With the increasing concerns about our environment and human health, more and more stringent emission limits have been specified. These adopted and still coming emission limits require and promote more accurate, less experiential methods to design and develop the combustors. In this thesis, computation fluid dynamics (CFD) technology, based on large eddy simulation (LES) and level set G-equation m

Syftet med denna studie var att beskriva förändringar i det fysiska aktivitetsmönstret – ökad, minskad eller oförändrad fysisk aktivitet – hos en grupp studenter under en tremånadersperiod. I studien deltog 155 studenter. Två av de formulär som ingår i den transteoretiska modellen (förändringsstadier och beteendestrategier) användes. Slutsatser: • Om studierna planeras bättre skulle fler studente

The effects of a new calcium antagonist, isradipine (PN 200-110) on postpartum uterine activity and the maternal cardiovascular system were investigated. Uterine activity was recorded by a microtip transducer catheter inserted transcervically within 45 min of normal vaginal delivery. 0.5 mg of isradipine was given as a bolus injection during 5 min to 7 women with spontaneous uterine activity and 1

The release gamma-aminobutyric acid (GABA) and ATP from rat beta cells was monitored using an electrophysiological assay based on overexpression GABAA or P2X2 receptor ion channels. Exocytosis of LDCVs, detected by carbon fiber amperometry of serotonin, correlated strongly (similar to 80%) with ATP release. The increase in membrane capacitance per ATP release event was 3.4 fF, close to the expecte

This article deals with probable causes for missing values when using the Revised Class Play instrument for peer assessment of social behavior. The study was conducted with 10-13 year old primary school children in Sweden. The findings reveal that missing values may be caused by the cognitive and linquistic complexity of the instrument (RCP), as well as by gender stereotypes. The results indicated

Solvent extraction of phosphoric acid with Alamine 336 and tri-n-octylamine in toluene has been investigated. The activity of phosphoric acid is expressed as a polynomial of ionic strength and Bromley's model for electrolyte solutions is employed for calculation of ionic activity coefficients. Three species R3N (H3P04) n with n = 1, 2 and 3 in the organic phase are taken into account for explanati

Fifty knees scheduled for a total knee prosthesis were randomized in two groups. Both groups had a noncemented fixation of the porous-coated implants but one group received a prosthesis with ceramic coating on the porous surface of the implant. The knees were evaluated with RSA technique regarding micromotion the first two years. There were less micromotion in the coated group. The results indicat

The intra-molecular, proton-coupled electron transfer from a tyrosine residue to covalently linked tris-bipyridine ruthenium(III) complexes in aqueous solution (Ru-III-TyrOH --> Ru-II-TyrO(.) + H+) is studied in two complexes. The Ru-III-TyrOH state is generated by laser flash-induced photo-oxidation in the presence of the electron acceptor methyl viologen. The reaction is shown to follow either a

A novel surface protein of the bacterial species Moraxella catarrhalis that displays a high affinity for IgD (MID) was solubilized in Empigen and isolated by ion exchange chromatography and gel filtration. The apparent molecular mass of monomeric MID was estimated to approximately 200 kDa by SDS-PAGE. The mid gene was cloned and expressed in Escherichia coli. The complete mid nucleotide gene seque

This paper explores the quasi-deformation scheme devised in [1, 3] as applied to the simple Lie algebra sl(2)(F) for specific choices of the involved parameters and underlying algebras. One of the main points of this method is that the quasi-deformed algebra comes endowed with a canonical twisted Jacobi identity. We show in the present article that when the quasi-deformation method is applied to s

Action plan for the conservation of Psora vallesiaca Psora vallesiaca is red-listed in Sweden and assigned to the category Critically Endangered (CR). In Sweden it is known from one locality on Öland where it grows in a small population of about 30 individuals. In the spring of 2006, four new localities were discovered on Gotland. The main distribution of Psora vallesiaca streches from the Mediter

This study investigated whether there is an association between bone density and features of the metabolic syndrome in relation to hormonal status. All women aged 50 to 59 years living in a defined geographic area in Sweden were offered a health assessment program including blood glucose, lipid profile, blood pressure, and bone densitometry. Women were divided into 3 groups according to their horm

Popular Abstract in Swedish Fuktbuffring i inomhusmiljön är ytmaterialens förmåga att, genom absorption och desorption, dämpa luftens fuktighetsvariationer. Fuktbuffring spelar en viktig roll i förståelsen av risker för biologisk tillväxt i ytmaterial, t.ex. mögel på väggar och husdammskvalster i sängar. Därigenom är fuktbuffring viktig ur hälsosynpunkt. Förutom hälsoaspekterna är kunskap om fuktbMoisture buffering in the indoor environment is the ability, through absorption and desorption, of surface materials to attenuate the moisture variations of the indoor air. Moisture buffering plays an important role in understanding the risks for biological growth in surface materials in the indoor environment, e.g., mold growth on walls and house dust mites in beds, and thereby also have an impac
