On the basis of existing detailed kinetic schemes a general and consistent mechanism of the oxidation of hydrocarbons and the formation of higher hydrocarbons was compiled for computational studies covering the characteristic properties of a wide range of combustion processes. Computed ignition delay times of hydrocarbon -oxygen mixtures (CH4-, C2H6-, C3H8-, n-C4H10-, CH4 + C2H6-, C2H4, C3H6-O-2)
Objective. To compare the efficacy and safety of intra-articular injections of two different hyaluronan preparations and placebo in patients with knee osteoarthritis. Methods. In a randomized, patient- and observer-blind, placebo-controlled and multicentre trial with parallel groups, 210 patients, aged 60 yr or above, with knee osteoarthritis were included in a per protocol analysis. The patients
Combustion of CO, ethyl acetate and ethanol was studied over CuOx/Al2O3, CuOx-CeO2/Al2O3, CuMn2O4/Al2O3 and Mn2O3/Al2O3 catalysts. It was found that modification of the alumina with ceria before subsequent copper oxide deposition increases the activity for combustion of CO substantially, but the effect of ceria was small on the combustion of ethyl acetate and ethanol, The activity increases with t
We used an enrichment technique to isolate 18 novel di and tri microsatellites for the socially monogamous lizard Tiliqua rugosa. These loci were amplified in conjunction with previously described loci in two and three PCR multiplexes for T. rugosa and the endangered T. adelaidensis, respectively. The loci were highly polymorphic in both species, exhibiting between 2 and 32 alleles with observed h
Popular Abstract in Swedish Summary in swedish Perinatal dödlighet bland invandrare från Afrikas Horn. Vikten av erfarenhet, rationellt tänkande och traditioner vid riskbedömning av gravida invandrarkvinnor. Avhandlingen visar att barn till kvinnor i invandrargrupper från Afrika söder om Sahara (majoriteten från Somalia och Etiopien), har högre perinatal dödlighet jämfört med barn till svenska kThis thesis is an exploration of the possible effects of maternal country of origin on the risk of perinatal mortality (PNM). Increased risk of PNM was found among infants of foreign-born women delivering in a Swedish hospital between 1990-1995. After adjustment for risk factors, however, the finding only held true for a subgroup of women from Ethiopia and Somalia (ES). In searching for the mecha

Whether risk factors for epithelial ovarian cancer (EOC) differ by subtype (i.e., dualistic pathway of carcinogenesis, histologic subtype) is not well understood; however, data to date suggest risk factor differences. We examined associations between reproductive and hormone-related risk factors for EOC by subtype in the European Prospective Investigation into Cancer and Nutrition (EPIC) cohort. A
The prediction of transcription factor binding sites in genomic sequences is in principle very useful to identify upstream regulatory factors. However, when applying this concept to genomes of multicellular organisms such as mammals, one has to deal with a large number of false positive predictions since many transcription factor genes are only expressed in specific tissues or cell types. We devel
Objective To evaluate the effectiveness of oral glucosamine in subgroups of people with hip or knee osteoarthritis (OA) based on baseline pain severity, body mass index (BMI), sex, structural abnormalities and presence of inflammation using individual patient data. Methods After a systematic search of the literature and clinical trial registries, all randomised controlled trials (RCTs) evaluating
To support countries in reforming their research and innovation systems, the Directorate-General for Research & Innovation (DG RTD) of the European Commission set up a Policy Support Facility (PSF) under the European Framework Programme for Research & Innovation ‘Horizon 2020’. It aims to support Member States and associated countries in improving their national science, technology and inn
Aim: To evaluate aerobic exercise in migraine and co-existing tension-type headache and neck pain. Methods: Consecutively recruited persons with migraine and co-existing tension-type headache and neck pain were randomized into an exercise group or control group. Aerobic exercise consisted of bike/cross-trainer/brisk walking for 45 minutes, three times/week. Controls continued usual daily activitie
Fracture behavior of an ultra thin Aluminium foil was studied. For very short crack lengths, fracture has been followed in the scanner electronic microscope (SEM) with a tensile stage. A single edge notched tension specimen was used. Crack length and applied load during the crack growth were measured. These results have been used to calculate fracture strength using linear elastic fracture mechani
Context While vascular endothelial growth factor-targeted therapy and mammalian target of rapamycin inhibition are effective strategies in treating clear cell renal cell carcinoma (ccRCC), the most effective therapeutic approach for patients with non-clear cell RCC (non-ccRCC) is unknown. Objective To systematically review relevant literature comparing the oncological outcomes and adverse events o
Background: Imatinib causes increased turnover of stromal collagen, reduces collagen fibril diameter, enhances extracellular fluid turnover and lowers interstitial fluid pressure (IFP) in the human colonic carcinoma KAT-4/HT-29 (KAT-4) xenograft model. Methods: We compared the effects of imatinib on oxygen levels, vascular morphology and IFP in three experimental tumor models differing in their co
PURPOSE: To assess the patient and identify the risk factors for infectious complications in conjunction with urological procedures and suggest a model for classification of the procedures. METHOD: Review of literature, critical analysis of data and tentative model for reducing infectious complications. RESULTS: Risk factors are bound to the patient and to the procedure itself and are associated w
Design is often described as a profession where the result of the work is future oriented. Herbert Simon defined it as work that aims at “changing existing situations into preferred ones” . This may refer to a design process where the result can be very unpredictable even if the goal is thoroughly outlined. David Pye has portrayed this performance as “workmanship of risk” which differs from “workm
OBJECTIVE: Genome-wide association studies have begun to elucidate the genetic architecture of type 2 diabetes. We examined whether single nucleotide polymorphisms (SNPs) identified through targeted complementary approaches affect diabetes incidence in the at-risk population of the Diabetes Prevention Program (DPP) and whether they influence a response to preventive interventions.
