In the present thesis, I investigated the inter- and intraspecific variation in the Silene vulgaris/uniflora species-complex (the bladder campions). I have focused on the effects of past and present hybridization both on a large scale ? over the whole of Europe ? and on a local scale. Silene vulgaris and S. uniflora are perennial herbs and they are interfertile. The results from my studies sugges
Food production and consumption are key drivers of environmental pressures and are essential factors in the promotion and maintenance of health. Production of food occupies more than one third of global land areas and is estimated to be responsible for some 30% of global greenhouse gas emissions. At the same time, we live in a world where nearly one billion people go hungry and even more people su
The evaluation of skeletal muscle strength is an important part of the physiotherapist’s clinical examination in order to plan and execute appropriate interventions. This requires the objective assessment of muscle strength and the determination of the underlying factors of muscle weakness. One factor that can contribute to muscle weakness is the inability of the central nervous system to voluntar
Cellulose and starch are non-toxic, biodegradable and modifiable polymers. These properties have made them increasingly important in industrial products e. g. in pharmaceutical applications and in technical dispersions. By chemical modification of these polymers the physical and chemical properties of the polymer can be adjusted to suit a certain area of application. The characteristics of modifie
This thesis is founded on the premise that traditional discourses of travel and mobility are inherently masculinist, that is, travel is seen as a masculinity rite-of passage for the Euro-American male, shaping his subjectivity through the othering and marginalization of women. Taking Jack Kerouac’s On the Road (1957), the epitome of masculinist travel literature, as a starting point for an examina
Since the end of the Cold War, international politics and international law have not only become increasingly intertwined, but their mutual implications have also become increasingly recognized by scholars. Yet research explicitly addressing the question of how political factors affect the emergence of legal rules is still limited. This doctoral dissertation aims to take a step in the direction of
Many species associated with old trees are threatened, as this habitat has decreased severely in Europe during the last 200 years. In old oaks, hollows with wood mould often form in the trunks and these harbour a specialized fauna mainly consisting of beetles, flies and pseudoscorpions. This thesis contains the first quantitative examination of the habitat requirements and population ecology of sp
Evolutionary theory predicts a disadvantage to sexual reproduction. This manifests itself either by the higher growth rate of asexual females in a dioecious species, or by the higher transmission rate of a gene conferring asexual female function to its carriers in a hermaphrodite species. The disadvantage to sexual reproduction may be as high as two-fold provided all else is equal. This phenomenon
In children, it is often desirable to minimize allogenic blood transfusion, and this thesis explores the physiology of an alternative method of managing perioperative blood loss: hemodilution with Ringer´s dextran. Methods Clinical studies: Arterial pressure, superior caval venous oxygen saturation (ScvO2) and blood lactate concentration (L) were studied during bone marrow harvesting (BMH) on 23
This Ph.D. thesis is about how the design of measurement systems may influence-or even drive-the integration of firms in supply chains, and is based on research presented in my licentiate thesisR. The research aims at providing a conceptual framework for designing measurement systems in supply chains, and at supporting firms in their quest for ways of developing closer relationships with suppliers
This thesis focuses on contemporary organ improvisation in Western European musical culture. The aim of the study is to explore organists’ descriptions, constructions and definitions of improvisation in words and music, with an interest in the interaction between receptivity, creativity and change. As a research object, the art of organ improvisation is defined as a source for exploring learning a
An inductively coupled plasma mass spectrometry (ICP-MS) method for the determination of lead in blood plasma has been developed. The detection limit was below 0.1 microgram/liter, and the precision 5%. There was no significant difference between levels in plasma and serum. Studies of individuals with varying lead exposure showed that in the general population the plasma concentrations were less t
In the present thesis benign breast lesions of various histologies, i.e., fibrocystic lesions from women with and without a known hereditary predisposition to breast cancer, fibroadenomas, phyllodes tumors, and papillomas were cytogenetically investigated with the aim to characterize the chromosomal patterns, and to relate the findings with those in breast carcinomas. No lesion-specific aberration
Endometrial cancer is the most common gynecological cancer diagnosed in western countries. Complex atypical hyperplasia (CAH) reflects a state of hyperestrinism and its role as a precursor lesion of this cancer is established. Endometrial cancers arising in association with CAH are reported in women of younger age, with early stage disease, favorable histological types, higher progesterone recepto
Sample clean-up methodologies based on supercritical fluid extraction (SFE) have been developed for determination of fat-soluble vitamins in foods. This thesis focuses on method development, stressing important issues concerning sample pre-treatment, extraction conditions and collection parameters. It was demonstrated that by using SFE followed by saponification and determination using RP-HPLC wit
In the present work, I study various aspects of Martin Buber's model of how a human being can communicate, in a meaningful way, his or her religious experiences to and with another human being. My method has aspects of both conceptual analysis and phenomenologial description. I focus on the individual partners, their mutual relationships and the religious message. Buber's model is based on the con
Diffusion in bone is needed for bone remodeling and bone healing. Understanding the phenomenon is often important for comprehension bone diseases. Mathematical modeling of the diffusion processes is a required prerequisite in the study of this important physical process in living bone tissue. A proper model is crucial in order to obtain realistic results. An easily accessible method to measure the
Visual conditions are changing in several different ways. Some lakes are getting turbid due to eutrophication or erosion while others are getting browner due to brownification. These two types of visual degradation results in completely different optical properties of lakes. Turbid water scatter light which degrades image quality severely while brown coloured humic water mainly absorb light making
A solar magnetic field is continuously being created in the solar interior. As the field evolves outward through the solar atmosphere and into the enveloping heliosphere, it causes effects on a wide range of temporal and spatial scales. By studying and measuring these magnetic effects we gain extensive knowledge about solar magnetism and it also allows us to model and predict how solar activity is
This dissertation argues for an interpretation of liberty in terms of non-domination rather than non-interference, that non-domination can work as an independent criterion of political legitimacy, and that non-domination includes an approximation of equality in socioeconomic goods. In the first part, four theories of liberty and power – those of Kant, Locke, J. S. Mill and H. Taylor, and Wollstone
