Se analizaron un total de 342 muestras de lomo de diferentes razas (100 % ibérico, 50 % ibérico, Large White español x Landrace y Duroc canadiense), sistemas de producción y dietas. Las propiedades físicas se evaluaron utilizando muestras asadas a la parrilla y cocidas en agua, que se evaluaron en caliente o tras enfriarlas, respectivamente, y registrando la fuerza de cizallamiento máxima y la energía requerida (trabajo). Los protocolos de preparación y la geometría de la sonda influyen de manera decisiva en los resultados de textura. La prueba BMORS aplicada a muestras frías demostró una alta sensibilidad a la hora de discriminar entre genotipos. El método BMORS en frío, que es rápido y fácil de realizar, mostró correlaciones similares o incluso superiores con los atributos sensoriales de textura en comparación con las otras técnicas. 2026-01-01T00:00:00Z http://hdl.handle.net/10366/170872 [EN]This dataset contains labeled image patches extracted from Colombian Whole Slide Images (WSIs) of conventional Papanicolaou (Pap) tests.

THz technology is of great interest due to its specific properties. Many materials, such as paper and plastic, are transparent to this radiation, enabling inspection and security operations. Many substances have a 'fingerprint' (a characteristic spectrum) in the THz range, making THz radiation a powerful tool for spectroscopic applications. Due to its low photon energy (approximately one million times lower than X-rays), THz radiation is non-ionising and therefore poses no danger to humans. This research project aimed to develop, demonstrate and prepare for transfer a new THz detector prototype capable of competing effectively with existing technologies. The new system was designed modularly so that sensor chips manufactured using different technologies can be employed. In particular, the project has employed two cutting-edge technologies: silicon FinFET transistors and graphene-based transistors. The detection process uses two transistors and is based on plasmon oscillation in a two-dimensional electronic system within an FET channel. This enables EM radiation in the terahertz range to be detected, in accordance with the Dyakonov–Shur theory. These sensors offer several advantages: low cost; a faster response time than other detectors (e.g. bolometers and pyroelectrics); operation at room temperature; scalability; integration into CMOS silicon technology for FinFETs; and compatibility with graphene-based transistors. Graphene field-effect transistors (GFETs), which were developed at the USAL, are highly attractive for THz applications thanks to their high channel mobility (over 100,000 cm²/Vs at room temperature) and efficient light-matter interaction. GFETs have been fabricated with various types of integrated antenna to improve responsivity. FinFETs constitute the latest generation of commercial transistors with ultra-short gate topology, making them excellent candidates for building THz detectors that are almost ready for the market, with the potential for integration of read-out circuitry. The devices were measured in the 0.15–5 THz range and between 4 and 300 K. In particular, the figures of merit, responsivity and NEP (noise equivalent power), were determined. 2026-01-01T00:00:00Z http://hdl.handle.net/10366/170079 [EN]This dataset contains an integrated forest, climate and satellite-derived database for Spain based on Spanish National Forest Inventory, Copernicus and NASA data.

The participants were 369 elementary school students. We used four videos showing a teacher presenting two texts (narrative or descriptive) in two conditions of enthusiasm (high or neutral). A MANOVA revealed additive effects due to enthusiasm and text type on motivation and achievement, but no interaction. Mediation analyzes indicated that enthusiasm showed direct and indirect effects through motivation only for descriptive text. Therefore, the motivational mediation between teacher enthusiasm and student achievement could be especially important when the text is descriptive. 2026-01-01T00:00:00Z http://hdl.handle.net/10366/169754 [ES]Objetivos: El objetivo principal de la investigación fue evaluar si un programa integral de entrenamiento de memoria, diseñado originalmente para personas mayores sanas, es igualmente efectivo en individuos con deterioro de memoria grave.

Sin embargo, pocos estudios han abordado su influencia sobre la satisfacción del alumnado en contextos de aprendizaje relacionados con la divulgación científica. Analizamos la influencia del aprendizaje autorregulado (motivación y estrategias de aprendizaje) en la satisfacción de estudiantes universitarios con la preparación de un artículo de divulgación científica en grupo. Participaron 83 estudiantes universitarios que completaron un cuestionario de aprendizaje autorregulado (MSLQ) y dos cuestionarios ad hoc que evaluaban la satisfacción con el trabajo de divulgación (interacción grupo y contenido). Los resultados mostraron niveles altos de satisfacción con la interacción y el contenido del trabajo de divulgación, mostrando valores promedio superiores a ocho sobre diez. Además, respecto a las dimensiones de aprendizaje autorregulado analizadas, se observó que la motivación influyó en la satisfacción con el contenido del trabajo en los estudiantes con un menor uso de estrategias de aprendizaje. Se discuten las implicaciones de los resultados en el contexto educativo. 2025-01-01T00:00:00Z http://hdl.handle.net/10366/169220 [EN]This dataset contains primary data collected from a sample of 1,006 university students at the University of Salamanca (Spain) during the post-pandemic recovery period.

To achieve this objective, we develop an innovative socio-ecological grand ensemble that combines climate, hydrological, and mi-croeconomic ensemble experiments with a widely used deci-sion support system for water resource planning and manage-ment. Each system is populated with multiple models (multi-model), which we use to evaluate the impacts of multiple cli-mate scenarios and policies (multi-scenario, multi-forcing) across systems so as to identify plausible futures where wa-ter management policies meet or miss their objectives and to explore potential tipping points. The application of the meth-ods is exemplified by a study conducted in the Douro River basin (DRB), an agricultural basin located in central Spain. Our results show how marginal climate changes can trigger non-linear water allocation changes in the decision support systems (DSSs) and/or non-linear adaptive responses of ir-rigators to water shortages. For example, while some irriga-tors barely experience economic losses (average profit and employment fall by < 0.5 %) under mild water allocation re-ductions of 5 % or lower, profit and employment fall by up to 12 % (∼ 24 ×) when water allocation is reduced by 10 %or less (∼ 2×). This substantiates the relevance of informing the potential natural and socio-economic impacts of adapta-tion strategies and related uncertainties for identifying robust decisions. 2024-01-01T00:00:00Z http://hdl.handle.net/10366/169169 [EN]Objectives This study aims to assess the prognostic value of routinely available haematological inflammatory indices—neutrophil-to-lymphocyte ratio (NLR), lymphocyte-to-monocyte ratio (LMR) and platelet-to-lymphocyte ratio (PLR)—for predicting 90-day functional outcome measured by the modified Rankin Scale (mRS) in patients with acute ischaemic stroke treated with reperfusion/recanalisation therapies. A further objective is to integrate these biomarkers with relevant clinical, laboratory and imaging covariates to develop predictive models and to explore whether associations remain consistent across clinically meaningful subgroups (e.g., stroke aetiology, occlusion site and reperfusion success). Conclusions Overall, LMR emerges as a reliable and readily accessible predictor of post-stroke functional outcome following reperfusion-treated ischaemic stroke, with higher LMR values associated with a greater likelihood of a favourable 90-day outcome. By contrast, NLR and PLR show less consistent prognostic performance. Incorporating LMR into multivariable prognostic models may improve risk stratification and support more personalised post-acute care decisions. 2026-01-01T00:00:00Z http://hdl.handle.net/10366/169130 [EN]Lockdown involves social isolation that can have a negative impact at the psychological level, which is why several studies have analyzed the relationship between confinement and possible emotional disorders or alterations. This study aims to analyze the symptoms of posttraumatic stress disorder (PTSD) pertaining to stressors that could appear during the confinement of college students, in addition to their evolution and the differential effects that contagion might cause to these symptoms. 270 students responded to a survey created specifically for this study. The survey was administered once a week during the last four weeks of confinement. The students' responses did not show evidence of PTSD symptoms. Furthermore, the low frequency and intensity of symptoms decreases as the weeks of confinement progress. Likewise, infected students show more symptoms than non-infected students, except in respect of the stressor Fear of contagion. The confinement experienced by our students has not been a source of stress. Although this may seem positive, it also promotes risky behaviors, so it should be considered important to carry out awareness campaigns in order to promote habits that help prevent the transmission of the virus. 2023-01-01T00:00:00Z http://hdl.handle.net/10366/169120 [EN]The consumption of chickpea flour has increased significantly in recent years. The processing of chickpeas into flour produces several co-products that could be reintroduced for human and animal consumption. In this study, two co-products obtained from dry dehulling chickpeas, as a preliminary step to obtaining flour, have been characterized. The proximal composition, fatty acids, amino acids, minerals, B vitamins, bioactive compounds, antioxidant activity, antinutrient composition and techno functional properties of both were analyzed. The product obtained from dehulling, which corresponds to the abrasion of the outer part of the chickpea, showed a nutritional and techno-functional profile similar to that of chickpea flour, with a high protein content, antioxidant capacity and functional properties suitable for food use. The product obtained from the peeler&#39;s aspiration system, consisting of chickpea hulls, is rich in fiber and minerals, especially calcium, with high water retention and firmness of the gel. Both by-products have balanced amino acids and low levels of antinutrients, making them promising sustainable ingredients for food formulations. 2026-01-01T00:00:00Z http://hdl.handle.net/10366/168491 [ES]Los datos corresponden a las respuestas de 80 participantes, estudiantes universitarios, a una tarea de asociación léxica y definición de 56 neologismos derivados organizados por sufijos y con distintos grados de transparencia morfológica y frecuencia de uso.
