A study of hydrochemical characteristics of the Arbúcies river (a seminatural mediterranean basin) has been undertaken during 1991. Mean solute yield for each ion has been determined using the correlation curves between discharge and concentration, and the flow duration curve. The hydrochemical budget of the Arbúcies drainage basin shows that the basin is a net source for al1 the elements. The cationic denudation rate obtained in this granitic basin is 5.24 keqhalyear. This high rate is due to the intensive chemical weathering of the granodionte, that delivers an important amount of cations which will release to be transported. The results demostrate clearly the strength of lithological control on stream loads, particulary on the dissolved component.

L'avinguda al Barranco de Arás a la vall de Biescas és un esdeveniment hidrològic de caràcter extrem de tipus catastròfic, amb un període de recurrència superior als 1000 anys. Es va produir com a conseqüència d'una tempesta plujosa associada al pas d'un front fred pel Pirineu central el 7 d'agost de 1996. La tempesta va descarregar 200 mm h-1 al fons de la vall de Biescas i 500 mm h-1 a Betés, el nucli de la tempesta, quantitats que corresponen a períodes de recurrència aproximats de 100 i 500 anys respectivament.

The theoretical aspects and the associated software of a bioeconomic model for Mediterranean fisheries are presented. The first objective of the model is to reproduce the bioeconomic conditions in which the fisheries occur. The model is, perforce, multispecies and multigear. The main management procedure is effort limitation. The model also incorporates the usual fishermen strategy of increasing efficiency to obtain increased fishing mortality while maintaining the nominal effort. This is modelled by means of a function relating the efficiency (or technological progress) with the capital invested in the fishery and time. A second objective is to simulate alternative management strategies. The model allows the operation of technical and economic management measures in the presence of different kind of events. Both deterministic and stochastic simulations can be performed. An application of this tool to the hake fishery off Catalonia is presented, considering the other species caught and the different gears used. Several alternative management measures are tested and their consequences for the stock and economy of fishermen are analysed.

Nowadays Scanning Electron Microscopy (SEM) is a basic and fundamental tool in the study of geologic samples. The collision of a highlyaccelerated electron beam with the atoms of a solid sample results in theproduction of several radiation types than can be detected and analysed byspecific detectors, providing information of the chemistry and crystallography ofthe studied material. From this point of view, the chamber of a SEM can beconsidered as a laboratory where different experiments can be carried out. Theapplication of SEM to geology, especially in the fields of mineralogy andpetrology has been summarised by Reed (1996).The aim of this paper is to showsome recent applications in the characterization of geologic materials.

This paper describes petrologic and morphologic characteristics of fossil beaches submerged in the sector of the Costa Brava located between the Pals Beach and Blanes (Girona). These submerged beaches are composed of large-grain sandstone andconglomerate platforms, situated at a depth between 0.5 and 2.5 meters. These platforms are slightly inclinated towards the open sea. These deposits have been formed very recently, and date from Holocene, as noted by the presence of fragments of roman ceramics inside sandstone

Evidence on trends in prevalence of disease and disability can clarify whether countries are experiencing a compression or expansion of morbidity. An expansion of morbidity as indicated by disease have appeared in Europe and other developed regions. It is likely that better treatment, preventive measures and increases in education levels have contributed to the declines in mortality and increments in life expectancy. This paper examines whether there has been an expansion of morbidity in Catalonia (Spain). It uses trends in mortality and morbidity from major causes of death and links of these with survival to provide estimates of life expectancy with and without diseases and functioning loss. We use a repeated cross-sectional health survey carried out in 1994 and 2011 for measures of morbidity; mortality information comes from the Spanish National Statistics Institute. Our findings show that at age 65 the percentage of life with disease increased from 52% to 70% for men, and from 56% to 72% for women; the expectation of life unable to function increased from 24% to 30% for men and 40% to 47% for women between 1994 and 2011. These changes were attributable to increases in the prevalences of diseases and moderate functional limitation. Overall, we find an expansion of morbidity along the period. Increasing survival among people with diseases can lead to a higher prevalence of diseases in the older population. Higher prevalence of health problems can lead to greater pressure on the health care system and a growing burden of disease for individuals.

On the 50th anniversary of the creation of the Federation of Benedictine Women’s Monasteries of Catalonia (Spain), the five monasteries represented are discussing the following question: what will monastic life be like in the future? This question is added to the debate about “new forms of monasticism”, “urban monastic life” and, in a more general sense, to the modernisations and “the opening up” of the precepts and practices of monastic life at this time. Faced with the ambitious monastic questioning, the author responds with five deliberately provocative debates developed out of a consideration of various chapters of the Rule of St. Benedict that raise profound questions when it comes to responding to the question presented here. Having described these five debates, by way of a summary, the article presents three ideal types of monastery in relation to the current processes of deinstitutionalisation that represent, in an overall way, three provisional responses and serve as a focus for the question discussed here.

Climate change may pose challenges and opportunities to viticulture, and much research has focused in studying the likely impacts on grapes and wine production in different regions worldwide. This study assesses the vulnerability and adaptive capacity of the viticulture sector under changing climate conditions, based on a case study in El Penedès region, Catalonia. Farm assets, livelihood strategies, farmer-market interactions and climate changes perceptions are analysed through semi-structured interviews with different types of wineries and growers. Both types of actors are equally exposed to biophysical stressors but unevenly affected by socioeconomic changes. While wineries are vulnerable because of the current economic crisis and the lack of diversification of their work, which may affect their income or production, growers are mainly affected by the low prices of their products and the lack of fix contracts. These socioeconomic stressors strongly condition their capacity to adapt to climate change, meaning that growers prioritize their immediate income problems, rather than future socioeconomic or climate threats. Therefore, growers undertake reactive adaptation to climate changing conditions, mainly based on ancient knowledge, whilst wineries combine both reactive and anticipatory adaptation practices. These circumstances should be addressed in order to allow better anticipatory adaptation to be implemented, thus avoiding future climate threats.

Between late spring and early fall, the development of storms is common in Catalonia. Despite the fact that they usually produce heavy showers of short duration, they can also involve severe weather with ice pellets or hail. While the latter usually affect inland regions, and there are numerous publications on these cases; the analysis of events affecting the coast and causing damage to public and private properties is not so well developed. The aim of this study is to provide additional thermodynamic indicators that help differentiate storms with hail from storms without hail, considering cases that have affected various regions of Catalonia, mainly coastal areas. The aim is to give more information to improve prognosis and the ability to detail information in these situations. The procedure developed involved the study of several episodes of heavy rainfall and hail that hit Catalonia during the 2003-2009 period, mainly in the province of Girona, and validated the proposal during the campaign of late summer and fall of 2009, as well as 2012. For each case, several variables related to temperature, humidity and wind were analyzed at different levels of the atmosphere, while the information provided by the radio sounding in Barcelona was also taken into account. From this study, it can be concluded that the temperature difference between 500 hPa and 850 hPa, the humidity in the lower layers of the atmosphere and the LI index are good indicators for the detection of storms with associated hail.
