The major challenge in the development of new polymer membranes for fuel cells lies currently in the demand for durable membranes that allows fuel cell operation at high temperatures without extensive humidification requirements. Access to these membranes promises important benefits concerning the complexity, cost and performance of the fuel cell system. In this context, membranes functionalized w

In this work, we present results from atomistic simulations of gold nanowires under axial compression, with a focus on examining the effects of both axial and surface orientation effects on the buckling behavior. This was accomplished by using molecular statics simulations while considering three different crystallographic systems: /{100}, /{110} and /{110}{100}, with aspect ratios spanning from 2

The subject of this thesis is intellectual property and protection of non-commercial societal interests. The study is divided in two main parts. The first part deals with the provision of the Swedish Copyright Act laying down that literary and artistic works may not be performed or reproduced publicly after the death of their author in a manner that violates cultural interests (protection for clas

This paper summarizes the recent calculations of the masses and decay constants of the pseudoscalar mesons at the two-loop level, or NNLO, in Partially Quenched Chiral Perturbation Theory (PQxPT). Possible applications include chiral extrapolations of Lattice QCD, as well as the determination of the low-energy constants (LEC:s) of QCD

Popular Abstract in Swedish Under fostertiden är fostret beroende av tillförsel av syre och näringsämnen via moderkakan och navelsträngen, och koldioxid som bildas vid dess ämnesomsätt-ning avges i motsatt riktning. Under förlossningen ökar trycket i livmodern vid varje värk, så att tillförseln av syrerikt blod från modern till moderkakan till-fälligt nedsätts. Det finns också en risk att navelstrAcidaemia at birth is a result of an impaired intrauterine gas exchange. Between 1988 and 1996, acid-base balance in cord artery blood pH was assessed in 23 016 of 27 064 newborns (85%). Obstetric risk factors for acidaemia (cord artery pH < 7.05) were identified in a case-control study. Independent risk factors were breech delivery, administration of oxytocin or pethidine, cord entanglement and m

We have developed a tandem of undergraduate courses for teaching XP and coaching of XP teams. This paper focuses on the coaching course and the coaching practices we have developed. The tandem of courses enables us to give a challenging and interesting course for the coaches, and, at the same time, allows us to afford on-site coaches for the younger students, providing them with a high quality env

Being stimulated by the recent identification of the two-phonon wobbling excitation, first I make a brief survey of various two-phonon states in nuclear physics, in connection with experimental observations. Then, I discuss the wobbling-phonon excitation in the presence of particle alignments, which is nicely pinned down in the recent experiments of the nucleus Lu-163(71)92.

This is a basic textbook in the psychology of religion, originally published in 1985, used at almost all basic courses at university level in Sweden and other Scandinavian countries. The book has been revised four times (1989, 1993, 1999, 2000). New chapters on contemporary spirituality and coping theory have been added.
