Published: October 2022

The condition of the total fertility rate in Yogyakarta Province has tended to increase in the last decade. But there has also been a decline in the use of modern contraception. This study aims to study the determinant trend between fertility in the Province of Special Region (DI) Yogyakarta using the 2002/03 IDHS data and the 2017 IDHS with aggregate data for women of childbearing age 15-49 years. The results show that the pattern of marriage, the use and effectiveness of contraception, and the pattern of infertility during breastfeeding are intermediate determinants of fertility in DI Yogyakarta Province. Patterns of use and effectiveness of contraception are the main determinants of fertility in the two survey periods. The increasing marital index shows that the reproductive period of women in married status is getting longer and can cause them to be exposed to the possibility of giving birth to more children. The role of the use and effectiveness of contraception is still dominant in contributing to fertility decline. Therefore the use of contraception as a birth control still needs to be strengthened either through advocacy to stake holders in the local government.

Authors: Xie Feng , Zhang Ning , Chen Chenshu , Li Cheng
Published: October 2022

The lateral free vibration of micro-rods initially subjected to axial loads based on a nonlocal continuum theory is considered. The effects of nonlocal long-range interaction fields on the natural frequencies and vibration modes are examined. A simply supported micro-rod is taken as an example; the linear vibration responses are observed by two different methods, including the separation of variables and multiple scales analysis. The relations between the vibration mode and dimensionless coordinate and the relations between natural frequencies and nonlocal parameters are analyzed and discussed in detail. The numerical comparison shows that the theoretical results by two different approaches have a good agreement, which validates the present micro-rod model that can be used as a component of the micro-electromechanical system.
Links Between the Psychological Impact of Advertisement Breaking Stereotypes, Self-congruence and Brand Attitude
Authors: Lingytė Laima
Published: October 2022

Stereotypes are an integral part of the societal context, encompassing many different social and demographic groups. According to Bordalo et al. (2016), there are three broad approaches to stereotypes, one of which is sociological, most commonly used in the field of marketing research. From a sociological point of view, stereotypes are seen as fundamentally incorrect and degrading generalizations of group characteristics. Accordingly, breaking stereotypes in advertising is a reflection of social change and movements such as feminism and racial equality. It is no secret that advertising, as a sales promotion tool, is playing an increasingly important role in the social context, so the popularity of non-stereotypical advertisement such as 'femvertising' makes it necessary to study the effects of advertisement breaking stereotypes. An empirical study was conducted, to study the links between the psychological impact of advertisement breaking stereotypes, self-congruence and brand attitude.
Czy ekolingwistyka i geopoetyka mają szansę ukształtować nasze postawy?
Authors: Wojciechowska Justyna
Published: October 2022

The text briefly defines ecolinguistics and geopoetics as trends in contemporary humanities that give a living hope for shaping modern man’s attitudes towards the environment. The development of civilization is a good thing, but at the same time it carries a lot of threats. Ecological awareness is still something unnatural in the thinking of the average person and still requires awareness of the relationship between the quality of behavior of contemporary society and the quality of life of future generations. The text shortly mentions ecolinguistics and geopoetics as trends that allow to raise awareness, especially among students and young people. It should be emphasized that this important reflection is only a narrow part of the considerations on possible ways of shaping ecological awareness, as well as the trends themselves

The conducted research made it possible to reach and substantiate a number of conclusions. In particular, that contracts can be both public and accession ones, or only have signs of a public contract or an accession contract. At the same time, when concluding such contracts, the freedom of contract is significantly limited, both with regard to the possibility of the entrepreneur refusing to conclude a public contract, and with respect to the parties joining the accession contract or public contract, who are deprived of the opportunity to determine the terms of the contract. At the stage of concluding a public agreement and an accession agreement, only one of the parties has freedom of action regarding the conclusion.
 It is substantiated, that the freedom of contract can be limited by a standard contract, which can be both recommended at the level of subordinate legal acts and developed by any participant in civil legal relations. When concluding a preliminary contract, the freedom of the parties is limited temporarily and partially

The purpose of the article is to study European electoral and referendum law. In order to achieve it, it is necessary to solve the following tasks: disclosure of the nature of European electoral and referendum law; analysis of existing European legal standards in this field; highlighting the trends and regularities of the development of European electoral and referendum law in modern conditions. The methodological basis of the research is general scientific methods, in particular, dialectical, systemic, synthesis method, etc., and special legal (comparative-legal, historical-legal, formal-logical, structural-functional, legal semiotics, etc. .) methods of scientific knowledge. Their combination made it possible to comprehensively analyze the essence and peculiarities of European electoral and referendum law, to find out the trends and prospects of their development in modern conditions.
With the creation of an extensive system of international legal standards of the universal and regional (mostly European) levels, which guarantee the rights of citizens to participate in elections and referendums, the active functioning of the Council of Europe, the OSCE, the EU, the traditional democratic institutions of elections and referendums are marked by significant modernization and standardization. Along with the development of electoral and referendum law and relevant legislation at the domestic levels, the formation of European electoral and referendum law is observed. Undoubtedly, thorough studies of their nature and essence, subject-functional and other characteristics, mechanisms of implementation of existing European legal standards in this field, etc., are necessary. The risks and threats, associated with armed aggression against Ukraine, and the re-creation of classic institutions of people's power, for the improvement of which the efforts of democratic states and, in recent decades, international organizations have been concentrated, force the development of effective tools for countering and preventing manipulation of elections and referenda, establishing responsibility for such acts, increasing universally binding (normative) acts, along with "soft law" acts in this area

Along with renewable energy and hydrogen, gas hydrates may become the most significant energy resource in the coming years. The reserves of gas in the hydrate state exceed all the combined world reserves of traditional energy resources. At the same time, the gas hydrates properties in the conditions their natural occurrence in the composition of hydrate-containing rock cause significant difficulties in their extraction. In this regard, the industrial use of colossal renewable gas resources in the gas hydrate state is just beginning. Based on this, the methods of developing gas hydrate deposits are the object of research. Based on the analysis and generalization of the currently known examples results of experimental and industrial development of gas hydrate deposits, as well as the results of studying the hydrate-bearing rocks properties, an assessment of the prospects for the industrial implementation of gas hydrate deposit development methods is given. Extraction of methane from gas hydrate deposits causes difficulties due to their solid form. Existing promising methods of their development involve the dissociation of gas hydrate into gas and water.
Currently implemented research and industrial development projects of gas hydrate deposits have shown a number of problems related, first of all, to the instability of the hydrate-bearing rock after dissociation of the gas hydrate (at the same time, in the vast majority, the natural gas hydrate becomes metastable and weakly cemented). Therefore, there is still no commercially attractive technology for obtaining natural gas from gas hydrate deposits. At the same time, the depressurization method is considered the most promising. Based on this, the improvement of the technology of influence on the hydrate-bearing rock for the natural gas extraction should concern the provision of the rock removal the into the well. At the same time, effective and competitive development of marine gas hydrates deposits can be realized only if taking into account the geological features of the distribution of hydrate-bearing rocks, as well as the gas hydrates properties in their natural occurrence.
Improved methodology development for assessing the reservoir collector properties by the quantitative reservoir characterization tools
Authors: Martus Olena , Petrash Oleksandr
Published: October 2022

The object of research in the paper is the process of fluid transfer through the pore space of the reservoir rock. In this paper, using an expert method, the shortcomings of the Ukrainian methodology for assessing the reservoir properties of the reservoir were highlighted. In particular, the sources of uncertainty accumulation in determining the absolute values of the reservoir's filtration parameters have been identified. The existing problem is that the algorithms of actions, which are the basis of the Ukrainian method of assessing reservoir properties, introduce a significant degree of uncertainty into the assessment results.
In order to reduce uncertainty, the introduction of the concept of a representative elemental volume is considered when conducting laboratory research and the construction of a three-dimensional digital model of this elementary volume. It is suggested to improve the Ukrainian method of assessing the collector properties of the deposit based on current Western research.
It was established that the standard methods of assessing the reservoir properties of the deposit are a source of accumulation of uncertainty in the development of technological documentation for the development of the deposit. The work is aimed at the development of an improved methodology for assessing the collector properties of the deposit. It is proposed to add to the action algorithm the stage of determining the representative volume of the sample, building its three-dimensional model, and digitizing it. At the final stage, the connectivity of the pores inside the sample is determined using the Minkowski function to improve the quality of the project documentation for the development of deposits. Guidelines have been developed to improve standard methods for assessing the collector properties of the deposit. The use of an improved methodology for assessing the reservoir properties of the deposit leads to a significantly lower degree of uncertainty and helps to form a more reliable picture of the operation of the reservoir at the design stage of its development. The presented study will be useful for the engineering personnel of foreign contractor companies, as it justifies the need to collect additional core material and sets the quality criteria of the information obtained about the collector properties of the deposit.

One of the important problems of the oil and gas industry is the decrease in the production characteristics of wells in fields that are at the final stage of development. In addition, the drop in well production below their potential and the decrease in hydrocarbon recovery factors are often due to the deterioration of the reservoir properties of rocks in the process of drilling in productive formations, well workover, as well as the imperfection of production processes and means of their implementation.
The object of research is the technology of treatment of the bottomhole formation zone with non-acidic systems based on ammonium salts for the intensification of hydrocarbon production.
The paper considers a number of methods that allow solving the above problems, taking into account their complexity, efficiency and duration of the positive effect of processing. The main acid methods of influencing the bottomhole formation zone and their modifications are analyzed. The authors, using the results of the research and experience gained, proposed a non-acidic system of chemical treatment of oil and gas wells based on ammonium salts. Their influence on the rocks occurs more long-term and does not lead to the destruction of reservoirs.
During the research, physical, chemical, physicochemical methods and techniques developed by the authors for processing and analyzing field data, statistical methods for processing experimental studies were used. Modeling of deep processes was carried out on the installation developed and created by the authors.
The mechanism of interaction of ammonium salt solutions with terrigenous and carbonate rocks is revealed. Experimental studies have confirmed and theoretically substantiated the effectiveness of the use of ammonium salts to improve the filtration characteristics of reservoirs.
The effect of ammonium salt solutions on the change in the permeability of sandy and carbonate reservoirs in the Dnipro-Donetsk depression (DDD, Ukraine) has been studied. And also a mathematical model of the process of increasing the permeability of rocks during their dissolution by the studied chemical reagents was created. The mathematical model is available for its wide application in the practice of technological calculations and designing measures for the stimulation of oil and gas production.
