MRI provides unsurpassed soft tissue contrast, but the inherent low sensitivity of this modality has limited the clinical use to imaging of water protons. With hyperpolarization techniques, the signal from a given number of nuclear spins can be raised more than 100 000 times. The strong signal enhancement enables imaging of nuclei other than protons, e.g. C-13 and N-15, and their molecular distrib
We prove the existence of the old and metal-rich moving group HR 1614. This is done using the new Hipparcos parallaxes in combination with metallicities derived from Strömgren photometry, supported by dynamical simulations of the evolution of old moving groups in the galactic potential. A new selection criterion for this moving group is presented as well as a new, extended sample of probable membe
The thermotropic phase behaviour and phase structure of crystalline and non-crystalline n-tetradecyl-beta-D-maltoside (C(14)G(2)) and n-hexadecyl-beta-D-maltoside (C(16)G(2)) have been investigated by means of differential scanning calorimetry and X-ray techniques. Upon lyophilisation, both compounds form a solid, lamellar phase comprising disordered head groups and hexagonally packed alkyl chains
Tidigare forskning om motivation vid lärande har tenderat att fokusera på attributioner (de tolkningar elever och andra gör av orsaker till framgångar och misslyckanden) självuppfattning, målorientering och elevers autonomi. Denna avhandling syftar dels till att beskriva bakgrunden och skolgången för de elever som går på gymnasiets estetiska programs musikgren, dels till att mäta den motivation deIn previous studies research on motivation in education has tended to be focused on attribution (perceived causes of success and failure), self perception, goal orientation and autonomy. This thesis aims to describe the background and schooling of music students and to measure their motivation for music education. Motivation is viewed as a cognitive process, which influences learning through achie
Restless legs syndrome (RLS) is characterized by intense restlessness and unpleasant creeping sensations deep inside the lower legs. The symptoms appear when the limbs are at rest and are worst in the evening and at night. They force the patients to keep moving their legs, and sometimes to get out of bed and wander about. Periodic limb movements of the extremities (PLM) are common during sleep thu
