L'Origen de l'arquitectura en pedra i l'urbanisme a la Catalunya Occidental

The consolidation of an agricultural economy based in extensive cereals production influenced the development of the typical communities of the plains of western Catalonia during the second millennium BC and the first centuries of the first and differentiated them from the villages of the coast. This paper analyzes the occupation and exploitation pattems of temtories, settlements and specially the development of stone architecture in the Bronze and Iron Age periods. We characterise the process that leads from the first open-air sedentary settlements to the agricultural settlements in early and middle Bronze Age period and the appearance of wellbuilt houses and town planning during the late Bronze Age. We can asses the contribution of the early Urnfield period and link the kind of settlement, the town plan, the architecture and building techniques - which centuries later characterised the Ibero-Ilergeta society - to their origin during the later Urnfield period: systematic exploitation of lands suitable for agriculture (Urgell, Monegros), the phenomenon of concentration-depopulation and the decrease in number of settlements combined with an increase in size.

Magnitud y frecuencia del transporte fluvial de sedimento en una cuenca mediterránea semihúmeda

Este trabajo examina la magnitud y la frecuencia del transporte de sedimento (material disuelto, sedimento en suspensión y carga de fondo) en la cuenca de la riera de Arbúcies (Cordilleras Costeras Catalanas), a partir de los caudales diarios del periodo 1967-1992 y de las muestras de agua y sedimento obtenidas durante los años 1991 y 1992. Los resultados indican que el transporte en disolución es más uniforme en el tiempo que el transporte de material sólido, tanto en suspensión como de fondo. Los cálculos muestran que la carga sólida total depende sobre todo de crecidas frecuentes y de magnitud moderada, correspondientes al nivel de cauce lleno (bankfull). Cabe señalar, en este sentido, que los caudales bankfull suceden el 2,2% del tiempo y transportan el 56% del sedimento en suspensión y el 31% de la carga de fondo total anual. El caudal efectivo para el transporte de sedimento en este río es, por tanto, un suceso relativamente frecuente y de idéntica magnitud al caudal geomorfológicamente dominante o bankfull.

Short communication. Potential to mitigate anthropogenic CO2 emissions by tillage reduction in dryland soils of Spain

Spain is one of the countries with the highest greenhouse gas (GHG) emissions within the EU-27. Consequently, mitigation strategies need to be reported and quantified to accomplish the goals and requirements of the Kyoto Protocol. In this study, a first estimation of the carbon (C) mitigation potential of tillage reduction in Mediterranean rainfed Spain is presented. Results from eight studies carried out in Spain under rainfed agriculture to investigate the effects of no-tillage (NT) and reduced tillage (RT) compared with conventional tillage (CT) on soil organic carbon (SOC) were used. For current land surface under conservation tillage, NT and RT are sequestering 0.14 and 0.08 Tg C yr-1, respectively. Those rates represent 1.1% and 0.6% of the total CO2 emissions generated from agricultural activities in Spain during 2006. Alternatively, in a hypothetical scenario where all the arable dryland was under either NT or RT management, SOC sequestration would be 2.18 and 0.72 Tg C yr-1 representing 17.4% and 5.8% of the total 2006 CO2 equivalent emissions generated from the agricultural sector in Spain. This is a significant estimate that would help to achieve GHG emissions targets for the current commitment period of the Kyoto Protocol.

Corrección de cauces torrenciales

Las cuencas torrenciales presentan una respuesta hidrológica caracterizada por avenidas súbitas y violentas, que transportan grandes cantidades de material sólido, pudiendo afectar gravemente a las infraestructuras de áreas dominadas. En España, la torrencialidad se manifiesta, fundamentalmente, en torrentes de alta montaña y en las ramblas o rieras mediterráneas. En el presente artículo, se pretende exponer brevemente las pincipales técnias de corrección de cauces torrenciales, incidiendo especialmente en el control y la gestión del caudal sólido.

Otolith shape analysis as a tool for population discrimination of the white grunt (Haemulon plumieri) stock in the northern coast of the Yucatan Peninsula, Mexico

In this study, the population structure of the white grunt (Haemulon plumieri) from the northern coast of the Yucatan Peninsula was determined through an otolith shape analysis based on the samples collected in three locations: Celestún (N 20°49",W 90°25"), Dzilam (N 21°23", W 88°54") and Cancún (N 21°21",W 86°52"). The otolith outline was based on the elliptic Fourier descriptors, which indicated that the H. plumieri population in the northern coast of the Yucatan Peninsula is composed of three geographically delimited units (Celestún, Dzilam, and Cancún). Significant differences were observed in mean otolith shapes among all samples (PERMANOVA; F2, 99 = 11.20, P = 0.0002), and the subsequent pairwise comparisons showed that all samples were significantly differently from each other. Samples do not belong to a unique white grunt population, and results suggest that they might represent a structured population along the northern coast of the Yucatan Peninsula

Effects of prolonged ethanol intake and malnutrition on rat pancreas

Nutritional factors, especially the protein and fat content of the diet, may change pancreatic morphology after ethanol induced injury. This study was performed to delineate the combined effects of a low fat diet and longterm ethanol ingestion on the rat pancreas. Male Sprague-Dawley rats were maintained with five different diets for 12 weeks and the pancreas removed on the day they were killed. Rats fed a very low fat diet without ethanol (5% of total calories as lipid) developed malnutrition, pancreatic steatosis, and reduction in zymogen granules content. Animals fed a 35% lipid diet with ethanol also developed pancreatic steatosis but changes in zymogen granules content were not detected. Both malnutrition and longterm ethanol consumption increased pancreatic cholesterol ester content, and their effects were additive. Pancreatic steatosis was accompanied with hypercholesterolaemia. Amylase, lipase, and cholesterol esterase content were reduced in malnourished rats; but longterm ethanol ingestion, regardless of the nutritional state, increased lipase content and decreased amylase. It is suggested that high serum cholesterol concentrations and increased pancreatic lipase activity could cause accumulation of cholesterol esters in acinar cells. Fat accumulation in the pancreas has been reported as the earliest histopathological feature in alcoholic patients and may be responsible for cytotoxic effects on the acinar cells at the level of the cell membrane. Although it is difficult to extrapolate results in this animal study to the human situation, the results presented in this work might explain the higher incidence of pancreatitis is malnourished populations as well as in alcoholic subjects that is reported in dietary surveys.
