Abstract. Steponas Kolupaila (1892–1964) was an important figure in 20th century hydrology and one of the pioneers of scientific water gauging in Europe. His research on the reliability of hydrological data and measurement methods was particularly important and contributed to the development of empirical hydrological calculation methods. Kolupaila was one of the first who standardised water-gauging methods internationally. He created several original hydrological and hydraulic calculation methods (his discharge assessment method for winter period was particularly significant). His innate abilities and frequent travel made Kolupaila a universal specialist in various fields and an active public figure. He revealed his multilayered scientific and cultural experiences in his most famous book, Bibliography of Hydrometry. This book introduced the unique European hydrological-measurement and computation methods to the community of world hydrologists at that time and allowed the development and adaptation of these methods across the world.

There are two different forms of property tax systems: value-based tax, which is used in most countries of the world, and area-based tax, which is used mainly in Central and Eastern Europe and developing countries in Africa. Area-based property tax provides more stable and predictable budget revenues. It is simpler to administer and scores worse on equity grounds from the perspective of the ability-to-pay principle of taxation. Against this background, Israel’s property tax system, known as Arnona, is complex, spatially diversified, and causes a lack of uniformity that leads to tax distortion. This paper’s primary purpose is to identify the weaknesses of Israeli property tax from 1997 to 2017 and indicate how to improve the property tax system. This paper is based on case studies from four of the most important cities in Israel: Tel Aviv, Jerusalem, Haifa, and Beersheba, which have four different measurement methods for calculating property tax. Unique data were collected from the Israel Central Bureau of Statistics. According to this analysis, it was found that there are substantial differences in property tax between the four cities over the two decades analyzed. The main weakness is the lack of uniformity of the taxation system; the solution is to unify the measurement of real estate area for tax purposes using drone technology.

In the modern era, it would be like glorifying the media to include every media related to human life from fingernail to fire. It is the medium that has the ancient ideology and values ​​of society as popular with globalization and modern thought stream The society, which is inhabited by the rajas, has also been plunged to the present day, seeing the reach and impact of media in particular, a frazzled Schmimiya state has been born, especially in order to achieve the concept of global global culture of Mishwa. It is from these media that we can see the news of events at the far end of the world, as far as music is concerned, it is possible that we can cope with many ages, ages and lives. When it is achieved in its present form, in the same continuous stream of time, it is infectious, sometimes Pallimat and Sushobhamat are the modern communication mediums in this stream are also pushing it deeper.Achayat Sharangadei has said in his famous book, Song Ratnakaresh आधुमनक काल में मानि जीिन से संबंमधत हर क्षेत्र को नख से मशख तक प्रभामित करने िाले संचार माध्यमों को ममहमादृमंमित करनाए सूरज को मदया मदखाने जैसा होगा द्य यह िह माध्यम है मजसने िैश्वीकरण ि आधुमनक मिचार धारा से लबरेज समाज के सार्थ ही पुरातन मिचारधाराए मान्यताओं ि रीमत ररिाजों से सराबोर समाज को भी तह तक प्रभामित मकया है द्य िततमान समय में संचार माध्यमों कीए मिशेषकर मीमिया की पह ंच और प्रभाि को देखते ह ए ही एक फ्रेज़ श्मीमिया स्टेटश् का जन्म ह आ है द्य मिशेषकर मिश्व के श्ग्लोबल मिलेजश् की पररकल्पना को प्राप्त करने में सबसे महत्िपूणत हार्थए इन्हीं संचार माध्यमों का हैए इन्हीं की बदौलत हम कोसों दूर की क्याए मिश्व के दूरस्र्थ छोर की खबरोंए घटनाओं का उसी पल अिलोकन कर सकते है द्य जहां तक संगीत का सम्बन्ध हैए यह सित मिमदत है मक अनेकों युगोंए कालोंए ि पररमस्तमर्थयों का सामना करते ह ए यह अपने िततमान स्िरुप को प्राप्त ह आ है द्य समय की इसी सतत प्रिामहत धारा में कभी यह संक्रममत ह आए तो कभी पल्लमित ि सुशोमभत द्य इसी धारा क्रम में आधुमनक संचार माध्यम भी इसे गहरे तक प्रभामित कर रहे है द्यआचायत शारंगदेि ने अपने प्रमसद्ध ग्रन्र्थ श्संगीत रत्नाकरश् में कहा है

The radical aesthetic of the historical avant-garde movements has often been explained as a reaction to the catastrophic experience of the First World War and a denouncement of the bourgeoisie’s responsibility for its horrors. This article explores a blind spot in these familiar interpretations of the international avant-garde. Not only the violence of the World War but also the experience of a worldwide deadly pandemic, the Spanish flu, have moulded the literary and artistic production of the 1920s. In this paper, I explore this hypothesis through the example of Mário de Andrade’s famous book of poetry Pauliceia desvairada (1922), which I reinterpret in the light of historical studies on the Spanish flu in São Paulo. An in-depth examination of all parts of this important early opus of the Brazilian Modernism shows that Mário de Andrade’s poetic images of urban coexistence simultaneously aim at a radical renewal of language and at a melancholic coming to terms with a traumatic pandemic past.

Experts in artistic gymnastics are constantly analyzing the outcomes of the gymnasts' performance at world and continental championships. However, the analyses cover only the assessment of the final scores of athletes and their ranks. There is a lack of research focused on the structure of routines and components of the scores obtained for the performance of combinations. The purpose of this study was to determine the content of competitive programs performed by the finalists of the World Championship Uneven Bars 2019 and to identify areas for the exercise development in this kind of all-around events on the eve of the Olympic Games. Methods and organization of the research: we carried out the analysis of video materials of the International Gymnastics Federation (FIG), the analysis of the competition rules for the current Olympic cycle, additional newsletters, and scientific instructional literature. We used an expert assessment method to identify the components of competitive combinations. Research results. The study determined quantitative indicators of the content of gymnast combinations on uneven bars (the number and difficulty groups of elements, including jumps and dismounts, modal and frequently performed elements, connection value bonus). We have revealed the trend for reduction of the total number of elements of competitive routines. It occurs due to reduction of the number of binders (“dilution”) elements, reduction of the number of elements of difficulty groups below 0.4 points, and increasing number of flight elements performed in a “cascade” way. We have revealed the trend for the use of elements of F (0.6 points) and G (0.7 points) difficulty groups in competitive combinations of the strongest gymnasts, which characterizes a significant increase in the coordination complexity of the programs and increases the requirements for the training of gymnasts. Conclusion. The research outcomes can provide the basis for predicting competitive programs on uneven bars at the upcoming Olympic Games, making amendments to the system of training gymnasts and the content of combinations to increase competitiveness at major international competitions, as well as making competition rules proposals for the next Olympic cycle.

Подтопления урбанизированных территорий, когда вода в периоды ливневых дождей поднимается на поверхность, затапливая улицы и подвалы, наблюдаются достаточно часто. Происходят они по разным причинам или их совокупности. Перечень мероприятий для сокращения количества таких подтоплений в мировой практике отработан. К ним можно отнести мероприятия, направленные на уменьшение коэффициента стока водосборных площадей, а также на увеличение свободных регулирующих объемов сетей и коллекторов и т. п. Однако оценка их эффективности в Российской Федерации затруднена в связи с тем, что нормативный метод гидравлического расчета предусматривает учет значений периодов однократного превышения расчетных интенсивностей дождей p, который указывает, с какой периодичностью переполняются сети. Но этот метод не отвечает на вопрос, с какой периодичностью pp происходят затопления территорий в результате выхода воды на поверхность. На примере Санкт-Петербурга приведен расчетный метод для определения среднегодового числа затоплений, а также результаты оценки эффективности мероприятий, направленных на их сокращение. Flooding of urbanized areas happens quite often, while, during periods of heavy rains, water rises to the surface flooding streets and basements. Flooding occurs for different reasons or due to their combination. The list of measures to reduce the flooding rate has been worked out in the world practice. These include measures aimed at reducing the runoff coefficient of drainage areas, as well as increasing the spare regulating capacities of the networks and sewers, etc. However, evaluating their effectiveness in the Russian Federation is complicated by the fact that the standard method of hydraulic calculation provides for taking into account the values ​​of the periods of one-time excess of the calculated rainfall rates p that indicates the overflow rate in the networks. However, this method does not determine the rate pp of area flooding that results from the water spills. Through the example of St. Petersburg, a calculation method is presented for determining the average annual number of floods, as well as the results of evaluating the effectiveness of measures aimed at reducing them.
