Piledal and Svarte. A Comparison Between Two Late Bronze Age Cemeteries in Scania

Svarte and Piledal are typical Scanian Late Bronze Age cremation cemeteries.The Piledal cemetery has the quality of an enclosed entity used by a limited group of people. Svarte, on the other hand, is a more diffuse conglomeration of burials spread over a wider area. The article also contains a discussion of the impact of excavation methods and find circumstances on archaeological interpretation.

Epidural techniques - can we improve outcome?

In epidural studies it has been hard to find evidence supporting the outcome benefits of epidural treatment. A lot of epidurals have a high incidence of postoperative malfunctions. Several technical factors can be behind this. By knowing the relevant anatomy, the epidural insertion can be more optimal. Using saline instead of air as loss of resistance medium, a better working epidural with less mo

Minne, jag, 1800. Litterär självframställning hos Atterbom, Geijer, Widerberg och Heidenstam

Both the idea of the self and the idea of memory went through significant changes in the 18th and 19th centuries – developments that in important ways were driven by, and showcased in, the different forms of autobiographical expression popular during this period. With the aim of studying the Swedish context in this regard, the thesis describes a number of typical situations and thematic structures

Second-harmonic generation in optically trapped nonlinear particles with pulsed lasers

Pulsed lasers are used for simultaneous single-beam three-dimensional optical trapping of and second-harmonic generation in 50--100-nm nonlinear particles. The emission power of the frequency-doubled light, the trapping stability, and the particle degradation are investigated for KTP and LiNbO3 particles trapped by 25-kHz-repetition-rate Q-switched Nd:YAG and 76-MHz mode-locked Ti:sapphire l a s e

Electronic structure of nanometer-scale semiconductor wires

We report a theoretical study of the electronic structure and optical properties of GaAs nanowires grown in the [111] direction with a hexagonal cross section, based on a tight-binding approach. It is shown that in the nanowires the degeneracy of the light-hole and heavy-hole bands at the Γ-point seen in the bulk material is lifted, and the light-hole state is located above the heavy-hole state, i
