Popular Abstract in Swedish Under fosterutvecklingen är det viktigt att alla kroppens celltyper kommer till rätt plats vid rätt tidpunkt. Det är också viktigt att cellerna mognar och delar sig under kontrollerade former. Då dessa processer inte fungerar, kan missbildningar eller cancer uppstå. Redan på embryonalt stadium börjar nervsystemet ta form. En del av nervsystemet kallas det autonoma elleNeuroblastoma is a tumor of the sympathetic nervous system, and arises during early childhood. The tumor is highly heterogeneous and evidence, such as expression of genes normally only expressed during embryonic and fetal stages, suggests that the tumor is of embryonic origin and that the tumor arises as a consequence of perturbed differentiation during the development of the sympathetic nervous s

The Swedish Higher Education Ordinance states1 in Chapter 8, section 1 (Svensk Förfat- tningssamling [SFS] 1993:100) that disciplinary action can be taken against a student who “at- tempt to deceive during examinations or when academic work is otherwise assessed”. Suspicion of such behaviour is to be reported to the disciplinary board, which in turn has to establish the students intent. The main f

Three nuclei with mass number A=61 have been studied using four fusion-evaporation experiments carried out at the Oak Ridge, Argonne and Lawrence Berkeley National Laboratories. Normally deformed states in 61Ga were for the first time ever explored and in addition the experimental knowledge of the mirror nucleus 61Zn was extended. The two nuclei together provide the possibility to explore mirror

The subjects of this thesis are (as indicated by the title) truth, grounding and dependence. The thesis consists of an introduction and five free-standing essays. The purpose of the introduction is not merely to summarize the papers, but to provide a general background to the discussions in the essays. The introduction is divided into four chapters, each of which splits into a number of sections a

Adaptive predistortion is one of the most promising methods to linearize RF power amplifiers (PAs). Its linearity performance is, however, limited by various memory effects existing in the system. In this paper, we study the effects of anti-aliasing filters in the feedback path of adaptive predistortion. Different filter approximations are examined with a class AB power amplifier by means of simul

Over the last decades or so, artificial neural networks (ANNs) have become one of the most promising tools for modelling hydrological processes such as rainfall-runoff processes. In most studies, ANNs have been demonstrated to show superior result compared to the traditional modelling approaches. They are able to map underlying relationships between input and output data without detailed knowledge

Popular Abstract in Swedish Många framsteg har gjorts inom bioteknik de senaste decennierna. Idag kan vissa sjukdomar fastställas redan på DNA-nivå och viktiga läkemedel samt tvättmedelskomponenter tillverkas industriellt med hjälp av gentekniska tekniker. Kostnaden för de gentekniska produkterna ligger till stor del i själva uppreningsprocessen. Forskningen i denna avhandling har gjorts med avsikThis thesis describes the possibility of using hydrophobic peptide tags as tools for bioseparation and for the investigation of recombinant proteins. The hydrophobicity of a protein can easily be changed by minor modifications, such as fusions of tyrosine-containing peptides. The fusion tags may also increase both stability and expression of the fusion protein. Furthermore, a protein library with

Hur går det till när en sekulär demokratisk stat, som den svenska, använder religion för samhällsekonomiska syften? En uttalad samhällsstrategi för att styra arbetsmarknaden är att främja jämställda, toleranta och demokratiska värderingar (den s.k. värdegrunden), eftersom dessa tänks bidra till att fler kvinnor och invandrare kommer ut på arbetsmarknaden. Dessa värderingar ges indirekt en religiös
