Djaxangirova, Gulnoza | Kurbanova, Nodira | Kurbanov, Bakhtiyor
In Uzbekistan, the main food product is bread, which is produced in various forms from local and imported wheat. Most of it is not studied by microelement analysis. The objective of this study is to quantify trace elements in locally produced wheat from various cultivated regions of Uzbekistan. Four different varieties of wheat are cultivated in Sirdarya, Tashkent region, Kashkadarya and Fergana were selected for analysis. Next, a comparative analysis of the elemental composition like iron, zinc, potassium, calcium etc., in the selected samples were studied. To carry out the above aims, an innovative research method was chosen, which is called improved instrumental neutron activation analysis. This method differs from others in its high accuracy in determining trace elements and its multi-element nature. Using this method, we can understand how insufficient nutrients are in baked goods made from wheat grain grown in Uzbekistan. Based on the results of the study, it can be recommended to enrich the soil with fertilizers high in iron and zinc. As a result, in turn, will have a positive effect on the health of the population, since today there is a shortage of the above listed elements. It was also revealed that the concentration of potassium and calcium in wheat cultivated in Uzbekistan is in a high state than other elements. Using the chosen method, two toxic elements were determined and according to the analysis for toxic elements, all four samples are recommended for consumption, as they do not exceed the permissible level for food safety.

Janpavle, Ilze | Īle, Una
In planning active leisure areas, the main emphasis is placed on the elements used in the infrastructure of childrenʼs playgrounds and recreational sports areas, their functionality, and compliance with various safety requirements in the public outdoor space. However, there are no uniform requirements for the aesthetics of the elements or the visually coherent inclusion of such infrastructure in the surrounding environment and existing infrastructure. The study aims to evaluate the impact of the infrastructure of active leisure areas on the visual quality of the public outdoor space and possible improvements by choosing alternative elements with a different visual design but similar functionality and to distinguish the main characteristic features for determining the visual quality of elements and characterize the impact on the surrounding environment. The research uses the descriptive or monographic method to collect and analyse the elements and functionality included in the surveyed territories in the summer and autumn of 2022, evaluating the aesthetic quality of the elements in active leisure areas in the public outdoor space of Riga and Tallinn. The studyʼs main results reflected several problems related to integrating active recreation areas into the surrounding environment. They highlighted issues related to the quality of the existing environment, which can be described as insufficient or low and which characterizes the planned development as coming into conflict with the existing environmentʼs aesthetic qualities or their absence.

This article presents the results of studies on biological samples collected from 640 swabs taken from dogs and cats across various regions of the Republic of Kazakhstan. These samples were part of a monitoring study on the spread of coronavirus among domestic animals. Total RNAs were isolated using the magnetic sorption method with the ALPREP kit and subsequently analysed with the ALSENSE-SARS-CoV-2 RT-qPCR kit. Real-time RT-PCR analysis revealed that 104 samples tested positive within 22–37 amplification cycles. These positive samples were then cultured in Vero cell lines to confirm the presence of the virus. The biological activity of the resulting virus-containing suspension was determined using the Reed-Muench method. During cultivation, one viral isolate with a biological activity of 5.83±0.08 lg TCID50/ml was obtained. A microphotograph of the virus was taken using an electron microscope to determine its size, shape, and structure, which confirmed its morphology corresponding to the Coronaviridae family. The data obtained further indicate that domestic animals can suffer from and carry coronavirus. It is becoming increasingly evident that the virus can infect and replicate in the organs of various farm and domestic animals.

Digital progress in the European Union is a catalyst for economic development. The COVID-19 pandemic significantly accelerated the pace of digitalization, thereby creating not only challenges for the European Union but also new opportunities for economic development in Europe. The present research focuses on an analysis of digital economy and society index scores for Latvia and Lithuania, comparing the performance of both countries with the European Union average. The research aims to identify the critical areas that hinder digital progress in Latvia and Lithuania. Accordingly, the digital economy and society index was analysed for the period from 2018 to 2023. The empirical part of the research includes a sociological survey, and the survey data were analysed in order to identify population needs for and experience in using digital technologies in Latvia and Lithuania. The survey involved 146 respondents. The research results allowed us to identify the critical areas for Latvia and Lithuania to focus on for further digital progress. Latvia and Lithuania both show high scores, well above the EU average, in the ‘digital public servicesʼ component, indicating that both countries have a high level of e-government users and widespread access to digital public services. The results of the sociological survey further confirm this, showing that a large majority of 84.25% of respondents in both Latvia and Lithuania use digital solutions in their daily lives.

Ivavičiūtė, Giedrė
In Lithuania, as well as throughout Europe, the areas of natural meadows and pastures are gradually decreasing due to the intensification of agriculture, leading to the ploughing of meadows and the consequent loss of valuable biodiversity, a crucial component of the landscape. The problems associated with meadow and pasture reduction is essential for informed decision-making, sustainable land management, the conservation of biodiversity and ecosystem services. Various methods, including comparative, analytical, statistical, and logical analysis, were employed in the investigation. The comparative study employed information from the Land Fund of the Republic of Lithuania covering the period from 2003 to 2023. The article also analyses the reasons and perspectives of the decrease in meadow and natural pasture areas. In 2023, meadows and natural pastures in the Republic of Lithuania covered 362,351.79 ha, constituting 5.55% of the countryʼs territory. From 2003 to 2023, the total area of meadows and natural pastures decreased by 135,439.55 hectares or 27.21%. From 2003 to 2023, in nine out of ten Lithuanian counties, the areas of meadows and pastures decreased. The most significant loss of these areas occurred in Siauliai County (36,828.33 ha or 59.02%), while the least loss was in Klaipeda County (141.05 ha or 0.34%). The decrease in meadow and natural pasture areas can be attributed to various factors: changes in land use, urbanization, climate change and other influencing factors. The area of meadows and pastures in Lithuania should increase by 87,000 hectares, and meadows and pastures in country would cover an area of 449,351.79 ha or 6.88% of the total area of the Republic of Lithuania.

Ivavičiūtė, Giedrė
The topic of this article is relevant because in Lithuania the assessment of the area occupied by plantations and green spaces has shown that the area standards do not meet the requirements and recommendations of the World Health Organization. Green spaces are regulated differently in different countries of the European Union. Lithuania has also developed a legal framework for the protection, management and establishment of new plantations and green spaces. However, this legal framework is improving and new laws are being added to it. Comparative, analytical, as well as statistical, and logical analysis methods were used for the investigation. The data of the Land Fund of the Republic of Lithuania for 2002–2022 were used for comparative investigation. The aim of this article is to perform an analysis of the change in the trees and shrubs greenery area of Lithuania in 2002–2022. In Lithuania, for example, trees and shrubs occupied 84,687.48 ha in 2002. In 2022, the plantation area amounted to 208,609.48 ha. From 2002 to 2022 the area of tree and shrub plantations in Lithuania increased by 123,922.00 ha or 146.33%. The analysis shows that in the period between the years 2002 and 2022 the biggest increase in the area of shrubs and plantations took place in Utena County (32,715.83 ha or 395.27%), but the smallest increase in Tauragė County (2,642.93 ha or 37.69%) and Marijampolė County (4,581.39 ha or 72.25%). The development of plantation areas has been positively influenced by the creation of an appropriate legislative framework and the implementation of plantation programs in counties and municipalities.

Vintere, Anna | Bartusevičienė, Inga | Aruvee, Eve | Rimkuviene, Daiva
Individuals’ emotional well-being is determined by several factors, including the ability to cope with daily stress and the ability to cope with various daily challenges. Ability of the management to provide favourable psychoemotional and psychosocial conditions within their team is particularly important. However, managers do not always have the knowledge and skills to lead their teams. For the development of the methodology, a study of the scientific literature on topical issue like healthy workplace was performed. The empirical part of the study is based on the results of the survey conducted Lithuania, Latvia, Estonia and Sweden within the Nordplus project ‘Dealing with anxiety during a pandemic to enhance adult well-being’ on the impact of COVID-19, as well as the training that would be necessary for the managers of companies or organizations to promote emotional wellbeing in the workplace. The comparative study was conducted from the perspective of both employees and managers. The results show that the impact of the COVID-19 pandemic on workplace and the well-being of employees was not strong for the respondents, depending mainly on the job position, the size of the organization and country. Managers and employees consider various psychological trainings essential.
