Aims: Although nitrogen (N) fixation by moss-associated bacteria is the main source of new N in N-limited ecosystems like arctic tundra, we do not know which nutrient, molybdenum (Mo) or phosphorus (P), is rate-limiting for sustaining this process in the long-term. Further, how moss-associated N2 fixation impacts the belowground microbial regulation of decomposition remains unresolved. Methods: Mo

Background & Aims: The I148M variant in PNPLA3 is the major genetic risk factor for non-alcoholic fatty liver disease (NAFLD). The liver is enriched with polyunsaturated triglycerides (PUFA-TGs) in PNPLA3-I148M carriers. Gene expression data indicate that PNPLA3 is liver-specific in humans, but whether it functions in adipose tissue (AT) is unknown. We investigated whether PNPLA3-I148M modifie

Background and Objectives: Hemodynamic stress during resistance training is often a reason why this training method is not used in cardiac patients. A lifting protocol that imposes rests between repetitions (IRRT) may provide less hemodynamic stress compared to traditional resistance training (TT). The aim of this study was to verify differences between set configurations on hemodynamic stress res

Objective. Involvement of the gastrointestinal (GI) tract is a rare complication of granulomatosis with polyangiitis (GPA) and microscopic polyangiitis (MPA). The aim was to describe frequency, diagnosis, treatment, and outcome of GI disease in a large series of patients in a single center. Methods.A database that includes all patients with GPA and MPA diagnosed since 1997 in a defined area of sou

Pre-school age (3–5 years) children are vulnerable to malnutrition due to poor dietary intake, dietary habits, and socio-economic conditions. Children from marginalized families are more vulnerable than non-marginalized families due to limited access to health- and nutrition-related services, besides other socio-economic factors. This study was done to assess the dietary intakes, patterns, and det

Swedish emergency services still have relatively limited resources and time for proactive fire prevention. Because of this, there is an extensive need for strategic working methods and knowledge to take advantage of spatial analyses. In addition, decision-making based on visualizations and analyses of their own collected data has the potential to increase the validity of strategic decisions. The o

The viability of a renewable electricity system depends on a relatively small share of hydropower storage resources to regulate climate variations and the spatially uneven distribution of renewable energy. By spatio-temporal coordination of hydropower production over larger regions, the energy storage demand will be reduced and contribute to a “virtual” energy storage gain that in Europe was found

Today, acquisition, creation and utilisation of knowledge are the key factors explaining economic development. Firms must constantly employ new knowledge and combine different types of knowledge in their activities to maintain competitiveness. This thesis examines the knowledge economy from two perspectives. The first focuses on the role of geographical proximity for interactive knowledge creation

Den statliga LSS-utredningen tycks inte ta hänsyn till FN:s konvention om rättigheter för personer med funktionsnedsättning, skriver forskarna Anna Bruce och Anna Nilsson.
