880, mediante la aplicación de medidas fisiológicas para estimar el talento humano. A comienzos del siglo XX, los psicólogos franceses Alfred Binet y Théodore Simon construyeron las primeras escalas métricas para estimar la inteligencia de los niños. Estas fueron modificadas posteriormente en los Estados Unidos por Lewis Terman, quien publicó la revisión más conocida e influyente. En América Latina y otras regiones las adaptaciones locales se dieron en la misma época. En Paraguay, el test Stanford-Binet fue introducido en el decenio de 1920 por el maestro Ramón Indalecio Cardozo. Este no se limitó a una reproducción acrítica, sino que realizó algunas modificaciones para adaptarlo a las condiciones locales y mejorar la confiabilidad cultural de las pruebas. Este artículo estudia la introducción del test Stanford-Binet al contexto general de la educación paraguaya y los ajustes que llevó a cabo Cardozo. Para conseguirlo, se procede a una revisión de fuentes primarias y secundarias, colocando las ideas y los conceptos en el debido contexto histórico. También contribuye a ampliar otros trabajos anteriores centrados en la obra de este autor y en la psicología durante el periodo pre-universitario paraguayo.

The objective of this study was to evaluate fractions of metals (labile and pseudo-total) extracted from sediment samples collected in Itaipu Lake (boundary between Brazil and Paraguay) and to assess the dynamics and mobility of these fractions by identifying the same bioavailability and ecological risk to metals in the aquatic environment. The concentrations of metal ions were determined by flame atomic absorption spectrometry. There was a correlation between the metal ions, both in the labile and the pseudo-total, with regard to particle size. To assess metals concentrations in sediment, numerical sediment-quality guidelines were applied. The concentrations of aluminum, cadmium, iron, manganese, lead, and zinc in all sediment samples are lower than the proposed probable effects level (PEL), thus possibly indicating that there are no harmful effects from these metals. In contrast, concentrations of copper, chromium, and nickel exceeded the PEL in some samples, thus indicating that these stations are at potential risk. The level of contamination in sediments of Itaipu Lake for all metals was evaluated using contamination factor, degree of contamination, and sum-of-metals toxic unit.

Full Text Available OBJECTIVE:A decision-analytic model was constructed to evaluate the economic impact of post-introduction pneumococcal conjugate vaccine (PCV programs in Ecuador, Honduras, and Paraguay from the societal perspective. METHODS: Hypothetical birth cohorts were followed for a 20-year period in each country. Estimates of disease burden, vaccine effectiveness, and health care costs were derived from primary and secondary data sources. Costs were expressed in 2014 US$. Sensitivity analyses were performed to assess the impact of model input uncertainties. RESULTS: Over the 20 years of vaccine program implementation, the health care costs per case ranged from US$ 764 854 to more than US$ 1 million. Vaccination prevented more than 50% of pneumococcal cases and deaths per country. At a cost of US$ 16 per dose, the cost per disability-adjusted life year (DALY averted for the 10-valent PCV (PCV10 and the 13-valet PCV (PCV13 ranged from US$ 796 (Honduras to US$ 1 340 (Ecuador and from US$ 691 (Honduras to US$ 1 166 (Ecuador respectively.

Kubota Aki

2005-01-01

Full Text Available A no-tillage soybean-wheat cropping system has been practiced for many years on the "Terra Rossa" soils of eastern Paraguay. Soil compactness and soil erosion have recently been identified as potential problems. This study examines the effect of replacing unprofitable wheat by green-manure turnip (Raphanus sativus L. var. oleiferus Metzg. on soil properties and soybean production. Gaseous phase, porosity, bulk density, water saturation, cone index, pH, exchangeable-cations, available-phosphorus (P and aggregate size distribution of the soil were measured. Contrary to initial expectations, turnip did not reduce soil compactness. Instead, turnip stabilized the aggregate structure of the surface soil. Positive effects of turnip on subsequent soybean growth and yield were detected in a rather dry year but not in an exceptionally wet year. In a second part of this study, nutrient return from turnip and wheat residues were compared. Turnip produced 10.7 t ha-1 of shoot dry matter, and absorbed 294, 27, 302, 175, and 33 kg ha-1 of N, P, K, Ca, and Mg, respectively. Wheat absorbed 98, 11, 67, 11, and 7 kg ha-1 of N, P, K, Ca, and Mg, respectively. About 75% of the N absorbed by wheat was removed from the field at harvest whereas most nutrients in the turnip residue were returned to the soil before planting of soybeans with positive effects on soil fertility. Additional benefits of green-manure turnip would include a reduced chance for erosion through improvements in aggregate structure and through a more complete soil cover.

The genus Zungaro contains some of the largest catfish in South America. Two valid species are currently recognized: Zungaro jahu, inhabiting the Paraná and Paraguay basins, and Zungaro zungaro, occurring in the Amazonas and Orinoco basins. Analysing Zungaro specimens from the Amazonas, Orinoco, Paraguay and Paraná basins, based on the sequencing of COI and D-loop, we found at least three MOTUs, indicating the existence of hidden diversity within this fish group. Considering the ecological and economic values of this fish, our results are surely welcomed for its conservation, disclosing new findings on its diversity and pointing out the necessity for a detailed taxonomic revision.

The current study assessed the heritability of personality in a traditional natural-fertility population, the Ache of eastern Paraguay. Self-reports (n = 110) and other-reports (n = 66) on the commonly used Big Five Personality Inventory (i.e., extraversion, agreeableness, conscientiousness, neuroticism, openness) were collected. Self-reports did not support the Five Factor Model developed with Western samples, and did not correlate with other-reports for three of the five measured personality factors. Heritability was assessed using factors that were consistent across self- and other-reports and factors assessed using other-reports that showed reliabilities similar to those found in Western samples. Analyses of these items in combination with a multi-generation pedigree (n = 2,132) revealed heritability estimates similar to those found in most Western samples, although we were not able to separately estimate the influence of the common environment on these traits. We also assessed relations between personality and reproductive success (RS), allowing for a test of several mechanisms that might be maintaining heritable variation in personality. Phenotypic analyses, based largely on other-reports, revealed that extraverted men had higher RS than other men, but no other dimensions of personality predicted RS in either sex. Mothers with more agreeable children had more children, and parents mated assortatively on personality. Of the evolutionary processes proposed to maintain variation in personality, assortative mating, selective neutrality, and temporal variation in selection pressures received the most support. However, the current study does not rule out other processes affecting the evolution and maintenance of individual differences in human personality. PMID:23527163

Full Text Available This article intends to evince and analyze the impact of the Christian conceptions of sickness and death on the Guarani indian sensibility and its translation in terms of representations and social practices in the Jesuitical reductions. The analysis of the records made by the missionaries, especially the Cartas Ânuas of the Jesuitical Province of Paraguay regarding the period from 1609 to 1675, revealed that, on the one hand, the Guarani kept traditional practices of their religious sensibility – as is evinced in the resignification of the "copious crying" and the funereal laments –, and, on the other hand, that the missionaries, besides incorporating the native pharmacopoeia and many of the indian healing practices, skillfully manipulated the cures and the "bien morir", a strategy that was fundamental to the success of the civilization-conversion project of the Companhia de Jesus alongside the Guarani.

The Hydrologic Regime of the La Plata Basin in South America

2002-12-01

The main components of the hydrologic cycle of the La Plata basin in southeastern South America are investigated using a combination of observations, satellite products and National Centers for Environmental Prediction-National Center for Atmospheric Research (NCEP-NCAR) global reanalyses. La Plata basin is second only to the Amazon basin in South America, and plays a critical role in the economies of the region. It is a primary factor in energy production, water resources, transportation, agriculture and livestock. Of particular interest was to evaluate the annual cycle of the hydrologic cycle components. The La Plata annual-mean river discharge is about 21,000 m3 s-1, and the amplitude of the mean annual cycle of La Plata River discharge is small: it is slightly larger during late summer, but continues with large volumes even during winter. The reason is that different precipitation regimes over different locations contribute to the total river discharge. One regime is found toward the northern boundary, where precipitation peaks during summer in association with the southernmost extension of the monsoon system. A second one is found over the central part of the basin, where precipitation peaks at different times in the seasonal cycle. Further analysis of the main tributaries of La Plata (Paran , Uruguay and Paraguay) reveals that each has a well defined annual cycle, but with different phases that can be traced primarily to each basin's physiography and precipitation regime. The upper and middle portions of the Paran River are most influenced by the summer monsoon regime, thus the river has a maximum discharge in late summer. The annual cycle of precipitation over the Uruguay River basin has two maxima, one in late autumn and the second one in spring and, consistently, the river discharge is largest in winter and spring. The smooth annual cycle of the Paraguay River discharge, with a maximum in winter, is the result of the Pantanal, a large wetland that

It dispersed north through Paraná, Uruguay and Paraguay Rivers. The study evaluated the macroscale (18° to 34° S; 45° to 60° W distribution of L. fortunei (larval stages in the main rivers and reservoirs of La Plata Basin. Samplings were performed through 68 µm vertical plankton net hauls. Limnological variables were simultaneously determined. Larvae abundance correlated significantly with oxygen (positively in summer, with temperature (positively in winter and with total phosphorus and total nitrogen (both negatively in winter.

2015-12-01

The capybara, Hydrochoerus hydrochaeris, is an herbivorous rodent widely distributed throughout most of South American wetlands that lives closely associated with aquatic environments. In this work, we studied the genetic structure of the capybara throughout part of its geographic range in Argentina using a DNA fragment of the mitochondrial control region. Haplotypes obtained were compared with those available for populations from Paraguay and Venezuela. We found 22 haplotypes in 303 individuals. Hierarchical AMOVAs were performed to evaluate the role of river drainages in shaping the genetic structure of capybara populations at the regional and basin scales. In addition, two landscape genetic models, isolation by distance and isolation by resistance, were used to test whether genetic distance was associated with Euclidean distance (i.e. isolation by distance) or river corridor distance (i.e. isolation by resistance) at the basin scale. At the regional scale, the results of the AMOVA grouping populations by mayor river basins showed significant differences between them. At the basin scale, we also found significant differences between sub-basins in Paraguay, together with a significant correlation between genetic and river corridor distance. For Argentina and Venezuela, results were not significant. These results suggest that in Paraguay, the current genetic structure of capybaras is associated with the lack of dispersion corridors through permanent rivers. In contrast, limited structuring in Argentina and Venezuela is likely the result of periodic flooding facilitating dispersion.

The La Plata River Basin is one of the largest international river basins in the world, with an area of about 3 million km2. It spreads across five countries (Argentina, Bolivia, Brazil, Paraguay and Uruguay), and its water resources are essential for their economic development. Together with reservoir development, extensive deforestation, intensive agriculture practices and large urban developments took place in the Paraná, Paraguay and Uruguay basins, affecting environmental conditions and raising important issues concerning water resources use and conservation. Therefore, the need to promote participatory and cooperative efforts among water resources stakeholders, as well as the systematic exchange of information and experiences on common regional problems among organizations and experts from throughout the basin who are devoted to water resources use and management, was reported by researchers and managers gathered at the First and Second International Workshops on Regional Approaches for Reservoir Development and Management in the La Plata River Basin (held in 1991 and 1994). As a concrete response to this need, the efforts of a number of organizations from various countries within the basin, with the support of international and national governmental organizations, resulted in the foundation of La Plata River Basin Environmental Research and Management Network (RIGA) in March 2001. This was within the framework of the Third International Workshop, which was precisely one of the short-term activities included in the RIGA Action Plan. During the preparatory processes for the RIGA Network, the presence of Japanese cooperation supporting the La Plata River Basin Workshops through a non-governmental international organization (ILEC) played an important role in stimulating such an organization-based joint approach in the basin. This outcome, although not originally planned, constituted a welcomed byproduct of its main specific interest in the region, which was the

20 medicinal plants of Paraguay and 3 medicinal plants of Thailand were examined on nerve growth factor (NGF)-potentiating activities in PC12D cells. The trail results demonstrated that the methanol extracts of four plants, Verbena littoralis, Scoparia dulcis, Artemisia absinthium and Garcinia xanthochymus, markedly enhanced the neurite outgrowth induced by NGF from PC12D cells. Furthermore, utilizing the bioactivity-guided separation we successfully isolated 32, 4 and 5 constituents from V. littoralis, S. dulcis and G. xanthochymus, respectively, including nine iridoid and iridoid glucosides (1-9), two dihydrochalcone dimers (10 and 11), two flavonoids and three flavonoid glycosides (12-16), two sterols (17 and 18), ten triterpenoids (19-28), five xanthones (29-33), one naphthoquinone (34), one benzenepropanamide (35), four phenylethanoid glycosides (36-39) and two other compounds (40 and 41). Among which, 15 compounds (1-4, 10-11, 14-18, 29-31 and 34) were new natural products.

Full Text Available Según informes anecdóticos, la provisión de servicios de planificación familiar y salud reproductiva en América Latina se ve gravemente obstaculizada por el hecho de que los proveedores de dichos servicios hacen caso omiso de las pautas establecidas para los servicios de planificación familiar. En este estudio, que se llevó a cabo en Paraguay entre 1998 y 2000, se evaluó en qué medida los proveedores de servicios observaban las pautas revisadas y posteriormente publicadas y diseminadas. Los investigadores encontraron indicios de que las nuevas pautas no se observaban en el contexto de la atención continuada de mujeres que usaban dispositivos intrauterinos (DIU o anticonceptivos orales. Contrario a lo que dichas pautas recomiendan, los proveedores de servicios imponían condiciones, haciendo, por ejemplo, que las usuarias de DIU regresaran a la clínica hasta cinco veces durante el primer año después de la colocación del dispositivo. Las usuarias de anticonceptivos orales también enfrentaron obstáculos, entre ellos el de verse limitadas a no más de dos ciclos de pastillas cada vez, aunque las usaran con regularidad. Según estos resultados, las exigencias que rodean a la provisión y al seguimiento no fomentan, sino que desalientan el uso continuado de DIU y de anticonceptivos orales y podrían llevar a la suspensión de estos métodos por temor a que el DIU no sea seguro y estable o por la incomodidad de tener que volver a la clínica varias veces a recoger las pastillas. Los ministerios de salud en América Latina deben redoblar sus esfuerzos por educar a los proveedores de servicios de planificación familiar en cuanto al contenido y la razón fundamental de las recomendaciones vinculadas con las pautas nacionales. Asimismo, siempre que se disponga de los resultados de investigaciones, estos se deben presentar a los proveedores de servicios para reforzar ante ellos la credibilidad de las recomendaciones y demostrarles que las

Thyroid disease is frequent in Paraguay, a country with a prevalence of goiter 48,6% in general population located in the center of South America. Grave's disease constitutes the most common thyroid hyper function observed whose treatment can be carried out with medication (propilthiouracil, metamizole, etc.), surgery or iodine 131( 131 I). We analyzed 70 patients this type of hyperthyroidism treated with the 131 I, in its clinical aspect pre and post treatment, ultrasound and nuclear scan findings of the gland thyroid, the hormonal respond F4, T3, TSH, thyroid antibodies TPOab, TGab, TRab. Besides the diffuse classic image observed in the thyroid scan and by ultrasonography of the gland, in Grave's disease, 4 types of images were identified with nodules (multi nodular, hot nodule, cold nodule and miliar). The group with diffuse increase in size form was the most numerous (50%) continued by the variety multi nodular (30%), Marin-Lenhart's Sx (hot nodule) 14%, miliar 3%, and cold nodule 3%.

Full Text Available La anemia es un problema de salud pública a nivel mundial. En Paraguay, existen datos limitados sobre la frecuencia de anemia en mujeres en edad reproductiva no gestantes. Este estudio piloto descriptivo de corte transverso tuvo como objetivo determinar la frecuencia de anemia y deficiencia de hierro, el estado nutricional, hábitos alimentarios y tóxicos en 99 mujeres no gestantes en edad reproductiva de 18 a 48 años que acudieron al Hospital Regional de Villa Hayes en Octubre del 2.014. La anemia se determinó tomando como punto de corte una concentración de hemoglobina <12 g/dL. La deficiencia de hierro se evaluó según la saturación de la transferrina. Además, se evaluó el índice de masa corporal (IMC y los hábitos nutricionales a través de una encuesta. La frecuencia de anemia fue de 15,1% (IC95% 8,7-23,8%, de éste el 33,3% (IC95% 12,8-61,6% correspondió a anemia ferropénica. Se observó asociación entre la presencia de anemia y los niveles disminuidos tanto del hematocrito (<38% como del número de glóbulos rojos (<4,2x 106/uL. Todas las mujeres con anemia ferropénica tenían peso <64 kg e IMC <24,5 kg/m2. Además, se detectó una alta frecuencia de sobrepeso y obesidad (45,4%, alto consumo de grasas, y bajo consumo de legumbres, frutas y verduras. A partir de estos resultados, se sugiere mantener la vigilancia e implementar programas que incluyan a estas mujeres, tanto para evitar deficiencias nutricionales como excesos.

Full Text Available We identified and analysed droughts in the La Plata Basin (divided into seven sub-basins for the current period (1961–2005 and estimated their expected evolution under future climate projections for the periods 2011–2040, 2041–2070, and 2071–2099. Future climate projections were analysed from results of the Eta Regional Climate Model (grid resolution of approximately 10 km forced by the global climate model HadGEM2-ES over the La Plata basin, and considering a RCP4.5 emission scenario. Within each sub-basin, we particularly focused our drought analyses on croplands and grasslands, due to their economic relevance. The three-month Standardized Precipitation Evapotranspiration Index (SPEI3 was used for drought identification and characterization. Droughts were evaluated in terms of time (percentage of time from the total length of each climate scenario, space (percentage of total area, and severity (SPEI3 values of cells characterized by cropland and grassland for each sub-basin and climate scenario. Drought-severity–area–frequency curves were developed to quantitatively relate the frequency distribution of drought occurrence to drought severity and area. For the period 2011–2040, droughts dominate the northern sub-basins, whereas alternating wet and short dry periods dominate the southern sub-basins. Wet climate spread from south to north within the La Plata Basin as more distant future scenarios were analysed, due to both a greater number of wet periods and fewer droughts. The area of each sub-basin affected by drought in all climate scenarios was highly varied temporally and spatially. The likelihood of the occurrence of droughts differed significantly between the studied cover types in the Lower Paraguay sub-basin, being higher for cropland than for grassland. Mainly in the Upper Paraguay and in the Upper Paraná basins the climate projections for all scenarios showed an increase of moderate and severe droughts over large regions

2016-03-01

Full Text Available Itararé Group represents the glacial record of Gondwana Continent in the intracratonic Paraná Basin, encompassing regions of Southern Brazil, Eastern Paraguay, Northeast Argentina and Northern Paraguay. Itararé Group is the thickest sedimentary package of Paraná Basin, and was deposited over 36 million years during the end of the Carboniferous and the beginning of the Permian. However, in relation to its paleoenvironmental evolution, it is generally understood that more research is necessary, in order to better understand the genesis of the Itararé Group in different places. The present work entailed mapping facies associations for the Itararé Group in the city of Salto, in São Paulo State, by identifying and classifying sedimentary facies that, in turn, were utilized to develop a paleoenvironmental evolution model. This model was based on geological mapping carried out over 125 km². Petrological and petrographic descriptions of 32 outcrops of Itararé Group also were studied. These results were compared with subsurface data obtained by Sistema de Informações de Águas Subterrâneas, Serviços Geológicos do Brasil (SIAGAS-CPRM; System Water Information Groundwater, Geological Survey of Brazil. Through lithofacies and petrographic analyses and making a comparison between five column sections, surface and subsurface data, a stratigraphic correlation model was established for the region. Through this model was possible to identify four facies associations, which, together, indicate how the paleoenvironmental evolution of the region occurred. The first three associations (A, B, C were interpreted as being formed in subaqueous environment, being related to sandy lobe systems, followed by the last association (D, pertaining to a fluvial system.

Full Text Available OBJETIVO: Las enfermedades cardiovasculares son la principal causa de mortalidad en el mundo. Aunque la mayoría son prevenibles, su prevalencia sigue aumentando. El objetivo de este estudio fue estimar la prevalencia de factores de riesgo cardiovascular en una población hospitalaria ambulatoria urbana y adulta de Asunción, Paraguay. MÉTODOS: Se realizó un análisis transversal de todos los pacientes incluidos en el estudio prospectivo de prevención cardiovascular AsuRiesgo dirigido al cambio del estilo de vida a un estilo de vida saludable. Se invitó a participar a personas de 18 y más años de edad que se encontraban en las zonas de espera de consultorios de un hospital terciario. Se obtvuvo información anamnésica, antropométrica y de laboratorio. Resultados: Se incluyeron 18 287 pacientes de 51 ± 16 años de edad, de los cuales 67,5% fueron mujeres. La media de peso corporal fue 77,5 ± 16,2 kg y el índice de masa corporal, 29,7 ± 5,9 kg/m². Las prevalencias de antecedentes de infarto de miocardio, accidente vascular cerebral, diabetes mellitus e hipertensión fueron, respectivamente, 2,6, 3, 13,3 y 53%, y las del hábito de fumar, dieta no saludable, sedentarismo y estrés psicológico, 29,3, 41,2, 58,2 y 56,6%. Por último, la prevalencia global de obesidad y sobrepeso fue 79,6%, las de prehipertensión e hipertensión arterial sistémica, 39 y 25%, respectivamente, y la del síndrome metabólico, 34,7%. CONCLUSIONES: Si bien las prevalencias del hábito de fumar, hipertensión arterial sistémica y diabetes mellitus fueron bajas, las de obesidad, sedentarismo, estrés psicológico, dieta no saludable y síndrome metabólico fueron muy elevadas, lo cual justifica una acción global para prevenir discapacidades o fallecimientos por enfermedad isquémica cardiaca o cerebral.

Full Text Available La incorporación de las plantas medicinales en la Atención Primaria de Salud (APS, constituye un gran desafío. Según la OMS, el uso de las plantas medicinales constituye una terapia más natural, más inocua, efectiva, de un costo racional y asequible a las poblaciones. Para establecer el uso seguro y eficaz es necesaria la correcta identificación taxonómica de las especies y el origen de las mismas. El objetivo del estudio fue identificar taxonómicamente las plantas medicinales utilizadas por pacientes que consultaron en los servicios de Unidad de Salud Familiar (USF de la IV Región Sanitaria del Guairá, Paraguay, de agosto a diciembre de 2.011, además del hábitat de procedencia de las mismas. Los pacientes fueron encuestados sobre las plantas medicinales utilizadas y el modo de empleo de las mismas. Las encuestas fueron acompañadas por muestras de las plantas medicinales utilizadas que posteriormente fueron identificadas taxonómicamente. Se identificaron 56 especies utilizadas para diversos fines medicinales, de las cuales las más mencionadas fueron menta’i (Mentha x piperita, ñangapiry (Eugenia uniflora, salviarã (Lippia alba, koku (Allophylus edulis, typycha curaty (Scoparia dulcis y ka’are (Chenopodium ambrosioides.

Full Text Available The oviposition preference of the red mite Oligonychus yothersi McGregor was evaluated under laboratory in 52 Paraguay tea progenies and one control collected in a local farm. The experiments were conducted on Paraguay tea leaf discs infested with one adult female mite/disc, incubated in a climate chamber (25±1ºC, 14h photophase for five days. Evaluations were performed daily, by counting the number of eggs laid in the period, the number of female escapes in the first 48 hours, as well as the number of eggs laid before the escaping. It was verified that discrimination by the mite occurred on two groups of progenies, in relation to the number of eggs: one group was different from the control (53.8% of the progenies and the other was identical to it (46.2% of the progenies. In the first group, 60.7% of progenies were less oviposited while a higher number of eggs/female than the control was verified in 39.3% of them. In 57.7% of progenies there was escape of some mites (10 to 40%, and in 10 of these progenies no eggs were laid. The data provide evidences that in some of the progenies evaluated there is resistance by non-preference to oviposition of the Paraguay tea red mite.A preferência para oviposição do ácaro-vermelho, Oligonychus yothersi McGregor, foi avaliada em condições de laboratório em 52 progênies de erva-mate e uma testemunha coletada em uma propriedade da região.

A Darwinian mystery: fluctuations in runoff from the la Plata basin (Alexander von Humboldt Medal Lecture)

Science.gov (United States)

Clarke, R. T.

2012-04-01

During the voyage of HMS Beagle, Charles Darwin sailed in a small boat along the River Paraná, a major tributary of the la Plata drainage system. He wrote about the occurrence of severe droughts (the latest of which had been termed the "gran seco") alternating with periods of severe flooding. From reports received, he concluded that these events appeared to be cyclic with a period "of about fifteen years". Because extended periods of low flow in Brazilian rivers are of immense economic importance, the presentation describes a search for the material which led Darwin to this conclusion. A prolonged period of low flow in another la Plata tributary - the River Paraguay - not unlike the "gran seco" reported by Darwin, has occurred more recently; if such low flows were to recur in the future, the consequences would be severe for a region where more than 70% of energy is supplied by hydropower. A priori considerations suggest the use of statistical long-memory models for predicting River Paraguay water-levels, and some preliminary results from their use are presented.

The fluoride in the groundwater of Guarani Aquifer System: the origin associated with black shales of Paraná Basin

Science.gov (United States)

Kern, M. L.; Vieiro, A. P.; Machado, G.

2008-09-01

This work presents petrological and geochemical results of the black shales interval from Permian and Devonian strata of the Paraná Basin, Brazil and its relationships with fluoride of groundwater from Guarani Aquifer System. The Guarani Aquifer, located in South Brazil, Uruguay, Paraguay and Argentine, presents contents of fluoride higher than the Brazilian accepted potability limits. Several hypotheses have been presented for the origin of the fluoride in the groundwater of the Guarani Aquifer. Microcrystalline fluorite was registered in black shales of Ponta Grossa and Irati formations from Paraná Basin. The results shown in this work suggest that fluoride present in groundwater of Guarani Aquifer can be originated in deeper groundwater that circulates in Ponta Grossa and Irati formations. The interaction of the groundwater coming from deeper black shales with the groundwater-bearing Aquifer Guarani System occurs through regional fragile structures (faults and fractures) that constitute excellent hydraulic connectors between the two sedimentary packages. The microcrystalline fluorite registered in Ponta Grossa and Irati Formations can be dissolved promoting fluoride enrichment in groundwater of these black shales and Guarani Aquifer System.

Full Text Available Abstract: Terror and violence during the Paraguayan War:  ‘La masacre de 1869’ and the families of ConcepciónThis paper addresses the massacre that took place  in the District of Concepción between April and  May 1869, one of many ordered by Marshal Francisco S. López during the last months of the Paraguayan War. The object here is to interpret the  killings and other extreme measures carried out in  the context of a conflict without mercy. Such  measures interrupted the state of law and opened  the way for arbitrary and unjust acts and the demonstration of the abusive power of a leader who  exercised unscrupulous violence. The explanations, in one way or another, would seem to conclude that his behaviour was irrational. However,  the paper aims to understand the different forms  of rationality that produced the outbreaks of violence. It intends to reveal a fiercer and more complex history from the treatment, on a local scale,  of a universal issue: ‘the violence of war’.Resumen:El artículo aborda la masacre llevada a cabo en el Departamento de Concepción entre los meses de  abril y mayo de 1869, una de las tantas que ordenó el Mariscal Francisco S.

La Plata Basin is shared by five countries (Argentina, Bolivia, Brazil, Paraguay and Uruguay), which have fast growing economies in South America. These countries need energy for their sustainable development; hence, hydropower can play a very important role as a renewable clean source of energy. This paper presents an analysis of the current hydropower production and electricity demand in La Plata Basin (LPB), and it analyses the maximum and residual hydropower potential of the basin for a horizon of 30 yr (i.e. year 2040). Current hydropower production is estimated based on historical available data, while future energy production is deduced from the available water in the catchment (estimated based on measured hydrographs of the past years), whereas electricity demand is assessed by correlating existing electricity demand with the estimated population growth and economic development. The maximum and residual hydropower potential of the basin were assessed for the mean annual flows of the present hydrological regime (1970-2000) and topographical characteristics of the area. Computations were performed using an integrated GIS environment called VAPIDRO-ASTE released by the Research on Energy System (Italy). The residual hydropower potential of the basin is computed considering first that the water supply needs for population, industry and agriculture are served, and then hydropower energy is produced. The calculated hydropower production is found to be approximately half of the estimated electricity demand, which shows that there is a need to look for other sources of energy in the future.

Genetic evidence of population structuring in the neotropical freshwater fish Brycon hilarii (Valenciennes, 1850

Directory of Open Access Journals (Sweden)

A Sanches

Full Text Available Brycon hilarii is a migratory fish widely distributed throughout the Paraguay River Basin. It is appreciated in sport fishing and for its superior meat quality. It is also the main species for tourist attraction in the Bonito region (State of Mato Grosso do Sul, Brazil. Considering the lack of information on the genetic structure of the fish of this species, the aim of the present study was to detect the genetic variability of Brycon hilarii through RAPD markers. A total of eighty specimens collected in different seasons at four sites of the Miranda River sub-basin (Paraguay River Basin, Brazil were used for analysis. The results of genetic similarity, Shannon diversity, and AMOVA revealed differences between the sampling sites. Through AMOVA, differences between populations were more evident among the animals collected during the non-reproductive season, corresponding to a time of less movement of these fish. A population structuring model in which B. hilarii appears organized into genetically differentiated reproductive units that coexist and co-migrate through the studied system was suggested, contrasting the currently accepted idea that freshwater migratory fish form large panmictic populations in a determined hydrographic system. Despite the lack of a complete picture regarding the distribution of B. hilarii in the studied region, this initial idea on its population genetic structure could be an important contribution to providing aid for management and conservation programs of these fish.

Current hydropower production is estimated based on historical available data, while future energy production is deduced from the available water in the catchment (estimated based on measured hydrographs of the past years, whereas electricity demand is assessed by correlating existing electricity demand with the estimated population growth and economic development. The maximum and residual hydropower potential of the basin were assessed for the mean annual flows of the present hydrological regime (1970–2000 and topographical characteristics of the area.

Computations were performed using an integrated GIS environment called VAPIDRO-ASTE released by the Research on Energy System (Italy. The residual hydropower potential of the basin is computed considering first that the water supply needs for population, industry and agriculture are served, and then hydropower energy is produced. The calculated hydropower production is found to be approximately half of the estimated electricity demand, which shows that there is a need to look for other sources of energy in the future.

A successful case of biological invasion: the fish Cichla piquiti, an Amazonian species introduced into the Pantanal, Brazil

Directory of Open Access Journals (Sweden)

EK. Resende

Full Text Available The "tucunaré", Cichla piquiti, an exotic Amazonian fish has become established along the left bank of the Paraguay River in the Pantanal. It was introduced by escaping from culture ponds in the Upper Piquiri River and spread downstream, along the lateral flooded areas of that river, continuing through the clear waters of the left bank of the Paraguay River and reaching south as far as the Paraguai Mirim and Negrinho rivers. Adult spawners have been found in the region, meaning that it is a self-sustained population. Reproduction occurs in the period of low waters. They were found feeding on fishes of lentic environments belonging to the families Characidae, Cichlidae and Loricariidae. Until the end of 2004, its distribution was restricted to the left bank of the Paraguay River, but in March 2005, some specimens were found on the right bank, raising a question for the future: what will be the distribution area of the tucunaré in the Pantanal? Information about its dispersion is increasing: it is known to be in the Tuiuiú Lake, Pantanal National Park and in the Bolivian Pantanal, all of them on the right bank of the Paraguay River. The hypothesis that the "tucunaré" could not cross turbid waters, such as in the Paraguay River, was refuted by these recent findings. Possibly, the tucunaré's capacity to lay more than one batch of eggs in a reproductive period, as well as its care of eggs and young, lead them to establish themselves successfully in new environments, as has been observed in the Pantanal and other localities.

Full Text Available The number of buffaloes in the American continent is growing at the explosive rate of 12.7 % a year, well above all other continents. Within this context the different situations of the southern part of South America are described, those countries that two hundred years ago were part of the River Plate Viceroyship and the Chile General Command, both of them part of the Spanish empire. The first steps of buffaloes in Paraguay, Bolivia and Uruguay. The expansion of buffaloes in Argentina and their recent start up in Chile. The production systems in the region are described, principally Argentina and Paraguay. The major changes and expansion of agriculture in Argentina are displacing cattle production from the North towards the Tropics, where buffalo has proven to be very superior in productivity compared to cattle production thanks to its very good adaptation to the local conditions. In Paraguay, a totally subtropical country, something very similar is happening. Paraguay has consolidated its sales of buffalo hides and beef. Argentina is well on its way to having a very efficient buffalo beef marketing competing with cattle of the highest quality. Buffalo milk production is still not mature in these countries, although there are several projects underway in Uruguay, Bolivia and Argentina.

Banded Knifefishes (Gymnotus, Gymnotidae) comprise the most species-rich genus of Neotropical electric fishes, with 41 species currently described from throughout the humid Neotropics, from Mexico to Argentina. Despite substantial alpha-taxonomic work in recent years, the diversity of Gymnotus in some regions remains poorly understood. Here we describe the Gymnotus fauna of the Upper Madeira basin of Bolivia and Peru from examination of more than 240 adult specimens. Species are delimited and described using body proportions (traditional morphometrics), fin-ray, squamation and laterosensory-pore counts (meristics), quantitative shape differences (geometric morphometrics), osteological traits, and color patterns. Comparisons of standardized linear measures as well as multivariate statistical methods validate the presence in the Upper Madeira basin of three previously described species, two with wide-spread geographic distributions throughout Greater Amazonia (G. carapo and G. coropinae), and one (G. chaviro) endemic to southwestern Amazonia. We also diagnose and describe two new species that are endemic to the Upper Madeira basin: G. eyra n. sp., morphologically most similar to G. mamiraua from lowland Amazonia, and G. riberalta n. sp., morphologically most similar to G. pantanal from the Paraguay-Paraná basin. The five Gymnotus species from the Upper Madeira basin are not monophyletic, each species being more closely related to a different species from another region; i.e. the Gymnotus species from the Upper Madeira represents a polyphyletic assemblage. These descriptions to 43 the number of valid Gymnotus species.

The investigated area involves the Pipeline Row of Bolivia Mato-Grosso, inserted in the South-center of The Serrana Province (Almeida, 1964). The south-center section of Serrana Province is a water divisor from those that leaks west directly to Paraguay River from the waters that leaks on the east side to Pantanal. This work has as main subject, to diagnose and to value the environmental impacts that occurred and can occur in the future on the brooks and springs where there were Pipeline Bolivia Mato-Grosso interference on its crossing at the Serrana area, in Caceres municipality. The springs monitor were done during 18 months (march, 2001 to September, 2001), during and after the ending of the works, including different climates and hydrologic conditions, making it possible to diagnose and to value the draining behavior on the drought and on the overflow epoch. So, we believe that the knowledge about the interferences, risks and alterations that reflects on the fluvial duct of the sub-basin that drains the Serrana Province and leaks to Paraguay River may be contributing indirectly or directly to the Pantanal conservation.

This article is the first in a series of international case studies developed by the American Cancer Society to illustrate use of publicly available surveillance data for regional tobacco control. A descriptive analysis of Brazil and Paraguay cigarette production and trade data from official sources. Per capita cigarette consumption for Brazil and its neighbour was calculated from 1970 to 1998 using data on production, imports, and exports from NATIONS, the National Tobacco Information Online System. A 63% decrease was observed in the estimate of per capita consumption of cigarettes in Brazil between 1986 and 1998 (from 1913 cigarettes per person in 1986 to 714 cigarettes per person in 1998) and a 16-fold increase in Paraguay was observed during the same period (from 678 cigarettes per person in 1986 to 10 929 cigarettes per person in 1998). Following Brazil's 1999 passage of a 150% cigarette export tax, cigarette exports fell 89% and Brazil's estimated per capita consumption rose to 1990 levels (based on preliminary data). Per capita consumption in Paraguay also fell to 1990 levels. These trends coincide with local evidence that large volumes of cigarettes manufactured in Brazil for export to Paraguay are smuggled back and consumed as tax-free contraband in Brazil. It is hoped that this case study will draw wider public attention to the problems that smuggling presents for tobacco control, help identify other countries confronting similar issues, and stimulate effective interventions.

TBG - Transportadora Gasoduto Bolivia-Brasil S.A, executes routine maintenance works at the Gas Pipeline Right of Way, seeking its integrity. In the wetlands of Pantanal, near the Paraguay river crossing, the organic-alluvial soil was submitted to the process of subsidence. This process, associated with the river water flow erosion, shrank the soil volume and diminished or extinguished the pipeline land cover. The pipeline was exposed to the environment, and submitted to tension stresses and the risk of low cycle fatigue during the floods. The cathodic protection system also had to be evaluated, specially in the drought. To mitigate the problem, the embankment technique was adopted using sandy soil, reinforced with polyester geo-webs and with woven polipropene geo-textiles. The solution also used geo-webs with soil-cement as protection elements against the degradation of the geo-textiles blankets. Some monitoring works are associated with those interventions: monitoring of cathodic protection; topographical verification of horizontal and vertical displacements of the pipeline; levels of land covering, and rainfalls and flood measurement. The base of the embankment was built with hydraulic transported soil, and at the end consistently supported the gas pipeline. (author)

Diversity and chromosomal evolution in the genus Ancistrus Kner, 1854 (Loricariidae: Ancistrini from three hydrographic basins of Mato Grosso State, Brazil

Directory of Open Access Journals (Sweden)

Sandra Mariotto

Full Text Available Cytogenetic analyses were carried out in 117 specimens of seven species of the genus Ancistrus from three hydrographic in Mato Grosso State: Paraguay, Araguaia-Tocantins and Amazon basins. Conventional cytogenetic techniques were used to obtain mitotic chromosomes. C-banding was performed to detect heterochromatic regions and silver nitrate staining was used to identify nucleolar organizer regions (Ag-NORs. The counted and paired chromosomes revealed diploid numbers ranging from 2n = 40 to 2n = 54 with karyotype formulae varying from FN = 80 to FN = 86. Single marks in distinct chromosomes identified the nucleolar organizer regions. The constitutive heterochromatin was scarce in the diploid number from 2n = 50 to 2n = 54 and conspicuous blocks were observed in a single species with 2n = 40 chromosomes. These data corroborate the hypotheses of reduction of diploid number in species with derived features such as presence of sex chromosomes and polymorphisms, besides allowing inferences about the evolutionary mechanisms and the ancestor karyotype that favored the diversification of this important genus in the tribe Ancistrini.

Full Text Available This article reviews the electoral accountability dimension as a constitutive mechanism of Paraguayan democracy since 1989, analyzing the factors that limit the representation contained in the administration of the Paraguayan government as a result of the electoral process. We provide an analytic contrast between the democratic principles that guide the Paraguayan electoral institutions and the way their designs are enforced, identifying the gap between formal and informal rules as determinants of political representation. We also describe the barriers that prevent effective access of the population to political participation and competition, the advantages possessed by traditional political parties and interest groups, as well as their implications for democracy. We also review the degree to which elected officials are representative of historically excluded social groups as a result, emphasizing the way women, indigenous and peasant communities have potentially limited power to exercise political influence due to limitations to participation by structural and institutional factors.

Full Text Available Anolis es uno de los géneros de lagartijas más grandes con más de 380 especies presentes en el Centro y Sur de América, lo cual dificulta muchas veces su identificación. Particularmente Anolis meridionalis fue descrito en base a un ejemplar procedente de Paraguay. Esta especie se encuentra ampliamente distribuida en Brasil, Paraguay y Bolivia. Sin embargo, debido a que la descripción original es pobre en caracteres diagnósticos y a que el holotipo se encuentra perdido, es difícil en ocasiones conocer la identidad de ejemplares de especies afines. Es por eso que en este trabajo se designa y describe un neotipo para Anolis meridionalis con la esperanza de que ayude a resolver los problemas taxonómicos de las especies más australes del género. Anolis is one of the largest genus of lizards with more than 380 species distributed in Central and South America, which often difficult their identification. Particularly Anolis meridionalis was described upon one specimen from Paraguay. This species is widely distributed in Brazil, Paraguay and Bolivia. Nevertheless, because the original description is poor in diagnostic characters and the holotype is currently lost, sometimes is difficult to know the identity of specimens of related species. For that reason in this work is designed and described a neotype for Anolis meridionalis with the hope that this helps to solve some taxonomic problems in the southernmost species of the genus.

We investigated the influence and relative importance of insecticides and other agricultural stressors in determining variability in invertebrate communities in small streams in intensive soy-production regions of Brazil and Paraguay. In Paraguay we sampled 17 sites on tributaries of the Pirapó River in the state of Itapúa and in Brazil we sampled 18 sites on tributaries of the San Francisco River in the state of Paraná. The riparian buffer zones generally contained native Atlantic forest remnants and/or introduced tree species at various stages of growth. In Brazil the stream buffer width was negatively correlated with sediment insecticide concentrations and buffer width was found to have moderate importance in mitigating effects on some sensitive taxa such as mayflies. However, in both regions insecticides had low relative importance in explaining variability in invertebrate communities, while various habitat parameters were more important. In Brazil, the percent coverage of soft depositional sediment in streams was the most important agriculture-related explanatory variable, and the overall stream-habitat score was the most important variable in Paraguay streams. Paraguay and Brazil both have laws requiring forested riparian buffers. The ample forested riparian buffer zones typical of streams in these regions are likely to have mitigated the effects of pesticides on stream invertebrate communities. This study provides evidence that riparian buffer regulations in the Atlantic Forest region are protecting stream ecosystems from pesticides and other agricultural stressors. Further studies are needed to determine the minimum buffer widths necessary to achieve optimal protection.

Nitrogen cycle and ecosystem services in the Brazilian La Plata Basin: anthropogenic influence and climate change.

Science.gov (United States)

Watanabe, M; Ortega, E; Bergier, I; Silva, J S V

2012-08-01

The increasing human demand for food, raw material and energy has radically modified both the landscape and biogeochemical cycles in many river basins in the world. The interference of human activities on the Biosphere is so significant that it has doubled the amount of reactive nitrogen due to industrial fertiliser production (Haber-Bosch), fossil fuel burning and land-use change over the last century. In this context, the Brazilian La Plata Basin contributes to the alteration of the nitrogen cycle in South America because of its huge agricultural and grazing area that meets the demands of its large urban centres - Sao Paulo, for instance - and also external markets abroad. In this paper, we estimate the current inputs and outputs of anthropogenic nitrogen (in kg N.km(-2).yr(-1)) in the basin. In the results, we observe that soybean plays a very important role in the Brazilian La Plata, since it contributes with an annual entrance of about 1.8 TgN due to biological nitrogen fixation. Moreover, our estimate indicates that the export of soybean products accounts for roughly 1.0 TgN which is greater than the annual nitrogen riverine exports from Brazilian Parana, Paraguay and Uruguay rivers together. Complimentarily, we built future scenarios representing changes in the nitrogen cycle profile considering two scenarios of climate change for 2070-2100 (based on IPCC's A2 and B2) that will affect land-use, nitrogen inputs, and loss of such nutrients in the basin. Finally, we discuss how both scenarios will affect human well-being since there is a connection between nitrogen cycle and ecosystem services that affect local and global populations, such as food and fibre production and climate regulation.

Migration and dispersal of Anthonomus grandis (Coleoptera: Curculionidae in South America Migración y dispersión de Anthonomus grandis (Coleoptera: Curculionidae en América del Sur

Directory of Open Access Journals (Sweden)

Teodoro Stadler

Full Text Available This study discusses the dispersal of Anthonomus grandis Boheman, the cotton boll weevil, in Argentina, Brazil, Paraguay and Bolivia, exploring the ecological and physiological factors that have made the dispersal and establishment of this insect in South America so successful. The boll weevil's phenotypic plasticity is represented by its flexible developmental time, its multivoltine life cycle with several overlapping generations, its capacity to feed on pollen from diverse botanical families as well as from non pollen food sources and its ability to migrate and disperse aided by winds. These characteristics make it a key pest for cotton. Probable overwintering «hot spots» for the boll weevil were identified in Misiones-Argentina, where large numbers of prediapausing weevils concentrate after arrival from newly harvested cotton fields in Paraguay, probably attracted by citrus orchards volatiles. The boll weevil's facultative quiescence is always relative to environmental adverse conditions. This suggests that overwintering in the boll weevil can be defined as «oligopause», an intermediate form of diapause. Since its introduction to Brazil in 1983, until 2006, it has spread southwest at an average of 61 km year-1 towards Argentina. However, it took the boll weevil approximately ten years to move 250 km between Paraguay and the main cotton growing area in Argentina. This slower progress is probably due to the actions taken by the Argentine government through the boll weevil eradication program. The arrival of the boll weevil at the cotton cropping areas in Paraguay and Argentina reinforces the fact that the boll weevil should finally be included in an integrated cotton pest management program jointly with other major cotton pests.El presente estudio sobre la dispersión de Anthonomus grandis Boheman, el picudo del algodonero, en Argentina, Brasil, Paraguay y Bolivia, explora las características ecológicas y fisiológicas que han permitido a

Mantle xenoliths from Nemby, Eastern Paraguay: O-Sr-Nd isotopes and trace elements of hosted clinopyroxenes

The Nemby spinel peridotites (Asuncion- Sapucai-Villarrica Graben, Central Eastern Paraguay) are variable in major element compositions, ranging from relatively 'fertile' to very depleted in basaltic component. Some of the xenoliths have exceeding high K 2 O (HK suite, distinct from the low K 2 O, LK-suite) and incompatible element (IE) contents compared with the composition of lherzolites which underwent partial melting during 'basalt-extraction'. The IE contents of clinopyroxenes encompass world-wide occurrences. This suggests that processes, other than depletion, occurred. Demarchi et al. (1988) have shown that K is mostly partitioned into glassy patches (blebs) in the xenoliths and glassy drops in clinopyroxenes. The blebs have been interpreted as derived from the breakdown of volatile-bearing wet phases, such as amphibole and/or phlogopite, which melted during ascent to the surface; the glassy drops in clinopyroxenes are generally interpreted as products of incongruent partial melting induced by decompression (Comin- Chiaramonti et al., 1986). Both probably represent the remnants of hydrous phases such as micas and/or amphiboles, and/or products induced by the influx of small-volume, volatile-rich melts (Petrini et al., 1994). In summary, most of the major element chemistry of the Nemby xenoliths (except for K 2 O and to a lesser extent for Na 2 O) are consistent with residual compositions after variable degrees of partial melting and metasomatic effects shown by alkali and IE enrichments in both whole rock and in clinopyroxene. Clinopyroxenes display variable REE enrichments, more evident in those crystals characterized by spongy texture and abundance of glassy drops. A possible explanation for the progressive enrichment of samples characterized by similar HREE and different LREE abundances is different ion-exchange processes (cf. 'simple mixing metasomatism model' of Song and Frey, 1989; Sen et al., 1993) due to the passage of LREE-rich chemical front on

Full Text Available Leporinus obtusidens Valenciennes, 1837 and L. elongatus Valenciennes, 1850 are redescribed based on the type specimens, including those of their junior synonyms, and recently collected specimens. Leporinus obtusidens is considered to be widespread, occuring in the river drainages of La Plata, São Francisco, and Parnaíba. Leporinus aguapeiensis Campos, 1945, described from the upper Rio Paraná, and L. silvestrii Boulenger, 1902, described from the Rio Paraguay, are considered junior synonyms of L. obtusidens. Leporinus elongatus is endemic to the Rio Jequitinhonha and Rio Pardo, two eastern Brazilian river basins, and the locality cited for the lectotype, Rio São Fransico, likely to be erroneous. Leporinus crassilabris Borodin, 1929, and L. crassilabris breviceps Borodin, 1929, both described from the Rio Jequitinhonha, are considered junior synynoms of L. elongatus. A new species of Leporinus, endemic to the upper Rio Paraná, very similar and sometimes mistaken with L. obtusidens, is formally described. In addition, comments on Leporinus pachyurus Valenciennes, 1850 and on L. bimaculatus Castelnau, 1855 are provided, and a lectotype for L. bimaculatus is selected.

The Brazilian-Paraguayan hydroelectric of Itaipu is considered an important milestone in the relations between Brazil and Paraguay, as it has created a permanent bond between the two countries. Nowadays, Itaipu is still one of the most important generators of electric energy in the world, being responsible for over 25 percent of the energy generated in Brazil and about 95 percent of the electricity consumed in Paraguay. The various consequences of the construction of Itaipu, in particular the changes occurred in the power balance structure in Cone Sul are phenomena that have been largely studied, and there is a multiplicity of interpretations on the theme. This paper aims to provide an overview of the relevant literature on Itaipu.

Brasiguaio Identities: An outcome of the pursuit of land across the Brazilian and Paraguayan shared border region

Directory of Open Access Journals (Sweden)

Marcos Estrada

2017-10-01

Full Text Available The movement of people between places is far from being a new or isolated phenomenon and is happening more often than before. This is also the case for individuals who moved from Brazil and Paraguay. Based on the existing literature as well as on data gathered in the landless camp Antônio Irmão, also known locally as the ‘Brasiguaios landless camp’ in Itaquiraí in the state of Mato Grosso do Sul, Brazil, this article explains how their search for a piece of land in either Brazil and Paraguay influenced the formation of the Brasiguaios identities. First, I briefly approach the foundation of transnationalism scholarship, which guided my research. Next, I demonstrate how land policies in Brazil and Paraguay, aimed at developing their respective border regions, played a role in the migration of Brazilians to Paraguayan and then the return of a number of them to Brazil. Last, I share the narrative of individuals in the Brasiguaio landless camp in the pursuit of land in either country. At the core of my argument is that the Brasiguaio identities of this landless group result from their pursuit of land rather than from migration processes.

Aportes comunicacionales para un debate sobre ciudadanía y migra Communicational contributions to a debate on citizenship and migration

Full Text Available En este trabajo se presenta un conjunto de elementos descriptivos e interpretativos acerca de la experiencia de Ápe Paraguay, un proyecto político - comunicacional que, desde 2008, realiza un grupo de migrantes paraguayos en Argentina y en Paraguay y que, progresivamente ha crecido en cantidad de miembros de otros lugares del mundo. La declaración de su propuesta política, el contenido de su página Web, así como su producción radial en Internet y otras iniciativas enmarcadas en la utilización de tecnologías de la información y la comunicación y por fuera de ellas, nos han llevado a postular una serie de inquietudes acerca de las formas de producción de ciudadanía en la actualidad, así como de la politicidad de los migrantes paraguayos organizados en distintos lugares del planeta. Estas inquietudes nos permiten vincular aspectos organizativos de los migrantes paraguayos contemporáneos, la producción y reivindicación de identidades emergentes y la utilización de medios de comunicación como forma de construcción de sujetos legítimos allí donde la historia del Paraguay ha producido lejanía y castigo. En definitiva, tratamos de recuperar, desde algunos aportes de la Antropología Cultural y del campo de las Ciencias de la Comunicación, ciertas iniciativas de producción de ciudadanía que ponen en evidencia tanto las conflictividades inherentes a los procesos migratorios y como la lucha comunicacional de los migrantes en su reclamo por el acceso a derechos.This paper presents a set of descriptions and interpretations ofthe Ápe Paraguay experience, a political-communicational project carried outin Argentina and Paraguay by a group of Paraguayan migrants since 2008 which has gradually grown due to the inclusion of members from other parts of the world.

Preliminary study on element mass fraction determination on catfish samples from Paraguay

International Nuclear Information System (INIS)

Moreira, Edson G.; Catharino, Marilia G.M.; Vasconcellos, Marina B.A.; Frutos, Sixto A.; Insaurralde, Mario S.

2013-01-01

South American catfish (Pseudoplatystoma), commonly known in Spanish as atigrado or surubi and in Portuguese as surubim or pintado is a large fish that typically reaches 1 m long and weighs 60 kg to 80 kg and may be found at the basins of the Amazon, the Sao Francisco and de la Plata rivers, usually in riverbeds and deep wells. Being a much appreciated fish for human consumption, it is quite sought after by fishermen who have been contributing to the reduction of the stocks. This fact attracted the attention of the Paraguayan authorities to the point of imposing restrictions to free fishing and commercialization. This study aims to assist the conservation efforts towards this fish by investigating its exposure to possible pollutants. Preliminary results on element determination on six samples of catfish from Paraguayan rivers are presented. Cs, Co, Fe, Se and Zn were determined by applying an Instrumental Neutron Activation Analysis method. While these element levels were lower than the legislation for human consumption, the elements As, Cr e La were not detected in the samples as they are below the detection limit of the method employed. Atomic Absorption Spectrometry was used to investigate the presence of Cd, Hg and Pb in the samples. Hg was detected in the samples while Cd and Pb were below the detection limit of the method.

Recomendação de adubação nitrogenada para trigo em sucessão ao silho e soja sob sistema plantio direto no Paraguai Nitrogen fertilizer recommendation for no-till wheat in succession to corn and soybean in Paraguay

Directory of Open Access Journals (Sweden)

Full Text Available O nitrogênio (N é um dos nutrientes mais requeridos pelo trigo e, muitas vezes, não é suprido nem na quantidade nem na época ideal. Devido à importância da adubação nitrogenada no trigo e à carência de informações disponíveis no Paraguai, foi desenvolvido este trabalho com o objetivo de propor uma recomendação nitrogenada para trigo sob sistema plantio direto. Cinco experimentos em rede foram realizados a campo, durante dois anos, em três departamentos do Paraguai, abrangendo os principais solos (Oxisols, Inceptisols e Ultisols e regiões produtoras (Alto Paraná, Itapúa e Missiones. Os tratamentos utilizados no trigo (Triticum aestivum foram cinco doses de N (0, 30, 60, 90 e 120 kg ha-1 após o milho (Zea mays e a soja (Glycine max, sendo também investigado o efeito residual de N aplicado no milho (0, 60, 120, 180 e 240 kg ha-1 na nutrição do trigo, em parcelas de 5 x 8 m, em delineamento de blocos ao acaso com três repetições. O trigo respondeu economicamente, em média, à dose de 35 kg ha-1 de N após a soja para produtividades em torno de 3.100 kg ha-1; após o milho, respondeu economicamente, em média, até 30 kg ha-1 de N, atingindo produtividade de 2.100 kg ha-1. No solo com teor de matéria orgânica maior que 4 %, verificou-se capacidade de suprir, sem adubação nitrogenada mineral, quantidade suficiente de N para alcançar produtividades de até 2.500 kg ha-1. O trigo respondeu à adubação residual de N aplicado no milho, elevando a produtividade de 1.800 (0 kg ha-1 para 2.300 kg ha-1 (com a dose estimada de 213 kg ha-1 de N aplicado no milho, na média de todos os locais.Nitrogen is one of the nutrients wheat needs most, but is often not supplied neither in the right quantity nor at the right time.

Full Text Available O objetivo deste estudo foi realizar uma análise espaço-temporal da cobertura vegetal e do uso da terra na Interbacia do Rio Paraguai Médio-MT, Brasil, pelo geoprocessamento de imagens Landsat TM, dos anos 1991, 2001 e 2011. As imagens foram georreferenciadas, classificadas e processadas no software Spring e as classes temáticas, quantificadas e editadas no software ArcGis. Foram mapeadas sete classes, sendo as mais expressivas a vegetação nativa, a pastagem e a cana-de-açúcar. Os resultados indicaram alterações em todas as classes durante os últimos 20 anos, com a diminuição de 22,89% da vegetação nativa, relacionada com o aumento de 58,42% da pastagem e 490,26% de monocultura de cana-de-açúcar. Foi verificado o conflito de uso da terra, principalmente em áreas de mata ciliar, fato que pode influenciar negativamente na conservação da interbacia e, consequentemente, do pantanal mato-grossense.This study analyzed spatial and temporal land use changes in the Middle Paraguay River Interbasin-MT, Brazil using Landsat images from 1991, 2001 and 2011. Images were geo-referenced, classified and processed using Spring software, and thematic classes were edited and quantified using ArcGis software. Seven map classes were identified, and native vegetation, pasture and sugarcane were the most significant ones. The results showed changes in all classes during the past 20 years, primarily a 22.89% decrease of native vegetation, a 58.42% increase in pasture and 490.26% increase of sugarcane monoculture. We verified land use conflicts, mostly in riparian areas, which may negatively influence Interbasin and, consequently, Pantanal conservation in the State of Mato Grosso, Brazil.

DNA barcode of Parodontidae species from the La Plata river basin - applying new data to clarify taxonomic problems

Directory of Open Access Journals (Sweden)

Elisangela Bellafronte

Full Text Available In the past years, DNA barcoding has emerged as a quick, accurate and efficient tool to identify species. Considering the difficulty in identifying some Parodontidae species from the La Plata basin and the absence of molecular data for the group, we aimed to test the effectiveness of DNA barcoding and discuss the importance of using different approaches to solve taxonomic problems. Eight species were analyzed with partial sequences of Cytochrome c oxidase I. The mean intraspecific K2P genetic distance was 0.04% compared to 4.2% for mean interspecific K2P genetic distance. The analyses of distance showed two pairs of species with K2P genetic divergence lower than 2%, but enough to separate these species. Apareiodon sp. and A. ibitiensis, considered as the same species by some authors, showed 4.2% genetic divergence, reinforcing their are different species. Samples of A. affinis from the Uruguay and Paraguay rivers presented 0.3% genetic divergence, indicating a close relationship between them. However, these samples diverged 6.1% from the samples of the upper Paraná River, indicating that the latter represents a potentially new species. The results showed the effectiveness of the DNA barcoding method in identifying the analyzed species, which, together with the morphological and cytogenetic available data, help species identification.

Full Text Available The psychology of science is a field of research emerged in the late 80’s and its basic interest is the study of the conditions determining the rise and development of scientists and researchers. However, in spite of its apparent novelty, it is feasible to find background widely disseminated in the work of previous authors. One of them is R. Ross, who wrote an article in the Paraguayan journal Letras in 1915. Ross argued that geniuses’ production is one of the most valuable potentials to which a nation can aspire and has a relevance degree higher than any kind of wealth. His argument agrees with considerations related to the subjective processes leading creative inspiration, the generation of new ideas and the relations between genius and insanity, a view that fits the ideas of the Italian physician Cesare Lombroso. The article concludes that Ross’ ideas may be identified as a distant background for the psychology of science, although it has not reached a later continuity in the work of other Paraguayan authors. The methodology adopted is both descriptive and critical, with a contextual analysis of the primary sources that are relevant to the problem.

Full Text Available The Eastern Slaty Thrush (Turdus subalaris occurs in the meridional parts of South America, from Bolivia Southward to Argentina, Paraguay and South and Southeastern Brazil. During the winter on the continent, it performs migration little known toward areas of ecotone between Amazon and Cerrado, with little information on their area of wintering in the Mato Grosso state. In this study we report on a record documenting the species for the Alto Rio Guaporé basin, Western Mato Grosso, based on a mist-netted individual. We present a record until now unpublished of the species in the region of Vila Bela da Santíssima Trindade and contribute to the knowledge of the species’ wintering range and their annual cycle.

The atomic bomb survivors emigrating in the South America were 189 in total (160 in Brazil, 4 in Paraguay, 8 in Bolivia, 14 in Argentina and 3 in Peru) in November, 1998. Ninety-three persons (49%) took a medical examination (72 in Brazil, 3 in Paraguay, 6 in Bolivia, 9 in Argentina and 3 in Peru). The mean age was 68.6 years in male, and 68.1 years in female. They had hypertension (21.5%), diabetes (8.6%), cancer (6.5%), heart disease (5.4%), and thyroid gland diseases (4.3%). The subjective symptoms with high frequency were complete exhaustion or fatigue (58.1%), loss of vigor (55.9%), heat intolerance (49.5%) and numbness or tingling (47.1%). Electrocardiogram abnormality, total protein decrement, hypercholesterolemia and corpulence were almost the same as the last time.

To generate normative data on the Symbol Digit Modalities Test (SDMT) across 11 countries in Latin America, with country-specific adjustments for gender, age, and education, where appropriate. The sample consisted of 3,977 healthy adults who were recruited from Argentina, Bolivia, Chile, Cuba, El Salvador, Guatemala, Honduras, Mexico, Paraguay, Peru, and, Puerto Rico. Each subject was administered the SDMT as part of a larger neuropsychological battery. A standardized five-step statistical procedure was used to generate the norms. The final multiple linear regression models explained 29-56% of the variance in SDMT scores. Although there were gender differences on the SDMT in Mexico, Honduras, Paraguay, and Guatemala, none of the four countries had an effect size greater than 0.3. As a result, gender-adjusted norms were not generated. This is the first normative multicenter study conducted in Latin America to create norms for the SDMT; this study will have an impact on the future practice of neuropsychology throughout the global region.

Full Text Available Varias de las carreras de Psicología que actualmente funcionan en Paraguay incluyen cátedras de Psicología Experimental en sus mallas curriculares. Uno de los objetivos de estas cátedras es la aplicación del método de la experimentación para elaborar trabajos de investigación de sus estudiantes, con lo que cumplen el doble propósito del aprendizaje didáctico y el desarrollo de conocimiento nuevo. Sin embargo, en Paraguay estas cátedras deben realizarse en medio de una escasez muy aguda de recursos e infraestructura. Este trabajo discute de manera crítica tales problemas. En primer lugar, se hace una exposición sobre los antecedentes de la Psicología Experimental en el Paraguay. Luego, se detalla la producción de los estudiantes en dos universidades haciendo especial referencia a los temas que abordan las investigaciones y el tipo de estadística utilizada.

Denial of shipments of radioactive materials in Paraguay

The Denials, Delays and Abandonment of the Radioactive Materials is a problem at world level that has been increased in the last times with more emphasis starting from the attack of September 11 the 2001 in the USA. From then radioactive materials have been denial or delayed and until abandoned. The materials of short periods used mainly in nuclear medicine as the 99m Tc or the 131 I, when they are rejected, delayed it usually causes the lost of the material because it has surpassed their useful life and in many cases they are abandoned. The rejections, delays and later abandonment of the materials in special of Medical use have originated serious damages for the nuclear medicine patients as much of diagnoses as of treatments, in Teleterapia for many patients of cancer who could not be treated. In the petroliferous prospecting and Industry has originated numerous economic damages due to the delays since most of the used sources they are of long period but the delay causes an important increase in the cost.

Migration and dispersal of Anthonomus grandis (Coleoptera: Curculionidae in South America

Directory of Open Access Journals (Sweden)

Teodoro STADLER

2007-01-01

Full Text Available El presente estudio sobre la dispersión de Anthonomus grandis Boheman, el picudo del algodonero, en Argentina, Brasil, Paraguay y Bolivia, explora las características ecológicas y fisiológicas que han permitido a este insecto dispersarse y establecerse exitosamente en América del Sur. La plasticidad fenotípica de A. grandis se caracteriza por un tiempo de desarrollo flexible, ciclo de vida multivoltino con generaciones superpuestas, la capacidad de alimentarse con polen de diversas familias botánicas así como de otras fuentes de alimento y por su habilidad para migrar y dispersarse con la ayuda del viento. Todo esto hace de esta especie una plaga clave para el cultivo del algodón. Los cultivos de cítricos en Misiones, Argentina, son posibles sitios para la hibernación de esta especie. En esta región fueron capturadas grandes cantidades de individuos prediapausantes, provenientes de algodonales en post-cosecha en Paraguay, atraídos probablemente por compuestos volátiles de cítricos cultivados en la zona. La quiescencia facultativa que atraviesan los adultos ante condiciones adversas, conlleva a un retraso en el desarrollo que se relaciona con las condiciones desfavorables. Esto sugiere que la hibernación en A. grandis puede ser definida como «oligopausa», una forma intermedia de diapausa. Desde su introducción en Brasil en 1983 y hasta el 2006, el picudo se ha dispersado en dirección sudoeste hacia Argentina, a una velocidad promedio de 61 km año-1. Sin embargo, le ha insumido aproximadamente diez años cruzar 250 km, desde Paraguay hacia el centro de la zona algodonera de Argentina. Este progreso más lento se debe probablemente a las acciones llevadas a cabo en el marco del programa de erradicación del picudo del algodonero, por parte del gobierno de Argentina. La llegada del picudo al área central de cultivo de algodón en la Argentina, así como a otras áreas de cultivo en Paraguay y Argentina, confirma el hecho de que

Full Text Available Introduction: Anti-HLA antibodies determination in the serum of patients on a waiting list for renal transplant is essential to optimize donor selection as well as for the induction and maintenance immunosuppression scheme, according to immunological risk. These antibodies could be present before transplantation as a result of being exposed to blood transfusions, pregnancies and previous transplants. The objective of the study was to determine immunization against HLA antigens, associated factors and their impact on the waiting list for a renal transplant. Methods: In this observational retrospective cross sectional study, 254 patients on the waiting list for renal transplant were included. These patients attended the Public Health central laboratory between July 2013 and July 2015. Results: 30% of the 254 studied patients presented anti-HLA antibodies. The most significant sensitizing event was the exposure to a previous transplant (p=<0.05. Multiparous women were in second place, 69% of them presenting positive PRA (panel reactive antibodies (p=<0.05. Finally 24% of poly transfused patients presented anti-HLA antibodies (p=<0.05. Conclusions: During the 2 year of the study, 51 patients were transplanted, presenting only one of them anti-HLA antibodies before transplantation. This results clearly indicate that the immunization against HLA represents a barrier for transplantation access.

Since the early 1990s, programs to control Chagas disease in South America have focused on eradicating domiciliary Triatoma infestans, the main vector. Seroprevalence studies of the chagasic infection are included as part of the vector control programs; they are essential to assess the impact of vector control measures and to monitor the prevention of vector transmission. To assess the interruption of domiciliary vector transmission of Chagas disease by T. infestans in Paraguay by evaluating the current state of transmission in rural areas. A survey of seroprevalence of Chagas disease was carried out in a representative sample group of Paraguayans aged one to five years living in rural areas of Paraguay in 2008. Blood samples collected on filter paper from 12,776 children were tested using an enzyme-linked immunosorbent assay. Children whose serology was positive or undetermined (n = 41) were recalled to donate a whole blood sample for retesting. Their homes were inspected for current triatomine infestation. Blood samples from their respective mothers were also collected and tested to check possible transmission of the disease by a congenital route. A seroprevalence rate of 0.24% for Trypanosoma cruzi infection was detected in children under five years of age among the country's rural population. Our findings indicate that T. cruzi was transmitted to these children vertically. The total number of infected children, aged one to five years living in these departments, was estimated at 1,691 cases with an annual incidence of congenital transmission of 338 cases per year. We determined the impact of vector control in the transmission of T. cruzi, following uninterrupted vector control measures employed since 1999 in contiguous T. infestans-endemic areas of Paraguay, and this allowed us to estimate the degree of risk of congenital transmission in the country.

[Brazilian colonization in the Paraguayan agricultural frontier].

Science.gov (United States)

Neupert, R F

1991-04-01

This work briefly describes Brazilian colonization of the Paraguayan agricultural frontier, analyzes factors responsible for expelling population from Brazil and for attracting Brazilians to Paraguay, and assesses the economic and social consequences of immigration to the area. Paraguay's vast and sparsely populated agricultural frontier in areas outside the Central subregion underwent a process of intense colonization from the early 1960s to the mid-1980s. The Paraguayan government initiated an ambitious colonization program in 1963 to increase production, relieve population pressure and subdivision of small parcels in the Central subregion, encourage agricultural modernization, and produce a more diversified agriculture. Paraguayan agriculture in the early 1960s suffered from excessive concentration of land in a few hands and resulting exclusion of around 3/4 of workers from ownership and from any possibility of obtaining credit to fund technological improvements. Results of studies 2 decades after implementation of the colonization plan suggest that it has failed in significant areas. Although a considerable population redistribution alleviated pressure in the Central subregion, it apparently resulted more from spontaneous movement of peasants outside the colonization areas than from the official program. Concentration of lands is now occurring in the colonization area. Assistance for agricultural modernization and diversification of production in the peasant sector has been minimal. On the other hand, production of soy, wheat, and cotton for export increased substantially, because of an entrepreneurial agriculture capitalized by foreign as well as national interests The unmet goals of the colonization program would have required structural reforms rather than simple spatial redistribution of the population. Many of the colonists in the 1970s were Brazilian families displaced by mechanized agriculture in the southern states of Parana, Santa Catarina, and Rio

Domestic gas contribution to natural radon concentration in Paraguay

International Nuclear Information System (INIS)

Coronel, G.; Sajo B, L.

1996-01-01

The technique for measuring the concentration of radon in gas sold commercially for domestic use is presented. It is shown that the contribution is not significant, 5.5±1.4 (Bq/m 3 ), nevertheless it could reach in some cases significant values of intervention (200 Bq/m 3 ). The results indicate that the additional dose to which the population is exposed is approximately 26% of the natural background calculated in approximately 0,28 mSv/year. By assuming a lineal proportionality between dose and risk, the increase of the possibility of catching lethal leukemia or cancer is 16 cases for every million of population.

Radiation protection officers in customs : an experience in Paraguay

International Nuclear Information System (INIS)

Oscar Bordon

2008-01-01

The September 11, 2001 events unleashed an offensive of the United States government to detect devices that could suppose a terrorist threat. One U.S. program entitled the Container Security Initiative affected all the customs in the world. All the countries desiring commerce with the USA must be signatory to the program; otherwise its products will not arrive to the U.S. ports. With that imposition Customs began to invest more in non-intrusive means of detection. The introduction of new equipment into the Customs environment forced the institution to enter a new area called radiation protection. The beginning was difficult due to the lack of knowledge concerning procedures in the ionizing radiation field. Not one legal regulation was known. Fortunately, the regulatory authority followed the purchase of the scanner and communicated the necessity of a license to operate and demanded that a qualified person in the radiation protection area be hired. Initially the main goal required the officer to obtain the license; however, this took some time because neither national nor international norms for scanners in Customs existed. At that time the recommendations of the regulatory authority were essential. Therefore, several procedures were adapted, thus reinforcing the necessity of specific rules for scanners in Customs. The support of the Customs director was essential. A department of radiation protection was created. Immediately a series of informative classes about radiation protection was administered producing changes in the minds of the employees, especially concerning the safety of working with ionizing radiation. This paper discusses the role of the radiation protection officer within Customs, the difficulties of this position, and the benefits that the collaboration of the officer can bring towards the construction of a safety culture in this institution.

Karyotype variability in neotropical catfishes of the family Pimelodidae (Teleostei: Siluriformes

Directory of Open Access Journals (Sweden)

Américo Moraes Neto

Full Text Available Karyotypic data are presented for four species of fish belonging to the Pimelodidae family. These species show a conserved diploid number, 2n = 56 chromosomes, with different karyotypic formulae. The analyzed species showed little amount of heterochromatin located preferentially in the centromeric and telomeric regions of some chromosomes. The nucleolus organizer regions activity (Ag-NORs and the chromosomal location of ribosomal genes by fluorescent in situ hybridization (FISH, with 18S and 5S probes, showing only one chromosome pair marked bearer of ribosomal genes, the only exception was Pimelodus britskii that presented multiple NORs and syntenic location of the 18S and 5S probes. Non-Robertsonian events, as pericentric inversion and NORs duplication are requested to explain the karyotype diversification in Pseudoplatystoma from the rio Paraguay (MS, Pimelodus from the rio Iguaçu (PR, Sorubim from the rio Paraguay (MS and Steindachneridion from the rio Paraíba do Sul (SP. The obtained data for the karyotype macrostructure of these species corroborates a conserved pattern observed in Pimelodidae. On the other hand, interspecific variations detected by molecular cytogenetics markers made possible cytotaxonomic inferences and differentiation of the species here analyzed.

As a consequence of YF outbreaks that hit Brazil, Argentina, and Paraguay in 2008-2009, a significant demand for YF vaccination was subsequently observed in Argentina, a country where the usual vaccine recommendations are restricted to provinces that border Brazil, Paraguay, and Bolivia. The goal of this paper is to describe the adverse events following immunization (AEFI) against YF in Argentina during the outbreak in the northeastern province of Misiones, which occurred from January 2008 to January 2009. During this time, a total of nine cases were reported, almost two million doses of vaccine were administered, and a total of 165 AEFI were reported from different provinces. Case study analyses were performed using two AEFI classifications. Forty-nine events were classified as related to the YF vaccine (24 serious and 1 fatal case), and 12 events were classified as inconclusive. As the use of the YF 17D vaccine can be a challenge to health systems of countries with different endemicity patterns, a careful clinical and epidemiological evaluation should be performed before its prescription to minimize serious adverse events.

The results of the ninth medical examination are reported. Atomic bomb survivors who had emigrated to South America as of November 2000 totaled 180 (153 to Brazil, 4 to Paraguay, 7 to Bolivia, 13 to Argentina, and 3 to Peru). Eighty persons (44.4%) were examined (62 in Brazil, 2 in Paraguay, 6 in Bolivia, 7 in Argentina, and 3 in Peru). The mean age of the males was 71.3 years, and the mean age of the females was 69.7 years. They had hypertension (24.1%), diabetes (10.1%), cancer (8.9%), heart disease (7.6%), and thyroid disease (2.5%). The most common manifestations of illness were fatigue (69.6%), loss of vigor (65.8%), taking medicine (55.7%), and heat intolerance (53.2%). The incident rates of electrocardiographic abnormalities and urine, blood, and biochemical tests abnormalities were almost the same as at the previous examination, and there was no change in the percentage of those who required detailed tests and treatment. When independence in daily life was judged by the criteria of the nursing care insurance system, 68 persons were judged ''independent'', and 7 persons ''handicapped.'' (K.H.)

Growing Brazilian demand to spur gas network in South America

International Nuclear Information System (INIS)

Deffarges, E.H.; Maurer, L.I.A.

1993-01-01

A recent combination in South America of economic and geopolitical factors is prompting development of a new integrated gas-pipeline network in the continent's Southern Cone. The crucial factors include privatization, regional integration, economic growth, and environmental concerns. The area, Latin America's largest regional entity, includes Brazil (population 150 million and a 1990 GNP of about $375 billion, 9th largest in the world), Argentina (population 32 million and the third largest Latin American economy after Brazil and Mexico), Bolivia, Chile, Paraguay, and Uruguay. Argentina, Brazil, Paraguay, and Uruguay are members of the MercoSur economic bloc whose objective is to develop free trade in the region. There are very few integrated pipeline networks in the world. Besides the giant North American system, with hundreds of producers and pipelines, there is only one other large integrated network. It connects continental European countries to their outside suppliers such as Norway, the C.I.S., and Algeria. The emergence of a new pipeline system is therefore important for the natural-gas industry worldwide and even more so if it occurs in a region now growing rapidly after a decade of economic difficulties

La introducción de las telecomunicaciones eléctricas en el Río de la Plata

2013-03-01

Full Text Available Las telecomunicaciones eléctricas fueron introducidas en las repúblicas del Río de la Plata entre 1864 y 1866. Primero Paraguay instaló el ferrocarril, la telegrafía eléctrica y una fundición de acero para fabricar armas y tecnología pesada. A los pocos meses, capitales británicos instalaron una red telegráfica eléctrica entre la Argentina y Uruguay, en el marco de una estrategia de desarrollo económico y de dominación imperial para establecer redes de expansión global conformadas por los telégrafos, los puertos y los ferrocarriles. Estos eventos tecnológicos se produjeron en el marco de un conflicto creciente entre facciones de Argentina, Brasil y Uruguay que desembocaron en la Guerra de la Triple Alianza contra Paraguay, conflagraciones de las que participaron, de una u otra manera, Gran Bretaña y Francia. Las guerras de soberanía rioplatense y la competencia entre potencias europeas impulsa, pues, una revolución tecnológica en el Plata en el campo de las comunicaciones.

Characterization of the early development of Pseudoplatystoma reticulatum Eigenmann & Eigenmann, 1889 (Siluriformes: Pimelodidae from the Paraguay River Basin

Directory of Open Access Journals (Sweden)

Fernanda F. Andrade

Full Text Available ABSTRACT This study described the initial development of Pseudoplatystoma reticulatum, as well as changes in growth patterns. Morphometric and meristic variables were analyzed during embryonic, larval and juvenile periods, even as allometric growth coefficients for larvae and juveniles. Eggs showed an average diameter of 1.79 mm and broad perivitelline space (23.41%. The total length (TL of the larvae ranged from 3.05 to 25.72 mm, and the total number of myomeres ranged from 45 to 50 (preanal = 13-16 and postanal = 30-35. Initial pigmentation is poor, concentrated at the extremities of the yolk sac. In the flexion stage, the pigmentation intensifies and forms a longitudinal stripe extending from the snout to the operculum and two longitudinal stripes on the body, one dorsal and the other ventral, that unite at the caudal peduncle. At first, there is a differential growth of the head and tail, and then there is the growth of the body, which shows changes in the ontogenetic priorities of feeding, swimming, and breathing capacities. Our results are very important for ecology, systematics, and hatchering, especially in terms of ontogenetic variation in morphology, growth, feeding, behavior, and mortality of P. reticulatum.

Taxonomic analysis of Paraguayan samples of Homonota fasciata Duméril & Bibron (1836 with the revalidation of Homonota horrida Burmeister (1861 (Reptilia: Squamata: Phyllodactylidae and the description of a new species

Directory of Open Access Journals (Sweden)

Pier Cacciali

2017-08-01

Full Text Available Homonota is a Neotropical genus of nocturnal lizards characterized by the following combination of characters: absence of femoral pores, infradigital lamellae not dilated, claws without sheath, inferior lamellae laterally not denticulate, and presence of a ceratobranchial groove. Currently the genus is composed of 10 species assembled in three groups: two groups with four species, and the fasciata group with only two species. Here, we analyzed genetic and morphologic data of samples of Homonota fasciata from Paraguay; according to Maximum Likelihood and Bayesian inference analyses, the Paraguay population represents an undescribed species. Additionally, morphological analysis of the holotype of H. fasciata (MNHN 6756 shows that it is morphologically different from the banded, large-scaled Homonota commonly referred to as “H. fasciata”. Given the inconsistency between morphological characters of the name-bearing type of H. fasciata and the species commonly referred to as H. fasciata, we consider them as different taxa. Thus, H. fasciata is a species inquirenda which needs further studies, and we resurrect the name H. horrida for the banded, large-scaled Homonota. The undescribed species from Paraguay is similar to H. horrida, but can be differentiated by the high position of the auditory meatus relative to the mouth commissure (vs. low position in H. horrida; and less developed tubercles on the sides of the head, including a narrow area between the orbit and the auditory meatus covered with small granular scales with or without few tubercles (vs. several big tubercles on the sides of the head even in the area between the orbit and the auditory meatus. The new species is distributed in the Dry Chaco in South America. With the formal description of this species, the actual diversity of the genus Homonota is increased to 12 species. Furthermore, we infer phylogenetic relationships for 11 of the 12 described species of the genus, based on 11

Sedimentation problems in a lateral dock on the Paraná River

Science.gov (United States)

Latessa, Gaston; Sabarots Gerbec, Martin; Arecco, Pablo

2017-04-01

The Paraná River is one of the largest water courses in the world and along its reach in the Argentine territory, it receives a large load of sediments from the Pilcomayo and Bermejo Rivers, through the Paraguay River, in the upper basin at the North of Argentina and South of Bolivia. The suspended sediment load is estimated in 100 Million ton/year. This unique characteristic drives the Paraná River morphology downstream, as well as the Paraná delta morphodynamics. On top of its natural behaviour, the Paraná-Paraguay river system is an important inland waterway transport corridor, with a significant amount of sea going vessels and inland barges navigating throughout stretches of more than 3000 Km. Consequently, there are numerous port complexes and terminals along the river banks. The typical wet infrastructure of these terminals is usually composed by jetties and quay walls, and occasionally with side or lateral docks. Whereas, the case included within this study presents all these components. This study presents a hydrodynamic and sedimentology 3D model to predict the velocity fields and the associated shear stresses that will drive morphological processes in the lateral dock. The terminal layout, side dock configuration, and sedimentation issues will be analyzed from multidisciplinary point of view, under different hydrological events and considering the correlated sediment loads. Recent bathymetry studies had been carried out and this set of data will be implemented to build the domain geometry. The flow series is as well extended with the up to date gauged flows and levels, to carry out statistical analysis and identify the design flows for different probabilities. The main objective of this analysis will be to understand and identify the scour and deposition processes and the possible problems to the structures safety and the operation of the docks, and introduce variations to the baseline design, if necessary. Results will be contrasted and validated

Full Text Available OBJETIVO: Describir las intenciones reproductivas de las mujeres paraguayas entre 1995 y 2008 y determinar las características asociadas con los embarazos no deseados e inoportunos. MÉTODOS:. Estudio descriptivo exploratorio basado en datos secundarios de las encuestas nacionales de demografía y salud reproductiva de 1995, 2004 y 2008. Se analizaron los cambios en las características sociodemográficas de las mujeres, el uso de métodos anticonceptivos y la fecundidad, así como de la proporción de nacimientos deseados, inoportunos y no deseados. Mediante dos modelos de regresión logística multifactorial se determinaron las características asociadas con los embarazos no deseados o inoportunos. RESULTADOS: En 2008, la tercera parte (33,3% de los nacimientos no fueron planeados (25,6% inoportunos y 7,7% no deseados. La edad estuvo asociada de forma directa y significativa al deseo de postergar el último nacimiento; el nivel de escolaridad se asoció inversamente con la posibilidad de tener nacimientos inoportunos; y residir en áreas urbanas, con los nacimientos no deseados. El no estar casada o unida a una pareja estable estuvo asociado con considerar el último nacimiento como no deseado o inoportuno, tanto en las mujeres solteras como en las separadas, divorciadas o viudas. CONCLUSIONES: A pesar del mejoramiento del nivel de escolaridad de las mujeres, su mayor incorporación al trabajo remunerado, el aumento del uso de métodos anticonceptivos y la disminución de la fecundidad, todavía existen grupos de mujeres que no pueden satisfacer sus ideales reproductivos y están expuestas a embarazos no deseados o inoportunos.OBJECTIVE: To describe the reproductive intentions of Paraguayan women over the period from 1995 to 2008 and determine the characteristics associated with unwanted and mistimed pregnancies. METHODS: An exploratory, descriptive study was conducted using secondary data from national demographic and reproductive health surveys from 1995, 2004, and 2008. The study examined the socio-demographic characteristics of the women, the use of contraceptive methods, and fertility, as well as the proportion of wanted, mistimed, and unwanted births. Using two multifactorial logistic regression models, the characteristics associated with unwanted or mistimed pregnancies were determined. RESULTS: In 2008, one-third (33.3% of the births were unplanned (25.6% mistimed and 7.7% unwanted. Age was directly and significantly associated with the woman having wanted to postpone her most recent birth; level of schooling was inversely related to the possibility of having mistimed births; and living in urban areas was associated with unwanted births. Not being married or in a stable relationship was associated with regarding the most recent birth as unwanted or mistimed, not only among single women, but also among those separated, divorced, and widowed. CONCLUSIONS: Despite improvements in women's levels of schooling, their increasing access to paid employment, the growing use of contraceptive methods, and reductions in fertility, there are still groups of women who are unable to fulfill their reproductive intentions and are at risk of having unwanted or mistimed pregnancies.

The group is diagnosed by the presence of a series of pinnate-shaped marks (chevrons located along the lateral midline, which extends from the humeral region to the caudal peduncle. Astyanax bopiensis nom. nov. is proposed as a substitute name for Astyanacinus multidens, which, along with Astyanax yariguies comb. nov., we reassign to Astyanax.We also propose the synonymy of Astyanacinus with Astyanax.

This article discusses the main features of the national health research systems (NHRS) of Argentina, Bolivia, Brazil, Chile, Costa Rica, Cuba, Ecuador, El Salvador, Honduras, Panama, Paraguay, Peru, Uruguay, and Venezuela, based on documents prepared by their country experts who participated in the First Latin American Conference on Research and Innovation for Health held in April 2008, in Rio de Janeiro, Brazil. The review also includes sources cited in the reports, published scientific papers, and expert opinion, as well as regional secondary sources. Six countries reported having formal entities for health research governance and management: Brazil and Costa Rica's entities are led by their ministries of health; while Argentina, Cuba, Ecuador, and Venezuela have entities shared by their ministries of health and ministries of science and technology. Brazil and Ecuador each reported having a comprehensive national policy devoted specifically to health science, technology, and innovation. Argentina, Brazil, Costa Rica, Cuba, Ecuador, Panama, Paraguay, Peru, and Venezuela reported having established health research priorities. In conclusion, encouraging progress has been made, despite the structural and functional heterogeneity of the study countries' NHRS and their disparate levels of development. Instituting good NHRS governance/management is of utmost importance to how efficiently ministries of health, other government players, and society-at-large can tackle health research.

Miguel Ciera: um demarcador de limites no interior sul-americano (1750-1760

Full Text Available In this paper, we examine the works produced by Miguel Ciera against the backdrop of the Third Delimitation Expedition, which was sent by Portugal to explore the interior of South America between 1752 and 1756. As the astronomer and cosmographer of the demarcation team, this Paduan engineer sailed up Paraguay River all the way to the mouth of Jauru River and there, with his companions, he set the border line, thus substantiating at site the Treaty of Boundaries. It was during this expedition that Ciera gathered information to design his Mappa geographicum quo flumen Argentum, Paranà et Paraguay [¿], a beautiful atlas that he later bestowed upon King Joseph I in 1758. In addition to accurate geographic charts, the atlas included depictions of fauna, popular types and landscapes made in pencil and watercolor, forming the first set of images available of that region, which was named Pantanal as from the 18th century. Here, we analyze this specific piece and seek to demonstrate that it was not merely a beautiful atlas; in fact, it was a refined visual document with which Miguel Ciera offered the Portuguese monarch valuable information about the hinterland here the border line was laid.

The results of the ninth medical examination are reported. Atomic bomb survivors who had emigrated to South America as of November 2000 totaled 180 (153 to Brazil, 4 to Paraguay, 7 to Bolivia, 13 to Argentina, and 3 to Peru). Eighty persons (44.4%) were examined (62 in Brazil, 2 in Paraguay, 6 in Bolivia, 7 in Argentina, and 3 in Peru). The mean age of the males was 71.3 years, and the mean age of the females was 69.7 years. They had hypertension (24.1%), diabetes (10.1%), cancer (8.9%), heart disease (7.6%), and thyroid disease (2.5%). The most common manifestations of illness were fatigue (69.6%), loss of vigor (65.8%), taking medicine (55.7%), and heat intolerance (53.2%). The incident rates of electrocardiographic abnormalities and urine, blood, and biochemical tests abnormalities were almost the same as at the previous examination, and there was no change in the percentage of those who required detailed tests and treatment. When independence in daily life was judged by the criteria of the nursing care insurance system, 68 persons were judged ''independent'', and 7 persons ''handicapped.'' (K.H.)

La relación entre las poblaciones y diferentes criterios de agrupación (Ambiente, País, Grupo Lingüístico y Altitud fueron evaluadas por medio de Análisis Discriminante. Se consideró el porcentaje de casos correctamente clasificados como medida de la relación entre el conjunto de variables analizadas y el criterio de agrupación.

To generate normative data for the Symbol Digit Modalities Test (SDMT) in Spanish-speaking pediatric populations. The sample consisted of 4,373 healthy children from nine countries in Latin America (Chile, Cuba, Ecuador, Guatemala, Honduras, Mexico, Paraguay, Peru, and Puerto Rico) and Spain. Each participant was administered the SDMT as part of a larger neuropsychological battery. SDMT scores were normed using multiple linear regressions and standard deviations of residual values. Age, age2, sex, and mean level of parental education (MLPE) were included as predictors in the analyses. The final multiple linear regression models showed main effects for age in all countries, such that score increased linearly as a function of age. In addition, age2 had a significant effect in all countries, except in Honduras and Puerto Rico. Models indicated that children whose parent(s) had a MLPE >12 years of education obtained higher score compared to children whose parent(s) had a MLPE ≤12 years for Chile, Guatemala, Mexico, and Spain. Sex affected SDMT score for Paraguay and Spain. This is the largest Spanish-speaking pediatric normative study in the world, and it will allow neuropsychologists from these countries to have a more accurate interpretation of the SDMT with pediatric populations.

Full Text Available ABSTRACT The tigrina Leopardus tigrinus (Schreber, 1775 is a small-sized Neotropical spotted cat found from northern Argentina and southern Brazil to Costa Rica. Four subspecies are traditionally recognized: L. t. tigrinus (Schreber, 1775 from northern Brazil, the Guianas and eastern Venezuela; L. t. pardinoides (Gray, 1867 from western Venezuela, Colombia, Ecuador and Peru; L. t. guttulus (Hensel, 1872 from southern Brazil, Paraguay and northern Argentina; and L. t. oncillus (Thomas, 1903 from Costa Rica. We studied external and craniodental morphology in quantitative and qualitative terms from 250 specimens in order to clarify the taxonomic status of tigrina. Based on the characters analyzed in this study, we recognize three diagnosable morphogroups, each with a distinct geographic distribution: northern/northwestern/west (samples from northern Brazil, the Guianas, Venezuela, Colombia, Ecuador, Peru, northwestern Argentina and Costa Rica, eastern (samples from northeastern and central Brazil, and southern (samples from southern Brazil, Paraguay and northeastern Argentina. Taking into account the morphologic evidence presented here, supported by biogeographic data and molecular studies available, we recognize three full species for tigrinas: L. tigrinus (including the putative subspecies L. t. pardinoides and L. t. oncillus as junior synonyms for northern/northwestern/west group; L. emiliae (Thomas, 1914 for eastern group; and L. guttulus for southern group.

Correlations of some Neoproterozoic carbonate-dominated successions in South America based on high-resolution chemostratigraphy

Directory of Open Access Journals (Sweden)

Alcides Nobrega Sial

Full Text Available ABSTRACT: This report reviews and incorporates new elemental and isotope chemostratigraphic data for correlation of Neoproterozoic carbonate-dominated successions in South America (Argentina, Bolivia, Brazil, Paraguay and Uruguay. These thick mixed carbonate/siliciclastic successions were largely deposited in epicontinental basins or accumulated on passive margins on the edges of cratons (e.g. São Francisco, Amazonia, Rio Apa Block, Pampia and Río de la Plata paleocontinents during extensional events related to the rifting of the Rodinia Supercontinent. From the stratigraphic point of view, these successions occur as three mega-sequences: glaciogenic, marine carbonate platform (above glaciomarine diamictites or rift successions, and dominantly continental to transitional siliciclastics. In the orogenic belts surrounding cratons, carbonate-dominated successions with important volcanoclastic/siliciclastic contribution have been, in most cases, strongly deformed. The precise ages of these successions remain a matter of debate, but recently new paleontological and geochronological data have considerably constrained depositional intervals. Here, we report high-resolution C, O, Sr, and S isotope trends measured in well-preserved sample sets and mainly use Sr and C isotopes in concert with lithostratigraphic/biostratigraphic observations to provide detailed correlations of these successions. The establishing of a high-level and definite chemostratigraphic correlation between Neoproterozoic basins in South America is the main goal of this work.

Political Economy of Brazilian foreign policy: nuclear energy, trade, and Itaipu

International Nuclear Information System (INIS)

Soares de Lima, M.R.

1986-01-01

This dissertation advances an analytical framework intended to account for the international strategies of semi-peripheral countries: those industrialized Third World countries able to manufacture and export industrial goods. The empirical validation of the proposed framework was assessed through five case studies of Brazil's conduct in the following issue areas: nuclear energy, trade, and hydroelectric development of the Parana River Basin. A free-rider strategy was observed in the case of the nonproliferation regime. The decision to attain nuclear self sufficiency through the 1975 agreement with West Germany conforms to what was defined as unilateral behavior. Brazil's activism on behalf of Third World demands in North South negotiations as they impinge upon trade matters was accounted for in terms of the existence of private gains accruing from participation in that collective endeavor. Compliance with a regime's rules resulting from the use or threat of use of coercion was observed in the case of multilateral trade negotiations. The last case study examines a pattern of behavior defined as a hegemonic. In the development of a regime for the utilization of the Parana River Basin's hydroelectric potential, Brazil provided positive incentives to its junior partner (Paraguay) and negative inducements to the uncooperative partner (Argentina)

Abstract This synopsis provides an identification key to the genera of Tribe Lachnophorini of the Western and Eastern Hemispheres including five genera previously misplaced in carabid classifications. The genus Asklepia Liebke, 1938 is revised with 23 new species added and four species reassigned from Eucaerus LeConte, 1853 to Asklepia Liebke, 1938. In addition, a new genus is added herein to the Tribe: Peruphorticus gen. n. with its type species P. gulliveri sp. n. from Perú. Five taxa previously assigned to other tribes have adult attributes that make them candidates for classification in the Lachnophorini: Homethes Newman, Aeolodermus Andrewes, Stenocheila Laporte de Castelnau, Diplacanthogaster Liebke, and Selina Motschulsky are now considered to belong to the Lachnophorini as genera incertae sedis. Three higher level groups are proposed to contain the 18 recognized genera: the Lachnophorina, Eucaerina, and incertae sedis. Twenty-three new species of the genus Asklepia are described and four new combinations are presented. They are listed with their type localities as follows: (geminata species group) Asklepia geminata (Bates, 1871), comb. n, Santarém, Rio Tapajós, Brazil; (hilaris species group) Asklepia campbellorum Zamorano & Erwin, sp. n., 20 km SW Manaus, Brazil, Asklepia demiti Erwin & Zamorano, sp. n., circa Rio Demiti, Brazil, Asklepia duofos Zamorano & Erwin, sp. n., 20 km SW Manaus, Brazil, Asklepia hilaris (Bates, 1871), comb. n, São Paulo de Olivença, Brazil, Asklepia grammechrysea Zamorano & Erwin, sp. n., circa Pithecia, Cocha Shinguito, Perú, Asklepia lebioides (Bates, 1871), comb. n, Santarém, Rio Tapajós, Brazil, Asklepia laetitia Zamorano & Erwin, sp. n., Leticia, Colombia, Asklepia matomena Zamorano & Erwin, sp.n., 20 km SW Manaus, Brazil; (pulchripennis species group) Asklepia adisi Erwin & Zamorano, sp. n., Ilha de Marchantaria, Lago Camaleão, Brazil, Asklepia asuncionensis Erwin & Zamorano, sp. n., Asunción, Río Paraguay

We report on a 4-year-old boy adopted from Paraguay who presented with an acute onset of thigh pain. Initial clinical, imaging, and histopathologic findings suggested florid osteomyelitis. However, the development of pancytopenia on intravenous antibiotics prompted further investigation and the ultimate diagnosis of Gaucher disease. In retrospect, characteristic changes on conventional radiographic and MR images, as well as growth of a contaminant organism, pointed to the diagnosis of pseudo-osteomyelitis rather than osteomyelitis.

Public participation in watershed management: International practices for inclusiveness

Science.gov (United States)

Perkins, Patricia E. (Ellie)

This paper outlines a number of examples from around the world of participatory processes for watershed decision-making, and discusses how they work, why they are important, their social and ecological potential, and the practical details of how to start, expand and develop them. Because of long-standing power differentials in all societies along gender, class and ethnic lines, equitable public participation requires the recognition that different members of society have different kinds of relationships with the environment in general, and with water in particular. From a range of political perspectives, inclusive participatory governance processes have many benefits. The author has recently completed a 5 year project linking universities and NGOs in Brazil and Canada to develop methods of broadening public engagement in local watershed management committees, with a special focus on gender and marginalized communities. The innovative environmental education and multi-lingual international public engagement practices of the Centre for Socio-Environmental Knowledge and Care of the La Plata Basin (which spans Brazil, Argentina, Uruguay, Paraguay and Bolivia) are also discussed in this paper.

In aquatic systems, bottom sediments have often been considered as the main methylmercury (MeHg) production site. In tropical floodplain areas, however, floating meadows and flooded forests extend over large areas and can be important Hg methylating sites. We present here a cross-system comparison of the Hg net methylation capacity in surface sediments, flooded soils and roots of floating aquatic macrophytes, assayed by in situ incubation with 203Hg and extraction of formed Me203 Hg by acid leaching and toluene. The presence of mono-MeHg was confirmed by thin layer chromatography and other techniques. Study areas included floodplain lakes in the Amazon basin (Tapajós, Negro and Amazon rivers), the Pantanal floodplain (Paraguay river basin), freshwater coastal lagoons in Rio de Janeiro and oxbow lakes in the Mogi-Guaçú river, São Paulo state. Different Hg levels were added in assays performed in 1994-1998, but great care was taken to standardise all other test parameters, to allow data comparisons. Net MeHg production was one order of magnitude higher (mean 13.8%, range 0.28-35) in the living or decomposing roots of floating or rooted macrophyte mats (Eichhornia azurea, E. crassipes, Paspalum sp., Eleocharis sellowiana, Salvinia sp., S. rotundifolia and Scirpus cubensis) than in the surface layer of underlying lake sediments (mean 0.6%, range 0.022-2.5). Methylation in flooded soils presented a wide range and was in some cases similar to the one found in macrophyte roots but usually much lower. In a Tapajós floodplain lake, natural concentrations of MeHg in soil and sediment cores taken along a lake-forest transect agreed well with data on net methylation potentials in the same samples. E. azurea, E. crassipes and Salvinia presented the highest methylation potentials, up to 113 times higher than in sediments. Methylation in E. azurea from six lakes of the Paraguay and Cuiabá rivers, high Pantanal, was determined in the 1998 dry and wet seasons and ranged from

Genus Astyanax is well distributed in Neotropical freshwater environments and its taxonomic position is uncertain, as is the case with other Characidae genera allocated in the group incertae sedis. This study aimed to analyse the karyotype of different populations of Astyanax fasciatus (Corumbataí River basin) using Giemsa staining, C-band technique, and fluorescence in situ hybridization for the H3 histone and 5S rRNA genes, in addition we describe for the first time the chromosomal organization of H3 histone and 5S rRNAgenes in A. marionae (ParaguayRiver basin). Chromosomes of three A. fasciatus populations were analysed (two with 2n = 50 and one with 2n = 48) and the heterochromatin was organized in two forms (blocks with blurred boundaries and distinct blocks). H3 histone and 5S rRNA genes were observed in all the three populations of A. fasciatus on two chromosome pairs (one metacentric chromosome showing H3 histone and 5S rRNA gene clusters). In A. marionae (2n = 48), H3 histone and 5S rRNA genes were observed in one acrocentric chromosome pair (different pairs). Further, differences between karyotypes and heterochromatin, as well as the chromosomal organization of H3 histone and 5S rRNA genes in Astyanax species, focussing on chromosome evolution in the group are discussed.

The health of the world's freshwater ecosystems is fundamental to the health of people, plants and animals around the world. The sustainable use of the world's freshwater resources is recognized as one of the most urgent challenges facing society today. An estimated 1.3 billion people currently lack access to safe drinking water, an issue the United Nations specifically includes in its recently published Millennium Development Goals. IBM is collaborating with The Nature Conservancy and the Center for Sustainability and the Global Environment (SAGE) at the University of Wisconsin, Madison to build a Modeling Collaboration Framework and Decision Support System (DSS) designed to help policy makers and a variety of stakeholders (farmers, fish and wildlife managers, hydropower operators, et al.) to assess, come to consensus, and act on land use decisions representing effective compromises between human use and ecosystem preservation/restoration efforts. Initially focused on Brazil's Paraguay-Parana, China's Yangtze, and the Mississippi Basin in the US, the DSS integrates data and models from a wide variety of environmental sectors, including water balance, water quality, carbon balance, crop production, hydropower, and biodiversity. In this presentation we focus on the collaboration aspects of the DSS. The DSS is an open environment tool that allows scientists, policy makers, politicians, land owners, and anyone who desires to take ownership of their actions in support of the environment to work together to that end. The DSS supports a range of features that empower such a community to collaboratively work together. Supported collaboration mediums include peer reviews, live chat, static comments, and Web 2.0 functionality such as tagging. In addition, we are building a 3-D virtual world component which will allow users to experience and share system results, first-hand. Models and simulation results may be annotated with free-text comments and tags, whether unique or
