Energy use and supply are evident issues to consider for a sustainable development, where the economic, social and environmental aspects are all important. In large grid-bound systems, the supply of energy is usually a rather invisible activity and the contacts between household custo-mers and utilities are sometimes only repre-sented through the energy bill. In this thesis, three particular field
The importance of the ability to use bipedal stance and gait in everyday life cannot be underestimated. Bipedal stance is learned during childhood and constantly adapted to changing circumstances throughout life. Failure to attain and maintain the control of upright posture can have catastrophic consequences. Postural competence needs to be recovered in a multitude of illness, in developmental dis
Popular Abstract in Swedish Det finns två etablerade sätt att beskriva zigenarnas historia i Sverige. Historien talar antingen om hur illa myndigheterna burit sig åt mot zigenare, eller så berättar historien om zigenarnas självvalda isolering. Gemensamt för beskrivningarna är påståendet att zigenare alltid varit desamma och uppvisar ett likartat levnadssätt genom historien. I denna avhandling studThis thesis analyses Swedish gypsy policy between 1880 and 1970, as part of a larger sociopolitical project undertaken by the Swedish authorities to promote social order and stability. During this period, the treatment of marginalized groups was shaped by the same visions and objectives as for the population as a whole. Gypsies in Sweden have been subject to the same regulations for as other poor
All hematopoietic cells originate from hematopoietic stem cells (HSC) residing in the BM. The process of differentiation, through which HSCs generate progenitors and subsequently mature blood cells has been extensively studied but many of the regulatory mechanisms involved remains elusive. The classical model for hematopoiesis has been established based on the identification of common myeloid prec
In hydrological models for water resources management and planning, the model output or design quantities are functions of the input data and a number of parameters that are essentially stochastic processes or random variables. The task of uncertainty analysis is to estimate the uncertainty characteristics of the model output in terms of the uncertainties in the input, model parameters and initial

In the process the mechanism of load transfer between units and mortar joints is described. The influence of cohesion between units and mortar joints, unit and joint geometry and ex
Collagen-induced arthritis (CIA) is one of the most commonly used animal models for Rheumatoid arthritis (RA). CIA is induced in susceptible mouse strains after immunization with heterologous type II collagen (CII). In mice of the H-2q haplotype rat CII (rCII) is used whereas in mice of the H-2r haplotype bovine CII is utilized. The broad objective of this thesis was to gain an understanding of th
Popular Abstract in Swedish Den s.k. "uncertain dichotomous choice" modellen används för att beskriva gruppbeslut. Modellen består av två komponenter: gruppstruktur och röstsystem. Gruppen utgörs av ett antal personer med ett gemensamt mål. Medlemmarnas uppgift är att välja ett av de två givna alternativen, av vilka det ena är korrekt. Dessa två symmetriska alternativ antas så utformade att det inA probabilistic framework used in studying collective decision making is the uncertain dichotomous choice model. The model is essentially characterized by two components: the organizational structure and the voting process. By organizational structure, we refer to a group composed of members with common objectives and who are tasked to choose one of the two given alternatives, one of which is assu
The East Asian monsoon has a strong seasonal effect on the rainfall regime of Eastern China. In order to mitigate floods and conserve the water for use throughout the year, dams and other hydro-structures are built. The design of the structures requires knowledge of the rainfall characteristics that influence the inflow to them. In this thesis, the properties of heavy rainfall in a 73 000 km2 area
The main purpose of the pursued research is to increase knowledge of the effects of knots in structural timber so that characteristics of weaker timber may be determined and applied to improve current grading techniques. In the process, a three-dimensional fiber paradigm was established, which describes variations of local principle material axes in timber containing knots. The adaptability of the
Popular Abstract in Swedish För att kunna simulera de fysikaliska fenomen som pågår i förbränning, krävs även en beskrivning av den kinetik som ingår i förbränningsprocessen. För detta ändamål utvecklas kinetiska modeller. En kinetisk modell är en lista med kemiska reaktioner och reaktionshastighetsparametrar. Modellernas tillämpningsområde begränsas av de valideringsfall och de fysikaliska parameThe simulation of physical phenomena occurring in chemical reactors requires the description of the kinetics involved in the underlying combustion process. Kinetic models are developed for this purpose. A software package, BlueBellMouse, has been developed to facilitate a deeper automatization and ease of simulation, reduction and optimization of kinetic models. A kinetic model is made of a list o
BACKGROUND: In the prostate, the importance of sex hormones for its normal development and function is well known. However, it has been proposed that various neuroendocrine (NE) hormones and growth factors may be involved in the pathogenesis of prostatic carcinoma (CaP). Neuroendocrine differentiation appears to be associated with tumour progression and the androgen-independent state, for which th
Popular Abstract in Swedish Tidigare trodde man att den vuxna hjärnan inte hade någon förmåga att nybilda nervceller. Detta skulle innebära att nervceller aldrig blev ersatta om de skadades eller dog. Nu vet man däremot att den vuxna hjärnan fortfarande producerar nya nervceller från särskilda moderceller, s.k. stamceller, belägna i åtminstone två områden i hjärnan: subgranulära zonen i hippocamThe adult brain constantly produces new neurons from endogenous neural progenitor cells located in at least two regions, the subgranular zone (SGZ) in dentate gyrus of the hippocampus, and the subventricular zone (SVZ). Major efforts are underway to discover the functional significance of new neurons in the adult brain. Several studies have indicated a relationship exists between newborn hippoca
Popular Abstract in Swedish Avhandlingen innehåller tre empiriska studier som analyserar hur livsmedelsmarknaden påverkas av åtgärder för att fördjupa den europeiska ekonomiska integrationen. Fokus är på det svenska EU-medlemskap och det kontinuerliga arbetet med att harmonisera livsmedelslagstiftningen. Det senare har stor relevans för livsmedelsmarknaden eftersom det har funnits och fortfarande This thesis consists of three papers, all of which deal with the effects of deepening European integration on the food and beverage industry and market. The focus is on the period after Swedish EU membership in 1995. The last two papers use firm data and focus on the Swedish food and beverage industry, an industry which is an interesting case study as it was considered to be protected from foreign

I ett samhälle där bilismen ökar blir en mer hållbar bilism allt viktigare. Sverige har satt upp som mål att ha en fossiloberoende fordonsflotta till 2030 och en helt fossilfri fordonsflotta till 2050. För att kunna uppnå detta spelar elbilen en viktig roll. Genom intervjuer med olika aktörer på den svenska marknaden visas i detta examensarbete att en stor tilltro sätts till elbilen, vid sidan av In a society with growing car mobility, sustainable motorism becomes increasingly important. Sweden has set targets of having a fossil fuel independent vehicle fleet by 2030 and a fossil free vehicle fleet by 2050.In order to reach these targets the electric car plays an important role. Through interviews with different actors on the Swedish market, this thesis shows that much confidence is put in
Three-dimensional (3D) models are widely used within the geosciences to provide scientists with conceptual and quantitative models of the earth’s subsurface. As a result, 3D geologic modelling is a growing field, such that scientific research often cannot keep up with technical advancements. Literature often shows conflicting results with respect to which interpolation algorithms produce the best
