Popular Abstract in Swedish Avhandlingen visar två olika vägar för att skapa brukarinflytande, den kollektiv- och den individinriktade vägen. Den kollektiva inriktningen innebär att medborgarna endast kan utöva inflytande via folkvalda företrädare, medan den individinriktade vägen ger möjlighet att samverka direkt med politiker och tjänstemän i den kommunala organisationen. Två olika teorier har aThe dissertation shows two different means or directions for creating civic participation: the collective and the individual way. The collective way is characterized by the citizen's ability to participate only through elected representatives while the individual way makes it possible for inhabitants to participate face to face with politicians and local civil servants. Two different theories hav
Popular Abstract in Swedish Denna avhandling behandlar den process där man beräknar undervattensströmmar från ljud som reflekteras från en utsänd ljudpuls, precis som när en fladdermus bedömer omgivningen genom att lyssna på ekot. En ton skickas ut under en kort tid, och det Dopplerskift som uppkommer från rörliga föremål i vattnet kan sedan omsättas till vattenhastiget eller ström. Föremål som röThis thesis deals with the process of estimating underwater current from the backscattering signal transmitted from an ultrasonic transducer. The narrowband sinusoidal burst signal is Doppler-shifted due to the current, and this information is converted into current. The traditional mathematical model for this Doppler process is based on the assumption that the backscattering time signal is Gaussi
Försoning är ett centralt tema i den kristna kyrkan. Denna studie indikerar en diskrepans mellan den teologiska förståelsen av försoning och den praxis som utövas under och efter en konflikt orsakad av olika uppfattningar om församlingens kultur eller identitet, särskilt i relation till vitaliseringsrörelser – förnyelse.I denna studie har etthundra konflikter eller potentiella konflikter som uppstReconciliation is a central theme in the Christian church. This study proceeds from a discrepancy between the theological understanding of reconciliation on the one hand and praxis in dealing with conflicts caused by different opinions about the culture or identity of the church on the other, especially in connection with vitalization (or renewal) movements.In this study, one hundred conflicts or
Se-methyl L-selenocysteine (MeSeCys) is one of the major organic selenium compounds acquired from the diet by human beings. It has been shown to have anticancer activity and cancer prevention functions. However, its antioxidant activity, largely related to its biological function, has not been well characterized so far. We here report a stopped-flow kinetic study of the reduction of the Pt(IV) antSe-methyl L-selenocysteine (MeSeCys) is one of the major organic selenium compounds acquired from the diet by human beings.

Popular Abstract in Swedish Avhandlingen behandlar kapacitet i cirkulationsplatser. Kapaciteten för ett körfält i en tillfart kan beräknas med teorin för kritiska tidsavstånd. Denna bygger på interaktioner mellan fordon med företräde (överordnade fordon) och fordon som skall lämna företräde (underordnade fordon). Det kritiska tidsavståndet är det minsta tidsavstånd mellan två överordnade fordon soProblem: The thesis deals with the capacity of two-lane roundabouts and with vehicle-vehicle interactions there. Method: The interactions and the corresponding capacity are modelled by gap-acceptance theory. Various components of this theory are discussed, models for headways in the multi-lane case and for the estimation of critical gaps for the two major streams being developed and being applied
Popular Abstract in Swedish Denna avhandling behandlar storlekskarakterisering av stora molekyler (polymerer) med en ny teknik, nämligen flödesfältflödesfraktionering (flödesFFF). Det aktuella storleksområdet som studerats i avhandlingen är intervallet mellan några få nanometer(nm) upp till en halv mikrometer (um). Storleksbestämningen med flödesFFF baseras på en separation av material med olika dSize, as expressed by molar mass, radius of gyration or hydrodynamic radius, for example, is a fundamental parameter of polymers in solution. Thus, there is a strong need for the characterisation of both the size and shape of polymers, particularly of those utilised in various industrial applications. In this thesis, a relatively novel technique, asymmetrical flow field-flow fractionation (flow FF
Popular Abstract in Swedish Inom analytisk kemi används en rad metoder för att erhålla separation mellan de ämnen man vill studera. Detta är ofta nödvändigt om man vill ta reda på specifika egenskaper i ett biologiskt prov. Naturen har utvecklat sofistikerade verktyg t.ex. antikroppar som även kan användas för att separera ett specifikt ämne. Inom mitt doktorsarbete har antikroppar fyllt en viktigThe use of microdialysis sampling and flow immunochemical detection as well as MALDI-TOF MS for peptide and protein analysis is described. Sampling of peptides and smaller proteins was investigated with different membranes. Cyclodextrines additives and an on-line push-pull microdialysis sampling method was used with the result of a higher sampling efficiency compared to conventional microdialysis
Popular Abstract in Swedish Insekter kommunicerar med dofter. De artspecifika kemiska substanser som används mellan individer kallas feromoner. Hos sädesbroddflyet, Agrotis segetum, producerar honan en "parfym", ett sexualferomon som består av flera komponenter, för att locka till sig en hane. På hanens antenner finns lukthår med särskilda motagare, receptorer, som används för att detektera honansA number of analogues of (Z)-5-decenyl acetate (1), a pheromone component of the turnip moth, Agrotis segetum, have been synthesised and tested by using single-cell electrophysiology, in order to investigate the relationships between structure and activity, and to elucidate the interactions between 1 and its receptor. Molecular mechanics and ab initio quantum mechanical calculations have been used

Att ersätta ändliga resurser med förnybara alternativ är en av mänsklighetens största utmaningar i modern tid. Utsläpp av växthusgaser orsakade av mänsklig civilisation behöver minska, och nya forskningsbaserade lösningar är nödvändiga för att åstadkomma långsiktigt hållbar tillväxt. I denna omställning kan biomassa från växter spela en viktig roll. Växtbiomassa består mestadels av socker som sittβ-Mannanases are a major type of enzyme involved in the hydrolysis and modification of β-mannans, a hemicellulose present in high amounts in e.g. softwoods such as spruce. The β-mannanases studied in this thesis belong to glycoside hydrolase (GH) families GH5 and GH26. In addition to hydrolysis, some β-mannanases can also catalyze transglycosylation whereby another molecule (acceptor) is transferr
High-content real-time imaging of hormone secretion in tissues or cell populations is a challenging task, which is unlikely to be resolved directly, despite immense translational value. We approach this problem indirectly, using compensatory endocytosis, a process that closely follows exocytosis in the cell, as a surrogate read-out for secretion. The tissue is immobilized in an open-air perifusion
It is well documented that Chinese parents invest enormous amounts of time, resources and emotions in their children’s education, as if a life worthwhile is a life where education and self-cultivation is at the fore. Taking part in and excelling in educational activities is a moral imperative that marks childhood, whereby achieving in school is not only an act of filial piety, but also a patriotic
Ambitiösa ideal om tvärvetenskap är välkänt svåra att omsätta i praktiken, delvis beroende på att de motarbetas av hur många universitet är strukturerade. Detta är ett problem för doktorander i tvärvetenskapliga projekt såväl som för deras handledare. Tvärvetenskapliga doktorander har precis som alla doktorander ett forskningsämne i vilket de förväntas utvecklas till självständiga forskare men ockAmbitious ideals about interdisciplinarity are notoriously difficult to put into practice, partly because they are counteracted by how many universities are organised. This is a problem for doctoral students in interdisciplinary projects as well as for their supervisors. Interdisciplinary doctoral students, like all doctoral students, have a research subject in which they are expected to develop i
We introduce a family of stochastic optimization methods based on the Runge–Kutta–Chebyshev (RKC) schemes. The RKC methods are explicit methods originally designed for solving stiff ordinary differential equations by ensuring that their stability regions are of maximal size. In the optimization context, this allows for larger step sizes (learning rates) and better robustness compared to e.g. the p
When an internet user opens a web page containing an advertising slot, how is it determined which ad is shown? Today, the most common software-based approach to trading advertising slots is real time bidding: as soon as the user begins to load the web page, an auction for the slot is held in real time, and the highest bidder gets to display their advertisement of choice. Auction bidding is perform
Criminal groups are a debated social problem in Sweden the past years. The main purpose of this study was to investigate and analyze the work of professionals with criminals in defector support programs. Furthermore, the study examines professionals’ experiences of central factors in defectors leaving criminal groups. The study used a qualitative method in the form of semi-structured interviews wi
