Polyelectrolytes and polyelectrolyte complexes (PECs) are characterized by many useful properties that endow them with high potential in different areas of biotechnology. This thesis describes the development and analyses of some new systems and methods utilizing poly(acrylic acid) (PAA), poly(methacrylic acid) (PMA), poly (N-ethyl-4-vinylpyridinium bromide) (PEVP) and PMA-PEVP complexes. The mode

On the basis of one specific event during World War two, the Swedish Defence Loan campaign in 1940, the text studies how the Bernadotte family – as one homogenous entity as well as separate family members – acted and staged themselves in the media and the public sphere.

Socio-Legal research is, in some respects, founded on a paradox in that, while it claims or aspires to be an interdisciplinary subject with particular ties with sociology, the majority of its practitioners are based in law schools, and have not received any systematic training in either sociological theory or research methods. There are, of course, many academics from other disciplines who have co

Properties of nanostructures realized by bottom-up techniques are often different from their bulk counterparts.(1) Here we present a study of a nano-Schottky contact formed at the interface between a gold catalytic particle and an epitaxially grown GaxIn1-xAs/InAs nanowire. Selective electrical connections formed to the catalytic particle on one side and to the In As segment on the other side allo

The transport of ions related to the penetration of chlorides into concrete has been studied in the field by drilling 100-mm concrete cores from a marine bridge column. A 4-year-old concrete column in Sweden was selected. The concrete was of high quality (i.e., frost- and sulfate-resistant, with a low-heat, low-alkali portland cement with a maximum water-cement ratio of 0.40) according to new Swed

This article deals with the early development of the Jesus prayer in Early Christian monasticism of the 4th to the 7th century. It proceeds in two steps. First, a quite uniform matrix of practices and aims related to three early monastic authors (John Cassian, Diadochus of Photike, and John Climacus) is discerned. It is evident that the practice is not clearly defined in this period. It is also ap

Large Eddy Simulation of swirling flows in a typical gas turbine burner has been carried out. The goal has been to study the effects of swirl number, inlet velocity profile, confining wall distance, Reynolds- and Schmidt-number effects on the flow and turbulent mixing. The results show that the inlet velocity profile, the confinement and the swirl have a substantial effect on the resulting flow-fi

Popular Abstract in Swedish Intresset för metallbaserade läkemedel har växt stadigt de senaste årtionden. Kemins utveckling ger oss hela tiden mer förståelse och bättre verktyg för studier av olika metallkomplex och deras biologiska verkning. Utvecklingen och kunskapen har ökat så mycket, att nya specialiserade discipliner har vuxit fram, som till exempel bio-oorganisk och biometallorganisk kemi. Various metal complexes have been used in medicine traditionally, although their use was often connected with mystery and with a lack of empirically (clinically) proven effect. In modern times, the development of biochemistry, bioinorganic and bioorganometallic chemistry allows us more in-depth understanding of biological action of metal containing substances. Among metal-containing drugs used tod
