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
Diffuse reflectance spectroscopy (DRS) with a fiber-optic contact probe is a cost-effective, rapid, and non-invasive optical method used to extract diagnosis information of tissue. By combining commercially available VIS- and NIR-spectrometers with various fiber-optic contact-probes, we have access to the full wavelength range from around 400 to 1600 nm. Using this flexible and portable spectrosco
'Amsterdam is standing on Norway' - this was a popular saying in the Dutch Republic of the seventeenth century. There was more than one inflection to the phrase. Amsterdam was, in the first instance, built atop a subterranean forest of Norwegian origin. But southern Norway was also a vital resource zone, subordinated to Amsterdam-based capital. This paper follows the movement of strategic commodit
Measurement of intracardiac kinetic energy (KE) provides new insights into cardiac hemodynamics and may improve assessment and understanding of heart failure. We therefore aimed to investigate left ventricular (LV) KE time curves in patients with heart failure and in controls.
