    The Macuira Gneiss is a Paleozoic metamorphic unit that outcrops in the Simarua, Jarara and Macuira ranges, Alta Guajira. It is composed by a lithologies metamorphosed under amphibolite facies P-T conditions and consist of amphibolitic and quartz feldspathic gneisses, amphibolites, schists, pegmatites, calc-silicated rocks and marbles, with migmatization evidences in gneisses and amphibolites. Five foliations (S1-5) and three folding events (F1-3) were identified and interpreted as product of two metamorphic events, developed in a progressive barrovian metamorphic gradient of intermediate pressure with intermediate P-T ratio, interpreted as product of continental collision tectonics. This unit is important in understanding of the tectonic evolution of the Alta Guajira and Caribbean because it records different deformational phases pre-, syn- and post-migmatitic, that could be related with different tectonic episodes: the first associated with the collision between Laurasia and Gondwana (Alleghanian Orogeny - Late Paleozoic), and the second related with the Caribbean Plate evolution (Andean Orogeny - Meso-Cenozoic).

    In the northernmost portion of the Serrania de Jarara (Alta Guajira, Colombia, low - medium grade metamorphic rocks from the Etpana Metamorphic Suite were thermally affected by emplacement of a small calc-alkaline intrusion (Parashi Stock. Detailed petrographic analysis in collected rock samples across the NE and NW plutonic contacts show occurrences of textural and mineralogical changes in the country rock fabric that evidence contact metamorphism overprinting regional metamorphism of the Etpana Suite. These changes include growth of andalusite (chiastolite, calcic clinopyroxeneand amphibole porphyroblast crosscutting Sn+1 metamorphicfoliation. Hornblende-plagioclase barometry (ca. 3.1 kbar and cooling models for the stock show maximum time temperature evolution in the country rock at the interpreted depth of intrusion (ca. 11 km and help to evaluate the behavior of the country rock with the changing local geotherm.

    In the last 18 years, epizootics of Venezuelan equine encephalitis have not occurred in places with historic epidemic register (1925-1995) in the Guajira Peninsula, Colombia. To assess if the Guajira Peninsula, Colombia, still maintains the epidemiological conditions for Venezuelan equine encephalitis virus reemergence. Research was carried out in places affected by the 1995 epidemic. We evaluated: 1) abundance and seasonal variation of vector mosquito populations; 2) availability of mammals that are potential amplifiers of the virus, and 3) knowledge among the community about the disease and its vectors. Most of the 16 mosquito species were found during the rainy season. Aedes taeniorhynchus and Psorophora confinnis showed direct relation with rainfall and temperature. In contrast, the dominant species, Deinocerites atlanticus , was always present in the collections, regardless of climatic conditions. No IgG antibodies were found in humans younger than 17 years old, goats or bovine sera. One third of those interviewed remembered the last epidemic and had basic understanding of the disease. Only 20% of the families were owners of equines, and 8% was informed of the importance of equine vaccination. Some epidemiological conditions that eventually could help epizootic Venezuelan equine encephalitis virus reemergence are maintained. However, an abrupt decrease in the number of susceptible equines was found in the area. Apparently, this new condition has not allowed the virus reemergence and is the biggest observed change.

    The background notes by the U.S. State Department on Venezuela emphasize the unique economic conditions in this oil-rich nation, and include information on its people, geography, history, government politics, defense and foreign relations. Venezuela, located on the north coast of South America, has 17,791,000 people, growing at a rate of 2.7%. Infant mortality is 2.7/1000, and life expectancy is 70 years. Geography ranges from the scarcely populated highlands between the Orinoco river and Guyana, the Orinoco plains, to the populated Andes mountains and coast. 80% of the population is urban. Literacy is a priority at 88.4%; Technical and university education is increasing; emigration from other countries is common because of relatively good working conditions. Venezuela has a long history of self government, having become independent in 1921. Now the democratic constitutional government is effective in improving both internal and regional development and human rights. The economy is based on oil production and refining, as well as steel and aluminum, all nationalized industries. Self-sufficiency in agriculture is a national goal. Because of the rapid population growth rate, however, per capita income and GNP are stagnating.

    In 1995, the first Venezuelan equine encephalitis (VEE) outbreak in Colombia in 22 years caused an estimated 75,000 human cases, 3000 with neurologic complications and 300 fatal, in La Guajira State. Of the state's estimated 50,000 equines, 8% may have died. An epizootic IC virus, probably introduced from Venezuela, was rapidly amplified among unvaccinated equines. Record high rainfall, producing high densities of vector Aedes taeniorhynchus, led to extensive epidemic transmission (30% attack rate) in the four affected municipalities. Native Wayuu Indians, constituting 24% of the state's population, were at increased risk of infection (risk ratio, 3.3; 95% confidence interval, 2.2-5.3). Epidemiologic studies found no evidence of human-to-human transmission. A higher-than-expected number of abortions during the outbreak confirmed a previously suspected abortifacient role of VEE infection. Pesticide applications and a mass equine vaccination program contributed to preventing the outbreak's spread south of La Guajira.

    This discussion of Venezuela reviews the following: the history of the country's demographic situation; the government's overall approach to population problems; statistical systems and development planning; institutional arrangements for the integration of population within development planning; the government's view of the importance of population policy in realizing development objectives; population size, growth, and natural increase; morbidity and mortality; fertility; international migration; and spatial distribution. Over the 1920-1961 period Venezuela's level of fertility was high and continued to rise gradually. The crude birth rate was around 40.0/1000 population in 1920, 44.0/1000 in 1950, and 45.0/1000 in 1961, and thereafter began to decline, dropping to a level of 38.4/1000 by 1971. During the same period, mortality underwent a steady decline, with the crude death rate falling from 30.0/1000 population in 1920 to 13.7 in 1950, 7.4 in 1961, and to 6.6 by 1971. Venezuela's government has no policy of intervention to modify fertility or population growth but has relied primarily on the benefits of rapid economic growth to achieve a rate of demographic growth that is compatible with its development objectives. Since 1920, 7 modern censuses have been conducted. The most recent census was in 1971. The registration data are classified as incomplete. Multiround sample household surveys were conducted in 1976-1977 and 1978. The government has not established a special unit for population policies. It assigned this function to the Central Planning Agency in 1975. The government has not announced a comprehensive population policy, but it has been moving in the direction of formulating more comprehensive policies in 2 areas of concern--international migration and spatial distribution. The government considers the current rate of population growth to be satisfactory despite the fact that it is rather high by Latin American standards. The government also considers

    Full Text Available La mayoría de los ríos en las montañas andinas de Venezuela en la cuenca del Orinoco sufren variadas perturbaciones. A pesar de esto, sus comunidades de peces han sido poco evaluadas en términos de sus gradientes espaciales y temporales. La generación de información sobre estas comunidades es prioritaria, y puede impulsar la conservación de los recursos hidrobiológicos regionales. Con este fin, seis localidades fueron evaluadas mensualmente en tributarios de la cuenca alta del río Turbio en la Sierra de Portuguesa (770-1 305msnm durante el período de sequía y el inicio del período de lluvias (enero-abril de 2012, se caracterizaron las dimensiones del cauce, el sustrato y las variables físico-químicas del agua. Se utilizó electropesca para determinar el número y abundancia de especies de peces. Las comunidades de peces y su estabilidad se evaluaron explorando los cambios en la riqueza y abundancia y por coeficientes de variación, clasificación jerárquica y análisis de escalamiento multidimensional no métrico. El estado de conservación de las localidades se estimó con un índice de integridad del hábitat. La riqueza de 12 especies varió según la elevación, los tributarios y el estado de conservación de las localidades. Chaetostoma dorsale, Creagrutus taphorni y Chaetostoma milesi comprendieron el 90.8% de la abundancia relativa y mantuvieron los primeros rangos durante el período. Las comunidades tuvieron poca variación espacio-temporal y esta se expresó en un gradiente asociado principalmente por las coberturas de sombra, rocas y grava, la temperatura del agua y la conductividad. La estabilidad fue moderada, variando con la elevación y el estado de conservación de las localidades. Los tributarios en la cuenca alta del río Turbio se encuentran bajo impactos severos y sus ictiofaunas son empobrecidas y en situación de riesgo.

Se detectó por métodos serológicos la presencia de anticuerpos totales del VHB (anti-HBc total, y en las positivas se investigó la presencia del antígeno de superficie (HBsAg y del antígeno "e" del VHB (HBeAg. La prevalencia de anti-HBc total fue de 72,9% en el sexo femenino y 81,1% en el masculino, la prevalencia de HBsAg fue elevada (61,1% en el sexo masculino, sólo cuatro de los portadores de HBsAg fueron positivos para HBeAg. Los resultados obtenidos indican un grado elevado de endemia para esta infección y que su diseminación comienza a temprana edad. El factor involucrado en la adquisición y diseminación del virus seria la vía sexual. Hacinamiento, contacto intercorpóreo con fluidos biológicos, prácticas sociales, y características de la cepa viral circulante podrían estar involucradas en la alta cronicidad observada en la comunidad indígena Japreira.The aim of this study was to determine the prevalence of hepatitis B virus (HBV infection in the Japreira indigenous community, Venezuela, and its relationship to age and gender. An intentional, non-probabilistic sample of 149 individuals was selected from a total of 300. All samples were studied for the presence of total HBV antibodies (total anti-HBc, and the positive samples were tested for HBV surface and "e" antigens (HBsAg, HBeAg. Overall prevalence rates of total anti-HBc were 72.9% in females and 81.1% in males. The highest prevalence of HBsAg was observed in males 26-35 years of age. Only four of the 44 HBsAg carriers were positive for HBeAg. The results showed a high endemic HBV infection rate and indicated that its spread begins at early ages. Sexual transmission may be the main route for spread of the virus

Con el propósito de integrar la información disponible sobre el sistema se construyó un modelo trófico de 27 grupos funcionales usando el programa Ecopath 5.0 Beta. Se obtuvo una base cuantitativa para compararlo con otros sistemas de surgencia. La Guajira presenta una biomasa total de 68 t/km²/año, la producción primaria neta del sistema es de 1 248.51 t/km²/año y las transferencias totales del sistema son de 3 275 t/km²/año, lo que indica un ecosistema con una surgencia moderada comparada con otros sitios. Las mayores transferencias de energía se dan del nivel trófico I-II (68.93 %, aunque existe una importante proporción de flujos al detritus (32 %. Los resultados en los atributos de madurez del sistema sugieren que La Guajira es un ecosistema inmaduro debido a que la relación P/R excede a 1 y está en desarrollo debido a la baja ascendencia (33.7 % y alta capacidad de desarrollo (66.3 % como ocurre con otras surgencias donde se presentan valores de ascendencia entre 20 % y 35 %.

    Full Text Available Este trabajo parte de la hipótesis que sostiene que la ausencia o débil presencia del Estado colombiano en sus periferias, en este caso en el departamento de La Guajira fronterizo con Venezuela, ha posibilitado que a través de la historia agentes no estatales construyan poderes paralelos basados en la fuerza y el uso de la violencia. De esta manera establecen órdenes sociales y económicos básicos que permiten la convivencia. En gran parte de La Guajira, especialmente en la frontera con Venezuela, la violencia se ha convertido en el medio utilizado para la resolución de las tensiones y los conflictos sociales, es decir, la violencia y quienes la administran o ejercen han pasado a ser el elemento dinamizador del desarrollo de la vida en común.

Dada la situación que presenta hoy en día Venezuela, aunado a la alta inflación y la devaluación de la moneda; el escenario resulta bastante complicado para el consumidor y las empresas proveedoras de bienes y servicios. En este sentido, las PyMES turísticas de Mochima, ubicadas en el Estado Sucre, Venezuela, se presentan como una alternativa para de alguna manera ayudar a disipar ese triste escenario, mediante sus bondades y en combinación con Internet. De allí que el presente artículo aborde desde los aspectos teóricos del turismo hasta las bondades naturales y culturales que ofrece esta zona oriental del país. Se utilizó una metodología de carácter descriptiva y una combinación de estrategia documental y de campo. Se aplicó un muestreo no probabilístico de tipo intencional, seleccionando los elementos con base en criterios de los investigadores. De acuerdo al estudio, se diseñó la página web y se concluyó, que la implementación de la misma ayudaría en gran medida a mejorar los ingresos de la región y darse a conocer tanto a nivel nacional como internacional.

Su objetivo fue analizar los elementos que caracterizan el capital social en la población objeto de estudio. Para la obtención de la información se utilizaron los enfoques cuantitativo y cualitativo. El tipo de investigación fue descriptiva-explicativa y las técnicas primarias aplicadas fueron la encuesta, el grupo focal y la entrevista. Los resultados evidencian que la población de los resguardos tiene sus necesidades básicas insatisfechas. En la cohesión social, se observa que los lazos de consanguinidad son los de mayor relevancia. En cuanto a la participación cívica y política, esta tiende a ser más evidente en dinamismos políticos que en otro tipo de actividades. Confían tanto en sí mismos como en sus familiares y la solidaridad que se practica es alta. Se concluyó que la comunidad wayuu posee un gran potencial de capital social acumulado, demostrado en su diario accionar.

    The Cocinetas Basin in the Guajira Peninsula, the northernmost tip of South America, today has a dry climate with low rainfall (ten months) and no year-long rivers or permanent standing bodies of fresh water. In contrast, the fossil and geological record indicate that the Cocinetas Basin was much wetter during the Miocene-Pliocene (∼17-2.8 Ma). Water needed to sustain the paleofauna could either have originated from local sources or been brought by a larger river system (e.g. proto Magdalena/Orinoco river) with headwaters either in Andean ranges or the Guyana shield. We present a provenance study of the Pliocene Ware Formation, using petrographic analysis of conglomerate clasts and heavy minerals, and U-Pb dating of 140 detrital zircons. Clasts and heavy minerals are typical of ensialic metamorphic and igneous sources. The detrital zircon age distribution indicates the Guajira ranges as the most probable sediment source. The overall results indicate that the fluvial system of the Ware Formation drained the surrounding ranges. The water was probably derived by local precipitation onto the Guajira peninsula.

    1986-11-01

    Immigration to Venezuela is examined using census data with the focus on the period 1971-1981. A brief overview of trends since the beginning of the twentieth century is first presented. The analysis indicates that "immigration to Venezuela is clearly of a short-term nature. Flows follow job opportunities and adjust to the labour market and to the financial capacity of the exchange market. The large increase of migratory movements to Venezuela in the 1970's is characterized by a diversification of their places of origin and by a greater instability. To a large extent, the migrants are illegal, especially those coming from Colombia and the Caribbean islands. Because of the crisis of the early 1980's, which is now worsened by the down trend of both oil prices and the U.S. dollar, Venezuela has become less attractive to immigrants, particularly from neighbouring countries." The authors observe that migrants in Venezuela are not well integrated and may depart, disrupting the labor supply in certain technical and specialized occupations (SUMMARY IN ENG AND SPA) excerpt

    Full Text Available Introduction. Knowledge of vector insect species, their habitat and geographical distribution is crucial for determining the risk of transmission of the etiologic agents that cause disease in humans, which allows defining strategies for prevention, surveillance and control in line with the characteristics of each area. Objective. To determine the presence and public health importance of vectors of Chagas disease in the indigenous settlements of Marbacella and El Horno of the Wayúu ethnic group in the municipality of Riohacha, La Guajira, Colombia. Materials and methods. From active search, installation and inspection of biosensors and occasional catches, Hemiptera: Reduviidae: Triatomini were collected intra and in the peridomicile housing of the indigenous settlements of El Horno and Marbacella of the the Wayúu ethnic group. Indices of intra and peridomestic infestation, colonization, density, dispersion and natural infection with Trypanosoma cruzi Chagas, 1909 were calculated.

    Venezuela had an aggressive nuclear program when it was under a dictatorship in the 1950s, but it is currently assuming a wait-and-see stance. The country has one small research reactor, but it may have a reactor on-line in the mid-1990s. CONADIN, Venezuela's nuclear energy planning agency, has commissioned feasibility studies and requested proposals for a reactor-siting survey. A recent study for the Venezuelan state oil company suggests tha a natural-uranium, gas-cooled reactor could provide process steam to extract oil from the bituminous tar sands of the Orinoco Basin. Venezuela is also exploring for uranium reserves. 23 references, 1 figure, 2 tables

Solamente en las lagunas de estabilización registramos un éxito de eclosión positivo (56,9 %.

La baja anidación registrada en la zona rehabilitada pudo haberse debido a una extracción de hembras adultas, a factores limitantes del hábitat que influyen en el crecimiento de los individuos, o por factores de tipo demográfico. Las diferentes variables estudiadas a nivel de los huevos y los neonatos en los tres sectores, evidencian la posibilidad de que las hembras anidantes posean tamaños mayores que las de otras poblaciones de Colombia sometidas a la cacería. Sin embargo, para establecer el grado de variación geográfica, es necesario determinar la variación temporal de las características reproductivas en la población del Cerrejón.

    There is great concern about the effect of climate change in arid and subarid areas of the tropics. Climate change combined with other anthropogenic activities such as deforestation, fires and over-grazing can accelerate their degradation and, consequently, the increases in losses of biological and economic productivity. Climate models, both local and global, predict that rainfall in the arid Peninsula of La Guajira in the Colombian Caribbean would be reduced and temperature would be increased as a result of climate change. However, as there are only suitable climate records since 1972, it is not possible to verify if, indeed, this is happening. To try to verify the hypothesis of reducing rainfall and rising temperatures we developed a growth ring chronology of Capparis odoratissima in the Middle Peninsula of La Guajira with 17 trees and 45 series which attain 48 years back. We use standard dendrochronological methods that showed statistically significant linear relationship with local climatic variables such as air temperature, sea surface temperature (SST), annual precipitation and wind speed; we also reach to successful relationship of the chronology with global climatic variables as the indices SOI and MEI of the ENSO phenomenon. The transfer functions estimated with the time series (1955 and 2003) do not showed statistically significant trends, indicating that during this period of time the annual precipitation or temperatures have not changed. The annual nature of C. odoratissima growth rings, the possibility of cross-dated among the samples of this species, and the high correlation with local and global climatic variables indicate a high potential of this species for dendrochronological studies in this part of the American continent.

    Venezuela's struggle to develop its economic and political independence separate from the colonialism of foreign oil companies and free from the authoritarian dictatorships of other developing countries is described by one who has been intimately involved in the nation's political life and is knowledgeable in the relationships of oil, economics, and politics during the bid for democracy and economic egalitarianism. First published in 1956, the treatise has been revised and updated to show how strong party organization was responsible for developing demoncratic programs and how this new strength allowed Venezuela to domesticate much of the foreign involvement in oil production. Historical facts, though acknowledged to have a bias, are documented. 88 references. (DCK)

    2007-07-01

    Venezuela is an important player in the energy world, because of its hydrocarbons reserves. The process for calculating oil and associated gas reserves is described bearing in mind that 90% of the gas reserves of Venezuela are associated to oil. Likewise, an analysis is made of the oil reserves figures from 1975 to 2003. Reference is also made to inconsistencies found by international experts and the explanations offered in this respect by the Ministry of Energy and Petroleum (MENPET) and Petroleos de Venezuela (PDVSA) regarding the changes that took place in the 1980s. In turn, Hubbert's Law is explained to determine peak production of conventional oil that a reservoir or field will reach, as well as its relationship with remaining reserves. Emphasis is placed on the interest of the United Nations on this topic. The reserves of associated gas are presented along with their relationship with the different crude oils that are produced and with injected gas, as well as with respect to the possible changes that would take place in the latter if oil reserves are revised. Some recommendations are submitted so that the MENPET starts preparing the pertinent policies ruling reserves. (auth)

    1998-01-01

    The genetic structure of Zulia State, Venezuela, was studied through the distribution of surnames from individuals above 40 years of age, obtained from the register of electors. The sample studied consisted in 440, 190 individuals and 10,423 different surnames. For each of the 81 counties of the State, the following estimators were calculated: percentage of the population included in surnames which appear only once (estimator A), percentage of the population included in the seven most frequent surnames (estimator B), the coefficient of consanguinity due to random isonymy phi ii, and Karlin and McGregort's ni (v), an estimator of migration. The correlation between phi ii and B was 0.92, indicating that 85% of the variation observed in the coefficient of consanguinity due to random isonymy is due to the seven most frequent surnames. The correlation between A and ni was 0.93, so that 86% of the variation observed in ni, is due to surnames which appear only once. On the other hand, correlations between A and B, and between phi ii and v were non significant (-0.08 and -0.17 respectively), meaning that they are measuring different features of population structure: B and phi ii, isolation, while A and v, migration. The most isolated counties of Zulia are localized towards the northwestern portion of the State, within the Venezuelan Guajira, although relative isolation is also observed in the southern counties. Isolation by distance is estimated through the correlation between the logarithmic transformations of Euclidean and geographic distances, giving a value of 0.63. This high value might be partially due to the barrier effect of the Lake of Maracaibo. Eight surnames with a focal distribution within Zulia were identified: Almarza, Badell, Bastidas, Bohórquez, Cardozo, Carmona, Espina and Matos. Carriers of these surnames have a high probability of having their origin at the counties where they are localized.

    The incidence of type 2 diabetes (T2D) and its economic burden have increased in Venezuela, posing difficult challenges in a country already in great turmoil. The aim of this study was to review the prevalence, causes, prevention, management, health policies, and challenges for successful management of diabetes and its complications in Venezuela. A comprehensive literature review spanning 1960 to 2015 was performed. Literature not indexed also was reviewed. The weighted prevalence of diabetes and prediabetes was estimated from published regional and subnational population-based studies. Diabetes care strategies were analyzed. In Venezuela, the weighted prevalence of diabetes was 7.7% and prediabetes was 11.2%. Diabetes was the fifth leading cause of death (7.1%) in 2012 with the mortality rate increasing 7% per year from 1990 to 2012. In 2012, cardiovascular disease and diabetes together were the leading cause of disability-adjusted life years.T2D drivers are genetic, epigenetic, and lifestyle, including unhealthy dietary patterns and physical inactivity. Obesity, insulin resistance, and metabolic syndrome are present at lower cutoffs for body mass index, homeostatic model assessment, and visceral or ectopic fat, respectively. Institutional programs for early detection and/or prevention of T2D have not been established. Most patients with diabetes (∼87%) are cared for in public facilities in a fragmented health system. Local clinical practice guidelines are available, but implementation is suboptimal and supporting information is limited. Strategies to improve diabetes care in Venezuela include enhancing resources, reducing costs, improving education, implementing screening (using Latin America Finnish Diabetes Risk Score), promoting diabetes care units, avoiding insulin levels as diagnostic tool, correct use of oral glucose tolerance testing and metformin as first-line T2D treatment, and reducing health system fragmentation.

    The Colombian slider turtle (Trachemys callirostris callirostris) is a subspecies under a high level of exploitation in Colombia, of which nothing is known about its reproduction in highly disturbed areas with low hunting pressure. We studied some reproductive traits in three different aquatic environments created by coal mining in the Cerrejon Mine, La Guajira Department, during part of the reproductive season in 2011 (between March and June). We recorded hatching success (56.9 %) only in the stabilization ponds. In the mining reservoir, the 100 % predation rate was the factor limiting hatching success. The recommended option there is protect the nests from the main predator (Procyon cancrivorus) and the relocation of some of them for ex-situ incubation. The low level of nesting recorded in the rehabilitated area may have been the result of extraction of adult females, but also could be due to habitat limiting factors influencing the growth of individuals, or by demographic factors. Size variables measured for clutches, eggs, and hatchlings at the three study sites, showed the possibility that nesting females are larger than those of other populations subjected to hunting in Colombia. However, to determine the extent of geographic variation when compared to other populations it will be necessary to examine temporal variation in reproductive traits of the Cerrejon Population.

  6. Potential for Great Thrust Earthquakes in NE Colombia & NW Venezuela

    Sixty-five percent of the ≈19 mm/yr eastward velocity of the Caribbean Plate north of Aruba and the Guajira peninsula relative to the South American plate is accommodated by dextral slip on the Bocono Fault system in NW Venezuela at 12±1 mm/yr, the remaining ~3 mm/yr of shear apparently distributed to the NW of the fault (Perez et al., 2011). The N40E strike of the Bocono fault system, however, requires that 10.6±1 mm/yr of convergence should accompany this partitioned dextral shear, but GPS measurements reveal that less than 25% of this convergence occurs across the Venezuelan Andes. The remaining 6-8 mm of convergence is presumably accommodated by incipient subduction between the Bocono fault and a trench 300 km NW of the northern coast of Colombia. Hence NW Venezuela and NE Colombia may occasionally host great earthquakes. Our current poor understanding of the geometry of the plate interface permits the plate to be locked 300 km down-dip and possibly 600 km along-strike, and if the plate slips in 10 m ruptures it could do so every 1200 years in a M~9 earthquake. No great earthquake has occurred since 1492, since when ~4 m of potential slip has developed, but should slip occur on just 10% of the hypothesized décollement (100x150 km) it could do so now in an Mw=8.2 earthquake. In that a potential Mw>8 earthquake poses a future seismic and tsunami threat to the Caribbean it is important to examine whether great earthquakes have occurred previously near the NW Venezuela coast. It is possible that creep accommodates the entire convergence signal, since there is no suggestion from microseismicity for an abrupt locked-to-sliding transition, as, for example, signifies its location in the Himalaya. An alternative measure of future potential seismic energy release is to identify the locus and rate of present-day strain contraction. To this end, Venezuelan, Colombian and US (CU and UNAVCO) investigators are installing an array of more than a dozen continuous operating

    2004-01-01

    In this work, the burning velocity of premixed laminar flames of methane-air and Guajira natural gas-air mixtures was measured by the cone's angle method using a cylindrical Bunsen burner. In the development of the experiments, a fuel concentration in the fuel-air mixture ranging from 9% -11% was taken. The maximum value of the burning velocity was obtained for mixtures a little bit richer than the stoichiometric case. For methane, this flame velocity was 44.1 cm/s and for the Guajira natural gas was 43.1 cm/s. From the results, it was possible to see that the Guajira natural gas inert content led to a burning velocity value lesser than the methane's, in spite of the Guajira natural gas having a higher heavy hydrocarbon content. Methane burning velocity values following similar trends to those reported by the literature were obtained. The systematic error found in the results is mainly a consequence of inaccuracies in the method used to measure the fuel-gas mixture velocity at the burner exit

Sin embargo, para que las prácticas de desarrollo alcancen las metas de conservación del medio, usando los conocimientos científicos y las tecnologías que han surgido a partir de estos, es necesario interpretar y conciliar los diferentes enfoques de la sustentabilidad con base en procesos que democraticen la educación en los niveles superiores. Esto último facilita la transferencia de los saberes científico-tecnológicos en las comunidades de acuerdo con los principios del ecoturismo. Las anteriores son algunas conclusiones surgidas de la realización del presente trabajo de tipo reflexivo, que se llevó a cabo, según los parámetros de una metodología descriptiva y técnica de revisión bibliográfica, en el entorno de Riohacha, capital del departamento de La Guajira (Colombia, y cuyo propósito es contribuir a la sustentabilidad regional desde una perspectiva académica.

  19. EL MESTIZAJE EN UNA FRONTERA DEL CARIBE: EL CASO DEL PUEBLO DE BORONATA EN LA GUAJIRA, 1696-1776

    Full Text Available La historia del mestizaje refleja más que el aspecto biológico aso- ciado a la mezcla de razas que genera un prototipo humano, y se sitúa también en las variadas dinámicas históricas que posibilitan a las sociedades relacionarse en diferentes niveles y construir, desde esas relaciones, complejos procesos identitarios. En ese sentido, este artículo analiza el proceso de mestizaje en el pueblo de Boronata, ubicado en el sur de la península de la Guajira durante el período 1696-1776, donde los elementos culturales nativos jugaron un papel central en las relaciones que se dieron entre las sociedades criolla y aborigen. Para ello se analizan e interpretan una variedad de fuentes de la época consistentes en censos de poblaciones e informes de mi- litares y misioneros que se desempeñaron en la Guajira.

Venezuela has oil reserves of 73 billion barrels, gas reserves of 143 TCF and coal reserves of 6 billion BOE. The country has a refining capacity of 2.9 million barrels per day, a petrochemical capacity of 7.7 million tons per year, and a coal capacity of 4.6 million tons per year. The largest refiners in Venezuela are Shell, Exxon, PDVSA, Mobil, BP, Chevron and Texaco. In 1996 the total oil and derivatives exports for Venezuela were 2.8 million barrels per day. Fifty-eight companies from 14 countries participate in the Venezuelan upstream market. Fifteen operating agreements have been awarded to 27 companies from nine countries. Third round operating agreements have been awarded to 26 companies and profit sharing agreements are in force involving 14 companies. Four vertically integrated projects (Maraven-Conoco, Maraven-Total, Corpoven-Arco-Texaco-Phillips, and Lagoven-Mobil-Veba) are currently underway. The Orimulsion(R) project, the refining system, the natural gas production, marketing and transmission system, associated future projects for the 1997-2006 time frame, and developments in the field of petrochemicals also have been reviewed. 21 figs

    Full Text Available In the above article author describes evolution of legal regulation of international commercial arbitration in Venezuela. Author cites statistics of arbitration centers in Venezuela activities. In past two decades many Latin American countries have reformed their arbitration law. In an effort to modernize its arbitral institutions several Latin American countries adopted Model Law on International Commercial Arbitration of the UN Commission on International Trade Law (UNCITRAL. In addition, many Latin American countries have adopted the monistic system. Author pays detailed attention to this issue, discusses concept of a monistic system - a system in which a unique set of rules governs both domestic and international arbitration. Author argues that legal system of Venezuela fits this definition. Venezuelan law on arbitration in 1998 makes no distinction between domestic and international arbitration. Arbitration was included in judicial system under the Constitution of Venezuela of the 1999. Art. 258 of the Venezuelan Constitution states that arbitration, conciliation and mediation are alternative ways of resolving disputes.

    Sporotrichosis is one of the most common subcutaneous mycoses in Venezuela. It is a granulomatous chronic infection with cutaneous or subcutaneous tissue lesions. Regional lymphatic involvement may be present; extracutaneous disease is rare. The causal fungus Sporothrix schenckii has been isolated from soil, vegetation, and animals on numerous occasions and in many localities throughout the world. The aim of this study is to describe clinical and epidemiological features of cases of sporotrichosis observed in Venezuela and review of the literature. We included the demographic data, clinical features, diagnostic methods, treatment, and follow-up of patients with sporotrichosis from 1963 to 2009, diagnosed at the Department of Medical Mycology. One-hundred and thirty-three sporotrichosis cases were diagnosed. Most patients were under the age of 30 years (66.15%). In 61.6% of them, the mode of transmission was not identified. The predominant clinical form in this population was lymphocutaneous (63.15%). Direct microscopic diagnosis was performed in 123 cases, and 57.9% yielded positive results for asteroid body. Sporotrichosis is an endemic subcutaneous mycosis in Venezuela. There are no reports to this date of disseminated forms of the disease, even amongst patients with acquired immunodeficiency syndrome. Direct microscopic examination of wet mount slides with saline solution or distilled water in the search for asteroid bodies is paramount. Saturated sodium and potassium iodine solutions continue to be extremely efficacious and affordable to most of our patients, therefore our treatment of choice. © 2013 The International Society of Dermatology.

  11. Venezuela opens up to explorers

    International Nuclear Information System (INIS)

    Kielmas, M.

    1995-01-01

    The opening of Venezuela's first exploration bidding round since oil nationalisation in 1976 was a turning-point in the country's energy policy. The state oil company, Petroleos de Venezuela (PdVSA), has said that the bidding round could generate investment of some $11 billion eventually in development investment and that over the next 10 years, nearly 20 percent of a planned $55 billion, 10-year state oil company investment programme could also come from foreign or private sector oil investment. Should this optimistic prediction materialise, Venezuela, whose 2.75 million b/d oil production in October was some 400,000 b/d over its Opec quota, will remain both the dominant oil producer in Latin America and the top-ranking oil exporter to the US market. In May this year, Venezuelan oil exports topped 1.43 million b/d, or some 16.8 percent of the US market, compared with Saudi Arabia's 15.7 percent. (author)

    1985-06-01

    Venezuela's current economic and demographic situation is described. Venezuela is a major oil country, and the oil industry accounts for 90% of the country's foreign exchange, 70% of the government's revenues, and 15% of the gross domestic product. The economy experienced a sudden and high rate of economic growth in the mid-1970s as a result of high oil prices; however, in recent years, declining oil prices have had a negative effect on the economy. The country is now faced with a serious trade deficit, and the government recently imposed restrictions on imports. Imports in recently years had increased markedly. The emphasis on the oil industry weakened the agricultural sector and, as a result, food imports increased. In addition, the rapid economic growth experienced during the 1970s greatly increased the demand for imported consumer goods. Venezuela has the 4th highest foreign debt in the world (US$35 billion). Despite these problems Venezuela has a relatively high per capita income (US$4,140) and living standard, compared to other countries in the region. Venezuela's total population is 14.6 million, and the population is unevenly distributed. 86% of the population lives in cities of 2500 or more. 37.4% of the population and 70% of the industry is concentrated in the Federal District which contains Caracas, and in the surrounding states of Aragua, Miranda, and Carabobo. This area constitutes only 2.36% of the country's territory. Most of the oil fields are located in the state of Zulia which also contains the country's 2nd largest city (Maracaibo). The country's coastal area contains most of the agricultural lands, and the prairies just south of the coastal mountain ranges are devoted primarily to cattle raising. The remaining 58.2% of the country's territory is essentially jungle and contains only 6.9% of the country's population. The annual population growth rate is 3.11%. Although the rate declined in recent years it is higher than in most of the other

    Full Text Available OBJETIVO: Identificar las desigualdades y las características sociodemográficas que inciden negativamente en la mortalidad materna en el departamento de La Guajira, Colombia. MÉTODOS: Se realizó un estudio descriptivo, en el que se analizaron los casos de muerte materna ocurridos en el departamento de La Guajira entre 2010 y 2012, a partir de datos de fuentes secundarias. Se calculó la diferencia de las tasas, la razón de las tasas y el riesgo atribuible poblacional porcentual, además de los índices de Gini y de concentración. RESULTADOS: Se registraron 54 muertes maternas, de ellas, 61,1% eran indígenas y 16,7% afrocolombianas; la mayoría no tenía ningún estudio (33,3% o solo estudios primarios (29,6%. Se encontraron desigualdades en la diferencia de las tasas, la razón de las tasas y el riesgo atribuible poblacional porcentual, entre La Guajira y otros departamentos de la región Caribe y del país; sin embargo, esas diferencias no se reflejaron en los índices de Gini y de concentración. CONCLUSIONES: La mortalidad materna fue significativamente más elevada en las mujeres indígenas en comparación con las no indígenas. Se deben fortalecer los programas de salud sexual y reproductiva y adelantar dentro de las políticas de salud materna un enfoque multicultural para eliminar o reducir las desigualdades relacionadas con la mortalidad materna en esta población.

    Full Text Available En la presente revisión se presenta información sobre superficie, producción, y rendimiento de los frutales en Venezuela. Además se hacen consideraciones sobre los sistemas de producción, destacando limitaciones, avances y sugerencias. La fruticultura en Venezuela ocupa el 3er. lugar dentro del sector agrícola vegetal. Existen 167.691 Ha de frutales y una producción 2.232.088 TM por año. Se producen comercialmente una docena de rubros frutícolas, siendo los principales: plátano, banano, naranjo y piña. Las áreas de producción van desde zonas bajas y áridas, en donde se obtienen uvas y piñas; hasta zonas altas y húmedas donde se hallan duraznos y fresas. Ha habido reducción de la superficie plantada, con excepción de lechosa, piña y aguacate. El manejo hortícola de los huertos frutícolas es heterogéneo, ya que se observa desde bajo hasta alto nivel de tecnología. La incorrecta aplicación de las prácticas hortícolas origina baja productividad y calidad de fruta. La poscosecha podría mejorarse a través del desarrollo e implementación de normas de clasificación, empaque, embalaje, y cadena de frío. La exportación de frutas venezolanas se ha reducido en los últimos años y se concentra en mango, naranja y lima Tahití. Los principales destinos son Colombia, Europa, Norteamérica y las islas del Caribe. Sólo la naranja se procesa de manera importante en Venezuela. Las perspectivas para la fruticultura venezolana es continuar como una actividad dirigida al mercado interno, no se vislumbra una mayor participación del país en el mercado internacional.

Digital image processing methods used to enhance LANDSAT ETM imageries and to produce morphometric maps (such as hillshade, slope, minimum and maximum curvature maps based on the SRTM DEM data contribute to the detection of morphologic traces that might be related to catastrophic tsunami events. These maps combined with various geodata such as seismotectonic data in a GIS environment allow the delineation of coastal regions with potential tsunami risk. The LANDSAT ETM imageries merged with digitally processed and enhanced SRTM data clearly indicate areas that might be prone by flooding in case of catastrophic tsunami events.

    Full Text Available El propósito de este artículo es analizar las estrategias de innovación desarrolladas por los centros de investigación de las universidades públicas del Departamento de La Guajira, Colombia. La investigación es de tipo descriptivo, de diseño no experimental, transversal de campo. La población está conformada por la Universidad de La Guajira y la Universidad Nacional Abierta y a Distancia. La técnica de recolección de datos fue la encuesta con escala tipo Likert. Para el análisis de la información se determinó la media, interpretada a través de baremos con rango establecidos. Los resultados permitieron conocer que las universidades objeto de estudio no tienen estrategias de innovación diseñadas, ya que realizan pocas actividades de investigación y desarrollo, son pocos los incentivos otorgados a los investigadores, la cultura organizacional existente no fomenta la creatividad e innovación y se presenta un bajo uso de tecnologías de información y comunicación. Por lo anterior, es necesario establecer estrategias de innovación como herramientas esenciales para generar ventajas competitivas y alcanzar el éxito de estas universidades.

    Zimmerman, R H

    2000-01-01

    The author reviews the malaria research program in Sucre State, Venezuela, taking an ecosystem approach. The goal was to determine which methods could have been introduced at the onset that would have made the study more ecological and interdisciplinary. Neither an ecosystem approach nor integrated disease control were in place at the time of the study. This study began to introduce an ecosystem approach when two contrasting ecosystems in Sucre State were selected for study and vector control methods were implemented based on research results. The need to have a health policy in place with an eco-health approach is crucial to the success of research and control. The review suggests that sustainability is low when not all the stakeholders are involved in the design and implementation of the research and control strategy development. The lack of community involvement makes sustainability doubtful. The author concludes that there were two interdependent challenges for malaria control: development of an ecosystem approach for malaria research and control, and the implementation of an integrated disease control strategy, with malaria as one of the important health issues.

    The Wabamun power plant has been shut down after 54 years of service in Alberta. The phased shut-down of the 4-unit plant was announced in 2002, and the last operating unit ended commercial operation on March 11, 2010. As the owners of the facility, TransAlta will now complete the remediation and reclamation work required by the government of Alberta. The 537 MW generating facility has helped to fuel Alberta's economic growth over the last 54 years. TransAlta plans to modernize its coal fleet with the Keephill 3 plant and add more renewable energy sources in the future. The Keephill 3 is a joint venture between TransAlta and Capital Power Corporation. The 450 MW coal-fired power plant is equipped with super-critical technology. The new plant will also be the test site for Project Pioneer, a carbon capture and storage (CCS) initiative.

    Full Text Available As for most batoid species, little is known about the basic biology of the Venezuela round stingray Urotrygon venezuelae (Urotrygonidae. This study presents information about the reproductive biology of the species, including fecundity, embryonic development stage, relationship between maternal size and fecundity, gonadosomatic (GSI and hepatosomatic (HSI indices, sex ratios, maturity size and size at birth. With all this information, a preliminary reproductive cycle is proposed. A total of 269 specimens were caught with beach seine in Salguero beach, Colombian Caribbean Sea, between August 2005 and October 2006. We propose for U. venezuelae a biological cycle with three reproductive peaks: November-December, March-April and August. Size at sexual maturity was calculated in 176 mm (total length for females and 227 mm for males; fecundity ranged between one and six embryos per female. We found that cloacal diameter and liver weight were better predictors for fecundity than total length for U. venezuelae.

The siting of this hall was carefully studied, and such factors as nearness to industrial zones, climate, and ease of access were decisive aspects that were taken into account. The final choice was a site near Morón, in the Carabobo Department, close to the sea. The main constructional item is the roof of the large hall. It is made of a series of hyperbolic-parabolic reinforced concrete thin shells, of rectangular planform, and slightly inclined towards the north, to produce a saw edge profile. Each of these shells is supported by a central column. The hollow spaces along the saw edge profile have been used for ventilation. The enclosing walls consist of trellice material, which also provide ample facility for additional ventilation.Para el montaje de los coches Volkswagen destinados al mercado venezolano, se ha construido una gran nave dotada de todos los servicios necesarios: pintura, engrases, aparcamiento de los vehículos terminados, etc. La elección del lugar más apropiado para la situación de la nave y edificios anexos fue motivo de un detenido estudio, en el que la proximidad a zonas industriales, clima, fácil entrada de materiales procedentes de ultramar y salida para los acabados, fueron los factores decisivos. Definitivamente se eligió un solar en las cercanías de Morón, del departamento de Carabobo, y próximo al mar.

    Venezuela has pioneered a preventive-focused and comprehensive movement for Occupational Safety and Health (OSH) in Latin America. However, despite being an oil-rich country, it has some of the lowest salaries for their workers and highest levels of hyperinflation, devaluation, crime, and violence of the world. Review the current status and challenges on relevant aspects of OSH in Venezuela. Review of literature and documents from national governments, UN agencies, NGOs, and the Venezuelan government concerning OSH and related topics since 1986. Reformed in 2005, the Organic Law on Prevention, Conditions and Environment (LOPCYMAT) was a fundamental moment of change for OSH. Factors which have impacted OSH the strongest are (i) the creation of the National Institute of Occupational Safety and Health (INPSASEL) and (ii) the socioeconomic crisis Venezuela is going through. Venezuela's laws are innovative and yet non-compliance is enormous. Almost half of the population works in the informal sector. Following the International Labor Office projections, 5 people die per day in Venezuela due to occupational accidents or diseases, making health and safety at work a luxury rather than a right. The quality of life for the average worker has deteriorated, affecting not only health but the overall well-being of all Venezuelans. The political and socio-economic situation has led to a mass exodus of more than 1.6 million highly qualified and talented professionals. Many statistics concerning OSH are not updated and are unreliable regarding occupational accidents and diseases. There is a substantial difference between what is written to protect individual Venezuelans in the workplace and the reality of workplace conditions. Substantial governmental actions are needed in the immediate future to improve occupational safety and health of Venezuelan workers. Copyright © 2015 The Author. Published by Elsevier Inc.

    This annual report presents financial information from TransAlta Corp., along with a review of its operations throughout 2003 and a summary of the how the electric utility has performed in terms of power generation, independent power producers, transmission and energy marketing. TransAlta is one of the largest non-regulated power generation and wholesale marketing companies in Canada. It's assets include coal-fired, gas-fired, hydro and renewable generation facilities in Canada, the United States, Mexico and Australia. Reported earnings in 2003 were $1.26 per share compared to $1.17 in 2002. The strong first quarter was followed by harsh market conditions, low water levels which affected hydro production, and pricing restrictions in Ontario that reduced contribution from the Sarnia plant. This report outlines the utility's progress in increasing revenue and producing more power. In 2003, unplanned outages were reduced by 7 per cent and injury frequency rate was reduced by 27 per cent. The installation of 114 wind turbines in Fort Macleod, Alberta, increased TransAlta's renewable energy capacity to 3.7 per cent in 2003. The wind farm produces 75 MW of electricity, enough to power more than 32,500 homes annually. This report summarized the company's energy resource activities and presented an operations review as well as consolidated financial statements and common share information. This included the utility's assets, liabilities, revenues, expenses and cash flows. Revenue and expenditure statements were summarized by source. refs., tabs., figs

Special attention is paid to the projects of Caracas in the energy sector which are aimed at the creating of common energy zone in Latin America. The author has revealed the interaction of internal political processes in Venezuela as the country's leader in the region, with its integration policy, and also identified trends in the further development of energy policy and strategy of Latin American countries. The research of energy resources of Latin America determined that the main factor that works in favor of convergence states within the South American "geopolitical ring" is to ensure energy security. Venezuela is among the richest resources of Latin America. In the research it was determined that Petrosur, Petrocaribe and Petroandina provide the basis for a range of bilateral agreements to promote cooperation, creation ventures based on the state oil companies of these states.

Hubo una tasa de incidencia nacional relativamente estable de 0,2 casos por 100 000 habitantes al año. De los 242 casos, 26,0% eran de Isla Margarita, una de las tres islas que integran el estado de Nueva Esparta (Isla Margarita fue la única de las islas de Nueva Esparta que tuvo casos de LVH. Durante el período de 1995-2000, la incidencia anual en Nueva Esparta osciló de 1,7 a 3,8 casos por 100000 habitantes. Los hombres en Venezuela se vieron afectados con mayor frecuencia (59,5% que las mujeres (40,5%. En cuanto a la edad, 67,7% de los pacientes con LV tenían 4 años de edad y 80,6% tenían menos de 15 años. La tasa de mortalidad entre las personas con LV fue de 7,85% durante el período de 1995-2000. El tamizaje serológico con antígeno rK39 en 1217 perros de Isla Margarita detectó una tasa de positividad de 28,5% (no se les efectuaron pruebas a los perros de las otras dos islas de Nueva Esparta. En cambio, la tasa fue de 2,8% en las 1808 muestras tomadas de perros en los 12 estados en tierra firme. DISCUSIÓN: La LV humana y canina no están uniformemente distribuidas en Venezuela. La distribución podría reflejar factores tales como diferencias entre los estados en términos de densidad poblacional humana, densidad vectorial y la presencia o ausencia de otros tipos de tripanosomas. Se observan tasas especialmente elevadas de infección en niños muy pequeños, así como en perros domésticos, en comunidades semiurbanas de Nueva Esparta, donde no se ha notificado la presencia de otros tripanosomas capaces de infectar al ser humano. Las medidas de control destinadas a limitar la infección canina podrían contribuir al control de la enfermedad en sitios con una alta frecuencia de LV. Para reducir la mortalidad por LV es preciso lograr que los profesionales de la medicina

Esta reorganización se impone con la asignación de unos roles económicos, políticos y culturales específicos a su población, de una “política de la gestión de la diversidad cultural”, de manejo y control de los “otros” de la nación que habitan dicho territorio. Este artículo presenta el proceso histórico, sociológico y político que llevó a una de estas comunidades a transitar de receptora pasiva de las políticas de la empresa Carbones del Cerrejón Limited y del Estado colombiano, a sujeto colectivo étnico.

    Figures of Colombian immigrants in Venezuela in the period 1981-1986 as well as the development of their socio-demographic profile and their integration into the labor market are analyzed by means of ad hoc tables drawn from a Sample Home Survey by the Oficina Central de Estadisticas e Informatica and information from the civil record office. It is estimated that in 1987 there are only half a million Colombians in Venezuela and, contrary to what is generally assumed, not only has the afflux decreased (3/4 of the Colombians entered before 1981), but also a return migration can be observed. Colombian immigration is not homogeneous, but is made up of different groups as far as their professional skills and occupations are concerned. The number of Colombians engaged in household service and those living in rural areas has decreased, but not the number of active farm workers. A greater proportion of Colombians engaged in trade and sales activities is observed, but artisans and skilled labor are still the majority.

    Current health conditions of Venezuela, together with the tropical proliferation of different types of Aedes (aegypti and albopictus), suggest the arrival to this country of ZIKA virus (ZIKV). The Pan American Health Organization urges Latin American countries to take measures to prevent the ZIKV entry and advises that these measures must be designed to detect the introduction of ZIKV in an area, track its spread and actively monitor the disease. In Venezuela and other Latin-American countries, where endemicity is high for other arboviruses such as dengue arid chikungunya, health authorities should strengthen their surveillance systems to detect early and timely introduction of ZIKV ap.d refine diagnostic methods to confirm the infection rate; however, the high incidence of cases due those viral agents reflects weakened and poorly timed insensitive monitoring systems, as well as, poor vector control measures, arising the questions: will this arbovirus pop in our country, will it set as the other as edemicepidemic and lead to alter their clinical behavior and severity of the disease?

Larvae: Anisakidae gen. sp., Brevimulticaecum sp., Contracaecum sp. Type 1, Contracaecum sp. Type 2, Contracaecum sp. Type 3, Eustrongylides sp. All these parasites are reported from Venezuela for the first time and all findings represent new host records. Brevimulticaecum larvae are reported from fishes for the first time. Almost all parasites are briefly described and illustrated and problems concerning their morphology, taxonomy, hosts and geographical distribution are discussed. A new name, Terranova diazungriai nom.nov. is proposed for T. caballeroi Díaz-Ungría, 1968 (a junior homonym of T. caballeroi Barus et Coy Otero, 1966).

    Gulf of Paria exceeded local maximum permissible levels (Cu =20 µg g-1 wet wt; Zn =50 µg g-1 wet wtfor human consumption. These findings indicate that while mussels may be better biological indicators of heavy metal pollution in sediments than oysters,the latter may provide copper and zinc contamination.Further research is needed to determine the most appropriate biological indicators of heavy metal and other pollutants in the local marine environment and to develop protocols for their use.El Golfo de Paria está rodeado por Trinidad y Venezuela y es una fuente significativa de peces y moluscos para el consumo humano.Se extrajo muestras de ostras (Crassostrea rhizophorae y C.virginica ,mejillones (Perna viridis y sedimentos de cuatro sitios de Trinidad y tres de Venezuela en el golfo,así como muestras de tres localidades de la costa norte de Venezuela.El tejido comestible homogenizado de 12 moluscos de cada localidad fue usado para la extracción de metales pesados.El cadmio, cromo,cobre,plomo,níquel y zinc fueron analizados por espectroscopía de absorción atómica a la llama y el mercurio fue determinado por vapor al frío.Las ostras del Golfo de Paria presentaron concentraciones significativamente más altas de cadmio,cobre,níquel y zinc que las de la costa norte de Venezuela;pero esa diferencia no fue aparente en los mejillones.El mercurio en los sedimentos en todos los sitios y también el cadmio,cobre,níquel,plomo y zinc de varios sitios excedieron los niveles permisibles de las normas canadienses y estadounidenses.Los valores de cadmio, mercurio y zinc en los sedimentos se correlacionaron significativamente con los de los mejillones,pero no con los de las ostras.En las ostras los valores de cobre y zinc en varios sitios en el Golfo de Paria excedieron los límites máximos permitidos para el consumo humano.Los mejillones pueden ser mejores indicadores de contaminación de metales pesados en sedimentos,pero las ostras pueden indicar mejor la contaminaci

    Full Text Available La zona de playa de Riohacha, La Guajira, Colombia, constituye un ecosistema muy rico, diverso y productivo, dotado de gran capacidad para proveer bienes y servicios que sostienen actividades como pesca, turismo y navegacion; sin embargo, experimenta problematicas ambientales producto de la dinamica de la ciudad, relacionadas con la infiltración de aguas residuales, acumulacion de residuos solidos organicos y descargue de sedimentos del rio Rancheria. En la metodologia de esta investigación se tomaron muestras de agua de mar en cuatro puntos de un sector de aproximadamente 2.5 km de playa, durante ocho meses en el ano 2013, en epocas de lluvia y sequia. Los metalesanalizados fueron Cobalto, Cobre, Zinc, Aluminio, Manganeso, Niquel y Hierro. Las concentraciones de los metales Ni y Zn, considerados muy toxicos, se encontraron por encima de los niveles segun la normativa nacional y algunas establecidas a nivel internacional, para efectos agudos en aguas marinas y estuarinas destinadas a la preservacion de fauna y flora; las concentraciones de Cu y Zn, se encuentran por debajo de los limites establecidos por la EEA y la EPA. La correlacion significativa existente entre las concentraciones de los metales Fe, Mn, Zn, Co con los nutrientes nitrato y fosfato, indica posible acumulacion de ellos en el sedimento e incluso bioacumulacion en la fauna asociada a esta zona. La presencia y concentraciones de los metales son producto, principalmente, de la intervención humana en las labores de mineria y en el ciclo biogeoquimico de los metales.

    1993-06-01

    A historical review of antimalarials used in Venezuela is presented from the time when the bark of quina was used until the massive distribution of quinine and metoquine by the Dirección de Malariología y Saneamiento Ambiental. The utility of chloroquine and primaquine against sensible parasite isolates and of sulfadoxine-pyrimethamine and quinine, currently used against P. falciparum resistant strains, is thoroughly discussed. The author suggests use of artemisimine and its derivatives as a very promising antimalarial drug. She also stresses the possibility of the application of new antimalaria vaccine against P. falciparum blood states, presently assayed in the country as an additional tool in malaria control programs.

  1. Nostalgic Venezuela. Reelection, rupture and revolution

    2017-09-01

    Full Text Available The Republic of Venezuela was an oasis in Latin America, a stable, democratic and prosperous country for several decades until the coming of the 1980s’ crisis. The new context and the erosion of traditional actors forced profound political changes. The crisis, the adjustments made during the 1990s and the population’s hopes of one day returning to the path of prosperity generated increasingly radical policy responses. This article seeks to analyse the political responses of the Venezuelan people to the challenges posed by their new socioeconomic reality and how these connect with visions derived from past experience and the approach to the roles of state and leader. It also explores the frustration caused by failure to meet their expectations, leading to the election of increasingly radical options.

    Each day cities inhabitants are exposed to visual pollution. This work assess the environmental impact caused by visual pollution in public spaces, using as a case of study a mixed-use neighborhood in San Cristobal, the capital of Tachira state, Venezuela. Such assessment was made using a qualitative approach, where special emphasis was paid to the perception of these impacts by a purposive sample of users of this area. The compilation and analysis of information reveal the main visual pollutants existing in these public spaces where, in addition to outdoor advertising, overhead wires, rubbish, graffiti, vacant land, among others, cars and outdoor kiosks. Neighborhood users are sensitive to the presence of visual pollutants, which affects them physically and psychologically, as well as for the visual quality of their environment. Such signs were used to guide a qualitative appraisal of environmental impacts generated by these circumstances and to propose policies to mitigate them.

  4. Notes about Alta Vista in Chalchihuites, Zacatecas

    The Tropic of Cancer is a parallel located at the latitude of 23°26'16''. This imaginary line extends across northern Mexico from the southernmost point of the Baja California Peninsula, to the Gulf of Mexico, passing through the states of Baja California Sur, Sinaloa, Durango, Zacatecas, San Luis Potosí, Nuevo León and Tamaulipas. The Tropic of Cancer marks the northernmost position of the sun at its midday zenith, which takes place in the Summer solstice. On this day, the sun's rays hit the earth's surface vertically along the entire length of this latitude, which was supposed to be significant for the priest/astronomers of ancient times, who dedicated themselves to observing the apparent movements of the sun. It so happens that Alta Vista in Zacatecas, corresponds to the westernmost peak where this phenomenon can occur, although the date of the zenith's course differs depending on the latitude of each position and so various archaeoastronomical specialists stress how the ancient indigenous cultures, at least those dating from Mexico's Classical period, valued this finding in developing their calendars. On the other hand, the research contributes new elements for discussion because it presents a calendar of the horizon, based on of the highest peaks of the Sierra Prieta mountain range ranging from the archaeological sites of El Chapín, Cerro Pedregoso, to the excavations at El Picacho Pelón (peak El Pelón).

    The Alberta Large-area Time-coincidence Array (ALTA) experiment uses a number of scintillation detector systems to form a sparse very large area cosmic air-shower detection array. An important scientific goal of the ALTA collaboration is to search for coincidences in the ALTA array due to large area cosmic ray phenomena. A local cosmic ray event, determined by a coincidence of the triplet of cosmic ray detectors forming a local detector system, is time stamped with a temporal coordinate obtained from a GPS receiver. The readout of the data, the local coincidence and the GPS time stamp are all performed in the local readout crate. This time stamp, along with the local shower direction is used to search for coincidences within the large area array. Using two GPS receivers and duplicate sets of ALTA electronics the timing resolution of the GPS time difference between sites was estimated to be 16 ns.

    Full Text Available Los debates sobre la democracia en la Venezuela de hoy carecen de una definición común sobre el tema, sobre cómo estudiarlo, e incluso respecto a qué es democracia. El régimen ha sido descrito de muchas formas: democracia participativa, híbrido, mixto, personalista, populista, iliberal, autoritarismo competitivo. El objetivo de este trabajo es determinar el nivel de calidad de la democracia en Venezuela, en el marco de una concepción procedimental de la democracia. La evaluación empírica de cinco dimensiones de calidad de la democracia (decisión electoral, participación, respuesta a la voluntad popular, rendición de cuentas y soberanía revela un nivel bajo en conjunto, con escasa variación entre 2005 y 2010. Los escenarios posibles luego de las elecciones de 2012 incluyen: reforzamiento de las tendencias autoritarias, militarización abierta, liberalización política con fortalecimiento institucional, o volatilidad duradera con conflicto polarizado y debilidad institucional. La salud del presidente Chávez afectará estos escenarios, dado su carácter de factor central unificador de su movimiento y del régimen.Discussions of democracy in contemporary Venezuela lack a settled definition of the subject, how to study it, or indeed of what counts as «democracy» in the first place. The regime has been described as everything from participatory democracy, hybrid, mixed, and personalist to populist, illiberal, or no longer democratic but rather competitive authoritarian. The goal of this article is to measure the quality of democracy in Venezuela, within the terms of a procedural concept of democracy as detailed in our earlier work. Empirical measurement of the quality of democracy on five dimensions (electoral choice, participation, responsiveness, accountability, sovereignty reveals a low level overall and deep institutional weakness under a personalist leadership, with little change from 2005 to 2010.

  11. Tertiary evolution of the northeastern Venezuela offshore

    Ysaccis B., Raul

    1998-12-01

    On the northeastern offshore Venezuela, the pre-Tertiary basement consists of a deeply subducted accretionary complex of a Cretaceous island arc system that formed far to the west of its present location. The internal structure of this basement consists of metamorphic nappes that involve passive margin sequences, as well as oceanic (ophiolitic) elements. The Tertiary evolution of the northeastern Venezuela offshore is dominated by Paleogene (Middle Eocene-Oligocene) extension and Neogene transtension, interrupted by Oligocene to Middle Miocene inversions. The Paleogene extension is mainly an arc-normal extension associated with a retreating subduction boundary. It is limited to the La Tortuga and the La Blanquilla Basins and the southeastern Margarita and Caracolito subbasins. All of these basins are farther north of and not directly tied to the El Pilar fault system. On a reconstruction, these Paleogene extensional systems were located to the north of the present day Maracaibo Basin. By early Miocene the leading edge of the now overall transpressional system had migrated to a position to the north of the Ensenada de Barcelona. This relative to South America eastward migration is responsible for the Margarita strike-slip fault and the major inversions that began during the Oligocene and lasted into the Middle Miocene. The Bocono-El Pilar-Casanay-Warm Springs and the La Tortuga-Coche-North Coast fault systems are exclusively Neogene with major transtension occurring during the Late Miocene to Recent and act independently from the earlier Paleogene extensional system. They are responsible for the large Neogene transtensional basins of the area: the Cariaco trough, the Northern Tuy-Cariaco and the Paria sub-basins, and the Gulf of Paria Basin. This latest phase is characterized by strain-partitioning into strike slip faults, a transtensional northern domain and a transpressional southern domain that is responsible for the decollement tectonics and/or inversions of the

    Venezuela had the highest number of human malaria cases in Latin American before 1936. During 1891–1920, malaria was endemic to >600,000 km2 of this country; malaria death rates led to major population decreases during 1891–1920. No pathogen, including the influenza virus that caused the 1918 pandemic, caused more deaths than malaria during 1905–1945. Early reports of malaria eradication in Venezuela helped spark the world’s interest in global eradication. We describe early approaches to malaria epidemiology in Venezuela and how this country developed an efficient control program and an approach to eradication. Arnoldo Gabaldón was a key policy maker during this development process. He directed malaria control in Venezuela from the late 1930s to the end of the 1970s and contributed to malaria program planning of the World Health Organization. We discuss how his efforts helped reduce the incidence of malaria in Venezuela and how his approach diverged from World Health Organization guidelines.

    Onchocerciasis is caused by Onchocerca volvulus and transmitted by Simulium species (black flies). In the Americas, the infection has been previously described in 13 discrete regional foci distributed among six countries (Brazil, Colombia, Ecuador, Guatemala, Mexico and Venezuela) where more than 370,000 people are currently considered at risk. Since 2001, disease control in Venezuela has relied on the mass drug administration to the at-risk communities. This report provides empirical evidence of interruption of Onchocerca volvulus transmission by Simulium metallicum in 510 endemic communities from two Northern foci of Venezuela, after 10-12 years of 6-monthly Mectizan (ivermectin) treatment to all the eligible residents. In-depth entomologic and epidemiologic surveys were serially conducted from 2001-2012 in selected (sentinel and extra-sentinel) communities from the North-central (NC) and North-east (NE) onchocerciasis foci of Venezuela in order to monitor the impact of ivermectin treatment. From 2007-2009, entomological indicators in both foci confirmed that 0 out of 112,637 S. metallicum females examined by PCR contained L3 infection in insect heads. The upper bound of the 95% confidence intervals of the infective rate of the vector reached values below 1% by 2009 (NC) and 2012 (NE). Additionally, after 14 (NC) and 22 (NE) rounds of treatment, the seasonal transmission potential (±UL CIs) of S. metallicum was under the critical threshold of 20 L3 per person per season.

    Arístides Marquez

    Full Text Available Abstract The carbon regeneration in the water column of the Cariaco Basin (Venezuela was investigated using a regression model of total alkalinity (TA and the concentration of total inorganic carbon (TCO2. Primary productivity (PP was determined from the inorganic carbon fraction assimilated by phytoplankton and the variation of the 22 and 23ºC isotherm was used as an indicator of coastal upwelling. The results indicate that CO2 levels were lowest (1962 µmol/kg at the surface and increased to 2451 µmol/kg below the oxic-anoxic redox interface. The vertical regeneration distribution of carbon was dominated (82% by organic carbon originating from the soft tissue of photosynthetic organisms, whereas 18% originated from the dissolution of biogenic calcite. The regeneration of organic carbon was highest in the surface layer in agreement with the primary productivity values. However, at the oxic-anoxic interface a second more intense maximum was detected (70-80%, generated by chemotrophic respiration of organic material by microorganisms. The percentages in the anoxic layers were lower than in the oxic zone because aerobic decomposition occurs more rapidly than anaerobic respiration of organic material because more labile fractions of organic carbon have already been mineralized in the upper layers.

    Full Text Available Recientemente el Ministerio del Poder Popular para la Educación convocó a una Consulta Nacional por la Calidad Educativa, acto en el cual el Ministro expresó: “es para lograr que Venezuela sea un país potencia”. Otro funcionario sentenció, “somos el segundo país en América Latina y quinto en el mundo con mayor presencia de jóvenes en recintos universitarios”. En efecto, la matrícula universitaria creció 203% entre el año 1997 y el 2010; en 1997 había 756.000 estudiantes universitarios inscritos, cifra que aumentó hasta 2.294.000 en el año 2010. Estadísticas que generan muchas interrogantes, una de ellas relacionada con la “calidad educativa”; lo cual nos obliga a recordar que hay programas e indicadores confiables para un auténtico diagnóstico del rendimiento de la educación, particularmente de primaria y secundaria. Sin embargo, quienes han conducido la educación en nuestro país, nunca evaluaron seriamente su rendimiento; peor aún, en la última década se ha sacrificado la calidad educativa en aras de la cantidad de matrícula

El método Locati, descrito en esta nota, está basado en la Ley de Miner de daño acumulado y en las curvas de Wohler del material ensayado. Permite calcular, con precisión suficiente, las tensiones límites de fatiga al 50%. Así, los valores obtenidos, en ensayos a dos millones de ciclos, para carriles sin soldar (Sf = 353 MPa, carriles soldados con precalentamiento de oxipropano (Sf = 225 MPa y carriles soldados con precalentamiento de propano-aire inducido (Sf = 210 MPa son muy similares y aceptables a los estipulados por los métodos de determinación del límite de fatiga según norma europea. Debido a la comodidad, rapidez y bajo coste del método Locati resulta, en nuestra opinión, muy adecuado para el control de calidad de los procesos de soldadura aluminotérmica en vigor, de carriles de alta resistencia.

    Full Text Available This paper suggests a variation of the IMO index (Okun's Misery Index, adapting it to markets with these characteristics, adding the ESI level (Employment in the Informal Sector to the unemployment level. This research compares the evolution of several standard misery indexes in several zones during the last decades, with emphasis on the case of Venezuela, for which the new proposed index is also estimated. Results show improvement in the well-being of groups of countries under study, compared to the deterioration of the indicator in Venezuela. In general terms, the IMO is controlled by unemployment, except in Venezuela. However, preponderance of inflation over unemployment in this country seems to occur by the underestimate that the unemployment rate has on the Venezuelan labor market situation.

    Full Text Available The focus of this article is on what role, if any, oil has on Venezuela's instability. When trying to explain why a resource-rich country experiences slow or negative growth, experts often point to the resource curse. The following pages explore the traditional theory behind the resource curse as well as alternative perspectives to this theory such as ownership structure and the correlation between oil prices and democracy. This article also explores the various forms of instability within Venezuela and their causes. Finally, the article looks at President Hugo Chavez's political and economic policies as well as the stagnation of the state oil company, Petroleos de Venezuela (PDVSA. This article dispels the myth that the resource curse is the source of destabilization in many resource dependent countries. Rather than a cause of instability, this phenomenon is a symptom of a much larger problem that is largely structural.

    2014-01-01

    The structure of the gold mining industry in Venezuela has changed significantly since 1999 as a result of Government policy changes and industry response to these changes. This report documents the policy decisions that have affected the mining industry, discusses the response of the industry on a site by site basis, and suggests possible effects of these changes on the global economy. For the short term, at least, it appears that these changes have made Venezuela a more difficult place to invest for U.S. and Canadian companies, while investment by Chinese entities has been encouraged.

  14. Interrupting Chagas disease transmission in Venezuela.

    Science.gov (United States)

    Aché, A; Matos, A J

    2001-01-01

    The interruption of vectorial transmission of Chagas disease in Venezuela is attributed to the combined effects of ongoing entomoepidemiological surveillance, ongoing house spraying with residual insecticides and the concurrent building and modification of rural houses in endemic areas during almost five decades. The original endemic areas which totaled 750,000 km(2), have been reduced to 365,000 km(2). During 1958-1968, initial entomological evaluations carried out showed that the house infestation index ranged between 60-80%, the house infection index at 8-11% and a house density index of 30-50 triatomine bugs per house. By 1990-98, these indexes were further reduced to 1.6-4.0%, 0.01-0.6% and 3-4 bugs per house respectively. The overall rural population seroprevalence has declined from 44.5% (95% C.I.: 43.4-45.3%) to 9.2% (95% C.I.: 9.0-9.4%) for successive grouped periods from 1958 to 1998. The annual blood donor prevalence is firmly established below 1%. The population at risk of infection has been estimated to be less than four million. Given that prevalence rates are stable and appropriate for public health programmes, consideration has been given to potential biases that may distort results such as: a) geographical differences in illness or longevity of patients; b) variations in levels of ascertainment; c) variations in diagnostic criteria; and d) variations in population structure, mainly due to appreciable population migration. The endemic areas with continuous transmission are now mainly confined to piedmonts, as well as patchy foci in higher mountainous ranges, where the exclusive vector is Rhodnius prolixus. There is also an unstable area, of which landscapes are made up of grasslands with scattered broad-leaved evergreen trees and costal plains, where transmission is very low and occasional outbreaks are reported.

The results indicate that the country has a high potential of AE, that the hidroenergy in great scale is the unique one with an important participation in the energy system, and that the solar energy and the eolic are those of greater possibility of development. However, an assembly of factors impede the development in firm of the AE, fundamentally related to its historic condition of producer and consumer of fuel fossil in great scale at low cost.

    2012-07-01

    Arid zones of northern Venezuela are represented by isolated areas, important from an ornithological and ecological perspective due to the occurrence of restricted-range species of birds. We analysed the prevalence and molecular diversity of haemosporidian parasites of wild birds in this region by screening 527 individuals (11 families and 20 species) for parasite mitochondrial DNA. The overall prevalence of parasites was 41%, representing 17 mitochondrial lineages: 7 of Plasmodium and 10 of Haemoproteus. Two parasite lineages occurred in both the eastern and western regions infecting a single host species, Mimus gilvus. These lineages are also present throughout northern and central Venezuela in a variety of arid and mesic habitats. Some lineages found in this study in northern Venezuela have also been observed in different localities in the Americas, including the West Indies. In spite of the widespread distributions of some of the parasite lineages found in northern Venezuela, several, including some that are relatively common (e.g. Ven05 and Ven06), have not been reported from elsewhere. Additional studies are needed to characterize the host and geographical distribution of avian malaria parasite lineages, which will provide a better understanding of the influence of landscape, vector abundance and diversity, and host identity on haemosporidian parasite diversity and prevalence.

    The data of accidents caused by snakebites in Venezuela, registered at the morbidity statistics of the Direction of Epidemiology and Strategic Analysis of the Ministry of Health and Social Development were analyzed. During the years of 1996-2004, 53,792 snakebites were registered in Venezuela (5,976 cases average per year), with a higher incidence during the year 2004 (7,486 incidents). Zulia reported the highest frequency of all the states (5,975 cases); meanwhile the Midwestern region, constituted by Lara, Portuguesa, Falc6n and Yaracuy states, had a higher morbidity for snake bites. The highest incidence, distributed per states was registered in Cojedes, during the year 2001, with 228.72 cases per 100,000 inhabitants. When it was determined by regions, the highest incidence occurred during the year 2004 at los Llanos with 63.81 per 100,000 inhabitants. The median of the incidence rate for Venezuela during the period was of 21.46 accidents per 100,000 inhabitants. The classification of the endemic areas for ophidism, according to the percentiles 23, 50, 75 and 90, organized the country in: (a) states and regions of very high endemicity, (b) high endemicity, (c) middle, (d) low and (e) very low endemicity. These epidemiological data indicated that the accidents caused by snakes constitute a collective health problem in Venezuela.

    CYP2D6 is an important cytochrome P450 enzyme that plays an important role in the metabolism of about 25% of currently prescribed drugs. The presence of polymorphisms in the CYP2D6 gene may modulate enzyme level and activity, thereby affecting individual responses to pharmacological treatments. The most prevalent diseases in the admixed population from Venezuela are cardiovascular and cancer, whereas viral, bacterial and parasitic diseases, particularly malaria, are prevalent in Amerindian populations; in the treatment of these diseases, several drugs that are metabolized by CYP2D6 are used. In this work, we reviewed the data on CYP2D6 variability and predicted metabolizer phenotypes, in healthy volunteers of two admixed and five Amerindian populations from Venezuela. The Venezuelan population is very heterogeneous as a result of the genetic admixture of three major ethnical components: Europeans, Africans and Amerindians. There are noticeable inter-regional and inter-population differences in the process of mixing of this population. Hitherto, there are few published studies in Venezuela on CYP2D6; therefore, it is necessary to increase research in this regard, in particular to develop studies with a larger sample size. There is a considerable amount of work remaining before CYP2D6 is integrated into clinical practice in Venezuela.

Esta investigación enfoca al MERCOSUR como un proceso de integración que busca la conformación de un mercado común por medio de la eliminación de barreras arancelarias y para arancelarias. En ese sentido el presente estudio considera la participación de la República Bolivariana de Venezuela como posible miembro pleno del bloque, también se analiza el escenario asimétrico que caracteriza a Venezuela para su ingreso al MERCOSUR, donde se destacan las asimetrías de Venezuela para con los países miembros del bloque sureño, considerando de esta forma los potenciales beneficios y costos que tendrá para Venezuela la inclusión real al conglomerado de países que integran el MERCOSUR. Se ha basado en un trabajo de tipo documental, donde se realiza un análisis sobre la inclusión de Venezuela al esquema integracionista. Como conclusión es importante destacar que el objetivo de MERCOSUR  se basa en crear una zona de libre comercio para beneficio de los países que integran América del Sur.

    Full Text Available Identificar e estimular a criança com altas habilidades/superdotação tem se constituído em um desafio para educadores e psicólogos. Muitas concepções acerca do fenômeno das altas habilidades têm sido propostas por estudiosos desde o início do século XX. Uma das concepções mais conhecidas sobre o superdotado é de que seria aquele indivíduo que se sai bem nos testes de inteligência, ou que apresenta um desempenho intelectual superior. Entretanto, superdotação não pode ser considerada exclusivamente como sinônimo de QI alto. Concepções atuais sobre este fenômeno têm chamado a atenção para a importância de se considerar outros aspectos como influência do ambiente, sorte, autoconceito positivo, motivação e, especialmente, a criatividade. Dois importantes objetivos da educação do aluno com altas habilidades/superdotação são: (a desenvolver talentos e habilidades, auxiliando estes indivíduos a atualizarem seu potencial e se tornarem criativos, e (b habilitá-los a darem contribuições criativas à sociedade. O objetivo deste artigo é, portanto, discutir a importância da criatividade no desenvolvimento de altas habilidades/superdotação. Palavras-chave: Superdotação. Altas Habilidades. Criatividade.

Dentro de los principales parámetros determinados se encontraban: grado de daño, número de insectos posados sobre plantas de arroz, porcentaje de mortalidad de sogata en estado adulto, número de huevos y se calculó un índice de tolerancia con base en la biomasa. Los resultados mostraron que los genotipos de arroz evaluados poseen diferentes combinaciones en cuanto a los mecanismos de resistencia, así como el grado de su efecto. El testigo ‘Bluebonnet 50’ se mantuvo consistentemente susceptible en las evaluaciones y el testigo resistente ‘Makalioka’ fue el único genotipo que presentó alta antixenosis y alta antibiosis para sobrevivencia y oviposición. El resto de los genotipos presentaron un menor o mayor grado de resistencia de tipo antixenosis y antibiosis para sobrevivencia y oviposición. Se identificó el genotipo ‘FD0241-M-17-6-1-1-1-1’ con posible tolerancia al daño directo de sogata.

    Honkoop, J.

    2009-07-15

    The author describes the decline of Venezuela's oil industry as well as President Chavez' reaction to Venezuela's budgetary crisis. Politicization, falling investment and the obligation to take upon itself a plethora of social spending have left national oil company Petroleos de Venezuela, S.A. unable to produce efficiently and maintain production levels. Falling oil production and lower oil prices have in turn left president Hugo Chavez unable to spread the wealth to Venezuela's poor and he is searching desperately for ways to extract yet more from Venezuela's dysfunctional economy. As funds run out, Venezuela's expensive foreign policy, supporting regional allies, in particular Cuba, and seeking to export anywhere but the United States, proves overly expensive. Venezuela's impoverished masses, still supportive of Chavez during February's elections, may become less so as funds for social programmes run out. For Chavez it is a time for making choices... otherwise the people of Venezuela will choose for him. [Dutch] De auteur beschrijft de teruggang van de olie-industrie van Venezuela en de reacties van president Chavez op de budgettaire crisis in Venezuela. Politisering, dalende investeringen en de verplichtingen m.b.t. de overvloed aan sociale uitgaven zorgen er voor dat de nationale oliemaatschappij Petroleos de Venezuela niet in staat is om efficient te produceren en de productie op peil te houden. Dalende olie-productie en lagere olieprijzen zorgen er ook voor dat de president niet in staat is om de rijkdom te verdelen over de armen in Venezuela. Hij is op zoek naar manieren om meer te halen uit de slecht functionerende economie. Zijn dure buitenlandse Venezuela beleid, onder meer door ondersteuning van regionale bondgenoten, in het bijzonder Cuba, en het zoeken naar export mogelijkheden, behalve naar de USA, pakt fiancieel gezien slecht uit.

    1991-09-01

    This study of migration to Venezuela from the Dominican Republic used sociological and anthropological techniques to study fragmentation and regrouping of families before and after migration, family subsistence strategies, entry into the labor force, and mutual aid networks among migrants. A 44-item questionnaire was administered in 1987 to 50 heads of households born in the Dominican Republic and residing in Venezuela with their families for at least 1 year. The survey took place in metropolitan Caracas. Its findings were complemented by use of traditional participant-observation. 43 respondents were male and 7 were female. 30 were married, 1 divorced, 16 in consensual unions, and 2 widowed. Respondents' ages ranged from 26 to 57 years. 38 had resided permanently in their place of birth before migrating to Venezuela. 36 had lived in Venezuela for 5-10 years and 9 for 11-15 years. 39 stated that their principal reason for coming to Venezuela was to find employment. 36 entered on tourist visas, 11 on transient visas, and 2 with no documentation. 29 entered the country alone, 12 came with spouses, and 8 with most of their family group. Only 3 planned a future move within Venezuela. The migrants were of relatively low educational status. 16 had incomplete and 19 complete primary educations and 11 had some degree of secondary education. 41 were employed at the time of the survey, 5 were unemployed and 3 were temporarily disabled. 16.3% were vendors, 12.2% were office workers, 8.2% were transport workers, 8.2% were artisans or operators, 8.2% were in domestic service, and 12.2% were in other personal services. 22 worked in enterprises with fewer than 5 workers or were self-employed and only 6 worked in enterprises with 21 or more employees. 11 had had 3 jobs since their arrival, in Venezuela, 8 had had 4, and 25 had had 5 or more. 16 migrants had found their jobs through a direct search, 16 had obtained them through recommendations of friends or relatives, and 2 were

    of newly generated outer zones due to quick cooling. The emplacement age for the dykes may be early Cenozoic, as for similar basement rocks from the Gulf of Venezuela and the Guajira Peninsula. A felsic-gneiss xenolith enclosed in the dykes contains inherited Proterozoic zircons (1200-950 Ma) with rims of Permian age (270.2±4.1 Ma). Thus, the inherited older ages detected in the feldspar-gneiss unit, the later dykes, and the xenolith indicate the occurrence of Grenvillian crust in Northwestern South America. The Permian ages obtained in the Paraguaná Peninsula are similar to ages reported for the Mérida Andes, Santa Marta Massif, Perijá Range, Orchila Island, northern part of the Maracaibo Basin (Toas Island), northwestern Falcon Basin. Therefore, the Permian magmatic event may have been related to an active margin during the construction of Pangaea, caused by the subduction of oceanic crust under the northwestern corner of South America.

    Streptomyces venezuelae YJ028, bearing a deletion of the entire biosynthetic gene cluster encoding the pikromycin polyketide synthases and desosamine biosynthetic enzymes, was used as a bioconversion system for combinatorial biosynthesis of glycosylated derivatives of tylosin. Two engineered deoxysugar biosynthetic pathways for the biosynthesis of TDP-3-O-demethyl-D-chalcose or TDP-Lrhamnose in conjunction with the glycosyltransferaseauxiliary protein pair DesVII/DesVIII were expressed in a S. venezuelae YJ028 mutant strain. Supplementation of each mutant strain capable of producing TDP-3-O-demethyl- D-chalcose or TDP-L-rhamnose with tylosin aglycone tylactone resulted in the production of the 3-O-demethyl- D-chalcose, D-quinovose, or L-rhamnose-glycosylated tylactone.

  16. [Recent evolution of natality and fertility in Venezuela].

    Science.gov (United States)

    Picouet, M R

    1977-01-01

    Venezuela, like the majority of Latin American countries, has experienced an important decrease in fertility rate since 1960; it was 48/1000 in 1954, the highest level ever, but only 36.6/1000 in 1975. This phenomenon implies the intervention of new factors which affected birth rate. Birth underegistration in Venezuela has always been a problem; it has decreased from 8% in 1950, to 6% in 1971, but it is still necessary to make corrections in the observed birth rate to have a figure nearer to reality. Thus, while observed birth rate was 45.9/1000 in 1960, and 36.6 in 1975, the estimated birth rate was 47.7 and 38.1 in the same years. The computation of age-specific fertility rate shows an increase up to 1960, a stabilization between 1960 and 1967, and a progressive decrease after 1968. An interpretation of the recent evolution in birth and fertility rate must take into consideration the number of women exposed to the risk of pregnancy, the changes in rate of marriage, and especially the changes in reproductive behavior. Family planning programs have been available in Venezuela since 1963, and there are now about 150 clinics which provide contraceptive information and services. However, the female population covered by such programs is only 12%; this means that numerous women seek contraception outside of organized programs, and that, indeed, birth control precedes years of the diffusion of contraceptive methods. With an estimated birth rate of 38.1/1000 in 1975, Venezuela still has one of the highest natality rates in the world.

    Full Text Available El delito de secuestro es un flagelo social que ha experimentado mutaciones en el tiempo. El año 2009 terminó con una cifra sin precedentes en cuanto a los secuestros reportados en Venezuela. Los datos aportados por los organismos oficiales revelan que durante el 2008 hubo 537 secuestros, lo cual representa un aumento de 52% respecto al total del 2007, mientras que en el 2009 la cifra se incrementó en un 62,82%, en relación con el año anterior. Esta investigación tiene como objetivo describir el delito de secuestro en Venezuela, con especial referencia al Estado Zulia, población fronteriza limítrofe con Colombia. Para ello se emplea una metodología de tipo documental- descriptiva. Se revela que no existen esquemas predefinidos que permitan caracterizar este tipo penal, pues, tal y como ha venido sucediendo, es susceptible de llevarse a cabo en cualquier momento y circunstancia, no de modo exclusivo en sujetos de alto estatus socioeconómico, sino con mínimos medios para responder a las exigencias de los plagiarios; de aquí la proliferación de la modalidad del llamado secuestro exprés. El delito de secuestro en Venezuela ha cambiado en forma notable sus patrones: de ser un delito predominantemente político, fronterizo y ejecutado por grupos organizados, ha pasado a ser uno de objetivos sobre todo económicos, urbano, y ejecutado con un fin de lucro por la delincuencia común. En verdad, el Estado Zulia sigue repuntando en la lista de los estados con mayor incidencia de este delito en Venezuela, pero no es el principal, pues ha sido desplazado en posicionamiento por otras urbes del país, encabezadas en la actualidad por la ciudad capital de Caracas.

During the study period 1,792 patients, 350 (20%) of which were lithiasis cases were seen in the Urology Unit. 2.80 per thousand of the studied population had urolithiasis-related signs. Incidence is higher in males than in females, as well as in patients with prior lithiasic diseases, surgery and urinary infections. Urinary infection was present in 20% of patients. Nine percent of patients had some type of associated urinary malformation. The most frequent mineral composition of the lithiasis was: Calcium oxalate (52%), uric acid (20%) and oxalate plus uric acid (9%).

    Full Text Available El propósito de este artículo es hacer una breve revisión histórica de la política universitaria en Venezuela. La política universitaria en Venezuela tiene como antecedente la Universidad Colonial, pero surge más concretamente a partir de la reforma de 1827. Las universidades son un ente fundamentalmente político. Las universidades no son solamente espacios para el adiestramiento y formación de los profesionales que requiere la nación. Las universidades reflejan a la sociedad a la que pertenecen. Cuando se refiere a la política universitaria venezolana estamos haciendo referencia a las políticas de los respectivos estados y gobiernos en relación al papel que debe jugar las universidades en el desenvolvimiento del país. Pretendemos responder a las preguntas: ¿cómo ha sido la relación entre los gobiernos y las universidades?, ¿Ha existido una política universitaria en Venezuela?, ¿Cómo han evolucionado los principios de equidad, democracia y autonomía en las universidades?, ¿Quién manda en las universidades?¿Qué y quiénes investigan?, ¿Cómo y quién mide la cal

  11. Risk, Activism, and Empowerment: Women's Breast Cancer in Venezuela.

    Eid, Mahmoud; Nahon-Serfaty, Isaac

    2015-01-01

    The prevalence of breast cancer in Venezuela is particularly alarming, which is attributed to healthcare inequalities, low health literacy, and lagging compliance with prevention methods (i.e., screening and mammography). While the right to health is acknowledged by the Venezuelan constitution, activism beyond governmental confines is required to increase women's breast cancer awareness and decrease mortality rates. Through the development of social support and strategic communicative methods enacted by healthcare providers, it may be possible to empower women with the tools necessary for breast cancer prevention. This paper discusses issues surrounding women's breast cancer, such as awareness of the disease and its risks, self-advocacy, and the roles of activists, healthcare providers, and society. Specifically, it describes a four-year action-oriented research project developed in Venezuela, which was a collaborative work among researchers, practitioners, NGOs, patients, journalists, and policymakers. The outcomes include higher levels of awareness and interest among community members and organizations to learn and seek more information about women's breast cancer, better understandings of the communicated messages, more media coverage and medical consultations, increasing positive patient treatments, expansion of networking of NGOs, as well as a widely supported declaration for a national response against breast cancer in Venezuela.

    In 1999, newly-elected Venezuelan President Hugo Chávez initiated a far-reaching social movement as part of a political project known as the Bolivarian Revolution. Inspired by the democratic ideologies of Simón Bolívar, this movement was committed to reducing intractable inequalities that defined Venezuela's Fourth Republic (1958-1998). Given the ambitious scope of these reforms, Venezuela serves as an instructive example to understand the political context of social inequalities and population health. In this article, we provide a brief overview of the impact of egalitarian policies in Venezuela, stressing: (a) the socialist reforms and social class changes initiated by the Bolivarian Movement; (b) the impact of these reforms and changes on poverty and social determinants of health; (c) the sustainability of economic growth to continue pro-poor policies; and (d) the implications of egalitarian policies for other Latin American countries. The significance and implications of Chávez's achievements are now further underscored given his recent passing, leading one to ask whether political support for Bolivarianism will continue without its revolutionary leader.

  13. Violence in Venezuela: oil rent and political crisis

    2006-06-01

    Full Text Available This article analyzes the changes in violence in Venezuela during the last forty years. It links the ups and downs of the oil revenues and the political crisis of the country to the changes in the homicide rates, which increased from 7 per 100 thousand inhabitants in 1970 to 12 in 1990, 19 in 1998 and 50 in 2003. The article characterizes Venezuela as a rentist society and shows its trajectory from rural violence to the beginning of urban violence, the guerilla movements of the 60s, the delinquent violence related to the abundance of oil revenues and the violence during the popular revolt and the sackings of 1989 in Caracas. After this, we analyze the coups d'état of 1992 and the influence the political violence exerted upon criminal violence. We describe the political and party changes in the country, their influence upon the stabilization of homicide rates since the mid-90s and their remarkable increase during the H. Chávez government. The article finishes with an analysis of the current situation, the official prohibition to publish statistics on homicides and with some thoughts about the perspective of greater violence in Venezuela.

    This map is one of a series of 1:500,000-scale maps that, along with several other products, stems from a cooperative agreement between the U.S. Geological Survey (USGS) and the Corporacion Venezolana de Guayana, Tecnica Minera, C.A. (TECMIN), a Venezuelan Government-owned mining and mineral exploration company. The agreement covered cooperative work carried out in the Precambrian Shield of southern Venezuela during 1987-1991 and included a geologic and mineral resource inventory, technology transfer, and scientific training (Wynn and others, in press). The Precambrian Guayana Shield (Escudo de Guyana, not to be confused with the neighboring country of Guyana) includes some of the oldest known rocks in the world (Mendoza, 1977) and also covers parts of neighboring Guyana, Surinam, French Guiana, Columbia, and Brazil. In Venezuela, it underlies most of Bolivar state and all of the Amazonas Federal Territory (see index map).

    This report summarizes the data available on radioactive source materials in Los Estados Unidos de Venezuela accumulated by geologists of the Direccions Tecnica de Geolgia and antecedent agencies prior to June 1951, and the writers from June to November 1951. The investigation comprised preliminary study, field examination, office studies, and the preparation of this report, in which the areas and localities examined are described in detail, the uranium potentialities of Venezuela are summarized, and recommendations are made. Preliminary study was made to select areas and rock types that were known or reported to be radioactive or that geologic experience suggests would be favorable host for uranium deposits, In the office, a study of gamma-ray well logs was started as one means of amassing general radiometric data and of rapidly scanning many of ye rocks in northern Venezuela; gamma-ray logs from about 140 representative wells were examined and their peaks of gamma intensity evaluated; in addition samples were analyzed radiometrically, and petrographically. Radiometic reconnaissance was made in the field during about 3 months of 1951, or about 12 areas, including over 100 localities in the State of Miranda, Carabobo, Yaracuy, Falcon, Lara, Trujillo, Zulia, Merida, Tachira, Bolivar, and Territory Delta Amacuro. During the course of the investigation, both in the filed and office, information was given about geology of uranium deposits, and in techniques used in prospecting and analysis. All studies and this report are designed to supplement and to strengthen the Direccion Tecnica de Geologias's program of investigation of radioactive source in Venezuela now in progress. The uranium potentialities of Los Estados de Venezuela are excellent for large, low-grade deposits of uraniferous phospahtic shales containing from 0.002 to 0.027 percent uranium; fair, for small or moderate-sized, low-grade placer deposits of thorium, rare-earth, and uranium minerals; poor, for

    Full Text Available La finalidad del presente artículo es analizar la eficiencia en la productividad, desde la perspectiva del cliente interno y externo, en las empresas recicladoras del plástico en el departamento de la Guajira-Colombia. Se determina primero la repercusión del cliente interno, que es el personal que labora en las empresas recicladoras, el cual se considera el receptor primario de la visión, misión y estrategias formuladas para lograr la satisfacción del cliente externo. En este orden de ideas, cada empleado es un cliente interno conforme recibe su insumo, información, tarea, entre otros; en tanto que al cliente externo, que es el punto vital para cualquier institución, se le conoce también desde el punto de vista del ciclo comercial como grupo objetivo que pasa por consumidor potencial, luego eventual y, por último, en habitual. En este caso, se evidencia que los recursos y logística que poseen los clientes internos para satisfacer las necesidades, deseos y expectativas de su cliente externo expresan un moderado nivel de productividad. A la vez, se generan lineamientos estratégicos de mercadeo para potencializar el proceso productivo de este sector empresarial.

    Financial information from TransAlta Corp. was presented along with a review of their operations throughout 2000 and a summary of the how the electric utility is doing in terms of power generation, independent power producers, transmission and energy marketing. The utility has changed from a regulated vertically integrated utility into one of Canada's largest non-regulated electric power generators. The utility sold its retail businesses in Alberta and New Zealand and now focuses on coal and hydro generation, gas generation, high-voltage transmission and energy marketing. The newly constructed Centralia, Washington generation facility was brought on line with 1,340 MW in May 2000, on time and on budget. This was the platform to diversify their generation into the United States. The utility reported a solid financial year with $177.9 million in earnings from continuing operations, an 83 per cent increase from 1999, driven mostly by the results of Centralia and power marketing and trading businesses. A financial loss was suffered when the Wabamum power plant in Alberta was shut down for several months to repair a boiler. The utility made excellent progress toward their goal of 15,000 megawatts by 2005 by starting with the construction of what will be one of Canada's largest cogeneration facilities at Sarnia, Ontario. TransAlta also commissioned a 360 MW cogeneration facility at Poplar Creek at Suncor's Fort McMurray oil sand facility.

    Petroleos de Venezuela S.A. (PDVSA) has been meeting during the past two years with a considerable number of companies (groups) with a view to possible associations for the reactivation of known fields, joint activities in barely explored areas and the exploitation, refining, upgrading and marketing of crudes from the Orinoco Belt holder of immense reserves of extra-heavy crudes and bitumens. In Venezuela, a new approach to the oil business is under way. On January 1976, the law nationalizing the Venezuelan oil industry became effective establishing that the government retains the sole rights to the country's petroleum industry. However, Article 5 of the law made provision for associations in cases considered to be of [open quotes]National Interest.[close quotes] PDVSA became the wholly government-owned holding entity, encompassing 26 subsidiaries and affiliates. Other energy segments, particularly coal and petrochemicals, were not included in the law and since 1984 several associations with non-governmental entities have been established in Venezuela and very valuable experience has been garnered. Similarly, partnerships and acquisitions have been made in Europe and USA, mostly in refining, through PDVSA. The international petroleum industry foresees a modest, but steady increase in production during the coming decade, particularly in the second half of the nineties. This effect, added to the globalization concept, is making the traditional vertically integrated oil companies look for diverse [open quotes]lateral[close quotes] associations between groups, private and/or state owned with common interests, that will give greater security to sources of supply and market share.

    "This paper presents six indirect techniques for estimating the degree of death coverage as applied to vital statistics information in Venezuela between 1960 and 1982, collected by two public institutions, namely, the 'Oficina Central de Estadistica e Informatica' (OCEI) and the Ministry of Health and Social Assistance (MSAS).... The results show remarkable improvements in the death registry coverage for both institutions, that amount to 97 or 98 per cent at the beginning of the 80's. Nevertheless, great differences can be observed between them regarding both structure and volume of deaths by sex and age." Among the problems discussed are the impact of immigration and errors in age reporting. (SUMMARY IN ENG) excerpt

    This paper reports that with the exception of Venezuela, the U.S. is likely to import much oil from South American countries through 2010, the General Accounting Office reports. GAO, a congressional watchdog agency, noted the U.S. imports about 4% of its oil from Colombia, Ecuador, and Trinidad and Tobago and possibly could import from Argentina, Bolivia, Brazil, Chile, and Peru in the future. It the the eight countries' crude oil reserves are expected to increase about 30% by 2000, then slide about 2% by 2010. Their oil production is expected to climb about 21% over 1990 by 2000, then level off until 2010

    1999-12-01

    Survey of larval habitats of anopheline mosquitoes was conducted in Ocamo in the State of Amazonas, southern Venezuela. The sampled habitats belonged to three different hydrological types: lagoons (26 habitats), forest pools including flooded forest (16 habitats), and forest streams (4 habitats). Out of 46 habitats surveyed, 31 contained anopheline larvae. Six species were found: Anopheles darlingi, Anopheles triannulatus, Anopheles oswaldoi, Anopheles peryassui, Anopheles punctimacula, and Anopheles mediopunctatus. Anopheles triannulatus was the most abundant species. Significantly higher numbers of anopheline larvae, in general, and of An. triannulatus specifically were found in lagoons with submersed macrophytes and sparse emergent graminoids than in forest pools with detritus.

    Full Text Available En este trabajo se estudia el fenómeno inflacionario venezolano reciente, caracterizado como un caso de “inflación moderada”. En él se relaciona esta situación con el problema de la debilidad institucional, el déficit de credibilidad de las autoridades, lo cual ha llevado a un importante uso del impuesto inflacionario como mecanismo de financiamiento del gasto público. Así mismo se señala el papel desempeñado por la inercia en la permanencia de la inestabilidad de los precios en Venezuela.

    Full Text Available International election monitoring has been touted as a regional norm in the Western hemisphere, but recent reforms in Venezuela and Nicaragua substituted a diminished international role of electoral accompaniment. This article traces the initial acceptance and later limitation of international election monitoring in those countries to explore whether the change constitutes norm localization or norm defection. It concludes that the norm is not as well institutionalized in the hemisphere as conventionally thought, and that models need to assess together national and international monitoring capacities.

    After the publication of the SISRA (CERESIS-1985) regional project, a unified catalog of seismic parameters and intensities for South America, researchers in historical seismicity have continued advancing on different scales in the area of this study of seismic hazard. The most important initiatives carried out in this area in Colombia and Venezuela can be grouped as follows: a) Reviews of destructive earthquakes in national and international historic archives, principally by Altez and FUNVISIS in Venezuela and Espinosa, Salcedo, and Sarabia et al in Colombia, leading to the preparation of seismologic catalogues, scientific and dissemination articles, reports, books, among others. b) Organization and systematization of historic information to develop public domain data bases and information, specifically the Historic Seismologic Teleinformation System in Venezuela, carried out between 2004 and 2008 under the coordination of Christl Palme and accessible on-line: http://sismicidad.ciens.ula.ve. As well, the "Historia Sísmica de Colombia 1550-1830" (Seismic History in Colombia 1550-1830) data base, in CD-ROM, by Espinosa Baquero (2003) and the historic seismicity information system of Colombia (Servicio Geológico Colombiano-Universidad Nacional de Colombia), published on the internet in 2012: http://agata.ingeominas.gov.co:9090/SismicidadHistorica/. c) Macroseismic studies for the development of intensity attenuation equations and the quantification and revaluation of basic historic earthquake parameters using isoseismal maps (Rengifo et al., Palme et al., Salcedo et al., among others) and procedures such as Boxer and Bakun & Wentworth (Palme et al., Dimaté, among others), which have produced significant changes in the parameters of some of the large earthquakes. d) Symposiums of researchers to promote interest and development in the discipline, including Jornadas Venezolanas de Sismología Histórica (Venezuelan Congress of Historical Seismology), held

    Uranium exploration started in Venezuela in 1951. The activities began with enthusiasm but interest waned because of the unfavourable economic conditions of the uranium market. In 1975, with the establishment of the National Council for the Development of the Nuclear Industry, emphasis was once again placed on exploration for radioactive minerals. Systematic exploration began 18 months ago, and so far exploratory targets have been found in phosphate rocks in Tachira state and in Palaeozoic granites at El Baul (Cojedes state); very favourable occurrences have been encountered in the Precambrian in Merida and Bolivar states, and in continental Tertiary rocks in Trujillo state.

Los ecosistemas de la alta montaña no han sido ajenos a esta realidad, y particularmente en las zonas de Páramo del Cauca, el intento por favorecer la prevalencia de un modelo altamente productivo e intensivo en el uso del suelo ha conllevado al detrimento de la diversidad socio-ecológica, la rápida expansión de la frontera agropecuaria en áreas estratégicas, la pérdida del conocimiento tradicional sobre el uso de la tierra y el bajo rendimiento de los cultivos que ha implicado mayor incorporación de fertilizantes al suelo amenazando estos sistemas vulnerables en la alta montaña. Sin embargo, es común encontrar en diferentes localidades paramunas caucanas comunidades indígenas y campesinas que reconocen la necesidad de cambiar los sistemas productivos que han venido empleando debido a la disminución de la fertilidad del suelo que limita la comercialización de sus productos y a la problemática ambiental asociada, en este sentido, el acompañamiento institucional en este proceso es vital para favorecer la implementación de procesos sostenibles de forma integral.

    Full Text Available Salt production in the Mixteca Alta is a traditional means of production from prehispanic period, which, despite the economic transformation processes in the colonial period, remained significant features of the traditional process, based on the documented similar models from other productive regions in Mexico. The salt in the novohispanic period was considered a major consumption economic asset due to its use in production processes for the production of new economic products that supported the economy of preindustrial societies (Terán, 2011, p. 71; Williams, 2008. Technology refers to the knowledges for solving human needs arising lifestyle of the cultural groups that develop them. The resources of the natural environment underpin the means of labor that man requires to perform its activities, including economic. The means of production and production processes are technological developments, which involve elements of tangible and intangible order. The study of work processes for salt extraction, are significantly related to the processes of technological evolution that man has developed for the use of natural resources. The economic activities of the primary sector are examples of how humans culturally and economically were inserted in the natural environment (Malpica, 2008, p. 59. This analysis presents a historiographical approach to the study of the processes and the technology required for the extraction of salt in the Mixteca Alta.

    A severe outbreak of Paralytic Shellfish Poisoning (PSP) occurred in Manzanillo and Guayacán, northwestern coast of Margarita Island, Venezuela, between August and October 1991. A bloom of dinoflagellates including Prorocentrum gracile, Gymnodinium catenatum and Alexandrium tamarense seemed to be responsible for this outbreak. Levels of PSP toxins in mussels (Perna perna) exceeded the international safety limit of saxitoxin, 80 microg STX/100 microg meat. PSP toxin values varied between 2548 and 115 microg STX/100 g meat in Manzanillo, and between 1422 and 86 microg STX/100 g meat in Guayacán. At both locations, the highest levels were detected in August, when 24 patients exhibited typical symptoms of PSP toxicity after consuming cooked mussels (16 required hospitalization). A high pressure liquid chromatographic (HPLC) procedure was recently used on the 1991 samples. The major toxin detected in samples of both locations was decarbamoyl saxitoxin (dcSTX), but low concentrations of saxitoxin were also found in Manzanillo samples. Gonyautoxins GTX1, GTX2 and GTX3 were detected only at Guayacán, while in both locations, decarbamoylgonyatouxin (dcGTX2,3) toxins were detected. These findings represent the first time that causative toxins of PSP in Venezuela have been chemically identified, and confirm the presence of dcSTX and dcGTX in mussels from the Caribbean Sea. The presence of dcSTX and dcGTX in shellfish is indicative that Gymnodinium catenatum was a causative organism for outbreak of PSP.

    The enzymatic modification of aminoglycosides by aminoglycoside-acetyltransferases (AAC), aminoglycoside-adenyltransferases (AAD), and aminoglycoside-phosphotransferases (APH), is the most common resistance mechanism in P. aeruginosa and these enzymes can be coded on mobile genetic elements that contribute to their dispersion. One hundred and thirty seven P. aeruginosa isolates from the University Hospital, Cumana, Venezuela (HUAPA) were evaluated. Antimicrobial susceptibility was determined by the disk diffusion method and theaac, aadB and aph genes were detected by PCR. Most of the P. aeruginosa isolates (33/137) were identified from the Intensive Care Unit (ICU), mainly from discharges (96/137). The frequency of resistant P. aeruginosaisolates was found to be higher for the aminoglycosides tobramycin and amikacin (30.7 and 29.9%, respectively). Phenotype VI, resistant to these antibiotics, was the most frequent (14/49), followed by phenotype I, resistant to all the aminoglycosides tested (12/49). The aac(6´)-Ib,aphA1 and aadB genes were the most frequently detected, and the simultaneous presence of several resistance genes in the same isolate was demonstrated. Aminoglycoside resistance in isolates ofP. aeruginosa at the HUAPA is partly due to the presence of the aac(6´)-Ib, aphA1 andaadB genes, but the high rates of antimicrobial resistance suggest the existence of several mechanisms acting together. This is the first report of aminoglycoside resistance genes in Venezuela and one of the few in Latin America.

    We investigated the periodicity of Plasmodium vivax and P. falciparum incidence in time-series of malaria data (1990-2010) from three endemic regions in Venezuela. In particular, we determined whether disease epidemics were related to local climate variability and regional climate anomalies such as the El Niño Southern Oscillation (ENSO). Malaria periodicity was found to exhibit unique features in each studied region. Significant multi-annual cycles of 2- to about 6-year periods were identified. The inter-annual variability of malaria cases was coherent with that of SSTs (ENSO), mainly at temporal scales within the 3-6 year periods. Additionally, malaria cases were intensified approximately 1 year after an El Niño event, a pattern that highlights the role of climate inter-annual variability in the epidemic patterns. Rainfall mediated the effect of ENSO on malaria locally. Particularly, rains from the last phase of the season had a critical role in the temporal dynamics of Plasmodium. The malaria-climate relationship was complex and transient, varying in strength with the region and species. By identifying temporal cycles of malaria we have made a first step in predicting high-risk years in Venezuela. Our findings emphasize the importance of analyzing high-resolution spatial-temporal data to better understand malaria transmission dynamics. Copyright © 2013 Elsevier B.V. All rights reserved.

    Chagas disease is an endemic zoonosis native to the Americas and is caused by the kinetoplastid protozoan parasite Trypanosoma cruzi. The parasite is also highly genetically diverse, with six discrete typing units (DTUs) reported TcI – TcVI. These DTUs broadly correlate with several epidemiogical, ecological and pathological features of Chagas disease. In this manuscript we report the most comprehensive evaluation to date of the genetic diversity of T. cruzi in Venezuela. The dataset includes 778 samples collected and genotyped over the last twelve years from multiple hosts and vectors, including nine wild and domestic mammalian host species, and seven species of triatomine bug, as well as from human sources. Most isolates (732) can be assigned to the TcI clade (94.1%); 24 to the TcIV group (3.1%) and 22 to TcIII (2.8%). Importantly, among the 95 isolates genotyped from human disease cases, 79% belonged to TcI - a DTU common in the Americas, however, 21% belonged to TcIV- a little known genotype previously thought to be rare in humans. Furthermore, were able to assign multiple oral Chagas diseases cases to TcI in the area around the capital, Caracas. We discuss our findings in the context of T. cruzi DTU distributions elsewhere in the Americas, and evaluate the impact they have on the future of Chagas disease control in Venezuela. PMID:22745843

    In January of this year, Venezuela captured the attention of the international energy community by welcoming back the foreign oil companies that, 20 years earlier, it had shut out of the country by nationalizing the hydrocarbon sector. The tool used to attract that attention, a new exploration bidding round, is the most publicized event staged to date in the country's aperture process. However, it is only the latest in a series of steps taken by officials to bring international oil and gas companies back to Caracas. Venezuela's physical attraction is easily understood. The country possesses roughly one-half of Latin America's (including Mexico) 125 billion bbl of established, conventional crude oil reserves, plus an estimated 300 billion bbl of additional, nonconventional reserves in the ultra-heavy crude belt of the Orinoco basin. Averaging 2.8 million bpd in 1996, Venezuelan crude production represents over 35% of regional oil output. Natural gas reserves total 138 Tcf, or just over one-half of the region's total reserves of 274 Tcfg. Annual gas output averages just under 5 Tcf, of which roughly 30% is reinjected as part of tertiary oil recovery schemes. This paper reviews the incentives, deregulation, and government policies to restore the oil and gas industry to the country

    Based on the information available on fishes of the order characiforms of Venezuela a biogeographical analysis was performed to explore the relative importance of the processes that may have contributed to the establishment of current distribution patterns of the Venezuelan continental ichthyofauna. Geographic and phylogenetic information available for this group of fishes was analyzed by parsimony analysis of endemicity (PAE) and brooks parsimony analysis (BPA). PAE uncovered the western plains and southern Amazonas as areas of endemism. BPA, using the phylogenetic information of seven genera, showed a general pattern with two major clades (Caribbean + Maracaibo) and (Rio Negro + Orinoco river) + Paria + Valencia) + Cuyuni), where the proposed hypothesis highlights a dispersion event from the Rio Negro basin to the Orinoco river. The results indicate that the plains-Amazonas region, where the amazon biota mixed with that of the incipient Orinoco s biota, contains the largest species richness, areas of endemism, and well as many speciation events with posterior dispersion to other regions of Venezuela. The biota of the northern coastal region in turn seems rather governed by punctual vicariant speciation processes, which may have been conditioned by the historical isolation of the basins draining this region.

    Full Text Available This paper addresses a core puzzle: why is continued citizen mobilization accompanied by growing disempowerment of those same citizens? Why do movements fail, leaders burn out and members disperse, and what are the implications of this organizational failure for demo¬cratic representation? Our consideration of the issues is rooted in a close examination of urban movements, mobilization, empowerment and disempowerment in the recent experience of Venezuela and Perú. The puzzle that concerns us is of course not limited to these two countries: it is common to all the Andean republics, and in different ways, to much recent experience of urban mobilization in Latin America and beyond. After a brief account of urban citizen move¬ments and politics in our two cases, we outline general reflections on the nature of empowerment and disempowerment, on the peculiar combination of strengths and weaknesses that mark many contemporary movements. A close examination of types of movements and their links with poli¬tical parties and protest follows. The character of city life is important here. We close with analysis of recent waves of urban mobilization in Perú (that sparked the ouster of president Alberto Fujimori and in Venezuela (both for and against president Hugo Chávez Frías, and with reflections on the likely future of empowerment and disempowerment for urban citizens and the implications of this perspective for democratic representation

    Full Text Available El presente artículo presenta una revisión documental de los principales textos legales que amparan el funcionamiento del Gobierno Electrónico en Venezuela, vigentes al finalizar el primer semestre de 2009. Los resultados sugieren que existen dos grandes bloques legales que sustentan el uso de las TIC por el Gobierno, y tienen que ver, por un lado, con aquellas dirigidas a dotar de eficacia jurídica a las manifestaciones de voluntad por vía electrónica y, por otro, con aquellas pensadas para conseguir eficiencia en el cumplimiento de las funciones del Estado. El análisis de los distintos instrumentos que regulan la implementación de las TIC revela que Venezuela cuenta con una base jurídica en la materia sólida y  avanzada, por lo que la mayoría de las deficiencias que existen se deben más bien a la implementación. Se adopta un concepto amplio de gobierno electrónico, expandiéndolo a todas las ramas del poder público en tanto y en cuanto sus órganos se relacionen con el ciudadano o entre si. Por último se hace un llamado al poder judicial de manera de que se incorpore de manera plena las ventajas de los recursos electrónicos al proceso judicial.

    Free-living amoebae of Acanthamoeba genus are opportunistic pathogens distributed worldwide. Strains included in this genus are causative agents of a fatal encephalitis and a sight-threating keratitis in humans and other animals. In this study, 550 clinical samples which were collected between 1984 and 2014 from different patients with suspected infections due to Acanthamoeba were initially screened for the presence of this amoebic genus at the Laboratorio de Amibiasis-Escuela de Bioanálisis at the Universidad Central de Venezuela. Samples were cultured in 2% Non-Nutrient agar plates seeded with a layer of heat killed Escherichia coli. From the 550 clinical samples included in this study, 18 of them were positive for Acanthamoeba genus after culture identification. Moreover, positive samples were confirmed after amplification of the Diagnostic Fragment 3 (DF3) of the Acanthamoeba18S rDNA genus and sequencing was carried out in order to genotype the isolated strains of Acanthamoeba. Furthermore, the pathogenic potential of the strains was checked by performing thermotolerance and osmotolerance assays. Sequencing of the DF3 region resulted in the identification of genotype T4 in all the isolated strains. Moreover, most isolates were thermotolerant or both thermotolerant and osmotolerant and thus were classified as potentially pathogenic strains. To the best of our knowledge, this is the first report on the molecular characterization at the genotype level of Acanthamoeba strains in Venezuela.

    Full Text Available In Venezuela, mammals represent an important group of wildlife with high anthropogenic pressures that threaten their permanence. Focused on the need to generate baseline information that allows us to contribute to document and conserve the richness of local wildlife, we conducted a mammalogical inventory in Yurubí National Park, located in Yaracuy State in Venezuela. We carried out fieldworks in three selected vegetation types: an evergreen forest at 197m, a semi-deciduous forest ranging between 100-230m, and a cloud forest at 1 446m. We used Victor, Sherman, Havahart and pitfall traps for the capture of small non-volant mammals and mist nets for bats. In addition, we carried out interviews with local residents and direct-indirect observations for medium-large sized mammals. At least 79 species inhabit the area, representing 28% of the species recorded for the North side of the country. Chiroptera (39 spp., Carnivora (13 spp. and Rodentia (9 spp. were the orders with the highest richness, as expected for the Neotropics. The evergreen forest had the greatest species richness (n=68, with a sampling effort of 128 net-hours, 32 bucket-days, 16 hours of observations, and three persons interviewed, followed by cloud forest (n=45 with 324 net-hours, 790 traps-night, 77 bucket-days, 10 hours of observations, and one person interviewed. The lowest richness value was in the semi-deciduous forest (n=41, with 591 traps-night, 15 net-hours, 10 hours of observations and three persons interviewed.

  14. The Crustal Structure and Seismicity of Eastern Venezuela

    Science.gov (United States)

    Schmitz, M.; Martins, A.; Sobiesiak, M.; Alvarado, L.; Vasquez, R.

    2001-12-01

    Eastern Venezuela is characterized by a moderate to high seismicity, evidenced recently by the 1997 Cariaco earthquake located on the El Pilar Fault, a right lateral strike slip fault which marks the plate boundary between the Caribbean and South-American plates in this region. Recently, the seismic activity seems to migrate towards the zone of subduction of the Lesser Antilles in the northeast, where a mb 6.0 earthquake occurred in October 2000 at 120 km of depth. Periodical changes in the seismic activity are related to the interaction of the stress fields of the strike-slip and the subduction regimes. The seismic activity decreases rapidly towards to the south with some disperse events on the northern edge of the Guayana Shield, related to the Guri fault system. The crustal models used in the region are derived from the information generated by the national seismological network since 1982 and by microseismicity studies in northeastern Venezuela, coinciding in a crustal thickness of about 35 km in depth. Results of seismic refraction measurements for the region were obtained during field campains in 1998 (ECOGUAY) for the Guayana Shield and the Cariaco sedimentary basin and in 2001 (ECCO) for the Oriental Basin. The total crustal thickness decreases from about 45 km on the northern edge of the Guayana Shield to some 36 km close to El Tigre in the center of the Oriental Basin. The average crustal velocity decreases in the same sense from 6.5 to 5.8 km/s. In the Cariaco sedimentary basin a young sedimentary cover of 1 km thickness with a seismic velocity of 2 km/s was derived. Towards the northern limit of the South-American plate, no deep seismic refraction data are available up to now. The improvement of the crustal models used in that region would constitute a step forward in the analysis of the seismic hazard.

    2011-01-01

    Samples from rodents captured on a farm in Venezuela in February 1997 were tested for arenavirus, antibody against Guanarito virus (GTOV), and antibody against Pirital virus (PIRV). Thirty-one (48.4%) of 64 short-tailed cane mice (Zygodontomys brevicauda) were infected with GTOV, 1 Alston’s cotton rat (Sigmodon alstoni) was infected with GTOV, and 36 (64.3%) of 56 other Alston’s cotton rats were infected with PIRV. The results of analyses of field and laboratory data suggested that horizontal transmission is the dominant mode of GTOV transmission in Z. brevicauda mice and that vertical transmission is an important mode of PIRV transmission in S. alstoni rats. The results also suggested that bodily secretions and excretions from most GTOV-infected short-tailed cane mice and most PIRV-infected Alston’s cotton rats may transmit the viruses to humans.

    During the period January to December 1987, rotaviruses were obtained from infants hospitalized with acute gastroenteritis in Cumaná, Venezuela, and were compared by analysis of the migration of their double-stranded ribonucleic acid (RNA) genome segments in polyacrylamide gel electrophoresis. Rotavirus RNA was detected in 87 (17.03%) of 511 faecal samples, and at least 12 different electropherotypes were recognized throughout the period of study. Of the rotavirus positive samples, 86 (98.85%) had a "long" electrophoretic pattern characteristic of human rotavirus subgroup 2. The incidence of rotavirus infection was statistically related with the age, sex, and nutritional status of the pediatric patients for epidemiological purposes. This statistical relation was very significant with the age and the nutritional status of the patients but not with their sex.

    The environmental radiation levels have been determined in Venezuela by means of different techniques including the passive dosimeters and the alpha and gamma dosimetry besides the gross alpha/beta counting. The most important conclusion is that the presence of artificial radionuclides (Cesium-137, Beryllium-7 and Cadmium-109) was observed in different environmental samples and in food considered contaminant. The values of gamma levels are between 28 and 40 mGy/day and the mean value of radon concentration in closed environment is 36 Bq/m 3 ; the higher values of a factor 10 have been measured in the Andes region. The 20% of analysed drinking water has a concentration of alpha radionuclides emitters less than 0.005 Bq/l and only the 8% is greater than 0.450 Bq/l. (authors). 6 refs., 1 fig

    1992-01-01

    The Orinoco Belt in Venezuela contains huge deposits of a bitumen that is complex to handle and refine into lighter hydrocarbon fractions. These deposits are in the early commercialization stage, being marketed as an emulsion with 30% water as a boiler fuel. The fuel is similar to oil in heating value (about 18,100 BTU/lbm) and ash (less than 0.4%). It has an extremely high carbon to hydrogen ratio, a parameter that is important in MHD for electrical conductivity. In this paper, the authors evaluate the potential for this bitumen as a fuel for an MHD Steam Combined Cycle Power Plant. An experimental program to demonstrate the merit of the bitumen as an MHD fuel and validate the calculations is suggested

    Energy Technology Data Exchange (ETDEWEB)

    Pereira, N.; Bonduki, Y.; Perdomo, M.

    1996-12-31

    The Government of Venezuela ratified the United Nations Framework Convention on Climate Change (UNFCCC) in December, 1994. The Convention requires all parties to develop and publish national inventories of anthropogenic greenhouse gas emissions (GHG) as well as national plans to reduce or control emissions, taking into account their common but differentiated responsibilities and their specific national and regional development priorities, objectives, and circumstances. Within this context, the Ministry of Environment and Renewable Natural Resources and the Ministry of Energy and Mines developed the `Venezuelan Case-Study to Address Climate Change`. The study was initiated in October 1993, with the financial and technical assistance of the Government of United States, through the U.S. Country Studies Program (USCSP), and the Global Environment Facility (GEF), through the United Nations Environment Programme (UNEP).

  12. What does the failure to reduce homicides in Venezuela teach?

    Directory of Open Access Journals (Sweden)

    Roberto Briceño-León

    2017-09-01

    Full Text Available This article addresses the paradox of increased homicides in Venezuela in a period of wealth and redistribution. To do so, theories that explain criminality through poverty and inequality are reviewed and refuted and weighed against theories of institutionalism. Thus, the article analyses the situation of homicides between 1985 and 2010 and establishes three periods in which the rules regulating access to a goods, b political power, and c social and penal control were broken. The theories are discussed with statistical information and interpreted within the economic and political context of the time. It is concluded that the reduction in homicides requires institutionalism based on sensitivity and certain formal and informal rules that allow the construction of legitimacy around social difference and punishment, and a citizens’ culture that favours social control by peers over penal control by the State.

  13. Estados Unidos y Venezuela: Una relación necesaria.

    Directory of Open Access Journals (Sweden)

    Carlos Romero.

    2002-09-01

    Full Text Available The author identifies Hugo Chavez's electoral victory and the implementation of a new type of democracy as two factors that transformed Venezuelan foreign policy, and in particular, the bilateral relationship with the United States. Chavez's international activism, in addition to his Bolivarian policy signaled a shift from "safe partner" to "partner with reservations" in the country's relations with Washington. Although Venezuela considered itself a Latin American showcase in previous years, the text argues that Chavez's populist tendencies, his critical posture towards the promotion of democracy and human rights, and his supposed links with Colombian guerrillas has led to a "wait-and-see" policy characterized by high levels of caution on the part of the United States.

  16. Embodying racism: race, rhinoplasty, and self-esteem in Venezuela.

    Science.gov (United States)

    Gulbas, Lauren E

    2013-03-01

    In this article, I examine how race motivates women's decisions to undergo aesthetic rhinoplasty in Caracas, Venezuela. Through a combination of cultural domain analysis and thematic analysis of qualitative interviews, I explore how the preference for whiteness and associated facial features dovetail with the aesthetic ideals promoted by cosmetic surgeons. Rhinoplasty is offered by physicians and interpreted by patients as a resolution to body dissatisfaction and low self-esteem. The clinical ethos of objectivity established by cosmetic surgeons fails to acknowledge how perceptions of the self and body are strongly tied to racial marginalization: patients' efforts to alter the nose reveal attempts to change not only how the body looks, but how it is lived. As a result, cosmetic surgery only acts as a stop-gap measure to heighten one's self-esteem and body image.

    Full Text Available Los pastos marinos son ecosistemas costeros de alta productividad, con gran diversidad y abundancia de peces, la cual es aprovechada por pescadores artesanales. En este estudio se analizó la estructura comunitaria íctica de praderas de Thalassia testudinum en Manzanillo (M y La Brea (LB, costa noroeste del Golfo de Cariaco, Venezuela. También, se realizaron muestreos mensuales (11-2006 al 10-2007, con la utilización de una red playera. Se capturaron 34 810 organismos agrupados en 13 órdenes, 36 familias y 83 especies. En ambas zonas, el número de especies fue similar, aunque el número de organismos vario, y se encontró para M un total de 55 especies y 13 210 organismos y para LB 58 especies y 21 600 organismos. Las especies más abundantes y de mayor biomasa en el área muestreada fueron: Nicholsina usta, Haemulon boschmae, H. steindachneri, Harengula jaguana, Halichoeres bivittatus y Hemiramphus brasiliensis. Los visitantes ocasionales fue el componente comunitario más frecuente con 59%, los cíclicos y los residentes permanentes obtuvieron 22 y 19%, respectivamente. En M la H’n fue de 1.71±0.64bits/ind; entretanto en LB fue 1.95±0.51bits/ind. Los valores de la diversidad estuvieron relacionados directamente con la equitabilidad e inversamente con la dominancia. Los bajos valores del índice de similaridad, entre localidades permite establecer que estas comunidades ícticas son disimiles, debido quizás a la estructuración de cada pradera de Thalassia y a la conectividad con otros sistemas.

    Full Text Available Las empresas familiares se han convertido en un importante motor de las economías a nivel mundial, representan el 90% del parque empresarial y contribuyen con el 50% del producto y el empleo (Gersick et al, 1997; Gallo, 1997; y Amat, 1998. Uno de los retos que debe afrontar este tipo de empresas es ser competitivas, para ello tendrán que adaptar su estructura organizativa, operativa y administrativa en procura de una mayor eficiencia y agilidad. Entre éstas, emerge el diseño organizativo como fundamental, ya que es el responsable de la configuración y forma de comportarse de una organización en pro de su estrategia y objetivos. De allí que el objetivo del presente trabajo sea determinar el tipo de diseño organizacional con el que operan las cadenas de hipermercados y supermercados familiares en Venezuela. Este estudio se desarrolla empleando un diseño de investigación no experimental de campo, con un tipo de estudio descriptivo, para lo cual se aplicó un cuestionario a los fundadores o sucesores de dichas empresas. Los resultados muestran comportamientos variables en materia de diseños organizativos, características cómo la formalización, especialización y coordinación relevantes para un cabal funcionamiento, no están claramente definidas; además de existir una alta tendencia a centralizar, en vez, de propiciar la descentralización en la toma de decisiones. Los diseños organizativos son parte del sistema de dirección y funcionamiento interno que contribuirá a la profesionalización empresarial, conjuntamente con las políticas de recursos humanos, las tecnologías de información y comunicación (TICs, y las estructuras de gobierno corporativo.

    Full Text Available El presente artículo tiene como objetivo explorar el modelo de Personalidad de Marca en Venezuela, a través del estudio propuesto por Aaker (1997 de los rasgos de personalidad, utilizando los centros comerciales como producto de referencia. La investigación de tipo exploratorio adoptó un muestreo no probabilístico por conveniencia. La muestra resultó de ciento sesenta y ocho personas (168 entre encuestas auto suministradas y vía correo electrónico. En el procesamiento de los datos se aplicó un análisis de Confiabilidad vía Alfa de Cronbach encontrándose que las dimensiones de personalidad de marca para Venezuela son: Emocionante (0.91, Sinceridad (0.83, Pasional (0.88 Pasividad (0.76 y Rudeza (0.68. Estos resultados revelaron importantes diferencias con un estudio previo realizado en el país. La causa puede deberse a la falta de un procedimiento muestral más representativo de ambos estudios, ya que hasta la fecha no se ha realizado un estudio de escala nacional para medir Personalidad de Marca. A pesar de ello, se consiguieron evidencias que los rasgos de personalidad alrededor de la dimensión “Emocionante” pudiesen ser explicativos de la personalidad del venezolano promedio, ya que además de su consistencia interna, presentan coincidencias con otros estudios empíricos de segmentación realizados en el país.

    Full Text Available The enzymatic modification of aminoglycosides by aminoglycoside-acetyltransferases (AAC, aminoglycoside-adenyltransferases (AAD, and aminoglycoside-phosphotransferases (APH, is the most common resistance mechanism in P. aeruginosa and these enzymes can be coded on mobile genetic elements that contribute to their dispersion. One hundred and thirty seven P. aeruginosa isolates from the University Hospital, Cumana, Venezuela (HUAPA were evaluated. Antimicrobial susceptibility was determined by the disk diffusion method and theaac, aadB and aph genes were detected by PCR. Most of the P. aeruginosa isolates (33/137 were identified from the Intensive Care Unit (ICU, mainly from discharges (96/137. The frequency of resistant P. aeruginosaisolates was found to be higher for the aminoglycosides tobramycin and amikacin (30.7 and 29.9%, respectively. Phenotype VI, resistant to these antibiotics, was the most frequent (14/49, followed by phenotype I, resistant to all the aminoglycosides tested (12/49. The aac(6´-Ib,aphA1 and aadB genes were the most frequently detected, and the simultaneous presence of several resistance genes in the same isolate was demonstrated. Aminoglycoside resistance in isolates ofP. aeruginosa at the HUAPA is partly due to the presence of the aac(6´-Ib, aphA1 andaadB genes, but the high rates of antimicrobial resistance suggest the existence of several mechanisms acting together. This is the first report of aminoglycoside resistance genes in Venezuela and one of the few in Latin America.

    Full Text Available This paper addresses a core puzzle: why is continued citizen mobilization accompanied by growing disempowerment of those same citizens? Why do movements fail, leaders burn out and members disperse, and what are the implications of this organizational failure for demo¬cratic representation? Our consideration of the issues is rooted in a close examination of urban movements, mobilization, empowerment and disempowerment in the recent experience of Venezuela and Perú. The puzzle that concerns us is of course not limited to these two countries: it is common to all the Andean republics, and in different ways, to much recent experience of urban mobilization in Latin America and beyond. After a brief account of urban citizen move¬ments and politics in our two cases, we outline general reflections on the nature of empowerment and disempowerment, on the peculiar combination of strengths and weaknesses that mark many contemporary movements. A close examination of types of movements and their links with poli¬tical parties and protest follows. The character of city life is important here. We close with analysis of recent waves of urban mobilization in Perú (that sparked the ouster of president Alberto Fujimori and in Venezuela (both for and against president Hugo Chávez Frías, and with reflections on the likely future of empowerment and disempowerment for urban citizens and the implications of this perspective for democratic representationEste artículo plantea un puzzle principal: ¿por qué la movilización ciudadana continuada viene acompañada de un crecimiento del desempoderamiento de estos mismos ciudadanos? ¿Por qué los movimientos fracasan, los líderes se desgastan y los miembros se dispersan, y cuáles son las implicaciones del fracaso organizativo para la representación democrática?

We will be publishing a Spanish translation this month in Medicina Social. We present here the abstract of the article. We encourage readers to read the English original which is available at: www.medicc.org/mediccreview/. The issue is entitled: Teaching for Health Equity: Changing Paradigms of Medical Education. National Training Program for Comprehensive Community Physicians, Venezuela Introduction: Through the 1990s, wide disparities in health status were recorded in Venezuela, a mirror of poor social conditions, decreasing investment in the public health sector and a health workforce distribution unable to meet population health needs or to staff effective, accessible public health services. Venezuelans’ health status deteriorated as a result. In 2003-2004, the Venezuelan government launched Barrio Adentro, a new national public health model aimed at assuring primary health care coverage for the entire population of an estimated 26 million. Cuban physicians staff Barrio Adentro clinics, mainly in poor neighborhoods, until enough Venezuelan physicians can be trained to fill the posts. Intervention: Cuban experience with community-oriented medical education and global health cooperation was drawn upon to develop curriculum and provide faculty for the new National Training Program for Comprehensive Community Physicians, begun in 2005 in cooperation with six Venezuelan universities. The program differs from previous Venezuelan medical education models by adopting a stated goal of training physicians for public service, recruiting students who had no previous opportunity for university-level education, and concentrating the weight of their training on a service- and community-based model of education, relying on practicing physician-tutors. Results: Over 20,000 students have been enrolled in three years. The six

    En el marco de un proyecto de investigación-acción que se implementó en Venezuela de 2009 a 2013 se buscó empoderar (empower) a activistas sociales y pacientes en la lucha contra el cáncer de mama (CM). Este proyecto se puso en marcha en un contexto de alta polarización política y social en el marco de la llamada «Revolución bolivariana». A partir de una perspectiva ecológica de la comunicación y el activismo en salud, que integra los niveles interpersonal, grupal y social, se celebraron una serie de actividades orientadas a desarrollar las habilidades de vocería de ciudadanos, especialmente de mujeres, y ampliar las redes de cooperación entre diversos sectores, al mismo tiempo que se perfiló una visión consensuada entre actores sociales e institucionales sobre una respuesta nacional contra el CM. Una comunicación horizontal y participativa permitió que se escuchara la voz de actores usualmente marginalizados en las políticas sanitarias. PMID:27867911

    Only two species of the microteiid lizard genus Euspondylus (E. acutirostris and E. phelpsorum) had been reported from Venezuela. New records of the poorly known gymnophthalmid lizard Euspondylus acutirostris are reported extending its known range along the Coastal Range and Sierra de Aroa (north-central Venezuela) and Sierra de San Luis (northwestern Venezuela), all records occurring at the cloud forest above 1000 m. Seven body measurements were included and morphological variation is described based on at least 17 new specimens. Sexual dimorphism is determined in, at least, eight characteristics of size and squamation. Specimens were found in epiphytic bromeliads and the ground. The populations from Sierra de Aroa and Sierra de San Luis (only one specimen known from each locality), differ from those of the Coastal Range (supposedly the nominal population) in some morphological and coloration features, suggesting that the former two could represent different taxonomical entities. A new species of Euspondylus is described based on a female (taken within a bromeliad) from Cerro El Humo, Sucre, northeastern Venezuela. It differs from congeners mainly by having keeled scales on the limbs and a very acute snout.

    The ocular manifestations and sequelae of Zika virus infection are not well known. Recently, the World Health Organization changed the declaration of Zika as a public health emergency and designated the viral outbreak and related microcephaly clusters as a long-term program of work. This change indicates the urgent need to evaluate and document ophthalmic manifestations in patients for timely management of this disease. In addition, confirmation whether the public health problem in Brazil extends to other regions in South America is needed. To report the ocular manifestations of congenital Zika syndrome with microcephaly in Colombia and Venezuela. This prospective case series included 43 patients from 2 ophthalmic centers in Colombia and Venezuela who underwent evaluation from October 1, 2015, through June 30, 2016, and were clinically diagnosed with congenital Zika syndrome. Twenty patients were Hispanic; 13, African; 8, white; and 2, Native American. Ophthalmic and systemic evaluations and serologic testing were performed on all infants. Patients underwent external ocular examination and dilated ophthalmoscopy. Serologic testing ruled out toxoplasmosis, rubella, cytomegalovirus, syphilis, and human immunodeficiency virus. Ophthalmic manifestations of congenital Zika syndrome. Of the 43 patients included in this series (28 female and 15 male), the mean (SD) age at examination was 2.1 (1.5) months. The mothers of all the children had no ophthalmic findings and did not report ocular symptoms during pregnancy. All patients had bilateral ophthalmic manifestations. Optic nerve findings included hypoplasia with the double-ring sign, pallor, and increased cup-disc ratio in 5 patients (11.6%). Macular abnormalities included mild to severe pigment mottling in 27 patients (63%) and lacunar maculopathy in 3 (6.9%). Chorioretinal scarring was present in 3 patients (7%).

    The Tucupita Field has an area of 73,51 Km2, is located between the states of Monagas and Delta Amacuro, geologically is located at the greater Temblador area in the Eastern Venezuela Basin, where the Oficina Formation's sands represent the main hydrocarbons reservoirs. From the results of the seismic reprocessing realized by Fusion Petroleum Technologies, Inc., the structural model of this field was done as initial step to the geocellular model of the Oficina-40 Reservoir, which was defined as a Faulted Relay Ramp, where the normal faults are dominant with NE-SW orientation Introduction The Tucupita Field is a mature oilfield at the greater Temblador area, however most of the wells were completed in the upper sands, therefore the main study is focused in the geological characterization of the Oficina-40 Reservoir's lower sands, starting by the structural model Previous Studies 1. Proyecto Tucupita 3D The seismic data of the Tucupita Field were adquired in 1996 by Western Atlas of Venezuela for the Benton Vinccler Company. The UTM coordinates of the wells used in this project, have been taken to make this geological model 2. Soporte Geofísico Integrado The seismic project Tucupita was processed by Fusion Petroleum Technologies Inc., in Houston and consisted of reprocessing and pre-stack migration in time (PSTM) and pre-stack migration in depth (PSDM), this data belong to the Petrodelta Company Based on the regional stratigraphy, were validated the "picks" to make the structural sections to support research with hard data. After, it proceeded to interpret the structural style of the field from the seismic amplitude cube. Then, it was done the faults modelling and the stratigraphic horizons to carry out the geocellular model Three structural sections were realized, which was interpreted like a faulted monocline, whose peak is located southward, where justly the wells are located.

    Full Text Available El Joropo es una expresión de arte popular en permanente evolución, originalmente una fiesta campesina o pueblerina que integra poesía, canto, música y danza en un sistema de creatividad improvisatoria sobre estructuras establecidas y parámetros definidos de estilo. El Joropo se caracteriza por un sistema de estructuras cristalizadas a lo largo de la historia a partir de canciones y danzas tradicionales que se erigieron en formas musicales, sirviendo como base para a variantes en la letra, o convirtiéndose en formas puramente instrumentales. El Joropo es una tradición que abarca casi la totalidad del territorio venezolano y al menos la cuarta parte del territorio colombiano. En Venezuela el Joropo es considerado el baile nacional por excelencia y existen tres tipos de Joropo clasificados por regiones con importantes variantes de instrumentación y estilo: el Joropo Oriental, el Joropo Central y el Joropo Llanero. Solamente el Joropo Llanero, extendido alrededor de la cuenca central del Orinoco, es común a Colombia y Venezuela, siendo el más difundido de todos, tanto por la amplia discografía y radiodifusión como por la abundancia de festivales, concursos y torneos que involucran a ambos países. Además es notable el auge y desarrollo urbano que ha tenido esta música en los últimos años en las respectivas capitales. Sus orígenes se remontan a las músicas ibéricas del Siglo XVII y XVIII, tales como el múltiple Fandango, las Folías, Peteneras, Jotas y Malagueñas andaluzas, sazonadas con la influencia de ocho siglos de dominación árabe y posteriormente transformadas en América con el mestizaje de elementos africanos e indígenas, bajo el sol abrasador de la Cuenca del Orinoco y la vastedad infinita de sus horizontes y llanuras. Los antecesores del Joropo incluyen la música de marineros y trovadores que llega en los galeones provenientes de España, transformándose en música arraigada en el suelo americano y dando lugar a

    The Caribbean waters of Venezuela are composed by a large variety of habitats, with over 2800 km of coastline, islands, and islets. This area is a transitional zone between two main biogeographic provinces, the Caribbean and the Brazilian, separated by the fresh water outflows of the Orinoco and Amazon rivers, and is therefore expected to be an area of high species diversity. However, concerning the study of molluscs, Venezuela is probably the poorest known region in the Caribbean. The best compilation of opisthobranch species known in Venezuela was produced almost a decade ago, mentioning the occurrence of 57 species, plus seven determined only to genus level. In this work, 134 species are reported for Venezuela (71 are illustrated), representing about 40 % of the entire diversity of opisthobranchs known in the Caribbean. Among the species occurring in Venezuela, 49 have here the southern limit of their distribution range and only one the northern limit. Forty-six species are recorded for the first time to the country and one is a new record for the Caribbean Sea, namely Placida cremoniana. In addition, the distribution and ecology of the species are given based in literature and new data.

    2006-01-01

    Full Text Available Introduction. Intestinal parasitic infections, especially due to helminths, increase anemia in pregnant women. The results of this are low pregnancy weight gain and IUGR, followed by LBW, with its associated greater risks of infection and higher perinatal mortality rates. For these reasons, in the setting of no large previous studies in Venezuela about this problem, a national multicentric study was conducted. Methods. Pregnant women from nine states were studied, a prenatal evaluation with a coproparasitological study. Univariated and multivariated analyses were made to determine risk factors for intestinal parasitosis and related anemia. Results. During 19 months, 1038 pregnant women were included and evaluated. Intestinal parasitosis was evidenced in 73.9%: A lumbricoides 57.0%, T trichiura 36.0%, G lamblia 14.1%, E hystolitica 12.0%, N americanus 8.1%, E vermicularis 6.3%, S stercoralis 3.3%. Relative risk for anemia in those women with intestinal parasitosis was 2.56 ( P<.01 . Discussion. Intestinal parasitoses could be associated with conditions for development of anemia at pregnancy. These features reflect the need of routine coproparasitological study among pregnant women in rural and endemic zones for intestinal parasites. Further therapeutic and prophylactic protocols are needed. Additional research on pregnant intestinal parasitic infection impact on newborn health is also considered.

    The prevalence of porcine rotavirus infection was studied in 15 different herds located in the north-western region of Venezuela. The presence of rotavirus was studied by direct electron microscopy (EM) and by an enzyme-linked immunosorbent assay (ELISA). From 136 samples analyzed during the six months of the study (September 1983-February 1984), 38 (27.9%) were found to be positive for rotaviruses, with infection more common in animals that were 4-6 weeks old. Atypical rotaviruses were not detected in any of the samples examined. Most rotavirus positive specimens were subgrouped using specific monoclonal antibodies in an ELISA test. The majority of the samples (26 out of 38) were found to exhibit Subgroup I antigenicity. Only two specimens, collected from the same herd in two consecutive months, were found to belong to Subgroup II. To characterize further the circulating rotaviruses, electrophoretic analysis of the RNA genome was performed on samples selected from nine different herds. Great variability in the RNA electropherotypes was observed. No correlation was found between subgroup specificity and the migration of the two smaller segments (Genes 10 and 11), as has been described for human rotaviruses.

    1992-06-01

    Ultramafic-hosted deposits of magnesite (MgCO3) have been studied on Margarita Island, Venezuela, to elucidate the source of carbon and conditions of formation for this type of ore. Petrographic, mineralogic, and δ18O data indicate that magnesite precipitated on Margarita in near-surface environments at low P and T. δ13C ranges from -9 to -16‰ PDB within the magnesite and -8 to -10‰ PDB within some calcite and dolomite elsewhere on the island. The isotopically light dolomite fills karst and the calcite occurs as stock-work veins which resemble the magnesite deposits. These carbon isotopic ratios are consistent with a deep-seated source rather than an overlying source from a zone of surficial weathering. However, there is not much enrichment of precious metals and no enrichment of heavy rare-earth elements, as would be expected if the carbon had migrated upward as aqueous carbonate ions. The carbon probably has risen as a gaseous mixture of CO2 and CH4 which partially dissolved in near-surface water before leaching cations and precipitating as magnesite and other carbonates. The process probably is ongoing, given regional exhalation of carbonaceous gases.

    Dengue is a mosquito-borne viral disease that has evolved from a sporadic infection to a major public health problem in the Americas, Southeast Asia and the western Pacific, and Africa. Its incidence has increased 30-fold over the past 50 years, and although the true disease burden is not well known, the annual incidence in some areas of the Americas may reach 5%-10% of all children when underreporting is considered. We recently analyzed the disease burden of dengue in Venezuela, and we found an overall decline in case numbers and mortality over the period of 1950-2011. However, there were increases in case number and mortality during epidemic years, especially among children. In this report, we focus on the most recent period of data, from 2000 to 2011, comparing pediatric and adult case numbers and mortality. © The Author 2015.

    Well log-seismic sequence stratigraphy analysis in the Eastern Venezuela Foreland Basin leads to study of the evolution of sedimentary sequences onto the Cretaceous-Paleocene passive margin. This basin comprises two different foredeep sub-basins: The Guarico subbasin to the west, older, and the Maturin sub-basin to the east, younger. A foredeep switching between these two sub-basins is observed at 12.5 m.y. Seismic interpretation and well log sections across the study area show sedimentary sequences with transgressive sands and coastal onlaps to the east-southeast for the Guarico sub-basin, as well as truncations below the switching sequence (12.5 m.y.), and the Maturin sub-basin shows apparent coastal onlaps to the west-northwest, as well as a marine onlap (deeper water) in the west, where it starts to establish. Sequence stratigraphy analysis of these sequences with well logs allowed the study of the evolution of stratigraphic section from Paleocene to middle Miocene (68.0-12.0 m.y.). On the basis of well log patterns, the sequences were divided in regressive-transgressive-regressive sedimentary cycles caused by changes in relative sea level. Facies distributions were analyzed and the sequences were divided into simple sequences or sub- sequences of a greater frequencies than third order depositional sequences.

    Full Text Available For a long time, the Venezuelan democracy was an exception in South America due to a party system that was based on what was known as the ‘Punto Fijo Pact’. At the start of the 1980s a series of economic, social and political events began to occur, which caused this ‘exceptionalism’ to stagger and disrupt the institutionality of the traditional Venezuelan democratic State. The events led to a deep national crisis and the birth of a new political era. By the end of the 1990s, there had been a significant shift towards left-wing governance. Hugo Chávez Frías subsequently won the presidential elections in 1998. This paper analyzes some aspects of the criminal policies that were implemented during the reign of left-wing leader Chávez till his death in 2013 and thereafter by Chavist party president elect, Nicolás Maduro during 2013-2014. Four stages can be identified in the behavior of incarceration rates. The first stage, from 1999 to 2000, was characterized by the lowest recordings of incarceration rates and the lowest measured percentage of preventive detention in Venezuela in thirty years. The second stage, from 2001 to 2005, saw a slight increase in the incarceration rate which then remained stable. The third stage, from 2006 to 2012, and the fourth stage, from 2013 to 2014, are characterized by sustained increases in preventive detention, incarceration and murder rates.

    During the 1940s and 1950s Venezuela was an important destination for migrants from Southern Europe, a flow that disappeared almost entirely during the 1960s, to be replaced by border movements and the largely illegal migration of Colombians. The oil boom of the 1970s saw an increase of the latter, which may have subsided during the 1980s due to the more difficult economic conditions that have also led to significant emigration levels of Venezuelans and former immigrants. Methods of data collection systems that provide information on migrants include the National Population and Housing Census, the National Household Survey, migration surveys, arrival and departure statistics, registration systems operated by the Direccion General Sectorial de identificacion y Control de Extranjeros, the 1980 regularization drive, statistics gathered by the Ministry of Labor, and vital and civil registration statistics. The lack of effective coordination among the different government agencies gathering information and the administrative nature of the data collected give rise to problems of comparability. Mechanisms to publish and disseminate the data available are not well developed, so that researchers often have no access to potentially useful sources of information. Problems of timeliness in the publication of the most widely used information are also present, as is the large gap existing in data pertaining to emigration, be it of Venezuelan nationals or of immigrants leaving the country.

    2008-01-01

    This paper is about the wood anatomy of 31 species, belonging to 17 genera, of the Mimosoideae subfamily (Leguminosae), proceeding from different geographical regions of Venezuela. For each species, one to five individuals were studied. The descriptions were realized according to the IAWA Committee(1989). The studied species may be divided in two groups according to the presence or absence of septate fibers. All species of Inga showed septate fibers, whereas Albizia and Enterolobium included species with septate fibers and also species with non-septate fibers. The quantitative characteristics of the vessels and the width of rays showed sufficient variation as to be considered important characteristics from ataxonomic point of view. The most common parenchyma type was vasicetric, aliform and confluent. In Calliandra laxa, Prosopis juliflora and Zygia longifolia the main parenchyma type was in wide bands; whereas in Cedrelinga cateniformis, the main parenchyma type was thin vasicentric. All species studied, with the exception of Cedrelinga cateniformis, presented prismatic crystals in the parenchymatous axials cells. In spite of finding certain anatomical uniformity, it was possible to elaborate a key for the identification of the studied species.

    Increases in oil recovery factors through enhanced oil recovery (EOR) technologies has become an important issue in the petroleum industry because of depleting reserves of conventional fossil fuels and the low low mobility of extra heavy oils. Methodologies with different approaches have been developed to define the most suitable technology in specific reservoirs. The purpose of this paper was to determine which EOR technologies were the most appropriate for the entire Urdaneta reservoir in Venezuela, and to determine where the technologies could be applied in terms of reservoir volume. Specifically, the paper described the discretized screening methodology and showed an example of its application in the Urdaneta field. The processing of the static model of this field was described, since this is an input requirement for the EOR screening methodology. Screening results were also analysed and shown as color codes maps. The EOR screening methodology demonstrates that it is possible to evaluate the reservoir using very detailed input information. 4 refs., 3 tabs., 10 figs.

    2006-01-01

    Throughout the 1990s, all Latin American countries but Cuba implemented health care sector reforms based on a neoliberal paradigm that redefined health care less as a social right and more as a market commodity. These reforms were couched in the broader structural adjustment of Latin American welfare states as prescribed by international financial institutions since the mid-1980s. However, since 2003, Venezuela has been developing an alternative to this neoliberal trend through its health care reform program, Misión Barrio Adentro (Inside the Neighborhood). In this article, the authors review the main features of the Venezuelan health care reform, analyzing, within their broader sociopolitical and economic contexts, previous neoliberal health care reforms that mainly benefited transnational capital and domestic Latin American elites. They explain the emergence of the new health care program, Misión Barrio Adentro, examining its historical, social, and political underpinnings and the central role played by popular resistance to neoliberalism. This program not only provides a compelling model of health care reform for other low- to middle-income countries but also offers policy lessons to wealthy countries.

Trata-se de uma técnica de análise 3D não invasiva atualmente utilizada no setor mineral para caracterização de carvão, minerais industriais e de base, além de metais preciosos, complementando técnicas de microscopia já existentes como MLA e QEMSCAN. A técnica já é empregada há algum tempo na indústria do petróleo para a caracterização de tamanho e distribuição de poros, permitindo simular o fluxo de óleo em rochas reservatório. Além disso, a caracterização de poros em 3D permite a simulação de fluxo em processos de lixiviação. Requerendo pouca ou nenhuma preparação da amostra, comparativamente às técnicas de microscopia bi ou unidimensionais proporciona vantagens como a preparação muito mais ágil da amostra, aquisição direta de dados volumétricos, análise quantitativa em 3D e menor tempo de análise aliado a maior representatividade do material analisado. Particularmente em estudos de metais preciosos, tem-se um significativo aumento na probabilidade de detecção dos minerais de interesse. Recentes avanços com o emprego de dupla magnificação – projeção cônica aliada à utilização de lentes ópticas - possibilitam a aquisição de imagens com resolução submicrométrica com sensível melhoria no contraste entre as fases.

Larval bioassays were conducted on samples collected in 2008 and 2010, and the levels of α- and β-esterases, mixed-function oxidases, glutathione-S-transferase and insensitive acethyl cholinesterase were determined. Larval populations from western Venezuela obtained during 2008 and 2010 were found to be susceptible to temephos, with low resistance ratios and without overexpression of enzymes. The low RR values reveal the effectiveness of temephos in controlling the larval populations of Ae. aegypti. Control strategies must be vigorously monitored to maintain the susceptibility to temephos of these populations of Ae. aegypti. © 2013 Society of Chemical Industry.

    Full Text Available This work reports the second record of the scorpion Tityus bahiensis Perty from Venezuela. The specimen was found alive in a wardrobe at a hotel resort in Margarita Island, northeastern Venezuela. Morphological characterization allowed its assignment to the Tityus bahiensis population inhabiting the southernmost area of the species' geographic range, e.g. the state of São Paulo in Brazil, northern Argentina and Paraguay. The fact that the only available Venezuelan antiscorpion (anti-Tityus discrepans serum does not neutralize the effects of alpha- and beta-toxin from Tityus serrulatus venom (which resembles in composition that of T. bahiensis constitutes a warning to local clinicians confronted with envenomations by noxious species transported to Venezuela from Brazil by human agency.

  1. International Uranium Resources Evaluation Project (IUREP) orientation phase mission summary report: Venezuela

    International Nuclear Information System (INIS)

    1985-01-01

    A report has recently been published which describes the findings of the International Uranium Resources Evaluation Project (IUREP) mission to Venezuela. The IUREP Orientation Phase mission to Venezuela estimates that the Speculative Resources of that country fall within the range 2,000 to 42,000 tonnes uranium.- The majority of this potential is expected to be located in the Precambrian crystalline and sedimentary rocks of the Guayana Shield. Other potentially favorable geologic environments include Cretaceous phosphorite beds, continental sandstone and granitic rocks. The mission recommends that approximately US $18 million be spent on exploration in Venezuela over the next five years. The majority of this expenditure would be for surface surveys utilizing geologic studies, radiometric and geochemical surveys and some drilling for geologic information. Additional drilling would be required later to substantiate preliminary findings. (author)

    Wild plants of the family Convolvulaceae are hosts for a few New World begomoviruses (genus Begomovirus, family Geminiviridae). In this work, we report the complete genome sequence of a new begomovirus infecting the wild convolvulaceous plant Jacquemontia tamnifolia in Venezuela. The cloned bipartite genome showed the organization of typical New World begomoviruses and was found to be phylogenetically related to those of begomoviruses from Venezuela and other Caribbean countries. Several recombination events have been shown to have occurred involving genome fragment exchange with related begomoviruses infecting crops such as tomato and cucurbits and wild plants, including Jacquemontia sp. We propose the name jacquemontia yellow vein virus (JacYVV) for this new begomovirus.

    To compare internal migration and temperature as factors behind the decreasing trend in malaria deaths observed in Venezuela from 1905 to 1945, linear autoregressive models are fitted to a historical dataset. The model that only incorporates internal migration is the one with the best fit. The decreasing trend in malaria deaths in Venezuela, from 1905 to 1945, is not explained by a trend in mean annual temperature, but it is associated with an increase in the proportion of population in the Capital District, during a time period when the area was the principal attractor of migrations within the country.

O objetivo deste trabalho é apresentar alguns aspectos do processo de deslocamentos transfronteiriços no norte do Brasil, no município de Pacaraima (Estado de Roraima e na fronteira sul da Venezuela, no município de Gran Sabana (Estado Bolívar, e, ao mesmo tempo, apontar as tendências e reflexos nas configurações socioculturais nessas zonas de contato. Nessa fronteira Brasil-Venezuela, podemos afirmar que o trânsito maior é de brasileiros para a Venezuela e para a Guiana, em decorrência das possibilidades de atuarem nas atividades de mineração, no comércio local e no setor de transportes, além das atividades ilegais, como tráfico de mulheres, contrabando de combustível e câmbio ilegal de moeda. Apresenta-se, no entanto, uma nova tendência que é a imigração de estrangeiros de outros países do continente, tais como peruanos e colombianos. Esses migrantes transfronteiriços percorrem os países fronteiriços em itinerários cuja porta de entrada é a Venezuela e a Guiana, mas também o Estado do Amazonas.BORDER zones are zones of cultural lending, borrowing and appropriation, and, therefore, a privileged vantage point for understanding the phenomenon of international migration.

    Abreu Olivo, E A; Ablan de Flórez, E

    1994-12-01

    The authors carry out a research focused on the quantification and analysis of the main changes in feeding and nutrition in Venezuela between 1970 and 1992. Such research started with the review and adjustment of the Food Balance Sheets (Hojas de Balance de Alimentos) elaborated by the Instituto Nacional de Nutrición (National Nutrition Institute) between 1970 and 1979 in order to homogenize them in a methodological way to make them similar to those elaborated by that institution and the Fundación Polar for the 1980-90 period. Estimates were made about the daily and per person availability of food for human consumption (DCH) for 1991 and 1992. This report, a partial product of that research, characterizes the evolution of the lipidic DCH in Venezuela for the 1970-1992 period. This period has been divided in seven stages of the evolution of the total energetic DCH, as this reflects well the course of the daily and per person Food Purchasing Power (PCA); there is a direct and strong functional relationship between these two variables. Along those stages the behaviour of the lipidic DCH is studied and we try to view possible relationships between the evolution of the Venezeluans economical situation and the absolute and relative variations observed in the level and the structure of the lipidic DCH. This structure is analyzed from several points of view: groups of food sources, origin, "visibility", and place of origin. One purpose is to determine also which food groups are mainly responsible for the venezuelan's external lipidic dependence. A general picture of the evolution of the DCH for saturated fatty acids and cholesterol is made, as well as of the variations experienced by the P/S and M/S relationships. It was found that the most dynamic elements, those that can explain a very high percentage of the variations observed in the level and the structure of the lipidic DCH were: the groups of foods of Visible Fats, Milk and dairy products, and Meats; vegetal lipids

  13. STSHV a teleinformatic system for historic seismology in Venezuela

    Choy, J. E.; Palme, C.; Altez, R.; Aranguren, R.; Guada, C.; Silva, J.

    2013-05-01

    From 1997 on, when the first "Jornadas Venezolanas de Sismicidad Historica" took place, a big interest awoke in Venezuela to organize the available information related to historic earthquakes. At that moment only existed one published historic earthquake catalogue, that from Centeno Grau published the first time in 1949. That catalogue had no references about the sources of information. Other catalogues existed but they were internal reports for the petroleum companies and therefore difficult to access. In 2000 Grases et al reedited the Centeno-Grau catalogue, it ended up in a new, very complete catalogue with all the sources well referenced and updated. The next step to organize historic seismicity data was, from 2004 to 2008, the creation of the STSHV (Sistema de teleinformacion de Sismologia Historica Venezolana, http://sismicidad.hacer.ula.ve ). The idea was to bring together all information about destructive historic earthquakes in Venezuela in one place in the internet so it could be accessed easily by a widespread public. There are two ways to access the system. The first one, selecting an earthquake or a list of earthquakes, and the second one, selecting an information source or a list of sources. For each earthquake there is a summary of general information and additional materials: a list with the source parameters published by different authors, a list with intensities assessed by different authors, a list of information sources, a short text summarizing the historic situation at the time of the earthquake and a list of pictures if available. There are searching facilities for the seismic events and dynamic maps can be created. The information sources are classified in: books, handwritten documents, transcription of handwritten documents, documents published in books, journals and congress memories, newspapers, seismologic catalogues and electronic sources. There are facilities to find specific documents or lists of documents with common characteristics

    Full Text Available Se realizó un estudio epidemiológico descriptivo de corte transversal, con el objetivo de determinar la morbilidad oculta por parasitismo intestinal en Lagunita, municipio Girardot, Venezuela; en el período de enero a octubre de 2009. El universo fue de 286 niños, lo que se corresponde con la población total del grupo de edad de menores de 15 años. De estos se seleccionaron por muestreo aleatorio simple 43 pacientes, a los que se les aplicó un cuestionario y se confeccionó una guía de observación, para describir los factores epidemiológicos que influyen en la infestación por parasitismo intestinal. Además, se les realizaron análisis de las heces fecales seriadas para el diagnóstico del parasitismo. El método estadístico fue el cálculo de las frecuencias absolutas y relativas. A través del estudio de las heces fecales seriadas se obtuvo que 27 pacientes tenían parasitosis intestinal, para una morbilidad de 62,79%, con una mayor incidencia en los niños de cinco a nueve años de edad. El sexo femenino fue el más afectado. Los factores epidemiológicos que más influyeron fueron: los malos hábitos higiénicos personales, el entorno desfavorable y el consumo de agua no potable; existió relación entre el nivel socioeconómico, los factores epidemiológicos y la morbilidad por parasitismo intestinal. Predominó la parasitosis por Entamoeba Histolytica, con 11 casos, para un 40,74%. La diarrea, las molestias abdominales y la pérdida de apetito constituyeron los principales síntomas

    Full Text Available Para evaluar el efecto del enriquecimiento con nutrientes sobre la comunidad del fitoplancton del embalse La Mariposa (Venezuela, se establecieron microcosmos "in situ" durante 6 días. Los microcosmos consistieron en bolsas de polietileno con 10 l de agua epilimnética filtrada del embalse, sometidos a diferentes combinaciones de enriquecimiento con fósforo y nitrógeno, para así simular un proceso de eutroficación. Se determinaron las concentraciones de clorofila 'a', la concentración de nitrógeno total y fósforo total y la proporción numérica de los diferentes grupos del fitoplancton. Como consecuencia del enriquecimiento de nutrientes, se produjo un aumento en la biomasa del fitoplancton, siendo las respuestas más pronunciadas en los tratamientos donde ambos nutrientes estaban presentes. Los grupos Cryptophyta, Euglenophyta y Pyrrophyta desaparecieron de los microcosmos fertilizados al finalizar el período de estudio, mientras que las Chlorophyta y las Cyanobacteria aumentaron sus proporciones relativas. Las diatomeas disminuyeron su proporción relativa a altas concentraciones de nitrógeno. Aunque la técnica del microcosmos tiene limitaciones en su significado ecológico, permite obtener una valiosa aproximación para entender lo que ocurre en las situaciones naturales.The effect of nutrient enrichment (N and P on the phytoplankton community of La Mariposa reservoir (Venezuela was studied. Polyethylene bags (microcosms were filled with 10 l of filtered epilimnetic water of the reservoir, and enriched with different nutrient proportions, simulating an eutrophication process. Chlorophyll 'a', total nitrogen, total phosphorus, and phytoplankton abundance were determined. There was an increase in phytoplankton abundance because of nutrient enrichment, specially when both nutrients were present. After the experiments, Cryptophyta, Euglenophyta, and Pyrrophyta dissappeared from the microcosms, whereas Chlorophyta and Cyanobacteria

    2014-03-01

    Full Text Available The genus Eulophia embraces over 230 species distributed through the tropical and subtropical Africa, Asia, Australia and the Americas. In Neotropics it is represented by a sole species – E. alta. The aim of the presented study was to evaluate the difference between ecological niches occupied by American and African populations of this species based on the ecological niche modeling. The similarity between the glacial and present niches occupied by E. alta was calculated and the factors limiting the species occurrence were identified. Areas of seasonal tropical forest, tropical savanna and woodland served as refugia for the studied species during last glacial maximum and they were more widespread in Neotropics than in Africa. No significant niche shift after last glacial maximum was observed. The distribution of E. alta in its whole range is restricted mainly by temperature seasonality. The differences in the niches occupied by African and Neotropical populations of E. alta suggest preglacial disjunction of the species range and independent adaptation of both groups. Despite the significant range disjunction of E. alta the species is characterized by relatively high degree of niche conservatism.

    Full Text Available El bienestar psicológico en las personas de alta capacidad intelectual ha sido motivo de controversia en la literatura especializada. En ocasiones se ha considerado que estas personas son más proclives a un desajuste psicológico, mientras que otras veces los resultados han sido poco concluyentes. En el presente trabajo se ha estudiado el bienestar psicológico en personas de altas capacidades intelectuales, administrando la Escala de Bienestar Psicológico a 28 participantes de edades comprendidas entre los 22 y 34 años de edad. Fueron divididos en 2 grupos, uno de altas capacidades y otro de inteligencia estándar. El grupo de altas capacidades había sido identificado como tal 25 años atrás, cuando tenían una edad comprendida entre los 5 y 13 años, utilizando el modelo de los 3 anillos de Renzulli. Los resultados indicaron la inexistencia de diferencias significativas entre los participantes de altas capacidades e inteligencia estándar en las diferentes subescalas de bienestar personal, a excepción de la subescala de bienestar material.

    The red palm mite (RPM), Raoiella indica Hirst (Acari: Tenuipalpidae), is an invasive pest in the New World, where it is currently considered a serious threat to coconut and banana crops. It was first reported from northern Venezuela in 2007. To determine its current distribution in this country, surveys were carried out from October 2008 to April 2010 on coconut (Cocos nucifera L.), banana (Musa spp.), ornamental plants and weeds in northern Venezuela. Higher population levels of RPM were registered on commercial coconut farms in Falcón and Sucre states but also on other plant species naturally growing along the coastal line in Anzoategui, Aragua, Carabobo, Monagas and Nueva Esparta states. Out of 34 botanical species evaluated, all RPM stages were observed only on eight arecaceous, one musaceous and one streliziaceous species, indicating that the pest developed and reproduced only on these plants. Mite specimens found on weeds were considered spurious events, as immature stages of the pest were never found on these. Amblyseius largoensis (Muma) (Acari: Phytoseiidae) was the most frequent predatory mite associated with RPM in all sampling sites. The results indicate that RPM has spread to extensive areas of northern Venezuela since its initial detection in Güiria, Sucre state. Considering the report of this pest mite in northern Brazil in the late 2009, additional samplings in southern Venezuela should be carried out, to evaluate the possible presence of RPM also in that region.

    Full Text Available Este artículo explora la conformación del mito de la democracia racial en Venezuela, a través del análisis de la novela nacional Doña Bárbara de Rómulo Gallegos. Publicada por primera vez en 1929, la novela representa una de las obras fundantes tanto del mito de la democracia racial, como de las disposiciones contemporáneas de la identidad nacional en Venezuela. El análisis desarrollado en el trabajo, relaciona la función proyectiva de los diseños nacionales de la élite criolla, con la reconfiguración y consolidación de la colonialidad del poder en la Venezuela del siglo XX. Asimismo, se examinan las prácticas representacionales, contenidas en la obra, y las tecnologías civilizatorias que se proponen allí como solución al problema de la «barbarie» de la sociedad y la naturaleza en Venezuela.

    Streptomyces venezuelae is a promising chassis in synthetic biology for fine chemical and secondary metabolite pathway engineering. The potential of S. venezuelae could be further realized by expanding its capability with the introduction of its own in vitro transcription-translation (TX-TL) system. TX-TL is a fast and expanding technology for bottom-up design of complex gene expression tools, biosensors and protein manufacturing. Herein, we introduce a S. venezuelae TX-TL platform by reporting a streamlined protocol for cell-extract preparation, demonstrating high-yield synthesis of a codon-optimized sfGFP reporter and the prototyping of a synthetic tetracycline-inducible promoter in S. venezuelae TX-TL based on the tetO-TetR repressor system. The aim of this system is to provide a host for the homologous production of exotic enzymes from Actinobacteria secondary metabolism in vitro. As an example, the authors demonstrate the soluble synthesis of a selection of enzymes (12-70 kDa) from the Streptomyces rimosus oxytetracycline pathway. © 2017 The Authors.

  8. Holocene evolution of the western Orinoco Delta, Venezuela

    2003-01-01

    The pristine nature of the Orinoco Delta of eastern Venezuela provides unique opportunities to study the geologic processes and environments of a major tropical delta. Remote-sensing images, shallow cores, and radiocarbon-dating of organic remains form the basis for describing deltaic environments and interpreting the Holocene history of the delta. The Orinoco Delta can be subdivided into two major sectors. The southeast sector is dominated by the Rio Grande-the principal distributary-and complex networks of anastomosing fluvial and tidal channels. The abundance of siliciclastic deposits suggests that fluvial processes such as over-bank flooding strongly influence this part of the delta. In contrast, the northwest sector is represented by few major distributaries, and overbank sedimentation is less widespread relative to the southeast sector. Peat is abundant and occurs in herbaceous and forested swamps that are individually up to 200 km2 in area. Northwest-directed littoral currents transport large volumes of suspended sediment and produce prominent mudcapes along the northwest coast. Mapping of surface sediments, vegetation, and major landforms identified four principal geomorphic systems within the western delta plain: (1) distributary channels, (2) interdistributary flood basins, (3) fluvial-marine transitional environments, and (4) marine-influenced coastal environments. Coring and radiocarbon dating of deltaic deposits show that the northern delta shoreline has prograded 20-30 km during the late Holocene sea-level highstand. Progradation has been accomplished by a combination of distributary avulsion and mudcape progradation. This style of deltaic progradation differs markedly from other deltas such as the Mississippi where distributary avulsion leads to coastal land loss, rather than shoreline progradation. The key difference is that the Orinoco Delta coastal zone receives prodigious amounts of sediment from northwest-moving littoral currents that transport

El propósito de la descentralización es aumentar la capacidad de respuesta eficiente del sistema de servicios a los problemas de salud a la población entre los diferentes niveles de poder central, estadal y municipal, así como brindarle una mayor participación a las comunidades en su solución. En Venezuela las instituciones que prestan servicios de salud son numerosas, en su mayoría independientes y ausentes de una coordinación efectiva por parte del Ministerio de Sanidad y Asistencia Social (MSAS, ente creado en 1936 con mayor injerencia en los asuntos relativos a la salud. El MSAS se orienta hacia una política de centralización normativa – procedimental y desconcentración programática que consiste en la transferencia de las funciones administrativas, requeridas para el desarrollo de los programas, a los órganos regionales del Sistema Nacional de Salud.

    Site effects have been recognized to play an important role in damage distribution of destructive earthquakes. These effects have been observed in Venezuela especially during the 1967 Caracas earthquake, when 4 buildings with 10 and more storeys during the Caracas 1967 earthquake collapsed, and a big number of them in the same deep sediment area have been seriously damaged. This motivated the development of studies regarding the subsurface configuration of Caracas and Barquisimeto during the last decade, with a seismic microzoning project realized in both cities from 2005 to 2009. The main results of this project were the development of design response spectra for the different microzones within the sedimentary basin, as well as estimates of landslide hazard. Implementation of the results in municipality ordinances is actually discussed with local authorities. They are aimed to address mitigation for new constructions by the application of the specific design spectra, for existing buildings via evaluation and retrofitting strategies, and for slope areas (informal, as well as formal developments) due to the identification of areas that may not be developed or require detailed studies of slope stabilities. Since then, seismic microzoning studies were started in Cumaná, Guarenas/Guatire and Lara state, and within a broader context of integrated risk management, which includes flooding, landslide and technological risks, in Mérida, Valencia, Maracay, Barcelona/Puerto La Cruz and Valle de la Pascua. The projects are coordinated by the Venezuelan Foundation for Seismological Research (FUNVISIS) in cooperation with local universities. Efforts are done to unable local researchers to apply the methodologies in other cities as Valera, Trujillo, Boconó, San Cristóbal and Tucacas. A unified seismic hazard map as input motion to these studies is actually in development. Depending on the local characteristics, building inventory and vulnerability analysis are done for risk

    Sucre municipality is a large, densely populated marginal area in the eastern part of Caracas, Venezuela that consistently has more cases of tuberculosis than other municipalities in the country. To identify the neighborhoods in the municipality with the highest prevalence of tuberculosis, and determine whether the Mycobacterium tuberculosis strain distribution in this municipality is different from that previously found in the western part of Caracas and the rest of Venezuela, we collected data on all tuberculosis cases in the municipality diagnosed in 2005-6. We performed two separate molecular epidemiological studies, spoligotyping 44 strains in a first study, and spoligotyping 131 strains, followed by MIRU-VNTR 15 on 21 clustered isolates in the second. With spoligotyping, the most common patterns were Shared International Type SIT17 (21%); SIT42 (15%); SIT93 (11%); SIT20 (7%); SIT53 (6%), a distribution similar to other parts of Venezuela, except that SIT42 and SIT20 were more common. MIRU-VNTR 15 showed that six of seven SIT17 strains examined belonged to a large cluster previously found circulating in Venezuela, but all of the SIT42 strains were related to a cluster centered in the neighborhoods of Unión and Maca, with a MIRU-VNTR pattern not previously seen in Venezuela. It appears that a large percentage of the tuberculosis in the Sucre municipality is caused by the active transmission of two strain families centered within distinct neighborhoods, one reflecting communication with the rest of the country, and the other suggesting the insular, isolated nature of some sectors.

    In 1984 the Venezuelan Work Groups in Mycology (VWGM) were created introducing an innovative approach to the study of the mycoses in Venezuela. To study the occurrence of the mycoses in Venezuela. Review the reported cases of mycoses by the newsletter Boletín Informativo Las Micosis en Venezuela (VWGM) from 1984 to 2010. The data collected showed 36,968 reported cases of superficial mycoses, 1,989 of deep systemic cases, and 822 of localized mycoses. Pityriasis dermatophytosis was the most common superficial infection, and paracoccidioidomycosis and histoplasmosis the most frequent deep systemic infection. Chromoblastomycosis was the most frequently diagnosed subcutaneous infection. The data provided showed the distribution by geographical area for each of the fungal infections studied, which may help to establish the endemic areas. Superficial mycosis is a public health problem due to its high morbidity and is probably responsible for some of the outbreaks in high-risk groups. Paracoccidioidomycosis and histoplasmosis were reported more often, which agrees with earlier reports prior to the formation of the VWGM. Cases of sporotrichosis and chromoblastomycosis in Venezuela can be considered unique due to the high number of cases. This study highlights the contribution of the VWGM to the behavior of the mycoses in Venezuela, its incidence, prevalence, and the recognition of these infections as a problem of public health importance. The VWGM should keep working in this endeavor, not only reporting new cases, but also unifying the clinical and epidemiological criteria, in order to properly monitor the evolving epidemiological changes reported in these types of infections.

    2008-04-30

    This report describes computational fluid dynamics (CFD) modeling and pilot-scale testing conducted to demonstrate the ability of the Advanced Layered Technology Approach (ALTA) to reduce NO{sub x} emissions in a pulverized coal (PC) boiler. Testing specifically focused on characterizing NO{sub x} behavior with deep burner staging combined with Rich Reagent Injection (RRI). Tests were performed in a 4 MBtu/hr pilot-scale furnace at the University of Utah. Reaction Engineering International (REI) led the project team which included the University of Utah and Combustion Components Associates (CCA). Deep burner staging and RRI, combined with selective non-catalytic reduction (SNCR), make up the Advanced Layered Technology Approach (ALTA) for NO{sub x} reduction. The application of ALTA in a PC environment requires homogenization and rapid reaction of post-burner combustion gases and has not been successfully demonstrated in the past. Operation of the existing low-NO{sub x} burner and design and operation of an application specific ALTA burner was guided by CFD modeling conducted by REI. Parametric pilot-scale testing proved the chemistry of RRI in a PC environment with a NOx reduction of 79% at long residence times and high baseline NOx rate. At representative particle residence times, typical operation of the dual-register low-NO{sub x} burner provided an environment that was unsuitable for NO{sub x} reduction by RRI, showing no NOx reduction. With RRI, the ALTA burner was able to produce NO{sub x} emissions 20% lower than the low-NO{sub x} burner, 76 ppmv vs. 94 ppmv, at a burner stoichiometric ratio (BSR) of 0.7 and a normalized stoichiometric ratio (NSR) of 2.0. CFD modeling was used to investigate the application of RRI for NO{sub x} control on a 180 MW{sub e} wall-fired, PC boiler. A NO{sub x} reduction of 37% from baseline (normal operation) was predicted using ALTA burners with RRI to produce a NO{sub x} emission rate of 0.185 lb/MBtu at the horizontal nose of

O modelo de estimativa da doença utilizado foi o desenvolvido por Hyre (1954, o qual requer dados diários de chuva e temperatura. Esses dados foram obtidos de 106 estações meteorológicas, situadas nos estados de Mérida, Táchira e Trujillo, para períodos de 31 anos. O modelo de Hyre foi aplicado para todas as estações, obtendo-se as seguintes variáveis: número de dias favoráveis à doença (DFD; número de períodos com dez dias favoráveis consecutivos, denominado de ocorrência (O; e número de pulverizações requeridas para o controle da doença (S. Essas variáveis foram utilizadas para calcular o Índice de Máximo Risco (MRI e o Índice de Risco Provável (PRI. A interpolação desses índices foi usada para gerar mapas de risco climático para cada época de semeadura. Os mapas de MRI e PRI mostraram que os maiores riscos para a proliferação da requeima da batata ocorre na estação chuvosa, de maio a julho, decrescendo durante as estações seca e de transição. Entretanto, alta variabilidade do risco para a doença foi observada em todas as épocas de semeadura. Os mapas gerados pela combinação do modelo agrometeorológico de previsão da doença e GIS também mostraram que em boa parte das áreas produtoras de batata na região andina da Venezuela a redução do número de pulverizações pode ser possível, no entanto há necessidade de novas pesquisas para se comprovar isso.

Todas las especies fueron hermafroditas. K. daigremontiana y K. pinnata resultaron xenógamas obligadas; mientras S. coccinea, N. glauca y E. mitis resultaron parcialmente autocompatibles no autógamas. Las cinco especies mostraron una alta a-signación de biomasa total con respecto a otros sistemas de polinización. La a-signación de biomasa reproductiva fue siempre menor a las asignaciones de biomasa de atracción y de biomasa vegetativa floral. La asignación de biomasa masculina fue mayor que la femenina para N. glauca, S. coccinea y E. mitis, y menor para K. daigremontiana y K. pinnata. Las especies introducidas no parecen afectar notoriamente las eficiencias reproductivas de las especies nativas. Las eficiencias reproductivas de las especies nativas fueron superiores a las de las especies introducidas. Las eficiencias reproductivas de las especies introducidas resultaron bajas, debido a que se encuentran afectadas por la ausencia de sus polinizadores naturales.The floral biology, the pollination biology and the mating system were studied in two native and three introduced species of an arboretum in

    Full Text Available Los sistemas reproductivos fueron evaluados para 51 especies de plantas en relación a la forma de vida, sistema de polinización, tipo de vegetación y fenología de floración en la planicie costera de la península de Paraguaná, Venezuela. Los sistemas sexuales resultaron independientes de la forma de vida, sistema de polinización, tipo de vegetación y fenología. La distribución de frecuencia de los sistemas sexuales fue 82.3% hermafroditas, 15.6% monoicas y 1.9% dioicas. Todos los sistemas sexuales mostraron un pico de floración durante el mínimo de precipitación. La frecuencia de los sistemas genéticos de reproducción fue 35.3% de especies autoincompatibles y 64.7% de especies autocompatibles, incluyendo especies parcialmente autocompatibles. Entre las especies autocompatibles, 45.1% resultaron autogamas y 19.6% no autogamas. Los sistemas genéticos de reproducción estaban asociados significativamente a: (1 forma de vida de las plantas, especies autocompatibles tienden a ser especies herbáceas y especies autoincompatibles tienden a ser árboles y arbustos; (2 tipo de vegetación, en los tres tipos de vegetación predominan las especies autocompatibles, pero en la vegetación de manglar la proporción de especies autocompatibles y autoincompatibles fue similar; y (3 sistema de polinización, muchas de las especies autocompatibles tenían sistemas de polinización polifílicos. Los sistemas de apareamiento, xenogamia y autogamia, solo estaban asociados significativamente con la forma de vida de las plantas. La xenogamia predominó para especies leñosas, mientras que la autogamia predominó en especies herbáceas. La alta frecuencia de hermafroditismo, autocompatibilidad genética y autogamia son relacionados con la abundancia de especies herbáceas en las áreas de estudio, la polinización polifílica y a las condiciones climáticas extremas unida a la insularidad de la península de Paraguaná.Breeding systems of the Paraguan

    Full Text Available Las esponjas son uno de los grupos de animales sésiles más abundantes y diversos de los fondos marinos tropicales, siendo un componente importante en los arrecifes coralinos, aunque poco estudiado a nivel de especies. El objetivo de este estudio fue caracterizar la comunidad de esponjas en el gradiente de profundidad de un arrecife coralino en Isla Larga, Parque Nacional San Esteban, Venezuela. Se trabajaron siete profundidades (1, 3, 6, 9, 12, 15 y 18m donde se midió la sedimentación neta y bruta, el índice de rugosidad, y se evaluó la riqueza, densidad y cobertura de las esponjas. Se identificaron 17 especies en 10 familias. La mayor densidad y cobertura se encontró a los 6m (6.03ind/m2, 11%, coincidiendo con la mínima sedimentación neta y la máxima rugosidad del sustrato. Las especies más abundantes fueron Desmapsamma anchorata, Amphimedon erina y Scopalina rueztleri. El análisis de componentes principales arrojó una separación de esta comunidad en 3 zonas, la somera (1 y 3m, donde las esponjas están sometidas a una tensión producida por el oleaje y alta iluminación, y las zonas media (6, 9 y 12m y profunda (15 y 18m, con características más favorables, dada una menor iluminación y sedimentación.

  10. Household energy use in urban Venezuela: Implications from surveys in Maracaibo, Valencia, Merida, and Barcelona-Puerto La Cruz

    Energy Technology Data Exchange (ETDEWEB)

    Figueroa, M.J.; Sathaye, J.

    1993-08-01

    This report identifies the most important results of a comparative analysis of household commercial energy use in Venezuelan urban cities. The use of modern fuels is widespread among all cities. Cooking consumes the largest share of urban household energy use. The survey documents no use of biomass and a negligible use of kerosene for cooking. LPG, natural gas, and kerosene are the main fuels available. LPG is the fuel choice of low-income households in all cities except Maracaibo, where 40% of all households use natural gas. Electricity consumption in Venezuela`s urban households is remarkably high compared with the levels used in households in comparable Latin American countries and in households of industrialized nations which confront harsher climatic conditions and, therefore, use electricity for water and space heating. The penetration of appliances in Venezuela`s urban households is very high. The appliances available on the market are inefficient, and there are inefficient patterns of energy use among the population. Climate conditions and the urban built form all play important roles in determining the high level of energy consumption in Venezuelan urban households. It is important to acknowledge the opportunities for introducing energy efficiency and conservation in Venezuela`s residential sector, particularly given current economic and financial constraints, which may hamper the future provision of energy services.

    2006-06-01

    Full Text Available This article analyzes the changes in violence in Venezuela during the last forty years. It links the ups and downs of the oil revenues and the political crisis of the country to the changes in the homicide rates, which increased from 7 per 100 thousand inhabitants in 1970 to 12 in 1990, 19 in 1998 and 50 in 2003. The article characterizes Venezuela as a rentist society and shows its trajectory from rural violence to the beginning of urban violence, the guerilla movements of the 60s, the delinquent violence related to the abundance of oil revenues and the violence during the popular revolt and the sackings of 1989 in Caracas. After this, we analyze the coups d'état of 1992 and the influence the political violence exerted upon criminal violence. We describe the political and party changes in the country, their influence upon the stabilization of homicide rates since the mid-90s and their remarkable increase during the H. Chávez government. The article finishes with an analysis of the current situation, the official prohibition to publish statistics on homicides and with some thoughts about the perspective of greater violence in Venezuela.O presente artigo analisa as mudanças na violência ocorridas na Venezuela nos últimos quarenta anos, relacionadas com os altos e baixos da renda petroleira e com a crise política no país, fatos que contribuíram para um aumento nas taxas de homicídios: de 7 por cada cem mil habitantes em 1970 a 12 em 1990, 19 em 1998 e 50 no ano de 2003. O artigo caracteriza a Venezuela como sociedade rentista e, a partir daí, faz uma retrospecção cobrindo desde a violência rural até os inícios da violência urbana, o movimento guerrilheiro dos anos sessenta, a criminalidade resultando da abundância dos recursos petroleiros e a violência em decorrência da revolta popular e dos saques ocorridos em 1989 em Caracas. Em seguida são analisados os golpes de Estado de 1992 e o impacto que a violência política exerceu

    Full Text Available O trabalho pretende analisar os circuitos e cenários das dinâmicas comerciais atuais da cidade alta de Salvador, a antiga zona comercial "nobre" que, após várias fases sucessivas de desenvolvimento nas últimas décadas, ainda hoje constitui a zona comercial mais densa da cidade. Em nível prático, nosso objetivo é caracterizar as dinâmicas: organização das empresas; características pessoais e profissionais dos comerciantes bem como suas percepções e opiniões. Em nível teórico, pretendemos discutir a validade das teorias dualistas das economias urbanas do terceiro mundo, através dos resultados empíricos deste caso específico de uma área total, a cidade alta, que engloba dentro de estruturas comerciais a priori modernas - shopping centers e tradicionais - as ruas comerciais. Enfim, para reforçar o caráter pragmático da pesquisa, nosso objetivo é refletir sobre as dificuldades e, por outro lado, as potencialidades da área. As análises mostram uma cidade alta bastante heterogênea em todos aspectos e internamente hierarquizada. Os shopping centers e a Avenida Sete de Setembro apresentam a maior intensidade das atividades e concentram as empresas de grande porte que servem de elo entre os espaços comerciais. Apesar desta semelhança estrutural entre os shopping centers e certos trechos do comércio de rua, os padrões locacionais e as estratégias das pequenas empresas assim como as características dos comerciantes traduzem uma dissociação dos espaços. A predominância das pequenas empresas e a heterogeneidade qualitativa dos estabelecimentos, os problemas de infra-estrutura de segurança e a falta de dinamismo dos comerciantes de rua destacam-se como as fraquezas da cidade alta. Por outro lado o resgate da história e o leque extremamente variado de atividade de áreas turísticas deverão constituir as bases para o desenvolvimento futuro da área.

    The emerging vector of Chagas disease, Triatoma maculata (Hemiptera, Reduviidae), is one of the most widely distributed Triatoma species in northern South America. Despite its increasing relevance as a vector, no consistent picture of the magnitude of genetic and phenetic diversity has yet been developed. Here, several populations of T. maculata from eleven Colombia and Venezuela localities were analyzed based on the morphometry of wings and the mitochondrial NADH dehydrogenase subunit 4 (ND4) gene sequences. Our results showed clear morphometric and genetic differences among Colombian and Venezuelan populations, indicating high intraspecific diversity. Inter-population divergence is suggested related to East Cordillera in Colombia. Analyses of other populations from Colombia, Venezuela, and Brazil from distinct eco-geographic regions are still needed to understand its systematics and phylogeography as well as its actual role as a vector of Chagas disease. © 2016 The Society for Vector Ecology.

    Lutzomyia evansi is a recognized vector of Leishmania infantum in Colombia and Venezuela. To describe and illustrate the morphological abnormalities in Lu. evansi females captured in a rural focus of visceral leishmaniasis in Trujillo, Venezuela. Phlebotomine sand flies were collected using CDC light traps, Shannon traps and aspiration in resting places. The identification was performed according to Young & Duncan (1994) and drawings were made using a microscope with camara lucida . Abnormalities in the cibarium of Lu. evansi were detected in 4 (0.12%) females of the 3,477 adults that were studied. Lutzomyia evansi can have uncommon morphological variants associated with an increase in the number of teeth in the cibarium and their arrangement, which may lead to errors in the taxonomic identification of anomalous specimens. The study of such deformities can serve to avoid taxonomic identification errors.

    An 83-year-old male patient is admitted to the central hospital in Cumana, Venezuela with severe urinary infection, history of hospitalizaions and prolonged antimicrobial treatments. A strain of Enterobacter cloacae was isolated showing resistance to multiple types of antibiotics (only sensitive to gentamicin), with phenotype of serine- and metallo-carbapenemases. Both, bla(VIM-2) and bla(KPC) genes were detected in the isolate. This is the first report of an Enterobacteriaceae species producing both KPC carbapenemase and VIM metallo carbapenemase in Venezuela. This finding has a great clinical and epidemiological impact in the region, because of the feasibility of transferring these genes, through mobile elements to other strains of Enterobacter and to other infection-causing species of bacteria.

    In 2010, an outbreak of febrile illness with arthralgic manifestations was detected at La Estación village, Portuguesa State, Venezuela. The etiologic agent was determined to be Mayaro virus (MAYV), a reemerging South American alphavirus. A total of 77 cases was reported and 19 were confirmed as seropositive. MAYV was isolated from acute-phase serum samples from 6 symptomatic patients. We sequenced 27 complete genomes representing the full spectrum of MAYV genetic diversity, which facilitated detection of a new genotype, designated N. Phylogenetic analysis of genomic sequences indicated that etiologic strains from Venezuela belong to genotype D. Results indicate that MAYV is highly conserved genetically, showing ≈17% nucleotide divergence across all 3 genotypes and 4% among genotype D strains in the most variable genes. Coalescent analyses suggested genotypes D and L diverged ≈150 years ago and genotype diverged N ≈250 years ago. This virus commonly infects persons residing near enzootic transmission foci because of anthropogenic incursions.

    Full Text Available This work reviews Venezuelan Bolivarianism and its relationship with the political discourses and projects during what has been called “Gran Venezuela” (Great Venezuela, 1974- 1983. During this period, Venezuela enjoyed a combination of two decades of democratic stability and high oil prices, becoming an exceptionally prosperous, free and peaceful country in Latin-America. In this context, democratic governments used political Bolivarian historicism in order to legitimize their apparent success as proof that they were complying with the vision set out by Simón Bolívar, traditionally associated with conservative thought and dictatorship. It also used Bolivarianism to project its status as an emerging power in the Third World.

    Streptomyces have a rich history as producers of important natural products and this genus of bacteria has recently garnered attention for its potential applications in the broader context of synthetic biology. However, the dearth of genetic tools available to control and monitor protein production precludes rapid and predictable metabolic engineering that is possible in hosts such as Escherichia coli or Saccharomyces cerevisiae. In an effort to improve genetic tools for Streptomyces venezuelae, we developed a suite of standardized, orthogonal integration vectors and an improved method to monitor protein production in this host. These tools were applied to characterize heterologous promoters and various attB chromosomal integration sites. A final study leveraged the characterized toolset to demonstrate its use in producing the biofuel precursor bisabolene using a chromosomally integrated expression system. In conclusion, these tools advance S. venezuelae to be a practical host for future metabolic engineering efforts.

    Limited information exists on the epidemiology of acute febrile respiratory illnesses in tropical South American countries such as Venezuela. The objective of the present study was to examine the epidemiology of influenza-like illness (ILI) in two hospitals in Maracay, Venezuela. We performed a prospective surveillance study of persons with ILI who presented for care at two hospitals in Maracay, Venezuela, from October 2006 to December 2010. A respiratory specimen and clinical information were obtained from each participant. Viral isolation and identification with immunofluorescent antibodies and molecular methods were employed to detect respiratory viruses such as adenovirus, influenza A and B, parainfluenza, and respiratory sincytial virus, among others. There were 916 participants in the study (median age: 17 years; range: 1 month--86 years). Viruses were identified in 143 (15.6%) subjects, and one participant was found to have a co-infection with more than one virus. Influenza viruses, including pandemic H1N1 2009, were the most frequently detected pathogens, accounting for 67.4% (97/144) of the viruses detected. Adenovirus (15/144), parainfluenza virus (13/144), and respiratory syncytial virus (11/144) were also important causes of ILI in this study. Pandemic H1N1 2009 virus became the most commonly isolated influenza virus during its initial appearance in 2009. Two waves of the pandemic were observed: the first which peaked in August 2009 and the second--higher than the preceding - that peaked in October 2009. In 2010, influenza A/H3N2 re-emerged as the most predominant respiratory virus detected. Influenza viruses were the most commonly detected viral organisms among patients with acute febrile respiratory illnesses presenting at two hospitals in Maracay, Venezuela. Pandemic H1N1 2009 influenza virus did not completely replace other circulating influenza viruses during its initial appearance in 2009. Seasonal influenza A/H3N2 was the most common influenza

    Trypanosoma cruzi infection in humans has been extensively studied in Venezuela; however, in reservoirs it has been less investigated. The objective of this study was to determine the seroepidemiology of T. cruzi in the state of Sucre, Venezuela. A cross-sectional and prospective study conducted in 95 towns and 577 dwellings in the 15 municipalies of the state of Sucre, Venezuela, from August to November, 2008. The evaluation of serum samples was performed with the CruziELISA kit and the multiple antigens binding assays (MABA). Furthermore, epidemiological surveys were applied to evaluate the risk factors. A total of dogs (average age of 2, 6 + 2.2 years, 226 males and 137 females) was evaluated. The combination of the ELISA / MABA tests detected 78 positive sera, sixty-nine negative and 10 of inconclusive results. The seroprevalence of the T. cruzi infection in dogs in the state of Sucre, was 22.1% (CI 95%: 20.58-22.4%). No significant statistic association was found between the T. cruzi infection in dogs and the evaluated epidemiological variables: hunting dogs that slept oudoors roaming freely in the populated center, sex of the animal and eating habits. The T. cruzi infection was associated to the age of canines, being significantly higher in the group of 0 to 3 years, when compared with older dogs. The high T. cruzi seroprevalence dected in dogs shows that in this región of Venezuela there prevails an important risk factor of transmissibility of this parasite to human populations.

    Chromoblastomycosis is a chronic granulomatous disease caused frequently by fungi of the Fonsecaea genus. The objective of this study was the phenotypic and molecular identification of F. pedrosoi strains isolated from chromoblastomycosis patients in Mexico and Venezuela. Ten strains were included in this study. For phenotypic identification, we used macroscopic and microscopic morphologies, carbohydrate assimilation test, urea hydrolysis, cixcloheximide tolerance, proteolitic activity and the thermotolerance test. The antifungal activity of five drugs was evaluated against the isolates. Molecular identification was performed by sequencing the internal transcribed spacer (ITS) ribosomal DNA regions of the isolated strains. The physiological analysis and morphological features were variable and the precise identification was not possible. All isolates were susceptible to itraconazole, terbinafine, voriconazole and posaconazole. Amphotericin B was the least effective drug. The alignment of the 559-nucleotide ITS sequences from our strains compared with sequences of GenBank revealed high homology with F. pedrosoi (EU285266.1). In this study, all patients were from rural areas, six from Mexico and four from Venezuela. Ten isolates were identified by phenotypic and molecular analysis, using ITS sequence and demonstrated that nine isolates from Mexico and Venezuela were 100% homologous and one isolate showed a small genetic distance. © 2015 Blackwell Verlag GmbH.

    The complex Caribbean-South America plate boundary zone in northern Venezuela, which extends from the Southern Caribbean Deformation Front in the north to the Guayana Shield in the south, is the result of stress transfer generated by the relative movement of 2 cm/a between both plates. The movement is active since Cretaceous time and progressively migrates from west to east, and the major movement is accommodated along a roughly 1000 km long strike-slip system in northern Venezuela, comprising the Oca-Ancon, San Sebastian and El Pilar right-lateral fault systems. Neotoectonic and paleoseismological investigations have been carried out during the last two decades, and recently have been complemented by research activities within the interdisciplinary projects BOLIVAR (Broadband Ocean-Land Investigations of Venezuela and the Antilles arc Region) and GEODINOS (Recent Geodynamics of the Northern Limit of the South American Plate). By means of geological, seismicity and structural seismic investigations, the structures of the strike- slip zones are investigated from their surface expression through the crust and into the upper mantle. High velocity zones are identified at crustal levels and near surface investigations give insight to the detailed tectonic structures.

    Many countries throughout the world are reporting an increasing number of imported malaria cases. It is now well documented that population movements play an important role in the spread and introduction of malaria infection in nonendemic areas. We evaluated the contribution of imported malaria to the overall malaria burden of disease in an already endemic malaria region in Venezuela, where malaria is exclusively caused by Plasmodium vivax. To estimate the magnitude of this contribution, we retrospectively analyzed cases of imported malaria in Sucre, Venezuela, during a 10-year period (1987-1998). During this period, 1,755 (3.8% of the total) cases of imported malaria were identified. Most of these cases were imported from the Meridian states into Sucre. In Latin America, a major factor in the reemergence and spread of malaria is human migration. Surveillance of imported cases of malaria in Venezuela would allow us to continue evaluating population migration dynamics and its epidemiologic impact on malaria transmission. Enhanced surveillance, such as the one shown in this study, would help the early identification of nonindigenous Plasmodium species and also of resistant Plasmodium strains with a potential to spread locally. Population mobility and imported malaria cases may add to the magnitude of malaria burden in some regions of Latin America. Furthermore, malaria treatment guidelines at local and national levels need to incorporate imported malaria cases in their treatment algorithms and into chemoprophylactic recommendations for travelers.

  16. Distribution, status, and traditional significance of the West Indian manatee Trichechus manatus in Venezuela

    1988-01-01

    Aerial and interview surveys were conducted in 1986 to determine the current distribution, status, and traditional significance of the West Indian manatee Trichechus manatus in Venezuela. Aerial surveys provided just eight tentative sightings in 73 hours of searching. These discouraging results may have been due to poor visibility, small populations, and perhaps reduced dry season manatee activity. Results of interview surveys, however, permitted a number of important generalizations. A remnant manatee population exists in Lake Maracaibo, but none occur along the more than 1500 km of Caribbean coastline. Abundance is greatest in eastern Venezuela bordering the Golfo de Paria, in the Orinoco Delta, and in the middle Orinoco and tributaries. Local market hunting in the middle of this century probably greatly reduced manatee populations in these areas. Recent protection laws, education efforts, and manatee scarcity have resulted in a declining interest in manatee hunting. Much excellent manatee habitat persists in these regions, and a continued decline in hunting could result in an optimistic outlook for future manatee populations if the incidental take in net fisheries is controlled. Traditional beliefs and legends concerning manatees in Venezuela, including hunting taboos, show that these animals remain a colorful part of the folk culture. However, manatee protection does not pose economic hardships or infringe upon traditional spiritual beliefs.

  17. Risk, Activism, and Empowerment: Women’s Breast Cancer in Venezuela

    Eid, Mahmoud; Nahon-Serfaty, Isaac

    2016-01-01

    The prevalence of breast cancer in Venezuela is particularly alarming, which is attributed to healthcare inequalities, low health literacy, and lagging compliance with prevention methods (i.e., screening and mammography). While the right to health is acknowledged by the Venezuelan constitution, activism beyond governmental confines is required to increase women’s breast cancer awareness and decrease mortality rates. Through the development of social support and strategic communicative methods enacted by healthcare providers, it may be possible to empower women with the tools necessary for breast cancer prevention. This paper discusses issues surrounding women’s breast cancer, such as awareness of the disease and its risks, self-advocacy, and the roles of activists, healthcare providers, and society. Specifically, it describes a four-year action-oriented research project developed in Venezuela, which was a collaborative work among researchers, practitioners, NGOs, patients, journalists, and policymakers. The outcomes include higher levels of awareness and interest among community members and organizations to learn and seek more information about women’s breast cancer, better understandings of the communicated messages, more media coverage and medical consultations, increasing positive patient treatments, expansion of networking of NGOs, as well as a widely supported declaration for a national response against breast cancer in Venezuela.

    Hepatitis E virus (HEV) causes a common infection in developing countries. HEV infection occurs as outbreaks, as sporadic clinical cases and as large epidemics in endemic areas. The objective of this study was to determine the presence of HEV infection in patients with clinical suspicion of hepatitis A virus (HAV) infection, referred to the Instituto Nacional de Higiene "Rafael Rangel" in Venezuela. Seventy-four sera were tested for anti-HAV and anti-HEV IgM antibodies. HEV-RNA was amplified from anti-HEV IgM positive sera using nested reverse transcription polymerase chain reaction for ORF1 (RNA dependent RNA polymerase region) and the amplicons sequenced for phylogenetic analysis. The frequency of anti-HEV IgM was 22/74 (30%) in the samples tested. Dual infection with HAV and HEV was found in 31% (12/39) of anti-HAV IgM positive patients. Viremia was detected in 3/22 (14%) of sera positive for anti-HEV IgM. Two HEV strains were classified as genotype 1 and one as genotype 3, which were closely related to Yam 67 (north of India) and US1 isolates from the USA, respectively. These findings suggest that HEV is an important cause of acute viral hepatitis in Venezuela as a single infection or co-infection with HAV, with high morbidity in children and young adults suggesting that this infection is endemic in Venezuela.

    Full Text Available Alo largo del siglo xx, el petróleo ha sido el elemento estructural que ha explicado la estructuración de la sociedad venezolana. Es una idea extendida que Venezuela es lo que la actividad petrolera le ha permitido ser. El presente trabajo se está interesado en estudiar cómo la construcción de la sociedad venezolana ha sido posible desde la óptica de productos intelectuales científico sociales. No interesa sólo una lectura teórica sino hacer una aproximación epistemológica que determine la existencia de un programa de investigación. Se utilizó el modelo VIE de José Padrón para analizar la obra de cinco científicos sociales clave que han estudiado el impacto social del petróleo en Venezuela: Rodolfo Quintero, Carmen Vallarino de Bracho, Roberto Briceño León, María Sol Pérez Schael y Fernando Coronil. Finalmente, se pudo demostrar que el único elemento en común entre estos estudios de investigación es el objeto, aunque cada uno de ellos tiene diferentes construcciones teóricas acerca de éste. De este modo, «petróleo y cambio social en Venezuela» no es todavía un programa de investigación

    We studied the wood anatomy of 29 species belonging to 10 genera of the tribe Detarieae, subfamily Caesalpinioideae and compare them with tribe Caesalpinieae. Detarieae is the largest of four tribes of Caesalpinioideae, with 84 genera, only eleven occur in Venezuela with species of timber importance. The specimens were collected in Venezuela and include wood samples from the collection of the Laboratorio de Anatomía de Maderas de la Facultad de Ciencias Forestales y Ambientales de la Universidad de Los Andes, Venezuela, and of the Forest Products Laboratory of the USDA Forest Service in Madison, Wisconsin, USA. The terminology and methodology used followed the IAWA List of Microscopic Features for Hardwood Identification of the IAWA Committee, 1989. Measurements from each specimen were averaged (vessel diameters, vessel element lengths, intervessels pit size, fibre lengths and ray height). The species of Detarieae can be separated using a combination of diagnostic features. Wood characters that provide the most important diagnosis and may be used in systematics of Detarieae include: intercellular axial canals, rays heterocellular, rays exclusively or predominantly uniseriate, prismatic crystals common in ray cells, irregular storied structure and fibre wall thickness. For comparative anatomy between Detarieae and Caesalpinieae: intercellular axial canals, heterocellular rays, rays exclusively or predominantly uniseriate, prismatic crystals common in ray cells (in Detarieae) and regular storied structure, fibres septate, fibre wall thick or very thick, rays homocellular, multiseriate rays and silica bodies (in Caesalpinieae). Axial parenchyma is typically a good diagnostic feature for Leguminosae, but not for Detarieae and Caesalpinieae comparisons.
