In this paper, two approaches to data mining of time series have been tested and compared. Both methods are based on the wavelet decomposition of data series and allow the localization of important characteristics of a time series in both the time and frequency domain. The first method is a common method based on the analysis of wavelet power spectra. The second approach is new to the applied fiel

Popular Abstract in Swedish Hematopoes är den process under vilken alla röda och vita blodceller i kroppen bildas. Denna process sker kontinuerligt i benmärgen och förser kroppen med blodceller under hela livet. I benmärgen finns en viss typ av omogna celler sk stamceller som alla olika typer av blodceller bildas ifrån. Genom att stamceller gradvis mognar så bildas mogna blodceller som transporterThe Wilms tumor gene 1 (WT1) encodes a zinc-finger containing transcription factor which is highly expressed in immature hematopoietic progenitor cells. A high expression of WT1 and the presence of somatic mutations in acute leukemia indicate a role for WT1 in the pathogenesis of leukemia. The ojective of this thesis was to investigate the role of WT1 during human hematopoiesis and leukemia. To ga

Glucagon- like peptide-1 ( GLP-1) plays a significant role in glucose homeostasis through its incretin effect on insulin secretion. However, GLP-1 also exhibits extrapancreatic actions, and in particular its possible influences on insulin sensitivity are controversial. To study the dynamic action of GLP-1 on insulin sensitivity, we applied advanced statistical modeling methods to study glucose dis

Between 20 and 30 per cent of all breast cancers show an overexpression of the growth factor HER2 and this implies a worse prognosis. Metastasising breast cancer that overexpress HER2 can effectively be treated with trastuzumab (Herceptin). In order to determine whether this treatment is indicated, HER2 expression must be quantified with immunohistochemical or molecular biological methods. Several

The ability to perceive and express prosodic qualities of speech was tested in 21 patients with a single focal ischaemic disturbance of the right hemisphere, 14 patients having an infarct and 7 transient ischaemic attacks, and in 21 age-matched normal controls. All patients were predominantly right-handed. None showed signs of aphasia. Pure tone audiometry showed acceptable hearing for speech. The

Background. Goodpasture's disease (GP) is a rare but severe disease characterized by anti-glomerular basement membrane antibodies, rapidly progressive glomerulonephritis and lung haemorrhage. The autoantibodies are restricted to a narrow epitope region on the NC1 domain of the alpha3 chain of type IV collagen. GP is strongly associated with major histocompatibility complex (MHC) allele HLA DRB1-15

Milk fat globule membrane (MFGM) lipids have been studied in the presence and absence of proteins -lactoglobulin and -casein. The aim of this study was to relate the self-assembly structure, e.g. vesicles, formed in aqueous dispersions of MFGM lipids to the lipid composition, electrolyte composition as well as the effect of added milk proteins, i.e. -lactoglobulin and -casein. For this purpose, ve

Background and Purpose - Stroke induced by middle cerebral artery occlusion (MCAO) causes long-term formation of new striatal neurons from stem/progenitor cells in the subventricular zone (SVZ). We explored whether MCAO leads to hypoxia, changes in vessel density, and angiogenesis in the ipsilateral SVZ and adjacent striatum, and determined the relation between the migrating neuroblasts and the va

Self-levelling flooring compounds (SLC) are used to level substrates (mainly concrete slabs) before applying final floor coverings. Although it is an extensively used product, only limited research has so far been published concerning their moisture properties. This report focuses on moisture properties of SLC and describes methods for determining them. Moisture properties of materials are importa

The interaction behavior of DNA with different types of hydroxylated cationic surfactants has been studied. Attention was directed to how the introduction of hydroxyl substituents at the headgroup of the cationic surfactants affects the compaction of DNA. The DNA-cationic surfactant interaction was investigated at different charge ratios by several methods like UV melting, ethidium bromide exclusi

The basis of this paper is a comparative study, on the one hand of the frequency of saints' names among the women in medieval Denmark, and on the other of the occurrence of pictures of female saints in the same region. As to certain names, e g Catherine, Barbara and Anne, there is a correspondence of frequency and time, which suggests a deliberate popularization of the saints in question. Othr cas

The most important issue in this dissertation will be a discussion concerning metal age flint use in Scania. Since flint tools from the Bronze and Iron Ages and Medieval times have rarely been examined, there are few general guidelines in typology or morphology. It is quite clear that conversions of existing Stone Age typological schemes are unsuitable when one intends to study the often simple an

We investigate the effects of metallicity on the broad-band photometric colors of late-type giants, and make a comparison of synthetic colors with observed photometric properties of late-type giants over a wide range of effective temperatures (T-eff = 3500- 4800K) and gravities (log g = 0.0-2.5), at [M/H] = -1.0 and -2.0. The influence of metallicity on the synthetic photometric colors is small at
