To fulfill increasing requirements within the manufacturing sector, highly flexible and adaptable automation systems are needed. It is desirable to have one integrated approach that stretches from the process planning phase, through the implementation phase and all the way to the phase for execution of the process control logics. One promising approach is to use the concepts of service-oriented ar

The topic of this thesis is the electro-mechanical oscillations which to some extent always are present in a power system. The demand of electric power is ever increasing. At the same time, the tolerance of disruptions in the power supply is decreasing. The deregulated market together with distributed generation have then pushed the system to operate during circumstances for which it was not desig

In this thesis aspects of peripheral B lymphocyte differentiation were studied. Through in vitro experiments, B lymphocyte activation was assessed. B lymphocytes express immunoglobulin (Ig) specific for a certain antigen on the cell surface, and when surface Ig is crosslinked by an antigen, the cell is activated. Antigens giving rise to a T cell dependent immune response are internalized by the B

This dissertation deals with discrimination of part-time and fixed-term workers. The EU directives on part-time and fixed-term work, as well as Swedish law in the same area, are the starting point of the analysis. The aim is to offer a reading of discrimination law as an instrument for freedom from subordination. Inspiration is found in critical legal positivism’s idea of the autonomous individual

This thesis consists of four self-contained, yet related articles which all contribute mainly to the corporate governance literature. Very broadly, the first two papers are on family firms and large shareholders in Sweden while the second two are on Enterprise Risk Management (ERM) practices in Nordic countries. The contribution of Paper 1 is that I for the first time take into account the two dim

För drygt tio år sedan startades det s.k. mellanstadieprojektet – numera ”femteklassprojektet". Det hela går ut på att teknologer besöker mellanstadieklasser, i första hand femteklasser. Besöket inleds med ett antal spännande demonstrationsförsök ("teknik-, kemi- och fysikshow"). Teknologerna berättar om sig själva, om vad man gör på den tekniska högskolan och vad LTH är för någonting. Ett viktigt

The intestinal flora and the bacteria found in the extraintestinal sites were studied in liver injury rats, with or without Lactobacillus plantarum 299v pre-treatment. The dominating intestinal flora and translocating bacteria were typed by RAPD and identified by 16S rDNA sequencing. It was proved that bacterial strains from the intestine could pass through the intestinal barrier to the extraintes

What distinguishes the "new perspective on Paul" — and what lies beyond it? What are scholars saying about Paul and the Roman Empire or about the intersection between feminist and postcolonial interpretation of Paul? Magnus Zetterholm provides a clear and reliable guide to these and other lively issues in the contemporary study of Paul, surveying the history of the principal perspectives on Paul's

The main topic of this Thesis is the x-ray spectroscopic studies of free nano-clusters with size more than 10^3 atoms. The photoelectron spectroscopy experiments on rare gas and metal clusters were performed at beamline I411 at MAX-lab National Swedish synchrotron radiation facility. Free rare-gas clusters are simplest objects in cluster research. However their electronic structure springs a lot
