Neutron-Capture elements in planetary nebulae: first detections of near-Infrared [Te III] and [Br V] emission lines

We have identified two new near-infrared emission lines in the spectra of planetary nebulae (PNe) arising from heavy elements produced by neutron capture reactions: [Te III] 2.1019 $\mu$m and [Br V] 1.6429 $\mu$m. [Te III] was detected in both NGC 7027 and IC 418, while [Br V] was seen in NGC 7027. The observations were obtained with the medium-resolution spectrograph EMIR on the 10.4m Gran Telescopio Canarias at La Palma, and with the high-resolution spectrograph IGRINS on the 2.7m Harlan J. Smith telescope at McDonald Observatory. New calculations of atomic data for these ions, specifically A-values and collision strengths, are presented and used to derive ionic abundances of Te$^{2+}$ and Br$^{4+}$. We also derive ionic abundances of other neutron-capture elements detected in the near-infrared spectra, and estimate total elemental abundances of Se, Br, Kr, Rb, and Te after correcting for unobserved ions. Comparison of our derived enrichments to theoretical predictions from AGB evolutionary models shows reasonable agreement for solar metallicity progenitor stars of $\sim$2 - 4 M$_{\odot}$. The spectrally-isolated [Br V] 1.6429 $\mu$m line has advantages for determining nebular Br abundances over optical [Br III] emission lines that can be blended with other features. Finally, measurements of Te are of special interest because this element lies beyond the first peak of the s-process, and thus provides new leverage on the abundance pattern of trans-iron species produced by AGB stars.Comment: 9 pages, 1 figure, 4 tables.

Supplementation of honey bee production colonies with a native beneficial microbe mixture

Honey bee colonies form a complex superorganism, with individual and social immune defences that control overall colony health. Sometimes these defences are not enough to overcome infections by parasites and pathogens. For that reason, several studies have been conducted to evaluate different strategies to improve honey bee health. A novel alternative that is being studied is the use of beneficial microbes. In a previous study, we isolated and characterised bacterial strains from the native gut microbiota of honey bees. Four Apilactobacillus kunkeei strains were mixed and administered in laboratory models to evaluate their potential beneficial effect on larvae and adult bees. This beneficial microbe mixture was safe; it did not affect the expression of immune-related genes, and it was able to decrease the mortality caused by Paenibacillus larvae infection in larvae and reduced the Nosema ceranae spore number in infected adult honey bees. In the present study, we aimed to delve into the impact of the administration of this beneficial microbe mixture on honey bee colonies, under field conditions. The mixture was administered in sugar syrup using lyophilised bacterial cells or fresh cultures, by aspersion or sprayed and feeder, once a week for three consecutive weeks, in autumn or spring 2015, 2017 and 2019. Colony strength parameters were estimated before the administration, and one and three months later. Simultaneously different samples were collected to evaluate the infection levels of parasites and pathogens. The results showed that dministering the beneficial microbe mixture decreased or stabilised the infection by N. ceranae or Varroa destructor in some trials but not in others. However, it failed to improve the colony’s strength parameters or honey production. Therefore, field studies can be a game-changer when beneficial microbes for honey bees are tested, and meticulous studies should be performed to test their effectivenessAgencia Nacional de Investigación e InnovaciónInstituto Nacional de Investigación Agropecuari

The significance of 'role-play' and 'instruction-based performance' as modes of teaching, collaborating and performing with/for participating audiences

ZU-UK distilled strategies developed for their all-night participatory performance, Hotel Medea (2006-2012), into a “dramaturgy of participation” (Lopes Ramos and Maravala 2016): a training and performance-making approach drawing on combined non-Western, non-commercial praxes from which the company has emerged (including Brazilian, Eastern European, Persian and Indian body-based and spiritual traditions). Subsequently, ZU-UK’s work has moved further beyond the confines of theatre and performer-training but continues to focus on participation and working with emerging artists towards generating post-immersive collaborative models that reject neo-liberal pressures for scale, reproducibility, and escape, in favor of intimacy, specificity and awareness. We examine “role-play” and “instruction-based performance” as modes of teaching and performing that, in conjunction with social role theory after Goffman (1959), become strategies for political activation. Examples used demonstrate the analogue of positioning audiences and students as makers of their own experiences and compelling them to think about who work is by, with, and for

Influence of desalinator wastewater for the cultivation of <i>Arthrospira platensis</i>. Fatty acids profile

The need for a desalination processes in northeastern Brazil is due to the salinity of its water sources. However, these processes produce residues with high saline concentrations and a significant environmental impact. These wastewaters can be used for Arthrospira platensis cultivation. This work aimed to cultivate Arthrospira platensis in three different media: Paoletti Synthetic Medium (PSM), Salinated Water Medium (SWM) and Desalinator Wastewater Médium (DWWM). Microalgae were cultivated under controlled conditions, in 4 L photobioreactors, 30±1°C, 12 hours of light/dark photoperiod provided by fluorescent lamps at a light intensity of 140 μmol• m–2•s–1 and constant bubbling of air (0.5 L•L–1 •min–1). The effect of different media on cell concentration, productivity, total content of lipids and fatty acids profile was verified. Higher cell concentration, as well as higher productivity was observed in DWWM: 4.954 (±0.554) g•L–1 and 0.225 (±0.042) g•L–1 •day–1, respectively. Concerning total lipids, the contents of 4.54% and 4.69% were observed in DWWM and SWM, respectively. High levels of saturated fatty acids were observed in both treatments. Concerning γ-linolenic acid, the contents of 13.09% (DWWM) and 11.95% (SWM) were found.En la región nordeste de Brasil, debido a la elevada salinidad de los acuíferos, existe la necesidad de utilizar procesos de desalación. Sin embargo, estos procesos generan residuos con alta concentración salina, con significativo impacto ambiental. El objetivo de este trabajo fue el cultivo de Arthrospira platensis en tres medios de cultivo diferentes: medio de Paoletti, medio de agua salinizada y medio de agua de desecho obtenida en el proceso de desalación de acuíferos. Las microalgas fueron cultivadas en laboratorio, con condiciones controladas, en fotobiorreactores de 4 L, a 30±1°C y periodos de 12 horas de claridad/oscuridad con iluminación de 140 μmol•m–2•s–1 e inyección constante de aire (0,5 L•L–1•min–1). Fue verificado el efecto de los diferentes medios en la concentración celular, productividad, contenido total de lípidos y perfil de ácidos grasos. La mayor concentración celular, así como la productividad máxima fueron encontradas en el medio de agua de desecho de desalación, 4,954 (±0,554) g•L–1 y 0,225 (±0,042) g•L–1•día–1 respectivamente. En relación a los lípidos totales, se encontraron valores de 4,54% en el medio de agua de desecho de desalación y 4,69% en el medio de agua salinizada. En cuanto a los ácidos grasos, se obtuvieron altos índices de ácidos grasos saturados con ambos tratamientos. Con relación al ácido γ-linolénico, se encontró en un 13,09% en el medio de agua de desecho de desalación y en un 11,95% en el medio de agua salinizada

The Effect of Galaxy Interactions on Molecular Gas Properties

© 2018. The American Astronomical Society. All rights reserved.Galaxy interactions are often accompanied by an enhanced star formation rate (SFR). Since molecular gas is essential for star formation, it is vital to establish whether and by how much galaxy interactions affect the molecular gas properties. We investigate the effect of interactions on global molecular gas properties by studying a sample of 58 galaxies in pairs and 154 control galaxies. Molecular gas properties are determined from observations with the JCMT, PMO, and CSO telescopes and supplemented with data from the xCOLD GASS and JINGLE surveys at 12CO(1-0) and 12CO(2-1). The SFR, gas mass (), and gas fraction (f gas) are all enhanced in galaxies in pairs by ∼2.5 times compared to the controls matched in redshift, mass, and effective radius, while the enhancement of star formation efficiency (SFE ≡SFR/) is less than a factor of 2. We also find that the enhancements in SFR, and f gas, increase with decreasing pair separation and are larger in systems with smaller stellar mass ratio. Conversely, the SFE is only enhanced in close pairs (separation <20 kpc) and equal-mass systems; therefore, most galaxies in pairs lie in the same parameter space on the SFR- plane as controls. This is the first time that the dependence of molecular gas properties on merger configurations is probed statistically with a relatively large sample and a carefully selected control sample for individual galaxies. We conclude that galaxy interactions do modify the molecular gas properties, although the strength of the effect is dependent on merger configuration.Peer reviewedFinal Accepted Versio

“What if There's Something Wrong with Her?”‐How Biomedical Technologies Contribute to Epistemic Injustice in Healthcare

While there is a steadily growing literature on epistemic injustice in healthcare, there are few discussions of the role that biomedical technologies play in harming patients in their capacity as knowers. Through an analysis of newborn and pediatric genetic and genomic sequencing technologies (GSTs), I argue that biomedical technologies can lead to epistemic injustice through two primary pathways: epistemic capture and value partitioning. I close by discussing the larger ethical and political context of critical analyses of GSTs and their broader implications for just and equitable healthcare delivery

Variations in seasonal solar insolation are associated with a history of suicide attempts in bipolar I disorder

Background: Bipolar disorder is associated with circadian disruption and a high risk of suicidal behavior. In a previous exploratory study of patients with bipolar I disorder, we found that a history of suicide attempts was associated with diferences between winter and summer levels of solar insolation. The purpose of this study was to confrm this fnding using international data from 42% more collection sites and 25% more countries. Methods: Data analyzed were from 71 prior and new collection sites in 40 countries at a wide range of latitudes. The analysis included 4876 patients with bipolar I disorder, 45% more data than previously analyzed. Of the patients, 1496 (30.7%) had a history of suicide attempt. Solar insolation data, the amount of the sun's electromagnetic energy striking the surface of the earth, was obtained for each onset location (479 locations in 64 countries). Results: This analysis confrmed the results of the exploratory study with the same best model and slightly better statistical signifcance. There was a signifcant inverse association between a history of suicide attempts and the ratio of mean winter insolation to mean summer insolation (mean winter insolation/mean summer insolation). This ratio is largest near the equator which has little change in solar insolation over the year, and smallest near the poles where the winter insolation is very small compared to the summer insolation. Other variables in the model associated with an increased risk of suicide attempts were a history of alcohol or substance abuse, female gender, and younger birth cohort. The winter/summer insolation ratio was also replaced with the ratio of minimum mean monthly insolation to the maximum mean monthly insolation to accommodate insolation patterns in the tropics, and nearly identical results were found. All estimated coefcients were signifcant at p<0.01. Conclusion: A large change in solar insolation, both between winter and summer and between the minimum and maximum monthly values, may increase the risk of suicide attempts in bipolar I disorder. With frequent circadian rhythm dysfunction and suicidal behavior in bipolar disorder, greater understanding of the optimal roles of daylight and electric lighting in circadian entrainment is needed.
