Low X-Ray Luminosity Galaxy Clusters. II. Optical properties and morphological content at 0.18 < z < 0.70

This is the second of a series of papers on low X-ray luminosity galaxy clusters, in which we present the $r^\prime$, $g^\prime$ and $i^\prime$ photometry obtained with GMOS-IMAGE at Gemini North and South telescopes for seven systems in the redshift range of 0.18 to 0.70. Optical magnitudes, colours and morphological parameters, namely, concentration index, ellipticity and visual morphological classification, are also given. At lower redshifts, the presence of a well-defined red cluster sequence extending by more than 4 magnitudes showed that these intermediate-mass clusters had reached a relaxed stage. This was confirmed by the small fraction of blue galaxy members observed in the central regions of $\sim$ 0.75 Mpc. In contrast, galaxy clusters at higher redshifts had a less important red cluster sequence. We also found that the galaxy radial density profiles in these clusters were well fitted by a single power law. At 0.18 $<$ z $<$ 0.70, we observed an increasing fraction of blue galaxies and a decreasing fraction of lenticulars, with the early-type fraction remaining almost constant. Overall, the results of these intermediate-mass clusters are in agreement with those for high mass clusters.Comment: 16 pages, 13 figures, 5 tables. Accepted for publication in MNRA

Aprovechamiento de lodos férricos procedentes de plantas potabilizadoras de agua como adsorbentes de malos olores

Los malos olores emitidos por las estaciones de tratamiento de aguas residuales (EDARs) han sido motivo de gran preocupación, especialmente debido a la alarmante proximidad entre las EDARs y las áreas residenciales. Dichos olores perjudican inevitablemente la salud pública y la calidad de la vida de las comunidades locales (Fan et al., 2020. https://doi.org/10.1016/j.watres.2020.115915). Además, las políticas ambientales y del cambio climático de la UE demuestran una creciente atención por la calidad del medio ambiente (EEA, 2019. www.eea.europa.eu). Al mismo tiempo, en las estaciones de tratamiento de aguas potables (ETAPs), la adición de cloruro férrico como coagulante para eliminar el color y la turbidez del agua (Ebrahimi et al., 2015. https://doi.org/10.1080/19443994.2014.928796), genera una gran cantidad de lodo férrico en las ETAPs que la normativa actual obliga a la gestionar. La gestión más utilizada es su deposición en vertedero controlado, que es costoso y no es compatible con los conceptos de economía circular y desarrollo sostenible. Por todo ello, el objetivo principal de este estudio, es el aprovechamiento de lodos férricos generados en las ETAPs como adsorbentes para la eliminación de los malos olores en las EDARs. La caracterización físico–química de los lodos férricos ha sido realizada mediante las técnicas de FRX, DRX, BET, SEM-EDAX, TEM y XPS y con el fin de trabajar en columnas de adsorción, se estudió la transformación del lodo férrico en un material estructurado (tipo pellet) para poder ser utilizado como relleno de las mismas. Una vez sintetizados los pellets, se estudió el proceso de adsorción de sulfuro de hidrógeno (H2S) variando las condiciones de reacción, principalmente humedad relativa, caudales y composición de la mezcla gaseosa.Universidad de Málaga.

ID1 and ID4 Are Biomarkers of Tumor Aggressiveness and Poor Outcome in Immunophenotypes of Breast Cancer

Inhibitor of differentiation (ID) proteins are a family of transcription factors that contribute to maintaining proliferation during embryogenesis as they avoid cell differentiation. Afterward, their expression is mainly silenced, but their reactivation and contribution to tumor development have been suggested. In breast cancer (BC), the overexpression of ID1 has been previously described. However, whether the remaining ID genes have a specific role in this neoplasia is still unclear. We studied the mRNA expression of all ID genes by q RT-PCR in BC cell lines and 307 breast carcinomas, including all BC subtypes. Our results showed that ID genes are highly expressed in all cell lines tested. However, ID4 presented higher expression in BC cell lines compared to a healthy breast epithelium cell line. In accordance, ID1 and ID4 were predominantly overexpressed in Triple-Negative and HER2-enriched samples. Moreover, high levels of both genes were associated with larger tumor size, histological grade 3, necrosis and vascular invasion, and poorer patients’ outcomes. In conclusion, ID1 and ID4 may act as biomarkers of tumor aggressiveness and worse prognosis in breast cancer, and they could be used as potential targets for new treatments discover.This research was funded by the Alicante Institute for Health and Biomedical Research (ISABIAL) (UGP 16-149 and UGP 180184) and Navarro-Tripodi Foundation (BOLA00150).

Effect of Basic Promoters on Porous Supported Alumina Catalysts for Acetins Production

A facile strategy for the design of porous supports was obtained by modifying the sol-gel method followed by the wet impregnation technique. In this respect, herein, the acidity of the γ-Al2O3 phase was modulated by adding basic MgO, La2O3 or ZnO promoters to form binary supported catalysts. The Ni and Co dispersion on the supports associated with their tunable acidity and morphologies resulted in highly porous supported alumina-based catalysts. The physicochemical properties of the solids were comprehensively investigated by XRD, textural properties, Raman and FTIR spectroscopy, SEM-EDS, TEM, EPR and XPS analyses. The catalytic performances in the esterification of glycerol in the presence of acetic acid (EG) for the acetins production were evaluated. The highly dispersed NiO and Co3O4 active species on binary porous supports produced synergistic effects appearing to be the reason for the activity of the solids in the EG reaction. Under the optimized reaction conditions, NiCo/MgO-Al2O3 was found to be a robust solid with superior catalytic performance and improved stability in four reaction cycles with 65.0% of glycerol conversion with an exclusive selectivity of 53% for triacetin. The presence of Co2+/Co3+ and Ni2+ strongly interacting with the spinel γ-Al2O3 and MgAl2O4 phases, the latter having a large number of lattice oxygen species, was considered another active component besides those of Ni and Co in the esterification of glycerol.This work is supported by Funcap (Grant n° PS1-0186-00346.01.00/21).

Analysis of candidates for interacting galaxy clusters: I. A1204 and A2029/A2033

Merging galaxy clusters allow for the study of different mass components, dark and baryonic, separately. Also, their occurrence enables to test the ΛCDM scenario, which can be used to put constraints on the selfinteracting cross-section of the dark-matter particle. It is necessary to perform a homogeneous analysis of these systems. Hence, based on a recently presented sample of candidates for interacting galaxy clusters, we present the analysis of two of these cataloged systems. In this work, the first of a series devoted to characterizing galaxy clusters in merger processes, we perform a weak lensing analysis of clusters A1204 and A2029/2033 to derive the total masses of each identified interacting structure together with a dynamical study based on a two-body model. We also describe the gas and the mass distributions in the field through a lensing and an X-ray analysis. This is the first of a series of works which will analyze these type of system in order to characterize them. Neither merging cluster candidate shows evidence of having had a recent merger event. Nevertheless, there is dynamicalevidence that these systems could be interacting or could interact in the future. It is necessary to include more constraints in order to improve the methodology of classifying merging galaxy clusters.Characterization of these clusters is important in order to properly understand the nature of these systems and their connection withdynamical studies.Fil: Gonzalez, Elizabeth Johana.

Results and evaluation of the expansion of a model of comprehensive care for Chagas disease within the National Health System: The Bolivian Chagas network

Background: Most people with chronic Chagas disease do not receive specific care and therefore are undiagnosed and do not receive accurate treatment. This manuscript discusses and evaluates a collaborative strategy to improve access to healthcare for patients with Chagas in Bolivia, a country with the highest prevalence of Chagas in the world. Methods: With the aim of reinforcing the Chagas National Programme, the Bolivian Chagas Platform was born in 2009. The first stage of the project was to implement a vertical pilot program in order to introduce and consolidate a consensual protocol-based healthcare, working in seven centers (Chagas Platform Centers). From 2015 on the model was extended to 52 primary healthcare centers, through decentralized, horizontal scaling-up. To evaluate the strategy, we have used the WHO ExpandNet program. Results: The strategy has significantly increased the number of patients cared for, with 181,397 people at risk of having T. cruzi infection tested and 57,871 (31·9%) new diagnostics performed. In those with treatment criteria, 79·2% completed the treatment. The program has also trained a significant number of health personnel through the specific Chagas guidelines (67% of healthcare workers in the intervention area). Conclusions: After being recognized by the Chagas National Programme as a healthcare model aligned with national laws and priorities, the Bolivian platform of Chagas as an innovation, includes attributes that they have made it possible to expand the strategy at the national level and could also be adapted in other countries

Survival Strategies and Emotions. Informal Union and Marriage on the Pacific Slope of Colonial Central America

The purpose of this article is to examine how survival needs shaped the behavior of the inhabitants of the interior of the Central American Pacific region between the second half of the 18th century and the end of the colonial era, a period of particular social and geographical mobility. For this, information obtained from Central American archives is analyzed through the lens of survival strategies, unions (formals or not) as a resource and the role of emotions in the process. As a result of this research, it is deduced that affective (emotions) and biological (reproductive capacities) components, until now little treated by Central American historiography, were key elements in the development of Central American colonial society
