Monte Carlo calculations of protein binding to affinity ligands tethered to a surface by polymers have been done and analyzed with statistical mechanical perturbation theory. The interaction of the polymers with the surface, the solvent and the protein has been varied. Different solution conditions of the polymers have been investigated, varying from collapsed polymer structures on a surface to st

BACKGROUND: The pancreas harbors growth factors such as the epidermal growth factor (EGF) family. The physiological and pathophysiological roles of growth factors in normal pancreas remain unsettled. Human pancreatic cancer overexpresses the EGF receptor, and the ligands EGF and transforming growth factor alpha (TGF-alpha). The aim of the present experiments was to study the effect of TGF-alpha in
Potentially pathogenic bacteria, such as Escherichia coli and Vibrio cholerae, become non-culturable during stasis. The analysis of such cells has been hampered by difficulties in studying bacterial population heterogeneity. Using in situ detection of protein oxidation in single E. coli cells, and using a density-gradient centrifugation technique to separate culturable and non-culturable cells, we
The bacterium Helicobacter pylori is the causative agent for peptic ulcer disease. Bacterial adherence to the human gastric epithelial lining is mediated by the fucosylated Lewis b (Leb) histo-blood group antigen. The Leb-binding adhesin, BabA, was purified by receptor activity-directed affinity tagging. The bacterial Leb-binding phenotype was associated with the presence of the cag pathogenicity
The aim of this report has been to find a model suitable for the Swedish industry when assessing fire frequencies in industrial facilities. The report also contains a guide to the selection of initial fires, and the evaluation of the fire scenarios resulting from those fires, when fire risk assessments in industrial facilities is being done. A summary of data concerning the reliability of sprinkle
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
