A detailed flammability evaluation of different materials used in the nuclear power industry is presented as an example of how important are physical observation and detailed analysis in the interpretation of test data. The objective is to provide different criteria that could allow the use of standard test data in fire modeling. So far most fire test data has only been used as an element for rank
Authors: Therese Johansson, Moa Sundelin Title: “It’s just sex, man” - A qualitative study concerning personal experiences from those who sell sex through the Internet. [translated title] Supervisor: Lars B Ohlsson Advertisement on the Internet is getting more frequent and the prostitution business is no exception. Selling sex is a much-debated subject in Sweden and it is a very polarizing debate
The aim of our study is to understand how milk is represented online, more specifically on the Swedish web. We are interested in how information is being produced and distributed online, and also how networks of information are interconnected. We choose to examine milk because of the current controversies that have flourished online between a Swedish oat milk company and a Swedish milk organisatio
In developing countries across the world people are depending on rivers as a source of water for drinking, cooking and bathing. This is also the case in the Indonesian part of the island Borneo where this study was made. The largest river is the river Kapuas which, together with its tributaries, supplies the area with water. The hydrology of these rivers is changing and the quality of the water in
We report karyotypic features of 106 short-term cultured oral squamous cell carcinomas (SCC), 51 new and 55 previously reported cases, with clonal chromosome aberrations. The major cytogenetic findings were as follows: simple karyotypic changes were present in 38 cases (36%) and 68 tumors (64%) displayed complex karyotypes. The most common numerical changes were +7, +8, +9, +16, +18, +20, and -4,
OBJECTIVE: To identify perinatal factors associated with cerebral palsy (CP). METHODS: This was a case-control study based on the Swedish Medical Birth Registry and the Swedish Hospital Discharge Registry, including 2,303 infants born in Sweden 1984-1998 with a diagnosis of CP and 1.6 million infants without this diagnosis. Odds ratios (ORs) with 95% confidence intervals (Cis) were calculated. RES
Electronic and structural properties of Sb-induced GaAs(100)(2x4) and (2x8) surfaces are studied by means of core-level and valence-band photoelectron spectroscopy utilizing synchrotron radiation and scanning tunneling microscopy. Combining these results and showing good consistency among them, we demonstrate that the Sb/GaAs(100)(2x4) surface is well compatible with the delta structural model, wh
BACKGROUND AND PURPOSE: To determine how a recently proposed clinical stroke subclassification corresponds to specific findings on computed tomography (CT) and magnetic resonance imaging (MRI) of the brain. METHODS: Two hundred twenty-eight patients with first-ever stroke were divided into four clinical subgroups: (1) total anterior circulation syndrome: both cortical and subcortical symptoms from
Popular Abstract in Swedish Variabilitet i ett läkemedels farmakokinetiska (hur ett läkemedel omsätts i kroppen) och farmakodynamiska (vilken effekt ett läkemedel har) egenskaper kan resultera i att olika individer som erhållit samma dos av ett läkemedel får olika effekter av läkemedel. Biverkningar eller utebliven effekt kan innebära allvarliga konsekvenser för den enskilda individen. VariabiliteVariability in pharmacokinetic and pharmacodynamic parameters between individuals can be due to intrinsic and extrinsic factors. In this thesis three different areas regarding sources of variability have been investigated. 1. Formulation properties as an extrinsic source of variability. Lipophilic substances often have poor oral bioavailability and high inter- and intraindividual variability. High
In order to elucidate the influence of nicotine smoking on bone mass in elderly women, bone mass was cross-sectionally assessed by dual energy X-ray absorptiometry (DXA) in total body, hip and lumbar spine, as well as with ultrasound of calcaneus and phalanges of the hand. Subjects were 1,042, 75-year old women, recruited on a population basis (Osteoporosis Prospective Risk Assessment (OPRA) study
CONTEXT: Carpal tunnel syndrome (CTS) is a cause of pain, numbness, and tingling in the hands and is an important cause of work disability. Although high prevalence rates of CTS in certain occupations have been reported, little is known about its prevalence in the general population. OBJECTIVE: To estimate the prevalence of CTS in a general population. DESIGN: General health mail survey sent in Fe
We have previously shown that porcine aortic endothelial cells expressing the Y934F platelet-derived growth factor (PDGF) beta-receptor mutant respond to PDGF-BB in a chemotaxis assay at about 100-fold lower concentration than do wild-type PDGF beta-receptor-expressing cells (Hansen, K., Johnell, M., Siegbahn, A. , Rorsman, C., Engstrom, U., Wernstedt, C., Heldin, C.-H., and Ronnstrand, L. (1996)
BACKGROUND: Some autoimmune disorders have been linked to venous thromboembolism. We examined whether there is an association between autoimmune disorders and risk of pulmonary embolism. METHODS: We followed up all individuals in Sweden without previous hospital admission for venous thromboembolism and with a primary or secondary diagnosis of an autoimmune disorder between Jan 1, 1964, and Dec 31,
There is little epidemiological data on heart failure (HF) in the younger age groups dominating clinical HF trials. We assessed gender-specific long-term HF incidence and mortality in an urban community-based sample of middle-aged subjects. Between 1974 and 1992, 33,342 HF-free subjects (10,900 [32.7%] women, mean age 45.7 +/- 7.4 years) were included in the Malmö Preventive Project, on average 21
Growth anomaly of trees in some regions was detected under current episode of rapid warming. Thisraises a dilemma for temperature reconstructions by using tree-ring width which is believed to be themost important proxy on inter-annual temperature reconstruction during the past millenniums. Here weemployed the tree-ring d13C to reconstruct temperature variations for exploring their potential oncapt
BACKGROUND: Multiparametric magnetic resonance imaging (MRI), with or without targeted biopsy, is an alternative to standard transrectal ultrasonography-guided biopsy for prostate-cancer detection in men with a raised prostate-specific antigen level who have not undergone biopsy. However, comparative evidence is limited. METHODS: In a multicenter, randomized, noninferiority trial, we assigned men
Background Integrating mental health with general medical care can increase access to mental health services, but requires helping generalists acquire a range of unfamiliar knowledge and master potentially complex diagnostic and treatment processes.Method We describe a model for integrating complex specialty care with generalist/primary care, using as an illustration the integration of mental heal
Ever since its introduction 40 years ago l-3,4-dihydroxyphenylalanine (l-DOPA) therapy has retained its role as the leading standard medication for patients with Parkinson's disease. With time, however, the shortcomings of oral l-DOPA treatment have become apparent, particularly the motor fluctuations and troublesome dyskinetic side effects. These side effects, which are caused by the excessive sw
Background: Lung cancer patients have a risk of recurrence even after curatively intended surgery. Cell-free circulating tumor DNA (ctDNA) and circulating tumor marker measurements are easily accessible through peripheral blood and could potentially identify patients with worse prognosis. The aim of this study was to examine ctDNA in pre-operative plasma and the role of tumor markers in pre-operat
