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

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-

This paper describes a control structure assessment method in anindustrial control system. The method uses available signals to evaluate if agiven signal can be used for additional feedforward control action to improvethe performance of a control loop.

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

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

This book chapter discusses queer theory in relation to visual culture.

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

Let A be a subset of the real line. We study the fractal dimensions of the k-fold iterated sumsets kA, defined as kA = {a(1) ... + a(k) : a(i) is an element of A}. We show that for any nondecreasing sequence {alpha(k)}(k=1)(infinity) taking values in [0,1], there exists a compact set A such that kA has Hausdorff dimension ak for all k >= 1. We also show how to control various kinds of dimensions s

This note studies lumped-delay approximations of distributed-delay elements arising in various problems involving delay compensation or preview utilization. Several approaches to reduce implementation complexity, understood as the number of delays required to attain a required accuracy level, are put forward. First, we derive the H2-optimal coefficients for a given delay pattern. This can be seen
