Porous materials are among the most commonly used materials for noise and vibration reduction in modern transportation vehicles. To design, industrially relevant, weight and cost effective noise and vibration measures, there is a need for general prediction models capable of representing the elasto-acoustic behaviour of such materials. The objective of the present work, is to contribute to the mod

A fracture mechanics model for analysis of crack initiation and propagation in wood is defined and applied. The model has the advantage of being simple, yet it enables reasonably general and accurate analysis commonly associated with more complex models. The present applied calculations are made by means of the finite element method and relate to progressive cleavage fracture along grain. The calc
Bacterial meningitis is a rare presentation for congenital immunodeficiency, but meningococcal invasive diseases and meningitis have been associated with late complement component deficiencies and properdin deficiency. A 5(1)/(2)-y-old boy of non-consanguineous parents was admitted to our hospital with meningococcal septic shock. He had previously been suffering from recurrent respiratory infectio
When coupling a model of the biological reactor to a model of the settler, difficulties appear because of the different representations used for the particulate material. A combined model of the entire activated sludge process needs to include an algorithm for the dynamic propagation of the biological components of the particulate material through the secondary clarifier. In particular, this is of
OBJECTIVE: Neutrophil deposition in tissues (leukosequestration) after shock may produce local tissue injury from proteases and high-energy oxygen species released from sequestered neutrophils. The initial step in the binding of neutrophils to capillary endothelium is the interaction of adhesion molecule (selectin) receptors between neutrophils and endothelial cells. We quantified leukosequestrati
Avhandlingen belyser mötet mellan de konstnärliga och pedagogiska dimensionerna i lärares pedagogiska arbete. Genom att undersöka lärares erfarenheter av musikalproduktion i skolan avser studien att fördjupa kunskapen om det professionella lärararbetet som grundar sig i lärares pedagogiska och konstnärliga utövande och praktiska kunskap. Studien tar sin utgångspunkt i en musikalproducerande verksaThe present thesis examines the meeting between the artistic and the pedagogical dimensions in the work of teachers. The main aim is to describe the learning in practice, emerging from a collective creative process. The point of departure is teachers' experience of a musical-production as part of the pedagogical work in school. Research questions are: 1) What are the implications of being a teach
dWe construct the effective chiral Lagrangian for chiral perturbation theory in the mesonic odd-intrinsic-parity sector at order p(6). The Lagrangian contains 24 in principle measurable terms and no contact terms for the general case of N-f light flavors, 23 terms for three and 5 for two flavors. In the two flavor case we need a total of 13 terms if ail external singlet vector field is included. W
Mg-protoporphyrin monomethyl ester (MPE) is a biosynthetic intermediate of chlorophyll and converted by MPE cyclase to protochlorophyllide. Limited availability of MPE has so far hampered cyclase research. In a new, simplified, method MPE was prepared from freeze dried bchE mutant Rhodobacter capsulatus DB575 cells by extraction with acetone/H2O/25% NH3. Isolated MPE was identified by absorption a
Vascular smooth muscle cells (VSMCs) in the intact vascular wall are differentiated for contraction, whereas the response to vascular injury involves transition towards a synthetic phenotype, with increased tendency for proliferation. Platelet-derived growth factor (PDGF) is thought to be important for this process. We investigated expression and functional coupling of PDGF receptors (PDGFRs) alph
BACKGROUND: Some low-incidence antigens in the Rh blood group system (e.g., VS, Rh32, FPTT) are expressed by more than one Rh complex. We describe a new low-incidence antigen that is present on RBCs with the partial D phenotypes, DIIIa or DOL, on RN RBCs and on one example of STEM+S RBCs. STUDY DESIGN AND METHODS: Standard hemagglutination testing was performed with two sera that agglutinated DIII
Popular Abstract in Swedish Studien beskriver och analyserar strategisk förändring i tre svenska tidningsföretag. I studien beskrivs hur företagen utvecklades från enaffärs-verksamheter till multiaffärs-verksamheter. Studien pekar på hur denna utveckling framförallt ska ses som resultat av etableringen och spridningen av en ny kunskapsformation. Ett centralt innehåll i den kunskapsformationen var The dissertation examines power and knowledge in strategic changes. It is a study of changes in three Swedish newspaper companies which developed from single-business to multi-business corporations. It is suggested that this transformation was based upon the establishment and reproduction of a new knowledge formation. This knowledge was the knowledge of strategy, particularly the classical perspec
BACKGROUND: The pathophysiologic mechanisms behind the development of liver steatosis during total parenteral nutrition (TPN) and the possible relationship to alterations of lipoprotein lipase activities in different tissues are not fully known. It is also unknown whether continuous and discontinuous administration of TPN affect lipid metabolism differently. METHODS: TPN, including 8.4 g of trigly
The Camassa-Holm equation is a conservation law with a non-local flux that models shallow water waves and features soliton solutions with a corner at their crests, so-called peakons. In the present paper a finite-volume method is developed to simulate the dynamics of peakons. This conservative scheme is adaptive, high resolution and stable without any explicit introduction of artificial viscosity.
The aim of this study was to evaluate interobserver agreement in the results of Doppler measurements of peak systolic velocity (PSV), time-averaged maximum velocity (TAMXV) and the color content of tumor scans in extrauterine pelvic tumors. The results of transvaginal color and spectral Doppler examinations of 66 extrauterine pelvic masses obtained by two observers experienced in ultrasonography w
