Making Analogues of Tröger's Base – Fused oligomers, endo/exo isomers and twisted amides

Popular Abstract in English The ability to make aromatic cleft compounds is of importance in the field of molecular recognition where many interactions of the guest with the receptor are based on interactions involving aromatic receptor moieties leading to π-π and cation-π interactions, as well as hydrophobic interactions commonly seen. One attractive framework for aromatic cleft compounds is TrögThe centenarian Tröger’s base (TB) was envisaged as scaffold for the construction of tubular-shaped cleft molecules due to its the remarkable structural properties. This endeavor started with the synthesis of the three possible diastereomers of a linear symmetrically fused tris-TB analogue, the anti-anti, the syn-syn, and the syn-anti. All three diastereomers showed unprecedented stability to acid

Word order in the Italian DP in child and adult acquisition

It is generally agreed that children are able to acquire two languages to which they are exposed from birth as two L1s. Little attention has been drawn to cases when one language develops slower and is weaker in different aspects. A question under debate is whether the weaker language develops as an L2 rather than as an L1. The goal of this paper is to contribute to the understanding of the weaker

Modeling Lateral Transshipments and Perishable Items in Inventory Systems

This thesis deals with two main areas in the field of stochastic inventory theory; ateral transshipments and perishable items. In the first part of this thesis we give an introduction to the field of inventory theory, and discuss some previous literature connected to the research presented in this thesis. In the second part, the original research which defines this thesis is presented in the form

Applying the Pump and Leak Hypothesis. An experimental and theoretical investigation of the principles of ion regulation and excitability in the crustacean stretch receptor neuron.

An invertebrate nerve cell preparation, the lobster stretch receptor neuron, was investigated with respect to maintenance of its resting voltage, intracellular ion concentrations and excitability using voltage clamp technique and ion-selective microelectrodes. It was found that the resting voltage (-65 mV) of microelectrode impaled cells is caused by (a) a homogenous population of K+ channels whic

Computation of the acoustic field in an annular gas turbine combustion chamber using a hybrid approach

The acoustic field generated by flow unsteadiness in a model annular gas turbine (GT) combustion chamber is determined using a hybrid approach. In the flow solver the semi-compressible Navier-Stokes equations are resolved using LES as turbulence model. The acoustic solver is based on an inhomogeneous wave equation, where the instantaneous source terms are computed from the LES data in each time-in

Dagspress, sport och doping : Medieskandaler i ett samtida Sverige

Popular Abstract in Swedish I avhandlingen beskrivs och analyseras den svenska dagspressens hantering av doping och dopingöverträdelser inom internationell elitidrott. Artiklarna studeras med hjälp av följande tre frågeställningar: (1) Vad utmärker medieinnehållet om sport och doping? (2) Vilken bild av den sociala ordningen skymtar fram i detta mediematerial? (3) Vad berättar medieskandaler kringThe study analyses how the Swedish press dealt with doping and transgressions of the doping rules within international professional sports between 1996 and 2004. Three main research questions have been used in the research process: (1) What characterizes these media texts about sports and doping? (2) How is the social order pictured in the media texts? (3) What do media scandals about sport stars
