Estudio hidrogeológico de la cuenca del Francolí. Cronología de las aguas subterráneas

Tlie lower part of the Francolí river basin -Baix Camp of Tarragona- is constituted by Miocenic materials, from which have been identified the sedimentary means where they were originated and ground water formations that there are on it. The head zone of the studied basin, up to the Con- gost de la Riva, proved to be impermeable in general. It has been carried out its hydrologic study by means of radioactive isotopes in the different permeable means of the Baix Camp, limiting the methodology to the control of the tritium content of rain water precipitated in this zone, and impounded water in the different ground water formations. That has permited on the one hand, with the piezometers control, to establish the dynamic of the different ground wa- ter formations as well as to judge about the relations recharge-present extraction. On the other hand, the problem of the infiltration rnechanism has been undertaken in qualitative form

Relación entre la extensión de conos de deyección y la de su cuenca. Cabo de Gata

En la vertiente occidental de las sierras del Cabo de Gata y tocando al mar, se extienden varios conos de deyección cuyas extensiones en superficie se ha comprobado son función de las de sus cuencas de drenaje, relacionándose ambas mediante una ecuación exponencial ya preconizada por DENNY (1967) y HOOKE (1968), para formaciones parecidas en zonas áridas, aunque de mucha mayor extensión; cmprobándose así el amplio intérvalo de validez de dicha relación, se preconiza su interés para acotar las extensiones que deberían ocupar conos de deyección actualmente erosionados, si se conoce la cuenca que actuó de área fuente.Se discute además para el caso que nos ocupa, el proceso dinámico y las condiciones morfológicas las que se formaron dichos conos de deyección, sobre los cuales la dinámica actual en aquella área no parece actuar de forma eficaz

Sobre el origen de las aguas termales de Caldes de Montbui

The thermal waters of Caldes de Montbui are studied in the present work. This study has been made begining with chemical analisys, 0-18 content and control during twelve months of tritium contents; all this directed to be able to opine about the origin of these waters. It is concluded that the waters have a meteoric origin, and it is established at the same time the theory for which its thermal origin may be owed to a geothermal sistem, for which it is offered a model of recharge

Ambientes sedimentarios en el Mioceno del Baix Camp de Tarragona

In this paper we undertake a synthesis of the sedimentary environments which we have found in the Miocene of the "Baix Camp de Tarragona". At the same time we venture at the possibility of the existence of some pre-miocene arid post-eocene conglomerates which would, nowadays, be disniantled by the erosion

Modelling bus contention during system early design stages

Reliably upperbounding contention in multicore shared resources is of prominent importance in the early design phases of critical real-time systems to properly allocate time budgets to applications. However, during early stages applications are not yet consolidated and IP constraints may prevent sharing them across providers, challenging the estimation of contention bounds. In this paper, we propose a model to estimate the increase in applications' execution time due to on-chip bus sharing when they simultaneously execute in a multicore. The model works with information derived from the execution of each application in isolation, hence, without the need to actually run applications simultaneously. The model improves inaccuracy with respect to the existing model, and tends to over-estimate. The latter, is very important to prevent that, during late design stages, applications miss their deadline when consolidated into the same multicore, causing costly system redesign.This work has been supported by the Spanish Ministry of Science and Innovation grant TIN2015-65316-P.

Displasia epifisaria hemimélica: Revisión de la literatura a propósito de un caso

La displasia epifisiaria hemimélica es una alteración infrecuente del crecimiento osteocartilaginoso a nivel de la mitad de una o varias epífisis, localizada generalmente en una extremidad inferior, existiendo diferentes formas clínicas. La edad de presentación suele ser precoz, apareciendo una tumoración indolora, idéntica a un osteocondroma, que debe ser extirpada para evitar complicaciones tales como dismetrías, angulaciones y artrosis secundaria. La recidiva es frecuente, por lo que es importante planificar la intervención y realizar una adecuada técnica quirúrgica.Dysplasia epiphysealis hemimelica is an uncommon alteration of bone and cartilage growth, located at the middle of one or more epiphysis, which usually affects the lower extremity in a variable fashion. It begins at a very early age, as a painless mass, just like an osteochondroma, and must be removed to avoid complications as leg length discrepancy, angular deformity and secondary osteoarthritis. It often recurs, and so is important to plan the most appropriate surgery for each case

Intoxicación por paraquat : revisión

En este trabajo se revisan las características de la intoxicación por paraquat, y se presentan 15 casos clínicos altamente sugestivos de dicha intoxicación. El paraquat es un compuesto bipiridilo ampliamente usado en agricultura. Debido a que la intoxicación tiene efectos progresivos e irreversibles, es importante conocer la posibilidad de acceso al tóxico, pero ello muchas veces no es posible. Dado que el diagnóstico muchas veces es difícil para el clínico, la observación de un distress respiratorio severo, que empeora progresivamente en ausencia de signos radiológicos significativos, justifica un diagnóstico presuntivo de intoxicación por paraquat.In this work, we review the characteristics of paraquat poisoning and compare it with 15 clinical cases highly suggestive of this poisoning. Paraquat is a bipyridzlium compound, widely used as a contact herbicide in agriculture. Because the poisoning has progressive and irreversible effects, it's important to know a definitive history of acces to paraquat, but it 's difficult. Because the problem of diagnosis remains difficult for the practitioner; a clinical features of progressively worsening respiratory distress, in absence of radiógraphic demonstration of adequate cause of dyspnoea, justify a pressumptive diagnosis of paraquat poisoning
