From the existing full set of international policy instruments on forests, eight core components are identified and submitted to two differing assessments. The first (consistency assessment) uses a policy design approach to match the core components with their goals, policy tools, target group preferences and justifications for the choice of goals and policy tools. The second (compatibility assess

This thesis consists of theoretical studies of the evolutionary consequences of environmental change in ecological communities. Paper I and II are concerned with the origin of diversity, i.e. how a single lineage can split into two, under the influence of selection induced by competitive interactions (evolutionary branching). In paper I we find that environmental fluctuations may affect the likeli

Experiments relying on tomographic reconstruction of soot emission and absorption offer relatively simple and inexpensive ways to image both soot concentration and temperature in axisymmetric flames. Because the tomography problem is mathematically ill-posed, however, special measures have to be taken to ensure an accurate solution. This paper describes the application of one such measure, Tikhono

Popular Abstract in Swedish I över 40 år har det varit möjligt att operera förslitning (artros) av höftleden med en konstgjord led. De allra flesta av de cirka 12 000 patienter, som opereras i Sverige varje år med så kallad höftplastik, får en ny höftkula av metall och en ny ledpanna av plast. De nya leddelarna förankras oftast i lårbenet (kulan) respektive bäckenbenet (pannan) med bencement, ett 144 consecutive hip revisions performed with morselized allograft bone and cement were followed up to 5 years after surgery. In 49 hips patient outcome was evaluated with the Nottingham Health Profile (NHP) questionnaire and Charnley hip scores in 47 hips prosthetic fixation was evaluated with radiostereometry (RSA)and in all 144 hips risks and complications were recorded using a prspective protoc

Popular Abstract in Swedish Häri avhandlas tesen att bättre insikt i kemisk jordförorening med tjärämnen kan erhållas genom två analytiska begrepp: tillgänglighet och kemisk aktivitet. Tillgänglighet syftar på andelen av den totala mängden PAH som är tillgänglig för processer vilka sker utanför jordpartiklarna. Det andra begreppet, kemisk aktivitet, är termodynamiskt. Den kemiska aktiviteten är häThis thesis proposes the use of two concepts: accessibility and chemical activity. Accessibility describes the mass quantity of PAHs that is or can become available within a given time span and under given conditions. Chemical activity quantifies the energetic state of the PAHs that determines the potential for spontaneous physicochemical processes, such as diffusion and partitioning. Chemical act

This is a chapter I wrote for a book, International Relations: A Beginner's Guide, edited by Stephen McGlinchey and forthcoming with E-International Relations Publishing in January 2017. It is my attempt to describe the origin of the state, and the European interstate system, as they came to develop from the Middle Ages onwards, and also to say something about how the European system spread to the

This thesis examines the scholarly study of Sir Thomas Malory’s Le Morte Darthur, especially the way in which the field has been shaped by the discovery of the Winchester MS in 1934. Owing to the complex relationship between the manuscript and the printed edition of 1485, both contradictory and co-dependent, Le Morte seems to invite a number of narratives regarding its origins and originality whil

The paper aims to explore to what degree different types of terms in engineering information (Ei) thesaurus and classification scheme influence automated subject classification performance. Preferred terms, their synonyms, broader, narrower, related terms, and captions are examined in combination with a stemmer and a stop-word list. The algorithm comprises string-to-string matching between words i

The developments and activities among the attendees to a Naqshbandi-Haqqani Sufi priory in north London in recent years have come to raise a number of issues regarding Sufism in Western Europe. The relationship between shaykh and murid, "disciple", has been developed into a complex interaction where ongoing negotiations concerning the content and form of the tariqa’s activities continuously take p
