ABSTRACT
The trans-Neptunian objects (TNOs) preserve evidence of planet building processes in their orbital and size distributions. While all populations show steep size distributions for large objects, a relative deficit of Neptunian trojans and scattering objects with diameters of D < 100 km has been detected. We investigated this deficit with a 32 square degree survey, in which we detected 77 TNOs that are brighter than a limiting r-band magnitude of 24.6. Our plutino sample (18 objects in 3:2 mean-motion resonance with Neptune) shows a deficit of D < 100 km objects, rejecting a single power-law size distribution at >99% confidence. Combining our survey with the Canada–France Ecliptic Plane Survey, we perform a detailed analysis of the allowable parameters for the plutino size distribution, including knees and divots. We surmise the existence of 9000 ± 3000 plutinos with an absolute magnitude of H

r
≤ 8.66 and

with H

r
≤ 10.0 (95% confidence). Our survey also discovered one temporary Uranian trojan, one temporary Neptunian trojan, and one stable Neptunian trojan, for which we estimate populations of

,

, and

with H

r
≤ 10.0, respectively. All three populations are thus less numerous than the main belt asteroids (592 asteroids with H

r
≤ 10.0). With such population sizes, the temporary Neptunian trojans cannot be previously stable trojans diffusing out of the resonance now; they must be recently captured Centaurs or scattering objects. As the bias against the detection of objects grows with larger semimajor axes, our discovery of three 3:1 resonators and one 4:1 resonator adds to the growing evidence that the high-order resonances are far more populated than is typically predicted.

ABSTRACT
We report the detections of a giant planet (MARVELS-7b) and a brown dwarf (BD) candidate (MARVELS-7c) around the primary star in the close binary system, HD 87646. To the best of our knowledge, it is the first close binary system with more than one substellar circumprimary companion that has been discovered. The detection of this giant planet was accomplished using the first multi-object Doppler instrument (KeckET) at the Sloan Digital Sky Survey (SDSS) telescope. Subsequent radial velocity observations using the Exoplanet Tracker at the Kitt Peak National Observatory, the High Resolution Spectrograph at the Hobby Eberley telescope, the “Classic” spectrograph at the Automatic Spectroscopic Telescope at the Fairborn Observatory, and MARVELS from SDSS-III confirmed this giant planet discovery and revealed the existence of a long-period BD in this binary. HD 87646 is a close binary with a separation of ∼22 au between the two stars, estimated using the Hipparcos catalog and our newly acquired AO image from PALAO on the 200 inch Hale Telescope at Palomar. The primary star in the binary, HD 87646A, has

= 5770 ± 80 K, log g = 4.1 ± 0.1, and [Fe/H] = −0.17 ± 0.08. The derived minimum masses of the two substellar companions of HD 87646A are 12.4 ± 0.7

and 57.0 ± 3.7

. The periods are 13.481 ± 0.001 days and 674 ± 4 days and the measured eccentricities are 0.05 ± 0.02 and 0.50 ± 0.02 respectively. Our dynamical simulations show that the system is stable if the binary orbit has a large semimajor axis and a low eccentricity, which can be verified with future astrometry observations.

ABSTRACT
NGC 2420 is a ∼2 Gyr old well-populated open cluster that lies about 2 kpc beyond the solar circle, in the general direction of the Galactic anti-center. Most previous abundance studies have found this cluster to be mildly metal-poor, but with a large scatter in the obtained metallicities. Detailed chemical abundance distributions are derived for 12 red-giant members of NGC 2420 via a manual abundance analysis of high-resolution (R = 22,500) near-infrared (λ1.5–1.7 μm) spectra obtained from the Apache Point Observatory Galactic Evolution Experiment (APOGEE) survey. The sample analyzed contains six stars that are identified as members of the first-ascent red giant branch (RGB), as well as six members of the red clump (RC). We find small scatter in the star-to-star abundances in NGC 2420, with a mean cluster abundance of [Fe/H] = −0.16 ± 0.04 for the 12 red giants. The internal abundance dispersion for all elements (C, N, O, Na, Mg, Al, Si, K, Ca, Ti, V, Cr, Mn, Co and Ni) is also very small (∼0.03–0.06 dex), indicating a uniform cluster abundance distribution within the uncertainties. NGC 2420 is one of the clusters used to calibrate the APOGEE Stellar Parameter and Chemical Abundance Pipeline (ASPCAP). The results from this manual analysis compare well with ASPCAP abundances for most of the elements studied, although for Na, Al, and V there are more significant offsets. No evidence of extra-mixing at the RGB luminosity bump is found in the 12C and 14N abundances from the pre-luminosity-bump RGB stars in comparison to the post-He core-flash RC stars.
CLUMPY DISKS AS A TESTBED FOR FEEDBACK-REGULATED GALAXY FORMATION

ABSTRACT
We study the dependence of fragmentation in massive gas-rich galaxy disks at z > 1 on stellar feedback schemes and hydrodynamical solvers, employing the GASOLINE2 SPH code and the lagrangian mesh-less code GIZMO in finite mass mode. Non-cosmological galaxy disk runs with the standard delayed-cooling blastwave feedback are compared with runs adopting a new superbubble feedback, which produces winds by modeling the detailed physics of supernova-driven bubbles and leads to efficient self-regulation of star formation. We find that, with blastwave feedback, massive star-forming clumps form in comparable number and with very similar masses in GASOLINE2 and GIZMO. Typical clump masses are in the range 107–108
M
⊙, lower than in most previous works, while giant clumps with masses above 109
M
⊙ are exceedingly rare. By contrast, superbubble feedback does not produce massive star-forming bound clumps as galaxies never undergo a phase of violent disk instability. In this scheme, only sporadic, unbound star-forming overdensities lasting a few tens of Myr can arise, triggered by non-linear perturbations from massive satellite companions. We conclude that there is severe tension between explaining massive star-forming clumps observed at z > 1 primarily as the result of disk fragmentation driven by gravitational instability and the prevailing view of feedback-regulated galaxy formation. The link between disk stability and star formation efficiency should thus be regarded as a key testing ground for galaxy formation theory.
Le hip-hop comme élément identitaire dans le 9-3
Authors: Piolet Vincent 
Published: October 2016

À travers le parcours du groupe de rap Suprême NTM, on découvre comment le hip-hop a constitué un élément identitaire fort en revendiquant notamment le quartier d’origine des deux rappeurs, à savoir le 9-3. comme ils l’ont défini. Cette fierté du territoire a pris plusieurs formes, notamment par le tag où, là encore, les 93 NTM arborent fièrement leur lieu d’appartenance dans un esprit de compé­tition avec les tagueurs d’autres endroits. Très vite, les rappeurs sui­­vront cette ferveur et émergeront des groupes revendiquant le 9-4. ou le 9-2.

Manuels des origines, origines des manuels : l’enseignement de la littérature, de Batteux à Lanson
Authors: Canvat Karl 
Published: October 2016

On analyse ici les transformations profondes de l’enseignement de la littérature en France, entre le XVIII e et le début du XX e siècle, à travers quelques manuels emblématiques. Les deux premiers (Batteux et La Harpe) sont représentatifs d’une certaine conception de la littérature comme moyen de transmettre une éducation fondée sur des valeurs morales, mais aussi civiques et religieuses ; ils offrent des « modèles » d’écriture par imitation des grands auteurs. Ces manuels instaurent une approche de l’enseignement de la littérature qui se transforme radicalement à la fin du XIX e siècle, avec les travaux de G. Lanson. Celui-ci préconise l’explication de textes et l’histoire de la littérature comme nouveaux procédés didactiques, marquant une rupture avec le modèle rhétorique fondé sur les grandes catégories que sont les genres. Les changements de modèles de la littérature comme discipline scolaire sont lisibles à travers l’étude des manuels ; leurs variations et leurs constantes permettent d’éclairer la réflexion sur la situation actuelle.
La connaissance de soi
Authors: Valdivia Fuenzalida José Antonio 
Published: October 2016

Ce travail propose une analyse détaillée d’un argument de Pierre de Jean Olivi utilisé dans l’article 19 de son Impugnatio quorundam articulorum Arnaldi Galliardi (1282) contre une thèse professée par Thomas d’Aquin à propos de la connaissance que l’âme humaine a d’elle-même. Le texte d’Olivi cherche à prouver que l’homme peut connaître directement des réalités immatérielles, dont son âme. Le but de cette analyse est double. D’une part, il s’agit de mettre en évidence une difficulté suscitée par la théorie thomasienne de la connaissance que l’âme humaine a d’elle-même, tout du moins selon la façon dont cette théorie apparaît dans les textes disponibles ; d’autre part, de comparer l’argument et la thèse olivienne à l’interprétation que certains thomistes ont élaborée à propos de la doctrine thomasienne. Cette comparaison révèle une similitude qui suscite un questionnement critique à propos de telles interprétations.
« Les garçons en ont assez »
Authors: Collaud Yves 
Published: October 2016

Entre 1946 et 1948, le directeur de la Maison d’éducation de Vennes, Henri Bourquin, est mis en cause dans une affaire d’abus sexuels. Bien que les débats du Grand Conseil vaudois ainsi que la presse de l’époque parlent de cette affaire, les autorités ont tout fait afin de rester discrètes autour de celle-ci. Notre article propose de s’intéresser aux pièces conservées afin de comprendre pourquoi les abus commis par Bourquin n’ont pas donné lieu à un scandale. Pour cela, nous nous intéresserons aux différents documents afin de suivre trois axes de recherche : quels sont les mécanismes qui ont permis d’éviter un scandale, comment peut-on comprendre la survenue des abus dans le contexte de l’institution et comment la parole des enfants a-t-elle été reçue.
La représentation de la sexualité des femmes incarcérées au petit écran.
Authors: Beaulieu Julie 
Published: October 2016

Cette étude porte sur la représentation de la sexualité dans la première saison de la populaire télésérie québécoise Unité 9 (2012-2013). L’analyse de segments-clés de la série met en avant la complexité des identités sexuelles, de même que la marginalisation du milieu carcéral féminin dans lequel la sexualité peut être vécue et comprise comme « déviante », notamment en référence à la norme hétérosexuelle en vigueur à l’extérieur des murs. Tirant profit des réflexions de Judith Butler, et plus largement des approches sociologiques, féministes et queer de la représentation de la sexualité, l’analyse permet entre autres de cerner dans quelle mesure les désirs et pratiques sexuelles peuvent s’éloigner (temporairement ou non) de l’orientation sexuelle vécue avant l’incarcération. C’est-à-dire comment l’isolement et le confinement peuvent modifier les comportements sexuels des femmes incarcérées, et, conséquemment, bouleverser leur identité sexuelle.

<p>The surfactant complex, thanks to its multiple actions including decrease of surface- tension and antimicrobial activity, plays a fundamental role in newborn survival, lowering the risk of respiratory distress syndrome. The aim of this work was to determine if the synthesis of two surfactant proteins (SP), SPA and pro-SPB, shows some inter-individual variability during lung development in the intrauterine life. Immunoreactivity for SPA and pro-SPB was investigated in the lungs of 40 subjects, including 15 fetuses, ranging from 14 to 22 weeks of gestation, and 25 neonates, from 24 to 41 weeks. Lung samples were formalin fixed, paraffin-embedded and routinely processed. SPA and pro-SPB were detected utilizing commercial antibodies. A semi-quantitative grading system (1 to 4) was applied, based on the number of reactive cells and the intensity of immunostaining. Surfactant protein immunostaining was found in three compartments: bronchi, bronchioles and alveoli, starting from 14 weeks of gestation in the bronchial epithelium and from the 21<sup>st</sup> week in the alveolar spaces. Differences were found regarding SPA and pro-SPB expression in the vast majority of subjects: in some lungs, SPA was more expressed whereas in others pro-SPB showed an higher degree of immunoreactivity. The expression of both surfactant proteins was not strictly correlated with gestational age. Whereas the highest levels of reactivity were detected in at term neonates, on the other hand one case with grade 3 was detected at 22 weeks and one negative case for both proteins was observed at 31 weeks. Our data clearly show a marked inter-individual variability regarding the production of SPA and pro-SPB and suggest the existence of other epigenetic factors, acting during gestation, that might influence surfactant production and, consequently, the survival potential of neonates at birth. </p>

Agustín de Betancourt and Molina was one of the most distinguished engineers of the eighteenth and nineteenth century with numerous contributions to various fields of engineering, including civil engineering. This research shows the process followed in the documentation of the cultural heritage of that canary engineer, especially in the geometric documentation of the wind machine to drain marshy grounds designed in 1789. The baseline information has been recovered from the Canary Orotava Foundation of History of Science who has spent years collecting information about the Project Betancourt, in particular, planimetric information as well as a small report on its operation and description of parts of machine. From this information, we have obtained its 3D reconstruction using CAD techniques with the cooperation of Solid Edge ST7 parametric software, which has enabled to obtain the 3D model as well as different detail plans and exploded views.

España ha intensificado la aplicación de políticas encaminadas a la reducción del número de accidentes y de víctimas, durante la última década, y ha alcanzado un elevado nivel de éxito en esta tarea, situando a nuestro país en un puesto muy destacado entre los países de Europa y del mundo en relación a la seguridad vial. En el año 2013, España ocupó el quinto puesto en el grupo de países de la UE-28 en el indicador muertos por millón de habitante. Un indicador análogo con datos de exposición no existe a nivel europeo, en tanto el denominador (la exposición) es una magnitud de difícil obtención. El logro de nuevas metas exige medidas específicas dirigidas a ámbitos y colectivos con características diferentes, y para ello es necesario un mejor conocimiento de los verdaderos niveles de riesgo de determinados grupos de usuarios, definidos por criterios de género, o edad, o de tipos de vehículos y características constructivas, prestaciones o eficacia de sistemas de seguridad, entre otros factores. En el caso de los vehículos, existen datos de distancias recorridas en diferentes periodos, recogidos en las fichas de inspección técnica, e incorporados, desde hace unos años, en bases de datos gestionadas por las comunidades autónomas y por la DGT, pero estos datos están siendo escasamente explotados.En el presente trabajo se presenta una metodología de análisis de los datos obtenidos en las inspecciones técnicas de los vehículos, y de estimación de la exposición (veh-km anual) de diferentes grupos de vehículos (según tipo, edad y potencia, entre otras variables determinantes) que pueden presentar diferencias significativas en sus niveles de exposición. La metodología, que incluye la creación de bases limpias y la formación de conglomerados de vehículos con elevada homogeneidad en el valor de su movilidad, se ha aplicado a una muestra de autobuses articulados a modo de estudio piloto. Con este trabajo se pretende contribuir a un mejor conocimiento de los verdaderos niveles de riesgo de diferentes grupos de vehículos del parque español.DOI: http://dx.doi.org/10.4995/CIT2016.2016.1990
CARONTE project: Creating an Agenda for Research on Transportation Security
Authors: Leon Bello Jorge , Gonzalez Viosca Emilio 
Published: October 2016

Europe’s prosperity relies on effective transport systems. Any attacks and disturbances to land freight and passenger transport would have significant impact on economic growth, territorial cohesion, social development and the environment. Unfortunately, there are weaknesses in the land transport security.The objective of CARONTE project is define a future research agenda for security in land transport that focuses on core gaps caused by emerging risks while avoiding any doubling-up of research elsewhere. Its research agenda will cover all threats, including cyber-crime, and security aspects across all modes of land transportation. At the same time, it will respect the fundamental human rights and privacy of European citizens. The step-by-step method of CARONTE’s consortium has analyzed the state of the art and emerging risks; has identified gaps, analyses and assessments of potential solutions; and has produced an overall research agenda for the future. CARONTE’s results will answer the following questions among others: Which existing research projects merit a follow up and extension?Where are the combinations or synergy effects to be attended?Which themes and topics should be elaborated in new research projects?Who should be involved and integrated in future research projects (stakeholders, authorities, etc.)? The CARONTE consortium includes universities and research institutes, companies, and end-users providing with experience in research and consultancy in transportation, logistics, infrastructure management, security and communications. ITENE - Instituto Tecnológico del Embalaje, Transporte y Logística- has been one of the Project partners among a total of 11 members from eight different countries in the European Union which have also been supported via a High Level Advisory Board.DOI: http://dx.doi.org/10.4995/CIT2016.2016.3272
Auditorías de seguridad vial como políticas para mejorar la seguridad del transporte en la provincia de Chimborazo-Ecuador
Authors: Paredes García Angel Edmundo 
Published: October 2016

La provincia de Chimborazo localizada en el centro del país se encuentra atravesada por una de las principales carreteras denominadas Troncal de la Sierra, la misma que conecta Colombia, Ecuador y Perú. Una auditoría de seguridad vial es un análisis formal que pretende garantizar que un camino, en nuestro caso existente, cumpla con criterios óptimos de seguridad. Dichas auditorías deben ser llevadas a cabo por un equipo de profesionales, cuyos miembros sean independientes del proyecto de la vía. En los últimos dos años la Universidad Nacional de Chimborazo, con sus estudiantes de pregrado, ha realizado Auditorías de Seguridad Vial en las principales vías que ingresan a la provincia de Chimborazo con el fin de reducir los accidentes en dichas carreteras. Gracias a los resultados obtenidos en base a una lista de chequeos realizados en cada vía, se pudo establecer que pese al alto porcentaje de seguridad presente en las vías, existen todavía puntos conflictivos, los mismos que deben ser intervenidos inmediatamente para disminuir el índice de accidentabilidad en nuestras carreteras. Las soluciones más comunes resultado de las auditorías realizadas son: instalación correcta de la señalización, diseño de taludes, iluminación y, de ser necesario, rediseño de la vía. Además se pudo establecer parámetros para determinar las políticas o futuros planes de acción con el fin de mejorar la seguridad en las vías y por ende la seguridad en el transporte.DOI: http://dx.doi.org/10.4995/CIT2016.2016.3386
