The pathway from the deep cerebellar nuclei to the inferior olive, the nucleo-olivary pathway, is known to be inhibitory. The physiological and temporal properties, as well as the localisation, of the nucleo-olivary pathway were characterised in the decerebrate ferret. The results were used to investigate the suggestion that the nucleo-olivary pathway is part of a negative feedback system for the

Popular Abstract in Swedish Hjärnan är ett komplext system, som är uppbyggd av många olika sorters celler. Alla dessa celler har sitt ursprung i en speciell typ av cell, stamcellen. Neurala stamceller är omogna celler som har förmågan att genom delning både föröka sig själva genom att bilda fler stamceller, och ge upphov till de olika mogna celltyper som finns i hjärnan. Mycket av intresset för de

Popular Abstract in Swedish Vår kropp är uppbyggd av flera olika typer av stödjevävnader tex ben, brosk, muskler och hud. Den utgör kroppens stomme och bidrar med både stödjande och elastiska funktioner i kroppen. Brosk är en specialiserad form av bindväv som bekläder alla ledytor i kroppen och dess specifika sammansättning förser leden med en i det närmaste friktionslös rörelseförmåga. Broskets

Resistivity imaging in combination with drill hole information is a powerful tool in geotechnical site investigations. Traditionally the resistivity data is inverted with a 2D smooth inversion algorithm, resulting in a minimum structure model. In the geological interpretation it can be difficult to determine sharp layer boundaries in these models. An additional parameterized inversion of resistivi

This thesis presents the works on fabrication and measurements done with micro cantilevers and a micro channel system, fabricated in the photo-resist SU-8. SU-8 is a polymer patterned by UV lithography which offers a cheap and fast processing and is an interesting alternative to standard Si techniques. For the structures intended here, it proved to be a well suited material and promising results w

Popular Abstract in Swedish Undersökningen syftar till att klargöra hur överföringen av hellsingtexter till barnpubliken har en motsvarighet i texternas form och hur detta bidrar till att forma diktarens poetiska universum. Texterna står i centrum och perspektivet är brett. Eftersom barnlitteratur är en litterär sidoström behövs andra teorier och metoder än för annan litteratur. Jag fokuserar den This thesis deals with Lennart Hellsing's works, and especially his texts for small children, from 1945 to 2000. In an introductory survey the oral transmission of literature is discussed in relation to orality and literacy. The presupposition is that there are similarities between oral culture and texts for the very young. Hellsing's production is surveyed along with his position as a poet, his i

VOR, the versatile optimal resolution chopper spectrometer, is designed to probe dynamic phenomena that are currently inaccessible for inelastic neutron scattering due to flux limitations. VOR is a short instrument by the standards of the European Spallation Source (ESS), 30.2m moderator to sample, and provides instantaneous access to a broad dynamic range, 1-120 meV within each ESS period. The sh

The roof dual bound for quadratic unconstrained binary optimization is the basis for several methods for efficiently computing the solution to many hard combinatorial problems. It works by constructing the tightest possible lower-bounding submodular function, and instead of minimizing the original objective function, the relaxation is minimized. However, for higher-order problems the technique has
