This chapter considers the problem of estimation of the transfer function of a continuous-time dynamic system in the presence of colored noise. Whereas parameter estimation can be made by means of a discrete-time maximum-likelihood algorithm, an operator transformation permits a continuous-time model parameterization. The method is useful in cases where it is important to estimate the coefficients

Three methods are suggested to identify and quantify flashback and flash forward events based on chemiluminescence recordings of swirling flames. The approaches differ in the procedure to determine the instantaneous flame position. The results revealed that the most robust method is to determine a threshold relative to the instantaneous maximum intensity. Analysis of the complete dataset indicated

This article is dealing with the work of a Catholic St Joseph Sisters in the Nordic countries, particularly in Denmark and Sweden, from the sisters’ arrival in 1856 to the 1920:ies. These Catholic sisters belonged to a French congregation called La Congregation des Sœurs de Saint-Joseph de Chambéry, which was founded at the beginning of the nineteenth century and whose motherhouse was in Chambéry

Popular Abstract in Swedish I vår omgivning finns det många bakterier, virus och parasiter som kan skada och göra människor sjuka. För att skydda oss mot angrepp av dessa sjukdomsalstrande organismer och andra skadliga ämnen har flera nivåer av skyddsmekanismer utvecklats. Huden, slemhinnorna och det låga pH-värdet i magsäcken är några av de yttre barriärer som hindrar många skadliga organismer atThe aim of this thesis was to characterise the biological functions of the superantigen staphylococcal enterotoxin H (SEH). Superantigens are highly immunostimulatory proteins, which crosslink T cells and antigen presenting cells (APCs). SEH is included in a family of staphylococcal enterotoxins (SEs) produced by certain strains of Staphylococcus aureus. The three-dimensional fold of SEH was dete

The Energy using products (EuP) directive proposed by the European Commission is often referred to as "the first Integrated Product Policy (IPP) directive". The main purpose of the directive is to ensure the free movement of EuP in the internal market as well as to improve the environmental performance of products throughout their life cycle. Product groups likely to be addressed through the direc

Galectins, a lectin family, have shown binding affinities towards b-galactosides. Galectins have been proposed to be involved in a wide range of functions like for example, cell growth, adhesion, migration, chemo taxis and apoptosis. They have also been associated with various cancer types. However, the detailed functions of galectins are still very much unknown. High affinity inhibitors towards t

Popular Abstract in Swedish Cancer i tjock- och ändtarm drabbar årligen drygt 5000 svenskar. En rad faktorer har satts i samband med tumöruppkomst i tarmen, bl a ärftlighet, inflammatorisk tarmsjukdom, kost och motion, men det är till stor del okänt hur dessa faktorer orsakar cancerutveckling. Genetiska förändringar styr tumörutvecklingen Tumörerna utvecklas oftast från ett godartat förstadium, Colorectal cancer is one of our most common malignancies and the second leading cause of cancer death worldwide. About 1/3 of the tumors are located in the rectum. Treatment advances such as the introduction of the standardized surgical technique total mesorectal excision (TME), pre-operative radiotherapy, and adjuvant chemotherapy have reduced the previously high local recurrence rates and improv

Certain strains of group A streptococci are known to bind IgA and/or IgG via a cell surface receptor, which may act as a virulence factor. The distribution of such receptors among routine clinical isolates was studied, using a total of 225 strains and an assay based on the binding of radiolabelled immunoglobulins. Among 194 throat strains isolated during three different time periods in two differe

Deviances in early event-related potential (ERP) components reXecting auditory and phonological processing are well-documented in children at familial risk for dyslexia. However, little is known about brain responses which index processing in other linguistic domains such as lexicon, semantics and syntax in this group. The present study investigated eVects of lexical-semantic priming in 20- and 24

The clinical spectrum of Trichomonas vaginalis infection varies from asymptomatic to mild, moderate or severe vaginitis. Nitric oxide and other reactive nitrogen radicals produced by immune effector cells are important cytotoxic and cytostatic mediators against several microorganisms including parasites. In the present study, inducible nitric oxide synthase (iNOS) and reactive nitrogen intermediat
