This thesis consists of five papers (Paper A-E) on statistical modeling of diffusion processes. Two papers (Paper A & D) consider Maximum Likelihood estimators for non-linear diffusion processes. An offline Maximum Likelihood estimator is derived in Paper A, and it is shown that this estimator is computationally more efficient than other Maximum Likelihood estimators. The offline algorithm is

The azimuthal distributions of photons and charged particles with respect to the event plane are investigated as a function of centrality in Pb-208 + Pb-208 collisions at 158 (.) A GeV/c in the WA98 experiment at the CERN SPS. The anisotropy of the azimuthal distributions is characterized using a Fourier analysis. For both the photon and charged particle distributions the first two Fourier coeffic

Popular Abstract in Swedish Våra vita blodceller bildas i benmärgen och när de mognat färdigt hamnar de i blodcirkulationen. Det finns olika typer av vita blodceller och varje typ har sin egen funktion. En speciell typ av vit blodcell, nämligen den myeloida vita blodcellen (neutrofilen), spelar en mycket viktig roll i kroppens första försvar mot invaderande bakterier. När bakterier kommer in i kroIn myelopoiesis, neutrophils and monocytes/macrophages are formed from a common myeloid precursor cell in the bone marow. During maturation of neutrophils, cytoplasmic granules are formed in the cells and the content of these granules is critical for the function of neutrophils in the first line of defense against invading microorganisms. The Bactericidal/Permeability-Increasing protein (BPI) is s

Three-dimensional imaging of fuel tracer planar laser-induced fluorescence in a homogeneous charge compression ignition (HCCI) engine is presented. A high-speed multiple Nd:YAG laser and detection system, in combination, with a scanning mirror, are used to collect eight images, with an equidistant separation of 0.5 mm. Three-dimensional isoconcentration surfaces calculated from the data are visual

Clinical research, when children involved, may cause difficult ethical problems for both caregivers and parents. Informed consent has to be obtained from the parents and from the child depending on age and maturity. The concept of informed consent is complicated and depending on the ability of communication between the professionals and the parents. The aim of the study was to illuminate parents l

Innovations are necessary for growth and competitiveness, but few are taking place in the food industry. Clusters and networks in regions/countries are seen as one way of increasing the chances to compete, based on Porter's theories in 1990. Before that some articles existed about agglomeration, clustering of industries etc. but not many examples in the food industry seem to have been studied. Thi

A gene coding for the multi-copper phenol oxidase laccase has been isolated from the white-rot basidiomycete Trametes oersicolor. The gene, which is preceded by a TATA box and a pyrimidine-rich region, is predicted to contain ten introns. The mature translation product, preceded by a 22-residue signal peptide, should consist of 498 residues. Comparisons with Edman degradation data of peptides from

An introduction to and edition of a previously unpublished legend for the Canonization Day of the Swedish national saint, Birgitta Birgersdotter. The legend exists today in one single manuscript, Uppsala University Library, ms. C 24, written in the second half of the fifteenth century. The legend has three main parts: the first describes the holy life of St Birgitta in the form of two "sermons"; t

Cross-linked agarose particles (Sepharose CL-6B) and baker's yeast cells were found to adhere to siliceous supports end-grafted with boronate-containing copolymers (BCCs) of N,N-dimethylacrylamide at pH >= 7.5, due to boronate interactions with surface carbohydrates of the particles and the cells. These interactions were registered both on macroscopic and on molecular levels: the BCCs spontaneousl

Previous studies demonstrated that neuropeptides are transported with fast axonal transport. Considerable amounts (30-40%) of anterogradely transported peptides accumulated distal to a crush, apparently recycling to the cell bodies. In the present study, we used primary and compartmented cultures of sympathetic cervical ganglia (SCG) to address questions on the origin of the recycling peptides. In

Aims and objective. To evaluate patient- reported health outcomes of a multidisciplinary group educational programme for people with Parkinson's disease ( PD), delivered as part of routine clinical practice. Background. Studies suggest that educational programmes for people with PD have potential to improve patients' perceived health and well- being. However, controlled trials of multidisciplinary

The aim of the study was to evaluate, from a technical and economic standpoint, the enzymatic processes involved in the production of fuel ethanol from softwood. Two base case configurations, one based on simultaneous saccharification and fermentation (SSF) and one based on separate hydrolysis and fermentation (SHF), were evaluated and compared. The process conditions selected were based mainly on

We consider homogeneous density functions for proving almost global attractivity of the zero equilibrium in a homogeneous system. It is shown that the existence of such a function is guaranteed when the equilibrium is asymptotically stable, or in the more general case, when there exists a nonhomogeneous density function for the same system satisfying some reasonable conditions.

A new species of fungus gnats in the genus Cordyla Meigen, 1803, C. bomloensis sp. n., is described based on adult material from southwestern Norway. Both the male and the female are described, photographed and their terminalia figured. The new species belongs in the C.fusca-group. It seems to be most closely allied to C. brevicornis (Staeger, 1840) and C. pusilla Edwards, 1925 from which it is di
