Three different biological extremes of irradiation of living organisms, both human and animal, have been investigated and are presented in this thesis. Central to the thesis is the concept of bystander effects of ionizing radiation, i.e. biological responses in a cell that are not caused by that cell receiving a direct hit by ionizing radiation but by the fact that a neighbouring cell has been hit
This dissertation aims to investigate the social situation at school for students that have migrated to Sweden during their last four years at compulsory school or during upper secondary school. The study investigates the social interaction between students with a special focus on the possibilities and hindrances for inclusion of the newcomer immigrant students in different groupings at school, an
In this presentation I discuss modern psychiatry, esp. neuropsychiatry, from the perspectives of philosophy and sociology of science. It is argued that there exist a number of tensions and ‘incommensurabilities’ in the field that are hard to overcome, thus giving rise to controversies. I separate four types of tensions, belonging to different ‘boxes.’ The first is called cognitive/internal, compri
In this paper, we approach a multiobjective Hp prob lem with several Hp constraints from the Banach duality point of view. The problem is reduced to an abstract norm minimization problem, and the dual problem is derived using the classical Banach re sult. It completes the primaldual pair which can be used to solve the problem numerically by nite dimensional approximations. While the approxima
Sum rules for the antenna input impedance and admittance are introduced. These identities relate the radiation resistance and conductance integrated over all frequencies with the low-frequency capacitance and inductance. They are valid for lossless antennas and particularly useful for small antennas that utilise their first resonance. Numerical results for various antennas are used to illustrate t
Objectives. The aim of the study was to investigate older persons' experiences of using mobility devices. Methods. In this qualitative study, focus group interviews were carried out with participants living in two municipalities in the south of Sweden. Occupational therapists and physiotherapists identified interested participants, 65 years or older. A total of 22 persons participated once in the
In this paper it is shown hour corresponding conics in two images can be used to estimate the epipolar geometry in terms of the fundamental/essential matrix. The corresponding conics can, be images of either planar celtics or silhouettes of quadrics. It is shown that one conic correspondence gives two independent constraints on the fundamental matrix and a method to estimate the fundamental matrix
