    Full Text Available En la Alta Guajira del Caribe colombiano, el cactus Stenocereus griseus es muy utilizado por la comunidad Wayuu. En el presente trabajo se caracteriza el sistema de uso y manejo, así como la demanda y oferta potencial de S.
    griseus en dos localidades. Una evaluación de los factores que afectan las poblaciones permitió determinar cinco
    categorías de daño, de las cuales las más importantes son las ocasionadas por corte con machete (tipo I, insectos (Tipo II y cabras (Tipo III. El uso actual de Stenocereus griseus se restringe a la colecta de la madera seca (“yotojoro” para construcción de viviendas tradicionales en la cultura Wayuu; la colecta de frutos en temporada de cosecha y la cosecha de tallos jóvenes para alimento de cabras y cercas vivas. La demanda anual de “yotojoro” está sujeta a la necesidad de construcción de los habitantes del área, que es definida como ocasional. El método actual de cosecha y extracción del mismo no está generando desequilibrio local en el mantenimiento de la especie. La demanda de cardones para cercas vivas y pastoreo es constante durante todo el año y generan el mayor impacto de daño. Finalmente, se discuten los principales problemas de conservación de la especie, y se recomienda establecer alternativas de manejo para las actividades de pastoreo, dado que con el ritmo actual de extracción, la población de cactus está expuesta a una inminente disminución local.

    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.

    1982-02-01

    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

    Pollen analysis of sediments from a high-altitude (4215 m), Neotropical (9°N) Andean lake was conducted in order to reconstruct local and regional vegetation dynamics since deglaciation. Although deglaciation commenced ˜15,500 cal yr B.P., the area around the Laguna Verde Alta (LVA) remained a periglacial desert, practically unvegetated, until about 11,000 cal yr B.P. At this time, a lycopod assemblage bearing no modern analog colonized the superpáramo. Although this community persisted until ˜6000 cal yr B.P., it began to decline somewhat earlier, in synchrony with cooling following the Holocene thermal maximum of the Northern Hemisphere. At this time, the pioneer assemblage was replaced by a low-diversity superpáramo community that became established ˜9000 cal yr B.P. This replacement coincides with regional declines in temperature and/or available moisture. Modern, more diverse superpáramo assemblages were not established until ˜4600 cal yr B.P., and were accompanied by a dramatic decline in Alnus, probably the result of factors associated with climate, humans, or both. Pollen influx from upper Andean forests is remarkably higher than expected during the Late Glacial and early to middle Holocene, especially between 14,000 and 12,600 cal yr B.P., when unparalleled high values are recorded. We propose that intensification of upslope orographic winds transported lower elevation forest pollen to the superpáramo, causing the apparent increase in tree pollen at high altitude. The association between increased forest pollen and summer insolation at this time suggests a causal link; however, further work is needed to clarify this relationship.

    A diffuse low deep microseismicity located overall between the Guajira peninsula and the Sierra Nevada de Santa Marta (SNSM) was registered with the recent installation (2008 to Present) of three seismological stations in northeastern Colombia by the Colombian Seismological Network (RSNC), but mainly with the Uribia station in (the) central region of La Guajira peninsula, The microseismicity is characterized by a great population of events with 1.2 Plantain Garden toward the north of the CP. This situation was originated of a new subduction development of the Nazca - Cocos plates toward the south and the west of the Panama arc; when this happened, the evolution of the Present - day configuration of the Nazca plate and Galapagos Spreading Center started. From the Early Pliocene, the BSMF and the Oca fault were reactivated: the BSMF, with a left lateral movement, and the Oca fault with a right lateral movement. This last mobility produces the cortical diffuse seismicity that we are showing here.

    2014-01-01

    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.

    Full Text Available 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 % onlyin 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.REPRODUCCIÓN DE Trachemys callirostris callirostris (EMYDIDAE EN AMBIENTES GENERADOS POR LA MINERÍAEN LA GUAJIRA, COLOMBIALa tortuga hicotea (Trachemys callirostris callirostris es una subespecie sometida a una alta extracción en Colombia, de la cualno se conoce nada sobre su reproducción en zonas altamente alteradas con bajo impacto por la cacería.

    Full Text Available El artículo está basado en la investigación sobre capital social en los resguardos indígenas wayuu del municipio de Riohacha (La Guajira –Colombia. 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.

    2012-01-01

    Full Text Available Venezuela confronta en la actualidad una grave crisis energética, causada por déficit de generación, saturación de las líneas de transmisión y distribución, y descuido general de la infraestructura eléctrica, incluyendo desprofesionalización de las empresas eléctricas del estado. Entre las opciones planteadas para complementar la creciente demanda de energía eléctrica, está la explotación de fuentes de energías renovables, entre ellas, la eólica. En este trabajo, en primer lugar, se hace una sucinta revisión de las distintas fuentes de energía empleadas en el mundo, destacando sus ventajas y desventajas, desde el punto de vista ambiental. Luego, a partir de los datos de vientos obtenidos en 30 estaciones meteorológicas distribuidas en el territorio nacional, se hace una evaluación preliminar de la potencia eólica estimada. Se concluye que los lugares con alta potencialidad para generación de energía eólica, se encuentran en la Isla de Margarita, la Guajira y en localidades insulares. Mediana potencialidad encontramos en la península de Paraguaná y algunos lugares del interior en los que se presentan sistemas de vientos regionales. El resto del país, no presenta buenas perspectivas para generación de energía eólica. La obtención de energía por medios eólicos, debe basarse en consistentes estudios meteorológicos, económicos, ambientales y de ingeniería.

    Full Text Available La Guajira es un sistema de surgencia explotado en el Caribe colombiano. 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 a través de la construcción del modelo, 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 1248,51 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%. Las flotas pesqueras afectan principalmente los recursos
    de las fracciones del nivel trófico III, la flota artesanal esta ejerciendo mayor presión sobre el pámpano, bonito y jurel, la flota parguera sobre pargos y meros y la flota industrial sobre las corvinas. Los resultados en los atributos de madurez del sistema sugieren que La Guajira es un

    La Guajira Peninsula lies within a large upwelling system along the South Caribbean Coast, created by the NE trade winds. In this location, sea surface temperature (SST) exhibits the lowest mean value and the highest variability in the whole Colombian Basin. The seasonal variation of SST explains up to 75 % of the total variability. La Guajira coastal zone also experiences the highest values of wind stress and wind stress curl, with the greatest annual and semiannual variability in the Colombian Basin. It has been shown that wind stress curl enhances the upwelling over the region. Near 90% of the variability of SST in La Guajira can be explained by the seasonality plus the first three EOFs interannual modes: the first, synchronous throughout the Basin, is dominant, and consists of a uniform interannual variation in phase with the North Tropical Atlantic Index; the second co-varies strongly with the second mode of wind stress curl; and the third reflects the role of the vertical atmospheric circulation cell associated with the Caribbean Low Level Jet off Central America. The inclusion of wind stress curl with its maximum offshore of La Guajira explains in part the extension of cool coastal water into the Colombian Basin, with advection in filaments, eddies and meanders. In order to complement the physical knowledge of La Guajira upwelling system, an analysis of water masses, sea surface height, Ekman suction, Ekman transport and coastal upwelling index (CUI) was performed. Hydrographic data was obtained from gridded climatologies from the National Oceanographic Data Center (WOD01); sea surface height anomalies from the Archiving, Validation, and Interpretation of Satellite Oceanography (AVISO) data; and wind data from the Cross-Calibrated Multi-Platform Ocean Surface Wind Velocity Product for Meteorological and Oceanographic Applications (CCMP). The upwelling forms a local water mass, La Guajira surface water (LGSW), with the mixing of subtropical underwater and

La ingobernabilidad se presenta como una crisis básicamente como crisis de legitimidad, crisis, de conducción política y crisis del Estado, es decir no se logra conformar un ambiente y escenario definido por la legitimidad y eficiencia que conlleva a un deterioro del sistema político a causa de la disfunción de los partidos como productores de representación y gobernabilidad en la sociedad venezolana a finales de los años ochenta. Finalmente analizamos el agotamiento del bipartidismo y la llegada del fenómeno Chávez y naturalmente la persistencia antes y ahora de indicadores de ingobernabilidad democrática.

Con el fin de caracterizarlas en época climática seca, en función del efecto en los cambios en estas variables y la profundidad, sobre su estructura, se midieron éstas variables estructurales en 15 estaciones de la plataforma continental de la Alta y Media Guajira situadas en uno de los tres siguientes intervalos de profundidad: somero (0-2 m, medio (2-4 m y profundo (>4 m. Mediante cuadrantes de 50 x 50 cm se determinó la cobertura de T. testudinum; en subcuadrantes de 20 x 20 cm se determinó la densidad de vástagos y en subcuadrantes de 20 x 10 cm se tomaron muestras para biomasa foliar, peso de epífitos, pastoreo y área foliar. Además, entre marzo y abril del 2006 se realizaron mediciones de producción y crecimiento foliar en Puerto Warreo (bahía Portete y el Cabo de la Vela. Los resultados obtenidos demostraron que la profundidad afectó el comportamiento de las praderas, observándose un mayor desarrollo en las praderas someras, reflejado en el incremento en la densidad foliar, densidad de vástagos, biomasa foliar, biomasa total, área foliar e índice de área foliar. Otros factores ambientales que también explicaron este comportamiento fueron la intensidad de la luz, el sustrato y la ubicación geográfica ya que las praderas con protección de bahía o ensenada, con alto contenido de

    In the continental Colombian Caribbean the conch resource exploitation and the status of snails populations has been poorly studied, which are reflected in the lack of fisheries management. This study assesses composition, population density and distribution of the gastropods species that make conch resource in La Guajira region. Underwater visual censuses for snails were performed between September-November 2009 in 145100x4m (400m2) transects, spanning a total area of 56920m2 between Riohacha and Cabo de la Vela. The study was complemented with the evaluation of composition, abundance and size of gastropods conch found in the discarded-by-fishermen shell mounds in 13 beaches. In October 2010 another 40 transects were evaluated (16 000 m2) from the Southern of Riohacha to the Camarones village (La Guajira). We found a total of 9911 snails belonging to 12 species, the most abundant being Strombus pugilis with 8 912 individuals and an average density of 1 538.4 +/- 3 662.6 ind./ha, followed by Vasum muricatum with 374 individuals and an average density of 51.8 +/- 91.2 ind./ha. Calculating the importance value index (IVI) for both living organisms as the empty shells on beaches, shows that Turbinella angulata is the most used species by artisanal fishermen in the region. Cassis madagascariensis and Cassis tuberosa are also important snail resources in the region (as suggested by the number of empty shells found in beaches), but its densities were low. Strombus gigas, with only three living organisms found in the area, presented the lowest abundance ever found in the Colombian Caribbean (0.52 +/- 3.6 ind./ha), showing that queen conch population in La Guajira cannot support commercial exploitation. The abundance of discarded S. gigas shells on beaches suggests resource exploitation in the recent past. Results remarks the urgency of implementing management plans for snail fisheries in the region. PMID:23885583

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. Results. 79.6% (n = 90 of the specimens were collected around the homes and 20.3% (n = 23 inside the homes, all corresponding to Triatoma maculata (Erichson, 1848. The natural infection indices with T. cruzi accounted for 43.5% for Marbacella and 36% for El Horno. Conclusion. This is the first reported capture of individuals of T. maculata, considered a secondary vector of Chagas disease in Colombia, naturally infected with T. cruzi in the municipality of Riohacha expanding the geographical distribution of the species in the department of La Guajira.

    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) PMID:12341015

    1995-06-19

    Venezuela`s enormous gas resource, combined with a new willingness to invite outside investment, could result in rapid growth in that industry into the next century. The development of liquefied natural gas exports will depend on the future course of gas prices in the US and Europe, but reserves are adequate to supply additional projects beyond the proposed Cristobal Colon project. Venezuela`s gas reserves are likely to increase if exploration for nonassociated gas is undertaken on a larger scale. The paper discusses gas reserves in Venezuela, internal gas markets, the potential for exports, competition from Trinidad, LNG export markets, and the encouragement of foreign investment in the gas industry of Venezuela.

Industry has tried to keep the Ministry of Environment Affairs involved as much as possible, says Danay Zoppi de Perez, corporate v.p. with Grupo Quimico. But industry was proud to be doing it anyway, despite the absence of government. It's a private, proactive initiative. Asoquim's program is based on the six Responsible Care codes. At the ceremony, 56 companies from Asoquim's membership of 150, which represents 90% of chemicals production in the country, signed on. Signatories include stateowned Petroquimica de Venezuela (Pequiven), domestic private-sector firms, and most of the multinationls operating in Venezuela.

    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)

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

    Science.gov (United States)

    Bilham, R. G.; Mencin, D.

    2013-05-01

    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

    Sources of demographic data for Venezuela include 11 population censuses conducted between 1873-1981, birth and death registration statistics, and the household sample survey. The average annual rate of population growth increase from 2.8% between 1920-40 to 3-4% thereafter. The population at the 1961 census was 7.52 million. According to preliminary data from the 1981 census, the population of 14.57 million is growing at an annual rate of 2.8%. 41.2% of the population is under 15 years old, implying a huge demand for educational and health services, housing and employment. The dependency rate in 1980 was 81.3% for the country as a whole, 100.4% in rural areas, and 76.0% in urban areas. The young age structure means that the population will continue to grow even if natality rates decline. The crude natality rate was estimated at 47.3/1000 for 1950-55, 36.0 for 1970-75, and 32.9 for 1980-85. Some rural areas still have natality rates of over 47/1000. The total fertility rate declined from 6.5 in 1950-55 to 4.1 in 1980-85. The decline in the natality rate reflects improving quality of life, availability of family planning services, urbanization, and access of women to productive activities and educational centers. The mortality rate was 12.3/1000 in 1950-55, 9.1 in 1960-65, in 1970-75, and has been estimated at 5.5 for 1980-85. Some rural areas have mortality rates of 8.1. The infant mortality rate was 50.2/1000 in 1971 and 34.3 in 1980. Life expectancy at birth is about 69 years. During the 1920s, Venezuela unerwent expansion in infrastructure and technological utilization, generating rapid urbanization. 39.2% of the population was urban in 1941, compared to 78.8% in 1980. The significance of urbanization in Venezuela is due to the rapidity as well as the diffusion of the process. The household sample survey for the 2nd half of 1980 indicated a total of 8.16 million employed and an activity rate of 32.1% overall, 46.4% for males and 17.7% for females. The

We report the activity at the Metropolitan Blood Bank (the largest one of the country) in the period 1999-2003: 597 therapeutic procedures were performed in 171 patients, during 212 crisis episodes. The average age was 38 +/- 16 years, 65% male and 35% female. Most of the therapeutic procedures were therapeutic plasma exchange for hematology diseases (mainly thrombotic thrombocitopenic purpura and hemophilia inhibitors), including 184 therapeutic procedures with the Autopheresis-C (Baxter Healthcare Corp., Deerfield, IL). Most common adverse effects (3.9%) were hypotension and allergic reactions to the plasma. PMID:15880361

  13. Venezuela natural gas outlook

    International Nuclear Information System (INIS)

    This paper reports on the natural gas outlook for Venezuela. First of all, it is very important to remember that in the last few years we have had frequent and unforeseen changes in the energy, ecological, geopolitical and economical fields which explain why all the projections of demand and prices for hydrocarbons and their products have failed to predict what later would happen in the market. Natural gas, with its recognized advantages over other traditional competitors such as oil, coal and nuclear energy, is identified as the component that is acquiring more weight in the energy equation, with a strengthening projection, not only as a resource that covers demand but as a key element in the international energy business. In fact, natural gas satisfies 21% of overall worldwide energy consumption, with an annual increase of 2.7% over the last few years, which is higher than the global energy growth of other fossil fuels. This tendency, which dates from the beginning of the 1980's, will continue with a possibility of increasing over the coming years. Under a foreseeable scenario, it is estimated that worldwide use of natural gas will increase 40% over the next 10 years and 75% on a longer term. Specifically for liquid methane (LNG), use should increase 60% during this last decade. The LPG increase should be moderate due to the limited demand until 1995 and to the stable trends that will continue its use until the end of this century

  14. Uranium prospection in Venezuela

    International Nuclear Information System (INIS)

    Full text: The worldwide increase of energy consumption and high fossil fuels costs generates the necessity of alternative energy sources. At present, nuclear energy is substituting the use of hydrocarbons, due to its high performance and contribution to environmental preservation, since it avoids the emission of greenhouse gases. Uranium consumer countries will continue to increase its demand, and even, is expected the incorporation of new reactors in countries with emerging economies. Base in the statement considered above, investment in new mineral deposit is justified. At present, some countries are motivated to start or continue the uranium exploration because of the evolution of the nuclear energy industry. Venezuela started exploration in the mid of 1970s, and stopped at 1980s. Our purpose is to evaluate uranium resources potential in the country, both for own use or export. In order to locate potential areas for exploration, in this initial phase all data from previous period is being compiled, incorporating information from oil exploration (seismic data, wells profiles, etc.). This information is been digitalized to generate a database into a geographical information system. Preliminary results show three areas of interest, where new geological, geochemical and geophysical surveys are propose. At this time, we do not have specific information about ore reserves, but we have anomalous areas that have been established as starting points to continue the uranium exploration in the country.

    Full Text Available El siguiente artículo tiene como objetivo principal analizar la tendencia y evolución del desarrollo humano en Venezuela para el periodo 2000-2010. Se abordó la investigación enmarcada en una metodología de tipo positivista con técnicas estadísticas. Se concluyó que los recursos escasos y las dificultades históricas exigen un incremento de esfuerzos presupuestarios y de gestión, en cantidad, calidad y transparencia por parte del Estado a través del gasto público. En los últimos años, el Estado no ha aprovechado plenamente el potencial de la política fiscal y los periodos de bonanza económica, precedidos por los auspiciosos auges petroleros, para fomentar, estimular y consolidar el desarrollo humano que permita a la población en general tener calidad de vida cónsonos con una sociedad conducente al bienestar general sostenible y permanente. Esto se explica por diversas limitaciones y retos afrontados, como la falta de diversificación del financiamiento y gasto público, la exigua carga fiscal, la corrupción dentro de la praxis política, la estructura mayormente regresiva del sistema de recaudación, el gasto público y social insuficiente e inequitativo.

    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.

  8. Venezuela opens up to explorers

    International Nuclear Information System (INIS)

    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)

  13. Importance of energy efficiency in Venezuela

    International Nuclear Information System (INIS)

    Venezuela's economic development relies heavily on oil. The nation's energy production equals 3.5 million barrels of oil equivalent (boe) per day. Oil comprises 71% of the energy Venezuela produces, natural gas 20%, hydro 9% and coal 1%. Of the energy produced, Venezuela exports three quarters and consumes the remainder. Over 99% of Venezuela's energy exports are crude oil and oil products. Economic problems have constrained Venezuela's development in recent years. Saddled with an external debt of $US 32 billion, Venezuela will continue to encounter barriers for years to come. The nation is, however, in the process of restructuring its economy. As part of this process, the Venezuelan government has begun to integrate opportunities for improving the efficiency of its energy use. As a major oil producer and exporter, Venezuela is conscious of its responsibility to the international community to limit its emissions of energy-related CO2 into the atmosphere. For this reason, the Venezuelan government is in the process of creating a program to conserve and ration the use of energy. This effort incorporates a number of measures including the substitution of natural gas for liquid fuels for all end uses (including transportation activities), the increased reliance on hydropower in the generation of electricity and the reduction of waste in the production of natural gas to 2% of the economically recollectable volume

  14. Venezuela: World Oil Report 1991

    International Nuclear Information System (INIS)

    This paper reports on Venezuela's expansion by state oil company PDVSA has gone from a mere concept a year ago to a well-defined plan. The five-year project that began this year and runs through 1995 received a $4-billion upgrading last fall to $25 billion. Money will be spent in increments of $5 billion/year, and all sectors are involved. Largest share, about $10.5 billion, will go to upstream projects, with $6 billion to be invested in refining, $6 billion in petrochemicals, $1.5 billion in coal and $800 million in domestic marketing. PDVSA intends to finance most of the spending directly from its cash flow. The upstream spending will go toward boosting oil production to more than 3.6 MMbpd by the beginning of 1996, with capacity topping at 4.2 MMbopd. Such heavy spending should prove a boon to the Venezuelan economy. The oil industry constitutes 23% of Venezuela's GNP, accounts for 75% of governmental revenues and produces 70% of the nation's annual foreign exchange earnings. The Ministry of Planning already is forecasting a 7% leap in real growth of the GNP this year

  15. Quality of democracy in Venezuela

    2013-01-01

    Full Text Available 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. Future scenarios, after the 2012 presidential election result, include reinforcement of authoritarian trends, open militarization, liberalization and institutional strengthening, or long term volatility and polarized conflict. All scenarios are contingent on the health of President Chávez, who is a central unifying factor for his movement and regime

RESULTS: The national database held records of 1.710 patients; 3.8% had onset of the first symptoms before age 18. 46.7% were boys, yielding an F:M ratio of 1.13:1. Many children had a disease onset characterized by motor impairment (30.7%, brainstem/cerebellum and spinal cord affectation (27.6%, headache (26%. Less frequent symptoms were sensory symptoms (8% and optic neuritis (7%. DISCUSSION: Pediatric MS patients in Venezuela represent a significant proportion of all MS cases. The clinical pattern is characterized by motor symptoms at onset, and predominantly monosymptomatic presentation with a relapsing-remitting pattern. This is the first systematic attempt to estimate the prevalence of pediatric MS in 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.

  7. Can Venezuela's oil sector endure Chavez' ambitions any longer?

    International Nuclear Information System (INIS)

    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.

    International Nuclear Information System (INIS)

    This paper reports that Venezuela will accept bids under a second round next year from private foreign and domestic companies for production contracts to operate marginal active as well as inactive oil fields. The first such round came earlier this year, involving about 55 other marginal, inactive fields. It resulted in two contractors signed with domestic and foreign companies. It represented the first time since nationalization of the petroleum industry in Venezuela in 1976 that private companies were allowed to produce oil in the country. A public bid tender was expected at presstime last week

  16. Incorporation of island-arc rocks into a Caribbean subduction channel: Geochemical constraints from eclogite boulders and greenschist rocks, Guajira region, Colombia

    Weber, M.; Cardona, A.; Altenberger, U.; Garcia-Casco, A.; Valencia, V.; Tobón, M.; Zapata, S.

    2009-12-01

    Characterization of the protoliths of a subduction-accretion complex can provide major insights into the dynamics of the subduction channel. Geochemistry of eclogites found as boulders in a Tertiary conglomerate from the Guajira Peninsula, Colombia, indicate that these rocks are mainly metamorphosed basalts. A negative Nb-anomaly and flat to enriched REE patterns suggest that the eclogite protoliths evolved in a subduction related tectonic setting, with island arc affinities. The geochemical characteristics are similar to low-grade greenschists from the nearby Etpana Formation, which is interpreted as part of a Cretaceous intra-oceanic arc. This further supports evidence that the deposition and metamorphism of these units record the ongoing Late Cretaceous continental subduction of the South American margin beneath the advancing Caribbean arc. This gave way to an arc-continent collision between the Caribbean and the South American plates. Arc-rocks were incorporated into the subduction channel and the accretionary wedge, either though influx of tectonically eroded arc material (subduction erosion) or incorporation into the accretionary wedge during arc-continent collision.

    Full Text Available To assemble Volkswagen cars for the Venezuela market, a large hall has been built, which is fitted with full facilities for its purpose, such as painting and greasing installations, and large parking area for the finished vehicles. 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. Lo más notable es la cubierta de la gran nave, formada por una serie de láminas parabólico-hiperbólicas de hormigón armado, de planta rectangular, inclinadas ligeramente hacia el norte para formar un perfil en diente de sierra.

    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

  4. National Oil Companies: the view from Venezuela

    International Nuclear Information System (INIS)

    National oil companies were key elements in the initial OPEC strategy and they brought a de-integration of oil industry. These companies have tried to move from crude marketing to product marketing through new investments at home and abroad in order to get higher value added and more secure markets for crude. Low prices bring new challenges. Venezuela's answers are strategic associations, operating contract for marginal fields and profit sharing agreements. (Author)

    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?

    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.

    This paper presents an analysis of vertebrate roadkills in five different habitats of tropical South America. Observations of vertebrate roadkills were conducted in 1978, on a 572 km road between Caracas and Mantecal/Apure in Venezuela, during the rainy season (June-October). During five passages on this route, which includes five distinct habitats, 79 vertebrate carcasses - mammals and reptiles - were found. If we assume that the carcasses remain for two days on the road, vehicles can be exp...

  7. Quaternary Faults and Stress Regime of Venezuela

    Directory of Open Access Journals (Sweden)

    2006-12-01

    Full Text Available Spatial configuration of Quaternary active tectonic features along the southern Caribbean plate boundary suggests that the region is subject to a compressive strike-slip (transpressional senso lato regime, characterized by a NNW-SSE maximum horizontal stress (sH=s1 and/or an ENE-WSW minimum (s h=s3 or s2 horizontal stress. Stress inversion applied to fault-plane kinematic indicators measured essentially in Plio-Quaternary sedimentary rocks confirms this tectonic regime. Accordingly, this stress regime is responsible for the Quaternary activity and kinematics of six sets of brittle features along northern Venezuela (from Colombia in the west to Trinidad in the east: (1 east-west rightlateral faults, (2 NW right-lateral faults -acting as synthetic Riedel shears-, (3 ENE to east-west dextral faults -P shears-, (4 NNW normal faults, (5 almost north-south left-lateral faults -antithetic Riedel shears- and (6 mostly subsurface ENE reverse faults associated with folding of the same orientation. Brittle deformation conforms to the simple shear model, although not all the deformation can be accounted for it since strain partitioning is also taking place because regional folding and thrusting are due to the normal-to-structure component of the relative slip vector between the Caribbean and South America plates. On the other hand, the maximum horizontal stress in western Venezuela, particularly in the Maracaibo block and south of the Oca-Ancón fault, progressively turns counter-clockwise to become more east-west oriented, producing left- and right-lateral slip along the north-south striking and NE-SW striking faults, respectively. The orientation and spatial variation of this regional stress field in western Venezuela results from the superposition of the two major neighboring interplate maximum horizontal stress orientations (sH: roughly east-west trending stress across the Nazca-South America type-B subduction along the pacific coast of Colombia and NNW

    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.

    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.

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 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.

    Nuramy J. Gutiérrez

    2008-07-01

    Full Text Available This work reviews social changes occurring in Venezuela during the last two decades, examining how they led to the development of a new health policy. Initially, the political context of the nineties is examined; this was a time when the neoliberal politics of the 1980’s had a demonstrable impact on the living conditions and health status of the population. By 1999 social and political events led to a new Constitution which provided the juridical and legal framework for a new health policy. The conceptualization of health and the model of health care which arose from the constitutional process are considered, as well as the reaction of the dominant economic and political sectors to the new policies imposed by constitutional mandate. The emergence of Barrio Adentro and other social missions is analyzed as an essential factor in the initiation of structural changes within the country and its health institutions. The Barrio Adentro program is described in detail, along with key steps in the development of the Venezuelan National Public Health System. Finally, the impact of these new health policies on the quality of life of the Venezuelan population is delineated.

    A very important increase in the costs of the edition of scientific journals has taken place in Venezuela, due to difficulties in obtaining imported free acid paper and other materials used for handling documents. Like other journals, Investigaci6n Clinica has been considering switching completely to a digital publication format; however there are several reasons that prevent us to doing it at this time: the journal is distributed in printed form to many national institutions, which do not have immediate access to digital information. In addition, there exists a commitment of shipment of printed issues for some international indices and in exchange with other national and foreign journals, whose printed format we receive. Another important aspect is that our University maintains a weak technological platform that makes difficult the immediacy required for the interchange with authors and consulted referees of received papers; and there is a latent danger of limitations in the use of digital technologies, due to current national politic problems. Consequently, we need to continue with the printed format, but must reduce the amount of printed issues, so as not to limit the number of papers published in each edition. Nevertheless, there is an ever increasing number of contributions from foreign researches and Investigaci6n Clinica has been recently included in two new international indices, the SEIIC from Argentina and the Infobase Index from India, reasons that obligate us to maintain our levels of excellence and commitment to our authors and readers.

    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.

    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.

    It is study the feasibility of development of the alternative energies, AE, in Venezuela based on its potential of exploitation, the analysis of its energetic system, and the attitude of the State before the AE. 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. It is concluded that only with a change of attitude of the State and the concourse of all the actors involved in the sector, the {sup c}lean energies{sup w}ould be able to have an important weight in the national energetic balance.

  20. Quaternary Faults and Stress Regime of Venezuela Fallas y campo de esfuerzos cuaternarios de Venezuela

    Directory of Open Access Journals (Sweden)

    F.A. Audemard M.

    2006-12-01

    Full Text Available Spatial configuration of Quaternary active tectonic features along the southern Caribbean plate boundary suggests that the region is subject to a compressive strike-slip (transpressional senso lato regime, characterized by a NNW-SSE maximum horizontal stress (sH=s1 and/or an ENE-WSW minimum (s h=s3 or s2 horizontal stress. Stress inversion applied to fault-plane kinematic indicators measured essentially in Plio-Quaternary sedimentary rocks confirms this tectonic regime. Accordingly, this stress regime is responsible for the Quaternary activity and kinematics of six sets of brittle features along northern Venezuela (from Colombia in the west to Trinidad in the east: (1 east-west rightlateral faults, (2 NW right-lateral faults -acting as synthetic Riedel shears-, (3 ENE to east-west dextral faults -P shears-, (4 NNW normal faults, (5 almost north-south left-lateral faults -antithetic Riedel shears- and (6 mostly subsurface ENE reverse faults associated with folding of the same orientation. Brittle deformation conforms to the simple shear model, although not all the deformation can be accounted for it since strain partitioning is also taking place because regional folding and thrusting are due to the normal-to-structure component of the relative slip vector between the Caribbean and South America plates. On the other hand, the maximum horizontal stress in western Venezuela, particularly in the Maracaibo block and south of the Oca-Ancón fault, progressively turns counter-clockwise to become more east-west oriented, producing left- and right-lateral slip along the north-south striking and NE-SW striking faults, respectively. The orientation and spatial variation of this regional stress field in western Venezuela results from the superposition of the two major neighboring interplate maximum horizontal stress orientations (sH: roughly east-west trending stress across the Nazca-South America type-B subduction along the pacific coast of Colombia and NNW

    Sobiesiak, M.; Palme de Osechas, C.; Choy, J. E.; Morandi S., M. T.; Campo, M.; Granado Ruiz, C.

    2001-12-01

    Venezuelas tectonic setting as part of the plate boundary between the Caribbean and the South American plate causes two major seismologically active fault systems: the roughly west - east trending strike slip fault system along the coast with numerous sub-parallel faults and the Bocono fault system, which dominates the Venezuelan southwest - northeast striking Andes. The main Bocono fault reaches a total length of about 500 km and has a width of approximately 100 km between the southern and northern baseline of the mountain slopes which are marked by inverse faults. This is believed to be due to strain partitioning, a concept which seems to apply as well to the Bocono fault system. The whole fault system is characterized by a high seismicity rate of small scale and intermediate event magnitudes ranging from 1.5 to 6.3 in the last fifty years. In this study we would like to present an investigation on 39 focal mechanism solutions and a b-value mapping of the Andean region with the main goal to throw light on the stess and strain situation. For recompiling the focal memchanisms calculated from first motion polarities, various sources had to been used: seismograms from stations of the local and regional networks of the Seismological Center of ULA, the national seismic network operated by FUNVISIS, the seismic network Lago Maracaibo of PDVSA and the local seismic network of DESURCA. For the b-value mapping we used the two catalogues of ULA and DESURCA of which the last one registered more than 6500 events from 1994 to 1999. The set of focal mechanism solutions studied showed normal, strike slip, and reverse faulting mechanisms concentrated in distinct areas of the Bocono fault system and thus resulting in a zonation also supported by the determinations of the azimuths of the maximum horizontal stress SHmax. This hypothesis of the zonation of the Andes region is strongly supported by the results of the b-value mapping. The zonation as seen in the varying major stress

  14. Can Venezuela's oil sector endure Chavez' ambitions any longer?; Kan Venezuela's oliesector Chavez' ambities nog langer dragen?

    Energy Technology Data Exchange (ETDEWEB)

    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. De verarmde massa's van Venezuela steunden Chavez nog in de verkiezingen in

    Full Text Available La realizzazione di linee e di stazioni dell’Alta Velocità, oltre ad influire sullo sviluppo urbanistico delle aree interessate, sta cambiando radicalmente le relazioni spazio-temporali fra i diversi centri urbani connessi dalla rete del trasporto su ferro. Da un lato sono mutate le funzioni assunte dai contenitori-stazione e dall’altro sta mutando la domanda di trasporto che promuove, per le tratte coperte dalle linee dell’Alta Velocità, il treno rispetto all’aereo e alla macchina. In Italia, sulla scia del modello francese, il Gruppo Ferrovie dello Stato RFI, al fine di rendere più confortevole ed efficiente il viaggio sui treni ad Alta Velocità, ha dotato i nuovi treni di numerose innovazioni tecnologiche. Per quanto riguarda l’utilizzo di nuove tecnologie lungo le linee dell’A.V., l’articolo individua la variazione delle abitudini degli utenti al mutare dell’offerta dei servizi predisposti dalle compagnie trasportistiche. La tecnologia utilizzata sui nuovi treni dell’Alta Velocità cambia dunque il concept del viaggio: il valore aggiunto della tecnologia Wi-Fi introdotta sui treni rende la scelta del trasporto su ferro più produttiva rispetto gli altri modi di trasporto quali la macchina o l’aereo. La finalità dell’articolo è da un lato individuare il ruolo urbano assunto delle stazioni dell’Alta Velocità e dall’altro evidenziare come al mutare dell’offerta di trasporto, in termini di servizi offerti ad alto contenuto tecnologico, muta contestualmente anche la domanda di trasporto sul territorio e come tutto questo incida dunque sul governo delle trasformazioni territoriali. Questo è il nuovo importante ruolo della pianificazione: alcune delle nostre più importanti città stanno radicalmente trasformandosi proprio inserendo nei loro cuori le stazioni dell’Alta Velocità come elementi-chiave di accessibilità, vitale per la competitività in tutti i settori economici.

    Full Text Available This article looks at the traditional cake making in the Terra Alta (Catalonien area linked to festivities, and in particular the pastries usually made. In this area the pastries are known as cócs, a word common to Terra Alta and the neighbouring districts of Ribera d'Ebre and the Priorat. Locally produced mistelle, sweet or rancid wine is served with the pastries. Nowadays, the bakeries and cake makers in the area's towns and villages also produce traditionally crafted products, that used only to be homemade.The article, resulting from the final degree project produced by the author for her Humanities degree at the UOC, offers a privileged look at the richness of the Terra Alta in terms of its gastronomic history, customs and its high regard for its cakes. The author, who has previous experience in the field, places the specific aspects of Terra Alta cake making in the context of the Mediterranean cultures with common roots dating back to the ancient and medieval worlds and which still have an easily identifiable "family feel", whilst looking, from an ethnographic point of view, at what she calls the "world of wheat" in the area, (the dough for bread, the craft of the baker, the ovens and other tools, and the associated traditions, among other things. In short, she rescues a living part of the local day-to-day activities and places it under the microscope of food history, whilst providing information that may well be of interest for study from other points of view.

    International Nuclear Information System (INIS)

    Faced with the need to import increasing volumes of crude oil and the desire to avoid over-dependence on the Middle East, the United States is looking to its own hemisphere for more oil. Unfortunately for Washington, the continent's largest oil exporter does not appear to want to co-operate. Venezuela's President, Hugo Chavez, wants to reduce his country's political and economic ties with the US and is seeking other markets for its oil. He has also picked a fight with US oil companies operating in Venezuela, disputing their taxes and refusing to approve their upstream investment programmes, giving rise to fears that oil and gas production will not grow as planned, thereby reducing future export levels.

    Directory of Open Access Journals (Sweden)

    María Alejandra Añez Castillo

    2010-12-01

    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.

  8. Building a medicine bank for Venezuela. AIDS treatment access.

    1997-01-01

    A partnership began in 1994 between United Against AIDS International (UAAI) of New York and Accion Ciudadana Contra el SIDA (ACCSI) of Venezuela has led to the development of a volunteer infrastructure including medicine and medical supply donors, airlines, truck drivers, customs officials, storage facilities, and medical personnel to bring treatment to people with AIDS (PWA) in Venezuela. Renate Koch, ACCSI director, began bringing medications home to Venezuela in early 1994, following a visit to New York City, where she met with representatives of ACT UP], the Global Network of People with AIDS, and other New York-based HIV/AIDS associations. Hugh Ward, who founded UAAI to provide HIV/AIDS drugs to PWA in Venezuela, later met with Koch and several other nongovernmental organizations in Caracas. Ward explained that most unused medicines and treatments given to people with AIDS in the US are thrown away after the patient has died or when the patient's health condition demands an alternate treatment. A network of New York-based AIDS organizations and doctors' groups now collects the medicines returned to them by PWA for donation to the medicine bank program. Once the medicines are received in Caracas, they are stored at Accion Ecumenica health clinic for distribution to PWA. While there is always a need for more medicines and supplies, the current network is able to back-stock enough quantities to ensure that patients will receive consistent and sustained treatment. Limited quantities of retrovirals and protease inhibitors are included in the medicine bank. PMID:12321757

En Venezuela el desarrollo endógeno es un mecanismo dentro del proceso para la construcción de nuestro socialismo. Por lo tanto este debe partir por el debate teórico y filosófico de los fundamentos que deben sustentar esta nueva economía y sociedad. Por eso el propósito de este trabajo tiene que ver con los cambios ocurridos en la administración publica, la dialéctica entre centralización y descentralización, la ocupación del territorio en Venezuela, y los espacios alcanzados por la organización popular, para entender el papel que juegan en el desarrollo armónico de las comunas y la sociedad socialista.

  15. Violence in Venezuela: oil rent and political crisis

    Directory of Open Access Journals (Sweden)

    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).

  18. Paleoseismology in Venezuela: Objectives, methods, applications, limitations and perspectives

    Audemard M., Franck A.

    2005-10-01

    The privileged location of Venezuela along an active interplate deformation belt, despite of being a "so-called" developing country, has led to a long paleoseismic tradition as attested by 45 trench assessments since 1968. Since then, a first 2-trench study was carried out by the American Woodward-Clyde company across the Oca fault at Sinamaica. Since 1980, all further paleoseismic studies have been performed by FUNVISIS and the Uribante-Caparo hydroelectric project (southern Mérida Andes) became their first assessment where 22 huge trenches were bulldozer-dug. Except for these Compañía Anónima de Administración y Fomento Eléctrico (CADAFE) financed trenches and two others, all other assessments were for Petróleos de Venezuela S. A. -PDVSA-. In this paper, geographic and geologic factors, as well as logistic limitations, conditioning success in paleoseismic studies by trenching, shall be discussed based on the Venezuelan experience developed over the years. The scientific contribution of this approach refer to: confirmation of Holocene fault activity, slip-per-event and average slip rate of a given fault (or segment), seismic potential (repeat of maximum credible earthquakes) of known faults, fault segmentation, fault interaction as consequence of stress loading by stick-slip on contiguous faults, time-space distribution of seismic activity along a given tectonic feature, seismotectonic association of historical earthquakes and landscape evolution on the short term and its implications on the long-term evolution (poorly discussed since this is really part of the field of Neotectonics). In recent years (since 1999), a new approach has been introduced in Venezuela consisting in complementing the seismic history derived from trenching studies with the evaluation of seismically induced perturbations in the continuous Quaternary sedimentary record of (either active or fossil) lakes. The future of this discipline in Venezuela heads to more trenching and lake

  6. Venezuela positioning itself to take key market role in wake of Gulf War

    International Nuclear Information System (INIS)

    This paper reports on Venezuela which continues efforts to position itself in world markets to capitalize on fallout from the Persian Gulf war. The central government and state oil company Petroleos de Venezuela SA have accelerated already ambitious plans to expand activities in upstream and downstream oil and gas sectors. Pvdsa has sharply increased its 1991-96 investment program from the level planned at the end of last year. The goal is to put Venezuela on a par with major Persian Gulf oil exporters in terms of productive capacity. Linchpin of those efforts could well be further steps toward privatization of Venezuela's oil sector. For the first time since nationalization in 1976, private foreign and domestic companies are being permitted to participate in Venezuelan exploration and development. In addition, the government is trimming the onerous tax burden the oil sector has carried in Venezuela, as well as its heavy subsidy of domestic petroleum products

  7. TransForm: TransAlta 2000 annual report

    International Nuclear Information System (INIS)

    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. TransAlta also has an excellent track record in developing power generation projects internationally. refs., tabs., figs

  15. Zonation of hydric regimens in Venezuela based on rainfall characteristics

    Science.gov (United States)

    Lobo, D.; Verbist, K.; Gabriels, D.; Puche, M.; Bracho, G.; Soto, G.; Santibañez, F.

    2012-04-01

    The climate in Venezuela is a product of a complex combination and interaction of meteorological and geographical factors such as the geographic location either north of Ecuador or in the tropics, and the presence of warm waters north and northeast, a vast tropical moist forest south and a mountain range west. In order to delimit the different climatic zones in Venezuela, a zoning of water regimes were used to classify climate indices primarily on rainfall parameters. A first index used was the length of a dry period, corresponding to the number of months in the year when precipitation is less than half of the reference evapotranspiration. Another index was the Aridity Index (Ia) proposed by UNEP (1997), for which calculations were based on values of average annual rainfall of the stations of the FAO database (1984, 2000). The reference evapotranspiration (ETo) was calculated by the CIRH program version 2.0 (Santibanez, 2005), which allows the calculation of ETo by the FAO (Allen et al.1998) or by the original Penman-Monteith formula, by Thornthwaite (1948), Turc (1961) or by Ivanov (1996). The results show that the distribution of the climatic regimes of Venezuela is determined by rainfall patterns. The central region is dominated by a sub-humid regime surrounded by a humid regime. The southern region is dominated by hyper-humid, hydric and hyper-hydric regimes, as well as the most western and eastern regions. In the northern and central-western regions the semiarid, arid and hyper-arid regimes dominate.

  16. Technology for Salt Production in the Mixteca Alta

    Directory of Open Access Journals (Sweden)

    2015-01-01

    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.

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."

    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

  8. Venezuela No. 1 oil import source in S. America

    International Nuclear Information System (INIS)

    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

  9. Soil gas radon concentration across faults near Caracas, Venezuela

    International Nuclear Information System (INIS)

    SSNTD were used across tectonic features of different degree of activity and lithology in four localities north of Caracas, Venezuela. The homemade dosimeters with LR115 film were buried 20-30 cm in the ground. This cheap and low- tech method proved very useful to understand the tectonic features involved, measuring higher Radon concentration above traces of active faults while in old and sealed faults the results only show the effect of the surrounding lithology. Radon concentration range is 4.3 - 27.2 kB/m3. (Author)

    A historical compilation, initiated with Dr. Lorenzo Campins y Ballester in 1773, covering the teaching aspect, and culminated with the creation of the first postgraduate in psychiatry at the Central University of Venezuela in 1939, is made. On the assistential side, the way in which patients were treated during colonial times is mentioned, introducing the attempts which were carried out up to 1892, when Dr. G.T. Villegas Pulido ordered the moving of 30 patients to the remodeled military hospital, becoming this latter institution the Psychiatric Hospital of Caracas. The influence of private institutions on both teaching formation and assistential level is also mentioned.

    Full Text Available En este trabajo se aborda la dinámica de la aplicación del modelo neoliberal en Venezuela y sus consecuencias económicas, políticas y sociales hasta llegar a la propuesta de construir el socialismo del siglo XXI. Para ello hacemos una breve retrospectiva de lo que ha sido la sociedad venezolana desde la década de 1970, del auge rentístico hasta llegar a la crisis de la década de 1980 y la inserción del programa neoliberal. La aplicación del modelo neoliberal en Venezuela, como en buen parte de América Latina, no fue un proceso fácil, por el contrario produjo fuertes conflictos y contradicciones. Asimismo, el periodo iniciado en 1999 con la llegada de Hugo Chávez al poder está cargado de dificultades y obstáculos, pero sin lugar a duda ha sido un proyecto contra el neoliberalismo. Por ello el objetivo de este trabajo es revisar el proceso venezolano hacia el socialismo.

    We describe a new species of Buthid scorpion, Tityus quirogae, from the Turimiquire mountains, eastern side of the La Costa range, Monagas and Sucre States, Venezuela. It is morphologically similar to T. nematochirus and T. meridanus. It differs from these species in the distribution of the dorsal femoral trichobothria and in the following combination of characters: (1) I caudal segment with two parallel ventral keels. Caudal segments II to IV with ventral keels that are double in the extremes of the segments and single in the middle, (2) noticeable sexual dimorphism, especially in pedipalp shape; the male chelae are markedly thin and long, (3) number of pectineous teeth (male: 18 in each pecten; female: 18 in the right pecten and 19 in the left one), and (4) number of denticle rows in the movable finger of the right chela (16 in both sexes).

In Sucre,prevalence of adult parasites in opposums was 13. 33% with an intensity of 1.50 parasites per individual; in Montes, prevalence was 31.88% with a parasite load of 6.82 parasites per host. Prevalence of metacercariae in crabs was 17. 98% in Montes and 4.07% in Sucre. No significant differences between prevalence, intensity and gender of the crabs was found in any of the two areas, but there was a positive and significant correlation with size. In Sucre, the crab parasite burden was higher, 8.20%, than in Montes,5.31%. It was concluded that the intensity of infection was higher in female crabs and in those of a larger body size. These results indicate the existence of zoonotic contamination in both areas, and the need tocontinue investigating in order to determine relevant elements of this parasitic interrelation.

  20. Venezuela recasts itself as a new frontier in the Americas

    International Nuclear Information System (INIS)

    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

    Full Text Available La sedimentación del delta del río Orinoco podría influir en las relaciones geopolíticas entre Venezuela y Trinidad-Tobago, ya que los espacios deltaicos abarcan superficies cada vez más extensas, y de esta manera generan un acercamiento progresivo entre territorio venezolano y trinitario. Al norte y sur de Trinidad existen ciudades importantes como Puerto España, Point Fortín y La Brea, con recursos e industrias vinculadas a la actividad petrolera vitales para su desarrollo económico, que mantienen relaciones de intercambio comercial y cultural con centros poblados situados en el estado Delta Amacuro y la península de Paria, conformándose así la frontera entre Venezuela y Trinidad-Tobago, a pesar de existir barreras en cuanto a idioma, cultura y costumbres. Para el Estado venezolano, el delta del río Orinoco constituye la fachada atlántica que proyecta su Zona Económica Exclusiva y por este motivo, Venezuela y Trinidad-Tobago comparten un espacio que posee recursos marinos, mineros y pesqueros de alta rentabilidad. Para la explotación de estos recursos, se recurrió a la delimitación jurídica a objeto de establecer el derecho que cada Estado posee en la zona, sin embargo, los espacios respectivos que cada país ha adquirido en virtud de dicha delimitación podrían verse afectados por la sedimentación deltaica, en los aspectos social, económico, político y limítrofe, tal y como se concluye en este artículo.

  5. The Crustal Structure and Seismicity of Eastern Venezuela

    Science.gov (United States)

    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.

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

    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.

    The frequency of American visceral leishmaniasis affecting humans on Margarita Island, Venezuela, has increased in recent years, and infected dogs appear to constitute the principal source of infection. ELISA tests with Leishmania donovani promastigotes and rK39 antigen from L. chagasi in serum from 541 dogs were positive in 33.1% and 21.6% of the samples, respectively. A second blood sample taken from 50 animals after 8-10 months revealed an increase from 24% to 40% of ELISA positivity to both antigens, suggesting high susceptibility and transmission in the canine population. Among 42 serologically positive dogs, 33% of which showed clinical signs of disease, 79% were positive in polymerase chain reactions using primers specific for the L. donovani complex. Control measures including epidemiological hypersurveillance, the humane sacrifice of infected dogs, and rapid diagnosis and treatment of human cases have been initiated. PMID:11132371

  3. Gamma environmental dosimetry and radon concentration in Venezuela

    International Nuclear Information System (INIS)

    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/m3 ; 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

  4. Evaluation of Venezuela's Orinoco bitumen as an MHD fuel

    International Nuclear Information System (INIS)

    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

  5. Radon concentrations in hot spring waters in northern Venezuela

    International Nuclear Information System (INIS)

    Concentrations of 222Rn were determined in selected thermal water samples of the northern region of Venezuela. Concentrations in the range of 1-560 Bq/l were found. Soil radon concentrations and air radon concentrations related to the high values of radon concentration in water were investigated in El Castano and at a spa in Las Trincheras. An outstandingly high radon efflux was found in Las Trincheras with an average soil radon concentration of 122 kBq/m3, and an air radon concentration of 54 kBq/m3 in inhalation treatment pipes. Dose calculations revealed that regular consumption of the measured water samples presents an extra dose of radiation that may range up to 4 mSv/y

    1998-12-31

    The coal seams uplifted by the Perija and Sierra Nevada de Santa marta Mountains along the border of Colombia and Venezuela are high quality reserves with low mining ratios that are in close proximity to the coast. Since the late 70`s and early 80`s, various mining developments have increased the production of these reserves to its current level of 37 million tons per year. Most of the production is shipped to European and to North and South American markets. Further exploitation of these reserves will require significant investments in mine development, inland transportation, and port facilities. This paper will summarize the current status of the Colombian and Venezuelan coal industry, as well as the potential and challenges for increased production and exportation.

The chorionic sculpturing of L. migonei, L. ovallesi, L. absonodonta and L. gomezi was characterized by series of columns arranged in palisade to form sinuous ridges. In inter-ridge areas, the basal layer was covered with fibrous material. The outer chorion of L. panamensis had a pattern known as "mountain- or volcano-like". The morphology of the posterior pole and aeropyle had a common structure in the five species, with some species-specific characters. The eggshell features of the five species are compared with those of other phlebotomine sand flies.

    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).

    Full Text Available Over a two year period, the incidence of hepatitis C virus (HCV infection was evaluated in 29 hemodialysis patients, aged between 15 and 75 years (mean ± SD: 45 ± 39.5 years, from the University Hospital Hemodyalisis Unit, Maracaibo, Zulia State, Venezuela. Anti-HCV antibodies were determined using a fourth generation ELISA (Innotest HCV Ab IV kit and positive blood samples were tested using a recombinant assay kit (Inno-LIA HCV Ab III, both kits from Innogenetics N.V., Belgium. The findings indicate a lack of HCV seroconversion in the hemodialysis patients over the study period, confirmed by the recombinant assay. Risk factors for HCV infection were 0.3270 (95% confidence interval: 0.01323-8.080 in patients undergoing hemodialysis. The findings suggest a lack of significant sources for HCV infection due to the preventive measures to avoid its transmission in the hemodialysis unit.

    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.

  14. Surname frequency and the isonymy structure of Venezuela.

    2000-05-01

    Isonymy in Venezuela was studied analyzing the surnames of 3.9 million adults 40 years and older, selected from the register of electors updated in 1991. The electors were not differentiated by sex and represented all 22 states of Venezuela and its Federal District. The states of Nueva Esparta, an island, and Mérida, in the Venezuelan Andes, have the highest coefficients of microdifferentiation (R(ST)) and of inbreeding due to random isonymy. The states of Miranda, Aragua, Carabobo, and the Federal District, which includes the capital, Caracas, or are very close to it, had the lowest R(ST) values. The weighted averages of Fisher's alpha, a measure of surname abundance, varied by state from 43 in Nueva Esparta to 226 in Miranda, with a value of 210 for the entire country, much smaller than those observed in Switzerland, Germany, or Italy (2,396, 2,855, and 5,855, respectively). The fact that 32% of the total Venezuelan sample has only 40 surnames easily accounts for this small alpha. The correlation between the Euclidean distance and the log of geographic distance between the capital cities of states in km is high and significant (r = 0.78). The dendrogram built with the Euclidean distance matrix indicates the presence of three main clusters. One is formed by 10 states located in the western-central part of the country. The states of Zulia and Falcón join this cluster at a distance of 0.54 Euclidean units. A second cluster is formed by Barinas and the three Andean states. After combining these two, a third cluster joins them, formed by six Eastern states. Finally, the state of Amazonas enters the dendrogram at a distance of 0.66 units. Am. J. Hum.

    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.

    2009-04-01

    Paleoseismic studies have proved to be a powerful tool in seismic hazards assessment by he contributing to asses the seismogenic potential of a given fault by expanding the time window o seismic activity beyond the limits of historical and instrumental seismicity. Trenching has been an essential tool for paleoseismic studies in Venezuela. The first paleoseismic trenching project in Venezuela goes back to 1968 when Compania Shell de Venezuela retained the services of Woodward Clyde and Associates,(WCA), USA to asses the seismic integrity of the earthen dikes of Costa Oriental of Lake Maracaibo Protection System (COLM) in western Venezuela. The study was carried out under the general coordination of this author. An important part of this project included a seismology and seismic geology study under the direction of Geologist L.S. Cluff. This was the first ever study undertaken in Venezuela and included two excavations across the Oca Fault north of the city of Maracaibo. After several years of inactivity, FUNVISIS (The Venezuelan Foundation for Seismological Research) carried out in 1980 a seismic hazard (SHA) for the Uribante Caparo Hydroelectric Project southwest Venezuela. In 1989, MARAVEN, an operating company of PETROLE0S DE VENEUELA S.A. (PDVSA) undertook the project of a products pipeline form Maracaibo to El Vigia, south of Lake Maracaibo. Again, FUNVISIS was contracted to carry out a SHA, which included the digging of 5 trenches, which were supplemented with five more trenches for the COLM project. Trenching activity contined in Venezuela in the framework of SHA project, under the direction of Dr. Audemard. In 2001 Venezuelan trenching experience was exported to the neighboring Colombia as e Dr. Audemard t undertook a palaoseismicity project which included the digging of five trenches. In conclusion, paleoseismicty studies have given us the possibility of extending the scope of both instrumental and historical seismicity by some 10,000 years, trenching has

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

    Data from the 1977 Venezuela Fertility survey were used to assess recent trends in fertility and to attempt an understanding of future fertility based on observed trends. Between 1951-61, the total fertility rate increased from 5.96 to 6.61. In the 1960s, the fertility of women aged 15-30 years declined somewhat and the use of contraception and sterilization became more widespread, so that by 1971 the total fertility rate fell to 5.58. It is possible that the 1977 fertility survey slightly underrepresented women in the Caracas area, which would tend to overestimate fertility at the national level. The small sample size of 4361 women aged 15-44 involved considerable fluctuations in fertility rates from year to year. The risk of errors resulting from the method of retrospective reporting of live births appeared to be small since the recall period was relatively short. A series of quinquennial rates for women aged 15-39 was constructed for each age group from 1968-77. Fertility rates estimated for 1971 and 1976 respectively from the Venezuela Fertility Survey results using a moving average for 3 years were 120.7 and 105.1 for women 15-19, 259.0 and 225.1 for women 20-24, 255.0 and 213.1 for women 25-29, 214.3 and 167.7 for women 30-34, and 150.0 and 103.6 for women 35-39. The results were quite close to fertility rates estimated in other sources. The 1977 fertility survey indicated a trend toward later age at marriage and a correlation of ideal family size with age. The ideal number of children was 4.2 for the total sample, 5 children for women aged 35-39 years, 4.5 for those aged 30-34, 3.9 for those 25-29, and 3.5 for those aged 20-24. 55% of women in union stated they wanted no more children. 46% of women exposed to risk of pregnancy used a modern method of contraception; the proportion varied from 40% of those with 1 child to 56% with 4 children. The fertility decline, reduced ideal family size, and use of modern contraception were closely associated with

  11. Gamma radioactivity in sediments of Maracaibo Lake, Venezuela

    International Nuclear Information System (INIS)

    Maracaibo Lake is located to the west part of Venezuela (see Figure), with a surface of 13.000 Km2, its coast embraces a longitude of 729 Km. This lake is the largest fresh water hydrologic basin of Venezuela and its ecosystem is subjected to intense and constant modification due to the strong oil exploitation developed in this region. Both in the coastal area and inside the lake, the petroleum extraction process induces modification in the ecosystem. Radioactive content characterization was carried out in coastal sediments of Maracaibo Lake, measuring the specific activity of the following elements: 40K, gamma emitters of the natural radioactive series (238U and 232Th) and radioactive elements of anthropogenic origin (137Cs, among others) and cosmogenic as Berilium-7. The radioactive disequilibrium in the 238U and 232Th series was evaluated. Surface samples (from depth up to 5 cm) of the sediments along the coast were recollected and measured by high resolution gamma spectroscopy using a HpGe detector of approximately 2 KeV resolution for the 1,33 MeV 60Co peak and efficiency higher than 20% (supplied under the IAEA Technical Co-operation Project VEN/9/005). The 137Cs concentrations ranged in the interval 0,5-13,1 Bq/kg, while those of natural radionuclides are 238U (2,12 - 5,01 ppm), 232Th (6,71-38,58 ppm) and 40K (1,05-3,64%), assuming radioactive equilibrium in samples. Between elements of the 238U series high correlation was obtained while it is low between those of the 232Th series, being evidenced radioactive disequilibrium in this series. We found high positive correlation between 40K and elements of the 232Th series, and in turn low and negative with those of the 238U series. 232Th and 238U correlate negatively one to each other. This coastal sediment characterization of Maracaibo Lake allowed us to obtain a map of radioactive levels in these areas, which will serve as reference for future investigations.

    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

    Live-cell imaging of biological processes at the single cell level has been instrumental to our current understanding of the subcellular organization of bacterial cells. However, the application of time-lapse microscopy to study the cell biological processes underpinning development in the sporulating filamentous bacteria Streptomyces has been hampered by technical difficulties. Here we present a protocol to overcome these limitations by growing the new model species, Streptomyces venezuelae, in a commercially available microfluidic device which is connected to an inverted fluorescence widefield microscope. Unlike the classical model species, Streptomyces coelicolor, S. venezuelae sporulates in liquid, allowing the application of microfluidic growth chambers to cultivate and microscopically monitor the cellular development and differentiation of S. venezuelae over long time periods. In addition to monitoring morphological changes, the spatio-temporal distribution of fluorescently labeled target proteins can also be visualized by time-lapse microscopy. Moreover, the microfluidic platform offers the experimental flexibility to exchange the culture medium, which is used in the detailed protocol to stimulate sporulation of S. venezuelae in the microfluidic chamber. Images of the entire S. venezuelae life cycle are acquired at specific intervals and processed in the open-source software Fiji to produce movies of the recorded time-series. PMID:26967231

    Overweight and obesity are a public health problem worldwide affecting adults and children as well. The aim of this study was to assess overweight, lipid profile and cardiovascular risk ratios in 390 preschool children from low socio-economic level from Valencia, Venezuela. Nutritional anthropometric evaluation measured by body dimensions, and serum determination of cholesterol, triglycerides, HDL-cholesterol, LDL-cholesterol and cardiovascular risk factors, were determined. 95% of the children were in relative and critical poverty. 14.3% of undernutrition and 20.8% of overweight was found. Lipid profile was in normal range, with no significant differences by sex, but higher values for HDL-cholesterol and risk ratios were found in children aged 1 to 3.99 years. Even though no differences were found by nutritional status, overweight children had higher values for lipids, except HDL-cholesterol. 6.3% of overweight children had cholesterol > or =170 mg/dL, 16.5% LDL-cholesterol > or =110 mg/dL, 40.5% triglycerides > or =75mg/dL and 100% HDL-cholesterol Nutritional and educational intervention should be addressed.

  20. Geochemical record of anthropogenic impacts on Lake Valencia, Venezuela

    International Nuclear Information System (INIS)

    Bulk geochemical parameters and organic matter biomarkers in a short, high resolution gravity core (Lake Valencia, Venezuela) were examined to reconstruct anthropogenic impacts on the lake's conditions. During the period of ca. 1840-1990, sedimentary organic matter was characterized by high contents of total organic C (TOC) and total N (TN), low TOC/TN values as well as relatively enriched δ13C and δ15N signals, suggesting a primary autochthonous (algae and macrophytes) organic matter origin. The occurrence of large amounts of C23 and C25 relative to C29 and C31n-alkanes indicated substantial inputs from submerged/floating macrophytes. The variations of C32 15-keto-ol, tetrahymanol, diploptene, C32 bishomohopanol, 2-methylhopane, dinosterol and isoarborinol concentrations over the investigated period record changes in the planktonic community structure, including Botryococcus braunii, bacteriavore ciliates, cyanobacteria, Eustigmatophytes and dinoflagellates. A principal shift occurred in the 1910s when cyanobacteria and dinoflagellates became more abundant at the expense and decline of B. braunii and Eustigmatophytes, likely related to increasing anthropogenic activity around the lake. A second shift (less obvious) occurred in the 1960s when cyanobacteria became the sole predominant planktonic class, coinciding with further deterioration of lake conditions

  4. Anatomy of 31 species from Mimosoideae (Leguminosae) subfamily on Venezuela

    International Nuclear Information System (INIS)

    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.

    Chemical, paleontological, and mineralogical analyses of a 7.5-meter core from the middle of Lake Valencia, Venezuela, have provided information on the paleoclimatic history of this low-elevation, low-latitude site for the last 13,000 years. The data show that dry climates existed in this region from 13,000 years before present (B.P.) until about 10,000 years B.P. The Lake Valencia Basin was occupied by intermittent saline marshes at that time. About 10,000 years B.P., a permanent lake of fluctuating salinity formed and arboreal plant communities replaced the earlier dominant xeric herbaceous vegetation and marsh plants. By 8500 years B.P., Lake Valencia reached moderate to low salinities and discharged water; the modern vegetation became established at that time. After 8500 years B.P., the lake twice ceased discharging as a result of reduced watershed moisture. The second of these drying episodes is still in progress and has been aggravated by human activities in the watershed. Copyright ?? 1981 AAAS.

    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.

    Yardlong bean (Vigna unguiculata subsp. sesquipedalis) plants with virus-like systemic mottling and leaf distortion were observed in both experimental and commercial fields in Aragua State, Venezuela. Symptomatic leaves were shown to contain carlavirus-like particles. RT-PCR analysis with carlavirus-specific primers was positive in all tested samples. Nucleotide sequences of the obtained amplicons showed 84%-74% similarity to corresponding sequences of Cowpea mild mottle virus (CPMMV) isolates deposited in the GenBank database. This is the first report of CPMMV in Venezuela and is thought to be the first report of CPMMV infecting yardlong bean.

  1. 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

    Merida Andes (MA) is one of the most important orogenic belt in Venezuela and represents the northern culmination of South America Andes. During the last 60 years, several models have been proposed to explain the shallow and deep structure, using different geological, geophysical, seismological, geochemical and petrologic concepts; nevertheless, most of them have applied local observation windows, and do not represent the major structure of MA. Therefore, a multidisciplinary research group, coordinated by FUNVISIS, in close cooperation with UCV, ULA and PDVSA, is proposed in order to get the outlined goals in the project entitled GIAME ("Geociencia Integral de los Andes de MErida") was established, which aims to generate a lithospheric scale model and the development of a temporal dynamic model for the MA. As a base for lithospheric investigations of the Merida Andes, we are proposing three wide angle seismic profiles across the orogen on three representative sites, in order to determine the inner structure and its relation with the orogen's gravimetric root. To the date, there are no seismic studies at lithospheric scale which cross MA. The wide angle seismic will be complemented with the re-processing and re-interpretation of existing reflection seismic data, which will allow to establish a relationship between MA and its associated flexural basins (Maracaibo and Barinas-Apure basins). Depending on the results of the VENCORP Project (VENezuelan COntinental Reflection Profiling), which might show some reliable results about crustal features and Moho reflectors along three long seismic profiles at Caribbean Moutain system, a reflection seismic profile across the central portion of MA is proposed. Additional tasks, consisting in MA quaternary deformation studies, using research methods like neotectonics and paleoseismology, georadar, numerical modeling, cinematic GPS, SAR interferometry, thermocronology, detailed studies on regional geology, flexural modeling

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

  6. Neogene history of the Carapita Formation, Eastern Venezuela basin

    Sanchez Zambrano, Dennis Alberto

    The planktonic and benthic foraminifera from the lower to middle Miocene shales of the Carapita Formation of Eastern Venezuela in three exploration wells and one outcrop section are analyzed with the objectives of establishing a precise biostratigraphy of the formation and its bathymetric history. Comparison with the well-preserved microfaunas of the correlative Cipero Formation of Trinidad made possible the achievement of these objectives. The formation, up to 4500 to 6000 m thick in outcrops, extends from northeastern Anzoategui and North of Monagas States to the Gulf of Paria and is both an important oil reservoir towards the east and the main seal rock for the Oligocene reservoir in the north of Monagas State. In the area studied the Carapita Formation spans lower to lower middle Miocene Zones N6/M3 to N9/M6; its upper part is unconstrained as only rare long ranging early Miocene to early Pliocene planktonic foraminifera occur above the Orbulina datum. Unexpectedly, we found that the four lower to middle Miocene sections are highly discontinuous, with hiastuses as long as 4 Myr. Based on the abundance patterns of sixty-nine species of benthic foraminifera and analysis of morphotype abundance following the methodology of Corliss and Chen (1988) and Corliss and Fois (1993), we show that the Carapita Formation was deposited at outer neritic to middle bathyal depths (≥200--1000 m), whereas the Cipero Formation was deposited at middle to lower bathyal depths (≥600--2000 m). Importantly, the bathymetric changes are associated with unconformities in all sections, strongly suggesting that both (shallowing and associated unconformities) were tectonically induced.

    In the School of Science of the Universidad de Los Andes (ULA), in Mérida, Venezuela, a very successful event focused on high school students and primary school students, was founded in 2000. The name of this event is "Encounters with Physics, Chemistry, Mathematics, and Biology" (hereinafter "Encounters with Science"), and it integrates these disciplines as well as Astronomy. Its main purpose is that young minds can become familiar with the methods of science inquiry and reasoning, and can understand the concepts and processes of the sciences through thoroughly prepared experiences. This flourishing program is continuing to grow and to become strong. As a matter of fact, in its sixth edition (2005), the number of high and elementary school students coming from all over the country, has reached the outstanding number of nine thousand. Among all the experiences that the students could be engaged in were many involving Astronomy. These experiences were prepared by professors, together with graduate and undergraduate students, who are pursuing their degrees in all branches of science including astronomy. Although there is this incredible team of faculties and graduate and undergraduate students working together; the target is the students of the high and elementary schools. We certainly focus on the engaging and encouraging of students to experience scientific work first hand. Additionally, our professors have prepared an excellent didactic material that can, together with the hour/class teaching, prepare high school and elementary school students for a better understanding of science; particularly, helping in this way for a better education in Astronomy. The main event of the Encounters lasts five days in the School of Science of ULA, but subsidiary events are spread all over the year and around the country. As a successful program, it can be interesting to see if other countries can adopt this method to recruit or to trigger the interest of students to pursue their

  8. Niche conservatism of Eulophia alta, a trans-Atlantic orchid species

    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.

    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.

  2. Adapting EVIAVE methodology as a planning and decision-making tool in Venezuela

    International Nuclear Information System (INIS)

    Landfills in Venezuela have serious problems regarding their location, design and operation. In fact, basic waste disposal is one of the main weaknesses of the municipal waste management in this country. The Venezuelan Ministry of Environment and Renewable Resources has studied and identified the negative impacts of operating landfills, but no program has been implemented to determine the cause-effect relation of these impacts or to design strategies to counteract with the serious environmental and health risks generated. This paper describes how EVIAVE methodology can be successfully used for landfill diagnosis, and shows how this type of landfill diagnosis was applied in Venezuela. For our research study, we carried out both a quantitative and qualitative evaluation of the environmental problems generated by 22 landfills in Venezuela. Our study was based on the following environmental indexes: Landfill Environment, Environmental Risk, Environmental Value, and Probability of Contamination. For the purposes of our study, it was first necessary to adapt EVIAVE to the legal system and social context in Venezuela. The results obtained confirmed the applicability of this methodology to Venezuelan landfills. EVIAVE was found to be an effective planning tool that provided crucial information for the development of action plans, which would improve landfill operation, and help make decisions pertaining to their closure, sealing and eventual recovery.

    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

    Full Text Available The regimes of Hugo Chávez, Evo Morales, and Rafael Correa undermine contestation while simultaneously increasing the material inclusion of the poor and the excluded. These regimes that are usually lumped together show distinct patterns in fostering participation. Whereas in Ecuador participation is reduced to voting in elections, participatory institutions were created in Venezuela and Bolivia. And whereas mobilization in Bolivia comes mostly from the bottom up, in Venezuela and Ecuador it comes from the top-down. To compare their divergent patterns this paper analyses: 1 the strength of subaltern organizations when these leaders were elected; 2 the confrontation between governments and the oppositions; and 3 the views of democratization of the coalitions that brought these regimes to power.Resumen: En nombre del pueblo: democratización, organizaciones populares y populismo en Venezuela, Bolivia y EcuadorLos regímenes de Hugo Chávez, Evo Morales y Rafael Correa atentan en contra del pluralismo a la vez que incluyen materialmente a los pobres y a los excluidos. Estos regímenes que por lo general son aglutinados en un mismo saco tienen diferentes patrones para promover la participación política. Es así que mientras que en Ecuador la participación se reduce a votar en elecciones, en Venezuela y Bolivia se crearon instituciones participativas. Mientras que en Bolivia la participación viene en gran medida desde las bases, en Ecuador y Venezuela viene desde arriba hacia abajo. Para comparar los diferentes patrones este trabajo estudia: 1 la fuerza de organizaciones de los subalternos cuando estos líderes fueron electos; 2 la confrontación entre el gobierno y las oposiciones; 3 las visiones sobre democratización de las coaliciones que llevaron al poder a estos líderes.

    Directory of Open Access Journals (Sweden)

    Roberto Briceño-León

    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

During its first five years of existence, Barrio Adentro has improved access and utilization of health services by reaching approximately 17 million impoverished and middle-class citizens all over Venezuela. This was achieved in approximately two years and provides an example of an immense "South-South" cooperation and participatory democracy in health care. Popular participation was achieved with the Comités de Salud (health committees) and more recently with the Consejos Comunales (community councils), while mostly Cuban physicians provided medical care. Examination of a few epidemiological indicators for the years 2004 and 2005 of Barrio Adentro reveals the positive impact of this health care program, in particular its primary care component, Barrio Adentro I. Continued political commitment and realistic evaluations are needed to sustain and improve Barrio Adentro, especially its primary care services. PMID:19326784

    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.

It is assigned to Rowlandius tentatively, because some characters are not congruent with this genus, nevertheless the absence of synapomorphic characters limits its inclusion in other one. This is the first record of the genus from Venezuela, and the third South American species described.

Crises stemming from both macroeconomic and bank-specific causes had the largest macroeconomic impact. Countries with high dollarization and a large share of foreign and government-owned banks maintained a more stable deposit base, at least temporarily, by shi...

  7. 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.

  8. [Direct genetic manipulation and criminal code in Venezuela: absolute criminal law void?].

    Science.gov (United States)

    Cermeño Zambrano, Fernando G De J

    2002-01-01

    The judicial regulation of genetic biotechnology applied to the human genome is of big relevance currently in Venezuela due to the drafting of an innovative bioethical law in the country's parliament. This article will highlight the constitutional normative of Venezuela's 1999 Constitution regarding this subject, as it establishes the framework from which this matter will be legally regulated. The approach this article makes towards the genetic biotechnology applied to the human genome is made taking into account the Venezuelan penal law and by highlighting the violent genetic manipulations that have criminal relevance. The genetic biotechnology applied to the human genome has another important relevance as a consequence of the reformulation of the Venezuelan Penal Code discussed by the country's National Assembly. Therefore, a concise study of the country's penal code will be made in this article to better understand what judicial-penal properties have been protected by the Venezuelan penal legislation. This last step will enable us to identify the penal tools Venezuela counts on to face direct genetic manipulations. We will equally indicate the existing punitive loophole and that should be covered by the penal legislator. In conclusion, this essay concerns criminal policy, referred to the direct genetic manipulations on the human genome that haven't been typified in Venezuelan law, thus discovering a genetic biotechnology paradise.

    Rodríguez Larralde, A; Casique, J

    1993-01-01

    The genetic structure of the State of Aragua, Venezuela, has been studied through the analysis of surnames obtained from the register of electors. The analysis covered 23 counties and included a total of 99,593 individuals and 6,338 different surnames. Estimators of isolation, consanguinity, microdifferentiation and four measures of genetic distance, were studied. When our results were compared with those obtained in other States of Venezuela studied previously (Falcón, Lara, Mérida, Nueva Esparta and Yaracuy), Aragua appears as the State most open to new migrants, probably due to its nearness to Caracas, Venezuela's capital city. Within Aragua, the counties most isolated are Choronií, Ocumare de la Costa and Tovar, while those less isolated are El Limón, Turmero, La Victoria, San Mateo and Cagua. The correlations between the logarithmic transformations of genetic and geographic distances were all significant, revealing surname differentiation by distance. The dendrogram built with the Euclidean distance matrix shows a first group of counties formed by those localized towards the central portion of the State, to which southern counties are added. Choroní and Ocumare de la Costa form a group which enters the dendrogram just before Tovar, the last county to be included in the analysis. Seven surnames with a focal distribution within the State were identified: Ayala and Calanche in Choroní; Kanzler, Misle and Ruh in Tovar; Lira in San Mateo and Santaella in Barbacoas. PMID:7483965

    The results of a five year program (1988-90-91-92-93) on quality assurance and dose calibration for 12 Cobalt-60 units from public hospitals, which represents 30% of total radiation therapy units in Venezuela, are presented. The remarkable improvement in the general performance of these units can be seen in the IAEA/WHO Postal TLD Intercomparison results which gave 100% within ± 5% in 1990 and 1992, while 63% in 1990 and 44% in 1992, with errors up to 37% were obtained for the participants not included in the program. The difference between the two groups lead the government to decrete through the Gaceta Oficial de la Republica de Venezuela, Resolution G-1397 on March 3, 1993, the quality assurance and dose calibration programs shall be established for all radiation therapy installations in Venezuela. The project for the standards was developed by the SSDL physicists and it was already approbated by the Health Ministry. It is expected that the Norms will enter into effect by the end of 1994.

    The Caribbean (CAR)-South American (SA) plate boundary in Venezuela is a broad zone of faulting and diffuse deformation. GPS measurements show the CAR moving approximately 2 cm/yr relative to SA, parallel to the strike slip fault system in the east, with more oblique convergence in the west (Weber et al., 2001) causing the southern edge of the Caribbean to subduct beneath northwestern South America. The west is further complicated by the motion of the triangular Maracaibo block, which is escaping northeastward relative to SA along the Bocono and Santa Marta Faults. In central and eastern Venezuela, plate motion is accommodated by transpression and transtension along the right lateral San Sebastian- El Pilar strike-slip fault system. The strike-slip system marks the northern edge of coastal thrust belts and their associated foreland basins. The Archean-Proterozoic Guayana Shield, part of the Amazonian Craton, underlies southeastern and south-central Venezuela. We used the 87 station Venezuela-U.S. BOLIVAR array (Levander et al., 2006) to investigate lithospheric structure in northern South America. We combined finite-frequency Rayleigh wave tomography with Ps and Sp receiver functions to determine lithosphere-asthenosphere boundary (LAB) depth. We measured Rayleigh phase velocities from 45 earthquakes in the period band 20-100s. The phase velocities were inverted for 1D shear velocity structure on a 0.5 by 0.5 degree grid. Crustal thickness for the starting model was determined from active seismic experiments and receiver function analysis. The resulting 3D shear velocity model was then used to determine the depth of the LAB, and to CCP stack Ps and Sp receiver functions from ~45 earthquakes. The receiver functions were calculated in several frequency bands using iterative deconvolution and inverse filtering. Lithospheric thickness varies by more a factor of 2.5 across Venezuela. We can divide the lithosphere into several distinct provinces, with LAB depth

    1992-10-01

    This document presents the final report of a study of residential energy use in Caracas, the capital of Venezuela. It contains the findings of a household energy-use survey held in Caracas in 1988 and examines options for introducing energy conservation measures in the Venezuelan residential sector. Oil exports form the backbone of the Venezuelan economy. Improving energy efficiency in Venezuela will help free domestic oil resources that can be sold to the rest of the world. Energy conservation will also contribute to a faster recovery of the economy by reducing the need for major investments in new energy facilities, allowing the Venezuelan government to direct its financial investments towards other areas of development. Local environmental benefits will constitute an important additional by-product of implementing energy-efficiency policies in Venezuela. Caracas`s residential sector shows great potential for energy conservation. The sector is characterized by high saturation levels of major appliances, inefficiency of appliances available in the market, and by careless patterns of energy use. Household energy use per capita average 6.5 GJ/per year which is higher than most cities in developing countries; most of this energy is used for cooking. Electricity accounts for 41% of all energy use, while LPG and natural gas constitute the remainder. Specific options for inducing energy conservation and energy efficiency in Caracas`s residential sector include energy-pricing policies, fuel switching, particularly from electricity to gas, improving the energy performance of new appliances and customer information. To ensure the accomplishment of an energy-efficiency strategy, a concerted effort by energy users, manufacturers, utility companies, government agencies, and research institutions will be needed.

El artículo, dividido en cuatro secciones, es una síntesis de la historia del derecho de propiedad del subsuelo, de las compañías petroleras, del Estado y de la renta petrolera internacional en Venezuela desde 1920 hasta el presente. ABSTRACT: This paper shows that in almost a century of history of the Venezuelan oil industry (1917-2009, International Oil Companies (IOCs have been doing business in this country for just more than fourth fifth of this period (74/92 years. It shows too that during that time, what has been changing in this country for the oil companies, IOCs or National Oil Companies (NOCs, is the way of doing business in the upstream of the oil industry: the terms and conditions of the owner of the underground property rights. Terms and conditions mean in this context how much of the oil generated rents in the underground public and national property rights goes to the pockets of the oil companies and government. This paper summarizes the history of the underground property rights, oil companies, the State, and rent in Venezuela from 1920 up to the present.

    As part of its spray system of power generation, TransAlta operates the Rundle power canal, forebay and powerhouse located near Canmore, Alberta. Two penstocks run from the Rundle forebay to the powerhouse. Ongoing seepage problems around the intake to Unit No. 2 have been a problem for TransAlta, causing recurrent sinkholes, unpredictable variations in piezometric levels within the dam, and seepage flows at its toe. In order to assess the cause of the seepage and make a decision to proceed with mitigation, TransAlta conducted more frequent monitoring of these parameters, several surveys along the dam, and monitoring of pore water temperatures. The mitigation involved construction of a grout curtain under and adjacent to the intake and was performed from the ground surface as well as from within the penstock. This work required shutting down the penstock to Unit No. 2, lowering the water level in the forebay, and de-rating flow to Unit No. 1. This paper presented a brief history of the facility contributing to the cause of the seepage and the monitoring undertaken to assess its extent and seriousness. It also discussed the design and progress of the grouting program, including the response of the geotechnical instrumentation to the drilling and grouting process. Last, in order to evaluate the effectiveness of the remedial work, the post-grouting monitoring was examined. Comments were made on the usefulness of the various monitoring instruments and techniques used to determine dam performance prior to, during and after the grouting work. 1 ref., 9 figs.

    Full Text Available BACKGROUND: 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. METHODOLOGY/PRINCIPAL FINDINGS: 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. CONCLUSIONS/SIGNIFICANCE: 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

    Full Text Available La autorregulación de las comunicaciones comerciales constituye una práctica relativamente reciente. Numerosas empresas, en la actualidad, con buen criterio, están adecuando sus actividades publicitarias a los instrumentos derivados de la autorregulación. Estos últimos, fomentados en ciertas ocasiones por el sector público, constituyen un sugerente complemento de la normativa legal. En el presente estudio, nos referiremos, con carácter general, de forma somera, a esta figura. Posteriormente, tomaremos conciencia de la misma en el caso de Venezuela.

    Background 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. Methodology/Principal Findings 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. Conclusions/Significance 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

    International Nuclear Information System (INIS)

    This study is the first report made in Venezuela concerning the ultrastructural characteristics of Ehrlich ia sp in mononuclear blood cells from an experimentally infected dog. The animal developed clinical manifestations characteristic of the infection, and typical intracytoplasmic inclusion bodies were clearly seen in blood smears stained with modified Giemsa examined by light microscopy. Microorganisms were visualized by transmission electron microscopy. The cytoplasmic inclusions, consisted of membrane-lined vacuole-containing elementary bodies. The organisms were extremely pleomorphic. Elementary bodies were surrounded by two distinct membranes and each was constituted by electro-dense granules. These findings corresponded to the described electron microscopy morphology which characterizes the Ehrlich ia genus

    Full Text Available RESUMEN: El mundo ha avanzado hacia la globalización, lo que exige que América Latina, con poca relevancia internacional y con una situación económica crítica, busque ajustarse a las nuevas exigencias internacionales mediante "la desregulación y la coordinación económica". También se hace prioritaria la búsqueda de la integración regional tanto a nivel público como privado a través de instituciones como Mercosur y la Comunidad Andina de Naciones.Este artículo plantea las incidencias de la globalización y la integración en la política exterior venezolana y los mecanismos a aplicar para ajustarse al nuevo modelo mundial. Tres son los puntos prioritarios en este sentido: los cambios globales, el petróleo y la política exterior.La situación de Venezuela como país proveedor de petróleo a Estados Unidos le ha permitido ser conservador en sus posiciones y asumir la apertura económica de forma más discreta al resto de países de la región. La democracia es otro tema que rodea las relaciones internacionales, especialmente lo relativo a los derechos humanos y al buen gobierno, y del cual Venezuela se beneficia al procurar un espacio idóneo para su desarrollo.ABSTRACT: The world has moved towards globalization, which means that Latin America, that has low international leverage and a critical economic situation, has to search for an adjustment to the new international demands by means of "deregulation and economic coordination". It is also a priority to pursue the regional integration at the prívate and public levels through institutions such as Mercosur y la Comunidad Andina de Naciones.This article poses the incidences of globalization and integration in the Venezuelan international policy, as wcll as the mechanisms of adjustment to the new world orden.

    Full Text Available Este artigo apresenta uma compreensão sobre o autocuidado do cuidador familiar segundo a teoria de Dorothea Orem. Resulta de uma pesquisa qualitativa com aporte da Teoria Fundamentada nos Dados, utilizando-se das técnicas de visita domiciliar, registro de notas de campo e entrevista semiestruturada com 11 cuidadores, após a internação de familiar em um Hospital Universitário de Minas Gerais. Foram obtidas quatro categorias, destacando uma categoria central, em torno da qual se analisaram as facilidades, dificuldades e estratégias para o autocuidado do cuidador. Entre as dificuldades, foram evidenciadas: tempo insuficiente para os cuidados com a saúde e, entre as facilidades, o apoio de outros familiares. As principais estratégias foram: apoio na fé; revezamento nos cuidados e recursos na comunidade. Concluiu-se que orientações no momento da alta e o acompanhamento de enfermagem após a alta contribuem para o autocuidado do cuidador, atuando sobre suas dificuldades e estimulando suas potencialidades.

Lo studio preliminaredelle circolazioni mensili e stagionali nella troposfera, nella bassa emedia stratosfera e nell'alta stratosfera ha rivelato che esse sono in certomodo interdipendenti. Ciò è posto qualitativamente in evidenza, ad esempio,dalla corrispondenza dei cunei e delle saceature delle configurazionibariclie dell'alta stratosfera con le aree oceaniche e continentali dell'EmisferoNord. Considerandole correnti a getto come sintesi delle grandi perturbazionidell'alta troposfera atte ad influire sulla struttura e circolazionedell'alta stratosfera, le conclusioni precedenti mi hanno indotto a programmareuna classificazione della struttura e della circolazione osservate, suciascuna delle stazioni aerologiche Mediterranee, in relazione alla loro posizionerispetto alle correnti a getto, onde reperire sperimentalmente le formuleche consentano una logica estrapolazione delle osservazioni correnti ai livellidesiderati.

    Dominantly inherited ataxias (spinocerebellar ataxias, SCAs) are a genetically heterogeneous group of neurologic diseases characterized by progressive cerebellar and spinal tract degeneration with ataxia and other signs, common to all known subtypes. Several types are relatively frequent worldwide, but in several countries, one specific SCA may show a higher prevalence owing to founder phenomena. In Venezuela, genetic epidemiological features of SCAs have been assessed during the last 30 years; mutations in ATXN1 (SCA1), ATXN2 (SCA2), ATXN3 (SCA3), CACNA1A (SCA6), ATXN7 (SCA7), ATXN8 (SCA8), ATXN10 (SCA10), TBP (SCA17) and ATN1 (dentatorubral pallidoluysian atrophy, DRPLA) loci were searched among 115 independent families. SCA7 was the most frequent subtype (26.6%), followed by SCA3 (25.0%), SCA2 (21.9%), SCA1 (17.2%), SCA10 (4.7%) and DRPLA (3.1%); in 43% of the families, the subtype remained unidentified. SCA7 mutations displayed strong geographic aggregation in two independent founder foci, and SCA1 showed a very remote founder effect for a subset of families. SCA10 families were scattered across the country, but all had an identical in-phase haplotype carried also by Mexican, Brazilian and Sioux patients, supporting a very old common Amerindian origin. Prevalence for dominant SCAs in Venezuela was estimated as 1:25 000 nuclear families, provenances of which are either Caucasoid, African or Amerindian. PMID:26538302

    2015-06-01

    Full Text Available El propósito del presente trabajo está relacionado con la evaluación de los recursos energéticos de Venezuela y su posicionamiento estratégico mundial, referido principalmente a la producción y consumo de energía primaria y reservas. Así mismo se han evaluado los recursos energéticos renovables con la finalidad de identificar oportunidades para el desarrollo de la energía sostenible. Los resultados indican que Venezuela posee recursos fósiles para más de 130 años de explotación, lo cual lo convierte en una potencia energética relevante en el contexto mundial. La potencialidad aprovechable de las energías renovables duplicó la producción de recursos fósiles en 2011. En la actualidad, el aprovechamiento de estas fuentes es inferior al 2 % del total disponible, lo que deja abierto un amplio rango de posibilidades para la diversificación de la matriz energética nacional mediante tecnologías limpias o sostenibles

  19. A project: 'Radiological protection in radiology', IAEA - Universidad Central de Venezuela

    International Nuclear Information System (INIS)

    For several years a reference center of the UCV has been working on the project VEN/9/007 on dose reduction in diagnostic radiology sponsored by the IAEA. The dose and quality image was evaluated for different types of radiological study (conventional radiology, CT, mammography, interventional radiology) in different facilities at Caracas and others regions of the Venezuela. TL dosimeters were used to assess dose and reduction in dose. Based on the recommendations given by CEC documents on diagnostic quality criteria, a quality control program in radiological protection of patients and staff has been developed, for example: Pilot study by using TLD in personnel radiation monitoring. Comparative study between high and low kVp in chest. Evaluation and dose reduction in chest pediatric. Reduction of radiation dose in studies of billiards via Quality Image and reduction of the dose in studies of colon by enema. Radiation dose of staff in fluoroscopy procedures. Evaluation and dose reduction in dental radiography in public Institutions. A mammography accreditation program for Venezuela, applied to public hospitals. (author)

    Full Text Available The purpose of the study was to document studies in Venezuela about chemical pollutants in air and water (2006 to 2013 through a systematic review. It was a descriptive, cross-sectional documental review. Databases of the major universities in the country, government institutions and Non-Governmental Organizations were reviewed. From the twenty-seven articles selected, eight (29.6% investigated air pollution, 12 (44.4% water pollution and 7 (25.9%, studied environmental media. 90.9% of the research was conducted in the North area of the country. Main objects of the study were water quality (20.5%, metals/minerals and environmental phenomena including climate change (17.9% each and overall contamination (12.8%. The limited access to public environmental information, few environmental awareness campaigns and the lack of citizenship, put investigations in this area in a secondary level. Researchers must be stimulated with increased funding to study the environmental problems in the country, so that their results contribute to fostering “environmental education” at all levels and compliance with the existing legal framework. It is concluded that research on chemical contaminants in environmental media in Venezuela is scarce. The environmental situation in the country requires further research in the most affected areas, including the South area of the country where many polluting basic industries are located.
