Introductory Study of Variable Valve Actuation for Pneumatic Hybridization

Urban traffic involves frequent acceleration and deceleration. During deceleration, the energy previously used to accelerate the vehicle is mainly wasted on heat generated by the friction brakes. If this energy that is wasted in traditional IC engines could be saved, the fuel economy would improve. One solution to this is a pneumatic hybrid using variable valve timing to compress air during decele

"Ur klumpig lera stiger skönhets vilja". Konflikten mellan ande och drift i Birger Sjöbergs *Konferensman"

Birger Sjöbergs dikt "KOnferensman" ur Kriser och kransar (1926) tolkas mot bakgrund av psykoanalytiska föreställningar, vilka Sjöberg sannolikt mött hos psykoanalytikern Poul Bjerre.Det som läker psykosen hos huvudpersonen är en estetiskt fattad teologi, där konst, drömmar och andra andliga produkter visar att drift och ande hör samman, inte bör fattas som dikotomiska eller antagonistiska krafter

Absorbed Dose Determination and Characteristics of Degraded Electron Beams: Application to Intraoperative Radiation Therapy

Popular Abstract in Swedish Intraoperativ strålbehandling (IORT) innebär att en hög engångsstråldos ges direkt under operation till den kirurgiskt frilagda tumören och/eller kvarvarande tumörrester. Den vanligaste typen av strålning som används vid denna behandlingsform är elektronstrålning från konventionella medicinska linjäracceleratorer. Det krävs dock att ett speciellt applikatorsystem finns The aim of this work was to quantify limitations of and uncertainties in commonly used dosimetric techniques for relative absorbed dose determination in degraded electron beams, such as those encountered in intraoperative radiation therapy (IORT) and small-electron-field radiotherapy. Three different detector types were investigated with regard to measurements of output factors and relative absorb

A Europe of the Member States or of the Citizens? - Two Philosophical Perspectives on Sovereignty and Rights in the European Community

Today’s debate about the EC and its future can be grouped along two main lines. On the one side are those who hold that the EC is a grouping of sovereign states for the purposes of international cooperation. On the other side are those who maintain that the EC is a new political society that unites the citizens of Europe in a new political and legal community where the question of the sovereignty
