Cabeço de Vide Ophiolite: structure, age and correlation of an obducted marginal basin on the northern margin of Gondwana
No full textThe Cabeço de Vide Ophiolite (SW Iberian Massif) offers new insights into the tectonic evolution of the North Africa Gondwana margin. This study presents petrological, structural, and geochronological evidence to reconstruct the Cadomian tectonic evolution of the Cabeço de Vide Ophiolite and discusses possible correlations. The Cabeço de Vide Massif experienced two Cadomian deformation phases (DC1 and DC2). Besteiros thrust (Besteiros Shear Zone) is attributed to DC1, which obducted the Cabeço de Vide Ophiolite onto the Ediacaran series deposited along the Gondwana margin (top-to-E-NE emplacement). DC2 produced a normal-sense ductile shear zone with top-to-the-SE kinematics (Cabeço de Vide Shear Zone). A cross-sectional data analysis combining geochronological evidence with U-Pb dating in calcite (marbles) and zircon (amphibolites, metagranites and metaconglomerates) constrains the age of DC1 between ca. 623–523 Ma. The same analysis suggests a Cambrian age for DC2, between ca. 523–512 Ma. The sequence, timing and kinematics of the major Cadomian structures in the study area align with those described in other sections of the Cadomian Orogen in Iberia, notably the Calzadilla Ophiolite. We propose a correlation between the Cabeço de Vide and Calzadilla ophiolites, which would emerge as two pieces of a single ophiolitic belt. This ophiolitic belt was probably obducted from a primary fore-arc basin setting inland onto Gondwana during the Cadomian Orogeny. The thrusting of the late Ediacaran ophiolites was followed by the collapse of the arc system, which was accommodated by the development of ductile extensional shear zones during the Cambrian (DC2), accompanied by uplifting, erosion and magmatism.MCIN/AEI/ 10.13039/501100011033Center for Sci-Tech Research in Earth System and Energy-CREATEDepto. de Mineralogía y PetrologíaFac. de Ciencias GeológicasTRUEpu

International statistical classification of diseases and related health problems (11th ed.) https://icd.who.int/.Borderline intellectual functioning (BIF) is defined as a neurodevelopmental condition characterised by an intelligence quotient between 71 and 85, along with difficulties in adaptive functioning. Although individuals with this condition experience various challenges and require support in different areas of life, research on this topic remains limited. Therefore, this article presents a systematic review aimed at describing the cognitive profile of individuals with BIF. The review included studies addressing the intellectual functioning of the BIF population published between 2012 and 2024. The literature search was conducted in the ProQuest, WoS, SCOPUS, and EBSCOhost databases. Finally, a total of 33 articles were included, and their quality was assessed using the SSAHS tool. The results were organised into three categories: general cognitive abilities, executive functions, language cognition, and neurophysiology. The analysis indicates that individuals with BIF exhibit a cognitive profile characterised by deficits in various domains, including executive functions (such as working memory, cognitive flexibility, processing speed, and planning), general cognitive abilities (such as memory, attention, abstract thinking, problem-solving, arithmetic, and concentration), and language-related cognitive skills, both oral and written. Additionally, neuroimaging techniques suggest that BIF is also associated with structural and functional alterations in the brain. The implications and limitations of the study are discussed, as well as the need for future research with larger samples and more comprehensive assessments. Additionally, the necessity of promoting policies and services that include this population is emphasised.Depto. de Investigación y Psicología en EducaciónFac. de EducaciónTRUEpu
The late Ediacaran to early Cambrian subduction-related granitic magmatism of the Pampean orogen: Geochemical and isotopic constraints on hybridization processes
No full textThe late Ediacaran to early Cambrian Pampean magmatic arc in Argentina represents an excellent example of subduction-related magmatism and continental crust formation. This study presents new geochemical, isotopic, and geochronological data from the Guasayán intrusive complex, which is a significant body within this magmatic arc. The data are integrated with a comprehensive compilation of published data from the arc elsewhere. The Pampean arc exhibits a wide range of rocks, from metaluminous I-type diorites to strongly peraluminous S-type granites, with the majority displaying hybrid compositions (mostly magnesian, calc-alkalic and slightly peraluminous compositions). Zircon U-Pb geochronology indicates that the Guasayán granitoids were emplaced mainly during a flare-up of arc magmatism between ca. 530 and 535 Ma. However, the presence of zircon antecrysts with ages of ca. 545 Ma in most of the Pampean arc granitoids, suggests that the magmatic system was long-lived, and the early crystallized zircon crystals were recycled into younger magmatic pulses. Geochemical and isotope data (Sr-Nd-Hf) highlight the interaction between mantle-derived magmas and crustal components, with magma mixing identified as the dominant process in the generation of the hybrid granitoids. Local-scale processes such as crustal assimilation, fractional crystallization, and peritectic entrainment also contributed to the geochemical and isotopic diversity. The involvement of the Puncoviscana Series as the crustal component of the mixed magmas is evidenced by zircon inheritance patterns and isotopic signatures. This study underscores the importance of magma mixing in the evolution of the Pampean arc and provides insights into the geodynamic processes driving continental crust formation in subduction-related settings.Universidad Nacional de CórdobaUniversidad de HuelvaDepto. de Mineralogía y PetrologíaFac. de Ciencias GeológicasTRUEpu
Time response of an undoped LaCl3 crystal
No full text© 2025 The Authors.
CIPROM/2021/064We have characterized a detector equipped with an undoped LaCl truncated cone crystal with dimensions of 22.5 mm in the largest diameter, 16 mm in the smallest diameter, and 16 mm in height, coupled to a fast Photonis XP2020/URQ photomultiplier tube (PMT). Its time response at 511 keV (22Na) and 60Co photon energies has been measured against a reference detector using a fast digitizer module by digital signal processing methods based on a genetic algorithm. The time resolution was optimized by the choice of the photomultiplier bias voltage and the fine-tuning of the digital parameters of the time pickup algorithm. The de-convoluted full width at half maximum (FWHM) time resolution is found to be 250 ± 10 ps at 60Co energies, and 444 ± 8 ps using positron annihilation -rays from 22Na, providing good prospects for the use of the crystal in applications requiring a fast time response.Ministerio de Ciencia e Innovación (España)Agencia Estatal de Investigación (España)European CommissionComunidad de MadridGeneralitat ValencianaDepto. de Estructura de la Materia, Física Térmica y ElectrónicaFac. de Ciencias FísicasInstituto de Física de Partículas y del Cosmos (IPARCOS)TRUEpu
Osmotic stress as an adaptation mechanism of ochratoxigenic moulds in a dry-cured ham model system
No full textCredit authorship contribution statement
Micaela Álvarez: Writing – original draft, Investigation, Formal analysis. Josué Delgado: Writing – review & editing, Methodology, Investigation. Alicia Rodríguez: Writing – review & editing, Supervision, Methodology, Funding acquisition, Conceptualization.New strategies in the dry-cured ham industry advocate reducing NaCl or replacing it with KCl to improve consumer health without compromising safety. We examined the growth, ochratoxin A (OTA) production, and osmoadaptive responses of two common ham-colonising fungi, Penicillium nordicum and Aspergillus westerdijkiae, under four culture conditions: control (no added salt), 100 g/L NaCl, 100 g/L KCl, and 50 g/L each of NaCl + KCl. Media were based on lyophilized dry-cured ham, and strains were incubated at 25 degrees C for 12 days. High adaptation to salt-rich conditions was demonstrated by the faster development of both moulds in salt-supplemented media, with A. westerdijkiae exhibiting overall higher growth and OTA production. The unsupplemented control medium produced the greatest OTA levels, indicating that mild osmotic stress may maximise toxin synthesis. Intracellular glycerol assays revealed HOG-pathway activation in A. westerdijkiae under salt stress, whereas P. nordicum showed reduced glycerol accumulation, implying alternative adaptation routes. Free-chlorine release occurred via OTA and free chlorine in both species, though no direct correlation with OTA levels was found. Total NaCl replacement by KCl did not significantly alter OTA synthesis, suggesting feasibility for sodium reduction in dry-cured ham. However, partial NaCl substitution may risk elevated OTA production by A. westerdijkiae. These species-specific findings underscore the need for tailored mitigation strategies to ensure food safety in low-sodium dry-cured ham.Ministerio de Economía, Comercio y Empresa ( España)Junta de ExtremaduraEuropean CommissionDepto. de Nutrición y Ciencia de los AlimentosFac. de VeterinariaTRUEpu
Brucellosis in aquatic mammals
No full textThe study of brucellosis in marine mammals has become crucial due to its zoonotic risks and its effects on marine species. The bacteria Brucella ceti and Brucella pinnipedialis cause significant health issues in cetaceans and pinnipeds, respectively. While B. ceti is associated with severe conditions and strandings, B. pinnipedialis often remains asymptomatic, though some cases of disease have been noted. The zoonotic potential of marine Brucella strains, particularly sequence type 27, further emphasizes the need for continuous surveillance and research. While real-time PCR is useful for detecting Brucella DNA, it faces limitations, making it unsuitable for direct application to these samples. Bacterial culture remains the gold standard for diagnosing brucellosis, and molecular techniques should be applied to these cultures to ensure accurate strain identification. Additionally, the limitation of standardized serological tests for all marine mammals species underscores the necessity for developing reliable and accesible diagnostic tools, including ELISAs, to improve diagnostic accuracyDepto. de Sanidad AnimalFac. de VeterinariaTRUEpu
Cambrian initiation of the Saxothuringian Ocean: new insights from the Kaczawa Complex, West Sudetes, Poland
No full textThe Saxothuringian Ocean originated in the Early Palaeozoic from the fragmentation of northern Gondwana. In the Kaczawa basin, a part of the Saxothuringian Ocean, sedimentary-volcanogenic deposition began during the early Cambrian. The clastic material, predominantly composed of Neoproterozoic (c. 75 %) detrital zircons, originated from source areas dominated by 0.64–0.60 Ga and 0.58–0.54 Ga-aged felsic rocks, formed within a continental magmatic arc along the Gondwanan margin. This Ediacaran magmatism facilitated the recycling of older Gondwanan crust, which incorporated Cryogenian (0.75–0.73 Ga), Tonian-Stenian (1.2–0.9 Ga), Paleoproterozoic (2.2–1.8 Ga), and Archean (3.4–2.4 Ga) components. These inputs are reflected in εHf(t) values (–35.0 to +12.8) and TDM(Hf) ages (2.6–0.7 Ga), indicating a complex structure of the Gondwanan margin. The older continental crust of this margin gained juvenile additions from the mantle around 1.0 Ga and 0.72–0.53 Ga, supported by positive Hf zircon and whole rock Nd isotopic evidence. Though absent in the Kaczawa Complex today, such rocks were likely eroded alongside volcanic ash falls during the Cambrian. Detritus is interpreted to be transported from the Saharan Metacraton, the Trans-Saharan Belt, and the Anti-Atlas domain, shaped by the drainage systems of northern Gondwana. Contributions from the West African Craton cannot be ruled out, but the source regions exhibit greater complexity than this single craton. Mafic volcanism, ranging from WPB to OIB types with TDM(Nd) ages of 0.72–0.53 Ga began in the early Cambrian. This was accompanied by intermediate volcanic differentiates (TDM(Nd) 0.7–0.5 Ga) and felsic effusives (TDM(Hf, Nd) ages of 1.2–0.9 Ga), with volcanic activity peaking 500–490 Ma. This early evolution of the Kaczawa Complex reflects a continental rift-back arc basin system linked to oceanic subduction beneath the extended Gondwanan margin. This setting involved mantle wedge melting, differentiation and contamination by subducted sediments and materials from the upper plate.National Science Center, PolandDepto. de Mineralogía y PetrologíaFac. de Ciencias GeológicasCAI Ciencias de la Tierra y ArqueometríaTRUEpu
Extremadura y sus masculinidades, un sentimiento a la busca de su forma. La construcción de la identidad masculina de los obreros migrantes extremeños (1973-1993)
No full textTesis inédita de la Universidad Complutense de Madrid, Facultad de Bellas Artes, leída el 24/05/2024Extremadura y sus masculinidades, un sentimiento a la busca de su forma. La construcción de la identidad masculina de los obreros migrantes extremeños (1973-1993) aborda los efectos que provocó el gran éxodo rural de la segunda mitad del siglo XX en la identidad varonil de los emigrantes extremeños. Entre la década de los 50 y los años de la Transición, las zonas rurales del Estado español entraron en un proceso de declive poblacional, en el que la mayor parte de sus habitantes se trasladaron en masa a los centros industriales del país. Este éxodo —que ha sido calificado de traumático por varios estudios— tuvo unas consecuencias devastadoras. Por una parte, las zonas de recepción multiplicaron varias veces su número de moradores, lo que supuso el nacimiento de amplios poblados chabolistas y de polígonos de vivienda construidos en masa. Al mismo tiempo, las zonas agrarias de origen se fueron vaciando, quedándose sin su población más joven y en edad de trabajar...Extremadura and its masculinities, a feeling in search of its form. The construction of the male identity of Extremadura’s migrant workers (1973-1993) explores the effects of the rural exodus of the second half of the 20th century on the masculine identity of Extremadura’s emigrants. During the period between the 1950s and the Spanish Transition, the rural areas of Spain entered a process of population decline, in which most of its inhabitants moved en masse to the industrial centers of the country. This exodus —which has been described as traumatic by several studies— had devastating consequences. On one hand, the number of people living in the reception areas increased many times over, which led to the creation of large shanty towns and mass housing projects. On another hand, the original agricultural areas were emptied of their youngest and working-age population...Fac. de Bellas ArtesTRUEunpu
