Characterization of low-dimensional semiconductor structures is a challenging task. The thesis is based on experiments, using cathodoluminescence (CL) as a tool for characterization. The high spatial resolution and the possibility of spectroscopy of small structures make CL one of the most powerful techniques for these types of investigations. QDs were fabricated of InP on GaInP and InAs on GaAs b

The surrounding world, filled with objects, is the foundation of our actions, thoughts and emotions. Equally, we affect things and objects in our turn, through the interpretation and the significance we give them. In regard to old age, certain objects, as well as places, may become problematic. Some things lose their importance and fall out of use while others appear and become integrated in every

Mouth alcohol (MA) is a potential source of error in alcohol breath-testing. Although utilized commercially for MA-detection, the exhalation profile of breath samples containing MA has not been systematically studied before. To characterize the exhalation profile of MA, volumetric expirograms of single-exhalations containing MA were examined. In addition, to explain reports of unusual slow elimina

While the conceptual history of the sign, as recounted by John Deely in Four ages of understanding, is immensely enlightening, history is never enough. If, before Augustine, it had occurred to no one that such diverse phenomena as are covered by this term had something in common, and if, in the time of Aquinas, Fonseca, and Poinsot, different usages of the term were in competition, the reason is n

Apolipoprotein M (apoM), a 25 kDa plasma protein, is found in all major lipoprotein classes, although the majority is found in high density lipoproteins (HDL). ApoM has been suggested to be involved in the formation of and adding to the antiatherogenic functions of HDL, but its function is still not completely known. ApoM has been suggested to be a lipokalin. By studies in vitro using recombinant

The combined data from three fusion-evaporation reaction experiments have been utilized to investigate the semi-magic nucleus Ni-58(28)30. To detect gamma rays in coincidence with evaporated particles, the Ge-detector array Gammasphere was used in conjunction with the charged-particle detectors Microball and LuWuSiA (the Lund Washington University Silicon Array), and a neutron detector array. The

The morphology and molecular mechanisms of animal photoreceptor cells and eyes reveal a complex pattern of duplications and co-option of genetic modules, leading to a number of different light-sensitive systems that share many components, in which clear-cut homologies are rare. On the basis of molecular and morphological findings, I discuss the functional requirements for vision and how these have
