Planetesimal and Protoplanet Dynamics in a Turbulent Protoplanetary Disk: Ideal Unstratified Disks

The dynamics of planetesimals and planetary cores may be strongly influenced by density perturbations driven by magneto-rotational turbulence in their natal protoplanetary gas disks. Using the local shearing box approximation, we perform numerical simulations of planetesimals moving as massless particles in a turbulent, magnetized, unstratified gas disk. Our fiducial disk model shows turbulent acc

Infection biology of the plant pathogenic fungus Bipolaris sorokiniana

Bipolaris sorokiniana is a fungal pathogen causing severe disease mainly in wheat and barley worldwide. In this thesis two aspects of the infection process were investigated: the adhesion mechanism of the fungus and the role of the non-host specific phytotoxin prehelminthosporol (PHL) in the disease. Adhesion of B. sorokiniana to artificial solid surfaces occurred in two stages: the first by conid

Complementarity in language : toward a general understanding

Ever since its first conception in 1907 by Bergson, "complementarity" has come to represent extremely wholistic situations, for which fragmentability into parts turn out unsuccessful. In 1927, Bohr used the term complementarity within quantum mechanics, with profound consequences, for a principally unsuccessful fragmentability into independent observability and definability concepts. The paper ob

Pompeii revived : Scanning Mission - insula V 1

The Swedish Pompeii Project started in 2000 as a fieldwork initiated from the Swedish Institute in Rome. The aim was to record and analyze a full Pompeian city-block, Insula V 1. This paper presents the initial results of one of the actions in the context of this project. In October 2011, two houses were acquired using 3D scanning and 3d-from-photos techniques, and the data was processed to obtain

Tjetjenien i historiens grepp

The article traces the roots and developments of the Chechnyan conflict in factual history as well as in the warriors' uses of this history.

Evaluating the practical use of different measurement scales in requirements prioritisation

The importance of prioritising requirements is widely recognised. A number of different techniques for prioritising requirements have been proposed, some based on an ordinal scale, others on a ratio scale. Some measurement scales provide more information than others, i.e. the ratio scale is richer than the ordinal scale. This paper aims to investigate the differences between the scales used in pri
