It is shown how tilt anisoplanatism in laser-supported multi-conjugatedadaptive optics (MCAO) systems can be a) predicted from a prioriknowledge, b) compensated using additional natural guide stars (NGS),and c) estimated in real time from control loop data to allow PSFretrieval. As a consequence of the problems associated with retrievingatmospheric tip and tilt from laser guide star (LGS) measurem

Från det vi föds är vi inställda på att lära. Vi iakttar människorna som omger oss och gör som de; vi lär oss tala, samspela, kommunicera. Vi lär genom att imitera. Drivkraften att lära genom efterbildning är något vi använder i retorikundervisningen; våra studenter utvecklar sina egna färdigheter i tal, skrift, läsning och lyssning genom att studera goda exempel och efterbilda dem. Principen kall

Fine particle emissions were measured at two commercial grate fired boilers operating on moist fuel residues. The aim of this study was to characterize fine particle emissions with a view to pinpoint parameters influencing the emissions. Additionally effectiveness of used flue gas cleaning techniques was assessed. The results show that large quantities of fine particles are emitted to the atmosphe

Competing Institutional Logics in Diaconal Work “Institutional logics” is a concept within the context of institutional theory. Institutions can be defined as patterns of activity rooted in material practices and symbolic systems. These institutional orders are all shaped by the history and each of them has a central logic that guides its organizing principles. The institutional logic provides

Summary – 200 words In education today, there is a paradigm shift with critical challenges for Universities to enhance innovation in teaching and learning. Knowledge and learning are critical issues for most companies and private and civil service organizations with today’s rapid changes in socio-economy and technology. The needs for competence development vary along a broad scale from short info

Chronic lymphocytic leukemia (CLL) is a clinically heterogeneous disease with no known single predisposing genetic factor shown in all cases. Recently, a single nucleotide polymorphism (SNP) T393C in the GNAS1 gene has been reported to have a clinical impact on CLL progression and overall survival. In order to further investigate the T393C SNP in CLL, we have genotyped 279 CLL cases and correlated

Laser-induced fluorescence is a technique for optical tissue characterisation. It has a real-time capability and as the excitation light and the fluorescence emission are transmitted through optical fibres the technique is compatible to various kinds of endoscopes for hollow organ investigation. The tissue fluorescence itself with the emission from the endogenous chromophores or enhanced with exog

A selective and sensitive method is presented for biogenic amines (BA) determination. The novelty consists in coupling a highly selective electrochemical biosensor to a weak acid cation-exchange column for online detection of amines. A bienzyme design, based on a recently isolated amine oxidase from grass pea and commercial horseradish peroxidase, was used for the biosensor construction. The enzym
