Popular Abstract in Swedish Begreppet social rörlese är ett centralt sociologiskt begrepp. Trots det finns det en rad olika sätt att definiera detta begrepp. Avhandlingen söker svara på frågan vad begreppet social rörelse "betyder". För att svara på den frågan utgår författaren från en arbetsdefinition och en rad dimensioner av begreppet. Via en läsning av begreppets teoretiska utveckling söker föThis thesis develops the concept formation of 'social movement'. The author stresses the importance of the inherent classical understanding of the concept as defining a collective actor involved in a struggle regarding main social and cultural trends in society. The concept of social movement is treated as having been an unclear concept. The author therefore formulates a working definition that al

Popular Abstract in Swedish Undersökningarna som presenteras i avhandlingen behandlar mätning av produkter från och händelser i förbränningsprocessen genom att använda laserbaserade mätmetoder. Ett antal olika körfall, som HCCI och partially premixed combustion (PPC), har undersökts. I de första mätningarna som presenteras jämförs uppmätta flödesfält i cylindern med resultat från CFD och blåsriggThe work presented in this thesis deals with measuring in-cylinder combustion species and events using different laser-based diagnostic methods. A variety of engine operating modes, like HCCI and partially premixed diesel combustion, have been investigated. In the very first measurements, in-cylinder flow-fields were compared to CFD and steady-state blow rig results. After that, the ignition and

This thesis deals with students' constructions of mathematical knowledge in the case of fractions from a radical constructivist perspective. Fractions are the first more abstracted mathematics met by students. Even if they have a rich experience of sharing and partitioning things in their everyday life dealing with fractions often give rise to difficulties in school. The thesis consists of two p

1. Geolocation by light allows for tracking animal movements, based on measurements of light intensity over time by a data-logging device (geolocator). Recent developments of ultra-light devices (<2 g) broadened the range of target species and boosted the number of studies using geolocators. However, an inherent problem of geolocators is that any factor or process that changes the natural light in

Very few principles have been unraveled that explain the relationship between soil properties and soil biota across large spatial scales and different land-use types. Here, we seek these general relationships using data from 52 differently managed grassland and forest soils in three study regions spanning a latitudinal gradient in Germany. We hypothesize that, after extraction of variation that is

Life on Earth was sharply disrupted 66 Ma ago as an asteroid hit the sea-floor in what is today Yucatan Peninsula, Mexico. Approximately 600 km(3) of sedimentary rock were vapourized, ejected into the atmosphere and subsequently deposited globally as an ejecta apron and fallout layer. Proximal ejecta deposits occur in Belize and southern Mexico where the so called Albion island spheroid bed is sup

Background. Although the clinical importance of demonstrating the presence of anti-glomerular basement membrane (anti-GBM) antibodies is well established, less is known concerning the clinical utility of measuring the levels of autoantibodies. Two conformational epitopes of anti-GBM antibodies have been defined at residues 17-31 and 127-141 of the alpha 3(IV)NC1 domain of type IV collagen [alpha 3

Background: The acceptable noise level (ANL) test is a method for quantifying the amount of background noise that subjects accept when listening to speech. Large variations in ANL have been seen between normal-hearing subjects and between studies of normal-hearing subjects, but few explanatory variables have been identified. Purpose: To explore a possible relationship between a Swedish version of

Popular Abstract in Swedish Två av de viktigaste polyaminerna påträffades redan i slutet av 1600-talet, som kristaller i tjursperma och har därför fått namnen spermin och spermidin. Dessa aminer bildas från en annan substans, putrescin, som först isolerades från ruttnande kött. Namnet putrescin kommer från engelskans putrefaction, som betyder förruttnelse. Polyaminer, som kemiskt sett är positivt The polyamines putrescine, spermidine and spermine are essential for cell growth and differentiation. The biosynthesis of polyamines are tightly regulated by feedback mechanisms involving two enzymes, namely ornithine decarboxylase (ODC) and S-adenosylmethionine decarboxylase (AdoMetDC). This thesis deals with the mechanisms behind the polyamine-mediated feedback control of these enzymes. The poly

Polymer dispersions are employed in a wide variety of applications as film formers. Especially in the coating-, paint-, pharmaceutical and hygiene industry polymer dispersions are to a large extent used as barriers, controlled-release agents and adhesives. Control and steering of the polymerization process has resulted in the production of core-shell structures with soft and hard (low glass transi

This dissertation has three cornerstones: * Haptics * Human-Computer Interaction (HCI) * Blind Users Haptics deals with controlling human movements and getting feedback through the sense of touch. A haptic interface transmits forces to a person’s hand or fingers in a way that mimics the sensation of touching real objects. Virtual haptic touch can be particularly useful for people with visual i

Popular Abstract in Swedish Deponeringsavgifterna för slam utgör en betydande och stadigt stigande andel av driftkostnaderna för de kommunala reningsverken runtom i landet, inom EU och i resten av världen. Kostnaderna uppstår i samband med att slammet komposteras, körs till deponi eller till förbränning. Dessutom har det under de gångna årtiondena skett en drastisk omvärdering av reningsverksslam The reduction of sludge volumes for disposal is a topic of high interest for wastewater treatment plants (WWTP) all over the world. Steadily increasing volumes for disposal create an economic, environmental, legislative and technological challenge. Researchers and process developers try to minimise the sludge during its genesis or in the downstream treatment. Due to rising costs and scarcity of fo

This thesis investigates the adsorption, decomposition and reactions of small molecules on flat, oxidised and vicinal surfaces of late transition metals. The main technique for these studies is high resolution core level spectroscopy (HRCLS). All the studies presented in the thesis are performed in Ultra High Vacuum (UHV). The articles can be divided into three groups. The first three articles dea

To elucidate the molecular requirements for cancer cell internalization of the extracellular cysteine protease inhibitor cystatin C, 12 variants of the protein were produced and used for uptake experiments in MCF-7 cells. Variants with alterations in the cysteine cathepsin binding region ((Δ1-10)-, K5A-, R8G-, (R8G,L9G,V10G)-, (R8G,L9G,V10G, W106G)-, and W106G-cystatin C) were internalized to a ve

Popular Abstract in Swedish Kunskapsarbete framställs ofta som något som präglas av dolskhet eller oklarhet: produkten som säljs är oklar, resultatet är oklart och även själva arbetsprocesserna framställs ofta som oklara. Detta påverkar i sin tur den styrning som man kan förvänta sig i kunskapsintensiv verksamhet: en styrning som ofta handlar om personalen mer än om arbetet. I denna studie problemKnowledge work is often portrayed as hidden or ambiguous: an ambiguous product is sold, ambiguous results are delivered, and work processes are ambiguous. This in turn affects the type of management expected in knowledge-intensive organisations, where emphasis is on managing people rather than work. In this study, the organisation of knowledge work is discussed and problematized through analysis o

Popular Abstract in Swedish I Big Bang, då vårt Universum skapades, bildades i princip endast de två lättaste grundämnena, väte och helium. Alla andra grundämnen har skapats, och skapas fortfarande, i olika typer av stjärnor under olika utvecklingsfaser. Detta betyder att precis alla atomer, förutom väte och helium, som bygger upp alla saker, växter, djur och människor i vår omgivning, har bildatsDisregarding the small primordial traces of the lightest elements, all metals have been formed in stellar processes, which means that the relative amount of metals in the Universe increases for every stellar generation. This build-up of elements is called chemical evolution and might be used both to constrain stellar models as well as understanding the formation and evolution of stellar population

The Sahel belt of Africa has been the focus of intensive scientific research since the 1960s, spurred on by the chronic vulnerability of its population to recurring drought and the threat of long-term land degradation. But satellite sensors have recently shown that much of the region has experienced significant increases in photosynthetic activity since the early 1980s, thus re-energizing long-sta

Long distance migration has evolved in many organisms moving through different media and using various modes of locomotion and transport. Migration continues to evolve or become suppressed as shown by ongoing dynamic and rapid changes of migration patterns. This great evolutionary flexibility may seem surprising for such a complex attribute as migration. Even if migration in most cases has evolved

Begreppsparet skön och regel speglar det i samhällsdebatten så omdiskuterade förhållandet mellan juridik och politik, där juridiken ofta anses ta större och större plats. Förvaltningsskönet, eller förvaltningens fria manöverutrymme, ses i många rättsordningar med en uttalad konstitutionell maktdelning, som något som hör förvaltningen och därmed politiken, med dess demokratiska mandat, till. SkönsmThe conceptual pair of discretion and rule reflects the much-debated relationship between law and politics in public discourse, where law is often seen as increasingly dominant. Administrative discretion, or the administration’s free scope of action, is in many legal systems with an explicit constitutional separation of powers, regarded as belonging to the administration, and thus to politics with
