How unified is the European Union?

The European project has come a long way in establishing peace, creating a common market, and expanding its borders. At the same time, diminishing popular legitimacy has spurred talk about a European Union in crisis. How far has the EU really come in fulfilling its grand visions? Is the project barely half-way? Or could we say with some confidence that European integration is solidified and will c

Waterfowl herbivory on submerged macrophytes in eutrophic lakes

Popular Abstract in Swedish Sjöfåglar påverkar undervattensväxter Liksom korna på betesmarken betar och påverkar växter på olika sätt, kan växtätande sjöfåglar påverka växter i sjöar. Svanar, sothönor och änder äter ofta undervattensväxter och jag har undersökt hur växterna påverka's av detta. Fågelsjöar är ofta näringsrika grunda sjöar, där växtproduktionen dominera's av undervattensväxter. OliSubmerged macrophytes are thought to stabilize clear-water states of shallow lakes. The aim of this thesis was to elucidate how waterfowl herbivory can affect abundance, distribution and species composition of submerged macrophytes in eutrophic lakes. I found that in a lake with sparse vegetation, which was in a colonization phase, small plants were uprooted and large plants were heavily grazed up

Computer Aided Planning of Production and Working Environment

Success of design projects depends on their quality from a technical and economic point of view and on the quality of their implementation and use. This paper discusses a computer aided planning (CAP) technique and its applicability and quality in both these respects. One version of the CAP-technique is developed for planning of industrial working environments and another version for planning of r

A Multiple-View Batch Plant Information Model

This paper presents a combined control and information model. Existing concepts from the information system area are modified to suit batch applications. The model has been applied to a simulated scenario consisting of a multi-purpose multi-path batch cell. The goal of the information model is to establish a framework for information systems that supports integrated batch plant operation.

Genetic variation, polyploidy and hybridization in Scandinavian Anthericum ramosum and A. liliago (Anthericaceae)

In this thesis, I investigate the differences in breeding system, levels of genetic variation and hierarchical structure of genetic diversity between Anthericum ramosum and A. liliago. The two species differ in ploidy level and flowering time, but have similar habitat preferences, reproductive biology and geographic distributions in Scandinavia. I also assess the potential for hybridization and ge
