Cardiovascular diseases are the leading cause of death in the European Union. Therefore, the aim of the research is to investigate the effect of the active invasive ultrasonic vascular clearing systems on live human tissues and to use the relevant findings and the results obtained in the course of the research for the further improvement of the active members that are currently used in ultrasonic systems. In order to achieve the above stated aim, the following objectives were set: 1) To accomplish analysis of literature on the currently known effects of ultrasound on human tissues and waveguides currently being used for the purpose of vascular clearing. 2) To develop a multipurpose waveguide capable of operating in three directions and suitable for restoring the functioning of the blood vessels in an interventional way. 3) To develop a technique for the research of the cavitation process within fluids while mathematically modeling the waveguide of a newly designed structure operating within the tissue-confined fluid. 4) To investigate experimentally the newly designed and find out the effects it has on human tissues, and to determine the operational characteristics of the system under consideration. This work is carried out by using theoretical and experimental research methods. The theoretical studies were performed by using COMSOL MULTIPHYSICS computer software packages. . The experimental results were obtained by using the most up-to-date available non-contact laser measuring and other experimental equipment. An innovative waveguide of a unique shape has been designed for invasive clearing of blood vessels capable of generating the cavitation flow by means of inducing mechanical multidimensional vibrations of ultrasonic frequency. The waveguide under consideration is used within the ultrasound system for the elimination of vascular disorders in humans.

This paper addresses the concept of international trafficking in human beings in the international and EU legislation and reveals, how the concept had changed over time. It also analyses the evolution of the legal rule of trafficking in human beings, since its very adoption in the criminal law to the currently applicable legal rule, as well as assesses its compliance with the international and EU legal rule, and proposes certain improvements thereto. Objective and subjective characteristics of trafficking in human beings and characteristics constituting body of the crime, as provided for in Article 147 of the Criminal Code, are discussed in the second part of the analysis with a focus on recent changes to Article 147 of the Criminal Code. The author provides some insights into the difficulties related to application of the said legal rule and considers a few examples from the case-law. The last part of the thesis examines the connection of trafficking in human beings to other criminal offenses, namely, profiting from another person's prostitution, exploiting another person for forced labour or services, using another person's forced labour or services, etc. Lastly, the conclusions and suggestions for improvement of the regulatory framework are presented.

Climate change affects almost all economic sectors, just the impact of risks differs by sector, organisation, industry, and geography. One of the ways to mitigate climate change is to innovate and adopt financial instruments. Mandatory climate reporting can trigger an improvement in carbon performance because of legislative and societal pressure. Unfortunately, identifying and quantifying climate risks and opportunities seems to be a challenge for companies. The biggest issue for companies is that they have a lack of knowledge and skills to identify what scenarios could seriously disrupt the company's operations. Furthermore, there is no dedicated accounting standard related to climate-related matters, which leads to inconsistency in reporting. Just half of the reviewed companies included the results of their scenario analysis in their disclosures. In January, 2021, regulators released new reporting standards set by the Task Force on Climate-related Financial Disclosures (TCFD) requiring all commercial companies to develop more effective climate-related financial disclosures. Companies should assess which financial impacts are likely to impact their revenues, expenditures, assets, liabilities, capital and financing. Considering that, the main aim of the research was to develop a methodology to assess climate-related matters' effects on a company's financial statements. The objectives were created to highlight the issues related to climate change and their effects on financial statements, to analyse theoretical solutions to existing climate-related matters disclosure methods in the financial statements, to develop a methodology to identify climate-related matters disclosed in companies' financial statements, and to empirically investigate the effects of climate-related matters on a selected company's financial statements and make recommendations for other companies. Identifying risks and opportunities, stress testing, and scenario analysis are ways for a company to imagine plausible future worlds and plan for ...

Migration is a demographic, social, and psychological phenomen on very important for developed countries where international movement of population has a stronger influence on the country's demographic characteristics and economic indicators dependent on them. Migration processes started to receive more attention in the second half of the nineteenth century. After Lithuania regained its independence, migration processes became a hot topic and remain ed such to the present day. Much changed since 1990's. After regain ing independence and join ing the European Union in 2004, Lithuania started to see the phenomen on of massive emigration. Although rapidly growing migration is one of the features of a modern society, it can have negative effects, especially if the country is small and economically fragile. During twenty years of independence Lithuania lost about half a million inhabitants because of international migration. Migration theories state that migration is influenced by many economic, social, political, cultural, and psychological factors. Migration not only depends on different factors, but also is influenced by vary­ing economic and social conditions. This research report focuses on migration process changes in Lithuania during the period of 2003-2008 identifying the major labour market indicators in Lithuania, which have been strongly affected by international migration.

The authors have examined the large variation in adolescent fertility rates between and within countries to better understand the regional and individual factors underlying early childbearing. Using low spatial level data from the Lithuanian Census, they found that there is a high degree of regional differentiation within Lithuania, with differences of up to 20-fold between rates in different regions. Therefore, they investigated whether the regional differentiation in adolescent fertility rates is determined by different regional contexts or by the individual characteristics of teenage mothers. Surprisingly, the results of their regression models showed that the regional context did not have a large effect on adolescent fertility – the large differences between regions appeared due to the unequal spatial distribution of socio-economically disadvantaged teenagers. Their results also showed that women who had their first child during adolescence were statistically significantly different from those who postponed motherhood: those who gave birth during adolescence were more likely to belong to ethnic minorities (1.4 times more likely), receive government benefits (10 times), live in large households (10 times), and reside in rural areas (1.4 times). They were also more likely to terminate their education early, acquiring only a primary (7 times more likely) or lower-secondary (8 times) education. The study's findings suggest that public strategies and policies should address individual factors to reduce adolescent fertility rates and regional disparities. Teenage mothers should be supported to return to the education system as early as possible, thus preventing a further widening of the gap between their socioeconomic status and that of their childless peers.
