We designed and investigated four-arm nanostructures, composed of two perpendicularly crossed stripes, fabricated from ferromagnetic (Ga,Mn)As layer by means of electron-beam lithography patterning and chemical etching. The nanostructures exhibit a bistable resistance behavior resulting from two configurations of magnetic domain walls in the central part of the structures. We demonstrate a possibi
Reproductive investment decisions form an integral part of life-history biology. Selection frequently favours plasticity in investment that can generate maternal effects on offspring development. For example, if females differentially allocate resources based on mate attractiveness or quality, this can create a non-genetic link between mate attractiveness and offspring fitness with potential conse
Objective: Different hypothalamic-pituitary-adrenal (HPA) axis function tests are used for diagnosing disease and evaluating suppressive effects of corticosteroid treatment. Our objectives were to evaluate sensitivity and precision of different HPA axis tests to be able to select one that combines good performance with good practicability, suitable for investigation of new corticosteroids in clini
Genetic variation plays ail important role in osteoporosis and a prime candidate gene is Collagen alpha2(I) (COL1A2). A coding polymorphism (rs42524) in COL1A2 has previously been associated with intracranial aneurysms. Here the effects of this polymorphism have been Studied in relation to bone mineral density (BMD) and prevalences of stroke and myocardial infarction (MI). rs42524 was genotyped in
In endeavouring to explain the empirical puzzle that the sunk costs of exporting are important, but that, at the same time, trade flows do not, on average, survive for very long, this paper explores the concepts of core and peripheral markets. First, it illustrates that if the importance of sunk costs as well as the expected future returns from exporting are different, depending on whether the exp
Anisotropic interactions in colloidal suspensions have recently emerged as a route for the design of new soft materials. Nonisotropic particles can form nematic, smectic, hexatic, and columnar liquid crystals. Although the formation of these phases is well rationalized when excluded volume is solely at play, the role of electrostatic interactions still remains unclear and even less so when particl
Methylamine adsorption on the ordered Ni3Al(111) and NiAl(110) surfaces has been investigated by high resolution photoelectron spectroscopy and density functional theory calculations. Methylamine adsorbs molecularly at both surfaces at low temperature (90 K). The experiments show that methylamine interacts with the surface aluminium atoms on both surfaces, resulting in a positive binding energy sh
Abstract in French Cette étude vise à mettre en lumière l’acquisition de la liaison préverbale en tant qu’accord sujet-verbe en nombre en français langue étrangère (FLE). Le but principal de l’étude est d’examiner le développement de ce trait morpho-phonologique et d’évaluer l’impact de la fréquence du verbe pour l’emploi de la liaison préverbale en FLE. Nous présentons une étude transversale où 4
Occupational therapists working with clients in productive occupations explicitly or implicitly assess their clients' occupational engagement.
In 2000, the International Union of Geological Sciences (IUGS) ratified the decision from the International Working Group on the Cambrian–Ordovician Boundary (COBWG) to place the Global boundary Stratotype Section and Point (GSSP) for the base of the Ordovician System in the Green Point section, Newfoundland, Canada, at a point coinciding with the first appearance of the conodont Iapetognathus flu
Despite the ever-growing literature on various aspects of the Kurdish question in Turkey, there are practically no normative discussions of Kurdish demands for the public recognition of their identities. This is all the more startling given the ascendancy of philosophical accounts in the literature on minority rights. This article will try to redress the balance by proposing a normative framework
The Bologna process is a voluntary joint venture among 46 European countries, which has as its objective the creation of a European Higher Education Area (EHEA) by 2010. The EHEA will cover all of Europe including European Union newcomers Armenia, Azerbaijan, Georgia, Moldova, and Ukraine. Its aim is to allow for degrees and qualifications awarded in one country to be understood and recognized in
Environmental conditions, dispersal lags, and interactions among species are major factors structuring communities through time and across space. Ecologists have emphasized the importance of biotic interactions in determining local patterns of species association. In contrast, abiotic limits, dispersal limitation, and historical factors have commonly been invoked to explain community structure pat

The normal distribution of von Willebrand factor (VWF) levels is wide. Low levels are associated with bleeding symptoms and von Willebrand disease (VWD). We have recently described a high prevalence of bleeding symptoms in a whole age group of young females (n = 1,019) from Malmo, Sweden. It was the objective of the present study to evaluate the distribution of VWF levels in young females with or
Popular Abstract in Swedish På lång sikt drivs ekonomisk tillväxt av teknisk utveckling. Det är genom att kunna producera mer och bättre produkter givet samma insatsfaktorer som bruttonationalprodukten (BNP) växer i det långa loppet. Men vad är det då som genererar teknisk utveckling? Jo, satsningar på forskning och utveckling (FoU). Dock är det så att resultaten från FoU – ny kunskap och ny tekniThis thesis deals with the organization of R&D from a micro perspective in order to get a better idea of how to generate economic growth in the long run. What kind of R&D policies should be promoted? This thesis contributes to the existing literature by investigating other data sets than before, by using more modern econometric techniques and by extending the investigated variables. Chapt
