Authors: Strafun S.S. , Zanko I.S. 
Published: July 2021

Relevance. Shoulder prosthetics is the method of choice in the treatment of patients with traumatic injuries that significantly impair joint function and are accompanied by prolonged pain.
Objective: to investigate the main causes of injuries of the shoulder joint that led to its prosthetics.
Materials and Methods. The clinical group consisted of 162 patients who underwent shoulder prosthetics in the Department of Microsurgery and Reconstructive Surgery of the Upper Limb of the SI “Institute of Traumatology and Orthopedics of NAMS of Ukraine”. There were 44.4% male and 55.5% female patients. The average age of male patients was 62±11.4 years; the average age of female patients was 66±10.1 years. The average period of seeking specialized medical care after an acute injury was 24±10.9 days and 50.6±81.1 months in patients with post-traumatic consequences. In most cases, patients underwent unipolar prosthetics of the shoulder joint (126 patients, 78.7%); 27 patients (15.6%) underwent reversible prosthetics and 9 (5.6%) – total prosthetics, respectively.
Results. In most cases, shoulder prosthetics were performed in patients with acute (up to 3 weeks from the date of injury) and old fractures and fractures of the proximal epimetaphysis of the humerus – 35 (21.6%) and 48 (29.6%) patients, respectively. The number of patients with posttraumatic aseptic necrosis of the humeral head was 49 (30.2%) (p<0.005), which indicates a high frequency of complications after osteosynthesis etc. The number of patients with massive traumatic injuries of the tendons of the rotator cuff who needed shoulder prosthetics was 18 (11.1%) and with false joints – 12 (7.4%). Unipolar prosthesis systems predominated in the general structure of the prosthesis type (126 patients, 78.7%), since reversible and total prosthesis in Ukraine were registered not so long ago.
Conclusions. The analysis of our observations showed that the causes of shoulder prosthetics are severe injuries that occur with high-energy injuries (101 patients, 62.3%) and post-traumatic aseptic necrosis (49 patients, 30.2%). Acute and old fractures and fractures of the proximal metaepiphysis of the humerus are one of the most common injuries according to the analysis (35 patients, 21.6% and 48 patients, 29.6%), and their number and complexity continues to increase with age. Understanding the etiological factors that led to shoulder endoprosthetics makes it possible to predict long-term functional results and work to reduce the number of such patients.

Summary. In 67-72% of patients with gonarthrosis, there is an angular deviation of the tibia towards the lesion. Prolonged functioning in such conditions is accompanied by patellofemoral arthrosis, in the development of which we found patterns during unicompartmental arthroplasty of the knee joint.
Materials and Methods. This publication is based on the materials of a clinical and radiological examination of 106 patients with angular deviation of the tibia who were operated on using the method of unicompartmental arthroplasty.
Conclusions. The degree of patellofemoral osteoarthritis is directly dependent on the duration of the disease and the magnitude of the angular deviation of the tibia. The most degenerative-dystrophic changes occur in the knee facet and the central facet, which are displaced in the projection of the patellofemoral joint, where cartilage degeneration, subchondral sclerosis with foci of bone destruction, pronounced marginal bone growths, and exostoses progress.

Published: July 2021

Summary. Relevance. Diabetic joint damage is common in the clinic. The blood vessels of the masticatory muscles that affect the morphogenesis of diabetic arthropathy of the temporomandibular joint remain poorly studied in this pathology.
Objective: to study the features of remodeling of blood vessels of the masticatory muscles of the temporomandibular joint in experimental hyperglycemia by quantitative morphological methods.
Materials and Methods. The study material was 45 laboratory mature white male rats, which were divided into 3 groups. The 1st group consisted of 15 intact apparently healthy animals, the 2nd included 15 rats with one-month diabetic angiopathy, and the 3rd had 15 rats with two-month specified pathology. Diabetes mellitus was simulated by a single intraperitoneal injection of streptozotocin from Sigma at a dose of 50 mg/kg. Euthanasia of animals was performed by bloodletting under thiopental anesthesia one and two months after the start of the experiment. The blood glucose concentration was determined. Histological micropreparations were made from the temporomandibular joint and the temporal and external pterygoid muscles. Morphometric measurements of small caliber arteries (outer diameter 26-50 μm), veins and microvessels of the hemomicrocirculatory tract were performed on muscle micropreparations; relative volumes of damaged synoviocytes and chondrocytes were determined on micropreparations of joints. Quantitative indicators were processed statistically.
Results and Conclusions. It was revealed that the gleam of arteries considerably decreases, their wall thickens, and endotheliocytes are damaged in the studied muscles with the modeled pathology. Venous vessels are dilated, full-blooded with a reduced wall thickness. The most pronounced changes in these experimental conditions are the structure of microvessels, which is characterized by narrowing of arterioles, precapillary arterioles and hemocapillaries, pronounced expansion of postcapillary venules and venules. Plethora, stasis, thrombosis, irregularity of the lumen, sacculation, and varicose expansions were noted in venous microvessels. Venous fullness led to hypoxia, disorders of trophism and metabolism, dystrophy, necrobiosis of muscle fibers and stromal structures, foci of infiltration and sclerosis. It was revealed that morphological changes in the vascular bed of the masticatory muscles affect the morphogenesis of diabetic arthropathy of the temporomandibular joint.

Abstract
We report the new detection of 7Be ii in the ultraviolet spectra of V5669 Sgr during its early decline phase (+24 and +28 d). We identified three blueshifted absorption systems in our spectra. The first two, referred to as low- and high-velocity components, were noticeably identified among H i Balmer, Na i D, and Fe ii whose lower energies of transients are low (<4 eV). The third absorption component was identified among N ii, He i, and C ii lines whose lower energy levels are relatively high (9–21 eV). The absorption lines of 7Be ii at 3130.583 Å and 3132.228 Å were identified as the first and second components in our observations. No evidence suggested the existence of Li i at 6708 Å in any velocity components. The estimated number density ratio of lithium relative to hydrogen, which was finally produced by this object using the equivalent widths of 7Be and Ca ii K,

Binary-stripped Stars as Core-collapse Supernovae Progenitors
Authors: Vartanyan David , Laplace Eva , Renzo Mathieu , Götberg Ylva , Burrows Adam , de Mink Selma E. 
Published: July 2021

Abstract
Most massive stars experience binary interactions in their lifetimes that can alter both the surface and core structure of the stripped star with significant effects on their ultimate fate as core-collapse supernovae. However, core-collapse supernovae simulations to date have focused almost exclusively on the evolution of single stars. We present a systematic simulation study of single and binary-stripped stars with the same initial mass as candidates for core-collapse supernovae (11–21 M
⊙). Generally, we find that binary-stripped stars core tend to have a smaller compactness parameter, with a more prominent, deeper silicon/oxygen interface, and explode preferentially to the corresponding single stars of the same initial mass. Such a dichotomy of behavior between these two modes of evolution would have important implications for supernovae statistics, including the final neutron star masses, explosion energies, and nucleosynthetic yields. Binary-stripped remnants are also well poised to populate the possible mass gap between the heaviest neutron stars and the lightest black holes. Our work presents an improvement along two fronts, as we self-consistently account for the pre-collapse stellar evolution and the subsequent explosion outcome. Even so, our results emphasize the need for more detailed stellar evolutionary models to capture the sensitive nature of explosion outcome.
The 1991 24 hr Ultraviolet Monitoring of 21 Com with IUE
Authors: Monier Richard 
Published: July 2021

Abstract
The comparison of 10 far ultraviolet spectra of 21 Com taken over continuous 24 hr (half of the recently determined rotational period) reveals large variations shortwards of 1700 Å. In contrast, the flux variations at wavelengths larger then 2200 Å are of smaller amplitudes. The large FUV variability is probably caused by changes in the continuous opacity driven by modest horizontal gradients of the abundances of chemical elements over the surface of 21 Com.
Evidence for Multiple Pulse-shape Changes during the Third Chromatic Timing Event of PSR J1713 + 0747
Authors: Lam M. T. 
Published: July 2021

Abstract
Millisecond pulsar J1713 + 0747 recently underwent a drastic change in its pulse shape. The pulsar has undergone two previous “chromatic timing events,” frequency-dependent changes in pulse arrival times, with some evidence for low-amplitude achromatic changes in the pulse shape. Ongoing monitoring efforts of the pulsar show that the latest significant shape change has persisted for several months, longer than the recovery of the behavior in previous events. I examine profiles from the Nançay Radio Telescope presented in Astronomer’s Telegram #14642 and find evidence for multiple profile shapes after the start of the third event, hinting at the possibility of several new mode changes to consider.
Introducing a Real-time Interactive GUI Tool for Visualization of Galaxy Spectra
Authors: Leung Ho-Hin , Wild Vivienne , Carnall Adam , Papathomas Michail 
Published: July 2021

Abstract
To aid the understanding of the nonlinear relationship between galaxy properties and predicted spectral energy distributions (SED), we present a new interactive graphical user interface tool pipes_vis based on Bagpipes. It allows for real-time manipulation of a model galaxy’s star formation history, dust and other relevant properties through sliders and text boxes, with each change’s effect on the predicted SED reflected instantaneously. We hope the tool will assist in building intuition about what affects the SED of galaxies, potentially helping to speed up fitting stages such as prior construction, and aid in undergraduate and graduate teaching. pipes_vis is available online (pipes_vis is maintained and documented online at https://github.com/HinLeung622/pipes_vis, or version 0.4.1 is archived in Zenodo (Leung 2021) and also available for installation through pip install pipes_vis).

Abstract
The Dual-Frequency synthetic aperture radar (DFSAR) system manifested on the Chandrayaan-2 spacecraft represents a significant step forward in radar exploration of solid solar system objects. It combines SAR at two wavelengths (L and S bands) and multiple resolutions with several polarimetric modes in one lightweight (∼20 kg) package. The resulting data from DFSAR support the calculation of the 2 × 2 complex scattering matrix for each resolution cell, which enables lunar near-surface characterization in terms of radar polarization properties at different wavelengths and incidence angles. In this paper, we report on the calibration and preliminary performance characterization of DFSAR data based on the analysis of a sample set of crater regions on the Moon. Our calibration analysis provided a means to compare on-orbit performance with prelaunch measurements, and the results matched with the prelaunch expected values. Our initial results show that craters in both permanently shadowed regions (PSRs) and non-PSRs that are classified as circular polarization ratio–anomalous in previous S-band radar analyses appear anomalous at the L band also. We also observe that material evolution and physical properties at their interior and proximal ejecta are decoupled. For the Byrgius C crater region, we compare our analysis of dual-frequency radar data with the predicted behaviors of theoretical scattering models. If crater age estimates are available, a comparison of their radar polarization properties at multiple wavelengths similar to that of the three unnamed south polar crater regions shown in this study may provide new insights into how the rockiness of craters evolves with time.

Published: July 2021

The British Virgin Islands and the US Virgin Islands, two island groups located in the Caribbean archipelago, hold unique plant diversity and high endemism. Until recently, Solanum conocarpum was considered a rare plant species endemic to the island of St. John in the US Virgin Islands. Ongoing botanical surveys in this region are revealing new populations and refining our understanding of the distribution of these narrow endemic plant species. The objective of this paper is to assess the conservation status of S. conocarpum, including a review of its geographic range, population numbers, threats and conservation actions needed for its long-term survival.
In this paper, we present new occurrences for S. conocarpum, extending its geographic range to a new island, Tortola and new territory, the British Virgin Islands. Despite this range expansion, this species is evaluated as Endangered (EN), based on Criteria B1b(iii,v)+2b(iii,v)+C2a(i), according to the IUCN Red List Categories and Criteria. The extent of occurrence (EOO = 46 km2) and area of occupancy (AOO = 20 km2) are highly restricted. On St. John (US Virgin Islands), the historically recorded individuals at Reef Bay, Europa Ridge and Sabbat Point are now considered extirpated due to disturbance from development compounded by invasive species, as well as the impact of feral ungulates and drought stress. These threats are impacting the species across the whole island of St. John and contributing to a continuing decline of suitable habitat, despite the island being a National Park. On the island of Tortola, the species occurs on unprotected lands subject to development and habitat modification and decline by feral ungulates. Based on these threats acting separately across the two islands, two locations were defined. The estimated total number of mature individuals ranges between 150 and 250, with the largest subpopulation at Nanny Point in the US Virgin Islands, containing 108 mature individuals. Conservation action, focused on protecting this species' habitat, is urgently needed.
Du style et de la langue chez Alexander von Humboldt
Authors: Péaud Laura 
Published: July 2021

Alexander von Humboldt noircit de très nombreuses pages tout au long de sa vie et de sa carrière ; ses lettres, articles et ouvrages s’ajoutant les uns aux autres pour former sa contribution aux sciences géographiques. Le processus d’écriture ne doit pas être considéré chez lui comme purement anecdotique, car il représente au contraire un des pans principaux de son activité scientifique. Avec Ludwig Fleck, on peut qualifier l’acte d’écrire chez Humboldt comme un temps de construction d’un collectif de pensée, dans la mesure où il est action de traduction du monde pour un large public. Humboldt n’ambitionne pas seulement de nouer des liens avec le monde savant, mais de rendre intelligible le monde pour le plus grand nombre. Dans cette optique, il construit un programme d’écriture qui répond à son programme scientifique. Par l’usage de métaphores, par le recours à la description picturale ou à l’artialisation du monde, il met l’accent sur le style ; pas pour minimiser le discours scientifique, mais au contraire pour mieux le faire entendre. En ce sens, le travail humboldtien est autant une œuvre de compréhension du monde que de traduction de ses phénomènes.
Tableaux et voyages : questions d’écritures et d’identité
Authors: Lefort Isabelle 
Published: July 2021

Cet article explore les relations qu’entretiennent le Tableau de la géographie de la France de Paul Vidal de la Blache (1903) et le Dépaysement, voyages en France de Jean-Christophe Bailly (2011) autour de leur enquête sur l’identité française. Si le premier s’organise autour d’une logique de « tableau » à visée panoptique, le second explicitement arrimé au principe du voyage, n’en produit pas moins une pluralité de tableaux. En quête tous deux d’une certaine identité française, ils la (re) composent dans leurs relations aux lieux et leurs restitutions. Le statisme du « tableau » ne fait jamais l’économie du mouvement, tandis que le récit de voyages, dans ses étapes, ne fait jamais celle des arrêts sur images. Les tensions entre stabilité et circulation, entre cadrage et mise en mouvement, dessinent progressivement les caractéristiques de l’identité française pour chacun. L’analyse de leurs littérarités respectives et croisées, se concentre sur deux aspects : l’analyse des images et de registres métaphoriques d’une part, l’usage et la fonctionnalité littéraire des noms propres d’autre part. Ces manières d’écrire contribuent toutes deux à des géopoïétiques nationales.
Entre a- temps -tisme et interventionnisme, l’accompagnement à l’épreuve des temps et des temporalités
Authors: Lavigne Adeline , Hintea Dorina 
Published: July 2021

Thématique omniprésente, se nichant au cœur même de l’Être Humain, de par la finitude qui l’anime, l’homme entretient une relation singulière avec la notion de temps et de temporalité(s), au gré de ses perceptions, représentations et de sa sensibilité singulière. Cette lecture si personnelle de la toile temporelle, permettant une inscription dans le réel, se voit interférer avec d’autres réalités et acceptions temporelles, plus vastes que l’échelle seule de l’individu. La question « des » temps, « des » temporalités se dessine alors et vient convoquer des questionnements, dans la démarche d’accompagnement inhérente à l’Action Sociale. Considérés comme véritables entités à part entière, les temps, les temporalités, leur articulation, leur superposition, leur synchronisation ou leur exclusion, se révèlent sources d’éclairages et vecteurs de compréhension dans l’accompagnement des personnes accueillies en structures spécialisées.
Note à propos du « métamarxisme » de Jacques Bidet
Authors: Morilhat Claude 
Published: July 2021

Partant de la nécessité de rectifier, de dépasser les incertitudes, les insuffisances du Capital , J. Bidet a élaboré, durant les trente dernières années, une ambitieuse théorie générale de la modernité, un « métamarxisme ». Le pivot de cette tentative de « reconstruction » est constitué par la catégorie originale de « métastructure ». Cette catégorie s’appuie sur le couple marché/organisation (emprunté à Marx), toutefois elle se trouve définie, développée dans le cadre de la philosophie politique contractualiste et du paradigme langagier. Mais, à travers cette entreprise théorique de « refondation du marxisme » qui assigne au langage un rôle déterminant, s’évanouissent la portée et la signification du matérialisme marxien.
