When biomass is used to produce fuels and green products by thermochemical conversion, the ability to handle or remove the fine particle phase in the product gas is crucial. The product gas from biomass gasification contains relatively volatile organic compounds (“tar”) condensed on nonvolatile cores of, for example, aggregated soot particles and char. The problems are, for example, that particles
In the development of new food products, more knowledge is needed about the occurrence and quantity of food-borne pathogens in the food chain to be able to implement effective control measures and assure food safety. In addition, improved understanding of how environmental factors and food preservatives effect the microbial virulence expression in foods will enable the formulation of new strategie
Popular Abstract in Swedish Ändamålet med studien var att identifiera prognostiska och etiologiska riskfaktorer för melanom och dess relation till histopatologi. Studie 1-3 innefattade 711 patienter från 1965-1989. Vi fann en mediantjocklek som varierade mellan 1,1 och 1,4 mm, utan något statistiskt förändring genom åren och en ökning av andelen tunna tumörer (<0,8 mm) som var statistiskt signifikThe purpose was to study the prognostic and aetiologic risk factors for melanoma in correlation to histopathology. Paper 1-3: Thin tumours (<0.8 mm), tumours with inflammation and median age at diagnosis were signifcantly increasing in 711 CMM patients during the period 1965-89. No difference was found in median thickness. Factors that significantly improved prognosis were; thin tumour thickness,
Objective: To determine the within- and between-patient variability in the concentrations of synovial fluid, serum and urine markers of joint tissue metabolism in a cohort of patients with knee pain and cartilage changes consistent with early-stage knee osteoarthritis. Design: Samples of synovial fluid, serum, and urine were obtained from 52 patients on eight different occasions during 1 year, as
Purpose: To develop concise, patient-focussed, up to date, evidence-based, expert consensus recommendations for the management of hip and knee osteoarthritis (OA), which are adaptable and designed to assist physicians and allied health care professionals in general and specialist practise throughout the world. Methods: Sixteen experts from four medical disciplines (primary care, rheumatology, orth
Molecular hydrogen exists in two spin-rotation coupled states: parahydrogen and orthohydrogen. Due to the variation of energy with rotational level, the occupation of ortho- and parahydrogen states is temperature dependent, with parahydrogen being the dominant species at low temperatures. The equilibrium at 20 K (99.8% parahydrogen) can be reached by natural conversion only after a lengthy process
Background Safety data on cancer risks following tumour necrosis factor a inhibitors (TNFi) in patients with spondyloarthritis (SpA) (here defined as ankylosing spondylitis (AS), undifferentiated spondarthropaties (SpA UNS), psoriatic arthritis (PsA)) are scarce. Our objective was to assess risks for cancer overall and for common subtypes in patients with SpA treated with TNFi compared with TNFi-n
The release of toxic gases due to natural/industrial accidents or terrorist attacks in populated areas can have tragic consequences. To prevent and evaluate the effects of these disasters different approaches and modelling tools have been introduced in the literature. These instruments are valuable tools for risk managers doing risk assessment of threatened areas. Despite the significant improveme
Objectives: Study formal and informal care of community-living older people in the Swedish National study of Aging and Care (SNAC). Design: Cross-sectional, population based cohort. Setting: Three areas in Sweden: Municipality of Nordanstig, Stockholm and Skåne County. Participants: 3,338 persons ≥72 years. Measurements: Patterns and amounts of informal and formal care by cognition and area of res
Objective: To characterize meal patterns across ten European countries participating in the European Prospective Investigation into Cancer and Nutrition (EPIC) calibration study. Design: Cross-sectional study utilizing dietary data collected through a standardized 24 h diet recall during 1995–2000. Eleven predefined intake occasions across a 24 h period were assessed during the interview. In the p
According to the fictitious crack model, the crack width is infinitely thin at crack initiation and with further loading the crack opens, but no material exists in the cohesive zone. Despite that, the crack is assumed to able to sustain a load. While this is possible at the atomic level, it is not a realistic assumption for the macroscopic behavior we are considering. Invoking the mass conservatio
A multi-wavelength lidar system was used to detect free-flying birds passing over Athens, Greece. The location is strategically located in one of the important migratory corridors for birds migrating between Europe and Africa. Multiwavelength aerosol lidars are operated regularly across Europe in the frame of EARLINET. Here, the feasibility of using this existing infrastructure for assessing fluxe
This joint report includes the five legal national reports on the taxation of partnership in the Nordic countries. The general contents of these reports are summarized and thoroughly analyzed in Liselotte Madsen’s General report, published in this issue of the NTaxJ. For additional information, details on legislative measures etc. we find it important, however, to also publish the national reports
This joint report includes economic national reports on the taxation of partnership in the Nordic countries, except Denmark.

Background: Tyrosine kinase inhibitors (TKIs) have increased survival dramatically for patients with chronic myeloid leukemia (CML), but continuous administration of these drugs may elicit long-term toxicity. Objective: To investigate the incidence of vascular events in patients with CML treated with first-and second-generation TKIs. Design: Retrospective cohort study using nationwide population-b
UNLABELLED: Breast, ovarian, and prostate cancers are hormone-related and may have a shared genetic basis, but this has not been investigated systematically by genome-wide association (GWA) studies. Meta-analyses combining the largest GWA meta-analysis data sets for these cancers totaling 112,349 cases and 116,421 controls of European ancestry, all together and in pairs, identified at P < 10(-8) s
Risk factors of stroke/thromboembolism (TE) and major bleeding, and incidence of these events in specific age categories in warfarin-treated patients with mechanical heart valves (MHV) are uncertain. Our objective was to calculate event rates in specific age categories and identify risk factors for adverse events. Methods and results We identified 4,810 treatment periods with MHV between January 2
