Resumen en español Dentro del marco del proyecto de microzonificación sísmica de las ciudades de Caracas y Barquisimeto se han realizado en la ciudad de Caracas diversos estudios geofísicos, geológicos y geotécnicos. A objeto de estimar la respuesta sísmica del valle de Caracas, se definieron 4 sismos escenarios que podrían afectar la ciudad, ubicados al norte, sur, este y oeste de la misma. Se realizaron simulaciones numéricas a lo largo de 3 perfiles 2D distribuidos en dirección (mas) norte-sur y este-oeste tomando como datos de entrada la información más actual que se dispone de las características geológicas y geofísicas del valle de Caracas. Los resultados de las simulaciones permiten identificar los rangos de frecuencias para los cuales se observan las mayores amplificaciones de las ondas sísmicas, los cuales serán comparados con los valores de frecuencias naturales obtenidos mediante el método H/V. Las simulaciones se realizaron utilizando un código numérico 2D basado en el método de elementos espectrales. Los resultados obtenidos evidencian la presencia de efectos 2D en el valle de Caracas, y muy probablemente efectos 3D como resultado de la geometría de la cuenca sedimentaria, como por ejemplo, en las zonas de Los Palos Grandes y San Bernardino. Las simulaciones a lo largo de esta última evidencian posibles efectos de interferencia entre dos subcuencas asociadas. Actualmente se adelantan estudios con una red sismológica temporal instalada en diversas zonas de la ciudad que permitirán a futuro comparar los resultados experimentales con los resultados obtenidos en las simulaciones 2D y 3D. Resumen en inglés During the seismic microzoning project of Caracas and Barquisimeto cities several geological, geophysical and geotechnical studies were carried out in Caracas. In order to estimate the seismic response of the Caracas Valley, four seismic scenarios were defined for this study, located at the north, south, east and west of the city. For each scenario, 2D numerical simulations were carried out across 3 profiles, two in north-south direction and the other in west-east directi (mas) on. The input for simulations is based on recent information obtained from geological and geophysical studies in the valley. The results obtained from numerical simulations allow us to identify the ranges of frequencies where the amplification factor of seismic waves propagation had maximum values, which will be compared with natural frequencies obtained from the H/V method. Numerical simulations were applied using a 2D numerical code based on the spectral element method. The results obtained show the presence of 2D effects in the valley response and probably 3D effects induced by the geometry of the sedimentary basin, such as the Palos Grandes and San Bernardino areas. The simulations across San Bernardino show possible effects of interference between two associated sub-basins. Currently, new studies are in progress with a temporal seismological network deployed in several zones of the city that will allow a future comparison of the experimental results with the results obtained from 2D and 3D simulations.

2006-12-01

Resumen en español El espesor de los sedimentos del área metropolitana de la ciudad de Mérida se cuantificó con base en el procesamiento e interpretación de datos geofísicos. A partir de datos gravimétricos se elaboró el mapa de anomalías de Bouguer para ρB=2,67g/cc y un nivel de referencia de 1500 metros sobre el nivel del mar, con un rango de variación de las anomalías entre -381,58 y -360,57 mGal. Se generó un modelo de densidad del subsuelo 3D coherente con la geología (mas) del área y datos geofísicos existentes, lo que permitió estimar un espesor máximo de 120 metros en la terraza de Mérida. Se realizaron modelos 1D y 2D de cinco perfiles sísmicos en la ciudad de Ejido, calculándose velocidades aparentes de ondas P y ondas S de 750-1115 m/s y 320-620 m/s, respectivamente para una primera capa con espesor máximo de 15 m. Para una segunda capa las velocidades varían entre 2080-2600 m/s para las ondas P y 550-830 m/s para las ondas S. El resultado final del estudio presenta la información compilada y generada mediante un Sistema de Información Geográfico. Resumen en inglés The thickness of soft sediments in metropolitan Merida city area was obtained from 3D gravimetric, 1D and 2D seismic refraction modelling. A Bouguer anomaly map was obtained with a Bouguer density of ρB=2.67 g/cc and a datum reference level of 1500 meters above sea level. Anomalies vary between -381.58 and -360.57 mGal. A tridimensional density model was generated based on geological and geophysical data. 1D and 2D models from five near surface seismic refraction pro (mas) files obtained in Ejido city showed the following results: apparent P and S waves velocities of 750-1115 m/s and 320-620 m/s to a first layer with a maximum thickness of 15 m. In a second layer the velocities are between 2080-2600 m/s to P waves and 550-830 m/s to S waves. The results were integrated in a geographic information system (GIS).

Lanza Tarricone, Giuseppe; Mago, Elys; Sogbe, Emir; Martínez, María
2004-04-01

Resumen en español Antecedentes: la fibrilación auricular se caracteriza en el electrocardiograma por la ausencia de onda P, presencia de onda f y variación en los intervalos R-R. Este tipo de ritmo afecta la remodelación auricular, el pronóstico en el infarto del miocardio. Un mapeo de la superficie auricular demuestra presencia de frentes de ondas que se perpetúan y afecta la amplitud del voltaje de los complejos ventriculares respecto a los intervalos R-R. Objetivos: registrar y com (mas) parar las diferencias de voltaje de complejos ventriculares tanto en la fibrilación auricular como en el ritmo sinusal. Métodos: se evaluaron 21 electrocardiogramas con fibrilación auricular y 23 con ritmo sinusal, registrándose el voltaje de las ondas R, la profundidad de las ondas Q y la sumatoria de R con Q. Resultados: de los pacientes con ritmo sinusal el 56,5 % eran del género femenino y el promedio de edad era de 50,7 ± 21,2 años. De los pacientes con fibrilación auricular 81,0 % eran del género masculino y el promedio de edad era de 67,4 ± 13,4 años. Tanto para la onda R, como para la onda Q y sus sumatorias netas, en todas las derivaciones, a excepción de la derivación D2 de la onda R (P= 0,095), se encontraron diferencias estadísticamente significactivas (P= 0,02 o menor) entre los electrocardiogramas de ritmo sinusal y fibrilación auricular. Conclusiones: existe una diferencia de voltaje entre los complejos registrados en el electrocardiograma con ritmo sinusal y fibrilación auricular. Resumen en inglés Background: the atrial fibrillation is characterized in the electrocardiogram by absence of wave P, presence of wave f and variation in the intervals R-R. This rhythm type affects the remodeling atrial, the prognosis in the attack of the miocardio. A map of the surface atrial demonstrates presence of fronts of waves that are perpetuated which affects the height of the voltage of the ventricular complexes in relation to the intervals R-R. Objectives: to register and to com (mas) pare the differences of voltage of the complex R-R in the atrial fibrillation as in sinoatrial rhythm. Methods: 21 electrocardiograms were evaluated with atrial fibrillation and 23 with sinoatrial rhythm, registering the voltage of the waves R, the depth of the waves Q and the sum of R with Q. Results: Of the patients with sinoatrial rhythm 56.5 % was female and the age average was of 50.7 ± 21.2 years. Of the patients with atrial fibrillation 81,0 % was male and the age average was of 67.4 ±13.4 years. For wave R, as for wave Q and their additions in all the derivations, excepted derivation D2 of the wave R (P= 0.095), it was found statistically significant differences (P= 0.02 or less) among the electrocardiograms of sinoatrial rhythm and atrial fibrillation. Conclusions: a voltage difference exists among the registered complexes in the electrocardiogram between sinoatrial rhythm and atrial fibrillation.

Dinámica submareal y condiciones ambientales de la ría Deseado, Santa Cruz/ Subtidal dynamics and environmental conditions of the Río Deseado estuary, Santa Cruz

Isla, F.; Iantanos, N.; Estrada, E.
2004-09-01

Resumen en español La geometría del estuario del río Deseado, las condiciones climáticas semiáridas y la morfología de los cañones labrados en volcanitas han contribuido al dominio del régimen macromareal en este sector de la costa patagónica. A su vez, los efectos de las corrientes de marea se acentúan debido al empobrecimiento en el caudal del río, que en función del valle que se observa en la actualidad, debió haber llevado un importante caudal alimentado por las aguas de fus (mas) ión de la masa de hielo que rellenaba la cuenca del lago Buenos Aires. Cuando los hielos dejaron libre el valle del río Baker, el lago comenzó a desaguar hacia el Pacífico, dejando casi seco al río Deseado, que sólo recibe los aportes de los ríos Pinturas y Fénix Grande. La atenuación de la marea se reconoce en la gradación de los sedimentos de fondo: gravas en Puerto Deseado, arenas en la bahía Uruguay y fangos en la bahía Concordia. Las formas de fondo reconocidas como sonografías destacan megaóndulas bidimensionales orientadas según el flujo en el sector de isla de los Pájaros, y ondas de arena orientadas según el reflujo que se ubicaron a mayor profundidad hacia el interior de este sector de acumulación. Los registros de sonar lateral así como los muestreos de fondo confirmaron fondos planos arenosos con gravas en bahía Uruguay, y surcos erosivos (furrows) constituidos en fangos en el interior de la bahía Concordia. La mezcla de aguas marina y dulce se produce en Puesto El Paso mientras que en la bahía Concordia se dan los máximos de turbidez. Resumen en inglés The geometry of the Río Deseado estuary, the semiarid climatic conditions and the morphology of gorges carved into volcanic rocks contributed to the dominance of a macrotidal regime in this part of the Patagonian coast. In turn, the effects of tidal currents are increased due to the impoverishment of the Río Deseado discharge, whose valley used to drain the ice cover that occupied the Lago Buenos Aires basin. When the Río Backer valley became free of ice, the lake bega (mas) n to discharge to the Pacific Ocean. Since then, the Río Deseado has received only the supply of the Pinturas and Fénix Grande rivers. The decrease of the tidal action towards the headlands produces a grain-size segregation in the bottom sediments: gravel at Puerto Deseado, sand in Bahía Uruguay and mud in Bahía Concordia. Bedforms recognized in side-scan sonar records distinguished flood-oriented 2-D megaripples in the area of isla de los Pájaros, and ebb-oriented sand waves at a greater depth and some kilometres inland in the inlet of Bahía Uruguay. Sonographs and bottom samples confirmed flat beds composed of sands with gravel in Bahía Uruguay and furrows eroded in muds in Bahía Concordia. Water mixing (marine and freshwater) occurs in Puesto El Paso while turbidity maximum was measured in Bahía Concordia.

Resumen en español Introducción El tilt test (TT) es un método diagnóstico de rutina para evaluar la función autonómica de pacientes con síncope. Debido a su tasa elevada de resultados falsos negativos y al tiempo que insume, el desarrollo de nuevas metodologías que puedan facilitar el diagnóstico ha ganado una importancia creciente. Un equipo desarrollado en la Argentina permitió establecer una metodología confiable, reproducible y no invasiva para la medición de la velocidad de (mas) onda de pulso carotídeo y radial durante un TT convencional y determinar si tiene el potencial de predecir precozmente el resultado de esta prueba. Objetivo Evaluar la utilidad del retraso en la aparición de la onda de pulso desde el inicio del QRS para predecir el resultado del tilt test. Material y métodos Se realizó un estudio observacional en pacientes consecutivos derivados para el estudio de síncope a través de la realización de un TT. Durante la prueba se registraron simultáneamente la presión arterial y la frecuencia cardíaca y la onda de pulso radial y carotídeo mediante un polígrafo diseñado especialmente. Se evaluó la capacidad del retraso en la aparición de la onda de pulso desde el inicio del QRS para predecir el resultado del TT mediante análisis univariado y multivariado. La capacidad para predecir el resultado de la prueba se evaluó a través del análisis de curvas ROC. Resultados Se incluyeron 43 pacientes, 24 (55,8%) mujeres. El TT fue positivo en 18 pacientes (11 mujeres). En el análisis univariado, el cambio de la presión arterial sistólica (p = 0,02) y diastólica (p Resumen en inglés Background The tilt test (TT) is a diagnostic tool used to evaluate autonomic function in patients with syncope. However, as TT has a high rate of false positive results and the duration of the test is long, new strategies are emerging. A device developed in Argentina allowed establishing a non-invasive, reproducible and reliable method to measure pulse wave velocity in the carotid and radial arteries during a conventional TT and to determine its likelihood to predict the (mas) result of the test. Objective To assess the usefulness of time delay of the pulse waveform from the onset of the QRS complex in order to predict the result of the tilt test. Material and Methods We conducted an observational study on consecutive patients with syncope referred to the tilt test laboratory. During the test blood pressure, heart rate and carotid and radial pulse waves were recorded simultaneously with a specially designed polygraph. Univariate and multivariate analyses were performed to assess the ability of time delay of the pulse waveform from the onset of the QRS complex to predict the result of the TT. This ability was evaluated with the analysis of ROC curves. Results A total of 43 patients were included; 24 (55.8%) were women. The TT was positive in 18 patients (11 women). Univariate analysis determined that changes in systolic blood pressure (p=0.02) and diastolic blood pressure (p

Resumen en inglés Background: From January 2000 to June 2002, the first Chilean registry of unstable angina was carried out, with the participation of 15 hospitals. Aim: To report the clinical and demographic features of 600 patients with unstable angina, their risk profile and prognosis. Material and methods: The inclusion criteria for this prospective registry were a history of recent onset of chest pain ((mas) electrocardiographic changes and/or positive markers of myocardial damage. Results: Mean age of the patients was 65 years and 37% were women. Among coronary risk factors, 63% had hypertension, 27% had diabetes, 52% had dyslipidemia, 31% smoked and 21% had a family history of atherosclerosis. On admission 94% of patients had chest pain, associated to ST segment depression in 44%, negative T waves in 28% and positive markers of myocardial damage in 30%. Fifty seven percent received intravenous nitroglycerin, 47% received oral nitrates, 69% beta blockers and 15%, calcium antagonists. Antithrombotic therapy included aspirin in 96%, heparin in 74%, ticlodipine or clopidogrel in 19% and IIb/IIIa inhibitors in 12%. A coronary angiogram was performed in 52%, angioplasty in 25% and coronary bypass surgery in 13%. Hospital mortality was 2.6%. The incidence of new ischemic events was: myocardial infarction in 2.8% recurrent ischemia in 9.5% and refractory ischemia in 2%. The incidence of adverse events increased according to a higher risk profile. Conclusions: The demographic and clinical features, treatment and mortality of these patients are similar to those reported in international registries, with a low mortality rate (Rev Méd Chile 2004; 132: 135-43)

Resumen en español En las costas del sudeste de Buenos Aires hay dos relieves geomorfológicos de importancia, las playas arenosas bajas con grandes campos de médanos, y las playas de bolsillo ubicadas entre acantilados de loess u ortocuarcitas. Al Norte y Sur de la ciudad de Mar del Plata, hay extensos campos de médanos que conforman la Barrera Oriental y Austral. La conformación de estas costas es relativamente moderna ya que se han formado con posterioridad a la fluctuación holocena (mas) del nivel del mar. El objetivo del presente estudio se centró en analizar los cambios morfológicos naturales y artificiales de las playas de los partidos de Pinamar, Villa Gesell, Mar Chiquita, General Pueyrredón, General Alvarado, Lobería y Necochea, mediante la descripción y discusión de resultados obtenidos en relevamientos de playa realizados desde 1983 al 2004, con especial énfasis en la dinámica sedimentaria de sus playas y las características físicas naturales o introducidas por el hombre, como por ejemplo construcción de obras de defensa o movimiento de arenas. Los relevamientos se ejecutaron en playas con diferente orientación, dinámica, cantidad y calidad de sedimento, así como distinto grado de alteración producido por las actividades humanas. Los perfiles permitieron analizar la magnitud y velocidad de los cambios morfológicos, al tiempo que se estudiaron las variaciones texturales de las distintas zonas de la playa, reconociendo su variabilidad y la significación estadística de la misma. El trabajo se basó en la comparación de relevamientos planialtimétricos de las playas según métodos convencionales, en la evaluación de las características físicas de las olas que llegan a ellas para alcanzar una clasificación morfodinámica basada en las ecuaciones del número de Dean, parámetro W, el número de Battjes y el parámetro de Guza e Inman. Las texturas se analizaron de muestreos superficiales de sedimentos de la playa distal y de playa frontal mediante los parámetros de Folk y Ward. También fueron evaluadas las pendientes de las playas. En la discusión se evaluó la morfodinámica de playas, sus texturas, la respuesta de las playas mixtas de arena/grava, los ciclos estacionales, tormentas sudestadas y eventos El Niño, así como el efecto de las dorsales de arena (sand ridges) y la refracción. También se evalúa la actividad antrópica, con la construcción de espigones, el relleno artificial, las construcciones sobre la playa, los pluviales, la fijación de médanos y las actividades extractivas. Las conclusiones sostienen la idea de cuatro procesos que interactúan en las modificaciones morfodinámicas de las playas analizadas como son los ciclos estacionales invierno/verano, los ciclos episódicos ligados a períodos tormentosos y de inundaciones, los efectos antrópicos, y la presencia de bancos arenosos submareales que modifican el ángulo de incidencia de las olas produciendo efectos locales. Resumen en inglés Along the coast of the Southeastern Buenos Aires Province (Fig. 1), there are two important geomorphologic relieves: low sandy beaches with dune fields, and pocket beaches located between loessic or quarcitic cliffs. To the North and South of Mar del Plata City, extense dune fields conform the Eastern and Southern barriers. These dune fields are very modern, since they have been formed as consequence of a Holocene sea-level fluctuation (Schnack et al., 1982; Violante and (mas) Parker 1993; Isla, 1997). The objective of the study was to analyse the natural and artificial morphological changes of the beaches of Pinamar, Villa Gesell, Mar Chiquita, General Pueyrredón, General Alvarado, Lobería and Necochea counties, and the description and discussion of results obtained from 1983 to 2004. Special emphasis was made to the sedimentary dynamics of these beaches and the changes induced by man-made structures (groynes fields) and sand mining. The beaches have different orientation, dynamics, grain size, as well as different human alteration degree. The work was based on the comparison of beach profiles according to conventional methods (Fox and Davis, 1978; Isla, 1992; Isla et al., 1994; Bértola, 2001), the evaluation of the morphological classification based on Dean's number (Dean, 1973), Omega parameter (Masselink and Short, 1993), Battje´s number (Short, 1996), and the parameter of Guza and Inman (1975). Surface grain sizes were analysed using the parameters of Folk and Ward (1957) and evaluating beach slope changes. North Area Morphology: These are oceanic beaches, with average width of 72 m., The berm remains stabilised or it is in setback. Berm width increases at the touristic area in Mar de las Pampas. Villa Gesell beaches (Spa Los Históricos) suffered significant variations. In the pristine areas, there is presence of dunes after the backshore, although many of them are forested. Balance: In this area, there are no structures or estuaries that could affect the littoral drift. The Pinamar-Cariló sector has recorded an important accumulation (27,580 m³) diminishing toward the North of the urban area. The beach of Villa Gesell has also registered accumulation (18,200 m³), except in certain areas of the centre of the urban area, where erosion existed. Toward the South of Mar de las Pampas, the trend is depositional again. Grain sizes: The sediments of the backshore have increased their size up to 1994 and begin stable since 2000. In the foreshore, the mean (phi) has a reduction tendency. It diminished from 1994 to 1996 where it stops then increases very slowly. In some samples of Mar de las Pampas and Mar Azul, bioclastic composition dominates that would indicate a source of contribution from the South that coincides with old places of extraction of sands for construction. In addition, to the South of Villa Gesell, the erosion of dunes exhumes old beach crests or non-operative overwash composed by sand with shells and gravels (Isla, 1998). Slopes: Slope increases from South to North, with anomalous values in the centre of Pinamar. Temporarily, the general slopes increase their value in the time since 1998. Central Area Morphology: General Pueyrredón beaches change from North to South in: a) beaches among closed groynes, b) artificially refilled beaches, c) oceanic open beaches, and d) beaches at the foot of cliffs; in Miramar there are also beaches among groynes, but these with more spacing to each other (e). Beaches between groynes characterise La Perla area, with average widths of 64 m. Beach fills were conducted from Playa Popular to Playa Grande, their widths are of 107 m. The oceanic beaches extending from Mar del Plata Harbour to the Punta Mogotes Lighthouse and have 102 m. Beaches at the foot of cliffs (Costa Hermosa to Los Acantilados) are narrow, about 60 m. Those beaches between groynes from Chapadmalal to Miramar are 75 m. The beaches oriented to the Southeast have higher dynamics (Alfar, Chapadmalal and Miramar) with volumetric variations of the order of several thousands of cubic meters. Some have antrophic action that modifies totally and in a few days their morphology, for what we should absorb of the seasonal effects of erosion in winter and accumulation in the analysis of the results in spring. To the end of winter, beaches recover. Balance: The beaches of General Pueyrredón and Miramar are mixed and complex. There are pocket beaches, and beaches with abrasion plains; there is an important component of constructions of coastal defences. Mar del Plata beaches recorded an erosive trend (-2.266 m³) excluding the refilled volumes of 1998. This demonstrates the natural eroded tendency in the beaches without artificial feeding. Toward the North of the urban area of Mar del Plata there is accumulation, in their Central section there is erosion and toward the South of the urbanisation (Punta Mogotes Lighthouse) there is accumulation again. To the South -cliff areas-, erosion dominates. As expected, the highest variability was recorded at the refilled beaches, but there are significant dynamics at other of them (Acevedo, Spa Camping El Faro and Los Acantilados). General Alvarado beaches registered an important accumulation of 28.000 m³ of sand, of which 20% belongs to the urban coastline of Miramar (Spa HR). Grain sizes: In these beaches, the sediments have gone increasing the mean from 1998. The beaches increased the size of their sands toward the North, with fine grains in the refilled beaches and for the effect of tombolo in Los Pinos Beach (Alfar). In some samples of Chapadmalal, coarse grains of basaltic and andesitic composition have been detected in the bottom of the backshore, and pebbles of loess in the top of the backshore. This would indicate a particular dynamics that accumulates rolling stones transported by coastal drift from the South, the first one presumably of patagonic pebbles and of eroded material of the cliff bordering, in the second. Slopes: Beach slopes decrease from North to South, with abrupt peaks in the centre of the urban areas of Mar del Plata. The extreme values in the slopes were observed in the resort places from the downtown. Temporarily, the variations in the slopes were very important; in general a tendency was appreciated to increase the slope of the general beach along the time (except in beaches like Alfonsina, Las Dunas and Los Acantilados). South Area Morphology: The beaches of this area are open and with Loess cliffs. From Miramar to Mar del Sur beach widths extend to 79 m, and from Mar del Sur to Necochea they are narrower (68 m). Touristic activities diminish southwards. The beaches with more dynamics are those that possess groynes, cliffs and abrasion plains, as long as the beach open of Cruz del Moro has had smaller volumetric variations. Some beaches have suffered antrophic action (Costa Bonita or Cruz del Moro) that modified their morphology. Balance: They are heterogeneous beaches, with cliffs and engineering works in Mar del Sur and Costa Bonita, and open beaches in Cruz del Moro and Arenas Verdes. It begins to be important the action of the streams that in certain cases obstruct the longshore drift or they are plugged by effect of the same one. In General Alvarado accumulation is appreciated toward the North and South of the urban area of Miramar, with an important accumulation in Mar del Sur. Lobería presents erosion in its entire coast (-14.746 m³) with more loss in its Eastern sector. Costa Bonita beaches have more dynamics and Cruz del Moro suffer less variability. In both municipalities, erosion cycles and accumulation were observed along the year in correspondence to seasonal variations. Grain sizes: In the beaches of this area, an increase of the value of the mean is appreciated from 1995. In the backshore, grain size diminishes toward the South and in the foreshore, increase toward the South. Slopes: Slopes increase from North to South. With relationship to the foreshore, the slopes are had increasing through the time and all the beaches have had important variations equally. In the discussion, morphodynamics and grain sizes were evaluated, considering specially the dynamics of beaches composed of sand and gravel. The human impact was evaluated in relation to groin construction, nourishment works, buildings at the beach, dune afforestation and sand mining. The conclusions sustain the idea of four interaction processes: 1) seasonal cycles, 2) storms and flood effects, 3) human impact, 4) presence of sand ridges that modify the angle of incidence of the waves producing local effects. The refilled beaches have passed of being reflective to dissipative; as it has only modified slopes and grain size (but not climate of waves), there is still erosive. Erosive beaches have higher slopes (more than 4%). The increase of the slope toward the North indicates more narrow beaches with smaller areas of dry sand. Southeastern beaches are therefore more vulnerable to storm effects. The differential refraction of the waves in the Southeast, generates the continuous energy concentration in certain places of the coast (for example the cliffs in Mar del Plata). Induced for sand ridges there is convergence -erosion- and divergence -sedimentation- of orthogonal separated by few kilometres of distance. The protection of the coast cannot be considered as an individual responsibility, and for it, although local solutions exist, they don't work to regional scale; therefore, the coastal defence should be a cooperative effort among all the coastal municipalities.

INTRODUCCIÓN AL PROBLEMA DE LA EROSIÓNLITO RALEN URABÁ (SECTOR ARBOLETES - TURBO) COSTA CARIBE COLOMBIANA/ Introduction to littoral erosion problem in Urabá (Arboletes-Turbo area) Colombian

Correa, Iván D.; Vernette, Georges
2004-12-01

Resumen en español La erosión litoral ha sido la tendencia histórica dominante a lo largo de los aproximadamente 145 km de línea de costa entre las ciudades de Arboletes y Turbo (sur del Litoral Caribe colombiano). En las cuatro últimas décadas ocurrieron retrocesos de la línea de costa del orden de los 50-100m en varios sectores (Uveros, Damaquiel, Zapata, Turbo), y de hasta 1.6 km en el área Punta Rey-Arboletes, en la cual las pérdidas de terrenos suman más de 4.5 km2 y la erosi� (mas) �n alcanzó tasas máximas de hasta 40m/año. La síntesis de la información disponible sugiere que la “susceptibilidad” generalizada a la erosión podría ser la respuesta a ascensos relativos del nivel del mar, asociados a la tectónica regional, a los efectos del diapirismo de lodos y a la hidroisostacia, entre otros posibles factores. En los sectores más críticos (Arboletes y Turbo), las tendencias erosivas naturales fueron aceleradas por intervenciones humanas como la desviación del río Turbo, la extracción intensiva de materiales de playa y el manejo inadecuado (o no manejo) de las aguas lluvias y residuales. El costo actualizado de las 155 obras de defensa (espolones, barreras y muros de contención que totalizan 6.2 km de longitud y un volumen de materiales de 37.000m3) construidas hasta agosto del 2000 se calcula en alrededor de los $ Col 10.000 millones. Con muy pocas excepciones, los espolones perpendiculares a las playas no han recuperado arenas y más bien se han convertido en generadores de nuevos problemas en los sectores adyacentes. A corto plazo, la erosión litoral entre Arboletes y Turbo es causada tanto por factores marinos como por procesos de erosión subaérea y es función en buena parte de las litologías poco resistentes de las terrazas y acantilados, compuestos en su mayoría por lodolitas fracturadas y eteorizadas (con buzamientos o planos de debilidad inclinados hacia el mar) y por sedimentos finos no consolidados, fácilmente licuables: ambas condiciones facilitan la ocurrencia de deslizamientos, caídas de rocas y flujos de lodo que determinan retrocesos rápidos (3 a 4 metros) del contorno litoral, sobre todo en los primeros 15 días de la transición verano-invierno (abril) y durante los “mares de leva” (periodos de oleajes fuertes). El caso de la erosión litoral entre Turbo y Arboletes ilustra claramente cómo las tendencias erosivas naturales pueden intensificarse fuertemente por intervenciones humanas (incluyendo las defensas ingenieriles) y la necesidad urgente de coordinar esfuerzos para controlar o mitigar con eficiencia las pérdidas de terrenos litorales. Resumen en inglés Caribbean coast. Shoreline retreat has been the net dominant historical trend along the 145 km-length littoral between Arboletes and Turbo (Southern Caribbean of Colombia). For the last four decades, there were identified in this littoral shoreline retreats of about 50-100m in several places (Uveros, Damaquiel, Zapata, Turbo) and a maximun of 1.6 km in the Punta Rey-Arboletes area, where land losses were of 4.5 k m2, at exceptional rates of 40m/year. The synthesis of the (mas) available information suggest that the general “susceptibility” to erosion between Arboletes and Turbo could be related primarily to relative sea level rise, associated to tectonic movements as well as to the effects of mud diapirism and hydroisostacy. In the more critical areas (Arboletes, Turbo), the natural erosive trends were accelerated by anthropic actions, including river diversion (Turbo), beach mining, and inadequate (or total absense) practices for controlling residual and natural waters. Up to August 2000, there were invested about $ Col 10.000 billions in 155 engineering defences (groins, sea walls and rip-rap which totalize 6.2 km of total length and a volume of materials of 37.000 m3). With few exceptions, groins have not been successful and are now part of the problem, accelerating shore erosion along the adyacent sectors. In the short term, the littoral erosion between Arboletes and Turbo is caused both by marine and by subaerial factors. It is facilitated by the poor lithological strengths of cliffs and marine terraces, mainly composed of highly fractured and weathered claystones and mudstones (with stratification and weakeness planes dipping toward sea) and nonconsolidated, easily liquefacted, fine sediments; both conditions facilitate the occurrence of rocks falls, slides and mud flows that result in high figures of cliff retreat (3 to 4m), specially during the first 15 days of the summer-winter transition (april) and in high waves periods. The case of the littoral erosion between Arboletes and Turbo illustrates well how the natural erosive trends of an area can be accelerated by human interventions and the urgent need for coordinating efforts to cope with littoral land losses.

Resumen en inglés Background: One of the most important factors involved in the pathophysiology of gastroesophageal reflux disease (GERD) is the lower esophageal sphincter rest pressure (LESRP), but these patients can have esophageal motor disorders (EMD). Aim: To assess an association between LESRP and the appearance of EMD in patients with GERD. Subjects and methods: A cross-sectional study was conducted in 229 patients with GERD and 49 healthy controls. Forty five patients with LESRP &l (mas) t; 6 mmHg and a mean age of 49 years were assigned to group 1, 128 patients with a LESRP between 6 and 12 mmHg and mean age of 47 years were assigned to group 2, 56 patients with a a LESRP >12 mmHg and a mean age of 47 years were assigned to group 3 and group 4 was conformed by 49 healthy subjects aged 40 years old. Esophageal manometry was performed using previously published techniques. Results: There was a significant association between LESRP, waves amplitude and the frequency of tertiary waves. Conclusions: Resting lower esophageal sphincter pressure is inversely proportional to the presence of esophageal motor disorders in patients with gastroesophageal reflux disease.

Ewes were randomly divided in two treatments (n=7/treatment): T1 with natural cycle and T2 synchronized with two injections of PG. From one day before PG injection until next ovulation, daily transrectal ultrasonography was done. All follicles ³2 mm were assessed. During the interovulatory intervals, follicular growth and regression occurred in a wav (mas) e like pattern (2-3 waves). The maximum diameter of the largest follicle of the first wave was greater in T1 (5.83 ± 0.31 mm) compared with T2 (5.0 ± 0.1 mm; P

Bostezo y epilepsia del lóbulo temporal/ Yawning and temporal lobe epilepsy

Muchnik, S.; Finkielman, S.; Semeniuk, G.; De Aguirre, M. I.
2003-04-01

Resumen en español La epilepsia del lóbulo temporal, es aquella epilepsia parcial donde las estructuras temporales límbicas son las responsables de los principales síntomas ictales. Se caracteriza por la recurrencia de crisis parciales simples y complejas con confusión post-ictal y amnesia del evento. El efecto facilitador del sueño No REM en la propagación de las crisis, como las anormalidades del sueño provocadas por la epilepsia del lóbulo temporal, son evidenciadas claramente en (mas) nuestros pacientes. El bostezo es un reflejo fisiológico, principalmente inducido por el despertar y el adormecimiento, puede estar asociado a diferentes enfermedades neurológicas. Su relación con la epilepsia de origen límbico, ha sido escasamente mencionada. Describimos en un paciente, un episodio de bostezos y crisis parcial compleja mientras dormitaba. El EEG mostró actividad irritativa focal, independiente y bilateral en regiones temporales medias. Tratado con carbamazepina 400mg/d, no repitió el episodio. Otro paciente presentó crisis parciales complejas secundariamente generalizadas con episodios de bostezos en el período post-ictal, luego de las siestas. El EEG fue normal y la polisomnografía nocturna mostró actividad irritativa sincrónica y bilateral en regiones temporales medias con generalización secundaria. Tratado con divalproato de sodio 750 mg/d, no se registraron nuevos episodios. La epilepsia del lóbulo temporal, el ciclo sueño-vigilia y el bostezo, parecen compartir no solamente las mismas estructuras anatómicas, sino también los mismos mecanismos neuroquímicos. El hecho de que los opiáceos endógenos sean considerados como parte de un sistema protector que inhibe y previene las crisis, permite postular que el bostezo sería la expresión de los mecanismos inducidos por los opiáceos endógenos que inhiben y previenen las crisis de la epilepsia del lóbulo temporal. Otro punto de vista sería presentar al bostezo simplemente como una forma particular de epilepsia temporal. Resumen en inglés Temporal lobe epilepsy is a partial epileptic disorder in which mesial structures are responsible for the principal ictal symptoms. Its characteristic feature is the recurrence of simple and complex partial seizures, associated with postictal confusion and amnesia of the event. The facilitating effect of NREM sleep on the propagation of the seizure, as well as the sleep abnormalities provoked by epilepsy were evident in our two patients. Yawning is a physiological reflex (mas) induced by arousal and drowsiness and may appear in different neurological conditions. Its relation with epilepsy of limbic origen has been rarely reported. We describe in a 95 year old male patient, the occurrence of yawning followed by complex partial seizure during a state of drowsiness. His EEG showed independent bilateral interictal foci of temporal sharp waves and after being medicated with carbamazepine 400mg/day, the episode did not recur. Another patient, a 17 year old female, displayed complex partial seizures and secondarily generalized seizures with yawning during the posictal period, after naps. The EEG was normal and her polysomnography showed bilateral synchronous temporal spikes and slow waves with secondarily generalization during stage 2 of NREM sleep that produce paroxysmal microarousals and increased stages 1 and 2 of NREM sleep and REM sleep diminished. After being medicated with divalproex sodium 750 mg/day, she suffered no futher seizures. Temporal lobe epilepsy, sleep- wake cycles and yawning seem not only to share the same anatomic structures but also the same neurochemical mechanisms. The fact that endogenous opiods are considered as part of a protective system that stop and prevent seizures may allow us to postulate that yawning would be the expression of the endogenous opiods induced mechanisms that stop and prevent the recurrence of the temporal lobe epilepsy. Another hypothesis may be that this is only a particular form of temporal lobe epilepsy.
