Published: April 2023

With the beginning of the aggression of the russian federation against Ukraine in 2014, the territory of our country began to become a leader among the replaced countries of the world. The situation escalated with the beginning of the full-scale invasion of the russian federation in February 2022, and today’s Ukraine has become the country that is the most complicated in terms of explosive devices in the world. The enemy has been ignoring the requirements of international treaties and conventions regarding the prohibition of the use of certain types of mine weapons and uses the entire range of engineering ammunition available to him. One mine weapon is a major hazard from unexploded ordnance. In addition, during hostilities, one of the most difficult tasks is to provide military reconnaissance of the area for the presence of explosive objects, demining the area and passing through the changing fields of the enemy during the offensive. For the performance of these tasks, the staff structure of the engineering troops provides for appropriate units that are equipped with both equipment and hand-held reconnaissance and demining equipment. The protest and experience of the use of engineering units of the Defense Forces shows that the mentioned equipment, reconnaissance and demining are outdated, have low efficiency and do not meet the requirements for performing tasks of this type. At the same time, due to moral obsolescence and unsatisfactory state of means of exploration and mechanization, the manual method remains the main way of making passages in variable-explosive barriers. This method is extremely dangerous and contagious to the point of losing personnel.
In order to eliminate (mitigate) the mentioned problems, research is being conducted on the development of modern perspective demining complexes, both manual and remote-control. There are questions about their evaluation according to the level of technical excellence and efficiency during research.
The article offers one of the options for a partial method of comparative assessment of the level of technical perfection of samples of demining means (complexes) using methods of simulation modeling and a progressive standard. Assessment of the degree of compliance of alternatives to demining complexes is carried out by comparing them with a standard for which there is no state standard, and general requirements or quantitative indicators. Determining compliance with the requirements consists in comparing the comprehensive indicator of the evaluated alternatives of the demining complex with the comprehensive basic indicator.

Abstract
We present deep optical imaging and photometry of four objects classified as “Almost-Dark” galaxies in the Arecibo Legacy Fast Arecibo L-band Feed Array (ALFALFA) survey because of their gas-rich nature and extremely faint or missing optical emission in existing catalogs. They have H i masses of 107–109

in the g band. We also present the results of H i synthesis observations with the Westerbork Synthesis Radio Telescope. These Almost-Dark galaxies have been identified as possible tidal dwarf galaxies (TDGs) based on their proximity to one or more massive galaxies. We demonstrate that AGC 229398 and AGC 333576 likely have the low dark matter content and large effective radii representative of TDGs. They are located much farther from their progenitors than previously studied TDGs, suggesting they are older and more evolved. AGC 219369 is likely dark matter dominated, while AGC 123216 has a dark matter content that is unusually high for a TDG, but low for a normal dwarf galaxy. We consider possible mechanisms for the formation of the TDG candidates such as a traditional major merger scenario and gas ejection from a high-velocity flyby. Blind H i surveys like ALFALFA enable the detection of gas-rich, optically faint TDGs that can be overlooked in other surveys, thereby providing a more complete census of the low-mass galaxy population and an opportunity to study TDGs at a more advanced stage of their life cycle.
Les filières sucrières : un reflet des politiques publiques ?

Le sucre est un produit stratégique depuis le XVII e siècle. Napoléon a structuré la filière à partir de la culture de la betterave avec un succès qui a perduré jusqu’au début du XXI e siècle. Aujourd’hui, l’absence d’une politique publique entraîne des difficultés majeures au point de faire perdre à la France ses capacités de production.
La nécessité de faire évoluer le modèle du marché européen de l’électricité
Authors: Solier Boris 
Published: April 2023

La crise énergétique et l’envolée des prix de l’électricité en Europe ont amené un certain nombre d’observateurs et de décideurs politiques à remettre en question le modèle de marché actuel fondé sur les coûts marginaux. Parmi les nombreuses propositions de réforme formulées, deux d’entre elles ont plus particulièrement retenu l’attention : 1) plafonner à court terme les prix du gaz utilisé pour la production d’électricité (option espagnole) ; ou 2) instaurer à moyen terme un modèle de marché dual combinant un ordre de mérite fondé sur les coûts marginaux pour les énergies fossiles à coûts variables élevés et des contrats de long terme basés sur les coûts moyens pour les producteurs bas-carbone à coûts fixes élevés (option grecque). Le débat se pose avec d’autant plus de vigueur que la hausse des coûts de l’énergie constitue le principal moteur de l’inflation en Europe, laquelle atteignait plus de 10 % sur un an en octobre 2022. Une situation qui pèse sur la compétitivité de la zone euro face à ses principaux partenaires commerciaux souvent moins sévèrement affectés par la crise énergétique.
Les secteurs électriques en marche vers un régime hybride combinant marché et planification
Authors: Finon Dominique 
Published: April 2023

La résurgence de l’intervention publique dans le secteur électrique soulève la question de savoir comment adapter au mieux le market design pour relever le défi de l’investissement associé aux objectifs de sécurité de la fourniture et de décarbonation. L’évolution vers un régime de marché hybride semble inévitable, que ce soit en Europe ou aux États-Unis, dès lors que sont introduites hors marché des énergies renouvelables intermittentes et qui, du fait d’un coût marginal nul, faussent toutes les coordinations en place. Ce régime repose sur deux formes de régulation : d’une part, une planification s’articulant avec une concurrence « pour les marchés » destinée au développement de nouvelles capacités s’appuyant sur différentes techniques et, d’autre part, une concurrence « sur le marché » limitée à la réalisation du dispatching économique. La crise actuelle liée à l’augmentation des prix de l’électricité devrait accélérer cette mutation, en donnant un poids nouveau à la recherche d’un alignement des prix de vente sur les coûts de développement du système.
Être propriétaire au seuil de la retraite : une analyse des inégalités entre générations (1910-1954)

Published: April 2023

Le patrimoine immobilier constitue une ressource essentielle au seuil de la retraite, au moment où les ménages abordent cette nouvelle étape du cycle de vie et peuvent envisager de nouveaux projets résidentiels ou une désépargne, en vendant un bien immobilier. Mais ces ressources immobilières sont détenues de façon très inégale selon les catégories sociales et les générations. L’objectif de cet article est de rendre compte des disparités du patrimoine immobilier des ménages vers l’âge de 60 ans, en s’intéressant à la possession de la résidence principale ainsi qu’à celle d’autres logements (résidence secondaire ou logement de rapport). À partir des enquêtes Logement de 1973 à 2013, nous dressons un panorama de ces inégalités au sein des générations nées entre 1910 et 1954, ainsi qu’entre elles, en resituant leurs parcours dans le contexte socio-économique dans lequel ils se sont déroulés, favorisant ou non l’achat de logements. Nous montrons que la diffusion de la propriété du logement au cours des cinquante dernières années ne s’est pas faite de manière uniforme selon les générations et les catégories sociales, les inégalités se cristallisant au seuil de la retraite. Les contextes économiques et les politiques du logement ont ainsi largement favorisé la constitution d’un patrimoine immobilier pour les générations 1935-1950, mais les inégalités se sont dans le même temps renforcées et amplifiées entre classes sociales en raison de la complexification des trajectoires familiales.

Abstract
Although CD4+CD25+FOXP3+ regulatory T (TREG) cells have been studied in patients with COVID-19, changes in the TREG cell population have not been longitudinally examined during the course of COVID-19. In this study, we longitudinally investigated the quantitative and qualitative changes in the TREG cell population in patients with COVID-19. We found that the frequencies of total TREG cells and CD45RA−FOXP3hi activated TREG cells were significantly increased 15–28 d postsymptom onset in severe patients, but not in mild patients. TREG cells from severe patients exhibited not only increased proliferation but also enhanced apoptosis, suggesting functional derangement of the TREG cell population during severe COVID-19. The suppressive functions of the TREG cell population did not differ between patients with severe versus mild COVID-19. The frequency of TREG cells inversely correlated with SARS-CoV-2–specific cytokine production by CD4+ T cells and their polyfunctionality in patients with mild disease, suggesting that TREG cells are major regulators of virus-specific CD4+ T cell responses during mild COVID-19. However, such correlations were not observed in patients with severe disease. Thus, in this study, we describe distinctive changes in the TREG cell population in patients with severe and mild COVID-19. Our study provides a deep understanding of host immune responses upon SARS-CoV-2 infection in regard to TREG cells.
Identification and Characterization of Alveolar and Recruited Lung Macrophages during Acute Lung Inflammation

Published: April 2023

Abstract
To precisely identify mouse resident alveolar macrophages (AMs) and bone marrow (BM)–derived macrophages, we developed a technique to separately label AMs and BM-derived macrophages with a fluorescent lipophilic dye followed by FACS. We showed that this technique overcomes issues in cell identification related to dynamic shifts in cell surface markers that occurs during lung inflammation. We then used this approach to track macrophage subsets at different time points after intratracheal (i.t.) instillation of Escherichia coli LPS. By isolating BM-derived macrophages and AMs, we demonstrated that BM-derived macrophages were enriched in expression of genes in signal transduction and immune system activation pathways whereas resident AMs were enriched in cellular processes, such as lysosome/phagosome pathways, efferocytosis, and metabolic pathways related to fatty acids and peroxisomes. Taken together, these data indicate that more accurate identification of macrophage origin can result in improved understanding of differential phenotypes and functions between AMs and BM-derived macrophages in the lungs.

Abstract
Tuberculosis caused by Mycobacterium tuberculosis is a leading cause of death globally and a major health concern. In humans, macrophages are the first line invaded by M. tuberculosis. Upon infection, macrophages upregulate cyclooxygenase-2 (COX-2) expression and consequently elevate the formation of PGs, including PGE2 and PGD2. Although the role of proinflammatory PGE2 in M. tuberculosis infection has been reported, the roles of PGJ2 and 15-deoxy-PGJ2 (collectively named J2-PGs), the metabolites of PGD2 with anti-inflammatory features, remain elusive. In this study, we show that M. tuberculosis (H37Rv strain)–conditioned medium stimulates human monocyte-derived macrophages (MDMs) to elevate COX-2 expression along with robust generation of PGJ2, exceeding PGD2 formation, and to a minor extent also of 15-deoxy-PGJ2. Of interest, in M1-MDM phenotypes, PGJ2 and 15-deoxy-PGJ2 decreased M. tuberculosis (H37Rv strain)–conditioned medium–induced COX-2 expression and related PG formation by a negative feedback loop. Moreover, these J2-PGs downregulated the expression of the proinflammatory cytokines IL-6, IL-1β, and IFN-γ, but elevated the anti-inflammatory cytokine IL-10 and the M2 markers arginase-1 and CD163. These anti-inflammatory effects of J2-PGs in M1-MDM correlated with impaired activation of TGF-β–activated kinase 1/NF-κB/MAPK pathways. Finally, we found that J2-PGs regulate COX-2 expression, at least partially, via PGD2 receptor (DP1) and chemoattractant receptor homologue expressed on Th2 cells/DP2 receptors, but independent of the J2-PG receptor peroxisome proliferator-activated receptor-γ. Together, our findings reveal that M. tuberculosis induces COX-2 expression in human M1-MDMs, along with robust formation of J2-PGs that mediates anti-inflammatory effects via a negative feedback loop.

Published: April 2023

Context:
Coronavirus disease (COVID-19) has led to over 2,589,638 deaths globally as of March 2021 and speedy discovery of vaccines. Nigeria started the phase one COVID-19 vaccination in March 2021 using the Oxford AstraZeneca vaccine. Reports of severe adverse events with the Oxford AstraZeneca vaccine resulted in its suspension in some countries necessitating the need to determine its safety.

Aims:
To assess the prevalence, types and severity of the adverse events following COVID-19 vaccination in Rivers State, Nigeria.

Settings and Design:
A cross-sectional study design was adopted.

Subjects and Methods:
Simple random sampling method was used to select a total of 428 adults from recipients of the first dose of COVID-19 vaccine within 28 days of vaccination. A questionnaire adapted from World Health Organisation was interviewer-administered through phone calls; responses were recorded on Kobo Toolbox.

Statistical Analysis Used:
Descriptive analysis of variables was done and the association between adverse events and age, allergy and medical history were determined. The level of statistical significance was predetermined at aP< 0.05.

Results:
In this study, 50.5% of respondents reported post-vaccination adverse events out of which 10 (4.6%) were severe (30% of the severe cases were life-threatening, 60% were hospitalised and 10% were placed on bed rest). The most common side effects were fever (73.0%), pain at the injection site (41.2%), fatigue (33.3%), body ache (17.5%) and headache (13.8%). No significant association was observed between the incidence of severe adverse events and participants with allergies or medical history.

Conclusions:
The adverse events associated with the COVID-19 vaccine were largely mild and resolved within a few days. Further research is required to classify adverse events into categories.

O estudo trata das relações étnico-raciais na trajetória escolar de jovens quilombolas do Quilombo Chácara das Rosas, no município de Canoas no estado do Rio Grande do Sul, Brasil. Trata-se de uma pesquisa qualitativa de natureza exploratória ocorrida entre os anos 2020 e 2021. Por meio da análise de conteúdo de entrevistas compreensivas e da análise documental de políticas educacionais sobre educação étnico-racial objetivamos compreender como as relações étnico-raciais são percebidas e significadas por quatro jovens quilombolas em suas trajetórias escolares no Ensino Fundamental. Sustenta-se teoricamente no campo das epistemologias do sul, políticas educacionais e no conceito de juventudes. Identificamos que a relevância da educação para as relações étnico-raciais é compreendida pelos jovens. No entanto, possuem contato pontual com a temática na escola, o que os faz procurar conhecimentos sobre suas origens culturais por meio da oralidade, em conversas realizadas com familiares no interior do Quilombo. Os conteúdos, ações e atividades relacionadas e educação das relações étnico-raciais são escassas nas escolas e influenciam na percepção de jovens negros sobre si e seus posicionamentos nos espaços coletivos.

Published: April 2023

In the present study, we repeatedly used the surface-applied paste electrolyte cell to record the electrochemical impedance spectroscopy (EIS) spectra of four coating systems with different barrier properties exposed to different environments. The absence of a liquid electrolyte allows direct recording of the electrolyte-unaltered coating response to environmental stressors. Exposures included humidity between 23% and 95%, temperatures between 10°C and 50°C, 720 h of ISO 9227 neutral salt spray (NSS), 1 y in mild continental urban climate, and for comparison, 3 y of ISO 16773 3.5% NaCl immersion. The coatings showed significantly different temperature susceptibility of impedance revealing two temperature ranges with activation energies corresponding to ionic conductivity below 20°C and conductivity influenced by polymer chain movements above 30°C. Impedances measured for intact coatings or impedances calculated from the assumed range of dielectric constant and coating thicknesses can be used as references. The EIS outcome of the laboratory tests and the time- and temperature-resolved EIS responses under atmospheric exposure were compared with the reference impedances of the coatings. Mild continental climate exposure at temperatures &lt;35°C and immersion at 23±2°C yielded better barrier performance for the two solvent-based coating systems compared to the two waterborne systems of comparable thickness and number of layers. The NSS test that proceeds at 35°C yielded better performance of both solvent-based coatings over the waterborne coatings, regardless of the thickness. EIS quantification of barrier performance, which excludes the influence of the liquid electrolyte, has provided insight into the temperature effect on the barrier behavior of the coatings under nonaccelerated and accelerated exposures and the final coating rating.
