The logistical activity of transport is one of the largest contributors to several environmental problems. One efficient and effective way to decrease the environmental impact from transports is to implement changes in the logistically related strategies and activities applied, such as the selection of transport suppliers. Consideration of the environmental aspect when purchasing transport servic

This thesis deals with various aspects of coordinated voltage control in electric power systems. It consists of an introduction and six papers. The introduction contains a summary of the thesis and tutorials on voltage control and the search methods that have been applied. The first part deals with the coordination of cascaded tap changers in radial distribution feeders. A tuning rule for the con

In most sociological paradigms the importance of human interaction for the understanding of societies, is a well established fact. In this study, the focus is the interaction between human beings and material things as it is occurring in practice. Such an approach with its important consequences for understanding both social life and self, is often overlooked in studies within the field of sociolo

Diabetes - the imbalance in glucose homeostasis is partially caused by loss or dysfunction of pancreatic insulin producing β cells or development of insulin resistance. In Type 1 diabetes β cells are destroyed in the process of an autoimmune attack, whereas in Type 2 diabetes, islets produce insufficient amounts of insulin or the insulin cannot be used adequately. So far, the most promising therap

When attention is drawn to the recovery of resources within waste, the amount and types of waste disposed of at landfills change. A waste management system based on separate kerbside collection, sorting, recycling, and pretreatment with material and/or energy recovery produces new residues, which finally end up at landfills. This is the case in, for example, the US and the EU. As a possible result

In northern Scandinavia and other cold regions, urban drainage systems are often unable to cope with the high volumes of melt water which can be sustained for several weeks. High waste water treatment plant inflows, combined system overflows and low water quality are a few problems associated with snowmelt. However, reports detailing urban snowmelt processes are lacking in the hydrological literat

In this study university teachers? personal theories of their pedagogical practice in basic courses in undergraduate education are described and analyzed. According to for example Polanyi (1958) and Bourdieu (1990) university teachers have developed a personal practical theory as participators in an academic social context, first as students then as teachers. This can be seen as their ?pedagogy? a

Higher education has become a mega-topic in both political and scientific debate. Developments in systems of higher education and changes in the governance of such systems have been discussed in the literature. Such changes are brought about by collective actors within institutional settings. The present volume considers the policies of higher education supported by Social Democratic governments i

The purpose of this study was to systematically examine the social, cultural and psychological situation of a group of women with drug addiction, and to gain an understanding of it. Different theoretical perspectives were utilized in efforts to understand and explain why some young women start using drugs. The attempt was made to integrate a social psychological perspective with a perspective base

This study shows that the mechanisms behind knowledge accumulation and the sources of productivity growth differ from industry to industry depending on what is produced and what technology is used. Although it is apparent to most researchers in the field that the only way to explain long-run growth in output per capita is through technological progress and accumulation of knowledge that counteract

Wind erosion is a serious threat to soil resources as it causes depletion of the fine fractions that may result in a less fertile soil. Wind erosion encompasses several processes of which many are related to climate variables. To date, there is little work performed on how wind erosion relates to climate and climate change. In this thesis, atmospheric circulation and wind erosion were analysed to
