Published: March 2022

Состояние проблемы. Большинство современных памятников архитектуры, в частности культовых сооружений, выполнены из камня или обожженного кирпича. Конец XIX века принес в строительную индустрию новые прогрессивные конструкционные материалы. Их повсеместное применение надолго отодвинуло на второй план не только каменное строительство, но и всевозможные исследования сводчатых и арочных элементов из кирпича. Множество различных факторов приводят к образованию повреждений, в частности трещин, воздействие которых на несущие конструкции до сей поры изучено недостаточно. Результаты. Для изучения влияния указанных повреждений на несущую способность проведены и проанализированы численные и физические исследования. В качестве объекта для изучения выбран храм в честь Рождества Пресвятой Богородицы в с. Кабаличи Брянской области. Осуществлено инструментальное освидетельствование памятника, выполнена и испытана лабораторная модель подлинного сооружения. Выводы. Достаточно серьезным повреждением, способным привести к трещинообразованию в несущих конструкциях сводов, является смещение опор. Однако образование трещин происходит при довольно больших смещениях и не всегда приводит к исчерпанию несущей способности свода.
Statement of the problem. Most of the modern architectural monuments, in particular religious buildings, are made of stone or baked bricks. The end of the 19 century brought new progressive materials to the construction industry. Their widespread use for a long time pushed into the background not only stone construction but also all kinds of studies of vaulted and arched brick elements. A lot of influencing factors led to the damage, in particular the formation of cracks, the effect of which on the supporting structures has not been sufficiently studied so far. Results. To study the effect of these damages on the bearing capacity, we carried out and analyzed numerical and physical experiments. We took as an analogue for the study «The Temple in Honor of the Nativity of the Blessed Virgin Mary (Rozhdestva Presvyatoy Bogoroditsy)» in the village of Kabalichi, Bryansk region, Russia. We carried out an instrumental inspection of the monument, built and tested a laboratory model of the original structure. Conclusions. A sufficiently serious damage that can lead to cracking in the bearing structures of the vaults is the displacement of the supports. However, cracking occurs at rather large displacements and does not always lead to the exhaustion of the load-bearing capacity of the roof.

Stunting is a chronic nutritional problem in toddlers with shorter height than from the age of the child. Stunting is caused by many factors such as maternal health conditions, maternal nutrition, history of disease in the mother, nutritional intake in newborns and toddlers, social and economic conditions, clean water sanitation, disease infections. The impact of stunting on toddlers can lead to increased morbidity and mortality in children, impaired child development and growth, increased health costs, decreased productivity, increased risk of disease, reproductive health problems, to non-optimal working capacity in the future. The purpose of community service is to provide health education about stunting, the causes of stunting, the impact of stunting and the impact of stunting. The method of activity is health education (Promoting) in 45 participants of kesehatan cadres and PKK members. The results of health education activities that amounted to 75.6% knowledge about stunting is good, and 24.6% knowledge about stunting is sufficient.
Pengaruh Variasi Waktu Fiksasi Sediaan Apus Darah Tepi (SADT) pada Pengecatan Giemsa terhadap Morfologi Sel Darah Merah

Published: March 2022

The Blood Smear is a slide whose one of the surfaces is coated using a thin layer of blood and stained with painting of giemsa or wright. Before painting, the preparation is fixated with methanol (methyl alcohol). Prolonged fixation should be avoided because methanol affects subsequent painting and causes some inhibition of intracellular enzymes. Methanol that is left too long in the open air will evaporate (decrease in concentration) and contain water so that it will affect erythrocyte morphology. This study aims to find out the effect of variations in sadt fixation time on giemsa painting on the morphology of red blood cells. This type of research is an experiment. The sample numbered 30 in the form of peripheral blood smear preparations divided by 3 based on variations in fixation time of 3 minutes, 5 minutes and 10 minutes. The results of the Chi-Square statistical test obtained a signification value of 0.00 < 0.05 means that there is a significant difference in time variation in the morphological quality of cells. And the fixation time is best with a fixation time of 3 minutes, at a fixation of 5 minutes still found some crenation cells (cell grinding) with moderate criteria (<3) while fixation with a time of 10 minutes is found a lot of crenation cells (>3).

Abstract
The Extremely Large Telescope and the Thirty Meter Telescope will use state of the art multiconjugate adaptive optics (MCAO) systems to obtain the full D
4 advantage that their apertures can provide. However, to reach the full astrometric potential of these facilities for on-sky science requires understanding any residual astrometric distortions from these systems and find ways to measure and eliminate them. In this work, we use Gemini multiconjugate adaptive optic system (GeMS) observations of the core of NGC 6723 to better understand the on-sky astrometric performance of MCAO. We develop new methods to measure the astrometric distortion fields of the observing system, which probe the distortion at the highest possible spatial resolution. We also describe methods for examining the time-variable and static components of the astrometric distortion. When applied to the GeMS Gemini South Adaptive Optics Imager (GSAOI) data, we are able to see the effect of the field rotator at the subpixel level, and we are able to empirically derive the distortion due to the optical design of GeMS/GSAOI. We argue that the resulting distortion maps are a valuable tool to measure and monitor the on-sky astrometric performance of future instrumentation. Our overall astrometry pipeline produces high-quality proper motions with an uncertainty floor of ∼45 μas yr−1. We measure the proper motion dispersion profile of NGC 6723 from a radius of ∼10″ out to ∼1′ based on ∼12,000 stars. We also produce a high-quality optical–near infrared color–magnitude diagram, which clearly shows the extreme horizontal branch and main-sequence knee of this cluster.

Abstract
The photoelectron boundary (PEB) at Mars is defined to be the boundary separating the photoelectron-dominated ionosphere from the external plasma environment. Extensive studies have been presented to analyze the PEB variation in the Martian dayside ionosphere. However, the PEB was identified manually in previous studies because of the difficulty in detecting the faint photoelectron features at high altitudes. In this study, we develop an algorithm to detect these faint features and identify the location of PEB from energetic electron measurements automatically. We apply the algorithm to the measurements by the Solar Wind Electron Analyzer instrument on board the Mars Atmosphere and Volatile Evolution mission and identify a total number of 15,681 PEB crossing events accumulated from 2015 January to 2019 October, of which 9169 PEB are on the dayside and 6912 are on the nightside. Our analysis indicates that the altitude of the identified PEB tends to increase with solar extreme ultraviolet radiation and crustal magnetic field strength, in agreement with previous findings. By contrast, the PEB altitude on the nightside tends to increase dramatically with solar zenith angle but is found to be weakly influenced by the crustal magnetic field strength.

Abstract
We present ALMA high-angular-resolution (∼50 au) observations of the Class I binary system SVS13-A. We report images of SVS13-A in numerous interstellar complex organic molecules: CH3OH, 13CH3OH, CH3CHO, CH3OCH3, and NH2CHO. Two hot corinos at different velocities are imaged in VLA4A (V
sys = +7.7 km s−1) and VLA4B (V
sys = +8.5 km s−1). From a non-LTE analysis of methanol lines, we derive a gas density of 3 × 108 cm−3 and gas temperatures of 140 and 170 K for VLA4A and VLA4B, respectively. For the other species, the column densities are derived from an LTE analysis. Formamide, which is the only N-bearing species detected in our observations, is more prominent around VLA4A, while dimethyl ether, methanol, and acetaldehyde are associated with both VLA4A and VLA4B. We derive in the two hot corinos abundance ratios of ∼1 for CH3OH, 13CH3OH, and CH3OCH3; ∼2 for CH3CHO; and ∼4 for NH2CHO. The present data set supports chemical segregation between the different species inside the binary system. The emerging picture is that of an onion-like structure of the two SVS13-A hot corinos, caused by the different binding energies of the species, also supported by ad hoc quantum chemistry calculations. In addition, the comparison between molecular and dust maps suggests that the interstellar complex organic molecules emission originates from slow shocks produced by accretion streamers impacting the VLA4A and VLA4B disks and enriching the gas-phase component.

Un sentiment en action
Authors: Luca Fruci Gian 
Published: March 2022

La notion de fraternité en 1848 dans la péninsule italienne est non seulement énigmatique, ambiguë, fluide, fuyante et polymorphe, mais elle se caractérise particulièrement par sa valeur opérative en se plaçant comme un vecteur (émotionnel) de rassemblement et un facteur (pré) politique de mobilisation. Avant d’être un principe politique ou une vertu civique, la fraternité du long 1848 italien se présente comme un sentiment en action qui domine aussi bien les élans et rituels pacifiques d’identification nationale patriotique que leur déclinaison – envisagée ou réelle – guerrière. Un sentiment en action typique de la « nouvelle politique » mais que l’on peut rapporter aussi bien à l’imaginaire médiéval (isant) et catholique qu’à l’expérience de la Révolution française et du triennio républicain italien 1796-1799. Ce sentiment représente donc efficacement les caractères ascriptifs et généalogique-parentaux du canon national patriotique du Risorgimento et, d’une manière plus générale, du discours nationaliste du long XIXe siècle européen.
« Più amico che fratello »
Authors: Riall Lucy 
Published: March 2022

Au cours du Risorgimento, la famille a représenté une base importante pour l’appartenance politique à la gauche ou à la droite, tout à la fois en termes pratiques et symboliques. Elle était une source de soutien matériel et de réconfort émotionnel, et une image forte d’appartenance politique et/ ou religieuse. À cet égard, les frontières entre public et privé devinrent alors (ou demeurèrent) floues. À travers la vie de Roberto, Prospero et Massimo d’Azeglio, l’article étudie le modèle de la fraternité en tant que forme de politique démocratique. L’étude de la relation entre les trois frères témoigne qu’il est important de considérer les symboles génériques de l’appartenance nationale, comme la famille et le lien fraternel, avec leur impact et leur réception individuels. Elle témoigne, en outre, de l’existence d’un espace privé restreint qui a pu constituer un refuge intime contre la rudesse de la vie publique, mais qui suggère aussi que cette sphère domestique n’était pas exclusivement du domaine des femmes. L’amitié durable entre Prospero et Massimo montre l’importance d’étudier la vie privée des personnages publics : les aspects qui ont été tenus cachés au grand public sont, pour les historiens, souvent plus éclairants que les éléments de leur vie privée utilisés pour atteindre leurs objectifs politiques.
Des frères aux fils, des sœurs au mères
Authors: Bertilotti Teresa 
Published: March 2022

En s’appuyant sur une multitude de sources (lettres, affiches, opuscules, monuments, plaques commémoratives etc.) l’article examine le large recours au terme de fraternité fait durant la période de mobilisation et du conflit, semblant mettre au second plan des hiérarchies, celle militaire par exemple. Il analyse ensuite sa transformation avec le passage des « frères » aux « fils » et la redéfinition du rôle des autres figures parentales, dès 1918, pour enfin s’arrêter sur les commémorations et la construction de la mémoire. La solidarité née de l’expérience des tranchées se transforme alors en camaraderie tandis qu’aux femmes, exclues, ne reste que le rôle de veuves ou mères de victimes.
Tra lealtà alla Corona e fedeltà a Roma : I cardinali degli Stati sabaudi dalla Restaurazione alla fine del XIX secolo
Authors: Cozzo Paolo , Merlotti Andrea 
Published: March 2022

Nel corso del XIX secolo il regno di Sardegna visse una evoluzione territoriale : dapprima (1815) con l’acquisizione della Liguria, poi, con la cessione di Nizza e della Savoia alla Francia (1860). Nella composizione del Sacro Collegio tali mutamenti non furono privi di significato. A rappresentare la monarchia sabauda nel collegio cardinalizio a metà Ottocento (periodo segnato da tensioni fra la Santa Sede e il governo subalpino) si vennero a trovare diverse porpore (in particolare quelle dei cardinali liguri) che con casa Savoia avevano vincoli di fedeltà esili e recenti, mentre i cardinali piemontesi, specialmente quelli di estrazione nobiliare, dovettero cercare un equilibrio fra la lealtà ad un papato assediato dal neonato regno d’Italia, ed una dinastia che, per cingere la corona di quel regno, non aveva esitato a porre fine al potere temporale della Chiesa.
Quand les cardinaux font de la politique : les relations entre les cardinaux américains et Washington pendant les présidences de Ronald Reagan et George H. W. Bush (1981-1993)
Authors: Gayte Marie 
Published: March 2022

De par les spécificités de l’Église catholique aux États-Unis, les cardinaux américains occupent depuis toujours une place singulière sur la scène politique de leur pays, faisant office d’interlocuteurs entre Rome et Washington. De patriotes ardents, ils deviennent dans les années 1970, à l’instar de la hiérarchie dont ils font partie, beaucoup plus critiques à l’égard de leur gouvernement. Cet article a pour but d’étudier le rôle joué par les cardinaux américains dans les stratégies déployées par les présidents Reagan et Bush père dans les années 1980 pour neutraliser cette opposition, tout en cherchant à définir la nature du pouvoir que ces cardinaux peuvent exercer dans l’arène politique.
Gasparri, Merry del Val et le gouvernement de Pie XI
Authors: Levant Marie 
Published: March 2022

Rivalités internes et groupes de pression ont toujours traversé la Curie romaine. Dans la première partie du pontificat de Pie XI, une quasi guerre des clans s’incarne dans la rivalité entre deux figures clés : les cardinaux Gasparri, secrétaire d’État, et Merry del Val, secrétaire du Saint-Office. L’antagonisme, nourri par des origines et des personnalités éloignées, repose sur des réseaux curiaux différents, que l’on peut ramener à celui de l’intégrisme et celui du consalvisme. Un conflit aiguisé se dessine donc, qui put fragiliser un temps l’autorité du nouveau pontife. Trois périodes apparaissent : celle du Pie XI débutant, peinant à manœuvrer entre des vents contraires ; celle de l’épreuve de force et de sa résolution, sur un mode autoritaire et institutionnel ; tandis que la fin des années vingt correspond à une forme d’équilibre à la fois doctrinal, politique, et personnel.
Les diplômes du dīwān sicilien et le passé byzantin de la Sicile
Authors: Nef Annliese 
Published: March 2022

Cet article envisage la question de l’éventuel héritage byzantin au sein de la Sicile des XIe-XIIe siècle, non pas d’un point de vue génétique, tant les discontinuités et les réinterprétations constantes d’éléments qui pourraient sembler voisins abondent en Sicile entre le IXe et le XIe siècle, mais d’un point de vue «structurel» . Un point commun des époques byzantine, islamique et normande est le rôle de l’impôt et donc la conception de l’État, toutes choses étant égales par ailleurs. De ce point de vue, un certain nombre d’évolutions affectant notamment le monde rural sicilien peuvent être mieux comprises en observant non seulement ce que nous savons des pays du dār al-Islām, dont la Sicile sort avec la conquête normande, mais aussi ce que nous savons de Byzance. On relira à la lumière de ce comparatisme ce que nous disent les jarā’id-platee et les dafātir al-ḥudūd siciliens de l’organisation des campagnes insulaires.
Mercato della terra e commercio mediterraneo nel versante tirrenico tra X e XI secolo
Authors: Feniello Amedeo 
Published: March 2022

A partire dai primi decenni del 900 nel commercio della terra scompaiono i tradizionali strumenti di pagamento, in argento o in solidi di Bisanzio, sostituiti dalla moneta d’oro di provenienza musulmana e siciliana, il tarì. Questa trasformazione è frutto del principale coefficiente dello sviluppo dell’economia rurale: il commercio; la fascia tirrenica si trova proiettata all’interno del flusso di scambi in «import» ed «export» che animano il Mediterraneo musulmano. Commercio alimentato lungo tutta la costa prevalentemente da operatori di origine amalfitana e che fornisce il più valido aiuto all’agricoltura locale. Insomma, la chiave della fortuna del mondo rurale tirrenico sta tutta nell’inserimento delle città meridionali in uno spazio economico mediterraneo prevalentemente musulmano.

Published: March 2022

Background Our aim is to evaluate the possible persistence of lung parenchyma alterations, in patients who have recovered from Covid-19. Design and methods We enrolled a cohort of 115 patients affected by Covid-19, who performed a chest CT scan in the Emergency Department and a chest CT 18 months after hospital discharge. We performed a comparison between chest CT scan 18 months after discharge and spirometric data of patients enrolled. We obtained quantitative scores related to well-aerated parenchyma, interstitial lung disease and parenchymal consolidation. A radiologist recorded the characteristics indicated by the Fleischner Society and “fibrotic like” changes, expressed through a CT severity score ranging from 0 (no involvement) to 25 (maximum involvement). Results 115 patients (78 men, 37 women; mean age 60.15 years old ±12.52). On quantitative analysis, after 18 months, the volume of normal ventilated parenchyma was significantly increased (16.34 points on average ±14.54, p<0.0001). Groundglass opacities and consolidation values tend to decrease (-9.80 and -6.67 points, p<0.0001). On semiquantitative analysis, pneumonia extension, reactive lymph nodes and crazy paving reached statistical significance (p<0.0001). The severity score decreased by 2.77 points on average (SD 4.96; p<0.0001). There were not statistically significant changes on “fibrotic-like” changes correlated with level of treatment and there was not a statistically significant correlation between CT lung score and spirometric results obtained 18 months after discharge. Conclusions Patients recovered from Covid-19 seem to have an improvement of ventilated parenchyma and “fibrotic-like” alterations. The level of treatment does not appear to influence fibrotic changes.

Published: March 2022

Background The communication of the diagnosis of breast cancer induces to the patient a strong psychological trauma. Radiologists are at the forefront of communicating, either for a biopsy or the probable diagnosis of malignancy. This is a complex task, which requires the knowledge and application of correct “communicative models”, among which the SPIKES protocol represents a fundamental reference. Design and methods 110 patients, with a history of breast cancer, filled out a questionnaire consisting of six questions: five aimed at defining communication compliance with the SPIKES protocol, the sixth, consisting of six feelings, aimed at the knowledge of the next emotional state. Results Regarding compliance with various “strategic points” of the SPIKES protocol, questionnaires show that 70% of patients reported no omissions, while the remaining 30% reported omissions relatively to perception (56%), emotions (23%), setting (13%), knowledge (6%) and invitation (2%). The results showed the existence of a correlation between the final emotional state and the correct application of the SPIKES protocol; in fact, patients who reacted with a positive final emotional state-reported greater adherence to the strategic points of the SPIKES protocol. Conclusions In healthcare, knowing the communicative compliance of a team in giving “bad news” is fundamental, especially in breast cancer. The SPIKES protocol is recognized by the Literature as a fundamental reference able to affect “positively” the emotional state of patients. The proposed questionnaire is a valid tool to identify the weak points of communication and related criticalities, to improve clinical practice.
