Quantifying the Relationship between Moreton–Ramsey Waves and “EIT Waves” Using Observations of Four Homologous Wave Events
Authors: Long David M. , Jenkins Jack , Valori Gherardo 
Published: September 2019

Abstract
Freely propagating global waves in the solar atmosphere are commonly observed using extreme ultraviolet passbands (EUV or “EIT waves”), and less regularly in H-alpha (Moreton–Ramsey waves). Despite decades of research, joint observations of EUV and Moreton–Ramsey waves remain rare, complicating efforts to quantify the connection between these phenomena. We present observations of four homologous global waves originating from the same active region between 2014 March 28 and 30 and observed using both EUV and H-alpha data. Each global EUV wave was observed by the Solar Dynamics Observatory, with the associated Moreton–Ramsey waves identified using the Global Oscillations Network Group network. All of the global waves exhibit high initial velocity (e.g., 842–1388 km s−1 in the 193 Å passband) and strong deceleration (e.g., −1437 to −782 m s−2 in the 193 Å passband) in each of the EUV passbands studied, with the EUV wave kinematics exceeding those of the Moreton–Ramsey wave. The density compression ratio of each global wave was estimated using both differential emission measure and intensity variation techniques, with both indicating that the observed waves were weakly shocked with a fast magnetosonic Mach number slightly greater than one. This suggests that, according to current models, the global coronal waves were not strong enough to produce Moreton–Ramsey waves, indicating an alternative explanation for these observations. Instead, we conclude that the evolution of the global waves was restricted by the surrounding coronal magnetic field, in each case producing a downward-angled wavefront propagating toward the north solar pole, which perturbed the chromosphere and was observed as a Moreton–Ramsey wave.
Using the Extragalactic Gamma-Ray Background to Constrain the Hubble Constant and Matter Density of the Universe
Authors: Zeng Houdun , Yan Dahai 
Published: September 2019

Abstract
The attenuation produced by extragalactic background light (EBL) in γ-ray spectra of blazars has been used to constrain the Hubble constant (H
0) and matter density (Ωm) of the universe. We propose to estimate H
0 and Ωm using the well-measured >10 GeV extragalactic γ-ray background (EGB). This suggestion is based on the fact that the >10 GeV EGB is totally explained by the emissions from blazars, and an EBL-absorption cutoff occurs at ∼50 GeV in the EGB spectrum. We fit the >10 GeV EGB data with modeled EGB spectrum. This results in

and

. Note that the uncertainties may be underestimated due to the limit of our realization for EBL model. H
0 and Ωm are degenerate in our method. Independent determination of Ωm by other methods would improve the constraint on H
0.

Abstract
Photodissociation by ultraviolet radiation is the key destruction pathway for CS in photon-dominated regions, such as diffuse clouds. However, the large uncertainties of photodissociation cross sections and rates of CS, resulting from a lack of both laboratory experiments and theoretical calculations, limit the accuracy of calculated abundances of S-bearing molecules by modern astrochemical models. Here we show a detailed ab initio study of CS photodissociation. Accurate potential energy curves of CS electronic states were obtained by choosing an active space CAS(8,10) in MRCI+Q/aug-cc-pV(5+d)Z calculation with additional diffuse functions, with a focus on the B and C
1Σ+ states. Cross sections for both direct photodissociation and predissociation from the vibronic ground state were calculated by applying the coupled-channel method. We found that the C − X (0 − 0) transition has extremely strong absorption due to a large transition dipole moment in the Franck–Condon region, and the upper state is resonant with several triplet states via spin–orbit couplings, resulting in predissociation to the main atomic products C (3
P) and S (1
D). Our new calculations show that the photodissociation rate under the standard interstellar radiation field is 2.9 × 10−9 s−1, with a 57% contribution from C − X (0 − 0) transition. This value is larger than that adopted by the Leiden photodissociation and photoionization database by a factor of 3.0. Our accurate ab initio calculations will allow more secure determination of S-bearing molecules in astrochemical models.
Role of Planetary Obliquity in Regulating Atmospheric Escape: G-dwarf versus M-dwarf Earth-like Exoplanets

Published: September 2019

Abstract
We present a three-species (H+, O+ and e−) multi-fluid magnetohydrodynamic model, endowed with the requisite upper-atmospheric chemistry, that is capable of accurately quantifying the magnitude of oxygen ion losses from “Earth-like” exoplanets in habitable zones, whose magnetic and rotational axes are roughly coincidental with one another. We apply this model to investigate the role of planetary obliquity in regulating atmospheric losses from a magnetic perspective. For Earth-like exoplanets orbiting solar-type stars, we demonstrate that the dependence of the total atmospheric ion loss rate on the planetary (magnetic) obliquity is relatively weak; the escape rates are found to vary between 2.19 × 1026 s−1 to 2.37 × 1026 s−1. In contrast, the obliquity can influence the atmospheric escape rate (∼1028 s−1) by more than a factor of 2 (or 200%) in the case of Earth-like exoplanets orbiting late-type M-dwarfs. Thus, our simulations indicate that planetary obliquity may play a weak-to-moderate role insofar as the retention of an atmosphere (necessary for surface habitability) is concerned.

Published: September 2019

Objectives The aim of this study was to explore drinking culture and drinking situations that employers and employees encounter in the grey zone between work and leisure, and identify what might affect employees’ risky drinking behaviour. Methods We used eight focus groups to interview 61 core company informants from eight Norwegian companies (private and public sector) participating in the WIRUS – Workplace-based interventions preventing risky alcohol use and sick leave – project. The informants represented employers and employees with a diversity of roles at multiple organisational levels. The transcribed interviews were analysed by applying a phenomenological hermeneutical approach. Results The analysis revealed six dimensions of drinking culture representing potentially risky drinking behaviour in situations that fall in the grey zone between work and leisure: (1) “Who invited me?” (Degree of obligation towards inviter), (2) “Do I have to participate?” (Degree of participation volunteerism), (3) “To drink or not to drink?” (Degree of drinking volunteerism), (4) “Work talk or small talk?” (Degree of work-related conversation), (5) “Are there any drinking rules to follow?” (Degree of regulation), and (6) “The influence of being away from home” (degree of distance to home). Conclusions The findings reveal that employers and employees’ experience of drinking culture can be categorised as six different “shades of grey”. The grey zone is shaded from light to dark grey, indicating how risky the informants perceive the grey zone to be. The findings may be useful when designing workplace health promotion programmes and alcohol regulations in the workplace.

Published: September 2019

Background Although the human papillomavirus (HPV) vaccine has been approved for use in adolescents in the US for over a decade, vaccination uptake remains low. Of concern, HPV vaccine coverage is below the national average in Minnesota, USA. To understand the reach of current HPV programming and research, we use an online media scan; this method may be applied to other jurisdictions to gain insight about various public health issues. Design and Methods This online media scan describes the nature and scope of ongoing activities to increase HPV vaccination in Minnesota. The media scan included: a) structured internet searches of HPV vaccine health education/promotion activities ongoing in Minnesota since 2013, and b) searches in research databases of the published literature on HPV vaccination in Minnesota from 2013 to 2018. Results Searches resulted in 880 online and 142 research article matches, with 40 and 36 meeting selection criteria. Results were categorized by activities focusing on race/ethnicity, sex, health providers, parents, lesbian, gay, bisexual, transgender and queer or questioning (LGBTQ) populations, geographic location, catchup vaccination, and insurance status. Most activities were statewide (52% health education/promotion and 35% research), followed by activities located in entirely urban areas (15% health education/promotion and 41% research) with only 6% of health education/promotion activities and 2% of research activities carried out in entirely rural areas. Conclusions A range of local and statewide HPV vaccine health education/promotion and research activities were identified in Minnesota. Several efforts partnered with American Indian and Somali/Somali-American communities, but fewer activities focused on HPV vaccination among LGBTQ youth and HPV vaccination in rural areas.
Sustainability and the Social Fabric
Authors: Padovani Clio , Whittaker Paul 
Published: September 2019

While the topic of sustainability in textile manufacture has been the subject of considerable research, much of this is limited to a focus on materials and practices and their ecological impact. Padovani and Whittaker offer a unique exploration of the textile industry in Europe from the perspective of social sustainability, shifting the focus from the materiality of textile production to the industry’s relationships with the communities from which the products originate.
Featuring six in-depth case studies from design entrepreneurs, artisans and textile businesses around Europe, from Harris Tweed in Scotland to luxury woollen mills in Italy, Sustainability and the Social Fabric explores how new centres of textile manufacturing have emerged from the economic decline in 2008, responding creatively and producing socially inclusive approaches to textile production. Case studies each represent a different approach to social sustainability and are supported by interviews with industry leaders and comparisons to the global textile industry. Demonstrating how some companies are rebuilding the local social fabric to encourage consumer participation through education, enterprise, health and wellbeing, the book suggests innovative business models that are economically successful and also, in turn, support wider societal issues.
Essential reading for students of textiles, fashion, design and related subjects, this book will demonstrate how a business ecosystem that focuses on inclusive growth and social innovation can lead to sustained mutual benefit for textile industries and their local communities.
Dichloroacetate ameliorates myocardial ischemia-reperfusion injury via regulating autophagy and glucose homeostasis
Authors: Li Shuo , Xie Boqia , Zhang Wenqian , Li Tong 
Published: September 2019

IntroductionAutophagy occurs in response to myocardial ischemia-reperfusion (I/R) injury and plays both a protective and detrimental role in this pathological process. Dichloroacetate (DCA) has a protective role during myocardial I/R injury, but its effects on autophagy induction are less well understood. We established a rat myocardial I/R injury model and investigated the effects of DCA on autophagy induction.Material and methodsHealthy Sprague-Dawley (SD) rats were used to establish a myocardial I/R model. The effect of DCA on cardiac infarct size, cardiac function, and serum levels of serum creatine kinase (CK), lactic dehydrogenase (LDH) and cardiac troponin I (cTnI) during I/R injury were assessed. Using cultured rat cardiac myocytes, we investigated the functional implications of DCA and explored the relevant mechanism(s) of DCA protection during I/R injury.ResultsDCA significantly decreases infarct size and arrhythmia scores, increases heart rate (HR), left ventricular developed pressure (LVDP), the maximal rate of pressure rise (+dp/dtmax) and coronary flow (CF), and reduces the levels of CK, LDH and cTnI after I/R. DCA treatment enhanced myocardial cell viability and alleviated apoptosis assessed through TUNEL assays and Bcl-2/Bax expression. Notably, the levels of the autophagy biomarkers Beclin-1, LC3II and reactive oxygen species (ROS) significantly decreased following DCA treatment. When Bcl-2 was silenced, Beclin-1 expression significantly decreased following DCA treatment, suggesting that DCA confers a protective role during I/R injury through autophagy regulation. Moreover, DCA was found to regulate glucose homeostasis through increasing the expression of Glut-1 and Glut-4.ConclusionsDCA contributes to I/R injury protection through the regulation of autophagy and glucose homeostasis.

Introducción: El damping-off, secadera o chupadera, es una enfermedad frecuente en los viveros forestales que ocasiona pérdidas económicas significativas a nivel mundial.
Objetivo: Evaluar la patogenicidad e incidencia de Fusarium circinatum Nirenberg & O´Donnell en plántulas de Pinus greggii Engelm. ex Parl., y el uso de Trichoderma harzianum Rifai como biocontrol en tres sustratos.
Materiales y métodos: El hongo fitopatógeno F. circinatum (cepa SF5) y el antagonista T. harzianum (cepa comercial T-22 KRL-AG2) se inocularon en P. greggii. Se utilizaron tres sustratos a base de turba de musgo, aserrín y corteza de pino. Se evaluaron la incidencia de la enfermedad y los índices morfológicos de la planta (diámetro del tallo, altura, relación peso seco aéreo/peso seco radical, índice de esbeltez e índice de calidad de Dickson). Los datos se sometieron a un análisis de varianza (procedimiento GLM de SAS versión 9.0) y comparación de medias de Tukey (P ≤ 0.05).
Resultados y discusión: La patogenicidad se comprobó mediante los postulados de Koch. La incidencia de la enfermedad fue alta (> 93 %) en los sustratos a base de turba de musgo y corteza de pino, y fue menor en el sustrato a base de aserrín (78 %). Trichoderma harzianum y el sustrato a base de aserrín redujeron la incidencia a 66 %. La calidad de la planta, con base en los índices morfológicos, fue mayor en el sustrato de turba de musgo.
Conclusión: Fusarium circinatum es patogénico en P. greggii; el sustrato a base de aserrín y T. harzianum redujeron la incidencia de la enfermedad en las plántulas.

Introducción: Conservar los ecosistemas terrestres en buen estado es un desafío a nivel global. En México, la rehabilitación forestal es una práctica utilizada ampliamente para el logro de tal encomienda.
Objetivo: Analizar el efecto de la rehabilitación forestal sobre los parámetros de la avifauna (riqueza, abundancia y diversidad) y la estructura vegetal.
Materiales y métodos: El estudio se realizó en El Porvenir, Hidalgo, México, en áreas bajo rehabilitación forestal con Pinus greggii Engelm. ex Parl. con edades de 5(R5), 12(R12) y 14(R14) años, y en un bosque de Pinus cembroides Zucc. como sitio de referencia (SR). El muestreo se hizo mediante un diseño sistemático en cuadrícula. La presencia avifaunística se monitoreó bajo dos esquemas: recuento en punto con radio fijo y captura mediante redes de niebla con esfuerzo constante. La estructura arbórea se caracterizó mediante cuadrantes con punto centrado. Las diferencias entre condiciones se probaron con un análisis multivariado de permutación de varianza (PERMANOVA).
Resultados y discusión: El SR presentó la mayor riqueza de aves (34) y mostró diferencias significativas (P = 0.0003) con las condiciones de rehabilitación. La distribución de la abundancia en R5 y R14 se ajustó a un modelo geométrico, R12 al logarítmico y SR a normal-logarítmico, presentando diferencias significativas entre sí (P = 0.033). La diversidad avifaunística presentó diferencias entre condiciones (P = 0.005); la máxima semejanza fue entre R14 y SR. A mayor edad de rehabilitación forestal, la estructura vegetal y los parámetros avifaunísticos incrementaron.
Conclusión: Las áreas bajo rehabilitación forestal funcionan como reservorios para el mantenimiento y conservación de la avifauna en ambientes perturbados.
Impact of warming shelf waters on ice mélange and terminus retreat at a large SE Greenland glacier

Published: September 2019

Abstract. By the end of 2018 Kangerlussuaq Glacier in southeast Greenland had retreated further inland than at any time in the past 80 years and its terminus was approaching a region of retrograde bed slope from where further rapid retreat would have been inevitable. Here we show that the retreat occurred because the glacier failed to advance during the winters of 2016/17 and 2017/18 owing to a weakened proglacial mélange. This mixture of sea ice and icebergs is normally rigid enough to inhibit calving in winter, but for 2 consecutive years it repeatedly collapsed, allowing Kangerlussuaq Glacier to continue to calve all year round. The mélange break-ups followed the establishment of anomalously warm surface water on the continental shelf during 2016, which likely penetrated the fjord. As calving continued uninterrupted from summer 2016 to the end of 2018 the glacier accelerated by 35 % and thinned by 35 m. These observations demonstrate the importance of near-surface ocean temperatures in tidewater glacier stability and show that it is not only deep-ocean warming that can lead to glacier retreat. During winter 2019 a persistent mélange reformed and the glacier readvanced by 3.5 km.

Published: September 2019

O Programa O Homem e a Biosfera, promovido pela Organização das Nações Unidas para a Educação, a Ciência e a Cultura - UNESCO, tem como principal objetivo a criação de Reservas da Biosfera– RB em diferentes biomas. Apesar da importância (posição estratégica e biodiversidade), a Reserva da Biosfera do Cerrado ainda tem modesta divulgação na mídia/comunidade acadêmica e poucas Unidades de Conservação que promovam a preservação do bioma. Com a finalidade de contribuir com esta discussão, o presente trabalho visa apresentar uma análise multitemporal da Reserva da Biosfera do Cerrado, no que se refere à questão do uso e ocupação da terra, realizada por meio dos dados do programa MapBiomas, no período de 2001 a 2016. A análise mostrou que ao longo dos anos houve uma forte conversão das áreas naturais prejudicando o objetivo central das reservas – preservação da biodiversidade. No total, foram aproximadamente 15 mil km² de áreas convertidas para uso antrópico, 8 mil km² somente entre 2004 e 2008, apresentando taxa de variação de 14% neste período.

Avaliação da demanda hídrica por pivôs centrais e agroindústrias na Alta Bacia do Ribeirão Santo Inácio – Orizona/GO
Authors: Rodrigues Lorena De Castro , Bayer Maximiliano 
Published: September 2019

A atividade agrícola é a principal responsável pelo uso consuntivo da água seguida pela atividade industrial. O agrohidronegócio ganha espaço à medida que a demanda por alimentos no mundo aumenta. Essa realidade é presente na Alta Bacia do Ribeirão Santo Inácio, localizada no município de Orizona (GO), onde ocorre uma dependência mútua entre atividade agrícola irrigada e atividade industrial. Os mapas temáticos deste estudo auxiliam a compreender a dinâmica da microbacia apresentando as características físicas do ambiente como a predominância de latossolos e baixa declividade do relevo nas proximidades dos cursos d’água, o que propicia a intensa atividade agrícola irrigada por pivô central. A projeção do total de água captada pelos pivôs centrais foi realizada a partir do cálculo de subtração da precipitação e a evapotranspiração da cultura plantada multiplicado pelo tamanho da área de cada pivô central. Conclui-se que se que nos meses do período de estiagem o déficit hídrico chega a 1.092 metros cúbicos por hora, implicando no consumo hídrico das agroindústrias que captam água a jusante do Ribeirão Santo Inácio.

Decolonial Feminism at the Intersection: A Critical Reflection on the Relationship Between Decolonial Feminism and Intersectionality
Authors: Velez Emma D. 
Published: September 2019

ABSTRACTThis article offers a critical reading of María Lugones's engagement with intersectionality theory, as primarily developed by Black feminists. I argue that her “linguistic critique” of intersectionality risks jeopardizing the possibility of coalitional politics emphasized by decolonial feminisms, especially between Black women and Latinas. We should instead attend to her “coloniality critique” that shows what undergirds the categorial logics intersectionality names, interrogating their source as a colonial imposition. By furthering the insights of intersectionality, I argue that decolonial feminism helps us to reorient our practices of resistance to categorial logics and the possibility of forging decolonizing coalitions among women of color.
