In this paper, return migration from Sweden to three sources of refugee immigration is analysed, with a focus on the effect of political change in 1990. Chilean immigrants reacted more strongly to political liberalization in the home country than Polish immigrants did, primarily due to more favourable economic circumstances in Chile compared to Poland in the 1990s. In fact, the increase in Polish
Expression of the human cysteine proteinase inhibitor, cystatin C (CysC) in the cytoplasm of Escherichia coli was studied using a cDNA fragment encoding the cysteine proteinase inhibitor controlled by the phage λ pImage /cI857 system. The yield of CysC was low, probably due to proteolytic degradation. By fusing the cysC cDNA to a DNA fragment encoding the signal peptide of the E. coli outer membra
PURPOSE: The reduced size of abdominal aortic aneurysms (AAAs) after endovascular repair suggests lowered intraaneurysmal pressure. In the presence of endoleaks, the size is not decreased. Although postoperative intraaneurysmal pressure is difficult to record, the pulsatile wall motion (PWM) of aneurysms can be measured noninvasively. The aim of this study was to assess the PWM of AAAs before and

The processes of intraepithelial migration, intraluminal seeding, and field cancerization as models for initiation, spread, and recurrences of urothelial cell carcinoma (UCC) are reviewed in light of recent molecular investigations. The accumulated molecular data on synchronous and metachronous tumors indicate that the majority of recurrent and multiple tumors are monoclonal. Molecular data has al
The focus of this paper is to derive the symbol error probability (SEP) of a Rake receiver with a limited number of fingers that track the strongest multipath components in a frequency-selective Rayleigh fading channel. We develop an analytical framework that allows the computation of the SEP for nonuniform power dispersion profiles (PDPs) and spreading bandwidth. By transforming the physical Rake
Popular Abstract in Swedish Hur kan man förklara vardagligt tänkande med de kognitiva teorier som finns tillhands idag? Ofta är dessa teorier konstruerade för att kunna förutsäga beteende under kontrollerade omständigheter, som i ett laboratorium. Å andra sidan är det snarare flexibilitet och improvisation som kännetecknar det vardagliga tänkandet. I avhandlingen försöker jag ta reda pa vad man måHow well can we explain natural occurrences of cognitive behaviours given the theoretical frameworks available to us today? The thesis explores what has to be assumed in cognitive theory in order to provide such an explanation, in contrast to being able to predict behaviour under controlled circumstances. The behaviours considered are all of the type described as involving higher level cognition
An appropriate animal model is essential to study Helicobacter pylori infection. The aim of this study was to investigate if H. pylori can colonise the guinea-pig stomach and whether the infection causes gastritis and a serological response similar to that observed in man. Guinea-pigs were infected either with fresh H. pylori isolates from human gastric biopsies or with a guinea-pig passaged strai
1 Organ culture has been shown to upregulate both endothelin (ET) and 5-hydroxytryptamine 1B/1D (5-HT(1B/1D)) receptors in rat cerebral arteries. The purpose of the present study was to investigate the involvement of protein kinases, especially protein kinases C (PKC) and A (PKA) in this process. 2 The effect of inhibiting protein kinases during organ culture with staurosporine (unspecific protein
A common problem in particle physics is the requirement to reproduce comparisons between data and theory when the theory is a (general purpose) Monte Carlo simulation and the data are measurements of final state observables in high energy collisions. The complexity of the experiments, the obervables and the models all contribute to making this a highly non-trivial task. We describe an existing lib
Cocaine- and amphetamine-regulated transcript-derived peptides (CARTp) and corticotropin-releasing factor (CRF) alter feeding and gastrointestinal function after central administration, and the gastric inhibitory effects are mediated through CRF. We hypothesized that dorsal hindbrain effects of CARTp on gastric emptying are mediated by the vagus nerve and that the dorsal vagal complex (DVC) is a s
Several studies have presented data on the efficacy and tolerability of trastuzumab within clinical trials. As a minority of patients is included in these trials, we undertook this retrospective study to describe trastuzumab therapy in clinical routine and its tolerability. We reviewed the medical records of the first 48 patients in Sweden who received treatment with trastuzumab on a named patient
In this paper, the formaldehyde emissions from three different types of homogenous charge compression ignition (HCCI) engines are quantified for a range of fuels by means of Fourier Transform Infra Red (FTIR) spectroscopic analysis. The engines types are differentiated in the way the charge is prepared. The characterized engines are; the conventional port fuel injected one, a type that traps resid
Popular Abstract in Swedish ”Vardagliga problem hos män med prostata cancer. Upplevelser av problem med att kasta vatten, bära kateter och problem i sexuallivet”. Avhandlingens övergripande syfte var att undersöka förekomsten av vardagliga problem hos män med prostatacancer, problemens relation till livskvalitet, till känsla av sammanhang och relationen mellan dessa faktorer, samt att jämföra medThe aim was to investigate the presence of everyday problems in men with prostate cancer, their relation to health-related quality of life, HRQOL, and sense of coherence, SOC, and to compare with men with benign prostatic hyperplasia, BPH, and a sample from the general population. The aim also was to investigate what nursing care needs there were in men with prostate cancer and how these were met
Measurements of the stoichiometry of silicon nitride films as a function of the number of incident ions using heavy ion elastic recoil detection (ERD) show that beam-induced nitrogen depletion depends on the projectile species. the beam energy, and the initial stoichiometry. A threshold stoichiometry exists in the range 1.3 > N/Si greater than or equal to 1, below which the films are stable agains
