    Full Text Available Se presentan los resultados obtenidos del estudio de instrumentos de molienda recuperados en la Excavación I del montículo A del sitio Guardia del Monte -laguna de Castillos- Uruguay. Para realizar el trabajo se procedió a la caracterización de los instrumentos de molienda mediante el relevamiento de los atributos físicos y de las características funcionales. Para esto último se aplicó la Técnica de Extracción e Identificación de Partículas Biosilíceas, con el objetivo de realizar correlaciones entre instrumentos particulares y tipos de recursos vegetales específicos. Asimismo, se emplearon fuentes escritas profundizando en los aspectos relacionados con la molienda y uso de recursos vegetales. Los resultados obtenidos permitieron identificar el procesamiento de vegetales con aplicaciones alimenticias (preparación de harinas, bebidas fermentadas, etc. y tecnológicas (textilería, cordelería, cestería, entre los que se identificaron recursos silvestres y cultivados o manejados. Algunos instrumentos presentaron evidencias de procesamiento de recursos alimenticios, otros de recursos tecnológicos y finalmente otros con indicios de multifuncionalidad. Asimismo, se constató una cierta correlación entre algunos de los atributos físicos de los instrumentos y la funcionalidad atribuida a partir de los vegetales identificados y los usos referidos en las fuentes etnográficas.This paper presents the results from studies performed on milling stone tools recovered at Excavation I, Mound A from Guardia del Monte Site, Castillos lagoon, Uruguay.

  3. Lithogeochemistry the Rocha formation, SE Uruguay: tectonic implications

    International Nuclear Information System (INIS)

    The Rock Formation in the eastern portion of Lot Cleaver Dionisio, eastern coast of Uruguay, is a thick sedimentary sequence of turbiditic origin, metamorphosed under conditions of low grade and intensely deformed. Literature data indicate age of sedimentation between 590 and 570 Ma, and intrusion of granitoids at ca. 550 Ma samples representing metarenites and pelitic rocks of this unit were analyzed for determination of major and trace elements, including rare earth elements. The lithogeochemical data strongly suggest that: The protolith of the Rock Formation originated from felsic sources, upper continental crust; The environment of deposition is likely continental passive margin , but with a contribution of continental arc . Consistency with the lithogeochemical data corresponding to the sedimentary sequence of the upper portion of the Oranjemund Group (literature data), in SW Africa, corroborates the hypothesis of African affinity for these sediments. These results would be consistent with a tectonic evolution of a distal portion of the African continental margin turbidites with for approaching an active continental margin with bow

    International Nuclear Information System (INIS)

    The studied area is located between Lascano city and Sierra de los Ajos hills (department of Rocha, East Uruguay). It is represented by volcanic deposits correspondent to Puerto Gomez and Arequita Formations which are exposed as remarkable and preserved hills in areas recovered by Cenozoic sediments and wetlands. Detailed geological mapping allowed the descriptive characterization of eight volcanic facies: five coherent facies and three volcaniclastic facies. Several structural lineaments located in a constrictive framework, according to the transcurrent system represented by the northeastern portion of the Santa Lucia - Aigua - Merin tectonic corridor (SaLAM), were identified. These lineaments (Bella Vista, India Muerta and Los Ajos) controlled the tecto-magmatic arrange in this portion of the basin, determining petrographic and structural differences in the area. Particularly, to the East of the India Muerta with structural trend No.20 felsic lavas correspondent to the Sierra de los Ajos and related volcaniclastic deposits are present. On the other hand to the West, intermediate to felsic lavas occurred and no volcaniclastic deposits have been yet identified

    Full Text Available This article analyzes the development model of the Atlantic coast of Uruguay and its capacity to preserve relevant ecosystem services. The chosen study area was Playa Solari – Barra, one of the most important touristic spots of Uruguay (located in Laguna de Rocha, Rocha, Uruguay. This coastal zone has experienced important territorial changes during the last decades, with conflicts arising among traditional urban development for beaches, the recent strategies of rural-coastal tourism and natural and cultural heritage conservation strategies. The results show that the strong process of urban consolidation is negatively affecting the most important economic resources and ecosystem services in the study area, particularly those that directly promote touristic activities. For the last five years, the trend of urban development seems to point out towards an increase of the observed negative effects. Based on that evidence, this paper proposes specific strategies, particularly a new land use model, to revert negative impacts.Se analiza la capacidad del modelo de desarrollo de la costa atlántica del Uruguay para preservar los recursos que lo sustentan. Se estudia el sector de Playa Solari - Barra de Laguna de Rocha, zona con importantes dinámicas territoriales, conflictos entre el desarrollo urbano tradicional de balneario, las nuevas modalidades de turismo rural-costero y la protección de sus recursos. A través de comparación de imágenes aéreas históricas, opinión de usuarios, estudio de normativa entre otros, se investigan servicios ecosistémicos existentes, usos antrópicos y un escenario posiblemente tendencial. Los resultados evidencian una notoria etapa de consolidación urbana y un proceso histórico de ocupación y usos que perjudica a los principales recursos del desarrollo económico de la zona. Finalmente se proponen recomendaciones y una clasificación primaria de suelos con usos y ocupaciones alternativos a los actuales, as

    1988-06-01

    Uruguay, officially "The Oriental Republic of Uruguay," is a country of 176,215 sq km with a temperate climate and a good water supply, which contributed to the emergence of stock raising as the economy's traditional base. 1.31 million of the country's 2,940,200 people live in Montevideo, the capital and only large city. The population is 85%-95% white and 66% Roman Catholic. The dominant culture and official language is Spanish, although 25% of the people are of Italian origin. The annual population growth is only 0.5%, due to a low birth rate and large net outmigration. Infant mortality in 1986 was 27.1/1000, and life expectancy was 73 years. Literacy is 96%, due to an extensive system of public and private education. There is a large, urban middle class, which enjoys a high standard of living. 22% of the work force is in industry, 21% in government, 15% in commerce, and 28% in services. The 1986 gross domestic product was $6.2 billion, per capita $1701. The annual growth rate is now 6.3%, which is an upturn from the generally stagnant economic conditions of the last 30 years. 1986 exports were $834 million (mainly meat, wool, hides, and leather goods); imports were $870 million. Inflation averages 76.4%, and 270 pesos=$1.00. The major economic problem is managing the huge external debt of almost $5.4 billion. In 1987 Uruguay reached a debt rescheduling agreement with creditor banks and the International Monitary Fund, stretching out repayment dates through 2004. Exchange rates were allowed to float in 1982, and the country is trying to reduce the burden of the excessively large government sector through various privatization schemes. Uruguay has also been working with Argentina and Brazil toward integrating their economies. The only aboriginal inhabitants of Uruguay were the Charrua Indians. In 1811 Jose Gervasio Artigas led Uruguay's revolt against Spain, and total independence was achieved in 1828. Jose Batlle y Ordonez, who served as president from 1903 to

    The tectonic evolution of Uruguay is presented from the synthesis of the geological evolution. It will be show the evolution of different orogenic cycles including the evolution of magmatism, deformation and associated metamorphism, which affected these latitudes emphasizing the paleogeographic context. are recognized in the Uruguayan territory several orogenic cycles , shorter events associated with the movement of fluid reactivation fault zones, inter alia, that with isotope studies mainly those made ​​in the past 15 years have improved the understanding and evaluating durations different tectonic events and associated phenomena. Structural provinces of the platform South America are characterized according to their origin in cratonic areas , orogenic belts and basins sedimentary . Cratons represent stable regions consisting of Precambrian rocks . During cycles orogenic these areas behaved as rigid regions, mobile belts that developed around him and were eroded and exhumed . South America was involved in events amalgamation and breakup of supercontinents during several consecutive orogenic cycles that occurred in the Paleoproterozoic (Atlantis or supercontinent Columbia), Mesoproterozoic (supercontinent Rodinia or paleopangea), Neoproterozoic (western Gondwana) and Carboniferous (Pangaea). Evidence attempt supercontinent Columbia suggests that existed between 1800 and 1500 Ma prior to the period of rapid growth mantle and cortical reorganization. In these latitudes the beam of mafic dikes (1700 Ma) granites with anorogenic (rapakivi) could represent the fragmentation of this supercontinent or episode tafrogénico Stateriano. The geodynamic evolution of the crust during the Late Proterozoic and Paleozoic less involved the formation of two great continents, Laurentia and Gondwana, from fragmentation Rodinia supercontinent that would have formed ca. 1100 Ma and would have dismembered into three fragments between 800 and 600 Ma during the Pan - African orogeny

    Full Text Available En 2013 se realizó una investigación cualitativa en El Castillo, comuna de La Pintana, Santiago, Chile, que tuvo como referente los conceptos de "espera" y de "territorios de la espera". La Pintana fue creada en 1981 en el marco de las reformas urbanas neoliberales de la dictadura, con el fin de acoger población erradicada. Se entiende la espera como una situación generada a partir de desplazamientos de población que se instala (o es instalada a vivir en un territorio deficitario que no mejora, así como tampoco mejora la condición socioeconómica de sus habitantes. Se concluye que El Castillo es un territorio y una sociedad de la espera. Esta condición define el lugar, la identidad y las prácticas espaciales de sus habitantes. Sin embargo, la forma y contenido de la espera varía según generaciones: en los jóvenes, una espera esperanzada; y en los adultos y viejos, una espera resignada y nostálgica.

The piece lacks of an archaeological context, is difficult assigning it a precise chronology. Presumably it is a stele-menhir that we analyze it within the geographical area of the set in the Middle Tagus Basin and San Vicente Mountains.We suggest some interpretations and hypothesis about the posible dating and meaning while we are conscious that there are some constraints arising from the scant knowledge and rare documentation of that geographical zone. We can only with puntual findings and references wich can not allow definitive conclusions to be drawn on its chronology and function. However we believe the analysis of available data for this piece support the proposal for a partnership on the stele-menhirs and the funeral structures for the geografical area analyzed.

  18. Modeling of a Modified Rocha Slot Test in welded tuff

    Energy Technology Data Exchange (ETDEWEB)

    Blanford, M.L.; Zimmerman, R.M.

    1987-12-31

    The design of nuclear waste repositories in hard rock underground requires an understanding of how the jointed rock mass responds to the various loads introduced. The Nevada Nuclear Waste Storage Investigations (NNWSI) is conducting a series of field tests in G-Tunnel on the Nevada Test Site to characterize the behavior of welded tuff. In particular, one of the ways its modulus of deformation is being measured in situ is by means of a slot loaded by a pressurized flatjack. This is called the Modified Rocha Slot Test, after Manuel Rocha who pioneered investigations using this type of test. Numerical calculations were undertaken using the stress-wave dynamic finite difference code STEALTH. Using dynamic relaxation, the code is able to follow the quasi-static loading curve quite closely, so that the path-dependent aspects of the solution are captured economically. The material model (CAVS) represents an elastic-plastic rock matrix with evenly-spaced joints in three mutually perpendicular planes. The joints have nonlinear normal compliance, shear cohesion, and shear strength that depend on the slip history. Slip-induced dilation of the joints is also taken into consideration. Results of the calculations are presented which illustrate the stresses, deformations, and joint slippages resulting from the application of pressure loading in the slot. The stress field is remarkably sensitive to joint orientation and cohension, but rather insensitive to the normal compliance. The effect of a confining in situ stress field is also examined.

    Pereira, Gisela; Maneyro, Raúl

    2016-08-01

    This study describes the reproductive microhabitat of Melanophryniscus montevidensis and its use in two water bodies (WBs) in Barra de la Laguna de Rocha, Uruguay. Monthly field trips were performed between March 2012 and February 2013. Variables related to the WBs and vegetation, as well as parameters linked to the usage the amphibians make of the site (e.g: distance to the border of the pond, water depth and the vegetation use) were recorded. The behavior shown by the individuals during the breeding activity was recorded. This activity occurs in shallow temporary WBs with abundant hydrophilic vegetation. The individuals were found more frequently in areas near the edge of the pond, which has denser vegetation. The calling males were found closer to the border of the pond, and they showed better body condition than the non-calling males. In addition to calling activities, males used alternative tactics to find couples, such as active search of females, and aggressive behaviors, such as male displacing and physical combat. Such behaviors are common in anurans with explosive reproductive dynamics. The characterization of the reproductive microhabitats permits the proposal of strategies for the conservation of the species in Uruguay, given that the loss and fragmentation of habitats is one of the main causes considered for the decrease in their populations.

  7. Uranium-series isochron dating at El Castillo Cave (Cantabria, Spain): The "Acheulean"/"Mousterian" question

    Science.gov (United States)

    Bischoff, J.L.; Garcia, Jose Francisco; Straus, L.G.

    1992-01-01

    A massive flowstone layer, Level 23, near the base of the stratigraphic sequence in El Castillo Cave (Cantabria, Spain), is dated by the uranium-series isochron method to 89+11/-10 ka bp. The flowstone separates cultural layers traditionally labelled "Mousterian" (above) and "Acheulean" (below). The date reported here, in association with other recent age determinations for "Mousterian" and "Acheulean" artifact assemblages in Western Europe, calls into question the temporal significance of these archaeological designations. In addition, it further underlies the importance of the Castillo cultural sequence and allows tentative discussion of changing rates of sedimentation in the vestibule of the cave, where some 18 m of cultural and geological deposits were laid down during the course of the Upper Pleistocene. ?? 1992.

  13. Uruguay declared free of Chagas disease transmission.

    Science.gov (United States)

    1998-06-01

    According to 1997 entomological and sero-epidemiological data, the transmission of Chagas disease has been interrupted in Uruguay; this has been certified by an independent commission appointed by the Pan American Health Organization/World Health Organization (PAHO/WHO). Transmission of Chagas disease, which is endemic in Uruguay, is via the vector Triatoma infestans or through transfusion with infected blood. In 1983, T. infestans lived in dwellings in 80% of Uruguay; in 1996, in all departments except Tacuarembo, house infestation rates decreased to below 0.1% (a reduction equivalent to 95%). The vector is found around the home, rather than in it, in Tacuarembo; therefore, its presence does not have any significance for transmission. The number of infected blood donors is now negligible, and there is 100% coverage via compulsory blood screening. Uruguay is the first Southern Cone country to have achieved the goals established by the Ministries of Health of Argentina, Bolivia, Brazil, Chile, Paraguay, and Uruguay to eliminate the transmission of Chagas disease.

  18. Direct radiocarbon dates for prehistoric paintings at the Altamira, El Castillo and Niaux caves

    International Nuclear Information System (INIS)

    Among things that most strikingly distinguish modern humans from other hominids and the rest of the animal kingdom is the ability to represent things and events pictorially. Complex paintings of the type discovered in the Altamira, El Castillo, Niaux and Lascaux caves represent an important stepping stone in the cultural evolution of humankind. Until now dates were derived from style or dated remains left by prehistoric visitors and could be biased by prolonged occupation or visits unrelated to painting activity. Here we report the first radiocarbon dates for the charcoal used to draw stylistically similar bisons in these caves: 14,000 ± 400 yr BP in the Spanish caves of Altamira, 12,990 ± 200 yr BP in El Castillo, and 12,890 ± 160 yr BP for a bison of different style in the French Pyrenean cave of Niaux. Our results demonstrate the imprecise nature of stylistic dating and show that painting dates derived from remains of human activities should be used with caution. (Author)

    Full Text Available A etapa de polimento de rochas ornamentais ocorre em politrizes, as quais podem ser semi-automáticas ou automáticas. Em ambas as máquinas, a velocidade de rotação do satélite é invariável, e, por consequência, a velocidade de corte, que é a distância percorrida por um rebolo abrasivo em função do tempo, permanece constante. A possibilidade de se alterar a velocidade com que o rebolo abrasivo passa sobre a superfície da chapa de rocha pode permitir uma otimização desse processo. Para esta pesquisa foram definidas 24 situações operacionais distintas, nas quais variou-se a pressão de carregamento (1 e 2 kgf/cm2, velocidade de rotação de satélite (300, 400, 500 e 600 rpm e a exposição do satélite sobre a rocha (1, 2 e 3. Para isso, foi instalado um inversor de frequência em uma politriz semi-automática que possibilitou a variação da velocidade de rotação de satélite para realização dos experimentos. Assim, foram realizados os testes de polimento, sendo cada rocha submetida a 10 sequências de rebolos abrasivos do tipo magnesiano, a saber: 24, 36, 60, 120, 220, 400, 600, 800, 1200 e lustro, totalizando 720 amostras. Os resultados mostraram que no sistema tribológico existente no polimento de rochas ornamentais a variável rocha atua como elemento ativo, influenciando no desgaste do rebolo abrasivo e exibindo brilho de acordo com as propriedades petrográficas.

    2013-01-01

    A little more than a quarter-century ago, I received an inquiry from a young Assistant Professor of Applied Mathematics at the University of Tulsa, the honoree of this volume, Carlos Castillo-Chavez. Though he was well situated in a faculty job, he was not satisfied: He was interested in mathematical biology, having written an excellent thesis in population biology with Fred Brauer at Wisconsin entitled Linear and Nonlinear Deterministic Character-Dependent Models with Time Delay in Population Dynamics. But that success had only whetted his appetite to become more deeply embedded in biology, and he was prepared to give up his faculty job to start a postdoctoral fellowship in ecology. It is always difficult to read in such letters what potential exists in the author; but there was something about what Carlos wrote, the obvious sacrifice he was prepared to make, and my regard for Fred Brauer that convinced me that I must meet this fellow. We did meet, for lunch in an LA restaurant, and the qualities that have led to his remarkable career were immediately obvious. I resolved on the spot to make sure he joined our group. Carlos arrived at Cornell shortly thereafter, and did not leave for nearly twenty years. PMID:24245645

The analysis pretends to get complementary information to the previous one obtained from the archeological research done at these places. The results obtained from the mortars tested, from foundations or pavem.ent, shoves their differences that can be associted to variables as location, age of construction and utility. The conclusions are a base for later analysis to modeling the construction knowledge in both settings.

    Full Text Available En el ámbito académico se expone la violencia como un problema asociado a los hechos delictuales en el ámbito ciudad, obviándose otras formas de violencia que operan en este contexto tales como la violencia simbólica. Ésta, aplicada a la comprensión de las realidades barriales de la ciudad de Santiago, hace posible observar en la configuración de estigmas territoriales, identidades deterioradas de carácter colectivo que se imponen sobre ciertos barrios de la ciudad, considerados reductos de delincuencia y pobreza. En este contexto, el objetivo de este artículo es aproximarse al estigma territorial como forma de violencia simbólica a través de las percepciones de habitantes de un sector estigmatizado de la ciudad de Santiago de Chile, concretamente habitantes del sector El Castillo de la comuna de La Pintana. Este artículo es producto de un estudio exploratorio y de carácter cualitativo, para el cual se realizaron 20 entrevistas semi-estructuradas. Entre los principales resultados se encuentran el reconocimiento de los habitantes de ser encasillados con estigma a condición de habitar un barrio determinado, por un lado, y la lucha de combatir el estigma creando una nueva identidad territorial, por otro.

    Full Text Available Cyanobacterial blooms are a worldwide environmental problem. This phenomenon is typically associated with eutrophication (nutrient enrichment and changes in hydrology. In this study we analysed the distribution of planktonic cyanobacteria in Uruguay and their toxins (microcystin, saxitoxin and cylindrospermopsin, working with an interagency team (OSE, DINAMA, IM, University of the Republic and IIBCE. An historical data base (n = 3061 for 64 ecosystems, years 1980-2014 was generated. Differences between lotic and lentic ecosystems were found in terms of chlorophyll a and nutrient concentrations, usually indicating eutrophication. Two geo-referenced maps for the country were generated with cyanobacteria biomass indicators and the most relevant toxin (microcystin, according to risk levels suggested by the World Health Organization for recreational waters. The areas of greatest risk of exposure were the reservoirs of large rivers (Uruguay and Río Negro and Río de la Plata beaches. In the second part of the study, up to 20 mg L-1of microcystin was quantified in bloom (scum samples, as well as the presence of genes that suggest more microcystin varieties, potentially with greater toxicity. This study provides basic information about the distribution of cyanobacteria in Uruguayan freshwaters that will be useful for national monitoring programs and scientific research.

    Full Text Available Argentina y Uruguay están entre los países con mayor proporción de mujeres jóvenes fumadoras. Se desconoce cuál es la proporción exacta de ellas que fuman durante el embarazo así como las características de las que dejan de fumar y las que continúan fumando durante el embarazo. Realizamos una encuesta administrada por un/a entrevistador/a a 1512 mujeres embarazadas de 18 años o mayores (796 en Argentina; 716 en Uruguay, que concurrían a control prenatal en hospitales públicos de grandes conglomerados urbanos. 44% de las mujeres en Argentina y 53% en Uruguay habían sido o eran fumadoras. Durante el embarazo, 11% de las mujeres en Argentina y 18% en Uruguay continuaron fumando. En ambos países, la proporción de mujeres que vive con fumadores, permite fumar en el hogar y regularmente o siempre se encuentra en lugares cerrados con personas que estén fumando fue 49%, 46% y 20% entre las mujeres que nunca fumaron, 67%, 60% y 32% entre las que dejaron, y 78%, 75% y 52% entre las que continuaron fumando respectivamente. El estudio confirma un importante problema de salud pública y documenta que la exposición ambiental persiste en subgrupos de mujeres, aun en aquéllas que dejaron de fumar.

  14. Mining in Uruguay: Potential and challenges

    International Nuclear Information System (INIS)

    We discuss the geological, economic and environmental feasibility of mining in Uruguay. Whereas the present contribution of mining to GDP of Uruguay is only 0.33%, this contribution would grow in 2015 to between 2 and 5.4% (depending on the price of iron ore) as a result of the implementation of new projects. The mining operations and short term projects include mainly limestone for cement and lime, gold, agate, amethyst and iron. Another set of resources, such as black sands, dolomite, manganese and talc, still require geological and / or economic feasibility studies. To develop sustainable mining, it is indispensable human resource training, especially more geologists, mining technicians and skilled operators. Several reasons make it imperative to develop our mineral resources: diversification of the production, development of neglected areas, decentralization, creation of industrial chains and employment generation. On this last point, mining creates ca. 20 times more jobs than extensive livestock per unit area. It is also shown that, in the example of metallic minerals and cement, earnings of mining companies are ca. 1000 times larger than those of extensive livestock per hectare. The current legal framework is considered sufficient, and is in the enforcement of these regulations where emphasis should be placed. It is necessary to create a state agency to assume the functions of a Geological Survey, conducting basic and applied geological research. This body should be independent of that responsible for the management of mineral resources, as in the example of Brazil (CPRM and DNPM). From the environmental point of view we present examples of successful recovery of land previously dedicated to mining in neighboring countries. Caring for the environment is in fact implicit in all mining projects now, given the current legislation. We suggest the creation of a guarantee fund for the recovery of mining areas and the use of funds raised from mining royalties for

  20. Precambrian terranes of African affinities in the southeastern part of Brazil and Uruguay

    International Nuclear Information System (INIS)

    distinct, representing the main suture that separates the terranes of African and South-American affinities. As observed in figure 1, it is considered in this article that the region of African affinity is constituted by the terrains located east of the Major Gercino-Sierra Ballena suture zone, being represented by two major units: the Granite Belt - outcropping along the whole eastern portion of the Brazilian southern region, and the Punta del Este terrain (PET) south-easternmost of Uruguay. The Punta del Este Terrane (PET) is composed of a series of gneisses and migmatites formed in the 1000-900 Ma interval, according to Preciozzi et al. (1999; Basei et al 2000), intensely reworked during the Rio Doce orogeny (600-500 Ma). These authors proposed that the terranes situated east of the Alferes-Cordilheira Shear Zone should not integrate the Granite Belt, suggesting that this crustal segment represent in South America terranes related to the Namaqua Belt recognized in the southwestern portion of the African continent. Similar terranes have not been recognized in Brazil and Argentina. In PET, three major tectonic units can be characterized: a gneissic-migmatitic basement, a low-grade metasedimentary cover (Rocha Group) and a post-tectonic series that includes alkaline granitoids and acid volcanic rocks. Considering that the PET basement correlates with the Namaqua Complex gneisses, the Rocha Group was tentatively correlated with the Gariep Group supracrustal units (au)

  6. Recent trends in cancer mortality in Uruguay

    International Nuclear Information System (INIS)

    Objective: To analyze trends in cancer mortality in Uruguay in the period 1989-2008. Methodology: The National Cancer Registry (NCR) collects information from cancer mortality from the death certificates: 147 631 deaths were identified in the period from cancer, which was recorded topography, sex and age. They were calculated for each year mortality rates adjusted for age (TMAE) using as standard the world population. Trends were assessed using the method and calculated the joinpoint Estimated Annual Percent Change (ESPP). Results: The TMAE presents downward trend in both sexes (ESPP = significant -0.60 in men and -0.49 In women). In the period studied, mortality presented decreasing trend when it comes to cancer breast cancer in women (ESPP -0.79, significant), and increased for prostate cancer (ESPP = 0.70) and kidney (ESPP = 1.82 and 1.71 in men and women respectively). As regards the digestive system decreased mortality observed for esophageal cancer (ESPP in = -1.93 men and women = -1.78) and stomach (ESPP = -2.22 men and women -2.24 ). Mortality for cancer of colorectum is stable in men (ESPP = 0.35 No significant (NS)) and shows a decline slight but steady in women (ESPP -0.5). As for cancers that show strong association with smoking, decreased mortality observed lung and laryngeal cancer in men (ESPP = -1.11 and -2.05 respectively), confirming the trend found between 1990 and 2001; in women there is increased mortality from lung cancer (ESPP = 2.76) that is not accompanied by increased mortality from laryngeal cancer (-0.1 ESPP = NS). Mortality from cancers oral cavity and pharynx is stable, but in women a significant increase (ESPP = 1.84) is observed when the oral cavity is analyzed in isolation (lip, tongue, gums, palate). As cervical cancer, mortality trends in 20 years is to increase (ESPP = 1.14), however, if consider only the past decade, mortality appears stabilized (ESPP = 0.57 NS). Conclusions: The overall trend of cancer mortality (all sites

    International Nuclear Information System (INIS)

    Objective: To evaluate the incidence of TPM in Uruguay through the RNC data. Materials and Methods: Of the incident cases registered in 2008, they were selected those presented in the database prior cancer registry. The are excluded in situ of the cervix and non-melanoma skin carcinomas. Results: At the present time are entered to the the base of the RNC 11859 new cases of cancer incidents in 2008. Of these 566 (4.7%) had a prior record of criteria selection where 308 were women and 258 men. Of these, 450 met the IACR / IARC criteria (*). (Two topographies and / or different histologies). The median age of first tumor presentation was 65 years (22-89). The second 71 years (27-94). The median of the difference was about 4 years Analyzed by gender: Breast cancer (CM) was the most frequent tumor in women, cancer as first (142) and as second (85). The most common associations (excluding Bilateral) CM, CM with gynecological tumors were (TG: ovarian and corpus uteri) 11% CM and colo-rectum (CCR) (9.4%), TG and CCR (5%). 26% of female cases occurred in two hormone-dependent tumors (CM and CM bilateral or TG). In men prostate cancer (PC) is the most common tumor as first cancer (76) but the CCR is the most frequent and second (56). The association comprises CP-CCR 15% of cases and CP association and transitional tumors (TT) 10%. The association of two or more snuff-dependent tumors was observed in 8% of cases. When discriminated by sex in men is 13%, amounting to 19% if taking into account the multiple TT, while in women corresponds to 2%. Conclusions: The profile presentation of TPM in the RNC of Uruguay is similar to that reported other records in both frequency (depending on the criteria that defined) and associated type of tumors. The most frequent associations also They are similar to those observed by other authors: CCR, CM and TG women and CCR, and CP TT in men. The association of tumors are also observed with risk common factors: in women hormonal factors linked to

Its location, about ten "leguas" from the town of Humahuaca, coincides with the archaeological site academically recognized as an Inka fortress. Based on this case study we examine the continuities and discontinuities in the eastern region of Quebrada de Humahuaca, through time and territory. The concept of frontier enables us to rethink the relationship between History and Archaeology, regarding the study of the early centuries of the Spanish conquest in the region under study.

    Bovine viral diarrhea (BVD) affects bovine production and reproduction causing significant economic losses all over the world. Two viral species has been recognized: BVDV-1 and BVDV-2, both distributed worldwide. Recently, novel specie of BVDV named HoBi-like pestivirus was discovered. The presence of BVDV was confirmed in 1996 in Uruguay, however, does not exist until today a schedule of compulsory vaccination along the country. Serological studies with samples from all Uruguayan herds were performed during 2000 and 2001 demonstrating that all of them were seropositive to BVDV with a mean prevalence of 69%. In addition, there have been no new studies done since those previously described and it is important to mention that the genetic diversity of BVD has never been described in Uruguay. Nowadays, there is strongly suspect that BVDV is one of the most important causes of reproductive failures in our herds. The aim of this study was to describe for the first time in Uruguay the genetic diversity of BVDV with samples collected from different regions along the country. Serological status of 390 non-vaccinated animals against BVDV with reproductive problems from farms of Rivera, Tacuarembó and Florida departments of Uruguay were studied. All herds were seropositive to BVDV and high proportion of animals were positive (298/390), while 4.1% (16/390) of the animals were positive to Antigen Capture ELISA test and Real Time PCR. Phylogenetic analysis performed with concatenated sequences from the 5'UTR and Npro genomic regions revealed that BVDV-1 and BVDV-2 are infecting our herds, being BVDV-1 the most frequently found. The major subtype was BVDV-1a, followed by BVDV-1i and BVDV-2b. This is the first study that describes the genetic diversity of BVDV in Uruguay and it will contribute to the elaboration of sanitization programs. PMID:26597189

    The combination of temperature and atmosphere composition for storage of Pyrus communis L. 'Rocha' treated with 1-methylcyclopropene was investigated. Fruits treated with 312 nl l(-1) 1-methylcyclopropene were stored at 0 ℃ and 2.5 ℃ in air and controlled atmosphere (CA) (3.04 kPa O2+ 0.91 kPa CO2). Fruits were removed from storage after 14, 26 and 35 weeks, transferred to shelf-life at approximately 22 ℃ and assessed for ripening and quality, symptoms of superficial scald and internal browning and the accumulation of biochemical compounds related to scald after 0, 1 and 2 weeks. Superficial scald occurred only in fruits stored for 35 weeks in air at 2.5 ℃. Levels of conjugated trienols and α-farnesene increased during the first 26 weeks in storage, remaining constant thereafter. During shelf-life, conjugated trienols were higher in fruits stored in air at 2.5 ℃. Internal browning developed in shelf-life after 26 weeks at 2.5 ℃. Pears in air at 2.5 ℃ were not able to stand a 2-week shelf-life after 35 weeks of storage, while fruits stored at 0 ℃ under CA ripened slowly after the same storage period. The retention of firmness during shelf-life of 1-methylcyclopropene-treated 'Rocha' pear can be overcome by elevating the storage temperature from 0 ℃ to 2.5 ℃, but CA is a required complement to avoid excessive softening after long-term storage. The ratio carotenoid/chlorophyll increased during storage and shelf-life, as plastids senesced. CA reduced the rate of chlorophyll loss during the first 14 weeks in storage, but its effect was reduced afterwards. 'Rocha' pear treated with 1-methylcyclopropene had a similar post-harvest behaviour during long-term storage at 0 ℃ in air or at 2.5 ℃ under CA. PMID:24216324

  14. The chronology of hand stencils in European Palaeolithic rock art: implications of new U-series results from El Castillo Cave (Cantabria, Spain).

    2015-07-20

    The hand stencils of European Paleolithic art tend to be considered of pre-Magdalenian age and scholars have generally assigned them to the Gravettian period. At El Castillo Cave, application of U-series dating to calcite accretions has established a minimum age of 37,290 years for underlying red hand stencils, implying execution in the earlier part of the Aurignacian if not beforehand. Together with the series of red disks, one of which has a minimum age of 40,800 years, these motifs lie at the base of the El Castillo parietal stratigraphy. The similarity in technique and colour support the notion that both kinds of artistic manifestations are synchronic and define an initial, non-figurative phase of European cave art. However, available data indicate that hand stencils continued to be painted subsequently. Currently, the youngest, reliably dated examples fall in the Late Gravettian, approximately 27,000 years ago.

    The Urgonian limestones of El Castillo Cape (lower Albian) were deposited in a shallow platform in which developed rudist and coral constructions. A further karstification created caves at metrical scale filled by sandy deposits. The rudist assemblages consist largely on bouquets and thickets of caprotinids in whose interspaces grew bouquets of monopleurids. A complex diagenetic history occurred upon both caprotinid and monopleurid shells, from early stages (vadose meteoric dissol...

    The shallow marine carbonate platform sediments of El Castillo Cape (lower Albian, Gorliz, Bizkaia) bear rudists from the families Monopleuridae and Caprotinidae. The geochemical, isotopic and luminescent behavior of caprotinid shells allows to us to assure a different response to diagenetic processes in comparison with the monopleurid ones. A medium diagenetic degree for caprotinid shells is deduced from the constant cationic profiles, low Na+ and Sr2+ contents, high Mn2+ and Fe2...

    Alternatives are needed for long-term preservation of European pears (Pyrus communis L.) after the ban on diphenylamine. "Rocha" pear fruit harvested at commercial maturity were treated with 1-methylcyclopropene (1-methylcyclopropene, SmartFresh™) and diphenylamine and stored at 0 ℃, 90-95% relative humidity, under normal atmosphere for up to six months or under controlled atmosphere (controlled atmosphere, 3 kPa O2 + 0.7 kPa CO2) for up to 9.4 months. At 312 nl l(-1), 1-methylcyclopropene reduced softening and yellowing, and increased soluble solids content during shelf life in comparison with fruit treated with diphenylamine. 1-Methylcyclopropene at 312 nl l(-1) was also more effective than diphenylamine in reducing superficial scald and internal browning disorders. 1-Methylcyclopropene at 150 nl l(-1) had little effect on ripening-related changes but was effective against physiological disorders of pears stored in regular atmosphere or under controlled atmosphere. Delayed controlled atmosphere slightly reduced internal browning disorders but increased superficial scald. 1-Methylcyclopropene at 312 nl l(-1) reduced physiological disorders in "Rocha" pear under refrigerated storage and delayed ripening-related softening and color changes during shelf life. At 150 nl l(-1), 1-methylcyclopropene is as effective as diphenylamine against storage disorders without ripening impairment. PMID:26437671

    My first contact with the IAEA was in 1989 in Moscow, at ATOMINFORM while attending the International Centre for Scientific and Technical Information (ICSTI) training: INIS Human Resources: On the Job Group Training for Developing INIS Member States. Lectures were given about FIBRE data entry software and searches on INIS CD-ROM. Through the Regional Cooperation Agreement for the Promotion of Nuclear Science and Technology in Latin America and the Caribbean, specifically by the ARCAL X project, modern technologies for access to information were introduced and the creation of INIS Centres was supported. During its execution, from 1985–1992, many countries in the region became members of INIS, including our country, Uruguay. Our involvement in the RLA/0/017 ARCAL XLII Regional Network for Nuclear Information increased after our application for INIS Liaison Officer was submitted by government authorities in Uruguay. This enabled better conditions for the formation of a nuclear Regional Information Network with 15 countries in Latin America

    Paenibacillus larvae is the causative agent of American Foulbrood (AFB), a deleterious disease that affects honeybees. In Uruguay it was first reported in 1999. In 2001 the bacterium was spread all over the country, and its prevalence in honey was estimated in 51%. Two P. larvae genotypes were found; ERIC I - BOX A, worldwide distributed and ERIC I - BOX C, exclusively detected in Argentina until then. In the present manuscript we analyzed the evolution of AFB outbreaks from 1999 to 2009, presented a new nation-wide survey carried out during 2011 when a prevalence of 2% was found and discuss national strategies for prevention of the disease. Since Uruguay is a small country where almost all beekeepers are registered, Uruguayan experience can be useful to be applied in other countries. PMID:22381478

  11. Groundwater resources in Uruguay: Importance and present use

    International Nuclear Information System (INIS)

    Traditionally the use of the water resources in Uruguay was based on the exploitation of surface waters due to the great density of the hydrographic network. The intensive use of the groundwater resources began after 1950, mainly for supplying small towns the country, nowadays this practice covers the 70% of the country. Basically, this evolution was a consequence of the lower cost of the groundwater, its availability and good quality. Since 1980 the use of the groundwater has been intensified even more, mainly with the purpose of satisfying different demands like vegetable plantation irrigation either in the open air or in the entrance of cholera to the country during the 1990 decade trough a program for supplying water to small communities in the frontier area. In addition, it is marked out the use of thermal and flowing aquifers belonging to the Guarani Aquifer System as water suppliers for thermal spas and hotels in a reduced area, eventhough having a great hydric potencial whose exploitation yields one of the major foreing currency entrance because of regional tourism. Moreover, it can be stated that Uruguay do not present an important groundwater weath because of regional tourism. Moreover, it can be stated that Uruguay do not present an important groundwater weath because the 65% of its aquifers are fisurated and the others are pourous with diverse potentiality.

    Full Text Available A magnetita (Fe3O4 é um óxido magnético de ferro natural formado por íons Fe+2 e Fe+3. É o mais comum mineral fortemente magnético, estando presente em pequenas quantidades em quase todas as rochas e também nos meteoritos. A nanotecnologia está largamente presente em todo nosso dia a dia. É possível encontrar diferentes aplicações nas mais diversas áreas da indústria: Eletroeletrônicos, metalurgia, cerâmicos, tintas, tecidos, indústria de polímeros, medicina entre outras. Atualmente a Anglo American Fosfatos do Brasil não produz magnetita, mas possui uma produção de rejeito de 2 Mt (milhões toneladas com teores de magnetita por volta de 40%, na granulometria de 2 mm, sendo esse material enviado integralmente para a barragem de rejeito. O aproveitamento desse material, dada uma recuperação de 60%, traria um crescimento de 78,5 milhões de dólares no PIB do estado. A maior parte da produção de ferro do Brasil é feita por flotação, sendo que tal tipo de produção prejudica a utilização da magnetita, especificamente, para a produção de ferrofluidos nanomagnéticos, devido a enorme quantidade de produtos químicos, principalmente surfactantes, envolvidos na etapa de flotação. Contudo o objetivo desse trabalho é obter um concentrado de magnetita proveniente do rejeito da produção de rocha fosfática por jigagem, para que a mesma possa ser usada na produção de ferrofluidos. Os resultados da utilização do jigue como separador dos minerais são satisfatórios na produção de magnetita para ferrofluidos como coproduto da produção de concentrado de rocha fosfática.

  18. SIT in Uruguay: Screwworm Eradication and the Need for Integration for a Successful Pest Management Program

    International Nuclear Information System (INIS)

    The Nuclear Research Center at the School of Sciences is the unique nuclear facility constructed and devoted to work with radiation and isotopes in Uruguay. SIT technology experience was gained working with the Chagas' disease vector, Triatoma rubrovaria, as a model (Cristina et al., 1986; Salvatella et al., 1987; Cristina et al., 1985, 1984a,b,c). At the present time, working together with the Ministry for Cattle, Agriculture and Fisheries, it was possible to determine the importance of New World Screwworm control and/or eradication from Uruguay. This pest challenges the main export products of Uruguay. Regarding myiasis, four different species of Diptera have been found in Uruguay: Chlochliomyia hominivorax, Chlochliomyia macellaria, Chrysomya albiceps and Dermatobia hominis. C. hominivorax accounts for 87.2 % of all myiasis in Uruguay. The general prevalence of the disease is 4.5% of bovines and 6.2% of ovines are affected. The death rate of affected animals is calculated to be 6.5% for bovines and 18.5% for ovines. Considering a population of 10 million cattle and 26 million ovine in Uruguay, 450,000 bovines and 1,612,000 ovines are affected each year. Total loses are estimated to be US$24 million per year. Since no geographical barrier separates Uruguay from Brazil, integrated management is the only choice to successfully control this important pest. SIT against screwworm would be very beneficial for Uruguay.

  19. An electric charge has no screw sense--a comment on the twistfree formulation of electrodynamics by da Rocha & Rodrigues

    CERN Document Server

    Itin, Yakov; Hehl, Friedrich W

    2009-01-01

    Da Rocha and Rodigues (RR) claim (i) that in classical electrodynamics in vector calculus the distinction between polar and axial vectors and in exterior calculus between twisted and untwisted forms is inappropriate and superfluous, and (ii) that they can derive the Lorentz force equation from Maxwell's equations. As to (i), we point out that the distinction of polar/axial and twisted/untwisted derives from the property of the electric charge of being a pure scalar, that is, not carrying any screw sense. Therefore, the mentioned distinctions are necessary ingredients in any fundamental theory of electrodynamics. If one restricted the allowed coordinate transformations to those with positive Jacobian determinants (or prescribed an equivalent constraint), then the RR scheme could be accommodated; however, such a restriction is illegal since electrodynamics is, in fact, also covariant under transformations with negative Jacobians. As to (ii), the "derivation" of the Lorentz force from Maxwell's equations, we poi...

  20. Reply to da Rocha and Rodrigues' comments on the orientation congruent algebra and twisted forms in electrodynamics

    Energy Technology Data Exchange (ETDEWEB)

    Demers, D.G. [Everybody Reads Independent Bookstore, Lansing, MI (United States)

    2010-07-15

    The recent claim by da Rocha and Rodrigues that the nonassociative orientation congruent algebra (OC algebra) and native Clifford algebra are incompatible with the Clifford bundle approach is false. The new native Clifford bundle approach, in fact, subsumes the ordinary Clifford bundle one. Associativity is an unnecessarily too strong a requirement for physical applications. Consequently, we obtain a new principle of nonassociative irrelevance for physically meaningful formulas. In addition, the adoption of formalisms that respect the native representation of twisted (or odd) objects and physical quantities is required for the advancement of mathematics, physics, and engineering because they allow equations to be written in sign-invariant form. This perspective simplifies the analysis of, resolves questions about, and ends needless controversies over the signs, orientations, and parities of physical quantities.

    This article attempts to present the geological characteristics and tectonic and sedimentary evolution of Uruguayan basins and the extent to which they have been explored. Uruguay is on the Atlantic coast of South America. The country covers about 318,000 sq km, including offshore and onshore territories corresponding to more than 65% of the various sedimentary basins. Four basins underlie the country: the Norte basin, the Santa Lucia basin, the offshore Punta del Este basin, and the offshore-onshore Pelotas-Merin basin. The Norte basin is a Paleozoic basin while the others are Mesozoic basins. Each basin has been explored to a different extent, as this paper explains.

Se infiere que sus movimientos eoceno-oligocenos estuvieron dominados por 'stresses' transpresivos con transcurrencia sinistral. Esta inferencia surge del estudio de estructuras S-C en rocas de falla, y en la vergencia de un pliegue de arrastre, directamente observados sobre la traza de la falla.

Se determinaron las direcciones y sentidos del transporte tectónico sobre la base de la cinemática de fallas inversas y la intersección de éstas con el clivaje. Se deduce una rotación de 65° en el sentido horario de la dirección de acortamiento, desde un rumbo oeste hasta uno nor-noroeste. Por otro lado, se consideró la alternativa que las rocas hayan rotado en sentido antihorario, conservándose constante la dirección de acortamientoNew kinematic data from the Sierra Castillo Fault at Quebrada del Carrizo, Precordillera of Atacama Region, Chile. The Sierra Castillo Fault and its associated mesoscopic structures were studied at Quebrada del Carrizo. Here the fault juxtaposes Triassic and Paleozoic rocks on the east with Bajocian rocks on the west. The Sierra Castillo Fault serves as a master fault of its associated mesoscopic structures.

  8. Aging and cancer in Uruguay: epidemiology and health screenings

    International Nuclear Information System (INIS)

    According to estimates by the UICC 2020 the annual number of new cases cancer worldwide will reach 20 million, of which 14 occur in developing countries, which must address the problem with little human and material resources. This increase, in particular the care burden will weigh in countries development, is the result, among other factors, the transition patterns epidemiological, accompanied by an increase in life expectancy at birth. This determines the prevalence of chronic and degenerative diseases within which highlights the cardiovascular and oncological diseases. In Uruguay, the life expectancy at birth has increased from 45 in 1900-75 to end of the century. In parallel we are witnessing a progressive aging of the population, with an increasing proportion of older age groups. taking population aged 65 or more, it represented 4.5% in 1908 and reached 21.2% in 2000 Similarly, cancer mortality has increased percentage, in 2001 representing 23.8% of total deaths. Depending on age, analyzed the increased risk of developing or dying from cancer in Uruguay and its impact is weighted mortality of seven locations more frequent. For each of these locations the percentage of deaths in the population of 65 or more years is as follows: lung 60.9%, breast 60.3%, prostate 91.4%, colorecto 78.3%, 72.3% stomach, esophagus 70.3%, 72.2% pancreas, averaging 69.4% overall.

  9. Bio fuels and family farming in Uruguay: A feasible alliance?

    International Nuclear Information System (INIS)

    The global energy crisis caused by high levels of fossil fuels consumption and the signs of oil depletion explain the search for alternative energy to traditional sources. Progress towards bio-fuels policy is positioned in a central place in Uruguay s political agenda. This context converges with a scenario of expansion of agricultural activity, marked by a dynamism based on the domestic economic environment changes, and major transformations in the productive base. In this context, in order to assess the social impacts resulting from the expansion of crops for energy purposes, this research was carried out. It explores the social impact of bio fuels production in Uruguay taking as a reference the situation of family farm production. It assumes that the demand of land for energy crop production puts pressure on other production systems. Related to this, it is possible to establish a continuum between a view that holds that family farms are marginal to bio fuel production, and an inclusive view which encourages the incorporation of family farmers into national production chains. In this scenario, the paper attempts to provide elements to answer the question about whether this new line of national production generates opportunities or threats to family farming

La elasticidad es mayor para los jóvenes, las mujeres y los menos educados. Los resultados indican que la elasticidad crece ante choques macroeconómicos adversos. Además, al desagregar por ocupación o formalidad e informalidad, los resultados sugieren que un aumento del desempleo produce un aumento de la informalidad y del cuentapropismo que lleva a una caída de los ingresos en estos sectores, que actúan como “amortiguador”.

Uma vez que o desgaste do revestimento não é uniforme, foi realizado o acompanhamento do desgaste do revestimento interno do moinho de bolas (SAG 4,87 x 6,09 m da empresa Vale Fertilizantes S.A. Unidade Catalão-GO. Tal moinho trabalha com rocha fosfática e o monitoramento se deu através de um dispositivo prático visando à determinação do comportamento do desgaste do revestimento ao longo de toda a extensão do moinho, desde a alimentação até a descarga, bem como a variação em um único perfil de uma placa do revestimento. Observou-se que o desgaste não é uniforme tanto ao longo do moinho quanto em um mesmo perfil, indicando que o maior desgaste ocorre nos primeiros e últimos 1,5 metros, com valores muito próximos. Na alimentação do moinho o desgaste específico foi de 0,60 g/t, na descarga de 0,63 g/t e no do centro do moinho de aproximadamente 0,55g/t.

    Full Text Available Este artículo analiza la trayectoria de la lucha por la tierra en Bella Unión, una región característica en Uruguay por la producción de caña de azúcar, a través de los movimientos de clase de sus principales protagonistas: los cortadores de caña sindicalizados en la Unión de Trabajadores Azucareros de Artigas (UTAA. El recorrido histórico hace énfasis en dos períodos históricos diferentes: 1961-1973 y 2005-presente. El primero va desde la fundación del sindicato hasta el golpe militar. Se da en un contexto de auge de la lucha de masas en Uruguay en el cual los trabajadores rurales se organizan en la UTAA levantando, entre otras, la bandera de la Reforma Agraria. El segundo período está marcado por la llegada al gobierno nacional del Frente Amplio, una coalición social-demócrata que reactiva la producción de caña de azúcar en Bella Unión. Este cambio supone una oportunidad para las luchas sociales que la UTAA aprovecha con ocupaciones de tierra favoreciendo un proceso de colonización para los trabajadores rurales. Sin embargo el acceso a la tierra genera nuevas contradicciones, y por tanto nuevos desafíos, por los cambios en la forma de subsunción del trabajo al capital.

  12. Groundwater arsenic content in Raigon Aquifer System (San Jose, Uruguay)

    International Nuclear Information System (INIS)

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

    Full Text Available This paper extends the study of party organization and legislative voting to factionalize party systems. After developing a typology of factional types, it argues that hierarchically organized factions respond to a competing incentive system. Factions have interests that push them to work together for the good of the party, but at the same time, they have interests in distinguishing themselves for electoral purposes. Further, the electoral cycle drives the weights of these competing pressures, leading factional cooperation to break down as elections near. These patterns and incentives are particularly evident in Uruguay, and the paper uses roll-call data from that country's legislature to test the propositionsEl presente artículo aplica el estudio de la organización de partidos y el voto legislativo a sistemas de partidos con facciones. Tras desarrollar una clasificación de los diferentes tipos de facciones, se argumenta que las facciones jerárquicamente organizadas responden a un sistema competitivo de incentivos. Pese a que las facciones tienen intereses que las empujan a trabajar juntas por el bien del partido, al mismo tiempo, tienen interés en diferenciarse unas de otras por propósitos electorales. Además, el ciclo electoral dirige los pesos de estas presiones competitivas provocando la ruptura en la cooperación entre las facciones conforme se aproximan las elecciones. Estas pautas e incentivos son particularmente evidentes en el caso de Uruguay, por lo que el artículo utiliza datos del voto nominal del Legislativo del país para probar estos argumentos.

Es por todos recordada la expulsión, de todos aquellos judíos que no quisieron convertirse al cristianismo, operada en la España de los Reyes Católicos, en 1492. Este tipo de hechos se han ido repitiendo a lo largo de la historia hasta el ascenso del nazismo al poder en Alemania en 1933, pasando por los brotes de antisemitismo operados en la Europa de la segunda mitad del siglo XIX. Debido a ello, muchos judíos tomaron la decisión de marcharse y buscar destinos más tolerantes para rehacer sus vidas, como fue el caso de Uruguay.

    After 25 years without any reported cases of rabies in Uruguay, the northern region of the country experienced an epizootic of bovine paralytic rabies in October 2007. The outbreak affected bovines and equines, and the main source of infection was the bat Desmodus rotundus, the only hematophagous species in the country. From October 2007 to July 2008, 42 bovine, 3 equine and 120 chiropteran samples were submitted to the National Veterinary Diagnostic Laboratory for rabies testing. A total of 12 samples (7 bovine, 2 equine and 3 from D. rotundus) were positive by the fluorescent antibody test, and viruses were isolated by the mouse inoculation test. The objective of this study was to compare the antigenic and genetic characteristics of these isolates and three isolates from insectivorous bats from other regions. Antigenic typing using a panel of eight monoclonal antibodies identified all 12 viruses as variant 3 (AgV3), a variant associated with D. rotundus. Two isolates from insectivorous bats (Tadarida brasiliensis and Molossus sp.) were characterized as antigenic variant 4 (AgV4) while the third, from Myotis sp., could not be characterized using this panel as its reactivity pattern did not match that of any of the known antigenic variants. Partial N-gene sequences (nt 149-1420) of these isolates were aligned with homologous sequences derived from GenBank by the CLUSTAL/W method and used to build a neighbor-joining distance tree with the Kimura 2-parameter model. All 12 isolates were genetically grouped into the D. rotundus cluster as they shared 100% identity. In the phylogenetic analysis, the three isolates from insectivorous bats segregated into three clusters: one related to T. brasiliensis, one to Myotis sp. and the other to Lasiurus sp., although the isolate associated with the latter came from a Molossus sp. specimen. These results indicate that AgV3 was associated with the outbreak of bovine paralytic rabies in Uruguay. This is the first report of rabies

    2016-01-01

    Background: The Atlantic Forest is globally one of the priority ecoregions for biodiversity conservation. In Argentina, it is represented by the Paranense Forest, which covers a vast area of Misiones Province between the Paraná and Uruguay rivers. The Uruguay River is a global hotspot of freshwater gastropod diversity, here mainly represented by Tateidae (genus Potamolithus) and to a lesser extent Chilinidae. The family Chilinidae (Gastropoda, Hygrophila) includes 21 species currently recorded in Argentina, and three species in the Uruguay River. The species of Chilinidae occur in quite different types of habitats, but generally in clean oxygenated water recording variable temperature ranges. Highly oxygenated freshwater environments (waterfalls and rapids) are the most vulnerable continental environments. We provide here novel information on three new species of Chilinidae from environments containing waterfalls and rapids in the Uruguay River malacological province of Argentina. Materials and Methods: The specimens were collected in 2010. We analyzed shell, radula, and nervous and reproductive systems, and determined the molecular genetics. The genetic distance was calculated for two mitochondrial markers (cytochrome c oxidase subunit I–COI- and cytochrome b -Cyt b-) for these three new species and the species recorded from the Misionerean, Uruguay River and Lower Paraná-Río de la Plata malacological provinces. In addition, the COI data were analyzed phylogenetically by the neighbor-joining and Bayesian inference techniques. Results: The species described here are different in terms of shell, radula and nervous and reproductive systems, mostly based on the sculpture of the penis sheath. Phylogenetic analyses grouped the three new species with those present in the Lower Paraná-Río de la Plata and Uruguay River malacological provinces. Discussion: Phylogenetic analyses confirm the separation between the Uruguay River and the Misionerean malacological

    International Nuclear Information System (INIS)

    In Uruguay, breast cancer incidence is 76.41 per 100.000, and death rate is 25.22 per 100.000. Since 1998, there is a National Programme of breast cancer early detection for females over forty years of age. We studied the state of the mammography facilities throughout the country. There are 657.000 female over forty and 51 mammography X-ray equipment. The Programme includes 2 mammography X-ray equipment in mobile units in the capital and 18 in hospitals all around the country. There are taken 120.000 mammographic exams per year, 15.000 of them belong to women who had participated in the Programme. We found that no mammography facility has established Quality Assurance Programmes. Despite the results of this study showed that is suitable the number and age of the mammography X-ray equipment, the lack of Quality Assurance Programmes will produce, in a short time, a negative cost-benefit balance. The consequences will be serious social, human an economical damages. (author)

    Participatory research in which experts and non-experts are co-researchers in addressing local concerns (also known as participatory action research or community-based research) can be a valuable approach for dealing with the uncertainty of social-ecological systems because it fosters learning among stakeholders and co-production of knowledge. Despite its increased application in the context of natural resources and environmental management, evaluation of participatory research has received little attention. The objectives of this research were to define criteria to evaluate participatory research processes and outcomes, from the literature on participation evaluation, and to apply them in a case study in an artisanal fishery in coastal Uruguay. Process evaluation criteria (e.g., problem to be addressed of key interest to local and additional stakeholders; involvement of interested stakeholder groups in every research stage; collective decision making through deliberation; and adaptability through iterative cycles) should be considered as conditions to promote empowering participatory research. Our research contributes to knowledge on evaluation of participatory research, while also providing evidence of the positive outcomes of this approach, such as co-production of knowledge, learning, strengthened social networks, and conflict resolution.

    Full Text Available The influence of insecticides commonly used for agricultural purposes on beehive depopulation in Uruguay was investigated. Honeycombs, bees, honey and propolis from depopulated hives were analyzed for pesticide residues, whereas from active beehives only honey and propolis were evaluated. A total of 37 samples were analyzed, representing 14,800 beehives. In depopulated beehives only imidacloprid and fipronil were detected and in active beehives endosulfan, coumaphos, cypermethrin, ethion and chlorpyrifos were found. Coumaphos was present in the highest concentrations, around 1,000 µg/kg, in all the propolis samples from active beehives. Regarding depopulated beehives, the mean levels of imidacloprid found in honeycomb (377 µg/kg, Standard Deviation: 118 and propolis (60 µg/kg, Standard Deviation: 57 are higher than those described to produce bee disorientation and fipronil levels detected in bees (150 and 170 µg/kg are toxic per se. The other insecticides found can affect the global fitness of the bees causing weakness and a decrease in their overall productivity. These preliminary results suggest that bees exposed to pesticides or its residues can lead them in different ways to the beehive.

  6. Stratigraphy, palaeontology and age of the Las Ventanas Formation, Uruguay

    International Nuclear Information System (INIS)

    The stratigraphy, palaeontology and age of the Las Ventanas Formation (FmLV) is here analyzed. Its type area represents a large syncline (Cerro Las Ventanas Syncline) with an axis plounging 35 grades to the S20W. The lithostratigraphy of the FmLV is described, and separated into the following informal units: basic volcanics and breccias, polymictic conglomerates, sandstones and conglomerates, and laminated pelites. The Formation represents a thinning- and fining-upward sequence, recording evolution from an alluvial fan-dominated environment to shallow marine conditions with occasional storms. Sedimentary structures and petrography of conglomerates and sandstones point to a steep palaeorelief. A number of organic-walled microfossils is described for the first time, namely: Leiosphaeridia tenuissima, L. minutissima, Lophosphaeridium sp., Soldadophycus bossii, S. major, Soldadophycus sp., Vendotaenia sp. and psilate, branched filaments. The assemblage is characterized by its low diversity, abundance and large size (up to 400 μm) of Leiosphaeridia. Wrinkle structures occur in the laminated pelite unit. Based on the microfossils we assign the FmLV to the lower Vendian (Varangerian, ca. 600 Ma). The Playa Hermosa Formation can be interpreted as a lateral facies of the FmLV, or be alternatively- younger than the latter unit. On the basis of microfossil assemblages, we envisage that the FmLV immediately predates the Arroyo del Soldado Group. An extensional geotectonic setting, possibly a rift, is postulated for FmLV. This is a contribution to project IGCP 478. Keywords: Neoproterozoic, Vendian, Varangerian, Uruguay, acritarchs

  8. Summer crops evapotranspiration for two climatically constrating regions of Uruguay

    International Nuclear Information System (INIS)

    During the growth and development of grain crops there are a series of limiting factors which prevent obtaining yields to full potential. In particular, in summer crops grown in rain fed conditions, water deficiency stands out as one of the main factors affecting yield productivity. In this study crop evapotranspiration (E Tc) was estimated as a way to assess water needs in summer crops and real evapotranspiration (E Tr) of rain fed crops that occurs under field conditions. The study consisted in estimating E Tc and E Tr of soybean G M IV and V I, corn, sorghum and sunflower in two contrasting climatic regions of Uruguay for a period of 24 years (1984/2007) using the model WinISAREG. Water needs varied. The Nina and Nino years stood out with higher and lower values of Etc respectively. Such water needs are linked to cycle duration. Daily Etc was higher in the North and total Etc was higher in the South. The Etr obtained was substantially lower than Etc and with higher variability in most agr o-climatic situations studied. Sunflower and sorghum were the crops that presented the least differences between Etc and E Tr, and soybean and corn showed the greatest differences at both locations

    Full Text Available Uruguay es uno de los países sudamericanos con una proporción significativa de su población viviendo en el exterior. Desde los años setenta, el país ha tenido una emigración neta. Aunque esta tendencia se debilitó a principios de los noventa, recobró fuerza con la llegada de una severa crisis económica en 1999. En este artículo se discuten las características de la migración reciente de uruguayos y se pone en evidencia la relación entre crisis económica y emigración. El volumen del flujo poblacional en 2002 es comparable con las olas de migración que tuvieron lugar en los setenta. Los emigrantes con educación universitaria están sobrerrepresentados en comparación con la población general. Existe una correlación entre el acceso a redes de emigrantes uruguayos en los países de destino y la probabilidad de que un hogar haya tenido un miembro que emigró en 2002.

  10. Radiation Protection Education in Diagnostic Radiology in Uruguay

    International Nuclear Information System (INIS)

    In Uruguay the lack of Radiation Protection (RP) laws makes education in medical use of ionizing radiations at University, a decisive factor of changes. The six years experience in teaching technicians, radiologists, interventional cardiologists and anesthetists in curricular lectures, continuing education courses and workshops, show the importance of a close link between educators and occupationally exposed professionals. Regarding training and education in the optimization of the procedures, it is essential that both teacher and student comprehend the exact meaning of ALARA concept. This implies that although the educator is the one who manages the physical basis of RP, the student is who teaches the educator about the procedures. This turns RP education into a dynamic process in which at the same time, both educator and student learn and teach. After the theoretical lectures, it is essential that students show their ability in applying the acquired knowledge in their everyday practice. Last nut not least, in order to fulfill the first RP principle,all medicine students need to be educated in RP and quality image criteria before the get their medical doctor degree. Our experience shows that RP education in diagnostic radiology requires an expert with both medical physics and Image technology knowledge that allow an approach to students work, language and everyday problems. Despite the fact that the main result of the Education Program is the way professionals improve their practice, another consequence was that the Regulatory Authority of the country called the teacher team to coordinate the first RP national course.

  11. Effective and independent regulatory national infrastructure: Uruguay case

    International Nuclear Information System (INIS)

    Since inception in 1986 the National Direction of Nuclear Technology has fulfilled with the assignment known as 'Control of the ionizing radioactivity in its medical and industrial applications'. This strategic task as far as safety, was performed with significant and crucial deficiencies which they even motivated the users to question the reliability of the institution. The deficiencies were mainly as follows: 1) absence of a regulatory frame; 2) insufficient qualification of technical human resources and 3) lack of suitable equipment. From the use for Uruguay of the Model Project and the beginning of a new management of Dinaten (October 2000), a sensible and well-known increase in the quality and efficiency of the regulating function in the country, which we can summarize in the following landmarks: regulatory frame with the use of a basic norm and eight regulating norms according to the main practices that are developed in the country; intensive training of the regulatory body staff; permanent accomplished update of the inventory of sources; beginning of licensing activities; equipment of last generation; regulation of the personal dosimetry services and management of radioactive waste and establishment of a National Program of Radiological Emergencies.

  12. Micro and mini hydroelectric power assessment in Uruguay

    International Nuclear Information System (INIS)

    The School of Engineering in Montevideo, Uruguay, within the framework of Agreements made with the National Utility, has carried out an assessment of the potential and studies of the feasibility of the use of renewable energy for the generation of electrical power, both at the industrial level and the autonomous level for rural electrification. Original assessment methodologies were developed, including calculation tools which allow, for example, to analyze historical meteorological data, to calculate the available energy in different kinds of energy generators and also to stimulate the operation and design of autonomous systems with established load requirements and service quality. At the micro and mini hydropower assessment, the main role was placed on the census of potential users and the preliminary analysis of the representative places for the different technical solutions adequate to the variety of topographic conditions and load requirements. For power above 1 MW and up to 5 MW, the generating potential was assessed all over the country. If power lower than 1 MW or lower than 100kW (mini and micro) is considered, the information available in maps with contour lines, including in those of a 1:50,000 scale, is not enough to identify the most adequate places. Instead, knowledge of the place is indispensable in these cases. A preliminary plan of several installations was worked out. (Author)

In the accomplishment of the nuclear option, next stage to take into account is the comparison of the following: a) 300/600 Mw Nuclear Power station owned by Uruguay; b) 600/1200 Mw Nuclear Power station shared amongst Uruguay and neighboring countries. National energy needs were studied, including previous electric demand studies made by international consultants. National direct resources and support infrastructure were also analysed. Oil, gas, coal and hydraulic options were compared to the nuclear option

    The World Health Organization's Framework Convention on Tobacco Control (FCTC) is the first international public health treaty to address the global spread of tobacco products. Ethnographic research at the fourth meeting of the FCTC's Conference of the Parties in Uruguay highlights the role of the FCTC in recalibrating the relationship between international trade and investment agreements and those of global public health. Specifically, we chart the origins and development of the Punta del Este Declaration, tabled by Uruguay at the conference, to counter a legal request by Philip Morris International, the world's largest tobacco transnational, for arbitration by the International Centre for the Settlement of Investment Disputes over Uruguay's alleged violations of several international trade and investment treaties. We argue that medical anthropologists should give greater consideration to global health governance and diplomacy as a potential counterweight to the 'politics of resignation' associated with corporate capitalism.

    Full Text Available Populations of Caiman latirostris are known to occur in Uruguay but their geographic distribution remains uncertain. This work presents anupdate of the species distribution and conservation status in Uruguay. Surveys conducted by the authors confirmed the presence of this species in the previously known distribution range of northwestern Uruguay, where it seems to be widespread and relatively abundant in contrast to earlier reports. We report new localities for C. latirostris, most relevant being those of the Cebollatí and Tacuarí Rivers, and the Pelotas, India Muerta and San Miguel stream basins, which significantly expand its distribution through important wetlands in the eastern part of the country. The overall distribution is coincident with different landscape types, where lagoons, artificial impoundments, livestock waterholes, rivers, streams, creeks and marshes are inhabited by caiman. Illegal non-commercial hunting was detected all over the country.

    Full Text Available The medieval Alcázar (fortress of Madrid was transformed into the residential palace of the Austrian dynasty in Spain from the reign of Charles I through that of Charles II. On Christmas Eve 1734, during the reign of the Bourbon king Philip V, the palace suffered a devastating fire, resulting in the construction of a new Royal palace, already baroque, on the same site. This research reconstructs the history – until now fragmented – of this lost medieval castle, contributing new source materials concerning the successive interventions carried out on the building. Specifically, this investigation focuses on the improvements realized during the period of the Catholic Monarchs and the first works commissioned by Charles V, prior to the definitive royal bond of 1536. This document marks the beginning of a new chapter in the constructive history of the building, when the old castle was transformed definitively into a residential palace, while highlighting the symbolic value of the Sala Rica and the rooms of protocol constructed during the Trastámara period.El alcázar medieval de Madrid se convirtió en la gran residencia de los Austrias desde la llegada de Carlos I al reinado de Carlos II. En la Nochebuena de 1734, reinando ya Felipe V de Borbón, el palacio sufrió un devastador incendio, resultado del cual se inicia la construcción del nuevo Palacio Real, ya barroco, sobre su solar. En esta investigación nos ocupamos de reconstruir la historia –hasta ahora fragmentada– de ese castillo medieval, aportando nuevos datos documentales acerca de las sucesivas intervenciones sufridas en el edificio. Nos centramos de forma especial en las obras realizadas en el período de los Reyes Católicos y en las primeras encargadas por Carlos V, antes de la definitiva real cédula de 1536 que marca el comienzo de un nuevo capítulo en la historia constructiva del edificio al transformarse de manera definitiva el viejo castillo en un palacio residencial

    The Global Threat Reduction Initiative's (GTRI) Offsite Source Recovery Project (OSRP) began recovering excess and unwanted radioactive sealed sources (sources) in 1999. As of February 2012, the project had recovered over 30,000 sources totaling over 820,000 Ci. OSRP grew out of early efforts at Los Alamos National Laboratory (LANL) to recover disused excess Plutonium- 239 (Pu-239) sources that were distributed in the 1960's and 1970's under the Atoms for Peace Program. Source recovery was initially considered a waste management activity. However, after the 9/11 terrorist attacks, the interagency community began to recognize that excess and unwanted radioactive sealed sources pose a national security threat, particularly those that lack a disposition path. After OSRP's transfer to the U.S. National Nuclear Security Administration (NNSA) to be part of GTRI, its mission was expanded to include all disused sealed sources that might require national security consideration. Recognizing the transnational threat posed by porous borders and the ubiquitous nature of sources, GTRI/OSRP repatriates U.S. origin sources based on threat reduction prioritization criteria. For example, several recent challenging source repatriation missions have been conducted by GTRI/OSRP in South America. These include the repatriation of a significant amount of Cs-137 and other isotopes from Brazil; re-packaging of conditioned Ra-226 sources in Ecuador for future repatriation; and, multilateral cooperation in the consolidation and export of Canadian, US, and Indian Co-60/Cs-137 sources from Uruguay. In addition, cooperation with regulators and private source owners in other countries presents opportunities for GTRI/OSRP to exchange best practices for managing disused sources. These positive experiences often result in long-term cooperation and information sharing with key foreign counterparts.

    Full Text Available RESUMEN: En este artículo se argumenta que el muy bajo desempeño económico de Uruguay durante el siglo XX y en particular desde la década de 1960, que lo aleja progresivamente de la dinámica de la economía mundial aumentando la brecha de subdesarrollo, se explica fundamentalmente por la especialización del país en productos de muy escasa dinámica en el mercado mundial así como de muy bajo dinamismo tecnológico. El ensayo de modelo (neoliberal en lo económico y conservador en lo político resultó un fracaso en términos de mejorar la tasa de crecimiento de largo plazo del país, profundizando su especialización basada en productos primarios. Esto implica además un problema en términos de la capacidad de generación de empleos y de la distribución de ingresos. La reactivación reciente así como algunas medidas adoptadas por el nuevo Gobierno Progresista han resultado exitosas en aumentar los salarios, reducir la informalidad y ordenar la macroeconomía luego de la profunda crisis financiera que explotó en el 2002. Pero la ruptura con el pasado, necesaria para elevar significativamente la tasa de crecimiento sostenible de esta economía, requerirá posiblemente de otras acciones en torno a una estrategia de desarrollo de largo plazo, que ponga sus miras en mejorar la capacidad innovadora de la estructura productiva desarrollando nuevas ramas mediante la integración regional.ABSTRACT: This article shows that Uruguay’s very low long term growth performance, which implies an increasing divergence with respect to the world economy, is explained by specialization and productive problems.

    Full Text Available This article analyzed the demand for meats at household level over the past decade in Uruguay, a country that exhibits a very high per capita consumption of these products. In particular, the consumption of beef is one of the highest in the world and only comparable to Argentina. The analysis involved a two-step estimation of an incomplete system of censored demand equations using household data from the last available national income and expenditure survey (2005/06. Thirteen meat products were included in the analysis: six broad beef products (deboned hindquarter cuts, bone-in hindquarter cuts, ground beef, rib plate, bone-in forequarter cuts, and other beef cuts, four products from other meats (sheep, pork, poultry, and fish, and three generic mixed-meat products. A complete set of short-term income, own-price and cross-price elasticities were computed and reported along with their 90% confidence intervals (CI. The results were consistent with both economic theory and empirical evidence as well as with the expected behavior, considering the relevance of these products, particularly beef, in the diet of Uruguayan consumers. All meat items were necessary goods and evidenced income-inelastic responses, which was expected given their high consumption level. All meats behaved as normal goods although exhibiting different reactions to changes in price. In general, beef cuts were more price elastic than other more broadly defined products. The more specific and disaggregated the meat product the higher its corresponding direct price elasticity. The complement/substitute relationships found in this study were highly depended on the specific product combinations.

  8. Geochemical and microbiological study in soils of southern Uruguay

    International Nuclear Information System (INIS)

    The sulphate reducing bacteria (S RB) constitute a diverse group of anaerobic prokaryotes that carry out the dissimilarity sulphate reduction of sulphur compounds like sulphate, sulphite, tio sulphate, and sulphide to hydrogen sulphide. Although B SR are anaerobic, some genre tolerate oxygen and some others, at low concentrations, can res pirate Fe+ 3 or oxygen, using hydrogen as electron donor. Several industries, including oil and natural gas processing and transporting plants, have been affected by their metabolic activity and the fundamental cause is the production of H S, corrosive and toxic. It damages the pumping equipment, tanks, and 2 pipes. On the other hand, the generated sulphide affects human health and causes security and environmental problems producing severe economic losses. Given the ecological and economic importance of the S RB this study attempts of its presence in soils of different characteristics from southern Uruguay. Although in the last years its knowledge at molecular level has been increased, there is still lack of information so as to be able to control all the effects produced by its metabolic activity. The objective of our work is to determine the degree of diversity of these bacteria in our soils and to know the bio corrosion potential of them. As a first step we have collected soil samples with different characteristics, having determined its p H, humidity, content of chloride and sulphates as well as the presence of S RB. Although the main obstacle to understand its ecology and diversity is the incapacity to cultivate many of the microorganisms that come from environmental samples, this difficulty can directly be avoided by means of the use of molecular techniques that allow the study of the microorganisms present or their genes. In this work we correlate the detection of sulphate reducing bacteria by classic and molecular methods in the different soils studied

The largest nutritional problems occurring globally are protein-energy malnutrition, Ca, Fe, I, Zn and vitamin A deficiencies. Being rice the staple food more consumed worldwide, outstanding care is taken on its composition levels.Uruguay has emerged as medium-size rice producer and Latin America's major rice exporter, and is now amongst the world's top ten. Thus, the knowledge of toxic as well as micronutrient elements is very important. Here is reported the determination in forty nine samples of rice (Oryza sativa L. of As, Cd, Cr, and Pb by ET AAS in samples digested by dry ashing, and Ca, Co, Cu, Fe, K, Mg, Mo, Mn, Na, Ni and Zn by FAAS and Hg by CV AAS using microwave-assisted decomposition.The amount of all the metal ions studied in this work fall within the range typical of rice around the world. All the rice samples tested showed lower levels of As, Cd, Hg and Pb than the maximum limit permitted by governmental and international organizations.Potassium was the most abundant mineral followed by Mg and Ca and amongst microelements the presence of Cu, Fe, Mo, Mn, Na and Zn was outstanding.The milling process highly affects the contents of K, Mg, Mn, Na and Zn while little influence has on Ca, Co, Cu and Fe concentrations.Unexpected loss of Ca, Fe and Mn during parboiling process was detected.

Dans ce roman-témoignage – pour reprendre la terme proposé par Miguel Barnet, l’auteur rapporte à la première personne le massacre de 12 000 à 20 000 présumés Haïtiens par les hommes de main du Trujillo en 1937. L’événement est un des moments décisifs de la dictature : il en marque profondément le caractère raciste et sanctionne les relations de violence entre l’État et la population. Dénonciatrice, l’œuvre cherche à rétablir la vérité des faits contre les mensonges de la propagande officielle. Nourri par cette volonté d’authenticité, le roman présente de façon dynamique et synthétique les bouleversements que subit la société dominicaine soumise à l’État dictatorial.

    Conzelmann, G.; Veselka, T.; Decision and Information Sciences

    2008-03-04

    Uruguay is in the midst of making critical decisions affecting the design of its future energy supply system. Momentum for change is expected to come from several directions, including recent and foreseeable upgrades and modifications to energy conversion facilities, the importation of natural gas from Argentina, the possibility for a stronger interconnection of regional electricity systems, the country's membership in MERCOSUR, and the potential for energy sector reforms by the Government of Uruguay. The objective of this study is to analyze the effects of several fuel diversification strategies on Uruguay's energy supply system. The analysis pays special attention to fuel substitution trends due to potential imports of natural gas via a gas pipeline from Argentina and increasing electricity ties with neighboring countries. The Government of Uruguay has contracted with Argonne National Laboratory (ANL) to study several energy development scenarios with the support of several Uruguayan institutions. Specifically, ANL was asked to conduct a detailed energy supply and demand analysis, develop energy demand projections based on an analysis of past energy demand patterns with support from local institutions, evaluate the effects of potential natural gas imports and electricity exchanges, and determine the market penetration of natural gas under various scenarios.

    Full Text Available Los primeros cronistas de la conquista del Río de la Plata expusieron la diversidad cultural reinante en el área en el siglo XVI. Las investigaciones arqueológicas de los años 60 y 70 confirman, a nivel arqueológico, la intensa ocupación de la que fue objeto esta zona próxima a la confluencia del río Paraná con el río Uruguay. Este trabajo presenta información producida durante un trabajo de diagnóstico realizado en el marco de la llamada Arqueología Pública, en un sitio de ocupación española del siglo XVI ubicado al oriente de dicha confluencia. Los resultados muestran que la ocupación del sitio desde el año 1000 AP está caracterizada por una amplia diversidad de estilos cerámicos. El área constituyó un lugar estratégico para los asentamientos europeos en función de la presencia de redes de intercambio pre existente. La información producida permite afinar la secuencia cronológica prehistórica para el bajo río Uruguay, al tiempo que abre el debate  respecto de la dinámica etnohistórica regional y del rol jugado por este particular asentamiento humano.   Palabras claves: asentamientos europeos, Uruguay, río San Salvador, siglo XVI.    Abstract Early chroniclers of the conquest of the Río de la Plata exposed the cultural diversity prevailing in the area in the sixteenth century. Archaeological research during the 60’s and 70’s confirm an intense occupation of the confluence of the Paraná river and the Uruguay river area. This paper presents information recovered during a diagnostic fieldwork developed on a Spanish settlement from the sixteenth century. The results show an intense occupation of the site since 1000 AP, characterized by a wide variety of ceramic styles. The area was a strategic location for European occupation due to the presence of preexisting exchange networks. Information produced refines prehistoric chronological sequence for lower Uruguay river while opening the discussion about regional

  17. Geographic autocorrelation analysis of the lung cancer mortality in Uruguay

    International Nuclear Information System (INIS)

    Objective: To analyze the geographical distribution of mortality from lung cancer in Uruguay, using spatial autocorrelation indicators, in order to identify regions of high and low risk in the period 1989-2008. Methodology: 1989-2008 interval was analyzed by grouping the data in the following periods: 1989-1991,1992-1994,1995-1997,1998-2000,2001-2003 and 2004-2008. As indicator risk S MR (Standardized Mortality Ratio) was used, with reference to the country as a entirety. The analysis was performed by calculating the index I and correlation plots space (both methods according Mo ran) for each period and the corresponding maps. The significance was determined by permutations, considering level 0.05 significance. Results: The results of the correlation coefficients for different periods were, in Men: 1989 -1991 (R = 0.29, p <0.05), 1992 -1994 (I = 0.11, N S), 1995 -1997 (R = 0.31, p <0.05); 1998 - 2000 (R = 0.24, p <0.05); 2000 - 2003 (R = 0.19, p <0.05); 2004 -2008 (R = 0.24, N S). In women: 1989 -1991 (R = -0.18, N S), 1992 -1994 (R = -0.16, N S), 1995-1997 (I = 0.18, N S); 1998 - 2000 (R = 0.06, N S); 2001-2003 (R = -0.16, N S), 2004 -2008 (I = 0.02, N S), 1989-2003 (R = -0.03, N S). Men in those departments where they met more risks Artigas were low (SM R = 0.52; 0.57; 0.61; 0.61; 0.60; 0.69), Salto (SM R = 0.52; 0.57; 0.58; 0.68; 0.76; 0.75), Black River (SM R = 0.69; 0.73; 0.76; 0.93; 0.73; 1.29) and Paysandu (SMR = 0.87; 0.85; 0.96; 0.79; 0.89; 0.92) in the respective periods. In women the 0.55; 0.78) Also, in the respective periods. Given the low number of cases in women the period 1989-2003 was also considered together to obtain one SMR Black River = 0.63 and jumped SMR = 0.68. Conclusions: In men, the existence of spatial autocorrelation was identified statistically significant, with stable results in the last 2 decades analyzed. This was not observed in women. The results found in males suggest the existence a region of lower mortality from lung cancer

  18. Improving radiation sterilization dose of bone tissue in Uruguay

    International Nuclear Information System (INIS)

    Full text: Since 2002 our tissue banks policy is to deliver radiosterilized bones in order to deliver safety and reliable tissues for clinical uses.The objective of this paper is to demonstrate that sterile or most clean environment for bone tissue retrieval, the INDT maintains the low bioburden and it could decrease the radiation sterilization dose of processed bone tissue following Good Processing Practices. Bones were retrieved from cadaveric and brain death multiorganic donors with informed consent, according to 14.005 and 17.668 Transplant Laws and 160/06 Decret. Between 2005 and 2007, 157 long bones (mostly femur and tibia) were retrieved. 101 structural bones were used for patients with tumors, total hip revision replacement and trauma surgery, and 10 kg. were used in spine, benign tumors and bucomaxillary surgery. All batches were radiosterilized in a Gamma cell unit. Radiation dose was determined according tissue bioburden. The bioburden were analyzed during 1 year simultaneously in (Ezeiza CNEA and INDT microbiological Lab), and then by our microbiological Lab. after quality certification. The proceeding of Radiation as well as the radiation dose determination were monitorized by AIEA/URU/7/005 Project. Bioburden was studied using AIEA Code of Practice approved technique. The Co-60 source used were the Energy Committee - Ezeiza Plant in Bs. As. And since June 2007 Uruguay got a Radiation Unit (Gamma cell 220 Excel) through AIEA URU 2005/003 RQ-URU/7/005 Project. In 2002 bioburden was between 0.1 and 0.3 CFU/cc for frozen bones and freeze dried bones, showing a radiation dose lower than 25 kGy. During the period 2005 - 2007 the bioburden rate was about 0.1 CFU/cc and the radiation dose between 15.2- 25 kGy. We point out that we keep bioburden and radiation sterilization dose in the same rate and the Good Processing Practices are the key to warranty microbiologically safety tissues. (Author)

    Full Text Available Investigou-se a atuação de uma rocha com espodumênio como fundente em massas cerâmicas, analisando-se sua reatividade com outras matérias-primas, como quartzo e caulim. Primeiramente, caracterizou-se petrograficamente o pegmatito de onde se extrai esse fundente. Posteriormente avaliou-se o comportamento de moabilidade, fundência e deformação piroplástica da rocha com espodumênio. Analisou-se então sua influência nas propriedades tecnológicas finais das peças, principalmente em relação à temperatura de queima, às fases e à microestrutura. Comparou-se a gresificação com outros fundentes comerciais como a albita e o feldspato. O espodumênio mostrou maior capacidade de reduzir a temperatura de gresificação das peças que os fundentes tradicionais, promovendo a densificação por fluxo viscoso.A spodumene rock was used as a flux in ceramic bodies, analyzing its reactivity to other raw materials such as quartz and kaolin. The petrology properties of the pegmatite (parent rock from which the flux is extracted was characterized. The grindability, fluxing strength and pyroplastic deformation of the spodumene rock were investigated. The influence on technological properties of the final pieces, mainly in relation to the firing temperature, phases formation and microstructure were also further analyzed. The firing behavior to other commercial flux such as albite and feldspar were then compared. The spodumene rock was considered an effective flux, capable of reducing the firing temperatures of the tested bodies by viscous flow.

    With debate escalating in regard to the prolonged contemporaneity of neandertal and modern human groups in the Franco-Cantabrian region on the one hand, and the late persistence of neandertals (until ca. 28-30,000 B.P.) and Mousterian industries in southern Iberia on the other; sites with Mousterian-Upper Paleolithic sequences from northern Spain play a pivotal role in the ongoing investigation of the Middle-Upper Paleolithic transition in western Europe. An important line of inquiry into the nature of social and economic change from the Middle to Upper Paleolithic is the monitoring of shifts in land use and resource procurement patterns. The recognition of short-term, seasonal patterning in settlement and resource provisioning may provide insights into changes in mobility, territoriality, and social organization that might otherwise be missed. This paper presents results of a seasonality study of fauna from archaeological levels spanning the Middle-Upper Paleolithic transition from the sites of El Castillo, El Pendo, and Cueva Morín in Cantabrian Spain. Data concerning season of death and age at death of prey animals presented here are derived from dental growth mark (increment, annuli) analysis. These data, along with other artifactual and faunal evidence suggest to us that: (1) economic strategies and technologies pervasive in the Upper Paleolithic are rooted in the Cantabrian Middle Paleolithic; and, (2) the apparent increase in deposits from the Middle through Upper Paleolithic may be the signature of a gradual increase in logistical economic strategies including the heightened level of social organization required for their implementation.

    Full Text Available El objetivo de este artículo es subrayar la naturaleza contracíclica de la banca pública comercial. Esto se hará mediante un análisis histórico de las crisis bancarias en Argentina y Uruguay a principios del siglo xxi. Este tipo de banco abarcó en Argentina varios actores cruciales dentro de las exitosas políticas de resolución de crisis y de reestructuración financiera; mientras en Uruguay, la banca pública comercial tuvo un papel menor durante la fase de resolución de la crisis, pero jugó un papel fundamental en la minimización de los riesgos del sistema financiero que en parte provocaron la crisis de 2002.

    Full Text Available ABSTRACT We describe a new species of a substrate-brooding Gymnogeophagus , based on coloration characters. The new species can be distinguished from the remaining substrate-brooding species in the genus by the unique pigmentation of the dorsal fin which consists of light blue, diagonal stripes over a red background in the spiny section and a combination of round, elliptic, and elongated bright blue spots over a red background in the soft section. It can be further distinguished from all other species of Gymnogeophagus by the following combination of characters: a discontinuous bright blue band above the upper lateral line in the humeral area, light blue roundish spots over a red to orange background on the anal fin, and conspicuous bright blue horizontal bands on body. The new species inhabits a wide range of freshwater habitats in the lower rio Uruguay basin, Rio de la Plata coastal drainages and Atlantic Ocean coastal drainages in Uruguay.

    The way that immigrants integrate into recipient societies has been discussed for decades, mainly from the perspective of the social sciences. Uruguay, as other American countries, received diffferent waves of European immigrants, although the details of the process of assimilation, when it did occur, are unclear. In this study we used genetic markers to understand the process experienced by the Basques, one of the major migration waves that populated Uruguay, and their relation to other immigrants, as well as to Native American and African descendants. For this purpose, we analyzed the allele frequencies of 10 ALU loci (A25, ACE, APOA1, B65, D1, F13B, PV92, TPA25, HS2.43, and HS4.65) in three samples from Uruguay (two of Basque descendants, one of non-Basque descendants) from two locations: Montevideo and Trinidad. No departure from Hardy-Weinberg expectations was observed, with the exceptions of the APOA1 and D1 loci in the non-Basque descendants' samples. Our data show that the major genetic contribution in the three samples comes from Europe (78-88%), with minor African (10-15%) and Native American (0-10%) contributions. Genetic distances reveal that Basque descendants from Trinidad cluster with Europeans, whereas both Montevideo samples cluster together and are separate from other populations, showing two diffferent types of integration, related to the general characteristics of each regional population.

    The paleomagnetic studies in Uruguay have been applied as a complementary tool to geological studies. Paleomagnetic data can be very useful for geodynamic reconstructions, fundamentally for determine the latitudinal tectonic transport, rotations of crustal blocks. This technique has been applied to Paleoproterozoic, Neoproterozoic and Paleozoic units. The geology of the Uruguayan territory is divided into four tectonic units of Uruguay that include a) the Piedra Alta tectonostratigraphic terrane (PATT) and b) Nico Pérez tectonostratigraphic terrane (NPTT), separated by the Sarandí del Yí high-strain zone. Both terranes are well exposed in the Río de La Plata craton (RPC) and have paleoproterozoic ages, the last was reworked in Neoproterozoic times (metacraton). The most thoroughly investigated Neoproterozoic sections are located in the eastern and southeastern regions of Uruguay. The c) Dom Feliciano Belt shows a tectonic evolution from back-arc to foreland basin characterized by fold-and-thrust, thick-skinned belts developed during the Brasiliano/Pan-African orogenic cycle. And finally d) The high metamorphic grade Punta del Este terrane where its most notable feature is their African affinity. There is a significant shortage of geochemical and geochronological data for the existing geological complexity.

    Uruguay is a middle-income country and the smallest in South America. Its population is under 3.3 million. The demographic and epidemiological characteristics are similar to those of developed countries, with a high burden associated with congenital anomalies. Infant mortality rate (IMR) decreased from 37/1000 live births, in 1980, to 8.8/1000, in 2013. This is largely explained by medical and social policies. IMR related to congenital anomalies, however, remained unchanged for the last 30 years. Therefore, programmes for prevention of congenital disorders were developed, such as the National Newborn Screening Programme. Mandatory, universal, free infant screening was implemented two decades ago. The Ministry of Public Health created the Comprehensive Plan on Birth Defects and Rare Diseases (PIDCER), to develop a strategic public policy tool enabling comprehensive, universal, quality care during their entire lifetime. Recent national legislation created provisions for newborn and infant screening, including for congenital hypothyroidism, phenylketonuria, congenital adrenal hyperplasia, cystic fibrosis and medium-chain acyl-CoA dehydrogenase, via blood spot test, otoacoustic emissions, systematic physical examination and hip ultrasound. We discuss how this programme was implemented, the current situation of rare diseases, the institution managing disability in Uruguay and the development of new laws based on the MPH's PIDCER. It illustrates how Uruguay is developing public policies in the genomic era, based both on science and bioethics. PMID:26021874

    Full Text Available Esse artigo apresenta uma metodologia para incorporação de incertezas à modelagem numérica pelo método dos elementos distintos em análises de confiabilidade estrutural de escavações em rocha. A metodologia foi desenvolvida levando em conta que os métodos de modelagem numérica normalmente empregados fornecem resultados pontuais, determinados a partir de parâmetros de entrada fixos, sem que sejam considerados seus respectivos erros. Entretanto a análise da estabilidade de estruturas em rocha envolve incertezas decorrentes da variabilidade inerente aos processos geológicos, da incerteza a respeito da hipótese de comportamento mecânico adotada e, também, das incertezas associadas aos parâmetros adotados na formulação do modelo numérico. Essas fontes de incerteza podem ser levadas em conta em modelos determinísticos simples, mas, na modelagem numérica, onde os resultados são de diversas naturezas, cabendo ao pesquisador analisá-los para obter suas conclusões, faz-se necessário o desenvolvimento de uma metodologia nova, baseada em simulações de Monte Carlo, com o emprego dos princípios da Lógica Paraconsistente, e que será apresentada na análise de um talude final de uma cava de mineração de grandes dimensões.A methodology for rock-excavation structural-reliability analysis that uses Distinct Element Method numerical models is presented. The methodology solves the problem of the conventional numerical models that supply only punctual results and use fixed input parameters, without considering its statistical errors. The analysis of rock-excavation stability must consider uncertainties from geological variability, from uncertainty in the choice of mechanical behaviour hypothesis, and from uncertainties in parameters adopted in numerical model construction. These uncertainties can be analyzed in simple deterministic models, but a new methodology was developed for numerical models with results of several natures. The

    Objective To assess the impact of different health warning labels (HWL). Material and Methods Data from the International Tobacco Control Survey (ITC Survey) were analyzed from adult smokers in Brazil, Uruguay and Mexico, each of which used a different HWL strategy (pictures of human suffering and diseased organs; abstract pictorial representations of risk; and text-only messages, respectively). Main outcomes were HWL salience and cognitive impact. Results HWLs in Uruguay (which was the only country with a HWL on the front of the package) had higher salience than either Brazilian or Mexican packs. People at higher levels of educational attainment in Mexico were more likely to read the text-only HWLs whereas education was unassociated with salience in Brazil or Uruguay. Brazilian HWLs had greater cognitive impacts than HWLs in either Uruguay or Mexico. HWLs in Uruguay generated lower cognitive impacts than the text-only HWLs in Mexico. In Brazil, cognitive impacts were strongest among smokers with low educational attainment. Conclusions This study suggests that HWLs have the most impact when they are prominent (i.e., front and back of the package) and include emotionally engaging imagery that illustrates negative bodily impacts or human suffering due to smoking.

    Aichivirus 1 (AiV-1) is an enteric virus with 30 nm in diameter, belonging to the genus Kobuvirus in the Picornaviridae family being a causative agent of gastroenteritis in humans. The transmission is via the fecal-oral route, through person to person contact, recreation in contaminated waters, or through the consumption of contaminated food or water. The aim of this study was to determine the frequency and the molecular characterization of AiV-1 in wastewater from Uruguay. Biweekly collections from March 2011 to February 2012 were performed in the cities of Bella Unión, Salto, Paysandú, and Fray Bentos, northwestern region of Uruguay. A total of 96 samples were collected; viruses were concentrated by ultracentrifugation, and AiV-1 was detected by using a nested PCR with primers directed to a conserved region (3CD junction) of the viral genome. A high frequency of AiV-1 (n = 54) was observed at all the cities analyzed mainly in the colder months of the year. AiV-1 was not evidenced as an appropriate viral fecal indicator since when compared with other previously detected enteric viruses, no correlation was observed. All 13 characterized AiV-1 belonged to the genotype B after the phylogenetic analysis performed with the sequences obtained from the first round PCR amplicon. This study demonstrates that AiV-1 is a frequently detected enteric viruses present in wastewater and excreted by infected persons in the northwestern region of Uruguay. PMID:26456918

    Full Text Available Depuis un certain temps, les discussions sur les passés récents et violents, connus lors des années 1960-1980, sont l’un des enjeux majeurs des espaces publics dans plusieurs pays de l’Amérique du Sud. L’Uruguay, ayant vécu un régime civique militaire fortement répressif entre 1973 et 1985, n’a pas été l’exception. Pourtant, bien que les mémoires publiques sur ce passé aient traversé différentes périodes, c’est la disparition des personnes qui conduit presque toute l’histoire des luttes autour de la mémoire du pays. Dans ce texte, nous nous attelons à tracer l’histoire de la mémoire des disparus politiques dans l’arène publique en Uruguay pour connaître les motifs qu’ont faits des disparus de l’image du passé récent.Discussions on violence during the years 1960-1980 in South America have for some time been a central issue in the public space of many South American countries. Uruguay, having gone through a strongly repressive civic-military regime between 1973 and 1985, was no exception. While public memories on this period have gone through different phases, the forced disappearances have always been the main focus of the struggles for memory. This article attempts to trace the history of the remembering of these victims of forced disappearance in the Uruguayan public arena in order to determine memory patterns in the image of a recent past.

    Grapevine phylloxera, Daktulosphaira vitifoliae (Fitch) (Hemiptera: Phylloxeridae) is a worldwide pest of Vitis species. It has forms that feed on leaves and roots. Root forms predominate on Vitis vinifera (L.) cultivars, while leaf forms predominate on Vitis species from its native American range. Recently, high densities of D. vitifoliae infestations in leaves of V. vinifera in Brazil, Peru, and Uruguay have been reported. The aims of this study were to determine the seasonal development of grape phylloxera, quantify infestation levels on V. vinifera leaves, and compare them with infestation levels on leaves of a rootstock of American origin. Studies were conducted in two vineyards in Uruguay from 2004-2007. Terminal shoots of 3309 C and Cabernet Sauvignon, Chardonnay, Tannat, Viognier, grafted onto resistant rootstock, were sampled weekly and leaves examined for gall presence and insect life stage. First galls were detected in early October; eggs began to appear within two weeks. Two oviposition peaks occurred by the end of December, and they coincided with bursts of shoot growth. On 3309C rootstock, oviposition peaks were more frequent than on the European cultivars. Based on thermal accumulation, D. vitifoliae could complete eight generations a year in Uruguay. Rootstock 3309C suffered the greatest damage but in some cases was similar to the European cultivars. Damage to Chardonnay, Cabernet Sauvignon and Viognier were also high. There were no galls on Tannat. The 2005-2006 season was characterized by low infestation rates caused by a prolonged drought that affected vegetative growth. There were also differences between vineyards, where the vigorous plants suffering more damage. Leaf galling phylloxera incidence and damage were mainly associated to the cultivar but plant vigor and environmental factors also contributed to increase the incidence. PMID:23667822

    Full Text Available Comparou-se as características químicas, físicas e mineralógicas de Latossolos Roxos desenvolvidos de rocha alcalina (LRe e de rocha eruptiva básica (LRd, da região de Jaboticabal, SP. Os resultados indicaram que o LRe apresenta-se num estádio de desenvolvimento, comparativamente, menos evoluído que o LRd, enquanto esse se apresenta com tendência para a maturidade. Os menores teores de argila e ferro total e maiores teores de saturação por bases, Ki e CTC da fração argila apresentados pelo LRe comprovam esta tendência. Conclui-se que a ocorrência de Latossolo Roxo eutrófico no campus da UNESP-Jaboticabal, pode estar associada a participação de rochas alcalinas na sua pedogênese.A comparative study was carried out on chemical, physical and mineralogical characteristics of dusky red latosols originated from the weathering of alcaline (LRe and basic eruptive rocks (LRd, of the Jaboticabal country Brazil The results showed that the LRe presented a younger development stage than LRd, while this soil showed a tendency to maturity. This trend was corraborated through the lower clay and total Fe2O3, contents and higher base saturation contents, Si2O/Al2O3 molecular ratio (Ki and clay f ration CEC presented by LRe. It can be concluded that the occurrence of eutrophic dusky red latosols hi the UNESP-Jaboticabal campus may be due to the influence of alcaline rocks.

    Full Text Available Abstract Background Bladder cancer is the fourth most frequent malignancy among Uruguayan men. A previous study from Uruguay suggested a high risk of bladder cancer associated with maté drinking. We conducted an additional case-control study in order to further explore the role of non-alcoholic beverages in bladder carcinogenesis. Methods In the time period 1996–2000, 255 incident cases with transitional cell carcinoma of the bladder and 501 patients treated in the same hospitals and in the same time period were frequency matched on age, sex, and residence. Both cases and controls were face-to-face interviewed on occupation, tobacco smoking, alcohol drinking and intake of maté, coffee, tea, and soft drinks. Statistical analysis was carried out by unconditional multiple logistic regression. Results Ever maté drinking was positively associated with bladder cancer (odds ratio [OR] 2.2, 95% confidence interval [CI] 1.2–3.9 and the risk increased for increasing duration and amount of maté drinking. Both coffee and tea were strongly associated with bladder cancer risk (OR for coffee drinking 1.6, 95% CI 1.2–2.3; OR for tea drinking 2.3, 95% CI 1.5–3.4. These results were confirmed in a separate analysis of never-smokers. Conclusion Our results suggest that drinking of maté, coffee and tea may be risk factors for bladder carcinoma in Uruguay.

    Full Text Available This paper compares parties and citizen behavior in the referendum and plebiscite of 1989 and 2009 in Uruguay, concerning the derogation or repeal of articles of the amnesty law, as well as the unfinished epilogue of this process. This will allow us to observe a change in the axis-force that drives citizens' initiatives in the matter. While in 1989 the Frente Amplio (FA assumed and promoted the derogatory referendum, in 2009 the social organizations won the centrality of the scene. In that last year the negative position and subsequent support for the plebiscite campaign by the partisan left. Its virtual absence from the coalition generates doubts about the management of the demands concerning human rights and the ethical-doctrinal nature of the partisan left. Although in 2010 the FA tried to resume leadership, it was weakened by an internal dispute that resulted in contempt towards the legislative debate to neutralize the effects of the act. The civic, identity and perhaps political configuration of the XXI century Uruguay will depend on the resolution of this gap.

  4. Analysis of radiation exposure to medical staff and patients during ERCP in Uruguay

    International Nuclear Information System (INIS)

    Background.The ERCP procedure requires the use of fluoroscopy with the subsequent exposure to ionizing radiation. The doses received by patients, physicians and assistants in the endoscopy have never been recorded in our area. This analysis describes the findings of the MIREDUy study (measuring radiation in digestive endoscopy in Uruguay). Objective. To determine radiation exposure received by patients, physicians and assistants during ERCP. Methods. Data were collected from 33 procedures conducted by four endoscopists, supported by endoscopy assistants. All staff took basic radiation-protection measures. The magnitudes measured were the kerma area product (KAP) for the patient and the effective dose (E) and the equivalent doses in hand (HM) and lens of the eyes (HC) for the operators. Results. Mean value for PKA was 24 Gy.cm2 (range: 0.04-71) equivalent to 312 chest x-rays. The mean fluoroscopy time was 2.3 minutes (range: 0.45 a 5.70 minutes). The E mean per procedure was 3.69, 5.14 y 3.69 μSv, for physician, first and second assistant respectively. The dose in hand for the physician was 19.4 μSv and the dose in lens was 7.94 μSv. Conclusions. The first results of measuring ERCP radiation doses in Uruguay are presented. These procedures expose the patient and staff to measurable radiation doses, which should be taken into account to minimize their risks. (authors)

  5. SEM - EDS mineralogical study of the Cuaro Sill Tacuarembo dept. (Uruguay)

    International Nuclear Information System (INIS)

    The Mesozoic magmatism exposed in the Norte basin of Uruguay is related with the tectono-magmatic events of the South Atlantic Ocean opening and, regionally is part of the Parana Magmatic Province (PMP). It is represented by basaltic flows correspondent to the Arapey Formation and by the associated intrusive rocks of the Cuaro Formation. The aim of this work is the mineralogical characterization of the Cuaro Sill (Department of Tacuarembo, NE Uruguay), using conventional petrographic techniques (polarized transmitted and reflected microscopy) and scanning electron microscopy (SEM-EDS). Based on the petrographic features observed, the dolerites of the Cuaro Sill are composed by: plagioclase (labradorite), pyroxenes (augite and pigeonite), Fe-Ti oxides (magnetite and ilmenite), relicts of olivine and apatite. It presents frequent glomero-porphyritic textures, with plagioclase/clinopyroxene phenocrysts, with lack of cumulate textures. Anomalous concentrations of guide exploration elements have not been observed despite the presence of traces of Mn and Cr within the ilmenites or the presence of sulfides (chalcopyrite). Therefore, a greater potential of these elements at deeper levels of the intrusion is not rule out

    2014-07-01

    Legal reforms in the Americas are influencing the public debate on cannabis policy. Uruguay and the two US states of Colorado and Washington have taken steps to regulate and legitimize the production, distribution, and use of cannabis and its derivatives. Earlier experiences with medical cannabis in the United States and limited access and production models in Europe have been insightful. However, these reforms are going further still, venturing into a new area of cannabis policy. A lack of empirical evidence regarding the effects of such reforms poses a challenge for policymakers. These examples will inform the design and implementation of any future cannabis policies. Therefore, a clear understanding of the details of each jurisdiction is necessary in developing future legal changes. Literature comparing the models of Uruguay, Colorado, and Washington is thin. This paper is based on an exhaustive examination of the laws, regulations, and discussions with regulators and functionaries of each jurisdiction. The research and analysis herein will provide policymakers with a greater understanding of the laws and regulations relevant to legal cannabis in these three jurisdictions, as well as draw to their attention some potential impacts and challenges of cannabis reform that require additional consideration to ensure public safety and health.

    Fusarium graminearum sensu stricto (F. graminearum s.s.) is the major causal agent of Fusarium head blight of wheat worldwide, and contaminates grains with trichothecene mycotoxins that cause serious threats to food safety and animal health. An important aspect of managing this pathogen and reducing mycotoxin contamination of wheat is knowledge regarding its population genetics. Therefore, isolates of F. graminearum s.s. from the major wheat-growing region of Uruguay were analyzed by amplified fragment length polymorphism assays, PCR genotyping, and chemical analysis of trichothecene production. Of the 102 isolates identified as having the 15-ADON genotype via PCR genotyping, all were DON producers, but only 41 strains were also 15-ADON producers, as determined by chemical analysis. The populations were genotypically diverse but genetically similar, with significant genetic exchange occurring between them. Analysis of molecular variance indicated that most of the genetic variability resulted from differences between isolates within populations. Multilocus linkage disequilibrium analysis suggested that the isolates had a panmictic population genetic structure and that there is significant recombination occurs in F. graminearum s.s. In conclusion, tour findings provide the first detailed description of the genetic structure and trichothecene production of populations of F. graminearum s.s. from Uruguay, and expands our understanding of the agroecology of F. graminearum and of the correlation between genotypes and trichothecene chemotypes.

    Full Text Available At first Rickettsia conorii was implicated as the causative agent of spotted fever in Uruguay diagnosed by serological assays. Later Rickettsia parkeri was detected in human-biting Amblyomma triste ticks using molecular tests. The natural vector of R. conorii, Rhipicephalus sanguineus, has not been studied for the presence of rickettsial organisms in Uruguay. To address this question, 180 R. sanguineus from dogs and 245 A. triste from vegetation (flagging collected in three endemic localities were screened for spotted fever group (SFG rickettsiosis in southern Uruguay. Tick extracted DNA pools were subjected to PCR using primers which amplify a fragment of the rickettsial gltA gene. Positive tick DNA pools with these primers were subjected to a second PCR round with primers targeting a fragment of the ompA gene, which is only present in SFG rickettsiae. No rickettsial DNA was detected in R. sanguineus. However, DNA pools of A. triste were found to be positive for a rickettsial organism in two of the three localities, with prevalences of 11.8% to 37.5% positive pools. DNA sequences generated from these PCR-positive ticks corresponded to R. parkeri. These findings, joint with the aggressiveness shown by A. triste towards humans, support previous data on the involvement of A. triste as vector of human infections caused by R. parkeri in Uruguay.

    We present in this work the development of astronomy in Uruguay since the colony times up to the present, stressing in particular those aspects related to the formal as well as informal teaching of astronomy. The first antecedents of astronomical studies in our country go back to the beginnings of the XVIIIth century related to the scientific expeditions from Europe coming to our shores. The teaching of astronomy was generalized at the high school level as soon as the end of the XIXth century, while itsintroduction at the university level happened much later, around the middle of the last century. We analyze the current situation of this subject, its problems, and some measures to strengthen its development.

    Full Text Available During each electoral period, the strategic interaction between voters and political elites determines the number of viable candidates in a district. In this paper, we implement a hierarchical seemingly unrelated regression model to explain electoral coordination at the district level in Uruguay as a function of district magnitude, previous electoral outcomes and electoral regime. Elections in this country are particularly useful to test for institutional effects on the coordination process due to the large variations in district magnitude, to the simultaneity of presidential and legislative races held under different rules, and to the reforms implemented during the period under consideration. We find that district magnitude and electoral history heuristics have substantial effects on the number of competing and voted-for parties and lists. Our modeling approach uncovers important interaction-effects between the demand and supply side of the political market that were often overlooked in previous research.En cada período electoral, votantes y élites interactúan para determinar el número de agentes políticos postulados para la elección, así como el número de agentes políticos que reciben apoyo de los votantes.

    Full Text Available An ecological, productive and social diagnosis of homegardens in Northern Uruguay is displayed in this paper, as well as methodology to achieve it, that could be used in other similar systems. The fieldwork consisted of interactive surveys to producers and field inventories for gathering information on the social, technical, productive and ecologicalaspects of green orchards. . A map of the orchards was done by using a Geographic Information System (GIS. The homegarden is organic, aligned along the minor and major roads and forms cluster cores at the interface between the urban and peri-urban areas. The prospects of the orchards are limited for socio-cultural reasons. Species biodiversity reached a total amount of 187 and an average of 23 species per orchard. Policies are needed for rescueing inherited knowledge that will keep homegardens alive.

    Freshwater fish present unique challenges when one attempts to understand the factors that determine the structure of their populations. Habitat fragmentation is a leading cause of population decline that threatens ecosystems worldwide. In this study, we investigated the conservation status of genetic variability in the Neotropical catfish (Pimelodus maculatus). Specifically, we examined the structure and genetic diversity of this species in a region of the Upper Uruguay River fragmented by natural barriers and dams. There was no genetic structure among the four sites analyzed, indicating the existence of only one population group. A combination of environmental management and genetic monitoring should be used to minimize the impact of impoundment on panmitic populations of migratory fish species. PMID:23271936

The general dominance of Aulacoseira spp. could be related to the polymictic condition of the system. In cold months phytoplankton distribution was homogeneous among sampling stations, while in warm months, spatial heterogeneity was detected, suggesting that sampling stations can behave as independent compartments.

    Full Text Available Understanding the problems faced by rural extension in Uruguay as well as the conceptions used by the development agents to conduct their practices constitutes a contribution to both, the Uruguayan rural development policies and the wider space of the MERCOSUR. A quali-quantitative research was conducted, during which 32 Uruguayan extensionists replied to a questionnaire. Replies underwent content and statistic analysis. Results suggest that the Uruguayan rural extensionists posses a complex conception of their practice, which articulates productive and social dimensions and relates to a critical and participatory way of understanding rural extension. Nevertheless, a diffusionist conception of rural extension is also present in some cases. Finally, problems related to group dynamics are highlighted.

    Ochratoxin A (OTA) is a nephrotoxic mycotoxin which has been found worldwide as a contaminant in wines. It is produced on grapes mainly by molds from Aspergillus section Nigri. This study has demonstrated for the first time the occurrence of black aspergilli on Tannat grapes from Uruguay, in a two year survey. Aspergillus uvarum (uniseriate) and Aspergillus welwitschiae (from Aspergillusniger aggregate) were the prevalent species whereas Aspergillus carbonarius which is considered the main OTA producing species was not detected. OTA production in culture medium was evaluated for native isolates from A. niger aggregate and compared to levels produced by a type strain of A. carbonarius. This work also includes the development of quick and easy molecular methods to identify black aspergilli to species level, avoiding sequencing. PMID:26398282

    2009-07-01

    Full Text Available This work presents new results of a detailed geological and structural investigation focusing the easternmost Uruguayan Mesozoic magmatic occurrences related to the south Atlantic opening. Lithological descriptions, their stratigraphic relationships and complimentary lithochemical characterizations carried out in the San Miguel region (East Uruguay are presented. Three volcanic/sub-volcanic units have been recognized. The felsic volcanic association is composed by rhyolitic - dacitic flows, mainly with porphyritic textures and sub-alkalinenature and related pyroclastic rocks. The felsic sub-volcanic association is characterized by granophyres of about 25 km2 of exposed area, cross- cut by mafic and felsic dykes. Finally, a mafic association has been identified characterized by dykes and a small intrusion of gabbroic composition.All these units are Mesozoic in age (130 - 127 Ma and according to their chemical nature they correspond tosub-alkaline to weak peralkaline magmas.

    This paper deals with the analysis of phytoplankton composition and abundance from four sampling stations at the polymictic system, Rinc6n del Bonete water reservoir in Uruguay. Sampling data were obtained in 4 seasonal periods between February and November 1993. A hundred and twenty-four taxa were identified, where Aulacoseira granulata (Ehrenb.) Simon., A. granulata var. angustissima (Muller) Simon., A. granulata var. angustissima f. spiralis, (Muller) Simon., A. cf. ambigua, (Grun.) Simon., A. cf. distans (Ehrenb.) Simon., Cryptomonas spp. and Synedra ulna (Nitzsch) Ehrenberg, were always present. Phytoplankton abundance fluctuated between 29 (autumn) and 2129 (summer) ind/ml. The general dominance of Aulacoseira spp. could be related to the polymictic condition of the system. In cold months phytoplankton distribution was homogeneous among sampling stations, while in warm months, spatial heterogeneity was detected, suggesting that sampling stations can behave as independent compartments.

    Colorado, Washington state and Uruguay are currently designing legal non-medical markets for cannabis. These clearly contravene the 1961 and 1988 drug conventions; options for what may happen next are discussed. The current provisions in the three regulatory schemes are summarized. From a public health perspective, the emphasis should be on holding down consumption with regulatory measures, but the public health agenda does not seem to be a strong consideration in the implementation of the US schemes, and they are paying little attention to what can be learned from the history of alcohol and tobacco regulation. While alternative paths to a cannabis market under the conventions are noted, the legalization initiatives underline the need to revise the drug conventions, making prohibition of domestic markets an optional matter. Such changes would also ease the path for including alcohol under the conventions, which would be an important step forward in global health. PMID:24180513

    Full Text Available El presente artículo tiene como objetivo realizar una revisión crítica de algunos documentos nacionales y textos académicos sobre las políticas de inclusión educativa en Uruguay. Se parte de los diversos significados y acepciones que tiene el término inclusión educativa, entendiendo que la misma debe brindar apoyo a la población de estudiantes más vulnerables ya sea por razones culturales, sociales, económicas o por su condición de discapacidad. Considerar la diversidad como parte de lo humano conduce a pensar en una educación en y para la diversidad, esta concepción de educación debe constituir el centro de la política educativa y el Estado deberá garantizar los recursos necesarios para su implementación. Se analizan algunos documentos del marco normativo internacional sobre inclusión social y educativa. Considerando que estos documentos refieren a la educación inclusiva como un derecho humano fundamental. Aún existe una gran distancia entre los discursos y las posibilidades efectivas de ejercer el derecho a la educación por parte de los niños en general y con discapacidad en particular. Uruguay mantiene en la actualidad un sistema de educación segregada, donde la situación educativa de los jóvenes con discapacidad hace figura y representa un gran desafío. Para finalizar, se identifica a la formación docente como uno de los componentes primordiales para el desarrollo de una educación inclusiva. El desarrollo profesional de los docentes es en sí mismo una estrategia de cambio y un factor clave para los procesos de mejora e innovación educativa. // This article aims to make a critical review of some national documents and academic texts on educational policies for inclusion in Uruguay.

    Objective: To determine the prevalence, correlates and changes in secondhand smoke (SHS) exposure over the period after comprehensive smoke-free policy implementation in two Latin American countries. Methods: Data were analysed from population-based representative samples of adult smokers and recent quitters from the 2008 and 2010 waves of the International Tobacco Control Policy Evaluation Survey in Mexico (n = 1766 and 1840, respectively) and Uruguay (n = 1379 and 1411, respectively). Prevalence of SHS exposure was estimated for regulated venues, and generalized estimating equations were used to determine correlates of SHS exposure. Results: Workplace SHS exposure in the last month was similar within and across countries (range: Mexico 20–25%; Uruguay 14–29%). At the most recent restaurant visit, SHS exposure was lower where comprehensive smoke-free policies were implemented (range: Uruguay 6–9%; Mexico City 5–7%) compared with Mexican cities with weaker policies, where exposure remained higher but decreased over time (32–17%). At the most recent bar visit, SHS exposure was common (range: Uruguay 8–36%; Mexico City 23–31%), although highest in jurisdictions with weaker policies (range in other Mexican cities: 74–86%). In Uruguay, males were more likely than females to be exposed to SHS across venues, as were younger compared with older smokers in Mexico. Conclusions: Comprehensive smoke-free policies are more effective than weaker policies, although compliance in Mexico and Uruguay is not as high as desired. PMID:23172895

    Full Text Available Austrolebias varzeae n. sp. is described from rio da Várzea floodplains, upper rio Uruguay basin, southern Brazil. It seems to be closely related to A. carvalhoi (Myers, with which it shares a similar color pattern of male and an apomorphic morphology of the autopalatine. The new species differs from A. carvalhoi by having more anal-fin rays in males and more caudal-fin rays. Austrolebias varzeae is distinguished from all other species of the genus by a unique color pattern, in which there are three distinctively darker and narrower bars on the anterior portion of male flank. Putative close relationships between A. varzeae and A. carvalhoi suggest a closely related biogeographic history between upper Uruguay and upper Iguaçu River basins, corroborated by a biogeographic pattern of the anablepid genus Jenynsia.Austrolebias varzeae sp. n. é descrita da várzea do rio da Várzea, bacia do rio Uruguai superior, sul do Brasil. Ela parece estar estreitamente aparentada a A. carvalhoi, com a qual compartilha um padrão de colorido similar e uma morfologia apomórfica do autopalatino. A nova espécie difere de A. carvalhoi por possuir mais raios na nadadeira anal de machos e mais raios na nadadeira caudal. Austrolebias varzeae se distingue de todas as espécies do gênero por um padrão de colorido exclusivo, no qual há três barras distintivamente mais estreitas e mais escuras na porção anterior do flanco do macho. As supostas estreitas relações de parentesco entre A. varzeae e A. carvalhoi sugerem uma história biogeográfica intimamente relacionada entre as bacias do rio Uruguai e do rio Iguaçu superiores, corroborada por um padrão biogeográfico do gênero anablepídeo Jenynsia.

  4. Geothermal energy: potential applications to diversify the energy matrix of Uruguay

    International Nuclear Information System (INIS)

    The Geothermal energy is a promising renewable energy source due to the low to null CO2 emissions and the stability of energy production. In Uruguay, high geothermal gradients related to magmatism are extinct since the Cretaceous, limiting its geothermal potential. However, a moderate geothermal gradient in northwest Uruguay is estimated at an average of ∼ 28.6 oC/km. Here, thermally insolating Cretaceous flood basalts confine aquifers in Carboniferous to Jurassic sedimentary rocks of the Parana basin. In this area geothermal applications are possible: 1) The over-pressurized, warm waters of the Guarani Aquifer System (∼45°, >1000 m), presently only used by the tourism industry, could be used for domestic or industrial heating (eg. greenhouses) to reduce the consumption of energy from other sources. 2) Waters from possibly deeper Carboniferous-Permian aquifers (≤75 °C, ∼2300 m), may allow the generation of electricity using binary power plants cooled by superficial cold water. If these or other sedimentary rocks extend deeper (≤150 °C, ∼4500 m), conventional binary plants could contribute to the national energy demand. 3) If viable, creating an enhanced geothermal systems in the granitic basement, below 5000 m depth, could also enable the generation of significant amounts of electricity with binary plants. To develop these scenarios, detailed research of the geothermal gradient and its variations at depths, the stratigraphy and structural geology of the Parana basin, the hydrogeology of its aquifers and the localization of granitic intrusions on the basement are needed. All the above, have yet to be systematically and comprehensively studied

    Full Text Available In this paper the author investigates, from a qualitative perspective, the problems associated with implementing educational innovations. He studies the recent case of the Basic Cycle reform in Uruguay. Based on the concepts of van der Vegt and Vandenberghe (1992, he analyzes the "functions guides" exercised by the director in order to be able to regulate the internal flow of the implementation. The first of these is "conceptual clarity", which has to do with providing the professors with a clear vision of what will take place within the implementation, and with specifying that vision in terms of the professional knowledge and abilities of the faculty as well. The second of these is "directional pressure," which refers to an operational level of the implementation; that is to say, how daily activities mesh with the objectives of the reform. Next, "function of support" refers to the support offered by the director for the management of resources (material, emotional, technical, and administrative resources, so that the resources may then effectively support the work in the center. Finally is "definition of latitude," that is, the degree of educational autonomy that the faculty have with respect to the external objectives of the reform. En este trabajo el autor estudia, desde una perspectiva cualitativa, la problemática de la implementación de innovaciones educativas. Toma por caso la reciente reforma del Ciclo Básico en Uruguay. Con base en los conceptos de van der Vegt y Vandenberghe (1992, analiza las "funciones guía" ejercidas por el director para poder regular el flujo interno de la implementación. La primera de ellas es la "claridad conceptual", que tiene que ver con las posibilidades de proveer a los profesores de una clara visión de lo que ha de lograrse con la implementación y con concretar esa visión en términos de saber profesional y habilidades de los docentes. La segunda es la "presión direccional" que refiere a un nivel

Dos de los 3 casos fueron seguramente provocados por Rickettsia conorii de acuerdo a los resultados de la reacción específica de inmunofluorescencia indirecta - IgM, anti R. conorii. Se incluye un tercer paciente no estudiado con tal técnica, por la similitud clínico-epidemiológica, la reactividad del suero frente al Proteus OX 19 y la rápida respuesta a la tetraciclina. La no descripción previa de la rickettsiosis por R. conorii en forma autóctona en el área de las Américas confiere especial interés a la comunicación, recomendándose la búsqueda de la afección en otros países de la región.Three autochthonous cases of cutaneous-ganglionar rickettsiosis transmitted by dogs ticks (Amblyomma maculatum in one of them are reported. Two of the three cases were undoubtely produced by Rickettsia conorii according to the results of the specific indirect immunofluorescence technique IEF-IgM anti R. conorii. A third case is included due to the clinical epidemiological similarity, the positive serum reactivity with Proteus O x 19 and the rapid response to tetracycline. Autochthonous rickettsiosis by R. conorii has not been previously registered in the American area what confers special interest to this communication. The search of the disease in the other countries of the region is suggested.

  10. Studies on post-partum reproductive performance of Hereford beef cows in Uruguay with the aid of progesterone assay

    International Nuclear Information System (INIS)

    A trial was undertaken on Hereford beef cows to determine the length of their post-partum (pp) anoestrous periods under traditional conditions of feeding and management in Uruguay. Three subsequent trials to shorten pp anoestrus involving early weaning (at 40 days pp), temporary weaning for 72 hours (at 45 days), and temporary weaning for 24 hours combined with GnRH, were run in different parts of Uruguay under different soil and pasture conditions. No treatment differences were found, but cows on improved pastures had shorter pp anoestrous periods (74, 99 and 102 days for the three trials respectively) and higher pregnancy rates (80%, 46% and 55% respectively). It was concluded that the main cause of low reproductive efficiency was poor nutrition and that, under such conditions, no treatment to shorten the pp anoestrus would ever be expected to be successful.

Os corpos de prova cerâmicos foram confeccionados com até 10% em massa de rejeito de rocha ornamental a seco, e em seguida, umedecidos e moldados por extrusão. Os materiais produzidos foram calcinados nas temperaturas de 700 ºC, 800 ºC e 900 ºC. Após 1060 h de degradação acelerada em equipamento de laboratório, analisaram-se as propriedades cerâmicas do material. Os resultados das resistências mecânicas foram comparados através da distribuição de Weibull, antes e depois da degradação. Nota-se que o material com adição de 10% de rejeito de rocha ornamental na massa cerâmica é mais confiável quando queimada a 900 ºC após a degradação, quando comparados com as amostras sem adição de rejeito, proporcionando maior durabilidade.For the evaluation of the accelerated degradation in laboratory of red ceramic specimens with addition of ornamental rock waste free from steel particles, an equipment that leach with hot and cool water and time control, and also freezing the specimen at -4 ºC was used,. The ceramic samples were made with up to 10 wt.% of the dry ornamental rock waste, and after humidifying and molding by extrusion. The specimens were fired at 700 ºC, 800 ºC and 900 ºC. After 1060 h of accelerated degradation lab test, ceramic properties were evaluated. The results of the strength were compared for Weibull distribution, before and after degradation. The specimens with addition of 10 wt.% waste is more durable and reliable when fired to 900 ºC after the degradation.

We describe the new records of Limnoperna fortunei in Uruguayan coast of Rio de la Plata, Santa Lucia, Negro and Uruguay Rivers. With these results we aim to estimate its distributional limits for Uruguay main hydrographical basins. We also deal with the role of salinity as the main abiotic factor in limiting the east distribution of this mussel in Uruguayan coast of Rio de la Plata and as a potential determinant of the "new" colonization on the Atlantic and the Merin Lagoon Basins.

  5. Nd-Sr isotopic compositions of dissolved and particulate material transported by the Parana and Uruguay rivers during high (december 1993) and low (september 1994) water periods

    International Nuclear Information System (INIS)

    Our motivation is to better constrain the neodymium and strontium isotopic signatures of the closest continental riverine source (Parana and Uruguay rivers) to the Brazil/Malvinas Confluence zone in the Southwest Atlantic Ocean. We thus present new isotopic data on the Nd and Sr of the dissolved and suspended loads of the Parana and Uruguay rivers for two water periods forming the Rio de la Plata whose drainage basin is the second largest one in South America. The Parana dissolved material shows less radiogenic (εNd (0) ranging between -12.1 and -8.2) than the Uruguay one with a mean εNd (0) value of -6.3 ± 0.3. Suspended particulates display the same isotopic trend (mean εNd (0) value of -10.3 and -6.0 for the Parana and Uruguay rivers, respectively). Dissolved load 87Sr/86Sr in the Parana (0.7123) is found to be more radiogenic than the Uruguay one (0.7097); the suspended load follows the same trend with 87Sr/86Sr ratios of 0.7247 and 0.7115 in the Parana and Uruguay rivers, respectively. The relatively radiogenic Nd and non radiogenic Sr of the Uruguay River as compared to the Parana River could be attributed to a predominance of tholeiitic basalts in the drainage basin. A revisited estimation of the fluxes of Nd considering all South American rivers delivering into the western South and Tropical Atlantic Ocean yields a Nd particulate flux to estuarine water two orders of magnitude higher than the Nd dissolved flux. Considering the net dissolved and suspended fluxes of Nd reaching the Rio de la Plata, we have calculated a resulting εNd (0) equal to -10.2. The computation of εNd (0) of the Rio de la Plata outflow waters gives a value of -8.3, taking into account various removal processes within the estuary. (authors)

    The extent of children's exposure to multiple toxic metals is not well described in many developing countries. We examined metal exposures in young children (6-37 months) from Montevideo, Uruguay and their mothers (15-47 years) participating in a community-based study. Hair samples collected from 180 children and their mothers were analyzed for: lead (Pb), cadmium (Cd), manganese (Mn), and arsenic (As) concentration using inductively coupled plasma-mass spectrometry (ICP-MS). Median metal levels ({mu}g/g) were: Pb 13.69, Mn 1.45, Cd 0.17, and As 0.09 for children and Pb 4.27, Mn 1.42, Cd 0.08, and As 0.02 for mothers. Of the child and maternal samples, 1.7% and 2.9% were below the limit of detection (LOD) for Cd, and 21.3% and 38.5% were below the LOD for As, respectively. Correlations between maternal and child levels ranged 0.38-0.55 (p < 0.01). Maternal hair metal levels were the strongest predictors of metal concentrations in children's hair. Girls had significantly lower As levels than boys (p < 0.01) but did not differ on other metals. In addition, in bivariate logistic regressions predicting the likelihood that the child would be exposed to multiple metals, hemoglobin < 10.5 g/dL (OR = 2.12, p < 0.05), blood lead (OR = 1.17, p < 0.01), and the mother being exposed to two or more metals (OR = 3.34, p < 0.01) were identified as significant predictors of increased likelihood of multiple metal exposure. Older child age (OR = 0.96, p < 0.05), higher maternal education (OR = 0.35, p < 0.01), and higher number of household possessions (OR = 0.83, p < 0.01) were significantly associated with decreased likelihood of multiple metal exposure. Preschool children in Uruguay are exposed to multiple metals at levels that in other studies have been associated with cognitive and behavioral deficits. Sources of exposure, as well as cognitive and behavioral consequences of multiple metal exposure, should be investigated in this population.

    Full Text Available In 2008, a 7-valent pneumococcal conjugate vaccine (PCV7 was introduced into the routine childhood immunization program in Uruguay, with a 2+1 schedule. In 2010, PCV13 replaced PCV7, and the same 2+1 schedule was used. The effect of these pneumococcal vaccines on the incidence of invasive pneumococcal infections (IPD and on serotype distribution was analyzed retrospectively, based on passive national laboratory surveillance.Data from 1,887 IPD isolates from 5 years before and 5 years after PCV7 introduction (7 before and 3 after PCV13 introduction was examined to assess the incidence rate per 100,000 age-specific population of all IPD, PCV7-serotypes, and PCV13-serotypes associated IPD among children < 2 years and 2 to 4 years old, and patients ≥ 5 years old. Trends of frequency for each serotype were also analyzed.Comparison of pre-vaccination (2003-2007 and post-vaccination (2008-2012 periods showed a significant decrease in IPD incidence among children < 2 years old (IR 68.7 to IR 29.6, p<0.001 and children 2 to 4 years (p < 0.04. IPD caused by serotypes in PCV7 was reduced by 95.6% and IPD caused by 6 serotypes added in PCV13 was reduced by 83.9% in children <5 years old. Indirect effects of both conjugate vaccines were observed among patients ≥ 5 years old one year after the introduction of each vaccine, in 2010 for PCV7 and in 2012 for PCV13. Nevertheless, for reasons that still need to be explained, perhaps due to ascertainment bias, total IPD in this group increased after 2007. In 2012, the relative frequency of vaccine serotypes among vaccinated and unvaccinated population declined, except for serotype 3. Non vaccine serotypes with increasing frequency were identified, in rank order: 12F, 8, 24F, 22F, 24A, 15C, 9N, 10A and 33.Consecutive immunization with PCV7 and PCV13 has significantly reduced IPD in children < 5 years of age in Uruguay.

    Full Text Available A new species of Austrolebias is described based on individuals from the middle and upper río Negro (río Uruguay basin and río Yaguarón (Patos-Merín system. The new species can be differentiated from all other species of the genus by the unique presence in males of uniform bluish gray pigmentation on flanks (without vertical bands and unpaired fins. The new species is also distinguished by the combination of characters associated with a reduction of the squamation of the abdominal, preopercular, and opercular regions. The new species presents some morphological characteristics similar to A. gymnoventris and A. luteoflammulatus. The distribution of the new species is concordant with three other species of Austrolebias and may represent a case of drainage rearrangement of the río Negro upstream tributaries (río Uruguay basin and tributaries of laguna Merín system.Uma espécie nova de Austrolebias é descrita, com base em indivíduos do alto e médio rio Negro (bacia do rio Uruguai e rio Jaguarão (sistema Patos-Mirim.

    2015-02-01

    Full Text Available The Permo-Triassic archosauromorph record is crucial to understand the impact of the Permo-Triassic mass extinction on the early evolution of the group and its subsequent dominance in Mesozoic terrestrial ecosystems. However, the Permo-Triassic archosauromorph record is still very poor in most continents and hampers the identification of global macroevolutionary patterns. Here we describe cranial and postcranial bones from the Permo-Triassic Buena Vista Formation of northeastern Uruguay that contribute to increase the meagre early archosauromorph record from South America. A basioccipital fused to both partial exoccipitals and three cervical vertebrae are assigned to Archosauromorpha based on apomorphies or a unique combination of characters. The archosauromorph remains of the Buena Vista Formation probably represent a multi-taxonomic assemblage composed of non-archosauriform archosauromorphs and a ‘proterosuchid-grade’ animal. This assemblage does not contribute in the discussion of a Late Permian or Early Triassic age for the Buena Vista Formation, but reinforces the broad palaeobiogeographic distribution of ‘proterosuchid grade’ diapsids in Permo-Triassic beds worldwide.

  20. Soil organic carbon and physical properties in vegetable farms in South Uruguay

    International Nuclear Information System (INIS)

    The South of Uruguay is the area of the country most severely affected by soil erosion and where the most important vegetable production area is located. Soil degradation has been aggravated by a process of intensification and specialization of the vegetable production due to an unfavorable socio-economic context and lack of adequate planning of the production systems. The objectives of this work were the description of current soil quality (Typic Hapluderts, Paquic (vertic) Argiudolls, and Abruptic Argiudolls) in 16 vegetable farms in the region, and the evaluation of the impact of improved management techniques on soil quality. We evaluated soil organic carbon (SOC), soil structure stability and the evolution of SOC in time. We found a degradation of soil quality under vegetable cropping compared to the reference sites, given by an average loss of SOC of 31 to 44% and 0.4 mm in structure stability. A linear regression model was fitted to explain the change in SOC content observed in fields under vegetable cultivation during the period under study. The change in SOC content was explained by the organic matter inputs by green manures and chicken bed, the initial SOC content and length of the period in years. This model is a simple tool to estimate the effect of soil organic amendments on SOC balance in soils under vegetable cropping in this region

    While it is known that toxic metals contribute individually to child cognitive and behavioral deficits, we still know little about the effects of exposure to multiple metals, particularly when exposures are low. We studied the association between children's blood lead and hair arsenic, cadmium, and manganese and their performance on the Bayley Scales of Infant Development III. Ninety-two preschool children (age 13-42 months) from Montevideo, Uruguay, provided a hair sample and 78 had a blood lead level (BLL) measurement. Using latent class analysis (LCA), we identified four groups of exposure based on metal concentrations: (1) low metals, (2) low-to-moderate metals, (3) high lead and cadmium, and (4) high metals. Using the four-group exposure variable as the main predictor, and fitting raw scores on the cognitive, receptive vocabulary, and expressive vocabulary scales as dependent variables, both complete-case and multiple imputation (MI) analyses were conducted. We found no association between multiple-metal exposures and neurodevelopment in covariate-adjusted models. This study demonstrates the use of LCA together with MI to determine patterns of exposure to multiple toxic metals and relate these to child neurodevelopment. However, because the overall study population was small, other studies with larger sample sizes are needed to investigate these associations. PMID:25694786

    Full Text Available This paper focuses on current research on early colonisation of the Atlantic coast of South America during the early Holocene. We present advances in the investigation of raw material procurement at the Rincón de los Indios site, located in the eastern part of Uruguay. The technological studies suggest that some aspects of different styles of projectile points are related with environmental adaptation processes, experienced by the first American people in the New World. The occupation of new spaces and new forms of exploitation of resources changes the organisation of lithic technology. The distance to good quality rocks were critical for the opportunities and economic organisation of hunting groups. The study of changes in lithic procurement strategies for projectile points helps us develop a more comprehensive knowledge of this important social adaptation process which occurred during this period. These patterns started to become stabilised in the latter part of the early Holocene across the extended territory and confirm the efficient land occupation associated an intensive hunter-gatherer economies.

  5. Sedimentology and mineralogy of Libertad formation (late pleistocene) related to local fauna La Paz (Montevideo- Uruguay)

    International Nuclear Information System (INIS)

    The Local Fauna La Paz (Montevideo, Uruguay) includes skeletal remains of taxa that are characteristic of the Late Pleistocene: Glyptodon clavipes, Doedicurus sp., Panochthus sp., Lestodon sp., Macrauchenia patachonica, Stegomastodon waringi, Toxodon platensis, among others. This paper aims to contribute to the understanding of sedimentary processes acting, considering litofaciological and mineralogical aspects of sediment involved, responsible for the accumulation of bonebed. To meet the targets was lifted a detail stratigraphic section; for mineralogical studies were collected representative samples from each individual litofacies and clays were treated for the purposes of being subjected to analysis by X-ray diffractometer. The study was supplemented with a textural and compositional observation of silt and sand fraction through binocular magnifier and petrographic microscope. According to the sedimentological aspects and some taphonomic features of the bonebed such as: facies settling, the absence of sedimentary structures (massive deposit) and grainselection, along with the complete dismantling and chaotic disposal of materials, and the degree of angularity of the largest clasts, it follows that a mud flow was the last reason on the transportation and deposition of remains. The results of the X-ray diffraction reveal the predominance of chlorites and smectites on sepiolite. Previous studies suggested that the lithostratigraphic unit including the remains was the Dolores Formation. However, considering the evolutionary Quaternary model and geomorphological appearance, we consider these sediments belonging to the Libertad Formation

  6. Lithosphere evolution during the pre devonian of Uruguay: Prevalence of strike slip faults

    International Nuclear Information System (INIS)

    The available data about mega shear zones were analyzed. Also the geo chronological trusty data about pre devonian rocks from Uruguay were overlapped. Emphasizing in the basic rocks, four tecto no-stratigraphy c terranes might be recognized. The approximate age of those rocks is known as well as the displacement trend. It can be concluded that the transmazonian age Piedra Alta Terrane (transmazonian age 2000 ± 100 My) is the most ancient block followed by the Tandilla Terrane (ages 2200 ± 100 My) which was joined through 1700 Ma. The Nico Perez Terrane displaced itself towards South generating the continental N10W mega shear fault Sarandi del Yi- Piriapolis towards 1250 My. Finally, the Arachania called continent made tangential collision from SE towards 525 Ma generating the ultramylonites band of the Sierra Ballena share zone. Each one of these terranes have totally different stratigraphy and lithological associations, and the chronological ages did not agree with the arrival of each one of the identified terranes

  7. Provenance study of the Castellanos and Migues formation: Santa Lucia basin, Uruguay

    International Nuclear Information System (INIS)

    A geochemical provenance study was conducted on the shales of Castellanos and Migues formations (Lower Cretaceous), which conform part of the filling of the Santa Lucía basin, southwest of Uruguay. The main features observed indicate that the shales are dominated by illite and smectite, subordinately appears kaolinite. Besides, feldspar, hematite and calcite are observed. Shale chemical composition is enriched in Cr and V with respect to the PAAS, NASC and Upper Continental Crust. From the application of the geochemical indexes of alteration (CIA, CIW and ICV) and of ternary diagrams ACNK and ACNK-FM, a low weathering degree is determined for the source areas, together with compositional immaturity. The use of other geochemical indexes and diagrams of geotectonic discrimination and source rock shows similar chemical composition with respect to the Río de la Plata Craton lithologies, which were established as the basin source rocks. It is concluded that the climatic conditions were arid to semi-arid with variable humidity at the time of the deposition. In addition, the establishment of Río de la Plata Craton as the basin source area suggests that the craton was not covered by Paleozoic sediments at the time of deposition of the studied units

    Full Text Available In this article we report the diet of a population of the hylid frogHyla pulchella from southeastern Uruguay. We collected the specimens in ponds, where we identified microenvironments defined by the invertebrate assemblage, during one year divided into two seasons (warm and cold. We taxonomically determined 10365 invertebrates belonging to 21 categories in the digestive tracts of frogs. Weestimated the diversity of the diet and alimentary preference according to microenvironments and seasons. We estimated the expected richness of both diet and prey availability using a null model based on the hypergeometric distribution. We performed Discriminant Analyses and Kruskal-Wallis tests to detect changes in prey availability among microenvironments and between seasons. The overall diet in terms of frequencies was composed primarily of arthropods (mainly Araneae, Diptera, Hymenoptera, and Coleoptera and in terms of volume, by larvae. The most relevantitems to study the microenvironmental and seasonal variation in the available preys were Araneae, Collembola, Homoptera, Hymenoptera, Diptera, Dictioptera, Lepidoptera, Coleoptera, and larvae. Based on the null model curves and preference indexes we inferred positive selection by larvae, Isopoda, Dictioptera, Lepidoptera, and Diptera, and negative selection by Collembola and Hymenoptera. The diversityof diet and the null model curves indicated that the diet changes among microenvironments and seasons. This frog may be considered as a middle generalist predator, with some selective behavior and a combined search strategy (active and sit-and-wait. We conclude that the knowledge about the availability of preys is a relevant tool for trophic studies.

  10. Vulnerability and hydrogeologic risk of SAG in the outcroupping zone of Rivera Uruguay

    International Nuclear Information System (INIS)

    The studied area belongs to the outcroupping zone of the Guarani Aquifer in the Department of Rivera, Uruguay. It comprises an approximate area of 2900 Km2. The outcropping Guarani Aquifer (AGa) is formed by two sections, an upper one corresponding to the Rivera Unit (UR) and a lower one corresponding to the Tacuarembo Unit (UT), both with vertical hydraulic continuity. The Rivera Unit is entirely represented by the homonymous formation and it consists of medium to fine sandstones with a mean effective porosity of 14% and mean Transmissivity of 88 m2/dia. The Tacuarembo Unit is constituted by fine to very fine sandstone levels interbedded with pelitic sandstone and shales. This unit behaves like unconfined aquifer in the upper section, where it contains the phreatic layer and it passes to semi-confined as the depth increases. The effective porosity is approximatelly of 9% and mean T 24 m2/dia. Chemically, both units are classified as calcicbicarbonated and magnesic-bicarbonated. To determine the vulnerability, it was applied the GOD method yielding high vulnerability for levels lower than 10m and moderate for levels of water larger than 10m. From the study of risk the conclusions are: high risk of groundwater contamination due to the lack of sewage systems and to the rubbish dump leakage. The industrial activity, cemeteries and mining activity represents moderated risks in most of the cases

  13. Tacuari formation (Nov. Nom.): Lithostratigraphy, facies, environment, age and geological significance (Cerro Largo - Uruguay)

    International Nuclear Information System (INIS)

    The definition of the Tacuari formation is proposed to group a set of glacial and fossiliferous siliciclastic rock deposited during the Upper proterozoic in the northeast of Uruguay. Up to this paper these lithologies were included in the San Gregorio formation (Carboniferous - Permian - Norte Basin). However, Leiosphaeridia tenuissima, L, minutissima, Myxcocooides distola, M, siderophila, Soldadophycus bossil and S. major were recorded in these rocks.This finded motivated the accomplishment of geological surveys that allowed to ferify the glacial origin of the Tacuari formation, to define its stratigraphic relationships and to corroborate its affectation by the Sierra Ballena shear zone. Two association of facies were recognized in the Tacuari formation: the base is represented by facies association A (outwash plains), characterized diamictites, sandostones and pelites; at the top, the facies association B (glaciomarine) includes a package of rhythmites with dropstones. On account of the tectonic setting, nature of sedimentation, age, and fossils, the definition of Tacuari formation constitutes a novel contribution to the regional evolutionary model of the Upper proterozoic. discussion of posible stratigraphc correlations with other neoproterozoic units of Western wondwana is also attempted

  14. Petrogenesis of early cretaceous silicic volcanism in SE Uruguay. The role of mantle and crustal sources

    International Nuclear Information System (INIS)

    Early Cretaceous (∼129 Ma) silicic rocks crop out in SE Uruguay between the Laguna Merin and Santa Lucia basins in the Lascano, Sierra Sao Miguel, Salamanca and Minas areas. They are mostly rhyolites with minor quartz-trachytes and are nearly contemporaneous with the Parana-Etendeka igneous province and with the first stages of South Atlantic Ocean opening. A strong geochemical variability (particularly evident from Rb/Nb, Nb/Y trace element ratios) and a wide range of Sr-Nd isotopic ratios (143Nd/144Nd(129)=0.51178-0.51209; 87Sr/86Sr(129)=0.70840-0.72417) characterize these rocks. Geochemistry allows to distinguish two compositional groups, corresponding to the north-eastern (Lascano and Sierra Sao Miguel, emplaced on the Neo-Proterozoic southern sector of the Dom Feliciano mobile belt) and south-eastern localities (Salamanca, Minas, emplaced on the much older (Archean) Nico Perez terrane or on the boundary between the Dom Feliciano and Nico Perez terranes). These compositional differences between the two groups are explained by variable mantle source and crust contributions. The origin of the silicic magmas is best explained by complex processes involving assimilation and fractional crystallization and mixing of a basaltic magma with upper crustal lithologies, for Lascano and Sierra Sao Miguel rhyolites. In the Salamanca and Minas rocks genesis, a stronger contribution from lower crust is indicated. (author)

    In this work, the antimicrobial activity of extracts of wood rotting higher Basidiomycetes mushrooms isolated from Eucalyptus plantations in Uruguay was studied using bacterial and fungal phytopathogens as targets. Fifty-one extracts from mycelia and growth broth were prepared from higher Basidiomycetes mushrooms, from which eight extracts (from Ganoderma resinaceum, Laetiporus sulphureus, Dictyopanus pusillus, and Bjerkandera adusta) showed antimicrobial activity against Xanthomonas vesicatoria, Aspergillus oryzae, Penicillium expansum, Botrytis cinerea, and Rhizopus stolonifer as assayed in the qualitative test. The minimum inhibitory concentration (MIC) for those fungal extracts was determined and the results showed that L. sulphureus deserved further study, with low MIC values against X. vesicatoria. The antimicrobial activity of L. sulphureus culture broth extracts grown under different culture conditions was evaluated against X. vesicatoria. From the results of these assays, larger-scale cultures for the production of the compound(s) with antimicrobial activity should be performed using malt extract broth, at pH 5, at 20°C and static culture conditions.

    Porcine Circovirus Type 2 (PCV2) is a worldwide distributed virus and is considered an important emerging pathogen related to several distinct disease syndromes in pigs. PCV2 strains are classified into three genotypes: PCV2a, with five subtypes (2A-2E), PCV2b with three subtypes (1A-1C) and PCV2c, only found in Denmark. Recently, several reports suggested the circulation of newly emerging PCV2b mutants (mPCV2b) isolated from pigs with PCVAD in cases of suspected vaccine failure. In this work, we report for the first time the identification of mPCV2b in pigs from Uruguay, providing an additional evidence of a global circulation. Complete genome characterization and phylogenetic analysis reveal that Uruguayan strains, as well as mPCV2b previously reported are closely related to other sequences already classified as PCV2b-1C. Furthermore, results showed that mPCV2b presented different genetic markers in the capsid protein compared with classical PCV2a/b strains. Further investigation about antigenic shift of the mPCV2b strains including the Uruguayan isolates is needed. PMID:26004195

  19. Reference evapotranspiration estimation from class A pan in the northwest of Uruguay

    International Nuclear Information System (INIS)

    Efficient water management in agriculture requires accurate estimation of the evapotranspiration. The difficulty in obtaining records of all the variables needed to estimate reference evapotranspiration (E To) by the model proposed by Penman-Manhattan-FAO56 (Allen et al., 1998), leads to the use of alternative methods, such as pan evaporation class A (E o), which requires regional calibrations for successful implementation. This paper compares four methods for estimating the adjustment coefficient (Kp) of E o over ETo: i) the procedure proposed by Snyder (1992); i i) by Allen et al. (1998); III) by Pu ppo and Gar cia Petillo (2009); and i v) the Kp-combined obtained through the regression coefficient of E o to ETo for the region under study. The regression coefficient values of E o over ETo change slightly according to the average interval used, being 0.77, 0.75 and 0.73 for the monthly interval, de-iced (10 days) and weekly. The estimation error decreases as we average at longer intervals. The procedure i) significantly overestimated ETo, while i i) underestimated both, with a mean absolute error of 0.49 and 0.86 mm respectively, while in III) is 0.32 and the i v ) is 0.37 mm. Procedures III) and i v) with constant values of Kp had the best performance for the northwestern region of Uruguay

A total of 143 frogs were collected, measured, sexed, and dissected, to assess stomach contents. The anurans were grouped into three age classes and four categories (considering sex and capture date. The trophic amplitude for each age class and sex-season category was quantified using Shannon-Weaver Index, and the trophic niche overlap between ages and categories by using the Pianka Index. Comparisons among treatments were made by G-tests. The most important prey items were coleopterans (IRI = 2547, and significant correlations were found between predator and prey sizes. The major differences on diet composition were found between extreme age classes (froglets and adults. Significant differences were also detected between sexes in the cold season but not in the warm season. Any of these changes in diet may be related with the availability of prey.

    2006-09-01

    A Permian bentonite deposit at Melo, Uruguay is composed of a calcite-cemented sandstone containing clay pseudomorphs of glass shards (0-0.50 m) overlying a pink massive clay deposit (0.50-2.10 m). The massive bed is composed of two layers containing quartz and smectite or pure smectite respectively. The smectite is remarkably homogeneous throughout the profile: it is a complex mixed layer composed of three layer types whose expandability with ethylene glycol (2EG 1EG or 0EG sheets in the interlayer zone which correspond to low-, medium- and high-charge layers respectively) varies with the cation saturating the interlayer zone. The smectite homogeneity through the profile is the signature of an early alteration process in a lagoonal water which was over saturated with respect to calcite. Compaction during burial has made the bentonite bed a K-depleted closed system in which diagenetic illitization was inhibited. Variations in major, REE and minor element abundances throughout the massive clay deposit suggest that it originated from two successive ash falls. The incompatible element abundances are consistent with that of a volcanic glass fractionated from a rhyolite magma formed in a subduction/collision geological context. PMID:16936941

Para responder estas interrogantes, se establece que la disímil ruta seguida en ambos países, en términos de gobernabilidad democrática, se debe a una distinta configuración institucional que se divisa en la larga duración y, más específicamente, en la construcción del modelo económico que hizo eclosiónThis article tries to understand why there was a different response to the latest economic crises that took place in the years 2001 and 2002 in Argentina and Uruguay. Why was there not a similar reaction in terms of democratic governability? Why did the crises affect the legitimacy of the Argentine party system and not generate the same effect in Uruguay? Why did it force the resignation of the Argentine president and not have the same effect in Uruguay? In order to answer these questions, this article assumes that the different paths followed by both countries during the crises, in terms of democratic governability, can be explained by the different institutional configurations developed through each of their political histories and, more specifically, in the construction of the economic model which collapsed in 2001 and 2002

    Full Text Available Em Amarantina, distrito de Ouro Preto, encontram-se rochas ultramáficas expostas em duas áreas com cerca de 500 m² cada. As rochas afloram no Complexo do Bação, que é o embasamento gnáissico do greenstone belt Rio das Velhas, na porção central do Quadrilátero Ferrífero (QF. O interesse no estudo petrogenético desses corpos deve-se à preservação parcial de minerais ígneos, ausentes na maior parte das rochas ultramáficas totalmente metamorfizadas do QF. Entre essas rochas, destacam-se os esteatitos e os serpentinitos, devido a sua importância econômica. As rochas ultramáficas de Amarantina possuem textura equigranular, fato que as caracteriza como tendo origem plutônica, isto é, trata-se de metaperidotitos. Possuem grãos maiores de olivina, piroxênio e espinélio da rocha ígnea original distribuídos em matriz metamórfica fina com talco, serpentinas, cloritas, anfibólios e minerais opacos. Escassas arita (NiSbAs e breithauptita (NiSb foram formadas a partir de pentlandita durante o metamorfismo associado a hidrotermalismo. A comparação da composição química com a de um metakomatiito com textura spinifex do QF, bem como com rochas komatitiiticas de outras partes do mundo, mostra que os metaperidotitos são, quimicamente, semelhantes aos komatiitos não-desfalcados em alumínio. Portanto é provável que as rochas ultramáficas estudadas correspondam à porção plutônica do magmatismo komatitiitico do Grupo Nova Lima, que é a unidade basal do greenstone belt Rio das Velhas.In Amarantina, district of Ouro Preto (State of Minas Gerais, Brazil, ultramafic rock exposures are found along two areas of about 500 m² each.

    Rickettsia parkeri rickettsiosis is a vector-borne zoonosis that occurs in some countries of the American continent. Following the first description and determination of the pathogenicity to humans in 2004 in USA, this bacterium has been reported in several South American countries. Human cases have been diagnosed in both Uruguay and Argentina in the past years. This study consisted in a serosurvey of 1000 domestic dogs living in the endemic area of rickettsiosis in Uruguay, where Amblyomma triste is the tick vector. Sera were analyzed by Indirect Immunofluorescence Assay (IFA), against antigens of three different rickettsial species: R. rhipicephali, R. felis and R. parkeri. It was determined that 20.3% of the dogs had antibodies that reacted to at least one of the three species tested, taking as cut off ≥64 titers. Furthermore, 140 of the seropositive dogs (14%) had a titer at least 4 times higher to R. parkeri than those of any of the other species, thus, it was considered that the immune response was stimulated by that species in particular. This is the first serological survey in primary hosts for adults of A. triste in Uruguay, and therefore the first prevalence values are reported. Adult A. triste ticks collected from the environment as well as from dogs were analyzed by PCR in order to confirm the current circulation of the agent in the area. In this matter, two out of 28 ticks from dogs, and 3 out of 53 ticks from the environment were positive, and the corresponding sequence analysis revealed 100% similarity with R. parkeri strain maculatum.

    Full Text Available Between 2009 and 2011 the Inter-American Court of Human Rights issued two convictions to Mexico and Uruguay. These cases may be regarded as paradigmatic of the repressive legacy of the seventies and eighties. Although both States have taken different routes of their political regimes, the crimes may come to be considered similar. Political contexts in which it has been discussed the legacy of human rights violations have differences. In this article we look at aspects of the pathways leading to the main judgments and official reactions to those decisions, and explores the reasons for such behavior.

    Nosema ceranae is one of the most prevalent pathogens in Apis mellifera and has recently been found in multiple host species including several species of bumblebees. Prevalence and infection intensity of N. ceranae was determined in two species of native bumblebees from Uruguay. Nosema ceranae was the only microsporidia identified and mean prevalence was 72% in Bombus atratus and 63% in Bombus bellicosus, values much higher than those reported elsewhere. The presence of this pathogen in bumblebees may be threatening not only for bumblebee populations, but also to the rest of the native pollinator community and to honeybees. PMID:26248064

  1. Gas hydrates:estimation of the gas potential, from reflection seismic data in the continental shelf of Uruguay

    International Nuclear Information System (INIS)

    The uruguayan continental shelf shows geophysical indicators of gas hydrates in the Oriental del Plata, Pelotas and Punta del Este basin. The aim of this work is to present the potential presence of gas at the continental shelf in Uruguay and to evaluate the possibility of exploration of unconventional hydrocarbon plays. Analysis of the seismic surface based on regional and stratgigraphic information that proceeded from previous hydrocarbon exploration in the area have been used to estimatge resources of gas hydrates. Gas hydrates accumulation was mapped using characteristic reflectors and amplitude anomalies of seismic lines (BSR). Its quantity was estimated on this basis in about 86 TCF.

  6. Evaluation of a seasonal-breeding artificial insemination programme in Uruguay using milk progesterone radioimmunoassay

    International Nuclear Information System (INIS)

    To evaluate artificial insemination (AI) services and reproductive efficiency in dairy herds in Uruguay two surveys were conducted in 1995 and 1996. The 1995 survey was done in 10 dairy farms of 3 regions on 696 lactating Holstein cows. The 1996 survey was done in 5 dairy farms in one region and included 768 cows. Precision of oestrus detection and efficiency of AI services were determined by milk progesterone samples taken at days 0, 10 and 23 after breeding and by analysis of the records. In 1995 and 1996, the intervals from calving to first service were 123 and 101 days, and to conception were 158 and 134 days, respectively. Parity, body weight and body condition at calving influenced these parameters, but not body weight or body condition at breeding nor milk production. Accuracy of pregnancy diagnosis by milk progesterone was 70.4%. Heat detection rate was 37.5% and pregnancy rate was 15.6%. In 1997 a second study was done to determine the factors affecting reproductive efficiency in a seasonal breeding AI programme in 328 lactating cows on 3 dairy farms. Milk progesterone measurement revealed that 12.5% of the cows were anoestrous at the beginning of the season and remained so during the trial. The category mostly affected were first-calf heifers (82%). Also, 8.5% of the cows cycling were never reported in heat and this was influenced by farm. Oestrus detection efficiency for cows determined to be cycling by progesterone profiles was evaluated in three periods of 21 days and overall efficiency was 46.9%. Main factor affecting it was farm, with an effect of parity (67.8% in mature cows and 33.2% in first-calf heifers) but no effect of days postpartum. Mean interval from the beginning of the breeding season to first service was 27.4 days, again with a strong farm variation but no effect of parity or days postpartum. In an attempt to improve reproductive efficiency in lactating dairy cows, a treatment protocol was designed, where 414 cows in two herds were

    The stocks of Southern sea lions (Otaria flavescens, SSL) and South American fur seals (SAFS) that breed on coastal islands of Uruguay constitute the most important focal concentration of pinnipeds in South America, with a significant increase in SAFS and a steady decrease of SSL over the past decades. Because females are a key element of population dynamics and no information exists on the post-breeding pup rearing period, we studied the foraging patterns of SSL females in the La Plata River Estuary (LPRE) during mid and late lactation (late austral autumn and winter), analyzing the foraging performance, geographic coverage and ontogenetic differences in foraging strategies for a period of 1-5 months. At-sea movements of 22 SSL females (6 subadults and 16 adults) from Isla de Lobos (IL, 35°01'28"S-54°52'59"W, Uruguay) were monitored using satellite transmitters (SPOT4, SPOT5 and STDR-S16, Wildlife Computers) in 2007 and 2010.

One hundred and eighty three foraging trips (FT) were recorded with no significant differences (pSpider) distance (100.2±41.40 km) and transit speed (1.1±1.04 m s-1). SSL showed directional fidelity to foraging sites, indicated by high mean vector (r) values (0.74±0.14) calculated from FT mean bearings. Kernel ranges for 50% and 95% of all FT locations were 5420 km2 and 36,222 km2, respectively, and the extension of the foraging areas appeared to be influenced by a combination of bathymetry and ecological boundaries within LPRE. Regardless of their reproductive condition, females showed a strong fidelity to IL, and their foraging activity was

Sampling was conducted in the lotic region of the river in two sites between the dams' reservoirs: Uruguay (main river and Ligeiro (tributary. Sampling included nine consecutive reproductive periods (RP spanning the period from 2001 to 2010 and was conducted at night on the water surface using cylindrical-conical plankton nets (0.5 mm mesh; environmental variables were also recorded. The spawning of the migratory species Salminus brasiliensis, Prochilodus lineatus, and Steindachneridion scriptum was registered: S. brasiliensis and P. lineatus spawned in the tributary river at the end of spring/beginning of summer, during flooding and during periods of high water temperature. Steindachneridion scriptum spawned in the main river at the beginning of spring. The study showed that S. brasiliensis, P. lineatus, and S. scriptum are able to spawn in small lotic river stretches within two reservoirs, but only under very specific and not common environmental conditions.Este estudo verificou a presença de desova de peixes migradores entre os reservatórios das Usinas Hidrelétricas de Machadinho e Itá (alto rio Uruguai, Brasil, e sua relação com as variáveis ambientais.

    Most studies of sandy beach macrofauna have been restricted to semiterrestrial species and do not include insects when providing species richness and abundance estimates. Particularly, spatio-temporal patterns of community structure of the entomofauna inhabiting these ecosystems have been scarcely documented. This study assessed spatio-temporal distributional patterns of the night active entomofauna on a beach-dune system of Uruguay, including variations in species richness, abundance and diversity, and their relationship with environmental factors. A deconstructive taxonomic analysis was also performed, considering richness and abundance patterns separately for the most abundant insect Orders (Hymenoptera and Coleoptera) to better understand the factors which drive their patterns. We found clear temporal and across-shore patterns in the insect community inhabiting a land-ocean interface, which matched spatiotemporal variations in the environment. Abundance and species richness were highest in spring and summer, concurrently with high temperatures and low values of sediment moisture and compaction. Multivariate ordinations showed two well-defined species groups, which separated summer, autumn and spring samples from winter ones. Generalized Linear Models allowed us to describe a clear segregation in space of the most important orders of the insect community, with specific preferences for the terrestrial (Hymenoptera) and beach (Coleoptera) fringes. Hymenoptera preferred the dune zone, characterized by high elevation and low sand moisture and compaction levels, whereas Coleoptera preferred gentle slopes and fine and humid sands of the beach. Our results suggest that beach and dune ecosystems operate as two separate components in regard to their physical and biological features. The high values of species richness and abundance of insects reveal that this group has a more significant ecological role than that originally considered so far in sandy beach ecology.

Realiza una estimación cuantitativa de alguna de sus características y problemas, a partir de fuentes de datos distintas y en especial el Censo Nacional en Psicología del año 2014 y las Bases de Recursos Humanos del Ministerio de Salud Pública. Se fundamenta la necesidad de mayores y mejores estudios, teniendo en cuenta la inserción profesional de los psicólogos en el contexto del cambio de modelo de atención, impulsado por la reforma de la salud. Observa el incremento de los inscritos y graduados de estudios de grado, en términos absolutos y relativos respecto a las otras carreras universitarias. La existencia de un alto número de psicólogos ubica al país posiblemente en el primer lugar, en relación a su población, con un porcentaje mayoritariamente femenino, alta presencia de egresados recientes, y residencia concentrada en zona metropolitana. Aún con mejoras en los últimos años, los datos muestran aún una débil inserción en el sistema de salud, lo que es consistente con la percepción de una respuesta insuficiente a las necesidades de atención psicológica. Se requieren por tanto, avanzar en las investigaciones que generen insumos para el diseño de políticas de recursos humanos en salud.

The concentration that inhibits 90% (MIC90 of the analysed strains reported in micrograms per millilitre, for Staphylococcus aureus were > 8, 8, ≤ 0.5, ≤ 4, ≤ 1, ≤ 0.5, > 64, ≤ 0.25, 0.5, ≤ 1 and ≤ 1 to penicillin, ampicillin, oxacillin, cephalotin, gentamicin, erythromycin, oxitetracycline, enrofloxacin, trimethoprim/sulfamethoxazole, neomycin, and clindamycin, respectively. Coagulase-negative staphylococci (CNS had different values for penicillin (4 and ampicillin (2, while the other antimicrobial agents had the same MIC90 values as reported for S. aureus. The MIC90 values for streptococci were 0.12, 0.25, ≤ 4, 16, ≤ 0.25, 0.5, 0.25 for penicillin, ampicillin, cephalotin, gentamicin, erythromycin, oxytetracycline and trimethoprim-sulfamethoxazole, whereas MIC90 for enterococci were 4, 4, 4, ≤ 0.5, 2, > 8 for penicillin, ampicillin, gentamicin, erythromycin, oxytetracycline and trimethoprim-sulfamethoxazole, respectively. Of 336 strains of S. aureus, 160 (47.6% were resistant to penicillin. For 41 CNS strains, 10 (27% presented penicillin-resistance. All the streptococcal strains were susceptible to penicillin, while 3 (7% of the 43 enteroccocal strains were resistant. Non significant statistical differences were found between the results obtained by ADDM and broth micro-dilution for classifying bacterial isolates as susceptible or resistant according to the National Committee of Clinical Laboratory Standards.

    Full Text Available El artículo analiza la situación actual de los archivos en Uruguay en relación a las leyes de Acceso a la Información Pública y de Sistema Nacional de Archivos, normativas que surge cuando el Estado uruguayo inicia una fase de reordenación de su gestión promoviendo cambios que fomentan la democratización y la eficiencia, a la vez que anulan la opacidad y extrema reserva en su administración. Se analiza cómo los profesionales archivólogos estuvieron estrechamente involucrados en el proceso de gestación de ambas leyes, dando inicio a una etapa de consecución de fuertes voluntades políticas que apoyaran los proyectos, convencidos que la premisa evidente del Derecho de Acceso es que el documento al que se pretenda acceder exista y sea recuperable. Se estudia como la coexistencia de ambas normas implicaban un cambio cultural, una evolución en el comportamiento de las organizaciones que no acompañó a la puesta en marcha de los instrumentos legales. Se concluye que el Derecho de Acceso a la Información Pública está basado en el principio fundamental de transparencia de los Órganos del Estado, por lo que no es de extrañar que una ley que obliga a brindar información tenga el riesgo de devenir en letra muerta. El Archivo debe ser “condición” administrativa, lo que exige una nueva dimensión de ellos y de sus profesionales dentro de los organismos del Estado, de forma tal que se conviertan en una inmejorable herramienta para el cumplimiento de los objetivos de la Ley de Derecho de Acceso a la Información Pública.

    In many areas of Uruguay groundwater is the only source of water for human consumption and for industrial-agricultural economic activities. Traditionally considered as a safe source, due to the "natural filter" that occurs in porous media, groundwater is commonly used without any treatment. The Uruguayan law requires bacteriological analysis for most water uses, but virological analyses are not mentioned in the legislation. In the Salto district, where groundwater is used for human consumption and for agricultural activities, bacterial contamination has been detected in several wells but no viruses analysis have been performed. The Republic University (UDELAR), with the support of the National Agency for Research and Innovation (ANII), is studying the incidence of virus in groundwater on an intensive agriculture area of the Salto district. In this area water is pumped from the "Salto Aquifer", a free sedimentary aquifer. Below this sedimentary deposit is the "Arapey" basaltic formation, which is also exploited for water productions on its fractured zones. A screening campaign has been performed searching for bacterial and viral contamination. Total and fecal coliforms have been found on several wells and Rotavirus and Adenovirus have been detected. A subgroup of the screening wells has been selected for an annual survey. On this subgroup, besides bacteria and viruses analysis, a standard physical and chemical characterization was performed. Results show a significant seasonal variation on microbiological contamination. In addition to field studies, rotavirus circulation experiments on columns are being performed. The objective of this experiments is to determinate the parameters that control virus transport in porous media. The results of the study are expected to provide an insight into the impacts of groundwater on Salto's viral gastroenterocolitis outbreaks.

Of 130 snails exposed to the SJ2 strain, originally infective to Biomphalaria tenagophila, 30 became infected (23%. The prepatent (precercaria period ranged from 35 to 65 days. The cercarial output was irregular, following no definite pattern, varying from 138 to 76,075 per snail (daily average 4.3 to 447.5 and ending up with death. Three specimens that died, without having shed cercarie, on days 69 (2 and 80 after exposure to miracidia, had developing secondary sporocysts in their tissues, justifying the prospect of a longer precercarial period in these cases.

No cercarie were produced by any of the Espinilar snails exposed to miracidia of the BH2 strain, originally infective to Biomphalaria glabrata. Four specimens showed each a primary sporocyst in one tentacle, which disappeared between 15 and 25 days post-exposure, and two others died with immature, very slender sporocysts in their tissues on days 36 and 54. In a control group of 100 B. glabrata exposed to BH2 miracidia, 94 shed cercariae (94% and 6 remained negative. Calculation of Frandsen's (1979a, b TCP/100 index shows that "Espinillar Biomphalaria-SJ2 S. mansoni" is a vector-parasite "compatible" combination.

No primeiro experimento bovinos confinados ingeriram, durante 6 meses, quantidades variáveis (63 e 128g/dia de fosfato de Tapira contendo 1.3% de flúor. No segundo experimento, bovinos em pastos de Brachiaria decumbens ingeriram, durante 33 meses, misturas minerais contendo diferentes níveis de fosfato de rocha de Tapira. No terceiro experimento, novilhas com idade inicial média de 14 meses ingeriram mistura mineral com fosfato de Tapira até a quinta lactação inclusivamente. Através de exames histológicos, morfométricos e microrradiográficos das amostras de costelas, não se observaram alterações da normalidade óssea, bem como não foram registradas diferenças entre amostras provenientes de diferentes tratamentos.

Los ítems más consumidos por C. decemmaculatus fueron zooplancton, perifiton, fitoplancton y detritos; la dieta de J. multidentata incluyó zooplancton, insectos, crustáceos y peces juveniles. Estos resultados sugieren que ambas especies pueden actuar como planctívoros facultativos. La comunidad de peces de este lago se caracteriza por la dominancia de C. decemmaculatus y J. multidentata. Bajo esta condición, la depredación sobre el zooplancton de gran tamaño podría indirectamente estar contribuyendo a una alta abundancia de fitoplancton y una baja transparencia del agua.Diet of Cnesterodon decemmaculatus (Jenyns, 1842 and Jenynsia multidentata (Jenyns, 1842 were analysed in Lake Rodó, an urban hypertrophic lake from Montevideo, Uruguay.

    Full Text Available Uruguay es un país que desde 2005 ha realizado una política activa de control del tabaco. Sin embargo, la evolución de la demanda del total de productos de tabaco muestra un descenso insignificante en los últimos cinco años, lo que es contrario a lo esperado. La hipótesis es que el fuerte crecimiento del ingreso de los hogares unido a una elasticidad-ingreso de la demanda de cigarrillos cercana a 1 fue uno de los factores que contrarrestó el aumento real en los precios vía impuestos. El aumento en el ingreso de los hogares fue de 36% en términos reales en el periodo 2005-2009 debido a la fuerte recuperación luego de la crisis del año 2002. Por otro lado, un segundo factor explicativo importante de la demanda de cigarrillos en el Uruguay es la sustituibilidad entre cigarrillos y tabaco de armar. El impuesto y precio del tabaco de armar sigue siendo sustancialmente más bajo que el del cigarrillo, de forma que en los últimos años la cantidad demandada de tabaco de armar ha subido. El trabajo consistió entonces en revisitar un estudio de demanda realizado en 2004 por los autores y volver a estimar una función demanda de los dos productos principales de tabaco en el Uruguay (cigarrillos y tabaco de armar, lo que permite estimar las elasticidades precio, ingreso y cruzadas. A partir de estas estimaciones se realiza un ejercicio de simular alternativas de incrementos de impuestos con lo que se evalúa qué aumentos son necesarios para realmente impactar sobre la demanda en un escenario de crecimiento del ingreso de los hogares moderado de 2.5% anual y alto de 5% anual. Se confirma que se necesitan aumentos de impuestos muy superiores a los verificados en el último quinquenio.Uruguay, a country with a solid tobacco control policy since 2005 shows, contrary to expectations, an insignificant decrease in total tobacco products' sales in the last five years.

A região de estudo compreende parte da área do município de Carlos Barbosa, localizado na região nordeste do estado do Rio Grande do Sul. O estudo foi desenvolvido a partir do inventário e cadastramento de poços tubulares existentes na região, do levantamento e interpretação de dados geológicos e hidrogeológicos, além da coleta e análise de amostras de água de poços tubulares que estão em funcionamento e são utilizados pela companhia de abastecimento CORSAN. Os resultados obtidos permitiram evidenciar que a maioria dos poços apresenta profundidade de até 150 metros com vazões médias que variam de 5 a 20 m³ h-1 , localizados em zonas de média e alta densidade de fraturas, as quais possuem orientação preferencial para noroeste. Quanto à hidroquímica, as águas que circulam por esses aquíferos são do tipo bicarbonatadas cálcicas ou magnesianas, predominando as águas bicarbonatadas mistas e cálcicas, apresentando pequenas variações quanto à concentração dos íons e suas razões iônicas. Essas características hidroquímicas são típicas de águas que circulam por estruturas de rochas vulcânicas ácidas e indicam um baixo tempo de residência, sendo as concentrações variáveis com as profundidades das entradas da água

    The Piedras de Afilar Formation crops out in the southeast part of Uruguay, forming part of the Tandilia Terrane (sensu Bossi et al. 2005). Pamoukaghlian et al. (2006) and Gaucher et al. (2008) have published δ13C, δ18O and U/Pb SHRIMP results, which indicate a Neoproterozoic age for this formation. The palaeoenvironment has been defined as a shallow marine platform based on the presence of interference ripples, hummocky and mega-hummocky cross-stratification. X-ray diffraction (XRD) analyses help to better constrain the palaeoenvironment: the presence of chlorite/smectite found in black shales, suggest a reducing environment, and abundant illite indicates a cold to temperate climate. Provenance studies have been undertaken that utilise a combination of detailed palaeocurrent measurements, petrographic descriptions, XRD analyses, and geochemical isotopic analyses, including U/Pb SHRIMP determinations. Mineral compositional diagrams for sandstones suggest a stable cratonic provenance. Palaeocurrents are mainly from the NNE, indicating a provenance from the cratonic areas of the Tandilia Terrane. The illite crystal index indicates diagenetic to low-metamorphic conditions for the sequence; this is important to confirm that the identified minerals are authigenic. Clay minerals identified by XRD analysis of sandstones from the siliciclastic member are illite (80 - 90%), kaolinite (5 - 10%), and chlorite (5 - 10%). This is consistent with a provenance from the cratonic areas (quartz-feldspar dominated rock types). Isotopic analyses have been undertaken to provide better constraints on the tectonic setting. U/Pb SHRIMP ages for the youngest zircons are 990 Ma (Gaucher et al. 2008), and the basal granite (Granito de la Paz) is 2056 ± 11 Ma (Hartmann et al. 2001), suggesting a provenance from the Archaean basement for the Piedras de Afilar Formation, like its counterparts in the Rio de la Plata Craton.

In this paper, the main advances in the knowledge of marine life in these areas (the known are reviewed in order to discuss future lines of research (the unknown. Information has been separately analysed for the plankton, nekton, and benthos in each of 3 areas-the littoral, the shelfs and the "open ocean". Current knowledge of marine life is uneven among the groups and areas. In the case of the plankton, research has concentrated on the near-shore waters and focused on taxonomy and distribution. Little is known about the responses of organisms to environmental variability and about biological processes. The nekton of coastal and estuarine areas is better known, but, with shelf and slope assemblages, research has focused on exploited species. The main unknowns for the nekton are how trophodynamics, reproduction, and recruitment processes are linked to environmental variability and the effect of fisheries on community structure. Littoral benthos, in particular the macroinfauna of sandy beaches, is much better studied and spatial patterns of community distribution have been identified at different scales and in relation to environmental variables. Also, at the population level, there is information about distribution, responses to disturbances, dynamics, and the roles of biotic and abiotic factors in modulating population variability. Information is mainly lacking for the sub-tidal fringe and regarding the macro-ecology of population dynamics, the dispersive abilities of larval phases, and the effects of toxic blooms on suspension feeders. Knowledge of the benthos of estuaries and more so of the shelf and slope environments is rather scarce. For the latter two, faunal inventories are far from complete. Topics identified for future research include taxonomy, macro-scale community structure and its

    Full Text Available Este artículo trata sobre las reformas judiciales en Sudamérica, durante los años 90. Muestra que tanto en el caso de la Argentina como en el de Chile, las reformas a los códigos de procedimiento estuvieron motivadas por tres factores centrales, vinculados con el doble pro­ceso de democratización y liberalización económica: i la preocupación con la violación de dere­chos humanos que provenía de los pasados regímenes autoritarios; ii el deseo de crear ambientes legales estables tanto para los derechos de propiedad como para la inversión extranjera; y iii la preocupación pública en torno a tasas de criminalidad cada vez más altas. Las reformas consti­tucionales que afectaron a las Cortes Supremas tanto en la Argentina como en Chile estuvieron vinculadas por razones estrictamente auto-interesadas. En última instancia, estas reformas fue­ron el resultado de compromisos políticos entre la izquierda y la derecha en respuesta a parti­culares eventos nacionales. En Uruguay, los frustrados intentos por desarrollar reformas en el código de procedimientos criminales y en el ámbito de la Corte Suprema pueden atribuirse a una combinación de falta de voluntad política, la carencia de apoyo a las mismas reformas judi­ciales, y una falta de recursos económicos. Notablemente, el análisis muestra que en ninguno de los tres países examinados las agencias internacionales han jugado un rol significativo a la hora de promover reformas u ofrecer asistencia financiera o técnica en favor de los cambios en los códigos de procedimiento o en la organización de las Cortes Supremas. Ello sugiere que estos dos tipos de reformas judiciales en el Cono Sur han sido motivados, ante todo, a partir de deman­das nacionales, y no a partir de una presión internacional –lo que muestra una diferencia impor­tante en el contexto de reformas que distinguió a estos tres países latinoamericanos–, y el que se dio en otros países de la región.

Un enfoque moderno de adaptación para enfrentar circunstancias climáticas adversas consiste en la formulación e implementación de medidas anticipatorias comúnmente denominadas estrategias de "gestión de riesgos". Para el desarrollo de tales medidas es un requisito básico el disponer de información confiable y frecuentemente actualizada del uso actual de la tierra, ubicación de los distintos rubros de producción y monitoreo frecuente de estas y otras variables. El objetivo del trabajo fue explorar la utilización de imágenes de satélites Landsat para ubicar y estimar áreas ocupadas por cultivos de invierno en la región de producción agrícola ganadera de Uruguay comprendida en los departamentos de Colonia, Soriano y Río Negro. Para realizar la estimación de la superficie ocupada por cultivos de invierno se utilizaron seis imágenes capturadas por el satélite Landsat 5 TM a las que se le practicaron clasificaciones supervisadas y posteriormente se aplicaron modelos para realizar un análisis multi-temporal del área de estudio, utilizando el software ERDAS Imagine. La estimación realizada en base al procesamiento de las imágenes de satélite reflejó en gran medida los resultados del Censo General Agropecuario del año 2000. Estos resultados permiten concluir que la utilización de la percepción remota con imágenes de satélite se presenta como una herramienta de gran potencial y utilidad para la determinación de áreas cultivadas, así como para el mapeo y monitoreo del uso de la tierra en Uruguay, contribuyendo a la preservación de los recursos naturales y los ecosistemas.One of the most important factors of risk in agricultural production consists of adverse climate events

    Full Text Available Los bosques del norte de Uruguay sufren de procesos de transformación del territorio y degradación, actualmente existe escasa información sobre la estructura y composición florística de las comunidades arbóreas que sirva como base para estudiar su dinámica. Se analizó la distribución, la composición arbórea y el manejo silvícola de los bosques de la región de Rivera, Uruguay. El área de estudio comprende 33 000 ha delimitadas mediante 2 criterios, uno natural (cuenca hidrológica y otro socioeconómico (ciudad de referencia. La información proveniente de inventarios florísticos y encuestas a productores fue ingresada a un sistema de información geográfica. Los bosques se agruparon de acuerdo al gradiente hídrico asociado con curvas de nivel. La superficie de los bosques ocupa el 13.9% del área de estudio (región de Rivera, cifra que triplica la superficie de bosques existente a nivel nacional. Se registraron 60 especies leñosas. Las familias con mayor frecuencia fueron Anacardiaceae (26.5% y Euphorbiaceae (14.7%. Las Anacardiaceae son más frecuentes en los bosques subxerófilos y las Euphorbiaceae en los bosques hidrófilos. Todos los bosques son vulnerables debido a la mayor importancia que se concede a la ganadería, sin que exista un manejo integrado de los bosques que contemple la multifuncionalidad de usos (silvicultura y ganadería. Los bosques cercanos a la ciudad están más degradados debido a la presencia de especies exóticas.The northern region of Uruguay undergoes land transformation processes, and degradation of native forest. The existing information on the structure and floristic composition of the forests in that region, as a basis for studies about dynamics, is scarce. Species distribution, floristic composition (wooden species and forest management, was assessed in the Rivera Region, Uruguay. The study area (33 000 ha was delimited by 2 simultaneous and complementary approaches, the first one natural

    Full Text Available Natural grasslands in the basaltic region of Uruguay are threatened by an increase in stocking rates and changes in land use. To assess the effect of grazing intensification, plant functional types are proposed as simple tools to aid the monitoring and management of vegetation. In the present study we evaluated the effect of stocking rate increase at community level taking into account plant traits of 23 dominant perennial grass species. In order to identify plant functional types, we determined the grazing response in an experiment with two wethers stocking rates (0.78 and 1.56 livestock units ha-1 quantifying species cover and traits values. Leaf dry matter content (LDMC and specific leaf area (SLA were the traits that best described the perennial grasses response to the stocking rate increase and therefore are suggested to be used as functional markers. Three functional types were identified. Low stocking rates were related to functional type A (tall, warm season species with low SLA and high LDMC and functional type B (tall, cool-season species, with intermediate levels of leaf traits. On the other hand, high stocking rate encouraged functional type C (prostrate, warm season species, with high SLA and low LDMC. The classification of a highly diverse community into three functional types and the selection of traits as functional markers candidates is an innovative approach to develop simple and general methods to diagnosis the state of basaltic grasslands in Uruguay and to advise on its management.Las praderas naturales de la region bas áltica de Uruguay están amenazadas por el incremento de la carga animal y cambios en el uso del suelo. Para evaluar el efecto del pastoreo se han propuesto los grupos funcionales como una herramienta simple para el monitoreo y manejo de la vegetación. El presente estudio evaluó el efecto del incremento de la carga animal considerando rasgos de 23 especies de gramineas perennes dominantes. Para identificar

    Full Text Available El propósito de este trabajo es analizar la relación ideas-pensamiento-política en Argentina, Brasil, Chile y Uruguay en el período que abarca las décadas de 1950 y 1960. En primer lugar, se reconstruyen los principales debates de la CEPAL de los tempranos años cincuenta y su repercusión en los distintos proyectos y alternativas políticas de la época. En segundo lugar, se analiza cómo el triunfo de la Revolución Cubana obligó a revisar esos mismos problemas latinoamericanos, abriendo un nuevo escenario de alternativas políticas para las izquierdas y para las derechas. El estudio propone reubicar "revolución" y "violencia", tópicos muy propios de la década de 1960, en un mapa integral de circulación de ideas que comenzó a conformarse en la coyuntura crítica de los 1950.This paper intends to analyze the relationship between politics, ideas and beliefs in Argentina, Brazil, Chile and Uruguay during the period 1950-1960. First, we reconstruct the main debates at CEPAL in the early 1950s and their repercussion on the distinct projects and political alternatives at that time. Second, we analyze how the success of the Cuban Revolution made it necessary to revise these same problems in Latin America, opening the door to a new scenario of political alternatives for the left- and right-wing. The study proposes reconsidering the position of "revolution" and "violence", topics that were highly characteristic of the 1960s, on an integral map of ideas that began to take shape in the critical instance of the 1950s.

    Full Text Available La resistencia política al gobierno por parte del soberano, puede expresarse de varias formas. Éstas varían según el grado en que erosionan la legitimidad del sistema, aplican soluciones previstas constitucionalmente y se articulan con las instituciones políticas. Al mismo tiempo, pueden tener motivaciones u objetivos diferentes, que van desde el desacato a alguna medida de gobierno, hasta su remoción total. Este artículo analiza una de las formas más institucionalizadas de la resistencia a un gobierno por parte del soberano: el uso de medidas de democracia directa para alterar un curso de acción del mismo, que va contra las preferencias ciudadanas. En particular, el artículo analiza el uso del recurso de referéndum en Uruguay, desde la transición democrática al presente (1985-2003.The widespread political resistance to the government took several different ways. Such resistances may include legitimate or non-legitimate approaches, within or outside the Constitution, involving or not the representative political institutions. At the same time, these processes may pursue different objectives which include from civil disobedience up to the government ousting. This article examines the most common institutionalized ways of civil resistance to the government: the use of direct democracy to change the unpopular government’s policies. Specifically, this article examines the use of referendum in Uruguay, since the transition to democracy in 1985 to date.

    Full Text Available This article analyzes the political imaginaries in the official discourses about the public administration reforms in Argentina, Chile and Uruguay, during the nineties. The new management methods are based on technical concepts that do not signify by themselves. To acquire effective meaning, these concepts depend on systems of ideas about the significance of the State and democracy, settled in each particularcase. Concepts derived from the discourse analysis school, such as hegemony, nodal points or sedimentation, are useful to understand the strategies to construct the symbolic reality in each case. This reality will depend on the political imaginary which determines ‘what is possible to do’ and ‘what is tolerable’ in each particular society. The election of limited realities, focused only on formal nstitutions, has been constant in the analyzed discourses, which explains why the reforms were inefficient to remove common cultural practices such as clientelism.
