Popular Abstract in English Like earth is home for us, our gastrointestinal (GI) tract is home for microbes. All the bacteria that are living there are called “microbiota” and the total DNA they contain is called “microbiome”. The GI microbiota outnumbers human cells by factor of ten and the microbiome is at least 100 times larger than our human genome. A wide range of metabolic activities are perAbstract: Balanced microbiota of the gastrointestinal (GI) tract is important for maintaining health of the host. Altered gut microbiota have been found to be associated with various life-style induced and other intestinal inflammatory diseases. Gut microbiota is viewed as a metabolic organ and considered as new target for therapies. This thesis describes the work on exploring the microbiota of th

We present the growth of homogeneous InAs1-xPx nanowires as well as InAs1-xPx heterostructure segments in InAs nanowires with P concentrations varying from 22% to 100%. The incorporation of P has been studied as a function of TBP/TBAs ratio, temperature, and diameter of the wires. The crystal structure of the InAs as well as the InAs1-xPx segments were found to be wurtzite as determined from high-

In the developed countries the public expect society to be prepared for, and step in, if something out of the ordinary happens. This public pressure appears to have increased the demand for crisis preparedness planning. In crisis management the local authority serves as the first line of defence and will more or less always be involved in responding to crises. It is therefore important to study ho

Popular Abstract in German Einführung in die Astrometrie Ziele Astrometrie ist das Forschungsfeld der Astronomie, das sich mit der Vermessung der Positionen von Sternen und anderen Himmelskörpern beschäftigt. Das klingt zunächst vielleicht trivial, aber die unglaublich großen Entfernungen machen astrometrische Messungen äußerst schwierig. Eins der Ziele ist es, eine dreidimensionale Karte der SteAstrometry aims at producing a three-dimensional map of positions and motions of stars and other celestial bodies in a consistent coordinate system covering the whole sky. This is best done from space, which provides a way of scanning the entire sky by a single instrument in a thermally stable environment. Space astrometry was pioneered by the Hipparcos satellite (1989–1993), and the successor mis

The output power of a free-electron laser (FEL) can be greatly enhanced by tapering the undulator line. In this work, a sensitivity study of a tapered FEL is presented. The study is conducted using the numerical simulation code GENESIS and a taper optimization method. Starting from a possible case for the future X-ray FEL at the MAX IV Laboratory in Lund, Sweden, a number of parameters are varied

Exploring emotional relationships between user and product is an important issue to adress in the design of t non-discriminating everyday products. Universal design is one approach among several, which the industrial designer can use when designing on the basis of on a non-discriminating philosophy. One way to achieve an integration of the user product relationship into the concept of universal de

Surfaces subjected to rolling and sliding contacts may suffer from contact fatigue. The cam and roller follower mechanism is a typical rolling and sliding contact. This thesis deals with the running in aspects to avoid high stress variation that leads to fatigue wear and the aspect of what happens to indentation damages that occurs on the surface if there are any particles in the lubricant. The pa
