The structure and dynamics of a turbulent partially premixed methane/air flame in a conical burner were investigated using laser diagnostics and large-eddy simulations (LES). The flame structure inside the cone was charecterized in detail using LES based on a two-scalar flamelet model, with the mixture fraction for the mixing field and level-set G-function for the partially premixed flame front pr

Water column (dissolved/suspended phase, sediment traps) and sediment data (pore-water, solid-phase sediment) were combined with stable Pb and Pb-210 isotope data to trace the early diagenetic behaviour and geochemical cycling of Pb in Lake Laisan, a lake which has received large quantities of anthropogenic Pb since the early 1940s. Early diagenetic remobilisation of Pb is indicated by a subsurfac

Artemia salina has, for the first time, been used as test organism for acute toxicity of leachate water from three landfills (the municipal landfills at Kristianstad, Sweden and Siauliai, Lithuania, and an industrial landfill at Stena fragmenting AB, Halmstad, as well as for leachate from Kristianstad treated in different ways in a pilot plan). Artemia can tolerate the high concentrations of chlor

The majority of patients with von Willebrand disease (VWD) have a mild bleeding tendency that primarily involves mucosal bleeding. Some patients with the disorder, however, have severe episodes of mucosal or joint bleeding that can hamper daily activities and lead to significant joint impairment. Experience in the setting of severe hemophilia has shown the feasibility and benefits of prophylactic

The aim of this study was to test the potential of four isolates of ectomycorrhizal (EM) fungi to utilize organic nitrogen (N) at two different substrate pHs. The organic N source ((1)5N labelled lyophilised fungal mycelium) was mixed with either untreated peat/sand mixture (pH 4.9) or peat/sand mixture limed to a pH of 5.9 and put in cylindrical containers added to each pot. The content of the co

CONTEXT AND OBJECTIVE: During medical education and training, the values and attitudes of medical students are shaped both by knowledge and by role models. In this study, the aim was to compare the views of first- and final-year students concerning patients with different medical conditions. PARTICIPANTS AND METHOD: In the spring of 1998 all first- and final-year medical students at Göteborg and L

Particle emissions from residential wood combustion in small communities in Northern Sweden can sometimes increase the ambient particle concentrations to levels comparable to densely trafficked streets in the center of large cities. The reason for this is the combination of increased need for domestic heating during periods of low temperatures, leading to higher emission rates, and stable meteorol

This paper investigates the relationship between institutional trust in the health-care system, i.e. an institutional aspect of social capital, and self-rated health, and whether the strength of this association is affected by access to health-care services. The 2004 public health survey in the Scania region of Sweden is a cross-sectional study; a total of 27,963 respondents aged 18–80 years answe

A single intradermal injection of the adjuvant-oil squalene induces T cell mediated arthritis in DA rats. The chain of events leading from nonspecific provocation of the immune system to arthritis is largely unknown. Previous studies have demonstrated that lymph node (LN) cells are of pathogenic importance, i.e. cells from LNs draining the injection site can transfer arthritis to naïve DA rats. Re

In this work, a real-time sampling/analytical method for on-line measurements of two newly discovered cyclomaltodextrinases (CDases) has been developed and evaluated. This novel methodology not only allows the final products to be investigated, but it also reveals enzyme-specific differences in the degradation pathways during the hydrolysis of different substrates, which is a great advantage in th

The aim of this study was to describe the clinical characteristics in relation to final amputation level in diabetic patients with foot ulcers. In a prospective series, 187 consecutively presenting patients were investigated. From admission until final outcome, the patients were treated by a multidisciplinary team both as in- and out-patients. All the patients had one or more signs of neuropathy a

We measured bacterial growth on phototransformed dissolved organic matter (DOM) leached from eight different primary producers. Leachates (10 mg C liter(-1)) were exposed to artificial UVA + UVB radiation, or kept in darkness, for 20 h. DOM solutions were subsequently inoculated with lake water bacteria. Photoproduction of dissolved inorganic carbon (DIC), ranging from 3 to 16 mug C liter(-1) h(-1

Research on event-related potential (ERP) correlates of auditory deviance-detection in newborns provided inconsistent results; temporal and topographic ERP characteristics differed widely across studies and individual infants. Robust and reliable ERP responses were, however, obtained to sounds (termed 'novel' sounds), which cover a wide range of frequencies and widely differ from the context provi

Popular Abstract in Swedish I den första avhandlingen på svenska om den finlandssvenske estetikern, filosofen och författaren Hans Ruin (1891–1980) förenas ett intresse för det litterära uttrycket med ett intresse för människan bakom orden. Litteraturen som mänskligt dokument, som spåret efter en människa, och dess funktion som överbringare av erfarenheter och insikter står i centrum för framställThe first dissertation in Swedish of the Finno-Swedish aesthetician, philosopher and writer Hans Ruin (1891–1980) combines an interest in the literary expression with an interest in the man behind the words. Literature as a human document, as the footprint of a human being, and its function as a bearer of experiences and insights is at the heart of the characterisation. The title of this dissertat

Thin films of CeO2 with and without a thin layer of copper oxide were prepared by rf magnetron sputtering on surfaces of alpha-Al2O3 (sapphire) substrates. Careful characterisation of the surfaces was performed down to the atomic level using high-resolution electron-microscopy, atomic force microscopy, and X-ray photoelectron spectroscopy. Surprisingly, the as-deposited, corrugated ceria surfaces,

A numerical and analytical investigation is performed on a dissolved air flotation (DAF) pilot tank by using the residence time distribution (RTD) of the conservative dye rhodamine measured with a fluorometer. The experiments are numerically analyzed with regard to the total volume of the DAF tank separation zone in order to detect differences between observed separation zone flow structures in pr

We have developed force-field parameters for the hydrogen-abstraction transition state of aliphatic hydroxylation by cytochrome P450 using the Q2MM approach. The parametrization is based on quantum chemical (B3LYP) transition-state structures and Hessian matrices for 24 diverse substrate models (14 in the training set and 10 in the test set). The force field is intended to be applicable to any dru

Two-dimensional SIDS-PAGE gel electrophoresis using post-run staining is widely used to measure the abundances of thousands of protein spots simultaneously. Usually, the protein abundances of two or more biological groups are compared using biological and technical replicates. After gel separation and staining, the spots are detected, spot volumes are quantified, and spots are matched across gels.
