Abstract: Entre 1998 y 1999, el Consorcio de Bibliotecas Universitarias de Catalu a (CBUC) creó una nueva línea de trabajo: la Biblioteca Digital de Catalu a (BDC). ésta nació con la finalidad de contratar información electrónica interdisciplinar para la comunidad universitaria e investigadora de las bibliotecas miembro del Consorcio. Casi al mismo tiempo, esta línea de trabajo se amplió con la vertiente de la información propia generada por esta comunidad y se empezó a trabajar con la definición e implementación de repositorios electrónicos cooperativos. Estos últimos serán el objeto de este estudio. Se analiza su evolución, su estado actual, la estrategia para conseguir la inclusión de documentos (políticas institucionales, comités científicos, etc.), su contenedor (programas, tecnología usada, protocolos, etc.) y su contenido (estándares utilizados, derechos de autor, preservación, etc.). Por último se reflexiona sobre las ventajas, extraídas de la propia experiencia, de estos repositorios electrónicos cooperativos.Between 1998 and 1999, the Consortium of University Libraries of Catalonia (CBUC) created a new line of work: the Digital Library of Catalonia.

Abstract: although various measures have been implemented in spain with the aim to modyfing the behavior of motor vehicle users, it has not been observed a descending trend in traffic accident and injuries from traffic accident. this article considers the question of whether the measures taken to reduce motor vehicle crash-related injuries in spain have targeted the causes that are truly responsible for this trend. using several sources of data, beginning in 1990 it has been observed a significant reduction in traffic accidents and their consequences, but in the second half of the 90s the growth in motor vehicle crash-related injuries was similar to the increase observed in the 80s. likewise per capita alcohol consumption shows a downward trend from 1980 while the number of injuries has been strong associated with the economic cycle during the last twenty years. we conclude pointing out that intervention measures to control this problem in spain have focused mainly on modifying behaviour that increases the risk and severity of traffic accident injuries and have ignored the macro-economic determinants that explain the trend in the frequency of this health problem.

Abstract: En Espa a se han puesto en marcha diferentes medidas de intervención con el objeto de modificar la práctica de los conductores de vehículos de motor, sin embargo no se ha observado una tendencia descendente ni en la tasa de accidentes de tráfico ni en el número de víctimas relacionadas con los mismos. Este articulo se plantea el interrogante de si las medidas tomadas para reducir el número de víctimas por accidente de tráfico se han dirigido realmente hacia las causas responsables de esa tendencia. Utilizando diversas fuentes de datos se observa que en Espa a al comienzo de los a os noventa se produjo una importante reducción de la tasa de accidentes de tráfico y sus consecuencias, pero en la segunda mitad de la misma década el incremento en la tasa de lesiones por accidentes de tráfico fue similar al producido en los a os ochenta. Igualmente se observa que desde 1980 el consumo per capita de alcohol ha mostrado una tendencia descendente y que el número de lesiones por accidente de tráfico durante los últimos vente a os ha estado fuertemente asociado al ciclo económico. Se concluye se alando que las medidas para el control de este problema en Espa a se han centrado principalmente en la modificación de la conducta que incrementa el riesgo y severidad de las lesiones por accidente de tráfico, pero se han ignorado los determinantes macroeconómicos que explican la tendencia de la frecuencia de este problema de salud.

Abstract: Pheochromocytomas are thought to be uncommon in the elderly. However, the prevalence is likely to be higher than reported, as older patients are less likely to be diagnosed due to absence of classical symptoms of sympathetic overactivity and confounding effects of aging, comorbidities, and medications. We describe a hypertensive elderly patient with incidentally diagnosed pheochromocytoma complicated by recurrent urosepsis, cardiomyopathy, and fatal myocardial infarction. Our case demonstrates that, in older hypertensive patients without classical symptoms, orthostatic hypotension and urinary retention, which are common in the elderly, may indicate catecholamine excess and that the deleterious cardiovascular consequences of catecholamine excess in the elderly are not prevented by pharmacological α- and β-blockade.

Abstract: Many tropical terrestrial planarians (Platyhelminthes, Geoplanidae) have been introduced around the globe. One of these species is known to cause significant decline in earthworm populations, resulting in a reduction of ecological functions that earthworms provide. Flatworms, additionally, are a potential risk to other species that have the same dietary needs. Hence, the planarian invasion might cause significant economic losses in agriculture and damage to the ecosystem. In the Iberian Peninsula only Bipalium kewense Moseley, 1878 had been cited till 2007. From that year on, four more species have been cited, and several reports of the presence of these animals in particular gardens have been received. In the present study we have: (1) analyzed the animals sent by non-specialists and also the presence of terrestrial planarians in plant nurseries and garden centers; (2) identified their species through morphological and phylogenetic molecular analyses, including representatives of their areas of origin; (3) revised their dietary sources and (4) used Species Distribution Modeling (SDM) for one species to evaluate the risk of its introduction to natural areas. The results have shown the presence of at least ten species of alien terrestrial planarians, from all its phylogenetic range. International plant trade is the source of these animals, and many garden centers are acting as reservoirs. Also, landscape restoration to reintroduce autochthonous plants has facilitated their introduction close to natural forests and agricultural fields. In conclusion, there is a need to take measures on plant trade and to have special care in the treatment of restored habitats.

Abstract: With the aim of assessing an intervention program with teachers driven to promote the motivation skills in classroom, a field study was designed to measure the change, pre- and post-intervention, in the students in motivation, classroom environment and learning strategies. For this, 264 students of 1st year of Compulsory Secondary Education (CSE) and 253 of 3rd year, endorsed the CEAM (guest learning strategies and motivation), the CES (guest social climate in the class), and ACRA subscales of acquisition, coding, recovery and support. Results showed that the intervention program applied to teachers carried out to an improvement, among the students, in extrinsic goal orientation, self-belief and self-efficacy on performance. In relation to the classroom environment, the program enhanced it in the 3rd of the CSE. As for the strategies, coding was developed in both courses, while acquisition in 1st of CSE and attentional in 3rd. Finally, results support that the program was more effective intro females than males, and in 3rd year CSE students.
Fault Detection in a Heat Exchanger, Comparative Analysis between Dynamic Principal Component Analysis and Diagnostic Observers
Tudón Martínez, Juan C.;Morales Menéndez, Rubén;Ramírez Mendoza, Ricardo A.;Garza Casta?ón, Luis E.;Vargas Martínez, Adriana;
Computación y Sistemas , 2011,
Abstract: a comparison between the dynamic principal component analysis (dpca) method and a set of diagnostic observers (do) under the same experimental data from a shell and tube industrial heat exchanger is presented. the comparative analysis shows the detection properties of both methods when sensors and/or actuators fail online, including scenarios with multiple faults. similar metrics are defined for both methods: robustness, quick detection, isolability capacity, explanation facility, false alarm rates and multiple faults identifiability. experimental results show the principal advantages and disadvantages of both methods. do showed quicker detection for sensor and actuator faults with lower false alarm rate. also, do can isolate multiple faults. dpca required a minor training effort; however, it can not identify two or more sequential faults.

Abstract: Objetivo. Conocer la prevalencia del tabaquismo en la población derechohabiente usuaria del Instituto Mexicano del Seguro Social. Material y métodos. En un estudio transversal se entrevistó a la población usuaria de las 36 delegaciones, mediante un cuestionario estructurado y autoaplicable sobre el consumo de tabaco, edad de inicio, cantidad de cigarros y suspensión del consumo. Resultados. Se estudiaron 45 117 sujetos, en proporción similar por género. La prevalencia de fumadores fue del 40% en hombres, del 17.6% en mujeres y mayor en los estados del norte que en el resto del país. Existe un efecto de edad en el consumo de tabaco y más de la mitad de los fumadores iniciaron el hábito en la adolescencia. Conclusiones. La prevalencia de tabaquismo que se encontró es elevada, aunque el promedio de cigarros consumidos no es alto. No obstante, el índice de abandono es bajo. Se requieren medidas de intervención en salud pública para disminuir esta adicción.
