Studies of natural radiative lifetimes and hyperfine structure have been performed for group IIA and IIIA atoms. Different laser spectroscopic techniques such as PUMOLS, time-resolved laser spectroscopy, using transient recorder, and collimated atomic-beam experiments have been used. These methods employ cw or pulsed dye laser systems. The lifetime measurements revealed several cases in barium and

Participatory design (PD) has taken as its ideal that designers and users should engage in an equal language game. When we apply PD in contexts where some of the users involved are weak, ill, or have impairments, this assumed equality can no longer be an ideal. The workshop explores new ideals for participatory design in non-work settings with highly heterogeneous user constellations.

This article documents new sightings of the leafcutting bee Megachile lagopoda (L.) in Åhus, Scania, Sweden on cotton thistle in a pine forest. The importance of areas of undeveloped land as habitat for rare species and the dispersal range of the bee are discussed.

Opera improvisation at The Malmö Academy of Music has been a pedagogical and artistic experiment. This is the final account concerning this pedagogical and artistic research project. Singers who are studying classical singing at the bachelor and master programmes of theacademy have participated. The account includes historical and theoretical reflections on the subject and comments on the work in

Popular Abstract in Swedish Denna doktorsavhandling är en delstudie i ett större projekt som syftar till att utveckla Artificiell fotosyntes för att framställa ett värdefullt bränsle, vätgas, från solenergi och vatten. Vår typ av Artificiell Fotosyntes syftar till att framställa syntetiska “superämnen” som kan härma nyckelsteg i den naturliga fotosyntesen. Våra artificiella ”superämnen” skall kunnIn natural photosynthesis, solar energy is converted to chemical energy by photosynthetic reaction centers. In green plants and algae, Photosystem II (PSII) and Photosystem I (PSI) absorb light and utilize the charge separation reactions to convert solar energy to chemical energy. The energy is later stored in form of energy- rich substances formed in reductive biosynthetic reactions. The electron

The purpose of this licentiate thesis is to investigate the following hypothesis in a case study: "Occupants of buildings with a quality labeled indoor environment experience a better indoor environment than occupants of buildings with normal planning and construction." The aim of the case study is to compare the outcome of using a quality system for indoor environment with a normal quality system

An automatic time sequence filter sampler has been developed for atmospheric aerosol particle sampling of ambient air and subsequent analysis for elemental composition using the proton beam of a Van de Graaff accelerator. Some features of the operation of the sampler are given, the retention of particles by the filter material are discussed, examples of the type of data obtained are presented, and

Growing and eating food are cultural practices that simultaneously make physical bodies, shape landscapes, and produce racial (together with class/ethno/spatial) knowledge and identity. This chapter strives to complement the large body of work on race and racism in Brazil and elsewhere with an exploration of how some people in the Brazilian state of Bahia experience and communicate racialized iden

Reviews and practice guidelines for paediatric obsessive-compulsive disorder (OCD) recommend cognitive-behaviour therapy (CBT) as the psychological treatment of choice, but note that it has not been sufficiently evaluated for children and adolescents and that more randomized controlled trials are needed. The aim of this trial was to evaluate effectiveness and optimal delivery of CBT, emphasizing c

Popular Abstract in Swedish Hur förklarar vi vad som hände efter Big Bang? Hur är det möjligt att titta 14 miljarder år tillbaka i tiden, isolera de första miljarddelarna av en sekund, och studera vad som pågår precis där och då? Svaret är såklart, att vi inte kan det. Det vi kan göra, är att om och om igen återskapa några viktiga aspekter av de förhållanden som rådde då, och studera vad som händeA new energy regime has recently become accessible in collisions at the Large Hadron Collider at CERN. Abundant in hadron collisions, the two-jet final state explores the structure of the constituents of matter and the possible emergence of new forces of nature, in the largest momentum transfer collisions produced. The results from searches for phenomena beyond the Standard Model in the dijet angu

The paper provides an exploratory empirical survey of Application Service Providers (ASPs) and their clients. The research question is: what do Small and Medium-sized Enterprises (SMEs) base their decision on when adopting the ASP concept? The concept, ASP, consists of software vendors, and an ASP enterprise, which act as a third part firm in a business model. For its clients it forms a strategy t
