Postnatal intestinal development is a very dynamic process characterized by substantial morphological changes that coincide with functional adaption to the nutritional change from a diet rich in fat (milk) to a diet rich in carbohydrates on from weaning. Time-resolved studies of intestinal development have so far been limited to investigation at the transcription level or to single or few proteins

The general objective of this thesis was to increase the knowledge of how mental health and school performance are associated and how interventions may be designed and implemented to enhance the two.The data used in the four quantitative studies on which this thesis is based were derived from two age cohorts of students attending 14 elementary schools in two cities in the southern part of Sweden.

Climate change is expected to cause extensive vegetation changes in the Arctic: deciduous shrubs are already expanding, in response to climate warming. The results from transect studies suggest that increasing shrub cover will impact significantly on the surface energy balance. However, little is known about the direct effects of shrub cover on permafrost thaw during summer. We experimentally quan

Aim: To describe drug use and healthcare utilisation among persons with intellectual disabilities (ID) and dementia in comparison to persons with ID only and dementia only. Method: From the group of persons with ID (n=7936), 216 individuals with dementia were identified. 81 persons with dementia were identified from a general population sample matched by age and sex. Information on outcomes was co

Vi lever längre och befolkningen blir därför allt äldre. Som vårt nuvarande pensionssystem är uppbyggt måste vi jobba två tredjedelar av vårt vuxna liv för att systemet ska fungera. Därför ligger det förslag om att justera pensionsåldern till 69 år. Men för att fler ska kunna och vilja arbeta till en högre ålder krävs en rad organisatoriska förändringar på dagens arbetsplatser. Att gå i pension är

Samhället förändras kontinuerligt. Hur samhällsutvecklingen ser påverkar energiefterfrågan och utsläppen av växthusgaser. Sedan den industriella revolutionens genombrott har Sverige gått igenom tre större samhällsomställningar som har haft en stor inverkan på energisystemet och därmed utsläppen. Syftet med denna underlagsrapport är att diskutera drivkrafterna bakom dessa omställningar och vilka lä

Background: Several countries have increased patients' abilities to choose their health care providers, frequently under the assumption that patients are themselves the best agents to make such decisions. In parallel, national and regional health authorities have enhanced access to Internet based information sources (IBIS) to assist patients in making an informed choice. Relatively little, however

Several strategic interactions over social networks display both negative and positive externalities at the same time. E.g., participation to a social media website with limited resources is more appealing the more of your friends participate, while a large total number of participants may slow down the website (because of congestion effects) thus making it less appealing. Similarly, while there a

We propose a dynamical model for cascading failures in single-commodity network flows. In the proposed model, the network state consists of flows and activation status of the links. Network dynamics is determined by a, possibly state-dependent and adversarial, disturbance process that reduces flow capacity on the links, and routing policies at the nodes that have access to the network state, but a

It is widely believed that deciduous tundra-shrub dominance is increasing in the pan-Arctic region, mainly due to rising temperature. We sampled dwarf birch (Betula nana L.) at a northeastern Siberian tundra site and used dendrochronological methods to explore the relationship between climatic variables and local shrub dominance. We found that establishment of shrub ramets was positively related t

Recently observed Arctic greening trends from normalized difference vegetation index (NDVI) data suggest that shrub growth is increasing in response to increasing summer temperature. An increase in shrub cover is expected to decrease summer albedo and thus positively feed back to climate warming. However, it is unknown how albedo and NDVI are affected by shrub cover and inter-annual variations in

Introduction. This paper reports findings from an on-going analysis of how pre-school teacher trainees position their identities, as learners and future pre-school teachers, as information activities are performed in a Facebook Group and on a blog. Method. The analysis is based on results from an ethnographic study at a pre-school teacher-training programme at a Swedish university. Participant obs

Mixed cultures of a heterotrophic nitrifier/aerobic denitrifier, Thiosphaera pantotropha, and an autotrophic nitrifier, Nitrosomonas europaea, were grown in chemostats under dual ammonia-and acetate limitation. Because of simultaneous nitrification and denitrification by T. pantotropha, the activity of the cultures was evaluated from nitrogen balances as complete as possible. Under most conditions

In order to understand where and how the Swedish public access their medicines, especially prescribed medicines, an online survey was conducted as a pilot study during April and May 2016. Among a collection of 155 answers, the data shows that, although a majority of the respondents feel hesitated and negative towards shopping prescribed medicines online, a tendency is demonstrated that people woul
