Skatter på energi har existerat i Sverige i snart 100 år. Skatt på drivmedel infördes 1924 som ett sätt att finansiera det snabbt växande vägväsendet. Principen om att skatter på drivmedel, fordon och väganvändning ska täcka transportsektorns samhällsekonomiska kostnader har sedan dess avspeglats i propositioner och utredningar även om den exakta tolkningen av detta ansvar har varierat. Beskattnin
Chronic breathlessness is a dominating symptom that restricts daily life for many people with cardiorespiratory disease [1]. Different dimensions of the symptom, such as the intensity, sensory qualities and emotional responses, can be assessed using the instruments Dyspnea-12 (D-12) [2] and the Multidimensional Dyspnea Profile (MDP) [3], which share similarities in the underlying constructs of wha
Effects of xylooligosaccharides (XOSs) as well as a mixture of XOS, inulin, oligofructose, and partially hydrolyzed guar gum (MIX) in mice fed a high-fat diet (HFD) were studied. Control groups were fed an HFD or a low-fat diet. Special attention was paid to the cecal composition of the gut microbiota and formation of short-chain fatty acids, but metabolic parameters were also documented. The XOS
Research in music, sound art and sound studies is not only a matter of listening and experiencing auditory phenomena. Neither is it limited to the study of scores, graphic notations or sonograms. With the still increasing expansion of practice-based research methods, many artists and scholars of music, sound art and sound studies now gain their knowledge through their creative practice, or through
The aim of this thesis is to critically investigate the discourses of Sweden’s Art and Music Schools (SAMS, kulturskolor in Swedish) connected to policy processes for the democratisation of music education for all children and adolescents. A further aim is to contribute to knowledge on the development and enactment of policy processes for the democratisation of music education.

Identification of the perivascular compartment as the point of exchange between cerebrospinal fluid (CSF) and interstitial fluid mediating solute clearance in the brain, named the glymphatic system, has emerged as an important clearance pathway for neurotoxic peptides such as amyloid-beta. However, the foundational science of the glymphatic system is based on rodent studies. Here we investigated w
Krav på innehåll i blodkomponenter, virustest och kvalitetskriterier regleras i ett EU-direktiv och i Socialstyrelsens föreskrifter. Blodtransfusioner är en vanlig och viktig medicinsk behandling.Det saknas nationella riktlinjer för transfusionsindikationer och uppföljning av blodtransfusioner i Sverige.Det finns medicinsk evidens för en generellt restriktiv transfusionsstrategi.Vid stora blödningSweden does not have a national blood authority and guidelines for blood transfusions are lacking, leading to varying routines of production and usage of blood in the different regions. The minimum quality requirements are defined in EU Directive 2002/98/EG and in the Swedish SOSFS 2009:28. The standard blood components are red blood cells, plasma and platelets, while special components such as ir
This paper represents a study of the geopolitical reasoning of the Georgian Orthodox Church (GOC) and its leader Patriarch Ilia II regarding the question of Georgia's territorial integrity. Does the GOC's territorial discourse complement or challenge Georgia's territorial nationalism? The empirical analysis of the geopolitical discourses of Patriarch Ilia II in the early 1990s and in the wake of t
We study the macroscopic dynamics of large networks of excitable type 1 neurons composed of two populations interacting with disparate but symmetric intra- and inter-population coupling strengths. This nonuniform coupling scheme facilitates symmetric equilibria, where both populations display identical firing activity, characterized by either quiescent or spiking behavior, or asymmetric equilibria
Electrical and chemical synapses shape the dynamics of neural networks, and their functional roles in information processing have been a longstanding question in neurobiology. In this paper, we investigate the role of synapses on the optimization of the phenomenon of self-induced stochastic resonance in a delayed multiplex neural network by using analytical and numerical methods. We consider a two
Onset and loss of synchronization in coupled oscillators are of fundamental importance in understanding emergent behavior in natural and man-made systems, which range from neural networks to power grids. We report on experiments with hundreds of strongly coupled photochemical relaxation oscillators that exhibit a discontinuous synchronization transition with hysteresis, as opposed to the paradigma
Many biological and neural systems can be seen as networks of interacting periodic processes. Importantly, their functionality, i.e., whether these networks can perform their function or not, depends on the emerging collective dynamics of the network. Synchrony of oscillations is one of the most prominent examples of such collective behavior and has been associated both with function and dysfuncti
Stroke affects millions each year. Poststroke brain edema predicts the severity of eventual stroke damage, yet our concept of how edema develops is incomplete and treatment options remain limited. In early stages, fluid accumulation occurs owing to a net gain of ions, widely thought to enter from the vascular compartment. Here, we used magnetic resonance imaging, radiolabeled tracers, and multipho
We investigated interactions within chimera states in a phase oscillator network with two coupled subpopulations. To quantify interactions within and between these subpopulations, we estimated the corresponding (delayed) mutual information that—in general—quantifies the capacity or the maximum rate at which information can be transferred to recover a sender's information at the receiver with a van
Kuramoto oscillators are widely used to explain collective phenomena in networks of coupled oscillatory units. We show that simple networks of two populations with a generic coupling scheme, where both coupling strengths and phase lags between and within populations are distinct, can exhibit chaotic dynamics as conjectured by Ott and Antonsen [Chaos 18, 037113 (2008)]. These chaotic mean-field dyn
