El Triásico de la región de Monterde-Alhama de Aragón (Provincia de Zaragoza)

Se estudian los materiales en facies Buntsandstein y Muschelkalk de los afloramientos triásicos situados entre Monterde y el Norte de Alhama de Aragón. Para ello se han levantado siete columnas estratigráficas, habiéndose obtenido dos de ellas con un mayor detalle. Después de establecerse seis grandes tramos (unidades litoestratigráficas informales), claramente diferenciables, se estudian las variaciones verticales dentro de cada uno de ellos, así como las relaciones entre los mismos. En las reconstrucciones paleogeográficas y en la evolución sedimentaria> se resalta tanto la existencia de importantes umbrales durante la génesis de las tres unidades inferiores, como la transición gradual de depósitos marinos a continentales, y la presencia de interrupciones sedimentarias que, a veces, originan paleosuelos bien desarrollados. [RÉSUMÉ] On a studié les materiaux en faciés Buntsandstein et Muschelkalk des afleurments triassiques compris entre Monterde et le nord d'Alhama de Aragón. On a levé sept colonnes, dont deux en détaille. Aprés avoir établi six unités litostratigraphiques informelles trés differentes, on a étudié les variations verticales de chaque une ainsi que ses relations mutuelles. On fait sortir des importants seuils pendant la genése des trois unités inferieures par les reconstructions paléogéographiques et l'evolution sédimentaire, ainsi que la transition paulatine des dépots continentaux a marins et divers interruptions de la sedimentation, soulignés parfois par des paleochenaux. [AB5TRACT] The Buntsandstein and Muschelkalk facies have been surveyed in the outcrops between Monterde and the North of Alhama de Aragón. Seven stratigraphic sections have been studied, two in greater detail. After stablishing six informal lithostratigraphical units, very different each other, thcir vertical variations are studied as well as their mutual relations. The palaeogeogi-aphic reconstructions and the sediníentary evolution point out the existence of several shoals during tSe genesis of tSe three lower units as well as tSe transition from continental to marine deposits and several sedimentary breaks, sometimes niarked by paleosoils

Diseño y prototipado de una herramienta inteligente para proponer la solución de ejercicios en la web

El desarrollo de este proyecto está basado en los Sistemas Expertos como la base para la construcción de un tutor virtual que responda a las solicitudes de distintas fuentes que puedan requerir el razonamiento lógico de un experto humano para la solución de problemas en un ambiente educativo. Se define a los sistemas expertos como un sistema de cómputo capaz de emular la habilidad de tomar decisiones de un especialista humano de manera que reaccione como tal ante una situación que se encuentra dentro de un dominio particular. Estos se conforman por dos componentes básicos: la base de conocimientos y el mecanismo de inferencia, los cuales interactúan para emular el proceso de solución de problemas de un expert

Covid-19 y su impacto en el sector poblacional La Ladrillera-distrito de Pucalá 2021

En la presente investigación se propuso el objetivo de poder evaluar el impacto de la COVID-19 en el ámbito ambiental del sector poblacional la Ladrillera-Distrito de Pucalá 2021. La presente investigación es cuantitativa, de tipo transeccional con un diseño no experimental de índole descriptiva. El trabajo se ejecutó en el Distrito de Pucalá, la cual se delimitó al sector poblacional la Ladrillera, y se basó en determinar el impacto de la COVID-19 por residuos biocontaminados y el impacto en la vegetación presente de la zona. Al final de la investigación se obtuvieron resultados donde el impacto de la COVID- 19 en el ámbito ambiental del sector poblacional la Ladrillera-Distrito de Pucalá en el año 2021 ha sido alto, esto debido a la generación de residuos biocontaminados, la mala disposición de los mismos y el desconocimiento por parte de la población para realizar una separación correcta. Así mismo, la afectación que tuvo en la vegetación del sector, donde estos residuos se han ido acumulando en los sardineles. El impacto de la COVID-19 en la generación de residuos biocontaminados es alto, al igual que su impacto en la vegetación del sector poblacional la Ladrillera-Distrito de Pucalá en el año 2021 es de la misma magnitud

Geological factors of the Guadalajara landscapes (Central Spain) and their relevance to landscape studies

The landscapes of a territory are the consequence of its history; overlapped geological, vegetable and cultural histories usually exist on a landscape. At the Mediterranean domain, however, a translucent vegetation exists, and its history is closely related to the geologic and cultural histories, because low-technology agricultural uses on a different hardness rock background control vegetation. Thus, in areas like the Guadalajara province, the geologic composition and the human activities can be considered the primary conditions for landscape configuration. Both condition the typologies, distribution and relative importance of the geotic, biotic and anthropogenic components of landscapes. A complex network of interrelations among all them exists but, in the base of which lie the geology of the territory, included relief, because it has amore independent influence since man cannot modify the geologic factors; such as the colour of the rocks, the size and distribution of rock bodies, the palaeogeographic domains and the tectonic structure all which control landscape development and configuration. Moreover, geology influences conditions and even limit, the presence, typologies and development of the biotic and anthropogenic elements. These factors also have a major relevance for environmental management, educational and economic policy, and, in some cases, for environmental impact assessment

An Evaluation of the Effectiveness of Risk Minimization Measures for Tigecycline in the European Union

Background: Risk minimization measures (RMM) were implemented from February 2011 in the European Union to address risks of superinfection, off-label use and lack of efficacy associated with tigecycline. The objective of this study was to evaluate RMM effectiveness by describing prescription patterns among adults and children treated with any dose of tigecycline for any indication pre- and post-RMM implementation; incidence proportions of superinfection and lack of efficacy among adults treated with approved doses of tigecycline for complicated intra-abdominal infection and complicated skin and soft tissue infection were also evaluated. Methods: This was an observational, retrospective chart-abstraction study, including charts from 777 patients (399 pre-RMM, 378 post-RMM) at 13 sites across Austria, Germany, Italy, Greece and the United Kingdom (UK). Potential superinfection and lack of efficacy cases among those using tigecycline for on-label indication, age, dose, and duration were adjudicated. The distribution of indications for tigecycline was analyzed overall (i.e. across both study periods) and stratified by study period. Numbers and incidence proportions of superinfection and lack of efficacy cases (potential and adjudicated) were calculated overall and by study period. Results: Off-label use (indication or age) decreased from 54.2% [95% confidence interval (95% CI): 49.0, 59.3%] pre-RMM to 35.7% (95% CI 30.4, 41.2%) post-RMM. Overall, 45.7% (95% CI 41.9, 49.5%) of patients were prescribed tigecycline off-label; the most commonly reported off-label indications were characterized as \u201cother\u201d (25.5%), hospital acquired pneumonia (8.2%), other pneumonia (6.3%), bacteremia (5.2%) and diabetic foot infection (1.5%). Across study periods, incidence proportions of definite or probable superinfection and lack of efficacy in adults treated for approved indications, authorized treatment doses and duration were 4.5% (95% CI 2.1, 8.4%) and 5.5% (95% CI 2.8, 9.7%), respectively. Conclusions: Off-label use of tigecycline decreased following RMM implementation. Overall incidence proportions of definite or probable superinfection and lack of efficacy were low.

Risk Factors for Acute Kidney Injury Following Cardiac Surgery and Performance of Leicester Score in a Spanish Cohort

The incidence of acute kidney injury following cardiac surgery (CSA-AKI) is up to 30%, and it places patients at an increased risk of death. The Leicester score (LS) is a new score that predicts CSA-AKI of any stage with better discrimination compared to previous scores. The aim of this study was to identify risk factors for CSA-AKI and to assess the performance of LS. A unicentric retrospective study of patients that required cardiac surgery with cardio-pulmonary bypass (CPB) in 2015 was performed. The inclusion criteria were patients over 18 years old who were operated on for cardiac surgery (valve substitution (VS), Coronary Artery Bypass Graft (CABG), or a combination of both procedures and requiring CPB). CSA-AKI was defined with the Kidney Disease Improving Global Outcomes (KDIGO) criteria. In the multivariate analysis, hypertension (odds ratio 1.883), estimated glomerular filtration rate (EGFR) <60 mL/min (2.365), and peripheral vascular disease (4.66) were associated with the outcome. Both discrimination and calibration were better when the LS was used compared to the Cleveland Clinic Score and Euroscore II, with an area under the curve (AUC) of 0.721. In conclusion, preoperative hypertension in patients with CKD with or without peripheral vasculopathy can identify patients who are at risk of CSA-AKI. The LS was proven to be a valid score that could be used to identify patients who are at risk and who could benefit from intervention studies
