Spatial and temporal dynamics of subarctic birch forest carbon exchange

Popular Abstract in English The long-term stability of the global terrestrial carbon sink has been a matter of concern in that a weakening would have serious consequences for atmospheric CO2 concentrations and, hence, for further changes in climate. High northern latitudes are of special importance for the global carbon budget as they store large amounts of organic matter in the soil and are expecHigh northern latitudes are of special importance for the global carbon budget as they store large amounts of organic matter in the soil and are expected to be the most strongly affected by climate change. Here we investigate carbon exchange in the subarctic mountain birch forest growing on the limit where tree growth is possible. The study sites are located close to the Abisko village in norther

Estimation of absorbed PAR across Scandinavia from satellite measurements. Part II: modeling and evaluating the fractional absorption.

The aim of this study is to generate a quality-controlled sub-kilometer dataset of the fraction of absorbed photosynthetically active radiation (FAPAR) across Scandinavia from satellite. FAPAR is required for estimating the amount of PAR absorbed (APAR) by vegetation, which in turn allows for estimation of carbon uptake. In this study, FA-PAR was modeled from normalized difference vegetation index

Bus travel safety - a travel chain perspective

The injury risk for bus passengers is low compared to car users. However, bus passengers also run the risk of sustaining injuries as vulnerable road users: as pedestrians or cyclists to and from the bus stop. Among vulnerable road users, seniors are a particularly important group. Hitherto, injury data have mainly been based on police-reported accidents. These accidents reveal bus occupant safety,

A Tale of Two Clusters: Sharing Resources to Compete

“The death of distance” has become the battle cry of a modern generation of managers, policy makers and scientists who embrace the new globalized economy and its promise of frictionless exchange across the world. While highly influential, this view does not, however, stand unchallenged. Over the last 15 years, there has been a growing interest in the geographical clustering of industry. Well-known

Integrating the “dead capital” in models of cadastral systems

Cadastral Systems have developed during the latest decades, impelled by improved information technology. Cadastral projects have become more strategic in a development perspective, with expected long-term returns in economic growth.

An improvement of an existent information system requires an understanding of the basis of the current model, its coverage and the processes of change. The l

Äldrevård, förvaltning, legitimitet och skäliga levnadsvilkor

The administration’s legitimacy of the constitutional democracy consist in laws being applied in accordance with the principles which are their foundation. Care about the elderly is the municipals’ responsibility, and this task is regulated in the law of social services and the law of health and healthcare. The legislation grant individual elderly the right to a standard of living that in the law

SME creation facilitation process at Universities

Much research on SMEs is aimed at researching SMEs after the fact that they have become SMEs. However all SMEs as well as larger companies start as an idea in the head or heads of one or many persons - the prospective entrepreneurs. The purpose of this paper is to investigate how SMEs can be created by transforming ideas into real companies. More specifically we will investigate if and how Univers

Health Claims in the EU and their Scientific Substantiation

A new Regulation on nutrition and health claims came into force in 2007 with implementation during a three-year period and will harmonise this area within the European Community. It makes provision for health claims on foods, including reduction of disease risk claims, and thus recognises the importance of food and nutrition for health. Member states have provided suggestions for claims regarding

Service, Regulations, and Ports : An Actor-Network perspective on the social dimension of Service-Dominant Logic

Something has happened in the field of Service Studies. With the introduction of what has been called Service Dominant Logic a large proportion of the established theories related to service as a phenomenon has been challenged. From previously having been defined as something different from the tangible things we buy (goods); i.e. a residual, service defined out of what service is not, the new lin

No serological indications that systemic lupus erythematosus is linked with exposure to human parvovirus B19

OBJECTIVES: Infectious agents like parvovirus have been implicated as exogenous factors that could trigger onset of systemic lupus erythematosus (SLE). A number of case reports describing a SLE-like presentation of acute human parvovirus B19 infection have been published, but no systematic investigation of the actual seroprevalence in epidemiologically defined SLE populations has previously been r

Willingness to pay for health improvements of physical activity on prescription.

AIMS: To estimate the willingness to pay for health improvements among participants in the programme "Physical Activity on Prescription". The objective was also to examine predictors such as income, education level, health status, activity level and BMI, differences for long- and short-term health effects of physical activity and differences between a high- and low-intensity activity group. METHOD

Patients' perceptions of their participation in discharge planning after acute stroke.

Aims and objectives. To describe stroke patients' perceptions of their participation in the discharge planning process and identify correlates of perceived participation. Background.
