THE EFFECT OF MICROFRACTURING IN GABBRO-DOLERITES ON THEIR PHYSICAL PROPERTIES
Authors: Shekov Vitali , Myasnikova O. 
Published: October 2019

Simple and cheap methods for the study of building stone deposits for the production of blocks of commercial size can be used to make geological work more efficient. However, physical processes in a massif are hard to understand when doing geophysical research, and the effect of microstructural parameters, mainly the microfracturing of rocks, on geophysical field indices is poorly understood.
The authors have studied the impact of microfracturing on the physico-mechanical properties on coarse- to giant-grained rapakivi granites from the Salmi massif, Fennoscandian Shield. The goal of the present study is to assess the physical and physico-mechanical parameters in fine- and medium-grained quartz-free rocks.
The authors have studied the various physical and physico-mechanical indices of gabbro-dolerites from the Ropruchei sill (Fennoscandian Shield, within the deposit prospected and revealed the effect of microfracturing indices on them.
The study of these properties have shown that microfracturing in gabbro-dolerites is an essential factor which forms the physical parameters of a rock. The testing of this rock type has shown the rate of travel of an elastic wave is clearly related to the microfracturing of samples.
The magnetic properties of gabbro-dolerite are due to high concentrations of titanomagnetite, the mineral grains of which formed upon the crystallization of magma during its interstratal intrusion. The distribution of titanomagnetite, based on size and concentration in the rock, depends on liquation conditions in the active stress field. The dependence of the microfracturing of gabbro-dolerites on their iron concentration (FeO+Fe2O3) shows that these «damages» appeared at a ‘brittle” stage in the evolution of the massif in the form of microfractures, the structural parameters of which have inherited the parameters of the stress and deformation field which existed in the massif at that time and which accumulated iron.
As a result, microfracturing has a considerable effect on the parameters of the electromagnetic indices of the massif by accumulating iron oxides in the pores, and the higher the index, the higher the geophysical medium indices.
Understanding of the physical problem, which accompanies the formation of a gabbro-dolerite complex, helps conduct the geophysical study of a massif, interpret data more objectively and more accurately delineate massive zones in the medium that could be used as high-quality building materials.

Abstract
A longstanding problem in astrochemistry is the inability of many current models to account for missing sulfur content. Many relatively simple species that may be good candidates to sequester sulfur have not been measured experimentally at the high spectral resolution necessary to enable radioastronomical identification. On the basis of new laboratory data, we report searches for the rotational lines in the microwave, millimeter, and submillimeter regions of the sulfur-containing hydrocarbon HCCSH. This simple species would appear to be a promising candidate for detection in space owing to the large dipole moment along its b-inertial axis, and because the bimolecular reaction between two highly abundant astronomical fragments (CCH and SH radicals) may be rapid. An inspection of multiple line surveys from the centimeter to the far-infrared toward a range of sources from dark clouds to high-mass star-forming regions, however, resulted in nondetections. An analogous search for the lowest-energy isomer,

, is presented for comparison, and also resulted in nondetections. Typical upper limits on the abundance of both species relative to hydrogen are 10−9–10−10. We thus conclude that neither isomer is a major reservoir of interstellar sulfur in the range of environments studied. Both species may still be viable candidates for detection in other environments or at higher frequencies, providing laboratory frequencies are available.
Valeur(s) & management
Authors: Jehanin Laurent 
Published: October 2019

La relativité du concept de valeur permet de l’utiliser pour les achats de tous les types d’organisation, avec des métriques qui leur sont propres. Lorsqu’il s’agit de l’entreprise, les achats créent de la valeur pour l’entreprise directement en réduisant les coûts, en réduisant la consommation de liquidités, en réduisant le niveau de risque… Mais les achats créent également de la valeur de manière contributive : par la gestion de l’innovation des fournisseurs avec l’effet d’accroître les ventes ou de réduire les coûts, par le soutien des ventes dans un territoire, etc. Par ailleurs, la création de valeur financière par les achats peut se manifester, outre la variation d’un flux, comme le résultat ou le cash-flow, par l’accroissement d’un actif, comme la base fournisseurs, dont la valorisation fait aujourd’hui défaut. Enfin, les achats créent de la valeur pour les parties prenantes de l’entreprise : fournisseurs, clients, salariés, citoyens, territoire, société en général…, ce qui peut ouvrir un potentiel encore plus considérable que les économies à court terme, sans négliger ces dernières.
Séparer ou unir ? L’ambivalence de la diversité dans les espaces nocturnes de Beyrouth
Authors: Bonte Marie 
Published: October 2019

Reposant sur une enquête qualitative menée entre 2013 et 2016, cet article analyse les espaces de la vie nocturne de Beyrouth au prisme de la différence. À travers la notion de canopée cosmopolite (Anderson 2004), l’article montre comment les établissements que sont les bars et les clubs ainsi que les pratiques et les sociabilités qui s’y rattachent permettent un effacement temporaire des lignes de divisions (confessionnelles, socio-économiques, ethniques, de même que celles liées au genre ou à l’orientation sexuelle) tout en produisant des formes d’entre-soi économique et culturel. Cette dialectique de la canopée nocturne est chevillée aux problématiques de la ville post-conflit. Les espaces nocturnes constituent d’abord une forme d’appropriation de la ville sur un mode festif, ainsi qu’une manière de reconquérir la ville au-delà des divisions imposées par la guerre civile (1975-1990). En fonction des critères observés, la différence constitue par ailleurs un attribut ou un potentiel des lieux nocturnes : elle est expérimentée autant qu’elle est revendiquée. Ce sont donc les discours des noctambules et la mise en scène d’une « ville pacifiée » à travers ses nuits qui seront enfin analysés, afin de montrer que les rapprochements permis par la nuit créent d’autres processus de distinction et de domination.
Le parkour, une pratique au service de la participation juvénile en ville ? Dissidence récréative et affirmation des jeunes à Rennes et à Nantes
Authors: Lesné Robin 
Published: October 2019

Le parkour est un ludo-sport investissant les espaces ouverts et cumulant une double différentiation de la société urbaine par ses dimensions subversive et juvénile. Engageant une expérience alternative de l’espace, il invite au renouvellement du rapport à la ville d’un point de vue spatial, par le dépassement de sa division fonctionnelle et la réintroduction de la récréativité, mais également social, les pratiquants revendiquant une place dans le système décisionnel et une démocratie davantage participative. L’analyse du traitement institutionnel de cette pratique démontre que les projets d’aménagement peuvent constituer des outils de ce renouvellement. En mobilisant le concept de dissidence récréative, la déviance devient un élément positif au sein de la diversité urbaine. Ainsi, le parkour contribuerait à l’émergence d’une participation citoyenne renouvelée propre aux jeunes.
Analyse socio-institutionnelle de l’Office parlementaire d’évaluation des choix scientifiques et technologiques (OPECST)
Authors: Delvenne Pierre 
Published: October 2019

Il existe en Europe une diversité de modèles, d’approches et de pratiques de Technology Assessment (TA). De nombreux travaux ont déjà permis de catégoriser les organisations existantes en Europe. Pour appréhender d’une manière commune cette variété de TA on se réfère à deux dimensions principales : l’institutionnalisation par rapport au Parlement et le type de missions et de méthodologies poursuivies par le TA. Enzing (2012), Hennen & Ladikas (2009), Cruz et Sanz (2005) distinguent trois modèles : la « Commission parlementaire » (France, Grèce, Italie, Finlande), le « bureau parlementaire » (Suède, Allemagne, Royaume-Uni, Catalogne Parlement européen) et le modèle de « TA indépendant » (Suisse, Pays-Bas, Danemark, Norvège, Autriche) appelé aussi « modèle interactif ».

As opções de ações a funcionários que têm como vantagem a possibilidade do colaborador participar na valorização futura da empresa estão no cerne de crises financeiras e escândalos corporativos relacionados, principalmente, à manipulação de demonstrações contábeis. Diante dos novos dispositivos como os da Lei Sarbanes-Oxley (2002) e de Basiléia III (2010) emergem entre outros objetivos garantir maior transparência na gestão de empresas. Nesse sentido, o presente estudo buscou avaliar o nível de disclosure das instituições financeiras pós-crise financeira de 2008 dos programas de pagamento a funcionários. A amostra foi composta pelos principais bancos de 33 países, os denominados “grandes de demais para quebrar” que são mais propensos a absorver recursos públicos como forma de evitar sua falência, totalizando uma amostra total de 172 instituições. A qualidade das informações foi medida pela soma unitária de itens presentes ou não nas demonstrações financeiras, buscou-se estabelecer uma classificação para se pontuar países e instituições individualmente quanto às práticas de divulgação por meio de um conjunto de informações qualitativas e quantitativas que estavam nas notas explicativas. Os resultados indicam que o nível disclosure é influenciado pelo grupo cultural abordado conforme de modelo de Gray (1988), com o destaque do grupo cultural anglo-saxônico pela qualidade das informações e a uniformidade dos resultados. Observou-se que a aderência a esses programas de remuneração é influenciada pelo tamanho da economia dos países, com exceção de países como Alemanha, México e a Índia.
Evaluating possible intraspecific variation in resistance of western hemlock (Pinaceae) toAdelges tsugae(Hemiptera: Adelgidae)
Authors: Rose Alexander , Ross Darrell W. , Wallin Kimberly F. 
Published: October 2019

AbstractWestern hemlock,Tsuga heterophylla(Rafinesque) Sargent (Pinaceae), trees growing in a clonal, commercial seed orchard on Whidbey Island, Washington, United States of America were assessed forAdelges tsugae(Annand) (Hemiptera: Adelgidae) infestation levels to determine whether there was any evidence of resistance to this herbivore. Join-count statistics revealed thatA. tsugaeinfested trees were not clumped, but instead were randomly distributed throughout the seed orchard. Chi-square analyses suggested that there is a genetic basis for different levels ofA. tsugaeinfestation among the genets represented in the orchard. However, since none of the genets were completely free ofA. tsugaeinfestation, differences among genets seem to be related more to susceptibility or tolerance than complete resistance. Among the 17 genets that had five or more ramets in the seed orchard, only one had more than one ramet free ofA. tsugae. That genet had four of five ramets that were free ofA. tsugae. However, it is not possible to say whether that was due to chance or inherent tree characteristics that make it less susceptible toA. tsugaeinfestation.

Published: October 2019

Abstract
Skin tissue resident memory T cells (TRM) provide superior protection to a second infection. In this study, we evaluated the use of topical CpG oligodeoxynucleotide (ODN) as adjuvant to generate skin TRM in mice. Topical or s.c. CpG ODN adjuvant administration at the time of a s.c. Ag injection led to an accumulation of CD103− CD8 T cells in the epidermis. However, only mice with CpG ODN administered topically had significant numbers of CD103+ Ag-specific CD8 T cells persisting in the local epidermal skin, enhanced circulating memory cells in the blood, and showed protection from intradermal challenge with melanoma cells. Generation of Ag-specific CD8 T cells was dependent on TLR9 expression on hematopoietic cells and partially dependent on receptor expression on stromal cells. Topical challenge of immunized mice at a distal site led to significant expansion of Ag-specific T cells in the blood and accumulation in the challenged skin. We demonstrate that local and systemic T cell memory can be generated with topical CpG ODN at the time of s.c. immunization, suggesting a new method of enhancing current vaccine formulations to generate tissue TRM.
IL-36γ Is a Key Regulator of Neutrophil Infiltration in the Vaginal Microenvironment and Limits Neuroinvasion in Genital HSV-2 Infection
Authors: Gardner Jameson K. , Swaims-Kohlmeier Alison , Herbst-Kralovetz Melissa M. 
Published: October 2019

Abstract
HSV-2 is a neurotropic virus that causes a persistent, lifelong infection that increases risk for other sexually transmitted infections. The vaginal epithelium is the first line of defense against HSV-2 and coordinates the immune response through the secretion of immune mediators, including the proinflammatory cytokine IL-36γ. Previously, we showed that IL-36γ treatment promoted transient polymorphonuclear cell infiltration to the vaginal cavity and protected against lethal HSV-2 challenge. In this report, we reveal that IL-36γ specifically induces transient neutrophil infiltration but does not impact monocyte and macrophage recruitment. Using IL-36γ−/− mice in a lethal HSV-2 challenge model, we show that neutrophil counts are significantly reduced at 1 and 2 d postinfection and that KC-mediated mature neutrophil recruitment is impaired in IL-36γ−/− mice. Additionally, IL-36γ−/− mice develop genital disease more rapidly, have significantly reduced survival time, and exhibit an increased incidence of hind limb paralysis that is linked to productive HSV-2 infection in the brain stem. IL-36γ−/− mice also exhibit a significant delay in clearance of the virus from the vaginal epithelium and a more rapid spread of HSV-2 to the spinal cord, bladder, and colon. We further show that the decreased survival time and increased virus spread observed in IL-36γ−/− mice are not neutrophil-dependent, suggesting that IL-36γ may function to limit HSV-2 spread in the nervous system. Ultimately, we demonstrate that IL-36γ is a key regulator of neutrophil recruitment in the vaginal microenvironment and may function to limit HSV-2 neuroinvasion.
Escaping a Neighborhood Along a Prescribed Sequence in Lie Groups and Banach Algebras
Authors: Badea Catalin , Devinck Vincent , Grivaux Sophie 
Published: October 2019

AbstractIt is shown that Jamison sequences, introduced in 2007 by Badea and Grivaux, arise naturally in the study of topological groups with no small subgroups, of Banach or normed algebra elements whose powers are close to identity along subsequences, and in characterizations of (self-adjoint) positive operators by the accretiveness of some of their powers. The common core of these results is a description of those sequences for which non-identity elements in Lie groups or normed algebras escape an arbitrary small neighborhood of the identity in a number of steps belonging to the given sequence. Several spectral characterizations of Jamison sequences are given, and other related results are proved.
Ideas and perspectives: Is dark carbon fixation relevant for oceanic primary production estimates?
Authors: Baltar Federico , Herndl Gerhard J. 
Published: October 2019

Abstract. About half of the global primary production (PP) is generated in
the euphotic layer of the ocean. The 14C method developed by
Steemann Nielsen (Nielsen, 1952) more than half a century
ago has been the most frequently used method to determine PP in all aquatic
systems. This method includes dark incubations to exclude the
non-phototrophic dissolved inorganic carbon (DIC) fixation. The presence of
significant dark DIC fixation rates has been habitually used to suggest the
inaccuracy of the 14C method to determine autotrophic phytoplankton
primary production. However, we suggest that the dark DIC fixation
rates should be incorporated into global oceanic carbon production estimates
since the total production of organic matter does not originate only from
photosynthesis but also from other processes such as chemoautotrophic and
anaplerotic processes. Here we analyzed data collected over almost 30 years
from the longest available oceanic time series and calculated that the
inclusion of dark DIC fixation would increase oceanic PP estimates by
5 %–22 % when total dark DIC fixation is included or by 2.5 %–11 % when only
considering the nighttime DIC fixation. We conclude that dark DIC fixation
should be included into global oceanic primary production estimates as it
represents newly synthesized organic carbon (ca. 1.2–11 Pg C yr−1)
available for the marine food web.
Temporally dependent effects of rainfall characteristics on inter- and intra-event branch-scale stemflow variability in two xerophytic shrubs

Published: October 2019

Abstract. Stemflow is important for recharging root-zone soil moisture in arid
regions. Previous studies have generally focused on stemflow volume,
efficiency and influential factors but have failed to depict stemflow
processes and quantify their relations with rainfall characteristics within
events, particularly for xerophytic shrubs. Here, we measured the stemflow
volume, intensity, funneling ratio and time lags to rain at two dominant
shrub species (Caragana korshinskii and Salix psammophila) and rainfall characteristics during 54 events at the
semiarid Liudaogou catchment of the Loess Plateau, China, during the
2014–2015 rainy seasons. The funneling ratio was calculated as the ratio
between stemflow and rainfall intensities at the inter- and intra-event scales.
Our results indicated that the stemflow of C. korshinskii and S. psammophila, on average, started at 66.2
and 54.8 min, maximized 109.4 and 120.5 min after rain began, and ended
20.0 and 13.5 min after rain ceased. The two shrubs had shorter stemflow
duration (3.8 and 3.4 h) and significantly larger stemflow intensities
(517.5 and 367.3 mm h−1) than those of rain (4.7 h and 4.5 mm h−1). As branch size increased, both species shared the
decreasing funneling ratios (97.7–163.7 and 44.2–212.0) and stemflow
intensities (333.8–716.2 and 197.2–738.7 mm h−1). Tested by the multiple correspondence analysis and
stepwise regression, rainfall amount and duration controlled stemflow volume
and duration, respectively, at the event scale by linear relations (p < 0.01). Rainfall intensity and raindrop momentum controlled stemflow
intensity and time lags to rain for both species within the event by linear or
power relationships (p < 0.01). Rainfall intensity was the key factor
affecting stemflow process of C. korshinskii, whereas raindrop momentum had the greatest
influence on stemflow process of S. psammophila. Therefore, rainfall characteristics had
temporally dependent influences on corresponding stemflow variables, and the
influence also depended on specific species.
Role of sublimation and riming in the precipitation distribution in the Kananaskis Valley, Alberta, Canada
Authors: Poirier Émilie , Thériault Julie M. , Leriche Maud 
Published: October 2019

Abstract. The phase of precipitation and its distribution at the surface can affect water resources and the regional water cycle of a region. A field project was held in March–April 2015 on the eastern slope of the Canadian Rockies to document precipitation characteristics and associated atmospheric conditions. During the project, 60 % of the particles documented were rimed in relatively warm and dry conditions. Rain–snow transitions also occurred aloft and at the surface in sub-saturated conditions. Ice-phase precipitation falling through a saturated atmospheric layer with temperatures > 0 ∘C will start melting. In contrast, if the melting layer is sub-saturated, the ice-phase precipitation undergoes sublimation, which increases the depth of the rain–snow transition. In this context, this study investigates the role of sublimation and riming in precipitation intensity and type reaching the surface in the Kananaskis Valley, Alberta, during March–April 2015. To address this, a set of numerical simulations of an event of mixed precipitation observed at the surface was conducted. This event on 31 March 2015 was documented with a set of devices at the main observation site (Kananaskis Emergency Services, KES), including a precipitation gauge, disdrometer, and micro rain radar. Sensitivity experiments were performed to assess the impacts of temperature changes from sublimation and the role of the production of graupel (riming) aloft in the surface precipitation evolution. A warmer environment associated with no temperature changes from sublimation leads to a peak in the intensity of graupel at the surface. When the formation of graupel is not considered, the maximum snowfall rate occurred at later times. Results suggest that unrimed snow reaching the surface is formed on the western flank and is advected eastward. In contrast, graupel would form aloft in the Kananaskis Valley. The cooling from sublimation and melting by rimed particles increases the vertical shear near KES. Overall, this study illustrated that the presence of graupel influenced the surface evolution of precipitation type in the valley due to the horizontal transport of precipitation particles.
