The EU governance of food safety and GM food and feed has gone through significant changes since the BSE crisis and food scares during the 1990s. This work focuses on one particular new feature; the role of stakeholders representing the food chain: biotech associations, farmer organizations, food and feed processors, consumer organizations and environmental NGOs. These stakeholders are not merely
In this paper we evaluate the use of parallel interleavers for user separation in coded IDMA systems. The parallel interleavers have previously been evaluated for uncoded systems, and we here present extended results for the coded case. The new results are important for real systems, as they will most likely use performance enhancing channel coding. The parallel interleavers are designed to remove
The aims of the studies in the thesis were; 1.to investigate incidence, risk factors in comparison to non lacunar stroke patients, initial course and long term prognosis in pure motor stroke (PMS) 2.to determine topography and most probable pathogenetic mechanism of lesions in sensorimotor stroke (SMS). 3.to study if diffusion weighted magnetic resonance tomography(DWI) contribute to a more precis
Politics are not only about interests and institutions but discourses as well. Discourses are (dominant) ideas, concepts and categorisations in a society that give meaning to reality and that shape the identities, interests and preferences of individuals and groups. The assumption of this chapter is that forest discourses are constitutive to global forest politics. Three forest-related types of di
In trying to understand any aspect of success and failure in information systems practice, concepts of organisational analysis become increasingly important. Many issues arise and must be dealt with when an information system is to be developed and implemented. In order to avoid information system failures information system analysts should adopt an approach, which exploits the intrinsic and conte
Popular Abstract in Swedish I avhandlingen redovisas undersökningar av näringsdynamiken hos fem olika lövträdsarter (ask, björk, bok, ek och lind) vilka jämförs med gran, som är ett mycket undersökt trädslag ur närings-synvinkel. Målsättningen med studierna var att klargöra de olika trädslagens näringstillstånd under likartade förhållanden, deras inverkan på och samspel med marken, samt deras näriThis thesis considers several important aspects of nutrient dynamics and allocation in adult stands of Swedish forest tree species (Quercus robur L., Tilia cordata Mill., Fraxinus excelsior L., Betula pendula Roth., Fagus sylvatica L. and Picea abies (L.) Karst) planted on the same soils. Differences between species in macro- (N, P, K, Ca, Mg, S), and micro- (B, Cu, Fe, Mn, Zn) nutrient levels in
This paper presents an energy relaxation-based approach for the modeling of single crystalline magnetic shape memor)) alloy response under general two-dimensional magnetomechanical loading. It relies on concepts of energy relaxation in the context of non-convex free energy landscapes whose wells define preferred states of straining and magnetization. The constrained theory of magnetoelasticity dev
Field study of evacuation upwards long stairs, ascending evacuation, in two different buildings, 48 meters and 109 meters high. Measuring walking speed along the stair slope and vertical speed. Presenting values for different percentiles of the studied population. The importance of not using the same value for walking speed for different stairs since the design of the stairs has a strong impact, a
In this paper we will investigate the different algebraic varieties and ideals that can be generated from multiple view geometry with uncalibrated cameras. The natural descriptor, Vn, is the image of p3 in P2×p2×...×p2 under n different projections. However, we will show that Vn is not a variety. Another descriptor, the variety Vb, is generated by all bilinear forms between pairs of views and cons
