The Impact

The paper deals with geodetic and metrological activities in the field of length parameter, on the basis of which the uniformity and accuracy of measurements and gauges are ensured also in international extent. The historical role of surveyors in determining the basic unit of length is briefly described. Furthermore, the impact of the application of the laser tracker on the accuracy of determination of the characteristics of the geodetic length standard Koštice (Czech Republic) is evaluated. Based on laboratory tests performed in VUGTK and interlaboratory comparative tests with a leading laboratory in the length parameter in Veisala (Finland), the declared uncertainties of measurement of the VUGTK laboratory were confirmed. These are applied in the metrological traceability of the geodetic length base in Javoriv (Ukraine).

The Impact

This paper addresses the problem of describing the spread of COVID-19 by a mathematical model introducing all the possible control actions as prevention (informative campaign, use of masks, social distancing, vaccination) and medication. The model adopted is similar to SEIQR, with the infected patients split into groups of asymptomatic subjects and isolated ones. This distinction is particularly important in the current pandemic, due to the fundamental the role of asymptomatic subjects in the virus diffusion. The influence of the control actions is considered in analysing the model, from the calculus of the equilibrium points to the determination of the reproduction number. This choice is motivated by the fact that the available organised data have been collected since from the end of February 2020, and almost simultaneously containment measures, increasing in typology and effectiveness, have been applied. The characteristics of COVID-19, not fully understood yet, suggest an asymmetric diffusion among countries and among categories of subjects. Referring to the Italian situation, the containment measures, as applied by the population, have been identified, showing their relation with the government's decisions; this allows the study of possible scenarios, comparing the impact of different possible choices.

This article focuses on the role of spatial dynamics in effectuating the integration of two different sets of land surveying techniques. During the later stages of the Qing-Zunghar wars of the 1690s, the Kangxi emperor (r. 1661-1722) repeatedly asked French Jesuit missionaries, who had been sent to China in 1685 under the patronage of the French King Louis XIV, to join his imperial campaigns targeting the Khalkha-Mongolian borderlands. In the shadow of these imperial journeys, missionaries systematically determined latitudes with Paris-made instruments while Qing officials measured road distances all along the way with graduated ropes. A next step in the evolution of imperial cartographic practice came after the Qing- Zunghar wars had come to an end, when an all-out effort was launched by the emperor to integrate the newly conquered Khalkha Mongols and their lands into the Qing polity. As part of the effort, missionaries were asked to produce a map of the new frontier by integrating European and East Asian practices, which led to the discovery of a technical incompatibility. In 1702, the problem was solved by the precise measurement of the terrestrial degree and, immediately after, the restandardization of the Qing’s most basic unit of length, the chi 尺. Thus, I argue that the turn of the eighteenth century saw the crystallization of a new or hybrid Qing cartographic practice, driven by the need to explore the new Khalkha frontier. More concretely, I show how selected techniques as developed by the French Academy of Sciences were gradually absorbed into a pre-existing framework of Qing land surveying, a process that was shaped and facilitated by exchanges in via throughout the vast Mongolian frontier.

This study generally examines the influence of education, health, experience and government loans on farmers’ productivity in district Nowshera. Specifically, this study (a) finds out the role of socio-economic factors determining tomato production in district Nowshera and (b) estimates technical efficiency of the tomato farmers in the area. Primary data has been collected through a field survey from 61 tomato producers of selected villages of the district. The results reveal on the average tomato farms in the study area are 95% efficient, indicating a 5% potential for the farms to attain the maximum output level while the range of efficiencies was 89% to 99%. Moreover, the results also showed education, health, experience and government loans playing a significant role in the determination of the tomato production. On the basis of these results, it is suggested that government increase spending on education and health as such loans can play an important role in the tomato farming in district Nowshera.

The study focuses on the analysis of labor productivity in Polish agriculture in 2005 and 2016 in comparison to selected EU-15 countries (group 1) and some countries that joined the EU after 2004. In group 1, Austria, Belgium, Denmark, the Netherlands and Germany are included, while in group 2 - the Czech Republic, Slovakia, Lithuania, Latvia and Hungary. The analysis particularly considers the role of large farms, the size of which was contractually agreed at 30 ha of UAA. The aim of the study was to determine the impact of large farms on the level of labor productivity in total farms and to determine the possibility of reducing the differences between labor productivity in Polish large farms in relation to analogous farms in EU-15 countries, and determining whether changes occurring in Poland differ from those occurring in large farms in other post-socialist countries. In both groups of countries there was a decrease in the number of farms and an increase in labor productivity in agriculture in general and in surveyed classes in large farms. In the countries of group 2. the rate of labor productivity growth was higher than in group 1. However, it slightly reduced the differences. Labor productivity in agriculture in the countries of Group 1 was significantly higher than in Group 2. The increase in the number and share of large farms in the structure of farms was positively correlated with labor productivity in agriculture.

Hardness Values

For critical structures in the oil and gas refining, petrochemical and chemical industries, it is necessary to determine the value of mechanical characteristics. In the present paper we consider issues related to the determination of the mechanical characteristics of structural materials using compact samples. Basically, current values ​​of the mechanical properties of materials are determined by measuring hardness using existing empirical dependences that combine hardness values ​​with yield limit and tensile strength values. But such dependencies are not universal and require experimental verification. The need for compact samples application occurs during determination of the reasons of equipment failure, when the size of a fragment of broken down equipment does not allow producing standard samples for traditional testing performance. The application of empirical dependencies for determination of hardness mechanical characteristics is complicated by the fact that it is necessary to take into account the degree of the material degradation. This, in its turn, requires additional studies. The key issue in determining the accuracy of measurements on compact samples is the role of the surface in the formation of fracture focal points. The experiments were carried out on thin steel samples and the mechanical characteristics were determined on Instron 8801 dynamometer unit. It was shown that in case of increase of thickness of the samples that underwent tension testing, the fracture work varies according to the power law.

Confectionery Product

Chocolate is the most staple and consumed confectionery product in Russia and the world. The determination of the beneficial properties of such a product as chocolate is an important and regular process of food institutions in every country, since new lines of already well-known manufacturers and new manufacturers with an innovative assortment are added to the retail assortment. Today, it is very relevant and important to understand the impact of new products on human health. In this regard, in order to provide complete information on a specific product, it is necessary to know its composition, ingredients and their effect on the body separately and within the framework of a specific product. Along with its beneficial properties, chocolate can also affect health negatively. It is necessary to understand the mechanism of the effect of chocolate on human health when consumed and to assess the risks that may arise subsequently after its active consumption.

The Impact

This chapter identifies ways researchers, policymakers, therapists, lawyers, and couples should attend to the role of gender and gender dynamics facing same-sex couples upon divorce or relationship dissolution. When same-sex couples marry, gender roles associated with a particular vision of different-sex couples—in reference to which the legal institution of marriage developed historically—may be projected onto same-sex couples both socially and by judges adjudicating their relationship dissolutions, often in a manner conflicting with couples’ intentions and practices. Thus, couples consisting of two men and couples consisting of two women may be differentially affected. Gender and gender dynamics are likely to affect the bases for dissolution (e.g., whether one of the spouses committed adultery or whether there is a basis for annulment); the financial aspects of dissolution; and determination of child custody. The chapter suggests directions for future research regarding the impact of gender on the dissolution of same-sex relationships.

Problem and goal. Determination of the place and role of education in the national security system at the present stage based on the analysis of the foreign and Russian regulatory framework, as well as scientific literature on the subject of the study. Methodology. Through the analysis and parallel comparison of the main domestic and foreign regulatory legal acts in the field of security, the key transformations of the perception and vision of education as a factor of national security in foreign countries and Russia were identified, and the causal relationships between the development of the education system and national security were formulated. Results. The problems of national security in all their diversity are significantly related to the state and sustainability of the development of the educational sphere, the impact of which is long-term and has far-reaching consequences in the form of imbalances in the socio-economic, scientific and technological development of the country. Conclusion. The formalization of existing approaches to assessing threats to national security and the economic aspects of ensuring national security will allow us to propose a methodology for quantifying the costs of the education system as a whole (or only for higher education), necessary to optimize the impact of education on national security.

The article examines some effects from the first approbation of a two-tier proportional system with „flexible” lists in the local elections in Ukraine in 2020. In the comparative-regional context, the impact of the new system on the increase in the number of invalid ballots is analyzed and the percentage of voters who exercised the right to preferential voting for a particular candidate from the district list of the elected party is calculated. Hypotheses about regional differences in these quantitative parameters are formulated: in particular, the share of invalid ballots may be influenced by ethnolinguistic and urban factors. It was found that about 80% of voters who took part in the autumn 2020 vote exercised the right to preferential voting by entering the number of a particular candidate on the ballot – this unexpectedly high figure is in the context of other national cases using proportional systems with „flexible” or clean „open” lists. Particular attention is focused on the relationship between the two levels of the electoral system – the single closed and district flexible lists, and, accordingly, the balance of influence of voters and party leaders on the passage of candidates to local councils. This ratio was calculated for all oblast councils, and the material of the Kharkiv and Lviv oblast councils determined the empirical probability of changing the order of candidates in the district party lists under the influence of voters. Although supporters and lobbyists called the introduction of a new electoral system in Ukraine a model with „open” lists, the article identifies two key institutional mechanisms for significantly downplaying the role of preferential voting in the final determination of candidates. It is argued that according to the results of the personal distribution of seats among the candidates in the party lists, this model of „flexible” lists was closer to the pole of „closed” than „open” lists. Keywords: electoral systems, electoral lists, Electoral Сode of Ukraine, proportional electoral system, „flexible” lists, preferential voting, invalid ballots.
