The main objective of this thesis was to identify methods for the detection of ß-lactam resistance in staphylococci, bacteria often causing nosocomial infections. Detection of ß-lactam resistance in these species is difficult due to strong regulation of genes encoding for the two main resistance mechanisms, ß-lactamase production and the penicillin-binding protein (PBP) 2?. ß-lactamase has high af

The aims of this study were: to compare the cartilaginous outline of the femoral head obtained on arthrograms with those on MR images and to correlate it to the bony head outlines on conventional radiograps; to study early, postoperative cartilaginous and bony remodeling of the femoral head, after proximal femoral varus derotation extension osteotomy, with MR imaging and conventional radiography;

The ECL cells in the stomach produce, store and secrete a variety of secretory products, such as histamine and chromogranin A-derived peptides (e.g. pancreastatin). The functional significance of the ECL cells can be expected to reflect the nature/bioactivity of the secreted products. Although the anticipated peptide hormone of the ECL cells remains unidentified, ECL-cell histamine is recognized a

In this paper we analyze how the spatiality of interactions influences trust creation in multi-site corporate innovation projects. By drawing on insights from the discussion on initial and gradual trust and connecting them to contributions from the field of economic geography, we examine different antecedents of trust and their dependence on face-to-face interaction. We thereby illustrate the comp

The equilibrium self-assembly of cationic surfactants in bulk solution and at negatively-charged silica substrates is investigated experimentally and theoretically. The surfactants used are quaternary ammonium salts, both monovalent (DoTAB, TTAB, CTAB) and divalent (DoPPDAC). The adsorption of DoPPDAC to silica, in the absence or presence of added electrolyte, is studied with the technique of null

This thesis is about how and in opposition to what punk is defined and lived out by punks in Sweden and Indonesia. Arguing against the previous research’s presumption that subcultural meaning constitutes a single set of meaning, this study points to two patterned sets of meanings, each constructed out of several different definitions of the mainstream as well as the subcultural authentic. Conseque

This thesis presents new cryptanalysis results for several different stream cipher constructions. In addition, it also presents two new stream ciphers, both based on the same design principle. The first attack is a general attack targeting a nonlinear combiner. A new class of weak feedback polynomials for linear feedback shift registers is identified. By taking samples corresponding to the linear

I denna edition med inledning och kommentar berätta den nyprästvigde prästen Bengt Högrell (1832–1922) om sina upplevelser av sin första tjänstetid som adjunkt hos prosten Schånberg. Den ger en bred inblick i villkoren för en adjunkt som bodde hos sin förman, avlönades av denne och var beroende av de offer han fick ta upp av församlingarna, samt av inkomsterna från den privatskola han själv drev.

Sweden of the eighteenth and nineteenth centuries was visited and toured by a number of British author-travellers, whose subsequently published views of and on the country and its people are examined and presented in this thesis. Using as primary sources British-published monographs deriving, wholly or in part, from an experienced Sweden of c.1770-1865, it has been possible to identify and define

This paper presents a pilot study on the prosodic marking of a contrastive topic in Southern Swedish. A test sentence was elicited in three experimental conditions: initial focus; final focus; contrastive topic (initial word) plus focus (final word). F0 patterns were analysed in recordings of 10 speakers. A majority of the speakers distinguished clearly between the conditions, but speakers employe
