The master thesis first deals with definition of business contractual relationship (sources, formation, freedom of contract) and indicates ways of resolving disputes arising from it within the Czech legal code. Through defining the concept of cross-border element the master thesis attains on how to resolve business disputes over contractual obligations at the EU level. Core topic of thesis deals with jurisdiction in commercial matters, the law applicable to contractual obligations, alternative dispute resolution as well as the recognition and enforcement of judgements or of different rulings. The last part of the thesis deals with a practical procedure which shows how to resolve dispute between domestic businessman and foreign businessman via legal proceedings.

Presented thesis deals with the evaluation of air quality in Ostrava industrial area, especially with regard to highly concentrated suspended particles and sorbed on them toxic polyaromatic hydrocarbons. Their above-limit concentrations are the main cause of negative effects on the health of humans and other organisms in one of the most outstanding European "hot- spot"regions, in the industrial agglomeration of Ostrava. The first part of the work is devoted to the evaluation of pollutant concentrations and contributions of identified types of air pollution sources in the wider influence area of a large industrial source in the Ostrava region. It was confirmed the concentrations of all pollutants show very significant inter-seasonal differences between the warm and cold parts of the year. The measured concentrations of PAHs in the cold season were 3 to 5 times higher than in the warm season. Less pronounced differences in concentration levels were seen between day and night samples. The air-pollution load was highest at the Radvanice site, compared to Vratimov and the background area of Poruba. The pollution caused by suspended particles originating from the emissions of the industrial complex in the annual scale contributes significantly to the resulting air quality image on the site, but is not an exclusive source. Other identified sources of the contributions to the PM2.5 concentrations are regional sources and operating seasonally sources (local heating). The second part of the thesis is an assessment of the character and regularities of air mass transmission in the ground-level layer of the troposphere in the Czech-Polish border area, as regional and long-range pollution transport plays a significant role, manifested in the resulting reduced air quality. The contribution of cross-border pollution sources is an important component of often alarming concentrations of atmospheric pollutants, especially during winter smog situations. It was shown within the northeast steady flow is dominated by the shift of higher concentrations of suspended particles from Poland to the Czech Republic. On the other hand, with the opposite prevailing direction of steady flow, particle concentrations on the Polish side of the territory are not increasing dramatically. At least half the year there are situations with variable wind direction, or low flow velocities during which the entire area on both sides of the border there are maximum concentrations of particles, including sorbed polyaromatics with the most serious health effects.

This master thesis deals with the characteristics of cross-border mergers, particularly from a legal and tax perspective. The first part defines the basic concepts and legislation, which is related to the cross-border mergers. The second part deals with the analysis of cross-border mergers, in which participated Czech companies. The third part treats the selected states in terms of tax systems. From analyzed states is chosen the most profitable tax system for Czech companies considering cross-border merger.

Town-twinning is a way of international cooperation between self-governments at the local level. The town-twinning is based on regular meetings of town representatives and citizens. The other type of international cooperation is the cross-border cooperation that points at common solution of problems in particular border area. The main aim of the town-twinning is information and experience exchange, arrangement of common cultural and sport events, school cooperation and language skills improvement. Thanks to the involvement of citizens in town-twinning activities, the mutual prejudices are eliminated and relations improved. The diploma thesis analyses the town-twinning between Prague and Nuremberg (Nürnberg), Pilsen and Regensburg, Domažlice and Furth im Wald. Thanks to the partnership, the towns and cities can advance their own interests in foreign policy by methods of public diplomacy and paradiplomacy regardless the relations between country governments. The improvement of international relations thanks to the town-twinning can be represented by the relationship between the Czech Republic and the Free State of Bavaria, where the twin towns were constituted without regard to the official policy of the country or the federal state. These contacts at the governmental level were very influenced by...

The thesis focuses on current diversification scenarios in the field of gas supply the Visegrad Group (V4) and the Russian Federation relying on the model of asymmetrical interdependence. Russian Federation, the main supplier of natural gas to this region, has lost its status of a reliable partner due to the gas wars with Ukraine in 2006 and 2009, which have negatively affected the supply of natural gas to the EU countries. The research focuses on the current diversification options of V4 countries related to their suppliers and supply routes with respect to their relationship with the Russian Federation; the diversification options for the purchasing markets of the Russian Federation are also analyzed. The author validates the hypothesis that energy relations among the Visegrad countries and the Russian Federation in the field of gas supply are largely controlled by the asymmetric interdependence that is currently exacerbating tensions among the set actors. Current diversification scenarios are presented and evaluated, with the aim of assessing the importance of the projects with regard to actors' energy security. Keywords: interdependence, energy security, diversification, gas supply, gas interconnector, V4, Energy Union, Russian Federation, Nord Stream II, LNG

The aim of this PhD thesis is to analyse the current status of European insolvency law and with the help of both national and European judicial decisions put together an overview of practical obstacles that insolvency courts, debtors, creditors and insolvency trustees across Europe are facing when dealing with cross-border insolvencies. At the very core of this topic stands the European Insolvency Regulation ("EIR") which was adopted in 2015 and is effective within the member states as of June 2017. Since this regulation was put together as a recast of its predecessor, i.e. the original insolvency regulation adopted in 2000 and effective as of 2002, naturally this research is oriented at comparing the two legislative acts and mainly assessing whether or not the recast EIR managed to overcome some of the inconsistencies in the wording of the original EIR, often resulting in conflicting interpretations and a great deal of preliminary rulings filed with the Court of Justice of the EU. Apart from looking into good old instruments of private international law such as the scope, the jurisdiction, the choice of law and the recognition and enforcement rules governed by the EIR, this thesis also focuses on topics that are very bankruptcy-specific and dissimilar to anything we know from other fields of law....

Materials scientists from Ústí nad Labem and Dresden met in June of 2022 for the first joint PhD Conference on Material Science, with the special focus on biologization, nanotechnology and simulation. The conference aimed to encourage interdisciplinary exchange between Čzech and German research institutes and promote transnational cooperation on an international level along the Saxon- Čzech border. Due to the restrictions caused by the corona pandemic, several attempts were necessary before the conference, which was first planned in 2020, could finally take place for the first time in 2022. The conference could take place in presence, which was seen as a big plus by all participants, especially as it was the first meeting in this German - Čzech context for most of the participants. The attending scientists (about 60) met at the Institute of Material Science of TU Dresden in Germany for the first half of the week before the conference moved to the faculties of Science and Environment of the Jan Evangelista Purkyně University UJEP in Ústí nad Labem in Čzechia. The organized activities ranged from scientific presentations of current PhD projects and research topics, lab tours in the participating institutions, come-together events such as a guided tour at the dye collection of the TU Dresden and a hiking trip to Bohemian Switzerland. The conference was funded by INTERREG VA Saxony - Čzech Republic - a cooperation programme of the Elbe/Labe region. All participants - PhD students, scientists and staff members of the participating institutions - enjoyed this opportunity to build individual and new contacts, exchange information on current research topics and methods, find starting points for future collaborations between the different research areas and institutions and also discuss the similarities and differences between the German and Čzech research landscape.

The PhD thesis "Current Issues in International Insolvency Law" aims to describe and draw attention to the moments that, in the opinion of its author, have had the strongest impact on international insolvency law so far. As such it is chiefly devoted to the analysis of existing regulation in the area of European insolvency law (which is principally based on Council Regulation (EC) No 1346/2000 of 29 May 2000 on insolvency proceedings - the "Old Insolvency Regulation" - and Regulation (EU) 2015/848 of the European Parliament and of the Council of 20 May 2015 on insolvency proceedings - the "New Insolvency Regulation"), and also provides a selection of the relevant case law which has over time significantly changed the way in which specific issues and instruments related to this area are viewed. To do justice to the complexity of the subject matter, the thesis also discusses the determination of jurisdiction in cross-border insolvency proceedings and recognition of the effects of foreign insolvency proceedings in relations between EU and non-EU countries. The main aim of the thesis is to answer the following questions: which legal documents have had the strongest impact on the current form of international insolvency law; whether and how the interpretation of the concept of centre of a debtor's main...
