Microclima de cuevas y comportamientos de homeostasis en Ctenomis pearsoni del Uruguay (Rodentia, Octodontidae)

O microclima das tocas do roedor fossorial Ctenomys pearsoni Lessa & Langguth, 1983, foi estudado na zona de Carrasco, Uruguay (34º52'S, 56°04'W). No decorrer de um ano, foram feitas amostragens mensais da temperatura das tocas. Foram obtidas, na comparação com a temperatura exterior, diferenças significativas em dez amostragens (test t., P<0.01 a 0.001); em duas delas, as que correspondem aos meses temperados (março e novembro), não foi observada diferença alguma. A humidade relativa nas tocas é muito elevada (93.34+ou-5.69) e, em relação com a do exterior (69.7+ou-8.34), é significativamente diferente (Kolmogorov Smirnov, P<0.01). Para regulação do micro-clima, Ctenomys pearsoni desenvolve um conjunto de estratégias etológicas que chamamos comportamentos de homeostase. Entre elas destacam-se o permanente fechamento da abertura, a reparação dos danos naturais nos sistemas de galerias e a orientação das entradas preferencialmente em direção oposta ao vento (P<0.05). São estabelecidas algumas considerações sob a importância destes aspectos eco-etológicos em relação com a distribuição geográfica e ecológica dos "tucu-tucus" e seu êxito evolutivo

Challenges in applying human factors approaches to health service design

A participatory systems approach is a fundamental characteristic of the human factors and ergonomics discipline. However, the appropriate application of relevant methods is challenging in healthcare, since there is very limited time for staff to participate and their knowledge on design methods is usually very limited. An action research was carried out in a health service design project commissioned by a local health service commissioner. The aim of this paper is to examine and discuss challenges in applying the participatory systems approach

Effect of the biobased polyols chemical structure on high performance thermoset polyurethane properties

The sustainability of the polymeric materials has become a fundamental challenge; therefore, the development of new biobased formulations has gained increasing interest. Thermoset polyurethanes (PURs) present high performance and are a competitive solution for structural composites. However, polyols used in the PUR synthesis are typically from petrochemical origin. Nowdays, a broad range of biobased polyols is available in the market, but there is not yet a specific formulation for high performance PURs composites. The aim of this work was to study the effect of biobased polyols' characteristics in the PUR processing and final properties. In addition, biobased polyol features to synthesize BIO-PURs suitable for structural applications were stablished. The viscosity and reactivity were studied by means of rheology and differential scanning calorimetry (DSC). Thermal and mechanical properties were studied through thermogravimetric analysis (TGA), dynamic mechanical analysis (DMA) and flexural tests. The results obtained demonstrated the dramatic influence of polyols’ nature on BIO-PUR/PUR properties and their effect on the crosslink density. It was observed that using a high functionality and high hydroxyl index biobased polyol, it was possible to synthesize high performance BIO-PUR suitable for structural composites.We gratefully acknowledge the Basque Government for the financial support through the ELKARTEK 2021 (Project NEOMAT KK-2021/00059) program and in the frame of Grupos Consolidados (IT-1690-22).

Sinergias interuniversitarias en las estrategias didácticas para mejorar la adquisición de competencias en Trabajo Social

Los nuevos planes de estudio de Grado en Trabajo Social ha supuesto un desafío en la formación de las y los estudiantes universitarios que acceden a la titulación. Los procesos de aprendizaje centrado en el alumnado propuestos por el Espacio Europeo de Educación Superior, implican la necesidad de dotar de contenido y sentido al papel protagónico de las y los estudiantes en la adquisición de competencias. El presente artículo recoge los resultados de los trabajos de investigación que viene desarrollando la Red Interuniversitaria Para la didáctica en Trabajo Social (REDITS) constituida por docentes del Grado en Trabajo Social de las universidades de Alicante, País Vasco, Complutense de Madrid, con la incorporación este año de la laurea in Servizio Sociale della Università degli Studi di Torino y la participación de un alumno de tercer curso del Grado. El trabajo desarrollado avanza en la identificación de diversas estrategias para mejorar la adquisición de competencias a la vez que identifica necesidades y grados de satisfacción de las y los estudiantes en el proceso de enseñanza- aprendizaje. Se incorpora también un trabajo de análisis desde un marco teórico referencial sobre las innovaciones en el ámbito de la didáctica

PRECIPITATION STRENGTHENING PRODUCED BY THE FORMATION IN FERRITE OF Nb CARBIDES

A Nb microalloyed steel has been thermomechanically processed at laboratory through the use of plane straincompression sequences followed by simulated coiling. Tensile samples have been machined from the obtainedspecimens in order to investigate the effect of different variables: recrystallisation or accumulated strain beforetransformation, holding in austenite and coiling temperature on the final mechanical behaviour. Transmissionelectron microscopy observation of the precipitates has been carried out after coiling at different temperatures.It has been shown that when Nb remains in solution in austenite after hot deformation, it can precipitate inferrite, leading to an important strengthening effect which is directly related to the concentration of Nb insolution before transformation and coiling temperature

New World screwworm (Cochliomyia hominivorax) myiasis in feral swine of Uruguay: one Health and transboundary disease implications

Background: Feral swine (Sus scrofa) are highly invasive and threaten animal and human health in the Americas. The screwworm (Cochliomyia hominivorax) is listed by the World Organization for Animal Health as a notifiable infestation because myiasis cases affect livestock, wildlife, and humans in endemic areas, and outbreaks can have major socioeconomic consequences in regions where the screwworm has been eradicated. However, a knowledge gap exists on screwworm infestation of feral swine in South America, where the screwworm is endemic. Here, we report screwworm infestation of feral swine harvested in Artigas Department (Uruguay), where the Republic of Uruguay shares borders with Brazil and Argentina. Methods: Myiasis caused by the larvae of screwworm were identified in feral swine with the support and collaboration of members of a local feral swine hunting club over a 3-year period in the Department of Artigas. Harvested feral swine were examined for the presence of lesions where maggots causing the myiasis could be sampled and processed for taxonomic identification. The sites of myiasis on the body of infested feral swine and geospatial data for each case were recorded. The sex and relative size of each feral swine were also recorded. Temperature and precipitation profiles for the region were obtained from public sources. Results: Myiases caused by screwworms were recorded in 27 of 618 the feral swine harvested. Cases detected in males weighing > 40 kg were associated with wounds that, due to their location, were likely caused by aggressive dominance behavior between adult males. The overall prevalence of screwworm infestation in the harvested feral swine was associated with ambient temperature, but not precipitation. Case numbers peaked in the warmer spring and summer months. Conclusions: This is the first report on myiasis in feral swine caused by screwworm in South America. In contrast to myiasis in cattle, which can reach deep into host tissues, screwworms in feral swine tended to cause superficial infestation. The presence of feral swine in screwworm endemic areas represents a challenge to screwworm management in those areas. Screwworm populations maintained by feral swine may contribute to human cases in rural areas of Uruguay, which highlights the importance of the One Health approach to the study of this invasive host species–ectoparasite interaction

Transversal competences in the Pedagogy degree: diagnosis and state of affairs

[EN] The purpose of this paper is to reflect on the results of an educational innovation project that aims to analyse and organise the transversal competences found in the curricula designed for the Pedagogy degree programme. For this purpose, the situation was assessed by triangulating data from different educational stakeholders. The sample, therefore, was composed of three groups of participants: 1) professional educators who work outside the University of the Basque Country, 2) the Pedagogy degree programme’s teaching staff, and 3) students in the Pedagogy degree programme. Following a thorough contrastive analysis of the information, we concluded that there are transversal competences such as teamwork and oral and written communication that are invariably present in numerous modules. However, there are other transversal competences that are rarely present or receive less attention, as is the case with creativity, digital competence, leadership, and self-directed learning and entrepreneurship. The differences in the amount of attention paid and the weight given to the various competences are a clear call to action: educators must redefine and organise the design of their curricula, along with the assessment of and the work done with transversal competences in the different modules of the Pedagogy degree programme.[ES] La finalidad de este trabajo es reflejar los resultados obtenidos en la realización de un Proyecto de Innovación Educativa que busca analizar y organizar el diseño curricular de las competencias transversales en el Grado de Pedagogía. Para ello, se realiza un diagnóstico de la situación, triangulando las respuestas y los datos de distintos agentes educativos implicados. En consecuencia, la muestra está compuesta por tres grupos de participantes: 1) pedagogos profesionales que trabajan fuera de la propia Universidad del País Vasco, 2) profesorado del grado de pedagogía y 3) alumnado de pedagogía de la propia Facultad. Después de un análisis en profundidad y un contraste de la información, se concluye que hay unas competencias transversales como el trabajo en equipo, la comunicación oral y escrita, que están permanentemente presentes en numerosas asignaturas de grado. Sin embargo, hay otras competencias transversales con una escasa presencia o con una reducida actividad, es el caso de la creatividad, de la competencia digital, el liderazgo y el aprendizaje autónomo o emprendizaje. Estas diferencias en el trabajo y en el peso de unas y otras competencias, suponen un claro aviso y una llamada de atención, para advertir al profesorado universitario de la necesidad de una redefinición u organización del diseño curricular, así como de la evaluación y el trabajo de las competencias transversales en las asignaturas del grado de pedagogía.Eizagirre, A.; Altuna, J.; Pikabea, I.; Marko, JI.; Pérez, V.
