In this report, the technical and economical feasibility to produce higher alkanes from bio-glycerol has been investigated. The main purpose of producing this kind of chemicals would be to replace the fossil LPG used in upgraded biogas production. When producing biogas and exporting it to the natural gas grid, the Wobbe index and heating value does not match the existing natural gas. Therefore, th

By growth of Si on substrates that have been pre-patterned by electron-beam induced carbon nano-growth masks, nano-holes form at the Si surface. We have grown self-assembled Ge quantum dots in these holes by ultra high vacuum chemical vapour phase deposition (UHV-CVD). We usually find four dots in each hole. By varying the amount of deposited Ge, we can obtain either four dome-shaped or four pyram

"It is not the eyes that fool you, it’s not the ears that can’t hear It’s the darling conceptions of your time that makes you feel this way" Detta sjunger 1600-talsastronomen Galileo Galilei i denna artikel i FRAMTIDSBOKEN, och artikeln kretsar, precis som alla sex ingående artiklar, kring konceptuella problem knutna till vår tid och ett samhälle som är mer och mer uppkopplat. Dessa dilemman är

Servitut innebär normalt att en fastighet får nyttja en annan fastighet för ett visst bestämt ändamål. I Sverige finns det ca 600 000 registrerade officialservitut i fastighetsregistret. De allra flesta bildade vid lantmäteriförrättningar. Samtidigt finns det ca 650 000 inskrivna avtalsservitut i fastighetsregistret. Som jämförelse finns det ca 3,2 miljoner fastigheter, ca 60 000 ledningsrätter oc

Popular AbstractAvhandlingen tar sin empiriska utgångspunkt i en analys av hur historiskt betingade värden hanteras i samtida planering samt natur- och kulturmiljövård. Syftet är att därigenom förtydliga förutsättningarna för en hållbar landskapsutveckling avseende landskapets historiska värden. Analysen tar sin teoretiska utgångspunkt i tidsgeografi och kritisk realism. Perspektiven har använts fThis thesis is based on an analysis of how historically motivated values are treated in contemporary planning- and conservation practices. The aim is to discuss the premises of a sustainable landscape development regarding historical landscapes and heritage. The analysis takes its theoretical point of departure in time-geography and critical realism. These perspectives have been used to develop a

This paper details the findings of an assessment of the Swedish "application crisis" to universities, where some fields have experienced a drop in applications. There are also problems with throughput of students. Our team interviewed gymnasium pupils, guidance counselors, and first year students in selected disciplines at Lund University to find out how they made their decision to come to univers
