OBSOLESCÊNCIA PROGRAMADA: POSTURA QUESTIONÁVEL DO SETOR MERCANTIL ANTE AOS PRINCÍPIOS CONSTITUCIONAIS
Authors: Seixas Ana Paula Adorno , Carvalho Marina Rúbia M. Lôbo De
Published: October 2021

A estratégia mercantil denominada de obsolescência programada não é meramente atual, haja vista que está arraigada na sociedade há séculos. Partindo desse pressuposto, as razões de seu estudo é justamente o fato de ser algo secular que ainda persiste e que causa graves e, muitas vezes, irreparáveis danos em várias esferas. Ao mesmo tempo em que a conjuntura social e ambiental é afetada, observa-se que, paralelamente, há uma preocupação com o setor mercantil, que é justamente a mola propulsora para o desenvolvimento social e financeiro dos indivíduos e da sociedade. Desse modo, a importância do estudo reside também na necessidade de mudança de tal cenário, para propiciar a efetivação do princípio do não retrocesso ambiental e do desenvolvimento sustentável. É necessário que exista uma conduta compatível com os preceitos fundamentais, para que não haja uma afronta à ordem constitucional e ao Estado Democrático de Direito.

Mentir para vacunarse
Authors: Vargas Pedro Ernesto
Published: October 2021

No hace mucho tiempo, un grupo pequeño pero significativo de ciudadanos nacionales cruzaron las fronteras, surcaron los aires, se mecieron con las olas para vacunarse contra COVID-19 porque en el horizonte nacional, no había señales de protegerse con ellas, por no pertenecer a alguno de los grupos prioritarios.  La escasez del recurso financiero y de las vacunas obligó considerar la necesidad de proteger primero con la vacuna a los grupos vulnerables, conocidos en ese momento, como las personas mayores de 70 años y el personal de salud, de las instituciones hospitalarias.  Aún con vacunas suficientes, el más frágil no debe hacer filas y esperar porque otros gozan de los privilegios de la familiaridad, la amistad o la posición social.  Además, en otras latitudes, las vacunas se empezaban a botar al final del día.
Neutrino-dominated Accretion Flows: A Second Nucleosynthesis Factory in Core-collapse Supernovae and Regulating the Iron Markets in Galaxies
Authors: Liu Tong , Qi Yan-Qing , Cai Zhen-Yi , Sun Mouyuan , Qu Hui-Min , Song Cui-Ying
Published: October 2021

Cosmic metals are widely believed to be produced by supernovae (SNe) and compact-object mergers. Here, we discuss the nucleosynthesis of neutrino-dominated accretion flows (NDAFs) with outflows in the centers of core-collapse SNe (CCSNe), and show that the outflows from NDAFs can have a significant contribution to the 56Ni abundances of faint explosions if the masses of the progenitor stars are within about 25–50 M
⊙. Less-massive progenitor stars can produce more 56Ni than their more-massive counterparts in the NDAF outflow nucleosynthesis channel. Therefore, we find that the total (i.e., CCSNe and NDAF outflows) 56Ni mass per CCSN depends only weakly upon the mass of the progenitor star. In terms of metallicity evolution, the ratio of 56Fe (produced by the decay of 56Ni) mass to the initial total gas mass can increase by ∼1.95 times if the upper limits of the nucleosynthesis yields from NDAF outflows and CCSNe are considered. Our results might have significant implications for the chemical evolution of the solar neighborhood, galaxies, and active galactic nuclei.
Second-scale Submillimeter Variability of Sagittarius A* during Flaring Activity of 2019: On the Origin of Bright Near-infrared Flares
Authors: Murchikova Lena , Witzel Gunther
Published: October 2021

In 2019, Sgr A*—the supermassive black hole in the Galactic Center—underwent unprecedented flaring activity in the near-infrared (NIR), brightening by up to a factor of 100 compared to quiescent values. Here we report Atacama Large Millimeter/submillimeter Array (ALMA) observations of Sgr A*'s continuum variability at 1.3 mm (230 GHz)—a tracer of the accretion rate–conducted one month after the brightest detected NIR flare and in the middle of the flaring activity of 2019. We develop an innovative light-curve extraction technique which (together with ALMA’s excellent sensitivity) allows us to obtain light curves that are simultaneously of high time resolution (2 s) and high signal-to-noise ratio (∼500). We construct an accurate intrinsic structure function of the Sgr A* submm variability, improving on previous studies by about two orders of magnitude in timescale and one order of magnitude in sensitivity. We compare the 2019 June variability behavior with that of 2001–2017 and suggest that the most likely cause of the bright NIR flares is magnetic reconnection.
Observational Kinematic Characteristics of Blobs in Solar Coronal Helmet and Pseudo Streamers
Authors: Lee Jae-Ok , Cho Kyung-Suk , An Junmo , Lee Hwanhee , Seough Jungjoon , Kim Yeon-Han , Kumar Pankaj
Published: October 2021

We examine two helmet and two pseudo streamers (HSs and PSs) observed on 2018 and 2019. The HSs (PSs) have dark coronal cavities and stretched loop structures (twin coronal cavities and narrow plasma sheet) at their bases, which are well observed in K-Coronagraph (K-Cor). Their outer-corona structures (top of core, cusp, and stalk) are also clearly identified in LASCO-C2. By investigating LASCO-C2 images, we find the following characteristics. (1) Blobs persistently move outward along the centers of HSs and PSs as well as their legs until the base of a stalk. We also detect outward-moving blobs along their outsides. (2) Blobs along the HS centers formed below tops of cores (∼2.6 R
⊙), while the other HS and PS blobs might be generated below 2.0 R
⊙. (3) HS blob speeds are generally similar to or smaller than the solar wind speed based on Parker’s model, while PS ones are larger. (4) HS (PS) blob speeds along the streamer centers are slightly smaller (larger) than those along the streamer legs, might be explained by the expansion-factor model. The blob speeds inside streamer structures (centers and legs) are larger than outside ones closer to solar equator, similar to typical solar wind speed distributions at solar minimum. (5) Several blobs along the HS centers only show sudden speed jumps at streamer cusps. These might be caused by sunward tension forces of overlying stretched closed fields and/or bidirectional outflows by magnetic reconnections in the cusps.
Are Delayed Radio Flares Common in Tidal Disruption Events? The Case of the TDE iPTF 16fnl
Authors: Horesh Assaf , Sfaradi Itai , Fender Rob , Green David A. , Williams David R. A. , Bright Joe S.
Published: October 2021

Radio emission from tidal disruption events (TDEs) originates from an interaction of an outflow with the super-massive black hole (SMBH) circumnuclear material (CNM). In turn, this radio emission can be used to probe properties of both the outflow launched at the event and the CNM. Until recently, radio emission was detected only for a relatively small number of events. While the observed radio emission pointed to either relativistic or sub-relativistic outflows of different nature, it also indicated that the outflow has been launched shortly after stellar disruption. Recently, however, delayed radio flares, several months and years after stellar disruption, were reported in the case of the TDE ASASSN-15oi. These delayed flares suggest a delay in the launching of outflows and thus may provide new insights into SMBH accretion physics. Here, we present a new radio data set of another TDE, iPTF 16fnl, and discuss the possibility that a delayed radio flare also has been observed in this case, ∼5 months after optical discovery, suggesting that this phenomenon may be common in TDEs. Unlike ASASSN-15oi, the data for iPTF 16fnl is sparse and the delayed radio flare can be explained by several alternative models: among them are a complex varying CNM density structure and a delayed outflow ejection.
Signatures of a Distant Planet on the Inclination Distribution of the Detached Kuiper Belt
Authors: Anderson Kalee E. , Kaib Nathan A.
Published: October 2021

A distant, massive planet in the outer solar system has recently been proposed to explain some observed features of extreme trans-Neptunian objects (TNOs). Here we use N-body simulations of the formation of the Kuiper Belt and Oort cloud as well as a survey simulator to compare models of the solar system with and without a ninth planet to one another as well as to observations. The main mechanism for TNOs to be deposited into the distant (a > 50 au), detached (q > 40 au) region of the Kuiper Belt in the eight-planet model is Kozai–Lidov oscillation of objects in mean motion resonances (MMR) with Neptune. This effect does not deposit low-inclination (i ≲ 20°) objects into this region. However, we find that the ninth planet generates a group of distant, detached TNOs at low inclinations that are not present in the eight-planet model. This disparity between the eight-planet and nine-planet models could provide a strong constraint on a possible planet nine with further detections of TNOs in the distant, detached region of the Kuiper Belt.
Void Replenishment: How Voids Accrete Matter Over Cosmic History
Authors: Vallés-Pérez David , Quilis Vicent , Planelles Susana
Published: October 2021

Cosmic voids are underdense regions filling up most of the volume in the universe. They are expected to emerge in regions comprising negative initial density fluctuations, and subsequently expand as the matter around them collapses and forms walls, filaments, and clusters. We report results from the analysis of a cosmological simulation specially designed to accurately describe low-density regions, such as cosmic voids. Contrary to the common expectation, we find that voids also experience significant mass inflows over cosmic history. On average, 10% of the mass of voids in the sample at z ∼ 0 is accreted from overdense regions, reaching values beyond 35% for a significant fraction of voids. More than half of the mass entering the voids lingers on periods of time ∼10 Gyr well inside them, reaching inner radii. This would imply that part of the gas lying inside voids at a given time proceeds from overdense regions (e.g., clusters or filaments), where it could have been preprocessed, thus challenging the scenario of galaxy formation in voids, and dissenting from the idea of them being pristine environments.
Why Do M Dwarfs Have More Transiting Planets?
Authors: Mulders Gijs D. , Drążkowska Joanna , van der Marel Nienke , Ciesla Fred J. , Pascucci Ilaria
Published: October 2021

We propose a planet formation scenario to explain the elevated occurrence rates of transiting planets around M dwarfs compared to Sun-like stars discovered by Kepler. We use a pebble drift and accretion model to simulate the growth of planet cores inside and outside of the snow line. A smaller pebble size interior to the snow line delays the growth of super-Earths, allowing giant planet cores in the outer disk to form first. When those giant planets reach pebble isolation mass they cut off the flow of pebbles to the inner disk and prevent the formation of close-in super-Earths. We apply this model to stars with masses between 0.1 and 2 M
⊙ and for a range of initial disk masses. We find that the masses of hot super-Earths and of cold giant planets are anticorrelated. The fraction of our simulations that form hot super-Earths is higher around lower-mass stars and matches the exoplanet occurrence rates from Kepler. The fraction of simulations forming cold giant planets is consistent with the stellar mass dependence from radial-velocity surveys. A key testable prediction of the pebble accretion hypothesis is that the occurrence rates of super-Earths should decrease again for M dwarfs near the substellar boundary like Trappist-1.
Formation of Polar Terrestrial Circumbinary Planets
Authors: Childs Anna C. , Martin Rebecca G.
Published: October 2021

All circumbinary planets (CBPs) currently detected are in orbits that are almost coplanar to the binary orbit. While misaligned CBPs are more difficult to detect, observations of polar-aligned circumbinary gas and debris disks around eccentric binaries suggest that polar planet formation may be possible. A polar-aligned planet has a stable orbit that is inclined by 90° to the orbital plane of the binary with an angular momentum vector that is aligned to the binary eccentricity vector. With n-body simulations we model polar terrestrial planet formation using hydrodynamic gas disk simulations to motivate the initial particle distribution. Terrestrial planet formation around an eccentric binary is more likely in a polar alignment than in a coplanar alignment. Similar planetary systems form in a polar alignment around an eccentric binary and a coplanar alignment around a circular binary. The polar planetary systems are stable even with the effects of general relativity. Planetary orbits around an eccentric binary exhibit tilt and eccentricity oscillations at all inclinations; however, the oscillations are larger in the coplanar case than the polar case. We suggest that polar-aligned terrestrial planets will be found in the future.
A Multispecies Pseudoadiabat for Simulating Condensable-rich Exoplanet Atmospheres
Authors: Graham R. J. , Lichtenberg Tim , Boukrouche Ryan , Pierrehumbert Raymond T.
Published: October 2021

Central stages in the evolution of rocky, potentially habitable planets may play out under atmospheric conditions with a large inventory of nondilute condensable components. Variations in condensate retention and accompanying changes in local lapse rate may substantially affect planetary climate and surface conditions, but there is currently no general theory to effectively describe such atmospheres. In this article, expanding on the work by Li et al., we generalize the single-component moist pseudoadiabat derivation in Pierrehumbert to allow for multiple condensing components of arbitrary diluteness and retained condensate fraction. The introduction of a freely tunable retained condensate fraction allows for a flexible, self-consistent treatment of atmospheres with nondilute condensable components. To test the pseudoadiabat’s capabilities for simulating a diverse range of climates, we apply the formula to planetary atmospheres with compositions, surface pressures, and temperatures representing important stages with condensable-rich atmospheres in the evolution of terrestrial planets: a magma ocean planet in a runaway greenhouse state; a post-impact, late-veneer-analog planet with a complex atmospheric composition; and an Archean Earth-like planet near the outer edge of the classical circumstellar habitable zone. We find that variations in the retention of multiple nondilute condensable species can significantly affect the lapse rate and in turn outgoing radiation and the spectral signatures of planetary atmospheres. The presented formulation allows for a more comprehensive treatment of the climate evolution of rocky exoplanets and early Earth analogs.

Authors: Hussein Nouran , El Refai Dina A. , Atef Alian Ghada
Published: October 2021

Abstract
AIM: The aim of this study was to compare the remineralization ability, ion release, microshear bond strength and wear resistance of a claimed bioactive restorative material (ACTIVA BioACTIVE Restorative, Pulpdent Corporation, Watertown, USA) with the conventional resin composite (​Filtek Z350 XT, 3M ESPE Elipar, Germany).
MATERIALS AND METHODS: The remineralization ability was evaluated after 28 days using Energy Dispersive X-Ray (EDX) analysis. Ion release was investigated at three-time intervals: 1, 14 and 28 days. Calcium and phosphate ions release were determined by using ion chromatography system. Microshear bond strength was assessed using Universal Testing Machine. A wear test was conducted using a dual axis chewing simulator.
RESULTS: ACTIVA™ was found to induce remineralization to the demineralized dentin. Results revealed that ACTIVA™ released Ca2+ and PO4-3 ions, whilst Filtek Z350 XT did not. Concerning microshear bond strength ACTIVA™ without adhesive application showed unacceptable failure. Regarding wear resistance there was no statistically significant difference between them.
CONCLUSION: ACTIVA™ bioactive restorative material seems promising bioactive restorative materials. Clinical trials are recommended to compare clinical performance of ACTIVA™ with the other restorative materials.

Authors: Elsherbini Ahmed N. , Niedermeier Wilhelm
Published: October 2021

Aim: Aim of this study was the evaluate the retention and biting force of conventional complete denture and after placement of a single implant in the mandible for an implant retained over-denture
Material and methods
Eight completely edentulous patients were selected. A single implant was inserted at the symphysis of the mandible and left to osseointergrate. During the osseointegration period a conventional complete denture was fabricated and inserted. Retention and biting force was measured at insertion and after 3 months of service. After osseointegration attachment was connected, space was formed in the fitting surface of the existing mandibular denture and retention silicon was placed. Retention and biting force were measured at insertion and after 3 months follow-up. Data were collected and statistically analyzed.
Results:
The retention mean values for the complete denture was 2.420±0.360, however the retention mean values for the single implant over-denture was 6.395±0.289.  F=3.80 with statically significance difference between the groups of P <0.01. The biting force mean values for the complete denture was 52.62±2.71, however the biting force mean values for single implant over-denture was 71.45±2.73. F= 1.790 with statically insignificance difference between the groups of P >0.01
Conclusion:
Single implant overdenture improved the retention and the biting force when compared with the complete denture, this has improved the quality of life and happiness.

Published: October 2021

BACKGROUND: Hyaluronic acid (HA) was explored as a powerful positive biocompatible material that participates in numerous biological processes related to morphogenesis and tissue healing. AIM: In this context, we elevated in this pilot study the effect of HA on soft tissue healing and bone repair of dental sockets (DS) as well as the postoperative pain. MATERIALS AND METHODS: Ten individuals of both genders (80% females and 20% males) with age range 18–44 years, were included who were diagnosed with two non-restorable teeth (total sockets n = 20). A split-mouth study design was performed where the DS of each patient were divided into Group A (study group): Topical oral HA gel (Gengigel®) was applied into sockets while Group B (control group): Sockets were left untreated. Study variables were evaluated including socket length, socket healing scores (healing index), and post-operative pain in both groups at day 1, 5, and 10 for each patient. RESULTS: There were no statistically significant differences between the control and study groups regarding the reduction of the socket length and postoperative complications but results revealed that HA enhances and fasten the healing capacity. CONCLUSION: HA can be used as adjunctive treatment to improve the wound healing process.

Published: October 2021

There have been several recent checklists, books and publications about Indian moths; however, much of this work has focused on biodiversity hotspots such as North-east India, Western Ghats and Western Himalayas. There is a lack of published literature on urban centres in India, despite the increased need to monitor insects at sites with high levels of human disturbance. In this study, we examine the moths of Delhi, the national capital region of India, one of the fastest growing mega-metropolitan cities. We present a comprehensive checklist of 338 moths species using 8 years of light trapping data (2012-2020) and examining about 2000 specimens from historical collections at the National Pusa Collection of ICAR-Indian Agricultural Research Institute, New Delhi (NPC-IARI) spanning over 100 years (1907-2020). The checklist comprises moths from 32 families spanning 14 superfamilies with Noctuoidea (48.5%) and Pyraloidea (20.4%) being the the two most dominant superfamilies. We provide links to images of live individuals and pinned specimens for all moths and provide detailed distribution records and an updated taxonomic treatment.

This is the first comprehensive annotated checklist of the moths of Delhi. The present study adds 234 species to the biodiversity of moths from Delhi that were not reported previously, along with illustrations for 195 species.
Critical media literacy to improve students' competencies
Authors: Mesquita-Romero Walter-Antonio , Fernández-Morante Carmen , Cebreiro-López Beatriz
Published: October 2021

Media literacy training is an urgent need of our time. Educational institutions must stand as fundamental domains to collectively address reflection on digital and media environments and prepare school-age citizens to constructively deal with the impact of the media. To do so, a paradigm shift to approach the issue is required: a critical awareness of the new scenarios created by the media and a broad reflection on their characteristics. A new framework where the spotlight is on the media, the surrounding environment is an essential reference point and training proposals are based on results and evidence. This study is part of a Design-Based Research, aimed at the creation, implementation and evaluation of a Critical Media Literacy program for high school students at the Escuela Normal Superior del Putumayo (Colombia). In this paper we present the results obtained by applying the Alfamed media competence "pre" and "post" questionnaire to the students participating in the program. The results obtained show a significant improvement both in the overall level of students' media competence and in four of the six dimensions that make up the theoretical reference model ("Technology", "Language", "Ideology and Values" and "Production and Dissemination").

La formación en las competencias mediáticas constituye una necesidad urgente en nuestra época. La escuela debe posicionarse como un entorno fundamental donde abordar de manera colectiva la reflexión sobre los entornos digitales y mediáticos y la preparación de los ciudadanos en edad escolar para afrontar de forma constructiva el impacto de los medios. Para ello, se impone un cambio de paradigma en el abordaje de la cuestión: una conciencia crítica ante los nuevos escenarios que crean los medios y una reflexión amplia sobre sus características. Un nuevo marco en el que lo mediático se torne central, el entorno próximo sea un referente imprescindible y las propuestas formativas se apoyen en resultados y evidencias. El trabajo que se presenta es una parte de una Investigación Basada en Diseño, orientada a la creación, implementación y evaluación de un programa de Alfabetización Mediática Crítica para el alumnado de bachillerato de la Escuela Normal Superior del Putumayo (Colombia). Se presentan los resultados obtenidos mediante la aplicación “pre” y “post” del cuestionario de competencias mediáticas Alfamed al alumnado participante en el programa. Los resultados obtenidos muestran una mejora significativa tanto en el nivel global de competencia mediática del alumnado, como en cuatro de las seis dimensiones que configuran el modelo teórico de referencia en el que se apoya el estudio (“Tecnología”, “Lenguaje”, “Ideología y Valores” y “Producción y difusión”).
Disinformation and multiliteracy: A systematic review of the literature
Authors: Valverde-Berrocoso Jesús , González-Fernández Alberto , Acevedo-Borrega Jesús
Published: October 2021

Disinformation is a serious problem for democratic systems in open societies. It is a global phenomenon that must be studied from different approaches and the educational dimension is one of the most relevant. It is necessary to know what educational models have been developed to empower citizens against disinformation. A systematic review of the literature (2011-2020), following the PRISMA protocol, was carried out by analyzing articles (n=76) extracted from three databases (Wos, Scopus and ERIC). Reference management and text mining software was used to data analyse. Eight research questions were answered on the conceptual framework, bibliometrics characteristics and pedagogical dimension. From the results of the content analysis emerges a vision of the role of multiliteracies in educational research and the problem of disinformation: media and information literacies are the most relevant and news and data literacies are incorporated. The need to adopt interdisciplinary approaches is confirmed. From the results of the educational dimension, three pedagogical approaches are identified: strategies for competencies development; focused on content and education for citizenship. Workshops and lesson plans are the most common teaching practices. The development of critical thinking, experiences in the co-construction of knowledge, and the values of civic education are fundamental against disinformation.

El problema de la desinformación es una amenaza para los sistemas democráticos. Es un fenómeno global que debe ser abordado desde múltiples perspectivas, siendo la pedagógica una de las más relevantes y, por ello, es necesario conocer qué modelos didácticos se han desarrollado para empoderar a la ciudadanía ante la desinformación. Se llevó a cabo una revisión sistemática de la literatura (2011-2020) bajo el protocolo PRISMA y se analizaron artículos de investigación (n=76) extraídos de tres bases de datos (Wos, Scopus y ERIC). El análisis fue realizado con apoyo de gestores bibliográficos y de minería de textos. Se da respuesta a ocho preguntas de investigación sobre el marco conceptual, las características documentales y la dimensión pedagógica. El análisis documental ofrece una visión del papel de las alfabetizaciones múltiples en la investigación educativa sobre el fenómeno de la desinformación, destacando la relevancia de la «alfabetización mediática» y la «informacional», así como la emergencia de la «alfabetización en noticias» y en «datos». Se evidencia la necesidad de adoptar enfoques interdisciplinares. Con relación a los resultados educativos, se identifican tres enfoques pedagógicos: estrategias competenciales, centrado en contenidos y educación para la ciudadanía. Las prácticas de enseñanza más frecuentes son la realización de talleres y el diseño de programaciones didácticas. El desarrollo del pensamiento crítico, las experiencias en co-construcción de conocimientos y los valores de la educación cívica son fundamentales contra la desinformación.
Les blueswomen contre le patriarcat
Authors: Davis Angela , Bordier Julien
Published: October 2021

Angela Davis, militante communiste africaine-américaine et membre du Black Panther Party, est aujourd’hui professeure de philosophie à l’université de Santa Cruz. Nous sommes reconnaissants aux éditions Libertalia et à son traducteur Julien Bordier de nous autoriser à publier un extrait de son livre majeur bientôt republié en poche, Blues et féminisme noir , paru pour la première fois en anglais en 1999. Ce livre est passionnant à plus d’un titre, notamment comme positionnement vis-à-vis de la manière dont les intellectuels interprètent le blues et les musiques qui en sont issues — en séparant souvent le sens des paroles du style de chant, ou en y lisant à tort le reflet direct, sans élaboration, de l’expérience noire. Mais ce qui nous a intéressés dans l’extrait de chapitre que nous reproduisons dans ce numéro, c’est la façon dont il reprend le fil d’une conversation qui court à travers nos précédentes publications d’articles de Mark Fisher et Ellen Willis, et dans une moindre mesure les allusions de Wayne Marshall, dans ce numéro, à la réception des références au sexe dans le reggaeton. L’enjeu de cette discussion, c’est de savoir comment les chansons indexent, à la fois explicitement et indirectement, ce qu’il advient des relations hommes-femmes, du sentiment amoureux et des institutions comme le mariage quand ils se construisent sous les conditions du capitalisme (à travers la dépendance directe ou indirecte au travail salarié), du patriarcat (notamment les différents types de violence faites aux femmes) et de l’héritage de l’esclavage (entendu comme une histoire d’exploitation, de coercition et de violence que l’abolition n’a pas annulée). Plus précisément, ce texte propose d’écouter autrement des chansons qui sont souvent perçues comme incarnant un discours de soumission ou (à l’inverse) comme obscènes. Cette histoire peut ainsi éclairer, à près d’un siècle d’écart, un morceau (et un clip) comme « WAP » de Cardi B & Megan Thee Stallion, ainsi que les multiples réactions qu’il a suscitées.

Les procédures contre des fonctionnaires de police pour coups et blessures par un dépositaire de l’autorité publique sont fréquemment classées sans suites pour absence de charges suffisantes et ne font que très rarement l’objet d’un procès. La pratique judiciaire se distingue par un faible taux de condamnation. Partant de ces statistiques officielles du contrôle de la criminalité, le projet de recherche aborde pour la première fois méthodiquement la question sous l’angle des personnes ayant subi ces violences en Allemagne, et étudie les facteurs situationnels et individuels de la victimation comme de son traitement judiciaire. Outre les affaires recensées par la statistique, il s’intéresse avant tout au chiffre noir de ce type d’infraction. Le présent article esquisse l’approche méthodologique de l’étude et analyse la stratégie de recrutement des participant·e·s à l’enquête – au moyen d’un effet boule de neige via des gatekeepers et d’une utilisation intensive des réseaux sociaux. Il examine et évalue les défis méthodologiques posés par le projet de recherche et donne un aperçu des premiers résultats.
Dynamiques et limites d’une restauration militaire autoritaire
Authors: Haddad Saïd
Published: October 2021

Dix ans après la chute de la Jamahiriya, le régime instauré par Mouammar Kadhafi, la Libye est confrontée à une fragmentation politique et sécuritaire. Déchirée entre deux entités politico-militaires et par une insécurité protéiforme, la Libye se trouve dans une configuration où l’exercice de la violence et son monopole sont l’objet d’une lutte entre prétendants au pouvoir. C’est dans ce contexte d’échec de la transition politique que l’option d’une solution militaire et autoritaire a émergé, nourrie à la fois par des dynamiques internes et externes qui s’articulent et par ce qui se passe dans une partie du monde arabe. L’objet de cet article est, à la lumière des dix années post-Kadhafi, de se pencher sur la construction politique de la solution militaire et autoritaire et d’en souligner les dynamiques et les limites.
La lutte des Amazighs en Libye pour la reconnaissance de l’amazighité
Authors: Ferkal Masin
Published: October 2021

Alors qu’ils étaient donnés pour une minorité en voie de disparition, les Amazighs de Libye ont joué un rôle important lors de la révolte contre le régime de Kadhafi en 2011. Ils ont également su mettre en avant leur identité amazighe et exiger sa reconnaissance. La situation instable que traverse la Libye notamment depuis 2014 n’a pas entamé la volonté et la détermination des Amazighs qui n’ont pas renoncé à des droits qu’ils considèrent naturels et légitimes. C’est leur attitude et leur(s) lutte(s), dans un contexte marqué par des luttes de clans et une guerre civile ayant plongé la Libye dans le chaos, qui sont passées en revue dans cet article. De la naissance de divergences, principalement suite à la publication par le CNT du projet constitutionnel en août 2011, à l’annonce du rejet total du projet de Constitution et de la décision de la mise en place d’une quatrième région administrative en janvier 2021, c’est principalement à travers l’action et les positions du Congrès national des Amazighs de Libye (CNAL) puis le Haut conseil des Amazighs de Libye (HCAL), qui lui a succédé, que la lutte des Amazighs pour la reconnaissance de leurs droits est analysée dans cette étude.

Cet article analyse le rôle de la Libye dans les conflits du Sahel. Il constate qu’avec l’effondrement de sa production pétrolière et des prix du baril Tripoli n’a plus les moyens de ses ambitions. Alors que le pays est lui-même en proie à la guerre, l’influence de la Libye s’exerce surtout par défaut d’État. Elle n’a plus rien à voir avec la politique agressive et messianique de Kadhafi, quand le « Guide de la Révolution » envoyait ses troupes annexer le nord du Tchad et occuper la capitale Ndjamena.
The “Cairé” and “The Ghost of Komat” Textual Landscapes and Cultural Heritage in Argentinean and Slovenian Folktales
Authors: Maria Palleiro
Published: October 2021

The present article proposes a comparative approach to Argentinean and Slovenian tales that share thematic features with ATU 326 (“The youth who wanted to learn what fear is”) from the standpoint of the fictional construction of verbal landscapes. The comparison is oriented to identifying similar narrative patterns dealing not only with thematic tale types but also with structural and stylistic features, along with changing details. The thematic, structural, and stylistic features common to different versions conform to a narrative matrix, which acts as a pretext to be recreated in diverse narrative contexts. The changing details give new meanings to universal pattern connected with the cultural heritage of different local contexts, such as the Argentinean and the Slovenian ones.
Народная демонология Полесья в контексте восточнославянских традиционных верований
Authors: Ľudmila N. Vinogradova
Published: October 2021

This article studies folk demonological beliefs that are widespread on the territory of Polesye, located on the border of Ukraine, Belarus, and Russia. The traditional culture of this region is of great interest for ethnologists of the broadest profile, since it preserves many archaic elements of all-Slavic significance. In the first part of the study, two blocks of the regional mythological system were considered: spirits of domestic and natural loci, and a group of characters originated from the souls of deceased. The second part of the work considers two groups of mythological characters: spirits not assigned to a specific locus (the devil, spirits of diseases, personification of death, characters for intimidation of children) and different categories of living people endowed with supernatural knowledge (witches, sorcerers, healers, werewolves). The study is based on data from the East-Slavic demonology.

18F-fluorodeoxyglucose positron emission tomography/computed tomography (18-FDG-PET/CT) is a functional imaging technique which is an established tool in oncology, and has also demonstrated a role in the field of inflammatory diseases, such as large vessel vasculitis (LVV). In the last few years, it is known that atherosclerotic lesions with inflammation, detected by FDG-PET, are high-risk structural features and more likely to lead to subsequent progression of atherosclerosis with more clinical complications.
Psoriasiform syphilis: a challenge
Authors: Schettini Antônio Pedro , Sardinha José Carlos , Marques Elyana Almeida , Massone Cesare
Published: October 2021

Syphilis is one of the greatest masqueraders in dermatology, like mycosis fungoides or sarcoidosis. In fact, secondary syphilis can simulate different dermatological conditions, not only clinically but also histopathologically. A 34-year old Brazilian man from Manaus (Amazonas) attended our Department complaining for 2 weeks of asthenia, weight loss and multiple asymptomatic disseminated erythematous papules and scaly plaques with well-defined borders and a tendency to confluence were observed on the trunk, neck and extremities, clinically similar to psoriasis guttata. The skin biopsy and laboratory tests disclosed secondary syphilis and the patient was treated with intramuscular benzathine penicillin with prednisolone, with a complete resolution. Psoriasiform syphilis, which imitates psoriasis, was well known by old dermatologists and was called syphilide psoriasiforme or psoriasis syphilitique. Psoriasiform syphilis is one of the atypical presentations of secondary syphilis and dermatologists should be aware of psoriasiform syphilis in order not to improperly treat syphilis patients with immunosuppressive drugs; also, pathologists should be aware of secondary syphilis histopathological features.
Uranium, thorium, and potassium analyses using pXRF spectrometry

Published: October 2021

The application of portable XRF spectrometry (pXRF) for determining concentrations of uranium (U), thorium (Th) and potassium (K) was evaluated using a combination of 12 Certified Reference Materials, 17 Standard Reference Materials, and 25 rock samples collected
from areas of known U occurrences or mineralization. Samples were analysed by pXRF in Soil, Mining Cu/Zn and Mining Ta/Hf modes. Resulting pXRF data were compared to published recommended values, obtained by total or near total digestion methods with ICP-MS and ICP-OES analysis.
Results for pXRF show a linear relationship, for thorium, potassium, and uranium (<5000 ppm U) as compared to the recommended concentrations. However, above 5000 ppm U, pXRF results show an exponential relationship with under reporting of pXRF concentrations compared to recommended
values. Accuracy of the data can be improved by post-analysis correction using linear regression equations for potassium and thorium, and samples with <5000 ppm uranium; an exponential correction curve is required at >5000 ppm U. In addition, pXRF analyses of samples with high
concentrations of uranium (e.g. >1 wt.% U) significantly over-estimated potassium contents as compared to the published values, indicating interference between the two elements not calibrated by the manufacturer software.

Background:

Increasing incidence of tuberculosis is intensifying the posttubercular obstructive airway disease (PTOAD) in developing countries. Currently, there are no standard treatment guidelines for the management of PTOAD patients. The present study aims to evaluate the prescribing pattern, adherence, adverse drug reactions (ADRs), and quality of life (QoL) in PTOAD patients.

Materials and Methods:

A prospective observational study was conducted to evaluate the prescriptions of PTOAD patients, estimating the medical adherence using Morisky 8-Item Medication Adherence Questionnaire, assessing ADRs using Hartwig's Severity Assessment Scale and assessing QoL using St. George's respiratory Questionnaire. Chi-square test, analysis of variance, paired t-test were used to compare the data. The significance of change in adherence status was assessed by Wilcoxon signed-rank test.

Results:

A total of 94 prescriptions of PTOAD were analyzed. Inhaled long-acting muscarinic antagonist was prescribed to 31.9% of patients. The most common inhaled fixed dose combination was long-acting beta-2 agonist with corticosteroid, prescribed to 52.1% of patients. At final follow-up, maximum percentage of patients were found to be highly adherent, i.e. 56.4%. Overall, 34% of patients have complained about mild category of ADRs. A significant improvement in QoL was observed. At baseline, mean forced expiratory volume in 1 (FEV1) was 64.66% ±23.61%, which increased significantly to 73.34% ±21.60% on final follow-up (P < 0.001).

Conclusion:

Bronchodilators are the mainstay of treatment of PTOAD patients, since both the QoL and FEV1 were improved with treatments. However, to have good treatment outcome, strict adherence along with safety of the medications must be assured.
Suffering and the portrait of YHWH in Jeremiah: energizing hope in contexts of suffering and pain
Authors: Igba J.T
Published: October 2021

This paper interrogates the portrait of YHWH that emerges in the face of the pain and suffering of Jeremiah and the covenant people of YHWH. The paper attends to the question through a combination of synchronic and canonical methods in reading the book of Jeremiah. Through a theological analysis and exposition of some key texts, which includes Jeremiah 8:18-9:3 11:18- 12:13; and 32:1-15, this paper demonstrates that the portrait of YHWH that emerges is not a God who watches the suffering of his covenant people helplessly, hardheartedly or dispassionately from without, but is himself grief-stricken in the suffering of his people, so that he might eventually bring suffering to an end and hold all that are complicit accountable. The paper discusses the call of Jeremiah in the light of its connotation of forthcoming suffering and pain and the non-insulation of the prophet and YHWH’s covenant people from the coming suffering. This is followed by an expose on the nature of the suffering of YHWH as portrayed by Jeremiah in his poetry of lament in 8:18-9:3 as well as the vital function of Jeremiah 32 in the suffering of YHWH’s people.

Passive discrete lens for broadband elastic guided wave focusing
Authors: Sadoulet-Reboul Emeline , Matten Gaël , Yi Kaijun , Ouisse Morvan
Published: October 2021

Elastic guided wave focusing is of great interest for applications such as vibroacoustic control, energy harvesting, or Structural Health Monitoring. Different strategies allow generation of this effect, GRadient-INdex devices in particular exploit medium with varying properties such as thickness to reproduce an adequate refractive index profile as in optics. The resulting continuous profiles have a curved geometry that can be hard to manufacture, and be difficult to integrate in a given design. The purpose of this paper is to propose a discrete design for a GRIN lens. It is composed of segments selected in number and thickness to give similar focusing effects as a continuous lens profile. The identified configuration is manufactured and bounded on an aluminium plate to evaluate the effective focusing performances. Numerical and experimental vibrometry results confirm that the proposed lens exhibits a fixed focal point over a broad frequency range. The discrete design overcomes fabrication issues encountered in continuous design, allowing for an easier integration in devices for elastic wave control.
