We give a proof of the Nirenberg-Treves conjecture: that local solvability of principal type pseudodifferential operators is equivalent to condition (Psi). This condition rules out sign changes from - to + of the imaginary part of the principal symbol along the oriented bicharacteristics of the real part. We obtain local solvability by proving a localizable a priori estimate for the adjoint operat

St. Birgitta as prophet in the Old Testament sense: inspired person who acts and speaks on God's behalf to various social classes and individuals, telling her addressees what should be done and avoided, sometimes also the future (hardly the important feature, however). Her universe is totally biblical, something that can be proved through linguistic and narrative correspondences between the Revela

REHABILITERING I SJÄLVHJÄLPSGRUPP är en ledarhandbok. Den är i första hand skriven för ledare i Värkstadsgrupper och Hälsosantgrupper, både i verkliga livet och i cyberspace. Värkstadsgrupper är öppna samtalsgrupper för människor med värk, smärta och olika utbränningsdiagnoser, dvs. majoriteten av de långtidssjukskrivna. Hälsosantgrupper är slutna samtalsgrupper som bygger på filmer från autentisk

I den här boken visar författaren hur flera historiska och teologiska faktorer samverkat till att skapa bilden av motsatsförhållandet mellan judendom och kristendom, vilket starkt bidragit till den idétradition som möjliggjorde Förintelsen och som fortfarande lever kvar inom kyrka och akademi. Enligt den traditionella synen har kristendomen uppfattats som judendomens definitiva motsats. Vanligtvis

This thesis describes the physical chemistry of softwood kraft lignin in aqueous alkaline solutions. Both fundamental and applicational aspects are discussed. Kraft lignin originates either from pulp fibres or from black liquor produced by kraft cooking. In wood, the lignin is an anionic macromolecular colloid of relatively high molecular mass that is gradually depolymerised under the kraft cook.

This paper presents the manufacturing experience of an outer rotor permanent magnet synchronous machine with four different stators. The advantageous features of powder technology and molding techniques are tested when constructing and manufacturing the stators for a 28-pole 30-slot machine. The selected machine configuration is taking advantages of the concept of the modular windings and at the s

In 1986, Thames Television broadcast a series of programmes on British cinema. In one of them, dedicated to the Free Cinema documentary movement of the 1950s, and the new wave of films it triggered in Britain in the 1960s, 70s, and 80s (particularly Anderson’s own), Lindsay Anderson took the opportunity to ridicule the prominent box office and Academy Award success of Chariots of Fire, which premi
