Faint emission lines in the Galactic H II regions M16, M20 and NGC 3603

We present deep echelle spectrophotometry of the Galactic {\hii} regions M16, M20 and NGC 3603. The data have been taken with the Very Large Telescope Ultraviolet-Visual Echelle Spectrograph in the 3100 to 10400 \AA range. We have detected more than 200 emission lines in each region. Physical conditions have been derived using different continuum and line intensity ratios. We have derived He$^{+}$, C$^{++}$ and O$^{++}$ abundances from pure recombination lines as well as abundances from collisionally excited lines for a large number of ions of different elements. We have obtained consistent estimations of the temperature fluctuation parameter, {\ts}, using different methods. We also report the detection of deuterium Balmer lines up to D$\delta$ (M16) and to D$\gamma$ (M20) in the blue wings of the hydrogen lines, which excitation mechanism seems to be continuum fluorescence. The temperature fluctuations paradigm agree with the results obtained from optical CELs and the more uncertain ones from far IR fine structure CELs in NGC 3603, although, more observations covering the same volume of the nebula are necessary to obtain solid conclusions.Comment: 22 pages, 13 Tables, 7 Figures.

Institutional Metacognition as an Improvement Tool for Educational Management

A theoretical article is presented in order to describe and analyze an innovative methodology for educational management called institutional metacognition (IM), and it’s defined as a reflective and participatory process of an educative community to face conflicts, applying techniques that generate a conscious, dialogical and collaboratory learning in educational organizations. This perspective is relevant to school management field, because it implies the need to build a new vision of the school as an organization that not only teaches but also learns and therefore delivers new tools to current social needs of communication and participation that are stressed nowadays in educational organizations. This process can be used as a management tool for organizational change, to promote an effective learning, and to improve coexistence in schools; it would be used to manage organizational change, and it allows monitoring and accomplishing activities and conflicts that may occur. The characteristics of IM help to improve managing the organizational process when it is visualized as a part of improvement cycle. It presents benefits to collaborative learning, diversity, conflicts mediation and participatory diagnostics. On the other hand, there are challenges that hinder their application to improve relationships, both internally, as a new and unknown tool, and externally related to features of educational institutions

A low-mass planet candidate orbiting Proxima Centauri at a distance of 1.5 AU

Copyright © 2020 The Authors, some rights reserved; exclusive licensee American Association for the Advancement of Science. No claim to original U.S. Government Works. Distributed under a Creative Commons Attribution NonCommercial License 4.0 (CC BY-NC).Our nearest neighbor, Proxima Centauri, hosts a temperate terrestrial planet. We detected in radial velocities evidence of a possible second planet with minimum mass m c sin i c = 5.8 ± 1.9 M ⊕ and orbital period P c = 5.21 - 0.22 + 0.26 years. The analysis of photometric data and spectro-scopic activity diagnostics does not explain the signal in terms of a stellar activity cycle, but follow-up is required in the coming years for confirming its planetary origin. We show that the existence of the planet can be ascertained, and its true mass can be determined with high accuracy, by combining Gaia astrometry and radial velocities. Proxima c could become a prime target for follow-up and characterization with next-generation direct imaging instrumentation due to the large maximum angular separation of ~1 arc second from the parent star. The candidate planet represents a challenge for the models of super-Earth formation and evolution.Peer reviewedFinal Published versio

Immunization With Bovine Herpesvirus-4-Based Vector Delivering PPRV-H Protein Protects Sheep From PPRV Challenge

The Morbillivirus peste des petits ruminants virus (PPRV) is the causal agent of a highly contagious disease that mostly affects sheep and goats and produces considerable losses in developing countries. Current PPRV control strategies rely on live-attenuated vaccines, which are not ideal, as they cannot differentiate infected from vaccinated animals (DIVA). Recombinant vector-based vaccines expressing viral subunits can provide an alternative to conventional vaccines, as they can be easily paired with DIVA diagnostic tools. In the present work, we used the bovine herpesvirus-4-based vector (BoHV-4-A) to deliver PPRV hemagglutinin H antigen (BoHV-4-A-PPRV-H-ΔTK). Vaccination with BoHV-4-A-PPRV-H-ΔTK protected sheep from virulent PPRV challenge and prevented virus shedding. Protection correlated with anti-PPRV IgGs, neutralizing antibodies and IFN-γ-producing cells induced by the vaccine. Detection of antibodies exclusively against H-PPRV in animal sera and not against other PPRV viral proteins such as F or N could serve as a DIVA diagnostic test when using BoHV-4-A-PPRV-H-ΔTK as vaccine. Our data indicate that BoHV-4-A-PPRV-H-ΔTK could be a promising new approach for PPRV eradication programs

Predictive model for polishing times in mould finishing

El pulido, proceso final utilizado en la producción de piezas, es a menudo lento y se aplica manualmente. Normalmente define la rugosidad superficial y la precisión de la pieza. Se lleva a cabo utilizando partículas duras para producir la abrasión de la superficie de la pieza a pulir. En este documento se propone un modelo para predecir el progreso del frente de pulido. El modelo tiene en cuenta la topografía resultante antes de la mecanización a través de su curva de Abbott - Firestone, la velocidad relativa del material abrasivo, la fuerza aplicada, el material de la pieza y el tamaño de los granos abrasivos. Separa las aportaciones realizadas por el material de la pieza y el tipo abrasivo de la topografía previa. También muestra los valores recomendados para los diferentes parámetros de proceso a ser utilizados en la predicción de la evolución del frente de pulido en algunos materiales. Además se estima el tiempo de pulido necesario para eliminar completamente la topografía resultante del fresado utilizando una estrategia de perforación transversal. Por último, se muestra la predicción del modelo del frente de pulido, lo que confirma que el mecanismo de abrasión caracteriza dicho proceso.Polishing, the final process used in the production of parts, is often slow and often applied manually. It normally defines the surface roughness and part accuracy. It is performed using hard particles to produce abrasion of the workpiece surface to be polished. In this paper a model for predicting the progress of the polishing face is proposed. The model considers the topography resulting from prior mechanizing through its Abbott-Firestone curve, the relative speed of the abrasive material, the applied force, the workpiece material and the size of the abrasive grains. It separates the contributions made by the workpiece material and the abrasive type from the prior topography. It also shows recommended values for different process parameters to be used in predicting the evolution of the polishing front in some materials. Additionally, the polishing time required to completely remove the topography that results from ball milling using a cross drilling strategy is estimated. Finally, the model's correct prediction of the polished front is shown, confirming that the abrasion mechanism characterizes the sandpaper polishing process.Peer Reviewe

Unveiling the nature of IGR J17177-3656 with X-ray, NIR and Radio observations

We report on the first broad-band (1-200 keV) simultaneous Chandra-INTEGRAL observations of the recently discovered hard X-ray transient IGR J17177-3656 that took place on 2011, March 22, about two weeks after the source discovery. The source had an average absorbed 1-200 keV flux of about 8x10^(-10) erg cm^(-2) s^(-1). We extracted a precise X-ray position of IGR J17177-3656, RA=17 17 42.62, DEC= -36 56 04.5 (90% uncertainty of 0.6"). We also report Swift, near infrared and quasi simultaneous radio follow-up observations. With the multi-wavelength information at hand, we propose IGR J17177-3656 is a low-mass X-ray binary, seen at high inclination, probably hosting a black hole.Comment: 8 pages, 8 figures, accepted for publication in Ap

Draft Genome Sequence of a Multi-Metal Resistant Bacterium Pseudomonas putida ATH-43 Isolated from Greenwich Island, Antarctica

Indexación: Web of Science; Scopus.In this report we present the first draft genome sequence of a P. putida strain isolated from the Antarctic continent. The shotgun sequencing strategy, assembly, and subsequent annotation showed that the ATH-43 strain possesses a wide spectrum of genetic determinants involved in heavy metal and antibiotic resistance, apparently to cope with extreme oxidative stress conditions. P. putida ATH-43 genome now forms part of the 65 genomes of this species registered at the NCBI database (September, 2016) and it is highly related with the endophytic strain P. putida W619, which is also resistant to several heavy metals. Further characterization of multi-metal resistant psychrotrophic bacteria such as P. putida ATH-43 will be promising to develop novel strategies for heavy metal bioremediation in low temperature environments. All genome data has been submitted to NCBI.http://journal.frontiersin.org/article/10.3389/fmicb.2016.01777/ful
