In the context of globalization and the internationalization of international markets, mergers and acquisitions are becoming increasingly important for transnational corporations and national economies of countries as a form of internationalization, integration and the way to attract foreign investment. In the framework of this paper, the theoretical aspects of mergers and acquisitions have been analyzed, and the experience of Germany, China and Russia in attracting investments through mergers and acquisitions has been examined, and the success of this method for each country has been assessed.
This thesis focuses on the introduction of a process for the fracture toughness testing of epoxy resin systems, in the light of the linear elastic fracture mechanic approach. Based on the requirements of ISO 13586, SENB-specimen were designed and especially the precracking process was analysed and the tapping process was optimized by designing and testing a drop-weight device. After successful validating the test process using specimen made of Araldite LY556, the in uence of GNP loading on the fracture toughness was analysed. The pure epoxy showed a KIc of 0.73 MPap
m, being perfectly in line with the manufacturers datasheet. A peak in fracture toughness of 0.83 MPap
m was archived at 1 wt% and a loading rate of 10 mm/min, showing a decreasing trend as the loading is increased further. As the loading rate is increased, the fracture toughness reduces slightly for 0.5 wt% and 2 wt% GNP, but
drops signicantly for 1 wt% GNP obliterating the peak. The load vs. displacement curves showed quasi-brittle material behaviour. The fracture surfaces were analysed using SEM and while the neat resin did not show any features, did the reinforced samples show pattern of crack pinning in connection with bridging and pull-out. The resulting improvement is less signicant as observed by other researchers for larger GNPs. This is in line with the general idea, that small particles are not able to yield as high improvements, but the signicant decrease for higher loading rates is not observed or described so far. It is suspected that tests at lower loading rates (e.g. 1 or 0.5 mm/min) show an even higher fracture toughness.
Internationalization and business expansion appear to be the most challenging processes in business conduction today. Every step of the foreign market entry process and overseas operations establishment is full of obvious risks and hidden pitfalls. Theoretical background, multiplied with the vital practice, is playing the key role in such a complicated business process; such information can be used as a guideline by further market entrants and players. At present, Germany with its well-developed engineering industry represents a broad space for research of internationalization process in its different forms, as well as can show both successful and negative results of foreign market entries.

This bachelor thesis examines two main topics: Corporate Social Responsibility and Corporate Philanthropy as an integral part of it. It was written in order to prove the high importance of business philanthropy in today’s global market and to encourage companies to strengthen their CSR policy so as to contribute to the resolution of social problems. This paper reviews the theoretical framework of CSR, its evolution, types and theories relating to Corporate Philanthropy. Also it represents a comparative analysis of successful practices of corporate philanthropy in pharmaceutical and other global industries predominantly in Europe and USA. This work underlines competitive advantages and important socio-economic impact of CP and suggest recommendations for companies in developing their CSR activities. The subsequent paper is based on internet research using articles, presentations, reports and studies, websites and official legal documents.
