El asociacionismo de mujeres, una experiencia individual y colectiva: la Asociación de Mujeres Las Tejedoras. Women’s move to asociate, an individual and collective experience: The Weaver Women Association

The feminist movement has been working for women’s rights since the beginning of the l9th century when a woman could not vote —in Spain this was not achieved until 1931—, nor hold public office, nor own property, exercise certain professions, obtain credit, obtain an education, etc. Little by little, vindications have touched more and more areas: politics, education, work. Today, women’s associations must again take up critical reflection of the fight for our objectives. The “Las Tejedoras” (The Weavers) Women’s Association has been working for four years for a different world, for a society different from the patriarchal model which perpetuates injustice, pain and loneliness. Weavers of dreams, goals and hopes. We weave “only support and solidarity among women”. Based upon experience and a specific project, the author presents reflections on the difficulties and challenges confronted by women’s collectives.El movimiento feminista viene trabajando en pro de los derechos de las mujeres desde principios del siglo XIX cuando has mujeres no podíamos votar —-en España no se consiguió hasta 1931—-, ni ocupar cargos públicos, ni tener propiedades, ejercer ciertas profesiones, obtener un crédito, acceder a la enseñanza, etc. Poco a poco las reivindicaciones iban abarcando más y más espacios: política, educación, empleo. Hoy las asociaciones de Mujeres debemos retomar la reflexión crítica de la lucha por nuestros objetivos. La Asociación de Mujeres Las Tejedoras lleva trabajando cuatro años en la lucha por un mundo diferente, por una sociedad diferente al modelo patriarcal que perpetua las injusticias, el dolor y la soledad.

Here, we review the available information about the distribution, abundance and diversity of this member of the Bacteroidetes

Políticas e práticas inclusivas nas escolas: um estudo de sua implementação e relacionamento a partir de uma perspectiva gerencial

In the current context, educational centers are expected to be spaces of collaborative organization that promote inclusive education, implementing initiatives and strategies derived from educational management. In this regard, the objective of this study is to analyze the establishment of inclusive policies and practices in Costa Rican educational centers from the perspective of the administrators. The research was carried out using a quantitative methodology, with an ex post facto and cross-sectional design. In addition, data collection was carried out with an online questionnaire applied to a simple probability sample of 146 administrators. The results show that the management implemented in the educational centers considers to a certain extent the application of inclusive policies and practices. In addition, there is a strong and positive correlation between inclusive education policies and the curricular and administrative practices implemented. In other words, the greater the presence of inclusive policies, the better the curricular and administrative practices.En el contexto actual, se espera que los centros educativos sean espacios de organización colaborativa que promuevan la educación inclusiva, implementando iniciativas y estrategias derivadas de la gestión educativa. Al respecto, el presente estudio tiene el objetivo de analizar el establecimiento de políticas y prácticas inclusivas en los centros educativos costarricenses desde la perspectiva de las personas gestoras. La investigación se llevó a cabo desde una metodología cuantitativa, con un diseño ex post facto y transversal. Además, la recogida de datos se realizó con un cuestionario en línea aplicado a una muestra probabilística simple de 146 personas directivas. Los resultados evidencian que la gestión implementada en los centros educativos considera en cierta medida la aplicación de políticas y prácticas inclusivas. Además, se obtiene una correlación fuerte y positiva entre las políticas de educación inclusiva y las prácticas curriculares y administrativas implementadas. Es decir, que a mayor presencia de políticas inclusivas mejoran tanto las prácticas curriculares como las administrativas.No contexto atual, espera-se que os centros educacionais sejam espaços de organização colaborativa que promovam a educação inclusiva, implementando iniciativas e estratégias derivadas da gestão educacional.

Structural design and particle size examination on NiO-CeO2 catalysts supported on 3D-printed carbon monoliths for CO2 methanation

3D-printed high-surface carbon monoliths have been fabricated and tested as catalyst supports of CO2 metha nation active phases (NiO-CeO2, 12 wt% Ni). The carbon carriers show a developed microporosity and good adherence to the catalytic phases of NiO-CeO2, showing great stability and cyclability. Two monolith designs were used: a conventional parallel-channeled structure (honeycomb) and a complex 3D network of non-linear channels built upon interconnected circular sections (circles), where flow turbulences along the reactant gas path are spurred. The effect of the active phases particle size on the catalyst distribution and the overall per formance has been assessed by comparing NiO-CeO2 nanoparticles of 7 nm verage (Np), with a reference counterpart of uncontrolled structure (Ref). The improved radial gases diffusion in the circles monolith design is confirmed, and nanoparticles show enhanced CO2 methanation activity than the uncontrolled-size active phase at low temperatures ( 300 ºC). SEM and Hg porosimetry evidence that nanoparticles are deposited at deeper penetration through the narrow micropores of the carbon matrix of the monolithic supports, which tend to accumulate on the channels surface remaining more accessible to the reactant molecules. Altogether, this study examines the impact of the channel tortuosity and the active phase sizing on the CO2 methanation activity, serving as ground knowledge for the further rational and scalable fabrication of carbon monolith for catalytic applications.The authors thank the financial support of the Spanish Ministry of Science and Innovation (Projects PID2019-105960RB-C22, TED2021-129216B-I00 and PDC2022-133839-C22), Generalitat Valenciana (Projects CIPROM/2021/74, MFA/2022/036), and the EU NextGener ation (PRTR-C17.I1).

Evaluación del interés de productores ganaderos en el control selectivo y eficiente de predadores en la Patagonia austral

Sheep ranchers (n = 90) were surveyed to evaluate their interest in the incorporation of predator selective control methods. We based our survey on the characterization of the sheep ranching system of Santa Cruz province and its relationship with culpeo fox (Lycalopex culpaeus) predation. For a large percentage of producers (73%), the carrying capacity at present is under the optimal, which is consistent with the fact that sheep ranching represents only a part of their income. Lamb losses due to culpeo foxes predation vary between 5% and 50% of the annual lamb production, and these percentages did not vary during the last years in spite of the perceiving, by 53% of ranchers, of an increment in foxes abundance. Ranchers tend to exaggerate real losses of their lambs due to predation, although they recognize that there are other causes that could facilitate it. Nevertheless, fox control, including poisoning as a method, is still a current practice even in those ranches without sheep. The 90% of the sheep ranchers showed a good willingness to replace their current practices by selective and efficient control methods. This is an important point to encourage the use of selective control methods, like toxic baits delivered in a selective way, which would allow the abandonment of the traditional practices so dangerous to biodiversity conservationElaboramos una encuesta con el fin de evaluar el interés de los productores ganaderos por incorporar prácticas selectivas de control basándonos en la caracterización del sistema de producción ganadera de Santa Cruz y su relación con la predación por el zorro colorado (Lycalopex culpaeus). Para los encuestados (n = 90) la carga ovina actual está por debajo de la óptima, lo que es consistente con el hecho de que para la mayoría (73%) la ganadería solo representa una parte de sus ingresos. El nivel de pérdida de corderos por predación de zorros colorados varía entre el 5% y el 50% de la producción anual y esta tasa se ha mantenido en los últimos años, a pesar de que el 56% de los encuestados percibe un aumento en la abundancia de zorros en sus campos en los últimos 10 años. Las actitudes negativas de los productores hacia el zorro colorado se reflejaron en el hecho de que su control continúa siendo una práctica habitual para el 73% de los encuestados incluso en establecimientos sin producción. El uso de veneno es o ha sido utilizado por la mayoría de los productores (74%) a pesar de su prohibición. Sin embargo, el 91% de los encuestados estaría dispuesto a reemplazar sus prácticas por métodos de control selectivos y eficientes. Este es un punto importante para incentivar el uso de métodos alternativos de control, como cebos tóxicos administrados selectivamente, lo que permitiría el abandono de las prácticas tradicionales tan nocivas para la conservación de la biodiversidad

Intraoperative indocyanine green (ICG) angiography of the parathyroids glands in prediction of post-thyroidectomy hypocalcemia: Diagnostic accuracy of the ICG score 2 versus the 4-ICG score

Introducción: la angiografía de las glándulas paratiroides con verde de indocianina (ICG) es útil para predecir la hipocalcemia postiroidectomía. En este estudio se ha comparado la exactitud diagnóstica del sistema ICG-2, basado en la presencia de glándulas bien perfundidas (puntuación igual a 2), con el sistema ICG-4 basado en la suma del valor de la puntuación de las 4 glándulas. Métodos: un total de 50 pacientes (66% mujeres, mediana de edad: 49,4 años) fueron operadas practicándose una tiroidectomía total con identificación de las 4 glándulas paratiroides. El grado de la ICG se clasificó como 0: color negro (no vascularizada), 1: color gris/heterogéneo (parcialmente vascularizada) y 2: color blanco (bien vascularizada). Resultados: la exactitud diagnóstica de ICG-4 para un punto de corte ≤ 3 fue del 85% (intervalo de confianza del 95%: 70,9-92,8), inferior al 92% (80,8-97,8) del ICG-2. Con ambas puntuaciones se detectaron 2 casos de falsos negativos, pero las tasas de falsos positivos fueron menores con el ICG-2 (18,2 vs. 57,1%). Conclusiones: el sistema ICG-2 predice la función paratiroidea en el postoperatorio inmediato mejor que el ICG-4 para valores de punto de corte ≤ 2 y ≤ 3

Brain Perihematoma Genomic Profile Following Spontaneous Human Intracerebral Hemorrhage

BACKGROUND: Spontaneous intracerebral hemorrhage (ICH) represents about 15% of all strokes and is associated with high mortality rates. Our aim was to identify the gene expression changes and biological pathways altered in the brain following ICH. METHODOLOGY/PRINCIPAL FINDINGS: Twelve brain samples were obtained from four deceased patients who suffered an ICH including perihematomal tissue (PH) and the corresponding contralateral white (CW) and grey (CG) matter. Affymetrix GeneChip platform for analysis of over 47,000 transcripts was conducted. Microarray Analysis Suite 5.0 was used to process array images and the Ingenuity Pathway Analysis System was used to analyze biological mechanisms and functions of the genes. We identified 468 genes in the PH areas displaying a different expression pattern with a fold change between -3.74 and +5.16 when compared to the contralateral areas (291 overexpressed and 177 underexpressed). The top genes which appeared most significantly overexpressed in the PH areas codify for cytokines, chemokines, coagulation factors, cell growth and proliferation factors while the underexpressed codify for proteins involved in cell cycle or neurotrophins. Validation and replication studies at gene and protein level in brain samples confirmed microarray results. CONCLUSIONS: The genomic responses identified in this study provide valuable information about potential biomarkers and target molecules altered in the perihematomal regions
