Design and Implementation of a Vehicle Tracking Mechanism using Wireless Network Infrastructure
Authors: Esekhaigbe E. , Okoduwa E. O.
Published: May 2022

This study presents the design and implementation of a vehicle tracking system with the goal of assisting victims of road accidents in obtaining prompt assistance from the rescue team. This is accomplished by sending tracking data to the rescue team's mobile equipment. The system was developed utilising available electronics components, installed in a vehicle. Accident situations were recreated by dropping loads of different sizes from a height and loads linked to a rope to shatter the glass on the automobile in order to determine the minimal impart energy necessary to break the glass and the likelihood of a catastrophic accident. If an accident occurs, the GPS engine sends the coordinates of the crash site to the rescue team's mobile equipment through the SIM900 module's GSM engine over a GSM frequency for tracking. The system's tracking accuracy was determined using a standard GPS device, the GERMIN GPSMAP78s, to get the GPS coordinates of the scene and tracking them using the Google map API. When tracked using Google map, the tracking information obtained, when compared with the GARMIN GPSMAP78s, were exact, indicating that proposed device is capable of transmitting accurate tracking information in a short period of time, thereby saving lives.

Published: May 2022

The goal of this research was to remove iron oxide from Ibute-Nze kaolin by dissolving the clay mineral in an aqueous oxalic acid solution and optimizing the process. The chemical composition of the raw and modified clay was determined using x-ray fluorescence, and the morphology of the solid sample was determined using a scanning electron microscope. The best conditions for the oxalic acid leaching of iron-oxides impurity from Ibute-Nze kaolin were determined using response surface methodology based on Box-Behnken design. The studies were carried out within the following process parameter ranges: 40–90 leaching temperature; 0.075-0.355mm particle size; 1–6 mol/dm3 acid concentration; 0.02–0.12 g/cm3 kaolin sample to acid ratio and 30-240 min contact time. The characterization revealed that Ibute-Nze clay is kaolinitic in nature and calcination at 750 opens more pores for its leaching. According to the analysis of variance, a second-order polynomial regression equation provided the best fitting for the experimental data. The predicted and experimental response values were shown to be correlated (R2 = 0.9276) in the experimental runs. The following were found to be the best conditions for the leaching process variables: 83.2051 leaching temperature, 0.0827mm particle size, 3.6179mol/dm3 acid concentration; 0.0287g/cm3 kaolin to acid ratio and 217.932min reaction time. The chemical leaching process was 92.6035 per cent under these conditions, which made the clay good for industrial applications.
Antibacterial Approach Of Lactobacillus Species Isolated From Exterior Of Fruits
Authors: Shireen Farah
Published: May 2022

Probiotics are important to guarantee the food production of many people all over the world, particularly those who are oppressed and highly susceptible. Some of this will be enhanced by increasing the number of natural resources that can be used to make consumable food products and minimizing generally pro components to generate food that is safe to eat and rich in nutrients. Lactobacillus, a carboxylic acid bacterium, was isolated primarily from decaying vegetables, fruits, and room trash. Genus Lactobacillus belong cluster of carboxylic bacterium that is represented as a gaggle of heterogeneous, regular non-spore-forming, gram-positive rods that have numerous habitats like plants and duct tracts and throughout the surroundings. Lactobacilli strains, often known as probiotics, are beneficial bacteria that improve digestion, combat disease, and promote digestion in humans and animals. Some species like true bacteria Plantarum, true bacteria casei, and true bacteria bulgaricus are typically isolated from farm. A natural protection exists in a number of fruits. Organic acids in fruits are sufficient to generate a pH of four or lower on the pH scale. The most essential determinant in defining the dominant microflora in fruits is the pH scale, and consequently the type of acid. A pH scale cannot support the growth of food-borne bacteria that are harmful to human health. The carboxylic acid bacterium performs a critical role in protecting the host against hazardous pathogens while also strengthening the system. Carboxylic acid bacteria are great sources of probiotics with potential qualities that, when administered in sufficient levels, can benefit the host's health.

Authors: Ríos T. Rosalin P. , Carreira María B.
Published: May 2022

La pandemia de COVID-19 ha impactado mundialmente las distintas esferas del funcionamiento de la sociedad, siendo la salud mental una de ellas. La pandemia y su impacto han sido reconocidos por entidades internacionales como la Organización de las Naciones Unidas (ONU, 2020) y la Organización Panamericana de la Salud (OPS, 2020). Cada día se han reportado nuevos contagios y pacientes recuperados de la enfermedad, pero que han tenido que lidiar con las consecuencias biopsicosociales relacionadas a la enfermedad, denominadas condiciones post COVID (Centers for Disease Control and Prevention [CDC], 2021). En los pacientes recuperados del COVID-19, una de las alteraciones descritas en la clínica corresponde a la salud mental, por lo que se han reportado estudios científicos recientes. Este estudio tuvo el objetivo de analizar investigaciones existentes sobre las alteraciones emocionales en pacientes recuperados de COVID-19, con la finalidad de reconocer el estado de salud mental de los individuos en etapa post COVID y de generar recomendaciones para el manejo psicoemocional de los recuperados de la enfermedad en Panamá. Se utilizó una investigación documental, diseño no experimental, mediante la búsqueda exhaustiva de investigaciones internacionales y latinoamericanas, en bases de datos científicos y de acceso abierto. Los resultados revelaron que la salud mental de los pacientes recuperados de COVID-19 ha sido afectada. La sintomatología ansiosa y de insomnio, así como los síntomas depresivos y de estrés postraumático fueron las alteraciones emocionales más frecuentes. Se enfatiza la monitorización y acciones preventivas como medidas para el manejo de las alteraciones de la salud mental post COVID.
Desarrollo y consolidación de los estudios regionales en España
Authors: Cuadrado-Roura Juan R.
Published: May 2022

Los problemas regionales y territoriales, en general, han ocupado con frecuencia una posición importante en las preocupaciones de los investigadores vinculados al ámbito de las ciencias sociales. Sin embargo, aunque pueden contabilizarse algunas aportaciones muy interesantes realizadas en el pasado, en España la investigación sobre los problemas regionales se inició, realmente, en la década de los sesenta del pasado siglo y su consolidación tuvo lugar en el período 1975 al 2000, como se expone en las secciones 2 y 3 de este artículo. Una nueva generación de economistas y geógrafos ha protagonizado el singular avance de este tipo de estudios en el país y su resultado ha sido la creciente presencia de autores españoles en las publicaciones, congresos, proyectos y otras actividades internacionales que, junto con su propia expansión interna, han situado la literatura en este campo a un nivel similar al de los países que son líderes a escala internacional. En la sección 4 hemos tratado de mostrar cuáles han sido los temas que han merecido especial atención en las últimas décadas y dónde se han producido más innovaciones. La sección 5 sugiere algunos nuevos temas de interés en los que pueden producirse avances, y una breve nota final subraya que hay razones para pensar que los progresos observados tendrán una clara continuidad en el futuro. En definitiva, el artículo pretende ofrecer una panorámica del desarrollo de los estudios regionales y urbanos en España

There is a small group of peculiar early-type stars on the main sequence that show different rotation velocities from different spectral lines. This inconsistency might be due to the binary nature of these objects. We aim to verify this hypothesis by a more detailed spectroscopic and photometric investigation of one such object: HD 183986. We obtained 151 high- and medium-resolution spectra that covered an anticipated long orbital period. There is clear evidence of the orbital motion of the primary component. We uncovered a very faint and broad spectrum of the secondary component. The corresponding SB2 orbital parameters, and the component spectra, were obtained by Fourier disentangling using the KOREL code. The component spectra were further modeled by iSpec code to arrive at the atmospheric quantities and the projected rotational velocities. We have proven that this object is a binary star with a period P = 1268.2(11) days, eccentricity e = 0.5728(20), and mass ratio q = 0.655. The primary component is a slowly rotating star (

A multiperiod photometric variability was detected in the TESS data ranging from hours (the δ Sct-type variability) to a few days (spots/rotational variability). The physical parameters of the components and the origin of the photometric variability are discussed in more detail.
Observing Planet-driven Dust Spirals with ALMA

Published: May 2022

Atacama Large Millimeter/submillimeter Array (ALMA) continuum observations of thermal emission from the dust component of protoplanetary disks have revealed an abundance of substructures that may be interpreted as evidence for embedded planets, but planet-driven spiral arms—perhaps one of the most compelling lines of evidence—have proven comparatively elusive. In this work, we test the capabilities of ALMA to detect the planet-driven spiral signal in continuum emission. Carrying out hydrodynamic simulations and radiative transfer calculations, we present synthetic Band 7 continuum images for a wide range of disk and observing conditions. We show that thermal mass planets at tens of astronomical units typically drive spirals detectable within a few hours of integration time, and the detectable planet mass may be as low as ∼Neptune mass (0.3 M
th). The grains probed by ALMA form spirals morphologically identical to the underlying gas spiral. The temperature of the dust spiral is crucial in determining its contrast, and spirals are easier to detect in disks with an adiabatic equation of state and longer cooling times. Resolving the spiral is not necessary for its detection; with the help of residual maps, the optimal beam size is a few times the spiral width at a constant noise level. Finally, we show how the presence of gaps and rings can impair our ability to recognize colocated spirals. Our work demonstrates the planet-finding potential of the current design specification of ALMA, and suggests that observing capability is not the bottleneck in searching for spirals induced by thermal mass planets.
Experiments on the Electrostatic Transport of Charged Anorthite Particles under Electron Beam Irradiation

Published: May 2022

To reveal the effect of secondary electron emission on the charging properties of a surface covered by micron-sized insulating dust particles and the migration characteristics of these particles, for the first time we used a laser Doppler method to measure the diameters and velocities of micron-sized anorthite particles under electron beam irradiation with an incident energy of 350 eV. Here, anorthite particles are being treated as a proxy for lunar regolith. We experimentally confirm that the vertical transport of anorthite particles is always dominant, although horizontal transport occurs. In our experiments, some anorthite particles were observed to have large vertical velocities up to 9.74 m s−1 at the measurement point. The upper boundary of the vertical velocities V
z of these high-speed anorthite particles are well constrained by its diameter D, that is,

V

linearly depends on D
−2. These velocity–diameter data provide strong constraints on the dust charging and transportation mechanisms. The shared charge model could not explain the observed velocity–diameter data. Both the isolated charge model and patched charge model appear to require a large dust charging potential of −350 to −78 V to reproduce the observed data. The microstructures of the dusty surface may play an important role in producing this charging potential and in understanding the pulse migration phenomenon observed in our experiment. The presented results and analysis in this paper are helpful for understanding the dust charging and electrostatic transport mechanisms in airless celestial bodies such as the Moon and asteroids in various plasma conditions.
MiMO: Mixture Model for Open Clusters in Color–Magnitude Diagrams
Authors: Li 李 Lu 璐 , Shao 邵 Zhengyi 正义
Published: May 2022

We propose a mixture model of open clusters (OCs) in color–magnitude diagrams (CMDs) to measure the OC properties, including isochrone parameters (age, distance, metallicity, and dust extinction), stellar mass function (MF), and binary parameters (binary fraction and mass-ratio distribution), with high precision and reliability. The model treats an OC in the CMD as a mixture of single and binary member stars and field stars in the same region. The cluster members are modeled using a theoretical stellar model, mass function, and binary properties. The field component is modeled nonparametrically using a separate field-star sample in the vicinity of the cluster. Unlike conventional methods that rely on stringent member selection, ours allows us to use a sample of more complete cluster members and attendant field stars. The larger star sample reduces the statistical error and diminishes the potential bias by retaining more stars that are crucial for age estimation and MF measurement. After validating the method with 1000 mock clusters, we measured the parameters of 10 real OCs using Gaia EDR3 data. The best-fit isochrones are consistent with previous measurements in general but with more precise age estimates for several OCs. The inferred MF slope is −2.7 to −1.6 for clusters younger than 2 Gyr, while older clusters appear to have significantly flatter MFs. The binary fraction is 30%–50%. The photometric and astrometric distances agree well.
Ion-scale Transition of Plasma Turbulence: Pressure–Strain Effect
Authors: Hellinger Petr , Montagud-Camps Victor , Franci Luca , Matteini Lorenzo , Papini Emanuele , Verdini Andrea , Landi Simone
Published: May 2022

We investigate properties of solar-wind-like plasma turbulence using direct numerical simulations. We analyze the transition from large, magnetohydrodynamic (MHD) scales to the ion characteristic ones using two-dimensional hybrid (fluid electrons and kinetic ions) simulations. To capture and quantify turbulence properties, we apply the Karman–Howarth–Monin (KHM) equation for compressible Hall–MHD (extended by considering the plasma pressure as a tensor quantity) to the numerical results. The KHM analysis indicates that the transition from MHD to ion scales (the so-called ion break in the power spectrum) results from a combination of an onset of Hall physics and an effective dissipation owing to the pressure–strain energy-exchange channel and resistivity. We discuss the simulation results in the context of the solar wind.
Estimating the Injection Duration of 20 MeV Protons in Large Western Solar Energetic Particle Events
Authors: Li Gen , Lugaz Noé
Published: May 2022

An ad hoc analytical calculation is presented to infer the duration of injection of 20 MeV protons in 21 selected western solar energetic particle (SEP) events. We convolve the solution of diffusion equation with a “triangle” source to model the time-intensity profiles over the onset and the peaking phase. The effects of “corotating” flux tubes and of solar wind convection are neglected. To accommodate these simplifications, only western events whose associated flares erupted between W15 and W90 are selected. The time-intensity profiles of these events are reconstructed from the timescales presented in Kahler (2005) and Kahler (2013) using the modified Weibull function. From the linear relation between the logarithm of the peak intensity and the logarithm of the fluence of 27–37 MeV protons presented in Kahler & Ling, we derive an optimal radial mean free path (λ
mfp) of 0.08 au and adopt this value to fit all selected events. The inferred duration of injection for the selected events, which in general increases with the initial speed of the associated coronal mass ejection (CME) (V
cme), is less than 1 hr for V
cme < 1000 km s−1 and varies from a few to ∼10 hr for 1000 km s−1 < V
cme < 2000 km s−1. We then estimate the distance that the associated CMEs have traveled over the duration of injection. Most CMEs in selected events have traveled to less than 60 solar radii by the time the majority of accelerated particles have been injected into the interplanetary space.

We have modeled the velocity-resolved reverberation response of the Hβ broad emission line in nine Seyfert 1 galaxies from the Lick Active Galactic Nucleus (AGN) Monitoring Project 2016 sample, drawing inferences on the geometry and structure of the low-ionization broad-line region (BLR) and the mass of the central supermassive black hole. Overall, we find that the Hβ BLR is generally a thick disk viewed at low to moderate inclination angles. We combine our sample with prior studies and investigate line-profile shape dependence, such as

, on BLR structure and kinematics and search for any BLR luminosity-dependent trends. We find marginal evidence for an anticorrelation between the profile shape of the broad Hβ emission line and the Eddington ratio, when using the rms spectrum. However, we do not find any luminosity-dependent trends, and conclude that AGNs have diverse BLR structure and kinematics, consistent with the hypothesis of transient AGN/BLR conditions rather than systematic trends.
A Rapid and Large-amplitude X-Ray Dimming Event in a z ≈ 2.6 Radio-quiet Quasar
Authors: Liu Hezhen , Luo B. , Brandt W. N. , Huang Jian , Pu Xingting , Yi Weimin , Yu Li-Ming
Published: May 2022

We report a dramatic, fast X-ray dimming event in a z = 2.627 radio-quiet type 1 quasar, which has an estimated supermassive black hole (SMBH) mass of 6.3 × 109
M
⊙. In the high X-ray state, it showed a typical level of X-ray emission relative to its UV/optical emission. Then its 0.5–2 keV (rest-frame 1.8–7.3 keV) flux dropped by a factor of ≈7.6 within two rest-frame days. The dimming is associated with spectral hardening, as the 2–7 keV (rest-frame 7.3–25.4 keV) flux dropped by only 17%, and the effective power-law photon index of the X-ray spectrum changed from ≈2.3 to ≈0.9. The quasar has an infrared (IR)-to-UV spectral energy distribution and a rest-frame UV spectrum similar to those of typical quasars, and it does not show any significant long-term variability in the IR and UV/optical bands. Such an extremely fast and large-amplitude X-ray variability event has not been reported before in luminous quasars with such massive SMBHs. The X-ray dimming is best explained by a fast-moving absorber crossing the line of sight and fully covering the X-ray emitting corona. Adopting a conservatively small size of 5 GM
BH/c
2 for the X-ray corona, the transverse velocity of the absorber is estimated to be ≈0.9c. The quasar is likely accreting with a high or even super-Eddington accretion rate, and the high-velocity X-ray absorber is probably related to a powerful accretion-disk wind. Such an energetic wind may eventually evolve into a massive galactic-scale outflow, providing efficient feedback to the host galaxy.
Terniopsis yongtaiensis (Podostemaceae), a new species from South East China based on morphological and genomic data
Authors: Zhang Miao , Zhang Xiao-Hui , Ge Chang-Li , Chen Bing-Hua
Published: May 2022

The new species Terniopsis yongtaiensis X.X. Su, Miao Zhang & Bing-Hua Chen, from Fujian Province, China, is described and illustrated. It is similar to T. heterostaminata from Thailand, but differs in its two fertile stamens, fewer but longer vegetative ramuli, fewer but shorter flowering ramuli, shorter pedicels, capsule-stalk and stamens. The complete chroloplast genome of the new species is 129,074 bp long and has a typical quadripartite structure, including two inverted repeat regions (IRs) of 18,504 bp in length, separated by a large single-copy (LSC) and a small single-copy (SSC) regions of 79,000 bp and 13,066 bp, respectively. The ycf1 and ycf2 genes were lost compared to most higher plants, leading to a substantial reduction in the IR. The phylogenetic analysis using both matK and nrITS revealed that T. yongtaiensis is sister to T. heterostaminata with moderate support, and formed a clade with other Terniopsis species, suggesting that the new species belongs to Tristichoideae.
Three new species of Macrostomum (Platyhelminthes, Macrostomorpha) from China and Australia, with notes on taxonomy and phylogenetics

Published: May 2022

In this paper, three species of the macrostomid free-living flatworm genus Macrostomum are described. Two species, Macrostomum littorale Wang & Shi, sp. nov. and M. shekouense Wang & Shi, sp. nov., were collected from coastal water at Shenzhen, Guangdong Province, China. One species, M. brandi Wang & Shi, sp. nov., was collected from Perth, Western Australia and Queenscliff, Victoria, Australia. Macrostomum littoralesp. nov. differs from congeneric species within the genus in the length of the stylet, diameter of stylet opening, and the bend of the stylet. Macrostomum shekouensesp. nov. and M. brandisp. nov. differ from similar species within the genus in the stylet morphology, position of the female antrum and developing eggs, or presence or absence of the false seminal vesicle. Phylogenetic analysis based on cytochrome c oxidase subunit I (COI) gene shows that M. littoralesp. nov. and M. hystrix are sister clades on two well-separated branch, M. shekouensesp. nov. and M. brandisp. nov. are sister clades on two well-separated branches. Accordingly, both morphological and molecular evidence support M. littoralesp. nov., M. shekouensesp. nov., and M. brandisp. nov. as three new species.

Cet article propose une analyse de l’action enseignante de formateurs 1  de FLE intervenant dans le contrat d’intégration républicaine. Les sept participants ont été interviewés à deux reprises. Les premiers entretiens visaient à recueillir des récits de vie professionnelle, et à créer un espace de partage pour donner à voir des pratiques passées sous silence. Ces entretiens ont par la suite été représentés sous forme de carte mentale individuelle, présentant les actions glottopolitiques et les imaginaires de chaque participant. Cette cartographie a été présentée dans un deuxième entretien, dans une logique de co-construction du sens accordé aux expériences professionnelles. Ce travail a permis d’identifier des conflits entre identité professionnelle et personnelle, et parfois de reconstruire la diachronie personnelle d’actions enseignantes. L’article propose un bilan de cette enquête, des questionnements méthodologiques et des perspectives de recherche pour mener une immersion glottopolitique dans une démarche interventionniste co-construite, reposant sur des pactes de recherches équitables entre les participants et les chercheurs.
Pour une linguistique stratégique : points de vue militant et chercheur
Authors: Ramanitra Mahieu
Published: May 2022

Pourquoi et comment la linguistique appliquée et la stratégie militante peuvent-elles poursuivre les mêmes buts, et au-delà de l’objectif flou de « combat », quels sont ces buts, ces points communs ? Leur point commun serait-il cet objectif pragmatique du « faire », de l’action sur, avec, pour et au plus proche du réel, qu’évoquent la notion de combat comme celle « d’application » (par opposition à des approches plus objectivistes ou modélisatrices) ? Mon hypothèse de départ sera que l’intérêt de la linguistique appliquée pour le combat peut reposer sur les fondements épistémologiques et sociaux que sont les linguistiques systémique, interactionnelle, et populaire, qui contiennent déjà, par leur fort lien au réel langagier et extra-langagier, les embryons d’une linguistique stratégique. Après avoir défini les termes de « linguiste populaire », « combat », « militant » et « stratégie » et leurs problématiques, nous expliquerons comment le manque de stratégie (au profit de l’action) des militantes et militants coïncide avec leur manque de scientificité (d’un point de vue linguistique) et comment la linguistique appliquée académique elle-même manque de clés de lecture stratégiques, même (et surtout) par rapport à des linguistes populaires militants. Nous verrons ensuite comment la linguistique peut apporter à la stratégie sa précision empirique et interactionniste et comment la stratégie peut apporter à la linguistique son analyse contextuelle et politique, que ce soit pour des objets de recherche... ou pour les combats institutionnels et surtout sociaux de la discipline.
Regressive assimilation of voice in French
Authors: Akamatsu Tsutomu
Published: May 2022

En français, des séquences de deux sons consonantaux différents peuvent apparaître, parmi d’autres contextes, à travers deux mots, de façon que la première consonne se trouve à la finale du premier mot et que la deuxième se trouve au début du deuxième mot (par ex., ro b (e) f endue ), les deux mots étant prononcés sans pause entre eux. Quelques auteurs proposent une analyse phonologique des deux sons selon laquelle la deuxième consonne ([f]) est le phonème (/f/) alors que la première consonne (/b/) subit le processus [b] > [p] par assimilation régressive de voix dans la réalisation de l’archiphonème /P/ qui résulte de la neutralisation de /p/ vs /b/. Je ne suis pas d’accord avec cette interprétation phonologique. En français, la première consonne est prononcée [b̥] (comme l’indiquent depuis longtemps les phonéticiens) qui est une variante combinatoire du phonème /b/, et les deux consonnes en question sont /b/ et /f/. Il n’y a donc aucune neutralisation de /p/ vs /b/. En français, dans un pareil cas, l’assimilation régressive de voix est indépendante de l’assimilation régressive d’énergie, non comme en russe où l’assimilation régressive de voix et l’assimilation régressive d’énergie sont concomitantes. Lorsque, en français, les deux consonnes différentes apparaissent comme dans ro b (e) f endue à la jonction de deux mots, il n’y a pas neutralisation là où on trouve [b̥] ( b de ro b e ). Ce qui n’est pas le cas lorsqu’une succession de deux consonnes différentes apparaît à l’intérieur d’un mot, comme dans mé d ecin [me t sɛ̃] et ane c dote [ane g dɔt] . Dans ces cas, il y a neutralisation là où [t] et [g] apparaissent. Les analyses phonologiques doivent être en accord avec, et se fonder sur, des observations phonétiques correctes.
Time items in Russian key cultural texts and their English translations
Authors: Khaïroulline Vladimir
Published: May 2022

L’article explique comment le paramètre du temps est traité dans les textes clés de la culture russe par Léon Tolstoï et Fiodor Dostoïevski et leurs traductions en anglais. On soutient que l’anglais préfère concrétiser des unités temporelles, c’est-à-dire utiliser des morceaux de temps plus courts ou plus concrets, tandis que le russe a tendance à généraliser, ou à employer des périodes plus longues. Le russe est apte à traiter le temps moins définitivement, de sorte que les limites temporelles peuvent sembler ambiguës. Dans des cas similaires, l’anglais divise la continuité du temps plus définitivement.

Nécessaire, la désoccidentalisation de l’aide internationale est en marche. La décentralisation des financements et la responsabilisation des acteurs locaux l’illustrent. Mais le partenariat Nord-Sud reste noyauté par des a priori . Si le pays d’origine des acteurs humanitaires est un facteur déterminant de l’asymétrie des relations entre coopérant et bénéficiaire, le sentiment de ce dernier est tout aussi décisif.

En déposant un projet de loi criminalisant le « triple talaq  », le gouvernement indien rompt avec les pratiques consultatives en matière de législation sur des matières communautaires. Visant officiellement à protéger la femme musulmane, cette initiative sert surtout l’image du Premier ministre. La démarche est sous-tendue par un imaginaire représentant la femme musulmane comme victime passive et l’homme musulman comme lubrique et barbare.

Le virage à droite du féminisme, opéré ces dernières années en Occident par des femmes d’influence, s’est nourri des convergences entre thèmes féministes, injonctions néolibérales et discours anti-émancipateurs. De cet enchevêtrement s’inspirent tant un « féminisme néolibéral » qu’un « féminisme suprémaciste occidental ». Les débats que ces courants capitalistes et xénophobes suscitent tendent à revigorer en retour les féminismes progressistes.
L’urgence écologique vue du Sud

Sortir par le haut des cinq dilemmes de la crise environnementale implique de la considérer d’urgence comme un enjeu central ; de prendre acte du fait que les populations les plus vulnérables ne sont pas nécessairement celles qui lui donnent priorité ; de faire valoir la dette écologique des (pays) riches à l’égard des (pays) pauvres ; de rejeter le business as usual , même « verdi » ; et d’opter résolument pour un changement de paradigme, sans snober les conditions sociales et politiques d’une transition régulée.

The demands of different regions can be predicted and supplies may be dispatched by the central agencies based on certain predictions. Region-wise growth factors of Covid-19, diabetic patients, cardiovascular patients and other important factors are taken to generate a priority metric based on the correlation matrix, which is calculated from the different covariance matrix against different influencing factors including growth factor and doubling period. All the factors are normalized on a scale of 1 to 10 to adjust different quantities from all the factors. A dynamic priority queue is used to store the priority scores of each region, which is calculated from all the correlation values of correlated factors with respect to growth factor. Priority for each region is calculated and stored in the priority queue and sorted it in decreasing order, based on which, the supply of food and emergency supplies are dispatched according to the priority of different regions.

Regional logistics integration is of great significance for constructing a new pattern of domestic and international double cycle development. However, the regional logistics service capacity is unbalanced. There is a desire for researchers and policy makers to evaluate the degree of its regional logistics. Therefore, establishing reasonable indicator system for regional logistics plays an important role in the regional sustainable development. This paper uses factor analysis to establish the evaluation indicator system of regional logistics capability. Afterwards, eleven major cities in Jiangxi province China are selected for a comprehensive evaluation using the factor analysis method.The eleven cities are then ranked based on the scores and three tiers are accordingly classified. Based on these results, sustainable development policies for Jiangxi province to improve its regional logistics sustainability are proposed.

Published: May 2022

With the development of new energy vehicles, it is necessary to develope new fast charging cathode materials for lithium ion batteries. This paper reports a simple carbon thermal reduction routine to synthesize layered LiMoO2 cathode for Li-ion batteries. Impurity-free micro-crystalline powders were synthesized by one-step method with a thermal treatment at 800°C for 5 hrs under N2 atmosphere. The structural, morphological and electrochemical properties of LiMoO2 were characterized by using X-ray diffraction pattern (XRD), scanning electronic microscopy (SEM), charge/discharge cycling and electrochemical impedance spectroscopy (EIS). The diffraction results indicate that the prepared sample has a layered hexagonal structure related to α-NaFeO2. The secondary particles are in order of 2.0 μm length on average with homogeneous distribution. The initial discharge capacity of LiMoO2 is 110.9 mAh·g-1 at 0.1 C, and the capacity can still remain 92.8 mAh·g-1 after 100 cycles. The good cycling performance and high rate discharge performance are attributed to the smaller charge-transfer resistance revealed by EIS results.

In Algeria, the calcined dam's mud is a local renewable waste that proved its use as a supplementary cementitious material (SCMs) with similar mechanical performances and better resistance to several physical and chemical attacks than Portland cement. In the same context, the main objective of the work is to evaluate the effect of this calcined mud on thermal conductivity, which was never tested. To concretize this goal, one mortar based on control cement (CEMI) and three others based on modified cement by replacing CEMI by 10% to 30% Wt rates with the calcined mud of Chorfa dam have been prepared and cured before being put to the test procedure. Compressive strength, apparent density, water absorption after immersion, and thermal conductivity at three degrees of saturation state (saturated, outdoors, and dried state) were tested. The results show that using 10% to 20% replacement rate is characterized by good free lime and calcium hydroxide consumption that produces C-S-H gel, fills pores, decreases porosity, and increases density. The thermal conductivity of mortars based on the calcined mud in all states was lower compared than the control mortar, at saturated state by 16.28%, 17.83%, and 18.60% for the mortars 10%, 20%, and 30% (of cement replacement) respectively, at outdoors state by 5.5%, 4%, and 17.5% and dry state with 8.39%, 20.65%, and 38.07%. 10% to 20% mud replacement is beneficial for use in masonry and plastering wall applications of a building's envelope. 30% replacement rate can be developed and used in environments with minimal class expositions.

Published: May 2022

The search for new materials that serve as dressings and promote the proper means for wound healing, without yielding toxic waste to the wound bed and at low cost, is currently the subject of research. In this sense, the present study aimed to develop a prototype of a poly(vinyl alcohol) (PVA) polymeric film, sodium carboxymethylcellulose (NaCMC). PVA and NaCMC as miscible polymer blend films for wound dressings was developed using internal mixing chamber processing in a mix torque rheometer (MTR) without the use of binders or crosslinks in different mixing conditions that were investigated by thermal characteristics (differential scanning calorimetry (DSC)) and thermogravimetric analysis (TGA) and crystallinity (X-ray Diffraction Technique (XRD)). The films obtained by pouring from this starting material were characterized by DSC, TGA, Fourier transform infrared spectroscopy (FTIR), scanning electron microscope (SEM), optical microscopy and swelling assay. All stages of development of this prototype are discussed, from the quality control of the raw materials, through the development of the preparation technique of the blends in 14 different processing conditions. The processed PVA/NaCMC film showed physical crosslinking which may have promoted its ability to resist dissolution in water (unprocessed PVA/NaCMC films’ characteristic). The results demonstrated that the processing of the PVA and NaCMC polymers in the MTR constitutes a viable technique to obtain membranes for use as dressings.

Background

The COVID-19 pandemic and control measures may have had an impact on unpleasant emotions experimented during the lockdown (LD). This may have increased the number of hours spent online and could have impacted the quality of the enacted behavior, in terms of loss of control of Internet use. In this online survey, we were interested in measure how much loss of control was perceived regarding online gambling, online shopping, the fruition of online pornographic content and web navigation.

Design and methods

The online survey was carried out during the COVID-19 pandemic in the post-lockdown and 1232 subjects participated in the survey. In the participating sample, healthcare workers (HW) were 43.1% of the sample, of which 18.7% were directly involved in the Coronavirus emergency, and 52.3% of the sample is not a HW. Only 0.6% of the sample gambled online and 37.5% of those reported losing control of their gambling mode. Most of the sample shopped online during the LD (70.1%), but only 7.2% of those lost control by buying and/or spending more than what they had set themselves.

Results

Significant data emerged showing that those who lost control while online shopping also lost control regarding the amount of time spent online (p<0.001); 21.6% of the sample, reported making use of online pornographic material during LD, 4.7% of them stated that the frequency increased and 5.1% reported losing control by having spent more money or more time than what was intended. Finally, 44.7% of the sample have experienced loss of control during the web navigation. Furthermore, during the LD 67.8% of the sample reports having experienced unpleasant emotions. Of these, 8.4% state that they enacted behaviors such as online gambling, online shopping, online pornographic material viewing and web navigation to counter their negative emotions. Interestingly, we found a correlation between loss of control during web navigation and online shopping and the emotional states “upset”, “scared” and “restless” (p<0.05).

Conclusion

To conclude, there was no significant increase in potentially addictive behaviors, nor an increase in loss of control of these behaviors when enacted online. However, the loss of control in online shopping and web navigation was significantly correlated to the unpleasant emotional states of nervousness, fear and restlessness, whereas those who reported feeling strong and able to handle the situation experienced a lower loss of control in their web navigation. These correlations may suggest that these online behaviors may act as modulators of unpleasant emotional states.

Postoperative pain and persisting fatigue represent critical concerns for patients receiving lung transplantation. The purpose of this study was to illustrate the trajectory of symptoms in a patient who presented with a posttransplant musculoskeletal syndrome after double redo-lung transplantation and attended therapeutic sessions of global postural re-education during the symptomatic phase. A 32-year-old woman with interstitial lung disease underwent double lung transplantation. At 23 months, functional parameters deteriorated, and the patient was placed on the active list for a second double-lung transplantation. Twenty months after re-transplantation, the patient reported continuous thoracic-lumbar musculoskeletal pain exacerbated by moving or performing the standard motor activities. Lower body flexibility improved during the observation period changed from -10 cm to 0 cm at the Chair Sitand- Reach Test. Leg strength improved as well, and the patient was able to perform more repetitions at the Squat Test, improving from 14 to 39. Pain intensity changed from 7 to 4 on a numerical rating scale. We observed that outcomes strictly related to treatment, with lower body flexibility, pain intensity, and physical function improving over time. As a result global postural re-education proved to be effective in this patient.
