The article is devoted to the important topic: the impact of NGOs on the creating of urban space. We focused on the case of the Charity Organization Teple Misto Platform (which means “Warm City”) in Ivano-Frankivsk. This city is one of the province Ukrainian one where live about 200 000 people. However, with the help of initiative people who united around NGOs it became a progressive pleasant for investment city with creative projects and remarkable possibilities for the citizens.\u0000\u0000Methodologically, the study is based on Actor Network Theory the process of forming the urban space was investigate as the result of interaction different actors including NGO. From the point of view that every city has his own logic of development, “Teple Misto Platform” became an important element in the network, which form Ivano-Frankivsk urban space. The actor-network theory urges us to observe the principle of symmetry and consider the influence of different actors equally.\u0000\u0000Academic originality. The role of the non-government organizations in Ukrainian city has not traced correctly according to the real level of their influence. Many authors mixed the political parties and NGOs ignoring their differences and main points. However last searching (for example, by Zagoriy Foundation) showed the increasing role of NGOs in the Ukrainian society.\u0000\u0000Conclusions. During the research, we observed how important it is to have a common platform that acts as a ground and support for other, smaller initiatives. It is shown how from the activities of a few activists a force grows that is able to influence the formation of the development strategy of the entire city. This case and experience could be use with other cities from all over the world.","PeriodicalId":438406,"journal":{"name":"34","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128176119","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The author found that Anatolii Kralytskyi could read works and learn the ideas of Mykola Kostomarov concerning Ukrainian history and the national question. Firstly, the monk published his texts in the periodical literature of Galicia already in the early 1860s, where Kostomarov’s texts were simultaneously published. For the second, in 1875, Kralytskyi received a set of Kostomarov’s books from Mykhailo Drahomanov. Kostomarov’s arguments had become so attractive to Basilian that he publicly declared Kostomarov was the most significant historian of his time. The article ascertains that Kralytskyi used Kostomarov’s ideas to strengthen his arguments. He did so while being included in transmitting the Ukrainian population from the archaic “Old-Ruthenian” identity to the new one. At the same time, the author explains, these significant changes included a Russophillian stage in the Galicia and Zakarpattia.","PeriodicalId":438406,"journal":{"name":"34","volume":"99 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125231224","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods of artistic influence on readers were used in various combinations. Their use allowed to project the expected emotions, and, as a result, to popularize scientific facts and evoke patriotic \"we-feelings\".

This is a famous art publication \"From Ukrainian antiquity\" in 1900 and a rare album \"Motives of Ukrainian ornament\", which was published in the early XX century.\u0000\u0000The vast majority of Samokish's works were performed in his favorite battle genre. Thus, the result of Nikolai Semenovich's trip to the front of the Russo-Japanese War was the album \"War 1904-1905: From the Diary of an Artist\" published in 1908. . The magazine \"The Great War in Images and Pictures 1914–1915\" of 1915 included the artist's front-line materials.

Molecular mechanisms of platelet aggregation are actively studied by methods of molecular cell biology, biochemistry, applied physics, but the problem of modeling the dynamics of this process remains open. Mathematical modeling allows to establish quantitative indicators of aggregation kinetics, to analyze the results of scientific research and testing of blood samples in everyday medical practice. Known mathematical models of spontaneous reversible and irreversible platelet aggregation in a shear flow of different intensity are not suitable for analysis of data obtained by the most common laboratory method - light transmission aggregometry.\u0000\u0000Objectives. The aim of the work was to create a mathematical model of platelet aggregation that can adequately describe the reversible cell aggregation, in particular the disaggregation of platelets in suspension.\u0000\u0000Materials and methods. A mathematical model of induced platelet aggregation has been developed. The kinetic constants of the model were optimized by experimentally determined average platelet counts in the aggregate measured by light scattering. Kinetic curves of light scattering of platelet suspension during aggregation induced by physiological agonist ADP were obtained using a laser analyzer of platelet aggregation ALAT-2 \"Biola\".\u0000\u0000Results. The proposed mathematical model is suitable for modeling reverse aggregation of platelets due to taking into account the inactivation of cells using the time dependence and correction of the disaggregation term.\u0000\u0000Conclusions. The developed mathematical model complements the models of the dynamics of irreversible platelet aggregation and allows to analyze reversible aggregation. The model satisfactorily describes the experimental time dependences of the size of platelet aggregates obtained by light transmission aggregometry. The introduced additional parameter and the method of setting the term corresponding to inactivation have a much smaller effect on the dependences than the kinetic constants. Calculated by model and optimized according to experimental data at different temperatures rate constants allow to calculate the activation energies of the aggregation process. When using light transmission aggregometry data to optimize the model parameters, it is advised to pre-smooth the input data to remove noise caused by the inhomogeneity of the suspension.","PeriodicalId":438406,"journal":{"name":"34","volume":"123-124 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117142543","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Such tasks are important when designing new inconspicuous equipment.\u0000\u0000The purpose of the work. Consider the existing and suggest improvements in the method solving of the problem of electromagnetic wave diffraction on the complex shape object, which is located on some underlying surface. In this case, the change in the electromagnetic parameters of the underlying surface should not lead to the need to re-calculate the field scattered from the object.\u0000\u0000Materials and methods. The diffraction problem is solved for the complex shape object, which is located on the underlying surface. The surface can be characterized by dielectric (and magnetic) permeability, complex reflection coefficient or surface impedance. In order to determine the resulting field for an object located on an arbitrary surface, the scattering problem is solved for cases when the object is located above an ideally conducting surface and above an ideal magnetic.\u0000\u0000Results. A modeling technique for the scattering of the electromagnetic waves by the complex shape objects located above an underlying surface is proposed. Numerical experiments have been caried out in order to demonstrate the effectiveness of this technique.\u0000\u0000Conclusion. It is shown that the method proposed in the article allows to effectively calculate the contribution of different underlying surfaces in the resulting scattered field of the complex shape objects that are located on it. You do not need to simulate directly for an object over a specific surface each time. It is enough to carry out only three simulations: for an object in free space, and also when ideal conductor and ideal magnetic are used as the underlying surface. Formulas that allow to calculate the field scattered by this object for an arbitrary underlying surface are obtained.","PeriodicalId":438406,"journal":{"name":"34","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121220789","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
