In this work, we study YouTube traffic characteristics in a medium-sized Swedish residential municipal network that has 2600 mainly FTTH broadband-connected households. YouTube traffic analyses were carried out in the perspective of video clip category and duration, in order to understand their impact on the potential local network caching gains. To the best of our knowledge, this is the first tim

To study cortical re-organisation after acute hand deafferentation, we investigated 10 experimental subjects and 10 controls for function in the left hand, before, during and after tourniquet induced anaesthesia of the right hand. fMRI was performed in three experimental subjects. Tourniquet-induced right hand anaesthesia resulted in rapid significant improvement in grip strength, tactile discrimi

There is an increasing consensus that individual adaptive capacities are critical to successfully adapt to climate change and achieve sustainable development. However, little is known about adaptive practices, particularly in developed countries. Against this background, this paper investigates the strategies used by Swedish citizens to adapt to (changing) climatic variability and extremes. It off

UV-B radiation effects on nutrient concentrations in above-ground organs of maize were investigated at silking and maturity at different levels of applied nitrogen under field conditions. The experiment simulated a 20% stratospheric ozone depletion over Portugal. At silking, UV-B increased N, K, Ca, and Zn concentrations, whereas at maturity Ca,Mg, Zn, and Cu increased and N, P and Mn decreased in

In this study, we sought evidence for alpha-synuclein (ASYN) expression in oligodendrocytes, as a possible endogenous source of ASYN to explain its presence in glial inclusions found in multiple system atrophy (MSA) and Parkinson's disease (PD). We identified ASYN in oligodendrocyte lineage progenitors isolated from the rodent brain, in oligodendrocytes generated from embryonic stem cells, and in

Properties of nonionic triblock copolymers of poly(ethylene oxide) (PEO) and poly(propylene oxide) (PPO) (EOnPOmEOn) in aqueous solution and their interaction with the ionic surfactants sodium dodecyl sulfate and hexadecyltrimethylammonium chloride have been investigated by static and dynamic light scattering, high sensitivity differential scanning, and isothermal titration calorimetry. The studie

Popular Abstract in Swedish Hormonerna vasopressin och oxytocin frisätts från hypofysens baklob. Hypofysen är en körtel, som är belägen på undersidan av hjärnan och utsöndrar en rad olika hormoner vilka i sin tur påverkar och reglerar aktiviteten i en mängd andra organ. Vasopressin medverkar till regleringen av vatten- och saltbalansen i kroppen, men verkar också sammandragande på icke-viljestyrdVasopressin and oxytocin seem to have pivotal roles in the pathophysiology of primary dysmenorrhoea and preterm labour. Prostaglandins are also involved in the regulation of uterine activity with different receptors mediating both stimulation and relaxation. We explored different aspects of synthesis, release and receptor pharmacology of vasopressin and oxytocin. We also tested a vasopressin and o

Popular Abstract in Swedish Jorden är ett ytterst komplext och dynamiskt system. Livet har format planeten och utvecklats i takt med förändrade livsvillkor. Ekosystemen kontrolleras i hög grad av klimatet. Snabbt förändrade villkor innebär betydande påfrestningar för åtskilliga arter och ekosystem, inklusive planetens mest dominerande art, människan. Avhandlingens huvudfokus är att undersöka samsThe Earth is a highly complex and dynamic system. Life has shaped the entire planet and evolved in response to living conditions. Ecosystems are heavily affected by climate. Rapidly changing conditions imply considerable stress on several species and ecosystems, as well as to the most dominant species on the planet. The main focus of this thesis is to investigate climate and anthropogenic interac

Immunoglobulins (Ig), particularly IgE, are believed to be crucially involved in the pathogenesis of asthma and, equally, in allergic models of the disease. To validate this paradigm we examined homozygous mutant C57BL/6 mice, which are B cell deficient, lacking all Ig. Mice were immunized intraperitoneally with 10 micrograms ovalbumin (OVA) plus alum, followed by daily (day 14-20) 30 min exposure

Popular Abstract in Swedish Sammanfattning I debatter och forskning om narkotikapolitik anges den svenska och nederländska modellen ofta som ett motsatspar. Såväl målet för, som utformningen av, narkotikapolitiken har framställts som radikalt olika. Detta synsätt kan sägas vara riktigt. Målet för den svenska narkotikapolitiken är att skapa ett narkotikafritt samhälle. Den nederländska strävar efteIn debates about the Swedish and Dutch drug policies are usually positioned as opposites. The goal for the Swedish drug policy is to create a 'drug-free society'; while in the Netherlands a harm reduction approach prevails. In this study a drug policy is considered a practice of formal social control that can develop differently depending on the contexts in which it emerged. The period studied sta

This dissertation presents the design and implementation of a new block diagram programming language, Bloqqi, for building control systems with focus on variability. The language has been developed in collaboration with industry with the goal of reducing engineering time and improving reuse of functionality.When building a control system for a plant, there are typically different variants of the s

A reliable assessment of the optical properties of atmospheric black carbon is of crucial importance for an accurate estimation of radiative forcing. In this study we investigated the spatio-temporal variability of the mass absorption cross-section (MAC) of atmospheric black carbon, defined as light absorption coefficient (σap) divided by elemental carbon mass concentration (mEC). σap and mEC have

Optical microscopy is a fundamental tool in a range of disciplines encompassed by the physical and biological sciences. At the dawn of this millennium, a break-through was made in optical microscopy where super-resolution methods emerged and declared imaging beyond the optical diffraction limit a possibility. Most of these methods are based on fluorescence detection of single molecules. These meth

Oceans dominate emissions of dimethyl sulfide (DMS), the major natural sulfur source. DMS is important for the formation of non-sea salt sulfate (nss-SO42−) aerosols and secondary particulate matter over oceans and thus, significantly influence global climate. The mechanism of DMS oxidation has accordingly been investigated in several different model studies in the past. However, these studies had

This study reports an aviary experiment aimed at determining what affects social dominance in the great tit (Parus major), especially why older birds (adults) in nature normally dominate younger ones (juveniles). When birds were matched with respect to age, prior residency determined dominance. Without a difference in prior residency older birds dominated younger ones. However, when juvenile birds

BACKGROUND: Many clinical trials have evaluated the benefit of long-term use of antiplatelet drugs in reducing the risk of clinical thrombotic events. Aspirin and ticlopidine have been shown to be effective, but both have potentially serious adverse effects. Clopidogrel, a new thienopyridine derivative similar to ticlopidine, is an inhibitor of platelet aggregation induced by adenosine diphosphate
