Streptococcus pyogenes is one of the most common bacteria infecting humans. One of the factors contributing to the disease-causing properties is the secreted streptococcal cysteine proteinase, SpeB, which degrades several host proteins in connective tissue and circulation. SpeB activity depends on the transformation from an inactive precursor, zymogen, into a mature proteinase. We show that the im

The syntax of imperatives makes an interesting test case when investigating word order, verb raising and cliticisation across languages and their acquisition. This paper looks at language differentiation, i.e. language-specific parameter setting, in the imperative constructions of a bilingual child, "Katla", acquiring a verb-raising language, Icelandic, as well as English, not a verb-raising langu

I discuss how a difference in the correlation length longitudinally and transversely with respect to the jet axis in e+e- annihilation, arises naturally in a model for Bose-Einstein correlations based on the Lund string picture. This difference is, due to the longitudinal stretching of the field, more apparent in genuine three-particle correlations. They can therefore be used as a sensitive probe

Den vackraste platsen i lärdomsstaden Lund är "Botan" - en botanisk trädgård med intressanta växter från jordens alla hörn. I denna praktfullt illustrerade bok tas vi under sakkunnig ledning med på en promenad genom fuktdrypande regnskogar, kryddoftande medelhavssnår och torra öknar, vi slår oss ned vid solspeglande näckrosdammar och beundrar träd som det växer tulpaner på - allt inom murarna krin

The thesis deals with circuit-level aspects of CMOS buffer SRAMs where the data throughput rate is a more important metric than access time or storage capacity. One aspect is the increased write cycle related power consumption that is the consequence of a high write ratio combined with a long word-length. That is addressed through the invention of a new bit-line operation mode which allows lower

Johannes Filoponos skrift De opificio mundi är formellt en kommentar till skapelseberättelsen i Genesis men i verkligheten en polemik mot hans samtida Kosmas Indikopleustes och dennes uppfattning om universums struktur. I sin Topographia Christiana hävdade Kosmas, att jord och himmel tillsammans bildade en fyrkantig tvåvåningsbyggnad med valvtak, och fann stöd för denna uppfattning i Bibeln. Filop

Assistive robots have received considerable research attention due to the increase of the senior population around the world and the shortage of care-givers. However, limited attention has been paid to involving seniors in the de-sign process in order to elicit their attitudes and perceptions of having their own robot. This study addresses this issue. We conducted a workshop with 14 Swe-dish senio
