Borrelia burgdorferi sensu lato and Anaplasma phagocytophilum in Ixodes ricinus ticks in Brønnøysund in northern Norway

2013

Ticks are important vectors of disease for both humans and animals. In Europe, Lyme borreliosis is the most abundant tick-borne human disease, whereas anaplasmosis, or tick-borne fever, is the most widespread tick-borne infection in domestic animals. However, knowledge about the prevalence of the causative disease agents in questing ticks in the northern range of their distribution in Norway is missing. Ixodes ricinus ticks were therefore collected by flagging vegetation in Brønnøysund, an area near the Arctic Circle in Norway where ticks have been abundant for decades. Ticks were analysed for infection with Borrelia burgdorferi sensu lato and Anaplasma phagocytophilum by real-time PCR ampl…

Streamwater responses to reduced nitrogen deposition at four small upland catchments in Norway

2020

AbstractReduced emissions of nitrogen (N) in Europe have resulted in decreasing atmospheric deposition since 1990. Long-term data (1988–2017) from four small Norwegian catchments located along gradients in N deposition, rainfall, and organic carbon (C) show different responses to 25–30% reductions in N deposition during the same period. At three sites the decreased N deposition caused reduced leaching of nitrate to surface water, whereas the westernmost site showed no decrease, probably due to thin soils with low C:N ratio, poor vegetation cover and high precipitation. The loss of total N to streamwater constituted 30–50% of the N deposition. Losses via denitrification are unknown but assum…

From cars to bikes – the feasibility and effect of using e-bikes, longtail bikes and traditional bikes for transportation among parents of children a…

2017

Abstract Background The present study aims to increase bicycling and level of physical activity (PA), and thereby promote health in parents of toddlers, by giving access to different bicycle types. There is a need for greater understanding of e-bikes and their role in the transportation network, and further effects on PA levels and health. Moreover, longtail bikes could meet certain practical needs not fulfilled by e-bikes or traditional bikes, hence increased knowledge regarding their feasibility should be obtained. No previous studies have investigated whether providing an e-bike or a longtail bike over an extended period in a sample of parents of toddlers influence objectively assessed a…

Associations between structures, processes and outcomes in inter-municipal cooperation in out-of-hours services in Norway: A survey study

2020

Abstract Inter-municipal cooperation (IMC) has gained widespread recognition as a beneficial strategy for improving efficiency and quality in the provision of out-of-hours emergency care services (OOH services). Little attention, however, has been given to the additional costs of cooperation and the relational processes through which benefits and costs are likely to result. Based on survey data from 266 (77%) Norwegian municipalities involved in IMC in OOH services in 2015, this study aimed to investigate how the structure (governance form, complexity and stability) and quality (trust and consensus) of cooperation processes interact to influence the perceived outcomes (benefits and costs) o…

Job insecurity and sickness absence: Correlations between attrition and absence in 36 occupational groups

2012

Aims: To investigate how job insecurity, as indicated by attrition rates out of employment, affects sickness absence among remaining workers. Methods: A longitudinal analysis investigated how the percentage of workers absent due to sickness was affected by attrition out of employment in Norwegian Labour Force Surveys from 1997 to 2005, between 31 quarterly observations at the level of 36 occupational groups. Results: Rising attrition is associated with more sickness absence. Conclusions: Previous research has argued that job insecurity can lead to more absence because of a stressor effect as well as to less absence because of a disciplinary effect. This research indicates that the stressor…

Energy measurements at Skarpnes zero energy homes in Southern Norway: Do the loads match up with the on-site energy production?

2017

Five houses are designed as zero-energy homes in Skarpnes, Norway. The energy goal is to achieve net zero-energy balance on an annual basis. The houses have heat pumps and solar cells (PV). Energy use and delivered energy have been monitored from June 2015. Variations between calculations and measurements are explained by technical and non-technical reasons. For the first year, higher than expected energy loads result in a solar energy cover factor of 65–87% of delivered electricity. The PV generation performs satisfactorily, hence, it may be possible to achieve energy goals during later years provided technical adjustments or behavioral changes. Acknowledgements. This report has been writt…

Hybrid activated sludge/biofilm process for the treatment of municipal wastewater in a cold climate region: a case study.

2011

A hybrid activated sludge/biofilm process was investigated for wastewater treatment in a cold climate region. This process, which contains both suspended biomass and biofilm, usually referred as IFAS process, is created by introducing plastic elements as biofilm carrier media into a conventional activated sludge reactor. In the present study, a hybrid process, composed of an activated sludge and a moving bed biofilm reactor was used. The aim of this paper has been to investigate the performances of a hybrid process, and in particular to gain insight the nitrification process, when operated at relatively low MLSS SRT and low temperatures. The results of a pilot-scale study carried out at the…

Organic material dissolved during oxygen-alkali pulping of hot-water-extracted spruce sawdust

2016

Untreated and hot-water-extracted (HWE) Norway spruce (Picea abies) sawdust was cooked using the sulfur-free oxygen-alkali (OA) method under the following conditions: temperature, 170 °C; liquor-to-wood ratio, 5:1 L/kg; and NaOH charge, 19% on the oven-dry sawdust. In comparison with earlier studies conducted with birch sawdust, the spruce cooking yield data, together with the amount of the pulp rejects (78% to 86% for reference pulps from the initial feedstock and 73% to 83% for pulps from the HWE feedstock), revealed that the pretreatment stage prior to spruce OA pulping caused different effects on pulping performance. The analyses of the three main compound groups (i.e., lignin, volatile…
