El ejército romano en Lusitania durante el periodo tardorrepublicano
(2025) Morillo Cerdán, Ángel; Pereira, Carlos S.P.
RESUMEN: Lusitania fue escenario de enfrentamientos militares entre romanos e indígenas y entre distintas facciones políticas romanas ya durante el último siglo de la República. A menudo encontramos datos arqueológicos que no somos capaces de encajar dentro de la sucesión de acontecimientos históricos. Las evidencias arqueológicas sobre la actuación del ejército romano durante el periodo de las guerras lusitanas y de final del siglo II-comienzo del I a.C., son limitadas, mientras se van conociendo más sobre la guerra de Sertorio y las décadas posteriores, en este caso concentradas sobre todo en el estuario del Tajo. La expedición cesariana y el periodo de la guerra civil entre César y los pompeyanos también tuvieron repercusión en este territorio, pero de este periodo conocemos todavía poco y su cultura material está en proceso de definición.

(2024) Madrid, Josefa; Hernández, Fuensanta; Orengo, Juan; Rey Muñoz, Ana Isabel; Martínez-Miró, Silvia; Schiavone, Achille; López, M.J.; Montalbán, A.; Sánchez, C.J.; Pelegrín, A.F.; Gomez Chova, Luis; González Martínez, Chelo; Lees, Joanna
The use of Kahoot as a gamification tool was implemented to improve the teaching process of chemical composition, identification and nutritional value of animal feeds practices, taught from September to December 2020 in the Animal Nutrition subject of the Veterinary Degree at the University of Murcia. Therefore, the objective of this work was to evaluate the students’ satisfaction and usefulness of applying this tool during these practices. The free version of Kahoot platform was used, in which teachers registered and created accounts to generate the quizzes that would be used during the implementation of the activities; while students accessed the platform (from their mobile devices) with the participant role, to perform the proposed tests. Six Kahoot quizzes were conducted for the practices of chemical composition (1), feed microscopy (3), feed labelling study (1), and determination of the nutritional value of feeds (1). The quizzes were developed during the practices in which this educational intervention was carried out, and the students answered questions related to the topic of each practice, accumulating points based on the correct answers and the time used to answer. During this gamification, the teacher can clarify in detail the answers that have been missed. Finally, the platform shows the students who have received the highest score. After the implementation of these practices, an anonymous and voluntary survey was conducted among the students, to get information about their perception of the ease of use, usefulness, and satisfaction of using this intervention. The questionnaire included 8 items: 4 with a Likert scale (from 1 to 4, from least to most) on ease of use, usefulness, satisfaction, and recommendation for using this tool, and 3 other items to indicate whether they had used the tool previously, and in which practice they found it most useful; also, an open-ended question to provide any comment, they wanted to make, was incorporated. Data collection was carried out in paper format, obtaining a total of 97 questionnaires from a universe of 109 students. This represents a confidence level of 99%, with a margin of error of 4.5%. The results obtained shown: the ease of use and support to familiarise yourself with the subject by this tool, reached high levels (3.29±0.785 and 3.29±0.672 points, respectively); highlighting the perceived usefulness for a correct development of the practices (3.65±0.538 points), and even the recommendation of its use (3.63±0.503 points). In addition, the students indicated that the practices where the use of Kahoot had been most useful was in microscopy (81.44%). In conclusion, the implementation of the gamification tool “Kahoot” in the teaching practices of chemical composition, identification, and nutritional value of animal feeds, obtained a positive impact on the perception of the students in relation to the satisfaction and usefulness to improve the development of the practices, in which this teaching intervention was carried out
Assessment of the effectiveness and satisfaction of veterinary students regarding te use of kahoot as a gamification strategy in the practices of feed formulation and farm feeding
(2024) Madrid, Josefa; Orengo, Juan; Hernández, Fuensanta; Martínez-Miró, Silvia; Schiavone, A; Rey Muñoz, Ana Isabel; López, M.J.; Ayala, L.; Ruíz, E.; Pelegrin, A.F.; Gomez Chova, Luis; González Martínez, Chelo; Lees, Joanna
The implementation of Kahoot as a gamification technique was carried out to energize the practical lessons of feed and ration formulation and farm animal feeding, provided from February to May 2021, in the Animal Nutrition course of the Veterinary Degree at the University of Murcia. This study aimed to investigate the utility and the level of students’ satisfaction with respect to the use of this tool during the practices indicated. For this purpose, the free version of Kahoot was used, where teachers created accounts and designed the quizzes that were used in the activities. On the other hand, students logged into Kahoot (using their mobile devices) as participants, to complete the designed tests. A total of six Kahoot quizzes were developed: four focused on feed formulation sessions, covering topics such as linear programming, feed formulation, and practical scenarios for monogastric animals, as well as designing rations for ruminants; and two more dedicated to nutrition in the farm context. These quizzes were integrated into the corresponding practical sessions, allowing students to answer specific questions for each session. The dynamic of participation, rewarded both accuracy and speed of the responses, granting points that were accumulated by the students during the same session. During the gamification activity, the teacher had the opportunity to explain in detail the mistakes performed. At the end of the activity, students who achieved the highest scores were recognized by the platform. To evaluate the perception of ease of use, satisfaction, and utility that students had perceived after carrying out this intervention, a survey with 5 items in a four-point Likert scale (from the less to the most) was conducted: four about the ease of use and satisfaction, 2 in relation to feed formulation practices and 2 for farm feeding practices; and a last one about the utility of the tool. Additionally, another open-ended item was provided for any comment. The survey was carried out at the end of the evaluation anonymously and voluntarily. Data collection was done on paper, obtaining a total of 94 questionnaires out of 109 students. This represents a confidence level of 99%, with a margin of error of 5%. The results showed that, for the feed formulation and rationing practices, the average rating for ease of use and satisfaction were 3.28±0.705 and 3.60±0.532 points, respectively. For the feeding practices developed on the farm, the utility and satisfaction ratings were also very high, reaching 3.28±0.608 and 3.64±0.522, respectively. Moreover, it is worth to highlight that the students' perception on the helped provided by this gamification with the familiarity of this subject was highly recognized (3.79±0.434 points). In conclusion, the implementation of the gamification tool “Kahoot” in teaching feed formulation and rationing practices, and farm animal feeding, achieved very good ratings in relation to the satisfaction and utility of this educational intervention, which could help to boost the teaching of these practices
Student satisfaction with the use of a bird feeding website as a virtual approach to the professional world of Animal Nutrition in the Veterinary Medicine degree: a pilot experience
(2024) Cara Molina, Almudena de ; Rey Muñoz, Ana Isabel; Madrid, Josefa ; Martínez-Miró, Silvia; Hernández, Fuensanta ; Gómez Chova, Luis ; González Martínez, Chelo ; Lees, Joanna
The use of digital tools is an increasingly common practice in higher education. Among the advantages of using online or e-learning resources are possible lifelong training, greater flexibility and autonomous learning. The main objective of this work was to find out the degree of usefulness and satisfaction of the students of the Animal Nutrition subject of the Degree in Veterinary Medicine at the Complutense University of Madrid, on the use of a digital website for learning aspects related to basic nutrition and bird feeding. The free tool “Google Sites” was used to create the website. Various contents were included in different tabs: (1) Initial tab about the use of the page and generalities; (2) The energy and protein needs of the birds to be calculated; (3) It allowed food consumption to be estimated; (4) How the formulation of a feed is carried out. The part of calculating food needs and consumption included different links that directed to an Excel page. Regarding how to formulate the food, two videos were included in which a veterinary nutritionist belonging to a food company related basic aspects and the most frequently used ingredients; and another, which detailed the operation of a ration formulation program, as well as the steps to follow to obtain the final formula. The website address was made available to students prior to the theoretical class in which the related content was taught. Next, a continuous evaluation questionnaire was provided with questions that required calculations and other aspects related to the content of the theoretical class and the website. To evaluate the students' opinion regarding the degree of usefulness for learning and general satisfaction, a survey that included 4 items was used. The survey was based on the Likert scale (1-5 from least to most) and it was prepared using the Google tool. This was sent via e-mail and it was available until the end of the academic year. A total of 30 students answered the questionnaire. Regarding the results, 74% of those surveyed expressed a high degree of satisfaction (positive and very positive evaluations) for the use of this type of methodology. Furthermore, 70% considered that the use of the tool had motivated them in learning the subject; 61% considered it a useful tool for learning the subject and 83% considered they would like other subjects to use this type of tools. In conclusion, the use of websites for teaching Veterinary Animal Nutrition, and specifically content related to calculating needs and formulating rations, achieves a high degree of satisfaction for students and can be a useful tool for the teacher and manage to bring the student closer to the professional world of animal nutrition. However, few students were involved in responding to the satisfaction surveys, so greater implementation would be desirable to have a more precise vision of how the use of this tool can improve learning. This work was carried out as part of an educational innovation project of the ViceRectorate of Quality of the Complutense University of Madrid (Academic Year 21/22; project no. 13).

Mine Rehabilitation of Sulphide-rich Ore Deposits Based on Geomorphic Solutions Coupled with AMD Chemical Stabilization: A Pioneering Project at the Lousal Mine, Portugal
(2025) Relvas, Jorge Manuel; Pinto, Álvaro Manuel; Donoso, Ramon S.; Martins, Mónica; Tejedor Palomino, María; Esbrí Víctor, José María; Lillo Ramos, F. Javier; Pereira, Ana Margarida; Martín Duque, José Francisco; Anderson E. D.; Graham G. E.
The rehabilitation of the sulphide-rich Lousal mine in Portugal is the first case in Europe to combine geomorphic methodologies with geochemical solutions. A new rehabilitation topography was designed and built using the GeoFluv method; a chemical buffering blanket made up of mineral and organic soil layers was extended over a highly contaminated, 1.7 hectares pilot drainage basin, associated with open limestone channels and a widespread endemic vegetation cover was established in the intervening area. The project sought to create synergies between the beneficial effects of each of the rehabilitation actions implemented. Early results strongly suggest sustainability of the created ecosystem, which is fundamental to the economic viability of this solution in future mine reclamation projects. The insights obtained provide new knowledge and methodological innovations that can be extremely useful in current and future green mining scenarios.
The mortgage rate channel of monetary policy transmission: a tale of two countries
(Macroeconomic dynamics, 2025) Luengo Prado, María José; Cooper, Daniel; Garga, Vaishali
We study the mortgage rate channel of monetary policy transmission under two different mortgage regimes by analyzing the United States with primarily long-term fixed-rate mortgages (FRMs) and Spain with mainly annually resetting adjustable-rate mortgages (ARMs). We find a robust transmission of mortgage rate changes to spending in both regimes, with marginal propensities to consume ranging between 0.58–0.67 in Spain and 0.27–0.52 in the United States. Under ARMs, transmission is stronger when rate changes are expected to persist, whereas under FRMs, the effect is larger when rate changes are expected to revert. We further document the important role of mortgage type in shaping the variation in transmission across mortgagors—while the mortgage rate effect is fairly homogeneous across diverse household characteristics under ARMs, it is more heterogeneous under FRMs and largest among potential refinancers.
Robophilia and Device Art in Japan
(2022) Iglesias García, Ricardo; Alsina, P.; Vila, Irma; Tesconi, S.; Soler-Adillon, J.; Mor, E. [Enric]
The peculiar characteristics of artistic creation in Japan and some Asian countries, in industrial developments in the field of engineering, computing, AI and robotics, and the existence of a culture of manga together with the idea of construction of prototypes from a certain artisticcommercial approach, raise the need to deal in depth with the development of robotic art in Japan, especially as a historical reference and as a vision of the future. The permeability between art and design, so complexly posited in the West, does not suffer that categorical distinction in Japan, where the concept of Device Art opens the possibilities of aesthetic experimentation with new technologies towards industrial productions

The cryptogamic cover in the Antarctica: the response to temperature discriminates endemic and cosmopolitan species
(2024) Pintado Valverde, Ana; Raggio Quílez, José; Colesie, Claudia; Beltrán-Sanz, Núria; Green, Thomas George Allan; Aramburu Cuberta, Ana; García Sancho, Leopoldo; Instituto Antártico Chilena (INACH); Scientific Committe of Antarctic Research (SCAR)
The cryptogamic tundra in maritime Antarctica is composed of lichens and mosses of diverse phylogeographic origins. Around half of the total cryptogamic flora is made up of species that are either endemic or cosmopolitan, yet these two groups are at opposite poles of the phylogeographic classification. For cosmopolitan species the maritime Antarctic represents a small part of their global distribution whereas, for endemic species, it constitutes their only available location. The two groups have evolved under dissimilar geographic and environmental conditions and might be expected to show different adaptive potential, having been selected to meet distinct limiting factors. For instance, under a warming scenario, it might be expected that cosmopolitan species will have adaptive advantages compared to the endemic ones. To test this hypothesis, we investigated the response of net photosynthesis to light intensity and temperature for some of the most abundant species of lichens (Himantormia lugubris, Usnea antarctica, Sphaerophorus globosus, Stereocaulon alpinum) and mosses (Andreaea gainii, Sanionia uncinata) belonging to different phylogeographic categories. We used standard CO2-exchange techniques under fully controlled measurement conditions to generate response curves of net photosynthesis to light and temperature. From these, we determined the respective optima obtaining significantly higher values of optimal temperature for the cosmopolitan species. In addition, we recorded the microclimatic conditions when selected species of each phylogeographic category were active in their natural habitats on Livingston Island (South Shetland Islands), using dataloggers and chlorophyll fluorescence monitoring. Both endemic and cosmopolitan species where most of the time active at around 4 ºC but while endemics were active always below 13 ºC, the cosmopolitans showed activity at temperatures up to 25 ºC. In conclusion, although growing well under present environmental conditions, cosmopolitan species (both lichen and mosses) showed a positive response to warmer temperatures that was not detected in the endemics.

El desafío de la narración inmersiva en televisión: estudio de caso del uso de la realidad aumentada en el programa Al Rojo Vivo de laSexta
(2024) Abellán Guzmán, Carolina
Esta comunicación trata sobre el uso narrativo de los elementos de realidad aumentada que hace el programa 'Al Rojo Vivo' de laSexta. Los objetivos son establecer si el presentador y los elementos de realidad aumentada se encuentran en el mismo plano que visualiza el espectador, identificar si el presentador menciona dichos elementos y delimitar la frecuencia de dicha mención y, por último, examinar si existe interacción entre el presentador y el elemento virtual. La metodología se basa en un análisis de contenido cuantitativo desde un paradigma positivista. Los resultados indican que el elemento de realidad aumentada y el presentador se sitúan en el mismo plano en el 97,3% de las veces (261 en total) mientras no lo hacen en el 2,7% de casos (7 en total); que el 75,4% de las veces (201 en total), el presentador no menciona el ítem RA y el 24,6% (66 en total) sí lo hace y, por último, que en el 88,7% de las veces que aparece un elemento virtual no existe interacción entre éste y el presentador (238 en total) mientras en el 11,3 de las ocasiones sí la hay (30 en total). Como conclusiones, los datos revelan una integración aún incompleta de la realidad aumentada como una herramienta narrativa en el programa 'Al Rojo Vivo'. La realidad aumentada en dicho espacio parece haber sido integrada más como un adorno visual que como un recurso efectivo para mejorar la comprensión y la explicación de las noticias. Esta observación subraya la necesidad de reflexionar sobre cómo mejorar la integración de la realidad aumentada para enriquecer la experiencia informativa del espectador.

Can bacterial products reach the brain after alcohol binge drinking?
(2023) Orio Ortiz, Laura; López Valencia, Leticia; Escudero Moreno, Berta; Moya Montes, Marta; García Bueno, Borja
Introduction: Alcohol binge drinking (ABD) induces leaky gut, allowing the entry of lipopolysaccharide (LPS), a bacterial component, to the systemic circulation, activating the innate immune system and inducing neuroinflammation, leading to cognitive and emotional changes. It is unknown whether LPS could reach the brain to exert its functions, although recent evidence suggests that small parts of this LPS, such as Lipid A, could be transported through apolipoproteins in physiological conditions. Here, we studied the presence of Lipid A in its free form or bound to specific apolipoproteins (ApoAI and ApoB) or its receptor TLR4 in prefrontal cortex (PFC) of male and female rats exposed to an ABD model by gavage. Methods: Rats were exposed to intragastric binge ethanol administrations (3 g/kg ethanol (30% w/v), 3 times/day) for 4 days. Free Lipid A, ApoAI, ApoB and TLR4 levels and binding aggregates were measured in the prefrontal cortex (PFC) by western blot and Co-Immunoprecipitation. Results: Lipid A, ApoAI and ApoB were not increased in their free forms in ABD rats compared with controls. However, Lipid A / ApoAI and Lipid A / ApoB ratios were increased after ABD, indicative of the binding of Lipid A with these apolipoproteins, as confirmed by Co-Immunoprecipitation. Additionally, the LPS agonist TLR4, which is a known core element of neuroinflammation, was found increased in its free form in ABD animals. Conclusion: The presence of bacterial products joined to apolipoproteins in the rat PFC suggests that LPS may infiltrate the brain in ABD conditions and could be related to the neuroinflammatory LPS/TLR4 signaling. No sexual differences were found. Current studies are exploring the impact of this Apo-Lipid A binding in ABD-induced emotional/cognitive alterations.
Reelin plasma levels could identify cognitive impairment in Alcohol Use Disorder diagnosed-patients. A negative effect of peripheral APOE4 on Memory/Learning
(2023) Escudero Moreno, Berta; Arias Horcajadas, Francisco; Orio Ortiz, Laura
One of the genetic risk factors recently found to modulate cognition in alcohol consumption is the presence of the ApoE-ε4 allele. ApoE-ε4 allele codes for an aberrant APOE4 protein and there are no studies on the effect of peripheral APOE4 in Alcohol Use Disorder (AUD) patients. Reelin shares the same receptors with APOE4 (ApoER2, VLDLR) and has also been related to cognition in several pathologies. We evaluated APOE4 and Reelin plasma levels and studied their relationship with different cognitive domains in a cohort of abstinent AUD patients. 24 abstinent patients with AUD recruited from an outpatient alcohol program (Hospital Universitario 12 de Octubre, Madrid, Spain) and 34 healthy control subjects were assessed with a validated screening test for AUD, named "Test of detection of cognitive impairment in alcoholism (TEDCA)". The TEDCA identifies the presence of cognitive impairment and provides scores for general intelligence and for three cognitive domains: visuospatial cognition, memory/learning, and executive function. Plasma from patients was obtained in a time-point between 4 and 12 weeks of abstinence. Plasma APOE4 (indicative of APOE4+ carriers) and Reelin were determined by e4Quant patented technique and by Enzyme-Linked Immunosorbent Assay, respectively. We found a negative effect of plasma APOE4 presence (APOE4+) on cognition (general intelligence, memory/learning and executive function) (ANCOVA, p<0.05) and an interaction between AUD disorder and APOE4for memory/learning domain (p<0.05). Reelin was higher in patients and, interestingly, it reached higher plasma levels in patients expressing APOE4, being those with worse cognitive per formance. Reelin identified cognitive deterioration in AUD for general intelligence and executive function (binary logistic regression), explaining 42.8% and 60.0% of the variance of the presence of deficit, respectively. Reelin could be a biological diagnostic tool for early identification of cognitive impairment in AUD pathology. The co-presence of AUD and APOE4+ may favor cognitive impairment in memory/learning.
Plasma levels of ApoE and ApoM identify the presence of absence of cognitive decline in alcohol use disorder patients
(2023) Escudero Moreno, Berta; López Valencia, Leticia; Arias Horcajadas, Francisco; Orio Ortiz, Laura
Some apolipoproteins appear to mediate neuroinflammation and cognitive decline in some neuropsychiatric disorders. Whereas APOE has been related to neuroinflammation, neurodegeneration and cognitive decline in Alzheimer's disease (AD) and Alcohol Use Disorder (AUD), APOAI has shown antiinflammatory properties in AD and no data are available in AUD or in cognition. We evaluated the status of plasma APOAI, APOAII, APOB, APOCII, APOE and APOM in abstinent AUD patients, and their influence in associated cognitive decline. 33 abstinent patients with AUD, recruited from an outpatient alcohol program (Hospital Universitario 12 de Octubre, Madrid, Spain) and 34 healthy control subjects were assessed with a validated screening test for AUD, named "Test of detection of cognitive impairment in alcoholism (TEDCA)". The TEDCA identifies the presence of cognitive impairment and provides scores for general intelligence and for three cognitive domains: visuospatial cognition, memory/learning, and executive function. Plasma apolipoproteins were obtained in a time-point between 4 and 12 weeks of abstinence and determined by Enzyme-Linked Immunosorbent Assay (ELISA) kits in all participants. We found a mismatch in plasma APOAI, APOB, APOE, APOJ and APOM levels between patients and controls, being higher in patients (p<0.05), except for APOM, whose levels were lower (p<0.05). APOE and APOM showed the opposite pattern in patients: whereas upregulated APOE correlated with worse cognitive performance explaining the presence of deficit (almost 50%ofdeficit in memory/learning and 52.8% in EF), downregulated APOM correlated with better cognitive scores and was related to the absence of deficit (identifying >50% of the absence of deficit in general intelligence) (logistic regression models). No associations between the other apolipoproteins and cognitive function were observed. Alterations in several plasma apolipoproteins were observed in AUD patients during abstinence. APOE was identified as a possible damaging factor on AUD's cognition whereas APOM. may have a protective role in these patients
