Forskningsöversikt (refereegranskat)abstract
- Presently under construction in Lund, Sweden, the European Spallation Source (ESS) will be the world’s brightest neutron source. As such, it has the potential for a particle physics program with a unique reach and which is complementary to that available at other facilities. This paper describes proposed particle physics activities for the ESS. These encompass the exploitation of both the neutrons and neutrinos produced at the ESS for high precision (sensitivity) measurements (searches).

-
Tidskriftsartikel (refereegranskat)abstract
- The NNBAR experiment for the European Spallation Source will search for free neutrons converting to antineutrons with a sensitivity improvement of three orders of magnitude compared to the last such search. This paper describes progress towards a conceptual design report for NNBAR. The design of a moderator, neutron reflector, beamline, shielding and annihilation detector is reported. The simulations used form part of a model which will be used for optimisation of the experiment design and quantification of its sensitivity.

Gymnasieelevers presentationer av relationer mellan miljö och människor – en studie om utbildning för hållbar utveckling

Licentiatavhandling (övrigt vetenskapligt/konstnärligt)abstract
- This study investigates how upper secondary school students constitute relations between the environment and humanity. The aim of the study is to analyse relations that emerge between and within the Earth´s major systems (humanity included) and how these relations are composed when students are faced with a fictional decision of consuming a pair of jeans. Using workshop as a data collection method, students creatively visualize their discussions through participatory modelling in groups. The results of the study are based on the analyses of the concluding presentations of the completed models.The results show difficulties in submitting relations between the three dimensions of the concept of sustainable development together with a dualistic worldview, indicating a lack of complexity in the presentations. Therefore, a gap can be identified between the empirical results and the aims of education for sustainable development (ESD) that, according to the Ministry of Education and Research, should be a part of Swedish upper secondary education. In addition, a gap between the steering documents for the Swedish upper secondary schools and the UNESCO guidelines on ESD is revealed, consisting of the latter more distinctly promoting systems thinking and embracing pluralism. Three national programmes are represented in the study; social science, science and economics. Differences between the three are established. Groups with a focus on social science present complexity to higher extent than groups on science orientation. Groups with a focus on economics present least complexity in their presentations.

Tidskriftsartikel (refereegranskat)abstract
- The NNBAR experiment for the European Spallation Source will search for free neutrons converting to antineutrons with an expected sensitivity improvement of three orders of magnitude compared to the last such search. This paper describes both the simulations of a key component for the experiment, the neutron optical reflector and the expected gains in sensitivity.

An increase in sudden unexpected cardiac deaths among young Swedish orienteers during 1979-1992

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: Sixteen cases of sudden unexpected cardiac death, 15 males and one female, are known to have occurred among young Swedish orienteers from 1979 to 1992, of which seven cases occurred between 1989 and 1992. This is considered to be indicative of an increased death rate. RESULTS: Histopathological evaluation showed myocarditis in a higher than expected proportion of cases. In one such case, which we studied before the sudden unexpected death occurred, the victim had suffered a Chlamydia pneumoniae infection verified by serology, and a nucleotide sequence was found in the heart and lung by means of the polymerase chain reaction (PCR) that hybridized with a probe specific for that organism. Male Swedish orienteers do not, however, seem to have an increased rate of exposure to this agent. No further sudden unexpected deaths among young orienteers have occurred over the past 3.5 years. At the beginning of that period, attempts were made to modify training habits and attitudes.
