Endoparasites of the blue whiting, Micromesistius poutassou from north-west Spain.
2005
AbstractThe communities of metazoan endoparasites of blue whiting, Micromesistius poutassou, in waters of north-west Spain were analysed and a geographical comparison made with other localities. Four hundred blue whiting collected in July 1999 and September 2000 were examined for parasites, excluding the head and gills. Six species were found: Anisakis simplex s.l. (L3), A. physeteris (L3), Hysterothylacium aduncum (L2 and L3), Stephanostomum lophii (metacercaria), S. pristis (adult), and Prosorhynchus crucibulum (metacercaria). The latter is a new host record, and A. physeteris is reported for the first time in blue whiting from the north-east Atlantic. Host gender was not a significant pr…
Three species of Magnibursatus Naidenova, 1969 (Digenea: Derogenidae) from Atlantic and Black Sea marine teleosts
2003
Three species of Magnibursatus Naidenova, 1969 are described from marine teleosts: M. skrjabini (Vlasenko, 1931), the type species of the genus, from the gobiid Zosterisessor ophiocephalus on the Bulgarian Black Sea coast; M. bartolii sp. n. from the sparid Boops boops off the Atlantic coast of Spain; and M. minutus sp. n. from the gobiid Neogobius eurycephalus on the Bulgarian Black Sea coast. M. bartolii differs from all other Magnibursatus species in its larger sinus-sac (length >250 µm, width >150 µm) and the more posterior location of testes. This species is also unusual in that it occurs in the branchial chamber and on the gills of its host. M. minutus is distinguished by the distinct…

Growing stock volume from multi-temporal landsat imagery through google earth engine
2019
Growing stock volume (GSV) is one of the most important variables for.forest management and is traditionally- estimated from ground measurements. These measurements are expensive and therefore sparse and hard to maintain in time on a regular basis. Remote sensing data combined with national forest inventories constitute a helpful tool to estimate and map forest attributes. However, most studies on GSV estimation from remote sensing data focus on small forest areas with a single or only a few species. The current study aims to map GSV in peninsular Spain, a rather large and very heterogeneous area. Around 50 000 wooded land plots from the Third Spanish National Forest Inventory (NFI3) were u…
Determination of 3-MCPD by GC-MS/MS with PTV-LV injector used for a survey of Spanish foodstuffs
2007
3-Monochloropropane-1,2-diol (3-MCPD) is the most common chemical contaminant of the group of chloropropanols. It can occur in foods and food ingredients at low levels as a result of processing, migration from packaging materials during storage and domestic cooking. A sensitive method for determination of 3-MCPD in foodstuffs using programmable temperature vaporization (PTV) with large-volume injection (LVI) gas chromatography (GC) with tandem mass spectrometry detection (MS/MS) has been developed and optimized. The optimization of the injection and detection parameters was carried out using statistical experimental design. A Plackett-Burman design was used to estimate the influence of reso…
España inacabada. Organización territorial del Estado, autonomía política y reconocimiento de la diversidad nacional
2021
S’han complert més de tres dècades de vigència de la Constitució de 1978 i, per tant, ja es disposa de prou perspectiva per analitzar el grau d’eficàcia d’un model d’Estat, per alguns, gairebé federal i, per a uns altres, senzillament molt descentralitzat. D’altra banda, a Espanya segueix plenament obert el debat sobre Espanya. Sigui quina sigui l’opinió, la veritat és que el nostre antic problema consumeix una gran part de les energies col·lectives, condiciona àmpliament l’agenda política, genera notables tensions socials i projecta ombres d’incertesa respecte al futur. En aquest treball, s’hi presenta un balanç de les dues qüestions. Després d’oferir un resum breu del procés de construcci…
Results of heart retransplantation: subanalysis of the Spanish Heart Transplant Registry
2021
Heart retransplantation (ReHT) is controversial in the current era. The aim of this study was to describe and analyze the results of ReHT in Spain. Methods We performed a retrospective cohort analysis from the Spanish Heart Transplant Registry from 1984 to 2018. Data were collected on donors, recipients, surgical procedure characteristics, immunosuppression, and survival. The main outcome was posttransplant all-cause mortality or need for ReHT. We studied differences in survival according to indication for ReHT, the time interval between transplants and era of ReHT. Results A total of 7592 heart transplants (HT) and 173 (2.3%) ReHT were studied (median age, 52.0 and 55.0 years, respectively…
A higher incidence of moult–breeding overlap in great tits across time is linked to an increased frequency of second clutches: a possible effect of g…
2021
The rise of temperatures due to global warming is related to a lengthening of the breeding season in many bird species. This allows more pairs to attempt two clutches within the breeding season, thus finishing their breeding activity later in the season and therefore potentially overlapping these with post–breeding moult. We tested whether this occurred in two Spanish great tit Parus major populations. The proportion of pairs laying second clutches increased from 1 % to 32 % over the study period in one of the populations (Sagunto, 1995–2019), while it did not change in the other (Quintos, 2006–2019; mean 5 %). We did not find any temporal trend for moult start date of late–breeding birds i…

On the basis of a decision of the Sicilian Consiglio di Giustizia Amministrativa, the aim of the study is to analyse the criteria developed by the Spanish Tribunal Supremo and Tribunal constitutional and by the French Conseil constitutionnel and Conseil d’Etat on green pass and mandatory vaccination.
Freemasonry and Education in Contemporary Spain. Between Tolerance and Dogmatism
2017
Resumen:En este trabajo vamos a centrarnos casi en exclusiva en las iniciativas planteadas por diversas entidades masónicas, ya sean potencias, logias regionales o talleres, más que en personas exponiendo solamente algunas de las experiencias más relevantes y que ejemplifican mejor las intervenciones y actuaciones de la masonería española en relación con los enfoques descritos. La visibilidad que han alcanzado otras parcelas e interpretaciones del comportamiento, de los masones en particular y de las iniciativas de la masonería como institución, no nos deben ocultar la faceta desarrollada en torno a la educación. ¿Qué importancia tuvo el proceso formativo llevado a cabo en los talleres masó…
