Popular Abstract in English In this thesis we investigate the manipulation of the magnetic properties of molecular magnets by means of external electric fields. This manipulation is mediated by either the spin-electric coupling or the magnetic anisotropy of the molecular magnet. In order to understand what this means, let us first explain some basic concepts about magnetism. We will start explainiThis dissertation investigates theoretically electric control of the magnetic properties of molecular magnets. Two classes of magnetic molecules are considered. The first class consists of molecules that are spin frustrated. As a consequence of the frustration, the ground-state manifold of these molecules is characterized by states of different spin chirality, which can be coupled by an external e

Cancer is a disease that will affect most of us during a lifetime. Although the survival of cancer patients has incresed due to better treatment and earlier diagnosis, the prevalance of the disease is still increasing. This increase in the number of cancer cases diagnosed will impose a challenge to the cancer care and higher costs for socitey. Personalized medicine aims at reducing these costs whi

This thesis is about various views on the structure of wages. Special attention is given to the theory of multi-dimensional work, earlier discussed by K.J. Lancaster and J. Tinbergen.

There are many good reasons for turning co-located projects distributed, likewise there are many good reasons for turning traditional projects agile. In both cases there are many obstacles to overcome and pitfalls to avoid and the combination of agile and distributed does not make this situation any better. In general Configuration Management works as the infrastructure of any software project and

A great deal of attention is currently being paid in urban sociology to the relationship between place and identity. The background to the growing interest in the identity development of individuals can be found in the radical changes the city is presently undergoing. These changes have often been described in terms of the dissolving city, a concept that not only refers to the continuing physical/

In this paper, physical limitations on the partial gain G and relative bandwidth B are derived for antennas of arbitrary shape based on holomorphic properties of the forward scattering dyadic. The limitation on the performance of G and B is shown to be bounded from above by the long wavelength response of the antenna in terms of the electric and magnetic polarizability dyadics. The special case of

These are the proceedings of the workshop on ``Effective Field Theories of QCD'' held at the Physikzentrum Bad Honnef of the Deutsche Physikalische Gesellschaft, Bad Honnef, Germany from November 26 to 30, 2001. The workshop concentrated on Chiral Perturbation Theory in its various settings, its relations with lattice QCD and dispersion theory and the use of effective field theories in systems wit
