Abstract Hot springs in Iceland can serve as sources of thermophilic, xylanolytic bacteria secreting very thermostable xylanolytic enzymes. The aerobic, thermophilic bacteria Rhodothermus marinus secretes multiple xylanases and xylosidases. One of the xylanases was purified to electrophoretic homogeneity and was characterized. The N-terminal sequence showed no homology with other xylanases. The p
The causes of autoimmune diseases are largely unknown today, but there is evidence supporting a substantial complex genetic influence on many of these diseases as well as environmental factors and chance. In this thesis I have tried to get one step closer to the genetic causes of two autoimmune diseases through their induced counterparts in mice, namely rheumatoid arthritis (RA) and multiple scler
Heart disease results from the loss of cardiomyocytes following myocardial damage and is a leading cause of death worldwide. Stimulating the endogenous regeneration of cardiomyocytes or isolating them from in vitro culture is an attractive therapeutic strategy. In paper I, the focus is on the cellular growth patterns of murine cardiomyocytes under steady-state conditions. The turnover of cardiomyo
Land degradation is commonly perceived to be severe in many parts of semi arid China. The transition towards market economy since the 1978 reforms, have set marginal dry lands under added pressure in the form of increased livestock numbers and expanding cultivation on erosive soils. To evaluate land degradation since the reforms, this study focuses on mapping and analysing the biological productio

Background: The aim of this study was to evaluate the test-retest reliability and the validity of the self-reported questionnaire Olerud-Molander Ankle Score (OMAS) in subjects after an ankle fracture. Methods: When evaluating the test-retest reliability of the OMAS, 42 subjects surgically treated due to an ankle fracture participated 12 months after injury. OMAS was completed by the patients on t
The overall aim of this study is to describe a number of different uses of the French "seul" and "seulement", and to account for the observed differences within a generative framework. After an introductory chapter, chapters two and three present a survey of earlier studies. The fourth chapter concerns an empirical study of authentic occurrences of "seul" and seulement", drawn from the press. The
The life cycle of electronic products is associated with significant environmental impacts. Compared to many other products, the production of electronics and in particular semiconductors is resource intensive and generates a number of highly toxic waste streams in manufacturing and post-consumer stages of product life cycle. Electronics manufacturing industry has been successful in reducing envir
This dissertation analyzes the work on universal morality by the Swiss theologian Hans Küng. According to Küng, a universal morality can be formed out of the world's religions that can reconcile ideological, cultural and religious differences. This morality can then form the basis for international policy and politics and guarantee that relations among states are peaceful. Küng's project focuses
Antibiotic resistance is now a large threat with worldwide agreement that we will fall into a post-antibiotic era unless there is suitable treatment alternatives discovered. In recent years, chronic wounds have become a major burden on society and treatment is complicated. Honey has been widely used as a topical treatment for wounds yet there is much discourse between studies examining its effect
Ritual creativity may seem like a contradiction in terms, yet the religious landscape in contemporary Euro-America is permeate with experimentation of ritual forms, different modalities of action, imagination and play as routes to authenticity. The present study examines different settings in Europe involved in such ritual creativity, which would commonly be classified as postmodern spirituality,
WHAT THIS STUDY ADDS Previous comparisons between open and endovascular repair of popliteal aneurysms have focused on asymptomatic patients, and have short follow up. This study is strengthened by the fact that it is contemporary, population based, without any selection bias, reporting on all kinds of presentations, and has approximately 90% 1 year follow up data. It shows that endovascular repair
There are various ways in which Enterprise Architecture (EA) is defined these days. One of the more common definitions is that EA is a dashboard that allows business architects and other stakeholders to govern an enterprise’s transformation process. This dashboard shows current operations as well as its future and desired state. In theory this might seem as a good tool for enterprise architects bu
