A long-snouted late Eifelian arthrodire from Aragon (Spain)
2021
Carolowilhelmina geognostica Carls, 1995 is a large arthrodire (Placodermi) from the Tortodus kockelianus Conodont Zone, late Eifelian, in the Eastern Iberian Cordillera in southern Aragon. The somewhat incomplete but articulated skull is preserved, showing a long tubular rostral plate, very small postnasal plates, low toothless inferognathals, and a small, slender and flat parasphenoid. Supraorbital and central sensory lines meet their antimeres at the midline of the skull, forming a straight double line. Lines along the ventral surface of the rostral plate probably belong to the suborbital branches of the infraorbital sensory lines. The combination of characters of Carolowilhelmina points…
Vibrios isolated from the cultured manila clam (Ruditapes philippinarum): numerical taxonomy and antibacterial activities.
2002
Aims: A numerical taxonomic study of halophilic Vibrio isolated from healthy and brown ring disease (BRD) affected manila clams (Ruditapes philippinarum), harvested from the Atlantic coast of south-western Spain, was performed. Methods and Results: Characterization of 123 presumptive Vibrio spp. was carried out using 94 phenotypic tests. Simple matching and Jaccard similarity coefficients were used for numerical analysis. Cluster analysis by the unweighted pair group method with arithmetic averages yielded 15 phena defined at 0.81 similarity. Large phena corresponded to Vibrio tubiashii, V. splendidus biotype I and V. harveyi (phena 1, 5 and 9, respectively). The species V. splendidus bioty…
Comparative evolution of P–M system and infection by the sigma virus in French and Spanish populations ofDrosophila melanogaster
1992
SummaryIn 1983, an extensive survey of populations ofD. melanogasterwas started in a southern French region (Languedoc) in two non-Mendelian systems: the P–M system of transposable elements and the hereditary Rhabdovirus sigma. Unexpectedly fast-evolving phenomena were observed and interesting correlations were noted, giving similar geographical pattern to the region in both systems. For these reasons, the analysis was continued and extended towards the north (Rhône Valley) and the south (Spain). In the P–M system, all the Languedoc populations evolved from 1983 to 1991 towards the Q type which is characteristic of the Rhône Valley populations. In contrast, M′ strains are currently observed…
Las hormigas (Hymenoptera, Formicidae) asociadas a pulgones (Hemiptera, Aphididae) en la provincia de Valencia
2002
Twenty-six species of ants associated with aphids, belonging to twelve genera, are collected. Three subfamilies are identified, being the Formicinae the more represented about number of samples, genera and species. On the other hand, <i>Lasius niger</i> has been the species that is found with a more number of aphids (fifty eight species), and it seems to be the ant with a more capacity to establish associations with the different species of aphids. 224 different associations between the ants and the aphids are established and 164 of them are not recorded in the bibliography consulted for Spain.<br><br>Se han recogido veintiséis especies de hormigas asociadas a pulgon…
Empoderamiento femenino e insersión por la economia: analisis comparativo del modelo de las cooperatias andaluzas y de la economía solidaria en brasil
2017
Cette étude a comme objectif central d’examiner l’hypothèse suivante: les coopératives d’économie sociale et/ou solidaires contribuent à l’autonomisation des femmes en créant des dynamiques d’équité en termes sociaux, économiques et culturels, qui promeuvent l’égalité des sexes. Les principaux objectifs qui guident cette recherche sont les suivants: 1) Aborder les facteurs sociaux, économiques et culturels qui régissent les entreprises sociales prédominantes. Les principaux facteurs sont: le genre, le niveau de scolarité et le rôle des coopératives dans le développement économique et social de chaque pays. 2) Analyser les facteurs que prennent en compte les deux formes de gestion, le systèm…
CAPITAL FLOW BONANZAS AS A FUNDAMENTAL INGREDIENT IN SPAIN'S FINANCIAL CRISES, 1850-2015
2020
El trabajo analiza los mecanismos a través de los cuales los flujos de capital produjeron inestabilidad financiera en España durante un período de 165 años. Se estudia por qué y cómo las bonanzas de capital hacen que las crisis sean más probables y severas, y si su incidencia varía en función de los tipos de crisis (crisis cambiaria, bancaria y de deuda). Concluimos que la mayoría de ellas se produjeron en diferentes regímenes de política monetaria pero que se asociaron a bonanzas de capital en un marco regulatorio liberal, lo que contribuyó a una mayor probabilidad y a una mayor gravedad de las crisis. El análisis de los diferentes regímenes de política monetaria, las estructuras financier…

The direct socioeconomic consequences of the First Carlist War
2018
En este artículo trato de analizar el impacto que la Primera Guerra Carlista tuvo sobre la población y la economía española. Para ello he divido las consecuencias en tres partes: pérdidas humanas, el exilio tras la guerra y los daños materiales. De esta forma he observado que la Primera Guerra Carlista, aunque no tuvo consecuencias graves sobre el conjunto de España, sí que las tuvo sobre las zonas que se vieron más afectadas por los combates. En ellas la guerra dejó un rastro de muertos, heridos, carlistas exiliados, mujeres violadas, viviendas destruidas, bosques talados y ganado exterminado, así como un aumento del endeudamiento municipal y estatal, que a su vez tuvo otras repercusiones.…
Biofiltration of ethylbenzene vapours: influence of the packing material.
2006
In order to investigate suitable packing materials, a soil amendment composed of granular high mineralized peat (35% organic content) locally available has been evaluated as carrier material for biofiltration of volatile organic compounds in air by comparison with a fibrous peat (95% organic content). Both supports were tested to eliminate ethylbenzene from air streams in laboratory-scale reactors inoculated with a two-month conditioned culture. In pseudo-steady state operation, experiments at various ethylbenzene inlet loads (ILs) were carried out. Maximum elimination capacity of about 120 g m(-3) h(-1) for an IL of 135 g m(-3) h(-1) was obtained for the fibrous peat. The soil amendment re…
Use of biological and sedimentation models for designing Peñíscola WWTP.
2004
This paper presents Peñíscola wastewater treatment plant design. Peñíscola is a tourist city in Castellón (Spain), whose population changes significantly between summer and the rest of the year. The design of the biological and settling treatment units has been confirmed by computer model simulations and provided for biological organic matter, nitrogen and phosphorus removal. Two different treatment schemes have been proposed in order to optimize the plant performance during both seasonal operations. During low-load season, the plant will be operated under extended aeration conditions, so further sludge stabilization will not be needed. During high-load season, the plant will be operated un…
