Abstract In this thesis I address some of the ethical issues that arise in relation to consumers and personalised dietary advice made on the basis of genetic information. By carrying out two empirical studies, I wanted to find out what Swedish consumers think about personalised nutrition, and how they reason regarding risks, possible value conflicts, and benefits that may arise from implementing t

A high-power laser facility has been established at the Lund Institute of Technology, Sweden, available to national groups and their international collaboration partners. The laboratory incorporates three major 10 Hz laser systems, that can be operated individually or synchronized in combined use. Each system represents extreme optical powers in a certain sense. The main system is a terawatt laser

The existence of traveling waves for the original Whitham equation is investigated. This equation combines a generic nonlinear quadratic term with the exact linear dispersion relation of surface water waves on finite depth. It is found that there exist small-amplitude periodic traveling waves with sub-critical speeds. As the period of these traveling waves tends to infinity, their velocities approac

This paper derives physical limitations on the interactions of antennas exciting TM or TE modes (but not both) and wireless propagation channels. The derivation is based on the spherical vector wave expansion of the electromagnetic field outside a sphere circumscribing the antennas. The result is an extension of the seminal work of Chu on the classical limitations on maximum antenna gain and radia

De största invandringsvågorna till Sverige har sammanfallit med de epoker då riket utvecklats allra mest. Historien ger oss inga rimliga skäl att betrakta immigration som ett problem – tvärtom kan dess betydelse för vårt välstånd knappast överskattas.

Gastric bypass (GBP) has been the most common surgical way to treat obesity and its comorbidities. Late abdominal pain may occur by gastro-jejunal ulcers, gallstones, internal herniation or, rarely, intussusception. In an area with more than 1000 GBPs performed yearly, three patients with primary small bowel volvulus causing abdominal pain and requiring emergency or semi-urgent surgery were identi

For evaluation of specific antenna arrangements in wireless communication systems we need physical channel models that take into account the directional domain. Here we propose a practical approach to wireless channel modeling in, particularly, mobile communication systems, by using an assumption that the channel can be divided into separate parts or regions that can be treated and modeled individ

I arbete och umgänge med människor med någon form av kognitivt funktionshinder har bilder och symboler använts länge. Syftet med denna rapport om digitala bilders betydelse för personer med kognitiva funktionshinder är att visa på att det finns en utbredd användning av digitala bilder inom skola, vård och omsorg, och att det finns mycket kunnande inom området. Jag hoppas också att rapporten ska tj

Laser spectroscopy of free atoms has been pursued for 25 years starting in the visible region and with a constant thrust towards shorter wavelengths. A review of generation schemes and atomic-physics experiments in the short-wavelength region is given. Processes in ions and inner shells occur on a very fast timescale setting special demands on the sources. Using picosecond laser technology efficie
