The tripartite interaction between the chromatin remodeler complex RSC, RNA polymerase subunit Rpb5 and prefoldin-like Bud27 is necessary for proper RNA pol II elongation. Indeed lack of Bud27 alters this association and affects transcription elongation. This work investigates the consequences of lack of Bud27 on the chromatin association of RSC and RNA pol II, and on nucleosome positioning. Our results demonstrate that RSC binds chromatin in gene bodies and lack of Bud27 alters this association, mainly around polyA sites. This alteration impacts chromatin organization and leads to the accumulation of RNA pol II molecules around polyA sites, likely due to pausing or arrest. Our data suggest that RSC is necessary to maintain chromatin organization around those sites, and any alteration of this organization results in the widespread use of alternative polyA sites. Finally, we also find a similar molecular phenotype that occurs upon TOR inhibition with rapamycin, which suggests that alternative polyadenylation observed upon TOR inhibition is likely Bud27-dependent.

Las grabaciones tempranas del flamenco representan un eslabón fundamental para la comprensión del desarrollo de este género durante el siglo XX. Estas grabaciones pre-eléctricas surgen en 1897con las primeras impresiones musicales sobre cilindros de cera y continuarán, a través de una presencia constante, a lo largo del inicio de la tecnología fonográfica en España. En el contexto de la música popular en España, durante los primeros años del siglo XX, el flamenco goza de una popularidad que se refleja en un número significante de grabaciones que se conservan al día de hoy. Este acervo sonoro ha recibido poca atención por parte de la comunidad académica y el presente trabajo establece un primer acercamiento a través del enfoque de la interpretación del cante. El presente trabajo – Aspectos estilísticos del cante flamenco temprano: Prácticas vocales en las grabaciones sonoras de 1898 a 1922 – lleva a cabo un análisis de tres prácticas de interpretación que se perciben en las grabaciones tempranas, el vibrato, el timbre y el registro vocal, como un primer acercamiento a definir el estilo del flamenco durante este período. La aproximación metodológica desarrollada se basa en los estudios de las “performance practices” históricas como punto de partida y hace uso de las grabaciones tempranas como fuentes principales de análisis. Asimismo, se ha elaborado un corpus de investigación que reúne las grabaciones sonoras pre-eléctricas de flamenco entre 1897 y 1922, tomando en cuenta como fuente principal el acervo digitalizado de la Biblioteca Nacional de España. A través de la investigación del corpus creado se ha establecido una propuesta de redefinición de aspectos interpretativos del flamenco durante las primeras dos décadas del siglo XX. Asimismo, se ha elaborado un contexto histórico que introduce la presencia e importancia de las grabaciones en el desarrollo del flamenco durante este período. La presente investigación contribuye como una primera aproximación a las grabac, The early recordings of flamenco represent a fundamental link for understanding the development of this genre during the early 20th century. These pre-electric recordings appear in 1897 with the first musical impressions on wax cylinders and will develop consistently throughout the beginning of phonographic technology in Spain.In the context of popular music in Spain, during the first years of the 20th century, flamenco enjoyed a particular popularity that is reflected in a significant number of recordings that survive to this day. This sound heritage has received little attention from the academic community and this dissertation establishes a first approach through the interpretation of cante flamenco. The present thesis – Stylistic aspects of early flamenco singing: Vocal practices in soundrecordings from 1898 to 1922 – carries out an analysis of three interpretation practices that are perceived in early recordings, vibrato, timbre, and vocal register, as a first approach to define the style of early flamenco singing during this period. The methodological approach developed in this research is based on historical performance practices focused on the analysis of early recordings as main sources of study. Likewise, a research data-base has been created which includes the preelectric sound recordings of flamenco between 1897 and 1922, taking into account, as the main source, the digitized collection of the National Library of Spain. Through this investigation, a proposal to redefine interpretive aspects of flamenco during the first two decades of the 20th century has been established. Likewise, a historical context has been elaborated that introduces the importance of recordings in the development of flamenco during this period. This research contributes as a first approximation to early flamenco recordings based on a systematic analysis of the three mentioned vocal practices and presents a series of results that offers an outlining of the vocal style in early flamen

920249 UCM Groups, In industrialized farms, rabbit does undergo intensive production rhythms which overlap lactation and gestation, leading to a high energy mobilization and increasing oxidative stress. Accordingly, we hypothesize that administration of the flavonoid quercetin (QUR) may improve the antioxidant status of young and adult rabbit reproductive females. In this study, the effect of daily oral administration of 300 mg/kg QUR for 8 weeks was assessed on the antioxidant profile of 24 New Zealand × Californian rabbit does, assigned to 4 experimental groups: rearing young (8–16 weeks old) and adult does at the end of their reproductive life (12–14 months old, with at least 3–4 reproductive cycles) treated (YQ and AQ) or not (YC and AC) with QUR, respectively. Plasma glutathione (GSH), as well as serum superoxide dismutase (SOD) and malondialdehyde (MDA) were measured during the experimental period. To assess the health status of the animals, a physical examination was also performed. GSH plasma concentrations were significantly higher in young does at weeks 1 and 4, but not at week 8 of the experiment, irrespectively of QUR administration. An increase in GSH plasma concentration was observed during the 8- week experiment in both AQ and AC groups. Furthermore, QUR administration did not alter either SOD or MDA serum activity and concentration in any group during the experimental period. Physical examination revealed no differences between the experimental groups. In conclusion, under our experimental conditions, QUR did not modify the general clinical or the antioxidant profile of young and adult reproductive rabbit females., Ministerio de Ciencia e Innovación (España), Universidad Complutense de Madrid, Depto. de Producción Animal, Fac. de Veterinaria, TRUE, pub

The recursive inter-network architecture (RINA) introduces great flexibility, scalability and a set of principles that can be applied to quantum networks, yielding a network model based on RINA, which we refer to as RINA-based quantum network. Such approach offers an appropriate solution to address the challenges posed by quantum networks. This paper presents the authors' vision on the potential of RINA-based quantum networks to advance the quantum Internet. First, a model based on packet switching is proposed to carry quantum payloads in local-area scenarios. Then, a RINA-based approach for entanglement-based teleportation is presented for wide-area scenarios. Last, a full RINA-based quantum network model for end-to-end communication is proposed. The proposed model enables the interconnection of packet-switching networks and entanglement-based networks. To the best of the authors' knowledge, this is the first attempt at designing a RINA-based quantum inter-network model, "This work was supported by the grant ONOFRE-3 PID2020-112675RB-C43, funded by MCIN/ AEI /10.13039/501100011033; MINECO (Spain) and the EU NextGenerationEU/PRTR (Call UNICO I+D 5G 2021), 6GSatNet-SeS project, TSI -063000- 2021-8; and Generalitat de Catalunya (Spain) and the EU NextGenerationEU/PRTR (Programa Investigo), 2022 INV-1 00029 - 100029TG2", Peer Reviewed, Postprint (author's final draft)

This work deals with the synthesis of hybrids formed by the natural dye chlorophyll and halloysite for their subsequent application in the textile field. Once the pigments have been synthesized, with 98 % adsorption, they are used for two textile colouring functions, namely printing and dyeing. In both cases, satisfactory and interesting results were obtained. The hybrids were characterized by FTIR, XRD, TGA, SEM-EDX, BET and all the appropriate colour measurements were carried out to obtain the coordinates in CIELAB space and also to know their total solar reflectance (TSR) 45.98 %. In addition, statistical techniques were used with the use of ANOVA to evaluate the results obtained. The dyeing was carried out by exhaustion and its use was compared with the use of nibbled and non-nibbled fabrics. The textiles were tested for fastness and the results are presented in instrumentally obtained grey scale values, achieving in some cases values of 4–5. Thus, the chlorophyll adsorption capacity of halloysite and its stabilisation for subsequent application in printing and dyeing processes on textile substrates has been demonstrated. This process could be scalable at an industrial level.

This article it’s a scientific experiment conducted to extract natural pigments from various plant materials, including chamomile, poppy, common wild madder, holm oak, walnut, and Aleppo pine. The researchers utilized different extraction methods, reagents, and temperatures to obtain colour pigments from these plants. The study aimed to analyze the optical properties and colour characteristics of the extracted pigments. The results indicated that different extraction conditions led to varying colours and intensities. Chamomile extracts showed yellow tones, with significant differences based on extraction methods. Poppy extracts exhibited red and purple shades, influenced by pH levels. Common wild madder samples displayed yellowish to bluish tones, depending on the reagent used. Holm oak extracts showed weak coloration, with slight brownish tinges. Walnut extracts displayed brown tones, while Aleppo pine extracts exhibited brown shades with differences in intensity based on pH levels. Chicory extracts showed green to purple tones, varying with different reagents. The study involved a thorough analysis of the colorimetric properties, including clarity, hue, and saturation, of the extracted pigments under different conditions. Statistical analyses were performed to compare the effects of reagents, temperatures, and plant sources on the colour properties. The findings demonstrated significant differences in colour attributes based on these factors. The importance of the use of natural colorants is also recalled., emphasizing their eco-friendly nature and reduced environmental impact compared to synthetic colorants. The study's results contribute valuable information on the extraction and characterization of natural pigments from diverse plant sources, providing insights for potential applications in textiles and other industries.

Health systems are the set of political, economic and institutional relationships responsible for the conduct of processes related to the health of the population, which are expressed in organizations, standards and services, which aim to achieve results consistent with the conception of prevalent health in society. According to the World Health Organization (WHO), the functioning of a health system mainly includes: Stewardship, provision of health services, financing and human resources. With the definition of health proposed and considered by the state, of complete physical, mental and social well-being, various epidemiological perspectives on population health are proposed. Which allows us to address social aspects of health such as the social determinants of the inhabitants. Determination in health is the process because the various forms of illness or death of the population occur. In conclusion, the public health system is the result of all the organizations, institutions and resources whose main objective is to offer excellent care to the population, which are provided at no cost, trying to eliminate walls of access to the services that provided by the Ministry of Health, in order to go to any of them regardless of the economic or health condition of the patient, and if the patient is not affiliated with any type of insurance, they can be guaranteed universal access for Ecuadorians to free health, What is our right as provided in the Political Constitution of Ecuador?., Los sistemas de salud son el conjunto de relaciones políticas, económicas e institucionales responsables por la conducción de los procesos relativos a la salud de la población, que se expresan en organizaciones, normas y servicios, que tienen como objetivo alcanzar resultados consistentes con la concepción de salud prevalente en la sociedad. Según la Organización Mundial de la Salud (OMS), el funcionamiento de un sistema de salud contempla principalmente: La rectoría, provisión de los servicios de salud, financiamiento y recursos humanos. Con la definición de salud propuesta y considerada por el estado, de completo bienestar físico, mental y social, se plantean diversas perspectivas epidemiológicas sobre la salud poblacional. La cual nos permite abordar aspectos sociales de la salud como son los determinantes sociales de los habitantes. La determinación en salud es el proceso porque se producen las diversas formas de enfermar o morir de la población. En conclusión el sistema de salud pública es el resultado de todas las organizaciones, instituciones y recursos que tienen como su principal objetivo ofrecer excelentes atención a la población, las mismas que son brindadas sin costo alguno, tratando de eliminar murallas de acceso a los servicios que brinda el ministerio de salud, para así acudir a cualquiera de ellos sin importar la condición económica o de salud del paciente, no estando este afiliado a ningún tipo de seguro, se les pueda garantizar el acceso universal de los ecuatorianos a la salud gratuita, la cual es nuestro derecho como lo dispone la Constitución Política del Ecuador.

The sustainability of sheep production systems may be at risk and must be evaluated in order to identify actions to improve their performance. Therefore, the objective of this research was to evaluate the sustainability of sheep production units in the highlands area of the state of Michoacán, Mexico. The method of sustainability indicators of agricultural holdings was used, through the scales: agroecological, socio-territorial and economic. 40 indicators were evaluated through a semi-structured survey in 108 production units. The indicators of each sheep production unit were concentrated in a database and scores were obtained according to the method guide. In order to group sheep production units with similar characteristics, a multivariate cluster analysis was carried out using the hierarchical method. Significant differences (p ≤ 0.05) were found in the three scales evaluated with: 42.3; 47.7 and 50.0% sustainability units respectively. The main limitation of sustainability was the agroecological scale, in the space organization component. Four clusters of sheep production units with different characteristics were obtained. The sheep production units in the area have not reached a state of acceptable sustainability. The limited land area puts its permanence at risk. These production units manage to generate economic resources and support family self-sufficiency, which has allowed them to remain over time, due to the diversity of the agricultural species they manage., La sostenibilidad de los sistemas de producción ovina puede estar en riesgo y debe ser evaluada con el fin de identificar acciones para mejorar su desempeño. Por lo tanto, el objetivo de la presente investigación fue evaluar la sostenibilidad de las unidades de producción ovina en la zona del Altiplano del estado de Michoacán, México. Se utilizó el método de Indicadores de sostenibilidad de las explotaciones agropecuarias, a través de las escalas: agroecológica, socio-territorial y económica. Se evaluaron 40 indicadores, mediante una encuesta semiestructurada en 108 unidades de producción. Los indicadores de cada unidad de producción ovina se concentraron en una base de datos y se obtuvieron los puntajes de acuerdo a la guía del método. Con el propósito de agrupar las unidades de producción ovinas con características similares, se realizó un análisis multivariado de conglomerados utilizando el método jerárquico. Se encontraron diferencias significativas (p ≤ 0,05) en las tres escalas evaluadas con: 42,3; 47,7 y 50,0% unidades de sostenibilidad respectivamente. La principal limitante de la sostenibilidad fue la escala agroecológica, en el componente de organización del espacio. Se obtuvieron cuatro conglomerados de las unidades de producción ovinas con diferentes características. Las unidades de producción ovina de la zona no han alcanzado un estado de sostenibilidad aceptable. La limitada superficie de terreno pone en riesgo su permanencia. Estas unidades de producción logran generar recursos económicos y apoyan el autoabastecimiento familiar, lo que les ha permitido permanecer a través del tiempo, debido a la diversidad de las especies agropecuarias que manejan.

In this article, I explore the translation of male homoeroticism through dubbing, starting from the premise that contemporary telefiction incorporates various dimensions of sexuality into its narratives and character development. The study case is Looking, a dramady series produced by HBO and broadcast initially from 2014 to 2016. HBO's Looking serves as a key example to explore how the interplay between visual and linguistic semiotic resources is crucial for televisual storytelling. The aim of the study is twofold: to identify the semiotic interactions between visual modes and the linguistic code in scenes involving sex talk or intimacy between male characters in Looking; and to contrast how the translations for dubbing into neutral Spanish (for Latin America) and Peninsular Spanish contributed to or transformed the representation of intermale desire. The findings are analyzed within the context of gender and queer translation studies, as well as affect theory. A general argument derived from the study is that neutrality and taboo carry prescriptive components that need to be challenged to understand how sexual imaginaries are currently circulating through media and translation., En el presente artículo se analiza la traducción del homoerotismo mediante el doblaje. El estudio parte del supuesto de que la teleficción contemporánea integra distintas dimensiones de la sexualidad como parte de la narrativa y la construcción de los personajes. El caso de estudio es Looking, una serie de drama y comedia producida por HBO y transmitida originalmente entre 2014 y 2016. Esta serie de televisión es un caso relevante para identificar cómo la interacción entre recursos semióticos visuales y lingüísticos son fundamentales para sostener el relato. El objetivo del estudio es doble: identificar las interacciones semióticas entre los modos visuales y el código lingüístico en escenas que involucran conversaciones sexuales o intimidad entre personajes masculinos en Looking; y contrastar cómo las traducciones para el doblaje al español neutro (para América Latina) y al español peninsular contribuyeron o transformaron la representación del deseo entre hombres. Los hallazgos se analizan en el contexto de los estudios de traducción cuir y de género, así como en la teoría de los afectos. Un argumento general derivado del estudio es que la neutralidad y el tabú conllevan componentes prescriptivos que deben cuestionarse para comprender cómo circulan actualmente los imaginarios sexuales mediante los medios y la traducción.

Los resultados muestran una adsorción exitosa del pigmento en todos los experimentos, con porcentajes de adsorción superiores al 97%. Se evalúa el color de los híbridos y se analiza la reflectancia solar total, destacando la importancia de estos en aplicaciones como revestimientos y textiles impresos. Se utiliza espectroscopia de infrarrojo y difracción de rayos X para estudiar las propiedades estructurales de los híbridos. Para futuros trabajos se pretende poder aplicar a escala industrial los híbridos obtenidos en coloración de textiles y polimeros plásticos.

Los eventos de alta energía (tempestades/tsunamis/inundaciones) quedan normalmente registrados como niveles de sedimentos más gruesos y mal seleccionados. Este trabajo busca identificar posibles eventos de alta energía en el registro sedimentario litoral del Holoceno de Guardamar del Segura en las proximidades del yacimiento fenicio de Cabezo Pequeño del Estaño del siglo VIII a.C. La granulometría por difracción laser del sondeo de 5,50 m de profundidad, muestra predominio de limo fino. A la profundidad de 3,80 m el sondeo contiene un nivel de sedimentos bimodales (arena fina y limo grueso) muy mal seleccionados. La asimetría positiva de la moda de arenas indica que podrían ser sedimentos dunares transportadas por un desbordamiento costero de olas de tempestad o tsunami hacia el antiguo entrante marino, hoy soterrado. Sin embargo, el resultado del análisis FTIR (Reflectancia total atenuada de Espectroscopía Infrarroja) indica alrededor de 4,00 m de profundidad un predominio de carbonatos, correspondiente a dolomías ricas en hierro, de procedencia continental, el cual puede deberse a un evento de alta energía que llegó desde el interior. Al no ser posible la datación por falta de preservación de material datable, se ha considerado una tasa de sedimentación ya descrita en la bibliografía de 1,9 mm/año, con la cual se deduce que el evento de inundación de alta energía ocurrió alrededor de hace 2000 años., High-energy events (storms/tsunamis/floods) are recorded as thicker, poorly sorted sediment levels. This work seeks to identify possible high-energy events in the Holocene sedimentary record of Guardamar del Segura in the vicinity of the Phoenician site of Cabezo Pequeño del Estaño from the 8th century BC. The laser diffraction granulometry of the 5.50 m deep borehole shows a predominance of fine silt. At a depth of 3.80 m, the borehole contains a level of bimodal sediments (fine sand and coarse silt) that are very poorly selected. The positive asymmetry of the sand pattern indicates that they could be dune sediments transported by a coastal overflow by storm waves or tsunamis towards the ancient marine inlet, now buried. However, the result of the FTIR analysis indicates around 4.00 m depth a predominance of iron-rich dolomites, from inland, thus could indicate the high energy event that arrived from the interior. Since dating is not possible due to lack of preservation of datable material, a sedimentation rate already described in the bibliography of 1.9 mm/year has been considered, from which it is deduced that the high-energy event occurred around 2000 years ago.

Este estudio de corte etnográfico, apartir de informantes clave, se develan que las percepciones de los pobladores en términos de beneficio social, económico, y con menos impactos a los ecosistemas naturales en la región de San Jacinto, en Arriaga Chiapas, por la instalación del parque eólico, resultaron desalentadoras, frustrantes e impotentes ante la simulación de las promesas de mejora económica y social para todos los habitantes de la región por parte de la empresa Grupo Dragón. El 98 % de los habitantes percibió que la instalación del desarrollo eólico no mejoró las condiciones de vida, por el contrario, causó graves daños al ambiente, como la pérdida de la cobertura vegetal, descenso y cambios en el sabor del agua de los pozos, daños a la salud, migrañas y dolores de oído ocasionados por los ruidos permanentes de los aerogeneradores, además de retrocesos sociales y económicos en la región.

The increase in life expectancy among people with intellectual and/or developmental disabilities (IDD) implies an aging process, which challenges entities that manage special employment centers (CEE). The use of the PROLAB76 tool can help to detect this deterioration and activate personalized support plans.The study, of exploratory descriptive quantitative nature, was conducted with the participation of 49 workers with IDD over 45 years of age or those younger showing signs of aging, applying the PROLAB76 tool.Results reveal a low level of labor deterioration in SECs of Afanias, although some dimensions stand out with profiles of moderate and intense support such as cognitive functioning, emphasizing the importance of individualized support approaches in combination with general measures within the entity, due to similar outcomes in many of the evaluated participants.This study provides evidence about the usefulness of PROLAB76, as it allows for the detection and specific identification of the signs of labor deterioration showing greater frequency and intensity, enabling the development of individualized support plans., El aumento de la esperanza de vida entre personas con discapacidad intelectual y/o del desarrollo (DID) implica un proceso de envejecimiento, que desafía a entidades que gestionan centros especiales de empleo (CEE). La utilización de la herramienta PROLAB76 puede ayudar a detectar este deterioro y activar planes de apoyos personalizados. En el estudio, de carácter cuantitativo exploratorio descriptivo, participaron 49 personas trabajadoras con DID mayores de 45 años o aquellas menores con señales de envejecimiento, aplicando la herramienta PROLAB76. Los resultados revelan un bajo deterioro laboral en centros especiales de empleo de Afanias, aunque algunas dimensiones destacan con perfiles de apoyo moderado e in-tenso, como es el caso del funcionamiento cognitivo, subrayando la importancia de enfoques de apoyo individualizados en combinación con medidas generales en la entidad, debido a resultados similares en muchos de las personas participantes evaluadas. En este estudio se proporcionan evidencias acerca de la utilidad de PROLAB76, ya que permite detectar e identificar específicamente cuáles son los signos de deterioro laboral que muestran mayor frecuencia e intensidad, permitiendo elaborar planes de apoyo individualizado.

The general objective of the research was to determine whether prenatal care given during the Covid-19 pandemic was related to anemia of pregnancy in a public hospital in Lima, 2021. A quantitative, non-experimental, descriptive-correlational-retrospective, hypothetical-deductive methodology was used; a documentary analysis of the perinatal medical records of pregnant women was carried out and a technical data collection sheet was applied, taking as a sample 192 medical records of pregnant women who attended prenatal care during the period of 2021 and presented with anemia of pregnancy. The results showed a significance level of 0.023 in the X2 statistical test for the variable number of prenatal care and gestational anemia, demonstrating that there is a significant relationship between these two variables., El objetivo general de la investigación fue determinar si las atenciones prenatales que se dio durante la pandemia por Covid-19 tuvieron relación con anemia del embarazo en un hospital público de Lima, 2021.

Hallando en los resultados un nivel de significancia de 0.023 en la prueba estadística X2 de la variable número de atenciones prenatales y anemia de la gestación, demostrando que existe una relación significativa entre estas dos variables.

The aim of this study is to inventory and study ethnobotanical knowledge of edible plants in the Valencian Community (Spain). In respect to culinary uses, 92 species of plant were reported to be edible, finding the following uses: 58 raw, 52 cooked, 16 fried, 7 dried, 21 in liquors and beverages, 25 in dessert and sweets, 11 as seasoning, 17 in pickles, and 10 to curdle milk. We prepared a database that includes genus, family, scientific, and vernacular names in Spanish and Catalan for each plant. We also created a classification of nine edible uses and plant parts used, being Asteraceae (n = 18), Brassicaceae (n = 7), Chenopodiaceae (n = 6), and Rosaceae (n = 6) the families most characterized for gastronomic purposes. The species with the most elevated cultural importance (CI) values were Foeniculum vulgare (CI = 1.389), Cynara scolymus (CI = 1.374), Papaver rhoeas (CI = 1.211), Beta vulgaris (CI = 1.167), and Juglans regia (CI = 1.155). The most used parts were the leaves (71), flowers (25), and branches (19), while the least used were roots (9) and seeds (8). Traditional knowledge of these plants helps to preserve traditional cuisine, promote the local economy and, in several species, encourage their cultivation.

Currently, there is a growing interest in the study of fertility because fertility-related problems affect up to 15% of the world’s population. The aim of this study was to determine the influence of the Mediterranean diet on seminal quality in men of reproductive age. For this purpose, a systematic review of the literature was carried out following the PRISMA method. Electronic searches were carried out in the international databases PubMed, Scopus, the Cochrane Library, and Web of Science. In total, 10 articles with 2032 men were included. As inclusion criteria, articles published between 2012 and 2022 were selected, including those that included men aged between 18 and 55 years. Nutritional status was assessed through weight, height, and BMI. Dietary habits were evaluated through different indexes and food frequency questionnaires, and finally, semen quality was evaluated by measuring sperm concentration and motility (progressive and non-progressive). In six (60%) of the included articles, a positive relationship between adherence to the Mediterranean diet and semen quality was demonstrated; in two (20%) of the articles, no association was found; and finally, in two (20%) of the included articles, the relationship between dietary patterns typical of DM and semen quality was evaluated. Dietary habits influence semen quality. Adherence to the Mediterranean diet can improve male reproductive health, as it is a diet with antioxidant and anti-inflammatory effects. This is the first systematic review about the influence of the Mediterranean diet on semen quality, and the results are positive. These findings may allow us to provide better advice to our patients and to establish interventions with the aim of improving the results of assisted reproduction techniques.

In the present research, we studied gaming and students' cognitive development using a literature review and analytical methods in the context of a descriptive non-experimental research. Through a comprehensive review of the existing literature, we sought to clarify the meaning and importance of games in students' cognitive development. This analytical approach allows for a detailed study of different dimensions of play, examining how game activities affect basic cognitive skills such as problem solving, critical thinking, and creativity. A literature review approach provides a powerful framework for examining previous research and synthesizing key findings to provide a comprehensive picture of the role of play in students' cognitive development, yielding the following results: the characteristic relationship between play and cognitive development is highlighted, it is observed that play positively impacts various cognitive dimensions, activating memory, stimulating attention and concentration, fostering creativity and imagination, and providing opportunities for the development of higher cognitive skills, concluding that lack of pedagogical awareness and resource constraints are significant obstacles to the full utilization of games as an educational tool, academic pressure and disciplinary prioritization also negatively affect the integration of recreational activities in educational institutions. The need to address these issues to ensure that students can take full advantage of play for their cognitive development is highlighted., En la presente investigación se estudió el juego y el desarrollo cognitivo de los estudiantes utilizando una revisión de la literatura y métodos analíticos en el contexto de una investigación descriptiva no experimental. A través de una revisión exhaustiva de la literatura existente, buscamos esclarecer el significado y la importancia de los juegos en el desarrollo cognitivo de los estudiantes. Este enfoque analítico permite un estudio detallado de diferentes dimensiones del juego, examinando cómo las actividades de juego afectan las habilidades cognitivas básicas como la resolución de problemas, el pensamiento crítico y la creatividad. Un enfoque de revisión de la literatura proporciona un marco poderoso para examinar investigaciones previas y sintetizar hallazgos clave para proporcionar una imagen integral del papel de los juegos en el desarrollo cognitivo de los estudiantes, obteniendo así los siguientes resultados: se destaca la relación característica entre el juego y el desarrollo cognitivo, se observa que el juego incide positivamente en diversas dimensiones cognitivas, activando la memoria, estimulando la atención y concentración, fomentando la creatividad y la imaginación, y proporcionando oportunidades para el desarrollo de habilidades cognitivas superiores, concluyendo que la falta de conciencia pedagógica y las limitaciones de recursos son obstáculos significativos para el pleno aprovechamiento de los juegos como herramienta educativa, la presión académica y la priorización disciplinaria también afectan negativamente la integración de actividades recreativas en las instituciones educativas. Se destaca la necesidad de abordar estas cuestiones para garantizar que los estudiantes puedan aprovechar al máximo el juego para su desarrollo cognitivo.

Immune defenses are crucial for survival but costly to develop and maintain. Increased immune investment is therefore hypothesized to trade-off with other life-history traits. Here, we examined innate and adaptive immune responses to environmental heterogeneity in wild Antarctic fur seals. In a fully crossed, repeated measures design, we sampled 100 pups and their mothers from colonies of contrasting density during seasons of contrasting food availability. Biometric and cortisol data as well as blood for the analysis of 13 immune and oxidative status markers were collected at two key life-history stages. We show that immune responses of pups are more responsive than adults to variation in food availability, but not population density, and are modulated by cortisol and condition. Immune investment is associated with different oxidative status markers in pups and mothers. Our results suggest that early life stages show greater sensitivity to extrinsic and intrinsic effectors, and that immunity may be a strong target for natural selection even in low-pathogen environments such as Antarctica.

Satellites have the opportunity to overcome the range limit of quantum communications based on fiber networks. This paper presents a method for performance evaluation of QKD based on satellites, exemplified with a case study that considers small satellites (CubeSats) in low Earth orbits (LEO), to illustrate a flexible configuration of the quantum range extender use case. To the best of the authors’ knowledge, this is the first time that a system evaluation derived from orbital propagation data is conducted while also considering QKD with a finite key statistics approach. This evaluation aims to match with the shortness and variability of visibility intervals typical of LEO orbits. The results confirm the feasibility of proposed case study and show the impact of relevant systems and orbital parameters in the key generation performance, such as system characteristics, uplink or downlink configuration, satellite altitude and orbital inclination. The estimated performance is then scaled to a year along with some sensitivity scenarios.

The effects of global warming are numerous and recent studies reveal that they can affect the timing of pollination. Temperature is the meteorological variable that presents a clearer relationship with the start of the pollination season of most of the observed airborne pollen taxa. In Catalonia, in the last fifty years, the average annual air temperature has increased by +0.23 ¿C/decade, and the local warming has been slightly higher than the one on a global scale. Projections point to an increase in temperature in the coming decades, which would be more marked towards the middle of the century. To analyse the effect of the increase in temperature due to global warming on the starting date of pollen season in Barcelona, a forecasting model has been applied to a set of projected future temperatures estimated by the European RESCCUE project. This model, largely used in the literature, is based on determining the thermal needs of the plant for the pollen season to begin. The model calibration to obtain the initial parameters has been made by using 20 years of pollen data (2000–2019), and the model effectiveness has subsequently been tested through an internal evaluation over the period of the calibration and an external evaluation on 4 years not included in the calibration (2020–2023). The mean bias error in the internal calibration ranged between –0.4 and –0.6 days, and between +0.5 and –8.3 in the external one, depending on the taxon. The results of the application of the model to the temperature projections over the 21st century point to a progressive advancement in the pollination dates of several pollen types abundant in the city, allergenic most of them. These advances ranged, at the end of the century, between 15 and 27 days, depending on the climate model, for the scenario of the highest concentrations (RCP8.5) and between 7 and 12 days for the emissions stabilization scenario (RCP4.5)., Peer Reviewed, Postprint (published version)

Female reproductive success is mainly determined by age and ovarian reserve (OR). Recent studies highlight the influence of modifiable factors such as dietary habits and nutritional status on OR. In this regard, the Mediterranean Diet (MD) is postulated as a standard of healthy eating. Therefore, the objective of this paper was to analyze the influence of adherence to DM and nutritional status on the OR of infertile women. METHODS // A descriptive cross-sectional study was carried out, lasting one year, between February 2022 and February 2023, in a sample of forty-five female patients who attended the Gynaecology-Esterility consultation at the Marina Salud Hospital in Denia (Spain) due to genital desire older than one year. An exploratory descriptive analysis based on univariate statistics was performed. RESULTS // The mean age of the sample (n=45) was 31.84 (±3.99) years, with an average BMI of 26.27 (±6.08) kg/m2, with 44.4% (n=20) having excess body weight. The RO was measured based on AMH, with an average value of 2.32 (±1.59) ng/ml and RFA, with an average of 19.80 (±14.13) antral follicles. A statistically significant association was found between low adherence to DM and lower anti-Müllerian hormone (AMH; p=0.025) levels. In addition, an association was found between low consumption of vegetables (p=0.044), excessive consumption of red meat (p=0.027) and carbonated beverages (p=0.015) with insufficient AMH levels, indicative of low OR. Low fruit consumption was also found to be associated with low oestradiol levels (p=0.045). Statistically significant associations were also found reflecting the influence of nutritional status on OR. CONCLUSIONS // One of the main factors conditioning the success of ART (assisted reproductive technology) is the woman’s OR. The most widely used parameter to assess OR is AMH. Lifestyle and diet are modifiable factors that can influence OR.

Genotoxicity of PAH-contaminated soils can eventually increase after bioremediation due to the formation and accumulation of polar transformation products, mainly oxygenated PAHs (oxy-PAHs). Biodegradation of oxy-PAHs has been described in soils, but information on the microorganisms and mechanisms involved is still scarce. Benz(a)anthracene-7,12-dione (BaAQ), a transformation product from benz(a)anthracene frequently detected in soils, presents higher genotoxic potential than its parent PAH. Here, using sand-in-liquid microcosms we identified a specialized BaAQ-degrading subpopulation in a PAH-contaminated soil. A BaAQ-degrading microbial consortium was obtained by enrichment in sand-in-liquid cultures with BaAQ as sole carbon source, and its metagenomic analysis identified members of Sphingobium, Stenotrophomonas, Pusillimonas, Olivibacter, Pseudomonas, Achromobacter, and Hyphomicrobiales as major components. The integration of data from metabolomic and metagenomic functional gene analyses of the consortium revealed that the BaAQ metabolic pathway was initiated by Baeyer-Villiger monooxygenases (BVMOs). The presence of plasmid pANTQ-1 in the metagenomic sequences, identified in a previous multi-omic characterization of a 9,10-anthraquinone-degrading isolate recovered from the same soil, suggested the occurrence of a horizontal gene transfer event. Further metagenomic analysis of the BaAQ-degrading consortium also provided insights into the potential roles and interactions within the consortium members. Several potential auxotrophies were detected, indicating that relevant nutritional interdependencies and syntrophic associations were taking place within the community members, not only to provide suitable carbon and energy sources, but also to supply essential nutrients and cofactors. Our work confirms the essential role that BVMO may play as a detoxification mechanism to mitigate the risk posed by oxy-PAH formation during bioremediation of contaminated soils.

Long-period transiting exoplanets bridge the gap between the bulk of transit- and Doppler-based exoplanet discoveries, providing key insights into the formation and evolution of planetary systems. The wider separation between these planets and their host stars results in the exoplanets typically experiencing less radiation from their host stars; hence, they should maintain more of their original atmospheres, which can be probed during transit via transmission spectroscopy. Although the known population of long-period transiting exoplanets is relatively sparse, surveys performed by the Transiting Exoplanet Survey Satellite (TESS) and the Next Generation Transit Survey (NGTS) are now discovering new exoplanets to fill in this crucial region of the exoplanetary parameter space. This study presents the detection and characterisation of NGTS-30 b/TOI-4862 b, a new long-period transiting exoplanet detected by following up on a single-transit candidate found in the TESS mission. Through monitoring using a combination of photometric instruments (TESS, NGTS, and EulerCam) and spectroscopic instruments (CORALIE, FEROS, HARPS, and PFS), NGTS-30 b/TOI-4862 b was found to be a long-period (P = 98.29838 day) Jupiter-sized (0.928 RJ; 0.960 MJ) planet transiting a 1.1 Gyr old G-type star. With a moderate eccentricity of 0.294, its equilibrium temperature could be expected to vary from 274 K to 500 K over the course of its orbit. Through interior modelling, NGTS-30 b/TOI-4862 b was found to have a heavy element mass fraction of 0.23 and a heavy element enrichment (Zp/Z_star) of 20, making it metal-enriched compared to its host star. NGTS-30 b/TOI-4862 b is one of the youngest well-characterised long-period exoplanets found to date and will therefore be important in the quest to understanding the formation and evolution of exoplanets across the full range of orbital separations and ages., Comment: 18 pages, 14 figures, accepted for publication in A&A

We report the discovery and characterization of three giant exoplanets orbiting solar-analog stars, detected by the \tess space mission and confirmed through ground-based photometry and radial velocity (RV) measurements taken at La Silla observatory with \textit{FEROS}. TOI-2373\,b is a warm Jupiter orbiting its host star every $\sim$ 13.3 days, and is one of the two most massive known exoplanet with a precisely determined mass and radius around a star similar to the Sun, with an estimated mass of m$_p$ = $9.3^{+0.2}_{-0.2}\,M_{\mathrm{jup}}$, and a radius of $r_p$ = $0.93^{+0.2}_{-0.2}\,R_{\mathrm{jup}}$. With a mean density of $\rho = 14.4^{+0.9}_{-1.0}\,\mathrm{g\,cm}^{-3}$, TOI-2373\,b is among the densest planets discovered so far. TOI-2416\,b orbits its host star on a moderately eccentric orbit with a period of $\sim$ 8.3 days and an eccentricity of $e$ = $0.32^{+0.02}_{-0.02}$. TOI-2416\,b is more massive than Jupiter with $m_p$ = 3.0$^{+0.10}_{-0.09}\,M_{\mathrm{jup}}$, however is significantly smaller with a radius of $r_p$ = $0.88^{+0.02}_{-0.02},R_{\mathrm{jup}}$, leading to a high mean density of $\rho = 5.4^{+0.3}_{-0.3}\,\mathrm{g\,cm}^{-3}$. TOI-2524\,b is a warm Jupiter near the hot Jupiter transition region, orbiting its star every $\sim$ 7.2 days on a circular orbit. It is less massive than Jupiter with a mass of $m_p$ = $0.64^{+0.04}_{-0.04}\,M_{\mathrm{jup}}$, and is consistent with an inflated radius of $r_p$ = $1.00^{+0.02}_{-0.03}\,R_{\mathrm{jup}}$, leading to a low mean density of $\rho = 0.79^{+0.08}_{-0.08}\,\mathrm{g\,cm}^{-3}$. The newly discovered exoplanets TOI-2373\,b, TOI-2416\,b, and TOI-2524\,b have estimated equilibrium temperatures of $860^{+10}_{-10}$ K, $1080^{+10}_{-10}$ K, and $1100^{+20}_{-20}$ K, respectively, placing them in the sparsely populated transition zone between hot and warm Jupiters.

The countermovement jump, the V-cut test, the muscle thickness and the adjacent subcutaneous fat thickness of the gastrocnemius medialis and rectus femoris are important physiological indicators for success in basketball. The aims of this study were to evaluate between-age-category and between-gender differences in these indicators and examine the relationships between physical tests and ultrasound measurements. The measurements were recorded in a sample of 131 elite basketball players (66 males) who played in three age-categories (U14, U16, or U18). We performed two-way analysis of covariance tests and age-adjusted partial correlation analyses. U16 and U18 males showed better performance in the countermovement jump and V-cut tests and lower adjacent subcutaneous fat thickness of the gastrocnemius medialis and rectus femoris compared to the U14 males (p≤.001) and to age-category equivalent female players (p≤.001). Comparisons between the age categories in females did not show significant differences in any of the study variables. Adjacent subcutaneous fat thickness of the gastrocnemius medialis explained 22.3% of the variation for the countermovement jump result and 12.9% of the variation for the V-cut result in males (p<.01). This study is the first to show the association and predictive role of subcutaneous fat thickness measured by ultrasound in physical performance of male and female elite youth basketball players.

This article is placed in the line of research on the teaching of poetry. Based on a permanent education experience conceived as a Teachers as Readers Group, this qualitative study is aimed at observing the possible incidence of this formative instance in the evaluation that secondary education teachers make of poetic works, as well as in the didactic proposals they develop about them. This is done through the analysis of the self-confrontation writings of seven teachers who reflect on their own comments on texts and their didactic proposals about a poetry picturebook, as well as data from interviews. The results report a positive incidence in aspects such as the consideration of the reader or the importance of socialization between readers as a pivotal part of literary education. Finally, this paper discusses the need to move towards the construction of professional learning communities that open a path to development for the constraints that affect teachers in the field of teaching poetry in the classroom., El presente artículo se sitúa en la línea de investigación sobre enseñanza de la poesía. A partir de una experiencia de formación continua concebida como un Teachers as Readers Group, se articula un estudio cualitativo cuyo objetivo es observar la posible incidencia de esta instancia formativa en la valoración que docentes de educación secundaria hacen de obras poéticas, así como en las propuestas didácticas que elaboran sobre estas. Para ello se analizan los escritos de autoconfrontación de siete docentes que reflexionan sobre sus propios comentarios de texto y propuestas didácticas acerca de un álbum lírico, lo que se complementa con datos provenientes de entrevistas. Los resultados informan una incidencia positiva en aspectos como la consideración del sujeto lector o la importancia de la socialización entre lectores como parte fundamental de la educación literaria. Finalmente, se discute la necesidad de avanzar hacia la construcción de comunidades de aprendizaje profesionales, que pueden abrir una vía de desarrollo para las tensiones que afectan al profesorado en el ámbito de la enseñanza de poesía en las aulas.

Objective. This research aims to modify and validate a scale for assessing students’ perceptions of pedagogical practices employed in classrooms to foster 21st-century skills. Methods. The WVDE-CIS-28 scale, originally designed for teachers, was adapted and administered through a survey to a sample of 3432 high school students from 26 schools in the Biobío region, Chile. An exploratory factor analysis (EFA) and a confirmatory factor analysis (CFA) were conducted to determine the number of underlying dimensions and verify whether the proposed theoretical model with 8 dimensions showed a significant statistical adjustment. Results. The validation analyzes of the scale confirmed the factorial structure of the original instrument, which comprised the dimensions of critical thinking, collaboration, communication, creativity and innovation, self-direction, global relations, local relations, and the use of learning technologies.

En Guarayos, como en gran parte de las tierras bajas bolivianas, el acaparamiento y la concentración de la tierra es la base en que se asienta el poder económico y político; de ahí que la estructura de tenencia de la tierra sea fundamental en la configuración de las relaciones sociales, dado que el fundo conforma un espacio económico, social y cultural. Objetivo de este artículo es un análisis del acceso legal de los guarayos a la tierra, a través de los llamados sindicatos agrarios o comunidades campesinas, en aplicación de la reforma agraria aprobada por el Gobierno del Movimiento Nacionalista Revolucionario en 1953.

El 28 y 29 de septiembre de 2022, el Taller de Estudios e Investigaciones Andi-no-Amazónicos y el Instituto Francés de Estudios Andinos organizaron el simposio Los Escenarios del Poder Local en América Latina, Siglos XIX-XX. Objetivo de la reunión fue analizar diversas problemáticas en torno al ámbito local, como fueron, entre otras, el acceso y la explotación económica de los recursos naturales, los actores sociales involucrados, y la adaptación y/o resistencia de organizaciones y liderazgos tradicionales indígenas al ordenamiento liberal. Los trabajos presentados dilucidaron varios aspectos relativos al poder local en Chile, El Salvador, Ecuador, Brasil, Perú y Bolivia. Todos los estudios propiciaron debates interesantes; no obstante, atendiendo a las normas editoriales relativas a la publicación de dosieres en el Boletín Americanista, consideramos conveniente proponer a la revista cuatro de los trabajos presentados, cuyo de-nominador común era el abordaje del poder local en Bolivia desde diversas mi-radas en torno a la importancia de las instituciones locales en la construcción del Estado durante la temprana república, las conflictivas relaciones existentes en relación con la ocupación y el control de territorio y población en el Chaco en la segunda mitad del siglo XIX, las estrategias utilizadas por las comunidades chiriguanas en ese mismo período para preservar tierras y liderazgos ante el avance del frente colonizador y, por último, el acceso legal de los guarayos a la tierra en aplicación de la reforma agraria aprobada por el Gobierno boliviano en 1953.

Background: Small-scale livestock systems provide quality food for a growing demand of animal protein worldwide. Although these systems help to improve rural living standards and reduce the environmental footprint new feeding strategies should be tested to improve animal productivity. Sunflower -which is native to México- and chickpea -also common in the study area- may be used as feed alternatives for dairy goats. Objective: To evaluate the effect of substituting corn straw with sunflower-chickpea hay on yield and nutrient composition of goat milk. Methods: In this participatory study, a total of 28 multiparous Saanen dairy goats were randomly assigned to two treatments (14 goats each) during a 30-day experiment in a small farm. Two weeks prior to the experiment all goats received an adaptation diet. One treatment (MZST) received a conventional diet of lucerne hay (200 g/goat/day) and concentrate (400 g/goat/day), plus 600 g/goat/day (50% of the ration) of corn straw. The second treatment (SFCPT) contained the same lucerne and concentrate content with 600 g/goat/day of sunflower-chickpea hay. Milk yield and composition, and live weight and body condition of the goats were recorded for each treatment. Results: SFCPT significantly increased milk yield, protein, and solids content, but no difference was observed in milk fat. Conclusion: Dietary supplementation of goats with sunflower and chickpea hay increases milk production, protein, and total solids content compared with corn hay., Antecedentes: Os sistemas de produção animal em pequena escala têm um papel importante no fornecimento de alimentos de qualidade para atender uma demanda mundial crescente desses produtos, para melhorar a subsistência rural e para reduzir a pegada ambiental. Há uma necessidade, porem, de aumentar a produtividade através de estratégias de alimentação melhoradas. O girassol é nativo do México e o grão-de-bico é uma cultura comum na área de estudo que podem representar uma alternativa na alimentação de caprinos leiteiros. Objectivo: Avaliar através de investigação participativa na exploração o efeito da substituição da palha de milho tradicionalmente utilizada na alimentação de cabras leiteiras por uma forragem alternativa adaptada à região, mas não utilizada até o momento, em termos de rendimento, composição química de leite fresco de cabras. Métodos: Vinte e oito cabras leiteiras Saanen multipares foram designadas aleatoriamente a dois tratamentos (14 cabras/tratamento), em um experimento de 30 dias numa fazenda de pequena escala. Duas semanas antes do experimento, todos os caprinos receberam uma dieta de adaptação. Um tratamento (MZST) recebeu a dieta convencional de feno de alfalfa (200 g/caprino/dia) e concentrado (400 g/caprino/dia) mais 600 g/caprino/dia (50% da ração) de palha de milho. O segundo tratamento (SFCPT) tinha a mesma proporção de alfalfa e concentrado, mas com 600 g/caprino/dia de feno de girassol e grão-de-bico. O rendimento e composição do leite, o peso vivo e a condição corporal das cabras foram registrados de cada tratamento. Resultados: SFCPT aumentou significativamente o rendimento do leite e o conteúdo de proteínas e sólidos, mas não houve diferença no conteúdo de gordura láctea. Conclusão: O tratamento com girassol e feno de grão de bico aumentou a produção de leite, o teor de proteína e os sólidos totais., Antecedentes: Los sistemas de producción animal en pequeña escala proveen alimentos de calidad para una demanda mundial creciente de proteina animal. Aunque estos sistemas ayudan a mejorar la calidad de vida rural y reducen la huella ambiental, se deben buscar nuevas estrategias de alimentación para incrementar la productividad animal. El girasol -originario de México- y el garbanzo -común en la zona de estudio- pueden usarse como alternativa para la alimentación de cabras lecheras. Objetivo: Evaluar el efecto de sustituir el heno de maíz con heno de girasol y garbanzo sobre el rendimiento y composición nutricional de la leche de cabra. Métodos: En este estudio participtivo, un total de 28 cabras multíparas lecheras Saanen fueron asignadas aleatoriamente a dos tratamientos (14 cabras a cada uno) durante 30 días en una finca pequeña. Dos semanas antes del experimento todas las cabras recibieron una dieta de adaptación. Un tratamiento (MZST) recibió una dieta convencional de heno de alfalfa (200g/cabra/día) y concentrado (400 g/cabra/día), más 600 g/cabra/día (50% de la ración) de heno de maíz. El segundo tratamiento (SFCPT) tuvo el mismo contenido de alfalfa y concentrado, pero con 600 g/cabra/día de heno de girasol-garbanzo. Se registraron los rendimientos y composición de leche, peso vivo y condición corporal de las cabras para cada tratamiento. Resultados: SFCPT incrementó significativamente el rendimiento de leche, y contenido de proteína y sólidos, pero no hubo diferencias en contenido de grasa. Conclusión: La suplementacion dietaria de cabras con heno de girasol y garbanzo aumenta la producción de leche y su contenido de proteína y sólidos totales en comparacion con el heno de maiz.

Background: Goat production has grown worldwide as a way to improve the quality of rural life and reduce the environmental footprint; nevertheless, there is a need to increase productivity through improved feeding strategies. The market demands healthier products with organoleptic characteristics similar to the traditional ones; thus, it is necessary to evaluate the effect of new forages for goats and its acceptance by consumers. Chemical and organoleptic composition of goat milk vary according to the diet which, in turn, affects the characteristics of cheese. Cheese texture, taste and smell are the most important sensory attributes for consumers. Objective: To evaluate the effect of substituting corn straw with sunflower hay associated with chickpea for dairy goats on yield, chemical composition and sensory acceptability of cheese, as well profitability. Methods: Twenty-eight Saanen dairy goats were randomly assigned to two treatments in a 30-day experiment on a small farm. The daily ration per goat in the MZST treatment (control treatment) consisted of alfalfa hay (200 g/goat/day) and concentrate (400 g/goat/day) plus 600 g/goat/day (50% of the ration) of corn straw. The SFCP treatment substituted corn straw with sunflower-chickpea hay; it had the same alfalfa and concentrate content, but with no corn straw and was added with 600 g/goat/day of sunflower-chickpea hay. The yield, composition and sensory evaluation of fresh cheese made with milk from each treatment were recorded, and the feeding costs and returns evaluated. Variables for the chemical composition of cheese were analyzed following a completely randomized design. Results: Significant differences were observed in cheese yield and all chemical composition variables. According to sensory evaluation, SFCP cheese had significantly higher scores for texture and odor but lower for taste and overall acceptability compared to MZST. In terms of profitability, SFCP increased feed costs by 5% but resulted in higher, Antecedentes: A produção de caprinos em todo o mundo tem crescido como forma de melhorar a qualidade de vida rural e reduzir a pegada ambiental; pero há uma necessidade de aumentar a produtividade através de estratégias de alimentação melhoradas. A crescente procura dos consumidores por produtos mais saudáveis mas com características organolépticas semelhantes aos tradicionais, tornou necessário desenvolver estratégias para satisfazer esta necessidade, pelo que é necessário avaliar o efeito de novas forrageiras nas dietas na sua aceitação pelos consumidores. A composição química e organoléptica do leite de cabra varia de acordo com a dieta, o que por sua vez afeta as características do queijo de leite de cabra. Entre os atributos sensoriais mais importantes para os consumidores estão textura, sabor e cheiro. Objetivo: Avaliar o efeito da substituição da palha de milho por feno de girassol associada ao grão-de-bico na alimentação de cabras leiteiras, em termos de rendimento, composição química e aceitabilidade sensorial do queijo, bem como desempenho econômico. Métodos: Vinte e oito cabras leiteiras Saanen foram distribuídas aleatoriamente em dois tratamentos em um experimento de 30 dias em uma fazenda de pequena escala. A ração diária por cabra no tratamento MZST (tratamento controle) consistia em feno de alfafa (200 g/cabra/dia) e concentrado (400 g/cabra/dia) mais 600 g/cabra/dia (50% da ração) de a palha de milho e o tratamento SFCP (tratamento substituiu o feno de girassol-grão moído) continham os mesmos teores de alfafa e concentrado, mas com 600 g/cabra/dia de feno de girassol-grão. O rendimento, a composição e a avaliação sensorial dos queijos in natura feitos com leite de cada tratamento foram registrados e os custos de alimentação e retornos avaliados. As variáveis de composição química dos queijos foram analisadas seguindo um delineamento inteiramente casualizado. Resultados: Houve diferenças significativas no rendimento do queijo e para todas as variáveis, Antecedentes: La producción caprina a nivel mundial ha crecido como una forma de mejorar la calidad de vida rural y reducir la huella ambiental, pero existe la necesidad de aumentar la productividad a través de mejores estrategias de alimentación. La creciente demanda de los consumidores por productos más sanos pero con características organolépticas similares a los tradicionales, ha hecho necesario desarrollar estrategias para satisfacer esta necesidad, por lo que es necesario evaluar el efecto de los nuevos forrajes en las dietas sobre su aceptación por parte de los consumidores. La composición química y organoléptica de la leche de cabra varía según la dieta, lo que a su vez afecta las características del queso de leche de cabra. Entre los atributos sensoriales más importantes para los consumidores se encuentran la textura, el sabor y el olor. Objetivo: Evaluar el efecto de la sustitución de paja de maíz por heno de girasol con garbanzo en la alimentación de cabras lecheras, en términos de rendimiento, composición química y aceptabilidad sensorial del queso, así como desempeño económico. Métodos: Se asignaron al azar veintiocho cabras lecheras Saanen a dos tratamientos en un experimento de 30 días en una granja a pequeña escala. La ración diaria por cabra en el tratamiento MZST (tratamiento control) consistió en heno de alfalfa (200 g/cabra/día) y concentrado (400 g/cabra/día) más 600 g/cabra/día (50% de la ración) de paja de maíz. El tratamiento SFCP sustituyó la paja de maiz por heno de girasol-garbanzo; tuvo el mismo contenido de alfalfa y concentrado, pero sin paja de maiz y con 600 g/cabra/día de heno girasol-garbanzo. Se registró el rendimiento, composición y evaluación sensorial de los quesos frescos elaborados con leche de cada tratamiento y se evaluaron los costos de alimentación y los rendimientos. Las variables de composición química de los quesos se analizaron siguiendo un diseño completamente aleatorizado. Resultados: Hubo diferencias significativas

A partir de una revisión de la figura de James S. Holmes como pensador pionero de la traductología contemporánea, el presente artículo marco identifica aspectos clave sobre la reflexión de lo queer en artefactos culturales traducidos. La exposición se divide en tres secciones relacionadas con el concepto de la mirada insumisa, elaborado por Alberto Mira, para reconocer los trayectos queer de la traductología desde su formación disciplinar pasando por el surgimiento de los enfoques de género hasta las investigaciones reunidas en este número especial. La segunda sección incluye un breve repaso sobre cómo se ha traducido la palabra queer en español y la manera en que esta se ha naturalizado en otra palabra, «cuir». La tercera sección incluye una organización en tres etapas sobre cómo se ha construido una traductología del género: traducción y género; traducción y queer/cuir, y traducción y transgénero. El texto concluye con una breve presentación de cada uno de los doce artículos reunidos en este número.

Through 16S rRNA amplicon metagenomic sequencing we identified a specialized benz(a)anthraquinone (BaAQ)-degrading subpopulation in a PAH-contaminated soil using sand-in-liquid microcosms. From the microcosms, a BaAQ-degrading microbial consortium was obtained by enrichment in sand-in-liquid cultures with BaAQ as sole carbon source. We combined shotgun metagenomics and metabolomic analysis to elucidate the BaAQ metabolic pathway and to provide an insight into the potential roles and interactions within the consortium members.
