The effect of plant species diversity on productivity and competitive ability was studied in an experiment carried out simultaneously in five European countries: Czech Republic (CZ), the Netherlands (NL), Sweden (SE), Spain (SP), and United Kingdom (UK). The aim was to separate the 'chance' or 'sampling effect' (increasing the number of sown species increases the probability that a species able 't

I argue along the following lines: For Wollstonecraft, liberty is independence in two different spheres, one presupposing the other. On the one hand, liberty is independence in relation to others, in the sense of not being vulnerable to their whim or arbitrary will. Call this social, or political, liberty. For liberty understood in this way, infringements do not require individual instances of int

1 Plant species differ in their capacity to influence soil organic matter, soil nutrient availability and the composition of soil microbial communities. Their influences on soil properties result in net positive or negative feedback effects, which influence plant performance and plant community composition. 2 For two grassland systems, one on a sandy soil in the Netherlands and one on a chalk soi

This paper gives a brief summary of computational methods in heat transfer equipment, i.e., CFD (computational fluid dynamics) methods for thermal problems, and turbulence modeling for single phase applications in the design, research and development of heat exchangers. Some examples for real heat exchangers are shown to demonstrate how CFD methods can be used as R & D tools. Nevertheless, lim

We introduce and provide a new data-set of species-specific ecological indicator values (alternative ‘Ellenberg values’ for climatic variables, light, moisture, soil reaction/pH, salinity, nitrogen and phosphorus plus response to management and disturbance), physiological and reproductive traits (including symbionts, phenology, pol- linators, nectar production, seed properties), indices of relevanWe introduce and provide a new data-set of species-specific ecological indicator values (alternative ‘Ellenberg values’ for climatic variables, light, moisture, soil reaction/pH, salinity, nitrogen and phosphorus plus response to management and disturbance), physiological and reproductive traits (including symbionts, phenology, pol- linators, nectar production, seed properties), indices of relevan

Objectives: to characterize the clinical presentation of patients with acute thrombo-embolic occlusion of the superior mesenteric artery (SMA).Design: prospective study.Materials: twenty-four consecutive patients admitted to Blekinge County Hospital, Karlskrona, Sweden, with acute thrombo-embolic occlusion of the SMA, over a three-year period from April 1999 through March 2002.Methods: clinical da

Deliberate self-harm behavior (DSH) can have profound effects on a person’s quality of life, and challenges the health care system. Even though DSH has been associated with aggressive interpersonal behaviors, the knowledge on DSH in persons exhibiting such behaviors is scarce. This study aims to (1) specify the prevalence and character of DSH, (2) identify clinical, neurocognitive, psychosocial, a

Globalisation traps, balkanisation, class polarisation, the dominance of transnational companies and the subordination of transnational migrants are all part of the imaging broadcast over the global media, and they merge with experiences of fear and joy in the countdown to the next millennium. The globalisation of fragmentation consists in driving a class wedge through the ethnic groups themselves
