Rapid depletion of easy-to-access fossil fuel, predominantly, oil and gas resources has now necessitated increase in need to develop new oil and gas sources in ever more remote and hostile environments. This is necessary in order to explore more oil and gas resources to meet rapidly rising long-term energy demand in the world, both at present and in the nearest future. Arctic is one of these harsh environments, where enormous oil and gas resources are available, containing about 20% of the world total oil and gas, but the environmental conditions are very harsh and hostile. However, virtually all the facilities required for the exploration and development of this new energy source are constructed with metals as well as their alloys and are predominantly joined together by welding processes and technologies. Meanwhile, due to entirely different environment from the usual moderate temperate region, conventional welding technologies, common metals and their alloys cannot be applied as this Arctic environment demand metals structures with very high toughness and strength properties under extremely low temperature. This is due to the fact that metals transit from ductility to brittleness as the temperature moves toward extreme negative values. Hence, this research work investigates and presents the advanced welding technologies applicable to Arctic metal structures which can give satisfactory weldments under active Arctic service conditions. .

The Internet and other new information and communication technologies (ICTs) have become an integral part of most Western societies, from the perspective of both individuals and organizations. In this dissertation the evolving role of the Internet and other new ICTs in Finland over the past decade is studied from the perspective of disparity. The ICT disparities are seen to be constructed from two interconnecting elements, access and implications. The main goal of this dissertation is to examine how access, different user purposes, as well as implications, reflect disparities among different socio-demographic and socioeconomic population groups. For the purposes of this work, four research studies, each with its own, specific topic, were constructed. According to the results, age is clearly the most significant element associated with both access and implications for the new ICTs in Finland. Although other examined factors were also significant, they were often associated with individual research topics. In addition, the dissertation will also provide new research elements for future reference.
