Intumescent coating is an important fire protection method for steel structures. Traditionally its fire properties have been evaluated by performing furnace tests using a standardized test procedure and following a standardized time-temperature curve. This procedure is restrictive in performance based fire safety engineering design since it limits the fire condition to the standard one only. In th
OBJECTIVES: To determine the ability of transvaginal ultrasound, with or without saline infusion, to detect focally growing lesions in the uterine cavity in women with postmenopausal bleeding and endometrium > 5 mm, and to determine the accuracy of conventional ultrasound, saline contrast sonohysterography and diagnostic hysteroscopy under general anesthesia to diagnose endometrial polyps, submuco
A large pulse of atmospheric Cl-36 generated by a limited number of nuclear tests peaked in the late 1950s to early 1960s. The corresponding enhanced Cl-36 deposition is seen in various glaciological archives in the Northern Hemisphere. The profile of the bomb spike recorded in firn layers at Vostok Station, central East Antarctica. has been measured by employing accelerator mass spectrometry (AMS
Purpose. To define the association between venous volume as measured with air-plethysmography and the duplex ultrasound measured diameter of incompetent perforator of the lower limb. Patients and methods. Thirty-six patients with chronic venous disease were investigated with air-plethysmography and duplex ultrasound. Venous volume and venous filling time was measured. Venous filling index was calc
Popular Abstract in Swedish Avhandlingen behandlar kapacitet i cirkulationsplatser. Kapaciteten för ett körfält i en tillfart kan beräknas med teorin för kritiska tidsavstånd. Denna bygger på interaktioner mellan fordon med företräde (överordnade fordon) och fordon som skall lämna företräde (underordnade fordon). Det kritiska tidsavståndet är det minsta tidsavstånd mellan två överordnade fordon soProblem: The thesis deals with the capacity of two-lane roundabouts and with vehicle-vehicle interactions there. Method: The interactions and the corresponding capacity are modelled by gap-acceptance theory. Various components of this theory are discussed, models for headways in the multi-lane case and for the estimation of critical gaps for the two major streams being developed and being applied
Popular Abstract in Swedish Förbättrad patientsäkerhet och omvårdnad av patienter med höftraktur Intervention granskad i det nationella kvalitetsregistret RIKSHÖFT Varje år drabbas ca 18 000 personer i Sverige av höftfraktur efter fall. Höftfraktur är ett samlingsnamn för två frakturtyper i den övre delen av lårbenet. Den ena frakturtypen är lokaliserad till lårbenshalsen (cervikal fraktur) och dAim: Hip fractures are common and costly. The overall aim of this thesis was to explore how different clinical pathways influence safety and quality of care among patients with a hip fracture and to test the usefulness of the national quality register RIKSHÖFT as a working tool. The aim in paper I was to improve the outcome of patients with a hip fracture through optimized preoperative pain relief
S-phase fraction (SPF), estimated in the flow cytometric DNA histogram, is a prognostic factor in breast cancer. There are, however, some inherent difficulties in the estimation of SPF, such as the influence of debris, aggregates, and normal cells. Most of the available SPF calculation principles try to consider these difficulties, but so far no consensus has been reached with regard to which prin
Background: Official guidelines that promote evidence-based and cost-effective prescribing are of main relevance for obvious reasons. However, to what extent these guidelines are followed and their conditioning factors at different levels of the health care system are still insufficiently known. In January 2004, a decentralized drug budget was implemented in the county of Scania, Sweden. Focusing
PURPOSE: We measured serum levels of human glandular kallikrein 2 (hK2) in patients with prostate cancer treated with radical retropubic prostatectomy for clinically localized prostate cancer to determine whether preoperative hK2 levels discriminate stage pT2a/b from pathological stage T3a or greater cancer. This finding would help to predict preoperatively the organ confined versus non-organ conf
Historically, agriculturally induced CO2 release from soils has contributed to rising levels in the atmosphere. However, by using appropriate management, soils can be turned into carbon sinks. Many of the dryland regions of the world are characterised by degraded soils, a high incidence of poverty and a low capacity to invest in agriculture. Two well-proven soil organic matter models (CENTURY 4.0
Caloric restriction has been found to be protective against the development of type 2 diabetes mellitus (T2D) in experimental animal studies. However, studies examining this association in humans are limited. In the present study, we examined whether individuals with anorexia nervosa, one marker of severe caloric restriction in humans, have a low incidence of T2D by using several Swedish registrie
Background: To investigate the long-term effects of cholinesterase inhibitor (ChEI) therapy and the influence of sociodemographic and clinical factors on the use of community-based home help services (HHS) by patients with Alzheimer's disease (AD). Methods: This 3-year, prospective, multicenter study included 880 AD patients treated with donepezil, rivastigmine, or galantamine in a routine clinica
More scheduled outdoor stay is increasingly advocated for school children. This study measured 2(nd) , 5(th) and 8(th) graders' erythemal UV-exposure in September, March and May at four Swedish schools. We related those exposures, as fractions of total available ambient radiation, to the schools outdoor environments differing in amount of shade, vegetation, and peripheral city-scape quantified as
Background and purpose. The variability in target delineation for similar cases between centres treating paediatric and adolescent patients, and the apparent differences in interpretation of radiotherapy guidelines in the treatment protocols encouraged us to perform a dummy-run study as a part of our quality assurance work. The aim was to identify and quantify differences in the segmentation of ta
The aims of this study were to provide normative data for dual-energy X-ray absorptiometry (DXA) in 25-yr-old women and evaluate whether young adult Swedish women have bone mineral density (BMD) comparable with DXA manufacturer reference values and other equivalent populations. BMD at all sites was measured in the population-based Peak-25 cohort (n = 1061 women; age, 25.5 ± 0.2yr). BMD values were
Background: Adequate bowel preparation prior to colonic diagnostic procedures is essential to ensure adequate visualisation. Scope: This consensus aims to provide guidance as to the appropriate use of bowel preparation for a range of defined clinical circumstances. A consensus group from across Europe was convened and met to discuss appropriate bowel preparation. The use of polyethylene glycol (PE
Supplemental Instruction (SI) can be an efficient way of improving student success in difficult courses. Here, a study is made on SI attached to difficult first-year engineering courses. The results show that both the percentage of students passing a difficult first-year engineering course, and scores on the course exams are considerably higher for students attending SI, compared to students not attendi
Tissue factor (TF)-mediated protease activated receptor (PAR)-2 signaling is associated with a pro-migratory, invasive and pro-angiogenic phenotype in experimental models of breast cancer, and has been mechanistically coupled to phosphorylation of the TF cytoplasmic domain (pTF). However, the clinical relevance of these findings are unknown. Here, we provide first in vivo evidence of TF phosphoryl
The Lecanoromycetes is the largest class of lichenized Fungi, and one of the most species-rich classes in the kingdom. Here we provide a multigene phylogenetic synthesis (using three ribosomal RNA-coding and two protein-coding genes) of the Lecanoromycetes based on 635 newly generated and 3307 publicly available sequences representing 1139 taxa, 317 genera, 66 families, 17 orders and five subclass
