The influence of finite length gradient pulses on NMR diffusion experiments on liquids confined to diffuse between two parallel planes is investigated. It is experimentally verified that the pore size decreases when determined using finite gradient pulses if the results are analyzed within the short gradient pulse approximation. The results are analyzed using the matrix formulation. The observed m

Philosophers of science have often favoured reductive approaches to how-possibly explanation. This article identifies three varieties of how-possibly explanation and, in so doing, helps to show that this form of explanation is a rich and interesting phenomenon in its own right. The first variety approaches “How is it possible that X?” by showing that, despite appearances, X is not ruled out by wha

This paper deals with experiences from a successful previous pilot project under the Leonardo da Vinci programme implemented during the time period 2002-2006. That project E-GIS www.e-gis.org, is the basis for eGIS+ in the Lifelong Learning Programme (LLP). Ten partners from six European countries; Bulgaria, Lithuania, The Netherlands, Norway, Sweden and Portugal participated in E-GIS. During the

This thesis investigates the connection between open access – the free online availability and distribution of scientific and scholarly publications – and the ‘developing world’ from a post- development perspective. It takes a discourse analytical approach, drawing predominantly on Michel Foucault’s understanding of discourse. It aims to answer the following questions: - Which notions of science,

BACKGROUND: The earliest immune events induced by allergens are poorly understood, yet are likely essential to understanding how allergic inflammation is established. OBJECTIVE: We sought to describe the earliest signaling events activated by allergen and determine their significance to allergic inflammation. METHODS: A fungal-associated allergenic proteinase (FAP) or ovalbumin was administered on

Abstract in Norwegian Afhandlingens emne er måling af effekt af McKenzie behandlingsmetoden til patienter med uspecifik lænderygbesvær og udvikling af et diagnostisk klassifikationssystem til brug i primærsektoren. McKenzie metoden er en af de mest anvendte af fysioterapeuter i en række vestlige lande til undersøgelse og behandling af patienter med rygbesvær. Delarbejde I er den første publiceredeThe aims of this thesis were to investigate the effects of the Mc-Kenzie method of mechanical diagnosis and therapy compared with that of intensive dynamic strengthening training for patients with non-specific low back pain (NLBP), and to develop a clinical diagnostic classification system for use in primary care. The McKenzie method is one of the most common methods for examination and treatment

Most stars form in some sort of stellar cluster or association. In such clusters the number density of stars can be very high. Thus, single stars in such clusters may undergo frequent close encounters with other stars and exchange encounters with binary systems. The perturbation caused by the other star in a close encounter or by the companion star in a binary can have significant effects on the e

Popular Abstract in Swedish Det största bidraget till komplexitet i kemiska system kommer inte från de kemiska komponenternas molekulära struktur, utan deras växelverkan med varandra. Vi har mycket större kännedom om molekylär struktur i biologiska celler och organismer än om detaljerna i deras växelverkan. Ändå är det precis växelverkan mellan molekyler som utgör alla biologiska processer i grundThis thesis concentrates on the development, synthesis and evaluation of supramolecular systems, assembled from its components by means of hydrogen bonding, using the self-complementary 2-pyridone motif. The thesis is divided in two parts. 1) Supramolecular catalysis: Substrate selectivity is imposed on a derivative of Jacobsen's catalyst, an Mn(salen) complex with 2-quinolone hydrogen-bonding gr
