Abstract
We search for high-redshift dropout galaxies behind the Hubble Frontier Fields (HFF) galaxy cluster MACS J1149.5+2223, a powerful cosmic lens that has revealed a number of unique objects in its field. Using the deep images from the Hubble and Spitzer space telescopes, we find 11 galaxies at z > 7 in the MACS J1149.5+2223 cluster field, and 11 in its parallel field. The high-redshift nature of the bright z ≃ 9.6 galaxy MACS1149-JD, previously reported by Zheng et al., is further supported by non-detection in the extremely deep optical images from the HFF campaign. With the new photometry, the best photometric redshift solution for MACS1149-JD reduces slightly to z = 9.44 ± 0.12. The young galaxy has an estimated stellar mass of

Abstract
We present the discovery of two extended ∼0.12 mag dimming events of the weak-lined T Tauri star V1334. The start of the first event was missed but came to an end in late 2003, and the second began in 2009 February, and continues as of 2016 November. Since the egress of the current event has not yet been observed, it suggests a period of >13 years if this event is periodic. Spectroscopic observations suggest the presence of a small inner disk, although the spectral energy distribution shows no infrared excess. We explore the possibility that the dimming events are caused by an orbiting body (e.g., a disk warp or dust trap), enhanced disk winds, hydrodynamical fluctuations of the inner disk, or a significant increase in the magnetic field flux at the surface of the star. We also find a ∼0.32 day periodic photometric signal that persists throughout the 2009 dimming which appears to not be due to ellipsoidal variations from a close stellar companion. High-precision photometric observations of V1334 Tau during K2 campaign 13, combined with simultaneous photometric and spectroscopic observations from the ground, will provide crucial information about the photometric variability and its origin.
Observational Signatures of Transverse Magnetohydrodynamic Waves and Associated Dynamic Instabilities in Coronal Flux Tubes
Authors: Antolin P. , Moortel I. De , Doorsselaere T. Van , Yokoyama T. 
Published: February 2017

Abstract
Magnetohydrodynamic (MHD) waves permeate the solar atmosphere and constitute potential coronal heating agents. Yet, the waves detected so far may be but a small subset of the true existing wave power. Detection is limited by instrumental constraints but also by wave processes that localize the wave power in undetectable spatial scales. In this study, we conduct 3D MHD simulations and forward modeling of standing transverse MHD waves in coronal loops with uniform and non-uniform temperature variation in the perpendicular cross-section. The observed signatures are largely dominated by the combination of the Kelvin–Helmholtz instability (KHI), resonant absorption, and phase mixing. In the presence of a cross-loop temperature gradient, we find that emission lines sensitive to the loop core catch different signatures compared to those that are more sensitive to the loop boundary and the surrounding corona, leading to an out-of-phase intensity and Doppler velocity modulation produced by KHI mixing. In all of the considered models, common signatures include an intensity and loop width modulation at half the kink period, a fine strand-like structure, a characteristic arrow-shaped structure in the Doppler maps, and overall line broadening in time but particularly at the loop edges. For our model, most of these features can be captured with a spatial resolution of 0.″33 and a spectral resolution of 25 km s−1, although we do obtain severe over-estimation of the line width. Resonant absorption leads to a significant decrease of the observed kinetic energy from Doppler motions over time, which is not recovered by a corresponding increase in the line width from phase mixing and KHI motions. We estimate this hidden wave energy to be a factor of 5–10 of the observed value.
11. L’économie sociale et solidaire : le renouveau d’un idéal ?
Authors: Tovar Élisabeth 
Published: February 2017

L’économie sociale et solidaire, au lieu de rechercher la maximisation du profit, se fonde sur l’humain, son épanouissement et son bien-être. Son histoire que l’on peut faire remonter au début xix e siècle trouve son origine dans la rupture avec le capitalisme industriel sauvage. Elle a depuis acquis en importance, en diversité et en dynamisme toujours au service de l’humain, sous des formes variées. L’emploi au sein des entreprises de l’ESS est cependant plus faiblement rémunéré et plus précaire que les emplois des entreprises concurrentielles mais avec une plus forte satisfaction au travail. L’ESS est aujourd’hui traversée par un mouvement de normalisation marchande, parfois asphyxiée par ses compromis avec l’État et le marché. Enfin la conjonction des crises multiples qui frappent l’Europe conduit aujourd’hui l’économie vers un renouveau entrepreneurial solidaire et social.
Tanaquil et les chemises noires et brunes
Authors: Haack Marie-Laurence 
Published: February 2017

L’article traite de la réception de la figure antique de Tanaquil, donc des femmes étrusques, à l’époque du fascisme et du nazisme auprès de non-spécialistes de l’étruscologie. Il montre que les analyses de la figure antique de Tanaquil par J.J. Bachofen ont connu dans l’Italie et dans l’Allemagne des années 30 un véritable regain d’intérêt encouragé par la publication simultanée, en 1926, de deux anthologies de ses œuvres. A. Rosenberg et J. Evola interprètent tous deux Tanaquil en un sens raciste  : pour A. Rosenberg, Tanaquil incarne la menace de la dépravation orientale et J. Evola montre les efforts qu’a dû déployer le monde romain pour éliminer cette composante préromaine, orientale et gynécocrate.
Le Cardinal Capella de Henry de Montherlant. Fragments d’un récit inachevé
Authors: Duroisin Pierre 
Published: February 2017

Comme le manuscrit de Jules César qui fut présenté dans le n° 18 d’Anabases, celui du Cardinal Capella appartient au fonds Montherlant de la Bibliothèque nationale de France. Mais là s’arrête la ressemblance : Jules César est un dialogue datant de 1921 qui fut mené à son terme, alors que Le Cardinal Capella est un récit des années 1929-1930 et inachevé. Par ailleurs, le personnage de Jules César est partout dans l’œuvre de Montherlant, alors que Capella n’y est nulle part cité. Le sujet enfin est différent : la dimension politique qu’on avait dans le dialogue de 1921 est totalement absente du récit de 29-30. Capella est un prélat athée de la Renaissance italienne (il y a en cet Espagnol quelque chose des Borgia) dont le premier souci est la quête du plaisir, mais qui vit dans la peur, peur d’être démasqué, d’être trahi, d’être égorgé. L’expédition nocturne où l’a lancé son créateur fait un peu penser à celles que Suétone impute à Néron, ou à Caligula, mais le personnage est plus complexe qu’il n’y paraît, et s’il annonce par certains côtés le Costals des Jeunes Filles, le Guiscart de La Rose de sable ou le Don Juan de La Mort qui fait le trottoir, il est aussi parent, pour de plus hautes raisons, de l’abbé de Pradts de La Ville dont le prince est un enfant et des Garçons, voire du Celestino du Chaos et la nuit.
Observations d’un « profane » sur une réception singulière, celle de Weber « historien » de l’Antiquité
Authors: Chazel François 
Published: February 2017

Après une période de purgatoire qui s’étend jusqu’aux années 60, les travaux de Weber relatifs à l’Antiquité ont acquis une réelle reconnaissance scientifique, en particulier sous l’influence d’A. Momigliano et de M. Finley. Cependant, cette réception n’a pas été exempte d’ambiguïtés et a abouti même à certaines formes de méconnaissance. La première ambiguïté tient à la rareté des commentaires de Finley sur l’apport propre de Weber. La seconde est liée à son interprétation biaisée sur quelques points majeurs  : Finley s’est plus intéressé à la typologie économique de la ville qu’aux idéaltypes contrastés de politique économique urbaine construits par Weber dans le cadre d’une comparaison entre ville médiévale et cité antique  ; la logique de l’idéaltype paraît lui avoir largement échappé. Enfin, l’œuvre de Weber a été si étroitement associée à l’approche de Finley qu’elle est devenue tributaire d’abord de son succès puis de son rejet plus ou moins radical. Comme l’a montré Christian Meier, Weber ne se laisse pas enfermer dans le vieux débat entre primitivisme et modernisme  ; sa méthode d’étude, centrée sur la mise en évidence de la spécificité du monde antique et le jeu des interdépendances entre les phénomènes qui la produit, conserve sa fécondité heuristique. C’est dans cet esprit qu’il convient d’approfondir la réception de Weber selon des voies multiples, brièvement évoquées en conclusion.
Stromal Cell Niches in the Inflamed Central Nervous System

Published: February 2017

AbstractInflammation in the CNS must be tightly regulated to respond efficiently to infection with neurotropic pathogens. Access of immune cells to the CNS and their positioning within the tissue are controlled by stromal cells that construct the barriers of the CNS. Although the role of the endothelium in regulating the passage of leukocytes and small molecules into the CNS has been studied extensively, the contribution of fibroblastic stromal cells as portals of entry into the CNS was only recently uncovered. We review the critical immune-stimulating role of meningeal fibroblasts in promoting recruitment and retention of lymphocytes during CNS inflammation. Activated meningeal fibroblastic stromal cells have the capacity to rapidly elaborate an immune-competent niche that sustains protective immune cells entering the CNS from the draining cervical lymph node. Such stromal cell niches can ultimately foster the establishment of tertiary lymphoid tissues during chronic neuroinflammatory conditions.
Analysis of biological and meteorological controls of evapotranspiration in pristine forests and a pasture site in Amazonia

Published: February 2017

This work studied the behavior and seasonality of evapotranspiration influenced by biotic and abiotic factors through analysis of diurnal variation of aerodynamic resistance (ra), stomatal resistance (rs) and decoupling factor (Ω). This index was proposed by Jarvis and McNaughton (1986) as an indicative of the control of these resistances on the evapotranspiration of vegetation. Selection of representative data from wet and dry seasons from a primary forest in Central Amazonia and a primary forest and a pasture sites in Southwestern Amazonia had shown that: (i) ra is about 20 s.m-1 in both forests in both seasons, and ranges from 70 to 100 s.m-1 in the pasture site; (ii) rs varies both throughout the day and seasonally, with medians increasing from 40 in the morning, to 150 s.m-1 in late afternoon, in the wet season in the forests and from 50 to 160 s.m-1 in the pasture. These values increase in the dry season, with the forests rs ranging from 50 up to 500 s.m-1 and pasture rs starting from 140 s.m‑1 and reaching up to more than 1800 s.m-1 in the dry afternoons; (iii) Ω ranges from 0.5 to 0.8 during the wet season, and reduces to values below 0.5 in the afternoons during the dry season, indicating that, although a strong influence of net radiation in the evaporative loss is present, to a large extent the evapotranspiration fluxes are coupled to the biotic control of stomatal closure in the vegetation, especially in the pasture and during dry periods.

Sheep husbandry is considered an important economic practice in Brazil. However, there are problems associated with this practice. Haemonchosis stands out among these, and is known among sheep farmers for being a difficult disease to treat. Haemonchus contortus is considered the main helminth parasite of sheep, due to the fact that it is the only direct blood-sucking parasite, which can cause anemia, weight loss, submandibular swelling (mumps), low quality of meat and wool, and death of a large percentage of the herd. Currently, the predominant treatment is allopathic medicines, but resistance is increasing due to their repetitive use. In this sense, herbal medicine has emerged as a promising alternative. This study therefore aimed to evaluate the in vivo anti-parasitic activity of three plant extracts: hydroalcoholic extracts obtained by the percolation of Lepidium didymum and Momordica charantia and aqueous extract of Tagetes minuta. Animals of the Santa Inês breed were screened to identify parasitized specimens and separated into four groups of six animals each. One was used as an untreated control group, and the others were treated with 200 mg/day (5 mg/kg body weight) of the three extracts for 5 days. After treatment, EPG (eggs per gram of feces) was determined by the Mac Master method with modification. The animals in the groups treated with extracts of L. didymum and M. charantia showed a significant reduction (p <0.05) of EPG. These extracts may therefore be useful in the treatment of sheep haemonchosis.

Published: February 2017

This study evaluates the application of a polymeric microfiltration membrane in a gravitational filtration module and its combination with granular activated carbon (GAC) impregnated with copper, resulting in a hybrid process. The proposed system would be used to improve the quality of water for human consumption in developing countries. Permeate flux, pH, Escherichia coli removal, color, turbidity and free chlorine removals were evaluated in the applied process. Instrumental techniques, such as N2 adsorption at 77 K, scanning electron microscopy (SEM), transmission electron microscopy (TEM) and energy dispersive X-ray spectroscopy (EDX) analyses were used to characterize the proposed membrane and adsorbent. The GAC ensured higher chlorine removals, as well as higher permeate flux. Furthermore, the GAC impregnated with copper oxide nanoparticles exhibited higher Escherichia coli removal. Therefore, the hybrid gravitational membrane system applying GAC impregnated with copper oxide could be considered as a potential alternative point-of-use treatment to improve the quality of water for human consumption.

El uso de Internet por parte de las personas mayores para realizar gestiones con la Administración pública y las empresas no ha sido suficientemente estudiado. Los datos del censo publicados por el INE en julio de 2015 confirman el envejecimiento poblacional en España así como el escaso uso del grupo social de mayor edad de la Administración electrónica. El objetivo de este trabajo es profundizar en las razones del empleo limitado de la Administración electrónica y los trámites online por parte de los mayores internautas. Metodología: Se estudian las motivaciones y frenos en la utilización de tales trámites, según un riguroso análisis de la bibliografía científica publicada así como de las diversas encuestas realizadas sobre la cuestión por instituciones públicas y privadas. Resultados y Conclusiones: Los resultados muestran una aceptación del empleo de los recursos electrónicos para las tareas más rutinarias y sencillas debido a la rapidez y comodidad que proporcionan, al tiempo que fomentan la autonomía y el empoderamiento de las personas mayores. Si bien, se plantean una serie de aspectos que condicionan negativamente su utilización, sobre los que se debe incidir para favorecer una mayor inclusión digital de este grupo poblacional y que son abordados en la discusión de esta propuesta.

Abstract. The intercontinental transport of aerosols from the Sahara desert plays a significant role in nutrient cycles in the Amazon rainforest, since it carries many types of minerals to these otherwise low-fertility lands. Iron is one of the micronutrients essential for plant growth, and its long-range transport might be an important source for the iron-limited Amazon rainforest. This study assesses the bioavailability of iron Fe(II) and Fe(III) in the particulate matter over the Amazon forest, which was transported from the Sahara desert (for the sake of our discussion, this term also includes the Sahel region). The sampling campaign was carried out above and below the forest canopy at the ATTO site (Amazon Tall Tower Observatory), a near-pristine area in the central Amazon Basin, from March to April 2015. Measurements reached peak concentrations for soluble Fe(III) (48 ng m−3), Fe(II) (16 ng m−3), Na (470 ng m−3), Ca (194 ng m−3), K (65 ng m−3), and Mg (89 ng m−3) during a time period of dust transport from the Sahara, as confirmed by ground-based and satellite remote sensing data and air mass backward trajectories. Dust sampled above the Amazon canopy included primary biological aerosols and other coarse particles up to 12 µm in diameter. Atmospheric transport of weathered Saharan dust, followed by surface deposition, resulted in substantial iron bioavailability across the rainforest canopy. The seasonal deposition of dust, rich in soluble iron, and other minerals is likely to assist both bacteria and fungi within the topsoil and on canopy surfaces, and especially benefit highly bioabsorbent species. In this scenario, Saharan dust can provide essential macronutrients and micronutrients to plant roots, and also directly to plant leaves. The influence of this input on the ecology of the forest canopy and topsoil is discussed, and we argue that this influence would likely be different from that of nutrients from the weathered Amazon bedrock, which otherwise provides the main source of soluble mineral nutrients.
Systematic shifts in Budyko relationships caused by groundwater storage changes
Authors: Condon Laura E. , Maxwell Reed M. 
Published: February 2017

Abstract. Traditional Budyko analysis is predicated on the assumption that the watershed of interest is in dynamic equilibrium over the period of study, and thus surface water partitioning will not be influenced by changes in storage. However, previous work has demonstrated that groundwater–surface water interactions will shift Budyko relationships. While modified Budyko approaches have been proposed to account for storage changes, given the limited ability to quantify groundwater fluxes and storage across spatial scales, additional research is needed to understand the implications of these approximations. This study evaluates the impact of storage changes on Budyko relationships given three common approaches to estimating evapotranspiration fractions: (1) determining evapotranspiration from observations, (2) calculating evapotranspiration from precipitation and surface water outflow, and (3) adjusting precipitation to account for storage changes. We show conceptually that groundwater storage changes will shift the Budyko relationship differently depending on the way evapotranspiration is estimated. A 1-year transient simulation is used to mimic all three approaches within a numerical framework in which groundwater–surface water exchanges are prevalent and can be fully quantified. The model domain spans the majority of the continental US and encompasses 25 000 nested watersheds ranging in size from 100 km2 to over 3 000 000 km2. Model results illustrate that storage changes can generate different spatial patterns in Budyko relationships depending on the approach used. This shows the potential for systematic bias when comparing studies that use different approaches to estimating evapotranspiration. Comparisons between watersheds are also relevant for studies that seek to characterize variability in the Budyko space using other watershed characteristics. Our results demonstrate that within large complex domains the correlation between storage changes and other relevant watershed properties, such as aridity, makes it difficult to easily isolate storage changes as an independent predictor of behavior. However, we suggest that, using the conceptual models presented here, comparative studies could still easily evaluate a range of spatially heterogeneous storage changes by perturbing individual points to better incorporate uncertain storage changes into analysis.
