A Microcalorimetric Study of Resting and Activated Cellular Systems

Several cell types and nerve tissue have been studied using a combination of microcalorimetry and other methods. The heat production rate and its pH dependence of normal and transformed 3T3 cells were studied. The transformed cells manifested a higher heat production rate and a larger anaerobic contribution to the total catabolism than did the non-transformed cells. Moreover, the transformed cell

Synthesis and applications of analogues of Tröger's base as molecular tubes, receptor and ligands

Popular Abstract in Swedish Trögers bas är en molekyl som syntetiserades första gången 1887. Molekylen är stel, C2-symmetrisk och böjd i ca 90° vinkel och den formar en kiral hydrofob ficka. I denna avhandling beskrivs syntesen av nya analoger av Trögers bas. Aniliner, substituerade med halider i 2- och 3-position, har för första gången kondenserats till analoger av Trögers bas. Dessutom har det vTröger’s base was synthesized for the first time in 1887. The molecule is rigid, C2-symmetric and has a 90° angle, forming a chiral hydrophobic pocket. In this thesis, the synthesis of new analogues of Tröger’s base is described. 2- and 3-halo-substituted anilines have for the first time been condensed to Tröger’s base analogues. It has also been shown that anilines without substituents in para-po

Single-­molecule spectroscopy of π-­conjugated polymers

When applied to condensed-matter samples of large organic molecules, optical spectroscopy faces the problem of inhomogeneous broadening caused by the diversity of environments and conformations that sample molecules are subjected to. This severely limits the information that can be extracted from optical spectra. Single-molecule spectroscopy offers the most natural way to overcome this problem. Π-

Protozoan Acanthamoeba polyphaga as a potential reservoir for Campylobacter jejuni

We showed by a laboratory experiment that four different Campylobacter jejuni strains are able to infect the protozoan Acanthamoeba polyphaga. C. jejuni cells survived for longer periods when cocultured with amoebae than when grown in culture alone. The infecting C. jejuni cells aggregated in amoebic vacuoles, in which they were seen to be actively moving. Furthermore, a resuscitation of bacterial

Experimental and numerical study of ground vortex interaction in an air-intake

The airflow field around air-intake related geometries has been investigated experimentally and numerically. The configuration of the experimental set-up is used to model a jet engine running near the ground. The experiments have been carried out using both PIV and LDA techniques in order to obtain the mean and fluctuating velocity field as well as the low speed frequencies related to the system o

Skenet som bedrog: Mai Zetterling och det svenska sextiotalet

Popular Abstract in Swedish Mai Zetterling (1925-1994) var under fyrtiotalet skådespelare, både på Dramatens scen och i populära svenska filmer. Under sextiotalet regisserade hon fyra långfilmer. Dessa filmer ? Älskande par (1964), Nattlek (1966), Flickorna (1968) och Dr. Glas (1969) ? bemöttes emellertid allt mer negativt av de svenska filmkritikerna. Under återstoden av sitt liv regisserade ZettMai Zetterling (1925-1994) was a popular actress in the 1940s. In the 1960s, she directed four feature films. The films ? Loving Couples (1964), Night Games (1966), The Girls (1968) and Dr. Glas (1969) ? were met with increasing hostility by Swedish critics, however, and after the 1960s, Mai Zetterling only directed two more feature films in her life, the British Scrubbers (1982) and the Swedish A
