SOME ASPECTS OF SUPPORT OF THE UNIFORMITY OF MEASUREMENTS IN THE COURSE OF ARMAMENT AND MILITARY EQUIPMENT TESTING
Authors: Borshch V. , Verveiko A. , Semiroz А. 
Published: May 2022

Normative legal acts of Ukraine have changed in the field of defense the need to use the term “metrological support” to “support of the uniformity of measurements”. However, a number of normative documents envisage the metrological support of armament and military equipment. The comparative analysis of set of measures which are stipulated by metrological support and support of the uniformity of measurements is carried out and their identity in essence is shown.
The support of the uniformity of measurements requires checking the uniformity of measurements and the reliability of control.
The substantiation and clarity of the definitions of the terms “uniformity of measurements” and “reliability of control” taking into account international and national metrological documents and practice are considered. The substantiation of the term definition "uniformity of measurement", according to the authors, is questionable. The international system of SI units is now officially approved as the basic or the only system of units in all but three countries, and when using national units, they must have unambiguous connection with the system of SI units; not all indicators of accuracy are specified, in particular, correctness and precision according to DSTU GOST ISO 5725.
The term "reliability" and its derivates are considered. The term "reliability of control" and methods of determining its indicators are regulated only in the document Mi 1317. At the same time, these methods are time- consuming and difficult to understand and use. It is noted that most countries and international organizations have changed the concept of uniformity of measurement to the concept of traceability, and the terms "uniformity of measurement" and "reliability of control" are absent in the standards of advanced countries and in international dictionaries of metrology.
Measures are proposed at the legislative level and at the level of development of normative documentation to improve the uniformity of measurements.

The combat capabilities of the recconnaissance unit depend on the effectiveness of recconnaissance during the assessment of the area of operation of the unit. The methods of video processing significantly impact the quality of the task assigned to the unit. Fast and high-quality processing of video air reconnaissance allows to carry out analysis, predict trends of changes in the defensive positions of the enemy, determine their strength and location, concentration of forces for the offensive or raid. The biggest problems are connected with real-time data transmission and solving tasks that need to be solved in order to use a large number of computing resources.
The variety of digital imaging techniques and algorithms is associated with a wide range of problems that arise during the processing and transmission of digital data.
To solve important practical tasks, including the identification of useful optical signals and images on the background of interference, integrated designs are created, in which matrix receivers of the emission are combined with electronic image processing systems. At the same time, many modern articles do not take into account a number of new factors and problems related to, for example, the sharp increase in the volume of information to be processed in real time, with peculiarities of space and time selection of high definition, etc.
The peculiarities of the choice of algorithms of digital image processing in the optical-electronic devices of UAV significantly affect the probability of detection of trace objects and combat capabilities of the UAV in general.

Politiques du dénudement dans les luttes nationalistes et féministes en Égypte (1882-1956)
Authors: Bavard Florie 
Published: May 2022

Du début du xxe siècle aux années 1950, en Égypte, le geste de se dénuder se politise. Cet article s’intéresse à la façon dont des militantes et artistes mobilisent le dénudement dans leurs répertoires d’actions et dans leurs stratégies rhétoriques à des fins nationalistes ou féministes. Cette recherche propose ainsi un panorama chrono-thématique des questions relatives à la corporalité féminine, mises au-devant de la scène par ces femmes engagées. Des années 1900 aux années 1920, l’étude se focalise sur les corps féminins dans la rue, visibles, mobilisés et révélés au nom du « bien-être de l’humanité ». Puis, pour évoquer le tournant des années 1920 et 1930, l’analyse porte sur les corps dans les sports ou à la plage, exposés et « bons » pour la nation. Enfin, la réflexion se déploie sur les « beaux » dénudements et la patrie dans les arts, la mode et les concours de beauté, du milieu des années 1930 aux années 1950.
Investir sous les cocotiers. Entrepreneuralisme immobilier et production de l’espace, le cas des Français de Las Terrenas
Authors: Chapon Laurine 
Published: May 2022

Cet article analyse les modalités de la présence française dans une bourgade dominicaine, Las Terrenas. Les Français présents témoignent d’une diversité de profils, de statuts sociaux et résidentiels. Nous nous intéressons ici aux professionnels de l’immobilier et du tourisme, très nombreux parmi les Français, pour comprendre comment ils participent de manière centrale à la production de l’espace urbain en profitant et utilisant les instruments du droit à leur profit. La présence française participe à l’urbanisation et entraîne des processus de spéculation foncière et immobilière, dans un contexte de boom de la construction et d’augmentation des prix de l’immobilier. Nous analysons les conséquences de cette présence française sur les structures spatiales de Las Terrenas et nous réfléchissons également aux discours et registres mobilisés par ces acteurs pour légitimer leurs trajectoires entrepreneuriales : le droit joue un rôle central dans la naturalisation des rapports de domination.
Faire solidarité dans les politiques alimentaires de Nantes Métropole : tensions entre dynamiques participatives et affirmation d’acteurs publics
Authors: Fort-Jacques Théo , Marchadier Côme 
Published: May 2022

Pour analyser les modalités de mise en place d’une gouvernance alimentaire métropolitaine et les manières dont les acteurs issus de la société civile y prennent part, nous proposons un focus sur les régimes d’interactions liés aux politiques de solidarité alimentaire dans un cadre particulier. Autour du Projet Alimentaire Territorial (PAT) de Nantes Métropole se déploient des scènes, des discours, des groupes de travail et des engagements de politique publique qui portent spécifiquement sur les solidarités alimentaires dans la transition écologique métropolitaine. L’ambition affichée vise à élaborer, par la participation d’une pluralité d’acteurs, une politique publique dont l’enjeu est de donner à chacun un accès à une alimentation « durable » ou écologique. L’observation des ateliers dédiés à la lutte contre la précarité alimentaire conduit à un constat paradoxal. Si le processus participatif joue un rôle de mise en réseau et de mise en visibilité d’une variété d’initiatives, il peine à déboucher sur des actions concrètes susceptibles de répondre aux enjeux de vulnérabilité. En revanche, l’ambition affichée par le PAT semble s’actualiser à travers les canaux classiques de l’action publique locale et en interaction avec le tissu associatif existant, dont les projets peuvent parfois se situer en contradiction de l’action métropolitaine.
Vers un renouvellement du dialogue entre agriculteurs et régions urbaines autour de l’accès au foncier agricole. Cas de la Métropole de Montpellier, France
Authors: Hasnaoui Amri Nabil , Michel Laura , Soulard Christophe-Toussaint 
Published: May 2022

La participation des agriculteurs à l’action publique d’une métropole en matière d’alimentation locale est une question nouvelle. Elle met en relation une diversité d’acteurs agricoles et des acteurs urbains porteurs de nouvelles attentes environnementales et alimentaires qui doivent élaborer des solutions négociées. En s’appuyant sur l’analyse comparée de trois initiatives d’allocation de foncier agricole et naturel en périurbain de Montpellier, l’article met en évidence des formes variées de participation agricole à une politique agri-alimentaire territoriale. Une géographie de la participation agricole à l’alimentation urbaine est ébauchée : elle met en évidence le rôle de l’espace vécu des agriculteurs dans leurs façons de participer à une action publique locale. Elle souligne aussi le poids des modes d’action propres aux collectivités locales, notamment dans le champ de l’action d’aménagement.
L’autonomie alimentaire de Porto-Vecchio (Sud-Corse), entre initiatives locales et engagement politique
Authors: Tafani Caroline 
Published: May 2022

À Porto-Vecchio (Sud-Corse), comme dans toute l’île, la population ne peut plus se nourrir sur la seule base du système agri-alimentaire local. Premièrement, 90 % des aliments consommés proviennent de l’extérieur du territoire. Ensuite, les produits locaux sont vendus à bon prix (voire à un prix très élevé) aux 3,5 millions de touristes qui visitent l’île. Par conséquent, la population locale souffre d’une d’injustice alimentaire. Cette situation nous amène à nous interroger sur les moyens mis en œuvre par les acteurs locaux pour aborder le concept d’autonomie alimentaire du territoire – question d’autant plus pertinente dans le contexte actuel de la crise du COVID-19 et du récent changement politique dans la municipalité de Porto-Vecchio. En effet, alors que semble s’installer un mouvement durable de territorialisation de l’alimentation se pose la question suivante : entre les initiatives locales et l’engagement politique de la nouvelle collectivité, l’autonomie alimentaire peut-elle être un concept pertinent pour penser le développement durable comme une nouvelle voie de développement pour cette communauté locale ?
Decursinol angelate attenuates lipopolysaccharide induced acute lung injury by regulating AKT/NF κB pathway
Authors: Xiao Qiaosu , Li Ting , He Wenyang 
Published: May 2022

Purpose: To investigate the effect of decursinol angelate in acute lung injury induced by lipopolysaccharide treatment.
Methods: Human bronchial epithelial cells (BEAS-2B cells) and human pulmonary artery endothelial cells (HPAECs) were exposed to lipopolysaccharide to induce cell injury and then treated with 20, 40, or 60 μM decursinol angelate. Cell viability was quantified using a cell counting assay, while cell apoptosis was evaluated by western blot and flow cytometry. Colorimetric and enzyme-linked immunosorbent assay (ELISA) was used to measure oxidative stress. Expressions of tumor necrosis factor-alpha (TNF-α), interleukin-1β, and interleukin-6 were evaluated using quantitative real-time-polymerase chain reaction (qRT-PCR) and enzyme-linked immunosorbent assay (ELISA). Phosphorylation levels of p65, IκBα, AKT, and phosphatidylinositol 3-kinase were assessed by western blot, while the entry of p65 into the nucleus was investigated by indirect immunofluorescence assay.
Results: Treatment with 40 or 60 μM decursinol angelate increased cell viability after lipopolysaccharide-induced damage. B-cell lymphoma 2 (Bcl2) and Bax expression were regulated, and the rate of apoptosis was inhibited. The concentration of superoxide dismutase and glutathione was elevated, and the density of malondialdehyde and myeloperoxidase decreased significantly. Inflammation was also suppressed by decursinol angelate by regulating TNF-α, interleukin-1β, and interleukin-6 expressions. Furthermore, decursinol angelate significantly decreased the phosphorylation of p65, IκBα, AKT, and phosphatidylinositol 3-kinase. Finally, decursinol angelate inhibited p65 entry into the cell nucleus.
Conclusion: Decursinol angelate alleviates cell damage and apoptosis, reduces oxidative stress, and attenuates inflammation after lipopolysaccharide-induced acute lung injury by inhibiting AKT/NF-κB signaling pathway. Thus, decursinol angelate is a potential candidate for the treatment of lung injury.

Authors: Sulistyani Nanik , Mahfudh Nurkhasanah , Mawardi Rizky H , Zakaria Zainul A 
Published: May 2022

Purpose: To determine the effect of the ethanol leaf extract of M. calabura (EEMC) on cell leakage and time-kill against S. aureus.
Methods: The leaves were macerated with 96 % ethanol (1:8; w/v) for 27 h to produce EEMC. Chemical compounds of EEMC were analyzed using liquid chromatography with tandem mass spectrometry (LC-MS/MS). Various concentrations of EEMC (12.5; 25; 50; 100 mg/mL) were tested to determine the Minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) against S. aureus. Furthermore, EEMC was tested for its effect on cell leakage, changes in extracellular electrical conductivity, and time-kill against S. aureus. UV-spectrophotometer was used to test for leakages of nucleic acid, protein, DNA, and RNA, while atomic absorption spectrophotometer was used to evaluate leakage of potassium ion (K+).
Results: The MIC and MBC of EEMC against S. aureus were 10 % w/v (100 mg/mL). The highest cell leakage occurred in S. aureus exposed to 2x MIC, with leakages of protein, DNA, RNA, and K+ reaching 137.79 ± 58.99, 2298 ± 263.26, 1839 ± 210.61 and 770.86 ± 40.11 μg/mL respectively. The EEMC (1x MBC and 1.5x MBC) killed S. aureus in 24 h. Analysis of LC-MS/MS of EEMC showed that flavonoids (48.33 %) followed by anthraquinones (16.10 %) were the major classes of compounds present in the extract.
Conclusion: The ethanol leaf extract of M. calabura kills S. aureus by inducing cell leakage possibly due to flavonoids and anthraquinones contained in it. The extract should be further isolated and its active principles with potent antibacterial properties developed for therapeutic applications.
Investigation of the potential pharmacological mechanism of action of Danhong injection against chronic heart failure using a network pharmacol ogy based approach
Authors: Lin Ruzheng , Li Wei 
Published: May 2022

Purpose: To investigate the mechanism of action of Danhong Injection (DHI) in chronic heart failure (CHF).
Methods: Network pharmacology was employed to identify the bioactive compounds and targets of DHI in CHF. Bioinformatics analysis was used to examine the potential biological functions and pathways of the candidate targets, while molecular docking was conducted to evaluate the binding affinity of the ligand-protein complex.
Results: Based on data mining from public databases, 65 bioactive ingredients and 246 potential targets of DHI were identified, along with 786 CHF-related genes. There were 48 common targets between DHI targets and CHF-related genes, and a protein-protein interaction (PPI) network of common targets containing 42 nodes and 204 edges was constructed. The 48 common targets were considered as effector proteins exerting anti-CHF effects, and they were shown to be involved in multiple signal-transduction pathways and disease-related pathways by bioinformatics analysis. Most of these targets had protein-binding capability and were located in plasma membrane as well as extracellular regions. The biological process of these proteins was primarily associated with gene regulation, response to hypoxia, and heart development. Binding capability between these active ingredients and proteins was further validated by molecular docking simulation.
Conclusion: This study has shed new light on the pharmacological mechanism of action of DHI’s effects on CHF, thus offering fresh leads for additional research into DHI's potential to cure CHF.

Authors: Wang Yu , Li Chengling , Peng Keyun 
Published: May 2022

Purpose: To determine the efficacy and safety of locally-applied vancomycin powder injection as precaution against prosthetic joint infection (PJI).
Methods: A total of ninety subjects on admission in Department of Limb and Joint Surgery, PLA Medical Center, who underwent surgery for arthroplasty of knee and hip, were selected for this study. They were divided into two groups comprising control group (n = 45) given routine preventive antibiotic therapy as well as treatment group (n = 45) which received routine prophylactic antibiotics in combination with vancomycin therapy. PJI and the incidence of adverse reactions within 3 months after surgery were recorded. Body temperature of the patients was recorded with a thermometer. The number of neutrophils was measured by flow cytometry, while the expression levels of IL-6 and hs-CRP in peripheral blood were determined using enzyme-linked immunosorbent assay (ELISA) preoperatively and at 24, 72 and 168 h post- therapy.
Results: At 90 days post-therapy, there was obviously significant reduction in the degree of PJI in the vancomycin-treated subjects compared with control group (p > 0.05). Moreover, within 3 days, normothermia, lowered neutrophil population and downregulated expressions of Il-6 and hs-CRP were seen in the vancomycin group, when compared to control subjects (p < 0.05). However, there was no significant difference in the incidence of adverse reactions between the treatment and control groups after therapy (p > 0.05).
Conclusion: Topical application of vancomycin powder injection is safe, and regulates the body temperature of PJI patients in the short-term after surgery. Moreover, it decreases the levels of inflammatory indices. However, further clinical trials should be carried out prior to application in clinical practice.

Purpose: To investigate the anticancer effects of the extract mixture of Mori radicis cortex, Mori ramulus, Angelica tenuissima, and Inonotus obliquus extract (MRME), a new herbal preparation from Korea, on B16F10 cells.
Methods: The MRME was extracted with water. Cell Counting Kit-8 (CCK-8) assays and 4′,6- diamidino-2-phenylindole (DAPI) staining were used to investigate the effect of MRME on cell proliferation and apoptosis in vitro. The expression of p53, p-p53, and phosphorylated Akt (p-Akt) were analyzed by western blotting. Wound-healing assay was used to analyze cell migration.
Results: Based on CCK-8 and DAPI staining results, MRME inhibited the growth of B16F10 cells and induced apoptosis in B16F10 cells in a time- and dose-dependent manner (p < 0.05). MRME increased the expression of p53 and p-p53 and decreased the expression of p-Akt in a dose-dependent manner. MRME treatment inhibited cell migration and invasion (p < 0.05).
Conclusion: Mori Radicis Cortex Mixture Extract exerts anticancer effect by inducing the expression of p53 and p-p53 and decreasing the expression of p-Akt, which may benefit patients with malignant melanoma when used in combination with v-raf murine sarcoma viral oncogene homolog B1 (BRAF) inhibitors.
La mujer en la historia del cristianismo
Authors: Sánchez Herrero José 
Published: May 2022

A partir de los textos sagrados del cristianismo el autor analiza la relación de Cristo con las mujeres y pone en evidencia cómo estas pasaron a formar parte de su núcleo de fieles más cercanos. No olvidemos que ellas fueron las que estuvieron presentes en los momentos clave de su vida, los momentos de tránsito, como su muerte y resurrección. Los textos paulinos y las mujeres en la Iglesia primitiva son analizados y se convierten en paradigmas para comprender la evolución del papel femenino en el cristianismo hispano del siglo V al XVI. La última parte del artículo está dedicada al proceso experimentado desde el Concilio Vaticano II hasta nuestros días, destacando las reformas del papa Francisco destinadas a conseguir para la mujer un lugar, si no fuera posible en el orden sacramental, al menos en el orden ministerial y de gobierno de la Iglesia.
