Particle formation events were analysed from aerosol number size distribution data collected at a background station in southern Sweden between February 2001 and May 2004. Events occurred on about 36% of all days and were favoured by high global radiation values. The clearest events (class I, 20% of all days) were observed when the formation rate of activated hypothetical clusters around 1 nm diam

Genital warts are caused by human papillomavirus (HPV). HPV is a leading cause of anogenital malignancies and a role of HPV in the aetiology of oro-pharyngeal cancers has been demonstrated. The frequency of oral HPV infection in patients with genital warts and the association between concomitant genital, anal and oral infection is unclear. A total of 201 men and women with genital wart-like lesion

REVEALS-based quantitative reconstruction of Holocene vegetation cover (expressed in plant functional types. PFTs) is used in the LANDCLIM project to assess the effect of human-induced land-cover change on past climate in NW Europe. Using the Czech Quaternary Pollen Database, this case study evaluates the extent to which selection of data and input parameters for the REVEALS model applications wou

The expansion of wind power in Sweden has brought increasing conflicts between the wind power industry and the interests of the military forces. This paper analyses the reasons for these perceived conflicts and suggests solutions for mitigating at least some of the problems. The analysis is based on literature studies, several semistructured interviews and workshops with stakeholders in Sweden, De

Predicted alterations in belowground plant-allocated C as a result of environmental change may cause compositional shifts in soil microbial communities, and it has been hypothesized that such alterations will influence C mitigation in forest ecosystems. In order to investigate to what degree living trees influence the abundance and activity of mycorrhizal fungi, saprotrophic fungi, and bacteria we

The predominantly populated conformation of carbohydrates in solution does not necessarily represent the biologically active species; rather, any conformer accessible without too large an energy penalty may be present in a biological pathway. Thus, the conformational preferences of a naphthyl xyloside, which initiates in vivo synthesis of antiproliferative glycosaminoglycans, have been studied by

We investigated atmospheric aerosol particle dynamics in a boreal forest zone in northern Scandinavia. We used aerosol number size distribution data measured with either a differential mobility particle sizer (DMPS) or scanning mobility particle sizer (SMPS) at three stations (Varrio, Pallas and Abisko), and combined these data with the HYSPLIT (Hybrid Single Particle Lagrangian Integrated Traject

Background: Thailand is not only a popular destination for Swedish tourists, it is also the foreign country where the largest numbers of Swedish males contract HIV. This study investigated sexual risk-behaviour of Swedish men who have sex with commercial sex workers (CSW) in Thailand. Method: Eligible men were approached on location in red-light districts of Pattaya and Bangkok with a self-adminis
