Published: September 2022

Objectives.The problem of developing a methodology for generating address sequences with a given switching activity and repeatability of addresses widely used in testing modern computing systems is being solved. The relevance of this problem lies in the fact that the main characteristic of the difference and their effectiveness for address sequences is the switching activity of both individual address bits and their sequences.Methods.Presented results are based on a universal method for generating quasi-random Sobol sequences, which are effectively used to generate targeted test sequences. As an initial mathematical model, a modification of the indicated generation method proposed by Antonov and Saleev is used. The main idea of proposed approach is based on the use of rectangular (m + k) × m generating matrices V of arbitrary rank r to generate address sequences.Results.The main properties of sequences generated in accordance with the new mathematical model are determined. A number of statements are given that substantiate the requirements for generator matrices to ensure the maximum period of generated sequences and the multiplicity of repetition of used addresses. The problem of synthesizing the sequences with given values of switching activity F(A) and F(ai) is solved. It is shown that in order to find a generating matrix for generating such sequences, it is necessary to solve the problem of decomposing an integer into terms. This decomposition represents the value of switching activity in the (m + k)-ary mixed number system, in which the weights of the digits are represented as powers of two from 20to 2m+k-1, and the values of the digits w(vi) lie in the range from 0 to m+k-1. On the basis of proposed restrictions, the notion of an integer decomposition diagram similar to the Young diagram is introduced, and the operation of its modification is defined.Conclusion.The proposed mathematical model expands the possibilities of generating test address sequences with the required values of switching activity of both test sets and their individual bits. The use of generating matrices of non-maximal rank makes it possible to formalize the method of generating address sequences with even repetition of addresses.
La inclusión educativa y atención a la diversidad en educación
Authors: Carrillo Vargas Carmita Marcela , Moscoso Jurado David Estuardo
Published: September 2022

En el Ecuador se han formulado diferentes programas, leyes o propuestas de ley, cuyo objetivo es incluir a todos los estudiantes dentro de un mismo escenario educativo. Las propuestas de inclusión y atención a la diversidad determinan que las personas tienen diferentes capacidades físicas, intelectuales, etcétera. Estas deben ser incorporadas por el docente, usando estrategias pedagógicas apropiadas en el aula de clases o durante los trabajos asincrónicos. La investigación se basa en un análisis sistémico bibliográfico, el cual ha permitido recabar información en artículos académicos que tiene relación con el tema a tratar. Entre los principales hallazgos encontrados se puede identificar que pese a existir una normativa vigente en relación a la inclusión y a la diversidad dentro de la educación, se vuelve compleja la aplicación de la ley, ya que un estudiante con necesidades especiales de educación requiere atención personalizada. Lo cual resulta imposible en instituciones públicas las cuales en promedio tienen treinta estudiantes o más por cada curso, otro factor importante es el apoyo que se puede tener desde los padres de familia, quienes en algunos casos no prestan la atención suficiente a sus representados por diferentes situaciones propias de la familia.
Investigation of Physicochemical Properties Properties and Specific Heat Capacity of Tio2 Doped- Polydimethylsiloxane Composites
Authors: EMRE Fatma Bilge
Published: September 2022

In this study, a series TiO2-doped–polydimethylsiloxane composite (PDMS-TiO2) were synthesized at constant amount of PDMS and different amount of TiO2 particles.  For this purpose, TiO2 structures were synthesized by the hydrothermal method. Morphology and chemical structure of the obtained TiO2 particles were investigated by scanning electron microscope (SEM), Energy Dispersive X-ray (EDX), X-ray diffraction (XRD) and Fourier transform infrared (FTIR) spectroscopy techniques. Prepared particles were directly dispersed in PDMS wax with melted. The obtained composite structures were examined structurally by SEM, FTIR, and XRD spectroscopy techniques. The intense peaks at 13° and 16.5° visible in the XRD spectrum confirm the desired composite structure. For the pure PDMS structure, 0,523 and 1,740 KeV was observed for O2 and Si in the EDX spectrum. Peaks at 0.452 (Ka) and 4.510 KeV (Kβ) were observed for the composite structures. Then, the thermal properties of the composite structures obtained were investigated by DSC analysis. The study of the specific heat capacity of obtained products is attained by using a DSC. Depending on the amount of doped TiO2 particles, the specific heat capacity value increased significantly in PDMS-TiO2 composite structures. Specific heat capacity study' of TiO2- polydimethylsiloxane composites is original and opened a new area about PDMS.

AHP Analysis on the Criteria and Sub-Criteria for the Selection of Fuel Cell Power Generation in Malaysia
Authors: Mohamad Faizal Ahmad Zaidi  , Shafini Mohd Shafie  , Mohd Kamarul Irwan Abdul Rahim
Published: September 2022

Malaysia is currently facing challenges in finding the right mix of energy sources for achieving sustainable energy supply. In term of fuel cell technology development, Malaysia is lacking the economic and infrastructure factors, besides local expertise, public perception, and industrial support. In fact, fuel cell technology at the present time is not being commercialized on a large scale in Malaysia. Due to much research is focused to the transportation sector, research on the other sectors, especially for power generation, is relatively lacking in Malaysia. For a start, this study aims to identify the criteria and sub-criteria for selecting the sources of fuel cell technology for power generation. An AHP analysis based on a group decision was performed and has found the impact on ecosystem (from environmental criterion), payback period, and investment cost (from economic criterion) are the most important sub-criteria for selecting the sources of power generation with fuel cell technology. This suggests that when it comes to renewable energy, the effect on environment will always come first in the mind. However, when it comes to the acquisition of fuel cell technology, no doubt that the economic factors are the main concern. This implies the focus should be on how to make the sources of fuel cell technology economical to justify its adoption. On the other hand, the less important criterion is technical, while the less important sub-criterion of technical is the technological maturity. However, this does not necessarily mean the technological factors are not important, but at the current stage of fuel cell technology development in Malaysia other issues seem to be more profound. For future study, few suggestions were made to improve the model.
Survival of Terrestrial N2–O2 Atmospheres in Violent XUV Environments through Efficient Atomic Line Radiative Cooling
Authors: Nakayama Akifumi , Ikoma Masahiro , Terada Naoki
Published: September 2022

Atmospheres play a crucial role in planetary habitability. Around M dwarfs and young Sun-like stars, planets receiving the same insolation as the present-day Earth are exposed to intense stellar X-rays and extreme-ultraviolet (XUV) radiation. This study explores the fundamental question of whether the atmosphere of present-day Earth could survive in such harsh XUV environments. Previous theoretical studies suggest that stellar XUV irradiation is sufficiently intense to remove such atmospheres completely on short timescales. In this study, we develop a new upper-atmospheric model and re-examine the thermal and hydrodynamic responses of the thermospheric structure of an Earth-like N2–O2 atmosphere, on an Earth-mass planet, to an increase in the XUV irradiation. Our model includes the effects of radiative cooling via electronic transitions of atoms and ions, known as atomic line cooling, in addition to the processes accounted for by previous models. We demonstrate that atomic line cooling dominates over the hydrodynamic effect at XUV irradiation levels greater than several times the present level of the Earth. Consequentially, the atmosphere’s structure is kept almost hydrostatic, and its escape remains sluggish even at XUV irradiation levels up to a thousand times that of the Earth at present. Our estimates for the Jeans escape rates of N2–O2 atmospheres suggest that these 1 bar atmospheres survive in early active phases of Sun-like stars. Even around active late M dwarfs, N2–O2 atmospheres could escape significant thermal loss on timescales of gigayears. These results give new insights into the habitability of terrestrial exoplanets and the Earth’s climate history.
Contribution of Spicules to Solar Coronal Emission
Authors: Sow Mondal Shanwlee , Klimchuk James A. , Sarkar Aveek
Published: September 2022

Recent high-resolution imaging and spectroscopic observations have generated renewed interest in spicules’ role in explaining the hot corona. Some studies suggest that some spicules, often classified as type II, may provide significant mass and energy to the corona. Here we use numerical simulations to investigate whether such spicules can produce the observed coronal emission without any additional coronal heating agent. Model spicules consisting of a cold body and hot tip are injected into the base of a warm (0.5 MK) equilibrium loop with different tip temperatures and injection velocities. Both piston- and pressure-driven shocks are produced. We find that the hot tip cools rapidly and disappears from coronal emission lines such as Fe xii 195 and Fe xiv 274. Prolonged hot emission is produced by preexisting loop material heated by the shock and by thermal conduction from the shock. However, the shapes and Doppler shifts of synthetic line profiles show significant discrepancies with observations. Furthermore, spatially and temporally averaged intensities are extremely low, suggesting that if the observed intensities from the quiet Sun and active regions were solely due to type II spicules, one to several orders of magnitude more spicules would be required than have been reported in the literature. This conclusion applies strictly to the ejected spicular material. We make no claims about emissions connected with waves or coronal currents that may be generated during the ejection process and heat the surrounding area.

We investigated the effect of magnetic fields on the collision process between dense molecular cores. We performed three-dimensional magnetohydrodynamic simulations of collisions between two self-gravitating cores using the Enzo adaptive mesh refinement code. The core was modeled as a stable isothermal Bonnor–Ebert (BE) sphere immersed in uniform magnetic fields. Collisions were characterized by the offset parameter b, Mach number of the initial core

The higher the magnetic field strength, the lower the accretion rate. For models with b = 0 and θ = 90°, the accretion rate was more dependent on the initial magnetic field strength compared with b = 0 and θ = 0° models. For off-center (b = 1) collisions, the higher specific angular momentum increased; therefore, the gas motion was complicated. In models with b = 1 and

Catastrophic Cooling in Superwinds. III. Nonequilibrium Photoionization
Authors: Danehkar A. , Oey M. S. , Gray W. J.
Published: September 2022

Observations of some starburst-driven galactic superwinds suggest that strong radiative cooling could play a key role in the nature of feedback and the formation of stars and molecular gas in star-forming galaxies. These catastrophically cooling superwinds are not adequately described by adiabatic fluid models, but they can be reproduced by incorporating nonequilibrium radiative cooling functions into the fluid model. In this work, we have employed the atomic and cooling module maihem implemented in the framework of the flash hydrodynamics code to simulate the formation of radiatively cooling superwinds as well as their corresponding nonequilibrium ionization (NEI) states for various outflow parameters, gas metallicities, and ambient densities. We employ the photoionization program cloudy to predict radiation- and density-bounded photoionization for these radiatively cooling superwinds, and we predict UV and optical line emission. Our nonequilibrium photoionization models built with the NEI states demonstrate the enhancement of C iv, especially in metal-rich, catastrophically cooling outflows, and O vi in metal-poor ones.

Published: September 2022

COVID-19 infection usually causes respiratory distress syndrome. Liver impairment has been reported, there is no clear mechanism for liver damage. Liver damage may be due to other factors, such as a viral infection or inflammations in the liver. Lack of information among the residents of the city of Najaf about the differences between males and females infected with the “Corona Virus” disease (“Covid-19”). In this study, we focus on the effects of (“COVID-19”) on liver physiology in 60 (“COVID-19”) patients (20-70 years old). Examinations, taking into account demographic information as well as clinical findings, show that the patient has liver abnormalities. The result indicated increasing of  liver enzymes ALT,AST,ALP and TBiL levels on patients with covid-19 Corona Virus.Males patients had a higher risk of liver enzymes level elevation than females. ("TBiL") concentrations were highly increased when compared with control.  In critical patients, severe liver cells abnormalities result from ("COVID-19"), which requires follow-up and immediate therapeutic intervention. Because of its strong relationship with the severity of  the injury in ("COVID-19"), ALT,AST,ALP, and TBiL it is expected to be of great importance in the future prediction and diagnosis of infection.
Omega-3 and Vitamin E Supplementation Effect on Reactive Oxygen Species and Placental Vascular Endothelial Growth Factor: Pre-eclampsia Model
Authors: Amir Arni , Darwin Eryati
Published: September 2022

BACKGROUND: Pre-eclampsia (PE) has been associated with oxidative stress and inflammation. Omega-3 fatty acids and vitamin E have beneficial function to maintain cell membrane, prevent oxidative stress, and inhibit the production of proinflammatory cytokines. The purpose of the study was to determine the effect of omega-3 and vitamin E supplement to Reactive Oxygen Species (ROS) and placental Vascular Endothelial Growth Factor (VEGF) on PE rats model.

AIM: This study aimed to investigate the effect of omega-3 and vitamin E supplementation on ROS and placental VEGF.

METHODS: This research has been carried out at animal house and Biomedical Laboratory of the Medical Faculty Andalas University. The design of this research was experimental study with post-test only control group design. Thirty pregnant rats were divided into five groups. Group K-without treatment, group K+ was given L-NAME, group P1 was given L-NAME + omega-3, group P2 was given L-NAME + vitamin E, and group P3 was given L-NAME + omega-3 + vitamin E. The L-NAME dose was 50 mg/kg/day. At the 19th day of gestation, the pregnancy was terminated and the blood serum was used for examination of ROS and placental tissue was collected for examination of VEGF using ELISA kit. The data were analyzed by one-way ANOVA and post hoc test Bonferoni.

RESULTS: The analysis results found that there were significant differences between omega-3 and vitamin E supplements on ROS levels and placental VEGF levels. Administration of omega-3 only or combination with vitamin E can effectively improve endothelial function by increasing the level of VEGF.

CONCLUSION: Omega-3 (DHA 120 mg, EPA 180 mg) and vitamin E (α-tocopherol 300 iu) supplement decreased ROS and increased placental VEGF on pre-eclampsia rats model.

Les pratiques pédagogiques qui soutiennent le développement de l’autodétermination des élèves ayant une déficience intellectuelle : regards d’enseignantes impliquées dans une communauté de pratique
Authors: Charette Catherine , Caouette Martin , Chatenoud Céline , Otis Ann-Sophie
Published: September 2022

En milieu éducatif, le développement de l’autodétermination est un levier au développement de la participation sociale des élèves (MEES, 2019). Afin de mieux accompagner les enseignants dans la mise en place de telles pratiques, il est important que ceux-ci soient formés et accompagnés (Berger, 2016 ; Cho  et al. , 2011 ; Shogren  et al. , 2014). C’est dans cette optique qu’une communauté de pratique a été mise sur pied dans un centre de services scolaire du Québec. Cet article présente les résultats d’une recherche visant à décrire les pratiques déclarées des enseignantes en soutien au développement de l’autodétermination de leurs élèves à la suite de leur participation à une communauté de pratique traitant du sujet. Les pratiques décrites par les enseignantes mettent en lumière le fait qu’elles doivent non seulement soutenir le développement de certaines capacités qui favorisent le développement de l’autodétermination de leurs élèves, mais qu’elles doivent aussi adopter des attitudes et une posture qui encouragent son développement. Le travail de collaboration entre collègues ainsi que la planification des activités en classe représentent également des leviers importants au soutien de l’autodétermination selon elles.
Les échanges entre pairs contribuent-ils à l’autodétermination des individus ? De quelles manières ?
Authors: Gardien Ève
Published: September 2022

Cet article propose d’explorer les liens entre démarche d’autodétermination et relation entre pairs. Appuyés sur les données issues d’une ethnographie au long terme de pratiques de soutien et d’accompagnement par les pairs, les processus sociocognitifs sous-tendus par les échanges d’expérience entre pairs seront explicités, ainsi que les effets des relations de pairité sur les individus y participant. Cette compréhension permettra alors de discuter comment ces processus sociaux et leurs effets peuvent ou non alimenter les quatre dimensions de l’autodétermination, à savoir : l’autonomie comportementale, l’autorégulation, l’empowerment psychologique et l’autoréalisation. Cette analyse permettra de conclure sur une contribution en positif des soutiens et accompagnements par les pairs aux démarches d’autodétermination, et de mieux appréhender les différentes modalités de ces apports.
L’éducation inclusive en danger au Brésil
Authors: Pinheiro Diogenes , Plaisance Éric , Prado Luiz Gustavo
Published: September 2022

Au Brésil, on constate actuellement un risque de recul des politiques éducatives inclusives. L’article trace un panorama historique de l’évolution de l’éducation des enfants en situation de handicap. L’éducation spéciale est une histoire ancienne, ancrée dès le XIX e  siècle dans le modèle français des instituts pour aveugles et pour sourds, puis développée au XX e  siècle par des médecins psychiatres et par des associations philanthropiques. À partir des années 1990, l’éducation pour tous marque une période d’émancipation et de progression des droits, amplifiée dans les années 2000 sous le référentiel global de l’inclusion. La tentative de retour au spécial ségrégatif est l’objet d’un décret présidentiel de 2020, mais de nombreuses luttes sociales y font obstacle, relayées par le Tribunal fédéral suprême qui y voit une mesure contraire à la Constitution.

Il questionne la place de l’école en prison et le rôle de l’enseignant, ainsi que les modalités et les formes de la contestation. L’article décrit ensuite la mise en place et les résultats de deux actions expérimentales visant à mettre au point des outils à destination des enseignants en milieu pénitentiaire. Ces outils ont pour objectif de favoriser une (ré)appropriation du savoir par les élèves détenus, et ainsi réduire la place de la contestation qui peut compromettre l’acquisition de savoirs.
Le mythe de l’autonomie stratégique : une perspective de l’extérieur sur la capacité des puissances d’agir seules
Authors: David George
Published: September 2022

La politique militaire de la France sous la V e  République est profondément ancrée dans le concept d’autonomie stratégique. La signification du terme dépend, cependant, du contexte, du locuteur, de l’usage et du moment. Basé sur l’usage et l’histoire du terme ainsi que sur les actions conséquentes, un observateur n’a pas d’autre choix que d’analyser la politique étrangère française selon la théorie réaliste, notamment parce que la France a donné pour instruction de le faire plusieurs fois. Paradoxalement, la France n’a pas le poids dans les instruments de puissance nationale pour se comporter comme un pays purement réaliste, même avec les armes nucléaires. Néanmoins, elle est puissante dans le monde occidental et démocratique ; c’est le moment historique de choisir une autre terminologie plus productive pour la politique militaire future.
Les armées face aux normes : opportunités ou contraintes ?
Authors: Borrel Géraldine
Published: September 2022

Les normes sont omniprésentes. Elles permettent les échanges, offrent un cadre et des règles sécurisant les activités dans les champs matériels et immatériels. Dans les armées, la norme est utile et souvent indispensable pour garantir la capacité à opérer en environnement complexe, au sein d’alliances par exemple. Aujourd’hui, l’instabilité et l’incertitude du contexte international, mais aussi l’émergence du numérique et la régulation des nouveaux espaces de conflictualité (cyber, Espace, informationnel, grands fonds marins…) invitent à s’interroger sur le choix des normes et la manière de préserver la capacité des armées à opérer dans les conditions extrêmes. Les normes sont-elles alors pour les armées, des opportunités ou des contraintes ?
La Direction générale de l’armement à l’ère des menaces hybrides
Authors: Louise Damien
Published: September 2022

Dans un contexte avéré de menaces hybrides, l’action de la Direction générale de l’armement reste discrète. Pour autant, dans le cadre de ses rôles principaux (acquisition d’armements, intégration de l’innovation, soutien à l’export, structuration et protection de la base industrielle et technologique de défense), la DGA contribue à fournir à l’État, et en particulier aux forces armées, les moyens d’être plus résistant aux menaces hybrides. Il serait ainsi souhaitable qu’elle s’insère plus dans une communication stratégique sur les performances des armements français, oriente mieux ses efforts d’influence à l’étranger, et surtout mette en avant la coordination entre ses différents modes d’action et d’autres au sein du ministère.

De l’utilité de principes génériques d’organisation pour les armées ?
Authors: Morcel Valérie
Published: September 2022

Au sein de l’écosystème militaire, une variété importante d’organisations coexiste. Sédimentées au fil de l’Histoire ou créées récemment, elles reflètent la prise en compte des atouts et inconvénients de chacune des structures, la nécessité d’adopter des processus adaptés et l’énorme poids des relations humaines. Soumises aux influences de l’évolution de la conflictualité, des technologies et de la diffusion de l’information, elles doivent se conformer à des principes génériques : le respect de la finalité des armées et d’un équilibre cohérent entre diverses tentations antagonistes tout en réduisant au maximum les délais d’adaptation nécessaires pour faire face aux circonstances et à la transition entre les différents états stratégiques.

Published: September 2022

L’objectif du présent article est d’apprécier l’effet des TIC sur la compétitivité des IMF au Cameroun. Les données sont obtenues par questionnaire auprès de 88 IMFs. Nous avons eu recours à une analyse de classification, au test de comparaison de Kruskal-wallis, au test d’indépendance de Khi-2 et à la régression logistique multinomiale. Les résultats montrent que 56,8% des IMFs estiment avoir un niveau élevé de compétitivité. Par ailleurs, le nombre d’ordinateurs, le nombre de logiciels, le recours à intranet et l’utilisation du téléphone expliquent significativement la compétitivité des IMF au Cameroun.
Vers une évolution des facteurs d’adoption du modèle de coûts ABC au sein du secteur viti-vinicole ? Une étude qualitative à partir du projet Sustaincost
Authors: Jourdaine Marc , Trébucq Stéphane
Published: September 2022

La question de l’utilisation de la méthode de calcul de coûts ABC (Activity Based Coshing) est étudiée, dans la perspective de la mise en place d’un système de management intégrant, au sein des propriétés viti-vinicoles, les aspects financiers et environnementaux. La recherche réalisée permet de comprendre les facteurs jouant un rôle dans l’adoption d’une comptabilité d’activités. L’identification de ces facteurs s’appuie sur le modèle d’innovation de Rogers et son adaptation proposée par Alcouffe pour les outils de gestion. L’étude de cas retenue est celle d’un nouveau module ERP appelé Sustaincost, porté par la société Ertus Group. Elle permet de montrer la faiblesse des canaux de diffusion de la méthode. Toutefois, la mise en place d’un modèle sectoriel au travers d’un système informatique partagé, auquel peuvent s’ajouter des informations environnementales, est de nature à rendre l’adoption du modèle ABC plus attractive.

La théorie de la régulation sociale : une stakeholder theory à la francaise
Authors: Pourquier Catherine
Published: September 2022

Cet article montre en quoi la Théorie de la Régulation Sociale (TRS) est une Stakeholder theory (ST) à la française. En nous appuyant sur les travaux de Jean-Daniel Reynaud et R. Edward Freeman nous discutons dans cette étude conceptuelle deux concepts-clés communs à la TRS et à la ST : l’acteur/stakeholder et la légitimité, qui ouvrent la voie à un possible dialogue entre ces deux théories. Une fois ce dialogue ouvert, le recours au concept de Stakeholder Management permet un rattachement conceptuel de la TRS à la ST en la reliant directement à la Théorie des organisations. La régulation devient alors une forme particulière de gestion des tensions et des conflits organisationnels. Elle permet des passerelles culturelles entre les notions d’acteur et de stakeholder, d’intérêt ou de stake, de négociation et de coopération. Nous concluons cet article avec un modèle original qui illustre ce rattachement de la TRS à la ST.
To Whom Have We Been Talking? Naeem Mohaiemen’s Fabulation of a People-to-Come

This essay considers Naeem Mohaiemen’s three-channel video installation Two Meetings and a Funeral (2017) and performance-lecture The Shortest Speech (2019/2021) in order to expand the frameworks through which the Cold War might be understood from our contemporary perspective. It analyzes the technologies, techniques, and conventions of social assembly and public address embedded in and animating Mohaiemen’s works and makes visible the problematics of imagining a “people” during the Non-Aligned Movement’s historical context and in our neoliberal global capitalist present.
Das unsichtbare Visier – A 1970s Cold War Intelligence TV Series as a Fantasy of International and Intranational Empowerment; or, How East Germany Saved the World and West Germans Too
Authors: Amar Tarik Cyril
Published: September 2022

This article addresses a franchise of intelligence films in the former Communist East Germany. Under the general title Das unsichtbare Visier—The Invisible Visor—they were produced for television and very popular. In general, the Cold War East produced a rich array of its own intelligence heroes, which cannot be reduced to mere derivatives of Western models. Yet there were commonalities and interactions across Cold War divides. One of these common features that Visier shared with many intelligence films globally was the depiction of abroad as both an “invisible front” of dangers and temptations and an exciting realm of adventure and consumption. Visier could not but also be a fantasy about East German citizens encountering, withstanding, and also enjoying the dangers and temptations of the Western Cold War Other. This included their facing two peculiar challenges: a degree of international mobility unlike anything the vast majority of ordinary East Germans could experience and the West’s consumerism. Visier addressed both these issues through what we could describe as an essentially playful—and dis-playful—practical cosmopolitanism. A careful look reveals Visier as a rich artifact of Cold War popular culture, with complex messages. The image of the heroic East German agent included a running comment of compensatory wish fulfillment. Here were ideal East German citizens doing their duty and yet also getting a fair slice of the capitalist good life abroad that most of their compatriots could not reach. They also consistently punched above their weight vicariously for East Germany as a whole. Like Britain’s James Bond, these were agents of an at-best middling power doing major things in the world at large. And finally, perhaps most satisfyingly of all, they turned into gentle, benevolent guardian angels of hapless West German cousins, neatly reversing West Germany’s claims of superiority.

Alors que la surveillance numérique à distance de l’agriculture s’affirme dans les années 2000 comme un pilier majeur des nouvelles régulations environnementales du secteur, le Brésil offre l’exemple des capacités de l’agrobusiness à subvertir ces instruments à son profit. En décrivant le déploiement et les usages politiques du cadastre environnemental rural, nous montrons qu’au-delà d’objectifs de verdissement institutionnel à destination des marchés agricoles internationaux, cette plateforme en open data a été une pièce maîtresse pour l’agrobusiness national dans sa quête de marges de manœuvre vis-à-vis des ONG de conservation mais aussi des transnationales agro-industrielles. Cet article propose d’explorer ce que le numérique apporte aux acteurs dominants du monde agricole brésilien dans leur recherche d’autonomie sectorielle.
Mais où est donc passée l’éthique du care ?

En dépit d’une technicisation croissante du métier qui fait écho au processus de spécialisation du champ médical, la revendication d’autonomie des infirmier·es est principalement adossée au versant relationnel de leur travail, plaçant l’« approche globale » au cœur des discours professionnels. Dans quelle mesure les savoir-faire en matière de sollicitude des infirmier·es peuvent-ils cependant survivre face aux injonctions gestionnaires qui s’appliquent désormais à grand renfort d’outils informatiques s’immisçant dans la relation soigné·es/soignant·es ? Basé sur une enquête qualitative menée en Suisse romande auprès de vingt-neuf infirmières et infirmiers exerçant en oncologie, l’article montre que le non-abord de la sexualité est un révélateur saisissant des grandes difficultés que rencontrent les soignant·es pour faire reconnaître tout un pan de leur rôle professionnel se rapportant au travail du care, qui s’avère aussi peu rentable économiquement que symboliquement.

In this paper, the authors have emphasized on the perspectives of the Terahertz channel modeling in Internet of multimedia nano things (IoMNT) networks. A modulation technique targeting body-centric network is discussed. An analogy of a real Terahertz antenna is developed within a terahertz multi-layer modelling channel for a human skin tissue. As a result, the investigation of how signals at THz frequency band interact and transmit within the skin biomaterial. The human skin model used to collect data was selected to have four layers: epidermis, dermis, blood, and hypodermis, with the depth of the layers varying between normal human body values. It is revealed from the literature that the frequency and content have a substantial impact on path failure. The estimated path loss could thus differ considerably, but for a human skin model with depths of 0.21 mm, 1.23 mm, 1.38 mm, and 3.76 mm, the frequencies of 0.5-1.5 THz at the end distance resulted in a path loss estimated about 250-350 dB.

Interest in eVTOL air vehicles has increased significantly in recent years. Most development efforts for eVTOL aircraft have addressed conventional performance objectives. However, the acoustic noise remains a critical aspect that must be dealt with due to its significant impact on operations. This paper summarizes a study of eVTOL rotor acoustic noise variation using a CFD augmented comprehensive rotorcraft modeling and simulation tool combined with acoustic analysis that was validated against measured eVTOL drone rotor noise data. The paper presents a thorough parametric investigation of the variation of the rotor/propeller acoustic signature with emphasis on the broadband noise that often dominates in eVTOL rotor/propeller operation. The parametric study has investigated the effect of a range of rotor parameters, including number of rotor blades, rotor solidity, tip Mach number, blade planform (e.g., chord distribution), etc. The study has revealed important acoustic characteristics of eVTOL rotors. Several findings from the study are fundamentally unique to eVTOL rotors, which provide physical insight into supporting low noise eVTOL rotor/propeller design and development.

Published: September 2022

For small UAVs aeroacoustics predictions, an in-house acoustic code (ACUM) has been extended for broadband noise using empirical Brooks-Pope-Marcoloni (BPM) method. Then, the acoustic code is coupled with a comprehensive analysis tool (FLIGHTLAB) or Reynolds-Averaged Navier-Stokes (RANS) method to predict the noise from DJI 9443 CF rotor. The effect of two input parameters of BPM on the broadband noise was studied, which are effective angle of attack and boundary layer parameters. The empirical formula for the boundary layer parameters is replaced with predictions using two-dimensional RANS, which allows arbitrary airfoils other than NACA0012. The boundary layer parameters are predicted using three-dimensional RANS method to capture a three-dimensional flow effect which can be dominant on modern propeller designs operating at high rotational speeds. It was confirmed that the three-dimensional effect on boundary layer conflicted with BPM method because it was developed based on two-dimensional flow data base. Finally, higher frequency tonal noise was predicted from the unsteady three-dimensional RANS to be combined with BPM results. This results in improved noise spectra predictions at mid-range frequency.

A major barrier to certification and public acceptance of emerging distributed electric propulsion (DEP) aircraft is their noise. Like conventional helicopters, accurate noise prediction of DEP aircraft requires accurate modeling of realistic flight dynamics and controls. Furthermore, aspects unique to DEP aircraft must be modeled, such as variable rotor speed for thrust control, and unsteady aerodynamics arising from rotor thrust control and aerodynamic interactions between rotors and the airframe. To address these needs, this paper describes the development and software coupling of a noise prediction system for DEP aircraft. This system is demonstrated for maneuvering flight simulations consisting of a roll attitude doublet in low speed forward flight, for two rotor thrust control schemes: variable rotor speed and variable collective pitch. Loading noise levels for this configuration generally exceeded thickness noise levels. For a single rotor, loading noise modulated with thrust, regardless of the cause of the time variation of loading (variable rotor speed or collective pitch). However, the range of modulation was greater for the variable rotor speed case than for variable pitch. Less modulation is observed in the total noise for all rotors, because the rotor thrusts must vary to balance the aircraft. Interference patterns are observed for the constant speed case due to coherent phase relations between the rotors, whereas the noise of the variable speed rotors does not add coherently.
