This paper presents an auction procedure which is of particular interest when short execution times are of importance. It is based on a method for approximating the bidders' preferences over two types of items when complementarity between the two may exist. In particular, linear approximations of the bidders' indifference curves are made. The resulting approximated preference relation is shown to

Popular Abstract in Swedish Kolhydrater är viktiga inte bara som bränsle och strukturgivande egenskaper, vilket var uppfattningen för 25 år sedan. De ingår även som en mycket viktig del i hur celler kommunicerar med varandra. Det har de senaste åren visat sig vara kolhydrater inblandade i en mängd signalering- och igenkänningsmekanismer. Några exempel: när bakterier angriper en cell är det oftast Artificial, amfiphilic, and biomimetic receptors soluble in water were synthesized via attaching polar amino acids to hydrophobic back-bones possessing a surface suitable for hydrophobic interactions. The hydrophobic back-bones chosen in this thesis were anthracene and dibenzobarrelene structures. A route to an efficient synthesis of a dibenzobarrelene backbone with two sets of orthogonal reactivi

Detta är slutrapporten från vår undersökning av psykiska konsekvenser för lokförare av de påkörningar de varit med om på järnvägsspåren. Tidigare har det publicerats tre delrapporter i projektet (Briem, de Lima & Siotis, 2004; Briem, Siotis & de Lima, 2007a, 2007b), och resultaten pekar entydigt i samma riktning. De indikerar att dödsolyckorna på järnvägsspåren har långvariga och ofta svår

Philosophers have stressed the need to distinguish between explanatory (motivating) reasons and justifying (good) reasons. The distinction is often illustrated with an example of someone doing something that is intended to appear at the outset as incomprehensible. The next step is then to add some further details about the agent — typically some information about his or her beliefs and desires — p

Abstract Sweden has experienced a dramatic change from being a belligerent greatpower in the 17th and 18th centuries to becoming a peaceful small nation in the 19th and 20th centuries. The country has not been involved in war for over 180 years. Modern Sweden has established more or less peaceful relations with other countries. This thesis focuses on the 19th century as beeing an important period

The development of selective sorbents for the separation of various molecules, preferentially biomolecules, is described in this work. Affinity ligands were immobilized on small silica particles and used in high-performance liquid affinity chromatography (HPLAC). With this technique, it is possible to perform fast, selective and efficient bioseparations. Methods were developed for the preparation
