Reconstructing snow avalanches in the Southeastern Pyrenees

A regional study of snow avalanche processes was undertaken in the SE Pyrenees. Dendrogeomorphology was used to date and reconstruct large-scale snow avalanche events that occurred in the last four decades. Dendrochronological analyses yielded the dates of nine winters when avalanches occurred in the recent past in six studied avalanche paths. Some of these avalanches were already known, but others had not been documented. In one case, the existing avalanche path map was improved with the dendrogeomorphological information of a larger past event. As a result of the dendrogeomorphological analyses, evidence for three regional-scale major avalanche years was identified in the SE Pyrenees from 1971 to 2004: 1971¿1972, 1995¿1996 and 2002¿2003. The specific synoptic atmospheric situations and the most likely nivometeorological and snowpack conditions that released these major avalanches were determined using weather data for the seasons of major avalanche releases. In 1971¿1972 the snow avalanche episode was characterized by a deep trough crossing the Pyrenees. In 1995¿1996 a variety of meteorological situations produced several episodes of major avalanches. In 2002¿2003 the more significant of two episodes was attributed to a north advection pumping an arctic air mass over the Pyrenees. The 1995¿1996 avalanche season proved to be the most notable in the four past decades in the Pyrenees.

The Upper Oligocene of Montgat (Catalan Coastal Ranges, Spain): new age constraints to the western Mediterranean Basin opening

The Oligocene deposits of Montgat are integrated in a small outcrop made up of Cenozoic and Mesozoic rocks located in the Garraf-Montnegre horst, close to the major Barcelona fault. The Oligocene of Montgat consists of detrital sediments of continental origin mainly deposited in alluvial fan environments; these deposits are folded and affected by thrusts and strike-slip faults. They can be divided in two lithostratigraphic units separated by a minor southwest-directed thrust: (i) the Turó de Montgat Unit composed of litharenites and lithorudites with high contents of quartz, feldspar, plutonic and limestone rock fragments; and (ii) the Pla de la Concòrdia Unit composed of calcilitharenites and calcilithorudites with high contents of dolosparite and dolomicrite rock fragments. The petrological composition of both units indicates that sediments were derived from the erosion of Triassic (Buntsandstein, Muschelkalk and Keuper facies), Jurassic and Lower Cretaceous rocks (Barremian to Aptian in age). Stratigraphic and petrological data suggest that these units correspond to two coalescent alluvial fans with a source area located northwestwards in the adjoining Collserola and Montnegre inner areas. Micromammal fossils (Archaeomys sp.) found in a mudstone layer of the Pla de la Concòrdia Unit assign a Chattian age (Late Oligocene) to the studied materials. Thus, the Montgat deposits are the youngest dated deposits affected by the contractional deformation that led to the development of the Catalan Intraplate Chain. Taking into account that the oldest syn-rift deposits in the Catalan Coastal Ranges are Aquitanian in age, this allows to precise that the change from a compressive to an extensional regime in this area took place during latest Oligocene-earliest Aquitanian times. This age indicates that the onset of crustal extension related to the opening of the western Mediterranean Basin started in southern France during latest Eocene-early Oligocene and propagated southwestward, affecting the Catalan Coastal Ranges and the northeastern part of the Valencia trough during the latest Chattian-earliest Aquitanian times.

Inclusion of soil erosion impacts in life cycle assessment on a global scale: application to energy crops in Spain

Purpose: Despite the fundamental role of ecosystem goods and services in sustaining human activities, there is no harmonized and internationally agreed method for including them in life cycle assessment (LCA). The main goal of this study was to develop a globally applicable and spatially resolved method for assessing land-use impacts on the erosion regulation ecosystem service.Methods: Soil erosion depends much on location. Thus, unlike conventional LCA, the endpoint method was regionalized at the grid-cell level (5 arc-minutes, approximately 10×10 km2) to reflect the spatial conditions of the site. Spatially explicit characterization factors were not further aggregated at broader spatial scales. Results and discussion: Life cycle inventory data of topsoil and topsoil organic carbon (SOC) losses were interpreted at the endpoint level in terms of the ultimate damage to soil resources and ecosystem quality. Human health damages were excluded from the assessment. The method was tested on a case study of five three-year agricultural rotations, two of them with energy crops, grown in several locations in Spain. A large variation in soil and SOC losses was recorded in the inventory step, depending on climatic and edaphic conditions. The importance of using a spatially explicit model and characterization factors is shown in the case study.Conclusions and outlook: The regionalized assessment takes into account the differences in soil erosion-related environmental impacts caused by the great variability of soils. Taking this regionalized framework as the starting point, further research should focus on testing the applicability of the method trough the complete life cycle of a product and on determining an appropriate spatial scale at which to aggregate characterization factors, in order to deal with data gaps on location of processes, especially in the background system. Additional research should also focus on improving reliability of the method by quantifying and, insofar as it is possible, reducing uncertainty.

Alzheimer disease diagnosis based on automatic spontaneous speech analysis

Alzheimer’s disease (AD) is the most prevalent form of progressive degenerative dementia and it has a high socio-economic impact in Western countries, therefore is one of the most active research areas today. Its diagnosis is sometimes made by excluding other dementias, and definitive confirmation must be done trough a post-mortem study of the brain tissue of the patient. The purpose of this paper is to contribute to im-provement of early diagnosis of AD and its degree of severity, from an automatic analysis performed by non-invasive intelligent methods. The methods selected in this case are Automatic Spontaneous Speech Analysis (ASSA) and Emotional Temperature (ET), that have the great advantage of being non invasive, low cost and without any side effects.

Anàlisi socioambiental dels voltors a Alinyà : evolució, percepció i viabilitat

La finca de la Muntanya d’Alinyà és l’única zona del món on es poden observar les quatre espècies de voltors europeus: voltor comú (Gyps fulvus), voltor negre (Aegypius monachus), aufrany (Neophron percnopterus) i trencalòs (Gypaetus barbatus). Davant el problema de l’abandonament del poble i de l’envelliment de la població es planteja una alternativa de futur vers a una economia no tant basada en la ramaderia i l’agricultura, que són les activitats agropecuàries tradicionals a la zona. La recent intervenció de la Fundació Territori i Paisatge ha determinat, en gran part, el futur d’aquestes aus a Alinyà. Per una altra banda, les normatives vigents eren molt restrictives, fins fa ben poc, sobre l’aprofitament per part dels voltors de les restes d’animals morts provinents de la ramaderia. Ara neix una nova perspectiva de futur de tipus turístic.

Stratigraphy and petrology of the Miocene Montjuic delta: (Barcelona, Spain).

The Neogene rift in the Catalan Coastal Ranges, which is located in the NE part of the Eastern Iberian Margin, corresponds to a system of grabens formed at the nort h - we s t e rn edge of the Valencia Trough. In the central part of the Catalan Coastal Ranges are the Valls - Peneds half-graben in the onshore and the Barcelona half-graben in the offshore, which are separated by the Garraf and the Collserola-Montnegre horsts. Montjuc hill is a tilted block, which is located to the S of the Barcelona city, between the Collserola-Montn egre horst and the Barcelona half-graben . The Middle Miocene section of Montjuc is constituted by an alternation of conglomerate, sandstone, mudstone and marlstone beds. The Montjuc section was divided into four lithostratigraphic units from base to top: (1) The Morrot conglomerate and sandstone Unit, interpreted as delta plain deposits; (2) the Castell conglomerate, sandstone and mudstone Unit considered as proximal delta front deposits; (3) the Miramar marlstone Unit attributed

Efficacy and safety of once-daily aclidinium in chronic obstructive pulmonary disease

Background: The long-term efficacy and safety of aclidinium bromide, a novel, long-acting muscarinic antagonist, were investigated in patients with moderate to severe chronic obstructive pulmonary disease (COPD). Methods: In two double-blind, 52-week studies, ACCLAIM/COPD I (n = 843) and II (n = 804), patients were randomised to inhaled aclidinium 200 μg or placebo once-daily. Patients were required to have a postbronchodilator forced expiratory volume in 1 second (FEV1)/forced vital capacity ratio of ≤70% and FEV1 <80% of the predicted value. The primary endpoint was trough FEV1 at 12 and 28 weeks. Secondary endpoints were health status measured by St George"s Respiratory Questionnaire (SGRQ) and time to first moderate or severe COPD exacerbation. Results: At 12 and 28 weeks, aclidinium improved trough FEV1 versus placebo in ACCLAIM/COPD I (by 61 and 67 mL; both p < 0.001) and ACCLAIM/COPD II (by 63 and 59 mL; both p < 0.001). More patients had a SGRQ improvement ≥4 units at 52 weeks with aclidinium versus placebo in ACCLAIM/COPD I (48.1% versus 39.5%; p = 0.025) and ACCLAIM/COPD II (39.0% versus 32.8%; p = 0.074). The time to first exacerbation was significantly delayed by aclidinium in ACCLAIM/COPD II (hazard ratio [HR] 0.7; 95% confidence interval [CI] 0.55 to 0.92; p = 0.01), but not ACCLAIM/COPD I (HR 1.0; 95% CI 0.72 to 1.33; p = 0.9). Adverse events were minor in both studies. Conclusion: Aclidinium is effective and well tolerated in patients with moderate to severe COPD. Trial registration: ClinicalTrials.gov: NCT00363896 ACCLAIM/COPD I) and NCT00358436 (ACCLAIM/COPD II).

Neotectonic features in the Catalan Coastal Ranges, Northeastern Spain

The Catalan Coastal Ranges constitute the northwestem emerged sector of the Catalan-Valencian domain of the Valencia trough. Since late Oligocene this domain of the Valencia trough was subjected to extension wich gradually attenuated during later periods. The Miocene tectonic evolution of the Catalan Coastal Ranges is relativelly well known while the Pliocene to-Quaternary stages have not been studied in detail. The recorded seismicity of the area is moderate and constant but not sufficiently intense to cliaracterize and locate recent tectonics. However, geological analysis provides further information. A morphotectonic and deformational analysis of the Catalan Coastal Ranges is presented in this paper.

Cenozoic evolution of eastern Iberia: structural data and dynamic model.

Iberia underwent intraplate deformation during the Mesozoic and Cenozoic. In eastem Ibena, compression took place during the Palaeogene and early Miocene, giving rise to the Iberian Chain, and extension started during the early Miocene in the coastal areas and the Valencia trough; during early Miocene compression continued in the western Iberian Chain whereas extension had started in the eastern Iberian Chain. From the kinematic data obtained from the major compressional and extensional structures formed dunng the Cenozoic, a simple dynamic model using Bott's (1959) formula is presented. The results show that both extension and compression may have been produced assuming a main horizontal stress-axis approximately N-S, in a similar direction that the convergence between Europe, Ibena and Afnca dunng the Cenozoic.

Danza movimiento terapia y abuso sexual

L'organització mundial de la salut, assenyala que la major part de les agressions sexuals tenen com a víctimes a dones i nenes, i són perpetrades per homes i nens. En alguns països, gairebé una de cada quatre dones ha estat víctima de violència sexual per part de la seva parella i fins a una tercera part de les adolescents han sofert una iniciació sexual forçada. Estudis especialitzats fan referència al percentatge de dones que han sofert alguna forma d'abús sexual abans dels 18 anys. En el mateix sentit, enquestes mundials assenyalen que entre el 10% i el 69% de les dones diuen haver estat agredides físicament per una parella masculina en algun moment de la seva vida. La violència sexual infantil provoca a les seves víctimes una sèrie de repercussions i seqüeles, psicològiques, emocionals, socials; compromet el desenvolupament integral de l'individu, i provoca l'aparició d'una sèrie de patologies a l'edat adulta. La present investigació fa una revisió teòrica de la violència sexual, de la violència de gènere, i de les aportacions del procés de recuperació a través de la dansa moviment teràpia d'aquesta població. També es mostra el recorregut del marc d'actuació dels organismes d'ordre públic de la ciutat de Barcelona per a l'atenció i detecció en casos d'abús sexual
