    The high accuracy on inferrring of rocks properties, such as permeability ($k$), is a very useful study in the analysis of wells. This has led to development and use of empirical equations like Tixier, Timur, among others. In order to improve the inference of permeability we used a hybrid Neuro-Fuzzy System (NFS). The NFS allowed us to infer permeability of well, from data of porosity ($\\phi$) and water saturation ($Sw$). The work was performed with data from wells VCL-1021 (P21) and VCL-950 (P50), Block III, Maracaibo Lake, Venezuela. We evaluated the NFS equations ($k_{P50,i}(\\phi_i,Sw_i)$) with neighboring well data ($P21$), in order to verify the validity of the equations in the area. We have used ANFIS in MatLab.

    Full Text Available Acoupa weakfish, Cynoscion acoupa, in Lake Maracaibo is subject to intense commercial fishing by an artisanal fleet, and a recent decrease in fish size observed from landings is of concern. This fishery has not yet been modeled, and its assessment and the establishment of management practices to overcome the current overfished condition are urgently needed. To address this, we used recent and past empirical growth estimates to model relative yield-per-recruit under different lengths at first capture. Our results from relative yield-perrecruit analysis showed evidence that growth and recruitment overfishing occur under current fishing practices in Lake Maracaibo. Particular attention was given to fishing practices in El Tablazo Bay where young, small fish predominate in the commercial catches (mean total length=33.7cm, well below the length at first sexual maturity (~40cm TL for both sexes. As management strategies, we propose to set a mesh size limit at or above 8.89cm (3.5in, which will reduce fishing mortality of immature fish, increase yield-per-recruit, and will result in an increase of Acoupa weakfish recruitment for the long term in Lake Maracaibo.La curvina, Cynoscion acoupa, en el Lago de Maracaibo se encuentra sometida a una intensa actividad pesquera comercial. No obstante, antes de este estudio no se había examinado el potencial efecto de la sobrepesca a través del modelado. Utilizamos estimados empíricos de crecimiento actuales y pasados para modelar el rendimiento-por-recluta relativo bajo diferentes longitudes de primera captura. Presentamos evidencia a partir de resultados de rendimiento-por-recluta relativo que indica que existe sobrepesca por crecimiento y reclutamiento bajo las prácticas pesqueras actuales en el Lago de Maracaibo. Se puso particular atención a las pesquerías en la Bahía El Tablazo donde predominan peces jóvenes pequeños en las capturas (longitud total promedio=33.7cm, muy por debajo de la longitud de

    The experience gained through decades of applying vertical steam injection well technology in the heavy oil producing region of Lake Maracaibo in Venezuela was discussed. The oil from the Bachaquero-01 heavy oil reservoir has an API gravity of 12. Petroleum producers made an attempt to optimize production in 1996 by drilling wells with 1000 ft of horizontal section and then injecting steam. However, the initial production of 1000 BOPD dropped by 50 per cent within 4 months. A NODAL production system analysis calculation suggested that the best remedy would be to apply horizontal gravel packs to allow for more permeability compared to natural sand packs. Gravel packing of the horizontal thermal wells began in October 2000 during a drilling and completion campaign in which 18 wells were successfully gravel packed. The average production for 6 of the wells increased by 135 BOPD after 8 months compared to 9 nearby nongravel-packed horizontal wells, representing an 18 per cent higher production rate than the declining rate of the nongravel-packed wells. After one year, productivity increased by an average of 15 per cent with no sand production. Gravelpack operations were conducted at a pump rate of 2 to 3 bbl/min with a sand concentration of 0.5 to 0.7 pounds of proppant per gallon added. This maintained continuous fluid returns of 50 to 80 per cent. 18 refs., 2 tabs., 7 figs.

    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.

The production in this sector has become larger than the formal one. In act, in Maracaibo more than 60% of population is living in these types of suburbs. These people have resolved their housing need accordingly to their low income and outside of offer sector of formal production. This paper analyses the house from a physical point of view by studying the constructives components in relation to the socioeconomical aspects of the families and their direct participation in building and financing their house. Four stages of the physical consolidation of housing in suburbs were distinguish. This contribution as an analytic description of the physical situation of housing in studied areas, concluded giving some recommendations for the improvement of the informal process of housing production in Maracaibo.

  12. The Cogollo Group and the oceanic anoxic events 1a and 1b, Maracaibo basin, Venezuela

    Directory of Open Access Journals (Sweden)

    José Alejandro Méndez Dot

    Full Text Available ABSTRACTCarbonates of Cogollo Group (Apón, Lisure and Maraca formations constitute the broader calcareous platform system originated during Aptian and Albian of Cretaceous in north-western South America, Maracaibo Basin, Venezuela. On the shallow shelf, a variety of calcareous sedimentary facies were deposited during marine transgressive and regressive cycles. Some of them developed porosity and constitute important hydrocarbon reservoirs. Due to some major marine transgressions, from early Aptian, the anoxic environment and characteristic facies of a pelagic environment moved from the outer slope and basin to the shallow shelf, during specific time intervals, favouring the sedimentation of organic matter-rich facies, which correspond to the oceanic anoxic events (OAEs 1a and 1b. The source rock of Machiques Member (Apón Formation was deposited during early Aptian OAE 1a (~ 120 Ma. The source rock of Piché Member, located at the top of the Apón Formation, was deposited during late Aptian OAE 1b (~ 113 Ma. Finally, La Luna Formation, from Cenomanian, that covers the OAE 2 (~ 93 Ma, represents the most important source rock in the Maracaibo Basin. In this way and based on sedimentological and organic geochemistry results from the determinations performed on 247 samples belonging to six cores in the Maracaibo Basin, we propose these two organic-rich levels, deposited on the shallow shelf of the Cogollo Group, as "effective source rocks", additional to La Luna Formation, with oil migration in relatively small distances to the porosity facies.

    The presence of a microgastropod identified as Potamopyrgus sp. was detected previously in the Maracaibo System; nevertheless, a detailed morphological analysis identified this snail in other genera. The objective of this work is to update the distribution and taxonomy of Pyrgophorus platyrachis in the Maracaibo System, Venezuela in samples obtained between 2001 and 2009. The presence of hundreds of individuals of P. platyrachis were observed in the estuary, indeed in the localities of the Gran Eneal lagoon (4 111 snails), Peonías lagoon (229 snails), Punta Capitán Chico (758 snails), San Francisco (2 517 snails), Curarire (240 snails), Apon River mouth (173 snails), Ojeda City (240 snails), Bachaquero (128 snails) and Tomoporo de Agua (385 snails). We performed a taxonomical analysis, and emphasized in ecological aspects, such as the distribution of the species and habitat features, as near vegetation and type of associated sediment. We found three morphotypes of the species, one smooth, another with spiral striations and the other with spines. Smooth morphotype was exclusive of the Gran Eneal lagoon, Peonías lagoon, Punta Capitan Chico and Apon River mouth localities, whereas the other two morphotypes were found together in the remaining localities. According to our detailed anatomical and taxonomical analysis we propose a synonymy between P. platyrachis and the other species described like Pyrgophorus parvulus and Pyrgophorus spinosus.

    Four pairs of the poorly understood tropical mockingbird Mimus gilvus were captured and color banded at a grassland in Maracaibo, Venezuela in June 1997. Throughout the following 8 months, individuals were observed two days per week for 4 hours each. We recorded courtship behaviour, nest construction, incubation, parental care, territory defense and timing of reproductive cycle. Pairs lived in defined territories defended primarily by the male. Both sexes participated in nest building which began at the start of two rainy seasons: April and October. Between April and June, 80% of nests were parasited by the shiny cowbird (Molothrus bonariensis). No parasitism was recorded in the later nesting season. Consequently, breeding success for the April and October seasons was 20% and 83% respectively. Only the female incubated and the mean clutch size was 2.2 eggs.

    Microsporidioses are considered emerging and opportunistic infections in immunocompromised individuals worldwide. The purpose of this study was to identify the species of intestinal microsporidia in patients with HIV-AIDS from the Servicio Autónomo Hospital Universitario de Maracaibo, Venezuela (SAHUM). Fecal samples were collected from 50 patients with confirmed diagnosis of HIV, during the years 2007 and 2008; the CD4 values were obtained from 42 patients. The samples were analyzed by separate PCRs to identify Encephalitozoon intestinalis and Enterocytozoon bieneusi. Microsporidia species showed a 36% prevalence: ten patients had Encephalitozoon intestinalis, four Enterocytozoon bieneusi and four both species. An inverse and statistically significant relationship between the CD4 count and the presence of microsporidia in the fecal sample was also found. It is remarkable the high prevalence of microsporidia species observed in the HIV patients studied, with a predominance of E. intestinalis.

    Background and Aim. Insulin resistance (IR) is a prominent pathophysiologic component in a myriad of metabolic disorders, including obesity, prediabetes, and type 2 diabetes mellitus, which are common in our locality. The objective of this study was to determine the prevalence of IR and factors associated with this condition in an adult population from Maracaibo city, Venezuela. Methodology. A cross-sectional, descriptive study with multistaged randomized sampling was carried out in 2026 adults. IR was defined as HOMA2-IR ≥ 2. A multiple logistic regression model was constructed in order to evaluate factors associated with IR. Results. The prevalence of IR was 46.5% (n = 943), with 46.7% (n = 450) in the general population, 46.4% (n = 493) in females, and 47.90% (n = 970) in males (p = 0.895). IR prevalence tended to increase with age and was significantly greater in subjects aged ≥30 years (χ (2) = 16.726; p = 2.33 × 10(-4)). Employment, alcohol consumption, obesity, high triacylglycerides, low HDL-C, and dysglycemia were associated with greater odds of IR, whereas a high level of physical activity appeared to be weak protective factor against IR. Conclusions. The prevalence of IR is elevated in our locality. The main determinants of this condition appear to be the presence of obesity, high triacylglycerides, low HDL-C, dysglycemia, and alcohol intake.

    The biological transmission of Tomato Venezuela virus (ToVEV) by biotype B of the whitefly species Bemisia tabaci (Gennadius) increased (21.7-95.0%), and the time for symptom expression decreased (16-12.6 days) as the number of viruliferous whiteflies allowed access for inoculation to susceptible tomato plants increased from 1 to 20 adults/plant. When acquired only as a nymph, adults of this biotype transmitted the virus to 88.3% of susceptible tomato plants, using 15 viruliferous individuals per test plant, corroborating the circulative nature of the transmission. Disease incidence further increased (up to 100%) when the individuals were allowed to feed again on a virus-infected plant as adults. Leaf area, plant height and dry matter were significantly affected in ToVEV infected tomato plants.

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

    1993-08-01

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

    To determine the predictive power of various anthropometric indices for the identification of dysglycemic states in Maracaibo, Venezuela. A cross-sectional study with randomized, multi-staged sampling was realized in 2230 adult subjects of both genders who had their body mass index (BMI), waist circumference (WC) and waist-height ratio (WHR) determined. Diagnoses of type 2 diabetes mellitus (DM2) and impaired fasting glucose (IFG) were made following ADA 2015 criteria. ROC curves were used to evaluate the predictive power of each anthropometric parameter. Area under the curve (AUC) values were compared through Delong's test. Of the total 2230 individuals (52.6 % females), 8.4 % were found to have DM2, and 19.5 % had IFG. Anthropometric parameters displayed greater predictive power regarding newly diagnosed diabetics, where WHR was the most important predictor in both females (AUC = 0.808; CI 95 % 0.715-0.900. Sensitivity: 82.8 %; specificity: 76.2 %) and males (AUC = 0.809; CI 95 % 0.736-0.882. Sensitivity: 78.6 %; specificity: 68.1 %), although all three parameters appeared to have comparable predictive power in this subset. In previously diagnosed diabetic subjects, WHR was superior to both WC and BMI in females, and WHR and WC were both superior to BMI in males. Lower predictive values were found for IFG in both genders. Accumulation of various altered anthropometric measurements was associated with increased odds ratios for both newly and previously diagnosed DM2. The predictive power of anthropometric measurements was greater for DM2 than IFG. We suggest assessment of as many available parameters as possible in the clinical setting.

    Crude oils of Eocene fluvio-deltaic reservoirs in {open_quotes}Bloque V{close_quotes} and {open_quotes}Centro Lago{close_quotes} fields in the center of the Maracaibo Lake show many differences in composition, which are due to stratigraphically and structurally controlled reservoir geometry and a low rate of in-reservoir mixing of at least two successive petroleum charges. Oils produced from the top of structural highs contain 18(H) oleanane, higher Pr/Ph and C{sub 23-3}/C{sub 24-4} ratios, a lower proportion of DBT/P compounds, and clearly different fingerprint patterns in the C{sub 6}-C{sub 15} range, than those observed in oils produced from the lower parts of the structures. These compositional differences suggest that two source rocks, or two distinctive organic facies within the same Cretaceous La Luna Formation, generated and filled vertically poorly connected Eocene reservoirs. On the other hand, saturate-biomarkers ratios, triaromatics (C{sub 21}/C{sub 21}+C{sub 28}), n-paraffins (n-C{sub 20}/n-C{sub 29}) and n-heptane index suggest that oils in upper reservoirs are slightly less mature than oils in lower reservoirs and, consequently filled the structure first. Additional evidence from formation water analysis and tectonic basin evolution allow us to interpret at least two petroleum pulses from Cretaceous source rocks during Upper Miocene to present day kitchens located in the Andes foredeep at the southeast of the study area.

    Full Text Available The objective of this investigation was to determine the physical and chemical composition of the water streams and sediments of the Maracaibo Lake in three sampling areas located in Tía Juana, Lagunillas and Ceuta in order to know the level of contamination and assess water quality based on permissible values established by the 883 Decree. The results indicate that the overall hydrocarbon concentrations in the water and sediments are above permissible levels. It is concluded that petroleum prospection is the root cause of the lake contamination.

Es de interés para la historiografía venezolana y latinoamericana profundizar en el análisis de la realidad que explica la reacción de una “ciudad disidente” como Maracaibo, cuya elite prefirió seguir los lineamientos de la Regencia, elegir su diputado para las Cortes de Cádiz y defender su autonomía, antes que aceptar la propuesta de emancipación caraqueña. Bajo esta perspectiva se pretende esclarecer si la elite maracaibera fue realmente “disidente” del movimiento caraqueño por inercia histórica, larga herencia hispánica, o su actuación estuvo apegada a la legitimidad del momento como una opción política para lograr reafirmar y acrecentar su autonomía dentro del régimen monárquico. La investigación se ubica en la actual corriente historiográfica europea e hispanoamericana que sale al paso a los tradicionales análisis sustentados en una visión fáctica y localista, ignorando la amplitud temporal y espacial del proceso; se centra en el conocimiento que aporta el estudio comparado de la actitud de Maracaibo ante la Independencia con su desarrollo en el resto del país y acontecimientos en el mundo hispánico.

    Magnitude of vertical fluid movement and rates of quartz cementation were studied in three cored intervals where reverse faults cut the Eocene Misoa Fm in the Maracaibo basin, Venezuela. The faults are flower type structures, with slips up to 500 meters, generated by an Eocene inversion of Cretaceous-Paleocene normal displacements. The fault zones extend 2.5 meters away from the slip surface and are characterized by extensive quartz and chert precipitation associated with microfractures and cataclasis. Kinetic modeling of quartz precipitation suggests that the rates of microfracture annealing may have been initially up to 0.25 moles/C, lasting approximately 1 my after faulting started (37.5 mya) and subsequently decreasing during uplifting to less than 0.05 moles/C. Kinetic modeling suggests that quartz cementation along these reverse faults may have occurred in short periods of time and at approximately the same or lower rates than intervals away from faults. Minimum vertical distance of fluid flow along one fault zone was calculated with two different approaches. The first method divides the thermal gradient present during faulting (obtained through a thermal reconstruction of the area) by a difference between the host rock maximum burial temperature and fault cements temperatures (obtained from fluid inclusions). The second method integrates an average-weight function of the thermal gradient along the unknown depth. Both methods suggest that hot fluids, present during cementation, ascended a minimum of 450 to 800 meter along the fault zone.

    The purpose of the present work was to determine the plasma concentrations of fibrinogen and Von Willebrand Factor (VWF) as well as platelet aggregation, in an apparently healthy population of 306 men and 41 women, 33 to 65 years of age, workers of the national oil industry (PDVSA, Maracaibo), as a base investigation in a 5-year prospective national collaborative study. The participants were previously subjected to a thorough clinical examination with cardiovascular evaluation and laboratory tests. Clottable fibrinogen and VWF concentrations were determined in platelet poor plasma, the last one by immunoclectrophoresis, and a multimeric analysis of VWF was performed on those plasmas with concentrations higher than 150 U/dL by SDS agarose electrophoresis, followed by cellulose membrane transference. Platelet aggregation was studied in platelet rich plasma with no addition of stimulants and after collagen and ristocetin were added. Forty per cent of men and 65.8% of women, showed fibrinogen concentrations above 300 mg/dL (p < 0.01) and 12.2% of men and 15.4% of women had VWF values higher than 150 U/dL, with normal multimeric distribution. Fourteen individuals presented spontancous platelet aggregation and increased aggregation in 12 and 13 of them, after induction with collagen and ristocetin respectively. Comparing these findings with those of previous collaborative studies from other countries, the present results could mean that an important proportion of the population here studied, could be at risk for a future coronary event; however, as these are the base findings in Maracaibo, the significance of our results will be better evaluated at the end of the five year study.

    To detect the presence of microsporidia and other enteric parasites in patients with HIVAIDS of the Autonomous Services University Hospital of Maracaibo (SAHUM), where there are no previous studies in this field. Fecal samples were analyzed by means of direct exam, concetration method with formal-ether, Kinyoun coloration and fast Gram-Chromotrope coloration. Separate PCR were perfomed to differentiate Entamoeba histolytica and Entamoeba dispar , when the E. histolytica/E. dispar complex was observed in the microscope. Information on the patient was obtained trough clinical history. Of 56 individuals that participated, 38 (67.86%) presented some commensal parasite and/ or pathogenic species in their fecal sample. Carriers of pathogenic species were predominat (26/38). Protozoa such as Isospora belli protozoa (17.65%), Blastocystis spp. (17.65%), Cryptosporidium spp. (7.84%), E. histolytica/E. dispar (5.88%), Entamoeba coli (3.92%), Giardia lamblia (3.92%), Endolimax nana (3.92%), Cyclospora cayetanensis (3.92%), and Chilomastix mesnilli (1.96%) were diagnosed. Among the helminths, Ascaris lumbricoides, Trichuris trichiura and Strongyloides stercoralis , had a percentage of 27.27% each, and Hymenolepis nana , 18.18%. Entamoeba histolytica was only detected in one of three cases presenting complex microscopic examination. By Gram-chromotrope, 17 samples showed spores of the Microsporidia phylum, equivalent to 33.33% prevalence. Microsporidia may be first prevalente in HIV positive patients when specific diagnostic techniques are used.

    The effect of weathering of organic matter in the La Luna Formation, the main source rock of Cretaceous oil in Western Venezuela was studied by means of organic petrography. Two outcrop samples from zero to about 10 cm depth were studied microscopically, both in whole rock and kerogen extract mode. This permitted recognizing some characteristics and consequences of weathering, such as: increased porosity of huminite and solid bitumens and the decrease of its reflectance (% anti Ro); disappearance of micrinite, presence of exudation substances and lower fluorescence emission of liptinite under blue light excitation. The mass reduction of the organic matter was determined by the difference of total organic carbon values, and by the weight reduction of the sample before and after extraction, in both weathered and unweathered samples. The loss of organic matter by weathering is considerable, as much as 87% in the first 0.5 cm of the weathering halo are lost.

    The atmospheric gases and aerosols coming from various natural and anthropogenic emissions are incorporated into raindrops through various physicochemical processes during rain events. Knowledge of the chemical composition of precipitation is critical to understand regional and local air pollution and its effects on the ecosystems. Sulfur, nitrogen and chlorine compounds are mainly involved in rain acidity production as acidic or potentially acidic species. An important factor in the acid-base characteristics of rain is the emission of alkaline materials such as calcium-magnesium carbonates and ammonia, generally found as a vapour responsible to sulfuric and nitric acids neutralizing. Rain chemistry reported in this work originates from several sites of the city of Maracaibo and the rainwater samples were gathered in three periods between 1989 and 2001, using manual and automatic samplers. The different analyses were made using a flame atomic absorption spectrometer, Perkin-Elmer 3110 and an ion chromatography equipment with a conductivity detector, Dionex 2000i/SP. The pH-PPV in Maracaibo rainwater was 4.8, indicating an atmosphere lightly acid and influenced by SO{sub 4}{sup -2}, Cl{sup -} and NO{sub 3}{sup -} in 86 %. NH{sub 3} is the most important neutralizing species, though the concentrations of Ca{sup +2} and Mg{sup +2} are additional contributions to atmospheric neutralizing process. The major flow of wet deposition was exhibited by NH{sub 4}{sup +}, SO{sub 4}{sup -2}, Cl{sup -} and NO{sub 3}{sup -} with 67.5 %. Statistically, a high correlation was found between SO{sub 4}{sup *}, Cl{sup *} and NO{sub 3}{sup -} ions with the H{sup +} ion (p<0.05), ratifying its influence in the acidity of Maracaibo's rain. It is concluded that a small fraction of the acid potentially ions contributes to free acidity of the rains, due to the neutralizing capacity of NH{sub 3}, Ca{sup *} and Mg{sup *}.

    To determine the prevalence of Entamoeba histolytica as a producer of diarrhea, a study was conducted in children, less than five years of age, with diarrhea who attended several out patient clinics of the Servicio Aut6nomo Hospital Universitario, Maracaibo, Venezuela. A macroscopic and microscopic examination with physiological saline, lugol and Kinyoun staining were performed to the stool samples obtained. The remainder of the sample was frozen until DNA extraction, and PCR amplification was performed separately for E. histolytica and E. dispar. Microscopic examination showed no trophozoites and/or cysts of Entamoeba histolytica/dispar/moshkovskii, or intestinal coccidians in any of the 50 samples analyzed. Parasites detected were Giardia lamblia (6%), Blastocystis sp. (4%), Pentatrichomonas hominis (2%), Ascaris lumbricoides (2%) and Trichuris trichiura (2%). By PCR, six samples (12%) had DNA of E. dispar and two (4%) had DNA from E. histolytica; no child showed association of both amoebae. The two children who had E. histolytica were one-year-old. E. dispar was detected in younger children. We suggest that the prevalence of E. histolytica in children under five years is really low.

Se plantea desde la perspectiva de la comunicación, buscando establecer cómo ésta interviene en el proceso de formación de la cohesión social, en el ámbito específico de la sociedad marabina. Se trabaja con un enfoque teórico plural y se construye un modelo de análisis a partir de la comparación entre las realidades materiales y simbólicas, en Maracaibo. Dos conclusiones relevantes son: primero, que la potencialidad tecnológica de los medios y su capacidad para generar una amplia gratificación sobre la audiencia contribuye a matizar las carencias materiales y las contradicciones sociales. Segundo, en la actualidad la exigencia de construir ciudadanía supone un ejercicio que se sustente en condiciones de mayor igualdad en el intercambio comunicativo.

    Full Text Available Insulin Resistance (IR is an important finding in several diseases including diabetes and metabolic syndrome, and its diagnosis seems pertinent during the evaluation of insulin sensitivity, though mathematical models like HOMA (Homeostasis Model Assessment. The purpose of the present study was to determine an appropriate cutpoint for HOMA-IR in adult individuals from the Maracaibo municipality, Zulia state, Venezuela. Two-thousand and twenty-six individuals from both sexes and beyond 18 years of age were selected from the Maracaibo city Metabolic Syndrome Prevalence Study, a descriptive cross-sectional study with multietapic sampling. HOMA-IR was calculated using the formula [Fasting Insulin (µU/L x Fasting Glycemia (mmol/L/22,5]. To estimate the cutpoint, 602 healthy individuals were selected and a percentile distribution was calculates, alongside ROC Curve in order to identify the best cutoff point according to sensitivity and specificity. Overall, the average HOMA-IR was 3,71±3,01, with 3,65±2,96 for women and 3,76±3,06 for men (p=0,397. Using the reference population, the resulting arithmetic value was 2,64±1,67. When distributing per percentile, p75 was 3,02. When selecting a cutpoint using ROC Curve, the chosen cutoff point was 3.03 with an Area Under the Curve of 0.814 (75,2% sensitivity and 75,6% specificity. The obtained results are good enough to propose a cutpoint of 3,00 for HOMA-IR, which can be use in the clinical evaluation of IR in adults from our population

    Full Text Available Se presenta en este trabajo una aproximación antropológica a las representaciones culturales del honor femenino circulantes en la ciudad de Maracaibo, Venezuela, a finales del siglo XIX. La investigación realizada adopta un enfoque teórico-metodológico de corte estructuralista-constructivista, abordando el orden social como un sistema simbólico organizado según una lógica de la diferencia y partiendo de la premisa de que prácticas y representaciones están orientadas externamente por las estructuras objetivas de la sociedad, e internamente por esquemas de percepción, pensamiento y acción de origen social. Al tratarse de un trabajo de antropología histórica, los informantes fueron sustituidos por fuentes documentales ubicadas en diferentes archivos venezolanos. Se encuentra que las representaciones culturales del honor femenino en la sociedad en cuestión asociaban este concepto con la castidad sexual, reproduciendo esquemas culturales vigentes en la órbita del mundo occidental y proporcionando una lógica para el mantenimiento de relaciones desiguales de género y poder en la vida pública y privada de los marabinos. El capital social y el capital simbólico habrían sido componentes fundamentales del capital total de que se disponía entonces en la lucha cotidiana por la obtención de recursos y por el reconocimiento social, en una economía de bienes simbólicos que atribuía al parecer preferentemente a los hombres el trabajo oficial de conservación o incremento de dichas formas de capital.

Se evidenció que el método de acceso a la cavidad oral empleado en la autopsia bucal pre-inhumación facilitó el abordaje para la autopsia post-exhumación, sin provocar mayor destrucción de los tejidos blandos y permitiendo la correcta manipulación tanto de las estructuras orales como de los dispositivos protésicos aportados como evidencias. En todos los casos se verificó la coincidencia de los datos obtenidos durante la autopsia pre-sepultura. Se concluye que cuando el proceso de inhumación se lleva a cabo siguiendo una adecuada planificación, se facilita una futura recuperación del cadáver cuando esta es requerida para completar el procedimiento de identificación.In view of the petition presented by the relatives of the unidentified victims of the Sabaneta Jail Massacre, Maracaibo, Venezuela, a court ordered the exhumation of four corpses, fifteen days after they were buried. The remains were well preserved, the structure and facial outline were well conserved. It was evidenced that the method of access to the oral cavity employed in the pre-inhumation buccal autopsy facilitated the approach to the post-inhumation autopsy, without causing major destruction of the soft tissues and allowing for the correct manipulation of the oral structures as well as of the prosthetic appliances presented as evidence. In all cases, the coincidence of the data obtained during the pre-burial autopsy was verified. It was concluded that adequate planning of the inhumation process facilitates future recuperation of the bodies when this is required to complete the identification procedure.

    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.

    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 {delta}{sup 13}C and {delta}{sup 15}N signals, suggesting a primary autochthonous (algae and macrophytes) organic matter origin. The occurrence of large amounts of C{sub 23} and C{sub 25} relative to C{sub 29} and C{sub 31}n-alkanes indicated substantial inputs from submerged/floating macrophytes. The variations of C{sub 32} 15-keto-ol, tetrahymanol, diploptene, C{sub 32} 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. The importance of trenching in paleoseismic studies in Venezuela: brief historical summary

    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

The research shows an emerging paradigm with an interpretative, quantitative and qualitative focus, which lead to the use of methodological triangulation. This is an exploratory research on its first phase, and a descriptive one on its second phase, the field work. A non-experimental, transversal design was structured. The population was composed by seven (7 Directors: four (4 of hospitals, three (3 of the national health clinics, as well as four hundred (400 patients. The collection of data was carried out through the technique of interviews, with open questions for the first population, so as to measure the quality of service offered by the health centers. The technique used for the second population was a survey and the questionnaire was the instrument. This instrument was structured by means of a scale combination, which allowed first to measure the perception the patients have for the service they receive, and second to determine the factors that impact the quality of this service. The test of dependability was applied by means of the coefficient of the two halves throwing 0.90% for the second. As a conclusion, it was determined that the administrators don’t perceive service as a main variable or strategy, but rather as an obligation, so it is necessary to make changes both at the level of moral values, and at the perceptive process. Therefore, it is recommended that hospitals and national health clinics respond with actions on aspects where

    During the period of 1979-1990 job-related injuries were studied in Maracaibo, Zulia state, in order to analyze frequencies and causes. This information was obtained from annual reports on job-related injuries Form Number 15-411 of the Venezuelan Institute of Social Security (IVSS) which has been implemented nationally since 1982. Accidents that caused loss of man-hours were considered; variables considered were: age, risk category, day of the week, work shift, month, type of accident, agent, type of lesion, mechanical cause, body part affected and type of the activity in which the company is involved. The results were expressed as absolute values (mean +/- SE) and relative values. The mean accidents/year was 1651 +/- 177.97, most of them occurring in the age groups of 20-29 years (368.8) and 30-39 years (359.8). The triannual mean rate was higher for the group of the non-serious accidents (50%). Tuesday was the day of higher accidental incidence (22%) in addition to the morning shift between 9 and 11 hours (55%). Manufacturing was the economic activity most affected (43%). The most common causative agents were materials, substances and radiations (35%). The use of defective tools were the most frequent causes of mechanical accidents (31%). Upper limbs (46%) and between the type of lesion contusions or/and bruises (53%). It was concluded that, although the number of workers and accidents slowly diminished, the accidents rate slightly increased.

    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

    Lack of adequate information about the taxonomic and evolutionary relationships, ecology, biology, and distribution of several species belonging to the family Potamotrygonidae makes these species vulnerable to anthropic activities, including commercial overexploitation for the ornamental fish market. The aim of this study was to investigate the systematic relationships among genera and species belonging to this family by analyses of three mitochondrial gene regions. Samples were collected from the main river basins in Colombia and Venezuela for four genera and seven species of the family, as well as for what appear to be unidentified species. Three mitochondrial molecular markers COI, Cytb, and ATP6 were amplified and sequenced. Maximum likelihood and Bayesian inference analysis were performed to obtain topologies for each marker and for a concatenated dataset including the three genes. Small dataset may compromise some methods estimations of sequence divergence in the ATP6 marker. Monophyly of the four genera in Potamotrygonidae was confirmed and phylogenetic relationships among members of the Potamotrygon genus were not clearly resolved. However, results obtained with the molecular marker Cytb appear to offer a good starting point to differentiate among genera and species as a tool that could be used for barcoding. The application of this gene as a barcode could be applied for management and regulation of extraction practices for these genera. Sequencing complete mitochondrial genomes would be the next step for testing evolutionary hypothesis among these genera. Population structure analyses should be undertaken for Paratrygon, Potamotrygon magdalenae and motoro.

    The La Luna Formation, main source rock of the Maracaibo Basin was studied by conventional geochemical parameters, used to determine the maturity, and they were compared with the physic-chemical and molecular properties of the asphaltenes present in the bitumen of the rocks. Three wells were studied (A, B and C) with a total of 13 samples. Based on Rock-Eval results the organic matter in well A (455 deg C Tmax) shows a relatively high level of maturation (top of the oil window), whereas the organic matter in well B (435 - 436 deg C Tmax) is in the beginning of the oil window. Tmax values in well C (438 - 446 deg C) and well C suggest an intermediate maturity level. The biomarkers identified in well B and C show ratios indicating an equilibrium state in the maturity level. A good correlation was found comparing the conventional analytical data with the determination of maturity level obtained from the asphaltenes precipitated from the bitumen of the samples. With increased maturity levels the H1 NMR analysis showed enrichment in aromatic molecules in relation to aliphatic, due to the bitumen aromatization process. Similarly, the asphaltenes molecular weight has higher values in samples characterized by elevated maturity levels. This confirms earlier studies that showed that asphaltenes may be utilized as maturity parameter of organic matter. (author)

    The saline degradation of soils that are irrigated with brackish water is worrisome increasing worldwide, and it may further affect the salinity of fresh water in those streams flowing across. The problem that is caused by an increasing concentration of salts that are more soluble than gypsum depends on the quality of irrigation water, climatic aridity, and drainage limitations. All these conditions meet in the alluvium soils of River Limón basin that are crossed by Caño San Miguel irrigation paleochannel. River Limón's regulation by closing Manuelote and Tulé artificial reservoirs has diminished the input of water and sediments from flooding events, which exerted dilutive effects in the past. In addition, the balance of soluble salts in these soils has also registered further net accumulation during those extremely dry years happened before 2006, because the great dilution contribution of ombrogenic dammed water coming from rain has not been enough to compensate salts concentration generated by water evapotranspiration in those irrigated soils of the middle basin, particularly in the absence of superficial runoff and deep drainage. Considering those semi-arid climate conditions prevailing in the area (annual precipitation = 710 mm; potential evapotransporation = 2361 mm), it resulted that water analyses in River Limón showed a ten-fold increased maximum annual salinity concentration (March) along the stream; that is, an electric conductivity (Ce) of 0.37 dS•m-1 (at 25 °C) at Puente Carrasquero pumping station, where water for crop irrigation is subtracted, turns to 34.60 dS•m-1 (at 25 °C) at its base level in Puerto Mara, where it discharges to Lake Maracaibo. In addition, the quality of irrigation water from Caño San Miguel, which aggregates to those coming from River Limón at the pumping station located in Carrasquero just before running through the alluvium of this water stream, resulted pretty irregular. In short, it spanned form C1 to C4 soil

    Full Text Available The contamination and risk assessment of heavy metals in the bottom sediments of the Lake Valencia, Venezuela, was performed by determining the Enrichment Factor (EF, the Geoaccumulation Factor (Igeo, the availability of metals and the Risk Index Code (RAC. The sediments were anthropogenic ally enriched with Pb, Zn, Cu and Cr and classified as uncontaminated to moderately contaminated, with a medium risk of Zn, Co, Ni and Cr, and low risk of Cu, Pb and Cd. Analysis of correlations and PCA showed temporal variations in the concentration of metals in the sediments during the rainy season, and spatial variations, where the depth and anthropogenic inputs are the main variables. The contamination of sediments was located on the axis connecting the mouths of the river Guayos, which crosses the city of Valencia, and the river Güey which crosses the city of Maracay, both highly industrialized. Although the concentration of dissolved heavy metals into the waters was within the regulations, important concentrations of Pb and Hg and the bioaccumulation of Hg and Cr, determined by the Bioconcentration Factor (BCF, were found in the fish tissues which indicate that the metal enrichment of the lake sediments is affecting the biota.

    In order to analyze the frequency, injury rate and cause of on site accidents to the hands of workers on the east coast of lake of Maracaibo in Zulia State, data was obtained from the accident reports registered with the Venezuelan Institute of Social Security. An occupational hand injury was defined as a traumatic injury to the hands, fingers or wrists that occurred while the employee was at work; that resulted from a single exposure to a hazardous agent. The following variables were analyzed: age, severity, economic activity, material agent, mechanic cause, type of injury, type of accident and unsafe action. The frequency rate was used to analyze the annual accident rate. During the period under study 2.456 injuries to the hand were registered, representing 36% of the total injuries reported; 95% were light injuries, 5% incapacitating and two cases resulted in the death of the worker. 72% of the injuries were located in the fingers, 22% in the hands and 6% in the wrists. The greatest frequency of injuries were found in the economic activity in mines and quarries with a rate of 123.1 per thousand. The age group most affected was of 20-29 years (42%), Wounds or contusions and crushings were the injuries most commonly reported, in 39% and 36% of the cases respectively. The main type of injuries were caused by run over, running into or blow from objects. The principal agents causing injuries were materials, substances and radiations in 45% of the cases. It is concluded that the hand injury rate is very high in the exploitation of mines and quarries and represents the main cause of worker's disability.

    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.

    The Lake Maracaibo Basin in North Western Venezuela has the highest annual lightning rate of any place in the world (~ 200 fl km- 2 yr- 1), whose electrical discharges occasionally impact human and animal lives (e.g., cattle) and frequently affect economic activities like oil and natural gas exploitation. Lightning activity is so common in this region that it has a proper name: Catatumbo Lightning (plural). Although short-term lightning forecasts are now common in different parts of the world, to the best of the authors' knowledge, seasonal prediction of lightning activity is still non-existent. This research discusses the relative role of both large-scale and local climate drivers as modulators of lightning activity in the region, and presents a formal predictability study at seasonal scale. Analysis of the Catatumbo Lightning Regional Mode, defined in terms of the second Empirical Orthogonal Function of monthly Lightning Imaging Sensor (LIS-TRMM) and Optical Transient Detector (OTD) satellite data for North Western South America, permits the identification of potential predictors at seasonal scale via a Canonical Correlation Analysis. Lightning activity in North Western Venezuela responds to well defined sea-surface temperature patterns (e.g., El Niño-Southern Oscillation, Atlantic Meridional Mode) and changes in the low-level meridional wind field that are associated with the Inter-Tropical Convergence Zone migrations, the Caribbean Low Level Jet and tropical cyclone activity, but it is also linked to local drivers like convection triggered by the topographic configuration and the effect of the Maracaibo Basin Nocturnal Low Level Jet. The analysis indicates that at seasonal scale the relative contribution of the large-scale drivers is more important than the local (basin-wide) ones, due to the synoptic control imposed by the former. Furthermore, meridional CAPE transport at 925 mb is identified as the best potential predictor for lightning activity in the Lake

    Full Text Available In the present work, an integrated approach has been made to understand the primary migration of oil in the organic-rich, oil prone, predominantly carbonate source rocks of the La Luna Formation of the Maracaibo Basin. Geochemical data on source rock extracts and the simulation of oil generation by hydrous-pyrolysis experiments indicate that the primary migration and expulsion of oil began at an early stage of thermal maturity and that the bulk oil expulsion at peak generation could have been as high as 75%. Fluorescence and transmitted light petrography of the source rocks at different maturity levels show the dominant mode of oil expulsion through microfractures. It is interpreted from the geochemical and geological data that the primary migration of oil in the La Luna source rocks took place as a separate oil phase through microfractures caused by the excess fluid pressure due to hydrocarbon generation. The oils expelled from the La Luna source are enriched in saturated hydrocarbons and depleted in resins + asphaltenes compared to the La Luna rock extracts. However the distributions of n-alkanes, in the oils and the rock extracts are very similar, which suggest that fractionation of the n-alkanes did not occur during the primary migration. In the Maracaibo Basin, updip lateral primary migration of oil within the La Luna source system seem to have occurred for a considerable distance. Local internal migration has been observed at a relatively early stage of maturity. Cette étude consiste en une approche intégrée cherchant à comprendre la migration primaire de l'huile dans les roches mères de la Formation de La Luna dans le bassin de Maracaïbo, riches en matière organique, génératrices d'huile et à dominante carbonatée. Les données géochimiques sur des extraits de roches mères et la simulation de genèse d'huile par des expériences de pyrolyse en présence d'eau indiquent que la migration primaire et l'expulsion de l'huile ont

    The tropics play a major role in the global hydrologic cycle and changes to tropical rainfall patterns have critical implications for water resources and ecosystem dynamics over large geographic scales. In tropical South America, late Pleistocene and Holocene precipitation variability has been documented in geologic records and associated with numerous external and internal variables, including changes in summer insolation, South American summer monsoon strength, Pacific Ocean sea surface temperatures, continental moisture recycling, and other climate processes. However, there are few records from the northern hemisphere tropical Americas, a key region for understanding interhemispheric linkages and the drivers of tropical hydroclimate variability. Here, we present a ~13 ka record of coupled hydroclimate and environmental changes from Laguna Brava, a small (~0.07 km2), hydrologically closed lake basin situated at 2400 m asl in the Cordillera de Mérida, Venezuela. Sediment cores collected from varying water depths and proximity to shore are placed in a chronologic framework using radiocarbon ages from terrestrial macrofossils, and analyzed for a suite of physical, bulk geochemical, and stable isotopic parameters. Compound specific hydrogen isotope (D/H) measurements of terrestrial plant waxes (long-chain n-alkanes) show a sharp increase in the late Pleistocene, followed by a long-term trend toward more negative values that suggest a ~20‰ decrease in the D/H ratios of South American tropical precipitation during the Holocene. This pattern is consistent in sign and magnitude to other South American precipitation reconstructions from both hemispheres, indicating interhemispheric similarities in tropical hydroclimate variability. Superimposed on this continent-scale trend are changes in moisture balance and environmental conditions in the Venezuelan Andes. We reconstruct these parameters at Laguna Brava at multidecadal and centennial resolution and evaluate this

    2001-01-15

    To explore a possible connection between specific environmental factors that might explain the high rates of stomach cancer in people living in the highlands of western Venezuela, an epidemiologic study was conducted in 2 regions of contrasting topography. The regions embrace 3 Andean states, Mérida, Táchira and Trujillo, and the vicinal lowland surrounding the Maracaibo lake basin of Zulia State. Statistical sanitary records from 1986 to 1996 comprising 5.5 million people in the study area indicated that age-sex-adjusted gastric cancer death rate per 100,000 people (DR) was up to 3.64 times higher in highland than lowland areas, although total cancer-related DRs were comparable in both regions. DRs of other less frequent cancers from the upper alimentary tract [esophagous (1.18/0.99) and mouth-throat (1.39/2.64)] showed comparable values in both regions as well as colorectal, breast, and uterus-cervix cancers, suggesting that the stomach cancer DRs were related to geographically determined factors. Comparison of some nutrition issues, incidence of Helicobacter pylori infection in selected areas, the discovery of the bracken carcinogen ptaquiloside in milk from bracken-fed cows, the prevalence of this plant in mountain cattle households and pasturelands and the rates of bracken-evoked bovine enzootic hematuria led us to conclude that consumption of ptaquiloside-contaminated milk may contribute to human gastric cancer in the Andean states of Venezuela.

    Full Text Available En Venezuela el aseo urbano es considerado un servicio básico, cuya responsabilidad recae sobre los gobiernos locales. En tal sentido por ser catalogado básico, las fallas en la prestación del servicio genera manifestaciones de malestar de la población, como es el caso de la ciudad de Maracaibo, comportamiento que ha experimentado un auge, tanto por las graves consecuencias en la salubridad, como la incomodidad estética y el impacto ambiental ocasionados. Esto ha hecho pertinente, determinar la calidad del servicio público de aseo urbano domiciliario en el municipio Maracaibo, parroquias Francisco Eugenio Bustamante y Antonio Borjas Romero, constituyendo el objetivo principal del presente artículo. El diseño de investigación fue no experimental de campo, con un tipo de estudio descriptivo, para lo cual se elaboró y aplicó un instrumento de medición de la calidad con base en la percepción del usuario, siguiendo un muestreo por etapas. Finalmente, se obtuvo una medición de la calidad de servicio valorada en 2.228, en una escala de 1.0 a 5.0, siendo 5.0 la máxima puntuación. En consecuencia se concluye que el nivel de calidad de servicio en las parroquias estudiadas es bajo.

    Three-dimensional seismic data are increasingly being used in reservoir characterization studies as an aid in detecting and delineating structural and lithologic features as well as changes in fluid distribution that may not be resolvable with log data at wide well spacings. Amplitude maps, in addition to displaying distribution of lithology, can also be effective in inferring subtle faults associated with changes in reservoir fluid content. In a 12-month reservoir characterization study of tide-dominated deltaic and shelf reservoirs of the Lower Eocene Misoa Formation in a 4-m{sup 2} (10.4-km{sup 2}) rectangular are (Phase III Area) in the Bloque I Area, 3-D seismic data were used in conjunction with logs from approximately 50 wells to detect delineate faults and to infer interwell sand-body distribution. The goal of this reservoir analysis analysis was construct an improved geological model of oil-and gas-productive reservoirs in the Lower Eocene to better understand controls on reservoir compartmentalization and to identify areas of unswept hydrocarbons. This paper provides examples from the C4 Member and demonstrates how 3-D seismic data were used to infer the presence of faults not previously detected in earlier studies of these reservoirs with conventional log data and to illustrate their control on fluid distribution.

    Full Text Available INTRODUCTION: Obesity is a worldwide public health issue. Since the epidemiological behaviour of this disease is not well established in our country, the purpose of this study was to determinate its prevalence in the Maracaibo City, Zulia State- Venezuela. MATERIALS AND METHODS: A cross-sectional study was undertaken using the data set from the Maracaibo City Metabolic Syndrome Prevalence Study. The sample consists of 2108 individuals from both genders and randomly selected: 1119 (53.09% women and 989 (46.91% men. The participants were interrogated for a complete clinical history and anthropometric measurements. To classify obesity, the WHO criteria for Body Mass Index (BMI, and Waist Circumference (WC from the IDF/NHLBI/AHA/WHF/IAS/IASO-2009 (IDF-2009 and ATPIII statements were applied. RESULTS: For BMI, obesity had an overall prevalence of 33.3% (n = 701, and according to gender women had 32.4% (n = 363 and men had 34.2% (n = 338. Overweight had a prevalence of 34.8% (n = 733, Normal weight had 29.8% (n = 629, and Underweight had 2.1% (n = 45. Adding Obesity and Overweight results, the prevalence of elevated BMI (>25 Kg/m(2 was 68.1%. Using the IDF-2009 WC's cut-off, Obesity had 74.2% prevalence, compared to 51.7% using the ATPIII parameters. CONCLUSIONS: These results show a high prevalence of abdominal obesity in our locality defined by the WHO, IDF-2009 and ATPIII criteria, which were not designed for Latin-American populations. We suggest further investigation to estimate the proper values according to ethnicity, genetic background and sociocultural aspects.

    2006-01-01

    Full Text Available La provincia de Maracaibo se insertó tardíamente al proceso independentista liderado por los mantuanos caraqueños. En enero de 1821, tras años de iniciada la guerra de independencia, el cabildo maracaibero en representación de sus vecinos, reconociendo sus atribuciones soberanas declara su adhesión al proyecto republicano, y se incorpora a la Gran Colombia, proclamada oficialmente por la Constitución de Cúcuta. Esta nueva forma de organización política forma parte de un proceso de transformación que se devela en la palabra pública y privada a través de pasquines, periódicos, folletos, proclamas, representaciones, tertulias, clubes entre otros. Esta proliferación de escritos y asociaciones generan cambios que definen el tránsito hacia la modernidad y a la conformación de una opinión pública. Desde estas consideraciones la opinión pública en Maracaibo respondió a un trabajo de pedagogía política por parte de quienes se consideraban republicanos, y difundieron progresivamente los ideales de la ilustración. Esta opinión pública fue encaminada primero hacia los ideales de la soberanía y la autonomía política durante la guerra de independencia, y más tarde hacia la conformación de un ideal nacional, tras consolidarse la República de Venezuela en 1830. En la conformación de esta opinión pública en Maracaibo desempeñaron un papel decisivo los nuevos espacios públicos como las diferentes sociedades económicas y de arte, que permitieron la difusión de las nuevas ideas y coadyuvaron a sentar las bases del nuevo ideal nacional

    Full Text Available El pueblo de Maracaibo aborigen y sus términos antecedió a lo que fue la ciudad-puerto de Maracaibo en los siglos XVI y XVII inserta en la expansión capitalista europea. La ventajosa situación de Maracaibo en el intermedio del agua lacustre y marítimas, propició la alternativa de comunicación entre los centros productores andinos-lacustres con el Caribe y el Atlántico. Factor aprovechado por las poblaciones del norte del Lago de Maracaibo para el dominio de la navegación lacustre que derivó en rivalidades económicas y políticas, tanto en los tiempos aborígenes como en los tiempos de sometimiento hispánico. Se trata de interpretar el crecimiento del puerto y su competitividad con los otros puertos lacustres como Moporo, Tomoporo, Gibraltar y Zulia por el control comercial, de los cuales dependió paradójicamente para su abastecimiento en razón de la esterilidad de las tierras maracaiberas. Tal proceso se estudió en el marco de la política mercantilista de los Austrias, a través del análisis histórico de las fuentes documentales del Archivo General de Indias.

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

    Bronchial asthma is an intercurrent disease that affects a major portion of the population. Neither its etiopathogenesis nor its complications have been fully established. The purpose of this study was to determine the composition of oropharyngeal bacterial flora in asthmatic patients and compare it with oropharyngeal bacterial flora in a group of healthy patients in order to establish its relationship with the pathogenesis of asthma and its complications. A sample consisting of 116 pharyngeal swabs was analysed from march 1995 to december 1996. 58 of the total amount of pharyngeal swabs corresponded to asthmatic patients (during asthmatic crisis), while the other 58 corresponded to healthy subjects. Common bacteriological culture techniques were carried out in order to obtain the bacteriological diagnosis. The results showed that isolation of transitory flora bacteria in asthmatic patients was 75.8%, which was significantly higher (p crisis. This data must be considered when applying empiric therapy in asthmatic patients complicated with pneumonia. The possibility that certain infectious agents, including bacteria, could play a role in asthma pathogenesis is one of the questions that should be answered in future studies on this topic.

    Full Text Available El presente trabajo se propone analizar el origen y volumen del financiamiento hospitalario durante el período 1998-2002, así como evidenciar los cambios en el comportamiento de la demanda de servicios con relación a la oferta y cobertura poblacional, y sus implicaciones en los costos de funcionamiento en dos hospitales públicos de la ciudad de Maracaibo (estado Zulia, Venezuela correspondientes a los niveles III y IV, representativos de diferentes modelos administrativos. Se efectúa el análisis de información documental obtenida mediante la realización de pasantías profesionales en los hospitales estudiados, por cuanto estas instituciones no procesan información administrativa de forma sistemática. Con base en el estudio realizado se establece que los servicios hospitalarios son financiados fundamentalmente con asignaciones presupuestarias para garantizar una determinada oferta, aun cuando ésta no responda a las necesidades. El gobierno regional impulsa una tendencia privatista orientada a incrementar la proporción de ingresos por venta de servicios, lo cual pone de relieve la búsqueda de eficiencia formal, sin enfatizar la reducción de costos. Por el contrario, el gobierno nacional se esfuerza en garantizar el financiamiento para la gratuidad constitucional de los servicios de salud. Se concluye que el financiamiento a la oferta, sin considerar el comportamiento de la demanda, se traduce en costos fijos de funcionamiento de los hospitales, que lesionan la eficiencia y la optimización de la cobertura.

    This study presents the results of an integrated reservoir study of the Eocene B-Inferior/VLG-3659, Area 7, Ceuta filed. This field located in the Maracaibo Lake in the western side of Venezuela. The objective was to evaluating the feasibility to implement a secondary recovery project by means of water flooding. Core information was used for this study (194 ft), PVT analysis, RFI, build-up and statistic`s pressure analysis, modem logs and production history data. Using geostatistical techniques (Kriging) it was defined a low uncertainty geological model that was validated by means of a black oil simulator (Eclipse). The results showed a good comparison of historical pressure of the reservoir against those obtained from the model, without the need of {open_quotes}history matching{close_quotes}. It means without modifying neither the initial rock properties nor reservoir fluids. The results of this study recommended drilling in two new locations, also the reactivation of four producing wells and water flooding under peripherical array by means of four injection wells, with the recovery of an additional 30.2 MMSTB. The economical evaluation shows an internal return rate of 31.4%.

  4. Tertiary evolution of the northeastern Venezuela offshore

    1998-12-01

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

    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)

Se analiza la búsqueda de eficiencia durante el periodo 1996-2002, en el Hospital General del Sur, ubicado en Maracaibo, cuya capacidad presupuestada es de 432 camas. El análisis parte de dos consideraciones: a planteamientos teóricos y jurídicos sobre la eficiencia como criterio de gestión; y b el comportamiento de la demanda de servicios con relación a la oferta y sus implicaciones en los costos de funcionamiento. Con base en el estudio realizado se concluye que los servicios del Hospital General del Sur son financiados con: a asignaciones presupuestarias de acuerdo a la oferta, aun cuando ésta no responda a las necesidades, lo cual genera un comportamiento ineficiente, por la falta de control; y b una tendencia incrementar la proporción de los ingresos por recuperación de costos, respecto a la asignación presupuestaria, que se invierte durante los dos últimos años, lo cual pone de relieve la búsqueda de eficiencia mediante el incremento de ingresos por cobro de los servicios de salud, sin enfatizar la reducción de costos.

    The target area of this study is the Maracaibo sedimentary basin located in the western part of Bolivarian Republic of Venezuela. The full-scale exploration and development for oil resources in Venezuela which was the greatest oil-producing country in South America had begun at the Maracaibo sedimentary basin in the 1910s, and it was a center of the oil product in Venezuela until the 1980s. But, in most of oil fields in the Maracaibo sedimentary basin, there is concern over the drain on recoverable reserves due to deterioration, and the production amount of petroleum in Venezuela has been diminishing these days. Leveling and GPS surveying were carried out in the past, and they revealed that the large-scale subsidence phenomenon of which cumulative subsidence amount was approximately 5 meter had occurred. The authors applied the vertical displacement measurement by InSAR time series analysis using PALSAR data obtained in the Fine-beam and ScanSAR observation mode. As a result, it could be confirmed clear ground deformation in the surrounding of three oil fields (Tia Juana, Lagunillas and Bachaquero) and easily recognized that the areas of phase anomalies detected by this analysis had expanded and the number of interference fringes had increased over time. The annual velocity of vertical ground surface displacement measured by InSAR time series analysis was -51 mm per year, -103 mm per year and -58 mm per year in Tia Juana, Lagunillas and Bachaquero oil field respectively. The tendency that an earth surface shifted towards the center of phase anomalies was detected from the result of the horizontal ground change measurement. It was interpreted from Google Earth and Landsat images that oil-related facilities (mainly bowling stations) were built intensively over the areas where phase anomalies were detected. Therefore, it was inferred that there was a high association between the operation activity of the oil field and ground deformation. In addition, the deterioration

    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

La metodología consistió en la revisión de referentes teóricos, aplicación de un cuestionario semiestructurado a los concejales y personal directivo de la Alcaldía y revisión de documentos de gestión local. Los resultados evidencian que las políticas de información al ciudadano se agrupan en: capacitación, recursos para la gestión de la información, medios de comunicación y mecanismos de participación; el modelo de gestión aplicado fue básicamente burocrático con ciertos visos participativos; en la formulación de las mismas prevaleció la pasividad del ciudadano y en la implementación no se reportaron indicios de seguimiento y control, solo cifras de actividades ejecutadas en las memorias anuales.

Una de las disposiciones aprobadas fue el cierre de los puertos de Maracaibo y La Vela, para las operaciones de importación y exportación realizadas desde los Andes venezolanos y colombianos, a través del Caribe. Estas funciones fueron transferidas al distante Puerto Cabello. Gran parte del occidente del país fue afectado por esta medida que no consideraba la larga tradición histórica de centros económicos que por centurias habían liderado las actividades agroexportadoras de sus respectivosámbitos comerciales. La medida no sólo perjudicó los intereses de la región histórica del Lago y de Coro, favoreció a grupos económicos rivales establecidos en la región norcentral, asociados con el presidente de la república. En el caso particular del Zulia, el cierre del puerto de Maracaibo afectó a financistas, pequeños y grandes comerciantes, transportistas, navegantes, marineros, productores y diferentes colectivos del estado; otros sectores perjudicados fueron los comerciantes vinculados con esta actividad en Colombia y Curazao.

    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)

This research aimed to determine associations between different physical activity levels and Lp(a) concentration. A descriptive and cross-sectional study was made in 1340 randomly selected subjects (males = 598; females = 712) to whom a complete clinical history, the International Physical Activity Questionnaire, and Lp(a) level determination were made. Statistical analysis was carried out to assess qualitative variables relationship by chi2 and differences between means by one-way analysis of variance considering a P value <0.05 as statistically significant. Results are shown as absolute frequencies, percentages, and mean +/- standard deviation according to case. Physical activity levels were ordinal classified as follows: low activity with 24.3% (n = 318), moderate activity with 35.0% (n = 458), and high physical activity with 40.8% (n = 534). Lp(a) concentration in the studied sample was 26.28 +/- 12.64 (IC: 25.59-26.96) mg/dL. Lp(a) concentration according to low, moderate, and high physical activity levels were 29.22 +/- 13.74, 26.27 +/- 12.91, and 24.53 +/- 11.35 mg/dL, respectively, observing statistically significant differences between low and moderate level (P = 0.004) and low and high level (P < 0.001). A strong association (chi2 = 9.771; P = 0.002) was observed among a high physical activity level and a normal concentration of Lp(a) (less than 30 mg/dL). A lifestyle characterized by high physical activity is associated with normal Lp(a) levels.

    The Prenatal Diagnosis Program of the Medical Genetic Unit of University of Zulia has the following objectives: Identification of Genetic Risk Factors (GRF) in those couples who attend to the Prenatal Genetic Clinic, application of different prenatal diagnostic procedures (PDP), and providing adequate genetic counseling. The goal of this paper is to show preliminary results obtained between January 1993 and December 1996. Three hundred and twenty one pregnant women were analyzed by determining the GRF and taking into account the genetic clinical history. The GRF analyzed were: Advanced maternal age (AMA), congenital malformation history (CMH), previous child with chromosomic anomalies (PCCA), defects of neural tube history (DNTH), congenital heart disease history (CHDH), any parent carrier of chromosomic anomaly (PCA), habitual abortion (HA), abnormal fetal echography (AFE), altered maternal serum levels of alpha-feto-protein (AMSAFP) and OTHERS: exposure to teratogenic agents, history of Mendelian diseases, maternal systemic diseases and anxiety in the mother or in her partner. The PDP was designed according to the GRF, which included fetal echography (FE), fetal echocardiography (FEc), amniocentesis (AMN), chordocentesis (CCT) and AMSAFP. Results showed that 58.4% of the expectant mothers asked for counseling during the 2nd trimester, 70% of the total showed only one GRF, and AMA was the most frequent GRF found (40.3%), followed by PCCA, AFE, CHDH, HA, DNTH, PCA, and OTHERS in that order. The specific PDP applied to the identified GRF allowed a health evaluation of the fetus. The GRF identification gave the opportunity of establishing a Prenatal Diagnostic Program producing a response to the couple's needs and showed the utility of an integral and multidisciplinary management directed to any expecting mother in order to identify any high GRF.

    Full Text Available Introduction. Although the relationships between alcohol and disorders such as cancer and liver disease have been thoroughly researched, its effects on cardiometabolic health remain controversial. Therefore, the objective of this study was to assess the association between alcohol consumption, the Metabolic Syndrome (MS, and its components in our locality. Materials and Methods. Descriptive, cross-sectional study with randomized, multistaged sampling, which included 2,230 subjects of both genders. Two previously determined population-specific alcohol consumption pattern classifications were utilized in each gender: daily intake quartiles and conglomerates yielded by cluster analysis. MS was defined according to the 2009 consensus criteria. Association was evaluated through various multiple logistic regression models. Results. In univariate analysis (daily intake quartiles, only hypertriacylglyceridemia was associated with alcohol consumption in both genders. In multivariate analysis, daily alcohol intake ≤3.8 g/day was associated with lower risk of hypertriacylglyceridemia in females (OR = 0.29, CI 95%: 0.09–0.86; p=0.03. Among men, subjects consuming 28.41–47.33 g/day had significantly increased risk of MS, hyperglycemia, high blood pressure, hypertriacylglyceridemia, and elevated waist circumference. Conclusions. The relationship between drinking, MS, and its components is complex and not directly proportional. Categorization by daily alcohol intake quartiles appears to be the most efficient method for quantitative assessment of alcohol consumption in our region.

    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

    The Boconó fault is a strike-slip fault lying between the North Andean Block and the South American plate which has triggered at least five Mw > 7 historical earthquakes in Venezuela. The North Andean Block is currently moving toward NNE with respect to a stable South American plate. This relative displacement at 12 mm yr-1 in Venezuela (within the Maracaibo Block) was measured by geodesy, but until now the distribution and rates of Quaternary deformation have remained partially unclear. We used two alluvial fans offset by the Boconó fault (Yaracuy Valley) to quantify slip rates, by combining 10Be cosmogenic dating with measurements of tectonic displacements on high-resolution satellite images (Pleiades). Based upon a fan dated at >79 ka and offset by 1350-1580 m and a second fan dated at 120-273 ka and offset by 1236-1500 m, we obtained two Pleistocene rates of 5.0-11.2 and <20.0 mm yr-1, consistent with the regional geodesy. This indicates that the Boconó fault in the Yaracuy Valley accommodates 40 to 100% of the deformation between the South American plate and the Maracaibo Block. As no aseismic deformation was shown by interferometric synthetic aperture radar analysis, we assume that the fault is locked since the 1812 event. This implies that there is a slip deficit in the Yaracuy Valley since the last earthquake ranging from 1 to 4 m, corresponding to a Mw 7-7.6 earthquake. This magnitude is comparable to the 1812 earthquake and to other historical events along the Boconó fault.

    Interest for apheresis activity has been growing in Venezuela. In 1976 there were only a few devices; in 2003, 80 apheresis machines performed 27,675 donor apheresis procedures and 547 therapeutic procedures countrywide. 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.

    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

    Drug-induced liver injury (DILI) is an important cause of morbidity and mortality worldwide, with varied geographical differences. The aim of this prospective, descriptive, cross-sectional study was to identify and characterize cases of DILI in a hospital of Zulia state, Venezuela. Thirteen patients with a presumptive diagnosis of DILI attended by the Department of Gastroenterology, Hospital Universitario, Zulia state, Venezuela, from December-2012 to December-2013 were studied. Ibuprofen (n = 3; 23.1%), acetaminophen (n = 3; 23.1), isoniazid (n = 2; 15.4%) and Herbalife products (n = 2; 15.4%) were the main drugs involved with DILI. Acetaminophen and ibuprofen showed a mixed pattern of liver injury (n = 3; 23.1%) and isoniazid presented a hepatocellular pattern (n = 2; 15.4%). The CIOMS/RUCAMS allowed the identification of possible (n = 7; 53.9%), probable (n = 4; 30.8%) and highly-probable cases (n = 2; 15.4%) of DILI. Amoxicillin/clavulanate, isoniazid, isotretinoin, methotrexate and Herbalife nutritional products were implicated as highly-probable and probable agents. The highest percentage of DILI corresponded to mild cases that recovered after the discontinuation of the agent involved (n = 9; 69.3%). The consumption of Herbalife botanical products is associated with probable causality and fatality (n = 1; 7.7%). In conclusion, the frequency of DILI cases controlled by the Department of Gastroenterology of the Hospital Universitario of Maracaibo was low, being ibuprofen, acetaminophen, isoniazid and products Herbalife the products most commonly involved. It is recommended to continue with the prospective registration of cases, with an extended follow up monitoring period and to facilitate the incorporation of other hospitals in the Zulia State and Venezuela.

    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

    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

    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.

    87Sr/86Sr ratios, δ13C, and δ18O determinations performed on 30 bulk carbonate rocks are presented to constrain the isotope characteristics regarding Oceanic Anoxic Event 3 in the La Luna Formation, Maracaibo Basin. The samples were collected along a 22 m profile in San Miguel region (Merida State, Venezuela). The exhibited 87Sr/86Sr ratios are between 0.707659, at the base, and 0.707733 at the top of studied section, corresponding estimated younger numerical ages than the inferred ages dated as Santonian (85.8-83.5 Ma) based on occurrence of Dicarinella asymetrica. The obtained 87Sr/86Sr ratios are certainly higher than expected for Santonian sea Sr and they are attributed to regular riverine strontium fluxes in the restricted (gulf-like) Maracaibo Basin. The values of δ18O data between -3.76‰ and -11.76‰ are distributed in two distinct clusters in a same way and coherent as for δ13C data which are in a range between -1.75‰ and -13.87‰. One of the clusters δ13C = -2.5 ± 1.0‰ and δ18O = -10.0 ± 1.5‰), illustrate the homogeneous marine deposition under tropical conditions, while the other, more variable, probably could reflect the cyclicity of temporally changes in Pacific versus Atlantic Ocean circulation with cooling water or cooling trend climate. These δ13C values around -2.5 ± 1.0‰ do not fit with the significant carbon isotope excursion as expected for the oceanic anoxic event (OAE) and support the work hypothesis that Coniacian-Santonian anoxic event (denominate as OAE3) is not a global one.

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

  19. 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

METHODS: Database records from the National Program for MS were searched for patients with an established diagnosis of MS whose first symptoms appeared before age 18. 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.

    1992-07-01

    The purpose of this project is to develop and test improved kinetic models of petroleum generation and cracking, pore pressure buildup, and fluid expulsion. The work was performed jointly between Lawrence Livermore National Laboratory and Research Organization of the Venezuelan National Petroleum Company under Annex 12 of an agreement between DOE and the Venezuelan Ministry of Energy and Mines. Laboratory experiments were conducted at both LLNL and INTEVEP to obtain the reaction rate and product composition information needed to develop chemical kinetic models. Experiments at INTEVEP included hydrous pyrolysis and characterization of oils by gas and liquid chromatography. Experiments at LLNL included programmed pyrolysis in open and self-purging reactors, sometimes including on-line gas analysis by tandem mass spectrometry, and characterization of oils by gas chromatography and nuclear magnetic resonance. The PMOD code was used to develop a detailed pyrolysis mechanism from the extensive laboratory data. This mechanism is able to predict yield of bitumen, oil, and gas as a function of time and temperature for such diverse laboratory conditions as hydrous pyrolysis and rapid, programmed, open pyrolysis. PMOD calculations were compared to geologic observations for 22 wells in the Maracaibo basin. When permeability parameters are chosen to match calculated pore pressures with measured present day values, the PMOD calculations indicate that organic maturation reactions contribute a significant fraction of the overpressure during oil generation and early oil cracking. Calculations agreed with observed geochemical maturity parameters of the source rock. 37 refs., 64 figs., 20 tabs.

    Full Text Available Based on LANDSAT ETM and Digital Elevation Model (DEM data derived by the Shuttle Radar Topography Mission (SRTM, 2000 of the coastal areas of Northern Venezuela were investigated in order to detect traces of earlier tsunami events. Digital image processing methods used to enhance LANDSAT ETM imageries and to produce morphometric maps (such as hillshade, slope, minimum and maximum curvature maps based on the SRTM DEM data contribute to the detection of morphologic traces that might be related to catastrophic tsunami events. These maps combined with various geodata such as seismotectonic data in a GIS environment allow the delineation of coastal regions with potential tsunami risk. The LANDSAT ETM imageries merged with digitally processed and enhanced SRTM data clearly indicate areas that might be prone by flooding in case of catastrophic tsunami events.

    Full Text Available Durante los inicios de la fundación republicana y su posterior desarrollo, la instrucción pública y la ciudadanía fueron ordenadas desde el ideario liberal ilustrado. Para explicar su transcurrir histórico en Venezuela, durante las primeras décadas del siglo diecinueve e inicios del veinte, el artículo se propone demostrar que fueron decisivos para el objetivo político de instituir el orden civilizatorio desde la enseñanza primaria, mediante métodos de enseñanza y prácticas pedagógicas. La primera parte, ilustra sobre los principios doctrinarios de la filosofía liberal-ilustrada, en cuanto a ciudadanía y obligatoriedad escolar del Estado. En la segunda, su aplicación en las constituciones fundacionales, propuestas educativas y primeras reglamentaciones escolares en tiempos republicanos colombianos. La tercera, trata del sistema de enseñanza mutua en escuelas primarias de Venezuela, reglamentaciones y sus resultados para mediados del siglo diecinueve, a partir de la experiencia educativa en Maracaibo, capital provincial y de cantón. Finaliza el estudio, con nuevos decretos de instrucción pública para consolidar el Estado-nación liberal y centralizado, orientado a la ciudadanía nacionalista para la unidad nacional dentro del orden para el progreso. Se concluye que la civilidad y los saberes utilitarios, correlativos con los rituales patrióticos, fueron constitutivos de la instrucción pública primaria en Venezuela.

    Virus isolate T217L was obtained from a diseased tomato (Solanum lycopersicum) plant showing leaf deformation and chlorotic mottle symptoms near Maracaibo in the state of Zulia, Venezuela. Full-length DNA-A and DNA-B molecules of T217L were cloned and sequenced. The genome organization of T217L was identical to the bipartite genomes of other begomoviruses described from the Americas. Characteristic disease symptoms were reproduced in S. lycopersicum and Capsicum annum plants inoculated using the cloned viral DNA-A and DNA-B components, confirming disease aetiology. A sequence analysis of DNA-A showed that the T217L isolate has the highest sequence identity (84%) with sida yellow mosaic Yucatan virus (SiYMYuV), sida golden mosaic Honduras virus (SiGMHV) and bean dwarf mosaic virus (BDMV) isolates. This is less than the 89% identity in the DNA-A component that has been defined as the threshold value for the demarcation of species in the genus Begomovirus. The molecular data show that isolate T217L belongs to a novel tentative begomovirus species, for which the name tomato chlorotic leaf distortion virus is proposed. TCLDV was also detected in symptomatic C. chinense plants growing near the T217L-infected plant.

    Differential identification of Entamoeba histolytica and Entamoeba dispar is essential for both appropriate patient treatment and epidemiological purposes. To determine the prevalence of these amoeba infections in Santa Rosa de Agua (Maracaibo, Zulia State, Venezuela), a PCR assay using specific primers for each species was standardized and applied. 204 stool samples were analyzed through direct microscopic examination with SSF (0.85%) and lugol, formol-ether concentration, and PCR. Under direct microscopy, 42 individuals (20.58%) presented the E. histolytica/E. dispar complex. Meanwhile PCR showed 47 positive cases for these amoebas: 22 E. histolytica (10.78%), 16 E. dispar (7.84%), and 9 (4.41%) mixed infections. There was no significant difference in the presence of E. histolytica and/or E. dispar according to either gender or age. There were no cases of these amoebas in children under 2 years of age. Observed frequency of E. histolytica (31/204) shows the endemic nature of amoeba infection in this community.

    Full Text Available Con el objetivo de contribuir a discernir la compleja problemática de la pobreza y de sus posibles salidas, en este trabajo se discuten algunas razones que explicarían la continuidad del estilo asistencial compensatorio focalizado, propio de la política social neoliberal, en la actual estrategia venezolana de atención a la pobreza, pese a que el discurso del presente gobierno se opone frontalmente a dicho modelo. Destacan, entre otros, dos factores básicos: 1 la vigencia de los mecanismos psicológicos del rentismo, manifiesto en la cultura clientelar aún internalizada en el venezolano, tanto en los ciudadanos como en los gobernantes, a pesar de los cambios de la coyuntura económica y sociopolítica del país, y 2 la importancia político-estratégica del asistencialismo en función del objetivo prioritario, no declarado, de mantener una relativa paz social, legitimidad política, estabilidad del gobierno y del régimen democrático. Se señalan riesgos potenciales del asistencialismo y se bosquejan algunos de los prerrequisitos que hoy exige el enfrentamiento a la pobreza en Venezuela.

    Full Text Available The author reviews the malaria research program in Sucre State, Venezuela, taking an ecosystem approach. The goal was to determine which methods could have been introduced at the onset that would have made the study more ecological and interdisciplinary. Neither an ecosystem approach nor integrated disease control were in place at the time of the study. This study began to introduce an ecosystem approach when two contrasting ecosystems in Sucre State were selected for study and vector control methods were implemented based on research results. The need to have a health policy in place with an eco-health approach is crucial to the success of research and control. The review suggests that sustainability is low when not all the stakeholders are involved in the design and implementation of the research and control strategy development. The lack of community involvement makes sustainability doubtful. The author concludes that there were two interdependent challenges for malaria control: development of an ecosystem approach for malaria research and control, and the implementation of an integrated disease control strategy, with malaria as one of the important health issues.O autor faz uma revisão do programa de pesquisa sobre malária no Estado de Sucre, Venezuela, à luz de uma abordagem ecossistêmica.

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

    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.

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

    2015-01-01

    We have combined surface wave tomography with Ps and Sp receiver-function images based on common-conversion-point (CCP) stacking to study the upper mantle velocity structure, particularly the lithosphere-asthenosphere boundary (LAB), beneath eastern and central Venezuela. Rayleigh phase velocities in the frequency range of 0.01-0.05 Hz (20-100 s in period) were measured using the two-plane-wave method and finite-frequency kernels, and then inverted on a 0.5° × 0.5° grid. The phase velocity dispersion data at grid points were inverted for 1D shear velocity profiles using initial crust-mantle velocity models constructed from previous studies. The 3D velocity model and receiver-function images were interpreted jointly to determine the depth of the LAB and other upper mantle features. The tomographic images revealed two high velocity anomalies extending to more than ∼200 km depth. One corresponds to the top of the subducting Atlantic plate beneath the Serrania del Interior. The other anomaly is a highly localized feature beneath the Maturin Basin. The LAB depth varies significantly in the study region: It is located at ∼110 km depth beneath the Guayana Shield, and reaches ∼130 km at the northern edge of the Maturin Basin, which might be related to the downward flexural bending due to thrust loading of the Caribbean plate and pull from the subducting Atlantic plate. Immediately to the west, the lithosphere is thin (∼50-60 km) along the NE-SW trending Espino Graben from the Cariaco basin to the Orinoco River at the northern edge of the craton. The LAB in this region is the top of a pronounced low velocity zone. Westward, the lithosphere deepens to ∼80 km depth beneath the Barinas Apure Basin, and to ∼90 km beneath the Neogene Merida Andes and Maracaibo block. Both upper mantle velocity structure and lithosphere thickness correlate well with surface geology and are consistent with northern South American tectonics.

Multiple logistic regression models were utilized for analyzing factors associated with elevated serum Lp(a levels and MS. Total cholesterol and LDL-C were corrected according to Lp(a-Cholesterol when necessary. Results. No differences were found in Lp(a values between genders; P=0,292. The association between MS and the classification of Lp(a was statistically significant (χ2=28.33; P<0,0001, with greater levels in subjects with this diagnosis. In the univariate analysis, subjects with each of the separate diagnostic criteria showed higher serum Lp(a concentrations, except for hyperglycemia. Conclusions. Lp(a values exhibit important variations regarding MS and each of its components. Impaired fasting glucose appeared as a protecting factor against elevated Lp(a concentrations, whereas its association with LDL-C and hs-CRP suggests a potential pro-inflammatory role.

    Large populations live on or near alluvial fans in locations such as Los Angeles, California, Salt Lake City, Utah, Denver, Colorado, and lesser known areas such as Sarno, Italy, and Vargas, Venezuela. Debris flows and flash floods occur episodically in these alluvial fan environments, and place many communities at high risk during intense and prolonged rainfall. In December 1999, rainstorms induced thousands of landslides along the Cordillera de la Costa, Vargas, Venezuela. Rainfall accumulation of 293 mm during the first 2 weeks of December was followed by an additional 911 mm of rainfall on December 14 through 16. Debris flows and floods inundated coastal communities resulting in a catastrophic death toll of as many as 30,000 people. Flash floods and debris flows caused severe property destruction on alluvial fans at the mouths of the coastal mountain drainage network. In time scales spanning thousands of years, the alluvial fans along this Caribbean coastline are dynamic zones of high geomorphic activity. Because most of the coastal zone in Vargas consists of steep mountain fronts that rise abruptly from the Caribbean Sea, the alluvial fans provide practically the only flat areas upon which to build. Rebuilding and reoccupation of these areas requires careful determination of hazard zones to avoid future loss of life and property.

    Full Text Available Las especies del género Callinectes sostienen pesquerías importantes en varias partes del mundo. En el occidente de Venezuela, Callinectes sapidus es capturado con palangre y sostiene una pesquería artesanal importante en el Lago de Maracaibo; mientras que en la Isla de Margarita, Callinectes danae es capturado con nasa en zonas cercanas a lagunas costeras y su pesca está limitada por la oferta y la demanda. Estos recursos son de considerable importancia económica entre los crustáceos comestibles; sin embargo, pocos estudios han sido reportados sobre la dinámica poblacional y potencialidad pesquera en ambientes costeros de Venezuela que contribuyan a la toma de decisiones en la administración pesquera. En este documento se presenta información de los parámetros de crecimiento del cangrejo Callinectes danae Smith, 1869, con el fin de obtener un conocimiento detallado del patrón de crecimiento y lograr estimaciones más precisas sobre el tamaño de la población y su disponibilidad para la explotación. Se analizó una muestra constituida por 3 623 ejemplares capturados con nasa cangrejera por la flota artesanal, entre octubre 2007 y septiembre 2008. Se estableció la relación longitud-peso y se estimaron los parámetros de crecimiento de las curvas en longitud y peso del modelo de von Bertalanffy. La proporción sexual global mostró que no existe diferencia significativa entre machos y hembras (χ2=0.04, p>0.05.

    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.

    2015-09-01

    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?

  13. Effects of Caribbean oceanic plateau shallow subduction on topographic uplift and exhumation of the northwestern Maracaibo block, Colombia

    Sanchez, J.; Mann, P.

    2013-12-01

    The Maracaibo block in the northwestern South America is a triangular lithotectonic terrane bounded on its western edge by the Santa Marta-Bucaramanga left-lateral strike-slip fault and the Oca-Ancon right-lateral strike-slip fault on its northern edge. These faults bound two isolated Andean ranges within the Maracaibo block: the Sierra de Santa Marta massif (SSM) in the east whose highest point is 5700 m ASL, and the Serrania del Perija (SP) to the west, whose highest point is 3600 m ASL. The two ranges are separated by an elongate, NNE-trending sedimentary basin, the Cesar-Rancheria basin (CRB). Previous thermochronological studies in the region have shown three discrete exhumation pulses from Paleocene to Miocene that are attributed to various collisional and strike events along the Caribbean margin. However the tectonic origin of the late Neogene deformation that produced the isolated, high topography of the SSM and SP has remained unclear. To establish patterns of recent uplift and associate them with a specific tectonic mechanism affecting the area, we integrated the following results: 1) analysis of stream profiles using channel normalized steepness indices and identification of slope-break knickpoints as indicators of rock uplift; 2) integration of observations from geological maps; 3) interpretation of 2D onland seismic profiles; 4) analysis of published thermochronological data; and 5) analysis of 1D/2D basin model based on well subsidence analysis from the CRB. Our results from the extraction of 550 long stream profiles from different watersheds for the SSM and SP reveal: 1) undisturbed profiles at western flank of the northern SP characterized by a few vertical-step knickpoints associated with lithology changes; in contrast the eastern flank of the northern SP shows slope-break knickpoints and changes in steepness indices increasing by a factor of ~2, all indicative of active fault control affecting this area; 2) disturbed profiles in the elevated

    1985-01-01

    Postulated stages of orogeny in a continental crustal setting are:- 1. Stresses of plate convergence lead to block uplift and complementary basin subsidence. The basin fills with 12-14 km of illite-rich flysch (1km/3Ma). This about doubles the thickness of K-rich sial. 2. In situ heating of the flysch by radioactive decay provides a thermal gradient of c.35/sup 0/C/km and it is metamorphosed (pre-deformation) to greenschists facies. 3. After maximum crustal subsidence continued compression results in updoming of crust and overlying flysch. Cannibalism of flysch, cooling and mild subsidence follow; autometamorphism declines. 4. Thin deltaic-marine deposits complete basin fill over the meta-flysch. The unconformity (a span of only 5-10 Ma) is of minor import. 5. Resetting of the thermal profile of the depressed crust lags far behind that in the flysch. Parallels to the above in the Maracalbo basin fill are: -thickness (approx.11km), nature (flysch abounds), rate of deposition (c.1km/3-4Ma), thermal gradient (c.33/sup 0/C/km) and overall tesselar shape. Presence of impermeable strata in the Maracaibo Basin suggests that large-scale fluid convection is inhibited; conductive models of heat transfer can be used. Computer modeling suggests that radiogenic heat, augmented by exothermic oxidation of organic matter, and with a normal mantle heat flow will explain the autometamorphism of the flysch. Alternative orogenic models invoking pull-apart basins do not explain the great thickness of sediments and absence of volcanic activity.

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

    Full Text Available Los debates sobre la democracia en la Venezuela de hoy carecen de una definición común sobre el tema, sobre cómo estudiarlo, e incluso respecto a qué es democracia. El régimen ha sido descrito de muchas formas: democracia participativa, híbrido, mixto, personalista, populista, iliberal, autoritarismo competitivo. El objetivo de este trabajo es determinar el nivel de calidad de la democracia en Venezuela, en el marco de una concepción procedimental de la democracia. La evaluación empírica de cinco dimensiones de calidad de la democracia (decisión electoral, participación, respuesta a la voluntad popular, rendición de cuentas y soberanía revela un nivel bajo en conjunto, con escasa variación entre 2005 y 2010. Los escenarios posibles luego de las elecciones de 2012 incluyen: reforzamiento de las tendencias autoritarias, militarización abierta, liberalización política con fortalecimiento institucional, o volatilidad duradera con conflicto polarizado y debilidad institucional. La salud del presidente Chávez afectará estos escenarios, dado su carácter de factor central unificador de su movimiento y del régimen.Discussions of democracy in contemporary Venezuela lack a settled definition of the subject, how to study it, or indeed of what counts as «democracy» in the first place.

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

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

    A literature review of four in situ combustion projects: in Miga, Tia Juana, Melones and Morichal fields in Venezuela was made, and a summary of these projects is presented. Reservoir description and project performance data were analyzed. The behavior of the four in situ combustion field tests can be summarized as follows: The problems most often encountered were corrosion and high temperature producing wells. The direction in which the burning front moved was guided essentially by reservoir characteristics. The produced oil was upgraded by about 4{degrees} API, and viscosity was substantially reduced. For Mirochal and Miga fields, the analyses of available information from the combustion projects indicated that the process has been successful in the affected region. Conclusions from this review indicate that the two most frequent problems encountered were operational problems in producing wells and the direction of the burning front. The heterogeneous nature of the sands probably resulted in the burning front moving in a preferential direction, hence reducing areal sweep efficiency.

    Enterobius vermicularis is a nematode with a peculiar biological cycle, thus requiring a special diagnostic technique. In order to determine the prevalence of E. vermicularis infection among schoolchildren in Ciudad Bolívar, Venezuela, 282 children aged 5-14 years old were evaluated between november 1995 and august 1996 by the Graham technique (three perianal swabs with adhesive cellulose tape). The prevalence of enterobiasis in the studied children was estimated 19.1% (54/282). There was no difference between sexes (P > 0.05), but there was a difference between ages (x2 = 13.8; 1.g. = 4), being the infection more frequent between 5 and 8 years. Symptoms were observed in 90.7% of the schoolchildren. Anal pruritus was the most common clinical finding (81.6%). Other less frequent manifestations were enuresis (28.6%) and vulvitis in girls (26.1%). This intestinal parasitosis occurs with high frequency among schoolchildren in Ciudad Bolívar with characteristic and identifiable symptoms in most cases. The Graham method must be used for its diagnosis. This test is not routinely performed in our laboratories unless specifically requested by the attending physician.

    Full Text Available Este trabajo estudia la influencia de los diferentes factores determinantes de los roles que tienen las filiales dentro de las empresas multinacionales, a través de la ponderación del comportamiento de factores del contexto de unas filiales sometidas a un entorno adverso. Se utiliza la metodología de estudio de casos en diecisiete filiales localizadas en Venezuela de diversos sectores. El estudio comprueba que la adversidad del entorno es uno de los factores contextuales que mayor influencia ejerce en la determinación de los roles de las filiales, induciendo a una devaluación de los roles de las mismas. El impacto de los determinantes varía dependiendo del tipo de filial: aquellas que realizan pocas actividades de valor agregado, usualmente de mercadeo y ventas, dependen más de la asignación de la matriz, mientras que las que incorporan un mayor número de actividades de la cadena de valor, integran otros determinantes como la adversidad del entorno y la iniciativa desarrollada por la propia filial.

    Mosquitoes (Diptera: Culicidae) are holometabolous insects with aquatic immature stages, which use a broad variety of larval habitats, from ground water bodies to Phytothelmata (water deposits in plants) and artificial deposits. The availability of breeding sites often determines the upper limits of mosquito ranges. We built a database with 9,607 records with 432 localities, 19 genera and 254 species. The Andean mountains have 77% of the highest mosquito records including Aedes euris with record at 3,133 m, followed by three species of Anopheles--subgenera Kerteszia--with the upper limit of 2,680 m. Wyeomyia bicornis and Culex daumastocampa at 2,550 m were the highest records in the Central-Coastal cordillera, while the highest record in Pantepui was Wyeomyia zinzala at 2,252 m. The species associated with phytothelmata (Bromeliaceae and Sarraceniaceae) represent 60% of the records. The upper limits of Culex quinquefasciatus and Anopheles (Kerteszia) species could represent the theoretical limit for transmission of filariasis or arboviruses, by Culex, and malaria by Anopheles (Kerteszia) in Venezuela. Similarly, a vector of Dengue, Aedes aegypti, has not been not recorded above 2,000 m.

    2014-03-01

    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.

Para el logro del referido objetivo se desarrolló una investigación documental que permitió la extracción de indicadores o rasgos teóricos del desarrollo local y se comprobó la presencia de tales rasgos en realidad municipal estudiada, mediante la aplicación de un cuestionario semi-estructurado a los directivos responsables de la gestión de políticas en el municipio y el análisis de documentos de gestión. Los resultados muestran la identificación de informalidad y poca sistematización en las PI, autonomía en su generación, intencionalidad hacia la modernización de la gestión pública, prioridad hacia las áreas de organización, promoción y automatización de información, al igual que un rol tradicional de atención a necesidades intrainstitucionales con poca presencia de rasgos como la consideración de intereses de la comunidad, incremento de la capacidad innovadora, generación de servicios para las comunidades, entre otros. Se concluye que el Municipio Maracaibo transita un camino con obstáculos hacia su desarrollo integral, en virtud de la ausencia de rasgos de desarrollo significativos en las PI formuladas y ejecutadas por los entes municipales competentes.

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

  4. Assessing Whether Oil Dependency in Venezuela Contributes to National Instability

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

    2014-01-01

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

    The complete sequences of isolates of two new bipartite begomoviruses (genus Begomovirus, family Geminiviridae) found infecting weeds in Venezuela are provided. The names proposed for these new begomoviruses are "Datura leaf distortion virus" (DLDV), isolated from a Datura stramonium L. (family Solanaceae) plant, and "Dalechampia chlorotic mosaic virus" (DCMV), isolated from infected Dalechampia sp. (family Euphorbiaceae) and Boerhavia diffusa L. (family Nyctaginaceae) plants. Phylogenetic analysis showed that these new begomoviruses segregated in two distinct clades of New World begomoviruses. To our knowledge, this is the first record of a begomovirus infecting Dalechampia sp. plants. Also, this is the first report of a begomovirus infecting Boerhavia spp. and Datura spp. in Venezuela.

A través de la etnografía y entrevistas, se concluye que MBA proporcionó acceso a la atención médica y logró obtener apoyo popular a consecuencia de: movimientos sociales de los pobres; cooperación entre trabajadores comunitarios, residentes, profesionales de salud y funcionarios públicos; la integración de la atención médica con programas sociales y económicos; la ubicación de médicos como residentes en barrios pobres; interacciones positivas y equitativas médico-paciente; el papel clave de los Comités de Salud; y el impacto de la hostilidad de la prensa, un segmento grande de los médicos venezolanos y la oposición en transformar a la salud en un tema político esencial. Todo esto nos sugiere que el Estado puede confrontar las inequidades de salud cuando se unen perspectivas teóricas de la medicina social y la epidemiología crítica con los saberes populares dentro de las comunidades afectadas. Estructuras institucionales flexibles, no burocráticas y creativas aumentan la efectividad de las intervenciones.

    Isla de Toas is an island on the north of the Maracaibo Lake, it is known in the scientific community, for the high frequency of sickle cell disease, in a population with caucasoid phenotype. The purpose of the present work was to determine the frequency of sickle cell anemia in the population of Cuatro Bocas, situated 35 km from the southwest of Isla de Toas. The town is the center of confluence of a rural population constituted mainly of farmers. The sample consisted of 870 persons of both sexes, aged from 8 months to 66 years. The presence of the sickling phenomenon was determined in all the individuals, and hemoglobin electrophoresis in agarose was performed in all the positive samples. The following results were obtained: fifty-six cases (6.4%), showed drepanocytic changes, and forty-six of them were haemoglobin A/S, 8 were S/S and 2 were S/C. The higher frequency of hemoglobin S was in adolescents and adults. The family backgrounds suggest an insular origin of the sickle cell gene. About 75% of the affected population was ignorant of this condition. The hemoglobin values were lower in the individuals with the sickle cell disease (p < 0.05), than in the normal persons. Iron deficiency in adolescents was suspected because or their low hemoglobin values. The results indicate that the sickle cell gen is expanding to the nearest communities of the Mara county. It is important to consider that the findings of the present work should serve as an alert to the Public Health authorities, and that education of the population is important in order to prevent the spreading of the disease.

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.

    2006-01-01

    This article looks at household and individual poverty rates in Venezuela over the past seven years. For more than a year, the statement that poverty in Venezuela has increased under the government of President Hugo Chávez has appeared in scores of major newspapers, on major television and radio programs, and even in publications devoted to foreign policy. There are no data to support such statements, and in fact the available data show a decline in poverty for both individuals and households over the seven-year period: the percentage of people in poverty declined from 50 percent in the first quarter of 1999 to 43.7 percent in 2005. Further, there is no evidence to suggest any change in the methodology for measuring poverty during this period, as has been alleged in a number of reports. The article also examines briefly the impact of significant changes in non-cash benefits such as free health care, which are not taken into account in the measured poverty rate, on poor people in Venezuela. Finally, the authors look at how the mistakes in reporting on Venezuela's poverty rate were made; an appendix gives examples of mistakes in major media and foreign policy publications.

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

    Oral outbreaks of Chagas disease are increasingly reported in Latin America. The transitory presence of Trypanosoma cruzi parasites within contaminated foods, and the rapid consumption of those foods, precludes precise identification of outbreak origin. We report source attribution for 2 peri-urban oral outbreaks of Chagas disease in Venezuela via high resolution microsatellite typing.

    2011-06-01

    Recent phylogenetic studies based on cytochrome b gene sequence, have determined that the species historically known as Sigmodon hispidus (Rodentia) from South America comprises a species S. hirsutus of paraphyletic origin. The aim of this study was to test the hypothesis that populations from Venezuela, represent the sensu strict form, ancestral haplotypes, and monophyletic subspecieS. For this, 12 individual sequences from three localities of different biogeographic regions in Venezuela were evaluated and sequenced based on cyto b. Additionally, the sequences were used to develop a cladistic analysis and genetic distance calculations, and to compare this information with two individual sequences of Sigmodon specimens available in Genbank. Phylogenetic analyses show that the three populations of S. hirsutus of Venezuela form an ancestral and monophyletic subclade supported by high bootstrap values and significant genetic distance between subclade within the S. hirsutus. Besides, the existence of two lineages suggests two subspecies, S. hirsutus hirsutus from Venezuela, and S. hirsutus mexicanus from Mexico-Central America, but, both species need formal description.

    2012-07-01

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

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

    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

    Mustieles, F.

    1998-02-01

    Full Text Available In intertropical latitudes such as Venezuela with hot humid climates, building envelopes must reduce influence of solar radiation, and in these, roofs and windows must receive special attention. Venezuela is also the country with the highest energy consumption per capita in Iberoamérica, much of which is generated by air conditioning systems in residential buildings, and Maracaibo and the surrounding lake basin have some of the highest temperature and humidity values in Venezuela, which increase energy consumption even more. A bioclimatical house for this climate is proposed. This building incorporates principles from traditional indigenous, colonial and oil company houses in the Maracaibo lake basin to generate a new prototype, called the Fourth House.

    En climas cálidos húmedos como es el caso de grandes regiones de Venezuela, las envolventes deben reducir la influencia de la radiación solar y, por lo tanto, deben recibir atención especial. Venezuela es también el país con más alto consumo energético per capita en Iberoamérica, generado en su mayor parte por el uso de sistemas de aire acondicionado en las edificaciones residenciales. En Maracaibo y en los alrededores del Lago de Maracaibo se registran los valores más altos de temperatura y humedad en Venezuela, lo que incrementa, aún más, el consumo energético de las viviendas de estas regiones. La minimización del impacto de la radiación solar para lograr la reducción del consumo energético con un mayor bienestar térmico ha sido precisamente uno de los objetivos perseguidos con el desarrollo de una nueva vivienda bioclimática para la región del lago de Maracaibo. Esta incorpora principios de las tres viviendas bioclimáticas previas existentes en esa región: el palafito o vivienda tradicional indígena, la vivienda colonial republicana y la vivienda petrolera. Es por ello que esta vivienda ha sido llamada la Cuarta Vivienda.

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

    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.

  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.

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.

    Dengue is a mosquito-borne disease caused by four closely related dengue virus (genus Flavivirus)serotypes (DENV-1–4). The clinical outcomes vary from mild febrile illness to life-threatening haemorrhagic manifestations. DENVs are endemic in the tropics and subtropics globally and currently no specific treatment or vaccines are available. In Venezuela, the American-Asian genotype of DENV-2 is the most prevalent and has been associated with severe disease outcomes.We aimed to follow-up the molecular epidemiology of DENV-2 in Venezuela to investigate if the evolution of the virus has remained the same throughout time or if the same dynamics documented in Brazil (hyperendemic co-circulation) also occurred. The results show that whereas the epidemiology of DENV in several endemic areas is characterized by serotype replacements through time, in Venezuela the American-Asian genotype DENV-2 has evolved into several genetic lineages and has remained in hyperendemic co-circulation with the other serotypes.

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

    Science.gov (United States)

    Eid, Mahmoud; Nahon-Serfaty, Isaac

    2015-01-01

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

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

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

    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).

  2. Great Lakes

    The Great Lakes region, as defined here, includes the Great Lakes and their drainage basins in Minnesota, Wisconsin, Illinois, Indiana, Ohio, Pennsylvania, and New York. The region also includes the portions of Minnesota, Wisconsin, and the 21 northernmost counties of Illinois that lie in the Mississippi River drainage basin, outside the floodplain of the river. The region spans about 9º of latitude and 20º of longitude and lies roughly halfway between the equator and the North Pole in a lowland corridor that extends from the Gulf of Mexico to the Arctic Ocean.The Great Lakes are the most prominent natural feature of the region (Fig. 1). They have a combined surface area of about 245,000 square kilometers and are among the largest, deepest lakes in the world. They are the largest single aggregation of fresh water on the planet (excluding the polar ice caps) and are the only glacial feature on Earth visible from the surface of the moon (The Nature Conservancy 1994a).The Great Lakes moderate the region’s climate, which presently ranges from subarctic in the north to humid continental warm in the south (Fig. 2), reflecting the movement of major weather masses from the north and south (U.S. Department of the Interior 1970; Eichenlaub 1979). The lakes act as heat sinks in summer and heat sources in winter and are major reservoirs that help humidify much of the region. They also create local precipitation belts in areas where air masses are pushed across the lakes by prevailing winds, pick up moisture from the lake surface, and then drop that moisture over land on the other side of the lake. The mean annual frost-free period—a general measure of the growing-season length for plants and some cold-blooded animals—varies from 60 days at higher elevations in the north to 160 days in lakeshore areas in the south. The climate influences the general distribution of wild plants and animals in the region and also influences the activities and distribution of the human

    1953-01-01

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

    Agave cocui (Agavaceae) is a species with broad distribution in arid and semiarid areas of Venezuela and Colombia. Despite of its ecological importance as a source of food for wildlife, and its economic value for production of a spirit drink, studies on the reproductive ecology of the species are relatively rare. In this study, we conducted a one-year evaluation of the flowering and fruiting phenology of A. cocui in the eight representative localities of the species' distribution in Venezuela. Within each study site, we chose an area with a minimum of 50 reproductive individuals and followed their reproductive phenophases with the help of binoculars, using six qualitative cathegories (emerging reproductive stalk, flowers, inmature fruits, mature fruits, bulbils and dry stalk) every two months. Emergence of the reproductive stalk in most of the examined populations began in September (rainy season), although this event delayed two months in a few populations. We detected significant negative correlations between precipitation and the percentage of flowering occurrence in four of the eight populations. Floral resources are available for flower visitors during approximately five months of the year (January-May). In most populations production of flowers initiated in January (dry season), and for Western Venezuela and Andean regions, the flowering main peak occurred in January. Localities from the Central and Eastern Coast exhibited the flowering peak in March, showing a delay of approximately two months with respect to other populations. Beginning of fruit set varied among localities from January to May; however, peak production of mature fruits concentrated in May, and fruit occurrence varied broadly between 5.2 and 85%. Bulbil production was detected in all populations and varied greatly among them (maximum percentage per population: 26.19-92.10%). High flowering synchronicity (Phenophase Overlapping Index: 0.756 and 0.999) was observed among all populations

    Abstract Strains of Caño Delgadito virus (CADV) and Maporal virus (MAPV) were isolated from 25 (8.9%) of the 280 rodents captured on farms in 1997 in western Venezuela. The results of analyses of laboratory and zoographic data indicated that Alston's cotton rat (Sigmodon alstoni) is the principal host of CADV, horizontal virus transmission is the dominant mode of CADV transmission in Alston's cotton rat in nature, a pygmy rice rat (Oligoryzomys sp.) is the principal host of MAPV, and the natural host relationships of CADV and MAPV are highly specific.

    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

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

    Steam injection is a major oil recovery method in Venezuela, with 3 trillion bbl of oil possibly recoverable by this technqiue. Alongside progress in steam injection technology, the development of a series of numerical simulators has been proceeding at an accelerated pace. This work describes 3 of the steam injection simulators developed, and their application to 2 major heavy oil reservoirs. These simulators describe 3-phase, nonisothermal multicomponent flow, consisting of 4, 3, and 2 components, respectively, in 3 dimensions. The implicitness of the simulators increases in the order of decreasing number of components. However, for a variety of problems, the less implicit but more efficient simulators are adequate. The finite difference methods used for each simulator are outlined. These, as well as the computational performance, are compared with the existing simulators. The application of the simulators to 2 major reservoirs in Venezuela-morichal and M/sup -6/ is described and compared. Effects of such factors as spacing, injection rate, and gravity segregation are examined. 14 references.

    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.

  8. Urban movements and disempowerment in Perú and Venezuela

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

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

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

    Full Text Available Quantitative parameters of intestinal helminth species and their potential relations to host characteristics in a population of capybaras (Hydrochoerus hydrochaeris from Venezuela are reported for the first time. The intestines of 40 capybaras were collected during the 1992-annual harvest at Hato El Cedral. Six helminth species were found: 2 cestodes (Monoecocestus macrobursatum, M. hagmanni, 2 nematodes (Viannella hydrochoeri, Protozoophaga obesa, and 2 trematodes (Hippocrepis hippocrepis, Taxorchis schistocotyle. This is the first report for M. macrobursatum in Venezuela. Helminth abundance did not differ between sexes or age classes. Although patterns of distribution for all helminth species were overdispersed, the high prevalence found for all species (over 70% and the high abundance observed for nematodes made it difficult to assess the effect that these helminths may produce on capybaras. Nevertheless, the negative associations found between the body condition of capybaras and helminth intensity for M. macrobursatum and V. hydrochoeri, might be pointing out potential host population regulatory role for these parasites which require further research.

    Breast cancer incidence and mortality rates are of concern among Latin American women, mainly due to the growing prevalence of this disease and the lack of compliance to proper breast cancer screening and treatment. Focusing on Venezuelan women and the challenges and barriers that interact with their health communication, this paper looks into issues surrounding women's breast cancer, such as the challenges and barriers to breast cancer care, the relevant ethics and responsibilities, the right to health, breast cancer risk perception and risk communication, and the media interventions that affect Venezuelan women's perceptions and actions pertaining to this disease. In particular, it describes an action-oriented research project in Venezuela that was conducted over a four-year period of collaborative work among researchers, practitioners, NGOs, patients, journalists, and policymakers. The outcomes include positive indications on more effective interactions between physicians and patients, increasing satisfactions about issues of ethical treatment in providing healthcare services, more sufficient and responsible media coverage of breast cancer healthcare services and information, a widely supported declaration for a national response against breast cancer in Venezuela, and the creation of a code of ethics for the Venezuelan NGO that led the expansion of networking in support of women's breast cancer healthcare.

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.

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

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

  13. The Crustal Structure and Seismicity of Eastern Venezuela

    Science.gov (United States)

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

    2001-12-01

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

Of particular interest is its work in Venezuela where it operates CAVOVEN, a company created in 1982 in which CAVOSA has a 40% share and Venezolana de Cementos belonging to the Venezuelan Mendoza group, holds the remaining 60%. As a result of the research carried out, a feasibility study is now under way on opencast mining a multi-seam deposit of coal with a high content of volatile matter and of a type suitable for sale on the international heat market. This feasibility study was carried out by Estudios y Proyectos Mineros (Mining Studies and Projects) in Spain and British Mining Consultants, an engineering subsidiary of the National Coal Board (UK). 3 tabs.

  1. 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

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

    Science.gov (United States)

    Gulbas, Lauren E

    2013-03-01

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

  5. Potential options to reduce GHG emissions in Venezuela

    Energy Technology Data Exchange (ETDEWEB)

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

    1996-12-31

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

    2011-01-01

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

    2013-10-01

    Enteric Helicobacter species (Helicobacter pullorum, Helicobacter pametensis, Helicobacter canadensis, Helicobacter anseris, and Helicobacter brantae) have been found in birds from temperate latitudes. We evaluated the occurrence of Helicobacter spp. in terrestrial wild birds from Venezuela. A fragment of 16S rRNA gene was amplified by PCR with Helicobacter genus-specific primers. Helicobacter spp. were detected in four of 80 fecal and in three of 42 intestinal tissue samples. Analyses of 16S and 23S rRNA gene sequences confirm for the first time the presence of Helicobacter in tropical terrestrial wild birds. However, the occurrence of Helicobacter was low, suggesting these bacteria may be uncommon in the populations we studied.

  9. Coal in Colombia and Venezuela: Production, transportation and export logistics

    Energy Technology Data Exchange (ETDEWEB)

    Thompson, D. [Coal Export Services International, Inc. (United States)

    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.

  10. Paralytic Shellfish Poisoning (PSP in Margarita Island, Venezuela

    2004-09-01

    Full Text Available A severe outbreak of Paralytic Shellfish Poisoning (PSP occurred in Manzanillo and Guayacán, northwestern coast of Margarita Island, Venezuela, between August and October 1991. A bloom of dinoflagellates including Prorocentrum gracile, Gymnodinium catenatum and Alexandrium tamarense seemed to be responsible for this outbreak. Levels of PSP toxins in mussels (Perna perna exceeded the international safety limit of saxitoxin, 80 µg STX/100 g meat. PSP toxin values varied between 2 548 and 115 µg STX/100 g meat in Manzanillo, and between 1 422 and 86 µg STX/100 g meat in Guayacán. At both locations, the highest levels were detected in August, when 24 patients exhibited typical symptoms of PSP toxicity after consuming cooked mussels (16 required hospitalization. A high pressure liquid chromatographic (HPLC procedure was recently used on the 1991 samples. The major toxin detected in samples of both locations was decarbamoyl saxitoxin (dcSTX, but low concentrations of saxitoxin were also found in Manzanillo samples. Gonyautoxins GTX1, GTX2 and GTX3 were detected only at Guayacán, while in both locations, decarbamoylgonyatouxin (dcGTX2,3 toxins were detected. These findings represent the first time that causative toxins of PSP in Venezuela have been chemically identified, and confirm the presence of dcSTX and dcGTX in mussels from the Caribbean Sea. The presence of dcSTX and dcGTX in shellfish is indicative that Gymnodinium catenatum was a causative organism for outbreak of PSPUn severo brote de intoxicación paralizante por moluscos (PSP en inglés ocurrió en Manzanillo y Guayacán en la costa noroeste de la Isla de Margarita, Venezuela entre agosto y octubre de 1991.

    Full Text Available The eggshell fine structure of five sand fly species from Venezuela belonging to the genus Lutzomyia (L. migonei, L. ovallesi, L. absonodonta, L. gomezi and L. panamensis was examined by scanning electron microscopy. 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.

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

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

    Steam-assisted gravity drainage (SAGD) is one of the most effective enhanced oil recovery (EOR) methods. In Venezuela, a significant amount of heavy oil in place has been mapped, but limited areas have been developed. Suitable EOR methods need to be applied to extend the productive life of these reservoirs and increase their recovery factors. This paper presented and described an evaluation and stepwise optimization process for a steam-assisted gravity drainage (SAGD) project using a representative sector model from a field with fluid and reservoir characteristics from an eastern Venezuela formation. The purpose of the study was to understand the impact of key parameters in the process specific to the selected area and to understand the effects on the recovery factor in these reservoirs, which have previously produced with primary recovery mechanisms. The paper discussed a sensitivity analysis that was performed using thermal simulation. Thermal simulation and pressure-volume-temperature (PVT) analysis were described. Parameters that were analyzed included vertical well spacing, injection steam rate, well flowing pressure, and horizontal length of the well pair. The paper also presented a brief analysis of the effect on oil recovery from the angle of dip in the reservoir and the orientation of the well pair with regard to the direction of dip. A comparison between two- and three- pseudocomponent model results was also provided. The authors recommended that economic analyses should accompany the final optimization sequence, to incorporate financial and technical considerations for the selection design of the SAGD pilot. 7 refs., 12 tabs., 18 figs.

    Austrodiplostomum compactum from Nannopterum brasilianus, and its metacercaria from Geophagus sp. and Oreochromis mossambicus captured (1979) at its type locality Valencia Lake, Venezuela, by the author, is redescribed. The adult is characterized by its large body size, and an oral sucker smaller than the pharynx. The metacercaria has a similar body size as the adult, and the small genital primordia occupy 4.1-7.3% of body length. Experimental infections in chickens with metacercariae of Diplostomulum mordax from brains of Odonthestes bonariensis, captured (2015) at Dique Paso de las Piedras, near Bahia Blanca City, Buenos Aires Province, resulted in 10 adults 5 days post exposure. These adults correspond to A. mordax as described by Drago et al. (2011) and differ from A. compactum in their smaller body size, and an oral sucker larger than the pharynx. The metacercaria has a similar body size as the adult and differs mainly in that the larger genital primordia occupy 11.6-13.8% of body length. The status of earlier published Austrodiplostomum species in the American Continent is discussed in view of available morphological and molecular data. A Lectotype of A. mordax is here designed and A. ostrowskiae is considered as a new synonym of A. compactum.

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

    Attempts to maintain the native lake trout (Salvelinus namaycush) population in Lake Ontario by stocking fry failed and the species was extirpated by the 1950s. Hatchery fish stocked in the 1960s did not live to maturity because of sea lamprey (Petromyzon marinus) predation and incidental commercial harvest. Suppression of sea lampreys began with larvicide treatments of Lake Ontario tributaries in 1971 and was enhanced when the tributaries of Oneida Lake and Lake Erie were treated in the 1980s. Annual stocking of hatchery fish was resumed with the 1972 year class and peaked at about 1.8 million yearlings and 0.3 million fingerlings from the 1985–1990 year classes. Survival of stocked yearlings declined over 50% in the 1980 s and was negatively correlated with the abundance of lake trout > 550 mm long (r = −0.91, P < 0.01, n = 12). A slot length limit imposed by the State of New York for the 1988 fishing season reduced angler harvest. Angler harvest in Canadian waters was 3 times higher in eastern Lake Ontario than in western Lake Ontario. For the 1977–1984 year classes, mean annual survival rate of lake trout age 6 and older was 0.45 (range: 0.35–0.56). In U.S. waters during 1985–1992, the total number of lake trout harvested by anglers was about 2.4 times greater than that killed by sea lampreys. The number of unmarked lake trout < 250 mm long in trawl catches in 1978–1992 was not different from that expected due to loss of marks and failure to apply marks at the hatchery, and suggested that recruitment of naturally-produced fish was nil. However, many of the obstacles which may have impeded lake trout rehabilitation in Lake Ontario during the 1980s are slowly being removed, and there are signs of a general ecosystem recovery. Significant recruitment of naturally produced lake trout by the year 2000, one interim objective of the rehabilitation plan for the Lake, may be achieved.

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

    The ocular manifestations and sequelae of Zika virus infection are not well known. Recently, the World Health Organization changed the declaration of Zika as a public health emergency and designated the viral outbreak and related microcephaly clusters as a long-term program of work. This change indicates the urgent need to evaluate and document ophthalmic manifestations in patients for timely management of this disease. In addition, confirmation whether the public health problem in Brazil extends to other regions in South America is needed. To report the ocular manifestations of congenital Zika syndrome with microcephaly in Colombia and Venezuela. This prospective case series included 43 patients from 2 ophthalmic centers in Colombia and Venezuela who underwent evaluation from October 1, 2015, through June 30, 2016, and were clinically diagnosed with congenital Zika syndrome. Twenty patients were Hispanic; 13, African; 8, white; and 2, Native American. Ophthalmic and systemic evaluations and serologic testing were performed on all infants. Patients underwent external ocular examination and dilated ophthalmoscopy. Serologic testing ruled out toxoplasmosis, rubella, cytomegalovirus, syphilis, and human immunodeficiency virus. Ophthalmic manifestations of congenital Zika syndrome. Of the 43 patients included in this series (28 female and 15 male), the mean (SD) age at examination was 2.1 (1.5) months.

    1983-01-01

    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

    Full Text Available RESUMEN: Partiendo de la afirmación de Levine y Molina (2006, según la cual la calidad de la democracia depende del funcionamiento de los procesos mediante los cuales la población selecciona y controla sus gobernantes, en este trabajo se examina el caso venezolano, haciendo especial énfasis en el análisis de la dinámica electoral del período marcado por la presidencia de Chávez (1999-2006. Dicho examen nos lleva a concluir que el régimen sociopolítico venezolano actual puede ser caracterizado más adecuadamente como un «régimen autoritario electoral», más que como una democracia representativa convencional. Los rasgos autoritarios del gobierno venezolano actual explicarían la baja puntuación obtenida por Venezuela en los índices de Freedom House. Sin embargo, este examen también nos lleva a considerar la pertinencia de los supuestos de la calidad de la democracia en el contexto de un cambio de régimen que explícitamente se aleja de las aspiraciones e ideales que sustentan el concepto, dimensiones e indicadores de la calidad de la democracia propuestos.ABSTRACT: Taking off from the affirmation by Levine and Molina that «the quality of democracy depends on the operation of procedures whereby the population selects and controls its government», this article examines the dynamics of elections during the Presidency of Chávez, (1999-2006. This examination leads to the conclusion that the current regime is better characterized as «an autoritarian electoral regime» than as a conventional representative democracy. This re-definition explains the low scores obtained by Venezuela both in Freedom House. At the same time, this study throws light on the bases of democracy and of definitions of quality of democracy in a regime that explicitly rejects the very ideals and aspirations that underlie the definitions, dimensions and indicators of democracy itself.

    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

Se incorporaron revisiones significativas de la geologia de la Cordillera de la Costa a partir de las nuevas hojas integradas a escala 1:25.000. Toda esta informacion geologico-estructural se sobrepuso a una imagen de relieve sombreado, producida por el procesamiento de los datos de radar interferometrico con 90 m (3 arcosegundos) de resolucion espacial obtenidos por la mision topografica de radar del transbordador espacial (SRTM). Las areas de la base de datos del SRTM carentes de informacion fueron llenadas por medio de la interpolacion de los datos de las celdas adyacentes. Para producir la imagen de relieve sombreado se uso una direccion de iluminacion de 315 deg con un angulo de 65 deg sobre el horizonte. La proyeccion usada en el mapa es conica equidistante, con latitudes de 4 y 9 deg norte como paralelos estandar y una longitud de 66 deg al oeste como meridiano central.

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

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

  19. Intestinal Parasitic Infections among Pregnant Women in Venezuela

    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.

    Most of the anthropometric standards are derived from adult populations but not from older subjects, so their use to evaluate the nutritional status in the elderly may not be the most appropriate. In this sense, the anthropometric characteristics and their relationship to sex and age in a cross-sectional sample of 809 Venezuelan subjects (370 males and 439 females), aged 60 to 102 years old, randomly selected from a elderly institution-alised population were studied. The results indicate that anthropometric variables show different degrees and signs of sexual dimorphism. Males presented higher stature, weight, waist and calf circumferences and higher bone diameters, while females have higher hip and thigh perimeters, and bigger trunk and extremities skinfolds. Independently of the changes observed in these variables with age, the difference spread between the sexes tends to stay and even to increase with age in the height and weight, in hip perimeter and in thigh and calf skinfolds; while, on the contrary, they attenuate in waist perimeter and in triceps, subescapular and suprailiac skinfolds. Males and females appear to be more similar for these variables in the advanced ages. In general, these results could be used as reference elements for similar researches in Venezuela, due to the low number of studies developed in the country in older populations

    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.

    The medium-grade oil reservoirs of the Guafita field, Apure basin, southwestern Venezuela, represent the northeastern extension of the La Yuca-Cano Limon fields of Colombia. A detailed integrated reservoir study is being carried out in Guafita in order to define the geological model and to improve its development plan. The stratigraphic sequence of interest in the southern block of the Guafita field contains approximately 600 ft of sediments of Cretaceous and Oligocene-Miocene ages (Quevedo Member of the Navay and Guafita Formations, respectively). Fifteen prospective intervals, with approximately 150 ft of net oil sand, have been defined within this sequence by detailed correlation in the Colombian fields and four have been defined in the Quevedo Member. Lower delta-plain and delta-front depositional environments have been recognized from core studies in the Tertiary sediments. A combination of both structural and stratigraphic traps controls the hydrocarbon accumulations in the Guafita field, and at least two sealing shale regional markers have been defined. As a preliminary result of the approach of defining reservoir geometry and mapping each major sand body separately, the proven reserves of the Guafita field will decrease by approximately 12%. The possibility of fluid communication with the Colombian fields through the small-displacement riddle faults was established by means of juxtaposition of sand bodies.

    We present our experience on the design and development of a gynaecology and obstetrics graduate residency programme, developed in the Department of Obstetrics and Gynecology at the Dr Adolfo Prince Lara Hospital, Puerto Cabello, Venezuela, in which medical specialists and residents participate synergistically. From January to September 1993, curricular activities were planned and students selected. The programme started in October 1993, with six residents for a three-year programme. Courses were given by medical specialists from the Department. In addition to a Programme Coordinator, there is also a Residents' Coordinator, appointed for a two-month term of office; specific functions were assigned for residents occupying this position. All the programmed activities for three years were accomplished, including lectures and rotations, with an important record of surgical interventions. In our grade system, residents got an average of 18 over a maximum of 20 points. Residents also participated as speakers in workshops, special courses and national medicinal meetings, in which they presented a total of nine papers. Activities were evaluated bimonthly in meetings with students and each semester by the Graduate Committee. The first class graduated in September 1996. Results suggest that resident participation in graduate programmes is an important part of their education. PMID:9538482

    Full Text Available Venezuela pese a los innumerables dotes naturales no ha podido alcanzar el anhelado desarrollo, tampoco el bienestar de todos sus habitantes, en parte porque sus acciones y prácticas económicas no se han fundamentado en el desarrollo sustentable, su comercio exterior se limita a la exportación de materias primas básicas sin mucho valor agregado cuya explotación intensiva incrementa la vulnerabilidad ecológica irreversible. En el presente trabajo se analiza la economía venezolana en el marco del desarrollo sustentable, vinculando su participación en el comercio exterior con el desarrollo sustentable. Se recomienda la urgente reducción de la dependencia petrolera, la diversificación económica y de exportaciones, para participar en el comercio internacional de forma dinámica con productos de alto valor agregado. El reto son los procesos de liberalización comercial y mundialización que promueva la sustentabilidad ecológica y el desarrollo humano equitativo, integrando mundialmente las políticas ecológicas y comerciales, dado que el comercio internacional no necesariamente eleva la calidad de vida y la salud del planeta, por el contrario, todo depende del uso eficiente de los recursos para crear riquezas en concordancia con la protección del medio ambiente.

    1999-11-01

    We stratified the risk of malaria transmission (Plasmodium vivax) in 35 villages along a coastal range in northeastern Venezuela (51 km2) where the main vector is the mosquito Anopheles aquasalis. After 20 years without local malaria transmission, reinfection of the entire area occurred from May to December 1985 by local (continuous) and jump (discontinuous) dispersal. Epidemiologic, environmental, and vector variables were investigated with the aid of a Geographic Information System. Risk factors for malaria transmission were human population density, proximity to pre-adult mosquito habitats (< 500 m), and the number of pre-adult habitats nearby. Most inhabitants, immature mosquito habitats, and malaria cases were located at low elevations and on gentle slopes. High prevalence of malaria during the dry seasons was associated with the presence of permanent bodies of water containing An. aquasalis. Occurrence of a La Niña event in 1988 (wet and cool phase of the El Niño Southern Oscillation) triggered malaria transmission to unusually high levels, consolidating infection in the area, and rendering traditional control efforts useless. We recommend tracking malaria persistence per village and associated risk factors as methods to reduce the cost of malaria control programs.

    Full Text Available La globalización, al mismo tiempo que introduce tendencias hacia la homogeneidad económica, impulsa la “economía difusa” a través de procesos de descentralización y reubicación de las estructuras industriales en asentamientos territoriales como las regiones fronterizas. Ha sido señalado el peligro de tales estrategias para la integridad y futuro de los Estados nacionales. En este artículo se analiza, en la perspectiva del proceso histórico, el caso específico de la región fronteriza que comparten Venezuela y Colombia, compuesta por los Estados Zulia y Táchira y el Departamento de Santander, respectivamente. La categoría “región histórica” sirve de marco teórico-metodológico para la comprensión del problema originado por el actual juego dialéctico de “Globalización-Estado nacional-Región” con el objeto de sustentar posibles propuestas de carácter sociopolítico.

    Soil, waste rock and mud from mercury-gold amalgamation mining areas of El Callao (Venezuela) are highly enriched in Hg (0.5-500 microg g(-1)) relative to natural background concentrations (mining districts (>100,000 ng m(-2) h(-1)). The results from this study also show that Hg emissions from the soil are influenced by solar radiation, soil temperature and soil Hg concentration. Our data suggest that solar radiation may be the dominant factor affecting Hg degrees emission since the major species of mercury in polluted soil is Hg degrees (85-97% of total Hg). The simple release of Hg degrees vapor is probably the dominant process occurring with incident light in the field. The apparent activation energy for mercury emission indicates that the volatilization of mercury mainly occurred as a result of the vaporization of elemental mercury in soil. The degree of Hg emission differed significantly among the soil sites studied, which may be due to variations in soil texture, organic matter content and soil compaction.

    Temephos is an insecticide widely used in Venezuela to control the proliferation of the larvae of Aedes aegypti (L.), the principal vector of dengue virus. The aim of this study was to identify the susceptibility to temephos of Ae. aegypti in four locations in western Venezuela: Lara, Tres Esquinas, Ureña and Pampanito. Larval bioassays were conducted on samples collected in 2008 and 2010, and the levels of α- and β-esterases, mixed-function oxidases, glutathione-S-transferase and insensitive acethyl cholinesterase were determined. Larval populations from western Venezuela obtained during 2008 and 2010 were found to be susceptible to temephos, with low resistance ratios and without overexpression of enzymes. The low RR values reveal the effectiveness of temephos in controlling the larval populations of Ae. aegypti. Control strategies must be vigorously monitored to maintain the susceptibility to temephos of these populations of Ae. aegypti. © 2013 Society of Chemical Industry.

    The highest densities of lakes on Earth are in north temperate ecosystems, where increasing urbanization and associated chloride runoff can salinize freshwaters and threaten lake water quality and the many ecosystem services lakes provide. However, the extent to which lake salinity may be changing at broad spatial scales remains unknown, leading us to first identify spatial patterns and then investigate the drivers of these patterns. Significant decadal trends in lake salinization were identified using a dataset of long-term chloride concentrations from 371 North American lakes. Landscape and climate metrics calculated for each site demonstrated that impervious land cover was a strong predictor of chloride trends in Northeast and Midwest North American lakes. As little as 1% impervious land cover surrounding a lake increased the likelihood of long-term salinization. Considering that 27% of large lakes in the United States have >1% impervious land cover around their perimeters, the potential for steady and long-term salinization of these aquatic systems is high. This study predicts that many lakes will exceed the aquatic life threshold criterion for chronic chloride exposure (230 mg L(-1)), stipulated by the US Environmental Protection Agency (EPA), in the next 50 y if current trends continue.

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

    Full Text Available AS ZONAS fronteiriças são zonas de empréstimos e apropriações culturais e, por isso, um lugar privilegiado para a compreensão do fenômeno migratório internacional. O objetivo deste trabalho é apresentar alguns aspectos do processo de deslocamentos transfronteiriços no norte do Brasil, no município de Pacaraima (Estado de Roraima e na fronteira sul da Venezuela, no município de Gran Sabana (Estado Bolívar, e, ao mesmo tempo, apontar as tendências e reflexos nas configurações socioculturais nessas zonas de contato. Nessa fronteira Brasil-Venezuela, podemos afirmar que o trânsito maior é de brasileiros para a Venezuela e para a Guiana, em decorrência das possibilidades de atuarem nas atividades de mineração, no comércio local e no setor de transportes, além das atividades ilegais, como tráfico de mulheres, contrabando de combustível e câmbio ilegal de moeda. Apresenta-se, no entanto, uma nova tendência que é a imigração de estrangeiros de outros países do continente, tais como peruanos e colombianos. Esses migrantes transfronteiriços percorrem os países fronteiriços em itinerários cuja porta de entrada é a Venezuela e a Guiana, mas também o Estado do Amazonas.BORDER zones are zones of cultural lending, borrowing and appropriation, and, therefore, a privileged vantage point for understanding the phenomenon of international migration. This essay attempts to examine certain aspects of the transborder dislocation process in northern Brazil (the city of Pacaraima, state of Roraima and in southern Venezuela (the city of Gran Sabana, state of Bolívar, and point out its trends and reflections on the sociocultural makeup of those contact zones. In this Brazil-Venezuela border, the largest movement is clearly that of Brazilians going into Venezuela and Guyana in search of job opportunities in mining, local business and transportation, not to mention illegal activities such as the traffic of women, fuel smuggling and

    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.

    Rabies is a zoonotic viral disease and in Zulia State, it constitutes a public health problem of a high social impact, due to the report of cases in human beings. In this study, the presence of urban rabies was determined in Zulia's State and its distribution was identified according to municipalities and affected species during 1996-2006. In the scope of a descriptive study, a documented revision of Zulia's State Zoonosis Regional Coordination registries for the period in study was carried out. A total occurrence of 1.033 rabies cases was observed, 1.017 were in animals and 16 in human beings. The biggest incidences were for Maracaibo (31.40%) and San Francisco (15.68%) municipalities. The type of predominant rabies was the urban one; the principal reservoir and transmitter was the canine one (91.60%). Of the reported cases in human beings, the biggest incidence was in in Maracaibo Municipality (37.5%) and the most affected age group was <15 years (81.2%). A low percentage in the coverage of vaccination was presented (33%). A high incidence of rabies is demonstrated in Zulia's State in spite of this being a preventable immune disease. A positive correlation was determined between the number of admissions and cases (rs=0.948 P<0.01). It is necessary to implement an effective control of the sources of infection and to support a minimal coverage of vaccination of 80% in canines and furthermore, to implement community education programs, to diminish the risk of infection and the occurrence of cases.

  13. STSHV a teleinformatic system for historic seismology in Venezuela

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

    2013-05-01

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

    2006-08-01

    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

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

  16. 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.

    Full Text Available El presente artículo tiene como objetivo describir el comportamiento del crecimiento económico en Venezuela para el período 2000-2010 a través de las variaciones del Producto Interno Bruto (PIB como indicador macroeconómico. El abordaje se enmarcó con una metodología de tipo descriptiva mediante la revisión de fuentes documentales. Por su parte, los hechos estilizados permiten evidenciar el comportamiento de la economía venezolana en el período de estudio y los elementos fundamentales de incidencia sobre el crecimiento económico. Finalmente se concluyó que los variantes e inestables niveles del crecimiento económico en los últimos años, estuvieron influidos generalmente por el gasto público auspiciado por los altos ingresos petroleros. La economía venezolana se caracteriza por tener un sector productivo “estrangulado”, no obstante, los últimos cinco años del período estudiado, el PIB ha presentado una propensión decreciente generado por la disminución del crecimiento económico. En suma, no se ha logrado subsanar y erradicar los problemas sociales más importantes en la economía venezolana como la pobreza, la inflación, el desempleo, entre otros; muchas de estas dificultades inciden directa y proporcionalmente sobre el bienestar social y por ende sobre el desarrollo humano, concluyendo que los beneficios económicos de los períodos de bonanza, no se trasladan en significativas mejoras de la calidad de vida.

    Full Text Available As in many other Spanish Empire’s provinces abroad, Venezuelan colonial society was based on hierarchical values and inegality. This was a direct consequence of translating Spain’s mores and forms to its American territories during trhe Conquest period. A creole nobility thus appeared that could not but behave accordingly to the values and principles of the Ancien Regime. Many creole noblemen, however, embraced the independentist movement and supported the political changes that put an end to the colonial order and gave way to a republican one. How this process same about, what contradictions emerged as it evolved and what ultimate effects —if any— it had upon the Provincia de Caracas is the main subject of this paper

    En Venezuela, como en otras provincias ultramarinas, se constituyó una sociedad jerárquica y desigual, consecuencia directa de la traslación y adecuación a estos territorios de las formas y procederes sociales existentes en España en el momento de la conquista. Como consecuencia de este proceso, se formó una nobleza criolla que actuó de acuerdo con los valores y principios jerárquicos de la sociedad del Antiguo Régimen. Muchos de los hombre pertenecientes a los sectores privilegiados de la sociedad se sumaron a la causa de la Independencia y apoyaron el cambio político que puso fin a la sociedad antigua y dio paso a la instauración de un orden republicano. Cómo se dio este proceso en la provincia de Caracas, cuáles fueron sus contradicciones y qué efectos tuvo sobre la sociedad resultante, es el objetivo del presente artículo.

    2013-05-01

    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.

    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.

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

    The Neotropical fauna of saucer bugs (Naucoridae) currently includes four monotypic genera. Recent extensive collecting in Venezuela has produced three new species in two of these genera. In addition, undetermined Guyanan specimens of one of the new species were found in the United States National Museum of Natural History. Thus, described here are Placomerus obscuratus n. sp. from Guyana and Venezuela with brachypterous and macropterous hindwing forms, and two species of Procryphocricos from Venezuela. Procryphocricos quiu n. sp. is described from the brachypterous forewing form and Procryphocricos macoita n. sp. from both brachypterous and macropterous forms. Previously described species also are discussed.

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

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