- Objective To investigate the association between vaccinations in adults and the risk of developing rheumatoid arthritis (RA). Methods Data from the Swedish population-based Epidemiological Investigation of RA case-control study encompassing 1998 incident cases of RA aged 18-70 years and 2252 randomly selected controls matched for age, sex and residency were analysed. Those vaccinated within 5 years before disease onset were compared with those not vaccinated by calculating OR with 95% CI. Results Vaccinations neither increased the risk of RA overall (OR 1.0, 95% CI 0.9 to 1.1) nor the risk of two major subgroups of RA (antibodies to citrullinated peptide-positive (ACPA-positive) and ACPA-negative disease). Furthermore, vaccinations did not increase the risk of RA in smokers or carriers of HLA-DRB1 shared epitope alleles, two groups with established risk factors for RA. Conclusions In this case-control study of incident cases of newly diagnosed RA, no increased risk of RA following immunisation was observed for vaccinations overall or for any specific vaccination. This indicates that immunological provocation of adults with commonly used vaccines in their present form carries no risk of RA. These findings should be implemented among public healthcare providers in order to encourage vaccinations according to recommended national vaccination schedules.

- It is generally accepted that human activities have a large influence on global climate. In order to minimize human impact on global warming, regulations and agreements may be introduced for all CO2 generating sectors. Therefore, measures to reduce CO2-emissions will be of importance to the industrial sector. Strategic decisions and long-term thinking are needed to comply with the regulations and to fulfil the agreements.The pulp and paper industry is an energy intensive sector with relatively large potentials to accomplish energy efficiency measures that result in reduction of CO2-emissions. To settle the cost-effectiveness for each measure a number of system parameters have to be considered, such as investment costs, boundary conditions and reference systems.This paper presents two methods, pinch technology and the MIND method. These methods are used for analysis of industrial energy systems considering different parameters and aspects. Pinch technology is used for thermodynamic and economic evaluation of process integration possibilities and the MIND method is used for strategic evaluation of different energy efficiency measures. Foundation for long-term decision-making can be obtained by co-ordinating the results from the two methods. In this paper, cost-effectiveness has been determined for different energy efficiency measures. The measures are non-conventional evaporation and heat pumping. The case studied is from a Swedish board mill. Economic potentials and consequences for these CO2-reducing measures are discussed from both an industrial and a societal perspective.

Young children's representations of peers' distress: Associations to children's social functioning and acceptance of distressed peers

- Children's mental representations of situations involving another child's distress were examined in two studies. Study 1 examined 3- to 7-year-old children's (n = 44) ideas about what victims and bystanders would think, feel and do in hypothetical situations. In Study 2, 7- to 8-year-olds (n = 40) described their own cognitive response to situations in which they were confronted with another's distress. In both studies, representational bias was examined in relation to children's display of prosocial and aggressive behavior and in relation to their acceptance of distressed peers. Although not entirely consistent, findings indicate that three types of representational biases are associated with low levels of considerate behavior and with relatively low acceptance of distressed peers: (a) mentally representing the victim's problem without giving thought to its implications for the victim, (b) significantly reducing the emotional significance of the problem and (c) exaggerating negative aspects of the problem.

Discontinuous Least-Squares finite element method for the Div-Curl problem

- In this paper, we consider the div-curl problem posed on nonconvex polyhedral domains. We propose a least-squares method based on discontinuous elements with normal and tangential continuity across interior faces, as well as boundary conditions, weakly enforced through a properly designed least-squares functional. Discontinuous elements make it possible to take advantage of regularity of given data (divergence and curl of the solution) and obtain convergence also on nonconvex domains. In general, this is not possible in the least-squares method with standard continuous elements. We show that our method is stable, derive a priori error estimates, and present numerical examples illustrating the method. © Springer-Verlag 2005.

Factors influencing limit values for pine needle litter decomposition : A synthesis for boreal and temperate pine forest systems

Tidskriftsartikel (refereegranskat)abstract
- We synthesized available data for decomposition of pine (Pinus) needle litter in pine forests to determine the litter chemical characteristics and climate factors that explained variation in the limit value, i. e. the level of accumulated mass loss at which the decomposition process either continues at a very low rate or possibly stops. Our data base included 56 separate studies on decomposition of pine needle litter, spanning Scots pine, lodgepole pine, Aleppo pine, stone pine and white pine, mainly incubated at the site of collection. Studies had 5 to 19 samplings, on average 10, and the decomposition was followed to a mass loss ranging from 47 to 83%, on average 67%. The periods from 3.0 to 5.4 years, on average 3.9 years, were of sufficient duration to allow estimates of limit values of decomposition. We used a linear mixed model with regression effects to relate limit values to potential explanatory variables, namely the sites' long-term mean annual temperature (MAT) and mean annual precipitation (MAP) and to substrate-chemistry factors. Regarding the latter, we explored two models; one that included initial concentrations of water solubles, lignin, N, P, K, Ca, Mg, and Mn and one that included only lignin, N, Ca, and Mn to focus on those nutrients known to influence lignin degradation. Using backward elimination significant explanatory variables were determined. For litter decomposed in its site of origin we found the limit value to depend mainly on the initial concentration of Mn, with higher Mn concentrations resulting in higher accumulated mass loss. Thus, litter with higher Mn reached a higher limit value and left a smaller stable fraction. This is likely due to the fact that Mn is an essential component of ligninolytic enzymes important for degrading litter in the later stages of decomposition. Manganese has received little attention in decomposition studies to date. Given its significance in this synthesis, the role of Mn in influencing variation in the late stages of decomposition among ecosystems and among litters of other genera besides Pinus deserves further attention.

Tidskriftsartikel (populärvet., debatt m.m.)abstract
- Silvergruvan i Kongsberg, ett förindustriellt tekniskt kulturminne, rymmer numera Norsk Bergverksmuseum. Museet grundades redan 1938 som ett driftsmuseum för gruvan och öppnades för allmänheten 1945. Museet äger bl a världens främsta samling av trådsilver; här finns också redskap och föremål från gruvtiden.
