Formation of Ultra-short-period Planets by Obliquity-driven Tidal Runaway
Authors: Millholland Sarah C. , Spalding Christopher 
Published: December 2020

Abstract
Small, rocky planets have been found orbiting in extreme proximity to their host stars, sometimes down to only ∼2 stellar radii. These ultra-short-period planets (USPs) likely did not form in their present-day orbits, but rather migrated from larger initial separations. While tides are the probable cause of this migration, the tidal source has remained uncertain. Here, we introduce planetary obliquity tides as a natural pathway for the production of USPs within close-in multiplanet systems. The crucial idea is that tidal dissipation generally forces planetary spin vectors to equilibrium configurations called “Cassini states,” in which the planetary obliquities (axial tilts) are nonzero. In these cases, sustained tidal dissipation and inward orbital migration are inevitable. Migration then increases the obliquity and strengthens the tides, creating a positive feedback loop. Thus, if a planet's initial semimajor axis is small enough (a ≲ 0.05 au), it can experience runaway orbital decay, which is stalled at ultra-short orbital periods when the forced obliquity reaches very high values (∼85°) and becomes unstable. We use secular dynamics to outline the parameter space in which the innermost member of a prototypical Kepler multiple-planet system can become a USP. We find that these conditions are consistent with many observed features of USPs, such as period ratios, mutual inclinations, and occurrence rate trends with stellar type. Future detections of stellar obliquities and close-in companions, together with theoretical explorations of the potential for chaotic obliquity dynamics, can help constrain the prevalence of this mechanism.
Bayesian Analysis of Quasi-periodic Pulsations in Stellar Flares
Authors: Pascoe D. J. , Smyrli A. , Van Doorsselaere T. , Broomhall A.-M. 
Published: December 2020

Abstract
Quasi-periodic pulsations (QPPs) are routinely observed in a range of wavelengths during flares, but in most cases the mechanism responsible is unknown. We present a method to detect and characterize QPPs in time series such as light curves for solar or stellar flares based on forward modeling and Bayesian analysis. We include models for QPPs as oscillations with finite lifetimes and nonmonotonic amplitude modulation, such as wave trains formed by dispersive evolution in structured plasmas. By quantitatively comparing different models using Bayes factors, we characterize the QPPs according to five properties: sinusoidal or nonsinusoidal, finite or indefinite duration, symmetric or asymmetric perturbations, monotonic or nonmonotonic amplitude modulation, and constant or varying period of oscillation. We demonstrate our method and show examples of these five characteristics by analyzing QPPs in white-light stellar flares observed by the Kepler space telescope. Different combinations of properties may be able to identify particular physical mechanisms and so improve our understanding of QPPs and allow their use as seismological diagnostics. We propose that three observational classes of QPPs can be distinguished: decaying harmonic oscillations, finite wave trains, and nonsinusoidal pulsations.
Marxismes et Critique de la valeur
Authors: Sobel Richard 
Published: December 2020

Promouvant un « Marx ésotérique-hétérodoxe » contre un « Marx exotérique-orthodoxe », le courant actuel Critique de la valeur entend élaborer une critique sociale sur la base d’une interprétation radicale de l’analyse structurale par Marx du capitalisme. Tout en en soulignant l’apport antinaturaliste original, cet article se propose de montrer en quoi ce courant ne fait que reformuler à nouveaux frais une approche déterministe qui vide la praxis de toute épaisseur ontologique, ce qui le prive des moyens de rendre compte du « monde » capitaliste en tant que tel et du coup d’en penser la transformation hors d’une logique du tout ou rien.
Le droit au séjour pour soins, laboratoire de l’état d’urgence sanitaire
Authors: Klausser Nicolas 
Published: December 2020

Les outils juridiques imposés dans le cadre de l’état d’urgence sanitaire partagent avec la police des étrangers en France un objectif commun : le contrôle et la surveillance des déplacements des populations. Pour observer la « circulation du virus », immobiliser, constituer des fichiers de données personnelles – qui échapperaient aisément à leurs propriétaires – et enfin géolocaliser, représentent autant d’opérations attentatoires à la liberté de circulation qui ne peuvent qu’intéresser les préposés à la maîtrise des flux migratoires.
En quarantaine à la frontière franco-italienne
Authors: Hanus Philippe 
Published: December 2020

En période d’épidémie, l’étranger est souvent accusé de colporter la maladie et les migrations sont perçues comme des menaces biologiques qu’il faut « bloquer » aux frontières. Mais les politiques d’endiguement ne se justifient-elles que par des considérations prophylactiques ? L’auteur retrace, à travers l’épisode de choléra qui touche l’Europe en 1884-1885, « la fabrique » d’un événement et sa politisation où gestion sanitaire et politique souverainiste de contrôle de populations s’inspirent l’une l’autre.
Corine Pelluchon, Éthique de la considération , Paris, Seuil, 2018, 288 pages
Authors: Quentin Bertrand 
Published: December 2020

Pendant des siècles, Dieu, le cosmos et la tradition ont fondé l’éthique. Avec les Lumières nos sociétés industrialisées se sont ensuite focalisées sur la raison. Mais face à certains enjeux contemporains, elle n’apparaît plus non plus comme un guide infaillible vers notre bien. Trois principaux défis sont là. Le premier est environnemental. Le second est la cause animale. Le troisième est celui d’une renaissance du système démocratique devant le délitement qui l’accompagne aujourd’hui amenant à réaffirmer la primauté du politique sur l’économie.. Pour relever ces défis de façon structurelle il nous faudra une métamorphose de nos comportements et pouvoir passer du nihilisme à « l’âge de la considération ». Corine Pelluchon nous détaille un chemin qui construit métaphysiquement, psychologiquement et politiquement ce concept de « considération », issu de Bernard de Clairvaux mais repensé par ses soins.
Les débuts de la mutualité dans le Nord de la France et en Belgique, accommodation ou résistance à la mise au travail industriel ?
Authors: Tilly Pierre , Touchelay Béatrice 
Published: December 2020

Le dynamisme des coopératives de production et de consommation et celui des mutualités en France, particulièrement dans le Nord, se retrouve également en Belgique au travers du mouvement coopératif belge d’initiative ouvrière, chrétienne et socialiste. Ces mouvements illustrent à la fois le foisonnement et l’originalité des initiatives des travailleurs et des patrons nordistes en matière de solidarité à la fin du xix e siècle. Les « modèles » belge et français se distinguent cependant par leur degré de politisation. En effet, si initialement les fraternités s’inscrivent dans l’oppositon politique en France, elles rentrent dans le rang au cours du xix e siècle tandis que les coopératives belges s’inscrivent ouvertement dans le réformisme et la recherche d’une alternative au capitalisme, ou du moins d’un adoucissement de ses règles. Le développement du mutualisme dans le Nord n’est ni une simple captation paternaliste, ni la manifestation de l’emprise des notables ou des Églises sur les populations ouvrières. Il résulte de la prise de conscience par une partie des ouvriers, des patrons et des responsables politiques de la nécessité d’aménager les effets de l’industrialisation et de la salarisation. Le réformisme de ces aspirations rencontre un terrain porteur dans des régions massivement industrialisées au xix e siècle.

The obscurity of the physical: an objection to Chalmers’ conceivability argument
Authors: Moreira Felipe G. A. 
Published: December 2020

A zombie world is a possible world in which all the microphysical truths are identical to the truths in our world, but no one is phenomenally conscious. A zombie is an individual in a possible world whose microphysical truths are identical to the microphysical truths of an individual in our world, but who has none of the phenomenal conscious experiences of the individual in our world. An inverted is an individual in a possible world whose microphysical truths are not only identical to the microphysical truths of an individual in our world, but who also has phenomenal conscious experiences. These experiences, however, are qualitatively different from the ones of the individual in our world. The first premise of Chalmers’ conceivability argument against materialism is that a zombie world, a zombie and an inverted are ideally conceivable. This paper rejects this premise in claiming that: given that current physics does not allow philosophers to establish a clear concept of the physical that could be opposed to something else non-physical, a zombie world, a zombie and an inverted are merely prima facie, but not ideally conceivable. This objection is called the Obscurity of the Physical Objection.Key-words: Zombies, qualia, conceivability, possibility, physics.
Preservation strategies for student affairs records at the University of Venda in South Africa
Authors: Netshakhuma Sidney 
Published: December 2020

Student affairs records are essential components in addressing basic functionalities in the university environment as they serve diverse purposes such as the life of a student on the campus. However, these records are often not preserved properly especially at universities in rural settings. This study assessed student affairs records, with consideration to preservation strategy at the University of Venda in South Africa. Data were collected through interviews with ten purposively selected staff members from student affairs division. The key findings reveal that while the university has an archive service within the library, the responsibility of preserving student records lies with records management division that resides within the registrar’s office. However, there is no preservation strategy for student affairs records. It is concluded that collaboration between student affairs and records and archives department enhance to collect the student affairs records. A comprehensive study on the management of student affairs records in South African universities is recommended.
Institutional Analysis of Adoption of Agroforestry Practices in the Eastern Cape Province of South Africa
Authors: Zerihun Mulatu Fekadu 
Published: December 2020

Agroforestry practices are innovations developed in response to problems associated with inappropriate land use practices. The latter refers to the use of agricultural land for non-agricultural purposes because of an increase in urbanisation, rapidly developing industry, and investments, and, finally, gaps in laws and regulations (Cengiz, 2013). Agroforestry practices are land-based economic development strategies with a perceived positive role in supporting rural livelihoods. Using a logistic regression model with cross-sectional data, this study explores the impact of institutional factors and incentive mechanisms that affect the adoption of agroforestry innovations. The study finds that a larger number of extension services, access to credit, access to extension, information exchange among farmers, trust in local institutions, active participation in social groups and organisations, and prior exposure to agricultural technologies are the variables that positively affect the adoption of agroforestry innovations in the study area. These findings have policy implications in promoting integrated rural development in the Eastern Cape Province of South Africa.
Adsorption of carbon dioxide on MIL53(Al), CuBTC and K- NaX zeolite
Authors: Cakicioglu-Ozkan Fehime 
Published: December 2020

CO2 adsorption on K exchanged NaX zeolites, and metal organic frameworks (MOFs), namely Cu-BTC and MIL53 (Al) was studied at 5 °C and 25 °C. Exchange via ultrasonic and traditional methods, was conducted at 50 °C and 70 °C. The maximum replacement of Na+ ion with K+ ion in the extra framework of zeolite was increased from 76% to 83% with increasing temperature from 50 °C to 70 °C in the ultrasonic method which is more effective than traditional one. Compared with the zeolites, the MOF adsorbents used in this work have higher Langmuir specific surface area values namely 1278, 1473 and about 1000 m2/g for MIL 53, Cu-BTC and zeolite adsorbents respectively. The resulting CO2 isotherms can be well represented by the Toth equation. Comparison of the isosteric heat of adsorption at zero loading shows that CO2 was adsorbed more weakly on MOFs than zeolites.
KC-390 E A PROJEÇÃO DO BRASIL NO CENÁRIO INTERNACIONAL
Authors: Pereira Bruno Américo , Jasper Flavio Neri Hadmann 
Published: December 2020

Vivemos um momento de transição na política externa. Devido a esta situação internacional, a ajuda humanitária passou a ter papel importante para minorar os efeitos negativos a população, causados por desastres naturais ou conflitos violentos. Este artigo tem por objetivo analisar a projeção do governo brasileiro no cenário internacional. A nova aeronave militar KC-390, projetada pela Empresa Brasileira de Aeronáutica, é o meio que permitirá a inserção brasileira nesse contexto. Para identificar esta notoriedade, realizou-se uma análise das capacidades operacionais através dos requisitos técnicos, logísticos e industriais, estipulados na fase de pré-desenvolvimento do projeto. Em seguida foi demonstrada a aplicabilidade do futuro vetor aéreo nas questões de ajuda humanitária a nível global e suas capacidades em missões de conflito real. Após a rodada de análise e demonstração, evidenciou-se que o KC-390 ratificará a prevalência de relações internacionais pacíficas e a projeção do País no campo da segurança cooperativa, com suas medidas de confiança mútua. Foi possível identificar também que o KC-390 possibilitará, em uma visão prospectiva, uma maior participação brasileira nas operações de paz e proporcionará uma maior assistência material e logística, prestadas para fins de conforto social humanitários nos esforços para o desenvolvimento da paz mundial. Apesar do cenário estável do entorno geopolítico imediato o Brasil não pode prescindir da capacidade militar de cooperação internacional em missões da ONU. O crescimento do país nesse tema pode, então, ser analisado sob o aspecto do crescimento, complexidade e maturidade que a indústria aeronáutica no Brasil atingiu. A natureza da reestruturação da indústria brasileira de defesa também será compreendida, com fulcro em tecnologias sob o domínio nacional fruto da cooperação vasta e multifacetada com parceiros internacionais. Assim, o produto desse trabalho é fundamental para entender o propósito adicional de projeção do Brasil nas relações de cooperação internacional com outros países.
Pengaruh Home Industry terhadap Peningkatan Pendapatan Masyarakat Sekitar
Authors: Budiana Budiana 
Published: December 2020

Today, home industry is part of an economic driver which has a very important position. This causes the village community or village government to create economic business opportunities to meet the needs of their lives. One that is currently up and running is the skin cracker home industry. The development of the skin cracker home industry supports the economy apart from agriculture. If only the economic growth was supported by agriculture, there would certainly be many shortcomings because the available land area was very limited. Economic improvement must be marked by an increase in people's income. This increase in income is certainly helped by the presence of the skin cracker home industry. People can be absorbed into working as casual daily laborers by getting income to meet their daily needs. Therefore, researchers conducted literature studies, interviews and observations about the influence of home industry on increasing the income of the surrounding community. Habit in realizing the independence of village communities. In this study, the research method used is descriptive qualitative in the form of interviews to find data and direct observation. This research is certainly expected to find the influence of home industry and increase in income of the surrounding community in Rancaputat village, Sumberjaya sub-district, Majalengka district.

Published: December 2020

Este artículo presenta el Análisis de Descargas Parciales empleando Técnicas Neuronales. Las máquinas rotativas empleadas en la industria suelen presentar fallas en los aislamientos causadas por falta de mantenimiento y desconocimiento del estado de los mismos. Es importante la realización de pruebas periódicas y evaluaciones continuas del estado del aislamiento para garantizar el correcto funcionamiento de las máquinas. Uno de los métodos empleados para la detección de estas fallas es el de Descargas Parciales. Las cuales consisten en pequeñas descargas producidas en una porción de gas que queda disuelto en el aceite o dieléctrico que constituye el aislamiento de las máquinas eléctricas. En este trabajo de investigación se realiza un análisis de dos trabajos desarrollados en torno a las descargas parciales, donde se han implementado técnicas de inteligencia artificial. Los resultados mostraron una alta efectividad de las redes neuronales para lograr la clasificación de las descargas parciales y aportar en el mantenimiento de equipos eléctricos de alta potencia.

Autismo, educação e inclusão
Authors: Ferreira da Cunha Nathalia 
Published: December 2020

O autismo é um tema que apresenta uma considerável discussão no universo científico como no ambiente escolar. É uma realidade cada vez mais presente, sendo evidenciada pelos avanços das pesquisas na área, bem como definição de seus diferentes espectros. Através do levantamento do estado da arte sobre o tema do autismo e das políticas públicas, buscou-se compreender como o autismo é classificado, o perfil do autista, os desafios da educação no viés da inclusão e as discussões a nível de políticas públicas que asseguraram os direitos à pessoas com deficiência e autistas no Brasil. Na última década grandes avanços foram obtidos nessa área graças à lei 12764/2012 que trata da Política Nacional de Proteção dos Direitos da Pessoa com Transtorno do Espectro Autista, bem como a lei 13146/2015 que promulgou a Lei Brasileira de Inclusão da Pessoa com Deficiência (Estatuto da Pessoa com Deficiência). Com avanços quanto às discussões pertinentes à forma como deve se dar o processo de ensino aprendizagem através de ferramentas pedagógicas voltadas a cada especificidade, a presença de mediadores e o processo de tratamento assegurado junto ao serviço público de saúde foram importantes aspectos apontados por essas leis. O processo de inclusão caminha para de fato incluir, bem como incentivar o entendimento da pluralidade e do respeito às diferenças. Este processo ainda não atingiu o seu ideal, assim como a luta daqueles que buscam melhores condições aos autistas não findou, mas as conquistas já representam avanços e melhores entendimentos sobre o assunto.
