AIM. To determine the need for early orthodontic treatment of children with bad habits, to assess the need for complex treatment and involvement of doctors of diﬀerent proﬁles to eliminate the pathology of the maxillofacial region.MATERIALS AND METHODS. A comprehensive examination of children with bad habits at the age of 1 to 3 years was carried out, which included: questioning of parents, study of dental status, distribution of children into groups depending on the degree of need for orthodontic treatment.RESULTS. The ﬁrst group included 14 children (22.58 % ± 1.26) who had bad habits but did not need specialized orthodontic treatment. The second group included 23 patients (37.09 % ± 1.01) who required orthodontic treatment by myogymnastics. Patients of the third group, which included 8 patients (12.9 % ± 1.4), required specialized orthodontic treatment with prescription of removable appliances of mechanical and (or) functional action. The fourth group consisted of 10 children (16.12 % ± 1.35) who required complex dental treatment. The ﬁfth group of need for orthodontic treatment included 7 children (11.29 % ± 1.43) who required not only dental treatment but also the involvement of general medical specialists.CONCLUSION. Among young children the prevalence of bad habits remains high and the variety of their clinical manifestations does not always provide only orthodontic treatment.

The dental system formation depends on many factors, the inﬂuence of which is signiﬁcant at all stages of development. Most often, these factors have a complex eﬀect, it can be: genetic predisposition, environmental factors, bad habits and speciﬁc causes. Timely and eﬀective orthodontic treatment of developmental abnormalities of the dentofacial apparatus remains a pressing problem for both adults and children, since dentofacial anomalies are quite common in our time and have a pronounced tendency to progress.Among the clinical manifestations associated with occlusion pathology, reverse incisal overlap is not as widespread, but is the cause of the formation of functional and morphological disorders in the maxillofacial region and other body systems.Early diagnosis and correct treatment of this pathology contributes to the harmonious development of the oral cavity and also the entire human musculoskeletal system.

Published: June 2024

AIM. To increase the eﬀectiveness of prevention of development of pulp pathology in endo-periodontal lesions in patients with chronic periodontitis.MATERIAL AND METHODS. In the course of the study, instrumental treatment of the outer surface of the extruded teeth was performed, which were divided into 3 groups: group 1 – ultrasonic skeleton “DTE D72” (n = 8); group 2 – Gracey curettes (n = 8); group 3 (control) – no treatment of the root surface (n = 8). Histological analysis of the extradited teeth, scanning electron microscopy of the teeth root surfaces treated, as well as energy dispersion X-ray spectroscopy of the examined nano-preparations were conducted.RESULTS. In the coronal pulp, in 80% of cases, the presence of intrapulmonary calciﬁcates was found, mainly in areas where cement integrity was impaired. Fractures and defects of the tooth root cement are 3 times more common in group 1 of the study than in groups 2 and 3, which correlates with the data of pigment penetration depth in the areas of cement destruction. The most eﬀective obturation of the root outer surface was found in the ﬁrst study group and amounted to 85%, which is 2 and 4 times more than the indicators of groups 2 and 3, respectively.CONCLUSION. It has been shown that the best method of prevention of pulp pathology at endo-periodontal lesions is the use of Gracie curettes for carrying out hand scaling with subsequent impregnation of the treated tooth root surface with a “Dentin-sealing liquid”.

Coronavirus disease 2019 (COVID-19) is an infectious disease typically causes lung infiltration that leads to acute respiratory distress syndrome (ARDS) which result in pulmonary fibrosis in late stage. The high morbidity and mortality rates of corona propelled the scientists to develop many types of vaccines that provide immunity against desired pathogen. The study was aimed to estimate Computed tomography (CT) score severity index of COVID-19 pulmonary infection in correlation with age, sex, and the vaccination status. Current study done on 50 patients referred to radio diagnosis department of Al-bayda Medical Center from 15 September 2021 to 17 November 2021 as cases of COVID-19 pneumonia infection. Most of high CT severity score index were in males and increasing the severity with increase the age .The highest CT score severity index seen among unvaccinated patients that support the importance of vaccination in decrease severity of COVID-19 pneumonia and hence decrease the mortality rate.

Abstract
Bars drive gas inflow. As the gas flows inward, shocks and shear occur along the bar dust lanes. Such shocks and shear can affect the star formation (SF) and change the gas properties. For four barred galaxies, we present Hα velocity gradient maps that highlight bar-driven shocks and shear using data from the PHANGS-MUSE and PHANGS-ALMA surveys, which allow us to study bar kinematics in unprecedented detail. Velocity gradients are enhanced along the bar dust lanes, where shocks and shear are shown to occur in numerical simulations. Velocity gradient maps also efficiently pick up H ii regions that are expanding or moving relative to the surroundings. We put pseudo-slits on the regions where velocity gradients are enhanced and find that Hα and CO velocities jump up to ∼170 km s−1, even after removing the effects of circular motions due to the galaxy rotation. Enhanced velocity gradients either coincide with the peak of CO intensity along the bar dust lanes or are slightly offset from CO intensity peaks, depending on the objects. Using the Baldwin–Philips–Terlevich BPT diagnostic, we identify the source of ionization on each spaxel and find that SF is inhibited in the high-velocity gradient regions of the bar, and the majority of those regions are classified as a low-ionization nuclear emission-line region (LINER) or composite. This implies that SF is inhibited where bar-driven shear and shocks are strong. Our results are consistent with the results from the numerical simulations that show SF is inhibited in the bar where the shear force is strong.

⊙ B8V star with astrometric evidence for a close companion in addition to its two wide companions at 1.3 kau (a white dwarf (WD)) and 38.7 kau (an F2V astrometric binary). Here we report on a VLTI/GRAVITY observation that revealed the close companion to be a 0.58M
⊙ star at a projected separation ρ = 100.2 mas ↔ 7.4 au, confirming the system to be a quintuple. The discovered companion explains the X-ray emission of p Pup detected by eROSITA. Moreover, we also find that the isochrone age of

Abstract
We present the results of a fourth planetary defense exercise, focused this time on the small near-Earth asteroid (NEA) 2023 DZ2 and conducted during its close approach to the Earth in 2023 March. The International Asteroid Warning Network (IAWN), with support from NASA's Planetary Defense Coordination Office (PDCO), has been coordinating planetary defense observational campaigns since 2017 to test the operational readiness of the global planetary defense capabilities. The last campaign focused on the NEA Apophis, and an outcome of that exercise was the need for a short burst campaign to replicate a real-life near-Earth object impact hazard scenario. The goal of the 2023 DZ2 campaign was to characterize the small NEA as a potential impactor and exercise the planetary defense system including observations, hypothetical risk assessment and risk prediction, and hazard communication with a short notice of just 24 hr. The entire campaign lasted about 10 days. The campaign team was divided into several working groups based on the characterization method: photometry, spectroscopy, thermal IR photometry and optical polarimetry, radar, and risk assessment. Science results from the campaign show that 2023 DZ2 has a rotation period of 6.2745 ± 0.0030 minutes; visible wavelength color photometry/spectroscopy/polarimetry and near-IR spectroscopy all point to an E-type taxonomic classification with surface composition analogous to aubrite meteorites; and radar observations show that the object has a diameter of 30 ± 10 m, consistent with the high albedo (0.49) derived from polarimetric and thermal IR observations.
Discovery and Classification in Astronomy: Scientific and Philosophical Challenges and the Importance of a Comprehensive and Consistent Classification System
Authors: Dick Steven J. 
Published: June 2024

Abstract
Throughout history, the definition of “class” and the construction of astronomical classification systems has been a deep scientific and philosophical problem: scientific because facts such as physical composition ideally need to be known for proper classification but often are not, philosophical because astronomers need to understand the philosophical assumptions behind their attempts at classification, and because different philosophical ideas such as “natural kinds” often guide classification, even if unconsciously. The primary lesson of history is that the most useful classifications of celestial objects are optimally based on their physical nature. The second lesson is that because discovery is an extended process consisting of detection, interpretation, and understanding, initial classifications may be phenomenological, based on characteristics that may be useful in early “detection” stages of extended discovery. By contrast, final classifications of “the thing itself,” is achieved only after the “understanding” stage of discovery and must have a physical basis. A third lesson is that class status is best determined within a comprehensive classification system in order to determine taxon level, e.g., class, type, subtype. Such a system, encompassing all astronomical objects, illustrates the problems of class and classification, problems that may be applied to exoplanet discoveries.
Towards computable taxonomic knowledge: Leveraging nanopublications for sharing new synonyms in the Madagascan genus Helictopleurus (Coleoptera, Scarabaeinae)

Published: June 2024

Numerous taxonomic studies have focused on the dung beetle genusHelictopleurusd’Orbigny, 1915, endemic to Madagascar. However, this genus stilll needs a thorough revision. Semantic technologies, such as nanopublications, hold the potential to enhance taxonomy by transforming how data are published and analysed. This paper evaluates the effectiveness of nanopublications in establishing synonyms within the genusHelictopleurus.In this study, we identify four new synonyms withinHelictopleurus:H. rudicollis(Fairmaire, 1898) =H. hypocritaBalthasar, 1941syn. nov.;H. vadoniLebis, 1960 =H. perpunctatusBalthasar, 1963syn. nov.;H. halffteriBalthasar, 1964 =H. dorbignyiMontreuil, 2005syn. nov.;H. clouei(Harold, 1869) =H. gibbicollis(Fairmaire, 1895)syn. nov.Helictopleurusmay have a significantly larger number of synonyms than currently known, indicating potentially inaccurate estimates about its recent extinction.We also publish the newly-established synonyms as nanopublications, which are machine-readable data snippets accessible online. Additionally, we explore the utility of nanopublications in taxonomy and demonstrate their practical use with an example query for data extraction.
Celles qui (me) parlent

Published: June 2024

Qui accepte de nous parler ? À qui ne parlons-nous pas ? Revenant sur la quête de femmes engagées dans les milices chrétiennes pendant la guerre du Liban, cet article montre que l’accès aux ex-miliciennes et leurs récits est conditionné par leur position sociale actuelle, leur trajectoire à la sortie de guerre et les sentiments moraux associés à l’engagement passé. Certaines résistances à l’enquête témoignent de sentiments négatifs à son propos et les ex-miliciennes désenchantées se trouvent bien souvent hors de portée. Ces silences façonnent l’étude des désengagements miliciens, en écartant de l’enquête les devenirs biographiques de femmes aux désengagements peu heureux.

L’objectif de cette fiche est de définir dans un premier temps la notion d’institution en la distinguant notamment des notions d’établissement, mais surtout d’organisation. Nous verrons qu’il est possible d’envisager l’institution comme un triple système : culturel, symbolique et imaginaire. Dans un second temps, nous définirons et distinguerons les termes de cadre et de dispositif dans les institutions. Nous terminerons en évoquant les recherches contemporaines sur la notion de métacadre afin de rendre compte des effets des transformations des institutions sur la vie psychique des sujets.
De la pertinence de l’utilisation de comparatifs ethnoarchéologiques pour l’étude des structures architecturales antiques
Authors: Choimet Gabrielle 
Published: June 2024

Pour pallier les carences de la documentation archéologique, par nature limitée, l’usage de données issues de l’ethnographie peut permettre de donner du sens à des vestiges anciens. Courante au Proche-Orient et en Europe, cette démarche reste rare dans la vallée du Nil moyen. Cet article vise à interroger le bien-fondé du recours à l’observation ethnographique dans le cas de la fabrication des briques de terre – massivement utilisées depuis des millénaires –, en mettant en parallèle cette activité dans le Soudan d’aujourd’hui avec ce que nous savons de celle-ci au Soudan à l’époque méroïtique (iiie siècle avant J.-C. – ive siècle après J.-C.). Une enquête menée en 2018 dans deux briqueteries traditionnelles de la vallée du Nil soudanaise a permis de produire, par l’observation des pratiques des artisans, un ensemble de données ethnographiques qui éclairent d’un jour nouveau les vestiges archéologiques. Après avoir retracé l’introduction de la brique et ses utilisations dans la vallée du Nil moyen depuis l’Antiquité puis présenté la méthode de collecte des données mise en œuvre dans le cadre de cette étude, on s’intéressera à la chaîne opératoire de fabrication des briques modernes. On rappellera ensuite le principe de l’ethnoarchéologie – selon lequel le travail ethnographique vient en aide à l’interprétation de situations archéologiques – et ses faiblesses, avant d’exposer les prérequis nécessaires à l’analogie ethnoarchéologique, que sont la convergence culturelle et des conditions géographiques et socio-économiques proches entre les deux groupes considérés, tout en gardant à l’esprit que ces conditions sont aujourd’hui remises en question par les transformations rapides des modes de vie des sociétés dites traditionnelles.Enfin, la discussion portera sur les informations apportées par l’examen des briques modernes à la compréhension des conditions de production des briques anciennes. L’étude de ces dernières permet en effet de connaître les méthodes utilisées pour leur fabrication ou leur composition mais également le caractère des productions (domestique ou de masse), la saisonnalité des travaux, la réutilisation de matériaux de récupération ou la nature des groupes humains affectés à cette tâche. Elle offre en outre la possibilité d’évaluer des rendements et donc l’investissement en temps et en force de travail, la spécialisation plus ou moins accrue requise par certains savoir-faire. Elle permet enfin d’appréhender, au moins en partie, la circulation des savoirs et des artisans, l’approvisionnement et la gestion des chantiers de construction antiques.Pour conclure, cet article souhaite proposer une place à la discipline ethnoarchéologique dans l’étude des relations entre les techniques de fabrication et leur contexte de production. L’observation de pratiques actuelles ou subactuelles appliquées à l’étude des choix techniques passés a vocation à se développer, notamment au sein de l’étude des savoir-faire.
