Abstract. In this study the climatology of ionospheric scintillations and the zonal drift velocities of scintillation-producing irregularities are depicted for a station located under the southern crest of the equatorial ionization anomaly. Then, the α − μ ionospheric fading model is used for the first- and second-order statistical characterization of amplitude scintillations. In the statistical analyzes, data are used from single-frequency GPS receivers acquired during ∼ 17 years (September 1997–November 2014) at Cachoeira Paulista (22.4° S; 45.0° W), Brazil. The results reveal that the nocturnal occurrence of scintillations follows the seasonal distribution of plasma bubble irregularities observed in the longitudinal sector of eastern South America. In addition to the solar cycle dependence, the results suggest that the occurrence climatology of scintillations is also modulated by the secular variation in the dip latitude of Cachoeira Paulista, since the maximum occurrence of scintillations during the peak of solar cycle 24 was ∼ 20 % lower than that observed during the maximum of solar cycle 23. The dynamics of the irregularities throughout a solar cycle, as investigated from the estimates of the mean zonal drift velocities, presented a good correlation with the EUV and F10.7 cm solar fluxes. Meanwhile, the seasonal behavior showed that the magnitude of the zonal drift velocities is larger during the December solstice months than during the equinoxes. In terms of modeling, the results for the α − μ distribution fit quite well with the experimental data and with the temporal characteristics of fading events independently of the solar activity level.

Published: November 2017

Abstract. Carbonate geochemistry research in large estuarine systems is limited. More work is needed to understand how changes in land-use activity influence watershed export of organic and inorganic carbon, acids, and nutrients to the coastal ocean. To investigate the seasonal variation of the inorganic carbon system in the Delaware Estuary, one of the largest estuaries along the US east coast, dissolved inorganic carbon (DIC), total alkalinity (TA), and pH were measured along the estuary from June 2013 to April 2015. In addition, DIC, TA, and pH were periodically measured from March to October 2015 in the nontidal freshwater Delaware, Schuylkill, and Christina rivers over a range of discharge conditions. There were strong negative relationships between river TA and discharge, suggesting that changes in HCO3− concentrations reflect dilution of weathering products in the drainage basin. The ratio of DIC to TA, an understudied but important property, was high (1.11) during high discharge and low (0.94) during low discharge, reflecting additional DIC input in the form of carbon dioxide (CO2), most likely from terrestrial organic matter decomposition, rather than bicarbonate (HCO3−) inputs due to drainage basin weathering processes. This is also a result of CO2 loss to the atmosphere due to rapid water transit during the wet season. Our data further show that elevated DIC in the Schuylkill River is substantially different than that in the Delaware River. Thus, tributary contributions must be considered when attributing estuarine DIC sources to the internal carbon cycle versus external processes such as drainage basin mineralogy, weathering intensity, and discharge patterns. Long-term records in the Delaware and Schuylkill rivers indicate shifts toward higher alkalinity in estuarine waters over time, as has been found in other estuaries worldwide. Annual DIC input flux to the estuary and export flux to the coastal ocean are estimated to be 15.7 ± 8.2  ×  109 mol C yr−1 and 16.5 ± 10.6  ×  109 mol C yr−1, respectively, while net DIC production within the estuary including inputs from intertidal marshes is estimated to be 5.1  ×  109 mol C yr−1. The small difference between riverine input and export flux suggests that, in the case of the Delaware Estuary and perhaps other large coastal systems with long freshwater residence times, the majority of the DIC produced in the estuary by biological processes is exchanged with the atmosphere rather than exported to the sea.

Keuze voor een sanctiestelsel: bestuurlijke boete of bestuurlijke strafbeschikking?
Sinds de invoering van de bestuurlijke strafbeschikking zijn bepaalde voordelen van de bestuurlijke boete komen te vervallen. In deze bijdrage staat de vraag centraal wat anno 2017 de voordelen van de bestuurlijke boete zijn. Betoogd wordt dat bestuurlijkeboeterecht in materieel opzicht strafrecht is en in procedureel opzicht bestuursrecht, en dat de keuze voor de bestuurlijke boete daarom vooral op procedurele argumenten moet stoelen. Het belangrijkste procedurele argument ten gunste van de bestuurlijke boete is het vermijden van extra procedures. Het argument dat de bestuurlijke boete qua rechtsbescherming zou onderdoen voor de bestuurlijke strafbeschikking wordt van de hand gewezen.

Bespiegelingen over de keuze tussen bestuursrecht en strafrecht
In de nabije toekomst zal de wetgever zich gaan beraden over de zogenoemde ‘open context’ en ‘besloten context’. Deze criteria spelen een belangrijke rol ten aanzien van de keuze tussen het bestuursrecht en het strafrecht. Vanuit meerdere hoeken zijn deze criteria bekritiseerd, omdat ze te onbepaald zijn. In deze bijdrage wordt betoogd dat de wetgever meer gewicht moet toekennen aan het criterium van de ernstige gedraging. Er dient te worden gekozen voor het strafrecht indien sprake is van een ernstige gedraging, terwijl bestuursrechtelijk optreden mogelijk is bij minder ernstige gedragingen. Ten aanzien van de keuze tussen de bestuurlijke boete en de bestuurlijke strafbeschikking dient vooral pragmatisch te worden gekozen.

‘Een beetje wet kost drie dagen’: het bevriezingswetje eigen risico zorgverzekering en andere spoedwetten
Het wetje waarmee de hoogte van het eigen risico voor de zorgverzekering voor 2018 werd bevroren op € 385 (Stb. 2017, 356) kwam binnen drie dagen tot stand. De Tweede en Eerste Kamer behandelden het wetsvoorstel op dezelfde dag. In deze bijdrage wordt ingegaan op dit bijzondere wetgevingsproces. Onder meer wordt daarbij aandacht besteed aan de figuur van een mondeling eindverslag, waar de Eerste Kamer tegenwoordig anders mee omgaat dan voorheen. Ook wordt de vraag besproken waarom het wetje per se vóór 1 oktober in het Staatsblad moest staan. Op de ranglijst van de snelst tot stand gebrachte wetten ooit neemt het bevriezingswetje waarschijnlijk een (gedeelde) tweede plaats in. De eerste plaats wordt ingenomen door twee crisiswetten uit 1914. Ook die wetten uit 1914 behandelden de Tweede en Eerste Kamer op dezelfde dag. Dat gebeurde later nog een keer in 1938. Uit de parlementaire geschiedenis blijkt overigens dat die totstandbrenging van een wet in enkele weken geen unicum is. Vaak worden wetten die heel snel tot stand moeten komen, aangeduid als ‘spoedwet’ of ‘noodwet’. Aan het slot van de bijdrage wordt deze terminologie besproken.
Simulacres et reenactment : l’aura de Laura entre cinéma et télévision, de Preminger (Laura) à Lynch (Twin Peaks)
Authors: Vaillancourt Thibaut 
Published: November 2017

Dans quelle mesure les pratiques subsumées sous l’intraduisible notion de reenactment sont-elles susceptibles d’être rapportées à la notion de simulacre, à l’eidôlon, dont l’exclusion du champ de la connaissance a fondé avec Platon un nouvel ordre philosophique ? En passant par l’analyse d’une remise en jeu intermédiale de Laura d’Otto Preminger (1944) par David Lynch et Mark Frost dans la série Twin Peaks (1990-1991), il s’agit de montrer en quoi convergent deux relations : le rapport du refaire à l’oeuvre dite « originale » et l’opposition d’une ontologie du simulacre à l’épuration essentialiste du geste platonicien. En cela, l’aura de Laura suggère une observation selon laquelle les pratiques de reenactment rejouent, dans les domaines de l’art, le renversement de la hiérarchie platonicienne par la revalorisation du simulacre, telle qu’elle est apparue chez Nietzsche, Klossowski ou Deleuze.
Rejouer l’archive par l’animation : la performance du geste graphique comme appropriation mémorielle
Authors: Fevry Sébastien , Wouters Nicolas 
Published: November 2017

Cet article entend montrer en quoi le concept de reenactement permet d’éclairer certaines pratiques mémorielles du documentaire animé, sachant que nous nous focalisons ici sur la performance du geste graphique à l’oeuvre dans ce type de cinéma. Plus précisément, notre propos sera d’examiner les relations entre le geste graphique et les archives visuelles (films, photographies…). Sous cet éclairage, il apparaîtra que le geste graphique répond essentiellement à deux fonctions : une fonction d’approfondissement, qui consiste à explorer les contours d’une archive donnée comme pour en approfondir la résonance mémorielle, et une fonction relationnelle, visant à réassembler, par le biais de plans composites, des archives de différents statuts participant à la construction d’une même histoire personnelle. Dans les deux cas, le geste graphique sera perçu comme un geste mémoriel à part entière, doté d’une dimension corporelle et permettant de rejouer l’archive.
Le répertoire du fado ou la tradition en action
Authors: Patrix Pénélope 
Published: November 2017

Cet article aborde le fado par le prisme du répertoire, un concept fortement structurant dans les pratiques et sans cesse débattu par les acteurs. Ce choix permet de réfléchir à ce qui fait l’unité, la continuité et la créativité de cette chanson intermédiale, à la fois traditionnelle et moderne, orale et écrite, performative et médiatique. Le fado peut dès lors être abordé comme un art de la reprise : chaque interprète, en se réappropriant des éléments du répertoire et en proposant de nouvelles configurations lors de sa performance, réactive et renouvelle ce dernier, tout en laissant sa trace dans une mémoire collective des interprétations. On adopte ici une perspective historique afin d’observer comment le répertoire est réinvesti et redéfini à chaque époque, et quels sont les affects, les valeurs et les mémoires que ses mises en oeuvre véhiculent.
Reconstituer Waterloo dans les années 1960 : l’histoire selon Marcel Broodthaers et Norbert Brassinne
Authors: Fourgeaud Nicolas 
Published: November 2017

Avec cet article, on souhaiterait faire le portrait (contextuel, institutionnel, médiatique) de deux acteurs fondamentalement différents, mais qui font de la reconstitution historique un enjeu central de leurs pratiques dès la fin des années 1960 et la rapportent, dans un cas comme dans l’autre, à un même lieu, le champ de bataille de Waterloo, en Belgique francophone : l’artiste bruxellois Marcel Broodthaers (1924–1976) et le commerçant/reconstituteur wallon Norbert Brassine (1907–1988). En plus d’analyser quel rapport à l’histoire et à la reconstitution développent ces deux non-historiens très distincts à travers leurs actions, leurs productions ou leurs apparitions médiatiques, cet article vise aussi à revenir sur une période où la reconstitution historique en était à ses balbutiements à Waterloo, la fin des années 1960. Ce double portrait se propose donc comme une archéologie très localisée des usages et représentations de la reconstitution historique.
La problématique des mineures en fugue : une question de protection ou de développement ?
Authors: Hamel1 Sylvie 
Published: November 2017

Cet article présente les résultats d’une recherche ayant été réalisée de 2008 à 2011 dans le but de réactualiser notre compréhension de l’expérience de la fugue chez les jeunes. Des entretiens semi-dirigés ont été conduits auprès des 90 répondants (jeunes, parents, intervenants des milieux communautaire et institutionnel et policier). Cet article se concentre ici sur le discours des jeunes (n = 33), plus particulièrement sur celui des filles (n = 17), à propos des dangers qu’elles ont rencontrés durant leurs fugues, mais aussi à propos du sens qu’elles donnent à cette expérience qu’elles ont vécue. Les résultats indiquent que les filles ne nient pas les risques de la fugue ni les expériences difficiles pouvant y être associées. Mais, en contrepartie, ces dernières estiment apparemment que ces risques sont secondaires relativement aux impératifs de leur développement qui les mettent dans l’urgence de vérifier leurs capacités à fonctionner seules dans le monde. Sur le plan de l’intervention, les enjeux entourant le développement des jeunes, filles et garçons, semblent être tout aussi importants à considérer que ceux de leur protection.
Future Riverine Inorganic Nitrogen Load to the Baltic Sea From Sweden: An Ensemble Approach to Assessing Climate Change Effects

Published: November 2017

AbstractThe dramatic increase of bioreactive nitrogen entering the Earth's ecosystems continues to attract growing attention. Increasingly large quantities of inorganic nitrogen are flushed from land to water, accelerating freshwater, and marine eutrophication. Multiple, interacting, and potentially countervailing drivers control the future hydrologic export of inorganic nitrogen. In this paper, we attempt to resolve these land‐water interactions across boreal/hemiboreal Sweden in the face of a changing climate with help of a versatile modeling framework to maximize the information value of existing measurement time series. We combined 6,962 spatially distributed water chemistry observations spread over 31 years with daily streamflow and air temperature records. An ensemble of climate model projections, hydrological simulations, and several parameter parsimonious regression models was employed to project future riverine inorganic nitrogen dynamics across Sweden. The median predicted increase in total inorganic nitrogen export from Sweden (2061–2090) due to climate change was 14% (interquartile range 0–29%), based on the ensemble of 7,500 different predictions for each study site. The overall export as well as the seasonal pattern of inorganic nitrogen loads in a future climate are mostly influenced by longer growing seasons and more winter flow, which offset the expected decline in spring flood. The predicted increase in inorganic nitrogen loading due to climate change means that the political efforts for reducing anthropogenic nitrogen inputs need to be increased if ambitions for reducing the eutrophication of the Baltic Sea are to be achieved.
A Global Assessment of Dissolved Organic Carbon in Precipitation
Authors: Safieddine Sarah A. , Heald Colette L. 
Published: November 2017

AbstractPrecipitation is the largest physical removal pathway of atmospheric reactive organic carbon in the form of dissolved organic carbon (DOC). We present the first global DOC distribution simulated with a global model. A total of 85 and 188 Tg C yr−1 are deposited to the ocean and the land, respectively, with DOC ranging between 0.1 and 10 mg C L−1 in this GEOS‐Chem simulation. We compare the 2010 simulated DOC to a 30 year synthesis of measurements. Despite limited measurements and imperfect temporal matching, the model is able to reproduce much of the spatial variability of DOC (r = 0.63), with a low bias of 35%. We present the global average carbon oxidation state (
) as a simple metric for describing the chemical composition. In the atmosphere,

The Effect of Boiling on Seismic Properties of Water‐Saturated Fractured Rock

Published: November 2017

AbstractSeismic campaigns for exploring geothermal systems aim at detecting permeable formations in the subsurface and evaluating the energy state of the pore fluids. High‐enthalpy geothermal resources are known to contain fluids ranging from liquid water up to liquid‐vapor mixtures in regions where boiling occurs and, ultimately, to vapor‐dominated fluids, for instance, if hot parts of the reservoir get depressurized during production. In this study, we implement the properties of single‐ and two‐phase fluids into a numerical poroelastic model to compute frequency‐dependent seismic velocities and attenuation factors of a fractured rock as a function of fluid state. Fluid properties are computed while considering that thermodynamic interaction between the fluid phases takes place. This leads to frequency‐dependent fluid properties and fluid internal attenuation. As shown in a first example, if the fluid contains very small amounts of vapor, fluid internal attenuation is of similar magnitude as attenuation in fractured rock due to other mechanisms. In a second example, seismic properties of a fractured geothermal reservoir with spatially varying fluid properties are calculated. Using the resulting seismic properties as an input model, the seismic response of the reservoir is then computed while the hydrothermal structure is assumed to vary over time. The resulting seismograms demonstrate that anomalies in the seismic response due to fluid state variability are small compared to variations caused by geological background heterogeneity. However, the hydrothermal structure in the reservoir can be delineated from amplitude anomalies when the variations due to geology can be ruled out such as in time‐lapse experiments.
The Influence of Plumbing System Structure on Volcano Dimensions and Topography
Authors: Castruccio Angelo , Diez Mikel , Gho Rayen 
Published: November 2017

AbstractVolcano morphology has been traditionally studied from a descriptive point of view, but in this work we took a different more quantitative perspective. Here we used volcano dimensions such as height and basal radius, together with the topographic profile as indicators of key plumbing system properties. We started by coupling models for the ascent of magma and extrusion of lava flows with those for volcano edifice construction. We modeled volcanic edifices as a pile of lavas that are emitted from a single vent and reduce in volume with time. We then selected a number of arc‐volcano examples to test our physical relationships and estimate parameters, which were compared with independent methods. Our results indicate that large volcanoes (>2,000 m height and base radius >10 km) usually are basaltic systems with overpressured sources located at more than 15 km depth. On the other hand, smaller volcanoes (<2,000 m height and basal radius <10 km) are associated with more evolved systems where the chambers feeding eruptions are located at shallower levels in the crust (<10 km). We find that surface observations on height and basal radius of a volcano and its lavas can give estimates of fundamental properties of the plumbing system, specifically the depth and size of the magma chamber feeding eruptions, as the structure of the magmatic system determines the morphology of the volcanic edifice.

(−)‐Epigallocatechin‐3‐O‐gallate (EGCG), present in green tea, exhibits antioxidant and antiallergy effects. EGCG3″Me, a 3‐O‐methylated derivative of EGCG, has been reported to show similar biological functions; the inhibitory activity of EGCG3″Me in a mouse allergy model was more potent than that of EGCG, probably due to the efficiency of absorption from the intestine. However, the functional potency of these EGCGs is controversial in each disease model. We previously observed that EGCG suppressed inflammatory bone resorption and prevented alveolar bone loss in a mouse model of periodontosis. In this study, we examined the role of EGCG3″Me in bone resorption using a mouse model of periodontitis. Lipopolysaccharide (LPS)‐induced osteoclast formation was suppressed by adding EGCG3″Me to cocultures of osteoblasts and bone marrow cells, and LPS‐induced bone resorption was also inhibited by EGCG3″Me in calvarial organ cultures. EGCG3″Me acted on osteoblasts and suppressed prostaglandin E (PGE) production, which is critical for inflammatory bone resorption, by inhibiting the expression of COX‐2 and mPGES‐1, key enzymes for PGE synthesis. In osteoclast precursor macrophages, EGCG3″Me suppressed RANKL‐dependent differentiation into mature osteoclasts. In a mouse model of periodontitis, LPS‐induced bone resorption was suppressed by EGCG3″Me in organ culture of mouse alveolar bone, and the alveolar bone loss was further attenuated by the treatment of EGCG3″Me in the lower gingiva in vivo. EGCG3″Me may be a potential natural compound for the protection of inflammatory bone loss in periodontitis.
