В соответствии с российскими нормами хранение аммиачной селитры, как правило, должно осуществляться в отдельностоящих одноэтажных складских зданиях не ниже II степени огнестойкости. При этом максимально допустимое количество хранимой селитры в пределах пожарного отсека не должно превышать 5000 т, в то время как в странах Прибалтики (Латвия, Эстония) допускается единовременное хранение 25 000 т и более. В работе предпринята попытка расчетно-аналитическим путем обосновать унификацию требований пожарной безопасности российских и зарубежных норм хранения аммиачной селитры.
The storage of ammonium nitrate usually should be realized in separate single-story warehouse structures of at least II degree of fire resistance in accordance with Russian standards. At the same time, the maximum allowable amount of stored ammonium nitrate within the fire compartment should not exceed 5000 tons, while the simultaneous storage of 25000 or more tons is allowed in the Baltic countries (Latvia, Estonia). Authors attempt to substantiate the unification of fire safety requirements for ammonium nitrate storage in Russian and foreign standards by calculation and analysis.
Hunt for Starspots in HARPS Spectra of G and K Stars
Authors: Morris Brett M. , Hoeijmakers H. Jens , Kitzmann Daniel , Demory Brice-Olivier 
Published: June 2020

Abstract
We present a method for detecting starspots on cool stars using the cross-correlation function (CCF) of high-resolution molecular spectral templates applied to archival high-resolution spectra of G and K stars observed with the High Accuracy Radial Velocity Planet Searcher (HARPS)/HARPS-N. We report nondetections of starspots on the Sun even when the Sun was spotted, the solar twin 18 Scorpii, and the very spotted Sun-like star HAT-P-11, suggesting that Sun-like starspot distributions will be invisible to the CCF technique, and should not produce molecular absorption signals that might be confused for signatures of exoplanet atmospheres. We detect strong TiO absorption in the T Tauri K-dwarfs LkCa 4 and AA Tau, consistent with significant coverage by cool regions. We show that despite the nondetections, the technique is sensitive to relatively small spot coverages on M dwarfs and large starspot areas on Sun-like stars.

Published: June 2020

Abstract
We present a study on the radial profiles of the D4000, luminosity-weighted stellar ages τ
L, and luminosity-weighted stellar metallicities [Z/H]L of 3654 nearby galaxies (0.01 < z < 0.15) using the IFU spectroscopic data from the MaNGA survey available in the SDSS DR15, in an effort to explore the connection between median stellar population radial gradients (i.e., ∇D4000, ∇τ
L, ∇[Z/H]L) out to ∼1.5 R

e
and various galaxy properties, including stellar mass (M
⋆), specific star formation rate (sSFR), morphologies, and local environment. We find that M
⋆ is the single most predictive physical property for ∇D4000 and ∇[Z/H]L. The most predictive properties for ∇τ
L are sSFR and, to a lesser degree, M
⋆. The environmental parameters, including local galaxy overdensities and central–satellite division, have virtually no correlation with stellar population radial profiles for the whole sample, but the ∇D4000 of star-forming satellite galaxies with M
⋆ ≲ 1010
M
⊙ exhibit a significant positive correlation with galaxy overdensities. Galaxies with lower sSFR have on average steeper negative stellar population gradients, and this sSFR dependence is stronger for more massive star-forming galaxies. The negative correlation between the median stellar population gradients and M
⋆ are best described largely as segmented relationships, whereby median gradients of galaxies with log M
⋆ ≲ 10.0 (with the exact value depending on sSFR) have much weaker mass dependence than galaxies with higher M
⋆. While the dependence of the radial gradients of ages and metallicities on T-Types and central stellar mass surface densities are generally not significant, galaxies with later T-Types or lower central mass densities tend to have significantly lower D4000, younger τ
L, and lower [Z/H]L across the radial ranges probed in this study.

Abstract
We present the discovery of WISEA J083011.95+283716.0, the first Y-dwarf candidate identified through the “Backyard Worlds: Planet 9” citizen science project. We identified this object as a red, fast-moving source with a faint W2 detection in multiepoch AllWISE and unWISE images. We have characterized this object with Spitzer and Hubble Space Telescope’s (HST) follow-up imaging. With mid-infrared detections in Spitzer's ch1 and ch2 bands and flux upper limits in HST F105W and F125W filters, we find that this object is both very faint and has extremely red colors (ch1 − ch2 = 3.25 ± 0.23 mag, F125W − ch2 ≥ 9.36 mag), consistent with a T
eff ∼ 300 K source, as estimated from the known Y-dwarf population. A preliminary parallax provides a distance of

pc, leading to a slightly warmer temperature of ∼350 K. The extreme faintness and red HST and Spitzer colors of this object suggest that it may be a link between the broader Y-dwarf population and the coldest known brown dwarf WISE J0855−0714, and may highlight our limited knowledge of the true spread of Y-dwarf colors. We also present four additional “Backyard Worlds: Planet 9” late-T brown dwarf discoveries within 30 pc.
Role of the Coronal Environment in the Formation of Four Shocks Observed without Coronal Mass Ejections at Earth’s Lagrangian Point L1

Published: June 2020

Abstract
The main goal of this study is to determine the solar origin of four single shocks observed at the Lagrange point L1 and followed by storm sudden commencements (SSCs) during 2002. We look for associated coronal mass ejections (CMEs), starting from estimates of the transit time from Sun to Earth. For each CME, we investigate its association with a radio type II burst, an indicator of the presence of a shock wave. For three of the events, the type II burst is shown to propagate along the same, or a similar, direction as the fastest segment of the CME leading edge. We analyze for each event the role of the coronal environment in the CME development, the shock formation, and their propagation, to finally identify its complex evolution. The ballistic velocity of these shocks during their propagation from the corona to L1 is compared to the shock velocity at L1. Based on a detailed analysis of the shock propagation and possible interactions up to 30 solar radii, we find a coherent velocity evolution for each event, in particular for one event, the 2002 April 14 SSC, for which a previous study did not find a satisfactory CME source. For the other three events, we observe the formation of a white-light shock overlying the different sources associated with those events. The localization of the event sources over the poles, together with an origin of the shocks being due to encounters of CMEs, can explain why at L1 we observe only single shocks and not interplanetary CMEs.

Published: June 2020

Abstract
We present 1.3 mm ALMA dust polarization observations at a resolution of ∼0.02 pc for three massive molecular clumps, MM1, MM4, and MM9, in the infrared dark cloud G28.34+0.06. With these sensitive and high-resolution continuum data, MM1 is resolved into a cluster of condensations. The magnetic field structure in each clump is revealed by the polarized emission. We found a trend of decreasing polarized emission fraction with increasing Stokes I intensities in MM1 and MM4. Using the angular dispersion function method (a modified Davis–Chandrasekhar–Fermi method), the plane-of-sky magnetic field strengths in two massive dense cores, MM1-Core1 and MM4-Core4, are estimated to be ∼1.6 mG and ∼0.32 mG, respectively. The virial parameters in MM1-Core1 and MM4-Core4 are calculated to be ∼0.76 and ∼0.37, respectively, suggesting that massive star formation does not start in equilibrium. Using the polarization-intensity gradient-local gravity method, we found that the local gravity is closely aligned with intensity gradient in the three clumps, and the magnetic field tends to be aligned with the local gravity in MM1 and MM4 except for regions near the emission peak, which suggests that the gravity plays a dominant role in regulating the gas collapse. Half of the outflows in MM4 and MM9 are found to be aligned within 10° of the condensation-scale (<0.05 pc) magnetic field, indicating that the magnetic field could play an important role from condensation to disk scale in the early stage of massive star formation.
Atrial fibrillation: Importance of real world data from regional registries. A focus on the BALKAN-AF registry

Published: June 2020

Real world registries of patients with atrial fi brillation (AF) have provided important evidence on contemporary AF management and adherence to guidelines in real-world patients across most of regions in Europe. While prospective randomized clinical trials are the ‘gold standard’ of evidence, we recognize that trials have specifi c inclusion/exclusion criteria and many groups of patients can be under-represented. Thus, real world evidence is needed to supplement and augment the evidence, especially for the under-represented patient groups (eg. the very elderly and frail, ethnic minorities, end stage renal failure, those in nursing homes, cognitive impairment, etc) that have been largely under-represented or excluded from clinical trials. The BALKAN-AF survey is the largest prospective, multicenter (a total of 49 centres), observational AF dataset from the Balkans, a European region inhabited by about 10% of the European population that has been under-represented in many prior clinical trials or registries. In BALKAN-AF, data regarding consecutive subjects with electrocardiographically documented non-valvular AF were collected in seven Balkan countries (Albania, Bosnia & Herzegovina, Bulgaria, Croatia, Montenegro, Romania and Serbia) by a cardiologist or an internal medicine specialist where cardiologist was not available. The Serbian Atrial Fibrillation Association created and conducted the BALKAN-AF survey (performed from December 2014 to February 2015).
Politiques familiales, emploi et représentations collectives : des différences Est/Ouest qui s’atténuent

Avant l’unification de l’Allemagne, les femmes à l’Est, qu’elles aient ou non des enfants à charge, travaillaient à plein temps, alors qu’à l’Ouest persistait le modèle du male breadwinner . Depuis la chute du Mur, les deux modèles ont changé, le premier brutalement, dans la foulée de l’écroulement de l’économie est-allemande, le second progressivement, suite aux adaptations de la politique familiale et à l’évolution des mentalités. Au cours de la dernière décennie, a-t-on observé une atténuation des différences entre les nouveaux et anciens Länder au regard du taux d’emploi et des modalités de participation au marché du travail des mères ? Et si oui, quelles en sont les raisons ?

Published: June 2020

La population riveraine de la Rivière Xingu a souffert tout type de violations des droits humains lors du processus d’installation de l’Usine hydroélectrique de Belo Monte, dans l’Amazonie brésilienne. Le changement radical de son mode de vie a constitué une condition d’extrême vulnérabilité sociale. Cet article prétend discuter la construction de la Clinique de Soin, un dispositif clinique d’attention à la souffrance psychique fondé sur l’écoute articulée à l’expérience territoriale. Il est méthodologiquement orienté par la psychanalyse et a impliqué une proposition d’attention et témoignage de façon présentielle auprès de la communauté atteinte. Nous avons l'intention de réfléchir au caractère aliénant de la suppléance identitaire présente sur le territoire comme une réponse possible face à la violence subie. Entre la négation de l’impossible retour à ce qui a été perdu (exprimé par la demande du discours de la lutte pour la restitution du passé) et l’impuissance (exprimée par le corps tombé malade qui immobilise le sujet), la psychanalyse offre une troisième voie de guérison. L’intervention a démontré que, dans la plupart des cas reçus, il y a eu un changement de position du côté du sujet. L’éthique de la psychanalyse, régulatrice de cette clinique, a trouvé sa place dans la fonction désir de l’analyste afin de soutenir, en tant que seul élément incontournable au « faire » de l’analyste, la réalisation d'un tel travail clinique.
Vers une approche développementale du design
Authors: Gourlet Pauline 
Published: June 2020

Quel(s) rôle(s) le design pourrait-il tenir face à la crise paradigmatique résumée dans la notion aujourd’hui largement mobilisée d’Anthropocène ? Plusieurs tentatives de redéfinition du champ émergent, et on assiste un peu partout à une mutation des objets, des pratiques et des postures des designers. Dans le contexte de cette mutation, cet article présente des concepts issus de la psychologie développementale et les prend comme point de départ pour proposer une approche développementale du design. Cette approche dessine un design au présent, émancipé de la notion de projet et de l’ambition d’amélioration de l’habitabilité du monde : elle vise à (re)configurer les formes de l’agir collectif et les relations entre les entités agissantes, au sein des situations. Il devient alors primordial d’outiller l’attention aux processus fins de transformation à l’œuvre et aux devenirs de chaque entité à partir des activités situées et des « dialogues-en-actes » qui s’y déroulent.

The mechanisms and seasonal differences of the impact of aerosols on daytime surface urban heat island effect

Abstract. The urban heat island intensity (UHII) is the temperature difference between
urban areas and their rural surroundings. It is commonly attributed to
changes in the underlying surface structure caused by urbanization. Air
pollution caused by aerosol particles can affect the UHII through changing
(1) the surface energy balance by the aerosol radiative effect (ARE) and (2) planetary-boundary-layer (PBL)
stability and airflow intensity by modifying thermodynamic structure, which
is referred to as the aerosol dynamic effect (ADE). By analyzing satellite data
and ground-based observations collected from 2001 to 2010 at 35 cities in
China and using the WRF-Chem model, we find that the impact of aerosols on
UHII differs considerably: reducing the UHII in summer but increasing the
UHII in winter. This seasonal contrast is proposed to be caused by the
different strengths of the ARE and ADE between summer and winter. In summer,
the ARE on UHII is dominant over the ADE, cooling down surface temperature
more strongly in urban areas than in rural areas because of much higher
aerosol loading, and offsets the urban heating, therefore weakening UHII. In
winter, however, the ADE is more dominant, because aerosols stabilize the
PBL more in the polluted condition, weakening the near-surface heat
transport over urban areas in both vertical and horizontal directions. This
means that the heat accumulated in urban areas is dispersed less effectively,
and thus the UHII is enhanced. These findings shed new light on the impact
of the interaction between urbanization-induced surface changes and air
pollution on urban climate.

Abstract. Southern Ocean (SO) shortwave (SW) radiation biases are a common problem in contemporary general circulation models (GCMs), with most models exhibiting a tendency to absorb too much incoming SW radiation. These biases have been attributed to deficiencies in the representation of clouds during the austral summer months, either due to cloud cover or cloud albedo being too low. The problem has been the focus of many studies, most of which utilised satellite datasets for model evaluation. We use multi-year ship-based observations and the CERES spaceborne radiation budget measurements to contrast cloud representation and SW radiation in the atmospheric component Global Atmosphere
(GA) version 7.1 of the HadGEM3 GCM and the MERRA-2 reanalysis. We find that
the prevailing bias is negative in GA7.1 and positive in MERRA-2. GA7.1
performs better than MERRA-2 in terms of absolute SW bias. Significant errors
of up to 21 W m−2 (GA7.1) and 39 W m−2 (MERRA-2) are present
in both models in the austral summer. Using ship-based ceilometer observations,
we find low cloud below 2 km to be predominant in the Ross Sea and the
Indian Ocean sectors of the SO. Utilising a novel surface lidar simulator
developed for this study, derived from an existing Cloud Feedback Model Intercomparison Project (CFMIP) Observation Simulator Package (COSP) – active remote sensing simulator (ACTSIM) spaceborne lidar
simulator, we find that GA7.1 and MERRA-2 both underestimate low cloud and fog
occurrence relative to the ship observations on average by 4 %–9 % (GA7.1) and
18 % (MERRA-2). Based on radiosonde observations, we also find the low cloud
to be strongly linked to boundary layer atmospheric stability and the sea
surface temperature. GA7.1 and MERRA-2 do not represent the observed
relationship between boundary layer stability and clouds well. We find that
MERRA-2 has a much greater proportion of cloud liquid water in the SO in
austral summer than GA7.1, a likely key contributor to the difference in the SW
radiation bias. Our results suggest that subgrid-scale processes (cloud and
boundary layer parameterisations) are responsible for the bias and that in
GA7.1 a major part of the SW radiation bias can be explained by cloud cover
underestimation, relative to underestimation of cloud albedo.
